                                                 Borrower and the Banks
                                                 shall negotiate in
                                                 good faith to amend
                                                 this definition to

                                                 pending the
                                                 effectiveness of any

                                                 Percentage shall be

                                                 in effect prior to
                                                 such change or
                                                 cessation.  For
                                                 purposes of this
                                                 definition, a
                                                 reference to the
                                                 "lower" of two
                                                 Categories shall mean
                                                 the Category
                                                 designated by the
                                                 highest integer
                                                 (Category 5 being the
                                                 lowest Category).

             (h) Adding in the appropriate alphabetical order the
definition of "Utilization Fee" which shall read in its entirety as
follows:

                                       95

                   "Utilization Fee" shall have the meaning assigned to
       such term in Section 2.07(b).

             SECTION 7.  Article 2 of the Credit Agreement is hereby
amended as follows:

             (a) Section 2.07(c) shall become Section 2.07(d).

             (b) Section 2.07(b) shall become Section 2.07(c) and the
reference therein to "September 17, 1997" is deleted and substituted in
lieu thereof shall be a reference to "September 28, 1999".

             (c) A new Section 2.07(b) shall be inserted after Section
2.07(a) and shall read as follows:

                   (b)  The Borrower agrees to pay to each Bank,
       through the Administrative Agent, on each March 31, June 30,
       September 30 and December 31 and on the Maturity Date or any
       earlier date on which the Commitment of such Bank shall have
       terminated and the outstanding Loans of such Bank have been
       repaid in full, a utilization fee (a "Utilization Fee") at a
       rate per annum equal to (i) from the date hereof through the
       Termination Date, .100% on the aggregate amount of each Bank's
       outstanding Loans for each day on which the outstanding
       principal amount of Loans shall be greater than 33.33% of the
       total Commitments and (ii) thereafter, the Term-Out Applicable
       Percentage from time to time in effect (as determined in
       accordance with Section 2.09(e)) on the aggregate amount of each
       Bank's outstanding Loans.  All Utilization Fees shall be
       computed on the basis of a year of 360 days and shall be payable
       for the actual number of days elapsed (including the first day
       but excluding the last day).

             (d)  The text of Section 2.09(e) is deleted in its
entirety substituting in lieu thereof the following:

                   The Term-Out Applicable Percentage shall be
       determined based upon the ratings by S&P or Moody's, or both,
       applicable to the Index Debt.

            (e) The proviso at the end of the third sentence in
Section 2.12(d) stating "; provided, however, that no Bank may agree to
increase its Commitment hereunder unless it shall have agreed to
ratably increase its Commitment under the Facility B Credit Agreement
(if the Facility B Credit Agreement is then in effect)" is deleted in
its entirety.

             (f) A new Section 2.12(f) shall be inserted after Section
2.12(e) and shall read as follows:

                   (f) Notwithstanding the provisions of Section
       2.12(d), during the period of October 21, 1999 to December 21,
       1999, the Borrower may, by written

