("Agreement"), among Parkvale Financial Corporation ("Parkvale"), a Pennsylvania
corporation,  Parkvale  Savings  Bank (the  "Bank"),  a  Pennsylvania  chartered
savings  bank and a  wholly-owned  subsidiary  of  Parkvale,  Advance  Financial
Bancorp ("Advance"), a Delaware corporation,  and Advance Financial Savings Bank
("Advance  Savings"),  a  federally-chartered   savings  bank  and  wholly-owned

                                   WITNESSETH:

         WHEREAS,  the Boards of Directors of  Parkvale,  the Bank,  Advance and
Advance  Savings  have  determined  that it is in the  best  interests  of their
respective   companies  and  their   stockholders  to  consummate  the  business
combination transactions provided for herein; and

         WHEREAS,  the  parties  desire to  provide  for  certain  undertakings,
conditions,  representations,  warranties  and covenants in connection  with the
transactions contemplated hereby; and

         WHEREAS,  as a condition and inducement to the  willingness of Parkvale
to enter into this  Agreement,  the directors and executive  officers of Advance
(the  "Advance  Stockholders")  are  concurrently  entering  into a  Stockholder
Agreement with Parkvale (the "Stockholder Agreement"), in substantially the form
attached  hereto as Exhibit A,  pursuant  to which,  among  other  things,  such
directors  agree to vote their shares of Advance Common Stock (as defined below)
in favor of this Agreement and the transactions contemplated hereby.

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
covenants,  representations,  warranties and agreements  herein  contained,  the
parties hereto agree as follows:

                                    ARTICLE I

                                   THE MERGER

         1.01 The Merger.  Subject to the terms and conditions of this Agreement
and subject to and in accordance with an Agreement of Merger, a copy of which is
attached  hereto as Exhibit B (the  "Agreement of Merger"),  between Advance and
Advance Acquisition Corp. ("Interim"),  a Delaware corporation to be formed as a
wholly-owned   subsidiary  of  Parkvale  in  connection  with  the  transactions
contemplated  hereby, at the Effective Time (as defined in Section 1.05 hereof),
Interim shall be merged with and into Advance in accordance  with Section 251 of
the Delaware  General  Corporation Law ("DGCL") (the "Merger"),  with Advance as
the  surviving   corporation   (hereinafter   sometimes  called  the  "Surviving
Corporation").  Simultaneously with or immediately following consummation of the
Merger, the parties hereto will cause Advance Savings to be merged with and into
the  Bank,  with the Bank as the  resulting  institution  (the  "Bank  Merger").
Simultaneously with



or as soon as practicable after the Bank Merger, the Surviving Corporation shall
be merged with and liquidated  into Parkvale (the  "Liquidation")  in accordance
with an Agreement and Plan of Liquidation,  the form of which is attached hereto
as Exhibit C.

         1.02  Effect of the  Merger.  As of the  Effective  Time (as defined in
Section 1.05 hereof),  the Surviving  Corporation  shall be considered  the same
business and  corporate  entity as each of Advance and Interim and thereupon and
thereafter,  all the property,  rights, powers and franchises of each of Advance
and  Interim  shall  vest  in  the  Surviving   Corporation  and  the  Surviving
Corporation  shall be subject to and be deemed to have assumed all of the debts,
liabilities,  obligations  and duties of each of Advance  and  Interim and shall
have succeeded to all of each of their relationships, fiduciary or otherwise, as
fully and to the same extent as if such  property  rights,  privileges,  powers,
franchises,  debts,  obligations,  duties and  relationships had been originally
acquired,  incurred or entered into by the Surviving  Corporation.  In addition,
any  reference  to either of Advance or Interim  in any  contract  or  document,
whether  executed or taking effect before or after the Effective Time,  shall be
considered a reference to the Surviving Corporation if not inconsistent with the
other  provisions of the contract or document;  and any pending  action or other
judicial  proceeding to which either of Advance or Interim is a party, shall not
be deemed to have abated or to have  discontinued  by reason of the Merger,  but
may be  prosecuted to final  judgment,  order or decree in the same manner as if
the Merger had not been made; or the Surviving Corporation may be substituted as
a party to such action or proceeding,  and any judgment,  order or decree may be
rendered for or against it that might have been  rendered for or against  either
of Advance or Interim if the Merger had not occurred. At the Effective Time, the
directors  and  officers  of the  Surviving  Corporation  shall  be the  persons
designated in Section 1.04.

         1.03 Certificate of Incorporation and Bylaws. As of the Effective Time,
the Certificate of Incorporation  and Bylaws of Advance shall be the Certificate
of Incorporation and Bylaws of the Surviving Corporation until otherwise amended
as provided by law.

         1.04  Directors and Officers.  As of the Effective  Time, the directors
and officers of Interim shall become the directors and officers of the Surviving
Corporation.  The directors of Advance and/or Advance Savings shall resign as of
the Effective Time.

         1.05  Effective  Time.  The  Merger  shall  become  effective  upon the
occurrence of the filing of a Certificate  of Merger with the Secretary of State
of the State of Delaware  pursuant  to Section  251 of the DGCL,  unless a later
date and time is specified as the effective  time in such  Certificate of Merger
("Effective Time"). A closing (the "Closing") shall take place immediately prior
to the  Effective  Time at 10:00 a.m.,  on the fifth  business day following the
receipt of all necessary  regulatory or governmental  approvals and consents and
the  expiration  of all  statutory  waiting  periods in respect  thereof and the
satisfaction or waiver, to the extent permitted hereunder,  of the conditions to
the  consummation of the Merger  specified in Article V of this Agreement (other
than the delivery of  certificates  and other  instruments  and  documents to be
delivered at the Closing), at the offices of Parkvale or at such other place, at
such other time, or on such other date as the parties may mutually

                                        2



agree upon.  At the Closing,  there shall be  delivered  to Parkvale,  the Bank,
Advance and Advance Savings the certificates and other documents  required to be
delivered under Article V hereof.

         1.06 Modification of Structure.  Notwithstanding  any provision of this
Agreement to the contrary,  Parkvale, with the prior written consent of Advance,
which  consent shall not be  unreasonably  withheld,  may elect,  subject to the
filing of all necessary  applications and the receipt of all required regulatory
approvals,  to modify the structure of the transactions  contemplated  hereby so
long  as (i)  there  are no  adverse  federal  income  tax  consequences  to the
stockholders  of  Advance  as a result  of such  modification,  (ii) the  Merger
Consideration  (as defined  below) to be paid to holders of Advance Common Stock
(as  defined  below)  under this  Agreement  is not  thereby  changed in kind or
reduced  in  amount  solely  because  of  such   modification   and  (iii)  such
modification will not be likely to materially delay or jeopardize receipt of any
required  regulatory  approvals  or impair or prevent  the  satisfaction  of any
conditions to the Closing.

         1.07  Conversion  of  Advance  Common  Stock  and  Options.  As of  the
Effective  Time,  each share of common stock,  par value  $0.0667 per share,  of
Advance (the  "Advance  Common  Stock," which shall include the rights issued by
Advance  pursuant  to the Rights  Agreement  dated July 17,  1997,  as  amended,
between  Advance and  American  Securities  Transfer & Trust,  Incorporated,  as
Rights Agent, relating to Advance's Junior Participating Preferred Stock, Series
A, par value  $.10 per share  (the  "Advance  Rights  Agreement")),  issued  and
outstanding immediately prior to the Effective Time (other than shares (i) as to
which  dissenters'  rights have been  asserted and duly  perfected in accordance
with the DGCL  ("Dissenting  Shares"),  (ii) under the Advance  Restricted Stock
Plan ("RSP") which have not been allocated, and (iii) held by Advance (including
treasury  shares) or Parkvale  or the Bank other than in a  fiduciary  capacity,
which shares shall be cancelled)  shall, by virtue of the Merger and without any
action on the part of the holder  thereof,  be cancelled and by operation of law
be converted  into and represent the right to receive from  Parkvale,  $26.00 in
cash (the "Merger  Consideration") in accordance with Section 1.08 hereof. At or
immediately  prior to the Effective  Time, each  outstanding  option to purchase
Advance  Common Stock  issued by Advance and as described on Advance  Disclosure
Schedule 2.02  ("Advance  Option"),  shall be cancelled,  and each holder of any
such  Advance  Option,  whether  or not then  vested  or  exercisable,  shall be
entitled to receive from Advance  immediately  prior to the  Effective  Time for
each Advance Option an amount  determined by  multiplying  (i) the excess of the
Merger  Consideration  over the  applicable  exercise  price  per  share of such
Advance  Option by (ii) the number of shares of Advance  Common Stock subject to
such  Advance  Option  ("Option  Consideration").  The  payment  of  the  Option
Consideration  referred to in the immediately  preceding  sentence to holders of
Advance  Options  shall be subject to the  execution  by any such holder of such
instruments  of  cancellation  as  Advance  and  Parkvale  may  reasonably  deem
appropriate.  Advance  may make  necessary  tax  withholdings  from  the  Option
Consideration as it deems  appropriate.  The aggregate  consideration to be paid
for the  conversion  of all  outstanding  shares  of  Advance  Common  Stock  is
hereinafter referred to as the "Aggregate Merger Consideration."

                                        3



         1.08     Exchange Procedures

         (a) Immediately prior to the Effective Time,  Parkvale shall deposit in
trust with an exchange agent designated by Parkvale and reasonably acceptable to
Advance (the "Exchange  Agent") cash in an amount equal to the Aggregate  Merger
Consideration.  No later than five business days  following the Effective  Time,
Parkvale  shall cause the  Exchange  Agent to mail to each holder of record of a
certificate  or  certificates  which  immediately  prior to the  Effective  Time
represented  issued and outstanding  shares of Advance Common Stock a notice and
letter of  transmittal  (which shall specify that delivery shall be effected and
risk of loss and title to the certificates  theretofore  representing  shares of
Advance Common Stock shall pass only upon proper  delivery of such  certificates
to the Exchange Agent) advising such holder of the  effectiveness  of the Merger
and the procedure for  surrendering  to the Exchange  Agent such  certificate or
certificates  which immediately  prior to the Effective Time represented  issued
and outstanding shares of Advance Common Stock in exchange for the consideration
set forth in Section 1.07 hereof deliverable in respect thereof pursuant to this
Agreement.   Within  five  business  days   following   receipt  of  surrendered
certificates and a properly completed letter of transmittal,  the Exchange Agent
shall deliver the Merger  Consideration  to which such former holder is entitled
to each  former  Advance  stockholder.  The  Exchange  Agent  shall  accept such
certificates  upon compliance  with such reasonable  terms and conditions as the
Exchange Agent  reasonably may impose to effect an orderly  exchange  thereof in
accordance with normal exchange practices.

