Section 2.2 Execution and Authentication.



An Officer shall sign the Securities for the Company by manual or facsimile signature attested by the manual or facsimile signature of the Secretary or an
Assistant Secretary of the Company. Typographic and other minor errors or defects in any such facsimile signature shall not affect the validity or enforceability of any Security which has been authenticated and delivered by the Trustee.



If an Officer whose signature is on a Security no longer holds that office
at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.



A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.



The Trustee shall
authenticate and make available for delivery Securities for original issue in the aggregate principal amount of up to $70,000,000 upon receipt of a written order or orders of the Company signed by two Officers of the Company (a Company
Order). The Company Order shall specify the amount of Securities to be authenticated, shall provide that all such Securities will be represented by a Restricted Global Security and the date on which



11



---

each original issue of Securities is to be authenticated. The aggregate principal amount of Securities outstanding at any time may not exceed $70,000,000
except as provided in Section 2.7 hereof.



The Trustee shall
act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each
reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company.



The Securities shall be issuable only in registered form without coupons and
only in denominations of $1,000 principal amount and any integral multiple thereof.



Section 2.3 Registrar, Paying Agent and Conversion Agent.



The Company shall maintain one or more offices or agencies where Securities may be presented for registration of transfer or for exchange (each, a Registrar), one or more offices or agencies where
Securities may be presented for payment (each, a Paying Agent), one or more offices or agencies where Securities may be presented for conversion (each, a Conversion Agent) and one or more offices or agencies
where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company will at all times maintain a Paying Agent, Conversion Agent, Registrar and an office or agency where notices and demands to
or upon the Company in respect of the Securities and this Indenture may be served. One of the Registrars (the Primary Registrar) shall keep a register of the Securities and of their transfer and exchange.



The Company shall enter into an appropriate agency agreement with any Agent
not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture. If the Company fails to
maintain a Registrar, Paying Agent, Conversion Agent or agent for service of notices and demands in any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the
Company may act as Registrar, Paying Agent (except as provided in Section 6.1) or Conversion Agent.



The Company hereby initially designates the Trustee as Paying Agent, Registrar, Custodian and Conversion Agent, and each of the Corporate Trust Office of
the Trustee and the office or agency of the Trustee (which shall initially be 135 South LaSalle Street, Suite 1960 Chicago, IL 60603, Attention: Corporate Trust Services) one such office or agency of the Company for each of the aforesaid purposes.



Section 2.4 Paying Agent to Hold Money in Trust.



Prior to 11:00 a.m., New York City time, on each due date of the principal
of or interest and Additional Interest, if any, on any Securities, the Company shall deposit with a Paying Agent a sum sufficient to pay such principal or interest and Additional Interest, if any, so becoming due. Subject to Section 5.2 hereof, a
Paying Agent shall hold in trust for the benefit of



12



---

Holders or the Trustee all money held by the Paying Agent for the payment of principal of or interest and Additional Interest, if any, on the Securities, and
shall notify the Trustee of any Default by the Company (or any other obligor on the Securities) in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall, before 11:00 a.m., New York City time, on each
due date of the principal of or interest and Additional Interest, if any, on any Securities, segregate the money and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee, and
the Trustee may at any time during the continuance of any Default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent
(other than the Company) shall have no further liability for the money. Upon any Insolvency or Bankruptcy Proceeding relating to the Company, the Trustee shall serve as Paying Agent for the Securities.



Section 2.5 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 and shall otherwise comply with Section 312(a) of the TIA. If the Trustee is not the Primary Registrar, the Company shall furnish to the Trustee at least five
Business Days prior to each Interest Payment Date, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders.



Section 2.6 Transfer and Exchange.



(a) Subject to compliance with any applicable additional requirements
contained in Section 2.12 hereof, when a Security is presented to a Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized denominations, the Registrar
shall register the transfer or make the exchange as requested; provided, however, that every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an assignment form and, if
applicable, a transfer certificate each in the form included in Exhibit A hereto, and in form satisfactory to the Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers
and exchanges, upon surrender of any Security for registration of transfer or exchange at an office or agency maintained pursuant to Section 2.3 hereof, the Company shall execute and the Trustee shall authenticate Securities of a like aggregate
principal amount at the Registrars request. Any exchange or transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto, and provided, that this sentence shall not apply to any exchange pursuant to Section 2.7, 2.10, 2.12(a), 3.6, 3.7, 4.2 (last paragraph) or 10.5.



None of the Company, any Registrar or the Trustee shall be required to exchange or register a transfer of any Securities or
portions thereof in respect of which a Redemption Notice has been issued by the Company or any Change of Control Purchase Notice or Optional Purchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of the
purchase of a Security in part, the portion thereof not to be purchased).



13



---

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



(b) Any Registrar appointed pursuant to Section 2.3 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.



(c) Each Holder of a Security agrees to indemnify the Company and the Trustee against any liability that may result from the transfer, exchange or
assignment of such Holders Security in violation of any provision of this Indenture and/or applicable United States federal or state securities law.



The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or other beneficial owners of interests in any Global Security) other than to require delivery of
such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express
requirements hereof.



Section 2.7 Replacement Securities.



If any mutilated Security is surrendered to the Company,
a Registrar or the Trustee, or the Company, a Registrar and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the applicable Registrar and the Trustee such
security or indemnity as will be required by them to save each of them harmless, then, in the absence of notice to the Company, such Registrar or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute,
and upon its written request the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not
contemporaneously outstanding.



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 redeemed or purchased by the Company pursuant to Article 3 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 2.7, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable
fees and expenses of the Trustee or the Registrar) in connection therewith.



Every new Security issued pursuant to this Section 2.7 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the
mutilated, destroyed, lost or stolen Security shall be at any time



14



---

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



Section 2.8 Outstanding Securities.



Securities outstanding at any time are all Securities authenticated by the
Trustee, except for those canceled by it, those converted pursuant to Article 4, those delivered to it for cancellation or surrendered for transfer or exchange and those described in this Section 2.8 as not outstanding.



If a Security is replaced pursuant to Section 2.7, it ceases to be
outstanding unless the Company receives proof satisfactory to it that the replaced Security is held by a protected purchaser as defined in Section 8-303 of the New York Uniform Commercial Code.



If a Paying Agent (other than the Company or an Affiliate of the Company)
holds on a Redemption Date, Change of Control Purchase Date, Optional Purchase Date or the Final Maturity Date money sufficient to pay the principal of and accrued interest and Additional Interest, if any, on Securities (or portions thereof) payable
on that date, then on and after such Redemption Date, Change of Control Purchase Date, Optional Purchase Date or the Final Maturity Date, as the case may be, such Securities (or portions thereof, as the case may be) shall cease to be outstanding and
interest and Additional Interest, if any, on them shall cease to accrue.



Subject to the restrictions contained in Section 2.9, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.



Section 2.9 Treasury Securities.



In determining whether the Holders of the required principal amount of
Securities have concurred in any notice, direction, waiver or consent, Securities owned by the Company, any other obligor on the Securities or by any Affiliate of the Company or of such other obligor shall be disregarded, except that, for purposes
of determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Securities which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded. Securities so owned which
have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgees right so to act with respect to the Securities and that the pledgee is not the Company or any other obligor on
the Securities or any Affiliate of the Company or of such other obligor.



Section 2.10 Temporary Securities.



Until definitive Securities are ready for delivery, the Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in
the form of definitive Securities but may have variations that the Company considers appropriate for temporary



15



---

Securities and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and
deliver definitive Securities in exchange for temporary Securities.



Holders of temporary Securities shall be entitled to all of the benefits of this Indenture.



Section 2.11 Cancellation.



The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee or its agent any Securities surrendered to them for
transfer, exchange, payment or conversion. The Trustee and no one else shall promptly cancel, in accordance with its standard procedures, all Securities surrendered for transfer, exchange, payment, conversion or cancellation and shall deliver the
canceled Securities to the Company. All Securities which are redeemed, purchased or otherwise acquired by the Company or any of its Subsidiaries prior to the Final Maturity Date pursuant to a redemption by the Company pursuant to Section 3.1, a
Change of Control Offer or Optional Purchase Offer shall be delivered to the Trustee for cancellation, and the Company may not hold or resell such Securities or issue any new Securities to replace any such Securities or any Securities that any
Holder has converted pursuant to Article 4 hereof.



Section 2.12 Legend;
Additional Transfer and Exchange Requirements.



(a) If
Securities are issued upon the transfer, exchange or replacement of Securities subject to restrictions on transfer and bearing the legends set forth on the forms of Securities attached hereto as Exhibit A or additional legends required by
law, stock exchange rules or usage (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 if so requested by the Company or such Registrar, as may be reasonably acceptable to the Company and the Registrar, that
neither the Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule 144 under the Securities Act or that such Securities are not restricted
within the meaning of Rule 144 under the Securities Act; provided that no such evidence need be supplied in connection with the sale of such Security pursuant to a registration statement under the Securities Act that is effective at the time of such
sale. Upon (i) provision of such satisfactory evidence if requested, 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 or any portion thereof. 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 may be reinstated by the Company.



(b) A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that the foregoing
shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global



16



---

Security in accordance with the terms of such Security. No transfer of a Security to any Person shall be effective unless and until such Security has been
registered in the name of such Person. Notwithstanding any other provisions of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be made only in accordance with this Section 2.12.



(c) Subject to the succeeding paragraph, every Security shall be subject to
the restrictions on transfer provided in the Legend. Whenever any Restricted Security other than a Restricted Global Security is presented or surrendered for registration of transfer or 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 A, dated the date of such surrender and signed by the Holder of such Security, as to compliance with such
restrictions on transfer. The Registrar shall not be required to accept for such registration of transfer or exchange any Security not so accompanied by a properly completed certificate.



(d) The restrictions imposed by the Legend upon the transferability of any Security shall cease and terminate when such
Security has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto) or, if earlier, upon the expiration of the
holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), unless otherwise required by law or stock exchange rules. Any Security as to which such restrictions on transfer shall have expired
in accordance with their terms or shall have terminated may, upon a surrender of such Security for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer have
terminated by reason of a transfer in compliance with Rule 144 or any successor provision, by, if requested, an opinion of counsel 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 restrictive 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.



(e) 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.



