 Exhibit 10.32 
 SUPPLEMENT AGREEMENT TO SERVICE AGREEMENT 
 by and between 

Sirona Dental GmbH, Wasserfeldstraße 30, A-5020 Salzburg, Austria, as employer 

(hereinafter the “Company”), 
 Sirona Dental Systems, Inc., 30 -30 47th Avenue, Suite 500, Long Island City, NY 11101, USA 
 (hereinafter the “Guarantor”) 
 and 

Mr Jost C. Fischer, Buchenweg 16, 83098 Brannenburg, Germany, as employee 
 (hereinafter the “Member of the Management Board” or the “Member”) 
 Preliminary Remarks 
 The Company and the Member of the Management Board have entered into
an executive service agreement (Geschäftsführer-Dienstvertrag) dated 10 October 2007, which has been amended in the meantime and the Guarantor has become a party to this agreement (as amended, the “Current Executive
Service Agreement”). The Company, the Member of the Management Board and Guarantor wish to supplement the Current Executive Service Agreement as follows: 
 § 1 
 Supplement 
 A new paragraph 6 and a new paragraph 7 shall be added to § 2 “Compensation” of the Current Executive Service Agreement, which reads as follows: 

 

	“6.	As the Member of the Management may provide his work under this Agreement also partially for the Guarantor, the parties agree that all time the Member of the Management
Board may work under this Agreement in Austria shall be deemed to be work only for the Company (including work in connection with a management service agreement between the Company and the Guarantor), but not for the Guarantor. The yearly salary and
the bonus according to § 2 paras. 1 and 2 of this Agreement shall be paid by the Guarantor pro rata to the days the Member of the Management Board has worked for the Guarantor compared to the total days to be worked under this
Agreement (“Guarantor Portion”). The remaining portion of the yearly salary and the bonus according to § 2 paras. 1 and 2 of this Agreement shall be paid by the Company. In order to facilitate the payment mechanism,
it is agreed that Guarantor shall, with regard to salary according to § 2 para 1 of this Agreement, be obliged to pay to the Member of the Management Board a fixed amount on a monthly basis in the amount of 20% of the total salary; accordingly,
the remaining part of the salary to be paid by the Company to the Member of the Management Board will amount to 80% of such salary. Within 30 days following the end of a calendar year, Guarantor, or as the case may be, the Company, shall, on the
basis of the records duly maintained by the Company for such calendar year, compensate the respective other party for the difference between the portion of salary actually paid and the pro rata portion to be paid for such calendar year. The Member
of the Management Board declares to accept the agreed payments from Guarantor. Therefore, by receipt of payments of Guarantor, the respective payment obligations of Company shall be satisfied. For avoidance of doubt, the Guarantor’s obligation
to make certain payments under this Agreement does not affect the payment obligations of the Company under this Agreement. Therefore, if Guarantor is in default with payments, both the Company and the Guarantor shall be jointly and severally
(solidarisch) liable for the respective claims. 








 To further specify the work the Member of the Management Board provides for the Guarantor
under this Agreement, the Guarantor and the Member of the Management Board shall conclude the agreement attached as Annex 2.6, which shall be an integral part of this Agreement. 

For the avoidance of doubt, all other rights and obligations of the Member of the Management Board under and in connection with this
Agreement, shall not be split and, therefore, remain to the full extent vis-à-vis the Company and/or the Guarantor, as they were. In particular, the authority to issue instructions (Weisungsrecht) to the Member of the Management Board
with regard to the performance of this Agreement shall remain with the Company. 
  

	7.	The Member of the Management Board shall be subject to tax equalization. Tax equalization shall mean and ensure that the Member of the Management Board remains neutral
from a tax and social security perspective with respect to (i) compensation received by the Member of the Management Board from the Guarantor and/or the Company, including any U.S. tax on salary, bonuses, share based compensation (including
effects in case of exercises), and (ii) the indirect investment of the Member of the Management Board in the Guarantor; provided that the Company and the Guarantor shall be obliged to make any payments with respect to such tax equalization for
any given calendar year only if during such calendar year (x) the following conditions under (1) and (4) have been satisfied and (y) only in respect of the tax equalization regarding the Member’s indirect investment in the
Guarantor according to 7. (ii), also the following conditions under (2) and (3) have been satisfied: 

  

	 	(1)	either (A) the only days the Member has been physically present in the United States during such calendar year are days the Member performed services for the
Guarantor in the United States and any days immediately prior to or immediately after any days on which the Member performed such services, or (B) the sum of (i) the number of days the Member has been physically present in the United
States during such calendar year, (ii) the number of days the Member has been physically present in the United States in the first preceding calendar year multiplied by 1/3, and (iii) the number of days the Member has been physically
present in the United States in the second preceding calendar year multiplied by 1/6, does not equal or exceed 183; 

  

	 	(2)	other than the services performed for the Guarantor, the Member has not engaged in activities constituting trade or business in the United States (including through an
entity treated as a partnership for United States federal income tax purposes).; 

  

	 	(3)	Dental Innovations BVBA has not engaged in a United States trade or business (including through an entity treated as a partnership for United States federal income tax
purposes); and 

  

	 	(4)	the Member has not applied for permanent resident status in the United States. 

 In case of distributions from Dental Innovations BVBA to the Member, the tax equalization according to 7. (ii) shall become payable (i) for an aggregate distribution amount to the Member of up
to US$ 5.0 million of cash or assets during the three-year period beginning on the date hereof and (ii) unless the Parties agree in writing to a different amount prior to the expiry of the first three-year period, an additional aggregate
distribution amount to the Member of up to US$ 5.0 million of cash or assets during the consecutive three-year period beginning upon expiry of the first three-year period (i.e. distributions to the Member in an aggregate amount of up to
US$ 10.0 million are subject to tax equalization over such six-year period). 
 The Member of the Management Board will pay
the same amount of income taxes (referred to as “hypothetical tax liability”) as he would have paid had he performed all of his duties in Austria and did not perform the duties/time spend in the United States of America and been subject to
a salary split mentioned above. 
 The Company shall provide and pay for all tax advice in this regard – especially for the
calculation of the “hypothetical tax liability” - and will engage PricewaterhouseCoopers to prepare the U.S. tax returns, as applicable. In addition, the Company will engage PricewaterhouseCoopers to report to the Austrian tax advisor of
the Member of the Management Board all relevant information being caused by the salary split and the tax equalization mentioned above, which are necessary or helpful to prepare and file the Austrian income tax returns of the Member of the Management
Board.” 
 All other terms of the Current Executive Service Agreement remain unchanged. 







 § 2 
 Miscellaneous 
  

	1.	Modifications of, or amendments to, this agreement shall be made in writing to be effective. The same applies for this clause. 


 

	2.	The parties may comply with the requirement of written form as agreed in this agreement by using fax, telex or telecopy, if the author of the document is identifiable
from the document. 

  

	3.	Should any provision of this agreement be or become invalid, this does in no way influence the validity of the remaining provisions. The parties undertake to agree
without undue delay a provision instead of the invalid provision which comes as nearest to the economic purpose of the invalid provision and the purpose the parties have intended. 


 

	4.	In case of an discrepancies between this agreement and Annex 2.6, this agreement shall prevail. 


 

	5.	This agreement is governed by the laws of Austria. Any dispute arising out of this agreement shall fall within the jurisdiction of the competent court for the court
district of Salzburg.
