EXHIBIT 99.6 EXCEL SWITCHING CORPORATION CONSOLIDATED FINANCIAL STATEMENTS AS OF DECEMBER 27, 1997 AND DECEMBER 31, 1998 TOGETHER WITH AUDITORS' REPORT REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON CONSOLIDATED FINANCIAL STATEMENTS To Excel Switching Corporation: We have audited the accompanying consolidated balance sheets of Excel Switching Corporation (a Massachusetts corporation) and subsidiaries as of December 27, 1997 and December 31, 1998, and the related consolidated statements of income, stockholders' equity and comprehensive income and cash flows for each of the three years in the period then ended. The consolidated financial statements give retroactive effect to the merger with RAScom, Inc. and subsidiary (RAScom) on May 10, 1999, which has been accounted for as a pooling of interests, as described in Note 1. 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 audits. We conducted our audits in accordance with generally accepted auditing standards. 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 audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Excel Switching Corporation and subsidiaries as of December 27, 1997 and December 31, 1998, and the results of their operations and their cash flows for each of the three years in the period then ended, after giving retroactive effect to the merger with RAScom, as described in Note 1, all in conformity with generally accepted accounting principles.

F-7 EXCEL SWITCHING CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 1998 (1) OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES Excel Switching Corporation (Excel) is a leading provider of open switching platforms for telecommunications networks worldwide. Excel develops, manufactures, markets and supports a family of open, programmable, carrier-class switches that address the complex enhanced services and wireless and wireline infrastructure needs of network providers. Excel sells to a variety of customers in the worldwide telecommunications market, including applications developers, original equipment manufacturers (OEMs), system integrators and network service providers. On May 10, 1999, Excel acquired RAScom, Inc. and subsidiary (RAScom), a company that develops, manufactures, markets and supports a comprehensive line of open system, remote access servers. Excel exchanged 1,021,187 shares of common stock of all the outstanding shares of RAScom common stock, and exchanged options to purchase 78,753 shares of Excel for all the outstanding options of RAScom; 102,122 of the shares issued were placed into escrow as security for indemnification obligations of RAScom relating to representations, warranties and tax matters. This merger has been accounted for as a pooling of interests. Accordingly, the accompanying financial statements have been retroactively restated to reflect the transaction as if Excel and RAScom (the Company) had operated as one entity since inception. The Company has incurred approximately $2.1 million of merger-related costs, which will be included in the consolidated statement of income for the quarter ended June 30, 1999. The accompanying consolidated financial statements reflect the application of certain accounting policies, as described below and elsewhere in these notes to consolidated financial statements. (a) PRINCIPLES OF CONSOLIDATION These consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. (b) INTERIM FINANCIAL STATEMENTS The accompanying consolidated financial statements as of March 31, 1999 and for the three months ended March 28, 1998 and March 31, 1999 are unaudited, but in the opinion of management, include all adjustments, consisting only of normal recurring adjustments necessary for a fair presentation of results for the interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally F-8 accepted accounting principles have been omitted with respect to these unaudited financial statements, although the Company believes that the disclosures included are adequate to make the information presented not misleading. Results for the three months ended March 31, 1999 are not necessarily indicative of the results that may be expected for the year ended December 31, 1999. (c) CHANGE IN FISCAL YEAR-END During 1998, the Company elected to change its fiscal year-end from the last Saturday in December to December 31 to better synchronize its fiscal periods with the majority of its customers and suppliers. RAScom's fiscal year has always ended on December 31. In the accompanying consolidated financial statements, 1996 refers to the fiscal year ended December 28, 1996 for Excel and December 31, 1996 for RAScom; 1997 refers to the fiscal year ended December 27, 1997 for Excel and December 31, 1997 for RAScom; and 1998 refers to the fiscal year ended December 31, 1998 for both Excel and RAScom. (d) MANAGEMENT ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The market for telecommunications equipment in which the Company operates can be characterized as rapidly changing because of several factors including technological advancements, the introduction of new products and services by the Company and its competitors, and the increasing demands placed on equipment in worldwide