                                       96

       notice to the Administrative Agent, executed by the Borrower and one or
       more banks or other financial institution (any such bank or other
       financial institution referred to in this clause (e) being called a
       "Prospective Bank"), which may include any Bank, cause the Commitments of
       the Prospective Banks to be increased (or cause Commitments to be
       extended by the Prospective Banks, as the case may be) in an amount for
       each Prospective Bank set forth in such notice, provided, however, that
       (a) the Total Commitment after giving effect to such increase plus the
       aggregate amount of the commitments of the Banks to make loans under the
       Facility B Credit Agreement (after giving effect to any outstanding
       requests by the Borrower to increase such commitments) shall in no event
       exceed $350,000,000, (b) the Total Commitment shall in no event exceed
       $125,000,000, (c) each Prospective Bank, if not already a Bank hereunder,
       shall be subject to the approval of the Administrative Agent (which
       approval shall not be unreasonably withheld) and (d) each Prospective
       Bank, if not already a Bank hereunder, shall become a party to this
       Agreement on such date or dates as may be mutually satisfactory to such
       Prospective Bank, the Borrower and the Administrative Agent, subject to
       the Administrative Agent's receipt of a duly completed and executed
       Accession Agreement in the form of Exhibit F hereto. Increases and new
       Commitments created pursuant to this clause (e) shall become effective
       (A) in the case of Prospective Banks already parties hereunder, on the
       date specified in the notice delivered pursuant to this paragraph and (B)
       in the case of Prospective Banks not already parties hereunder, on the
       effective date of the Accession Agreement. Upon the effectiveness of any
       Accession Agreement to which any Prospective Bank is a party, (i) such
       Prospective Bank shall thereafter be deemed to be a party to this
       Agreement and shall be entitled to all rights, benefits and privileges
       accorded a Bank hereunder and subject to all obligations of a Bank
       hereunder and (ii) Schedule 2.01 shall be deemed to have been amended to
       reflect the Commitment of the additional Bank as provided in such
       Accession Agreement. Upon the effectiveness of any increase in the
       Commitment pursuant to this paragraph of a Bank already a party
       hereunder, Schedule 2.01 shall be deemed to have been amended to reflect
       the increased Commitment of such Bank. Notwithstanding the foregoing, no
       increase in the Total Commitment (or in the Commitment of any Bank) shall
       become effective under this paragraph unless, on the date of such
       increase, the conditions set forth in paragraphs (b) and (c) of Section
       4.01 shall be satisfied (with all references in such paragraphs to a
       Borrowing being deemed to be references to such increase) and the
       Administrative Agent shall have received a certificate to that effect
       dated such date and executed by a Financial Officer of the Borrower.
       Following any increase of a Bank's Commitment or any extension of a new
       Commitment pursuant to this paragraph, any Revolving Credit Loans
       outstanding prior to the effectiveness of such increase or extension
       shall continue outstanding until the ends of the respective interests
       periods applicable thereto, and shall then be repaid or refinanced with
       new Revolving Credit Loans made pursuant to Sections 2.01 and 2.05.

                                       97

             (f)  A new Section 2.23 (i) shall be inserted after
Section 2.23(h) and shall read as follows:

                   (i)  Notwithstanding anything to the contrary
       contained herein, any Bank (a "Granting Bank") may grant to a
       special purpose funding vehicle (an "SPC"), identified as such
       in writing from time to time by the Granting Bank to the
       Administrative Agent and the Borrower, the option to provide to
       the Borrower all or any part of any Loan that such Granting Bank
       would otherwise be obligated to make to the Borrower pursuant to
       this Agreement; provided that (i) nothing herein shall
       constitute a commitment by any SPC to make any Loan and (ii) if
       an SPC elects not to exercise such option or otherwise fails to
       provide all or any part of such Loan, the Granting Bank shall be
       obligated to make such Loan pursuant to the terms hereof.  The
       making of a Loan by an SPC hereunder shall utilize the
       Commitment of the Granting Bank to the same extent, and as if,
       such Loan were made by such Granting Bank.  Each party hereto
       hereby agrees that no SPC shall be liable for any indemnity or
       similar payment obligation under this Agreement (all liability
       for which shall remain with the Granting Bank).  In furtherance
       of the foregoing, each party hereto hereby agrees (which
       agreement shall survive the termination of this Agreement) that,
       prior to the date that is one year and one day after the payment
       in full of all outstanding commercial paper or other senior
       indebtedness of any SPC, it will not institute against, or join
       any other person in instituting against, such SPC any
       bankruptcy, reorganization, arrangement, insolvency or
       liquidation proceedings under the laws of the United States or
       any State thereof.  In addition, notwithstanding anything to the
       contrary contained in this paragraph, any SPC may (i) with
       notice to, but without the prior written consent of, the
       Borrower and the Administrative Agent and without paying any
       processing fee therefor, assign all or a portion of its
       interests in any Loans to the Granting Bank or to any financial
       institution providing liquidity and/or credit support to or for
       the account of such SPC to support the funding or maintenance of
       Loans and (ii) disclose on a confidential basis any non-public
       information relating to its Loans (A) to any rating agency,
       commercial paper dealer or provider of any surety undertaking,
       guarantee or credit or liquidity enhancement to such SPC that,
       in each case shall have been advised of the confidentiality of
       such information and the restrictions contained in Section 10.11
       on its disclosure to third parties, or (B) to other Persons as
       provided, and subject to the limitations set forth, in Section
       10.11.  The SPC shall be entitled to the benefits of Sections
       2.15 and 2.22 to the same extent, and subject to the same
       limitations, as if it were a Bank and had acquired its interest
       by assignment pursuant to paragraph (b) of this Section. This
       paragraph may not be amended without the written consent of any
       SPC which shall have made a Loan hereunder for as long as such
       Loan shall be outstanding.

