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 of America. 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, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of September 30, 2000 and 1999, 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 of America. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule listed in the Table of Contents 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. The schedule is the responsibility of the Plan's management. Such schedule has been subjected to the auditing procedures applied in our audit of the basic 2000 financial statements and, in our opinion, is fairly stated in all material respects when considered in relation to the basic financial statements taken as a whole.

DESCRIPTION OF THE PLAN The following description of the Mesa Air Group, Inc. 401(k) Plan (the "Plan") provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. a. General - The Plan is a defined contribution plan sponsored by Mesa Air Group, Inc. (the "Employer"). Under the provisions of the Plan, as amended, union and nonunion employees of the Employer and its affiliates, other than West Air Holding, Inc. and CC Air, Inc., who are 21 years of age and have completed one year of service are eligible to participate. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). Employees may elect to allocate their contributions and their share of Employer contributions to various investment options as specified in the Plan. b. Contributions and Vesting - Various accounts have been established for pre-tax voluntary employee contributions, forfeitures and earnings or losses from Plan assets. Accounts in use and their major provisions are as follows: - Employee Contribution Account - Salary Reduction Contribution Accounts have been established for pre-tax voluntary employee contributions ranging from 1 percent to 15 percent of employee compensation up to the annual deferral limit set by the Internal Revenue Code ("IRC"). All such balances are fully vested. - Employer Contributions Account - Contributions to this account are at the discretion of the Employer. Employer contributions currently match 50 percent of participant contributions up to 10 percent of compensation. In addition, the Employer may contribute to the Plan a discretionary amount as determined by the Employer's Board of Directors as a profit sharing contribution. Employer discretionary contributions are allocated to active participants based upon the ratio that each participant's annual compensation bears to the total of all active participants' annual compensation. Forfeitures are reallocated as additional Employer matching contributions. - Employees are 20 percent vested in Employer contribution accounts after 3 years of service. Vesting subsequently increases 20 percent per year until the participant becomes fully vested. Participants also become fully vested upon becoming disabled, reaching age 65, or death if still employed by Mesa Air Group, Inc. c. Participant Accounts - Each participant's account is credited with the participant's contribution, the employer's matching contribution, and an allocation of the employer's discretionary contribution and the Plan's earnings. The Employer's discretionary contribution is allocated to each participant in the ratio that each such participant's basic contribution (up to 4 percent) for the Plan year bears to all basic contributions of all participants. The Plan's earnings are allocated to each participant in the ratio that each such participant's account balance for each fund bears to the total balance in that fund of all eligible participants on the date of each such allocation. -4- 8 d. Investment Options - As of September 30, 2000, participants may direct employee contributions in 1 percent increments in any of six investment options offered by Putnam and a fund that invests in Mesa Air Group, Inc. common stock. e. Payment of benefits is available upon retirement, death, disability or termination. Benefits are paid in the form of a lump-sum payment, installments or a nontransferable annuity. Participants may withdraw amounts from their account as set forth in the provisions of the Plan document for certain hardship situations. f. Participant Loans - Participants may borrow from their accounts a minimum of $1,000 and a maximum equal to the lesser of $50,000, reduced by the highest outstanding loan balance during the preceding twelve months, or 50 percent of their vested benefits. Loan terms range from one through five years unless funds are used to purchase a primary residence. The loans are secured by the balance in the participant's account. The loans accrue interest at a fixed rate determined by the Plan Administrator. The rate will be comparable to those currently available from commercial institutions. Interest rates range from 7 percent to 9.25 percent. Principal and interest are payable through monthly payroll deductions. g. Plan Termination - Although it has not expressed any intent to do so, the Employer has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to prior approval of the Internal Revenue Service and the Department of Labor. Upon complete discontinuance of contributions under the Plan, all employees' rights are non-forfeitable. h. Tax Status - The Internal Revenue Service has determined and informed the Employer by letter dated December 23, 1998 that the Plan and related trust are designed in accordance with applicable sections of the IRC. The Plan has been amended since receiving the determination letter; however, the Plan Administrator believes the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Plan prepares its financial statements in accordance with accounting principles generally accepted in the United States of America. Significant accounting policies are as follows: a. Basis of Accounting - The accompanying financial statements of the Plan have been prepared in accordance with accounting principles generally accepted in the United States of America using the accrual basis of accounting. b. 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 the reported amounts of net assets available for benefits and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. c. Investment Valuation - Mutual fund investments and Mesa Airlines Group, Inc. common stock are stated at market value based upon quoted market prices as determined by the Plan Trustee. Participant loans are valued at cost, which approximates fair value. Purchases and sales are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. d. Administrative Expenses - All administrative expenses are paid by the Employer. e. Payment of Benefits - Benefits are recorded when paid. -5- 9 3.
