                               GENERAL PROVISIONS

SECTION 1.  PURPOSE OF THE PLAN

The Plan has several key objectives:

     o    Reinforce the Company's short-term and long-term business strategy

     o    Focus Company Executives on shareholder value creation

     o    Reward Company Executives for performance and provide opportunities to
          earn significant rewards for outstanding performance

     o    Enable the Company to attract, retain and motivate Company Executives

     o    Enhance teamwork

SECTION 2.  OVERVIEW OF THE PLAN

The Plan has two components - an Annual Bonus Plan and a Long-term Incentive
Plan. The Annual Bonus Plan will focus Company Executives and reinforce the
short-term business strategy by rewarding Executives for achieving short-term
operating goals. The Long-term Incentive Plan will focus Company Executives on
long-term shareholder value creation and execution of the long-term business
strategy by aligning Executives' interests with shareholders' interests.

The Plan encourages and focuses Company Executives on shareholder value
creation. Shareholder value is defined as sustained improvement in the Company's
stock price over time. The Company can create shareholder value by improving
both its short-term and long-term operating performance and growth.

Improving operating performance in the short term needs to be focused on
improving earnings while managing assets. Growing EPS while controlling the
asset base is consistent with the Company's goal of improving operating
performance relative to peers. Therefore, the best performance measures for
short-term operating performance improvement are a combination of EPS growth and
asset growth.

Improving operating performance over the long term should be captured and
measured by a single performance measure to avoid confusion. Having too many
performance measures will dilute Executives' focus on what areas of operating
performance to improve. Economic profit is the best performance measure to use
as the long-term measure for the Company because it is an all-inclusive measure
that captures both EPS growth and asset efficiency. In addition, economic profit
is highly correlated with shareholder value creation.

2000 Corporate Senior Management Incentive Plan

The Annual Bonus Plan provides for cash awards to be determined shortly after
the end of each Plan Year. The performance measures in the Annual Bonus Plan are
EPS growth and asset growth. The annual bonus Award is dependent on achieving
certain EPS and asset growth goals set at the beginning of the year by the
Compensation Committee. Each Participant is assigned threshold, target and
outstanding bonus opportunity levels.

The Long-term Incentive Plan has two components - Stock option grants and a
performance -based long-term incentive plan. The first component of the
Long-term Incentive Plan is granting a portion of the total long-term incentive
Award in stock options. Stock options are designed to align Executive's
interests with shareholders' interests by promoting growth in shareholder value.

The second component of the Long-term Incentive Plan is a performance-based
long-term incentive plan ("LTIP"). The LTIP is designed to focus corporate
Executives on improving the Company's operating performance over the long term.
The performance measure is three-year cumulative economic profit improvement.
The LTIP Award is dependent on achieving certain levels of economic profit
improvement as established at the beginning of the Performance Cycle by the
Compensation Committee. Performance Cycles are three years long and are
overlapping. The LTIP award will be a portion of Executives' total long-term
incentive award opportunity, paid in Restricted Stock (subject to the terms
provided below) based on actual economic profit improvement over the Performance
Cycle.

               growth and asset growth through their actions or decisions

               and leadership skills

          The Compensation Committee reserves the right to remove any Plan
          Participant from the Plan at any time. Plan participation in one year
          does not guarantee participation in subsequent Plan Years.

SECTION 2.  PERFORMANCE MEASURES

     (a)  Performance measures:

          The performance measures used in the Annual Bonus Plan for each
          Participant will be EPS growth and net asset growth.

     (b)  Definition of measures:

          o    EPS growth shall be defined as follows:

               -    EPS growth is the growth in EPS from the previous year to
                    the current year

<PAGE>   8

2000 Corporate Senior Management Incentive Plan

          o    Net asset growth shall be defined as follows:

               -    Net assets are consolidated total assets less non-interest
                    bearing liabilities plus securitized accounts receivable
                    plus accumulated amortization of intangible assets minus
                    cumulative translation adjustments

               -    The amount of the purchase price for any acquisitions in
                    excess of $20,000,000 will be excluded from net assets for
                    the year in which the acquisition is consummated

               -    Net assets for the Plan Year will equal the average of the
                    monthly ending net assets during the Plan Year. Similarly,
                    net assets for the prior year will equal the average of the
                    monthly ending net assets during the prior year.

               -    Net asset growth is the growth in net assets from the
                    previous year to the current year

In the determination of Awards, 75% of the weight will be assigned to EPS growth
and 25% to asset growth.

Formal and final calculations of EPS growth and asset growth will be based on
the audited financial statements of the Company as applicable.

