                             PIEDMONT BANCORP, INC.

<PAGE>
                  THIS AGREEMENT AND PLAN OF  REORGANIZATION  (the  "Agreement")
dated as of this 27th day of  December,  1999,  by and among  NATIONAL  COMMERCE
BANCORPORATION  ("NCBC"), a Tennessee  corporation which is registered as a bank
holding  company under the Bank Holding  Company Act of 1956 and whose principal
offices  are located at One  Commerce  Square,  Memphis,  Tennessee  38150,  and
PIEDMONT BANCORP, INC. ("PBI"), a North Carolina corporation which is registered
as a bank  holding  company and whose  principal  offices are located at 260 So.
Churton  Street,  Hillsborough,  North  Carolina.  NCBC  and PBI  are  sometimes
hereinafter called the "Parties."

                  Certain other  capitalized terms used in this Agreement and in
the related plan of Merger are defined below in Section 10.1.

                  A. PBI is the  beneficial  owner  and  holder of record of one
hundred percent (100%) of the issued and outstanding  shares of capital stock of
Hillsborough Savings Bank, Inc., SSB (the "Savings Bank Subsidiary").

                  B. The Board of Directors of PBI deems it desirable and in the
best interests of PBI, the Savings Bank  Subsidiary and the  shareholders of PBI
that PBI be merged  with and into NCBC,  which  would  survive the merger as the
Surviving  Corporation,  as  defined  herein  (the  "Merger"),  on the terms and
subject to the conditions set forth in this Agreement and in the manner provided
in the Plan of Merger annexed hereto as Exhibit 1 (the "Plan of Merger") and has
directed  that  this  Agreement  and the  Plan of  Merger  be  submitted  to the
shareholders of PBI with the recommendation that they be approved by them.

                  C. The Board of Directors  of NCBC deems it  desirable  and in
the best interests of NCBC and the  shareholders of NCBC that PBI be merged with
and into NCBC on the  terms  and  subject  to the  conditions  set forth in this
Agreement and in the manner provided in the Plan of Merger.

                  D.  The  Parties   intend   that  the  Merger   qualify  as  a
reorganization  pursuant to Section 368 of the Internal Revenue Code of 1986, as
amended  (the  "Code")  and  be  accounted  for  as a  pooling-of-interests  for
financial accounting purposes.

                  E. The  respective  Boards of  Directors  of NCBC and PBI have
each adopted  resolutions setting forth and adopting this Agreement and the Plan
of Merger,  and have directed that this Agreement and the annexed Plan of Merger
and all  resolutions  adopted  by  said  Boards  of  Directors  related  to this
Agreement,  be submitted with  appropriate  applications  to, and filed with all
applicable  Regulatory  Authority  as may be  necessary  in order to obtain  all
Consents  required  to  consummate  the  proposed  Merger  and the  transactions
contemplated in this Agreement in accordance  with this  Agreement,  the Plan of
Merger and applicable law.

                  F. The  respective  boards of  Directors  of NCBC and PBI have
agreed to cause NCBC and PBI to enter into the stock  option  agreement  annexed
hereto as Exhibit 2 (the "Stock Option  Agreement")  contemporaneously  with the
signing of this Agreement.

                  NOW, THEREFORE, in consideration of the foregoing premises and
the  mutual  representations,   warranties,   covenants  and  agreements  herein
contained  and for  other  good and  valuable  consideration,  the  receipt  and
sufficiency of which are hereby acknowledged, the Parties agree as follows:

Merger to NCBC,  PBI to any PBI Record  Holder or (iii)  adversely  impacts  the

                                    ARTICLE 2
             MANNER OF CONVERTING SHARES AND OPTIONS; EXCHANGE RATIO

                  2.1 Conversion;  Cancellation and Exchange of Shares; Exchange
Ratio.  At the Effective Time, by virtue of the Merger and without any action on
the part of NCBC, PBI, or the  shareholders of any of the foregoing,  the shares
of the constituent corporations shall be converted as follows:

                  (a) NCBC  Capital  Stock.  Each share of NCBC  Capital  Stock,
including  any  attached  rights to  purchase  NCBC  capital  stock,  issued and
outstanding  immediately  prior to the  Effective  Time shall remain  issued and
outstanding from and after the Effective Time.

                  (b) PBI Common  Stock.  Each share of PBI Common  Stock issued
and  outstanding  at the  Effective  Time shall cease to represent  any interest
(equity,  shareholder or otherwise) in PBI and shall  automatically be converted
exclusively  into,  and  constitute  only the right of each PBI Record Holder to
receive  in  exchange  for  such  Holder's   shares  of  PBI  Common  Stock  the
consideration  to which the PBI Record  Holder is  entitled  as provided in this
Section 2.1(b):

                  (i) The Exchange Ratio Calculation. Subject to any adjustments
which may be required by an event described in Subsection  2.1(b)(iii) below, at
and as of the Effective Time:


                         (A) Each share of the PBI Common Stock  outstanding  at
                  and as of the Effective Time shall be converted into the right
                  to receive  that number of shares of NCBC  Common  Stock equal
                  to:

                            (I) The quotient of the Net Purchase  Price (defined
                      below)  divided  by the NCBC  "Market  Price Per Share" as
                      defined hereinbelow,

                                   divided by

                            (II) The sum of the  number of shares of PBI  Common
                      Stock  outstanding at and as of the Effective Time and the
                      number of shares of PBI Common Stock issuable  pursuant to
                      options to  purchase  PBI Common  Stock to the extent that
                      such options are  outstanding  at and as of the  Effective
                      Time.

                  Notwithstanding the provisions of subsection (A) above, if the
Market Price Per Share shall be less than $20.70,  then each share of PBI Common
Stock  outstanding  at and as of the Effective  Time shall be converted into the
right to receive .60499 shares of NCBC Common Stock, and if the Market Price Per
Share shall exceed  $25.30,  then each share of PBI Common Stock  outstanding at
and as of the Effective Time shall be converted into the right to receive .49499
shares of NCBC Common Stock.

                         (B) "Net Purchase Price" shall be $34,500,000.


                            No share of PBI Common  Stock  shall be deemed to be
                      outstanding  or have any rights other than those set forth
                      in this  Section  2.1(b)  after  the  Effective  Time.  No
                      fractional  shares of NCBC Common Stock shall be issued in
<PAGE>
                      the Merger and, if after  aggregating all of the whole and
                      fractional  shares  of NCBC  Common  Stock  to which a PBI
                      Record  Holder shall be entitled  based upon this Exchange
                      Ratio  Calculation,  there should be a fractional share of
                      NCBC Common Stock  remaining,  such fractional share shall
                      be settled by a cash payment therefor  pursuant to Article
                      3 of this Agreement,  which cash settlement shall be based
                      upon the Market Price Per Share (as defined  below) of one
                      (1) full share of NCBC Common Stock.

                  (ii) Definition of "Market Price Per Share". The "Market Price
Per Share"  shall be the average of the  closing  price per share of NCBC Common
Stock on the Nasdaq (as  reported  by The Wall  Street  Journal) on the five (5)
trading day period ending two (2) trading days prior to the  Effective  Time, or
such earlier date as may be required by the Securities and Exchange Commission.

                  (iii) Effect of Stock  Splits,  Reverse  Stock  Splits,  Stock
Dividends and Similar Changes in the Capital of PBI. Should PBI effect any stock
splits,  reverse  stock  splits,  stock  dividends  or  similar  changes  in its
respective capital accounts subsequent to the

date of this Agreement but prior to the Effective  Time, the Exchange Ratio may,
in NCBC's sole discretion if such change in the capital  accounts  constitutes a
breach of any of PBI's representations,  warranties or covenants, be adjusted in
such a manner as the Board of  Directors  of NCBC shall deem in good faith to be
fair and reasonable in order to give effect to such changes. Notwithstanding the
foregoing,  nothing in this subparagraph (iii) shall be deemed to be a waiver of
the  inaccuracy of any  representation  or warranty or breach of any covenant by
PBI set forth herein.

                  (c)  Shares  Held by PBI or NCBC.  Each of the  shares  of PBI
Common Stock held by any PBI Company or by any NCBC Company,  in each case other
than in a  fiduciary  capacity  or as a result of debts  previously  contracted,
shall be cancelled and retired at the Effective Time and no Consideration  shall
be issued in exchange therefor.

                  2.2 Conversion of Stock Options.

                  (a) At the  Effective  Time,  all rights  with  respect to PBI
Common Stock pursuant to stock options ("PBI Options")  granted by PBI under the
PBI Option Plans,  which are outstanding at the Effective  Time,  whether or not
exercisable,  shall be  converted  into and become  rights with  respect to NCBC
Common  Stock,  and NCBC shall assume each PBI Option,  in  accordance  with the
terms  of the PBI  Option  Plan  and  stock  option  agreement  by  which  it is
evidenced.  From and after the Effective  Time,  (i) each PBI Option  assumed by
NCBC may be exercised solely for shares of NCBC Common Stock, (ii) the number of
shares of NCBC  Common  Stock  subject to such PBI Option  shall be equal to the
number of shares of PBI Common  Stock  subject  to such PBI  Option  immediately
prior to the Effective Time multiplied by the Exchange Ratio,  and (iii) the per
share  exercise  price under each such PBI Option  shall be adjusted by dividing
the per share  exercise  price under each such PBI Option by the Exchange  Ratio
and rounding down to the nearest cent. PBI agrees to take all necessary steps to
effectuate  the foregoing  provisions of this Section 2.2.  Notwithstanding  the
foregoing,  each stock option which is an "incentive stock option" under the PBI
Option Plan shall be adjusted as required by Section 424 of the Internal Revenue
Code of 1986, as amended (the "Code") and the regulations promulgated thereunder
so as to continue as an incentive stock option under Section 424 of the Code and
so as not to  constitute  a  modification,  extension  or  renewal of the option
within the meaning of Section 424(h) of the Code.
<PAGE>
                  2.3 Restricted Stock. At the Effective Time, each share of PBI
Common Stock held by the trustees under the Hillsborough Savings Bank, Inc., SSB
Management  Recognition Plan (the "MRP"),  including  unvested shares subject to
Awards as defined in the MRP heretofore  granted to participants  under the MRP,
shall be converted  into and exchanged for NCBC Common Stock and cash in lieu of
fractional  shares  pursuant to the  provisions  of Section 3.1 below,  and such
shares and cash  shall  thereafter  be held to be  delivered  to the  respective
participants  pursuant to the MRP. At the Effective Time, the MRP and each stock
grant  agreement  pursuant to which Awards were granted  shall remain in effect,
except that from and after the Effective  Time the MRP and each such stock grant
agreement  shall be amended as  necessary  to  provide  that:  (i) NCBC shall be
substituted for the Savings Bank Subsidiary; (ii) the NCBC Board of Directors or
its Compensation Committee shall be substituted for the Committee of the Savings
Bank Subsidiary  Board of Directors with respect to  administration  of the MRP;
(iii)  unvested  shares of NCBC Common Stock and cash  determined  in accordance
with the  provisions  of Section 3.1 below  shall be  substituted  for  unvested
shares of PBI Common  Stock;  (iv) no shares or other  assets in addition to the
shares of PBI Common Stock currently awarded under the MRP shall be purchased by
or for the MRP; and (v) shares,  cash or other interests in the MRP forfeited by
participants shall be retained by the Trustees and shall be available for making
additional Awards under the MRP.

                  2.4  ESOP.  The  parties  acknowledge  that  the  Hillsborough
Savings Bank,  Inc.  Employee Stock Ownership Plan will not be continued by NCBC
and that, as a result, in accordance with the terms of such Plan, such Plan will
terminate as a result of the Merger.

                  2.5  Anti-Dilution  Provisions.  In the event NCBC changes the
number  of shares of NCBC  Common  Stock  issued  and  outstanding  prior to the
Effective Time as a result of a stock split, stock dividend, or recapitalization
with respect to such stock and the record date  therefor (in the case of a stock
dividend) or the effective date thereof (in the case of a stock split or similar
recapitalization  for which a record date is not established)  shall be prior to
the Effective Time, the Exchange Ratio shall be proportionately adjusted.

                                    ARTICLE 3
                               EXCHANGE OF SHARES

                  3.1 Exchange  Procedures.  Promptly after the Effective  Time,
NCBC and PBI shall cause the  Exchange  Agent to mail to the PBI Record  Holders
appropriate  transmittal  materials  (which shall specify that delivery shall be
effected,   and  risk  of  loss  and  title  to  the  certificates   theretofore
representing shares of PBI Common Stock shall pass, only upon proper delivery of
such  certificates  to the Exchange  Agent).  The Exchange  Agent may  establish
reasonable  and customary  rules and  procedures in connection  with its duties.
After the Effective Time, each PBI Record Holder of PBI Common Stock (other than
shares to be cancelled  pursuant to Section 2.1(c) of this Agreement) issued and
outstanding   at  the  Effective  Time  shall   surrender  the   certificate  or
certificates  representing  such shares to the Exchange Agent and shall promptly
upon surrender thereof receive in exchange  therefor the Consideration  provided
in Section 2.1(b) of this Agreement,  together with all undelivered dividends or
distributions in respect of such shares (without  interest  thereon) pursuant to
Section 3.2 of this Agreement.  To the extent required by Section 2.1(b) of this
Agreement,  each PBI Record  Holder also shall  receive,  upon  surrender of the
certificate or certificates  representing  his or her shares of PBI Common Stock
<PAGE>
outstanding  immediately  prior  to the  Effective  Time,  cash  in  lieu of any
fractional  share of NCBC  Common  Stock to which such  holder may be  otherwise
entitled  (without  interest).  NCBC  shall  not be  obligated  to  deliver  the
Consideration  to which any PBI  Record  Holder is  entitled  as a result of the
Merger until such PBI Record  Holder  surrenders  such holder's  certificate  or
certificates  representing  the  shares  of PBI  Common  Stock for  exchange  as
provided in this Section  3.1. The  certificate  or  certificates  of PBI Common
Stock so surrendered shall be duly endorsed as the Exchange Agent may reasonably
require. Any other provision of this Agreement notwithstanding, neither NCBC nor
the Exchange  Agent shall be liable to a PBI Record  Holder for any amounts paid
or  properly  delivered  in good  faith to a  public  official  pursuant  to any
applicable   abandoned   property  Law.   Adoption  of  this  Agreement  by  the
shareholders  of PBI shall  constitute  ratification  of the  appointment of the
Exchange Agent.

                  3.2  Rights of Former  PBI Record  Holders.  At the  Effective
Time,  the stock  transfer  books of PBI shall be  closed as to  holders  of PBI
Common  Stock  outstanding  immediately  prior  to the  Effective  Time,  and no
transfer of PBI Common Stock by any PBI Record  Holder shall  thereafter be made
or recognized.  Until surrendered for exchange in accordance with the provisions
of Section 3.1 of this  Agreement,  each  certificate  theretofore  representing
shares of PBI Common  Stock  (other  than  shares to be  cancelled  pursuant  to
Section  2.1(c) of this  Agreement)  shall  from and after  the  Effective  Time
represent for all purposes only the right to receive the Consideration  provided
in  Section  2.1(b)  of  this  Agreement,  subject,  however,  to the  Surviving
Corporation's  obligation to pay any  dividends or make any other  distributions
with a record date prior to the Effective  Time which have been declared or made
by PBI in respect  of such  shares of PBI Common  Stock in  accordance  with the
terms of this Agreement and which remain unpaid at the Effective Time.  Whenever
a dividend or other  distribution  is declared by NCBC on the NCBC Common Stock,
the record date for which is at or after the  Effective  Time,  the  declaration
shall  include  dividends  or other  distributions  on all shares of NCBC Common
Stock issuable  pursuant to this Agreement,  but beginning sixty (60) days after
the Effective Time no dividend or other  distribution  payable to the holders of
record of NCBC Common  Stock as of any time  subsequent  to the  Effective  Time
shall  be  delivered  to a PBI  Record  Holder  until  such  PBI  Record  Holder
surrenders his or her  certificate or  certificates  evidencing PBI Common Stock
for  exchange  as  provided  in Section  3.1 of this  Agreement.  However,  upon
surrender  of such PBI Common  Stock  certificate,  both the NCBC  Common  Stock
certificate and any undelivered  dividends and cash payments  payable  hereunder
(without  interest)  shall be  delivered  and paid with  respect  to each  share
represented by such certificate.

                  3.3 Lost Certificates. Any PBI Record Holder whose certificate
representing  shares of PBI  Common  Stock has been lost,  destroyed,  stolen or
otherwise is missing shall be entitled to receive a certificate representing the
shares of NCBC Common Stock and cash in lieu of fractional shares to which he or
she  is  entitled  in  accordance  with  and  upon  compliance  with  conditions
reasonably  imposed by the Exchange  Agent  (including,  without  limitation,  a
requirement that the shareholder  provide a lost  instruments  indemnity bond in
form, substance and amount reasonably satisfactory to the Exchange Agent).

                      REPRESENTATIONS AND WARRANTIES OF PBI

                  Except as disclosed in the PBI Disclosure  Letter,  PBI hereby
represents and warrants to NCBC as follows:

                  4.1  Organization,  Standing and Power.  PBI is a  corporation
duly  organized,  validly  existing,  and in good standing under the laws of the
State of North  Carolina and has the  corporate  power and authority to carry on
its business in all material  respects as now  conducted  and to own,  lease and
operate its Assets.  PBI is duly qualified or licensed to transact business as a
foreign  corporation  in good  standing  in the states of the United  States and
foreign  jurisdictions  where the  character of its Assets or the conduct of its
business  requires  it  to  be  so  qualified  or  licensed,   except  for  such
jurisdictions  in which  the  failure  to be so  qualified  or  licensed  is not
reasonably likely to have,  individually or in the aggregate, a Material Adverse
Effect on PBI.

                  4.2 Authority; No Breach of Agreement.

                  (a) PBI has the  corporate  power and  authority  necessary to
execute,   deliver  and,  upon  obtaining  all  necessary   approvals  from  its
stockholders and appropriate Regulatory Authorities,  to perform its obligations
under  this  Agreement  and  effect  the Plan of Merger  and to  consummate  the
transactions  contemplated  hereby and  thereby.  The  execution,  delivery  and
performance of this Agreement and the Plan of Merger,  as  appropriate,  and the
consummation of the transactions contemplated herein and therein,  including the
Merger,  have been duly and validly authorized by all necessary corporate action
in respect thereof on the part of PBI, subject to the approval of this Agreement
and the Plan of Merger  by the  requisite  vote of  holders  of the  outstanding
shares of PBI Common  Stock,  which is the only  shareholder  vote  required for
approval of this Agreement and the Plan of Merger and consummation of the Merger
by PBI.  Subject to the receipt of such  requisite  shareholder  approval,  this
Agreement  represents a legal, valid and binding obligation of PBI,  enforceable
against  PBI in  accordance  with  its  terms  (except  in  all  cases  as  such
enforceability   may  be   limited   by   applicable   bankruptcy,   insolvency,
reorganization,   receivership,  conservatorship,  moratorium  or  similar  laws
affecting the  enforcement  of creditors'  rights  generally and except that the
availability  of the  equitable  remedy of specific  performance  or  injunctive
relief and other  equitable  remedies is subject to the  discretion of the court
before which any proceeding may be brought).

                  (b) Neither the  execution  and delivery of this  Agreement or
the Plan of Merger,  as appropriate,  by PBI, nor the consummation by PBI of the
transactions  contemplated hereby or thereby,  nor compliance by PBI with any of
the provisions hereof or thereof will (i) conflict with or result in a breach of
any provision of PBI's Articles of  Incorporation  or Bylaws,  or (ii) except as
disclosed in Section 4.2(b) of the PBI Disclosure  Letter,  constitute or result
in a Default  under,  or require any Consent (other than  shareholder  approval)
pursuant to, or result in the creation of any Lien on any material  Asset of any
PBI Company  under,  any Contract or Permit of any PBI Company  except as is not
reasonably likely to have,  individually or in the aggregate, a Material Adverse
Effect on PBI, or (iii) subject to receipt of the requisite Consents referred to
in Section 7.3 of this Agreement, violate any Law or Order applicable to any PBI
Company  or any of its  assets  except  as is not  reasonably  likely  to  have,
individually or in the aggregate, a Material Adverse Effect on PBI.
<PAGE>
                  (c) Other than in connection or compliance with the provisions
of the  Securities  Laws,  applicable  state  corporate  Laws,  the rules of the
American  Stock  Exchange  and other  than  Consents  required  from  Regulatory
Authorities,  and other than  notices to or filings  with the  Internal  Revenue
Service or the Pension  Benefit  Guaranty  Corporation  with  respect to any PBI
Employee  Plans or under  the HSR Act,  and  other  than  Consents,  filings  or
notifications which, if not obtained or made, are not reasonably likely to have,
individually  or in the aggregate,  a Material  Adverse Effect on PBI, no notice
to,  filing with,  or Consent of, any public body or authority is necessary  for
the consummation by PBI of the Merger and the other transactions contemplated in
this Agreement and the Plan of Merger.

                  (d) No PBI  Company is a party to, or subject to, or bound by,
any agreement or judgment,  order, letter of understanding,  writ,  prohibition,
injunction  or  decree  of any  court or other  governmental  body of  competent
jurisdiction,  or any law which would prevent the execution and delivery of this
Agreement and the Plan of Merger by PBI, or the consummation of the transactions
contemplated hereby and thereby,  and no action or proceeding is pending against
any PBI  Company  in which the  validity  of this  Agreement,  the  transactions
contemplated hereby or any action which has been taken by any of such Parties in
connection herewith or in connection with the transaction contemplated hereby is
at issue.

                  4.3 Capital Stock.

                  (a) The authorized capital stock of PBI consists of 20,000,000
shares of PBI Common Stock, no par value per share,  of which  2,502,700  shares
are issued and outstanding as of the date of this Agreement and 5,000,000 shares
of PBI  preferred  stock,  no par  value,  of which no  shares  are  issued  and
outstanding as of the date of this Agreement.  All of the issued and outstanding
shares of capital stock of PBI are duly and validly issued and  outstanding  and
are fully  paid and  nonassessable.  None of the  outstanding  shares of capital
stock of PBI have  been  issued in  violation  of any  preemptive  rights of the
current or past shareholders of PBI.

                  (b) Except as set forth in Section 4.3(a) of this Agreement or
pursuant to the PBI Option Plans,  there are no shares of capital stock or other
equity  securities of PBI outstanding and no outstanding  Rights relating to the
capital stock of PBI; provided, however, that 105,800 shares of PBI Common Stock
have been issued,  and are being held pursuant to restrictions set forth in, the
Hillsborough Savings Bank, Inc., SSB Management Recognition Plan.

                  4.4 PBI Subsidiaries.  PBI has disclosed in Section 4.4 of the
PBI Disclosure Letter all of the PBI  Subsidiaries(identifying  its jurisdiction
of incorporation,  each jurisdiction in which the character of its Assets or the
nature or conduct of its business requires it to be qualified and/or licensed to
transact  business except for such  jurisdictions  in which the failure to be so
qualified or licensed is not reasonably  likely to have,  individually or in the
aggregate,  a Material Adverse Effect on PBI, and the number of shares owned and
percentage ownership interest  represented by such share ownership).  PBI or one
of its wholly owned  Subsidiaries owns all of the issued and outstanding  shares
of capital stock (or other equity interests) of each PBI Subsidiary.  No capital
stock (or other equity interest) of any PBI Subsidiary is or may become required
to be issued  (other than to another PBI  Company) by reason of any Rights,  and
there are no Contracts by which any PBI Subsidiary is bound to issue (other than
to another PBI Company)  additional shares of its capital stock (or other equity
<PAGE>
interests)  or Rights or by which any PBI Company is or may be bound to transfer
any shares of the capital stock (or other equity interest) of any PBI Subsidiary
(other  than to another PBI  Company).  There are no  Contracts  relating to the
rights of any PBI  Company to vote or to  dispose  of any shares of the  capital
stock (or other equity  interests) of any PBI  Subsidiary.  All of the shares of
capital stock (or other equity  interests) of each PBI Subsidiary  held by a PBI
Company are fully paid and  nonassessable  under the  applicable  corporation or
similar Law of the  jurisdiction  in which such  Subsidiary is  incorporated  or
organized and are owned by the PBI Company free and clear of any Lien.  Each PBI
Subsidiary is either a bank or a corporation,  and each such  Subsidiary is duly
organized, validly existing, and (as to corporations) in good standing under the
laws of the  jurisdiction in which it is incorporated or organized,  and has the
corporate  power and authority  necessary  for it to own,  lease and operate its
Assets and to carry on its business in all material  respects as now  conducted.
Each PBI  Subsidiary  is duly  qualified  or licensed to transact  business as a
foreign  corporation  in good  standing  in the states of the United  States and
foreign jurisdictions where the character of its Assets or the nature or conduct
of its business  requires it to be so  qualified  or  licensed,  except for such
jurisdictions  in which  the  failure  to be so  qualified  or  licensed  is not
reasonably likely to have,  individually or in the aggregate, a Material Adverse
Effect on PBI.  The only PBI  Subsidiary  that is a  depository  institution  is
Savings Bank Subsidiary.  Savings Bank Subsidiary is an "insured institution" as
defined  in  the  Federal  Deposit  Insurance  Act  and  applicable  regulations
thereunder,  and the  Deposits in which are  insured by the Savings  Association
Insurance  Fund,  to the  extent  provided  by law.  The  minute  book and other
organizational  documents  and  Records for each PBI  Subsidiary  have been made
available  to NCBC for its review,  and are true and  complete  in all  material
respects as in effect as of the date of this Agreement and accurately reflect in
all material respects all amendments thereto and all proceedings of the Board of
Directors and shareholders thereof.

