Dear Mark:

                       EMPLOYMENT AND SEVERANCE AGREEMENT

The Times Mirror Company ("Times Mirror") has entered into an agreement dated as
of March 13, 2000 with Tribune Company ("Tribune") under which Times Mirror will
merge into Tribune (the "Merger Agreement") and on the date of the completion of
the merger ("Effective Date"), Times Mirror will cease to exist as a corporate
entity. This agreement (the "Agreement"), which is effective as of the date
hereof, will set forth (i) the terms of your employment as approved by the
Executive Subcommittee of the Compensation Committee at its meeting on March 2,
2000 and later approved by the Board of Directors at its meeting on March 11,
2000; (ii) the enhanced severance benefits that you will receive under the terms
of the Severance Attachment to this Agreement; (iii) certain compensation and
benefits as set forth in the Certain Compensation and Benefits attachment; and
(iv) certain employee benefits to which you are entitled, including a special
retirement arrangement, as set forth in the Certain Employee Benefits
attachment.


1. Continued Service.

    (a) Subject to the provisions of paragraph 1 (d) of this Agreement, Times
        Mirror agrees to continue your employment until the Effective Date and
        you agree to remain in your present position on the terms contained in
        this Agreement. Your active employment status will not be terminated
        prior to the Effective Date for any reason other than as set forth in
        paragraph 1 (d), and you will remain an employee until, and termination
        will become effective on, the day after the Effective Date to enable you
        to receive the benefits set forth in this Agreement.

    (b) This Agreement and all the obligations of Times Mirror to you hereunder
        will terminate if and at such time as Times Mirror informs you in
        writing that the merger with Tribune will not take place. In such event,
        you will remain in the employ of Times Mirror until your successor is
        designated by the Board of Directors of Times Mirror, under those terms
        and conditions which presently apply

        to your employment. Since you were informed prior to the merger that
        your employment will be terminated as of the merger, you shall receive
        the benefits set forth in this Agreement even in the event that it is
        determined at a later date that the merger will not occur.

    (c) Upon the Effective Date, this Agreement and all the obligations of Times
        Mirror hereunder, shall be assigned to and assumed by Tribune.

    (d) All rights and obligations of any party to this Agreement, including but
        not limited to, those set forth in any Attachment to this Agreement
        (except to the extent you are fully vested in or otherwise entitled to
        any employee benefit after the termination of your employment in
        accordance with the terms of the relevant benefit plan), will terminate
        immediately in the event (i) you voluntarily resign from your position
        prior to the Effective Date for any reason or (ii) you are terminated
        for cause. For the purpose of this Agreement, "cause" shall mean any
        material breach of your obligations to Times Mirror or Tribune, the
        commission by you of any criminal act (except for traffic or any other
        minor offences), or any act of dishonesty or abuse of office.

2. Duties and Benefits.

    (a) While you are employed under the terms of this Agreement:

        (i) You will perform those functions, duties and responsibilities which
            are assigned to you;

        (ii) There shall be no change in your salary or bonus opportunity and no
            change in the employee benefit programs or perquisites in which you
            now participate. As of the Effective Date, the terms of your
            employment with Tribune will be subject to the provisions of Section
            6.9 of the Merger Agreement, a copy of which section of said
            agreement is attached to this Agreement. However, your employment
            shall remain subject to the terms set forth in the Severance
            Attachment and in the event of any conflict between the terms of
            Section 6.9 of the Merger Agreement and the provisions of the
            Severance Attachment, the provisions of the Severance Attachment
            shall at all times control.

    (b) After the Effective Date, you will be entitled to a bonus incentive
        award under the Executive Incentive Plan at the time and in accordance
        with the terms of the attachment to this Agreement entitled "Certain

        Upon the satisfaction of said conditions precedent, you will receive the
        enhanced severance benefits set forth in the Severance Attachment to
        this Agreement. However, (i) in the event that the merger of Times

        in the manner set forth above within the Severance Protection Period as
        defined in the Severance Attachment, or (ii) your employment is
        terminated under the provisions of paragraph 1 (d), you will not receive

    Agreement entitled "Certain Employee Benefits". You will be entitled to
    receive such certain employee benefits in accordance with their respective
    terms and provisions. However, if this Agreement is terminated under the
    provisions of paragraphs 1 (b) or 1 (d), you will be entitled to receive
    only those Certain Employee Benefits in which you are vested or would
    otherwise be entitled to receive in accordance with the terms and provisions
    of said benefit plans.

