(a) The Debentures shall be designated as the Floating Rate Convertible Senior Debentures due 2033 of the Company. The aggregate principal
amount of Debentures which may be authenticated and delivered under this Indenture is limited to $344,550,000, except for Debentures authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of other Debentures
pursuant to Sections 2.7, 2.8, 2.12, 7.5 or 10.7, hereof. The Debentures shall be issuable in denominations of $1,000 or integral multiples thereof.



(b) The Debentures shall mature on December 15, 2033 (the Stated Maturity).



(c) The Debentures shall bear Interest from the Issue Date until the
principal amount thereof is paid or made available for payment, or until such date on which the Debentures are converted, redeemed or purchased as provided herein at a per annum rate which will equal 3-month LIBOR, adjusted quarterly by the
Calculation Agent in accordance with the Security attached as Annex A hereto, minus a spread of 125 basis points, which spread may be reset upon the occurrence of a Reset Transaction, to, but not including, the effective date of any succeeding Reset
Transaction (as adjusted as provided herein and the Debentures, the Interest Rate). The Interest Rate for the initial interest period commencing on the Issue Date shall be 0.27% per annum. Notwithstanding anything to the contrary
contained herein or in the form of Security, the Interest Rate will never be less than zero. Interest shall be payable quarterly in arrears on each Interest Payment Date, commencing September 15, 2004, with interest payable in Dollars to Holders in
whose names the Debentures are registered at the close of business on the preceding Regular Record Date, except as otherwise provided herein and in the Debentures.



(d) In addition, interest (the Contingent Interest) will accrue on each Debenture during any quarterly
interest period commencing with the quarterly interest period beginning December 15, 2009, if the average Trading Price of a Debenture for the five Trading Days ending on the second Trading Day immediately preceding the beginning of the relevant
quarterly interest period equals 120% or more of the principal amount of such Debenture. The amount of Contingent Interest payable in respect of any quarterly period will equal 0.0625% of the average Trading Price of the Debentures over the
measuring period triggering the Contingent Interest payment. Upon determination that Holders of Debentures will be entitled to receive Contingent Interest during any relevant quarterly interest period, on or prior to the start of the relevant
quarterly interest period, the Company shall issue a press release and publish information with respect to any Contingent Interest on its web site. The Company shall pay Contingent Interest, if any, in the same manner as it shall pay Interest
pursuant to Section 2.1(c) hereof and the obligations of Holders in respect of the payment of Contingent Interest in connection with the conversion of any Debenture will also be the same as described in Section 2.1(f) hereof.



16



---

(e) Interest (including Contingent Interest) on the Debentures shall be computed on the basis of the
actual number of days for which Interest is payable in the relevant interest period, divided by 360. For purposes of determining the Interest Rate, the Trustee may assume that a Reset Transaction has not occurred unless the Trustee has received an
Officers Certificate of the Company stating that a Reset Transaction has occurred and specifying the Adjusted Spread then in effect.



(f) Interest (including Contingent Interest) shall be due and payable on a Debenture as follows:



(1) A registered Holder of any Debenture as of the close of
business on a Regular Record Date shall be entitled (except as otherwise indicated in this Section 2.1(f)) to receive and shall receive, as the registered Holder as of such Regular Record Date, Interest (including Contingent Interest) on such
Debenture on the corresponding Interest Payment Date (other than any Debenture whose Stated Maturity is prior to such Interest Payment Date).



(2) In the event that a Debenture becomes subject to redemption pursuant to Article 10 and the Redemption Date occurs after a Regular
Record Date, the Person whose Debenture becomes subject to redemption (and only such Person rather than the Holder as of such Regular Record Date) shall be entitled to receive and shall receive accrued and unpaid Interest (including Contingent
Interest) from the preceding Interest Payment Date (or such earlier date on which Interest, including Contingent Interest, if any, was last paid) to but not including the Redemption Date on such Debenture, even if such Person is not the Holder of
such Debenture.



(3) In the event that a
Debenture becomes subject to purchase pursuant to Article 11, a Holder of any Debenture who exercises a repurchase right with respect to such Debenture shall be entitled to receive and shall receive Interest (including Contingent Interest) to but
not including the applicable purchase date for such Debenture, which amount shall be included in the applicable purchase price thereof.



(4) In the event that a Debenture is converted pursuant to Article 12, the Holder who converts such Debenture on any date other than an
Interest Payment Date shall not be entitled to accrued and unpaid Interest (including Contingent Interest) from the preceding Interest Payment Date until the Conversion Date, or otherwise, on such Debenture, such amounts being deemed to have been
paid by receipt of shares of Common Stock in full rather than canceled, extinguished or forfeited; and, accordingly, a Holder which converts a Debenture after a Regular Record



17



---

Date but prior to the corresponding Interest Payment Date will receive accrued and unpaid Interest
(including Contingent Interest) for such period on such Interest Payment Date but will be required to remit to the Company an amount equal to that Interest (including Contingent Interest) at the time such Holder surrenders the Debenture for
conversion. The preceding sentence does not apply, however, to a Holder that converts, after a Regular Record Date for an interest payment date but prior to the corresponding Interest Payment Date, Debentures that the Company calls for redemption
prior to such conversion on a Redemption Date that is after such Regular Record Date and prior to such Interest Payment Date.



(g) Payment of any principal, Redemption Price, Repurchase Price and Interest and Contingent Interest, if any, on, Global Securities shall be payable by
the Company to the Depositary in immediately available funds.



(h) Payment of any principal on Physical Securities shall be made at the office or agency of the Company maintained for such purpose, initially the Corporate Trust Office of the Trustee. Interest, including Contingent Interest, if any, on
Physical Securities will be payable by (i) U.S. Dollar check drawn on a bank in The City of New York mailed to the address of the Person entitled thereto as such address shall appear in the Register, or (ii) upon written application to the Registrar
not later than the relevant Regular Record Date by a Holder of a principal amount of Securities in excess of $5,000,000, wire transfer in immediately available funds, which application shall remain in effect until the Holder notifies, in writing,
the Registrar to the contrary.



(i) The Debentures are
redeemable at the option of the Company as provided in and subject to Article 10.



(j) The Debentures shall be purchased by the Company at the option of Holders as provided in and subject to Article 11.

Guarantors as provided in Article 13 hereof.

effective pursuant to Section 13.3 of this Indenture shall bear a Restricted Securities Legend in substantially the following form:



THE SECURITY EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE



19



---

SECURITIES ACT), OR ANY STATE SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD WITHIN THE
UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. THE HOLDER HEREOF AGREES THAT UNTIL THE EXPIRATION OF TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THE COMMON STOCK EVIDENCED HEREBY,



(1) IT WILL NOT RESELL OR OTHERWISE TRANSFER
THE SECURITY EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT IS PURCHASING COMMON STOCK IN WITH A VALUE OF AT LEAST $100,000
AND THAT PRIOR TO SUCH TRANSFER, FURNISHES TO MELLON INVESTOR SERVICES LLC AS TRANSFER AGENT (OR ANY SUCCESSOR TRANSFER AGENT, AS APPLICABLE), A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND WARRANTIES RELATING TO THE RESTRICTIONS ON TRANSFER
OF THE COMMON STOCK EVIDENCED HEREBY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH TRUSTEE), (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (D) PURSUANT TO A REGISTRATION
STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER;



(2) PRIOR TO ANY SUCH TRANSFER OTHER THAN A TRANSFER PURSUANT TO CLAUSE (1)(D) ABOVE, IT WILL FURNISH TO MELLON INVESTOR SERVICES LLC (OR
ANY SUCCESSOR TRANSFER AGENT, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE COMPANY MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT
TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND



(3) IT WILL DELIVER TO EACH PERSON TO WHOM THE COMMON STOCK EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO A CLAUSE (1)(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.



20



---

THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY
PURSUANT TO CLAUSE (1)(D) ABOVE OR THE EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE SECURITY UPON THE CONVERSION OF WHICH THE COMMON STOCK EVIDENCED HEREBY WAS ISSUED.



(ii) Removal of the Restricted Securities Legends.



All shares of Common Stock issued upon conversion of any Debenture before
the date upon which the Fisher Guarantee becomes effective pursuant to Section 13.3 of this Indenture shall bear the Restricted Securities Legend, until the earlier of:



(1) the date which is two years after the original issuance date of such shares of Common Stock; and



(2) the date such shares of Common Stock have
been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such sale).



The Holder must give notice thereof to the Trustee, as applicable.



In the event Rule 144(k) as promulgated under the Securities Act is amended to shorten the two-year period under Rule
144(k), then the references in the restrictive legends set forth above and in the corresponding transfer restrictions described above to TWO YEARS and two years, respectively, will be deemed to refer to such shorter period,
from and after receipt by the Trustee of an Officers Certificate of the Company and an Opinion of Counsel of the Company to that effect. As soon as practicable after the Company knows of the effectiveness of any such amendment to shorten the
two-year period under Rule 144(k), unless such changes would otherwise be prohibited by, or would cause a violation of, the federal securities laws applicable at the time, the Company will provide to the Trustee an Officers Certificate of the
Company and an Opinion of Counsel of the Company as to the effectiveness of such amendment and the effectiveness of such change to the restrictive legends and transfer restrictions.



Notwithstanding the foregoing, the Restricted Securities Legend may be removed if there is delivered to the Company such
satisfactory evidence, which may include an opinion of independent counsel, as may be reasonably required by the Company that neither such legend nor the restrictions on transfer set forth therein are required to ensure that transfers of such shares
of Common Stock will not violate the registration requirements of the Securities Act. Upon provision of such satisfactory evidence, the Transfer Agent, at the written direction of the Company, shall authenticate and deliver in exchange for such
shares of Common Stock another certificate representing an equal number of shares of Common Stock that does not bear such legend. If the Restricted Securities Legend has been removed from such shares of Common Stock as provided above, no other
shares of Common Stock issued in exchange for all or any part of such shares of Common Stock shall bear such legend, unless the Company has



21



---

reasonable cause to believe that such other shares of Common Stock are restricted securities within the
meaning of Rule 144 and instructs the Transfer Agent in writing to cause a Restricted Securities Legend to appear thereon.



Any such shares of Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions
set forth in Section 2.3(a)(ii) for removal of the Restricted Securities Legend have been satisfied may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the Transfer
Agent, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the Restricted Securities Legend.



(b) Global Security Legend.



Each Global Security shall also bear the following legend on the face thereof:



UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS
AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT
HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE
REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS TO NOMINEES OF THE DEPOSITORY TRUST COMPANY OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSORS NOMINEE AND TRANSFERS OF
PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN ARTICLE 2 OF THE INDENTURE REFERRED TO ON THE REVERSE HEREOF.

THOUSAND DOLLARS ($250,000).



(d) Tax Legend.

INDENTURE.

and Dating of the Securities.



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



(b) At any time and from time to time after the
execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in

authentication substantially in the form provided for herein executed by or on behalf of the Trustee by manual signature,
and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. The Trustee may appoint an authenticating agent or agents reasonably acceptable to
the Company with respect to the Securities. Unless limited by the terms of such appointment, 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.

be dated the date of its authentication. The Trustee shall authenticate and deliver Securities for original issue upon one or more Company Orders without any further action by the Company. The aggregate principal amount of Securities Outstanding at
any time may not exceed $344,550,000 million.



Section 2.5
Registrar, Paying Agent and Calculation Agent.



The
Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the Registrar) and an office or agency where Securities may be presented for payment (the Paying
Agent). The Registrar shall keep a register of the Securities (the Register) and of their transfer and exchange. The Company may appoint one or more co Registrars and one or more additional Paying Agents for the
Securities. The term Paying Agent includes any additional paying agent and the term Registrar includes any additional registrar. The Company may change any Paying Agent or Registrar without prior notice to any Holder.



The Company shall also appoint a Calculation Agent to perform
the calculations required pursuant to this Indenture and the Securities.



The Company will cause each Paying Agent (other than The Bank of New York) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this
Section, that such Paying Agent will:



(1)
hold all sums of money or Common Stock held by it for the payment of any amounts due and payable in respect of the Securities in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise
disposed of as provided in this Indenture;



(2) give the Trustee notice of any Default by the Company in the making of any such payment; and



(3) at any time during the continuance of any such Default, upon the written request of the Trustee, forthwith pay to the Trustee all sums
so held in trust by such Paying Agent.



The Company shall give
prompt written notice to the Trustee of the name and address of any Agent who is not a party to this Indenture. If the Company fails to



24



---

appoint or maintain another entity as Registrar, Paying Agent, or Calculation Agent, the Trustee shall act as such. The
Company or any Affiliate of the Company may act as Paying Agent or Registrar; provided, however, that none of the Company, its subsidiaries or the Affiliates of the foregoing shall act:



(1) as Paying Agent in connection with redemptions, offers to purchase and discharges, except as otherwise
specified in this Indenture, and



(2) as
Paying Agent or Registrar if a Default or Event of Default has occurred and is continuing.



The Company hereby initially appoints The Bank of New York as Registrar, Paying Agent and Calculation Agent.



Section 2.6 Paying Agent to Hold Assets in Trust.



Not later than 10:00 a.m. (New York City time) on or prior to each due date of payments in respect of any Security, the Company shall deposit with one or
more Paying Agents a sum of money in immediately available funds sufficient to make such payments when so becoming due. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee,
the Paying Agent (if other than the Company) shall have no further liability for the money so paid over to the Trustee.



The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the making of payments in respect of the Securities and shall notify the Trustee of any Default by the Company in making any such payment. At any time during the continuance of any such
Default, the Paying Agent shall, upon the written request of the Trustee, forthwith pay to the Trustee all money so held in trust.



If the Company shall act as a Paying Agent, it shall, prior to or on each such due date, segregate and hold in trust for the benefit of the Holders a sum
sufficient with monies held by all other Paying Agents, to pay such amounts so becoming due until such sums shall be paid to such Persons or otherwise disposed of as provided in this Indenture, and shall promptly notify the Trustee of its action or
failure to act.



