         WHEREAS, it is anticipated that the Company will shortly become a
publicly traded company, independent of its present parent, Pennzoil Company
("Pennzoil"), through a spinoff from Pennzoil followed immediately by a merger
of the Company with Quaker State Company in which the Company is the survivor
and shall be named Pennzoil-Quaker State Company (such events hereinafter the
"Transaction");

         WHEREAS, the Company wishes to engage Employee now regardless of

         NOW, THEREFORE, in consideration of the premises and the agreements
hereinafter contained, the parties hereto agree as follows:

Paragraph 18 ("Employment Term"). The employment of Employee shall be subject to
the other terms and conditions of this Agreement. Employee agrees to devote his

after the closing date of the Transaction, at the principal executive offices of
Pennzoil-Quaker State Company, wherever such offices shall be situated, subject

this Agreement.

         2. Salary Compensation. Effective as of the date hereof and during the
Employment Term the Company hereby agrees to pay as current salary compensation

                                       -2-
   3
$500,000 on an annualized basis but payable in biweekly installments of
$19,230.77 each. The salary amounts described in the next preceding sentence
shall be reviewed annually by the Compensation Committee of the Company's Board
of Directors with a view to consideration of appropriate merit increases but may
not be decreased during the Employment Term.

         3. Stock Option Grants. Effective as of the closing date of the
Transaction, the Company shall grant to Employee nonqualified stock options to
purchase shares of Common Stock of Pennzoil-Quaker State Company, par value
$_____ per share ("Common Stock"), with an aggregate grant value of $3,700,000
based on a grant price ("Grant Price") equal to the average for each of the five
trading days following the date of the Transaction of the mean between the
highest and the lowest sale prices per share of Common Stock on the New York
Stock Exchange (Composite Tape) (such mean being the "NYSE Price") on each such
day ("Initial Stock Option"). The actual number of shares subject to the Initial
Stock Option shall be determined by dividing 3,700,000 by the Grant Price. The
terms and conditions of such Initial Stock Option shall be substantially similar
to those applicable to options previously granted under Pennzoil's stock option
plans to key executive employees of Pennzoil and shall include (i) a term of ten

options shall be exercisable, (iii) provision for exercisability of all options
in the event of death, retirement or disability, (iv) acceleration of all
options in the event of a change in control of the Company and (v) other terms
no less favorable to Employee than those reflected in this Agreement or in the

                                       -3-
   4
parties hereto on terms consistent with the foregoing; provided that the option
shall be effective as of the closing date of the Transaction in accordance with
the terms and conditions contained herein, irrespective of whether a stock
option agreement has been executed by the parties. Employee shall be granted
additional stock options in an amount and with a frequency consistent with the
Company's stock option grant policy under the Company's applicable long-term
incentive plans with respect to similarly situated Company employees. Employee's

of the Common Stock for the day preceding the date of grant.

         4. Conditional Stock Awards. Employee shall participate in the
Company's grants of Common Stock Units in an amount and with a frequency
consistent with the Company's grant policy under the Company's applicable
long-term incentive plans with respect to similarly situated Company employees.

least equal to the number determined by dividing 185,000 by the NYSE Price of
the Common Stock for the day preceding the date of grant.

         5. Executive Severance Plan. Pennzoil agrees to cover Employee under
Pennzoil's Executive Severance Plan as of the date hereof and to continue

to other Pennzoil salaried employees.

         9. Savings Plan. Employee shall participate in Pennzoil's Savings and
Investment Plan on the same terms and conditions as are applicable to other
Pennzoil salaried employees.

         10. Other Benefits. Except as is specifically provided herein to the
contrary, Employee shall be entitled to participate as of the date hereof in all
other benefit plans, programs or practices generally applicable to salaried
employees and to those special benefit programs, plans and practices applicable

         12. Temporary Lodging and Commuting Expense Reimbursements. The 
Company and Employee agree to endeavor in good faith to negotiate mutually
agreeable terms for the Company's reimbursement of Employee's temporary lodging
and commuting expenses.

         13. Perquisites. Effective as of the date hereof, the Company shall
afford to Employee perquisites consistent with the level of compensation and
responsibility of Employee, such perquisites to be continued uninterrupted
except to the extent that the Board of Directors determines that prospective
adjustment to perquisite policy is appropriate for similarly situated employees.

