Interest Payment Date to the Person in whose name the Series B Senior Notes are registered on the Regular Record Date for such Interest Payment Date; provided that interest payable at the Stated Maturity of principal or on a Redemption Date as
provided herein will be paid to the Person to whom principal is payable. Any such interest that is not so punctually paid or duly provided for will forthwith cease to be payable to the Holders on such Regular Record Date and may either be paid to
the Person or Persons in whose name the Series B Senior Notes are registered at the close of business on a Special Record Date for the payment of such defaulted interest to be fixed by the Trustee (in accordance with Section 307 of the Base

with the same force and effect as if made on the date the payment was originally payable. 
 Payment of the principal and interest on the
Series B Senior Notes shall be made at the office of the Paying Agent in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts, with any such payment that is due at
the Stated Maturity of any Series B Senior Notes, upon redemption or repurchase being made upon surrender of such Series B Senior Notes to the Paying Agent. Payments of interest (including interest on any Interest Payment Date) will be made, subject

account at a banking institution in the United States as may be designated in writing to the Trustee at least sixteen (16) days prior to the date for payment by the Person entitled thereto. In the event that any date on which principal and

any such delay), in each case with the same force and effect as if made on the date the payment was originally payable.

Denominations. The Series B Senior Notes may be issued in denominations of $2,000, or any greater integral multiple of $1,000. 

SECTION 105. Global Securities. The Series B Senior Notes will be initially issued in the form of one or more Global Securities
registered in the name of the Depositary (which shall be The Depository Trust Company) or its nominee. Except under the limited circumstances described below, Series B Senior Notes represented by such Global Securities will not be exchangeable for,
and will not otherwise be issuable as, Series B Senior Notes in definitive form registered in names other than the Depositary or its nominee. The Global Securities described above may not be transferred except by the Depositary to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or to a successor Depositary or its nominee. 

Owners of beneficial interests in such a Global Security will not be considered the Holders thereof for any purpose under the Indenture, and
no Global Security representing a Series B Senior Note shall be exchangeable, except for another Global Security of like denomination and tenor to be registered in the name of the Depositary or its nominee or to a successor Depositary or its nominee
or except as described below. The rights of Holders of such Global Security shall be exercised only through the Depositary. 
 A Global
Security shall be exchangeable for Series B Senior Notes registered in the names of persons other than the Depositary or its nominee only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as a Depositary for
such Global Security and no successor Depositary shall have been appointed by the Company within 90 days of receipt by the Company of such notification, or if at any time the Depositary ceases to be a clearing agency registered under the Exchange
Act at a time when the Depositary is required to be so registered to act as such Depositary and no successor Depositary shall have been appointed by the 

  
 5 

 
Company within 90 days after it becomes aware of such cessation, (ii) the Company in its sole discretion, and subject to the procedures of the Depositary, determines that such Global
Security shall be so exchangeable, in which case Series B Senior Notes in definitive form will be printed and delivered to the Depositary, or (iii) an Event of Default has occurred and is continuing with respect to the Series B Senior Notes.
Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Series B Senior Notes registered in such names as the Depositary shall direct. 

SECTION 106. Redemption. The Series B Senior Notes are redeemable, in whole or in part, at any time and from time to time prior to
December 15, 2021, at the option of the Company, at a Redemption Price equal to the greater of: 
 (i) 100% of the principal amount of
Series B Senior Notes then Outstanding to be so redeemed, or 
 (ii) the sum of the present values of the remaining scheduled payments of
principal and interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the
Adjusted Treasury Rate, plus 15 basis points, as calculated by an Independent Investment Banker, 
 plus, in either of the above cases, accrued and unpaid
interest thereon to the Redemption Date. 
 In addition, the Series B Senior Notes are redeemable, in whole or in part at any time and from
time to time on or after December 15, 2021, at the option of the Company, at a Redemption Price equal to 100% of the principal amount of the Series B Senior Notes then outstanding to be redeemed, plus accrued and unpaid interest thereon to the
Redemption Date. 
 The Adjusted Treasury Rate shall be calculated no later than the third Business Day preceding the Redemption Date. 

Unless the Company defaults in the payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the
Series B Senior Notes or portions thereof called for redemption. 
 In the event of the redemption of the Series B Senior Notes in part
only, a new Series B Senior Note or Notes for the unredeemed portion will be issued in the name or names of the Holders thereof upon surrender thereof. 

