balances.

NYBCL and to receive  such  consideration  as may be  determined  to be due with
respect to such Dissenting Shares pursuant to and subject to the requirements of
the NYBCL. If any holder of Dissenting Shares shall have so failed to perfect or
effectively  withdrawn or lost such  holder's  right to dissent from the Merger,

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

          (a)  Immediately  prior to the Effective  Time, CBSI shall cause to be
deposited  with  American  Stock  Transfer & Trust Company (or any other bank or
trust company selected by CBSI and reasonably  acceptable to PBI) (the "Exchange
Agent"), for exchange in accordance with this Article II, such amount of cash as
is  sufficient  to  pay  the  aggregate  Merger  Consideration  into  which  the
outstanding  shares of PBI Common Stock shall be  converted  pursuant to Section
2.2 of this Agreement.  CBSI shall use its  commercially  reasonable  efforts to
cause the Exchange  Agent to mail,  as soon as  practicable  after the Effective
Time but no later than three (3) business days following the Effective  Time, to
all holders of record of PBI Common  Stock,  excluding any holders of Dissenting
Shares,  letters of  transmittal  specifying the procedures for delivery of such
holders'  certificates  formerly  representing  PBI Common Stock to the Exchange
Agent in  exchange  for the  Merger  Consideration  into which the shares of PBI
Common Stock represented by such certificates shall have been converted pursuant
to this  Article II. As soon as  practicable,  after  surrender  to the Exchange
Agent  of  the   certificates  of  PBI  Common  Stock  in  accordance  with  the
instructions of the letter of transmittal,  the Exchange Agent shall  distribute
to the  former  holders  of shares of PBI  Common  Stock a check for the  Merger
Consideration  that each such  holder is  entitled  to receive  pursuant to this
Agreement. In no event shall the holder of any such surrendered  certificates be
entitled to receive  interest  on any  amounts to be received in the Merger.  If
payment of the  Merger  Consideration  is to be made to a Person  other than the
Person in whose name the  surrendered  certificate  is  registered  in the stock
transfer  books of PBI, it shall be a condition of payment that the  certificate
so  surrendered  shall be properly  endorsed  and  otherwise  in proper form for
transfer and the Person  requesting  such exchange  shall have paid all transfer
and other taxes required by reason of the payment of the Merger Consideration to
a Person other than the  registered  holder of the  surrendered

                                       9


certificate or established to the  satisfaction  of the Exchange Agent that such
taxes are not payable.

          (b) At any time following the  expiration of six (6) months  following
the Effective  Time, the Surviving  Corporation  shall be entitled to direct the
Exchange  Agent to deliver  to it any funds  which had been  deposited  with the
Exchange Agent and not disbursed to holders of the PBI Common Stock  (including,
without  limitation,  all  interest  and  other  earnings  on such  funds),  and
thereafter  such holders shall be entitled to look to the Surviving  Corporation
only as general creditors thereof with respect to any Merger  Consideration that
may be payable upon due surrender of their certificates.

          (c) At the Effective  Time,  the stock  transfer books of PBI shall be
closed  and no  transfer  of PBI  Common  Stock  shall  thereafter  be  made  or
recognized.  If, after the Effective Time, certificates representing such shares
are presented for transfer, they shall be cancelled and exchanged for the Merger
Consideration as provided in this Section.

          (d) In the  event  any  certificate  shall  have  been  lost,  stolen,
destroyed  or  mutilated,  upon the making of an  affidavit  of that fact by the
Person claiming such certificate to be lost, stolen, destroyed or mutilated and,
if required by CBSI, the making of an indemnity  agreement in a form  reasonably
requested  by CBSI and/or the posting by such Person of a bond in such amount as

standing  under  the laws of its  incorporation  with full  corporate  power and
authority to own,  lease and operate the properties it purports to own, lease or
operate and to carry on its business as now conducted,  except where the failure
to be in good  standing  or to have  such  power or  authority  would not have a
Material  Adverse  Effect  on PBI.  Each of PBI  and  its  Subsidiaries  is duly
licensed or  qualified  to do  business  in the states of the United  States and
foreign  jurisdictions where its ownership or leasing of property or the conduct
of its business requires such  qualification,  except where the failure to be so
licensed or qualified  would not have a Material  Adverse  Effect on PBI. PBI is
registered  as a savings and loan  holding  company  under the Home Owners' Loan
Act. The certificate or articles of incorporation  and bylaws of PBI and each of
its  Subsidiaries,  copies of which have  previously been furnished to CBSI, are
true,  correct and  complete  copies of such  documents as in effect or the date
hereof.

     3.3 Ownership of PBI Subsidiaries; Capital Structure of PBI Subsidiaries. A
         --------------------------------------------------------------------
true  and  complete  list  of all  of  PBI's  Subsidiaries,  together  with  the
jurisdiction  of  incorporation  of each  Subsidiary  and the percentage of each

                                       11


Subsidiary's  outstanding  capital  stock owned by PBI or another  subsidiary of
PBI, has been Previously  Disclosed.  Except as previously  disclosed,  PBI does
not,  directly  or  indirectly,  own any equity or similar  interest  in, or any
interest  convertible  into or  exchangeable  or exercisable  for, any equity or
similar interest in, any Person.

     3.4 Authorized and Effective Agreement.
         ----------------------------------

          (a) PBI has all requisite  corporate power and authority to enter into
and  perform  all of its  obligations  under  this  Agreement  and  each  of the
Transaction Documents to which it is a party. The execution and delivery of this
Agreement  and each  such  Transaction  Agreement  and the  consummation  of the
transactions  contemplated  hereby  and  thereby  have  been  duly  and  validly
authorized by all necessary  corporate  action in respect thereof on the part of
PBI, except for the  affirmative  vote by the holders of a majority of the votes
cast by the holders of PBI Common Stock  entitled to vote thereon,  which is the
only  shareholder  vote  required  to  approve  the  Merger  pursuant  to  PBI's
certificate  of  incorporation  and bylaws.  The Board of  Directors  of PBI has
approved  and adopted this  Agreement  and the Merger,  and  directed  that this
Agreement be submitted to PBI's  shareholders  for approval at a special meeting
to be held in accordance with this Agreement.  The Board of Directors of PBI has
unanimously  recommended that the shareholders of PBI approve this Agreement and
the Merger.

          (b) This  Agreement  and each  Transaction  Document to which PBI is a
party  have  been  duly  executed  and  delivered  by  PBI  and,   assuming  the
representation  contained in Section  4.2(b)  hereof is true and  correct,  this
Agreement   constitutes  the  legal,  valid  and  binding  obligations  of  PBI,
enforceable  against  PBI  in  accordance  with  its  terms,  except  that  such
enforceability  may be  subject  to  bankruptcy,  insolvency  and other  laws of
general applicability  relating to or affecting creditors' rights and to general
equity principles.

          (c) Neither the execution and delivery by PBI of this Agreement or any
Transaction   Document  to  which  it  is  a  party,  nor  consummation  of  the
transactions  contemplated hereby or thereby,  nor compliance by PBI with any of
the  provisions  hereof or thereof shall (i) conflict with or result in a breach
of any  provision of the  certificate  of  incorporation  or bylaws of PBI, (ii)
assuming the consents and approvals  contemplated  by Section 5.3 hereof and the
consents  and  approvals  which  are  Previously  Disclosed  are duly  obtained,
constitute  or result in a breach of any term,  condition  or  provision  of, or
constitute  a  default  under,  or  give  rise  to  any  right  of  termination,
cancellation or  acceleration  with respect to, or result in the creation of any
lien,  charge or  encumbrance  upon any  property  or asset of PBI or any of its
Subsidiaries  pursuant  to,  any  note,  bond,  mortgage,   indenture,  license,
agreement  or  other  instrument  or  obligation  to  which  PBI  or  any of its
Subsidiaries   is  a  party,  or  (iii)  assuming  the  consents  and  approvals
contemplated  by Section 5.3 hereof and the  consents  and  approvals  which are
Previously Disclosed are duly obtained, conflict with or violate any law, order,
writ, injunction,  decree,  statute, rule or regulation applicable to PBI or any
of its Subsidiaries or their respective assets;  except, in case of clauses (ii)
and  (iii)  above,  for  any  such  breach,   default,   right,   lien,  charge,
encumbrances,  violation or conflict  which,  individually  or in the aggregate,
would not have a Material Adverse Effect on PBI.

