Vector Capital to Acquire Printronix for $108 Million in Cash

IRVINE, Calif. and SAN FRANCISCO —(BUSINESS WIRE)—October 2, 2007—Printronix, Inc. (Nasdaq: PTNX), a leading manufacturer of integrated enterprise printing solutions for the supply chain, today announced that it has signed a definitive agreement to be acquired by Vector Capital, a San Francisco-based private equity boutique specializing in buyouts, spinouts, and recapitalizations of established technology businesses.

Under the terms of the agreement, Printronix stockholders will receive $16.00 in cash for each share of Printronix common stock, representing a total price of $108 million. This represents an approximately 18.3% premium over the closing price of Printronix shares on October 1, 2007. The Board of Directors of Printronix, acting on the unanimous recommendation of a Special Committee of independent directors, has approved the merger agreement and recommends that Printronix stockholders support the transaction. This agreement represents the culmination of a process by Printronix, with the advice and assistance of Houlihan Lokey Howard & Zukin Capital, Inc., to solicit interest in a potential acquisition of Printronix.

Robert Kleist, President and CEO and largest shareholder of Printronix, and the current executive management team of Printronix will remain in their current positions with the Company.

“We believe this transaction delivers outstanding value for our stockholders, and better positions the Company to succeed in the global printer market,” said Mr. Kleist. “Following a comprehensive review, our Board of Directors concluded this transaction is in the best interests of our Company and our stockholders. Our management team remains committed to maintaining our relationships with our customers, suppliers and channel partners.”

“The acquisition of Printronix during this volatile time in the financial markets exemplifies Vector’s expertise in helping businesses navigate through complex situations,” said Amish Mehta, partner at Vector Capital. “Printronix is a leader in line-matrix and thermal printing solutions for growing enterprises around the world. With the backing of Vector Capital and the benefits of being a private company, Printronix will now be able to maintain its sole focus on day to day business operations, innovation, and delivering excellent products and service to the market.”

Mr. Kleist and other members of senior management are expected to own approximately 9.9% of the Company after consummation of the transaction.

The closing of this transaction is subject to various conditions, including the approval by holders of a majority of Printronix’s outstanding common stock.

Houlihan Lokey is acting as financial advisor to the Special Committee of the Board of Directors of Printronix. Stradling Yocca Carlson & Rauth is acting as legal advisor to the Special Committee. O’Melveny & Myers LLP is acting as legal advisor to Vector Capital.