         (b) Each  outstanding  certificate  which prior to the  Effective  Time
represented Advance Common Stock (other than Dissenting Shares) and which is not
surrendered to the Exchange Agent in accordance with the procedures provided for
herein shall, except as otherwise herein provided, until duly surrendered to the
Exchange  Agent,  be  deemed  to  evidence  the  right  to  receive  the  Merger
Consideration.  After the Effective Time,  there shall be no further transfer on
the records of Advance of  certificates  representing  shares of Advance  Common
Stock and if such certificates are presented to Advance for transfer, they shall
be  cancelled  against  delivery  of the  Merger  Consideration  as  hereinabove
provided.

         (c) Parkvale shall not be obligated to deliver the Merger Consideration
to which a holder of Advance  Common  Stock  would  otherwise  be  entitled as a
result  of  the  Merger  until  such  holder   surrenders  the   certificate  or
certificates  representing  the shares of Advance  Common  Stock for exchange as
provided in this Section 1.08, or, in lieu thereof, an appropriate  affidavit of
loss and  indemnity  agreement  and/or a bond as may be required in each case by
Parkvale.  If payment of the Merger  Consideration is to be made in a name other
than that in which the certificate  evidencing  Advance Common Stock surrendered
in exchange  therefor is  registered,  it shall be a condition  of the  issuance
thereof  that the  certificate  so  surrendered  shall be  properly  endorsed or
accompanied by an executed form of assignment  separate from the certificate and
otherwise  in proper  form for  transfer  and that the  person  requesting  such
payment pay to the Exchange Agent in advance, any transfer or other tax required
by reason of the payment in any name other than that of the registered holder of
the certificate  surrendered or otherwise  establish to the  satisfaction of the
Exchange Agent that such tax has been paid or is not payable.

                                        4



         (d) Any portion of the Aggregate Merger Consideration  delivered to the
Exchange  Agent by Parkvale  pursuant to Section 1.07 that remains  unclaimed by
the  stockholders of Advance for six months after the Effective Time (as well as
any proceeds  from any  investment  thereof)  shall be delivered by the Exchange
Agent to Parkvale.  Any  stockholders  of Advance who have not  exchanged  their
shares of Advance Common Stock for the Merger  Consideration  in accordance with
this  Agreement  shall  thereafter  look only to Parkvale for the  consideration
deliverable  in respect of each share of Advance  Common Stock such  stockholder
holds as determined  pursuant to this Agreement without any interest thereon. If
outstanding  certificates for shares of Advance Common Stock are not surrendered
or the payment for them is not claimed prior to the date on which payment of the
Merger  Consideration  would otherwise  escheat to or become the property of any
governmental unit or agency,  the unclaimed items shall, to the extent permitted
by  abandoned  property  and any other  applicable  law,  become the property of
Parkvale  (and to the extent not in its  possession  shall be  delivered to it),
free and clear of all claims or  interest of any person  previously  entitled to
such property.  Neither the Exchange Agent nor any party to this Agreement shall
be  liable  to any  holder  of  stock  represented  by any  certificate  for any
consideration  paid  to a  public  official  pursuant  to  applicable  abandoned
property,  escheat or similar  laws.  Parkvale and the  Exchange  Agent shall be
entitled  to rely upon the stock  transfer  books of  Advance to  establish  the
identity of those persons entitled to receive the Merger Consideration specified
in this Agreement,  which books shall be conclusive with respect thereto. In the
event of a  dispute  with  respect  to  ownership  of stock  represented  by any
certificate,  Parkvale and the  Exchange  Agent shall be entitled to deposit any
consideration  represented thereby in escrow with an independent third party and
thereafter be relieved with respect to any claims thereto.

         1.09  Withholding  Rights.  Parkvale  (through the Exchange  Agent,  if
applicable)  shall be entitled to deduct and withhold from any amounts otherwise
payable  pursuant to this  Agreement  to any holder of shares of Advance  Common
Stock such amounts as Parkvale is required  under the  Internal  Revenue Code of
1986, as amended ("Code"),  or any provision of state,  local or foreign tax law
to deduct and withhold with respect to the making of such  payment.  Any amounts
so withheld shall be withheld in accordance  with the Code and other  applicable
laws and  regulations and shall be treated for all purposes of this Agreement as
having been paid to the holder of Advance  Common Stock in respect of which such
deduction and withholding was made by Parkvale.

         1.10 Dissenting Shares.  Each outstanding share of Advance Common Stock
the holder of which has  perfected  his right to dissent  under the DGCL and has
not effectively withdrawn or lost such rights as of the Effective Time shall not
be converted into or represent a right to receive the Merger Consideration,  and
the holder  thereof  shall be entitled only to such rights as are granted by the
DGCL.  Advance shall give Parkvale  prompt notice upon receipt by Advance of any
such  written  demands for payment of their fair value of such shares of Advance
Common  Stock and of  withdrawals  of such  demands  and any  other  instruments
provided  pursuant to the DGCL (any  stockholder  duly making such demand  being
hereinafter called a "Dissenting Stockholder").  Any payments made in respect of
Dissenting Shares shall be made by Parkvale. If any Dissenting Stockholder shall
effectively withdraw or lose (through failure to perfect or otherwise) his right
to such payment at or prior to the Effective  Time, each such holder's shares of
Advance Common

                                        5


Stock shall be  converted  into a right to receive the Merger  Consideration  in
accordance with the applicable provisions of this Agreement.

         1.11  Additional  Actions.  If at any time after the Effective Time the
Surviving  Corporation shall consider that any further assignments or assurances
in law or any other acts are  necessary  or  desirable  to (i) vest,  perfect or
confirm, of record or otherwise,  in the Surviving Corporation its rights, title
or interest in, to or under any of the rights,  properties  or assets of Advance
acquired or to be acquired by the  Surviving  Corporation  as a result of, or in
connection  with, the Merger,  or (ii) otherwise  carry out the purposes of this
Agreement, Advance and its proper officers and directors shall be deemed to have
granted to the Surviving Corporation an irrevocable power of attorney to execute
and deliver all such proper deeds,  assignments  and assurances in law and to do
all acts necessary or proper to vest, perfect or confirm title to and possession
of such rights,  properties or assets in the Surviving Corporation and otherwise
to carry  out the  purposes  of this  Agreement;  and the  proper  officers  and
directors  of the  Surviving  Corporation  are fully  authorized  in the name of
Advance or otherwise to take any and all such action.

         1.12 Interim Shares. Each outstanding share of common stock of Interim,
$.01 par value per share ("Interim  Common Stock"),  on the Effective Time shall
be  converted  automatically  and  without  any action on the part of the holder
thereof into an equal number of shares of the Surviving Corporation, which shall
constitute all of the outstanding common stock of the Surviving Corporation.

                    REPRESENTATIONS AND WARRANTIES OF ADVANCE
                               AND ADVANCE SAVINGS

         References  to  "Advance  Disclosure  Schedules"  shall mean all of the
disclosure schedules required by this Article II and Article IV hereof, dated as
of the date hereof and  referenced to the specific  sections and  subsections of
this  Agreement,  which have been delivered by Advance to Parkvale.  Advance and
Advance Savings hereby represent and warrant to Parkvale and the Bank as follows
as of the date hereof:

         2.01     Corporate Organization.

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

                                        6



Advance is  registered  as a savings  and loan  holding  company  under the Home
Owners' Loan Act ("HOLA").  Advance Disclosure  Schedule 2.01(a) sets forth true
and complete copies of the Certificate of Incorporation and Bylaws of Advance as
in effect on the date hereof.

         For purposes of this  Agreement,  the term "Material  Adverse  Effect",
when  applied  to a party,  shall mean any event,  change or  occurrence  which,
together  with any other event,  change or  occurrence,  has a material  adverse
impact  on (i)  the  financial  position,  business,  results  of  operation  or
financial performance of such party and their respective subsidiaries,  taken as
a whole, or (ii) the ability of such party to perform its obligations under this
Agreement or to consummate the Merger and the other transactions contemplated by
this Agreement in a timely fashion; provided,  however, that a "Material Adverse
Effect" shall not be deemed to include the impact of (a) actions or omissions of
a party taken with the prior written  consent of the other in  contemplation  of
the  transactions  contemplated  by this  Agreement,  (b) changes in banking and
similar laws or regulations of general applicability or interpretations  thereof
by courts  or  governmental  authorities,  (c)  changes  in  generally  accepted
accounting principles or regulatory accounting requirements applicable to banks,
savings associations and bank or thrift holding companies generally, (d) changes
attributable  to or  resulting  from  changes  in general  economic  conditions,
including  changes in the prevailing  level of interest rates, or (e) the Merger
and related  expenses  associated  with the  transactions  contemplated  by this
Agreement.

         (b) The only  direct or  indirect  subsidiaries  of Advance are Advance
Savings,  Advance  Financial  Service  Corporation  of West Virginia and Advance
Statutory Trust I (together,  the "Advance  Subsidiaries").  Advance  Disclosure
Schedule  2.01(b)(i)  sets  forth  true  and  complete  copies  of the  Charter,
Certificate of Incorporation, Bylaws or other governing documents of each of the
Advance  Subsidiaries  as in  effect  on the date  hereof.  Each of the  Advance
Subsidiaries (i) is duly organized,  validly existing and in good standing under
the laws of its respective jurisdiction of incorporation or formation,  (ii) has
the corporate or trust power and authority to own or lease all of its properties
and assets,  and (iii) is duly  licensed or  qualified  to do business and is in
good standing in each jurisdiction in which the nature of the business conducted
by it or the character or location of the  properties and assets owned or leased
by it makes such licensing or qualification necessary,  except where the failure
to be so  licensed,  qualified  or in good  standing  would not have a  Material
Adverse  Effect.  Advance and Advance  Savings  have  satisfied  in all material
respects all commitments,  financial or otherwise,  as may have been agreed upon
with their state  and/or  federal  regulatory  agencies.  Other than the Advance
Subsidiaries and except as set forth in Advance Disclosure Schedule 2.01(b)(ii),
Advance  does not own or control,  directly  or  indirectly,  greater  than a 5%
equity interest in any corporation,  company,  association,  partnership,  joint
venture or other entity. In addition,  Advance Disclosure  Schedule  2.01(b)(ii)
lists  the  primary   activities   engaged  in  by  Advance   Financial  Service
Corporation.

