      2005
Stock Incentive Plan

       

      (as
of March 25, 2008)

       

      INTRODUCTION

       

      Cover-All
Technologies Inc., a Delaware corporation (hereinafter referred to as the
“Corporation”), hereby establishes an incentive compensation plan to be known as
the “Cover-All Technologies Inc. 2005 Stock Incentive Plan” (hereinafter
referred to as the “Plan”), as set forth in this document.  The Plan
permits the grant of Non-Qualified Stock Options, Incentive Stock Options and
stock awards.

       

      The Plan
shall become effective upon the later of the date on which it is adopted by the
Board of Directors of the Corporation and the date on which it is approved by
the Corporation’s stockholders, which is anticipated to be June 7,
2005.  The Plan was Amended and Restated as of May 9, 2006 in order to
clarify the exercise period following termination of employment for Good Cause
set forth in Section V(g) hereof.  The Plan was further Amended and
Restated as of March 25, 2008 in order to make the Company’s directors (who are
not employees) eligible Participants under the Plan.

       

      The
purpose of the Plan is to promote the success and enhance the value of the
Corporation by linking the personal interests of Participants to those of the
Corporation’s stockholders, customers and employees, by providing Participants
with an incentive for outstanding performance.  The Plan is further
intended to provide flexibility to the Corporation in its ability to motivate,
and retain the services of, Participants upon whose judgment, interest and
special effort the successful conduct of its operations is largely
dependent.

       

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

      

      DEFINITIONS

       

      For

the context clearly indicates otherwise:

       

      (a)           “Change in Control”
shall mean:  (i) the acquisition (other than from the
Corporation) in one or more transactions by any Person, as defined in this
Section, of the beneficial ownership (within the meaning of Rule 13d-3

more of (A) the then outstanding shares of the securities of the
Corporation, or (B) the combined voting power of the then outstanding
securities of the Corporation entitled to vote generally in the election of
directors (the “Corporation Voting Stock”); (ii) the closing of a sale or
other conveyance of all or substantially all of the assets of the Corporation;

Stock; provided, however, that for
purposes of any Plan Award or subplan that constitutes a “nonqualified deferred
compensation plan,” within the meaning of Code section 409A, the Committee, in
its discretion, may specify a different definition of Change in Control in order
to comply with the provisions of Code section 409A.  For purposes of
this Section, a “Person” means any individual, entity or group within the

of the Common Stock or, if no sale is publicly reported, the average of the
closing bid and asked quotations for the Common Stock, as reported by the
National Association of Securities Dealers Automated Quotation System (“NASDAQ”)

shall be administered by the Committee.  Subject to the provisions of
the Plan, the Committee may establish from time to time such regulations,
provisions, proceedings and conditions of Plan Awards which, in its opinion, may
be advisable in the administration of the Plan.  A majority of the

      Subject
to the adjustments provided in Section VII of the Plan, the aggregate number of
shares of the Common Stock which may be granted for all purposes under the Plan
shall be five million (5,000,000) shares.  Shares of Common Stock
underlying Plan Awards shall be counted against the limitation set forth in the

Plan Award, under the Plan expires or terminates unexercised, becomes
unexercisable, is settled in cash without delivery of shares of Common Stock, or
is forfeited or otherwise terminated, surrendered or canceled as to any shares,
or if any shares of Common Stock are repurchased by or surrendered to the
Corporation in connection with any Plan Award (whether or not such surrendered
shares were acquired pursuant to any Plan Award), or if any shares are withheld
by the Corporation, the shares subject to such Plan Award and the repurchased,
surrendered and withheld shares shall thereafter be available for further Plan
Awards under the Plan; provided, however, that any
such shares that are surrendered to or repurchased or withheld by the
Corporation in connection with any Plan Award or that are otherwise forfeited
after issuance shall not be available for grant of Incentive Stock
Options.  Plan Awards under the Plan may be fulfilled in accordance
with the terms of the Plan with either authorized and unissued shares of the
Common Stock, issued shares of such Common Stock held in the Corporation’s
treasury or shares of Common Stock acquired on the open market.

as may be selected by the Committee from time to time.  The Committee
may also grant Plan Awards to individuals in connection with hiring, retention
or otherwise, prior to the date the individual first performs services for the
Corporation or a Parent or Subsidiary, provided that such Plan Awards shall not

      SECTION
IV

      AUTHORITY
OF COMMITTEE

       

      The Plan
shall be administered by, or under the direction of, the Committee, which shall
administer the Plan so as to comply at all times with the Exchange Act, to the
extent such compliance is required, and, subject to the Code, shall otherwise
have plenary authority to interpret the Plan and any grant agreements under the
Plan, and to make all determinations specified in or permitted by the Plan or
deemed necessary or desirable for its administration or for the conduct of the
Committee’s business.  Subject to the provisions of Section XI hereof,
all interpretations and determinations of the Committee may be made on an
individual or group basis and shall be final, conclusive and binding on all
interested parties.  Subject to the express provisions of the Plan,
the Committee shall have authority, in its discretion, to determine the persons
to whom Plan Awards shall be granted, the times when such Plan Awards shall be
granted, the number of Plan Awards, the purchase price or exercise price of each
Plan Award, the period(s) during which such Plan Award shall be exercisable
(whether in whole or in part), the restrictions to be applicable to Plan Awards
and the other terms and provisions thereof (which need not be
identical).  In addition, the authority of the Committee (which may be
exercised in its sole discretion) shall include without limitation the
following:

       

      (a)           Financing.  The
arrangement of temporary financing for an Optionee by registered broker-dealers,
under the rules and regulations of the Federal Reserve Board, for the purpose of
assisting the Optionee in the exercise of an Option, such authority to include
the payment by the Corporation of the commissions of the
broker-dealer;

       

      (b)           Procedures for Exercise of
Option.  The establishment of procedures for an Optionee (i) to
exercise an Option by payment of cash or any other property acceptable to the
Committee, (ii) to have withheld from the total number of shares of Common Stock
to be acquired upon the exercise of an Option that number of shares having a
Fair Market Value, which, together with such cash as shall be paid in respect of
fractional shares, shall equal the option exercise price of the total number of
shares to be acquired, (iii) to exercise all or a portion of an Option by
delivering that number of shares of Common Stock already owned by him having a
Fair Market Value which shall equal the Option exercise price for the portion
exercised and, in cases where a Option is not exercised in its entirety, to
permit the Optionee to deliver the shares of Common Stock thus acquired by him
in payment of shares of Common Stock to be received pursuant to the exercise of
additional portions of such Option, the effect of which shall be that an
Optionee can in sequence utilize such newly acquired shares of Common Stock in
payment
of the exercise price of the entire option, together with such cash as shall be
paid in respect of fractional shares, and (iv) to engage in any form of
“cashless” exercise;

      (c)           Withholding.  The
establishment of a procedure whereby a number of shares of Common Stock or other
securities may be withheld from the total number of shares of Common Stock or
other securities to be issued upon exercise of an Option or for the tender of
shares of Common Stock owned by the Participant to meet the obligation of
withholding for taxes incurred by the Optionee upon such exercise;
and

       

      (d)           Types of Plan
Awards.  The Committee may grant awards in the form of one or
more of Incentive Stock Options, Non-Qualified Stock Options and stock
awards.

       

       

      SECTION
V

      STOCK
OPTIONS

       

      The
Committee shall have the authority, in its discretion, to grant Incentive Stock
Options or to grant Non-Qualified Stock Options or to grant both types of
Options.  No Option shall be granted for a term of more than ten (10)
years.  Notwithstanding anything contained herein to the contrary, an
Incentive Stock Option may be granted only to common law employees of the
Corporation or of any Parent or Subsidiary now existing or hereafter formed or
acquired, and not to any director (who is not an employee) or consultant who is
not also such a common law employee.  The terms and conditions of the
Options shall be determined from time to time by the Committee; provided, however, that the
Options granted under the Plan shall be subject to the following:

       

      (a)           Exercise
Price.  The Committee shall establish the exercise price at the
time any Option is granted at such amount as the Committee shall determine;
provided, however, that the
exercise price for each share of Common Stock purchasable under any Incentive
Stock Option granted hereunder shall be such amount as the Committee shall, in
its best judgment, determine to be not less than one hundred percent (100%) of
the Fair Market Value per share of Common Stock at the date the Option is
granted; and provided, further, that in the
case of an Incentive Stock Option granted to a person who, at the time such
Incentive Stock Option is granted, owns shares of stock of the Corporation or of
any Parent or Subsidiary which possess more than ten percent (10%) of the total
combined voting power of all classes of shares of stock of the Corporation or of
any Parent or Subsidiary, the exercise price for each share of Common Stock
shall be such amount as the Committee, in its best judgment, shall determine to
be not less than one hundred ten percent (110%) of the Fair Market Value per
share of Common Stock at the date the Option is granted.  The exercise
price will be subject to adjustment in accordance with the provisions of Section
VII of the Plan.

       

      (b)           Payment of Exercise
Price.  The price per share of Common Stock with respect to
each Option shall be payable at the time the Option is
exercised.  Such price shall be payable in cash or, upon the
discretion of the Committee, pursuant to any of the methods set forth in
Sections IV(a) or (b) hereof.  Shares of Common Stock delivered to the
Corporation in payment of the exercise price shall be valued at the Fair Market
Value of the Common Stock on the date preceding the date of the exercise of the
Option.

      (c)           Exercisability of
Options.  Each Option shall be exercisable in whole or in
installments, and at such time(s), and subject to the fulfillment of any
conditions on exercisability as may be determined by the Committee at the time
of the grant of such Options.  The right to purchase shares of Common
Stock shall be cumulative so that when the right to purchase any shares of
Common Stock has accrued such shares of Common Stock or any part thereof may be
purchased at any time thereafter until the expiration or termination of the
Option.

       

      (d)           Expiration of
Options.  No Option by its terms shall be exercisable after the
expiration of ten (10) years from the date of grant of the Option; provided, however, in the case
of an Incentive Stock Option granted to a person who, at the time such Option is
granted, owns shares of stock of the  Corporation or of any Parent or
Subsidiary possessing more than ten percent (10%) of the total combined voting
power of all classes of shares of stock of the Corporation or of any Parent or
Subsidiary, such Option shall not be exercisable after the expiration of five
(5) years from the date such Option is granted.

       

      (e)           Exercise Upon Death of
Optionee.  Subject to the provisions of Section V(h) hereof, if
an Optionee shall die while employed by or performing services for, or while the
Optionee is a director of, the Corporation or any Parent or Subsidiary, or
within sixty (60) days of the date of the termination of such Optionee’s
employment, directorship or other service relationship (other than for Good
Cause), such Optionee’s estate (or other beneficiary, if so designated in
writing by the Participant) shall have the right, within one (1) year after the
date of death (but in no case after the expiration date of the Option(s)), to
exercise his Option(s) with respect to all or any part of the shares of Common
Stock as to which the deceased Optionee had not exercised his Option at the time
of his death, but only to the extent such Option or Options were exercisable on
the date of his death (or, if provided in an Option Agreement with respect to a
particular Optionee, at the date of exercise determined as if the Optionee died
on such date).

       

      (f)           Exercise Upon Disability of
Optionee.  Subject to the provisions of Section and V(h)
hereof, if the employment, directorship or other service relationship between an
Optionee and the Corporation or any Parent or Subsidiary is terminated by reason
of Disability, such Optionee shall have the right, within one (1) year after the
date of such termination (but in no case after the expiration of the Option(s)),
to exercise his Option(s) with respect to all or any part of the shares of
Common Stock as to which he had not exercised his Option at the time of such
termination, but only to the extent such Option or Options were exercisable on
the date of his termination of employment, directorship or other service
relationship.

       

      (g)           Exercise Upon Optionee’s
Termination of Employment.  With respect to Incentive Stock
Options, if the employment of an Optionee by the Corporation or by any Parent or
Subsidiary is terminated for any reason other than those specified in Sections
V(e) and (f) above or for Good Cause, then the Optionee shall have the right,
within sixty (60) days after the date of such termination, to exercise his
vested Options, and thereafter shall forfeit his rights to exercise all of such
Options.  With respect to any Non-Qualified Stock Options, if the
Optionee’s employment, directorship or other service relationship with the
Corporation or any Parent or Subsidiary is terminated for any reason other than
for death or disability (as governed by Sections V(e) and (f) above) or for Good
Cause, then, except as otherwise expressly provided in an agreement covering an
Option granted to an Optionee, the Optionee shall have the right, within sixty
(60) days after the date of such termination, to exercise his vested Options,
and thereafter shall forfeit his right to exercise all of such
Options.  In each case an Option shall only be
exercisable to the extent it was exercisable on the date of
termination.  In all cases, however, if the termination of the
Optionee’s employment, directorship or other service relationship with the
Corporation or any Parent or Subsidiary is determined by the Committee to have
been for Good Cause or with respect to Options that are not vested on the date
of termination (unless the option grant agreement provided otherwise), then the
Option and all rights thereunder shall terminate on the date of termination of
employment, directorship or other service relationship.

      (h)           Maximum Amount of Incentive
Stock Options.  Each Plan Award under which Incentive Stock
Options are granted shall provide that to the extent the aggregate of the (i)
Fair Market Value of the shares of Common Stock (determined as of the time of
the grant of the Option) subject to such Incentive Stock Option and (ii) fair
market values (determined as of the date(s) of grant of the options) of all
other shares of Common Stock subject to incentive stock options granted to an
Optionee by the Corporation or any Parent or Subsidiary, which are exercisable
for the first time by any individual during any calendar year, exceed(s) one
hundred thousand dollars ($100,000), such excess shares of Common Stock shall
not be deemed to be purchased pursuant to Incentive Stock Options but shall be
deemed to be purchased pursuant to Non-Qualified Stock Options.  The
terms of the immediately preceding sentence shall be applied by taking options
into account in the order in which they are granted.

      The
Committee may from time to time grant stock awards to eligible Participants in
such amounts, on such terms and conditions, and for such consideration,
including no consideration or such minimum consideration as may be required by
law, as it shall determine.  A stock award may be denominated in
Common Stock or other securities, stock-equivalent units, securities or
debentures convertible into Common Stock, or any combination of the foregoing,
and may be paid in Common Stock or other securities, in cash, or in a
combination of Common Stock or other securities and cash, all as determined in
the sole discretion of the Committee.

recapitalization, stock split, reverse stock split, stock dividend or otherwise,
then, the Plan Awards shall, without further action of the Committee, be
adjusted to reflect such event, including as applicable, adjustments to the (i)
maximum number and kind of shares reserved for issuance under Section II hereof,
(ii) number and kind of shares of Common Stock subject to then outstanding Plan
Awards, (iii) the exercise price for each share subject to then outstanding Plan
Awards, and (iv) any other terms of a Plan Award that are affected by the
event.  Notwithstanding the foregoing, (A) each such adjustment with
respect to an Incentive Stock Option shall comply with the rules of Section
424(a) of the Code and (B) in no event shall any adjustment be made which would
render any Incentive Stock Option granted hereunder to be other than an
incentive stock option for purposes of Section 422 of the Code.

