securities issued by Prison Realty in satisfaction of its existing contractual
obligations. The number of shares of Prison Realty Common Stock Baron shall

PURCHASE AGREEMENT, DATED AS OF JUNE __, 2000, BY AND AMONG PRISON REALTY TRUST,
INC., A MARYLAND CORPORATION; CORRECTIONS CORPORATION OF AMERICA, A TENNESSEE
CORPORATION FORMERLY KNOWN AS CORRECTIONAL MANAGEMENT SERVICES CORPORATION; AND

                       CORRECTIONS CORPORATION OF AMERICA

                          COMMON STOCK PURCHASE WARRANT

                       -----------------------------------

Warrant No.: W-A                                   Date: [September ___, 2000]

        This Warrant Certificate certifies that, _____________, or registered
assigns (collectively, the "Warrantholder"), is the registered holder of this
Common Stock Purchase Warrant expiring on or before the Expiration Date (the
"Warrants") to purchase shares of Common Stock, par value $0.01 per share (the
"Common Stock"), of Corrections Corporation of America, formerly Prison Realty
Trust, Inc., a Maryland corporation (the "Company"). Each Warrant entitles the
Warrantholder, upon exercise at any time and from time to time during the period
from the date of this Warrant through [September __, 2005] (the "Expiration
Date"), to purchase all or a portion of the Warrant Shares at the exercise price
of $0.01 per share (the "Exercise Price"), payable in lawful money of the United
States of America upon surrender of this Warrant Certificate and payment of the
Exercise Price, all subject to the terms, conditions and adjustments herein set
forth.

        Certain capitalized terms used herein and not otherwise defined shall
have the meanings ascribed to them in Section 9 hereto or otherwise those
meanings ascribed to them in the Stock Purchase Agreement.

        1. Duration and Exercise of Warrant; Limitations on Exercise; Payment
of Taxes.

        1.1 Duration and Exercise of Warrant. Subject to the terms and
conditions set forth herein, the Warrant may be exercised, either in whole or
from time to time in part, at the election of the Warrantholder by:

        (a) the surrender of this Warrant to the Company, with a duly executed
Exercise Form (in the form annexed hereto as Exhibit A) specifying that portion
of the Principal Amount to be used

<PAGE>   15



to purchase Warrant Shares, during normal business hours on any Business Day
prior to the Expiration Date (as used in this Agreement, "Business Day" shall
mean a day other than a Saturday, Sunday or a day on which banking institutions
in the State of Maryland are required or authorized to close by applicable law,
regulation or executive order); and

        (b) the delivery of payment to the Company, for the account of the
Company, by cash, by certified or bank cashier's check or by wire transfer of
immediately available funds in accordance with wire instructions that shall be
provided by the Company upon request, of that portion of the Principal Amount
specified in the Exercise Form in lawful money of the United States of America.

        Upon such surrender of the Warrants and payment of the Exercise Price,
the Company shall issue and cause to be delivered with all reasonable dispatch
to, or upon the written order of, the Warrantholder, a certificate or
certificates for the number of full Warrant Shares issuable upon the exercise of
such Warrants. The Company agrees that such Warrant Shares shall be deemed to be
issued to the Warrantholder as the record holder of such Warrant Shares as of
the close of business on the Business Day on which this Warrant shall have been
surrendered and payment made for the Warrant Shares as aforesaid. All Warrant
Certificates surrendered upon exercise of Warrants shall be canceled and
disposed of by the Company.

        1.2 Limitations on Exercise. Notwithstanding anything to the contrary
herein, this Warrant may be exercised only upon receipt by the Company of
approval of any applicable Governmental Authority of the proposed exercise. The
Warrantholder shall not be entitled to exercise this Warrant, or any part
thereof, unless and until such approvals, certificates, legal opinions or other
documents are reasonably acceptable to the Company. The cost of such approvals,
certificates, legal opinions and other documents, if required, shall be borne by
the Warrantholder.

