3i Leads Round with $97 Million; VantagePoint Venture Partners
Adds to Existing Investment
BEDMINSTER, N.J.--(Business Wire)--GAIN Capital Group, LLC, a market leader in the rapidly growing
online foreign exchange (FX) industry, today announced the successful
completion of an investment round from two leading private equity
firms with a specialty focus in finance and technology. 3i led the
round with a $97 million investment, while existing investor
VantagePoint Venture Partners participated with a $20 million
investment. In connection with the investment, 3i US Growth Capital
Partner Whitney Bower will join GAIN's Board of Directors.

3i and VantagePoint purchased a minority stake from existing
shareholders of the privately-held GAIN Capital, with a portion of the
proceeds going to the company's balance sheet to facilitate larger
trading relationships with leveraged funds and institutions globally,
as well as to support GAIN's growing white label business.

"We are pleased to welcome 3i to our investor group," stated Glenn
Stevens, GAIN's chief executive officer. "We will undoubtedly look to
leverage 3i's financial expertise, strong global network and
recognized ability to add value to help us achieve our long term
business goals."

"We are excited to partner with GAIN Capital," commented Whitney
Bower, Partner at 3i US Growth Capital. "GAIN has a strong reputation
and an impressive track record from a financial perspective, achieving
no less than 65% annual growth for the past six consecutive years,"
continued Bower. "We look forward to helping GAIN accelerate the
success of its business development initiatives and further strengthen
its operations in key international markets."

Forex is the most traded market in the world, with a daily volume
that exceeds $3.2 trillion, according to the Bank of International
Settlements (BIS). Among retail investors, forex trading has gained
widespread acceptance over the past several years. According to U.S.
research firm Aite Group, average daily trade volume in the retail
forex market increased 500% from 2001 to 2006, reaching an estimated
$77 billion per day in 2007.*

"VantagePoint's decision to make the follow-on investment is a
testament to GAIN's management team and the company's prospects,"
commented Jim Mills, a managing director at VantagePoint Venture
Partners and a member of GAIN's Board of Directors. "We are confident
that GAIN is well positioned to take full advantage of the significant
market opportunities within this space." VantagePoint was the sole
investor in the company's previous investment round completed in
April, 2006.

In addition to 3i and VantagePoint, GAIN's investor group also
includes private equity firms Tudor Ventures, Edison Venture Fund,
Cross Atlantic Capital Partners, and Blue Rock Capital.