The Company shall notify the Trustee in writing of the Redemption Price promptly after the calculation thereof and the Trustee shall have no
responsibility for such calculation. The notice of redemption shall be sent in accordance with the terms of the Base Indenture. 
 SECTION
107. Sinking Fund; Conversion. The Series B Senior Notes shall not have a sinking fund. The Series B Senior Notes are not convertible into or exchangeable for Equity Securities and/or any other securities.

 SECTION 108. Additional Interest on Overdue Amounts. Any principal of and installment of
interest on the Series B Senior Notes that is overdue shall bear interest at the rate of 2.75% (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they are paid or made available
for payment, and such interest shall be payable on demand. 
 SECTION 109. Paying Agent. The Trustee shall initially serve as Paying
Agent with respect to the Series B Senior Notes, with the Place of Payment initially being the Corporate Trust Office.

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be
issued in one or more series under an Indenture dated as of June 1, 2015 (the “Base Indenture”), between the Company and Deutsche Bank Trust Company Americas, as Trustee (the “Trustee”), as previously supplemented and as
further supplemented by a Tenth Supplemental Indenture dated as of January 1, 2017 (the “Tenth Supplemental Indenture” and, together with the Base Indenture, as it may be hereafter supplemented or amended from time to time, the
“Indenture,” which term shall have the meaning assigned to it in such instrument), by and between the Company and the Trustee, and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights,

 The Series B Senior Notes are
redeemable, in whole or in part, at any time and from time to time in the manner and with the effect provided in the Indenture. 
 If an
Event of Default with respect to Series B Senior Notes shall occur and be continuing, the principal of the Series B Senior Notes may be declared due and payable in the manner and with the effect provided in the Indenture. 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations
of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee for the series of Securities affected, with the consent of the Holders of a majority in
principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Series B Senior Note shall be conclusive and binding
upon such Holder and upon all future Holders of this Series B Senior Note and of any Series B Senior Note issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Series B Senior Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Series B Senior
Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of
a continuing Event of Default with respect to the Series B Senior Notes, the Holders of not less than a majority in principal amount of the Series B Senior Notes at the time Outstanding shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity or security reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Series B Senior
Notes at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such 

  
 4 

 
proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Series B Senior Note for the
enforcement of any payment of principal hereof or premium, if any, or interest hereon on or after the respective due dates expressed or provided for herein. 

No reference herein to the Indenture and no provision of this Series B Senior Note or of the Indenture shall alter or impair the obligation of
the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Series B Senior Note at the times, place and rate, and in the coin or currency, herein prescribed. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Series B Senior Note is registrable in
the Security Register, upon surrender of this Series B Senior Note for registration of transfer at the office or agency of the Company in any place where the principal of, premium, if any, and interest on this Series B Senior Note are payable, duly
endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Series B
Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Series B Senior Notes are issuable only in registered form without coupons in denominations of $2,000 and any greater integral multiple of
$1,000. As provided in the Indenture and subject to certain limitations therein set forth, Series B Senior Notes are exchangeable for a like aggregate principal amount of Series B Senior Notes having the same Stated Maturity and of like tenor of any
authorized denominations as requested by the Holder upon surrender of the Series B Senior Note or Series B Senior Notes to be exchanged at the office or agency of the Company. 

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this Series B Senior Note for
registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Series B Senior Note be overdue,
and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 All terms used in this Series B
Senior Note that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Corporation entitled to vote thereon, in person, by written consent or by proxy, within twelve (12) months of the adoption of the Plan by the Board of Directors in accordance with the Corporation Law or Section 422 of the Code. No Option

by its terms and Options or Rights previously granted shall terminate. 
 (b) Any Option granted pursuant to this Plan shall be granted
within ten (10) years from the date that this Plan is adopted by the Board of Directors or the date that this Plan is approved by the stockholders of the Corporation, whichever is earlier. 

