laws of the jurisdiction of its incorporation, with full corporate power and
authority to conduct its business as now conducted, and is duly qualified or

Material Adverse Effect. Except as set forth on Schedule 2.01, API is not
required to be licensed or qualified to do business as a foreign corporation in
any jurisdiction other than in the State of Tennessee, and no such jurisdiction

                                        4

<PAGE>   10

exhibits, post-effective amendments and supplements thereto) (the "CCA SEC
REPORTS") required to be filed by it under each of the Securities Act of 1933,
as amended, and the rules and regulations promulgated thereunder (the
"SECURITIES ACT"), and the Securities Exchange Act of 1934, as amended, and the
rules and regulations promulgated thereunder (the "EXCHANGE ACT"). As of their
respective dates, the CCA SEC Reports (i) complied as to form in all material
respects with the applicable requirements of the Securities Act and the Exchange
Act, as the case may be, and (ii) except with respect to (A) misstatements or
omissions which would not, individually or in the aggregate, have a material
adverse effect on the business, operations, financial position, results of
operation, prospects or condition (financial or otherwise) of CCA, and/or (B)
alleged misstatements or omissions which formed the factual basis for that
series of class action lawsuits brought against CCA by current and former
stockholders of CCA and its predecessors, which have been definitively settled
pursuant to the terms of settlement agreements receiving final court approvals
in February 2001, did not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances under which they were
made, not misleading. None of CCA's Subsidiaries is required to file any forms,
reports, schedules, statements or other documents with the SEC. Except as
specifically disclosed in the CCA SEC Reports filed prior to the date of this
Agreement, there are no other transactions, agreements, arrangements or
understandings between CCA and its Subsidiaries, on the one hand, and API, on
the other, that would be required to be disclosed under Item 404 of Regulation

the notes, if any, thereto) included in the CCA SEC Reports (collectively, the

condition (financial or otherwise) of CCA, except for such events which have
been previously publicly disseminated by CCA via either (i) press release or

the DCMF Agreement, the Lease or the O&M Contract, have been modified or
amended, or assigned or transferred, except as specified in Schedule 2.13(b).

that the DCMF Agreement, the Lease or the O&M Contract are not in full force and
effect and do not constitute a legal, valid and binding agreement, enforceable
in accordance with its terms, of each party thereto, or that any party thereto
is in violation or breach under any such Contracts (or with notice or lapse of
time or both, would be in violation or breach of or default under any such
Contracts), the effect of which, individually or in the aggregate, would or
could reasonably be expected to have, a Material Adverse Effect.

               (c) No event or condition presently exists which constitutes a
default or breach, or, after notice or lapse of time or both, would constitute a
default or breach by CCA, API, or their respective Subsidiaries, as the case may
be, or, to the knowledge of CCA, any other party thereto, under any of the
Material Contracts or the DCMF Agreement, the Lease or the O&M Contract, the
effect of which, individually or in the aggregate, would have or could
reasonably be expected to have a Material Adverse Effect, and the consummation
of the transactions contemplated hereby will not cause any such default or
breach under any of the Material Contracts, or, to the knowledge of CCA, under
the DCMF Agreement, the Lease or the O&M Contract.

               (d) Neither CCA, API nor any of their respective Subsidiaries,
nor to the knowledge of CCA, any other party, is in violation or breach of or

Agreement, the Lease or the O&M Contract, (ii) the Credit Agreement Documents,
the 12% Note Documents, the Subordinated Note Documents, or (iii) any other
Contract to which CCA or any of its Subsidiaries is a party or by which any of

breach of or default under would have or could reasonably be expected to have a
Material Adverse Effect.

PROCEEDINGS") pending or, to the knowledge of CCA, threatened by or against or
otherwise affecting CCA or any Subsidiary (including API) or their respective
Assets and Properties which could reasonably be expected, if decided in a manner
adverse to CCA or such Subsidiary (including API), to result in liability to API
or which could otherwise have a Material Adverse Effect. There are no Actions or
Proceedings pending or, to the knowledge of CCA, threatened or proposed,

any Governmental Authority with respect to API or any of their respective
officers or directors (present and former) is pending or threatened, nor has any

                   (ii) no Company Plan that is or has ever been subject to
Part 3 of Subtitle B of Title I of ERISA or Section 412 of the Code has incurred
any "accumulated funding deficiency" (as defined therein), whether or not
waived, no liability under Part 3 of Subtitle B of Title I of ERISA or Title IV
of ERISA has been incurred or is expected to be incurred with respect to any
such Company Plan subject thereto (other than premiums incurred and paid when
due), nor has there been any "reportable event" within the meaning of Section
4043(c) of ERISA with respect to any such Company Plan;

accrued benefits under each of the Plans sponsored by CCA, API or any ERISA

IV of ERISA, based upon the interest rate assumptions that would be utilized by
the PBGC to value annuities for a pension plan termination and the other

as of its latest valuation date, exceed the then current value of the assets of
such Company Plan;

                   (iv) no event has occurred and no condition exists with

under Section 4069 or 4212(c) or any other provision of Part 3 of Subtitle B of

would not have been incurred by API 2 or any of its Affiliates but for the
transactions contemplated hereby, or to CCA or API, or (B) a Lien on or after
the Closing under Section 401(a)(29) of the Code or under ERISA with respect to
any property of API 2, CCA, API or any of their Affiliates that would not been
incurred but for the transactions contemplated hereby, or with respect to any
Asset and Property of CCA or API, API 2 or any subsidiary;

                   (v) none of CCA, API or any "party in interest" (as defined
in Section 3(14) of ERISA) or any "disqualified person" (as defined in Section
4975 of the Code) with respect to any Plan, has engaged in a non-exempt
"prohibited transaction" within the meaning of Section 4975 of the Code or
Section 406 of ERISA;

                   (vi) there has been no violation of Section 4980B of the Code
or Sections 601 through 608 of ERISA with respect to any Plan that could result

or any ERISA Affiliate has at any time: (A) had any obligation to contribute to
any "multiemployer plan" as defined in Section 3(37) of ERISA, and (B) withdrawn
in any complete or partial withdrawal from any "multiemployer plan" as defined
in Section 3(37) of ERISA; and, if CCA, API and each ERISA Affiliate were to, as
of the date hereof, completely withdraw from all multiemployer plans in which
any of them participate, or to which any of them otherwise have any obligation
to contribute, none of CCA, API or any ERISA Affiliate would incur any
withdrawal liability, except as set forth on Schedule 2.27; and

complete copies of the applicable following documents have been delivered to
API 2: Forms 5500, financial statements, and actuarial reports for the last
three Company Plan years.