                  4.5  PBI  Financial  Statements.  PBI  has  delivered  or made
available to NCBC (or will deliver when available, with respect to periods ended
after the date of this Agreement but prior to the Effective Time) true,  correct
and complete copies of:

                  (a)  Annual  reports on Form 10-K,  including  any  amendments
thereto,  for the years ended June 30, 1997,  1998 and 1999,  and the  quarterly
report on Form 10-Q for the quarter ended  September 30, 1999, all as filed with
the SEC (the "PBI SEC Reports").  All financial  statements contained in the PBI
SEC Reports (the "PBI GAAP  Financial  Statements")  were prepared in accordance
with GAAP and fairly  present the financial  conditions,  results of operations,
changes  in  stockholders'  equity and cash flows of PBI as of the dates of such
financial  statements  and for the periods then ended  (subject,  in the case of
quarterly reports, to normal recurring year-end adjustments,  which were not and
were not expected to be material).

                  (b) All Call  Reports and Federal  Reserve  FRY-6  Reports and
FRY-9C  Reports,  including any  amendments  thereto,  filed with any Regulatory
Authorities  by PBI and any PBI  Subsidiary,  respectively,  for the years ended
December  31,  1996,   1997,  and  1998,  and  thereafter,   together  with  any
correspondence with any Regulatory  Authorities  concerning any of the aforesaid
financial  statements and Reports (the "PBI Regulatory  Financial  Statements").
Such PBI Regulatory Financial Statements (i) were (or will be) prepared from the
Records of PBI and/or each PBI  Subsidiary;  (ii) were (or will be)  prepared in
accordance with regulatory  accounting  principles  consistently  applied except
<PAGE>
where otherwise  noted;  (iii) present (or, when prepared,  will present) in all
material  respects PBI's and each PBI Subsidiary's  financial  condition and the
results of its operations, changes in stockholders' equity and cash flows at the
relevant dates thereof and for the periods covered thereby;  and (iv) contain or
reflect (or,  when  prepared,  will contain and  reflect)  all  adjustments  and
accruals  necessary for the accurate  presentation (in all material respects) of
PBI's and each PBI Subsidiary's financial condition and the results of PBI's and
each PBI Subsidiary's  operations and cash flows for the periods covered by such
financial  statements  (subject to any  exceptions as to  consistency  specified
therein or as may be indicated  in the notes  thereto or, in the case of interim
financial  statements,  to normal  recurring  year-end  adjustments that are not
material).

                  4.6 Absence of Undisclosed Liabilities. No PBI Company has any
Liabilities  that  are  reasonably  likely  to  have,  individually  or  in  the
aggregate,  a  Material  Adverse  Effect on PBI,  except  Liabilities  which are
accrued or reserved against in the PBI GAAP Financial Statements as of September
30, 1999, or reflected in the notes or schedules, if any, thereto, and delivered
with the PBI  Disclosure  Letter  prior to the date of this  Agreement  and (ii)
Liabilities  incurred in the ordinary  course of business  since  September  30,
1999. No PBI Company has incurred or paid any Liability  since the Balance Sheet
Date,  except for such  Liabilities  incurred or paid in the ordinary  course of
business  consistent  with past business  practice and which are not  reasonably
likely to have,  individually or in the aggregate,  a Material Adverse Effect on
PBI or in connection with the transactions contemplated by this Agreement.

                  4.7 Absence of Certain Changes or Events.  Except as described
in Section 4.7 of the PBI Disclosure Letter,  since the Balance Sheet Date there
has not been:

                      (a) Any material  transaction by any PBI Company which was
not undertaken in the ordinary course of business consistent with past practice.

                      (b) Any loss of a key employee or any damage,  destruction
or loss,  whether  or not  covered by  insurance,  which has had or which may be
reasonably expected to have a Material Adverse Effect on PBI.

                      (c) Any  acquisition  or disposition by any PBI Company of
any Asset having a fair market  value,  singularly  or in the aggregate for each
PBI Company,  in an amount  greater than Fifty  Thousand  Dollars  ($50,000.00),
except in the ordinary course of business consistent with past practice.

                      (d) Any  mortgage,  pledge or  subjection  to Lien, of any
kind  or  nature,  any of the  Assets  of any  PBI  Company,  except  to  secure
extensions  of credit in the ordinary  course of business  consistent  with past
practice.

                      (e) Any  amendment,  modification  or  termination  of any
Contract  relating  to any PBI  Company  or to which any PBI  Company is a party
which amendment, modification or termination would or may be reasonably expected
to have a Material Adverse Effect on PBI.

                      (f) Any  increase  in,  or  commitment  to  increase,  the
compensation payable or to become payable to any officer, director,  employee or
agent of any PBI Company, or any bonus payment or similar arrangement made to or
with any of such officers,  directors,  employees or agents,  other than routine
increases made in the ordinary course of business not
exceeding the greater of ten percent  (10%) per annum or Five  Thousand  Dollars
($5,000.00) for any of them individually.
<PAGE>
                      (g) Any incurring of,  assumption of, or taking of, by any
PBI Company, any Asset subject to any Liability, except for Liabilities incurred
or assumed or Assets taken  subsequent to the Balance Sheet Date in the ordinary
course of business consistent with past practice.

                      (h)  Except as are  applicable  to  state-chartered,  FDIC
insured savings banks and their Affiliates,  generally,  any material alteration
in the manner of keeping the books,  accounts or Records of any PBI Company,  or
in the accounting policies or practices therein reflected.

                      (i) Any  release  or  discharge  (or  partial  release  or
discharge) of any  obligation  or Liability of any Person  related to or arising
out of any loan  made by any PBI  Company,  except  in the  ordinary  course  of
business and in conformity  with past practice,  which,  individually  or in the
aggregate, would or may reasonably be expected to have a Material Adverse Effect
on PBI.

                  4.8 Tax Matters.

                  (a) All Tax  Returns  required  to be filed by or on behalf of
any of the PBI Companies have been timely filed or requests for extensions  have
been timely  filed,  granted and have not expired for periods ended on or before
June 30,  1999,  and will be filed,  or requests  for an  extension  of time for
filing will be filed,  on or before the date of the most recent  fiscal year end
immediately preceding the Effective Time, and all Tax Returns filed are complete
and accurate in all material respects. All Taxes shown on filed Tax Returns have
been paid. There is no audit, examination,  deficiency proceeding, or litigation
with  respect  to any  Taxes,  except  as  reflected  in the PBI GAAP  Financial
Statements or Section 4.8(a) of the PBI Disclosure  Letter.  All Taxes and other
Liabilities due with respect to completed and settled  examinations or concluded
Litigation have been paid.  There are no Liens with respect to Taxes upon any of
the Assets of the PBI Companies.

                  (b) None of the PBI  Companies  has  executed an  extension or
waiver of any statute of  limitations on the assessment or collection of any Tax
due (excluding such statutes that relate to years currently under examination by
the Internal Revenue Service or other  applicable  taxing  authorities)  that is
currently in effect.

                  (c) Adequate  provision for any Taxes due or to become due for
any of the PBI  Companies  for the period or periods  through and  including the
date of the  respective  PBI GAAP  Financial  Statements  has  been  made and is
reflected on such PBI GAAP Financial Statements.

                  (d) Reserved.

                  (e) Each of the PBI Companies is in compliance  with,  and its
Records contain  information  and documents  (including  properly  completed IRS
Forms W-9) necessary to comply with, all  applicable  information  reporting and
Tax withholding  requirements under federal,  state and local tax Laws, and such
records  identify with  specificity all accounts  subject to backup  withholding
under Section 3406 of the IRC, except for such instances of  non-compliance  and
such  omissions as are not  reasonably  likely to have,  individually  or in the
aggregate, a Material Adverse Effect on PBI.
<PAGE>
                  (f) There has not been an ownership  change, as defined in the
IRC Section  382(g),  of any of the PBI Companies that occurred  during or after
any Taxable Period in which the PBI Companies incurred a net operating loss that
carries over to any Taxable Period ending after June 30, 1999.

                  (g)  Except  as  set  forth  in  Section  4.8(g)  of  the  PBI
Disclosure Letter, none of the PBI Companies is a party to any tax allocation or
sharing  agreement  and  none of the  PBI  Companies  has  been a  member  of an
affiliated  group filing a consolidated  federal income tax return (other than a
group the common  parent of which was PBI) or has any Liability for taxes of any
Person (other than PBI and its Subsidiaries)  under Treasury  Regulation Section
1.1502-6  (or any  similar  provision  of  state,  local  or  foreign  Law) as a
transferee or successor or by contract or otherwise.

                  4.9  Allowance  for Possible  Loan Losses.  The  allowance for
possible loan or credit losses,  including any allowances or reserves for losses
on ORE and other collateral taken in satisfaction,  or partial satisfaction of a
debt previously  contracted (the "Allowance") shown on the consolidated  balance
sheets of PBI included in the most recent PBI  Regulatory  Financial  Statements
dated prior to the date of this  Agreement  was, and the Allowance  shown on the
consolidated  balance  sheets of PBI  included in the PBI  Regulatory  Financial
Statements as of dates  subsequent to the execution of this  Agreement and as of
the Closing Date will be, as of the dates thereof,  in the reasonable opinion of
management of PBI adequate (within the meaning of GAAP and applicable regulatory
requirements or guidelines) to provide for all known and reasonably  anticipated
losses  relating  to or  inherent  in the loan and lease  portfolios  (including
accrued  interest  receivables  and ORE reserves) of the PBI Companies and other
extensions of credit (including  letters of credit and commitments to make loans
or extend credit) by the PBI Companies as of the dates thereof, except where the
failure of such  Allowance  to be  adequate is not  reasonably  likely to have a
Material  Adverse  Effect on PBI.  Except as described in Section 4.9 of the PBI
Disclosure  Letter (by loan type,  loan number,  classification  and outstanding
balance),  no PBI Company has any Loan or other  extension  of credit  which has
been (or should have been in  management's  reasonable  opinion)  classified  as
"Other Assets  Especially  Mentioned,"  "Substandard,"  "Doubtful" or "Loss," or
similar  classifications,  that were not  classified in any PBI  Company's  most
recent  report of  examination.  Section 4.9 of the PBI  Disclosure  Letter also
lists all Loans or  extensions of credit which are included on any PBI Company's
"watch list." The net book value of any PBI Company's  assets  acquired  through
foreclosure in  satisfaction  of problem loans ("ORE") is carried on the balance
sheet of the PBI Financial  Statements at fair value at the time of  acquisition
less estimated  selling costs which  approximate the net realizable value of the
ORE in accordance with the American  Institute of Certified Public  Accountants'
Statement of Position 92-3.

                  4.10 Assets.  Except as  reflected  in the PBI GAAP  Financial
Statements or as set forth in Section 4.10 of the PBI Disclosure Letter, the PBI
Companies have good and marketable title, free and clear of all Liens, to all of
their  respective  Assets except to the extent that is not reasonably  likely to
have a  Material  Adverse  Effect  on  PBI.  All  tangible  Assets  used  in the
businesses of the PBI Companies are in good condition,  reasonable wear and tear
excepted,  and are usable in the  ordinary  course of business  consistent  with
PBI's past practices except to the extent that is not reasonably  likely to have
a  Material  Adverse  Effect on PBI.  All  Assets  which are  material  to PBI's
business on a consolidated  basis,  held under leases or subleases by any of the
PBI  Companies,  are held under  valid  Contracts  enforceable  in all  material
respects in accordance with their respective terms (except as enforceability may
be limited by applicable bankruptcy, insolvency, reorganization,  moratorium, or
<PAGE>
other laws affecting the enforcement of creditors'  rights  generally and except
that the  availability  of the  equitable  remedy  of  specific  performance  or
injunctive  relief and other equitable  remedies is subject to the discretion of
the court before which any proceedings  may be brought),  and each such Contract
is in full force and effect.  The PBI  Companies  currently  maintain  insurance
similar in amounts,  scope, and coverage that management believes to be adequate
in all material respects. None of the PBI Companies has received notice from any
insurance  carrier that (i) such  insurance  would be cancelled or that coverage
thereunder will be reduced or eliminated,  or (ii) premium costs with respect to
such policies of insurance will be substantially increased.  Except as set forth
in Section  4.10 of the PBI  Disclosure  Letter  there are  presently  no claims
pending  under any such  policies of insurance and no notices have been given by
any PBI Company under such policies.

                  4.11 Intellectual  Property.  All of the Intellectual Property
rights of the PBI Companies are in full force and effect and  constitute  legal,
valid and binding  obligations of the respective  parties  thereto except to the
extent that is not reasonably  likely to have a Material  Adverse Effect on PBI,
and there have not been, and there currently are not, any defaults thereunder by
any PBI  Company  except to the extent that is not  reasonably  likely to have a
Material  Adverse  Effect on PBI. A PBI Company owns or is the valid licensee of
all such  Intellectual  Property rights free and clear of all liens or claims of
infringement  except  to the  extent  that is not  reasonably  likely  to have a
Material  Adverse  Effect on PBI.  Except to the extent  that is not  reasonably
likely to have a Material  Adverse  Effect on PBI,  none of the PBI Companies or
their respective  predecessors,  has misused the Intellectual Property rights of
others  and none of the  Intellectual  Property  rights as used in the  business
conducted  by any such PBI Company  infringes  upon or  otherwise  violates  the
rights of any Person,  nor has any Person asserted a claim of such infringement.
Except as  disclosed in Section 4.11 of the PBI  Disclosure  Memorandum,  no PBI
Company is obligated to pay any royalties to any Person with respect to any such
Intellectual  Property.  Each PBI Company owns or has the valid right to use all
of the Intellectual Property rights material to PBI which it is presently using,
or in  connection  with  performance  of any material  Contract to which it is a
party.  No  officer,  director,  or  employee of any PBI Company is party to any
Contract  which  requires  such  officer,  director  or  employee  to assign any
interest in any  Intellectual  Property or keep  confidential any trade secrets,
proprietary data, customer information,  or other business information except as
disclosed  in Section  4.11 of the PBI  Disclosure  Letter,  which  restricts or
prohibits  such  officer,  director or  employee  from  engaging  in  activities
competitive with any person, including any PBI Company.

                  4.12  Environmental  Matters.  Except as set forth in  Section
4.12 of the PBI Disclosure Letter:


                  (a)  To  the   Knowledge  or  PBI,   each  PBI  Company,   its
Participation  Facilities,  and its Operating  Properties are, and have been, in
compliance  with all  Environmental  Laws,  except for violations  which are not
reasonably likely to have,  individually or in the aggregate, a Material Adverse
Effect on PBI.

                  (b) To the Knowledge of PBI, there is no litigation pending or
threatened before any court,  governmental agency or authority or other forum in
which  any PBI  Company  or any of its  Operating  Properties  or  Participation
Facilities  (or PBI in  respect  of such  Operating  Property  or  Participation
Facility) has been or, with respect to threatened litigation,  may be named as a
<PAGE>
defendant (i) for alleged noncompliance  (including by any predecessor) with any
environmental  law or (ii) relating to the release into the  environment  of any
Hazardous  Material,  whether or not occurring  at, on,  under,  adjacent to, or
affecting (or potentially  affecting) a site owned,  leased,  or operated by any
PBI Company or any of its  Operating  Properties  or  Participation  Facilities,
except for such litigation  pending or threatened that is not reasonably  likely
to have, individually or in the aggregate, a Material Adverse Effect on PBI.

                  (c) To the Knowledge of PBI,  during the period of (i) any PBI
Company's  ownership or operation of any of their respective current properties,
(ii) any PBI Company's  participation  in the  management  of any  Participation
Facility,  or (iii) any PBI  Company's  holding  of a  security  interest  in an
Operating  Property,  there have been no releases of Hazardous  Material in, on,
under,  adjacent to, or affecting (or potentially  affecting)  such  properties,
except  such  as are not  reasonably  likely  to  have,  individually  or in the
aggregate,  a Material  Adverse Effect on PBI. To the Knowledge of PBI, prior to
the  period of (i) any PBI  Company's  ownership  or  operation  of any of their
respective  current  properties,  (ii) any PBI  Company's  participation  in the
management of any Participation  Facility, or (iii) any PBI Company's holding of
a  security  interest  in an  Operating  Property,  there  were no  releases  of
Hazardous  Material in, on, under,  or affecting  such  property,  Participation
Facility or  Operating  Property,  except such as are not  reasonably  likely to
have, individually or in the aggregate, a Material Adverse Effect on PBI.

                  4.13  Compliance  with Laws. PBI is duly  registered as a bank
holding  company  under the BHC Act.  Each PBI Company has in effect all Permits
necessary  for it to own,  lease or operate its material  Assets and to carry on
its business as now conducted, except for those Permits the absence of which are
not reasonably  likely to have,  individually  or in the  aggregate,  a Material
Adverse  Effect on PBI,  and, to the  knowledge  of PBI,  there has  occurred no
Default  under any such  Permit  other than  Defaults  which are not  reasonably
likely to have,  individually or in the aggregate,  a Material Adverse Effect on
PBI. Except as set forth in Section 4.13 of the PBI Disclosure  Letter,  none of
the PBI Companies:

                  (a) Is, to the  knowledge  of PBI, in  violation  of any Laws,
Orders or  Permits  applicable  to its  business  or  employees  conducting  its
business,  except  for  violations  which  are not  reasonably  likely  to have,
individually or in the aggregate, a Material Adverse Effect on PBI; and

                  (b) Has received any  notification or  communication  from any
agency or department  of federal,  state or local  government or any  Regulatory
Authority  or the staff  thereof  (i)  asserting  that any PBI Company is not in
compliance with any of the Laws or Orders which such  governmental  authority or
Regulatory  Authority  enforces where such noncompliance is reasonably likely to
have,  individually or in the aggregate,  a Material Adverse Effect on PBI, (ii)
threatening to revoke any Permits the  revocation of which is reasonably  likely
to have,  individually or in the aggregate, a Material Adverse Effect on PBI, or
(iii)  requiring  any PBI Company to enter into or consent to the  issuance of a
cease  and  desist  order,  formal  agreement,   directive,   or  memorandum  of
understanding,  or to adopt any board resolution or similar  undertaking,  which
restricts  materially  the conduct of its business,  or in any manner relates to
its capital  adequacy,  its credit or reserve  policies,  its  management or the
payment of dividends.
<PAGE>
                  4.14 Labor  Relations.  No PBI  Company is the  subject of any
Litigation  asserting  that it or any other PBI Company has  committed an unfair
labor  practice  (within  the meaning of the  National  Labor  Relations  Act or
comparable  state  Law) or  seeking  to compel it or any  other PBI  Company  to
bargain with any labor organization as to wages or conditions of employment, nor
is there any strike or other labor dispute involving any PBI Company, pending or
threatened,  or to the Knowledge of PBI, is there any activity involving any PBI
Company's employees seeking to certify a collective  bargaining unit or engaging
in any other organization activity, in any case which might,  individually or in
the aggregate, have a Material Adverse Effect on PBI.

                  4.15 Employee Benefit Plans.

                  (a) PBI has disclosed in Section 4.15(a) of the PBI Disclosure
Letter,  and has  delivered or made  available to NCBC prior to the date of this
Agreement  copies in each case of,  all  pension,  retirement,  profit  sharing,
deferred compensation,  stock option,  employee stock ownership,  severance pay,
vacation,  bonus or other incentive plan, all other written  employee  programs,
arrangement or agreements,  all medical,  vision,  dental or other health plans,
all life insurance plans and all other employee  benefit plans or fringe benefit
plans,  including  "employee  benefit  plans" as that term is defined in Section
3(3) of ERISA,  currently adopted,  maintained by, sponsored in whole or in part
by, or  contributed  to by any PBI Company or ERISA  Affiliate  (defined  below)
thereof for the benefit of employees, retirees, dependents,  spouses, directors,
independent  contractors,  or other  beneficiaries  and under  which  employees,
retirees,  dependents,  spouses,  directors,  independent contractors,  or other
beneficiaries  are  eligible  to  participate  (collectively  the  "PBI  Benefit
Plans").  Any of the PBI Benefit  Plans which is an  "employee  pension  benefit
plan," as that term is defined in Section  3(2) of ERISA,  is referred to herein
as a "PBI ERISA  Plan."  Each PBI ERISA  Plan  which is also a "defined  benefit
plan" (as defined in IRC Section 414(j)) is referred to herein as a "PBI Pension
Plan." No PBI  Pension  Plan is or has been a  multi-employer  plan  within  the
meaning of Section 3(37) of ERISA.

                  (b)  Except  as set  forth  in  Section  4.15(b)  of  the  PBI
Disclosure  Letter,  all PBI Benefit Plans are in compliance with the applicable
terms of ERISA, the IRC and any other applicable laws the breach or violation of
which  are  reasonably  likely  to have,  individually  or in the  aggregate,  a
Material  Adverse  Effect on PBI.  Each PBI ERISA Plan which is  intended  to be
qualified under IRC Section 401(a) has received a favorable determination letter
from the Internal  Revenue  Service,  and PBI is not aware of any  circumstances
likely to result  in  revocation  of any such  favorable  determination  letter.
Except as set forth in Section  4.15(b)  of the PBI  Disclosure  Letter,  no PBI
Company has engaged in a transaction  with respect to any PBI Benefit Plan that,
assuming the taxable  period of such plan  expired as of the date hereof,  would
subject any PBI  Company to a tax imposed by either IRC Section  4975 or Section
502(i) of ERISA in amounts which are reasonably likely to have,  individually or
in the aggregate, a Material Adverse Effect on PBI.

                  (c)  Except  as  disclosed  in  Section  4.15(e)  of  the  PBI
Disclosure  Letter, no PBI Company has any liability for retiree health and life
benefits under any of the PBI Benefit Plans to former employees and there are no
restrictions  on the rights of such PBI Company to amend or  terminate  any such
retiree health or benefit plan without incurring  liability  thereunder which is
reasonably likely to have a Material Adverse Effect on PBI.
<PAGE>
                  (d)  Except  as  disclosed  in  Section  4.15(f)  of  the  PBI
Disclosure Letter,  neither the execution and delivery of this Agreement nor the
consummation  of the  transactions  contemplated  hereby  will (i) result in any
payment (including severance,  unemployment  compensation,  golden parachute, or
otherwise)  becoming due to any director or any employee of any PBI Company from
any PBI Company  under any PBI Benefit  Plan or  otherwise,  (ii)  increase  any
benefits  otherwise  payable  under any PBI Benefit Plan, or (iii) result in any
acceleration of the time of payment or vesting of any such benefit.

                  (e) The present  values of all accrued  deferred  compensation
entitlements   (including   entitlements   under  any  executive   compensation,
supplemental  retirement  or  employment  agreement)  of  employees  and  former
employees  of any PBI Company  and their  respective  beneficiaries,  other than
entitlements  accrued  pursuant  to  funded  retirement  plans  subject  to  the
provisions of IRC Section 412 or Section 302 of ERISA, have been fully reflected
on the PBI GAAP Financial Statements to the extent required by and in accordance
with GAAP.

