        "obligor" on the indenture securities means the Company. 

        All
other TIA terms used in this Indenture that are defined by the TIA, defined by a TIA reference to another statute or defined by an SEC rule have the meanings assigned to them by such
definitions. 

        SECTION
1.04.    Rules of Construction. Unless the context otherwise requires: 

        (a)   a
term has the meaning assigned to it; 

        (b)   an
accounting term not otherwise defined has the meaning assigned to it in accordance with generally accepted accounting principles as in effect from time to time; 

        (c)   "or" is not exclusive; 

        (d)   "including" means including, without limitation; and 

        (e)   words

        SECTION
1.05.    Acts of Holders. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby
expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 

        (b)   The
fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a
notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to such officer the execution thereof.
Where such execution is by a signer acting in a capacity other than such signer's individual capacity, such certificate or affidavit shall also constitute sufficient proof of such signer's authority. 

        The
fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems
sufficient. 

        (c)   The
ownership of Registered Securities shall be proved by the register maintained by the Registrar. 

        (d)   Any
request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and
the Holder of 

7

 

every
Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such Security. 

        (e)   If
the Company shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or
pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but
the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such
record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of
outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Securities
shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than six months after the record date. 

ARTICLE II

THE SECURITIES  

        SECTION 2.01.    Form and Dating. The Securities and the Trustee's certificate of authentication shall
be substantially in the forms set forth on Exhibits A-1 and A-2, which are a part of this Indenture and incorporated by reference herein. The Securities may have notations, legends or endorsements
required by law, stock exchange rule or usage; provided that any such notation, legend or endorsement required by usage is in a form acceptable to the Company. The Company shall provide any such
notations, legends or endorsements to the Trustee in a Company Order. Each Security shall be dated the date of its authentication. 

        (a)   144A Global Securities. Securities offered and sold to qualified institutional buyers as defined in Rule 144A
("QIBS") in reliance on Rule 144A shall be issued, initially in the form of a 144A Global Security, which shall be deposited with the Trustee at its
Corporate Trust Office, as custodian for the Depositary and registered in the name of The Depository Trust Company ("DTC") or the nominee thereof (such
depositary, or any successor thereto, and any such nominee being hereinafter referred to as the "Depositary"), duly executed by the Company and
authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the 144A Global Securities may from time to time be increased or decreased by adjustments made on the records of
the Trustee and the Depositary as hereinafter provided. 

        (b)   Global Securities in General. Each Global Security shall represent such of the outstanding Securities as shall be
specified therein and each shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding
Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions and conversions. 

        Any
adjustment of the aggregate principal amount of a Global Security to reflect the amount of any increase or decrease in the amount of outstanding Securities represented thereby shall
be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 hereof and shall be made on the records of the Trustee and the Depositary. 

        (c)   Book-Entry Provisions. The Company shall execute and the Trustee shall, in accordance with this Section 2.01(c),
authenticate and deliver initially one or more Global Securities that (a) 

8

 

shall
be registered in the name of the Depositary, (b) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary's instructions and (c) shall bear legends substantially to the
following effect: 

"UNLESS
THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO FIRST HORIZON PHARMACEUTICAL CORPORATION (THE "COMPANY") OR ITS AGENT FOR REGISTRATION OF
TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY
(AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS TO NOMINEES OF
THE DEPOSITORY TRUST COMPANY OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
RESTRICTIONS SET FORTH IN ARTICLE TWO OF THE INDENTURE REFERRED TO ON THE REVERSE HEREOF." 

        (d)   Certificated Securities. Securities not issued as interests in the Global Securities will be issued in certificated form
substantially in the form of Exhibit A-2 attached hereto. 

        SECTION
2.02.    Execution and Authentication. The Securities shall be executed on behalf of the Company by any Officer. The
signature of the Officer of the Company on the Securities may be manual or facsimile. 

        Securities
bearing the manual or facsimile signatures of individuals who were at the time of the execution of the Securities the proper Officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Securities or did not hold such offices at the date of authentication of such Securities. 

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

        The
Trustee shall authenticate and deliver Securities for original issue in an aggregate Principal Amount of up to $150,000,000 (which shall include the Initial Purchasers' option to
purchase $25,000,000 of additional Securities) upon a Company Order without any further action by the Company. The aggregate Principal Amount of Securities outstanding at any time may not exceed the
amount set forth in the foregoing sentence, except as provided in Section 2.07 

        The
Securities shall be issued only in registered form without coupons and only in denominations of $1,000 of Principal Amount and any integral multiple thereof. 

        SECTION
2.03.    Registrar, Paying Agent and Conversion Agent. The Company shall
maintain an office or agency where Securities may be presented for registration of transfer or for exchange ("Registrar"), an office or agency where
Securities may be presented for purchase or payment ("Paying Agent") and an office or agency where Securities may be presented for conversion
("Conversion  

9

 

 Agent"). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or more co-registrars, one or more additional paying
agents and one or more additional conversion agents. The term Paying Agent includes any additional paying agent, including any named pursuant to Section 4.05. The term Conversion Agent includes any
additional conversion agent, including any named pursuant to Section 4.05. 

        The
Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent, Conversion Agent or co-registrar (other than the Trustee). The agreement shall implement
the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee by a Company Order of the name and address of any such agent. If the Company fails to maintain a
Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Subsidiary or an
Affiliate of either of them may act as Paying Agent, Registrar, Conversion Agent or co-registrar. 

        The
Company initially appoints the Trustee as Registrar, Conversion Agent and Paying Agent in connection with the Securities. 

        SECTION
2.04.    Paying Agent to Hold Money in Trust. Except as otherwise provided herein, on or prior to each due date of
payments in respect of any Security, the Company shall deposit with the Paying Agent a sum of money (in immediately available funds) sufficient to make such payments when so becoming due. The Company
shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying
Agent for the making of payments in respect of the Securities and shall notify the Trustee of any Default by the Company in making any such payment. At any time during the continuance of any such
Default, the Paying Agent shall, upon the written request of the Trustee, forthwith pay to the Trustee all money so held in trust. If the Company, a Subsidiary or an Affiliate of either of them acts
as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the
Trustee and to account for any funds disbursed by it. Upon doing so, the Paying Agent shall have no further liability for the money. 

        SECTION
2.05.    Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most
recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall cause to be furnished to the Trustee at least semiannually in advance
of each interest payment date a listing of Securityholders dated within 15 days of the date on which the list is furnished and at such other times as the Trustee may request in writing a list in such
form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders. 

        SECTION
2.06.    Transfer and Exchange. (a) Subject to Section 2.12 hereof, upon surrender for registration of transfer of any
Securities, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Securityholder or such Securityholder's attorney duly authorized in writing, at the office
or agency of the Company designated as Registrar or co-registrar pursuant to Section 2.03, the Company shall execute and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of any authorized denomination or denominations, of a like aggregate Principal Amount. The Company shall not charge a service charge for any
registration of transfer or exchange, but the Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in connection with the
transfer or exchange of the Securities from the Securityholder requesting such transfer or exchange. 

        At
the option of the Holder, Securities may be exchanged for other Securities of any authorized denomination or denominations, of a like aggregate Principal Amount, upon surrender of the
Securities to be exchanged, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Securityholder or such Securityholder's attorney duly authorized in
writing, at such 

10

 

office
or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities that the Holder making the exchange
is entitled to receive. 

        The
Company shall not be required to make, and the Registrar need not register, transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be
redeemed in part, the portion thereof not to be redeemed) or any Securities in respect of which a Purchase Notice or Change in Control Purchase Notice has been given and not withdrawn by the Holder
thereof in accordance with the terms of this Indenture (except, in the case of Securities to be purchased in part, the portion thereof not to be purchased) or any Securities for a period of 15 days
before the mailing of a notice of redemption of Securities to be redeemed. 

        (b)   Notwithstanding
any provision to the contrary herein, so long as a Global Security remains outstanding and is held by or on behalf of the Depositary, transfers of a
Global Security, in whole or in part, shall be made only in accordance with Section 2.12 and this Section 2.06(b). Transfers of a Global Security shall be limited to transfers of such Global Security
in whole, or in part, to nominees of the Depositary or to a successor of the Depositary or such successor's nominee. 

        (c)   Successive
registrations and registrations of transfers and exchanges as aforesaid may be made from time to time as desired, and each such registration shall be noted on
the register for the Securities. 

        (d)   Any
Registrar appointed pursuant to Section 2.03 hereof shall provide to the Trustee such information as the Trustee may reasonably require in connection with the
delivery by such Registrar of Securities upon transfer or exchange of Securities. 

        (e)   No
Registrar shall be required to make registrations of transfer or exchange of Securities during any periods designated in the text of the Securities or in this
Indenture as periods during which such registration of transfers and exchanges need not be made. 

        (f)    If
Securities are issued upon the transfer, exchange or replacement of Securities subject to restrictions on transfer and bearing the legends set forth on the forms of
Securities attached hereto as Exhibits A-1 and A-2 setting forth such restrictions (collectively, the "Legend"), or if a request is made to remove the
Legend on a Security, the Securities so issued shall bear the Legend, or the Legend shall
not be removed, as the case may be, unless there is delivered to the Company and the Registrar such satisfactory evidence, which shall include an Opinion of Counsel, as may be reasonably required by
the Company and the Registrar, that neither the Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule
144 under the Securities Act or that such Securities are not "restricted" within the meaning of Rule 144 under the Securities Act. Upon (i) provision of such satisfactory evidence, or (ii)
notification by the Company to the Trustee and Registrar of the sale of such Security pursuant to a registration statement that is effective at the time of such sale, the Trustee, at the written
direction of the Company, shall authenticate and deliver a Security that does not bear the Legend. If the Legend is removed from the face of a Security and the Security is subsequently held by an
Affiliate of the Company, the Legend shall be reinstated. 

        SECTION
2.07.    Replacement Securities. If any mutilated Security is surrendered to the Trustee, or the Company and the Trustee
receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee such security or indemnity as may be required by them to
save each of them harmless, then, in the absence of actual knowledge by the Company or the Trustee that such Security has been acquired by a protected purchaser (within the meaning of Section 8-303 of
the Uniform Commercial Code), the Company shall execute, and upon the Company's written request the Trustee shall authenticate and deliver, in exchange for any such 

11

 

mutilated
Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and Principal Amount, bearing a number not contemporaneously outstanding. 

        In
case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be purchased by the Company pursuant to Article III
hereof, the Company in its discretion may, instead of issuing a new Security, pay or purchase such Security, as the case may be. 

        Upon
the issuance of any new Securities under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 

        Every
new Security issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all
other Securities duly issued hereunder. 

        The
provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities. 

        SECTION
2.08.    Outstanding Securities; Determinations of Holders' Action.
Securities outstanding at any time are all the Securities authenticated by the Trustee, except for those cancelled by it, those paid pursuant to Section 2.07, those delivered to it for cancellation
pursuant to Section 2.10 and those described in this Section 2.08 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security;
provided, however, that in determining whether the Holders of the requisite Principal Amount of Securities have given or concurred in any request, demand, authorization, direction, notice, consent or
waiver hereunder, Securities owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding,
except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Securities of which a Responsible
Officer of the Trustee has actual knowledge to be so owned shall be so disregarded. Subject to the foregoing, only Securities outstanding at the time of such determination shall be considered in any
such determination (including, without limitation, determinations pursuant to Articles VI and IX). 

        If
a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a protected
purchaser. 

        If
the Paying Agent holds, in accordance with this Indenture, on a Redemption Date, or on the Business Day following a Purchase Date or a Change in Control Purchase Date, or on Stated
Maturity, money sufficient to pay amounts owed with respect to Securities payable on that date, then immediately after such Redemption Date, Purchase Date, Change in Control Purchase Date or Stated
Maturity, as the case may be, such Securities shall cease to be outstanding and interest (including contingent interest, if any) and Liquidated Damages, if any, on such Securities shall cease to
accrue; provided that if such Securities are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee has been made. 

        If
a Security is converted in accordance with Article X, then from and after the time of conversion on the Conversion Date, such Security shall cease to be outstanding and interest
(including contingent interest, if any) and Liquidated Damages, if any, shall cease to accrue on such Security. 

12

   
        SECTION 2.09.    Temporary Securities. Pending the preparation of definitive Securities, the Company may execute, and upon
Company Order the Trustee shall authenticate and deliver, temporary Securities that are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing
such Securities may determine, as conclusively evidenced by their execution of such Securities. 

        If
temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary
Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 2.03,
without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a
like Principal Amount of definitive Securities of authorized denominations. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities. 

        SECTION
2.10.    Cancellation. All Securities surrendered for payment or purchase by the Company pursuant to Article III,
conversion, redemption or registration of transfer or exchange (other than Securities exchanged pursuant to Section 10.02), shall, if surrendered to any person other than the Trustee, be delivered to
the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder that the Company
may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. The Company may not issue new Securities to replace Securities it has paid or
delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article X. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as
provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with the Trustee's customary
procedure. 

        SECTION
2.11.    Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of the Principal
Amount of the Security or the payment of any Redemption Price, Purchase Price or Change in Control Purchase Price in respect thereof, and accrued and unpaid interest thereon, for the purpose of
conversion and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary. 

        SECTION
2.12.    Global Securities. (a) A Global Security may not be transferred, in whole or in part, to any Person other than
the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that the foregoing shall not prohibit any transfer of a Security that is
issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such
Security has been registered in the name of such Person. Notwithstanding any other provisions of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be made
only in accordance with Section 2.06 and this Section 2.12. 

        (b)   Subject
to the succeeding paragraph, every Security shall be subject to the restrictions on transfer provided in the Legend including the delivery of an Opinion of
Counsel, if so provided. Whenever any Restricted Security is presented or surrendered for registration of transfer or for exchange for a Security registered in a name other than that of the Holder,
such Security must be accompanied by a certificate in substantially the form set forth in Exhibit B, dated the date of such 

13

 

surrender
and signed by the Holder of such Security, as to compliance with such restrictions on transfer. The Registrar shall not be required to accept for such registration of transfer or exchange
any Security not so accompanied by a properly completed certificate. 

        (c)   The
restrictions imposed by the Legend upon the transferability of any Security shall cease and terminate when such Security has been sold pursuant to an effective
registration statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto) or, if earlier, upon the expiration of the
holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision). Any Security as to which such restrictions on transfer shall have expired in
accordance with their terms or shall have terminated may, upon a surrender of such Security for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the
event that such restrictions on transfer have terminated by reason of a transfer in compliance with Rule 144 or any successor provision, by an Opinion of Counsel having substantial experience in
practice under the Securities Act and otherwise reasonably acceptable to the Company, addressed to the Company and in form acceptable to the Company, to the effect that the transfer of such Security
has been made in compliance with Rule 144 or such successor provision), be exchanged for a new Security, of like tenor and aggregate Principal Amount, which shall not bear the Legend. The Company
shall inform the Trustee of the effective date of any registration statement registering the Securities under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be
taken by it in good faith in accordance with the aforementioned Opinion of Counsel or registration statement. 

        (d)   As
used in the preceding two paragraphs of this Section 2.12, the term "transfer" encompasses any sale, pledge, transfer, hypothecation or other disposition of any
Security. 

        (e)   The
provisions of clauses (i), (ii), (iii) and (iv) below shall apply only to Global Securities: 

          (i)  Notwithstanding
any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered in the
name of any Person other than the Depositary or one or more nominees thereof; provided that a Global Security may be exchanged for Securities registered in the names of any person designated by the
Depositary in the event that (x) the Depositary has notified the Company and the Trustee that it is unwilling or unable to continue as Depositary for such Global Security or such Depositary has ceased
to be a "clearing agency" registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days, (y) the Company has provided the Depositary and the Trustee with
written notice that it has decided to discontinue use of the system of book-entry transfer through the Depositary or any successor Depositary or (z) an Event of Default has occurred and is continuing
with respect to the Securities. Any Global Security exchanged pursuant to clause (x) or (y) above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause
(z) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security;
provided that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security. 

         (ii)  Securities
issued in exchange for a Global Security or any portion thereof shall be issued in definitive, fully registered form, without interest coupons, shall have an
aggregate Principal Amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary
shall designate and shall bear the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard
to any Global Security to be exchanged in part, either such Global Security shall 

14

 

be
so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the Principal Amount thereof shall be reduced, by an
amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate
and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof. 

        (iii)  Subject
to the provisions of clause (v) below, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members (as defined below)
and persons that may hold interests through Agent Members, to take any action which a holder is entitled to take under this Indenture or the Securities. 

        (iv)  In
the event of the occurrence of any of the events specified in clause (i) above, the Company will promptly make available to the Trustee a reasonable supply of
Certificated Securities in definitive, fully registered form, without interest coupons. 

