         4. COMPENSATION AND BENEFITS.

            4.1 BASE SALARY. The Corporation shall pay to Executive a base
salary ("Base Salary") at the rate of $375,000 per annum, or such greater amount

         4.2 FIXED BONUS. The Corporation shall pay to Executive a bonus in
respect of the Corporation's fiscal year ending June 30, 2000 in an amount
determined by multiplying $200,000 times the number of days between the
Commencement Date and June 30, 2000 and dividing the result by 365, and a bonus
of $200,000 in respect of each subsequent full fiscal year during the Term,
provided that Executive remains continuously employed by the Corporation from
the Commencement Date through the end of such fiscal year. Each such bonus (a
"Fixed Bonus") shall be paid within 30 days after the end of the fiscal year in
which it is earned. Commencing with the fiscal quarter ending September 30,
2000, if requested by Executive, the Corporation shall advance to Executive, on
the last business day of each fiscal quarter, an amount equal to 12.5% of his
Fixed Bonus for the fiscal year in which such fiscal quarter ends. Such advance
shall be without interest and shall be retained by Executive and applied against
his Fixed Bonus if Executive remains employed through the end of that fiscal
year. Such advance shall bear interest at the rate of 8% per annum from the date
of the advance if Executive's employment terminates prior to the end of such
fiscal year, and shall be immediately due and payable by Executive to the
Corporation on the date of such termination. Any amounts due from Executive to
the Corporation may be offset by the Corporation against any amounts due to
Executive by the Corporation.

will establish a discretionary performance bonus program for Executive for the
Corporation's fiscal year ending June 30, 2001, and each fiscal year thereafter

Corporation's revenue and profit growth and will permit

                                       3
<PAGE>   4

Executive to earn a bonus of up to $175,000 for each fiscal year in which the
performance goals are met.

         4.4 SIGNING BONUS. Simultaneously with the execution of this Agreement,
the Corporation shall pay to Executive a signing bonus of $100,000. The net
amount of this bonus, after taxes, shall be immediately payable by Executive to
the Corporation if during the Term Executive's employment is terminated by the
Corporation for "cause" or Executive terminates his employment without "good
reason."

         4.5 INSURANCE, ETC. Executive shall be entitled to participate, to the
extent he is eligible under the terms and conditions thereof, in any pension,
retirement, disability, hospitalization, insurance, medical service, or other
employee benefit plan which is generally available to executive employees of the

his employment hereunder, including the Exec-U-Care insurance program. Without
limitation, upon commencement of his employment, Executive shall receive 401(k)

the Term. Executive shall be entitled to fly first class on the Corporation's
business.

         6. STOCK OPTIONS. On the Commencement Date, the Corporation will grant
Executive non-qualified options to purchase 250,000 shares of the Corporation's
common stock under one or more of the Corporation's existing stock option plans.
The options shall be exercisable as to 100,000 shares one year after the
Commencement Date and as to an additional 30,000 shares each year thereafter
until fully exercisable.

         7. MOVING EXPENSES. On the first business day of each of the first six
months of Executive's employment with the Corporation, the Corporation will pay
the Executive $7,500 as an advance for the purpose of covering Executive and his
family for the rental and maintenance costs of an appropriate hotel or apartment
in the greater Chicago area while Executive is relocating. Executive shall,
within thirty days following the initial six month period of employment, provide
the Corporation receipts for such costs and refund the difference, if any,
between all advances and such costs. The Corporation will also provide
reimbursement of reasonably documented moving expenses from Plano, Texas to
Chicago, up to an aggregate of $75,000, including the real estate commissions on
the sale of Executive's home in Plano, Executive's loss on his country club
membership resale and the moving of Executive's household items and two
automobiles. In addition, the Corporation will retain at its expense a
professional relocation firm to assure the purchase of Executive's home in
Plano, Texas and assist Executive in the location of a new home in the greater
Chicago area. The Corporation will reimburse Executive for the amount, if any,
by which the purchase price paid by Executive for Executive's home in Plano
exceeds the sale price obtained upon the sale of Executive's home in Plano,
Texas to prevent Executive from suffering a loss between the price he paid for
the Plano home and the sales price for the Plano home. Executive

                                       5
<PAGE>   6

shall provide the Corporation with documentation showing the purchase price he
paid for his home in Plano. Executive will be responsible for the taxes, if any,
payable by Executive by reason of any reimbursement or payments made by the
Corporation pursuant to this Paragraph 7.

