The deal will likely close in the second quarter. Shares were climbing $2.16, or 18%, to $14.16.

EGL ( EAGL) stock deflated to pre-January levels after the Houston-based freight company warned of weak fourth-quarter numbers, prompting private equity firm General Atlantic to drop its support for a buyout bid proposed last month. Chief Executive James Crane, EGL's main shareholder, had led the $36-a-share offer. Shares were losing $6.36, or 16.8%, to $31.53.

Aspect Medical Systems ( ASPM) fell after the Newton, Mass., company projected non-GAAP earnings of between 6 cents and 8 cents a share in the first quarter, which would widely miss the Street's 16-cent per-share estimates.
