Item 2.02.  Results of Operations and Financial Condition.

        On October 26, 2005, Varian Medical Systems, Inc. (the "Company")
announced that: Varian Medical Systems Reports Growth in Earnings, Revenues, Net
Orders, and Backlog for Fiscal Year 2005; Company Raises Guidance for Fiscal
2006. A copy of the press release is attached as Exhibit 99.1 and incorporated
herein by reference.

        The press release contains the Company's Outlook for fiscal year 2006
which includes certain forward-looking numbers, including the Company's earnings
per diluted share outlook for first quarter of fiscal year 2006 and for the full
fiscal year 2006, that may constitute non-GAAP financial measures due to the
fact that these numbers do not include the impact of expensing stock options
under the Financial Accounting Standards Board's Statement 123R ("FAS 123R").
Reconciliation of the non-GAAP forward-looking measures is contained in the
Outlook section of the press release. Notwithstanding the fact that these
forward-looking numbers exclude the impact of expensing stock options,
management believes that these forward-looking numbers are useful to investors
because they provide insight into management's current expectations for the
performance of the Company's business and for understanding of comparative
operating performance over Management also believes such information is useful
because it represents the manner in which the Company's business is currently
being managed.

        The press release may also contain other non-GAAP financial measures. If
any other non-GAAP financial measures are presented, reconciliation to GAAP is
also included. Management uses any such non-GAAP financial measures to gain an
understanding of its comparative operating performance.
