Talks with Chipzilla broke down over the price, which Alteria management felt was too low. Cadian
Capital Management and TIG Advisors, have told Alteria to stop mucking about and talk turkey with Chipzilla.

In letters to Altera's management, shareholders have raised concerns about the company's ability to create value on its own that matches Intel's offer, Bloomberg reported.

The company has agreed to resume takeover talks with Intel.

Some other large investors also have also sent letters, two people familiar with the matter told Bloomberg.

Intel's offered $50 per share range while Altera's shares are currently worth $43.86 and valued at $13.2 billion. The stock has surged nearly 27 percent since merger talks was first reported by the Wall Street Journal in March.

Cadian was Altera's 10th-largest shareholder, with a 2.77 percent stake. TIG owns about 1.5 percent of Altera's outstanding shares, one of the people told Bloomberg.  It looks like what will  be Intel's biggest buy out is back on again.
