Hewlett-Packard Co. said Monday that general counsel Michael Holston will leave the company to pursue other opportunities. It is the latest personnel move since Meg Whitman took control of the struggling technology company in September.

The company said David Healy, co-chair of the mergers and acquisitions group of Fenwick & West LLP, will act as HP's general counsel on an interim basis. Healy represented HP in its acquisition this year of business analytics company Vertica, and in its agreement to sell its video collaboration business unit to Polycom.

HP said a formal search is underway for Holston's permanent replacement. It is considering candidates inside and outside the company.

Whitman became CEO of HP after the firing of Leo Apotheker, who made such radical moves as saying the company would spin off its personal computer unit, a move that Whitman has since reversed.

The company also said last week that it would make its webOS mobile operating system software available as open-source code for developers to modify. The future of webOS was in question after Apotheker said HP would stop making tablet computers and smartphones.

HP shares closed down 44 cents, or 1.6 percent, at $27.34 on Monday amid a broad market downturn on concerns about Europe's latest plan to fix its debt problems.
