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. TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS TO NOMINEES OF THE DEPOSITORY TRUST COMPANY OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO
TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN ARTICLE TWO OF THE INDENTURE REFERRED TO ON THE REVERSE HEREOF.”

 -14- 








 
prior to the authentication and delivery of such Securities or did not hold such offices at the date of authentication of such Securities. 
 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there
appears on such Security a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an officer or other authorized signatory of the Trustee, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. 
 The Trustee shall authenticate and deliver Securities for original issue in an aggregate Principal Amount of up to $70,000,000 upon a Company Order without any further action by the Company. The aggregate
Principal Amount of Securities outstanding at any time may not exceed the amount set forth in the foregoing sentence, except as provided in Section 2.07. 
 The Securities shall be issued only in registered form without coupons and only in denominations of $1,000 of Principal Amount and any integral multiple thereof.

office or agency where Securities may be presented for registration of transfer or for exchange (“Registrar”), an office or agency where Securities may be presented for purchase or payment (“Paying Agent”) and an office or agency
where Securities may be presented for conversion (“Conversion Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or more co-registrars, one or more additional paying
agents and one or more additional conversion agents. The term Paying Agent includes any additional paying agent, including any named pursuant to Section 4.05. The term Conversion Agent includes any additional conversion agent, including any
named pursuant to Section 4.05. 
 The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent, Conversion Agent or co-registrar (other than the Trustee). The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee by a Company Order of the name and
address of any such agent. If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any
Subsidiary or an Affiliate of either of them may act as Paying Agent, Registrar, Conversion Agent or co-registrar. 
 The Company initially appoints the Trustee as Registrar, Conversion Agent and Paying Agent in connection with the Securities. 
 SECTION 2.04.    Paying Agent to Hold Money in Trust. Except as otherwise provided herein, on or prior to each due date of payments in respect of any Security, the Company shall

writing that the

  

 -15- 








 
Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent for the making of payments in respect of the Securities and shall notify the
Trustee of any Default by the Company in making any such payment. At any time during the continuance of any such Default, the Paying Agent shall, upon the written request of the Trustee, forthwith pay to the Trustee all money so held in trust. If

by it to the Trustee and to account for any funds disbursed by it. Upon doing so, the Paying Agent shall have no further liability for the money.

surrender for registration of transfer of any Securities, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Securityholder or such Securityholder’s attorney duly authorized in writing, at the
office or agency of the Company designated as Registrar or co-registrar pursuant to Section 2.03, the Company shall execute and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new
Securities of any authorized denomination or denominations, of a like aggregate Principal Amount. The Company shall not charge a service charge for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to
pay all taxes, assessments or other governmental charges that may be imposed in connection with the transfer or exchange of the Securities from the Securityholder requesting such transfer or exchange. 
 At the option of the Holder, Securities may be exchanged for other Securities of any authorized denomination or
denominations, of a like aggregate Principal Amount, upon surrender of the Securities to be exchanged, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Securityholder or such Securityholder’s
attorney duly authorized in writing, at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities that the Holder making the exchange is
entitled to receive.

the contrary herein, so long as a Global Security remains outstanding and is held by or on behalf of the Depositary, transfers of a Global Security, in whole or in part, shall be made only in accordance with Section 2.12 and this
Section 2.06(b). Transfers of a Global Security shall be limited to transfers of such Global Security in whole, or in part, to nominees of the Depositary or to a successor of the Depositary or such successor’s nominee. 
 (c)    Successive registrations and registrations of transfers and exchanges as
aforesaid may be made from time to time as desired, and each such registration shall be noted on the register for the Securities. 
 (d)    Any Registrar appointed pursuant to Section 2.03 hereof 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)    No Registrar shall be required to make registrations of transfer or exchange of Securities during any periods designated in the text of the Securities or in this Indenture as periods during which such registration
of transfers and exchanges need not be made. 
 (f)    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 form of Securities attached hereto as Exhibit A-2 setting forth such restrictions (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 satisfactory evidence, which shall include an Opinion of Counsel, 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. Upon (i) provision of such satisfactory
evidence, or (ii) 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. 
 (g)    None of the Trustee, Paying Agent, Registrar or Conversion Agent shall have any
obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under any applicable law with respect to any transfer of any interest in any Security or any shares of Common
Stock issuable in respect thereof or otherwise pursuant to this Indenture (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Securities) other than to require delivery of such
certificates or other documentation or evidence as are expressly required by, and to do so if and when

  

 -17- 








 
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. 
 (h)    Neither the Trustee, the Registrar, the Paying Agent or the Conversion Agent
shall have any responsibility for any actions taken or not taken by the Depositary. 
 SECTION
2.07.    Replacement Securities. If any mutilated Security is surrendered to the Trustee, or the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there
is delivered to the Company and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of actual knowledge by the Company or the Trustee that such Security has been acquired by a
protected purchaser (within the meaning of Section 8-303 of the Uniform Commercial Code), the Company shall execute, and upon the Trustee’s receipt of a Company Order, 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. 
 In case 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 III hereof, the Company in its discretion may, instead of issuing a new Security, pay or purchase such Security, as the case may be. 
 Upon the issuance of any new Securities under this Section, 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 expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an additional contractual obligation of the Company,
whether or not the 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.

 The provisions of this Section are 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; Determinations of Holders’ Action. Securities outstanding at any time are all the Securities authenticated by the Trustee, except for those cancelled by it or
delivered to it for cancellation, those paid pursuant to Section 2.07 and those described in this Section 2.08 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security;
provided, however, that in determining whether the Holders of the requisite Principal Amount of Securities have given or concurred in any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned
by the Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be

  

 -18- 








 
outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Securities of
which a Responsible Officer of the Trustee has actual knowledge to be so owned shall be so disregarded. Subject to the foregoing, only Securities outstanding at the time of such determination shall be considered in any such determination (including,
without limitation, determinations pursuant to Articles VI and IX). 
 If a Security is replaced pursuant to
Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. 
 If the Paying Agent or the Conversion Agent, as the case may be, holds, in accordance with this Indenture, on a Mandatory Conversion Date, or on the Business Day following a
Fundamental Change Purchase Date, or on Stated Maturity, money sufficient to pay amounts owed with respect to Securities payable on that date with respect to the Paying Agent in respect of payments in cash in connection with a Fundamental Change or
the payment of principal at Stated Maturity, or shares of Common Stock to sufficient to fulfill all of the Company’s obligations with respect to the issuance of shares in connection with a Mandatory Conversion (including, without limitation,
shares to be issued with respect to the Principal Amount of Securities (or portions thereof) being converted in a Mandatory Conversion, accrued and unpaid Liquidated Damages, if any, thereon (accruing through but not including the Mandatory
Conversion Date), and Make Whole Premium), then immediately after such Mandatory Conversion Date, Fundamental Change Purchase Date or Stated Maturity, as the case may be, such Securities (or portion thereof) repaid or converted shall cease to be
outstanding and interest, if any (other than such interest due and payable as of the applicable conversion date), and Liquidated Damages, if any, on such Securities (or portion thereof) repaid or converted shall cease to accrue; provided that
if such Securities are to be converted in a Mandatory Conversion, notice of such Mandatory Conversion has been duly given pursuant to this Indenture and the Securities or provision therefor satisfactory to the Trustee has been made. 
 If a Security is converted in accordance with Article X, then from and after the time of conversion on the Conversion Date,
such Security shall cease to be outstanding and interest, if any, shall cease to accrue on such Security. 
 SECTION 2.09.    Temporary Securities. Pending the preparation of definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities that are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities. 
 If temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the
temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 2.03, without charge to the Holder. Upon
surrender for cancellation of any

  

 -19- 








 
one or more temporary Securities, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like Principal Amount of definitive Securities of authorized
denominations. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities. 
 SECTION 2.10.    Cancellation. All Securities surrendered for payment or purchase by the Company pursuant to Article III, conversion, redemption or
registration of transfer or exchange (other than Securities exchanged pursuant to Section 10.02), shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at
any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder that the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee.
The Company may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article X or that has been converted in a Mandatory Conversion, except as otherwise
permitted by this Indenture. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall
be disposed of by the Trustee in accordance with the Trustee’s customary procedure. 
 SECTION
2.11.    Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of the Principal Amount of the Security or the payment of any Fundamental Change Purchase Price in respect thereof, and accrued and unpaid interest and Liquidated Damages,
if any, thereon, for the purpose of conversion (including, without limitation, Mandatory Conversion), the issuance of shares of Common Stock in respect of any Make Whole Premium, and for all other purposes whatsoever, whether or not such Security be
overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 SECTION 2.12.    Global Securities. (a) 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 Section 2.06 and this Section 2.12. 
 (b)    Subject to the succeeding paragraph, every Security shall be subject to the restrictions on transfer provided in the Legend including the delivery of an Opinion of Counsel, if
so provided. Whenever any Restricted Security is presented or surrendered for registration of transfer or for 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 B, dated the date of such surrender and signed

  

 -20- 








 
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. 
 (c)    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, upon the expiration of the holding period applicable to sales thereof under Rule 144(d)(1) under the Securities Act (or any successor provision). 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 an Opinion of Counsel having substantial experience in practice under the Securities Act
and otherwise reasonably acceptable to the Company, addressed to the Company and in form acceptable to the Company, to the effect that the transfer of such Security has been made in compliance with Rule 144 or such successor provision), be exchanged
for a new Security, of like tenor and aggregate Principal Amount, which shall not bear the Legend. The Company shall inform the Trustee of the effective date of any registration statement registering 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. 
 (d)    As used in the preceding two paragraphs of this Section 2.12, the term
“transfer” encompasses any sale, pledge, transfer, hypothecation or other disposition of any Security. 
 (e)    The provisions of clauses (i), (ii), (iii) and (iv) below shall apply only to Global Securities: 
 (i)    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 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 (x) 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, (y) the Company has provided the Depositary with written notice that it has decided to discontinue
use of the system of book-entry transfer through the Depositary or any successor Depositary or (z) an Event of Default has occurred and is continuing with respect to the Securities. Any Global Security exchanged pursuant to clause (x) or
(y) above shall be so exchanged in whole and not in part, and any Global Security exchanged

  

 -21- 








 
pursuant to clause (z) 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 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. 
 (ii)    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. 
 (iii)    Subject to the provisions of clause (v) below, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members (as defined below) 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. 
 (iv)    In the event of the occurrence of any of the events specified in clause (i) above, the Company will promptly make available to the Trustee a
reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons. 
 (v)    Neither any members of, or participants in, the Depositary (collectively, the “Agent Members”) nor any other Persons on whose behalf Agent Members 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. None of the Trustee, the Paying Agent, the Registrar or the Conversion Agent shall have any
responsibility or obligation to any beneficial owner in a Global Security, an Agent Member or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any Agent Member, with respect to any ownership interest in
the Securities or with respect to the delivery to any

  

 -22- 








 
Agent Member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of Mandatory Conversion) or the payment of any amount or the delivery or any
securities or other assets, under or with respect to such Securities. All notices and communications to be given to the Securityholders and all payments and deliveries to be made to Securityholders under the Securities and this Indenture shall be
given or made only to or upon the order of the registered holders (which shall be the Depositary or its nominee in the case of the Global Security). The rights of beneficial owners in the Global Security shall be exercised only through the
Depositary subject to the applicable procedures. The Trustee, the Paying Agent, the Security Registrar and the Conversion Agent shall be entitled to rely and shall be fully protected in relying upon information furnished by the Depositary with
respect to its members, participants and any beneficial owners. The Trustee, the Paying Agent, the Security Registrar and the Conversion Agent shall be entitled to deal with the Depositary, and any nominee thereof, that is the registered holder of
any Global Security for all purposes of this Indenture relating to such Global Security (including the payment of principal, Make Whole Premium, if any, and interest and Additional Amounts, if any, and securities and other assets, and the giving of
instructions or directions by or to the owner or holder of a beneficial ownership interest in such Global Security) as the sole holder of such Global Security and shall have no obligations to the beneficial owners thereof. None of the Trustee, the
Paying Agent or the Security Registrar shall have any responsibility or liability for any acts or omissions of the Depositary with respect to such Global Security, for the records of any such depositary, including records in respect of beneficial
ownership interests in respect of any such Global Security, for any transactions between the Depositary and any Agent Member or between or among the Depositary, any such Agent Member and/or any holder or owner of a beneficial interest in such Global
Security, or for any transfers of beneficial interests in any such Global Security. 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. 
 SECTION
2.13.    CUSIP Numbers. The Company may issue the Securities with one or more “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of Mandatory
Conversion 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 Mandatory Conversion or
other notice and that reliance may be placed only on the other identification numbers printed on the Securities, and any such Mandatory Conversion 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.