         2.02  Capitalization.  The authorized capital stock of Advance consists
of 2,000,000  shares of Advance Common Stock,  of which 1,398,373 are issued and
outstanding  as of the date hereof,  and 500,000 shares of preferred  stock,  of
which no shares are  issued and  outstanding.  The  1,398,373  shares of Advance
Common Stock issued and outstanding as of the date hereof include 2,931

shares of capital  stock of Advance,  and all issued and  outstanding  shares of
capital stock of each of the Advance Subsidiaries, have been duly authorized and
validly issued and are fully paid,  nonassessable and free of preemptive rights.
All of  the  outstanding  shares  of  capital  stock  of  each  of  the  Advance
Subsidiaries  are owned  directly or indirectly by Advance free and clear of any
liens,  encumbrances,  charges,  restrictions  or rights of third parties of any
kind  whatsoever,  and, except for (i) an aggregate of 155,859 shares of Advance
Common Stock issuable upon exercise of stock options ("Advance Options") granted
pursuant to Advance's  1998 Stock Option Plan (the "Stock Option Plan") and (ii)

warrants,  calls,  commitments  or agreements  of any character  calling for the
transfer,  purchase or issuance of any shares of capital stock of Advance or any
of the Advance Subsidiaries or any securities representing the right to purchase

stock. Advance Disclosure Schedule 2.02 lists each Advance Option outstanding as

the transactions contemplated hereby and thereby by the stockholders of Advance,
and the receipt of all  required  regulatory  approvals  and  expiration  of any
related waiting periods, Advance has full corporate power

                                        8

reorganization,  moratorium or other similar laws  affecting  creditors'  rights
generally,  and except that the availability of equitable  remedies  (including,

appropriate court.

Advance  Savings,  the  execution  and  delivery of the  Agreement  of Merger by
Advance,  the  consummation by Advance and Advance  Savings of the  transactions
contemplated  hereby in accordance  with the terms hereof,  the  consummation by
Advance  of  the  transactions  contemplated  by  the  Agreement  of  Merger  in
accordance  with the terms  thereof,  compliance by Advance and Advance  Savings

this Agreement and the Agreement of Merger and  consummation of the transactions
contemplated  herein and therein,  including without limitation  consummation of
the  Merger  pursuant  to this  Agreement,  shall not result in the grant of any

accompanied  by the audit report of S.R.  Snodgrass,  A.C.,  independent  public
accountants.  The consolidated  balance sheets of Advance referred to herein, as
well as the financial statements to be delivered pursuant to Section 4.04 hereof

financial condition of Advance as of the respective dates set forth therein, and
the related consolidated  statements of income,  changes in stockholders' equity
and cash flows (including the related notes, where  applicable),  fairly present
or will  fairly  present,  as the case may be, the  results of the  consolidated
income,  changes in  stockholders'  equity  and cash  flows of  Advance  for the
respective  periods or as of the  respective  dates set forth  therein (it being
understood that Advance's interim  financial  statements are not audited and are
not  prepared  with  all  related  notes  and are  subject  to  normal  year end
adjustments  but  have  been,  or will  be,  prepared  in  compliance  with  all
applicable  legal  and  regulatory  accounting   requirements  and  reflect  all
adjustments  which  are,  in  the  opinion  of  Advance,  necessary  for a  fair
presentation of such financial statements).

         (b) Each of the financial  statements  referred to in this Section 2.04
(including the related notes,  where applicable) has been prepared in accordance
with generally accepted accounting  principles  consistently  applied during the
periods  involved.  The books and  records  of Advance  and each of the  Advance
Subsidiaries are being  maintained in material  compliance with applicable legal
and accounting requirements and reflect only actual transactions.

         (c) Except to the extent  reflected,  disclosed or reserved  against in
the  consolidated  financial  statements  referred  to in the first  sentence of
Section 2.04(a) or the notes thereto,  and except for liabilities incurred since
June 30,  2004 in the  ordinary  course of  business  and  consistent  with past
practice,  neither  Advance nor any Advance  Subsidiary  has any  obligation  or
liability,  whether absolute, accrued, contingent or otherwise,  material to the

there are no pending or, to the best  knowledge of Advance and Advance  Savings,
threatened  legal,  administrative,  arbitration or other  proceedings,  claims,
actions or  governmental  investigations  of any nature  against  Advance or any
Advance  Subsidiary,  except such proceedings,  claims,  actions or governmental
investigations  which in the good faith judgment of Advance and Advance  Savings

Subsidiary  is a party to any  order,  judgment  or  decree  which  has or could
reasonably be expected to have a Material Adverse Effect.

         2.07     Taxes and Tax Returns.

         (a)  Advance  and each of the Advance  Subsidiaries  has  (taking  into
account any extension of time within which to file which has not expired) timely

case of both (i) and (ii) no  deficiencies  were  asserted  as a result  of such
examinations  which have not been resolved and paid in full. There are no audits
or other  administrative  or court  proceedings  presently pending nor any other
disputes  pending,  or claims asserted for, Taxes or assessments upon Advance or

Subsidiaries  given any currently  outstanding  waivers or  comparable  consents
regarding  the  application  of the statute of  limitations  with respect to any
Taxes or Returns.

                                       11



         (b) Except as set forth in Advance Disclosure Schedule 2.07(b), neither

Advance or any Advance  Subsidiary (nor does Advance have any knowledge that the
IRS has proposed any such  adjustment or change of accounting  method),  or (iv)

Section 341(f)(2) of the Code apply.

or additional amounts imposed by any taxing authority (domestic or foreign) upon
Advance or any Advance Subsidiary.

         2.08     Employee Benefit Plans.

         (a) Each employee  benefit plan or arrangement of Advance or any of the
Advance  Subsidiaries  which is an "employee benefit plan" within the meaning of
Section 3(3) of the Employee  Retirement Income Security Act of 1974, as amended
("ERISA"),  is listed in Advance Disclosure  Schedule 2.08(a) ("Advance Plans").

actuarial and financial  reports prepared with respect to any qualified  Advance
Plans,  (ii) the most recent annual reports filed with any government agency for
any qualified or  non-qualified  plan,  and (iii) all rulings and  determination

         (b) Each of the Advance  Plans has been  operated in  compliance in all
material  respects  with the  applicable  provisions  of ERISA,  the  Code,  all

other applicable governmental laws and regulations.

         (c) Neither Advance nor any of the Advance Subsidiaries participates in
or has  incurred  any  liability  under  Section 4201 of ERISA for a complete or
partial  withdrawal  from a multi-  employer  plan (as such term is  defined  in

                                       12



         (d) Except as set forth in Advance  Disclosure  Schedule  2.08(d),  the
present value of all accrued liabilities under each of the Advance Plans subject
to Title IV of ERISA  did not,  as of the  latest  valuation  date of each  such
Advance  Plan,  exceed the fair market  value of the assets of such Advance Plan
allocable to such accrued  liabilities,  based upon the actuarial and accounting
assumptions  currently  utilized  for  such  Advance  Plans  (as of  the  latest
valuation date).

         (e) Neither  Advance nor any of the Advance  Subsidiaries,  nor, to the
best  knowledge  of Advance and  Advance  Savings,  any  trustee,  fiduciary  or
administrator of an Advance Plan or any trust created thereunder, has engaged in
a "prohibited transaction," as such term is defined in Section 4975 of the Code,
which could subject Advance or any of the Advance Subsidiaries,  or, to the best
knowledge  of  Advance  and  Advance   Savings,   any   trustee,   fiduciary  or
administrator thereof, to the tax or penalty on prohibited  transactions imposed
by Section 4975.

         (f)  No  Advance  Plan  or  any  trust  created   thereunder  has  been
terminated,  nor have there been any  "reportable  events"  with  respect to any
Advance  Plan  subject to Title IV of ERISA,  as that term is defined in Section
4043(b) of ERISA.

         (g) No Advance Plan or any trust  created  thereunder  has incurred any

under  Section  401(a) of the Code  received a  favorable  determination  letter
issued by the IRS to the effect that such plan is qualified under Section 401(a)
of the Code and the trust  associated with such plan is tax exempt under Section
501 of the Code,  and  Advance  is not aware of any fact or  circumstance  which
would adversely affect the qualified status of any such plan.

         (i)  Neither  Advance  nor  any of the  Advance  Subsidiaries  has  any
obligations  for retiree  health and life benefits under any Advance Plans other
than as may be required  under Section 4980B of the Code or Part 6 of Title I of
ERISA, or under the continuation of coverage provisions of the laws of any state
or locality.  Advance or Advance Savings may amend or terminate any such Advance
Plan at any time without incurring any liability thereunder.

         (j) Except as set forth on Advance Disclosure Schedule 2.08(j), none of
the  execution  of this  Agreement,  stockholder  approval of this  Agreement or
consummation  of the  transactions  contemplated  hereby  will (A)  entitle  any
employees of Advance or any Advance  Subsidiary to severance pay or any increase
in severance pay upon any termination of employment  after the date hereof,  (B)
accelerate  the time of payment or  vesting  or trigger  any  payment or funding
(through a grantor  trust or  otherwise)  of  compensation  or  benefits  under,
increase the amount  payable or trigger any other material  obligation  pursuant
to, any of the Advance  Plans,  (C) result in any breach or  violation  of, or a
default under,  any of the Advance Plans or (D) result in any payment that would
be a  "parachute  payment"  to a  "disqualified  individual"  as those terms are
defined in Section 280G of the Code,  without  regard to whether such payment is
reasonable  compensation for personal  services  performed or to be performed in
the future.

such final  registration  statement,  prospectus,  annual,  quarterly or current
report and definitive  proxy statement or other  communication,  as of its date,
complied  in all  material  respects  with all  applicable  statutes,  rules and
regulations and did not contain any untrue  statement of a material fact or omit
to state any material fact  required to be stated  therein or necessary in order
to make the statements made therein,  in light of the circumstances  under which
they were made,  not  misleading;  provided that  information as of a later date
shall be deemed to modify information as of an earlier date.

