AMENDMENT 

TO 

DEVELOPMENT AND SUPPLY AGREEMENT 

This Amendment ( “Amendment”) to the Development and Supply Agreement by and between Intuitive Surgical, Inc.
(“Intuitive”), and Luna Innovations Incorporated (“Luna”, and collectively with Intuitive, the “Parties”) dated June 11, 2007 (the “Original Agreement”), is made and entered
into as of January 12, 2010. 
 BACKGROUND 
  


	A.	The Parties amended the Original Agreement by an Amendment No. X dated May 20, 2008, to replace Exhibit 2.1 to the Original Agreement. The Original Agreement as
amended by Amendment No. X shall be referred to as the “Agreement”. 

  

	B.	As a part of settlement of certain litigation between Luna and Hansen Medical, Inc. (“Hansen”), Luna seeks to modify certain provisions of the
Agreement such that it may provide Hansen with a co-exclusive (with Intuitive) license to its fiber optic shape sensing/localization technology within a certain field as defined in a License Agreement Between Intuitive and Luna having the same date
as this Amendment (the “New Intuitive License”). 

  

	C.	In connection with this settlement, Luna and Intuitive desire to amend the Agreement to allow the co-exclusive license of certain technologies by Luna to Hansen and to
permit Luna to engage in certain development work for Hansen, as well as modify the patent enforcement provisions and make various other changes to the Agreement desired by the Parties. 


 

	D.	On December 11, 2009, Luna met and satisfied the Second Milestone contemplated by the Agreement, thus completing its development obligations. The Parties, however,
expect that Intuitive may desire Luna to perform further development work under the Agreement and this Amendment provides for that possibility in the future. 


 

	E.	All terms not defined in this Amendment shall have the meanings assigned to them in the Agreement or the New Intuitive License (and any defined in both shall have the
meaning assigned in the latter). 

  

	F.	Now, therefore, the Parties hereby agree to the following terms and conditions, the adequate mutual consideration for which is hereby acknowledged.
