exhibit 10. 16 manufacturing services agreement this agreement is entered into as of the 23rd day of november, 2016 by paramit corporation, a california corporation ( referred to in this agreement as “ paramit ” or “ supplier ” ), and quanterix, inc., a delaware corporation ( referred to in this agreement as “ customer ” ). each of paramit and customer may be referred to herein as a “ party ” and are jointly referred to as the “ parties. ” recitals whereas, customer intends to develop and commercialize certain products and wishes to contract with a contract manufacturing organization for the further refinement, manufacture and supply of such products ; and whereas, paramit has manufacturing and related services experience and expertise and owns a facility that is or would be suitable for production of such products ; and whereas, customer desires to retain paramit as a supplier of the product ( as defined below ), and supplier desires to supply such product and perform services for customer on the terms and conditions set forth in this agreement ; and now, therefore, in consideration of the foregoing premises and of the mutual covenants of the parties hereinafter set forth, the parties hereto agree as follows : 1. definitions deterministic acceptance criteria : paramit procures material to customer specifications, assembles and tests finished assemblies and product also to customer specifications. an acceptance criterion that directly evaluates the functional performance of the product to the customer specifications is called “ deterministic ”. non acceptance will point to a particular part or function as being defective or inoperative. examples : pressure test, repeatability of a positioning system, bearing pre - load measurement etc. to contrast, an example of a non - deterministic criterion would be one where the customer ’ s application software fails but it does not point to any failing part of the machine. the particular test might fail owing to establishment of specification limits that are tighter than what the machine design is capable of delivering, or the variance in the consumables. another example would be when the customer constructs a test whose result is a derivative of several parameters and therefore a failure of this test may not indicate where the problem lies or whether there is a problem at all. “ acceptance period ” means [ * * * ] after shipment of product from paramit. “ calendar quarter ” means each period of three consecutive calendar months ending on march 31, june 30, september 30 or december 31. form : sal - f
