agreements that shall be executed on behalf of the Sponsor and by the respective
Optionees, containing terms determined from time to time by the Committee,

years from the date of adoption of the Plan by the Board.

Option shall be the Fair Market Value of a Share on the Date of Grant.

transferable otherwise than by will or the laws of descent and distribution and,
during the lifetime of the Optionee, shall be exercisable only by him or her, or

death of an Optionee, the person to whom the Option has been transferred may
exercise any Options only in accordance with the provisions of Paragraph 7(f).

                                       4
<PAGE>   5

         (d)      PAYMENT UPON EXERCISE OF OPTIONS. Full payment for Shares
purchased upon the exercise of an Option shall be made in cash or, at the
election of the Optionee and as the Committee may, in its sole discretion,
approve, by surrendering Shares held for six months or more on the date of
exercise with an aggregate Fair Market Value equal to the aggregate option
price, or by delivering such combination of Shares and cash as the Committee
may, in its sole discretion, approve.

         (e)      ISSUANCE OF CERTIFICATE UPON EXERCISE OF OPTIONS. Whole Shares
shall be issuable upon exercise of Options. Upon satisfaction of the conditions
of Paragraph 7(g), a certificate for the number of Shares to which the Optionee
is entitled shall be delivered to such Optionee by the Sponsor. Cash shall be
paid in lieu of fractional Shares.

         (f)      PERIODS OF EXERCISE OF OPTIONS. An Option shall be exercisable
in whole or in part at such time or times as may be determined by the Committee
and stated in the Option Agreement; PROVIDED, HOWEVER, that except as otherwise
provided by the Committee in its discretion, no Option or part thereof shall
first become exercisable following an Optionee's termination of employment for
any reason;

                  (i)      Provided further, that:

                           (w) Except as otherwise provided in Paragraph
                  7(f)(i)(z), in the event of termination of an Optionee's
                  employment with the Primark Companies for any reason other
                  than death, disability retirement, or for "cause," any Option
                  held by such Optionee and which is then exercisable shall be
                  exercisable for a period of three months following the date
                  the Optionee terminates employment with the Primark Companies
                  (unless a longer period is established by the Committee);
                  PROVIDED, HOWEVER, that in no event shall an Option be
                  exercisable after ten years from the Date of Grant.

                           (x) Except as otherwise provided in Paragraph
                  7(f)(i)(z), in the event that an Optionee terminates
                  employment with the Primark Companies by reason of death,
                  disability or retirement, any Option held at death or
                  retirement by such Optionee which is then exercisable shall be
                  exercisable for a period of one year from the date of death
                  disability or retirement (unless a longer period is
                  established by the Committee) by the Optionee (or in the case
                  of death, by the person to whom the rights of the Optionee
                  shall have passed by will or by the laws of descent and
                  distribution); PROVIDED, HOWEVER, except as otherwise provided
                  in Paragraph 7(f)(i)(z), in no event shall an Option be
                  exercisable after ten years from the Date of Grant.

                           (y) In the event that an Optionee's employment with
                  the Primark Companies terminates for "cause" (as defined by
                  the Committee, or, if the Optionee is a party to an employment
                  agreement with the employing Primark Company that provides for
                  a definition of the term "cause," "cause" as so defined), any
                  unexercised Option shall terminate on the date of termination
                  of employment.

                                       5
<PAGE>   6

                           (z) No Option shall be exercisable if the issuance of
                  Shares pursuant to the exercise of such Option would violate
                  the provisions of any loan agreement to which the Sponsor or
                  any Subsidiary Company is a party, provided that if no
                  violation of such loan agreement would occur if the Optionee
                  were to pledge the Shares issuable pursuant to the exercise of
                  such Option in accordance with a pledge and security agreement
                  in a form acceptable under such loan agreement and reasonably
                  satisfactory to the Sponsor and the Optionee, the Optionee may
                  elect to exercise such Option and pledge the Shares issuable
                  pursuant to the exercise of such Option accordingly. If, as of
                  the date an Option would otherwise cease to be exercisable
                  under Paragraphs 7(f)(i)(w), 7(f)(i)(x) and 7(f)(i)(y) because
                  of the passage of time, an Option is not exercisable solely
                  because the exercise of such Option would violate the
                  provisions of any loan agreement to which the Sponsor or any
                  Subsidiary Company is a party (whether or not the Optionee
                  were to pledge the Shares issuable pursuant to the exercise of
                  such Option), the periods during which such Option may be
                  exercised under Paragraphs 7(f)(i)(x) and 7(f)(i)(y) shall be
                  extended to the close of the 30-day period beginning on the
                  date on which the exercise of such Option would not violate
                  the provisions of any loan agreement to which the Sponsor or
                  any Subsidiary Company is a party, provided however that in no
                  event shall any Option be exercisable after ten years from the
                  Date of Grant.

