Zix Corporation CEO Provides Corporate Update for Q3 2007

ZixCorp exceeds cash guidance as the Company also achieves new quarterly revenue record

DALLAS — October 3, 2007 —Zix Corporation (ZixCorp^®), (Nasdaq: ZIXI), the leader in hosted services for email encryption and e-prescribing, today offered a corporate update by its chief executive officer, Rick Spurr.

“We had a good quarter in each of our core businesses — Email Encryption and e-Prescribing,” said Spurr. “Preliminary revenue estimates are that we will again meet or slightly exceed our guidance range ($5.7 to $6.0 million). In our Email Encryption business, where orders in the second half of the year have historically lagged behind the first half, we had the highest Q3 new first-year orders in the Company’s history with an estimated $1.3 million and estimated total orders of $5.4 million. Demand remained strong for our service model in both healthcare and financial services, and we had continued high customer satisfaction as evidenced by strong renewals.”

Of the company’s e-prescribing business, Spurr said, “Our PocketScript business maintained a solid performance. We exceeded the high end of the 450-500 e-prescribing deployment guidance for the quarter and ZixCorp marked a milestone in the third quarter announcing that it had processed more than 14 million e-scripts to date. Script volume continues to grow with the Company closing the month of September with a record 155,000 e-scripts over a one-week period. PocketScript customers remain highly satisfied and, of course, we added our eighth payor sponsor during the third quarter.”

“ZixCorp continues to perform ahead of plan for 2007 with respect to our net cash consumption,” continued Spurr. “I am very pleased that we were able to maintain the strong results we delivered in the first half of 2007. Our third quarter ending cash balance of $11.5 million, including $1.7 million in restricted cash, was well ahead of our guidance range of $11.0 to $11.3 million. The cash burn for the third quarter 2007 was $600,000, compared with a $4.7 million burn for the third quarter of last year, driven by both greater than anticipated cash receipts from our Email Encryption business and reductions in overall spending. We remain on track to burn less than $4.3 million for all of 2007 and to attain our goal of achieving positive cash flow in Q1 of 2008.”