 ARTICLE III 
 REDEMPTION, MANDATORY CONVERSION AND PURCHASES 
 SECTION 3.01.    Right To Redeem; Right to Mandatory Conversion. The Company shall not have the right to redeem any of the Securities prior to the Stated Maturity;
provided, however, pursuant to terms and conditions set forth in paragraphs 5 and 7 of the Securities, the Company shall have the right to cause the conversion of the Securities pursuant to a Mandatory Conversion. 
 SECTION 3.02.    Selection of Securities to be Converted in a Mandatory Conversion. If less than
all the Securities are to be converted in a Mandatory Conversion, unless the procedures of the Depositary provide otherwise, the Trustee shall select the Securities to be redeemed on a pro rata basis, or, to the extent that selection on a
pro rata basis is not practicable, by lot or by such other method the Trustee considers fair and appropriate, or otherwise, in accordance with the rules and procedures of the Depositary to the extent Global Securities are (or shall be)
registered in the name of the Depositary. The Trustee may select for Mandatory Conversion portions of the Principal Amount of Securities that have denominations of $1,000 and integral multiples thereof. 
 Securities and portions of them the Trustee selects shall be in Principal Amounts of $1,000 or an integral multiple of
$1,000. Provisions of this Indenture that apply to Securities subject to Mandatory Conversion also apply to portions of Securities, in integral multiples of $1,000, subject to Mandatory Conversion. The Trustee shall notify the Company promptly of
the Securities, or portions of Securities, in integral multiples of $1,000 to be subject to Mandatory Conversion. 
 If any Security selected for partial Mandatory Conversion is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so
far as possible) to be the portion selected for Mandatory Conversion. Securities that have been converted during a selection of Securities to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection. 
 SECTION 3.03.    Notice of Mandatory Conversion. The Company shall issue a press release and file
with the SEC a Current Report on Form 8-K announcing a Mandatory Conversion on the same Business Day that the Company elects to make a Mandatory Conversion and shall provide the Trustee with contemporaneous notice of such election, and the
Company shall as promptly as practicable thereafter shall mail a notice of Mandatory Conversion by first-class mail, postage prepaid, to each Holder of Securities to be converted in such Mandatory Conversion. 
 The press release, the Current Report on Form 8-K and the notice shall identify the Securities to be redeemed and shall
state: 
 (a)    the Trading Days for which the Company calculated it had
the right to elect to make a Mandatory Conversion; 
 (b)    the Conversion
Price in effect on the date of such notice; 
  

 -24- 








 (c)    the Mandatory Conversion Date;

 (d)    the Principal Amount of the Securities subject to such Mandatory
Conversion and the amount of accrued and unpaid Liquidated Damages, if any, thereon, to be converted in the Mandatory Conversion (both in the aggregate and per $1,000 in Principal Amount of Securities); 
 (e)    the number of shares to be issued in respect of the amounts set forth in clause
(d) above shall be calculated by dividing such amount by the Conversion Price in effect on the second Business Day immediately preceding the Mandatory Conversion Date; 
 (f)    the amount of the Make Whole Premium in connection with such Mandatory
Conversion; 
 (g)    the method for determining the number of shares of
Common Stock to be issued in respect of the Make Whole Premium, the method of calculation for the Make Whole Premium Conversion Price and the Trading Days for which the Make Whole Premium Conversion Price will be calculated; 
 (h)    the name and address of the Conversion Agent; 
 (i)    that Securities subject to Mandatory Conversion may be converted at any time
before the close of business on the second Business Day immediately preceding the Mandatory Conversion Date; 
 (j)    that Holders who want to voluntarily convert Securities subject to Mandatory Conversion in lieu of having their Securities converted pursuant to the Mandatory Conversion must
satisfy the requirements set forth in paragraph 8 of the Securities on or prior to the date set forth in clause (i) above; 
 (k)    that Securities subject to Mandatory Conversion must be surrendered to the Conversion Agent to collect the shares of Common Stock issuable in connection with the Mandatory
Conversion, and the number of shares of Common Stock to be issued in such Mandatory Conversion will equal the sum of the shares determined under clauses (e) and (g) above, rounded up, in the aggregate to the nearest whole number;

 (l)    if fewer than all the outstanding Securities are to be converted,
the certificate numbers, if any, and Principal Amounts of the particular Securities to be redeemed; 
 (m)    that, unless the Company defaults in delivering a sufficient number of shares of Common Stock to the Conversion Agent in order to issue Common Stock in respect of such Mandatory Conversion as provided herein,
interest, if any (other than on past due accrued and unpaid interest), and Liquidated Damages, if any, on Securities (or portions thereof, as the case may be) subject to Mandatory Conversion, will cease to accrue on such Securities (or portions
thereof, as the case may be) on and after the

  

 -25- 








 
Mandatory Conversion Date and such Securities (or portions thereof, as the case may be) will cease to be convertible; and 
 (n)    the CUSIP number (or certificate number, if any), if any, of the Securities
subject to Mandatory Conversion. 
 At the Company’s written request, the Trustee shall give the notice of
Mandatory Conversion in the Company’s name and at the Company’s expense; provided that the Company makes such at the time it announces such conversion in accordance with this Section 3.03 and paragraph 7 of the Securities
and the Company provides the Trustee with such notice of Mandatory Conversion for sending to the Holders. 
 SECTION 3.04.    Effect of Notice of Mandatory Conversion. Once notice of Mandatory Conversion is given, the Principal Amount of Securities (or there portion thereof, as the
case may be) subject to Mandatory Conversion shall, along with all accrued and unpaid Liquidated Damages, if any, thereon, accruing through but not including the Mandatory Conversion Date, become automatically convertible into shares of Common Stock
on the Mandatory Conversion Date at the Conversion Price in effect on the second (2nd) Business Day immediately preceding such Mandatory Conversion Date (subject to adjustments as set forth in Article X), plus such number of shares of Common Stock to be delivered in respect of the
Make Whole Premium thereon, except for Securities (or portions thereof, as the case may be) which are converted at the option of the Holder in accordance with the terms of this Indenture and the Securities. Upon surrender to the Conversion Agent,
Securities (or portions thereof, as the case may be) subject to Mandatory Conversion shall be cancelled and shares of Common Stock issued to the Holders of such Securities (or portions thereof, as the case may be) as set forth in the first sentence
of this Section 3.04, as such shall be specified in the notice to be provided by the Company pursuant to paragraph 5 of the Securities, plus, such shares of Common Stock, if any, to be issued in respect of Restricted Interest. 

SECTION 3.05.    Deposit of Shares in a Mandatory Conversion. Prior to 10:00 a.m. (New York
City time) on the Mandatory Conversion Date, the Company shall deposit with the Conversion Agent (or if the Company or a Subsidiary or an Affiliate of either of them is the Conversion Agent, shall segregate and hold in trust) an amount of shares of
Common Stock sufficient with respect to the shares of Common Stock issuable upon the conversion of the Principal Amount of all Securities (or portions thereof), and accrued and unpaid Liquidated Damages, if any, to be converted in the applicable
Mandatory Conversion on the Mandatory Conversion Date, along with shares of Common Stock to be issued with respect to the related Make Whole Premium (and with respect to Restricted Interest, if any, to the extent not issued to the Holder of a
Security (or portion thereof) subject to such Mandatory Conversion with respect to an interest payment date prior to such Mandatory Conversion Date) thereon, other than Securities (or portions of Securities subject to Mandatory Conversion) that on
or prior to such Mandatory Conversion Date have been delivered by the Company to the Trustee for cancellation or have been converted in accordance with the terms and conditions of this Indenture and the Securities. The Conversion Agent shall as
promptly as practicable return to the Company any shares of Common Stock required for the foregoing purpose because of conversion at the option of the Holders of Securities pursuant to Article X. If such shares of Common Stock are then held

  

 -26- 








 
by the Company in trust and are not required for such purpose, then such shares shall be discharged from such trust. 
 SECTION 3.06.    Securities Converted in Part in a Mandatory Conversion. Upon surrender of a Security that is converted in part pursuant to a Mandatory
Conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder, without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate Principal Amount equal
to, and in exchange for, the unconverted portion of the Principal Amount of the Security surrendered. 
 SECTION
3.07.    Purchase of Securities at Option of the Holder upon Fundamental Change. (a) If at any time that Securities remain outstanding there shall have occurred a Fundamental Change (as hereinafter defined),
Securities shall be repurchased by the Company, at the option of the Holder thereof, at a purchase price (the “Fundamental Change Purchase Price”) equal to the principal amount thereof plus accrued and unpaid interest, if any, and
Liquidated Damages, if any, thereon, up to and including the date (the “Fundamental Change Purchase Date”) fixed by the Company that is not less than 30 days nor more than 60 days after the date notice is given by Company (as set forth in
3.07(b)), subject to satisfaction by or on behalf of the Holder of the requirements set forth in Section 3.07(c). 
 Whenever in this Indenture there is a reference to the principal of any Security as of any time, such reference shall be deemed to include reference to the Fundamental Change Purchase Price payable in respect of such Security to the extent
that such Fundamental Change Purchase Price is, was or would be payable at such time, and express mention of the Fundamental Change Purchase Price in any provision of this Indenture shall not be construed as excluding the Fundamental Change Purchase
Price in those provisions of this Indenture when such express mention is not made. 
 A “Fundamental
Change” shall be deemed to have occurred at such time after the original issuance of the Securities as any of the following occur: 
 (i)    any sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all or substantially all of the assets of the Company and its
Subsidiaries, taken as a whole, to any Person or group of related persons, as defined in Section 13(d) of the Exchange Act (a “Group”) (whether or not otherwise in compliance with the provisions of this Indenture); 
 (ii)    any Person or Group other than the Company, the Guarantors or the Company’s
or its Subsidiaries’ employee benefit plans, files a Schedule TO or any schedule, form or report under the Exchange Act disclosing that such Person or Group has become the direct or indirect “beneficial owner,” as defined in Rule
13d-3 under the Exchange Act, of the Company’s common equity representing more than 50% of the voting power of the Company’s outstanding Voting Stock; 
  


 -27- 








 (iii)    consummation of any share
exchange, consolidation or merger of the Company (excluding a merger solely for the purpose of changing the Company’s jurisdiction of incorporation) pursuant to which the Common Stock will be converted into cash, securities or other property or
any sale, lease or other transfer in one transaction or a series of transactions of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to any Person other than one of the Subsidiaries;
provided, however, that a transaction where the holders of more than 50% of each class of the Company’s outstanding common equity immediately prior to such transaction own, directly or indirectly, more than 50% of such class of
common equity of the continuing or surviving corporation or transferee or the parent thereof immediately after such event shall not be a Fundamental Change (unless such transaction constitutes a Fundamental Change pursuant to another clause of this
definition); 
 (iv)    the approval by the holders of Capital Stock of the
Company of any plan or proposal for the liquidation or dissolution of the Company (whether or not otherwise in compliance with the provisions of this Indenture); or 
 (v)    the first day of which a majority of the members of the Company’s Board of
Directors are not Continuing Directors (as hereinafter defined). 
 A “beneficial
owner” shall be determined in accordance with Rule 13d-3 and Rule 13d-5 promulgated by the SEC under the Exchange Act or any successor provision, except that a Person shall be deemed to have “beneficial ownership” of all securities
that such Person has the right to acquire, whether exercisable immediately or only after the passage of time. 
 “Continuing Directors” means, as of any date of determination, any member of the Board of Directors of the Company who (i) was a member of such Board of Directors on the date of the
original issuance of the Securities or (ii) was nominated for election or elected to the Board of Directors with the approval of a majority of the Continuing Directors who were members of such Board of Directors at the time of such nomination
or election. 
 (b)    On or before the 15th day after the occurrence of a Fundamental Change, the Company shall
mail a written notice of the Fundamental Change (the “Company Fundamental Change Notice”) by first-class mail to the Trustee and to each Holder (and to beneficial owners as required by applicable law), and on or before the second
(2nd) Business Day after the occurrence of a
Fundamental Change, disclose such notice in a Current Report on Form 8-K filed with the SEC and simultaneously with such filing publish a notice containing the information to be contained in the Company Fundamental Change Notice once in a
newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at such time. The Company Fundamental

  

 -28- 








 
Change Notice shall include a form of Fundamental Change Purchase Notice to be completed by the Securityholder and shall state: 
 (i)    briefly, the events causing a Fundamental Change and the date of such Fundamental
Change; 
 (ii)    the date by which the Fundamental Change Purchase Notice
pursuant to this Section 3.07 must be given; 
 (iii)    the
Fundamental Change Purchase Date; 
 (iv)    the Fundamental Change Purchase
Price; 
 (v)    the name and address of the Paying Agent and the Conversion
Agent; 
 (vi)    the Conversion Rate, the Conversion Price and any
adjustments thereto; 
 (vii)    that Securities as to which a Fundamental
Change Purchase Notice has been given may be converted pursuant to Article X hereof only if the Fundamental Change Purchase Notice has been withdrawn in accordance with the terms of this Section 3.08; 
 (viii)    that Securities must be surrendered to the Paying Agent to collect payment;

 (ix)    that the Fundamental Change Purchase Price for any Security as to
which a Fundamental Change Purchase Notice has been duly given and not withdrawn will be paid promptly following the later of the Fundamental Change Purchase Date and the time of surrender of such Security as described in clause (viii); 

(x)    briefly, the procedures the Holder must follow to exercise rights under this
Section 3.07; 
 (xi)    briefly, the conversion rights of the
Securities; 
 (xii)    the procedures for withdrawing a Fundamental Change
Purchase Notice (as specified in Section 3.08); 
 (xiii)    that,
unless the Company defaults in making payment of such Fundamental Change Purchase Price, interest, if any, and Liquidated Damages, if any, on Securities surrendered for purchase by the Company will cease to accrue on and after the Fundamental Change
Purchase Date; 
 (xiv)    the name and address of the Paying Agent and the
Conversion Agent; and 
  

 -29- 








 (xv)    the CUSIP number of the
Securities. 
 (c)    A Holder may exercise its rights
specified in Section 3.07(a) upon delivery of a written notice of purchase (a “Fundamental Change Purchase Notice”) in the form attached to this Indenture as Annex A, together with the Securities subject thereto, to the
Company and the Paying Agent at any time prior to the close of business on the third (3rd) Business Day prior to the Fundamental Change Purchase Date, stating: 
 (i)    the certificate number of the Security that the Holder will deliver to be purchased; 
 (ii)    the portion of the Principal Amount of the Security which the Holder will deliver to be purchased, which portion must be $1,000 or an integral multiple
thereof; and 
 (iii)    that such Security shall be purchased pursuant to
the terms and conditions specified in Article III of this Indenture and paragraph 6 of the Securities. 
 The

Fundamental Change Purchase Price therefor; provided, however, that such Fundamental Change Purchase Price shall be so paid pursuant to this Section 3.07 only if the Security so delivered to the Paying Agent shall conform in all
respects to the description thereof set forth in the related Fundamental Change Purchase Notice.

 SECTION 3.09.    Deposit of Fundamental Change Purchase Price.
Prior to 10:00 a.m. (New York City time) on the Business Day prior to the Fundamental Change Purchase Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them 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 if deposited on such Business Day) sufficient to pay the aggregate Fundamental Change Purchase

authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate Principal Amount equal to, and in exchange for, the portion of the
Principal Amount of the Security so surrendered which is not purchased.

