Section 5—Corporate Governance and Management

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year

On June 15, 2016, the Board of Directors of Oracle adopted amendments to Oracle’s Amended and Restated Bylaws (the “Bylaws”) to implement proxy access. As amended, the Bylaws include a new Section 1.12 permitting a stockholder, or a group of up to 20 stockholders, owning continuously for at least three years a number of Oracle shares that constitutes at least 3% of Oracle’s outstanding shares, to nominate and include in Oracle’s proxy materials director nominees constituting up to the greater of two individuals or 20% of the Board, provided that the stockholder(s) and the nominee(s) satisfy the requirements specified in the Bylaws. Under the amended Bylaws, notice of a proxy access nomination must be delivered to Oracle’s Secretary at Oracle’s principal executive offices by the close of business not less than 120 days nor more than 150 days prior to the date on which Oracle first mailed its proxy materials for the prior year’s annual meeting of stockholders.

The amended Bylaws also reflect certain conforming and clarifying changes, including: (1) conforming and clarifying changes in Section 1.11 of the Bylaws; (2) clarifying changes in Section 3.01 of the Bylaws; and (3) minor changes throughout the Bylaws to reflect Oracle’s management structure of two Chief Executive Officers, one of whom is the Principal Financial Officer.

The foregoing description is qualified in its entirety by reference to the full text of the Bylaws, a copy of which is filed as Exhibit 3.02 to this report and is incorporated herein by reference.