                                       12


          (d) Other than as  contemplated  by Section  5.3  hereof,  no consent,
approval or  authorization  of, or declaration,  notice,  filing or registration
with, any governmental or regulatory authority, or any other Person, is required
to be made or  obtained  by PBI or  OFSLA on or  prior  to the  Closing  Date in
connection with the execution, delivery and performance of this Agreement or any
of the Transaction  Documents to which PBI is a party or the consummation of the
transactions  contemplated  hereby or thereby. As of the date hereof, PBI is not
aware of any  reason  that the  condition  set forth in  Section  6.1(b) of this
Agreement would not be satisfied.

     3.5  Regulatory  Filings.  Each of PBI and its  Subsidiaries  has filed all
          -------------------
reports  required by statute or regulation to be filed with any federal or state
bank  regulatory  agency,  and such reports were prepared in accordance with the
applicable statutes, regulations and instructions in existence as of the date of
filing of such reports in all material respects.

     3.6 SEC Documents;  Financial Statements;  Books and Records; Minute Books.
         ----------------------------------------------------------------------
PBI has filed all forms, reports and documents required to be filed with the SEC
since  January  1, 2000.  The SEC  Reports  (i) were  prepared  in all  material
respects  in  accordance  with the  requirements  of the  Securities  Act or the
Exchange  Act,  as the case may be, 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  therein or necessary in
order to make the statements  therein,  in the light of the circumstances  under
which they were made, not misleading.  The PBI Financial Statements filed by PBI
in SEC Documents prior to the date of this Agreement fairly present, and the PBI
Financial  Statements  filed  by PBI in SEC  Documents  after  the  date of this
Agreement will fairly present, the consolidated  financial position of PBI as of
the dates indicated and the consolidated income, changes in shareholders' equity
and cash flows of PBI and its  consolidated  Subsidiaries  for the periods  then
ended and each such financial statement has been or will be, as the case may be,
prepared in conformity with generally accepted accounting  principles applicable
to  financial  institutions  applied  on a  consistent  basis,  except  that the
unaudited  interim  financial  statements  were or are  subject  to  normal  and
recurring year-end adjustments which were not or are not expected to be material
in amount,  and may not contain certain related notes as may be permitted by the
applicable  rules  promulgated by the SEC. The books and records of PBI and each
of its Subsidiaries  fairly reflect in all material respects the transactions to
which it is a party or by which its properties are subject or bound.  Such books
and records have been properly kept and  maintained  and are in compliance  with
all applicable legal and accounting  requirements in all material respects.  The
minute  books of PBI and each of its  Subsidiaries  contain  records  which  are
accurate in all material  respects of all corporate  actions of its shareholders
and Board of Directors (including committees of its Board of Directors).

     3.7 Material Adverse Change. PBI has not, on a consolidated basis, suffered
         -----------------------
any change in its financial  condition,  results of operations or business since
December 31, 2002 which,  individually  or in the aggregate  with any other such
changes, would constitute a Material Adverse Effect with respect to PBI.

     3.8  Absence of  Undisclosed  Liabilities.  Except as set forth in Schedule
          ------------------------------------
3.8, neither PBI nor any of its  Subsidiaries  has any liability  (contingent or
otherwise)  that is  material  to PBI on a  consolidated  basis,  or that,  when
combined  with  all  similar  liabilities,   would  be  material  to  PBI

                                       13

on a  consolidated  basis,  except as disclosed in the PBI Financial  Statements
contained  in an SEC  Document  filed  prior to the date  hereof  and except for
liabilities  incurred in the ordinary  course of business  consistent  with past
practice since March 31, 2003.

     3.9 Properties.  PBI and its  Subsidiaries  have good and marketable  title
         ----------
free and  clear of all  liens,  encumbrances,  charges,  defaults  or  equitable
interests to all of the  properties  and assets,  real and  personal,  which are
material to the business of PBI on a consolidated basis, and which are reflected
on the PBI  Financial  Statements  as of March 31, 2003 or  acquired  after such
date, except (i) liens for taxes not yet due and payable, (ii) pledges to secure
deposits and other liens incurred in the ordinary course of banking  business as
reflected in the books and records of PBI,  (iii) such  imperfections  of title,
easements and encumbrances,  if any, as are not material in character, amount or
extent, and (iv) dispositions and encumbrances for adequate consideration in the
ordinary course of business  consistent with past practice.  All leases pursuant
to which PBI or any of its  Subsidiaries,  as lessee,  leases real and  personal
property which,  individually or in the aggregate,  are material to the business
of PBI on a consolidated  basis are valid and enforceable  against the lessor in
accordance  with their  respective  terms.  All  tangible  property  used in the
business of PBI is in good condition,  reasonable wear and tear excepted, and is
usable in the ordinary course of business consistent with PBI's past practices.

     3.10 Loans.
          -----

          (a) Each loan  reflected as an asset in the PBI  Financial  Statements
(i) is evidenced by notes,  agreements or other evidences of indebtedness  which
are true,  genuine and what they purport to be, and such documents comply in all
material  respects with all applicable laws, rules and regulations,  (ii) to the
extent  secured,  has been secured by valid liens and security  interests  which
have been  perfected,  (iii) is the legal,  valid and binding  obligation of the
obligor named therein, enforceable in accordance with its terms, except that the
enforceability  thereof  may be subject to  bankruptcy,  insolvency,  fraudulent
conveyance  and other laws of general  applicability  relating  to or  affecting
creditors'  rights and to  general  equity  principles,  in each case other than
loans as to which the failure to satisfy the foregoing  standards,  individually
or in the aggregate,  would not have a Material  Adverse Effect on PBI, and (iv)
was solicited,  originated and existed, and will exist at the Effective Time, in
material  compliance  with all  applicable  loan  policies of PBI or OFSLA.  The
information (including electronic information and information contained on tapes
and  computer  disks)  with  respect  to all  loans of PBI and its  Subsidiaries
furnished to CBSI by PBI is, as of the respective dates indicated therein,  true
and complete in all material respects.

          (b) The  allowance  for loan  losses  reflected  on the PBI  Financial
Statements, as of their respective dates, is in all material respects consistent
with the requirements of generally accepted accounting principles to provide for
reasonably  anticipated losses with respect to the loan portfolio of PBI and its
Subsidiaries based upon information available at the time.

     3.11 Tax Matters.
          -----------

                                       14

          (a) PBI and each of its Subsidiaries  have timely filed federal income
tax returns for each year  through  December 31, 2001 and has timely  filed,  or
caused to be filed,  all other Tax Returns  required to be filed with respect to
PBI or any of its  Subsidiaries.  All Taxes due by or on behalf of PBI or any of
its  Subsidiaries  have been paid or adequate  reserves have been established on
the PBI Financial  Statements for the payment of such Taxes. Neither PBI nor any
of its Subsidiaries  will have any liability for any such Taxes in excess of the
amounts so paid or  reserves  or  accruals  so  established,  except  where such
liability would not,  individually or in the aggregate,  have a Material Adverse
Effect on PBI.

          (b) All Tax  Returns  filed  by PBI and each of its  Subsidiaries  are
complete  and  accurate  in all  material  respects.  Neither PBI nor any of its
Subsidiaries  is  delinquent  in the  payment  of any Tax,  and none of them has
requested  any extension of time within which to file any Tax Returns which have
not since been filed. No audit examination, deficiency, adjustment, refund claim
or  litigation  with  respect to Tax  Returns,  paid Taxes,  unpaid Taxes or Tax
attributes  of PBI has been  proposed,  asserted  or  assessed  (tentatively  or
otherwise).  There are  currently no agreements in effect with respect to PBI or
any of its  Subsidiaries  to extend the period of limitations for the assessment
or collection of any Tax.

          (c) Neither the transactions  contemplated  hereby nor the termination
of the employment of any employees of PBI prior to or following  consummation of
the  transactions  contemplated  hereby  will  result  in  PBI  or  any  of  its
Subsidiaries  (or any successor  thereof)  making or being  required to make any
"excess parachute payment" as that term is defined in Section 280G of the Code.

