Perot Systems Corp. (PER) shareholders have launched a bid to halt Dell Inc.'s (DELL) recent $3.9 billion bid for the IT services provider.

The suit, filed Monday in a Texas federal court, alleges Perot board members and other executives failed to maximize shareholder value and discouraged additional offers for the company before it reached its deal with Dell. The companies Dell and Perot, plus several Perot board members, are named defendants.

The suit seeks to halt the proposed deal until the companies "implement a procedure providing the best possible terms for shareholders."

"The proposed merger with Dell is the result of a hopelessly flawed process," Perot shareholders' attorney William Federman wrote in the lawsuit.

A Dell spokesman had no comment. A Perot spokesman couldn't be immediately reached for comment. Perot disclosed the lawsuit in a regulatory filing Thursday.

Dell announced the $3.9 billion deal on Sept. 21, and at the time was paying a big premium to catch-up with tech rivals expanding beyond their core businesses during the recession.

Dell has agreed to buy Perot for $30 per class A share- a 68% premium from the share's closing price on the Friday before the deal was announced.