         (v)  Neither
any members of, or participants in, the Depositary (collectively, the "Agent Members") nor any other Persons on
whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or under any such
Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such
Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other person on
whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Security.

correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the CUSIP numbers.

the Holders in whose names the Securities are registered at the close of business on the relevant record date for payment of such interest. 

        (b)   Notice to Trustee. If the Company elects to redeem Securities pursuant to this Section 3.01, it shall notify the Trustee

        SECTION
3.02.    Selection of Securities to Be Redeemed. If less than all the Securities are to be redeemed, unless the
procedures of the Depositary provide otherwise, the Trustee shall select the Securities to be redeemed on a pro rata basis. The Trustee may select for redemption portions of the Principal Amount of

        Securities
and portions of them the Trustee selects shall be in Principal Amounts of $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to Securities
called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed. 

        If
any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted
portion of such Security shall be deemed (so far as possible) to be the portion selected for redemption. Securities that have been converted during a selection of Securities to be redeemed may be
treated by the Trustee as outstanding for the purpose of such selection. 

        SECTION
3.03.    Notice of Redemption. At least 20 days (and, in the case of DTC eligible Securities, at least 30 days) but not
more than 60 days before a Redemption Date, the Company shall mail a notice of redemption by first-class mail, postage prepaid, to each Holder of Securities to be redeemed.

        (f)    that
Holders who want to convert Securities must satisfy the requirements set forth in paragraph 8 of the Securities; 

        (g)   that
Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price therefor, together with all accrued and unpaid interest; 

        (h)   if
fewer than all the outstanding Securities are to be redeemed, the certificate numbers, if any, and Principal Amounts of the particular Securities to be redeemed; 

        (i)    that,
unless the Company defaults in making payment of such Redemption Price, interest (including contingent interest, if any) and Liquidated Damages, if any, on
Securities called for redemption will cease to accrue on and after the Redemption Date and the Securities will cease to be convertible; and 

        (j)    the
CUSIP number of the Securities. 

        At
the Company's request, the Trustee shall give the notice of redemption in the Company's name and at the Company's expense; provided that the Company makes such request prior to the
date by which such notice of redemption must be given to Holders in accordance with this Section 3.03 and the Company provides the Trustee with all information required for such notice of redemption.

        SECTION
3.04.    Effect of Notice of Redemption. Once notice of redemption is given, Securities called for redemption become due

Paying Agent, such Securities shall be paid at the Redemption Price stated in the notice, together with accrued and unpaid interest (including contingent interest, if any) and Liquidated Damages, if
any, thereon, up to but not including the Redemption Date. 

        SECTION

funds sufficient to pay the Redemption Price of all Securities to be redeemed on that date, together with accrued and unpaid interest (including contingent interest, if any) and Liquidated Damages, if
any, thereon, up to but not including the Redemption Date other than Securities or portions of Securities called for redemption that on or prior thereto have been delivered by the Company to the
Trustee for cancellation or have been converted. The Paying Agent shall as
promptly as practicable return to the Company any money not required for that purpose because of conversion of Securities pursuant to Article X. If such money is then held by the Company in trust and
is not required for such purpose it shall be discharged from such trust. 

        SECTION
3.06.    Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Company shall execute

        The
Company shall purchase from the Holder thereof, pursuant to this Section 3.08, a portion of a Security if the Principal Amount of such portion is $1,000 or an integral multiple of
$1,000. Provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of such Security. 

        Any
purchase by the Company contemplated pursuant to the provisions of this Section 3.08 shall be consummated by the delivery of the consideration to be received by the Holder promptly
following the later of the Purchase Date and the time of delivery of the Security. 

        Notwithstanding

quarterly reports, information, documents and other reports with the SEC, copies of its annual report and of the information, documents and other reports (or copies of such portions of any of the
foregoing as the SEC may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. In the event the Company is at any
time no longer subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, it shall continue to provide the Trustee with reports containing substantially the same information as
would have been required to be filed with the SEC had the Company continued to have been subject to such reporting requirements. In such event, such reports shall be provided to the Trustee at the
times the Company would have been required to provide reports had it continued to have been subject to such reporting requirements. Delivery of such reports, information and documents is for
informational purposes only and the Trustee's receipt of such shall not constitute notice or constructive notice of any information contained therein or determinable from information contained
therein. 

        In
addition, the Company shall comply with the other provisions of TIA Section 314(a). 

        SECTION
4.03.    Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal
year of the Company (beginning with the fiscal year ended December 31, 2004) an Officers' Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in
the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and if the Company
shall be in default, specifying all such Defaults and the nature and status thereof of which they may have knowledge. 

        SECTION
4.04.    Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further
instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 

        SECTION
4.05.    Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, The City of New York,
an office or agency of the Trustee, Registrar, Paying Agent and Conversion Agent where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of
transfer, exchange, purchase, redemption or conversion and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Corporate Trust Office of
the Trustee shall initially be such office or agency for all of the aforesaid purposes. The Company shall give prompt written notice to the Trustee of the location, and of any change in the location,
of any such office or agency (other than a change in the location of the office of the Trustee). If at any time the Company shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 12.02. 

23

   
        The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time
to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York, for such purposes. 

        SECTION
4.06.    Delivery of Certain Information. At any time when the Company is not subject to Section 13 or 15(d) of the
Exchange Act, upon the request of a Holder or any beneficial owner of Securities or holder or beneficial owner of Common Stock delivered upon conversion thereof, the Company will promptly furnish or
cause to be furnished Rule 144A Information (as defined below) to such Holder or any beneficial owner of Securities or holder or beneficial owner of Common Stock, or to a prospective purchaser of any
such security designated by any such holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the
resale of any such security. "Rule 144A Information" shall be such information as is specified pursuant to Rule 144A(d)(4) under the Securities Act or
any successor provisions. Whether a person is a beneficial owner shall be determined by the Company to the Company's reasonable satisfaction. 

        SECTION
4.07.    Tax Treatment of Securities. The Company and the Holders, by purchasing the Securities, agree that (i) the
Securities are contingent payment debt instruments as described in Treasury Regulations Section 1.1275-4, (ii) each Holder shall be bound by the Company's application of the Treasury Regulations to
the Securities, including the Company's determination that the rate at which interest will be deemed to accrue on the Securities for United States federal income tax purposes, will be 9.15% compounded
semiannually, which is the rate comparable to the rate at which the Company would borrow on a noncontingent, nonconvertible borrowing with no contingent payments, but with terms and conditions
otherwise comparable to the Securities, (iii) each Holder shall use the projected payment schedule with respect to the Securities provided by the Company to the Holder, as provided in Treasury
Regulations Section 1.1275-4(b)(4), to determine its interest accruals and adjustments as provided in Treasury Regulations Section 1.1275-4(b)(4)(iv), (iv) for purposes of Treasury Regulations Section
1.1275-4, to treat the fair market value of any Common Stock received upon any conversion of the Securities as a contingent payment, and (v) the Company and each Holder will not take any position on a
tax return inconsistent with (i), (ii), or (iii), unless required by applicable law. 

        On
conversion of the Securities, that portion of accrued interest including accrued contingent interest with respect to the converted Securities shall not be canceled, extinguished or
forfeited, but rather shall be deemed to be paid in full to the Holder thereof through delivery of the Common Stock (together with the cash payment, if any, in lieu of fractional shares) in exchange
for the Securities being converted pursuant to the provisions hereof, and the fair market value of such shares of Common Stock (together with any such cash payment in lieu of fractional shares) shall
be treated as issued, to the extent thereof, first in exchange for interest accrued and unpaid through the conversion date and
accrued and unpaid contingent interest, and the balance, if any, of such fair market value of such Common Stock (and any such cash payment) shall be treated as issued in exchange for the principal
amount of the Securities being converted pursuant to the provisions hereof. 

        SECTION
4.08.    Liquidated Damages. If at any time Liquidated Damages become payable by the Company pursuant to the
Registration Rights Agreement, the Company shall promptly deliver to the Trustee an Officer's Certificate to that effect and stating (i) the amount of such Liquidated Damages that are payable and (ii)
the date on which such damages are payable pursuant to the terms of the Registration Rights Agreement. Unless and until a Responsible Officer of the Trustee receives such Officer's Certificate, the
Trustee may assume without inquiry that no Liquidated Damages are payable. If the Company has paid Liquidated Damages directly to the persons entitled to them, the Company shall deliver to the Trustee
a certificate setting forth the particulars of such payment.

        SECTION 5.01.    When the Company May Merge or Transfer Assets. The Company shall not consolidate with

         (ii)  immediately
after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing; and 

        (iii)  the
Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer
or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this Article V and that all conditions precedent herein provided for
relating to such transaction have been satisfied. 

        For
purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise) of the properties and assets of one or more Subsidiaries (other than to the Company or another
Subsidiary), which, if such assets were owned by the Company would constitute all or substantially all of the properties and assets of the Company shall be deemed to be the transfer of all or
substantially all of the properties and assets of the Company. 

        The
successor person formed by such consolidation or into which the Company is merged or the successor person to which such conveyance, transfer or lease is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor had been named as the Company herein; and thereafter, except in
the case of a lease and obligations the Company may have under a supplemental indenture pursuant to Section 10.12, the Company shall be discharged from all obligations and covenants under this
Indenture and the Securities. Subject to Section 9.06, the Company, the Trustee and the successor person shall enter into a supplemental indenture to evidence the succession and substitution of such
successor person and such discharge and release of the Company.

        The
Company shall deliver to the Trustee, within 30 days after it becomes aware of the occurrence thereof, written notice of any event which with the giving of notice or the lapse of

become an Event of Default under clause (c) or (d) above, its status and what action the Company is taking or proposes to take with respect thereto. 

        SECTION
6.02.    Defaults and Remedies. If an Event of Default (other than an Event of Default specified in Section 6.01(i) or
6.01(j)) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in aggregate Principal Amount of the Securities at the time outstanding by notice to the Company
and the Trustee, may declare the Principal Amount of all the Securities plus accrued and unpaid interest (including contingent interest, if any) and Liquidated Damages, if any, thereon, through the
date of declaration to be immediately due and payable. Upon such a declaration, such Principal Amount plus accrued and unpaid interest (including contingent interest, if any) and Liquidated Damages,
if any, shall become and be immediately due and payable subject to the provisions of Article XI. If an Event of Default specified in Section 6.01(i) or 6.01(j) occurs and is 

26

 

continuing,
the Principal Amount of all the Securities plus accrued and unpaid interest (including contingent interest, if any) and Liquidated Damages, if any, thereon, shall become and be immediately
due and payable without any declaration or other act on the part of the Trustee or any Securityholder. 

        The
Holders of a majority in principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing Events of
Default, other than the nonpayment of the principal of and accrued and unpaid interest (including contingent interest, if any) and Liquidated Damages, if any, on the Securities which has become due
solely by such declaration of acceleration, have been cured or waived; (b) the Company has paid or deposited with the Trustee a sum in immediately available funds sufficient to pay (i) all overdue
interest (including contingent interest, if any) and Liquidated Damages, if any, on the Securities, (ii) the principal of any Security which has become due otherwise than by such declaration of
acceleration, and (iii) to the extent the payment of such interest is lawful, interest on overdue installments of interest and Liquidated Damages, if any, and overdue principal, which has become due
otherwise than by such declaration of acceleration; (c) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (d) all payments due to the Trustee and
any predecessor Trustee under Section 7.07 have been made. No such rescission shall affect any subsequent Default or Event of Default or impair any right consequent thereon. 

        SECTION
6.03.    Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to
collect the payment of the Principal Amount of all the Securities, together with all accrued and unpaid interest (including contingent interest, if any) and Liquidated Damages, if any, thereon or to
enforce the performance of any provision of the Securities or this Indenture. 

        The
Trustee may maintain a proceeding even if the Trustee does not possess any of the Securities or does not produce any of the Securities in the proceeding. A delay or omission by the
Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the
right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. 

        SECTION
6.04.    Waiver of Past Defaults. The Holders of a majority in aggregate Principal Amount of the Securities at the time
outstanding, by notice in writing to the Trustee (and without notice to any other Securityholder), may waive an existing Default and its consequences, except (a) an Event of Default described in
Section 6.01(a) or 6.01(b), (b) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Securityholder affected or (c) a Default which constitutes a
failure to convert any Security in accordance with the terms of Article X. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair
any consequent right. This Section 6.04 shall be in lieu of Section 316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) is hereby expressly excluded from this Indenture, as permitted by the TIA. 

        SECTION
6.05.    Control by Majority. The Holders of a majority in aggregate Principal Amount of the Securities at the time
outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the
Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Securityholders or would
involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it. This Section 6.05 shall be in lieu of Section 316(a)(1)(A) of the TIA and such Section
316(a)(1)(A) is hereby expressly excluded from this Indenture, as permitted by the TIA. 

27

 

        SECTION
6.06.    Limitation on Suits. A Securityholder may not pursue any remedy with respect to this Indenture or the
Securities unless: 

        (a)   the
Holder gives to the Trustee written notice stating that an Event of Default is continuing; 

        (b)   the
Holders of at least 25% in aggregate Principal Amount of the Securities at the time outstanding make a written request to the Trustee to pursue the remedy; 

        (c)   such
Holder or Holders offer to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense; 

        (d)   the
Trustee does not comply with the request within 60 days after receipt of such notice, request and offer of security or indemnity; and 

        (e)   the
Holders of a majority in aggregate Principal Amount of the Securities at the time outstanding do not give the Trustee a direction inconsistent with the request
during such 60-day period. 

        A
Securityholder may not use this Indenture to prejudice the rights of any other Securityholder or to obtain a preference or priority over any other Securityholder. 

        SECTION
6.07.    Rights of Holders to Receive Payment. Subject to the provisions of Article XI hereof, notwithstanding any other
provision of this Indenture, the right of any Holder to receive payment of any amount due in respect of the Securities held by such Holder, on or after the respective due dates expressed in the
Securities, and to convert the Securities in accordance with Article X, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be
impaired or affected adversely without the consent of such Holder. 

        SECTION
6.08.    Collection Suit by Trustee. If an Event of Default described in Section 6.01(a), 6.01(b) or 6.01(g) occurs and
is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount owing with respect to the Securities and the amounts
provided for in Section 7.07. 

        SECTION
6.09.    Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such
other obligor or their creditors, the Trustee (irrespective of whether interest installments (including contingent interest, if any), Liquidated Damages, if any, the Principal Amount, Redemption
Price, Purchase Price, Change in Control Purchase Price or interest, if any, due on overdue amounts in respect of the Securities shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any such amount) shall be entitled and empowered, by intervention in such proceeding or
otherwise, 

	(a)
	to
file and prove a claim for any accrued and unpaid interest installments (including contingent interest, if any), Liquidated Damages, if any, the whole amount of the Principal
Amount, Redemption Price, Purchase Price, Change in Control Purchase Price or interest, if any, due on overdue amounts in respect of the Securities, and to file such other papers or documents as may
be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel
or any other amounts due the Trustee under Section 7.07) and of the Holders allowed in such judicial proceeding, and

	(b)
	to
collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; 

28

 

and
any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. 

        Nothing
herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

        SECTION

following order: 

FIRST:
to the Trustee for amounts due under Section 7.07;

THIRD:
to Securityholders for amounts due and unpaid on the Securities for any accrued and unpaid interest installments (including contingent interest, if any), the Principal Amount, Redemption Price,
Purchase Price, Change in Control Purchase Price or interest, if any, due on overdue amounts in respect of the Securities, as the case may be, ratably, without preference or priority of any kind,
according to such amounts due and payable on the Securities; and 

FOURTH:
the balance, if any, to the Company. 

        The
Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. At least 15 days before such record date, the Trustee shall mail to
each Securityholder and the Company a notice that states the record date, the payment date and the amount to be paid. 

        SECTION
6.11.    Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any
suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant (other than the Trustee) in the suit of an undertaking
to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in the suit, having due regard
to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by
Holders of more than 10% in aggregate Principal Amount of the Securities at the time outstanding. This Section 6.11 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby
expressly excluded from this Indenture, as permitted by the TIA. 