SECTION 3.  PERFORMANCE GOALS

The Compensation Committee shall set the appropriate EPS growth and asset growth
goals for each Plan Year (subject to Section 4 of Article I) no later than 90
days into the Plan Year. The EPS growth and asset growth goals will be based on
meeting shareholder expectations as well as the Company's strategic goals. EPS
growth and asset growth goals may vary from year to year.

     (a)  Threshold goal - The minimum level of performance for which an Award
          will be earned, will be established as the threshold goal. Achieving
          the threshold goal will yield the threshold opportunity level.

     (b)  Target goal - The expected level of performance will be established as
          the target goal. Achieving the target goal will yield the target
          opportunity level.

     (c)  Outstanding goal - An outstanding level of performance, for which an
          outstanding Award will be earned, will be established as the
          outstanding goal. Achieving the outstanding goal will yield the
          outstanding opportunity level.

2000 Corporate Senior Management Incentive Plan

SECTION 4.  AWARD OPPORTUNITIES

The Compensation Committee shall set the Award opportunities for each
Participant for the Plan Year (subject to Section 4 of Article I) no later than
90 days into the Plan Year.

     (a)  Target opportunity equals a dollar amount determined by the
          Compensation Committee with respect to each Participant for each Plan
          Year.

     (b)  Threshold opportunity equals a dollar amount, which will be less than
          the target opportunity, determined by the Compensation Committee with
          respect to each Participant for each Plan Year.

     (c)  Outstanding opportunity equals a dollar amount, which will be greater
          than the target opportunity, determined by the Compensation Committee
          with respect to each Participant for each Plan Year.

Notwithstanding any other provision of this Plan to the contrary, the maximum
Award any Participant will be entitled to receive for any Plan Year under this
annual Bonus Plan is $1,500,000.

SECTION 5.  CALCULATION OF AWARDS

The Compensation Committee shall determine the Awards for each Plan Year based
on actual performance relative to the pre-established EPS growth and asset
growth goals for the year.

Actual EPS growth and asset growth performance at the target goal will result in
100% of the target opportunity.

EPS growth and/or asset growth performance between the target goal and
outstanding goal will result in a payout that is linearly interpolated between
the target and outstanding opportunities. The amount of the bonus Award shall be
capped, and therefore performance in excess of the outstanding goal will result
in the outstanding opportunity.

EPS growth and/or asset growth performance between the threshold goal and target
goal will result in a payout that is linearly interpolated between the threshold
and target opportunities. Performance that is below the threshold goal will
result in no bonus Award.

Notwithstanding the foregoing, the Compensation Committee may in its discretion
reduce the amount of any Award otherwise determined under the foregoing criteria
to reflect any extraordinary items, repurchases of Common Stock, or such other
items as it may deem relevant.

SECTION 6.  DISTRIBUTION OF AWARDS

The annual bonus Awards earned for the Plan Year will be distributed as soon as
possible after the Awards have been determined, but in no event beyond 90 days
after the end of the Plan Year. The annual bonus Award will be distributed as
cash.

SECTION 1.  ELIGIBILITY AND PARTICIPATION GUIDELINES

     (a)  Criteria for participation:

               economic profit over the long term through their actions or
               decisions

          o    Corporate executives who have demonstrated significant teamwork

          The Compensation Committee reserves the right to remove any Plan
          Participant from the Long-term Incentive Plan at any time. Plan
          participation in one Performance Cycle does not guarantee
          participation in subsequent Performance Cycles.

SECTION 2.  AWARD TYPE

The Long-term Incentive Plan has two components - Stock option grants and a
performance-based long-term incentive plan.

Granting stock options will align Executives' interests with shareholders'
interests by promoting growth in shareholder value. Accordingly, each
Participant shall be eligible to receive grants of options to purchase shares of
Common Stock.

     (a)  Such stock options shall be granted under, and subject to the terms
          of, the Stock Option and Restricted Stock Plan.

2000 Corporate Senior Management Incentive Plan

     (b)  The exercise price shall be determined by the Compensation Committee;
          provided however, that such exercise price shall not be less than 100
          percent of the Market Price (as defined in the Stock Option and
          Restricted Stock Plan) on the business day immediately preceding the
          date of grant of such stock option.

     (c)  Such stock options shall not be immediately exercisable but shall
          become exercisable as to 25 percent of the shares covered by the
          option on each of the first four anniversaries of the date of grant.

     (d)  Such stock options shall have such other terms as the Compensation
          Committee shall determine.

The second component of the Long-term Incentive Plan is the LTIP. The LTIP is
designed to focus Executives on improving the Company's operating performance
over the long term. The LTIP will have the following characteristics:

     (a)  The value of the LTIP will be a percentage of the target award
          opportunity.

     (b)  The LTIP Award is dependent on achieving three-year economic profit
          improvement goals set at the beginning of each Performance Cycle for
          the Company.

