                          AGREEMENT AND PLAN OF MERGER


     AGREEMENT  AND  PLAN OF  MERGER,  dated  as of  September  30,  2005  (this
"Agreement"),  by and between  CAVALRY  BANCORP,  INC, a  Tennessee  corporation
("CAVB"),  and  PINNACLE  FINANCIAL  PARTNERS,  INC.,  a  Tennessee  corporation
("PNFP").

                                    RECITALS:

     WHEREAS,  the Boards of Directors of PNFP and CAVB have approved,  and deem
it advisable  and in the best  interests of their  respective  corporations  and
shareholders  to  consummate  the  strategic  business  combination  transaction
provided for herein in which CAVB will,  subject to the terms and conditions set
forth  herein,  merge  with and into  PNFP (the  "Merger"),  so that PNFP is the
surviving corporation (hereinafter sometimes referred to in such capacity as the
"Surviving Corporation") in the Merger;

     WHEREAS, the Boards of Directors of PNFP and CAVB have each determined that
the Merger and the other transactions  contemplated  hereby are consistent with,
and in furtherance of, their respective business strategies and goals;

     WHEREAS,  the parties desire to make certain  representations,  warranties,
covenants and  agreements  in  connection  with the Merger and also to prescribe
certain conditions to the Merger; and

         WHEREAS,  for Federal  income tax  purposes,  it is  intended  that the
Merger will qualify as a  reorganization  under the provisions of Section 368(a)
of the Internal  Revenue Code of 1986, as amended (the "Code"),  and the parties
intend, by executing this Agreement,  to adopt a plan of  reorganization  within
the meaning of Treasury Regulation Section 1.368-2(g).

     NOW, THEREFORE, in consideration of the mutual covenants,  representations,
warranties and agreements  contained  herein,  and intending to be legally bound
hereby, the parties agree as follows:

                                   ARTICLE I
                                   THE MERGER

     1.1 The Merger.

     (a) Subject to the terms and  conditions of this  Agreement,  in accordance
with the Tennessee Business  Corporation Act (the "TBCA"), at the Effective Time
(as  defined  below),  CAVB shall  merge  with and into PNFP.  PNFP shall be the
Surviving  Corporation in the Merger, and shall continue its corporate existence
under the laws of the State of Tennessee.  Upon consummation of the Merger,  the
separate corporate existence of CAVB shall terminate.

     (b) The  parties may by mutual  agreement  at any time change the method of
effecting the  combination  of CAVB and PNFP  including  without  limitation the

                                       1



provisions  of this  Article I, if and to the extent they deem such change to be
desirable, including without limitation to provide for a merger of CAVB with and
into a wholly-owned  subsidiary of PNFP; provided,  however, that no such change
shall (i) alter or change the amount of Merger  Consideration (as defined below)
to be provided to holders of CAVB  Common  Stock (as defined  below) as provided
for in this  Agreement,  (ii)  adversely  affect the tax treatment of holders of
CAVB Common Stock as a result of  receiving  the Merger  Consideration  or (iii)
materially impede or delay consummation of the transactions contemplated by this
Agreement.

     1.2 Effective  Time. The Merger shall become  effective as set forth in the
articles of merger that shall be filed with the  Secretary of State of the State
of  Tennessee  (the  "Tennessee  Secretary")  on  the  Closing  Date.  The  term
"Effective  Time" shall be the date and time when the Merger becomes  effective,
as set forth in the Articles of Merger.

     1.3  Effects of the Merger.  At and after the  Effective  Time,  the Merger
shall have the effects set forth in Section 48-21-108 of the TBCA.

     1.4  Conversion of CAVB Common Stock . At the Effective  Time, by virtue of
the Merger and without any action on the part of CAVB, PNFP or the holder of any
of the following securities:

     (a) Subject to Section 2.2(e), each share of the common stock, no par value
per share, of CAVB (the "CAVB Common Stock") issued and outstanding  immediately
prior to the  Effective  Time,  except for shares of CAVB Common  Stock owned by
CAVB or PNFP (other than  shares of CAVB  Common  Stock held in trust  accounts,
managed accounts and the like, or otherwise held in a fiduciary  capacity,  that
are  beneficially  owned by third  parties  (any such shares held in a fiduciary
capacity by CAVB or PNFP, as the case may be, being referred to herein as "Trust
Account  Shares"))  or shares of CAVB  Common  Stock  held on  account of a debt
previously  contracted  ("DPC  Shares"),  shall be  converted  into the right to
receive 0.95 shares (the "Exchange Ratio") of the common stock,  $1.00 par value
per share, of PNFP (the "PNFP Common Stock") (the "Merger Consideration").

     (b) All of the  shares of CAVB  Common  Stock  converted  into the right to
receive the Merger  Consideration  pursuant to this Article I shall no longer be
outstanding and shall  automatically be cancelled and shall cease to exist as of
the Effective Time, and each certificate previously representing any such shares
of CAVB Common Stock (each, a "Certificate") shall thereafter represent only the
right to receive (i) a  certificate  representing  the number of whole shares of
PNFP Common Stock (defined below),  and (ii) cash in lieu of fractional  shares,
into which the shares of CAVB Common Stock  represented by such Certificate have
been  converted  pursuant to this Section 1.4 and Section  2.2(e).  Certificates
previously  representing  shares of CAVB  Common  Stock shall be  exchanged  for
certificates  representing whole shares of PNFP Common Stock and cash in lieu of
fractional  shares issued in  consideration  therefor upon the surrender of such
Certificates in accordance with Section 2.2, without any interest  thereon.  If,
prior to the Effective Time, the outstanding shares of PNFP Common Stock or CAVB
Common Stock shall have been increased, decreased, changed into or exchanged for
a  different  number  or  kind  of  shares  or  securities  as  a  result  of  a
reorganization, recapitalization, reclassification, stock dividend, stock split,
reverse stock split, or other similar change in  capitalization,  an appropriate
and  proportionate  adjustment  shall be made to the  Exchange  Ratio  per share
payable pursuant to this Agreement.

                                       2



     (c)  Notwithstanding  anything in this  Agreement to the  contrary,  at the
Effective  Time,  all shares of CAVB Capital  Stock (as defined  below) that are
owned by CAVB or PNFP (other than Trust Account  Shares and DPC Shares) shall be
cancelled  and  shall  cease to  exist,  and no  Merger  Consideration  shall be
delivered in exchange therefor.

     1.5 PNFP Capital Stock. At and after the Effective Time, each share of PNFP
Capital Stock (as defined below) issued and outstanding immediately prior to the
Closing Date shall remain  issued and  outstanding  and shall not be affected by
the Merger.

     1.6 Options and Other Stock-Based Awards.

     (a) Effective as of the Effective  Time,  each then  outstanding  option to
purchase  shares  of CAVB  Common  Stock  (each a "CAVB  Stock  Option")  issued
pursuant to the  equity-based  compensation  plans identified in Section 4.11 of
the CAVB  Disclosure  Schedule (the "CAVB Stock Plans") to any current or former
employee or director of, or consultant to, CAVB or any of its  Subsidiaries,  as
defined  below,  shall be assumed by PNFP and shall be  converted  automatically
into an option to purchase a number of shares of PNFP Common  Stock  (rounded to
the nearest  whole  share) (an  "Assumed  Stock  Option")  at an exercise  price
determined  as provided  below (and  otherwise  subject to the terms of the CAVB
Stock Plans and the agreements evidencing the options thereunder):

     (i) The number of shares of PNFP Common  Stock to be subject to the Assumed
Stock  Option  shall be equal to the  product  of the  number  of shares of CAVB
Common Stock subject to the CAVB Stock Option and the Exchange  Ratio,  provided
that  any   fractional   shares  of  PNFP  Common  Stock   resulting  from  such
multiplication shall be rounded to the nearest whole share; and

     (ii) The  exercise  price per share of PNFP Common  Stock under the Assumed
Stock Option shall be equal to the exercise price per share of CAVB Common Stock
under the CAVB Stock Option  divided by the Exchange  Ratio,  provided that such
exercise price shall be rounded to the nearest whole cent.

In the case of any CAVB Stock Option to which Section 421 of the Code applies by
reason  of its  qualification  under  Section  422 of the Code,  the  conversion
formula shall be adjusted,  if necessary,  to comply with Section  424(a) of the
Code.  Except as otherwise  provided herein,  the Assumed Stock Options shall be
subject to the same terms and conditions (including expiration date, vesting and
exercise  provisions) as were applicable to the corresponding CAVB Stock Options
immediately  prior to the  Effective  Time (but taking into  account any changes
thereto, including the acceleration of vesting thereof, provided for in the CAVB
Stock  Plans or other  CAVB  Benefit  Plan,  as defined  below,  or in any award
agreement   thereunder  by  reason  of  this   Agreement  or  the   transactions
contemplated hereby); provided, however, that references to CAVB shall be deemed
to be references to PNFP.

     (b) PNFP has taken all corporate action necessary to reserve for issuance a
sufficient  number of shares  of PNFP  Common  Stock  upon the  exercise  of the
Assumed Stock Options.  On or as soon as practicable  following the Closing Date
(and in no event more than five  business  days after the  Closing  Date),  PNFP
shall file a registration  statement on an appropriate  form or a post-effective

                                       3



amendment to a previously filed registration  statement under the Securities Act
(defined  below) with respect to the issuance of the shares of PNFP Common Stock
subject  to the  Assumed  Stock  Options  and shall use its  reasonable  efforts
consistent with customary  industry  standards to maintain the  effectiveness of
such registration statement or registration statements (and maintain the current
status of the prospectus or prospectuses  contained therein) for so long as such
equity awards remain outstanding.

     1.7 Charter.  Subject to the terms and conditions of this Agreement, at the
Effective Time, the Charter of PNFP, as amended (the "PNFP Articles"),  shall be
the Charter of the Surviving  Corporation until thereafter amended in accordance
with applicable law.

     1.8 Bylaws.  Subject to the terms and conditions of this Agreement,  at the
Effective  Time,  the  Bylaws  of PNFP  shall  be the  Bylaws  of the  Surviving
Corporation until thereafter amended in accordance with applicable law.

     1.9 Tax  Consequences.  It is intended  that the Merger shall  constitute a
"reorganization"  within the  meaning of Section  368(a) of the Code,  that this
Agreement  shall  constitute  a "plan of  reorganization"  for the  purposes  of
Sections 354 and 361 of the Code.

     1.10 Certain Post-Closing Matters.

     (a) Board  Composition.  As of the Effective  Time,  and  continuing  for a
period  consistent with the 3 year staggered terms of directors of PNFP to which
they will be added  following  the Effective  Time,  Ed C. Loughry,  Jr. and two
other Current CAVB Directors,  as defined below, shall be appointed to and shall
serve on the Board of Directors of the  Surviving  Corporation.  For purposes of
this Section 1.10, the term "Current CAVB Directors" shall mean those members of
the CAVB Board of Directors  immediately prior to the public announcement of the
transactions contemplated by this Agreement.

     (b)  Procedure  for   Appointing   Current  CAVB   Directors  to  Surviving
Corporation's Board of Directors. Within thirty (30) days after the date of this
Agreement,  the  nominating and corporate  governance  committee of the Board of
Directors  of CAVB shall  submit the names of Ed C.  Loughry,  Jr. and two other
Current CAVB Directors to the nominating and corporate  governance  committee of
PNFP for  consideration  of nomination  to fill three  vacancies on the Board of
Directors of the Surviving  Corporation as of the Effective Time. The nominating
and corporate  governance  committee of PNFP's Board of Directors shall nominate
such  persons  to fill such  vacancies.  The Board of  Directors  of PNFP  shall
promptly meet to consider the appointment of such persons to fill such vacancies
and shall appoint such persons at such meeting if such persons, other than Ed C.
Loughry,  Jr., are  reasonably  acceptable  candidates  to serve on the Board of

                        DELIVERY OF MERGER CONSIDERATION

     2.1 Deposit of Merger  Consideration.  Prior to the  Effective  Time,  PNFP
shall  deposit,  or shall cause to be  deposited,  with a bank or trust  company
reasonably  acceptable to each of CAVB and PNFP (the "Exchange Agent"),  for the
benefit of the holders of  Certificates,  for exchange in  accordance  with this
Article II,  certificates  representing the shares of PNFP Common Stock and cash
in lieu of any fractional  shares (such cash and certificates for shares of PNFP
Common Stock, together with any dividends or distributions with respect thereto,
being hereinafter  referred to as the "Exchange Fund"), to be issued pursuant to
Section 1.4 and paid pursuant to Section 1.4 and Section  2.2(e) in exchange for
outstanding shares of CAVB Common Stock.

     2.2 Delivery of Merger Consideration.

     (a) As soon as practicable,  but in no event later than five business days,
after the Effective Time, the Exchange Agent shall mail to each holder of record
of one or more  Certificates  a  letter  of  transmittal  in  customary  form as
reasonably  agreed by the parties  (which shall specify that  delivery  shall be
effected,  and risk of loss and title to the Certificates  shall pass, only upon
delivery of the  Certificates to the Exchange Agent) and instructions for use in
effecting  the  surrender  of the  Certificates  in  exchange  for  certificates
representing  the shares of PNFP Common Stock and any cash in lieu of fractional
shares  into  which  the  shares  of  CAVB  Common  Stock  represented  by  such
Certificate  or  Certificates   shall  have  been  converted  pursuant  to  this
Agreement.  Upon proper  surrender to the  Exchange  Agent of a  Certificate  or
Certificates  for  exchange  and  cancellation,   together  with  such  properly
completed  and duly executed  letter of  transmittal  as the Exchange  Agent may
reasonable  require,  the holder of such  Certificate or  Certificates  shall be
entitled to receive in  exchange  therefor,  as  applicable,  (i) a  certificate
representing  that  number of whole  shares of PNFP  Common  Stock to which such
holder  of  CAVB  Common  Stock  shall  have  become  entitled  pursuant  to the
provisions of Article I and (ii) a check  representing the amount of any cash in
lieu of fractional  shares which such holder has the right to receive in respect
of the  Certificate or  Certificates  surrendered  pursuant to the provisions of
this  Article II, and the  Certificate  or  Certificates  so  surrendered  shall
forthwith be  cancelled.  No interest  will be paid or accrued on any cash or on
any unpaid dividends and distributions payable to holders of Certificates.

