WHEREAS, the Advisors have rendered certain services (the “Financial Services”) to the Company and the Borrowers in connection with the negotiation of the loans contemplated by the Amended and Restated Senior Facilities Agreement and the Amended and Restated Mezzanine Facilities Agreement (collectively the “Finance Agreements”) in respect of which the Borrowers have agreed to pay a fee;

WHEREAS each of the Borrowers acceded to the Finance Agreements at or around the time that the Company completed the acquisition of Sirona Dental Systems Beteiligungs und Verwaltungs GmbH (“Sirona BV”), and indirectly acquired Sirona KG and Sirona (the “Acquisition”);

WHEREAS the Advisors have in addition provided certain other services (the “Transaction Advisory Services”) to the Company in connection with the Acquisition; and

WHEREAS the Financial Services and the Transaction Advisory Services were rendered through and until the completion of the Acquisition, and thereupon ceased.

WHEREAS it is anticipated that Sirona KG will as a result of certain transactions taking place before the date hereof merge with Sirona BV.

NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement have agreed as follows:

1. Services. The Advisors have performed Financial Services for the benefit of the Company and the Borrowers and the Transaction Advisory Services for the benefit of the Company, each as further described in Section 2 below.

2. Fees and Expenses.

(a) The Company and the Borrowers hereby agree to pay, in connection with the drawdown of the borrowings under the Finance Agreements, to the Advisors (or, at the request of an Advisor, to its designee(s)), (i) a fee for the Financial Services provided (“Finance Fee”), such fee to be allocated amongst them in proportion as their respective borrowings

pursuant to the Finance Agreements, in aggregate equal to five million, five hundred thousand euro (€5,500,000), plus irrecoverable VAT in each case where it is applicable, and (ii) all reasonable out-of-pocket expenses and VAT on those expenses (collectively, the “Finance Expenses”) incurred by the Advisors and their Affiliates in rendering the Financial Services.

(b) The Company hereby agrees to pay, in connection with the consummation of the Acquisition, to the Advisors (or, at the request of an Advisor, to its designee(s)), (i) a fee for Transaction Advisory Services provided in relation to the Acquisition (“Advisory Fee”) of an amount equal to four million, five hundred thousand euro (€4,500,000), plus VAT in each case where it is applicable, and (ii) all reasonable out-of-pocket expenses (including fees of certain consultants) and irrecoverable VAT on those expenses (collectively, the “Transaction Advisory Expenses”) incurred by the Advisors and their Affiliates in rendering the Transaction Advisory Services.

(c) The Financial Services and the Transaction Advisory Services are collectively referred to as the “Transaction Services”, The Finance Fee and the Transaction Advisory Fee are together the “Transaction Services Fees”.

(e) The Financial Services and the Transaction Advisory Services provided shall be evidenced by documentation recording details of their performance to be agreed upon between the Company, the Borrowers and the Advisors, such documentation to include by way of example: details of the date, time, location, type of service and officer of the Advisors performing the services.

(f) The Financial Services include, without limitation, the following:

(i) advice in relation to financing alternatives for the Acquisition, including discussions and preliminary negotiations with various potential providers of senior and mezzanine debt; (ii) assistance in negotiating heads of terms with JP Morgan PLC and others as lead arrangers of senior and mezzanine debt; and (iii) assistance in negotiation of the Finance Agreements.

3. Recharge of Fees. The Advisors acknowledge that the Company and the Borrowers may recharge to their Affiliates such proportion of the Transaction Services Fees and Transaction Expenses as relates to the benefit (if any) received by such Affiliates from the relevant Transaction Services and the Advisors shall, if requested, provide the Company or the Borrowers with such evidence as they may reasonably request of the services provided for their Affiliates’ benefit.

4. Liability. Neither the Advisors nor any of their Affiliates, partners, members, employees or agents (collectively, the “Advisor Group”) shall be liable to any of the Company or the Borrowers or their Affiliates for any loss, liability, damage or expense (collectively, “Loss”) arising out of or in connection with the performance of services contemplated by this Agreement, except to the extent that such Losses arise out of, relate to, or result directly or indirectly from the gross negligence or willful misconduct of one or more members of the Advisor Group. The Advisors make no representations or warranties, express or implied, in respect of the services provided by the Advisor Group. Except as the Advisors may otherwise agree in writing after the date hereof: (a) each member of the Advisor Group shall have the right to, and shall have no duty (contractual or otherwise) not to, directly or indirectly (i) engage in the same or similar business activities or lines of business as the Company or the Borrowers or (ii) do business with any client or customer of the Company or the Borrowers; (b) no member of the Advisor Group shall be liable to the Company or the Borrowers for breach of any duty (contractual or otherwise) by reason of any such activities or of such member’s participation therein; and (c) in the event that any member of the Advisor Group acquires knowledge of a potential transaction or matter that may be a corporate opportunity for any of the Company or the Borrowers, on the one hand, and an Advisor, on the other hand, or any other Person, no member of the Advisor Group shall have any duty (contractual or otherwise) to communicate or present such corporate opportunity to the Company or the Borrowers, and, notwithstanding any provision of this Agreement to the contrary, no member of the Advisor Group shall be liable to the Company or the Borrowers for breach of any duty (contractual or otherwise) by reason of the fact that any member of the Advisor Group directly or indirectly pursues or acquires such opportunity for itself, directs such opportunity to another Person, or does not present such opportunity to the Company or the Borrowers. Subject to the above, no member of the Advisor Group shall be liable to any of the Company or the Borrowers for any indirect, special, incidental or consequential damages, including lost profits or savings, whether

or not such damages are foreseeable, or in respect of any liabilities relating to any third party claims (whether based in contract, tort or otherwise) other than for the Claims (as defined in Section 5 below) relating to the services which may be provided by the Advisors hereunder.

5. Indemnity. The Company and the Borrowers shall jointly and severally defend, indemnify and hold harmless each member of the Advisor Group from and against any and all Losses arising from any claim by any Person with respect, or in any way related, to this Agreement (including attorneys’ fees) (collectively, “Claims”) resulting from any act or omission of any member of the Advisor Group, except to the extent that such Losses are finally adjudicated to arise out of, relate to, or result directly or indirectly from the gross negligence or willful misconduct of one or more members of the Advisor Group. Subject to the above, the Company and the Borrowers shall jointly and severally defend at their own cost and expense any and all suits or actions (just or unjust) which may be brought against any of the Company and the Borrowers and any member of the Advisor Group or in which any member of the Advisor Group may be impleaded with others upon any Claims, or upon any matter, directly or indirectly, related to or arising out of this Agreement or the performance hereof by the Advisor Group.

6. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal, or unenforceable in any respect under applicable law or rule in any jurisdiction, such invalidity, illegality, or unenforceability shall not effect the validity, legality, or enforceability of any other provision of this Agreement in such jurisdiction or affect the validity, legality, or enforceability of any provision in any other jurisdiction. Instead, this Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal, or unenforceable provision had never been contained herein.
