Item 1.01 Entry into a Material Definitive Agreement.

On July 22, 2011, MoSys, Inc. (the “Company”) entered into a Voting Agreement with Artis Capital Management, L.P. and several affiliated entities and a related individual (collectively, “Artis”).  Pursuant to the Voting Agreement, the Company has agreed to amend the Rights Agreement, dated November 10, 2010, between the Company and Wells Fargo Bank, N.A., as Rights Agent (the “Rights Agreement”) to provide that Artis will not be deemed to be an “Acquiring Person,” as defined under the Rights Agreement, as long as it beneficially owns less than 20% of the outstanding shares of common stock of the Company (in lieu of the 15% beneficial ownership limitation applicable generally to beneficial owners of the Company’s securities under the Rights Agreement) and otherwise remains in compliance with the Voting Agreement.

Pursuant to the Voting Agreement, Artis has agreed to vote any shares it beneficially owns from time to time in excess of the 14.99% threshold (the additional shares being referred to as “Voting Shares”) in accordance with the recommendations of the Company’s board of directors (the “Board”) at any meeting, and in any action by written consent, of the Company’s stockholders.  Artis also agreed to deliver proxies, duly executed by record holders of its beneficially owned shares, granting specified officers of the Company the authority to vote any and all Voting Shares in the event Artis fails to have them voted in accordance with the Voting Agreement.

In addition, Artis has agreed not to take, and not to permit its affiliates or associates to take, certain actions without Board consent as long as it beneficially owns any Voting Shares (except pursuant to a negotiated transaction approved by the Board), including, among others:

·                  acquisition of beneficial ownership of more than 19.99% of the Company’s outstanding securities;

·                  participation in a third-party tender offer or any merger, consolidation, business combination, liquidation or other similar transaction with respect to the Company;

·                  solicitation of proxies or consents with respect to any securities of the Company; and

·                  nomination of any person to the Board  or taking action otherwise to seek to control or influence the management, board of directors or policies of the Company.

Artis further agreed, during the term of the Voting Agreement, not to become a member of a group that engages in any of the actions listed above, and not to assist, induce or encourage, or enter into discussions or arrangements with, any third party with respect to any of the actions listed above.

The Voting Agreement will terminate automatically upon the termination of the Rights Agreement or at such earlier time as Artis certifies (or files a Schedule 13D or 13G evidencing) that it beneficially owns less than five percent of the Company’s outstanding securities.  In addition, the Company may terminate the Voting Agreement at any time following the breach of the Voting Agreement by Artis, subject to a 10-day cure period.

2

In connection with the Voting Agreement, on July 22, 2011, the Company entered into Amendment No. 1 to Rights Agreement (the “Amendment”) with the Rights Agent.  The Amendment provides that Artis shall be subject to a 20%, rather than 15%, limitation on beneficial ownership under the Rights Agreement, as described above.  The Amendment further provides that, in the event Artis breaches any provision of the Voting Agreement, then (unless the Board determines otherwise) the 20% limitation applicable to Artis will cease to apply, and Artis will instead be subject to the 15% limitation applicable generally to other beneficial owners of the Company’s securities (other than grandfathered stockholders).

The descriptions of the Voting Agreement and the Amendment under this Item 1.01 are qualified in their entirety by reference to the full text of the Voting Agreement and the Amendment, which are attached as Exhibits 10.19 and 4.2.3, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.
