Private equity investors are using current financial market constraints on liquidity to negotiate favorable deals, as private equity general partners have watched the values of their portfolios fall profoundly. Efforts to attract additional investment haven't been easy, as potential limited partners are reluctant to make long commitments in an uncertain marketplace. This has given limited partners a stronger position from which to negotiate both fees and terms and conditions.

Limited partners are getting a leg up on the private equity funds in which they invest, signaling a change from the historical trend in which funds could push for aggressive compensation based on the returns they provide. In a poll conducted by Preqin, 43% of investors noted a power shift from fund to limited partner, with only 2% seeing a shift toward the general partner.

Tobacco titan Philip Morris International Inc. (NYSE: PM) is snapping up the South African operations of Swedish Match for a cool 1.75 billion rand, or roughly $224.7 million. The acquisition is part of PM's broader strategy to gain a foothold in the smokeless tobacco arena. Currently, Swedish Match South Africa is the market leader in the South African pipe tobacco and snuff categories.

"This financially attractive acquisition represents an excellent strategic fit for our business in South Africa," said Jean-Claude Kunz, PM's president of Eastern Europe, Middle East, and Africa. "We firmly believe that merging the two businesses will provide us with the talent, infrastructure, and expertise to further build and grow our portfolio of strong brands in this important market."

The venture capital (VC) industry demonstrated its commitment to the clean technology space in the second quarter of 2009, pumping $1.2 billion into the sector, according to a report by GTM Research. VC investments in cleantech are up 43.5% from the first quarter of the year, when $836 was put into play in the cleantech space.

The number of transactions increased, as well. In the first quarter, 59 deals were completed, and deal-flow surged 44% to 85 in the quarter just finished. Average deal size remained fairly consistent: $14.2 million for the first quarter and $14.1 for the second.

Dan Duncan, who is a billionaire, understands the importance of patience (especially in creating lots of wealth). An example of this is his latest deal; that is, his company, Enterprise Products Partners LP (NYSE: EPD), has been pursuing Teppco Partners LP (NYSE: TPP) since March. At that time, Duncan offered about $2.8 billion for the company. And yes, according to the senior management at Teppco, it was too low.

Well, after some wrangling, there is now a deal. Of course, the price tag is higher -- at $3.3 billion (it's a stock-for-stock swap).

Are we seeing the return of "merger Monday"? Well, today there is a big deal: Towers, Perrin, Forster & Crosby Inc. and Watson Wyatt Worldwide Inc. (NYSE: WW) have agreed to a $3.5 billion merger (the equity will be split 50-50). The new entity will be called Towers Watson & Co.

These companies are major operators in the benefits-consulting space, which has been under pressure during the recession. So, why not strengthen things with a tie-up?

Microsoft (NASDAQ: MSFT) has engaged investment bank Morgan Stanley (NYSE: MS) to help it unload digital agency Razorfish. Publicis (OTC: PGPEF) is looking for targets in the online ad space and could be a possible bidder.

Razorfish has been valued at $600 million to $700 million, based on a top line of approximately $400 million for its last fiscal year and peer margins of 12% to 13%. The company boasts 2,000 employees and clients that include Audi, Nike (NYSE: NKE) and Kraft (NYSE: KFT). Microsoft bought the company as part of a $6 billion deal to acquire aQuantive. At the time, Razorfish was known as Avenue A Razorfish, as the result of a merger sealed in the wasteland known as the "dotcom bust."

Republic Airways Holding Inc. (NASDAQ: RJET) is going shopping. Only a day after making an offer for ailing Frontier Airlines (OTC: FRNTQ), it has made a bid to nab Midwest Airlines from private equity firm TPG Capital. The offer consists of $6 million in cash and a note for another $25 million. If the private equity house takes the deal, Republic will get 100% of Midwest's equity and TPG's secured note of $31 million.

The $25 million in debt is convertible to RJET stock at $10 a share, which gives TPG a bit more upside from the transaction. The seller would also have the right to nominate a member of the buyer's board of directors.