Section 2.7 General Provisions Relating to
Registration, Transfer and Exchange.



The Securities are
issuable only in registered form. A Holder may transfer a Security only by written application to the Registrar stating the name of the proposed transferee and otherwise complying with the terms of this Indenture. No such transfer shall be effected
until, and such transferee shall succeed to the rights of a Holder only upon, final acceptance and registration of the transfer by the Registrar in the Register. Furthermore, any Holder of a Global Security shall, by acceptance of such Global



25



---

Security, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry
system maintained by the Holder of such Global Security (or its agent) and that ownership of a beneficial interest in the Global Security shall be required to be reflected in a book-entry.



When Securities are presented to the Registrar with a request to register the
transfer or to exchange them for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if the requirements hereunder for such transactions are met
(including that such Securities are duly endorsed or accompanied by a written instrument of transfer duly executed by the Holder thereof or by an attorney who is authorized in writing to act on behalf of the Holder). Subject to Section 2.4, to
permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrars request. No service charge shall be made for any registration of transfer or exchange or redemption of
the Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or other similar governmental charge payable upon
issuances pursuant to Section 2.12 and exchanges pursuant to Sections 2.14, 7.5 or 10.7).



Neither the Company nor the Registrar shall be required to exchange or register a transfer of any Securities:



(1) for a period of 15 days prior to the day of mailing of notice of redemption of Securities under Article 10 hereof;



(2) so selected for redemption or, if a portion of any
Security is selected for redemption, such portion thereof selected for redemption; or



(3) surrendered for conversion or, if a portion of any Security is surrendered for conversion, such portion thereof surrendered for
conversion.



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 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 2.8 Book-Entry Provisions for the Global Securities.



(a) The Global Securities initially shall:



(1) be registered in the name of the Depositary; and



26



---

(2) be delivered to the Trustee as custodian for such Depositary, for credit to the
accounts of the members of, participants in, the Depositary (the Agent Members) holding the Securities evidenced thereby, registered with the Depositary for credit to the accounts of the Agent Members then holding such Securities
on behalf of Euroclear or Clearstream, as applicable).



Agent
Members shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under such Global Security, and the Depositary may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing contained herein shall prevent the Company, the Trustee or any agent of the Company
or Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and the Agent Members, the operation of customary practices governing the exercise of the
rights of a Holder of any Security. With respect to any Global Security deposited on behalf of the subscribers for the Securities represented thereby with the Trustee as custodian for the Depositary for credit to their respective accounts (or to
such other accounts as they may direct) at Euroclear or Clearstream, the provisions of the Operating Procedures of the Euroclear System and the Terms and Conditions Governing Use of Euroclear and the Management
Regulations and Instructions to Participants of Clearstream, respectively, shall be applicable to the Global Securities.



(b) The registered Holder of a Global Security 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.



(c) A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary, and no such transfer to any such other Person
may be registered. Beneficial interests in a Global Security may be transferred in accordance with the rules and procedures of the Depositary and the provisions of Section 2.9 hereof.



(d) If at any time:



(1) the Depositary notifies the Company in writing that it is no longer willing or able to continue to act as Depositary for the Global
Securities, or the Depositary ceases to be a clearing agency registered under the Exchange Act and a successor depositary for the Global Securities is not appointed by the Company within 90 days of such notice or cessation;



(2) the Company, at its option, notifies the Trustee in
writing that it elects to cause the issuance of the Physical Securities under this Indenture in exchange for all or any part of the Securities represented by a Global Security or Global Securities; or



27



---

(3) an Event of Default has occurred and is continuing and the Registrar has received a
request from the Depositary for the issuance of Physical Securities in exchange for such Global Security or Global Securities,



then the Depositary shall surrender such Global Security or Global Securities to the Trustee for cancellation and the Company shall execute, and the Trustee, upon receipt
of an Officers Certificate of the Company and Company Order for the authentication and delivery of Securities (which certificate and order the Company shall promptly deliver to the Trustee), shall authenticate and deliver in exchange for such
Global Security or Global Securities, Physical Securities in an aggregate principal amount equal to the aggregate principal amount of such Global Security or Global Securities. Such Physical Securities shall be registered in such names as the
Depositary shall identify in writing as the beneficial owners of the Securities represented by such Global Security or Global Securities (or any nominee thereof).



(e) In connection with any transfer of beneficial interests in a Global Security to the beneficial owners thereof pursuant
to Section 2.8(d) hereof, the Registrar shall reflect on its books and records the date and a decrease in the aggregate principal amount of such Global Security in an amount equal to the aggregate principal amount of the beneficial interest in such
Global Security to be transferred in the form of Physical Securities.



Section 2.9 [Reserved].



Section 2.10
Holder 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 Holders and shall otherwise comply with Section 312(a) of the TIA. If the Trustee is not the Registrar, the Company shall furnish to the Trustee
prior to or on each Interest Payment Date and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders relating to such Interest
Payment Date or request, as applicable.



Section 2.11
Persons Deemed Owners.



Prior to due presentment of a
Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of
principal of the Security or the payment of any Redemption Price or Repurchase Price in respect thereof and Interest (including Contingent Interest) thereon, if any, for any purpose under this Indenture, whether or not such Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.



28

Section 2.12 Mutilated, Destroyed, Lost or Stolen Securities.



If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and aggregate principal amount and bearing a number not contemporaneously outstanding.



If there is delivered to the Company and the Trustee



(1) evidence to their satisfaction of the destruction, loss
or theft of any Security, and



(2) such
security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of actual notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and, upon request, the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, and 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, the Company in its discretion, but subject to any conversion rights, may, instead of issuing a new Security, pay such Security, upon satisfaction of the condition set forth in the preceding
paragraph.



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



Every new Security issued pursuant to this Section 2.12 in
lieu of any destroyed, lost or stolen Security shall constitute an original contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and such new Security shall be
entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.



The provisions of this Section 2.12 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.



Section 2.13 Treasury Securities.



In
determining whether the Holders of the requisite principal amount of Outstanding Securities are present at a meeting of Holders for quorum purposes or have given any request, demand, authorization, direction, notice, consent or waiver hereunder,
Securities owned by the Company or any Affiliate of the Company shall be disregarded



29



---

and deemed not to be Outstanding, except that, in determining whether the Trustee shall be protected in relying upon any
such determination as to the presence of a quorum or upon any such request, demand, authorization, direction, notice, consent or waiver, only such Securities of which a Responsible Officer of the Trustee has received written notice and are so owned
shall be so disregarded.



Section 2.14 Temporary
Securities.



Pending the preparation of Securities in
definitive form, the Company may execute and the Trustee shall, upon written request of the Company, authenticate and deliver temporary Securities (printed or lithographed). Temporary Securities shall be issuable in any authorized denomination, and
substantially in the form of the Securities in definitive form but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every such temporary Security shall be
executed by the Company and authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the Securities in definitive form. Without unreasonable delay, the Company will execute and deliver
to the Trustee Securities in definitive form (other than in the case of Securities in global form) and thereupon any or all temporary Securities (other than any such Securities in global form) may be surrendered in exchange therefor, at each office
or agency maintained by the Company pursuant to Section 9.2 and the Trustee shall authenticate and deliver in exchange for such temporary Securities an equal principal amount of Securities in definitive form. Such exchange shall be made by the
Company at its own expense and without any charge therefor. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Securities in definitive form
authenticated and delivered hereunder.



Section 2.15
Cancellation.



All Securities surrendered for payment,
redemption, purchase, conversion, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities so delivered shall be canceled promptly by the Trustee, and no Securities
shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. Upon written instructions of the Company, the Trustee shall dispose of canceled Securities in accordance with its procedures for the
disposition of cancelled securities in effect as of the date of such disposition. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such
Securities unless the same are delivered to the Trustee for cancellation.



Section 2.16 CUSIP Numbers.



The Company in issuing the Securities may use CUSIP numbers (if then generally in use), and the Trustee shall use CUSIP numbers in notices of redemption or exchange as a convenience to Holders; provided that any such notice
shall state that no representation is made as to the correctness of such numbers either as printed on the



30



---

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



Section 2.17 Defaulted Interest.



If the Company fails to make a payment of principal, Redemption Price,
Repurchase Price or Interest (including Contingent Interest) on any Debenture when due and payable, it shall pay Interest (including Contingent Interest) on such amounts (to the extent lawful), which shall be calculated using the applicable Interest
Rate (such amounts, the Defaulted Interest). The Company may elect to pay such Defaulted Interest, plus any other Interest (including Contingent Interest) payable on it, to the Persons who are Holders on which the Interest (including
Contingent Interest) is due on a subsequent special record date. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Debenture. The Company shall fix any such special record date and
payment date for such payment. At least 15 days before any such special record date, the Company shall mail to Holders affected thereby a notice that states the special record date, the Interest Payment Date and amount to be paid.



ARTICLE 3



DISCHARGE OF INDENTURE



Section 3.1 Discharge of Liability on Securities.



When (i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.12) for cancellation or (ii)

the provisions of Section 12.12), Common Stock and/or cash sufficient to pay all amounts and deliver all Common Stock due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.12) on the date of their Stated
Maturity, the Redemption Date or the Conversion Date, as the case may be, and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 5.8, cease to be of further effect. The
Trustee shall join in the execution of a document prepared by the Company acknowledging satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers Certificate of the Company and Opinion of Counsel of the
Company and at the cost and expense of the Company.

further liability to the Holders with respect to such money or securities for that period commencing after the return thereof.

(h) except in accordance
with Section 13.3 hereof, any Guarantee shall be held in any judicial proceeding to be unenforceable or invalid.



33



---

A Default under clause (d) or (e) above is not an Event of Default until the Trustee notifies the
Company, or the Holders of at least 25% of the principal amount of the Debentures at the time outstanding notify the Company and the Trustee, of the Default and the Company does not cure such Default (and such Default is not waived) within the time
specified in clause (d) or (e) above after actual receipt of such notice. Any such notice must specify the Default, demand that it be remedied and state that such notice is a Notice of Default.



The Trustee shall, within 90 days of the occurrence of a Default, give to the
Holders of the Securities notice of all uncured Defaults known to it and written notice of any event which with the giving of notice or the lapse of time, or both, would become an Event of Default; provided, however, the Trustee shall be
protected in withholding such notice if it, in good faith, determines that the withholding of such notice is in the best interest of such Holders, except in the case of a Default in the payment of the Principal of or Interest (including Contingent
Interest) on, any of the Securities when due or in the payment of any redemption or Repurchase Right.



Section 4.2 Acceleration of Maturity; Rescission and Annulment.



If an Event of Default with respect to Outstanding Debentures (other than an Event of Default specified in Section 4.1(f) or
4.1(g) hereof) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Outstanding Debentures, by written notice to the Company, may declare due and payable 100% of the principal amount of all
Outstanding Debentures, plus any accrued and unpaid Interest (including Contingent Interest), to the date of payment. Upon a declaration of acceleration, such principal amount, and accrued and unpaid Interest (including Contingent Interest) to the
date of payment shall be immediately due and payable. If an Event of Default specified in Section 4.1(f) and 4.1(g) occurs, the principal, and accrued and unpaid Interest (including Contingent Interest) on the Outstanding Debentures shall become and
be immediately due and payable. Once the principal and accrued and unpaid Interest (including Contingent Interest) on the Outstanding Debentures shall become and be immediately due and payable, the Trustee may, at its discretion, proceed to protect
and enforce the rights of the Holders at appropriate judicial proceedings.



Section 4.3 Other Remedies.



If an Event of Default with respect to Outstanding Debentures occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the Defaulted Payment or Interest (including Contingent
Interest) due and payable on the Debentures or to enforce the performance of any provision of the Securities.



34



---

The Trustee may maintain a proceeding in which it may prosecute and enforce all rights of action and
claims under this Indenture or the Securities, even if it does not possess any of the Securities or does not produce any of them in the proceeding.



Section 4.4 Waiver of Past Defaults.



The Holders, either (a) through the written consent of not less than a majority of the principal amount of the Outstanding Debentures, or (b) by the
adoption of a resolution, at a meeting of Holders of the Outstanding Debentures at which a quorum is present, by the Holders of at least a majority of the principal amount of the Outstanding Debentures represented at such meeting, may, on behalf of
the Holders of all of the Debentures, waive an existing Default or Event of Default, except a Default or Event of Default:



(1) set forth in Sections 4.1(a), (b) and (c), provided, however, that subject to Section 4.7, the Holders of a majority of the
principal amount of the Outstanding Debentures may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration; or



(2) in respect of a covenant or provision hereof which, under Section 7.2 hereof, cannot be modified or
amended without the consent of the Holders of each Outstanding Debentures affected;



provided that any such waiver or rescission would not conflict with any judgment or decree of a court of competent jurisdiction.



Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this
Indenture; provided, however, that in the event such declaration of acceleration has been made based on the existence of an Event of Default under Section 4.1(e) and the default with respect to Indebtedness for money borrowed which gave rise to such
Event of Default has been remedied, cured or waived, then, without any further action by the Holders, such declaration of acceleration shall be rescinded automatically and the consequences of such declaration shall be annulled. No such rescission or
annulment shall affect any subsequent Default or impair any right consequent thereon; and provided, further, that no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.



35



---

Section 4.5 Control by Majority.



The Holders of a majority of the principal amount of the Outstanding Debentures (or such lesser amount as shall have acted
at a meeting pursuant to the provisions of this Indenture) shall have the right to 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 the Trustee.
However, the Trustee may refuse to follow any direction that:



(1) conflicts with any law or with this Indenture;



(2) the Trustee determines may be unduly prejudicial to the rights of the Holders not joining therein; or



(3) may expose the Trustee to personal liability.



The Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction.



Section 4.6
Limitation on Suit.