(f) 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 (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary
for such Global Security or such Depositary has ceased to be a clearing agency registered under the Exchange Act, and a successor



17



---

Depositary is not appointed by the Company within 90 days, (B) the Company has provided the Depositary with written notice that it has decided to discontinue
use of the system of book-entry transfer through the Depositary or any successor Depositary or (C) an Event of Default has occurred and is continuing with respect to the Securities. Any Global Security exchanged pursuant to clauses (A) or (B) above
shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (C) 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. Only Restricted Securities shall be issued in exchange for Restricted Global Securities. Any Global Security
to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting
as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the
records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof.



(iii) Subject to the provisions of clause (v) below, the
registered Holder may grant proxies and otherwise authorize any Person, including Agent Members 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 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.



18

Section 2.13 CUSIP Numbers.



The Company in issuing the Securities may use one or more CUSIP numbers (if then generally in use), and, if so,
the Trustee shall use CUSIP numbers in notices of redemption or purchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the
Securities or as contained in any notice of purchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such purchase shall not be affected by any defect in or omission of such numbers. The
Company will promptly notify the Trustee of any change in the CUSIP numbers.



ARTICLE III.

REDEMPTION AND REPURCHASE



Section 3.1 Right to Redeem; Notice to Trustee. The Securities may be redeemed
at the election of the Company, as a whole or from time to time in part, at any time on or after October 15, 2008, at a price (the Redemption Price) equal to 100% of the principal amount of the Securities, together with accrued and
unpaid interest and Additional Interest, if any, up to, but not including, the date of redemption (each a Redemption Date); provided, that if a Redemption Date falls after an Interest Payment Record Date and on or before an
Interest Payment Date, then the interest and Additional Interest, if any, will be payable to the Holders in whose name the Securities are registered at the close of business on the Interest Payment Record Date.



If the Company elects to redeem Securities pursuant to this Section 3.1 and
paragraph 5 of the Securities, it shall notify the Trustee at least 30 days prior to the Redemption Date as fixed by the Company (the Redemption Notice) (unless a shorter notice shall be satisfactory to the Trustee) of the
Redemption Date and the principal amount of Securities to be redeemed. If fewer than all of the Securities are to be redeemed, the record date relating to such redemption shall be selected by the Company and given to the Trustee, which record date
shall not be less than ten days after the date of notice to the Trustee.



Except as set forth in this Section 3.1 and paragraph 5 of the Securities, the Company shall not have the option to redeem the Securities prior to October 15, 2008.



Section 3.2 Selection of Securities to Be Redeemed. If fewer than all the
Securities are to be redeemed, the Trustee shall select the Securities to be redeemed or purchased by lot, or in the Trustees discretion, on a pro rata basis. In the event of partial redemption by lot, the particular Securities to be
redeemed shall be selected, unless otherwise provided herein, not less than 20 nor more than 60 days prior to the Redemption Date by the Trustee from the outstanding Securities not previously called for redemption. If a portion of Securities is
selected for partial redemption and a Holder elects to convert a portion of Securities pursuant to Article 4 hereof, the converted portion of the Securities will be deemed to be the portion selected for redemption. Securities which 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.



19



---

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and,
in the case of any Security selected for partial redemption, the principal amount thereof to be redeemed. Securities and portions of Securities selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all the Securities of
a Holder are to be redeemed, the entire outstanding amount of Securities held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Securities
called for redemption also apply to portions of Securities called for redemption.



Section 3.3 Notice of Redemption. At least 20 days but not more than 60 days before a Redemption Date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Securities
are to be redeemed at such Holders registered address.



The notice shall identify the Securities to be redeemed and shall state:



(a) the Redemption Date;



(b)
the Redemption Price;



(c) the then current Conversion Price;



(d) if any Security is being redeemed in part, the portion of
the principal amount of such Security to be redeemed and that, after the Redemption Date upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion shall be issued upon cancellation of the
original Security;



(e) the name and address of the Paying
Agent and Conversion Agent;



(f) that Securities called for
redemption must be presented and surrendered to a Paying Agent to collect the Redemption Price;



(g) that Holders who wish to convert Securities must surrender such Securities for conversion no later than the close of business on the second Business
Day immediately preceding the Redemption Date and must satisfy the other requirements in paragraph 8 of the Securities;



(h) that, unless the Company defaults in making such redemption payment, interest including Additional Interest, if any, on Securities called for
redemption ceases to accrue on and after the applicable Redemption Date;



(i) the CUSIP number, if any, printed on the Securities being redeemed; and



(j) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Securities.



At the Companys request, the Trustee shall give the
notice of redemption in the Companys name and at its expense; provided,however, that the Company shall have delivered



20



---

to the Trustee, at least 30 days prior to the applicable Redemption Date, an Officers Certificate requesting that the Trustee give such notice and
setting forth the information to be stated in such notice as provided in the preceding paragraph.



Section 3.4 Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.3 hereof, Securities called for redemption (unless previously converted) become due and
payable on the applicable Redemption Date at the Redemption Price stated in the notice. A notice of redemption may not be conditional. The Redemption Price shall be paid to a Holder promptly following the later of (i) the Redemption Date with
respect to the Security of such Holder, and (ii) the time of delivery of such Security to a Paying Agent by the Holder thereof for purchase pursuant to the Redemption Notice, provided, that if a Redemption Date falls after an Interest Payment
Record Date and on or before an Interest Payment Date, then the interest and Additional Interest, if any, will be payable to the Holders in whose name the Securities are registered at the close of business on the Interest Payment Record Date.



Section 3.5 Deposit of Redemption Price. On or before 11:00 a.m.
New York City time on the Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (other than the Company or an Affiliate of the Company) an amount of money (in immediately available funds if deposited on such Redemption
Date) sufficient to pay the aggregate Redemption Price of all the Securities or portions thereof that are to be purchased on such Redemption Date. The manner in which the deposit required by this Section 3.5 is made by the Company shall be at the
option of the Company, provided that such deposit shall be made in a manner such that the Trustee or a Paying Agent shall have immediately available funds on or before 11:00 a.m. New York City time on the Redemption Date.



If a Paying Agent holds, in accordance with the terms hereof, Cash sufficient
to pay the Redemption Price of any Security for which a Redemption Notice has been tendered in accordance with this Indenture then, on the Redemption Date, such Security will cease to be outstanding and the rights of the Holder in respect thereof
shall terminate (other than the right to receive the Redemption Price as aforesaid).



Section 3.6 Securities Redeemed in Part. Any Security that is to be purchased only in part shall be surrendered at the office of a Paying Agent, and promptly after the Redemption Date the Company shall execute and the Trustee
shall authenticate and deliver to the Holder of such Security, without service charge except that 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, a new
Security or Securities, of such authorized denomination or denominations as may be requested by such Holder, in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not
purchased.



Section 3.7 Offer to Repurchase Upon Change of Control.



(a) If at any time that Securities remain outstanding
there shall occur a Change of Control, each Holder will have the right to require the Company to repurchase all of its Securities not previously called for redemption, or any portion of such Securities, at a purchase price (the Change of
Control Purchase Price) equal to 100% of the principal amount of all such Securities, plus accrued and unpaid interest, including Additional Interest, if any, on



21



---

such Securities to, but not including, the Change of Control Purchase Date (as defined below) provided, that if a Change of Control Purchase Date
falls after an Interest Payment Record Date and on or before an Interest Payment Date, then the interest and Additional Interest, if any, will be payable to the Holders in whose name the Securities are registered at the close of business on the
Interest Payment Record Date. Upon the occurrence of a Change of Control, the Company shall make an offer (a Change of Control Offer) to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple thereof)
of each Holders Securities, as of the date that is 30 Business Days after the occurrence of the Change of Control (the Change of Control Purchase Date), subject to satisfaction by or on behalf of any Holder of the
requirements set forth in subsection (c) of this Section 3.7.



A Change of Control shall be deemed to have occurred if any of the following occurs after the date hereof:



| | (1) | any Person or group is or becomes the beneficial owner, directly or indirectly, of shares of the Companys Voting Stock representing 50% or
more of the total voting power of all outstanding classes of the Companys Voting Stock or has the power, directly or indirectly, to elect a majority of the members of the board of directors of the Company;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (2) | the Company consolidates with or merges with or into another Person or sells, assigns, conveys, transfers, leases or otherwise disposes of all or substantially all of its assets or

Cash, stock or other property unless all of the consideration, excluding Cash payments for fractional shares and Cash payments made pursuant to dissenters appraisal rights, in a merger or consolidation otherwise constituting a Change in
Control consists of shares of common stock, depositary receipts or other certificates representing common equity interests traded on a national securities exchange or quoted on the NNM, or will be so traded immediately following such merger or
consolidation, and as a result of such merger or consolidation the Securities become convertible solely into such common stock, depositary receipts or other securities representing common equity interests;



provided, however, that, if such Security is called for redemption or submitted or
presented for purchase pursuant to Article 3, such conversion right shall terminate at the close of business on



33



---

the second Business Day preceding the Redemption Date, the Change of Control Purchase Date or Optional Purchase Date, as applicable, for such Security or
such earlier date as the Holder presents such Security for purchase (unless the Company shall Default in making the Redemption Price Change of Control Purchase Price or Optional Purchase Price payment when due, in which case the conversion right
shall terminate at the close of business on the date such Default is cured and such Security is purchased). 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 4.



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



A Holder of a Security is not entitled to receive any accrued and unpaid interest including Additional Interest, if any, in respect of the Security upon,
or from and after, the conversion of such Security.



A Holder
of Securities is not entitled to any rights of a holder of Common Stock until such Holder has converted its Securities to Common Stock, and only to the extent such Securities are deemed to have been converted into Common Stock pursuant to this
Article 4.



(g) Conversion upon Change of Control. If
the Company elects to make a distribution to holders of Common Stock pursuant to subparagraphs (d) and (e) above, the Company must notify the Holders at least 20 days prior to the ex-dividend date for such distribution. Once the Company has given
such notice, a Holder may surrender its Securities for conversion at any time until the earlier of the close of business on the Business Day prior to the ex-dividend date or the Companys announcement that such distribution will not take place.



The Company will provide written notice to the Trustee upon
the occurrence of any of the conversion events specified in this Section 4.1.



Section 4.2Conversion Procedure.



