Results of the Company’s IEX contact center business unit are presented as income from discontinued operations. Results from continuing operations, which exclude IEX, are also referred to as results from the Company’s Telecom business.

Results from Continuing Operations
Revenue from continuing operations for the second quarter of 2006 was $149.9 million, up 34% compared to $111.5 million for the second quarter of 2005. For the second quarter of 2006, the Company had orders for the Telecom business of $100.4 million, down 31% compared to $145.1 million for the second quarter of 2005.

On a non-GAAP basis, income from continuing operations for the second quarter of 2006 was $13.8 million, or $0.19 per diluted share, compared to income from continuing operations of $2.1 million, or $0.03 per diluted share, for the second quarter of 2005. Please refer to the attached financial statement schedules for a reconciliation of the Company’s GAAP operating results to its non-GAAP operating results.

Please refer to the attached financial statement schedules for a reconciliation of the Company’s GAAP operating results to its non-GAAP operating results.

Results from Discontinued Operations

The sale of the IEX contact center business to NICE Systems, Inc. closed on July 6, 2006 and the operations of IEX have been presented as a discontinued operation. On a GAAP basis, income from discontinued operations in the second quarter of 2006 was $9.6 million, or $0.14 per diluted share, compared to income from discontinued operations of $2.3 million, or $0.03 per diluted share, in the second quarter of 2005. On a GAAP basis, income from discontinued operations for the first six months of 2006 was $12.6 million, or $0.19 per diluted share, compared to income from discontinued operations of $4.1 million, or $0.05 per diluted share, for the first six months of 2005. Included in the income from discontinued operations for the three and six months ended June 30, 2006 was licensing income resulting from the settlement of the Blue Pumpkin litigation of $8.25 million, which contributed approximately $5.3 million after tax, or $0.07 per diluted share. Tekelec will receive six additional annual payments of $500,000 as part of the settlement agreement, which will be recorded as income in future periods. The Company will also record a gain on the sale of discontinued operations in the third quarter of 2006 to reflect the difference between net proceeds received and the book value of IEX shares.

At June 30, 2006, Tekelec’s consolidated cash, cash equivalents and short-term investments totaled $237.2 million, down from $245.3 million at March 31, 2006. Deferred revenues from continuing operations were $257.1 million at June 30, 2006, down from $282.6 million at March 31, 2006.

Frank Plastina, president and chief executive officer of Tekelec, stated “The Company’s strong backlog at June 30, 2006 and our operating performance for the second quarter of 2006 highlight the strength of the Company’s business. While we continue to expect volatility in our revenue and operating results as a result of applying the residual method of revenue recognition, we currently expect that revenues and operating profits from the Telecom business will grow during the second half of 2006 compared to both the first half of 2006 and the second half of 2005. Orders for the first half of 2006 were lower than anticipated, but we expect an increase in orders for the second half of the year “

Consolidated Results

Net income on a consolidated basis for the three months ended June 30, 2006 was $14.6 million, or $0.20 per diluted share, compared to net income on a consolidated basis for the three months ended June 30, 2005 of $0.8 million, or $0.01 per diluted share. Net loss on a consolidated basis for the six months ended June 30, 2006 was $2.0 million, or $0.03 loss per diluted share, compared to net income on a consolidated basis for the six months ended June 30, 2005 of $18.3 million, or $0.26 per diluted share.

SEC Discussion

During the recently completed restatement process, the staff of the Atlanta, Georgia District Office of the Securities and Exchange Commission (the “Commission”) contacted the Company to request that the Company meet voluntarily with the staff to discuss matters related to the Company’s restatement of its financial statements. The Company recently met informally with the staff to discuss the restatement process and its restated financial statements which were included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005 (the “2005 Form 10-K”). The Company intends to continue to fully cooperate with the staff and to furnish additional information if requested to do so.

Conference Call

Tekelec has scheduled a conference call for Monday, August 7, 2006, for management to discuss second quarter 2006 results. The Company also plans to provide on its web site non-GAAP numbers for the second quarter and first six months of 2006 and to discuss during this call certain forward looking information concerning the Company’s prospects for the second half of 2006.

“Live” Webcast and Replay

Tekelec will host a live webcast of its conference call on Monday, August 7, 2006, at 4:45 p.m. EDT. To access the webcast, visit Tekelec’s web site located at www.tekelec.com, enter the Investor Relations section and click on the webcast icon. A webcast replay will be available at approximately 7:45 p.m. on August 7^thand for 90 days thereafter.

