                              EMPLOYMENT AGREEMENT

         AGREEMENT, dated this lst day of January, 2002 (the "Agreement"),
between Heidrick & Struggles, Inc., a Delaware corporation, and any successor
(the "Employer") and Knox J. Millar (the "Employee"). The parties hereby agree,
as follows:

         1. Employment. The Employer shall employ the Employee as Chief Human
Resources Officer and the Employee hereby accepts such position and agrees to
serve the Employer in such capacity during the employment period fixed by
Section 3 hereof (the "Employment Period"). The Employee shall report to the
Chief Executive Officer of the Employer. The Employee's duties and
responsibilities shall be such duties and responsibilities as are consistent
with the position of Chief Human Resources Officer of the Employer. The Employee
shall devote substantially all of his business time and attention to the
performance of his duties and responsibilities hereunder.

         2. Compensation.

            (a) Annual Base Salary. The Employer shall pay the Employee,
pursuant to the Employer's normal and customary payroll procedures, a base
salary of $500,000 per annum (the "Annual Base Salary").

            (b) Annual Bonus. In addition to the Annual Base Salary, during
the Employment Period, the Employee may receive an annual bonus (the "Annual
Bonus"), based on the achievement of performance objectives, which shall be
determined by the Compensation Committee of the Board of Directors of the
Employer (the "Board").

            (c) Incentive Compensation; Benefit Plans. Commencing in January
2002, the Employee shall participate in the Employer's Annual Bonus Plan, Change
in Control Severance Plan and Severance Plan. In addition, during the Employment
Period (i) the Employee shall be entitled to participate in all other savings
and retirement plans, practices, policies and programs of the Employer which are
made available generally to other employees of the Employer and (ii) the
Employee and/or the Employee's family, as the case may be, shall be eligible for
participation in, and shall receive all benefits under, all welfare benefit
plans, practices, policies and programs provided by the Employer (including,
without limitation, vacation, medical, prescription, dental, disability, life
insurance, group life insurance, accidental death and travel accident insurance
plans and programs, together the "Benefit Plans") which are made available
generally to other employees of the Employer. The Employer's Physical

         3. Employment Period.

            The Employment Period shall commence on January 1, 2002 (the
"Effective Date") and shall end July 1, 2003. Notwithstanding the foregoing, the
Employee's employment hereunder may be terminated during the Employment Period
upon the earliest to occur of the following events:

            (a) Death. The Employee's employment hereunder shall terminate
immediately upon his death.

            (b) Disability. The Employer may terminate the Employee's employment
hereunder for "Disability," which shall mean (i) a physical or mental incapacity
of the Employee which entitles the Employee to benefits under the long-term
disability plan applicable to the Employee and maintained by the Employer; or
(ii) in the event that no such long-term disability plan is maintained by the
Employer, the Employee has been unable to perform his duties hereunder for a
period of 180 days within any twelve-month period as a result of the Employee's
incapacity due to physical or mental illness.

            (c) Cause. The Employer may terminate the Employee's employment
hereunder for Cause. For purposes of this Agreement, the term "Cause" shall mean
(i) fraud, or the embezzlement or misappropriation of funds or property of the
Employer or any of its affiliates by you, the conviction of, or the entrance of
a plea of guilty or nolo contendere by Employee, to a felony, or a crime
involving moral turpitude; (ii) neglect, misconduct or willful malfeasance which
is materially injurious to the Employer or any of its affiliates; or (iii)
willful failure or refusal to perform your duties, or a willful, material breach
of contract. If, subsequent to the Employee's termination of services hereunder
for other than Cause, it is discovered that the Employee's services could have
been terminated for Cause, the Employee's services shall, at the election of the
Employer, be deemed to have been terminated for Cause retroactively to the date
the events giving rise to Cause occurred.

            (d) Good Reason. The Employee may terminate his employment
hereunder for Good Reason (and such termination shall be treated as if it were a
termination by the Employer without Cause, and not a voluntary termination by
the Employee). "Good Reason" shall mean (i) a diminution of the amount of the
Employee's base salary or target bonus or benefits; (ii) termination of the
Employee's participation in Tier One of the Employer's Change in Control
Severance Plan or the Employee's participation in the Top Management level of
the Employer's Severance Plan; (iii) the elimination of the Employee's position
or a diminution of responsibilities associated with the Employee's position; or
(iv) a change in the location of the Employee's principal place of employment
more than 50 miles from its initial location without the Employee's approval.

                                      -2-

<PAGE>

            Notwithstanding the foregoing, an isolated and inadvertent action
taken in good faith and which is remedied by the Employer within 30 days after
receipt of written notice thereof given by the Employee shall not constitute
Good Reason.

            (e) Without Cause. The Employer may terminate the Employee's
employment hereunder without Cause.

            (f) Without Good Reason. The Employee may terminate his employment
hereunder without Good Reason, provided that the Employee provides the Employer
with notice of his intent to terminate his employment without Good Reason at
least six months in advance of the Date of Termination; provided, however, that
the Employer may treat such notice as a resignation and accept it prior to the
expiration of six months at the Employer's sole discretion.