      (b)           Discretionary
Adjustments.  In the event of any (i) unusual or nonrecurring
events affecting the Corporation or the financial statements of the Corporation
or any Parent or any Subsidiary, (ii) changes in applicable laws, regulations or
accounting principles affecting the Corporation; or (iii) merger, consolidation,
combination, spin-off or other similar corporate change (other than a
transaction resulting in a Change in Control), then, the Committee may, in the
manner and to the extent that it deems appropriate and equitable to the
Participants and consistent with the terms of the Plan, cause an adjustment to
be made to reflect such event, including as applicable, adjustments to the (A)
maximum number and kind of shares reserved for issuance under Section II hereof,
(B) number and kind of shares of Common Stock subject to then outstanding Plan
Awards, (C) the exercise price for each share subject to then outstanding Plan
Awards, and (D) any other terms of a Plan Award that are affected by the
event.  Notwithstanding the foregoing, (I) each such adjustment with
respect to an Incentive Stock Option shall comply with the rules of Section
424(a) of the Code and (II) in no event shall any adjustment be made which would
render any Incentive Stock Option granted hereunder to be other than an
incentive stock option for purposes of Section 422 of the Code.

       

      (c)           Change in Control
Transactions.  In the event of
any transaction resulting in a Change in Control of the Corporation, and except
as otherwise determined by the Committee at the time the Plan Award is
granted, if no provision is made in connection with the transaction for the
continuation or assumption of outstanding Plan Awards by, or for the
substitution of the equivalent awards of, the surviving or successor entity or a
parent thereof, then all outstanding Plan Awards that are payable in or
convertible into Common Stock under this Plan (including unvested Plan Awards)
shall be fully vested and immediately exercisable in their entirety and shall
terminate upon the effective time of such Change in Control.  In the
event of such termination, the holders of Plan Awards under the Plan will be
permitted, immediately before the Change in Control, to exercise or convert any
or all portions of such Plan Awards under the Plan that are then exercisable or
convertible or which become exercisable or convertible upon or prior to the
effective time of the Change in Control (including upon the acceleration of
vesting of such Plan Awards).

       

       

      SECTION

      MISCELLANEOUS
PROVISIONS

       

      (a)           Administrative
Procedures.  The Committee may establish any procedures
determined by it to be appropriate in discharging its responsibilities under the
Plan.  Subject to the provisions of Section XI hereof, all actions and
decisions of the Committee shall be final.

       

      (b)           Assignment or
Transfer.  No grant or award of any Incentive Stock Option or
any other “derivative security” (as defined by Rule 16a-l(c) promulgated under
the Exchange Act) made under the Plan or any rights or interests therein shall
be assignable or transferable by a Participant except by will or the laws of
descent and distribution or pursuant to a qualified domestic relations
order.  During the lifetime of a Participant Options granted hereunder
shall be exercisable only by the Participant.

       

      (c)           Investment
Representation.  In the case of Plan Awards paid in shares of
Common Stock or other securities, the Committee may require, as a condition of
receiving such securities, that the Participant furnish to the Corporation such
written representations and information as the Committee deems appropriate to
permit the Corporation, in light of theexistence
or nonexistence of an effective registration statement under the Securities Act
to deliver such securities in compliance with the provisions of the Securities
Act.

      (d)           Withholding
Taxes.  The Corporation shall have the right to deduct from all
cash payments hereunder any federal, state, local or foreign taxes required by
law to be withheld with respect to such payments.  In the case of the
issuance or distribution of Common Stock or other securities hereunder, the
Corporation, as a condition of such issuance or distribution, may require the
payment (through withholding from the Participant’s salary, reduction of the
number of shares of Common Stock or other securities to be issued, or otherwise)
of any such taxes.  Subject to the Rules promulgated under Section 16
of the Exchange Act (to the extent applicable), and to the consent of the
Committee, the Participant, may satisfy the withholding obligations by paying to
the Corporation a cash amount equal to the amount required to be withheld or by
tendering to the Corporation a number of shares of Common Stock having a value
equivalent to such cash amount, or by use of any available procedure as
described under Section IV(c) hereof.

       

      (e)           Costs and
Expenses.  The costs and expenses of administering the Plan
shall be borne by the Corporation and shall not be charged against any award nor
to any employee receiving a Plan Award.

       

      (f)           Funding of
Plan.  The Plan shall be unfunded.  The Corporation
shall not be required to segregate any of its assets to assure the payment of
any Plan Award under the Plan.  Neither the Participants nor any other
persons shall have any interest in any fund or in any specific asset or assets
of the Corporation or any other entity by reason of any Plan Award, except to
the extent expressly provided hereunder.  The interests of each
Participant and former Participant hereunder is unsecured and shall be subject
to the general creditors of the Corporation.

       

      (g)           Other Incentive
Plans.  The adoption of the Plan does not preclude the adoption
by appropriate means of any other incentive plan for employees.

       

      (h)           Plurals and
Gender.  Where appearing in the Plan, masculine gender shall
include the feminine and neuter genders, and the singular shall include the
plural, and vice versa, unless the context clearly indicates a different
meaning.

       

      (i)           Headings.  The
headings and sub-headings in this Plan are inserted for the convenience of
reference only and are to be ignored in any construction of the provisions
hereof.

       

      (j)           Severability.  In
case any provision of this Plan shall be held illegal or void, such illegality
or invalidity shall not affect the remaining provisions of this Plan, but shall
be fully severable, and the Plan shall be construed and enforced as if said
illegal or invalid  provisions had never been inserted
herein.

       

      (k)           Payments Due Missing
Persons.  The Corporation shall make a reasonable effort to
locate all persons entitled to benefits under the Plan; however, notwithstanding
any provisions of this Plan to the contrary, if, after a period of one (1) year
from the date such benefit shall be due, any such persons entitled to benefits
have not been located, their rights under the Plan shall stand
suspended.  Before this provision becomes operative, the Corporation
shall send a
certified letter to all such persons at their last known address advising them
that their rights under the Plan shall be suspended.  Subject to all
applicable state laws, any such suspended amounts shall be held by the
Corporation for a period of one (1) additional year and thereafter such amounts
shall be forfeited and thereafter remain the property of the
Corporation.

      (l)           Liability and
Indemnification.  (i)  Neither the Corporation nor
any Parent or Subsidiary shall be responsible in any way for any action or
omission of the Committee, or any other fiduciaries in the performance of their
duties and obligations as set forth in this Plan. Furthermore, neither the
Corporation nor any Parent or Subsidiary shall be responsible for any act or
omission of any of their agents, or with respect to reliance upon advice of
their counsel provided that the Corporation and/or the appropriate Parent or
Subsidiary relied in good faith upon the action of such agent or the advice of
such counsel.

       

      (ii)           Except
for their own gross negligence or willful misconduct regarding the performance
of the dates specifically assigned to them under or their willful breach of the
terms of, this Plan, the Corporation, each Parent and Subsidiary and the
Committee shall be held harmless by the Participants, former Participants,
beneficiaries and their representatives against liability or losses occurring by
reason of any act or omission.  Neither the Corporation, any Parent or
Subsidiary, the Committee, nor any agents, employees, officers, directors or
shareholders of any of them, nor any other person shall have any liability or
responsibility with respect to this Plan, except as expressly provided
herein.

       

      (m)           Incapacity.  If
the Committee shall receive evidence satisfactory to it that a person entitled
to receive payment of any Plan Award is, at the time when
such  benefit becomes payable, a minor, or is physically or mentally
incompetent to receive such Plan Award and to give a valid release thereof, and
that another person or an institution is then maintaining or has custody of such
person and that no guardian, committee or other representative of the estate of
such person shall have been duly appointed, the Committee may make payment of
such Plan Award otherwise payable to such person to such other person or
institution, including a custodian under a Uniform Gifts to Minors Act, or
corresponding legislation (who shall be an adult, a guardian of the minor or a
trust company), and the release of such other person or institution shall be a
valid and complete discharge for the payment of such Plan Award.

       

      (n)           Cooperation of
Parties.  All parties to this Plan and any person claiming any
interest hereunder agree to perform any and all acts and execute any and all
documents and papers which are necessary or desirable for carrying out this Plan
or any of its provisions.

       

      (o)           Governing
Law.  All questions pertaining to the validity, construction
and administration of the Plan shall be determined in accordance with the laws
of the State of New York.

       

      (p)           Nonguarantee of Employment,
Directorship or Other Service Relationships.  Nothing contained
in this Plan shall be construed as a contract of employment between the
Corporation (or any Parent or Subsidiary) and any Participant, as a right of any
Participant to be continued in the employment or other service relationship with
the Corporation (or any Parent or Subsidiary) or to continue or be reelected as
a director of the Corporation (or any
Parent or Subsidiary), or as a limitation on the right of the Corporation (or
any Parent or Subsidiary) to discharge any of its employees or consultants, with
or without cause.

notice relating to this Plan shall be in writing and delivered in person or by
certified mail to the proper address.  All notices to the Corporation

Agreements.  Each Plan Award shall be evidenced by a signed
written agreement between the Corporation and the Participant containing the
terms and conditions of the award and all such Plan Awards shall be subject to
the terms and conditions of the Plan.

specific reasons for the denial.  The Committee shall also furnish
such person at the time with a written notice containing (i) a specific

possible, and an explanation of why such material or information is needed and

submit issues and comments in writing to the Committee.

       

      (d)           Committee’s Final and
Binding Decision.  A final and binding decision shall be made
by the Committee within 60 days of the filing by such person of this request for

representative is necessary or desirable, this period shall be extended for an
additional 60 days.

       

      (e)           Transmittal of
Decision.  The Committee’s decision shall be conveyed to such
person in writing and shall include specific reasons for the decision, written

and shall be issued initially in the form of one or more Restricted Global Securities, which shall be deposited on behalf of the purchasers of the securities represented thereby with the Trustee, at its Corporate Trust Office, as custodian for the
depositary, The Depository Trust Company (“DTC”, and such depositary, or any successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co. (or any successor
thereto), for the accounts of participants in the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. Subject to Section 2.02 hereof, the aggregate principal amount of the Restricted Global
Securities may from time to time be increased or decreased by adjustments made on the records of the Securities Custodian as hereinafter provided, subject in each case to compliance with the Applicable Procedures. 
 (b) Global Securities in General. Each Global Security shall represent such of the outstanding Securities as shall be specified therein and each
shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and 

  

 10 

 
that the aggregate amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect
replacements, exchanges, purchases or conversions of such Securities. Any adjustment of the aggregate principal amount of a Global Security to reflect the amount of any increase or decrease in the amount of outstanding Securities represented thereby
shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 and shall be made on the records of the Trustee and the Depositary. 
 Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depositary or under the Global Security, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and
Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (1) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by the Depositary or (2) impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security. 
 (c) Book Entry Provisions. The Company shall execute and the Trustee shall, in accordance with this Section 2.01(c), authenticate and deliver
initially one or more Global Securities that (1) shall be registered in the name of the Depositary or its nominee, (2) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions and (3) shall
bear legends substantially to the following effect: 
 “UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE
OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF
A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE AND, UNLESS AND UNTIL IT IS
EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE 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 BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.” 
  

 11 

 Section 2.02 Execution and Authentication. 
 (a) The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture is limited, pursuant to the Purchase
Agreement, to $50,000,000 aggregate principal amount ($55,000,000 aggregate principal amount if the Initial Purchaser exercises its over-allotment option in full), except as provided in Sections 2.06 and 2.07. 
 (b) An Officer shall sign the Securities for the Company by manual or facsimile signature. Typographic and other minor errors or defects in any such
facsimile signature shall not affect the validity or enforceability of any Security that has been authenticated and delivered by the Trustee. 
 (c) If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless. 
 (d) A Security shall not be valid until an authorized signatory of the Trustee by manual or facsimile signature signs the certificate of authentication
on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 
 (e) The Trustee
shall authenticate and make available for delivery Securities for original issue in the aggregate principal amount of up to $50,000,000 aggregate principal amount ($55,000,000 aggregate principal amount if the Initial Purchaser exercises its
over-allotment option in full by executing an over-allotment exercise notice and delivering such executed over-allotment exercise notice to the Trustee) upon receipt of a written order or orders of the Company signed by an Officer of the Company (a
“Company Order”). The Company Order shall specify the amount of Securities to be authenticated, shall provide that all such securities will be represented by a Restricted Global Security and the date on which each original issue of
Securities is to be authenticated. 
 (f) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an
authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication
by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. 
 (g)
The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 principal amount and any integral multiple thereof. 
 Section 2.03 Registrar, Paying Agent and Conversion Agent. 
 (a) The Company shall maintain one
or more offices or agencies where Securities may be presented for registration of transfer or for exchange (each, a “Registrar”), one or more offices or agencies where Securities may be presented for payment (each, a “Paying
Agent”), one or more offices or agencies where Securities may be presented for conversion (each, a “Conversion Agent”) and one or more offices or agencies where notices and demands to 

  

 12 

 
or upon the Company in respect of the Securities and this Indenture may be served. The Company will at all times maintain a Paying Agent, Conversion Agent,
Registrar and an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served in the Borough of Manhattan, The City of New York. One of the Registrars (the “Primary
Registrar”) shall keep a register of the Securities and of their transfer and exchange. At the option of the Company, any payment of cash may be made by check mailed to the Holders at their addresses set forth in the register of Holders. The
Company shall provide written notice to the Trustee of any Registrar, Securities Agent, Conversion Agent or Paying Agent that is not also the Trustee. 
 (b) The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, provided that the Agent may be an Affiliate of the Trustee. The agreement shall implement the provisions
of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent, or agent for service
of notices and demands in any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent (except for the purposes of Section 6.01
and Article 10). 
 (c) The Company hereby initially designates the Trustee as Paying Agent, Registrar, Securities Custodian and
Conversion Agent, and designates the Corporate Trust Office of the Trustee as the office or agency of the Company for each of the aforesaid purposes and as the office or agency where notices and demands to or upon the Company in respect of the
Securities and this Indenture shall be served. 
 Section 2.04 Paying Agent to Hold Money in Trust. Prior to 12:00 p.m.
(noon), New York City time, on each due date of the payment of principal of, or interest on, any Securities, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal or interest so becoming due. Subject to
Section 9.02, a Paying Agent shall hold in trust for the benefit of Holders of Securities or the Trustee all money held by the Paying Agent for the payment of principal of, or interest on, the Securities, and shall notify the Trustee of any
failure by the Company (or any other obligor on the Securities) to make any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall, before 12:00 p.m. (noon), New York City time, on each due date of the
principal of, or interest on, any Securities, segregate the money and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time during the
continuance of any Default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no
further liability for the money. 
 Section 2.05 Lists of Holders of Securities. The Trustee shall preserve in as current a form
as is reasonably practicable the most recent list available to it of the names and addresses of Holders of Securities. If the Trustee is not the Primary Registrar, the Company shall furnish to the Trustee on or before each Interest Payment Date and
at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of Securities. 
  

