INDEPENDENT AUDITORS' REPORT


Administrative Committee
CenturyTel, Inc. Union Group Incentive Plan:

We have audited the accompanying statements of net assets available for benefits
of the CenturyTel, Inc. Union Group Incentive Plan (the "Plan") as of December
31, 2000 and 1999, 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 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 December 31,
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 audit was 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. This schedule is the responsibility of the Plan's management. The
supplemental 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.

CENTURYTEL, INC. UNION GROUP INCENTIVE PLAN

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 2000 AND 1999
-------------------------------------------------------------------------------


1.    DESCRIPTION OF THE PLAN

      The following brief description of the CenturyTel, Inc. Union Group
      Incentive Plan, formerly the CenturyTel, Inc. Group Incentive Plan (the
      "Plan"), is provided for general information purposes only. Participants
      should refer to the plan document for more complete information.

      General - The Plan is a defined contribution plan covering eligible
      employees of CenturyTel, Inc. and its subsidiaries (the "Company").
      Through August 31, 2000, eligible employees are those employees covered by
      certain collective bargaining agreements and who have completed 1,000
      hours of service as defined by the Plan. Thereafter, eligible employees
      are those employees covered by certain collective bargaining agreements.
      Participants may enroll during the first available enrollment period
      subsequent to their first day of employment. The Plan is subject to the
      provisions of the Employee Retirement Income Security Act of 1974
      ("ERISA").

      Participant and Employer Contributions - Through August 31, 2000,
      participants were required to make pre-tax contributions of at least 1% of
      their compensation and may elect to make additional pre-tax contributions
      up to 15% for a maximum pre-tax contribution of 16% of annual
      compensation. The Company made matching contributions for each participant
      equal to 55% of the participant's pre-tax contributions up to 6% of
      compensation. Subsequent to this date, there is no minimum required
      participant contribution amount and participants may make pre-tax
      contributions up to 16% of their eligible annual compensation. The Company
      makes matching contributions for each participant of either 55% or 66% of
      the participant's pre-tax contributions up to 6%, as defined by the
      applicable collective bargaining agreement. Contributions are subject to
      certain limitations.

      Participant Loans - Participants may borrow from their account balance a
      minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of
      their vested account balance. Loan terms range from one to five years or
      up to fifteen years for the purchase of a primary residence. The loans
      bear interest at a rate equal to the prime rates published in the Wall
      Street Journal on the last day of the previous quarter plus 1% and are
      secured by the balance in the participant's account and an assignment of
      current pay of the participant sufficient to service the loan.

      Investment Options - Participants were allowed to direct contributions to
      any of the following investment options through August 31, 2000:

            HighMark Income Equity Fund
            HighMark Bond Fund
            Union Bank Stable Value Fund
            Dreyfus Index 500 Fund

      As of September 1, 2000, participants may direct contributions to any of
      the following investment options:

            T. Rowe Price Summit Cash Reserves Fund
            PIMCO Total Return Fund
            BGI Asset Allocation Fund
            T. Rowe Price Equity Index 500 Fund
            Janus Fund
            T. Rowe Price Equity Income Fund
            Janus Overseas Fund
            MSDW Institutional Small Company Growth Portfolio Fund
            T. Rowe Price Mid-Cap Growth Fund
            BGI LifePath Income Fund
            BGI LifePath 2010 Fund
            BGI LifePath 2020 Fund
            BGI LifePath 2030 Fund
            BGI LifePath 2040 Fund
            CenturyTel Common Stock

      Participant Accounts - A separate account is maintained for each
      participant, which is credited with the participant's contribution, an
      allocation of the employer's contribution, and Plan earnings. Allocations
      of the employer contributions are based on the participants' deferrals, as
      defined. Plan earnings are allocated based on the investment returns from
      the investment options selected by the participant and the participant's
      account balance. The benefit to which a participant is entitled is based
      on the vested balance of the participant's account.

      Vesting - The employer contributions and the accumulated earnings thereon
      vest to participants as follows:


              Years of Service                        Percentage Vested
              ----------------                        -----------------
                 Less than 1                                   0%
                      1                                       20
                      2                                       40
                      3                                       60
                      4                                       80
                      5                                      100

      In the event of death, disability, or upon reaching age 65, the employer
      contributions and the accumulated earnings thereon become fully vested.
      Participant contributions and the accumulated earnings thereon are fully
      vested at all times.

      Benefits Paid - Participants are entitled to receive benefits upon
      termination of employment for any reason including death, disability, or
      retirement. If the participant's account balance exceeds $5,000, the
      participant may defer payment until a later date. Otherwise, distributions
      are made in a lump sum as soon as administratively feasible. At
      retirement, participants may elect a lump sum payment or periodic
      installments over 5, 10, or 15 years. Participants may also withdraw
      benefits for financial hardship reasons. Such withdrawals are subject to
      the approval of the Administrative Committee.

