(d) The 2015 Notes shall bear interest at the rate of 6% per annum, and the 2019 Notes shall bear interest at the rate of 7% per annum, in each case from May 21, 2009 or from the most recent date to which interest has been paid or duly provided for, as further provided in the forms of Note annexed hereto as Exhibit A-1 and Exhibit A-2, respectively.

The Notes shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its Chief Executive Officer, its President, its Chief Financial Officer or one of its Vice Presidents, and attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Notes may be manual or facsimile.

Notes bearing the manual or facsimile signatures of individuals who were at any time 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 Notes or did not hold such offices at the date of such Notes.

On Company Order, the Trustee shall authenticate for original issue Notes in an aggregate principal amount specified in the Company Order. The Trustee shall be entitled to receive an Officer’s Certificate and an Opinion of Counsel of the Company that it may reasonably request in connection with such authentication of Notes. Such Company Order shall specify the amount of Notes to be authenticated and the date on which the original issue of Notes is to be authenticated.

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

Section 3.04. Book-entry Provisions for Global Securities. (a) Each Global Security initially shall (i) be registered in the name of the Depositary for such Global Securities or the nominee of such Depositary, (ii) be delivered to the Trustee as custodian for such Depositary and (iii) bear legends as set forth in Section 204 of the Base Indenture.

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any 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.

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 Global Securities.

(b) Transfers of a Global Security shall be limited to transfers of such Global Security in whole, but not in part, to the Depositary, its successors or their respective Nominees. Interests of beneficial owners in a Global Security may be

transferred or exchanged for physical Notes in accordance with the applicable rules and procedures of the Depositary and the provisions of Sections 305 of the Base Indenture.

(c) In connection with any transfer or exchange of a portion of the beneficial interest in any Global Security to beneficial owners for physical Notes pursuant to paragraph (b), the Security Registrar shall record on its books and records the date and a decrease in the principal amount of such Global Security in an amount equal to the beneficial interest in the Global Security being transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more physical Notes of like tenor and principal amount of authorized denominations.

(e) Any beneficial interest in one of the Global Securities that is transferred to a Person who takes delivery in the form of an interest in the other Global Security will, upon transfer, cease to be an interest in such Global Security and become an interest in the other Global Security and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Security for as long as it remains such an interest.

Section 3.05. Additional Notes. The Company may, from time to time, subject to compliance with any other applicable provisions of this Indenture, without the consent of the Holders of the Notes, create and issue pursuant to this Indenture additional Notes (“Additional Notes”) having terms and conditions set forth in Exhibit A-1 or Exhibit A-2, as applicable, identical to those of the other Notes of such series, except that Additional Notes of a series:

No Additional Notes of a series shall be issued, however, unless such Additional Notes will be fungible for U.S. federal income tax purposes with Notes of such series issued on the date hereof.

(c) On and after the Redemption Date for a series of Notes, interest will cease to accrue on such Notes or any portion thereof called for redemption, unless the Company defaults in the payment of the Redemption Price and accrued interest, if any. On or before the Redemption Date for the Notes, the Company shall deposit with the Trustee or a Paying Agent, funds sufficient to pay the Redemption Price of the Notes to be redeemed on the Redemption Date, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest, if any. If less than all of the Notes of a series are to be redeemed, the Depositary shall select the Notes to be redeemed in accordance with its operational arrangements. If the Notes are not Global Notes held by the Depositary, the Notes to be redeemed shall be selected by the Trustee by such method as the Trustee deems fair and appropriate; provided, however that in no event, shall Notes of a principal amount of $2,000 or less be redeemed in part.