 13 

 Section 2.06 Transfer and Exchange. 
 (a) Subject to compliance with any applicable additional requirements contained in Section 2.12, when a Security is presented to a Registrar with a
request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that
every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate each in the form included in Exhibit A, and completed
in a manner satisfactory to the Registrar and duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security for registration of transfer or exchange
at an office or agency maintained pursuant to Section 2.03, the Company shall execute and the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s request. Any exchange or transfer shall be without
charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto; provided that this sentence shall not apply to any exchange pursuant to
Section 2.10, 2.12(a), 3.05, 4.02(e) or 11.05. 
 (b) Neither the Company, any Registrar nor the Trustee shall be required to exchange
or register a transfer of any Securities or portions thereof in respect of which a Fundamental Change Repurchase Notice (as defined in Section 3.01(c)) has been delivered and not withdrawn by the Holder thereof (except, in the case of the
purchase of a Security in part, the portion thereof not to be purchased). 
 (c) All Securities issued upon any transfer or exchange of
Securities shall be valid obligations of the Company, evidencing the same debt and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. 
 (d) Any Registrar appointed pursuant to Section 2.03 shall provide to the Trustee such information as the Trustee may reasonably require in
connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. 
 (e) Each Holder of a Security agrees
to indemnify and hold harmless the Company and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Security in violation of any provision of this Indenture and/or applicable United States
federal or state securities law. 
 (f) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with
any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or other beneficial owners of interests in any
Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine
substantial compliance as to form with the express requirements hereof. 
  

 14 

 Section 2.07 Replacement Securities. 
 (a) If any mutilated Security is surrendered to the Company, a Registrar or the Trustee, and the Company, a Registrar and the Trustee receive evidence to
their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the applicable Registrar and the Trustee such security or indemnity as will be required by them to save each of them harmless, then, in the
absence of notice to the Company, such Registrar or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute, and upon its written request the Trustee shall authenticate and deliver, in exchange for any
such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding. 
 (b) If any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be purchased by the
Company pursuant to Article 3, or converted pursuant to Article 4, the Company in its discretion may, instead of issuing a new Security, pay, purchase or convert such Security, as the case may be. 
 (c) Upon the issuance of any new Securities under this Section 2.07, the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith. 
 (d) Every new Security issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an
original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder. 
 (e) The provisions of this Section 2.07 are (to the extent
lawful) exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
 Section 2.08 Outstanding Securities. 
 (a) Securities outstanding at any time are all Securities authenticated by the Trustee, except for those canceled by it, those purchased pursuant to Article 3, those converted pursuant to Article 4, those delivered to the Trustee
for cancellation or surrendered for transfer or exchange and those described in this Section 2.08 as not outstanding. 
 (b) If a
Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Company receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. 
 (c) If a Paying Agent (other than the Company or an Affiliate of the Company) holds in respect of the outstanding Securities on a Fundamental Change
Repurchase Date or the Final Maturity Date money sufficient to pay the principal of (including premium, if any) and accrued interest on Securities (or portions thereof) payable on that date, then on and 

  

 15 

 
after such Fundamental Change Repurchase Date or Final Maturity Date, as the case may be, such Securities (or portions thereof, as the case may be) shall
cease to be outstanding and cash interest on them shall cease to accrue. 
 (d) Subject to the restrictions contained in Section 2.09, a
Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. 
 Section 2.09
Treasury Securities. In determining whether the Holders of the required principal amount of Securities have concurred in any notice, direction, waiver or consent, Securities owned by the Company or any other obligor on the Securities or by
any Affiliate of the Company or of such other obligor shall be disregarded, except that, for purposes of determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Securities which a
Responsible Officer of the Trustee with responsibility for this Indenture actually knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee’s right so to act with respect to the Securities and that the pledgee is not the Company or any other obligor on the Securities or any Affiliate of the Company or of such other obligor. 
 Section 2.10 Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and execute, and, upon receipt
of a Company Order, the Trustee shall authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company with the consent of the Trustee considers
appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and deliver definitive Securities in exchange for temporary Securities. 
 Section 2.11 Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Paying Agent
and the Conversion Agent shall forward to the Trustee or its agent any Securities surrendered to them for transfer, exchange, purchase, payment or conversion. The Trustee and no one else shall cancel, in accordance with its standard procedures, all
Securities surrendered for transfer, exchange, purchase, payment, conversion or cancellation and shall dispose of the cancelled Securities in accordance with its customary procedures or deliver the canceled Securities to the Company upon its request
therefor. All Securities which are purchased or otherwise acquired by the Company or any of its Subsidiaries prior to the Final Maturity Date pursuant to Article 3 shall be delivered to the Trustee for cancellation, and the Company may not hold
or resell such Securities or issue any new Securities to replace any such Securities or any Securities that any Holder has converted pursuant to Article 4. 
 Section 2.12 Legend; Additional Transfer and Exchange Requirements. 
 (a) If Securities are
issued upon the transfer, exchange or replacement of Securities subject to restrictions on transfer and bearing the legends set forth on the forms of Securities attached as Exhibit A (collectively, the “Legend”), or if a
request is made to remove the Legend on a Security, the Securities so issued shall bear the Legend, or the Legend shall not be removed, as the case may be, unless there is delivered to the Company and the Registrar such 

  

 16 

 
satisfactory evidence, which shall include an Opinion of Counsel if requested by the Company or such Registrar, as may be reasonably required by the Company
and the Registrar, that neither the Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule 144 under the Securities Act or that such
Securities are not “restricted” within the meaning of Rule 144 under the Securities Act; provided that no such evidence need be supplied in connection with the sale of such Security pursuant to a registration statement that is
effective at the time of such sale. Upon (1) provision of such satisfactory evidence if requested, or (2) notification by the Company to the Trustee and Registrar of the sale of such Security pursuant to a registration statement that is
effective at the time of such sale, the Trustee, at the written direction of the Company, shall authenticate and deliver a Security that does not bear the Legend. If the Legend is removed from the face of a Security and the Security is subsequently
held by an Affiliate of the Company, the Legend shall be reinstated. 
 (b) A Global Security may not be transferred, in whole or in part, to
any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that the foregoing shall not prohibit any transfer of a Security that is issued in exchange for a
Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Notwithstanding any
other provisions of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be made only in accordance with this Section 2.12. 
 (c) Subject to Section 2.12(b) and in compliance with Section 2.12(d), every Security shall be subject to the restrictions on transfer provided in the Legend. Whenever any Restricted Security other than a
Restricted Global Security is presented or surrendered for registration of transfer or in exchange for a Security registered in a name other than that of the Holder, such Security must be accompanied by a certificate in substantially the form set
forth in Exhibit A, dated the date of such surrender and signed by the Holder of such Security, as to compliance with such restrictions on transfer. The Registrar shall not be required to accept for such registration of transfer or
exchange any Security not so accompanied by a properly completed certificate. 
 (d) The restrictions imposed by the Legend upon the
transferability of any Security shall cease and terminate when such Security has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any
successor provision thereto) or, if earlier, the date when the Holder of such Security, other than Holders that are Affiliates of the Company, is able to sell such Security immediately without restriction pursuant to Rule 144(b)(1)(i) under the
Securities Act or any successor Rule thereto. Any Security as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon a surrender of such Security for exchange to the Registrar in
accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer in compliance with Rule 144 or any successor provision, by, if requested by the
Company or the Registrar, an Opinion of Counsel reasonably acceptable to the Company and the Registrar and addressed to the Company and the Registrar, to the effect that the transfer of such Security has been made in compliance with Rule 144 or
such successor provision), be exchanged 

  

 17 

 
for a new Security, of like tenor and aggregate principal amount, which shall not bear the restrictive Legend. The Company shall inform the Trustee of the
effective date of any registration statement registering the offer and sale of the Securities under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the
aforementioned Opinion of Counsel or registration statement. 
 As used in Sections 2.12(c) and (d), the term “transfer”
encompasses any sale, pledge, transfer, hypothecation or other disposition of any Security. 
 (e) The provisions below shall apply only to
Global Securities: 
 (1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary or a
nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for purposes of this Indenture. 
 (2) Notwithstanding any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged in whole or in part for a
Security registered, and no transfer of a Global Security in whole or in part shall be registered in the name of any Person other than the Depositary or one or more nominees thereof; provided that a Global Security may be exchanged for securities
registered in the names of any person designated by the Depositary in the event that (A) 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 after receiving such notice or becoming aware that the Depositary has ceased to be a “clearing
agency,” or (B) an Event of Default has occurred and is continuing with respect to the Securities. Any Global Security exchanged pursuant to subclause (A) above shall be so exchanged in whole and not in part, and any Global Security
exchanged pursuant to subclause (B) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security;
provided, however, that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security. 
 (3) Securities issued in exchange for a Global Security or any portion thereof shall be issued in definitive, fully registered form, without interest
coupons, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear
the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either such Global Security
shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so
exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or
an authorized representative thereof. 
  

 18 

 (4) Subject to clause (6) of this Section 2.12(e), the registered Holder may grant proxies and
otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities. 
 (5) In the event of the occurrence of any of the events specified in clause (2) of this Section 2.12(e), the Company will promptly make
available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons. 
 (6) Neither Agent Members nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or under
any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Security for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or
such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a
holder of any Security. 
 (7) At such time as all interests in a Global Security have been converted, cancelled or exchanged for Securities
in certificated form, such Global Security shall, upon receipt thereof, be cancelled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Securities Custodian, subject to Section 2.11 of
this Indenture. At any time prior to such cancellation, if any interest in a Global Security is converted, canceled or exchanged for Securities in certificated form, the principal amount of such Global Security shall, in accordance with the standing
procedures and instructions existing between the Depositary and the Securities Custodian, be appropriately reduced, and an endorsement shall be made on such Global Security, by the Trustee or the Securities Custodian, at the direction of the
Trustee, to reflect such reduction. 
 (f) Any stock certificate representing Common Stock issued upon conversion of any Security shall bear
a legend in substantially the following form, unless such Common Stock has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or
transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto), or such Common Stock has been issued upon conversion of Securities that have been transferred pursuant to a registration statement that has
been declared effective under the Securities Act or pursuant to Rule 144 under the Securities Act (or any successor provision thereto), or unless otherwise agreed by the Company in writing with written notice thereof to the transfer agent:

 THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), OR ANY STATE SECURITIES LAWS, AND, ACCORDINGLY, 

  

 19 

 
MAY NOT BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH
TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION UNDER THE SECURITIES ACT. 
 BY ITS ACQUISITION HEREOF, THE HOLDER AGREES TO
OFFER, SELL OR OTHERWISE TRANSFER THE COMMON STOCK EVIDENCED HEREBY PRIOR TO THE DATE THAT IS ONE YEAR AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH RASER TECHNOLOGIES, INC. (THE “COMPANY”) OR ANY AFFILIATE
OF THE COMPANY WAS THE OWNER OF THE COMMON STOCK EVIDENCED HEREBY (OR ANY PREDECESSOR OF THE COMMON STOCK EVIDENCED HEREBY) (THE “RESALE RESTRICTION TERMINATION DATE”) ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF,
(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, OR (C) PURSUANT TO ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY’S
AND THE TRANSFER AGENT’S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (C) PRIOR TO THE RESALE RESTRICTION TERMINATION DATE TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATIONS AND/OR OTHER INFORMATION
SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE FOREGOING CASES, TO REQUIRE THAT A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE OTHER SIDE OF THIS CERTIFICATE IS COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRANSFER AGENT. THIS LEGEND
WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE. 
 Any such Common Stock as to which such
restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the foregoing legend set forth therein have been satisfied may, upon surrender of the certificates representing such shares of
Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like number of shares of Common Stock, which shall not bear the restrictive legend
required by this section. The Trustee may reasonably rely on an Opinion of Counsel in order to determine whether the legend is required upon transfer. 
 Section 2.13 CUSIP Numbers. The Company in issuing the Securities may use one or more “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in
notices of purchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a purchase and that
reliance may be placed only on the other identification numbers printed on the Securities, and any such purchase shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the
“CUSIP” numbers. 
 Section 2.14 Calculations. Except as otherwise specifically stated herein or in the Securities, all
calculations to be made in respect of the Securities shall be the obligation of the Company. All calculations made by the Company or its agent as contemplated pursuant to the 

  

 20 

 
terms hereof and of the Securities shall be made in good faith and be final and binding on the Holders absent manifest error. The Company shall provide a
schedule of calculations to the Trustee, and the Trustee shall be entitled to rely upon the accuracy of the calculations by the Company without independent verification. The Trustee shall forward calculations made by the Company to any holder of
Securities upon request. 
 Section 2.15 Computation of Interest. Interest on the Securities shall be computed on the basis of a
360-day year comprised of twelve 30-day months. 
 ARTICLE 3 
 PURCHASE 
 Section 3.01 Repurchase of Securities at Option of the Holder
upon a Fundamental Change. 
 (a) If a Fundamental Change occurs prior to the Final Maturity Date, each Holder of a Security shall have
the right, at the option of the Holder, to require the Company to repurchase for cash all or any portion (in principal amounts of $1,000 and integral multiples thereof) of the Securities of such Holder at the Fundamental Change Repurchase Price, on
the date specified by the Company that is not less than 30 days nor more than 45 days after the date of the Fundamental Change Company Notice pursuant to subsection 3.01(b) (the “Fundamental Change Repurchase Date”). 
 (b) As promptly as practicable following the date on which the Company publicly announces such transaction, but in no event less than 20 days prior to
the anticipated Fundamental Change Effective Date, the Company shall mail a written notice of the Fundamental Change and of the resulting repurchase right to the Trustee, Paying Agent and to each Holder of record of Securities (and to beneficial
owners as required by applicable law) (the “Fundamental Change Company Notice”). The Fundamental Change Company Notice shall include the form of a Fundamental Change Repurchase Notice (as defined below) to be completed by the Holder and

as to which a Fundamental Change Repurchase Notice has been given may be converted into Common Stock pursuant to Article 4 of this Indenture only to the extent that the Fundamental Change Repurchase Notice has been withdrawn in accordance with
the terms of this Indenture; 
 (10) the procedures that the Holder must follow to exercise rights under this Section 3.01; 

(11) the procedures for withdrawing a Fundamental Change Repurchase Notice; 
 (12) that, unless the Company fails to pay such Fundamental Change Repurchase Price, Securities covered by any Fundamental Change Repurchase Notice will

 (13) the CUSIP number of the Securities. 
 At the Company’s request, the Trustee shall give such Fundamental Change Company
Notice in the Company’s name and at the Company’s expense; provided, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. If any of the Securities is in the form of a Global Security,
then the Company shall modify such notice to the extent necessary to accord with the Applicable Procedures relating to the purchase of Global Securities. 
 (c) A Holder may exercise its rights specified in Section 3.01(a) upon delivery of a written notice (which shall be in substantially the form attached as Exhibit A under the heading “Fundamental
Change Repurchase Notice” and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in
accordance with the Depositary’s Applicable Procedures) of the exercise of such rights (a “Fundamental Change Repurchase Notice”) to the Company or any Paying Agent at any time prior to the close of business on the Business Day next
preceding the Fundamental Change Repurchase Date, subject to extension to comply with applicable law. 
 (1) The Fundamental Change
Repurchase Notice shall state: (A) the certificate number (if such Security is held other than in global form) of the Security which the Holder will deliver to be purchased (or, if the Security is held in global form, any other items required
to comply with the Applicable Procedures), (B) the portion of the principal amount of the Security which the Holder will deliver to be purchased, which must be $1,000 or an integral multiple of $1,000, and (C) that such Security shall be

 (2) The delivery of a Security for which a Fundamental Change Repurchase Notice has been timely
delivered to any Paying Agent and not validly withdrawn prior to, on or after the Fundamental Change Repurchase Date (together with all necessary endorsements) at the office of such Paying Agent shall be a condition to the receipt by the Holder of
the Fundamental Change Repurchase Price therefor. 
 (3) The Company shall only be obliged to purchase, pursuant to this Section 3.01,
a portion of a Security if the principal amount of such portion is $1,000 or an integral multiple of $1,000 (provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of such Security).