To convert a Security, a Holder must (a) complete and manually sign the Conversion Notice on the back of the Security (the Conversion Notice) and deliver such notice to a Conversion Agent, (b)
surrender the Security to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, (d) pay any transfer or similar tax, if required, and (e) satisfy any additional requirement
under paragraph 8 of the Security, if any. The date on which the Holder satisfies all of those requirements is the Conversion Date. Upon conversion of a Security, the Company may choose to deliver shares of Common Stock, Cash or a
combination of shares of Common Stock and Cash as set forth in Section 4.15. Anything herein to the contrary notwithstanding, in the case of Global Securities, Conversion Notices may be delivered and such Securities may be surrendered for conversion
in accordance with the Applicable Procedures as in effect from time to time.



34



---

Each conversion shall be deemed to have been effected as to any Security (or portion thereof) as of the
close of business on the later of (i) the Conversion Date, (ii) the expiration of the Cash Settlement Notice Period, or (iii) if the Company elects to pay Cash in lieu of Common Stock pursuant to Section 4.15, the expiration of the Cash Settlement
Averaging Period, and the person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become on said date the Holder of record of the shares represented thereby;
provided, however, that in case of any such surrender of a Security on any date when the stock transfer books of the Company shall be closed, the person or persons in whose name the certificate or certificates for such shares are to be
issued shall be deemed to have become the record Holder thereof for all purposes on the next day on which such stock transfer books are open, but such conversion shall be at the Conversion Price in effect on the date upon which such Securities shall
be surrendered.



No payment or adjustment will be made for
dividends or distributions on Common Stock issued upon conversion of a Security.



Except as otherwise provided in this paragraph, no payment or adjustment will be made for accrued interest including Additional Interest, if any, on a converted Security. Securities surrendered for conversion (in
whole or in part) during the period from the close of business on any record date to the opening of business on the next succeeding Interest Payment Date (excluding Securities or portions thereof presented for purchase upon a Redemption Date, a
Change of Control Purchase Date or an Optional Purchase Date during the period beginning at the close of business on a record date and ending at the opening of business on the first Business Day after the next succeeding Interest Payment Date, or if
such interest payment date is not a Business Day, the second such Business Day) shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such interest payment date on the principal amount
of such Security then being converted, and such interest and Additional Interest, if any, shall be payable to the registered Holder notwithstanding the conversion of such Security, subject to the provisions of this Indenture relating to the payment
of defaulted interest by the Company. If the Company Defaults in the payment of interest payable on such Interest Payment Date, the Company shall promptly repay such funds to such Holder.



Nothing in this Section shall affect the right of a Holder in whose name any Security is registered at the close of business
on a record date to receive the interest payable on such Security on the related Interest Payment Date in accordance with the terms of this Indenture and the Securities. 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.



For the avoidance of doubt, settlement in Cash or Cash and shares of Common Stock, for any conversion of a Security shall be on the first Business Day following the final day of the Cash Settlement Averaging Period.
Settlement solely in shares of Common Stock, for any



35



---

conversion of a Security shall be on the third Business day following the final day of the Cash Settlement Notice Period.



Section 4.3 Fractional Shares.



The Company will not issue fractional shares of Common Stock upon conversion
of Securities. In lieu thereof, the Company will pay an amount in Cash for the current market value of the fractional shares. The current market value of a fractional share shall be determined (calculated to the nearest 1/1000thof a share) by multiplying the Closing Price (determined as set forth in Section 4.6(e) hereof) of the Common Stock on the
Trading Day immediately prior to the Conversion Date by such fractional share and rounding the product to the nearest whole cent.



Section 4.4 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 certificate representing
the Common Stock being issued in a name other than the Holders name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holders name. Nothing
herein shall preclude any tax withholding required by law or regulation.



Section 4.5 Company to Reserve 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 into shares of Common Stock.



All
shares of Common Stock delivered upon conversion of the Securities shall be duly authorized, validly issued, fully paid and nonassessable 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 on the NNM or other
over-the-counter market or such other market on which the Common Stock is then listed or quoted; provided, however, that if rules of such automated quotation system or exchange permit the Company to defer the listing of such Common
Stock until the first conversion of the Securities into Common Stock in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Securities in accordance with the requirements
of such automated quotation system or exchange at such time. Any Common Stock issued upon conversion of a Security hereunder which at the time of conversion was a Restricted Security will also be a Restricted Security.

Section 4.6 Adjustment of Conversion Price.



The conversion price as stated in paragraph 8 of the Securities (the Conversion Price) shall be adjusted
from time to time by the Company as follows (without duplication):



(a) In case the Company shall (i) pay a dividend on its Common Stock in shares of Common Stock, (ii) make a distribution on its Common Stock in shares of Common Stock, (iii) subdivide its outstanding Common Stock into a greater number of
shares, or (iv) combine or reclassify its outstanding Common Stock into a smaller number of shares, 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 that number of shares of Common Stock which it would have owned had such Security been converted immediately prior to the record date of such event or the happening of such event, as appropriate. An adjustment made
pursuant to this subsection (a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution in the case of a dividend or distribution and shall become effective
immediately after the effective date in the case of subdivision, combination or classification.



(b) In case the Company shall issue rights or warrants to all or substantially all holders of its Common Stock entitling them (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 (or having a conversion
price per share) less than the Current Market Price per share of Common Stock (as determined in accordance with subsection (e) of this Section 4.6) on the record date for the determination of stockholders entitled to receive such rights or warrants,
the Conversion Price in effect immediately prior to the date of issuance shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to such record date by a fraction of which
the numerator shall be the number of shares of Common Stock outstanding on such record date plus the number of shares which the aggregate offering price of the total number of shares of Common Stock so offered (or the aggregate conversion price of
the convertible securities so offered, which shall be determined by multiplying the number of shares of Common Stock issuable upon conversion of such convertible securities by the conversion price per share of Common Stock pursuant to the terms of
such convertible securities) would purchase at the Current Market Price per share (as defined in subsection (e) of this Section 4.6) of Common Stock on such record date, and of which the denominator shall be the number of shares of Common Stock
outstanding on such record date plus the number of additional shares of Common Stock offered (or into which the convertible securities so offered are convertible). Such adjustment shall be made successively whenever any such rights or warrants are
issued, and shall become effective immediately after such record date. If at the end of the period during which such rights or warrants are exercisable not all such rights or warrants shall have been exercised, the adjusted Conversion Price shall be
immediately readjusted to what it would have been based upon 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).



(c) In case the Company shall distribute to all or substantially all of the
holders of its Common Stock any shares of capital stock of the Company (other than Common



37



---

Stock), evidences of indebtedness or other non-Cash assets (including securities of any person other than the Company but excluding (1) dividends or
distributions paid exclusively in Cash or (2) dividends or distributions referred to in subsection (a) of this Section 4.6), or shall distribute to all or substantially all of the holders of its Common Stock rights or warrants to subscribe for or
purchase any of its securities (excluding those rights and warrants referred to in subsection (b) of this Section 4.6 and also excluding the distribution of rights to all holders of Common Stock pursuant to a Rights Plan (as defined below)), then in
each such case the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the current Conversion Price by a fraction of which the numerator shall be the Current Market Price per share (as defined in
subsection (e) of this Section 4.6) of the Common Stock on the record date mentioned below less the fair market value on such record date (as determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market
value and which shall be evidenced by an Officers Certificate delivered to the Trustee) of the portion of the capital stock, evidences of indebtedness or other non-Cash assets so distributed or of such rights or warrants applicable to one
share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the record date), and of which the denominator shall be the Current Market Price per share (as defined in subsection (e) of this Section 4.6) of
the Common Stock on such record date. Such adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of shareholders entitled to receive such
distribution. In the event that a record date for any dividend or distribution referred to in this subsection (c) occurs, but such dividend or distribution is not then paid or made, the Conversion Price shall again be adjusted to be the Conversion
Price which would have been in effect if such dividend or distribution had not been declared.



In the event the then fair market value (as so determined) of the portion of the capital stock, evidences of indebtedness or other non-Cash assets so distributed or of such rights or warrants applicable to one share
of Common Stock is equal to or greater than the Current Market Price per share of the Common Stock on such record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of a Security shall have the right to
receive upon conversion the amount of capital stock, evidences of indebtedness or other non-Cash assets so distributed or of such rights or warrants such holder would have received had such holder converted each Security on such record date. If the
Board of Directors determines the fair market value of any distribution for purposes of this Section 4.6(c) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the
same period used in computing the Current Market Price of the Common Stock.



With respect to rights to purchase preferred shares or shares of Common Stock issued pursuant to any rights that may be issued or distributed pursuant to any shareholders rights plan that the Company implements after
the date of this Indenture (any rights that may be issued pursuant to any such future rights plan being referred to as a Rights Plan), upon conversion of the Securities into Common Stock, to the extent that such Rights Plan is in
effect upon such conversion, each Holder of Securities will receive, in addition to the Common Stock, the rights described therein (whether or not the rights have separated from the Common Stock at the time of conversion), unless such Holder is
specifically excluded from securing such rights by any Rights Plan. Any distribution of rights or warrants pursuant to the Rights Plan in accordance



38



---

with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute a distribution of rights or warrants pursuant to
this Section 4.6(c).



Rights or warrants, other than rights
issued pursuant to a Rights Plan, 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 or warrants, until the occurrence of a specified event or events (Trigger Event): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of
future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.6 (and no adjustment to the Conversion Price under this Section 4.6 will be required) until the occurrence of the earliest Trigger Event,
whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Price shall be made in accordance with this Section 4.6(c). If any such right or warrant is subject to
events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of
distribution and record date with respect to new rights or warrants (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution or deemed
distribution of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the
Conversion Price under this Section 4.6 was made, (1) in the case of any such rights or warrants 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 or holders of Common Stock with
respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants which shall have
expired or been terminated without exercise by any holders thereof, the Conversion Price shall be readjusted as if such rights and warrants had not been issued.