         4. Expense Reimbursement. During the Employment Period, the Employer
shall reimburse the Employee for all reasonable business expenses upon the
presentation of statements of such expenses in accordance with the Employer's
policies and procedures now in force or as such policies and procedures may be
modified with respect to all employees of the Employer. The Employer shall pay
or reimburse the Employee on a grossed-up basis for two business class round
trip tickets per year between New York and Europe and accommodations in
accordance with the Employer's travel policy in effect at the time. The Employer
shall also pay or reimburse the Employee for the cost of a health club.

         5. Termination Payments.

            A. In the event of termination of the Employee's employment during
the Employment Period:

                (i)  by the Employer without Cause (pursuant to Section 3(f));
                     or

                (ii) by the Employee for Good Reason (pursuant to Section 3(d))

then, the Employee shall be entitled to the following payments:

                (a)  Annual Base Salary through the Date of Termination (to the
                     extent not paid) within 10 days following the Date of
                     Termination;

                (b)  Earned but unpaid Annual Bonus in respect of the year ended
                     prior to the Date of Termination;

                                      -3-

<PAGE>

                (c)  A pro rata portion of his target Annual Bonus (which target
                     shall not be less than $500,000) based upon the number of
                     months worked in the year in which the Date of Termination
                     occurs;

                (d)  Severance pay pursuant to the Top Management level of the
                     Employer's Severance Plan;

                (e)  Amounts vested under the terms of benefits plans in which
                     he is a participant under the terms thereof; and

                (f)  Unreimbursed expenses under Section 4 of this Agreement.

            B. The Employee shall not be entitled to any further payments or
benefits under this Agreement in respect of any termination of the Employee's
employment during the Employment Period by the Employer without Cause (pursuant
to Section 3(f)) or by the Employee for Good Reason (pursuant to Section 3(d)).
The payments and benefits provided in this Section 5A(a) and 5A(b) are subject
to and conditioned upon the Employee's compliance with the restrictive covenants
provided in Section 7 and shall be subject to and conditioned upon the Employee
executing a valid general release and waiver, waiving all claims the Employee
may have against the Employer, its successors, assigns, affiliates, employees,
officers and directors.

            C. In the event that the Employee's employment terminates at the
expiration of the Employment Period without renewal, then the Employee shall be
entitled to a pro rata portion of his target Annual Bonus (which target shall
not be less than $500,000) based upon the number of months worked in the year in
which the Date of Termination occurs and the Employee shall be entitled to
continue his participation in the Employer's benefit plans (to the extent he is
a participant on the date of expiration) for six months after expiration of the
Employment Period.

            D. If the Employee's employment is terminated during the Employment
Period by the Employer for Cause, by the Employee without Good Reason, or as a
result of the Employee's death or Disability pursuant to Sections 3(c), 3(g),
3(a) and 3(b), respectively, the Employer shall pay the amounts referred to in
Section 5A(a) and 5A(b) to the Employee (or the Employee's estate or legal
representative in the event of the Employee's death) within thirty days
following the Date of Termination and the Employee shall not be entitled to any
further payments or benefits under this Agreement.

            E. The Employer shall forgive the $700,000 principal amount of the
loan made to the Employee in June 2001 in accordance with the terms of the
Promissory Note attached hereto.

                                      -4-

<PAGE>

         6. Non-Exclusivity of Rights. Any vested benefits and other amounts
that the Employee is otherwise entitled to receive under any Benefit Plan or
other employee benefit plan, policy, practice or program of the Employer shall
be payable in accordance with such Benefit Plan or other employee benefit plan,
policy, practice or program as the case may be, except as explicitly modified by
this Agreement.

         7. Confidentiality of Information; Duty of Non-Disclosure; Non-
Competition; Non-Solicitation.

            (a) Confidential Information; Duty of Non-Disclosure. The
Employee's employment under this Agreement necessarily involves his access to
and understanding of certain trade secrets and confidential information
pertaining to the business of the Employer and its affiliates. During the
Employment Period and thereafter, he will not, directly or indirectly, without
the prior written consent of the Employer, disclose or use for the benefit of
any person, corporation or other entity, or for himself any and all files, trade
secrets or other confidential information concerning the internal affairs of the
Employer or its affiliates, including, but not limited to, information
pertaining to its clients, services, products, earnings, finances, operations,
methods or other activities; provided, however, that the foregoing shall not
apply to information which is of public record or is generally known, disclosed
or available to the general public or the industry generally (other than as a
result of the Employee's breach of this Section 7(a)). Notwithstanding the
foregoing, the Employee may disclose such information as is required by law
during any legal proceeding or to the Employee's personal representatives and
professional advisers and, with respect to such personal representatives and
professional advisers, the Employee shall inform them of his obligations
hereunder and take all reasonable steps to ensure that such professional
advisers do not disclose the existence or substance thereof. Further, the
Employee shall not, directly or indirectly, remove or retain, without the
express prior written consent of the Employer, and upon termination of
employment for any reason shall return to the Employer, any records, computer
disks, computer printouts, business plans or any copies or reproductions
thereof, or any information or instruments derived therefrom, arising out of or
relating to the business of the Employer and its affiliates or obtained as a
result of his employment.