     (b) No  dividends  or other  distributions  declared  with  respect to PNFP
Common Stock shall be paid to the holder of any unsurrendered  Certificate until
the holder  thereof shall  surrender such  Certificate  in accordance  with this
Article II. After the surrender of a Certificate in accordance with this Article

                                       5



II, the record holder thereof shall be entitled to receive any such dividends or
other distributions,  without any interest thereon, which theretofore had become
payable  with  respect  to  shares  of PNFP  Common  Stock  represented  by such
Certificate.

     (c) If any  certificate  representing  shares of PNFP Common Stock is to be
issued  in a name  other  than  that in which the  Certificate  or  Certificates
surrendered in exchange  therefor is or are registered,  it shall be a condition
of the issuance  thereof that the  Certificate  or  Certificates  so surrendered
shall be properly  endorsed (or  accompanied  by an  appropriate  instrument  of
transfer)  and  otherwise  in  proper  form for  transfer,  and that the  person
requesting such exchange shall pay to the Exchange Agent in advance any transfer
or other taxes required by reason of the issuance of a certificate  representing
shares of PNFP Common Stock in any name other than that of the registered holder
of the  Certificate  or  Certificates  surrendered,  or  required  for any other
reason,  or shall establish to the  satisfaction of the Exchange Agent that such
tax has been paid or is not payable.

     (d) After the  Effective  Time,  there shall be no  transfers  on the stock
transfer  books of CAVB of the shares of CAVB Common  Stock that were issued and
outstanding  immediately  prior to the Effective  Time.  If, after the Effective
Time,  certificates  representing  such shares are presented for transfer to the
Exchange  Agent,   they  shall  be  cancelled  and  exchanged  for  certificates
representing  shares  of PNFP  Common  Stock and cash for  fractional  shares as
provided in this Article II.

     (e)   Notwithstanding   anything  to  the  contrary  contained  herein,  no
certificates or scrip representing  fractional shares of PNFP Common Stock shall
be issued  upon the  surrender  for  exchange  of  Certificates,  no dividend or
distribution  with  respect  to PNFP  Common  Stock  shall be payable on or with
respect to any fractional  share,  and such fractional share interests shall not
entitle the owner  thereof to vote or to any other  rights of a  shareholder  of
PNFP. In lieu of the issuance of any such  fractional  share,  PNFP shall pay to
each former  shareholder of CAVB who otherwise would be entitled to receive such
fractional  share an amount in cash determined by multiplying (i) the average of
the closing-sale  prices of PNFP Common Stock on the securities  market or stock
exchange in which the PNFP Common Stock  principally  trades, as reported by The
Wall Street Journal for the five trading days immediately  preceding the date of
the  Effective  Time by (ii) the  fraction  of a share  (rounded  to the nearest
thousandth  when  expressed in decimal  form) of PNFP Common Stock to which such
holder would otherwise be entitled to receive pursuant to Section 1.4.

     (f)  Any  portion  of the  Exchange  Fund  that  remains  unclaimed  by the
shareholders of CAVB as of the first  anniversary of the Effective Time shall be
paid to PNFP. Any former shareholders of CAVB who have not theretofore  complied
with this  Article  II shall  thereafter  look only to PNFP for  payment  of the
shares of PNFP Common  Stock and cash in lieu of any  fractional  shares and any
unpaid  dividends  and  distributions  on the PNFP Common Stock  deliverable  in
respect of each share of CAVB Common Stock such shareholder  holds as determined
pursuant  to this  Agreement,  in  each  case,  without  any  interest  thereon.
Notwithstanding  the  foregoing,  none of CAVB,  PNFP, the Exchange Agent or any
other person shall be liable to any former holder of shares of CAVB Common Stock
for any  amount  delivered  in good  faith  to a  public  official  pursuant  to
applicable abandoned property, escheat or similar laws.

                                       6



     (g) In the event any Certificate shall have been lost, stolen or destroyed,
upon the  making  of an  affidavit  of that  fact by the  person  claiming  such
Certificate to be lost, stolen or destroyed and, if reasonably required by PNFP,
the  posting by such person of a bond in such  amount as PNFP may  determine  is
reasonably  necessary as indemnity against any claim that may be made against it
with respect to such Certificate,  the Exchange Agent will issue in exchange for
such lost, stolen or destroyed  Certificate the shares of PNFP Common Stock, and
any cash in lieu of fractional shares deliverable in respect thereof pursuant to
this Agreement.

                                  ARTICLE III.
                     REPRESENTATIONS AND WARRANTIES OF PNFP

     Except as disclosed in (a) the PNFP Reports  (defined below) filed prior to
the date hereof or (b) the disclosure schedule (the "PNFP Disclosure  Schedule")
delivered  by PNFP to CAVB  prior  to the  execution  of this  Agreement  (which
schedule  sets  forth,  among other  things,  items the  disclosure  of which is
necessary or appropriate either in response to an express disclosure requirement
contained   in  a  provision   hereof  or  as  an   exception  to  one  or  more
representations or warranties contained in this Article III or to one or more of
PNFP's   covenants   contained   in  Article   V,   provided,   however,   that,
notwithstanding  anything in this Agreement to the contrary, (i) no such item is
required to be set forth in such schedule as an exception to a representation or
warranty  if its  absence  would not  result in the  related  representation  or
warranty  being deemed  untrue or incorrect  under the standard  established  by
Section  9.2,  and (ii) the mere  inclusion  of an item in such  schedule  as an
exception to a representation  or warranty shall not be deemed an admission that
such  item  represents  a  material   exception  or  material  fact,   event  or
circumstance  or that such item has had or would be reasonably  likely to have a
Material Adverse Effect (as defined below) on PNFP),  PNFP hereby represents and
warrants to CAVB as follows:

standing under the laws of the State of Tennessee.  PNFP has the corporate power
and authority to own or lease all of its  properties  and assets and to carry on
its business as it is now being conducted,  and is duly licensed or qualified to
do business in each  jurisdiction in which the nature of the business  conducted
by it or the character or location of the  properties and assets owned or leased
by it makes such licensing or qualification necessary,  except where the failure
to be so  licensed  or  qualified  would  not,  either  individually  or in  the
aggregate,  have a Material  Adverse Effect on PNFP. As used in this  Agreement,
the term  "Material  Adverse  Effect" means,  with respect to CAVB,  PNFP or the
Surviving Corporation,  as the case may be, a material adverse effect on (i) the
business, operations, results of operations or financial condition of such party
and its  Subsidiaries  taken as a whole or which might have a financial  cost to
PNFP after the Merger of at least $500,000 taking into account, for example with
respect to Regulatory  Agreements,  the aggregate  costs to PNFP of  compliance,
personnel  costs,  appeals,  fines,  legal,  accounting,  or consulting fees, or
restrictions  on future  expansion,  or (ii) the ability of such party to timely
consummate the transactions  contemplated hereby;  provided,  however, that with
respect  to clause  (i),  the  following  shall not be deemed to have a Material
Adverse  Effect:  any change or event caused by or resulting from (A) changes in
prevailing interest rates, currency exchange rates or other economic or monetary
conditions in the United  States or  elsewhere,  (B) changes in United States or
foreign  securities  markets,  including  changes  in price  levels  or  trading

                                       7

hereof, in generally  accepted  accounting  principles or regulatory  accounting
requirements  applicable  to banks or  savings  associations  and their  holding
companies  generally,  (E)  changes,  after the date hereof,  in laws,  rules or
regulations  of  general   applicability  or  interpretations   thereof  by  any
Governmental Entity (as defined below), (F) actions or omissions of PNFP or CAVB
taken with the prior written consent of the other or required hereunder, (G) the
execution and delivery of this Agreement or the consummation of the transactions
contemplated  hereby or the announcement  thereof,  or (H) any outbreak of major
hostilities  in which the  United  States is  involved  or any act of  terrorism
within the United States or directed against its facilities or citizens wherever
located; and provided,  further,  that in no event shall a change in the trading
prices  of a party's  capital  stock,  by  itself,  be  considered  material  or
constitute a Material Adverse Effect.

     (b) PNFP is a bank  holding  company  registered  under  the  Bank  Holding
Company Act of 1956, as amended (the "BHC Act"). True and complete copies of the
PNFP Articles and Bylaws of PNFP, as in effect as of the date of this Agreement,

local or foreign)  where its  ownership or leasing of property or the conduct of
its business  requires it to be so  qualified  and in which the failure to be so
qualified  would  have a  Material  Adverse  Effect  on PNFP and  (iii)  has all
requisite  corporate or other power and authority to own or lease its properties
and assets and to carry on its business as now  conducted,  except to the extent
that the failure to have such power or  authority  will not result in a Material
Adverse Effect on PNFP. As used in this Agreement,  the word  "Subsidiary"  when
used with  respect  to any party  means any  bank,  savings  bank,  corporation,
partnership,   limited  liability  company,  or  other   organization,   whether

consistently  applied  during the periods  involved,  except,  in each case,  as
indicated in such  statements or in the notes thereto.  The books and records of
PNFP and its Subsidiaries  have been, and are being,  maintained in all material
respects in accordance with GAAP and any other  applicable  legal and accounting
requirements and reflect only actual transactions.

     3.7 Broker's  Fees.  Except for Raymond James & Associates,  Inc.,  neither
PNFP nor any PNFP Subsidiary nor any of their  respective  officers or directors
has  employed any broker or finder or incurred  any  liability  for any broker's
fees,  commissions  or finder's  fees in  connection  with the Merger or related
transactions contemplated by this Agreement.

     3.8 Absence of Certain Changes or Events.

     (a) Since June 30, 2005,  no event or events have  occurred  that have had,
either individually or in the aggregate, a Material Adverse Effect on PNFP.

     (b) Since June 30, 2005,  through and including the date of this Agreement,
PNFP and its  Subsidiaries  have carried on their  respective  businesses in all
material respects in the ordinary course.

     3.9 Legal Proceedings.

     (a) Except as disclosed in Section 3.9(a) of the PNFP Disclosure  Schedule,
neither  PNFP nor any of its  Subsidiaries  is a party to any,  and there are no
pending or, to the best of PNFP's knowledge,  threatened, legal, administrative,
arbitral or other  proceedings,  claims,  actions or  governmental or regulatory
investigations  of any  nature  against  PNFP  or any  of  its  Subsidiaries  or
challenging the validity or propriety of the  transactions  contemplated by this
Agreement as to which, in any such case, there is a reasonable probability of an

                                       12



adverse  determination  and which, if adversely  determined,  will be reasonably
likely to, either  individually  or in the  aggregate,  have a Material  Adverse
Effect on PNFP.

     (b)  There  is  no  injunction,  order,  judgment,  decree,  or  regulatory
restriction  (other than those that apply to  similarly  situated  bank  holding
companies or banks) imposed upon PNFP, any of its  Subsidiaries or the assets of
PNFP or any of its Subsidiaries that has had, or will have, either  individually
or in the aggregate, a Material Adverse Effect on PNFP.

     3.10 Taxes and Tax Returns.

     (a) Each of PNFP and its  Subsidiaries  has duly filed all federal,  state,
foreign and local information returns and Tax returns required to be filed by it
on or prior to the date of this  Agreement  (all such returns being accurate and
complete in all material  respects) and has duly paid or made  provision for the
payment  of all Taxes  that have been  incurred  or are due or claimed to be due
from it by federal,  state,  foreign or local taxing  authorities other than (i)
Taxes or other  governmental  charges that are not yet  delinquent  or are being
contested  in good  faith or have  not been  finally  determined  and have  been
adequately reserved against under GAAP, or (ii) information returns, Tax returns
or Taxes as to which  the  failure  to file,  pay or make  provision  for is not
reasonably likely to have, either  individually or in the aggregate,  a Material
Adverse  Effect  on  PNFP.  The  federal  income  Tax  returns  of PNFP  and its
Subsidiaries  to the knowledge of PNFP have not been examined by the IRS.  There
are no material disputes pending,  or to the knowledge of PNFP, claims asserted,
for Taxes or  assessments  upon PNFP or any of its  Subsidiaries  for which PNFP
does not have reserves that are adequate under GAAP. Neither PNFP nor any of its
Subsidiaries  is a party  to or is  bound  by any  Tax  sharing,  allocation  or
indemnification  agreement  or  arrangement  (other  than such an  agreement  or
arrangement exclusively between or among PNFP and its Subsidiaries).  Within the
past  five  years,  neither  PNFP  nor  any  of  its  Subsidiaries  has  been  a
"distributing  corporation"  or a  "controlled  corporation"  in a  distribution
intended to qualify under Section 355(a) of the Code.

     (b) As used in this  Agreement,  the term  "Tax" or  "Taxes"  means (i) all
federal, state, local, and foreign income, excise, gross receipts, gross income,
ad valorem,  profits,  gains, property,  capital, sales, transfer, use, payroll,
employment,  severance,  withholding,  duties,  intangibles,  franchise,  backup
withholding,  and other taxes, charges, levies or like assessments together with
all penalties  and additions to tax and interest  thereon and (ii) any liability
for Taxes described in clause (i) under Treasury Regulation Section 1.1502-6 (or
any similar provision of state, local or foreign law).

     3.11 Employees.

     (a) Section 3.11(a) of the PNFP  Disclosure  Schedule sets forth a true and
complete list of each material  benefit or  compensation  plan,  arrangement  or
agreement, and any material bonus, incentive,  deferred compensation,  vacation,
stock purchase, stock option, severance, employment, change of control or fringe
benefit plan,  program or agreement that is maintained,  or contributed  to, for
the  benefit  of  current  or  former  directors  or  employees  of PNFP and its
Subsidiaries or with respect to which PNFP or its Subsidiaries  may, directly or
indirectly, have any liability to such directors or employees, as of the date of
this Agreement (the "PNFP Benefit Plans").

                                       13



     (b) PNFP has heretofore  made available to CAVB true and complete copies of
each of the PNFP Benefit Plans and certain related documents, including, but not
limited to, (i) the actuarial  report for such PNFP Benefit Plan (if applicable)
for each of the last two years,  and (ii) the most recent  determination  letter
from the IRS (if applicable) for such PNFP Benefit Plan..