6.  Taxes and other Withholding. Except as provided in the Severance Attachment
    with respect to payments to compensate you for any applicable excise taxes,

    federal, state or local taxes. You shall be solely responsible for any and
    all income taxes incurred by you as a result of your receipt of any payment
    contemplated or described in this Agreement. Subject to limitations imposed
    by Times Mirror employee benefit plans, these payments may

    also be reduced by any withholdings, contributions or deductions previously
    authorized by you.

7.  Death. In the event of your death, when amounts or benefits owed to you by
    Times Mirror or Tribune under this Agreement or any attachments to this
    Agreement remain unpaid or unreceived, any such amount or benefit shall be
    paid to your surviving spouse or, if said spouse does not survive you, to
    your estate, in accordance with the provisions of this Agreement and in
    accordance with the terms of any applicable employee benefit plan.

8.  Company Information. You acknowledge that in the course of your employment
    with Times Mirror and/or Tribune, certain information has been disclosed to
    you in confidence that was for the use of Times Mirror and/or Tribune or any
    of their respective subsidiaries or affiliates ("Company Information"). You
    understand and agree that unless such Company Information is placed into the
    public domain by a person other than yourself, you will keep such Company
    Information confidential at all times during and, after your employment by
    Times Mirror and/or Tribune, will not disclose or communicate Company
    Information to any third party and will not make use of Company Information
    on your own behalf or on behalf of any third party. The undertaking set
    forth in this paragraph shall survive the termination of this Agreement.

9.  Restrictive Covenants. In the event that the Enhanced Severance Benefits
    described in paragraph 3 are payable to you, then:

    (a) You agree that for a period of 24 months following the date on which
        your employment with Times Mirror or Tribune is terminated by Times
        Mirror or Tribune, you shall not become employed in a comparable or
        higher level position of any entity or business which is engaged in any
        business activity which constitutes direct competition with Times
        Mirror, Tribune or any significant subsidiary or division of either of
        them, without the prior express written consent of the Chief Executive
        Officer of Times Mirror or Tribune, whichever is applicable.

    (b) You agree that for a period of 12 months after the date on which your
        employment is terminated, you will not directly or indirectly (either on
        your own behalf or on behalf of any other person or entity) attempt to
        persuade or solicit any current or prospective customer of Times Mirror
        or Tribune or any subsidiary or division of either of them with whom you
        had contact during your employment (i) to cease to do business or to
        reduce the amount of business which any customer of Times Mirror or
        Tribune, or any division or subsidiary of either of them, has
        customarily done or contemplates doing with Times Mirror or Tribune, or
        (ii) to do or expand business with a competitor of Times Mirror or

        your employment is terminated, for any reason, you will not, directly or
        indirectly, either on your own behalf or on behalf of any other person
        or entity, solicit any person who is considered to be a management
        employee of Times Mirror or Tribune, or any division or subsidiary
        thereof, to terminate such employment, without the prior express written

                ATTACHMENT TO EMPLOYMENT AND SEVERANCE AGREEMENT
                                 MARK H. WILLES

This attachment to your Employment and Severance Agreement describes the
Enhanced Severance Benefits and terms under which they will be paid if you
remain an employee of The Times Mirror Company until the Effective Date.

a)  Enhanced Severance Payments. If your employment is terminated as of the
    Effective Date or prior to the Effective Date by the company, you will be
    eligible for the following amount of severance:

        three times the sum of your current salary plus your highest bonus
        within the last three years (not including any special bonus payments).
        The amount of your enhanced severance payment equals $9,243,750.

