INDEPENDENT AUDITORS’ REPORT

Board of Directors and Stockholders
VocalData, Inc.

We have audited the accompanying balance sheet of VocalData, Inc. (the “Company”) as of December 31, 2003 and the related statements of operations, changes in stockholders’ equity and cash flows for the year then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material respects, the financial position of VocalData, Inc. as of December 31, 2003 and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

The Company was in the development stage at December 31, 2002; during 2003, the Company is considered to be no longer in the development stage and to have commenced its planned principal operations. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company’s attainment of profitable operations is dependent on future events, including attaining adequate financing and achieving a level of sales adequate to support the Company’s cost structure. The Company’s recurring losses and negative cash flow from operations raise substantial doubt about its ability to continue as a going concern. Management’s plans concerning these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

The accompanying balance sheet of the Company as of June 30, 2004 and the related statements of operations and cash flows for the six months ended June 30, 2004 and 2003, and changes in stockholders’ equity for the six months ended June 30, 2004 were not audited or reviewed by us and, accordingly, we do not express an opinion or any other form of assurance on them.

NOTES TO FINANCIAL STATEMENTS
YEAR ENDED DECEMBER 31, 2003 AND
SIX MONTHS ENDED JUNE 30, 2004 AND JUNE 30, 2003 (unaudited)

1.	DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation - The accompanying unaudited financial statements for the six months ended June 30, 2004 and 2003, have been prepared in accordance with accounting principles generally accepted in the United States and the requirements of the Securities and Exchange Commission for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the six-month period ended June 30, 2004 are not necessarily indicative of results that may be expected for the year ending December 31, 2004.
	Business—VocalData, Inc. (the “Company”) develops and markets softswitch solutions for carrier-grade voice services and enhanced applications to communications service providers meeting the data and voice needs of businesses over Internet Protocol (“IP”) networks. The Company was incorporated in 1996 as a Texas corporation, commenced operations January 1, 1998 and is headquartered in Richardson, Texas. On February 5, 2003, the Company changed its state of incorporation to Delaware.
	The Company was considered to be in the development stage through December 31, 2002. During 2003, the Company achieved a sales level considered as sufficiently significant to no longer be in the development stage and to have commenced its planned principal operations.
	Going Concern—These financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company’s continuation as a going concern is dependent upon its ability to achieve a level of sales adequate to support the Company’s cost structure, to generate sufficient cash flow, to obtain additional financing and, ultimately, to attain successful operations. The Company has incurred significant recurring losses and negative cash flow from operations. These factors raise substantial doubt about the Company’s ability to continue as a going concern.
	The Company plans to continue to increase sales, raise additional capital as required and discuss with candidate companies their interest in acquiring the Company. However, the Company cannot provide any assurances that these plans will be achieved and sufficient funding will result. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.
	Use of Estimates—The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Differences from those estimates are recognized in the period they become known.
	Cash Equivalents include short-term, highly liquid investments purchased with remaining maturities of three months or less.

8

Short-Term Cash Investments consisted of certificates of deposit with original maturities of more than three months and less than one year that were recorded at amortized cost, which approximated their market value.

Inventories are stated at the lower of cost (first-in, first-out method) or market.

Equipment is stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the assets, which primarily range from two to five years.

Licenses primarily consist of prepaid software license fees that are being amortized to cost of revenues over one to three years on a straight-line basis and are stated net of accumulated amortization of $490,887 and $81,675 at December 31, 2003 and June 30, 2004 (unaudited), respectively.

Long-Lived Assets are reviewed periodically, and impairment is recognized if the estimated undiscounted future cash flows are less than the carrying value of the related assets.

Revenues from equipment sales are recognized when the equipment product is shipped and the customer has accepted the product and any related software. Revenues from perpetual software license agreements are recognized as revenue upon receipt of an executed license agreement, or an unconditional order under an existing license agreement, and shipment of the software, if there are no significant remaining vendor obligations, collection of the revenue is probable and payment is due within one year. Revenues from software maintenance services are recognized ratably over the term of the maintenance period. Revenues from other services and equipment rentals are recognized when earned.

For arrangements involving multiple elements, the Company allocates revenue to each component of the arrangement using the residual value method, based on the vendor-specific objective evidence of the fair value of the various elements. These elements may include one or more of the following: equipment, software licenses, maintenance and support, and other services. The Company defers revenue from the arrangement equivalent to the fair value of the undelivered elements. Fair values for the future maintenance and support services are based upon the published prices for renewals of maintenance and support contracts. Fair value of other future services is based upon separate sales of those services to other customers. Under the residual method, any discounts that exist are attributed entirely to the delivered elements, which typically are hardware and software licenses.