 (4) Notwithstanding anything herein to the contrary, any Holder delivering to a Paying Agent the Fundamental Change Repurchase Notice

 (5) A Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written withdrawal thereof.

 (6) Anything herein to the contrary notwithstanding, in the case of Global Securities, any Fundamental Change Repurchase Notice may be
delivered or withdrawn and such Securities may be surrendered or delivered for purchase in accordance with the Applicable Procedures as in effect from time to time. 
 Section 3.02 Effect of Fundamental Change Repurchase Notice. 
 (a) Upon receipt by any Paying
Agent of a properly completed Fundamental Change Repurchase Notice from a Holder, the Holder of the Security in respect of which such Fundamental Change Repurchase Notice was given shall (unless such Fundamental Change Repurchase Notice is withdrawn
as specified in Section 3.02(b)) thereafter be entitled to receive the Fundamental Change Repurchase Price with respect to such Security, subject to the occurrence of the Fundamental Change Effective Date and an absence of an Event of Default,
or a continuation thereof (other than a Default in the payment of the Fundamental Change Repurchase Price). Such Fundamental Change Repurchase Price shall be paid to such Holder promptly following the later of (1) the Fundamental Change
Repurchase Date (provided that the conditions in Section 3.01 have been satisfied) and (2) the time of delivery of such Security to a Paying Agent by the Holder thereof in the manner required by Section 3.01(c), together with
necessary endorsements. Securities in respect of which a Fundamental Change Repurchase Notice has been given by the Holder thereof may not be converted into shares of Common Stock pursuant to Article 4 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 3.02(b) with respect to the Securities to be converted. 
  

 23 

 (b) A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice (which may be
delivered by mail, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered by other means in accordance with the Applicable Procedures) of withdrawal delivered by
the Holder to a Paying Agent at any time prior to the close of business on the Business Day immediately prior to the Fundamental Change Repurchase Date, specifying (1) the principal amount of the Security or portion thereof (which must be a
principal amount of $1,000 or an integral multiple of $1,000 in excess thereof) with respect to which such notice of withdrawal is being submitted, (2) if Certificated Securities have been issued, the certificate number of the Security being
withdrawn in whole or in withdrawable part (or if the Securities are not certificated, such written notice must comply with the Applicable Procedures) and (3) the portion of the principal amount of the Security that will remain subject to the
Fundamental Change Repurchase Notice, which portion must be a principal amount of $1,000 or an integral multiple thereof. 
 Section 3.03 Deposit of Fundamental Change Repurchase Price. 
 (a) On or before 12:00 p.m. (noon) New York City
time on the Business Day following the applicable Fundamental Change Repurchase Date, the Company shall deposit with the Trustee or with a Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate
and hold in trust as provided in Section 2.04) an amount of money (in immediately available funds), sufficient to pay the aggregate Fundamental Change Repurchase Price of all the Securities or portions thereof that are to be purchased as of
such Fundamental Change Repurchase Date. 
 (b) If a Paying Agent or the Trustee holds, in accordance with the terms hereof, money sufficient
to pay the Fundamental Change Repurchase Price of any Security for which a Fundamental Change Repurchase Notice has been tendered and not withdrawn in accordance with this Indenture then, on the Business Day following the applicable Fundamental
Change Repurchase Date, such Security will cease to be outstanding, whether or not the Security is delivered to the Paying Agent or the Trustee, and interest and Liquidated Damages, if any, shall cease to accrue, and the rights of the Holder in
respect of the Security shall terminate (other than the right to receive the Fundamental Change Repurchase Price as aforesaid). The Company shall publicly announce the principal amount of Securities repurchased on or as soon as practicable after the
Fundamental Change Repurchase Date. 
 (c) The Paying Agent will promptly return to the respective Holders thereof any Securities with
respect to which a Fundamental Change Repurchase Notice has been withdrawn in compliance with this Indenture. 
 (d) If a Fundamental Change
Repurchase Date falls after a Regular Record Date and on or before the related Interest Payment Date, then interest on the Securities payable on such Interest Payment Date will be payable to the Holders in whose names the Securities are registered
at the close of business on such Regular Record Date. 
 Section 3.04 Repayment to the Company. To the extent that the aggregate
amount of cash deposited by the Company pursuant to Section 3.03 exceeds the aggregate Fundamental 

  

 24 

 
Change Repurchase Price of the Securities or portions thereof that the Company is obligated to purchase, then promptly after the Fundamental Change
Repurchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the Company. 
 Section 3.05
Securities Purchased in Part. Any Security that is to be purchased only in part shall be surrendered at the office of a Paying Agent, and promptly after the Fundamental Change Repurchase Date, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of such authorized denomination or denominations as may be requested by such Holder (which must be equal to $1,000 principal amount or any
integral thereof), in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased. 
 Section 3.06 Compliance with Securities Laws upon Purchase of Securities. In connection with any offer to purchase of Securities under Section 3.01, the Company shall (a) comply with
Rule 13e-4 and Rule 14e-1 (or any successor to either such Rule), and any other tender offer rules, if applicable, under the Exchange Act, (b) file the related Schedule TO (or any successor or similar schedule, form or report) if
required under the Exchange Act, and (c) otherwise comply with all federal and state securities laws in connection with such offer to purchase or purchase of Securities, all so as to permit the rights of the Holders and obligations of the
Company under Sections 3.01 through 3.04 to be exercised in the time and in the manner specified therein. To the extent that compliance with any such laws, rules and regulations would result in a conflict with any of the terms hereof, this Indenture
is hereby modified to the extent required for the Company to comply with such laws, rules and regulations. 
 Section 3.07 Purchase
of Securities in Open Market. The Company may surrender any Security purchased by the Company pursuant to this Article 3 to the Trustee for cancellation. Any securities surrendered to the Trustee for cancellation may not be reissued or
resold by the Company and will be canceled promptly in accordance with Section 2.11. The Company may repurchase Securities in the open market, by tender at any price or by negotiated transactions. 
 ARTICLE 4 
 CONVERSION

 Section 4.01 Conversion Privilege and Conversion Rate. 
 (a) Any Security or portion thereof that is an integral multiple of $1,000 principal amount may be converted by the Holder thereof in accordance with the
provisions of this Article 4. Upon conversion, Holders shall be entitled to receive shares of Common Stock determined in the manner provided in Section 4.13. Securities may be converted prior to the close of business on the second Business Day
preceding the Final Maturity Date at the Conversion Rate in effect at the time of such conversion. 
 (b) Provisions of this Indenture that
apply to conversion of all of a Security also apply to conversion of a portion of a Security. 
 (c) A Holder of Securities is not entitled
to any rights of a holder of Common Stock until such Holder has converted its Securities into Common Stock, and only to the extent such Securities are deemed to have been converted into Common Stock pursuant to this Article 4. 
  

 25 

 (d) The Conversion Rate shall be adjusted in certain instances as provided in Section 4.01(e) and
Section 4.06. 
 (e) If there shall have occurred a Fundamental Change prior to the Final Maturity Date as a result of a transaction
described in clauses (i), (ii) or (iv) of the definition of the term “Change of Control”, the Company shall pay a “Make Whole Premium” to the Holders of the Securities who convert their Securities during the period
beginning 10 Trading Days before the date the Company publicly announces as the anticipated Fundamental Change Effective Date and ending at the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date or 10
Trading Days after the Fundamental Change Effective Date, if later, by increasing the Conversion Rate for such Securities. The number of additional shares of Common Stock per $1,000 principal amount of Securities constituting the Make Whole Premium
shall be determined by the Company by reference to the table below, based on the Fundamental Change Effective Date and the Stock Price applicable to the Fundamental Change; provided that if the Stock Price or Fundamental Change Effective Date are
not set forth on the table: (i) if the actual Stock Price on the Fundamental Change Effective Date is between two Stock Prices on the table or the actual Fundamental Change Effective Date is between two Fundamental Change Effective Dates on the
table, the Make Whole Premium will be determined by a straight-line interpolation between the Make Whole Premiums set forth for the two Stock Prices and the two Fundamental Change Effective Dates on the table based on a 365-day year, as applicable,
(ii) if the Stock Price on the Fundamental Change Effective Date exceeds $50.00 per share, subject to adjustment as set forth herein, no Make Whole Premium will be paid, and (iii) if the Stock Price on the Fundamental Change Effective Date
is less than $7.69 per share, subject to adjustment as set forth herein, no Make Whole Premium will be paid.

 The Stock Prices set forth in the first column of the table above will be adjusted as of any date on
which the Conversion Rate of the Securities is adjusted pursuant to Section 4.06 hereof. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment multiplied by a fraction, the numerator of which is
the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of additional shares set forth in the table above will be adjusted in
the same manner as the Conversion Rate as set forth in Section 4.06 hereof, other than as a result of an adjustment of the Conversion Rate by adding the Make Whole Premium as described above. 
 Notwithstanding the foregoing, in no event will the Conversion Rate exceed 130.0390 per $1,000 principal amount, subject to adjustment in the same
manner as the Conversion Rate as set forth in subsections (a) through (e) of Section 4.06. 
 The additional shares of Common
Stock issuable pursuant to this Section 4.01(e) shall be delivered upon the later of (i) the settlement date for the conversion and (ii) promptly following the Fundamental Change Effective Date. 
 (f) By delivering the number of shares of Common Stock issuable on conversion to the Trustee, or to the Conversion Agent, if the Conversion Agent is
other than the Trustee, the Company will be deemed to have satisfied its obligation to pay the principal amount of the Securities so converted and its obligation to pay accrued and unpaid interest, and Liquidated Damages if any, attributable to the
period from the most recent Interest Payment Date through the Conversion Date (which amount will be deemed paid in full rather than cancelled, extinguished or forfeited). 
 (g) The Trustee may conclusively rely on the Company’s calculations of the Make Whole Premium. 
 (h)
Securities in respect of which a Fundamental Change Repurchase Notice has been delivered, if otherwise convertible pursuant to this Article 4, may not be surrendered for conversion pursuant to this Article 4 prior to a valid withdrawal of such
Fundamental Change Purchase Notice, in accordance with the provisions of Article 3. 
 (i) The conversion rights pursuant to this Article 4
shall commence on the Issue Date of the Securities and expire at the close of business on the second Business Day immediately preceding the Final Maturity Date. 
 Section 4.02 Conversion Procedure. 
 (a) To convert a Security, a Holder must (1) complete
and manually sign the conversion notice on the back of the Security (which shall be substantially in the form set forth in the form of Security attached as Exhibit A under the heading “Conversion Notice”) and deliver such notice to a
Conversion Agent, (2) surrender the Security to a Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, (4) pay an amount equal to the interest payable on the next Interest
Payment Date if and as required by Section 4.02(c) and (5) pay all transfer or similar taxes, if required pursuant to Section 4.04. The date on which the Holder satisfies all of those requirements is the “Conversion 

  

 27 

 
Date.” Upon the conversion of a Security, the Company shall deliver the shares of Common Stock determined in accordance with Section 4.13,
(A) in the case of conversions prior to the 52nd Trading Day prior to the Final Maturity Date, on the third Business Day after the date a
Holder has fulfilled all requirements herein for conversion, and (B) in the case of conversions on or after the 52nd Trading Day prior to the
Final Maturity Date, on the Final Maturity Date. Anything herein to the contrary notwithstanding, in the case of Global Securities, conversion notices may be delivered and such Securities may be surrendered for conversion in accordance with the
Applicable Procedures as in effect from time to time. 
 (b) The person in whose name the shares of Common Stock are issuable upon conversion
shall be deemed to be a holder of record of such Common Stock on the Conversion Date; provided, however, that no surrender of a Security on any Conversion Date when the stock transfer books of the Company shall be closed shall be effective to
constitute the person or persons entitled to receive the shares of Common Stock upon conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the person or persons
entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; provided further that such conversion shall be
at the Conversion Rate in effect on the Conversion Date as if the stock transfer books of the Company had not been closed. Upon conversion of a Security, such person shall no longer be a Holder of such Security. Except as set forth in this
Indenture, no payment or adjustment will be made for dividends or distributions declared or made on shares of Common Stock issued upon conversion of a Security prior to the issuance of such shares. 
 (c) Holders of Securities surrendered for conversion (in whole or in part) during the period from the close of business on any Regular Record Date to the
opening of business on the next succeeding Interest Payment Date will receive the semi-annual interest payable on such Securities on the corresponding Interest Payment Date notwithstanding the conversion, and such interest shall be payable on the
corresponding Interest Payment Date to the Holder of such Securities as of the close of business on the Regular Record Date. Upon surrender of any such Securities for conversion after the close of business on such Regular Record Date, such
Securities shall also be accompanied by payment by the Holders of such Securities in funds to the Conversion Agent acceptable to the Company of an amount equal to the interest payable on such corresponding Interest Payment Date; provided that
no such payment need be made: (1) in connection with a conversion following the Regular Record Date preceding the Final Maturity Date; (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record
Date and on or prior to the corresponding Interest Payment Date, in which case accrued and unpaid interest to, but excluding, the Fundamental Change Repurchase Date shall be paid on such Interest Payment Date to the record holder as of the Regular
Record Date. Each payment of cash interest on the Securities will include interest accrued for the period commencing on and including the immediately preceding Interest Payment Date (or, if no interest has been paid, the date the Securities are
originally issued) through the day before the applicable interest payment date (or Fundamental Change Repurchase Date); or (3) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such
Security. Except as otherwise provided in this Section 4.02(c), no payment or adjustment will be made for accrued and unpaid interest on a converted Security. Accrued interest will be deemed paid by the shares of Common Stock (or any cash in
lieu 

  

 28 

 
thereof) received by the Holder upon conversion. Delivery to the Holder of the full number of shares of Common Stock into which the Security is convertible,
together with any cash payment in lieu of such Holder’s fractional shares, shall be deemed to satisfy the Company’s obligation to pay the principal amount of the Security and to pay accrued and unpaid interest on the Security. Accrued and
unpaid interest shall be deemed paid in full, rather than cancelled, extinguished or forfeited. The Company shall not be required to convert any Securities which are surrendered for conversion without payment of interest as required by this
Section 4.02(c). 
 (d) In the case of any Security which is converted in part only, upon such conversion the Company shall execute and
the Trustee shall authenticate and deliver to the Holder thereof, without service charge, a new Security or Securities of authorized denominations in an aggregate principal amount equal to the, and in exchange for, unconverted portion of the
principal amount of such Security. A Security may be converted in part, but only if the principal amount of such part is an integral multiple of $1,000 and the principal amount of such Security to remain outstanding after such conversion is equal to
$1,000 or any integral multiple of $1,000 in excess thereof. 
 Section 4.03
Fractional Shares. The Company will not issue fractional shares of Common Stock upon conversion of Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares that shall
be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. In lieu of any fractional shares, the Company shall pay:
(i) in the case of conversions prior to the 52nd Trading Day prior to the Final Maturity Date, an amount in cash equal to the applicable
portion of the Closing Sale Price of the Common Stock for the Trading Day immediately preceding the conversion date, rounding to the nearest whole cent; or (ii) in the case of conversions on or after the 52nd Trading Day prior to the Final Maturity Date, an amount in cash equal to the applicable portion of the Volume Weighted Average Price of the Common Stock for the last Trading Day of
the Maturity Conversion Reference Period, rounding to the nearest whole cent. 
 Section 4.04 Taxes on Conversion. If a Holder
converts a Security, the Holder shall pay any transfer, stamp or similar taxes or duties related to the issue or delivery of shares of Common Stock upon such conversion. The Holder shall also pay any such tax with respect to cash received in lieu of
fractional shares. In addition, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to deliver the certificate representing
the Common Stock being issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder’s name. Nothing
herein shall preclude any tax withholding required by law or regulation. 
 Section 4.05 Company to Provide Stock. 
 (a) The Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve, out of its authorized but
unissued Common Stock, a sufficient number of shares of Common Stock to permit the conversion of all outstanding Securities into shares of Common Stock. 
  