telecommunications networks. Significant assets and liabilities with reported amounts based on estimates include accounts receivable, inventory, intangible assets and accrued expenses for post sale support costs, warranty costs and sales returns and allowances. While the Company believes its estimates are adequate, actual results could differ from those estimates. (e) REVENUE RECOGNITION Revenue is generally recognized when all significant contractual obligations have been satisfied and collection of the resulting receivable is reasonably assured. Revenue from product sales is recognized at time of delivery and acceptance, and after consideration of all the terms and conditions of the customer contract. Revenue from sales-type leases is recognized at the date of shipment, net of reserves for uncollectable amounts. Revenue from operating leases or leases for which the collection of the lease payments is not predicable is recognized ratably over the lease term, and the related equipment is depreciated using the straight-line method over its estimated useful life (see Note 6). Revenue from providing services and post-sale support are recognized at time of performance. The Company provides for anticipated product returns and warranty costs at the time of revenue recognition. F-9 (f) SOURCES OF SUPPLY AND THIRD-PARTY MANUFACTURING RELATIONSHIPS Certain components used in the manufacture of the Company's products are currently available only from single- or sole-source suppliers. In addition, the Company relies on a limited number of third parties to manufacture certain other components and subassemblies. Shortages resulting from a change in arrangements with these suppliers and manufacturers could cause delays in manufacturing and product shipments and possible deferral or cancellation of customer orders. (g) RESEARCH AND DEVELOPMENT AND SOFTWARE DEVELOPMENT COSTS Research and development costs have been charged to operations as incurred. The Company believes its current process for developing software is essentially completed concurrently with the establishment of technological feasibility. Accordingly, no software development costs have been capitalized to date. (h) CONCENTRATIONS OF CREDIT RISK Financial instruments that subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, marketable securities and trade accounts receivable. The Company's investments are in financial instruments of high quality. Concentration of credit risk with respect to trade accounts receivable is limited to customers to whom the Company makes significant sales. Two customers accounted for approximately 14% and 12%, respectively, of accounts receivable at December 27, 1997. Another customer accounted for approximately 11% of accounts receivable at December 31, 1998 (see Note 12). To control credit risk, the Company performs regular credit evaluations of its customers' financial condition and maintains allowances for potential credit losses. (i) FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying amounts of the Company's cash and cash equivalents, marketable securities, accounts receivable and accounts payable approximate fair value because of the short-term nature of these instruments. Based on the borrowing rates currently available to the Company, the carrying amounts of debt issued during 1998 in connection with acquisitions approximate fair value. (j) EARNINGS PER SHARE Basic earnings per share was determined by dividing net income by the weighted average common shares outstanding during the period. Diluted earnings per share was determined by dividing net income by diluted weighted average shares outstanding. Diluted weighted shares outstanding reflects the dilutive effect, if any, of common stock options based on the treasury stock method and Redeemable Convertible Preferred Stock on an as-if-converted basis. The calculations of diluted weighted average shares outstanding exclude 459,800 and 141,600 common stock options in 1997 and 1998, respectively, and 126,400 and 27,700 common stock options for the three months ended March 28, 1998 and March 31, 1999, respectively, as their effect would be antidilutive. There were no antidilutive common stock options in 1996. F-10 The calculations of basic and diluted weighted average shares outstanding are as follows (in thousands): Fiscal Years Three Months ------------------------------------ ------------------ 1996 1997 1998 1998 1999 (Unaudited) Basic weighted average common shares outstanding 28,253 28,939 33,406 32,832 34,476 Weighted average common equivalent shares from stock options 4,607 5,619 6,085 6,329 5,820 Weighted average common equivalent shares from preferred stock 165 543 822 822 822 ----------- ----------- ----------- ----------- ----------- Diluted weighted average shares outstanding 33,025 35,101 40,313 39,983 41,118 ----------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- (k) COMPREHENSIVE INCOME Comprehensive income represents the change in equity of a business enterprise resulting from transactions and other events and circumstances from nonowner sources. For fiscal years 1997 and 1998, and for the three months ended March 28, 1998 and March 31, 1999, the only differences between comprehensive