     (c) Except as would not reasonably be expected to have, either individually
or in the  aggregate,  a Material  Adverse  Effect on PNFP, (i) each of the PNFP
Benefit Plans has been  operated and  administered  in all material  respects in
compliance with the Employee  Retirement Income Security Act of 1974, as amended
("ERISA")  and the Code,  (ii) each of the PNFP  Benefit  Plans  intended  to be
"qualified"  within the meaning of Section 401(a) of the Code and has received a
favorable  determination  from  the  IRS  that  such  PNFP  Benefit  Plan  is so
qualified,  and to the knowledge of PNFP, there are no existing circumstances or
any events that have occurred that will adversely affect the qualified status of
any such PNFP Benefit  Plan,  (iii) with respect to each PNFP Benefit Plan which
is subject to Title IV of ERISA,  the present  value of accrued  benefits  under
such PNFP Benefit Plan,  based upon the actuarial  assumptions  used for funding
purposes  in the most recent  actuarial  report  prepared  by such PNFP  Benefit
Plan's actuary with respect to such PNFP Benefit Plan, did not, as of its latest
valuation date, exceed the then current value of the assets of such PNFP Benefit
Plan  allocable to such  accrued  benefits,  (iv) no PNFP Benefit Plan  provides
benefits,  including,  without limitation, death or medical benefits (whether or
not insured),  with respect to current or former  employees or directors of PNFP
or its  Subsidiaries  beyond their  retirement or other  termination of service,
other than (A)  coverage  mandated  by  applicable  law,  (B) death  benefits or
retirement  benefits under any "employee  pension plan" (as such term is defined
in  Section  3(2) of  ERISA),  (C)  deferred  compensation  benefits  accrued as
liabilities  on the books of PNFP or its  Subsidiaries  or (D) benefits the full
cost of which is borne by the current or former  employee  or  director  (or his
beneficiary),  (v) no  material  liability  under  Title  IV of  ERISA  has been
incurred by PNFP,  its  Subsidiaries  or any trade or  business,  whether or not
incorporated,  all of  which  together  with  PNFP,  would be  deemed a  "single
employer"  under Section 4001 of ERISA (a "PNFP ERISA  Affiliate")  that has not
been satisfied in full, and no condition exists that presents a material risk to
PNFP,  its  Subsidiaries  or any PNFP ERISA  Affiliate  of  incurring a material
liability  thereunder,  (vi) no PNFP  Benefit Plan is a  "multiemployer  pension
plan"  (as  such  term  is  defined  in  Section  3(37)  of  ERISA),  (vii)  all
contributions  payable by PNFP or its Subsidiaries as of the Effective Time with
respect to each PNFP Benefit Plan in respect of current or prior plan years have
been  paid or  accrued  in  accordance  with  GAAP,  (viii)  none of  PNFP,  its
Subsidiaries  or any other  person,  including any  fiduciary,  has engaged in a
transaction in connection with which PNFP, its  Subsidiaries or any PNFP Benefit
Plan will be subject to either a material  civil  penalty  assessed  pursuant to
Section  409 or 502(i) of ERISA or a material  Tax  imposed  pursuant to Section
4975  or 4976 of the  Code,  and  (ix) to the  knowledge  of PNFP  there  are no
pending,  threatened  or  anticipated  claims  (other  than  routine  claims for
benefits)  by, on  behalf of or  against  any of the PNFP  Benefit  Plans or any
trusts related thereto.

     (d)  Neither  the  execution  and  delivery  of  this   Agreement  nor  the
consummation of the  transactions  contemplated  hereby will (either alone or in
conjunction  with  any  other  event)  (i)  result  (either  alone  or upon  the
occurrence of any additional acts or events) in any payment (including,  without
limitation,  severance,  unemployment  compensation,  "excess parachute payment"
(within the meaning of Section 280G of the Code), forgiveness of indebtedness or
otherwise)  becoming  due to any  director or any employee of PNFP or any of its

                                       14



affiliates  from PNFP or any of its  affiliates  under any PNFP  Benefit Plan or
otherwise,  (ii) increase any benefits  otherwise payable under any PNFP Benefit
Plan or (iii)  result in any  acceleration  of the time of payment or vesting of
any such benefits that will,  either  individually  or in the aggregate,  have a
Material Adverse Effect on PNFP.

     3.12 SEC Reports.  PNFP has  previously  made available to CAVB an accurate
and complete copy of each (a) final registration statement,  prospectus, report,
schedule and definitive proxy statement filed since January 1, 2000 by PNFP with
the SEC pursuant to the Securities  Act or the Securities  Exchange Act of 1934,
as  amended  (the  "Exchange  Act"),  and  prior  to the  date  hereof  and  (b)
communication mailed by PNFP to its shareholders since January 1, 2000. PNFP has
filed  all  required  reports,  schedules,  registration  statements  and  other
documents with the SEC since January 1, 2000 (the "PNFP  Reports").  As of their
respective  dates of filing  with the SEC (or,  if  amended or  superseded  by a
filing  prior  to the date  hereof,  as of the  date of such  filing),  the PNFP
Reports  complied  in  all  material  respects  with  the  requirements  of  the
Securities  Act or the  Exchange  Act,  as the case may be,  and the  rules  and
regulations of the SEC thereunder  applicable to such PNFP Reports,  and none of
the PNFP Reports when filed contained any untrue statement of a material fact or
omitted to state a material fact  required to be stated  therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

     3.13 Compliance with Applicable Law.

     (a)  PNFP  and  each  of  its  Subsidiaries  hold  all  material  licenses,
franchises,  permits,  patents,  trademarks and authorizations necessary for the
lawful conduct of their  respective  businesses  under and pursuant to each, and
have  complied  in all  material  respects  with and are not in  default  in any
material respect under any,  applicable law, statute,  order, rule,  regulation,
policy,  agreement and/or guideline of any Governmental  Entity relating to PNFP
or any of its  Subsidiaries,  except  where the  failure  to hold such  license,
franchise,  permit or authorization  or such  noncompliance or default will not,
either individually or in the aggregate, have a Material Adverse Effect on PNFP.

     (b) Except as will not have,  either  individually  or in the aggregate,  a
Material Adverse Effect on PNFP, PNFP and each of its Subsidiaries have properly
administered all accounts for which it acts as a fiduciary,  including  accounts
for which it serves as a trustee,  agent,  custodian,  personal  representative,
guardian, conservator or investment advisor, in accordance with the terms of the
governing documents,  applicable state and federal law and regulation and common
law. None of PNFP, any of its Subsidiaries, or any director, officer or employee
of PNFP or of any of its  Subsidiaries,  has  committed any breach of trust with
respect to any such fiduciary  account that will have a Material  Adverse Effect
on PNFP,  and the  accountings  for each  such  fiduciary  account  are true and
correct in all  material  respects  and  accurately  reflect  the assets of such
fiduciary account.

     3.14 Certain Contracts.

     (a) Except as disclosed in Section 3.11(a) of the PNFP Disclosure Schedule,
neither PNFP nor any of its Subsidiaries is a party to or bound by any contract,
arrangement,  commitment  or  understanding  (whether  written or oral) (i) with
respect to the employment of any directors,  officers or employees other than in

                                       15



the ordinary course of business consistent with past practice,  (ii) which, upon
the  consummation or shareholder  approval of the  transactions  contemplated by
this Agreement will (either alone or upon the occurrence of any additional  acts
or  events)  result in any  payment  (whether  of  severance  pay or  otherwise)
becoming  due  from  PNFP,  CAVB,  the  Surviving  Corporation,  or any of their
respective  Subsidiaries  to any officer or employee  thereof,  (iii) which is a
"material  contract"  (as such term is defined in Item  601(b)(10) of Regulation
S-K of the SEC) to be performed  after the date of this  Agreement  that has not
been  filed or  incorporated  by  reference  in the  PNFP  Reports,  (iv)  which
materially  restricts  the  conduct  of any  line  of  business  by PNFP or upon
consummation of the Merger will materially restrict the ability of the Surviving
Corporation  to engage in any line of business in which a bank  holding  company
may  lawfully  engage,  (v) with or to a labor  union or  guild  (including  any
collective bargaining agreement) or (vi) (including any stock option plan, stock
appreciation  rights plan,  restricted stock plan or stock purchase plan) any of
the benefits of which will be increased, or the vesting of the benefits of which
will be  accelerated,  by the  occurrence  of any  shareholder  approval  or the
consummation of any of the transactions  contemplated by this Agreement,  or the
value of any of the benefits of which will be  calculated on the basis of any of
the  transactions  contemplated by this Agreement.  Each contract,  arrangement,
commitment  or  understanding  of the type  described in this  Section  3.14(a),
whether or not set forth in the PNFP Disclosure Schedule,  is referred to herein
as a "PNFP Contract",  and neither PNFP nor any of its Subsidiaries knows of, or
has received  notice of, any  violation of the above by any of the other parties
thereto which will have,  individually or in the aggregate,  a Material  Adverse
Effect on PNFP.

     (b) (i) Each  PNFP  Contract  is valid  and  binding  on PNFP or any of its
Subsidiaries, as applicable, and in full force and effect, (ii) PNFP and each of
its Subsidiaries has in all material respects performed all obligations required
to be  performed  by it to date  under  each PNFP  Contract,  except  where such
noncompliance, either individually or in the aggregate, will not have a Material
Adverse Effect on PNFP, and (iii) no event or condition exists which constitutes
or, after notice or lapse of time or both, will  constitute,  a material default
on the part of PNFP or any of its  Subsidiaries  under any such  PNFP  Contract,
except where such default which will,  either  individually or in the aggregate,
have a Material Adverse Effect on PNFP.

     3.15  Agreements  with  Regulatory  Agencies.  Neither  PNFP nor any of its
Subsidiaries is subject to any  cease-and-desist or other order issued by, or is
a  party  to  any  written   agreement,   consent  agreement  or  memorandum  of
understanding  with,  or  is  a  party  to  any  commitment  letter  or  similar
undertaking  to, or is subject to any order or  directive  by, or has been since
January 1, 2000, a recipient of any supervisory letter from, or since January 1,
2000, has adopted any board resolutions at the request of, any Regulatory Agency
or other  Governmental  Entity that currently  restricts in any material respect
the conduct of its business, would restrict the consummation of the transactions
contemplated  by this  Agreement,  or that in any material manner relates to its
capital  adequacy,  its credit  policies,  its management or its business (each,
whether or not set forth in the PNFP  Disclosure  Schedule,  a "PNFP  Regulatory
Agreement"),  nor to the  knowledge of PNFP has PNFP or any of its  Subsidiaries
been  advised  since  January  1,  2001,  by  any  Regulatory  Agency  or  other
Governmental  Entity that it is considering  issuing or requesting any such PNFP
Regulatory Agreement.

                                       16




     3.16  Interest  Rate Risk  Management  Instruments.  Except as would not be
reasonably likely to have, either  individually or in the aggregate,  a Material
Adverse  Effect on PNFP,  (a) all interest rate swaps,  caps,  floors and option
agreements and other interest rate risk management arrangements, whether entered
into for the  account of PNFP or for the account of a customer of PNFP or one of
its  Subsidiaries,  were entered into in the ordinary course of business and, to
PNFP's  knowledge,  in accordance with prudent  banking  practice and applicable
rules,   regulations   and  policies  of  any  Regulatory   Authority  and  with
counterparties  believed  to be  financially  responsible  at the time,  and are
legal,  valid  and  binding  obligations  of  PNFP  or one  of its  Subsidiaries
enforceable  in  accordance  with  their  terms  (except  as may be  limited  by
bankruptcy, insolvency, moratorium, reorganization or similar laws affecting the
rights of creditors generally and the availability of equitable  remedies),  and
are in full force and effect;  (b) PNFP and each of its  Subsidiaries  have duly
performed in all material respects all of their material obligations  thereunder
to the extent that such  obligations to perform have accrued;  and (c) to PNFP's
knowledge, there are no material breaches, violations or defaults or allegations
or assertions of such by any party thereunder.

     3.17 Undisclosed  Liabilities.  Except for those liabilities that are fully
reflected or reserved against on the consolidated balance sheet of PNFP included
in the PNFP Form 10-Q and for  liabilities  incurred in the  ordinary  course of
business consistent with past practice since June 30, 2005, neither PNFP nor any
of its Subsidiaries has incurred any liability of any nature whatsoever (whether
absolute,  accrued,  contingent  or otherwise  and whether due or to become due)
that, either individually or in the aggregate,  has had or will have, a Material
Adverse Effect on PNFP.

     3.18 Insurance. PNFP and its Subsidiaries have in effect insurance coverage
with  reputable  insurers  or are  self-insured,  which in respect  of  amounts,
premiums,  types and risks insured,  constitutes  reasonably  adequate  coverage
against all risks insured against by bank holding  companies  comparable in size
and operations to PNFP and its Subsidiaries.

     3.19 Environmental Liability. There are no legal, administrative,  arbitral
or other proceedings,  claims,  actions, causes of action, private environmental
investigations or remediation  activities or governmental  investigations of any
nature seeking to impose, or that could reasonably result in the imposition,  on
PNFP of any liability or obligation arising under common law or under any local,
state or federal  environmental  statute,  regulation  or  ordinance  including,
without limitation, the Comprehensive  Environmental Response,  Compensation and
Liability  Act of 1980, as amended  ("CERCLA"),  pending or, to the knowledge of
PNFP,  threatened  against  PNFP,  which  liability or obligation  will,  either
individually or in the aggregate, have a Material Adverse Effect on PNFP. To the
knowledge of PNFP, there is no reasonable basis for any such proceeding,  claim,
action  or  governmental  investigation  that  would  impose  any  liability  or
obligation that will, individually or in the aggregate,  have a Material Adverse
Effect on PNFP. PNFP is not subject to any agreement,  order, judgment,  decree,
letter or memorandum by or with any court,  governmental  authority,  regulatory
agency or third party  imposing any liability or obligation  with respect to the
foregoing that will have,  either  individually or in the aggregate,  a Material
Adverse Effect on PNFP.