Research and Development costs are expensed as incurred until technological feasibility of a software product is established. The Company has defined attainment of technological feasibility as completion of a working model. The period of time beginning with the establishment of a working model and ending when a product is offered for sale is typically very short. Accordingly, costs eligible for capitalization have been insignificant. To date, the Company has not capitalized any software development costs.

Deferred Income Taxes are provided using the asset and liability method for temporary differences between the tax basis of an asset or liability and its reported amount in the financial statements, and are offset by the necessary valuation allowances.

Stock-Based Compensation arising from stock option grants is accounted for by the intrinsic value method under Accounting Principles Board (“APB”) Opinion No. 25. Statement of Financial Accounting Standards (“SFAS”) No. 123 encourages (but does not require) compensation arrangements with employees to be measured based on the fair value of the equity instrument awarded.

No compensation cost has been recognized for the stock options because the exercise price of the Company’s stock option grants was equal to the estimated fair market value of the underlying stock on the date of grant. Had compensation costs for such grants been determined based on the fair value

9

method for the options at the grant date, consistent with SFAS No. 123, the Company’s net loss for 2003 would have been as follows:

	Year Ended
	December 31,
	2003
Net loss – as reported	$	(10,951,116	)
Fair value-based compensation expense		(172,865	)
Pro forma net loss	$	(11,123,981	)

	For the pro forma calculation above, the weighted average fair value of options granted during 2003 as of the date of grant was estimated to be $0.033 per share using the Black-Scholes option-pricing model with the following weighted average assumptions: dividend yield—0%, no expected volatility (because the Company’s stock is not publicly traded), risk-free interest rate—4.31% in 2003 and expected option life—five years.
2.	SIGNIFICANT CUSTOMERS

LONG-TERM DEBT

In July 2000, the Company entered into a Loan and Security Agreement (the “Agreement”) with a bank to finance purchases of equipment, up to a total of $2 million. Pursuant to the terms of the Agreement, the Company received advances to finance six separate purchases of equipment during 2000 totaling $1,697,512 and two separate purchases of equipment during 2001 totaling $302,487. Each of the advances is due in 36 monthly installments. The advances bear interest at a rate, which is fixed during the payment period of 36 months, equal to a reference rate, as defined in the Agreement, on the date of the advance plus 2.75%. The Agreement is subject to certain nonfinancial covenants. The Agreement is collateralized by a first-priority lien on all assets of the Company except for intellectual property.

11

The outstanding balances at June 30, 2004 and December 31, 2003 arising from advances received by the Company during 2001 and 2000 are summarized as follows:

	June 30,
	2004		December 31,		Interest
Date of Advance	(unaudited)		2003		Rate		Monthly Payment Amount
January 31, 2001				5,036		7.57	$5,067 with a final payment of $9,825 on January 1, 2004
March 29, 2001		1		12,706		7.50	$4,289 with a final payment of $8,324 on March 1, 2004
	$	1	$	17,742

	As part of the Agreement in 2000, the Company issued to the bank a warrant to purchase 53,332 shares of Series A Preferred stock at an exercise price of $1.50 per share. The warrant is currently exercisable and expires in July 2007. The fair value of the warrant was calculated using the Black-Scholes option pricing model and resulted in a nominal value at the date of grant.
6.	STOCKHOLDERS’ EQUITY
	Common Stock—In 2003, authorized common shares were increased to 235,000,000, as discussed below.
	Convertible, Series A Redeemable Voting Preferred Stock—In September and November 1999, the Company sold 6,514,286 and 4,914,286 shares, respectively, at a purchase price of $0.875 per share. In February 2000, the Company sold 3,823,370 shares at a purchase price of $0.875 per share. Each share of Series A Preferred is convertible into one share of common stock and has voting rights equal to its applicable common stock conversion amount. Upon consummation of a qualified public offering of common stock, each share of Series A Preferred outstanding will be converted automatically into common stock.

All holders of the Company’s Series Preferred were eligible to participate on a pro rata basis in the Series C Preferred round. Series Preferred stockholders who elected not to participate at the pro rata level were subject to involuntary conversion of some or all of their Series Preferred to the Company’s common stock. As a result, 1,017,567 shares of Series A Preferred and 529,245 shares of Series B Preferred were converted to 1,850,411 shares of common stock.

