The Notes shall be executed on behalf of the Company by one of its Officers.

Notes bearing the manual or facsimile signatures of individuals who were at any time Officers of the Company shall bind the Company, notwithstanding that such individual has ceased to hold such office prior to the authentication and delivery of such Notes or did not hold such office at the date of such Notes.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes. The Company Order shall specify the amount of Notes to be authenticated, and shall further specify the amount of such Notes to be issued as one or more Global Notes or as one or more Physical Notes. The Trustee in accordance with such Company Order shall authenticate and deliver such Notes as provided in this Indenture and not otherwise.

Each Note shall be dated the date of its authentication.

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein executed by an authorized signatory of the Trustee by manual signature, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder.

Section 2.05 Temporary Notes.

Pending the preparation of Physical Notes, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Notes that are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the Physical Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the Officer executing such Notes may determine, as evidenced by such Officer’s execution of such Notes; provided that any such temporary Notes shall bear legends on the face of such Notes as set forth in the Form of Note attached hereto as Exhibit A and/or Sections 2.07 and 2.11.

After the preparation of Physical Notes, the temporary Notes shall be exchangeable for Physical Notes upon surrender of the temporary Notes at any office or agency of the Company designated pursuant to Section 5.02, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Company shall execute, and the Trustee shall, upon receipt of a Company Order, authenticate and deliver, in exchange therefor a like principal amount of Physical Notes of authorized denominations. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as Physical Notes.

Section 2.06 Registration; Registration of Transfer and Exchange.

(a) The Company shall cause to be kept at the applicable Corporate Trust Office of the Trustee in the continental United States a register (the register maintained in such office and in any other office or agency designated pursuant to Section 5.02 being herein sometimes collectively referred to as the “Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration and transfer of Notes. The Trustee is hereby appointed registrar (the “Registrar”) for the purpose of registering the transfer and exchange of the Notes as herein provided.

Execution Version

Upon surrender for registration of transfer of any Note at an office or agency of the Company designated pursuant to Section 5.02 for such purpose, the Company shall execute, and upon receipt of a Company Order the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination and of a like aggregate principal amount and tenor, each such Note bearing such restrictive legends as may be required by this Indenture (including the Form of Note attached hereto as Exhibit A and Sections 2.07 and 2.11).

At the option of the Holder, and subject to the other provisions of Sections 2.07 and 2.11, Notes may be exchanged for other Notes of any authorized denomination and of a like aggregate principal amount and tenor, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall, upon receipt of a Company Order, authenticate and deliver, the Notes which the Holder making the exchange is entitled to receive.

All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange.

Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. As a condition to the registration of transfer of any Restricted Notes, the Company or the Trustee may require evidence satisfactory to them as to the compliance with the restrictions set forth in the legend on such Notes.

No service charge shall be made for any registration of transfer or exchange of Notes, but the Company and the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Section 2.11 not involving any transfer..

Neither the Company nor the Registrar shall be required to exchange or register a transfer of any Note in the circumstances set forth in Section 2.11(a)(iv).

(b) Neither any members of, or participants in, the Depositary (collectively, the “Agent Members”) nor any other Persons on whose behalf any Agent Member may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, or under any such Global Note, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee, the Agents and any of their respective agents as the absolute owner and Holder of such Global Note for all purposes whatsoever. Neither the Trustee nor any Agent shall have any liability, responsibility or obligation to any Agent Members or any other Person on whose behalf Agent Members may act with respect to (i) any ownership interests in the Global Note, (ii) the accuracy of the records of the Depositary or its nominee, (iii) any notice required hereunder, (iv) any payments under or with respect to the Global Note or (v) actions taken or not taken by any Agent Members.

Execution Version

(c) Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, any Agent or any of their respective agents 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 Note. The registered Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Indenture or the Notes.

Section 2.07 Transfer Restrictions.

(a) Restricted Notes.

(i) Every Note (and any security issued in exchange therefor or substitution thereof) that bears, or that is required under this Section 2.07 to bear, the Restricted Notes Legend will be deemed to be a “Restricted Note” (which, for the avoidance of doubt, shall not include any Exchange Note). Each Restricted Note will be subject to the restrictions on transfer set forth in this Indenture (including in the Restricted Notes Legend) and will bear the restricted CUSIP number for the Notes unless the Company notifies the Trustee in writing that such restrictions on transfer are eliminated or otherwise waived by written consent of the Company (including, without limitation, by the Company’s delivery of the Free Transferability Certificate as provided herein), and each Holder of a Restricted Note, by such Holder’s acceptance of such Restricted Note, will be deemed to be bound by the restrictions on transfer applicable to such Restricted Note.

(ii) Until the Resale Restriction Termination Date, any Note (other than an Exchange Note), will bear the Restricted Notes Legend unless:

(A)

(1) such Note, since last held by the Company or an affiliate of the Company (within the meaning of Rule 144), if ever, was transferred (I) to a Person other than (x) the Company, (y) an affiliate of the Company (within the meaning of Rule 144) or (z) a Person that was an affiliate of the Company (within the meaning of Rule 144) within the 90 days immediately preceding such transfer and (II) pursuant to a registration statement that was effective under the Securities Act at the time of such transfer; or

(2) such Note was transferred (I) to a Person other than (x) the Company or (y) an affiliate of the Company (within the meaning of Rule 144) or a Person that was an affiliate of the Company (within the meaning of Rule 144) within the 90 days immediately preceding such transfer and (II) pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act; and

(B)

the Company delivers written notice to the Trustee and the Registrar (including, without limitation, by the Company’s delivery of the Free Transferability Certificate as provided herein) stating that the Restricted Notes Legend may be removed from such Note and all Applicable Procedures have been complied with.

Execution Version

(iii) In addition, until the Resale Restriction Termination Date, no transfer of any Restricted Note will be registered by the Registrar unless the transferring Holder delivers to the Trustee a completed notice substantially in the form of the Form of Assignment and Transfer, which contains a certification that the transferee is (A) Teligent, Inc. or a subsidiary thereof or (B) such other person that is not an affiliate of the Company (within the meaning of Rule 144) and has not been an affiliate of the Company (within the meaning of Rule 144) within the 90 days immediately preceding the date of such proposed transfer.

(iv) On and after the Resale Restriction Termination Date, any Note will bear the Restricted Note Legend if at any time the Company determines that, to comply with applicable law, such Note must bear the Restricted Notes Legend and the Company notifies the Trustee in writing.

(b) Restricted Stock.

(i) Every share of Common Stock that bears, or that is required under this Section 2.07 to bear, the Restricted Stock Legend will be deemed to be “Restricted Stock”. Each share of Restricted Stock will be subject to the restrictions on transfer set forth in this Indenture (including in the Restricted Stock Legend) and will bear a restricted CUSIP number unless such restrictions on transfer are eliminated or otherwise waived by written consent (including, without limitation, by the Company’s delivery of the Free Transferability Certificate in connection with the Notes as provided herein) of the Company, and each Holder of Restricted Stock, by such Holder’s acceptance of Restricted Stock, will be deemed to be bound by the restrictions on transfer applicable to such Restricted Stock.

(ii) Until the Resale Restriction Termination Date, any shares of Common Stock issued upon the conversion of a Note (other than an Exchange Note), and any shares of Common Stock issued upon conversion of a Restricted Note, will be issued in book-entry form by or on behalf of the Company and will bear the Restricted Stock Legend unless the Company delivers written notice to the transfer agent for the Common Stock stating that such shares of Common Stock need not bear the Restricted Stock Legend.

(iii) On and after the Resale Restriction Termination Date, shares of Common Stock will be issued in book-entry form and will bear the Restricted Stock Legend at any time the Company reasonably determines that, to comply with applicable law, such shares of Common Stock must bear the Restricted Stock Legend.

(c) As used in this Section 2.07, the term “transfer” means any sale, pledge, transfer, loan, hypothecation or other disposition whatsoever of any Restricted Note, any interest therein or any Restricted Stock.

(d) All Notes, whether Global Notes or Physical Notes, are required to bear the Non-Affiliate Legend at all times, whether before or after the Resale Restriction Termination Date.

Execution Version

Section 2.08 Expiration of Restrictions.

(a) Physical Notes. Any Physical Note (or any security issued in exchange or substitution therefor) that does not constitute a Restricted Note may be exchanged for a new Note or Notes of like tenor and aggregate principal amount that do not bear the Restricted Notes Legend required by Section 2.07. To exercise such right of exchange, the Holder of such Note must surrender such Note in accordance with the provisions of Section 2.11 and deliver any additional documentation required by this Indenture in connection with such exchange.

(b) Global Notes; Resale Restriction Termination Date.

(i) If, on the Free Trade Date, or the next succeeding Business Day if the Free Trade Date is not a Business Day, any Notes are represented by a Global Note that is a Restricted Note (any such Global Note, a “Restricted Global Note”), as promptly as practicable, the Company will automatically exchange every beneficial interest in each Restricted Global Note for beneficial interests in Global Notes that do not bear the Restricted Notes Legend and are not subject to the restrictions set forth in the Restricted Notes Legend and in Section 2.07.

(ii) To effect such automatic exchange, the Company will (A) deliver to the Depositary an instruction letter for the Depositary’s mandatory exchange process at least 15 days immediately prior to the Free Trade Date (with a copy to the Trustee) and (B) deliver to each of the Trustee and the Registrar a duly completed Free Transferability Certificate on or promptly after the Free Trade Date. The date of the Free Transferability Certificate will be known as the “Resale Restriction Termination Date”. The Trustee shall assume that the Free Trade Date has not occurred unless and until it receives a Free Transferability Certificate.

(iii) Immediately upon receipt of the Free Transferability Certificate by each of the Trustee and the Registrar:

(A) the Restricted Notes Legend will be deemed removed from each of the Global Notes specified in such Free Transferability Certificate and the restricted CUSIP number will be deemed removed from each of such Global Notes and deemed replaced with the unrestricted CUSIP number;

(B) the Restricted Stock Legend will be deemed removed from any shares of Common Stock previously issued upon conversion of the Notes; and

(C) thereafter, shares of Common Stock issued upon conversion of the Notes will be assigned an unrestricted CUSIP number and will not bear the Restricted Stock Legend (except as provided in Section 2.07(b)(iii)) or any similar legend.

