         This Amendment No. 3 is being filed to amend the Report on Form 8-K
dated May 10, 1999 and filed with the Commission on May 25, 1999, as amended by
Amendment No. 1 on Form 8-K/A, dated May 10, 1999 and filed with the Commission
on July 23, 1999 and as further amended by Amendment No. 2 on Form 8-K/A, dated
May 10, 1999 and filed with the Commission on July 29, 1999 (as amended, the
"Report"). This Amendment No. 3 is being filed to add Exhibit 99.6 (Consolidated
Financial Statements of Excel Switching Corporation as of December 27, 1997 and
December 31, 1998 and the unaudited Consolidated Financial Statements of Excel
Switching Corporation as of March 31, 1999) to the Report. No other changes to
the Report are being made.

         Generally accepted accounting principles do not allow for the
restatement of historical financial statements for a pooling of interests
transaction until results that include post-merger activity have been issued.
The Company has previously filed as Exhibit 99.4 (Supplemental Consolidated
Financial Statements of Excel Switching Corporation as of December 27, 1997 and
December 31, 1998 and the unaudited Supplemental Consolidated Financial
Statements of Excel Switching Corporation as of March 31, 1999) which present
supplemental financial statements reflecting the transaction as if Excel and
RAScom had operated as one entity since inception. On August 16, 1999, the
Company filed with the Commission a Quarterly Report on Form 10-Q for the
quarter ended June 30, 1999. This report presented results that included
post-merger activity. Accordingly, the supplemental financial statements
described above can now be reflected as the Company's historical financial
statements. Exhibit 99.6 updates the financial statements originally presented
in Exhibit 99.4 by removing the supplemental designation of the financial
results and by modifying the Notes to Consolidated Financial Statements for
subsequent events that have occurred since the date of 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.


                                                            ARTHUR ANDERSEN LLP

                           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
<PAGE>



              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.

       (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):

       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):

       The Company periodically reviews the realizability of its intangible
       assets and has not recorded any impairment of these assets to date. The
       following unaudited pro forma summary information presents the combined
       results of operations of the Company, Quantum and XNT as if the
       acquisitions had occurred at the beginning of 1997. This unaudited pro
       forma financial information is presented for informational purposes only
       and may not be indicative of the results of operations as they would have
       been if the Company, Quantum and XNT had been a single entity, nor is it
       necessarily indicative of the results of operations that may be expected
       in the future. Anticipated efficiencies from the consolidation of the
       Company, Quantum and XNT and the effects of the acquired in process
       research and development have been excluded from the amounts presented

(3)    CASH, CASH EQUIVALENTS AND MARKETABLE SECURITIES

       Cash equivalents are highly liquid investments with original maturities
       of three months or less. Marketable securities are highly liquid
       investment grade securities with original maturities of greater than
       three months. Investments purchased to be held for indefinite periods of
       time and not intended at the time of purchase to be held-to-maturity are
       classified as available-for-sale and reported at fair market value. At
       December 27, 1997, December 31, 1998 and March 31, 1999, the Company has
       classified all investments as available-for-sale. The unrealized gain on
       available-for-sale securities at December 31, 1998 was approximately
       $107,000, which has been recorded as other comprehensive income in
       stockholders' equity. During fiscal years 1997 and 1998, and during the
       three months ended March 28, 1998 and March 31, 1999, the Company
       realized net gains of $55,000, $3,000, $0 and $0, respectively, using the
       specific-identification method. No gains were realized during 1996. The
       Company's investments include time deposits, commercial paper, bankers'
       acceptances and corporate, state municipality and U.S. government debt
       and equity securities.

       In March 1999, the Company entered into an arrangement with a leasing
       company to enable the Company's customers to finance the purchase of
       Excel equipment. Under the terms of this arrangement, as amended, the
       Company has a recourse obligation in the amount of the greater of
       $1,000,000 or 20% of the aggregate net book value of annual equipment
       sales financed. In addition,

                                      F-14

<PAGE>



       the Company has a 100% recourse obligation for contracts funded for
       customers with certain credit ratings, as determined by the leasing
       company.

       During the first quarter of 1999, the Company sold approximately $7.9
       million of equipment under this agreement to the leasing company. The
       leasing company leased this equipment to certain customers. 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.