     3.20 State  Takeover  Laws. The Board of Directors of PNFP has approved the
transactions  contemplated by this Agreement for purposes of Sections 48-103-101
through  48-103-505 of the TBCA, if applicable to PNFP, such that the provisions

                                       17




of such  sections  of the TBCA  will not apply to this  Agreement  or any of the
transactions contemplated hereby or thereby.

     3.21 Reorganization. As of the date of this Agreement, PNFP is not aware of
any fact or circumstance that would reasonably be expected to prevent the Merger
from  qualifying as a  "reorganization"  within the meaning of Section 368(a) of
the Code.

     3.22  Information  Supplied.  None  of the  information  supplied  or to be
supplied by PNFP for inclusion or incorporation by reference in (i) the Form S-4
will,  at the time the Form S-4 is filed with the SEC and at the time it becomes
effective under the Securities Act,  contain any untrue  statement of a material
fact or omit to state  any  material  fact  required  to be  stated  therein  or
necessary  to make the  statements  therein not  misleading,  and (ii) the Joint
Proxy Statement will, at the date of mailing to shareholders and at the times of
the meetings of shareholders  to be held in connection with the Merger,  contain
any untrue  statement  of a  material  fact or omit to state any  material  fact
required  to be stated  therein  or  necessary  in order to make the  statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.  The Joint Proxy  Statement  will comply as to form in all  material
respects with the requirements of the Exchange Act and the rules and regulations
of the SEC thereunder, except that no representation or warranty is made by PNFP
with respect to statements made or  incorporated  by reference  therein based on
information  supplied by CAVB for inclusion or incorporation by reference in the
Joint Proxy Statement.

     3.23  Internal  Controls.  The  records,   systems,   controls,   data  and
information of PNFP and its  Subsidiaries are recorded,  stored,  maintained and
operated  under means  (including  any  electronic,  mechanical or  photographic
process, whether computerized or not) that are under the exclusive ownership and
direct control of PNFP or its  Subsidiaries or accountants  (including all means
of access thereto and  therefrom),  except for any  non-exclusive  ownership and
non-direct  control that would not  reasonably  be expected to have a Materially
Adverse Effect on the system of internal  accounting  controls  described in the
following  sentence.  As and to the extent  described in the PNFP Reports  filed
with the SEC prior to the date hereof,  PNFP and its  Subsidiaries  have devised
and  maintain a system of internal  accounting  controls  sufficient  to provide
reasonable  assurances  regarding the reliability of financial reporting and the
preparation  of  financial  statements  in  accordance  with GAAP.  PNFP (i) has
designed disclosure controls and procedures to ensure that material  information
relating to PNFP, including its consolidated Subsidiaries,  is made known to the
management  of PNFP by others  within those  entities,  and (ii) has  disclosed,
based  on its  most  recent  evaluation  prior to the  date  hereof,  to  PNFP's
independent  registered public accounting firm and the audit committee of PNFP's
Board of Directors (x) any significant  deficiencies and material  weaknesses in
the design or operation of internal  control over financial  reporting which are
reasonably  likely to  adversely  affect  PNFP's  ability  to  record,  process,
summarize and report  financial  information  and (y) any fraud,  whether or not
material,  that involves  management  or other  employees who have a significant
role in  PNFP's  internal  control  over  financial  reporting.  PNFP  has  made
available to CAVB a summary of any such  disclosure made by management to PNFP's
auditors and audit  committee  since January 1, 2002. PNFP is in full compliance
with Section 404 of the Sarbanes-Oxley Act of 2002.

                                       18



     3.24 Opinion of PNFP  Financial  Advisor.  PNFP has received the opinion of
its
financial  advisor,  Raymond  James & Associates,  Inc.,  dated the date of this
Agreement, to the effect that the Merger Consideration is fair, from a financial
point of view, to PNFP and the holders of PNFP Common Stock.

                                  ARTICLE IV.
                         REPRESENTATIONS AND WARRANTIES
                                     OF CAVB

     Except as disclosed in (a) the CAVB Reports  (defined below) filed prior to
the date hereof or (b) the disclosure schedule (the "CAVB Disclosure  Schedule")
delivered  by CAVB to PNFP  prior  to the  execution  of this  Agreement  (which
schedule  sets  forth,  among other  things,  items the  disclosure  of which is
necessary or appropriate either in response to an express disclosure requirement
contained   in  a  provision   hereof  or  as  an   exception  to  one  or  more
representations or warranties  contained in this Article IV or to one or more of
CAVB's   covenants   contained   in  Article   V,   provided,   however,   that,
notwithstanding  anything in this Agreement to the contrary, (i) no such item is
required to be set forth in such schedule as an exception to a representation or
warranty  if its  absence  would not  result in the  related  representation  or
warranty  being deemed  untrue or incorrect  under the standard  established  by
Section  9.2,  and (ii) the mere  inclusion  of an item in such  schedule  as an
exception to a representation  or warranty shall not be deemed an admission that
such  item  represents  a  material   exception  or  material  fact,   event  or
circumstance  or that such item has had or would be reasonably  likely to have a
Material Adverse Effect on CAVB), CAVB hereby represents and warrants to PNFP as
follows:

     4.1 Corporate Organization.

     (a) CAVB is a  corporation  duly  organized,  validly  existing and in good
standing under the laws of the State of Tennessee.  CAVB has the corporate power
and authority to own or lease all of its  properties  and assets and to carry on
its business as it is now being conducted,  and is duly licensed or qualified to
do business in each  jurisdiction in which the nature of the business  conducted
by it or the character or location of the  properties and assets owned or leased
by it makes such licensing or qualification necessary,  except where the failure
to be so  licensed  or  qualified  would  not,  either  individually  or in  the
aggregate, have a Material Adverse Effect on CAVB.

     (b) CAVB is a bank holding company  registered  under the BHC Act. True and
complete  copies of Charter  (the  "CAVB  Charter"),  and Bylaws of CAVB,  as in
effect as of the date of this Agreement,  have previously been made available by
CAVB to PNFP.

     (c) Each CAVB  Subsidiary (i) is duly organized and validly  existing under
the laws of its  jurisdiction  of  organization,  (ii) is duly  qualified  to do

     4.5  Reports.  CAVB and each of its  Subsidiaries  have  timely  filed  all
reports, registrations and statements,  together with any amendments required to
be made with respect  thereto,  that they were required to file since January 1,
2000 with the Regulatory Agencies, and all other reports and statements required
to be filed by them since January 1, 2000,  including,  without limitation,  any
report  or  statement  required  to be  filed  pursuant  to the  laws,  rules or
regulations of the United States,  any state, or any Regulatory Agency, and have
paid all fees and  assessments due and payable in connection  therewith,  except
where the failure to file such report,  registration or statement or to pay such
fees and assessments,  either individually or in the aggregate,  will not have a
Material Adverse Effect on CAVB. Except for normal  examinations  conducted by a
Regulatory  Agency  in the  ordinary  course  of the  business  of CAVB  and its
Subsidiaries,  no  Regulatory  Agency has initiated  any  proceeding  or, to the
knowledge of CAVB,  investigation into the business or operations of CAVB or any
of its  Subsidiaries  since January 1, 2000,  except where such  proceedings  or
investigation will not, either individually or in the aggregate, have a Material
Adverse  Effect  on  CAVB.  There  is no  unresolved  violation,  criticism,  or
exception  by any  Regulatory  Agency  with  respect to any report or  statement
relating to any  examinations of CAVB or any of its  Subsidiaries  which, in the
reasonable judgment of CAVB, will, either individually or in the aggregate, have
a Material Adverse Effect on CAVB.

     4.6 Financial  Statements.  CAVB has previously made available to PNFP true

fiscal  years ended  December 31, 2002  through  2004,  inclusive as reported in
CAVB's  Annual  Report on Form 10-K for the fiscal year ended  December 31, 2004
(the "CAVB 10-K"),  filed with the SEC under the Exchange Act and accompanied by
the audit report of Raymond Betts & Bates, PC,  independent  public  accountants
with respect to CAVB, and (ii) the unaudited  consolidated balance sheet of CAVB

statements  of income,  changes in  shareholders'  equity and cash flows for the
three-month  periods then ended, as reported in CAVB's  Quarterly Report on Form
10-Q for the  quarterly  period  ended  June 30,  2005 (the  "CAVB  10-Q").  The
financial  statements  referred to in this  Section 4.6  (including  the related
notes,   where   applicable)   fairly  present  in  all  material  respects  the
consolidated results of operations,  changes in shareholders' equity, cash flows

                                       22



and financial  position of CAVB and its Subsidiaries  for the respective  fiscal
periods or as of the  respective  dates  therein  set  forth,  subject to normal
year-end  audit  adjustments in the case of unaudited  statements;  each of such

material respects with applicable accounting requirements and with the published
rules  and  regulations  of the  SEC  with  respect  thereto;  and  each of such
statements  (including the related notes, where applicable) has been prepared in
all material  respects in accordance with GAAP  consistently  applied during the
periods involved,  except in each case as indicated in such statements or in the
notes thereto. The books and records of CAVB and its Subsidiaries have been, and
are being,  maintained in all material  respects in accordance with GAAP and any
other  applicable  legal and  accounting  requirements  and reflect  only actual
transactions.

     4.7 Broker's Fees.  Except for Hovde  Financial  LLC,  neither CAVB nor any
CAVB Subsidiary nor any of their  respective  officers or directors has employed
any  broker  or  finder  or  incurred  any  liability  for  any  broker's  fees,
commissions  or  finder's  fees  in  connection   with  the  Merger  or  related
transactions contemplated by this Agreement.



     4.8 Absence of Certain Changes or Events.

     4.9 Legal Proceedings.

     (a) Except as disclosed in Section 4.9(a) of the CAVB Disclosure  Schedule,
neither  CAVB nor any of its  Subsidiaries  is a party to any,  and there are no
pending or, to the best of CAVB's knowledge,  threatened legal,  administrative,
arbitral or other  proceedings,  claims,  actions or  governmental or regulatory
investigations  of any  nature  against  CAVB  or any  of  its  Subsidiaries  or
challenging the validity or propriety of the  transactions  contemplated by this
Agreement as to which, in any such case, there is a reasonable probability of an
adverse  determination  and which, if adversely  determined,  will be reasonably
likely to, either  individually  or in the  aggregate,  have a Material  Adverse
Effect on CAVB.

     (b)  There  is  no  injunction,  order,  judgment,  decree,  or  regulatory
restriction  (other than those that apply to  similarly  situated  bank  holding
companies or banks) imposed upon CAVB, any of its  Subsidiaries or the assets of
CAVB or any of its Subsidiaries that has had or will have,  either  individually
or in the aggregate, a Material Adverse Effect on CAVB.

     4.10  Taxes and Tax  Returns.  Each of CAVB and its  Subsidiaries  has duly
filed all federal,  state, foreign and local information returns and Tax returns
required to be filed by it on or prior to the date of this  Agreement  (all such
returns being accurate and complete in all material  respects) and has duly paid
or made  provision  for the payment of all Taxes that have been  incurred or are
due or  claimed to be due from it by  federal,  state,  foreign or local  taxing

                                       23




authorities other than (i) Taxes or other governmental  charges that are not yet
delinquent  or are  being  contested  in good  faith or have  not  been  finally
determined  and have  been  adequately  reserved  against  under  GAAP,  or (ii)
information  returns,  Tax returns or Taxes as to which the failure to file, pay
or make provision for is not reasonably likely to have,  either  individually or
in the  aggregate,  a Material  Adverse  Effect on CAVB.  As of the date of this
Agreement,  the IRS is  examining  the  2003  combined  return  of CAVB  and its
Subsidiaries.  Other  than such  ongoing  examination,  the  federal  income Tax
returns of CAVB and its  Subsidiaries,  to the knowledge of CAVB,  have not been
examined by the IRS. There are no material disputes pending, or to the knowledge
of CAVB,  claims  asserted,  for  Taxes or  assessments  upon CAVB or any of its
Subsidiaries  for which CAVB does not have adequate  reserves.  Neither CAVB nor
any of its Subsidiaries is a party to or is bound by any Tax sharing, allocation
or  indemnification  agreement or  arrangement  (other than such an agreement or
arrangement exclusively between or among CAVB and its Subsidiaries).  Within the
past  five  years,  neither  CAVB  nor  any  of  its  Subsidiaries  has  been  a
"distributing  corporation"  or a  "controlled  corporation"  in a  distribution
intended to qualify under Section 355(a) of the Code.

stock purchase, stock option, severance, employment, change of control or fringe
benefit plan,  program or agreement that is maintained,  or contributed  to, for
the  benefit  of  current  or  former  directors  or  employees  of CAVB and its
Subsidiaries or with respect to which CAVB or its Subsidiaries  may, directly or
indirectly, have any liability to such directors or employees, as of the date of

from the IRS (if applicable) for such CAVB Benefit Plan.