      Forfeitures - The portion of a participant's account that is not vested
      shall be forfeited at the earlier of the date of distribution of the
      participant's entire vested balance in the plan following the
      participant's termination or the date on which the participant completes a
      full break in service. The forfeiture shall be valued as of the last
      valuation date before the date of the forfeiture. Forfeitures occurring
      during a plan year shall be used first to satisfy any restorations for the
      year and any remaining forfeitures shall be applied to offset future
      employer contributions or pay plan expenses.

      Plan Termination - Although it has not expressed any intention to do so,
      the Company has the right under the Plan to discontinue its contributions
      at any time or to terminate the Plan subject to the provisions of ERISA.
      In the event the Company terminates the Plan or discontinues contributions
      to the Plan, the accounts of all participants will become fully vested.

2.    SIGNIFICANT ACCOUNTING POLICIES

      The following are the significant accounting policies followed by the
      Plan.

      Basis of Accounting - The financial statements of the Plan are prepared
      under the accrual method of accounting.

      Investments Valuation and Income Recognition - Investments in mutual funds
      and employer common stock are stated at fair value based upon quoted
      market prices of the underlying securities. The Plan's investment in
      common/collective trust investments are stated at contract value which
      represents contributions made under the contract, plus earnings, less
      withdrawals. Plan management believes that the contract value approximates
      fair value for the common/collective trust investments. The average yield
      to maturity of the common/collective trust investments was 5.94% as of
      December 31, 1999. There were no valuation reserves as of December 31,
      2000 and 1999. Temporary cash investments are stated at cost, which
      approximates fair value. Purchases and sales of securities are recorded on
      a trade-date basis. Interest income is recorded when earned. Dividends are
      recorded on the ex-dividend date.

      Funding Policy - Participant pre-tax contributions to the Plan are made
      through payroll deductions and are forwarded to the Plan trustee biweekly
      along with the employer contributions.

      Administration Expenses - The Plan provides that the Company may pay
      administrative costs of the Plan. Those costs not paid by the Company are
      paid from Plan assets.

      Use of Estimates - The preparation of the financial statements in
      conformity with accounting principles generally accepted in the United
      States of America requires management to make estimates and assumptions
      that affect reported amounts of net assets and disclosure of contingent
      assets and liabilities at the date of the financial statements and the
      reported amounts of additions and withdrawals during the reporting period.
      Actual results could differ from those estimates.

      Benefits Paid - Benefits are recorded when paid.

3.    INVESTMENTS GREATER THAN 5% OF NET ASSETS

      The following represents individual investments that are greater than 5%
      of the net assets at December 31:

                                                       2000              1999

       PIMCO Total Return Fund                    $ 2,850,197      $         -
       T. Rowe Price Equity Income Fund             7,179,352                -
       T. Rowe Price Equity Index 500 Fund          4,259,037                -
       T. Rowe Price Summit Cash Reserves Fund      4,342,133                -
       HighMark Income Equity Fund                          -       10,607,561
       HighMark Bond Fund                                   -        3,385,621
       Stable Value Fund                                    -        3,990,165



      Net appreciation (depreciation) by investment type for the years ended
      December 31 is as follows:

4.    PLAN ADMINISTRATION

      Effective September 1, 2000, the Plan changed the trustee and recordkeeper
      from Union Bank of California and Merrill Lynch/Howard Johnson to T. Rowe
      Price.

5.    TAX STATUS

      The Plan obtained its latest determination letter dated March 20, 1996 in
      which the Internal Revenue Service stated that the Plan, as then designed,
      was in compliance with the applicable requirements of the Internal Revenue
      Code. The Plan has been amended since receiving the determination letter.
      However, the Plan Administrator believes that the Plan is currently
      designed and being operated in compliance with the applicable requirements
      of the Internal Revenue Code. Accordingly, no provision for income taxes
      has been included in the Plan's financial statements.

6.    PARTY-IN-INTEREST TRANSACTIONS

      Plan assets are invested in mutual funds managed by T. Rowe Price which is
      the trustee of the Plan. These funds are charged administrative expenses
      which are paid by the Company. In addition, the Plan invests in shares of
      Company common stock at the direction of the participants.

7.    CONCENTRATION OF RISK

      The Plan's assets consist of financial instruments including money market
      funds, mutual funds, common/collective funds, and Company common stock.
      These financial instruments may subject the Plan to concentrations of risk
      as, from time to time, cash balances exceed amounts insured by the Federal
      Deposit Insurance Corporation, and investments in mutual funds,
      common/collective funds, and Company stock are subject to changes in
      market values of such investments.