Preferred Stock Dividends and Redemption Rights—Senior Preferred earns a 6% cumulative dividend. Accrued but unpaid dividends totaling $9,850,248 as of December 31, 2002 for the Series Preferred were cancelled in the Series C Preferred round and future dividends discontinued. The Senior Preferred is senior in liquidation to the Series Preferred, common stock and any other junior stock issued, with Senior Preferred liquidation amounts equal to the original issue prices plus any accrued unpaid cumulative dividends. The Series C-1 Preferred has an additional liquidation preference amount of $0.290511 per share.

Holders of Senior Preferred and Series Preferred may elect at any time to convert their shares to common stock at specified conversion rates. Shares of Senior Preferred and Series Preferred automatically convert to common stock at specified conversion rates upon either the closing of a qualified IPO or the election of 66-2/3% of the outstanding Senior Preferred. In connection with the Senior Preferred issuances, Series Preferred conversion rates were revised and redemption dates extended to 50% of shares in both October 2009 and October 2010. The Series Preferred redemption price is equal to the Series A original issue price or Series B original issue price, with certain specified adjustments.

After June 25, 2008, the holders of 66-2/3% of the outstanding shares of Senior Preferred may elect to require the Company to redeem in two installments all outstanding shares of Senior Preferred. The redemption amount will be the greater of the liquidation amount, excluding any additional liquidation preference, and fair market value as properly determined in good faith by a majority of the Board of Directors.

Common Stock Reserved—Common shares reserved at December 31, 2004 and June 30, 2004 for possible future issuance are as follows:

	December 31, 2003		June 30, 2004

Common shares reserved for possible future issuance		148,149,072		148,103,622

Stock Option Plan—The Company had reserved 10,812,000 shares of common stock for the 1998 Stock Option Plan (the “1998 Plan”). Under the terms of the 1998 Plan, incentive options to purchase common stock and rights to purchase restricted stock may be granted to employees and nonemployees at the discretion of the board of directors. The options vest over a three-year period for options granted in 1998 and over a four-year period for options granted since the beginning of 1999.

13

Options expire 10 years after the date of grant. In October 2003, the Company revised the number of shares of common stock reserved for the stock option plan to 24,000,000.

In August 2003, the Company announced a voluntary stock option exchange program for its eligible employees. Under the program, Company employees were offered the opportunity to cancel certain outstanding stock options to purchase shares of common stock previously granted to them. In exchange, these employees will receive an equal number of new options that will be granted under the 1998 Plan. The new options are to be granted at a future date, at least six months and one day from the cancellation date of August 7, 2003. The exercise price of these new options will be equal to the fair market value of the Company’s common stock on the date of grant.

In connection with the voluntary stock option exchange program, the Company accepted for cancellation options to purchase 5,841,036 shares of its common stock. The Company subsequently granted new options to purchase 5,796,036 shares of its common stock on February 9, 2004 at an exercise price of $0.1719 per share in exchange for the options surrendered and accepted under the program.

Options to purchase 9,168,153 shares of common stock were granted in 2003; 5,621,286 of these options to purchase common shares at an exercise price of $0.1719 per share were granted to employees who accepted the Company’s offer to cancel their outstanding stock options in August 2003. For accounting purposes, these option grants are considered replacement awards for the canceled options and are accounted for as variable options from the grant date to the exercise date. Accordingly, the implicit value of these replacement options will be remeasured at each reporting date, and any compensation expense will be recorded. At December 31, 2003, the estimated fair value of the underlying common stock does not exceed the exercise price of the replacement options; therefore, no compensation expense for these grants has been recorded in the 2003 statement of operations.

Stock option transactions in 2003 and six months ended June 30, 2004 (unaudited) were as follows:

In August 2002, the Company issued options to acquire 1,611,653 shares of common stock at $.50 per share to a key employee with the right of exercise contingent on performance criteria. The exercise of the award of 537,214 options was contingent upon the Company achieving $10 million or more of revenues in 2002; accordingly, the options were canceled at December 31, 2002. The exercise of the award of 1,074,439 options is contingent upon achieving defined proceeds from a corporate change of $200 million or more within 10 years. These options were voluntarily canceled in August 2003.