 29 

 (b) All shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares,
shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive or similar rights and free of any lien or adverse claim as the result of any action by the Company. 
 (c) The Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock
upon conversion of Securities. 
 Section 4.06 Adjustment of Conversion Rate. 
 The Conversion Rate shall be adjusted from time to time by the Company as follows: 
 (a) If the Company issues Common Stock as a dividend or distribution on Common Stock to all holders of Common Stock, or if the Company effects a share
split or share combination, the Conversion Rate will be adjusted based on the following formula: 
  

			
	 CR1 =
	 	CR0 x OS1/OS0
		
	where	 	
		
	CR0 =	 	the Conversion Rate in effect immediately prior to the adjustment relating to such event;
		
	CR1 =	 	the new Conversion Rate in effect taking such event into account;
		
	OS0 =	 	the number of shares of Common Stock outstanding immediately prior to such event; and
		
	OS1 =	 	the number of shares of Common Stock outstanding immediately after such event.

 Any adjustment made pursuant to this Section 4.06(a) shall become effective on the date that
is immediately after (x) the date fixed for the determination of stockholders entitled to receive such dividend or other distribution or (y) the date on which such split or combination becomes effective, as applicable. If any dividend or
distribution described in this Section 4.06(a) is declared but not so paid or made, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

 (b) If the Company issues to all holders of Common Stock any rights, warrants, options or other securities entitling them for a period of
not more than 45 days after the date of issuance thereof to subscribe for or purchase Common Stock, or if the Company issues to all holders of Common Stock securities convertible into Common Stock for a period of not more than 45 days after the date
of issuance thereof, in either case at an exercise price per share of Common Stock or a conversion price per share of Common Stock less than the Closing Sale Price of the Common Stock on the Business Day immediately preceding the time of
announcement of such issuance, the Conversion Rate will be adjusted based on the following formula: 
  

			
	CR1 =	 	CR0 x (OS0+X)/(OS0+Y)

  

 30 

			
	where	 	
		
	CR0 =	 	the Conversion Rate in effect immediately prior to the adjustment relating to such event;
		
	CR1 =	 	the new Conversion Rate taking such event into account;
		
	OS0 =	 	the number of shares of Common Stock outstanding immediately prior to such event;
		
	X =	 	the total number of shares of Common Stock issuable pursuant to such rights, warrants, options, other securities or convertible securities; and
		
	Y =	 	the number of shares of Common Stock equal to the quotient of (A) the aggregate price payable to exercise such rights, warrants, options, other securities or convertible securities and
(B) the average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Days prior to the Business Day immediately preceding the date of announcement for the issuance of such rights, warrants, options, other securities or
convertible securities.

 For purposes of this Section 4.06(b), in determining whether any rights, warrants, options,
other securities or convertible securities entitle the holders to subscribe for or purchase, or exercise a conversion right for, Common Stock at less than the applicable Closing Sale Price of the Common Stock, and in determining the aggregate
exercise or conversion price payable for such Common Stock, there shall be taken into account any consideration received by the Company for such rights, warrants, options, other securities or convertible securities and any amount payable on exercise
or conversion thereof, with the value of such consideration, if other than cash, to be determined by the Board of Directors of the Company. Any adjustment made pursuant to this Section 4.06(b) shall become effective on the date that is
immediately after the date fixed for the determination of shareholders entitled to receive such rights, warrants, options, other securities or convertible securities. If any right, warrant, option, other security or convertible security described in
this Section 4.06(b) is not exercised or converted prior to the expiration of the exercisability or convertibility thereof, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such right, warrant,
option, other security or convertible security had not been so issued. 
 (c) If the Company distributes capital stock, evidences of
indebtedness or other assets or property of the Company to all holders of Common Stock, excluding: 
 (1) dividends,
distributions, rights, warrants, options, other securities or convertible securities referred to in Section 4.06(a) or (b) above, 
  

 31 

			
	(2)	 	dividends or distributions paid exclusively in cash, and
		
	(3)	 	Spin-Offs described below in this Section 4.06(c),

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

			
	 CR1 =
	 	CR0 x SP0/(SP0-FMV)
		
	where	 	
		
	CR0 =	 	the Conversion Rate in effect immediately prior to the adjustment relating to such event;
		
	CR1 =	 	the new Conversion Rate taking such event into account;
		
	SP0 =	 	the Closing Sale Price of the Common Stock over the 10 consecutive trading days ending on the Trading Day immediately preceding the ex-dividend date for such distribution; and
		
	FMV =	 	the fair market value (as determined in good faith by the Board of Directors of the Company) of the capital stock, evidences of indebtedness, assets or property distributed with respect to each
outstanding share of Common Stock on the ex-dividend date for such distribution.

 An adjustment to the Conversion Rate made pursuant to this paragraph shall be made successively whenever any such
distribution is made and shall become effective on the ex-dividend date for such distribution. The “ex-dividend date” is the first date upon which a sale of the Common Stock does not automatically transfer the right to receive the relevant
distribution from the seller of the Common Stock to its buyer. 
 If the Company distributes to all holders of Common Stock
capital stock of any class or series, or similar equity interest, of or relating to a subsidiary or other business unit of the Company (a “Spin-Off”), the Conversion Rate in effect immediately before the close of business on the date fixed
for determination of holders of Common Stock entitled to receive such distribution will be adjusted based on the following formula: 
  

			
	 CR1 =
	 	CR0 x (FMV0+MP0)/MP0
		
	where	 	
		
	CR0 =	 	the Conversion Rate in effect immediately prior to the adjustment relating to such event;
		
	CR1 =	 	the new Conversion Rate taking such event into account;
		
	FMV0 =	 	the average of the Closing Sale Prices of the capital stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first 10
consecutive Trading Days after the effective date of the Spin-Off; and

  

 32 

			
	 MP0 =
	 	the average of the Closing Sale Prices of the Common Stock over the first 10 consecutive Trading Days after the effective date of the Spin-Off.

 An adjustment to the Conversion Rate made pursuant to this paragraph will occur on
the 10th Trading Day from and including the effective date of the Spin-Off; provided that in respect of any conversion within the 10 consecutive Trading Days immediately following the effective date of any Spin Off, references with respect to 10
consecutive Trading Days shall be deemed replaced with such lesser number of consecutive Trading Days as have elapsed 
 If any such dividend
or distribution described in this Section 4.06(c) is declared but not paid or made, the new Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

 (d) If the Company pays or makes any dividend or distribution consisting exclusively of cash to all holders of Common Stock, the
Conversion Rate will be adjusted based on the following formula: 
  
  

			
	 CR1 =
	 	CR0 x (SP0)/(SP0-C)
		
	where	 	
		
	CR0 =	 	the Conversion Rate in effect immediately prior to the adjustment relating to such event;
		
	CR1 =	 	the new Conversion Rate taking such event into account;
		
	SP0 =	 	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Days ending on the Trading Day immediately preceding the ex-dividend date for such
distribution;
		
	C =	 	the amount in cash per share of Common Stock that the Company distributes to holders of Common Stock.

 An adjustment to the Conversion Rate made pursuant to this Section 4.06(d) shall become
effective on the ex-dividend date for such dividend or distribution. If any dividend or distribution described in this Section 4.06(d) is declared but not so paid or made, the new Conversion Rate shall be readjusted to the Conversion Rate that
would then be in effect if such dividend or distribution had not been declared. 
 (e) If the Company or any of its subsidiaries makes a
payment in respect of a tender offer or exchange offer for Common Stock to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Closing Sale Price of the Common Stock on the
Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Time”), the Conversion Rate will be adjusted based on the following formula: 
  

			
	 CR1 =
	 	CR0 x (AC + (SP1 x OS1))/(SP1 x
OS0)

  

 33 

			
	where	 	
		
	CR0 =	 	the Conversion Rate in effect immediately prior to the adjustment relating to such event;
		
	CR1 =	 	the new Conversion Rate taking such event into account;
		
	AC =	 	the aggregate value of all cash and any other consideration (as determined by the Board of Directors of the Company) paid or payable for Common Stock purchased in such tender or exchange offer;

		
	OS0 =	 	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires;
		
	OS1 =	 	the number of shares of Common Stock outstanding immediately after such tender or exchange offer expires (after giving effect to the purchase or exchange of shares pursuant to such tender or
exchange offer); and
		
	SP1 =	 	the average of the Closing Sale Prices of Common Stock for the 10 consecutive Trading Days commencing on the Trading Day next succeeding the date such tender or exchange offer
expires.

 If the application of the foregoing formula
would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made. Any adjustment to the Conversion Rate made pursuant to this Section 4.06(e) shall become effective on the date immediately following the
determination of the average of the Closing Sale Prices of Common Stock for purposes of SP1 above. If the Company or one of its subsidiaries is
obligated to purchase Common Stock pursuant to any such tender or exchange offer but the Company or the relevant subsidiary is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the new
Conversion Rate shall be readjusted to be the Conversion Rate that would be in effect if such tender or exchange offer had not been made. 
 (f) Notwithstanding subsections (a) through (e) of this Section 4.06, in no event shall the Conversion Rate as adjusted in accordance with the foregoing exceed 130.0390 shares per $1,000 principal amount of Securities, other
than on account of adjustments to the Conversion Rate in the manner set forth in subsections (a) through (e) of this Section 4.06. 
 (g) If the Company has in effect a rights plan while any Securities remain outstanding, Holders will receive, upon a conversion of Securities in respect of which the Company is required to deliver shares of Common Stock, in addition to such
shares of Common Stock, rights under the Company’s stockholder rights plan unless, prior to conversion, the rights have expired, terminated or been redeemed or unless the rights have separated from the Common Stock. If the rights provided for
in the rights plan adopted by the Company have separated from 

  

 34 

 
the Common Stock in accordance with the provisions of the applicable stockholder rights agreement so that Holders would not be entitled to receive any rights
in respect of Common Stock, if any, that the Company is required to deliver upon conversion of Securities, the Conversion Rate will be adjusted at the time of separation as if the Company had distributed to all holders of Common Stock, capital
stock, evidences of indebtedness or other assets or property pursuant to Section 4.06(c) above, subject to readjustment upon the subsequent expiration, termination or redemption of the rights. 
 (h) For purposes of this Section 4.06, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of
the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 Section 4.07 No Adjustment. 
 (a) No adjustment in the Conversion Rate shall be required if Holders may participate in
the transactions set forth in Section 4.06 above (to the same extent as if the Securities had been converted into Common Stock immediately prior to such transactions) without converting the Securities held by such Holders. 
 (b) No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion
Rate as last adjusted; provided, however, that any adjustments which would be required to be made but for this Section 4.07(b) shall be carried forward and taken into account in any subsequent adjustment. The Company shall adjust for any carry
forward amount upon conversion regardless of the 1% threshold. All calculations under this Article 4 shall be made to the nearest cent or to the nearest one-ten thousandth of a share, as the case may be, with one half cent and 0.00005 of a
share, respectively, being rounded upward. 
 (c) Notwithstanding anything to the contrary contained herein, in addition to the other events
set forth herein on account of which no adjustment to the Conversion Rate shall be made, the applicable Conversion Rate shall not be adjusted for: (i) the issuance of any Common Stock pursuant to any present or future plan providing for the
reinvestment of dividends or interest payable on securities of the Company and the investment of additional optional amounts in Common Stock under any plan; (ii) the issuance of any shares of Common Stock or options or rights to purchase those
shares pursuant to any present or future employee, director or consultant benefit plan, employee agreement or arrangement or program of the Company; (iii) the issuance of any shares of Common Stock pursuant to any option, warrant, right, or
exercisable, exchangeable or convertible security outstanding as of the date the Securities were first issued; (iv) a change in the par value of the Common Stock; (v) accumulated and unpaid dividends or distributions; or (vi) as a
result of a tender offer solely to holders of fewer than 100 shares of Common Stock. 
 (d) To the extent that the Securities become
convertible into the right to receive cash, no adjustment need be made thereafter as to the cash. 
  