     (c)  The Award will be paid out in Restricted Stock (subject to the terms
          provided below) based on actual economic profit improvement during the
          Performance Cycle.

     (d)  The Restricted Stock shall be granted under, and subject to the terms
          of, the Stock Option and Restricted Stock Plan.

     (e)  The number of shares of Restricted Stock issued will equal the dollar
          amount of the Award divided by the Market Price (as defined in the
          Stock Option and Restricted Stock Plan) on the business day
          immediately preceding the date of grant.

     (f)  The Restricted Stock shall fully vest one year after the date of grant
          and shall be subject to such other terms as the Compensation Committee
          shall determine.

SECTION 3.  AWARD OPPORTUNITIES

The Compensation Committee shall set the Award opportunities for each
Participant for each Performance Cycle (subject to Section 4 of Article I) no
later than 90 days into the Performance Cycle.

     (a)  Target opportunity equals a dollar amount determined by the
          Compensation Committee with respect to each Participant for each
          Performance Cycle. The Stock Option Amount will equal 80% of the
          target opportunity for the

          Performance Cycle, and the LTIP Target Opportunity will equal 20% of
          the target opportunity for the Performance Cycle.

     (b)  Threshold opportunity equals a dollar amount, which will be less than
          the target opportunity, determined by the Compensation Committee with
          respect to each Participant for each Performance Cycle. The LTIP
          Threshold Opportunity will equal 20% of the threshold opportunity for
          the Performance Cycle.

     (c)  Outstanding opportunity equals a dollar amount, which will be greater
          than the target opportunity, determined by the Compensation Committee
          with respect to each Participant for each Performance Cycle. The LTIP
          Outstanding Opportunity will equal 20% of the outstanding opportunity
          for the Performance Cycle.

     (d)  Notwithstanding the foregoing, for the start-up cycles referred to in
          Section 5 of this Article, the LTIP Opportunities will be separately
          determined.

Notwithstanding any other provision of this Plan to the contrary, the maximum
Award any Participant will be entitled to receive under the LTIP component of
this Long-term Incentive Plan for any cycle (including any start-up cycle) is
$1,500,000.

SECTION 4.  PERFORMANCE MEASURES FOR LTIP

     (a)  Performance measure:

          The performance measure used in the LTIP for each Participant will be
          a three-year (except at inception as described below) cumulative
          economic profit improvement of the Company and its subsidiaries.

     (b)  Definition of measures:

          Economic profit is defined as net operating profit after taxes less a
          capital charge.

          o    Net operating profit after taxes is defined as operating profit
               plus (or minus) translation gain (loss) plus (or minus) net other
               income (loss) plus goodwill amortization plus (minus) loss (gain)
               on sale of securitized accounts receivable less taxes at the
               effective rate

          o    Capital charge is defined as net assets multiplied by cost of
               capital

               -    Net assets are consolidated total assets less non-interest
                    bearing liabilities plus securitized accounts receivable
                    plus accumulated amortization of intangible assets minus
                    cumulative translation adjustments

               -    Net assets will be calculated based on an average of the
                    monthly ending net assets during the year

                                       11
<PAGE>   14

2000 Corporate Senior Management Incentive Plan

               -    Cost of capital is the weighted average of the Company's
                    cost of equity and cost of debt as determined by the
                    Compensation Committee

     Economic profit improvement will mean the increase in economic profit for
     any year during a Performance Cycle over the economic profit, using the
     same cost of capital, in the base year.

          o    Economic profit improvement will be measured over a three-year
               period (except at inception as indicated below)

          o    The base year will be the year immediately preceding the first
               year of any Performance Cycle

          o    Any decrease in economic profit in any year during any
               Performance Cycle as compared to the base year will be subtracted
               in determining cumulative economic profit improvement for such
               cycle.

     The amount of the purchase price for any acquisitions in excess of
     $20,000,000 will be excluded from net assets for purposes of the cost of
     capital calculation, including for the base year, for the year in which the
     acquisition is consummated and for the first year thereafter

Formal and final calculations of economic profit will be based on the audited
financial statements of the Company as applicable.

SECTION 5.  PERFORMANCE GOALS FOR LTIP

For the LTIP, the Compensation Committee will set the cumulative three-year
economic profit improvement goal for each Performance Cycle (subject to Section
4 of Article I) no later than 90 days into the Performance Cycle. The economic
profit improvement goal is based on reinforcing the EPS and asset growth goals,
meeting shareholder expectations as well as Company strategic goals.