                                       98

             SECTION 8.  Article 3 of the Credit Agreement is hereby
amended as follows:

             (a) Each of Sections 3.05(a) and 3.06 of the Credit
Agreement is amended by deleting each reference therein to (i) "1996"
and substituting in lieu thereof a reference to "1998" and (ii) "1997"
and substituting in lieu thereof a reference to "1999".

             (b) A new Section 3.20 shall be inserted after Section
3.19 and shall read as follows:

                  SECTION 3.20.  Year 2000.  Any reprogramming
       required to permit the proper functioning, in and following the
       year 2000, of (i) the material computer systems of the Borrower
       and the Subsidiaries and (ii) equipment containing embedded
       microchips (including systems and equipment supplied by others
       or with which the Borrower's or such Subsidiary's systems
       interface) that is material to the business of the Borrower and
       the Subsidiaries, taken as a whole, and the testing of all such
       systems and equipment, as so reprogrammed, has been completed.
       The cost to the Borrower and each of its Subsidiaries of such
       reprogramming and testing and of the reasonably foreseeable
       consequences of year 2000 to the Borrower and each of the
       Subsidiaries (including, without limitation, reprogramming
       errors and the failure of others' systems or equipment) will
       not, in the aggregate, result in an Event of Default or a
       material adverse change in the business, assets, condition
       (financial or otherwise) or results of operations of the
       Borrower and the Subsidiaries taken as a whole.  The computer
       and management information systems of the Borrower and each of
       the Subsidiaries are and, with ordinary course upgrading and
       maintenance, will continue for the term of this Agreement to be,
       sufficient to permit the Borrower and each of the Subsidiaries
       to conduct its business without the occurrence of any such
       material adverse change.

             SECTION 9.  Article 4 of the Credit Agreement is hereby
amended as follows:

       date of the proposed borrowing certifying as to attached
       resolutions of the Board of Directors of the Borrower and the

Banks under the Credit Agreement, as amended hereby, shall be equal to

             SECTION 11.  A new Exhibit F ("Form of Accession

                               [Form of]

                          ACCESSION AGREEMENT


                  AGREEMENT dated as of           , among [NAME OF
            ACCEDING BANK] (the "Acceding Bank"), DENTSPLY
            INTERNATIONAL INC., a Delaware corporation (the
            "Borrower"), and THE CHASE MANHATTAN BANK, a New York
            banking corporation ("Chase"), as administrative agent (the
            "Administrative Agent") for the Banks (as defined in the
            Credit Agreement referred to below).


      A.  Reference is made to the Amended and Restated 364-Day
Competitive Advance, Revolving Credit and Guaranty Agreement dated as
of October 21, 1999, (as amended or modified from time to time, the
"Credit Agreement"), among the Borrower, the guarantors named therein,
the banks named therein (individually a "Bank" and collectively the
"Banks"), the Administrative Agent and ABN AMRO BANK N.V., as
Documentation Agent.