The following table summarizes certain information about the Company’s stock options at June 30, 2004 (unaudited):

In February 2004, options to purchase 4,721,597 shares at $0.1719 were issued to employees who had voluntarily canceled the same number of options in August 2003 (at least six months and one day before the grant date of the options in February 2004.) In February 2004, the Company entered into an agreement with a key employee, which was approved by the Board in February 2004. Consistent with this agreement, on February 9, 2004, the Company issued options to acquire 1,074,439 shares of common stock at $0.1719. The exercise of these options is contingent upon achieving defined proceeds from a corporate change of $200 million or more within 10 years. These contingent options will be accounted for as a variable award. Accordingly, the then current fair value of the 1,074,439 outstanding options will be recorded as expense over the appropriate period beginning when achievement of the contingent performance criteria is considered likely and will be remeasured until the awards are ultimately exercised or terminated.

TEKELEC
UNAUDITED PRO FORMA CONDENSED
CONSOLIDATED FINANCIAL STATEMENTS

     On September 20, 2004, Tekelec, a California corporation (“Tekelec”), completed the acquisition of all of the outstanding shares of capital stock of privately held VocalData, Inc., a Delaware corporation (“VocalData”). The acquisition was accomplished by means of a triangular merger of a new wholly owned subsidiary of Tekelec (Punkydoo Inc.) with and into VocalData (the “Acquisition”). As a result of the Acquisition, VocalData is the surviving corporation and a wholly owned subsidiary of Tekelec.

     The Acquisition was consummated pursuant to the terms of an Agreement and Plan of Merger dated as of September 14, 2004, among Tekelec, VocalData, Punkydoo Inc. and Core Capital Partners, L.P., as Representative (the “Representative”) of the preferred stockholders of VocalData (the “Merger Agreement”).

     Tekelec paid to the preferred stockholders of VocalData, in exchange for their interests in VocalData, consideration in the total amount of approximately $27,500,000, consisting of (i) an aggregate cash amount of $14,500,000, and (ii) 779,989 shares of Tekelec Common Stock, which number of shares is subject to reduction for certain working capital adjustments. The value of the 779,989 shares is equal to approximately $13,000,000 based on the closing sales price of Tekelec’s Common Stock on the Nasdaq National Market on September 20, 2004. The number of shares was computed pursuant to the terms of the Merger Agreement by dividing $14,500,000 by the average of the closing sales price per share of Tekelec’s Common Stock on the Nasdaq National Market for the ten trading days ending on the second trading day prior to the closing of the merger transaction. The parties have placed approximately $5,220,000 (based on the closing sales price of Tekelec Common Stock on September 20, 2004) of the stock merger consideration (consisting of 311,998 shares of Tekelec Common Stock) into escrow with U.S. Bank National Association for 18 months following the closing of the transaction for the satisfaction of (i) any indemnification claims made by Tekelec under the Merger Agreement, and (ii) certain working capital adjustments under the Merger Agreement. The shares in escrow will be held in accordance with the terms of an Escrow Agreement dated September 20, 2004 among Tekelec, the Representative and the Escrow Agent.

     Subsequent to the Acquisition, 69 VocalData officers and employees were granted, pursuant to Nasdaq Marketplace Rule 4350(i)(1)(A)(iv), employment inducement stock options to purchase a total of 1,083,400 shares of Tekelec Common Stock. The number of shares subject to these grants amounted to less than 2% of the outstanding shares of Tekelec Common Stock as of the date of grant. All such options have an exercise price equal to the closing sales price per share of Tekelec Common Stock on the Nasdaq National Market on September 20, 2004 (i.e., $16.73), and will vest over a four-year period.

     In addition, on the closing date eight VocalData officers and key employees were granted, pursuant to Nasdaq Marketplace Rule 4350(i)(1)(A)(iv), restricted stock units covering a total of 18,000 shares of Tekelec Common Stock. The restricted stock units will vest one year from the grant date.

     The 779,989 shares of Tekelec Common Stock issued to the preferred stockholders of VocalData upon consummation of the merger were issued pursuant to the exemption from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), afforded by Section 4(2) of the Securities Act and Rule 506 of Regulation D thereunder, based in part upon Tekelec’s reasonable belief that the preferred stockholders are accredited investors within the meaning of Regulation D.

     For a more complete description of the terms of the Acquisition, please refer to the Agreement and Plan of Merger and related transaction documents, which are included or incorporated by reference as exhibits in our Current Report on Form 8-K filed with the Commission on September 24, 2004.