         8. VACATION. Executive shall be entitled to four weeks paid vacation
per year. Any such vacations are to be taken at times mutually agreeable to
Executive and the Chief Executive Officer of the Corporation. Vacation time
shall not be accumulated from year to year, unless Executive is requested by the
Chief Executive Officer of the Corporation to forego a vacation.

         9. KEY-MAN LIFE INSURANCE. The Corporation may purchase and maintain
life insurance covering the life of Executive ("Key-man Insurance") in an amount
determined by the Corporation. The Corporation shall be the sole owner and
beneficiary of the Key-man Insurance and may apply to the payment of premiums
thereunder any dividends declared and paid thereon. Executive shall submit
himself to such physical examinations as the Chief Executive Officer of the
Corporation may deem necessary or desirable in connection with the purchase and
maintenance of the Key-man Insurance.

         10. NON-COMPETITION AND NON-RAIDING. In consideration of the

            10.1 NON-COMPETITION. Executive agrees that during a period from the
Commencement Date until one year after the termination of Executives employment
hereunder for any reason, he will not, directly or indirectly, without the prior
written consent of the Corporation, own, manage, operate, join, control,
participate in, perform any services for, invest in, or otherwise be connected
with, in any manner, whether as an officer, director, employee, consultant,

investor or otherwise, any business entity which is engaged in the design,
importation, manufacture and/or sale of electronic gaming devices or
coin-operated amusement games or any business entity which is engaged in any
other business in which the Corporation or any affiliate of the Corporation is
engaged at the end of the Term or the time of termination of Executive's
employment or, to the knowledge of Executive, is planning to be engaged within
one year after such termination. Nothing herein contained shall be deemed to (i)
prohibit Executive from investing his funds in securities of a company if the
securities of such company are listed for trading on a national stock exchange
or traded in the over-the-counter market and Executive's holdings therein
represent less than five percent of the total number of shares or principal
amount of other securities of such company outstanding, or (ii) prohibit or
limit the right of Executive to return to the hotel/casino business as an
operator and/or owner.

            10.2 NON-RAIDING. Executive agrees that during a period from the
Commencement Date until two years after the termination of employment hereunder
for any reason, he will not, directly or indirectly, without the prior written
consent of the Corporation, induce or influence, or seek to induce or influence,
any person who is engaged by the Corporation or any affiliate of the Corporation
as an employee, agent, independent contractor or otherwise, to terminate his
employment or engagement, nor shall Executive directly or indirectly, through
any other person, firm or corporation, employ or engage, or solicit for
employment or engagement, or advise or recommend to any other person or entity
that such person or entity employ or engage or solicit for employment or
engagement, any person or entity employed or engaged by the Corporation or any
affiliate of the Corporation.

            10.3 MODIFICATION. Executive acknowledges that the provisions of
this Paragraph 10 are reasonable and necessary for the protection of the
Corporation. In the event that any provision of this Paragraph 10, including any
sentence, clause or part hereof, shall be deemed contrary to law or invalid or
unenforceable in any respect by a court of competent jurisdiction, the remaining
provisions shall not be affected, but shall, subject to the discretion of such
court, remain in full force and effect and any invalid and unenforceable
provisions shall be deemed, without further action on the part of the parties
hereto, modified, amended and limited to the extent necessary to render the same
valid and enforceable.

