                                     between

                               Kenneth W. Freeman
                                        &
                   Corning Clinical Laboratories, Incorporated

    This EMPLOYMENT AGREEMENT (the "Agreement") is entered into between CORNING
CLINICAL LABORATORIES, INC. (the "Company"), a Delaware corporation having its
principal place of business at One Malcolm Avenue, Teterboro, NJ 07608, and
KENNETH W. FREEMAN (the "Executive").

    WHEREAS, Executive has been employed by the Company as President and Chief
Executive Officer; and WHEREAS, the Company considers the services of the
Executive to be unique and essential to the success of the Company's business;
and

    WHEREAS, it is anticipated that the Company will be subject to a tax-free
spin-off by Corning Incorporated ("Corning") (the "Spin-off") and the parties
desire that the Executive continue as President and Chief Executive Officer of
the Company following the Spin-off; and

    WHEREAS, the Company and the Executive now wish to enter into an agreement
of employment that will constitute the sole and exclusive agreement relating to
the employment of Executive by the Company on the terms and conditions set forth
herein.



    NOW, THEREFORE, in consideration of the foregoing premises, the mutual
covenants, terms and conditions set forth herein, and other valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, it
is hereby agreed between the Corporation and the Executive as follows:

1.       Employment: The Company shall continue to employ the Executive in a
         full-time capacity in the position set forth in this paragraph, and the
         Executive shall continue to accept such employment upon the terms and
         conditions set forth herein. Such employment shall be in the capacity
         of President and Chief Executive Officer of the Company, and as a
         Director and Chairman of the Board of Directors of the Company,
         reporting directly to the Board. The Company shall nominate the
         Executive as a Director of the Company and shall use its best efforts
         to have the Executive elected and re-elected to the Board for the
         duration of the "Employment Term" (as hereinafter defined).

2.       Term: Unless earlier terminated pursuant to Section (9) hereof, the
         term of employment under this agreement shall commence on the later of
         January 1, 1997 or the date upon which the Spin-off is consummated (the
         "Effective Date"), and shall continue through December 31, 1999 (the
         "Employment Term"). On or before June 1, 1999, the Company and the
         Executive agree to use their good faith efforts to negotiate a renewal
         of this Agreement (the "Renewal Agreement"), on mutually satisfactory
         terms and conditions. In the event that the Company and Executive are
         unable to agree to a Renewal Agreement, and subject to continued
         service by the Executive through December 31, 1999 (absent any
         termination by the Company without Cause, or termination by the
         Executive for Good Reason, or as a result of the death or disability

                                       2


         of the Executive, in each case giving rise to payments pursuant to
         Section 12 hereof) (each individually a "Section 12 Event"), then upon
         the expiration of this Agreement on December 31, 1999, and in lieu of
         any other amounts otherwise payable to the Executive pursuant to
         Section 12 hereof, the Executive shall receive the "Non-Renewal
         Payment" (as hereinafter defined). "Non-Renewal Payment" shall mean (i)
         a lump-sum cash payment equal to two times the highest annual cash
         compensation paid to the Executive during the Employment Term, and (ii)
         reimbursed health benefits under COBRA for eighteen months for the
         Executive and his family following the expiration of this Agreement.
         Notwithstanding the foregoing, the Executive shall not be entitled to
         receive the Non-Renewal Payment if upon the expiration of the
         Employment Term (and absent any Section 12 Event) the Executive accepts
         an executive position at Corning on terms and conditions satisfactory
         to the Executive.

3.       Duties: During the Employment Term, the Executive shall, subject to the
         supervising powers of the Board, have those powers and duties
         consistent with his position as Chief Executive Officer and Chairman,
         which powers shall in all cases include, without limitation, the power
         of supervision and control over, and responsibility for, the general
         management and operations of the Company. Executive agrees to devote
         substantially all his working time and attention to the business of the
         Company. The Executive shall not, without the prior written consent of
         the Company's Board of Directors, be directly or indirectly engaged in
         any other trade, business or occupation for compensation requiring his
         personal services during the Employment Term. Nothing in this agreement
         shall preclude the Executive from: (i) engaging in charitable and
         community activities or 

                                        3


         from managing his personal investments, or (ii) serving as a member of
         the board of directors of an unaffiliated company not in competition
         with the Company, subject however, in each such case of board
         membership, to approval by the Company's Board of Directors (not to be
         unreasonably withheld).

4.       Place of Performance: The principal place of employment of the
         Executive shall be at the Company's principal executive offices in
         Teterboro, New Jersey, or such other location as may be agreed to by
         the Board and Executive.