     (c) Except as identified in Section 4.11(a) of the CAVB Disclosure Schedule

the CAVB  Benefit  Plans has been  operated  and  administered  in all  material
respects in  compliance  with ERISA and the Code,  (ii) each of the CAVB Benefit
Plans  intended to be  "qualified"  within the meaning of Section  401(a) of the
Code and has  received  a  favorable  determination  from the IRS that such CAVB
Benefit  Plan is so  qualified,  and to the  knowledge  of  CAVB,  there  are no
existing  circumstances  or any events that have  occurred  that will  adversely
affect the qualified status of any such CAVB Benefit Plan, (iii) with respect to
each CAVB Benefit Plan which is subject to Title IV of ERISA,  the present value
of accrued  benefits  under such CAVB  Benefit  Plan,  based upon the  actuarial
assumptions  used for  funding  purposes  in the most  recent  actuarial  report
prepared by such CAVB Benefit  Plan's  actuary with respect to such CAVB Benefit
Plan, did not, as of its latest valuation date, exceed the then current value of
the assets of such CAVB Benefit Plan allocable to such accrued benefits, (iv) no
CAVB Benefit Plan provides benefits,  including,  without  limitation,  death or

                                       24




medical  benefits  (whether or not  insured),  with respect to current or former
employees or directors of CAVB or its  Subsidiaries  beyond their  retirement or
other  termination  of service,  other than (A) coverage  mandated by applicable
law, (B) death benefits or retirement benefits under any "employee pension plan"
(as such term is defined in Section 3(2) of ERISA),  (C)  deferred  compensation
benefits  accrued as liabilities on the books of CAVB or its Subsidiaries or (D)
benefits  the full cost of which is borne by the  current or former  employee or
director (or his beneficiary), (v) no material liability under Title IV of ERISA
has been incurred by CAVB, its Subsidiaries or any trade or business, whether or
not  incorporated,  all of which  together with CAVB,  would be deemed a "single
employer"  under Section 4001 of ERISA (a "CAVB ERISA  Affiliate")  that has not
been satisfied in full, and no condition exists that presents a material risk to
CAVB,  its  Subsidiaries  or any CAVB ERISA  Affiliate  of  incurring a material
liability  thereunder,  (vi) no CAVB  Benefit Plan is a  "multiemployer  pension
plan"  (as  such  term  is  defined  in  Section  3(37)  of  ERISA),  (vii)  all
contributions  payable by CAVB or its Subsidiaries as of the Effective Time with
respect to each CAVB Benefit Plan in respect of current or prior plan years have
been  paid or  accrued  in  accordance  with  GAAP,  (viii)  none of  CAVB,  its
Subsidiaries  or any other  person,  including any  fiduciary,  has engaged in a
transaction in connection with which CAVB, its  Subsidiaries or any CAVB Benefit
Plan will be subject to either a material  civil  penalty  assessed  pursuant to
Section  409 or 502(i) of ERISA or a material  Tax  imposed  pursuant to Section
4975  or 4976 of the  Code,  and  (ix) to the  knowledge  of CAVB  there  are no
pending,  threatened  or  anticipated  claims  (other  than  routine  claims for
benefits)  by, on  behalf of or  against  any of the CAVB  Benefit  Plans or any
trusts related thereto.

     (d)  Except  as set  forth  in  Schedule  4.11(d)  of the  CAVB  Disclosure
Schedule,  neither  the  execution  and  delivery  of  this  Agreement  nor  the
consummation of the  transactions  contemplated  hereby will (either alone or in
conjunction  with  any  other  event)  (i)  result  (either  alone  or upon  the
occurrence of any additional acts or events) in any payment (including,  without
limitation,  severance,  unemployment  compensation,  "excess parachute payment"
(within the meaning of Section 280G of the Code), forgiveness of indebtedness or
otherwise)  becoming  due to any  director or any employee of CAVB or any of its
affiliates  from CAVB or any of its  affiliates  under any CAVB  Benefit Plan or
otherwise,  (ii) increase any benefits  otherwise payable under any CAVB Benefit
Plan or (iii)  result in any  acceleration  of the time of payment or vesting of
any such benefits that will,  either  individually  or in the aggregate,  have a
Material Adverse Effect on CAVB.

and complete copy of each (a) final registration statement,  prospectus, report,
schedule and definitive proxy statement filed since January 1, 2000 by CAVB with

hereof and (b) communication mailed by CAVB to its shareholders since January 1,
2000. CAVB has filed all required reports,  schedules,  registration  statements
and other documents with the SEC since January 1, 2000 (the "CAVB Reports").  As

by a filing prior to the date hereof,  as of the date of such filing),  the CAVB

Securities  Act or the  Exchange  Act,  as the case may be,  and the  rules  and
regulations of the SEC thereunder  applicable to such CAVB Reports,  and none of
the CAVB Reports when filed contained any untrue statement of a material fact or
omitted to state a material fact  required to be stated  therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

                                       25



     4.13 Compliance with Applicable Law.

     (a)  CAVB  and  each  of  its  Subsidiaries  hold  all  material  licenses,
franchises,  permits,  patents,  trademarks and authorizations necessary for the
lawful conduct of their  respective  businesses  under and pursuant to each, and
have  complied  in all  material  respects  with,  and are not in default in any
material respect under, any applicable law, statute,  order,  rule,  regulation,
policy,  agreement and/or guideline of any Governmental  Entity relating to CAVB
or any of its  Subsidiaries,  except  where the  failure  to hold such  license,
franchise,  permit or authorization  or such  noncompliance or default will not,
either individually or in the aggregate, have a Material Adverse Effect on CAVB.

     (b) Except as will not have,  either  individually  or in the aggregate,  a
Material Adverse Effect on CAVB, CAVB and each of its Subsidiaries have properly
administered all accounts for which it acts as a fiduciary,  including  accounts
for which it serves as a trustee,  agent,  custodian,  personal  representative,
guardian, conservator or investment advisor, in accordance with the terms of the
governing documents,  applicable state and federal law and regulation and common
law. None of CAVB, any of its Subsidiaries, or any director, officer or employee
of CAVB or of any of its  Subsidiaries,  has  committed any breach of trust with
respect to any such fiduciary  account that will have a Material  Adverse Effect
on CAVB,  and the  accountings  for each  such  fiduciary  account  are true and
correct in all  material  respects  and  accurately  reflect  the assets of such
fiduciary account.

     4.14 Certain Contracts.

     (a) Except as disclosed in Section 4.11(a) of the CAVB Disclosure Schedule,
neither CAVB nor any of its Subsidiaries is a party to or bound by any contract,
arrangement,  commitment  or  understanding  (whether  written or oral) (i) with
respect to the employment of any directors,  officers or employees other than in
the ordinary course of business consistent with past practice,  (ii) which, upon
the  consummation or shareholder  approval of the  transactions  contemplated by
this Agreement will (either alone or upon the occurrence of any additional  acts
or  events)  result in any  payment  (whether  of  severance  pay or  otherwise)
becoming  due  from  CAVB,  PNFP,  the  Surviving  Corporation,  or any of their
respective  Subsidiaries  to any officer or employee  thereof,  (iii) which is a
"material  contract"  (as such term is defined in Item  601(b)(10) of Regulation
S-K of the SEC) to be performed  after the date of this  Agreement  that has not
been  filed or  incorporated  by  reference  in the  CAVB  Reports,  (iv)  which
materially  restricts  the  conduct  of any  line  of  business  by CAVB or upon

may  lawfully  engage,  (v) with or to a labor  union or  guild  (including  any
collective bargaining agreement) or (vi) (including any stock option plan, stock
appreciation  rights plan,  restricted stock plan or stock purchase plan) any of
the benefits of which will be increased, or the vesting of the benefits of which
will be  accelerated,  by the  occurrence  of any  shareholder  approval  or the
consummation of any of the transactions  contemplated by this Agreement,  or the
value of any of the benefits of which will be  calculated on the basis of any of
the  transactions  contemplated  by this  Agreement.  CAVB has  previously  made
available  to PNFP  true and  correct  copies  of all  employment  and  deferred
compensation  agreements which are in writing and to which CAVB is a party. Each
contract, arrangement, commitment or understanding of the type described in this
Section 4.14(a),  whether or not set forth in the CAVB Disclosure  Schedule,  is

                                       26



referred  to  herein  as a "CAVB  Contract",  and  neither  CAVB  nor any of its
Subsidiaries  knows of, or has received notice of, any violation of the above by
any of the  other  parties  thereto  which  will  have,  individually  or in the
aggregate, a Material Adverse Effect on CAVB.

     (b) (i) Each  CAVB  Contract  is valid  and  binding  on CAVB or any of its
Subsidiaries, as applicable, and in full force and effect, (ii) CAVB and each of
its Subsidiaries has in all material respects performed all obligations required
to be  performed  by it to date  under  each CAVB  Contract,  except  where such
noncompliance, either individually or in the aggregate, will not have a Material
Adverse Effect on CAVB, and (iii) no event or condition exists which constitutes
or, after notice or lapse of time or both, will  constitute,  a material default
on the part of CAVB or any of its  Subsidiaries  under any such  CAVB  Contract,
except where such default which will,  either  individually or in the aggregate,
have a Material Adverse Effect on CAVB.

     4.15  Agreements  with  Regulatory  Agencies.  Neither  CAVB nor any of its
Subsidiaries is subject to any  cease-and-desist or other order issued by, or is
a  party  to  any  written   agreement,   consent  agreement  or  memorandum  of
understanding  with,  or  is  a  party  to  any  commitment  letter  or  similar
undertaking  to, or is subject to any order or  directive  by, or has been since
January 1, 2000, a recipient of any supervisory letter from, or since January 1,
2000, has adopted any board  resolutions at the request of any Regulatory Agency
or other  Governmental  Entity that currently  restricts in any material respect
the conduct of its business, would restrict the consummation of the transactions
contemplated  by this  Agreement or that in any material  manner  relates to its
capital  adequacy,  its credit  policies,  its management or its business (each,
whether or not set forth in the CAVB  Disclosure  Schedule,  a "CAVB  Regulatory
Agreement"),  nor, to the knowledge of CAVB, has CAVB or any of its Subsidiaries
been  advised  since  January  1,  2000,  by  any  Regulatory  Agency  or  other
Governmental  Entity that it is considering  issuing or requesting any such CAVB
Regulatory Agreement.

     4.16  Interest  Rate Risk  Management  Instruments.  Except as would not be
reasonably likely to have, either  individually or in the aggregate,  a Material
Adverse  Effect on CAVB,  (a) all interest rate swaps,  caps,  floors and option
agreements and other interest rate risk management arrangements, whether entered
into for the account of CAVB, one of its  Subsidiaries,  or for the account of a
customer of CAVB or one of its  Subsidiaries,  were entered into in the ordinary
course of business and, to CAVB's knowledge,  in accordance with prudent banking
practice  and  applicable  rules,  regulations  and  policies of any  Regulatory
Authority and with counterparties  believed to be financially responsible at the
time,  and  are  legal,  valid  and  binding  obligations  of CAVB or one of its
Subsidiaries  enforceable  in  accordance  with  their  terms  (except as may be
limited by bankruptcy,  insolvency,  moratorium,  reorganization or similar laws
affecting the rights of creditors  generally and the  availability  of equitable
remedies),  and  are in  full  force  and  effect;  (b)  CAVB  and  each  of its
Subsidiaries  have duly performed in all material respects all of their material
obligations  thereunder  to the extent  that such  obligations  to perform  have
accrued; and (c) to CAVB's knowledge, there are no material breaches, violations
or defaults or allegations or assertions of such by any party thereunder.

     4.17 Undisclosed  Liabilities.  Except for those liabilities that are fully
reflected or reserved against on the consolidated balance sheet of CAVB included
in the CAVB Form 10-Q and for  liabilities  incurred in the  ordinary  course of

                                       27



business consistent with past practice since June 30, 2005, neither CAVB nor any
of its Subsidiaries has incurred any liability of any nature whatsoever (whether
absolute,  accrued,  contingent  or otherwise  and whether due or to become due)
that, either individually or in the aggregate,  has had or will have, a Material
Adverse Effect on CAVB.

     4.18 Insurance. CAVB and its Subsidiaries have in effect insurance coverage
with  reputable  insurers  or are  self-insured,  which in respect  of  amounts,
premiums,  types and risks insured,  constitutes  reasonably  adequate  coverage
against all risks  customarily  insured  against by bank holding  companies  and
their   subsidiaries   comparable  in  size  and  operations  to  CAVB  and  its
Subsidiaries.

     4.19 Environmental Liability. There are no legal, administrative,  arbitral
or other proceedings,  claims,  actions, causes of action, private environmental
investigations or remediation  activities or governmental  investigations of any
nature seeking to impose, or that could reasonably result in the imposition,  on
CAVB of any liability or obligation arising under common law or under any local,
state or federal  environmental  statute,  regulation  or  ordinance  including,
without  limitation,  CERCLA,  pending or, to the knowledge of CAVB,  threatened
against CAVB, which liability or obligation will, either  individually or in the
aggregate,  have a Material  Adverse  Effect on CAVB.  To the knowledge of CAVB,
there  is no  reasonable  basis  for  any  such  proceeding,  claim,  action  or
governmental  investigation  that would impose any liability or obligation  that
will, either individually or in the aggregate, have a Material Adverse Effect on
CAVB. CAVB is not subject to any agreement,  order, judgment,  decree, letter or
memorandum by or with any court,  governmental  authority,  regulatory agency or
third party  imposing any liability or obligation  with respect to the foregoing
that will have,  either  individually  or in the aggregate,  a Material  Adverse
Effect on CAVB.

     4.20 State  Takeover  Laws. The Board of Directors of CAVB has approved the
transactions  contemplated by this Agreement for purposes of Sections 48-103-101
through  48-103-505 of the TBCA, if applicable to CAVB, such that the provisions
of such  sections  of the TCBA  will not apply to this  Agreement  or any of the
transactions contemplated hereby or thereby.

     4.21 Reorganization. As of the date of this Agreement, CAVB is not aware of
any fact or circumstance that would reasonably be expected to prevent the Merger
from  qualifying as a  "reorganization"  within the meaning of Section 368(a) of
the Code.

     4.22  Information  Supplied.  None  of the  information  supplied  or to be
supplied by CAVB for inclusion or incorporation by reference in (i) the Form S-4
will,  at the time the Form S-4 is filed with the SEC and at the time it becomes
effective under the Securities Act,  contain any untrue  statement of a material
fact or omit to state  any  material  fact  required  to be  stated  therein  or
necessary  to make the  statements  therein not  misleading,  and (ii) the Joint
Proxy Statement will, at the date of mailing to shareholders and at the times of
the meetings of shareholders  to be held in connection with the Merger,  contain
any untrue  statement  of a  material  fact or omit to state any  material  fact
required  to be stated  therein  or  necessary  in order to make the  statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.  The Joint Proxy  Statement  will comply as to form in all  material
respects with the requirements of the Exchange Act and the rules and regulations
of the SEC thereunder, except that no representation or warranty is made by CAVB

                                       28



with respect to statements made or  incorporated  by reference  therein based on
information  supplied by PNFP for inclusion or incorporation by reference in the
Joint Proxy Statement.