          (d)  Except  as  Previously  Disclosed,  neither  PBI  nor  any of its
Subsidiaries is a party to any agreement providing for the allocation or sharing
of, or indemnification for, Taxes.

          (e)  Except  as  Previously  Disclosed,  neither  PBI  nor  any of its
Subsidiaries  is  required  to include in income any  adjustment  in any taxable
period ending after the date hereof pursuant to Section 481(a) of the Code.

          (f) Neither PBI nor any of its  Subsidiaries  has  executed or entered
into any written  agreement with any Tax authority  conceding or agreeing to any
treatment of Taxes or Tax attributes, including, without limitation, an Internal
Revenue  Service Form 870 or Form 870-AD,  closing  agreement or special closing
agreement,  affecting PBI or any of its Subsidiaries pursuant to Section 7121 of
the Code or any predecessor provision thereof or any similar provision of state,
local or foreign  law,  which  agreement  would  have a  material  impact on the
calculation of the Taxes of CBSI or any of its Subsidiaries  after the Effective
Time.

     3.12 Employee Benefit Plans.
          ----------------------

          (a) Schedule  3.12(a)  hereto sets forth a true and  complete  list of
each PBI Plan. For purposes of this Section 3.12, the term "PBI Plan" means each
bonus, deferred  compensation,  incentive  compensation,  stock purchase,  stock
option,  severance pay,  medical,  life or other insurance,  profit-sharing,  or
pension plan, program, agreement or arrangement, and each other employee benefit
plan, program, agreement or arrangement, sponsored, maintained or

                                       15


contributed  to or  required  to be  contributed  to by PBI or by any  trade  or
business, whether or not incorporated,  that together with PBI would be deemed a
"single  employer" under Section 414 of the Code (an "ERISA  Affiliate") for the
benefit of any employee or director or former employee or former director of PBI
or any ERISA Affiliate of PBI.

          (b) With respect to each of the PBI Plans,  PBI has made  available to
CBSI true and complete  copies of each of the following  documents:  (a) the PBI
Plan and related  documents  (including  all amendments  thereto);  (b) the most
recent annual reports,  financial statements, and actuarial reports, if any; (c)
the most recent summary plan description, together with each summary of material
modifications,  required  under  ERISA  with  respect  to such  PBI Plan and all
material  communications relating to each such PBI Plan; and (d) the most recent
determination letter received from the IRS with respect to each PBI Plan that is
intended to be qualified  under the Code and all material  communications  to or
from  the IRS or any  other  governmental  or  regulatory  agency  or  authority
relating to each PBI Plan.

          (c) To the knowledge of PBI, no liability  under Title IV of ERISA has
been incurred by PBI or any ERISA  Affiliate of PBI that has not been  satisfied
in full,  and no condition  exists that  presents a material  risk to PBI or any
ERISA  Affiliate  of PBI of incurring a liability  under such Title,  other than
liability  for premium  payments to the Pension  Benefit  Guaranty  Corporation,
which premiums have been or will be paid when due.

          (d) Neither PBI nor, to the  knowledge of PBI, any ERISA  Affiliate of
PBI, nor any of the PBI Plans,  nor, to the  knowledge of PBI, any trust created
thereunder, nor any trustee or administrator thereof has engaged in a prohibited
transaction  (within the meaning of Section 406 of ERISA and Section 4975 of the
Code)  in  connection  with  which  PBI  or any  ERISA  Affiliate  of PBI  could
reasonably be expected to,  either  directly or  indirectly,  incur any material
liability or material cost.

          (e) Full  payment has been made,  or will be made in  accordance  with
Section 404(a)(6) of the Code, of all amounts that PBI or any ERISA Affiliate of
PBI is required  to pay under  Section 412 of the Code or under the terms of the
PBI Plans.

          (f)  Except as  Previously  Disclosed,  the fair  market  value of the
assets  held under each PBI Plan that is subject to Title IV of ERISA  equals or
exceeds the actuarial  present value of all accrued benefits under each such PBI
Plan. No PBI Plan subject to Section 412 of the Code has an "accumulated funding
deficiency"  within the  meaning of Section  412(a) of the Code.  No  reportable
event under  Section  4043 of ERISA has  occurred  with  respect to any PBI Plan
other  than  any  reportable  event  occurring  by  reason  of the  transactions
contemplated  by this Agreement or a reportable  event for which the requirement
of notice to the PBGC has been waived.

          (g)  Except  as  Previously  Disclosed,  none  of the PBI  Plans  is a
"multiemployer pension plan," as such term is defined in Section 3(37) of ERISA,
a "multiple  employer  welfare  arrangement," as such term is defined in Section
3(40) of ERISA,  or a single  employer  plan  that has two or more  contributing
sponsors, at least two of whom are not under common control,  within the meaning
of Section 4064(a) of ERISA.

                                       16


          (h) A favorable  determination  letter has been issued by the Internal
Revenue  Service  with  respect to each of the PBI Plans that is  intended to be
"qualified"  within the meaning of Section 401(a) of the Code to the effect that
such plan is so qualified and, to the knowledge of PBI, no condition exists that
could  adversely  affect the qualified  status of any such PBI Plan. Each of the
PBI Plans  that is  intended  to satisfy  the  requirements  of  Section  125 or
501(c)(9) of the Code satisfies such requirements in all material respects. Each
of the PBI Plans has been operated and administered in all material  respects in
accordance  with its terms and  applicable  laws,  including  but not limited to
ERISA and the Code.

          (i)  There  are no  actions,  suits  or  claims  pending,  or,  to the
knowledge of PBI,  threatened  or  anticipated  (other than  routine  claims for
benefits) against any PBI Plan, the assets of any PBI Plan or against PBI or any
ERISA  Affiliate  of PBI with  respect  to any PBI Plan.  There is no  judgment,
decree,  injunction,  rule or order of any court, governmental body, commission,
agency  or  arbitrator  outstanding  against  or in favor of any PBI Plan or any
fiduciary  thereof,  other  than rules of  general  applicability.  There are no
pending  or,  to the  knowledge  of  PBI,  threatened  audits,  examinations  or
investigations by any governmental body,  commission or agency involving any PBI
Plan.

          (j) Except as set forth in Schedule  3.12(j),  the consummation of the
transactions  contemplated  by this  Agreement  will not result in, and is not a
precondition  to, (i) any  current or former  employee or director of PBI or any
ERISA  Affiliate  of  PBI  becoming  entitled  to  severance  pay,  unemployment
compensation  or any  similar  payment,  (ii)  any  acceleration  in the time of
payment or vesting,  or increase in the amount,  of any  compensation due to any
such current or former  employee or director,  or (iii) any renewal or extension
of the term of any  agreement  regarding  compensation  for any such  current or
former employee or director.

          (k) PBI shall take,  and/or PBI shall  cause  OFSLA to take,  all such
action as is necessary or reasonably  appropriate to withdraw from and terminate
OFSLA's  participation  in the multiple  employer  defined  benefit pension plan
known as the  "Financial  Institutions  Retirement  Fund" as of July 1, 2003, in
accordance  with the terms thereof,  contributing  such amounts to the trust for
the plan as may be required by the terms thereof,  or by the sponsor thereof, as
a result of such withdrawal.

          (l) Prior to the  Effective  Time,  PBI shall  take,  and/or PBI shall
cause OFSLA to take,  all such action as is necessary or reasonably  appropriate
to withdraw from and terminate  OFSLA's  participation in the multiple  employer
Code section  401(k)/profit  sharing plan known as the  "Financial  Institutions
Thrift  Plan" as of or prior to the Closing  Date in  accordance  with the terms
thereof.

          (m) To the extent  reasonably  requested to do so by CBSI or Community
Bank,  prior to the  Effective  Time,  PBI  shall  take all  such  action  as is
necessary or reasonably  appropriate to terminate all employee  welfare  benefit
plans (as defined in ERISA section 3(1)) maintained by PBI as of a date prior to
the Effective Time.

Bank has adopted, and Community Bank has implemented,  an anti-money  laundering
program that meets the  requirements in all material  respects of Section 352 of
the USA Patriot Act and the regulations thereunder.