b)  Eligibility for Severance. Enhanced severance payments will be paid in the
    event that you continue in employment through the Effective Date, in the
    event of your death or disability before the Effective Date or in the event
    that the company terminates your employment before the Effective Date.

c)  Severance Protection Period. Severance will be payable in event your
    employment is terminated on account of the change of control during the
    period of time prior to the Effective Date. The Severance Protection Period
    ends on the Effective Date, when your employment will terminate.

d)  Manner of Payment of Severance. Your enhanced severance payments will be
    paid to you in approximately equal annual payments over the three year
    period after the Effective Date, with the first payment to be made within 30
    days after the Effective Date, the second payment in January 2001 and the
    final payment in January 2002.

e)  Executive Perquisites. After your termination of employment at or before the
    Effective Date, the company will continue to reimburse you for one annual
    physical exam per year for the three-year period after the Effective Date.

f)  Other. Upon termination of employment for any reason, you may retain any
    office equipment, including fax machine, cellular phone and personal
    computer currently provided by the company. Upon termination of employment,
    the company will cease to reimburse or provide you with a home security
    system, company car and a personal security guard / driver.

g)  Excess Parachute Payments. To the extent that any payments, including any
    bonus incentive payments, made to you are considered part of an excess
    parachute payment subject to an excise tax, those payments will be fully
    grossed up to compensate you for the amount of the excise tax. The company
    will hire an independent accounting firm to determine the calculations for
    all affected employees and will pay for the services provided by the
    accounting firm. The accounting firm's calculations will be binding unless
    an IRS ruling determines otherwise.

                        CERTAIN COMPENSATION AND BENEFITS
                ATTACHMENT TO EMPLOYMENT AND SEVERANCE AGREEMENT

This attachment to your Employment and Severance Agreement describes how your
bonus incentive award for 2000 will be determined and describes how certain
benefits will be treated as a result of the merger.

a)  2000 Bonus Incentive Award. In the event that you remain employed through
    the Effective Date (whether on active or inactive status as provided in the
    Agreement), your bonus incentive award for 2000 under the Executive
    Incentive Plan will be payable at the maximum level payable under the plan
    (i.e., 225% of your 2000 bonus incentive target which amount shall equal
    $2,250,000). However, no bonus award for 2000 will be payable in the event
    of your voluntary termination of employment before the Effective Date for
    reasons other than those included within the scope of the provisions of the
    Severance Attachment. Your 2000 bonus award will be payable to you on the
    earlier of (i) the date on which your employment is terminated, or (ii) on
    December 31, 2000. In the event that a bonus incentive award is payable
    under subparagraph (i) above, the bonus award for 2000 will not be prorated.
    Any bonus award will be paid or deferred in accordance with your prior
    election regarding your 2000 bonus incentive award. Any amount to be
    deferred will be credited to your account under the Times Mirror Deferred
    Compensation Plan for Executives ("Plan") as of the earlier of (a) the first
    day of the month coinciding with or next following the day your 2000 bonus
    award would be payable as described above or (b) December 31, 2000, but in
    no event earlier than the Effective Date, and will be paid from the Plan in
    accordance with your prior election under said Plan.

b)  Matching Bonus Restricted Stock Program. If you were eligible to and elected
    to participate in the matching bonus restricted stock program for 2000, you
    will receive an additional payment equal to 25% of your 2000 bonus award,
    representing the value of an award under the matching bonus restricted stock
    program, which amount will be aggregated with your 2000 bonus award. This
    additional payment will be paid or deferred in accordance with your prior
    deferral election for your 2000 bonus award under the provisions of the
    Plan, as set forth above. There shall be no requirement for you to place on
    deposit any personally owned shares of Times Mirror stock to receive this
    additional payment.

c)  Stock Options. Prior to the Effective Date, you may exercise any of your
    options to purchase shares of Series A Common Stock of Times Mirror ("Stock
    Options") which are vested. Upon the Effective Date, or upon any earlier
    date which may be considered as a change of control as that term is defined
    under the agreement(s) regarding your Stock Options ("Change of Control
    Date"), and provided you are an employee as of such date, your Stock Options
    will become fully vested.