            (b) Non-Competition. During the Employment Period and for a period
of six months after the termination of the Employee's employment with the
Employer, the Employee shall not work for or provide services to a principal
competitor of the Employer and its affiliates in a substantially similar
function as the Employee held with the Employer during the two-year period prior
to the Employee's termination of employment with the Employer.

            (c) Non-Solicitation. During the Employment Period and for a period
of one year after the termination of the Employee's employment with the
Employer, the Employee shall not (i) hire, solicit for hire, or assist any other
person in soliciting or

                                      -5-

<PAGE>

hiring any employment candidate with whom the Employee has had contact while
employed by the Employer during the two years prior to such termination or (ii)
directly or indirectly solicit or hire, or assist any other person in soliciting
or hiring, any employee of the Employer and its affiliates (as of the date of
the Employee's termination of employment) or any person who, as of such date,
was in the process of being recruited by the Employer and its affiliates, or
induce any such employee to terminate his or her employment with the Employer
and its affiliates

             (d) Remedies. The parties hereto hereby agree that it is impossible
to measure in money the damages which will accrue to the Employer by reason of a
failure by the Employee to perform any of his obligations under this Section 7
and the Employee acknowledges that such obligations are a material condition to
the Employer's decision to enter into this Agreement. Accordingly, if the
Employer institutes any action or proceeding to enforce the provisions hereof,
to the extent permitted by applicable law, the Employee hereby waives the claim
or defense that the Employer has an adequate remedy at law, and the Employee
shall not urge in any such action or proceeding the defense that any such remedy
exists at law. The restrictive covenants in this Section 7 are in addition to
any rights the Employer may have in law or at equity or under any other
agreement. In the event that a court of competent jurisdiction finds the
Employee to be in violation of the provisions of Sections 7(b) or 7(c), the
non-competition and/or non-solicitation period shall be extended by the period
of time during which such court found the Employee to have been in such
violation. The foregoing shall not prejudice the Employer's right to require the
Employee to account for and pay over to the Employer any profit obtained by the
Employee as a result of any transaction constituting a breach of this Section 7.

             (e) Survival of Covenants. This Section 7 shall survive the
termination of the Employment Period.

         8.  Arbitration. This Agreement contains our entire understanding and
can be amended only in writing and signed by the Employee and Chief Executive
Officer of the Employer. The Employee specifically acknowledges that no promises
or commitments have been made to him that are not set forth in this Agreement.

         Any controversy or claim arising out of or relating to this Agreement
or for the breach thereof, or Employee's employment, including without
limitation any statutory claims (for example, claims for discrimination
including but not limited to discrimination based on race, sex, sexual
orientation, religion, national origin, age, marital status, handicap or
disability; and claims relating to leaves of absence mandated by state or
federal law), breach of any contract or covenant (express or implied), tort
claims, violation of public policy or any other alleged violation of statutory,
contractual or common law rights (and including claims against officers,
directors, employees or agents of the Employer) if not otherwise settled between
the parties, shall be conclusively settled by arbitration to be held in New
York, New York, in accordance with the American Arbitration Association's
Employment Dispute Resolution Rules (the "Rules"). Arbitration shall be the
parties' exclusive

                                      -6-

<PAGE>

remedy for any such controversies, claims or breaches. The parties agree they
shall not seek any award for punitive damages for any claims they may have under
this Agreement. The parties also consent to personal jurisdiction in New York,
New York with respect to such arbitration. The award resulting from such
arbitration shall be final and binding upon both parties. Judgment upon said
award may be entered in any court having jurisdiction.

         Employee and the Employer hereby waive the right to pursue any claims,
including but not limited to employment termination - related claims, through
civil litigation outside the arbitration procedures of this provision, unless
otherwise required by law. Employee and the Employer each have the right to be
represented by counsel with respect to arbitration of any dispute pursuant to
this paragraph. The arbitrator shall be selected by agreement between the
parties, but if they do not agree on the selection of an arbitrator within 30
days after the date of the request for arbitration, the arbitrator shall be
selected pursuant to the Rules.

         In the event of any arbitration hereunder, the parties agree each shall
bear its or his own attorneys' fees and costs associated with or arising from
such arbitration or other proceeding.

         9.  Miscellaneous.

             (a) Notices. Any notice to be given hereunder shall be given in

             (b) Entire Agreement. This Agreement constitutes the entire
agreement among the parties hereto with respect to the Employee's employment.
This Agreement expressly supersedes the Agreement, dated July 7, 2000, between
the Employer and the Employee and such Agreement shall be of no further force
and effect.