No Holder of any Security shall have
any right to pursue any remedy with respect to this Indenture or the Securities (including, instituting any proceeding, judicial or otherwise, with respect to this Indenture or for the appointment of a receiver or trustee) unless:



(1) such Holder has previously given written notice to the
Trustee of an Event of Default that is continuing;



(2) the Holders of at least 25% of the principal amount of the Outstanding Debentures shall have made written request to the Trustee to pursue the remedy;



(3) such Holder or Holders have offered to the Trustee indemnity satisfactory to it against any costs,
expenses and liabilities incurred in complying with such request;



(4) the Trustee has failed to comply with the request for 60 days after its receipt of such notice, request and offer of indemnity; and



(5) during such 60-day period, no direction inconsistent with such written request has been given to the
Trustee by the Holders of a majority of the principal amount of the Outstanding Debentures (or such amount as shall have acted at a meeting pursuant to the provisions of this Indenture);



36



---

provided, however, that no one or more of such Holders may use this Indenture to prejudice the rights of another
Holder or to obtain preference or priority over another Holder.



Section 4.7 Unconditional Rights of Holders to Receive Payment and to Convert.



Notwithstanding any other provision in this Indenture, the Holder of any Debenture shall have the right, which is absolute and unconditional, to receive
payment of the principal amount, Redemption Price or Repurchase Price, and Interest (including Contingent Interest) in respect of the Debentures held by such Holder, on or after the respective due dates expressed in the Debenture or any Redemption
Date or Repurchase Date, and to convert the Debenture in accordance with Article 12, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, and such rights shall not be impaired or
affected adversely without the consent of such Holder.



Section 4.8 Collection of Indebtedness and Suits for Enforcement by the Trustee.



The Company covenants that if:



(1) a Default or Event of Default is made in the payment of Interest (including Contingent Interest) on any Debenture when such Interest
(including Contingent Interest) becomes due and payable and such Default or Event of Default continues for a period of 30 days; or



(2) a Default or Event of Default is made in the payment of the principal amount, Redemption Price or Repurchase Price on any Debenture
when the same becomes due and payable at its Stated Maturity, upon redemption, upon declaration when due for purchase by the Company or otherwise,



then the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Debenture, the entire principal then due and payable (as expressed
therein or as a result of any acceleration effected pursuant to Section 4.2 hereof) on such Debenture for any such amounts and, to the extent legally enforceable, Interest (including Contingent Interest) on such Debenture, and, in addition thereto,
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.



If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company
and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company, wherever situated.

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.



Section 4.9 Trustee May File Proofs of Claim.



In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or the property of the Company or its creditors, the Trustee (irrespective of whether the principal amount, Redemption Price, Repurchase Price or Interest (including Contingent Interest) in respect of the
Debentures shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any such amount) shall be entitled and empowered, by
intervention in such proceeding or otherwise:



(1) to file and prove a claim for the whole amount of the principal amount, Redemption Price, Repurchase Price or Interest (including Contingent Interest) owing and unpaid in respect of the Debentures and to file such other papers or
documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders of Debentures
allowed in such judicial proceeding and



(2)
to collect and receive any monies, Common Stock or other property payable or deliverable on any such claim and to distribute the same,



and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceedings is hereby authorized by each Holder of
Debentures 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 of Debentures, 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 5.8.



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

Section 4.10 Restoration of Rights and Remedies.



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



Section 4.11 Rights
and Remedies Cumulative.



Except as otherwise provided
with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 2.12, no right or remedy conferred in this Indenture upon or reserved to the Trustee or to the Holders of Securities is
intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.



Section 4.12 Delay or Omission Not Waiver.



No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event
of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders of Securities may be exercised
from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Securities, as applicable.

Section 5.8;



SECOND: to Holders for amounts
due and unpaid on the Securities for the principal amount, Redemption Price, Repurchase Price or Interest (including Contingent Interest) as applicable, ratably, without preference or priority of any kind, according to such amounts due and payable
on the Debentures; and



39



---

THIRD: any remaining amounts shall be repaid to the Company.



The Trustee may fix a special record date and payment date for any payment to
Holders pursuant to this Section 4.13. At least 15 days before such special record date, the Trustee shall mail to each Holder and the Company a notice that states the special record date, the payment date and the amount to be paid.



Section 4.14 Undertaking for Costs.



All parties to this Indenture agree, and each Holder of any Debenture by
such Holders acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, 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,
suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys fees,
against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more than 10% of the principal amount of the Outstanding Debentures, or to any suit instituted by any Holder of any Debenture for the enforcement of (i) payments pursuant to
Section 4.7, (ii) repurchase rights in accordance with Article 11 or (iii) conversion rights in accordance with Article 12. This Section 4.14 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from
this Indenture, as permitted by the TIA.



Section 4.15
Waiver of Stay or Extension Laws.



The Company covenants
(to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim to take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force,
which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

(7) The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty unless so specified herein.



Section 5.3 Individual Rights of Trustee



The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any Affiliate
of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as such term is defined in Section 310(b) of the TIA), it must eliminate such conflict within 90
days, apply to the Commission for permission to continue as trustee (to the extent permitted under Section 310(b) of the TIA) or resign. Any agent may do the same with like rights and duties. The Trustee is also subject to Sections 5.11 and 5.12
hereof.



Section 5.4 Money Held in Trust



Money held by the Trustee in trust hereunder shall not be segregated from
other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise expressly agreed in writing with the Company.



Section 5.5 Trustees Disclaimer.



The recitals contained herein and in the Securities (except for those in the certificate of
authentication) shall be taken as the statements of the Company, and the



43



---

Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity,
sufficiency or priority of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Company of Securities or the proceeds thereof.



Section 5.6 Notice of Defaults.



Within 90 days after the occurrence of any Default or Event of Default hereunder of which the Trustee has received written
notice, the Trustee shall give notice to Holders, unless such Default or Event of Default shall have been cured or waived; provided, however, that, except in the case of a Default or Event of Default described in Sections 4.1(a) or (b), the Trustee
shall be protected in withholding such notice if and so long as Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders. The proviso in the first sentence of this Section 5.6
shall be in lieu of the proviso to Section 315(b) of the TIA and such proviso is hereby expressly excluded from this Indenture, as permitted by the TIA. The Trustee shall not be deemed to have knowledge of a Default unless a Responsible Officer of
the Trustee has received written notice of such Default.



Section 5.7 Reports by Trustee to Holders.



The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required by Section 313 of the TIA at the times and in the manner provided by the TIA. If required by Section 313(a) of
the TIA, the Trustee shall, within 60 days after each September 15 following the date of this Indenture deliver to Holders a brief report, dated as of such September 15, which complies with the provisions of such Section 313(a).



A copy of each report at the time of its mailing to Holders shall be filed
with the Commission, if required, and each stock exchange, if any, on which the Securities or the Common Stock are listed. The Company or Fisher, as applicable, shall promptly notify the Trustee when the Securities or the Common Stock become listed
on any stock exchange and of any delisting thereof.



Section
5.8 Compensation and Indemnification.



The Company
covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation as agreed to in writing by the Trustee and the Company (which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) and the Company covenants and agrees to pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in accordance with
any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ), except to the extent that any such expense,
disbursement or advance is due to its negligence or bad faith. When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 4.1, the



44



---

expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are
intended to constitute expenses of administration under any bankruptcy law. The Company also covenants to indemnify the Trustee and its officers, directors, employees and agents for, and to hold such Persons harmless against, any loss, liability or
expense incurred by them, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder or the performance of their duties hereunder, including the costs and expenses of defending themselves against
or investigating any claim (whether asserted by the Company, a Guarantor, a Holder or any other Person) of liability in the premises, except to the extent that any such loss, liability or expense was due to the negligence or willful misconduct of
such Persons. The obligations of the Company under this Section 5.8 to compensate and indemnify the Trustee and its officers, directors, employees and agents and to pay or reimburse such Persons for expenses, disbursements and advances shall
constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee. Such additional indebtedness shall be a lien prior to that of the Securities upon
all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities, and the Securities are hereby subordinated to such senior claim. Trustee for purposes of
this Section 5.8 shall include any predecessor Trustee, but the negligence or willful misconduct of any Trustee shall not affect the indemnification of any other Trustee.



Section 5.9 Replacement of Trustee.



A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the
successor Trustees acceptance of appointment as provided in this Section 5.9.



The Trustee may resign and be discharged from the trust hereby created by so notifying the Company in writing. The Holders of at least a majority of the principal amount of Outstanding Debentures may remove the
Trustee by so notifying the Trustee and the Company in writing. The Company must remove the Trustee if:



(i) the Trustee fails to comply with Section 5.11 hereof or Section 310 of the TIA;



(ii) the Trustee becomes incapable of acting;



(iii) the Trustee is adjudged a bankrupt or an insolvent or
an order for relief is entered with respect to the Trustee under any Bankruptcy Law; or



(iv) a Custodian or public officer takes charge of the Trustee or its property.



If the Trustee resigns or is removed or if a vacancy exists in the office of
the Trustee for any reason, the Company shall promptly appoint a successor Trustee. The Trustee shall be entitled to payment of its fees and reimbursement of its expenses while



45



---

acting as Trustee. Within one year after the successor Trustee takes office, the Holders of at least a majority of the
principal amount of Outstanding Debentures may appoint a successor Trustee to replace the successor Trustee appointed by the Company.



Any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee if the Trustee fails
to comply with Section 5.11.



If an instrument of acceptance by
a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation or removal, the resigning or removed Trustee, as applicable, may petition, at the expense of the Company, any court of
competent jurisdiction for 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. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have
all the rights, powers and duties of the Trustee under this Indenture. The Company shall issue a notice of the successor Trustees succession to the Holders. Upon payment of its charges, the retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, subject nevertheless to its lien, if any, provided for in Section 5.8 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 5.9 hereof, the Companys obligations under
Section 5.8 hereof shall continue for the benefit of the retiring Trustee with respect to expenses, losses and liabilities incurred by it prior to such replacement.



Section 5.10 Successor Trustee by Merger, Etc.



Subject to Section 5.11 hereof, if the Trustee consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust business to, another corporation or national banking association, the successor entity without any further act shall be the successor Trustee as to the Securities.



Section 5.11 Corporate Trustee Required; Eligibility.



The Trustee shall at all times satisfy the requirements of
Section 310(a)(1), (2) and (5) of the TIA. The Trustee shall at all times have (or, in the case of a corporation included in a bank holding company system, the related bank holding company shall at all times have), a combined capital and surplus of
at least $50 million as set forth in its (or its related bank holding companys) most recent published annual report of condition. The Trustee is subject to Section 310(b) of the TIA.



Section 5.12 Collection of Claims Against the Company.



The Trustee is subject to Section 311(a) of the TIA, excluding any creditor
relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated therein.

all the Debentures and the performance of every covenant of this Indenture and the Debentures on the part of the Company to be performed or observed and shall have provided for conversion rights provided in Article 12;

Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and



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

Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor corporation had
been named as the Company herein. In the event of any such conveyance or transfer, the Company (which term shall for this purpose mean the Person named as the Company in the first paragraph of this Indenture or any successor Person which
shall theretofore become such in the manner described in Section 6.1 hereof), except in the case of a lease to another Person, shall be relieved of all obligations and covenants under this Indenture and the Securities and may be dissolved and
liquidated.

ARTICLE 10



REDEMPTION OF DEBENTURES



Section 10.1 Optional Redemption.



(a) At any time on or after March 15, 2010, except for Debentures that it is
required to purchase pursuant to Section 11.1 or required to convert pursuant to Section 12.1, the Company may, at its option, redeem the Debentures in whole at any time or in part from time to time, on any date prior to the Stated Maturity of such
Debentures, upon notice as set forth in Section 10.4, at the Redemption Price.



(b) If the Company exercises its option to redeem the Debentures pursuant to this Section 10.1, a Holder may nevertheless exercise its right to have its Debentures purchased pursuant to Section 11.1, if applicable, or
to convert such Debentures pursuant to Article 12, in each case, until the close of business two Business Days immediately preceding the Redemption Date.



(c) The Company shall pay to the Holder of the Debentures called for redemption (including those Debentures which are converted into Common Stock after
the date the notice of the redemption is mailed and prior to the Redemption Date) any Interest (including Contingent Interest) accrued but not paid to, but excluding, the



57



---

Redemption Date pursuant to Section 2.1(f); provided, however, that if the Redemption Date is an Interest Payment Date,
the Company shall pay the Interest (including Contingent Interest) to the Holder of the Debentures on the relevant Regular Record Date.



Section 10.2 Notice to Trustee.



If the Company elects to redeem Debentures pursuant to the provisions of Section 10.1 hereof (such election to be ordered by a Board Resolution), it shall
notify the Trustee at least 60 days prior to the intended Redemption Date (unless a shorter notice shall be satisfactory to the Trustee) of (i) such intended Redemption Date, (ii) the principal amount of Debentures to be redeemed and (iii) the CUSIP
numbers of the Debentures to be redeemed.



Section 10.3
Selection of Debentures to Be Redeemed.



If fewer than all
the Debentures are to be redeemed, the Trustee shall select the particular Debentures to be redeemed from the Outstanding Debentures by a method that complies with the requirements of any exchange on which the Debentures are listed, or, if the
Debentures are not listed on an exchange, on a pro rata basis or by lot or in accordance with any other method the Trustee considers fair and appropriate. The Trustee may select for redemption portions of the principal amount of Debentures that have
denominations larger than $1,000.



Debentures and portions
thereof that the Trustee selects shall be in principal amounts in integral multiples of $1,000. Provisions of this Indenture that apply to Debentures called for redemption also apply to portions of Debentures called for redemption. The Trustee shall
notify the Company promptly of the Debentures or portions of Debentures to be redeemed.



The Trustee shall promptly notify the Company and the Registrar in writing of the Debentures selected for redemption and, in the case of any Debentures selected for partial redemption, the principal amount thereof to
be redeemed.



If any Debenture selected for partial redemption
is converted or elected to be purchased in part before termination of the conversion right or repurchase right with respect to the portion of the Debenture so selected, the converted or purchased portion of such Debenture shall be deemed to be the
portion selected for redemption; provided, however, that the Holder of such Debenture so converted or purchased and deemed redeemed shall not be entitled to any additional interest payment as a result of such deemed redemption than such Holder would
have otherwise been entitled to receive upon conversion or purchase of such Debenture subject to Section 2.1(f). Debentures which have been converted or purchased during a selection of Debentures to be redeemed may be treated by the Trustee as
Outstanding for the purpose of such selection.