    In accordance with the provisions set forth in Section 3.4 of the Merger
    Agreement (a copy of which section is attached to this Attachment), Tribune
    will offer you the opportunity to cash out the value of each of your Stock
    Options at $95 per share, reduced


<PAGE>   10

Mark H. Willes


    by the option price of each Stock Option, or to convert each of your Stock
    Options into options to purchase 2.5 shares of Tribune common stock. In
    accordance with the provisions of Section 3.4 of the Merger Agreement, you
    will be required to decide which choice you wish to select for each Stock
    Option and to proceed in accordance with the terms of the offer which will
    be extended to you by Tribune.

d)  Restricted Stock. Upon the Effective Date, or upon any earlier date which
    may be considered as a change of control as that term is defined under the
    provisions of the restricted stock program, and provided you are an employee
    as of such date, to the extent shares of restricted stock are registered in
    your name, all restrictions on such stock will lapse as of such date and
    unrestricted ownership of such shares will vest in you at that time. Any
    personal shares of stock held on deposit by Times Mirror under the Matching
    Bonus Restricted Stock Program will be returned to you at that time.

e)  Executive Perquisites. Any company-paid or reimbursed executive perquisites
    for which you are currently eligible, including financial counseling,
    executive physicals, and club dues and memberships, will be continued during
    your active employment.

                            CERTAIN EMPLOYEE BENEFITS
                ATTACHMENT TO EMPLOYMENT AND SEVERANCE AGREEMENT

This attachment to your Employment and Severance Agreement describes certain
employee benefits which will continue after your termination of employment.

a)  Qualified Retirement Plans. While you are an employee of Times Mirror or any
    of its divisions or subsidiaries (for purposes of this attachment "Times
    Mirror"), you will continue to be eligible to participate in Times Mirror's
    retirement plans in accordance with the respective terms and limitations of
    each plan. Provided you are an employee of Times Mirror as of the Effective
    Date, accrued benefits earned as of the Effective Date under Times Mirror's
    retirement plans will become fully vested. Vesting will apply to any accrued
    benefits under Times Mirror's pension plan(s) and your company matching
    account under the Times Mirror Savings Plus Plan. The retirement plans
    provide for a maximum of one year of benefit accrual service and salary
    credit for severance payments (excluding any non-qualified deferrals),
    subject to statutory limits in the Internal Revenue Code, including but not
    limited to maximum deferrals, benefits or covered compensation. After your
    termination of employment, you will be entitled to receive any vested
    accrued benefits under Times Mirror's retirement plans in accordance with
    the terms of the plans and any elections you make under the plans.
    Distributions under each plan shall be made in accordance with the terms and
    procedures of each respective plan based on your participation under the
    plans.

b)  Supplemental Executive Retirement Plan. You are a participant of the Times
    Mirror Company Executive Retirement Plan for Certain Times Mirror Officers
    (SERP). In accordance with the current provisions of the SERP and changes to
    your SERP benefits approved over the past several years by the Compensation
    Committee, your benefits under the SERP will be based on (i) the Times
    Mirror benefit formula, (ii) your highest 5 year average salary plus your
    highest 5 year average bonus awards earned up to your termination of
    employment, and (iii) your benefit service earned with Times Mirror plus 15
    years of service, which benefit will be reduced by Times Mirror early
    retirement factors for a benefit commencement date before normal retirement,
    $204,332/year (which we have agreed represents your benefit earned under the
    General Mills retirement plans) and any benefits payable from Times Mirror's
    qualified pension plan(s). Under the terms of the SERP and provided you are
    an employee of Times Mirror as the Effective Date, the benefits that you
    have earned under the SERP as of the Effective Date will become fully
    vested. In addition, your benefits under the SERP will be calculated
    including your 2000 bonus incentive award, if any, in the computation of
    your final average compensation under the SERP. Further, you will receive
    credit under the SERP for any severance payments which may be payable as a
    result of the change of control.