     4.8 Agreements  with and Examination by Banking  Authorities.  Neither CBSI
         --------------------------------------------------------
nor any of its  Subsidiaries  is a party to any  commitment,  letter (other than
letters  addressed  to regulated  depository  institutions  generally),  written
agreement,  memorandum  of  understanding,  order to cease and desist  with,  is
subject to any order or  directive  specifically  naming or referring to CBSI or
any of its  Subsidiaries by, has been required to adopt any board resolution by,
any  federal  or state  governmental  entity  charged  with the  supervision  or
regulation  of banks or bank holding  companies  or engaged in the  insurance of
bank deposits which is currently in effect and restricts  materially the conduct
of its business,  or in any manner  relates to its capital  adequacy,  loan loss
allowances  or  reserves,  ability to perform  its  obligations  hereunder,  and
neither CBSI nor any of its Subsidiaries has received written  notification from
any such  federal  or state  governmental  entity  that any such  Person  may be
required to enter into, or otherwise be subject to, any such commitment, letter,
written agreement, memorandum of understanding or cease or desist order. Neither
CBSI nor any of its Subsidiaries has been informed by any bank regulator that it
is  contemplating  issuing or requesting any such order,  directive,  agreement,
memorandum of understanding,  commitment letter or similar  submission.  Neither
CBSI nor any of its  Subsidiaries  is a party to any  agreement  or  arrangement
entered  into in  connection  with  the

                                       25


consummation  of a federally  assisted  acquisition of a depository  institution
pursuant  to  which  CBSI or any of its  Subsidiaries  is  entitled  to  receive
financial assistance or indemnification from any governmental agency. Except for
the Bank  Examinations  conducted by the Federal Reserve Board, the FDIC, or the
OCC in the regular  course of the business of CBSI and its  Subsidiaries,  since
January 1, 2001, no bank  regulator has initiated any proceeding or, to the best
knowledge of CBSI,  investigation into the business or operations of the CBSI or
any of its  Subsidiaries.  CBSI and its Subsidiaries  have resolved all material
violations,  criticisms or exceptions by any bank  regulator with respect to any
Bank Examination.

     5.1 PBI  Shareholders'  Meeting.  PBI shall call and give notice of the PBI
         ---------------------------
Shareholders'  Meeting as promptly as  practicable  after the 30th day following
the date a preliminary PBI Proxy Statement  contemplated by Section 5.2 is filed
with the SEC (unless the PBI Proxy Statement  becomes subject to SEC review,  in
which  case no later  than the 20th day  after the SEC  notifies  PBI that it is
satisfied with the revisions made pursuant to, and PBI's response in respect of,
SEC's comments and that it has no further  comments),  for the purpose of voting
upon the approval of this Agreement, and PBI shall use all reasonable efforts to
hold  the PBI  Shareholders'  Meeting  as soon as  practicable,  subject  to the
applicable  notice  requirements  under the NYBCL,  provided that PBI shall have
received an opinion from its financial  advisors,  dated within five (5) days of
the  mailing  date of the PBI Proxy  Statement,  that the  Merger is fair to PBI
Shareholders  from a financial  point of view,  which  opinion PBI shall use all
commercially  reasonable  efforts  to cause to be  issued  as  expeditiously  as
possible. Subject to the fiduciary duties of the Board of Directors of NYBCL, as
determined after  consultation with outside counsel and financial  advisors,  if
any,  (i) the Board of Directors of PBI shall  recommend  that the  shareholders
vote in favor of the approval of this Agreement, and (ii) PBI shall solicit from
its  shareholders  proxies in favor of approval of this Agreement and shall take
all other action  necessary or desirable to secure the vote of  shareholders  to
obtain such approval. Notwithstanding any withdrawal,  modification or change in
any  recommendation of the Board of Directors of PBI, to the extent permitted by
law,  PBI agrees to hold the PBI  Shareholders'  Meeting  within the time period
specified above.

     5.2 PBI Proxy  Statement.  Within 60 days after the date hereof,  PBI shall

shall  cooperate in the  preparation of the PBI Proxy  Statement to be mailed to
the  shareholders  of PBI in connection  with  obtaining  their approval of this
Agreement  and the Merger.  PBI will  advise  CBSI,  promptly  after it receives
notice  thereof,  any request by the SEC for the  amendment or supplement of the
PBI Proxy Statement or for additional information.  If, at any time prior to the
Effective Time, any event or circumstance relating to a party to this Agreement,
or its directors, officers or 5% or greater shareholders, shall be discovered by
such party that pursuant to the Exchange Act should be set forth in an amendment
or a supplement to the PBI Proxy Statement, such party shall promptly notify the
other party.

     5.3  Applications.  As promptly as practicable,  but no later than 30 days,
          ------------
after the date  hereof,  and after a  reasonable  opportunity  for review by the
other party and its counsel, CBSI, Merger Sub and PBI shall submit any requisite
applications   for  prior   approval  of,  and  notices  with  respect  to,  the
transactions  contemplated  herein to the OCC,  the OTS and the Federal  Reserve
Board,  and each of the parties hereto shall,  and shall cause its  Subsidiaries
to,  submit any  applications,  notices or other  filings to any other  state or
federal government agency, department or body, the approval of which is required
or desirable for  consummation of the Merger,  the Bank Merger or the Short-Form
Merger.  PBI, on one hand,  and CBSI and Merger  Sub,  on the other  hand,  each
represents and warrants to the other that all information  concerning it and its
directors,  officers,  shareholders and Subsidiaries  included (or submitted for
inclusion) in any such  application  and furnished by it shall be true,  correct
and  complete in all  material  respects.  Each party agrees to consult with the
other parties with respect to obtaining all necessary approvals and consents and
each will keep the other  apprised  of the  status of matters  relating  to such
approvals and consents.

     5.4 Best Efforts.
         ------------

          (a)  Subject  to the terms and  conditions  of this  Agreement,  CBSI,
Merger Sub and PBI shall each use  reasonable  best efforts in good faith to (i)
furnish such  information as may be required or desirable in connection with the
preparation of the documents referred to in Sections 5.2 and 5.3 above, and (ii)
take or cause to be taken all action necessary or desirable on its part so as to
permit  consummation of the Merger, the Bank Merger and the Short-Form Merger at
the earliest possible date,  including,  without  limitation,  (1) obtaining the
consent  or  approval  of Person  whose  consent or  approval  is  required  for
consummation of the transactions  contemplated  hereby,  provided that PBI shall
not agree to make any payments or  modifications  to  agreements  in  connection
therewith  without the prior written consent of CBSI, which consent shall not be
unreasonably  withheld, and (2) requesting the delivery of appropriate opinions,
consents and letters from its counsel and independent  auditors.  Subject to the
terms and  conditions of this  Agreement,  no party hereto shall take or fail to
take,  or cause or permit its  Subsidiaries  to take or fail to take,  or to the
best of its  ability  permit  to be taken or  omitted  to be taken by any  third
party,  any action that would  substantially  impair the prospects of completing
the Merger,  the Bank Merger and the Short-Form  Merger,  that would  materially
delay such completion.

          (b) Each party hereto  shall give prompt  notice to the other party of
(i) the  occurrence,  or  failure to occur,  of any event  which  occurrence  or
failure  would be  reasonably  likely to cause any  representation  or  warranty
contained in this Agreement to be untrue or inaccurate at any time from the date
hereof to the Closing Date such that the condition  set forth in Section  6.2(a)
or  6.3(a),  as  applicable,  would  not be met if  such  failure  to be true or
accurate  were to occur  or be  continuing  on the  Closing  Date,  and (ii) any
material failure of any party to comply with or satisfy any covenant,  condition
or agreement to be complied  with or satisfied by it  hereunder,  and each party
shall use all reasonable best efforts in good faith to remedy such failure.