               (b) Without limiting any other provision of this Section 2.27, no
event has occurred and no condition exists, with respect to any Company Plan,
that has subjected or could subject CCA, API or any Company Plan or any
successor thereto, to any Tax, fine, penalty or other liability (other than, in
the case of API and the Company Plans, a liability arising in the normal course
to make contributions or payments, as applicable, when ordinarily due under a
Company Plan with respect to any employee of API). No event has occurred and no
condition exists, with respect to any Company Plan that could subject API or any
of its Affiliates, or any Company Plan maintained by API or any Affiliate
thereof, to any Tax, fine, penalty or other liability, that would not have been
incurred by API or any of its Affiliates, or any such Company Plan, but for the
transactions contemplated hereby. API has no liability for, under, with respect
to or otherwise in connection with any Company Plan, which liability arises
under ERISA or the Code, by virtue of API being aggregated in a controlled group
or affiliated service group with any ERISA Affiliate (other than API) for
purposes of ERISA or the Code at any relevant time prior to the Closing. No
Company Plan other than a Company Plan is or will be directly or indirectly
binding on API 2 by virtue of the transactions contemplated hereby.

2.28 or in the Material Contracts (with respect to API and APM only) and except
for the Note, as of the date of this Agreement, (i) there are no intercompany
Liabilities between API, on the one hand, and CCA, or, to the knowledge of CCA,
any officer, director, Affiliate or Associate of CCA or any Associate of any
such officer, director or Affiliate (other than API), on the other, (ii) neither
CCA nor, to the knowledge of CCA, any such officer, director, Affiliate or
Associate provides or causes to be provided any assets, services or facilities

Affiliate or Associate and (iv) API does not beneficially own, directly or
indirectly, any Investment Assets of CCA or, to the knowledge of CCA, any such
officer, director, Affiliate or Associate. Except as disclosed in Schedule 2.28,
each of the Liabilities and transactions listed in Schedule 2.08(a) was incurred
or engaged in, as the case may be, on an arm's-length basis. Except as disclosed
in Schedule 2.28 or provided in Section 6.07, since the date of the Latest
Balance Sheet, all settlements of intercompany Liabilities between API, on the
one hand, and CCA or, to the knowledge of CCA, any such officer, director,
Affiliate or Associate, on the other, have been made, and all allocations of
intercompany expenses have been applied, in the ordinary course of business
consistent with past practice.

Agreement or on the ability of ANTS or API 2 to perform their respective
obligations hereunder.

after the Closing CCA discovers in its possession or under its control any other
Books and Records, it will promptly deliver such Books and Records to API 2.

        SECTION 4.08 NOTICE AND CURE. Each of CCA and API, on the one hand, and
ANTS and API 2, on the other, will notify the other promptly in writing of, and
contemporaneously will provide such other party with true and complete copies of
any and all information or documents relating to, and will use all commercially
reasonable efforts to cure before the Closing, any event, transaction or
circumstance occurring after the date of this Agreement that causes or will
cause any covenant or agreement of CCA or API, on the one hand, or ANTS or API
2, on the other, under this Agreement to be breached or that renders or will
render untrue any representation or warranty of such party contained in this
Agreement as if the same were made on or as of the date of such event,
transaction or circumstance or will prevent the fulfillment of any condition to
close or delivery requirement of such party. Each party also will notify the
other promptly in writing of, and will use all commercially reasonable efforts
to cure, no later than fifteen (15) days following receipt of any such notice
from the other party (but in no event later than the fifteenth (15th) day after
the date specified in Section 5.01(g)), any violation or breach of any
representation, warranty, covenant or agreement made by such party in this
Agreement, whether occurring or arising before, on or after the date of this
Agreement. No notice given pursuant to this Section 4.08 shall have any effect
on the representations, warranties, covenants or agreements contained in this
Agreement for purposes of determining satisfaction of any condition contained
herein.

        SECTION 4.09 TERMINATION OF EMPLOYEES. Immediately prior to the Closing
or at an earlier time, API shall terminate all of its employees or independent
contractors, as listed on Schedule 2.18, with the result that, as of the
Closing, API shall cease to employ any employees or have any independent
contractors. Any Liabilities owing to any such employees or independent
contractors shall be satisfied in full prior to the Closing, and any Contracts
with such employees or independent contractors shall be terminated.

        SECTION 4.10 CONFIDENTIALITY.

               (a) CCA, ANTS and API 2 each covenant and agree with the other
party that: all discussions and negotiations by the parties with respect to this
Agreement or the transactions contemplated by this Agreement and all information
furnished by or obtained from the other party in connection with this Agreement
or the transactions contemplated by this Agreement are to be kept confidential

generally available to the public other than through a disclosure by any party
or their respective Representatives, (iii) for information that was or becomes
available to any party or any of their respective Representatives on a
non-confidential basis from a person that is not under an obligation (whether
contractual, legal or fiduciary) to keep such information confidential, (iv) to
those directors, officers, employees of the parties hereto, and those
representatives of the parties' legal, accounting and financial advisors, who
need to know of such discussions and negotiations for purposes of evaluating the

may be reasonably necessary to facilitate the consummation of the transactions
contemplated by this Agreement; including, but not limited to, the Authority in
connection with obtaining the Stock Transfer Consent, the Deed of Novation or
any other consents or approvals in connection with this Agreement or the
consummation of the transactions contemplated by this Agreement. Any disclosure
of confidential information proposed to be made by a party pursuant to (i) above
shall only be of such portion of the confidential information as is legally
required to be disclosed after notice to and consultation with the other party.
The obligations of CCA, ANTS and API 2 under this Section 4.10(a) shall survive
the Closing of this transaction or any termination of this Agreement.