             (c) Modification or Amendment; Waiver. This Agreement may be
amended only by an instrument in writing signed by the parties hereto, and any
provision hereof may be waived only by an instrument in writing signed by the
party or parties against whom or which enforcement of such waiver is sought. The
failure of any party hereto at any time to require the performance by any other
party hereto of any provision hereof shall in no way affect the full right to
require such performance at any time thereafter, nor shall the waiver by any
party hereto of a breach of any provision hereof be taken or held to be a waiver
of any succeeding breach of such provision or a waiver of the provision itself
or a waiver of any other provision of this Agreement.

Agreement, and if one or more provisions hereof are declared invalid, the
remaining provisions shall nevertheless remain in full force and effect. If any
provision of this Agreement or portion thereof is so broad, in scope or duration
or otherwise, as to be unenforceable, such provision or portion thereof shall be
interpreted to be only so broad as is enforceable.

             (f) Tax Withholding. The Employer may withhold from any amounts
payable to the Employee hereunder all federal, state, city or other taxes that
the Employer may reasonably determine are required to be withheld pursuant to
any applicable law or regulation.

             (g) Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without
reference to its principles of conflicts of law.

             (h) Counterparts. This Agreement may be executed in several
counterparts, each of which shall be deemed an original, but all of which shall
constitute one and the same instrument.

             (i) Headings. The headings in this Agreement are inserted for
convenience of reference only and shall not be a part of or control or affect
the meaning of any provision hereof.

                              EMPLOYMENT AGREEMENT

          AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the "Agreement") effective

"Executive").

          WHEREAS, Executive became the Executive Vice-President and Chief
Financial Officer of the Company on February 1, 2002 and on that date Executive
and the Company entered into an Employment Agreement; and

          WHEREAS, Executive and the Company desire to amend and restate that
agreement in its entirety.

          1. Term of Employment. Subject to the provisions of Section 8,
Executive shall be employed by the Company for a period commencing on June 1,
2002 ("Start Date") and ending on June 1, 2005 (the "Employment Term") on the

          2. Position.

               a.   During the Employment Term, Executive shall serve as the
Executive Vice-President and Chief Financial Officer of the Company. In such
position, Executive shall have such duties and authority that are customary for
chief financial officers of corporations of the size, type and nature of the
Company, and as shall be determined from time to time by the Chief Executive
Officer and/or Board of Directors of the Company (the "Board").

               b.   During the Employment Term, Executive shall devote
Executive's full business time and best efforts to the performance of
Executive's duties hereunder and shall not engage in any other business,
profession or occupation for compensation or otherwise which would conflict or
interfere with the rendition of such services either directly or indirectly,
without the prior written consent of the Board; provided that nothing herein
shall preclude Executive (i) from continuing to serve on any board of directors
or trustees of any business corporation or any charitable organization and (ii)
subject to the prior written approval of the Board, which approval shall not be
unreasonably withheld, from accepting appointment to any board of directors or
trustees of any business corporation or any charitable organization; provided in
each case, and in the aggregate, that such activities do not materially conflict
or interfere with the performance of Executive's duties hereunder or conflict
with Section 9.

          3. Base Salary. During the Employment Term, the Company shall pay
Executive a base salary at the annual rate of $250,000, payable in regular
installments in accordance with the Company's usual payment practices. Executive
shall be entitled to such increases in Executive's base salary, if any, as may
be determined from time to time in the sole discretion of the Board. Executive's
annual rate of base salary, as in effect from time to time, is hereinafter
referred to as the "Base Salary."

          4. Annual Bonus. With respect to each fiscal year of the Company
ending during the Employment Term, Executive shall be eligible to earn an annual
bonus award (an "Annual Bonus") if net earnings per share to common shareholders
of the Company, calculated on a fully diluted basis and according to GAAP, as
determined by the Company's outside auditors, excluding the after-tax impact of
any extraordinary or special items that the Board determines in good faith are
not appropriately includable in the Annual Bonus calculation because such items
do not accurately reflect the operating performance of the Company, such as
inventory write ups and write downs, LIFO adjustments, asset purchase or
sale-related gains or losses and acquisition-related write downs ("Adjusted
EPS"), is at least equal to $2.50. Upon achievement of an Adjusted EPS of $2.50,
the Annual Bonus shall equal fifty percent (50%) of his Base Salary (the "Base
Bonus"). For each $0.01 increase in the applicable fiscal year's Adjusted EPS
above $2.50, the Annual Bonus shall be increased by an amount equal to one
percent of Executive's Base Salary, provided that in no event shall the Annual
Bonus be greater than three times Executive's Base Salary. The Annual Bonus
shall be paid to Executive within fifteen business days after the outside
auditors approve the Company's year-end earnings release. The Annual Bonus for
2002 only shall be calculated based on earnings from January 1, 2002 and the
resulting amount multiplied by 11/12ths, to arrive at the amount due for the
eleven months of 2002, so long as Executive is employed hereunder as of December
31, 2002. Annual Bonuses for subsequent full years during which Executive is
employed hereunder will reflect the full year (January 1 through December 31).

