NOW THEREFORE, in consideration of the premises and covenants contained herein, it is hereby agreed as
follows: 
 Article I

Person. 
 “Cash Settlement Averaging Period” means, with respect to any Note to be converted, the twenty five
(25) consecutive Trading Day period beginning on, and including, the second (2nd) Trading Day immediately after the date the conversion notice for such Note is delivered to the Conversion Agent (whether physically or, if such Note is held
in the form of a Global Security, through the Depositary’s conversion program); provided, however, that if such conversion notice is received after the date of issuance of a notice of Redemption pursuant to Section 3.03 of

prior to the applicable Redemption Date; provided, further, that with respect to any conversion of such Note arising solely by reason of the occurrence of a Fundamental Change, the Cash Settlement Averaging Period for such Note means
the twenty five (25) consecutive Trading Days beginning on and including the twenty-eighth (28th) scheduled Trading Day prior to the Fundamental Change Repurchase Date relating to such Fundamental Change. 

The term “close of business” means 5:00 p.m., New York City time. 

“Closing Sale Price” of any share of Common Stock on any Trading Day means the closing sale price of the Common Stock
(or if no closing sale price is reported, the average of the closing bid and closing ask prices or, if more than one in either case, the average of the average closing bid and the average closing ask prices) on such Trading Day as reported in
composite transactions for the principal U.S. securities exchange on which the Common Stock is traded or, if the Common Stock is not listed on a U.S. national or regional securities exchange, as reported by Pink OTC Markets Inc. In the absence of
such a quotation, the Closing Sale Price will be determined by a nationally recognized securities dealer retained by the Company for that purpose. The Closing Sale Price will be determined without reference to extended or after-hours trading.

  
 2 

 “Collective Election” means, with respect to a Conversion Right Adjustment
Event in which holders of Common Stock shall have the opportunity to elect the form of consideration to receive pursuant to such Conversion Right Adjustment Event, the actual election made by a majority of holders of Common Stock in such Conversion

of U.S. Treasury bonds with equivalent (or nearly equivalent) remaining terms from the applicable Redemption Date to, but excluding, April 1, 2016. 
 “Credit Agreement” means the Credit Agreement, dated as of August 24, 2011, by and among Omnicare, Inc., the lenders parties thereto, SunTrust Bank, as Administrative Agent, JPMorgan

accordance with the Indenture) on such Trading Day. 

  
 3 

 “Daily Net Shares” means, with respect to any Trading Day, a number of

the Daily Net Shares shall be subject to adjustment pursuant to the second proviso of Section 12.02(c).

event will the Excluded Subsidiaries, either individually or collectively, hold more than ten percent (10%) of the consolidated assets of the Company and its Domestic Subsidiaries as of the end of any fiscal quarter or account for more than ten
percent (10%) of the consolidated revenue of the Company and its Domestic Subsidiaries during the most recent four (4) quarter period (in each case determined as of the most recent fiscal quarter for which the Company has internal

sentence are complied with.

following has occurred: 
  

	 	(1)	the Company becomes aware of (by way of report or other filing pursuant to Section 13(d) of the Exchange Act, proxy, written notice or otherwise) the consummation
of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as such term is defined in Rule 13d-3 and Rule 13d-5 under the Exchange Act) becomes the “beneficial owner”
(as such term is defined in Rule 13d-3 and Rule 13d-5 under the Exchange Act), directly or indirectly, of more than fifty percent (50%) of the Company’s Capital Stock that is at the time entitled to vote in the election of the

transactions, of all or substantially all of the Company’s assets and those of the Company’s Subsidiaries taken as a whole to any “person” (as such term is used in Section 13(d)(3) of the Exchange Act), other than:

  

	 	(a)	any transaction: 

  

	 	(i)	that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of the Company’s Capital Stock and pursuant to which
transaction the holders of the Company’s Voting Stock immediately prior to such transaction have the right to exercise, directly or indirectly, fifty percent (50%) or more of the total Voting Power of all shares of the Capital Stock
entitled to vote generally in elections of directors of the continuing or surviving Person immediately after giving effect to such transaction; or 

  

	 	(ii)	any merger primarily for the purpose of changing the Company’s jurisdiction of incorporation and resulting in a reclassification, conversion or exchange of
outstanding shares of Common Stock solely into shares of common stock of the surviving entity; or 

  

	 	(4)	a Termination of Trading; 

 provided,
however, that a Fundamental Change will be deemed not to have occurred if more than ninety percent (90%) of the consideration in the transaction or transactions (other than cash payments for fractional shares and cash payments made in
respect of dissenters’ appraisal rights) which otherwise would constitute a Fundamental Change under clause (1) or (3) above consists of shares of common stock, depositary receipts or other certificates representing common equity
interests traded or to be traded immediately following such transaction on the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market and, as a result of the transaction or transactions, the Notes become convertible
solely into such common stock, depositary receipts or other certificates representing common equity interests (and any rights attached thereto). 

  
 5 

 “Guarantee” means a guarantee other than by endorsement of negotiable
instruments for collection in the ordinary course of business, direct or indirect, in any manner including, without limitation, by way of a pledge of assets or through letters of credit or reimbursement agreements in respect thereof, of all or any

	 	(2)	other agreements or arrangements designed to protect such Person against fluctuations in interest rates or foreign exchange rates. 

“Holder” means a Person in whose name a Note is registered. 

“Indebtedness” has the meaning ascribed to it in the Base Indenture, except that, notwithstanding anything to the
contrary in the Indenture or the Notes, Indebtedness does not include any liability for federal, state, local or other taxes or any settlements or judgments relating to governmental litigation or investigations. 

“Issue Date” means April 3, 2012. 
 “Last Reported Sale Price” has the same meaning ascribed to Closing Sale Price; provided, however, that the Last Reported Sale Price of the Capital Stock or similar equity

“Non-Stock Change of Control” means a transaction described in clause (1) or clause (3) of the definition of a
Fundamental Change in this Section 1.01, where ten percent (10%) or more of the consideration for the Common Stock (other than cash payments for fractional shares and cash payments made in respect of dissenters’ appraisal

the Indenture, (A) the term “interest” includes Contingent Interest, if any, but without duplication; and (B) references to currency shall mean the lawful currency of the United States of America; and (ii) as used in this
Eighth Supplemental Indenture, the terms “herein,” “hereof” and other words of similar import refer to this Eighth Supplemental Indenture as a whole and not to any particular article, section or other subdivision of this Eighth
Supplemental Indenture. To the extent this Eighth Supplemental Indenture or the Notes amends or otherwise modifies any article, section, provision, paragraph, clause or other text of the Base Indenture, each reference in this Eighth Supplemental
Indenture, the Base Indenture or the Notes to such article, section, provision, paragraph, clause or other text shall, for purposes of the Notes, be deemed to be a reference to such article, section, provision, paragraph, clause or other text as
amended or modified by this Eighth Supplemental Indenture and the Notes. 
 Article II 

THE NOTES AND GENERAL PROVISIONS 

2.01. Title and General Terms. Subject to and in accordance with Section 2.03 of the Base Indenture, the Company
hereby establishes the Notes as a series of Securities to be issued under the Indenture with the title “3.75% Convertible Senior Subordinated Notes Due 2042.” The principal amount of the Notes shall mature on the Maturity Date, unless such
Note is no longer outstanding at such time or the principal amount has theretofore been accelerated in accordance with the Indenture. The Notes shall not be secured by any collateral. All payments on the Notes shall be made in the lawful currency of
the United States of America. 
 2.02. Aggregate Initial Principal Amount. Subject to being increased by the
Company from time to time as shall be stated in an Officers’ Certificate, the aggregate initial principal amount of the Notes which may be authenticated and delivered pursuant to this Eighth Supplemental Indenture (except for Notes
authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 2.08, 2.09, 2.12, 3.06 or 9.05 of the Base Indenture and except for Notes which, pursuant to Section 2.04 of the
Base Indenture, are deemed never to have been authenticated and delivered) is three hundred and ninety million dollars ($390,000,000). The Company may issue additional Notes from time to time hereunder, subject to the provisions of Section 2.04
of the Base Indenture. All Notes issued on the Issue Date together with any such additional Notes issued under this Eighth Supplemental Indenture will be treated as a single class of securities under the Indenture. 

2.03. Form. The Notes will be Registered Securities issued in registered form in minimum denominations of $2,000 and
integral multiples of $1,000 in excess thereof. Notwithstanding anything to the contrary in the Indenture or the Notes, neither the Company nor the Trustee shall be obligated to issue any Note that whose principal amount is not $2,000 or an integral
multiple of $1,000 in excess thereof. The Notes shall be initially issued in the form of one or more Global Securities substantially in the form of Exhibit A hereto. The initial Depositary with respect to the Notes shall be DTC. Each Note
shall be dated the date of its authentication. The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Eighth Supplemental Indenture, and the Company, the Guarantors and the Trustee, by their
execution and delivery of this Eighth Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of the Indenture, the
provisions of the Indenture shall govern and be controlling to the extent of such conflict. 
 2.04. Payment on Global
Securities. Except as provided in the immediately following paragraph, principal and interest on the Notes will be paid (i) on Notes held in the form of Global 

  
 10 

 
Securities, to the Depositary or its nominee in immediately available funds; (ii) on any definitive Note that is not held in the form of Global Securities and that has an aggregate principal
amount of five million dollars ($5,000,000) or less, by check mailed to the Holder of such Note; and (iii) on any definitive Note that is not held in the form of Global Securities and that has an aggregate principal amount of more than five
million dollars ($5,000,000), by wire transfer in immediately available funds at the election of the Holder of such Note, which election is duly delivered to the Trustee at least fifteen (15) Business Days before the relevant Interest Payment
Date or other payment date, as applicable. 
 At the Maturity Date, the Company will pay the principal and interest (i) on
Notes held in the form of Global Securities, to the Depositary or its nominee in immediately available funds; and (ii) on definitive Notes that are not held in the form of Global Securities, at the Company’s office or agency in New York
City, which initially will be the Corporate Trust Office of the Trustee in New York City. 
 2.05. Certain Amendments to the
Base Indenture. 
 (a) Notwithstanding anything to the contrary in the Indenture or the Notes, the text of the fourth
(4th) paragraph of Section 2.08 of the Base Indenture shall, for purposes of the Notes, be replaced in its entirety with the following text: “Notwithstanding anything to the contrary in the Indenture or the Notes, a Note held in the
form of a Global Security shall not be exchanged in whole or in part for a Note registered in the name of any Person other than the Depositary or one or more nominees thereof; provided, however, that a Note held in the form of a Global
Security may be exchanged for a Note registered in the name of any Person designated by the Depositary in the event that (i) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global
Security or such Depositary has ceased to be a ‘clearing agency’ registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days; (ii) the Company receives a request by or on behalf of the
Depositary in accordance with customary procedures following a request of the beneficial owner of such Note seeking to enforce its rights under such Note or the Indenture; or (iii) the Company elects, at any time in its sole discretion, to
discontinue use of the system of book entry transfer through any Depositary. Any Note that is held in the form of a Global Security and that is exchanged pursuant to clause (i) above shall be so exchanged in whole and not in part, and any Note
that is held in the form of a Global Security and that is exchanged pursuant to clause (ii) or (iii) above may be exchanged in whole or from time to time in part as directed by the Depositary (in the case of clause (ii)) or by the Company
(in the case of clause (iii)).” 
 (b) Notwithstanding anything to the contrary in the Indenture or the Notes, the text of
Section 4.03 of the Base Indenture shall, for purposes of the Notes, be replaced in its entirety with the following text: “At any time when the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Company shall file with the Trustee, within fifteen (15) days after it actually files the same with the SEC (regardless of when the same is required to be filed with the SEC), each annual, quarterly or current report, information or
proxy statement other report which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act; provided, however, that the Company shall not be required to file or deliver to the Trustee any
material for which the Company has sought and received, or is seeking, confidential treatment by the SEC. The Company also shall comply with the other provisions of TIA Section 314(a). Delivery of such reports or statements to the Trustee is
for informational purposes only, and the Trustee’s receipt of the same shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance
with any of its covenants in the Indenture (as to which the Trustee is entitled to rely conclusively on Officers’ Certificates).” 

  
 11 

 (c) Notwithstanding anything to the contrary in the Indenture or the Notes, (i) the
word “Restricted” shall, for purposes of the Notes, be stricken from the text of Section 4.05 of the Base Indenture; and (ii) the phrase “of successor” in Section 1.04(f) of the Base Indenture shall be replaced
with the phrase “or successor”. 
 (d) Notwithstanding anything to the contrary in the Indenture or the Notes, the
address of the Trustee in Section 14.02 of the Base Indenture shall, for purposes of the Notes, be replaced with the following: 
 U.S. Bank National Association 
 1349 Peachtree Street, NW 

Suite 1050 

Atlanta, Georgia 30309 
 Attention: Account Manager – Omnicare 
 and, solely with respect to
Section 4.02 of the Base Indenture and Sections 2.04 and 12.02(j) hereof, 
 U.S. Bank National Association

 Corporate Trust Services 
 100 Wall Street 
 16th Floor Window 

New York, NY 10005 
 Attention: Account Manager – Omnicare 
 (e) Notwithstanding anything to the
contrary in the Indenture or the Notes, the first sentence of the second (2nd) paragraph of Section 7.07 of the Base Indenture shall, for purposes of the Notes, be replaced with the following sentence: “The Company shall indemnify the
Trustee and its officers, directors, employees and agents against any and all losses, liabilities or expenses incurred by any of them arising out of or in connection with the acceptance or administration of the Trustee’s duties under this
Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and defending themselves against any claim (whether asserted by the Company or any Holder or any other person) or
liability in connection with the exercise or performance of any of the Trustee’s powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to their gross negligence or bad faith.” 

2.06. Interest. 
 (a) Interest shall accrue on the principal amount of the Notes at the rate per annum equal to three and three quarters percent (3.75%). The Company will pay interest on the Notes, semi-annually in
arrears, on April 1and October 1 of each year (each such date, an “Interest Payment Date”), with the first payment to be made on October 1, 2012, to holders of record at 5:00 p.m., New York City time, on the
immediately preceding March 15 and September 15, respectively (each such date, the “Regular Record Date,” and the Interest Payment Date immediately following each Regular Record Date shall be deemed to be the Interest
Payment Date that “corresponds” to such Regular Record Date), in each case except as provided in Section 3.01 and Section 4.01(a) and in the immediately following paragraph of this Section 2.06(a).
Interest on the Notes will accrue on the principal amount from, and including, the most recent date to which interest has been paid or provided for or, if no interest has been paid, from, and including, April 3, 2012, in each case to, but
excluding, the next Interest Payment Date or the Maturity Date, as the case may be. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

  
 12 

 On the Maturity Date, the Company will pay accrued and unpaid interest on each Note to the
Person to whom the Company pays the principal amount of such Note, instead of to the Holder on the preceding Regular Record Date. 
 (b) Without duplication, interest shall accrue on Defaulted Interest, if any, pursuant to the second (2nd) paragraph of Section 2.14 of the Base Indenture. 