     4.23  Internal  Controls.  The  records,   systems,   controls,   data  and
information of CAVB and its  Subsidiaries are recorded,  stored,  maintained and
operated  under means  (including  any  electronic,  mechanical or  photographic
process, whether computerized or not) that are under the exclusive ownership and
direct control of CAVB or its  Subsidiaries or accountants  (including all means
of access thereto and  therefrom),  except for any  non-exclusive  ownership and
non-direct  control that would not  reasonably  be expected to have a Materially
Adverse Effect on the system of internal  accounting  controls  described in the
following  sentence.  As and to the extent  described in the CAVB Reports  filed
with the SEC prior to the date hereof,  CAVB and its  Subsidiaries  have devised
and  maintain a system of internal  accounting  controls  sufficient  to provide
reasonable  assurances  regarding the reliability of financial reporting and the
preparation  of  financial  statements  in  accordance  with GAAP.  CAVB (i) has
designed disclosure controls and procedures to ensure that material  information
relating to CAVB, including its consolidated Subsidiaries,  is made known to the
management  of CAVB by others  within those  entities,  and (ii) has  disclosed,
based  on its  most  recent  evaluation  prior to the  date  hereof,  to  CAVB's
independent  registered public accounting firm and the audit committee of CAVB's
Board of Directors (x) any significant  deficiencies and material  weaknesses in
the design or operation of internal  control over financial  reporting which are
reasonably  likely to  adversely  affect  CAVB's  ability  to  record,  process,
summarize and report  financial  information  and (y) any fraud,  whether or not
material,  that involves  management  or other  employees who have a significant
role in  CAVB's  internal  control  over  financial  reporting..  CAVB  has made
available to PNFP a summary of any such  disclosure made by management to PNFP's
auditors and audit  committee  since  January 1, 2002.  CAVB has  initiated  its
process of  compliance  with Section 404 of the  Sarbanes-Oxley  Act of 2002 and
expects to be in full compliance therewith by the mandated compliance date.

     4.24 Opinion of CAVB  Financial  Advisor.  CAVB has received the opinion of
its financial advisor, Hovde Financial LLC dated the date of this Agreement,  to
the effect that the  consideration  received by the holders of CAVB Common Stock
is fair,  from a financial point of view, to CAVB and the holders of CAVB Common
Stock.

                              ADDITIONAL AGREEMENTS

     6.1 Regulatory Matters.

     (a) CAVB and PNFP shall  promptly  prepare  and file with the SEC the Joint
Proxy  Statement and PNFP shall promptly  prepare and file with the SEC the Form
S-4, in which the Joint Proxy  Statement will be included as a prospectus.  Each
of CAVB and PNFP shall use their  reasonable best efforts in  consultation  with
their respective legal counsel to have the Form S-4 declared effective under the
Securities Act as promptly as practicable  after such filing,  and CAVB and PNFP
shall  thereafter mail or deliver the Joint Proxy Statement to their  respective
shareholders.  PNFP shall  also use its  reasonable  best  efforts to obtain all
necessary state  securities law or "Blue Sky" permits and approvals  required to
carry  out the  transactions  contemplated  by this  Agreement,  and CAVB  shall
furnish all information concerning CAVB and the holders of CAVB Capital Stock as
may be reasonably  requested in connection with any such action.  If at any time
prior to or after the Effective Time any  information  relating to either of the
parties,  or their  respective  affiliates,  officers  or  directors,  should be
discovered  by  either  party  which  should  be set  forth in an  amendment  or
supplement  to any of the Form S-4 or the Joint  Proxy  Statement/Prospectus  so
that such  documents  would not include any  misstatement  of a material fact or
omit to state any material fact  necessary to make the  statements  therein,  in
light of the circumstances under which they were made, not misleading, the party
which  discovers such  information  shall promptly notify the other party hereto

                                       33



and,  to the  extent  required  by law,  rules or  regulations,  an  appropriate
amendment or supplement describing such information shall be promptly filed with
the SEC and disseminated to the shareholders of PNFP and CAVB.

     (b) The  parties  hereto  shall  cooperate  with  each  other and use their
reasonable best efforts to promptly prepare and file all necessary documentation
to  effect  all  applications,  notices,  petitions  and  filings,  to obtain as
promptly as practicable all permits,  consents,  approvals and authorizations of
all third parties and Governmental  Entities which are necessary or advisable to
consummate the transactions  contemplated by this Agreement (including,  without
limitation, the Merger), and to comply with the terms and conditions of all such
permits,  consents,  approvals  and  authorizations  of  all  such  Governmental
Entities.  CAVB and PNFP shall have the right to review in advance,  and, to the
extent  practicable,  each will  consult  the other on, in each case  subject to
applicable  laws relating to the exchange of  information,  all the  information
relating  to PNFP or  CAVB,  as the case  may be,  and any of  their  respective
Subsidiaries,  which  appear in any  filing  made  with,  or  written  materials
submitted to, any third party or any Governmental  Entity in connection with the
transactions  contemplated by this Agreement. In exercising the foregoing right,
each of the parties hereto shall act reasonably and as promptly as  practicable.
The parties  hereto agree that they will consult with each other with respect to
the  obtaining of all permits,  consents,  approvals and  authorizations  of all
third parties and Governmental Entities necessary or advisable to consummate the
transactions  contemplated  by this Agreement and each party will keep the other
apprised of the status of matters  relating to  completion  of the  transactions
contemplated herein.

     (c) Each of CAVB and PNFP  shall,  upon  request,  furnish to the other all
information  concerning  itself,  its  Subsidiaries,   directors,  officers  and
shareholders and such other matters as may be reasonably  necessary or advisable
in  connection  with the  Joint  Proxy  Statement,  the  Form  S-4 or any  other
statement,  filing,  notice or application made by or on behalf of CAVB, PNFP or
any of their respective  Subsidiaries to any  Governmental  Entity in connection
with the Merger and the other transactions contemplated by this Agreement.

     (d) Each of CAVB and PNFP shall  promptly  advise the other upon  receiving
any  communication  from any  Governmental  Entity whose  consent or approval is
required for  consummation  of the  transactions  contemplated by this Agreement
that causes such party to believe that there is a reasonable likelihood that any
Requisite  Regulatory  Approval (as defined  below) will not be obtained or that
the receipt of any such approval will be materially delayed.

     (e) PNFP and CAVB shall promptly  furnish each other with copies of written
communications  received  by PNFP and CAVB,  as the case may be, or any of their
respective  Subsidiaries  from,  or  delivered by any of the  foregoing  to, any
Governmental  Entity  in  respect  of  the  transactions  contemplated  by  this
Agreement.

     6.2 Access to Information.

     (a) Upon  reasonable  notice and subject to applicable laws relating to the
exchange of  information,  each of CAVB and PNFP,  for the purposes of verifying

the other matters contemplated by this Agreement, shall, and shall cause each of
their   respective   Subsidiaries   to,  afford  to  the  officers,   employees,

Subsidiaries  to, make  available  to the other party (i) a copy of each report,
schedule,  registration  statement  and other  document  filed or received by it
during such period pursuant to the  requirements  of federal  securities laws or
federal or state  banking laws (other than  reports or  documents  which CAVB or
PNFP, as the case may be, is not permitted to disclose under applicable law) and
(ii) all other information concerning its business,  properties and personnel as
such  party  may  reasonably  request.  Neither  CAVB  nor PNFP nor any of their
respective  Subsidiaries  shall be required to provide  access to or to disclose
information  where such access or  disclosure  would  violate or  prejudice  the
rights  of CAVB's  or  PNFP's,  as the case may be,  customers,  jeopardize  the
attorney-client  privilege of the  institution  in possession or control of such
information or contravene any law, rule, regulation,  order,  judgment,  decree,
fiduciary  duty or  binding  agreement  entered  into  prior to the date of this
Agreement.  The  parties  hereto  will make  appropriate  substitute  disclosure
arrangements  under  circumstances  in which the  restrictions  of the preceding
sentence apply.

     (b) Each of PNFP and CAVB  agrees  that it will  not,  and will  cause  its
representatives  not to, use any information  obtained  pursuant to this Section
6.2 (as well as any  other  information  obtained  prior to the date  hereof  in
connection with entering into this  Agreement) for any purpose  unrelated to the
consummation of the transactions contemplated by this Agreement.  Subject to the
requirements  of law,  each  party  will keep  confidential,  and will cause its
representative  to keep  confidential,  all information  and documents  obtained
pursuant to this Section 6.2 (as well as any other information obtained prior to
the date hereof in connection with the entering into of this  Agreement)  unless
such information (i) was already known to such party,  (ii) becomes available to
such  party  from  other  sources  not  known  by such  party  to be  bound by a
confidentiality  obligation,  (iii) is disclosed with the prior written approval
of the providing party or (iv) is or becomes readily ascertainable from publicly
available  sources.   If  this  Agreement  is  terminated  or  the  transactions
contemplated  by this Agreement  shall  otherwise fail to be  consummated,  each
party  shall  promptly  cause  all  copies  of  documents  or  extracts  thereof
containing  information  and data as to the other  party to be  returned  to the
other party.

     (c)  No  investigation  by  either  of  the  parties  or  their  respective
representatives shall affect the representations and warranties of the other set
forth herein.

     6.3 Shareholders' Approvals.  Each of CAVB and PNFP shall call a meeting of
its shareholders to be held as soon as reasonably practicable for the purpose of
voting upon proposals to adopt this  Agreement and approve the Merger  Agreement
and the Merger,  and each shall use its reasonable  best efforts,  to cause such
meetings to occur as soon as reasonably  practicable  and on the same date.  The
Board of  Directors  of each of PNFP  and CAVB  shall  use its  reasonable  best
efforts (and subject to its fiduciary  duty) to obtain from the  shareholders of
PNFP and CAVB,  as the case may be,  the vote in favor of the  adoption  of this
Agreement  required by the TBCA and PNFP's and CAVB's charter and bylaws, as the
case may be to consummate the transactions contemplated hereby.  Notwithstanding
anything to the contrary herein, unless this Agreement has been terminated, this
Agreement  shall  be  submitted  to the  shareholders  of CAVB  and PNFP at such
meeting  for the  purpose of  obtaining  the CAVB  Shareholder  Approval or PNFP
Shareholder  Approval,  as the case  may be,  and  voting  on the  approval  and

                                       35



adoption of this  Agreement  and  nothing  contained  herein  shall be deemed to
relieve CAVB and PNFP of such obligations.

     6.4 Legal  Conditions  to Merger.  Each of CAVB and PNFP  shall,  and shall
cause its  Subsidiaries  to, use their  reasonable  best efforts (a) to take, or
cause to be taken, all actions necessary, proper or advisable to comply promptly
with  all  legal  requirements  that  may  be  imposed  on  such  party  or  its
Subsidiaries with respect to the Merger and, subject to the conditions set forth
in Article VII hereof,  to  consummate  the  transactions  contemplated  by this
Agreement,  and (b) to obtain (and to cooperate  with the other party to obtain)
any material consent, authorization,  order or approval of, or any exemption by,
any  Governmental  Entity  and any other  third  party  that is  required  to be
obtained by PNFP or CAVB or any of their  respective  Subsidiaries in connection
with the Merger and the other transactions contemplated by this Agreement.

     6.5  Affiliates.  CAVB shall use its reasonable  best efforts to cause each
director, executive officer and other person who is an "affiliate" (for purposes
of Rule 145 under the  Securities  Act) of CAVB to deliver  to PNFP,  as soon as
practicable  after  the  date of this  Agreement,  and  prior to the date of the
shareholders'  meetings  called by CAVB to be held  pursuant  to Section  6.3, a
written agreement, in the form of Exhibit 6.5.

     6.6 Stock Quotation or Listing.  PNFP shall cause the shares of PNFP Common
Stock to be issued in the Merger to be qualified for quotation or listing on the
NASDAQ National  Market,  subject to official  notice of issuance,  prior to the
Effective Time. PNFP shall cause the shares of CAVB Common Stock to be de-listed
with the NASDAQ National Market and the SEC after the Effective Time.

     6.7 Employee Benefit Plans; Existing Agreements.

     (a) As of the Effective Time, to the extent  permissible under the terms of
the PNFP employee benefit Plans, the employees of CAVB and its Subsidiaries (the
"CAVB  Employees")  shall be eligible to participate in PNFP's employee  benefit
plans  in  which  similarly  situated  employees  of  PNFP  or its  Subsidiaries
participate,  to the same extent as similarly  situated employees of PNFP or its
Subsidiaries  (it being  understood  that  inclusion of CAVB Employees in PNFP's
employee  benefit  plans may occur at different  times with respect to different
plans) except as provided below.

     (b) With respect to each PNFP Plan that is an "employee  benefit  plan," as
defined in section 3(3) of ERISA,  for purposes of  determining  eligibility  to
participate,  and entitlement to benefits,  including for severance benefits and
vacation  entitlement,  service with CAVB shall be treated as service with PNFP;
provided,  however, that such service shall not be recognized to the extent that
such  recognition  would result in a duplication  or increase of benefits.  Such
service  also shall  apply for  purposes  of  satisfying  any  waiting  periods,
evidence of  insurability  requirements,  or the  application of any preexisting
condition limitations.  Each PNFP employee benefit plan shall waive pre-existing
condition  limitations  to the same  extent  waived  under the  applicable  CAVB
employee  benefit plan.  CAVB  Employees  shall be given credit for amounts paid
under a  corresponding  benefit  plan  during the same  period for  purposes  of

                                       36




applying  deductibles,  copayments  and  out-of-pocket  maximums  as though such
amounts had been paid in  accordance  with the terms and  conditions of the PNFP
employee benefit plans.

     (c) From and after the Effective Time,  PNFP or the Surviving  Corporation,
as  applicable,   will  assume  and  honor  and  shall  cause  the   appropriate
Subsidiaries  of PNFP to assume and to honor in accordance  with their terms all
employment,  severance,  change of control and other compensation agreements and
arrangements  between CAVB or its Subsidiaries and any employee thereof, and all
accrued and vested benefit obligations, including any related to CAVB's Director
Supplemental Retirement Plan or Executive Supplemental Retirement Plan, existing
prior to the  execution of this  Agreement  which are between CAVB or any of its
Subsidiaries and any current or former director, officer, employee or consultant
thereof. PNFP acknowledges and agrees that the Merger shall constitute a "Change
of Control" or "Change in  Control"  as defined in such  agreements  and further
agrees that any subsequent  voluntary  termination by those employees subject to
severance  agreements  and set forth on  Section  6.7(e) of the CAVB  Disclosure
Schedule of his or her  employment  within  twelve (12) months of the  Effective
Time shall  automatically  obligate  PNFP or the Surviving  Corporation  to make
payment of obligations under any such agreements.

