                               SEVERANCE AGREEMENT

               This SEVERANCE AGREEMENT (the "Agreement"), made and entered into
as of the 31st day of December, 1999, by and among Prison Realty Trust, Inc., a
Maryland corporation, whose principal place of business is located at 10 Burton
Hills Blvd., Suite 100, Nashville, Tennessee 37215 (the "Company"), Corrections
Corporation of America, a Tennessee corporation, whose principal place of
business is located at 10 Burton Hills Blvd., Nashville, Tennessee 37215
("CCA"), and D. Robert Crants, III, an individual currently residing in
Nashville, Davidson County, Tennessee (the "Executive").

                                   WITNESSETH:

               WHEREAS, the Executive is currently serving as a member of the
Board of Directors of the Company (the "Board") and President of the Company;
and

               WHEREAS, the Executive has decided to voluntarily resign as an
officer and employee of the Company and as a member of the Board, effective as
of December 31, 1999 (the "Resignation Date").

               NOW, THEREFORE, for and in consideration of the mutual covenants
herein contained and other good and valuable consideration, the Company and the
Executive hereby agree as follows:

               1. Resignation. The Executive shall resign as an officer and
employee of the Company and as a member of the Board as of the Resignation Date.
The Executive and the Company agree that, effective as of the Resignation Date,
any and all existing employment agreements with the Company shall be terminated
and cease to have any effect whatsoever notwithstanding any survival or saving
clauses therein contained, other than with respect to amounts payable to the
Executive thereunder prior to the Resignation Date which remain unpaid, and this
Agreement shall control any and all matters relating to the Executive's
employment and termination thereof following the Resignation Date.

               2. Certain Benefits.

               (a) In consideration of the Executive's valued service to the
Company, the Company shall pay the Executive, on the Resignation Date, a
lump-sum cash payment of $233,750, representing amounts which would otherwise be
payable to the Executive pursuant to an Employment Agreement, dated as of June
1, 1997, by and between the Executive and CCA Prison Realty Trust, a Maryland
real estate investment trust and predecessor in interest to the Company, the net
proceeds of which, less any amounts required to be withheld therefrom by the
Company for income and employment tax purposes, shall be used to immediately
repay a portion of the promissory notes dated May 18, 1999, May 28, 1999 and
July 6, 1999, evidencing the indebtedness of the Executive to the Company in the
aggregate face amount of $1,000,000 made under the Prison Realty Corporation
Executive Equity Loan Plan (the "Plan") and the terms of the Plan (the "Loan").

<PAGE>   2

               (b) On the Resignation Date, CCA shall repurchase from the
Executive one hundred fifty thousand (150,000) shares of the voting common stock
of CCA (representing 75% of the Executive's ownership interest in CCA) for
$300,000 in cash, which represents the economic value that the remaining
shareholders of CCA will receive in the Combination (as defined in Section 2(c)
below), the proceeds of which shall be used to immediately repay a portion of
the remaining Loan.

               (c) Immediately prior to the closing of the merger of CCA with
and into a wholly-owned subsidiary of the Company pursuant to an Agreement and
Plan of Merger (the "Agreement and Plan of Merger"), dated as of December 26,
1999, by and between the Company, CCA Acquisition Sub, Inc., PMSI Acquisition
Sub, Inc., and JJFMSI Acquisition Sub, Inc., each a Tennessee corporation and a
wholly-owned subsidiary of Prison Realty, CCA, Prison Management Services, Inc.,
a Tennessee corporation ("PMSI"), and Juvenile and Jail Facility Management
Services, Inc., a Tennessee corporation ("JJFMSI") (the "Combination"), the
Executive shall sell to the Company, and the Company shall purchase from the
Executive, fifty thousand (50,000) shares of the voting common stock of CCA
(representing the remaining portion of the Executive's ownership interest in
CCA) for $100,000, which represents the economic value that the remaining
shareholders of CCA will receive in the Combination, the proceeds of which shall
be used to immediately repay a portion of the remaining balance of the Loan;
provided, however, that the obligation of the parties hereto to consummate such
purchase and sale of the Executive's interest in CCA shall be subject to the
satisfaction of the conditions set forth in Sections 6.01, 6.02 and 6.05 (except
for the conditions set forth in Sections 6.02(i) and (j) and 6.05(d)) of the
Agreement and Plan of Merger.