(i) In case the Company shall, by dividend or otherwise, at any time make a distribution (a
Triggering Distribution) to all or substantially all holders of its Common Stock consisting exclusively of Cash on the Business Day (the Determination Date) immediately preceding the day on which such Triggering
Distribution is declared by the Company multiplied by the number of shares of Common Stock outstanding on the Determination Date (excluding shares held in the treasury of the Company), the Conversion Price shall be reduced so that the same shall
equal the price determined by multiplying such Conversion Price in effect immediately prior to the Determination Date by a fraction of which the numerator shall be the Current Market Price per share of the Common Stock (as determined in accordance
with subsection (e) of this Section 4.6) on the Determination Date less the quotient of (y) the sum of the aggregate amount of Cash so distributed, paid or payable pursuant to the Triggering Distribution divided by (z) the number of shares of Common
Stock outstanding on the Determination Date and the denominator shall be such Current Market Price per share of the Common Stock (as determined in accordance with subsection (e) of this Section 4.6) on the



39



---

Determination Date, such reduction to become effective immediately prior to the opening of business on the day following the date on which the Triggering
Distribution is paid.



(ii) In the event any
tender offer or exchange offer made by the Company or any of its Subsidiaries for Common Stock shall expire and the Company shall pay for Purchased Shares (as defined below) an aggregate consideration in an amount (determined as the sum of the
aggregate amount of Cash consideration and the aggregate fair market value (as determined by the Board of Directors, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers Certificate delivered to
the Trustee thereof) of any other consideration) that, as of the last time (the Expiration Time) tenders or exchanges may be made pursuant to such tender or exchange offer exceeds 110% of the current Market Price per share of
Common Stock at the Expiration Time, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the last date tenders or
exchanges may be made pursuant to such tender or exchange offer (the Expiration Date) by a fraction of which the numerator shall be the product of the number of shares of Common Stock outstanding (including Purchased Shares but
excluding any shares held in the treasury of the Company) at the Expiration Time multiplied by the Current Market Price per share of the Common Stock (as determined in accordance with subsection (e) of this Section 4.6) on the Trading Day next
succeeding the Expiration Date and the denominator shall be the sum of (x) the aggregate consideration (determined as aforesaid) payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender offer) of all
shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the Purchased Shares) and (y) the product of the number of shares of Common Stock
outstanding (less any Purchased Shares and excluding any shares held in the treasury of the Company) at the Expiration Time and the Current Market Price per share of Common Stock (as determined in accordance with subsection (e) of this Section 4.6)
on the Trading Day next succeeding the Expiration Date, such reduction to become effective immediately prior to the opening of business on the day following the Expiration Date. In the event that the Company is obligated to purchase shares pursuant
to any such tender offer, but the Company is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which
would have been in effect based upon the number of shares actually purchased. If the application of this Section 4.6(c)(ii) to any tender offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer
under this Section 4.6(c)(ii).



(iii) For
purposes of this Section 4.6(c), the term tender offer shall mean and include both tender offers and exchange offers, all references to purchases of shares in tender offers (and all similar references) shall mean and include
both the purchase of shares in tender offers and the acquisition of shares pursuant to exchange offers, and all references to tendered shares (and all similar references) shall mean and include shares tendered in both tender offers and
exchange offers.



(d) After any adjustment to the Conversion
Price is made in accordance with Section 4.6(c)(i) or (ii), no distribution or consideration (including the Triggering Distribution) that is taken into account in making such adjustment shall again be taken into account for any future or other
adjustments made in accordance with Section 4.6.



40



---

(e) For the purpose of any computation under subsections (b) and (c) of this Section 4.6, the current
market price (the Current Market Price) per share of Common Stock on any date shall be deemed to be the average of the daily closing prices for the 30 consecutive Trading Days commencing 10 Trading Days before (i) the
Determination Date or the Expiration Date, as the case may be, with respect to distributions or tender offers under subsection (c) of this Section 4.6 or (ii) the record date with respect to distributions, issuances or other events requiring such
computation under subsection (b) or (c) of this Section 4.6. The closing price (the Closing Price) for each day shall be the last reported sales price or, in case no such reported sale takes place on such date, the average of the
reported closing bid and asked prices in either case on The American Stock Exchange (the AMEX) or, if the Common Stock is not listed or admitted to trading on the AMEX, the Nasdaq National Market (the NNM) or
any other principal national securities exchange on which the Common Stock is listed or admitted to trading or, if not listed or admitted to trading on the AMEX, the NNM or any other national securities exchange, the last reported sales price of the
Common Stock as quoted on NNM or, in case no reported sales takes place, the average of the closing bid and asked prices as quoted on NNM or any comparable system or, if the Common Stock is not quoted on NNM or any comparable system, the closing
sales price or, in case no reported sale takes place, the average of the closing bid and asked prices, as furnished by any two members of the National Association of Securities Dealers, Inc. selected from time to time by the Company for that
purpose. If no such prices are available, the Current Market Price per share shall be the fair value of a share of Common Stock as determined by the Board of Directors (which shall be evidenced by an Officers Certificate delivered to the
Trustee).



(f) In any case in which this Section 4.6 shall
require that an adjustment be made following a record date or a Determination Date or Expiration Date, as the case may be, established for purposes of this Section 4.6, 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 4.10) issuing to the Holder of any Security converted after such record date or Determination Date or Expiration 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 prepared by the Company of the right to receive such shares. If any distribution in respect of which an
adjustment to the Conversion Price is required to be made as of the record date or Determination Date or Expiration Date therefor is not thereafter made or paid by the Company for any reason, the Conversion Price shall be readjusted to the
Conversion Price which would then be in effect if such record date had not been fixed or such effective date or Determination Date or Expiration Date had not occurred.



Section 4.7 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 4.7 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All



41



---

calculations under this Article 4 shall be made to the nearest cent or to the nearest one thousandth of a share, as the case may be.



No adjustment need be made for issuances of Common Stock pursuant to a
Company plan for reinvestment of dividends or interest or for a change in the par value or a change to no par value of the Common Stock.



Section 4.8Other Adjustments.



(a) In the event that, as a result of an adjustment made pursuant to Section 4.6 hereof, the Holder of any Security
thereafter surrendered for conversion shall become entitled to receive any shares of Capital Stock of the Company other than Common Stock, thereafter the Conversion Price of such other shares so receivable upon conversion of any Security 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 4.



(b) In the event that shares of Common Stock are not delivered after the expiration of any of the rights or warrants
referred to in Sections 4.6(b) and (c) hereof, the Conversion Price shall be readjusted to the Conversion Price which would otherwise be in effect had the adjustment made upon the issuance of such rights or warrants been made on the basis of
delivery of only the number of shares of Common Stock actually delivered.



(c) Except as set forth in this Article 4, the Company shall not adjust the Conversion Price for (i) the issuance of its Common Stock or any securities convertible into or exchangeable therefor or (ii) the right to
purchase its Common Stock or any securities convertible or exchangeable therefor.



Section 4.9 Adjustment for Tax Purposes.



The Company shall be entitled to make such reductions in the Conversion Price, in addition to those required by Section 4.6, as it in its discretion shall determine to be advisable in order that any stock dividends, subdivisions of shares,
distributions of rights to purchase stock or securities or distributions of securities convertible into or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable.



Section 4.10 Notice of Adjustment.



Whenever the Conversion Price or conversion privilege is adjusted as herein
provided, 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. Unless and until the
Trustee shall receive an Officers Certificate setting forth an adjustment of the Conversion Price, the Trustee may assume without inquiry that the Conversion Price has not been adjusted and that the last Conversion Price of which it has
knowledge remains in effect.



42

Section 4.11 Notice of Certain Transactions.



In the event that:



(a) the Company takes any action which would require an adjustment in the Conversion Price;



(b) the Company consolidates or merges with, or transfers all or substantially all of its property and assets to, another
corporation and shareholders of the Company must approve the transaction; or



(c) there is a dissolution or liquidation of the Company,



the Company shall mail to Holders and file with the Trustee a notice stating the proposed record or effective date, as the case may be, of such event. The Company shall mail the notice at least ten days before such
date. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (a), (b) or (c) of this Section 4.11.



Section 4.12 Effect of Reclassification, Consolidation, Merger or Sale on Conversion Privilege.



If any of the following shall occur, namely: (a) any reclassification or
change of shares of Common Stock issuable upon conversion of the Securities (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, or any other change
for which an adjustment is provided in Section 4.6); (b) any consolidation or merger or combination 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 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) in, outstanding shares of Common Stock; or (c) any sale or conveyance as
an entirety or substantially as an entirety of the property and assets of the Company, directly or indirectly, to any Person, then the Company, or such successor, purchasing or transferee corporation, as the case may be, shall, as a condition
precedent to such reclassification, change, combination, consolidation, merger, 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 stock and other securities and property (including Cash) receivable upon such reclassification, change, combination, consolidation, merger, 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, combination, consolidation, merger, sale or conveyance. Such supplemental indenture shall provide for adjustments of the
Conversion Price which shall be as nearly equivalent, as the Board of Directors shall reasonably consider in good faith to be practicable, to the adjustments of the Conversion Price provided for in this Article 4. If, in the case of any such
consolidation, merger, combination, sale or conveyance, the stock or other securities and property (including Cash) receivable thereupon by a holder of Common Stock include shares of stock or other securities and property of a person other than the
successor, purchasing or transferee corporation, as the case may be, in such consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be



43



---

executed by such other person and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of
Directors shall reasonably consider necessary by reason of the foregoing. The provisions of this Section 4.12 shall similarly apply to successive reclassifications, changes, combinations, consolidations, mergers, sales or conveyances.



In the event the Company shall execute a supplemental indenture pursuant to
this Section 4.12, the Company shall promptly file with the Trustee an Officers Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or other securities or property (including Cash) receivable by Holders of
the Securities upon the conversion of their Securities after any such reclassification, change, combination, consolidation, merger, sale or conveyance, any adjustment to be made with respect thereto and that all conditions precedent have been
complied with, and shall promptly mail notice thereof to all Holders.



Section 4.13 Trustees Disclaimer.



The Trustee shall have no duty to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of any such
adjustment, and shall be protected in relying upon, an Officers Certificate including the Officers Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.10. The Trustee makes no
representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the Companys failure to comply with any provisions of this Article 4.



The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed pursuant to Section 4.12, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers Certificate
with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.12.



Section 4.14 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 days and if the reduction is irrevocable during the period if the Companys Board of
Directors determines that such reduction would be in the best interest of the Company or to avoid or diminish income tax to holders of shares of Common Stock in connection with a dividend or distribution of stock or similar event, and the Company
provides 15 days prior notice of any reduction in the Conversion Price; provided, however, that in no event may the Company reduce the Conversion Price to be less than the par value of a share of Common Stock or require shareholder
approval under AMEX rules in effect at the time of the reduction, unless the requisite number of the Companys shareholders shall have duly approved such reduction.



