(a) Interest payable on any Interest Payment Date or at Maturity with respect to a series of Notes shall be the amount of interest accrued from, and including, the immediately preceding Interest Payment Date in respect of which interest has been paid or duly provided for (or from and including the original issue date of August 23, 2011, if no interest has

been paid or duly provided for with respect to the series of Notes) to, but excluding, such Interest Payment Date or Maturity Date, as the case may be (each, an “Interest Period”).

(b)                                 Interest on the Floating Rate Notes will be payable quarterly on February 15, May 15, August 15 and November 15 of each year (each a “Floating Rate Note Interest Payment Date”), commencing November 15, 2011, to the Persons in whose name such Floating Rate Notes are registered at the close of business on February 1, May 1, August 1 or November 1, as applicable, immediately before the applicable Floating Rate Note Interest Payment Date, except as provided in Section 3.05(f) hereof. Interest on the Floating Rate Notes will be computed on the basis of the actual number of days elapsed over a 360-day year. If any Floating Rate Note Interest Payment Date (other than the Maturity Date of the Floating Rate Notes) is not a Floating Rate Business Day, the Company will pay interest on the next day that is a Floating Rate Business Day as if payment were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the immediately succeeding Floating Rate Business Day, except that if such Floating Rate Business Day is in the immediately succeeding calendar month, such Floating Rate Note Interest Payment Date (other than the Maturity Date of the Floating Rate Notes) shall be the immediately preceding Floating Rate Business Day. If the Maturity Date of the Floating Rate Notes is not a Floating Rate Business Day, the Company will pay interest, if any, and principal and premium, if any, on the next day that is a Floating Rate Business Day as if payment were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the immediately succeeding Floating Rate Business Day.

(i)                                     The interest rate on the Floating Rate Notes shall be reset quarterly on February 15, May 15, August 15 and November 15 of each year, as applicable, commencing November 15, 2011 (each, an “Interest Reset Date”). The Floating Rate Notes will bear interest at a per annum rate equal to three-month LIBOR (as defined below) for the applicable Interest Reset Period or Initial Interest Period (each as defined below) plus 1.50%. The interest rate for the Initial Interest Period will be three-month LIBOR, determined as of two London business days prior to the original issue date, plus 1.50%. The “Initial Interest Period” will be the period from and including the original issue date to but excluding the initial Interest Reset Date. Thereafter, each “Interest Reset Period” will be the period from and including an Interest Reset Date to but excluding the immediately succeeding Interest Reset Date; provided that the final Interest Reset Period for the Floating Rate Notes will be the period from and including the Interest Reset Date immediately preceding the Maturity Date of such Floating Rate Notes to but excluding the Maturity Date for the Floating Rate Notes.

If any Interest Reset Date would otherwise be a day that is not a Floating Rate Business Day, the Interest Reset Date will be postponed to the immediately succeeding day that is a Floating Rate Business Day, except that if that Floating Rate Business Day is in the immediately succeeding calendar month, the Interest Reset Date shall be the immediately preceding Floating Rate Business Day.

The interest rate in effect on each day will be (i) if that day is an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as defined below) immediately preceding such Interest Reset Date or (ii) if that day is not an Interest Reset Date, the interest rate determined as of the Interest Determination Date immediately preceding the most recent Interest Reset Date or the original issue date, as the case may be.

(ii)                                  The interest rate applicable to each Interest Reset Period commencing on the related Interest Reset Date, or the original issue date in the case of the Initial Interest Period, will be the rate determined as of the applicable Interest Determination Date. The “Interest Determination Date” will be the second Floating Rate Business Day immediately preceding the original issue date, in the case of the Initial Interest Period, or thereafter the second Floating Rate Business Day immediately preceding the applicable Interest Reset Date.

(iii)                               Three-month LIBOR will be determined by the Calculation Agent as of the applicable Interest Determination Date in accordance with the following provisions:

(A) LIBOR is the rate for deposits in U.S. dollars for the three-month period which appears on Reuters Screen LIBOR01 Page (as defined below) at approximately 11:00 a.m., London time, on the applicable Interest Determination Date. “Reuters Screen LIBOR01 Page” means the display designated on page “LIBOR01” on Reuters Screen (or such other page as may replace the LIBOR01 page on that service, any successor service or such other service or services as may be nominated by the British Bankers’ Association for the purpose of displaying London interbank offered rates for U.S. dollar deposits). If no rate appears on Reuters Screen LIBOR01 Page, LIBOR for such Interest Determination Date will be determined in accordance with the provisions of Section 3.05(b)(iii)(B) hereof; and

