                 ADDITIONAL TERMS AND CONDITIONS OF YOUR OPTION

HOW TO EXERCISE YOUR OPTION

o    This Option must be exercised for whole shares only and in increments of
     at least 40 shares per exercise.

o    The Plan is administered by a Stock Option Plan Administrator in the
     Finance Department in the Atlanta office. The Administrator is responsible
     for assisting you in the exercise of your option and maintaining the
     records of the Plan. He may be reached at (770) 779-6537 or 6536. If you
     have questions about your options, how you go about exercising your vested
     options or how the Plan works, please contact the Administrator during
     normal business hours.

EFFECT OF TERMINATION OF EMPLOYMENT. Except as provided below, you must be
employed by PRG, its Subsidiaries or Affiliates on the applicable vesting date
to exercise your Option.

o    TERMINATION OF EMPLOYMENT BY YOU FOR "GOOD REASON" OR BY PRG WITHOUT CAUSE.
     If your employment by PRG, its Subsidiaries or Affiliates terminates by you
     for "Good Reason" or by PRG without "cause" (as each such term is defined
     in your employment letter agreement from John M. Cook, Chief Executive
     Officer of PRG dated January 15, 2001, effective October 26, 2000), (i)
     your Options that are unvested as of the date of termination of your
     employment will all become vested as of the date of the termination of your
     employment, and (ii) you (or your estate) can exercise any portion of your
     vested Options at any time and from time to time up to and including
     twenty-four (24) months after the date of termination of employment. After
     such twenty-four (24) month period, the unexercised, but vested Options
     shall terminate.

o    OTHER TERMINATION OF EMPLOYMENT. If your employment with PRG, its
     Subsidiaries or Affiliates is terminated for any reason other than by you
     for "Good Reason" or by PRG without cause, (i) any unvested Options will
     terminate as of the date of such termination of employment, and (ii) unless
     your employment is terminated for cause, you will have the right, for a
     period of seventy-five (75) days following such termination of employment,
     to exercise any vested Options, after which the unexercised, but vested
     Options shall terminate. If your employment is terminated for cause, all
     vested and unvested Options will terminate as of the date of termination of
     employment.

o    All capitalized terms contained herein that are not otherwise defined
     herein shall have the meaning ascribed to such term in the employment
     letter agreement from John M. Cook dated January 15, 2001, effective
     October 26, 2000 governing the terms of your employment.

other addresses as either of us may designate by notice to the other):

by the other of any provisions in this Agreement will not affect the right to
enforce those provisions. Any waiver by you or PRG of any condition or the
breach of any term or provision in this Agreement, whether by conduct or
otherwise, in any one or more instances, shall apply only to that instance and
will not be deemed to waive conditions or breaches in the future. If any court
of competent jurisdiction holds that any term or provision of this Agreement is

full force and effect, and this Agreement shall be deemed to be amended
automatically to exclude the offending provision. This Agreement may be executed