         11. CONFIDENTIALITY AGREEMENT.

         11.1 As used herein, the term "Confidential Information" shall mean any
and all information of the Corporation and of its affiliates (for purposes of
this paragraph, the Corporation's affiliates shall be deemed included within the
meaning of "Corporation"), including, but not limited to, all data,
compilations, programs, devices, strategies, or methods concerning or related to
(i) the Corporation's finances, financial condition, results of operations,
employee relations, amounts of compensation paid to officers and employees and
any other data or information relating to the internal affairs of the
Corporation and its operations; (ii) the terms and conditions (including prices)
of sales and offers of sales of the Corporation's products and services; (iii)
the terms, conditions and current status of the Corporation's agreements and
relationship with any customer or supplier; (iv) the customer and supplier lists
and the identities and business preferences of the Corporation's actual and
prospective customers and suppliers or any employee or agent thereof with whom
the Corporation communicates; (v) the trade secrets, manufacturing and operating
techniques, price data,

                                       8
<PAGE>   9

costs, methods, systems, plans, procedures, formulas, processes, hardware,
software, machines, inventions, designs, drawings, artwork, blueprints,
specifications, tools, skills, ideas, and strategic plans possessed, developed,
accumulated or acquired by the Corporation; (vi) any communications between the
Corporation, its officers, directors, stockholders, or employees, and any
attorney retained by the Corporation for any purpose, or any person retained or
employed by such attorney for the purpose of assisting such attorney in his or
her representation of the Corporation; (vii) any other information and knowledge
with respect to all products developed or in any stage of development by the
Corporation; (viii) the abilities and specialized training or experience of
others who as employees or consultants of the Corporation during the Term have
engaged in the design or development of any such products; and (ix) any other
matter or thing, whether or not recorded on any medium, (a) by which the
Corporation derives actual or potential economic value from such matter or thing
being not generally known to other persons or entities who might obtain economic
value from its disclosure or use, or (b) which gives the Corporation an
opportunity to obtain an advantage over its competitors who do not know or use
the same.

         11.2 Executive acknowledges and agrees that the Corporation is engaged
in highly competitive businesses and has expended, or will expend, significant
sums of money and has invested, or will invest, a substantial amount of time to
develop and maintain the secrecy of the Confidential Information. The
Corporation has thus obtained, or will obtain, a valuable economic asset which
has enabled, or will enable, it to develop an extensive reputation and to
establish long-term business relationships with its suppliers and customers. If
such Confidential Information were disclosed to another person or entity or used
for the benefit of anyone other than the Corporation,

                                        9
<PAGE>   10

the Corporation would suffer irreparable harm, loss and damage. Accordingly,
Executive acknowledges and agrees that, unless the Confidential Information
becomes publicly known through legitimate origins not involving an act or
omission by Executive:

         (1)   the Confidential Information is, and all times hereafter shall
               remain, the sole property of the Corporation;

         (2)   Executive shall use his best efforts and the utmost diligence to
               guard and protect the Confidential Information from disclosure to
               any competitor, customer or supplier of the Corporation or any
               other person, firm, corporation or other entity;

         (3)   unless the Corporation gives Executive prior express written
               permission, during his employment and thereafter, Executive shall
               not use for his own benefit, or divulge to any competitor or
               customer or any other person, firm, corporation, or other entity,
               any of the Confidential Information which Executive may obtain,
               learn about, develop or be entrusted with as a result of
               Executive's employment by the Corporation; and

         (4)   except in the ordinary course of the Corporation's business,
               Executive shall not seek or accept any Confidential Information
               from any former, present or future employee of the Corporation.

         11.3 Executive also acknowledges and agrees that all documentary and
tangible Confidential Information including, without limitation, such
Confidential Information as Executive

                                       10
<PAGE>   11

has committed to memory, is supplied or made available by the Corporation to the
Executive solely to assist him in performing his services under this Agreement.
Executive further agrees that after his employment with the Corporation is
terminated for any reason:

         (1)   Executive shall not remove from the property of the Corporation
               and shall immediately return to the Corporation, all documentary
               or tangible Confidential Information is his possession, custody,
               or control and not make or keep any copies, notes, abstracts,
               summaries, tapes or other record of any type of Confidential
               Information; and

         (2)   Executive shall immediately return to the Corporation any and all
               other property of the Corporation in his possession, custody or
               control, including, without limitation, any and all keys,
               security cards, passes, credit cards and marketing literature.