        1.3 Warrant Shares Certificate. A stock certificate or certificates for
the Warrant Shares purchased by the Warrantholder shall be delivered to the
Warrantholder within five Business Days after receipt of the Exercise Form and
receipt of payment of all or a portion of the Principal Amount, as designated in
the Exercise Form. If this Warrant shall have been exercised only in part, the
Company shall, at the time of delivery of the stock certificate or certificates,
deliver to the Warrantholder a new Warrant evidencing the rights to use the
remaining portion of the Principal Amount to purchase Warrant Shares, which new
Warrant shall in all other respects be identical with this Warrant.

        1.4 Payment of Taxes. The issuance of certificates for Warrant Shares
upon the exercise of Warrants shall be made without charge to the Warrantholder
for any documentary stamp or similar stock transfer or other issuance tax in
respect thereto; provided, however, that the Warrantholder shall be required to
pay any and all taxes which may be payable in respect of any transfer involved
in the issuance and delivery of any certificate in a name other than that of the
registered Warrantholder as reflected upon the books of the Company.

        1.5 Divisibility of Warrant; Transfer of Warrant.

        (a) Subject to the provisions of this Section, this Warrant may be
divided upon surrender at the office of the Company located at 10 Burton Hills
Boulevard, Nashville, Tennessee 37215, without charge to the Warrantholder.
Subject to the provisions of this Section, upon such division, the Warrants may
be transferred of record as the then-Warrantholder may specify without charge to
such Warrantholder (other than any applicable transfer taxes).

        (b) Subject to the provisions of this Section, upon surrender of this
Warrant to the Company with a duly executed Assignment Form (in the form annexed
hereto as Exhibit B) and funds sufficient to pay any transfer tax, the Company
shall, without charge, execute and deliver a new Warrant or Warrants which shall
in all material respects be identical with this Warrant, in the name of the
assignee named in such Assignment Form, and this Warrant shall promptly be
canceled. Prior to any proposed transfer (whether as the result of a division or
otherwise) of this Warrant, such Warrantholder shall give written notice to the
Company of such Warrantholder's intention to effect such transfer. Each such
notice shall describe the manner and circumstances of the proposed transfer in
sufficient detail. The term "Warrant" as used in this Agreement shall be deemed
to include any Warrants issued in substitution or exchange for this Warrant.

        2. Reservation and Registration of Shares, etc. The Company covenants
and agrees as follows:

        (a) all Warrant Shares which are issued upon the exercise of this
Warrant will, upon issuance, be validly issued, fully paid and nonassessable,
not subject to any preemptive rights, and free from all taxes, liens, security
interests, charges and other encumbrances with respect to the issue thereof,
other than taxes with respect to any transfer occurring contemporaneously with
such issue;

        (b) during the period within which this Warrant may be exercised, the
Company will at all times have authorized and reserved, and keep available, free
from preemptive rights, out of the aggregate of its authorized but unissued
Common Stock, for the purpose of enabling it to satisfy any obligation to issue
Warrant Shares upon exercise of Warrants, the maximum number of shares of Common
Stock which may then be deliverable upon the exercise of all outstanding
Warrants; and

        (c) the Company will use its reasonable best efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be necessary to enable the Company to perform its
obligations under this Warrant.

        (d) prior to the Expiration Date, the Company shall use its reasonable
best efforts to (i) maintain an effective registration statement covering the
shares of Common Stock of the Company which may then be issuable upon exercise
of all outstanding Warrants and, if necessary, amend and supplement the same and
(ii) make all filings required to obtain all Blue Sky exemptions,
authorizations, consents or approvals required for the issuance of shares of
Common Stock upon exercise of all outstanding Warrants.

<PAGE>   17



        3. Obtaining Stock Exchange Listings. The Company will from time to time
take all action which may be necessary so that the Warrant Shares, immediately
upon their issuance upon the exercise of Warrants, will be listed on the
principal securities exchanges and markets within the United States of America,
if any, on which other shares of Common Stock are listed.

