NEW YORK ( StreetAuthority) -- With a rising economy comes rising expectations. CEOs at mid-sized and large companies need to find new paths to growth to justify -- or boost -- their company's stock price. That's no mean feat in an economy still in slow-growth mode. As a result, expect to hear about plenty more deal-making in 2011 as smaller companies get acquired to help jumpstart the top line.

To be sure, acquiring companies don't want to buy a company many years from generating its own action. Instead, they want companies that have already done a lot of heavy lifting, developing new products and the marketing plans to support them.

I've identified four small companies that are truly ripe for a deal. Investors should take a close look at these firms.

1. Savient Pharma (SVNT)

This company has been practically begging "buy me." After receiving Food and Drug Administration approval for a new and highly-effective drug for the treatment of gout, the company declared it had no intention of remaining solo. Speculation that a major pharmaceutical company such as Bristol-Myers Squibb ( BMY) or Pfizer ( PFE) would snap up Savient pushed its stock up north of $20 last September. When the company admitted it couldn't find a taker, shares plunged and are now below $10.

Since then, Savient has decided to build a sales force and will start to generate its own sales until a buyer emerges. Sales began in the fourth quarter of 2010 and are expected to hit $10 million per quarter by the third quarter of 2011. Just this week, Savient received a significant endorsement when the Department of Veterans Affairs signed up for a five-year purchase agreement. (It is estimated that one in seven gout sufferers is a U.S. veteran.)

The VA deal may be the catalyst that brings potential suitors back to the table. Savient could secure $40 million in revenue this year and perhaps double that in 2012. Analysts at Global Hunter Securities predict annual sales may eventually top $500 million. Those are the kinds of numbers that get the attention of Big Pharma. With or without a buyout, this stock looks quite undervalued. A buyout would simply help the stock to arrive at its destination much faster.

2. Biolase Technologies (BLTI)

I profiled this company two months ago and shares have risen 175% since then. That may not be the end of it. Shares may surge yet higher if takeover rumors are to be believed.
