Based in Santiago, Chile, Certifica has offices throughout Latin America,
including Mexico, Brazil, Argentina, Colombia and Peru. The company was
founded in 2000 with the goal of becoming the leading analyst and auditor of
Internet traffic measurement and has won the endorsement of the IAB in several
Latin American countries to publish cross site statistics on Internet usage.
The sites measured by Certifica will be available for inclusion (on an opt-in
basis) in comScore's Media Metrix 360 hybrid measurement solution, which
combines panel-based audience measurement data and Web site analytics data to
provide a more comprehensive view of activity, beginning in early 2010. The
enhanced methodology will account for the full universe of Internet usage,
including traffic from Internet cafes and mobile devices.

Under the direction of Alejandro Fosk, founder and former CEO of Certifica and
now SVP and General Manager of comScore Latin America, comScore plans to sell
and service the full suite of comScore products in the region.

"We are very excited to be joining forces with Certifica. Alejandro and his
team have established a strong local presence, a high quality portfolio of
services, and an excellent reputation for client service," said Linda Abraham,
comScore CMO and EVP of Global Product Management. "Latin America currently
represents 9 percent of the world's population, and although the Internet
penetration there is relatively low compared to some other parts of the world,
it is growing at a rapid pace, presenting growth opportunities for many
advertisers and publishers. With 57 percent of the population under the age of
25, Latin America also owns the title of 'the youngest continent' and
represents a sophisticated, engaged and connected Internet user base. This
acquisition will strengthen our presence in the region and enable us to offer
hybrid measurement as part of our Media Metrix 360 initiative using the same
state-of-the-art measurement technologies we use elsewhere in the world. We
warmly welcome our Certifica colleagues into the comScore team."

"comScore is an ideal partner to leverage Certifica's existing expertise in
Latin America and provide the market with a more comprehensive digital
measurement platform that will promote the growth of the online advertising
market," said Alejandro Fosk, founder and former CEO of Certifica. "We are
excited that Certifica's clients will have access to comScore's robust
reporting platform, which will enable them to understand the complete digital
landscape and lead to new ways to optimize their digital marketing
strategies."

comScore does not expect the acquisition to have a material impact on 2009
financial results.

Latin America Digital Media Industry Voices Support for Acquisition
"At a moment where the Latin American market is experiencing an inflection
point far beyond other markets of the world, we are very pleased to see the
entrance of comScore sided with a local player such as Certifica. Terra has a
local presence in 18 markets in Latam and US Hispanics and understands the
importance of 'glocal'," said Paulo Castro General Manager of Terra Brazil and
former Chairman of IAB Brazil.

"The union of Certifica and comScore is certainly a positive development for
the Latin American digital marketplace," said Nicolas Berman, Marketing
Director of MercadoLibre. "Bringing together these leading companies to
provide Latin America with a unified digital measurement capability will give
the industry the comprehensive view of consumer behavior that will facilitate
the allocation of marketing and advertising budgets online."

"The comScore-Certifica merger represents a natural fit in bringing together
leaders in panel-based audience measurement data and website analytics data,"
said Rodrigo Donoso, Head of Digital Media at El Mercurio Publishing Group,
part of GDA. "Their combined offering will give the Latin American marketplace
the premier digital measurement platform that will bring us closer to having a
true measurement currency in the market."

"I believe that this alliance represents a big progress for Latin America´s
digital industry. For the development of the online advertisement market, it
is fundamental to rely on trusted metrics that will allow us to prove our
clients the effectiveness of their campaigns, and this is what Certifica and
comscore are bringing to the market with this alliance," said Fernando Campos,
General Director of New Media at TV Azteca.