Section 4.15 Payment of Cash in Lieu of Common Stock.



If a Holder elects to convert all or any portion of a Security into shares of Common Stock as set forth in this Section 4
and the Company receives such Holders Conversion Notice on or prior to the day that is 20 days prior to the Final Maturity Date (the



44



---

Final Notice Date), the Company may choose to satisfy all or any portion of its conversion obligation (the Conversion
Obligation) in Cash. Upon such election, the Company will notify such Holder through the Trustee of the dollar amount to be satisfied in Cash (which must be expressed either as 100% of the Conversion Obligation or as a fixed dollar amount)
at any time on or before the date that is two Business Days following receipt of written notice of conversion as specified in Section 4.2 (such period, the Cash Settlement Notice Period). If the Company elects to pay Cash for any
portion of the shares otherwise issuable to the Holder, the Holder may retract the Conversion Notice at any time during the two Business Day period beginning on the day after the final day of the Cash Settlement Notice Period (a Conversion
Retraction Period); no such retraction can be made (and a Conversion Notice shall be irrevocable) if the Company does not elect to deliver Cash in lieu of shares (other than Cash in lieu of fractional shares). If the Conversion Notice has
not been retracted, then settlement in Cash or Cash and shares of Common Stock, will occur on the Business Day following the final day of the five Trading Day period beginning on the first Trading Day after the final day of the Conversion Retraction
Period (the Cash Settlement Averaging Period). Settlement amounts will be computed as follows:



(a) if the Company elects to satisfy the entire Conversion Obligation in shares of Common Stock, the Company will deliver to such Holder a number of
shares equal to (i) the aggregate original principal amount at maturity of the Securities to be converted divided by 1,000, multiplied by (ii) the Conversion Rate;



(b) if the Company elects to satisfy the entire Conversion Obligation in Cash, the Company will deliver to such Holder Cash
in an amount equal to the product of:



(i) a
number equal to (x) the aggregate original principal of Securities to be converted divided by 1,000, multiplied by (y) the Conversion Rate, and



(ii) the average Closing Price of the Common Stock during the Cash Settlement Averaging Period; and



(iii) if the Company elects to satisfy a fixed portion
(other than 100%) of the Conversion Obligation in Cash (the Partial Cash Amount), the Company will deliver to such Holder the Partial Cash Amount and a number of shares equal to (1) the Cash settlement amount set forth in clause
(b) above minus such Partial Cash Amount divided by (2) the average of the Closing Prices of the Common Stock during the Cash Settlement Averaging Period.



Notwithstanding the foregoing, a Security in respect of which a Holder has delivered a Change of Control Purchase Notice exercising such Holders
option to require the Company to repurchase such Security may be converted as described in this Section 4.15 only if such notice of exercise is withdrawn as required in Section 3.7(e) hereof.



If a Holder elects to convert all or any portion of a Security into shares of
Common Stock as set forth in Section 4.1 and the Company receives such Conversion Notice after the Final Notice Date, if the Company chooses to satisfy all or any portion of the Conversion Obligation in Cash, the Company will have previously
notified the Holders through the Trustee of the dollar amount to be satisfied in Cash at any time on or before the Final Notice Date. Upon such election, the Company will have notified the Holders through the Trustee of



45



---

the dollar amount to be satisfied in Cash (which must be expressed either as 100% or as a fixed dollar amount) at any time on or before the Final Notice
Date. Settlement amounts and settlement dates will be computed in the same manner as set forth above except that the Cash Settlement Averaging Period shall be the five Trading Day period beginning on the day after receipt of the Conversion Notice
(or in the event the Company receives the Conversion Notice on the Business Day prior to the Final Maturity Date, the five Trading Day period beginning on the day after the Final Maturity Date). Settlement in Cash or Cash and shares of Common Stock,
will occur on the Business Day following the final day of such Cash Settlement Averaging Period. Settlements solely in shares of Common Stock will occur on the third Business Day following the final day of the Cash Settlement Notice Period.



ARTICLE V.

SUBORDINATION



Section 5.1 Agreement of Subordination.



The Company agrees and each Securityholder by accepting a Security agrees that the payment of the principal of and interest including Additional Interest,
if any, on all Securities (including, but not limited to, the Redemption Price with respect to the Securities called for redemption, or the Change of Control Purchase Price or Optional Purchase Price with respect to the Securities subject to
purchase in accordance with Article 3 of this Indenture) issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior payment in full in Cash or payment satisfactory to
the holders of Senior Indebtedness of all Senior Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred and that the subordination is for the benefit of the holders of the Senior Indebtedness.



No provision of this Article 5 shall prevent the occurrence of any Default or
Event of Default hereunder.



Section 5.2 Payments to Holders.



No payment shall be made with respect to the principal of
or interest including Additional Interest, if any, on the Securities (including, but not limited to, the Redemption Price with respect to the Securities called for redemption or the Change of Control Purchase Price or Optional Purchase Price with
respect to the Securities subject to purchase in accordance with Article 3 of this Indenture), except payments and distributions made by the Trustee as permitted by Section 5.11, if:



(a) a Default in the payment of principal, interest, rent or other obligations due on any Designated Senior Indebtedness
occurs and is continuing (or, in the case of Designated Senior Indebtedness for which there is a period of grace, in the event of such a Default that continues beyond the period of grace, if any, specified in the instrument or lease evidencing such
Designated Senior Indebtedness); or



(b) a Default, other than
a payment Default, on any Designated Senior Indebtedness occurs and is continuing that then permits holders of such Designated Senior Indebtedness to accelerate its maturity and the Trustee receives a notice of the Default (a



46



---

Payment Blockage Notice) from a Representative or holder of Designated Senior Indebtedness or the Company.



Subject to the provisions of Section 5.5, if the Trustee receives any Payment
Blockage Notice pursuant to clause (b) above, no subsequent Payment Blockage Notice shall be effective for purposes of this Section unless and until at least 365 days shall have elapsed since the initial effectiveness of the immediately prior
Payment Blockage Notice and all scheduled payments on the Securities that have come due and payable 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 to the
Trustee (unless such Default was waived, cured or otherwise ceased to exist and thereafter subsequently reoccurred) shall be, or be made, the basis for a subsequent Payment Blockage Notice.



The Company shall resume payments on and distributions in respect of the
Securities upon the earlier of:



(i) in the
case of a Default referred to in clause (a) above, the date upon which the Default is cured or waived or ceases to exist, or



(ii) in the case of a Default referred to in clause (b) above, the earlier of the date on which such Default is cured or waived or ceases
to exist or 179 days after the date on which the applicable Payment Blockage Notice is received, if the maturity of such Designated Senior Indebtedness has not been accelerated, unless this Article 5 otherwise prohibits the payment or distribution
at the time of such payment or distribution.



Section 5.3 Liquidation;
Dissolution; Bankruptcy.



Upon any payment by the
Company, or distribution of assets of the Company of any kind or character, whether in Cash, property or securities, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Company (whether voluntary or involuntary)
or in bankruptcy, insolvency, receivership or similar proceedings relating to the Company or its property or in an assignment for the benefit of creditors or any marshalling of the Companys assets and liabilities, all amounts due or to become
due upon all Senior Indebtedness shall first be paid in full in Cash, or other payments satisfactory to the holders of Senior Indebtedness before any payment is made on account of the principal of or interest including Additional Interest, if any,
on the Securities (including, but not limited to, the Redemption Price with respect to Securities called for redemption or the Change of Control Purchase Price or Optional Purchase Price with respect to the Securities subject to purchase in
accordance with Article 3 of this Indenture); and upon any such dissolution or winding-up or liquidation or reorganization of the Company or bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, or distribution of
assets of the Company of any kind or character, whether in Cash, property or securities, to which the Holders of the Securities or the Trustee would be entitled, except for the provision of this Article 5, shall (except as aforesaid) be paid by the
Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders of the Securities or by the Trustee under this Indenture if received by them or it, directly to the
holders of Senior Indebtedness (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders,



47



---

or as otherwise required by law or a court order) or their representative or representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full in Cash, or other payment satisfactory to the holders of Senior
Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness, before any payment or distribution is made to the Holders of the Securities or to the Trustee.



For purposes of this Article 5, the words, Cash, property or
securities shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided in this Article 5 with respect to the Securities to the payment of all Senior Indebtedness which may at the time be outstanding; provided that (i) the Senior Indebtedness is assumed by the new
corporation, if any, resulting from any reorganization or readjustment, and (ii) the rights of the holders of Senior Indebtedness (other than leases which are not assumed by the Company or the new corporation, as the case may be) are not, without
the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance,
transfer or lease of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in Article 7 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the
purposes of this Section 5.3 if such other corporation shall, as a part of such consolidation, merger, conveyance, transfer or lease, comply with the conditions stated in Article 7.



Section 5.4 Acceleration of the Securities.



In the event of the acceleration of the Securities because of an Event of Default, no payment or distribution shall be made
to the Trustee or any Holder of Securities in respect of the principal of or interest including Additional Interest, if any, on the Securities by the Company (including, but not limited to, the Redemption Price with respect to the Securities called
for redemption or the Change of Control Purchase Price or the Optional Purchase Price with respect to the Securities subject to purchase in accordance with Article 3 of this Indenture), except payments and distributions made by the Trustee as
permitted by Section 5.5, until all Senior Indebtedness has been paid in full in Cash or other payment satisfactory to the holders of Senior Indebtedness or such acceleration is rescinded in accordance with the terms of this Indenture. If payment of
the Securities is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Indebtedness of such acceleration.



Section 5.5 When Distribution Must Be Paid Over.



In the event that, notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character, whether in
Cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Trustee or the Holders of the Securities before all Senior Indebtedness is paid in full, in Cash or
other payment satisfactory to the holders of Senior Indebtedness, or provision is made for such payment thereof in accordance with its terms in Cash



48



---

or other payment satisfactory to the holders of Senior Indebtedness, such payment or distribution shall be held in trust for the benefit of and shall be paid
over or delivered to the holders of Senior Indebtedness or their Representative or Representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their
respective interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full, in Cash or other payment satisfactory to the
holders of Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness.



Nothing in these Sections 5.2 through 5.5 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 9.7. These Sections 5.2
through 5.5 shall be subject to the further provisions of Section 5.10.