               (b) Neither party hereto shall make any public announcement or
release regarding the transactions contemplated by this Agreement without the
prior consent of the other parties, which consent shall not be unreasonably
withheld except as required by applicable Law, the rules and regulations of any
Governmental Authority (including without limitation any regulation of the SEC)
or any rule of the New York Stock Exchange or any other stock exchange on which
the securities of either CCA or the parent company of ANTS, as the case may be,
may be listed in the future. The parties will use their reasonable best efforts
to consult with each other regarding any public announcement or release
contemplated hereby.

               (c) In the event the transactions contemplated by this Agreement
are not consummated, for any reason, ANTS and API 2 will promptly return to CCA
all records, documents and other information provided to them from CCA or API,

information provided to CCA from them, and all parties will treat all such
records and information as confidential.

agreements, representations or warranties contained in this Agreement which has
not been cured as provided in Section 4.08 hereof or waived in writing; (e) by
CCA, if any of the conditions set forth in Article VII hereof have not been
satisfied by the Closing or have not been waived in writing by CCA; (f) by CCA
if the Board of Directors of CCA determines in the exercise of its fiduciary
duties to authorize a Business Combination with respect to or involving API
other than the transactions contemplated by this Agreement; (g) by CCA or by
ANTS and API 2 at any time after April 30, 2001 if the transactions contemplated
by this Agreement shall not have been consummated and such failure to consummate
was not caused by a breach of this Agreement by the terminating party; or (h) by
any party in the event that any Order or Law becomes effective restraining,
enjoining or otherwise prohibiting or making illegal the consummation of the
transactions contemplated by this Agreement.

        SECTION 5.02 EFFECT OF TERMINATION. In the event of the termination of
this Agreement as provided in Section 5.01, in the absence of fraud or willful
breach on the part of ANTS or API 2, on the one hand, or on the part of CCA, on
the other hand, CCA will not have any liability to ANTS or API 2, and neither
ANTS nor API 2 shall have any liability to CCA, as the case may be, under this
Agreement, provided, however, that (i) the provisions of Sections 4.10 and 11.03
herein shall survive such termination and (ii) nothing contained herein shall
relieve any party hereto from liability for fraud or the willful breach of its
representations, warranties, covenants or agreements contained in this
Agreement.

                        CONDITIONS TO OBLIGATIONS OF CCA

                                  ARTICLE VIII
                                  TAX COVENANTS

        SECTION 8.01 SECTION 338 ELECTION.

               (a) API 2 and CCA shall jointly make an election under Section
338(h)(10) of the Code and the Treasury Regulations promulgated under the Code
(the "TREASURY REGULATIONS") and any corresponding or similar elections under
applicable state, local or foreign Tax law (collectively, a "SECTION 338(H)(10)
ELECTION") with respect to the purchase and sale of the Shares in accordance
with the provisions of this Section 8.01.

               (b) CCA and API 2 shall report, in connection with the
determination of income, franchise or other taxes measured by net income, the
transactions being undertaken pursuant to this Agreement in a manner consistent
with the Section 338(h)(10) Election and this Agreement. API 2 shall be
responsible for the preparation of two (2) copies of all forms and documents
required in connection with the Section 338(h)(10) Election (including Internal
Revenue Service Form 8023). Once API 2 properly prepares documents and forms as
may be required by applicable Tax laws to complete and make properly the Section
338(h)(10) Election and timely delivers two (2) copies of such forms and
documents to CCA, CCA shall execute both copies no later than thirty (30) days
following receipt of such forms and timely file one (1) copy of such forms and
documents with its appropriate federal income Tax Return with the United States
Internal Revenue Service and return

                                       27

<PAGE>   33

the other copy to API 2 for timely filing with the Internal Revenue Service
District Director or other appropriate official or office.

               (c) API 2 shall allocate the Purchase Price in the manner
required by Code Section 338 and the regulations thereunder. CCA shall file all
Tax Returns and statements in connection therewith in a manner consistent with
such allocations and shall take no position contrary thereto unless required to
do so by applicable Tax laws. CCA shall have the right to review and approve
(which approval shall not be unreasonably withheld) any such allocations and any
such forms and schedules relating to such allocations, prior to the filing
thereof. Any disputes regarding the allocation or the preparation, execution or
filing of the forms and documents required in connection with making the Section
338(h)(10) Election shall be resolved in an arbitration to be conducted by a Big
Five accounting firm jointly selected by API 2 and CCA (the "SELECTED ACCOUNTING
FIRM"), whose fees shall be borne equally by ANTS and/or API 2, on the one hand,
and by CCA, on the other hand. Each of the parties to this Agreement shall be
bound by the decision of the Selected Accounting Firm rendered in such
arbitration.

               (d) To the extent permitted by state, local or foreign Tax laws,
the principles and procedures of this Section 8.01 shall also apply with respect
to a Section 338(h)(10) Election under state, local, United Kingdom or other
foreign law. CCA shall join with API 2 in making any election similar to the
Section 338(h)(10) Election which is optional under any state, local, United
Kingdom or other foreign law, and shall cooperate and join in any election made
by API 2 to effect such an election so as to treat the transactions contemplated
herein as a sale of assets for state, local, United Kingdom or other foreign
income Tax purposes.

               (e) Subject to the provisions of Section 10.07, CCA shall be
responsible for all federal income Taxes attributable to API for periods ending
on or before the Closing Date (including any Tax resulting from the Code Section
338(h)(10) Election). In addition, CCA shall be liable for any state, local, or
foreign income Tax attributable to an election under the state, local, or
foreign law similar to the election available under Section 338(h)(10) of the
Code. Further, if a state, local or foreign jurisdiction does not have
provisions similar to the election available under Section 338(h)(10) of the
Code, CCA will be liable for any income Tax imposed on API or with respect to
API by such state, local and/or foreign jurisdiction resulting from the
transactions contemplated by this Agreement.