         (b) Since January 1, 2001, Advance and each of the Advance Subsidiaries
has duly filed with the OTS, in materially  correct form the monthly,  quarterly

filings,  applications and registrations with, federal, state, local and foreign
governmental  or regulatory  bodies that are required in order to permit them to
carry on their  respective  businesses as they are presently being conducted and
the absence of which  could  reasonably  be expected to have a Material  Adverse
Effect;  all such  permits,  licenses,  certificates  of  authority,  orders and
approvals are in full force and effect; and to the best knowledge of Advance and
the Advance  Subsidiaries,  no suspension or  cancellation of any of the same is
threatened.

         (b) Neither Advance nor any of the Advance Subsidiaries is in violation
of  its  Certificate  of  Incorporation,  Charter,  Bylaws  or  other  governing

order,  rule or regulation of any federal,  state,  local or other  governmental

municipal securities,  safety, health, zoning,  anti-discrimination,  antitrust,
and wage and hour  laws,  ordinances,  orders,  rules  and  regulations),  or in
default with respect to any order, writ, injunction or decree of

governmental  agency,  any of which  violations or defaults could  reasonably be
expected to have a Material Adverse Effect,  and neither Advance nor any Advance
Subsidiary has received any notice or communication  from any federal,  state or
local governmental authority asserting that Advance or any Advance Subsidiary is
in  violation  of any of the  foregoing  which  violation  could  reasonably  be
expected  to have a Material  Adverse  Effect.  Neither  Advance nor any Advance
Subsidiary is subject to any regulatory or  supervisory  cease and desist order,
agreement, written directive,  memorandum of understanding or written commitment
(other than those of general  applicability  to all commercial  banks or savings
associations  issued by  governmental  authorities),  and  neither  of them have
received  any  written  communication  requesting  that it enter into any of the
foregoing.

         2.11     Deposit Insurance and Other Regulatory Matters.

         (a) The deposit  accounts of Advance Savings are insured by the Savings

consummation  of the  transactions  contemplated  hereby.  Furthermore,  Advance

the Agreement of Merger or upon or following consummation of the

                                       15



transactions  contemplated  by this Agreement or the Agreement of Merger (either
alone or in connection  with the occurrence of any  additional  acts or events),
(v) any agreement,  arrangement or  understanding to which Advance or any of the
Advance  Subsidiaries  is a party  or by which  any of the  same is bound  which
limits the freedom of Advance or any of the Advance  Subsidiaries  to compete in
any line of  business or with any person,  other than any such  limitations  set
forth  in laws  or  regulations  of  general  applicability  to  thrift  holding

Advance  Subsidiaries is a party and which is material to the business,  results
of  operations,  assets  or  financial  condition  of  Advance  and the  Advance

insurance  policy  or other  instrument  to which it is a party or by which  its
assets, business or operations may be bound or affected, whether entered into in
the ordinary course of business or otherwise and whether written or oral,  which
default or  non-compliance  would have a Material Adverse Effect,  and there has
not occurred  any event that with the lapse of time or the giving of notice,  or
both,  would  constitute  such a default  or  non-compliance  by  Advance or any
Advance Subsidiary.

         (c) Neither Advance nor any Advance Subsidiary is a party or has agreed
to enter into an exchange  traded or  over-the-counter  equity,  interest  rate,
foreign exchange or other swap, forward, future, option, cap, floor or collar or
any  other  contract  that  is  not  included  in  Advance's  audited  financial

risk mortgage  derivatives,"  "capped  floating rate notes" or "capped  floating
rate mortgage derivatives."

         2.13     Properties and Insurance.

         (a) All real and  personal  property  owned  by  Advance  or any of the
Advance Subsidiaries or presently used by them in their respective businesses is
in adequate  condition  (ordinary  wear and tear  excepted) and is sufficient to
carry on the  business of Advance and the Advance  Subsidiaries  in the ordinary
course of business consistent with their past practices. Advance and each of the
Advance  Subsidiaries has good and, as to owned real property,  marketable title
to all material  assets and  properties,  whether real or personal,  tangible or
intangible,  reflected in Advance's  consolidated  balance  sheet as of June 30,
2004, or owned and acquired  subsequent  thereto (except to the extent that such
assets and  properties  have been  disposed  of for fair  value in the  ordinary
course of business  since June 30,  2004),  subject to no  encumbrances,  liens,
mortgages, securities interests or pledges,

                                       16

consolidated  balance  sheet or the notes  thereto or have been  incurred in the
ordinary course of business after the date of such  consolidated  balance sheet,
(ii) statutory liens for amounts not yet delinquent or which are being contested
in good faith, (iii) such encumbrances,  liens, mortgages, securities interests,
pledges and title  imperfections  that are not in the aggregate  material to the

the Advance  Subsidiaries  taken as a whole, and (iv) with respect to owned real
property,  title  imperfections noted in title reports prior to the date hereof.
Advance and the Advance  Subsidiaries  as lessees have the right under valid and
subsisting  leases to occupy,  use,  possess and control all property  leased by
them in all  material  respects  as  presently  occupied,  used,  possessed  and
controlled by Advance and the Advance  Subsidiaries  and the consummation of the
transactions  contemplated hereby and by the Agreement of Merger will not affect
any such  right in a way that  would have a  Material  Adverse  Effect.  Advance
Disclosure  Schedule  2.13(a)  sets  forth an  accurate  listing  of each  lease
pursuant to which  Advance or any Advance  Subsidiary  acts as lessor or lessee,
including the expiration  date and the terms of any renewal options which relate

Advance and the  Advance  Subsidiaries  are insured for its benefit  against all

shall  direct  and use their  reasonable  best  efforts  to cause  each of their
employees,  investment bankers, financial advisors,  attorneys,  accountants and
other  agents and  representatives  not to,  directly or  indirectly,  initiate,
solicit, encourage, facilitate any inquiries or hold discussions or negotiations
with,  or provide any  information  to, any person,  entity or group (other than
Parkvale and the Bank)  concerning  any merger,  sale of  substantial  assets or
liabilities  not in the ordinary  course of business,  sale of shares of capital
stock or similar  transactions  involving Advance or any Advance  Subsidiary (an
"Acquisition   Transaction");   provided,  however,  that  Advance  may  provide
information in connection with an unsolicited possible  Acquisition  Transaction
if the Board of  Directors  of  Advance,  after  receiving  advice  of  counsel,
determines in good faith that the failure to do so would or could  reasonably be
expected to constitute a breach of its fiduciary  duties under  applicable  law.
Advance and Advance Savings agree that they will immediately  cease and cause to
be terminated  any existing  activities,  discussions or  negotiations  with any
parties  conducted  heretofore  with  respect  to any  Acquisition  Transaction.
Advance will promptly communicate to Parkvale the terms of any proposal which it
may receive in respect of any such Acquisition Transaction.

         4.04 Current Information. During the period from the date hereof to the
Effective   Time,   each  party  will  cause  one  or  more  of  its  designated
representatives  to confer on a monthly or more frequent  basis, as either party
may reasonably  request,  with  representatives of the other party regarding its
business,  operations,  prospects,  assets and  financial  condition and matters
relating to the completion of the transactions  contemplated  hereby.  Within 25
days after the end of each month,  each party shall provide the other party with
a statement of financial condition and a statement of earnings,  without related
notes, for such month prepared in accordance with past practices as presented to
its Board of Directors.  On a monthly basis,  Advance and Advance  Savings shall
furnish  Parkvale  with a report,  in such  detail as  reasonably  requested  by
Parkvale,  indicating  all loans which have been  originated,  purchased or sold
during  such  period  as well as all  applications  for  loans  which  have been
received  for  processing  ("pipeline  report")  subject to Advance  and Advance
Savings  maintaining  the  confidentiality  of the parties  associated with such
applications.

                                       27



         4.05     Access to Properties and Records; Confidentiality.

         (a) Advance and each of the Advance  Subsidiaries shall permit Parkvale
and its  representatives  reasonable  access,  upon  advance  notice,  to  their
properties,  and shall disclose and make available to Parkvale all books, papers
and records  relating to the assets,  stock ownership,  properties,  operations,
obligations and liabilities of Advance and the Advance Subsidiaries,  including,
but not limited to, all books of account  (including  the general  ledger),  tax
records,  minute  books of  directors'  and  stockholders'  meetings  (excluding
minutes  related to the  transactions  contemplated  by this  Agreement or other
Acquisition Transactions),  organizational documents, bylaws, material contracts
and agreements, filings with any regulatory authority, accountants' work papers,
litigation  files  (except to the extent  necessary to preserve  attorney-client
privilege),  plans  affecting  employees,  and any other business  activities or
prospects  in which  Parkvale may have a  reasonable  interest.  Advance and the
Advance  Subsidiaries  shall not be required to provide access to or to disclose
information  where such access or  disclosure  would  violate or  prejudice  the
rights of any customer or would contravene any law, rule,  regulation,  order or
judgment.  Advance  and each of the  Advance  Subsidiaries  will use their  best
efforts  to  obtain  waivers  of any  such  restriction  and in any  event  make
appropriate substitute disclosure  arrangements under circumstances in which the
restrictions of the preceding  sentence  apply.  Advance and each of the Advance
Subsidiaries  shall  make its  directors,  officers,  employees  and  agents and
authorized   representatives   (including   counsel   and   independent   public
accountants) available to confer with Parkvale and its representatives, provided
that such access shall be reasonably  related to the  transactions  contemplated
hereby and not unduly interfere with normal operations.