3.11.    Covenant to Comply with Securities Laws upon Purchase of Securities. When complying with the provisions of Section 3.07 hereof (provided that such offer or purchase constitutes an “issuer tender
offer” for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), the Company shall (i) comply in all material respects with Rule 13e-4
and Rule 14e-1 under the Exchange Act, (ii) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, and (iii) otherwise comply in all material respects with all Federal and state securities laws so
as to permit the rights and obligations under Section 3.07 to be exercised in the time and in the manner specified in Section 3.07.

thereof which the Company is obligated to purchase as of the Fundamental Change Purchase Date and accrued and unpaid interest thereon, if any, and Liquidated Damages, if any, then, unless otherwise agreed in writing with the Company, promptly after
the Business Day following the Fundamental Change Purchase Date, the Trustee shall return any such excess to the Company together with interest or dividends, if any, thereon (subject to the provisions of Section 7.01(f)).

shall promptly make all payments in respect of the Securities on the dates and in the manner provided in the Securities or pursuant to this Indenture. Any amounts to be given to the Trustee or Paying Agent, as the case may be, shall be deposited
with the Trustee or Paying Agent, as the case may be, in immediately available funds by 10:00 a.m. (New York City time) by the Company. Interest installments, Liquidated Damages, Principal Amount, Fundamental Change Purchase Price and interest, if
any, due on overdue amounts shall be considered paid on the applicable date due if at 10:00 a.m.

  

 -32- 








 
(New York City time) on such date (or, in the case of a Fundamental Change Purchase Price, on the Business Day following the applicable Fundamental Change Purchase Date) the Trustee or the Paying
Agent, as the case may be, holds, in accordance with this Indenture, money sufficient to pay all such amounts then due. 
 The Company shall, to the extent permitted by law, pay interest on overdue amounts at the rate per annum set forth in paragraph 1 of the Securities, compounded semiannually, which interest shall accrue
from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. The accrual of such interest on overdue amounts
shall be in addition to the continued accrual of interest on the Securities. 
 SECTION
4.02.    SEC and Other Reports. The Company shall file with the Trustee, within 15 days after it files such annual and quarterly reports, information, documents and other reports with the SEC, copies of its annual report
and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act. In the event the Company is at any time no longer subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, it shall continue to provide the Trustee with reports containing substantially the same
information as would have been required to be filed with the SEC had the Company continued to have been subject to such reporting requirements. In such event, such reports shall be provided to the Trustee at the times the Company would have been
required to provide reports had it continued to have been subject to such reporting requirements. The Trustee shall have no duty to examine any such reports, information or documents to determine whether or not they comply with the requirements of
this Section or otherwise; its only duty being to file same in its records if and when received and to make them available for inspection during normal business hours by any Holder requesting same and at the expense of the Company. 
 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 form 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 Officers’ Certificates as provided in Section 4.03). 
 SECTION
4.03.    Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ended December 31, 2009) an Officers’
Certificate, stating whether or not, to the best knowledge of the signers thereof, the Company, as of the date of such Officers’ Certificate, is in default in the performance or observance of any of the terms, provisions and conditions of this
Indenture (without regard to any period of grace or requirement of notice provided hereunder) and if the Company shall be in default, specifying all such Defaults and the nature and status thereof of which they may have knowledge. 
 The Company shall, so long as any of the Securities are outstanding, deliver to the Trustee, forthwith upon becoming aware
of any Default or Event of Default, but, in any event, within ten (10) days of becoming so aware of such Default or Event of Default, an Officers’

  

 -33- 








 
Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. 
 SECTION 4.04.    [Intentionally Omitted]. 
 SECTION 4.05.    Maintenance of Office or Agency. The Company will maintain in the Borough of
Manhattan, The City of New York, an office or agency of the Trustee, Registrar, Paying Agent and Conversion Agent where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer,
exchange, purchase, redemption or conversion 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 of the Trustee shall initially be 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 in the Borough of Manhattan, the City of New York, for such purposes. 
 SECTION 4.06.    Delivery of Certain Information. At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a Holder or
any beneficial owner of Securities or holder or beneficial owner of Common Stock delivered upon conversion thereof, the Company will promptly furnish or cause to be furnished Rule 144A Information (as defined below) to such Holder or any beneficial
owner of Securities or holder or beneficial owner of Common Stock, or to a prospective purchaser of any such security designated by any such holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule
144A under the Securities Act in connection with the resale of any such security. “Rule 144A Information” shall be such information as is specified pursuant to Rule 144A(d)(4) under the Securities Act or any successor provisions. Whether a
Person is a beneficial owner shall be determined by the Company to the Company’s reasonable satisfaction. 
 SECTION 4.07.    Limitation on Incurrence of Additional Indebtedness. So long as at least $10,000,000 in aggregate Principal Amount of Securities are outstanding, the Company will not, and will not permit any of
its Significant Subsidiaries to, directly or indirectly, create, incur, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for the payment of (collectively, “incur”) any
Indebtedness (other than Permitted Indebtedness) at any time prior to the two (2) year anniversary of the date of this Indenture. 
 SECTION 4.08.    Liquidated Damages. If at any time Liquidated Damages become payable by the Company pursuant to the Registration Rights Agreement, the Company shall promptly
deliver to the Trustee an Officers’ Certificate to that effect and stating (i) the

  

 -34- 








 
amount of such Liquidated Damages that are payable and (ii) the date on which such damages are payable pursuant to the terms of the Registration Rights Agreement. Unless and until a
Responsible Officer of the Trustee receives such Officers’ Certificate at the Corporate Trust Office of the Trustee, the Trustee may assume without inquiry that no Liquidated Damages are payable. If the Company has paid Liquidated Damages
directly to the Persons entitled to them, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. 
 SECTION 4.09.    Reverse Stock Split; Combination of Shares. The Company shall not implement or cause a reverse stock split or a combination of its shares
of Common Stock at any time prior to the 60th calendar day
after the date of this Indenture. 
 SECTION 4.10.    Existence. Subject to
Article V, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence and rights (charter and statutory); provided, however, that the Company shall not be required to
preserve any such right if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders of the
Securities. 
 ARTICLE V

transaction, such supplemental indenture, comply with this Article V and that all conditions precedent herein provided for relating to such transaction have been complied with. 
 For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise) of the properties and assets of one or more Subsidiaries (other than to the Company or

  

 -35- 








 
another Subsidiary), which, if such assets were owned by the Company would constitute all or substantially all of the properties and assets of the Company shall be deemed to be the transfer of
all or substantially all of the properties and assets of the Company. 
 SECTION
5.02.    Successor Corporation to be Substituted. The successor corporation formed by such consolidation or into which the Company is merged or the successor corporation 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 had been named as the Company herein; and thereafter, except in the case of a lease and
except for the obligations the Company may have under a supplemental indenture pursuant to Section 10.12, the Company shall be discharged from all obligations and covenants under this Indenture and the Securities. Subject to Section 9.06,
the Company, the Trustee (upon a Company Order) and the successor corporation shall enter into a supplemental indenture (with endorsements of Guarantees thereon by the Guarantors) to evidence such succession, substitution and exercise of every right
and power of such successor corporation and such discharge and release of the Company.

elapsed), aggregates $10,000,000 or more at any time; 
  

 -36- 








 (e)    the Company or a Significant

 (h)    a court having jurisdiction in the premises shall enter a decree or order for
relief in respect of the Company or any Significant Subsidiary of the Company in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee,
custodian, trustee or sequestrator (or similar official) of the Company or for any substantial part of its property or ordering the winding up or liquidation of its affairs and such decree or order shall remain unstayed and in effect for a period of

 (i)    the Company or any Significant Subsidiary of the
Company shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the
appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Company or such Subsidiary of the Company or for any substantial part of its property or make any general
assignment for the benefit of creditors. 
 The Company shall deliver to the Trustee, within 10 days after it
becomes aware of the occurrence thereof, written notice of any event which with the giving of notice or the lapse of time, or both, would become an Event of Default under clause (c) or (d) above, its status and what action the Company is
taking or proposes to take with respect thereto. 
 SECTION 6.02.    Defaults and
Remedies. If an Event of Default (other than an Event of Default specified in Section 6.01(h) or 6.01(i) with respect to the Company) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in
aggregate Principal Amount of the Securities at the time outstanding by notice to the Company and the Trustee, may declare the Principal Amount of all the Securities plus accrued and unpaid interest, if any, and Liquidated Damages, if any, thereon,
through the date of declaration to be immediately due and payable. Upon such a declaration, such Principal Amount plus accrued and unpaid interest, if any, and Liquidated Damages, if any, shall become and be immediately due and payable subject to
the provisions of Article XI. If an Event of Default specified in Section 6.01(h) or 6.01(i), solely with respect to the Company, occurs and is continuing, the Principal

  

 -37- 








 
Amount of all the Securities plus accrued and unpaid interest, if any, and Liquidated Damages, if any, thereon, shall become and be immediately due and payable without any declaration or other
act on the part of the Trustee or any Securityholder. 
 The Holders of a majority in principal amount of the
Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of and accrued and unpaid interest, if any, and Liquidated
Damages, if any, on the Securities which has become due solely by such declaration of acceleration, have been cured or waived; (b) the Company has paid or deposited with the Trustee a sum in immediately available funds sufficient to pay
(i) all overdue interest, if any, and Liquidated Damages, if any, on the Securities, (ii) the principal of any Security which has become due otherwise then by such declaration of acceleration, and (iii) to the extent the payment of
such interest is lawful, interest on overdue installments of interest and Liquidated Damages, if any, and overdue principal, which has become due otherwise than by such declaration of acceleration; (c) the rescission would not conflict with any
judgment or decree of a court of competent jurisdiction; and (d) all payments due to the Trustee and any predecessor Trustee under Section 7.07 have been made. No such rescission shall affect any subsequent Default or Event of Default or
impair any right consequent thereon. 
 SECTION 6.03.    Other Remedies. If an Event
of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of the Principal Amount of all the Securities plus all accrued and unpaid interest, if any, and Liquidated Damages, if any, thereon or to enforce
the performance of any provision of the Securities or this Indenture. 
 The Trustee may maintain a proceeding
even if the Trustee does not possess any of the Securities or does not produce any of the Securities in the proceeding. A delay or omission by the Trustee or any Securityholder 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 law. 
 SECTION 6.04.    Waiver of Past Defaults. The Holders of a majority in aggregate Principal Amount
of the Securities at the time outstanding, by notice in writing to the Trustee (and without notice to any other Securityholder), may waive an existing Default and its consequences, except (a) an Event of Default described in
Section 6.01(a) or 6.01(b), (b) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Securityholder affected or (c) a Default which constitutes a failure to convert any
Security in accordance with the terms of Article X. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. This Section 6.04 shall be in lieu of
Section 316(a)1(B) of the TIA and such Section 316(a)1(B) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
 SECTION 6.05.    Control by Majority. The Holders of a majority in aggregate Principal Amount of the Securities at the time outstanding may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee
determines in good faith is unduly

  

 -38- 








 
prejudicial to the rights of other Securityholders or, unless the Trustee is offered indemnity satisfactory to it, would involve the Trustee in personal liability. This Section 6.05 shall be
in lieu of Section 316(a)1(A) of the TIA and such Section 316(a)1(A) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
 SECTION 6.06.    Limitation on Suits. A Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless: 
 (a)    the Holder gives to the Trustee written notice stating that an Event of Default
is continuing; 
 (b)    the Holders of at least 25% in aggregate Principal
Amount of the Securities at the time outstanding make a written request to the Trustee to pursue the remedy; 
 (c)    such Holder or Holders offer to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense; 
 (d)    the Trustee does not comply with the request within 60 days after receipt of such
notice, request and offer of security or indemnity; and 
 (e)    the
Holders of a majority in aggregate Principal Amount of the Securities at the time outstanding do not give the Trustee a direction inconsistent with the request during such 60-day period. 
 A Securityholder may not use this Indenture to prejudice the rights of any other Securityholder or to obtain a preference or
priority over any other Securityholder. 
 SECTION 6.07.    Rights of Holders to Receive
Payment. Subject to the provisions of Article XI hereof, notwithstanding any other provision of this Indenture, the right of any Holder to receive payment (provided, however, that without the prior written consent of a Holder
affected thereby, payments to be made to such Holder in shares of Common Stock cannot be made in cash in lieu of delivering such shares) of interest installments, Liquidated Damages, if any, the Principal Amount (including, without limitation, the
Principal Amount of any Securities (or portions thereof) subject to conversion in a Mandatory Conversion or a conversion at the option of the Holder that have not been converted in full as of such date in accordance with the terms and conditions of
this Indenture and the Securities), Make Whole Premium, Fundamental Change Purchase Price or interest, if any, due on overdue amounts in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities,
and to convert the Securities in accordance with Article X, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be impaired or affected adversely without the consent of such
Holder. 
 SECTION 6.08.    Collection Suit by Trustee. If an Event of Default
described in Section 6.01(a), 6.01(b) or 6.01(f) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount owing with respect to the Securities and the
amounts provided for in Section 7.07. 
  

 -39- 








 SECTION 6.09.    Trustee May File Proofs of
Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company, any Guarantor or any other obligor upon the
Securities or the property of the Company, any Guarantor or of such other obligor or their creditors, the Trustee (irrespective of whether interest installments, Liquidated Damages, if any, the Principal Amount (including, without limitation, the

Liquidated Damages, if any, the whole amount of the Principal Amount (including, without limitation, the Principal Amount of any Securities (or portions thereof) subject to conversion in a Mandatory Conversion that have not been converted in full as
of such date in accordance with the terms and conditions of this Indenture and the Securities), Make Whole Premium, Fundamental Change Purchase Price or interest, if any, due on overdue amounts in respect of the Securities, and to file such 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 or any other amounts
due the Trustee under Section 7.07) and of the Holders allowed in such judicial proceeding, and 
 (b)    to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar
official 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 the Trustee any amount
due 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 7.07. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of
any Holder 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.

any Securities (or portions thereof) subject to conversion in a Mandatory Conversion or conversion at the option of a Holder that have not been converted in full as of such date in accordance with the terms and conditions of this Indenture and the
Securities), Fundamental Change Purchase Price, to the extent sufficient shares of Common Stock are not issued in respect thereof, the Make Whole Premium, or interest, if any, due on overdue amounts in respect of the Securities, as the case may be,

Securityholder and the Company a notice that states the record date, the payment date and the amount to be paid (to the extent such information is then known by the Trustee and is not superseded by an order issued by a court of competent
jurisdiction). 
 SECTION 6.11.    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 (other than the Trustee) 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, 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate Principal Amount of the

that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury or other law wherever enacted, now or at any time hereafter
in force, which would prohibit or forgive the Company from paying all or any portion of any interest installment, Liquidated Damages, if any, the Principal Amount (including, without limitation, the Principal Amount of any Securities (or portions

calculations or other facts, statements, conclusions or opinions contained therein). 
     This Section 7.01(b) shall be in lieu of Section 3.15(a) of the TIA and such Section 315(a) is hereby expressly excluded from this Indenture, as permitted by the TIA.