5.       Cash Compensation: Executive shall be compensated for services rendered
         during the Employment Term as follows:

         (a) Base Salary: Executive shall be compensated at an annual base
         salary of no less than $500,000 (the base salary, at the rate in effect
         from time to time, is hereinafter referred to as the "Base Salary").
         The Company's Board of Directors shall review and may, if appropriate,
         at its discretion, increase this annual base salary effective the first
         day of any future new year during the Employment Term; provided that
         the Base Salary shall be increased annually to reflect ordinary salary
         actions generally granted to other Company executives. The Base Salary
         shall be payable in equal semi-monthly installments.

         (b) Variable (bonus) Pay: In addition to the Base Salary provided for
         in Section 5(a) above, the Company will provide annual bonus awards to
         Executive under its Variable Compensation (VC) program in accordance
         with the plan and financial performance targets as established by the
         Company's shareholders and/or Board of Directors. During the Employment
         Term, Executive's target incentive opportunity under the Company's VC

                                        4


         program will be no less than 65% of Base Salary as in effect at the
         time such target incentive opportunity is established.

6.       Equity/Awards: Executive may be awarded additional compensation (such
         as stock options or restricted stock) (collectively the "Annual 
         Incentive Awards") pursuant to the present or any future incentive 
         compensation or long-term compensation program established for 
         the senior officers of the Company (collectively the "Incentive
         Compensation Programs"), which, in the sole judgment of the Company's
         Board of Directors, is appropriate for the position occupied by
         Executive and his performance therein; provided that no executive,
         consultant or individual shall receive any annual award under the
         Incentive Compensation Programs in excess of the annual award (if any)
         made to the Executive, without Executive's express written consent.
         Compensation granted under such plans will be subject to the actual
         provisions and conditions applicable to such plans.

7.       Initial Incentive Awards:

         (a) The Executive is hereby granted (i) options on 180,000 shares of
         common stock of the Company ("Common Stock") at an exercise price equal
         to the lesser of $12.50 or the fair market value of the Common Stock as
         of the effective date of the Spin-Off (the "Exercise Price"); and (ii)
         90,000 shares of the Company's common stock (collectively the "Initial
         Incentive Awards"). The Initial Incentive Awards shall be subject to
         the general terms and conditions of the incentive plans under which
         they were granted subject in each case to any provisions of this
         Agreement providing for accelerated vesting.

                                       5

         (b) The Executive's rights with respect to certain previously granted
         incentive awards in Corning shall be converted into (i) options on
         185,600 shares of Common Stock (representing first and second year
         CPP-6 stock options under Corning's long-term plan), and (ii) 55,085
         shares of Common Stock (the "CCL Career Shares") (such CCL Career
         Shares to be subject to the vesting provisions set forth in Annex A
         hereto, absent accelerated vesting under the terms of this Agreement)
         (collectively "Converted Incentive Awards").

         (c) The final number of Initial Incentive Awards and Converted
         Incentive Awards granted to the Executive shall be adjusted pro rata
         upward or downward, as the case may be, depending on the appropriate
         pricing formula finally adopted with the approval of the Executive, and
         the extent to which the price of the Common Stock on the effective date
         of the Spin-off is less than or greater than $12.50 per share.

8.       Employee Benefits:

         (a) General Provisions: Except as expressly provided in this Agreement,
         Executive shall be eligible to participate in all employee benefit and
         welfare plans offered by the Company (e.g. Life Insurance, Medical &
         Dental Insurance, Travel, Accident, STD&LTD, Flexible Spending
         Accounts, Regular and Supplemental AD&D, Optional/Supplemental Life
         Insurance, Investment Plan - 401k, Employee Stock Purchase Plan and
         other personal benefit plans of the Company) on a basis which is no
         less favorable to the Executive than that made available to other
         senior officers of the Company.

                                       6


         (b) Transferred Executive Supplemental Retirement Plan: (i) Executive
         will be eligible to participate in the "Transferred Executive
         Supplemental Retirement Plan" (the "SRP") established by the Company
         for certain executives of the Company, effective upon the Effective
         Date. Under the terms of such plan, Executive will be entitled to
         receive a nonqualified retirement benefit in accordance with the terms
         and provisions of the plan, as administered by the Company's Board of
         Directors, subject to the terms of this Agreement.

               (ii) Notwithstanding any terms of the SRP to the contrary,
          Executive shall be entitled to receive a retirement pension benefit
          under this Agreement (the "Company Non-Qualified Benefit") as provided
          for below. The Company Non-Qualified Benefit shall be an annuity
          commencing on the later of (i) his date of termination or (ii) the
          Executive's 57th birthday (the "SRP Commencement Date"), and shall be
          (1) fully equivalent in value to the pension benefits Executive would
          have received under the Corning non-qualified and qualified pension
          plans as in effect on the date of this Agreement (including all
          across-the-board plan improvements or benefit decreases and/or
          successor plans, in each case adopted after the date of this Agreement
          and applicable to the class of executives of which the Executive was a
          part while employed by Corning), (2) based on Executive's combined
          years of service with the Company and Corning (but in any case not
          less than 34 years of service), (3) computed on an unreduced basis as
          if Executive were a retiree, rather than on a deferred vested basis,
          and (4) based on all compensation earned by Executive from Corning and
          Company through to the SRP Commencement Date (provided that for
          purposes of such computation, Executive's