         12. INVENTION DISCLOSURE. Any invention, improvement, design,
development or discovery conceived, developed, created or made by Executive
alone or with others, during the period of his employment hereunder and
applicable to the business of the Corporation or its affiliates, whether or not
patentable or registrable, shall become the sole and exclusive property of the
Corporation. Executive hereby assigns to the Corporation, all of his rights to
any "intellectual material" created or developed by him during the course of his
employment. As used herein, "intellectual material" shall include, but shall not
be limited to, ideas, titles, themes, production ideas, methods of presentation,
artistic renderings, sketches, plots, music, lyrics, dialogue, phrases,

                                       11
<PAGE>   12

slogans, catch words, characters, names and similar literary, dramatic and
musical material, trade names, trademarks and service marks and all
copyrightable expressions in audio visual works, computer software, electronic
circuitry and all mask works for integrated circuits. Executive shall disclose
the intellectual material promptly and completely to the Corporation and shall,
during the period of his employment hereunder and at any time and from time to
time hereafter (a) execute all documents requested by the Corporation for
vesting in the Corporation or any of its affiliates the entire, right, title and
interest in and to the same, (b) execute all documents requested by the
Corporation for filing and prosecuting such applications for patents, trademarks
and/or copyrights as the Corporation, in its sole discretion, may desire to
prosecute, and (c) give the Corporation all assistance it reasonably requires,
including the giving of testimony in any suit, action or proceeding, in order to
obtain, maintain and protect the Corporation's right therein and thereto. If any
such assistance is required following the termination of this Agreement, the
Corporation shall reimburse Executive for his time and the reasonable expenses
incurred by him in rendering such assistance. Anything contained in this
paragraph to the contrary notwithstanding, this paragraph does not apply to an
invention for which no equipment, supplies, facilities, or trade secret
information of the Corporation or its affiliates was used and which was
developed entirely on the Executive's own time, unless (d) the invention
relates: (i) to the business of the Corporation or its affiliates, or (ii) to
the Corporation's or any of its affiliates' actual or demonstrably anticipated
research or development, or (e) the invention results from any work performed by
the Executive for the Corporation or its affiliates.

                                       12
<PAGE>   13

         13. REMEDIES. Executive acknowledges and agrees that the business of
the Corporation is highly competitive and that violation of any of the covenants
provided for in Paragraphs 10, 11 and 12 of this Agreement would cause
immediate, immeasurable and irreparable harm, loss and damage to the Corporation
not adequately compensable by a monetary award. Accordingly, Executive agrees,
without limiting any of the other remedies available to the Corporation, that
any violation of said covenants, or any one of them, may be enjoined or
restrained by any court of competent jurisdiction, and that any temporary
restraining order or emergency, preliminary or final injunctions may be issued
by any court of competent jurisdiction, without notice and without bond. In the
event any proceedings are commenced by the Corporation against Executive for any
actual or threatened violation of any of said covenants and if the Corporation
prevails in such litigation, then, Executive shall be liable to the Corporation
for, and shall pay to the Corporation, all costs and expenses of any kind,
including reasonable attorneys' fees, which the Corporation may incur in
connection with such proceedings.

         14. TERMINATION OF EMPLOYMENT.

            14.1 DEATH. Executive's employment shall terminate automatically
upon the death of Executive.

            14.2 DISABILITY. If the Corporation determines in good faith that
the disability of Executive has occurred during the term hereof (pursuant to the
definition of "disability" set forth below), it may give to Executive written
notice in accordance with Paragraph 17 of this Agreement of its intention to
terminate Executive's employment. In such event, Executive's employment with the
Corporation shall terminate effective on the 30th day after receipt of such
notice by Executive (the

                                       13
<PAGE>   14

"Disability Effective Date"), provided that, within the 30 days after such
receipt, Executive shall not have returned to full-time performance of
Executive's duties. For purposes of this Agreement, "disability" shall mean the
absence of Executive from Executive's duties with the Corporation on a full-time
basis for 60 consecutive business days as a result of incapacity due to mental
or physical illness which is determined to be total and permanent by a physician
selected by the Corporation or its insurers and acceptable to Executive or
Executive's legal representative.

