                          Independent Auditors' Report



The Board of Directors
CenturyTel, Inc.:

We have audited the accompanying statements of net assets available for benefits
of CenturyTel Security Systems, Inc. 401 (k) Plan and Trust as of December 31,
2001 and 2000, and the related statement of changes in net assets available for
benefits for the year ended December 31, 2001. 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, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of CenturyTel
Security Systems, Inc. 401(k) Plan and Trust as of December 31, 2001 and 2000,
and the changes in net assets available for benefits for the year ended December
31, 2001, in conformity with accounting principles generally accepted in the
United States of America.

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 has been subjected to the auditing procedures applied in
the audit 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)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PROVISIONS OF THE PLAN

      Basis of Presentation

      The CenturyTel Security Systems Inc., 401(k) Plan and Trust (the Plan) was
      established on June 1, 1997. The accompanying financial statements of the
      Plan have been prepared on the accrual basis of accounting and present the
      net assets available for benefits and changes in net assets available for
      benefits. The Plan has made estimates in preparing the accompanying
      financial statements in accordance with accounting principles generally
      accepted in the United States of America. Actual results could differ from
      those estimates.

      The assets of the Plan are invested by the Trustee in various investment
      programs (funds) which are described in Note 2.

      The following description of the Plan provides only general information.
      Participants should refer to the Plan Document for a more complete
      description of the Plan's provisions.

      Participation

      Participation in the Plan is available to each employee of CenturyTel
      Security Systems, Inc. (the Company), other than those who are classified
      as temporary employees or employees covered under a collective bargaining
      agreement.

      In order to participate in the Plan, an employee must execute a Salary
      Deferral Agreement with the Company. In the Salary Deferral Agreement,
      which is executed on-line or by telephone, an employee agrees to a
      deferral of between one percent and sixteen percent of compensation. The
      percentage of compensation a participant elects to defer applies to the
      participant's W-2 earnings. The amount of compensation deferred by each
      participant is credited to an account (Elective Deferral Account)
      maintained for each participant by the Trustee. The Elective Deferral
      Account is self-directed.

      The Board of Directors of the Company may, at its discretion, elect at the
      end of each year to contribute an additional amount to participants'
      accounts (Additional Match Account). No additional match was made during
      2001.

      An employee is permitted to transfer to the Plan as a contribution his
      interest in another plan qualified under the Internal Revenue Code, as
      amended (the Code). Such contribution must qualify as a "rollover"
      contribution described in Section 402(c) or 408 (d)(3) of the Code. Such a
      rollover will be credited to a rollover account on behalf of the
      participant (the Rollover/Transfer Account).

      The interest of a participant in his Elective Deferral Account, his
      Rollover/Transfer Account and his Additional Match Account is fully vested
      and non-forfeitable at all times.

      Reports to Participants

      All participants are furnished with quarterly statements which set forth
      the status of their accounts in the Plan.

      Distributions

      If the employment of a participant with the employer ceases because of
      death, retirement, disability, termination of employment or for any other
      reason, the participant's entire interest in the Plan may be distributed
      to him or to his beneficiary in a lump sum. If the participant dies
      without designating a beneficiary, his beneficiary shall be, in the order
      listed, (i) his spouse, (ii) his children, or (iii) his estate.

      Withdrawals

      A participant who is an employee and over age 59 1/2 may make withdrawals
      from his vested accounts prior to meeting normal distribution
      requirements. In addition, a hardship withdrawal may be made from an
      Elective Deferral Account or a Rollover/Transfer Account only as a result
      of financial hardship related to unreimbursable educational expenses,
      medical expenses which are not reimbursable by insurance, the need to pay
      for the funeral expenses of a family member, the purchase of a principal
      residence of the Participant, or the prevention of eviction or foreclosure
      from the Participant's principal residence. The determination of the
      existence of a financial hardship and the amount required to be
      distributed to meet the need created by the hardship shall be made
      uniformly and without discrimination at the sole discretion of the Plan
      Administrator.