(iv) Promptly after the Resale Restriction Termination Date, the Company will provide Bloomberg LLP with a copy of the Free Transferability Certificate and will use reasonable efforts to cause Bloomberg LLP to adjust its screen page for the Notes to indicate that the Notes are no longer Restricted Notes and are then identified by an unrestricted CUSIP number.

(v) Prior to the Company’s delivery of the Free Transferability Certificate and afterwards, the Company and the Trustee will comply with the Applicable Procedures and the Company shall otherwise use reasonable efforts to cause each Global Note that is not required to bear the Restricted Notes Legend to be identified by an unrestricted CUSIP number in the facilities of the Depositary by the date the Free Transferability Certificate is delivered to the Trustee and the Registrar or as promptly as possible thereafter.

Execution Version

(vi) Notwithstanding anything to the contrary in Sections 2.08(b)(i), (ii) or (iii), the Company will not be required to deliver the Free Transferability Certificate if it reasonably believes that removal of the Restricted Notes Legend or the changes to the CUSIP numbers for the Notes could result in or facilitate transfers of the Notes in violation of applicable law.

Section 2.09 Mutilated, Destroyed, Lost and Stolen Notes.

If any mutilated Note is surrendered to the Trustee, the Company shall execute, and the Trustee shall, upon receipt of a Company Order, authenticate and deliver, in exchange therefor a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of written notice to the Company or the Trustee that such Note has been acquired by a protected purchaser, the Company shall execute, and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Note has become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section 2.09, the Company may require payment by the Holder 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 Note issued pursuant to this Section 2.09 in lieu of any destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section 2.09 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 Notes.

Section 2.10 Persons Deemed Owners.

Subject to the rights of Holders as of the Regular Record Date to receive payments of interest on the related Interest Payment Date, prior to due presentment of a Note for registration of transfer, the Company, the Trustee, each Agent, and any of their respective agents may treat the Person in whose name such Note is registered in the Register as the owner of such Note for the purpose of receiving payment of the principal of such Note and for all other purposes whatsoever, whether or not such Note be overdue, and neither the Company, the Trustee, the Agents nor any of their respective agents shall be affected by notice to the contrary.

(iv) Unless the Company specifies otherwise, none of the Company, the Trustee, the Registrar or any co-Registrar will be required to exchange or register a transfer of any Note (A) that has been surrendered for conversion or (B) as to which a Fundamental Change Purchase Notice has been delivered and not withdrawn, except to the extent any portion of such Note is not subject to the foregoing.

(v) Neither the Trustee nor any Agent will have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Execution Version

(A) the Depositary is unwilling or unable to continue to act as Depositary; or

(B) the Depositary is no longer registered as a clearing agency under the Exchange Act or is otherwise no longer permitted under applicable law to continue as Depositary for such Global Note;

and, in each case, the Company promptly delivers a copy of such notice to the Trustee and the Company fails to appoint a successor Depositary within 90 days after receiving notice from the Depositary.

In each such case, the Company will, in accordance with Section 2.04, promptly execute, and, upon receipt of a Company Order, the Trustee will, in accordance with Section 2.04, promptly authenticate and deliver, for each beneficial interest in each Global Note so exchanged, an aggregate principal amount of Physical Notes equal to the aggregate principal amount of such beneficial interest, registered in such names and in such authorized denominations as the Depositary specifies, and bearing any legends that such Physical Notes are required to bear under Section 2.07.

(ii) In addition, if an Event of Default has occurred with regard to the Notes represented by the relevant Global Note and such Event of Default has not been cured or waived, any owner of a beneficial interest in a Global Note may deliver a written request through the Depositary to exchange such beneficial interest for Physical Notes.

The Company will cause any Notes so purchased (other than Notes purchased pursuant to cash-settled swaps or other cash-settled derivatives) to be surrendered to the Trustee for cancellation. For the avoidance of doubt, any such Notes purchased by the Company will be retired and no longer Outstanding hereunder.

Execution Version

The Company shall deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder that the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes previously authenticated hereunder which the Company has not issued and sold. The Trustee shall promptly cancel all Notes surrendered for registration of transfer, exchange, payment, purchase, repurchase, conversion or cancellation in accordance with its customary procedures and the Applicable Procedures (if applicable). If the Company shall acquire any of the Notes in any manner whatsoever, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. The Notes so acquired, while held by or on behalf of the Company or any of its Subsidiaries, shall not entitle the Holder thereof to convert the Notes. The Company may not issue new Notes to replace Notes it has paid in full or delivered to the Trustee for cancellation.

The Registrar shall retain, in accordance with its customary procedures, copies of all letters, notices and other written communications received pursuant to this Section 2.10. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

Section 2.13 CUSIP Numbers.

In issuing the Notes, the Company may use “CUSIP” numbers (if then generally in use); provided that the Trustee shall have no liability for any defect in the CUSIP numbers as they appear on any Notes, notice, or elsewhere. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

Section 2.14 Payment and Computation of Interest.

The Notes will bear interest (i) with respect to any interest period for which interest is paid in cash at a rate of 7.00% per year and (ii) with respect to any interest period for which interest is paid in PIK Interest at a rate of 8.00% per year, in each case until the Maturity Date, unless earlier purchased or converted in accordance with the provisions herein. Interest on the Notes will accrue from the most recent date on which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, the date of original issuance of such Notes. Interest will be paid to the Person in whose name a Note is registered at the Close of Business on the Regular Record Date immediately preceding the relevant Interest Payment Date semiannually in arrears on each Interest Payment Date; provided that, if any Interest Payment Date, Maturity Date or Fundamental Change Purchase Date of a Note falls on a day that is not a Business Day, the required payment will be made on the next succeeding Business Day and no interest on such payment will accrue in respect of the delay. Interest on the Notes shall be computed on the basis of a 360-day year consisting of twelve 30-day months; provided, however, that for any period in which a particular interest rate is applicable for less than a full semiannual period, interest on the Notes will be computed on the basis of a 30-day month and, for periods of less than a month, the actual number of days elapsed over a 30-day month.

Unless the context otherwise requires, payments of the Fundamental Change Purchase Price, principal and interest on any Note, in each case, that are not made when due will accrue interest per annum at the then-applicable interest rate from the required payment date.

The Company will pay Additional Interest under certain circumstances as provided in Section 5.08 and 6.03.

Execution Version

Section 2.15 PIK Interest.

For any interest period the Company may elect to pay all interest in kind (“PIK Interest”) on the then outstanding principal amount of the Notes (a “PIK Payment”) by (a) in the case of interest on any Global Note, increasing the principal amount of such Global Note, rounded up to the nearest whole dollar and (b) with respect to a Physical Note, issuing to the Holder of such Physical Note an additional Physical Note, the principal amount of which shall be rounded up to the nearest whole dollar (a “PIK Interest Note”).

The Company shall be deemed to have elected to pay all interest on the Notes with PIK Interest unless (i) the Company elects to pay all such interest in cash (“Cash Interest”) as described below or (ii) with respect to the final interest payment at the Maturity Date, which payment shall be Cash Interest. In the event that the Company shall elect to pay Cash Interest for any interest period, then the Company shall deliver a notice to the Trustee and the Holders not less than five Business Days prior to the applicable record date for the relevant Interest Payment Date of the relevant interest period. Notwithstanding anything to the contrary, the payment of accrued interest in connection with any repurchase of the Notes as described under Article 3 hereof will be made solely in cash.

Unless otherwise agreed between the Company and the Trustee, with respect to the payment of any PIK Interest, the Company shall deliver to the Trustee no later than two Business Days prior to the applicable Interest Payment Date, (a) with respect to Physical Notes, the required amount of new Physical Notes (rounded up to the nearest whole dollar) and a Company Order for authentication and delivery of such PIK Interest Notes on the relevant Interest Payment Date, and the Trustee in accordance with such Company order shall authenticate the PIK Interest Notes, or (b) with respect to Global Notes, unless prohibited by the procedures of the Depositary, a Company Order to increase the principal amount of the outstanding Global Note as of the Regular Record Date for the applicable Interest Payment Date, by an amount equal to the amount of interest payable for the applicable interest period (rounded up to the nearest whole dollar), and an adjustment shall be made on the books and records of the Custodian to reflect such increase. Notwithstanding anything to the contrary, the Company shall not be required to deliver to the Trustee an Officer’s Certificate or Opinion of Counsel in connection with the issuance of any PIK Interest Notes or any increase in principal amount of a Global Note as a result of any PIK Payment.

Any PIK Interest Note shall, after being executed and authenticated pursuant to Section 2.04 hereof, be mailed to the Person entitled thereto as shown on the register for the Physical Notes as of the relevant Regular Record Date. The Company will make PIK Payments on Global Notes held by the Depositary or its nominee, to the Depositary or its nominee, as the case may be, as the registered holder of such Global Note.

Any PIK Payment shall be considered paid on the date it is due (a) if PIK Interest Notes have been issued therefor, such PIK Interest Notes have been executed by the Company and authenticated by the Trustee on or prior to the date the payment is due in accordance with the terms of this Indenture and (b) if the PIK Payment is made by increasing the principal amount of Global Notes then authenticated, the Company has delivered the Company Order required by this Section 2.15 and the Trustee has increased the principal amount of Global Notes then authenticated by the relevant amount on or prior to the date the payment is due.

Execution Version

Article 3
REPURCHASE AT THE OPTION OF THE HOLDERS

Section 3.01 Purchase at Option of Holders upon a Fundamental Change.