                  (ii) For purposes of this Paragraph 7(f), an Optionee's
                  termination of employment shall be deemed to occur on the date
                  of termination of employment as determined in accordance with
                  the Optionee's employer's standard personnel policies or, if
                  the Optionee is a party to an employment agreement with a
                  Primark Company, the date of termination of employment for
                  purposes of the Plan shall be as determined under such
                  agreement, or on the date the Optionee's service as a director
                  terminates for any reason, or on the date the Optionee's
                  service pursuant to his or her engagement as a consultant or
                  advisor terminates for any reason, as applicable.

         (g)      MANNER AND DATE OF EXERCISE. The Optionee shall exercise the
Option by delivering to the Company at the address specified below the
following: (a) written notice that specifies the Option being exercised, the
number of Shares being acquired, and the manner of payment; (b) payment in full
of the Option Price for such Shares and all applicable withholding taxes as
stated in Paragraph 14; and (c) a fully executed Stockholder's Agreement. In
case these separate conditions are fulfilled on different dates, the Date of
Exercise shall be the date on which all the conditions to exercise are
fulfilled. Exercise shall be irrevocable once all the conditions are fulfilled.

         (h)      TERMINATION OF EMPLOYMENT. For purposes of the Plan, a
transfer of service between two employers, each of which is a Primark Company,
or a change of relationship to a Primark Company from "employee" to
"consultant," shall not be deemed a termination of employment.

                                       6

8.    RIGHTS AS STOCKHOLDERS

         An Optionee shall not have any right as a stockholder with respect to
any Shares subject to his or her Option until all the conditions in Paragraph
7(g) hereof and the Option Agreement shall have been fulfilled.

9.    CHANGES IN CAPITALIZATION; ANTI-DILUTION PROVISIONS

         The Board of Directors of the Company shall make appropriate
adjustments to the number and class of shares of Common Stock available for
issuance under the Plan, and/or to the number, class and Option Price of
outstanding Options in the event that:

         (a)      Shares are changed into or exchanged for a different number or
kind of shares of stock or other securities of the Sponsor, whether through
merger, consolidation, reorganization, recapitalization, reclassification, stock
dividend, stock split-up, issuance of warrants, rights, or options (other than
pursuant to the Plan) or change in corporate structure or otherwise; or

         (b)      A Public Offering has not previously been consummated when
Common Stock (or any security convertible into Common Stock) shall be issued
(other than upon the exercise of Options issued under the Plan) at a price or
for consideration less than the Fair Market Value at the time the Shares are
issued.

Any reference to the Option Price in the Plan and Option Agreements shall be a
reference to the Option Price as so adjusted. Any reference to the term "Shares"
in the Plan and Option Agreements shall be a reference to the appropriate number
and class of shares of Common Stock available for issuance under the Plan, as
adjusted pursuant to this Paragraph 9. The Committee's adjustment shall be
effective and binding for all purposes of this Plan. The adjustment provided for
in this Paragraph 9 may require the Sponsor to issue fractional shares, and the
total adjustment with respect to the Plan shall be determined accordingly.

10.   TERMINATING EVENTS

         (a)      IN GENERAL. The Sponsor shall give Optionees at least fifteen
(15) days' notice (or, if not practicable, such shorter notice as may be
reasonably practicable) prior to the anticipated date of the consummation of a
Terminating Event other than a Primark Change of Control. Upon receipt of such
notice, and continuing to the date of consummation of the Terminating Event (or
such earlier date as the Board shall reasonably determine in its discretion and
set forth in such notice), each Optionee shall be permitted to exercise all
Options then held by such Optionee, whether or not then otherwise vested,
PROVIDED THAT, in the event of a Terminating Event in which the Optionee would
be required to participate pursuant to Section 2.7 of the Stockholder's
Agreement were the Optionee then a party to such agreement, the Sponsor may, by
similar notice, require the Optionee to exercise the Option, to the extent the
Option is then exercisable, or to forfeit the Option (or portion thereof, as
applicable). Upon the close of the period described in this Paragraph 10(a)
during which an Option may be exercised in connection with a Terminating Event,
such Option (including such portion thereof that is not exercisable) shall
terminate.

