REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Plan Administrator and Trustee of the

MSC Industrial Direct 401(k) Plan

We have audited the accompanying statements of net assets available for benefits of the MSC Industrial Direct 401(k) Plan (the “Plan”) as of December 31, 2007 and 2006, and the related statement of changes in net assets available for benefits for the year ended December 31, 2007. 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 in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Plan’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also 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.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2007 and 2006, and the changes in its net assets available for benefits for the year ended December 31, 2007, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 2 to the financial statements, in 2006 the Plan adopted FSP AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare and Pension Plans.

Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets held at end of year as of December 31, 2007, is presented for purposes of additional analysis and is not a required part of the 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. This supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole.

1.      DESCRIPTION OF PLAN

The following description of the MSC Industrial Direct 401(k) Plan, as amended (the “Plan”) provides only general information. Participants should refer to the plan document for a more complete description of the Plan’s provisions.

General

The Plan is a defined contribution plan, covering all Employees (as defined in the Plan) of participating employers (other than Employees who are non resident aliens with no earned income from a participating employer which constitutes income from services within the United States and Employees covered by a collective bargaining agreement) who meet certain age and service requirements of the Plan. It is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”). MSC Industrial Direct Co., Inc. (the “Company”) is responsible for the administration of the Plan. T. Rowe Price Trust Company is the Plan Trustee and T. Rowe Price Retirement Plan Services, Inc. is the record keeper for the Plan.

Upon the Company’s acquisition of J&L America, Inc., d/b/a J&L Industrial Supply (“J&L”), in June 2006, former J&L employees became eligible to participate in the Plan. Accordingly, rollover contributions of $1,348,429 and loan balances of $257,988 were received into the Plan during the year ended December 31, 2006.

Eligibility

An Employee is eligible for participation in the Plan on the first day of the month following one full calendar month of service, or anytime thereafter, and must be at least eighteen years of age.  Both full-time and part-time employees are eligible to join the Plan.

Contributions and Vesting

Participants may elect to contribute between 1% and 40% of their annual compensation, as defined in the Plan. The maximum annual contribution a participant could make into the Plan, as established by the Internal Revenue Code (the “Code”), was $15,500 ($20,500 for participants eligible to make catch-up contributions) during 2007. Participants may also contribute amounts representing distributions from other qualifying plans. Participants are immediately vested in their pre-tax and rollover contributions.

The Employer (as defined in the Plan) may make a discretionary matching contribution to eligible participants.  The Employer determined to make, for 2007, a matching contribution of 50% of the first 6% (an increase from 4% as of January 1, 2007) of a participant’s pre-tax contribution.  The Employer may also make a discretionary profit sharing contribution to eligible participants to be allocated in the same ratio as each eligible participant’s compensation bears to the total of such compensation of all eligible participants. In general, participants must have completed 1,000 hours of service during a calendar year and be employed on the last day of the Plan year to be eligible to share in the allocation of any profit sharing employer contributions. Participants vest in Employer contributions as follows:

7

MSC INDUSTRIAL DIRECT 401(K) PLAN

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007 (continued)

In addition, 100% vesting occurs upon termination of the Plan.

In 2007, the Employer’s discretionary matching contributions were $3,603,237. This included the payment of the December 31, 2007 contribution receivable and the application of forfeitures accumulated in 2007 and previous Plan years of $233,010. There were no discretionary profit sharing contributions in 2007.

Participant Accounts

Individual accounts are maintained for each participant in the Plan. Each participant’s account is credited with the participant’s contributions and allocations of (a) the Company’s contributions and (b) earnings and losses from applicable investment performance, and, if not paid by the Employer, administrative expenses.

Forfeitures

Forfeited balances of terminated participants’ non-vested employer contributions are used to reduce future employer discretionary matching contributions. Forfeitures accumulated during 2007 and previous Plan years were $232,487, with a forfeiture balance of $11,911 as of December 31, 2007.