                  4.16 Material  Contracts.  Except as disclosed in Section 4.16
of the  PBI  Disclosure  Letter,  none of the PBI  Companies,  nor any of  their
respective  assets,  businesses  or  operations,  is a party  to, or is bound or
affected  by,  or  receives  benefits  under  (i)  any  employment,   severance,
termination,  consulting or retirement contract providing for aggregate payments
to any  Person in any  calendar  year in excess of  $10,000  or total  aggregate
payments of $50,000 to all Persons receiving benefits (ii) any contract relating
to the borrowing of money by any PBI Company or the guarantee by any PBI Company
of any such obligation  (other than contracts  evidencing  deposit  liabilities,
purchases of federal funds, fully secured repurchase agreements and Federal Home
Loan Bank advances of depository institution  subsidiaries,  trade payables, and
contracts  relating to borrowings or guarantees  made in the ordinary  course of
business),  (iii) any contracts  which prohibit or restrict any PBI Company from
engaging in any business  activities in any geographic area, line of business or
otherwise in  competition  with any other person,  (iv) any  exchange-traded  or
over-the-counter  swap, forward,  future, option, cap, floor or collar financial
contract,  or any other interest rate or foreign  currency  protection  contract
(not disclosed in the PBI GAAP Financial  Statements delivered prior to the date
of this Agreement) which is a financial  derivative  contract (including various
combinations  thereof), and (v) any other material contract or amendment thereto
that would be required to be filed as an exhibit to a PBI SEC Report (whether or
not PBI is subject to the filing  requirements of the SEC) filed (or which would
have been filed if PBI were subject to the SEC  reporting  requirements)  by PBI
with the SEC prior to the date of this  Agreement  (together  with all contracts
referred  to  in  Sections  4.10  and  4.15(a)  of  this   Agreement  (the  "PBI
Contracts")).  With  respect  to each PBI  Contract:  (i) no PBI  Company  is in
Default  thereunder,  and (ii) no other  party to any such  contract  is, to the
Knowledge  of PBI,  in Default in any  respect or has  repudiated  or waived any
material  provision  thereunder,  other than Defaults  which are not  reasonably
likely to have,  individually or in the aggregate,  a Material Adverse Effect on
PBI.  Except as set forth in Section 4.16 of the PBI Disclosure  Letter,  all of
the indebtedness of any PBI Company for money borrowed is prepayable at any time
by such PBI Company without penalty or premium.
<PAGE>
                  4.17 Legal Proceedings. There is no Litigation pending, or, to
the Knowledge of PBI,  threatened against any PBI Company, or against any Asset,
interest,  or  right  of  any  of  them  that  is  reasonably  likely  to  have,
individually  or in the  aggregate,  a Material  Adverse  Effect on PBI, nor are
there any orders of any Regulatory Authorities,  other governmental authorities,
or arbitrators  outstanding against any PBI Company,  that are reasonably likely
to have,  individually  or in the aggregate,  a material  Adverse Effect on PBI.
Section  4.17 of the PBI  Disclosure  Letter  includes a report of all  material
litigation as of the date of this  Agreement to which any PBI Company is a party
and which names a PBI Company as a defendant or cross-defendant.

                  4.18  Reports.  Since  January 1, 1996,  each PBI  Company has
timely filed all reports and statements,  together with any amendments  required
to be made with respect thereto,  that it was required to file with (i) the SEC,
if applicable, including Forms 10-K, Forms 10-Q, Forms 8-K and proxy statements,
(ii) all other Regulatory Authorities, and (iii) any applicable state securities
or banking  authorities (except failures to file which are not reasonably likely
to have, individually or in the aggregate, a Material Adverse Effect on PBI). As
of their  respective  dates,  each of such reports and documents,  including the
financial statements,  exhibits, and schedules thereto, complied in all material
respects with all applicable  laws. As of its respective  date, each such report
and document did not, in all material respects,  contain any untrue statement of
a material fact or omit to state a material  fact required to be stated  therein
or necessary to make the statements made therein,  in light of the circumstances
under which they were made, not misleading.

                  4.19 Statements True and Correct.  No statement,  certificate,
instrument or other  writing  furnished or to be furnished by any PBI Company to
NCBC pursuant to this Agreement or any other document,  agreement, or instrument
referred to herein contains,  or will contain,  any untrue statement of material
fact or will omit to state a  material  fact  necessary  to make the  statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.  None  of the  information  supplied  or to be  supplied  by any PBI
Company or any Affiliate thereof for inclusion in the Registration  Statement to
be filed by NCBC  with the SEC will,  when the  Registration  Statement  becomes
effective,  be false or misleading with respect to any material fact, or omit to
state any material fact necessary to make the statements therein not misleading.
None of the  information  supplied  or to be  supplied by any PBI Company or any
Affiliate  thereof for  inclusion  in the Proxy  Statement to be mailed to PBI's
shareholders  in  connection  with  the  shareholders'  meeting,  and any  other
documents to be filed by a PBI Company or any Affiliate  thereof with the SEC or
any other Regulatory Authority in connection with the transactions  contemplated
thereby, will, at the respective time such documents are filed, and with respect
to the Proxy  Statement,  when first mailed to the  shareholders of PBI, contain
any untrue  statement  of  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,  or, in the case of the Proxy Statement or
any amendment  thereof or supplement  thereto,  at the time of the shareholders'
meeting,  contain any untrue  statement of material  fact,  or omit to state any
material  fact  necessary  to  make  the  statement  therein,  in  light  of the
circumstances under which they were made, not misleading. All documents that any
PBI  Company  or any  Affiliate  thereof  is  responsible  for  filing  with any
regulatory  authority in connection with the  transactions  contemplated  hereby
will  comply  as to  form  in all  material  respects  with  the  provisions  of
applicable Law.
<PAGE>
                  4.20 Accounting,  Tax and Regulatory Matters. To the Knowledge
of PBI,  no PBI  Company  or any  Affiliate  thereof  has taken any action or is
affected by any fact or  circumstance  that is reasonably  likely to (i) prevent
the transactions contemplated hereby, including the Merger, from qualifying as a
reorganization  within  the  meaning  of  Section  368(a)  of the  IRC,  or (ii)
materially  impede or delay  receipt of any Consents of  Regulatory  Authorities
referred to in Section 8.1(b) of this Agreement or result in the imposition of a
condition or  restriction  of the type  referred to in the last sentence of such
section.  PBI has made stock repurchases as described in Section 4.20 of the PBI
Disclosure  Letter,  which,  depending upon facts related to NCBC,  could affect
qualification of the transactions  contemplated hereby for  pooling-of-interests
accounting treatment.

                  4.21  State  Takeover  Laws.  Except  for  provisions  in  the
Articles of Incorporation of PBI and the Savings Bank Subsidiary, no PBI Company
has  taken  any  action  designed  or  intended  to  require  the   transactions
contemplated  by this  Agreement  and the  Plan of  Merger  to  comply  with any
applicable  "moratorium," "fair price," "business combination," "control share,"
or other anti-takeover laws (collectively "Takeover Laws"), including Articles 9
and 9A of the North Carolina Business Corporation Act.

                  4.22 Articles of  Incorporation  Provisions.  Each PBI Company
has taken all action so that the entering into of this Agreement and the Plan of
Merger  and  the   consummation  of  the  Merger  and  the  other   transactions
contemplated by this Agreement and the Plan of Merger do not and will not result
in the grant of any rights to any  Person  under the  Articles,  Bylaws or other
governing  instruments  of any PBI Company  (other than their  rights under this
Agreement  and the Plan of Merger and  voting,  dissenters'  appraisal  or other
similar  rights)  or  restrict  or  impair  the  ability  of  NCBC or any of its
Subsidiaries to vote, or otherwise to exercise the rights of a shareholder  with
respect  to,  shares  of any PBI  Company  that may be  directly  or  indirectly
acquired or controlled by it.

                  4.23 Charter Documents.  PBI has previously provided,  or made
available to, NCBC true and correct copies of the Articles of Incorporation  and
Bylaws of PBI and the Articles of Incorporation  and Bylaws of each PBI Company,
as amended to date, and each are in full force and effect.

                  4.24 Year 2000 Matters.  The computer software operated by PBI
which is material to the conduct of its  business is capable of  providing or is
being  adapted  to provide  uninterrupted  millennium  functionality  to record,
store,  process and present  calendar dates falling on or after January 1, 2000,
in  substantially  the same  manner  and with  the  same  functionality  as such
software records,  stores, processes and presents such calendar dates falling on
or before December 31, 1999,  except as would not have a Material Adverse Effect
on PBI.  PBI has not  received  and does not  expect  to  receive  a "Year  2000
Deficiency  Notification  Letter"  (as  such  term is  employed  in the  Federal
Reserve's  Supervision  and Regulation  Letter No. SR 98-3(SUP),  dated March 4,
1998).  PBI has disclosed or made available to NCBC a complete and accurate copy
of PBI's  plan for  addressing  the issues  set forth in the  statements  of the
Federal Financial Institutions  Examination Council, dated May 5, 1997, entitled
"Year 2000 Project  Management  Awareness," and December 1997,  entitled "Safety
and Soundness Guidelines Concerning the Year 2000 Business Risk," as such issues
affect  PBI.  The costs of the  adaptions  and  compliance  referred  to in this
Section 4.24 are not expected to have a Material Adverse Effect on PBI.

                                    ARTICLE 5
                     REPRESENTATIONS AND WARRANTIES OF NCBC

                  Except as disclosed in the NCBC Disclosure Letter, NCBC hereby
represents and warrants to PBI that:

                  5.1  Organization,  Standing and Power.  NCBC is a corporation
duly  organized,  validly  existing and in good  standing  under the laws of the
State of Tennessee,  and has the  corporate  power and authority to carry on its
business as now  conducted  and to own,  lease and operate its material  assets.
NCBC is duly qualified or licensed to transact business as a foreign corporation
in good  standing in the states of the United  States and foreign  jurisdictions
where the  character  of its assets or the  nature or  conduct  of its  business
requires it to be so  qualified or licensed,  except for such  jurisdictions  in
which the failure to be so  qualified  or licensed is not  reasonably  likely to
have, individually or in the aggregate, a Material Adverse Effect on NCBC.

                  5.2 Authority; No Breach by Agreement.

                  (a) NCBC has the corporate  power and  authority  necessary to
execute,  deliver  and  perform  its  obligations  under this  Agreement  and to
consummate the transactions  contemplated  hereby.  The execution,  delivery and
performance of this Agreement and the Plan of Merger and the consummation of the
transactions  contemplated  herein,  including  the  Merger,  have been duly and
validly  authorized by all necessary  corporate action in respect thereof on the
part of NCBC. This Agreement represents a legal, valid and binding obligation of
NCBC, enforceable against NCBC in accordance with its terms (except in all cases
as such  enforceability  may be limited by  applicable  bankruptcy,  insolvency,
reorganization,   moratorium  or  similar  laws  affecting  the  enforcement  of
creditors'  rights  generally and except that the  availability of the equitable
remedy of specific performance or injunctive relief is subject to the discretion
of the court before which any proceeding may be brought).

                  (b) Neither the  execution  and delivery of this  Agreement by
NCBC, nor the consummation by NCBC of the transactions  contemplated hereby, nor
compliance by NCBC with any of the  provisions  hereof will (i) conflict with or
result in a breach of any  provision of any NCBC  Company's  Charter (or similar
governing  instrument)  or  Bylaws,  or (ii)  constitute  or result in a Default
under, or require any Consent pursuant to, or result in the creation of any Lien
on any  assets  of any NCBC  Company  under any  Contract  or Permit of any NCBC
Company,  or (iii) subject to receipt of the requisite  approvals referred to in
Section  8.1(b) of this  Agreement,  violate any Law or Order  applicable to any
NCBC Company or any of their respective Material Assets.

                  (c) Other than in connection or compliance with the provisions
of the  Securities  Laws,  applicable  state  corporate law and the rules of the
NASDAQ, and other than Consents required from Regulatory Authorities,  and other
than  notices to or filings  with the  Internal  Revenue  Service or the Pension
Benefit  Guaranty  Corporation  with respect to any employee  benefit plans,  or
under the HSR Act, and other than Consents,  filings or notifications  which, if
not obtained or made, are not reasonably likely to have,  individually or in the
aggregate,  a Material  Adverse  Effect on NCBC,  no notice to,  filing with, or
Consent of, any public body or authority is necessary  for the  consummation  by
NCBC of the Merger and the other transactions contemplated in this Agreement and
the Plan of Merger.
<PAGE>
                  (d) No NCBC Company is a party to, or subject to, or bound by,
any agreement or judgment,  order, letter of understanding,  writ,  prohibition,
injunction  or  decree  of any  court or other  governmental  body of  competent
jurisdiction,  or any law which would prevent the execution and delivery of this
Agreement  and  the  Plan  of  Merger  by  NCBC,  or  the  consummation  of  the
transactions  contemplated  hereby and thereby,  and no action or  proceeding is
pending  against any NCBC Company in which the validity of this  Agreement,  the
transactions  contemplated  hereby or any action  which has been taken by any of
such  Parties in  connection  herewith  or in  connection  with the  transaction
contemplated hereby is at issue.

                  5.3 Capital Stock. The currently  authorized  capital stock of
NCBC  consists  of (i)  175,000,000  shares  of  NCBC  Common  Stock,  of  which
108,346,501  shares are issued and outstanding as of November 30, 1999, and (ii)
5,000,000  shares of NCBC  Preferred  Stock,  of which no shares  are issued and
outstanding. All of the issued and outstanding shares of NCBC Capital Stock are,
and all of the shares of NCBC Common  Stock to be issued in exchange  for shares
of PBI Common Stock upon  consummation of the Merger,  when issued in accordance
with the  terms  of this  Agreement,  will  be,  duly  and  validly  issued  and
outstanding  and  fully  paid  and  nonassessable  under  the  TBCA and the NCBC
Charter.  NCBC has reserved  for issuance a sufficient  number of shares of NCBC
Common  Stock  for the  purpose  of  issuing  shares  of NCBC  Common  Stock  in
accordance with the provisions of Section 2.1(b) and 2.2 of this Agreement.

                  5.4 SEC Filings; Financial Statements.

                  (a) NCBC has filed and made available to PBI all SEC documents
required to be filed by NCBC since  December 31, 1997 (the "NCBC SEC  Reports").
The NCBC SEC Reports (i) at the time filed,  complied in all  material  respects
with the applicable requirements of the Securities Laws and (ii) did not, at the
time they were filed (or, if amended or superseded by a filing prior to the date
of this Agreement, then on the date of such filing) contain any untrue statement
of a material  fact or omit to state a material  fact  required  to be stated in
such NCBC SEC Reports or necessary in order to make the  statements in such NCBC
SEC  Reports,  in light of the  circumstances  under  which they were made,  not
misleading. Except for NCBC Subsidiaries that are registered as brokers, dealers
or  investment  advisors,  no  NCBC  Subsidiary  is  required  to  file  any SEC
Documents.

                  (b) Each of the NCBC Financial Statements (including,  in each
case, any related notes)  contained in the NCBC SEC Reports,  including any NCBC
SEC Reports filed after the date of this  Agreement  until the  Effective  Time,
complied or will comply as to form in all material  respects with the applicable
published rules and regulations of the SEC with respect thereto,  was or will be
prepared in accordance  with GAAP applied on a consistent  basis  throughout the
periods  involved  (except as may be  indicated  in the notes to such  financial
statements or, in the case of unaudited interim statements, as permitted by Form
10-Q of the SEC), and fairly presented in all material respects the consolidated
financial  position of NCBC and its  Subsidiaries as at the respective dates and
the  consolidated  results  of its  operations  and cash  flows for the  periods
indicated,  except that the unaudited interim  statements were or are subject to
normal and recurring year-end  adjustments which were not or are not expected to
be material in amount or effect.

                  (c)  Nothing  has come to the  attention  of NCBC which  would
require a material  change to its most recently  filed SEC  Documents  since the
date of such filing.
<PAGE>
                  5.5 Absence of  Undisclosed  Liabilities.  No NCBC Company has
any  liabilities  that are  reasonably  likely to have,  individually  or in the
aggregate,  a Material  Adverse  Effect on NCBC,  except  liabilities  which are
accrued or reserved  against in the  consolidated  balance  sheets of NCBC as of
September 30, 1999, included in the NCBC Financial  Statements  reflected in the
notes  thereto.  No NCBC  Company has incurred or paid any  Liability  since the
Balance Sheet Date, except for such Liabilities incurred or paid in the ordinary
course of business  consistent  with past  business  practice  and which are not
reasonably likely to have,  individually or in the aggregate, a Material Adverse
Effect  on NCBC or in  connection  with the  transactions  contemplated  by this
Agreement.
                  5.6 Absence of Certain  Changes or Events.  Since December 31,
1998,  except as disclosed in the NCBC Financial  Statements  delivered prior to
the date of this  Agreement  or  contemplated  by  pending  federal  legislation
applicable to financial institutions  generally,  (i) there have been no events,
changes  or  occurrences  which  have  had,  or are  reasonably  likely to have,
individually  or in the aggregate,  a Material  Adverse Effect on NCBC, and (ii)
the NCBC  Companies  have not taken any  action,  or failed to take any  action,
prior to the date of this Agreement, which action or failure, if taken after the
date of this  Agreement,  would  represent  or  result in a  material  breach or
violation of any of the covenants  and  agreements of NCBC provided in Article 6
of this Agreement or would have a Material Adverse Effect on NCBC..

                  5.7 Compliance  with Laws.  NCBC is duly  registered as a bank
holding  company  under the BHC Act and as a savings  and loan  holding  company
under the HOLA. Each NCBC Company has in effect all Permits  necessary for it to
own,  lease or operate its  material  assets and to carry on its business as now
conducted,  and there has  occurred no default  under any such  permit.  No NCBC
Company:

                  (a) Is in violation of any Laws, Orders or Permits  applicable
to its business or employees conducting its business; and

                  (b) Has received any  notification or  communication  from any
agency or department  of federal,  state or local  government or any  Regulatory
Authority  or the staff  thereof (i)  asserting  that any NCBC Company is not in
compliance with any of the Laws or Orders which such  governmental  authority or
Regulatory Authority enforces,  (ii) threatening to revoke any Permits, or (iii)
requiring  any NCBC  Company to enter into or consent to the issuance of a cease
and desist  order,  formal  agreement,  directive,  commitment  or memorandum or
understanding,  or to adopt any board resolution or similar  undertaking,  which
restricts  materially  the conduct of its business,  or in any manner relates to
its capital  adequacy,  its credit or reserve policies,  its management,  or the
payment of dividends.

                  5.8 Legal  Proceedings.  There is no Litigation  instituted or
pending, or, to the Knowledge of NCBC,  threatened (or unasserted but considered
probable of  assertion  and which if asserted  would have at least a  reasonable
probability of an unfavorable  outcome) against any NCBC Company, or against any
Asset,  interest  or right of any of them,  that is  reasonably  likely to have,
individually  or in the  aggregate,  a Material  Adverse Effect on NCBC; nor are
there any orders of any regulatory authorities,  other governmental authorities,
or arbitrators against any NCBC Company.

                  5.9 Reports. Since January 1, 1996, NCBC has filed all reports
and  statements,  together with any amendments  required to be made with respect
thereto,  that it was  required  to file  with (i) the SEC,  including,  but not
limited to, Forms 10-K, Forms 10-Q, Forms 8-K and proxy  statements,  (ii) other
Regulatory  Authorities,  and (iii) any applicable  state  securities or banking
<PAGE>
authorities  (except, in the case of state securities  authorities,  failures to
file which are not reasonably likely to have,  individually or in the aggregate,
a Material Adverse Effect on NCBC). As of their respective  dates,  each of such
reports  and  documents,  including  the  financial  statements,   exhibits  and
schedules  thereto,  complied in all material respects with all applicable Laws.
As of its  respective  date,  each such  report  and  document  did not,  in all
material  respects,  contain any untrue  statement of a material fact or omit to
state a material  fact  required to be stated  therein or  necessary to make the
statements  made therein,  in light of the  circumstances  under which they were
made, not misleading.

                  5.10 Statements True and Correct.  No statement,  certificate,
instrument or other writing  furnished or to be furnished by any NCBC Company or
any Affiliate  thereof to PBI pursuant to this Agreement or any other  document,
agreement or instrument  referred to herein  contains or will contain any untrue
statement of material  fact or will omit to state a material  fact  necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.  None of the information supplied or to be supplied by any
NCBC  Company  or any  Affiliate  thereof  for  inclusion  in  the  Registration
Statement  to be  filed  by NCBC  with the  SEC,  will,  when  the  Registration
Statement becomes effective, be false or misleading with respect to any material
fact,  or omit to state  any  material  fact  necessary  to make the  statements
therein not misleading.  None of the  information  supplied or to be supplied by
any NCBC Company or any Affiliate  thereof for inclusion in the Proxy  Statement
to be mailed to PBI Shareholders in connection with the shareholders'  meetings,
and any other documents to be filed by any NCBC Company or any Affiliate thereof
with  the  SEC  or  any  other  Regulatory  Authority  in  connection  with  the
transactions  contemplated  hereby,  will, at the respective time such documents
are filed,  and with  respect to the Proxy  Statement,  when first mailed to the
shareholders  of PBI, be false or misleading  with respect to any 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,  or, in
the case of the Proxy Statement or any amendment thereof or supplement  thereto,
at the time of the  shareholders'  meeting,  contain  any  untrue  statement  of
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.  All documents that any NCBC Company or any Affiliate thereof is
responsible  for filing with any  Regulatory  Authority in  connection  with the
transactions contemplated hereby will comply as to form in all material respects
with the provisions of applicable law.

                  5.11 Accounting,  Tax and Regulatory  Matters. No NCBC Company
or any  Affiliate  thereof has taken any action or has any knowledge of any fact
or  circumstance  relating to NCBC that is reasonably  likely to (i) prevent the
transactions  contemplated  hereby,  including the Merger,  from  qualifying for
pooling-of-interests  accounting  treatment  or as a  reorganization  within the
meaning of IRC Section 368(a), or (ii) materially impede or delay receipt of any
Consents  of  Regulatory  Authorities  referred  to in  Section  8.1(b)  of this
Agreement or result in the  imposition of a condition or restriction of the type
referred to in the last sentence of such Section.

                  5.12 Tax Matters.

                  (a) All Tax  Returns  required  to be filed by or on behalf of
any of the NCBC Companies have been timely filed or requests for extensions have
been timely  filed,  granted and have not expired for periods ended on or before
December 31, 1998,  and on or before the date of the most recent fiscal year end
immediately preceding the Effective Time, and all Tax Returns filed are complete
and accurate in all material respects. All Taxes shown on filed Tax Returns have
<PAGE>
been paid. There is no audit, examination,  deficiency proceeding, or litigation
with respect to any Taxes, except as reflected in the NCBC Financial  Statements
or  Section  5.12(a)  of  the  NCBC  Disclosure  Letter.  All  Taxes  and  other
Liabilities due with respect to completed and settled  examinations or concluded
Litigation have been paid.  There are no Liens with respect to Taxes upon any of
the Assets of the NCBC Companies.

                  (b) None of the NCBC  Companies  has  executed an extension or
waiver of any statute of  limitations on the assessment or collection of any Tax
due (excluding such statutes that relate to years currently under examination by
the Internal Revenue Service or other  applicable  taxing  authorities)  that is
currently in effect.

                  (c) Adequate  provision for any Taxes due or to become due for
any of the NCBC  Companies  for the period or periods  through and including the
date of the respective NCBC Financial  Statements has been made and is reflected
on such NCBC Financial Statements.

                  (d) Reserved.

                  (e) Each of the NCBC Companies is in compliance  with, and its
Records contain  information  and documents  (including  properly  completed IRS
Forms W-9) necessary to comply with, all  applicable  information  reporting and
Tax withholding  requirements under federal,  state and local tax Laws, and such
records  identify with  specificity all accounts  subject to backup  withholding
under Section 3406 of the IRC, except for such instances of  non-compliance  and
such  omissions as are not  reasonably  likely to have,  individually  or in the
aggregate, a Material Adverse Effect on NCBC.

                  (f) There has not been an ownership  change, as defined in the
IRC Section  382(g),  of any of the NCBC Companies that occurred during or after
any Taxable  Period in which the Companies  incurred a net  operating  loss that
carries over to any Taxable Period ending after December 31, 1998.

                  (g)  Except  as set  forth  in  Section  5.12(g)  of the  NCBC
Disclosure  Letter,  none of the NCBC Companies is a party to any tax allocation
or  sharing  agreement  and none of the NCBC  Companies  has been a member of an
affiliated  group filing a consolidated  federal income tax return (other than a
group the common parent of which was NCBC) or has any Liability for taxes of any
Person (other than NCBC and its Subsidiaries)  under Treasury Regulation Section
1.1502-6  (or any  similar  provision  of  state,  local  or  foreign  Law) as a
transferee or successor or by contract or otherwise.

