                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Participants and Plan Administrator of the
EMC Corporation 401(k) Savings Plan

In our opinion, the accompanying statements of assets available for benefits and
the related statements of changes in assets available for benefits present
fairly, in all material respects, the assets available for benefits of the EMC
Corporation 401(k) Savings Plan (the "Plan") at December 31, 2000 and 1999, and
the changes in assets available for benefits for the years then ended in
conformity with accounting principles generally accepted in the United States of
America. These financial statements are the responsibility of the Plan's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these statements in
accordance with auditing standards generally accepted in the United States of
America, which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements but is supplementary information
required by the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. This
supplemental schedule is the responsibility of the Plan's management. The
supplemental schedule has been subjected to the auditing procedures applied in
the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

As discussed in Note 1, the Data General Corporation Savings and Investment Plan
was merged into the Plan on January 1, 2000.

                                 EMC CORPORATION
                       EMC CORPORATION 401(K) SAVINGS PLAN
                          NOTES TO FINANCIAL STATEMENTS


1.       DESCRIPTION OF THE PLAN

         The following description of the EMC Corporation 401(k) Savings Plan
         (the "Plan") provides only general information. Participants should
         refer to the Plan agreement for a more complete description of the
         Plan's provisions.

         GENERAL

         The Plan is a contributory defined contribution plan established
         January 1, 1983 for the purpose of providing an opportunity for
         retirement income and increased savings to the employees of EMC
         Corporation (the "Company") who meet the length of service
         requirements. Plan assets acquired under this Plan as a result of
         contributions, investment income, and other additions to the Plan will
         be administered for the exclusive benefit of the participants and their
         beneficiaries. It is subject to the provisions of the Employee
         Retirement Income Security Act of 1974 ("ERISA").

         CONTRIBUTIONS

         During 2000, participants could elect to contribute an amount not to
         exceed, in the aggregate, between 1% and 17% (19% as of January 1,
         2001) of their compensation on a pretax basis while participating in
         the Plan. Participants may also contribute amounts representing
         distributions from other qualified plans. In any Plan year, the
         Company may contribute to participants' accounts a quarterly matching
         contribution equal to a percentage of the participant's compensation
         contributed to the Plan as determined by the Company's Board of
         directors up to a maximum quarterly matching contribution of $750.
         In addition, discretionary Company profit sharing contributions
         based on different discretionary goals established for separate
         business units within the Company may be made upon a vote of the Board
         of Directors. To be eligible for an allocation of Company quarterly
         matching contributions, a participant must be employed by the Company
         on the last day of the calendar quarter. To be eligible for an
         allocation of discretionary Company profit sharing contributions, a
         participant must have completed at least 1,000 hours of service during
         the Plan year and be employed by the Company on the last day of the
         Plan year. Contributions are subject to certain limitations under the
         Internal Revenue Code of 1986, as amended (the "Code"). During 2000,
         the Company did not make any discretionary profit sharing
         contributions.

         PARTICIPANT ACCOUNTS

         Each participant's account is credited with the participant's
         contribution, the Company's discretionary matching contribution and an
         allocation of the profit sharing contributions and Plan earnings and
         debited with applicable expenses. Allocations are based on participant
         earnings or account balances, as defined. The benefit to which a
         participant is entitled is the benefit that can be provided from the
         participant's vested account.

         VESTING AND FORFEITURE

         Participants are immediately vested 100% in their voluntary
         contributions, rollover contributions, Company discretionary matching
         contributions plus the investment earnings arising from these
         contributions. Company discretionary profit sharing contributions are
         subject to a vesting schedule based on the number of years of
         continuous service as follows:



                                       5




           YEARS OF SERVICE                           VESTED PERCENTAGE

           Less than 1 year                                    0%
           1 year but less than 2                             25%
           2 years but less than 3                            50%
           3 years but less than 4                            75%
           4 years or more                                   100%


         Participants' interest in their accounts shall become 100% vested and
         nonforfeitable without regard to their credited years of service if
         they are employed by the Company on or after age 65, incur a permanent
         and total disability or die while employed by the Company.

         If a participant who is not fully vested terminates employment with the
         Company, the participant shall be entitled to the vested portion of
         their account. The nonvested portion is forfeited and will be applied
         to the payment of Plan expenses.

         INVESTMENT OPTIONS

         Participants elect to invest the contributions to their accounts in
         five percent increments in the following options:

         PAYMENT OF BENEFITS

         Benefits are payable upon normal retirement age (65), death, separation
         from service or proven hardship. Participants who were a Plan member as
         of December 31, 1988 may elect to receive the value of their vested
         interest in his or her account in the form of an installment or in a
         lump-sum distribution. Plan members after such date will receive their
         vested interest in his or her account in a lump-sum distribution. In
         any event, payment of benefits must commence when the participant
         reaches age 70 1/2 or, if later, following the year they terminate
         employment. However, a 5% owner of the CompanY will be required to
         begin receiving minimum distributions from their account by the April 1
         following attainment of age 70 1/2 regardless of whether they have
         terminated employment at that time.

