      WHEREAS, the Company has adopted the Amended and Restated Corrections
Corporation of America 2000 Stock Incentive Plan (the "Plan"), which authorizes

      WHEREAS, the Company and Optionee wish to confirm the terms and conditions
of an Option granted to Optionee on __________, 20___ (the "Date of Grant").

      NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained herein, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, it is agreed between the parties
hereto as follows:

      1. Definitions. Except as provided in this Agreement, or unless the
context otherwise requires, the terms used herein shall have the same meaning as
in the Plan.

      2. Grant of Option. Upon and subject to the terms, restrictions,

an Option to purchase up to _________ shares of the Company's Common Stock
(collectively, the "Option Shares").

      3. Option Price. The purchase price per Option Share shall be $______ (the
"Option Price")

      4. Exercise; Vesting; Forfeiture.

            (i) Except as otherwise provided herein, Optionee shall have the
right to exercise the Option, if and to the extent the Option has vested in
accordance with subparagraphs (iii) and (iv) below, at any time during the
ten-year period commencing on the Date of Grant; provided, however, that except
as otherwise provided in subparagraph (iv) below, Optionee may not exercise the
Option unless Optionee is on the date of exercise and continuously after the
Date of Grant an employee of: (a) the Company; (b) an Affiliate Corporation; or
(c) a corporation issuing or assuming the Option in a Transaction to which Code
Section 424 applies (or a Subsidiary Corporation of such corporation) ((a), (b)
and (c) known collectively, herein, as the "Employer").

            (ii) The Option shall be exercised by giving written notice of such
exercise to the Company in the form attached hereto as Exhibit A; provided,
however, that an Option may not be exercised at any one time as to fewer than
one hundred (100) shares (or such number of shares as to which the Option is
then exercisable if such number of shares is less than one

hundred (100)). The Option Price shall be paid or satisfied in full, at the time
of exercise, in cash, in shares of Common Stock owned by Optionee for at least
six months having a Fair Market Value equal to such Option Price or in a
combination of cash and such shares of Common Stock. In addition, payment may
also be made in whole or in part in the form of an option to acquire Common
Stock or in the form of another Award (based, in each case, on the Fair Market
Value of such option or Award on the date the Option is exercised, as determined
by the Committee).

      (iii) Subject to the provisions of subparagraph (iv) below, the Option
shall vest with respect to ______ of the Option Shares on each Vesting Date (as
herein defined). For purposes hereof, the term "Vesting Date" shall mean each of
the following ____ dates: _______________________.

      (iv) In the event that: (a) Optionee dies while in the employ of the
Employer or within three (3) months after the termination of employment with
Employer for any reason; or (b) Optionee's employment with the Employer
terminates by reason of Optionee's Disability, then in any such case the Option
shall vest in full and may be, unless earlier terminated or expired, exercised
by Optionee (or by Optionee's estate or by a person who acquired the right to
exercise such Option by bequest or inheritance or otherwise by reason of the
death or Disability of Optionee) at any time during the stated term of the
Option. For the purpose of this Agreement and notwithstanding any provision(s)
of the Plan or this Agreement to the contrary, subject to the preceding
sentence, in the event Optionee's employment with the Employer is terminated due
to Retirement (other than as the result of Optionee's death or Disability) prior
to ________, 20__, then the Option, to the extent the Option has vested and
unless it earlier terminates or expires, may be exercised at any time during the
stated term of the Option, with the unvested portion of the Option being
forfeited. In the event Optionee's employment with Employer is terminated due to
Retirement (including as the result of Optionee's death or Disability) on or
following __________, 20___, unless terminated or expired, the Option shall
become immediately vested and nonforfeitable for the ten-year period following
the Date of Grant. In the event that there occurs a Change of Control, then in
such case the Option shall vest in full and, unless earlier terminated or
expired, may be exercised by Optionee (or by Optionee's estate or by a person
who acquired the right to exercise such Option by bequest or inheritance or
otherwise by reason of the death or Disability of Optionee) within one (1) year
following the Change in Control. Subject to the first sentence of this
subparagraph (iv), in the event that Optionee's employment with the Employer
terminates other than by reason of Optionee's death or Disability, then the
Option, to the extent the Option has vested and unless it earlier terminates or
expires, may be exercised within three (3) months following the termination of
such employment, with the unvested portion of the Option being forfeited.
Nothing in this Agreement or in any Option granted pursuant hereto shall confer
upon Optionee any right to continue in the employ or service of the Employer or
interfere in any way with the right of the Employer to terminate Optionee's
employment at any time.

      5. Option and Option Shares Subject to Plan. The Option and the Option
Shares shall be subject to, and the Company and Optionee agree to be bound by,

      6. Covenants and Representations of Optionee. Optionee represents,

            (i) Optionee is not acquiring the Option Shares based upon any

            (ii) Optionee is able to bear the economic risks of the investment
in the Option Shares, including the risk of a complete loss of his or her
investment therein;

            (iii) Optionee understands and agrees that the Option Shares may be

the registration of securities for sale, and in such event will be issued and
sold in reliance on exemptions from registration under appropriate state laws;

            (iv) The Option Shares cannot be offered for sale, sold or
transferred by Optionee other than pursuant to: (A) an effective registration

placed on the certificate or certificates delivered to Optionee and any transfer
agent of the Company may be instructed to require compliance therewith;

            (vii) Optionee realizes that the purchase of the Option Shares is a
speculative investment and that any possible profit therefrom is uncertain;

            (ix) The agreements, representations, warranties and covenants made
by Optionee herein extend to and apply to all of the Common Stock of the Company
issued to Optionee from time to time pursuant to this Option. Acceptance by

the exercise of the Option granted hereunder, Optionee shall remit in cash to
the Company the minimum amount of federal and state income and employment tax
withholding which the Company is required to remit to the Internal Revenue
Service or applicable state department of revenue in accordance with the then
current provisions of the Code or applicable state law. Optionee shall pay the
full amount of such withholding simultaneously with the exercise of the Option
or upon the occurrence of any other event that results in the recognition of
compensation income by Optionee. The failure by Optionee to remit the full
amount of withholding due may, in the discretion of the Company, result in the
forfeiture of the related benefit notwithstanding any other provision of this
Agreement.

      8. Governing Law. This Agreement shall be construed, administered and
enforced according to the laws of the State of Maryland, without regard to the
conflicts of laws provisions thereof; provided, however, the Option may not be

United States mail, return receipt requested, postage prepaid, addressed to the
proposed recipient at the last known address of such recipient. Any party may
designate any other address to which notices shall be sent by giving notice of
such address to the other parties in the same manner provided herein.

      11. Severability. In the event that any one or more of the provisions or
portion thereof contained in this Agreement shall for any reason be held to be
invalid, illegal or unenforceable in any respect, the same shall not invalidate
or otherwise affect any other provisions of this Agreement and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision or
portion thereof had never been contained herein.
