Cash increased during the quarter to $15.1 million at January 31, 2007 from $14.7 million at October 31, 2006.

“Although we continued to experience sluggish license revenue during the quarter as more complex sales initiatives lengthened the overall sales cycles with larger customers, we are increasingly pleased with the progress we are making in these initiatives,” said Philip Deck, CEO of MKS. “We have made major investments in large account sales, packaged applications integrations and Asian expansion over the past few quarters and expect to see much stronger license revenue as a result in the near future.”

“This past quarter brought further progress with deployments of MKS Integrity in our traditional accounts where our expanding breadth of use continues to make MKS Integrity more mission critical to their operations” said Michael Harris, MKS President and COO. “Our investments in large account penetration represent a critical transition to a new level of enterprise sales for MKS – a transition that is time consuming and expensive but essential in creating market share among the most demanding customers in the world.”

Total revenue for the third quarter of fiscal 2007 was $11.6 million, down from $13.4 million in the third quarter of fiscal 2006. Net loss for the third quarter of fiscal 2007 was $(1.2) million, or $(0.02) per share, compared to net income of $1.6 million or $0.04 per share in the third quarter of fiscal 2006. Third quarter fiscal 2007 application lifecycle management (ALM) revenues were $9.8 million, compared with $11.6 million in the third quarter of fiscal 2006.

For the nine months ended January 31, 2007 total revenue remained relatively unchanged at $35.7 million compared with the nine months ended January 31, 2006 with a decrease in license revenue of 19 percent and increases in maintenance and service revenue of 18 percent and 22 percent, respectively. Net income for the nine moths ended January 31, 2007 decreased to ($2.4) million from $3.1 million for the same period in the prior fiscal year.

Outlook for Fiscal 2007
The Company believes that annual revenue for fiscal 2007 will be in the range of $50 to $52 million and income before tax will be in the range of ($1) to $1 million, revised down from the guidance given last quarter. The material factors and assumptions applied by the Company in arriving at these ranges and that could materially affect the Company’s liquidity are: the ability of the Company to successfully expand its ALM sales, services and research and development staff and to generate higher revenue in the ALM segment; the ability of the Company to make increased marketing expenditures in the ALM segment; increased ALM research and development expenditures to ensure the Company maintains its technical leadership in the ALM market; the Company will incur increased costs relating to stock compensation charges; and the expectation that the Company's Interoperability business will decline on an annual basis of approximately 10 percent over the course of the year.

Income tax expense is recorded in the Company’s financial statements at the prevailing tax rate in the jurisdiction where the income was generated, to the extent a deferred tax asset has been recorded in that jurisdiction. Such rate may be higher than the average rate the Company expects to pay in the future across all jurisdictions. The Company expects the long term tax rate to be approximately 35 percent to 36 percent. This will be subject to an ongoing quarterly assessment of the valuation allowance by jurisdiction which may give rise to further increases or decreases to the existing tax asset.

The Company will hold a conference call at 5:00 p.m. EST to discuss its third quarter performance. Interested parties may access the call by dialing 877-871-9526 or 416-620-2400.