        4. Loss or Destruction of Warrant. Subject to the terms and conditions
hereof, upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant and, in the case of
loss, theft or destruction, of such bond or indemnification as the Company may
reasonably require, and, in the case of such mutilation, upon surrender and
cancellation of this Warrant, the Company will execute and deliver a new Warrant
of like tenor.

        5. Ownership of Warrant. The Company may deem and treat the
Warrantholder as the holder and owner hereof (notwithstanding any notations of
ownership or writing hereon made by anyone other than the Company) for all
purposes and shall not be affected by any notice to the contrary, until
presentation of this Warrant for registration of transfer.

        6. Amendments. Any provision of this Warrant may be amended and the
observance thereof may be waived (either generally or in a particular instance
and either retroactively or prospectively), only with the written consent or
approval of the Company and the Warrantholder. Any amendment or waiver effected
in accordance with this Section 6 shall be binding upon the Warrantholder and
the Company.

        7. Certain Corporate Actions.

        7.1 Distributions to all Holders of Common Stock. If the Company shall,
at any time after the date of issuance of this Warrant, fix a record date to
distribute to all holders of its Common Stock any shares of capital stock of the
Company (other than Common Stock) or evidences of its indebtedness or assets
(not including regular quarterly cash dividends or distributions paid from
retained earnings of the Company) or rights or warrants to subscribe for or
purchase any of its securities [(provided, however, that (i) the distribution of
the Company's Series B Preferred Stock to the existing holders of the Company's
Common Stock and (ii) the issuance of rights to purchase shares of the Company's
Common Stock to existing holders of the Company's Common Stock shall not
constitute such a distribution giving rise to adjustment under this Section
7.1)], then the Warrantholder shall be entitled to receive, upon exercise of
this Warrant, that portion of such distribution to which it would have been
entitled had the Warrantholder exercised its Warrant immediately prior to the
date of such distribution. At the time it fixes the record date for such
distribution, the Company shall allocate sufficient reserves to ensure the
timely and full performance of the provisions of this subsection. The Company
shall promptly (but in any case no later than five Business Days prior to the
record date of such distribution) give notice to the Warrantholder that such
distribution will take place.

<PAGE>   18



        7.2 Changes in Capital Stock. In case at any time the Company shall be a
party to any transaction (including, without limitation, a merger,
consolidation, sale of all or substantially all of the Company's assets,
liquidation or recapitalization of the capital stock) in which the previously
outstanding capital stock shall be changed into or exchanged for different
securities of the Company or common stock or other securities of another
corporation or interest in a non-corporate entity or other property (including
cash) or any combination of any of the foregoing or in which the Common Stock,
if then so listed or traded, ceases to be a publicly traded security either
listed on the New York Stock Exchange or the American Stock Exchange or quoted
by the NASDAQ National Market System or any successor thereto or comparable
system (each such transaction being herein called the "Transaction," the date of
consummation of the Transaction being herein called the "Consummation Date"),
then, as a condition of the consummation of the Transaction, lawful and adequate
provisions shall be made so that each holder of Warrants, upon the exercise
thereof at any time on or after the Consummation Date, shall be entitled to
receive, and such Warrants shall thereafter represent the right to receive, in
lieu of the Common Stock issuable upon such exercise prior to the Consummation
Date, the highest amount of securities or other property to which such holder
would actually have been entitled as a shareholder upon the consummation of the
Transaction if such holder had exercised such Warrants immediately prior
thereto.

        7.3 Prohibited Transactions. Notwithstanding anything contained herein
to the contrary, the Company shall not effect any Transaction unless prior to
the consummation thereof each corporation or entity (other than the Company)
which may be required to deliver any securities or other property upon the
exercise of the Warrant, the surrender of Warrants or the satisfaction of
exercise rights as provided herein shall assume, by written instrument delivered
to the holder of the Warrants, the obligation to deliver to such holder such
securities or other property to which, in accordance with the foregoing
provisions, such holder may be entitled, and such corporation or entity shall
have similarly delivered to the holder of the Warrant appropriate notice of the
changes made in the rights attaching to the Warrants as a result of such
Transaction, including, without limitation, the exercise provisions applicable
thereto, if any, which shall thereafter continue in full force and effect and
shall be enforceable against such corporation or entity in accordance with the
terms hereof and thereof, together with such other matters as such holders may
reasonably request.