(c) In addition to the foregoing, (i) beginning with the six (6) month period beginning on, and including, April 1, 2020, if
the Contingent Interest Trading Price of the Notes for each Trading Day of the five (5) consecutive Trading Day period (the “Contingent Interest Measurement Period”) ending on, and including, the second (2nd) Trading Day
immediately preceding the first day of any six (6) month period (each such period, a “Contingent Interest Period”) from, and including, an Interest Payment Date to, but excluding, the next Interest Payment Date is equal to or
greater than the Upside Trigger, then the Company shall pay contingent interest (“Contingent Interest”) to the Holders in accordance with this Section 2.06(c) and (ii) beginning with the six (6) month period
beginning on and including April 1, 2019, if the Contingent Interest Trading Price of the Notes for each Trading Day of the Contingent Interest Measurement Period ending on, and including, the second (2nd) Trading Day immediately preceding the
first day of any Contingent Interest Period is less than or equal to the Downside Trigger, then the Company shall pay Contingent Interest to the Holders in accordance with this Section 2.06(c). 

The amount of Contingent Interest payable per $1,000 principal amount of Notes in respect of any Contingent Interest Period, if
applicable, shall (i) in the event that Contingent Interest is payable as a result of the Upside Trigger, be equal to one quarter of one percent (0.25%) of the average Contingent Interest Trading Price per $1,000 principal amount of the Notes
during the five (5) consecutive Trading Days ending on, and including, the second (2nd) Trading Day immediately preceding the first day of such Contingent Interest Period and (ii) in the event that Contingent Interest is payable as a
result of the Downside Trigger, be equal to one half of one percent (0.50%) of the principal amount of such Notes. Contingent Interest shall accrue from the first day of the applicable Contingent Interest Period through, but excluding, the Interest
Payment Date immediately following the end of such Contingent Interest Period, and Contingent Interest shall be payable to Holders in the same manner as regular cash interest. For avoidance of doubt, regular cash interest shall continue to accrue at
the per annum rate of three and three quarters percent (3.75%) on the principal amount of the Notes whether or not Contingent Interest is paid, and Contingent Interest, if any, shall be in addition to such regular cash interest.

 The Company shall determine the daily Contingent Interest Trading Prices of the Notes during each Contingent Interest
Measurement Period during which any Notes are outstanding. Upon determining that the Notes shall begin to accrue Contingent Interest during a Contingent Interest Period, the Company shall, on or before the beginning of such Contingent Interest
Period, notify Holders and the Trustee of the fact that Contingent Interest has become payable and the amount of such Contingent Interest payable per $1,000 principal amount of Notes. 

“Contingent Interest Trading Price” has the same meaning ascribed to “Trading Price,” except that if the
Company cannot reasonably obtain at least one (1) bid for five million dollars ($5,000,000) in principal amount of the Notes from a nationally recognized securities dealer or, in the Company’s reasonable judgment, the bid quotations are
not indicative of the secondary market value of the Notes, then the Contingent Interest Trading Price per $1,000 principal amount of the Notes will be determined by a nationally recognized securities dealer retained by the Company for such purpose.

  
 13 

 Contingent Interest, if any, shall accrue and be payable in the same manner, and on the same
dates, as the stated interest payable on the Notes. 
 2.07. Legal Holidays. If a date on which a payment is to be
made with respect to any Note is not a Business Day, then payment may be made on the next succeeding day that is a Business Day, and no interest shall accrue on that payment for the intervening period. Notwithstanding anything to the contrary in the
Indenture or the Notes, the second sentence of the definition of “Business Day” in Section 1.01 of the Base Indenture shall not apply to the Notes. 
 Article III 
 REDEMPTION 

3.01. Right to Redeem. 
 (a) The Company shall have the right, at the Company’s option, at any time, on a Redemption Date on or before April 1, 2016, to redeem (a “Redemption”) all or, from time to
time, any part of the Notes at a Redemption Price payable in cash equal to the principal amount of the Notes to be redeemed, plus the Coupon Make-Whole Payment as of, and accrued and unpaid interest, if any, to, but excluding, such Redemption Date
if the Daily VWAP is at least one hundred and fifty percent (150%) of the then current Conversion Price for each of at least twenty (20) Trading Days in the thirty (30) consecutive Trading Days ending on, and including, the Trading
Day prior to the mailing of the notice of Redemption pursuant to Section 3.03 of the Base Indenture and Section 3.02 hereof. 
 (b) The Company shall have the right, at the Company’s option, at any time, on a Redemption Date after April 1, 2016, to redeem (also, a “Redemption”) all or, from time to time,
any part of the Notes at a Redemption Price payable in cash equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, such Redemption Date. 

(c) Notwithstanding the foregoing clauses (a) and (b), and anything to the contrary in the Indenture or the Notes, (i) if the
Redemption Date with respect to a Note is after a Regular Record Date for the payment of an installment of interest and on or before the related Interest Payment Date, then accrued and unpaid interest on such Note to, but excluding, such Redemption
Date shall be paid, on such Redemption Date, to the Holder of such Note at the close of business on such Regular Record Date, and the Holder surrendering such Note for Redemption shall not be entitled to any such interest unless such Holder was also
the Holder of record of such Note at the close of business on such Regular Record Date and (ii) in no event shall the Company redeem any Notes at a time when the Company has failed to pay interest on the Notes and such failure to pay is
continuing 
 (d) Notwithstanding anything to the contrary in the Indenture or the Notes, the second sentence of the final
paragraph of Section 3.05 of the Base Indenture shall not apply to the Notes. 
 3.02. Notice of Redemption.
Each notice of Redemption provided pursuant to Section 3.03 of the Base Indenture shall state, in addition to the information required by such Section 3.03 to be included in such notice, (i) that Holders have the right to convert
the Notes called for Redemption; (ii) the Conversion Rate then in effect; (iii) the date on which such right to convert the Notes called for Redemption will begin; and (iv) the date on which such right to convert the Notes called for
Redemption will expire. Notwithstanding anything to the contrary in the Indenture or the Notes, (A) the final paragraph of Section 3.03 of the Base Indenture shall not apply to the Notes; and (B) the number 35 in the second sentence
of Section 3.01 of the Base Indenture shall, for purposes of the Notes, be replaced with the number 30. 

  
 14 

 3.03. Selection and Notice. Notwithstanding anything to the contrary in the
Indenture or the Notes, (i) the first sentence of Section 3.02 of the Base Indenture shall not apply to the Notes; (ii) if less than all of the Notes are to be redeemed, then the Trustee will select the Notes to be redeemed by lot,
pro rata or another method the Trustee considers fair and appropriate; (iii) Notes selected to be redeemed will be redeemed in principal amounts of $2,000 and integral multiples of $1,000 in excess thereof, and no Notes of $2,000 or less in
principal amount will be redeemed in part; and (iv) if a portion of any Note is selected for Redemption and a portion of such Note is converted, then the converted portion will be deemed to be taken from the portion selected for Redemption.

 3.04. Transfers and Exchanges; Miscellaneous. Notwithstanding anything to the contrary in the Indenture or the
Notes, (i) the final paragraph of Section 2.08 of the Base Indenture shall not apply to the Notes; and (ii) the Company shall not be required to (A) issue, register the transfer of, or exchange any Notes during the period of
fifteen (15) days before the mailing of the notice of Redemption; or (B) register the transfer of or exchange any Notes selected for Redemption, in whole or in part, except the unredeemed portion of any Notes being redeemed in part.
Notwithstanding anything to the contrary in the Indenture or the Notes, the phrase “interest shall cease to accrue on the Securities or the portions of Securities called for redemption” in the first (1st) sentence of the second
(2nd) paragraph of Section 3.05 of the Base Indenture shall, for purposes of the Notes, be replaced with the phrase “Securities or the portions of Securities called for redemption shall cease to be outstanding, interest shall cease to
accrue thereon and all rights of the Holders thereof with respect thereto will terminate, other than the right to receive the Redemption Price in accordance with the Indenture”. 

Article IV

 4.01.
Option of Holder to Tender Notes for Repurchase Upon a Fundamental Change. 
 (a) If a Fundamental Change occurs at
any time prior to the Maturity Date, then each Holder of Notes not previously repurchased or redeemed by the Company shall have the right (the “Fundamental Change Repurchase Right”), at such Holder’s option, to require the
Company to repurchase all of such Holder’s Notes (or any portion thereof that is a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof), on a date selected by the Company (the “Fundamental Change Repurchase
Date”), which Fundamental Change Repurchase Date shall be no later than thirty five (35) calendar days, nor earlier than twenty (20) calendar days, after the date the Fundamental Change Repurchase Right Notice is mailed in

unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date; provided, however, that if the Fundamental Change Repurchase Date with respect to a Note is after a Regular Record Date for the payment of an
installment of interest and on or before the related Interest Payment Date, then accrued and unpaid interest on such Note to, but excluding, such Fundamental Change Repurchase Date shall be paid, on such Fundamental Change Repurchase Date, to the
Holder of such Note at the close of business on such Regular Record Date, and the Holder surrendering such Note for repurchase shall not be entitled to any such interest unless such Holder was also the Holder of record of such Note at the close of
business on such Regular Record Date; provided, further, that in no event shall the Company redeem any Notes at a time when the Company has failed to pay interest on the Notes and such failure to pay is continuing. Notwithstanding anything to
the contrary in the Indenture or the Notes, the second sentence of the final paragraph of Section 3.05 of the Base Indenture shall not apply to the Notes. 

  
 15 

 (b) Subject to Section 4.01(c), to exercise the Fundamental Change Repurchase
Right with respect to a Note, the Holder thereof must:

 (C) that such Note shall be repurchased pursuant to the terms and conditions
specified in the Indenture; and 
 (ii) undertake a book-entry transfer or delivery of such Note, together with
necessary endorsements, to the offices of the Paying Agent, which Note so transferred or delivered shall conform in all respects to the description thereof set forth in the related Fundamental Change Repurchase Notice; 

provided, however, that if such Note is held in the form of a Global Security, then such Fundamental Change Repurchase
Notice must comply with appropriate procedures of the Depositary. 
 The satisfaction of the requirements set forth in clauses
(i) and (ii) above with respect to a Note shall be a condition to the receipt by the Holder of such Note of the Fundamental Change Repurchase Price for such Note. 
 (c) A Fundamental Change Repurchase Notice delivered with respect to a Note may be withdrawn by delivering a written notice of withdrawal to the office of the Paying Agent at any time prior to 5:00 p.m.,

 (i) if such Note is certificated,

 (iii) the principal amount, if any, of such Note which remains subject to such original Fundamental Change
Repurchase Notice, which must be $2,000 or an integral multiple of $1,000 in excess thereof; 
 provided, however,
that if such Note is held in the form of a Global Security, then such notice of withdrawal must comply with appropriate procedures of the Depositary. The Paying Agent will promptly return to the Holder thereof any Note with respect to which a
Fundamental Change Repurchase Notice has been withdrawn in accordance with this Section 4.01(c). 
 (d) Any
repurchase of a Note of a Holder by the Company contemplated pursuant to the provisions of this Article IV shall be consummated by the delivery of the consideration to be received by such Holder. 

  
 16 

 (e) The Paying Agent shall promptly notify the Company of the receipt by it of any
Fundamental Change Repurchase Notice or written withdrawal thereof. 
 4.02. Announcement of Fundamental Change Repurchase
Right. On or before the twentieth (20th) calendar day after the occurrence of a Fundamental Change, the Company shall mail a written notice (a “Fundamental Change Repurchase Right Notice”) of the Fundamental Change
by first class mail to the Trustee, the Paying Agent, the Conversion Agent and each Holder (and to beneficial owners as required by applicable law), which notice shall include a form of Fundamental Change Repurchase Notice and shall state:

 (a) briefly, the events causing a Fundamental Change and the date of such Fundamental Change; 

(b) the date by which the Fundamental Change Repurchase Notice pursuant to this Article IV must be delivered to the Paying Agent
in order for a Holder to exercise the Fundamental Change Repurchase Right;

 (f) the
Conversion Rate in effect on the date of such Fundamental Change Repurchase Right Notice and any adjustments thereto; 
 (g)
that the Notes as to which a Fundamental Change Repurchase Notice has been given may be converted if they are otherwise convertible pursuant to the Indenture only if the Fundamental Change Repurchase Notice has been withdrawn in accordance with the
Indenture; 
 (h) that the Notes must be surrendered (by book-entry transfer or delivery) to the Paying Agent to collect
payment; 
 (i) that the Fundamental Change Repurchase Price for any Note as to which a Fundamental Change Repurchase Notice has
been duly given and not withdrawn will be paid promptly following the later of the Fundamental Change Repurchase Date and the time of surrender of such Note as described in clause (h) above; 

(j) briefly, the procedures the Holder must follow to exercise its Fundamental Change Repurchase Right; 

(k) briefly, the conversion rights of the Notes; 
 (l) the procedures for withdrawing a Fundamental Change Repurchase Notice;

 (n) the CUSIP number(s) of the Notes; and 

  
 17 

 (o) any other information the Company wishes to provide. 

For avoidance of doubt, the Company’s obligation to provide such Fundamental Change Repurchase Right Notice shall be in addition to
the Company’s obligations to provide any notice pursuant to Section 12.01(c) or Section 12.03(f). 

4.03. Effect of Fundamental Change Repurchase Notice. Upon receipt by the Paying Agent of the Fundamental Change Repurchase
Notice with respect to a Note, the Holder thereof shall (unless such Fundamental Change Repurchase Notice is withdrawn in accordance with Section 4.01(c)) thereafter be entitled to receive solely the Fundamental Change Repurchase Price
with respect to such Note. If the requirements set forth in clauses (i) and (ii) of Section 4.01(b) have been satisfied, then, notwithstanding anything to the contrary in the Indenture or the Notes, such Fundamental Change
Repurchase Price shall be paid to such Holder, subject to the receipt of funds by the Paying Agent, promptly following the later of (x) the Fundamental Change Repurchase Date with respect to such Note and (y) the time of book-entry
transfer or delivery of such Notes in accordance with clause (ii) of Section 4.01(b). Notes in respect of which a Fundamental Change Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article
XII on or after the date of the delivery of such Fundamental Change Repurchase Notice unless such Fundamental Change Repurchase Notice has first been validly withdrawn in accordance with Section 4.01(c). 