                  5.13  Environmental  Matters.  Except as set forth in  Section
5.13 of the NCBC Disclosure Letter:

                  (a) Each NCBC Company, its Participation  Facilities,  and its
Operating  Properties are, and have been, in compliance  with all  Environmental
Laws,   except  for  violations  which  are  not  reasonably   likely  to  have,
individually or in the aggregate, a Material Adverse Effect on NCBC.

                  (b) To the Knowledge of NCBC,  there is no litigation  pending
or threatened before any court,  governmental agency or authority or other forum
in which any NCBC Company or any of its Operating  Properties  or  Participation
Facilities  (or NCBC in  respect of such  Operating  Property  or  Participation
<PAGE>
Facility) has been or, with respect to threatened litigation,  may be named as a
defendant (i) for alleged noncompliance  (including by any predecessor) with any
environmental  law or (ii) relating to the release into the  environment  of any
Hazardous  Material,  whether or not occurring  at, on,  under,  adjacent to, or
affecting (or potentially  affecting) a site owned,  leased,  or operated by any
NCBC Company or any of its  Operating  Properties or  Participation  Facilities,
except for such litigation  pending or threatened that is not reasonably  likely
to have, individually or in the aggregate, a Material Adverse Effect on NCBC.

                  (c) To the  Knowledge  of NCBC,  during  the period of (i) any
NCBC  Company's  ownership  or  operation  of any of  their  respective  current
properties,  (ii) any NCBC  Company's  participation  in the  management  of any
Participation  Facility,  or (iii)  any NCBC  Company's  holding  of a  security
interest in an  Operating  Property,  there have been no  releases of  Hazardous
Material in, on,  under,  adjacent to, or affecting (or  potentially  affecting)
such properties,  except such as are not reasonably likely to have, individually
or in the  aggregate,  a Material  Adverse  Effect on NCBC.  To the Knowledge of
NCBC,  prior to the period of (i) any NCBC  Company's  ownership or operation of
any  of  their   respective   current   properties,   (ii)  any  NCBC  Company's
participation in the management of any Participation Facility, or (iii) any NCBC
Company's holding of a security interest in an Operating Property, there were no
releases of  Hazardous  Material in, on,  under,  or  affecting  such  property,
Participation Facility or Operating Property,  except such as are not reasonably
likely to have,  individually or in the aggregate,  a Material Adverse Effect on
NCBC.

                  5.14 Charter Documents.  NCBC has previously provided, or made
available to, PBI true and correct  copies of the Charter and Bylaws of NCBC, as
amended to date, and each are in full force and effect.

                  5.15 Year 2000 Matters. The computer software operated by NCBC
which is material to the conduct of its  business is capable of  providing or is
being  adapted  to provide  uninterrupted  millennium  functionality  to record,
store,  process and present  calendar dates falling on or after January 1, 2000,
in  substantially  the same  manner  and with  the  same  functionality  as such
software records,  stores, processes and presents such calendar dates falling on
or before December 31, 1999,  except as would not have a Material Adverse Effect
on NCBC.  NCBC has not  received  and does not  expect to  receive a "Year  2000
Deficiency  Notification  Letter"  (as  such  term is  employed  in the  Federal
Reserve's  Supervision  and Regulation  Letter No. SR 98-3(SUP),  dated March 4,
1998).  The costs of the  adaptions and  compliance  referred to in this Section
5.14 are not expected to have a Material Adverse Effect on NCBC.

                                    ARTICLE 6
                    CONDUCT OF BUSINESS PENDING CONSUMMATION

                  6.1  Affirmative  Covenants  of  PBI.  From  the  date of this
Agreement  until the earlier of the Effective  Time or the  termination  of this

and except as otherwise  expressly  contemplated  herein,  PBI shall,  and shall
cause each of its  Subsidiaries  to: (i) operate its business only in the usual,
regular and ordinary course, (ii) preserve intact its business  organization and
assets and maintain its rights and franchises,  (iii) take no action which would
(a) materially  adversely affect the ability of any party to obtain any Consents
required  for the  transactions  contemplated  hereby  without  imposition  of a
<PAGE>
condition or restriction of the type referred to in the last sentence of Section
8.1(b) of this  Agreement  or  prevent  the  transactions  contemplated  hereby,
including  the  Merger,  from  qualifying  for  pooling-of-interests  accounting
treatment or as a reorganization within the meaning of Section 368(a) of the IRC
or (b)  adversely  affect in any  material  respect  the ability of any Party to
perform its covenants and agreements under this Agreement, and (iv) provide NCBC
with PBI financial  statements at the end of each month by the fifteenth  (15th)
day following the close of said month.

                  6.2  Negative   Covenants  of  PBI.   Except  as  specifically
permitted by this  Agreement,  from the date of this Agreement until the earlier
of the Effective Time or the  termination of this  Agreement,  PBI covenants and
agrees  that it will not do or agree  to  commit  to do,  or  permit  any of its
Subsidiaries  to do or agree or commit to do, any of the  following  without the
prior written consent of the chief executive officer, president, chief financial
officer  or  executive  vice  president  of NCBC,  which  consent  shall  not be
unreasonably withheld:

                  (a) Amend the Articles,  Bylaws or other governing instruments
of any PBI Company; or

                  (b) Incur any additional debt  obligation or other  obligation
for  borrowed  money  (other than  indebtedness  of a PBI Company to another PBI
Company)  in excess of an  aggregate  of  $50,000  (for the PBI  Companies  on a
consolidated  basis)  except  in the  ordinary  course  of the  business  of PBI
Subsidiaries  consistent  with past  practices  (which  shall  include,  for PBI
Subsidiaries that are depository institutions,  creation of deposit liabilities,
purchases of federal  funds,  advances from the Federal  Reserve Bank or Federal
Home Loan  Bank,  and entry into  repurchase  agreements  fully  secured by U.S.
government or agency  securities),  or impose,  or suffer the  imposition on any
Asset of any PBI  Company  of any lien or permit  any such lien to exist  (other
than in connection with deposits,  repurchase  agreements,  bankers acceptances,
"treasury tax and loan" accounts established in the ordinary course of business,
advances from the Federal Home Loan Bank, the satisfaction of legal requirements
in the exercise of trust powers,  and Liens in effect as of the date hereof that

PBI Option  Plans),  directly  or  indirectly,  any  shares,  or any  securities
convertible into any shares, of the capital stock of any PBI Company, or declare
or pay any dividend (other than regular quarterly dividends paid consistent with
past practice,  and,  provided the payment  thereof would not prevent the Merger
from being  accounted  for as a  "pooling-of-interests,"  such  other  quarterly
dividend  as is  required to prevent  the PBI Record  Holders  from  foregoing a
dividend  from both PBI and NCBC during any calendar  quarter) or make any other
distribution in respect of PBI capital stock; or

                  (d) Except pursuant to this Agreement or under the PBI Options
Plans, issue, sell, pledge, encumber,  authorize the issuance of, enter into any
contract to issue,  sell,  pledge,  encumber,  or  authorize  the issuance of or
otherwise  permit to become  outstanding,  any  additional  shares of PBI Common

rights, or any option, warrant,  conversion,  or other right to acquire any such

issuance of any other  securities in respect of or in substitution for shares of
PBI Common Stock, or sell, lease,  mortgage or otherwise dispose of or otherwise
encumber  any shares of capital  stock of any PBI  Subsidiary  (unless  any such

any PBI Company as of September  30, 1999  purchase any  securities  or make any
material investment, either by purchase of stock or securities, contributions to
capital, asset transfers,  or purchase of any assets, in any Person other than a

Subsidiary in its fiduciary capacity,  or (iii) the creation of new wholly owned
Subsidiaries  organized to conduct or continue activities otherwise permitted by
this Agreement; or

                  (g) Grant any  increase  in  compensation  or  benefits to the
employees  or  officers  of any PBI  Company,  except  in  accordance  with past
practice disclosed in Section 6.2(g) of the PBI Disclosure Letter or as required
by law; pay any severance or termination  pay or any bonus (other than Christmas
bonuses payable in December 1999 in the ordinary  course of business  consistent
with past practice) other than pursuant to written policies or written contracts
in effect on the date of this  Agreement and disclosed in Section  6.2(g) of the
PBI Disclosure  Letter;  and enter into or amend any severance  agreements  with
officers  of any PBI  Company;  grant  any  material  increase  in fees or other

such  amendment  is  required  by law)  that the PBI  Company  does not have the
unconditional  right to terminate  without  liability  (other than liability for
services already rendered) at any time on or after the Effective Time; or

                  (i)   Except   for  the   contemplated   termination   of  the
Hillsborough Savings Bank, Inc., SSB Employee Stock Ownership Plan in accordance
with the  terms of such plan and  except  for  termination  of the  401(k)  Plan

of any PBI  Company  other than any such change that is required by law or that,
in  the  opinion  of  counsel  is   necessary   or  advisable  to  maintain  the
tax-qualified  status  of any such  plan,  or make any  distributions  from such
employee  benefit  plans,  except as required by law, the terms of such plans or
consistent with past practice; or
<PAGE>
                  (j)  Make  any  significant  change  in any tax or  accounting
methods or systems of internal accounting controls, except as may be appropriate
to conform to changes in tax laws or regulatory accounting requirements or GAAP;
or

                  (k) Commence any litigation  other than in the ordinary course
of business or in accordance with past practice, settle any litigation involving

or restrictions upon the operations of any PBI Company; or

                  (l) Except in the  ordinary  course of  business,  enter into,

or waive, release, compromise or assign any material rights or claims.

                  6.3 Covenants of NCBC.  From the date of this Agreement  until
the earlier of the Effective  Time or the  termination of this  Agreement,  NCBC
covenants  and agrees that it shall (i) continue to conduct its business and the
business of its Subsidiaries in a manner designed in its reasonable  judgment to
enhance the long-term value of the NCBC Common Stock and the business  prospects
of the NCBC  Companies,  and (ii) take no  action  which  would  (a)  materially
adversely  affect the ability of any Party to obtain any  Consents  required for
the  transactions  contemplated  hereby  without  imposition  of a condition  or
restriction  of the type referred to in the last  sentence of Section  8.1(b) of
this Agreement or prevent the transactions  contemplated  hereby,  including the
Merger, from qualifying for  pooling-of-interests  accounting  treatment or as a
reorganization  within the  meaning of IRC  Section  368(a),  or (b)  materially
adversely  affect  the  ability  of any  Party  to  perform  its  covenants  and
agreements under this agreement,  provided, that the foregoing shall not prevent
any  NCBC  Company  from  acquiring  any  other  assets  or  businesses  or from
discontinuing  or  disposing of any of its assets or business if such action is,
in the  judgment of NCBC,  desirable  in the conduct of the business of NCBC and
its  Subsidiaries  and would not,  in the  judgment  of NCBC,  likely  delay the
Effective  Time to a date  subsequent to the date set forth in Section 9.1(e) of
this  Agreement.  Notwithstanding  the foregoing or any other  provision in this
Agreement to the contrary,  nothing herein shall be deemed to restrict NCBC from
exercising  its option  pursuant to the Stock Option  Agreement at any time such
option shall be exercisable.

                  6.4 Adverse  Changes in  Condition.  Each Party agrees to give
written notice promptly to the other Party upon becoming aware of the occurrence
or impending  occurrence of any event or  circumstance  relating to it or any of
its Subsidiaries which (i) is reasonably likely to have,  individually or in the
aggregate,  a Material  Adverse Effect on it or (ii) would cause or constitute a
material breach of any of its representations, warranties or covenants contained
herein,  and to use its reasonable  efforts to prevent or promptly to remedy the
same.

                  6.5 Reports.  Each Party and its  Subsidiaries  shall file all
reports required to be filed by it with Regulatory  Authorities between the date
of this  Agreement and the  Effective  Time and shall deliver to the other Party
copies of all such  reports  promptly  after the same are  filed.  If  financial
statements are contained in any such reports filed with any Regulatory Authority
pursuant to the Securities  Laws, such financial  statements will fairly present
the consolidated  financial  position of the entity filing such statements as of
the dates  indicated  and the  consolidated  results of  operations,  changes in
shareholders'  equity,  and cash flows for the periods then ended in  accordance
<PAGE>
with GAAP or  regulatory  accounting  (subject in the case of interim  financial
statements to normal recurring year-end  adjustments that are not material).  As
of their respective  dates,  such reports filed with any Regulatory  Authorities
pursuant to the  Securities  Laws will comply in all material  respects with the
Securities Laws and will not contain any untrue  statement of a material fact or
omit to state a 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.  Any financial statements contained in any other
reports to another  Regulatory  Authority  shall be prepared in accordance  with
laws applicable to such reports.

                  7.1  Registration  Statement;  Proxy  Statement;   Shareholder

applicable  state Blue Sky or Securities Laws in connection with the issuance of
the shares of NCBC  Common  Stock upon  consummation  of the  Merger.  PBI shall
furnish all  information  concerning  it and the holders of its capital stock as
NCBC may  reasonably  request in connection  with such action.  PBI shall call a
shareholders'  meeting,  to be held as soon as reasonably  practicable after the

voting  upon  approval of this  Agreement  and the Plan of Merger and such other
related matters as its deems  appropriate.  In connection with the shareholders'
meeting,  (i) NCBC and PBI  shall  prepare  a Proxy  Statement  (which  shall be
included  in the  Registration  Statement  with the SEC)  and  mail  such  Proxy
Statement to the  shareholders  of PBI,  (ii) the Parties  shall furnish to each
other  all  information  concerning  them that they may  reasonably  request  in
connection with such Proxy Statement,  (iii) the Board of Directors of PBI shall
recommend  to their  shareholders  the  approval  of the matters  submitted  for
approval,  and (iv) the Board of  Directors  and officers of PBI shall use their
reasonable efforts to obtain such shareholders'  approvals;  provided,  however,
that any such  action by the Board of  Directors  of PBI shall be subject to the
exercise  of  its  good  faith  judgment  as to  its  fiduciary  duties  to  its
shareholders imposed by law.

                  7.2 Exchange Listing. NCBC shall use its reasonable efforts to
list, prior to the Effective Time, on the Nasdaq,  subject to official notice of
issuance,  the shares of NCBC  Common  Stock to be issued to the  holders of PBI

costs,  give all notices,  make all filings,  with the Nasdaq and take all other
actions required in connection with the transactions contemplated herein.

                  7.3  Applications.  NCBC shall prepare and file, and PBI shall
cooperate in the preparation and, where applicable,  filing of applications with
all  Regulatory   Authorities   having   jurisdiction   over  the   transactions
contemplated  by this  Agreement  seeking the  requisite  Consents  necessary to
consummate the  transactions  contemplated by this Agreement.  The Parties shall
deliver to each other  copies of all filings,  correspondence  and orders to and
from,  all  Regulatory   Authorities   in  connection   with  the   transactions
contemplated hereby as soon as practicable upon their becoming available.

<PAGE>
                  7.5  Agreement  as to  Efforts to  Consummate.  Subject to the
terms and conditions of this  Agreement,  each Party agrees to use, and to cause
its  Subsidiaries to use, its reasonable  efforts to take, or cause to be taken,
all actions,  and to do, or cause to be done,  all things  necessary,  proper or
advisable under  applicable  laws to consummate and make  effective,  as soon as
practicable after the date of this Agreement,  the transactions  contemplated by
this Agreement,  including  using its reasonable  efforts to lift or rescind any
order   adversely   affecting  its  ability  to  consummate   the   transactions
contemplated  herein and to cause to be satisfied the conditions  referred to in
Article 8 of this  Agreement;  provided,  however,  that  nothing  herein  shall
preclude  either Party from  exercising  its rights under this  Agreement.  Each
Party shall use, and shall cause each of its Subsidiaries to use, its reasonable
efforts to obtain all Consents  necessary or desirable for the  consummation  of
the transactions contemplated by this Agreement; provided, however, that nothing
in this Section 7.5 shall be  construed  to obligate  NCBC to take any action to
meet any condition required for it to obtain any Consent if such condition would
be  unreasonable  or constitute a significant  impediment upon NCBC's ability to
carry on its business or acquisition programs or to require NCBC to increase its
capital  ratios to amounts in excess of the Federal  Reserve's  minimum  capital
ratio guidelines which may from time to time be in effect.

                  7.6 Investigation and Confidentiality.

                  (a) Prior to the  Effective  Time,  each Party  shall keep the
other Party advised of all material developments relevant to its business and to
consummation  of the Merger and shall permit the other Party to make or cause to
be  made  such  investigation  of the  business  and  properties  of it and  its
Subsidiaries and of their respective financial and legal conditions as the other
Party reasonably requests,  provided that such investigation shall be reasonably
related  to  the  transactions  contemplated  hereby  and  shall  not  interfere
unnecessarily with normal  operations.  No investigation by a Party shall affect
the representations and warranties of the other Party.

                  (b) Each Party shall,  and shall cause its advisers and agents
to, maintain the confidentiality of all confidential information furnished to it
by  the  other  Party  or  its  advisors  or  agents   concerning  its  and  its
Subsidiaries'  businesses,  operations  and financial  positions  (including any
information  learned or obtained during any due diligence  activities) and shall
not  use  such  information  for  any  purpose  except  in  furtherance  of  the
transactions  contemplated  by this  Agreement.  If this Agreement is terminated
prior to the Effective  Time,  each Party shall  promptly  return or certify the
destruction of all documents and copies thereof,  and all work papers containing
confidential  information  received from the other Party.  This agreement  shall
remain in effect and survive termination of this Agreement.

                  (c) PBI shall  use its  reasonable  efforts  to  exercise  its
rights under  confidentiality  agreements  entered  into with persons  which are
considering an Acquisition  Proposal with PBI to preserve the confidentiality of
the  information  relating to PBI provided to such persons and their  Affiliates
and representatives.

                  (d) Each Party  shall give the other  Party  notice as soon as
practicable after any determination by it of any fact or occurrence  relating to
the other Party which it has discovered  through the course of its investigation
and which represents either a material breach of any  representation,  warranty,
covenant  or  agreement  of the other  Party or which  has had or is  reasonably
likely to have a Material Adverse Effect on the other Party.
<PAGE>
                  7.7  Acquisition  Proposals.  PBI  shall  not,  nor  shall  it
authorize or knowingly permit any of its officers, directors or employees or any
investment   banker,   financial   advisor,   attorney,   accountant   or  other
representative retained by it to, initiate, solicit, encourage (including by way
of  furnishing  information),  or take  any  other  action  to  facilitate,  any
inquiries  or the  making of any  proposal  which  constitutes  any  Acquisition
Proposal (as defined below),  or enter into or maintain or continue  discussions
or negotiate with any person in furtherance of an Acquisition Proposal, or agree
to or endorse any Acquisition  Proposal,  and PBI shall (unless it believes such
notification could violate the PBI Board of Directors'  fiduciary duties) notify
NCBC as promptly as practicable,  in reasonable  detail, as to any inquiries and
proposals  which  it or  any of  its  representatives  or  agents  may  receive;
provided,  however, that,  notwithstanding anything to the contrary contained in
this Agreement,  (i) PBI may furnish or cause to be furnished  confidential  and
non-public information  concerning PBI and its businesses,  properties or assets
to a third party,  (ii) PBI may engage in  discussions  or  negotiations  with a
third party,  (iii) following receipt of an Acquisition  Proposal,  PBI may take
and disclose to its  shareholders  information  about the  proposal,  including,
without  limitation,  its position  with respect to such  Acquisition  Proposal,
and/or  (iv)  following  receipt of an  Acquisition  Proposal,  the PBI Board of
Directors may withdraw or modify its  recommendation  of the Merger or terminate
this  Agreement,  but in each event only if and to the extent that the PBI Board
of  Directors  shall  determine  in good faith  based on the  written  advice of
counsel  that such action is required  for the Board of Directors to fulfill its
fiduciary duties to the PBI shareholders.  As used herein, the term "Acquisition
Proposal" means: (x) any acquisition or purchase of a significant  amount of the
assets PBI, or more than 20% of the equity  interest in PBI or any take-over bid
or tender  offer  (including  an issuer bid or self  tender  offer) or  exchange
offer,  consolidation,  plan  or  arrangement,  reorganization,   consolidation,
business  combination,  sale  of  substantially  all  of  the  assets,  sale  of
securities,  recapitalization,  liquidation,  dissolution or similar transaction
involving PBI (other than the  transactions  contemplated  by this Agreement) or
(y) any proposal,  plan or intention to do any of the foregoing  either publicly
announced  or  communicated  to PBI or any  agreement  to  engage  in any of the
foregoing.  The execution of this covenant and the Stock Option Agreement by PBI
constitutes a significant part of the material inducement for NCBC to enter into
this Agreement.

                  7.8 (RESERVED)

                  7.9 Tax Treatment.  Each of the Parties  undertakes and agrees
to use its reasonable  efforts to cause the Merger,  and to take no action which

of IRC Section 368(a) for federal income tax purposes.

                  7.10 State  Takeover  Laws.  Each PBI  Company  shall take any
reasonable  steps  necessary  to exempt the  transactions  contemplated  by this
Agreement from, or if necessary  challenge the validity or  applicability of any
applicable, Takeover Law.

                  7.11 Articles of  Incorporation  Provisions.  Each PBI Company
shall  take all  necessary  action  to  ensure  that the  entering  into of this
Agreement  and the Plan of Merger  and the  consummation  of the  Merger and the
other transactions contemplated hereby and thereby do not and will not result in
the  grant of any  rights to any  Person  under the  Charter,  Bylaws,  or other
governing  instruments of any PBI Company  (other than their rights  pursuant to
this  Agreement and the Plan of Merger and voting and other  similar  rights) or
restrict or impair the ability of NCBC or any of its Subsidiaries to vote, or to
exercise the rights of a shareholder  with respect to, shares of any PBI Company
that may be directly or indirectly acquired or controlled by it.
<PAGE>
                  7.12  Agreement of  Affiliates.  PBI has  disclosed in Section
7.12 of the PBI Disclosure Letter all persons whom it reasonably  believes is an
"affiliate"  of PBI for  purposes of Rule 145 under the 1933 Act.  PBI shall use
its  reasonable  efforts to cause each such  Person to deliver to NCBC not later
than  thirty  (30)  days  prior to the  Effective  Time,  a  written  agreement,
substantially in the form annexed as Exhibit 3 to this Agreement.  NCBC shall be
entitled  to place  restrictive  legends  upon  certificates  for shares of NCBC

purposes of  determining  eligibility  to  participate in and vesting under such
employee  benefit and welfare  plans,  all such officers and employees  shall be
given full  credit for all prior  service as officers  or  employees  of the PBI
Companies,  and no such  officer or  employee  shall be  subject to any  waiting
period  or  pre-existing  condition  limitation  pursuant  to  any  NCBC  health
insurance  plan.  NCBC shall offer  employment  contracts in the form annexed as

employed  through the Effective Date but whose  employment is terminated by NCBC
or any of its  Subsidiaries  within 90 days after the Effective  Date shall,  in
addition  to any  benefits  to which such  employee  may be  entitled  under the
existing  Severance  Plan of the Savings  Bank  Subsidiary,  be paid a retention
bonus  equal  to  four  (4)  weeks  salary.  Any  employee  of PBI or any of its
Subsidiaries  who remains  employed  through the Effective  Date and who remains
employed by PBI, any of its Subsidiaries or any of their successors for at least
ninety (90) days after the Effective Date shall be paid a retention  bonus equal

                  7.14 Advisory Board;  Emeritus Directors.  For a period of two
(2) years from and after the Effective  Time,  NCBC shall cause the Savings Bank
Subsidiary  to maintain an advisory  board of directors  consisting  of nine (9)
persons, each of whom shall be entitled to attend all regular quarterly meetings
of the Board of  Directors  of the Savings  Bank  Subsidiary,  but shall nave no
right to vote as a director.  Each advisory director shall be paid a retainer of
$1,000  every six  months and a director  fee of $500 for each  regular  meeting
attended  in  person.  In  addition  to the  foregoing,  existing  PBI  emeritus
directors  shall be appointed to serve on such advisory  board for an annual fee
of $3,111. In consideration of the foregoing and the provisions of Section 7.18,
PBI shall use its reasonable  best efforts to cause each director of PBI and the

the form annexed as Exhibit 6 to this Agreement.

                  7.15 D&O Coverage.  At the Effective  Time, NCBC will provide,

<PAGE>
                  7.16 Indemnification.