income and net income relate to unrealized gains and losses on marketable securities, net of the related tax effect, and foreign currency translation adjustments. The following is a rollforward of accumulated comprehensive income to March 31, 1999 (unaudited): Accumulated Foreign Unrealized Other Currency Gains On Comprehensive Translation Investments Income Beginning balance $36 $107 $143 Current-period change (99) (56) (155) --------------- --------------- --------------- Ending balance $(63) $51 $(12) --------------- --------------- --------------- --------------- --------------- --------------- (2) ACQUISITIONS On September 30, 1998 the Company acquired all of the outstanding capital stock of Quantum Telecom Solutions, Inc. (Quantum), a New Jersey based provider of switch-configuration software. The total consideration of $8.9 million consisted of approximately $5.4 million of cash plus the issuance of promissory notes totaling $3.5 million. On September 30, 1998, the Company also acquired all of the outstanding capital stock of XNT Systems, Inc. (XNT), a supplier of intelligent switch control and comprehensive call-processing and control software based in New Hampshire. The F-11 total consideration of $8.8 million consisted of cash payments of approximately $2.3 million plus the issuance of promissory notes totaling $4.7 million and the assumption of certain liabilities of XNT totaling approximately $1.8 million. These acquisitions were accounted for under the purchase method of accounting, and accordingly, the results of operations from the date of acquisition are included in the Company's consolidated statements of income. The fair market value of assets acquired and liabilities assumed was based on an independent appraisal. The portion of the purchase price allocated to in-process research and development was based on a risk-adjusted cash flow appraisal method and represents projects that had not yet reached technological feasibility and had no alternative future use. This portion of the purchase price was expensed upon consummation of the acquisitions. Based on the independent appraisal, the Company has allocated a portion of the purchase price to certain intangible assets. Intangible assets consist of the following at December 31, 1998 (in thousands): Estimated Useful Life Developed technology 4 years $2,190 Assembled workforce 5 years 350 Goodwill 10 years 7,519 --------------- 10,059 Less--accumulated amortization 357 --------------- $9,702 --------------- --------------- The Company periodically reviews the realizability of its intangible assets and has not recorded any impairment of these assets to date.

In addition, the Company sold the leasing company an existing receivable of approximately $1.0 million. The Company's recourse obligation at March 31, 1999 is approximately $8.5 million, for which it has recorded a reserve of $8.5 million. Because of the credit ratings of certain of these customers and the related recourse obligations, the Company determined it would record the related $7.5 million of revenue ratably as the lease payments are received for the term of the lease or until such time as collection of the underlying lease payments can be reasonably assured.

In some instances, options have been granted at exercise prices below the fair market value on the date of grant. The difference, if any, between the fair market value of shares of the Company's common stock and the exercise price of the option is recognized as compensation expense over the vesting term. During fiscal years 1996, 1997 and 1998, and during the three months ended March 28, 1998 and March 31, 1999, the Company recognized net compensation expense of approximately $60,000, $125,000, $189,000, $39,000 and $97,000, respectively.

(b) 1997 STOCK OPTION PLAN Under the terms of the 1997 Stock Option Plan (1997 Plan), incentive and nonqualified stock options may be granted to employees consultants and directors to purchase an aggregate of 5,000,000 shares of common stock. During 1998, the Company granted 1,567,200 options under the 1997 Plan, of which 1,557,800 options were outstanding at December 31, 1998. F-18 (c) DIRECTOR OPTION PLAN The Company's Non-Employee Director Stock Option Plan (Director Option Plan) provides for the grant of options to purchase an aggregate 225,000 shares of common stock to nonemployee directors of the Company. Each such director will be granted an option to purchase 30,000 shares upon election to the Board of Directors. In addition, each such director will be automatically granted an option to purchase 15,000 shares in each of the two years following the date such person becomes a director. These options will vest 1/3 on grant date, 1/3 one year from grant date and 1/3 two years from grant date. The Plan was amended in May 1999 to terminate the initial grant of options to purchase 30,000 shares and the grant of 15,000 additional shares at each of the next two anniversary dates. Commencing January 1, 2000, each nonemployee director will be automatically granted fully vested options to purchase 1,250 shares of common stock once each quarter provided that the director has been a member of the Board for at least one year.