If the Paying Agent holds on the Business Day immediately following the Fundamental Change Repurchase Date cash sufficient to pay the
Fundamental Change Repurchase Price of the Notes that Holders have elected to require the Company to purchase, then, as of the Fundamental Change Repurchase Date (x) such Notes will cease to be outstanding and interest will cease to accrue,
whether or not book-entry transfer of such Notes has been made or such Notes have been delivered to the Paying Agent, as the case may be, and (y) all other rights of the Holders of such Notes will terminate, other than the right to receive the
Fundamental Change Repurchase Price upon delivery or transfer of such Notes. 
 4.04. Deposit of Fundamental Change
Repurchase Price. Prior to 12:00 noon, New York City time, on the Business Day immediately following the Fundamental Change Repurchase Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or its
Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust) an amount of cash (in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate Fundamental Change
Repurchase Price of all the Notes or portions thereof which are to be repurchased pursuant to this Article IV. 

4.05. Notes Repurchased in Part. Any certificated Note which is to be repurchased pursuant to this Article IV only
in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or Notes of any authorized denomination as
requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered which is not so repurchased. Provisions of the Indenture that apply to the purchase of all of a Note
also apply to the purchase of a portion of such Note. 
 4.06. Repayment to the Company. The Trustee and the
Paying Agent shall return to the Company any cash that remains unclaimed as provided in Section 8.06 of the Base Indenture (subject to the provisions of Section 7.01(f) of the Base Indenture) and that is held by them for the payment of the

  
 18 

 
Fundamental Change Repurchase Price; provided, however, that to the extent that the aggregate amount of cash deposited by the Company pursuant to this Article IV exceeds the
aggregate Fundamental Change Repurchase Price of the Notes or portions thereof which the Company is obligated to repurchase pursuant to this Article IV, then, unless otherwise agreed in writing with the Company, promptly after the Business
Day following the Fundamental Change Repurchase Date, the Trustee shall return any such excess to the Company (subject to the provisions of Section 7.01(f) of the Base Indenture). 

4.07. Covenant to Comply With Securities Laws Upon Purchase of Notes. In connection with any repurchase of Notes pursuant
to this Article IV, the Company will, to the extent applicable, (i) comply with the provisions of Rule 13e-4 under the Exchange Act and any other tender offer rules under the Exchange Act that may be applicable at the time of the offer
by the Company to repurchase the Notes pursuant to this Article IV; (ii) file a Schedule TO or any other schedule required in connection with any offer by the Company to repurchase the Notes; and (iii) comply with all other federal

Opinion of Counsel to the effect that the transaction(s) and any such supplemental indenture will comply with the requirements of the foregoing clauses of this Section 5.01.

that comply with, Section 5.01 where the Company is not the continuing corporation, the successor person formed or remaining shall succeed, and be substituted for, and may exercise every right and power of, the Company, and the Company
shall be discharged from its obligations, under the Notes and the Indenture.

 Article IX

 SUBSIDIARY GUARANTEES 

Notwithstanding anything to the contrary in the Indenture or the Notes, Article 12 of the Base Indenture shall, for purposes of the
Notes, be deemed to be replaced with this Article IX and the Base Indenture shall, for purposes of the Notes, be read mutatis mutandis. 
 9.01. Subsidiary Guarantees. 
 (a) The Notes shall be guaranteed by
each of the Guarantors (each such guarantee, a “Subsidiary Guarantee”) in accordance with the provisions of this Article IX. 
 (b) Subject to this Article IX, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of the Notes or the obligations of the Company under the Indenture or
the Notes: (i) that the principal of, and interest on, the Notes will be promptly paid in full when due, whether at the Maturity Date, the Redemption Date, the Fundamental Change Repurchase Date or other due date, and interest on the overdue
principal of and interest on the Notes, if any, if lawful, and that all other obligations of the Company to the Holders or the Trustee hereunder will be promptly paid in full or performed, all in accordance with the terms of the Indenture; and
(ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at
the Maturity Date, the Redemption Date, the Fundamental Change Repurchase Date or other due date. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and
severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 (c) Subject to this Article IX, the Guarantors hereby, jointly and severally, agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of 

  
 24 

 
the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions of the Indenture or of the Notes, the
recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment,
demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Subsidiary
Guarantee shall not be discharged except by complete performance of the obligations contained in the Indenture and the Notes. 

(d) If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Guarantor or any custodian, trustee,
liquidator or other similar official acting in relation to either the Company or the Guarantors any amount paid by any of the foregoing to such Holder or the Trustee, then each Subsidiary Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. 
 (e) Each Guarantor agrees that it shall not be entitled to any right of subrogation in
relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on
the other hand, (i) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of the Subsidiary Guarantees, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby; and (ii) in the event of any declaration of acceleration of such obligations as provided in Article VI, such obligations (whether or not due and payable) shall forthwith
become due and payable by the Guarantors for the purpose of the Subsidiary Guarantees. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the
Holders under the Subsidiary Guarantees. 
 Notwithstanding anything to the contrary in the Indenture or the Notes, references
in the Indenture or the Notes to Section 12.02 of the Base Indenture shall, for purposes of the Notes, be read as references to this Section 9.01. 
 9.02. Subordination of Subsidiary Guarantees. The obligations of each Guarantor under the Indenture and the Notes shall be junior and subordinated to the Senior Debt of such Guarantor on the
same basis as the Notes are junior and subordinated to Senior Debt of the Company. For the purposes of the foregoing sentence, the Trustee and Holders shall have the right to receive or retain payments by any of the Guarantors only at such times as
they may receive or retain payments in respect of the Notes pursuant to the Indenture, including, without limitation, Article 11 of the Base Indenture. 
 Notwithstanding anything to the contrary in the Indenture or the Notes, references in the Indenture or the Notes to Section 12.03 of the Base Indenture shall, for purposes of the Notes, be read as
references to this Section 9.02. 
 9.03. Guarantors May Consolidate, Etc., on Certain Terms. Each
Guarantor agrees that such Guarantor may not sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person), another Person, other than the
Company or another Guarantor, unless: 
 (a) immediately after giving effect to such transaction, no Default or Event of Default
exists; and 

  
 25 

 (b) subject to Section 9.04 hereof, the Person acquiring the assets in any such
sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the obligations of such Guarantor under the Indenture and its Subsidiary Guarantee pursuant to a supplemental indenture satisfactory to the
Trustee. 
 Subject to Section 9.04, if there shall occur any such sale, disposition, consolidation or merger with
respect to a Guarantor, then, upon the assumption by the successor Person, by supplemental indenture executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee of such Guarantor and the due and
punctual performance of all of the covenants and conditions of the Indenture to be performed by such Guarantor, such successor Person shall succeed to and be substituted for such Guarantor with the same effect as if such successor Person had been
named in the Indenture as a Guarantor. Each Subsidiary Guarantee so issued shall in all respects have the same legal rank and benefit under the Indenture and the Notes as the Subsidiary Guarantees theretofore and thereafter issued in accordance with
the terms of the Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution hereof. 

Except as provided in Article V, and notwithstanding clauses (a) and (b) above, nothing contained in the Indenture or in
any of the Notes shall prevent any sale or other disposition of all or substantially all of the assets of a Guarantor to the Company or another Guarantor or prevent any consolidation or merger of a Guarantor with or into the Company or another
Guarantor. 
 9.04. Releases. The Subsidiary Guarantee of a Guarantor will be released, and any Person acquiring
assets (including by way of merger or consolidation) or Capital Stock of a Guarantor shall not be required to assume the obligations of such Guarantor: 
 (a) in connection with any sale or other disposition of all or substantially all of the assets of such Guarantor (including by way of merger or consolidation) to a Person that is not (either before or
after giving effect to such transaction) the Company or a Subsidiary of the Company; 
 (b) in connection with any sale of a
majority of the Capital Stock of such Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Subsidiary of the Company; 
 (c) if the Company designates such Guarantor to be an Excluded Subsidiary in accordance with the requirements hereof (including, without limitation, the definition of Excluded Subsidiary); 

(d) if such Guarantor is otherwise no longer obligated to provide a Subsidiary Guarantee pursuant hereto; 

(e) if such Guarantor’s guarantee of any obligations under the Credit Agreement, or, if the Credit Agreement is no longer
outstanding, any other Indebtedness of the Company, is fully and unconditionally released, except that such Guarantor shall subsequently be required to become a Guarantor by executing a supplemental indenture and providing the Trustee with an
Officers’ Certificate and Opinion of Counsel at such time as it guarantees any obligations under the Credit Agreement, or, if the Credit Agreement is no longer outstanding, any other Indebtedness of the Company; or 

(f) if the Company’s obligations under the Indenture and the Notes are discharged in accordance with the terms thereof. 

  
 26 

 Notwithstanding anything to the contrary in the Indenture or the Notes, references in the
Indenture or the Notes to Section 12.05 of the Base Indenture shall, for purposes of the Notes, be read as references to this Section 9.04. 
 9.05. Fraudulent Conveyances. Each Guarantor, and, by its acceptance of any Note, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of
such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any
Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor under its Subsidiary Guarantee shall be limited to the maximum amount as will,
after giving effect to all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other
Guarantor in respect of the obligations of such other Guarantor under its Subsidiary Guarantee, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance. 

Notwithstanding anything to the contrary in the Indenture or the Notes, references in the Indenture or the Notes to Section 12.04 of
the Base Indenture shall, for purposes of the Notes, be read as references to this Section 9.05. 
 9.06.
Additional Subsidiary Guarantees. If, after the date hereof, a Person who was not theretofore a Guarantor becomes a Guarantor, then such Person shall, as promptly as possible after the end of the fiscal quarter in which such Person
becomes a Guarantor, execute a supplemental indenture, substantially in the form set forth in Exhibit B, and deliver an opinion of counsel, in each case in form and substance reasonably satisfactory to the Trustee.

(a) either (i) all outstanding Notes (other than Notes replaced pursuant to Section 2.09 of the Base Indenture) have been delivered to the Trustee for cancellation; or (ii) all outstanding Notes have become due and payable at
their scheduled maturity or upon Redemption or the exercise of the Fundamental Change Repurchase Right or otherwise, or upon conversion of the Notes, and, in either case, the Company irrevocably deposits, prior to the applicable due date, with the
Trustee, the Paying Agent (if the Paying Agent is not the Company or any of its Affiliates) or, if applicable, the Conversion Agent (if the Conversion Agent is not the Company or any of its Affiliates), cash, and, if applicable as herein provided
and in accordance herewith, such other consideration, sufficient to pay all amounts due and owing on all outstanding Notes (other than Notes replaced pursuant to Section 2.09 of the Base Indenture) on the Maturity Date, Redemption Date,

by the Company; and (c) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for herein relating
to the satisfaction and discharge of the Indenture have been complied with; provided, however, that Sections 2.02, 2.04, 2.06, 2.07, 2.08, 2.09, 2.10, 3.04, 4.01, 4.02 and 4.06, and Article 7, of the Base Indenture, and
Section 12.02(j), Section 3.04, Article IV, Article X and Article XII hereof, shall, with respect to the Notes, survive any such discharge until such time as the Notes have been paid in full. 

10.03. Application of Trust Money. The Trustee shall hold in trust all money and other consideration deposited with it

money or other consideration held by them for the payment of the principal of, premium, if any, or any accrued and unpaid interest on, the Notes that remains unclaimed for two (2) years; provided, however, that the Trustee, the
Paying Agent or the Conversion Agent, before being required to make any such repayment, may, at the expense of the Company, cause to be published once in a newspaper of general circulation in the City of New York or cause to be mailed to each
Holder, notice stating that such money remains unclaimed and that, after a date specified therein, which shall not be less than thirty (30) days from the date of such publication or mailing, any unclaimed balance of such money then remaining
will be repaid to the Company. After payment to the Company, Holders entitled to the money must look to the Company for payment as general creditors, subject to applicable law, and all liability of the Trustee, the Paying Agent and the Conversion
Agent with respect to such money and payment shall, subject to applicable law, cease.

any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company under the Indenture with respect to the Notes, and the obligations of the Company under the Notes, shall be revived
and reinstated as though no deposit had occurred pursuant to Section 10.02 and Section 10.03; provided, however, that if the Company has made any payment of amounts due with respect to any Notes because of the
reinstatement of its obligations, then the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee, Paying Agent or Conversion Agent. 

Article XI 

SUBORDINATION

the Notes, for purposes of the Notes:

Article XII 
 CONVERSION OF THE NOTES 
 12.01. Conversion Privilege. 
 (a) Subject to and upon compliance
with this Article XII, a Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the principal amount of the portion to be converted is $2,000 or an integral multiple of $1,000 in excess thereof)
of such Note into cash and, if applicable, shares of Common Stock in accordance with this Article XII. 
 (b)
Notwithstanding anything to the contrary in the Indenture or the Notes, the Notes shall not be convertible pursuant to this Article XII except as follows: 

(i) prior to April 1, 2040, the Notes may be converted on any date during any calendar quarter beginning after
June 30, 2012 (and only during such calendar quarter), if the Closing Sale Price per share of Common Stock was more than one hundred and thirty percent (130%) of the then current Conversion Price for at least twenty (20) Trading Days
in the period of thirty (30) consecutive Trading Days ending on, and including, the last Trading Day of the previous calendar quarter; 
 (ii) the Notes may be converted at any time on or after April 1, 2040; 
 (iii) a Note that is called for Redemption may be converted at any time on or after the date the notice of Redemption is mailed pursuant to Section 3.03 of the Base Indenture and
Section 3.02 hereof until the close of business on the Business Day prior to the applicable Redemption Date; 
 (iv) if the Company distributes, to all holders of Common Stock, rights or warrants (other than pursuant to a rights plan) entitling them to purchase, for a period expiring not more than sixty
(60) calendar days following the record date for such distribution, shares of Common Stock at a price per share less than the average Closing Sale Price per share of Common Stock for 

  
 29 

 
the ten (10) consecutive Trading Days immediately preceding the announcement date for such distribution, then the Notes may be converted at any time from and including the date the Company
provides notice of such distribution pursuant to Section 12.01(c) until the earlier of (A) 5:00 p.m., New York City time, on the Business Day preceding the Ex-Date for such distribution and (B) any announcement by the Company
that such distribution will not take place; 
 (v) if the Company distributes, to all holders of Common Stock,
cash or other assets, debt securities or rights to purchase the Company’s securities (other than pursuant to a rights plan), which distribution has a value per share of Common Stock exceeding ten percent (10%) of the Closing Sale Price per
share of Common Stock on the Trading Day preceding the announcement date for such distribution, then the Notes may be converted at any time from and including the date the Company provides notice of such distribution pursuant to
Section 12.01(c) until the earlier of (A) 5:00 p.m., New York City time, on the Business Day preceding the Ex-Date for such distribution and (B) any announcement by the Company that such distribution will not take place;