     (d) From and after the Effective Time,  PNFP or the Surviving  Corporation,
as  applicable,  will,  and will  cause any  applicable  Subsidiary  thereof  or
Employee  Benefit Plan, to provide or pay when due to CAVB's employees as of the
Effective Time all benefits and compensation  pursuant to CAVB's Employee Plans,
programs  and  arrangements  in effect  on the date  hereof  earned  or  accrued
through, and to which such individuals are entitled as of the Effective Time (or
such later time as such  Employee  Benefit  Plans as in effect at the  Effective
Time are terminated or canceled by PNFP or the Surviving Corporation) subject to
compliance with the terms of this Agreement,  including, without limitation, any
amounts accrued for the benefit of the employees of the CAVB as of the Effective
Time,  payable pursuant to CAVB's and its Subsidiaries  cash bonus plan based on
return on equity, which amount PNFP agrees to pay within ten (10) days following
the Closing of the Merger.

     6.8 Indemnification; Directors' and Officers' Insurance.

     (a)  In  the  event  of any  threatened  or  actual  claim,  action,  suit,
proceeding  or  investigation,   whether  civil,   criminal  or  administrative,
including,  without  limitation,  any such claim,  action,  suit,  proceeding or
investigation  in which any individual who is now, or has been at any time prior
to the date of this  Agreement,  or who becomes prior to the  Effective  Time, a
director or officer or employee of CAVB or any of its Subsidiaries, or who is or
was  serving at the  request of CAVB or any of its  Subsidiaries  as a director,
officer,  employee or agent of another person, including any entity specified in
the CAVB Disclosure Schedule (the "Indemnified  Parties"),  is, or is threatened
to be, made a party based in whole or in part on, or arising in whole or in part
out of, or pertaining  to (i) the fact that he is or was a director,  officer or
employee of CAVB or any of its  Subsidiaries or any entity specified in the CAVB
Disclosure  Schedule  or any of  their  respective  predecessors  or  (ii)  this
Agreement or any of the transactions  contemplated  hereby,  whether in any case
asserted or arising before or after the Effective Time, the parties hereto agree
to cooperate and use their best efforts to defend  against and respond  thereto.
It is understood and agreed that after the Effective  Time, PNFP shall indemnify
and hold  harmless,  as and to the fullest  extent  permitted by law,  each such
Indemnified  Party  against any losses,  claims,  damages,  liabilities,  costs,

                                       37


expenses  (including  reasonable  attorney's fees and expenses in advance of the
final  disposition  of any claim,  suit,  proceeding  or  investigation  to each
Indemnified  Party to the fullest  extent  permitted  by law upon receipt of any
undertaking  required by applicable law),  judgments,  fines and amounts paid in
settlement in connection with any such threatened or actual claim, action, suit,
proceeding or investigation.

     (b) PNFP shall use its  reasonable  best  efforts to cause the  individuals
serving as  officers  and  directors  of CAVB,  its  Subsidiaries  or any entity
specified in the CAVB  Disclosure  Schedule  immediately  prior to the Effective
Time to be covered for a period of six (6) years from the Effective Time (or the
period of the applicable  statute of  limitations,  if longer) by the directors'
and officers'  liability insurance policy maintained by CAVB (provided that PNFP
may  substitute  therefor  policies  of at least the same  coverage  and amounts
containing  terms  and  conditions  which  are not less  advantageous  than such
policy) with respect to acts or omissions  occurring prior to the Effective Time
which were committed by such officers and directors in their capacity as such.

     (c) In the event PNFP or any of its successors or assigns (i)  consolidates
with or  merges  into any  other  person  and  shall  not be the  continuing  or
surviving  corporation  or  entity  of such  consolidation  or  merger,  or (ii)
transfers or conveys all or  substantially  all of its  properties and assets to
any  person,  then,  and in each such  case,  to the  extent  necessary,  proper
provision  shall be made so that the  successors  and assigns of PNFP assume the
obligations set forth in this Section 6.8.

     (d) The provisions of this Section 6.8 shall survive the Effective Time and
are  intended  to be for the  benefit  of,  and shall be  enforceable  by,  each
Indemnified Party and his or her heirs and representatives.

     6.9  Additional  Agreements.  In case  at any  time  before  or  after  the
Effective  Time any further  action is  necessary  or desirable to carry out the
purposes of this Agreement (including,  without limitation, any merger between a
Subsidiary of PNFP, on the one hand,  and a Subsidiary of CAVB, on the other) or
to vest the Surviving  Corporation  with full title to all  properties,  assets,
rights,  approvals,  immunities  and  franchises  of any of the  parties  to the
Merger,  the proper  officers and directors of each party to this  Agreement and
their  respective  Subsidiaries  shall take all such necessary  action as may be
reasonably  requested  by, and at the sole expense of, PNFP. As long as PNFP has
certified to CAVB that all  conditions  to Closing have been met as described in
this Agreement,  if PNFP makes a request to CAVB to make accounting  adjustments
prior to the Effective  Time, such changes shall be made, but to the extent CAVB
might not have  otherwise made such  adjustments  except at the request of PNFP,
such changes shall not impact the calculation of income or financial returns for
purposes of determining the bonuses of employees of CAVB or its Subsidiaries.

     6.10 Advice of Changes.  CAVB and PNFP shall each promptly advise the other
party of any change or event (i) having a Material  Adverse Effect on it or (ii)
which it believes  would or would be reasonably  likely to cause or constitute a
material  breach  of  any  of  its  representations,  warranties,  covenants  or
agreements contained herein; provided,  however, that no such notification shall
affect the representations,  warranties,  covenants or agreements of the parties
(or remedies with respect  thereto) or the conditions to the  obligations of the
parties  under this  Agreement;  provided  further that a failure to comply with

                                       38



this Section 6.10 shall not constitute the failure of any condition set forth in
Article VII to be satisfied  unless the  underlying  Material  Adverse Effect or
material  breach would  independently  result in the failure of a condition  set
forth in Article VII to be satisfied.

     6.11  Exemption from  Liability  Under Section  16(b).  PNFP and CAVB agree
that,  in order to most  effectively  compensate  and retain CAVB  Insiders  (as
defined  below)  in  connection  with the  Merger,  both  prior to and after the
Effective  Time, it is desirable  that CAVB Insiders not be subject to a risk of
liability  under  Section  16(b)  of the  Exchange  Act to  the  fullest  extent
permitted by applicable law in connection  with the conversion of shares of CAVB
Common  Stock and CAVB Stock  Options  into shares of PNFP  Common  Stock in the
Merger,  and for that compensatory and retentive purpose agree to the provisions
of this  Section  6.11.  Assuming  that CAVB  delivers  to PNFP the  Section  16
Information  (as defined below) in a timely  fashion,  the Board of Directors of
PNFP, or a committee of Non-Employee  Directors thereof (as such term is defined
for purposes of Rule 16b-3(d) under the Exchange Act),  shall adopt a resolution
providing that the receipt by CAVB Insiders of PNFP Common Stock in exchange for
shares of CAVB Common Stock, and of options on PNFP Common Stock upon conversion
of options on CAVB  Common  Stock,  in each case  pursuant  to the  transactions
contemplated  by this Agreement and to the extent such  securities are listed in
the Section 16 Information, are intended to be exempt from liability pursuant to
Section 16(b) under the Exchange Act. The term  "Section 16  Information"  shall
mean information accurate in all material respects regarding CAVB Insiders,  the
number of shares  of CAVB  Common  Stock  held by each  such  CAVB  Insider  and
expected to be exchanged for PNFP Common Stock in the Merger, and the number and
description  of the options on CAVB Common  Stock held by each such CAVB Insider
and  expected to be converted  into  options on PNFP Common Stock in  connection
with the Merger;  provided that the  requirement  for a description  of any CAVB
Stock Options shall be deemed to be satisfied if copies of all CAVB Stock Plans,
and forms of  agreements  evidencing  grants  thereunder,  under which such CAVB
Stock  Options have been  granted,  have been made  available to PNFP.  The term
"CAVB  Insiders" shall mean those officers and directors of CAVB who are subject
to the reporting  requirements  of Section 16(a) of the Exchange Act and who are
listed in the Section 16 Information.

     6.12 Acquisition Proposals.

     (a) CAVB and its  Subsidiaries  and  each of their  respective  affiliates,
directors,  officers,  employees,  agents  and  representatives  (including  any
investment   banker,   financial   advisor,   attorney,   accountant   or  other
representative  retained by CAVB or any of its  Subsidiaries)  shall immediately
cease any discussions or negotiations with any other parties that may be ongoing
with respect to the possibility or consideration of any Acquisition Proposal, as
defined below.  From the date of this Agreement through the Effective Time, CAVB
shall  not,  nor  shall it  permit  any of its  Subsidiaries  to,  nor  shall it
authorize  or permit  any of its or its  Subsidiaries'  directors,  officers  or
employees or any investment banker, financial advisor,  attorney,  accountant or
other  representative  retained by it or any of its Subsidiaries to, directly or
indirectly through another person, (i) solicit, initiate or encourage (including
by way of  furnishing  information  or  assistance),  or take any  other  action
designed to  facilitate or encourage any inquiries or the making of any proposal
that constitutes,  or is reasonably likely to lead to, any Acquisition Proposal,
(ii)  participate in any discussions or  negotiations  regarding any Acquisition

                                       39



Proposal  or  (iii)  make  or  authorize  any   statement,   recommendation   or
solicitation  in support  of any  Acquisition  Proposal.  Any  violation  of the
foregoing  restrictions  by any  representative  of  CAVB,  whether  or not such
representative  is so  authorized  and  whether  or not such  representative  is
purporting to act on behalf of such party or otherwise,  shall be deemed to be a
breach of this Agreement by CAVB.

     (b) (i)Notwithstanding the foregoing,  the Board of Directors of CAVB shall
be  permitted,  prior to its  meeting of  shareholders  to be held  pursuant  to
Section 6.3, to engage in  discussions  and  negotiations  with,  or provide any
nonpublic  information or data to, any person in response to an unsolicited bona
fide  written  Acquisition  Proposal  by such person made after the date of this
Agreement which its Board of Directors concludes in good faith constitutes or is
reasonably  likely to result in a Superior  Proposal,  as defined below,  if and
only to the extent that the Board of Directors of CAVB reasonably  determines in
good faith (after consultation with outside legal counsel) that failure to do so
would cause it to violate its fiduciary  duties under applicable law and subject
to  compliance  with the other terms of this Section 6.12 and to first  entering
into a confidentiality  agreement having provisions that are no less restrictive
to such person than those contained in the Confidentiality Agreement.

     (ii) CAVB shall notify PNFP  promptly (but in no event later than 24 hours)
after  receipt  of any  Acquisition  Proposal,  or  any  request  for  nonpublic
information  relating  to CAVB or any of its  Subsidiaries  by any  person  that
informs CAVB or any of its Subsidiaries  that it is considering  making,  or has
made, an  Acquisition  Proposal,  or any inquiry from any person seeking to have
discussions or negotiations  with such party relating to a possible  Acquisition
Proposal.  Such notice shall be made orally and confirmed in writing,  and shall
indicate the identity of the person making the Acquisition Proposal,  inquiry or
request and the material  terms and  conditions of any  inquiries,  proposals or
offers (including a copy thereof if in writing and any related  documentation or
correspondence).  CAVB shall also  promptly,  and in any event  within 24 hours,
notify  PNFP,  orally  and  in  writing,   if  it  enters  into  discussions  or
negotiations   concerning  any  Acquisition   Proposal  or  provides   nonpublic
information  or data to any person in accordance  with this Section  6.12(b) and
keep  PNFP  informed  of the  status  and terms of any such  proposals,  offers,
discussions or negotiations on a current basis, including by providing a copy of
all material documentation or correspondence relating thereto.

     (iii)  Nothing  contained in this Section 6.14 shall  prohibit  CAVB or its
Subsidiaries  from taking and disclosing to its shareholders a position required
by Rule 14e-2(a) or Rule 14d-9  promulgated  under the Exchange  Act;  provided,
however,  that  compliance  with such rules shall not in any way limit or modify
the effect  that any  action  taken  pursuant  to such rules has under any other
provision of this Agreement.

     (c) CAVB agrees that (i) it will and will cause its  Subsidiaries,  and its
and their officers,  directors,  agents,  representatives and advisors to, cease
immediately  and  terminate  any and all  existing  activities,  discussions  or
negotiations  with any third parties  conducted  heretofore  with respect to any
Acquisition  Proposal,  and (ii) it will not release  any third  party from,  or
waive any provisions of, any confidentiality or standstill agreement to which it
or any of its Subsidiaries is a party with respect to any Acquisition Proposal.

                                       40



     (d) Nothing in this Section  6.12 shall (x) permit CAVB to  terminate  this
Agreement or (y) affect any other obligation of CAVB under this Agreement.  CAVB
shall not submit to the vote of its shareholders any Acquisition  Proposal other
than the Merger.

     (e) For purposes of this Agreement,  the term "Acquisition  Proposal" means
any inquiry,  proposal or offer, filing of any regulatory  application or notice
(whether in draft or final form) or  disclosure of an intention to do any of the
foregoing from any person relating to any (w) direct or indirect  acquisition or
purchase  of a  business  that  constitutes  a  substantial  portion  of the net
revenues,  net income or assets of CAVB or any of its  significant  subsidiaries
(as defined under Regulation S-X of the SEC), (x) direct or indirect acquisition
or purchase of any class of equity  securities  representing  10% or more of the
voting  power  of CAVB or its  significant  subsidiaries,  (y)  tender  offer or
exchange  offer that if  consummated  would  result in any  person  beneficially
owning 10% or more of the voting  power of CAVB,  or (z) merger,  consolidation,
business  combination,  recapitalization,  liquidation,  dissolution  or similar
transaction  involving CAVB or any of its Subsidiaries,  in each case other than
the transactions contemplated by this Agreement.