Telephone Replay

A telephone replay of the call will also be available for one week after the live webcast by calling either (800) 642-1687 or (706) 645-9291, and entering the conference ID # 3507760.

Non-GAAP Information

Certain non-GAAP financial measures are included in this press release, including a full non-GAAP statement of operations. In the calculation of these measures, Tekelec generally excludes certain items such as amortization of acquired intangibles, restructuring and other charges, non-cash stock-based compensation charges, and unusual, non-recurring gains and charges. Tekelec believes that excluding such items provides investors and management with a representation of the Company’s core operating performance and with information useful in assessing its prospects for the future and underlying trends in Tekelec’s operating expenditures and continuing operations. Management uses such non-GAAP measures and the resulting non-GAAP statements of operations to (i) evaluate financial results,(ii) manage the Company’s operations, and (iii) establish operational goals. Further, each of the individual non-GAAP measures within the non-GAAP statement of operations and the non-GAAP statement of operations itself are utilized by the Company’s management and board of directors to determine incentive compensation and evaluate key trends within the business. In addition, since the Company has historically reported non-GAAP measures to the investment community, the Company believes the inclusion of this information provides consistency in our financial reporting. The attachments to this release provide a reconciliation of each of the non-GAAP measures, including the full non-GAAP statement of operations, referred to in this release to the most directly comparable GAAP measure, GAAP net income from continuing operations. The non-GAAP financial measures are not meant to be considered a substitute for the corresponding GAAP financial measures.

FORWARD-LOOKING STATEMENTS

Certain statements made in this press release are forward looking, reflect the Company’s current intent, belief or expectations and involve certain risks and uncertainties. The Company’s actual future performance may not meet the Company’s expectations. As discussed in the Company’s Form 10-Q for the 2006 first quarter, its 2005 Form 10-K and its other filings with the Commission, the Company’s future operating results are difficult to predict and subject to significant fluctuations. Factors that may cause future results to differ materially from the Company’s current expectations, in addition to those identified in the Company’s filings with the Commission, include, among others, the impact on future operating results of changes in revenue recognition described in the 2005 Form 10-K, the Form 10-Q for the 2006 first quarter, and in prior reports filed with the Commission and the risk that the Company’s financial results for the full year 2006 and for the second half of 2006 will not meet the Company’s expectations. The Company undertakes no obligation to publicly update any forward-looking statements whether as a result of new information, future events or otherwise.

Notes to Unaudited Condensed Consolidated Statements of Operations (in thousands):

(1)

This amount represents restructuring and other costs related principally to reductions in staff associated with the (i) restructuring of our operations in 2006 (the “2006 Restructuring”), (ii) our corporate headquarters and Taqua relocations in 2005, and (iii) the relocation of our manufacturing operations in 2004. The 2006 Restructuring involved the termination of approximately 60 employees across all of our business units, customer service organization and operations group. The majority of the terminated employees worked directly for or in support of the Switching Solutions Group based in Plano, Texas. The estimated annual operating cost savings resulting from the 2006 Restructuring is expected to be between $8.0 and $8.5 million.

(2)

On October 3, 2005, we acquired the remaining shares of Santera capital stock held by the minority shareholders and on that date, Santera became a wholly owned subsidiary of Tekelec. For all periods presented, the results of Santera are included in the consolidated results of operations of Tekelec. The consolidated provision for income taxes does not include any benefit from the losses generated by Santera prior to October 3, 2005 due to the following:

- Prior to October 3, 2005, Santera’s losses could not be included on Tekelec’s consolidated federal tax return because its ownership interest in Santera did not meet the threshold to consolidate under income tax rules and regulations.

- Prior to October 3, 2005, a full valuation allowance had been established on the income tax benefits generated by Santera as a result of Santera’s historical operating losses.

(3) For the three months ended June 30, 2006, the calculation of consolidated diluted earnings per share (including discontinued operations) includes the add-back to net income of $581 for assumed after-tax interest cost related to the convertible debt using the “if-converted” method of accounting for diluted earnings per share. For the six months ended June 30, 2005 the calculation of diluted earnings per share includes the add-back to net income of $1,162 for assumed after-tax interest cost related to the convertible debt using the “if-converted” method of accounting for diluted earnings per share. The weighted average number of shares outstanding for the three months ended June 30, 2006 and for the six months ended June 30, 2005 includes 6,361 shares related to the convertible debt using the “if-converted” method. For all other periods presented, these adjustments were excluded from the calculation of diluted earnings per share as these adjustments were anti-dilutive.