</TABLE>

       At December 31, 1998, the Company had net operating loss carryforwards
       for federal and state income tax purposes of approximately $17,034,000.
       The net operating loss carryforwards expire through 2018 and are subject
       to review and possible adjustment by the Internal Revenue Service (IRS).
       The Tax Reform Act of 1986 contains provisions that may limit the net
       operating loss carryforwards available to be used in any given year in
       the event of significant changes in ownership interest, as defined.

              the merger on May 10, 1999, all outstanding shares of redeemable
              convertible preferred stock plus cumulative dividends were
              converted to approximately 822,000 shares of Excel common stock.

(11)   STOCK OPTION PLANS

       Stock options are generally exercisable within 10 years of the original
       date of grant and vest over a period of up to five years from the date of
       grant. 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.

       The Company has the following stock option and stock purchase plans:

       (a)    STOCK OPTION PROGRAM

              The Company has granted nonqualified stock options to purchase
              shares of its common stock at exercise prices generally determined
              to be at fair market value by the Company's Board of Directors on
              the date of grant. In November 1997, this program was terminated.
              There are 9,472,545 options outstanding under this program as of
              December 31, 1998.

       (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

       (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. During 1997 and 1998, the Company granted a total of 120,000
              options under the Director Option Plan, of which 100,000 options
              were outstanding at December 31, 1998.

       (d)    1996 RASCOM STOCK OPTION PLAN

              In connection with the merger of RAScom and Excel, the Company
              adopted RAScom's 1996 Stock Option Plan. Under the terms of the
              Company's 1996 Stock Option Plan (1996 Plan), incentive stock
              options were granted to employees of RAScom, Inc. During 1997 and
              1998 and the three month ended March 31, 1999, the Company granted
              45,159, 47,250 and 39,920 options, respectively, of which 90,203
              options were outstanding as of December 31, 1998. The Company does
              not intend to issue additional grants under this Plan.

       (f)    FAIR VALUE OF STOCK OPTIONS

              Statement of Financial Accounting Standards (SFAS) No. 123,
              ACCOUNTING FOR STOCK-BASED COMPENSATION, requires the measurement
              of the fair value of stock options to be included in the statement
              of income or disclosed in the notes to financial statements. The
              Company has determined that it will continue to account for
              stock-based compensation for employees under Accounting Principles
              Board Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES,
              and elect the disclosure-only alternative under SFAS No. 123.

              Had compensation cost for the Company's option plans been
              determined based on the fair value at the grant dates, as
              prescribed in SFAS No. 123, the Company's net income would have
              been as follows:

         (a)  MERGER AGREEMENT WITH LUCENT TECHNOLOGIES, INC.

              On August 17, 1999, the Company entered into an agreement with
              Lucent Technologies, Inc ("Lucent") whereby the Company is to be
              acquired by Lucent. Under the terms of the merger agreement, each
              share of Excel will be converted into .558 shares of Lucent.
              This transaction would value each share of Excel common stock at
              approximately $37.

              It is anticipated that this merger will be accounted for as a
              pooling of interests and be completed during the fourth quarter.
              The merger is subject to the approval of the Company's
              shareholders, the effectiveness of Securities and Exchange
              Commission filings, Hart-Scott-Rodino antitrust regulatory
              clearance and other customary conditions. The Company expects to
              incur a charge for one-time merger related expenses of
              approximately $9.5 million during the period in which the merger
              is completed.

         (b)  RECENT ACQUISITION

              In July 1999, the Company completed the acquisition of certain
              technology and assets. This technology included host-computer
              based software applications for the Excel programmable switching
              platforms. Consideration included cash payments of approximately
              $4.0 million, the issuance of promissory notes totaling
              approximately $7.4 million and the assumption of certain
              liabilities. Such notes bear interest of 8% per annum and are
              payable at various dates through January 2001. The Company will
              account for this acquisition as a purchase transaction and,
              accordingly, will allocate the purchase price to the fair value of
              assets acquired and liabilities assumed. Principal assets acquired
              include contract rights, property and equipment, existing
              technology and in-process research and development for which the
              Company will record a one-time charge in the third quarter. The
              Company is in the process of completing a valuation of the assets
              acquired in this transaction for purposes of purchase accounting
              with the assistance of an independent valuation consultant.