          (c) From the date of this Agreement through the Effective Time, to the
extent  permitted by law, PBI shall cause OFSLA to provide  such  assistance  to
Community  Bank as

                                       27


reasonably  necessary  for  Community  Bank to prepare  for the  conversion  and
transfer in connection  with the Merger all  information  concerning  the loans,
deposits and other assets and  liabilities  of OFSLA into  Community  Bank's own
data processing system, with a view to facilitating the integration of Community
Bank's and OFSLA's systems and otherwise  combining Community Bank's and OFSLA's
operations  upon  consummation  of the Merger.  Such  assistance  shall  include
providing  Community  Bank with computer file  instructions  with respect to the
information in its data processing  system  regarding the assets and liabilities
of OFSLA,  together  with  operational  procedures  designed  to  implement  the
transfer  of  such   information   to   Community   Bank,   provided   that  the
confidentiality  of customer  information  shall be preserved and no information
shall  be  transferred  until  the  Effective  Time.  After  execution  of  this
Agreement,  OFSLA and Community Bank shall each designate an individual to serve
as liaison  concerning  the transfer of data  processing  information  and other
similar operational matters.  All out-of-pocket  expenses reasonably incurred by
PBI or OFSLA,  and approved in writing in advance by CBSI, in complying with the
covenants set forth in Section 5.4(c) shall be reimbursed  promptly by CBSI upon
the provision of adequate written evidence of such expenses.

          (d) Each party  shall  provide,  and shall  request  its  auditors  to
provide, the other party with such historical financial information regarding it
(and  related  audit  reports and  consents)  as the other party may  reasonably
request for disclosure purposes under the Securities Laws.

     5.5 Investigation and  Confidentiality.  PBI, CBSI and Merger Sub each will
         ----------------------------------
keep the other  advised of all  material  developments  relevant  to its and its
Subsidiaries'  businesses and to consummation of the  transactions  contemplated
herein.  PBI,  CBSI and  Merger  Sub  each  may  make or  cause to be made  such
investigation  of the financial  and legal  condition of the other as such party
reasonably  deems  necessary or advisable in  connection  with the  transactions
contemplated  herein,  provided,  however,  that  such  investigation  shall  be
                       --------   -------
reasonably   related  to  such   transactions  and  the  party  conducting  such
investigation  shall use its reasonable best efforts to minimize any disruptions
to the operations of the other party.  CBSI, Merger Sub and PBI agree to furnish
the  other  and  the  other's  advisors  with  such  financial  data  and  other
information  with  respect to its business  and  properties  as such other party
shall from time to time reasonably  request.  No investigation  pursuant to this
Section 5.5 shall affect or be deemed to modify any  representation  or warranty
made by, or the  conditions to the  obligations to consummate the Merger of, any
party  hereto.  Each party  hereto shall hold all  information  furnished by the
other party or any of such party's  Subsidiaries or representatives  pursuant to
this  Agreement  in  confidence  and  in  accordance  with  the  confidentiality
agreement  dated  July 3,  2002,  between  PBI and  CBSI  (the  "Confidentiality
Agreement").

     5.6 Press Releases and Other Public  Disclosures.  PBI and CBSI shall agree
         --------------------------------------------
with each other as to the form and  substance  of any press  release  related to
this Agreement or the transactions  contemplated  hereby,  and shall consult and
agree with each other as to the form and  substance of other public  disclosures
related  thereto,   including  without   limitation,   any  communications  with
securities market professionals and investors,  provided,  however, that nothing
contained herein shall prohibit any party,  following  notification to the other
party,  from making any  disclosure  which is required by applicable law or NYSE
rules.

                                       28

this Agreement or consented to or approved in writing by the other party hereto,

reasonable best efforts to preserve its properties,  business and  relationships
with customers, employees and other persons.

                                       30


     5.8 Certain  Policies.  Immediately prior to the Effective Time, PBI shall,
         -----------------
consistent with generally accepted accounting principles and on a basis mutually
satisfactory  to it and CBSI,  modify and change its loan,  litigation  and real
estate  valuation  policies and practices  (including loan  classifications  and
levels of reserves) so as to be applied on a basis that is consistent  with that
of CBSI.  Prior to the Effective Time, PBI and CBSI shall review the adequacy of
reserves for loan losses  currently  established by PBI and, if deemed warranted
by both parties under generally accepted accounting  principles,  PBI shall make
mutually  acceptable  changes to such  reserves.  Following the approval of this
Agreement by the shareholders of PBI and the receipt of all requisite regulatory
approvals  for the  Merger,  PBI shall  cooperate  with CBSI in planned  actions
discussed as part of the due diligence process which are designed to improve the
short and long-term  profitability  of PBI and eliminate or reduce any potential
earnings per share dilution of CBSI upon  consummation of the Merger,  including
but not limited to those actions set forth on Schedule 5.8 hereto. No additional
provision  for loan and real estate  owned taken by PBI pursuant to this Section
5.8 at the  request of CBSI,  shall be deemed in and of itself to be a breach or
violation  of  any  representation,   warranty,  covenant,  condition  or  other
provisions of this Agreement.

     5.9 Closing;  Articles of Merger.  The  transactions  contemplated  by this
         ----------------------------
Agreement shall be consummated at a closing to be held at the offices of the law
firm of Bond,  Schoeneck & King,  PLLC, One Lincoln Center,  Syracuse,  New York
13202 on the first business day, or other  mutually  agreeable  time,  following
satisfaction or waiver of the conditions to consummation of the Merger set forth
in Article VI hereof.

     5.10 Employee Benefits.
          -----------------

          (a) CBSI or its Subsidiaries  shall offer continued  employment to the
current  employees of PBI or any of its  Subsidiaries,  and those  employees who
accept such offer to continue as employees of CBSI or its Subsidiaries after the
Effective  Time  shall  (i) for a one  year  period  immediately  following  the
Effective  Time,  receive  compensation  that is no less  than  what  they  were
receiving  on the date  hereof from PBI,  and be  entitled  to receive  employee
benefits,  as a whole and  subject  to  clause  (ii) of this  sentence,  no less
favorable than those received by CBSI's or its Subsidiaries' other employees who
are similarly  situated,  and (ii) be given credit for past service with PBI for
purposes of determining  eligibility  for and vesting of employee  benefits (but
not for pension  benefit  accrual  purposes)  under all  welfare and  retirement
programs  maintained  by  CBSI  or its  Subsidiaries  in  which  such  employees
participate  following  the Merger.  Nothing  contained in this Section  5.10(a)
shall be construed to guarantee continued  employment of any employees of PBI or
any of its  Subsidiaries,  or to prevent CBSI or its Subsidiaries  from changing
the amount of  compensation  paid to any such  employees  (other than within the
one-year  period  described in clause (i) of the first  sentence of this Section
5.10(a)) or to modify, amend or supplement any employee benefits offered by CBSI
or its Subsidiaries, in each case except as otherwise provided by applicable law
or the terms of an existing  employment  contract.  CBSI acknowledges and agrees
that the  consummation  of the Merger  constitutes a Change of Control,  as such
term is used in each of the Executive Employment Agreements,  and CBSI agrees to
cause Community Bank, as the surviving entity of the Bank Merger, to comply with
the requirements of each of the Executive Employment Agreements.

                                       31


          (b) Except as otherwise set forth herein, prior to the Effective Time,
PBI shall take all actions that may be  reasonably  requested by CBSI in writing
upon advance  notice of not less than 30 days with respect to (i) causing one or
more PBI Plans to terminate as of the Effective Time or for benefit  accrual and
entitlements to cease as of the Effective Time, (ii) causing the continuation on
and after the Effective Time of any contract,  arrangement  or insurance  policy
relating to any PBI Plan for such period as may be requested  by CBSI,  or (iii)
cooperating  with CBSI to  facilitate  the  merger of any PBI Plan into any CBSI
Plan as of or following the Effective Time.

          (c) The ESOP shall be  terminated  as of, or prior to,  the  Effective
Time.  As of the  Effective  Time,  all  shares  held by the PBI  ESOP  shall be
converted into the right to receive the Merger  Consideration in respect of each
share of PBI Common Stock. As soon as administratively practicable following the
Effective Time all  outstanding  indebtedness of the PBI ESOP shall be repaid in
full, in accordance with Section  5.10(c) of the ESOP and the balance  remaining
with  respect  to  unallocated  shares  previously  held by the  ESOP  shall  be
allocated and  distributed to ESOP  participants  as provided in the ESOP and in
accordance  with  applicable  law  and  regulations,  subject  to  receipt  of a
favorable  determination  letter from the  Internal  Revenue  Service and unless
otherwise required by applicable law.  Notwithstanding  anything in this Section
5.10(c) to the contrary,  distributions  may be made from the ESOP to terminated
employees  of PBI or OFSLA as soon as  administratively  practicable  after  the
determination  of final  allocations and the receipt of a  determination  letter
from the IRS,  unless CBSI  determines  that it is  appropriate  to make earlier
distributions.