         (b)  All  information  furnished  previously  in  connection  with  the
transactions  contemplated by this Agreement or pursuant hereto shall be treated
as the sole property of the party furnishing the information until  consummation
of the Merger and,  if such  Merger  shall not occur,  the party  receiving  the
information shall, at the request of the party which furnished such information,
either  return to the party  which  furnished  such  information  or destroy all
documents  or  other  materials  containing,  reflecting  or  referring  to such
information;   shall  use  its  best  effort  to  keep   confidential  all  such
information; shall use such information only for the purpose of consummating the
transactions   contemplated  by  this  Agreement;  and  shall  not  directly  or
indirectly use such information for any competitive or commercial purposes.  The
obligation to keep such information  confidential shall continue for three years
from the date the proposed  Merger is  abandoned  but shall not apply to (i) any
information  which (A) the party  receiving  the  information  can  establish by
convincing  evidence  was  already  in its  possession  prior to the  disclosure
thereof to it by the party  furnishing the  information;  (B) was then generally
known to the  public;  (C) became  known to the  public  through no fault of the
party receiving the information; or (D) was disclosed to the party receiving the
information by a third party not bound by an obligation of  confidentiality;  or
(ii) disclosures  pursuant to a legal requirement or in accordance with an order
of a court of competent jurisdiction.

         (c)  No  investigation  by  either  of  the  parties  hereto  or  their
respective   representatives  shall  affect  the  representations,   warranties,
covenants or agreements of the other party set forth herein.

                                       28



         4.06     Regulatory Matters.

         (a) Each of  Advance,  Advance  Savings,  Parkvale  and the Bank  shall
cooperate  with each other and use their best  efforts to prepare all  necessary
documentation  to effect all necessary  filings  within 30 days from the date of
this  Agreement and to obtain all  necessary  permits,  consents,  approvals and
authorizations  of all  third  parties  and  governmental  bodies  necessary  to
consummate  the   transactions   contemplated  by  this  Agreement  as  soon  as
practicable.  The  parties  shall each have the right to review  and  approve in
advance all  information  relating to the other,  as the case may be, and any of
their respective subsidiaries, which appears in any filing made with, or written
material  submitted to, any third party or governmental  body in connection with
the transactions contemplated by this Agreement.

         (b) Each of the parties will  furnish  each other with all  information
concerning themselves, their directors, officers and stockholders and such other
matters as may be necessary or advisable  in  connection  with any  statement or
application made by or on behalf of them to any governmental  body in connection
with the Merger and the other transactions, applications or filings contemplated
by this Agreement.

         (c) Each of the parties will promptly furnish each other with copies of
written  communications  received  by  them  from,  or  delivered  by any of the
foregoing to, any governmental  body in connection with the Merger and the other
transactions, applications or filings contemplated by this Agreement.

         (d) Each of Advance and Parkvale agrees that if such party shall become
aware  prior to the  mailing  date of the  Proxy  Statement  of any  information
furnished  by such  party that would  cause any of the  statements  in the Proxy
Statement to be false or  misleading  with respect to any material  fact,  or to
omit to state any material  fact  necessary to make the  statements  therein not
false or misleading,  to promptly  inform the other parties  thereof and to take
the necessary steps to correct the Proxy Statement.

         4.07  Approval  of  Stockholders.  Advance  will  (a)  take  all  steps
necessary  to duly  call,  give  notice  of,  convene  and hold a meeting of its
stockholders  as soon as  reasonably  practicable,  but in no event  later  than
December  22,  2004,   for  the  purposes  of  securing  the  adoption  of  such
stockholders  of this  Agreement  and the  Agreement  of Merger,  provided  that
Advance  shall  not be  required  to hold the  meeting  by such  date if the SEC
selects the Proxy  Statement for review and delays in obtaining SEC clearance of
the Proxy  Statement  preclude the Proxy Statement from being mailed in a timely
manner prior to such date,  (b)  recommend to its  stockholders  the approval of
this  Agreement  and the Agreement of Merger and the  transactions  contemplated
hereby  and  thereby,  and use its  best  efforts  to  obtain,  as  promptly  as
practicable,  such approvals,  provided, however, that the Board of Directors of
Advance may fail to make such recommendation,  or withdraw, modify or change any
such recommendation, if such Board of Directors, after having consulted with and
considered the advice of outside counsel,  has determined in good faith that the
making of such recommendation or the failure to withdraw,  modify or change such
recommendation, would or could

                                       29



reasonably be expected to  constitute a breach of the  fiduciary  duties of such
directors under  applicable law, and (c) cooperate and consult with Parkvale and
the Bank with respect to the foregoing matters.  Notwithstanding anything to the
contrary  herein,  this Agreement and the Agreement of Merger shall be submitted
to the Advance  stockholders  at a duly called meeting of  stockholders  for the
purpose of  adopting  this  Agreement  and the  Agreement  of Merger and nothing
herein shall be deemed to relieve Advance of such obligation.

         4.08 Further  Assurances.  Subject to the terms and  conditions  herein
provided,  each of the parties hereto agrees to use its best efforts to take, or
cause to be taken,  all  reasonable  action and to do, or cause to be done,  all
things  necessary,  proper or advisable under applicable laws and regulations to
satisfy the  conditions to closing  contained  herein and to consummate and make
effective the  transactions  contemplated by this Agreement and the Agreement of
Merger.  In case at any time  after the  Effective  Time any  further  action is
necessary or desirable to carry out the purposes of this  Agreement,  the proper
officers  and  directors  of each  party to this  Agreement  shall take all such
necessary  action.  Nothing in this  section  shall be  construed to require any
party to participate in any threatened or actual legal,  administrative or other
proceedings (other than proceedings,  actions or investigations to which it is a
party or subject or threatened to be made a party or subject) in connection with
consummation  of the  transactions  contemplated  by this Agreement  unless such
party  shall  consent in advance  and in writing to such  participation  and the
other party agrees to reimburse and indemnify such party for and against any and
all costs and damages related thereto.

         4.09 Disclosure  Supplements.  From time to time prior to the Effective
Time,  each party will promptly  supplement or amend its  respective  Disclosure
Schedules delivered pursuant hereto with respect to any matter hereafter arising
which,  if existing,  occurring or known as of the date hereof,  would have been
required to be set forth or described in such Schedules or which is necessary to
correct any  information  in such Schedules  which has been rendered  inaccurate
thereby.  No supplement or amendment to such Schedules shall have any effect for
the purpose of determining satisfaction of the conditions set forth in Article V
or the compliance by Advance and the Advance Subsidiaries with the covenants set
forth in Section 4.01 hereof.

         4.10 Public Announcements.  The parties hereto shall approve in advance
the  substance  of  and  cooperate  with  each  other  in  the  development  and
distribution of all news releases and other public  disclosures  with respect to
this Agreement or any of the transactions  contemplated hereby, except as may be
otherwise  required by law or regulation  and as to which the parties  releasing
such  information have used their best efforts to discuss with the other parties
in advance.

         4.11  Failure to Fulfill  Conditions.  In the event that  either of the
parties  hereto  determines  that a condition to its  respective  obligations to
consummate the transactions  contemplated hereby cannot be fulfilled on or prior
to December 31, 2004 and that it will not waive that condition, it will promptly
notify the other party.  Parkvale and Advance will promptly  inform the other of
any facts  applicable to them, or their respective  directors or officers,  that
would be likely to prevent or

                                       30



materially delay approval of the Merger by any  governmental  authority or which
would otherwise prevent or materially delay completion of the Merger.

         4.12     Certain Post-Merger Agreements.

         The parties  hereto agree to the following  arrangements  following the
Effective Time:

         (a)  Transferred  Employees.  Subject to the provisions of this Section
4.12, all employees  immediately prior to the Effective Time who are employed by
Parkvale or the Bank  immediately  following  the Effective  Time  ("Transferred
Employees") will be covered by the employee benefit plans of Parkvale and/or the
Bank on substantially the same basis as any employee of Parkvale and/or the Bank
in a comparable position.  Notwithstanding the foregoing, Parkvale may determine
to  continue  any of the  Advance  Plans for  Transferred  Employees  in lieu of
offering  participation  in the  benefit  plans  of  Parkvale  and/or  the  Bank
providing  similar benefits (e.g.,  medical and  hospitalization  benefits),  to
terminate  or suspend any of the Advance  Plans,  or to merge any such  Benefits
Plans with the benefit plans of Parkvale and/or the Bank, provided the result is
the  provision  of  benefits to  Transferred  Employees  that are  substantially
similar to the benefits  provided to the  employees of Parkvale  and/or the Bank
generally. Except as specifically provided in this Section 4.12 and as otherwise
prohibited by law, Transferred Employees service with Advance or Advance Savings
shall be  recognized  as  service  with  Parkvale  or the Bank for  purposes  of
eligibility to participate  and vesting,  if applicable (but not for purposes of
benefit accrual) under the benefit plans of Parkvale and/or the Bank, subject to
applicable  break-in-service  rules.  However,  notwithstanding  anything to the
contrary herein,  Transferred  Employees shall not be eligible to participate in
the Parkvale Financial  Corporation Employee Stock Ownership Plan until the plan
year commencing in 2005.  Notwithstanding anything herein to the contrary, after
the Effective Time, (x) any amendment to, or grant of additional benefits under,
any Advance  Plan,  including  stock based plans (but not  including the Advance
ESOP or  Advance  401(k)  plan),  which  continues  to exist  subsequent  to the
Effective  Time,  shall require the prior consent of Parkvale,  and (y) Parkvale
may cause any of the Advance  Plans which  continue  to exist,  including  stock
based plans, to be amended in order to provide that employees of Parkvale or the
Bank may be participants in such plans.

         (b) Health  Plans.  Parkvale will use (i) its best efforts to cause any
pre-existing  condition,  limitation  or  exclusion  in its  medical,  long-term
disability  and life insurance  plans to not apply to  Transferred  Employees or
their  covered  dependents  who are covered  under a medical or  hospitalization
indemnity  plan  maintained by Advance or Advance  Savings on the Effective Time
and  who  then  change   coverage  to  Parkvale's  or  the  Bank's   medical  or
hospitalization indemnity health plan at the time such Transferred Employees are
first given the option to enroll and (ii) honor under such plans any deductibles
and annual  out-of-pocket  contributions  incurred by the Transferred  Employees
during the calendar year prior to the Effective Time.