            14.3 CAUSE. The Corporation may terminate Executive's employment
during the term hereof for "cause." For purposes of this Agreement, "cause"
means (i) conviction of a felony or any other crime involving fraud, larceny or
dishonesty; (ii) failure and refusal to follow a reasonable direction of the
Chief Executive Officer or the Board of Directors of the Corporation after
notice in writing of such failure or refusal and a cure period of ten days
thereafter; (iii) commission of any dishonest, willful or grossly negligent act
which has or is reasonably likely to have a material adverse effect on the
Corporation or its customer or trade relationships; or (iv) failure or refusal
to provide accurate and reasonably complete information with respect to
Executive's personal history to the Corporation or to governmental agencies
regulating the business of the Corporation, failure or refusal to reasonably
cooperate with such regulators or failure to obtain necessary regulatory
licensing approvals or clearances because of inaccurate, incomplete or falsified
information provided by Executive. It is understood that poor financial
performance of the Corporation shall not in itself constitute grounds for the
termination of Executive for "cause."

            14.4 GOOD REASON. Executive's employment may be terminated by
Executive for "good reason." For purposes of this Agreement, "good reason" shall
mean a material breach by the

                                       14
<PAGE>   15

Corporation of any material provision of this Agreement, after the Executive has
provided the Corporation with notice thereof and a reasonable opportunity to
cure such breach.

            14.5 NOTICE OF TERMINATION. Any termination by the Corporation for
"cause", or by Executive for "good reason", shall be communicated by Notice of
Termination to the other party hereto given in accordance with Paragraph 17 of
this Agreement. For purposes of this Agreement, a "Notice of Termination" means
a written notice which (i) indicates the specific termination provision in this
Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
Executive's employment under the provision so indicated and (iii) if the Date of
Termination (as defined below) is other than the date of receipt of such notice,
specifies the termination date (which date shall be not more than thirty days
after the giving of such notice). The failure by Executive or the Corporation to
set forth in the Notice of Termination any fact or circumstance which
contributes to a showing of "good reason" or "cause" shall not waive any right
of Executive or the Corporation, respectively, hereunder or preclude Executive
or the Corporation, respectively, from asserting such fact or circumstance in
enforcing Executive's or the Corporation's rights hereunder.

            14.6 DATE OF TERMINATION. "Date of Termination" means (i) if
Executive's employment is terminated by the Corporation for "cause", or by
Executive for "good reason", the date of receipt of the Notice of Termination or
any later date specified therein, as the case may be, (ii) if Executive's
employment is terminated by the Corporation other than for "cause" or
"disability", the Date of Termination shall be the date on which the Corporation
notifies Executive of such termination and (iii) if Executive's employment is
terminated by reason of death or

                                       15
<PAGE>   16

"disability", the Date of Termination shall be the date of death of Executive or
the Disability Effective Date, as the case may be.

            14.7 PAYMENTS AS A RESULT OF TERMINATION. (1) If, during the Term,
the Corporation shall terminate Executive's employment other than for "cause",
including by reason of the Executive's death or "disability", or Executive shall
terminate employment for "good reason:"

            (1) the Corporation shall pay to Executive in a lump sum in cash
                within 30 days after the Date of Termination the aggregate of
                the amounts set forth in clauses A and B below:

                1. the sum of (1) Executive's annual Base Salary through the
            Date of Termination to the extent not theretofore paid, and (2) the
            product of (x) the annual Fixed Bonus and (y) a fraction (the
            "Proration Fraction"), the numerator of which is the number of days
            in the current fiscal year through the Date of Termination, and the
            denominator of which is 365, less any advances theretofore made to
            Executive in respect of the annual Fixed Bonus (the sum of the
            amounts described in clauses (1) and (2) shall be hereinafter
            referred to as the "Accrued Obligations"); and

                2. (x) if the termination is by reason of Executive's death or
            "disability", the amount equal to one year's Base Salary and one
            year's Fixed Bonus; or (y) if the termination is other than for
            "cause", death or "disability", or Executive shall terminate for
            "good reason", the amount equal to the greater of (i) one year's
            Base Salary and one year's Fixed Bonus, or (ii) the product of (1)
            the number of

                                       16
<PAGE>   17

            years (including fractions thereof) remaining from the Date of
            Termination until the end of the Term and (2) the sum of one year's
            Base Salary and one year's Fixed Bonus.