For all
purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Debentures shall relate, in the case of any Debenture redeemed or to be redeemed only in part, to the portion of the principal amount of
such Debenture which has been or is to be redeemed.

The notice given shall specify the last date on which
exchanges or transfers of Debentures may be made pursuant to Section 2.7, and shall specify the serial numbers of Debentures and the portions thereof called for redemption.

Notice of redemption of Debentures to be redeemed at the election of the Company shall be given by the
Company or, at the Companys written request delivered at least 20 days prior to the date of the mailing of such Notice (unless a shorter period shall be acceptable to the Trustee), by the Trustee in the name of and at the expense of the
Company.



Section 10.5 Effect of Notice of Redemption.



Notice of redemption having been given as provided in Section
10.4 hereof, the Debentures so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued and unpaid
Interest (including Contingent Interest)) such Debentures shall cease to bear Interest (including Contingent Interest). Upon surrender of any such Debenture for redemption in accordance with such notice, such Debenture shall be paid by the Company
at the Redemption Price; provided, however, the installments of Interest (including Contingent Interest) on Debentures whose Stated Maturity is prior to or on the Redemption Date shall be payable to the Holders of such Debentures, or one or
more Predecessor Securities, registered as such on the relevant Regular Record Date.



If any Debenture called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid, bear Interest (including Contingent Interest) from the Redemption Date at the
Interest Rate.



Section 10.6 Deposit and Payment of
Redemption Price.



Prior to or by 10:00 a.m. (New York
City time) on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided
in Section 2.6) an amount of money in immediately available funds sufficient to pay the Redemption Price, and accrued and unpaid Interest (including Contingent Interest) in respect of all the Debentures to be redeemed on that Redemption Date from
the last Interest Payment Date to but not including the Redemption Date, other than any Debentures called for redemption on that date which have been converted prior to the date of such deposit, and accrued and unpaid Interest (including Contingent
Interest) on such Debentures. The Trustee and Paying Agent shall then cause such funds to be paid to the Holders of the Debentures being redeemed in accordance with this Article.



If any Debenture delivered for redemption shall not be so redeemed by payment to the Holders thereof on the Redemption Date,
the principal amount of such Debenture shall, until it is redeemed, bear Interest (including Contingent Interest) on the Redemption Date to but not including the actual date of redemption at the applicable Interest Rate, and each such Debenture
shall remain convertible into shares of Common Stock pursuant to Article 12 until such Debenture shall have been so redeemed.



60

If any Debenture called for redemption is converted, any money deposited with the Trustee or with a Paying Agent or so
segregated and held in trust for the redemption of such Debenture shall (subject to any right of the Holder of such Debenture or any Predecessor Security to receive Interest (including Contingent Interest) as provided in Section 2.1(f)) be paid to
the Company upon request by the Company or, if then held by the Company, shall be discharged from such trust.



Section 10.7 Debentures Redeemed in Part.



Any Debenture which is to be redeemed only in part shall be surrendered at an office or agency of the Company designated for that purpose pursuant to
Section 9.2 hereof (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or the Holders attorney duly
authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Debenture without service charge, a new Debenture of any authorized denomination as requested by such Holder in principal
amount equal to and in exchange for the unredeemed portion of the Debenture so surrendered.

Section 11.5 Deposit and Payment of the Applicable Repurchase Price.



(a) If a Holder has exercised its rights pursuant to Section 11.1(a) or
11.1(b) and has satisfied the conditions for the exercise of such rights in accordance with Section 11.4(a) or 11.4(b), as the case may be, then the Company shall, prior to 10:00 a.m. (New York City time) on the applicable Repurchase Date deposit
with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.5) an amount of money in immediately available
funds if deposited on such Business Day sufficient to pay the aggregate Repurchase Price of all the Debentures or portions thereof which are to be purchased on such applicable Repurchase Date, and the Trustee or Paying Agent, as applicable, shall
pay the Holder the Repurchase Price multiplied by the principal amount of Debentures for which such rights were exercised on the applicable Repurchase Date.



(b) There shall be no purchase of any Debenture pursuant to Section 11.1(a) or 11.1(b) if there has occurred (prior to, on or after, as applicable, the
giving, by the Holders of such Debenture, of the required Repurchase Notice) and is continuing an Event of Default (other than a default in the payment of the Repurchase Price with respect to such Debenture). The Paying Agent will promptly return to
the respective Holders thereof any Debenture (x) with respect to which a Repurchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of
the Repurchase Price with respect to such Securities) in which case, upon such return, the Repurchase Notice with respect thereto shall be deemed to have been withdrawn.



(c) If any Debenture delivered for purchase pursuant to Section 11.1(a) or 11.1(b) shall not be so paid on the Repurchase
Date, the principal amount of such Debenture shall, until it is paid, bear Interest (including Contingent Interest) from the purchase date to but not including the date of actual payment hereunder at the applicable Interest Rate, and each such
Debenture shall remain convertible pursuant to Article 12 until such Debenture shall have been paid.



Section 11.6 Effect of Delivery of Repurchase Notice and Purchase.



(a) Upon receipt by the Paying Agent of a Repurchase Notice, the Holder of the Debenture in respect of which such Repurchase
Notice was delivered shall (unless such Repurchase Notice is withdrawn pursuant to Section 11.3(c)) thereafter be entitled to receive solely the Repurchase Price with respect to such Debenture, and, if applicable, any accrued and unpaid Interest
(including Contingent Interest) pursuant to Section 2.1(f). Debentures in respect of which a Repurchase Notice has been delivered by the Holder thereof may not be converted pursuant to Article 12 on or after the date of the delivery of such
Repurchase Notice unless such Repurchase Notice which has been completed and delivered to the Paying Agent has first been validly withdrawn pursuant to Section 11.3(c).



66



---

(b) All Debentures delivered for purchase shall be canceled by the Trustee or Paying Agent, as
applicable.



Section 11.7 Physical Securities Purchased in
Part.



Any Physical Security which is to be purchased only
in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or such Holders attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Debentures, without service charge, new Debentures, of any authorized denomination
as requested by such Holder in principal amount equal to, and in exchange for, the portion of the principal amount of the Debentures so surrendered which is not purchased.



Section 11.8 Covenant to Comply With Securities Laws Upon Repurchase of Securities.



When complying with the provisions of this Article 11 (if such offer or
purchase constitutes an issuer tender offer for purposes of Rule 13e 4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), the Company shall (a) comply
with Rule 13e 4 and Rule 14e 1 under the Exchange Act, (b) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act and (c) otherwise comply with all federal and state securities laws so as to permit the rights
and obligations under this Article 11 to be exercised in the time and in the manner specified in this Article 11.



Section 11.9 Repayment to the Company.



The Trustee and the Paying Agent shall return to the Company upon written request any cash that remains unclaimed, together with interest or dividends, if
any, thereon (subject to the provisions of Section 5.4), held by them for the payment of the Repurchase Price; provided, however, that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 11.5 exceeds the
aggregate Repurchase Price of the Debentures or portions thereof which the Company is obligated to purchase on the purchase date then, unless otherwise agreed in writing with the Company, promptly after the Business Day following such purchase date,
the Trustee or Paying Agent, as applicable, shall return any such excess to the Company together with interest or dividends, if any, thereon, subject to the provisions of Section 5.4.



ARTICLE 12



CONVERSION OF SECURITIES



Section 12.1 Conversion Privilege.



(a) Subject to and upon compliance with the provisions of this Article, at the option of the Holder, any Debenture or any portion of the principal amount
thereof



67



---

which is an integral multiple of $1,000 may be converted at the principal amount thereof, or of such portion thereof,
into duly authorized, fully paid and nonassessable shares of Common Stock (subject to Section 12.12 hereof), at the Conversion Price, determined as hereinafter provided, in effect at the time of conversion:



(1) during any fiscal quarter, if the Sale Price of the
Common Stock for at least 20 Trading Days in the 30 consecutive Trading-Day period ending on the last day of the preceding fiscal quarter was more than 130% of the Conversion Price on that thirtieth Trading Day;



(2) on or before December 15, 2028, during the five Business
Day period following any five consecutive Trading-Day period in which the average of the Trading Prices for the Debentures, as determined following a written request by a Holder of Debentures delivered to the Company in accordance with Section 14.2,
to make a determination, for that five Trading-Day period was less than 97% of the average Conversion Value for the Debentures during such period; provided, however, if on the Conversion Date, the Sale Price of the Common Stock is greater than the
then current Conversion Price and less than or equal to 130% of the then current Conversion Price, and the Debentures are not otherwise convertible, the Company may satisfy such conversion, at its option, in cash, Common Stock or a combination of
cash and Common Stock with a value equal to the principal amount of such Debenture to be converted (any such Common Stock so utilized to satisfy such conversion pursuant to this proviso will be valued at 100% of the average of the Sale Prices of the
Common Stock for the five Trading Days ending on the third Trading Day immediately preceding the Conversion Date);



(3) during any period, following the date the Debentures are rated by both Moodys and by Standard and Poors, (1) when the
credit ratings assigned to the Debentures by Moodys is lower than B3 or by Standard & Poors is lower than B-, (2) in which the credit rating assigned to the Debentures is suspended or withdrawn by either
rating agency, or (3) in which neither agency continues to rate the Debentures or provide ratings services or coverage to the Company;



(4) if the Company has called the Debentures for redemption; or



(5) upon the occurrence of any of the corporate transactions specified in clause (b) of this Section 12.1.



The Company shall determine on a daily basis whether the
Debentures shall be convertible as a result of the occurrence of an event specified in clause (1) or, following a request by a Holder of Debentures delivered to the Company, clause (2) above and, if the Debentures shall be so convertible, the
Company shall promptly deliver to the Trustee written notice thereof. Whenever the Debentures shall become convertible



68



---

pursuant to Section 12.1, the Company or, at the Companys written request, the Trustee in the name and at the
expense of the Company, shall notify the Holders of the event triggering such convertibility in the manner provided in Section 14.2, and the Company shall also publicly announce such information and publish it on the Companys web site. Any
notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice.



Notwithstanding anything to the contrary contained herein, the Conversion Agent shall have no obligation to determine the Trading Price of the Debentures
pursuant to clause (2) above, unless the Company shall have requested that it make such determination; and the Company shall have no obligation to make such request unless so requested by a Holder. At such time as a written request is made by a
Holder, the Company shall instruct the Conversion Agent to determine the Trading Price of the Debentures beginning on the next Trading Day and on each successive Trading Day until the Trading Price of the Debentures is greater than or equal to 97%
of the average Conversion Value for five consecutive Trading Days.



69



---

(b) In addition, in the event that:



(1) (A) Fisher distributes to all or substantially all holders of its shares of Common Stock rights or
warrants entitling them (for a period expiring within 60 days of the Record Date for such distribution) to subscribe for or purchase shares of Common Stock, at a price per share less than the Sale Price of the Common Stock on the Business Day
immediately preceding the announcement of such distribution, (B) Fisher distributes to all or substantially all holders of its shares of Common Stock, cash or other assets, debt securities or rights or warrants to purchase its securities, where the
Fair Market Value (as determined by the Board of Directors) of such distribution per share of Common Stock exceeds 5% of the Sale Price of a share of Common Stock on the Business Day immediately preceding the date of declaration of such
distribution, or (C) a Change of Control occurs but Holders of Debentures do not have the right to require the Company to purchase their Debentures as a result of such Change of Control because either (i) the Sale Price of the Common Stock for
specified periods (as described in the definition of Change of Control) exceeds specified levels (as described in the definition of Change of Control) or (ii) the consideration received in such Change of Control consists of Capital Stock that is
freely tradeable and the Debentures become convertible into that Capital Stock as specified in the definition of Change of Control, then, in each case, the Debentures may be surrendered for conversion at any time on and after the date that the
Company gives notice to the Holders of such right, which shall be not less than 20 days prior to the Ex-Dividend Time for such distribution, in the case of (A) or (B), or within 30 days after the occurrence of the Change of Control, in the case of
(C), until the earlier of the close of business on the Business Day immediately preceding the Ex-Dividend Time or the date the Company announces that such distribution will not take place, in the case of (A) or (B), or the earlier of 30 days after
the Companys delivery of the Repurchase Notice for Change of Control Repurchase Rights or the date the Company announces that the Change of Control will not take place, in the case of (C), or



(2) Fisher consolidates with or merges into another
corporation, or is a party to a binding share exchange pursuant to which the shares of Common Stock would be converted into cash, securities or other property as set forth in Section 12.4 hereof, then the Debentures may be surrendered for conversion
at any time from and after the date which is 15 days prior to the date announced by Fisher as the anticipated effective time of such transaction until 15 days after the actual date of such transaction.



The Conversion Rate, at any time, shall equal (A) $1,000 divided by the
Conversion Price at such time, rounded to four decimal places (rounded up if the fifth decimal place thereof is 5 or more and otherwise rounded down).

Section 12.2 Conversion Procedure; Conversion Price; Fractional Shares.



(a) Upon conversion, the Company has the option, as set forth in Section
12.12, to deliver cash or a combination of cash and Common Stock, in lieu of Common Stock in order to satisfy its Conversion Obligation; provided, however, that the Company has the unilateral right, exercisable at any time, to deliver an
Officers Certificate of the Company to the Trustee and notice to the Holders, each stating that it shall be thereafter obligated to satisfy certain of its Conversion Obligation in cash. If the Company chooses to settle the Conversion
Obligation in Common Stock, Debentures shall be convertible at the office of the Conversion Agent into fully paid and nonassessable shares (calculated to the nearest 1/100th of a share) of Common Stock and will be converted into shares of Common
Stock at the Conversion Price therefor. No payment or adjustment shall be made in respect of dividends on the Common Stock or accrued interest on a converted Debenture, except as described in Section 12.9 hereof. Fisher shall not issue any fraction
of a share of Common Stock in connection with any conversion of Debentures, but instead the Company shall, subject to Section 12.3(h) hereof, make a cash payment (calculated to the nearest cent) equal to such fraction multiplied by the Sale Price of
the Common Stock on the last Trading Day prior to the date of conversion. Notwithstanding the foregoing, a Debenture in respect of which a Holder has delivered a Repurchase Notice exercising such Holders option to require the Company to
repurchase such Debenture may be converted only if such notice of exercise is withdrawn in accordance with Section 11.3 hereof.