Section 5.6 Subrogation of Securities.



After payment in full, in Cash or other payment satisfactory to the holders of Senior Indebtedness, of all Senior Indebtedness, the rights of the Holders of the Securities shall be subrogated (equally and ratably with all other Indebtedness
pari passu with the Securities), to the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article 5, 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 and interest including Additional Interest, if any, on the Securities shall be paid in full in Cash or other payment
satisfactory to the Holders of the Securities; and, for the purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any Cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article 5, and no payment pursuant to the provisions of this Article 5, to or for the benefit of the holders of Senior Indebtedness by Holders of the Securities or the Trustee, shall, as
between the Company, its creditors other than holders of Senior Indebtedness, and the Holders of the Securities, be deemed to be a payment by the Company to or on account of the Senior Indebtedness; and no payments or distributions of Cash, property
or securities to or for the benefit of the Holders of the Securities pursuant to the subrogation provisions of this Article 5, which would otherwise have been paid to the holders of Senior Indebtedness, shall be deemed to be a payment by the Company
to or for the account of the Securities. It is understood that the provisions of this Article 5 are, and are intended solely for, the purposes of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of the
Senior Indebtedness, on the other hand.



Section 5.7 Related Rights.



Nothing contained in this Article 5 or elsewhere in this
Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Indebtedness, and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional,
to pay to the Holders of the Securities the principal of and interest including Additional Interest, if any, on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the



49



---

relative rights of the Holders of the Securities and creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything herein or
therein prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon Default under this Indenture, subject to the rights, if any, under this Article 5 of the holders of Senior Indebtedness
in respect of Cash, property or securities of the Company received upon the exercise of any such remedy.



Section 5.8 Certain Conversions Deemed Payment.



For the purposes of this Article 5 only, (1) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article 4 shall not be deemed to constitute a payment or distribution on
account of the principal of or interest on Securities or on account of the purchase or other acquisition of Securities, and (2) the payment, issuance or delivery of Cash (except in satisfaction of fractional shares pursuant to Section 4.3), property
or securities (other than junior securities) upon conversion of a Security shall be deemed to constitute payment on account of the principal of such Security. For the purposes of this Section 5.8, the term junior securities means (a)
shares of any stock of any class of the Company, or (b) securities of the Company which are subordinated in right of payment to all Senior Indebtedness which may be outstanding at the time of issuance or delivery of such securities to substantially
the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article. Nothing contained in this Article 5 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the
Company, its creditors other than holders of Senior Indebtedness and the Holders, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article 4.



Section 5.9 Distribution Notice to Representative.



Upon any payment or distribution of assets of the Company referred to in
this Article 5, the Trustee, subject to the provisions of Section 9.1 hereof, and the Holders of the Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such bankruptcy, dissolution,
winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of
the Securities, 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 and all other facts
pertinent thereto or to this Article 5.



Section 5.10 Authorization to
Effect Subordination.



Each Holder of a Security by
the Holders acceptance thereof authorizes and directs the Trustee on the Holders behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 5 and appoints the Trustee to act
as the Holders attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 8.9 hereof at least 30 days before the
expiration of the time to file such claim, the holders of any Senior Indebtedness or their representatives are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Securities.

Section 5.11 Notice to Trustee.



The Company shall give prompt written notice in the form of an Officers Certificate to a Trust Officer of the Trustee
and to any Paying Agent of any fact known to the Company which would prohibit the making of any payment of monies to or by the Trustee or any Paying Agent in respect of the Securities pursuant to the provisions of this Article 5. Notwithstanding the
provisions of this Article 5 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article 5, unless and until a Trust Officer of the Trustee shall have received written notice thereof at the Corporate Trust Office from the Company (in the form of an Officers Certificate) or a
Representative or a holder or holders of Senior Indebtedness or otherwise have actual knowledge thereof; and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 9.1, shall be entitled in all respects to
assume that no such facts exist; provided that if on a date not less than one Business Day prior to the date upon which by the terms hereof any such monies may become payable for any purpose (including, without limitation, the payment of the
principal of or interest and Additional Interest, if any, on any Security) the Trustee shall not have received, with respect to such monies, the notice provided for in this Section 5.11, 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, subject to the provisions
of Section 9.1, shall be entitled to rely on the delivery to it of a written notice by a Representative or 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 Representative or 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 5, 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 5, 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.



Section 5.12 Trustees Relation to Senior Indebtedness.



The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 5 in respect of any Senior Indebtedness at any time
held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in Section 9.11 or elsewhere in this Indenture shall deprive the Trustee of any of its rights as such holder.



With respect to the holders of Senior Indebtedness, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are specifically set forth in this Article 5, and no implied covenants or obligations with respect to the holders of Senior



51



---

Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness and, subject to the provisions of Section 9.1, the Trustee shall not be liable to any holder of Senior Indebtedness if it shall pay over or deliver to Holders of Securities, the Company or any other person money or assets to which any
holder of Senior Indebtedness shall be entitled by virtue of this Article 5 or otherwise.



Section 5.13 No Impairment of Subordination.



No right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the
Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or
otherwise be charged with.



Section 5.14 Article Applicable to Paying
Agents.



If at any time any Paying Agent other than
the Trustee shall have been appointed by the Company and be then acting hereunder, the term Trustee as used in this Article shall (unless the context otherwise requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee; provided, however, that the first paragraph of Section 5.10 shall not apply to the Company
or any Affiliate of the Company if it or such Affiliate acts as Paying Agent.



Section 5.15 Senior Indebtedness Entitled to Rely.



The holders of Senior Indebtedness (including, without limitation, Designated Senior Indebtedness) shall have the right to rely upon this Article 5, and no amendment or modification of the provisions contained herein
shall diminish the rights of the holders of Senior Indebtedness outstanding at the time such amendment or modification goes into effect unless such holders shall have agreed in writing thereto.



Section 5.16 Agreement to Subordinate Unaffected.



The provisions of this Article 5 shall remain in full force and effect
irrespective of (a) any amendment, modification, or supplement of, or any waiver or consent to, any of the terms of any Senior Indebtedness or the agreement or instrument governing any Senior Indebtedness, (b) the release or non-perfection of any
collateral securing any Senior Indebtedness or (c) the manner of sale or other disposition of the collateral securing any Senior Indebtedness or the application of the proceeds upon such sale.

The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or

ARTICLE VIII.

DEFAULT AND REMEDIES



Section 8.1 Events of Default.



An Event of Default shall occur if:



(a) the Company defaults in the payment of any principal of any Security when
the same becomes due and payable, whether or not such payment shall be prohibited by the provisions of Article 5 hereof;



(b) the Company defaults in the payment of any interest including Additional Interest, if any, payable on any Security when the same becomes due and
payable and the Default continues for a period of 30 days, whether or not such payment shall be prohibited by the provisions of Article 5 hereof;



(c) the Company fails to comply with any of its other agreements or covenants contained in the Securities or this Indenture and such failure continues for
60 days after a Notice of Default (defined below);



(d) the

(e) the Company fails to issue Cash, Common Stock or a combination thereof upon conversion of Securities by a Holder in accordance with the provisions of
Article 4 hereof;



56



---

(f) the Company fails to provide notice of a Change of Control when required by Section 3.7 hereof;



(g) any indebtedness under any bond, debenture, note or other
evidence of indebtedness for money borrowed by the Company or any Significant Subsidiary or under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed
by the Company or any Significant Subsidiary (an Instrument) with a principal amount then outstanding in excess of U.S. $10.0 million, whether such indebtedness now exists or shall hereafter be created, is not paid at final
maturity of the Instrument (either at its stated maturity or upon acceleration thereof), and such indebtedness is not discharged, or such acceleration is not rescinded or annulled, within a period of 30 days after there shall have been given, by
registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Securities then outstanding a written notice specifying such Default and requiring the
Company to cause such indebtedness to be discharged or cause such Default to be cured or waived or such acceleration to be rescinded or annulled and stating that such notice is a Notice of Default hereunder; or



(h) the Company or any Significant Subsidiary, pursuant to or within the
meaning of any Bankruptcy Law:



(i) commences
a voluntary case or proceeding;



(ii) consents
to the entry of an order for relief against it in an involuntary case or proceeding;



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



(iv) makes a general assignment for the benefit of its
creditors; or



(v) a court of competent
jurisdiction enters an order or decree under any Bankruptcy Law that:

| | --- | -----------------------------------------------------------------------------------------------------



| | (2) | appoints a Custodian of the Company or any Significant Subsidiary or for all or substantially all of the property of the Company or any Significant Subsidiary; or
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (3) | orders the liquidation of the Company or any Significant Subsidiary.
| | --- | --------------------------------------------------------------------



and in each case the order or decree remains unstayed and in effect for 60 consecutive days.



The term Bankruptcy Law means Title 11 of the United States Code (or any successor thereto) or any
similar federal or state law for the relief of debtors. The term



57



---

Custodian means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law.



A default under clause (c) above is not an Event of Default until the Trustee
notifies the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee, in writing of the default, and the Company does not cure the default within 60 days after
receipt of such notice.



The notice given pursuant to this
Section 8.1 must specify the Default, demand that it be remedied and state that the notice is a Notice of Default. When any Default under this Section 8.1 is cured, it ceases.



Section 8.2 Acceleration.



If an Event of Default (other than an Event of Default specified in clause (g) or (h) of Section 8.1) occurs and is continuing, the Trustee may, by notice
to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare all unpaid principal, together with all accrued and unpaid interest including
Additional Interest, if any, to the date of acceleration on the Securities then outstanding (if not then due and payable) to be due and payable upon any such declaration, and the same shall become and be immediately due and payable. If an Event of
Default specified in clause (g) or (h) of Section 8.1 occurs, all unpaid principal, together with all accrued and unpaid interest including Additional Interest, if any, of the Securities then outstanding shall ipso facto become and be immediately
due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate 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 the Securities which has become due solely by such declaration of acceleration, have been cured or waived; (b) to the extent the payment of such
interest is lawful, interest (calculated at the rate per annum borne by the Securities) on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; (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 9.7 have been made. No such rescission shall affect any subsequent
Default or impair any right consequent thereto.



Section 8.3 Other
Remedies.



If an Event of Default occurs and is
continuing, the Trustee may, but shall not be obligated to, pursue any available remedy by proceeding at law or in equity to collect the payment of the principal of or interest and Additional Interest, if any, on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.