 (m)    the Trustee shall not be required to give any bond or surety in respect of the
performance of its duties hereunder. 
 SECTION 7.03.    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 its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent,

Securities, it shall not be accountable for the Company’s use or application of the proceeds from the Securities, it shall not be responsible for any statement in any registration statement for the Securities under the Securities Act, in any
offering document for, or in any document entered into in connection with the sale of, the Securities, in the Indenture or in the Securities (other than its certificate of authentication), all of which statements shall be taken as the statements of
the Company. The Trustee shall have no duty to see to the performance or observance of, or to perform or observe, any of the covenants and agreements on the part of the Company, any Guarantor or any other Person to be performed or observed under
this Indenture or any of the Securities or Guarantees. The Trustee shall not be responsible for making any calculation or computation in respect of any matter referred to in this Indenture.

known to a Responsible Officer of the Trustee, the Trustee shall give to each Securityholder notice of all such Defaults known to it within 90 days after any such Default occurs or, if later, within 15 days after it is actually known to a
Responsible Officer of the Trustee, unless such Default shall have been cured or waived before the giving of such notice. Notwithstanding the preceding sentence, except in the case of a Default described in Sections 6.01(a) and 6.01(b), if and as
long as the Trustee also acts in the capacity of the Paying Agent, the Trustee may withhold the notice if and so long as a committee of Responsible Officers of the Trustee in good faith determines that withholding the notice is in the interests of
Securityholders. The second sentence of this Section 7.05 shall be in lieu of the proviso to Section 315(b) of the TIA and such proviso is hereby expressly excluded from this Indenture, as permitted by the TIA. 
 SECTION 7.06.    Reports by Trustee to Holders. Within 60 days after each May 15 beginning

listed on any Securities exchange and of any delisting thereof. 
  

 -45- 








 SECTION 7.07.    Compensation and Indemnity. The
Company agrees: 
 (a)    to pay to the Trustee from time to time, and the
Trustee shall be entitled to, such compensation as the Company and the Trustee shall from time to time agree in writing for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust); 
 (b)    to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture or any documents executed in connection herewith (including the reasonable
compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its gross negligence or willful misconduct; and 
 (c)    to indemnify the Trustee or any predecessor Trustee and their agents, officers,
directors and employees for, and to hold them harmless against, any and all loss, damage, claim, liability, cost or expense (including attorneys’ fees and expenses and taxes (other than taxes based upon, measured by or determined by the income
of the Trustee)) incurred without gross negligence or willful misconduct on its part, arising out of or in connection with this Indenture, the Securities and the acceptance or administration of the trust or trusts hereunder, including the costs and
expenses of defending itself against any claim (whether asserted by the Company or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, or in connection with enforcing
the provisions of this Section. 
 To secure the Company’s obligations in this Section 7.07, the
Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay interest installments, Liquidated Damages, if any, the Principal Amount (including, without limitation, the
Principal Amount of any Securities (or portions thereof) subject to conversion in a Mandatory Conversion or a conversion at the option of a Holder that have not been converted in full as of such date in accordance with the terms and conditions of
this Indenture and the Securities), Fundamental Change Purchase Price or interest, if any, due on overdue amounts, or shares of Common Stock to be issued with respect to any Mandatory Conversion, conversion at the election of any Holder, Restricted
Interest or Make Whole Premium, as the case may be, in respect of any particular Securities (or portions thereof). 
 The Company’s obligations pursuant to this Section 7.07 and the lien provided for herein shall survive the satisfaction and discharge of this Indenture and the Securities, the termination for any reason of this Indenture and the
removal or resignation of the Trustee. In addition to, and without prejudice to its other rights hereunder, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(h) or Section 6.01(i), the
expenses, including the reasonable charges and expenses of its counsel, and the compensation for the services, are intended to constitute expenses of administration under any bankruptcy law.

 SECTION 7.08.    Replacement of Trustee. The
Trustee may resign by so notifying the Company; provided, however, that no such resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 7.08. The Holders of a majority in
aggregate Principal Amount of the Securities at the time outstanding may remove the Trustee by so notifying the Trustee and the Company. The Company shall remove the Trustee if: 
 (a)    the Trustee fails to comply with Section 7.10; 
 (b)    the Trustee is adjudged bankrupt or insolvent; 
 (c)    a receiver or public officer takes charge of the Trustee or its property; or

 (d)    the Trustee otherwise becomes incapable of acting. 
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall
promptly appoint, by resolution of its Board of Directors, a successor Trustee. 
 A successor Trustee shall
deliver a written acceptance of its appointment to the retiring Trustee and to the Company satisfactory in form and substance to the retiring Trustee and the Company. Thereupon 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. The successor Trustee shall mail a notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. 
 If a successor Trustee does not take office within 30 days after the retiring Trustee gives its notice of resignation or is removed, the retiring Trustee, the Company or the Holders of a majority in aggregate Principal Amount of the
Securities at the time outstanding may petition any court of competent jurisdiction at the expense of the Company for the appointment of a successor Trustee. 
 If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee. 
 SECTION 7.09.    Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets (including the administration of the trust created by this Indenture) to, another corporation, the resulting, surviving or
transferee corporation without any further act shall be the successor Trustee. 
 SECTION
7.10.    Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA Section 310(a)(1). The Trustee (or its parent holding company) shall have a combined capital and surplus of at
least $50,000,000 as set forth in its most recent published annual report of condition. Nothing herein contained shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA Section

  

 -47- 








 
310(b). The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or
indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. 
 SECTION 7.11.    Preferential Collection of Claims Against Company. The Trustee shall comply with
TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. 
 ARTICLE VIII 
 DISCHARGE OF INDENTURE 
 SECTION 8.01.    Discharge of Liability on
Securities. When (i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.07) for cancellation or (ii) all outstanding Securities have become due and payable and the
Company deposits with the Trustee Cash, in immediately available funds, sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.07), and if in either case the Company pays
all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 7.07, cease to be of further effect. The Trustee shall join in the execution of a document prepared by the Company acknowledging satisfaction and
discharge of this Indenture on demand at the cost and expense of the Company and accompanied by an Officers’ Certificate and Opinion of Counsel. 
 SECTION 8.02.    Repayment to the Company. The Trustee and the Paying Agent shall return to the Company upon written request any money held by them for the payment of any amount
with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, as applicable, Holders entitled to the money must look to the Company for payment as general creditors
unless an applicable abandoned property law designates another person and the Trustee and the Paying Agent shall have no further liability to the Securityholders with respect to such money or securities for that period commencing after the return
thereof. 
 ARTICLE IX

compliance by the Company with restrictive provisions of this Indenture other than as set forth in this Section 9.02 below, and waive any past Default under this Indenture and its consequences, except a Default in the payment of the principal
of or interest on any Security or in respect of a provision which under this Indenture cannot be modified or amended without the consent of the Holder of each outstanding Security affected.

Securities the obligation of the Company to make and consummate a Fundamental Change offer in the event of a Fundamental Change or, after such Fundamental Change has occurred, modify any of the provisions of this Indenture with respect thereto, or
modify any provisions relating to the issuance of shares in respect of a Mandatory Conversion or Make Whole Premium after the Company has elected to make a Mandatory Conversion or the Holders have elected to convert their Securities, in each case,
with respect to such Securities selected for Mandatory Conversion by the Company or conversion by the Holders, as the case may be;

 It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be
sufficient if such consent approves the substance thereof. 
 After an amendment under this Section 9.02
becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. Failure to mail the notice or a defect in the notice shall not effect the validity of the amendment. 
 SECTION 9.03.    Compliance with Trust Indenture Act. Every supplemental indenture executed
pursuant to this Article IX shall comply with the TIA. 
 SECTION 9.04.    Revocation and
Effect of Consents. Until an amendment, waiver or other action by Holders becomes effective, a consent thereto by a Holder of a Security hereunder is a continuing consent by the Holder and every subsequent Holder of that Security or portion of
the Security that evidences the same obligation as the consenting Holder’s Security, even if notation of the consent, waiver or action is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent, waiver or
action as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date

  

 -50- 








 
the amendment, waiver or action becomes effective. After an amendment, waiver or action becomes effective, it shall bind every Securityholder. 
 SECTION 9.05.    Notation on or Exchange of Securities. Securities authenticated and delivered
after the execution of any supplemental indenture pursuant to this Article IX may, and shall if required by the Trustee, bear a notation in form approved by the Company and the Trustee as to any matter provided for in such supplemental indenture. If
the Company shall so determine, new Securities so modified as to conform, in the opinion of the Trustee and the Board of Directors of the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and
delivered by the Trustee in exchange for outstanding Securities. 
 SECTION
9.06.    Trustee to Sign Supplemental Indentures. The Trustee shall sign any supplemental indenture authorized pursuant to this Article IX if the amendment contained therein does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign such supplemental indenture. In signing such supplemental indenture the Trustee shall receive, and (subject to the provisions of Section 7.01) shall be
fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such supplemental indenture is authorized or permitted by this Indenture. 
 SECTION 9.07.    Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article IX, this Indenture shall be
modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes, and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

 ARTICLE X 
 CONVERSIONS 
 SECTION
10.01.    Conversion Privilege. Subject to the limitations on conversion set forth in Section 10.16 of this Indenture and paragraph 8 of the Security, a Holder of a Security may convert such Security into Common
Stock (the shares of Common Stock issuable upon such conversion, the “Conversion Shares”), at the Conversion Price then in effect. 
 The number of shares of Common Stock issuable upon conversion of a Security shall be determined by the Company by dividing the principal amount of the Security or portion thereof surrendered for
conversion by the Conversion Price in effect on the Conversion Date. The initial Conversion Price is set forth in paragraph 8 of the Securities and is subject to adjustment as provided in this Article X. 
 A Holder may convert the principal amount of a Security equal to $1,000 or any integral multiple thereof. Provisions of this
Indenture that apply to conversion of all of a Security also apply to conversion of $1,000 principal amount or multiples thereof of less than all of a Security. 
 If a Security is subject to Mandatory Conversion pursuant to Article III, the right to convert such Security shall terminate at the close of business on the second Business Day
before the Mandatory Conversion Date for such Security (unless the Company shall default in

  

 -51- 








 
delivering the shares required to be delivered in connection with such Mandatory Conversion to the Conversion Agent as required pursuant to the terms of this Indenture and the Securities, in
which case the conversion right shall terminate on the date such default is cured and such Security is converted pursuant to such Mandatory Conversion). A Security in respect of which a Holder has delivered a Fundamental Change Purchase Notice
pursuant to Section 3.07 exercising the option of such Holder to require the Company to repurchase such Security may be converted only if such Fundamental Change Purchase Notice is withdrawn by a written notice of withdrawal delivered to the
Paying Agent prior to the close of business on the Business Day prior to the close of business on the Fundamental Change Purchase Date in accordance with Section 3.08. 
 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, upon such conversion, only to
the extent such Securities are deemed to have been converted into Common Stock pursuant to this Article X. 
 Upon conversion of the Securities by a Holder pursuant to this Article X or pursuant to a Mandatory Conversion at the option of the Company pursuant to paragraph 5 of the Securities, the Company shall
also pay to such Holder a make whole premium (“Make Whole Premium”) on each Security converted equal to the sum of undiscounted interest that would have been paid on the principal amount of such Security from the last date interest was
paid on such Security immediately prior to such conversion or Mandatory Conversion, as the case may be, through and including the Stated Maturity as though such Security had remained outstanding through the Stated Maturity. The Make Whole Premium
will be payable in shares of Common Stock at a price per share of Common Stock (the “Make Whole Premium Conversion Price”) equal to 95% of the simple arithmetic average of the Weighted Average Price of the shares of Common Stock (as
reported by Bloomberg) for each of the, (x) with respect to a conversion other than a Mandatory Conversion, five (5) consecutive Trading Days ending on the second (2nd) Trading Day immediately preceding the date of such conversion, and (y) with respect to a Mandatory
Conversion, 10 consecutive Trading Days ending on the second (2nd) Trading Day immediately preceding such Mandatory Conversion Date; provided that in no event shall the Make Whole Premium Conversion Price be less than $0.38 per share of Common Stock (as appropriately adjusted for any stock
dividend, stock split, stock combination or other similar transaction) or greater than the Conversion Price then in effect; provided, further, that for the purposes hereof, the number of shares of Common Stock issuable with respect to
the Make Whole Premium will be subject to the limitations set forth in Section 10.16 and in paragraph 8 of the Security. 
 SECTION 10.02.    Conversion Procedure. To convert a Security, a Holder must satisfy the requirements in paragraph 8 of the Securities and (i) complete and manually sign
the conversion notice on the back of the Security and deliver such notice to the Conversion Agent, (ii) surrender the Security to the Conversion Agent, (iii) furnish appropriate endorsements and transfer documents if required by the
Registrar or the Conversion Agent, (iv) pay any transfer or other tax, if required by Section 10.04 and (v) if the Security is held in book-entry form, complete and deliver to the Depositary appropriate instructions pursuant to the
Depositary’s book-entry conversion programs. The date on which the Holder satisfies all of the foregoing requirements is the “Conversion Date”. As soon as practicable, but in no event more than three

  

 -52- 








 
(3) Business Days, after the Conversion Date, the Company shall deliver to the Holder through the Conversion Agent a book-entry notation of the number of whole shares of Common Stock issuable
upon the conversion. 
 The Person in whose name the certificate is registered shall be deemed to be a
stockholder of record on the Conversion Date; provided, however, that no surrender of a Security on any 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 such 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
Price in effect on the date that such Security shall have been surrendered for conversion, 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.