Participant Loans

The Plan has a loan provision, which allows participants to borrow from the Plan. The minimum loan is $1,000, and the maximum loan is generally 50% of a participant’s total vested account balance, not to exceed $50,000. The interest rate is established by the prime rate plus one percent. Interest rates on outstanding loans as of December 31, 2007 ranged from 5.00% to 10.50%.  Interest paid by a participant on an outstanding loan is paid directly into the participant’s account. Principal and interest is paid ratably through payroll deductions. The repayment period cannot exceed five years unless the loan is used to acquire a participant’s principal residence, in which case the repayment period cannot exceed ten years. A participant can have a maximum of two loans outstanding from the Plan at any given time.

DECEMBER 31, 2007 (continued)

In-Service Withdrawals

The Plan permits a participant to withdraw participant pre-tax, vested discretionary matching and vested discretionary profit sharing contributions to the extent necessary to satisfy the participant’s hardship (as defined in the Plan). In addition, the Plan permits participants who have attained age 59-1/2 to make in-service withdrawals from the Plan.

Payment of Benefits

On termination of service due to death, disability, retirement or for any other reason, if the participant’s vested balance exceeds $5,000, a participant (beneficiary upon death) may elect to receive either a lump-sum distribution equal to the value of the participant’s vested interest in his or her account or installments over a fixed period. If a participant’s vested account balance is less than or equal to $5,000, the participant’s vested account balance will be paid in a lump-sum distribution. If the amount of such mandatory distribution is more than $1,000 and the participant does not elect to have such distribution directly rolled over into an IRA or other eligible retirement plan or paid directly to him or her, such amount will be directly rolled over into an IRA established by the Plan administrator in the participant’s name.

Plan Expenses

Expenses for record keeping, investment and other costs are generally paid by the Plan. Accounting fees are generally paid by the Company.

Amendment and Restatement

On December 26, 2006, the Plan was amended and restated, generally effective January 1, 2006, utilizing a prototype document sponsored by AccuDraft, Inc.  As part of such restatement, the Plan was amended to, among other things, comply with the new final regulations issued by the Treasury Department under Sections 401(k) and 401(m) of the Internal Revenue Code of 1986, as amended, and to change, effective January 1, 2007, the definition of disability to reflect the definition of disability used by the Company’s long-term disability plan.

2.      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting

The accounting records and financial statements of the Plan are prepared on the accrual basis in accordance with accounting principles generally accepted in the United States and are based upon data provided by the record keeper and/or custodian, adjusted for accruals for contributions receivable and excess contribution payments due to participants based on the results of ERISA limit testing.

Recent Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standard No. 157, “Fair Value Measurements” (“SFAS 157”), which establishes a framework for measuring fair value in accordance with generally accepted accounting principles and expands disclosure about fair value measurements. The provisions of SFAS 157 are effective for financial statements issued with fiscal years beginning after November 15, 2007. The Plan’s management does not believe that the adoption of SFAS 157 will have a material impact on the Plan’s financial statements.

In December 2005, the FASB issued FASB Staff Position AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare and Pension Plans (the “FSP”).   The FSP defines the circumstances in which an investment contract is considered fully benefit-responsive and provides certain reporting and disclosure requirements for fully benefit-responsive investment contracts in defined contribution health and welfare and pension plans. The financial statement presentation and disclosure provisions of the FSP were effective for financial statements issued for annual periods ending after December 15, 2006.  The Plan adopted the provisions of the FSP at December 31, 2006.

As required by the FSP, investments in the accompanying Statements of Net Assets Available for Benefits include fully benefit-responsive investment contracts recognized at fair value.  AICPA Statement of Position 94-4-1, Reporting of Investment Contracts Held by Health and Welfare Benefit Plans and Defined Contribution Pension Plans, as amended, requires fully benefit-responsive investment contracts to be reported at fair value in the Plan’s Statement of Net Assets Available for Benefits with a corresponding adjustment to reflect these investments at contract value. Adoption of the FSP had no effect on the Statement of Changes in Net Assets Available for Benefits for any period presented.