        SECTION 8.02 PREPARATION OF TAX RETURNS. (a) CCA shall prepare and file,
or cause to be prepared and filed, all income and franchise Tax Returns
(including for the avoidance of doubt, any computations and returns required for
UK Tax or VATA purposes) for API for all periods ending on or prior to the
Closing Date which are filed after the Closing Date. Such Tax Returns shall be
prepared in a manner consistent with past practice, unless contrary treatment is
required by an intervening change in Law. CCA shall permit API 2 to review and
comment on each such Tax Return described in the preceding sentence prior to
filing, but CCA shall have the final determination as to information to be
included in such filed returns. To the extent permitted by applicable Law, CCA
shall include any income, gain, loss, deduction or other Tax items for such
periods on its Tax Returns.

                                       28

<PAGE>   34

               (b) For purposes of this Agreement, the amount of Taxes of API
attributable to the pre-Closing portion of any taxable period beginning before
and ending after the Closing Date (the "STRADDLE PERIOD") shall be determined
based upon a hypothetical closing of the taxable year on such Closing Date with
the Closing Date being included in the pre-Closing portion of such Straddle
Period (except to the extent of any extraordinary actions taken by API 2 after
the Closing on the Closing Date); provided, however, real and personal property
Taxes (which are not based on income) shall be determined by reference to the
relative number of days in the pre-Closing and post-Closing portions of such
Straddle Period. Prior to the Closing, CCA shall estimate in good faith the
amount, if any, of Taxes attributable to the pre-Closing portion of any Straddle
Period and shall subtract from such amount any estimated Tax payments made prior
to the Closing Date (the amount so determined being referred to herein as the
"ESTIMATED TAXES DUE"). Following the Closing, API 2 shall prepare and timely
file all Tax Returns of API for the Straddle Period and shall pay and discharge
all Taxes shown to be due on such Tax Returns. If the actual amount of Taxes
attributable to the pre-Closing portion of the Straddle Period, less any
estimated payments made prior to the Closing Date, exceeds the Estimated Taxes
Due, then CCA, subject to the provisions of Section 10.07, shall pay to API 2
the amount of the excess. If the actual amount of Taxes attributable to the
pre-Closing portion of the Straddle Period, less any estimated payments made
prior to the Closing Date, is less than the Estimated Taxes Due, then API 2
shall pay to CCA the amount of the difference. Any payments by CCA or API 2
hereunder shall be made not later than ten (10) days prior to the due date of
the applicable Tax Returns. CCA shall have a reasonable opportunity to review
all such Tax Returns, which shall be provided to CCA no later than fifteen (15)
business days prior to the due date of such Tax Returns.

               (c) Notwithstanding anything to the contrary in this Agreement,
neither API 2 nor CCA shall, or shall permit API to, file any amended Tax Return
relating to API (or otherwise change such Tax Returns) with respect to taxable
periods ending on or prior to the Closing Date without a written consent of the
other party if such amendment adversely affects the other party or API, unless
required to do so by Law.

               (d) Any refunds of the Taxes of API, plus any interest received
with respect thereto from the applicable taxing authorities for any pre-Closing
period (including without limitation) refunds arising from amended Tax Returns
filed after the Closing Date) shall be for the account of CCA and, if received
by ANTS, API 2 or API shall be paid to CCA within ten (10) calendar days after
API 2 or API receives such refund, provided, however, API 2 may elect (or cause
API to elect) to carryback losses from post-closing periods to pre-closing
periods in which case the refunds attributable to such carryback shall be for
the account of API 2. Any refunds or credits of Taxes of API for any Straddle
Period shall be apportioned between CCA and API 2 in the same manner as the
liability for such Taxes is apportioned above (except as described above with
respect to a carryback from a post-closing period).

        SECTION 8.03 RETENTION OF RECORDS. API 2 and CCA shall (and API 2 shall
cause API to) cooperate fully, as and to the extent reasonably requested by the
other party, in connection with the filing of Tax Returns pursuant to this
section and any audit, litigation or other proceeding with respect to Taxes.
Such cooperation shall include the retention and (upon the other party's
request) the provision of records and information which are reasonably relevant
to any such audit,

                                       29

<PAGE>   35

litigation or other proceeding and making employees available on a mutually
convenient basis to provide additional information and explanation of any
material provided hereunder. Each of CCA and API 2 shall (and shall cause API
to) retain all Books and Records and other Corporate Records with respect to Tax
matters pertinent to API relating to any taxable period beginning before the
Closing Date until the expiration of the statute of limitations (and, to the
extent notified by API 2 or CCA, any extensions thereof) of the respective
taxable periods, and to abide by all record retention agreements entered into
with any taxing authority, and to give the other party reasonable written notice
prior to transferring, destroying or discarding any such Books and Records or
other Corporate Records and, if the other party so requests, to allow (or shall
cause API to allow) the other party to take possession of such Books and Records
or other Corporate Records.

                                   ARTICLE IX
                               CLOSING DELIVERIES

        SECTION 9.01 DELIVERIES BY CCA. At the Closing, CCA shall deliver, or
cause to be delivered, to ANTS or API 2 the following (each of which will be
reasonably satisfactory to ANTS or API 2):

               (a) The Certificate to be delivered in accordance with the
provisions of Section 1.01 hereof.

               (b) A certificate of CCA, dated the Closing Date and executed by
the President or the Chief Financial Officer of CCA, on behalf of itself and
API, certifying (i) as to the accuracy, in all material respects, of the
representations and warranties of CCA at and as of the Closing Date and (ii)
that each of CCA and API has performed or complied, in all material respects,
with all of the covenants, agreements, terms, provisions and conditions to be
performed or complied with by each of CCA and API at or prior to the Closing
Date.

               (c) An opinion of Stokes Bartholomew Evans & Petree, P.A., as
counsel to CCA and API, dated the Closing Date, addressed to ANTS and API 2, to
the effect that:

                   (i) Each of CCA and API is a corporation duly organized and
validly existing and in good standing under the laws of the State of Maryland or
Tennessee, as applicable, and has full corporate power and authority to conduct
its business as now conducted. Each of CCA and API is duly qualified or
authorized to do business and is in good standing in all jurisdictions in which
the conduct or nature of its business makes such qualification or licensing
necessary except for those jurisdictions where the failure to so qualify would
not have, individually or in the aggregate, a Material Adverse Effect.