      B.  Capitalized terms used herein and not otherwise defined
herein shall have the meanings assigned to such terms in the Credit
Agreement.

      C.  The Borrower has invited, and the Acceding Bank desires, to
become a party to the Credit Agreement and to assume the obligations of
a Bank thereunder.  The Acceding Bank is entering into this Agreement
in accordance with the provisions of the Credit Agreement in order to
become a Bank thereunder.

      Accordingly, the Acceding Bank, the Borrower and the
Administrative Agent agree as follows:

      SECTION 1.  Accession to the Credit Agreement. (a) The Acceding
Bank, as of the Effective Date,  hereby accedes to the Credit Agreement
and shall thereafter have the rights and obligations of a Bank
thereunder with the same force and effect as if originally named
therein as a Bank.

      (b) The Commitment of the Acceding Bank shall equal the amount
set forth opposite its signature hereto.

     SECTION 2.  Representations and Warranties, Agreements of
Acceding Bank, etc.  The Acceding Bank (a) represents and warrants that
it is legally authorized to enter into this Agreement; (b) confirms
that it has received a copy of the Credit Agreement, together with
copies of the most recent financial statements delivered pursuant to
Section 5.05 of the Credit Agreement and such other documents and
information as it has deemed appropriate to make its own credit
analysis and decision to enter into this

                                      109

Agreement; (c) confirms that it will independently and without reliance
upon the Administrative Agent or any Bank, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under the Credit Agreement;
(d) appoints and authorizes the Administrative Agent to take such action as
agent on its behalf and to exercise such powers under the Credit Agreement as
are delegated to the Administrative Agent by the terms thereof, together with
such powers as are reasonably incidental thereto; and (e) agrees that it will
perform, in accordance with the terms of the Credit Agreement, all the
obligations that by the terms of the Credit Agreement are required to be
performed by it as a Bank.

      SECTION 3.  Effectiveness.  (a) This Agreement shall become
effective on            (the "Effective Date"), subject to the
Administrative Agent's receipt of (i) counterparts of this Agreement
duly executed on behalf of the Acceding Bank and the Borrower and
(ii) if the Acceding Bank is organized under the laws of a jurisdiction
outside the United States, the forms specified in Section 2.22(a) of
the Credit Agreement duly completed and executed by the Acceding Bank.

      (b) Upon the effectiveness of this Agreement, the Administrative
Agent shall (i) record the information contained herein  in the
Register and (ii) give prompt notice thereof to the Banks.

      SECTION 4.  Counterparts.  This Agreement may be executed in
multiple counterparts, each of which shall constitute an original, but
all of which, when taken together, shall constitute but one instrument.

      SECTION 5.  Governing Law.  THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

      SECTION 6.  Severability.  In case any one or more of the
provisions contained in this Agreement should be held invalid, illegal
or unenforceable in any respect, none of the parties hereto shall be
required to comply with such provision for so long as such provision is
held to be invalid, illegal or unenforceable, but the validity,
legality and enforceability of the remaining provisions contained
herein and in the Credit Agreement shall not in any way be affected or
impaired.  The parties hereto shall endeavor in good-faith negotiations
to replace the invalid, illegal or unenforceable provisions with valid
provisions the economic effect of which comes as close as possible to
that of the invalid, illegal or unenforceable provisions.

      SECTION 7.  Notices.  All communications and notices hereunder
shall be in writing and given as provided in Section 10.01 of the
Credit Agreement.  All communications and notices hereunder to the
Acceding Bank shall be given to it at the address set forth under its
signature hereto, which information, together with the amount of the
Acceding Bank's Commitment, supplements Schedule 2.01 to the Credit
Agreement.

                                      110

     IN WITNESS WHEREOF, the Acceding Bank, the Borrower and the
Administrative Agent have duly executed this Agreement as of the day
and year first above written.