(c) The Board of Directors shall implement, interpret (except as expressly provided in this Plan) and administer this Plan. Without limiting
the powers and authority of the Board of Directors in any respect, the Board of Directors shall have authority: 
 (i) to construe and
interpret this Plan and any Stock Option Agreement or Restricted Stock Agreement entered into hereunder;

may delegate any or all of its responsibilities hereunder to the Committee, and all references herein or in any Stock Option Agreement or Restricted Stock Agreement to the “Board of Directors” shall, to the extent applicable, be deemed to
refer to and include the Committee. Furthermore, the Board of Directors or the Committee may delegate its responsibilities to any officer or officers of the Corporation upon terms and conditions specified in such delegation subject to specified

	 	4.	Total Number of Shares of Incentive Stock. 

 The number of shares of Incentive Stock
which (i) may be issued by the Corporation under this Plan pursuant to the exercise of Options granted hereunder and (ii) may be issued by the Corporation under this Plan pursuant to the exercise of Rights granted hereunder, shall not
exceed an aggregate of Thirty-One Million Eight Hundred Forty Six Thousand Three Hundred (31,846,300) shares, which amount may be increased only as provided in Section 9 hereof or by a resolution adopted by the Board of Directors and
approved by the 

  
 4 

 
stockholders holding at least a majority of the outstanding shares of capital stock of the Corporation entitled to vote thereon in accordance with the Corporation Law or Section 422 of the
Code within twelve (12) months after such adoption by the Board of Directors. Such shares of Incentive Stock may be issued out of the authorized and unissued or reacquired Common Stock of the Corporation. Any shares subject to an Option, Right
or portion thereof which expires or is terminated unexercised (unless by virtue of the exercise of an Option or Right granted in tandem therewith) as to such shares may again be subject to an Option or Right under this Plan. To the extent there
shall be any adjustment in the number of shares of Incentive Stock pursuant to the provisions of Section 9 hereof, the aforesaid aggregate number of shares which may be issued by the Corporation under this Plan shall be likewise adjusted. 

 

	 	5.	Grants and Awards. 

 (a) As soon as practicable after the Board of Directors determines
to award an Option or Right, the appropriate officer or officers of the Corporation shall give notice (written, electronic or oral) to such effect to each Eligible Person designated to be awarded an Option or Right, which notice shall be accompanied
by a copy or copies of the Stock Option Agreement or Restricted Stock Agreement (as applicable), if any, to be executed by such Eligible Person. The Board of Directors may delegate to the appropriate officer or officers of the Corporation the
authority to prepare, execute and deliver any Stock Option Agreement or Restricted Stock Agreement evidencing any Option or Right granted under this Plan; provided, however, that any such Stock Option Agreement or Restricted Stock
Agreement shall be consistent with the terms and conditions of this Plan. 
 (b) Upon receipt of the notice specified in Section 5(A)
hereof, an Eligible Person shall have an Option or Right (as the case may be). Such Eligible Person shall nonetheless become and be a Participant only after the due execution (by written or electronic means) and delivery by such Eligible Person and
the Corporation of a Stock Option Agreement or Restricted Stock Agreement (in such form and number as the officer or officers of the Corporation shall direct) by such date and time as shall be specified in such notice (unless waived by the
Corporation); provided, however, that the Board of Directors may determine in any instance that an Eligible Person shall become a Participant upon such Participant’s receipt of the notice specified in Section 5(A) hereof and
not require the execution and delivery of any Stock Option Agreement or Restricted Stock Agreement by any Eligible Person. 
 (c) For any
Option intended to qualify as an ISO, in whole or in part, (i) the Eligible Person shall then be an employee of the Corporation or a Parent or Subsidiary, as provided in the Code; (ii) the term during which such Option shall be in effect
shall not be greater than ten (10) years, except in the case of an Option granted to a Controlling Participant, in which case the term shall not be greater than five (5) years; (iii) the Exercise Price shall not be less than one
hundred percent (100%) of the Fair Market Value on the date that such Option is granted, except in the case of an Option granted to a Controlling Participant, in which case the Exercise Price shall not be less than one hundred ten percent
(110%) of the Fair Market Value on the date that such Option is granted; (iv) such Option shall be exercisable only by the Participant during his or her lifetime and shall be nontransferable by the Participant unless the Stock Option
Agreement permits such Option to be transferred by will or the laws of descent and distribution; and (v) such Option may be exercised up to ninety (90) days after the date of termination of

  
 5 

 
Participant’s employment (except for termination for cause or due to death), or for up to six (6) months if termination is due to Participant’s death. 

(d) The purchase price for each share of Restricted Stock, as determined by the Board of Directors, need not be the Fair Market Value thereof,
and may vary from one Participant to another. In addition, the terms and conditions on which shares of Restricted Stock may be purchased may vary from one Participant to another. In computing the purchase price of a share of Restricted Stock, the
Board of Directors may take into consideration, without limitation, the restrictions on transfer or other disposition imposed in the applicable Restricted Stock Agreement. 