The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any 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



58



---

Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.



Section 8.4 Waiver of Defaults and Events of Default.



Subject to Sections 8.7 and 10.2, the Holders of a majority of the aggregate
principal amount of the Securities then outstanding by notice to the Trustee may waive an existing Default or Event of Default and its consequence, except a Default or Event of Default in the payment of the principal of or interest and Additional
Interest, if any, on any Security (including payment of the Change of Control Purchase Price or Optional Purchase Price in connection with a Change of Control Offer or Optional Purchase Offer, as the case may be), a failure by the Company to convert
any Securities into Cash, Common Stock or any combination thereof or any Default or Event of Default in respect of any provision of this Indenture or the Securities which, under Section 10.2, cannot be modified or amended without the consent of the
Holder of each Security affected. When a Default or Event of Default is waived, it is cured and ceases.



Section 8.5 Control by Majority.



The Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any
trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder or the Trustee, or that may
involve the Trustee in personal liability unless the Trustee is offered reasonable indemnity satisfactory to it; provided, however, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with
such direction.



Section 8.6 Limitations on Suits.



A Holder may not pursue any remedy with respect to this Indenture or the
Securities (except actions for payment of overdue principal or interest or for the conversion of the Securities pursuant to Article 4) unless:



(a) the Holder gives to the Trustee written notice of a continuing Event of Default;



(b) the Holders of at least a majority in aggregate principal amount of the then outstanding Securities make a written
request to the Trustee to pursue the remedy;



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



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



59



---

(e) no direction inconsistent with such written request has been given to the Trustee during such 60 day
period by the Holders of a majority in aggregate principal amount of the Securities then outstanding.



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



Section 8.7 Rights of Holders to Receive Payment and to
Convert.



Notwithstanding any other provision of this
Indenture, the right of any Holder of a Security to receive payment of the principal of and interest and Additional Interest, if any, on the Security, on or after the respective due dates expressed in the Security and this Indenture, to convert such
Security in accordance with Article 4 and to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, is absolute and unconditional and shall not be impaired or affected without the consent of the
Holder.



Section 8.8 Collection Suit by Trustee.



If an Event of Default in the payment of principal or interest or Additional
Interest, if any, specified in clause (a) or (b) of Section 8.1 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole
amount of principal and accrued interest and Additional Interest, if any, remaining unpaid, together with, to the extent that payment of such interest is lawful, interest on overdue principal and on overdue installments of interest, in each case at
the rate per annum borne by the Securities and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel.



Section 8.9 Trustee May File Proofs of Claim.



The Trustee may file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders
allowed in any judicial proceedings relative to the Company (or any other obligor on the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any money or other property payable or deliverable on any
such claims and to distribute the same, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 9.7, and to the
extent that such payment of the reasonable compensation, expenses, disbursements and advances in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall
be deemed to authorize the Trustee to authorize or consent to, or, on behalf of



60



---

any Holder, to authorize, accept or adopt any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any
Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.



Section 8.10 Priorities.



If the Trustee collects any money pursuant to this Article 8, it shall pay out the money in the following order:



First, to the Trustee for amounts due under Section 9.7;



Second, to the holders of Senior Indebtedness to the extent required by
Article 5;



Third, to Holders for amounts due and unpaid on the
Securities for principal and interest including Additional Interest, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest including Additional Interest, if
any, respectively; and



Fourth, the balance, if any, to the
Company.



The Trustee may fix a record date and payment date
for any payment to Holders pursuant to this Section 8.10.



Section 8.11
Undertaking for Costs.



In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or
defenses made by the party litigant. This Section 8.11 does not apply to a suit made by the Trustee, a suit by a Holder pursuant to Section 8.7, or a suit by Holders of more than 25% in aggregate principal amount of the Securities then outstanding.

Section 9.5 Notice of Default or Events of Default.



If a Default or an Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to each Securityholder notice of the Default or Event of Default within 90 days after it occurs. However, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good
faith determines that withholding notice is in the interests of Securityholders, except in the case of a Default or an Event of Default in payment of the principal of or interest and Additional Interest, if any, on any Security.



Section 9.6 Reports by Trustee to Holders.



If such report is required by TIA Section 313, within 60 days after each May
15, beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Securityholder a brief report dated as of such May 15 that complies with TIA Section 313(a). The Trustee also shall comply with TIA Section 313(b)(2)

expense or indemnify it against any loss or liability incurred by it resulting from its negligence, bad faith or willful misconduct.



To secure the Companys payment obligations in this Section 9.7, the Trustee shall have a senior claim to which the Securities are hereby made
subordinate on all money or property held or collected by the Trustee, except such money or property held in trust to pay the principal of and interest, including Additional Interest, if any, on the Securities. The obligations of the Company under
this Section 9.7 shall survive the satisfaction and discharge of this Indenture or the resignation or removal of the Trustee.



When the Trustee incurs expenses or renders services after an Event of Default specified in clause (g) or (h) of Section 8.1 occurs, the expenses and the
compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. The provisions of this Section 9.7 shall survive the termination of this Indenture.

The Trustee may resign by so notifying the Company. The Holders of a

(a) the Trustee fails to comply with Section 9.10;



(b) the Trustee is adjudged a bankrupt or an insolvent;



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



(d) the Trustee 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 a successor Trustee. The resignation or removal of a Trustee shall not be effective until a successor Trustee shall have delivered the written acceptance of its appointment as
described below.



If a successor Trustee does not take office
within 45 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of 25% in principal amount of the Securities then outstanding may petition any court of competent jurisdiction for the appointment of a
successor Trustee at the expense of the Company.



If the
Trustee fails to comply with Section 9.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.



A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company.
Immediately after that, the retiring Trustee shall transfer



65



---

all property held by it as Trustee to the successor Trustee and be released from its obligations (exclusive of any liabilities that the retiring Trustee may
have incurred while acting as Trustee) hereunder, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor
Trustee shall mail notice of its succession to each Holder.



A
retiring Trustee shall not be liable for the acts or omissions of any successor Trustee after its succession.



Notwithstanding replacement of the Trustee pursuant to this Section 9.8, the Companys obligations under Section 9.7 shall continue for the benefit
of the retiring Trustee.



Section 9.9 Successor Trustee by Merger,
Etc.



If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all of its corporate trust assets (including the administration of this Indenture) to another Person, the resulting, surviving or transferee entity, without any further act, shall be the successor
Trustee, provided such transferee entity shall qualify and be eligible under Section 9.10. Such successor Trustee shall promptly mail notice of its succession to the Company and each Holder.



Section 9.10 Eligibility; Disqualification.



The Trustee shall always satisfy the requirements of paragraphs (1), (2) and
(5) of TIA Section 310(a). The Trustee (or its parent holding company) shall have a combined capital and surplus of at least $50,000,000. If at any time the Trustee shall cease to satisfy any such requirements, it shall resign immediately in the
manner and with the effect specified in this Article 9. The Trustee shall be subject to the provisions of TIA Section 310(b). Nothing herein shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph
of TIA Section 310(b).

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.

substance thereof.



After an amendment, supplement or waiver

holder of any Senior Indebtedness then outstanding unless such holder consents to the change.



Section 10.3 Compliance with Trust Indenture Act.



Every amendment to or supplement of this Indenture or the Securities shall comply with the TIA as in effect at the date of such amendment or supplement.
In the event of any conflict between this Indenture and the TIA, the terms of the TIA shall govern.



Section 10.4 Revocation and Effect of Consents.



Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holders Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent

Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment,
supplement or waiver becomes effective.



After an amendment,
supplement or waiver becomes effective, it shall bind every Securityholder, unless it makes a change described in any of clauses (a) through (l) of Section 10.2. In that case the amendment, supplement or waiver shall bind each Holder of a Security
who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holders Security.



Section 10.5 Notation on or Exchange of Securities.



If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to
deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall
issue and the Trustee shall authenticate a new Security that reflects the changed terms.



Section 10.6 Trustee to Sign Amendments, Etc.



The Trustee shall sign any amendment or supplemental indenture authorized pursuant to this Article 10 if the amendment or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities
of the Trustee. If it does, the Trustee may, in its sole discretion, but need not sign it. In signing or refusing to sign such amendment or supplemental indenture, the Trustee shall be entitled to receive and, subject to Section 9.1, shall be fully
protected in relying upon, an Opinion of Counsel stating that such amendment or supplemental indenture is authorized or permitted by this Indenture. The Company may not sign an amendment or supplement indenture until the Board of Directors approves
it.



Section 10.7 Effect of Supplemental Indentures.



Upon the execution of any supplemental indenture under this Article, 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.

[FORM OF REVERSE SIDE OF SECURITY]

REWARDS NETWORK INC.

31⁄4% CONVERTIBLE SUBORDINATED DEBENTURES DUE 2023



| | 1. | INTEREST
| | -- | --------



Rewards Network Inc., a Delaware corporation formerly known as iDine Rewards Network Inc. (the Company, which term shall include any successor corporation under the Indenture hereinafter referred
to), promises to pay interest on the principal amount of this Security at the rate of 31⁄4% per annum. The Company shall pay interest semiannually on April 15 and October 15 of each year (each such date, an Interest Payment
Date), commencing April 15, 2004. Interest on the Securities shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from October 15, 2003; provided, however, that if there is not an
existing Default in the payment of interest and if this Security is authenticated between a record date referred to on the face hereof (each such date, a Interest Payment Record Date) and the next succeeding Interest Payment Date,
interest shall accrue from such Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. Any reference herein to interest accrued or payable as of any date shall include any Additional Interest accrued
or payable on such date as provided in the Registration Rights Agreement.



| | 2. | METHOD OF PAYMENT
| | -- | -----------------



The Company shall pay principal, interest and Additional Interest, if any, on this Security (except defaulted interest) to the person who is the Holder of
this Security at the close of business on April 1 or October 1, as the case may be, next preceding the related interest payment date. The Holder must surrender this Security to a Paying Agent to collect payment of principal. The Company will pay
principal and interest including Additional Interest, if any, in money of the United States that at the time of payment is legal tender for payment of public and private debts. The Company may, however, pay principal and interest and Additional
Interest, if any, in respect of any Certificated Security by check or wire payable in such money; provided, however, that a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately
available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Company at least ten business days prior to the payment date. The Company may mail an interest check to the Holders registered
address. Notwithstanding the foregoing, so long as this Security is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds to the account of the Depositary or its
nominee.



| | 3. | PAYING AGENT, REGISTRAR AND CONVERSION AGENT
| | -- | --------------------------------------------



Initially, LaSalle Bank National Association (the Trustee, which term shall include any successor trustee under the Indenture
hereinafter referred to) will act as Paying Agent, Registrar and Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without notice to the Holder. The Company or any of its Affiliates may, subject to certain
limitations set forth in the Indenture, act as Paying Agent or Registrar.