          5. Equity Arrangements. During the month of January in each of the
years 2003, 2004 and 2005, Executive shall receive a grant of options to
purchase not less than 25,000 shares of Company common stock at an exercise
price per share equal to Fair Market Value (as defined in the Plan) on the date
of grant (the "Annual Options"). Subject to Executive's continued employment
with the Company, such Annual Options will vest in equal installments on each of
the first three anniversaries of the date of grant, and will become fully vested
upon the occurrence of a Change in Control of the Company. Other terms and
conditions of the Annual Options shall be as set forth herein, in the Plan and
an option agreement between the Company and Executive. If the Company should,
prior to any Annual Option grant, be involved in any merger, reorganization,
stock split or spinoff or other similar event, the number of shares subject to
the Annual Options yet to be granted, as provided above, shall be adjusted on a
pro rata basis.

          6. Employee Benefits. During the Employment Term, Executive shall be
entitled to participate in the Company's employee benefit plans (which term does
not include bonus or incentive compensation plans), other than any non-qualified
pension plan or any severance pay plan, as in effect from time to time
(collectively "Employee Benefits"), on the same basis as those benefits are
generally made available to other senior executives of the Company. Executive
shall also be a participant in the Premcor Senior Executive Retirement Plan as
approved by the Board of Directors of the Company on April 2, 2002.

          7. Business Expenses. During the Employment Term, reasonable business
expenses incurred by Executive in the performance of Executive's duties
hereunder shall be reimbursed by the Company following presentation by Executive
of proof of such expenses, as and when reasonably required by the Company.

          8. Termination. The Employment Term and Executive's employment
hereunder may be terminated by the Company at any time and for any reason or by
Executive for Good Reason. Notwithstanding any other provision of this Agreement
(other than Section 13(h)), the provisions of this Section 8 shall exclusively
govern Executive's rights upon termination of employment with the Company and
its affiliates.

               a.   By the Company For Cause or By Executive Resignation Without
Good Reason.

            (i)   If Executive's employment is terminated by the Company for
Cause, or if Executive resigns without Good Reason, Executive shall be entitled
to receive:

               (A) the Base Salary through the date of termination;

               (B) any Annual Bonus earned but unpaid as of the date of
     termination for any previously completed fiscal year (including, if
     applicable, 2002);

               (C) reimbursement for any unreimbursed business expenses properly
     incurred by Executive in accordance with this Agreement prior to the date
     of Executive's termination;

               (D) such Employee Benefits, if any, as to which Executive may be
     entitled under the employee benefit plans of the Company (the amounts
     described in clauses (A) through (D) hereof being referred to as the
     "Accrued Rights"); and

               (E) any vested benefits as provided pursuant to the Premcor
     Senior Executive Retirement Plan, accrued in respect to any prior fiscal
     year.

          Following such termination of Executive's employment by the Company
for Cause or resignation by Executive without Good Reason, except as set forth
in this Section 8(a)(i), in the Plan and any applicable option agreement,
Executive shall have no further rights to any compensation or any other benefits
under this Agreement.

            (ii)  For purposes of this Agreement, "Cause" shall mean (A)
Executive's continued failure substantially to perform Executive's duties
hereunder (other than as a result of total or partial incapacity due to physical
or mental illness) for a period of 20 days following written notice by the
Company to Executive of such failure, (B) Executive's conviction of, or plea of
nolo contendere to a crime constituting (x) a felony under the laws of the
United States or any state thereof or (y) a misdemeanor involving moral
turpitude, (C) Executive's willful malfeasance or willful misconduct in
connection with Executive's duties hereunder or any act or omission which is
injurious to the financial condition or business reputation of the Company or
any of its subsidiaries or affiliates, other than an act or omission that was
committed or omitted by Executive in the good faith belief that it was in the
best interest of the Company or (D) Executive's breach of the provisions of
Sections 9 or 10 of this Agreement.

                                                                               4

               b.   Disability or Death.

            (i)   The Employment Term and Executive's employment hereunder shall
terminate upon Executive's death and may be terminated by the Company if
Executive becomes physically or mentally incapacitated and is therefore unable
for a period of six (6) consecutive months or for an aggregate of nine (9)
months in any twenty-four (24) consecutive month period to perform Executive's
duties (such incapacity is hereinafter referred to as "Disability"). Any
question as to the existence of the Disability of Executive as to which
Executive and the Company cannot agree shall be determined in writing by a
qualified independent physician mutually acceptable to Executive and the
Company. If Executive and the Company cannot agree as to a qualified independent
physician, each shall appoint such a physician and those two physicians shall
select a third who shall make such determination in writing. The determination
of Disability made in writing to the Company and Executive shall be final and
conclusive for all purposes of the Agreement.

            (ii)  Upon termination of Executive's employment hereunder for
either Disability or death, Executive or Executive's estate (as the case may be)
shall be entitled to receive:

               (A) the Accrued Rights;

               (B) a pro rata portion of any Annual Bonus, if any, that
     Executive would have been entitled to receive pursuant to Section 4 hereof
     in such year based upon the percentage of the fiscal year that shall have
     elapsed through the date of Executive's termination of employment, payable
     when such Annual Bonus would have otherwise been payable had Executive's
     employment not terminated; and

               (C) any vested benefits as provided in the Premcor Senior
     Executive Retirement Plan, accrued to the date of termination of
     employment.