                                       7


         benefit eligible compensation shall be his 1997 Base Salary and Bonus
         and such amount increased at 5% per annum for subsequent years);
         provided that if the Executive terminates his employment under this
         Agreement without Good Reason or the Company terminates the Executive's
         employment under this Agreement with Cause, then the pension benefits
         payable to the Executive under the SRP shall be determined based only
         on actual years of service and compensation through to the Termination
         Date.

               (iii) On or before the Effective Date, the Company shall deliver
          to Executive a standby letter of credit in the amount of $5.4 million,
          in form acceptable to Executive and his counsel and with an evergreen
          term of no less than eighteen (18) months, to ensure that the
          Company's obligation under the SRP and the Company Non-Qualified
          Benefit are fully funded and secured on an after-tax basis to the
          Executive (the "SRP LC"). As of the first day of any calendar year
          thereafter (the "Adjustment Date") as of which the Company's pension
          liability (on an after-tax basis) to Executive as computed hereunder,
          as determined by an actuary acceptable to Executive on or before
          November 1 of the preceding calendar year, has a present value that
          exceeds by more than $250,000 the SRP LC (on an after-tax basis), the
          Company shall, within 60 days of the Adjustment Date, increase the
          amount of the SRP LC or secure and deliver to the Executive an
          additional letter of credit in form acceptable to the Executive and
          his counsel so that, in the aggregate, the letter(s) of credit then in
          place are not less than the present value of such liability (on an
          after-tax basis).

               (iv) Immediately upon (x) the termination of Executive's
          employment with the Company for any reason, including, without
          limitation, failure to negotiate a Renewal 

                                       8


         Agreement (and other than a termination of Executive's employment by
         the Company for Cause or by the Executive without Good Reason), (y)
         failure of the Company to renew the SRP LC or increase the amount of
         the SRP LC or secure an additional letter of credit, as provided herein
         (in each case, without the consent of the Executive not to do so), or
         (z) upon the Executive's retirement, the Executive may draw on the SRP
         LC; it being understood that the Executive may elect to draw on the SRP
         LC (and any supplemental letter of credit) pursuant to subclause (y)
         above and continue his employment hereunder.

               (v) Amounts payable to the Executive in satisfaction of the
          Company Non-Qualified Benefit shall be reduced by (i) any qualified
          plan benefits actually received by Executive under Corning's qualified
          plan ("Qualified Corning Benefits") and (ii) any non-qualified
          benefits to the extent funded pursuant to Section III (c) of the
          Transition Agreement, dated as of December 18, 1996 between Corning
          and the Executive, and actually received by the Executive ("Section
          III (c) Benefits"), and any amounts realized by the Executive upon
          drawing upon the SRP LC (or any supplemental letter of credit) shall
          be adjusted to take into account such Qualified Corning Benefits and
          Section III (c) Benefits.

         (c) Relocation: The Company shall reimburse the Executive up to $10,000
         per month (grossed-up for tax purposes at a rate of 45%) until the
         earlier of: (i) suitable housing in the New York Metropolitan area
         being obtained by the Executive, or (ii) June 30, 1998. lf the
         Executive has not utilized Corning's relocation benefits prior to the
         Effective Date, the Company shall extend equal benefits (to the extent
         the Company's

                                       9

         relocation policies are of lesser value to the Executive) for
         relocating the Executive and his family from the Corning, New York area
         to the New York City Metropolitan area. In addition, the Company will
         provide for an interest-free housing loan to the Executive in the
         amount of $400,000, all of which shall be forgiven in five (5) annual
         installments at each annual anniversary of this Agreement's Effective
         Date. Any compensation income to Executive resulting from the loan
         forgiveness or interest-free features of this loan will be grossed-up
         for tax purposes at the Executive's effective tax rate.


         (d) Vacation and Sick Leave: Executive shall be entitled to vacation
         and sick leave in accordance with the vacation and sick leave policies
         adopted by the Company from time to time, provided that the Executive
         shall be entitled to no less than five (5) weeks of paid vacation each
         calendar year. Any vacation shall be at such times and for such periods
         as shall be mutually agreed upon between the Executive and the Company.
         The Executive shall be entitled to all public holidays observed by the
         Company.

9.       Applicable Taxes: There shall be deducted from any compensation
         payments made under this Agreement any federal, state and local taxes
         or other amounts required to be withheld by any entity having
         jurisdiction over the matter.