 (vi) if: 
 (A) the Company is a party to a consolidation, merger, binding share exchange or sale or conveyance of all or substantially all of the Company’s property and assets; 

(B) such consolidation, merger, binding share exchange, sale or conveyance does not constitute a Fundamental Change; and

 (C) pursuant to such consolidation, merger, binding share exchange, sale or conveyance, the Common Stock would
be converted into cash, securities or other property, 
 then the Notes may be converted at any time during the
period that begins fifteen (15) calendar days prior to the date announced by the Company as the anticipated effective date of such consolidation, merger, binding share exchange, sale or conveyance and that ends on, and includes, the date that
is fifteen (15) calendar days after the date that is the actual effective date of such consolidation, merger, binding share exchange, sale or conveyance; 
 (vii) if a transaction described under clauses (1), (3) or (4) of the definition of Fundamental Change in Section 1.01 occurs, then the Notes may be converted at any time during the
period that begins on the Business Day following the effective date of such Fundamental Change and that ends at 5:00 p.m., New York City time, on the Business Day preceding the Fundamental Change Repurchase Date relating to such Fundamental Change;
and 
 (viii) the Notes may be converted during the five (5) consecutive Business Day period following any
five (5) consecutive Trading Day period (such five (5) consecutive Trading Day period, the “Note Measurement Period”), if, on each Trading Day during such Note Measurement Period, the Trading Price of the Notes (expressed
as an amount per $1,000 principal amount of Notes) on such Trading Day, as determined following a request by a Holder in accordance with Section 12.01(d), was less than ninety eight percent (98%) of the product of (A) the
Closing Sale Price per share of Common Stock on such Trading Day and (B) the Conversion Rate in effect on such Trading Day (the condition set forth in this clause (viii) is herein referred to as the “Trading Price
Condition”); 

  
 30 

 provided, however, that (x) in no event shall the Notes be convertible at or after the
close of business on the Business Day immediately preceding the Maturity Date; (y) in no event shall the Notes that have been previously redeemed, repurchased or converted be thereafter converted; and (z) a Note in respect of which a
Fundamental Change Repurchase Notice has been given by the Holder thereof may not be converted on or after the date of the delivery of such Fundamental Change Repurchase Notice unless such Fundamental Change Repurchase Notice has first been validly
withdrawn in accordance with Section 4.01(c), and, unless such Fundamental Change Repurchase Notice has been so validly withdrawn or the Company defaults in the payment of the Fundamental Change Repurchase Price, the conversion right
with respect to such Note will expire at 5:00 p.m., New York City time, on the Business Day preceding the related Fundamental Change Repurchase Date. 
 (c) At least thirty (30) calendar days prior to the Ex-Date of a distribution by the Company referred to in Section 12.01(b)(iv) or Section 12.01(b)(v), the Company will
provide notice to Holders of such distribution. If a transaction described under clauses (1), (3) or (4) of the definition of Fundamental Change in Section 1.01 occurs, then the Company will notify Holders of the anticipated
effective date of such Fundamental Change at least ten (10) calendar days prior to such date. 
 (d) The Company shall have
no obligation to determine the Trading Price of the Notes unless a Holder requests in writing that the Company do so, but if a Holder provides such a written request to the Company, then the Company will determine the Trading Price of the Notes on
the Trading Day immediately following the date the Company receives such written request and on each subsequent Trading Day until the Trading Price Condition is no longer satisfied. 

12.02. Conversion Procedure; Settlement Upon Conversion; Fractional Shares. 

(a) To convert a Note, the Holder thereof must (i) complete, manually sign and deliver to the Conversion Agent the conversion notice
on the back of such Note (or a facsimile of such conversion notice); (ii) surrender such Note (together with appropriate endorsements and transfer documents) to the Conversion Agent; and (iii) if applicable, deliver to the Conversion Agent
any funds, taxes or duties required to be delivered pursuant to Section 12.02(f) or Section 12.02(h); provided, however, that if such Note is held in the form of a Global Security, then (x) in lieu of
manually signing and delivering such conversion notice (or facsimile thereof), such Holder must deliver to Depositary the appropriate instruction form for conversion pursuant to the Depositary’s conversion program; and (y) such surrender
of such Note pursuant to clause (ii) shall be made by book-entry transfer through the Depositary. Subject to Section 12.02(e), such Note will be deemed to have been converted as of 5:00 p.m., New York City time, on the date (such
date, the “Conversion Date”) that all the conditions of the immediately preceding sentence have been satisfied. 
 (b) If any Note is surrendered for partial conversion, then the Company will execute and the Trustee will authenticate and deliver to or upon the written order of the Holder of such Note, without charge
to such Holder (subject to Section 12.02(h)), a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of such surrendered Note. 

(c) Subject to Section 12.04, upon conversion of a Note in accordance with this Article XII, the Company will deliver,
on (subject to Section 12.03(c) and Section 12.03(e)) the fifth (5th) Business Day immediately following the last day of the Cash Settlement Averaging Period applicable to such conversion, to the Holder of such Note,
consideration, per $1,000 principal amount of such Note that is subject to such conversion, consisting of (i) cash in an amount equal to the sum of the Daily Cash Settlement Amounts for each Trading Day in such Cash Settlement Averaging Period
(the amount of cash deliverable upon such conversion pursuant to this clause (i), subject to the provisos to this sentence, the 

  
 31 

 
“Aggregate Cash Settlement Amount”); and (ii) a number of shares of Common Stock, if any, equal to the sum of the Daily Net Shares for each Trading Day in such Cash
Settlement Averaging Period (the number of shares of Common Stock deliverable upon such conversion pursuant to this clause (ii), subject to the provisos to this sentence, the “Aggregate Net Shares”); provided, however,
that the Company will not issue fractional shares of Common Stock and will instead deliver cash (in addition to any other consideration payable upon such conversion) in an amount equal to the value of such fraction computed on the basis of the
Closing Sale Price per share of Common Stock on the last Trading Day of such Cash Settlement Averaging Period; provided, further, that if, and only if, delivery of the Aggregate Net Shares upon settlement of such conversion would not
be permissible under the listing standards of the New York Stock Exchange without the Company first having obtained stockholder approval in accordance with such listing standards, and the Company has not theretofore obtained such stockholder
approval, then, with respect to such conversion, the Company may, on any one or more Trading Days during such Cash Settlement Averaging Period, reduce the number of Daily Net Shares applicable to such Trading Day(s) to the extent, and only to the
extent, necessary so that the number of Aggregate Net Shares required to be delivered upon settlement of such conversion pursuant to this Section 12.02(c) does not exceed the maximum amount permitted to be delivered pursuant to such
listing standards, provided that, for each one (1) share (or fraction thereof) of Common Stock the Company deducts from the Daily Net Shares of a Trading Day pursuant to this proviso, the Company shall increase the Daily Cash Settlement
Amount for such Trading Day by an amount equal to the Daily VWAP on such Trading Day (or, in the case a fraction of a share was so deducted, an amount equal to the product of such fraction and the Daily VWAP on such Trading Day). In addition, in the
event that a Note is converted in connection with a Redemption pursuant to Section 3.01(a) hereof, the Company will deliver to the Holder of such Note, together with any consideration delivered in accordance with the immediately
preceding sentence, cash in an amount equal to the Coupon Make-Whole Payment. A conversion shall be deemed to be “in connection with” a Redemption pursuant to Section 3.01(a) hereof if the Notes are converted at any time on or
after the date the related notice of Redemption is mailed pursuant to Section 3.03 of the Base Indenture and Section 3.02 hereof until the close of business on the Business Day prior to the applicable Redemption Date. 

(d) If a Holder converts more than one Note at the same time, then the number of full shares of Common Stock issuable upon such
conversion, if any, shall be based on the total principal amount of all such Notes converted at the same time by such Holder. 

(e) At and after the close of business on the last Trading Day of the Cash Settlement Averaging Period applicable to a Note to be
converted, the Person in whose name any certificate (or electronic entry or other notation) representing Aggregate Net Shares, if any, is to be registered shall be treated as a stockholder of record of such Aggregate Net Shares. On and after the
Conversion Date of a Note to be converted, all rights of the Holder of such Note will terminate, other than the right to receive the consideration deliverable upon such conversion in accordance with the Indenture. 

(f) If the Conversion Date of a Note to be converted occurs after a Regular Record Date but prior to the corresponding Interest Payment
Date, then, notwithstanding such conversion and notwithstanding anything to the contrary in the Indenture or the Notes, the interest payable with respect to such Note on such Interest Payment Date shall be paid on such Interest Payment Date to the
Holder of such Note at the close of business on such Regular Record Date; provided, however, that such Note, when surrendered for conversion, must be accompanied by cash payment to the Conversion Agent on behalf of the Company of an amount
equal to the interest payable on such Interest Payment Date on such Note, except that no such payment shall be required if either (i) such Note was called for Redemption and the related Redemption Date is after such Regular Record Date and on
or before such Interest Payment Date; (ii) the Company has designated a Fundamental Change Repurchase Date pursuant to Section 4.02(c) that is after such Regular Record Date and on or before such Interest Payment Date; or
(iii) such Conversion 

  
 32 

 
Date occurs after the Regular Record Date immediately preceding the Maturity Date; provided, further, that in no event shall such Holder be required to pay any overdue interest
pursuant to this Section 12.02(f). Except as provided in this Section 12.02(f), upon conversion of a Note, the Holder of such Note will not be entitled to receive any separate cash payment of accrued and unpaid interest on
such Note, and unpaid interest that has accrued to the Conversion Date of such Note shall be deemed to be paid in full with the Conversion Consideration delivered upon such conversion rather than cancelled, extinguished or forfeited. 

(g) From and after the Conversion Date of a Note, (i) such Note shall cease to be outstanding and, except as provided in
Section 12.02(f), interest will cease to accrue on such Note; and (ii) all rights of the Holders of such Notes with respect thereto will terminate, other than the right to receive the Conversion Consideration therefor in accordance
with the Indenture, in each case unless the Company defaults in delivering such Conversion Consideration in accordance with the Indenture. 
 (h) The Company shall pay any documentary, stamp or similar issue or transfer tax or duty due on the issue, if any, of shares of Common Stock upon any conversion of any Note; provided,
however, that the Holder of such Note shall pay any such tax or duty which is due because such shares are issued in a name other than such Holder’s name. The Conversion Agent may refuse to deliver a certificate representing the shares of
Common Stock to be issued in a name other than such Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax or duty which will be due because such shares are to be issued in a name other than such Holder’s name.
Nothing herein shall preclude any tax withholding required by law or regulation. 
 (i) If the Conversion Rate is adjusted
pursuant to this Article XII, then the Company will (i) issue a press release through Business Wire setting forth the new Conversion Rate and its effective date and make such information available on its website or through another public
medium as the Company may use at that time; and (ii) provide the Trustee with an Officers’ Certificate setting forth the new Conversion Rate and its effective date. 
 (j) The Company will maintain an office or agency where Notes may be presented for conversion (the “Conversion Agent”). The Company may appoint or change one or more co-Conversion Agents
without notice and may act in any such capacity on its own behalf. The term “Conversion Agent” includes any additional co-Conversion Agent. The Company hereby elects the Trustee as the initial Conversion Agent. 

12.03. Adjustments to the Conversion Rate. The Conversion Rate shall be adjusted from time to time as follows: 

(a) If the Company issues shares of Common Stock as a dividend or distribution on shares of Common Stock, or if the Company effects a
share split or share combination of the Common Stock, then the Conversion Rate will be adjusted based on the following formula: 
  

			
	

		
	where,	 	
		
	CR1 =	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Date for such dividend or distribution or the effective date of such share split or combination,
as the case may be;

  

  
 33 

	 	CR0 =	 the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding such Ex-Date or effective date, as applicable;

  

	 	OS0 =	 the number of shares of Common Stock outstanding at 5:00 p.m., New York City time, on the Trading Day immediately preceding such Ex-Date or effective
date, as applicable; and 

  

	 	OS1 =	 the number of shares of Common Stock that would be outstanding immediately after, and solely as a result of, such dividend, distribution, share split
or share combination. 

 (b) Subject to Section 12.03(i), if the Company distributes to all or
substantially all holders of Common Stock any rights or warrants entitling them to purchase, for a period of sixty (60) calendar days following the record date for such distribution, shares of Common Stock at a price per share less than the
average Closing Sale Price per share of Common Stock for the ten (10) Trading Days immediately preceding the declaration date for such distribution, then the Conversion Rate will be increased based on the following formula; 

 
 

 
 where, 
  

	 	CR1 =	 the Conversion Rate in effect immediately prior to the open of business on the Ex-Date for such distribution; 

 

	 	CR0 =	 the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding such Ex-Date; 

 

	 	OS0 =	 the number of shares of Common Stock outstanding at 5:00 p.m., New York City time, on the Trading Day immediately preceding such Ex-Date;

  

	 	X     =	the total number of shares of Common Stock issuable pursuant to such rights or warrants; and 

 

	 	Y     =	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the average of the Last Reported Sale
Prices per share of Common Stock over the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding such Ex-Date. 

For the purposes of this Section 12.03(b), in determining whether any rights or warrants entitle the holders thereof to
subscribe for or purchase shares of Common Stock at less than the average Closing Sale Price per share of Common Stock for the ten (10) Trading Days immediately preceding the declaration date for such distribution, and in determining the
aggregate price payable to exercise such rights or warrants, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount payable upon exercise thereof, with the value of such consideration,
if other than cash, as shall be determined in good faith by the Board of Directors. 

  
 34 

 (c) Subject to Section 12.03(i), if the Company distribute shares of the
Company’s Capital Stock, evidences of the Company’s indebtedness or other assets or property of the Company to all or substantially all holders of Common Stock, excluding: 

(i) dividends or distributions as to which adjustment is required to be effected pursuant to Section 12.03(a)
or Section 12.03(b); 
 (ii) the initial distribution of rights issued pursuant to a stockholder
rights plan, provided that such rights plan provides for the issuance of such rights with respect to Common Stock issued upon conversion of the Notes; 
 (iii) dividends or distributions paid exclusively in cash; and 

(iv) spin-offs described below in the third paragraph of this Section 12.03(c), 

then the Conversion Rate will be adjusted based on the following formula: 

 
 

 
 where, 
  

	 	CR1   =	 the Conversion Rate in effect immediately prior to the open of business on the Ex-Date for such distribution; 

 

	 	CR0   =	 the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding such Ex-Date; 

 

	 	SP0    =	 the average of the Last Reported Sale Prices per share of Common Stock over the ten (10) consecutive Trading Day period ending on, and including,
the Trading Day immediately preceding such Ex-Date; and 

  

	 	FMV =	the fair market value (as determined by the Board of Directors) of the shares of Capital Stock, evidences of indebtedness, assets or property distributed with respect
to each outstanding share of Common Stock as of the open of business on such Ex-Date. 