At the inception of the plan, three cycles of the LTIP will begin
simultaneously. One will be a one-year cycle (FY 2000), one is a two-year cycle
(FY 2000-2001), and one is a three-year cycle (FY 2000-2002). In subsequent
years, one three-year cycle will be instituted at the beginning of the year. The
shorter cycles will have separately determined economic profit improvement goals
reflecting the shorter periods.

     (a)  Threshold goal - The minimum level of performance for which an LTIP
          Award will be earned, will be established as the threshold goal.
          Achieving the threshold goal will yield the LTIP Threshold Opportunity
          level.

     (b)  Target goal - The expected level of performance will be established as
          the target goal. Achieving the target goal will yield the LTIP Target
          Opportunity level.

                                       12
<PAGE>   15

2000 Corporate Senior Management Incentive Plan

     (c)  Outstanding goal - An outstanding level of performance, for which an
          outstanding Award will be earned, will be established as the
          outstanding goal. Achieving the outstanding goal will yield the LTIP
          Outstanding Opportunity level.

SECTION 6.  CALCULATION OF LTIP AWARDS

The Compensation Committee shall determine the LTIP Awards for each Performance
Cycle based on actual economic profit improvement relative to the
pre-established goals for the Performance Cycle.

Actual economic profit performance at the target goal will result in 100% of the
LTIP Target Opportunity.

Economic profit performance between the target goal and outstanding goal will
result in a payout that is linearly interpolated between the LTIP Target and
LTIP Outstanding Opportunities. The LTIP Award is uncapped, and therefore
performance in excess of the outstanding goal will result in Awards based on the
linear relationship between LTIP Target and Outstanding Opportunities (subject
to the maximum specified in Section 3 of this Article III).

Economic profit performance between the threshold goal and target goal will
result in a payout that is linearly interpolated between the LTIP Threshold and
LTIP Target opportunities. Performance that is below the threshold goal will
result in no Award under the LTIP.

Notwithstanding the foregoing, the Compensation Committee may in its discretion
reduce the amount of any LTIP Award otherwise determined under the foregoing
criteria to reflect any extraordinary items or other items as it may deem
relevant.

SECTION 7.  DISTRIBUTION OF LTIP AWARDS

It is anticipated that the Restricted Stock for LTIP Awards earned for the
Performance Cycle will be granted by the Compensation Committee at the time of
the first meeting of the Compensation Committee after the end of each
Performance Cycle and the Award amounts have been determined, but in no event
later than 90 days after the end of the Performance Cycle. Any such grant shall
be subject to and shall require action by the Compensation Committee.

SECTION 8.  STOCK OPTION GRANTS

Each Participant shall be eligible to receive a grant of an option each year to
purchase shares of Common Stock on the terms specified in Section 2 of this
Article. Any such grant shall be subject to and shall require action by the
Compensation Committee (or Performance Compensation Committee as indicated
below). The number of shares for each annual grant shall be determined by the
Compensation Committee based on the following guidelines:

     (a)  The Compensation Committee shall determine the value of an option to
          purchase one share of Common Stock on the terms specified in Section 2
          using the Black-Scholes method as of the date of grant.

                                       13
<PAGE>   16

2000 Corporate Senior Management Incentive Plan

     (b)  The number of shares will equal (i) the sum of the Stock Option
          Amounts for each Performance Cycle in which the year is included
          divided by three, (ii) such amount further divided by the
          Black-Scholes value determined under subparagraph (a), above.

     (c)  Notwithstanding the foregoing, for the year 2000, the number of shares
          will equal the Stock Option Amount for the three-year Performance
          Cycle beginning in 2000, divided by the Black-Scholes value determined
          under subparagraph (a), above.

     (d)  Notwithstanding the foregoing, for the year 2001, the number of shares
          will equal (i) the sum of the Stock Option Amount for the three-year
          Performance Cycle beginning in 2000, multiplied by two and divided by
          three, and the Stock Option Amount for the three-year Performance
          Cycle beginning in 2001, divided by three, (ii) such amount further
          divided by the Black-Scholes value determined under subparagraph (a),
          above.

It is anticipated that such stock option grants will be made at the time of the
first meeting each calendar year of the Compensation Committee. A Participant
shall not be granted any such option if at the time the grant would otherwise be
made the Participant is no longer in the Employment of the Company or the Plan
has been terminated.

Notwithstanding the foregoing, in recognition of the requirements of Section
162(m) of the Code, for any Participant who is a "covered employee" under that
Section, the grant of any option to purchase Common Stock under this Plan shall
be subject to the approval of, and only made by, the Performance Compensation
Committee. However, if the Compensation Committee is comprised solely of two or
more "outside directors" under that Section at the time of the proposed grant,
such grant shall be subject to the approval of, and made by, the Compensation
Committee.

     (b)  If a Participant's Employment is terminated for any reason not