        SECTION
6.12.    Waiver of Stay, Extension or Usury Laws. The Company covenants
(to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any
usury or other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company from paying all or any portion of any interest installment (including contingent
interest, if any), Liquidated Damages, if any, the Principal Amount, Redemption Price, Purchase Price, Change in Control Purchase Price or interest, if any, due on overdue amounts in respect of the
securities, as contemplated herein, or which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every
such power as though no such law had been enacted.

	the
Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request,
direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled, during normal business hours, to examine the books,
records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or
investigation;

	(i)
	the
Trustee shall not be deemed to have notice or knowledge of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless
written notice of any event which is in fact such a Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture;

	(j)
	the
rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in
each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder;

	(k)
	the
Trustee may request that the Company deliver an Officers' Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified
actions 

31

 

pursuant
to this Indenture, which Officers' Certificate may be signed by any person authorized to sign an Officers' Certificate, including any person specified as so authorized in any such certificate
previously delivered and not superseded; and 

	(l)
	neither
the Trustee nor any of its officers, directors, employees or agents shall be liable for any action taken or omitted under this Indenture or in connection therewith except to
the extent caused by the Trustee's gross negligence, bad faith or willful misconduct, as determined by the final judgment of a court of competent jurisdiction, no longer subject to appeal or review.
Anything in this Indenture to the contrary notwithstanding, in no event shall the Trustee be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not
limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 

        SECTION
7.03.    Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, Conversion Agent or co-registrar
may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. 

        SECTION
7.04.    Trustee's Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or
the Securities, it shall not be accountable for the Company's use or application of the proceeds from the Securities, it shall not be responsible for any statement in any registration statement for
the Securities under the Securities Act or in any offering document for the Securities, the Indenture or the Securities (other than its certificate of authentication), or the determination as to which
beneficial owners are entitled to receive any notices hereunder. 

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

32

   
        SECTION 7.06.    Reports by Trustee to Holders. Within 60 days after each March 31 beginning with the March 31 following the
date of this Indenture, the Trustee shall mail to each Securityholder a brief report dated as of such March 31 that complies with TIA Section 313(a), if required by such Section 313(a). The Trustee
also shall comply with TIA Section 313(b). 

        A
copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each securities exchange, if any, on which the Securities are listed. The Company
agrees to notify the Trustee promptly whenever the securities become listed on any securities exchange and of any delisting thereof. 

        SECTION
7.07.    Compensation and Indemnity. The Company agrees: 

	(a)
	to
pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation as the Company and the Trustee shall from time to time agree in writing for all
services rendered by it hereunder (which compensation shall not be limited (to the extent permitted by law) by any provision of law in regard to the compensation of a trustee of an express trust);

	(b)
	to
reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture or
any documents executed in connection herewith (including the reasonable compensation and the expenses, advances and disbursements of its agents and counsel), except any such expense, disbursement or
advance as may be attributable to its negligence, bad faith or willful misconduct; and

	(c)
	to
indemnify the Trustee or any predecessor Trustee and their agents, officers, directors and employees for, and to hold them harmless against, any loss, damage, claim, liability,
cost or expense (including attorneys' fees and expenses and taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) incurred without negligence, misconduct or bad
faith on its part, arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending itself against any claim (whether asserted by the
Company or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder. 

        To
secure the Company's payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except
that held in trust to pay interest installments (including contingent interest, if any), Liquidated Damages, if any, the Principal Amount, Redemption Price, Purchase Price, Change in Control Purchase
Price or interest, if any, due on overdue amounts, as the case may be, in respect of any particular Securities. 

        The
Company's payment obligations pursuant to this Section 7.07 shall survive the discharge of this Indenture or the earlier termination or resignation of the Trustee. When the Trustee
incurs expenses after the occurrence of a Default specified in Section 6.01(e) or Section 6.01(f), the expenses, including the reasonable charges and expenses of its counsel, are intended to
constitute expenses of administration under any bankruptcy law. 

        SECTION
7.08.    Replacement of Trustee. The Trustee may resign by so notifying the Company; provided, however, that no such
resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 7.08. The Holders of a majority in aggregate Principal Amount of the Securities at the
time outstanding may remove the Trustee by so notifying the Trustee and the Company. The Company shall remove the Trustee if: 

	(a)
	the
Trustee fails to comply with Section 7.10;

	(b)
	the
Trustee is adjudged bankrupt or insolvent; 

33

 

	(c)
	a
receiver or public officer takes charge of the Trustee or its property; or

	(d)
	the
Trustee otherwise becomes incapable of acting. 

        If
the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint, by resolution of its Board of Directors, a
successor Trustee. 

        A
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company satisfactory in form and substance to the retiring Trustee and the
Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee,
subject to the lien provided for in Section 7.07. 

        If
a successor Trustee does not take office within 30 days after the retiring Trustee gives its notice of resignation or is removed, the retiring Trustee, the Company or the Holders of a
majority in aggregate Principal Amount of the Securities at the time outstanding may petition any court of competent jurisdiction at the expense of the Company for the appointment of a successor
Trustee. 

        If
the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee. 

        SECTION
7.09.    Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or
substantially all its corporate trust business or assets (including the administration of the trust created by this Indenture) to, another corporation, the resulting, surviving or transferee
corporation without any further act shall be the successor Trustee. 

        SECTION
7.10.    Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA Section
310(a)(1). The Trustee (or its parent holding company) shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. Nothing
herein contained shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA Section 310(b). The Trustee shall comply with TIA Section 310(b);
provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in
other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. 

        SECTION
7.11.    Preferential Collection of Claims Against Company. The Trustee shall comply with TIA Section 311(a), excluding
any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. 

ARTICLE VIII

DISCHARGE OF INDENTURE  

        SECTION 8.01.    Discharge of Liability on Securities. When (i) the Company delivers to the Trustee all
outstanding Securities (other than Securities replaced pursuant to Section 2.07) for cancellation or (ii) all outstanding Securities have become due and payable and the Company deposits with the
Trustee Cash, in immediately available funds, sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.07), and if in either case
the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 7.07, cease to be of further effect. The Trustee shall join in the execution of a
document prepared by the Company acknowledging satisfaction and discharge of this Indenture on demand at the cost and expense of the Company and accompanied by an Officers' Certificate and Opinion of
Counsel. 

34

 

        SECTION
8.02.    Repayment to the Company. The Trustee and the Paying Agent shall return to the Company upon written request any
money held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, as
applicable, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person and the Trustee and the Paying
Agent shall have no further liability to the Securityholders with respect to such money or securities for that period commencing after the return thereof. 

ARTICLE IX

        SECTION 9.01.    Without Consent of Holders. The Company and the Trustee may amend or supplement this
Indenture or the Securities without notice to or consent of any Securityholder:

	(h)
	to
comply with the provisions of the TIA, or with any requirement of the SEC arising as a result of the qualification of this Indenture under the TIA. 

        SECTION
9.02.    With Consent of Holders. The Company and the Trustee may amend or supplement this Indenture or the Securities
without notice to any Securityholder but with the written consent of the Holders of a majority in aggregate Principal Amount of the Securities then outstanding. The Holders of a majority in aggregate
Principal Amount of the Securities then outstanding may waive compliance by the Company with restrictive provisions of this Indenture other than as set forth in this Section 9.02 below, and waive any
past Default under this Indenture and its consequences, except a Default in the payment of the principal of or interest on any Security or in respect of a provision which under this Indenture cannot
be modified or amended without the consent of the Holder of each outstanding Security affected. 

        Subject
to Section 9.04, without the written consent of each Securityholder affected, however, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not: 

	(a)
	change
the Stated Maturity of the principal of, or any payment date of any installment of interest (including contingent interest, if any) or Liquidated Damages, if any, on, any
Security;

	(b)
	reduce
the principal amount of, or the rate of interest (including contingent interest, if any) or Liquidated Damages, if any, on, any Security, whether upon acceleration, redemption
or otherwise, or alter the manner of calculation of interest or Liquidated Damages, if any, or the rate of accrual thereof on any Security;

	(c)
	change
the currency for payment of principal of, or interest (including contingent interest, if any) or Liquidated Damages, if any, on any Security; 

35

 

	(d)
	impair
the right to institute suit for the enforcement of any payment of principal of, or interest (including contingent interest, if any) or Liquidated Damages, if any, on, any
Security when due;

	(e)
	adversely
affect the conversion rights provided in Article X;

	(f)
	modify
Article XI in a manner adverse to the rights of the Holders of the Securities;

	(g)
	modify
the provisions of this Indenture requiring the Company to make an offer to repurchase Securities upon a Change in Control or to repurchase the Securities at the option of the
Holders pursuant to Section 3.08 in any case in a manner adverse to the Holders of the Securities;

	(h)
	reduce
the percentage of principal amount of the outstanding Securities necessary to modify or amend this Indenture or to consent to any waiver provided for in this Indenture;

	(i)
	waive
a Default in the payment of the principal amount of, or interest (including contingent interest, if any) or Liquidated Damages, if any, on, any Security (except as provided in
Section 6.02); or

	(j)
	make
any changes in Section 6.04, Section 6.07 or this Section 9.02. 

        It
shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be
sufficient if such consent approves the substance thereof. 

        After
an amendment under this Section 9.02 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. Failure to mail the notice or a defect in
the notice shall not effect the validity of the amendment. 

        SECTION
9.03.    Compliance with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article IX shall
comply with the TIA. 

        SECTION
9.04.    Revocation and Effect of Consents. Until an amendment, waiver or other action by Holders becomes effective, a
consent thereto by a Holder of a Security hereunder is a continuing consent by the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same obligation as
the consenting Holder's Security, even if notation of the consent, waiver or action is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent, waiver or action
as to such Holder's Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment, waiver or action becomes effective. After an amendment, waiver
or action becomes effective, it shall bind every Securityholder. 

        SECTION
9.05.    Notation on or Exchange of Securities. Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article IX may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Company shall so determine, new Securities so modified as to conform, in the opinion of the Trustee and the Board of Directors of the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for outstanding Securities. 

        SECTION
9.06.    Trustee to Sign Supplemental Indentures. The Trustee shall sign any supplemental indenture authorized pursuant
to this Article IX if the amendment contained therein does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign such
supplemental indenture. In signing such supplemental indenture the Trustee shall receive, and (subject to the provisions of Section 7.01) shall be fully protected in relying upon, an Officers'
Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture. 

36

 

        SECTION
9.07.    Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article IX, this
Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes, and every Holder of Securities theretofore or thereafter
authenticated and delivered hereunder shall be bound thereby. 

ARTICLE X

CONVERSIONS  

        SECTION 10.01.    Conversion Privilege. Subject to the provisions of this Article X, a Holder of a
Security may convert such Security into Common Stock (the shares of Common Stock issuable upon such conversion, the "Conversion Shares"), at the
Conversion Price then in effect, together with those rights, warrants or options specified in Section 10.06 hereof, to the extent applicable, if any of the following conditions is satisfied: 

	(a)
	during
any calendar quarter (the "Quarter") commencing after June 30, 2004, if the Closing Price (as defined hereinafter) per share of
Common Stock for at least 20 Trading Days in the period of 30 consecutive Trading Days ending on the last Trading Day of the Quarter preceding the Quarter in which the conversion of such Security
occurs is more than 120% of the Conversion Price on such thirtieth Trading Day;

	(b)
	the
Security has been called for redemption by the Company pursuant to Section 3.01;

	(c)
	the
conversion of such Security occurs during the five Trading Day period immediately following a period of nine consecutive Trading Days in which the Security Trading Price (as
determined following a request by a Holder of the Securities in accordance with the procedures set forth below in this Section 10.01) for each Trading Day in such period was less than 95% of the
product of the Closing Price per share of Common Stock on such Trading Day multiplied by the number of shares of Common Stock issuable (assuming satisfaction of conditions to conversion) upon
conversion of $1,000 in principal amount of the Securities (the condition specified in this clause (e) being the "95% Trading Condition");

	(d)
	(i)
an issuance of rights, warrants or options referred to in Section 10.06(b) occurs or (ii) a distribution referred to in Section 10.06(c) occurs where the fair market value of such
distribution per share of Common Stock (as determined by the Board of Directors of the Company, which determination shall be conclusive evidence of such fair market value) exceeds 5% of the Closing
Price per share of Common Stock on the Trading Day immediately preceding the date of declaration of such distribution; or

	(e)
	(x)
the Company is party to a consolidation, merger, share exchange, sale of all or substantially all of its assets or other similar transaction pursuant to which the Common Stock is
subject to conversion into shares of stock, other securities or property (including cash) pursuant to Section 10.12 and (y) the conversion of such Security occurs at any time from and after the date
that is 15 days prior to the date of the anticipated effective time of such transaction until and including the date that is 15 days after the actual effective date of such transaction. 

        In
connection with the foregoing clause (a), at the end of each Quarter the Conversion Agent shall, on the Company's behalf, determine whether the Securities are convertible in the
subsequent Quarter pursuant to such clause (a), and promptly notify the Holders if the Securities are convertible. 

        In
the case of the foregoing clauses (d)(i) and (ii), the Company must notify the Holders at least 20 days prior to the ex-dividend date for such issuance or distribution. Once the
Company has given such notice, Holders may surrender their Securities for conversion at any time thereafter until the earlier of the close of business on the Business Day prior to the ex-dividend date
or the Company's 

37

 

announcement
that such issuance or distribution will not take place. This provision shall not apply if the Holder of a Security otherwise participates in the distribution without conversion. 

        The
"Ex-Dividend Date" for any such issuance or distribution means the date immediately prior to the commencement of "ex-dividend" trading
for such issuance or distribution on the New York Stock Exchange or such other national securities exchange or The NASDAQ Stock Market or similar system
of automated dissemination of quotations of securities prices on which the Common Stock is then listed or quoted. 

        The
number of shares of Common Stock issuable upon conversion of a Security shall be determined by dividing the principal amount of the Security or portion thereof surrendered for
conversion by the Conversion Price in effect on the Conversion Date. The initial Conversion Price is set forth in paragraph 8 of the Securities and is subject to adjustment as provided in this Article
X. 

        A
Holder may convert a portion of a Security equal to $1,000 or any integral multiple thereof. Provisions of this Indenture that apply to conversion of all of a Security also apply to
conversion of a portion of a Security. 

        If
a Security is called for redemption pursuant to Article III, the right to convert such Security shall terminate at the close of business on the second Business Day before the
Redemption Date for such Security (unless the Company shall default in making the redemption payment then due, in which case the conversion right shall terminate on the date such Default is cured and
such Security is redeemed). A Security in respect of which a Holder has delivered a Purchase Notice pursuant to Section 3.08 or a Change in Control Purchase Notice pursuant to Section 3.09 exercising
the option of such Holder to require the Company to repurchase such Security may be converted only if such Purchase Notice or Change in Control Purchase Notice, as the case may be, is withdrawn by a
written notice of withdrawal delivered to the Paying Agent prior to the close of business on the Business Day prior to the Purchase Date or prior to the close of business on the Change in Control
Purchase Date, as the case may be, in accordance with Section 3.10. 

        A
Holder of Securities is not entitled to any rights of a holder of Common Stock until such Holder has converted its Securities into Common Stock and, upon such conversion, only to the
extent such Securities are deemed to have been converted into Common Stock pursuant to this Article X. 

        The
"Security Trading Price" per $1,000 in Principal Amount of Securities on any date of determination means the average of the secondary
market bid quotations per $1,000 in principal amount of Securities obtained by the Conversion Agent for $5,000,000 in principal amount of Securities at approximately 3:30 p.m., New York City time, on
such determination date from three independent nationally recognized securities dealers selected by the Company; provided that if at least three such bids cannot reasonably be obtained by the
Conversion Agent, but two such bids are obtained, then the average of the two bids shall be used, and if only one such bid can reasonably be obtained by the Conversion Agent, such one bid shall be
used. If the Conversion Agent cannot reasonably obtain at least one bid for $5,000,000 in principal amount of Securities from a nationally recognized securities dealer or, in the reasonable judgment
of the Company, the bid quotations are not indicative of the secondary market value of the Securities, then the Security Trading Price will be determined in good faith by the calculation agent (which
shall initially be the Trustee unless the Trustee shall have appointed a calculation agent, which may be any investment bank with a national or international reputation with experience in such
matters, including an Initial Purchaser or its successors) taking into account in such determination such factors as it, in its sole discretion after consultation with the Company, deems appropriate.
Other than in connection with a determination of whether contingent interest shall be payable, the Conversion Agent shall have no obligation to determine the Security Trading Price unless the Company
has requested such determination; and the Company shall have no obligation to make such request unless a Holder of the Securities provides the Company with reasonable evidence that the Security
Trading Price would be less than 95% of the product of the 

38

 

Closing
Price per share of the Common Stock and the number of shares of Common Stock issuable upon conversion of $1,000 in principal amount of Securities (assuming satisfaction of conditions to such
conversion); at which time the Company shall instruct the Conversion Agent to determine the Security Trading Price beginning on the next Trading Day and on each successive Trading Day until the
Security Trading Price is greater than or equal to 95% of the product of the Closing Price per share of Common Stock and the number of shares of Common Stock issuable upon conversion of $1,000 in
principal amount of Securities (assuming satisfaction of conditions to such conversion). 