10.      Miscellaneous Benefits: During the Employment Term, the Company shall
         provide the Executive with the following additional benefits: 

         (a) Business Travel and Expenses: Executive shall be reimbursed by the
         Company for reasonable travel and other business expenses, as approved
         by the Company, which are

                                       10

         incurred and accounted for in accordance with the Company's normal
         practices and procedures for reimbursement of expenses.

         (b) Legal Fees: The Company shall reimburse Executive for reasonable
         legal fees and disbursements incurred in connection with the
         negotiation, preparation and implementation of this Agreement (grossed
         up for tax purposes at a rate of 45%).

         (c) Clubs and Memberships: The Company will reimburse Executive for
         annual and one-time costs associated with memberships for the Executive
         and his family in a country club and city club (grossed-up for tax
         purposes at a rate of 45%).

         (d) Executive Driver: In order to ensure the accessibility and safety
         of the Executive during the Employment Term, the Company will reimburse
         Executive for the costs of an executive driver comparable to the costs
         presently incurred on behalf of the Executive, subject to annual COLA
         adjustments (grossed up for tax purposes at a rate of 45%).

         (e) Use of Aircraft: In order to ensure the accessibility and safety of
         the Executive during the Employment Term, the Company shall reimburse
         Executive for all costs associated with the Executive's use of aircraft
         in accordance with the Company's policies, whether for business
         purposes or for personal reasons, whether the aircraft is being
         chartered or is Company-owned. Any payments under this provision which
         are to be treated as taxable compensation to the Executive (in
         accordance with IRS rules and regulations) will be grossed-up for tax
         purposes at a rate of 45%.

         (f) Automobile Expenses: The Company will provide Executive with a
         gross automobile allowance of $1,070 per month (or other greater
         monthly amount as is

                                       11

         provided to other senior executives of the Company) in accordance with
         the provisions of the Company's auto allowance program.

         (g) Financial Counseling and Legal Services: The Company shall
         reimburse the Executive for financial counseling, tax preparation and
         legal services (grossed-up for tax purposes at a rate of 45%) in an
         annual amount comparable to that paid on behalf of similarly situated
         senior executives, but in no event less than $25,000/year.

         (h) Non-Exclusivity: Nothing in this Agreement shall prevent the
         Executive from being entitled to receive any additional compensation or
         benefits as approved by the Company's Board of Directors.

11.      Termination of Employment: Notwithstanding any other provisions of this
         Agreement to the contrary, the employment of the Executive pursuant to
         this Agreement may be terminated as follows:

         (a) Termination by the Company For Cause: Executive may be terminated
         for "Cause" by the Company as provided below. As used herein, the term
         "Cause" shall mean (i) conviction of the Executive of a felony; (ii) if
         Executive is not disabled (as defined below), a willful failure or
         refusal to substantially perform the duties and services specified
         herein for a period of not less than thirty (30) days, and after having
         been afforded (x) written notice of any alleged failure to
         substantially perform such duties and services and (y) a reasonable
         opportunity to cure any alleged failure; (iii) the commission by the
         Executive of fraud or theft against, or embezzlement from, the Company;
         or (iv) gross misconduct intentionally undertaken by the Executive that
         is demonstrably and materially injurious to the operations of the
         Company. For purposes of this section, no

                                       12

         act or failure to act on Executive's part shall be considered to be
         reason for termination for Cause if done, or omitted to be done, by
         Executive in good faith and with the reasonable belief that the action
         or omission was in the best interests of the Company. Cause shall not
         exist unless and until there shall have been delivered to the Executive
         a copy of a resolution, duly adopted by the affirmative vote of not
         less than two thirds of the entire membership of the Board at a meeting
         of the Board held for the purpose (after ten (10) days' prior written
         notice to the Executive of such meeting and the purpose thereof and an
         opportunity for him, together with his counsel, to be heard before the
         Board at such meeting), of finding that in the good faith opinion of
         the Board, the Executive was guilty of the conduct set forth above in
         this Section 11(a) and specifying the particulars thereof in detail. As
         set forth more fully in Section 11(f) hereof, the "Date of Termination"
         shall be the date specified in the "Notice of Termination;" provided,
         however, that in the case of a termination for Cause under clause (ii)
         above, the Date of Termination shall not be earlier than 30 days after
         delivery of the Notice of Termination. Anything herein to the contrary
         notwithstanding, if, following a termination of the Executive's
         employment by the Company for Cause based upon the conviction of the
         Executive for a felony, such conviction is overturned in a final
         determination on appeal, the Executive shall be entitled to the
         payments and the economic equivalent of the benefits the Executive
         would have received if his employment had been terminated by the
         Company without Cause.