                   (ii) The authorized capital stock of API consists solely of
one thousand (1,000) shares of common stock, no par value per share, of which
one thousand (1,000) shares of common stock are issued and outstanding, all of
which are owned of record by CCA. Such shares have been duly authorized and
validly issued and are fully paid and nonassessable. To the knowledge of such
counsel, there are no other shares of capital stock of API outstanding, there
are no outstanding Options with respect to API or the Shares, and no securities
of API are reserved for

                                       30

<PAGE>   36

issuance for any purpose. Assuming that API 2 acquires the Shares in good faith
and without notice of any adverse claim within the meaning of Section 8-105 of
the Uniform Commercial Code as in effect in Tennessee (the "UCC"), upon the
delivery of the Certificate in accordance with, and in the manner provided in,
Section 1.01 of the Agreement, API 2 will have acquired all of the rights of CCA
in the Shares, free, to our knowledge, of any adverse claim within the meaning
of Section 8-102(a)(i) of the UCC, or any Lien in favor of API.

                   (iii) CCA has all requisite corporate power and authority to
execute, deliver and perform its obligations under the Agreement (including,
without limitation, to own, hold, sell and transfer the Shares). The execution
and delivery by CCA of the Agreement, the performance by CCA of its respective
obligations thereunder and the consummation by CCA of the transactions
contemplated thereby, have been duly and validly authorized by the Board of
Directors of CCA, no other corporate action on the part of CCA or its
shareholders being necessary.

                   (iv) The Agreement has been duly and validly executed and
delivered by CCA and constitutes a legal, valid and binding obligation of CCA,
enforceable against CCA in accordance with its terms, except that such
enforceability may be subject to (i) bankruptcy, liquidation, conservation,
dissolution, insolvency, reorganization, moratorium, fraudulent conveyance or
other similar laws affecting the enforcement of creditors' rights generally and
(ii) the effects of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law), including,
without limitation, (A) the possible unavailability of specific performance,
injunctive relief or any other equitable remedy and (B) concepts of materiality,
reasonableness, good faith and fair dealing.

                   (v) The execution, delivery and performance by CCA of the
Agreement and the consummation of the transactions contemplated hereby did not
and will not (a) conflict with, violate, or result in the breach of any
provision of the charter or bylaws of CCA, API, or any of their respective
Subsidiaries, (b) conflict with or result in a violation or breach of any Law or
Order of which we are aware applicable to CCA, API, or any of their respective
Subsidiaries or Assets and Properties or (c) except as set forth on Schedule
2.04(c) to the Agreement, (i) conflict with or result in a violation or breach
of, (ii) constitute (with or without notice or lapse of time or both) a default
under, (iii) require CCA, API, or any of their respective Subsidiaries to obtain
any consent, approval or action of, make any filing with or give any notice to
any Person as a result or under the terms of, (iv) result in or give to any
Person any right of termination, cancellation, acceleration or modification in
or with respect to, (v) result in or give to any Person any additional rights or
entitlement to increased, additional, accelerated or guaranteed payments under
or (vi) result in the creation or imposition of any Lien upon CCA, API or any of
their respective Subsidiaries or any of their respective Assets and Properties
under, any Material Contract, the Credit Agreement Documents, the 12% Note
Documents and the Subordinated Note Documents, or any Contract or License known
to us to which CCA or API or any of their respective Subsidiaries is a party or
by which any of their respective Assets and Properties is bound; except in the
case of paragraphs (b) and (c)(i)-(vi) only, for such violations, breaches,
defaults, consents or filings, terminations or accelerations or other events or
matters for which the occurrence or the failure to occur would not have a
Material Adverse Effect.

                                    ARTICLE X
                                 INDEMNIFICATION

        SECTION 10.01 SURVIVABILITY. Notwithstanding any right of any party
(whether or not exercised) to investigate the accuracy of the representations
and warranties of the other party contained in this Agreement, CCA, ANTS and API
2 have the right to rely fully upon the representations, warranties, covenants
and agreements of the other parties contained in this Agreement. The
representations, warranties, covenants and agreements of CCA, ANTS and API 2
contained in this Agreement will survive the Closing (a) indefinitely with
respect to the representations and warranties contained in Sections 2.03, 2.05,
2.17, 3.02, 3.05 and 10.06, (b) until three (3) months after the expiration of
all applicable statutes of limitation (including all periods of extension,
whether automatic or permissive) with respect to matters covered by Sections
2.11, 2.12, 2.26, 2.27 and 8.01, (c) until the first anniversary of the Closing
in the case of all other representations and warranties and any covenant or
agreement to be performed in whole or in part on or prior to the Closing or (d)
with respect to each other covenant or agreement contained in this Agreement,
for one (1) year following the last date on which such covenant or agreement is
to be performed, except that any representation, warranty, covenant or agreement
that would otherwise terminate in accordance with clause (a), (b) or (c) above
will continue to survive if a Claim Notice or Indemnity Notice (as applicable)
shall have been timely given under Sections 10.02 and 10.03 on or prior to such
termination date, until the related claim for indemnification has been satisfied
or otherwise resolved as provided in Sections 10.02 and 10.03.

        SECTION 10.02 INDEMNIFICATION.

               (a) Subject to the provisions of Section 10.02(b) hereof, CCA
shall indemnify, defend and hold harmless ANTS and API 2 and each of its
directors, officers, employees, agents and Affiliates in respect of, and from
and against, any and all liabilities and Losses suffered, incurred or sustained
by any of them or to which any of them becomes subject, resulting from, arising
out of or relating to any misrepresentation, breach of warranty or
nonfulfillment of or failure to perform any covenant, obligation, agreement or
condition on the part of CCA or API contained in this Agreement or any
certificate or document of CCA or API delivered pursuant to this Agreement.

               (b) The provisions of Section 10.02(a) notwithstanding, if all
individual Losses claimed by one party hereto relating to breaches of covenants,
obligations, representations and warranties as described above do not exceed
(pound)50,000 (or the equivalent amount of United States dollars) in the
aggregate, they shall all be deemed not to be Losses for which indemnification
is required under this Section 10.02(b), it being intended that there shall be
no liability hereunder for the first (pound)50,000 of Losses incurred by each
party hereto.

