VIEWRAY INCORPORATED AND MIRAX CORP.

UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

On July 23, 2015, ViewRay Technologies, Inc. (f/k/a ViewRay Incorporated), or the Company, and ViewRay, Inc. (f/k/a Mirax Corp.), or Mirax, consummated an Agreement and Plan of Merger and Reorganization, or Merger Agreement. Pursuant to the Merger Agreement, the stockholders of ViewRay contributed all of their equity interests in the Company to Mirax for shares of Mirax common stock, which resulted in the Company becoming a wholly-owned subsidiary of Mirax (the Merger).

Effective as of July 23, 2015, Mirax amended and restated its Certificate of Incorporation to increase its authorized common stock to 300,000,000 shares and 10,000,000 shares of “blank check” preferred stock, par value of $0.01 per share.

Upon closing of the Merger, under the terms of the Split-Off Agreement, dated July 23, 2015 among the Company, Mirax and Vesuvius Acquisition Sub, Inc., the acquisition subsidiary of Mirax (the Split-Off Agreement), and a general release agreement dated July 23, 2015 (the General Release Agreement), Mirax transferred all of its pre-Merger operating assets and liabilities to wholly- owned special-purpose subsidiary incorporated in Nevada, Mirax Enterprise Corp. (the Split-Off Subsidiary). Thereafter, Mirax transferred all of the outstanding shares of capital stock of the Split-Off Subsidiary to certain pre-Merger insiders of Mirax in exchange for the surrender and cancellation of shares of Mirax common stock held by such persons.

At the closing of the merger, the surviving corporation conducted a private placement offering of its securities for $26.7 million through the sale of 5,340,705 shares of the common stock of the surviving corporation, at an offering price of $5.00 per share. Existing ViewRay investors purchased $17.0 million of shares in the private placement offering. Certain shareholders of Mirax retained, after giving effect to the Split-Off, 1,000,005 shares of the common stock of the surviving corporation upon the private placement offering. The former stockholders of the Company collectively own approximately 92.2% of the outstanding shares of the surviving corporation’s common stock.

Immediately following the closing of the Merger, the surviving corporation’s outstanding shares of common stock (on a fully diluted basis) are owned as follows:

The Merger is being accounted for as a reverse-merger and recapitalization. The Company is the acquirer for financial reporting purposes, and Mirax is the acquired company under the acquisition method of accounting in

accordance with FASB ASC Topic 805, Business Combination. Consequently, the assets, liabilities and operations that will be reflected in the historical financial statements prior to the Merger will be those of the Company and will be recorded at the historical cost basis of the Company, and the consolidated financial statements after completion of the Merger will include the assets, liabilities and results of operations of the Company up to the day prior to the closing of the Merger and the assets, liabilities and results of operations of the combined company from and after the closing date of the Merger. The unaudited pro forma combined financial information is based on individual historical financial statements of the Company and Mirax prepared under U.S. GAAP and is adjusted to give effect to the Merger Agreement.

The historical financial statements have been adjusted in the pro forma combined financial statements to give effects to events that are (1) directly attributable to the Merger, (2) factually supportable, and (3) with respect to the statement of operations, expected to have a continuing impact on the combined entities. The unaudited pro forma combined statements of operations eliminate any non-recurring charges directly related to the Merger that the combined entities incur upon completion of the Merger.

Due to different fiscal periods for the Company and Mirax, the June 30, 2015 unaudited pro forma combined balance sheet is based upon the historical balance sheet data of the Company as of June 30, 2015, and the historical balance sheet data of Mirax as of May 31, 2015, giving effect to events that are directly attributable to the Merger, as if the Merger were consummated as of June 30, 2015. The unaudited pro forma combined statements of operations combine the Company’s historical statements of operations for the year ended December 31, 2014 and the six months ended June 30, 2015 with Mirax historical statements of operations for the year ended November 30, 2014 as well as the six months ended May 31, 2015, giving effect to the events that are directly attributable to the Merger, as if the Merger were consummated at the beginning of the year ended December 31, 2014, and that are expected to have a continuing impact on the combined company. The difference in fiscal periods between the Company and Mirax does not result to material misstatement in the combined pro-forma financial statements.

The unaudited pro forma combined financial information does not purport to represent what the combined company’s results of operations or financial position would actually have been had the Merger occurred on the dates described above or to project the combined company’s results of operations or financial position for any future date or period.

The unaudited pro forma combined financial information should be read together with (1) ViewRay Incorporated audited balance sheets as of December 31, 2014 and 2013 and the related statements of operations, statements of convertible preferred stock and stockholders’ deficit and statements of cash flows for the years ended December 31, 2014 and 2013 and the accompanying notes, and (2) Mirax Corp. unaudited balance sheet as of May 31, 2015 and the related statements of operations and statements of cash flows for the six months ended May 31, 2015 and 2014 and the accompanying notes.
