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

On January 14, 2013, the Board of Directors (the "Board") of the Company approved the Amendments, effective immediately. The Amendments include, among other things, the following changes:

Х The Amendments establish specific procedures relating to a special meeting requested by stockholders. Specifically, the Board is empowered to fix the date, time, place and record date for a requested special meeting. Furthermore, the Amendments provide that a special meeting shall not be held in circumstances where the business has been addressed or will be addressed at an annual or other special meeting occurring within a certain time before or after the request is made.

Х The presiding officer has the power to adjourn any meeting of stockholders at which a quorum is not present or represented.

Х The Bylaws now provide that all actions required or permitted to be taken by stockholders must be taken at a duly held meeting at which a quorum is present. Previously, stockholders were permitted to act by written consent in lieu of a meeting.

Х In order for stockholder proposals and director nominations to be properly brought before an annual meeting, notice of such proposals or director nominations must be received by the secretary of the Company not later than the close of business on the 90thday, nor earlier than the close of business on the 120th day in advance of the anniversary of the previous year's annual meeting (other than with respect to any annual meeting held prior to June 30, 2013, notice for which must be received not later than the close of business on the 60th day following the first public disclosure of the Amendments). The notice must include specified information about the proposing stockholder (and, if made on behalf of a beneficial owner, about such beneficial owner), the director nominee (if applicable), beneficial ownership of Company securities (including derivatives and other hedging arrangements) and certain voting and other arrangements. Stockholders eligible to vote at any special meeting called to elect a director or directors may nominate a director or directors for election if (i) they deliver a notice meeting the same content requirements as for an annual meeting and (ii) such notice is delivered not later than the close of business on the 90th day prior to such special meeting and not earlier than the close of business on the later of the 120th day prior to such special meeting or the tenth day following the first public disclosure of the date of the special meeting.

The foregoing description of the Amendments is qualified in its entirety by reference to the complete text of the Amendments, a copy of which is filed as Exhibit 3.1 to this Current Report on Form 8-K and incorporated by reference herein.