If a Fundamental Change occurs, then each Holder shall have the right, at such Holder’s option, to require the Company to purchase for cash all of such Holder’s Notes, or any portion of such Holder’s Notes that is equal to $1,000, or an integral multiple of $1,000 (or $1.00, or an integral multiple of $1.00, following any PIK Payment on such Note or with respect to a PIK Interest Note), on a date (the “Fundamental Change Purchase Date”) specified by the Company that is not less than 20 or more than 35 Business Days after the occurrence of such Fundamental Change, at a purchase price equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest to but excluding the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”); provided, however, that if the Fundamental Change Purchase Date is after a Regular Record Date and on or prior to the Interest Payment Date to which it relates, the Company shall instead pay interest accrued to the Interest Payment Date to the Holder of record of the Note as of the preceding Regular Record Date and the Fundamental Change Purchase Price shall then be equal to 100% of the principal amount of the Note subject to purchase and will not include any accrued and unpaid interest. Notwithstanding the foregoing, there shall be no purchase of any Notes pursuant to this Section 3.01 if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes). In the event the principal amount of the Notes is accelerated following delivery of a Fundamental Change Company Notice (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes), the Trustee will promptly (i) return to the respective Holders thereof any Physical Notes tendered to it or (ii) effect appropriate book-entry transfers to the respective beneficial holders thereof any beneficial interests in a Global Note tendered to it in compliance with the Applicable Procedures, in which case, upon such return or transfer, as the case may be, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn.

Section 3.02 Fundamental Change Company Notice.

(a) General. On or before the 5th Business Day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of the Notes, the Trustee and the Paying Agent (in the case of any Paying Agent other than the Trustee) a written notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and of the purchase right at the option of the Holders arising as a result thereof. Such notice shall be sent to the Holders in accordance with Section 13.08(c) (with a copy to the Trustee). Simultaneously with providing such Fundamental Change Company Notice, the Company shall issue a press release announcing the occurrence of such Fundamental Change and make the press release available on the Company’s website. Each Fundamental Change Company Notice shall specify:

(i) the events causing the Fundamental Change;

(ii) the Effective Date of the Fundamental Change;

(iii) information about the Holder’s right to convert the Notes;

(iv) information about the Holder’s right to require the Company to purchase the Notes;

(v) the last date on which a Holder of Notes may exercise the purchase right pursuant to Section 3.01;

(vi) the Fundamental Change Purchase Price;

(xi) the procedures required for exercise of the purchase option upon the Fundamental Change, including that the Holder must exercise the purchase option prior to the Fundamental Change Expiration Time; and

(xii) that the Holder shall have the right to withdraw any Notes surrendered for purchase prior to the Fundamental Change Expiration Time and the procedures required for withdrawal of any such exercise as described in 3.05;

(c) At the Company’s written request, the Trustee shall give the Fundamental Change Company Notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the Fundamental Change Company Notice shall be prepared by the Company; provided, further that the Company shall have delivered to the Trustee, at least three Business Days before the Fundamental Change Company Notice is required to be given to the Holders (or such shorter period agreed to by the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and attaching the form of Fundamental Change Company Notice and including the information required by Section 3.02(a). Neither the Trustee nor the Paying Agent shall be responsible for determining if a Fundamental Change has occurred or for delivering a Fundamental Change Company Notice to Holders or for the content of any Fundamental Change Company Notice.

Section 3.03 Repurchase Procedures.

(a) Purchases of Notes under Section 3.01 shall be made, at the option of the Holder thereof, upon:

(i) if the Notes to be purchased are Physical Notes, delivery to the Trustee by the Holder of a duly completed notice in the Form of Fundamental Change Purchase Notice (the “Fundamental Change Purchase Notice”) together with the Physical Notes duly endorsed for transfer, at any time prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Purchase Date, (the “Fundamental Change Expiration Time”); and

(ii) if the Notes to be purchased are Global Notes, delivery to the Trustee of the beneficial interest in such Global Notes, by book-entry transfer, in compliance with the Applicable Procedures and the satisfaction of any other requirements of the Depositary in connection with tendering beneficial interests in a Global Note for purchase by the Fundamental Change Expiration Time.

Upon receipt by the Paying Agent of Physical Notes and a Fundamental Change Purchase Notice or beneficial interests in a Global Note by book-entry transfer as specified in Section 3.03, the Holder of the tendered Note shall (unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.05) thereafter be entitled to receive solely the Fundamental Change Purchase Price, in cash with respect to such Note (and any previously accrued and unpaid interest on such Note, if applicable). Such Fundamental Change Purchase Price shall be paid to such Holder, provided that the conditions in this Article 3 have been satisfied (including, without limitation, the proper delivery or book-entry transfer of such Note as required under Section 3.03(a)) and subject to the Paying Agent holding money sufficient to pay the Fundamental Change Purchase Price, promptly following the later of the applicable Fundamental Change Purchase Date and the time of delivery or book-entry transfer of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.03(a).

Section 3.05 Withdrawal of Fundamental Change Purchase Notice.

A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company Notice, as applicable, at any time prior to the Fundamental Change Expiration Time, as applicable, specifying:

(a) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted;

(b) if certificated, the certificate numbers of the withdrawn Notes; and

(c) the principal amount, if any, of each Note that remains subject to the Fundamental Change Purchase Notice, which must be such that the principal amount of such Holder’s Notes not purchased equals $1,000 or an integral multiple of $1,000;

provided, however, that if the Notes are Global Notes, the notice must comply with the Applicable Procedures.

Execution Version

The Paying Agent will promptly return to the respective Holders thereof any Physical Notes with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with the provisions of Sections 3.05 or 3.07, as applicable.

Section 3.06 Deposit of Fundamental Change Purchase Price.

Prior to 11:00 a.m., New York City time, on the Fundamental Change Purchase Date, the Company shall deposit 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 herein) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price of all the Notes or portions thereof that are to be purchased as of the Fundamental Change Purchase Date. If the Paying Agent holds money sufficient to pay the Fundamental Change Purchase Price of the tendered Notes on the Fundamental Change Purchase Date, then (a) such tendered Notes will cease to be Outstanding and (except as provided below in clause (b)) interest will cease to accrue thereon (whether or not book-entry transfer of the Notes is made or whether or not the Notes are delivered to the Paying Agent) and (b) all other rights of the Holders of such tendered Notes will terminate (other than (x) the right to receive the Fundamental Change Purchase Price and (y) the right of the Holder of record on such Regular Record Date to receive any interest payment pursuant to Section 3.01, if applicable).

Section 3.07 Notes Purchased in Whole or in Part.

Any Note that is to be purchased pursuant to this Article 3, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and, to the extent that only a part of the Note so surrendered is to be purchased, the Company shall execute and, upon receipt of a Company Order, the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased.

Section 3.08 Covenant To Comply with Applicable Laws upon Purchase of Notes.

In connection with any purchase of Notes under Section 3.01, the Company shall, in each case if required by law, (i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act to the extent any such rules are applicable, (ii) file a Schedule TO or any successor or similar schedule, if required, under the Exchange Act and (iii) otherwise comply with all U.S. federal or state securities laws applicable to the Company in connection with offer by the Company to purchase Notes under Section 3.01, in each case, so as to permit the rights and obligations under this Article 3 to be exercised in the time and in the manner specified under this Article 3.

Section 3.09 Repayment to the Company.

To the extent that the aggregate amount of money deposited by the Company pursuant to Section 3.06 exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof that the Company is obligated to purchase as of the Fundamental Change Purchase Date, then, following the Fundamental Change Purchase Date, the Paying Agent shall, upon demand of the Company, promptly return any such excess to the Company.

Article 4

CONVERSION

Section 4.01 Right to Convert.

(a) Subject to and upon compliance with the provisions of this Indenture, each Holder shall have the right, at such Holder’s option, to convert all or any portion of its Notes (if a portion, such that the principal amount of such Notes converted equals $1,000 or an integral multiple of $1,000 (or $1.00 or an integral multiple of $1.00 following any PIK Payment or with respect to a PIK Interest Note)) at an initial Conversion Rate of 1,388.889 shares of Common Stock per $1,000 aggregate principal amount of Notes into the Settlement Amount determined in accordance with Section 4.03(a)(ii) at any time until the Close of Business on the Business Day immediately preceding the stated Maturity Date; provided that the portion of the principal amount of a Holder’s Notes to be converted must be such that the principal amount not converted equals $1,000 or an integral multiple of $1,000.

(b) (i) If the Company elects to issue or distribute, as the case may be, to all or substantially all holders of the Common Stock (x) any rights, options or warrants entitling them to subscribe for or purchase, for a period expiring within 45 calendar days after the declaration date for such issuance, shares of the Common Stock, at a price per share that is less than the average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading-Day period ending on, and including, the Trading Day immediately preceding the declaration date for such issuance; or (y) cash, debt securities (or other evidence of indebtedness) or other assets or securities (excluding dividends or distributions in respect of which an adjustment to the Conversion Rate is made pursuant to Section 4.04(a)), which distribution has a per share value exceeding 10% of the Closing Sale Price of the Common Stock as of the Trading Day immediately preceding the declaration date for such distribution, then, in either case, the Company must deliver notice of such distribution, and of the Ex-Dividend Date for such distribution, to the Holders at least 30 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution.

(ii) If a transaction or event that constitutes a Fundamental Change occurs, to the extent practicable, the Company shall give notice to Holders of the anticipated effective date for such transaction or event not more than 50 Scheduled Trading Days nor less than 30 Scheduled Trading Days prior to the anticipated effective date or, if the Company does not have knowledge of such transaction or event at least 30 Scheduled Trading Days prior to the anticipated effective date, within two Business Days of the date upon which the Company receives notice, or otherwise becomes aware of such transaction or event (but in no event later than the actual effective date of such transaction or event). Neither the Trustee nor the Conversion Agent shall have any obligation (x) to determine whether the condition described in this Section 4.01(b)(ii) has occurred or (y) to verify the Company’s determination regarding such condition.

(iii) If the Company is a party to a consolidation, merger or binding share exchange or a sale, assignment, conveyance, transfer, lease or other disposition of all or substantially all of the Company’s property and assets that does not also constitute a Fundamental Change, in each case pursuant to which the Common Stock would be converted into cash, securities or other property, the Company shall notify Holders at least 30 Scheduled Trading Days prior to the anticipated effective date of such transaction. Neither the Trustee nor the Conversion Agent shall have any obligation (x) to determine whether the condition described in this Section 4.01(b)(iii) has occurred or (y) to verify the Company’s determination regarding such condition.

