 (a) During the term of this Agreement, VIEWRAY may from time to time seek services from Vendor. For each “Project” to be
undertaken by Vendor pursuant to this Agreement, the parties will prepare a “Work Statement” in substantially the form attached as Attachment A that describes the (i) services that
Vendor will provide (“Services”) deliverables that Vendor will be responsible for delivering to VIEWRAY (“Deliverable(s)”), (ii) delivery schedule for the Deliverables, (iii) pricing terms,
(iv) acceptance test procedures for the Deliverables, (v) work plan for the Project, and (vi) VIEWRAY’s responsibilities in connection with the Project. Each Work Statement will be prepared based upon the requirements and

(b) VIEWRAY hereby retains Vendor and Vendor hereby agrees to perform the work described in the attached Work Statements. 

1.2 Changes. VIEWRAY may request amendments to a Work Statement to effect changes in the Services. If VIEWRAY wishes to make a change it shall notify
Vendor of the requested change specifying the change with sufficient details to enable Vendor to evaluate it (a “Change Request”). Within fifteen Business Days following the date of Vendor’s receipt of a VIEWRAY
Change Request, Vendor shall deliver a document that: (i) assesses the impact of the change on the total cost of the Services and the schedule, and (ii) incorporates a description of the requested change and its cost (a “Change
Control Document”). If VIEWRAY accepts the Change Control Document, then the provisions of this Agreement shall be deemed amended to incorporate such change in accordance with the Change Control Document. The price stated in the Change
Control Document shall be deemed an increase in the charges specified in the then applicable Work Statement.

(“Acceptance”) of the Deliverable by executing a Deliverable acceptance certificate within the time period specified in the applicable Work Statement. If VIEWRAY rejects the Deliverable, VIEWRAY shall provide Vendor with
notice of rejection, including a reasonably specific description of the failure alleged. Vendor shall have the time period specified in the applicable Work Statement following its receipt of VIEWRAY’s notice of rejection in which to

redelivered Deliverable in which to accept or reject the Deliverable. If VIEWRAY accepts the deliverable it shall deliver a Deliverable acceptance certificate to Vendor within the time period specified in the applicable Work Statement. If VIEWRAY