         (b) Termination By the Company For Disability: At the sole discretion
         of the Company's Board of Directors, Executive may be terminated if the
         Executive is disabled (as defined below) and shall have been absent
         from his duties with the Company on a full-time basis for

                                       13


         one hundred and twenty (120) consecutive days, and if within thirty
         (30) days after written Notice of Termination is given by the Company
         to the Executive, the Executive shall not have resumed the performance
         of his duties hereunder on a full-time basis. In this event, the date
         of termination shall be thirty (30) days after Notice of Termination is
         given by the Company (provided that the Executive shall not have
         returned to the full-time performance of his duties). As used herein,
         the term "disabled" shall mean that the Executive is unable, as a
         result of a medically determinable physical or mental impairment, to
         perform the duties and services of his position.

         (c) Death: The Executive's employment shall terminate upon his death,
         and the date of his death shall be the Date of Termination for purposes
         of this Agreement.

         (d) Termination by the Executive for Good Reason: The Executive may
         terminate his employment hereunder for "Good Reason," provided that the
         Executive shall have delivered a Notice of Termination within ninety
         (90) days after the occurrence of the event of Good Reason giving rise
         to such termination. For purposes of this Agreement, "Good Reason"
         shall mean the occurrence of one or more of the following
         circumstances, without the Executive's express written consent, which
         are not remedied by the Company with thirty (30) days of receipt of the
         Executive's Notice of Termination:

                       (i) an assignment to the Executive of any duties
                   materially inconsistent with his positions, duties,
                   responsibilities and status with the Company, or any material
                   limitation of the powers of the Executive not consistent with
                   the powers of the Executive contemplated by Section (3)
                   hereof;

                                       14


                       (ii) any removal of the Executive from, or any failure to
                   re-elect the Executive to, the positions specified in Section
                   (1) of this Agreement;

                       (iii) the change of the Executive's title as specified by
                   Section (1) of this Agreement;

                       (iv) the Company's requiring the Executive without his
                   written consent to be based at any office or location more
                   than 75 miles commuting distance from the location as
                   described in Section (4) of this Agreement;

                       (v) a reduction in the Executive's Base Salary or
                   Variable Compensation bonus opportunity as in effect from
                   time to time, without his written consent;

                       (vi) the failure of the Company to continue in effect any
                   Benefit Plan that was in effect on the date hereof or provide
                   the Executive with equivalent benefits, without his written
                   consent;

                       (vii) the failure of the Company, within not more than
                   thirty (30) days after the Effective Date, to have the
                   Executive duly elected as a member of its Board of Directors
                   and to maintain the Executive in such position at all times
                   thereafter, for so long as he shall serve as Chief Executive
                   Officer of the Company;

                       (viii) any other material breach by the Company of this
                   Agreement;

                       (ix) a Change in Control;

                       (x) a failure of the Company to secure a written
                   assumption by any successor company as provided for in
                   Section 15(g) hereof; or

                                       15


                       (xi) the failure of the Company to secure, maintain,
                   renew or supplement the SRP LC (and any supplemental letter
                   of credit) as provided for in Section 8(b)(iii) hereof. In
                   the event of a termination for Good Reason, the Date of
                   Termination shall be the date specified in the Notice of
                   Termination, and shall be more than thirty (30) days after
                   the Notice of Termination.

         In the event of a termination for Good Reason pursuant to Section
         11(d)(xi) hereof, the Executive shall retain the right to draw on the
         SRP LC (and any supplemental letter of credit) as provided for in
         Section 8(b) hereof.

         (e) Other Terminations: Notwithstanding the foregoing, the Executive
         may terminate his employment at any time, subject to the provisions of
         Section (11)(f) hereof. If the Executive's employment is terminated
         hereunder for any reason other than as set forth in Sections
         (11)(a)-(11)(d) hereof, the date on which a Notice of Termination is
         given or any later date (within 30 days) set forth in such Notice of
         Termination shall be the Date of Termination.

         (f) Notice of Termination: Any termination of the Executive's
         employment hereunder by the Company or by the Executive shall be
         communicated by written Notice of Termination to the other party
         hereto. For purposes of this Agreement, a "Notice of Termination" shall
         mean a notice which shall indicate the specific termination provision
         in this Agreement relied upon and shall set forth in reasonable detail
         the facts and circumstances claimed to provide a basis for termination
         of the Executive's employment under the provisions so indicated.


                                       16


12.      Compensation upon Termination or during Disability:

         (a) Disability Period. During any period during the Employment Term
         that the Executive fails to perform his duties hereunder as a result of
         incapacity due to physical or mental illness ("Disability Period"), the
         Executive shall continue to (i) receive his full Base Salary and bonus
         otherwise payable for that period of the Employment Term including the
         Disability Period and (ii) participate in the Benefit Plans. Such
         payments made to the Executive during the Disability Period shall be
         reduced by the sum of the amounts, if any, payable to the Executive at
         or prior to the time of any such payment under disability benefit plans
         of the Company or under the Social Security disability insurance
         program, where such amounts were not previously applied to reduce any
         such payment.

