Report of independent public accountants

To the Plan Administrator of
LodgeNet Entertainment Corporation 401(k) Plan:

We have audited the accompanying statements of net assets available for benefits of LodgeNet Entertainment Corporation 401(k) Plan as of December 31, 2001 and 2000, and the related statements of changes in net assets available for benefits for the years then ended. 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 auditing standards generally accepted in the 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. 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 financial statements referred to above present fairly, in all material respects, the net assets available for benefits of LodgeNet Entertainment Corporation 401(k) Plan as of December 31, 2001 and 2000, and the changes in net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States.

Our audits were performed 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 of Assets (Held At End of Year) 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.

Notes to financial statements

December 31, 2001 and 2000

1      Description of the Plan

The following is not a comprehensive description of LodgeNet Entertainment Corporation 401(k) Plan (the Plan) and, therefore, does not include all situations and limitations covered by the Plan. Participants should refer to the plan agreement for a more complete description of the Plan's provisions.

General

The Plan is a defined contribution plan covering all employees of LodgeNet Entertainment Corporation (the Company) who have completed 90 days of service and are age 18 or older. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA), as amended.

Plan operations

The Company functions as the plan sponsor and administrator. SunTrust Bank is utilized as trustee and asset custodian of the Plan. Administrative expenses of the Plan are paid by the Company and were approximately $28,900 in 2001 and $32,600 in 2000.

Contributions

The maximum percentage of compensation an employee may contribute to the Plan is 15 percent, with an annual maximum contribution of $10,500, as provided by the Code. Amounts contributed are invested at the discretion of plan participants in any of the 20 investment options as directed by the participant.

The Company makes a discretionary match of participant contributions; in 2001 and 2000 the amount equaled 50 percent of the first 6 percent of each participant's eligible contribution for the plan year.

The Company may make additional discretionary contributions to the Plan. In a year in which the Company chooses to make discretionary contributions, the contributions will be allocated based upon a participant's proportionate share of total compensation for all participants. There were no discretionary contributions in 2001 or 2000.

Vesting

Participants are immediately vested in their contributions plus actual earnings thereon. Vesting in the Company's matching contribution portion of participant accounts plus actual earnings thereon is based on years of service. A participant is 100 percent vested after five years of credited service based on the following percentages:

7

If a participant dies or becomes disabled while still employed by the Company, his or her entire plan account balance becomes 100 percent vested. Forfeitures of the nonvested employer contributions, resulting from participants who withdraw from the Plan, are used to reduce future employer contributions. Forfeitures from participants were approximately $20,300 in 2001 and $28,100 in 2000.

Participant loans

Participants may borrow funds from the Plan up to 50 percent of their vested balance at an interest rate of 1 percent over the prime interest rate. Loans will not be granted in amounts less than $1,000 or greater than $50,000. Loans are evidenced by a promissory note and have a repayment period of up to five years, unless the loan qualifies as a home loan. Interest rates on loans range from 6.0 percent to 9.00 percent and 8.25 percent to 9.75 percent for the years ended December 31, 2001 and 2000.

Distribution of benefits

Upon retirement, death, disability, termination of employment or attainment of age 62, a participant or a participant's beneficiary, in the case of death, may receive the vested portion of the amount credited to the participant's account by a lump-sum payment.

2      Summary of significant accounting policies

Basis of accounting

The financial statements have been prepared on the accrual basis of accounting.

Use of estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires the Company to make estimates and assumptions that affect the reported amounts of net assets available for benefits at the date of the financial statements and the reported amounts of changes in net assets available for benefits during the reporting period. Actual results could differ from those estimates.

Investments

Participants have the opportunity to direct all money allocated to their accounts. Participants have 20 investments from which to choose. A description of each investment is as follows:

Janus Adviser International Fund—Seeks long-term growth of capital by normally investing at least 65% of its total assets in securities of issuers from at least five different countries, excluding the United States.

Janus Adviser Worldwide Fund—Seeks long-term growth of capital in a manner consistent with preservation of capital by investing primarily in common stocks of foreign and domestic issuers.

STI Classic International Equity Index—Seeks to provide investment results that correspond to the aggregate price of the securities included in the Morgan Stanley EAFE Index.

STI Classic Life Vision Growth & Income Fund—Seeks to provide long-term capital appreciation, with current income as a secondary objective.

STI Classic Life Vision Moderate Growth—Seeks both capital appreciation and current income.

LodgeNet Entertainment Corporation common stock—Invests in LodgeNet Entertainment Corporation common stock. Limited to 10 percent of contributions made.

Investments are recorded at fair value as determined by SunTrust Bank by reference to quoted market prices as of December 31, 2001 and 2000. Investment income includes realized gains and losses, unrealized appreciation and depreciation, dividends and interest income. Realized gains and losses on the sale of investments are calculated based on the cost of the investments sold. Unrealized appreciation and depreciation of investments represent the change in market value of investments from the historical cost of the investment. Plan investment income is allocated to plan participants based on their pro rata account balances.

The Plan provides for investment securities that, in general, are exposed to various risks, such as interest rate, credit and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statements of net assets available for benefits.

Investments are valued at market value as reported by the asset custodian as of December 31, 2001 and 2000, based on quoted market prices of investments held by the funds.

3      Investments

The following presents investments that represent 5 percent or more of the Plan's net assets:

4      Tax status

The Internal Revenue Service has determined and informed the Company by a letter dated February 14, 1995, that the Plan is designed in accordance with applicable sections of the Internal Revenue Code (the IRC). The Plan has been amended since receiving the determination letter; however, the plan administrator and the Plan's tax counsel believe that the Plan document is in compliance with the applicable requirements of the IRC. The plan sponsor is committed to taking any action necessary to maintain the Plan's qualified status.

5      Plan termination

Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of the Plan's termination, participants will become 100 percent vested in their accounts.

6      Asset transfer

In January 2001, the Plan's net assets were transferred from Nationwide Life Insurance Company (Nationwide) and Charles Schwab Retirement Plan Services to SunTrust Bank. In addition, all trustee and plan recordkeeping administration duties were transferred to SunTrust Bank. Upon termination of the arrangement with Nationwide, a liquidation charge of approximately $236,000 was paid by the Company on behalf of the Plan.

7      Party-in-interest transactions

Certain transactions with participants, the plan sponsor, the custodian and the trustees are considered party-in-interest transactions. These transactions qualify as exempt party-in-interest transactions.
