On August 25, 2010, DivX, Sonic, Merger Sub I and Merger Sub II entered into Amendment No. 1 to Agreement and Plan of Merger (the “Amendment”). The Amendment provides that “in-the-money” options to purchase shares of Common Stock of DivX that are held by individuals who will not continue as employees of Sonic following the closing of the First Merger will automatically be converted at the closing of the First Merger to the right to receive $3.75 in cash and 0.514 shares of Common Stock of Sonic, with cash paid in respect of fractional shares, for each share of Common Stock of DivX calculated to be issuable upon exercise of such stock option using the following formula:


		X =		Y (A-B)
				A


Where:	X =	the number of shares of Common Stock of DivX, rounded down to the nearest whole share, to be used for the purposes of determining the amount of cash and the number of shares of Common Stock of Sonic for which the stock option will be automatically converted at the closing of the First Merger;

	Y =	the maximum number of shares of Common Stock of DivX for which the stock option would be exercisable as of immediately prior to the closing of the First Merger without giving effect to any vesting or other restrictions applicable to the stock option;

	A =	$3.75 plus the product of (i) 0.514 and (ii) the closing price for a share of Common Stock of Sonic, rounded to the nearest one-tenth of a cent, as reported on Nasdaq for the trading day immediately prior to the closing of the First Merger; and

	B =	the exercise price of the stock option as of immediately prior to the closing of the First Merger.

The foregoing summary of certain terms of the Amendment does not purport to be complete, and is qualified in its entirety by reference to the Amendment, a copy of which is filed as Exhibit 2.1 hereto. The summary of the terms of the Amendment, as well as the text of the Amendment included in this Form 8-K, are intended to provide information regarding the material terms of the Amendment and are not intended to modify or supplement any factual disclosures about DivX or Sonic contained in their respective reports or statements filed with the SEC or other public information.