         (c) Advance ESOP.  Advance shall take all necessary action to cause the
Advance ESOP to be  terminated as of the Effective  Time.  The aggregate  Merger
Consideration received by the Advance ESOP trustee in connection with the Merger
with respect to the unallocated shares of

                                       31



Advance  Common Stock shall be first  applied by the Advance ESOP trustee to the
full repayment of the Advance ESOP loan. The balance of the Merger Consideration
(if any)  received by the Advance ESOP  trustee with respect to the  unallocated
shares of Advance Common Stock shall be allocated as earnings to the accounts of
all  participants  in the Advance  ESOP who have  accounts  remaining  under the
Advance ESOP (whether or not such  participants are then actively  employed) and
beneficiaries  in proportion to the account  balances of such  participants  and
beneficiaries,  in accordance  with the Advance  ESOP's terms and  conditions in
effect as of the date of this Agreement,  to the maximum extent  permitted under
the Code and applicable law, except as set forth in Advance Disclosure  Schedule
4.12(c).  The accounts of all participants and beneficiaries in the Advance ESOP
immediately  prior to the  Effective  Time shall  become  fully vested as of the
Effective  Time. As soon as practicable  after the date hereof,  but in no event
later than 60 days after the date of this Agreement, Advance shall file or cause
to be filed all necessary documents with the IRS for a determination  letter for
termination  of the Advance  ESOP as of the  Effective  Time,  with a copy to be
provided  to  Parkvale  and its  counsel  no later  than five days  prior to its
filing.  As soon as  practicable  after the later of the  Effective  Time or the
receipt of a favorable  determination  letter for termination  from the IRS, the
account  balances in the Advance ESOP shall be distributed to  participants  and
beneficiaries or transferred to an eligible  individual  retirement account as a
participant  or  beneficiary  may  direct.  Prior  to  the  Effective  Time,  no
prepayments  shall be made on the  Advance  ESOP loan and  contributions  to the
Advance ESOP and payments on the Advance ESOP loan shall be made consistent with
past practices on the regularly scheduled payment dates.

         (d) Advance  401(k) Plan.  Advance shall take all  necessary  action to
cause the Advance  Financial Savings Bank Employee's Profit Sharing Plan & Trust
("Advance   401(k)  Plan")  to  be  terminated   prior  to  the  Effective  Time
("Termination  Date"). The accounts of all participants and beneficiaries in the
Advance  401(k) Plan shall become fully vested as of the  Termination  Date.  As
soon as  practicable  after the date hereof,  but in no event later than 60 days
after the date of this  Agreement,  Advance  shall file or cause to be filed all
necessary  documents with the IRS for a determination  letter for termination of
the Advance 401(k) Plan as of the  Termination  Date, with a copy to be provided
to  Parkvale  and its counsel no later than five days prior to its  filling.  As
soon as practicable  after the later of the Termination Date or the receipt of a
favorable  determination  letter  for  termination  from  the IRS,  the  account
balances in the Advance  401(k) Plan shall be  distributed  as a participant  or
beneficiary may direct, consistent with applicable laws and regulations.

         (e) Existing Employment Agreements.  In satisfaction of the obligations
of  Advance  Savings  under  its  employment   agreement  with  Mr.   Gagliardi,
concurrently with the execution of this Agreement Parkvale,  Advance and Advance
Savings shall enter into a  Termination  and Release  Agreement  with Stephen M.
Gagliardi  as set  forth in  Exhibit D hereto.  Parkvale  shall  honor the other
employment  agreements  of  Advance  Savings,  in  effect as of the date of this
Agreement,  each of which is disclosed on Advance  Disclosure  Schedule 4.12(d),
which schedule  describes and quantifies in reasonable detail the maximum amount
of payments and benefits  which could become due and payable to each such person
(assuming the Merger is consummated  on or before  December 31, 2004) under each
of the employment agreements as a result of a termination of employment and/or a

                                       32



change in control of Advance or Advance Savings. As of the date hereof, the Bank
shall enter into an Addendum to each such agreement in the form and substance as
set forth at Exhibit F hereto.

         (f)  Consulting and  Noncompetition  Agreement.  Concurrently  with the
execution  of  this  Agreement,  Parkvale  shall  enter  into a  Consulting  and
Noncompetition  Agreement  with  Stephen M.  Gagliardi as set forth in Exhibit E
hereto.

         (g)  Employee  Severance.  Any  person who is  currently  serving as an
employee of either Advance or Advance Savings and continues as such  immediately
prior to the  Effective  Time (other than those  employees  covered by a written
employment  or change in  control  agreement  set  forth in  Advance  Disclosure
Schedule  2.08(j))  whose  employment  is  discontinued  by Parkvale or the Bank
(including  those employees who are asked to transfer to other positions  and/or
locations of Parkvale or the Bank and choose not to do so) within one year after
the  Effective  Time (unless  termination  of such  employment  is for Cause (as
defined  below))  shall be entitled to a severance  payment  from the Bank in an
amount equal to one week's salary for each year of service at Advance or Advance
Savings,  with a minimum  benefit of one week of salary and a maximum benefit of
ten (10)  weeks of salary and the  continuation  of  participation  in the group
health  insurance  plans sponsored by Parkvale or Advance without the payment of
premiums by the former  employee or dependents  for a period of two months.  For
purposes of this Section 4.12(f),  "Cause" shall mean termination because of the
employee's personal  dishonesty,  incompetence,  willful  misconduct,  breach of
fiduciary duty involving personal profit,  intentional failure to perform stated
duties or willful  violation of any law, rule or regulation  (other than traffic
violations or similar offenses).  Advance and Advance Savings agree to terminate
their Change in Control  Severance  Pay Plan prior to the Effective  Time.  With
respect to accrued but unused  sick leave and  vacation  pay as of December  31,
2004,  the employees of Advance and Advance  Savings will receive the benefit of
such leave in accordance with current Advance policies. In periods subsequent to
December 31,  2004,  the  employees of Advance and Advance  Savings will receive
accruals  for unused sick leave and  accruals and payouts for vacation pay based
upon the policies of the Bank.

         (h)  Indemnification.  Parkvale shall  indemnify and hold harmless each
present and former director, officer and employee of Advance and Advance Savings
determined  as of the Effective  Time (the  "Indemnified  Parties")  against any
costs or expenses  (including  reasonable  attorneys' fees),  judgments,  fines,
losses,  claims,  damages or  liabilities  (collectively,  "Costs")  incurred in
connection with any claim,  action, suit,  proceeding or investigation,  whether
civil,  criminal,  administrative  or  investigative,  arising  out  of  matters
existing or occurring at or prior to the  Effective  Time,  whether  asserted or
claimed prior to, at or after the Effective Time  (collectively,  "Claims"),  to
the  fullest  extent to which  such  Indemnified  Parties  were  entitled  under
Delaware law or under the Certificate of Incorporation  and Bylaws of Advance or
Advance  Savings  as in  effect  on the date  hereof,  for a period of six years
following  the  Effective   Time;   provided,   however,   that  all  rights  to
indemnification  in respect to any claim  asserted  or made  within  such period
shall continue until the final  disposition of such claim.  Indemnified  Parties
shall be third-party beneficiaries to this Section 4.12(g).

                                       33



         Any  Indemnified  Party  wishing  to claim  indemnification  under this
Section 4.12(g),  upon learning of any such claim, action,  suit,  proceeding or
investigation,  shall  promptly  notify  Parkvale,  but the failure to so notify
shall not relieve  Parkvale  of any  liability  it may have to such  Indemnified
Party if such failure does not materially  prejudice  Parkvale.  In the event of
any such claim,  action,  suit,  proceeding or  investigation  (whether  arising
before or after the Effective Time), (i) Parkvale shall have the right to assume
the defense thereof and Parkvale 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 Parkvale  elects not to assume such defense or if counsel for the
Indemnified  Parties  advises  that there are issues  which raise  conflicts  of
interest between Parkvale and the Indemnified  Parties,  the Indemnified Parties
may retain counsel which is reasonably  satisfactory  to Parkvale,  and Parkvale
shall pay, promptly as statements therefor are received, the reasonable fees and
expenses of such counsel for the  Indemnified  Parties (which may not exceed one
firm in any  jurisdiction  unless the use of one  counsel  for such  Indemnified
Parties  would  present  such  counsel  with a conflict of  interest),  (ii) the
Indemnified  Parties will cooperate in the defense of any such matter, and (iii)
Parkvale  shall not be liable  for any  settlement  effected  without  its prior
written consent, which consent shall not be withheld unreasonably.

         In the event  that  Parkvale  or any of its  respective  successors  or
assigns (i)  consolidates  with or merges into any other entity and shall not be
the  continuing  or surviving  corporation  or entity of such  consolidation  or
merger or (ii) transfers all or  substantially  all of its properties and assets
to any entity,  then,  and in each such case, the successors and assigns of such
entity shall assume the  obligations  set forth in this Section  4.12(g),  which
obligations  are expressly  intended to be for the  irrevocable  benefit of, and
shall be enforceable by, each of the Indemnified Parties.

         (i)  Insurance.  Parkvale and the Bank shall  maintain a directors' and
officers'  liability  insurance  policy  covering  the  Indemnified  Parties  in
connection  with any Claims for a period of three (3) years after the  Effective
Time,  provided that the total  premium cost of such  coverage  shall not exceed
175% of the current  premium paid by Advance (the  "Insurance  Amount").  If the
cost of the coverage  exceeds the Insurance  Amount,  then Parkvale and the Bank
shall use their  reasonable best efforts to obtain as much comparable  insurance
as is available for the Insurance Amount.

         (j)  Payout  of  Options.  In  accordance  with  Section  1.07  of  the
Agreement,  Advance or Advance  Savings will pay out, as of the Effective  Time,
the amounts  necessary to settle the awards under the Advance  Stock Option Plan
with the holders of such awards to execute  releases in a form  satisfactory  to
Parkvale.