 If
the Board of Directors determines the FMV by reference to the actual or when-issued trading market for any securities, then, in doing so, it must consider the prices in such market over the same period used in computing SP0. Notwithstanding the foregoing, if FMV is equal to or greater than
SP0, then, in lieu of the foregoing adjustment, adequate
provision shall be made so that each Holder shall receive, on the date on which such Capital Stock, evidences of Indebtedness, assets or property are distributed to holders of Common Stock, for each $1,000 principal amount of Notes, the amount of
such Capital Stock, evidences of Indebtedness, assets or property that a person who was a holder of record, on the record date for such distribution, of a number of shares of Common Stock equal to the Conversion Rate in effect on such Ex-Date would
have been entitled to receive pursuant to such distribution. 
 With respect to an adjustment pursuant to this
Section 12.03(c) where there has been a payment of a dividend or other distribution on Common Stock in shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary, or other business unit, of
the Company, which shares 

  
 35 

 
or equity interest is listed on a national or regional securities exchange (a “Spin-Off”), the Conversion Rate will be increased based on the following formula: 

 
 

 
 where, 
  

	 	CR1     =	 the Conversion Rate in effect immediately prior to the open of business on the Ex-Date for such Spin-Off; 

 

	 	CR0     =	 the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding such Ex-Date; 

 

	 	FMV0  =	 the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one
(1) share of Common Stock over the first ten (10) consecutive Trading Day period immediately following, and including, the third (3rd) Trading Day after such Ex-Date (such period, the “Valuation Period”); and

  

	 	MP0     =	 the average of the Last Reported Sale Prices per share of Common Stock over the Valuation Period. 

The adjustment to the Conversion Rate pursuant to the immediately preceding formula will be made immediately after the open of business
on the day after the last day of the applicable Valuation Period, but will be given effect immediately prior to the open of business on the Ex-Date for the applicable Spin-Off. Notwithstanding anything to the contrary in the Indenture or the Notes,
if the final Trading Day of the Cash Settlement Averaging Period applicable to the conversion of any Note occurs on or after the Ex-Date for the Spin-Off and on or before the last Trading Day of the applicable Valuation Period, then the Company
shall deliver the Conversion Consideration for such conversion on the third (3rd) Business Day immediately following the last Trading Day of such Valuation Period. 
 (d) If the Company pays any cash dividends or distributions paid exclusively in cash to all or substantially all holders of Common Stock (other than dividends or distributions made in connection with the
Company’s liquidation, dissolution or winding-up or upon a Conversion Right Adjustment Event), then the Conversion Rate will be increased based on the following formula: 

 
 

 
 where, 
  

	 	CR1 =	 the Conversion Rate in effect immediately prior to the open of business on the Ex-Date for such dividend or distribution; 

 

	 	CR0 =	 the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding such Ex-Date; 

  
 36 

	 	SP0   =	 the average of the Last Reported Sale Prices per share of Common Stock over the ten (10) consecutive Trading Day period ending on, and including,
the Trading Day immediately preceding such Ex-Date; 

  

	 	DTA =	the Dividend Threshold Amount; and 

  

	 	C       =	the amount in cash per share the Company distributes to holders of Common Stock pursuant to such dividend or distribution; 

provided, however, that if C is equal to or greater than SP0, then, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to
receive, on the date on which such cash dividend or distribution is distributed to holders of Common Stock and upon the same terms as such holders, for each $1,000 principal amount of Notes, the amount of cash a person who was a holder of record, on
the record date for such dividend or distribution, of a number of shares of Common Stock equal to the Conversion Rate in effect on such Ex-Date would have been entitled to receive pursuant to such dividend or distribution. 

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for Common Stock, where the
cash and value (as determined by the Board of Directors) of any other consideration included in the payment per share of Common Stock pursuant to such tender offer or exchange offer exceeds the Closing Sale Price per share of Common Stock on the
Trading Day next succeeding the last date (such last date, the “Expiration Date”) on which tenders or exchanges may be made pursuant to such tender offer or exchange offer, then the Conversion Rate will be increased based on the
following formula: 
  
 

 
 where, 
  

	 	CR1 =	 the Conversion Rate in effect immediately prior to the open of business on the Trading Day immediately following the Expiration Date;

  

	 	CR0 =	 the conversion rate in effect at 5:00 p.m., New York City time, on the Expiration Date; 

 

	 	AC  =	the aggregate of the cash and value of all other consideration (as determined by the Board of Directors) paid or payable for all shares of Common Stock purchased in
such tender offer or exchange offer; 

  

	 	SP1  =	 the average of the Last Reported Sale Prices per share of Common Stock over the ten (10) consecutive Trading Day period (the “Averaging
Period”) commencing on, and including, the Trading Day next succeeding the Expiration Date; 

  

	 	OS1 =	 the number of shares of Common Stock outstanding immediately after the close of business on the Expiration Date (excluding shares validly tendered and
accepted for payment pursuant to such tender offer or exchange offer); and 

  

	 	OS0 =	 the number of shares of Common Stock outstanding immediately prior to the Expiration Date (prior to giving effect to such tender offer or exchange
offer). 

  
 37 

 The adjustment to the Conversion Rate pursuant to the immediately preceding formula will be
made immediately prior to the open of business on the day after the last day of the applicable Averaging Period, but will be given effect immediately prior to the open of business on the Trading Day immediately following the Expiration Date.
Notwithstanding anything to the contrary in the Indenture or the Notes, (i) if the final Trading Day of the Cash Settlement Averaging Period applicable to the conversion of any Note occurs on or after the Trading Day immediately following the
Expiration Date and on or before the last Trading Day of the applicable Averaging Period, then the Company shall deliver the Conversion Consideration for such conversion on the third (3rd) Business Day immediately following the last Trading Day
of such Averaging Period; (ii) if the Company, or any of its Subsidiaries, is obligated to purchase Common Stock pursuant to any such tender offer or exchange offer but is permanently prevented by applicable law from effecting any such purchase
or all such purchases are rescinded, then the Conversion Rate shall be readjusted to be the Conversion Rate that would be in effect if such tender offer or exchange offer had not been made; and (iii) in no event shall an adjustment be made
pursuant to this Section 12.03(e) if such adjustment would result in a reduction to the Conversion Rate. 
 (f) If a
Non-Stock Change of Control occurs and the Conversion Agent receives a conversion notice to convert a Note (whether physically or, if such Note is held in the form of a Global Security, through the Depositary’s conversion program) during the
period (the “Non-Stock Change of Control Period”) after the effective date of such Non-Stock Change of Control and before 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase
Date for such Non-Stock Change of Control (in such case, such Note will be deemed to have been converted “in connection with” such Non-Stock Change of Control), then the Conversion Rate applicable to such conversion shall be increased to
an amount equal to the Conversion Rate that would, but for this Section 12.03(f), otherwise apply to such Note pursuant to this Article XII, plus an amount equal to the Non-Stock Change of Control Applicable Increase. 

As used herein, “Non-Stock Change of Control Applicable Increase” means, with respect to a Non-Stock Change of Control,
the amount, set forth in the following table, which corresponds to the effective date of such Non-Stock Change of Control (the “Effective Date”) and the Stock Price of such Non-Stock Change of Control:

 provided, however, that: 

(i) if the Stock Price of such Non-Stock Change of Control is between two (2) dollar amounts set forth in the table
above in the row immediately below the title “Stock Price” or the Effective Date of such Non-Stock Change of Control is between two (2) dates set forth in the table above in the column titled “Effective Date,” then the
Non-Stock Change of Control Applicable Increase will be determined by straight-line interpolation between the Non-Stock Change of Control Applicable Increases set forth for the higher and lower dollar amounts and such two dates, as applicable, based
on a 360-day year; 
 (ii) if the Stock Price of such Non-Stock Change of Control is greater than eighty three
dollars and fifty cents ($83.50) (as such dollar amount may be adjusted pursuant to clause 

  
 38 

 
(iii) below), or if the Stock Price of such Non-Stock Change of Control is less than thirty five dollars and fifty cents ($35.50) (as such dollar amount may be adjusted pursuant to clause
(iii) below), then the Non-Stock Change of Control Applicable Increase is equal to zero (0); 
 (iii) if an
event occurs that requires, pursuant to this Article XII (other than solely pursuant to this Section 12.03(f)), an adjustment to the Conversion Rate, then, on the date and at the time such adjustment is so required to be made,
(A) each dollar amount set forth in the table above in the row immediately below the title “Stock Price” shall be deemed to be adjusted so that such dollar amount, at and after such time, shall be equal to the product of (1) such
dollar amount as in effect immediately before such adjustment to such dollar amount and (2) a fraction whose numerator is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate and whose denominator is the
Conversion Rate to be in effect, in accordance with this Article XII, immediately after such adjustment to the Conversion Rate; and (B) each Non-Stock Change of Control Applicable Increase amount set forth in the table above shall be
deemed to be adjusted so that such Non-Stock Change of Control Applicable Increase, at and after such time, shall be equal to the product of (1) such Non-Stock Change of Control Applicable Increase as in effect immediately before such
adjustment to such Non-Stock Change of Control Applicable Increase and (2) a fraction whose numerator is the Conversion Rate to be in effect, in accordance with this Article XII, immediately after such adjustment to the Conversion Rate
and whose denominator is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate; and 
 (iv) in no event shall the Conversion Rate applicable to any Note be increased pursuant to this Section 12.03(f) to the extent, but only to the extent, such increase shall cause the number of
shares of Common Stock to be issuable upon conversion of such Note to exceed 29.46376 shares per $1,000 principal amount of such Note (such amount to be adjusted in the same manner in which, and for the same events for which, the Conversion Rate is
to be adjusted pursuant to this Article XII, other than solely pursuant to this Section 12.03(f)). 
 As used
herein, “Stock Price” has the following meaning with respect to a Non-Stock Change of Control: (i) if holders of Common Stock receive only cash in such Non-Stock Change of Control, then the Stock Price will be the cash amount
paid per share in such Non-Stock Change of Control; and (ii) in all other cases, the Stock Price will be the average of the Last Reported Sale Prices per share of Common Stock during the five (5) Trading Days immediately preceding the
Effective Date of such Non-Stock Change Of Control. 
 The Company shall notify Holders and the Trustee of the anticipated
effective date of any Fundamental Change at least twenty (20) calendar days prior to such date. 
 (g) The Company may, in
its sole discretion, from time to time and to the extent permitted by law and any applicable listing standards of the New York Stock Exchange or any other securities exchange on which the Common Stock is then listed, increase the Conversion Rate by
any amount for a period of at least twenty (20) calendar days or such longer period as may be required by law, in which case (i) such Conversion Rate increase will be irrevocable during such period; and (ii) the Company will give
notice to the Trustee and cause notice of such increase to be mailed to each Holder of Notes at least fifteen (15) days prior to the date on which such increase commences. In addition, the Company may, in its sole discretion, from time to time
and to the extent permitted by law and any applicable listing standards of the New York Stock Exchange or any other securities exchange on which the Common Stock is then listed, increase the Conversion Rate as the Board of Directors deems advisable
to avoid or diminish any income tax to holders of Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. 

  
 39 

 (h) Notwithstanding anything to the contrary in the Indenture or the Notes: 

(i) if any dividend or distribution is declared but not paid, then no adjustment to the Conversion Rate shall be made on
account of such dividend, distribution or declaration; 
 (ii) if: 

(A) any rights, options or warrants are issued by the Company; 

(B) the Conversion Rate is adjusted pursuant to this Article XII in connection with such issuance (or the
declaration of the dividend or distribution of such issuance); and 
 (C) any of such rights, options or warrants
are not exercised prior to their expiration or termination, 
 then the Conversion Rate shall be readjusted to the Conversion
Rate which would then be in effect had such adjustment made in connection with such issuance (or the declaration of the dividend or distribution of such issuance) been made on the basis of the delivery of only the consideration actually delivered
upon the exercise of such rights, options or warrants that were actually exercised prior to their expiration or termination; 
 (iii) no adjustment to the Conversion Rate need be made pursuant to this Section 12.03 for any transaction if Holders participate, as a result of holding Notes, in such transaction without
having to convert such Notes, as if each Holder held a number of shares of Common Stock equal to the product of the principal amount of Notes held by such Holder (expressed in thousands) and the Conversion Rate then in effect; 

(iv) if any rights, options or warrants issued by the Company and requiring an adjustment to the Conversion Rate in
accordance with this Section 12.03 are only exercisable upon the occurrence of certain triggering events, then the Conversion Rate will not be adjusted as provided in this Section 12.03 until the earliest of such triggering
events occurs; 
 (v) the Company will not be required to give effect to any adjustment to the Conversion Rate
unless such adjustment would require a change of at least one percent (1%) in the Conversion Rate; provided, however, that each such adjustment that is not given effect shall (A) be carried forward and taken into account in
any subsequent adjustment to the Conversion Adjustment; and (B) unless such adjustment has therefore already been given effect, be given effect (I) five (5) Business Days prior to the Stated Maturity of the principal of the Notes
(whether at the Maturity Date or otherwise); and (2) prior to each Redemption Date or Fundamental Change Repurchase Date; and 
 (vi) the Conversion Rate will not be adjusted for the following: 

(A) the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of
dividends or interest payable on the Company’s securities and the investment of additional option amounts in shares of Common Stock under any plan; 

  
 40 

 (B) the issuance of any shares of Common Stock or options or rights to
purchase shares of Common Stock pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries; 

(C) the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or
convertible security not described in clause (B) and outstanding as of the Issue Date; 
 (D) any change in
the par value of the Common Stock; or 
 (E) accrued and unpaid interest. 

(i) Upon conversion of any Note, the Company shall make provision for the Holder of such Note, to the extent such Holder is to receive
any shares of Common Stock upon such conversion, to receive, in addition to, and concurrently with the delivery of, the Conversion Consideration otherwise payable hereunder upon such conversion, the rights described in each shareholders’ rights
plan of the Company, if any, in effect at the time such Conversion Consideration is delivered in accordance herewith, unless such rights have separated from the Common Stock at such time, in which case the Conversion Rate shall be adjusted upon such
separation in accordance with Section 12.03(c) (subject to the other provisions of this Article XII, including, without limitation, Section 12.03(h)(ii)). So long as the Company complies with this
Section 12.03(i), no adjustment to the Conversion Rate pursuant to Section 12.03(b) or Section 12.03(c) shall be made upon the issuance of any rights pursuant to any such shareholders’ rights plan, unless
such rights have separated from the Common Stock. 
 (j) Except as specifically provided in this Article XII, the
Conversion Rate will not be adjusted for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or carrying the right to purchase any of the foregoing. Except as specifically provided in
the Indenture or the Notes, the Company is not required to make any payment or other adjustment for dividends on any shares of Common Stock issued upon conversion of the Notes. 