                  (a) With  respect to all claims  brought  during the period of
six (6) years after the Effective  Time, NCBC shall  indemnify,  defend and hold
harmless present and former directors, officers, employees and agents of PBI and
PBI Companies (the "PBI Entities") (each an "Indemnification Party") against all
Liabilities  arising out of actions or omissions  arising out of the Indemnified
Party's service or services as directors, officers, employees or agents of a PBI
Entity, or at the request of a PBI Entity, of another corporation,  partnership,
joint venture,  trust or other enterprise occurring at or prior to the Effective
Time  (including  transactions  contemplated  by this  Agreement) to the fullest
extent permitted under North Carolina Law and the Articles of Incorporation  and
Bylaws of PBI as in effect on the date hereof,  including provisions relating to
advances of expenses  incurred in the defense of any  Litigation  and whether or
not any PBI Entity or NCBC is insured against any such matter.  Without limiting
the  foregoing,  in any case in which  approval by the Surviving  Corporation is
required to effectuate  any  indemnification,  the Surviving  Corporation  shall
direct, at the election of the Indemnified  Party, that the determination of any
such approval shall be made by independent  counsel mutually agreed upon between
NCBC and the Indemnified Party.

                  (b) Any  Indemnified  Party  wishing to claim  indemnification
under paragraph (a) of this Section 7.16, upon learning of any such Liability or
Litigation,  shall  promptly  notify  NCBC  thereof.  In the  event  of any such
Litigation  (whether  arising  before  or after  the  Effective  Time),  (i) the
Surviving Corporation shall have the right to assume the defense thereof and the
Surviving  Corporation  shall not be liable to such Indemnified  Parties for any
legal expenses of other counsel or any other expenses  subsequently  incurred by
such Indemnified Parties in connection with the defense thereof,  except that if
the Surviving  Corporation  elects not to assume such defense or counsel for the
Indemnified  Parties shall advise that there are substantive  issues which raise
conflicts of interest  between the  Surviving  Corporation  and the  Indemnified
Parties,  the Indemnified  Parties may retain counsel  satisfactory to them, and
the Surviving  Corporation shall be obligated  pursuant to this paragraph (b) to
pay  for  only  one  firm  of  counsel  for  all  Indemnified   Parties  in  any
jurisdiction,  (ii) the Indemnified Parties will cooperate in the defense of any
such Litigation, and (iii) the Surviving Corporation shall not be liable for any
settlement effected without its prior written consent; and provided further that
the  Surviving  Corporation  shall  not have any  obligation  thereunder  to any
Indemnified Party when and if a court of competent jurisdiction shall determine,
and such determination shall have become final, that the indemnification of such
Indemnified Party in the manner  contemplated hereby is prohibited by applicable
law.

                  The  indemnification  provided  herein shall be in addition to
any  idemnification  rights  on  indemnitee  may  have by law,  pursuant  to the
Articles  of  Incorporation  or by  laws  of PBI or any of its  subsidiaries  or
pursuant  to the terms of any  employee  benefit  plan for which the  indemnitee
serves as a fiduciary.

                  7.17 PBI  Severance  Plan.  NCBC agrees that the Merger  shall
constitute  a "Change in  Control"  for  purposes of the  existing  Hillsborough
Savings Bank, Inc., SSB Severance Plan. The benefits provided by such Plan shall
survive the Closing and no subsequent  amendment or  termination of such Plan by
NCBC or its  Subsidiaries  shall affect the rights of employees  with respect to
the receipt of benefits under such Plan.
<PAGE>
                  7.18 Director's  Deferred  Compensation  Plan. For a period of
two (2) years  after the  Effective  Time,  NCBC shall  cause the  Savings  Bank
Subsidiary to maintain the current Director's Deferred  Compensation Plan and to
permit  continued  deferral of  directors'  retainers  and fees by advisory  and
emeritus  directors.  After the end of such period, no additional  contributions
shall be made to such plan,  and accrued  balances  (plus any earnings  thereon)
shall be paid in accordance with the terms of such plan.

                CONDITIONS PRECEDENT TO OBLIGATIONS TO CONSUMMATE

                  8.1 Conditions to  Obligations  of Each Party.  The respective
obligations  of each Party to perform this  Agreement and  consummate the Merger
and the other transactions  contemplated  hereby are subject to the satisfaction
of the following  conditions,  unless waived by both Parties pursuant to Section
10.6 of this Agreement:

                  (a) Shareholder Approvals.  The shareholders of PBI shall have
approved  this  Agreement  and the Plan of Merger  and the  consummation  of the
transactions  contemplated  hereby and thereby,  including the Merger, as and to
the extent required by law or by the provisions of any governing instruments.

                  (b)  Regulatory  Approvals.   All  Consents  of,  filings  and
registrations  with, and notifications to, all Regulatory  Authorities  required
for  consummation of the Merger shall have been obtained or made and shall be in
full  force and  effect  and all  waiting  periods  required  by law shall  have
expired. No Consent obtained from any Regulatory Authority which is necessary to
consummate  the  transactions   contemplated  hereby  shall  be  conditioned  or
restricted  in a  manner,  which  in the  reasonable  judgment  of the  Board of
Directors of either party would so materially  adversely impact the financial or
economic  benefits of the transactions  contemplated by this Agreement that, had
such  condition  or  requirement  been  known,  either  party  would not, in its
reasonable judgment, have entered into this Agreement.

                  (c)  Consents.  Each  Party  shall have  obtained  any and all
Consents  required for  consummation of the Merger (other than those referred to
in Section 8.1(b) of this  Agreement) or for the preventing of any default under
any  contract  or  permit of such  Party  which,  if not  obtained  or made,  is
reasonably likely to have,  individually or in the aggregate, a Material Adverse
Effect on such Party.

                  (d) Legal  Proceedings.  No court or  government or regulatory
authority of competent  jurisdiction  shall have enacted,  issued,  promulgated,
enforced  or  entered  any  law or  order  (whether  temporary,  preliminary  or
permanent) or taken any other action which prohibits, restricts or makes illegal
consummation of the transactions  contemplated by this Agreement and the Plan of
Merger.

                  (e) Registration  Statement.  The Registration Statement shall
be effective under the 1933 Act, no stop orders  suspending the effectiveness of
the Registration  Statement shall have been issued, no action, suit,  proceeding
or investigation by the SEC to suspend the effectiveness thereof shall have been
initiated and be continuing,  and all necessary  approval under state securities
laws or the 1933 Act,  or 1934 Act  relating  to the  issuance or trading of the
shares of NCBC Common Stock pursuant to the Merger shall have been received.
<PAGE>
                  (f) Exchange Listing. The shares of NCBC Common Stock issuable
pursuant to the Merger  (including any shares issued to satisfy options existing
under the PBI Option  Plans) shall have been approved for listing on the Nasdaq,
subject to official notice of issuance.


                  (g) Tax Opinion.  NCBC and PBI shall have  received an opinion
of Bass,  Berry & Sims PLC,  counsel to NCBC,  dated the  Closing  Date,  to the
effect that (a) the Merger constitutes a reorganization  under Section 368(a) of
the IRC, and (b) no gain or loss will be recognized by  shareholders  of PBI who
receive  shares of NCBC Common  Stock in exchange for their shares of PBI Common
Stock, except that gain or loss may be recognized as to cash received in lieu of
fractional share interests; in rendering their opinion, such counsel may require
and rely upon  representations  and  agreements,  including  those  contained in
certificates of officers of PBI, NCBC and others.

(h) Pooling of Interests.  NCBC shall have received a negative  assurance letter
from KPMG LLP, PBI's independent certified public accountant's dated the Closing
Date,  to the effect that such firm is aware of no matters  relating to PBI that
would  prevent PBI from  entering  into a  transaction  similar to the  proposed
transaction  that would qualify for  pooling-of-interests  accounting  treatment
based upon the attributes of PBI only.

                  8.2 Conditions to Obligations of NCBC. The obligations of NCBC
to perform this Agreement and  consummate the Merger and the other  transactions
contemplated hereby are subject to the satisfaction of the following conditions,
unless waived by NCBC pursuant to Section 10.6(a) of this Agreement:

                  (a)  Representations  and  Warranties.  For  purposes  of this
Section 8.2(a),  the accuracy of the  representations  and warranties of PBI set
forth in this  Agreement  shall be assessed as of the date of this Agreement and
as of the Effective Time with the same effect as though all such representations
and  warranties  had been made on and as of the Effective  Time  (provided  that
representations  and  warranties  which are  confined to a specified  date shall
speak only as of such date). The representations and warranties of PBI set forth
in  Section  4.3 of  this  Agreement  shall  be true  and  correct  (except  for
inaccuracies which are de minimis in amount). The representations and warranties
of PBI set forth in Sections 4.20, 4.21 and 4.22 of this Agreement shall be true
and correct in all material respects.  There shall not exist inaccuracies in the
representations and warranties of PBI set forth in this Agreement (including the
representations  and warranties set forth in Sections 4.3, 4.20,  4.21 and 4.22)
such that the aggregate effect of such inaccuracies has, or is reasonably likely
to have, a Material Adverse Effect on PBI.

                  (b)  Performance of Agreements and Covenants.  Each and all of
the  agreements  and covenants of PBI to be performed and complied with pursuant
to this  Agreement  and the other  agreements  contemplated  hereby prior to the
Effective  Time shall have been duly performed and complied with in all material
respects.

                  (c)  Certificates.  PBI  shall  have  delivered  to NCBC (i) a
certificate,  dated as of the  Effective  Time and  signed on its  behalf by its
president and the chief financial officer of the Savings Bank Subsidiary, to the
effect that the conditions of its  obligations  set forth in Sections 8.2(a) and
8.2(b) of this  Agreement  have been  satisfied,  and (ii)  certified  copies of
resolutions duly adopted by PBI's Board of Directors and shareholders evidencing
the  taking of all  corporate  action  necessary  to  authorize  the  execution,
delivery  and  performance  of this  Agreement  and the Plan of Merger,  and the
consummation of the transactions  contemplated  hereby and thereby,  all in such
reasonable detail as NCBC and its counsel shall reasonably request.
<PAGE>
                  (d) Affiliates Agreements.  NCBC shall have received from each
affiliate  of PBI the  affiliates  letter  referred  to in Section  7.12 of this
Agreement,  to the extent necessary to assure in the reasonable judgment of NCBC
that the transactions  contemplated hereby will qualify for pooling-of-interests
accounting treatment.

                  (e) Legal Opinion. PBI shall have delivered to NCBC an opinion
of Brooks, Pierce, McLendon,  Humphrey Leonard, L.L.P., counsel to PBI, dated as
of the Closing  Date,  addressed to and in form and  substance  satisfactory  to

acceleration  under  any  mortgage,   agreement,   lease,  indenture,  or  other

validly authorized,  executed and delivered on behalf of NCBC by duly authorized

obligation  of  PBI)  constitutes  a  valid  and  binding   obligation  of  NCBC
enforceable  in  accordance  with its  terms,  subject as to  enforceability  to

                  (iv) The  execution  and delivery by NCBC of the  Agreement do
not, and if NCBC were now to perform its  obligations  under the Agreement  such
performance  would not,  violate or  contravene  any provision of the Charter or
Bylaws  of  NCBC  or,  to  such  counsel's  actual  knowledge  but  without  any
independent  investigation,  result in any breach of, or default or acceleration
under any mortgage,  agreement,  lease, indenture,  or other instrument,  order,
judgment or decree to which NCBC is a party or by which it is bound.

                  (e) Fairness  Opinion.  PBI shall have  received  from Trident

that the Merger shall not have been  consummated  by September  30, 2000, if the
failure to consummate  the  transactions  contemplated  hereby on or before such

filed all  applications  necessary to obtain the  necessary  Consents of banking
Regulatory  Authorities  within sixty (60) days of the date  hereof,  and if the

this  Agreement  shall  survive any such  termination  and  abandonment;  (ii) a
termination  pursuant to  Sections  9.1(b),  9.1(c) or 9.1(f) of this  Agreement

termination;  and (iii) Section 7.8 of this  Agreement  shall be governed by its

             MANNER OF CONVERTING SHARES AND OPTIONS; EXCHANGE RATIO

                  2.1 Conversion,  Cancellation and Exchange of Shares; Exchange
Ratio.  At the Effective  Time, by virtue of the Merger  becoming  effective and
without any action on the part of NCBC,  PBI, or the  shareholders of any of the
foregoing,  the shares of the  constituent  corporations  shall be  converted as
follows:
<PAGE>
                  (a) NCBC Common Stock.  Each share of NCBC common  stock,  par
value  $2.00  per  share  (the  "NCBC  Common  Stock")  issued  and  outstanding
immediately prior to the Effective Time shall remain issued and outstanding from
and after the Effective Time.

                  (b) PBI Common Stock.  Each share of PBI common stock,  no par
value (the "PBI Common  Stock")  issued and  outstanding  at the Effective  Time
shall cease to represent any interest (equity,  shareholder or otherwise) in PBI
and shall  automatically be converted  exclusively into, and constitute only the
right of each  holder of record  of PBI  Common  Stock  immediately  before  the
Effective  Time (a "PBI  Record  Holder")  to receive in  exchange  for such PBI
Record  Holder's shares of PBI Common Stock the  consideration  to which the PBI
Record   Holder  is  entitled  as   provided   in  this   Section   2.1(b)  (the
"Consideration"):

                         (i) The  Exchange  Ratio  Calculation.  Subject  to any
adjustments   which  may  be  required  by  an  event  described  in  Subsection
2.1(b)(iii) below, at and as of the Effective Time:


                            (A) Each share of the PBI Common  Stock  outstanding
                      at and as of the  Effective  Time shall be converted  into
                      the right to receive  that number of shares of NCBC Common
                      Stock equal to (the "Exchange Ratio"):

                                 (I)  The  quotient  of the Net  Purchase  Price
                         (defined  below)  divided by the NCBC Market  Price Per
                         Share (defined below),

                                      divided by

                                 (II) The sum of the  number  of  shares  of PBI
                         Common  Stock  outstanding  at and as of the  Effective
                         Time and the  number  of  shares  of PBI  Common  Stock
                         issuable  pursuant  to options to  purchase  PBI Common
                         Stock to the extent that such  options are  outstanding
                         at and as of the Effective Time.

                  Notwithstanding the provisions of subsection (A) above, if the
Market Price Per Share shall be less than $20.70,  then each share of PBI Common
Stock  outstanding  at and as of the Effective  Time shall be converted into the
right to receive .60499 shares of NCBC Common Stock, and if the Market Price Per
Share shall exceed  $25.30,  then each share of PBI Common Stock  outstanding at
and as of the Effective Time shall be converted into the right to receive .49499
shares of NCBC Common Stock.

                                 (B) "Net Purchase  Price" shall be $34,500,000.
                            No share of PBI Common  Stock  shall be deemed to be
                            outstanding  or have any rights other than those set
                            forth in this  Section  2.1(b)  after the  Effective
                            Time.  No  fractional  shares of NCBC  Common  Stock
                            shall  be  issued  in  the  Merger   and,  if  after
                            aggregating  all of the whole and fractional  shares
                            of NCBC  Common  Stock to which a PBI Record  Holder
                            shall be  entitled  based upon this  Exchange  Ratio
<PAGE>
                            calculation,  there should be a fractional  share of
                            NCBC Common Stock  remaining,  such fractional share
                            shall be settled by a cash payment therefor pursuant
                            to  Article 3 of this  Plan of  Merger,  which  cash
                            settlement  shall be based upon the Market Price Per
                            Share (as  defined  below) of one (1) full  share of
                            NCBC Common Stock.

                  (ii)  Definition of Market Price Per Share.  The "Market Price
Per Share" of NCBC Common  Stock  shall be the average of the closing  price per
share of NCBC Common  Stock on the Nasdaq  Stock  Market's  National  Market (as
reported by The Wall Street  Journal) on the five (5) trading day period  ending
two (2) trading days prior to the Effective Time, or such earlier date as may be
required by the Securities and Exchange Commission.

                  (iii) Effect of Stock  Splits,  Reverse  Stock  Splits,  Stock
Dividends and Similar Changes in the Capital of PBI. Should PBI effect any stock
splits,  reverse  stock  splits,  stock  dividends  or  similar  changes  in its
respective capital accounts prior to the
Effective Time, the Exchange Ratio may, in NCBC's sole discretion if such change
in the capital  accounts  constitutes a breach of any of PBI's  representations,
warranties or covenants,  be adjusted in such a manner as the Board of Directors
of NCBC  shall  deem in good  faith to be fair and  reasonable  in order to give
effect  to  such  changes.   Notwithstanding  the  foregoing,  nothing  in  this
subparagraph  (iii)  shall be  deemed to be a waiver  of the  inaccuracy  of any
representation  or  warranty  or breach of any  covenant by PBI set forth in the
Merger Agreement.

                  (c)  Shares  Held by PBI or NCBC.  Each of the  shares  of PBI
Common Stock held by PBI or any subsidiary or affiliate of PBI or by NCBC or any
subsidiary or affiliate of NCBC, in each case other than in a fiduciary capacity
or as a result of debts previously contracted, shall be cancelled and retired at
the Effective Time and no Consideration shall be issued in exchange therefor.

                  2.2 Conversion of Stock Options.

                  (a) At the  Effective  Time,  all rights  with  respect to PBI
Common Stock pursuant to stock options ("PBI Options")  granted by PBI under all
stock option plans of PBI (each a "PBI Option Plan"),  which are  outstanding at
the Effective  Time,  whether or not  exercisable,  shall be converted  into and
become rights with respect to NCBC Common Stock,  and NCBC shall assume each PBI
Option,  in  accordance  with the terms of the PBI Option Plan and stock  option
agreement by which it is evidenced.  From and after the Effective Time, (i) each
PBI Option  assumed by NCBC may be  exercised  solely for shares of NCBC  Common
Stock, (ii) the number of shares of NCBC Common Stock subject to such PBI Option
shall be equal to the number of shares of PBI Common  Stock  subject to such PBI
Option immediately prior to the Effective Time multiplied by the Exchange Ratio,
and (iii) the per share  exercise  price  under  each such PBI  Option  shall be
adjusted by dividing the per share  exercise price under each such PBI Option by
the Exchange Ratio and rounding down to the nearest cent. PBI agrees to take all
necessary  steps to  effectuate  the  foregoing  provisions of this Section 2.2.
Notwithstanding  the foregoing,  each stock option which is an "incentive  stock
option"  under the PBI Option  Plan shall be adjusted as required by Section 424
of the  Internal  Revenue  Code  of  1986,  as  amended  (the  "Code")  and  the
regulations  promulgated  thereunder  so as to  continue as an  incentive  stock
option under Section 424 of the Code and so as not to constitute a modification,
extension or renewal of the option  within the meaning of Section  424(h) of the
Code.
<PAGE>
                  2.3 Restricted Stock. At the Effective Time, each share of PBI
Common Stock held by the trustees under the Hillsborough Savings Bank, Inc., SSB
Management  Recognition Plan (the "MRP"),  including  unvested shares subject to
Awards as defined in the MRP heretofore  granted to participants  under the MRP,
shall be converted  into and exchanged for NCBC Common Stock and cash in lieu of
fractional  shares  pursuant to the  provisions  of Section 3.1 below,  and such
shares and cash  shall  thereafter  be held to be  delivered  to the  respective
participants  pursuant to the MRP. At the Effective Time, the MRP and each stock
grant  agreement  pursuant to which Awards were granted  shall remain in effect,
except that from and after the Effective  Time the MRP and each such stock grant
agreement  shall be amended as  necessary  to  provide  that:  (i) NCBC shall be
substituted  for the  Hillsborough  Savings Bank,  Inc.,  SSB; (ii) the Board of
Directors of NCBC or its  Compensation  Committee  shall be substituted  for the
Committee of the Savings  Bank  Subsidiary  Board of  Directors  with respect to
administration  of the MRP; (iii) unvested  shares of NCBC Common Stock and cash
determined  in  accordance  with the  provisions  of Section  3.1 below shall be
substituted  for unvested  shares of PBI Common  Stock;  (iv) no shares or other
assets in addition to the shares of PBI Common Stock currently awarded under the
MRP  shall  be  purchased  by or for the  MRP;  and (v)  shares,  cash or  other
interests in the MRP forfeited by participants shall be retained by the trustees
of the MRP and shall be available for making additional Awards under the MRP.

                  2.4  Anti-Dilution  Provisions.  In the event NCBC changes the
number  of shares of NCBC  Common  Stock  issued  and  outstanding  prior to the
Effective Time as a result of a stock split, stock dividend, or recapitalization
with respect to such stock and the record date  therefor (in the case of a stock
dividend) or the effective date thereof (in the case of a stock split or similar
recapitalization  for which a record date is not established)  shall be prior to
the Effective Time, the Exchange Ratio shall be proportionately adjusted.

                                    ARTICLE 3
                               EXCHANGE OF SHARES

                  3.1 Exchange  Procedures.  Promptly after the Effective  Time,
NCBC and PBI shall cause the Bank of New York (the "Exchange  Agent") to mail to
the PBI Record Holders  appropriate  transmittal  materials (which shall specify
that delivery shall be effected,  and risk of loss and title to the certificates
theretofore representing shares of PBI Common Stock shall pass, only upon proper
delivery of such  certificates  to the Exchange  Agent).  The Exchange Agent may
establish  reasonable and customary  rules and procedures in connection with its
duties.  After the  Effective  Time,  each PBI Record Holder of PBI Common Stock
(other than shares to be  cancelled  pursuant to Section  2.1(c) of this Plan of
Merger)  issued  and  outstanding  at the  Effective  Time shall  surrender  the
certificate or certificates  representing  such shares to the Exchange Agent and
shall  promptly  upon  surrender   thereof  receive  in  exchange  therefor  the
Consideration  provided in Section 2.1(b) of this Plan of Merger,  together with
all undelivered  dividends or  distributions  in respect of such shares (without
interest  thereon) pursuant to Section 3.2 of this Plan of Merger. To the extent
required by Section  2.1(b) of this Plan of Merger,  each PBI Record Holder also
shall receive,  upon surrender of the certificate or  certificates  representing
his or her  shares of PBI  Common  Stock  outstanding  immediately  prior to the
Effective  Time,  cash in lieu of any  fractional  share of NCBC Common Stock to
which such holder may be otherwise entitled (without  interest).  NCBC shall not
be  obligated  to deliver the  Consideration  to which any PBI Record  Holder is
entitled as a result of the Merger until such PBI Record Holder  surrenders such
holder's certificate or certificates representing the shares of PBI Common Stock
<PAGE>
for exchange as provided in this Section 3.1. The certificate or certificates of
PBI Common Stock so surrendered shall be duly endorsed as the Exchange Agent may
reasonably require. Any other provision of this Plan of Merger  notwithstanding,
neither NCBC nor the Exchange  Agent shall be liable to a PBI Record  Holder for
any  amounts  paid or  properly  delivered  in good  faith to a public  official
pursuant  to any  applicable  abandoned  property  Law.  Adoption  of the Merger
Agreement and this Plan of Merger by the  shareholders  of PBI shall  constitute
ratification of the appointment of the Exchange Agent.

                  3.2  Rights of Former  PBI Record  Holders.  At the  Effective
Time,  the stock  transfer  books of PBI shall be  closed as to  holders  of PBI
Common  Stock  outstanding  immediately  prior  to the  Effective  Time,  and no
transfer of PBI Common Stock by any PBI Record  Holder shall  thereafter be made
or recognized.  Until surrendered for exchange in accordance with the provisions
of Section 3.1 of this Plan of Merger, each certificate theretofore representing
shares of PBI Common  Stock  (other  than  shares to be  cancelled  pursuant  to
Section  2.1(c) of this Plan of Merger) shall from and after the Effective  Time
represent for all purposes only the right to receive the Consideration  provided
in Section  2.1(b) of this Plan of Merger,  subject,  however,  to the Surviving
Corporation's  obligation to pay any  dividends or make any other  distributions
with a record date prior to the Effective  Time which have been declared or made
by PBI in respect  of such  shares of PBI Common  Stock in  accordance  with the
terms of this Plan of Merger  and which  remain  unpaid at the  Effective  Time.
Whenever a dividend or other distribution is declared by NCBC on the NCBC Common
Stock,  the  record  date for  which  is at or after  the  Effective  Time,  the
declaration shall include dividends or other distributions on all shares of NCBC
Common Stock issuable pursuant to this Plan of Merger,  but beginning sixty (60)
days after the Effective Time no dividend or other  distribution  payable to the
holders  of  record  of NCBC  Common  Stock  as of any  time  subsequent  to the
Effective  Time shall be delivered to a PBI Record  Holder until such PBI Record
Holder  surrenders his or her certificate or certificates  evidencing PBI Common
Stock for  exchange as provided in Section 3.1 of this Plan of Merger.  However,
upon surrender of such PBI Common Stock certificate,  both the NCBC Common Stock
certificate and any undelivered  dividends and cash payments  payable  hereunder
(without  interest)  shall be  delivered  and paid with  respect  to each  share
represented by such certificate.