        8. Expiration of the Warrant. The obligations of the Company pursuant to
this Warrant shall terminate on the Expiration Date.

CORPORATION FORMERLY KNOWN AS CORRECTIONAL MANAGEMENT SERVICES CORPORATION; AND
BARON ASSET FUND, A MASSACHUSETTS BUSINESS TRUST, AND ALL SERIES THEREOF, ON

                      ------------------------------------

                       CORRECTIONS CORPORATION OF AMERICA

                          COMMON STOCK PURCHASE WARRANT

                       -----------------------------------

Warrant No.: W-B                                    Date:  [September ___, 2000]

        This Warrant Certificate certifies that, _____________, or registered
assigns (collectively, the "Warrantholder"), is the registered holder of this
Common Stock Purchase Warrant expiring on or before the Expiration Date (the
"Warrants") to purchase shares of Common Stock, par value $0.01 per share (the
"Common Stock"), of Corrections Corporation of America, formerly Prison Realty
Trust, Inc., a Maryland corporation (the "Company"). Each Warrant entitles the
Warrantholder, upon exercise at any time and from time to time during the period
from the date of this Warrant through [September __, 2005] (the "Expiration
Date"), to purchase all or a portion of the Warrant Shares at the Exercise
Price, payable in lawful money of the United States of America upon surrender of
this Warrant Certificate and payment of the Exercise Price, all subject to the
terms, conditions and adjustments herein set forth.

        Certain capitalized terms used herein and not otherwise defined shall
have the meanings ascribed to them in Section 9 hereto or otherwise those
meanings ascribed to them in the Stock Purchase Agreement.

        1. Duration and Exercise of Warrant; Limitations on Exercise; Payment of
Taxes.

        1.1 Duration and Exercise of Warrant. Subject to the terms and
conditions set forth herein, the Warrant may be exercised, either in whole or
from time to time in part, at the election of the Warrantholder by:

        (a) the surrender of this Warrant to the Company, with a duly executed
Exercise Form (in the form annexed hereto as Exhibit A) specifying that portion
of the Principal Amount to be used



<PAGE>   26



to purchase Warrant Shares, during normal business hours on any Business Day
prior to the Expiration Date (as used in this Agreement, "Business Day" shall
mean a day other than a Saturday, Sunday or a day on which banking institutions
in the State of Maryland are required or authorized to close by applicable law,
regulation or executive order); and

        (b) the delivery of payment to the Company, for the account of the
Company, by cash, by certified or bank cashier's check or by wire transfer of
immediately available funds in accordance with wire instructions that shall be
provided by the Company upon request, of that portion of the Principal Amount
specified in the Exercise Form in lawful money of the United States of America.

        Upon such surrender of the Warrants and payment of the Exercise Price,
the Company shall issue and cause to be delivered with all reasonable dispatch
to, or upon the written order of, the Warrantholder, a certificate or
certificates for the number of full Warrant Shares issuable upon the exercise of
such Warrants. The Company agrees that such Warrant Shares shall be deemed to be
issued to the Warrantholder as the record holder of such Warrant Shares as of
the close of business on the Business Day on which this Warrant shall have been
surrendered and payment made for the Warrant Shares as aforesaid. All Warrant
Certificates surrendered upon exercise of Warrants shall be canceled and
disposed of by the Company.

        1.2 Limitations on Exercise. Notwithstanding anything to the contrary
herein, this Warrant may be exercised only upon receipt by the Company of
approval of any applicable Governmental Authority of the proposed exercise. The
Warrantholder shall not be entitled to exercise this Warrant, or any part
thereof, unless and until such approvals, certificates, legal opinions or other
documents are reasonably acceptable to the Company. The cost of such approvals,
certificates, legal opinions and other documents, if required, shall be borne by
the Warrantholder.