(e) In the event that the Corporation or any Parent or Subsidiary assumes an option granted by another entity, which option is to be covered by
this Plan and upon the exercise of which shares of Incentive Stock are to be issued, the terms and conditions of such option shall remain unchanged (except the exercise price and the number and nature of shares issuable upon exercise thereof, which
shall be adjusted appropriately in accordance with the Code, and references to such other entity, which shall be deemed to refer to the Corporation). In the event that the Board of Directors elects to grant an Option or Right under this Plan to
replace an option or right granted by another entity (rather than assume such option or right), the holder of such option shall be eligible to receive such replacement Option or Right, which may be granted with a similarly-adjusted Exercise Price.

  

	 	6.	Exercise and Termination of Options and Rights. 

 (a) Unless the applicable Stock Option
Agreement provides otherwise, any Option granted pursuant to this Plan to any employee of the Corporation or any Parent or Subsidiary shall cease vesting upon the termination of such employee’s employment with such entity. An Option of a
Participant may be exercised during the period such Option is in effect and as set forth herein and in the Stock Option Agreement, and only if compliance with all applicable federal and state securities laws can be effected. An Option may be
exercised only by (i) the Participant’s completion, execution and delivery to the Corporation of a notice (written or electronic) of such Participant’s exercise of such Option and an “investment letter” (if required by the
Corporation) as supplied by the Corporation and (ii) the payment to the Corporation of the aggregate Exercise Price, in accordance with Section 6(C) hereof and the Stock Option Agreement, for the shares of Incentive Stock to be purchased
pursuant to such exercise (as shall be specified by such Participant in such notice). Except as otherwise specifically provided by a duly executed Stock Option Agreement or unless waived by the Board of Directors, an Option or any of the rights
thereunder may be exercised by such Participant only, and may not be transferred or assigned, voluntarily, involuntarily or by operation of law (including, without limitation, the laws of bankruptcy, intestacy, descent and distribution and
succession). 
 (b) A Right of a Participant may be exercised during the period such Right is in effect and as set forth herein and in the
Restricted Stock Agreement, and only if compliance with all applicable federal and state securities laws can be effected. A Right may be exercised only by the Participant’s completion, execution and delivery to the Corporation of a notice
(written or electronic) of such Participant’s exercise of such Right (if such exercise is not simultaneous with the execution of the applicable Restricted Stock Agreement) and an 

  
 6 

 
“investment letter” (in each case if required by the Corporation) as supplied by the Corporation. Except as otherwise specifically provided by a duly executed Restricted Stock Agreement
or unless waived by the Board of Directors, a Right or any of the rights thereunder may be exercised by such Participant only, and may not be transferred or assigned, voluntarily, involuntarily or by operation of law (including, without limitation,
the laws of bankruptcy, intestacy, descent and distribution and succession). 
 (c) Payment by each Participant for the shares of Incentive
Stock or Restricted Stock purchased hereunder upon the exercise of an Option or a Right shall be made in accordance with the terms of the applicable Stock Option Agreement or Restricted Stock Agreement executed by such Participant. 

(d) The Board of Directors at any time or from time to time may offer to buy out for a payment in cash or Incentive Stock all or a portion of
an outstanding Option held by a Participant, based on such terms and conditions as the Board of Directors shall establish and communicate to the Participant at the time that such offer is made. The Board of Directors may provide for the surrender of
all or any portion of an Option in satisfaction of specified obligations of a Participant, including tax withholding obligations. 
 (e) As a
condition to the exercise of any Option (for non-cash consideration), the Corporation shall have the right to require that the Participant (or the recipient of any shares of Incentive Stock or non-cash consideration) remit to the Corporation or any
Parent or Subsidiary an amount calculated by the Corporation to be sufficient to satisfy applicable federal, state, foreign or local withholding tax requirements prior to the delivery of any stock certificate evidencing shares of Incentive Stock or
other form of non-cash consideration; in lieu thereof, the Participant may satisfy applicable withholding tax requirements by electing to have the Corporation withhold from the Incentive Stock issuable upon exercise of an Option a number of whole
shares having a Fair Market Value (determined on the date that the amount of tax to be withheld is to be fixed) at least equal to the aggregate amount required to be withheld. Whenever any payments are to be made in cash, the Corporation shall be
entitled, in its sole discretion, to deduct from such payment such amount calculated by the Corporation to be sufficient to satisfy applicable federal, state, foreign or local withholding tax requirements thereon. 