          (d) (1) In the event of any threatened or actual claim,  action, suit,
proceeding  or  investigation,   whether  civil,   criminal  or  administrative,
including,  without  limitation,  any such claim,  action,  suit,  proceeding or
investigation in which any person (the  "Indemnified  Party") who is now, or has
been at any time prior to the date of this  Agreement,  or who becomes  prior to
the  Effective  Time, a director or officer of PBI is, or is  threatened  to be,
made a party  based in whole or in part on, or  arising  in whole or in part out
of, or  pertaining  to (i) the fact  that he is or was a  director,  officer  or
employee of PBI or any of its Subsidiaries, or (ii) this Agreement or any of the
transactions contemplated hereby, whether in any case asserted or arising before
or after the Effective Time, the parties hereto agree to cooperate and use their
best efforts to defend  against and respond  thereto.  For a period of six years
after the Effective Time, CBSI shall indemnify and hold harmless, to the fullest
extent permitted by law, each such Indemnified Party against any losses, claims,
damages, liabilities,  costs, expenses (including reasonable attorney's fees and
expenses in advance of the final disposition of any claim,  suit,  proceeding or
investigation to each  Indemnified  Party to the fullest extent permitted by the
DGCL upon receipt of any undertaking required by the DGCL), judgments, fines and
amounts paid in  settlement  in  connection  with any such  threatened or actual
claim, action, suit,  proceeding or investigation,  and in the event of any such
threatened or actual claim, action, suit,  proceeding or investigation  (whether
asserted or arising before or after the Effective Time), the Indemnified Parties
may retain counsel reasonably satisfactory to them after consultation with CBSI;
provided,  however,  that (1) CBSI shall  have the right to assume  the  defense
thereof with counsel reasonably  acceptable to the Indemnified  Parties and upon
such assumption CBSI shall not be liable to any Indemnified  Party for any legal
expenses of other  counsel or any other  expenses  subsequently  incurred by any
Indemnified  Party in connection with the defense  thereof,

                                       32


except  that if CBSI  elects  not to assume  such  defense  or  counsel  for the
Indemnified  Parties reasonably  advises the Indemnified  Parties that there are
issues  which raise  conflicts  of  interest  between  CBSI and the  Indemnified
Parties,  the Indemnified Parties may retain counsel reasonably  satisfactory to
them after notification,  and CBSI shall pay the reasonable fees and expenses of
such counsel for the Indemnified  Parties;  (2) CBSI shall be obligated pursuant
to this  paragraph  to pay for  only  one firm of  counsel  for all  Indemnified
Parties;  (3) CBSI shall not be liable for any settlement  effected  without its
prior written consent, which consent shall not be unreasonably withheld, and (4)
CBSI shall have no obligation  hereunder to any Indemnified  Party when and if a
court  of  competent   jurisdiction   shall  ultimately   determine,   and  such
determination shall have become final and nonappealable, that indemnification of
such  Indemnified  Party in the  manner  contemplated  hereby is  prohibited  by
applicable law. Any  Indemnified  Party wishing to claim  indemnification  under
this Section  5.10(d),  upon  becoming  aware of any such claim,  action,  suit,
proceeding or investigation,  shall promptly notify CBSI thereof,  provided that
the failure of any  Indemnified  Party to so notify CBSI shall relieve it of its
obligations  to indemnify  hereunder to the extent that such failure  materially
prejudices CBSI.

               (2)  CBSI  agrees  that all  rights  to  indemnification  and all
limitations  on  liability  existing  in favor of the  directors,  officers  and
employees  of PBI and any of its  Subsidiaries  as provided in their  respective
certificates  of  incorporation,  bylaws or similar  governing  documents  as in
effect as of the date of this Agreement with respect to matters  occurring prior
to the Effective Time shall survive the Merger, and shall continue in full force
and effect, and shall be honored by such entities or their respective successors
as if they  were  the  indemnifying  party  thereunder,  without  any  amendment
thereto, for a period of six years from the Effective Time.

               (3)  CBSI  will  use its  reasonable  best  efforts  directly  or
indirectly to cause the persons who served as directors or officers of PBI on or
before  the  Effective  Time to be  covered  by PBI's  existing  directors'  and
officers' liability insurance policy (provided that CBSI may substitute therefor
policies  of at  least  the same  coverage  and  amounts  containing  terms  and
conditions  which are not less  advantageous  than such  policy) but in no event
shall any insured  person be entitled  under this Section to insurance  coverage
more  favorable  than that  provided to him or her in such  capacities as of the
date hereof with respect to acts or omissions  resulting  from their  service as
such on or prior to the Effective Time.  Such insurance  coverage shall commence
at the  Effective  Time and will be provided  for a period of no less than three
years after the Effective Time; provided,  however,  that in no event shall CBSI
be required to expend  more than 200% of the current  amount  expended by PBI to
maintain or procure insurance  coverage pursuant hereto (the "Maximum  Amount").
If the amount of  premiums  necessary  to  maintain  or procure  said  insurance
coverage exceeds the Maximum Amount,  CBSI shall use its reasonable best efforts
in its good faith  discretion  to  maintain  the most  advantageous  policies of
directors' and officers' liability  insurance  obtainable for a premium equal to
the  Maximum  Amount.  PBI  agrees to renew any such  existing  insurance  or to
purchase any  "discovery  period"  insurance  provided for  thereunder at CBSI's
request.

               (4) In the event  that CBSI or any of its  successors  or assigns
(i)  consolidates  with or  merges  into any other  Person  and shall not be the
continuing  or  surviving  entity  of  such  consolidation  or  merger,  or (ii)
transfers or conveys all or  substantially  all of its

                                       33


properties  and assets to any  Person,  then,  in each such case,  to the extent
necessary, proper provisions shall be made so that the successors and assigns of
CBSI assume the obligations set forth in this Section 5.10(d).

               (5) The provisions of this Section 5.10(d) are intended to be for
the benefit of, and shall be enforceable by, each  Indemnified  Party and his or
her representatives.

     5.11 Advisory Board.
          --------------

          (a) Promptly  following  the  Effective  Time,  CBSI shall cause to be
formed a six-member  advisory board (the "Advisory Board") comprised of the five
members of the Board of Directors of PBI, and the President and Chief  Executive
Officer of CBSI,  the function of which is to advise  Community Bank on deposit,
lending and  financial  services  activities  in PBI's former market area and to
insure a smooth  transition of business  relationships  in  connection  with the
Merger and the continued development of business  relationships  throughout such
market area.  Each member of the Advisory  Board,  other than the  President and
Chief  Executive  Officer of CBSI,  shall be granted  500  restricted  shares of
common stock of CBSI,  one-half of which shares shall vest after the  completion
of each year of service on the Advisory Board, in  consideration  for his or her
services on the Advisory Board for a two-year term following the Effective Time.
In the  event  that any  member  of the  Advisory  Board  ceases to serve on the
Advisory Board prior to the expiration of its two-year term for any reason,  any
restricted  shares which had not  theretofore  vested shall be forfeited by such
member. The Advisory Board shall meet no more than six times per year.

          (b) If at any time  during the period  commencing  with the  Effective
Time,  and  ending  on the date  immediately  following  the  date on which  the
Advisory Board terminates,  the shares of CBSI's common stock are changed into a
different  number  or  class  of  shares  by  reason  of  any  reclassification,
recapitalization, stock split, combination, exchange of shares, or readjustment,
or a stock  dividend  thereon is declared with a record date within said period,
the number  and/or class of  restricted  shares  granted to the  Advisory  Board
members  under this  section  will be  adjusted  to take into  account  any such
reclassification,   recapitalization,   stock  split,   combination,   exchange,
readjustment,  or stock dividend.  In addition, if at any time during the period
described  above,  CBSI  consummates a transaction  pursuant to which (i) CBSI's
corporate  existence  will be  terminated  through a  statutory  merger  with or
transfer of substantially  all of its assets to another  corporation,  (ii) CBSI
exchanges  substantially  all of its common stock with capital  stock of another
corporation  as part of a plan  under  which  CBSI  will  be  liquidated  by the
transferee,  or  (iii)  CBSI  will be  liquidated,  then in each  such  case any
unvested  shares  of  restricted   stock  granted  under  Section  5.11(a)  will
automatically  vest  without the  requirement  of further  action by any Person,
effective immediately prior to the consummation of such transaction.