         14. Annual Paid Vacation. Employee shall be entitled to four weeks of
paid vacation annually.

         15. Annual and Long Term Performance Incentive Plan. Effective as of
January 1, 1999, the Company shall afford to Employee participation in both an
annual performance incentive program ("Annual Plan") and a long term incentive
program ("LTIP") with terms and conditions substantially in accordance with
those described on Exhibit D attached hereto. Employee's target annual bonus
under the Annual Plan shall be 65% of then current salary. Employee's target
LTIP payments shall be, for each LTIP cycle, 74% of annualized salary (as in
effect at the time of payout, if any, under the LTIP).

         16. Change in Control. For purposes of this Agreement, a change in
control of Pennzoil shall conclusively be deemed to have occurred (i) if the
Board of Directors of Pennzoil determines by resolution that a change in control
which has the reasonable likelihood of depriving key employees of benefits they
otherwise would have earned, by depriving key employees of the opportunity to
fulfill applicable service and age prerequisites to benefits or otherwise has
occurred, or (ii) upon the occurrence of an event specified for such purposes as
a change in 


                                       -6-

   7
control which has the reasonable likelihood of depriving key employees of
benefits they otherwise would have earned, by depriving key employees of the
opportunity to fulfill applicable service and age prerequisites to benefits or
otherwise, by resolution of the Board of Directors of Pennzoil adopted not more
than 60 days prior to the occurrence of such event. The Effective Date of a
change in control shall be (x) in the case of such a change in control described
as specified in clause (i) of the preceding sentence, the date (not more than 30
days prior to the date on which the Board of Directors of Pennzoil makes the
determination) the Board of Directors of Pennzoil determines as the date on
which the change in control has occurred, or (y) in the case of such a change in
control determined as specified in clause (ii) of the preceding sentence, the
date of occurrence of the event specified by the Board of Directors of Pennzoil
as constituting such change in control. The Transaction shall not constitute a
change in control of Pennzoil or the Company.

         17. Disability. In the event Employee suffers a Disability and
qualified for benefits under the Company's Supplemental Disability Plan during
the Employment Term, salary payments under Paragraph 2 shall be discontinued;
provided, however, Employee shall be entitled to the Disability and other
benefits provided by the Company and consistent with Paragraph 10 of this
Agreement. For purposes of this Agreement, "Disability" shall have the meaning
set forth in Pennzoil's Supplemental Disability Plan.

         18. Termination of Employment.

             (a) By the Company for Due Cause.

                 I. Nothing herein shall prevent the Company from terminating 
             Employee for Due Cause in which event the Employment Term shall
             end and Employee shall continue to receive salary and benefit
             coverages 


                                       -7-

   8
             provided for in this Agreement only through the period ending with
             the date of such termination as provided in this Paragraph 18(a).
             Any other rights and benefits Employee may have under other
             employee benefit plans and programs of the Company, generally,
             shall be determined in accordance with the terms of such plans and
             programs. The term "Due Cause" as used herein, shall mean (x)
             Employee has committed a willful serious act, such as
             embezzlement, against the Company intending to enrich himself at
             the expense of the Company or has been convicted of a felony
             involving moral turpitude or (y) Employee, in carrying out his
             duties hereunder, has been guilty of (i) willful, gross neglect or
             (ii) willful, gross misconduct resulting in either case in
             material harm to the Company.

                 II. Notwithstanding the foregoing, no termination of Employee's
             employment by the Company shall be treated as for Due Cause or be
             effective until and unless all of the steps described in
             subparagraphs (i) through (iii) below have been complied with:

                 (i) Notice of intention to terminate for Due Cause has been
             given by the Company within 120 days after the Board of Directors
             of the Company learns of the act, failure or event (or latest in a
             series of acts, failures or events) constituting "Cause";

                 (ii) The Board of Directors of the Company has voted (at a
             meeting of the Board duly called and held as to which termination
             of Employee is an agenda item) to terminate Employee for Due Cause
             after Employee has been given notice of the particular acts or
             circumstances 


                                       -8-

   9
             which are the basis for the termination for Due Cause and has been
             afforded at least 20 days notice of the meeting and an opportunity
             to present his position in writing; and

                 (iii) The Board of Directors of the Company has given a Notice
             of Termination to Employee within 20 days of such Board meeting.