        SECTION
10.02.    Conversion Procedure. To convert a Security, a Holder must satisfy the requirements in paragraph 8 of the
Securities and (i) complete and manually sign the conversion notice on the back of the Security and deliver such notice to the Conversion Agent, (ii) surrender the Security to the Conversion Agent,
(iii) furnish appropriate endorsements and transfer documents if required by the Registrar or the Conversion Agent, (iv) pay any transfer or other tax, if required by Section 10.04 and (v) if the
Security is held in book-entry form, complete and deliver to the Depositary appropriate instructions pursuant to the Depositary's book-entry conversion programs. The date on which the Holder satisfies
all of the foregoing requirements is the "Conversion Date". As soon as practicable after the Conversion Date, the Company shall deliver to the Holder
through the Conversion Agent either (i) a certificate for or (ii) a book-entry notation of the number of whole shares of Common Stock issuable upon the conversion and cash in lieu of any fractional
shares pursuant to Section 10.05; provided, however, that in the event of a Principal Value Conversion referred to below in this Section 10.02, the Company shall deliver to the Holder through the
Conversion Agent such cash and/or Common Stock as shall be specified in the Principal Value Conversion Notice pertaining to such Principal Value Conversion. 

        The
person in whose name the certificate is registered shall be deemed to be a stockholder of record on the Conversion Date; provided, however, that no surrender of a Security on any
date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or persons entitled to receive the shares of Common Stock upon such conversion as the
record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the person or persons entitled to receive such shares of Common Stock as the
record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; provided, further, that such conversion shall be at
the Conversion Price in effect on the date that such Security shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. Upon conversion of a
Security, such person shall no longer be a Holder of such Security. 

        No
payment or adjustment will be made for accrued interest (including contingent interest, if any), or Liquidated Damages, if any, on a converted Security or for dividends or
distributions on shares of Common Stock issued upon conversion of a Security (provided that the shares of Common Stock received upon conversion of Securities shall continue to accrue Liquidated
Damages, as applicable, in accordance with the Registration Rights Agreement and shall be entitled to receive, at the next interest payment date, any accrued and unpaid Liquidated Damages with respect
to the converted Securities), but if any Holder surrenders a Security for conversion between the record date for the payment of an installment of interest and the next interest payment date, then,
notwithstanding such conversion, the interest (including contingent interest, if any) or Liquidated Damages, if any, payable on such interest payment date shall be paid to the Holder of such Security
on such record date. In such event, such Security, when surrendered for conversion, must be accompanied by delivery of a check payable to the Conversion Agent in an amount equal to the interest
(including contingent interest, if any) or Liquidated Damages, if any, payable on such interest payment date on the portion so converted. If such payment does not accompany such Security, the Security
shall not be converted; provided, however, that no such check shall be required if such Security has been called for redemption on a Redemption Date within the period between and including such record
date and such interest payment date, or if 

39

 

such
Security is surrendered for conversion on the interest payment date. If the Company defaults in the payment of interest (including contingent interest, if any) or Liquidated Damages, if any,
payable on the interest payment date, the Conversion Agent shall repay such funds to the Holder. 

        If
a Holder converts more than one Security at the same time, the number of shares of Common Stock issuable upon the conversion shall be based on the aggregate principal amount of
Securities converted. 

        Upon
surrender of a Security that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new Security equal in principal amount
to the unconverted portion of the Security surrendered. 

        If
on the date of conversion of a Security pursuant to the 95% Trading Condition the Closing Price per share of Common Stock is greater than the Conversion Price, the Company shall pay
to the Holder of
such Security, in lieu of issuance of Conversion Shares based on the Conversion Price, cash in an amount equal to the principal amount of the Security surrendered for conversion as of such Conversion
Date (a "Principal Value Conversion"). The Company shall notify the surrendering Holder of any Security whose conversion is a Principal Value Conversion
and the Trustee (such notice being a "Principal Value Conversion Notice") of such Principal Value Conversion by the second Trading Day following the
Conversion Date for such conversion that the Company shall pay to such Holder the principal amount of such Security in cash. The Company shall pay the principal amount to be paid in cash in a
Principal Value Conversion on the third Trading Day after the Conversion Date for such conversion. 

        SECTION
10.03.    Adjustments Below Par Value. Before taking any action which would cause an adjustment decreasing the
Conversion Price so that the shares of Common Stock issuable upon conversion of the Securities would be issued for less than the par value of such Common Stock, the Company will take all corporate
action which may be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of such Common Stock at such adjusted Conversion Price. 

        SECTION
10.04.    Taxes on Conversion. If a Holder converts a Security, the Company shall pay any documentary, stamp or similar
issue or transfer tax due on the issue of shares of Common Stock upon such conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a
name other than the Holder's name. The Conversion Agent may refuse to deliver the certificates representing the Common Stock being issued in a name other than the Holder's name until the Conversion
Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder's name. Nothing herein shall preclude any tax withholding required
by law or regulations. 

40

   
        SECTION 10.05.    Company to Provide Stock. 

        The
Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve, out of its authorized but unissued Common Stock a sufficient number
of shares of Common Stock to permit the conversion of all outstanding Securities for shares of Common Stock. The shares of Common Stock or other securities issued upon conversion of Securities bearing
a Legend as provided in Section 2.06(f) shall bear a legend substantially in the following form: 

"THIS
SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND THIS SECURITY
MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER OF THIS
SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. 

THE
HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) TO A PERSON WHOM THE SELLER REASONABLY
BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II) PURSUANT TO AN EXEMPTION FROM REGISTRATION
UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (III) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (III) IN
ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF
THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE." 

        No
fractional shares of Common Stock shall be issued upon conversion of Securities. If more than one Security shall be surrendered for conversion at one time by the same holder, the
number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted
hereby) so surrendered. If any fractional share of Common Stock would be issuable upon the conversion of any Security or Securities, the Company shall make an adjustment thereof in cash at the current
market value thereof. For these purposes, the current market value of a share of Common Stock shall be the Closing Price
per share of Common Stock on the first Business Day immediately preceding the day on which the Securities (or specified portions thereof) are deemed to have been converted. 

        The
Company covenants that all shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares or treasury shares, shall be duly authorized, validly
issued, fully paid and non-assessable and shall be free from preemptive rights and free of any lien or adverse claim. 

        The
Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities, if any,
and will list or cause to have quoted such shares of Common Stock on each national securities exchange or in the over-the-counter market or such other market on which the Common Stock is then listed
or quoted. 

41

 

        SECTION
10.06.    Adjustment of Conversion Price. The conversion price (the "Conversion
Price") shall be that price set forth in paragraph 8 of the form of Security attached hereto as Exhibit A and shall be adjusted from time to time by the Company as follows: 

	(a)
	In
case the Company shall (i) pay a dividend or other distribution in shares of Common Stock or other Capital Stock to all or substantially all holders of Common Stock, (ii) subdivide
its outstanding Common Stock into a greater number of shares, (iii) combine its outstanding Common Stock into a smaller number of shares or (iv) reclassify its outstanding Common Stock, the Conversion
Price in effect immediately prior thereto shall be adjusted so that the Holder of any Security thereafter surrendered for conversion shall be entitled to receive the number of shares of Capital Stock
which it would have owned or have been entitled to receive had such Security been converted immediately prior to the happening of such event. An adjustment made pursuant to this subsection (a) shall
become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of subdivision, combination or
reclassification.

	(b)
	In
case the Company shall issue to all holders of its Common Stock, rights, warrants or options entitling such holders (for a period commencing no earlier than the record date
described below and expiring not more than 60 days after such record date) to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) at a price per share less
than the current market price per share of Common Stock (as determined in accordance with subsection (g) below) at the record date for the determination of stockholders entitled to receive such
rights, warrants or options, the Conversion Price in effect immediately prior thereto shall be adjusted so that the Conversion Price shall equal the price determined by multiplying the Conversion
Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding on such record date, plus the number of shares
which the aggregate subscription or purchase price for the total number of shares of Common Stock offered by the rights, warrants or options so issued (or the aggregate conversion price of the
convertible securities offered by such rights, warrants or options) would purchase at such current market price, and the denominator of which shall be the number of shares of Common Stock outstanding
on such record date plus the number of additional shares of Common Stock offered by such rights, warrants or options (or into which the convertible securities so offered by such rights, warrants or
options are convertible). Such adjustment shall be made successively whenever any such rights, warrants or options are issued, and shall become effective immediately after such record date. If at the
end of the period during which such rights, warrants or options are exercisable not all rights, warrants or options shall have been exercised, the adjusted Conversion Price shall be immediately
readjusted to what it would have been upon application of the foregoing adjustment substituting the number of additional shares of Common Stock actually issued (or the number of shares of Common Stock
issuable upon conversion of convertible securities actually issued) for the total number of shares of Common Stock offered (or the convertible securities offered).

	(c)
	In
case the Company shall distribute to all holders of its Common Stock any shares of Capital Stock of the Company (other than Common Stock) or evidences of its indebtedness, cash,
other securities or other assets, or shall distribute to all holders of its Common Stock, rights, warrants or options to subscribe for or purchase any of its securities (excluding: (i) rights,
options, warrants and other securities referred to in subsections (b) above or (d), (e) or (h) below; and (ii) those dividends, distributions, subdivisions and combinations referred to in subsection
(a) above); then in each such case the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the date
of such distribution or purchase by a fraction, the numerator of which shall be the current market price per share (as defined in subsection (g) below) of the 

42

 

Common
Stock on the record date mentioned below less the fair market value on such record date (as determined by the Board of Directors of the Company, whose determination shall be conclusive evidence
of such fair market value) of the portion of the Capital Stock or evidences of indebtedness, securities or assets so distributed or of such rights, warrants or options, in each case as applicable to
one share of Common Stock, and the denominator of which shall be the current market price per share (as defined in subsection (g) below) of the Common Stock on such record date. Such adjustment shall
become effective immediately after the record date for the determination of stockholders entitled to receive such distribution. 

	(d)
	In
the event the Company pays a dividend or makes a distribution to all holders of its Common Stock consisting of publicly-traded Capital Stock of any class or series, or similar
equity interests, of or relating to a Subsidiary or other business unit of the Company, the Conversion Price shall be adjusted, if at all, in accordance with the formula: 

	CP' =	    CP    	 	 
	 	(1+  F  )	 	 
	 	           M	 	 

	

	where:

	

	CP'
= the adjusted Conversion Price

	

	CP
= the current Conversion Price

	

	M
= the average of the Closing Prices of the Common Stock for the 10 Trading Days (as defined below) commencing on and including the fifth Trading Day after
the date on which "ex-dividend trading" commences for such dividend or distribution on the New York Stock Exchange or such other national exchange or market which such securities are then listed or
quoted.

	

	F
= the average of the Closing Prices of the securities distributed in respect of each share of Common Stock for which this subsection (d) applies for the
10 Trading Days commencing on and including the fifth Trading Day after the date on which "ex-dividend trading" commences for such dividend or distribution on the New York Stock Exchange or such other
national exchange or market which such securities are then listed or quoted.

	(e)
	In
case the Company shall declare a cash dividend or distribution to all the holders of Common Stock, the Conversion Price shall be decreased so that the Conversion Price shall equal
the price determined by multiplying the Conversion Price in effect immediately prior to the record date for such dividend or distribution by a fraction,

	(i)
	the
numerator of which shall be the average Closing Price of the Company's Common Stock for the three consecutive Trading Days ending on the date immediately preceding the record date
for such dividend or distribution (the "Pre-Dividend Sale Price"), minus the aggregate of the full amount of such cash dividend or distribution applicable to one share of Common Stock, and

	(ii)
	the
denominator of which shall be the Pre-Dividend Sale Price;

	

	such
adjustment to become effective immediately after the record date for such dividend or distribution; provided that no adjustment to the Conversion Price
or the ability of a Holder of a Security to convert will be made pursuant to this subsection (e) if the Company provides that Holders of Securities will participate in such cash dividend or
distribution on an as-converted basis without conversion.

	(f)
	In
case the Company or any of its Subsidiaries shall repurchase (including by way of tender or exchange offer, other than an odd lot tender offer) shares of Common Stock, and the fair
market value of the sum of (i) the aggregate consideration paid for such Common Stock, (ii) 

43

 

the
aggregate fair market value of cash dividends and distributions paid within the twelve (12) months preceding the date of purchase of such shares of Common Stock in respect of which no adjustment
pursuant to this Section 10.06 previously has been made, and (iii) the aggregate fair market value of any amounts previously paid for the repurchase of Common Stock of a type described in this
subsection (f) within the twelve (12) months preceding the date of purchase of such shares of Common Stock in respect of which no adjustment pursuant to this Section 10.06 previously has been made,
exceeds 10% of aggregate Market Capitalization on the date of, and after giving effect to, such repurchase, then the Conversion Price shall be adjusted so that the same shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to the date of such distribution or purchase by a fraction, the numerator of which shall be the current market price per
share (as defined in subsection (g) below) of the Common Stock on the date of such repurchase, less the quotient obtained by dividing the Aggregate Market Premium involved in such repurchase (as
defined hereinafter) by the difference between the number of shares of Common Stock outstanding before such repurchase and the number of shares of Common Stock the subject of such repurchase, and the
denominator of which shall be the current market price per share (as defined in subsection (g) below) of the Common Stock on the date of such repurchase. Such adjustment shall become effective
immediately after the date of such repurchase. For purposes of this subsection (f), the "Aggregate Market Premium" is the excess, if any, of the aggregate repurchase price paid for all such Common
Stock over the aggregate current market value per share (as defined in subsection (g) below) of all such repurchased stock, determined with respect to each share involved in each such repurchase as of
the date of repurchase with respect to such share. 

	(g)
	For
the purpose of any computation under subsections (b), (c) and (f) above, the current market price per share of Common Stock on any date shall be deemed to be the average of the
Closing Prices for 20 consecutive Trading Days commencing 30 Trading Days before the record date with respect to any distribution, issuance or other event requiring such computation. As used herein,
the term "Trading Days" with respect to Common Stock means (i) if the Common Stock is listed or admitted for trading on any national securities exchange, days on which such national securities
exchange is open for business or (ii) if the Common Stock is not so listed or admitted for trading, but is quoted on a system of automated dissemination of quotations of securities prices, days on
which trades may be made on such system.

	(h)
	If
the Company has implemented or implements a Stockholder Rights Plan (as defined below), the Company agrees that such Stockholder Rights Plan will provide that upon any conversion
of the Securities by any Holder prior to a Trigger Event (as defined below), the Holders shall receive the rights, warrants or options issued under such plan. Rights, warrants or options distributed
by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company's capital stock (either initially or under certain circumstances), which
rights, warrants or options, until the occurrence of a specified event or events (a "Trigger Event"):

	(i)
	are
deemed to be transferred with such shares of Common Stock,

	(ii)
	are
not exercisable, and

	(iii)
	are
also issued in respect of future issuances of Common Stock,

	

	(a
"Stockholder Rights Plan") shall not be deemed distributed for purposes of this Section 10.06 and no adjustment to the Conversion Price shall be required
to be made until the occurrence of the earliest Trigger Event. In addition, in the event of any Trigger Event with respect thereto, that shall have resulted in an adjustment to the Conversion Price
under this 

44

 

Section
10.06, (1) in the case of any such rights, warrants or options which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be
readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption
or repurchase price received by a holder of Common Stock with respect to such rights, warrants or options (assuming such holder had retained such rights, warrants or options), made to all holders of
Common Stock as of the date of such redemption or repurchase, and (2) in the case of any such rights, warrants or options all of which shall have expired without exercise by any holder thereof, the
Conversion Price shall be readjusted as if such issuance had not occurred. 

	

	In
any case in which this Section 10.06 shall require that an adjustment be made immediately following a record date established for purposes of this
Section 10.06, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate described in Section 10.10) issuing to the
holder of any Security converted after such record date the shares of Common Stock and other capital stock of the Company issuable upon such conversion over and above the shares of Common Stock and
other capital stock of the Company issuable upon such conversion only on the basis of the Conversion Price prior to adjustment; and, in lieu of the shares the issuance of which is so deferred, the
Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence of the right to receive such shares. 

        SECTION
10.07.    No Adjustment. No adjustment in the Conversion Price shall be required unless the adjustment would require an
increase or decrease of at least 1% in the Conversion Price as last
adjusted; provided, however, that any adjustments which by reason of this Section 10.07 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All
calculations under this Article X shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. 

        No
adjustment need be made for a transaction referred to in Section 10.06 if Holders are to participate in the transaction on a basis and with notice that the Board of Directors
determines to be fair and appropriate in light of the basis and notice on which holders of Common Stock participate in the transaction. Such participation by Holders may include participation upon
conversion; provided that an adjustment shall be made at such time as the Holders are no longer entitled to participate. 