     5.12 Takeover  Laws. No party hereto shall take any action that would cause
          --------------
the  transactions  contemplated  by  this  Agreement  or any of the  Transaction
Documents to be subject to the  requirements  imposed by any  Takeover  Law, and
each of them shall take all  necessary  steps  within its  control to exempt (or
ensure the continued  exemption of) all such transactions  from, or if necessary
challenge the validity or applicability of, any applicable  Takeover Law, as

                                       34


now or hereafter in effect. For purposes of this Section,  "Takeover Laws" shall
mean Section 912 of the NYBCL.

     5.13 No Solicitation.
          ---------------

          (a) Subject to Section 5.13(b) hereof, from and after the date of this
Agreement  until the earlier of the Closing or the termination of this Agreement
in accordance with its terms, neither PBI nor any Person acting on behalf of PBI
shall, directly or indirectly,  (a) solicit,  initiate or respond to discussions
or engage  in  negotiations  with any  Person  (whether  such  negotiations  are
initiated by PBI or otherwise) or take any other action  intended or designed to
facilitate the efforts of any Person,  other than CBSI, relating to the possible
acquisition, recapitalization or other business combination involving PBI or any
of its  Subsidiaries  (whether  by way of merger,  purchase  of  capital  stock,
purchase of assets or otherwise) or any material portion of its capital stock or
assets (with any such efforts by any such Person,  including a firm  proposal to
make such an acquisition, to be referred to as "Takeover Proposal"), (b) provide
non-public  information  with respect to PBI or any of its  Subsidiaries  to any
Person,  other than CBSI and its  professional  advisors  or PBI's  professional
advisors,  or (c) enter  into an  agreement  with any  Person,  other than CBSI,
providing  for a  possible  Takeover  Proposal.  If PBI  receives  any  offer or
proposal  relating to a Takeover  Proposal,  PBI shall  immediately  notify CBSI
thereof,  including  information as to the identity of the party making any such
offer or proposal and the specific terms of such offer or proposal,  as the case
may be.

          (b) (i) Notwithstanding  anything to the contrary contained in Section
5.13(a), prior to the Closing or the termination of this Agreement in accordance
with its terms, PBI may, to the extent the Board of Directors of PBI determines,
in good faith, after  consultation with outside legal counsel,  that the Board's
fiduciary duties require it to do so, participate in discussions or negotiations
with, and, subject to the requirements of Section  5.13(c),  furnish  non-public
information, and afford access to the properties, books or records of PBI or any
of its  Subsidiaries  to any Person  after such Person has  delivered  to PBI in
writing,  an unsolicited bona fide Takeover  Proposal with respect to PBI or any
of its Subsidiaries  (which has not been withdrawn) which the Board of Directors
of PBI in its good faith  judgment  determines,  after  reasonable  inquiry  and
consultation with its financial advisor (i) would be reasonably likely to result
in a transaction more favorable than that  contemplated by this Agreement to the
shareholders  of PBI  (which  judgment  must be  reasonable),  and (ii) that the
Person making such Takeover Proposal is financially capable of consummating such
Takeover  Proposal or that the financing  necessary to consummate  such Takeover
Proposal,  to the  extent  required,  is then  committed  or is capable of being
obtained by such Person (a "Superior  Proposal").  In addition,  notwithstanding
the provisions of Section 5.13(a) above, in connection with a submitted, written
bona fide Takeover Proposal or potential Takeover Proposal,  PBI shall refer any
third party to this Section  5.13 or make a copy of this Section 5.13  available
to such third party.

               (ii)  In the  event  PBI or any of its  Subsidiaries  receives  a
Superior Proposal, nothing contained in this Agreement (but subject to the terms
of this  Section  5.13(b))  will  prevent  the  Board of  Directors  of PBI from
recommending  such Superior  Proposal to the  shareholders  of PBI, if the Board
determines,  in good faith, after consultation with outside legal counsel,  that
such action is  required by its  fiduciary  duties;  in such case,  the Board of
Directors

                                       35


of PBI may withdraw, modify or refrain from making its recommendations set forth
in the relevant  sections in this Agreement,  and, to the extent it does so, PBI
may  refrain  from  soliciting  proxies  to secure the  affirmative  vote of its
shareholders as contemplated by Section 5.1; provided,  however,  that PBI shall
                                             --------   -------
(A) provide  CBSI at least 48 hours prior  notice of any meeting of the Board of
Directors  of PBI at which such Board of  Directors  is  reasonably  expected to
consider a Superior  Proposal,  (B) not recommend to its shareholders a Superior
Proposal for a period of not less than the greater of two full business days and
48 hours  after  CBSI's  receipt  of a copy of such  Superior  Proposal  and the
identity  of the third  party,  and (C) not enter  into a  definitive  agreement
relating to such Superior  Proposal  unless CBSI fails to match the terms of the
Super  Proposal  within the greater of two full business days and 48 hours after
CBSI's receipt of a copy of such Superior Proposal and the identity of the third
party; and provided,  further, that unless this Agreement is terminated pursuant
to Article VII,  nothing  contained in this  Section  5.13(b)  shall limit PBI's
obligation to hold and convene a special meeting of its shareholders (regardless
of whether the  recommendation  of the Board of Directors of PBI shall have been
withdrawn,  modified or not yet made) or to provide the shareholders of PBI with
material information relating to such meeting.

          (c) Notwithstanding  anything to the contrary herein,  neither PBI nor
any of its  Subsidiaries  shall provide any  non-public  information  to a third
party  unless:  (x) PBI  provides  such  non-public  information  pursuant  to a
nondisclosure  agreement with terms  regarding the protection of oral or written
confidential   information  at  least  as  restrictive  as  such  terms  in  the
confidentiality agreement heretofore entered into by the parties hereto; and (y)
such non-public  information has been previously  delivered or made available to
CBSI.

          (c) There shall not have been  instituted,  pending or  threatened  in
writing any action or proceeding by any governmental authority or administrative
agency or in a court of competent jurisdiction, nor shall there be in any effect
any  judgment,  order,  decree  or  injunction  of any  governmental  authority,

restraint, preventing or seeking to prevent the consummation of the transactions
contemplated by this Agreement.

specifically  relates to an earlier  date, as of such earlier  date),  except as
otherwise  contemplated  by this  Agreement  or  consented to in writing by PBI;
provided,  however,  that  (i)  in  determining  whether  or not  the  condition

     7.1 Termination.  This Agreement may be terminated at any time prior to the
         -----------
Effective Time, either before or after approval by the shareholders of PBI:

          (a) by the mutual  written  consent duly  authorized by the respective
Boards of Directors of the parties hereto;

          (b) by CBSI in writing, if PBI has, or by PBI in writing, if CBSI has,
breached  (i)  any  covenant  or   agreement   contained   herein  or  (ii)  any
representation or warranty  contained  herein,  and in either case if (x) to the
extent  that such breach is  curable,  such breach has not been cured  within 30
days after the date on which  written  notice  thereof is given to the breaching
party,  and (y)  such  breach  would  entitle  the  non-breaching  party  not to
consummate  the  transactions   contemplated  hereby  under  Article  V  hereof;
provided,  however,  that PBI shall not be entitled to terminate  this Agreement
under  this  Section  7.1(b)  for any  breach  or  alleged  breach of any of the
representations  and  warranties of CBSI contained in Sections 4.6 if and to the
extent that CBSI is capable of delivering the aggregate Merger  Consideration at
the  Closing,  and in  Sections  4.3,  4.7 or 4.8 if and to the extent  that any
inaccuracy or breach of any such