                  3.3 Lost Certificates. Any PBI Record Holder whose certificate
representing  shares of PBI  Common  Stock has been lost,  destroyed,  stolen or
otherwise is missing shall be entitled to receive a certificate representing the
shares of NCBC Common Stock and cash in lieu of fractional shares to which he or
she  is  entitled  in  accordance  with  and  upon  compliance  with  conditions
reasonably  imposed by the Exchange  Agent  (including,  without  limitation,  a
requirement that the shareholder  provide a lost  instruments  indemnity bond in
form, substance and amount reasonably satisfactory to the Exchange Agent).

                                  MISCELLANEOUS

                  4.1 Conditions  Precedent.  Consummation of the Merger by NCBC
shall be conditioned on the  satisfaction of or waiver by NCBC of the conditions
precedent  to the  Merger  set  forth  in  Sections  8.1 and  8.2 of the  Merger
Agreement.  Consummation  of the  Merger  by PBI  shall  be  conditioned  on the
satisfaction,  or waiver by PBI, of the  conditions  precedent to the Merger set
forth in Sections 8.1 and 8.3 of the Merger Agreement.

                  4.2 Amendments.  To the extent permitted by Law and the Merger
Agreement,  this  Plan of Merger  may be  amended  as  permitted  in the  Merger
Agreement.

                             STOCK OPTION AGREEMENT

                  This  STOCK  OPTION  AGREEMENT  ("Agreement"),   dated  as  of
December 27, 1999,  is between  NATIONAL  COMMERCE  BANCORPORATION  ("NCBC") and
PIEDMONT BANCORP, INC. ("PBI").

                                    RECITALS

                  PBI  and  NCBC  have   executed  an  Agreement   and  Plan  of
Reorganization  ("Merger  Agreement"),  of even date with this Agreement,  under
which  PBI will be  merged  with and into NCBC  upon  completion  of the  merger
("Merger") contemplated in the Merger Agreement.

                  By  negotiating  and  executing  the Merger  Agreement  and by
taking actions necessary or appropriate to effect the transactions  contemplated
by the Merger Agreement, NCBC has incurred and will incur substantial direct and
indirect  costs  (including,  without  limitation,  the costs of management  and
employee time) and will forgo the pursuit of certain alternative investments and
transactions.

                                    AGREEMENT

                  THEREFORE,  in consideration of the promises set forth in this
Agreement and in the Merger Agreement, the parties agree as follows:

                  1. Grant of Option.  Subject to the terms and  conditions  set
forth in this Agreement,  PBI irrevocably grants an option ("Option") to NCBC to
purchase that number of authorized but unissued shares of PBI's common stock, no
par value per share ("PBI Common Stock"),  such that immediately  following such
purchase  NCBC  would own 19.5% of the then  issued and  outstanding  shares (as
adjusted as set forth  herein) of PBI Common  Stock after  giving  effect to the
exercise  of the Option at a per share price in cash (or  immediately  available
funds) equal to $7.65 ("Option Price").

                  2.  Exercise  of  Option.  Subject to the  provisions  of this
Section 2 and of Section 12(a) of this  Agreement,  this Option may be exercised
by NCBC as set forth in Section 5 of this Agreement, in whole or in part, at any
time, in any of the following circumstances:

                  (a) PBI enters into an  agreement  or PBI's Board of Directors
recommends to PBI shareholders (or withdraws its  recommendation FOR approval of
the  Merger  after  receipt of a proposal  for PBI to enter  into) an  agreement
(other than the Merger Agreement) under which any entity,
person or group (collectively "Person"),  within the meaning of Section 13(d)(3)
of the Securities  Exchange Act of 1934, as amended ("Exchange Act"), would: (1)
merge or consolidate with,  acquire 25% or more of the assets or liabilities of,
or enter into any similar  transaction  with PBI, or (2)  purchase or  otherwise
acquire (including by merger, reorganization,  consolidation,  share exchange or
any similar  transaction)  securities  representing  25% or more of PBI's voting
shares;

                  (b) any Person  (other  than NCBC or any of its  subsidiaries)
acquires the beneficial  ownership or the right to acquire beneficial  ownership
of securities  which,  when aggregated with other such securities  owned by such
Person, represents 25% or more of the voting shares of PBI (the term "beneficial
ownership"  for purposes of this  Agreement has the meaning set forth in Section
13(d) of the Exchange Act, and the  regulations  promulgated  under the Exchange
<PAGE>
Act) (not  including  acquisitions  pursuant to which the  acquiror or acquiring
group has successfully rebutted the presumption of control pursuant to 12 C.F.R.
ss.574(e) and has voted or given to management  of PBI an  irrevocable  proxy to
vote the  securities  so acquired  for the approval of the Merger at any and all
meetings of  shareholders of PBI called for that purpose or at which such matter
is considered (a "Rebuttal Acquisition");

                  (c)  failure  of the  shareholders  to  approve,  prior to the
termination of the Merger Agreement, the Merger by the required affirmative vote
at a meeting of the  shareholders,  because a third Person (other than NCBC or a
subsidiary of NCBC) announces  publicly or  communicates,  in writing,  to PBI a
proposal  to (a)  acquire PBI (by  merger,  reorganization,  consolidation,  the
purchase  of 25% or more of its  assets or  liabilities,  or any  other  similar
transaction),  or (b) purchase or otherwise acquire securities  representing 25%
or more of the voting shares of PBI.

                  (d) It is  understood  and agreed  that the Option will become
exercisable  immediately  upon  the  occurrence  of any  of the  above-described
circumstances  even though the circumstance  occurred as a result, in part or in
whole, of the board of PBI complying with its fiduciary duties.

                  (e)  Notwithstanding  any other provision of this Agreement to
the contrary, in no event shall:

                                    (i) NCBC's Total  Profit (as defined  below)
                  exceed  $1,035,000  and,  if it  otherwise  would  exceed such
                  amount, NCBC at its sole election, shall either (A) reduce any
                  remaining  shares of PBI Common  Stock  subject to the Option,
                  (B)  deliver  to PBI for  cancellation  without  consideration
                  shares  of PBI  Common  Stock  previously  purchased  by  NCBC
                  pursuant to the  exercise of the Option,  (C) pay cash to PBI,
                  or (D) any combination of the foregoing, so that NCBC's actual
                  realized Total Profit shall not exceed $1,035,000 after taking
                  into account the foregoing actions; or

                                    (ii) the Option be exercised for a number of
                  shares  of PBI  Common  Stock  as  would,  as of the  date  of
                  exercise,  result in NCBC's Total Notional  Profit (as defined
                  below) exceeding  $1,035,000;  provided,  that nothing in this
                  clause  (ii)  shall   restrict  any  exercise  of  the  Option
                  permitted hereby on any subsequent date.

                  As used in this Agreement,  the term "Total Profit" shall mean
the aggregate sum (prior to the payment of taxes) of the following:  (i) any net
cash amounts received by NCBC pursuant to the sale of shares of PBI Common Stock
received  pursuant to the exercise of the Option ( or any other  securities into
which such shares shall be converted or  exchanged) to any  unaffiliated  person
less NCBC's  purchase  price of such  shares;  (ii) any amount  received by NCBC
pursuant to PBI's repurchase of shares of PBI Common Stock received  pursuant to
the exercise of the Option less NCBC's purchase price of such shares,  and (iii)
any amount  received by NCBC pursuant to PBI's  repurchase of the Option (or any
portion thereof).
<PAGE>
                  As used in this Agreement,  the term "Total  Notional  Profit"
with  respect to any  number of shares of PBI Common  Stock as to which NCBC may
propose to exercise the Option shall be the Total  Profit  determined  as of the
date of such proposed exercise,  assuming that the Option were exercised on such
date for such number of shares and assuming that such shares,  together with all
other  such  shares  held by NCBC or its  affiliates  as of such  date that were
issued pursuant to the exercise of the Option, were sold for cash at the closing
sale  price  per share of PBI  Common  Stock as  quoted  on the  American  Stock
Exchange  ("AMEX")  or, if PBI  Common  Stock in not then  quoted  on AMEX,  the
highest  bid  price  per share as  quoted  on the  principal  trading  market or
securities  exchange on which such shares are traded as reported by a recognized
source chosen by NCBC as of the close of business on the  preceding  trading day
(less customary brokerage commissions).

                  3.  Notice,  Time and Place of  Exercise.  When NCBC wishes to
exercise the Option,  NCBC will give written notice of its intention to exercise
the Option and the place and date for the  closing of the  exercise  (which date
may not be later than ten business days from the date such notice is mailed). If
any law,  regulation  or other  restriction  will not permit such exercise to be
consummated  during  this  ten-day  period,  the  date for the  closing  of such
exercise will be within five days following the cessation of the  restriction on
consummation.

                  4. Payment and Delivery of Certificate(s).  At the closing for
the  exercise of the Option or any portion  thereof,  (a) NCBC and PBI will each
deliver to the other certificates as to the accuracy, as of the closing date, of
their respective  representations and warranties under this Agreement,  (b) NCBC
will pay the aggregate  purchase  price for the shares of PBI Common Stock to be
purchased  by delivery of a certified  or bank  cashier's  check in  immediately
available  funds payable to the order of PBI, and (c) PBI will deliver to NCBC a
certificate or certificates representing the shares so purchased.

                  5.  Transferability of the Option.  Neither the Option nor any
portion of the Option will be transferable  except to a wholly-owned  subsidiary
of NCBC.

                  6.  Representations,  Warranties  and  Covenants  of PBI.  PBI
represents and warrants to NCBC as follows:

                  (a) Due Authorization. This Agreement has been duly authorized
by all necessary  corporate action on the part of PBI, has been duly executed by
a duly authorized  officer of PBI and constitutes a valid and binding obligation
of PBI. No shareholder  approval by PBI  shareholders  is required by applicable
law or otherwise before the exercise of the Option in whole or in part.

                  (b) Option Shares.  PBI has taken all necessary  corporate and
other  action to  authorize  and  reserve  and to permit it to issue and, at all
times from the date of this  Agreement to such time as the obligation to deliver
shares under this Agreement terminates,  will have reserved for issuance, at the
closing(s)  upon  exercise  of  the  Option,   the  Option  Shares  (subject  to
adjustment,  as provided in Section 8 below),  all of which, upon issuance under
this Agreement,  will be duly and validly issued,  fully paid and nonassessable,
and will be  delivered  free and clear of all claims,  liens,  encumbrances  and
security interests, including any preemptive right of any of the shareholders of
PBI.
<PAGE>
                  (c) No  Conflicts.  Neither the execution and delivery of this
Agreement  nor the  consummation  of the  transactions  contemplated  by it will
violate or result in any  violation  of or be in conflict  with or  constitute a
default  under  any  term of the  charter  or  bylaws  of PBI or any  agreement,
instrument,  judgment,  decree,  law,  rule or  order  applicable  to PBI or any
subsidiary of PBI or to which PBI or any such subsidiary is a party.

                  (d)  Notification  of Record Date.  At any time from and after
the date of this Agreement until the Option is no longer  exercisable,  PBI will
give NCBC at least 10 days prior written  notice before  setting the record date
for  determining  the holders of record of the PBI Common Stock entitled to vote
on any transaction described in Section 2 above.

                  7.  Representations,  Warranties  and Covenants of NCBC.  NCBC
represents and warrants to PBI as follows:

                  (a) Due Authorization. This Agreement has been duly authorized
by all necessary corporate action on the part of NCBC, has been duly executed by
a duly authorized officer of NCBC and constitutes a valid and binding obligation
of NCBC.

                  (b) No  Conflicts.  Neither the execution and delivery of this
Agreement  nor the  consummation  of the  transactions  contemplated  by it will
violate or result in any  violation  of or be in conflict  with or  constitute a
default under any term of the charter or bylaws of NCBC or
any agreement,  instrument,  judgment,  decree, law, rule or order applicable to
NCBC or any  subsidiary  of NCBC or to which  NCBC or any such  subsidiary  is a
party.

                  8. Adjustment Upon Changes in Capitalization.  In the event of
any  change in the PBI  Common  Stock by reason of stock  dividends,  split-ups,
mergers, reorganizations,  recapitalizations,  combinations, exchanges of shares
or the like,  the number and kind of shares or securities  subject to the Option
and the purchase price per share of Common Stock will be appropriately adjusted.
If, before the Option  terminates  or is  exercised,  PBI is acquired by another
party,  or  consolidates  with or merges  into  another  corporation,  NCBC will
thereafter receive, upon exercise of the Option, the securities or properties to
which a holder of the number of shares of Common Stock then deliverable upon the
exercise thereof would have been entitled upon such acquisition,  consolidation,
merger, or  reorganization,  and PBI will take all steps in connection with such
acquisition,  consolidation,  merger, or reorganization,  as may be necessary to
assure that the provisions of this Agreement will  thereafter be applicable,  as
nearly as  reasonably  may be  practicable,  in  relation to any  securities  or
property thereafter deliverable upon exercise of the Option.

                  9. Binding Effect; Assignment. This Agreement binds and inures
to the  benefit  of the  parties  and their  successors.  Except as set forth in
Section 5, this Agreement is not assignable by either party.

                  10. Regulatory Restrictions. Upon exercise of this Option, PBI
will use its best efforts to obtain or to cooperate  with NCBC in obtaining  all
necessary  regulatory  consents,  approvals,  waivers or other  action  (whether
regulatory,  corporate or other) to permit the  acquisition of any or all Option
Shares by NCBC.
<PAGE>
                  11.  No  Rights  as  Shareholder.  This  Option,  before it is
exercised,  will not entitle its holder to any rights as a shareholder of PBI at
law or in equity.  Specifically,  this Option, before it is exercised,  will not
entitle the holder to vote on any matter  presented to the  shareholders  of PBI
or,  except as  provided  in this  Agreement,  to any notice of any  meetings of
shareholders or any other proceedings of PBI.

                  12. Miscellaneous.

                  (a) Termination.  This Agreement and the Option will terminate
upon the earliest of (1) the mutual  agreement of the parties to this Agreement;
(2) the 90th day  following  the  termination  of the Merger  Agreement  for any
reason;  or (3) 12 months  after the date  hereof;  but if the  Option  has been
exercised before the termination of this Agreement, then the exercise will close
under  Section 4 of this  Agreement,  even though that closing date is after the
termination of this Agreement.

                  (b) Amendments.  This Agreement may not be modified,  amended,
altered or  supplemented,  except upon the  execution  and delivery of a written
agreement executed by the parties.

                  (c)  Severability  of Terms.  Any provision of this  Agreement
that is invalid,  illegal or  unenforceable is ineffective only to the extent of
the invalidity,  illegality or unenforceability without affecting in any way the
remaining  provisions  or  rendering  any  other  provisions  of this  Agreement
invalid,  illegal or  unenforceable.  Without  limiting  the  generality  of the
foregoing,  if the right of NCBC to  exercise  the  Option in full for the total
number of shares of PBI Common Stock or other  securities  or property  issuable
upon the exercise of the Option is limited by applicable law, or otherwise, NCBC
may, nevertheless, exercise the Option to the fullest extent permissible.

                  (d) Notices. All notices,  requests, claims, demands and other
communications  under this  Agreement  must be in writing and must be given (and
will be deemed to have been duly  received if so given) by  delivery,  by cable,
telecopies or telex, or by registered or certified mail, postage prepaid, return
receipt requested,  to the respective parties at the addresses below, or to such
other  address as either  party may furnish to the other in  writing.  Change of
address notices will be effective upon receipt.

                                     (Date)

National Commerce Bancorporation
One Commerce Square
Memphis, TN  38150
Attention:        William R. Reed
                  Vice Chairman

Dear Mr. Reed:

                  The  undersigned  is a shareholder of Piedmont  Bancorp,  Inc.
("PBI"),  a corporation  organized  and existing  under the laws of the State of
North   Carolina,   and  will  become  a   shareholder   of  National   Commerce
Bancorporation  ("NCBC") pursuant to the transactions described in the Agreement
and Plan of Reorganization, dated as of December 27, 1999, (the "Agreement"), by
and between NCBC and PBI. Under the terms of the  Agreement,  PBI will be merged
with and into NCBC (the  "Merger"),  and the  shares of the no par value  common
stock of PBI ("PBI  Common  Stock")  will be converted  into and  exchanged  for
shares of the $2.00 par value common stock of NCBC ("NCBC Common  Stock").  This
Affiliate  Agreement  represents an agreement  between the  undersigned and NCBC
regarding  rights and  obligations  of the  undersigned  in connection  with the
shares of NCBC to be received by the undersigned as a result of the Merger.

                  In  consideration  of the  Merger  and  the  mutual  covenants
contained herein, the undersigned and NCBC hereby agree as follows:

                  1. Affiliate  Status.  The undersigned  understands and agrees
that the undersigned is an "affiliate"  under Rule 145(c) as defined in Rule 405
of the Rules and Regulations of the Securities and Exchange  Commission  ("SEC")
under the Securities Act of 1933, as amended ("1933 Act"),  and the  undersigned
anticipates  that the undersigned will be such an "affiliate" at the time of the
Merger.

                  2. Initial Restriction on Disposition.  The undersigned agrees
that the  undersigned  will not sell,  transfer,  or  otherwise  dispose  of the
undersigned's  interests in or reduce the undersigned's risk relative to, any of
the  shares of NCBC  Common  Stock into  which the  undersigned's  shares of PBI
Common Stock are converted  upon  consummation  of the Merger until such time as
the requirements of SEC Accounting Series Release Nos. 130 and 135 ("ASR 130 and
135") have been met. The undersigned  understands that ASR 130 and 135 relate to
publication of financial results of post-Merger  combined operations of NCBC and
PBI. NCBC agrees that it will publish such results  within 45 days after the end
of  the  first  fiscal  quarter  of  NCBC  containing  the  required  period  of
post-Merger combined operations.

                  3. Covenants and Warranties of  Undersigned.  The  undersigned
represents, warrants, and agrees that:
<PAGE>
                  (a) During the 30 days  immediately  preceding  the  Effective
Time of the Merger,  the  undersigned  has not sold,  transferred,  or otherwise
disposed of the undersigned's  interests in, or reduced the  undersigned's  risk
relative  to, any of the shares of PBI Common  Stock  beneficially  owned by the
undersigned as of the date of the  Shareholder's  Meeting of PBI held to approve
the Merger.

                  (b) The NCBC Common  Stock  received by the  undersigned  as a
result of the Merger will be taken for the undersigned's own account and not for
others, directly or indirectly, in whole or part.

                  (c) NCBC has informed the undersigned that any distribution by
the undersigned of NCBC Common Stock has not been registered  under the 1933 Act
and that shares of NCBC Common Stock received pursuant to the Merger can only be
sold by the undersigned (1) following registration under the 1933 Act, or (2) in
conformity with the volume and other  requirements of Rule 145(d) promulgated by
the SEC as the same now exists or may hereafter be amended, or (3) to the extent
some other  exemption from  registration  under the 1933 Act might be available.
The  undersigned  understands  that  NCBC  is  under  no  obligation  to  file a
registration   statement   with  the  SEC  covering  the   disposition   of  the
undersigned's  shares of NCBC Common Stock or to take any other action necessary
to make compliance with an exemption from such registration available.

                  (d) The  undersigned  will,  and will  cause each of the other
parties  whose  shares are deemed to be  beneficially  owned by the  undersigned
pursuant to Section 8 hereof to have all shares of PBI Common Stock beneficially
owned  by the  undersigned  registered  in the name of the  undersigned  or such
parties, as applicable, prior to the Effective Date of the Merger and not in the
name of any banker, broker-dealer, nominee, or clearinghouse.

                  (e) The  undersigned  is aware that NCBC  intends to treat the
Merger as a tax-free  reorganization  under Section 368 of the Internal  Revenue
Code ("Code") for federal income tax purposes.  The undersigned  agrees to treat
the transaction in the same manner as NCBC for federal income tax purposes.  The
undersigned  acknowledged that Section  1.368-1(b) of the Income Tax Regulations
requires  "continuity  of  interest"  in order for the  Merger to be  treated as
tax-free under Section 368 of the Code. This requirement is satisfied if, taking
into  account  those PBI  shareholders  who receive  cash in lieu of  fractional
shares, there is not a plan, or intention on the part of the PBI shareholders to
sell or otherwise dispose of the NCBC Common Stock to be received in the Merger.
The  undersigned has no  prearrangement,  plan or intention to sell or otherwise
dispose of an amount of his NCBC Common Stock to be received in the Merger which
would cause the foregoing requirement not to be satisfied.

                  4. Restrictions on Transfer.  The undersigned  understands and
agrees that stop order  instructions  with  respect to the shares of NCBC Common
Stock received by the undersigned pursuant to the Merger will be given to NCBC's
Transfer Agent and that there will be placed on the certificates of such shares,
or shares issued in substitution thereof, a legend stating in substance:

                  "The  shares  represented  by  this  certificate  were  issued
                  pursuant to a business combination which is accounted for as a
                  "pooling of interests"  and may not be sold, nor may the owner
                  thereof  reduce his risks  relative  thereto in any way, until
                  such time as National  Commerce  Bancorporation  ("NCBC")  has

                  be sold,  transferred,  or  otherwise  disposed  of  except or
                  unless (1)  covered  by an  effective  registration  statement

                  accordance  with (i)Rule  145(d) (in the case of shares issued

undersigned  has carefully read the Agreement and this  Affiliate  Agreement and
discussed their requirements and impact upon his ability to sell,  transfer,  or
otherwise   dispose  of  the  shares  of  NCBC  Common  Stock  received  by  the
undersigned, to the extent he believes necessary, with his counsel or counsel or
PBI.

three years after the  Effective  Time of the Merger,  to file on a timely basis
all reports  required to be filed by it pursuant to Section 13 of the Securities

                  (a) Termination by Employer For Cause.  Employer may terminate
this Agreement for cause  pursuant to notice in writing to Employee,  specifying
such cause with reasonable particularity. Employee shall have ten (10) days from
receipt  thereof in which to cure the act or omission  complained of, unless the
act or omission of its very nature cannot be cured within such period,  in which
event if the Employee  shall have begun  diligently  working to cure such act or
omission during such period, then the Employee shall have a reasonable period of
time to effect such cure so long as the Employee continues to work diligently to

allowed, this Agreement shall thereupon terminate.

                  For purposes hereof, "cause" shall be limited to:

                         (i)  Any material act of self-dealing  between Employer

                              and approved by, the Employer;

                         (ii) Deliberate   falsification   by  Employee  of  any
                              records or reports;
<PAGE>
                         (iii)Fraud on the part of Employee against the Employer
                              or any subsidiary or affiliate;

                         (iv) Theft,   embezzlement   or   misappropriation   by
                              Employee of any funds of Employer,  or  conviction
                              of any felony; or

                         (v)  Personal   dishonesty,    incompetence,    willful
                              misconduct,  breach of  fiduciary  duty  involving
                              personal  profit,  intentional  failure to perform
                              stated duties, willful violation of any law, rule,
                              regulation  (other  than  traffic   violations  or
                              similar offenses) or final  cease-and-desist order
                              or  material  breach  of any  provisions  of  this
                              Employment Agreement.

                  In  the  event  of  Employee's   termination  for  cause,  all
compensation  and benefits due under this Agreement shall terminate  thirty (30)
days from the effective date of termination.

                  It is agreed,  however,  that  except for an occasion in which
the  Employer,  in the  exercise of its  reasonable  discretion,  believes  that
Employee's removal upon the aforesaid ten (10) days' notice is necessary for the
protection of the Employer,  the Employer shall give Employee  written notice of
the violation or reason that it desires to terminate him and at least sixty (60)
calendar days  (exclusive of Federal and State  holidays) to reasonably cure any
violation or to address any other  ground  stated by the Employer in its written
notice. The Employer's written notice shall describe the facts and circumstances
of the alleged breach or violation in reasonable detail.

