NEW YORK ( TheStreet) -- Several stocks trading near $5 were poised to move on above-average volume during Monday's session.

The new convertible note bears a rate of 7.95% and matures in March 2015. The initial conversion price of the principal and any accrued but unpaid interest on the convertible note is $2.08 per share.

Nile Therapeutics ( NLTX) slid by 8 cents, or 9.1%, to 80 cents in Tuesday's after-market session after the company said it intends to offer units consisting of shares of its common stock and warrants to purchase shares of its common stock in a public offering.

Hansen said it shipped seven of its Sensei Robotic Catheter Systems in the later part of the quarter, but those will not be accounted for in the first quarter due to revenue recognition policies.