c)  Special Retirement Benefit. Provided you remain an employee until the
    Effective Date, in the event of your death or disability before the
    Effective Date, or in the event that your employment is terminated by the
    company for any reason before the Effective Date, you will be eligible to
    receive a special retirement benefit of $970,000/year commencing on April 1,
    2002 payable as a 50% joint and survivor annuity, with your wife as your
    joint


<PAGE>   12

Mark H. Willes


    annuitant. This benefit represents the total pension benefits payable from
    the qualified pension plan and the SERP. If you voluntarily leave Times
    Mirror for any reason before the Effective Date, you shall not be entitled
    to this special retirement benefit; instead you will be entitled to the SERP
    benefit described in subparagraph (b).

d)  Deferred Compensation Plan. Any amounts you have deferred into the Times
    Mirror Deferred Compensation Plan for Executives will be paid to you in
    accordance with your prior elections. In addition, your 2000 bonus incentive
    award payable to you under the terms of the Agreement and its Attachments
    will be deferred in accordance with your deferral election. With respect to
    amounts which are or will be credited to your account in accordance with the
    terms of the Plan, Section 6.9(c) of the Merger Agreement provides that
    Tribune shall credit 9% interest per annum cumulative, from the date any

    amounts which may be deferred under the Plan in connection with the Merger
    or any termination of employment related thereto, whether credited with
    respect to deferrals before or after the Effective Date until all such
    amounts are paid under the Plan in accordance with it terms. If you wish to
    withdraw any funds from the Plan on account of the change of control, the
    Plan provides that you may elect to receive an immediate lump sum payment,
    with a 10% penalty for the unscheduled withdrawal.

    company will reimburse for furnished and functional office space up to 500
    square feet and for the salary and benefits of an executive secretary with a
    compensation package approximately equal to the compensation package of your
    current administrative assistant, adjusted for inflation over the seven-year
    period.

f)  Financial Counseling. If you continue in employment through the Effective
    Date or if your employment is terminated by the company for any reason prior

                                  SECTION 3.4
                      of The Agreement and Plan of Merger
              Between Tribune Company and The Times Mirror Company
                           Dated as of March 13, 2000


     SECTION 3.4.   Options.  (a)  Each of the stock options, if any, to
purchase Company Common Shares (each, a "Company Option") issued by the Company
pursuant to any stock option or similar plan of the Company, and any non-plan
options to acquire Company Common Shares set forth in Section 4.3(a) of the
Company Disclosure Statement issued by the Company pursuant to an option
agreement or otherwise issued by the Company, which are outstanding as of the
Effective Time shall, whether or not then exercisable and vested, become fully
exercisable and vested immediately prior to the Effective Time. Each holder of a
Company Option shall be given the opportunity, prior to the Election Deadline,
to elect either (i) to cause such Company Option (a "Stock Electing Option") to
become and represent an option to purchase Tribune Common Shares (a "Tribune
Option"), in accordance with paragraph (b) of this Section 3.4, or (ii) to cause
such Company Option (a "Cash Electing Option") to be cancelled in exchange for a
single lump sum cash payment (less any applicable income or employment or other
Tax withholding), without interest (the "Company Option Cash Out Amount"), equal
to the product of (A) the number of Company Common Shares subject to such
Company Option immediately prior to the Effective Time and (B) the excess, if
any, of the Per Share Cash Amount over the exercise price per share of such
Company Option, in accordance with paragraph (c) of this Section 3.4. To the
extent any holder of a Company Option shall not have made an election with
respect to such Company Option prior to the Election Deadline, such Company
Option shall be deemed to be a Cash Electing Option.