        No
adjustment need be made for rights to purchase Common Stock or issuances of Common Stock pursuant to a Company plan for reinvestment of dividends or interest. 

        No
adjustment need be made for a change in the par value or a change to no par value of the Common Stock. 

        To
the extent that the Securities become convertible into cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. 

        SECTION
10.08.    Equivalent Adjustments. In the event that, as a result of an adjustment made pursuant to Section 10.06 above,
the Holder of any Security thereafter surrendered for conversion shall become entitled to receive any shares of Capital Stock of the Company other than shares of its Common Stock, thereafter the
Conversion Price of such other shares so receivable upon conversion of any Securities shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to
the provisions with respect to Common Stock contained in this Article X. 

        SECTION
10.09.    Adjustment for Tax Purposes. The Company shall be entitled to make such reductions in the Conversion Price, in
addition to those required by Section 10.06, as it in its discretion shall determine to be advisable in order that any stock dividends, subdivision of shares, distribution of rights to purchase stock
or securities, or a distribution or securities convertible into or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable. 

45

 

        SECTION
10.10.    Notice of Adjustment. Whenever the Conversion Price is adjusted, or Securityholders become entitled to other
securities or assets, the Company shall promptly mail to Securityholders a
notice of the adjustment and file with the Trustee an Officers' Certificate briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive
evidence of the correctness of such adjustment and the Trustee may conclusively assume that, unless and until such certificate is received by it, no such adjustment is required. 

        SECTION
10.11.    Notice of Certain Transactions. In case: 

	(a)
	the
Company shall declare a dividend (or any other distribution) on its Common Stock (other than in cash out of retained earnings); or

	(b)
	the
Company shall authorize the granting to the holders of its Common Stock of rights, warrants or options to subscribe for or purchase any share of any class or any other rights,
warrants or options; or

	(c)
	of
any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no
par value, or from no par value to par value, or of any consolidation, merger, or share exchange to which the Company is a party and for which approval of any stockholders of the Company is required,
or of the sale or transfer of all or substantially all of the assets of the Company; or

	(d)
	of
the voluntary or involuntary dissolution, liquidation or winding-up of the Company; 

the
Company shall cause to be filed with the Trustee and the Conversion Agent and to be mailed to each Holder of Securities at its address appearing on the list provided for in Section 2.05, as
promptly as possible but in any event at least ten days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution or rights, warrants or options, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or
rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, share exchange, sale, transfer, dissolution, liquidation or winding-up is expected to become
effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon
such reclassification, consolidation, merger, share exchange, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality
or validity of such dividend, distribution, reclassification, consolidation, merger, sale, share exchange, transfer, dissolution, liquidation or winding-up. 

        SECTION
10.12.    Effect of Reclassification, Consolidation,  Merger, Share Exchange or Sale on Conversion Privilege. 

        If
any of the following shall occur, namely: (i) any reclassification or change of outstanding shares of Common Stock (other than a change in par value, or from par value to no par
value, or from no par value to par value, or as a result of a subdivision or combination); (ii) any consolidation, combination, merger or share exchange to which the Company is a party (other than a
merger in which the Company is the continuing corporation and which does not result in any reclassification of, or change (other than a change in name, or par value, or from par value to no par value,
or from no par value to par value, or as a result of a subdivision or combination) in, outstanding shares of Common Stock); or (iii) any sale or conveyance of all or substantially all of the assets of
the Company, then the Company, or such successor or purchasing corporation, as the case may be, shall, as a condition precedent to such reclassification, change, consolidation, merger, share exchange,
sale or conveyance, execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then outstanding shall have the right to convert such Security into the kind
and amount of shares of Capital Stock and other securities and property (including cash) receivable upon such reclassification, change, 

46

 

consolidation,
merger, share exchange, sale or conveyance by a holder of the number of shares of Common Stock deliverable upon conversion of such Security immediately prior to such reclassification,
change, consolidation, merger, share exchange, sale or conveyance. Such supplemental indenture shall provide for adjustments of the Conversion Price which shall be as nearly equivalent as may be
practicable to the adjustments of the Conversion Price provided for in this Article X. If, in the case of any such consolidation, merger, share exchange, sale or conveyance, the stock or other
securities and property (including cash) receivable thereupon by a holder of Common Stock includes shares of Capital Stock or other securities and property of a corporation other than the successor or
purchasing corporation, as the case may be, in such consolidation, merger, share exchange, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and
shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors of the Company shall reasonably consider necessary by reason of the
foregoing. The provision of this Section 10.12 shall similarly apply to successive consolidations, mergers, share exchanges, sales or conveyances. Notwithstanding the foregoing, a distribution by the
Company to all or substantially all holders of its Common Stock for which an adjustment to the Conversion Price or provision for conversion of the Securities may be made pursuant to Section 10.06
shall not be deemed to be a sale or conveyance of all or substantially all of the assets of the Company for purposes of this Section 10.12. 

        In
the event the Company shall execute a supplemental indenture pursuant to this Section 10.12, the Company shall promptly file with the Trustee an Opinion of Counsel stating that such
supplemental indenture is authorized or permitted by this Indenture and an Officers' Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or securities or property
(including cash) receivable by Holders of the Securities upon the conversion of their Securities after any such reclassification, change, consolidation, merger, share exchange, sale or conveyance, any
adjustment to be made with respect thereto and that all conditions precedent have been complied with. 

        SECTION
10.13.    Trustee's Disclaimer. 

        The
Trustee has no duty to determine when an adjustment under this Article X should be made, how it should be made or what such adjustment should be made, but may accept as conclusive
evidence of the correctness of any such adjustment, and shall be protected in relying upon, the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee
pursuant to Section 10.10. The Trustee shall not be accountable for and makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the
Trustee shall not be responsible for the Company's failure to comply with any provisions of this Article X. Each Conversion Agent (other than the Company or an Affiliate of the Company) shall have the
same protection under this Section 10.13 as the Trustee. 

        The
Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 10.12, but may
accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee
pursuant to Section 10.12. 

        SECTION
10.14.    Voluntary Reduction. 

        The
Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least 20 Trading Days or such longer period as may be required by
law and if the reduction is irrevocable during the period; provided that in no event may the Conversion Price be less than the par value of a share of Common Stock. 

        SECTION
10.15.    Simultaneous Adjustments. 

        In
the event that this Article X requires adjustments to the Conversion Price under more than one of Sections 10.06(c), (d) and (e), and the record dates for the distributions giving
rise to such adjustments shall occur on the same date, then such adjustments shall be made by applying, first, the 

47

 

provisions
of Section 10.06(d) or (e), as applicable, and, second, the provisions of Section 10.06(c). If more than one event requiring adjustment pursuant to Section 10.06 shall occur before
completing the determination of the Conversion Price for the first event requiring such adjustment, then the Board of Directors (whose determination shall, if made in good faith, be conclusive) shall
make such adjustments to the Conversion Price (and the calculation thereof) after giving effect to all such events as shall preserve for Securityholders the Conversion Price protection provided in
Section 10.06. 

ARTICLE XI

SUBORDINATION  

        SECTION 11.01.    Terms and Conditions of Subordination. The Company, for itself and its successors, and
each Holder, by its acceptance of Securities, agree that the payment of the principal of or interest on or any other amounts due on the Securities is subordinated in right of payment, in cash or cash
equivalent, to the extent and in the manner stated in this Article XI, to the prior payment in full when due, by acceleration or otherwise, of all existing and future Senior Indebtedness of the
Company. The Securities shall rank pari passu with, or senior in right of payment to, Indebtedness of the Company (other than Senior Indebtedness)
whether outstanding on the date of this Indenture or hereafter created, incurred, issued or guaranteed by the Company. 

        The
Securities shall be subordinate in right of payment to all existing and future Senior Indebtedness of the Company. The payment of the principal of, interest on or any other amounts
due on the Securities is subordinated in right of payment to the prior payment in full of all existing and future Senior Indebtedness when due, by acceleration or otherwise. No payment on account of
principal of, redemption of, interest on or any other amounts due on the Securities, and no redemption, purchase or other acquisition of the Securities may be made, including a purchase on a Purchase
Date or Change in Control Purchase Date pursuant to Article III hereof, if: 

        (a)   a
default in the payment of any Designated Senior Indebtedness occurs and is continuing (for purposes of this Article XI, "Payment
Default"); or 

        (b)   any
other default on any Designated Senior Indebtedness occurs and is continuing that permits the holders of Designated Senior Indebtedness to accelerate its maturity,
and the Trustee receives a notice of such default (a "Payment Blockage Notice") from the Company or from any holder of Designated Senior Indebtedness or
such holder's representative (a "Nonpayment Default"), but only for the period (the "Payment Blockage
Period") commencing on the date of receipt by the Trustee of the Payment Blockage Notice and ending (unless earlier terminated by notice given to the Trustee by the holders of
such Designated Senior Indebtedness) (a) in the case of a Payment Default, upon the date on which such Payment Default is cured or waived or ceases to exist, and (b) in the case of a Nonpayment
Default, upon the earlier of the date on which such Nonpayment Default is cured or waived or ceases to exist or 179 days after the date on which the Payment Blockage Notice is received. Upon
termination of the Payment Blockage Period, unless the holders of any Designated Senior Indebtedness have accelerated the maturity of such Designated Senior Indebtedness and such Designated Senior
Indebtedness remains unpaid, payments on account of principal of or interest on the Securities (other than, subject to Section 11.02 hereof, amounts due and payable by reason of the acceleration of
the maturity of the Securities) and redemptions, purchases or other acquisitions shall be made by or on behalf of the Company. 

48

   
        Notwithstanding the foregoing, only one Payment Blockage Notice with respect to a Nonpayment Default may be given and no new Payment Blockage Period may be commenced for a default unless
at least 365 consecutive days have elapsed since the effectiveness of the immediately prior Payment Blockage Notice and all scheduled payments of the Securities that have come due have been paid in
full in cash. No Nonpayment Default that existed or was continuing on the date of delivery of any Payment Blockage Notice shall be the basis for a subsequent Payment Blockage notice. For the avoidance
of doubt, any Payment Default or Nonpayment Default that occurs after the date of delivery of a Payment Blockage Notice may be the basis for a subsequent Payment Blockage Notice, if such Payment
Default or Nonpayment Default exists or is continuing on the date of delivery of the subsequent Payment Blockage Notice. 

        If
the Trustee or any Holder of Securities receives any payment or distribution of the Company's assets of any kind in contravention of any of the terms hereof, whether in cash, property
or securities, in respect of the Securities before all Senior Indebtedness is paid in full in cash or cash equivalents, then the payment or distribution will be held by the recipient in trust for the
benefit of holders of Senior Indebtedness, and will be immediately paid over or delivered to the holders of Senior Indebtedness or their representative or representatives to the extent necessary to
make payment in full of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution, or provision therefor, to or for the holders of Senior Indebtedness.
Any Holder of Securities will notify the Trustee of receipt of any such payment or distribution. 

        SECTION
11.02.    Distribution on Acceleration of Securities, Dissolution and
Reorganization. 

        (a)   If
the Securities are declared due and payable because of the occurrence of an Event of Default, the Company or the Trustee shall give prompt written notice to the
holders of all Senior Indebtedness or to the trustee(s) for such Senior Indebtedness of such acceleration. 

        (b)   Upon
(i) any acceleration of the principal amount due on the Securities because of an Event of Default or (ii) any distribution of assets of the Company upon any
dissolution, winding up, liquidation or reorganization of the Company (whether in bankruptcy, insolvency or receivership proceedings or upon an assignment for the benefit of creditors or any other
dissolution, winding up, liquidation or reorganization of the Company): 

          (i)  the
holders of all Senior Indebtedness shall first be entitled to receive payment in full, in cash or cash equivalents, of the principal thereof, the interest thereon
and any other amounts then due thereon before the Holders are entitled to receive payment on account of the principal of or interest on
(including contingent interest, if any) and Liquidated Damages, if any, or any other amounts due on the Securities; 

         (ii)  any
payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders or the Trustee would be
entitled except for the provisions of this Article XI, shall be paid by the liquidating trustee or agent or other person making such a payment or distribution, directly to the holders of Senior
Indebtedness (or their representatives(s) or trustee(s) acting on their behalf), ratably according to the aggregate amounts remaining unpaid on account of the principal of or interest on and other
amounts due on the Senior Indebtedness held or represented by each, to the extent necessary to make payment in full, in cash or cash equivalent, of all Senior Indebtedness remaining unpaid, after
giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness, provided, however, the Trustee's rights to compensation, reimbursement of expenses and
indemnification under Sections 6.10 and 7.07 are not subordinated; 

        (iii)  in
the event that, notwithstanding the foregoing, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or
securities, shall be received by the Trustee or the Holders before all Senior Indebtedness is paid in full, such payment or 

49

 

distribution
shall be held in trust for the benefit of, and be paid over to upon request by a holder of the Senior Indebtedness, the holders of the Senior Indebtedness remaining unpaid (or their
representatives) or trustee(s) acting on their behalf, ratably as aforesaid, for application to the payment of such Senior Indebtedness until all such Senior Indebtedness shall have been paid in full,
after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness; and 

        (iv)  to
the extent any payment of Senior Indebtedness (whether by or on behalf of the Company, as proceeds of security or enforcement of any right of setoff or otherwise) is
declared to be fraudulent or preferential or otherwise set aside or required to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or other similar person under any bankruptcy,
insolvency, receivership, fraudulent conveyance or similar law, then if such payment is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidation trustee, agent or other similar
person, the Senior Indebtedness or part thereof originally intended to be satisfied shall be deemed to be reinstated and outstanding as if such payment had not occurred. 

        Subject
to the payment in full, in cash or cash equivalent, of all Senior Indebtedness, the Holders shall be subrogated to the rights of the holders of Senior Indebtedness to receive
payments or distributions of cash, property or securities of the Company applicable to the Senior Indebtedness until the principal of and interest (including contingent interest, if any) and
Liquidated Damages, if any, on the Securities shall be paid in full and, for purposes of such subrogation, no such payments or distributions to the holders of Senior Indebtedness of cash, property or
securities which otherwise would have been payable or distributable to Holders shall, as between the Company, its creditors other than the holders of Senior Indebtedness, and the Holders, be deemed to
be a payment by the Company to or on account of the Senior Indebtedness, it being understood that the provisions of this Article XI are and are
intended solely for the purpose of defining the relative rights of the Holders, on the one hand, and the holders of Senior Indebtedness, on the other hand. 

        Nothing
contained in this Article XI or elsewhere in this Indenture or in the Securities is intended to or shall (i) impair, as between the Company and its creditors other than the
holders of Senior Indebtedness, the obligation of the Company, which is absolute and unconditional, to pay to the Holders the principal of and interest (including contingent interest, if any) and
Liquidated Damages, if any, on the Securities as and when the same shall become due and payable in accordance with the terms of the Securities or (ii) affect the relative rights of the Holders and
creditors of the Company other than holders of Senior Indebtedness or, as between the Company and the Trustee, the obligations of the Company to the Trustee, or (iii) prevent the Trustee or the
Holders from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article XI of the holders of Senior Indebtedness
in respect of cash, property and securities of the Company received upon the exercise of any such remedy. 

        Upon
distribution of assets of the Company referred to in this Article XI, the Trustee and the Holders shall be entitled to rely upon a certificate of the liquidating trustee or agent or
other person making any distribution to the Trustee or to the Holders for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Indebtedness
and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XI. The
Trustee, however, shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness. Nothing contained in this Article XI or elsewhere in this Indenture or in any of the Securities
shall prevent the good faith application by the Trustee of any moneys which were deposited with it hereunder, prior to its receipt of written notice of facts which would prohibit such application, for
the purpose of the payment of or on account of the principal of or interest (including contingent interest, if any) and Liquidated Damages, if any, on, the Securities unless, prior to the date on
which such application is 

50

 

made
by the Trustee, the Trustee shall be charged with notice under Section 11.02(d) hereof of the facts which would prohibit the making of such application. 

        (c)   The
provisions of this Article XI shall not be applicable to any cash, properties or securities received by the Trustee or by any Holder when received as a holder of
Senior Indebtedness and nothing in the Indenture or this Indenture shall deprive the Trustee or such Holder of any of its rights as such holder. 