Execution Version

(c) Notwithstanding anything herein to the contrary, the Company shall not effect any conversion of a Note to Common Stock (including in connection with the Mandatory Conversion), and a Holder shall not have the right to convert any portion of any Note to Common Stock, to the extent that, after giving effect to such conversion, such Holder, any person having beneficial ownership of shares of Common Stock owned by the Holder, or such Holder together with such Holder’s Affiliates, and any Persons acting as a group together with such Holder or any of such Holder’s Affiliates (any such person other than Holder, including any group of which Holder is a member, an “Additional Restricted Ownership Person”), would beneficially own in excess of the Restricted Ownership Percentage (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and any Additional Restricted Ownership Person shall include the number of shares of Common Stock issuable upon conversion of the principal amount of Notes with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining, unconverted principal amount of Notes beneficially owned by such Holder or any Additional Restricted Ownership Person and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Holder or any Additional Restricted Ownership Person. Except as set forth in the preceding sentence, for purposes of this Section 4.01(c), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained in this Section 4.01(c) applies, the determination of whether the Notes are convertible (in relation to other securities owned by such Holder together with any Additional Restricted Ownership Person) and of how much principal amount of Notes are convertible shall be in the sole discretion of such Holder, and the submission of a Conversion Notice shall be deemed to be such Holder’s determination of whether the applicable Notes may be converted (in relation to other securities owned by such Holder together with any Additional Restricted Ownership Person) and how much principal amount of Notes are convertible, in each case subject to the Restricted Ownership Percentage. To ensure compliance with this restriction, each Holder will be deemed to represent to the Company each time it delivers a Conversion Notice that such Conversion Notice has not violated the restrictions set forth in this paragraph and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 4.01(c), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by the Company or (iii) a more recent written notice by the Company or the transfer agent for the Company’s Common Stock setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Notes, by such Holder or its Additional Restricted Ownership Persons since the date as of which such number of outstanding shares of Common Stock was reported. The “Restricted Ownership Percentage” for each Holder shall initially be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon conversion of Notes held by the applicable Holder. A Holder may (i) increase the Restricted Ownership Percentage applicable to its Notes upon not less than 61 days’ prior written notice to the Company, or (ii) decrease the Restricted Ownership Percentage applicable to its Notes effective immediately upon written notice to the Company; provided, however, that (x) no Holder shall be entitled to effect any increase in the Restricted Ownership Percentage applicable to its Notes if such Holder or any Additional Restricted Ownership Person has acquired beneficial ownership of Notes or any other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein with the purpose or effect of changing or influencing the control of the Company and (y) unless the Nasdaq Change of Control Approval has been obtained, the Restricted Ownership Percentage shall in no event exceed 19.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon conversion of Notes held by the applicable Holder (the “Nasdaq Change of Control Cap”). Any such increase will not be effective until the 61st day after such notice is delivered to the Company and any such increase or decrease shall only apply to such Holder and no other Holder. The Company shall use commercially reasonable best efforts to obtain at its next annual or special meeting of its stockholders following the date of this Indenture such approval of its stockholders as is necessary under the rules or regulations of the Exchange to permit each Holder and/or Additional Restricted Ownership Person to beneficially own shares of Common Stock without being subject to the Nasdaq Change of Control Cap (the “Nasdaq Change of Control Approval”). In the event that, at any time after May 1, 2020, the Company has failed to obtain the Nasdaq Change of Control Approval and any Holder elects to convert any Notes but is unable to receive shares of Common Stock upon such conversion as a result of the Nasdaq Change of Control Cap, then, notwithstanding anything in this Indenture to the contrary, Cash Settlement shall be deemed to apply with respect to any such converted Notes.

Execution Version

(d) The Company, in its discretion, may elect to cause all the Notes to mandatorily convert at the then applicable Conversion Rate (such conversion, the “Mandatory Conversion”) on a Business Day selected by the Company at any time from and after Open of Business on January 1, 2022 until the Close of Business on the Business Day immediately preceding the stated Maturity Date (the “Mandatory Conversion Date”), provided that, as of the Mandatory Conversion Date the Mandatory Conversion Price Condition has been satisfied. Upon such a Mandatory Conversion, the Company and the Trustee shall follow the following procedures in addition to the other procedures set forth in this Article 4 to the extent applicable:

(i) Notice of the Mandatory Conversion (the “Mandatory Conversion Notice”) shall be given by the Company in the manner provided for in Section 13.08(c) at least 70 but not more than 100 days prior to the Mandatory Conversion Date. All notices of conversion shall be prepared by the Company and shall state:

(A) the Mandatory Conversion Date,

(B) the aggregate principal amount of the Notes Outstanding and the amount of accrued interest to the Mandatory Conversion Date, if any,

(C) that on the Mandatory Conversion Date, all Notes Outstanding will convert into shares of the Company’s Common Stock, and, unless the Company defaults in such conversion, that interest on Notes called for conversion will cease to accrue on and after said date,

(D) the place or places where such Notes are to be surrendered for conversion,

(E) the name and address of the Paying Agent, if any,

(F) that Notes called for conversion must be surrendered to the Paying Agent to receive the shares of the Company’s Common Stock,

(G) the CUSIP number, and that no representation is made as to the accuracy or completeness of the CUSIP number, if any, listed in such notice or printed on the Notes.

At the Company’s written request, the Trustee will give the notice of conversion in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least three Business Days prior to the date notice is required to be given to Holders, an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

(ii) On and after the Mandatory Conversion Date, the conversion of all Holders’ Notes, as set forth in the Mandatory Conversion Notice, shall become irrevocable.

(iii) Notes shall be deemed to have been converted immediately upon the opening of business on the Mandatory Conversion Date, and at such time the rights of the Holders of such Notes as Holders will cease, and the Person or Persons entitled to receive the shares of Common Stock payable and issuable upon conversion will be treated for all purposes as the payee or payees of such payment and the record holder or holders of such Common Stock at such time.

Execution Version

Section 4.02 Conversion Procedures.

(a) Each Physical Note shall be convertible at the office of the Conversion Agent and, if applicable, in accordance with the Applicable Procedures.

(b) To exercise the conversion privilege with respect to a beneficial interest in a Global Note, the Holder must comply with the Applicable Procedures for converting, and effecting a book-entry transfer to the Conversion Agent of, a beneficial interest on a Global Note and pay any taxes or duties if required pursuant to Section 4.02(f), and the Conversion Agent must be informed of the conversion in accordance with the customary practice of the Depositary.

To exercise the conversion privilege with respect to any Physical Notes, the Holder of such Physical Notes shall:

(i) duly sign and complete a conversion notice in the form set forth in the Form of Notice of Conversion (the “Conversion Notice”) or a facsimile of the Conversion Notice;

(ii) deliver the Conversion Notice, which is irrevocable, and the Note to the Conversion Agent;

(iii) if required, furnish appropriate endorsements and transfer documents; and

(iv) if required, pay all transfer or similar taxes as set forth in Section 4.02(f).

If, upon conversion of a Note, any shares of Common Stock are to be issued to a Person other than the Holder of such Note, the related Conversion Notice shall include such other Person’s name and address.

If a Note has been submitted for repurchase pursuant to a Fundamental Change Purchase Notice, such Note may not be converted except to the extent such Note has been withdrawn by the Holder and is no longer submitted for repurchase pursuant to a Fundamental Change Purchase Notice or unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.07 prior to the relevant Fundamental Change Expiration Time.

For any Note, the date on which the Holder of such Note satisfies all of the applicable requirements set forth above with respect to such Note shall be the “Conversion Date” with respect to such Note.

Each conversion shall be deemed to have been effected as to any such Notes (or portion thereof) surrendered for conversion immediately prior to the Close of Business on the applicable Conversion Date; provided, however, that except to the extent required by Section 4.04, the person in whose name any shares of Common Stock shall be issuable upon conversion, if any, shall be treated as a stockholder of record (i) as of the Close of Business on the last VWAP Trading Day of the applicable Conversion Period in a Combination Settlement and (ii) as of the Close of Business on the Conversion Date in a Physical Settlement. For the avoidance of doubt, subject to the satisfaction by the Company of each of its obligations in connection with such conversion and any other conditions set forth in this Indenture, at the Close of Business on the Conversion Date for such conversion, the applicable Holder shall no longer be the Holder of the Notes so converted.

(c) Endorsement. Any Notes surrendered for conversion shall, unless shares of Common Stock issuable on conversion are to be issued in the same name as the registration of such Notes, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or its duly authorized attorney.

Execution Version

(d) Physical Notes. If any Physical Notes in a denomination greater than $1,000 (or $1.00 with respect to a PIK Interest Note) shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Physical Notes so surrendered, without charge, new Physical Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Physical Notes.

(e) Global Notes. Upon the conversion of a beneficial interest in Global Notes, the Conversion Agent shall make a notation in its records as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Notes effected through any Conversion Agent other than the Trustee.

(f) Taxes Due upon Conversion. If a Note is converted, the Company will pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of the Common Stock upon the conversion, unless the tax is due because the Holder requests that any shares be issued in a name other than the Holder’s name, in which case the Holder will pay that tax.

Section 4.03 Settlement Upon Conversion.

(a) Settlement. Subject to this Section 4.03 and Sections 4.06 and 4.07, if the Company has received the Stockholders Approval prior to the relevant Settlement Method Election Date, upon conversion of any Note, the Company shall pay or deliver, as the case may be, to Holders, in full satisfaction of its conversion obligation under Section 4.01, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount consisting of, at the election of the Company in accordance with the requirements specified herein, solely cash (“Cash Settlement”), solely shares of Common Stock (together with cash in lieu of any fractional share of Common Stock pursuant to Section 4.03(b)) (“Physical Settlement”) or a combination of cash and shares of Common Stock (“Combination Settlement”).

