                              AMENDMENT NUMBER ONE
                                       TO
                         BUSINESS DEVELOPMENT AGREEMENT

         This AMENDMENT NUMBER ONE TO BUSINESS DEVELOPMENT AGREEMENT (the
"Amendment") is entered into on this 9th day of June, 2000, by and between
PRISON REALTY TRUST, INC. (formerly, Prison Realty Corporation), a Maryland
corporation (the "Company"), and CORRECTIONS CORPORATION OF AMERICA (formerly
Correctional Management Services Corporation), a Tennessee corporation ("CCA").
For purposes of this Amendment, any reference in this Amendment or any reference
in the Business Development Agreement (as defined) to "Operating Company" shall
be deemed to be a reference to CCA.

                                   WITNESSETH:

         WHEREAS, the Company and CCA are parties to that certain Business
Development Agreement, dated as of May 4, 1999 (the "Business Development
Agreement"), pursuant to which the Company agreed to make certain payments to
CCA;

         WHEREAS, the purpose of the Business Development Agreement was to
engage CCA to perform certain services, on an as-needed basis, designed to
assist the Company in identifying new business, specifically including research
regarding the corrections and detention industry, marketing and other business
development services designed to increase awareness of the Company and the
services it offers to government entities, identifying potential facility sites
and potential tenants, negotiating certain agreements related to the acquisition
of new facility management contracts for the Company's tenants, as well as the
development and construction of additional correctional and detention facilities
and additions to the Company's existing correctional and detention facilities,
and such other services as may have been requested by the Company; and

         WHEREAS, the Company and CCA now desire to amend certain terms and
provisions of the Business Development Agreement.

         NOW, THEREFORE, for and in consideration of the foregoing and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree as follows:

         1.       Effective January 1, 2000, and subject to the terms and
provisions and the satisfaction of the conditions set forth hereinafter, Section
1 of the Business Development Agreement shall be amended by the addition of a
new subsection (c) to Section 1, reading as follows:

                  (c)      The Company shall make no payment, whether in cash or
         other consideration, to Operating Company in satisfaction of its
         obligations under this Agreement prior to the termination of this
         Agreement at the time of the consummation of the Management OPCO Merger
         (the "Payment Date"), provided, that, with respect to any such payments
         that would otherwise be due to Operating Company in respect of this
         Agreement on or prior to the Payment Date, interest shall accrue on all
         such amounts from the due date to the date of

<PAGE>   2

         payment at a rate per annum equal to the applicable non-default rate of
         interest that the Company is required to pay from time to time pursuant
         to Section 2.1(d) of the Company's Amended and Restated Credit
         Agreement, dated as of August 4, 1999, as amended by Waiver and
         Amendment dated June 9, 2000 (the "Credit Agreement"), which interest
         shall be due and payable on the Payment Date. "Management OPCO Merger"
         shall have the meaning set forth in the Credit Agreement.

                  Reference is made to that certain Second Master Amendment to
         Lease Agreements dated June 9, 2000 by and between CCA, as tenant, and
         the Company, as landlord, whereby CCA's payment of Base Rent for the
         period from January 1, 2000 through September 30, 2000 (the "Deferred
         Rent") has been deferred until September 30, 2000, except for specific
         limited amounts payable from time to time as expressly set forth
         therein (the "Limited Rent Payments"). The difference between the
         Deferred Rent and the Limited Rent Payments is referred to herein as
         the "Net Deferred Rent." Notwithstanding the other provisions hereof,
         in the event CCA pays to Company and Company accepts any portion of the
         Net Deferred Rent prior to September 30, 2000 (the "Advance Rent
         Payments"), then, in such event, the Company shall pay to CCA all fees
         accruing hereunder, in the same proportion as the Advance Rent Payments
         bear to the Net Deferred Rent.

                  In addition, in the event the Deferred Rent becomes due and
         payable in full by reason of the occurrence of a default by the Tenant
         under Paragraph 3 of the Second Master Amendment to Lease Agreements,
         then all fees which would have been payable by the Company under the
         Business Development Agreement as of the date of the acceleration of
         such Deferred Rent, had such fees not been deferred pursuant to this
         Amendment shall become immediately due and payable to CCA.

         2.       Authorization. Each party to the Amendment hereby represents
and warrants that the execution, delivery, and performance of the Amendment are
within the powers of each party and have been duly authorized by the party, the
execution and performance of this Amendment by each party have been duly
authorized by all applicable laws and regulations, and this Amendment
constitutes the valid and enforceable obligation of each party in accordance
with its terms.

         3.       Effect of Amendment. Except as modified or amended herein, all
terms and provisions of the Business Development Agreement shall continue and
remain in full force and effect.

         4.       Counterparts. This Amendment may be executed in any number of
counterparts, each of which shall be an original, and all of which shall
together constitute one agreement.

         5.       Headings. Section headings are for convenience or reference
only and shall not be used to construe the meaning of any provision in this
Amendment.

         6.       Governing Law. This Amendment shall be construed in accordance
with the laws of the State of Tennessee.

         7.       Severability. Should any part of this Amendment be invalid or
unenforceable, such invalidity or unenforceability shall not affect the validity
and enforceability of the remaining portion.

         8.       Successors. This Amendment shall be binding upon and inure to
the benefit of the respective parties and their permitted assigns and successors
in interest.

         9.       Waivers. No waiver of any breach of any of the terms or
conditions of this Amendment shall be held to be a waiver of any other or
subsequent breach; nor shall any waiver be valid or binding unless the same
shall be in writing and signed by the party alleged to have granted the waiver.

         10.      Entire Agreement. This Amendment constitutes the entire
agreement of the parties hereto and supersedes all prior agreements and
presentations with respect to the subject matter hereof.

         11.      Condition. It is an express condition of this Amendment that
the provisions hereof shall be effective only upon the Company's receipt of such
resolutions and/or fairness opinions as may be required pursuant to that certain
First Supplemental Indenture between the Company and State Street Bank and Trust
Company, as trustee, dated as of June 11, 1999. The Company agrees to provide to
CCA copies of all such resolutions and/or fairness opinions promptly following
receipt thereof by the Company.