 No payment or adjustment will be made for accrued interest, if any, or Liquidated Damages, if any, on a
converted Security (except with respect to the payment of the Make Whole Premium) or for dividends or distributions on shares of Common Stock issued upon conversion of a Security (provided that the shares of Common Stock received upon
conversion of Securities shall continue to accrue Liquidated Damages, as applicable, in accordance with the Registration Rights Agreement and shall be entitled to receive, at the next interest payment date, any accrued and unpaid Liquidated Damages
with respect to the converted Securities), but if any Holder surrenders a Security for conversion between the record date for the payment of an installment of interest and the next interest payment date, then, notwithstanding such conversion, the
interest or Liquidated Damages, if any, payable on such interest payment date shall be paid to the Holder of such Security on such record date. In such event, such Security, when surrendered for conversion, must be accompanied by delivery of a check
payable to the Conversion Agent in an amount equal to the interest or Liquidated Damages, if any, payable on such interest payment date on the portion so converted. If such payment does not accompany such Security, the Security shall not be
converted; provided, however, that no such check shall be required if such Security is subject to a Mandatory Conversion on a Mandatory Conversion Date within the period between and including such record date and such interest payment
date, or if such Security is surrendered for conversion on the interest payment date. If the Company defaults in the payment of interest or Liquidated Damages, if any, payable on the interest payment date, the Conversion Agent shall repay such funds
to the Holder. The Conversion Rate, Conversion Price and the Make Whole Premium shall be calculated by the Company and communicated to the Trustee in the form of an Officers’ Certificate. 
 If a Holder converts more than one Security at the same time, the number of shares of Common Stock issuable upon the
conversion shall be based on the aggregate principal amount of Securities converted. 
 Upon surrender of a
Security that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new Security equal in principal amount to the unconverted portion of the Security surrendered. 
  

 -53- 








 SECTION 10.03.    Adjustments Below Par Value.
Before taking any action which would cause an adjustment decreasing the Conversion Price so that the shares of Common Stock issuable upon conversion of the Securities would be issued for less than the par value of such Common Stock, the Company will
take all corporate action which may be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of such Common Stock at such adjusted Conversion Price. 
 SECTION 10.04.    Taxes on Conversion. If a Holder converts a Security, the Company shall pay any
documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon such conversion. However, 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 certificates 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 regulations. 
 SECTION 10.05.    Company to Provide Stock. 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 for shares of Common Stock and the issuance of shares in connection with the Make Whole
Premium and the payment of Restricted Interest; provided, however, that the Company shall not be required to reserve an amount of shares in excess of the limitation set forth in Section 10.16 to the extent such limitation is then
applicable. The shares of Common Stock or other securities issued upon conversion of Securities bearing a Legend as provided in Section 2.06(f) shall bear a legend substantially in the following form: 
 “THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED
STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS SECURITY
IS HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT. 
 THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) TO A PERSON WHOM THE SELLER REASONABLY
BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR AN ACCREDITED INVESTOR (AS DEFINED IN RULE 501 UNDER THE SECURITIES ACT) IN A TRANSACTION EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES
ACT, (II) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (III) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (III)
IN ACCORDANCE WITH ANY APPLICABLE

  

 -54- 








 
SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE RESALE
RESTRICTIONS REFERRED TO IN (A) ABOVE.” 
 No fractional shares of Common Stock shall be issued 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 which 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, with any fractional share of Common Stock that would have been issuable upon the conversion of any Security or Securities, rounded up to the
nearest whole share of Common Stock. 
 The Company covenants that all shares of Common Stock delivered upon
conversion of the Securities shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free of any lien or adverse claim. 
 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, if any, and will list or cause to be approved for listing or included for quotation, as the case may be, such shares of Common Stock on each national securities exchange or in the
over-the-counter market or such other market on which the Common Stock is then listed or quoted. 
 SECTION
10.06.    Adjustment of Conversion Rate. The conversion rate (the “Conversion Rate”) shall be the initial conversion rate set forth in paragraph 8 of the form of Security attached hereto as
Exhibit A-1 and shall be adjusted from time to time by the Company if any of the following events occurs: 
 (a)    If the Company, at any time or from time to time while any of the Securities are outstanding, exclusively issues shares of Common Stock as a dividend or distribution on shares
of Common Stock, or if the Company effects a share split or share combination, then the Conversion Rate will be adjusted based on the following formula 
  

							
	CR’=	 		 	 CR0xOS’
	 	
	 	 	OS0	 	

 where 
  

					
	 CR0
	 	 =
	 	 the Conversion Rate in effect immediately prior to the Ex-Date of such dividend or distribution, or the effective date of such share split or share combination,
as applicable;

			
	 CR’
	 	 =
	 	 the Conversion Rate in effect immediately after such Ex-Date or effective date;


  

 -55- 









					
	 OS0
	 	 =
	 	 the number of shares of Common Stock outstanding immediately prior to such Ex-Date or effective date; and

			
	 OS’
	 	 =
	 	 the number of shares of Common Stock outstanding immediately after such Ex-Date or effective date.


 Such adjustment shall become effective immediately after the opening of business on the day following the record date for
such dividend or distribution, or the date fixed for determination for such share split or share combination. If any dividend or distribution of the type described in this Section 10.06(a) is declared but not so paid or made, the Conversion
Rate shall again be adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared. 
 (b)    If the Company, at any time or from time to time while any of the Securities are outstanding, issues to all holders of Common Stock any rights or warrants entitling them for a
period of not more than 60 calendar days to subscribe for or purchase shares of Common Stock at a price per share less than the average of the Last Reported Sale Prices of Common Stock for the 10 consecutive Trading Day period ending on the Business
Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be adjusted based on the following formula (provided that the Conversion Rate will be readjusted to the extent such rights or warrants are not
exercised prior to their expiration): 
  

					
	CR’= CR0 x	  	 OS0 + X
	  	
	  	OS0 + Y	  	

 where 
  

					
	 CR0
	 	 =
	 	 the Conversion Rate in effect immediately prior to the Ex-Date for such issuance;

			
	 CR’
	 	 =
	 	 the Conversion Rate in effect immediately after such Ex-Date;

			
	 OS0
	 	 =
	 	 the number of shares of Common Stock outstanding immediately after such Ex-Date;

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

			
	 Y
	 	 =
	 	 the number of shares of Common Stock equal to the aggregate price payable to exercise such rights divided by the average of the Last Reported Sale Prices of
Common Stock for the 10 consecutive Trading Day period ending on the Business Day immediately preceding the date of announcement of the issuance of such rights.


  

 -56- 








 To the extent such rights or warrants are not exercised prior to their
expiration or termination, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number
of shares of Common Stock actually delivered. In the event that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if the date fixed for the determination of
stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than the average of the Last Reported Sale
Prices of Common Stock for the 10 consecutive Trading Day period ending on the Business Day immediately preceding the date of announcement of such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall
be taken into account any consideration received for such rights or warrants and the value of such consideration, if other than cash, as shall be determined in good faith by the Board of Directors of the Company. 
 For the purposes of this Section 10.06(b), rights or warrants distributed by the Company to all holders of Common Stock
entitling them to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (a “Trigger Event”):
(i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this
Section 10.06(b), (and no adjustment to the Conversion Rate under this Section 10.06(b) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and
an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 10.06(b). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are
subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of Indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be
the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any
distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an
adjustment to the Conversion Rate under this Section 10.06(b) was made, (x) in the case of any such rights or warrants which shall all have been redeemed or purchased without exercise by any holders thereof, the Conversion Rate shall be
readjusted upon such final purchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder of Common Stock with
respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all applicable holders of Common Stock as of the date of such redemption or purchase, and (y) in the case of such rights or warrants which
shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 
  


 -57- 








 (c)    If the Company, at any time or
from time to time while the Securities are outstanding, distributes shares of any class of Capital Stock of the Company, evidences of Indebtedness or other assets or property of the Company to all holders of its Common Stock, excluding:
(i) dividends or distributions referred to in Section 10.06(a); (ii) rights or warrants referred to in Section 10.06(b); (iii) dividends or distributions paid exclusively in cash; and (iv) Spin-Offs (as defined below)
to which the provisions set forth below in this Section 10.06(c) shall apply; then the Conversion Rate will be adjusted based on the following formula: 
  

					
	CR’= CR0 x	 	 SP0
	 	
	 	SP0 – FMV	 	

 where 
  

					
	 CR0
	 	 =
	 	 the Conversion Rate in effect immediately prior to the Ex-Date for such distribution;

			
	 CR’
	 	 =
	 	 The Conversion Rate in effect immediately after such Ex-Date;

			
	 SP0
	 	 =
	 	 the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading-Day period ending on the Business Day immediately preceding the
Ex-Date for such distribution; and

			
	 FMV
	 	 =
	 	 the Fair Market Value (as determined by the Board of Directors of the Company) of the shares of Capital Stock, evidences of Indebtedness, assets or property
distributed with respect to each outstanding share of the Common Stock on the Record Date for such distribution.


 Such adjustment shall become effective immediately prior to the opening of business on the day following the record date for such distribution. If the Board of Directors of the Company determines the Fair
Market Value of any distribution for purposes of this Section 10.06(c) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing
the average of the Last Reported Sale Prices of the Common Stock. 
 With respect to an
adjustment pursuant to this Section 10.06(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or
other business unit (a “Spin-Off”), the Conversion Rate in effect immediately before 5:00 p.m., New York City time, on the effective date of the Spin-Off shall be increased based on the following formula: 
  

					
	CR’= CR0 x	 	 FMV0 + MP0
	 	
	 	MP0	 	

  

 -58- 








 where 
  

					
	 CR0
	 	 =
	 	 the Conversion Rate in effect immediately prior to the effective date of the adjustment;

			
	 CR’
	 	 =
	 	 the Conversion Rate in effect immediately after the effective date of the adjustment;

			
	 FMV0
	 	 =
	 	 the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of
Common Stock over the first ten consecutive Trading Day period after the effective date of the Spin-Off; and

			
	 MP0
	 	 =
	 	 the average of the Last Reported Sale Prices of Common Stock over the first ten consecutive Trading Day period after the effective date of the
Spin-Off.


 The adjustment to the Conversion Rate under the preceding
paragraph will occur on the tenth Trading Day from, and including, the effective date of the Spin-Off; provided that in respect of any conversion within the 10 Trading Days following the effective date of any Spin-Off, references within this
Section 10.06(c) to “10 days” shall be deemed replaced with such lesser number of Trading Days as have elapsed between the effective date of such Spin-Off and the Conversion Date in determining the applicable Conversion Rate.

 (d)    If any cash dividend or other distribution is made to all holders
of Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  

					
	CR’= CR0 x	 	 SP0
	 	
	 	SP0 – C	 	

 where 
  

					
	 CR0
	 	 =
	 	 the Conversion Rate in effect immediately prior to the Ex-Date for such distribution;

			
	 CR’
	 	 =
	 	 the Conversion Rate in effect immediately after the Ex-Date for such distribution;

			
	 SP0
	 	 =
	 	 the Last Reported Sale Price of a share of Common Stock on the Trading Day immediately preceding the Ex-Date for such distribution; and

			
	 C
	 	 =
	 	 the amount in cash per share the Company distributes to holders of Common Stock.


  

 -59- 








 (e)    If the Company or any Subsidiary
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 Last Reported Sale Price per share of
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 Conversion Rate shall be increased based on the following formula: 
  

					
	CR’= CR0 x	 	 AC + (SP’ x OS’)
	 	
	 	OS0 x SP’	 	

 where 
  

					
	 CR0
	 	 =
	 	 the Conversion Rate in effect on the date the tender or exchange offer expires;

			
	 CR’
	 	 =
	 	 the Conversion Rate in effect on the day next succeeding the date the tender or exchange offer expires;

			
	 AC
	 	 =
	 	 the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares 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;

			
	 OS’
	 	 =
	 	 the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires; and

			
	 SP’
	 	 =
	 	 the average of the Last Reported Sale Prices of Common Stock over the 10 consecutive Trading Day period commencing on the Trading Day next succeeding the date
such tender or exchange offer expires.