(B) With respect to an Interest Determination Date on which no rate appears on Reuters Screen LIBOR01 Page as of approximately 11:00 a.m., London time, on such Interest Determination Date, the Calculation Agent shall request the principal London offices of each of four major reference banks in the London interbank market selected by the Calculation Agent (after consultation with the Company) to provide the Calculation Agent with a quotation of the rate at which deposits of U.S. dollars having a three-month maturity, commencing on the second London business day immediately following such Interest Determination Date, are offered by it to prime banks in the London interbank market as of approximately 11:00 a.m., London time, on such Interest Determination Date in a principal amount equal to an amount of not less than U.S. $1,000,000 that is representative for a single transaction in such market at such time. If at least two such quotations are provided, LIBOR for such Interest Determination Date will be the arithmetic mean of such quotations as calculated by the Calculation Agent. If fewer than two quotations are provided, LIBOR for such Interest Determination Date will be the arithmetic mean of the rates quoted as of approximately 11:00 a.m., New York City time, on such Interest Determination Date by three major banks selected by the Calculation Agent (after consultation with the Company) for loans in U.S. dollars to leading European banks having a three-month maturity commencing on the second London business day immediately following such Interest Determination Date and in a principal amount equal to an amount of not less than U.S. $1,000,000 that is representative for a single transaction in such market at such time; provided, however, that if the banks selected as aforesaid by the Calculation Agent are not quoting such rates as mentioned in this sentence, LIBOR for such Interest Determination Date will be LIBOR determined with respect to the immediately preceding Interest Determination Date.

All percentages resulting from any calculation of any interest rate for the Floating Rate Notes will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or 0.09876545) would be rounded to 9.87655% (or 0.0987655)), and all dollar amounts will be rounded to the nearest cent, with one-half cent being rounded upward.

Promptly upon such determination, the Calculation Agent shall notify the Company and the Trustee (if the Calculation Agent is not the Trustee) of the interest rate for the new Interest Reset Period. Upon request of a Holder of the Floating Rate Notes, the Calculation Agent will provide to such Holder the interest rate in effect on the date of such request and, if determined, the interest rate for the next Interest Reset Period. All calculations made by the Calculation Agent for the purposes of calculating interest on the Floating Rate Notes shall be conclusive and binding on the Holders and the Company, absent manifest errors.

(c)                                  The 2016 Notes will bear interest at the rate of 2.750% per year from the original issue date thereof through and including the Maturity Date of the 2016 Notes.

offer. 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 a Default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

DENTSPLY INTERNATIONAL INC.

Floating Rate Note due 2013

CUSIP: 249030 AA5

DENTSPLY International Inc., a corporation organized and existing under the laws of Delaware (hereinafter called the “Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to            , or registered assigns, [the principal sum of $[    ]](1) on August 15, 2013, and to pay interest thereon from August 23, 2011 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, quarterly in arrears on February 15, May 15, August 15 and November 15 of each year, commencing November 15, 2011 (each, an “Interest Payment Date”), to the Persons in whose name this Note is registered at the close of business on the

(1)  USE FOLLOWING LANGUAGE INSTEAD for GLOBAL NOTES: [the principal sum as set forth in the Schedule of Increases or Decreases In Note attached hereto]

Record Date for such Interest Payment Date, as applicable, immediately before the applicable Interest Payment Date. Interest on the Notes of this series will be computed on the basis of the actual number of days elapsed over a 360-day year.

If any Interest Payment Date (other than the Maturity Date of the Notes of this series) is not a Floating Rate Business Day, the Company will pay interest on the next day that is a Floating Rate Business Day as if payment were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the immediately succeeding Floating Rate Business Day, except that if such Floating Rate Business Day is in the immediately succeeding calendar month, such Interest Payment Date (other than the Maturity Date of the Notes of this series) shall be the immediately preceding Floating Rate Business Day. If the Maturity Date of the Notes of this series is not a Floating Rate Business Day, the Company will pay interest, if any, and principal and premium, if any, on the next day that is a Floating Rate Business Day as if payment were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the immediately succeeding Floating Rate Business Day.