 35 

 Section 4.08 Notice of Adjustment. Whenever the Conversion Rate or conversion privilege is
required to be adjusted pursuant to this Indenture, the Company shall promptly mail to Holders a notice of the adjustment and file with the Trustee an Officer’s Certificate briefly stating the facts requiring the adjustment and the manner of
computing it. Failure to mail such notice or any defect therein shall not affect the validity of any such adjustment. Unless and until the Trustee shall receive an Officer’s Certificate setting forth an adjustment of the Conversion Rate, the
Trustee may assume without inquiry that the Conversion Rate has not been adjusted and that the last Conversion Rate of which it has knowledge remains in effect. 
 Section 4.09 Notice of Certain Transactions. In the event that there is a dissolution or liquidation of the Company, the Company shall mail to Holders and file with the Trustee a notice stating the
proposed effective date. The Company shall mail such notice at least 10 days before such proposed effective date. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in this
Section 4.09. 
 Section 4.10 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale. If any of the
following events occur (each, a “Business Combination”): 
 (1) any recapitalization, reclassification or change of the Common
Stock, other than (a) a change in par value, or from par value to no par value, or from no par value to par value, or (b) changes resulting from a subdivision or a combination, 
 (2) a consolidation, merger or combination of the Company with another Person, 
 (3) a sale, conveyance or lease to another corporation of all or substantially all of the property and assets of the Company, other than one or more of
the Company’s Subsidiaries, or 
 (4) any statutory share exchange of the Company with another Person, 
 in each case as a result of which holders of Common Stock are entitled to receive stock, other securities, other property or assets (including cash or any combination
thereof) with respect to or in exchange for Common Stock, the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of
execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that the Holders of the Securities then outstanding will be entitled thereafter to convert such Securities into the kind and amount of
shares of stock, other securities or other property or assets (including cash or any combination thereof) which holders of Common Stock would have owned or are entitled to receive in respect of each share of Common Stock upon such Business
Combination had such Securities been converted into Common Stock immediately prior to such Business Combination, except that such Holders will not receive the Make Whole Premium if such Holders do not convert their Securities “in connection
with” the relevant Fundamental Change. A conversion of the Securities by a Holder will be deemed for these purposes to be “in connection with” a Fundamental Change if the notice of such conversion is provided in compliance with
Section 4.02(a) to the Conversion Agent on or subsequent to the date 10 Trading Days prior to 

  

 36 

 
the date announced by the Company as the anticipated Fundamental Change Effective Date but before the close of business on the Business Day immediately
preceding the related Fundamental Change Repurchase Date. In the event holders of Common Stock have the opportunity to elect the form of consideration to be received in such Business Combination, the Securities will be convertible into the weighted
average of the kind and amount of consideration received by the holders of the Common Stock that affirmatively make such an election. The Company may not become a party to any such transaction unless its terms are consistent with this
Section 4.10. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 4. If, in the case of any such Business Combination, the
stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such
Business Combination, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably
consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the repurchase rights set forth in Article 3 hereof. Notwithstanding anything contained in this Section, and for the avoidance of
doubt, this Section shall not affect the right of a Holder to convert its Securities into shares of Common Stock prior to the effective date of the Business Combination. 
 Section 4.11 Trustee’s Disclaimer. 
 (a) The Trustee shall have no duty to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of
any such adjustment, and shall be protected in relying upon, an Officer’s Certificate and/or an Opinion of Counsel, including the Officer’s Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant
to Section 4.08. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the Company’s failure to comply with any
provisions of this Article 4. 
 (b) The Trustee shall not be under any responsibility to determine the correctness of any provisions
contained in any supplemental indenture executed pursuant to Section 4.10, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officer’s Certificate and Opinion of Counsel,
with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 12.04. 
 Section 4.12
Voluntary Increase. The Company may also, from time to time, to the extent permitted by applicable law, increase the Conversion Rate by any amount for any period of at least 20 days if the Company has determined that such increase would be in
the best interests of the Company. If the Company makes such determination, it will be conclusive and the Company will mail to holders of the Securities a notice of the increased Conversion Rate and the period during which it will be in effect at
least fifteen (15) days prior to the date the increased Conversion Rate takes effect in accordance with applicable law. The Company may also make such an increase to the Conversion Rate as the Board of Directors determines would avoid or
diminish U.S. federal income tax to holders of shares of Common Stock in connection with a dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for U.S. federal income tax purposes.

 Section 4.13 Settlement Upon Conversion. 
 (a) Upon conversion of any Security prior to the 52nd Trading Day immediately preceding the Final Maturity Date, Holders surrendering Securities for conversion shall be entitled to receive, for each $1,000 principal amount of
Securities surrendered for conversion, a number of shares of Common Stock equal to the applicable Conversion Rate. Upon conversion of any Security on or after the 52nd Trading Day immediately preceding the Final Maturity Date, Holders surrendering Securities for conversion shall be entitled to receive, for each $1,000 principal amount of Securities surrendered for conversion:
(A) a number of shares of Common Stock equal to the sum of the Daily Principal Share Amounts for each of the 50 consecutive Trading Days in the Maturity Conversion Reference Period, and (B) a number of shares of Common Stock equal to the
sum of the Daily Remaining Share Amounts for each of the 50 consecutive Trading Days in the Maturity Conversion Reference Period, in each case appropriately adjusted to reflect events occurring during the Maturity Conversion Reference Period that
would result in an adjustment to the Conversion Rate in accordance with the provisions of Section 4.06. The Company will deliver such shares of Common Stock, together with any cash payable for fractional shares, to such Holder in accordance
with Section 4.02(a). 
 (b) For the purposes of Sections 4.13(a), in the event that any of Daily Principal Share Amounts, Daily
Remaining Share Amounts or Volume Weighted Average Price is not calculable for all portions of the Maturity Conversion Reference Period, the Company’s Board of Directors shall in good faith determine the values necessary to calculate the Daily
Principal Share Amounts, Daily Remaining Share Amounts and Volume Weighted Average Price (which calculations shall be evidenced by an Officer’s Certificate delivered to the Trustee).

 COVENANTS

 Section 6.01 Payment of Securities. 
 (a) The Company shall promptly make all payments in respect of the Securities on the dates and in the manner provided in the Securities and this Indenture. A payment of principal or interest or Liquidated Damages, if
any, shall be considered paid on the date it is due if the Paying Agent (other than the Company) holds by 12:00 p.m. (noon), New York City time, on that date money, deposited by or on behalf of the Company sufficient to make the payment.
Subject to Section 4.02, accrued and unpaid interest on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security is registered at the close
of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose. Principal, Fundamental Change Repurchase Price, and interest and Liquidated 

  

 38 

 
Damages, if any, in each case if payable, shall be considered paid on the applicable date due if on such date (or, in the case of Fundamental Change
Repurchase Price, on the Business Day following the applicable Fundamental Change Repurchase Date) the Trustee or the Paying Agent holds, in accordance with this Indenture, money sufficient to pay all such amounts then due. The Company shall, to the
fullest extent permitted by law, pay interest in immediately available funds on overdue principal amount and interest at the annual rate borne by the Securities compounded semiannually, which interest shall accrue from the date such overdue amount
was originally due to the day preceding the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. 
 (b) Payment of the principal of and interest, if any, on the Securities shall be made at the office or agency of the Company maintained for that purpose
(which shall initially be the Corporate Trust Office of the Trustee) 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; provided, however, that at the option of
the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address appears in the Register; provided further that a Holder with an aggregate principal amount in excess of $5,000,000 will be paid
by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Trustee at least 10 Business Days prior to the payment date. Any wire transfer instructions received by the
Trustee will remain in effect until revoked by the Holder. Notwithstanding the foregoing, so long as this Security is registered in the name of a Depositary or its nominee, all payments thereon shall be made by wire transfer of immediately available
funds to the account of the Depositary or its nominee. 
 Section 6.02 SEC and Other Reports. 
 (a) The Company shall file in a timely fashion all reports and other information and documents which it is required to file with the SEC pursuant to
Section 13 or 15(d) of the Exchange Act (including its Annual Report on Form 10-K and its Quarterly Reports on Form 10-Q), and within 15 days after it files them with the SEC, the Company shall deliver copies of all such reports,
information and other documents to the Trustee. In the event that the Company is no longer subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall continue to provide the Trustee with reports
containing substantially the same information as would be required to be filed with the SEC had the Company continued to have been subject to such reporting requirements. In such event, such reports will be provided at the times the Company would
have been required to provide reports had it continued to be subject to such reporting requirements. The Company also shall comply with the provisions of TIA Section 314(a). 
 (b) Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such 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 hereunder (as to which the Trustee is entitled to rely
exclusively on Officer’s Certificates). 
 Section 6.03 Compliance Certificates. The Company shall deliver to the Trustee,
within 90 days after the end of each fiscal year of the Company (beginning with the fiscal year 

  

 39 

 
ending December 31, 2008), an Officer’s Certificate as to the signer’s knowledge of the Company’s compliance with all conditions and
covenants on its part contained in this Indenture and stating whether or not the signer knows of any Default or Event of Default. If such signer knows of such a Default or Event of Default, the Officer’s Certificate shall describe the Default
or Event of Default and the efforts to remedy the same. For the purposes of this Section 6.03, compliance shall be determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture.

 Section 6.04 Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further
instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 
 Section 6.05 Maintenance of Corporate Existence. Subject to Article 7, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 
 Section 6.06 Rule 144A Information Requirement. The Company covenants and agrees that it shall, during any period in which it is not
subject to Section 13 or 15(d) under the Exchange Act, upon the request of any Holder or beneficial holder of the Securities make available to such Holder or beneficial holder of Securities or any Common Stock issued upon conversion thereof
which continue to be Restricted Securities in connection with any sale thereof and any prospective purchaser of Securities or such Common Stock designated by such Holder or beneficial holder, the information required pursuant to Rule 144A(d)(4)
under the Securities Act and it will take such further action as any Holder or beneficial holder of such Securities or such Common Stock may reasonably request, all to the extent required from time to time to enable such Holder or beneficial holder
to sell its Securities or Common Stock without registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such Rule may be amended from time to time. Whether a person is a beneficial holder shall be
determined by the Company. 
 Section 6.07 Stay, Extension and Usury Laws. The Company covenants (to the extent that it may
lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any
portion of the principal of or accrued but unpaid interest or Liquidated Damages, if any, on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this
Indenture, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
 Section 6.08 Payment of Liquidated Damages. If Liquidated Damages are payable by the Company pursuant to the Registration Rights Agreement, the Company shall deliver to the Trustee an Officer’s Certificate to that effect
stating (i) the amount of such Liquidated Damages that are payable, (ii) the reason why such Liquidated Damages are payable and (iii) the date on which such Liquidated Damages are payable. Unless and until a Responsible Officer of

  

 40 

 
the Trustee receives such a certificate, the Trustee may assume without inquiry that no such Liquidated Damages are payable. If the Company has paid
Liquidated Damages directly to the Persons entitled to such Liquidated Damages, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. The Trustee may conclusively rely on the correctness of the
Liquidated Damages calculations provided by the Company without investigation. 
 Section 6.09 Maintenance of Office or Agency.
The Company will maintain an office or agency of the Trustee, Registrar and Paying Agent where securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer or purchase and where notices and
demands to or upon the Company in respect of the Securities and this Indenture may be served. The Corporate Trust Office shall initially be one such office or agency for all of the aforesaid purposes. The Company shall give prompt written notice to
the Trustee of the location, and of any change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). If at any time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 12.02. 
 The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency. 
 Section 6.10 Pledge and Escrow Agreement Deposit. Upon consummation of the initial sale of the Securities, the Company shall or shall cause
to be deposited approximately $8.0 million (plus an additional approximately $0.8 million if the option set forth in Section 2(b) of the Purchase Agreement is exercised in full) of the net proceeds from the initial sale of the Securities, in
the form of either government securities and/or cash, in the Escrow Account with the Escrow Agent. 
 ARTICLE 7 
 CONSOLIDATION; MERGER; CONVEYANCE; TRANSFER OR LEASE 
 Section 7.01 Company May Consolidate, etc., only on Certain Terms. The Company may not consolidate with or merge into any Person (unless the Company is the surviving corporation) or convey, transfer or
lease the property and assets, substantially as an entirety, of the Company to another Person, other than to one or more of the Company’s wholly-owned subsidiaries, unless: 
 (1) either (A) the Company shall be the surviving Person or (B) the Person (if other than the Company) formed by such consolidation or into
which the Company is merged, or the Person which acquires by conveyance, transfer or lease all or substantially all of the properties and assets of the Company, shall be a corporation, limited liability company, partnership, trust or other business
entity organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and shall, in any such case, expressly assume, by an indenture supplemental hereto, executed and delivered to the

  

 41 

 
Trustee, in form satisfactory to the Trustee, the obligations of the Company under the Securities and this Indenture and the performance or observance of
every covenant and provision of this Indenture and the Securities required on the part of the Company to be performed or observed; 
 (2)
after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and 
 (3) if the Company will not be the resulting or surviving corporation, the Company shall have, at or prior to the effective date of such consolidation,
merger or transfer, delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer complies with this Section 7.01 and, if a supplemental indenture is required in
connection with such transaction, such supplemental indenture complies with this Article, and that all conditions precedent herein provided for relating to such transaction have been complied with. 
 Section 7.02 Successor Substituted. Upon any consolidation of the Company with, or merger of the Company into, any other Person or any
conveyance, transfer or lease substantially as an entirety, of the properties and assets of the Company and its Subsidiaries, taken as a whole, in accordance with Section 7.01, the successor Person formed by such consolidation or into which the
Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been
named as the Company herein, and thereafter, except in the case of a lease, and except for obligations the predecessor Person may have under a supplemental indenture, the predecessor Person shall be relieved of all obligations and covenants under
this Indenture and the Securities.

 DEFAULT AND REMEDIES 
 Section 8.01 Events of Default. 
 (a) An “Event of Default” shall occur if: 
 (1) the Company shall fail to pay when due the Principal or any Fundamental Change Repurchase Price of any Security, when the same becomes due and payable; or 
 (2) the Company shall fail to pay an installment of interest or Liquidated Damages, if any, on any of the Securities, which failure continues for 30 days after the date when due; provided, however, that the
Company’s failure to pay interest (including Liquidated Damages, if any) on any of the Securities within five Business Days of any Interest Payment Date prior to and including April 1, 2010 shall constitute an immediate Event of Default;
or 
 (3) the Company shall fail to deliver when due all shares of Common Stock, if any, deliverable upon conversion of the Securities,
including any Make-Whole Premium, which failure continues for 15 days; or 
  

 42 

 (4) the Company shall fail to perform or observe (or obtain a waiver with respect to) any other term,
covenant or agreement contained in the Securities or this Indenture for a period of 60 days after receipt by the Company of a Notice of Default specifying such failure; or 
 (5) the Company shall fail to pay any principal by the end of any applicable grace period or resulting in acceleration of other Indebtedness of the
Company where the aggregate principal amount with respect to which the default or acceleration has occurred exceeds $5 million, provided that if any such default is cured, waived, rescinded or annulled, then the Event of Default by reason thereof
would be deemed not to have occurred; or 
 (6) the Company pursuant to or within the meaning of any Bankruptcy Law: 
 (A) commences as a debtor a voluntary case or proceeding; or 
 (B) consents to the entry of an order for relief against it in an involuntary case or proceeding or the commencement of any case against it; 
 (C) consents to the appointment of a Receiver of it or for all or substantially all of its property; or 
 (D) makes a general assignment for the benefit of its creditors; 
 (E) files a petition in bankruptcy or answer or consent seeking reorganization or relief; or 
 (F) consents
to the filing of such a petition or the appointment of or taking possession by a Receiver; or 
 (7) a court of competent jurisdiction
enters an order or decree under any Bankruptcy Law that: 
 (A) grants relief against the Company in an involuntary case or proceeding or
adjudicates the Company insolvent or bankrupt; 
 (B) appoints a Receiver of the Company or for all or substantially all of the property of
the Company; or 
 (C) orders the winding up or liquidation of the Company; 
 and in each case the order or decree remains unstayed and in effect for 60 consecutive days. The term “Bankruptcy Law” means Title 11 of the
United States Code (or any successor thereto) or any similar federal or state law for the relief of debtors. The term “Receiver” means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law;
or 
  

 43 

 (8) the Pledge and Escrow Agreement ceases to be in full force and effect, or enforceable, prior to its
expiration in accordance with its terms. 
 (b) Notwithstanding Section 8.01(a), no Event of Default under clauses (4) or
(5) of Section 8.01(a) shall occur until the Trustee notifies the Company in writing upon the written direction of the Holders of at least 25% in aggregate principal amount of the Securities then outstanding, or the Holders of at least 25%
in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee in writing, of the Default (a “Notice of Default”), and the Company does not cure the Default within the time specified in clause (4)
or (5) of Section 8.01(a), as applicable, after receipt of such notice. A notice given pursuant to this Section 8.01 shall be given by registered or certified mail, must specify the Default, demand that it be remedied and state that
the notice is a Notice of Default. When any Default under this Section 8.01 is cured, it ceases. 
 (c) The Company will deliver to the
Trustee, within five Business Days after becoming aware of the occurrence of a Default or Event of Default, written notice thereof. 
 The
Trustee shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to a Responsible Officer with responsibility for this Indenture at the Corporate Trust Office of the Trustee by the Company, a
Paying Agent, any Holder or any agent of any Holder or unless a Responsible Officer with responsibility for this Indenture acquires actual knowledge of such Event of Default in the course of performing other duties pursuant to this Indenture.

