WOODLAND HILLS, Calif.--(BUSINESS WIRE)--Nov. 26, 2001

Vertel Corporation (Nasdaq:VRTL), a leading provider of middleware for telecommunications networks, today announced that it has completed the sale of network management tools and a customized network management solution developed by Vertel's professional services unit, to ACE*COMM, a global leader in enterprise telemanagement applications and advanced Convergent Mediation(TM) solutions for wired and wireless voice, data, and Internet communications providers.

ACE*COMM will be using the customized solution to integrate their billing mediation applications with their Asian customer's Alcatel E10 switch.

"We are very pleased that ACE*COMM selected our Network Management software and solution expertise for this project," said Marc Maassen, president and CEO of Vertel. "Given ACE*COMM's track record for delivering high quality applications to their global customers, we consider this purchase further validation that Vertel remains an acknowledged expert in developing middleware solutions for the Asian telecommunications marketplace."

The Vertel solution enables ACE*COMM to provide TMN interfaces between two of their applications, their Centralized Access Network Server (CANS(R)) application and their Distributed Call Measurement System (DCMS(R)) application, and their customer's Alcatel E10 switch which requires a TMN interface. The DCMS application collects call detail records (CDRs) from the Alcatel switch and the CANS application delivers those records from the DCMS collector to a downstream billing system.

"Vertel's technology will help us to better serve our customer and provide them with the most innovative and reliable solution," said Mehran Moghaddam, vice president of software engineering at ACE*COMM. "We are pleased with Vertel's ability to deliver on this customized network management solution within the expected timeframes."

Safe Harbor Statement: Except for the historical information presented, the matters discussed in this news release are forward looking statements and are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve risks and uncertainties. These uncertainties include factors that affect all businesses operating in a global market, as well as matters specific to the Company and the markets it serves. Particular risks and uncertainties facing the company at the present include the Company's ability, including financial ability, to continue to invest in research and development necessary for the development of new and existing products (including WebResolve) that are required to offset the continuing decline in Telecommunications Management Network (TMN) revenues; the timely and successful development of existing and new markets; the maturing nature of the TMN product marketplace and the financial uncertainties associated with an anticipated decline in TMN revenues; the fact that some of our products are relatively new and, although we see developing market interest, it is difficult to predict sales for new products such as e*ORB, Mediation Framework, Object Management Frameworks and WebResolve and the market may or may not ultimately adopt these technologies; the length of the Company's sales cycle for most of its products, including e*ORB, Mediation Framework and Object Management Frameworks, making initial license sales and future royalties difficult to forecast; the severe impact that the slowdown in the U.S. economy has had on the telecommunications industry, forcing a number of service providers to cease operations and resulting in the cancellation or postponement of several transactions the company had in progress; additional difficulty in predicting royalty revenue because that revenue is dependent on successful development and deployment by our customers of our products; fluctuation from quarter to quarter in revenue from our professional service unit as a result of a limited number of large consulting contracts; loss of key customer, partner or alliance relationships and the possibility that the Company may not be able to replace the loss of a significant customer; the dependence on a limited number of customers for a significant portion of the Company's quarterly license revenues; size and timing of license fees closed during the quarter which may result in large swings in quarterly operating results and the likely continued significant percentage of quarterly revenues recorded in the last month of the quarter, frequently in the last weeks or even days of a quarter, which further adds to the difficulty of forecasting and leads to a substantial risk of variance from actual results; and the Company's ability to control expenditures at a level consistent with revenues.

The Company also considers the recent terrorist attacks on the World Trade Center in New York City and the Pentagon in Washington D.C., as having had a significantly adverse impact on the world securities markets as well as the United States economy in general. The extent of the impact on the Company cannot be quantified at this time. Although the Company did not have any offices in any of the effected areas, the current United States concerns over domestic security and the state of the economy may cause customers to delay or cancel orders with us. Such delays and cancelations could materially adversely impact our revenue and results of operations.

Additionally, more general risk factors include the possible development and introduction of competitive products and new and alternative technologies by the Company's competitors; the increasing sales and marketing costs of attracting new and retaining existing customers; pricing, currency and exchange risks; governmental and regulatory developments affecting the Company and its customers; the ability to identify, conclude, and integrate acquisitions on a timely basis; the ability to attract and/or retain essential technical or other personnel; political and economic uncertainties associated with conducting business on a worldwide basis. Readers are cautioned not to place undue reliance on any forward-looking statement and to recognize that the statements are not predictions of actual future results. Actual results could differ materially from those anticipated in the forward-looking statements and from historical results, due to the risks and uncertainties referred to above, as well as others not now anticipated. Further risks inherent in the Company's business are listed under "Risk Factors" in Part I, Item I of Vertel's Annual Report on Form 10-K for the fiscal year ended December 31, 2000 and Form 10-Q for the quarters ended March 31, 2001, June 30, 2001 and September 30, 2001.

The foregoing statements and risk factors are not exclusive and further information concerning the Company and its business, including factors that potentially could materially affect the Company's financial results, may emerge from time to time. It is not possible for management to predict all risk factors or to assess the impact of such risk factors on the Company's business. The Company undertakes no obligation to revise or publicly release the results of any revision to the forward-looking statements.