(d) Notice of any redemption shall be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed; provided, however, that if the Trustee is asked to give such notice it shall be notified in writing of such request at least 15 days prior to the date of the giving of such notice (unless a shorter notice shall be satisfactory to the Trustee). Such notice shall state the Redemption Price (if known) or the formula pursuant to which the Redemption Price is to be determined if the Redemption Price cannot be determined at the time the notice is given. If the Redemption Price cannot be determined at the time such notice is to be given, the actual Redemption Price, calculated as described above in clause (b), shall be set forth in an Officer’s Certificate of the Company delivered to the Trustee no later than two Business Days prior to the Redemption Date. Notice of redemption having been given as provided in the Indenture, the Notes called for redemption shall become due and payable on the Redemption Date and at the applicable Redemption Price, plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

Section 4.02. Special Mandatory Redemption. If, for any reason, (i) the Company’s proposed acquisition of the diagnostic systems portion of Olympus Corporation’s life sciences business is not consummated on or prior to January 30, 2010 or (ii) the Master Purchase Agreement is terminated on or prior to January 30, 2010, the Company shall redeem all of the Outstanding Notes on the Special Mandatory Redemption Date at the Special Mandatory Redemption Price. Notice of a special mandatory redemption will be mailed promptly after the occurrence of the event triggering such redemption to the registered address of each Holder of Notes. If funds sufficient to pay the Special Mandatory Redemption Price of all of the Notes to be redeemed on the Special Mandatory Redemption Date are deposited with a Paying Agent or the Trustee on or before such Special Mandatory Redemption Date, on and after such Special Mandatory Redemption Date, the Notes will cease to bear interest and, other than the right to receive the Special Mandatory Redemption Price, all rights under the Notes shall terminate.

Section 4.03. Repurchase of Notes Upon a Change of Control. (a) If a Change of Control Triggering Event occurs with respect to a series of Notes, unless (i) the Company shall have exercised its option to redeem such Notes as described in Section 4.01 of this Supplemental Indenture or (ii) the Company shall have mailed notice of a special mandatory redemption pursuant to Section 4.02 hereof, the Company shall be required to make an offer (the “Change of Control Offer”) to each Holder of such Notes to repurchase all or any part (equal to $2,000 or any multiple of $1,000 in excess thereof) of that ▇▇▇▇▇▇’s Notes of such series on the terms set forth in this Section 4.03 and in the Notes. In the Change of Control Offer, the Company shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased up to, but not including, the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event with respect to a

series of Notes or, at the option of the Company, prior to any Change of Control, but after the public announcement of the transaction that constitutes or may constitute the Change of Control, the Company shall mail a notice to Holders of Notes describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed or, if the notice is mailed prior to the Change of Control, no earlier than 30 days and no later than 60 days from the date on which the Change of Control Triggering Event occurs (the “Change of Control Payment Date”). The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. On the Change of Control Payment Date, the Company shall, to the extent lawful:

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

(ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased.

The Company shall publicly announce the results of the Change of Control Offer on or as soon as possible after the date of purchase.

(c) The Company shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party purchases all Notes properly tendered and not withdrawn under its offer. In addition, the Company shall not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than an Event of Default arising as a result of a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

(d) The Company shall comply in all material respects with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the

Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

6% Senior Notes due 2015

1. Interest.

▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, Inc. (the “Issuer”) promises to pay interest on the principal amount of this Note at the rate per annum described above. Cash interest on the Notes will accrue from the most recent date to which interest has been paid; or, if no interest has been paid, from May 21, 2009. Interest on this Note will be paid to but excluding the relevant Interest Payment Date or on such earlier date as the principal amount shall become due in accordance with the provisions hereof. The Issuer will pay interest semi-annually in arrears on each Interest Payment Date, commencing December 1, 2009. If any Interest Payment Date or the Stated Maturity of the Notes is not a Business Day, then the related payment of interest or principal payable, as applicable, on such date will be paid on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date or Stated Maturity and no further interest will accrue as a result of such delay. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.

The Issuer shall pay interest on overdue principal from time to time on demand at the rate borne by the Notes and on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful.

2. Paying Agent.

Initially, ▇▇▇▇▇ Fargo Bank, N.A. (the “Trustee”) will act as paying agent. The Issuer may change any paying agent without notice to the Holders.

