HP Completes Acquisition of ArcSight


Company takes new approach to help customers secure applications and services from build through deployment

PALO ALTO, Calif., Oct. 22, 2010 - HP today announced that it has completed the
acquisition of ArcSight, a leading security and compliance management company,
for $43.50 per share, or an enterprise value of $1.5 billion.

Integrating ArcSight's security portfolio with HP's IT operations management
portfolio will allow organizations to converge millions of events across IT operations
and security, providing deeper context than either platform alone. This represents a
new security approach that will help businesses understand risk by making visible
everything from activity to configuration state, role rights and past history.

By aligning IT assets with business objectives, chief information officers will have a
common context and consolidated view of all IT risk and compliance issues for
business services and applications. Customers will be able to monitor real-time
events and activities, assess the risk and impact to their business operations, and
quickly respond to and correct potential threats.

Further details on the ArcSight product integration into the HP Software and
Solutions portfolio as HP expands into the security information event management
(SIEM) market will be announced at a later date.

Upon the closing of the acquisition, all remaining outstanding shares of ArcSight
common stock, other than those held by stockholders who properly perfect
appraisal rights under Delaware law, were converted into the right to receive
$43.50 per share in cash. As a result of the transaction, ArcSight has become a
subsidiary of HP.
