(Nasdaq: TELM), today reported its results for the first quarter ended March 31, 2003. On a U.S. GAAP basis, the company's net loss for the first quarter was approximately $37.4 million, or a loss of $0.38 per basic and diluted share. For the fourth quarter 2002, on a U.S. GAAP basis, the company's net loss was approximately $56.5 million, or a loss of $0.57 per basic and diluted share. Excluding non-cash charges related to equity issuances, stock-based compensation expense, amortization, restructuring charges and impairment of long-lived assets, Tellium's pro forma net loss for the first quarter ended March 31, 2003 was approximately $8.6 million, or a loss of $0.09 per basic and diluted share, compared to a pro forma net loss of approximately $17.2 million, or $0.17 per basic and diluted share, during the fourth quarter of 2002. As of January 1, 2003, Tellium's pro forma results now include depreciation expense. For consistency, Tellium adjusted its pro forma net loss for the fourth quarter of 2002 to include depreciation expense. A reconciliation of net loss on a U.S. GAAP basis and on a pro forma basis is provided in a table immediately following the Pro Forma Consolidated Statement of Operations. Revenues were approximately $10.1 million during the first quarter of 2003, compared with approximately $2.9 million in the fourth quarter of 2002. For the quarter ended March 31, 2003, gross profit on a U.S. GAAP basis was approximately $1.1 million, resulting in a gross margin of 10%. On a pro forma basis, gross profit was approximately $4.9 million, resulting in a gross margin of 48%. A reconciliation of gross profits and gross margins on a U.S. GAAP basis and on a pro forma basis is provided in a table immediately following the Pro Forma Consolidated Statement of Operations. Tellium ended the first quarter of 2003 with approximately $157.2 million of cash on hand, which reflects a reduction in cash of approximately $13.8 million during the quarter. Tellium's reduction in cash was approximately $1.2 million less than the $15.0 million cash-burn that the company had projected in its earnings call on January 29, 2003. Effective January 1, 2003, Tellium adopted SFAS No. 123, Accounting for Stock-Based Compensation. Tellium selected the prospective method of adoption described in SFAS No. 148, Accounting for Stock-Based Compensation Transition Disclosure. The application of SFAS No. 123 resulted in a non-cash charge of $18.4 million, which is included in stock-based compensation expense for the quarter ended March 31, 2003. As a result of its business restructuring announced in January 2003, Tellium recorded a restructuring charge of approximately $6.7 million in the quarter ended March 31, 2003 associated with a workforce reduction and the consolidation of corporate facilities. This restructuring charge is included in the $7.4 million in charges related to restructuring and the impairment of long-lived assets. "Through our aggressive actions to reduce operating costs, I believe we have achieved the first phase of our strategy - stability. Now, we are squarely focused on attaining growth and ultimately profitability," said Harry Carr, chairman of the board and chief executive officer of Tellium. "We are starting 2003 on the right note. We met or exceeded the guidance we provided in January, and our Aurora switches are in the process of being deployed in Cable & Wireless' global network. I am very proud of what the Tellium team has done to meet the challenges in this very difficult environment. I believe that we are well positioned for success."

Tellium's management believes that non-GAAP measures, presented with the U.S. GAAP financial measures, provide useful information to investors because they assist investors in better understanding the company's liquidity and cash position which enables them to better assess the company's quarterly operations. In addition, since we have historically reported non-GAAP results to the investment community, we believe the inclusion of non-GAAP numbers provides consistency in our financial reporting. Tellium's management recognizes that non-GAAP results are not a substitute for U.S. GAAP measures. However, the non-GAAP results are a helpful tool in assisting Tellium's management to better understand and manage its business. Tellium's management uses the non-GAAP financial measures as an alternative means for assessing quarterly operations results and projecting the ongoing costs of operations. Notes - ----- 1 As discussed above, pro forma net loss of approximately $11.5 million was originally reported for the three months ended December 31, 2002. These pro forma results excluded depreciation charges of approximately $5.6 million. As of January 1, 2003, we no longer exclude depreciation expense from our pro forma results. The pro forma loss of approximately $17.2 million in the presentation above has been revised to provide a comparison on a consistent basis. ###