(b) Before any Holder of a Debenture shall be entitled to convert the same, such Holder shall, in the case of Debentures issued in global form, comply
with the procedures of the Depositary in effect at that time, and in the case of Physical Securities, surrender such Debenture, duly endorsed to the Company or in blank, at the office of the Conversion Agent, and shall give written notice to the
Company at said office or place that such Holder elects to convert the same and shall state in writing therein the principal amount of Debentures to be converted and the name or names (with addresses) in which such Holder wishes the certificate or
certificates for Common Stock to be issued.



Before any such
conversion, a Holder also shall pay all funds required, if any, relating to interest on the Debenture, as provided in Section 12.9, and all taxes or duties, if any, as provided in Section 12.8.



If more than one Debenture shall be surrendered for conversion at one time by
the same Holder, the number of full shares of Common Stock which shall be deliverable upon conversion shall be computed on the basis of the aggregate principal amount of the Debentures (or specified portions thereof to the extent permitted thereby)
so surrendered. Subject to Section 12.12 and the next succeeding sentence, Fisher will, as soon as practicable thereafter, issue and the Company shall deliver at said office or place to such Holder of a Debenture, or to such Holders nominee or
nominees, certificates for the number of full shares of Common Stock to which such Holder shall be entitled as aforesaid, together, subject to the last sentence of Section 12.2(a) above, with cash in lieu of any fraction of a share to which such
Holder would otherwise be entitled.



71



---

Neither the Company nor Fisher shall be required to deliver certificates for shares of Common Stock while the stock
transfer books for such stock or the security register are duly closed for any purpose, but certificates for shares of Common Stock shall be issued and delivered as soon as practicable after the opening of such books or security register.



(c) A Debenture shall be deemed to have been converted as of
the close of business on the date of the surrender of such Debenture for conversion as provided above and the satisfaction of the other requirements for conversion, and, if the Company chooses to settle the Conversion Obligation only in Common Stock
or a combination of cash and Common Stock, the person or persons entitled to receive such Common Stock issuable upon such conversion shall be treated for all purposes as the record Holder or Holders of such Common Stock as of the close of business
on such date.



(d) In case any Debenture shall be surrendered
for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Debenture so surrendered, without charge to such Holder (subject to the provisions of Section 12.8
hereof), a new Debenture in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Debenture.



(e) For purposes of calculating the amount of the Common Stock to be delivered pursuant to any conversion under this Article 12, the Common Stock shall be
valued at 100% of the average of the Sale Price for the Common Stock for the five Trading Days ending on the third Trading Day immediately preceding the applicable Conversion Date.



Section 12.3 Adjustments of Conversion Price for Common Stock.



The Conversion Price shall be adjusted from time to time as follows:



(a) In case Fisher shall, at any time or from time to time
while any of the Debentures are outstanding, pay a dividend or make a distribution in shares of Common Stock to all holders of its outstanding shares of Common Stock, then the Conversion Price in effect at the opening of business on the date
following the Record Date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction:



(1) the numerator of which shall be the number of shares of
Common Stock outstanding at the close of business on the Record Date fixed for such determination; and



(2) the denominator of which shall be the sum of such number of shares and the total number of shares constituting such dividend or other
distribution.



Such reduction shall become effective
immediately after the opening of business on the day following the Record Date fixed for such determination. If any



72



---

dividend or distribution of the type described in this Section 12.3(a) is declared but not so paid or made, the
Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared.



(b) In case Fisher shall, at any time or from time to time while any of the Debentures are outstanding, subdivide its outstanding shares of Common Stock
into a greater number of shares of Common Stock, then the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case
Fisher shall, at any time or from time to time while any of the Debentures are outstanding, combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, then the Conversion Price in effect at the opening of
business on the day following the day upon which such combination becomes effective shall be proportionately increased.



Such reduction or increase, as the case may be, shall become effective immediately after the opening of business on the day following the day upon which
such subdivision or combination becomes effective.



(c) In case
Fisher shall, at any time or from time to time while any of the Debentures are outstanding, issue rights or warrants (other than any rights or warrants referred to in Section 12.3(d)) to all or substantially all holders of its shares of Common Stock
entitling them to subscribe for or purchase shares of Common Stock (or securities convertible into shares of Common Stock) at a price per share (or having a conversion price per share) less than the Sale Price on the Business Day immediately
preceding the date of the announcement of such issuance (treating the conversion price per share of the securities convertible into Common Stock as equal to (x) the sum of (i) the price for a unit of the security convertible into Common Stock and
(ii) any additional consideration initially payable upon the conversion of such security into Common Stock divided by (y) the number of shares of Common Stock initially underlying such convertible security), then the Conversion Price shall be
adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect at the opening of business on the date after such date of announcement by a fraction:



(1) the numerator of which shall be the number of shares of
Common Stock outstanding on the close of business on the date of announcement, plus the number of shares or securities which the aggregate offering price of the total number of shares or securities so offered for subscription or purchase (or the
aggregate conversion price of the convertible securities so offered) would purchase at such Sale Price of the Common Stock; and



(2) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date of
announcement, plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible securities so offered are convertible).



73



---

Such adjustment shall become effective immediately after the opening of business on the day following the
date of announcement of such issuance. To the extent that shares of Common Stock (or securities convertible into shares of Common Stock) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or
warrants, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of
Common Stock (or securities convertible into shares of Common Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in
effect if the date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at
less than such Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, the value of such consideration if other than cash,
to be determined by the Board of Directors.



(d) In case Fisher
shall, at any time or from time to time while any of the Debentures are outstanding, by dividend or otherwise, distribute to all or substantially all holders of its shares of Common Stock (including any such distribution made in connection with a
consolidation or merger in which Fisher is the continuing corporation and the Common Stock is not changed or exchanged), cash, shares of its capital stock (other than any dividends or distributions to which Section 12.3(a) applies), evidences of its
Indebtedness or other assets, including securities, but excluding (i) any rights or warrants referred to in Section 12.3(c), (ii) dividends or distributions of stock, securities or other property or assets (including cash) in connection with a
reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.4 applies and (iii) dividends and distributions paid exclusively in cash (such capital stock, evidence of its
indebtedness, cash, other assets or securities being distributed hereinafter in this Section 12.3(d) called the distributed assets), then, in each such case, subject to the third and fourth succeeding paragraphs and the last Section of
this Section 12.3(d), the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date with respect to such
distribution by a fraction:



(1) the numerator
of which shall be the Current Market Price of the Common Stock, less the Fair Market Value on such date of the portion of the distributed assets so distributed applicable to one share of Common Stock (determined on the basis of the number of shares
of Common Stock outstanding on the Record Date)(determined as provided in Section 12.3(g)) on such date; and



74



---

(2) the denominator of which shall be such Current Market Price.



Such reduction shall become effective immediately prior to the opening of business on the day
following the Record Date for such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or
distribution had not been declared.



If the Board of Directors
determines the Fair Market Value of any distribution for purposes of this Section 12.3(d) by reference to the actual or when issued trading market for any distributed assets comprising all or part of such distribution, it must in doing so consider
the prices in such market over the same period (the Reference Period) used in computing the Current Market Price pursuant to Section 12.3(g) to the extent possible, unless the Board of Directors determines in good faith that
determining the Fair Market Value during the Reference Period would not be in the best interest of the Holders.



In the event any such distribution consists of shares of capital stock of, or similar equity interests in, one or more Fisher Subsidiaries (a
Spin-Off), the Fair Market Value of the securities to be distributed shall equal the average of the closing sale prices of such securities on the principal securities market on which such securities are traded for the five
consecutive Trading Days commencing on and including the sixth day of trading of those securities after the effectiveness of the Spin-Off, and the Current Market Price shall be measured for the same period. In the event, however, that an
underwritten initial public offering of the securities in the Spin-Off occurs simultaneously with the Spin-Off, Fair Market Value of the securities distributed in the Spin-Off shall mean the initial public offering price of such securities and the
Current Market Price shall mean the Sale Price for the Common Stock on the same Trading Day.



Rights or warrants distributed by Fisher to all holders of its shares of Common Stock entitling them to subscribe for or purchase shares of Fisher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 shares of Common Stock, shall be deemed not to have been distributed for purposes of this Section 12.3(d) (and no adjustment to the Conversion Price under this Section 12.3(d) will be required) until the occurrence
of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different distributed assets, evidences of indebtedness or other assets,
or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and Record Date with
respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder 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 resulted in an adjustment to the Conversion Price under this Section 12.3(d):



(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 of shares of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of shares of Common Stock as of the date of
such redemption or repurchase; and



75



---

(2) in the case of such rights or warrants which shall have expired or been terminated
without exercise, the Conversion Price shall be readjusted as if such rights and warrants had never been issued.



For purposes of this Section 12.3(d) and Sections 12.3(a), 12.3(b) and 12.3(c), any dividend or distribution to which this Section 12.3(d) is applicable
that also includes (i) shares of Common Stock, (ii) a subdivision or combination of shares of Common Stock to which Section 12.3(b) applies or (iii) rights or warrants to subscribe for or purchase shares of Common Stock to which Section 12.3(c)
applies (or any combination thereof), shall be deemed instead to be:



(1) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants, other than such shares of Common Stock, such subdivision or combination or such rights or warrants
to which Sections 12.3(a), 12.3(b) and 12.3(c) apply, respectively (and any Conversion Price reduction required by this Section 12.3(d) with respect to such dividend or distribution shall then be made), immediately followed by



(2) a dividend or distribution of such shares of Common
Stock, such subdivision or combination or such rights or warrants (and any further Conversion Price reduction required by Sections 12.3(a), 12.3(b) and 12.3(c) with respect to such dividend or distribution shall then be made), except:



(A) the Record Date of such dividend or distribution shall
be substituted as (i) the date fixed for the determination of stockholders entitled to receive such dividend or other distribution, Record Date fixed for such determinations and Record Date within the meaning of
Section 12.3(a), (ii) the day upon which such subdivision becomes effective and the day upon which such combination becomes effective within the meaning of Section 12.3(b), and (iii) as the date fixed for the



76



---

determination of stockholders entitled to receive such rights or warrants, the Record Date
fixed for the determination of the stockholders entitled to receive such rights or warrants and such Record Date within the meaning of Section 12.3(c); and



(B) any shares of Common Stock included in such dividend or distribution shall not be deemed
outstanding at the close of business on the date fixed for such determination within the meaning of Section 12.3(a) and any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination
shall be disregarded in connection with such dividend or distribution.



In the event of any distribution referred to in this Section 12.3(d) in which (1) the Fair Market Value (as determined by the Board of Directors) of such distribution applicable to one share of Common Stock (determined as provided above)
equals or exceeds the average of the Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Record Date for such distribution or (2) the average of the Sale Prices of the Common Stock over the ten consecutive
Trading Day period ending on the Record Date for such distribution exceeds the Fair Market Value of such distribution by less than $1.00, then, in each such case, in lieu of an adjustment to the Conversion Price, adequate provision shall be made so
that each Holder shall have the right to receive upon conversion of a Debenture, in addition to shares of Common Stock, the kind and amount of such distribution such Holder would have received had such Holder converted such Debenture immediately
prior to the Record Date for determining the shareholders entitled to receive the distribution.



In the event of any distribution referred to in Section 12.3(c) or 12.3(d), where, in the case of a distribution described in Section 12.3(d), the Fair
Market Value of such distribution per share of Common Stock (as determined by the Board of Directors) exceeds 5% of the Sale Price of a share of Common Stock on the Business Day immediately preceding the declaration date for such distribution, then,
if such distribution would also trigger a conversion right under Section 12.1(b) or the Debentures are otherwise convertible pursuant to this Article 12, the Company will be required to give notice to the Holders of Debentures at least 20 days prior
to the Ex-Dividend Time for the distribution and, upon the giving of notice, the Debentures may be surrendered for conversion at any time on and after the date that the Company gives notice to the Holders of such conversion right, until the close of
business on the Business Day prior to the Ex-Dividend Time or Fisher announces that such distribution will not take place. No adjustment to the Conversion Price or the ability of a Holder of a Debenture to convert will be made if the Holder will
otherwise participate in such distribution without conversion.



(e) In case Fisher shall, at any time or from time to time while any of the Debentures are outstanding, by dividend or otherwise, distribute to all or substantially all holders of shares of its Common Stock cash (excluding any dividend or
distribution in connection with the liquidation, dissolution or winding up of Fisher, whether voluntary or



77



---

involuntary), then, in such case, the Conversion Price shall be reduced so that the same shall equal the rate determined
by multiplying the Conversion Price in effect on the applicable Record Date by a fraction,



(1) the numerator of which shall be the Current Market Price on such Record Date less the full amount of cash so distributed as applicable
to one share of Common Stock; and



(2) the
denominator of which shall be the Current Market Price on such Record Date,



such adjustment to be effective immediately prior to the opening of business on the day following the Record Date; provided that if the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than
the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion the amount of cash such holder would have received had such Holder
converted each Security on the Record Date. If such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such dividend or distribution had not been
declared.