 The adjustment to the Conversion Rate
under this Section 10.06(e) shall occur on the tenth Trading Day from, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within the 10 Trading Days
beginning on the Trading Day next succeeding the date the tender or exchange offer expires, references within this Section 10.06(e) to “10 days” shall be deemed replaced with such lesser number of Trading Days as have elapsed between
the Trading Day next succeeding the date the tender or exchange offer expires and the Conversion Date in determining the applicable Conversion Rate. 
 If the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from

  

 -60- 








 
effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange had
not been made. 
 (f)    As used in this Section 10.06,
“Ex-Date” shall mean the first date on which the shares of the Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive the issuance or distribution in question. 
 (g)    For purposes of this Section 10.06, “record date” shall mean, with
respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or
converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors of the Company
or by statute, contract or otherwise). 
 (h)    All calculations under this
Article X shall be made by the Company. 
 (i)    For purposes of this
Section 10.06, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock 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. 
 (j)    Notwithstanding the foregoing, if the application of the foregoing formulas would result in a decrease in the Conversion Rate (other than as a result of a
reverse stock split or a stock combination), no adjustment to the Conversion Rate (or the Conversion Price) shall be made. 
 (k)    In any case in which this Section 10.06 shall require that an adjustment be made immediately following a record date established for purposes of Section 10.06, the
Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate described in Section 10.06) issuing to the holder of any Security converted after such record date the shares
of Common Stock and other Capital Stock of the Company issuable upon such conversion over and above the shares of Common Stock and other Capital Stock of the Company issuable upon such conversion only on the basis of the Conversion Price prior to
adjustment; and, in lieu of the shares the issuance of which is so deferred, the Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence of the right to receive such shares. 
 (l)    If after an adjustment a Holder of a Security upon conversion of such Security
may receive shares of two or more classes of Capital Stock of the Company, the Conversion Price shall thereafter be subject to adjustment upon the

  

 -61- 








 
occurrence of an action taken with respect to any such class of Capital Stock as is contemplated by this Article X with respect to the Common Stock, on terms comparable to those applicable to
Common Stock in this Article X. 
 (m)    Company shall not take any action
which would result in a change in the Conversion Rate (and the proportionate change in the limitation on the issuance of shares of Common Stock in respect of the Securities pursuant to Section 10.16), unless the Company can thereafter issue
shares of Common Stock up to such the limitation set forth in Section 10.16 as so adjusted without violating a rule or regulation of the Principal Market on which the Common Stock is then listed. 
 SECTION 10.07.    No Adjustment. 
 (a)    No adjustment to the Conversion Rate (or the Conversion
Price) will be required unless the adjustment would require an increase or decrease of at least 1% of the Conversion Rate. If the adjustment is not made because the adjustment does not change the Conversion Rate by at least 1%, then the adjustment
that is not made will be carried forward and taken into account in any future adjustment. All calculations under this Article X will be made to the nearest cent or to the nearest 1/1,000th of a share of Common Stock, as the case may be. 
 (b)    No adjustment to the Conversion Rate shall be made pursuant to Section 10.06
if the Holders of the Securities may participate in the transaction (based on the Conversion Rate or the Conversion Price) that would otherwise give rise to an adjustment pursuant to Section 10.06 without having to convert their Securities;
provided that an adjustment shall be made at such time as the Holders are no longer entitled to participate. 
 (c)    Notwithstanding anything to the contrary in this Article X, no adjustment to the Conversion Rate (or the Conversion Price) shall be made: 
 (i)    upon the issuance of any shares of Common Stock pursuant to any present or future
plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 
 (ii)    upon 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 or program of or assumed by the Company or any Subsidiary; 
 (iii)    upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described
in clause (ii) above outstanding as of the date of this Indenture; 
 (iv)    for a change in the par value of the Common Stock or a change to no par value of the Common Stock; 
  

 -62- 








 (v)    for accrued and unpaid interest,
including Liquidated Damages, if any; or 
 (vi)    to the extent that the
Securities become convertible into cash in accordance with the terms and conditions of this Indenture and the Securities, no adjustment need be made thereafter as to the cash, and interest will not accrue on the cash. 
 (d)    No adjustment to the Conversion Rate (or the Conversion Price) shall be made for
the Company’s issuance of Common Stock or securities convertible into or exchangeable for shares of Common Stock or rights to purchase Common Stock or convertible or exchangeable securities, other than as provided in this Article X. 

SECTION 10.08.    Equivalent Adjustments. In the event that, as a result of an adjustment made
pursuant to Section 10.06 above, the Holder of any Security thereafter surrendered for conversion shall become entitled to receive any shares of Capital Stock of the Company other than shares of its Common Stock, thereafter the Conversion Rate
(and the Conversion Price) for such other shares so receivable upon conversion of any Securities shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common
Stock contained in this Article X. 
 SECTION 10.09.    Adjustment for Tax Purposes.
The Company shall be entitled to make such increases in the Conversion Rate (and resulting reductions in the Conversion Price), in addition to any adjustments made pursuant to Section 10.06, as the Board of Directors of the Company considers to
be advisable in order that any stock dividends, subdivision of shares, distribution of rights to purchase stock or securities, or a distribution or securities convertible into or exchangeable for shares of Common Stock or other Capital Stock
hereafter made by the Company to its stockholders shall not be taxable or such tax shall be diminished. 
 SECTION 10.10.    Notice of Adjustment. Whenever the Conversion Rate (or the Conversion Price) is adjusted, the Company shall promptly file with the Trustee and any Conversion Agent an Officers’ Certificate
setting forth the Conversion Rate and the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment and file a Current Report on Form 8-K with the SEC to disclose such adjustment and such
statement. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate at the Corporate Trust Office of the Trustee, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion
Rate and the Conversion Price and may assume without inquiry that the last Conversion Rate and Conversion Price of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such
adjustment of the Conversion Rate and the Conversion Price setting forth the adjusted Conversion Rate and the adjusted Conversion Price and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the
Conversion Rate and the Conversion Price to each Securityholder at such Holder’s last address appearing on the list of Securityholders provided for in Section 2.05, within 20 days after execution thereof. Failure to deliver such notice
shall not affect the legality or validity of any such adjustment. 
  

 -63- 








 SECTION 10.11.    Notice of Certain Transactions.
In case: 
 (a)    the Company shall declare a dividend (or any other
distribution) on its Common Stock (other than in cash out of retained earnings); or 
 (b)    the Company shall authorize the granting to the holders of its Common Stock of rights, warrants or options to subscribe for or purchase any share of any class or any other rights, warrants or options; or

 (c)    of any reclassification of the Common Stock of the Company (other
than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation, merger, or share exchange to which the Company is a party
and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or 
 (d)    of the voluntary or involuntary dissolution, liquidation or winding-up of the Company; 
 the Company shall cause to be filed with the Trustee and the Conversion Agent and to be mailed to each Holder of Securities
at its address appearing on the list provided for in Section 2.05, as promptly as possible but in any event at least fifteen days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution or rights, warrants or options, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be
determined, or (y) the date on which such reclassification, consolidation, merger, share exchange, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, share exchange, sale, transfer, dissolution, liquidation or
winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, share exchange, transfer, dissolution, liquidation or
winding-up. 
 SECTION 10.12.    Effect of Reclassification, Consolidation, Merger, Share
Exchange or Sale on Conversion Privilege. If any of the following shall occur, namely: (i) any reclassification or change of outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination); (ii) any consolidation, combination, merger or share exchange to which the Company is a party other than a merger in which the Company is the continuing corporation and
which does not result in any reclassification of, or change (other than a change in name, or par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in, outstanding shares of
Common Stock; or (iii) any sale or conveyance of all or substantially all of the assets of the Company, then the Company, or such successor or purchasing corporation, as the case may be, shall, as a condition precedent to such

  

 -64- 








 
reclassification, change, consolidation, merger, share exchange, sale or conveyance, execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then
outstanding shall have the right to convert such Security into the kind and amount of shares of Capital Stock and other securities and property (including cash) receivable upon such reclassification, change, consolidation, merger, share exchange,
sale or conveyance by a holder of the number of shares of Common Stock deliverable upon conversion of such Security immediately prior to such reclassification, change, consolidation, merger, share exchange, sale or conveyance. Such supplemental
indenture shall provide for adjustments of the Conversion Price which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Price provided for in this Article X. If, in the case of any such consolidation, merger,
share exchange, sale or conveyance, the stock or other securities and property (including cash) receivable thereupon by a holder of Common Stock includes shares of Capital Stock or other securities and property of a corporation other than the
successor or purchasing corporation, as the case may be, in such consolidation, merger, share exchange, sale or conveyance, 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 of the Company shall reasonably consider necessary by reason of the foregoing. 
 The provisions of this Section 10.12 shall similarly apply to successive consolidations, mergers, share exchanges, sales or conveyances. Notwithstanding the foregoing, a
distribution by the Company to all holders of its Common Stock for which an adjustment to the Conversion Price or provision for conversion of the Securities may be made pursuant to Section 10.06 shall not be deemed to be a sale or conveyance of
all or substantially all of the assets of the Company for purposes of this Section 10.12. 
 In the event
the Company shall execute a supplemental indenture pursuant to this Section 10.12, the Company shall promptly file with the Trustee an Opinion of Counsel stating that such supplemental indenture is authorized or permitted by this Indenture and
an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or securities or property (including cash) receivable by Holders of the Securities upon the conversion of their Securities after any such
reclassification, change, consolidation, merger, share exchange, sale or conveyance, any adjustment to be made with respect thereto and that all conditions precedent have been complied with. 
 SECTION 10.13.    Trustee’s Disclaimer. The Trustee has no duty to determine any
calculations in this Article X nor shall it have any duty to determine when an adjustment under this Article X should be made, how it should be made or what such adjustment should be made, but may accept as conclusive evidence of the correctness of
any such adjustment, and shall be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 10.10. The Trustee shall not be accountable for and
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 X. Each
Conversion Agent (other than the Company or an Affiliate of the Company) shall have the same protection under this Section 10.13 as the Trustee. 
  

 -65- 








 The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed pursuant to Section 10.12, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officers’ Certificate
with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 10.12. 
 SECTION 10.14.    Voluntary Increase of the Conversion Rate. The Company from time to time may increase the Conversion Rate (and thereby reduce the Conversion Price) by any amount for a period of at least 20 days
and the Board of Directors of the Company shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased (and the Conversion Price
reduced) pursuant to this Section 10.14, a notice of the increase in the Conversion Rate and resulting decrease in the Conversion Price must be disclosed in accordance with Section 10.10 and must be mailed to Holders at least 15 days prior
to the date the increased Conversion Rate and decreased Conversion Price takes effect, which notice shall state the increased Conversion Rate, the decreased Conversion Price and the period during which such Conversion Rate and Conversion Price will
be in effect. 
 SECTION 10.15.    Simultaneous Adjustments. If more than one event
requiring adjustment pursuant to this Article X shall occur before completing the determination of the Conversion Rate and the Conversion Price for the first event requiring such adjustment, then the Board of Directors (whose determination
shall, if made in good faith, be conclusive) shall make such adjustments to the Conversion Rate (and the calculation thereof) after giving effect to all such events as shall preserve for Securityholders the Conversion Rate and Conversion Price
protection provided in this Article X. 
 SECTION 10.16.    Limitation on Conversion
and Issuance of Shares. Notwithstanding anything to the contrary set forth in this Indenture or in the Securities, the maximum number of shares of Common Stock which can be issued in respect of the Securities upon conversion (whether pursuant to
Article X or upon a Mandatory Conversion), Restricted Interest, Make Whole Premium or otherwise shall be limited to 201,880,000 shares of Common Stock in the aggregate for $70,000,000 in aggregate Principal Amount of Securities as of the date
of this Indenture. The limitation set forth in this Section 10.16 shall be adjusted to reflect any adjustments in the Conversion Rate to be made in accordance with this Article X, and shall apply pro rata to all Securities issued under this
Indenture. To the extent any shares of Common Stock are restricted from being issued to a Securityholder in respect of such limitation, the Securityholder shall not receive any cash or other consideration in lieu of such shares. This limitation
shall terminate and cease to be of force and effect if the holders of the Common Stock of the Company approve the termination of such limitation. The Company covenants and agrees to disclose in its Quarterly Reports on Form 10-Q and its Annual
Report on Form 10-K to be filed with the SEC from and after the date of this Indenture so long as any Securities remain outstanding, which disclosure will set forth the then outstanding aggregate principal amount of the Securities and the
maximum number of shares of Common Stock which may be issued in connection therewith after taking into account any conversions of Securities and the payment of Restricted Interest and the Make Whole Premium as of the end of the fiscal period to
which such report relates and, to the extent available, as of a more recent date for which such information is available at the time such report is filed with the SEC.

 ARTICLE XI 
 GUARANTEES 
 SECTION 11.01. Guarantees.

 (a)    For good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, each of the Guarantors hereby jointly and severally and irrevocably and unconditionally guarantees to the Trustee and to each Holder of a Security authenticated and delivered by the Trustee irrespective of the
validity or enforceability of this Indenture or the Securities or the Obligations of the Company and the Guarantors under this Indenture, that: (i) the principal of, premium, if any, and any interest on the Securities (including, without
limitation, any interest that accrues after the filing of a proceeding of the type described in Sections 6.01(e) and (f), Restricted Interest and Make Whole Premium), Liquidated Damages, if any, on the Securities and any fees, expenses and other
amounts owing under this Indenture will be duly and punctually paid in full when due, whether at Stated Maturity, by acceleration, call for Mandatory Conversion, upon a Fundamental Change Offer, purchase or otherwise, and interest on the overdue
principal and (to the extent permitted by law) interest, if any, on the Securities and any other amounts due in respect of the Securities, and all other Obligations of the Company and the Guarantors to the Holders of the Securities and to the
Trustee under this Indenture and the Securities, whether now or hereafter existing, will be promptly paid in full or performed, all strictly in accordance with the terms hereof and of the Securities; and (ii) in case of any extension of time of
payment or renewal of any Securities or any of such other Obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration, call for
Mandatory Conversion, upon a Fundamental Change Offer, purchase or otherwise. If payment is not made when due of any amount so guaranteed for whatever reason, each Guarantor shall be jointly and severally obligated to pay the same individually
whether or not such failure to pay has become an Event of Default which could cause acceleration pursuant to Section 6.02. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. An Event of Default under
this Indenture or the Securities shall constitute an Event of Default under this Guarantee, and shall entitle the Holders to accelerate the Obligations of each Guarantor hereunder in the same manner and to the same extent as the Obligations of the
Company. This Guarantee is intended to be superior to or pari passu in right of payment with all indebtedness of the Guarantors and each Guarantor’s Obligations are independent of any Obligation of the Company or any other Guarantor.