         PARTICIPANT NOTES RECEIVABLE

         Participants may borrow from their fund accounts a minimum of $1,000 up
         to a maximum equal to the lesser of $50,000 or one-half of the
         participant's vested account balance. Loan terms range from 1-5 years
         or up to 10 years for the purchase of a primary residence. The loans
         are secured by the balance in the participant's account and bear
         interest at a rate commensurate with local prevailing rates as
         determined by the Company, as Plan administrator. Interest rates ranged
         from 8.25% - 10.5% for 2000 and 8.75% - 10% for 1999. Principal and
         interest are paid ratably through payroll deductions.

         MERGER INTO PLAN

         On October 12, 1999, the Company acquired Data General Corporation. In
         connection with the acquisition, the Data General Corporation Savings
         and Investment Plan (the "Data General Plan") merged into the Plan on
         January 1, 2000 resulting in the transfer of assets of $223,571,109 and
         the transfer of participant loans of $5,629,136 into the Plan. Former
         participants of the Data General Plan, eligible to participate in the
         Plan, began to participate in the Plan on January 1, 2000.


2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         BASIS OF ACCOUNTING

         The financial statements of the Plan are prepared using the accrual
         method of accounting.

         USE OF ESTIMATES

         The preparation of financial statements in conformity with accounting
         principles generally accepted in the United States of America requires
         the Plan administrator to make estimates and assumptions that affect
         certain reported amounts and disclosures. Accordingly, actual results
         may differ from those estimates.

         INVESTMENT VALUATION AND INCOME RECOGNITION

         Investments are valued at fair value. Investments in shares of mutual
         funds and the common collective trust are valued based on net asset
         value announced by the fund at year-end. The Company's common stock,
         par value $.01 per share ("Common Stock"), is valued at the quoted
         market price on the last business day of the Plan year. Loans to
         participants are valued at cost plus accrued interest, which
         approximates fair value.

         The Plan presents in the statements of changes in assets available for
         plan benefits net appreciation (depreciation) in the fair value of its
         investments which consists of realized gains or losses and unrealized
         appreciation (depreciation) on investments. The cost of investments is
         determined on the average cost basis in calculating realized gains or
         losses.

         Purchases and sales of securities are recorded on a trade-date basis.
         Interest income is recorded on the accrual basis. Dividends are
         recorded on the ex-dividend date.


                                       7


         EXPENSES OF THE PLAN

         Administrative expenses, including legal and participant accounting,
         and other costs of administrating the Plan, and all expenses directly
         relating to the investments are charged to and paid by the Plan unless
         paid by the Company. The Company pays the majority of expenses except
         certain transaction fees.

         TERMINATION OF THE PLAN

         Although it has not expressed any intent to do so, the Company has the
         right to terminate the Plan. The Plan administrator, upon termination,
         shall cause the assets of the Plan to be allocated as described in the
         Plan agreement. In the event of Plan termination, participants will
         become 100% vested in their accounts.

         PAYMENT OF BENEFITS

         Benefits are recorded when paid.


3.       TAX STATUS OF THE PLAN

         The Internal Revenue Service has determined and informed the Plan
         sponsor by a letter dated November 18, 1998 that the Plan and related
         trust are designed in accordance with applicable sections of the Code.
         The Plan has since been amended and a new letter has not been
         requested. Management has asserted the Plan, as amended, and its
         operations have been and continue to be in accordance with all
         applicable provisions of the Code and ERISA. Therefore, no provisions
         for income taxes are required.


4.       RELATED PARTY TRANSACTIONS

         The Plan invests in Common Stock. During the years ended December 31,
         2000 and 1999, the Plan purchased shares of Common Stock having values
         of $12,916,668 and $10,822,030, respectively, and sold shares of Common
         Stock having values of $1,778,738 and $389,052, respectively. The total
         value of shares held of Common Stock was $23,942,128 and $11,468,519 at
         December 31, 2000 and 1999, respectively.

         Certain Plan investments are shares of mutual funds managed by FMR
         Corp. FMR Corp. is a related party to the trustee as defined by the
         Plan and, therefore, these transactions qualify as party-in-interest
         transactions. Fees paid by the Plan for the investment management and
         recordkeeping services amounted to $11,239 for the year ended December
         31, 2000. Loans to participants also qualify as party-in-interest
         transactions.


5.       DIFFERENCES BETWEEN FINANCIAL STATEMENTS AND PRESENTATION OF ASSET
         INFORMATION IN FORM 5500

         As described in Note 1 of these financial statements, the Data General
         Plan was merged into the Plan as of January 1, 2000 and the December
         31, 1999 financial statements of the Plan do not reflect the merger.
         The Form 5500 for the Plan shows the transfer of assets occurring on
         December 31, 1999. The two approaches reflect agreement that the assets
         and participants had moved to the respective recipient plan as of
         January 1, 2000. The only difference concerns whether the transfer in
         from the Data General Plan occurred as of January 1, 2000 or, instead,
         occurred the moment before that - i.e., as of the close of business on
         December 31, 1999.