A-4



---

| | 4. | INDENTURE, LIMITATIONS
| | -- | ----------------------



This Security is one of a duly authorized issue of Securities of the Company designated as its 31⁄4% Convertible Subordinated Debentures Due 2023 (the
Securities), issued under an Indenture dated as of October 15, 2003 and as amended and restated as of February 4, 2004 (together with any supplemental indentures thereto, the Indenture), between the Company and
the Trustee. The terms of the Securities are qualified in their entirety by those stated in the Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of
the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture for a statement of such terms. The Securities are general subordinated unsecured obligations of the Company limited to $70,000,000 in
aggregate principal amount. The Indenture does not limit other debt of the Company, secured or unsecured, including Senior Indebtedness.



| | 5. | PURCHASE OF SECURITIES AT OPTION OF COMPANY
| | -- | -------------------------------------------



The Securities may be redeemed at the election of the Company, as a whole or from time to time in part, at any time on or after October 15, 2008, subject
to the terms and conditions of the Indenture, at a Redemption Price equal to 100% of the principal amount of the Security being redeemed, together with accrued and unpaid interest and Additional Interest, if any, up to, but not including, the
Redemption Date; provided, that if the Redemption Date falls after an Interest Payment Record Date and on or before an Interest Payment Date, then the interest and Additional Interest, if any, will be payable to the Holders in whose name the
Securities are registered at the close of business on the Interest Payment Record Date.



| | 6. | PURCHASE OF SECURITIES AT OPTION OF HOLDER UPON A CHANGE IN CONTROL
| | -- | -------------------------------------------------------------------



At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or any part
specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000 in excess thereof) of the Securities held by such Holder on the date that is 30 Business Days after the occurrence of a Change of
Control, at a purchase price equal to 100% of the principal amount thereof together with accrued and unpaid interest including Additional Interest, if any, up to, but excluding, the Change of Control Purchase Date, provided, that if a Change
of Control Purchase Date falls after an Interest Payment Record Date and on or before an Interest Payment Date, then the interest and Additional Interest, if any, will be payable to the Holders in whose name the Securities are registered at the
close of business on the Interest Payment Record Date. The Holder shall have the right to withdraw any Change of Control Purchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at any
time prior to 5:00 p.m., New York City time, on the second Business Day preceding the Change of Control Purchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture.



A-5



---

| | 7. | OPTIONAL PURCHASE AT OPTION OF HOLDER
| | -- | -------------------------------------



On October 15, 2008, October 15, 2013 and October 15, 2018 (each, an Optional Purchase Date), at the option of the Holder and subject
to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or any part specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000 in excess thereof) of the
Securities held by such Holder at a purchase price equal to 100% of the principal amount thereof together with accrued and unpaid interest including Additional Interest, if any, up to, but excluding, the Optional Purchase Date, provided, that
if an Optional Redemption Date falls after an Interest Payment Record Date and on or before an Interest Payment Date, then the interest and Additional Interest, if any, will be payable to the Holders in whose name the Securities are registered at
the close of business on the Interest Payment Record Date. The Holder shall have the right to withdraw any Optional Purchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at any time
prior to 5:00 p.m., New York City time, on the second Business Day preceding the Optional Purchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture.



| | 8. | CONVERSION
| | -- | ----------



A Holder of a Security may convert, at the option of the Holder, the principal amount of such Security (or any portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) into shares of
Common Stock at any time prior to the close of business on October 15, 2023; provided, however, if such Security is submitted or presented for purchase pursuant to Article 3 of the Indenture, such conversion right shall terminate upon the
delivery by the Holder of a Redemption Notice, Change of Control Purchase Notice or Optional Purchase Notice unless such notice has been validly withdrawn by such Holder in accordance with the Indenture for such Security or such earlier date as the
Holder presents such Security for purchase (unless the Company shall Default in making the Redemption Price, Change of Control Purchase Price or Optional Purchase Price payment when due, in which case the conversion right shall terminate at the
close of business on the date such Default is cured and such Security is purchased).



The initial Conversion Price is $17.89 per share, subject to adjustment under certain circumstances as provided in the Indenture. The number of shares of Common Stock issuable upon conversion of a Security is
determined by dividing the principal amount of the Security or portion thereof converted by the Conversion Price in effect on the Conversion Date. No fractional shares will be issued upon conversion; in lieu thereof, an amount will be paid in Cash
based upon the Closing Price (as defined in the Indenture) of Common Stock on the Trading Day immediately prior to the Conversion Date.



Upon conversion, the Company shall have the option, in its sole discretion, to satisfy its obligations to the Holder upon conversion by delivering to such
Holder (1) Common Stock, (2) Cash or (3) a combination of Common Stock and Cash as set forth in Section 4.15 of the Indenture.



A-6



---

To convert a Security, a Holder must (a) complete and manually sign the Conversion Notice set forth below
and deliver such notice to a Conversion Agent, (b) surrender the Security to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, and (d) pay any transfer or similar tax,
if required.



A Holder may convert a portion of a Security
equal to $1,000 or any integral multiple thereof.



A Holder of
a Security is not entitled to receive any accrued and unpaid interest and Additional Interest, if any, in respect of the Security upon, or from and after, the conversion of such Security.



A Holder of Securities is not entitled to any rights of a holder of Common Stock until such Holder has converted its
Securities to Common Stock, and only to the extent such Securities are deemed to have been converted into Common Stock pursuant to Article 4 of the Indenture.



A Security in respect of which a Holder had delivered a Change of Control Purchase Notice or an Optional Purchase Notice exercising the option of such
Holder to require the Company to purchase such Security may be converted only if the Change of Control Purchase Notice or Optional Purchase Notice is withdrawn in accordance with the terms of the Indenture.



| | 9. | SUBORDINATION
| | -- | -------------



The indebtedness evidenced by the Securities is, to the extent and in the manner provided in the Indenture, subordinate and junior in right of payment to
the prior payment in full in Cash or payment satisfactory to the holders of Senior Indebtedness of all Senior Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred and that the subordination is for the benefit of the
holders of the Senior Indebtedness. Any Holder by accepting this Security agrees to and shall be bound by such subordination provisions and authorizes the Trustee to give them effect. In addition to all other rights of Senior Indebtedness described
in the Indenture, the Senior Indebtedness shall continue to be Senior Indebtedness and entitled to the benefits of the subordination provisions irrespective of (a) any amendment, modification, or supplement of, or any waiver or consent to, any of
the terms of any Senior Indebtedness or the agreement or instrument governing any Senior Indebtedness, (b) the release or non-perfection of any collateral securing any Senior Indebtedness or (c) the manner of sale or other disposition of the
collateral securing any Senior Indebtedness or the application of the proceeds upon such sale.



| | 10. | DENOMINATIONS, TRANSFER, EXCHANGE
| | --- | ---------------------------------



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



A-7



---

| | 11. | PERSONS DEEMED OWNERS
| | --- | ---------------------



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



| | 12. | UNCLAIMED MONEY
| | --- | ---------------



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



| | 13. | AMENDMENT, SUPPLEMENT AND WAIVER
| | --- | --------------------------------



Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority of
the aggregate principal amount of the Securities then outstanding, and the Holders of at least a majority in aggregate principal amount of the Securities then outstanding may waive compliance in a particular instance by the Company with any
provision of this Indenture or the Securities without notice to any Holder. Without the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities to, among other things, cure any
ambiguity, omission, defect or inconsistency or make any other change that does not adversely affect the rights of any Holder.



| | 14. | SUCCESSOR ENTITY
| | --- | ----------------



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



| | 15. | DEFAULTS AND REMEDIES
| | --- | ---------------------



Under the Indenture, an Event of Default includes: (i) Default for 30 days in payment of any interest or Additional Interest on any Security; (ii) Default
in payment of any principal or premium, if any, on the Securities when due; (iii) failure by the Company for 60 days after notice to it to comply with any of its agreements or covenants contained in the Indenture or the Securities; (iv) Default in
the payment of the Redemption Price, Change of Control Purchase Price or Optional Purchase Price of any Security when due; (v) failure by the Company to issue Cash, Common Stock or any combination thereof upon conversion of Securities by a Holder in
accordance with the Indenture; (vi) failure by the Company to provide notice of a Change of Control when required by the Indenture; (vii) certain indebtedness is not discharged as set forth under the Indenture; and (viii) certain events of
bankruptcy, insolvency or reorganization of the Company or any Significant Subsidiary. If an Event of Default (other than as a result of certain events of bankruptcy, insolvency or reorganization of the Company) occurs and is continuing, the Trustee
or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may declare all unpaid principal on the Securities then outstanding to be due and payable immediately, all as and to the extent provided in the
Indenture. If an Event



A-8

CERTIFICATE TO BE DELIVERED UPON EXCHANGE OR REGISTRATION

OF TRANSFER OF RESTRICTED SECURITIES(5)



(5) This certificate should only be included if this Security is a Restricted Security.



Re: 3 1⁄4% Convertible Subordinated Securities Due 2008 (the Securities) of Rewards Network Inc.



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



 ̈book-entry or ̈definitive form by (the Transferor).



The Transferor has requested a Registrar or the Trustee to exchange or register the transfer of such Securities.



In connection with such request and in respect of each such Security, the
Transferor does hereby certify that the Transferor is familiar with transfer restrictions relating to the Securities as provided in Section 2.12 of the Indenture dated as of October 15, 2003 and as amended and restated as of February 4, 2004 between
Rewards Network Inc. and LaSalle Bank National Association, as trustee (the Indenture), and the transfer of such Security is being made pursuant to an effective registration statement under the Securities Act of 1933, as amended
(the Securities Act) (check applicable box) or the transfer or exchange, as the case may be, of such Security does not require registration under the Securities Act because (check applicable box):



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



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



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



A-16



---

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



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



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



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