3. Indenture; Defined Terms.

This Note is one of the 6% Senior Notes due 2015 (the “Notes”) issued under the Senior Indenture dated as of April 25, 2001 (as amended, modified or supplemented from time to time in accordance therewith, the “Base Indenture” and, as amended, modified and supplemented by the Third Supplemental Indenture dated as of May 21, 2009, the “Indenture”) by and between the Issuer and the Trustee, as successor trustee. This Note is a “Security” and the Notes are “Securities” under the Indenture.

For purposes of this Note, unless otherwise defined herein, capitalized terms herein are used as defined in the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to

the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “TIA”) as in effect on the date on which the Indenture was qualified under the TIA. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and holders of Notes are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Note are inconsistent, the terms of the Indenture shall govern.

The Notes are in registered form, without coupons, in denominations of $2,000 and multiples of $1,000 thereafter.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Holders of the Securities of all series affected under the Indenture at any time by the Issuer and the Trustee with the consent of the Holders of a majority in principal amount of the Securities of all series at the time Outstanding affected thereby (voting as one class). The Indenture contains provisions permitting the Holders of not less than a majority in principal amount of the Securities of all series at the time Outstanding with respect to which a default under the Indenture shall have occurred and be continuing (voting as one class), on behalf of the Holders of the Securities of all such series, to waive, with certain exceptions, such past default with respect to all such series and its consequences. The Indenture also permits the Holders of not less than a majority in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Issuer with certain provisions of the Indenture. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

6. Optional Redemption.

The Issuer may redeem the Notes in whole or in part, at its option, at any time or from time to time prior to maturity on at least 30 days, but not more than 60 days, prior notice mailed to the registered address of each Holder of the Notes (the “Redemption Date”). The redemption price will be equal to the greater of:

(i) 100% of the principal amount of the Notes to be redeemed; or

(ii) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of interest and principal thereon (exclusive of interest accrued and unpaid to, but not including, the Redemption Date) discounted to the Redemption Date, on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months), at a rate equal to the sum of the Treasury Rate plus 50 basis points,

plus, in either case, accrued interest thereon to, but not including, the Redemption Date.

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on interest payment dates falling on or prior to a Redemption Date will be payable on the interest payment date to the registered Holders as of the close of business on the relevant record date according to the Notes and the Indenture.

On and after the Redemption Date for the Notes, interest will cease to accrue on the Notes or any portion thereof called for redemption, unless the Issuer defaults in the payment of the Redemption Price and accrued interest, if any. On or before the Redemption Date for the Notes, the Issuer shall deposit with the Trustee or a Paying Agent, funds sufficient to pay the Redemption Price of the Notes to be redeemed on the Redemption Date, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest, if any. If less than all of the Notes are to be redeemed, the Depositary shall select the Notes to be redeemed in accordance with its operational arrangements. If the Notes are not Global Notes held by the Depositary, the Notes to be redeemed shall be selected by the Trustee by such method as the Trustee deems fair and appropriate; provided, however that in no event, shall Notes of a principal amount of $2,000 or less be redeemed in part.

Notice of any redemption shall be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed; provided, however, that if the Trustee is asked to give such notice it shall be notified in writing of such request at least 15 days prior to the date of the giving of such notice (unless a shorter notice shall be satisfactory to the Trustee). Such notice shall state the Redemption Price (if known) or the formula pursuant

to which the Redemption Price is to be determined if the Redemption Price cannot be determined at the time the notice is given. If the Redemption Price cannot be determined at the time such notice is to be given, the actual Redemption Price, calculated as described above, shall be set forth in an Officer’s Certificate of the Issuer delivered to the Trustee no later than two Business Days prior to the Redemption Date. Notice of redemption having been given as provided in the Indenture, the Notes called for redemption shall become due and payable on the Redemption Date and at the applicable Redemption Price, plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

