EVOLVING SYSTEMS ENCOURAGES STOCKHOLDERS TO VOTE THEIR SHARES

ISS Recommends Stockholders Vote FOR all of the Company's Proposals at the May 16th Stockholders' Meeting

        ENGLEWOOD, Colorado—Evolving Systems, Inc. (NASDAQ-EVOL), a leading provider of innovative software solutions and services to the wireless, wireline and IP carrier market, today announced that Institutional Shareholder Services ("ISS"), the leading proxy advisory firm advising institutional investors in proxy voting matters, has recommended that stockholders vote FOR each of the proposals on the agenda for the upcoming annual stockholders' meeting, scheduled for May 16, 2005.

        In its report dated April 26, 2005, ISS reviewed each of the proposals submitted for stockholder vote and recommended a vote FOR all proposals. In addition to election of two directors and ratification of the Board of Directors' selection of the Company's independent accounting firm, the Company is asking its stockholders to vote on two important matters related to its November 2, 2004, acquisition of London-based Tertio Telecoms Limited.


ISS recommends a vote FOR the Conversion of Long-Term Notes Proposal

        In recommending a vote FOR the proposal to approve the exchange of long-term notes into convertible notes, ISS said "Given: (1) the fact that the conversion price currently represents a substantial premium to market price, (2) the reduced interest burden on the company as a result of the proposed conversion, and (3) that the company would not have to repay its debt from its cash flows and have more flexibility with respect to operations and future financing needs, we believe that the conversion warrants shareholder support."


ISS recommends a vote FOR the proposal to Increase its Authorized Shares

        ISS also recommended a vote FOR the Company's proposed increase to authorized shares. The results of ISS' quantitative analysis of such proposals, which takes into account proposals submitted by peer companies and company performance, concluded that the proposed increase was well within its prescribed guidelines on such matters.

        Management encourages all stockholders to promptly cast their votes in favor of each of the proposals to ensure that votes are counted in the tabulation prior to the meeting. If stockholders have questions about the proposals or need assistance voting their shares, they may call D.F. King & Co., Inc., who is assisting the Company in the solicitation, toll-free at 1-800-549-6697.