     (b)  Each Stock Electing Option shall, by virtue of the Merger, and
without any further action on the part of any holder thereof, be assumed by
Tribune and converted into a Tribune Option to purchase that number of Tribune
Common Shares determined by multiplying the number of Company Common Shares
subject to such Company Option immediately prior to the Effective Time by the
Common Exchange Ratio, at an exercise price per Tribune Common Share equal to
the exercise price per share of such Company Option immediately prior to the
Effective Time divided by the Common Exchange Ratio, rounded down to the
nearest whole cent. If the foregoing calculation results in an assumed Company
Option being exercisable for a fraction of a Tribune Common Share, then the
number of Tribune Common Shares subject to such option shall be rounded up to
the nearest whole number of shares. The terms and conditions of each Tribune
Option shall otherwise remain as set forth in the Company Option converted into
such Tribune Option.

     (c)  Each Cash Electing Option shall, by virtue of the Merger, and without
any further action on the part of any holder thereof, be cancelled in exchange
for a single lump sum cash payment (less any applicable income or employment or
other tax withholding), without interest, equal to the Company Option Cash Out
Amount.

     (d)  The adjustment provided herein with respect to any options which are
"incentive stock options" (as defined in Section 422 of the Code), if any,
shall be and is intended to be effected in a manner which is consistent with
Section 424(a) of the Code.

     (e)  All restricted Company Series A Common Shares granted pursuant to any
equity plan or arrangements of the Company, and all individual awards of
restricted Company Series A Common Shares not granted pursuant to any such plan
or arrangement, shall become fully vested immediately prior to the Effective
Time and such Company Series A Common Shares shall be freed of restrictions and
issued to the relevant participant.

                      of The Agreement and Plan of Merger
              Between Tribune Company and The Times Mirror Company
                           Dated as of March 13, 2000


     (p)  Employee Matters. Except as set forth in Section 6.1(p) of the Company
Disclosure Statement, except in connection with any employment offer outstanding
as of the date of this Agreement, the Company shall not, and shall not permit
any of its Subsidiaries to, (i) grant any increases in the compensation of any
of its directors, officers or employees, except for increases required under
employment agreements existing on the date of this Agreement and increases for
officers and employees in the ordinary course of business consistent with past
practice that, in any event, do not increase such officer's or employee's
aggregate cash compensation at target by more than 10% over his aggregate cash
compensation at target in effect on the date of this Agreement, (ii) pay or
agree to pay any pension retirement allowance or other employee benefit not
required or contemplated by any of the existing Company Benefit Plans as in
effect on the date of this Agreement, giving effect to any modification to any
Company Benefit Plan authorized by the Company's Board of Directors prior to the
date of this Agreement and previously delivered in writing to Tribune, to any
such director, officer or employee, whether past or present, or to any other
Person, (iii) pay or award or agree to pay or award any stock option or equity
incentive awards in excess of options to acquire 50,000 shares in the aggregate
or in a manner that is inconsistent with past practice, (iv) enter into any new,
or amend any existing, employment, severance or termination agreement with any
such director, officer or employee which, in the aggregate, would obligate the
Company or its Subsidiaries to pay in excess of $1 million or (v) except as
required to comply with applicable Law, become obligated under any new Company
Benefit Plan which was not in existence on the date of this Agreement, or amend
any such plan or arrangement in existence on the date of this Agreement if such
amendment would have the effect of enhancing any benefits thereunder. The
Company shall, as promptly as practicable, provide Tribune with copies of any
amendments to any Company Benefit Plan (which shall be in accordance with the
foregoing) made after the date of this Agreement and prior to the Effective
Time.

              Between Tribune Company and The Times Mirror Company
                           Dated as of March 13, 2000

     SECTION 6.9. Employee Benefits.

     (a)  Obligations of Tribune; Continuance of Benefits. For a period of one
year immediately following the Effective Time, the coverage and benefits
provided to employees and former employees of the Company and its Subsidiaries
("Company Employees") pursuant to employee benefits plans or arrangements
maintained by Tribune or any of its Subsidiaries shall be no less favorable, in
the aggregate, than those provided to such employees immediately prior to the
Effective Time. Except as provided in Section 3.4 and 6.9(c), notwithstanding
the foregoing, nothing herein shall require (i) the continuation of any
particular benefit plan or prevent the amendment or termination thereof (subject
to the maintenance, in the aggregate, of the benefits, or (ii) Tribune to
continue or maintain any stock option, stock purchase or other incentive plan
related to the equity of the Company.