Of course, Republic's CEO, Bryan Bedford, is upbeat about the prospect of buying Midwest Airways, saying it will "enhance the strategic positioning" of his company. Like the proposed acquisition of Frontier, Midwest would continue to operate under its own name, though the target's Boeing 717s would be replaced with Embraer 190s.

Sina (NASDAQ: SINA - option chain) shares are rising today after the company was upgraded by Deutsche Bank from Sell to Hold with a price target of $31. This action comes even though Deutsche thinks that Sina's deal for Focus Media Holdings (NASDAQ: FMCN) is getting more likely to fall through. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on SINA.

SINA opened this morning at $30.22. So far today the stock has hit a low of $30.09 and a high of $32.60. As of 11:35, SINA is trading at $32.42 up $2.42 (8.1%). The chart for SINA looks bullish.

While Twitter's founders are struggling to figure out exactly how to cash in on their creation, others may have found a way.

Lolplaying, a gaming company, seems to have found a new way to make some cash with their new role-playing game called 140Mafia (a reference to how many characters you use to tweet). The company is trying to harness Twitter's ability to make money by teaming with Super Rewards, which is a "virtual currency" service that makes a great deal of cash from various forms of online recreation.

Rumor has it that Nortel Networks (OTC: NRTLQ) will sell its enterprise division in the near future.

This would be part of a broader plan to break the company apart instead of trying to restructure its way out of bankruptcy. The company is planning to sell its CDMA and LTE wireless businesses to Nokia (NYSE: NOK) for $650 million -- the first unit sale since the January bankruptcy filing.

TheStreet.com's Jim Cramer wants to out the bankers behind the Red Roof deal and other deals like it.

What didn't they take private? What didn't they lever up? When I read about Extended Stay's bankruptcy and Red Roof's default Tuesday night I started thinking, did anyone besides me ever stay at places like this? Did anyone ever realize the marginality of these places? Did they simply look at some numbers on some pieces of paper and say, "Yep, that's money in the bank"?

And sure enough, Citigroup (NYSE: C) (Cramer's Take) was the lender to Red Roof, a deal two years old that has already gone sour. Maybe this was one of those have-to-keep-dancing-until-the-music-stops deals by Chuck Prince, the foremost clown of all of the bankers of the era.

The $52 billion merger of Anheuser-Busch InBev has resulted in some nice opportunities for private equity firms. For example, KKR recently purchased a division of the firm -- Oriental Brewery Co. (the number two brewer in South Korea) -- for $1.8 billion.

Doesn't sound like a lot? Well, it is a big deal. In fact, it's the biggest private equity deal in nine months.

While M&A activity has been mostly lackluster, this has not been the case in the pharma industry. The major players are trying to reposition themselves for changes in regulations, as well as patent expirations of mega drugs.

So, today we got another deal: Watson Pharmaceuticals (NYSE: WPI) agreed to purchase Arrow Group for $1.75 billion. The transaction will be paid in cash and stock.

Activist investor Carl Icahn is reportedly interested in taking another run at Delphi Corp. after a federal judge ordered the bankrupt auto parts supplier to open the sale of its assets to potential bidders, in addition to the previous offer from private-equity firm Platinum Equity.

Icahn's auto-parts company, Federal-Mogul Corp. (NASDAQ: FDML), had held discussions with Delphi, but the Presidential Task Force on the Auto Industry, which was set up by the Obama administration to oversee the restructuring of the U.S. auto industry, preferred the Platinum Equity deal.

Last week was a busy one for San Francisco-based private equity firm Golden Gate Capital. It not only reached an agreement to acquire the assets of the J. Jill Group Inc. from Talbots Inc. (NYSE: TLB), but also reached a deal in the sale of SoftBrands Inc., a Minneapolis-based software producer.

Jill Acquisition LLC, an affiliate of Golden Gate, agreed to purchase the womenswear retailer for approximately $75 million. The deal includes assets and liabilities, including a distribution center in New Hampshire, and intellectual property and inventory. Jill Acquisition assumes the leases of 204 J. Jill stores, with the remaining 75 expected to be closed by Talbots. Talbots' board unanimously approved the deal, and the transaction is expected to be completed in the second quarter.