         (k) Advisory  Board.  Subject to the  fiduciary  duties of the Board of
Directors of Parkvale,  each  director of Advance as of the date hereof shall be
requested  by  Parkvale  to serve as  members  of an  Advisory  Board  for three
consecutive  one-year  terms  following the Effective  Time.  The members of the
Advisory  Board  shall  meet  quarterly  and be paid a fee of $275  per  meeting
attended.  Within 12 months  following the Effective  Time,  the Advisory  Board
shall  nominate  one of its  members  to  become a  director  of  Parkvale.  The
Nominating Committee of the Board of Directors

                                       34



of Parkvale shall consider such nomination as well as the  qualifications of the
other members of the Advisory Board and shall  recommend that one of the members
of the Advisory  Board be  appointed  to the  Parkvale  Board of Directors on or
shortly after the one-year  anniversary of the Effective Time. After considering
the foregoing  nomination  and  recommendation,  the Parkvale Board of Directors
shall  select  and  appoint  a member of the  Advisory  Board as a  director  of
Parkvale.  Following such  appointment,  the newly  appointed  director shall no
longer serve as a member of the Advisory Board.

         (l)  Parkvale  shall  honor the  obligations  to retired  directors  of
Advance Savings as set forth in Advance  Disclosure  Schedule 2.12(a).  No other
directors shall become entitled to benefits under the Retirement Policy.

         4.13.  Certain  Policies.  Prior to the Effective Time, each of Advance
and  Advance  Savings  shall,  consistent  with  generally  accepted  accounting
principles, the rules and regulations of the SEC and applicable banking laws and
regulations,  modify or change its loan,  real estate owned,  accrual,  reserve,
tax, 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 Parkvale and the Bank; provided,  however,  that no such
modifications  or  changes  need  be  made  prior  to  the  satisfaction  of the
conditions set forth in Section 5.02; and further provided that in any event, no
accrual or reserve made by Advance or Advance  Savings  pursuant to this Section
4.13 shall  constitute or be deemed to be a Material  Adverse  Effect or breach,
violation  of or failure  to satisfy  any  representation,  warranty,  covenant,
agreement,  condition  or other  provision  of this  Agreement  or  otherwise be
considered in  determining  whether any such Material  Adverse Effect or breach,
violation or failure to satisfy shall have occurred; and provided, further, that
any such changes shall not result in Advance's filing of materially inconsistent
documents or reports with the  Securities  and Exchange  Commission or any other
governmental  authority.  The  recording  of any such  adjustments  shall not be
deemed to imply any misstatement of previously furnished financial statements or
information  and  shall  not be  construed  as  concurrence  of  Advance  or its
management with any such adjustments.

         4.14 Advance Rights Plan. If requested by Parkvale, Advance shall cause
the preferred  share purchase  rights issued pursuant to the Advance Rights Plan
to be redeemed  or  terminated  and shall  cause the  Advance  Rights Plan to be
terminated, in each case effective at or prior to the Effective Time and without
material cost to Parkvale.

         4.15 Amendment to Advance's  Bylaws.  Prior to the Effective  time, the
Board of  Directors  of  Advance  shall  amend the  Bylaws of  Advance to delete
Sections 15, 16 and 17 of Article III of the Bylaws.

         4.16 Supplemental Indenture. Prior to the Effective Time, Advance shall
take all  actions  necessary  to enter into a  supplemental  indenture  with the
Trustee of the  Indenture  dated  December  19, 2002 for  Advance's  outstanding
floating rate junior subordinated deferrable interest debentures to evidence the
succession of Parkvale as of the Effective Time. The form of the supplemental

                                       35



indenture  shall be reasonably  acceptable to Parkvale,  and Parkvale  agrees to
assume  the  covenants,   agreements  and  obligations  of  Advance  under  such
Indenture.

                                    ARTICLE V

                               CLOSING CONDITIONS

         5.01 Conditions to the Parties'  Obligations Under This Agreement.  The
respective  obligations of the parties under this Agreement  shall be subject to
the fulfillment at or prior to the Effective Time of the following conditions:

         (a) All necessary  regulatory,  governmental or third party  approvals,
waivers,  clearances,  authorizations and consents (including without limitation
the requisite approval and/or non- objection,  if any, of the Department and the
OTS required to consummate the transactions contemplated hereby) shall have been
obtained  without any  non-standard  term or condition  which, in the reasonable
opinion of  Parkvale,  would  materially  impair  the value of  Advance  and the
Advance  Subsidiaries  taken as a whole to Parkvale and the Bank; all conditions
required  to be  satisfied  prior  to the  Effective  Time by the  terms of such
approvals and consents  shall have been  satisfied;  and all waiting  periods in
respect thereof shall have expired.

         (b) All  corporate  action  necessary to authorize  the  execution  and
delivery of this Agreement and the Agreement of Merger and  consummation  of the
transactions  contemplated  hereby and thereby  shall have been duly and validly
taken by Parkvale,  the Bank,  Interim,  Advance and Advance Savings,  including
approval by the requisite vote of the  stockholders of Advance of this Agreement
and the Agreement of Merger.

         (c) No order,  judgment or decree shall be outstanding  against a party
hereto or a third party that would have the effect of  preventing  completion of
the Merger;  no suit,  action or other proceeding shall be pending or threatened
by any  governmental  body in which it is sought to  restrain  or  prohibit  the
Merger;  and no suit,  action or other  proceeding  shall be pending  before any
court or  governmental  agency in which it is sought to restrain or prohibit the
Merger or obtain other substantial  monetary or other relief against one or more
of the parties hereto in connection with this Agreement and which Parkvale,  the
Bank, Advance or Advance Savings determines in good faith, based upon the advice
of their  respective  counsel,  makes it  inadvisable to proceed with the Merger
because any such suit,  action or proceeding  has a significant  potential to be
resolved in such a way as to deprive the party electing not to proceed of any of
the material benefits to it of the Merger.

         5.02. Conditions to the Obligations of Parkvale and the Bank Under This
Agreement.  The  obligations of Parkvale and the Bank under this Agreement shall
be further  subject to the  satisfaction,  at or prior to the Effective Time, of
the following conditions, any one or more of which may be waived by Parkvale and
the Bank to the extent permitted by law:

                                       36



         (a) Each of the obligations of Advance and Advance Savings  required to
be  performed  by them at or prior to the Closing  pursuant to the terms of this
Agreement  shall have been duly  performed  and  complied  with in all  material
respects and the  representations  and warranties of Advance and Advance Savings
contained  in this  Agreement  shall  have been true and  correct as of the date
hereof and as of the  Effective  Time as though made at and as of the  Effective
Time, except (i) as to any representation or warranty which specifically relates
to an earlier  date,  or (ii) where the facts  which  caused the  failure of any
representation  or  warranty  to  be so  true  and  correct  would  not,  either
individually  or in the aggregate,  constitute a Material  Adverse  Effect,  and
Parkvale and the Bank shall have received a certificate to that effect signed by
the President of Advance and Advance Savings.

         (b)  All  permits,  consents,   waivers,   clearances,   approvals  and
authorizations  of all regulatory or  governmental  authorities or third parties
which are necessary in connection with the consummation of the Merger shall have
been  obtained,  and  none  of  such  permits,  consents,  waivers,  clearances,
approvals and  authorizations  shall contain any non-standard  term or condition
which would materially impair the value of Advance and the Advance  Subsidiaries
to Parkvale and the Bank.

         (c) Advance and Advance  Savings shall have furnished  Parkvale and the
Bank with such  certificates  of its officers or others and such other documents
to evidence  fulfillment  of the  conditions  set forth in this  Section 5.02 as
Parkvale and the Bank may reasonably request.

         5.03 Conditions to the Obligations of Advance and Advance Savings Under
this  Agreement.  The  obligations  of Advance  and Advance  Savings  under this
Agreement  shall be  further  subject  to the  satisfaction,  at or prior to the
Effective  Time,  of the following  conditions,  any one or more of which may be
waived by Advance and Advance Savings to the extent permitted by law:

         (a) Each of the  obligations  of Parkvale  and the Bank  required to be
performed  by them at or  prior to the  Closing  pursuant  to the  terms of this
Agreement  shall have been duly  performed  and  complied  with in all  material
respects  and the  representations  and  warranties  of  Parkvale  and the  Bank
contained  in this  Agreement  shall  have been true and  correct as of the date
hereof and as of the  Effective  Time as though made at and as of the  Effective
Time, except (i) as to any representation or warranty which specifically relates
to an earlier  date or (ii)  where the facts  which  caused  the  failure of any
representation  or  warranty  to  be so  true  and  correct  would  not,  either
individually  or in the aggregate,  constitute a Material  Adverse  Effect,  and
Advance and Advance  Savings shall have  received a  certificate  to that effect
signed by the President and Chief Executive Officer of Parkvale and the Bank.

         (b)  Parkvale  and the Bank shall have  furnished  Advance  and Advance
Savings  with  such  certificates  of its  officers  or  others  and such  other
documents to evidence  fulfillment  of the  conditions set forth in this Section

                                       37



         (c) Parkvale shall provide confirmation to Advance that an amount equal
to the Aggregate Merger  Consideration  in immediately  available funds has been
deposited by Parkvale with the Exchange Agent.

                                   ARTICLE VI

                     TERMINATION, AMENDMENT AND WAIVER, ETC.

