<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Item&nbsp;8.01. Other Events.</B>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On January&nbsp;15, 2009, Harmonic Inc. (&#147;Harmonic&#148; or the &#147;Company&#148;) entered into a settlement
agreement (the &#147;Settlement Agreement&#148;) with Northrop Grumman Guidance and Electronics Company, Inc.
(&#147;Northrop Grumman&#148;), a company that was previously named Litton Systems, Inc. Pursuant to the
terms of the Settlement Agreement, Harmonic and Northrop Grumman agreed to settle litigation (the
&#147;Litigation&#148;) that resulted from the filing of a complaint by Northrop Grumman and Stanford
University (&#147;Stanford&#148;) in U.S. District Court for the Central District of California (the
&#147;District Court&#148;) alleging that optical fiber amplifiers incorporated into certain of Harmonic&#146;s
products infringe U.S. Patent No.&nbsp;4859016 (the &#147;Patent,&#148; and, together with any foreign
counterparts thereof, the &#147;Patents&#148;), which Patents are
held by Stanford and exclusively licensed to Northrop Grumman
pursuant to a license agreement. Northrop Grumman has the exclusive right, pursuant to the
license agreement with Stanford, to settle the Litigation.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Settlement Agreement provides, among other things, that, in exchange for a one-time lump sum
payment by Harmonic to Northrop Grumman of $5.0&nbsp;million, Northrop Grumman (i)&nbsp;would not bring suit
or otherwise assert against Harmonic or its affiliates, or any of its direct and indirect
customers, end-users, distributors, vendors, representatives, resellers or contract manufacturers,
any claim arising out of any of the Patents, and (ii)&nbsp;would release Harmonic, its affiliates,
customers, vendors, representatives, distributors, and its contract manufacturers from having any
liability for making, using, offering for sale, importing, and/or selling any Harmonic products
that may have incorporated technology that was alleged to have infringed on one or more of the
Patents.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Harmonic and Northrop Grumman have agreed to jointly seek entry of a stipulated judgment in the
District Court, or, alternatively, under certain specified circumstances, to enter into a
stipulation and order of dismissal.