      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
      change, suspend or terminate the Plan subject to the provisions of the
      Employee Retirement Income Security Act of 1974.

      Loans to Participants

      The Plan has a provision whereby a participant can borrow from his
      Elective Deferral Account or Rollover/Transfer Account. The maximum loan
      is 50% of the account balance, up to $50,000. The loans are repaid through
      payroll deductions and the interest rate is the prime rate published in
      the Wall Street Journal for the last business day of the previous quarter
      plus 1%. The loan repayment period may not exceed five years except for
      loans for the purchase of the participant's principal residence which may
      be for any period not to exceed fifteen years.

      Trustee

      The Trustee of the Plan, as of December 31, 2001, was T. Rowe Price Trust
      Company (T. Rowe Price). The Board of Directors of the Company may remove
      the Trustee and appoint a successor trustee. The Company and the Trustee
      have entered into a Trust Agreement which provides for the establishment
      of a Trust for the purpose of holding and investing the contributions to
      the Trust pursuant to the provisions of the Plan.

      Administration

      The Company has appointed a committee to administer the Plan. The
      individuals who administer the Plan serve at the discretion of the Board
      of Directors of the Company and may be removed by the Board of Directors
      at any time. The administrative costs of the Plan are paid by the Company.

      Investment Valuation and Income Recognition

      Investments in CenturyTel Common Stock are valued at the closing market
      price on December 31, 2001. Other investments in the funds, which consist
      of shares of mutual funds, are valued by the Trustee based on the market
      value at year-end of the underlying assets of each fund. Purchases and
      sales of securities are recorded on a trade date basis. Interest income is
      recorded on the accrual basis.

      A participant may instruct that his contribution be allocated among the
      various funds. A participant may change his investment allocation
      instructions and his contribution percentage at any time.

(3)   INCOME TAXES

      The Plan and related trust were designed to meet the necessary
      requirements of Internal Revenue Code Section 401(a) and, accordingly, the
      trust underlying the Plan is exempt from income taxation pursuant to
      Internal Revenue Code Section 501(a). A favorable determination letter
      from the Internal Revenue Service has not been obtained for the Plan as
      currently amended and restated. A request for such was filed on February
      28, 2002. However, the Plan administrator believes that the Plan is
      designed and is currently being operated in compliance with the applicable
      provisions of the Internal Revenue Code.

(4)   RELATED PARTY TRANSACTIONS

      Certain Plan investments are shares of mutual funds managed by T. Rowe
      Price, Janus Capital Corporation (Janus), Barclays Global Investors
      Funds, Inc.(Barclays), Morgan Stanley Dean Witter Investment  Management
      Inc.(Morgan Stanley) or Pacific Investment Management Company (PIMCO).
      T. Rowe Price is the Trustee as defined by the Plan.  Therefore, T. Rowe
      Price, Janus, Barclays, Morgan Stanley and PIMCO qualify as  parties-in-
      interest. Fees paid by the Company to T. Rowe Price for trustee, record
      keeping and other services amounted to $7,160 for the year ended December
      31, 2001.

(5)   CONCENTRATION OF INVESTMENTS

      Substantially all of the assets available for benefits were invested in
      mutual funds managed by T. Rowe Price, Janus, Barclays, Morgan Stanley or
      PIMCO. The remaining assest available for benefits were invested in
      CenturyTel Common Stock.

(6)   SUBSEQUENT EVENTS

      On January 1, 2002, the individual participant maximum elective salary
      deferral was increased to twenty-five percent from sixteen percent;
      however, the total amount contributed to the Plan cannot exceed $11,000
      for 2002.

      Effective June 3, 2002, participants age 50 years or older are allowed to
      make an additional contribution to the Plan each year in excess of the
      otherwise prescribed limits. The amount of the allowable additional
      contribution for a participant in 2002 is $1,000; this amount will
      increase by $1,000 each year to a maximum of $5,000 in 2006 (which will
      thereafter be adjusted for inflation).
