TEOCO to Acquire TTI Telecom in an All-Cash Transaction

FAIRFAX, Va. and ROSH HA'AYIN, Israel, June 9, 2010 (GLOBE NEWSWIRE) -- TEOCO Corporation ("TEOCO"), a market leader in providing cost, routing, and revenue management solutions to leading communications service providers worldwide, and TTI Team Telecom International Ltd. (Nasdaq:TTIL), a global supplier of Operations Support Systems (OSS) to communications service providers, announced today that they have entered into a definitive merger agreement, whereby TEOCO will acquire TTI Telecom in a transaction valued at approximately US$58.0 million, subject to adjustments.

Under the terms of the merger agreement, TTI Telecom preferred and ordinary shareholders will receive US$3.00 per share in cash at the closing, without interest and less applicable withholding tax. This purchase price per share may be increased or decreased at closing to the extent that TTI Telecom's cash balance immediately prior to closing is above or below the respective agreed upon amounts, and will be decreased to the extent TTI Telecom's transaction expenses are above an agreed upon amount, with a minimum share price of US$2.90. The Company advises that it currently does not expect an upward adjustment above the US$3.00 per share merger consideration.

The price per share of US$3.00 represents a premium of approximately 50% over the Company's average closing share price during the 90 trading days ended June 8, 2010. The Board of Directors of TTI Telecom approved the agreement and recommended that TTI shareholders vote in favor of the transaction.

Atul Jain, Chairman and Chief Executive Officer, TEOCO Corporation, said, "We believe that adding TTI's employees, assets, and solutions under one umbrella will enable TEOCO to provide unprecedented value to our respective clients. This combination brings together two industry leaders whose solutions contribute greatly to increasing the profitability and success of global communications service providers."

"I am very impressed with the caliber of the people in TTI and their deep expertise in network management. We plan to bring the talent of the two teams together over the next 12 months, which will yield greater innovation for our clients and create an exciting work environment for our employees," Mr. Jain concluded.

Meir Lipshes, Chairman of the Board of Directors and Chief Executive Officer of TTI Telecom, commented on the transaction, "Although encouraged by the latest technical evolutions in the OSS market and by the planning of a new LTE solution, we also recognized, in light of recent years' series of acquisitions of smaller OSS companies by larger competitors, the challenges of continuing the path as an independent public company operating in a competitive and consolidating market. Therefore, after a careful and thorough analysis, and with the completion of extensive negotiations with TEOCO, the Board of Directors has decided to endorse this transaction as being in the best interest of our shareholders, customers and employees. We have high regards for TEOCO and are excited about the future opportunities that this transaction presents to our shareholders, partners, customers and employees."

Key Benefits of the Transaction

This combination will result in a company whose international business will be a significant contributor to its growth which, along with TEOCO's success in North America, will allow it to offer increased value to communications service providers worldwide. TEOCO and TTI Telecom have a combined 35 years of industry expertise and serve over 75 communications service providers worldwide. Other key benefits include:

Greater Value for Customers - The combined company unifies Cost, Revenue, Routing, and Network Management in one global organization. This means greater product integration, improved global customer service, and solutions that deliver greater value for our customers.
Deep Industry Expertise - The combined company will have over 600 employees whose key expertise is dedicated to support global communication service providers. Many of these individuals are thought leaders in LTE, WI-Max, VoIP as well as traditional voice technologies.
Financial Strength and Flexibility- The combined company will be financially strong and profitable. With over 75 global customers, representing 25 countries, the company has the ability to make the R&D investments necessary to support and deploy solutions for the next generation of communication technologies.

Timing; Go-Shop and Approvals

The closing of the transaction is subject to shareholders approval, including separate class meetings of the ordinary and preferred shares; certain regulatory approvals; and other customary closing conditions. There is no financing condition to the obligations of TEOCO to consummate the transaction and it is currently anticipated that the transaction will be consummated in the third quarter of 2010. Upon the closing of the transaction, TTI ordinary shares would no longer be traded on NASDAQ.

Under the terms of the agreement, TTI Telecom may, subject to compliance with various conditions, actively solicit superior proposals from third parties until July 9, 2010 and may consider unsolicited proposals made by third parties. TEOCO has a right to match any superior proposal. TTI Telecom does not intend to disclose developments with respect to this solicitation process, except as may be required by law. There can be no assurance that the solicitation of superior proposals will result in an alternative transaction. If the Company accepts a superior proposal, a break-up fee would be payable by the Company to TEOCO.

Holders of an aggregate of approximately 24% of TTI's outstanding ordinary and preferred shares, on an as converted basis, have entered into voting undertakings with TEOCO under which they have agreed to vote their shares in favor of the transaction. These undertakings will expire upon termination of the merger agreement.