                                       38

representation  does not prevent,  or materially hinder or delay, the receipt of
requisite regulatory approvals;

          (c) by any party  hereto in  writing,  if the  applications  for prior
approval  referred to in Section 5.3 hereof have been  finally  denied,  and the
time period for appeals and requests for  reconsideration has expired, or if any
governmental  entity  of  competent  jurisdiction  shall  have  issued  a  final
nonappealable  order  enjoining or otherwise  prohibiting  the Merger,  the Bank
Merger or the Short-Form Merger;

          (d) by any party hereto in writing,  if the shareholders of PBI do not
approve this Agreement and the transactions  contemplated thereby at the special
meetings duly called for that purpose;

          (e) by any party hereto in writing,  if the Merger shall not have been
consummated by the close of business on March 31, 2004, unless the failure to so
consummate  by such date shall be  principally  due to the  failure of the party
seeking to  terminate  this  Agreement to perform or observe the  covenants  and
agreements set forth herein;

          (f) by CBSI,  if (i) the Board of  Directors  of PBI  shall  withdraw,
modify or  change  its  approval  or  recommendation  of this  Agreement  or the
transactions contemplated thereby in a manner adverse to CBSI, or PBI shall have
failed to include in the PBI Proxy Statement the  recommendation of its Board of
Directors  in  favor  of the  approval  of this  Agreement  or the  transactions
contemplated  thereby;  (ii) following its receipt of a Takeover Proposal or the
public announcement of a Takeover Proposal, PBI shall fail to timely comply with
the  covenants  contained  in Section  5.2;  (iii) the Board of Directors of PBI
shall have  recommended to the shareholders of PBI a Superior  Proposal,  or PBI
shall have  executed  a letter of  intent,  a  definitive  agreement  or similar
document  with respect to a Superior  Proposal;  (iv) a tender offer or exchange
offer for 25% or more of the outstanding shares of PBI Common Stock is commenced
and PBI shall not have sent to its  shareholders,  within 10 business days after
the commencement of such tender or exchange offer, a statement that the Board of
Directors of PBI recommends  rejection of such tender or exchange  offer;  (v) a
Takeover  Proposal (other than a tender or exchange offer covered by clause (iv)
of this  Section  7.1(f)) with respect to PBI is publicly  announced  and,  upon
CBSI's request,  PBI fails to issue a press release announcing its opposition to
such Takeover  Proposal  within three (3) business  days after such request;  or
(vi) the  Board of  Directors  of PBI shall  have  resolved  to take any  action
described in clauses (i) and (iii) of this Section 7.1(f); or

          (g) by PBI, if the Board of Directors of PBI shall have recommended to
the shareholders of PBI a Superior Proposal, or PBI shall have executed a letter
of intent, a definitive agreement or similar document with respect to a Superior
Proposal,  in each case in accordance  with Section 5.12,  provided that PBI has
complied with all provisions thereof.

     7.2  Effect of  Termination.  In the event  this  Agreement  is  terminated
          ----------------------
pursuant to Section 7.1 hereof,  this  Agreement  shall  become void and have no
effect,  except that (i) the provisions  relating to  confidentiality,  break-up
fees and expenses set forth in Sections 5.5 and 7.3 hereof, respectively,  shall
survive  any such  termination  and (ii) a  termination  pursuant to Section

                                       39


7.1 shall not relieve the breaching  party from liability for any willful breach
of such covenant or agreement or  representation or warranty giving rise to such
termination.

     7.3 Fees and Expenses.
         -----------------

          (a) Except as set forth in this  Section  7.3,  all fees and  expenses
incurred in connection  with this  Agreement and the  transactions  contemplated
hereby shall be paid by the party  incurring such expenses,  whether or not such
transactions are consummated.

          (b) In the  event  that  this  Agreement  is  terminated  (i) by  CBSI
pursuant to Section 7.1(b) (but only in the event of a willful or knowing breach
of a  representation,  warranty  or covenant  of PBI) or Section  7.1(f),  or by
either party pursuant to Section 7.1(d) or (e) after a Takeover  Proposal from a
third party is received by PBI or made public (unless CBSI or Merger Sub is then
in breach of its  representations,  warranties  or  covenants  contained in this
Agreement  such that  conditions set forth in Section 6.2(a) or (b) would not be
satisfied,  and PBI shall have given written notice to that effect prior to such
termination),  or (ii) by PBI pursuant to Section 7.1(g),  then PBI shall pay in
immediately  available  funds to an account  designated  by CBSI,  no later than
three (3) business days after the date of such  termination,  all  out-of-pocket
costs and expenses  (including  limitation,  professional fees of legal counsel,
financial  advisors and accountants,  and their expenses)  actually  incurred by
CBSI and its Subsidiaries in connection with the Merger, the Bank Merger and the
Short-Form  Merger,  and this  Agreement,  such costs and expenses not to exceed
$35,000 in the aggregate.  In addition, in such event, if (x) PBI or OFSLA shall
have  consummated  a  transaction  with a third party with respect to a Takeover
Proposal  within one year of the  termination of this  Agreement,  or (y) within
such one-year  period,  any third party Person  consummates a tender or exchange
offer for 25% or more of the outstanding PBI Common Stock, then PBI shall pay in
immediately  available  funds to an account  designated  by CBSI,  no later than
three (3) business days after the date of the applicable triggering event, a fee
equal to ONE HUNDRED SIXTY THOUSAND DOLLARS  ($160,000),  as liquidated  damages
and not as a penalty.

     7.4   Survival  of   Representations,   Warranties   and   Covenants.   All
           --------------------------------------------------------------
representations, warranties and covenants in this Agreement or in any instrument
delivered  pursuant  hereto shall expire on, and be terminated and  extinguished
at, the Effective  Time other than  covenants that by their terms are to survive
or  be   performed   after  the   Effective   Time;   provided,   that  no  such
representations,  warranties  or covenants  shall be deemed to be  terminated or
extinguished so as to deprive CBSI, Merger Sub or PBI (or any director,  officer
or controlling  Person  thereof) of any defense in law or equity which otherwise
would  be  available  against  the  claims  of any  Person,  including,  without
limitation,  any  shareholder  or former  shareholder of either CBSI or PBI, the
aforesaid  representations,  warranties and covenants being material inducements
to the consummation by CBSI, Merger Sub and PBI of the transactions contemplated
herein.

     7.5 Waiver.  Except where not permitted by law, CBSI, Merger Sub or PBI, by
         ------
written instrument signed by an executive officer of such party, may at any time
(whether before or after approval of this Agreement by the  shareholders of PBI)
extend the time for the  performance of any of the  obligations or other acts of
the other party,  and may waive (i) any  inaccuracies of such other party in the
representations  or  warranties  contained  in this  Agreement

                                       40


or any document  delivered  pursuant  hereto,  (ii)  compliance  with any of the
covenants,  undertakings  or agreements of such other party,  or satisfaction of
any of the conditions  precedent to its  obligations,  contained herein or (iii)
the  performance by such other party of any of its obligations set out herein or
therein.  No failure or delay on the part of any party hereto in the exercise of
any right  hereunder  shall impair such right or be construed as a waiver of, or
acquiescence in, any breach of any representation, warranty or agreement herein,
nor shall any single or partial  exercise  of any such right  preclude  other or
further exercise thereof or of any other right.

     7.6 Amendment or Supplement.  This Agreement may be amended or supplemented
         -----------------------
at any time prior to the Effective Time only by mutual  agreement of the parties
hereto or  thereto.  Any such  amendment  or  supplement  must be in writing and
approved by their respective Boards of Directors; provided, however, that, after
                                                  --------  -------
approval of this Agreement by the respective  shareholders  of PBI, no amendment
may be made which by law requires further approval by such shareholders  without
obtaining such further approval.

not be  unreasonably  withheld,  elect,  subject to the filing of all  necessary
applications and the receipt of all required regulatory approvals, to modify the

consideration  to be paid to the holders of the PBI Common  Stock is not thereby
changed in kind or reduced in amount as a result of such modification, (ii) such
modification  will not materially  delay or jeopardize the  consummation  of the
transactions  contemplated  by the  Agreement,  and (iii) any such  modification