 

	 	7.	Costs and Expenses. 

 All costs and expenses with respect to the adoption,
implementation, interpretation and administration of this Plan shall be borne by the Corporation; provided, however, that, except as otherwise specifically provided in this Plan or the applicable Stock Option Agreement or Restricted
Stock Agreement between the Corporation and a Participant, the Corporation shall not be obligated to pay any costs or expenses (including legal fees) incurred by any Participant in connection with any Stock Option Agreement, Restricted Stock

	 	8.	No Prior Right of Award. 

 Nothing in this Plan shall be deemed to give any director,
officer or employee of, or advisor or consultant to, the Corporation or any Parent or Subsidiary, or such person’s legal representatives or assigns, or any other person or entity claiming under or through such person, any contract or other
right to participate in the benefits of this Plan. Nothing in this Plan shall be construed as constituting a commitment, guarantee, agreement or understanding of any kind or nature that the Corporation or any Parent or Subsidiary shall continue to
employ, retain or engage any person (whether or not a Participant). This Plan shall not affect in any way the right of the Corporation and any Parent or Subsidiary to terminate the employment or engagement of any person (whether or not a
Participant) at any time and for any reason whatsoever and to remove any person (whether or not a Participant) from any position as a director or officer. No change of a Participant’s duties as an employee of the Corporation or any Parent or
Subsidiary shall result in a modification of the terms of any rights of such Participant under this Plan or any Stock Option Agreement or Restricted Stock Agreement executed by such Participant. 

 

	 	9.	Changes in Capital Structure. 

 Subject to any required action by the stockholders of the
Corporation and the provisions of the Corporation Law, the number of shares of: 
 (i) Incentive Stock represented by the unexercised
portion of an Option or Right; and 
 (ii) Incentive Stock which has been authorized or reserved for issuance hereunder (whether such shares
are unissued, reacquired or subject to an Option or Right that expired, was cancelled, surrendered or terminated unexercised as to such shares), 
 as well
as the Exercise Price under the unexercised portion of an Option and the purchase price of a share of Restricted Stock represented by the unexercised portion of a Right, shall be proportionately adjusted for (a) each stock split, reverse split,
stock dividend, division, combination, recapitalization or reclassification of any of the shares of Common Stock of the Corporation and (b) each dividend declared by the Board of Directors and payable in shares of Common Stock of the
Corporation. 
  

	 	10.	Plan History; Amendment or Termination of Plan. 

 Except as otherwise provided herein or
as required by law, this Plan may be amended or terminated in whole or in part by the Board of Directors (in its sole discretion), but no such action shall adversely affect or alter any right or obligation with respect to any Option, Right, Stock
Option Agreement or Restricted Stock Agreement then in effect, except to the extent that any such action shall be required or desirable (in the opinion of the Corporation or its counsel) so that any Option intended to qualify as an ISO complies with
the Code or any rule or regulation promulgated or proposed thereunder. This Plan was originally adopted in 2005. The Plan subsequently was amended in 2009. Effective April 7 2016, the Plan is amended and restated, subject to approval by the
stockholders of the Corporation, such that it is effective for one (1) year from December 31, 2015 (such anniversary, the “Restatement Termination Date”). The Plan shall terminate on the Restatement Termination Date.

	 	11.	Voting. 

 The Common Stock received upon the exercise of any Option or the purchase of
Restricted Stock shall have equal voting rights as other outstanding shares of Common Stock on all matters where such vote is permitted by applicable law. 
  

	 	12.	Burden and Benefit. 

 The terms and provisions of this Plan shall be binding upon, and
shall inure to the benefit of, each Participant and such Participant’s executors and administrators, estate, heirs and personal and legal representatives. 
  

	 	13.	Headings. 

 The headings and other captions contained in this Plan are for convenience of
reference only and shall not be used in interpreting, construing or enforcing any of the provisions of this Plan. 
  

	 	14.	Interpretation. 

 Notwithstanding any provision of this Plan or any provision of any
Stock Option Agreement evidencing an Option that is intended, in whole or in part, to qualify as an ISO, this Plan and each such Stock Option Agreement are intended to comply with all requirements for qualification under the Code and with any rule
or regulation promulgated or proposed thereunder, and shall be interpreted and construed in a manner which is consistent with this Plan and each such Stock Option Agreement being so qualified. 

 

	 	15.	Governing Law. 

 This Plan shall be governed by, and construed in accordance with, the
substantive laws of the State of Delaware (other than provisions thereof relating to conflicts of law and choice of law), except to the extent that such law is preempted by Federal law.