                  Any notice from the Employer to Employee  concerning a "cause"
for  removal  shall be  deemed  a demand  for  cure of the  asserted  breach  or
violation.  The Employer  may  terminate  Employee for the reasons  specified in
Subparagraph  (a)(ii) through (a)(iv)  immediately upon sending Employee written
notice  describing  the facts and  circumstances  of the breach or  violation in
reasonable  detail,  but without  giving  Employee the  opportunity to cure such
violation(s)  or  breach(es).  If  Employee  is  acquitted,  not  convicted,  or
otherwise prevails in respect of the charges described in such Subparagraphs, he
shall be entitled to either (x) back pay and  reinstatement or (y) back pay plus
the Termination Payment (as herein defined), at his election, and the provisions
of Section V shall not apply unless the Employee chooses reinstatement under (x)
above.

                  Employee  shall  be  entitled  to  the  Termination   Payment,
together with interest thereon at the judgment rate of interest, if the Employer
terminates  Employee's  employment  for any reason other than those set forth in
this Paragraph VI(a).


                  Except  as  noted  above,  if  Employer   terminates  Employee
pursuant to this Section for the reasons specified in either Subparagraph (a)(i)
or (a)(v),  the  confidentiality  provisions  of Section V shall  terminate.  If
Employer  terminates Employee pursuant to this Section for the reasons specified
in  either  Subparagraph  (a)(ii);  (a)(iii);  or  (a)(iv)  the  confidentiality
provisions of Section V shall apply.

                  (b)  Termination by Employee For Cause.  The Employee shall be
authorized to terminate this Agreement for the following reasons:
<PAGE>
                        (i)  The   Employer   commits  a  material   breach  or
                              violation of this Agreement, including any attempt
                              to reassign the Employee to a different  office or
                              geographic  area,  which is not cured  before  the
                              expiration  of thirty  (30)  calendar  days  after
                              written notice from Employee  describing the facts
                              and  circumstances  of the breach or  violation in
                              reasonable  detail.  Such notice shall be deemed a
                              demand for cure of the breach or violation; and/or

                         (ii) The Employer persists, for a period of thirty (30)
                              calendar days after  written  notice from Employee
                              describing in  reasonable  detail the matter as to
                              which he is complaining, in any attempt to require
                              Employee to perform  (or omit to perform)  any act
                              or engage (or omit to engage) in any conduct  that
                              would constitute illegal conduct or omission. Such
                              notice  shall be deemed a demand for the  Employer
                              to cease any such attempt.

                  If Employee terminates his employment pursuant to this section
(b), the confidentiality provisions of Section V shall terminate.

                  If  Employee  terminates  his  employment  pursuant to Section
(b)(i) or  (b)(ii),  the  Employee  shall be  entitled  to  Termination  Payment
pursuant to Section (c)(iii) herein.

                  (c)  Termination  by  Either  Party  for  Non-Cause  or  Other
Reasons. Either party may terminate this Agreement upon ninety (90) days written
notice to the other party for any reason.  Termination  pursuant to this section
shall be referred to as a "Non-Cause  Termination."  Specifically,  a "Non-Cause
Termination"  shall be any termination of the Employee's  employment  other than
for cause, as defined in subparagraph VI(a) or IV(b) above.

                  (i)  Non-Cause  Termination  by  Employee.  In  the  event  of
termination  pursuant to this section (c) by the Employee,  all compensation and
benefits  due under this  Agreement  shall  terminate on the  effective  date of
termination. If Employee terminates his employment pursuant to this section (c),
the non-competition provisions of Section V shall apply.

                  (ii)  Non-Cause  Termination  by  Employer.  In the  event  of
termination  pursuant to this section (c) by Employer,  liquidated damages shall
be paid to Employee as  specified  in  subsection  (iii)  herein and referred to
herein as "Termination Payment."


                  (iii)  Termination  Payment.  In  the  event  of  a  Non-Cause
Termination by Employer  pursuant to Section  (c)(ii) above,  the Employer shall
pay the Employee a lump sum severance  amount, as liquidated  damages,  equal to
the  remaining  salary  (the"Termination  Payment")  due  and  payable  for  the
remainder of the original term of this  Agreement;  all of  Employee's  benefits
(such as retirement benefits,  stock options,  restricted stock grants and other
employee  benefits)  shall  immediately  be  vested  and all  health,  life  and
disability insurance coverage shall continue through the end of the term of this
Agreement  as if  there  had  been no  termination  and  with  health  insurance
continuing as set forth in Section IV(b)(1); and the confidentiality  provisions
of Section V shall immediately terminate.
<PAGE>
                  (d) Termination by Death.  This Agreement shall  automatically
terminate  upon the death of  Employee.  In such  event,  all  compensation  and
benefits due under this Agreement  shall terminate on Employee's  death,  except
for benefits  (such as life  insurance or stock  options)  specified in separate
written agreements or plans.

                  (e)   Termination   by  Retirement.   This   Agreement   shall
automatically   terminate  three  months  after  Employee's  sixty-fifth  (65th)
birthday.  In such event, all compensation and benefits due under this Agreement
shall terminate on Employee's  retirement.  No  non-competition  agreement shall
survive  termination  of the Employee's  employment for the reason  specified in
this provision.

                  (f) Termination  for  Disability.  Employer may terminate this
Agreement in the event that Employee  shall,  during the term of this Agreement,
become  permanently  disabled as defined in this  section.  Such option shall be
exercised  by  Employer  giving  notice in writing  to  Employee  of  Employer's
intention to terminate  this Agreement on the last day of the month in which the
notice is so  mailed,  with the same force and effect as if such last day of the
month were the date  originally set forth in this  Agreement as the  termination
date of this Agreement.  In such event,  all compensation and benefits due under
this Agreement shall terminate on the date of  termination.  No  confidentiality
agreement shall survive termination of the Employee's  employment for the reason
specified in this provision.

                  For the purposes of this  Agreement,  Employee shall be deemed
to have become  permanently  disabled,  if,  during any year of the term of this
Agreement, because of ill health, physical or mental incapacity he is completely
prevented from performing the minimum  requirements of his position for a period
of six (6) consecutive calendar months.

                  (g) Termination by Employer After Expiration of Initial Terms.
Upon the  expiration  of the initial  three (3) year term of this  Agreement set
forth in Section III,  Employer may  terminate  this  Agreement by delivering to
Employee written notice of Employer's  intent to terminate;  provided,  however,
that such written  notice must be  delivered  at least one hundred  eighty (180)
days prior to the end of the then current term of this Agreement,  including the
initial  three (3) year term of this  Agreement.  No  confidentiality  agreement
shall survive termination of the Employee's  employment for the reason specified
in this provision.

                  (h) Effect of Termination on Vested Benefits.  Notwithstanding
anything contained in this Agreement, Employee's termination of employment shall
not affect the Employer's  liability for the payment of vested benefits pursuant
to  individual  contracts or state or federal law  requiring the payment of such
benefits.

                                   SECTION VII

                          EFFECT OF PARTIAL INVALIDITY

                  The  invalidity of any portion of this  Agreement will not and
shall not be deemed to affect the validity of any other provision.  In the event

that the remaining  provisions shall be deemed to be in full force and effect as
if they had been  executed by both  parties  subsequent  to  elimination  of the
invalid provision.

performance  under this Agreement,  and all suits and special  proceedings under
this  Agreement,  be construed in accordance  with and under and pursuant to the
laws of the State of North Carolina and that, in any action,  special proceeding
or other  proceeding that may be brought arising out of, in connection  with, or
by any reason of this  Agreement,  the laws of the State of North Carolina shall
be applicable and shall govern to the exclusion of the law of the forum, without
regard to the  jurisdiction  in which any  action or special  proceeding  may be
instituted.  Disputes  under this  Agreement  shall be resolved in the state and
federal courts in North Carolina.

                                   SECTION XI
                                    NO WAIVER

                  The failure of either  Employer or Employee to insist upon the
performance of any of the terms and conditions of this Agreement,  or the waiver
of any breach of any of the terms and conditions of this Agreement, shall not be
construed  as  thereafter  waiving any such terms and  conditions,  but the same
shall continue and remain in full force and effect as if no such  forbearance or
waiver had occurred.

                                   SECTION XII
                                 ATTORNEYS' FEES

reasonable sum for the successful party's attorneys' fees.

                  b. Retention Bonus.  Employee shall be entitled to a retention
bonus  equal to two (2) weeks  pay if  Employee  remains  with the  Company  for

                  6. Termination of Agreement.  NBC may terminate this Agreement
and Employee's employment under this Agreement for any of the following causes:

                  a. Habitual absenteeism or lateness;

in effect on the effective date of this Agreement or as modified during the term
of this Agreement;

                  d. Employee's admission of, indictment for, or conviction in a
court of law of any crime or offense  that (i)  constitutes  a violation  of any
applicable federal, state or local laws or regulations involving a felony in the
jurisdiction  involved;  (ii) involves theft or embezzlement;  or (iii) involves
moral turpitude;

                  e. Employee's  inability or failure to perform  satisfactorily
the duties of its position,  or any other duties and/or position(s) which may be
assigned by NBC in accordance with this Agreement, such performance to be judged
in the  sole  discretion  of NBC,  if such  inability  or  failure  has not been
remedied  within a thirty (30) day period after  receipt of written  notice from
NBC of  such  inability  or  failure,  which  written  notice  must  state  with
specificity the obligations Employee has failed to perform; or
<PAGE>
                  f. Any  incident or pattern of conduct that might tend to hold
NBC up to ridicule in the community;

                  Notwithstanding any other term(s) of this Agreement,  NBC may,
at any time terminate  Employee's  employment for any cause listed above. In the
event NBC  terminates  Employee's  employment  for  cause,  as  defined  in this
Section,  NBC shall give Employee  written notice of such  termination and, upon
the  effective  date  of  termination  set  forth  in  such  notice,  Employee's
employment  shall be  terminated.  Except as provided in subsection  "e." above,
NBC's written notice of termination and the effective date of termination may be
simultaneous.  If Employee is terminated,  NBC shall pay Employee's  base salary
through  and  including  the  effective  date of  termination  but shall have no
obligation  to pay  Employee's  base salary for any period after such  effective
date of  termination  and shall have no obligation to pay Employee the retention
bonus described in Section 3(b) of this Agreement.

                  7. Confidentiality.  Employee agrees to keep in strict secrecy
and confidence any and all information of a confidential  nature as described in
the handbook that Employee may  assimilate or to which he may have access during
this  employment,  whether or not such  information  constitutes a trade secret.
Employee  agrees that both during and after the Term of Employment  with NBC, he
will not, without prior written consent of NBC,  disclose any such  confidential
information to any third person.

                  In the  event  of a  breach  of this  confidentiality  clause,
Employee will be responsible for any and all associated costs and legal expenses
incurred by NBC in connection with enforcing this provision.

                  8.  Non-Competition.  Employee hereby agrees that,  during the
Term of  Employment  and for a period of the lesser of six (6)  months  from the
date of termination of Employee's employment with NBC or the termination date of
this Agreement,  Employee shall not engage in the business of banking,  consumer
finance or other financial services and will not compete in any way with NBC. In
the  event  of a  breach  of  this  non-competition  clause,  Employee  will  be
responsible for any and all associated costs and legal expenses  incurred by NBC
in connection with enforcing this provision.

                  NBC and  Employee  agree  that  NBC may seek to  enforce  this
non-competition  clause in a judicial  court with proper  jurisdiction.  NBC and
Employee  agree  that  if a  judicial  determination  is  made  that  any of the
provisions  of  this  non-competition  clause  constitutes  an  unreasonable  or
otherwise  unenforceable  restriction  against Employee,  the provisions of this
non-competition  clause  shall be  rendered  void  only to the  extent  of those
provisions  found to be  unreasonable  or otherwise  unenforceable.  The parties
hereby agree that any judicial or arbitral  authority  construing this Agreement
shall be empowered to sever any prohibited  business activity or any time period
from  the   coverage   of  this   non-competition   clause   and  to  apply  the
non-competition   provisions  to  the  remaining  business  activities  and  the
remaining time period.

                  9. Miscellaneous.

                  a.  Governing  Law. It is agreed between NBC and Employee that
the law of the State of _____________ will govern the interpretation,  validity,
and effect of this  Agreement  without regard to the place of execution or place
of performance thereof.
<PAGE>
                  b. Severability.  If any clause or provision in this Agreement
shall be adjudged to be invalid in any manner it shall not affect the  validity,
legality and  enforceability of any other clause or provision which shall remain
in full force and effect.

                  c.  Waivers.  No  waiver  by  either  party of any  breach  of
nonperformance  of any provision or obligation of this Agreement shall be deemed
to be a waiver of any  preceding or  succeeding  breach of the same or any other
provision of this Agreement.

                  d.  Assignment.   Neither  party  may  assign  its  rights  or
obligations  under this Agreement without the prior written consent of the other
party, provided, however, that at the sole option of NBC or NCBC, this Agreement
may be  assigned  without the prior  written  consent of Employee to any banking
affiliate of NBC or to any banking affiliate  acquiring all of the assets of NBC
or to any banking  affiliate  into which NBC may be merged or  consolidated.  An
"affiliate" of NBC shall be defined as any entity that  indirectly,  through one
or more  intermediary's  controls,  is controlled by, or is under common control
with NBC. If the NCBC acquires or forms subsidiary companies,  becomes connected
with  other  affiliate  companies  by  acquisition,  merger,  consolidation,  or
otherwise,  Employee  agrees to be employed by any of the same and in such event
all of the terms and conditions set forth herein shall bind the parties.

                  e. Arbitration.  Except as otherwise provided, any controversy
or claim  arising  out of or  relating  to this  Agreement  shall be  settled in
accordance with the rules of the American Arbitration  Association.  The parties
agree to be bound by the majority  decision of the arbitrators.  The Arbitration
proceeding  shall  take  place in  ___________________________,  unless  another
location  is  mutually  agreed  upon  in  writing  by  the  parties.  Three  (3)
arbitrators shall be selected for the arbitration panel. Each party shall select
one (1) arbitrator.  The arbitrators  named by each party shall select the third
arbitrator.  The cost and expenses of the arbitration proceeding itself shall be
shared equally by the parties;  however, each party shall be responsible for its
own legal expenses and costs in connection with arbitrating such a dispute.  The
award of the  arbitrator  shall be final and a judgment on the award rendered by
the  arbitrator  may be entered in any court  having  jurisdiction  there.  This
provision shall survive the termination of this Agreement.

                  In the event of  noncompliance  or violation,  as the case may
be, by Employee of paragraphs 7 (Confidentiality)  and/or 8 (Non-Competition) of
this     Agreement,      NBC     may     alternatively      apply     to     the
_________________________________  all legal and/or equitable  remedies that may
be available,  since NBC would have no adequate remedy at law for such violation
or noncompliance.

                  f. No Oral Modification.  No modification of this Agreement by
either party will be binding on NBC or Employee unless it is in writing,  signed
by both  parties,  and  approved  by the current  Chairman of National  Commerce
Bancorporation.

                  g. Binding  Effect.  This Agreement shall inure to the benefit
of and bind the  parties  hereto and their  respective  heirs,  successors,  and
assigns, subject to subsection "d." herein above.


                  THIS  AGREEMENT  CONTAINS THE ENTIRE  AGREEMENT OF THE PARTIES
HERETO AND THEREFORE  SUPERSEDES ANY AND ALL OTHER ORAL OR WRITTEN AGREEMENTS OR
UNDERSTANDINGS.

                  Except as required by law, Employee agrees that he will not at
any time  communicate or divulge to, or use for his benefit,  or for the benefit
of  any  other  person,  firm,  association,  or  corporation,  any  information
concerning  Employer's  business  activities,   including,  without  limitation,
financial  projections  and models,  costs and sales data,  marketing  plans and
programs,  customer  lists,  loan  and  deposit  information,   and  methods  of
operations,  or other confidential matters possessed,  owned or used by Employer
that have been or may be  communicated  to, acquired by, or learned of by him in
the  course of or as a result of his  employment  with  Employer.  All  records,
files,  memoranda,  reports,  loan lists,  customer and  depositor  information,

term of his employment shall not be deemed confidential.

                  Employee  agrees that Employee will not, during the Restricted
Period  directly or by  assisting  others,  conduct  Company  Activities  in the
Restricted  Area, or otherwise  engage in, have an equity or profit interest in,
or render services in the Restricted  Area, to any business that conducts any of
the Company  Activities in the  Restricted  Area. The term  "Restricted  Period"

the over-the-counter  market.  Employee  acknowledges  Employer conducts Company
Activities with customers  throughout the United States,  and that to adequately
protect  the  interests  of  Employer it is  essential  that any  noncompetition
covenant  with respect  thereto cover all Company  Activities in the  Restricted
Area.  The  term  "Company  Activities"shall  mean  commercial  banking,  retail
banking, and mortgage banking.

                  The  parties  further  agree  that if a judicial  or  arbitral
determination  is made that any of the  provisions  of this  paragraph or of the
preceding  paragraph  constitutes  an  unreasonable  or otherwise  unenforceable
restriction against Employee, the provisions of this paragraph or such preceding
paragraph  shall be  rendered  void only to the  extent  that such  judicial  or
arbitral  determination  finds such  provisions to be  unreasonable or otherwise
unenforceable with respect to Employee. In this regard, the parties hereby agree
that any  judicial or arbitral  authority  construing  this  Agreement  shall be
empowered to sever any portion of the Restricted  Area, any prohibited  business
<PAGE>
activity  or any  time  period  from the  coverage  of this  paragraph  and such
preceding  paragraph  and to apply  the  provisions  of this  paragraph  or such
preceding  paragraph  to the  remaining  portion  of the  Restricted  Area,  the
remaining  business  activities  and the remaining time period not so severed by
such judicial or arbitral authority. Moreover, notwithstanding the fact that any
provision of this  paragraph or the preceding  paragraph is determined not to be
specifically  enforceable,  Employer shall  nevertheless  be entitled to recover
monetary damages as a result of the breach of such provision by Employee.

                                   SECTION VI
                                   TERMINATION

                  (a) Termination by Employer For Cause.  Employer may terminate
this Agreement for cause  pursuant to notice in writing to Employee,  specifying
such cause with reasonable particularity. Employee shall have ten (10) days from
receipt  thereof in which to cure the act or omission  complained of, unless the
act or omission of its very nature cannot be cured within such period,  in which
event if the Employee  shall have begun  diligently  working to cure such act or
omission during such period, then the Employee shall have a reasonable period of
time to effect such cure so long as the Employee continues to work diligently to
accomplish  such cure.  If no cure has been or can be  effected  within the time
allowed, this Agreement shall thereupon terminate.

                  For purposes hereof, "cause" shall be limited to:

                  (i)    Any material act of self-dealing  between  Employer and
                         Employee  which  is  not  disclosed  in  full  to,  and
                         approved by, the Employer;

                  (ii)   Deliberate  falsification by Employee of any records or
                         reports;

                  (iii)  Fraud on the part of Employee  against the  Employer or
                         any subsidiary or affiliate;

                  (iv)   Theft,  embezzlement or misappropriation by Employee of
                         any funds of Employer, or conviction of any felony; or

                  (v)    Personal dishonesty,  incompetence, willful misconduct,
                         breach of fiduciary  duty  involving  personal  profit,
                         intentional  failure to perform stated duties,  willful
                         violation  of any law,  rule,  regulation  (other  than
                         traffic   violations  or  similar  offenses)  or  final
                         cease-and-desist   order  or  material  breach  of  any
                         provisions of this Employment Agreement.

                  In  the  event  of  Employee's   termination  for  cause,  all
compensation  and benefits due under this Agreement shall terminate  thirty (30)
days from the effective date of termination.

                  It is agreed,  however,  that  except for an occasion in which
the  Employer,  in the  exercise of its  reasonable  discretion,  believes  that
Employee's removal upon the aforesaid ten (10) days' notice is necessary for the
protection of the Employer,  the Employer shall give Employee  written notice of
the violation or reason that it desires to terminate him and at least sixty (60)
calendar days  (exclusive of Federal and State  holidays) to reasonably cure any
violation or to address any other  ground  stated by the Employer in its written
notice. The Employer's written notice shall describe the facts and circumstances
of the alleged breach or violation in reasonable detail.
<PAGE>
                  Any notice from the Employer to Employee  concerning a "cause"
for  removal  shall be  deemed  a demand  for  cure of the  asserted  breach  or
violation.  The Employer  may  terminate  Employee for the reasons  specified in
Subparagraph  (a)(ii) through (a)(iv)  immediately upon sending Employee written
notice  describing  the facts and  circumstances  of the breach or  violation in
reasonable  detail,  but without  giving  Employee the  opportunity to cure such
violation(s)  or  breach(es).  If  Employee  is  acquitted,  not  convicted,  or
otherwise prevails in respect of the charges described in such Subparagraphs, he
shall be entitled to either (x) back pay and  reinstatement or (y) back pay plus
the Termination Payment (as herein defined), at his election, and the provisions
of Section V shall not apply unless the Employee chooses reinstatement under (x)
above.

                  Employee  shall  be  entitled  to  the  Termination   Payment,
together with interest thereon at the judgment rate of interest, if the Employer
terminates  Employee's  employment  for any reason other than those set forth in
this Paragraph VI(a).

                  Except  as  noted  above,  if  Employer   terminates  Employee
pursuant to this Section for the reasons specified in either Subparagraph (a)(i)
or (a)(v), the provisions of Section V shall terminate.  If Employer  terminates
Employee   pursuant  to  this  Section  for  the  reasons  specified  in  either
Subparagraph  (a)(ii);  (a)(iii);  or (a)(iv) the  provisions of Section V shall
apply.

                  (b)  Termination by Employee For Cause.  The Employee shall be
authorized to terminate this Agreement for the following reasons:


                  (i)    The Employer  commits a material breach or violation of
                         this  Agreement,  including any attempt to reassign the
                         Employee  to a  different  office or  geographic  area,
                         which is not cured before the expiration of thirty (30)
                         calendar  days  after  written   notice  from  Employee
                         describing the facts and circumstances of the breach or
                         violation in  reasonable  detail.  Such notice shall be
                         deemed a demand  for cure of the  breach or  violation;
                         and/or

                  (ii)   The  Employer  persists,  for a period of  thirty  (30)
                         calendar  days  after  written   notice  from  Employee
                         describing in reasonable  detail the matter as to which
                         he is complaining,  in any attempt to require  Employee
                         to perform (or omit to  perform)  any act or engage (or
                         omit to engage) in any  conduct  that would  constitute
                         illegal  conduct  or  omission.  Such  notice  shall be
                         deemed  a demand  for the  Employer  to cease  any such
                         attempt.

                  If Employee terminates his employment pursuant to this section
(b), the non-competition provisions of Section V shall terminate.

                  If  Employee  terminates  his  employment  pursuant to Section
(b)(i) or  (b)(ii),  the  Employee  shall be  entitled  to  Termination  Payment
pursuant to Section (c)(iii) herein.

Reasons. Either party may terminate this Agreement upon ninety (90) days written
notice to the other party for any reason.  Termination  pursuant to this section
shall be referred to as a "Non-Cause  Termination."  Specifically,  a "Non-Cause
Termination"  shall be any termination of the Employee's  employment  other than
for cause, as defined in subparagraph VI(a) or IV(b) above.

                  (i)    Non-Cause  Termination  by  Employee.  In the  event of
                         termination   pursuant  to  this  section  (c)  by  the
                         Employee,  all compensation and benefits due under this
                         Agreement  shall  terminate  on the  effective  date of
                         termination.  If  Employee  terminates  his  employment
                         pursuant  to  this  section  (c),  the  non-competition
                         provisions of Section V shall apply.

                  (ii)   Non-Cause  Termination  by  Employer.  In the  event of
                         termination  pursuant to this  section (c) by Employer,
                         liquidated   damages  shall  be  paid  to  Employee  as
                         specified  in  subsection  (iii) herein and referred to
                         herein as "Termination Payment."

                  (iii)  Termination  Payment.  In  the  event  of  a  Non-Cause
                         Termination  by Employer  pursuant  to Section  (c)(ii)
                         above,  the Employer  shall pay the Employee a lump sum
                         severance amount, as liquidated  damages,  equal to the
                         remaining  salary  (the"Termination  Payment")  due and
                         payable for the  remainder of the original term of this
                         Agreement;   all  of  Employee's   benefits   (such  as
                         retirement  benefits,  stock options,  restricted stock
                         grants and other employee  benefits) shall  immediately
                         be vested and all health, life and disability insurance
                         coverage shall continue  through the end of the term of
                         this Agreement as if there had been no termination  and
                         with  health  insurance  continuing  as  set  forth  in
                         Section IV(b)(1); and the non-competition provisions of
                         Section V shall immediately terminate.