(f) In case a tender offer made by Fisher or any of
its Subsidiaries for all or any portion of the shares of Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the
terms of the tender offer) of shares tendered) of an aggregate consideration having a Fair Market Value (as determined by the Board of Directors) that combined together with:



(1) the aggregate amount of the cash, plus the Fair Market Value (as determined by the Board of Directors),
as of the expiration of such tender offer, of consideration payable in respect of any other tender offers, by Fisher or any of its Subsidiaries for all or any portion of the shares of Common Stock expiring within the 12 months preceding the
expiration of such tender offer and in respect of which no adjustment pursuant to this Section 12.3(f) has been made; and



(2) the aggregate amount of any distributions to all holders of shares of Common Stock made exclusively in cash within 12 months preceding
the expiration of such tender offer and in respect of which no adjustment pursuant to Section 12.3(e) has been made;



exceeds 10% of the product of the Current Market Price of the Common Stock as of the last time (the Expiration Time) tenders could have been made
pursuant to such tender offer (as it may be amended), times the number of shares of Common Stock outstanding (including any tendered shares) on the Expiration Time (such excess, the Excess Amount), then, and in each such case,
immediately prior to the opening of business on the Business Day after the date of the Expiration Time, the Conversion Price shall be



78



---

adjusted 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 date of the Expiration Time by a fraction:



(1) the numerator of which shall be the (x) the product of (i) the number of shares of Common Stock outstanding (including any tendered
shares) at the Expiration Time and (ii) the Current Market Price of the Common Stock at the Expiration Time, less (y) the Excess Amount; and



(2) the denominator shall be the product of the number of shares of Common Stock outstanding (including any tendered shares) at the
Expiration Time and the Current Market Price of the Common Stock at the Expiration Time.



Such reduction (if any) shall become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that Fisher is obligated to purchase shares pursuant to any such
tender offer, but Fisher is permanently prevented by applicable law from effecting any such purchases or all or a portion of such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in
effect if such (or such portion of the) tender offer had not been made. If the application of this Section 12.3(f) 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 12.3(f).



(g) For purposes of this Article 12, the
following terms shall have the meanings indicated:



Current Market Price on any date means the average of the daily Sale Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to such date; provided, however, that if:



(1) the ex date (as hereinafter
defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.3(a), (b), (c), (d), (e) or (f) occurs during such ten consecutive Trading Days,
the Sale Price for each Trading Day prior to the ex date for such other event shall be adjusted by dividing such Sale Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event;



(2) the ex date for any event
(other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.3(a), (b), (c), (d), (e) or (f) occurs on or after the ex date for the issuance or
distribution requiring such computation and prior to the day in question, the Sale Price for each Trading Day on and after the ex date for such other event shall be



79



---

adjusted by dividing such Sale Price by the reciprocal of the fraction by which the Conversion Price is
so required to be adjusted as a result of such other event; and



(3) the ex date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso,
the Sale Price for each Trading Day on or after such ex date shall be adjusted by adding thereto the amount of any cash and the Fair Market Value (as determined by the Board of Directors in a manner consistent with any determination of
such value for purposes of Section 12.3(d), (e) or (f)) of the evidences of Indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such ex
date.



For purposes of any computation under Section 12.3(f), if the
ex date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.3(a), (b), (c), (d), (e) or (f) occurs on or after the Expiration Time for the
tender or exchange offer requiring such computation and prior to the day in question, the Sale Price for each Trading Day on and after the ex date for such other event shall be adjusted by dividing such Sale Price by the reciprocal of
the fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term ex date, when used:



(1) with respect to any issuance or distribution, means the first date on which the shares of Common Stock
trade regular way on the relevant exchange or in the relevant market from which the Sale Price was obtained without the right to receive such issuance or distribution;



(2) with respect to any subdivision or combination of shares of Common Stock, means the first date on which
the shares of Common Stock trade regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective; and



(3) with respect to any tender or exchange offer, means the first date on which the shares of Common Stock trade regular way on such
exchange or in such market after the Expiration Time of such offer.



Notwithstanding the foregoing, whenever successive adjustments to the Conversion Price are called for pursuant to this Section 12.3, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate
the intent of this Section 12.3 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.



Fair Market Value shall mean the amount which a willing buyer would pay a willing seller in an arms length transaction (as
determined by the Board of Directors, whose determination shall be conclusive).



80



---

Record Date shall mean, with respect to any dividend, distribution or other
transaction or event in which the holders of shares of Common Stock have the right to receive any cash, securities or other property or in which the shares of Common Stock (or other applicable security) are exchanged for or converted into any
combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or
otherwise).



(h) The Company shall be entitled to make such
additional reductions in the Conversion Price, in addition to those required by Sections 12.3(a), (b), (c), (d), (e) and (f), as shall be necessary in order that any dividend or distribution of Common Stock, any subdivision, reclassification or
combination of shares of Common Stock or any issuance of rights or warrants referred to above shall not be taxable to the holders of Common Stock for United States federal income tax purposes.



(i) To the extent permitted by applicable law, the Company may, from time to
time, reduce the Conversion Price by any amount for any period of time, if such period is at least 20 days and the reduction is irrevocable during the period. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company
shall mail to the Trustee and each Holder at the address of such Holder as it appears in the register of the Debentures maintained by the Registrar, at least 15 days prior to the date the reduced Conversion Price takes effect, a notice of the
reduction stating the reduced Conversion Price and the period during which it will be in effect.



(j) In any case in which this Section 12.3 shall require that any adjustment be made effective as of or retroactively immediately following a Record Date,
Fisher may elect to defer (but only for five Trading Days following the filing of the statement referred to in Section 12.5) issuing to the Holder of any Debenture converted after such Record Date the shares of Common Stock issuable upon such
conversion over and above the shares of Common Stock issuable upon such conversion on the basis of the Conversion Price prior to adjustment; provided, however, that Fisher shall deliver to such Holder a due bill or other appropriate
instrument evidencing such Holders right to receive such additional shares upon the occurrence of the event requiring such adjustment.



(k) All calculations under this Section 12.3 shall be made to the nearest cent or one hundredth of a share, with one half cent and 0.005 of a share,
respectively, being rounded upward. Notwithstanding any other provision of this Section 12.3, the Company shall not be required to make any adjustment of the Conversion Price unless such adjustment would require an increase or decrease of at least
1% of such price; provided that the Company must carry forward any adjustments that are less than 1% of the Conversion Price and make such carried forward adjustments, regardless of whether the aggregate adjustment is less than 1%, within one year
of the first such adjustment carried forward. Any adjustments under this Section 12.3 shall be made successively whenever an event requiring such an adjustment occurs.



81



---

(l) In the event that at any time, as a result of an adjustment made pursuant to this Section 12.3, the
Holder of any Debenture thereafter surrendered for conversion shall become entitled to receive any shares of stock of Fisher other than shares of Common Stock into which the Debentures originally were convertible, the Conversion Price of such other
shares so receivable upon conversion of any such Debenture 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 subparagraphs (a)
through (k) of this Section 12.3, and the provisions of Sections 12.1, 12.2 and 12.4 through 12.9 with respect to the Common Stock shall apply on like or similar terms to any such other shares and the determination of the Board of Directors as to
any such adjustment shall be conclusive.



(m) No adjustment
shall be made pursuant to this Section 12.3 (i) if the effect thereof would be to reduce the Conversion Price below the par value (if any) of the Common Stock or (ii) if the Holders of the Debentures may participate in the transaction that would
otherwise give rise to an adjustment pursuant to this Section 12.3.



Unless otherwise specified, determinations required to be made pursuant to this Article 12 by the Board of Directors shall be made by the Board of Directors of Fisher and all references to the Board of Directors in this Article 12 shall be
deemed to be the Board of Directors of Fisher.



Section 12.4
Consolidation or Merger of Fisher.



If any of the
following events occurs, namely:



(1) any
reclassification or change of the outstanding Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination);



(2) any merger, consolidation, statutory share exchange or
combination of Fisher with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock; or



(3) any sale or conveyance of the properties
and assets of Fisher as, or substantially as, an entirety to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in
exchange for such Common Stock;



Fisher or the successor or purchasing
corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture, if such supplemental indenture is then
required to so comply) providing that such Debentures shall be convertible into the kind and amount of shares of stock and other securities or property or



82



---

assets (including cash) which such Holder would have been entitled to receive upon such reclassification, change, merger,
consolidation, statutory share exchange, combination, sale or conveyance had such Debentures been converted into Common Stock immediately prior to such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or
conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance
(provided, that if the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance is not the same for each share of Common Stock in respect of which such
rights of election shall not have been exercised (Non-Electing Share), then for the purposes of this Section 12.4, the kind and amount of securities, cash or other property receivable upon such merger, consolidation, statutory share
exchange, sale or conveyance for each Non-Electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-Electing Shares). Such supplemental indenture shall provide for adjustments that shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article 12. If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other
securities and assets receivable thereupon by a holder of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change,
merger, consolidation, statutory share exchange, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders
of the Debentures as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the repurchase rights set forth in Article 11 hereof.



The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Debentures maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture.



The above provisions
of this Section 12.4 shall similarly apply to successive reclassifications, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances.



If this Section 12.4 applies to any event or occurrence, Section 12.3 shall not apply.



Fisher shall not enter into a transaction of the type described in this
Section 12.4 unless the terms of this Section 12.4 are complied with in full.



83

Section 12.5 Notice of Adjustment.



Whenever an adjustment in the Conversion Price with respect to the Debentures is required:



(1) the Company shall forthwith place on file with the
Trustee and any Conversion Agent for such securities a certificate of the Treasurer of the Company, stating the adjusted Conversion Price determined as provided herein and setting forth in reasonable detail such facts as shall be necessary to show
the reason for and the manner of computing such adjustment; and



(2) a notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price shall forthwith be given by the Company or, at the Companys written request, by the Trustee in the
name and at the expense of the Company, to each Holder in the manner provided in Section 14.2. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice.



Section 12.6 Notice in Certain Events.



In case:



(1) of a consolidation or merger to which Fisher is a party and for which approval of any stockholders of
Fisher is required, or of the sale or conveyance to another Person or entity or group of Persons or entities acting in concert as a partnership, limited partnership, syndicate or other group (within the meaning of Rule 13d-3 under the Exchange Act)
of all or substantially all of the property and assets of Fisher; or



(2) of the voluntary or involuntary dissolution, liquidation or winding up of Fisher; or



(3) of any action triggering an adjustment of the Conversion Price referred to in clauses (x) or (y) below;



then, in each case, Fisher shall cause to be filed with the Trustee and the Conversion
Agent, and shall cause to be given, to the Holders of the Debentures in the manner provided in Section 14.2, at least 15 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the
purpose of any distribution or grant of rights or warrants triggering an adjustment to the Conversion Price pursuant to this Article 12, or, if a record is not to be taken, the date as of which the holders of record of Common Stock entitled to such
distribution, rights or warrants are to be determined, or (y) the date on which any reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up triggering an adjustment to the Conversion Price pursuant to this
Article 12 is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to



84



---

exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation,
merger, sale, conveyance, dissolution, liquidation or winding up.



Failure to give such notice or any defect therein shall not affect the legality or validity of the proceedings described in clause (1), (2) or (3) of this Section 12.6.



Section 12.7 Fisher to Reserve Stock; Registration; Listing.



(a) Fisher shall, in accordance with the laws of the State of Delaware, at
all times reserve and keep available, free from preemptive rights, out of its authorized but unissued shares of Common Stock, for the purpose of effecting the conversion of the Debentures, such number of its duly authorized shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all Debentures then Outstanding into such Common Stock at any time (assuming that, at the time of the computation of such number of shares or securities, all such Debentures would be
held by a single Holder); provided, however, that nothing contained herein shall preclude Fisher from satisfying its obligations in respect of the conversion of the Debentures by delivery of purchased shares of Common Stock which are then held in
the treasury of Fisher. Fisher covenants that all shares of Common Stock that may be issued upon conversion of Debentures will upon issue be fully paid and nonassessable and free from all liens and charges and, except as provided in Section 12.8,
taxes with respect to the issue thereof.



(b) If any shares of
Common Stock which would be issuable upon conversion of Debentures hereunder require registration with or approval of any governmental authority before such shares or securities may be issued upon such conversion, Fisher will in good faith and as
expeditiously as possible endeavor to cause such shares or securities to be duly registered or approved, as the case may be. Fisher further covenants that so long as the Common Stock shall be listed on the New York Stock Exchange, Fisher will, if
permitted by the rules of such exchange, list and keep listed all Common Stock issuable upon conversion of the Debentures, and Fisher will endeavor to list the shares of Common Stock required to be delivered upon conversion of the Debentures prior
to such delivery upon any other national securities exchange upon which the outstanding Common Stock is listed at the time of such delivery.



Section 12.8 Taxes on Conversion.



The issue of stock certificates on conversion of Debentures shall be made without charge to the converting Holder for any documentary, stamp or similar
issue or transfer taxes in respect of the issue thereof, and Fisher shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of
Debentures pursuant hereto. Fisher shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue or delivery of shares of Common Stock or the portion, if any, of the Debentures which are
not so converted in a name other than that in which the Debentures so converted were registered, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to Fisher the amount of such tax or has
established to the satisfaction of Fisher that such tax has been paid.



85



---

Section 12.9 Conversion After Record Date.



Except as provided below, if any Debentures are surrendered for conversion
on any day other than an Interest Payment Date, the Holder of such Debentures shall not be entitled to receive any Interest (including Contingent Interest) that has accrued on such Debentures since the prior Interest Payment Date. By delivery to the
Holder of the number of shares of Common Stock or other consideration issuable upon conversion in accordance with this Article 12, any accrued and unpaid Interest (including Contingent Interest) on such Debentures will be deemed to have been paid in
full.



If any Debentures are surrendered for conversion
subsequent to the Record Date preceding an Interest Payment Date but on or prior to such Interest Payment Date, the Holder of such Debentures at the close of business on such Record Date shall receive the Interest (including Contingent Interest)
payable on such Debentures on such Interest Payment Date notwithstanding the conversion thereof. Debentures surrendered for conversion during the period from the close of business on any Record Date preceding any Interest Payment Date to the opening
of business on such Interest Payment Date shall (except in the case of Debentures which have been called for redemption on a Redemption Date within such period) be accompanied by payment by Holders, for the account of the Company, in New York
Clearing House funds or other funds of an amount equal to the Interest (including Contingent Interest) payable on such Interest Payment Date on the Debentures being surrendered for conversion. Except as provided in this Section 12.9, no adjustments
in respect of payments of Interest (including Contingent Interest) on Debentures surrendered for conversion or any dividends or distributions or interest on the Common Stock issued upon conversion shall be made upon the conversion of any Debentures.