        SECTION 10.03 CAP ON INDEMNIFICATION OBLIGATIONS. The provisions of
Sections 10.01 and 10.02 notwithstanding, there shall be no indemnification
hereunder for any Losses which in the aggregate exceed the Purchase Price. It is
expressly agreed that this Section 10.03 shall not apply to the indemnification
provided for in Sections 10.05 and 10.06.

                                       34

        SECTION 10.04 METHOD OF ASSERTING CLAIMS. All claims for indemnification
by any indemnified party under Section 10.02 will be asserted and resolved as
follows:

               (a) In the event any claim or demand in respect of which an
indemnifying party might seek indemnity under this Article X is asserted against
or sought to be collected from such indemnified party by a Person other than
CCA, ANTS, API 2 or any Affiliate thereof (a "THIRD PARTY CLAIM"), the
indemnified party shall deliver a Claim Notice with reasonable promptness to the
indemnifying party. If the indemnified party fails to provide the Claim Notice
with reasonable promptness after the indemnified party receives notice of such
Third Party Claim, the indemnifying party will not be obligated to indemnify the
indemnified party with respect to such Third Party Claim to the extent that the
indemnifying party's ability to defend has been irreparably prejudiced by such
failure of the indemnified party. The indemnifying party will notify the
indemnified party as soon as practicable within the Dispute Period whether the
indemnifying party disputes its liability to the indemnified party under this
Article X and whether the indemnifying party desires, at its sole cost and
expense, to defend the indemnified party against such Third Party Claim.

                   (i) If the indemnifying party notifies the indemnified party
within the Dispute Period that the indemnifying party desires to defend the
indemnified party with respect to the Third Party Claim pursuant to this Section
10.04(a), then the indemnifying party will have the right to defend, with
counsel reasonably satisfactory to the indemnified party, at the sole cost and
expense of the indemnifying party, such Third Party Claim by all appropriate
proceedings, which proceedings will be vigorously and diligently prosecuted by
the indemnifying party to a final conclusion or will be settled at the
discretion of the indemnifying party (but only with the consent of the
indemnified party in the case of any settlement that provides for any relief
other than the payment of monetary damages or that provides for the payment of
monetary damages as to which the indemnified party will not be indemnified in
full pursuant to this Article X). The indemnifying party will have full control
of such defense and proceedings, including any compromise or settlement thereof;
provided, however, that the indemnified party may, at the sole cost and expense
of the indemnified party, at any time prior to the indemnifying party's delivery
of the notice referred to in the first sentence of this clause (i), file any
motion, answer or other pleadings or take any other action that the indemnified
party reasonably believes to be necessary or appropriate to protect its
interests; and provided further, that if requested by the indemnifying party,
the indemnified party will, at the sole cost and expense of the indemnifying
party, provide reasonable cooperation to the indemnifying party in contesting
any Third Party Claim that the indemnifying party elects to contest. The
indemnified party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the indemnifying party pursuant to this
clause (i), and except as provided in the preceding sentence, the indemnified
party will bear its own costs and expenses with respect to such participation.
Notwithstanding the foregoing, the indemnified party may take over the control
of the defense or settlement of a Third Party Claim at any time if it
irrevocably waives its right to indemnity under this Article X with respect to
such Third Party Claim.

                   (ii) If the indemnifying party fails to notify the
indemnified party within the Dispute Period that the indemnifying party desires
to defend the Third Party Claim pursuant to Section 10.04(a), or if the
indemnifying party gives such notice but fails to prosecute vigorously and
diligently or settle the Third Party Claim, or if the indemnifying party fails
to give any notice

                                       35

<PAGE>   41

whatsoever within the Dispute Period, then the indemnified party will have the
right to defend, at the sole cost and expense of the indemnifying party, the
Third Party Claim by all appropriate proceedings, which proceedings will be
prosecuted by the indemnified party in a reasonable manner and in good faith or
will be settled at the discretion of the indemnified party. The indemnified
party will have full control of such defense and proceedings, including any
compromise or settlement thereof; provided, however, that if requested by the
indemnified party, the indemnifying party will, at the sole cost and expense of
the indemnifying party, provide reasonable cooperation to the indemnified party
and its counsel in contesting any Third Party Claim which the indemnified party
is contesting. Notwithstanding the foregoing provisions of this clause (ii), if
the indemnifying party has notified the indemnified party within the Dispute
Period that the indemnifying party disputes its liability hereunder to the
indemnified party with respect to such Third Party Claim and if such dispute is
resolved in favor of the indemnifying party in the manner provided in clause
(iii) below, the indemnifying party will not be required to bear the costs and
expenses of the indemnified party's defense pursuant to this clause (ii) or of
the indemnifying party's participation therein at the indemnified party's
request, and the indemnified party will reimburse the indemnifying party in full
for all reasonable costs and expenses incurred by the indemnifying party in
connection with such litigation. The indemnifying party may participate in, but
not control, any defense or settlement controlled by the indemnified party
pursuant to this clause (ii), and the indemnifying party will bear its own costs
and expenses with respect to such participation.

                   (iii) If the indemnifying party notifies the indemnified
party that it does not dispute its liability to the indemnified party with
respect to the Third Party Claim under Article X or fails to notify the
indemnified party within the Dispute Period whether the indemnifying party
disputes its liability to the indemnified party with respect to such Third Party
Claim, the Loss in the amount specified in the Claim Notice will be conclusively
deemed a liability of the indemnifying party under this Article X and the
indemnifying party shall pay the amount of such Loss to the indemnified party on
demand. If the indemnifying party has timely disputed its liability with respect
to such claim, the indemnifying party and the indemnified party will proceed in
good faith to negotiate a resolution of such dispute, and if not resolved
through negotiations within the Resolution Period, such dispute shall be
resolved by litigation in a court of competent jurisdiction.