         The Company may suspend Employee with pay at any time during the period
         commencing with the giving of notice to Employee under clause (i) above
         until final Notice of Termination is given under clause (iii) above.
         Upon the giving of notice as provided in clause (iii) above, no further
         payments shall be due Employee.

             (b) By Death or Disability.

                 I. In the event of the death of Employee during the Employment
             Term, the policies and plans of the Company applicable to Employee
             shall govern all payments to be made to Employee's estate or
             beneficiaries and no further payments shall be made to Employee
             pursuant to Paragraph 2 of this Agreement, this Agreement shall
             terminate and all amounts accrued for the benefit of Employee on
             that date shall be paid to Employee's estate or beneficiaries. Any
             death benefit under life insurance or other benefit programs
             covering Employee shall be determined and paid in accordance with
             the provisions of such policies and programs and the Initial Stock
             Option shall be vested, or if not theretofore granted, shall be
             granted as provided herein, and in either case remain outstanding
             and exercisable for one year after death.


                                       -9-

   10
                 II. If Employee's employment is terminated by reason of
             Disability, the policies and plans of the Company applicable to
             Employee shall govern all payments to be made to Employee and the
             Initial Stock Option shall be vested or if not theretofore
             granted, shall be granted as provided herein and in either case
             remain outstanding and exercisable until the earlier to occur of
             death or one year after termination of employment.

             (c) Voluntarily By Employee. Employee may terminate his employment
         and the Employment Term under this Agreement other than for Good Reason
         by providing 30 days notice to Company in which event Employee shall be
         entitled only to those benefits as are specifically provided under the
         terms of a particular benefit plan or program and salary payments under
         Paragraph 2 shall immediately cease.

             (d) By Company Other Than For Due Cause. If Employee's employment
         under this Agreement is terminated by the Company for any reason other
         than as provided in Paragraph 18(a) hereof and other than after a
         change in control of the Company (as defined in Paragraph 16), the
         Company shall (i) pay to Employee in a lump sum amount twice the amount
         of current annualized salary compensation being paid to Employee under
         Paragraph 2, (ii) permit Employee's and Employee's dependents continued
         participation in Company medical plans previously available to Employee
         for a period of two years following such termination and (iii) cause
         the Initial Stock Option granted pursuant to Paragraph 3 to be fully
         vested and immediately exercisable for a period of 730 days following
         such termination of employment. Any other stock options will continue
         to vest and


                                      -10-

   11
         become exercisable determined as if Employee had remained employed for
         two years following his actual termination of employment. Conditional
         Stock Awards shall be prorated by multiplying each such award by a
         fraction, the numerator of which is the number of complete calendar
         months elapsing between January 1 of the initial year of the award and
         the date that is two years from termination of employment and the
         denominator of which is 60, but such prorated awards shall be paid out
         only at the end of the original award period. Any LTIP award shall be
         prorated in the same manner as Conditional Stock Awards (but using a
         denominator of 36) and paid out as soon as is practicable after the end
         of the three-year performance period. In addition, Employee's interests
         in the Excess Benefits Agreements described in Paragraph 6 and the
         qualified plans described in Paragraphs 8 and 9 hereof shall be fully
         vested and nonforfeitable as of such termination and all service
         requirements for early retirement shall be treated as satisfied and the
         Company shall pay in a cash lump sum to Employee upon such termination
         an amount equal to the benefits under such qualified plans otherwise
         forfeitable which cannot be paid pursuant to those plans.