        1.3 Warrant Shares Certificate. A stock certificate or certificates for
the Warrant Shares purchased by the Warrantholder shall be delivered to the
Warrantholder within five Business Days after receipt of the Exercise Form and
receipt of payment of all or a portion of the Principal Amount, as designated in
the Exercise Form. If this Warrant shall have been exercised only in part, the
Company shall, at the time of delivery of the stock certificate or certificates,
deliver to the Warrantholder a new Warrant evidencing the rights to use the
remaining portion of the Principal Amount to purchase Warrant Shares, which new
Warrant shall in all other respects be identical with this Warrant.

        1.4 Payment of Taxes. The issuance of certificates for Warrant Shares
upon the exercise of Warrants shall be made without charge to the Warrantholder
for any documentary stamp or similar stock transfer or other issuance tax in
respect thereto; provided, however, that the Warrantholder shall be required to
pay any and all taxes which may be payable in respect of any transfer involved
in the issuance and delivery of any certificate in a name other than that of the
registered Warrantholder as reflected upon the books of the Company.

        1.5 Divisibility of Warrant; Transfer of Warrant.

        (a) Subject to the provisions of this Section, this Warrant may be
divided upon surrender at the office of the Company located at 10 Burton Hills
Boulevard, Nashville, Tennessee 37215, without charge to the Warrantholder.
Subject to the provisions of this Section, upon such division, the Warrants may
be transferred of record as the then-Warrantholder may specify without charge to
such Warrantholder (other than any applicable transfer taxes).

        (b) Subject to the provisions of this Section, upon surrender of this
Warrant to the Company with a duly executed Assignment Form (in the form annexed
hereto as Exhibit B) and funds sufficient to pay any transfer tax, the Company
shall, without charge, execute and deliver a new Warrant or Warrants which shall
in all material respects be identical with this Warrant, in the name of the
assignee named in such Assignment Form, and this Warrant shall promptly be
canceled. Prior to any proposed transfer (whether as the result of a division or
otherwise) of this Warrant, such Warrantholder shall give written notice to the
Company of such Warrantholder's intention to effect such transfer. Each such
notice shall describe the manner and circumstances of the proposed transfer in
sufficient detail. The term "Warrant" as used in this Agreement shall be deemed
to include any Warrants issued in substitution or exchange for this Warrant.

        2. Reservation and Registration of Shares, etc. The Company covenants
and agrees as follows:

        (a) all Warrant Shares which are issued upon the exercise of this
Warrant will, upon issuance, be validly issued, fully paid and nonassessable,
not subject to any preemptive rights, and free from all taxes, liens, security
interests, charges and other encumbrances with respect to the issue thereof,
other than taxes with respect to any transfer occurring contemporaneously with
such issue;

        (b) during the period within which this Warrant may be exercised, the
Company will at all times have authorized and reserved, and keep available, free
from preemptive rights, out of the aggregate of its authorized but unissued
Common Stock, for the purpose of enabling it to satisfy any obligation to issue
Warrant Shares upon exercise of Warrants, the maximum number of shares of Common
Stock which may then be deliverable upon the exercise of all outstanding
Warrants; and

        (c) the Company will use its reasonable best efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be necessary to enable the Company to perform its
obligations under this Warrant.

        (d) prior to the Expiration Date, the Company shall use its reasonable
best efforts to (i) maintain an effective registration statement covering the
shares of Common Stock of the Company which may then be issuable upon exercise
of all outstanding Warrants and, if necessary, amend and supplement the same and
(ii) make all filings required to obtain all Blue Sky exemptions,
authorizations, consents or approvals required for the issuance of shares of
Common Stock upon exercise of all outstanding Warrants.