               (b) In the event any indemnified party should have a claim under
this Article X against any indemnifying party that does not involve a Third
Party Claim, the indemnified party shall deliver an Indemnity Notice with
reasonable promptness to the indemnifying party. The failure by any indemnified
party to give the Indemnity Notice shall not impair such party's rights
hereunder except to the extent that an indemnifying party demonstrates that it
has been irreparably prejudiced thereby. If the indemnifying party notifies the
indemnified party that it does not dispute the claim described in such Indemnity
Notice or fails to notify the indemnified party within the Dispute Period
whether the indemnifying party disputes the claim described in such Indemnity
Notice, the Loss in the amount specified in the Indemnity Notice will be
conclusively deemed a liability of the indemnifying party under this Article X
and the indemnifying party shall pay the amount of such Loss to the indemnified
party on demand. If the indemnifying party has timely disputed its liability
with respect to such claim, the indemnifying party and the indemnified party
will proceed in good faith to negotiate a resolution of such dispute, and if not
resolved through negotiations within the Resolution Period, such dispute shall
be resolved by litigation in a court of competent jurisdiction.

                                       36

<PAGE>   42

               (c) In the event of any Loss resulting from a misrepresentation,
breach of warranty or nonfulfillment or failure to be performed of any covenant
or agreement contained in this Agreement as to which an indemnified party would
be entitled to claim indemnity under Section 10.02 but for the provisions of
paragraph (c) thereof, such indemnified party may nevertheless deliver a written
notice to the indemnifying party containing the information that would be
required in a Claim Notice or an Indemnity Notice, as applicable, with respect
to such Loss. If the indemnifying party notifies the indemnified party that it
does not dispute the claim described therein or fails to notify the indemnified
party within the Dispute Period whether the indemnifying party disputes the
claim described in such Claim Notice or Indemnity Notice, as the case may be,
the Loss specified in the notice will be conclusively deemed to have been
incurred by the indemnified party for purposes of making the determination set
forth in paragraph (c) of Section 10.02. If the indemnifying party has timely
disputed the claim described in such Claim Notice or Indemnity Notice, as the
case may be, the indemnifying party and the indemnified party will proceed in
good faith to negotiate a resolution of such dispute, and if not resolved
through negotiations within the Resolution Period, such dispute shall be
resolved by litigation in a court of competent jurisdiction.

        SECTION 10.05 TAX INDEMNIFICATION.

               (a) CCA agrees to indemnify, defend and hold harmless API 2, its
affiliates (including API) and the successors to the foregoing (and their
respective shareholders, officers, directors, employees and agents) against (A)
all Taxes imposed on API or asserted against the properties, income or
operations of API for any taxable period of API ending on or prior to the
Closing Date including the pre-Closing portion of any Straddle Period; (B) the
Taxes described in Section 8.01 relating to the election under Code Section
338(h)(10); (C) Taxes of another Person claimed from API as a result of API
being included prior to the Closing Date in a combined, consolidated or unitary
tax group under Treasury Regulations Section 1.1502-6 (or any similar provision
of state, local or foreign Law) or, as a transferee or successor, by contract or
otherwise; and (D) being treated as a member of a group, or having been
controlled by any Person for United Kingdom Tax purposes.

               (b) Each of CCA and API 2 shall notify the other party in writing
within thirty (30) calendar days of receipt of written notice of any pending or
threatened Tax examination, audit or other administrative or judicial proceeding
(a "TAX CONTEST") that could reasonably be expected to result in an
indemnification obligation under this Section 10.05 of such other party pursuant
to this Section 10.05. If the recipient of such notice of a Tax Contest fails to
provide such notice to the other party, it shall not be entitled to
indemnification for any Taxes arising in connection with such Tax Contest, but
only to the extent, if any, that such failure or delay shall have adversely
affected the indemnifying party's ability to defend against, settle, or satisfy
any action, suit or proceeding against it, or any damage, loss, claim or demand
for which the indemnified party is entitled to indemnification hereunder. If a
Tax Contest relates to any pre-Closing period or to any Taxes for which CCA is
liable in full hereunder, CCA shall at its expense control the defense and
settlement of such Tax Contest. If such Tax Contest relates to any post-Closing
period, API 2 shall at its own expense control the defense and settlement of
such Tax Contest. Notwithstanding the foregoing CCA shall not agree to any
settlement concerning Taxes for a pre-Closing period which may adversely impact
API 2, API or its Subsidiaries for a post-Closing period or the Tax attributes

                                       37

<PAGE>   43

of API or its Subsidiaries without the prior written consent of API 2, which
consent shall not be unreasonably conditioned or withheld. The party not in
control of the defense shall have the right to be kept fully informed of any
material developments and receive copies of all correspondence and shall have
the right to observe the conduct of any Tax Contest (through attendance at
meetings) at its own expense, including through its own counsel and other
professional experts. API 2 and CCA shall jointly represent and control API in
any Tax Contest relating to a Straddle Period, and fees and expenses related to
such representation shall be paid equally by API 2 and CCA.

               (c) In the event that a dispute arises between CCA and API 2 as
to the amount of Taxes or indemnification or any matter relating to Taxes
attributable to API, the parties shall attempt in good faith to resolve such
dispute, and any agreed upon amount shall be paid to the appropriate party. If
such dispute is not resolved thirty (30) calendar days thereafter, the parties
shall submit the dispute to an independent accounting firm mutually chosen by
API 2 and CCA for resolution, which resolution shall be final, conclusive and
binding on the parties. Notwithstanding anything in the Agreement to the
contrary, the fees and expenses of the independent account firm in resolving
this dispute shall be borne equally by CCA and API 2.

               (d) This Section 10.05 shall survive until three months after the
expiration of the statute of limitations with respect to the applicable Tax
(including all periods of extension, whether automatic or permissive).

        SECTION 10.06 PLAN INDEMNIFICATION. On and after the Closing, API and
API 2 shall not be liable for, or assume, and, CCA and any Affiliate thereof
expressly agree to remain liable for, and to indemnify, defend and hold harmless
ANTS and API 2 and each of their respective directors, officers, employees,
agents and Affiliates in respect of, and from and against all liabilities and
Losses relating or pertaining to any Company Plan, or otherwise pertaining to
the employment or other services of any present or former employees or
independent contractors of API.