(i) Settlement Election. If the Company has received the Stockholders Approval prior to the relevant Settlement Method Election Date, all conversions occurring on or after the 25th Scheduled Trading Day immediately preceding the Maturity Date shall be settled by the same Settlement Method. Prior to the 25th Scheduled Trading Day immediately preceding the Maturity Date, the Company will use the same Settlement Method for all conversions occurring on the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions that occur on different Conversion Dates, subject to the limitation set forth Section 4.03(a)(ii) if the Company has not received the Stockholders Approval prior to the relevant Settlement Method Election Date. If the Company elects a Settlement Method (a “Settlement Election”) and a Specified Dollar Amount, if applicable (a “Specified Dollar Amount Election”), the Company shall provide to the Holders of Notes so converting through the Trustee a notice of such Settlement Method (each such notice, a “Settlement Election Notice”) or such Specified Dollar Amount (each such notice, a “Specified Dollar Amount Election Notice”), (x) no later than the Close of Business on the Business Day immediately following the related Conversion Date or (y) in the case of any conversions occurring on or after the 25th Scheduled Trading Day immediately preceding the Maturity Date, no later than the Close of Business on the Business Day immediately prior to the 25th Scheduled Trading Day immediately preceding the Maturity Date (the “Settlement Method Election Date”). In the event that the Company has received the Stockholders Approval prior to the relevant Settlement Method Election Date, if the Company does not elect a Settlement Method on or prior to the relevant Settlement Method Election Date, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement, and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes converted shall be deemed to be $1,000. If the Company has received the Stockholders Approval prior to the relevant Settlement Method Election Date, and the Company elects Combination Settlement but does not notify Holders of Notes so converting of the Specified Dollar Amount per $1,000 principal amount of Notes on or prior to the relevant Settlement Method Election Date, such Specified Dollar Amount will be deemed to be $1,000.

Execution Version

In addition, if the Company has received the Stockholders Approval prior to the relevant Settlement Election Date, the Company may, at its option, irrevocably elect Combination Settlement with a particular Specified Dollar Amount for all conversions with a Conversion Date subsequent to its notice to Holders thereof by notice of such election to Holders, the Trustee and the Conversion Agent.

(ii) Notwithstanding anything to the contrary in the Notes or this Indenture, the Company shall not be permitted to elect Physical Settlement or Combination Settlement with respect to any conversion of Notes and Cash Settlement shall be deemed to apply to such conversion unless prior to the relevant Settlement Method Election Date the Company has received the Stockholders Approval; provided that with respect to any Conversion Date occurring prior to the 25th Scheduled Trading Day immediately preceding the Maturity Date, the Company may, regardless of whether the Stockholders Approval has been obtained, elect Physical Settlement or a Combination Settlement for all Notes converted on such Conversion Date if, and only if:

(A) the aggregate number of shares of Common Stock deliverable upon conversion of such Notes as if Physical Settlement applied to all such Notes is less than:

(1) the Aggregate Available Share Cap; minus

(2) the aggregate number of shares of Common Stock delivered or deliverable, in each case, upon previous conversions of Notes; and

(B) the Company informs converting Holders, the Conversion Agent and the Trustee that the Company has elected Physical Settlement or a Combination Settlement for such Notes no later than the Close of Business on the second VWAP Trading Day immediately following the Conversion Date for such Notes.

The Company shall promptly notify Holders, the Trustee and the Conversion Agent by press release upon obtaining the Stockholders Approval.

(iii) Settlement Amount. The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows:

(A) if the Company elects Physical Settlement, the Company shall deliver to the Holder of the Notes so converting, in respect of each $1,000 principal amount of its Notes being converted, a number of shares of Common Stock equal to the applicable Conversion Rate, together with cash in lieu of any fractional shares of Common Stock pursuant to Section 4.03(b);

(B) if the Company elects Cash Settlement, the Company shall pay to the Holder of the Notes so converting, in respect of each $1,000 principal amount of its Notes being converted, cash in an amount equal to the sum of the Daily Conversion Values for each of the 20 consecutive VWAP Trading Days during the related Conversion Period; and

(C) if the Company elects (or is deemed to have elected) Combination Settlement, the Company shall pay or deliver, as the case may be, to the Holder of the Notes so converting, in respect of each $1,000 principal amount of its Notes being converted, an amount of cash and number of shares of Common Stock, if any, equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive VWAP Trading Days during the related Conversion Period.

(iv) Delivery Obligation. The Settlement Amounts upon conversion of the Notes will be paid or delivered, as the case may be, by the Company through the Conversion Agent. The Company shall pay or deliver, as the case may be, the Settlement Amount due in respect of its conversion obligation under this Section 4.03, (i) on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement and (ii) on the third Business Day immediately following the last VWAP Trading Day of the related Conversion Period, in any other case; provided, however, that if prior to the Conversion Date for any converted Notes, the Common Stock has been replaced by Reference Property consisting solely of cash, the Company will pay the conversion consideration due in respect of such conversion on the third Trading Day immediately following the related Conversion Date, and, notwithstanding the foregoing in this Section 4.03, no Conversion Period will apply to those conversions. For the avoidance of doubt, in the case of Cash Settlement or Combination Settlement, if a VWAP Market Disruption Event occurs on a Scheduled Trading Day during the Conversion Period, or if such Scheduled Trading day is not a VWAP Trading Day for any other reason, then the Daily Conversion Value or Daily Settlement Amount, as applicable, will be determined on the next following VWAP Trading Day, and delivery of the Settlement Amount will be delayed accordingly. No interest will accrue on account of such delay.

(b) Fractional Shares. Notwithstanding the foregoing, the Company will not issue fractional shares of Common Stock as part of the Settlement Amount due with respect to any converted Note. Instead, if any Settlement Amount includes a fraction of a share of the Common Stock, the Company will, in lieu of delivering such fraction of a share of Common Stock, pay an amount of cash equal to the product of such fraction of a share and (i) in a Physical Settlement, the Daily VWAP on the relevant Conversion Date, or if such Conversion Date is not a VWAP Trading Day, the immediately preceding VWAP Trading Day or (ii) in the case of any other Settlement Method, the Daily VWAP on the last VWAP Trading Day of the relevant Conversion Period.

(c) Conversion of Multiple Notes by a Single Holder. If a Holder surrenders more than one Note for conversion on a single Conversion Date, the Company will calculate the amount of cash and the number of shares of Common Stock due with respect to such Notes as if such Holder had surrendered for conversion one Note having an aggregate principal amount equal to the sum of the principal amounts of each of the Notes surrendered for conversion by such Holder on such Conversion Date or, if the Notes surrendered for conversion are beneficial interests in a Global Note, based on such other aggregate number of Notes, or beneficial interests therein, being surrendered by the Holder for conversion on the same date as the Depositary may otherwise request.

(d) Settlement of Accrued Interest and Deemed Payment of Principal. If a Note is converted, the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note, and the Company’s delivery or payment, as the case may be, of cash, shares of Common Stock or a combination of cash and shares of Common Stock into which a Note is convertible will be deemed to satisfy and discharge in full the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Note to, but excluding, the Conversion Date; provided, however, that if a Note is converted after the Close of Business on a Regular Record Date and prior to the Open of Business on the corresponding Interest Payment Date, the Company will still be obligated to pay the interest due on such Interest Payment Date to the Holder of such Note on such Regular Record Date.

As a result, except as otherwise provided in the proviso to the immediately preceding sentence, any accrued and unpaid interest with respect to a converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In addition, if the Settlement Amount for any Note includes both cash and shares of Common Stock, accrued but unpaid interest will be deemed to be paid first out of the amount of cash delivered upon such conversion.

(e) Notices. Whenever a Conversion Date occurs with respect to a Note, the Conversion Agent will, as promptly as possible, and in no event later than the Business Day immediately following such Conversion Date, deliver to the Company and the Trustee, if it is not then the Conversion Agent, written notice that a Conversion Date has occurred, which notice will state such Conversion Date, the principal amount of Notes converted on such Conversion Date and the names of the Holders that converted Notes on such Conversion Date.

On the first Business Day immediately following the last VWAP Trading Day of the Conversion Period applicable to any Note surrendered for conversion in a Cash Settlement or a Combination Settlement, the Company will deliver a written notice to the Conversion Agent and the Trustee (if not also the Conversion Agent) stating the amount of cash and the number of shares of Common Stock, if any, that the Company is obligated to pay or deliver, as the case may be, to satisfy its conversion obligation with respect to each Note converted on such Conversion Date.

Section 4.04 Adjustment of Conversion Rate.

The Conversion Rate will be adjusted as described in this Section 4.04, except that no adjustment to the Conversion Rate will be made for a given transaction if Holders of the Notes will participate in that transaction, without conversion of the Notes, on the same terms and at the same time as a holder of a number of shares of Common Stock equal to the principal amount of a Holder’s Notes divided by $1,000 and multiplied by the Conversion Rate would participate.

Execution Version

(a) If the Company issues solely shares of Common Stock as a dividend or distribution on all or substantially all shares of the Common Stock, or if the Company subdivides or combines the Common Stock, the Conversion Rate will be adjusted based on the following formula:

where,

	CR =	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date of such dividend or distribution, or immediately after the Open of Business on the effective date of such share split or combination, as applicable;
	CR₀ =	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the Open of Business on the effective date of such share split or combination, as applicable;
	OS =	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date of such dividend or distribution, or immediately prior to the Open of Business on the effective date of such share split or combination, as applicable; and
	OS₀ =	the number of shares of Common Stock outstanding immediately after giving effect to such dividend or distribution, or immediately after the effective date of such subdivision or combination of common stock, as the case may be.

Any adjustment made under this clause (a) will become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution (regardless of whether the dividend or distribution date is scheduled to occur after the Maturity Date), or immediately after the Open of Business on the effective date of such subdivision or combination of Common Stock, as the case may be. If such dividend, distribution, subdivision or combination described in this clause (a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors or a duly authorized committee thereof determines not to pay such dividend or distribution or to effect such subdivision or combination, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or subdivision or combination had not been announced.

Execution Version

(b) If an Ex-Dividend Date occurs for a distribution to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days from the announcement date for such distribution, to subscribe for or purchase shares of the Common Stock, at a price per share less than the average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading-Day period ending on, and including, the Trading Day immediately preceding the announcement date for such distribution, the Conversion Rate will be increased based on the following formula:

	where,

	CR =	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date for such distribution;
	CR₀ =	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
	OS₀ =	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date for such distribution;
	X =	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
	Y =	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading-Day period ending on, and including, the Trading Day immediately preceding the announcement date for such distribution.

Any increase made under this clause (b) will be made successively whenever any such rights, options or warrants are issued and will become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution, regardless of whether the distribution date is scheduled to occur after the Maturity Date. To the extent that such rights, options or warrants expire prior to the Maturity Date and shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants were scheduled to be distributed prior to the Maturity Date and are not so distributed, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if the Ex-Dividend Date for such distribution had not occurred.