7. Special Mandatory Redemption

If, for any reason, (i) the Issuer’s proposed acquisition of the diagnostic systems portion of Olympus Corporation’s life sciences business is not consummated on or prior to January 30, 2010 or (ii) the master purchase agreement dated as of February 27, 2009, between Olympus Corporation, as the seller, and the Issuer, as the purchaser, as amended from time to time (the “Master Purchase Agreement”), is terminated on or prior to January 30, 2010, the Issuer shall redeem all of the Notes on the earlier to occur of (1) January 30, 2010 if the proposed acquisition of the diagnostic systems portion of Olympus Corporation’s life sciences business has not been completed on or prior to January 30, 2010 or (2) the 30th day (or if such day is not a Business Day, the first Business Day thereafter) following the termination of the Master Purchase Agreement (the “Special Mandatory Redemption Date”) at 101% of the aggregate principal amount of the Outstanding Notes together with accrued and unpaid interest, if any, from May 21, 2009 to, but not including, the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”). Notice of a special mandatory redemption will be mailed promptly after the occurrence of the event triggering such redemption to the registered address of each Holder of Notes. If funds sufficient to pay the Special Mandatory Redemption Price of all of the Notes to be redeemed on the Special Mandatory Redemption Date are deposited with a Paying Agent or the Trustee on or before such Special Mandatory Redemption Date, on and after such Special Mandatory Redemption Date, the Notes will cease to bear interest and, other than the right to receive the Special Mandatory Redemption Price, all rights under the Notes shall terminate.

8. Offer to Repurchase Upon Change of Control

Upon the occurrence of a Change of Control Triggering Event with respect to the Notes, unless the Issuer shall have exercised its right pursuant to Section 6 hereof to redeem the Notes or shall have mailed notice of a special mandatory redemption of the Notes pursuant to Section 7 hereof, the Issuer shall be required to make an offer (the “Change of Control Offer”) to each Holder of such Notes to repurchase all or any part (equal to $2,000 or any multiple of

$1,000 in excess thereof) of that ▇▇▇▇▇▇’s Notes on the terms set forth in the Supplemental Indenture and in the Notes. In the Change of Control Offer, the Issuer shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased up to, but not including, the date of repurchase (the “Change of Control Payment”).

Within 30 days following any Change of Control Triggering Event with respect to the Notes or, at the option of the Issuer, prior to any Change of Control, but after the public announcement of the transaction that constitutes or may constitute the Change of Control, the Issuer shall mail a notice to Holders of Notes describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed or, if the notice is mailed prior to the Change of Control, no earlier than 30 days and no later than 60 days from the date on which the Change of Control Triggering Event occurs (the “Change of Control Payment Date”). The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

On the Change of Control Payment Date, the Issuer shall, to the extent lawful:

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

(ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

The Issuer shall publicly announce the results of the Change of Control Offer on or as soon as possible after the date of purchase.

The Issuer shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer and the third party purchases all Notes properly tendered and not withdrawn under its offer. In addition, the Issuer shall not repurchase any Notes if there has occurred and is continuing on the

Change of Control Payment Date an Event of Default under the Indenture, other than an Event of Default arising as a result of a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

The Issuer shall comply in all material respects with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

9. Defaults and Remedies.

If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities may declare the principal amount of all the Securities of that series to be due and payable immediately, by a notice in writing to the Issuer (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable.

The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Outstanding Securities of any series 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, with respect to the Securities of such series.

If an Event of Default is continuing with respect to all Outstanding Securities, the Holders of a majority in principal amount of all the Outstanding Securities, considered as one class, shall have the right to make such direction, and not the Holders of Securities of any one series.

10. Authentication.

This Note shall not be valid until the Trustee manually signs the certificate of authentication on this Note.

11. Abbreviations and Defined Terms.

Customary abbreviations may be used in the name of a Holder of a Note or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

12. CUSIP Numbers.

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the accuracy of such numbers as printed on the Notes and reliance may be placed only on the other identification numbers printed hereon.

13. Governing Law.

The laws of the State of New York shall govern the Indenture and this Note thereof.