     The following unaudited pro forma condensed consolidated financial statements give effect to Tekelec’s acquisition of VocalData. The unaudited pro forma condensed consolidated balance sheet as of June 30, 2004 assumes that the Acquisition was consummated as of June 30, 2004. The unaudited pro forma condensed consolidated statement of operations for the year ended December 31, 2003 and the six months ended June 30, 2004 assumes that the acquisition was consummated on January 1, 2003. The pro forma condensed consolidated statements of operations combine the pro forma results of Tekelec giving effect to the acquisitions of Santera Systems, Inc. (“Santera”) and Taqua, Inc. (“Taqua”) consummated on June 10, 2003 and April 8, 2004, respectively, as if the acquisitions occurred on January 1, 2003.

     The transaction has been accounted for as an acquisition by Tekelec using the purchase method, with the VocalData assets acquired and the liabilities assumed reflected at their estimated fair values. The pro forma VocalData adjustments included in the following unaudited condensed consolidated pro forma financial statements represent a preliminary determination of the purchase price allocation based on available information as of the date of this filing of this Current Report on Form 8-K/A, and there can be no assurance that the actual adjustments will not differ significantly from such pro forma adjustments.

     The unaudited pro forma condensed consolidated financial statements are not necessarily indicative of the results that would have occurred if the Acquisitions had been consummated as of the indicated dates or of the results that may occur in the future.

     The unaudited pro forma condensed consolidated financial statements should be read in conjunction with the historical consolidated financial statements of Tekelec, together with the related notes thereto, included in Tekelec’s Annual Report on Form 10-K for the year ended December 31, 2003, Current Report on Form 8-K/A dated June 10, 2003 filed on June 25, 2003 and Current Report on Form 8-K/A dated April 8, 2004 filed on June 22, 2004, all as filed with the Commission, and the separate financial statements of VocalData included in this Form 8-K/A.

B. The following pro forma adjustments give effect to the acquisition of VocalData and as follows (in thousands):

(1)	To reflect the cash consideration of $14,500 paid by Tekelec of which $51 was paid subsequent to the closing date and is included in trade payables.
(2)	To reflect the acquired deferred tax assets of VocalData, which can be utilized on a consolidated Tekelec basis.
(3)	To reflect the increase in goodwill and intangible assets related to the acquisition of VocalData. The total purchase allocation is as follows:

	Thousands
Total cash paid	$	14,500
Fair value of stock issued		13,000
Estimated direct transaction costs		406
Total fair value of consideration paid and direct transaction costs		27,906
Less: VocalData’s net assets acquired		(6,052	)
Less: VocalData’s acquired deferred tax assets		(13,925	)
Less: Adjustment to deferred revenue		(64	)
Add: Estimated deferred tax liability as related to intangibles		2,279
Total fair value step-up in VocalData	$	10,144

The actual purchase allocation will be based on the estimated fair value of VocalData’s assets and liabilities at the date of acquisition. For purposes of the unaudited pro forma condensed consolidated financial statements, the preliminary purchase allocation is estimated as follows:

	Thousands
In-process research and development	$	2,400
Goodwill		1,234
Identifiable intangible assets		6,510

(4)	To reflect the accrual of the estimated direct transaction costs related to the acquisition.

(6)	To record the deferred tax liability related to identifiable intangible assets.
(7)	To eliminate the historical preferred stock and historical shareholders’ equity in VocalData.
(8)	To reflect the stock consideration contributed by Tekelec.
(9)	To record the in-process research and development expense created as a result of the acquisition. This amount is a nonrecurring item that is directly expensed at closing and, accordingly, there is no adjustment in the unaudited pro forma condensed consolidated statement of operations.
(10)	To reflect amortization of identifiable intangible assets created as a result of the acquisition. The identifiable intangible assets and their related estimated lives are as follows:

			Estimated
	Asset		Life
	Amount		in Years
	(Thousands)
Acquired technology	$	5,200		10
Acquired backlog		100		1
Trade names and marks		10		1
Existing customer relationships		500		10
Service contracts		500		1
Non-complete agreements		200		1
	$	6,510

Acquired technology and backlog are being amortized to cost of sales. Amortization of the other identifiable intangible assets is reflected in operating expenses based on the nature of the intangibles.

(11)

To adjust the provision (benefit) for income taxes for the estimated tax effects of the VocalData tax benefits that are utilizable on a consolidated Tekelec basis amounting to $3,723 and $1,859 (at a 34% assumed effective tax rate) and $483,000 and $100,000 of tax benefits related to amortization of identifiable intangible assets for the year ended December 31, 2003 and six months ended June 30, 2004, respectively.