Execution Version

For purposes of this Section 4.04(b) and Section 4.01(b)(i), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of Common Stock at a price that is less than the average of the Closing Sale Prices of the Common Stock for each Trading Day in the applicable 10 consecutive Trading-Day period, there shall be taken into account any consideration the Company receives for such rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration, if other than cash, to be determined in good faith by the Board of Directors or a duly authorized committee thereof.

(c) If an Ex-Dividend Date occurs for a distribution (the “Relevant Distribution”) of shares of the Company’s Capital Stock, evidences of the Company’s indebtedness or other assets or property of the Company’s or rights, options or warrants to acquire the Company’s Capital Stock or other securities, to all or substantially all holders of Common Stock (excluding (i) dividends or distributions and rights, options or warrants as to which an adjustment was effected under clause (a) or (b) above; (ii) dividends or distributions paid exclusively in cash; and (iii) Spin-Offs), then the Conversion Rate will be increased based on the following formula:

where,

	CR =	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date for such distribution;
	CR₀ =	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
	SP₀ =	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day-period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
	FMV =	the fair market value (as determined in good faith by the Board of Directors or a duly authorized committee thereof) of the shares of Capital Stock, evidences of indebtedness, assets or property or rights, options or warrants distributed with respect to each outstanding share of Common Stock as of the Open of Business on the Ex-Dividend Date for such distribution.

Any increase made under the above portion of this clause (c) will become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate. However, if such distribution is scheduled to be paid or made prior to the Maturity Date and is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock, without having to convert its Notes, the amount and kind of the Relevant Distribution that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution.

Execution Version

With respect to an adjustment pursuant to this clause (c) where there has been an Ex-Dividend Date for 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, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate will be increased based on the following formula:

where,

	CR =	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such Spin-Off;
	CR₀ =	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such Spin-Off;
	FMV₀ =	the average of the Closing Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock over the first 10 consecutive Trading-Day period commencing on, and including, the Ex-Dividend Date for the Spin-Off (such period, the “Valuation Period”); and
	MP₀ =	the average of the Closing Sale Prices of Common Stock over the Valuation Period.

The adjustment to the applicable conversion rate under the preceding paragraph of this clause (c) will be determined on the last day of the Valuation Period but will be given effect immediately after the Open of Business on the Ex-Dividend Date for the Spin-Off. If the Ex-Dividend Date for the Spin-Off is less than 10 Trading Days prior to, and including, the end of the Conversion Period in respect of any conversion, references within this clause (c) to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last VWAP Trading Day of such Conversion Period. In respect of any conversion during the Valuation Period for any Spin-Off, references within this clause (c) related to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, but excluding, the relevant Conversion Date.

For purposes of the second adjustment formula set forth in this Section 4.04(c), (i) the Closing Sale Price of any Capital Stock or similar equity interest shall be calculated in a manner analogous to that used to calculate the Closing Sale Price of the Common Stock in the definition of “Closing Sale Price” set forth in Section 1.01, (ii) whether a day is a Trading Day (and whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for such Capital Stock or similar equity interest shall be determined in a manner analogous to that used to determine whether a day is a Trading Day (or whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for the Common Stock, and (iii) whether a day is a Trading Day to be included in a Valuation Period will be determined based on whether a day is a Trading Day for both the Common Stock and such Capital Stock or similar equity interest.

Execution Version

Subject to Section 4.04(g), for the purposes of this Section 4.04(c), rights, options or warrants distributed to all or substantially all holders of the Common Stock entitling them to acquire the Company’s Capital Stock or other securities, (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock; (2) are not exercisable; and (3) are also issued in respect of future issuances of Common Stock (including, for the avoidance of doubt, upon settlement of conversions of Notes), shall be deemed not to have been distributed for purposes of this Section 4.04(c) (and no adjustment to the Conversion Rate under this Section 4.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or 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 4.04(c). If any such rights, options or warrants, distributed prior to the Issue Date are subject to events, upon the occurrence of which such rights, options 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 Ex-Dividend Date of such deemed distribution (in which case the original rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders). In addition, in the event of any distribution or deemed distribution of rights, options 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 4.04(c) was made, (1) in the case of any such rights, options or warrants which shall all have been redeemed or purchased without exercise by any Holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed 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 holders of Common Stock with respect to such rights, options or warrants (assuming each such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options 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.

For purposes of Sections 4.04(a) through (c), if any dividend or distribution to which this Section 4.04(c) applies includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 4.04(a) also applies (the “Clause A Distribution”); or

(B) an issuance of rights, options or warrants entitling holders of the Common Stock to subscribe for or purchase shares of the Common Stock to which Section 4.04(b) also applies (the “Clause B Distribution”),

then (i) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a distribution to which this Section 4.04(c) applies (the “Clause C Distribution”) and any Conversion Rate adjustment required to be made under this Section 4.04(c) with respect to such Clause C Distribution shall be made, (ii) the Clause B Distribution, if any, shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 4.04(b) with respect thereto shall then be made, except that, if determined by the Company, (A) the “Ex-Dividend Date” of the Clause B Distribution and the Clause A Distribution, if any, shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (B) any shares of Common Stock included in the Clause A Distribution or the Clause B Distribution shall not be deemed to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date” within the meaning of Section 4.04(b), and (iii) the Clause A Distribution, if any, shall be deemed to immediately follow the Clause C Distribution or the Clause B Distribution, as the case may be, except that, if determined by the Company, (A) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution, if any, shall be deemed to be the Ex-Dividend Date of the Clause C Distribution, and (B) any shares of Common Stock included in the Clause A Distribution shall not be deemed to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date or such effective date” within the meaning of Section 4.04(a).

Execution Version

(d) If an Ex-Dividend Date occurs for a cash dividend or distribution to all, or substantially all, holders of the outstanding Common Stock (other than any dividend or distribution in connection with the Company’s liquidation, dissolution or winding up), the Conversion Rate will be increased based on the following formula:

where,

	CR =	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;
	CR₀ =	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;
	SP₀ =	the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
	C =	the amount in cash per share that the Company pays or distributes to substantially all holders of the Common Stock.

Any increase made under this clause (d) shall become effective immediately after the Open of Business on the Ex-Dividend date for such dividend or distribution. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate. However, if any dividend or distribution described in this clause (d) is scheduled to be paid or made prior to the Maturity Date but is not so paid or made, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, without having to convert its Notes, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the applicable Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution.

Execution Version

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for the Common Stock, and if the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading-Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Offer Expiration Date”), the Conversion Rate will be increased based on the following formula:

where,

	CR =	the Conversion Rate in effect immediately after the Open of Business on the Trading Day next succeeding the Offer Expiration Date;
	CR₀ =	the Conversion Rate in effect immediately prior to the Open of Business on the Trading Day next succeeding the Offer Expiration Date;
	AC =	the aggregate value of all cash and any other consideration (as determined in good faith by the Board of Directors or a duly authorized committee thereof) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
	OS₀ =	the number of shares of Common Stock outstanding immediately prior to the time (the “Offer Expiration Time”) such tender or exchange offer expires (prior to giving effect to such tender or exchange offer);
	OS =	the number of shares of Common Stock outstanding immediately after the Offer Expiration Time (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer); and
	SP =	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading-Day period commencing on, and including, the Trading Day next succeeding the Offer Expiration Date.

The adjustment to the Conversion Rate under the preceding paragraph of this clause (e) will be determined at the Close of Business on the tenth Trading Day immediately following, but excluding, the Offer Expiration Date but will be given effect at the Open of Business on the Trading Day next succeeding the Offer Expiration Date. If the Trading Day next succeeding the Offer Expiration Date is less than 10 Trading Days prior to, and including, the end of the Conversion Period in respect of any conversion, references within this clause (e) to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to, and including, the last VWAP Trading Day of such Conversion Period. In respect of any conversion during the 10 Trading Days commencing on the Trading Day next succeeding the Offer Expiration Date, references within this clause (e) to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to, but excluding, the relevant Conversion Date. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate.

(f) Special Settlement Provisions. Notwithstanding anything to the contrary herein, if a Note is converted and:

(i) Combination Settlement is applicable to such Note and shares of Common Stock are deliverable to settle the Daily Net Share Number for a given VWAP Trading Day within the Conversion Period applicable to such Note;

Execution Version

(ii) any distribution, transaction or event described in Sections 4.04(a) through (e) has not yet resulted in an adjustment to the Conversion Rate on such VWAP Trading Day; and

(iii) the shares of Common Stock deliverable in respect of such VWAP Trading Day are not entitled to participate in the relevant distribution or transaction (because such shares of Common Stock were not held on a related Record Date or otherwise),

then the Company will adjust the number of shares of Common Stock delivered in respect of the relevant VWAP Trading Day to reflect the relevant distribution or transaction.

If a Note is converted and:

(i)

Physical Settlement is applicable to such Note;

(ii)

any distribution or transaction described in Sections 4.04(a) through (e) has not yet resulted in an adjustment to the Conversion Rate on a given Conversion Date; and

(iii)

the shares of Common Stock deliverable on settlement of the related conversion are not entitled to participate in the relevant distribution or transaction (because such shares of Common Stock were not held on a related Record Date or otherwise),

then the Company will adjust the number of shares of Common Stock delivered in respect of the relevant conversion to reflect the relevant distribution or transaction.