Section 12.10 Determinations Final.



Any determination that Fisher, the Company or their respective Boards of
Directors must make pursuant to this Article 12 shall be conclusive if made in good faith and in accordance with the provisions of this Article 12, absent manifest error, and set forth in a Board Resolution.



Section 12.11 Responsibility of Trustee for Conversion
Provisions.



The Trustee has no duty to determine
when an adjustment under this Article 12 should be made, how it should be made or what it should be. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Debentures. The Trustee shall
not be responsible for any failure of the Company or Fisher to comply with this Article 12. Each Conversion Agent other than the Company or Fisher shall have the same protection under this Section 12.11 as the Trustee.



86



---

The rights, privileges, protections, immunities and benefits given to the Trustee under this Indenture
including, without limitation, its rights to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Paying Agent or Conversion Agent acting hereunder.



Section 12.12 Payment of Cash in Lieu of Common Stock.



If a Holder elects to convert all or any portion of a Debenture into shares
of Common Stock as set forth in Section 12.1 and delivers an irrevocable conversion notice, together, if the Debentures are in certificated form, with the certificated Debenture, as set forth in Section 12.2, the Company may choose to satisfy all or
any portion of its Conversion Obligation in cash or a combination of cash and Common Stock; provided, however, that the Company has the unilateral right, exercisable at any time, to deliver an Officers Certificate of the Company to the Trustee
and notice to the Holders, each stating that it shall be thereafter obligated to satisfy certain of its Conversion Obligation in cash. Within two Trading Days following the Conversion Date, the Company will notify such Holder through the Conversion
Agent of the Companys election to deliver Common Stock or to pay cash in lieu of delivery of some or all of the shares of Common Stock and, if applicable, the dollar amount per $1,000 principal amount of Debentures to be satisfied in cash
(which must be expressed either as 100% of the Conversion Obligation or as a fixed dollar amount) (such amount of cash, the Cash Amount) unless the Company has previously informed Holders of its election in connection with an optional
redemption of Debentures in accordance with Section 10.4 of this Indenture. Settlement amounts will be computed as follows:



(a) 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:



(1) a number equal to (x) the
aggregate principal amount of Debentures to be converted, divided by (y) the then applicable Conversion Price; and



(2) the average Sale Price of the Common Stock during the Cash Settlement Averaging Period; and



(b) if the Company elects to satisfy a fixed amount (but not all) of the
Conversion Obligation in cash, the Company will deliver to such Holder, per $1,000 principal amount of Debentures converted:



(1) the Cash Amount; and



87



---

(2) a number of shares of Common Stock equal to the sum, for each Trading Day of the Cash
Settlement Averaging Period, of the greater of (i) zero and (ii) a number of shares of Common Stock equal to a fraction:



(A) the numerator of which equals the (x) the product of the Sale Price of the Common Stock on such Trading Day multiplied by the
Conversion Rate minus (y) the Cash Amount; and



(B) the denominator of which equals the product of the Sale Price of Common Stock on such Trading Day multiplied by the number of Trading Days in the Cash Settlement Averaging Period;



provided, however, that the Company will pay cash in lieu of fractional shares of Common
Stock in accordance with Section 12.2.



Section 12.13
Unconditional Right of Holders to Convert.



Notwithstanding any other provision in this Indenture, the Holder of any Debenture shall have the right, which is absolute and unconditional, to convert its Debenture in accordance with this Article 12 and to bring an action for the
enforcement of any such right to convert, and such rights shall not be impaired or affected without the consent of such Holder.



ARTICLE 13



GUARANTEES



Section 13.1 Future Subsidiary Guarantees.



(a) After the date of this Indenture, the Company shall cause each Subsidiary (including any newly created or acquired Subsidiary) of the Company which becomes a guarantor under the Credit Agreement to promptly execute and deliver to the
Trustee a Guarantee substantially in the form of the Supplemental Indenture attached as Exhibit F hereto pursuant to which such Subsidiary shall unconditionally guarantee, on a joint and several basis, the full and prompt payment of the principal,
Interest (including Contingent Interest), if any, with respect to the Debentures.



Section 13.2 Releases.



(a) Upon the designation of any of the Guarantors (other than Fisher) as an Excluded Subsidiary, such Guarantor shall be released and relieved of its obligations under this Indenture. Upon delivery by the Company to the Trustee of an
Officers Certificate of the Company and an Opinion of Counsel of the Company to the effect that such designation of such Guarantor as an Excluded Subsidiary was made by the Company in accordance with the provisions of this Indenture, the
Trustee shall execute any documents reasonably required in order to evidence the release of such Guarantor from its obligations under its Guarantee. The Guarantors not released from their obligations under the Guarantees shall remain liable for the
full amount of principal of and Interest (including Contingent Interest) on the Debentures and for the other obligations of any of the Guarantors under this Indenture.



88

Section 13.3 Fisher Guarantee.



(a) Upon the earlier of (1) the date on which the obligation of the Company to file periodic reports with the Commission
pursuant to Section 13 or 15(d) of the Exchange Act is terminated or suspended and (2) February 23, 2010 (such earlier date, the Effective Date), Fisher hereby agrees as follows:



(1) Fisher unconditionally guarantees to each Holder of a
Debenture authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, regardless of the validity and enforceability of the Indenture, the Securities or the Obligations of the Company under this Indenture or the
Securities, that:



(A) the principal of, and
Interest (including Contingent Interest) on and any other amounts in respect of the Debentures will be promptly paid in full when due, whether at maturity, by acceleration, redemption, repurchase, conversion or otherwise, and interest on the overdue
principal of, Interest (including Contingent Interest) on the Debentures, to the extent lawful, and all other Obligations of the Company, including the Cash Amount, to the Holders or the Trustee thereunder or under this Indenture will be promptly
paid in full, all in accordance with the terms thereof; and



(B) in case of any extension of time for payment or renewal of any Debentures or any of such other Obligations, that the same will be promptly paid in full when due in accordance with the terms of the extension or
renewal, whether at stated maturity, by acceleration or otherwise.



(2) Notwithstanding the foregoing, in the event that the Guarantee set forth in paragraph (a)(1) of this Section 13.3 (the Fisher Guarantee) would constitute or result in a violation of any
applicable fraudulent conveyance or similar law of any relevant jurisdiction, the liability of Fisher under this Indenture shall be reduced to the maximum amount permissible under such fraudulent conveyance or similar law.



(b) Execution and Delivery of Guarantee.



(1) To evidence the Fisher Guarantee, Fisher hereby agrees
that a notation of such Fisher Guarantee (in the form set forth in Exhibit A hereto) shall be endorsed on each Debenture authenticated and delivered by the Trustee on and after the date hereof, which Fisher Guarantee will be effective as of the
Effective Date without any action being taken by any person.



(2) Notwithstanding the foregoing, Fisher hereby agrees that the Fisher Guarantee shall be effective as of the Effective Date, and thereafter remain in full force and effect notwithstanding any failure to endorse on
each Debenture a notation of such Fisher Guarantee.

---

(3) If an Officer of Fisher who endorses the notation of the Fisher Guarantee on any
Debenture no longer holds that office at the time the Trustee authenticates the Debenture on which the Fisher Guarantee is endorsed, the Fisher Guarantee shall be valid nevertheless.



(4) The delivery of any Debenture by the Trustee, after the authentication thereof under the Indenture,
shall constitute due delivery of the Fisher Guarantee set forth in this Indenture on behalf of Fisher as of the Effective Date.



(5) Fisher hereby agrees that its obligations hereunder shall be unconditional, regardless of the validity, regularity or enforceability
of the Securities or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Debentures with respect to any provisions of the Securities or the Indenture, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor.



(6) Fisher hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy
of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that the Fisher Guarantee made pursuant to this Indenture will not be discharged except by complete performance of
the Obligations contained in the Securities and the Indenture.



(7) If any Holder or the Trustee is required by any court or otherwise to return to the Company or the Guarantors, or any Custodian, Trustee, liquidator or other similar official acting in relation to either the
Company or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Fisher Guarantee made pursuant to this Indenture, to the extent theretofore discharged, shall be reinstated in full force and effect.



(8) Fisher hereby agrees that it shall not be entitled to
any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Fisher further agrees that, as between Fisher and the other Guarantors, if any, on the
one hand, and the Holders and the Trustee, on the other hand:



(A) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 4 of the Indenture for the



90



---

purposes of the Fisher Guarantee made pursuant to this Indenture, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby; and



(B) in the event of any declaration of acceleration of such Obligations as provided in Article 4 of the Indenture, such Obligations
(whether or not due and payable) shall forthwith become due and payable by Fisher for the purpose of the Fisher Guarantee made pursuant to this Indenture.



(c) Fisher shall have the right to seek contribution from any other non-paying Guarantor so long as the exercise of such right does not impair the rights
of the Holders or the Trustee under the Guarantees made pursuant to this Indenture.



(d) No Recourse Against Others. No past, present or future director, officer, employee, incorporator, stockholder or agent of Fisher, as such, shall have any liability for any obligations of the Company or any
Guarantor under the Debentures, any Guarantees, this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Debentures by accepting a Debentures waives and releases all such
liability. The waiver and release are part of the consideration for issuance of the Debentures. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Commission that such a waiver is
against public policy.

thereby) are herein sometimes referred to as the Act of the Holders of Debentures signing such instrument or instruments and so voting at such meeting. Proof of execution of any such instrument or of a writing appointing any such agent

In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may
certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.



Any certificate or opinion of an Officer of the Company or Fisher may be
based, insofar as it relates to legal matters, upon an Opinion of Counsel of the Company or Fisher, unless such Officer knows, or in the exercise of reasonable care should know, that the Opinion of Counsel of the Company or Fisher with respect to
the matters upon which such certificate or opinion is based is erroneous. Any such Opinion of Counsel of the Company or Fisher may be based, insofar as it relates to factual matters, upon a certificate or representations by, an Officer or Officers

that the certificate or representations with respect to such matters are erroneous.



Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.



Upon any application or request by
the Company or Fisher to the Trustee to take any action under any provision of this Indenture, the Company or Fisher, as applicable, shall furnish to the Trustee an Officers Certificate of the Company or Fisher, as applicable, stating that all
conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel of the Company or Fisher, as applicable, stating that in the opinion of such Counsel all such conditions
precedent, if any, have been complied with, except that in the case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Indenture relating to such particular application
or request, no additional certificate or opinion need be furnished; provided however, that, at any time that an Opinion of Counsel of the Company or Fisher, as applicable, is required to be delivered hereunder, the opining counsel may, with the
consent of the Trustee, deliver the Opinion of Counsel of the Company or Fisher, as applicable, in question addressed to a party other than the Trustee with text to the effect that the Trustee may rely on such opinion rather than by delivering a
separate Opinion of Counsel of the Company or Fisher, as applicable, to the Trustee directly.

conversion of the Debenture, need not be made at such Place of Payment or Place of Conversion on such day, but may be made on the next succeeding Business Day at such Place of Payment or Place of Conversion with the same force and effect as if made
on the Interest Payment Date, Redemption Date, Repurchase Date or at the Stated Maturity or on such last day for conversion; provided, however, that in the case that payment is made on such succeeding Business Day, no interest shall accrue on the

[Reverse of Debenture]



APOGENT TECHNOLOGIES INC.



Floating Rate Convertible Senior Debentures due 2033



Section 1. General. This Debenture is one of a duly authorized issue of Debt Securities of the Company (herein called the Debentures),
issued under an Indenture, dated as of August 3, 2004, as amended or supplemented from time to time (the Indenture), among the Company, Fisher Scientific International Inc. (Fisher) and The Bank of New York, as Trustee
(herein called the Trustee, which term includes any successor trustee under the Indenture), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of
the Company, Fisher, the Trustee and the Holders of the Debentures and of the terms upon which the Debentures are, and are to be, authenticated and delivered. The terms, conditions and provisions of the Debentures are those stated in the Indenture,
those made a part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, and those set forth in this Debenture. To the extent that the terms, conditions and other provisions of this Debenture modify, supplement or are
inconsistent with those of the Indenture, then the terms, conditions and other provisions of the Indenture shall govern. All terms used in this Debenture that are defined in the Indenture shall have the meanings assigned to them in the Indenture.



Section 2. Interest and Payments. This Debenture will
bear interest from August 3, 2004 or from and including the most recent Interest Payment Date to which Interest (including Contingent Interest) has been paid or duly provided for, as the case may be, at a per annum rate which will equal 3-month
LIBOR, adjusted quarterly on each Interest Adjustment Date, as defined below, minus a spread of 125 basis points, which spread may be reset upon the occurrence of a Reset Transaction as described in the Indenture. Notwithstanding the foregoing,
Interest for the initial interest period commencing August 3, 2004 shall accrue at the rate of 0.27% per annum. In no event shall any quarterly adjustments of the interest rate or resetting of the spread result in the interest rate borne by the
Debentures being less than zero.



The Company will pay interest
quarterly in arrears on March 15, June 15, September 15 and December 15 of each year, beginning September 15, 2004, unless any such Interest Payment Date (other than an Interest Payment Date at maturity) would otherwise be a day that is not a
business day, in which case the interest payment date will be postponed to the next succeeding business day (except if that business day falls in the next succeeding calendar month, that interest payment date will be the immediately preceding
business day). If the maturity date of the Debentures is a day that is not a business day, all payments to be made on such day will be made on the next succeeding business day, with the same force and effect as if made on the due date, and no
additional interest will be payable as a result of such a delay in payment.



On each Interest Determination Date for the Debentures, or as soon thereafter as practicable, the Calculation Agent shall determine the applicable Interest Rates as provided for and contemplated by the Debentures. The
Calculation Agent shall



5



---

notify the Company and the Trustee of such Interest Rates as soon as reasonably practicable after the determination
thereof. The Calculation Agent shall perform such other actions and undertake such other duties of the Calculation Agent as are described in the Indenture to be performed or undertaken by the Calculation Agent. The Calculation Agent shall not be
responsible for calculating Contingent Interest.