             (2) If the Executive's employment shall be terminated for "cause"
or the Executive terminates employment without "good reason" during the Term,
this Agreement shall terminate without further obligations to Executive other
than the obligation to pay to Executive the Accrued Obligations, provided,
however, if Executive terminates employment without good reason prior to one
year from the Commencement Date, in addition to the Accrued Obligations the
Corporation shall pay to Executive the amount equal to one year's Base Salary
and Fixed Bonus payable in 12 equal monthly installments beginning one month
after the Date of Termination, which payment will be reduced by any amounts
received by Executive from other employment during such payment period.

         15. CHANGE OF CONTROL.

            15.1 If at any time during the Term, individuals who presently
constitute the Board of Directors of the Corporation, or who have been
recommended for election to the Board by two-thirds of the Board consisting of
individuals who are either presently on the Board or such recommended successors
cease for any reason to constitute at least a majority of such Board (such event
being hereafter referred to as a "Change of Control") and Executive gives
written notice to the Corporation within 60 days after such Change of Control of
his election to terminate his employment hereunder, the Corporation shall pay to
Executive within 15 days after Executive's delivery of such notice, as severance
pay and liquidated damages, in lieu of any other rights or remedies which might

                                       17
<PAGE>   18

otherwise be available to him under his Agreement, and without mitigation of any
kind or amount, whether or not Executive shall seek or accept other employment,
a lump sum payment equal in amount three times the annual Base Salary and annual
Fixed Bonus payable to Executive pursuant to Sections 4.1 and 4.2 of this
Agreement. In addition, all unexpired options to purchase securities of the
Corporation granted to Executive before the Change of Control shall, if
unvested, vest fully on the date of the Change of Control, notwithstanding any
vesting provisions of such options. The payments provided for in this Section 15
shall be paid in full, without discount to present value.

            15.2 If it shall be determined that any amount payable under Section
15.1 by the Corporation to or for the benefit of Executive (a "Base Payment")
would be subject to the excise tax (the "Excise Tax") imposed by Section 4999 of
the Internal Revenue Code of 1986, as amended (the "Code"), then Executive shall
be entitled to receive an additional payment (the "Gross-Up Payment") in an
amount such that the net amount retained by Executive, after the calculation and
deduction of any Excise Tax on the Base Payment shall be equal to the Base
Payment, less any federal, state and local income taxes. The Gross-Up Payment
shall be reduced by income or Excise Tax withholding payments made by the
Corporation to any federal, state, or local taxing authority with respect to the
Gross-Up Payment that was not deducted from compensation payable to the
Executive. All determinations required to be made under this Section 15.2,
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, except as specified above, shall be made by the Corporation's
auditors (the "Accounting Firm"), which shall provide detailed supporting
calculations both to the Corporation and Executive within fifteen business days
after the receipt of notice from

                                       18
<PAGE>   19

Executive that there should be a Gross-Up Payment. The determination of tax
liability made by the Accounting Firm shall be subject to review by Executive's
tax advisor, and, if Executive's tax advisor does not agree with the
determination reached by the Accounting Firm, then the Accounting Firm and
Executive's tax advisor shall jointly designate a nationally recognized public
accounting firm, which shall make the determination. All fees and expenses of
the accountants retained by the Corporation or jointly designated and retained
shall be borne by the Corporation. Any determination by a jointly designated
public accounting firm shall be binding upon the Corporation and Executive.

            16. ENTIRE AGREEMENT. This Agreement constitutes the entire
agreement of the parties hereto with respect to Executive's employment with the
Corporation and no amendment or modification hereof shall be valid or binding
unless made in writing and signed by the party against whom enforcement thereof
is sought.

            17. NOTICES. Any notice required, permitted or desired to be given
pursuant to any of the provisions of this Agreement shall be deemed to have been

                              AMENDMENT NUMBER ONE
                             TO EMPLOYMENT AGREEMENT
                             DATED DECEMBER 15, 1999

         THIS IS AMENDMENT NUMBER ONE to the Employment Agreement entered into
between Yellow Corporation, a Delaware Corporation ('"Yellow") and William D.
Zollars (the "Executive") on the 15th day of December, 1999.