Notwithstanding the foregoing, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date as described above, and a Holder of Notes that has converted on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of shares of Common Stock as of the related Conversion Date pursuant to Section 4.03 based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the foregoing Conversion Rate adjustment provisions, the Conversion Rate adjustment relating to such Ex-Dividend Date will not be made for the Holder of such converting Notes. Instead, such Holder will be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(g) Poison Pill. If a Note is converted, to the extent that the Company has a rights plan in effect, if Physical Settlement applies to such Note, on the Conversion Date applicable to such Note, and if Combination Settlement applies to such Note on any VWAP Trading Day in the Conversion Period applicable to such Note, the Holder of such converting Note will receive, in addition to any shares of Common Stock otherwise received in connection with such conversion on such Conversion Date or such VWAP Trading Day, as the case may be, the rights under the rights plan, unless prior to such Conversion Date or such VWAP Trading Day, as the case may be, the rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be adjusted at the time of separation as if the Company distributed to all holders of the Common Stock, Distributed Property as described in Section 4.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

Execution Version

(h) Deferral of Adjustments. Notwithstanding anything to the contrary herein, the Company will not be required to adjust the Conversion Rate unless such adjustment would result in a change of at least one percent; provided, however, that the Company shall carry forward any adjustments that are less than one percent of the Conversion Rate and make such carried forward adjustments (i) when the cumulative net effect of all adjustments not yet made will result in a change of at least one percent of the Conversion Rate or (ii) regardless of whether the aggregate adjustment is less than one percent, (1) upon any offer to purchase the Notes following a Fundamental Change, (2) on each of the VWAP Trading Days within any Conversion Period, (3) upon any conversion of Notes and (4) on the Effective Date for any Fundamental Change.

(i) Limitation on Adjustments. Except as stated in this Section 4.04, the Company will not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities. If, however, the application of the formulas in Sections 4.04(a) through (e) would result in a decrease in the Conversion Rate, then, except to the extent of any readjustment to the Conversion Rate, no adjustment to the Conversion Rate will be made (other than as a result of a reverse share split or share combination).

For purposes of this Section 4.04, 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.

Section 4.05 Discretionary and Voluntary Adjustments.

(a) Discretionary Adjustments. Whenever any provision of this Indenture requires the Company to calculate the Closing Sale Prices, the Daily VWAPs or any function thereof over a span of multiple days (including during an Conversion Period), the Company will make appropriate adjustments to each, if any, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the effective date, Ex-Dividend Date or Offer Expiration Date of the event occurs, at any time during the period when such Closing Sale Prices, the Daily VWAPs or function thereof is to be calculated.

(b) Voluntary Adjustments. To the extent permitted by law and any applicable rules of the Exchange, the Company is permitted to increase the Conversion Rate of the Notes by any amount for a period of at least 20 Business Days if such increase is irrevocable for such period and the Board of Directors determines that such increase would be in the Company’s best interest; provided that the Company must give at least 15 days’ prior notice of any such increase in the Conversion Rate. The Company may also (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event.

Section 4.06 [RESERVED]

Execution Version

Section 4.07 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale.

(a) Merger Events. In the case of:

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a split, subdivision or combination for which an adjustment was made pursuant to Section 4.04(a));

(ii) any consolidation, merger, combination, binding share exchange or similar transaction involving the Company;

(iii) any sale, assignment, conveyance, transfer, lease or other disposition to a third party of the consolidated property and assets of the Company as an entirety or substantially as an entirety; or

(iv) a liquidation or dissolution of the Company;

and, in each case, as a result of which the Common Stock would be converted into, or exchanged for, common stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Merger Event,” any such common stock, other securities, other property or assets (including cash or any combination thereof), “Reference Property,” and (i) the amount and kind of Reference Property that a holder of one share of Common Stock is entitled to receive in the applicable Merger Event, or (ii) if as a result of the applicable Merger Event, each share of Common Stock is converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the per share of Common Stock weighted average of the amounts and kinds of Reference Property received by the holders of Common Stock that affirmatively make such an election (disregarding, for these purposes, any arrangement to deliver cash in lieu of any fractional security or other unit of Reference Property), a “Unit of Reference Property”) then, at the effective time of such Merger Event, Holders of each $1,000 principal amount of Notes shall be entitled thereafter to convert such Notes into the kind and amount of Reference Property that a Holder of a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to such Merger Event would have owned or been entitled to receive upon such Merger Event, and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing person, as the case may be, shall execute with the Trustee a supplemental indenture providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of the Merger Event, (x) the Company will continue to have the right to determine the Settlement Method upon conversion of the Notes pursuant to Sections 4.03(a)(i) and 4.03(a)(ii), as applicable, and (y) (i) any amount payable in cash upon conversion of the Notes in accordance with Section 4.03 and 4.06 shall continue to be payable in cash, (ii) the number of shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 4.03 and 4.06 shall instead be deliverable in Units of Reference Property that a Holder of that number of shares of Common Stock would have received in such Merger Event and (iii) the Daily VWAP and the Closing Sale Price will, to the extent reasonably possible, be calculated based on the value of a Unit of Reference Property and the definitions of VWAP Trading Day and VWAP Market Disruption Event shall be determined by reference to the components of a Unit of Reference Property. The Company shall notify in writing the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

Execution Version

The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 4.07. Such supplemental indenture described in the immediately preceding paragraph shall provide for adjustments which shall be as nearly equivalent to the adjustments provided for in this Article 4 in the judgment of the Board of Directors or the board of directors of the successor person. If, in the case of any such Merger Event, the Reference Property receivable thereupon by a holder of Common Stock includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a person other than the successor or purchasing person, as the case may be, in such Merger Event, then such indenture shall also be executed by such other person.

If the Notes become convertible into, or exchanged for Reference Property, the Company shall notify the Trustee and the Conversion Agent, and shall issue a press release containing the relevant information (and make such press release available on the Company’s website).

(b) Notice of Supplemental Indentures. The Company shall cause written notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Notes maintained by the Registrar, within 20 calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section 4.07 shall similarly apply to successive Merger Events.

(c) Prior Notice. In addition, at least 20 Scheduled Trading Days before any Merger Event, the Company shall give notice to Holders of such Merger Event, or, if the Company has not publicly announced such Merger Event at such time, as promptly as practicable after publicly announcing such Merger Event.

The Trustee and any other Conversion Agent (if other than the Company) shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock or of any other securities or property that may at any time be issued or delivered upon the conversion of any Notes; and the Trustee and the Conversion Agent (if other than the Company) make no representations with respect thereto. Neither the Trustee nor any Conversion Agent (if other than the Company) shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Notes for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 4. The rights, privileges, protections, immunities and benefits given to the Trustee, including without limitation its right to be compensated, reimbursed and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including its capacity as Conversion Agent.

Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent (if other than the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall (i) issue a press release and make the press release available on the Company’s website and (ii) prepare a notice of such adjustment of the Conversion Rate, in each case, setting forth the adjusted Conversion Rate and the date as of which each adjustment becomes effective and shall deliver such notice of such adjustment of the Conversion Rate to the Holder of each Note at his or her last address appearing on the Register provided for in Section 2.06 of this Indenture, within 20 days after execution thereof.

Such Additional Interest will be payable in the same manner and on the same dates as the stated interest payable on the Notes.

Payments of the Fundamental Change Purchase Price, principal and interest that are not made when due will accrue interest per annum at the then-applicable interest rate from the required payment date.

Section 6.08 Collection of Indebtedness; Suit for Enforcement by Trustee.

If an Event of Default specified in Section 6.01(a), 6.01(b), 6.01(c) or 6.01(d) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium on, interest on, Fundamental Change Purchase Price for and the Settlement Amounts due upon the conversion of the Notes and such further amount as is sufficient to cover the costs and expenses of collection, including the compensation and reasonable expenses, disbursements and advances of the Trustee, its agents and counsel, as well as any other amounts that may be due under Section 11.06.

Section 6.10 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company or any Subsidiary Guarantor, its creditors or its property and, unless prohibited by law or applicable regulations, will be entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian 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 consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the compensation and reasonable expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 11.06. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 11.06 out of the estate in any such proceeding, will be denied for any reason, payment of the same will be secured by a lien on, and is paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained will be deemed to authorize the Trustee to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.11 Restoration of Rights and Remedies.

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 6.12 Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.09, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.13 Delay or Omission Not a Waiver.

No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time and as often as may be deemed expedient by the Trustee (subject to the limitations contained in this Indenture) or by the Holders, as the case may be.

THIRD: the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs.

Section 6.17 Notices from the Trustee.

If a Default occurs and is continuing and is known to the Trustee, the Trustee must send notice of such Default to each Holder within 90 days after such Event of Default has occurred. Except in the case of a Default in the payment of the principal of, premium, if any, or interest on any Note or of a Default in the payment or delivery of the Settlement Amounts due upon conversion of any Note, the Trustee may withhold notice if and so long as the Trustee in good faith determines that withholding notice is in the interests of the Holders.

Section 9.02 Successor Corporation to Be Substituted.

In case of any such consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition to another Person and upon the assumption by the Successor Company (if other than the Company), by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and premium (including any Fundamental Change Purchase Price), if any, and accrued and unpaid interest, if any, on all of the Notes, the due and punctual payment or delivery of any Settlement Amount due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company under this Indenture, such Successor Company 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 it had been named herein as the party of the first part; provided, however, that in the case of a sale, assignment, conveyance, transfer, lease or other disposition to one or more of its Subsidiaries of all or substantially all of the properties and assets of the Company, the Notes will remain convertible based on the Settlement Amount, in accordance with Section 4.03, but subject to adjustment (if any) in accordance with Section 4.06.

Section 9.03 Officer’s Certificate and Opinion of Counsel to Be Given to Trustee.

In the case of any such consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition pursuant to Section 9.01, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel stating that any such consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Indenture and an Opinion of Counsel stating that any such supplemental indenture is the valid, binding and enforceable obligation of the Successor Company.

In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care in its exercise as a prudent person would use in the conduct of his or her own affairs.

(i) this subsection (c) does not limit the effect of this Section 11.01;

(ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless the Trustee was negligent in ascertaining the pertinent facts; and

(iii) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the written direction of the Holders of not less than a majority in principal amount of the Notes at the time Outstanding determined as provided in Section 1.03 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Indenture;

Section 11.02 Rights of the Trustee.

(a) The Trustee may conclusively rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, coupon or other paper or document (whether in its original or facsimile form) believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties.

(j) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Agent, custodian and other Person employed to act hereunder.

Section 11.03 Trustee’s Disclaimer.

The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture, the Subsidiary Guarantees or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee under this Indenture and the Trustee shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Notes.

Execution Version

Section 11.06 Compensation and Expenses of Trustee.

The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to from time to time in writing between the Company and the Trustee, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its own gross negligence or willful misconduct, as determined by a final order of a court of competent jurisdiction.