The interest rate on the Notes of this series shall be reset quarterly on February 15, May 15, August 15 and November 15 of each year, as applicable, commencing November 15, 2011 (each, an “Interest Reset Date”). The Notes of this series will bear interest at a per annum rate equal to three-month LIBOR (as defined below) for the applicable Interest Reset Period or Initial Interest Period (each as defined below) plus 1.50%. The interest rate for the Initial Interest Period will be three-month LIBOR, determined as of two London business days prior to the original issue date, plus 1.50%. The “Initial Interest Period” will be the period from and including the original issue date to but excluding the initial Interest Reset Date. Thereafter, each “Interest Reset Period” will be the period from and including an Interest Reset Date to but excluding the immediately succeeding Interest Reset Date; provided that the final Interest Reset Period for the Notes of this series will be the period from and including the Interest Reset Date immediately preceding the Maturity Date of such Notes to but excluding the Maturity Date for such Notes.

If any Interest Reset Date would otherwise be a day that is not a Floating Rate Business Day, the Interest Reset Date will be postponed to the immediately succeeding day that is a Floating Rate Business Day, except that if that Floating Rate Business Day is in the immediately succeeding calendar month, the Interest Reset Date shall be the immediately preceding Floating Rate Business Day.

The interest rate in effect on each day will be (i) if that day is an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as defined below) immediately preceding such Interest Reset Date or (ii) if that day is not an Interest Reset Date, the interest rate determined as of the Interest Determination Date immediately preceding the most recent Interest Reset Date or the original issue date, as the case may be.

The interest rate applicable to each Interest Reset Period commencing on the related Interest Reset Date, or the original issue date in the case of the Initial Interest Period, will be the rate determined as of the applicable Interest Determination Date. The “Interest Determination Date” will be the second Floating Rate Business Day immediately preceding the original issue date, in the case of the Initial Interest Period, or thereafter the second Floating Rate Business Day immediately preceding the applicable Interest Reset Date.

Three-month LIBOR will be determined by the Calculation Agent as of the applicable Interest Determination Date in accordance with the following provisions:

(A) LIBOR is the rate for deposits in U.S. dollars for the three-month period which appears on Reuters Screen LIBOR01 Page (as defined below) at approximately 11:00 a.m., London time, on the applicable Interest Determination Date. “Reuters Screen LIBOR01 Page” means the display designated on page “LIBOR01” on Reuters Screen (or such other page as may replace the LIBOR01 page on that service, any successor service or such other service or services as may be nominated by the British Bankers’ Association for the purpose of displaying London interbank offered rates for U.S. dollar deposits). If no rate appears on Reuters Screen LIBOR01 Page, LIBOR for such Interest Determination Date will be determined in accordance with the provisions of clause (B) below; and

(B) With respect to an Interest Determination Date on which no rate appears on Reuters Screen LIBOR01 Page as of approximately 11:00 a.m., London time, on such Interest Determination Date, the Calculation Agent shall request the principal London offices of each of four major reference banks in the London interbank market selected by the Calculation Agent (after consultation with the Company) to provide the Calculation Agent with a quotation of the rate at which deposits of U.S. dollars having a three-month maturity, commencing on the second London business day immediately following such Interest Determination Date, are offered by it to prime banks in the London interbank market as of approximately 11:00 a.m., London time, on such Interest Determination Date in a principal amount equal to an amount of not less than U.S. $1,000,000 that is representative for a single transaction in such market at such time. If at least two such quotations are provided, LIBOR for such Interest Determination Date will be the arithmetic mean of such quotations as calculated by the Calculation Agent. If fewer than two quotations are provided, LIBOR for such Interest Determination Date will be the arithmetic mean of the rates quoted as of approximately 11:00 a.m., New York City time, on such Interest Determination Date by three major banks selected by the Calculation Agent (after consultation with the Company) for loans in U.S. dollars to leading European banks having a three-month maturity commencing on the second London business day immediately following such Interest Determination Date and in a principal amount equal to an amount of not less than U.S. $1,000,000 that is representative for a single transaction in such market at such time; provided, however, that if the banks selected as aforesaid by the Calculation Agent are not quoting such rates as mentioned in this sentence, LIBOR for such Interest Determination Date will be LIBOR determined with respect to the immediately preceding Interest Determination Date.

All percentages resulting from any calculation of any interest rate for the Notes of this series will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or 0.09876545) would be rounded to 9.87655% (or 0.0987655)), and all dollar amounts will be rounded to the nearest cent, with one-half cent being rounded upward.