 Section 8.02 Acceleration. If an Event of Default (other than an Event of Default specified in clause (6) or (7) of
Section 8.01(a)) occurs and is continuing with respect to the Company, the Trustee may, by notice to the Company, and shall upon the written direction of the Holders of at least 25% in aggregate principal amount of the Securities then
outstanding, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare the principal amount and accrued and unpaid interest, if any, and accrued and unpaid
Liquidated Damages, if any, through the date of declaration on all the Securities to be immediately due and payable. Upon such a declaration, such principal amount and such accrued and unpaid interest, if any, and such accrued and unpaid Liquidated
Damages, if any, shall be due and payable immediately. If an Event of Default specified in Section 8.01(a)(6) or (7) occurs in respect of the Company and is continuing, the principal amount and accrued but unpaid interest, if any, and
accrued and unpaid Liquidated Damages, if any, on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of Securities. After a declaration of acceleration
with respect to the Securities, but before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate principal amount of the Securities then
outstanding, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: 
  

 44 

 (a) the Company has paid or deposited with the Trustee a sum sufficient to pay: 
 (i) all sums paid or advanced by the Trustee under this Indenture and the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, 
 (ii) all overdue interest, if any, on all outstanding Securities, 
 (iii) the principal of any outstanding Securities which have become due otherwise than by such declaration of acceleration and interest
thereon at the rate borne by the Securities, and 
 (iv) to the extent that payment of such interest is lawful, interest upon
overdue interest at the rate borne by the Securities; 
 (b) the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction; and 
 (c) all Defaults or Events of Default, other than the non-payment of principal of and interest on the
Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 8.04. No such rescission shall affect any subsequent Default or impair any right consequent thereon. 
 Notwithstanding the acceleration provision above, to the extent elected by the Company, the sole remedy for an Event of Default relating to the failure
to comply with the reporting obligations with respect to SEC filings that are described above under Section 6.02(a), and for any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act, will for the first
180 days after the occurrence of such an Event of Default consist exclusively of the right to receive special interest on the Securities at an annual rate equal to 0.5% of the outstanding principal amount of the Securities. This special interest
will be paid semi-annually in arrears, with the first semi-annual payment due on the first Interest Payment Date following the date on which the special interest began to accrue on any Securities. The special interest will accrue on all outstanding
Securities from and including the date on which an Event of Default relating to any failure to comply with the provisions of Section 6.02 shall first occur to but not including the 180th day thereafter (or earlier, if the Event of Default
relating any failure to comply with the provisions of Section 6.02 is cured or waived prior to such 180th day). On such 180th day (or earlier, if the Event of Default relating any failure to comply with the provisions of Section 6.02 is
cured or waived prior to such 180th day), such special interest will cease to accrue and, if the Event of Default relating to any failure to comply with Section 6.02 shall not have been cured or waived prior to such 180th day, the Securities
will be subject to acceleration as provided in this Section 8.02. In the event the Company does not elect to pay special interest upon an Event of Default in accordance with this paragraph, the Securities will be subject to acceleration as
provided in this Section 8.02. 
 Section 8.03 Other Remedies. 
 (a) If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy by proceeding at law or
in equity to collect 

  

 45 

 
payment of the principal amount and accrued and unpaid interest, if any, and accrued and unpaid Liquidated Damages, if any, on the Securities or to enforce
the performance of any provision of the Securities or this Indenture. 
 (b) The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute
a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by applicable law. 
 Section 8.04 Waiver of Defaults and Events of Default. Subject to Sections 8.02, 8.07 and 11.02, the Holders of a majority in aggregate
principal amount of the Securities then outstanding by notice to the Trustee may waive an existing Default or Event of Default and its consequences, except an uncured Default or Event of Default in the payment of the principal of, premium, if any,
or any accrued but unpaid interest on any Security, an uncured failure by the Company to convert any Securities into Common Stock or any Default or Event of Default in respect of any provision of this Indenture or the Securities which, under
Section 11.02, cannot be modified or amended without the consent of the Holder of each Security affected. When a Default or Event of Default is waived, it is cured and ceases to exist. 
 Section 8.05 Control by Majority. The Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the
time method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the
Trustee determines may be unduly prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability unless the Trustee is offered security or indemnity satisfactory to it; provided, however, that the
Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 
 Section 8.06
Limitations on Suits. 
 (a) A Holder may not pursue any remedy with respect to this Indenture or the Securities (except actions for
payment of overdue principal, premium, if any, or interest or for the conversion of the Securities pursuant to Article 4) unless: 
 (1)
the Holder gives to the Trustee written notice of a continuing Event of Default; 
 (2) the Holders of at least 25% in aggregate principal
amount of the then outstanding Securities make a written request to the Trustee to pursue the remedy; 
 (3) such Holder or Holders offer to
the Trustee security or indemnity acceptable to the Trustee against any loss, liability or expense; 
 (4) the Trustee does not comply with
the request within 60 days after receipt of the request and the offer of security or indemnity; and 
  

 46 

 (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day
period by the Holders of a majority in aggregate principal amount of the Securities then outstanding. 
 (b) No Holder of a Security shall
have any right under any provision of this Indenture or the Securities to affect, disturb, or prejudice the rights of another Holder of a Security or to obtain a preference or priority over another Holder of a Security. 
 Section 8.07 Rights of Holders to Receive Payment and to Convert. Notwithstanding any other provision of this Indenture, the right of any
Holder of a Security to receive payment of the principal amount, Fundamental Change Repurchase Price, or Make-Whole Premium and interest, if any or Liquidated Damages, if any, in respect of the Securities held by such Holder, on or after the
respective due dates expressed in the Securities and this Indenture, (whether upon repurchase or otherwise), and to convert such Security in accordance with Article 4, and to bring suit for the enforcement of any such payment on or after such
respective due dates or for the right to convert in accordance with Article 4, is, subject to compliance with the provisions of Section 8.06, absolute and unconditional and shall not be impaired or affected without the consent of the
Holder. 
 Section 8.08 Collection Suit by Trustee. If an Event of Default described in clause (1) or (2) of
Section 8.01(a) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole amount owing with respect to the Securities and
such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 Section 8.09 Trustee may File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to
the Company (or any other obligor on the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any money or other property payable or deliverable on any such claims and to distribute the same, and any
Receiver in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 9.07, and to the extent that such payment of the reasonable
compensation, expenses, disbursements and advances in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other
property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or
consent to, or, on behalf of any Holder, to authorize, accept or adopt any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of
the claim of any Holder in any such proceeding.

 Section 8.10 Priorities. 
 (a) If the Trustee collects any money pursuant to this Article 8, it shall pay out the money in the following order: 
 (1) First, to the Trustee for amounts due under Section 9.07; 
 (2) Second, to Holders for amounts due and unpaid on the Securities for the principal amount, interest, and Liquidated Damages, as applicable, ratably, without preference or priority of any kind, according to such
respective amounts due and payable on the Holders’ Securities; and 
 (3) Third, the balance, if any, to the Company. 
 (b) The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 8.10. 
 Section 8.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the
Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys’ fees and expenses (whether incurred before trial, at trial, on appeal or in any bankruptcy or arbitration or other administrative proceeding), against any party litigant in the suit, having due regard to the
merits and good faith of the claims or defenses made by the party litigant. This Section 8.11 does not apply to a suit made by the Trustee, a suit by a Holder pursuant to Section 8.07, or a suit by Holders of more than 10% in aggregate
principal amount of the Securities then outstanding. This Section 8.11 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
 ARTICLE 9 
 TRUSTEE

in aggregate principal amount of the Securities then outstanding and being furnished with indemnity acceptable to it) exercise such of the rights and powers vested in it by this Indenture. If an Event of Default of which a Responsible Officer of the
Trustee shall have actual knowledge has occurred and is continuing, the Trustee shall use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. The Trustee, however, shall
examine any certificates and opinions which by any provision hereof are specifically required to be delivered to the Trustee to determine whether or not they conform on their face to the requirements of this Indenture, but need not confirm or
investigate the accuracy of mathematical calculations or other facts stated therein

its own gross negligent action, its own gross negligent failure to act, or its own willful misconduct, except that: 
 (1) this paragraph
does not limit the effect of Section 9.01(b); 
 (2) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer, unless it is proved that the Trustee was grossly negligent in ascertaining the pertinent facts; and

 49 

 Section 9.02 Rights of Trustee. 
 (a) Subject to Section 9.01:

stated in the document. 
 (2) Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion
of Counsel, which shall conform to Section 12.04(b). The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion of Counsel. 
 (3) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, attorneys or

of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by the Trustee at the Corporate Trust Office, and such notice references the 

  

 50 

 
Securities and this Indenture. In the absence of receipt of such notice or actual knowledge, the Trustee may conclusively assume that there is no Default,
Event of Default, or Fundamental Change. 
 (9) The rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including, without limitation as Paying Agent, Registrar and Conversion Agent, and to each
agent, custodian and other Person employed to act hereunder. 
 (10) In no event shall the Trustee be responsible or liable for special,
indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

 Section 9.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee
of Securities and may otherwise deal with the Company or an Affiliate of the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to Sections 9.10 and 9.11.

 Section 9.04 Trustee’s Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture
or the Securities. It shall not be accountable for the Company’s use of the proceeds from the Securities and it shall not be responsible for any statement in the Securities other than its certificate of authentication. 
 Section 9.05 Notice of Default or Events of Default. If a Default or an Event of Default occurs and is continuing and if it is known to a
Responsible Officer of the Trustee, the Trustee shall mail to each Holder of a Security notice of all uncured Defaults or Events of Default known to it within 90 days after it occurs or, if later, within 15 days after it becomes known to the
Trustee. However, the Trustee may withhold the notice if and for so long as a committee of its Responsible Officers in good faith determines that withholding notice is in the interests of Holders of Securities, except in the case of a Default or an
Event of Default in payment of the principal of, or premium, if any, or interest on any Security when due or in the payment of any purchase obligation, or the Company’s failure to convert Securities when obligated to convert them. This
Section 9.05 is in lieu of section 315(b) of the TIA and such provision is expressly excluded from this Indenture as permitted by the TIA. 
 Section 9.06 Reports by Trustee to Holders. 
 (a) If a report is required by TIA
Section 313, within 60 days after each May 15, beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Holder of Securities a brief report dated as of such May 15 that complies with TIA

 51 

 
each stock exchange, if any, on which the Securities are listed. The Company shall notify the Trustee whenever the Securities become listed on any stock
exchange or listed or admitted to trading on any quotation system and any changes in the stock exchanges or quotation systems on which the Securities are listed or admitted to trading and of any delisting thereof.

regard to the compensation of a trustee of an express trust). The Company shall reimburse the Trustee upon request for all reasonable disbursements, expenses and advances incurred or made by or on behalf of the Trustee in accordance with any of the
provisions of this Indenture. Such expenses may include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 
 (b) The Company shall indemnify and hold harmless the Trustee or any predecessor Trustee (which for purposes of this Section 9.07 shall include its officers, directors, employees and agents) for, and hold it
harmless against, any and all loss, liability, claim, damage or expense including taxes (other than franchise taxes and taxes based upon, measured by or determined by the income of the Trustee), incurred by it in connection with and to the extent
resulting from the acceptance or administration of its duties under this Indenture or any action or failure to act as authorized or within the discretion or rights or powers conferred upon the Trustee hereunder including the reasonable costs and
expenses of the Trustee and its counsel in defending (including reasonable legal fees and expenses whether incurred before trial, at trial, on appeal or in any bankruptcy or arbitration or other administrative proceeding) itself against any claim or
liability in connection with and to the extent resulting from the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company promptly of any claim asserted against the Trustee for which it may seek
indemnity. The Company need not pay for any settlement effected without its prior written consent, which shall not be unreasonably withheld.

 (d) To secure the Company’s payment obligations in this Section 9.07, the Trustee shall have a senior claim to which the
Securities are hereby made subordinate on all money or property held or collected by the Trustee. The obligations of the Company under this Section 9.07 shall survive the satisfaction and discharge of this Indenture or the resignation or
removal of the Trustee. 
 (e) When the Trustee incurs expenses or renders services after an Event of Default specified in clause (6) or
(7) of Section 8.01(a) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. The provisions of this Section shall survive the termination of this
Indenture.

liabilities that the retiring Trustee may have incurred while acting as Trustee) hereunder, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the
Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each Holder.

removed shall be subject to TIA Section 311(a) to the extent indicated therein. 
 ARTICLE 10

effect (except as to any surviving rights of conversion, registration of transfer or exchange of Securities herein expressly provided for and except as further provided below), and the Trustee, on demand of and at the expense of the Company, shall

which have become due and payable) or to the Final Maturity Date, as the case may be; 
 (2) the Company has paid or caused to be paid all
other sums payable hereunder by the Company; and 
  

 54 

 (3) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel,

 (b)
Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company with respect to the conversion privilege and the Conversion Rate of the Securities pursuant to Article 4, the obligations of the Company to the
Trustee under Section 9.07 and, if money shall have been deposited with the Trustee pursuant to clause (2) of Section 10.01(a), the provisions of Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.12, 6.01 and 12.05, Article 4, and this
Article 10, shall survive until the Securities have been paid in full.

shall be at least 30 days from the date of such mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders entitled to money must look to the Company for payment as general
creditors unless an applicable abandoned property law designates another person. 
 Section 10.04 Reinstatement. If the Trustee

 [FORM OF REVERSE SIDE OF SECURITY] 
 RASER TECHNOLOGIES, INC. 
 8.00% CONVERTIBLE SENIOR NOTES DUE 2013 
  

	 	1.	INTEREST 

 Raser Technologies, Inc., a Delaware corporation
(the “Company”, which term shall include any successor corporation under the Indenture hereinafter referred to), promises to pay interest on the principal amount of this Security at the rate of 8.00% per annum. The Company shall pay
interest semiannually in arrears on April 1 and October 1 of each year (each an “Interest Payment Date”), commencing October 1, 2008. Each payment of interest will include interest accrued for the period commencing on and
including the immediately preceding Interest Payment Date, provided that the first interest payment on October 1, 2008, will include interest from March 26, 2008 through the day before the relevant Interest Payment Date (or purchase date,
as the case may be). Cash interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Any payment required to be made on a day that is not a Business Day shall be made on the next succeeding Business Day with the same
force and effect as if made on such day without any interest in respect of the delay. Any reference herein to interest accrued or payable as of any date shall include any Liquidated Damages accrued or payable on such date as provided in the
Registration Rights Agreement. 
 No sinking fund is provided for the Securities. 
  