(k) All calculations under this Article XII shall be made to the nearest cent or to the nearest one-ten-thousandth
(1/10,000) of a share, as the case may be. 
 12.04. Effect of Certain Reclassifications, Business Combinations, Asset
Sales and Corporate Events. If the Company (whether in one transaction or a series of related transactions): 
 (a)
reclassifies or changes the outstanding Common Stock (other than changes resulting from a subdivision or combination or a change in par value, or from par value to no par value or from no par value to par value); or 

(b) is party to a consolidation, merger or similar transaction or sells, leases, transfers, conveys or otherwise disposes of all or
substantially all of the Company’s assets and those of the Company’s Subsidiaries taken as a whole to another person, 
 and, in each
case, as a result of such reclassification, change, consolidation, merger, transaction, sale, lease, transfer, conveyance or disposition, the holders of Common Stock receive stock, other securities or other property or assets (including, without
limitation cash), or any combination thereof, with respect to or in exchange for their Common Stock (such a reclassification, change, consolidation, merger, transaction, sale, lease, transfer, conveyance or disposition, a “Conversion Right
Adjustment Event”), then the Company or the successor or purchasing Person in such Conversion Right Adjustment Event, as 

  
 41 

 
the case may be, shall, as a condition precedent to such Conversion Right Adjustment Event (and, in the event such successor or purchasing Person is not the Company, the Company shall cause such
successor or purchasing Person to) execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee providing that, at and after the effective time of such Conversion Right Adjustment Event, the Holder of
each Note then outstanding shall have the right to convert such Note (if otherwise convertible pursuant to this Article XII, including, without limitation, Section 12.01(b)) into the kind and amount of stock, other securities or
other property or assets (including, without limitation cash), or any combination thereof (collectively, “Reference Property”), receivable upon such Conversion Right Adjustment Event by a holder of a number of shares of Common Stock
equal to a fraction whose denominator is one thousand dollars ($1,000) and whose numerator is the product of the principal amount of such Note and the Conversion Rate in effect immediately prior to the effective date of such Conversion Right
Adjustment Event (assuming, if holders of Common Stock shall have the opportunity to elect the form of consideration to receive pursuant to such Conversion Right Adjustment Event, that such Holder shall have made the Collective Election with respect
to such election); provided, however, that at and after the effective time of such Conversion Right Adjustment Event, the Aggregate Cash Settlement Amount payable hereunder upon conversion of such Note shall continue to be payable in
cash and the Daily Conversion Value and Daily Net Shares shall be calculated based on the volume-weighted average price (or, if such price is not available, the fair value) of the Reference Property instead of the Daily VWAP per share of Common
Stock; provided further, that if the Reference Property consists solely of cash and such effective time shall occur on or before the fifth (5th) Business Day after the last Trading Day in the Cash Settlement Averaging Period applicable
to the conversion of a Note, then the Conversion Consideration shall be paid by the Company no later than the fifth (5th) Business Day after the later of the Conversion Date for such conversion and such effective date. The supplemental
indenture referred to in the first sentence of this Section 12.04 shall provide for adjustments of the Conversion Rate which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate provided for in
this Article XII. For avoidance of doubt, if a Conversion Right Adjustment Event also constitutes a Non-Stock Change of Control, then each conversion of a Note for which the Conversion Agent receives the related conversion notice (whether
physically or, if such Note is held in the form of a Global Security, through the Depositary’s conversion program) during the applicable Non-Stock Change of Control Period shall be entitled to an increased Conversion Rate pursuant to, and
subject to the conditions of, Section 12.03(f). If such successor or purchasing Person is not the Company, then such supplemental indenture shall provide for the assumption, by such successor or purchasing Person, of the Company’s
obligations under the Indenture and the Notes. If, in the case of any such Conversion Right Adjustment Event, the stock, other securities or other property or assets (including, without limitation cash), or any combination thereof, receivable
thereupon by a holder of Common Stock includes shares of stock or other securities and property of a Person other than the successor or purchasing Person, as the case may be, in such Conversion Right Adjustment Event, then such supplemental
indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors in good faith shall reasonably determine necessary by reason of the
foregoing. The provisions of this Section 12.04 shall similarly apply to successive Conversion Right Adjustment Events. The Company shall not enter into any Conversion Right Adjustment Event unless the terms of such Conversion Right
Adjustment Event are consistent with this Section 12.04. 
 If the Company executes a supplemental indenture
pursuant to this Section 12.04, then the Company will promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind and amount of Reference Property receivable by Holders upon the conversion
of their Notes after any such Conversion Right Adjustment Event and any adjustment to be made with respect thereto. 

  
 42 

 12.05. Proportional Adjustments to Account for Certain Events. Whenever any provision
of the Indenture requires the Company to calculate Last Reported Sale Prices, Closing Sale Prices or Daily VWAPs over a span of multiple days, the Company shall make appropriate adjustments to account for any adjustment to the Conversion Rate that
becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Date of the event occurs, at any time during the period from which such prices are to be calculated. 

12.06. Company to Reserve Stock; Status of Common Stock Issued upon Conversion. The Company shall at all times reserve out of its
authorized but unissued Common Stock or Common Stock held in its treasury enough shares of Common Stock to permit the conversion, in accordance herewith, of all of the Notes. All shares of Common Stock which may be issued upon conversion of the
Notes shall be validly issued, fully paid and non-assessable and shall be free of preemptive or similar rights and free of any lien or adverse claim created by the Company. 
 12.07. Trustee’s Disclaimer. The Trustee has no duty to determine when an adjustment to the Conversion Rate under this Article XII should be made, how it should be made or what such
adjustment should be, but may accept as conclusive evidence of the correctness of any such adjustment and shall be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee
pursuant to Section 12.02(i). The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Notes, and the Trustee shall not be responsible for the failure by the Company to comply
with any provisions of this Article XII. 
 The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed pursuant to Section 12.04, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officers’
Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 12.04. 

Article XIII 
 TAX TREATMENT 
 13.01. Tax Treatment.
The Company agrees, and by purchasing a beneficial ownership interest in the Notes each Holder, and any individual or entity that acquires a direct or indirect beneficial interest in the Notes, will be deemed to have agreed: 

(a) for U.S. federal income tax purposes, to treat the Notes as indebtedness of the Company that is subject to U.S. Treasury Regulations
Section 1.1275-4 (the “Contingent Payment Regulations”); 
 (b) for purposes of the Contingent Payment
Regulations, to treat the fair market value of any shares of Common Stock and cash beneficially received by a beneficial holder upon any conversion of the Notes as a contingent payment; 

(c) to be bound by the Company’s determination that the Notes are contingent payment debt instruments subject to the
“noncontingent bond method” within the meaning of the Contingent Payment Regulations; 
 (d) to accrue original issue
discount at the comparable yield as determined by the Company; and 
 (e) to be bound by the Company’s projected payment
schedule with respect to the Notes. 

  
 43 

 13.02. Comparable Yield and Projected Payment Schedule. Solely for purposes of
applying Treasury Regulation section 1.1275-4 to the Notes: 
 (a) for U.S. federal income tax purposes, the Company shall
accrue interest with respect to outstanding Notes as original issue discount according to the “noncontingent bond method,” as set forth in Treasury Regulation section 1.1275-4(b), using a comparable yield of seven and eleven hundredeths of
one percent (7.11%), compounded semi-annually, and the projected payment schedule as determined by the Company; and 
 (b) the
Company acknowledges and agrees, and each Holder and any beneficial owner of a Note, by its purchase of a Note, shall be deemed to acknowledge and agree, that (A) the comparable yield and the projected payment schedule are not determined for
any purpose other than for the purpose of applying Treasury Regulation section 1.1275-4(b)(4) to the Notes; and (B) the comparable yield and the projected payment schedule do not constitute a projection or representation regarding the future
stock price or the actual amounts payable on the Notes. 
 Holders that wish to obtain the amount of original issue discount,
issue price, issue date, comparable yield and projected payment schedule may do so by submitting a written request to the Company (to the attention of the Vice President, Tax) at the address set forth in Section 14.02 of the Base Indenture.

 Article XIV 
 MISCELLANEOUS 
 14.01. Calculations in Respect of the
Notes. Except as otherwise provided in the Indenture, the Company will be responsible for making all calculations, including, but not limited to, any Coupon Make-Whole Payments, with respect to the Notes called for under the Indenture and the
Notes. The Company or its agents will make all such calculations in good faith, and, absent manifest error, such calculations will be final and binding on Holders. The Company will provide a schedule of such calculations to each of the Trustee and
the Conversion Agent, as appropriate, and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of such calculations without independent verification. The Trustee will forward such calculations to any Holder
upon the request of such Holder. 
 14.02. Scope of this Eighth Supplemental Indenture. The changes, modifications
and supplements to the Base Indenture effected by this Eighth Supplemental Indenture shall only be applicable with respect to, and govern the terms of, the Notes and shall not apply to any other Securities that have been or will be issued by the
Company under the Base Indenture. 
 14.03. Ratification of the Base Indenture. The Base Indenture, as
supplemented by this Eighth Supplemental Indenture, is in all respects ratified and confirmed, and this Eighth Supplemental Indenture shall, for purposes of the Notes, be deemed part of the Base Indenture in the manner and to the extent herein and
therein provided. 
 14.04. Trustee Not Responsible for Recitals. The recitals therein contained are made by the
Company and not by the Trustee, and the Trustee assumes no responsibility for the correctness thereof. The Trustee makes no representation as to the validity or sufficiency of the Base Indenture or this Eighth Supplemental Indenture. 

  
 44 

 14.05. Separability. In case any one or more of the provisions contained in
the Indenture or the Notes shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of the Indenture or the Notes, but the Indenture
and the Notes shall be construed as if such invalid, illegal or unenforceable provision had never been contained in the Indenture or the Notes, as the case may be. 
 14.06. Counterparts. This Eighth Supplemental Indenture may be executed in any number of counterparts, each of which shall be an original, and such counterparts shall together constitute but
one and the same instrument. 
 14.07. Effect of Headings. The Section headings herein are for convenience only
and shall not affect the construction of the Indenture or the Notes. 
 14.08. Governing Law. THE INTERNAL LAWS OF
THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS EIGHTH SUPPLEMENTAL INDENTURE AND THE NOTES, WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICT OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION
WOULD BE REQUIRED THEREBY. 
 14.09. Trust Indenture Act. Notwithstanding anything to the contrary in the Base
Indenture, except with respect to specific provisions of the TIA expressly referenced in the provisions of the Indenture, the TIA shall not be applicable to, and shall not govern, this Eighth Supplemental Indenture and the Notes. 

  
 45 

 IN WITNESS WHEREOF, the parties hereto have
caused this Eighth Supplemental Indenture to be duly executed as of the date first above written.

 [Back of Note] 
 3.75% Convertible Senior Subordinated Notes Due 2042 
 Capitalized terms used
herein shall have the meanings assigned to them in the Indenture (as defined below) unless otherwise indicated. 
  

	 	1.	Interest. 

 Omnicare,
Inc., a Delaware corporation (herein the “Company,” which term includes any successor Person under the Indenture), for value received, hereby promises to pay interest on this Note, semi-annually in arrears at a rate per annum
equal to three and three quarters percent (3.75%), on April 1 and October 1 of each year (each such date, an “Interest Payment Date”), with the first payment to be made on October 1, 2012, to holders of record at 5:00
p.m., New York City time, on the immediately preceding March 15 and September 15, respectively (each such date, the “Regular Record Date,” and the Interest Payment Date immediately following each Regular Record Date shall
be deemed to be the Interest Payment Date that “corresponds” to such Regular Record Date), in each case except as provided in Sections 3.01, 2.06(a), and 4.01(a) of the Eighth Supplemental Indenture (as defined below). Interest on the
Notes will accrue on the principal amount from, and including, the most recent date to which interest has been paid or provided for or, if no interest has been paid, from, and including, April 3, 2012, in each case to, but excluding, the next
Interest Payment Date or the Maturity Date, as the case may be. Interest will be computed on the basis of a 360-day year of twelve 30-day months. On the Maturity Date, the Company will pay accrued and unpaid interest on each Note to the Person to
whom the Company pays the principal amount of such Note, instead of to the Holder on the preceding Regular Record Date. 
 In
addition to the foregoing, beginning with the six (6) month period beginning on, and including, April 1, 2020, (i) if the Contingent Interest Trading Price of the Notes for each Trading Day of the five (5) consecutive Trading Day
period (the “Contingent Interest Measurement Period”) ending on, and including, the second (2nd) Trading Day immediately preceding the first day of any six (6) month period (each such period, a “Contingent Interest
Period”) from, and including, an Interest Payment Date to, but excluding, the next Interest Payment Date, is equal to or greater than the Upside Trigger, then the Company shall pay contingent interest (“Contingent
Interest”) to the Holder of this Note in accordance with Section 2.06(c) of the Eighth Supplemental Indenture and (ii) if the Contingent Interest Trading Price of the Notes for each Trading Day of the Contingent Interest
Measurement Period ending on, and including, the second (2nd) Trading Day immediately preceding the first day of any Contingent Interest Period is less than or equal to the Downside Trigger, then the Company shall pay Contingent Interest to the
Holders of this Note in accordance with Section 2.06(c) of the Eighth Supplemental Indenture. 
 The amount of Contingent
Interest payable per $1,000 principal amount of Notes in respect of any Contingent Interest Period, if applicable, shall (i) in the event that Contingent Interest is payable as a result of the Upside Trigger, be equal to one quarter of one
percent (0.25%) of the average Contingent Interest Trading Price per $1,000 principal amount of the Notes during the five (5) consecutive Trading Days ending on, and including, the second (2nd) Trading Day immediately preceding the first
day of such Contingent Interest Period and (ii) in the event that Contingent Interest is payable as a result of the Downside Trigger, be equal to one half of one percent (0.50%) of the principal amount of such Notes. Contingent Interest shall
accrue from the first day of the applicable Contingent Interest Period through, but excluding, the Interest Payment Date immediately following the end of such Contingent Interest Period, and Contingent Interest shall be payable to Holders in the
same manner as regular cash interest. For avoidance of doubt, regular cash interest shall continue to accrue at the per annum rate of three and three quarters percent (3.75%) on the principal amount of this Note whether or not Contingent
Interest is paid, and Contingent Interest, if any, shall be in addition to such regular cash interest. 