               (d) Upon the Resignation Date, the terms of the Plan and Loan
shall be amended by this Agreement such that immediately following the
Resignation Date, the remaining balance of the Loan, as reduced by the payments
set forth in Section 2(a) and Section 2(b) of this Agreement, including all
interest accrued thereon as of December 31, 1999, shall be subject to the
following: (i) interest only payments on the newly constituted Loan (the "New
Loan") shall be due and payable on each of the first three anniversaries of the
Resignation Date, with such interest to be accrued annually at a rate of
two-hundred fifty (250) basis points over the thirty-day LIBOR rate in effect on
such date, and (ii) 33-1/3% of the principal amount of the New Loan, and all
accrued and unpaid interest thereon, shall become due and payable on each of the
fourth, fifth and sixth anniversaries of the Resignation Date. Upon completion
of the stock purchase described in Section 2(c) of this Agreement, the remaining
balance of the New Loan shall be reduced by an additional $100,000, in
accordance with Section 2(c) of this Agreement.

               3. Employee Benefits. Except as expressly provided herein, the
Executive's rights under any employee benefit plan, policy or arrangement
maintained by either the Company or CCA shall be unaffected by this Agreement,
and such rights shall be determined under such plans, policies and arrangements.
Under the terms of such plans, policies and arrangements, any stock options or
similar rights which have not been exercised by the Executive, and any other

                                        2

grants or awards of stock or equity interests in which the Executive has not
become vested, shall be terminated or forfeited to the Company.

               4. Release.

               (a) In consideration of the Company's execution of this
Agreement, the Executive, for himself, and for his representatives, heirs,

and unconditionally releases, acquits and forever discharges the Company, CCA
and their respective subsidiaries, affiliates, divisions, successors and
assigns, officers, employees, directors, consultants, attorneys, agents or other
associated entities of the Company or CCA (the "Released Parties"), with respect
to and from any and all actions, causes of action, suits, debts, sums of money,
attorneys' fees, costs, promises, damages, claims, grievances, arbitrations or
demands whatsoever, known or unknown, in law or equity, by contract, or pursuant
to statute, rule, code or regulation, which the Executive now has or has had
from the beginning of the world until the full execution of this Agreement,
expressly including, without limiting the generality of the foregoing, all
claims arising out of or from or regarding or pertaining to any transaction,
dealing, conduct, act or omission, or any other matters or things relating to
the Executive's employment relationship (including his position as a director)
and/or the termination of the employment relationship, based upon any contract,
whether express or implied, or any allegation of illegal employment practices,

opportunity law, or wage and hour law, as amended, including, but not limited
to, the National Labor Relations Act, Title VII of the Civil Rights Act of 1964,

this Agreement (specifically including the Company's obligations under Section
11 of this Agreement) or impair the right or ability of the Executive to enforce
such provisions in accordance with the terms of this Agreement or pursue any
claim for benefits due under any "employee benefit plan" within the meaning of
Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended.
The Executive acknowledges and agrees that if he should hereafter make any claim
or demand or commence or threaten to commence any action, claim or proceeding
against the Released Parties with respect to any cause, matter or thing which is
released by this Section 4(a) of this Agreement, this Section 4(a) may be raised
as a complete bar to any such action, claim or proceedings.

               (b) In consideration of the Executive's execution of this
Agreement, the Company and CCA, for themselves and for their subsidiaries,
affiliates, divisions, successors and assigns, officers, employees, directors,
consultants, attorneys, agents or other associated entities of the Company and
CCA (the "Company Releasors"), agree to and do hereby irrevocably and
unconditionally release, acquit and forever discharge the Executive, and his
heirs, executors, and

                                        3

administrators (hereinafter collectively referred to as the "Employee
Releasees"), with respect to and from any and all actions, causes of action,
suits, debts, sums of money, attorneys' fees, costs, promises, damages, claims,
grievances, arbitrations or demands whatsoever, known or unknown, in law or
equity, by contract, tort or pursuant to statute, rule, code or regulation,
which the Company Releasors now have or have had from the beginning of the world
until the full execution of this Agreement, relating to the Executive's
employment relationship with the Company; provided, however, that nothing herein
shall release the Employee Releasees from the obligations set forth in this
Agreement (including the New Loan), or impair the right or ability of the
Company to enforce such provisions in accordance with the terms of this
Agreement. The Company Releasors acknowledge and agree that if they should
hereafter make any claim or demand or commence or threaten to commence any
action, claim or proceeding against the Employee Releasees with respect to any
cause, matter or thing which is released by this Section 4(b) of this Agreement,
this Section 4(b) may be raised as a complete bar to any such action, claim or
proceedings.

sole and exclusive property of the Company or CCA, shall not be used by the
Executive for any purpose, and shall not be described or disclosed to any party
or person without the express written consent of the Company or CCA. The
Executive agrees that no copies will be retained of any written Confidential

other electronic storage devices to which the Executive has access in the course
of his employment with the Company or CCA, except with the express written

other similar items, keys, computers, diskettes, other electronic storage
devices, and any copies made thereof, obtained in the course of his employment,

               6. Confidential Nature of this Agreement; Non-disparagement. The