     (f) For purposes of this Agreement,  "Superior  Proposal" means a bona fide
written  Acquisition  Proposal which the Board of Directors of CAVB concludes in
good faith,  after  consultation with its financial advisors and legal advisors,
taking into account all legal,  financial,  regulatory  and other aspects of the
proposal  and the person  making the  proposal  (including  any  break-up  fees,
expense  reimbursement  provisions and conditions to consummation),  (i) is more
favorable to the  shareholders  of CAVB from a financial point of view, than the
transactions  contemplated  by this  Agreement  and  (ii) is fully  financed  or
reasonably  capable of being fully  financed,  reasonably  likely to receive all
required  governmental  approvals  on a timely  basis and  otherwise  reasonably
capable of being completed on the terms proposed; provided that, for purposes of
this definition of "Superior Proposal," the term Acquisition Proposal shall have
the meaning  assigned to such term in Section  6.12(e) except that the reference
to "10% or more" in the definition of "Acquisition  Proposal" shall be deemed to
be a reference to "a majority" and  "Acquisition  Proposal" shall only be deemed
to refer to a transaction involving CAVB.

     6.13 Bank Merger.  At or prior to the Effective Time, if requested by PNFP,
CAVB shall  cause CAVB BANK to enter into an  Agreement  and Plan of Merger (the
"Bank Merger  Agreement") with PNFP BANK pursuant to which CAVB BANK shall merge
with and into PNFP BANK after the Merger.  Promptly following  execution of such
Bank Merger Agreement, CAVB shall approve such agreement as the sole shareholder
of CAVB BANK. The Bank Merger  Agreement shall contain such terms and conditions
as  are  reasonable,   normal  and  customary  in  light  of  the   transactions
contemplated hereby including a covenant that consummation of the merger of CAVB
BANK with and into PNFP BANK  would not occur  earlier  than  simultaneous  with
consummation  of the Merger and a provision for  termination  of the Bank Merger
Agreement upon termination of this Agreement.

                                       41



                                  ARTICLE VII.

respective  obligations  of the parties to effect the Merger shall be subject to
the satisfaction at or prior to the Effective Time of the following conditions:

of counsel, in form and substance  reasonably  satisfactory to PNFP and CAVB and
their respective  counsel,  dated the Closing Date,  substantially to the effect
that, on the basis of facts,  representations  and assumptions set forth in each
such  opinion  which  are  consistent  with the state of facts  existing  at the
Effective Time:

     (i) The Merger will constitute a reorganization under Section 368(a) of the
Code, and PNFP and CAVB will each be a party to the reorganization;

     (ii) No gain or loss will be  recognized by PNFP or CAVB as a result of the
Merger; and

     (iii)  No gain or loss  will be  recognized  by  shareholders  of CAVB  who

interest in PNFP Common Stock).

                                       42



     In   rendering   such   opinion,   counsel   may   require  and  rely  upon
representations contained in certificates of officers of PNFP, CAVB and others.

                            TERMINATION AND AMENDMENT

     8.1 Termination.  This Agreement may be terminated at any time prior to the
Effective  Time,  whether  before  or  after  approval  of  the  Merger  by  the
shareholders of CAVB or PNFP:

     (a) by  mutual  consent  of PNFP and CAVB in a written  instrument,  if the
Board of Directors of each so  determines by a vote of a majority of the members
of its respective entire Board of Directors;

     (b) by either the Board of  Directors  of PNFP or the Board of Directors of
CAVB, upon written notice to the other party, if a Governmental Entity that must
provide PNFP or CAVB with a Requisite Regulatory Approval has denied approval of
the  Merger  and  such  denial  has  become  final  and  non-appealable;  or any
Governmental Entity of competent jurisdiction shall have issued an order, decree
or ruling  or taken  any other  action  permanently  restraining,  enjoining  or
otherwise prohibiting the Merger, and such order, decree, ruling or other action
has  become  final  and  non-appealable;  provided,  however,  that the right to
terminate this Agreement under this Section 8.1(b) shall not be available to any
party whose failure to comply with any provision of this  Agreement has been the
cause of, or resulted in, such action;

     (c) by either the Board of  Directors  of PNFP or the Board of Directors of
CAVB,  upon written notice to the other party, if the Merger shall not have been
consummated on or before March 31, 2006;  provided,  however,  that the right to
terminate this Agreement under this Section 8.1(c) shall not be available to any
party whose failure to comply with any provision of this  Agreement has been the
cause of, or  resulted  in,  the  failure of the  Effective  Time to occur on or
before such date;

     (d) by either CAVB or PNFP (provided that the party  terminating  shall not
be in  material  breach  of any of its  obligations  under  Section  6.3) if any
approval of the  shareholders  of CAVB or PNFP required for the  consummation of
the Merger shall not have been obtained upon a vote taken thereon at a duly held
meeting of such shareholders or at any adjournment or postponement thereof;

     (e) by either PNFP or CAVB (provided that the terminating party is not then
in material breach of any representation,  warranty, covenant or other agreement
contained   herein)   if  there   shall  have  been  a  breach  of  any  of  the
representations  or warranties  set forth in this  Agreement by the other party,
which breach is not cured within  thirty days  following  written  notice to the
party committing such breach,  or which breach,  by its nature,  cannot be cured
prior to the Closing; provided, however, that neither party shall have the right
to terminate this Agreement pursuant to this Section 8.1(e) unless the breach of
representation or warranty, together with all other such breaches, would entitle
the party  receiving  such  representation  not to consummate  the  transactions
contemplated  hereby  under  Section  7.2(a)  (in  the  case  of a  breach  of a
representation  or warranty by PNFP) or Section  7.3(a) (in the case of a breach
of a representation or warranty by CAVB);

                                       44



     (f) by either PNFP or CAVB (provided that the terminating party is not then
in material breach of any representation,  warranty, covenant or other agreement
contained  herein) if there shall have been a breach of any of the  covenants or
agreements  set forth in this  Agreement on the part of the other  party,  which
breach shall not have been cured  within  thirty days  following  receipt by the
breaching party of written notice of such breach from the other party hereto, or
which  breach,  by its nature,  cannot be cured prior to the Closing;  provided,
however,  that neither  party shall have the right to terminate  this  Agreement
pursuant to this Section 8.1(f) unless the breach of covenant, together with all
other such  breaches,  would  entitle the party  entitled to the benefit of such
covenant not to consummate the  transactions  contemplated  hereby under Section
7.2(b) (in the case of a breach of covenant  by PNFP) or Section  7.3(b) (in the
case of a breach of covenant by CAVB); or

     (g) by either PNFP or CAVB, if (i) the Board of Directors of the other does
not  publicly  recommend  in the Joint  Proxy  Statement  that its  shareholders
approve and adopt this  Agreement,  (ii) after  recommending  in the Joint Proxy
Statement that such shareholders approve and adopt this Agreement, such Board of
Directors shall have withdrawn,  modified or amended such  recommendation in any
manner adverse to the other party, or (iii) the other party materially  breaches
its obligations under this Agreement by reason of a failure to call a meeting of
its  shareholders or a failure to prepare and mail to its shareholders the Joint
Proxy Statement/Prospectus in accordance with Sections 6.1 and 6.3.

     (h) by PNFP, if the Board of Directors of CAVB has authorized, recommended,
proposed or publicly announced its intention to authorize,  recommend or propose
any Acquisition Proposal, as defined below, with any person other than PNFP.

     8.2 Effect of Termination. In the event of termination of this Agreement by
either CAVB or PNFP as provided in Section 8.1, this Agreement  shall  forthwith
become void and there shall be no liability or obligation on the part of PNFP or
CAVB or their respective officers or directors,  except with respect to Sections
6.2(b), which may be enforced by injunction restraining the breaching party from
violation of this provision, the parties hereby consent to such injunction, 8.2,
8.3, 9.4, and 9.10, which shall survive such termination. Liabilities or damages
arising out of the willful breach of this  Agreement  shall be assessed and paid
in the amount of $2.5 million by such breaching party to the other party.

     8.3 Termination Fee.

     (a) As an alternative to the fee specified in Section 8.2, PNFP may request
that CAVB shall pay PNFP, by wire transfer of immediately  available  funds, the
sum of $5.0 million (the  "Termination  Fee") if this Agreement is terminated as
follows:

     (i) if PNFP shall terminate this Agreement pursuant to Section 8.1(h), then
CAVB  shall  pay  the  Termination  Fee  on  the  business  day  following  such
termination;

     (ii) if (A) either party shall terminate this Agreement pursuant to Section
8.1(d)  because  the  required  CAVB  shareholder  approval  shall not have been

                                       45



received and (B) at any time after the date of this  Agreement  and at or before
the date of the CAVB Shareholders  Meeting a bona fide Acquisition  Transaction,
as defined below, shall have been publicly  announced or otherwise  communicated
to the  Board  of  Directors  of CAVB (a  "Public  Proposal")  that has not been
withdrawn  prior to such date,  then CAVB shall pay one-third of the Termination
Fee on the business day  following  such  termination;  and if (C) within twelve
(12) months of the date of such  termination of this  Agreement,  CAVB or any of
its  Subsidiaries  enters  into any  definitive  Agreement  with  respect to, or
consummates,  any  Acquisition  Transaction,  then CAVB shall pay the  remaining
two-thirds of the Termination Fee on the date of such execution or consummation;
and

     (iii) if (A) either  party  shall  terminate  this  Agreement  pursuant  to
Section 8.1(c) or PNFP shall terminate this Agreement pursuant to Section 8.1(e)
or (f),  (B) at any  time  after  the date of this  Agreement  and  before  such
termination  there shall have been a Public  Proposal  with respect to CAVB that
has not  been  withdrawn  prior  to such  termination,  and  (C)  following  the
occurrence of such Public Proposal,  CAVB shall have intentionally breached (and
not  cured  after  notice  thereof)  any  of  its  representations,  warranties,
covenants or  agreements  set forth in this  Agreement,  which breach shall have
materially  contributed  to the failure of the Effective  Time to occur prior to
the  termination  of this  Agreement,  then  CAVB  shall  pay  one-third  of the
Termination  Fee on the  business day  following  such  termination;  and (D) if
within  twelve (12) months of the date of such  termination  of this  Agreement,
CAVB or any of its Subsidiaries  executes any definitive  agreement with respect
to,  or  consummates,  any  Acquisition  Transaction,  then  CAVB  shall pay the
remaining  two-thirds of the  Termination Fee upon the date of such execution or
consummation.

     (b) If either  party  fails to pay all amounts due to the other party under
Sections 8.2 or 8.3 on the dates  specified,  then the nonpaying party shall pay
all costs and expenses (including legal fees and expenses) incurred by the other
party in connection  with any action or proceeding  (including the filing of any
lawsuit) taken by it to collect such unpaid  amounts,  together with interest on
such  unpaid  amounts at the prime  lending  rate  prevailing  at such time,  as
published in the Wall Street  Journal,  from the date such amounts were required
to be paid until the date actually received by the other party.

     (c) The parties  acknowledge  that the agreements  contained in Section 8.2
and 8.3 are an integral part of the transactions  contemplated by this Agreement
and constitute  liquidated  damages and not a penalty,  and that,  without these
agreements, the parties would not have entered into this Agreement.

     (d) For  purposes of this  Agreement,  the term  "Acquisition  Transaction"
shall mean (i) the direct or indirect acquisition, purchase or assumption of all
or a substantial portion of the assets or deposits of CAVB, (ii) the acquisition
by any person of direct or indirect  beneficial  ownership  (including by way of
merger,  consolidation,  share  exchange  or  otherwise)  of 20% or  more of the
outstanding  shares of voting stock of CAVB,  or (iii) a merger,  consolidation,
business  combination,  liquidation,  dissolution  or similar  transaction of or
involving CAVB, other than a merger, business combination or similar transaction
pursuant to which persons who are shareholders of CAVB immediately prior to such
transaction  own 60% or more of the  voting  stock of the  surviving  entity (or
parent thereof)  immediately  after  consummation of such  transaction and, as a
result of such  transaction,  no person or group  (within the meaning of Section
13(d)(3)  of the  Exchange  Act)  holds 20% or more of the  voting  stock of the
surviving entity (or parent thereof) immediately following  consummation of such
transaction.

                                       46



     8.4  Amendment.  Subject to  compliance  with  applicable  law and  Section
1.1(b),  this Agreement may be amended by the parties hereto, by action taken or
authorized by their respective Boards of Directors,  at any time before or after
approval  of  the  matters  presented  in  connection  with  the  Merger  by the
shareholders of CAVB and PNFP; provided, however, that after any approval of the
transactions  contemplated  by this Agreement by the respective  shareholders of
CAVB or PNFP, there may not be, without further  approval of such  shareholders,
any  amendment  of this  Agreement  that  changes  the amount or the form of the
consideration  to be delivered  hereunder  to the holders of CAVB Common  Stock,
other than as contemplated by this Agreement.  This Agreement may not be amended
except by an  instrument  in  writing  signed  on behalf of each of the  parties
hereto.

     8.5 Extension; Waiver. At any time prior to the Effective Time, the parties
hereto,  by action taken or authorized by their  respective  Board of Directors,
may, to the extent legally  allowed,  (a) extend the time for the performance of
any of the obligations or other acts of the other parties hereto,  (b) waive any
inaccuracies in the  representations  and warranties  contained herein or in any
document  delivered  pursuant  hereto and (c) waive  compliance  with any of the
agreements or conditions  contained herein;  provided,  however,  that after any
approval of the  transactions  contemplated  by this Agreement by the respective
shareholders of CAVB or PNFP, there may not be, without further approval of such
shareholders,  any extension or waiver of this Agreement or any portion  thereof
which  reduces  the  amount  or  changes  the  form of the  consideration  to be
delivered  to the  holders  of  CAVB  Common  Stock  hereunder,  other  than  as
contemplated by this  Agreement.  Any agreement on the part of a party hereto to
any such  extension  or  waiver  shall be valid  only if set  forth in a written
instrument  signed on  behalf of such  party,  but such  extension  or waiver or
failure to insist on strict compliance with an obligation,  covenant,  agreement
or condition  shall not operate as a waiver of, or estoppel with respect to, any
subsequent or other failure.

                                  ARTICLE IX.
                               GENERAL PROVISIONS

representations or warranties  contained in Article III, in the case of PNFP, or
Article IV, in the case of CAVB, has had or would be reasonably likely to have a

the SEC in connection with the Merger, shall be borne equally by CAVB and PNFP.