          Following Executive's termination of employment due to death or
Disability, except as set forth in this Section 8(b)(ii), in the Plan and any
applicable option agreement, Executive shall have no further rights to any
compensation or any other benefits under this Agreement.

               c.   By the Company Without Cause or Resignation by Executive for
Good Reason.

            (i)   If Executive's employment is terminated by the Company without
Cause (other than by reason of death or Disability) or if Executive resigns for
Good Reason, Executive shall be entitled to receive:

               (A) the Accrued Rights;

               (B) subject to Executive's continued compliance with the
     provisions of Sections 9 and 10, payment, within 60 days of the date of
     termination of Executive's employment, of a lump sum equal to three times
     the sum of Executive's Base Salary and Base Bonus; and

<PAGE>

                                                                               5

               (C) the benefits as provided in the Premcor Senior Executive
     Retirement Plan, whether or not previously vested.

          Following Executive's termination of employment by the Company without
Cause (other than by reason of Executive's death or Disability) or by
Executive's resignation for Good Reason, except as set forth in this Section
8(c)(i), and the Plan and any applicable option agreement, Executive shall have
no further rights to any compensation or any other benefits under this
Agreement.

            (ii)  For purposes of this Agreement, "Good Reason" shall mean,
without Executive's consent, (A) the failure of the Company to pay or cause to
be paid Executive's Base Salary or Annual Bonus, when due hereunder, (B) any
substantial and sustained diminution in Executive's authority or
responsibilities from those described in Section 2 hereof or (C) relocation of
Executive's principal place of business by more than 30 miles, provided that
relocation to St. Louis, MO or Greenwich, CT shall not constitute Good Reason;
provided that the events described in clauses (A), (B) and (C) of this Section
8(c)(ii) shall constitute Good Reason only if the Company fails to cure such
event within 20 days after receipt from Executive of written notice of the event
which constitutes Good Reason; provided, further, that "Good Reason" shall cease
to exist for an event on the 90th day following the later of its occurrence or
Executive's knowledge thereof, unless Executive has given the Company written
notice thereof prior to such date.

               d.   Expiration of Employment Term.

            (i)   Election Not to Extend the Employment Term. In the event
either party elects not to extend the Employment Term pursuant to Section 1,
unless Executive's employment is earlier terminated pursuant to paragraphs (a),
(b) or (c) of this Section 8, Executive's termination of employment hereunder
(whether or not Executive continues as an employee of the Company thereafter)
shall be deemed to occur on the close of business on the day immediately
preceding the next scheduled Extension Date. If Executive provides the Company
notice of non-extension of the Employment Term pursuant to Section 1, Executive
shall be entitled to receive the Accrued Rights. If the Company provides
Executive notice of non-extension of the Employment Term pursuant to Section 1,
Executive shall be entitled to receive the benefits provided in Sections
8(c)(i)(A)-(C), above.

          Following such termination of Executive's employment hereunder as a
result either party's election not to extend the Employment Term, except as set
forth in this Section 8(d)(i), Executive shall have no further rights to any
compensation or any other benefits under this Agreement.

               e.   Notice of Termination. Any purported termination of
employment by the Company or by Executive (other than due to Executive's death)
shall be communicated by written Notice of Termination to the other party hereto
in accordance with Section 13(g) hereof. 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 employment under the provision so indicated.

                                                                               6

               f.   Board/Committee Resignation. Upon termination of Executive's
employment for any reason, Executive agrees to resign, as of the date of such
termination and to the extent applicable, from the Board (and any committees
thereof) and the Board of Directors (and any committees thereof) of any of the
Company's affiliates.

          9. Non-Solicitation; Non-Competition.

               a.   Executive acknowledges and recognizes the highly competitive
nature of the businesses of the Company and its affiliates and accordingly
agrees as follows:

          (1)       While Executive is employed by the Company and for six
months following the date Executive ceases to be employed by the Company (the
"Restricted Period"), Executive shall not, whether on Executive's own behalf or
on behalf of or in conjunction with any person, company, business entity or
other organization whatsoever, directly or indirectly

              (i)   solicit, or assist in soliciting, in competition with the
                    Company, the potential acquisition of refining assets in
                    the United States;

              (ii)  solicit or encourage any employee of the Company or its
                    affiliates to leave the employment of the Company or its
                    affiliates;

              (iii) hire any such person who was employed by the Company or its
                    affiliates as of the date of Executive's termination of
                    employment with the Company or whose employment with the
                    Company terminated within six months prior to the date of
                    such hire (other than any such person whose employment was
                    terminated by the Company without cause); or

              (iv)  solicit or encourage to cease to work with the Company or
                    its affiliates any consultant then under contract with the
                    Company or its affiliates.