The term
3-month LIBOR as determined by the Calculation Agent means, with respect to any Interest Determination Date:



(1) the rate for 3-month deposits in United States dollars commencing on the related Interest Adjustment Date, that appears on the
Moneyline Telerate Page 3750 (as described below) as of 11:00 A.M., London time, on the Interest Determination Date, unless fewer than two such offered rates so appear; or



(2) if fewer than two offered rates appear, or no rate appears, as the case may be, on the particular
Interest Determination Date on the Moneyline Telerate Page 3750, the rate calculated by the Calculation Agent of at least two offered quotations obtained by the calculation agent after requesting the principal London offices of each of four major
reference banks in the London interbank market to provide the Calculation Agent with its offered quotation for deposits in United States dollars for the period of three months, commencing on the related interest adjustment date, to prime banks in
the London interbank markets at approximately 11:00 A.M., London time, on that Interest Determination Date and in a principal amount that is representative for a single transaction in United States dollars in that market at that time; or



(3) if fewer than two offered quotations referred to in
clause (2) are provided as requested, the rate calculated by the Calculation Agent as the arithmetic mean of the rates quoted at approximately 11:00 A.M., New York time, on the particular interest determination date by three major banks (which will
not include our affiliates) in The City of New York selected by the Calculation Agent for loans in United States dollars to leading European banks for a period of three months and in a principal amount that is representative for a single transaction
in United States dollars in that markets at that time; or



(4) if the banks so selected by the Calculation Agent are not quoting as mentioned in clause (3), 3-month LIBOR in effect immediately prior to the particular Interest Determination Date.



The term Interest Determination Date means the second
London banking day preceding the related Interest Adjustment Date.



The term Interest Adjustment Date means March 15, June 15, September 15 and December 15 of each year; provided that, if any Interest Adjustment Date would otherwise be a day that is not a Business Day, such Interest
Adjustment Date shall be postponed to the next succeeding Business Day, except if such Business Day falls in the next succeeding calendar month, such Interest Adjustment Date will be the immediately preceding Business Day.



6



---

The term London banking day means a day on which commercial banks are open for
business, including dealings in United States dollars, in London.



The term Moneyline Telerate Page 3750 means the display on Moneyline Telerate (or any successor service) on such page (or any other page as may replace such page on such service) for the purpose of displaying the London
interbank rates of major banks for United States dollars.



In
addition, Contingent Interest will accrue on this Debenture during any quarterly interest period, commencing with the quarterly interest period beginning December 15, 2009, under the conditions specified in the Indenture at an amount equal to
0.0625% of the average Trading Price of the Debentures over the measuring period triggering the contingent interest payment.



Interest on this Debenture, including Contingent Interest, will be payable on the Interest Payment Date or Interest Payment Dates as specified on the face
hereof and, in either case, at Maturity. Except as provided below, Interest (including Contingent Interest) will be paid (i) if this Debenture is represented by one or more Global Securities, to DTC in immediately available funds, (ii) if this
Debenture is represented by one or more certificated Debentures by check mailed to the Holders of such Debentures unless, in the case of Holders of certificated Debentures having a principal amount of more than $5,000,000, such Holders shall have
made written application to the Registrar not later than the relevant Regular Record Date requesting payment by wire transfer, in which case payment shall be made by wire transfer in immediately available funds. Principal will be paid (i) if this
Debenture is represented by one or more Global Securities, to DTC in immediately available funds or (ii) if this Debenture is represented by one or more certificated Debentures, at our office or agency in New York City, which initially will be the
office or agency of the Trustee in New York City.



Payments on
this Debenture with respect to any Interest Payment Date or Maturity will include Interest (including Contingent Interest) accrued from and including the original date of issuance, or from and including the most recent Interest Payment Date to which
interest has been paid or duly provided for, to but excluding such Interest Payment Date or Maturity, except as may otherwise be provided in the Indenture. Interest (including Contingent Interest) on the Debentures shall be computed on the basis of
the actual number of days for which Interest is payable in the relevant interest period, divided by 360.



Except as provided below, if any Debenture is surrendered for conversion on any day other than an Interest Payment Date, the Holder of such Debenture
shall not be entitled to receive any Interest (including Contingent Interest) that has accrued on such Debenture since the prior Interest Payment Date. By delivery to the Holder of the number of shares of Common Stock or other consideration issuable
upon conversion in accordance with Indenture, any accrued and unpaid Interest (including Contingent Interest) on such Debenture shall be deemed to have been paid in full.

If any Debenture is converted subsequent to the Regular Record Date preceding an Interest Payment Date
but on or prior to such Interest Payment Date (except Debentures called for redemption on a Redemption Date between such Regular Record Date and Interest Payment Date), the Holder of such Debenture at the close of business on such Regular Record
Date shall be entitled to receive the Interest (including Contingent Interest) payable on such Debenture on such Interest Payment Date notwithstanding the conversion thereof. Any Debenture converted during the period from the close of business on
any Regular Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall (except in the case of Debentures which have been called for redemption on a Redemption Date within such period) be
accompanied by payment in New York Clearing House funds or other funds of an amount equal to the Interest (including Contingent Interest) payable on such Interest Payment Date on the Debenture being surrendered for conversion. Except as provided in
this Section 2 or in the Indenture, no adjustments in respect of payments of Interest (including Contingent Interest) on any Debenture surrendered for conversion or any dividends or distributions or Interest (including Contingent Interest) on the
Common Stock issued upon conversion shall be made upon the conversion of any Debenture.



All percentages resulting from any calculation with respect Interest (including Contingent Interest) will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point (with five one-millionths
of a percentage point being rounded upward) and all dollar amounts used in or resulting from any such calculation with respect to this Debenture will be rounded to the nearest cent (with one-half cent being rounded upward).



If an Interest Payment Date or Maturity for this Debenture falls on a day
that is not a Business Day, payment of principal and Interest (including Contingent Interest) to be made on such day with respect to this Debenture will be made on the next succeeding day that is a Business Day (except if that Business Day falls in
the next succeeding calendar month, that Interest Payment Date will be the immediately preceding Business Day) and if the date of Maturity is a day that is not a Business Day, all payments to be made on such day will be made on the next succeeding
Business Day, with the same force and effect as if made on the due date, and no additional interest will be payable as a result of such a delay in payment.



Section 3. Redemption. This Debenture is subject to redemption at the option of the Company, at any time on or after March 15, 2010, in whole or
from time to time in part in increments of $1,000 or an integral multiple of $1,000 (provided that any remaining principal amount hereof shall be an authorized denomination), at a Redemption Price equal to 100% of the principal amount, plus accrued
and unpaid Interest, including Contingent Interest, to, but excluding, the Redemption Date. However, payments due with respect to this Debenture on or prior to the Redemption Date will be payable to the Holder of this Debenture of record at the
close of business on the relevant Regular Record Date specified on the face hereof, all as provided in the



8



---

Indenture. The Company may exercise such option by causing the Trustee to mail a notice of such redemption, at least 20
but not more than 60 calendar days prior to the date of redemption, in accordance with the provisions of the Indenture. In the event of redemption of this Debenture in part only, this Debenture will be cancelled and new Debentures representing the
unredeemed portion hereof will be issued in the name of the Holder hereof.



Section 4. Conversion



Subject to and in compliance with the provisions of the Indenture, a Holder is entitled, at such Holders option, to convert the Holders Debentures (or any portion of the principal amount thereof that is $1,000 or an integral
multiple $1,000), into fully paid and nonassessable shares of Common Stock of Fisher (or, at the election of the Company as provided in the Indenture, cash or a combination of Common Stock of Fisher and cash) at the Conversion Price in effect at the
time of conversion, under certain circumstances set forth in the Indenture.



A Debenture in respect of which a Holder has delivered a Repurchase Notice exercising the option of such Holder to require the Company to repurchase such Debenture may be converted only if such notice of exercise is
withdrawn in accordance with the terms of the Indenture.



The
initial Conversion Price is $59.09 per share of Common Stock of Fisher (a Conversion Rate of approximately 16.9233 shares of Common Stock per $1,000 principal amount of Debentures), subject to adjustment in certain events described in the Indenture.
A Holder that surrenders Debentures for conversion will receive cash or a check in lieu of any fractional share of Common Stock. The Company from time to time may voluntarily reduce the Conversion Price.



To surrender a Debenture for conversion, a Holder must (1) complete and
manually sign the conversion notice below (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent, (2) surrender the Debenture to the Conversion Agent, (3) furnish appropriate endorsements and
transfer documents and (4) pay any transfer or similar tax, if required.



No fractional shares of Common Stock shall be issued upon conversion of any Debenture. Instead of any fractional share of Common Stock that would otherwise be issued upon conversion of such Debenture, the Company
shall pay a cash adjustment as provided in the Indenture.



No
payment or adjustment will be made for dividends on the shares of Common Stock, except as provided in the Indenture.



If Fisher (i) is a party to a consolidation, merger or binding share exchange (ii) reclassifies the Common Stock or (iii) conveys, transfers or leases its
properties and assets substantially as an entirety to any Person, the right to convert a Debenture into shares of Common Stock may be changed into a right to convert it into securities, cash or other assets of Fisher or such other Person.

Interest (including Contingent Interest) to, but excluding, the Repurchase Date. In addition, subject to the terms and conditions of the Indenture and at the option of the Holder, following the occurrence of a Change of Control, the Company shall
become obligated to purchase all of such Holders Debentures, or any portion of the principal amount thereof that is equal to any integral multiple of $1,000, on the date that is 30 days after the date of the Company Notice given in connection
with such Change of Control at a Repurchase Price equal to 100% of the principal amount of the Debentures to be repurchased, plus accrued and unpaid Interest (including Contingent Interest) to, but excluding, the Change of Control Repurchase Date.

Depositary, as applicable, with respect to which the repurchase right is being exercised, with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer, in form satisfactory to the Company and the Trustee
duly executed by, the Holder thereof or such Holders attorney duly authorized in writing.

provisions of the Indenture.



10



---

If cash sufficient to pay the Repurchase Price of all Debentures or portions thereof to be purchased as
of the Repurchase Date is deposited with the Paying Agent on the Business Day following the applicable Repurchase Date, Interest (including Contingent Interest) ceases to accrue on such Debentures (or portions thereof) immediately after such
applicable Repurchase Date, and the Holder thereof shall have no other rights as such other than the right to receive the Repurchase Price upon surrender of such Debentures.



Section 6. Tax Treatment. The Company agrees, and by acceptance of a beneficial ownership interest in the Debentures
each beneficial holder of Debentures will be deemed to have agreed unless otherwise required by the Internal Revenue Service, for United States federal income tax purposes (1) to treat the Debentures as indebtedness that is subject to Treas. Reg.
Sec. 1.1275-4 (the Contingent Payment Regulations) and, for purposes of the Contingent Payment Regulations, to treat the fair market value of any stock beneficially received by a beneficial holder upon any conversion of the Debentures as
a contingent payment and (2) to be bound by the Companys determination of the comparable yield and projected payment schedule, within the meaning of the Contingent Payment Regulations, with respect to the Debentures. A
Holder of Debentures may obtain the amount of original issue discount, issue date, yield to maturity, comparable yield and projected payment schedule by submitting a written request for it to the Company at the following address: Apogent
Technologies Inc., c/o Fisher Scientific International Inc., One Liberty Lane, Hampton, New Hampshire 03842, Attention: General Counsel.



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

to a sinking fund.



Section 8. Events of Default. If any
Event of Default with respect to Debentures shall occur and be continuing, the principal of all the Debentures may be declared due and payable in the manner and with the effect provided in the Indenture.



Section 9. Modification or Waiver; Obligation of the Company Absolute.
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Debentures at any time by the Company and the Trustee
with the consent of the Holders of not less than a majority in principal amount of the Outstanding Debentures. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Outstanding Debentures,
on



11



---

behalf of the Holders of all Debentures, to waive, with respect to the Debentures, compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Debenture will be conclusive and binding upon such Holder and upon all future Holders of this
Debenture and of any Debenture issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Debenture.



No reference herein to the Indenture and no provision of this Debenture or of
the Indenture will alter or impair the obligations of the Company, which are absolute and unconditional, to pay the principal of, and Interest (including Contingent Interest) on this Debenture at the times, places and rates herein prescribed and to
convert this Debenture in accordance with the Indenture.



Section 10. Satisfaction and Discharge. Provisions contained in the Indenture provide that the Company may satisfy and discharge its obligations under the Indenture while Debentures remain outstanding, subject to certain conditions,
if all outstanding Debentures have become due and payable at their scheduled maturity or all outstanding Debentures have been redeemed.



Section 11. Authorized Denominations. The Debentures are issuable only in global or certificated registered form, without coupons, in denominations
of $1,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein specified and to the limitations described below, if applicable, the Debentures are exchangeable for a like
aggregate principal amount of Debentures with a like Stated Maturity and with like terms and conditions of a different authorized denomination, as requested by the Holder surrendering the same.



Section 12. Registration of Transfer. As provided in the Indenture and
subject to certain limitations therein specified and to the limitations described below, if applicable, the transfer of this Debenture is registerable in the Register upon surrender of this Debenture for registration of transfer at the office or
agency of the Company maintained for that purpose duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar (which will initially be the Trustee at its principal corporate trust office
located in the Borough of Manhattan, The City of New York), duly executed by the Holder hereof or its attorney duly authorized in writing, and thereupon one or more new Debentures of authorized denominations and for the same Stated Maturity and
aggregate principal amount will be issued to the designated transferee or transferees.



This Debenture is exchangeable for certificated Debentures only upon the terms and conditions provided in the Indenture. Except as provided in the Indenture, owners of beneficial interests in a Global Security will
not be entitled to receive physical delivery of Debentures in certificated registered form and will not be considered the Holders thereof for any purpose under the Indenture.