        (d)   The
Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the making of any payment of money to or by the Trustee
in respect of the Securities pursuant to the provisions of this Article XI. The Trustee shall be entitled to assume that no such fact exists unless the Company or any holder of Senior Indebtedness or
any trustee therefor has given such notice to the Trustee. Notwithstanding the provisions of this Article XI or any other provisions of this Indenture, the Trustee shall not be charged with knowledge
of the existence of any fact which would prohibit the making of any payment of monies to or by the Trustee in respect of the Securities pursuant to the provisions in this Article XI, unless, and until
three Business Days after, the Trustee shall have received written notice thereof from the Company or any holder or holders of Senior Indebtedness or from any trustee therefor; and, prior to the
receipt of any such written notice, the Trustee shall be entitled in all respects conclusively to assume that no such facts exist; provided that if on a date not less than three Business Days
immediately preceding the date upon which by the terms hereof any such monies may become payable for any purpose (including, without limitation, the principal of or interest (including contingent
interest, if any) and Liquidated Damages, if any, on any Security), the Trustee shall not have received with respect to such monies the notice provided for in this Section 11.02(d), then anything
herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such monies and to apply the same to the purpose for which they were received, and shall
not be affected by any notice to the contrary which may be received by it on or after such prior date. 

        The
Trustee shall be entitled to rely on the delivery to it of a written notice by a person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such
holder) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee on behalf of any such holder or holders). In the event that the Trustee determines in good faith
that further evidence is required with respect to the right of any person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article XI, the Trustee may
request such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such person, the extent to which such person is entitled to
participate in such payment or distribution and any other facts pertinent to the rights of such person under this Article XI, and, if such evidence is not furnished, the Trustee may defer any payment
to such person pending judicial determination as to the right of such person to receive such payment; nor shall the Trustee be charged with knowledge of the curing or waiving of any default of the
character specified in Section 11.01 or that any event or any condition preventing any payment in respect of the Securities shall have ceased to exist, unless and until the Trustee shall have received
an Officers' Certificate to such effect. 

        (e)   The
provisions of this Section 11.02 applicable to the Trustee shall also apply to any Paying Agent for the Company. 

        (f)    Each
Holder of a Security, by its acceptance thereof, authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to
effectuate the subordination provided in this Article XI and appoints the Trustee its attorney-in-fact for any and all such purposes, including, in the event of any dissolution, winding up or
liquidation or reorganization under any applicable bankruptcy law of the Company (whether in bankruptcy, insolvency or receivership proceedings or otherwise), the timely filing of a claim for the
unpaid balance of such Holder's Securities in the form required in such proceedings and the causing of such claim to be approved. If the Trustee does not file 

51

 

a
claim or proof of debt in the form required in such proceedings prior to 30 days before the expiration of the time to file such claims or proofs, then any holder or holders of Senior Indebtedness or
their representative or representatives shall have the right to demand, sue for, collect, receive and receipt for the payments and distributions in respect of the Securities which are required to be
paid or delivered to the holders of Senior Indebtedness as provided in this Article XI and to file and prove all claims therefor and to take all such other action in the name of the holders or
otherwise, as such holders of Senior Indebtedness or representative thereof may determine to be necessary or appropriate for the enforcement of the provisions of this Article XI.

[FORM OF REVERSE SIDE OF NOTE]

FIRST HORIZON PHARMACEUTICAL CORPORATION  

        1.75% Contingent Convertible Senior Subordinated Notes Due 2024 

        1.     Interest. 

        This
Security shall accrue interest at an initial rate of 1.75% per annum. The Company promises to pay interest on the Securities in cash semiannually on each March 8 and September 8,
commencing September 8, 2004, to Holders of record on the immediately preceding February 22 and August 24, respectively, whether or not such day is a Business Day. Interest on the Securities will
accrue from the most recent date to which interest has been paid, or if no interest has been paid, from March 8, 2004, until the Principal Amount is paid or duly made available for payment. The
Company will pay interest on any overdue Principal Amount at the interest rate borne by the Securities at the time such interest on the overdue Principal Amount accrues, compounded semiannually, and
it shall pay interest on overdue installments of interest and Liquidated Damages, if any (without regard to any applicable grace period), at the same interest rate compounded semiannually. Interest
(including contingent interest, if any) on the Securities will be computed on the basis of a 360-day year comprised of twelve 30-day months. 

        The
Company shall pay contingent interest to the Holders during any six-month period (a "Contingent Interest Period") from March 8 to, but
excluding, September 8 and from September 8 to, but excluding, March 8, with the initial six-month period commencing March 8, 2007, if the average Security Trading Price for the five Trading Day
period ending on the third Trading Day immediately preceding the first day of the applicable Contingent Interest Period equals $1,200 or more. The amount of contingent interest payable per $1,000
principal amount of Securities in respect of any Contingent Interest Period shall equal 0.5% per annum. The Company will pay contingent interest, if any, in the same manner as it will pay interest as
described above. 

        2.     Method
of Payment. 

        The
Company will pay interest (including contingent interest, if any) and Liquidated Damages, if any, on this Security (except defaulted interest) to the Person who is the registered
Holder of this Security at the close of business on February 22 or August 24, as the case may be, next preceding the related interest payment date. Subject to the terms and conditions of the
Indenture, the Company will make payments in respect of the Redemption Price, Purchase Price, Change in Control Purchase Price and the Principal Amount at Stated Maturity, as the case may be, to the
Holder who surrenders a Security to a Paying Agent to collect such payments in respect of the Security. The Company will pay cash amounts in money of the United States that at the time of payment is
legal tender for payment of
public and private debts. However, the Company may pay interest (including contingent interest, if any), Liquidated Damages, if any, the Redemption Price, Purchase Price, Change in Control Purchase
Price and the Principal Amount at Stated Maturity, as the case may be, by check or wire payable in such money; provided, however, that a Holder holding Securities with an aggregate Principal Amount in
excess of $1,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder. The Company may mail an interest check to the Holder's registered address. 

        Notwithstanding
the foregoing, so long as this Security is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately
available funds to the account of the Depositary or its nominee. 

        3.     Paying
Agent, Conversion Agent and Registrar. 

        Initially,
Deutsche Bank Trust Company Americas (the "Trustee") will act as Paying Agent, Conversion Agent and Registrar. The Company may
appoint and change any Paying Agent, Conversion Agent or Registrar without notice, other than notice to the Trustee; provided that the Company will 

A-1-4

 

maintain
at least one Paying Agent in the State of New York, City of New York, Borough of Manhattan, which shall initially be an office or agency of the Trustee. The Company or any of its Subsidiaries
or any of their Affiliates may act as Paying Agent, Conversion Agent or Registrar. 

        4.     Indenture;
Ranking. 

        The
Company issued the Securities under an Indenture dated as of March 8, 2004 (the "Indenture"), between the Company and the Trustee. The
terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as in effect from time to time (the
"TIA"). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such
terms, and Securityholders are referred to the Indenture and the TIA for a statement of those terms. 

        The
Securities are limited to $150,000,000 aggregate Principal Amount (which shall include the Initial Purchasers' option to purchase up to $25,000,000 of additional Securities) (subject
to Section 2.07 of the Indenture). The Securities are the Company's unsecured obligations and will be subordinated in right of payment to all of the Company's existing and future Senior Indebtedness
and effectively subordinated to all existing and future Indebtedness and other liabilities of the Subsidiaries. The Securities will rank pari passu
with, or senior, in right of payment to the Company's existing and future Indebtedness (other than Senior Indebtedness). The Indenture does not limit other indebtedness of the Company, secured or
unsecured. 

        5.     Redemption
at the Option of the Company. 

        No
sinking fund is provided for the Securities. The Securities are not redeemable prior to March 13, 2007. Beginning on March 13, 2007 and during the periods thereafter to maturity, the
Securities are redeemable as a whole, or from time to time in part, in any integral multiple of $1,000, at any time at the option of the Company at a Redemption Price equal to 100% of the Principal
Amount, together with accrued and unpaid interest (including contingent interest, if any) and Liquidated Damages, if any, thereon, up to but not including the Redemption Date; provided that, if the
Redemption Date is on or after an interest record date but on or prior to the related interest payment date, interest and Liquidated Damages, if any, will be payable to the Holders in whose names the
Securities are registered at the close of business on the relevant record date. 

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

        Subject
to the terms and conditions of the Indenture, the Company shall become obligated to purchase, at the option of the Holder, all or any portion of the Securities held by such
Holder, in any integral multiple of $1,000, on March 8, 2009, 2014 and 2019 (each, a "Purchase Date") at a purchase price per Security equal to 100% of
the aggregate Principal Amount of the Security (the "Purchase Price"), together with accrued and unpaid interest (including contingent interest, if any)
and Liquidated Damages, if any, thereon, up to but not including the Purchase Date (provided that, if the Purchase Date is on or after an interest record date but on or prior to the related interest
payment date, accrued and unpaid interest (including contingent interest, if any) and Liquidated Damages, if any, will be payable to the Holders in whose names the Securities are registered at the
close of business on the relevant record date) upon delivery of a Purchase Notice containing the information set forth in the Indenture, together with the Securities subject thereto, at any time from
the opening of business on the date that is 20 Business Days prior to such Purchase Date until the close of business on the Business Day prior to such Purchase Date, and upon delivery of the
Securities to the Paying Agent by the Holder as set forth in the Indenture. 

        At
the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase the Securities held by such Holder after the
occurrence of a Change in Control of the Company for a Change in Control Purchase Price equal to 100% of the Principal Amount thereof plus accrued and unpaid interest (including contingent interest,
if any) and 

A-1-5

 

Liquidated
Damages, if any, thereon, up to but not including the Change in Control Purchase Date which Change in Control Purchase Price shall be paid in cash. Holders have the right to withdraw any
Purchase Notice or Change in Control Purchase Notice, as the case may be, by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture. 

        If
cash sufficient to pay the Purchase Price or Change in Control Purchase Price, as the case may be, and accrued and unpaid interest (including contingent interest, if any) and
Liquidated Damages, if any, of all Securities or portions thereof to be purchased as of the Purchase Date or the Change in Control Purchase Date, as the case may be, is deposited with the Paying Agent
on the Business Day following the Purchase Date or the Change in Control Purchase Date, interest (including contingent interest, if any) and Liquidated Damages, if any, cease to accrue on such
Securities (or portions thereof) immediately after such Purchase Date or Change in Control Purchase Date, and the Holder thereof shall have no other rights as such other than the right to receive the
Purchase Price or Change in Control Purchase Price, as the case may be, upon surrender of such Security. 

        7.     Notice
of Redemption. 

        Notice
of redemption pursuant to paragraph 5 of this Security will be mailed at least 20 days but not more than 60 days before the Redemption Date to each Holder of Securities to be
redeemed at the Holder's registered address. If money sufficient to pay the Redemption Price of all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying
Agent prior to or on the Redemption Date, immediately after such Redemption Date interest (including contingent interest, if any) and Liquidated Damages, if any, cease to accrue on such Securities or
portions thereof. Securities in denominations larger than $1,000 of Principal Amount may be redeemed in part but only in integral multiples of $1,000 of Principal Amount. 

        8.     Conversion.

        Subject
to the provisions of Article X of the Indenture, a Holder of a Security may convert such Security into shares of Common Stock of the Company if any of the conditions specified in
paragraphs (a) through (e) of Section 10.01 of the Indenture is satisfied. The initial conversion price is $22.15 per share, subject to adjustment under certain circumstances as described in Article X
of the Indenture (the "Conversion Price"). The number of shares issuable upon conversion of a Security is determined by dividing the principal amount
converted by the Conversion Price in effect on the Conversion Date. In the event of a conversion of a Security in a Principal Value Conversion, the Company shall deliver cash to the Holder of the
Security surrendered for such conversion as provided in Section 10.02 of the Indenture. Upon conversion, no adjustment for interest (including contingent interest, if any), or dividends will be made.
No fractional shares required to be issued upon conversion; in lieu thereof, an amount will be paid in cash based upon the current market price (as defined in the Indenture) of the Common Stock on the
last Trading Day prior to the date of conversion. 

        To
convert a Security, a Holder must (a) complete and sign the conversion notice set forth below and deliver such notice to the Conversion Agent, (b) surrender the Security to the
Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by the Registrar or the Conversion Agent, (d) pay any transfer or similar tax, if required and (e) if the
Security is held in book-entry form, complete and deliver to the Depositary appropriate instructions pursuant to the Depositary's book-entry conversion programs. If a Holder surrenders a Security for
conversion between the record date for the payment of an installment of interest and the next interest payment date, the Security must be accompanied by payment of an amount equal to the interest
(including contingent interest, if any) and Liquidated Damages, if any, payable on such interest payment date on the principal amount of the Security or portion thereof then converted; provided,
however, that no such payment shall be required if such Security has been called for redemption on a Redemption Date within the period between and including such record date and such interest payment
date, or if such 

A-1-6

 

Security
is surrendered for conversion on the interest payment date. A Holder may convert a portion of a Security equal to $1,000 or any integral multiple thereof. 

        A
Security in respect of which a Holder has delivered a Purchase Notice or a Change of Control Repurchase Notice exercising the option of such Holder to require the Company to repurchase
such Security as provided in Section 3.08 or Section 3.09, respectively, of the Indenture may be converted only if such notice of exercise is withdrawn as provided above and in accordance with the
terms of the Indenture. 

        9.     Denominations;
Transfer; Exchange. 

        The
Securities are in fully registered form, without coupons, in denominations of $1,000 of Principal Amount and integral multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required
by law or permitted by the Indenture. The Registrar need not transfer or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or any Securities in respect of which a Purchase Notice or a Change in Control Purchase Notice has been given and not withdrawn (except, in the case of a Security to be
purchased in part, the portion of the Security not to be purchased) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 

        10.   Persons
Deemed Owners. 

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

        11.   Unclaimed
Money or Securities. 

        The
Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that
remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, Holders entitled to the money or securities must look to the Company, for payment as general
creditors unless an applicable abandoned property law designates another person. 

        12.   Amendment;
Waiver. 

        Subject
to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in aggregate
Principal Amount of the Securities at the time outstanding and (ii) certain Defaults may be waived with the written consent of the Holders of a majority in aggregate Principal Amount of the Securities
at the time outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee may amend the Indenture or the Securities so
long as such changes, other than those in clause (ii), do not adversely affect the interest of Securityholders (i) to cure any ambiguity, omission, defect or inconsistency, (ii) to comply with Article
V or Section 10.01(e) or Section 10.12 of the Indenture, (iii) to evidence and provide for the acceptance of appointment under the Indenture by a successor Trustee, or (iv) to comply with any
requirement of the SEC in connection with the qualification of the Indenture under the TIA. 

        13.   Defaults
and Remedies. 

        Under
the Indenture, Events of Default include, in summary form, (i) default in the payment of any interest (including contingent interest, if any) or Liquidated Damages, if any, on any
Securities and such default continues for 10 Business Days, whether or not prohibited by the subordination provisions of the Indenture; (ii) default in payment of the Principal Amount, Redemption
Price, Purchase Price or Change in Control Purchase Price, as the case may be, in respect of the Securities when the same 

A-1-7

 

becomes
due and payable, whether or not prohibited by the subordination provisions of the Indenture; (iii) failure by the Company in the performance, or breach, of any of the Company's other covenants
in this Security or the Indenture which are not remedied within 30 days of receipt of notice thereof; (iv) defaults by the Company or a Subsidiary in the payment when due of Indebtedness in excess of
$1,000,000; (v) the Company or a Subsidiary fails to pay when due any final, non-appealable judgment (other than any judgment as to which a reputable insurance company has accepted full liability)
aggregating in excess of $1,000,000, which judgments are not stayed, bonded or discharged within 60 days of their entry; (vi) failure by the Company to issue Common Stock upon conversion of Securities
by a Holder in accordance with the provisions of the Indenture; (vii) failure by the Company to give notice to Holders of their right to require the Company to repurchase Securities upon a Change in
Control or fails to make a payment to purchase Securities tendered following a Change in Control, whether or not prohibited by the subordination provisions of the Indenture; (viii) if a material
portion of the Company's or a Subsidiary's assets, which assets represent a material portion of the assets of the Company and its Subsidiaries as a whole, is attached, seized or subjected to a write
or distress warrant or is levied upon, or come within the possession of any receiver, trustee, custodian or assignee for the benefit of creditors and the same is not terminated or dismissed within 30
days thereafter; and (ix) certain events of bankruptcy or insolvency. 

        Securityholders
may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives
reasonable indemnity or security. Subject to certain limitations, Holders of a majority in aggregate Principal Amount of the Securities at the time outstanding may direct the Trustee in its exercise
of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of amounts specified in clause (i) or (ii) above) if it determines
that withholding notice is in their interests. 

        14.   Trustee
Dealings with the Company. 

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

        15.   No
Recourse Against Others. 

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

        16.   Authentication.

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

2.    Shelf Registration. 

        (a)   Shelf Registration. The Company shall file with the SEC a Registration Statement for an offering to be made on a
continuous basis pursuant to Rule 415 covering all of the Registrable Securities (the "Initial Shelf Registration") on or prior to the Filing
Date. 