 (b)    Each Guarantor waives presentation to, demand of, payment from and
protest to the Company of any of the Obligations under this Indenture or the Securities and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Obligations. The Obligations of each
Guarantor hereunder shall not be affected by (a) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Securities or any other
agreement or otherwise; (b) any extension or renewal of any guarantee thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the

  

 -67- 








 
Securities or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Obligations or any of them; (e) the failure of any Holder or the Trustee to
exercise any right or remedy against any other guarantor of the Obligations; or (f) any change in the ownership of such Guarantor. 
 (c)    The Obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release,
surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations of the Company or otherwise.
Without limiting the generality of the foregoing, the Obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy
under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Obligations of the Company, or by any other act or thing or
omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity. 
 (d)    Each Guarantor further agrees that its Guarantee herein shall continue to be
effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of, premium, if any, on or interest and Liquidated Damages, if any, on any Obligation of the Company is rescinded or must otherwise be restored
by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise. 
 (e)    In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay the
principal of, premium, if any, on or interest on any Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Obligation, each Guarantor hereby
promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (i) the unpaid amount of such Obligations, (ii) accrued and
unpaid interest on such Obligations (but only to the extent not prohibited by law) and (iii) all other monetary Obligations of the Company to the Holders and the Trustee. 
 (f)    Until such time as the Securities and the other Obligations of the Company
guaranteed hereby have been satisfied in full, each Guarantor hereby irrevocably waives any claim or other rights that it may now or hereafter acquire against the Company or any other Guarantor that arise from the existence, payment, performance or
enforcement of such Guarantor’s Obligations under this Guarantee, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the
Holders or the Trustee against the Company or any other Guarantor or any security, whether or not such

  

 -68- 








 
claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Company or any other Guarantor, directly or
indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right. If any amount shall be paid to such Guarantor in violation of the preceding sentence at any time prior to the
later of the payments in full of the Securities and all other amounts payable under this Indenture, this Guarantee and the Stated Maturity of the Securities, such amount shall be held in trust for the benefit of the Holders and the Trustee and shall
forthwith be paid to the Trustee to be credited and applied to the Securities and all other amounts payable under this Guarantee, whether matured or unmatured, in accordance with the terms of this Indenture, or to be held as security for any
Obligations or other amounts payable under this Guarantee thereafter arising. 
 (g)    Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 11.01 is knowingly
made in contemplation of such benefits. Each Guarantor further agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (x) subject to this Article XI, the maturity of the Obligations guaranteed
hereby may be accelerated as provided in Article VI for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (y) in the event
of any acceleration of such Obligations guaranteed hereby as provided in Article VI, such Obligations (whether or not due and payable) shall further then become due and payable by the Guarantors for the purposes of this Guarantee. 
 (h)    A Guarantor that makes a distribution or payment under a Guarantee shall be
entitled to contribution from each other Guarantor in a pro rata amount based on the Adjusted Net Assets of each such other Guarantor for all payments, damages and expenses incurred by that Guarantor in discharging the Company’s obligations
with respect to the Securities and this Indenture or any other Guarantor with respect to its Guarantee, so long as the exercise of such right does not impair the rights of the Holders of the Securities under the Guarantees. 
 (i)    Each Guarantor also agrees to pay any and all costs and expenses (including
reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section. 
 SECTION 11.02.    Limitation on Liability. 
 Any term or provision of this
Indenture to the contrary notwithstanding, the maximum aggregate amount of the Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to
such Guarantor, void, voidable or unenforceable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. To effectuate the foregoing intention, the Obligations of each
Guarantor shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by

  

 -69- 








 
or on behalf of any other Guarantor in respect of the Obligations of such other Guarantor under its Guarantee or pursuant to its contribution Obligations hereunder, result in the Obligations of
such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law or otherwise not being void, voidable or unenforceable under any bankruptcy, reorganization, receivership, insolvency,
liquidation or other similar legislation or legal principles under any applicable foreign law. Each Guarantor that makes a payment or distribution under a Guarantee shall be entitled to a contribution from each other Guarantor in a pro rata amount
based on the Adjusted Net Assets of each Guarantor. 
 SECTION 11.03.    Execution and
Delivery of Guarantees. 
 To further evidence its Guarantee set forth in Section 11.01 hereof, each
Guarantor hereby agrees that notation of such Guarantee shall be endorsed on each Security authenticated and delivered by the Trustee and executed by either manual or facsimile signature of an authorized officer of such Guarantor. Each Guarantor
hereby agrees that its Guarantee set forth in Section 11.01 hereof shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Guarantee. If an officer of a Guarantor whose signature is on
this Indenture or a Security no longer holds that office at the time the Trustee authenticates such Security or at any time thereafter, such Guarantor’s Guarantee of such Security shall be valid nevertheless. The delivery of any Security by the
Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in this Indenture on behalf of the Guarantor. 
 SECTION 11.04.    When a Guarantor May Merge, etc. 
 No Guarantor shall consolidate with or merge with or into (whether or not such Guarantor is the surviving person) another corporation, Person or entity whether or not affiliated with such Guarantor (but
excluding any consolidation, amalgamation or merger if the surviving corporation is no longer a Subsidiary) unless (i) subject to the provisions of Section 11.07 hereof, the Person formed by or surviving any such consolidation or merger
(if other than such Guarantor) assumes all the Obligations of such Guarantor pursuant to a supplemental indenture in form reasonably satisfactory to the Trustee under the Securities and this Indenture and (ii) immediately after giving effect to
such transaction, no Default or Event of Default exists. In connection with any such consolidation or merger, the Trustee shall be entitled to receive an Officers’ Certificate and an Opinion of Counsel stating that such consolidation or merger
is permitted by, and is being consummated in compliance with, this Section 11.04, and if a supplemental indenture is required in connection with such consolidation or merger, that such supplemental indenture complies with the requirements of
this Indenture. 
 SECTION 11.05.    No Waiver. 
 Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege
under this Article XI shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders
herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article XI at law, in equity, by statute or otherwise. 
  

 -70- 








 SECTION 11.06.    Modification. 
 No modification, amendment or waiver of any provision of this Article XI, nor the consent to any departure by any
Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or
demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances. 
 SECTION 11.07.    Release of Guarantor. 
 Upon the sale or other transfer of all or substantially all of the Capital Stock or all or substantially all of the assets of a Guarantor to any Person that is not an Affiliate of the Company in compliance with the terms of this Indenture
(including, without limitation, Section 11.04 hereof) and in a transaction that does not result in a Default or an Event of Default being in existence or continuing immediately thereafter, such Guarantor shall be deemed automatically and
unconditionally released and discharged from all obligations under this Indenture without any further action required on the part of the Trustee or any Holder; provided that the Company or another Guarantor receives consideration for such
Capital Stock or assets in an amount equal to the Fair Market Value of such Capital Stock or assets. The Trustee shall deliver at the expense of the Company an appropriate instrument or instruments evidencing such release upon receipt of a request
of the Company accompanied by an Officers’ Certificate and Opinion of Counsel certifying as to the compliance with this Section 11.07 and the other applicable provisions of this Indenture. 
 SECTION 11.08.    Execution of Supplemental Indentures for Future Guarantors. 
 Any Domestic Subsidiary that guarantees any debt securities of the Company (excluding any Financing Facility or any other
bank credit facility) is required to become a Guarantor (but only so long as such other guarantees continue in effect) and the Company shall cause each such Subsidiary to promptly execute and deliver to the Trustee a supplemental indenture in the
form of Exhibit C hereto pursuant to which such Subsidiary shall become a Guarantor under this Article XI and shall guarantee the Obligations of the Company under the Securities and this Indenture. Concurrently with the execution
and delivery of such supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary and that, subject to the
application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, and subject to other exceptions reasonably satisfactory to the
Trustee, whether considered in a proceeding at law or in equity, the Guarantee of such Guarantor is a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms, and as to any such other
matters as the Trustee may reasonably request.

 Any certificate or opinion of an Officer of the Company may be based, insofar as it
relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such Officer knows, or in the exercise of reasonable case should know, that the certificate or opinion or representations with respect to the matters
upon which his or her certificate or opinion is based are erroneous. Any such certificate or opinion of counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers
of the Company stating the information on which counsel is relying unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by
law, in such federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other or in any other manner
provided by law. Nothing in this Indenture shall affect any right that any Holder may otherwise have to bring any action or proceeding relating to this Indenture, the Securities and the Guarantees against the Company, the Guarantors or their

 [FORM OF REVERSE SIDE OF NOTE] 
 YRC WORLDWIDE INC. 
 6% Convertible Senior Notes due 2014

  

	 	1.	 Interest. 


 This Security shall accrue interest at an initial rate of 6% per annum. The Company promises to pay interest on the Securities in cash semiannually on each February 15 and August 15,
commencing August 15, 2010, to Holders of record on the immediately preceding February 1 and August 1, respectively, whether or not such day is a Business Day. Interest on the Securities will accrue from the most recent date to which
interest has been paid, or if no interest has been paid, from February 23, 2010, until the Principal Amount is paid or duly made available for payment. The Company will pay interest on any overdue Principal Amount at the interest rate borne by
the Securities at the time such interest on the overdue Principal Amount accrues, compounded semiannually, and it shall pay interest on overdue installments of interest and Liquidated Damages, if any (without regard to any applicable grace period),
at the same interest rate compounded semiannually. Interest on the Securities will be computed on the basis of a 360-day year comprised of twelve 30-day months. Upon the occurrence and during the continuation of an Event of Default, the interest
rate applicable hereunder shall be increased by 2% per annum. 
 Notwithstanding the foregoing, and
provided that the payment of the interest in shares of Common Stock would not result in a violation or violations of the limitation on conversion set forth in Section 10.16 of the Indenture, to the extent that (i) the Company is not
permitted to pay the entire amount of interest then due and payable on this Security and the other Securities issued pursuant to the Indenture (such amount of interest that is not paid in cash, “Bank Restricted Interest”) pursuant to the
terms of any Financing Facility as in effect of the date of the Indenture or (ii) the Company and its Subsidiaries, collectively, determine in their reasonable judgment that they lack sufficient funds to necessary to pay the entire amount of
the interest then due and payable on this Security and the other Securities issued pursuant to the Indenture or is otherwise deferring scheduled payments of interest, commitment fees and letter of credit fees any Financing Facility (provided
that the Company and its Subsidiaries would be deemed to have sufficient funds to the extent they had available borrowing capacity under the Financing Facilities or other lines of credit or sources of capital that is permitted to be used for this
purpose) (such amount of interest for which sufficient funds are lacking, together with Bank Restricted Interest, “Restricted Interest”), the Company may elect to pay Restricted Interest due on this Security by issuing shares of Common
Stock that are qualified for registration with the SEC upon the resale of such shares by the holder thereof and listed or quoted on a Principal Market in an amount of shares equal to the quotient of (x) the amount of such Restricted Interest
then due on this Security divided by (y) the Restricted Interest Conversion Price (as hereinafter defined), rounded up to the nearest whole share of Common Stock; provided that such rounding shall be with respect to all Restricted
Interest then due to the Holder under this Security and any other Securities owned by the Holder. On or prior to the record date immediately preceding the interest payment date for which Restricted Interest will be paid, the Company must give
written notice to the Trustee and file a Current Report on Form 8-K of its intention to issue shares of

  

 A-1-4 








 
Common Stock in respect of Restricted Interest and the amount of Restricted Interest per $1,000 in principal amount of Securities. 
 For the purposes hereof, (i) “Principal Market” shall mean The NASDAQ Global Select
Market or such other stock exchange or electronic quotation system on which the Common Stock is listed or quoted as of the applicable Trading Day; (ii) “Restricted Interest Conversion Price” shall mean the product of (x) 95%
multiplied by (y) the simple arithmetic average of the Weighted Average Price of the shares of Common Stock (as reported by Bloomberg) for each of the five (5) consecutive Trading Days ending on the second (2nd) Trading Day immediately preceding the interest payment date to
which such Restricted Interest relates; provided that in no event shall the Restricted Interest Conversion Price be less than $0.38 per share of Common Stock (as appropriately adjusted for any stock dividend, stock split, stock combination or
other similar transaction) or greater than the Conversion Price then in effect; and (iii) “Weighted Average Price” shall mean for the Common Stock as of any date, the dollar volume-weighted average price for the Common Stock on the
Principal Market during the period beginning at 9:30:01 a.m., New York City time (or such other time as the Principal Market publicly announces as the official open of trading), and ending at 4:00:00 p.m., New York City time (or such other
time as the Principal Market publicly announces is the official close of trading) as reported by Bloomberg through its “Volume at Price” function, or, if the foregoing does not apply, the dollar volume-weighted average price of the Common
Stock in the over-the-counter market on the electronic bulletin board for such security during the period beginning at 9:30:01 a.m., New York City time (or such other time as such market publicly announces is the official open of trading), and
ending at 4:00:00 p.m., New York City time (or such other time as such market publicly announces is the official close of trading) as reported by Bloomberg, or, if no dollar volume-weighted average price is reported for the Common Stock by
Bloomberg for such hours, the average of the highest closing bid price and the lowest closing ask price of any of the market makers for the Common Stock as reported in the “pink sheets” by Pink Sheets LLC (formerly the National Quotation
Bureau, Inc.); provided that if the Weighted Average Price cannot be calculated for the Common Stock on a particular date on any of the foregoing bases, the Weighted Average Price of the Common Stock on such date shall be the Fair Market
Value as reasonably determined by the Board of Directors of Company acting in good faith, with all such determinations to be appropriately adjusted for any stock dividend, stock split, stock combination or other similar transaction. 
  

	 	2.	 Method of Payment. 


 The Company will pay interest and Liquidated Damages, if any, on this Security (except defaulted interest) to the Person who is the registered Holder of this Security at the close of business on
February 1 or August 1, as the case may be, next preceding the related interest payment date. Subject to the terms and conditions of the Indenture, the Company will make payments in respect of the Principal Amount of Securities to be
converted in a Mandatory Conversion, the Make Whole Premium, the Fundamental Change Purchase Price and the Principal Amount at Stated Maturity (or such earlier time as may be required following an Event of Default), as the case may be, to the Holder
who surrenders a Security to (x) the Paying Agent with respect to payments in cash in respect of the Fundamental Change Purchase Price and the Principal Amount at Stated Maturity (or such earlier time as may be required following an Event of
Default) or (y) the Conversion Agent with respect to shares of Common Stock to be delivered

  

 A-1-5 








 
in connection with a Mandatory Conversion or the payment of the Make Whole Premium upon the conversion of the Securities pursuant to a Mandatory Conversion or a conversion at the option of the
Holder. The Company will pay all cash amounts due on the Securities in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may pay interest, Liquidated Damages, if any,
Fundamental Change Purchase Price and the Principal Amount at Stated Maturity (or such earlier time as may be required following an Event of Default), as the case may be, to the extent such amounts are permitted by the terms of this Security and the
Indenture to be paid in cash, by check or wire payable in such money; provided, however, that a Holder holding Securities with an aggregate Principal Amount in excess of $1,000,000 will be paid by wire transfer in immediately available
funds at the election of such Holder. The Company may mail an interest check for the payment of cash interest 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 of cash hereon shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. 
  