         1.  Paragraph 4(d) of said Employment Agreement is hereby amended in
             its entirety to read as follows:

             (d)  Supplemental Retirement Benefits. Yellow shall provide
                  Executive with Supplemental Retirement Benefits in accordance
                  with this subsection (d) and Appendix A pursuant to which the
                  Executive shall receive from Yellow upon his termination of
                  employment with Yellow (and subject to the vesting provision
                  hereinafter set forth), the difference between (i) the monthly
                  benefit that he would have received under Section 4.4 of the
                  Yellow Freight Office, Clerical, Sales and Supervisory
                  Personnel Pension Plan (the "Pension Plan") (calculated as a
                  single life annuity payable commencing at his initial Normal
                  Retirement Date as defined under the Pension Plan with an
                  actuarial reduction if payment commences prior to his Normal
                  Retirement Date) using 20 years of Credit Service as defined
                  in the Pension Plan plus his actual Credit Service credited
                  under the Pension Plan after five (5) years from September 6,
                  1996, the date of Executive's commencement

                                       1
<PAGE>   2

                  of employment with Yellow's subsidiary, Yellow Freight System,
                  Inc., and using compensation as defined in Section 2.1(h)2 of
                  the Pension Plan, including Compensation previously earned
                  during his employment with Yellow Freight System, Inc. from
                  September 6, 1996 through November 7, 1999, but without any
                  reduction under Section 401(a)(17) of the Internal Revenue
                  Code of 1986, as amended (the "Code") and (ii) the monthly
                  benefit actually payable to the Executive under Section 4.4 of
                  the Pension Plan, calculated at the time the Executive
                  commences payment of a Vested Pension under the Pension Plan,
                  if any. The Executive shall vest in the Supplemental
                  Retirement Benefit described in this subsection (d) at the
                  rate of 20% per year commencing on September 6, 1997 (so that
                  he would become 100% vested on September 6, 2001), provided,
                  however, that the Executive shall forfeit any unvested portion
                  in the event of the termination of his employment prior to
                  becoming 100% vested. Notwithstanding the foregoing, the
                  Executive shall immediately become 100% vested in the event of
                  the termination of his employment under circumstances
                  entitling the Executive to benefits pursuant to Section 8.
                  Following the termination of Executive's employment, the
                  Supplemental Retirement Benefit described in this subsection
                  (d) and Appendix A shall be payable monthly commencing no
                  sooner than the earliest date of Executive's eligibility to
                  receive Retirement Benefits under the Pension Plan measured
                  from his

                                       2
<PAGE>   3

                  date of termination with Executive having the option of
                  deciding when to commence payments following achieving such
                  eligibility, subject to actuarial reduction for payments
                  commencing prior to Executive's Normal Retirement Date, and
                  shall continue until the Executive's death. Upon the
                  Executive's death, if at the time of his death payments had
                  already commenced under the Supplemental Retirement Benefit
                  and if he is survived by and still married to the person who
                  was his spouse on September 6, 1996, the monthly Supplemental
                  Retirement Benefit payable to the Executive during his life
                  shall continue to said surviving spouse until her death. If at
                  the time of his death, the Executive had not yet qualified for
                  payment of a Retirement Benefit under the Pension Plan, or if
                  Executive had qualified but payments had not yet commenced, if
                  he is survived by and still married to the person who was his
                  spouse on September 6, 1996, the Supplemental Retirement
                  Benefit shall be payable to said spouse no sooner than the
                  earliest date that Executive would have been eligible to
                  receive Retirement Benefits under the Pension Plan measured
                  from his date of death with said spouse having the option of
                  deciding when to commence payments following the date that
                  Executive would have achieved such eligibility, subject to
                  actuarial reduction for payments commencing prior to the date
                  that Executive would have reached his Normal Retirement Date,
                  and shall continue to said surviving spouse until her death.

                  The Executive acknowledges that these Supplemental Retirement
                  Benefits are an element of the compensation to be paid for his
                  services and not an unfunded plan of deferred compensation
                  within the meaning of Section 201 of the Employee Retirement
                  Income Security Act, as amended.

         2.  All other provisions and conditions of the Employment Agreement
             dated December 15, 1999 remain in full force and effect.

         IN WITNESS WHEREOF, the parties have executed this Amendment Number One
to the Agreement dated December 15, 1999 on the 20th day of April, 2000.

THE EXECUTIVE:                                    YELLOW CORPORATION