        The
Initial Shelf Registration shall be on Form S-3 or another appropriate form permitting registration of such Registrable Securities for resale by Holders in the
manner or manners designated by them (excluding Underwritten Offerings). The Company shall not permit any securities other than the Registrable Securities to be included in the Initial Shelf
Registration or any Subsequent Shelf Registration (as defined below). 

        The
Company shall use all reasonable efforts to cause the Initial Shelf Registration to be declared effective under the Securities Act on or prior to the Effectiveness Date and to keep
such Initial Shelf Registration continuously effective under the Securities Act until the date that is two years after the Closing Date (such period, as it may be shortened pursuant to clauses (i),
(ii) or (iii) immediately following, the "Effectiveness Period"), or such shorter period ending when (i) all of the Registrable
Securities covered by the Initial Shelf Registration have been sold in the manner set forth and as contemplated in the Initial Shelf Registration, (ii) the date on which all the Registrable
Securities 

3

 

(x) held
by Persons who are not affiliates of the Company may be resold pursuant to Rule 144(k) under the Securities Act or (y) cease to be outstanding, or (iii) a
Subsequent Shelf Registration covering all of the Registrable Securities has been declared effective under the Securities Act. 

        (b)   Subsequent Shelf Registrations. If the Initial Shelf Registration or any Subsequent Shelf Registration (as defined below)
ceases to be effective for any reason at any time during the Effectiveness Period (other than because of the sale of all of the Registrable Securities registered thereunder), the Company shall use all
reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within 45 days of such cessation of effectiveness amend the Initial
Shelf Registration in a manner to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional "shelf" Registration Statement pursuant to Rule 415 covering all
of the Registrable Securities (a "Subsequent Shelf Registration"). If a Subsequent Shelf Registration is filed, the Company shall use all reasonable
efforts to cause the Subsequent Shelf Registration to be declared effective under the Securities Act as soon as practicable after such filing and to keep such Registration Statement continuously
effective for a period equal to the number of days in the Effectiveness Period less the aggregate number of days during which the Initial Shelf Registration or any Subsequent Shelf Registration was
previously continuously effective. As used herein, the term "Shelf Registration" means the Initial Shelf Registration and any Subsequent Shelf
Registration and the term "Shelf Registration Statement" means any Registration Statement filed in connection with a Shelf Registration. 

        (c)   Supplements and Amendments. The Company shall promptly supplement and amend the Shelf Registration if required by the
rules, regulations or instructions applicable to the registration form used for such Shelf Registration, if required by the Securities Act. 

        (d)   Notice and Questionnaire. Each Holder agrees that if such Holder wishes to sell Registrable Securities pursuant to a
Shelf Registration Statement and related Prospectus, it will do so only in accordance with this Section 2(d) and Section 4 hereof. Each Holder wishing to sell Registrable Securities
pursuant to a Shelf Registration Statement and related Prospectus agrees to deliver a Notice and Questionnaire to the Company at least five (5) Business Days prior to any intended distribution
of Registrable Securities under the Shelf Registration Statement. From and after the date the Initial Shelf Registration Statement is declared effective, the Company shall, as promptly as practicable
after the date a Notice and Questionnaire is delivered, and in any event upon the later of (x) five (5) Business Days after such date or (y) five (5) Business Days after
the expiration of any Deferral Period in effect when the Notice and Questionnaire is delivered or put into effect within five (5) Business Days of such delivery date: 

          (i)  if
required by applicable law, file with the SEC a post-effective amendment to the Shelf Registration Statement or prepare and, if required by applicable
law, file a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that the Holder delivering
such Notice and Questionnaire is named as a selling securityholder in the Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus
to purchasers of the Registrable Securities in accordance with applicable law and, if the Company shall file a post-effective amendment to the Shelf Registration Statement, use all
reasonable efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is practicable, but in any event by the date (the
"Amendment Effectiveness Deadline Date") that is forty-five (45) days after the date such post-effective amendment is
required by this clause to be filed; 

         (ii)  provide
such Holder copies of any documents filed pursuant to Section 2(d)(i); and 

        (iii)  notify
such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to
Section 2(d)(i); provided that if such Notice 

4

 

and
Questionnaire is delivered during a Deferral Period (as defined in Section 3(b)), the Company shall so inform the Holder delivering such Notice and Questionnaire and shall take the actions
set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral Period. Notwithstanding anything contained herein to the contrary, (i) the Company shall be under no
obligation to name any Holder that has not delivered a Notice and Questionnaire to the Company in accordance with this Section 2(d) and (ii) the Amendment Effectiveness Deadline Date
shall be extended by up to ten (10) Business Days from the expiration of a Deferral Period (and the Company shall incur no obligation to pay Liquidated Damages during such extension) if such
Deferral Period shall be in effect on the Amendment Effectiveness Deadline Date. 

3.    Liquidated Damages. 

        (a)   The
Company and the Initial Purchasers agree that the Holders of Registrable Securities will suffer damages if the Company fails to fulfill certain of its obligations
under Section 2 hereof or otherwise permits certain circumstances to exist and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Company
agrees to pay liquidated damages on the Registrable Securities ("Liquidated Damages") under the circumstances and to the extent set forth below (each of
which shall be given independent effect; each a "Registration Default"): 

          (i)  if
the Initial Shelf Registration is not filed on or prior to the Filing Date, then commencing on the day after the Filing Date, Liquidated Damages shall accrue on the
Registrable Securities at a rate of 0.50% per annum on the Amount of Registrable Securities; 

         (ii)  if
the Initial Shelf Registration or Subsequent Shelf Registration is not declared effective by the SEC on or prior to the Effectiveness Date, then commencing on the
day after the Effectiveness Date, Liquidated Damages shall accrue on the Registrable Securities at a rate of 0.50% per annum on the Amount of Registrable Securities; and 

        (iii)  if
a Shelf Registration has been declared effective and such Shelf Registration ceases to be effective at any time during the Effectiveness Period (other than as
permitted under Section 3(b)), then commencing on the day after the date such Shelf Registration ceases to be effective, Liquidated
Damages shall accrue on the Registrable Securities at a rate of 0.50% per annum on the Amount of Registrable Securities; 

provided,
however, that Liquidated Damages on the Registrable Securities may not accrue under more than one of the foregoing clauses (i), (ii) or (iii) at any one time; and provided
further, however, that (1) upon the filing of the Initial Shelf Registration as required hereunder (in the case of clause (a)(i) of this Section 3), (2) upon the
effectiveness of the Initial Shelf Registration or Subsequent Shelf Registration as required hereunder (in the case of clause (a)(ii) of this Section 3), or (3) upon the
effectiveness of a Shelf Registration which had ceased to remain effective (in the case of (a)(iii) of this Section 3), Liquidated Damages on the Registrable Securities as a result of
such clause (or the relevant subclause thereof), as the case may be, shall cease to accrue. It is understood and agreed that, notwithstanding any provision to the contrary, no Liquidated Damages shall
accrue on any Registrable Securities that are then covered by an effective Shelf Registration Statement. 

        (b)   Notwithstanding
paragraph (a) of this Section 3, the Company, upon written notice to the Holders, shall be permitted to suspend the effectiveness of a
Registration Statement covering the Registrable Securities for any bona fide reason whatsoever for up to 45 consecutive days (the "Deferral Period") in
any 90 day period without paying Liquidated Damages; provided, however, that in the event the disclosure relates to a previously undisclosed proposed or pending material business transaction,
the disclosure of which the Company determines in good faith would be reasonably likely to impede the Company's ability to consummate such transaction, the Company may extend a Deferral Period from
45 days to 60 days without paying Liquidated Damages; provided further, however, that Deferral Periods may not total more than 90 days in the aggregate in any twelve-month period.
The Company 

5

 

shall
not be required to specify in the written notice to the Holders the nature of the event giving rise to the Deferral Period. 

        (c)   So
long as Notes remain outstanding, the Company shall notify the Trustee within five Business Days after each and every date on which an event occurs in respect of
which Liquidated Damages are required to be paid. Any amounts of Liquidated Damages due pursuant to clause (a)(i), (a)(ii) or (a)(iii) of this Section 3 will be payable in
cash semi-annually on each March 8 and September 8 (each, a "Damages Payment Date"), commencing with the first such date
occurring after any such Liquidated Damages commences to accrue, to Holders to whom regular interest is payable on such Damages Payment Date, with respect to Notes that are Registrable Securities, and
to Persons that are registered Holders on February 22 or August 24 immediately prior to a Damages Payment Date with respect to Underlying Shares that are Registrable Securities. The
amount of Liquidated Damages for Registrable Securities will be determined by multiplying the applicable rate of Liquidated Damages by the Amount of Registrable Securities outstanding on the Damages
Payment Date following such Registration Default in the case of the first such payment of Liquidated Damages with respect to a Registration Default (and thereafter at the next succeeding Damages
Payment Date until the cure of such Registration Default), multiplied by a fraction, the numerator of which is the number of days such Liquidated Damages rate was applicable during such period
(determined on the basis of a 360-day year comprised of twelve 30-day months and, in the case of a partial month, the actual number of days elapsed), and the denominator of
which is 360. 

4.    Registration Procedures. 

        In
connection with the filing of any Registration Statement pursuant to Section 2 hereof, the Company shall effect such registrations to permit the sale of the securities covered
thereby in accordance with the intended method or methods of disposition thereof, and pursuant thereto and in connection with any Registration Statement filed by the Company hereunder the Company
shall: 

        (a)   Prepare
and file with the SEC, on or prior to the Filing Date, a Registration Statement or Registration Statements as prescribed by Section 2 hereof, and use all
reasonable efforts to cause each such Registration Statement to become effective and remain effective as provided herein; provided, however, that before filing any Registration Statement or Prospectus
or any amendments or supplements thereto, the Company shall furnish to and afford the Holders of the Registrable Securities covered by such Registration Statement a reasonable opportunity to review
copies of all such documents proposed to be filed (in each case, where possible, at least three Business Days prior to such filing, or such later date as is reasonable under the circumstances). The
Company shall not file any Registration Statement or Prospectus or any amendments or supplements thereto if the Holders of a majority in Amount of Registrable Securities covered by such Registration
Statement shall reasonably object in writing within such period. 

6

   
        (b)   Prepare and file with the SEC such amendments and post-effective amendments to each Shelf Registration, as may be necessary to keep such Registration
Statement continuously effective for the Effectiveness Period; cause the related Prospectus to be supplemented by any Prospectus supplement required by applicable law, and as so supplemented to be
filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; and comply with the provisions of the Securities Act and the Exchange Act applicable
to it with respect to the disposition of all Registrable Securities covered by such Registration Statement as so amended or in such Prospectus as so supplemented. The Company shall be deemed not to
have used all reasonable efforts to keep a Registration Statement effective during the Effectiveness Period if it voluntarily takes any action that would result in Selling Holders of the Registrable
Securities covered thereby not being able to sell such Registrable Securities during that period unless such action is required by applicable law or unless the Company is acting in compliance with
this Agreement, including without limitation the provisions of Section 4(i) hereof. 

        (c)   Notify
the Selling Holders and Designated Counsel, if any, promptly (but in any event within two Business Days), (i) when a Prospectus or any prospectus
supplement or post-effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective under
the Securities Act (including in such notice a written statement that any Holder may, upon request, obtain, at the sole expense of the Company, one conformed copy of such Registration Statement or
post-effective amendment including financial statements and schedules, documents incorporated or deemed to be incorporated by reference and exhibits), (ii) of the issuance by the
SEC of any stop order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of any preliminary prospectus or the initiation of any proceedings for
that purpose, (iii) of the happening of any event, the existence of any condition or any information becoming known that makes any statement made in such Registration Statement or related
Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in or amendments or supplements to
such Registration Statement, Prospectus or documents so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading and (iv) of the
Company's determination that a post-effective amendment to a Registration Statement would be appropriate. 

        (d)   Use
all reasonable efforts to prevent the issuance of any order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use
of a Prospectus and, if any such order is issued, to use all reasonable efforts to obtain the withdrawal of any such order at the earliest possible moment, and provide immediate notice to the Selling
Holders of the withdrawal of any such order. 

        (e)   Furnish
via e-mail to each Selling Holder and Designated Counsel, if any, at the sole expense of the Company, one conformed copy of the Registration
Statement or Registration Statements and each post-effective amendment thereto, including financial statements and schedules, and, if requested, all documents incorporated or deemed to be
incorporated therein by reference and all exhibits. 

        (f)    Deliver
to each Selling Holder and Designated Counsel, if any, at the sole expense of the Company, as many copies of the Prospectus (including each form of preliminary
prospectus) and each amendment or supplement thereto and any documents incorporated by reference therein as such Persons may reasonably request, provided, however, that no more than 75 copies of each
such document need be delivered to any such Person; and, subject to the second paragraph of Section 4(q) hereof, the Company hereby consents to the use of such Prospectus and each amendment or
supplement thereto by each of the Selling Holders of Registrable Securities and dealers, if any, in 

7

 

connection
with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto. 

        (g)   The
Company agrees to cause the Company's counsel to perform Blue Sky investigations and file registrations and qualifications required to be filed in connection with
the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities or offer and sale under the securities or Blue Sky laws of such jurisdictions
within the United States as any Selling Holder reasonably requests, keep each such registration or qualification (or exemption therefrom) effective during the period such Registration Statement is
required to be kept effective and do any and all other acts or things reasonably necessary or advisable under Blue Sky laws to enable the disposition in such jurisdictions of the Registrable
Securities covered by the applicable Registration Statement; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is
not then so qualified, (ii) take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject or (iii) subject itself to
taxation in any such jurisdiction where it is not then so subject. 

        (h)   Cooperate
with the Selling Holders and their respective counsel to facilitate the timely preparation and delivery of certificates representing shares of Registrable
Securities to be sold, which certificates shall not bear any restrictive legends (after effectiveness of the Shelf Registration) and shall be in a form eligible for deposit with The Depository Trust
Company; and enable such shares of Registrable Securities to be in such denominations and registered in such names as the Selling Holders may reasonably request. 

        (i)    Upon
the occurrence of any event contemplated by Section 4(c)(ii), 4(c)(iii) or 4(c)(iv) hereof, as promptly as practicable prepare and (subject to
Section 4(a) hereof) file with the SEC, at the sole expense of the Company, a supplement or post-effective amendment to the Registration Statement or a supplement to the related
Prospectus or any document incorporated or deemed to be incorporated therein by reference, or file any other required document so that, as thereafter delivered to the purchasers of the Registrable
Securities being sold thereunder, any such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were made, not misleading. 

        (j)    Prior
to the effective date of the first Registration Statement relating to the Registrable Securities, (i) provide the Trustee with certificates for the
Registrable Securities in a form eligible for deposit with The Depository Trust Company and (ii) provide a CUSIP number for the Registrable Securities. 

        (k)   Make
available at reasonable times for inspection by one or more representatives of the Selling Holders, designated in writing by Holders of a majority in Amount of
Registrable Securities to be included in such Registration Statement of such Registrable Securities being sold, and any attorney or accountant retained by any such Selling Holders (collectively, the
"Inspectors"), at the offices where normally kept, during reasonable business hours, at such time or times as shall be mutually convenient for the
Company and the Inspectors as a group, all financial and other records, pertinent corporate documents and instruments of the Company and its subsidiaries (collectively, the
"Records") as shall be reasonably necessary to enable them to exercise any applicable due diligence responsibilities, and cause the officers, directors
and employees of the Company and its subsidiaries to supply all information reasonably requested by any such Inspector in connection with such Registration Statement; provided, however, that such
inspections may not occur more than twice in any twelve-month period. Records that the Company determines, in good faith, to be confidential and any Records that it notifies the Inspectors are
confidential shall not be disclosed by any Inspector unless (i) the disclosure of such Records is necessary to avoid or correct a material misstatement or material omission in such Registration
Statement, (ii) the release of such Records is ordered pursuant to a subpoena or other 

8

 

order
from a court of competent jurisdiction or (iii) the information in such Records has been made generally available to the public other than through the acts of such Inspector; provided,
however, that prior notice shall be provided as soon as practicable, and in no event less than ten (10) Business Days prior to the potential disclosure, to the Company of the potential
disclosure of any information by such Inspector pursuant to clause (ii) of this sentence to permit the Company to obtain a protective order (or waive the provisions of this
paragraph (k)). Each Inspector shall take such actions as are reasonably necessary to protect the confidentiality of such information (if practicable) to the extent such actions are otherwise
not inconsistent with, an impairment of or in derogation of the rights and interests of the Holder or any Inspector, unless and until such information in such Records has been made generally available
to the public other than as a result of a breach of this Agreement. 