MSC INDUSTRIAL DIRECT 401(K) PLAN

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007 (continued)

Investments

The Plan’s investments are stated at fair value.  The shares of registered Investment Companies are valued at quoted market prices, which represent the net asset values of shares held by the Plan at year-end.  Common Collective Trusts are valued at quoted redemption values on the last business day of the Plan year.

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

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rates, and market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

The fair market value of the shares of Common Stock will be equal to the closing price of the Common Stock as reported on the principal national securities exchange on which such shares are traded on the date of valuation.

The Stable Value Fund (the “Fund”) is a Common Collective Trust which invests principally in guaranteed investment contracts issued by insurance companies, investment contracts issued by banks, synthetic investment contracts issued by banks, insurance companies and other related securities. These investment contracts are intended to maximize current income consistent with the maintenance of principal while permitting participant-initiated benefit-responsive withdrawals for certain events.  Because the guaranteed investment contracts are fully benefit-responsive, contract value is the relevant measurement attribute for that portion of the net assets available for benefits attributable to the guaranteed investment contracts. Contract value, as reported to the Plan, is cost plus accrued income minus redemptions. Contract value is the amount participants would receive if they were to initiate permitted withdrawals under the terms of the Plan.

Certain events limit the ability of the Fund to transact at contract value with the issuers of its investment contracts. Specifically, any event outside the normal operation of the Fund which causes a withdrawal from an investment contract may result in a negative market value adjustment with respect to such withdrawals. Such events include, but are not limited to, the following: (1) partial or complete legal termination of the trust, (2) tax disqualification of the trust or a participant, or (3) certain trust amendments if issuers’ consent is not obtained. As of December 31, 2007, the occurrence of an event outside the normal operation of the Fund which would cause a withdrawal from an investment contract is not considered to be probable.

Benefit Payments

Benefits are recorded when paid.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates.

3.      INVESTMENTS

The fair value of individual investments that represent 5% or more of the Plan’s net assets at December 31, 2007 and 2006 are as follows:

*   Does not represent five percent or more of the Plan net assets at December 31, 2006.

** Does not represent five percent or more of the Plan net assets at December 31, 2007.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2007 (continued)

During the Plan year ended December 31, 2007, net appreciation (depreciation) in fair value of investments was as follows:

4.      INVESTMENT OPTIONS

Participants may allocate their contributions into the Plan among the following 20 options:

1)              MSC Industrial Direct Co., Inc. Class A Common Stock— The Plan Trustee will be permitted to acquire, with amounts directed by participants to be invested in the MSC Industrial Direct Co., Inc. Stock Fund, shares of Class A Common Stock (“Common Stock”) directly from the Company.

The Plan Trustee may acquire (sell) shares of Common Stock by purchasing (selling) such shares on the principal national securities exchange on which shares of Common Stock are traded on that date, and the cost of such shares will be the weighted average purchase price (weighted average sale price) paid by the Plan Trustee during a day. The price includes commissions incurred in the purchase or sale. Alternatively, the Plan Trustee may acquire shares of Common Stock directly from the Company. If acquired directly from the Company, the cost of the shares of Common Stock will be the average of the high and low of the Common Stock as traded on the principal national securities exchange on which such shares are traded on the date issued by the Company.  All of the shares of Common Stock purchased (sold) by the Plan Trustee in the Plan year were traded through the principal national securities exchange.

The Plan Trustee may acquire shares of Common Stock in a single purchase or over time, as they determine in their sole discretion.

If circumstances so require, the Plan Trustee may suspend the purchase and sale of shares of Common Stock. Such suspension will last until the Plan Trustee determines that the circumstances causing the suspension have ceased to exist.

The value of the MSC Industrial Direct Co., Inc. Stock Fund is subject to fluctuation in the market price of the shares of Common Stock. There is no guarantee of investment performance. Likewise, there is no guarantee that the Company will pay dividends in the future.
