DSET Reports Financial Results for First Quarter

Bridgewater, NJ - April 26, 2001 - (Nasdaq: DSET) - DSET Corporation today reported financial results for the first quarter ended March 31, 2001.

For the first quarter of 2001, total revenues amounted to $3.4 million, as compared with $5.3 million in the fourth quarter of 2000 and as compared to $11.6 million for the first quarter of 2000.

Sales to the competitive service providers (CSPs) —including cable companies, independent LECs, CLECs, and utility companies— that comprise our primary customer base were up 17% sequentially, or $2.8 million in the first quarter of 2001 compared to $2.4 million in the fourth quarter of 2000.

For the first quarter of 2001, license revenues accounted for $1.5 million, or 44.5% of total revenues, and service revenues accounted for $1.9 million, or 55.5% of total revenues.

The loss for the quarter before restructuring and other charges was $7.5 million, or a loss of $0.64 per share on a basic and diluted basis, as compared with net income of $921,000, or $0.08 per share on a diluted basis, for the quarter ended March 31, 2000. In addition to the losses noted above, the company recognized restructuring and other charges of $3.4 million, or $0.29 per share. This resulted primarily from discontinuing the company's Canadian operations and the costs associated with writing off its Canadian product licenses. It also included additional charges for the costs of further consolidation of operations in the United States.

The weighted average number of basic and diluted common shares outstanding for the first quarter of 2001 was 11.6 million and the number of diluted common shares for the first quarter of 2000 was 12.1 million.


First-Quarter Analysis
We won a major contract from Cox Communications valued at over $2 million. One of the largest telecommunications providers in the U.S., Cox is a financially sound, growing company that continues to be successful despite the turmoil in the telecom sector. Cox is an example of the type of competitive service provider that we are targeting as a potential customer for our electronic-bonding gateways.

While the revenue numbers we've reported for the quarter are low, we expected this. We have based our internal plan for 2001 on benefiting from a small increase in capital spending by our customers in the third and fourth quarters of this year. Consequently, $3.4 million in revenues for the first quarter is close to the expectations set under our plan.

In the area of expense management, we took significant additional steps in the quarter to re-size the company and focus on developing and selling gateways to competitive service providers in the United States. Our approach was to ensure that we could live up to the agreements that we had made with our customers in the United States and Canada. Secondly, we wanted to be able to continue to enhance our products so that we could maintain our competitive position and win new accounts during this year and next.

In addition to closing on the sale of our Chinese subsidiary in exchange for partial ownership in the acquiring company, we also closed our Canadian subsidiary's facility in Toronto, as we did not believe that the reduced revenue potential from Canadian CSPs would translate into profits.

These actions, coupled with attrition and additional reductions in employee headcount in the first quarter, should enable us to end April 2001 with approximately 175 people. We had approximately 320 employees on December 31, 2000.

Looking Forward

From a product development perspective, we continue to make excellent progress with moving our gateways over to our Java-based Next Generation Platform. Utilizing software-industry standards but enriched by our own expertise, this is the software base upon which we plan to expand our business, whether it is to Europe or to different industries within the United States. Feedback from customers, potential OEM partners, and prospects has been very positive.

We plan to release at least 18 new versions of our products by the end of the year, including a major upgrade to our ezLocal gateway, which has already been deployed by many competitive service providers across the U.S. We are also exploring the enterprise market, as the largest companies have extensive telecommunications networks and need to communicate efficiently with their service providers.

We continue to make progress in our partnership with Siebel Systems. We believe that the interface between our trouble administration gateway and their customer relationship management (CRM) system will be validated in the second quarter of this year. Our competitors do not have a product comparable to our ezTroubleAdmin gateway and we believe that there is also the potential for interfacing other DSET gateways with Siebel's CRM software.

We have debated whether or not to provide guidance for 2001 because there is so much uncertainty about the capital spending outlook for our customer base. With our stock trading at just above $1 per share, we believe our investors have concluded that the market for our gateway products may be too limited due to the challenges faced by competitive service providers. Therefore, with this in mind, we have decided to give guidance regarding what we believe is achievable this year.

Looking back to mid-year 2000, we thought at the time that sales to competitive service providers could produce $80 million to $90 million in revenues in 2001. We now see the potential to generate between $20 million and $25 million in revenues from this market. This assumes that there is limited revenue in the second quarter and that business picks up in the third and fourth quarters.

To break even at our current expense levels, we estimate needing $10 million of quarterly revenue. We anticipate approaching this level in the fourth quarter of this year and will continue to look for new ways to increase revenues and reduce operating expenses while achieving our longer-term goals. The projected loss for 2001 before restructuring and other charges at the revenue levels mentioned above could be between $15 million and $20 million.

At the low end of our projected revenue range ($20 million), we could end 2001 with approximately $14 million in cash. At the high end, we could end with about $19 million. This assumes no cash outlays for acquisitions or other unanticipated events.

Is this achievable? We think so. We started the year with a backlog of more than $6.5 million and have already picked up another $2 million to $3 million. Is there $10 million to $15 million in business in the gateway market in the remaining months of 2001? We believe so.

We have surveyed most of our prospective customers and more than 40 indicated that they would like to purchase gateways over the next 6 to 12 months. Will their cash position during this period allow them to invest in gateways? We can't be sure at this time.

We see electronic-bonding gateways as one product line among many if we are successful in expanding our suite of solutions via acquisitions or the development of new products internally. We continue to explore the possibility of partnering with private OSS companies that have recognized that their valuations are dramatically reduced and their chances for an IPO may be limited for the foreseeable future. We believe that we can produce a greater return to shareholders over the next few years if we pursue a selective expansion strategy in the OSS space rather than try to sell the company in the short term.

We have been a company that has refocused itself many times to take advantage of the changing landscape in the telecom industry, and we plan to continue to do the same over the next few years. Through the second quarter of 2000, we had 29 consecutive quarters of profitability and we are working diligently to get back on that track.