  
 A-4

 As used herein, the term “interest” includes Contingent Interest, if any, but
without duplication. 
  

	 	2.	Method of Payment. 

Except as provided in the immediately following paragraph, principal and interest on this Note will be paid (i) if this Note is held
in the form of Global Security, to the Depositary or its nominee in immediately available funds; (ii) if this Note is a definitive Note that is not held in the form of a Global Security and that has an aggregate principal amount of five million
dollars ($5,000,000) or less, by check mailed to the Holder of this Note; and (iii) if this Note is a definitive Note that is not held in the form of a Global Security and that has an aggregate principal amount of more than five million dollars
($5,000,000), by wire transfer in immediately available funds at the election of the Holder of this Note, which election is duly delivered to the Trustee at least fifteen (15) Business Days before the relevant Interest Payment Date or other
payment date, as applicable. 
 At the Maturity Date, the Company will pay the principal and interest (i) if this Notes is
held in the form of a Global Security, to the Depositary or its nominee in immediately available funds; and (ii) if this Note is a definitive Note that is not held in the form of a Global Security, at the Company’s office or agency in New
York City, which initially will be the Corporate Trust Office of the Trustee in New York City. 
  

	 	3.	Paying Agent, Registrar and Conversion Agent. 

 Initially, the Trustee under the Indenture will act as Paying agent, Registrar and Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion without notice to any Holder. The
Company or any of its Subsidiaries may act in any such capacity. 
  

	 	4.	Indenture.

“Company”), and U.S. Bank National Association (as successor trustee to SunTrust Bank), as trustee (the “Trustee,” which term includes any successor Trustee), as supplemented by the Eighth Supplemental Indenture
(the “Eighth Supplemental Indenture,” and, together with the Base Indenture, the “Indenture”), dated as of April 3, 2012, among the Company, the Guarantors named therein and the Trustee, to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement of the respective rights, duties and limitations of rights and immunities thereunder of the Company, the Guarantors, the Trustees and the Holders of the Notes and of the
terms upon which the Notes are, and are to be, authenticated and delivered. All Notes issued under the Indenture will be treated as a single class of securities under the Indenture. The terms of the Notes include those stated in the Indenture and

and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling to the extent of such conflict.

Indenture. Requests may be made to:

	 	5.	Optional Redemption. 

Subject to, and except as provided in, Article III of the Eighth Supplemental Indenture and Article 3 of the Base Indenture, the Company
shall have the right, at the Company’s option, at any time, on a Redemption Date on or before April 1, 2016, to redeem (a “Redemption”) all or, from time to time, any part of this Note at a Redemption Price payable in cash
equal to the principal amount of the Note to be redeemed, plus the Coupon Make-Whole Payment as of, and accrued and unpaid interest, if any, to, but excluding, such Redemption Date if the Daily VWAP is at least one hundred and fifty percent
(150%) of the then current Conversion Price for each of at least twenty (20) Trading Days in the thirty (30) consecutive Trading Days ending on, and including, the Trading Day prior to the mailing of the notice of Redemption pursuant
to Section 3.03 of the Base Indenture and Section 3.02 of the Eighth Supplemental Indenture. 
 Subject to, and
except as provided in, Article III of the Eighth Supplemental Indenture and Article 3 of the Base Indenture, the Company shall have the right, at the Company’s option, at any time, on a Redemption Date after April 1, 2016, to redeem (also,
a “Redemption”) all or, from time to time, any part of this Note at a Redemption Price payable in cash equal to the principal amount of the Note to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, such
Redemption Date. 
 Notwithstanding the foregoing, and anything to the contrary in the Indenture or this Note, (i) if the
Redemption Date with respect to this Note is after a Regular Record Date for the payment of an installment of interest and on or before the related Interest Payment Date, then accrued and unpaid interest on this Note to, but excluding, such
Redemption Date shall be paid, on such Redemption Date, to the Holder of this Note at the close of business on such Regular Record Date, and the Holder surrendering this Note for Redemption shall not be entitled to any such interest unless such
Holder was also the Holder of record of this Note at the close of business on such Regular Record Date and (ii) in no event shall the Company redeem any Notes at a time when the Company has failed to pay interest on the Notes and such failure
to pay is continuing. 
  

	 	7.	Repurchase of Notes at the Option of Holders Upon Fundamental Change. 

 Subject to, and except as provided in, Article IV of the Eighth Supplemental Indenture, if a Fundamental Change occurs at any time prior to the Maturity Date, then the Holder of this Note, if not
previously repurchased or redeemed by the Company, shall have the right (the “Fundamental Change Repurchase Right”), at such Holder’s option, to require the Company to repurchase all of this Note (or any portion thereof that is
a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof), on a date selected by the Company (the “Fundamental Change Repurchase Date”), which Fundamental Change Repurchase Date shall be no later than thirty
five (35) calendar days, nor earlier than twenty (20) calendar days, after the date the Fundamental Change Repurchase Right Notice is mailed in accordance with Section 4.02 of the Eighth Supplemental Indenture, at a price (the
“Fundamental Change Repurchase Price”), payable in cash, equal to one hundred percent (100%) of the principal amount of this Note to be so repurchased, plus accrued and unpaid interest, if any, to, but excluding, the
Fundamental Change Repurchase Date; provided, however, that if the Fundamental Change Repurchase 

  
 A-6

 
Date with respect to this Note is after a Regular Record Date for the payment of an installment of interest and on or before the related Interest Payment Date, then accrued and unpaid interest on
this Note to, but excluding, such Fundamental Change Repurchase Date shall be paid, on such Fundamental Change Repurchase Date, to the Holder of this Note at the close of business on such Regular Record Date, and the Holder surrendering this Note
for repurchase shall not be entitled to any such interest unless such Holder was also the Holder of record of this Note at the close of business on such Regular Record Date; provided, further, that in no event shall the Company redeem any
Notes at a time when the Company has failed to pay interest on the Notes and such failure to pay is continuing. 
  

	 	10.	Persons Deemed Owners. 

The registered Holder of this Note will be treated as its owner for all purposes. 

 

	 	11.	Amendments, Supplements, Waiver. 

 The Indenture and the Notes may be amended only as provided in Article 9 of the Base Indenture and Article VII of the Eighth Supplemental Indenture. Generally, without the consent of each Holder affected,
an amendment or waiver may not (1) extend the Maturity Date; (2) reduce the rate or extend the time for payment of interest on any Note; (3) reduce the principal amount of any Note; (4) reduce any amount payable upon Redemption

Indenture that does not require the consent of each affected Holder.

Subject to Article 6 of the Base Indenture and Article VI of the Eighth Supplemental Indenture, Events of Default include the following
events: (1) the Company defaults for thirty (30) days in the payment when due of interest on the Notes, whether or not such payment is prohibited by Article 11 of the Base Indenture; (2) the Company defaults in payment when due of the

Subsidiaries (or the payment of which is guaranteed by the Company or any of its Significant Subsidiaries), whether such indebtedness or guarantee exists on, or is created after, the Issue Date, if such default (x) is caused by a failure to pay
principal of such indebtedness at its final stated maturity after giving effect to any 

  
 A-7

 
grace period provided in such indebtedness on the date of such default (a “Payment Default”); or (y) results in the acceleration of such indebtedness prior to its express
maturity, and, in each case, the principal amount of any such indebtedness, together with the principal amount of any other such indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates
one hundred million dollars ($100,000,000) or more; (7) failure by the Company or any of its Significant Subsidiaries to pay final, non-appealable judgments aggregating in excess of one hundred million dollars ($100,000,000) that are not

of a Significant Subsidiary of the Company shall be held in any final, non-appealable judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor that is a Significant Subsidiary
of the Company, or any Person acting on behalf of any such Guarantor, shall deny or disaffirm its obligations under its Subsidiary Guarantee; and (9) certain bankruptcy-related events occur with respect to the Company or any of its Significant
Subsidiaries. 
 The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by notice to the
Trustee (and without notice to any other Holder), may waive an existing Default or Event of Default and its consequences except (i) the failure, by the Company, to pay principal of or interest on any Notes when due; (ii) the failure, by
the Company, to convert any Note in accordance with, and as required by, Article XII of the Eighth Supplemental Indenture; (iii) the failure, by the Company, to pay the Redemption Price on the Redemption Date in accordance with Article III
hereof and Article III of the Eighth Supplemental Indenture in connection with a Redemption or to pay the Fundamental Change Repurchase Price in accordance with Article IV of the Eighth Supplemental Indenture in connection with a Holder’s
exercise of its Fundamental Change Repurchase Right; or (iv) the failure, by the Company, to comply with any of the provisions of the Indenture the amendment of which would require, pursuant to Article 9 hereof, the consent of the Holder of
each outstanding Note affected.

pursuant to the Depositary’s conversion program; and (y) such surrender of this Note pursuant to clause (ii) shall be made by book-entry transfer through the Depositary. Subject to Section 12.02(e) of the Eighth Supplemental
Indenture, this Note will be deemed to have been converted as of 5:00 p.m., New York City time, on the date (such date, the “Conversion Date”) that all the conditions of the immediately preceding sentence have been satisfied.

  
 A-8

 Subject to the terms of the Indenture, upon conversion, the amount of cash and, if
applicable, shares of Common Stock due will be determined based on the Conversion Rates and Daily VWAPs per share of Common Stock during a Cash Settlement Averaging Period.

under the Notes, the Subsidiary Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder, by accepting a Note, waives and releases all such liability. This waiver and
release are part of the consideration for issuance of the Notes. 
  

	 	16.	Guarantees. 

 The payment
by the Company of the principal of and interest on this Note is fully and unconditionally guaranteed on a joint and several basis by each of the Guarantors on the terms set forth in the Indenture. The Subsidiary Guarantee of each Guarantor will be

 Exhibit B 
 FORM OF SUPPLEMENTAL INDENTURE TO BE DELIVERED BY NEW GUARANTORS 

SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of
                    , among
                     (the “New Guarantor”), a subsidiary of Omnicare, Inc. (or its permitted successor), a Delaware
corporation (the “Company”), the Company and U.S. Bank National Association (as successor trustee to SunTrust Bank), as trustee under the Indenture referred to below (the “Trustee”). Capitalized terms used herein

 W I T N E S S E T H 

WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Base
Indenture”), dated as of June 13, 2003, between the Company and the Trustee, as supplemented by the Eighth Supplemental Indenture (the “Eighth Supplemental Indenture,” and, together with the Base Indenture, the
“Indenture”), dated as of April 3, 2012, among the Company, the Guarantors named therein and the Trustee, providing for the issuance of the Company’s 3.75% Convertible Senior Subordinated Notes Due 2042 (the
“Notes”); 
 WHEREAS, the Indenture provides that, under certain circumstances, the New
Guarantor shall execute and deliver to the Trustee a supplemental indenture pursuant to which the New Guarantor shall become a Guarantor under the Indenture and provide a Subsidiary Guarantee with respect to the Notes; and 

WHEREAS, pursuant to Section 9.01 of the Base Indenture, as amended by Section 7.01(a)(x) of the Eighth
Supplemental Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture. 
 NOW
THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the New Guarantor and the Trustee mutually covenant and agree for the equal and ratable benefit
of the Holders of the Notes as follows: 
 1. Agreement to Guarantee. The New Guarantor hereby agrees to be bound by the
Indenture (including, without limitation, Article IX of the Eighth Supplemental Indenture) as if the Guaranteeing Subsidiary had been named as a “Guarantor” in the Indenture. 

2. No Recourse Against Others. No past, present or future director, officer, employee, incorporator or stockholder of the New
Guarantor, as such, shall have any liability for any obligations of the New Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each
Holder, by accepting a Note, waives and releases all such liability. This waiver and release are part of the consideration for issuance of the Notes. 
 7. Governing Law. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE AND THE NOTES, WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF
CONFLICT OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 

  
 B-1

 8. Counterparts. This Supplemental Indenture may be executed in any number of
counterparts, each of which shall be an original, and such counterparts shall together constitute but one and the same instrument. 
 9. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof. 
 10. Trustee Not Responsible. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of
the recitals contained herein, all of which recitals are made solely by the New Guarantor and the Company.

 Exhibit 10.1 
 EXCHANGE AGREEMENT 

                    (the
“Undersigned”), for itself and on behalf of the beneficial owners listed on Exhibit A hereto (“Accounts”) for whom the Undersigned holds contractual and investment authority (each Account, as well as
the Undersigned if it is exchanging Existing Notes (as defined below) hereunder, a “Holder”), enters into this Exchange Agreement (the “Agreement”) with Omnicare, Inc. (the “Company”) on
March     , 2012 whereby the Holders will exchange (the “Exchange”) the Company’s 3.75% Convertible Senior Subordinated Notes due 2025 (the “Existing Notes”) for the Company’s new
3.75% Convertible Senior Subordinated Notes due 2042 (the “New Notes”) that will be issued pursuant to the provisions of an Indenture dated as of June 13, 2003 (the “Base Indenture”) between the Company and
U.S. Bank National Association, as successor Trustee to SunTrust Bank (the “Trustee”), as supplemented by the Eighth Supplemental Indenture thereto, to be dated as of April     , 2012 (the
“Supplement,” and, together with the Base Indenture and all other supplements thereto, the “Indenture”) among the Company, certain subsidiary guarantors party thereto (the “Guarantors”) and the
Trustee. 
 On and subject to the terms hereof, the parties hereto agree as follows: 

Article I: Exchange of the Existing Notes for New Notes 

Subject to the terms set forth in this Agreement, at the Closing (as defined herein), the Undersigned hereby agrees to cause the Holders
to exchange and deliver to the Company the following Existing Notes, and in exchange therefor the Company hereby agrees to issue to the Holders the principal amount of New Notes described below and to pay in cash the following accrued but unpaid
interest on such Existing Notes: 
 Principal Amount of Existing Notes to be Exchanged:
              $
                                         
                                         
       
          (the “Exchanged
Notes”). 
 Principal Amount of New Notes to be Issued in the Exchange: $
                                         
                                         
     
         (the “Holders’ New Notes”).

