as defendant. The federal complaints generally allege that the Registration Statement contains material omissions in violation of Section&#160;14(a) and Section&#160;20(a) of the Securities Exchange Act of 1934, as amended (the &#8220;Exchange Act&#8221;), and <span style="white-space:nowrap">Rule&#160;14a-9</span> promulgated thereunder, and the state complaint alleges state law claims of breach of fiduciary duty, aiding and abetting such breach of fiduciary duty, and fraudulent and negligent misrepresentation. The complaints seek various legal and equitable relief, generally including, among other things, orders (i)&#160;enjoining the defendants from proceeding with, consummating or closing the Proposed Transaction until the allegedly omitted information is disclosed, (ii)&#160;rescinding the Mergers if consummated, or awarding rescissory damages, (iii)&#160;directing the Umpqua board of directors and Columbia board of directors to file a corrected Joint Proxy Statement/Prospectus, and (iv)&#160;awarding plaintiffs&#8217; costs, including attorneys&#8217; fees. Columbia or Umpqua may be named in additional similar complaints. If such additional complaints are filed, absent new or different allegations that are material, Columbia and Umpqua will not necessarily announce such additional filings. Columbia and Umpqua believe that the claims asserted in the complaints are without merit and specifically deny that any supplemental disclosure was or is required under applicable law. However, in order to moot certain of the plaintiffs&#8217; disclosure claims in the complaints, to avoid nuisance, potential expense and delay, and to provide additional information to shareholders of Columbia and Umpqua, and without admitting any liability or wrongdoing, Columbia and Umpqua have determined to voluntarily supplement the Joint Proxy Statement/Prospectus with certain disclosures set forth herein.