        (l)    Provide
(i) the Holders of the Registrable Securities to be included in such Registration Statement and Designated Counsel, if any, (ii) the sales or
placement agent, if any, thereof, and (iii) one counsel for such agents, reasonable opportunity to participate in the preparation of such Registration Statement, each prospectus included
therein or filed with the SEC, and each amendment or supplement thereto. 

        (m)  Comply
with all applicable rules and regulations of the SEC and make generally available to its security holders earning statements satisfying the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than 45 days after the end of any
12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year) commencing on the first day of the first fiscal quarter of the Company
after the effective date of a Registration Statement, which statements shall cover said 12-month periods. 

        (n)   Cause
the Indenture to be qualified under the TIA not later than the effective date of the first Registration Statement relating to the Registrable Securities; and in
connection therewith, cooperate with the Trustee and the Holders of the Registrable Securities and their respective counsel to effect such changes to the Indenture as may be required for the Indenture
to be so qualified in accordance with the terms of the TIA; and execute, and use all reasonable efforts to cause the Trustee to execute, all documents as may be required to effect such changes and all
other forms and documents required to be filed with the SEC to enable the Indenture to be so qualified in a timely manner. 

        (o)   Use
all reasonable efforts to cause the Registrable Securities covered by any Shelf Registration Statement to be registered with or approved by such other governmental
agencies or authorities as may be reasonably necessary to enable the Selling Holder or Holders thereof to consummate the disposition of such Registrable Securities, except as may be required solely as
a consequence of the nature of such selling Holder's business, in which case the Company will cooperate in all reasonable respects with the filing of such Registration Statement and the granting of
such approvals. 

        (p)   If
requested by Designated Counsel, if any, or the Holders of the majority in Amount of Registrable Securities (i) promptly incorporate in a prospectus supplement
or post-effective amendment such information as the Designated Counsel, if any, or such Holders reasonably determine is necessary to be included therein, (ii) make all required
filings of such prospectus supplement or such post-effective amendment as soon as reasonably practicable after the Company has received notification of the matters to be incorporated in
such prospectus supplement or post-effective amendment and (iii) supplement or make amendments to such Registration Statement, provided, however, that the Company shall not be
required to take any of the actions set forth in this subclause (p) in the event the Company has received the written advice of outside counsel that such action is not required by applicable
laws or regulations. 

        (q)   Use
all reasonable efforts to take all other steps necessary or advisable to effect the registration of the Registrable Securities covered by a Registration Statement
contemplated hereby. 

9

 

        Each
Holder agrees, by acquisition of the Registrable Securities, that no Holder shall be entitled to sell any of such Registrable Securities pursuant to a Registration Statement or to
receive a Prospectus relating thereto, unless such Holder has furnished the Company with a Notice and Questionnaire as required pursuant to Section 2(d) hereof (including the information
required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. Each Selling Holder agrees promptly to furnish to the Company all information required to
be disclosed in order to make the information previously furnished to the Company by such Selling Holder not misleading and any other information regarding such Selling Holder and the distribution of
such Registrable Securities as the Company may from time to time reasonably request. Any sale of any Registrable Securities by any Holder shall constitute a representation and warranty by such Holder
that the information relating to such Holder and its plan of distribution is as set forth in the Prospectus delivered by such Holder in connection with such disposition, that such Prospectus does not
as of the time of such sale contain any untrue statement of a material fact relating to or provided by such Holder or its plan of distribution and that such Prospectus does not as of the time of such
sale omit to state any material fact relating to or provided by such Holder or its plan of distribution necessary to make the statements in such Prospectus, in the light of the circumstances under
which they were made, not misleading. 

        The
Company may require each Selling Holder of Registrable Securities as to which any registration is being effected to furnish to the Company such additional information regarding such
Holder and the distribution of such Registrable Securities as the Company may, from time to time, reasonably request to the extent necessary or advisable to comply with the Securities Act. The Company
may exclude from such registration the Registrable Securities of any Selling Holder if such Holder fails to furnish such additional information within 20 Business Days after receiving such request.
Each Selling Holder as to which any Shelf Registration is being effected agrees to furnish promptly to the Company all information required to be disclosed so that the information previously furnished
to the Company by such Holder is not materially misleading and does not omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading in
light of the circumstances under which they were made. 

        Each
Holder of Registrable Securities agrees by acquisition of such Registrable Securities that, upon actual receipt of any notice from the Company of the Company suspending the
effectiveness of the Registration Statement pursuant to Section 3(b) hereof, or upon the happening of any event of the kind described in Section 4(c)(ii), 4(c)(iii) or
4(c)(iv) hereof, such Holder will forthwith discontinue disposition of such Registrable Securities covered by such Registration Statement or Prospectus until such Holder's receipt of the copies
of the supplemented or amended Prospectus contemplated by Section 4(i) hereof, or until it is advised in writing by the Company that the use of the applicable Prospectus may be resumed,
and has received copies of any amendments or supplements thereto. Each Holder agrees to keep any such notice in confidence. 

10

   
5.    Registration Expenses. 

        (a)   All
fees and expenses incident to the performance of or compliance with this Agreement by the Company shall be borne by the Company, including, without limitation,
(i) all registration and filing fees (including, without limitation, fees and expenses of compliance with state securities or Blue Sky laws, including, without limitation, reasonable fees and
disbursements of counsel in connection with Blue Sky qualifications of the Registrable Securities and determination of the eligibility of the Registrable Securities for investment under the laws of
such jurisdictions as provided in Section 4(g) hereof), (ii) printing expenses, including, without limitation, expenses of printing certificates for Registrable Securities in a form
eligible for deposit with The Depository Trust Company and of printing prospectuses if the printing of prospectuses is requested by the Holders of the majority in Amount of Registrable Securities

all Registration Statements and any other documents necessary in order to comply with this Agreement. Notwithstanding anything in this Agreement to the contrary, each Holder shall pay all brokerage
commissions with respect to any Registrable Securities sold by it and, except as set forth in Section 5(b) below the Company shall not be responsible for the fees and expenses of any counsel,
accountant or advisor for the Holders. 

        (b)   The
Company shall reimburse the Holders of the Registrable Securities being registered in a Shelf Registration for the reasonable fees and disbursements, of Designated
Counsel; provided, however, that in no event shall the Company be required to pay more than $10,000 in the aggregate with respect to such fees and disbursements. 

6.    Indemnification. 

        The
Company agrees to indemnify and hold harmless (a) each Holder (which, for the absence of doubt, for purposes of this Section 6 shall include the Initial Purchasers),
(b) each Person, if any, who controls (within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the Persons referred to
in this clause (b) being hereinafter referred to as a "Controlling Person"), (iii) the respective officers, directors, partners,
employees, representatives and agents of any Holder or any controlling person (any person referred to in clause (a), (b) or (c) may hereinafter be referred to as an
"Indemnified Holder"), against any losses, claims, damages or liabilities to which such Indemnified Holder may become subject under the Securities Act
or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue
statement of any material fact contained in any Registration Statement or Prospectus, or any amendment or supplement thereto or any related preliminary prospectus or (ii) the omission or
alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in the light of the circumstances in which they were made;
provided, however, that the Company will not be liable under this paragraph, (x) to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement
or alleged untrue statement, or omission or alleged omission made in any such Registration Statement or Prospectus, or any amendment or supplement thereto or any related preliminary prospectus in
reliance upon and in conformity with written information relating to any Holder furnished to the Company by or on behalf of such Holder specifically for use therein or (y) with respect to any
untrue statement or alleged untrue statement, or omission or alleged omission made in any preliminary prospectus if the person asserting any such loss, claim, damage or liability who purchased
Registrable Securities which are the subject thereof did not receive a copy of the Prospectus

(or
of the preliminary prospectus as then amended or supplemented if the Company shall have furnished such Indemnified Holder with such amendment or supplement thereto on a timely basis) at or prior
to the written confirmation of the sale of such Registrable Securities to such person and, in any case where such delivery is required by applicable law and the untrue statement or alleged untrue
statement or omission or alleged omission of a material fact made in such preliminary prospectus was corrected in the Prospectus (or the preliminary prospectus as then amended or supplemented if the
Company shall have furnished such Indemnified Holder with such amendment or supplement thereto on a timely basis). The Company shall notify such Indemnified Holder promptly of the institution, threat
or assertion of any claim, proceeding (including any governmental investigation) or litigation in connection with the matters addressed by this Agreement that involves the Company or such Indemnified
Holder. 

        The
Company agrees to reimburse each Indemnified Holder promptly after demand for any legal or other out-of-pocket expenses reasonably incurred by such
Indemnified Holder in connection with investigating or defending any such loss, claim, damage or liability, any action or proceeding or in responding to a subpoena or governmental inquiry related to
the offering of the Registrable Securities, whether or not such Indemnified Holder is a party to any action or proceeding. In the event that it is finally judicially determined that an Indemnified
Holder was not entitled to receive payments for legal and other expenses pursuant to this paragraph, such Indemnified Holder will promptly return all sums that had been advanced pursuant hereto. 

        Each
Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, officers, partners, employees, representatives and agents, and each Person who
controls the Company (within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) to the same extent as the indemnity provided in the first paragraph
of this Section 6 from the Company to each Holder, but only with reference to such losses, claims, damages or liabilities which are caused by any untrue statement or omission or alleged untrue
statement or omission made in reliance upon and in conformity with information relating to a Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement
or Prospectus, or any amendment or supplement thereto or any related preliminary prospectus. The liability of any Holder under this paragraph shall in no event exceed the proceeds received by such
Holder from sales of Registrable Securities giving rise to such obligation. 

        In
case any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Person in respect of which
indemnity may be sought pursuant to either of the first and third paragraphs of this Section 6, such Person (the "Indemnified Person") shall
promptly notify the Person or Persons against whom such indemnity may be sought (each an "Indemnifying Person") in writing. No indemnification provided
for in the first or third paragraphs of this Section 6 shall be available to any Person who shall have failed to give notice as provided in this paragraph if the party to whom notice was not
given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the
Indemnifying Person or Persons from any liability which it or they may have to the Indemnified Person for contribution or otherwise than on account of the provisions of the first and third paragraphs
of this Section 6. In case any such proceeding shall be brought against any Indemnified Person and it shall notify the Indemnifying Person of the commencement thereof, the Indemnifying Person
shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other Indemnifying Person similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such Indemnified Person and shall pay as incurred (or within 30 days of presentation) the fees and disbursements reasonably incurred by such counsel related to such proceeding.
In any such proceeding, any Indemnified Person shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the Indemnifying Person shall pay as incurred (or
within 30 days of presentation) the fees and expenses reasonably 

12

 

incurred
by the counsel retained by the Indemnified Person in the event (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the retention of such counsel,
(ii) the named parties to any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests between them or (iii) the Indemnifying Person shall have failed to assume the defense and employ counsel reasonably
acceptable to the Indemnified Person within a reasonable period of time after notice of commencement of the action. It is understood that the Indemnifying Person shall not, in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such Indemnified Persons. Such firm shall be
designated in writing by Holders of a majority in Amount of Registrable Securities in the case of parties indemnified pursuant to the first paragraph of this Section 6 and by the Company in the
case of parties indemnified pursuant to the third paragraph of this Section 6. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its prior
written consent but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify the Indemnified Person from and against any loss or
liability by reason of such settlement or judgment. In addition, the Indemnifying Person will not, without the prior written consent of the Indemnified Person, settle or compromise or consent to the
entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any Indemnified Person is an actual or potential party
to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each Indemnified Person from all liability arising out of such claim, action or
proceeding. 

        To
the extent the indemnification provided for in this Section 6 is unavailable to or sufficient to hold harmless an Indemnified Person under the first or third paragraph of this
Section 6 in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, except by reason of the exceptions set forth in the first
or third paragraphs of this Section 6 or the failure of the Indemnified Person to give notice as required in the fourth paragraph of this Section 6,
then each Indemnifying Person shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Person on the one hand and the Indemnified Person on the other hand from the offering of the
Notes pursuant to the Purchase Agreement and the Registrable Securities pursuant to any Shelf Registration. If, however, the allocation provided by the immediately preceding sentence is not permitted
by applicable law then each Indemnifying Person shall contribute to such amount paid or payable by such Indemnified Person in such proportion as is appropriate to reflect not only such relative
benefits but also the relative fault of the Indemnifying Person on the one hand and the Indemnified Person on the other in connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and
any Indemnified Holder on the other shall be deemed to be in the same proportion as the total net proceeds (before deducting expenses) received by the Company from the offering and sale of the Notes
bear to the total net proceeds received by such Indemnified Holder from sales of Registrable Securities giving rise to such obligations. The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one
hand or such Indemnified Holder on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

        The
Company and the Initial Purchasers agree that it would not be just and equitable if contributions pursuant to the immediately preceding paragraph of this Section 6 were
determined by pro rata allocation or by any other method of allocation which does not take account of the equitable 

13

 

considerations
referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) referred to in the immediately preceding paragraph shall be deemed to include any non-reimbursed legal or other expenses reasonably incurred by such
Indemnified Person in connection with investigating or defending any such action or claim or enforcing any rights hereunder. Notwithstanding the provisions of this paragraph and the immediately
preceding paragraph of this Section 6, (i) in no event shall any Holder be required to contribute any amount in excess of the amount by which the net proceeds received by such Holder
from the offering or sale of the Registrable Securities pursuant to a Shelf Registration Statement exceeds the amount of damages which such Holder would have otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission and (ii) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 

        Except
as otherwise provided in this Section 6, any losses, claims, damages, liabilities or expenses for which an Indemnified Person is entitled to indemnification or contribution
under this Section 6 shall be paid by the Indemnifying Person to the Indemnified Person as such losses, claims, damages, liabilities or expenses are incurred (or within 30 days of
presentation). 

        The
remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in
equity. 

        The
indemnity and contribution agreements contained in this Section 6 shall remain operative and in full force and effect regardless of (i) any termination of this
Agreement, (ii) any investigation made by or on behalf of any Holder or any Person controlling any Holder or by or on behalf of the Company, its officers or directors or any other Person
controlling any of the Company and (iii) acceptance of and payment for any of the Registrable Securities. 

7.    Rules 144 and 144A. 

        The
Company covenants that it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder
in a timely manner in accordance with the requirements of the Securities Act and the Exchange Act and, for so long as any Registrable Securities remain outstanding, if at any time the Company is not
required to file such reports, it will, upon the request of any Holder or beneficial owner of Registrable Securities, make available such information necessary to permit sales pursuant to
Rule 144A under the Securities Act. The Company further covenants that, for so long as any Registrable Securities remain outstanding, it will use all reasonable efforts to take such further
action as any Holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holder to sell Registrable Securities without registration under the
Securities Act within the limitation of the exemptions provided by (a) Rule 144 and Rule 144A under the Securities Act, as such rules may be amended from time to time, or
(b) any similar rule or regulation hereafter adopted by the SEC. The Company will provide a copy of this Agreement to prospective purchasers of Registrable Securities identified to the Company
by the Initial Purchasers upon request in writing. Upon the request of any Holder, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements.
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act or list its securities on any
exchange other than PORTAL or Nasdaq. 

8.    Underwritten Registrations. 

        No
Holder of Registrable Securities may participate in any Underwritten Registration hereunder. 

14

 

9.    Miscellaneous. 

        (a)   No Inconsistent Agreements. The Company has not, as of the date hereof, and the Company shall not, after the date of this
Agreement, enter into any agreement with respect to any of its securities that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts
with the provisions hereof. 

        (b)   Adjustments Affecting Registrable Securities. The Company shall not, directly or indirectly, take any action with respect
to the Registrable Securities as a class that would adversely affect the ability of the Holders of Registrable Securities to include such Registrable Securities in a registration undertaken pursuant
to this Agreement. 

        (c)   Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or
consents to departures from the provisions hereof may not be given, otherwise than with the prior written consent of the Company and the Holders of not less than the majority in Amount of Registrable
Securities; provided, however, that Section 6 and this Section 9(c) may not be amended, modified or supplemented without the prior written consent of the Company and each Holder
(including, in the case of an amendment, modification or supplement of Section 6, any Person who was a Holder of Registrable Securities disposed of pursuant to any Registration Statement).
Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders of Registrable Securities whose
securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect, impair, limit or compromise the rights of other Holders of Registrable Securities may be
given by Holders of at least a majority in principal amount of the Registrable Securities being sold by such Holders pursuant to such Registration Statement. 

        (d)   Notices. All notices and other communications (including without limitation any notices or other communications to the
Trustee) provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, next-day air courier or facsimile:

and Questionnaire or any amendment thereto, in which case such information shall control.

be counted in determining whether such consent or approval was given by the Holders of such required percentage. 

        (k)   Third-Party Beneficiaries. Holders of Registrable Securities are intended third party beneficiaries of this Agreement and
this Agreement may be enforced by such Persons.