 Cash Payment of Accrued but Unpaid Interest on Exchanged Notes: $
                                         
                                    

(the “Cash Payment”). 
 The closing of the Exchange (the “Closing”) shall occur on a date (the “Closing Date”) no later than three business days after the date of this Agreement. At the Closing,
(a) each Holder shall deliver or cause to be delivered to the Company all right, title and interest in and to its Exchanged Notes (and no other consideration) free and clear of any mortgage, lien, pledge, charge, security interest, encumbrance,
title retention agreement, option, equity or other adverse claim thereto (collectively, “Liens”), together with any documents of conveyance or transfer that the Company may deem necessary or desirable to transfer to and confirm in
the Company all right, title and interest in and to the Exchanged Notes free and clear of any Liens, and (b) the Company shall deliver to each Holder the principal amount of Holders’ New Notes and the portion of the Cash Payment specified
on Exhibit A hereto (or, if there are no Accounts, the Company shall deliver to the Undersigned, as the sole Holder, the Holders’ New Notes and the Cash Payment specified above); provided, however, that the parties acknowledge that
the delivery of the Holders’ New Notes to the Holder may be delayed due to procedures and mechanics within the system of the Depository Trust Company and that such delay will not be a default under this Agreement so long as (i) the Company
is using its best efforts to effect the issuance of one or more global notes representing the New Notes, (ii) such delay is no longer than three business days, and (iii) interest shall accrue on such New Notes from the Closing Date.
Simultaneously with or after the Closing, the Company may issue New Notes to one or more other holders of outstanding Existing Notes or to other investors, subject to the terms of the Indenture. 

 Article II: Covenants, Representations and Warranties of the Holders

 Each Holder (and, where specified below, the Undersigned) hereby covenants (solely as to itself), as follows, and makes
the following representations and warranties (solely as to itself), each of which is and shall be true and correct on the date hereof and at the Closing, to the Company, Lazard Frères & Co. LLC and Lazard Capital Markets LLC, and all
such covenants, representations and warranties shall survive the Closing. 
 Section 2.1 Power and
Authorization. The Holder is duly organized, validly existing and in good standing, and has the power, authority and capacity to execute and deliver this Agreement, to perform its obligations hereunder, and to consummate the Exchange
contemplated hereby. If the Undersigned is executing this Agreement on behalf of Accounts, (a) the Undersigned has all requisite discretionary and contractual authority to enter into this Agreement on behalf of, and bind, each Account, and
(b) Exhibit A hereto is a true, correct and complete list of (i) the name of each Account, (ii) the principal amount of such Account’s Exchanged Notes, (iii) the principal amount of Holders’ New Notes to be
issued to such Account in respect of its Exchanged Notes, and (iv) the portion of the Cash Payment to be made to such Account in respect of the accrued interest on its Exchanged Notes. 

Section 2.2 Valid and Enforceable Agreement; No Violations. This Agreement has been duly executed and delivered by the
Undersigned and the Holder and constitutes a legal, valid and binding obligation of the Undersigned and the Holder, enforceable against the Undersigned and the Holder in accordance with its terms, except that such enforcement may be subject to
(a) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws affecting or relating to enforcement of creditors’ rights generally, and (b) general principles of equity, whether such enforceability
is considered in a proceeding at law or in equity (the “Enforceability Exceptions”). This Agreement and consummation of the Exchange will not violate, conflict with or result in a breach of or default under (i) the
Undersigned’s or the Holder’s organizational documents, (ii) any agreement or instrument to which the Undersigned or the Holder is a party or by which the Undersigned or the Holder or any of their respective assets are bound, or
(iii) any laws, regulations or governmental or judicial decrees, injunctions or orders applicable to the Undersigned or the Holder. 
 Section 2.3 Title to the Exchanged Notes. The Holder is the sole legal and beneficial owner of the Exchanged Notes set forth opposite its name on Exhibit A hereto (or, if
there are no Accounts, the Undersigned is the sole legal and beneficial owner of all of the Exchanged Notes). The Holder has good, valid and marketable title to its Exchanged Notes, free and clear of any Liens (other than pledges or security
interests that the Holder may have created in favor of a prime broker under and in accordance with its prime brokerage agreement with such broker). The Holder has not, in whole or in part, except as described in the preceding sentence,
(a) assigned, transferred, hypothecated, pledged, exchanged or otherwise disposed of any of its Exchanged Notes or its rights in its Exchanged Notes, or (b) given any person or entity any transfer order, power of attorney or other
authority of any nature whatsoever with respect to its Exchanged Notes. Upon the Holder’s delivery of its Exchanged Notes to the Company pursuant to the Exchange, such Exchanged Notes shall be free and clear of all Liens created by the Holder.

 Section 2.4 Accredited Investor and Qualified Institutional Buyer. The Holder is: (i) an
“accredited investor” within the meaning of Rule 501 of Regulation D (“Regulation D”) promulgated under the Securities Act of 1933, as amended (the “Securities Act”), and (ii) a “qualified
institutional buyer” within the meaning of Rule 144A promulgated under the Securities Act. 
 Section 2.5 No
Affiliate, Related Party or 5% Stockholder Status. The Holder is not, and has not been during the consecutive three month period preceding the date hereof, a director, officer or “affiliate” within the meaning of Rule 144
promulgated under the Securities Act (an “Affiliate”) of the Company. To its knowledge, the Holder did not acquire any of the Exchanged Notes, directly or indirectly, from an Affiliate of

  
 2 

 
the Company. The Holder and its Affiliates collectively beneficially own and will beneficially own as of the Closing Date (but without giving effect to the Exchange) (i) less than 5% of the
outstanding common stock, par value $1.00 per share, of the Company (the “Common Stock”) and (ii) less than 5% of the aggregate number of votes that may be cast by holders of those outstanding securities of the Company that
entitle the holders thereof to vote generally on all matters submitted to the Company’s stockholders for a vote (the “Voting Power”). The Holder is not a subsidiary, affiliate or, to its knowledge, otherwise closely-related to
any director or officer of the Company or beneficial owner of 5% or more of the outstanding Common Stock or Voting Power (each such director, officer or beneficial owner, a “Related Party”). To its knowledge, no Related Party
beneficially owns 5% or more of the outstanding voting equity, or votes entitled to be cast by the outstanding voting equity, of the Holder. 
 Section 2.6 No Illegal Transactions. Each of the Undersigned and the Holder has not, directly or indirectly, and no person acting on behalf of or pursuant to any understanding with it
has, engaged in any transactions in the securities of the Company (including, without limitation, any Short Sales (as defined below) involving any of the Company’s securities) since the time that the Undersigned was first contacted by either
the Company, Lazard Frères & Co. LLC or Lazard Capital Markets LLC or any other person regarding the Exchange, this Agreement or an investment in the New Notes or the Company. Each of the Undersigned and the Holder covenants that
neither it nor any person acting on its behalf or pursuant to any understanding with it will engage, directly or indirectly, in any transactions in the securities of the Company (including Short Sales) prior to the time the transactions contemplated
by this Agreement are publicly disclosed. “Short Sales” include, without limitation, all “short sales” as defined in Rule 200 of Regulation SHO promulgated under the Securities Exchange Act of 1934, as amended (the
“Exchange Act”), and all types of direct and indirect stock pledges, forward sale contracts, options, puts, calls, short sales, swaps, derivatives and similar arrangements (including on a total return basis), and sales and other
transactions through non-U.S. broker-dealers or foreign regulated brokers. Solely for purposes of this Section 2.6, subject to the Undersigned’s and the Holder’s compliance with their respective obligations under the U.S. federal
securities laws and the Undersigned’s and the Holder’s respective internal policies, (a) “Undersigned” and “Holder” shall not be deemed to include any employees, subsidiaries or affiliates of the Undersigned or the
Holder that are effectively walled off by appropriate “Chinese Wall” information barriers approved by the Undersigned’s or the Holder’s respective legal or compliance department (and thus have not been privy to any information
concerning the Exchange), and (b) the foregoing representations of this Section 2.6 shall not apply to any transaction by or on behalf of an Account that was effected without the advice or participation of, or such Account’s receipt
of information regarding the Exchange provided by, the Undersigned. 
 Section 2.7 Adequate Information; No
Reliance. The Holder acknowledges and agrees that (a) the Holder has been furnished with all materials it considers relevant to making an investment decision to enter into the Exchange and has had the opportunity to review the
Company’s filings and submissions with the Securities and Exchange Commission (the “SEC”), including, without limitation, all information filed or furnished pursuant to the Exchange Act, (b) the Holder has had a full
opportunity to ask questions of the Company concerning the Company, its business, operations, financial performance, financial condition and prospects, and the terms and conditions of the Exchange, (c) the Holder has had the opportunity to
consult with its accounting, tax, financial and legal advisors to be able to evaluate the risks involved in the Exchange and to make an informed investment decision with respect to such Exchange and (d) the Holder is not relying, and has not
relied, upon any statement, advice (whether accounting, tax, financial, legal or other), representation or warranty made by the Company or any of its affiliates or representatives including, without limitation, Lazard Frères & Co.
LLC and Lazard Capital Markets LLC, except for (A) the publicly available filings and submissions made by the Company with the SEC under the Exchange Act, and (B) the representations and warranties made by the Company in this Agreement.

 Section 2.8 No Public Market; Call Hedge. The Holder understands that (a) no public market exists for
the New Notes, and that there is no assurance that a public market will ever develop for the New Notes, and (b) the Company may enter into the Call Hedge (as defined below), which may affect the market price per share of Common Stock on an
ongoing basis or periodically after the date hereof.

 Article III: Covenants, Representations and Warranties of the Company

 The Company hereby covenants as follows, and makes the following representations and warranties, each of which is and
shall be true and correct on the date hereof and at the Closing, to the Holders, Lazard Frères & Co. LLC and Lazard Capital Markets LLC, and all such covenants, representations and warranties shall survive the Closing. 

Section 3.1 Power and Authorization. The Company is duly incorporated, validly existing and in good standing under the
laws of its state of incorporation, and has the power, authority and capacity to execute and deliver this Agreement and the Supplement, to perform its obligations hereunder and thereunder, and to consummate the Exchange contemplated hereby. Each
Guarantor is duly organized and validly existing and has the power, authority and capacity to execute and deliver the Supplement and to perform its obligations thereunder. 
 Section 3.2 Valid and Enforceable Agreements; No Violations. This Agreement has been duly executed and delivered by the Company and constitutes a legal, valid and binding obligation of
the Company, enforceable against the Company in accordance with its terms, except that such enforcement may be subject to the Enforceability Exceptions. At the Closing, the Supplement, substantially in the form of Exhibit B hereto, will
have been duly executed and delivered by the Company and the Guarantors and will govern the terms of the New Notes, and the Indenture will constitute a legal, valid and binding obligation of the Company and the Guarantors, enforceable against the
Company and the Guarantors in accordance with its terms, except that such enforcement may be subject to the Enforceability Exceptions. This Agreement, the Indenture and consummation of the Exchange will not violate, conflict with or result in a
breach of or default under (i) the charter, bylaws or other organizational documents of the Company or any of the Guarantors, (ii) any agreement or instrument to which the Company or any of the Guarantors is a party or by which the Company
or any of the Guarantors or any of their respective assets are bound, or (iii) any laws, regulations or governmental or judicial decrees, injunctions or orders applicable to the Company or any of the Guarantors. 

Section 3.3 Validity of the Holders’ New Notes. The Holders’ New Notes have been duly authorized by the
Company and, when executed and authenticated in accordance with the provisions of the Indenture and delivered to the Holder pursuant to the Exchange against delivery of the Exchanged Notes in accordance with the terms of this Agreement, the
Holders’ New Notes will be valid and binding obligations of the Company, enforceable in accordance with their terms, except that such enforcement may be subject to the Enforceability Exceptions, and the Holders’ New Notes will not be
subject to any preemptive, participation, rights of first refusal or other similar rights. Assuming the accuracy of each Holder’s representations and warranties hereunder, the Holders’ New Notes (a) will be issued in the Exchange
exempt from the registration requirements of the Securities Act pursuant to Section 4(2) of the Securities Act, (b) will, at the Closing, be free of any restrictions on resale by such Holder pursuant to Rule 144 promulgated under the
Securities Act, and (c) will be issued in compliance with all applicable state and federal laws concerning the issuance of the Holders’ New Notes. 
 Section 3.4 Validity of Underlying Common Stock. The Holders’ New Notes will at the Closing be convertible into shares of Common Stock (the “Conversion Shares”) in
accordance with the terms of the Supplement. The Conversion Shares have been duly authorized and reserved by the Company for issuance upon conversion of the Holders’ New Notes and, when issued upon conversion of the Holders’ New Notes in
accordance with the terms of the Holders’ New Notes and the Indenture, will be validly issued, fully paid and non-assessable, and the issuance of the Conversion Shares will not be subject to any preemptive, participation, rights of first
refusal or other similar rights. 
 Section 3.5 Listing Approval. At the Closing, the Conversion Shares shall
be eligible for trading on the New York Stock Exchange, subject to official notice of issuance. 

  
 4 

 Section 3.6 Disclosure. On or before the first business day following the
date of this Agreement, the Company shall issue a publicly available press release or file with the SEC a Current Report on Form 8-K disclosing all material terms of the Exchange (to the extent not previously publicly disclosed). 

Article IV: Miscellaneous 
 Section 4.1 Call Hedge. Concurrently with or shortly following its execution of this Agreement, the Company intends to enter into convertible note hedge transactions (the “Call
Hedge”) with one or more counterparties intended to reduce the dilutive impact of the conversion feature of the New Notes on the outstanding shares of Common Stock. The counterparties in these hedge transactions or their respective
affiliates may immediately enter into various transactions (including transactions with Lazard Frères & Co. LLC, Lazard Capital Markets LLC or their respective affiliates) with respect to the Common Stock or related derivative
securities that could have the effect of increasing or preventing a decline in the market price per share of Common Stock. Additionally, such parties may subsequently modify or eliminate their hedge positions through sales of Common Stock or by
unwinding derivatives transactions (such as during New Notes conversion settlement averaging periods) that can have the effect of reducing the value of the consideration to be received upon conversion of New Notes. 

Section 4.2 Entire Agreement. This Agreement and any documents and agreements executed in connection with the Exchange
embody the entire agreement and understanding of the parties hereto with respect to the subject matter hereof and supersede all prior and contemporaneous oral or written agreements, representations, warranties, contracts, correspondence,
conversations, memoranda and understandings between or among the parties or any of their agents, representatives or affiliates relative to such subject matter, including, without limitation, any term sheets, emails or draft documents. 

Section 4.3 Construction. References in the singular shall include the plural, and vice versa, unless the context
otherwise requires. References in the masculine shall include the feminine and neuter, and vice versa, unless the context otherwise requires. Headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect
the meanings of the provisions hereof. Neither party, nor its respective counsel, shall be deemed the drafter of this Agreement for purposes of construing the provisions of this Agreement, and all language in all parts of this Agreement shall be
construed in accordance with its fair meaning, and not strictly for or against either party. 
 Section 4.4 Governing
Law. This Agreement shall in all respects be construed in accordance with and governed by the substantive laws of the State of New York, without reference to its choice of law rules. 

Section 4.5 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original,
but all of which taken together shall constitute one and the same instrument. Any counterpart or other signature hereon delivered by facsimile shall be deemed for all purposes as constituting good and valid execution and delivery of this Agreement
by such party.