          (2)       While Executive is employed by the Company and, following
termination of employment by the Company for Cause or by Executive without Good
Reason, for the remainder of the Employment Term (without regard to Executive's
termination of employment), Executive shall not directly or indirectly:

              (i)   engage in the business of petroleum refining or oil product
                    wholes aling in the United States

              (ii)  engage in any other business in which the Company or its
                    affiliates is engaged at the time of the termination of
                    Executive's employment, provided such other business is
                    contributing more than 10% of the Company's consolidated
                    annual revenues or net income at the time of the
                    termination of Executive's employment (any of the
                    businesses described in the preceding subparagraph (i) and
                    this subparagraph (ii) being referred to as a "Competitive
                    Business");

<PAGE>

                                                                               7

              (iii) enter the employ of, or render any services to, any entity
                    (or any division, affiliate, business unit or segment of
                    any entity) which engages in a Competitive Business;
                    provided that, notwithstanding the foregoing, it shall not
                    be a breach of Section 9(a)(2) for Executive to provide
                    services to any division, affiliate, business unit or
                    segment of any entity so long as (x) such division,
                    affiliate, business unit or segment does not itself engage
                    in a Competitive Business and (y) Executive does not,
                    directly or indirectly, provide services or advice to any
                    division, affiliate, business unit or segment of the entity
                    that does engage in a Competitive Business;

              (iv)  acquire a financial interest in (other than a passive
                    investment acquired through a hedge fund or similar
                    vehicle), or otherwise become actively involved with, any
                    Competitive Business, directly or indirectly, as an
                    individual, partner, shareholder, officer, director,
                    principal, agent, trustee or consultant; or

              (v)   interfere with, or attempt to interfere with, business
                    relationships (whether formed before, on or after the date
                    of this Agreement) between the Company or any of its
                    affiliates and their customers, clients or suppliers in
                    connection with or on behalf of a Competitive Business.

          (3)       Notwithstanding anything to the contrary in this Agreement,
Executive may, directly or indirectly own, solely as an investment, securities
of any person engaged in the business of the Company or its affiliates which are
publicly traded on a national or regional stock exchange or on the
over-the-counter market if Executive (i) is not a controlling person of, or a
member of a group which controls, such person and (ii) does not, directly or
indirectly, own 5% or more of any class of securities of such person.

               b.   It is expressly understood and agreed that although
Executive and the Company consider the restrictions contained in this Section 9
to be reasonable, if a final judicial determination is made by a court of
competent jurisdiction that the time or territory or any other restriction
contained in this Agreement is an unenforceable restriction against Executive,
the provisions of this Agreement shall not be rendered void but shall be deemed
amended to apply as to such maximum time and territory and to such maximum
extent as such court may judicially determine or indicate to be enforceable.
Alternatively, if any court of competent jurisdiction finds that any restriction
contained in this Agreement is unenforceable, and such restriction cannot be
amended so as to make it enforceable, such finding shall not affect the
enforceability of any of the other restrictions contained herein.

          10. Confidentiality. Executive agrees to hold all Company information
confidential ("Confidential Information") and shall not at any time disclose,
retain, or use such Confidential Information for Executive's own benefit or the
benefit of any other person, without the written authorization of the Board;
provided that the foregoing shall not apply to the extent that information is
required to be disclosed by law. Executive agrees that upon termination of
Executive's employment with the Company for any reason, he shall return to the
Company

<PAGE>

                                                                               8

immediately all Confidential Information and all copies thereof or therefrom,
in any way relating to the business of the Company.

          11. Specific Performance. Executive acknowledges and agrees that the
Company's remedies at law for a breach or threatened breach of any of the
provisions of Section 9 or Section 10 would be inadequate and the Company would
suffer irreparable damages as a result of such breach or threatened breach. In
recognition of this fact, Executive agrees that, in the event of such a breach
or threatened breach, in addition to any remedies at law, the Company, without
posting any bond, shall be entitled to cease making any payments or providing
any benefit otherwise required by this Agreement and obtain equitable relief in
the form of specific performance, temporary restraining order, temporary or
permanent injunction or any other equitable remedy which may then be available.

          12. Gross-Up Payment.

               a.   If it shall be determined that any amount, right or benefit
paid, distributed or treated as paid or distributed by the Company or any of its
affiliates to or for Executive's benefit (other than any amounts payable
pursuant to this Section 12) (a "Payment") would be subject to the excise tax
imposed by Section 4999 of the Internal Revenue Code of 1986 (the "Code"), or
any interest or penalties are incurred by Executive with respect to such excise
tax (such excise tax, together with any such interest and penalties,
collectively, the "Excise Tax"), then Executive shall be entitled to receive an
additional payment (a "Gross-Up Payment") in an amount equal to the amount
necessary such that after payment by Executive of all federal, state and local
taxes (including any interest or penalties imposed with respect to such taxes),
including, without limitation, any income taxes (and any interest and penalties
imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment,
Executive retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payments.