	 	3.	 Paying Agent, Conversion Agent and Registrar. 


 Initially, U.S. Bank National Association (the “Trustee”) will act as Paying Agent, Conversion Agent and Registrar. The Company may appoint and change any Paying Agent,
Conversion Agent or Registrar without notice, other than notice to the Trustee; provided that the Company will maintain at least one Paying Agent in the State of New York, City of New York, Borough of Manhattan, which shall initially be an
office or agency of the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent or Registrar. 
  

	 	4.	 Indenture. 


 The Company issued the Securities under an Indenture dated as of February 23, 2010 (as amended or supplemented from time to time in accordance with the terms thereof and of this Security, the
“Indenture”), between the Company and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as in effect from time to time (the
“TIA”). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the TIA for a statement
of those terms. 
 The Securities are limited to $70,000,000 aggregate Principal Amount (subject to
Section 2.07 of the Indenture). 
  

	 	5.	 Redemption and Mandatory Conversion at the Option of the Company. 


 No sinking fund is provided for the Securities. The Securities are not redeemable prior to the Stated Maturity;
provided, however, that the Company may elect to cause the Securities to be converted into shares of Common Stock (a “Mandatory Conversion”) from and after the two (2) year anniversary of the date of the Indenture,
whereupon the Securities shall be convertible into shares of Common Stock as a whole, or from time to time in part, in any integral

  

 A-1-6 








 
multiple of $1,000, at the option of the Company, if the Last Reported Sale Price of the Common Stock has been at least 150% of the Conversion Price in effect on the applicable Trading Day for at
least twenty (20) Trading Days during any thirty (30) consecutive Trading Day period ending one Trading Day prior to the date on which the Company announces its election of a Mandatory Conversion in accordance with the requirements of
Section 3.03 of the Indenture, with the number of shares to be issued in connection with such Mandatory Conversion equal to the sum of (x) the Principal Amount of this Security (or portion thereof) subject to such Mandatory Conversion
plus (y) accrued and unpaid Liquidated Damages, if any, on such Principal Amount accruing through but not including the Mandatory Conversion Date, divided by the Conversion Price in effect on the second (2nd) Business Day immediately preceding such Mandatory Conversion
Date (subject to adjustments as set forth in Article X of the Indenture), plus the Make Whole Premium divided by the Make Whole Premium Conversion Price (plus such shares of Common Stock to be issued with respect to
Restricted Interest, if any, to the extent not issued to the Holder of a Security (or portion thereof) subject to such Mandatory Conversion with respect to an interest payment date prior to such Mandatory Conversion Date); provided that, if
the Mandatory Conversion Date is on or after an interest record date but on or prior to the related interest payment date, Liquidated Damages (other than any accrued and unpaid Liquidated Damages paid in shares as provided above), if any, will be
payable to the Holders in whose names the Securities are registered at the close of business on the relevant record date in shares of Common Stock at the Conversion Price; provided, further, in each case, that in lieu of the issuance
of fractional shares of Common Stock, the number of shares of Common Stock to be delivered to the Holder pursuant to this paragraph 5 shall be rounded up to the nearest whole share of Common Stock, and that such rounding shall be with respect
to the sum of all shares of Common Stock issuable to the Holder with respect to all of the Securities (or portions thereof) of the Holder being converted in connection with such Mandatory Conversion or conversion at the option of the Holder. The
date for the issuance of Common Stock in connection with a Mandatory Conversion shall be the fifteenth Trading Day after the date notice of a Mandatory Conversion in given to the Holder pursuant to paragraph 7 below (the “Mandatory
Conversion Date”). 
  

	 	6.	 Purchase by the Company at the Option of the Holder. 


 At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase the Securities held by such Holder after the
occurrence of a Fundamental Change of the Company for a Fundamental Change Purchase Price equal to 100% of the Principal Amount thereof plus accrued and unpaid interest and Liquidated Damages, if any, thereon, accruing up to but not including the
Fundamental Change Purchase Date which Fundamental Change Purchase Price shall be paid in cash. Holders have the right to withdraw any Fundamental Change Purchase Notice by delivering to the Paying Agent a written notice of withdrawal in accordance
with the provisions of the Indenture. 
 If cash sufficient to pay the Fundamental Change Purchase Price and
accrued and unpaid interest and Liquidated Damages, if any, of all Securities or portions thereof to be purchased as of the Fundamental Change Purchase Date is deposited with the Paying Agent on the Business Day following the Fundamental Change
Purchase Date, interest and Liquidated Damages, if any, cease to accrue on such Securities (or portions thereof) immediately after such Fundamental Change Purchase Date, and the Holder thereof shall have no other rights as such

  

 A-1-7 








 
other than the right to receive the Fundamental Change Purchase Price upon surrender of such Security. 
  

	 	7.	 Notice of Mandatory Conversion. 


 Notice of Mandatory Conversion pursuant to paragraph 5 of this Security will be mailed as promptly as practicable, but in no event later than three (3) Business Days, after the date the Company has
announced its election of a Mandatory Conversion in accordance with Section 3.03 of the Indenture. Such notice shall be given to each Holder of Securities to be so converted at the Holder’s registered address. If such number of shares of
Common Stock sufficient to be issued in respect of the Principal Amount of the Securities (or portions thereof), plus accrued and unpaid Liquidated Damages, if any, thereon (accruing to but not including the date of such Mandatory Conversion), to be
converted in such Mandatory Conversion on the Mandatory Conversion Date, and the shares to be issued in respect of the Make Whole Premium and Restricted Interest, if any, thereon, are deposited with the Conversion Agent for issuance and payment on
the Mandatory Conversion Date, immediately after such Mandatory Conversion Date interest (other than past due accrued and unpaid interest) and Liquidated Damages, if any, on the Securities (or portions thereof) to be converted in such Mandatory
Conversion shall cease to accrue. Securities in denominations larger than $1,000 of Principal Amount may be redeemed in part but only in integral multiples of $1,000 of Principal Amount. 
  

	 	8.	 Conversion. 


 A Holder of a Security may convert such Security into shares of Common Stock of the Company in whole or in part, at any time and from time to time. The initial conversion price is $0.43 per share, subject
to adjustment under certain circumstances as described in Article X of the Indenture (the “Conversion Price”), and the initial conversion rate is 2,325.5814 shares of Common Stock per $1,000 in principal amount of Securities.
Subject to the limitations set forth below and in Section 10.16 of the Indenture, the number of shares issuable upon conversion of a Security is determined by dividing the principal amount converted by the Conversion Price in effect on the
Conversion Date plus the number of shares, if any, issuable in respect to the Make Whole Premium. Upon conversion, no adjustment for interest, if any (except for the payment of the Make Whole Premium), or dividends will be made. No fractional shares
will be issued upon conversion; in lieu thereof, the number of shares of Common Stock to be delivered to the Holder pursuant to this paragraph 8 shall be rounded up to the nearest whole share of Common Stock; provided that such rounding
shall be with respect to the sum of all shares of Common Stock issuable to the Holder with respect to all of the Securities (or portions thereof) of the Holder being converted pursuant to a notice of conversion delivered by the Holder to the
Conversion Agent described in the following paragraph on the date of conversion specified in such notice. 
 To
convert a Security, a Holder must (a) complete and sign the conversion notice set forth below and deliver such notice to the Conversion Agent, (b) surrender the Security to the Conversion Agent, (c) furnish appropriate endorsements
and transfer documents if required by the Registrar or the Conversion Agent, (d) pay any transfer or similar tax, if required and (e) if the Security is held in book-entry form, complete and deliver to the Depositary appropriate
instructions pursuant to the Depositary’s book-entry conversion programs. If a Holder surrenders

  

 A-1-8 








 
a Security for conversion between the record date for the payment of an installment of interest and the next interest payment date, the Security must be accompanied by payment of an amount equal
to the interest and Liquidated Damages, if any, payable on such interest payment date on the principal amount of the Security or portion thereof then converted; provided, however, that no such payment shall be required if such Security
has been called for conversion on a Mandatory Conversion Date within the period between and including such record date and such interest payment date, or if such Security is surrendered for conversion on the interest payment date. A Holder may
convert a portion of a Security equal to $1,000 or any integral multiple thereof. 
 A Security in respect of
which a Holder has delivered a Fundamental Change Repurchase Notice exercising the option of such Holder to require the Company to repurchase such Security as provided in Section 3.07 of the Indenture may be converted only if such notice of
exercise is withdrawn as provided above and in accordance with the terms of the Indenture. 
 Notwithstanding
anything herein to the contrary, from the date of the Indenture through (i) but not including the two (2) year anniversary thereof, in no event shall the Holder be entitled to convert any portion of this Security in excess of that portion
of this Security upon conversion of which the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its Affiliates (as defined below) (other than shares of Common Stock which may be deemed beneficially owned
through the ownership of the unconverted portion of the Security or the unexercised or unconverted portion of any other security of the Holder subject to a limitation on conversion analogous to the limitations contained herein in this
clause (i)) and (2) the number of shares of Common Stock issuable upon the conversion of the portion of this Security with respect to which the determination of this proviso is being made (including the payment of the Make Whole Premium in
connection therewith), would result in beneficial ownership by the Holder and its Affiliates of any amount greater than 4.9% of the then outstanding shares of Common Stock (whether or not, at the time of such exercise, the Holder and its Affiliates
beneficially own more than 4.9% of the then outstanding shares of Common Stock), and (ii) and including the Stated Maturity, in no event shall the Holder be entitled to convert any portion of this Security to the extent that such conversion
would cause the Holder to hold or own greater than 9.9% of the total combined voting power of all classes of Voting Stock of the Company within the meaning of Section 871(h)(3)(B) of the Internal Revenue Code of 1986, as amended (the
“Code”), taking into consideration the attribution rules set forth in Section 871(h)(3)(C) of the Code. As used herein, the term “Affiliate” means any person or entity that, directly or indirectly through one or more
intermediaries, controls or is controlled by or is under common control with a person or entity, as such terms are used in and construed under Rule 144 under the Securities Act. For purposes of the proviso to the second preceding sentence,
beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and Regulations 13D-G thereunder, except as otherwise provided in clause (1) of such proviso. The limitations set forth in clause (i) above
may be waived by the Holder upon provision of no less than sixty-one (61) days prior notice to the Company. The limitations set forth in clause (ii) above may not be waived at any time by the Holder. 
  

 A-1-9 









	 	9.	 Denominations; Transfer; Exchange. 


 The Securities are in fully registered form, without coupons, in denominations of $1,000 of Principal Amount and integral multiples of $1,000. A Holder may transfer 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 and fees required by law or permitted by the Indenture. The Registrar need not transfer or
exchange any Securities selected for Mandatory Conversion (except, in the case of a Security to be converted in part, the portion of the Security not to be converted) or any Securities in respect of which a Fundamental Change Purchase Notice has
been given and not withdrawn (except, in the case of a Security to be purchased in part, the portion of the Security not to be purchased). 
  

	 	10.	 Persons Deemed Owners. 


 The registered Holder of this Security may be treated as the owner of this Security for all purposes. 
  

	 	11.	 Unclaimed Money or Securities. 


 The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed

another person. 
  

	 	12.	 Amendment; Waiver. 


 Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in aggregate Principal
Amount of the Securities at the time outstanding and (ii) certain Defaults may be waived with the written consent of the Holders of a majority in aggregate Principal Amount of the Securities at the time outstanding. Subject to certain
exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee may amend the Indenture or the Securities so long as such changes, other than those in clause (ii), do not adversely affect the interest of
Securityholders (i) to cure any ambiguity, omission, defect or inconsistency, (ii) to comply with Article V or Section 10.12 of the Indenture, (iii) to evidence and provide for the acceptance of appointment under the Indenture by
a successor Trustee, or (iv) to comply with any requirement of the SEC in connection with the qualification of the Indenture under the TIA. 
  

	 	13.	 Defaults and Remedies.

such default continues for 30 days; (ii) default in payment of the Principal Amount or Fundamental Change Purchase Price in respect of the Securities when the same becomes due and payable; (iii) failure by the Company in the performance,
or breach, of

  

 A-1-10 








 
any of the Company’s other covenants in the Indenture which are not remedied within 45 days; (iv) defaults by the Company in the payment at final maturity (giving effect to any
applicable grace periods and any extension thereof) of the stated principal amount of any of the Company’s or its Subsidiaries indebtedness, or acceleration of the final stated maturity of any such indebtedness (which acceleration is not
rescinded, annulled or otherwise cured within 10 days of receipt by the Company or such Subsidiary of notice of any such acceleration) if the aggregate principal amount of such indebtedness aggregates $10,000,000 or more at any time; (v) the
Company or a Significant Subsidiary fails to pay when due any final, non-appealable judgment (other than any judgment as to which a reputable insurance company has accepted full liability) aggregating in excess of $15,000,000, which judgments are
not stayed, bonded or discharged within 60 days after its entry; (vi) failure by the Company to issue Common Stock upon conversion of Securities by a Holder or upon a Mandatory Conversion in accordance with the provisions of the Indenture and
the Securities; (vii) a Guarantee by a Guarantor that is a Significant Subsidiary ceases to be or is asserted by the Company or any Guarantor not to be in full force and effect (other than in accordance with the terms of the Indenture and such
Guarantees); and (viii) certain events of bankruptcy or insolvency. 
 Securityholders may not enforce the
Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in
aggregate Principal Amount of the Securities at the time outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of amounts
specified in clause (i) or (ii) above) if it determines that withholding notice is in their interests. 
  

	 	14.	 Trustee Dealings with the Company. 


 Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and
collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
  

	 	15.	 No Recourse Against Others. 


 A director, officer, employee or shareholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 
  

	 	16.	 Authentication. 


 This Security shall not be valid until an authorized signatory of the Trustee manually signs the Trustee’s Certificate of Authentication on the other side of this Security.
