UPDATE 11-Knight Capital gets $400 million rescue, shares tumble

* Investors get 70 percent-plus in company

* Analyst says company likely to be broken up

* CEO: Too soon to say if firm will shrink

* Shares tumble 24 percent

NEW YORK, Aug 6 (Reuters) - A group of investors rescued

Knight Capital Group Inc in a $400 million deal that

keeps the embattled leader in U.S. equities market-making in

business, but comes at a huge cost to existing shareholders.

Chief Executive Tom "TJ" Joyce told Reuters the new

investors support him and his management team, but it was too

early to tell whether the firm would shrink or keep the same

strategy it had before last week's losses.

There were immediate signs the Jefferies Group -led

rescue gave Knight back some of the market confidence it had

lost, as two large brokerages resumed routing orders through the

company and new data showed volumes picking up from last week.

Blackstone Group LP, rival market maker Getco and

financial services companies TD Ameritrade Holding Corp

, Stifel Nicolaus, Jefferies and Stephens Inc

purchased preferred shares for what works out to be a 73 percent

stake in the company, Knight said.

Knight has been the largest U.S. provider of retail

market-making in New York Stock Exchange and Nasdaq-listed

stocks, buying and selling shares for clients. As a market maker

it also provides liquidity to equity markets by stepping in to

buy and sell stocks, using its own capital to ensure orderly

activity.

Knight shares closed down 24.2 percent at $3.07. Those who

held Knight shares before Monday will feel the pain of the

company's rescue the most acutely. The massive dilution that

accompanies the deal means their stakes are worth just a

fraction of what they were days ago.

Roger Freeman, analyst at Barclays, said the dilution due to

the new investment would imply Knight's value is about $1 a

share. He has a $3 price target on the stock, but said it was

too early to estimate how earnings would be affected in 2013.

Yet Knight co-founder Kenneth Pasternak told Reuters he had

no regrets about accumulating hundreds of thousands of shares in

the company since last week's disaster emerged, despite having

lost money as a result of Knight's rescue. He retired from

Knight in 2002.

BREAKUP COMING?

The rescuing companies will buy preferred stock convertible

at $1.50 each with a 2 percent dividend to save Knight, which

was left reeling last week by a software glitch that caused

errant trading in dozens of stocks. Knight lost money by

selling shares it had inadvertently bought during the day.

The preferred shares are convertible into about 267 million

common shares, Knight said in a U.S. Securities and Exchange

Commission filing.

Jefferies CEO Richard Handler and executive committee

chairman Brian Friedman reached out to Knight on Wednesday, the

day of the trading snafu, to offer their services, one source

directly familiar with the matter said. The person was not

authorized to discuss the issue publicly.

Sandler O'Neill had been tapped by Knight to advise on a

deal. But by Friday Jefferies was circulating a term sheet to

potential investors based on the same deal format that was later

announced on Monday, sources said. Jefferies backed the deal by

making a principal investment itself.

Unlike many private equity firms that snubbed an approach by

Knight, Blackstone took an active interest as it was exploring a

buyout of the firm. But Blackstone was told to either join the

investor group or walk away, according to one of the sources.

"As a financial investment, Knight is a very valuable firm,

but it needed liquidity and if it didn't have liquidity, a lot

of that value was going to go away," Getco CEO Daniel Coleman

told Reuters in an interview. "So we thought it was a pretty

good bet that by providing liquidity we could preserve that

value and perhaps increase it."

Getco, nominally a Knight rival, gets a strategic advantage

via the deal as well -- an inside peek at a bigger rival that

has some lines of business Getco does not.

Stephens Inc Chief Operating Officer Curt Bradbury, in an

interview, said he was long-time friends with Joyce and that his

firm approached Knight in that vein on Friday. He said that

while there may have been some negotiations by others on terms,

Stephens was fine with the term sheet as it was presented.

As part of the deal, the investor group will take three

board seats. In a regulatory filing, Knight said Blackstone and

Getco parent General Atlantic would each fill one seat, while

the board will propose a third member acceptable to Jefferies.

Each retains those rights as long as they hold at least 25

percent of the preferred shares they purchased in the deal.

JP Morgan analyst Kenneth Worthington, in a client note

after the initial reports of the rescue on Sunday night, said

the deal presaged Knight's eventual breakup.

Worthington cited two Knight businesses, the reverse

mortgage lender Urban Financial and foreign exchange platform

Hotspot FX, as assets that could draw interest, but Joyce said

it was too soon to say what would happen to the firm's assets.

"Right now we kind of like our footprint and we will

continue to execute on the strategy we had before the error took

place, but as we kind of get back to business and do our annual

budgeting and strategic reviews at the end of the year, that

will be something that we will have to address," he said.

FUTURE STILL UNCERTAIN

Vanguard Group, one customer that pulled orders from Knight

last week, said Monday it was again routing there, as did

E*Trade Financial Corp.

But even if Knight has been saved for now, the company could

face litigation from shareholders.

The potential liability could increase if it were found that

Knight violated market rules. The SEC, the top U.S. securities

regulator, said on Friday that government lawyers were trying to

determine whether Knight violated a new rule designed to protect

the markets from rogue algorithmic computer trading programs.

According to those people familiar with the matter, U.S.

Securities and Exchange Commission Chairman Mary Schapiro spoke

with Joyce last Wednesday afternoon from her vacation spot in

Maine. Joyce brought up rules on erroneous trades during the

call and expressed hope for some flexibility. But Schapiro did

not convey a view on it during the call, the sources said.

Knight's problems started early Wednesday, when a software

glitch flooded the NYSE with unintended orders for dozens of

stocks. That boosted some shares by more than 100 percent and

left the company holding the shares, causing the trading loss.

DAMAGE SWIFT

The damage to Knight was swift. Whereas Knight once

accounted for 20 percent of the market-making activity in shares

of Apple Inc, by midday Friday it was the market maker

for 2 percent of the volume, according to Thomson Reuters AutEx.

But on Monday, AutEx data showed, that volume was back up to

19.4 percent, and it was on the rise for other stocks as well.

Barclays Capital's Freeman, in a note Monday, said he

assumed that Knight's overall volumes in 2013 would be about 15

percent below where they were in the second quarter of 2012.

Sandler O'Neill + Partners and Wachtell, Lipton, Rosen &

Katz advised Knight Capital on the bailout. Barclays Plc

advised TD Ameritrade on its investment.