                                        3


<PAGE>   28

        3. Obtaining Stock Exchange Listings. The Company will from time to time
take all action which may be necessary so that the Warrant Shares, immediately
upon their issuance upon the exercise of Warrants, will be listed on the
principal securities exchanges and markets within the United States of America,
if any, on which other shares of Common Stock are listed.

        4. Loss or Destruction of Warrant. Subject to the terms and conditions
hereof, upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant and, in the case of
loss, theft or destruction, of such bond or indemnification as the Company may
reasonably require, and, in the case of such mutilation, upon surrender and
cancellation of this Warrant, the Company will execute and deliver a new Warrant
of like tenor.

        5. Ownership of Warrant. The Company may deem and treat the
Warrantholder as the holder and owner hereof (notwithstanding any notations of
ownership or writing hereon made by anyone other than the Company) for all
purposes and shall not be affected by any notice to the contrary, until
presentation of this Warrant for registration of transfer.

        6. Amendments. Any provision of this Warrant may be amended and the
observance thereof may be waived (either generally or in a particular instance
and either retroactively or prospectively), only with the written consent or
approval of the Company and the Warrantholder. Any amendment or waiver effected
in accordance with this Section 6 shall be binding upon the Warrantholder and
the Company.

        7. Adjustments to Exercise Price.

        7.1 Certain Adjustments. Following the date of determination of the
Exercise Price in accordance with the provisions of Section 9 of this Agreement,
the Exercise Price shall be subject to adjustment from time to time as follows:

        (a) Treatment of Stock Dividends, Stock Splits, etc. In case the Company
shall declare a dividend, or make a distribution, on the outstanding shares of
Common Stock, in either case, in shares of Common Stock, or effect a
subdivision, combination, share exchange or consolidation or reclassification of
the outstanding shares of Common Stock into a greater or lesser number of shares
of Common Stock, then, and in each such case, the Exercise Price in effect
immediately prior to such event or the record date therefor, whichever is
earlier, shall be adjusted by multiplying such Exercise Price by a fraction, the
numerator of which is the number of shares of Common Stock that were outstanding
immediately prior to such event and the denominator of which is the number of
shares of Common Stock outstanding immediately after such event. An adjustment
made pursuant to this Section 7.1(a) shall become effective: (i) in the case of
any such dividend or distribution, immediately after the close of business on
the record date for the determination of holders of shares of Common Stock
entitled to receive such dividend or distribution; or (ii) in the case of any
such subdivision, reclassification, consolidation or combination, at the close
of business on the day upon which such corporate action becomes effective.


                                        4


<PAGE>   29



        (b) Certain Federal Income Tax Adjustments. In addition to the
adjustments in Section 7.1(a) above, the Company will be permitted to make such
reductions in the Exercise Price as it considers to be advisable in order that
any event treated for Federal income tax purposes as a dividend of stock or
stock rights will not be taxable to the holders of the shares of Common Stock.

        (c) Minimum Adjustment of Exercise Price. If the amount of any
adjustment of the Exercise Price required pursuant to this Section 7 would be
less than one percent (1%) of the Exercise Price in effect at the time such
adjustment is otherwise so required to be made, such amount shall be carried
forward and adjustment with respect thereto made at the time of and together
with any subsequent adjustment which, together with such amount and any other
amount or amounts so carried forward, shall aggregate at least one percent (1%)
of such Exercise Price; provided that, upon the exercise of any Warrant or
Warrants, all adjustments carried forward and not theretofore made, up to and
including the date of such exercise shall, with respect to the Warrant or
Warrants then converted, be made to the nearest .001 of a cent.