        SECTION 10.07 ADDITIONAL TAX INDEMNIFICATION MATTERS. The indemnity
contained in Section 10.05(a) shall not apply:

               (a) to any liability for Tax to the extent that the Tax giving
rise to the same has been paid by CCA;

               (b) to any liability for Tax to the extent that the same shall
have arisen by reason of any act, omission or transaction of API and/or ANTS or
API 2 after the Closing otherwise than by reason of the Section 338(h)(10)
Election or in the ordinary course of the business of API conducted at the time
of Closing or as otherwise described herein;

               (c) to any liability for Tax to the extent that the same would
not have arisen or is increased as a result of any failure by API, ANTS or API 2
to comply with their respective obligations under this Agreement;

               (d) to any liability for Tax to the extent that it would not have
arisen but for the passing of or any change in, after the date of this
Agreement, any Law or Order or an increase in the

                                       38

<PAGE>   44

rate of Tax or any imposition of Tax not actually or prospectively in force at
the date of this Agreement;

               (e) to any liability for Tax to the extent that the liability
giving rise to the claim for the Tax in question results in a current reduction
in Tax;

               (f) to the extent that any amount otherwise subject to the
covenant contained in Section 10.05(a) has been recovered under this Agreement.

        SECTION 10.08 LIMITATION ON TAX LIABILITY. Notwithstanding any other
provisions of this Agreement, CCA shall not be liable for any liability for Tax
under this Agreement where the total liability for the Tax in question would
(but for this Section) have been less than (pound)25,000 in the aggregate.

                                   ARTICLE XI
                                  MISCELLANEOUS

        SECTION 11.01 STATEMENTS AS REPRESENTATIONS. All statements contained in
any certificate, schedule, list, document or other writing delivered by a party
pursuant hereto or in connection with the transactions contemplated hereby shall
be deemed representations and warranties of such party for all purposes of this
Agreement.

        SECTION 11.02 REMEDIES CUMULATIVE. The remedies provided herein shall be
cumulative and shall not preclude the assertion by any party hereto of any other
rights or the seeking of any other remedies against the other party hereto.

        SECTION 11.03 EXPENSES. Each party hereto shall be responsible for all
of its own legal, accounting, and other advisory costs, fees and expenses
incurred in the preparation of this Agreement and the performance of its terms
and provisions subject, however, to the following:

               (a) If the transactions contemplated by this Agreement do not
occur due to the failure to obtain the Stock Transfer Consent or any consent
listed on Schedule 2.06, ANTS' and API 2's liability for any costs, fees and
expenses described above incurred during the period from January 14, 2001 until
the date of termination of this Agreement as the result of the failure to obtain
such consents shall not exceed fifty percent (50%) of its total costs, fees and
expenses incurred during such period, subject to a monetary cap of (pound)40,000
(including VAT)(the "CAP"). CCA shall be responsible for such costs, fees and
expenses of ANTS and API 2 incurred during such period exceeding the Cap and for
fifty percent (50%) of the Cap (the "EXCESS COSTS"). ANTS and API 2 shall
provide to CCA copies of all bills, statements, invoices and such other
supporting documentation reasonably required by CCA to evidence the Excess
Costs. CCA shall pay the Excess Costs promptly within fifteen (15) days
following receipt of such documentation.

               (b) If CCA terminates this Agreement other than pursuant to
Sections 5.01(a), (d), (e), (g) or (h) herein or if API 2 terminates this
Agreement pursuant to Section 5.01(b) herein, CCA shall be responsible for all
of the costs, fees and expenses of ANTS and API 2 described above

                                       39

required by CCA to evidence the Total Costs. CCA shall pay the Total Costs
promptly within thirty (30) days following its receipt of such documentation.

such Stamp Duty on behalf of CCA as soon as practicable after the Closing, and,

irrevocably instruct AMC to pay out of the Retention Amount the amount so
adjudicated as the Stamp Duty to the Stamp Office. The balance, if any, of the
Retention Amount, including all interest thereon, after payment of the Stamp
Duty shall be paid to or on behalf of CCA, as directed by CCA. If the actual
amount of Stamp Duty so adjudicated exceeds the Retention Amount, including all
interest thereon, then CCA shall pay to AMC the amount of the excess not later
than ten (10) days following receipt by CCA of the adjudication, and CCA shall
irrevocably instruct AMC to pay the Stamp Duty to the Stamp Office on its behalf
out of such monies. CCA shall irrevocably instruct AMC to provide to API 2
evidence of the payment of the Stamp Duty promptly following the payment by AMC
on its behalf.

                AMENDMENT TO NONQUALIFIED STOCK OPTION AGREEMENT

         This Amendment is entered into on this 12th day of December, 2000, by
and between Community Bancshares, Inc. (the "Company") and the undersigned
individual ("Grantee").

         WHEREAS, Grantee and the Company entered in Nonqualified Stock Option
Agreements dated March 29, 1996, March 27, 1997 and March 26, 1998 (the
"Agreements"); and

         WHEREAS, Grantee and the Company desire to amend the Agreement as set
forth below;

         NOW, THEREFORE, in consideration of the mutual premises contained
herein and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereby agree to amend
the Agreement by amending Paragraph 3 in its entirety to read as follows:

         Exercise of Option: The Option shall be exercisable at any time
         after the date of grant prior to its lapse as stated in Paragraph
         2. The Option shall be exercised by written notice to the
         Secretary of the Company at the principal executive offices of the
         Company. Payment of the Option price shall be made in cash or
         Company Common Stock that was acquired at least six (6) months
         prior to the exercise of the Option, or a combination thereof. To
         the extent permitted by applicable law, the Option may be
         exercised and the exercise price paid pursuant to arrangements
         with brokerage firms permitted under Regulation T of the Federal
         Reserve Board or successor regulations or statues. Any federal or
         state tax withholding requirements can be satisfied by shares of
         the Company Common Stock acquired pursuant to the Option exercise.

The Agreements shall remain in full force and effect unmodified except as
provided above.

         IN WITNESS WHEREOF, the parties have executed this Amendment as of the
day and year first written above.