         (b) Death. If the Executive's employment hereunder is terminated as a
         result of his death, then: (i) the Company shall pay the Executive's
         estate or designated beneficiary, as soon as practicable after the Date
         of Termination, a lump sum payment equal to (1) any Base Salary
         installments due in the month of death and any reimbursable expenses
         accrued or owing the Executive hereunder as of the Date of Termination,
         (2) a pro rata portion of any bonus owed to the Executive for that
         portion of the Employment Term through to the Date of Termination, and
         (3) the greater of (x) Base Salary payments otherwise payable for the
         remainder of the Employment Term or (y) two (2) times the average
         annual Base Salary paid to the Executive prior to his death (the
         payments provided for in subclauses (x) and (y) are the "Reduced
         Severance Benefits"), and (ii) the Initial Incentive Awards, Converted
         Incentive Awards, and all other Annual Incentive Awards granted to the
         Executive shall


                                       17

         immediately become fully vested as of the Date of Termination, subject
         to such exercise periods as shall be provided for under the terms of
         the initial grant.

         (c) Disability. If the Executive's employment hereunder is terminated
         as a result of Disability, then (i) the Company shall pay the
         Executive, as soon as practicable after the Date of Termination (1) any
         Base Salary and any reimbursable expenses accrued or owing the
         Executive hereunder as of the Date of Termination, (2) a pro rata
         portion of any bonus owed to the Executive for that portion of the
         Employment Term through to the Date of Termination, and (3) the
         "Reduced Severance Benefits;" and (ii) the Initial Incentive Awards,
         Converted Incentive Awards, and all other Annual Incentive Awards
         granted to the Executive shall immediately become fully vested as of
         the Date of Termination, subject to such exercise periods as shall be
         provided for under the terms of the initial grant.

         (d) Termination for Cause or by the Executive other than for Good
         Reason. If the Executive's employment hereunder is terminated by the
         Company for Cause or by the Executive (other than for Good Reason),
         then (i) the Company shall pay the Executive, as soon as practicable
         after the Date of Termination, any Base Salary and any reimbursable
         expenses accrued or owing the Executive hereunder for services as of
         the Date of Termination; and (ii) the Executive shall immediately
         forfeit any unvested CCL Career Shares. In the event of termination by
         the Company for Cause, the Executive shall have the right to exercise
         the vested unexercised portion of any Initial Incentive Awards,
         Converted Incentive Awards or any other Annual Incentive Awards prior
         to the Date of Termination, and the unexercised portion of any such
         awards shall be forfeited thereafter. In the event of termination by
         the Executive other than for Good Reason, the Executive shall have the


                                       18


         right to exercise the vested unexercised portion of any Initial
         Incentive Awards, Converted Incentive Awards or any other Annual
         Incentive Awards then held by the Executive for such period following
         the Date of Termination as shall be provided for under the terms of the
         initial grant, and the unexercised portion of any such awards shall be
         forfeited thereafter.

         (e) Termination by Company Without Cause or by Executive with Good
         Reason:

             Executive's employment may be terminated without Cause by the
          Company's Board of Directors (other than as a result of Disability) or
          by the Executive for Good Reason, provided that in such event:

                       (i) Executive shall be entitled to receive three (3)
                   years base salary (at the Executive's effective annual rate
                   on the date of termination) to be paid in a lump-sum (net of
                   appropriate withholdings) within sixty (60) days of the Date
                   of Termination;

                       (ii) Executive shall be entitled to receive three (3)
                   years of his annual bonus award (defined to be three (3)
                   times his most recent target incentive opportunity under the
                   Variable Compensation plan times his annual base salary on
                   the date of termination) to be paid in a lump sum (net of
                   appropriate withholdings) within sixty (60) days of the Date
                   of Termination;

                       (iii) Executive shall be entitled to continue
                   participation in the Company's health and benefit plans (to
                   the extent allowable in accordance with the administrative
                   provisions of those plans and applicable federal and state
                   law) for a period of up to three (3) years or until Executive
                   is covered by a successor employer's benefit plans, whichever
                   is sooner;

                                       19


                       (iv) The Initial Incentive Awards, Converted Incentive
                   Awards and any other Annual Incentive Awards granted to the
                   Executive shall become vested and fully exercisable as of the
                   Date of Termination; and

