1 Exhibit 5.1 to Aspen Technology, Inc. 8K filed May 10, 1999 Aspen Technology Reports 1999 Third Quarter Results Announces Restructuring Program Intended to Reduce Costs, Improve Productivity Cambridge, MA - April 27, 1999 -- Aspen Technology, Inc. (NASDAQ: AZPN), the leading supplier of enterprise manufacturing optimization solutions for the process industries, today reported results for its third quarter ended March 31, 1999. Based on these results and continuing economic pressures on customers in the refining, chemicals and petrochemicals sectors, the Company announced it has implemented a restructuring program intended to reduce AspenTech's operating costs and improve productivity. The Company reported total revenues of $54.2 million in the third quarter of fiscal 1999, compared with $68.4 million in the same period last year. For the three months ended March 31, 1999, software license revenue was $22.2 million, while services revenue totaled $32.0 million. Net loss for the third quarter totaled $5.9 million or $0.23 per share, compared with net income of $9.3 million or $0.37 per share, excluding one-time charges, for the same period in fiscal 1998. During the third quarter, AspenTech closed a number of software license agreements. The Company's supply chain business performed well, closing significant transactions in the quarter for its Aspen MIMI product with a major European specialty chemicals company and with one of the largest aluminum recyclers in the world. The Company sold the largest Aspen PIMS license in the company's history to Equiva, the services group for Motiva and Equilon (the new refining joint ventures from Texaco, Shell and Star). AspenTech also won a major integrated Plantelligence automation project for an ethylene complex in North America to be operated by the BASF Fina joint venture. Additional transactions signed during the third quarter included license agreements with Aristech Chemical, Consolidated Paper, Dow Chemical, Hoechst and Union Carbide. "Difficult economic conditions in the refining, chemicals and petrochemicals sectors, our core markets, along with resultant corporate restructurings and consolidation, were the primary causes for the shortfall in third quarter revenue," said Larry Evans, chairman and CEO of Aspen Technology. "We saw no decline in our competitive win rate, and we continued to see solid demand for our solutions, which help process manufacturers become more competitive. However, decisions are taking longer and the sales cycles are more complex in this environment. Consequently, we have taken decisive actions to adjust our strategy and tactics accordingly, as well as our cost structure. "First, in light of protracted weakness in our core vertical markets, we have taken aggressive steps to significantly reduce our overall cost structure by shrinking our headcount worldwide, streamlining operations, and consolidating facilities. These actions should better align revenues and expenses and are intended to enable us to return to profitability in the near term. Second, we have made some changes within the sales organization to focus more senior resources on day-to-day management of the sales process. And third, we are focussing a larger proportion of our resources on supply chain and Plantelligence opportunities, where our solutions are clearly differentiated, and where we have seen strong market demand and recent competitive success." In connection with this restructuring, AspenTech is reducing its staff by approximately 200 employees, about 12 percent of the global workforce, as well as consolidating facilities, streamlining operations and -more-

As a result of these measures, AspenTech expects to report a $17-19 million restructuring charge in the fourth quarter ending June 30, 1999 and reduce substantially its operating costs for fiscal year 2000. "These actions have sharpened our focus on strategic initiatives. The elimination of redundant, non-core activities will enable us to improve our productivity, maintain customer confidence, and concentrate our investments on innovation and customer support, the foundation of our longstanding industry leadership," said Evans. "Longer term, I am confident that we are well-positioned for continued market leadership, with the largest installed base of customers, the most advanced technology base, the most integrated solutions and the largest implementation force in the industry."
