On April 24, 2015, at the 2015 Annual Meeting of Stockholders (the “Annual Meeting”) of Crossroads Systems, Inc. (the “Company”), the Company’s stockholders approved (i) an amendment to the Company’s 2010 Stock Incentive Plan (the “Plan”) to increase the number of shares of the Company’s common stock subject to the Plan from 3,750,000 shares to 5,250,000 shares; and (ii) an amendment to the Plan to make certain corporate governance and other changes and the re-approval of the material terms of the performance goals included in the Plan. A copy of the Plan reflecting these amendments is filed herewith as Exhibit 10.1 and incorporated herein by reference.

On April 27, 2015, the Company filed a Certificate of Amendment to the Company’s Certificate of Incorporation with the Secretary of State of the State of Delaware to amend the Certificate of Incorporation to include a protective amendment designed to protect the tax benefits of the Company’s net operating loss carryforwards (the “Protective Amendment”). The Protective Amendment was approved by the Company’s stockholders at the Annual Meeting held on April 24, 2015, as described in more detail below.

The Protective Amendment restricts certain transfers of the Company’s common stock in order to protect the tax benefits of the Company’s net operating loss carryforwards. The Protective Amendment’s transfer restrictions generally restrict any direct or indirect transfers of the Company’s common stock that increase the direct or indirect ownership of the Company’s common stock by any Person (as defined in the Protective Amendment) from less than 4.99% to 4.99% or more of the Company’s common stock, or increase the percentage of the Company’s common stock owned directly or indirectly by a Person owning or deemed to own 4.99% or more of the Company’s common stock. Further, any direct or indirect transfer attempted in violation of the Protective Amendment will be void as of the date of the prohibited transfer as to the purported transferee. The foregoing description of the Protective Amendment does not purport to be complete and is qualified in its entirety by reference to the complete text of the Protective Amendment, which is filed herewith as Exhibit 3.1 and incorporated herein by reference.

The following matters were submitted to a vote of the Company’s stockholders at the Annual Meeting held on April 24, 2015: (i) the election of five directors to serve until the Company’s 2016 Annual Meeting of Stockholders and until their successors are duly elected and qualify; (ii) the ratification of the appointment of PMB Helin Donovan, LLP as the Company’s independent registered public accounting firm for the fiscal year ending October 31, 2015; (iii) the approval of the Protective Amendment; (iv) the approval of the Company’s Tax Benefit Preservation Plan (a shareholder rights plan) designed to protect the tax benefits of the Company’s net operating loss carryforwards; (v) the approval of an amendment to the Plan to increase the number of shares of the Company’s common stock subject to the Plan from 3,750,000 shares to 5,250,000 shares; and (vi) the approval of an amendment to the Plan to make certain corporate governance and other changes and the re-approval of the material terms of the performance goals included in the Plan. The number of shares of the Company’s common stock and Series F convertible preferred stock outstanding and eligible to vote as of March 13, 2015, the record date for the Annual Meeting, was 22,431,154.