                  (d) Termination by Death.  This Agreement shall  automatically
terminate  upon the death of  Employee.  In such  event,  all  compensation  and
benefits due under this Agreement  shall terminate on Employee's  death,  except
for benefits (such as life insurance or stock options) specified in separate
written agreements or plans.

                  (e)   Termination   by  Retirement.   This   Agreement   shall
automatically   terminate  three  months  after  Employee's  sixty-fifth  (65th)
birthday.  In such event, all compensation and benefits due under this Agreement
shall terminate on Employee's  retirement.  No  non-competition  agreement shall
survive  termination  of the Employee's  employment for the reason  specified in
this provision.

                  (f) Termination  for  Disability.  Employer may terminate this
Agreement in the event that Employee  shall,  during the term of this Agreement,
become  permanently  disabled as defined in this  section.  Such option shall be
exercised  by  Employer  giving  notice in writing  to  Employee  of  Employer's
intention to terminate  this Agreement on the last day of the month in which the
<PAGE>
notice is so  mailed,  with the same force and effect as if such last day of the
month were the date  originally set forth in this  Agreement as the  termination
date of this Agreement.  In such event,  all compensation and benefits due under
this Agreement shall terminate on the date of  termination.  No  non-competition
agreement shall survive termination of the Employee's  employment for the reason
specified in this provision.

                  For the purposes of this  Agreement,  Employee shall be deemed
to have become  permanently  disabled,  if,  during any year of the term of this
Agreement, because of ill health, physical or mental incapacity he is completely
prevented from performing the minimum  requirements of his position for a period
of six (6) consecutive calendar months.

                  (g) Termination by Employer After Expiration of Initial Terms.
Upon the  expiration  of the initial  three (3) year term of this  Agreement set
forth in Section III,  Employer may  terminate  this  Agreement by delivering to
Employee written notice of Employer's  intent to terminate;  provided,  however,
that such written  notice must be  delivered  at least one hundred  eighty (180)
days prior to the end of the then current term of this Agreement,  including the
initial  three (3) year term of this  Agreement.  No  non-competition  agreement
shall survive termination of the Employee's  employment for the reason specified
in this provision.

                  (h) Effect of Termination on Vested Benefits.  Notwithstanding
anything contained in this Agreement, Employee's termination of employment shall
not affect the Employer's  liability for the payment of vested benefits pursuant
to individual contracts or state or federal law requiring the
payment of such benefits.

                                   SECTION VII
                         AGREEMENTS OUTSIDE OF CONTRACT

                  This Agreement contains the complete agreement  concerning the
employment  arrangement  between the Parties and shall, as of the effective date
hereof,  supersede  all  other  agreements  between  the  Parties.  The  Parties
stipulate that neither of them has made any  representation  with respect to the
subject matter of this Agreement or any representations  including the execution
and delivery of this Agreement except such  representations  as are specifically
set forth in this Agreement and each of the parties  acknowledges  that he or it
has relied on its own  judgment in  entering  into this  Agreement.  The Parties
further acknowledge that any payments or representations that may have been made
by either of them to the other prior to the date of executing this Agreement are
of no effect and that neither of them has relied thereon in connection  with his
or its dealings with the other.  However, any stock option agreement between the
Parties is not merged  into or affected by this  Agreement  except as  expressly
stated herein.

                                  SECTION VIII
                            MODIFICATION OF AGREEMENT

                  Any  modification  of this Agreement or additional  obligation

representative of each of them.

                                   SECTION IX
                          EFFECT OF PARTIAL INVALIDITY

                  The  invalidity of any portion of this  Agreement will not and
shall not be deemed to affect the validity of any other provision.  In the event
that any  provision of this  Agreement is held to be invalid,  the Parties agree
that the remaining  provisions shall be deemed to be in full force and effect as
if they had been  executed by both  parties  subsequent  to  elimination  of the
invalid provision.

                                    SECTION X
                             CHOICE OF LAW AND FORUM

                  It is the intention of the Parties that this Agreement and the
performance  under this Agreement,  and all suits and special  proceedings under
this  Agreement,  be construed in accordance  with and under and pursuant to the
laws of the State of North Carolina and that, in any action,  special proceeding
or other  proceeding that may be brought arising out of, in connection  with, or
by any reason of this  Agreement,  the laws of the State of North Carolina shall
be applicable and shall govern to the exclusion of the law of the forum, without
regard to the  jurisdiction  in which any  action or special  proceeding  may be
instituted.  Disputes  under this  Agreement  shall be resolved in the state and
federal courts in North Carolina.



                                   SECTION XI
                                    NO WAIVER

                  The failure of either  Employer or Employee to insist upon the
performance of any of the terms and conditions of this Agreement,  or the waiver
of any breach of any of the terms and conditions of this Agreement, shall not be
construed  as  thereafter  waiving any such terms and  conditions,  but the same
shall continue and remain in full force and effect as if no such  forbearance or
waiver had occurred.

                                   SECTION XII
                                 ATTORNEYS' FEES

                  In the  event  that any  action is filed in  relation  to this
Agreement,  the  unsuccessful  party in the section shall pay to the  successful
party,  in addition to all the sums that either party may be called on to pay, a
reasonable sum for the successful party's attorneys' fees.


                                  SECTION XIII
                               GENERAL PROVISIONS

                  13.2 In the event of a conflict  between  this  Agreement  and
Section 10 of the Stock Option Grant  received by the Employee on the  Effective
Date, this Agreement shall govern; except that the terms of this Agreement shall
govern the vesting of present or future stock option  agreements in the event of
a Non-Cause Termination.

                  13.3 This Agreement shall be null and void unless NCBC and PBI
merge pursuant to the terms of that certain Agreement and Plan of Reorganization
dated December 27, 1999.

                  IN  WITNESS  WHEREOF,   the  Parties  now  duly  execute  this

                                   EXHIBIT 10

                             STOCK OPTION AGREEMENT

This STOCK OPTION  AGREEMENT  ("Agreement"),  dated as of December 27, 1999,  is
between NATIONAL COMMERCE  BANCORPORATION  ("NCBC") and PIEDMONT  BANCORP,  INC.
("PBI").

                                    RECITALS

                  PBI  and  NCBC  have   executed  an  Agreement   and  Plan  of
Reorganization  ("Merger  Agreement"),  of even date with this Agreement,  under
which  PBI will be  merged  with and into NCBC  upon  completion  of the  merger
("Merger") contemplated in the Merger Agreement.

                  By  negotiating  and  executing  the Merger  Agreement  and by
taking actions necessary or appropriate to effect the transactions  contemplated
by the Merger Agreement, NCBC has incurred and will incur substantial direct and
indirect  costs  (including,  without  limitation,  the costs of management  and
employee time) and will forgo the pursuit of certain alternative investments and
transactions.

                                    AGREEMENT

                  THEREFORE,  in consideration of the promises set forth in this
Agreement and in the Merger Agreement, the parties agree as follows:

                  1. Grant of Option.  Subject to the terms and  conditions  set
forth in this Agreement,  PBI irrevocably grants an option ("Option") to NCBC to
purchase that number of authorized but unissued shares of PBI's common stock, no
par value per share ("PBI Common Stock"),  such that immediately  following such
purchase  NCBC  would own 19.5% of the then  issued and  outstanding  shares (as
adjusted as set forth  herein) of PBI Common  Stock after  giving  effect to the
exercise  of the Option at a per share price in cash (or  immediately  available
funds) equal to $7.65 ("Option Price").

                  2.  Exercise  of  Option.  Subject to the  provisions  of this
Section 2 and of Section 12(a) of this  Agreement,  this Option may be exercised
by NCBC as set forth in Section 5 of this Agreement, in whole or in part, at any
time, in any of the following circumstances:

                  (a) PBI enters into an  agreement  or PBI's Board of Directors
recommends to PBI shareholders (or withdraws its  recommendation FOR approval of
the  Merger  after  receipt of a proposal  for PBI to enter  into) an  agreement
(other than the Merger  Agreement)  under --- which any entity,  person or group
(collectively  "Person"),   within  the  meaning  of  Section  13(d)(3)  of  the
Securities  Exchange Act of 1934, as amended ("Exchange Act"),  would: (1) merge
or consolidate  with,  acquire 25% or more of the assets or  liabilities  of, or
enter into any  similar  transaction  with PBI,  or (2)  purchase  or  otherwise
acquire (including by merger, reorganization,  consolidation,  share exchange or
any similar  transaction)  securities  representing  25% or more of PBI's voting
shares;

                  (b) any Person  (other  than NCBC or any of its  subsidiaries)
acquires the beneficial  ownership or the right to acquire beneficial  ownership
of securities  which,  when aggregated with other such securities  owned by such
Person, represents 25% or more of the voting shares of PBI (the term "beneficial
<PAGE>
ownership"  for purposes of this  Agreement has the meaning set forth in Section
13(d) of the Exchange Act, and the  regulations  promulgated  under the Exchange
Act) (not  including  acquisitions  pursuant to which the  acquiror or acquiring
group has successfully rebutted the presumption of control pursuant to 12 C.F.R.
ss.574(e) and has voted or given to management  of PBI an  irrevocable  proxy to
vote the  securities  so acquired  for the approval of the Merger at any and all
meetings of  shareholders of PBI called for that purpose or at which such matter
is considered (a "Rebuttal Acquisition");

                  (c)  failure  of the  shareholders  to  approve,  prior to the
termination of the Merger Agreement, the Merger by the required affirmative vote
at a meeting of the  shareholders,  because a third Person (other than NCBC or a
subsidiary of NCBC) announces  publicly or  communicates,  in writing,  to PBI a
proposal  to (a)  acquire PBI (by  merger,  reorganization,  consolidation,  the
purchase  of 25% or more of its  assets or  liabilities,  or any  other  similar
transaction),  or (b) purchase or otherwise acquire securities  representing 25%
or more of the voting shares of PBI.

                  (d) It is  understood  and agreed  that the Option will become
exercisable  immediately  upon  the  occurrence  of any  of the  above-described
circumstances  even though the circumstance  occurred as a result, in part or in
whole, of the board of PBI complying with its fiduciary duties.

                  (e)  Notwithstanding  any other provision of this Agreement to
the contrary, in no event shall:

                                    (i) NCBC's Total  Profit (as defined  below)
                  exceed  $1,035,000  and,  if it  otherwise  would  exceed such
                  amount, NCBC at its sole election, shall either (A) reduce any
                  remaining  shares of PBI Common  Stock  subject to the Option,
                  (B)  deliver  to PBI for  cancellation  without  consideration
                  shares  of PBI  Common  Stock  previously  purchased  by  NCBC
                  pursuant to the  exercise of the Option,  (C) pay cash to PBI,
                  or (D) any combination of the foregoing, so that NCBC's actual
                  realized Total Profit shall not exceed $1,035,000 after taking
                  into account the foregoing actions; or

                                    (ii) the Option be exercised for a number of
                  shares  of PBI  Common  Stock  as  would,  as of the  date  of
                  exercise,  result in NCBC's Total Notional  Profit (as defined
                  below) exceeding  $1,035,000;  provided,  that nothing in this
                  clause  (ii)  shall   restrict  any  exercise  of  the  Option
                  permitted hereby on any subsequent date.

                  As used in this Agreement,  the term "Total Profit" shall mean
the aggregate sum (prior to the payment of taxes) of the following:  (i) any net
cash amounts received by NCBC pursuant to the sale of shares of PBI Common Stock
received  pursuant to the exercise of the Option ( or any other  securities into
which such shares shall be converted or  exchanged) to any  unaffiliated  person
less NCBC's  purchase  price of such  shares;  (ii) any amount  received by NCBC
pursuant to PBI's repurchase of shares of PBI Common Stock received  pursuant to
the exercise of the Option less NCBC's purchase price of such shares,  and (iii)
any amount  received by NCBC pursuant to PBI's  repurchase of the Option (or any
portion thereof).
<PAGE>
                  As used in this Agreement,  the term "Total  Notional  Profit"
with  respect to any  number of shares of PBI Common  Stock as to which NCBC may
propose to exercise the Option shall be the Total  Profit  determined  as of the
date of such proposed exercise,  assuming that the Option were exercised on such
date for such number of shares and assuming that such shares,  together with all
other  such  shares  held by NCBC or its  affiliates  as of such  date that were
issued pursuant to the exercise of the Option, were sold for cash at the closing
sale  price  per share of PBI  Common  Stock as  quoted  on the  American  Stock
Exchange  ("AMEX")  or, if PBI  Common  Stock in not then  quoted  on AMEX,  the
highest  bid  price  per share as  quoted  on the  principal  trading  market or
securities  exchange on which such shares are traded as reported by a recognized
source chosen by NCBC as of the close of business on the  preceding  trading day
(less customary brokerage commissions).

                  3.  Notice,  Time and Place of  Exercise.  When NCBC wishes to
exercise the Option,  NCBC will give written notice of its intention to exercise
the Option and the place and date for the  closing of the  exercise  (which date
may not be later than ten business days from the date such notice is mailed). If
any law,  regulation  or other  restriction  will not permit such exercise to be
consummated  during  this  ten-day  period,  the  date for the  closing  of such
exercise will be within five days following the cessation of the  restriction on
consummation.

                  4. Payment and Delivery of Certificate(s).  At the closing for
the  exercise of the Option or any portion  thereof,  (a) NCBC and PBI will each
deliver to the other certificates as to the accuracy, as of the closing date, of
their respective  representations and warranties under this Agreement,  (b) NCBC
will pay the aggregate  purchase  price for the shares of PBI Common Stock to be
purchased  by delivery of a certified  or bank  cashier's  check in  immediately
available  funds payable to the order of PBI, and (c) PBI will deliver to NCBC a
certificate or certificates representing the shares so purchased.

                  5.  Transferability of the Option.  Neither the Option nor any
portion of the Option will be transferable  except to a wholly-owned  subsidiary
of NCBC.

                  6.  Representations,  Warranties  and  Covenants  of PBI.  PBI
represents and warrants to NCBC as follows:

                  (a) Due Authorization. This Agreement has been duly authorized
by all necessary  corporate action on the part of PBI, has been duly executed by
a duly authorized  officer of PBI and constitutes a valid and binding obligation
of PBI. No shareholder  approval by PBI  shareholders  is required by applicable
law or otherwise before the exercise of the Option in whole or in part.

                  (b) Option Shares.  PBI has taken all necessary  corporate and
other  action to  authorize  and  reserve  and to permit it to issue and, at all
times from the date of this  Agreement to such time as the obligation to deliver
shares under this Agreement terminates,  will have reserved for issuance, at the
closing(s)  upon  exercise  of  the  Option,   the  Option  Shares  (subject  to
adjustment,  as provided in Section 8 below),  all of which, upon issuance under
this Agreement,  will be duly and validly issued,  fully paid and nonassessable,
and will be  delivered  free and clear of all claims,  liens,  encumbrances  and
security interests, including any preemptive right of any of the shareholders of
PBI.
<PAGE>
                  (c) No  Conflicts.  Neither the execution and delivery of this
Agreement  nor the  consummation  of the  transactions  contemplated  by it will
violate or result in any  violation  of or be in conflict  with or  constitute a
default  under  any  term of the  charter  or  bylaws  of PBI or any  agreement,
instrument,  judgment,  decree,  law,  rule or  order  applicable  to PBI or any
subsidiary of PBI or to which PBI or any such subsidiary is a party.

                  (d)  Notification  of Record Date.  At any time from and after
the date of this Agreement until the Option is no longer  exercisable,  PBI will
give NCBC at least 10 days prior written  notice before  setting the record date
for  determining  the holders of record of the PBI Common Stock entitled to vote
on any transaction described in Section 2 above.

                  7.  Representations,  Warranties  and Covenants of NCBC.  NCBC
represents and warrants to PBI as follows:

                  (a) Due Authorization. This Agreement has been duly authorized
by all necessary corporate action on the part of NCBC, has been duly executed by
a duly authorized officer of NCBC and constitutes a valid and binding obligation
of NCBC.

                  (b) No  Conflicts.  Neither the execution and delivery of this
Agreement  nor the  consummation  of the  transactions  contemplated  by it will
violate or result in any  violation  of or be in conflict  with or  constitute a
default  under  any term of the  charter  or  bylaws  of NCBC or any  agreement,
instrument,  judgment,  decree,  law,  rule or order  applicable  to NCBC or any
subsidiary of NCBC or to which NCBC or any such subsidiary is a party.

                  8. Adjustment Upon Changes in Capitalization.  In the event of
any  change in the PBI  Common  Stock by reason of stock  dividends,  split-ups,
mergers, reorganizations,  recapitalizations,  combinations, exchanges of shares
or the like,  the number and kind of shares or securities  subject to the Option
and the purchase price per share of Common Stock will be appropriately adjusted.
If, before the Option  terminates  or is  exercised,  PBI is acquired by another
party,  or  consolidates  with or merges  into  another  corporation,  NCBC will
thereafter receive, upon exercise of the Option, the securities or properties to
which a holder of the number of shares of Common Stock then deliverable upon the
exercise thereof would have been entitled upon such acquisition,  consolidation,
merger, or  reorganization,  and PBI will take all steps in connection with such
acquisition,  consolidation,  merger, or reorganization,  as may be necessary to
assure that the provisions of this Agreement will  thereafter be applicable,  as
nearly as  reasonably  may be  practicable,  in  relation to any  securities  or
property thereafter deliverable upon exercise of the Option.

                  9. Binding Effect; Assignment. This Agreement binds and inures
to the  benefit  of the  parties  and their  successors.  Except as set forth in
Section 5, this Agreement is not assignable by either party.

                  10. Regulatory Restrictions. Upon exercise of this Option, PBI
will use its best efforts to obtain or to cooperate  with NCBC in obtaining  all
necessary  regulatory  consents,  approvals,  waivers or other  action  (whether
regulatory,  corporate or other) to permit the  acquisition of any or all Option
Shares by NCBC.
<PAGE>
                  11.  No  Rights  as  Shareholder.  This  Option,  before it is
exercised,  will not entitle its holder to any rights as a shareholder of PBI at
law or in equity.  Specifically,  this Option, before it is exercised,  will not
entitle the holder to vote on any matter  presented to the  shareholders  of PBI
or,  except as  provided  in this  Agreement,  to any notice of any  meetings of
shareholders or any other proceedings of PBI.

                  12. Miscellaneous.

                  (a) Termination.  This Agreement and the Option will terminate
upon the earliest of (1) the mutual  agreement of the parties to this Agreement;
(2) the 90th day  following  the  termination  of the Merger  Agreement  for any
reason;  or (3) 12 months  after the date  hereof;  but if the  Option  has been
exercised before the termination of this Agreement, then the exercise will close
under  Section 4 of this  Agreement,  even though that closing date is after the
termination of this Agreement.

                  (b) Amendments.  This Agreement may not be modified,  amended,
altered or  supplemented,  except upon the  execution  and delivery of a written
agreement executed by the parties.

                  (c)  Severability  of Terms.  Any provision of this  Agreement
that is invalid,  illegal or  unenforceable is ineffective only to the extent of
the invalidity,  illegality or unenforceability without affecting in any way the
remaining  provisions  or  rendering  any  other  provisions  of this  Agreement
invalid,  illegal or  unenforceable.  Without  limiting  the  generality  of the
foregoing,  if the right of NCBC to  exercise  the  Option in full for the total
number of shares of PBI Common Stock or other  securities  or property  issuable
upon the exercise of the Option is limited by applicable law, or otherwise, NCBC
may, nevertheless, exercise the Option to the fullest extent permissible.

                  (d) Notices. All notices,  requests, claims, demands and other
communications  under this  Agreement  must be in writing and must be given (and

NCBC to Acquire Hillsborough Savings Bank; Acquisition to Enhance North Carolina
Market Coverage

December 28, 1999 08:09 AM Eastern Time MEMPHIS,  Tenn., Dec. 28 /PRNewswire/ --
National Commerce  Bancorporation  NCBC and Piedmont Bancorp.,  Inc. (Amex: PDB)
announced today an agreement whereby NCBC will acquire Piedmont Bancorp.,  Inc.,
the holding company of Hillsborough Savings Bank, Inc., SSB, through an exchange
of ---- stock. Based upon the recent trading prices for NCBC's common stock, the
aggregate purchase price paid by NCBC would be $34.5 million and would result in
Piedmont  Bancorp.  shareholders  receiving  shares  valued at  $12.52  for each
Piedmont Bancorp.  share held,  subject to certain  limitations set forth in the
merger agreement.

The  transaction,  expected  to close late in the first  quarter or early in the
second quarter of 2000, is subject to shareholder and regulatory approval.  Once
the transaction is completed,  NCBC will operate the  Hillsborough  Savings Bank
locations as branches of NBC Bank, FSB, its North Carolina banking subsidiary.

Hillsborough  Savings  Bank is a $147  million-asset  bank  with  three  banking
offices in  Hillsborough,  Chapel Hill and Durham,  N.C. NBC Bank, FSB is a $344
million-asset  bank with 23  branches  and 24 ATMs  concentrated  in the state's
"Triangle"  region,  as defined by the geographic  positions of cities  Raleigh,
Durham, and Chapel Hill, N.C. Upon completion of the acquisition,  NBC will have
$492 million in assets, 26 branches and 28 ATM locations in North Carolina.

"Acquisitions such as Hillsborough Savings Bank, as well as others transacted in
our  Tennessee  markets in recent  months,  support  our  corporate  strategy of
entering  markets de novo,  with  multiple  supermarket  locations for rapid and
efficient  deposit  and  loan  growth.   The  in-market   acquisitions   provide
traditional  locations  that  act  as  catalysts  for  small  business  banking,
commercial lending and private banking  services," said Thomas M. Garrott,  NCBC
chairman and chief executive officer. "We are especially pleased to team up with
Hillsborough  Savings  Bank,  such a long  standing,  community  bank with great
tradition and deep roots in area since 1913."

"We are very  excited  about our  upcoming  affiliation  with NBC Bank," said D.
Tyson Clayton,  president and chief executive officer of Piedmont  Bancorp.  "We
believe the two organizations complement one another. NCBC is a strong financial
partner that shares our devotion to customer service," he added.
"The  addition  of  Hillsborough  Savings  Bank  should  allow NBC to expand the
delivery of products and services to customers in this dynamic,  rapidly growing
region,"  said  William R. Reed,  Jr.,  NCBC vice  chairman  and senior  banking
officer. "The Hillsborough bank's traditional branch in Durham complements NBC's
five in-store locations there, while the Hillsborough  Savings Bank locations in
Hillsborough and Chapel Hill allow us to enter Orange County with  full-service,
traditional branches for the first time," he said.

NBC Bank, FSB President John G. Stallings,  Jr. added,  "This  combination  will
allow NBC to provide strong  delivery  channels in every corner of the Triangle.
With branches now covering Orange and Durham counties, in addition to our strong
presence  in Wake  County,  we will have a greater  ability to form and  service
customer relationships across the region."

National Commerce  Bancorporation and Piedmont  Bancorp.,  Inc. Announce Certain
Pricing Terms of Previously Announced Acquisition

December  28, 1999 03:13 PM MEMPHIS,  Tenn.,  Dec. 28  /PRNewswire/  -- National
Commerce  Bancorporation NCBC and Piedmont Bancorp.,  Inc. (Amex: PDB) announced
today certain pricing provisions  contained in their previously announced merger
agreement.  ---- The announced  $34.5 million  transaction  value and $12.52 per
share  equivalent  price per share of  Piedmont  common  stock  were  based on a
floating  exchange  ratio so long as NCBC common stock trades within a $20.70 to
$25.30 per share range.  The per share  equivalent price was based on the number
of shares of Piedmont  common  stock and  options to acquire  shares of Piedmont
common  stock  currently  outstanding  as of the date of the  merger  agreement.
Pursuant to the merger agreement,  Piedmont stock options will convert into NCBC
stock options in substantially the same manner as outstanding shares of Piedmont
common stock will convert into shares of NCBC common stock.  The exchange  ratio
will be finally  determined  based on the average  closing  price of NCBC common
stock for the five  trading  day period  ending two days  before  closing of the
acquisition.  If such  average  price is less than  $20.70 per  share,  then the
exchange  ratio will be fixed at  approximately  six tenths  (.60) of a share of
NCBC common stock for each share of Piedmont common stock. If such average price
is more  than  $25.30  per  share,  then  the  exchange  ratio  will be fixed at
approximately  forty-nine one  hundredths  (.49) of a share of NCBC common stock
for each share of Piedmont common stock. SOURCE National Commerce Bancorporation