                       (v) In the event that the Executive receives any payment
                   or benefit (including but not limited to the payments or
                   benefits pursuant to Section 12 of this Agreement (a
                   "Payment") that is subject to the excise tax (the "Excise
                   Tax") under Section 4999 of the Internal Revenue Code of
                   1986, as amended (the "Code"), the Company shall pay to the
                   Executive, as soon thereafter as practicable, an additional
                   amount (a "Gross-Up Payment") such that the net amount
                   retained by the Executive, after deduction of any Excise Tax
                   imposed upon the Payment and any federal, state and local
                   income tax and Excise Tax imposed upon the Gross-Up Payment,
                   shall be equal to the Payment. The determination of whether
                   an Excise Tax is due in respect to any payment or benefit,
                   the amount of the Excise Tax and the amount of the Gross-Up
                   Payment shall be made by an independent auditor (the
                   "Auditor") jointly selected by the Company and the Executive
                   and paid by the Company. If the Executive and the Company
                   cannot agree on the firm to serve as the Auditor, then the
                   Executive and the Company shall each select one nationally
                   recognized accounting firm and those two firms shall jointly
                   select the nationally recognized accounting firm to serve as
                   the Auditor. Notwithstanding the Payment, (i) any other
                   payments or benefits received or to be received by the
                   Executive in connection with a Change in Control or the
                   Executive's termination of employment (whether pursuant to
                   the terms of this Agreement or any other plan, arrangement or
                   agreement

                                       20


         with the Company, any person whose actions result in a Change in
         Control or any person affiliated with the Company or such person) shall
         be treated as "parachute payments" within the meaning of Section
         280G(b)(2) of the Code, and all "excess parachute payments" within the
         meaning of Section 280G of the Code shall be treated as subject to the
         Excise Tax, unless in the opinion of the tax counsel selected by the
         Auditor, such other payments or benefits (in whole or in part) do not
         constitute parachute payments, or are otherwise not subject to the
         Excise Tax, and (ii) the Executive shall be deemed to pay federal
         income tax at the highest marginal rate applicable in the calendar year
         in which the Gross-up Payment is made, and state and local income taxes
         at the highest marginal rate of taxation in the state and locality of
         the Executive's residence on the Date of Termination, net of the
         maximum reduction in federal income taxes which could be obtained from
         deduction of such state and local taxes. In the event the actual Excise
         Tax or such income tax is more or less than the amount used to
         calculate the Gross-Up Payment, the Executive or the Company, as the
         case may be, shall pay to the other an amount reflecting the actual
         Excise Tax or such income tax.

(f)      Change in Control. For purposes of this Agreement, a
         "Change-in-Control" is defined to be:

                  (i) any person (as such term is used in Sections 13(d) and
                  14(d)(2) of the Securities Exchange Act of 1934) becoming the
                  beneficial owner, directly or indirectly, of Company
                  securities representing 20% or more of the combined voting
                  power of the Company's then outstanding securities; or

                                       21


                  (ii) the majority of the Board consists of individuals other
                  than Incumbent Directors, which term means the members of the
                  Board as of the date of the Spin-off and any other Director
                  elected to the Board with the consent of the Executive,
                  provided that any person becoming a director subsequent to
                  such date whose election or nomination for election was
                  supported by two-thirds of the directors who then comprised
                  the Incumbent Directors shall be considered to be an Incumbent
                  Director; or 

                  (iii) the Company's shareholders approve a merger (pursuant to
                  which the Company is not the surviving entity), consolidation,
                  sale or disposition of all or substantially all of the
                  Company's assets or a plan of partial or complete liquidation;
                  provided that notwithstanding anything to the contrary in this
                  subclause (iii), no such merger, consolidation or sale shall
                  be deemed to constitute a "Change in Control" if such
                  transaction or series of transactions required the Executive
                  to be identified in any United States securities law filing as
                  a person or a member of any group acquiring, holding or
                  disposing of beneficial ownership of the Company's securities
                  and/or assets and effecting a "Change in Control" as defined
                  in this subclause (iii).

13.      Arbitration: In the event of any difference of opinion or dispute
         between the Executive and the Company with respect to the construction
         or interpretation of this Agreement or the alleged breach thereof,
         which cannot be settled amicably by agreement of the parties, then such
         dispute shall be submitted to and determined by arbitration by a single
         arbiter in the city of New York, New York in accordance with the rules
         then in effect of the Commercial

                                       22

         Arbitration Panel of the AMERICAN ARBITRATION ASSOCIATION, and judgment
         upon the award rendered shall be final, binding and conclusive upon the
         parties and may be entered in the highest court, state or federal,
         having jurisdiction. The costs of the arbitration shall be borne as
         determined by the arbitrator; provided, however, that if the Company's
         position is not substantially upheld, as determined by the arbitrator,
         the expenses of the Executive (including, without limitation, fees and
         expenses payable to the AAA and the arbitrator, fees and expenses
         payable to witnesses, including expert witnesses, fees and expenses
         payable to attorneys and other professionals, expenses of the Executive
         in attending the hearings, costs in connection with obtaining and
         presenting evidence and costs of the transcription of the proceedings),
         as determined by the arbitrator, shall be reimbursed to him by the
         Company.

