On July 17, 2012, SUPERVALU INC. (the “Company”) held its 2012 Annual Meeting of Stockholders (the “Annual Meeting”). At the Annual Meeting, the Company’s stockholders approved the SUPERVALU INC. 2012 Stock Plan (the “2012 Stock Plan”), effective as of July 17, 2012. The 2012 Stock Plan was previously approved by the Company’s Board of Directors on April 17, 2012, subject to stockholder approval.

The purpose of the 2012 Stock Plan is to enable the Company to attract and retain employees, officers, non-employee Directors, consultants, independent contractors and advisors who are capable of assuring the future success of the Company, to offer such persons incentives to put forth maximum efforts for the success of the Company’s business and to compensate such persons through various stock-based and other arrangements and provide them with opportunities for stock ownership in the Company, thereby aligning the interests of such persons with the Company’s stockholders. The 2012 Stock Plan, which is administered by the Leadership Development and Compensation Committee of the Company’s Board of Directors, authorizes the grant of non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards, dividend equivalents, stock awards and other stock-based awards. The term of each award granted under the 2012 Stock Plan may not be longer than 10 years from the date of grant. The aggregate number of shares of the Company’s common stock authorized and reserved for issuance under the 2012 Stock Plan is the sum of (i) 29,500,000 and (ii) any shares subject to awards under the Company’s 2007 Stock Plan as of May 22, 2012 that on or after July 17, 2012, cease to be subject to such awards (other than because they are exercised for or settled in vested and nonforfeitable shares), subject to adjustments as set forth in the 2012 Stock Plan.

The Company’s Board of Directors may amend, alter, suspend, discontinue or terminate the 2012 Stock Plan at any time, except as provided in the 2012 Stock Plan. Unless earlier terminated by the Board of Directors, no awards may be granted under the 2012 Stock Plan after April 17, 2022.

This summary of the 2012 Stock Plan is not complete and is qualified in its entirety by reference to the full text of the 2012 Stock Plan, a copy of which is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference herein. A more detailed summary of the 2012 Stock Plan can be found in the Company’s Definitive Proxy Statement on Schedule 14A, which was filed with the Securities and Exchange Commission and mailed to stockholders on June 4, 2012 (the “2012 Proxy Statement”).

Approval of Amendments to the Directors’ Deferred Compensation Plan

At the Annual Meeting on July 17, 2012, the Company’s stockholders approved amendments to the SUPERVALU INC. Directors’ Deferred Compensation Plan (2009 Statement) (the “DDCP”), effective as of July 17, 2012. The amendments to the DDCP were previously approved by the Company’s Board of Directors on April 17, 2012, subject to stockholder approval. The amendments to

the DDCP increased the number of shares of common stock available for issuance under the DDCP by 1,800,000 shares, from 1,000,000 shares to 2,800,000 shares, and made certain administrative changes, including: (i) excluding non-employee Directors who were former employees of the Company from participating in the DDCP, (ii) updating the timing of the annual deferred stock retainers credited to new and existing non-employee Directors and (iii) providing for the crediting of supplemental deferred stock retainers.

The DDCP allows eligible non-employee Directors to elect to defer all or a portion of the compensation payable to them for service on the Company’s Board of Directors into unfunded bookkeeping accounts for payment to them in cash and/or common stock after they cease serving as a Director. The DDCP also allows the Company to make conditional awards of unfunded, book-entry common stock to eligible non-employee Directors as compensation for their service as Directors with payment to be made to them in cash or common stock after they cease serving as a Director. Under the DDCP, Director compensation and conditional awards may be deferred until termination of service as a Director or, subject to certain restrictions, such later date as may be specified by the Director. The DDCP is administered by the Corporate Governance and Nominating Committee of the Board of Directors. Any Director who is not currently, and was not formerly, an employee of SUPERVALU is eligible to participate in the DDCP.

This summary of the DDCP and the amendments to the DDCP is not complete and is qualified in its entirety by reference to the full text of the DDCP, a copy of which is attached as Exhibit 10.7 to this Current Report on Form 8-K and is incorporated by reference herein. A more detailed summary of the amendments to the DDCP can be found in the 2012 Proxy Statement.

At the Annual Meeting on July 17, 2012, the Company’s stockholders approved the following amendment to the Company’s Restated Certificate of Incorporation, which was previously approved by the Board of Directors on May 5, 2012, subject to stockholder approval.