The Company also covenants to indemnify each of the Trustee and the Agents (and their respective officers, directors and employees), in any capacity under this Indenture and their respective agents for, and to hold each of them harmless from and against, any and all loss, liability, claim, damage, cost or expense incurred without gross negligence or willful misconduct, as determined by a final order of a court of competent jurisdiction on its own part and arising out of or in connection with the acceptance or administration of this trust and the performance of its duties and/or the exercise of its rights hereunder or in any other capacity hereunder, including the costs and expenses of defending itself against any claim (whether asserted by the Company, a Holder or any other Person) of liability in the premises. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent.

The obligations of the Company under this Section 11.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Notes. The obligation of the Company under this Section 11.06 shall survive the payment of the Notes, the satisfaction and discharge of this Indenture and/or the resignation or removal of the Trustee.

When the Trustee, any Agent, and any of their respective agents incur expenses or render services after an Event of Default specified in Section 6.01(i) and 6.01(j) with respect to the Company occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank holding company system, its bank holding company shall have a combined capital and surplus of at least $50,000,000). If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section 11.09 the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 11.09, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

(a) The Trustee may at any time resign by giving written notice of such resignation to the Company and to the Holders of Notes. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment thirty (30) days after such notice of resignation is given to the Company and the Holders, the resigning Trustee may, upon ten (10) Business Days’ notice to the Company and the Holders, appoint a successor identified in such notice or may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or, if any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months may, subject to the provisions of Section 6.15, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b) In case at any time any of the following shall occur:

(i) the Trustee shall fail to comply with Section 11.08 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months; or

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 11.09 and shall fail to resign after written request therefor by the Company or by any such Holder; or

(iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Company may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 6.15, any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee; provided, however, that if no successor Trustee shall have been appointed and have accepted appointment thirty (30) days after either the Company or the Holders has removed the Trustee, the Trustee so removed may petition at the Company’s expense any court of competent jurisdiction for an appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

Execution Version

(c) The Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may at any time remove the Trustee and nominate a successor trustee which shall be deemed appointed as successor trustee unless, within ten (10) days after notice to the Company of such nomination, the Company objects thereto, in which case the Trustee so removed or any Holder, or if such Trustee so removed or any Holder fails to act, the Company, upon the terms and conditions and otherwise as in Section 11.10(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 11.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 11.11.

Section 11.11 Acceptance by Successor Trustee.

Any successor trustee appointed as provided in Section 11.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of Section 11.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 11.06.

No successor trustee shall accept appointment as provided in this Section 11.11 unless, at the time of such acceptance, such successor trustee shall be qualified under the provisions of Section 11.08 and be eligible under the provisions of Section 11.09.

Upon acceptance of appointment by a successor trustee as provided in this Section 11.11, the Company (or the former trustee, at the written direction of the Company) shall give or cause to be given notice of the succession of such trustee hereunder to the Holders of Notes in accordance with Section 13.08(c). If the Company fails to give such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be given at the expense of the Company.

Section 11.12 Succession by Merger, Etc.

Any corporation into which the Trustee may be merged or exchanged or with which it may be consolidated, or any corporation resulting from any merger, exchange or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee (including any trust created by this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that in the case of any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, such corporation shall be qualified under the provisions of Section 11.08 and eligible under the provisions of Section 11.09.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or any authenticating agent appointed by such successor trustee may authenticate such Notes in the name of the successor trustee; and in all such cases such certificates shall have the full force that is provided in the Notes or in this Indenture; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, exchange or consolidation.

Section 11.13 Preferential Collection of Claims.

If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the Company (or any such other obligor).

Section 11.14 Trustee’s Application for Instructions from the Company.

Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three (3) Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

(a) Subject to this Article 12, each of the Subsidiary Guarantors, jointly and severally, fully and unconditionally, guarantees, on a senior unsecured basis, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: (i) the principal of, premium, if any, and interest on the Notes will be promptly paid in full when due, whether at the stated Maturity Date, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium, if any, and interest on the Notes, if any, if lawful (subject in all cases to any applicable grace period provided herein), and all other monetary obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that 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 or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Subsidiary Guarantors shall be jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Subsidiary Guarantors agree that, to the maximum extent permitted under applicable law, their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor. Subject to Section 6.06, each Subsidiary Guarantor waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Subsidiary Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Subsidiary Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either of the Company or the Subsidiary Guarantors, any amount paid by either to the Trustee or such Holder, this Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

(d) Each Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Subsidiary Guarantor further agrees that, as between the Subsidiary Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Nine for the purposes of this Subsidiary 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 declaration of acceleration of such obligations as provided in Article 6, such obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantors for the purpose of this Subsidiary Guarantee. Each Subsidiary Guarantor that makes a payment or distribution under its Subsidiary Guarantee shall have the right to seek contribution from any non-paying Subsidiary Guarantor, in a pro rata amount based on the net assets of each Subsidiary Guarantor determined in accordance with GAAP as in effect from time to time, so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantee.

(i) ninety-five per cent (95%) of the amount equal to the sum of the Luxembourg Subsidiary Guarantor’s capitaux propres (as referred to in article 34 of the Luxembourg law dated 19 December 2002 on the commercial register and annual accounts, as amended, and as implemented by the Grand-Ducal regulation dated 18 December 2015 setting out the form and the content of the presentation of the balance sheet and profit and loss account (the “Net Assets”)) and its debts which are subordinated in right of payment (whether generally or specifically) to any claim of any Holder of a Note under any of the Notes (including, for the avoidance of doubt, the amount of any Intra-Group Liabilities) (the “Subordinated Debts”), as reflected in the financial information of the Luxembourg Subsidiary Guarantor available as at the date of this Indenture, including, without limitation, its most recently and duly approved financial statements (comptes annuels) and any (unaudited) interim financial statements signed by its board of managers (conseil de gérance); and

(ii) ninety-five per cent (95%) of the amount equal to the Luxembourg Subsidiary Guarantor’s Net Assets and its Subordinated Liabilities, as reflected in the financial information of the Luxembourg Subsidiary Guarantor available as at the date the guarantee is called, including, without limitation, its most recently and duly approved financial statements (comptes annuels) and any (unaudited) interim financial statements signed by its board of managers (conseil de gérance).

(b) For this purpose, “Intra-Group Liabilities” shall mean any amounts owed by the Luxembourg Subsidiary Guarantor to any other member of the group and that have not been financed (directly or indirectly) by any amount made available under the Notes.

(c) Should the financial information referred to in clause (i) and (ii) above not be available on the date of this Indenture or on the date the guarantee is called, as the case may be, such financial information will be determined by the Trustee or any other person designated by the Trustee, acting reasonably, in accordance with the Luxembourg accounting principles applicable to the Luxembourg Subsidiary Guarantor and at the cost of the Luxembourg Subsidiary Guarantor.

(d) The limitation set forth in paragraph (a) above shall not apply to any amounts (i) due under the Notes by an entity which is a direct or indirect subsidiary of the Luxembourg Subsidiary Guarantor nor (ii) due under any Notes and which have been on-lent or made available, in any form whatsoever, to the Luxembourg Subsidiary Guarantor or any of its direct or indirect Subsidiaries.

Execution Version

(e) Notwithstanding anything to the contrary, the Luxembourg Subsidiary Guarantor does not guarantee any amounts due under the Notes if and to the extent the granting of a guarantee for such amounts would constitute an unlawful financial assistance violating, to the extent applicable, article 1500-7 of the Luxembourg law dated 10 August 1915 on commercial companies, as amended.

Section 12.03 Limitation on Subsidiary Guarantor Liability.

Each Subsidiary Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Subsidiary Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar Federal or state law to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors hereby irrevocably agree that the obligations of such Subsidiary Guarantor will be limited to the maximum amount which, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor, and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under this Article 12, will result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under Federal or state law. The obligations of the Estonian Subsidiary Guarantor under this Indenture shall not apply or extend to, and no guarantee granted by the Estonian Subsidiary Guarantor shall secure any liability to the extent undertaking such guarantee, indemnity or other obligations by the Estonian Subsidiary Guarantor would contravene or would not be in full compliance with the mandatory provisions of the Estonian Commercial Code (in Estonian: äriseadustik) regarding unlawful financial assistance (including prohibited guarantees).

Section 12.04 Execution and Delivery of Notation of Guarantee.

(a) To evidence its Subsidiary Guarantee set forth in Section 12.01, with respect to the Notes issued on the Issue Date, a Subsidiary Guarantor shall execute a notation of such Subsidiary Guarantee substantially in the form included in Exhibit D hereto endorsed by an Officer of such Subsidiary Guarantor by manual or facsimile signature on each Note authenticated and delivered by the Trustee.

(b) Each Subsidiary Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 12.01 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee.

(c) If an Officer whose signature is on this Indenture or on the Notation of Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Notation of Guarantee is endorsed, the Subsidiary Guarantee shall be valid nevertheless.

(d) The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantors.

Section 12.04 Releases of Subsidiary Guarantors.

A Subsidiary Guarantor will be deemed automatically and unconditionally released and discharged from all of its obligations under its Subsidiary Guarantee without any further action on the part of the Trustee or any Holder of the Notes:

Execution Version

(a) in the event that a Subsidiary Guarantor is sold or disposed of (whether by merger, consolidation, the sale of its Capital Stock or the sale of all or substantially all of its assets (other than by lease)), and whether or not the Subsidiary Guarantor is the surviving entity in such transaction to a Person which is not the Company or a Subsidiary of the Company, or upon its liquidation or dissolution; or

(b) upon a satisfaction and discharge of the Notes in accordance with Article 7.

Nothing herein shall preclude any tax withholding required by law or regulation. Each Holder agrees, and each beneficial owner of an interest in a Note by its acquisition of such interest is deemed to agree, that if the Company or other applicable withholding agent pays withholding taxes or backup withholding on behalf of the Holder or beneficial owner as a result of an adjustment to the Conversion Rate, the Company or other applicable withholding agent may, at its option, set off such payments against payments of cash and shares of Common Stock on the Note (or, in certain circumstances, against any payments on the Common Stock).

Section 13.11 Waiver of Jury Trial.

EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY.