     (b)  Pre-Existing Limitations; Deductible; Service Credit. With respect to
any incentive, benefits and perquisite plans and programs ("Benefit Plans") of
Tribune or any Subsidiary of Tribune in which the Company Employees participate
effective as of the Effective Time or thereafter, Tribune shall: (i) waive any
limitations as to pre-existing conditions, exclusions and waiting periods with
respect to participation and coverage requirements applicable to the Company
Employees under any Benefit Plan that is an employee welfare benefit within the
meaning of Section 3(1) of ERISA ("Welfare Plan") in which such Company
Employees may be eligible to participate after the Effective Time (provided,
however, that no such waiver shall apply to a pre-existing condition, exclusion
or waiting period applicable to any Company Employee to the extent that he or
she was, as of the Effective Time, excluded from participation in a Company
Benefit Plan by reason of such pre-existing condition, exclusion or waiting
period, and provided, further, that no such waiver shall apply to a pre-existing
condition, exclusion or waiting period of any Company Employee unless the
Company Employee enrolls in the applicable Welfare Plan when first eligible to
do so), (ii) in the event Company Employees are transferred to a new Welfare
Plan within the plan year beginning January 1, 2000, for purposes of
accumulating annual deductibles, co-payments and out-of-pocket requirements,
provide each Company Employee with credit for any co-payments and deductibles
paid prior to the Effective Time, but within such plan year, for purposes of
satisfying any applicable deductible or out-of-pocket requirements under any
Welfare Plan in which such employees may be eligible to participate after the
Effective Time, and (iii) recognize all service of the Company Employees with
the Company, for all purposes other than benefit accrual, in any Benefit Plan in
which such Company Employees may be eligible to participate after the Effective
Time. Prior to the Effective Time, the Board of Directors of Tribune, or an
appropriate committee of non-employee directors thereof, shall adopt a
resolution consistent with the interpretive guidance of the SEC so that the
acquisition by any officer or director of the Company who may become a covered
person of Tribune for purposes of Section 16 of the Exchange Act and the rules
and regulations thereunder ("Section 16") of Tribune Common Shares or options to
acquire Tribune Common Shares pursuant to this Agreement and the Merger shall be
an exempt transaction for purposes of Section 16.

                              SECTION 6.9 (CONT.)
                      of The Agreement and Plan of Merger
              Between Tribune Company and The Times Mirror Company
                           Dated as of March 13, 2000

     (c)  Employment and Severance Arrangements. As of the Effective Time,
Tribune shall assume, honor and perform in accordance with their terms all
employment, severance, change in control and other such agreements of the
Company and its Subsidiaries and Affiliates, giving effect to any amendment or
modification to any such agreement authorized by the Company's Board of
Directors prior to the date of this Agreement (the "Employment Arrangements").
With respect to the Times Mirror Deferred Compensation Plan For Executives and
the Deferred Plan for Directors Fees, Tribune shall credit 9% interest per
annum, cumulative, from the date any amount is credited to a participant under
any such plans effective with respect to all amounts credited under such plans
as of the Effective Time, and on all amounts which may be deferred under such
plans in connection with the Merger or any termination of any employment
related thereto, whether credited with respect to deferrals before or after the
Effective Time until all such amounts are paid under the plan in accordance
with its terms. Tribune shall pay the reasonable attorney's fees of the
individual party to the applicable Employment Arrangement in the event such
individual party files a claim in good faith to enforce Tribune's obligations
and prevails in such action. Such individual parties are hereby specifically
made a third party beneficiary of this Section 6.9(c).

     (d)  Successor Obligations. Notwithstanding any other provision of this
Agreement, in the event Tribune sells or otherwise disposes of any Subsidiary
of the Company coincident with or within one year after the Effective Time,
Tribune shall require as a condition of such sale or disposition that the buyer
shall assume all obligations of Tribune under this Section 6.9. In the
alternative, Tribune may elect to guarantee the payment of such obligations.