         6.01 Termination. This Agreement may be terminated at any time prior to
the Effective  Time,  whether before or after approval of this Agreement and the
Agreement of Merger by the stockholders of Advance:

         (a) by mutual written consent of the parties hereto;

         (b) by  Parkvale,  the Bank,  Advance  or  Advance  Savings  (i) if the
Effective  Time shall not have occurred on or prior to June 30, 2005, or (ii) if
a vote of the  stockholders  of Advance is taken and such  stockholders  fail to
approve  this   Agreement  and  the  Agreement  of  Merger  at  the  meeting  of
stockholders  (or any  adjournment  thereof) of Advance  contemplated by Section
4.07 hereof;  unless the failure of such occurrence  shall be due to the failure
of the party  seeking to  terminate  this  Agreement  to perform or observe  its
agreements in all material respects set forth herein to be performed or observed
by such party at or before the Effective Time;

         (c) by Parkvale or Advance upon written  notice to the other 30 or more
days after the date upon which any  application for a regulatory or governmental
approval   necessary  to  consummate  the  Merger  and  the  other  transactions
contemplated  hereby  shall  have been  denied or  withdrawn  at the  request or
recommendation of the applicable  regulatory  agency or governmental  authority,
unless  within  such  30-day  period a  petition  for  rehearing  or an  amended
application  is filed or  noticed,  or 30 or more days  after any  petition  for
rehearing or amended application is denied;

         (d) by  Parkvale  or the Bank in writing if Advance or Advance  Savings
has,  or by Advance or Advance  Savings in writing if  Parkvale or the Bank has,
breached (i) any covenant or undertaking contained herein or in the Agreement of
Merger, or (ii) any  representation or warranty  contained herein,  which breach
would have a Material  Adverse  Effect,  in any case if such breach has not been
cured by the earlier of 30 days after the date on which  written  notice of such
breach is given to the party committing such breach or the Effective Time;

         (e) by Parkvale or Advance in writing,  if any of the  applications for
prior  approval  referred to in Section  4.06 hereof are denied or are  approved
contingent upon the  satisfaction of any  non-standard  condition or requirement
which,  in the reasonable  opinion of the Board of Directors of Parkvale,  would
materially  impair the value of Advance and Advance  Savings taken as a whole to
Parkvale,  and the time period for appeals and requests for  reconsideration has
run; or

                                       38



         (f) by  Parkvale  in the event of a  Termination  Event (as  defined in
Section 7.01(c) hereof).

         6.02  Effect  of  Termination.  In the  event  of  termination  of this
Agreement by Parkvale,  the Bank,  Advance or Advance Savings as provided above,
this Agreement shall forthwith become void (other than Sections 4.05(b) and 7.01
hereof,  which  shall  remain in full force and  effect)  and there  shall be no
further  liability  on the part of the parties or their  respective  officers or
directors  except for the  liability of the parties under  Sections  4.05(b) and
7.01 hereof and except for liability for any breach of this Agreement.

         6.03 Amendment, Extension and Waiver. Subject to applicable law, at any
time prior to the  consummation of the Merger,  whether before or after approval
thereof by the stockholders of Advance, the parties may (a) amend this Agreement
and the Agreement of Merger,  (b) extend the time for the  performance of any of
the  obligations  or other  acts of the  other  parties  hereto,  (c)  waive any
inaccuracies in the  representations  and warranties  contained herein or in any
document  delivered  pursuant  hereto,  or (d) waive  compliance with any of the
agreements or conditions  contained herein;  provided,  however,  that after any
approval of the Merger by the stockholders of Advance, there may not be, without
further approval of such stockholders, any amendment or waiver of this Agreement
or the Agreement of Merger which  modifies  either the amount or the form of the
Merger Consideration to be delivered to stockholders of Advance.  This Agreement
and the  Agreement  of Merger  may not be  amended  except by an  instrument  in
writing  signed on behalf of each of the parties  hereto.  Any  agreement on the
part of a party  hereto to any  extension  or waiver  shall be valid only if set
forth in an  instrument  in  writing  signed on behalf of such  party,  but such
waiver or failure to insist on strict compliance with such obligation, covenant,
agreement  or  condition  shall not  operate  as a waiver of, or  estoppel  with
respect to, any subsequent or other failure.

                                   ARTICLE VII

                                  MISCELLANEOUS

         7.01     Expenses; Termination Fee.

         (a) Subject to the  provisions of Section  7.01(b)  hereof,  each party
hereto  shall bear and pay all costs and expenses  incurred by it in  connection
with  the  transactions  contemplated  by this  Agreement,  including  fees  and
expenses of its own financial  consultants,  accountants and counsel,  provided,
however, that in the event of a willful breach of any representation,  warranty,
covenant or agreement  contained in this Agreement,  the non-breaching party may
pursue any remedy  available at law or in equity to enforce its rights and shall
be paid by the breaching  party for all damages,  costs and expenses,  including
without limitation legal, accounting,  investment banking and printing expenses,
incurred or suffered by the non-breaching party in connection herewith or in the
enforcement of its rights hereunder.

                                       39





         (b) Notwithstanding any provision in this Agreement to the contrary, in
         order to induce Parkvale to enter into this Agreement and as a means of
         compensating  Parkvale for the substantial direct and indirect monetary
         and other  damages and costs  incurred and to be incurred in connection
         with this Agreement in the event the transactions  contemplated  hereby
         do not occur as a result of a  Termination  Event (as defined  herein),
         Advance  agrees to pay  Parkvale,  and  Parkvale  shall be  entitled to
         payment of, a fee (the "Fee") of $1.5 million upon the  occurrence of a
         Termination  Event so long as the  Termination  Event occurs prior to a
         Fee  Termination   Event  (as  defined  herein).   The  parties  hereto
         acknowledge  that the actual  amount of such damages and costs would be
         impracticable or extremely difficult to determine,  and that the sum of
         $1.5 million constitutes a reasonable estimate by the parties under the
         circumstance  existing as of the date of this Agreement of such damages
         and  costs.  Such  payment  shall be made to  Parkvale  in  immediately
         available  funds within five  business  days after the  occurrence of a
         Termination  Event. A Fee Termination Event shall be the first to occur
         of the  following:  (i)  the  Effective  Time,  (ii)  12  months  after
         termination  of this Agreement in accordance  with its terms  following
         the first  occurrence  of a Preliminary  Termination  Event (as defined
         herein),  (iii)  termination of this  Agreement in accordance  with the
         terms  hereof  prior  to the  occurrence  of a  Termination  Event or a
         Preliminary  Termination  Event  (other  than  a  termination  of  this
         Agreement by Parkvale pursuant to Section 6.01(d) hereof as a result of
         a willful breach of any representation, warranty, covenant or agreement
         of Advance or Advance  Savings) or (iv) 12 months after the termination
         of this Agreement by Parkvale  pursuant to Section  6.01(d) hereof as a
         result of a willful breach of any representation, warranty, covenant or
         agreement of Advance or Advance Savings.

         (c) For purposes of this  Agreement,  a "Termination  Event" shall mean
         any of the following events:

         (i) Advance or Advance  Savings,  without  having  received  Parkvale's
         prior written  consent,  shall have entered into an agreement to engage
         in an  Acquisition  Transaction  with any person (the term "person" for
         purposes  of this  Agreement  having the  meaning  assigned  thereto in
         Sections  3(a)(9) and 13(d)(3) of the Securities  Exchange Act of 1934,
         as amended ("Exchange Act"), and the rules and regulations thereunder),
         other than  Parkvale  or any  subsidiary  of  Parkvale  or the Board of
         Directors of Advance shall have  recommended  that the  stockholders of
         Advance approve or accept any Acquisition  Transaction  with any person
         other than Parkvale or any subsidiary of Parkvale; or

         (ii) any person,  other than Parkvale,  shall have acquired  beneficial
         ownership (as such term is defined in Rule 13d-3  promulgated under the
         Exchange Act) of or the right to acquire beneficial  ownership,  or any
         "group" (as such term is defined in Section  13(d)(3)  of the  Exchange
         Act) shall have been formed which beneficially owns or has the right to
         acquire  beneficial  ownership of, 25% or more of the aggregate  voting
         power represented by the outstanding Advance Common Stock.

         (d) For purposes of this Agreement,  a "Preliminary  Termination Event"
         shall mean any of the following events:

                                       40



         (i) any person (other than Parkvale) shall have commenced (as such term
         is defined in Rule 14d-2 under the Exchange Act), or shall have filed a
         registration  statement  under the  Securities  Act of 1933, as amended
         ("Securities Act") with respect to, a tender offer or exchange offer to
         purchase  any  shares  of  Advance   Common   Stock  such  that,   upon
         consummation  of such offer,  such  person  would own or control 10% or
         more of Advance Common Stock  outstanding (such an offer being referred
         to herein as a "Tender  Offer" and an "Exchange  Offer,"  respectively,
         regardless of whether the  provisions of  Regulations  14D or 14E under
         the Exchange Act apply to such Tender Offer or Exchange Offer);

         (ii) (A) the holders of Advance  Common  Stock shall not have  approved
         this Agreement at the meeting of such stockholders held for the purpose
         of voting on this Agreement,  (B) such meeting shall not have been held
         or shall have been canceled  prior to  termination  of the Agreement or
         (C) Advance's  Board of Directors shall have withdrawn or modified in a
         manner  adverse to Parkvale the  recommendation  of Advance's  Board of
         Directors with respect to the Agreement,  in each case after any person
         (other than Parkvale) shall have (x) made, or disclosed an intention to
         make, a bona fide proposal to Advance or its  stockholders to engage in
         an  Acquisition  Transaction  (and,  in the case of clause (A)  hereof,
         which  bona fide  proposal  has been made  public  by  announcement  or
         written  communication  that  is  or  becomes  the  subject  of  public
         disclosure),  (y)  commenced  a Tender  Offer  or filed a  registration
         statement under the Securities Act with respect to an Exchange Offer or
         (z) filed an  application  or given  notice,  whether in draft or final
         form,  with the  appropriate  regulatory  authorities  for  approval to
         engage in an Acquisition Transaction; or

         (iii)   Advance   or  Advance   Savings   shall   have   breached   any
         representation,  warranty,  covenant or  obligation  contained  in this
         Agreement  and such breach would  entitle  Parkvale to  terminate  this
         Agreement  under Section  6.01(d)  hereof  (without  regard to the cure
         period  provided  for therein  unless  such cure is  promptly  effected
         without  jeopardizing  consummation of the Merger pursuant to the terms
         of this  Agreement)  after any person (other than Parkvale)  shall have
         (x) made,  or disclosed  an intention to make, a bona fide  proposal to
         Advance or its  stockholders  to engage in an Acquisition  Transaction,
         (y) commenced a Tender Offer or filed a  registration  statement  under
         the  Securities  Act with respect to an Exchange  Offer or (z) filed an
         application or given notice,  whether in draft or final form,  with the
         appropriate  regulatory  authorities  for  approval  to  engage  in  an
         Acquisition Transaction.

         (e) Advance shall promptly notify Parkvale in writing of the occurrence
         of any Preliminary Termination Event or Termination Event.

         7.02 Survival. The respective representations, warranties and covenants
of the parties to this Agreement  shall not survive the Effective Time but shall
terminate as of the Effective Time,  except for the provisions of Sections 1.07,
1.08, 4.12 and 7.01 hereof.