14.      Confidentiality: During the Employment Term, and except as otherwise
         required by law, the Executive shall not disclose or make accessible to
         any business, person or entity, or make use of (other than in the
         course of the business of the Company) any trade secrets, proprietary
         knowledge or confidential information, which he shall have obtained
         during his employment by the Company and which shall not be generally
         known to or recognized by the general public. All information regarding
         or relating to any aspect of either the Company's business, including
         but not limited to that relating to existing or contemplated business
         plans, activities or procedures, current or prospective clients,
         current or prospective contracts or other business arrangements, or any
         other information acquired because of the Executive's employment by the
         Company, shall be conclusively presumed to be confidential; provided
         however, that Confidential Information shall not include any


                                       23



         information known generally to the public (other than as a
         result of unauthorized disclosure by the Executive) or any specific
         information or type of information generally not considered information
         disclosed by the Company or any officer thereof to a third party
         without restrictions on the disclosure of such information. The
         Executive's obligations under this Section 14 shall be in addition to
         any other confidentiality or nondisclosure obligations of the Executive
         to the Company at law or under any other agreements. 

15.      Other Matters:
     
         (a) Entire Agreement: This Agreement constitutes the entire agreement
         between the Company and the Executive relating to the subject matter
         hereof, and supersedes any previous agreements, commitments and
         understandings, written or oral, with respect to the matters provided
         herein. As used in this Agreement, terms such as "herein," "hereof,"
         "hereto" and similar language shall be construed to refer to this
         entire instrument and not merely the paragraph or sentence in which
         they appear, unless so limited by express language.

         (b) Assignment: Except as set forth below, this Agreement and the
         rights and obligations contained herein shall not be assignable or
         otherwise transferable by either party to this Agreement without the
         prior written consent of the other party to this Agreement.
         Notwithstanding the foregoing, any amounts owing to the Executive upon
         his death shall inure to the benefit of his heirs, legatees, personal
         representatives, executor or administrator.

         (c) Notices: Any and all notices provided for under this Agreement
         shall be in writing and hand delivered or sent by first class
         registered or certified mail, postage prepaid,


                                       24

         return receipt requested, addressed to the Executive at his residence
         or to the Company at its usual place of business, and all such notices
         shall be deemed effective at the time of delivery or at the time
         delivery is refused by the addressee upon presentation.

         (d) Amendment/Waiver: No provision of this Agreement may be amended,
         waived, modified, extended or discharged unless such amendment, waiver,
         extension or discharge is agreed to in writing signed by both the
         Company and the Executive.

         (e) Applicable Law: This Agreement and the rights and obligations of
         the parties hereunder shall be construed, interpreted, and enforced in
         accordance with the laws of the State of New York (applicable to
         contracts to be performed wholly within such State).

         (f) Severability: The Executive hereby expressly agrees that all of the
         covenants in this Agreement are reasonable and necessary in order to
         protect the Company and its business. If any provision or any part of
         any provision of this Agreement shall be invalid or unenforceable under
         applicable law, such part shall be ineffective only to the extent of
         such invalidity or unenforceability and shall not affect in any way the
         validity or enforceability of the remaining provisions of this
         Agreement, or the remaining parts of such provision.

         (g) Successor of Interests: In the event the Company merges or
         consolidates with or into any other corporation or corporations, or
         sells or otherwise transfers substantially all of its assets to another
         corporation, the provisions of this Agreement shall be binding upon and
         inure to the benefit of the corporation surviving or resulting from the
         merger or consolidation or to which the assets are sold or transferred
         and, prior to the


                                       25

         consummation of any such event, the Company shall obtain the express
         written assumption of this Agreement by the other corporation (other
         than in the case of a merger after which the Company is the surviving
         entity). All references herein to the Company refer with equal force
         and effect to any corporate or other successor of the corporation that
         acquires directly or indirectly by merger, consolidation, purchase or
         otherwise, all or substantially all of the assets of the Company.

         (h) No Mitigation: The Executive shall not be required to mitigate
         amounts payable pursuant to Section (12) hereof by seeking other
         employment or otherwise.


16.      Condition Subsequent: This Agreement shall be null and void and of no
         effect if the Spin-off is not consummated on or before March 1, 1997.

17.      Indemnification: The Company shall indemnify the Executive to the full
         extent permitted by law and the By-laws of the Company for all
         expenses, costs, liabilities and legal fees which the Executive may
         incur in the discharge of all his duties hereunder, including, without
         limitation, the right to be paid in advance by the Company for his
         expenses in defending a civil or criminal action, proceeding or
         investigation prior to the final disposition thereof. The Executive
         shall be insured under the Company's Directors' and Officers' Liability
         Insurance Policy as in effect from time to time. Notwithstanding any
         other provision of this Agreement to the contrary, any termination of
         the Executive's employment or of this Agreement shall have no effect on
         the continuing operation of this Section (17).


                                       26