	 	2.	METHOD OF PAYMENT 

 The Company shall pay interest on this
Security (except defaulted interest) to the person who is the Holder of this Security at the close of business on March 15 or September 15, as the case may be, (each, a “Regular Record Date”) next preceding the related Interest
Payment Date. The Holder must surrender this Security to a Paying Agent to collect payment of principal. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and
private debts. The Company may pay principal and interest in respect of any Certificated Security by check or wire payable in such money; provided, however, that a Holder with an aggregate principal amount in excess of $5,000,000 will be paid by
wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Trustee at least 10 Business Days prior to the payment date. The Company may mail an interest check to the
Holder’s registered address. Notwithstanding the foregoing, so long as this Security is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds to the account of
the Depositary or its nominee. 
 Any wire transfer instructions received by the Trustee will remain in effect until revoked by the Holder.

  

	 	3.	PAYING AGENT, REGISTRAR AND CONVERSION AGENT 

 Initially,
The Bank of New York (the “Trustee”, which term shall include any successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar and 

  

 A-4 

 
Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without notice to the Holder. The Company or any of its Affiliates
may, subject to certain limitations set forth in the Indenture, act as Paying Agent. 
  

	 	4.	INDENTURE, LIMITATIONS 

 This Security is one of a duly
authorized issue of Securities of the Company designated as its 8.00% Convertible Senior Notes Due 2013 (the “Securities”), issued under an Indenture dated as of March 26, 2008 (together with any supplemental indentures thereto, the
“Indenture”), between the Company and the Trustee. The terms of this Security include those stated in the Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, (the
“TIA”) as in effect on the date of the Indenture. This Security is subject to all such terms, and the Holder of this security is referred to the Indenture and the TIA for a statement of them. Capitalized terms not defined herein have the
meaning ascribed to such terms in the Indenture. 
 The Securities are unsecured, senior obligations of the Company limited to $50,000,000
aggregate principal amount ($55,000,000 aggregate principal amount if the Initial Purchaser exercises its over-allotment option in full, except as provided for in the Indenture). The Indenture does not limit other debt of the Company, secured or
unsecured. 
  

	 	5.	REPURCHASE OF SECURITIES AT OPTION OF HOLDER UPON A FUNDAMENTAL CHANGE 

 If a Fundamental Change occurs prior to the Final Maturity Date, at the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase for cash, subject
to certain exceptions described in the Indenture all or any part specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000) of the Securities held by such Holder on a date specified by the
Company that is not less than 30 nor more than 45 days after the date of the Fundamental Change Company Notice, at a purchase price equal to 100% of the principal amount thereof together with accrued and unpaid interest, if any, and accrued and
unpaid Liquidated Damages, if any, to, but excluding, the Fundamental Change Repurchase Date. The Holder shall have the right to withdraw any Fundamental Change Repurchase Notice (in whole or in a portion thereof that is $1,000 or an integral
multiple of $1,000) at any time prior to the close of business on the Business Day next preceding the Fundamental Change Repurchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture.

  

	 	6.	CONVERSION 

 Subject to and upon compliance with the
provisions of the Indenture, a Holder may surrender for conversion into Common Stock all or any portion of this Security that is in an integral multiple of $1,000. Upon conversion, the Holders shall be entitled to receive the consideration specified
in the Indenture. No fractional share of Common Stock shall be issued upon conversion of a Security. Instead, the Company shall pay a cash adjustment as provided in the Indenture. The initial Conversion Rate of the Securities shall be 108.3658
shares of Common Stock per $1,000 principal amount of Securities, subject to adjustment in accordance 

  

 A-5 

 
with the provisions of Article 4 of the Indenture. If a Holder converts all or any portion of this Security in connection with the occurrence of certain
Fundamental Change transactions, the Conversion Rate shall be increased in the manner and to the extent described in Section 4.01(e) of the Indenture. 
 Securities surrendered for conversion (in whole or in part) during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date shall be
accompanied by payment by the Holders of such Securities in funds to the Conversion Agent acceptable to the Company of an amount equal to the interest payable on such corresponding Interest Payment Date; provided that no such payment need be
made: (1) in connection with a conversion following the Regular Record Date preceding the Final Maturity Date; (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the
corresponding Interest Payment Date; or (3) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Security. 
 A Security in respect of which a Holder has submitted a Fundamental Change Repurchase Notice may be converted only if such Holder validly withdraws such
Fundamental Change Repurchase Notice in accordance with the terms of the Indenture. 
  

	 	7.	DENOMINATIONS, TRANSFER, EXCHANGE 

 The Securities are in
registered form, without coupons, in denominations of $1,000 principal amount and integral multiples of $1,000 principal amount. A Holder may register the transfer of or exchange Securities in accordance with the Indenture. The Registrar may require
a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges that may be imposed in relation thereto by law or permitted by the Indenture. 
  

	 	8.	PERSONS DEEMED OWNERS 

 The Holder of a Security may be
treated as the owner of it for all purposes. 
  

	 	9.	UNCLAIMED MONEY 

 If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and any Paying Agent will pay the money back to the Company at its written request, subject to applicable unclaimed property law and the provisions of the Indenture. After that, Holders entitled
to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person. 
  

	 	10.	AMENDMENT, SUPPLEMENT AND WAIVER 

 Subject to certain
exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding, and an existing Default or Event of Default and its
consequence or compliance with any provision of the Indenture or the Securities may be waived in a particular instance with the consent of the Holders of a majority in aggregate principal

amount of the Securities then outstanding. Without the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the Indenture
or the Securities in certain circumstances as provided in the Indenture. 
  

	 	11.	SUCCESSOR ENTITY 

 When a successor corporation assumes all
the obligations of its predecessor under the Securities and the Indenture in accordance with the terms and conditions of the Indenture, the predecessor corporation (except in certain circumstances specified in the Indenture) shall be released from
those obligations. 
  

	 	12.	DEFAULTS AND REMEDIES 

 Under the Indenture, an Event of
Default shall occur if: 
 (1) the Company shall fail to pay when due the Principal or any Fundamental Change Repurchase Price of any
Security when the same becomes due and payable; or 
 (2) the Company shall fail to pay an installment of interest or Liquidated Damages, if
any, on any of the Securities, which failure continues for 30 days after the date when due; provided, however, that the Company’s failure to pay interest (including Liquidated Damages, if any) on any of the Securities within five
Business Days of any Interest Payment Date prior to and including April 1, 2010 shall constitute an immediate Event of Default; or 
 (3) the Company shall fail to deliver when due all shares of Common Stock, if any, deliverable upon conversion of the Securities, including any Make Whole Premium, which failure continues for 15 days; or 
 (4) the Company shall fail to perform or observe (or obtain a waiver with respect to) any other term, covenant or agreement contained in the Securities
or the Indenture for a period of 60 days after receipt by the Company of a Notice of Default specifying such failure; or 
 (5) the Company
shall fail to pay any principal by the end of any applicable grace period or resulting in acceleration of other Indebtedness of the Company where the aggregate principal amount with respect to which the default or acceleration has occurred exceeds
$5 million, provided that if any such default is cured, waived, rescinded or annulled, then the Event of Default by reason thereof would be deemed not to have occurred; or 
 (6) the Company pursuant to or within the meaning of any Bankruptcy Law: 
 (A) commences as a debtor a voluntary case or proceeding; 
 (B) consents to the entry of an order for
relief against it in an involuntary case or proceeding or the commencement of any case against it; 
  

 A-7 

 (C) consents to the appointment of a Receiver of it or for all or substantially all of its property;

 (D) makes a general assignment for the benefit of its creditors; 
 (E) files a petition in bankruptcy or answer or consent seeking reorganization or relief; or 
 (F) consents to the filing of such a petition or the appointment of or taking possession by a Receiver; or 
 (7) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 
 (A) grants relief against the Company in an involuntary case or proceeding or adjudicates the Company insolvent or bankrupt; 
 (B) appoints a Receiver of the Company or for all or substantially all of the property of the Company; or 
 (C) orders the winding up or liquidation of the Company; 
 and in each case the order or decree remains unstayed and in effect for 60 consecutive days. The term “Bankruptcy Law” means Title 11 of the United States Code (or any successor thereto) or any similar federal or state law for the
relief of debtors. The term “Receiver” means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law; or 
 (8) the Pledge and Escrow Agreement ceases to be in full force and effect, or enforceable, prior to its expiration in accordance with its terms. 
 Notwithstanding the above, no Event of Default under clauses (4) or (5) above shall occur until the Trustee notifies the Company in writing
upon the written direction of the Holders of at least 25% in aggregate principal amount of the Securities then outstanding, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the
Trustee in writing, of the Default (a “Notice of Default”), and the Company does not cure the Default within the time specified in clause (4) or (5), as applicable, after receipt of such notice. 
 If an Event of Default (other than an Event of Default specified in clause (6) or (7) above) occurs and is continuing with respect to the Company, the Trustee
may, by notice to the Company, and shall upon the written direction of the Holders of at least 25% in aggregate principal amount of the Securities then outstanding, or the Holders of at least 25% in aggregate principal amount of the Securities then
outstanding may, by notice to the Company and the Trustee, declare the principal amount and accrued and unpaid interest, if any, and accrued and unpaid Liquidated Damages, if any, through the date of declaration on all the Securities to be
immediately due and payable. Upon such a declaration, such principal amount and such accrued and unpaid interest, if any, and such accrued and unpaid Liquidated Damages, if any, shall be due and payable 

  

 A-8 

 
immediately. If an Event of Default specified in clauses (6) or (7) occurs in respect of the Company and is continuing, the principal amount and
accrued but unpaid interest, if any, and accrued and unpaid Liquidated Damages, if any, on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of
Securities. After a declaration of acceleration with respect to the Securities, but before a judgment or decree for payment of the money due has been obtained by the Trustee as provided in the Indenture, the Holders of a majority in aggregate
principal amount of the Securities then outstanding, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: 
 (a) the Company has paid or deposited with the Trustee a sum sufficient to pay: 
 (i) all
sums paid or advanced by the Trustee under this Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, 
 (ii) all overdue interest, if any, on all outstanding Securities, 
 (iii) the principal of any outstanding Securities which have become due otherwise than by such declaration of acceleration and interest
thereon at the rate borne by the Securities, and 
 (iv) to the extent that payment of such interest is lawful, interest upon
overdue interest at the rate borne by the Securities; 
 (b) the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction; and 
 (c) all Defaults or Events of Default, other than the non-payment of principal of and interest on the
Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 8.04 of the Indenture. No such rescission shall affect any subsequent Default or impair any right consequent thereon.

 Notwithstanding the acceleration provision above, to the extent elected by the Company, the sole remedy for an Event of Default relating to the failure to
comply with the reporting obligations in the Indenture with respect to SEC filings that are described under Section 6.02(a) of the Indenture, and for any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture
Act, will for the first 180 days after the occurrence of such an Event of Default consist exclusively of the right to receive special interest on the Securities at an annual rate equal to 0.5% of the outstanding principal amount of the Securities.
This special interest will be paid semi-annually in arrears, with the first semi-annual payment due on the first Interest Payment Date following the date on which the special interest began to accrue on any Securities. The special interest will
accrue on all outstanding Securities from and including the date on which an Event of Default relating to any failure to comply with the provisions of Section 6.02 of the Indenture shall first occur to but not including the 180th day thereafter
(or earlier, if the Event of Default relating any failure to comply with the provisions of Section 6.02 of the Indenture is cured or waived prior to such 180th day). On such 180th day (or earlier, if the Event of Default relating any failure to
comply with the provisions of Section 6.02 of the Indenture is cured or 

  

 A-9 

 
waived prior to such 180th day), such special interest will cease to accrue and, if the Event of Default relating to any failure to comply with
Section 6.02 of the Indenture shall not have been cured or waived prior to such 180th day, the Securities will be subject to acceleration as provided above. In the event the Company does not elect to pay special interest upon an Event of
Default in accordance with this paragraph, the Securities will be subject to acceleration as provided above. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory
to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if and so long as it determines that withholding notice is in their interests. The Company is required to file periodic
certificates with the Trustee as to the Company’s compliance with the Indenture and knowledge or status of any Default. 
  

	 	13.	TRUSTEE DEALINGS WITH THE COMPANY 

 The Bank of New York,
the initial Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or an Affiliate of the Company, and may otherwise deal with the Company or an Affiliate of
the Company, as if it were not the Trustee. 
  

	 	14.	NO RECOURSE AGAINST OTHERS 

 A director, officer, employee,
stockholder, incorporator or agent as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture nor for any claim based on, in respect of or by reason of such obligations or their
creation. The Holder of this Security by accepting this Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of this Security. 
  

	 	15.	AUTHENTICATION 

 This Security shall not be valid until the
Trustee or an authenticating agent manually signs the certificate of authentication on the other side of this Security. 
  

	 	16.	ABBREVIATIONS AND DEFINITIONS

 CERTIFICATE TO BE DELIVERED UPON EXCHANGE OR REGISTRATION OF 
 TRANSFER OF RESTRICTED SECURITIES 
  

	 	Re:	8.00% Convertible Senior Notes Due 2013 (the “Securities”) of Raser Technologies, Inc. 

 This certificate relates to $             principal amount of Securities owned in (check
applicable box) 
  

					
	 ̈    book-entry or	  	 ̈    definitive form by	  	(the “Transferor”).

 The Transferor has requested a Registrar or the Trustee to exchange or register the transfer of
such Securities. 
 In connection with such request and in respect of each such Security, the Transferor does hereby certify that the
Transferor is familiar with transfer restrictions relating to the Securities as provided in Section 2.12 of the Indenture dated as of March 26, 2008 between Raser Technologies, Inc. and The Bank of New York, as trustee (the
“Indenture”), and the transfer of such Security is being made pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “Securities Act”) (check applicable box) or the transfer or exchange,
as the case may be, of such Security does not require registration under the Securities Act because (check applicable box): 
  

	 ̈	Such Security is being transferred pursuant to an effective registration statement under the Securities Act. 

  

	 ̈	Such Security is being acquired for the Transferor’s own account, without transfer. 

  

	 ̈	Such Security is being transferred to the Company or a Subsidiary (as defined in the Indenture) of the Company. 

  

	 ̈	Such Security is being transferred to a person the Transferor reasonably believes is a “qualified institutional buyer” (as defined in Rule 144A or any successor
provision thereto (“Rule 144A”) under the Securities Act) that is purchasing for its own account or for the account of a “qualified institutional buyer”, in each case to whom notice has been given that the transfer is being
made in reliance on such Rule 144A, and in each case in reliance on Rule 144A. 

  

	 ̈	Such Security is being transferred pursuant to and in compliance with an exemption from the registration requirements under the Securities Act in accordance with Rule 144 (or
any successor thereto) (“Rule 144”) under the Securities Act. 

  

	 ̈	Such Security is being transferred pursuant to and in compliance with an exemption from the registration requirements of the Securities Act (other than an exemption referred to
above) and as a result of which such Security will, upon such transfer, cease to be a “restricted security” within the meaning of Rule 144 under the Securities Act. 

  

 A-14 

 The Transferor acknowledges and agrees that, if the transferee will hold any such Securities in the form
of beneficial interests in a Global Note which is a “restricted security” within the meaning of Rule 144 under the Securities Act, then such transfer can only be made pursuant to Rule 144A under the Securities Act and such
transferee must be a “qualified institutional buyer” (as defined in Rule 144A).
