Cytori Therapeutics (San Diego) received a second $6 million payment from Green Hospital Supply (Tokyo) in exchange for 1 million shares of Cytori common stock.

Cytori received the first $6 million payment on Feb. 29, and issued 1 million shares to Green at that time. Under the equity agreement, Green also was granted a non-voting observer seat on Cytori's board.

Align Technology (Santa Clara, California) reported that its board has authorized a stock repurchase program of up to $50 million, effective immediately.

"Returning this excess cash to our shareholders through a repurchase program will contribute to our goal of enhancing shareholder value. It will also have the effect of offsetting dilution from our employee equity plans," said Ken Arola, VP and CFO of Align.

The program does not obligate Align to acquire any particular amount of common stock and depending on market conditions and other factors, these purchases may be commenced or suspended at any time, or from time-to-time without prior notice.

As of April 25, Align had about 69.6 million shares outstanding.
