NOW THEREFORE, in consideration of the mutual covenants and promises contained in this Amendment No. 2, the Parties agree as follows:

1. Amendment of 3D Line Development Obligations. Section 2.1(a) of the Agreement is hereby amended to read in full as follows:

“2.1 Development of 60-Leaf MLCs. (a) 3D Line will perform a development program (the “Program”) directed toward the development of 60-Leaf MLCs that meet the Specifications (including the documents referenced therein). The Program will be performed in two iterations with 3D Line delivering to ViewRay: (i) within four (4) months after the Effective Date, complete design plans for the 60-Leaf MLCs that are suitable for manufacturing 60-Leaf MLCs that conform to the Specifications; (ii) [intentionally omitted]; (iii) within one (1) month after ViewRay makes the payment under Section 2.2(b) “final” design plans for the 60-Leaf MLCs that conform to the Specifications that include detailed engineering and fabrication information sufficient to enable commercial scale manufacture; and (iv) within two (2) months after ViewRay makes the payment under Section 2.2(c), but not later than January 15, 2010 unless ViewRay notifies 3D Line that ViewRay is willing to accept a later delivery date, three (3) 60-Leaf MLCs that conform to the Specifications (each, a “Deliverable”).

2. Amendment to Specifications for purposes of ViewRay Development Funding Obligation. Section 2.1 of the Agreement is hereby amended to add new Section 2.1(d) to the end of Section 2.1 to read in full as follows:

“(d) It is understood and agreed that for purposes of the 60-Leaf MLC Deliverables that 3D Line will provide to ViewRay pursuant to Section 2.1(a)(iv), satisfaction of the Specifications under Section 2.1(c) shall be made (i) without reference to the requirement that such 60-Leaf MLCs be capable of [***] (as provided in Section 2.8 of Attachment 1); (ii) with Section 2.7 of Attachment 1 being revised to provide that the MLC may employ [***] (rather than [***] as currently provided in Section 2.7 of Attachment 1); (iii) with Section 2.12 of Attachment 1 being revised to provide that the [***] (rather than [***] as currently provided in Section 2.12 of Attachment 1); and (iv) with Section 2.14 of Attachment 1 being revised to provide that the [***] (rather than [***] as currently provided in Section 2.14 of Attachment 1). It is understood and agreed that this Section 2.1(d) shall not apply to the 60-Leaf MLCs to be supplied to ViewRay pursuant to Section 2.5. It is further understood and agreed that the 60-Leaf MLC

Deliverables that 3D Line will provide to ViewRay pursuant to Section 2.1(a)(iv) must be delivered to ViewRay by January 15, 2009 unless ViewRay notifies 3D Line in accordance with Section 2.1(a)(iv) that ViewRay is willing to accept a later delivery date and failure to deliver such Deliverables by such date (or such later date specified by ViewRay in accordance with Section 2.1(a)(iv)) shall permit ViewRay to terminate this Agreement in accordance with the last sentence of Section 2.1(b) and demand a refund of the [***] payment under Section 2.2(b).”

3. Amendment of ViewRay Funding Obligation. Section 2.2 of the Agreement is hereby amended to read in full as follows:

“2.2 Development Funding. (a) ViewRay will pay 3D Line the then U.S. Dollar equivalent of €[***] within three (3) days of the Effective Date for the engineering services required to develop/ deliver the Deliverable described in Section 2.1(a)(1).

The fully-allocated cost of manufacturing shall not include [***] (that 3D Line or any third party may have) or [***] including, by way of example only, [***]. It is understood and agreed that in the event and to the extent that the Supply Agreement the parties enter into pursuant to Section 2.5 is structured so that 3D Line does not manufacture the leaves that are used in the MLCs or does not manufacture other subassemblies for such 60-Leaf MLCs that are within the scope of 3D Line’s responsibilities during the Program, then the pricing under Section 2.5 and the Supply Agreement shall be adjusted so that the costs of leaves or other subassemblies manufactured or supplied by any third party if paid by ViewRay shall be deducted from the price paid 3D Line for such MLCs; the intention of the parties being that 3D Line shall be compensated for the work it actually performs with respect to the manufacture and supply of the 60-Leaf MLCs and shall not be compensated at any “mark-up” for work performed by third parties with respect to such 60-Leaf MLCs, such third party work (if not paid to such third party by ViewRay) being priced at the direct cost to 3D Line for such leaves or other subassemblies.”

years from the date ViewRay takes delivery of [***] 60-Leaf MLCs from 3D Line, ViewRay will provide 3D Line with a right of first offer to supply ViewRay’s requirements for 60-Leaf MLCs on the terms and conditions to be set forth in a Supply Agreement to be negotiated, executed and delivered by the parties after the Effective Date (the Supply Agreement). Attached hereto as Attachment 2 is a term sheet that sets forth certain of the terms that the parties have agreed will be incorporated into the Supply Agreement.

If the parties do not agree with respect to termination of the Program, they shall resolve such dispute using the procedure specified in Section 10.2(a)-(b).

(c) It is understood and agrees that the 60-Leaf MLCs delivered pursuant to Section 2.1(a)(iv) shall not conform to the Specifications for purposes of this Section 2.5 and that accordingly ViewRay shall not be obligated to observe the provisions of Section 2.5(a) with respect to purchasing its [***] 60-Leaf MLCs from 3D Line or providing 3D Line with a right of first offer to supply ViewRay’s requirements for 60-Leaf MLCs under Attachment 2 or the Supply Agreement. Notwithstanding the foregoing, 3D Line shall be obligated to supply if ViewRay and 3D Line mutually agree upon terms for 3D Line to manufacture and deliver three (3) 60-Leaf MLCs, the provisions of Section 2.5(a) with respect to ViewRay purchasing its initial [***] 60-Leaf MLCs from 3D Line and providing 3D Line with a right of first offer to supply ViewRay’s requirements for 60-Leaf MLCs under Attachment 2 or the Supply Agreement shall take effect.”