                                       7
<PAGE>   8

         (b)      PRIMARK CHANGE OF CONTROL. The Sponsor shall give Optionees at
least fifteen (15) days' notice (or, if not practicable, such shorter notice as
may be reasonably practicable) prior to the anticipated date of the consummation
of a Primark Change of Control. Upon receipt of such notice, and continuing to
the date of consummation of the Primark Change of Control (or such earlier date
as the Board shall reasonably determine in its discretion and so notify the
Optionees), each Optionee shall be permitted to exercise the Option for all
Options then held by such Optionee, whether or not then otherwise exercisable.
Upon the close of the period described in this Paragraph 10(b) during which an
Option may be exercised in connection with a Terminating Event, such Option
(including such portion thereof that is not exercisable) shall terminate.

         (c)      IF THE TERMINATING EVENT IS NOT CONSUMMATED. Notwithstanding
Paragraphs 10(a) and 10(b), in the event the Terminating Event is not
consummated, the Option shall be deemed not to have been exercised, any notice
of exercise shall be void, any consideration delivered to the Sponsor shall be
returned to the Optionee, and any certificate for Shares that may have been
issued shall be returned to the Sponsor, and the Option shall be exercisable
thereafter to the extent it would have been exercisable if no such notice had
been given. Notwithstanding the above, to the extent any Option exercised
pursuant to Paragraph (a) or (b) would have been exercisable without the notice
of a Terminating Event, the Optionee may elect to treat the exercise as valid,
with respect to any vested portion of the Option.

11.   INTERPRETATION

         The Committee shall have the power to interpret the Plan and to make
and amend rules for putting it into effect and administering it. It is intended
that Options shall be Non-Qualified Options, and that Shares transferred
pursuant to their exercise shall constitute property subject to federal income
tax pursuant to the provisions of section 83 of the Code, and that Options not
be treated as "incentive stock options" described in section 422 of the Code.
The provisions of the Plan shall be interpreted and applied insofar as possible
to carry out such intent.

12.   AMENDMENTS:

         The Plan may be amended by the Board, provided that no outstanding
Option shall be adversely affected by any such amendment without the written
consent of the Optionee or other person then entitled to exercise such Option.

13.   SECURITIES LAW

         The Committee shall have the power to make each grant under the Plan
subject to such conditions as it deems necessary or appropriate to comply with
the then-existing requirements of law, including the Securities Act of 1933, as
amended, or the Securities Exchange Act of 1934, as amended, including Rule
16b-3 (or any similar rule) of the Securities and Exchange Commission.

14.   WITHHOLDING OF TAXES ON EXERCISE OF OPTION

         Except as otherwise provided below, any tax liabilities incurred in
connection with the exercise of an Option under the Plan shall be satisfied by
the withholding of a portion of the Shares underlying the Option exercised
having a Fair Market Value approximately equal to the minimum amount of taxes
required to be withheld under applicable law. Notwithstanding the foregoing, the
Committee may permit an Optionee to pay to the Sponsor in cash all or a portion
of the taxes to be withheld upon the exercise of an Option. In all cases, the
Shares so withheld shall have a Fair Market Value that does not exceed the
amount of taxes to be withheld minus the cash withholding payment, if any, made
by the Optionee. Any election pursuant to this Paragraph 14 must be delivered at
the time of delivery of the notice of exercise. Shares withheld pursuant to this
Paragraph 14 shall be available for subsequent grants under the Plan. The
Committee may add such other reasonable requirements and limitations regarding
elections pursuant to this Paragraph 14 as it deems appropriate. The Sponsor's
obligation to make any delivery or transfer of Shares shall be conditioned on
the recipient's compliance, to the Sponsor's satisfaction, with any withholding
requirement.

15.   EFFECTIVE DATE AND TERM OF PLAN

         The effective date of Plan is the date on which it was adopted by the
Board, as set forth below. The Plan shall expire no later than the tenth
anniversary of the date the Plan was initially adopted by the Board, unless
sooner terminated by the Board.

16.   GENERAL

         The issuance of Shares on the exercise of an Option shall be subject to
all of the applicable requirements of the corporation law of the Sponsor's state
of incorporation and other applicable laws, including federal or state
securities laws, and all Shares issued under the Plan shall be subject to the
terms and restrictions contained in the Certificate of Incorporation of the
Sponsor, as amended from time to time.

Adopted by the Board on the 17th day of November, 1999.