Promptly upon such determination, the Calculation Agent shall notify the Company and the Trustee (if the Calculation Agent is not the Trustee) of the interest rate for the

new Interest Reset Period. Upon request of a Holder, the Calculation Agent will provide to such Holder the interest rate in effect on the date of such request and, if determined, the interest rate for the next Interest Reset Period. All calculations made by the Calculation Agent for the purposes of calculating interest on the Notes of this series shall be conclusive and binding on the Holders and the Company, absent manifest errors.

Principal of, premium if any, and interest on this Note will be payable, the transfer of such Note will be registrable, and such Note will be exchangeable for Notes of this series of a like aggregate principal amount bearing identical terms and provisions, at the office or agency of the Company maintained for such purpose in the Borough of Manhattan, The City of New York, which shall initially be the Corporate Trust Office; provided, however, that payment of interest may be made at the option of the Company by check mailed to the Person entitled thereto at such address as shall appear in the Register or, in accordance with arrangements satisfactory to the Trustee, by wire transfer to an account designated by the Holder.

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed.

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents as we have deemed necessary or appropriate as a basis for the opinions stated below.

In our examination, we have assumed the genuineness of all signatures including endorsements, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified or photostatic copies, and the authenticity of the originals of such copies.  As to any facts relevant to the opinions stated herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and others and of public officials.

We do not express any opinion with respect to the laws of any jurisdiction other than (i) the General Corporation Law of the State of Delaware (the “DGCL”) and (ii) the laws of the State of New York, and to the extent that judicial or regulatory orders or decrees or consents, approvals, licenses, authorizations, validations, filings, recordings or registrations with governmental authorities are relevant, to those required under such laws (all of the foregoing being referred to as “Opined on Law”).  We do not express any opinion as to the effect of any non-Opined on Law on the opinions stated herein.

The Indenture and the Note Certificates are referred to herein collectively as the “Transaction Agreements.”

Based upon the foregoing and subject to the limitations, qualifications, exceptions and assumptions stated herein, we are of the opinion that the Note Certificates have been duly authorized by all requisite corporate action on the part of the Company and duly executed by the Company under the DGCL, and

3

when duly authenticated by the Trustee and issued and delivered by the Company against payment therefor in accordance with the terms of the Underwriting Agreement and the Indenture, the Note Certificates will constitute valid and binding obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms under the laws of the State of New York.

The opinions stated herein are subject to the following qualifications:

1.             the opinions stated herein are limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer, preference and other similar laws affecting creditors’ rights generally, and by general principles of equity (regardless of whether enforcement is sought in equity or at law);

2.             except to the extent expressly stated in the opinions contained herein, we do not express any opinion with respect to the effect on the opinions stated herein of (i) the compliance or non-compliance of any party to any of the Transaction Agreements with any laws, rules or regulations applicable to such party or (ii) the legal status or legal capacity of any such party to any of the Transaction Agreements;

3.             except to the extent expressly stated in the opinions contained herein, we have assumed that each of the Transaction Agreements constitutes the valid and binding obligation of each party to such Transaction Agreement, enforceable against such party in accordance with its terms; and

4.             to the extent that any opinion relates to the enforceability of the choice of New York law and choice of New York forum provisions contained in any Transaction Agreement, the opinions stated herein are rendered solely in reliance upon New York General Obligations Law sections 5-1401 and 5-1402 and Rule 327(b) of New York Civil Practice Law and Rules and are subject to the qualification that such enforceability may be limited by, in each case, the terms of such sections 5-1401 and 5-1402, as well as by principles of public policy, comity or constitutionality.

In addition, in rendering the foregoing opinions we have assumed that neither the execution and delivery by the Company of the Transaction Agreements nor the consummation by the Company of the transactions contemplated thereby, including the issuance and sale of the Securities: (i) constitutes or will constitute a violation of, or a default under, any lease, indenture, instrument or other agreement to which the Company or its property is subject, (ii) contravenes or will contravene any order or decree of any governmental authority to which the Company or its property is subject, (iii) violates or will violate any law, rule or regulation to which the Company or its property is subject or (iv) requires the consent, approval,

4

licensing or authorization of, or any filing, recording or registration with, any governmental authority under any law, rule or regulation of any jurisdiction.

We hereby consent to the filing of this opinion with the Commission as an exhibit to the Company’s Current Report on Form 8-K being filed on the date hereof, and incorporated by reference into the Registration Statement.  We also hereby consent to the reference to our firm under the heading “Legal Matters” in the Preliminary Prospectus and the Prospectus.  In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the General Rules and Regulations.