             (e) By Employee For Good Reason. Anything herein to the contrary
         notwithstanding, if the Company (i) demotes Employee to a lesser
         position than provided in Paragraph 1 or, if the Transaction does not
         occur, Paragraph 27; (ii) causes a material change in the nature or
         scope of the authorities, powers, functions, duties, or
         responsibilities attached to Employee's position as provided in
         Paragraph 1 or, if the Transaction does not occur, Paragraph 27; (iii)
         decreases Employee's salary below the level provided for by the terms
         of Paragraph 2 (taking


                                      -11-

   12
         into account increases made from time to time in accordance with such
         Paragraph 2); (iv) materially reduces Employee's benefits under any
         executive compensation or employee benefit plan, program, or
         arrangement of the Company (other than a change made prior to a change
         in control that affects all of the Company's senior executive officers
         alike) from the level in effect upon Employee's commencement of
         participation on or after the date hereof; (v) fails to elect or
         maintain Employee as a member of the Company's board of directors if
         required to do so under Paragraph 1; (vi) fails to locate Employee's
         office at the Company's principal executive office; (vii) fails to
         obtain the assumption in writing of the obligation to perform this
         Agreement by any successor to all or substantially all of the assets of
         the Company within 60 days after a merger, consolidation, sale, or
         similar transaction unless such assumption occurs by operation of law;
         or (viii) commits any other material breach of this contract, then,
         such action (or inaction) by the Company, unless consented to in
         writing by Employee, shall give Employee the right to treat such action
         as a termination of Employee's employment by the Company without Due
         Cause and to receive the compensation and benefits provided pursuant to
         Paragraph 18(d) above. Notwithstanding the preceding sentence, within
         60 days of learning of the action (or inaction) described herein as the
         basis for a constructive termination of employment, Employee shall
         (unless he gives written consent thereto) advise the Company in
         writing, that the action (or inaction) constitutes a basis for
         termination of his employment pursuant to this Paragraph 18(e) in which
         event the Company shall have 60 days in which to correct such action or
         inaction and if the Company does so correct such action (or


                                      -12-

   13
         inaction) Employee shall not be entitled to terminate his employment
         under this Paragraph 18(e) as a result of such action (or inaction). If
         the Company fails to correct such action or inaction within such 60-day
         period, Employee may terminate his employment for Good Reason within 30
         days of the expiration of such period.

             (f) Following Change In Control of the Company. If Employee's
         employment is terminated within two years following a change in control
         of the Company by the Employee for Good Reason or by the Company for
         reasons other than death, Disability or Due Cause, such termination
         shall be treated as a termination of employment by Company without Due
         Cause and thereupon Employee shall receive the cash and benefits
         described in Paragraph 18(d), plus any greater benefits provided under
         the Executive Severance Plan, without any duplication of benefits.

             (g) Expiration of Employment Term. Except as provided in Paragraph
         18(f), in the event this Agreement expires by its terms at the end of
         the initial Employment Term and the Company has not, at least six
         months prior to such date, given Employee written notice of its
         intention not to continue Employee's employment, either at will or
         pursuant to other mutually agreeable terms, the Company shall pay
         Employee a lump sum cash amount equal to the sum of (i) one times
         Employee's annualized salary compensation paid to Employee pursuant to
         Paragraph 2, plus (ii) (A) one twelfth of such annualized salary
         compensation times (B) a number equal to six minus the number of months
         of notice actually provided to Employee prior to the expiration of the
         Employment Term.


                                      -13-
   14
             (h) Company Benefits Upon Termination. Employee shall also be
         entitled in all events upon termination to receive the benefits to
         which he is entitled, if any, under the Company's plans and programs
         referenced herein or otherwise in effect from time to time.

             (i) Effect on Agreement. Termination of employment or the
         Employment Term as used herein shall not constitute a termination of
         this Agreement and the provisions hereof shall survive until the
         respective rights of the Company and Employee have been discharged.

         19. Noncompetition Agreement. The Company and Employee agree to
endeavor in good faith to negotiate a form of noncompetition agreement with a
one year term mutually agreeable to the Company and Employee, which Employee
shall execute in favor of the Company if Employee's employment is terminated
pursuant to Paragraph 18(d) or Paragraph 18(e).

         20. Prohibition Against Assignment. The right of Employee to benefits
under this Agreement shall not be assigned, transferred, pledged or encumbered
in any way and any attempt at assignment, transfer, pledge, encumbrance or other
disposition of such benefits shall be null and void and without effect.

         21. Binding Effect. This Agreement shall be binding upon and enure to
the benefit of the Company, its successors and assigns, and Employee, his heirs,
executors, administrators and legal representatives.