               b.   All determinations required to be made under this Section
12, including whether and when a Gross-Up Payment is required, the amount of
such Gross-Up Payment and the assumptions to be utilized in arriving at such
determination, shall be made by the Company's independent auditors (the
"Auditor"). The Auditor shall provide detailed supporting calculations to both
the Company and Executive within 15 business days of the receipt of notice from
Executive or the Company that there has been a Payment, or such earlier time as
is requested by the Company. All fees and expenses of the Auditor shall be paid
by the Company. Any Gross-Up Payment, as determined pursuant to this Section 12,
shall be paid by the Company to Executive (or to the Internal Revenue Service or
other applicable taxing authority on Executive's behalf) within 5 days of the
receipt of the Auditor's determination. All determinations made by the Auditor
shall be binding upon the Company and Executive; provided that following any
payment of a Gross-Up Payment to Executive (or to the Internal Revenue Service
or other applicable taxing authority on Executive's behalf), the Company may
require Executive to sue for a refund of all or any portion of the Excise Taxes
paid on Executive's behalf, in which event the provisions of Section 12(c) below
shall apply. As a result of uncertainty regarding the application of Section
4999 of the Code hereunder, it is possible that the Internal Revenue Service may
assert that Excise Taxes are due that were not included in the Auditor's
calculation of the Gross-Up Payments (an Underpayment"). In the event that the
Company exhausts its remedies pursuant to this Section 12 and Executive
thereafter is required to make a payment of any Excise Tax, the Auditor shall
determine the amount of the

<PAGE>

                                                                               9

Underpayment that has occurred and any additional Gross-Up Payments that are due
as a result thereof shall be promptly paid by the Company to Executive (or to
the Internal Revenue Service or other applicable taxing authority on Executive's
behalf).

               c.   Executive shall notify the Company in writing of any claim
that, if successful, would require the payment by the Company of the Gross-Up
Payment. Such notification shall be given as soon as practicable but no later
than 10 business days after Executive receives written notification of such
claim and shall apprise the Company of the nature of such claim and the date on
which such claim is requested to be paid. Executive shall not pay such claim
prior to the expiration of the 30 day period following the date on which it
gives such notice to the Company) (or such shorter period ending on the date
that any payment of taxes with respect to such claim is due). If the Company
notifies Executive in writing prior to the expiration of such period that it
desires to contest such claim, Executive shall: (i) give the Company all
information reasonably requested by the Company relating to such claim; (ii)
take such action in connection with contesting such claim as the Company shall
reasonably request in writing from time to time, including, without limitation,
accepting legal representation with respect to such claim by an attorney
reasonably selected by the Company and ceasing all efforts to contest such
claim; (iii) cooperate with the Company in good faith in order to effectively
contest such claim; and (iv) permit the Company to participate in any proceeding
relating to such claim; provided, however, that the Company shall bear and pay
directly all reasonable costs and expenses (including additional interest and
penalties) incurred in connection with such contest and shall indemnify and hold
the Executive harmless, on an after-tax basis, from any Excise Tax or income tax
(including interest and penalties with respect thereto) imposed as a result of
such representation and payment of costs and expense. Without limiting the
foregoing provisions of this Section 12, the Company shall control all
proceedings taken in connection with such contest and, at its sole option, may
pursue or forego any and all administrative appeals, proceedings, hearings and
conferences with the taxing authority in respect of such claim and may, at its
sole option, either direct Executive to pay the tax claimed and sue for a refund
or contest the claim in any permissible manner, and Executive agrees to
prosecute such contest to a determination before any administrative tribunal, in
a court of initial jurisdiction and in one or more appellate courts, as the
Company shall determine and direct; provided, however that if the Company
directs the Executive to pay such claim and sue for a refund, the Company shall
advance the amount of such payment to the Executive, on an interest-free basis,
and shall indemnify and hold the Executive harmless, on an after-tax basis, from
any Excise Tax or income tax (including interest or penalties with respect
thereto) imposed with respect to such advance or with respect to any imputed
income with respect to such advance; and further provided that any extension of
the statute of limitations relating to payment of taxes for Executive's taxable
year with respect to which such contested amount is claimed to be due is limited
solely to such contested amount. Furthermore, the Company's control of the
contest shall be limited to issues with respect to which a Gross-Up Payment
would be payable hereunder and the Executive shall be entitled to settle or
contest, as the case may be, any other issue raised by the Internal Revenue
Service or any other taxing authority.

               d.   If, after the Executive's receipt of an amount advanced by
the Company pursuant to this Section 12, the Executive becomes entitled to
receive any refund with respect to such claim, the Executive shall promptly pay
to the Company the amount of such refund (together with any interest paid or
credited thereon after taxes applicable thereto). If, after the Executive's
receipt of an amount advanced by the Company pursuant to this Section 12,

a determination is made that the Executive shall not be entitled to any refund
with respect to such claim and the Company does not notify the Executive in
writing of its intent to contest such denial of refund prior to the expiration
of 30 days after the Company's receipt of notice of such determination, then
such advance shall be forgiven and shall not be required to be repaid and the
amount of such advance shall offset, to the extent thereof, the amount of
Gross-Up Payment required to be paid.