        7.2 Distributions to all Holders of Common Stock. If the Company shall,
at any time after the date of issuance of this Warrant, fix a record date to
distribute to all holders of its Common Stock any shares of capital stock of the
Company (other than Common Stock) or evidences of its indebtedness or assets
(not including regular quarterly cash dividends or distributions paid from
retained earnings of the Company) or rights or warrants to subscribe for or
purchase any of its securities [(provided, however, that (i) the distribution of
the Company's Series B Preferred Stock to the existing holders of the Company's
Common Stock and (ii) the issuance of rights to purchase shares of the Company's
Common Stock to existing holders of the Company's Common Stock shall not
constitute such a distribution giving rise to adjustment under this Section
7.2)], then the Warrantholder shall be entitled to receive, upon exercise of
this Warrant, that portion of such distribution to which it would have been
entitled had the Warrantholder exercised its Warrant immediately prior to the
date of such distribution. At the time it fixes the record date for such
distribution, the Company shall allocate sufficient reserves to ensure the
timely and full performance of the provisions of this subsection. The Company
shall promptly (but in any case no later than five Business Days prior to the
record date of such distribution) give notice to the Warrantholder that such
distribution will take place.

        7.3 Changes in Capital Stock. In case at any time the Company shall be a
party to any transaction (including, without limitation, a merger,
consolidation, sale of all or substantially all of the Company's assets,
liquidation or recapitalization of the capital stock) in which the previously
outstanding capital stock shall be changed into or exchanged for different
securities of the Company or common stock or other securities of another
corporation or interest in a non-corporate entity or other property (including
cash) or any combination of any of the foregoing or in which the Common Stock,
if then so listed or traded, ceases to be a publicly traded security either
listed on the New York Stock Exchange or the American Stock Exchange or quoted
by the NASDAQ National Market System or any successor thereto or comparable
system (each such transaction being herein called the "Transaction," the date of
consummation of the Transaction being herein called the "Consummation Date"),
then, as a condition of the consummation of the Transaction, lawful and


                                        5


<PAGE>   30

adequate provisions shall be made so that each holder of Warrants, upon the
exercise thereof at any time on or after the Consummation Date, shall be
entitled to receive, and such Warrants shall thereafter represent the right to
receive, in lieu of the Common Stock issuable upon such exercise prior to the
Consummation Date, the highest amount of securities or other property to which
such holder would actually have been entitled as a shareholder upon the
consummation of the Transaction if such holder had exercised such Warrants
immediately prior thereto (subject to adjustments from and after the
Consummation Date as nearly equivalent as possible to the adjustment provided
for in this Section 7).

        7.4 Prohibited Transactions. Notwithstanding anything contained herein
to the contrary, the Company shall not effect any Transaction unless prior to
the consummation thereof each corporation or entity (other than the Company)
which may be required to deliver any securities or other property upon the
exercise of the Warrant, the surrender of Warrants or the satisfaction of
exercise rights as provided herein shall assume, by written instrument delivered
to the holder of the Warrants, the obligation to deliver to such holder such
securities or other property to which, in accordance with the foregoing
provisions, such holder may be entitled, and such corporation or entity shall
have similarly delivered to the holder of the Warrant appropriate notice of the
changes made in the rights attaching to the Warrants as a result of such
Transaction, including, without limitation, the exercise provisions applicable
thereto, if any, which shall thereafter continue in full force and effect and
shall be enforceable against such corporation or entity in accordance with the
terms hereof and thereof, together with such other matters as such holders may
reasonably request.

        7.5 Notice of Adjustment. Upon the occurrence of any event requiring an
adjustment of the Exercise Price, then and in each such case the Company shall
promptly deliver to each holder of the Warrants an Officer's Certificate stating
the Exercise Price resulting from such adjustment and the increase or decrease,
if any, in the number of shares of Common Stock issuable upon exercise of the
Warrants, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based.

        7.6 Effect of Failure to Notify. Failure to file any certificate or
notice or to give any notice, or any defect in any certificate or notice,
pursuant to Section 7.5 shall not affect the legality or validity of the
adjustment to the Exercise Price, the number of shares purchasable upon exercise
of this Warrant, or any transaction giving rise thereto.

        8. Expiration of the Warrant. The obligations of the Company pursuant to
this Warrant shall terminate on the Expiration Date.

        9.     Definitions.

        As used herein, unless the context otherwise requires, the following
terms have the following respective meanings:
