$11.40 per share,  payable net to the seller in cash, upon the terms and subject
to the  conditions  set forth in this Offer to  Purchase  and in the  associated
Letter of Transmittal.

What is the market price for the common stock  compared to the purchase price in
the Offer?

On March 17, 2006,  the closing price for the shares as reported by the American
Stock  Exchange was $10.00 per share.  We encourage you to obtain current market
quotations for The Wilber Corporation  shares. The trading symbol for The Wilber
Corporation shares is "GIW."

What will happen if more than 650,000 shares are tendered?

If more than 650,000 shares are tendered,  we may purchase tendered shares:  (i)
first from any shareholder who owned, beneficially or of record, as of the close
of business on March 17, 2006 and continues to own,  beneficially  or of record,
as of the  Expiration  Date of the Offer (as defined  herein),  an  aggregate of
fewer than 100 shares and who validly tenders all of his or her shares; and (ii)
then,  subject to proration  as  described  in this Offer to Purchase,  from all
other  tendering  shareholders.  This means that we will not purchase all of the
shares  that  you may  tender  to us if too  many  shares  are  tendered  by our
shareholders,  unless you  qualify as an "odd lot"  holder as  described  in (i)
above. In the event more than 650,000 shares are validly tendered, we may decide
to purchase  additional  shares in an amount up to 2% of our outstanding  shares
(currently equal to about 222,919 shares).

What is the purpose of the Offer?

Prior to announcing our offer, we have considered a variety of alternative  uses
of our excess capital. After considering these alternatives,  we have determined
that investing in our shares would result in a more optimal  capital  structure.
Our Offer also  provides our  shareholders  who are  considering a sale of their
shares with the opportunity, if those shares are purchased in our Offer, to sell
those shares for cash without the usual  transaction  costs associated with open
market sales.  See Section 9 of this Offer to Purchase for more  information  on
our purpose in making the offer.

How do I tender shares that I hold in certificate form ?

If you  hold  your  shares  in  certificate  form,  you must  return a  properly
completed  Letter of Transmittal and any other documents  required by the Letter
of Transmittal, together with the certificates for the shares being tendered, to
our depositary,  Registrar and Transfer Company (the "Depositary").  These items
must be received by the  Depositary  by 5:00 p.m.,  New York City Time on May 4,
2006, unless the offer is extended.

How do I tender my shares if they are held by my broker?

If your shares are registered in street name with a broker,  dealer,  commercial
bank, trust company or other nominee, you will need to contact your broker, bank
or other  nominee and instruct the nominee to make the tender of your shares for
you. You cannot tender your shares using the Letter of  Transmittal  even though
you may have  received  one for your  information.  If you are a broker  and are
tendering shares in book-entry form for your customers, you must comply with the
book-entry delivery procedure described in Section 3 of this Offer to Purchase.

What if I can't deliver my shares in time?

If you  want  to  tender  your  shares  but  your  share  certificates  are  not
immediately  available  or cannot be  delivered  to the  Depositary  before  the
Expiration Date, the procedure for book-entry  transfer cannot be completed on a
timely  basis,  or time will not  permit  all  required  documents  to reach the
Depositary  before the  Expiration  Date,  you can still  tender  your shares by
following the guaranteed delivery procedure described in Section 3 of this Offer
to Purchase.

                                       1


What if I can't deliver my shares in time?

If you  want  to  tender  your  shares  but  your  share  certificates  are  not
immediately  available  or cannot be  delivered  to the  Depositary  before  the
Expiration Date, the procedure for book-entry  transfer cannot be completed on a
timely  basis,  or time will not  permit  all  required  documents  to reach the
Depositary  before the  Expiration  Date,  you can still  tender  your shares by
following the guaranteed delivery procedure described in Section 3 of this Offer
to Purchase.

Do I have to sell my shares?

No.  Shareholders are not required to tender any shares, and there is no minimum
or maximum number of shares that must be tendered.

What happens if I do not tender my shares?

Your  shares of The Wilber  Corporation  common  stock will  remain  outstanding
without a change in their terms or ownership  rights.  You will  continue to own
the same  number of shares  without  any  adjustment,  and you will  continue to
receive the same  dividend  and voting  rights on a per share basis as any other
shareholder.  However,  if we  purchase  shares  as  described  in the  Offer to
Purchase,  the percentage of the outstanding  shares which you own will increase
because the number of outstanding shares will be reduced and there will be other
effects.  See Section 9 of this Offer to Purchase for more  information on these
effects.

What if the terms of the Offer change?

In the event the  Expiration  Date is  extended or if the terms of the Offer are
materially  changed,  we will  generally  give notice of the  change,  and for a
period of at least 5 business days, and under certain  circumstances at least 10
business  days from the  notice,  you will be able to change  or  withdraw  your
tender.

Is there any brokerage commission?

No. We will  purchase  shares  directly  from each  shareholder  at the purchase
price.  However, if you hold your shares through a broker or other nominee,  you
should  check to see if they will impose a charge for  tendering  shares on your
behalf.

Can I change or cancel my tender?

You may  increase or decrease  the number of shares  indicated  in the Letter of
Transmittal  or withdraw  it entirely up until 5:00 p.m.,  New York City Time on
the  Expiration  Date,  which  currently  is May 4, 2006.  Generally,  after the
Expiration  Date,  you cannot  withdraw your tender.  If you desire to change or
withdraw  your  tender,  you  are  responsible  to  make  certain  that a  valid
withdrawal is received by the deadline. Except as discussed in Section 4 of this
Offer to Purchase,  tenders are irrevocable  after the May 4, 2006 deadline.  If
you hold your shares through a bank, broker or other nominee,  that bank, broker
or nominee may have an earlier deadline to change or withdraw your tender.

                                       2


Is The Wilber  Corporation  making  any  recommendation  about  whether I should
tender my shares

Neither The Wilber  Corporation  nor our board of  directors  or  officers,  the
Dealer  Manager/Information  Agent or the Depositary makes any recommendation to
any  shareholder  as to whether to tender all or any shares.  You must make your
own  decision  as to whether to tender  shares  and,  if so, how many  shares to
tender.

How can I get help in completing  the Letter of  Transmittal  or in tendering my
shares?

You may call our dealer  manager/information  agent, Sandler O'Neill & Partners,
L.P. (the "Dealer  Manager/Information  Agent"),  toll free at (800) 635-6851 to
get assistance on such matters.


How can I get additional tender offer materials?

If you  need  additional  tender  offer  materials,  you  may  call  the  Dealer
Manager/Information  Agent,  toll free at (800) 635-6851 between  9:00 a.m.  and

To the Holders of Shares of Common Stock of The Wilber Corporation

                                     SUMMARY

         The Wilber  Corporation is inviting its  shareholders to sell shares of
its common stock back to The Wilber  Corporation  for cash.  Set forth below are
the material terms of this Offer to Purchase:

         o  The Wilber  Corporation  will  purchase up to 650,000  shares of its
            common stock. See "Number of Shares; Proration" in Section 1 of this
            document.

         o  The Wilber  Corporation  will  purchase  these shares within a price
            range of $9.90 to  $11.40  per  share  as  determined  by  tendering
            shareholders. See "Number of Shares; Proration" in Section 1 of this
            document.

         o  Each shareholder  must determine  whether to sell stock, how much to
            sell,  and at what price the  shareholder is willing to sell. If you
            wish to sell your stock  without  specifying a price,  you may check
            the  appropriate box on the  accompanying  Letter of Transmittal and
            your shares will be considered to be tendered at the Purchase  Price
            determined  by the  Company,  referred  to in this  document  as the
            "Purchase Price". See "Number of Shares; Proration" in Section 1 and
            "Procedures for Tendering  Shares" in Section 3 of this document and
            in the Letter of Transmittal.

         o  All shares  will be  purchased  at the same  price.  See  "Number of
            Shares; Proration" in Section 1 of this document.

         o  If more than  650,000  shares are  tendered at or below the Purchase
            Price,  The Wilber  Corporation  will first  acquire  shares held by
            persons  who own less than 100 shares and then will  acquire  shares
            from other tendering  shareholders on a pro rata basis.  See "Number
            of Shares;  Proration" in Section 1 and "Tenders by Holders of Fewer
            Than 100 Shares" in Section 2 of this document.

         o  The Offer to Purchase is not conditioned  upon any minimum number of
            shares being tendered. The Offer to Purchase is, however, subject to
            other conditions. See "Conditions of the Offer" in Section 7 of this
            document.

         o  You must  properly  complete and execute the Letter of  Transmittal,
            which must be  received by 5:00 p.m.  New York City Time,  on May 4,
            2006 in order to sell your  shares to us in this Offer to  Purchase.
            See "Procedure for Tendering Shares" in Section 3 of this document.

         o  This Offer to Purchase is  scheduled to expire at 5:00 p.m. New York
            City Time,  on May 4, 2006.  See  "Number of Shares;  Proration"  in
            Section 1 of this document.

         o  The Company may extend the  offering  period at any time in its sole
            discretion  and will announce any such extension in a press release.
            See "Extension of Tender Period; Termination; Amendments" in Section
            16 of this document.

                                       1


         o  Shareholders  may withdraw  tendered shares at any time prior to the
            expiration of the Offer to Purchase, which is currently scheduled to
            occur on May 4, 2006. Tenders will then be irrevocable until May 31,
            2006 when they may be  withdrawn  by  shareholders  if they have not
            been accepted for payment by The Wilber Corporation. See "Withdrawal
            Rights" in Section 4 of this document.

         o  Written notice of a withdrawal  must be provided to the  Depositary.
            The information  required and method of notification is different if
            you hold your shares  directly or through a broker.  See "Withdrawal
            Rights" in Section 4 of this document.

         o  Once the price is set,  conditional  tenders and prorations  will be
            considered.  Then checks for all accepted  tenders will be issued by
            the Depositary. See "Acceptance for Payment of Shares and Payment of
            Purchase Price" in Section 5 of this document.

         o  The Wilber Corporation  expects to announce the final results of any
            proration  within seven  trading  days of the  Expiration  Date,  as
            defined  in  Section 1. See  "Acceptance  for  Payment of Shares and
            Payment of Purchase Price" in Section 5 of this document.

         o  Shareholders  who don't  tender  their  shares will  increase  their
            percentage ownership in the Company. These shareholders will include
            those executive officers and directors of The Wilber Corporation who
            do not tender any of their  shares.  We have been  advised  that one
            director  intends  to tender up to an  aggregate  of  120,000 of his
            beneficially  owned shares.  The Bank, as trustee for various trusts
            it administers,  plans to tender up to an aggregate of 69,520 of the
            shares of the  Company  held by such  trusts.  See  "Purpose  of the
            Offer;  Certain  Effects of the Offer" in Section 9 and "Interest of
            Directors  and Officers;  Transaction  and  Arrangements  Concerning
            Shares" in Section 12 of this document.

         o  Generally,  for  federal  income  tax  purposes,  shareholders  will
            recognize  a gain  or a loss on the  tendered  shares  equal  to the
            difference  between the cash paid by The Wilber  Corporation and the
            shareholder's  tax basis.  See "Federal Income Tax  Consequences" in
            Section 15 of this document.

1.       NUMBER OF SHARES; PRORATION

         Upon the terms and subject to the conditions described in this document
and in the Letter of  Transmittal,  we will purchase up to 650,000 shares of the
common stock of The Wilber  Corporation that are validly tendered on or prior to
the  Expiration  Date of the Offer to Purchase,  and not withdrawn in accordance
with  Section  4, at a price,  determined  in the manner  set forth  below,  not
greater than $11.40 nor less than $9.90 per share.  The later of 5:00 p.m.,  New
York City Time,  on May 4, 2006,  or the latest time and date to which the Offer
to  Purchase  is  extended  pursuant to Section 16, is referred to herein as the
"Expiration  Date." If this Offer to Purchase  is  oversubscribed  as  described
below,  only shares  tendered at or below the Purchase  Price on or prior to the
Expiration  Date will be  eligible  for  proration.  The  proration  period also
expires on the Expiration Date.

                                       2


         The Wilber  Corporation  will  determine the Purchase Price taking into
consideration  the  number  of  shares  tendered  and the  prices  specified  by
tendering  shareholders.  We will  select  the lowest  Purchase  Price that will
enable us to purchase  650,000  shares,  or such  lesser  number of shares as is
validly  tendered and not withdrawn,  at prices not greater than $11.40 nor less
than $9.90 per share, pursuant to this Offer to Purchase. Subject to Section 16,
we may, and we reserve the right to,  purchase an  additional  amount of shares,
not to exceed 2% of our outstanding common shares, without amending or extending
our offer.  Based upon the 11,145,937 shares currently  outstanding,  this means
that we could elect to purchase up to an additional  222,919  shares,  which, at
the maximum purchase price of $11.40 per share, would be an additional  purchase
cost of $2,541,277, exclusive of associated costs and expenses. Although we will
consider  making such additional  purchases,  we have no obligation to do so and
you should not base your  decision on whether to tender your shares or the price
at which  you  tender  shares,  on the  expectation  that we will  purchase  any
additional shares.  Our decision whether to purchase  additional shares, and how
many of such additional shares are purchased,  will depend upon our assessments,
at the time that we must make our  decision  regarding  the purchase of any such
additional shares, of general market,  economic and business conditions,  and of
our strategic plans, financial condition,  results of operations,  liquidity and
capital resources.

         This Offer to Purchase  is not  conditioned  on any  minimum  number of
shares  being  tendered,  but it is  subject to certain  other  conditions.  See
Section 7.

         In accordance  with  Instruction 5 of the Letter of  Transmittal,  each
shareholder who wishes to tender shares must specify the price, not greater than
$11.40  nor less than $9.90 per share,  at which the  shareholder  is willing to
tender the shares. As promptly as practicable  following the Expiration Date, we
will determine the Purchase  Price,  not greater than $11.40 nor less than $9.90
per  share,  that we will pay for  shares  validly  tendered  and not  withdrawn
pursuant to this Offer to  Purchase,  taking  into  account the number of shares
tendered  and  the  prices  specified  by  tendering  shareholders.  All  shares
purchased  pursuant  to this Offer to  Purchase  will be  purchased  at the same
price.  All shares not purchased  pursuant to this Offer to Purchase,  including
shares  tendered  at prices  greater  than the  Purchase  Price and  shares  not
purchased because of proration or because they were  conditionally  tendered and
not accepted for purchase, will be returned to the tendering shareholders at our
expense as promptly as practicable following the Expiration Date.

         Upon the terms and subject to the conditions of this Offer to Purchase:
i) if  650,000  or fewer  shares  have  been  validly  tendered  at or below the
Purchase  Price and not  withdrawn on or prior to the  Expiration  Date, we will
purchase all the shares;  and ii) if more than 650,000  shares have been validly
tendered at or below the  Purchase  Price and not  withdrawn  on or prior to the
Expiration Date, we will purchase shares in the following order of priority:

                  (i)  first,  all  shares  validly  tendered  at or  below  the
         Purchase Price and not withdrawn on or prior to the Expiration  Date by
         or on behalf of any shareholder who owned beneficially, as of the close
         of business on March 17, 2006 and continues to own  beneficially  as of
         the  Expiration  Date,  an  aggregate  of fewer than 100 shares and who
         validly  tenders all of such shares  (partial and  conditional  tenders
         will not qualify for this  preference)  and completes the box captioned
         "Odd Lots" on the Letter of Transmittal; and

                                       3


                  (ii) then,  after  purchase  of all of the  foregoing  shares,
         subject to the conditional  tender  provisions  described in Section 6,
         all other shares  validly  tendered at or below the Purchase  Price and
         not withdrawn on or prior to the  Expiration  Date on a pro rata basis,
         if  necessary,  with  appropriate  adjustments  to avoid  purchases  of
         fractional shares.

         Promptly after the Expiration Date, we will announce the Purchase Price
and  commence  payment  for any  shares  purchased  pursuant  to this  Offer  to
Purchase. If, however,  proration of tendered shares is required: (i) because of
the difficulty in determining the number of shares validly  tendered;  (ii) as a
result of the "odd lot"  procedure  described in Section 2; or (iii) as a result
of the conditional  tender procedure  described in Section 6, we may not be able
to announce  the final  proration  factor or to commence  payment for any shares
purchased pursuant to this Offer to Purchase until  approximately seven American
Stock  Exchange  ("Amex(R)")  trading days after the  Expiration  Date.  If this
occurs,  preliminary  results of proration will be announced by press release as
promptly as practicable after the Expiration Date.  Holders of shares may obtain
such preliminary information from the Dealer Manager/Information Agent.

         We expressly reserve the right, in our sole discretion,  at any time or
from  time to time,  to extend  the  period  of time  during  which the Offer to
Purchase  is open by giving  oral or  written  notice of such  extension  to the
Depositary and making a public announcement  thereof.  See Section 16. There can
be no assurance, however, that we will exercise our right to extend the Offer to
Purchase.

         For purposes of the Offer to Purchase,  a "business  day" means any day
other than a Saturday, Sunday or federal holiday and consists of the time period
from 12:01 a.m. through 12:00 midnight, New York City Time.

         Copies of this Offer to Purchase and the related  Letter of Transmittal
are being mailed to record  holders of shares of The Wilber  Corporation  common
stock and will be furnished to brokers,  banks and similar  persons whose names,
or  the  names  of  whose  nominees,  appear  on our  shareholder  list  or,  if
applicable,  who are  listed as  participants  in a clearing  agency's  security
position listing for subsequent transmittal to beneficial owners of shares.

2.       TENDERS BY HOLDERS OF FEWER THAN 100 SHARES

         Unless our purchase would reduce the number of our shareholders to less
than 300 or would cause the  delisting of the shares on the Amex(R),  all shares
validly tendered at or below the Purchase Price and not withdrawn on or prior to
the Expiration Date by or on behalf of any shareholder who owned beneficially as
of the close of business on March 17, 2006, and continues to own beneficially as
of the Expiration Date, an aggregate of fewer than 100 shares,  will be accepted
for purchase  before  proration,  if any, of other tendered  shares.  Partial or
conditional  tenders  will  not  qualify  for  this  preference,  and  it is not
available to beneficial holders of 100 or more shares,  even if the holders have
separate stock  certificates for fewer than 100 shares.  By accepting this Offer
to Purchase,  a shareholder owning beneficially fewer than 100 shares will avoid
the payment of brokerage  commissions  and the applicable odd lot charge payable
in a sale of such shares in a transaction effected on a securities exchange.

                                       4


         As of March 17, 2006 there were  approximately 532 holders of record of
shares of The Wilber  Corporation.  Approximately  90 of these holders of record
held individually fewer than 100 shares and held in the aggregate  approximately
3,260 shares. Because of the large number of shares held in the names of brokers
and nominees, we are unable to estimate the number of beneficial owners of fewer
than 100 shares or the  aggregate  number of shares  they own.  Any  shareholder
wishing  to tender all of his or her shares  pursuant  to this  Section 2 should
complete the box captioned "Odd Lots" on the Letter of Transmittal.

3.       PROCEDURE FOR TENDERING SHARES

         To tender shares validly pursuant to the Offer to Purchase,  a properly
completed and duly executed Letter of Transmittal or facsimile thereof, together
with any required  signature  guarantees and any other documents required by the
Letter of  Transmittal,  must be received by the  Depositary  at its address set
forth on the back cover of this Offer to Purchase and either:  (i)  certificates
for the  shares  to be  tendered  must be  received  by the  Depositary  at such
address;  or (ii) the shares must be delivered  pursuant to the  procedures  for
book-entry transfer described below, and a confirmation of the delivery received
by the Depositary, in each case on or prior to the Expiration Date.

         In accordance with Instruction 5 of the Letter of Transmittal, in order
to tender shares pursuant to this Offer to Purchase, a shareholder must indicate
in the section captioned "Price (In Dollars) Per Share At Which Shares Are Being
Tendered" on the Letter of Transmittal  either:  (i) the price,  in multiples of
$0.10, at which the shares are being tendered; or (ii) that the shares are being
tendered  at  the  Purchase  Price  determined  by  The  Wilber  Corporation  in
accordance  with the terms of this Offer to Purchase.  For a tender of shares to
be valid,  a price box,  but only one price box, on each  Letter of  Transmittal
must be checked.

         Shareholders  wishing  to tender  shares  at more  than one price  must
complete  separate  Letters of  Transmittal  for each price at which  shares are
being tendered. The same shares cannot be tendered at more than one price.

         The  Depositary,  Registrar  and Transfer  Company,  will  establish an
account with respect to the shares  tendered at The  Depository  Trust  Company,
which is a book-entry transfer facility, and any financial institution that is a
participant in the system of the book-entry  transfer facility may make delivery
of shares by causing the  book-entry  transfer  facility to transfer such shares
into  the  Depositary's  account  in  accordance  with  the  procedures  of  the
book-entry  transfer  facility.  Although  delivery  of shares  may be  effected
through  book-entry  transfer,  a properly completed and duly executed Letter of
Transmittal or a manually signed copy thereof, or an agent's message, as defined
below,  together with any required  signature  guarantees and any other required
documents,  must, in any case, be  transmitted to and received by the Depositary
at its address set forth on the back cover of this Offer to Purchase on or prior
to the  Expiration  Date.  Delivery  of  required  documents  to the  book-entry
transfer facility in accordance with its procedures does not constitute delivery
to the Depositary and will not constitute a valid tender.

         The  term  "agent's  message"  means  a  message   transmitted  by  the
book-entry  transfer  facility to, and received by, the Depositary and forming a
part of a book-entry  confirmation,

                                       5


which  states that the  book-entry  transfer  facility  has  received an express
acknowledgment   from  the  participant  in  the  book-entry  transfer  facility
tendering the shares,  that the  participant has received and agrees to be bound
by the terms of the Letter of Transmittal  and that The Wilber  Corporation  may
enforce the agreement against the participant.

         Except as set forth below,  all  signatures on a Letter of  Transmittal
must  be  guaranteed  by a  firm  that  is a  member  of a  registered  national
securities exchange or the National Association of Securities Dealers,  Inc., or
by a  commercial  bank,  a trust  company,  a savings  bank,  a savings and loan
association  or a credit  union which has  membership  in an approved  signature
guarantee  medallion  program,  each of the  foregoing  being  referred to as an
"eligible  institution".  Signatures  on a  Letter  of  Transmittal  need not be
guaranteed if: (i) the Letter of Transmittal is signed by the registered  holder
of the shares,  which, for the purposes of this Section 3 includes a participant
in the book-entry  transfer  facility whose name appears on a security  position
listing as the holder of the shares,  tendered  therewith and the holder has not
completed the box entitled  "Special  Payment  Instructions" or the box entitled
"Special Delivery Instructions" on the Letter of Transmittal; or (ii) the shares
are tendered for the account of an eligible institution.  See Instructions 1 and
6 of the Letter of Transmittal.

         Guaranteed  Delivery.  If a shareholder  desires to tender shares under
the  tender  offer  and:  i)  the  shareholder's   share  certificates  are  not
immediately available; ii) the shareholder cannot deliver the share certificates
to the  Depositary  before the  Expiration  Date;  iii) the  shareholder  cannot
complete the procedure for  book-entry  transfer on a timely basis;  or iv) time
will not  permit  all  required  documents  to reach the  Depositary  before the
Expiration  Date, the shareholder may nevertheless  tender the shares,  provided
that the shareholder satisfies all of the following conditions:

            o the  shareholder  makes  the  tender  by or  through  an  eligible
guarantor institution;

            o the  Depositary  receives  by hand,  mail,  overnight  courier  or
facsimile  transmission,  before the Expiration  Date, a properly  completed and
duly  executed  notice  of  guaranteed  delivery  in the form we have  provided,
specifying  the price at which the  shareholder is tendering  shares,  including
(where  required) a guarantee by an eligible  guarantor  institution in the form
set forth in such notice of guaranteed delivery; and

            o the Depositary receives the share certificates, in proper form for
transfer,  or  confirmation  of  book-entry  transfer  of the  shares  into  the
Depositary's  account  at the  book-entry  transfer  facility,  together  with a
properly completed and duly executed Letter of Transmittal, or a manually signed
facsimile  thereof,  and  including  any required  signature  guarantees,  or an
agent's message,  and any other documents required by the Letter of Transmittal,
within three  Amex(R)trading days after the date of receipt by the Depositary of
the notice of guaranteed delivery

         The method of delivery of shares and all other required documents is at
the  option  and risk of the  tendering  shareholder.  If  delivery  is by mail,
registered mail with return receipt requested, properly insured, is recommended.
In all cases  sufficient time should be allowed to assure timely delivery to the
Depositary.

                                       6


         To prevent United States federal income tax backup withholding equal to
28% of the gross payments made pursuant to the Offer to Purchase, each tendering
shareholder must provide the Depositary with the shareholder's  correct taxpayer
identification  number and certain other information by properly  completing the
substitute Form W-9 included in the Letter of Transmittal. Foreign shareholders,
as defined in Section 15, must submit a properly  completed  Form W-8, which may
be obtained from the  Depositary,  in order to prevent  backup  withholding.  In
general,  backup  withholding  does not  apply  to  corporations  or to  foreign
shareholders subject to 30%, or lower treaty rate, withholding on gross payments
received  pursuant to the Offer to  Purchase,  as discussed in Section 15. For a
discussion of certain federal income tax consequences to tendering shareholders,
see  Section 15. Each  shareholder  is urged to consult  with his or her own tax
advisor  regarding  his,  her or its  qualification  for  exemption  from backup
withholding and the procedure for obtaining any applicable exemption.

         It is a  violation  of Rule  14e-4  promulgated  under  the  Securities
Exchange Act of 1934 ("Exchange Act"), as amended, for a person to tender shares
for his or her own account  unless the person so  tendering:  (i) has a net long
position equal to or greater than the amount of (x) shares tendered or (y) other
securities  immediately  convertible  into,  exercisable or exchangeable for the
amount of shares tendered and will acquire such shares for tender by conversion,
exercise or exchange of such other  securities;  and (ii) will cause such shares
to be delivered  in  accordance  with the terms of the Offer to  Purchase.  Rule
14e-4  provides  a similar  restriction  applicable  to the  tender of shares on
behalf of  another  person.  The  tender of  shares  pursuant  to any one of the
procedures   described  above  will   constitute  the  tendering   shareholder's
representation and warranty that: (1) the shareholder has a net long position in
the shares being tendered within the meaning of Rule 14e-4 promulgated under the
Exchange Act; and (2) the tender of such shares  complies  with Rule 14e-4.  Our
acceptance for payment of shares tendered pursuant to the Offer to Purchase will
constitute a binding agreement between the tendering shareholder and us upon the
terms and subject to the conditions of the Offer to Purchase.

         All  questions as to the Purchase  Price,  the form of  documents,  the
number of shares to be accepted and the validity, eligibility, including time of
receipt,  and  acceptance for payment of any tender of shares will be determined
by us, in our sole discretion, which determination shall be final and binding on
all  parties.  We reserve  the  absolute  right to reject any or all  tenders of
shares that we determine are not in proper form or the acceptance for payment of
or payment for shares that may, in the opinion of our counsel,  be unlawful.  We
also  reserve  the  absolute  right to waive any defect or  irregularity  in any
tender of any  particular  shares.  None of The Wilber  Corporation,  the Dealer
Manager/Information  Agent,  the  Depositary  or any other  person is or will be
under any duty to give  notice of any defect or  irregularity  in  tenders,  nor
shall any of them incur any liability for failure to give any such notice.

         Certificates for shares,  together with a properly  completed Letter of
Transmittal or, in the case of a book-entry  transfer,  an agent's message,  and
any other documents required by the Letter of Transmittal,  must be delivered to
the Depositary and not to The Wilber Corporation or to a branch office of Wilber
National Bank.  Any such documents  delivered to us will not be forwarded to the
Depositary and therefore will not be deemed to be properly tendered.

                                       7


4.       WITHDRAWAL RIGHTS

         Tenders  of  shares  made  pursuant  to the  Offer to  Purchase  may be
withdrawn  at any time prior to the  Expiration  Date.  Thereafter,  tenders are
irrevocable,  except that they may be withdrawn after 12:00  midnight,  New York
City Time,  on May 31,  2006  unless  previously  accepted  for payment by us as
provided in this Offer to Purchase. If we extend the period of time during which
the Offer to Purchase is open, are delayed in purchasing shares or are unable to
purchase shares pursuant to the Offer to Purchase for any reason,  then, without
prejudice to our rights under the Offer to Purchase,  the Depositary may, on our
behalf,  retain all shares tendered,  and the shares may not be withdrawn except
as otherwise  provided in this Section 4, and subject to Rule 13e-4(f)(5)  under
the Exchange Act,  which  provides that the issuer making the tender offer shall
either pay the consideration offered, or return the tendered securities promptly
after the termination or withdrawal of the tender offer.

         Withdrawal  of Shares Held in Physical  Form.  For a  withdrawal  to be
effective, a shareholder of shares held in physical form must provide a written,
telegraphic, or facsimile transmission notice of withdrawal to the Depositary at
its address  set forth on the back cover page of this Offer to  Purchase  before
the Expiration Date,  which notice must contain:  (i) the name of the person who
tendered the shares; (ii) a description of the shares to be withdrawn; (iii) the
certificate numbers shown on the particular  certificates evidencing the shares;
(iv)  the  signature  of the  shareholder  executed  in the same  manner  as the
original  signature  on the  Letter  of  Transmittal,  including  any  signature
guarantee, if such original signature was guaranteed;  and (v) if the shares are
held by a new beneficial owner,  evidence satisfactory to The Wilber Corporation
that the person withdrawing the tender has succeeded to the beneficial ownership
of the shares.  A purported notice of withdrawal which lacks any of the required
information will not be an effective withdrawal of a tender previously made.

         Withdrawal of Shares Held with the Book-Entry Transfer Facility.  For a
withdrawal to be effective,  a  shareholder  of shares held with the  book-entry
transfer  facility  must:  (i) call his or her broker and instruct the broker to
withdraw  the  tender of shares by  debiting  the  Depositary's  account  at the
book-entry  transfer facility for all shares to be withdrawn;  and (ii) instruct
the broker to provide a written,  telegraphic,  or facsimile transmission notice
of withdrawal to the Depositary on or before the Expiration  Date. The notice of
withdrawal  shall  contain:  (a) the name of the person who tendered the shares;
(b) a description of the shares to be withdrawn;  and (c) if the shares are held
by a  new  beneficial  owner,  evidence  satisfactory  to  us  that  the  person
withdrawing the tender has succeeded to the beneficial  ownership of the shares.
A purported  notice of  withdrawal  which lacks any of the required  information
will not be an effective withdrawal of a tender previously made.

         Any  permitted  withdrawals  of tenders of shares may not be rescinded,
and any shares so withdrawn will  thereafter be deemed not validly  tendered for
purposes of the Offer to Purchase;  provided, however, that withdrawn shares may
be  re-tendered  by following the tendering  procedures  prior to the Expiration
Date.

         All questions as to the form and validity,  including  time of receipt,
of any notice of withdrawal  will be  determined by us, in our sole  discretion,
which  determination  shall be final and  binding  on all  parties.  None of the
Company,  the Dealer  Manager/Information  Agent,  the

                                       8


Depositary or any other person is or will be under any duty to give notification
of any defect or irregularity in any notice of withdrawal or incur any liability
for failure to give any such notification.

5.       ACCEPTANCE FOR PAYMENT OF SHARES AND PAYMENT OF PURCHASE PRICE

         Upon the terms and subject to the  conditions of the Offer to Purchase,
and promptly  after the Expiration  Date, we will determine the Purchase  Price,
taking into consideration the number of shares tendered and the prices specified
by  tendering  shareholders,  announce the  Purchase  Price and,  subject to the
proration and conditional tender provisions of the Offer to Purchase, accept for
payment and pay the Purchase Price for shares validly tendered and not withdrawn
at or below the Purchase  Price.  Payment for all shares validly  tendered on or
prior to the Expiration  Date and accepted for payment  pursuant to the Offer to
Purchase  will be made by the  Depositary  by check as promptly as  practicable.
Payment for shares accepted  pursuant to the Offer to Purchase will be made only
after timely receipt by the Depositary of: (i)  certificates  for such shares or
confirmation  of a  book-entry  transfer of such  shares  into the  Depositary's
account at the book-entry transfer facility;  (ii) a properly completed and duly
executed  Letter of  Transmittal  or a manually  signed copy  thereof,  with any
required  signature  guarantees,  or in the case of a  book-entry  delivery,  an
agent's message; and (iii) any other required documents.

         For  purposes  of the  Offer to  Purchase,  we shall be  deemed to have
accepted  for  payment,   and  thereby  purchased,   subject  to  proration  and
conditional  tenders,  shares that are validly tendered and not withdrawn as, if
and when we give oral or written  notice to the Depositary of our acceptance for
payment  of the  shares.  In the  event  of  proration,  we will  determine  the
proration  factor and pay for those tendered shares accepted for payment as soon
as practicable after the Expiration Date.  However,  we do not expect to be able
to announce the final results of any such proration  until  approximately  seven
Amex(R)  trading days after the Expiration  Date. We will pay for shares that we
have  purchased  pursuant to the Offer to Purchase by  depositing  the aggregate
Purchase Price therefor with the  Depositary.  The Depositary  will act as agent
for  tendering  shareholders  for the purpose of  receiving  payment from us and
transmitting  payment to tendering  shareholders.  Under no  circumstances  will
interest be paid on amounts to be paid to tendering shareholders,  regardless of
any delay in making such payment.

         Certificates  for all shares not  purchased  pursuant  to this Offer to
Purchase  will be  returned,  or, in the case of shares  tendered by  book-entry
transfer,  the  shares  will be  credited  to an  account  maintained  with  the
book-entry  transfer  facility by the  participant  therein who so delivered the
shares, as promptly as practicable following the Expiration Date without expense
to the tendering shareholder.

         Payment  for  shares  may be  delayed  in the  event of  difficulty  in
determining the number of shares properly  tendered or if proration is required.
See Section 1. In addition,  if certain events occur, we may not be obligated to
purchase shares. See Section 7.

         We will pay or cause to be paid any stock  transfer  taxes with respect
to the sale and transfer of any shares to us or our order  pursuant to the Offer
to Purchase.  If, however,  payment of the Purchase Price is to be made to, or a
portion of the shares delivered,  whether in certificated form or by book-entry,
but not  tendered  or not  purchased  are to be  registered  in the name of, any


                                       9


person other than the registered holder, or if tendered shares are registered in
the name of any person other than the person signing the Letter of  Transmittal,
unless the person is signing in a  representative  or  fiduciary  capacity,  the
amount of any stock transfer taxes,  whether  imposed on the registered  holder,
such other person or otherwise, payable on account of the transfer to the person
will be deducted  from the Purchase  Price unless  satisfactory  evidence of the
payment of such taxes, or exemption therefrom,  is submitted.  See Instruction 7
to the Letter of Transmittal.

         Any tendering  shareholder  or other payee who fails to complete  fully
and sign the substitute  Form W-9 included in the Letter of  Transmittal  or, in
the case of a foreign individual, a Form W-8, may be subject to required federal
income tax withholding of 28% of the gross proceeds paid to such  shareholder or
other payee. See Section 3.

6.       CONDITIONAL TENDER OF SHARES

         As set  forth  in  Section  1, we may  prorate  the  number  of  shares
purchased  pursuant to the Offer to  Purchase.  As  discussed in Section 15, the
number of shares to be purchased from a particular  shareholder might affect the
tax treatment of the purchase for the shareholder and the shareholder's decision
whether to tender.  Each shareholder is urged to consult with his or her own tax
advisor.  Accordingly,  a shareholder may tender shares subject to the condition
that a specified minimum number of the shareholder's shares tendered pursuant to
a Letter  of  Transmittal  must be  purchased  if any  shares  so  tendered  are
purchased.  Any  shareholder  desiring  to  make a  conditional  tender  must so
indicate in the box captioned "Conditional Tender" in the Letter of Transmittal.

         Any tendering  shareholders  wishing to make a conditional  tender must
calculate and indicate in the Letter of Transmittal the minimum number of shares
to be tendered.  If the effect of accepting tenders on a pro rata basis would be
to reduce the number of shares to be purchased  from any  shareholder,  tendered
pursuant to a Letter of Transmittal,  below the minimum number so specified, the
tender will  automatically  be regarded as withdrawn,  except as provided in the
next  paragraph,  and all shares  tendered  by the  shareholder  pursuant to the
applicable  Letter of  Transmittal  will be returned as promptly as  practicable
thereafter.

         If conditional tenders that would otherwise be so regarded as withdrawn
would cause the total number of shares to be  purchased  to fall below  650,000,
then, to the extent  feasible,  we will select enough  conditional  tenders that
would otherwise have been so withdrawn to permit us to purchase  650,000 shares.
We will  select  by lot  among  these  conditional  tenders  and will  limit our
purchase  in  each  case to the  minimum  number  of  shares  designated  by the
shareholder in the applicable Letter of Transmittal as a condition to his or her
tender.

7.       CONDITIONS OF THE OFFER TO PURCHASE

         Notwithstanding  any other provision of the Offer to Purchase,  we will
not be  required  to accept for  payment or pay for any  shares  tendered,  and,
subject to the requirements of the Exchange Act for prompt payment for or return
of shares  tendered,  we may terminate or amend and may postpone the  acceptance
for payment of shares tendered, if at any time on or before the Expiration Date,
any of the following shall have occurred:

                                       10


                  (i) there shall have been  threatened,  instituted  or pending
         any action or proceeding by any government or governmental,  regulatory
         or administrative  agency or authority or tribunal or any other person,
         domestic or foreign, or before any court, authority, agency or tribunal
         that: (a) challenges the acquisition of shares pursuant to the Offer to
         Purchase or otherwise in any manner  relates to or affects the Offer to
         Purchase;  or (b) in the reasonable judgment of The Wilber Corporation,
         could  materially  and  adversely   affect  the  business,   condition,
         financial  or other,  income,  operations  or  prospects  of The Wilber
         Corporation  and/or  any of our  subsidiaries,  taken  as a  whole,  or
         otherwise  materially impair in any way the contemplated future conduct
         of  the  business  of  The  Wilber   Corporation   and/or  any  of  our
         subsidiaries or materially impair the Offer to Purchase's  contemplated
         benefits to us;

                  (ii) there shall have been any action  threatened,  pending or
         taken,  or  approval  withheld,  or  any  statute,   rule,  regulation,
         judgment,   order   or   injunction   threatened,   proposed,   sought,
         promulgated,  enacted,  entered,  amended,  enforced  or  deemed  to be
         applicable to the Offer to Purchase or The Wilber Corporation or any of
         our subsidiaries,  by any legislative body, court, authority, agency or
         tribunal  which,  in our sole  judgment,  would or  might  directly  or
         indirectly:  (a) make the  acceptance  for payment of, or payment  for,
         some or all of the shares  illegal or  otherwise  restrict  or prohibit
         consummation  of the  Offer to  Purchase;  (b)  delay or  restrict  the
         ability of The Wilber  Corporation,  or render us unable, to accept for
         payment or pay for some or all of the shares; (c) materially impair the
         contemplated benefits of the Offer to Purchase to us; or (d) materially
         affect the business, condition,  financial or other, income, operations
         or prospects of The Wilber  Corporation and/or any of our subsidiaries,
         taken  as a  whole,  or  otherwise  materially  impair  in any  way the
         contemplated  future conduct of the business of The Wilber  Corporation
         and/or any of our subsidiaries;

                  (iii) it shall have been  publicly  disclosed or we shall have
         learned that: (a) any person or "group,"  within the meaning of Section
         13(d)(3)  of the  Exchange  Act,  has  acquired  or proposes to acquire
         beneficial  ownership of more than 5% of the outstanding shares whether
         through the acquisition of stock,  the formation of a group,  the grant
         of any option or right,  or  otherwise,  other than as  disclosed  in a
         Schedule 13D or 13G on file with the Securities and Exchange Commission
         ("SEC") on May 4, 2006;  or (b) any person or group that on or prior to
         May 4, 2006 had  filed a  Schedule  13D or 13G with the SEC  thereafter
         shall have  acquired or shall propose to acquire,  whether  through the
         acquisition of stock, the formation of a group, the grant of any option
         or right,  or  otherwise,  beneficial  ownership of  additional  shares
         representing 2% or more of the outstanding shares;

                  (iv) there shall have occurred:  (a) any general suspension of
         trading in, or  limitation  on prices for,  securities  on any national
         securities  exchange  or  in  the  over-the-counter   market;  (b)  any
         significant  decline in the market  price of shares of the common stock
         of The Wilber  Corporation  or in the general level of market prices of
         equity securities in the United States or abroad; (c) any change in the
         general  political,  market,  economic or  financial  condition  in the
         United  States or abroad that could have a material  adverse  effect on
         our business,  condition,  financial or otherwise,  income, operations,
         prospects  or ability to obtain  financing  generally or the trading in
         the  shares;  (d)  the

                                       11


         declaration  of a banking  moratorium or any  suspension of payments in
         respect  of banks in the  United  States or any  limitation  on, or any
         event which, in our reasonable judgment,  might affect the extension of
         credit  by  lending   institutions  in  the  United  States;   (e)  the
         commencement  of a war, armed  hostilities,  acts of terrorism or other
         calamity directly or indirectly  involving the United States; or (f) in
         the  case  of  any  of  the  foregoing  existing  at  the  time  of the
         commencement of the Offer to Purchase,  in our reasonable  judgment,  a
         material acceleration or worsening thereof;

                  (v) a tender or exchange  offer with respect to some or all of
         our  shares of common  stock,  other than the Offer to  Purchase,  or a
         merger,  acquisition  or other  business  combination  proposal for The
         Wilber  Corporation,  shall have been  proposed,  announced  or made by
         another person or group,  within the meaning of Section 13(d)(3) of the
         Exchange Act; or

                  (vi) there  shall have  occurred  any event or events that has
         resulted,  or may in the reasonable  judgment of The Wilber Corporation
         result,  directly or indirectly,  in an actual or threatened  change in
         the business, condition,  financial or other, income, operations, stock
         ownership or prospects of The Wilber Corporation and our subsidiaries;

and, in the reasonable judgment of The Wilber Corporation,  such event or events
make it undesirable or inadvisable to proceed with the Offer to Purchase or with
such acceptance for payment.

         The foregoing  conditions are for the reasonable  benefit of The Wilber
Corporation and may be asserted by us regardless of the circumstances, including
any action or inaction by us, giving rise to any of these conditions, and any of
these  conditions may be waived by us, in whole or in part, at any time and from
time to time on or prior to the Expiration  Date, in our reasonable  discretion.
The  failure  by The  Wilber  Corporation  at any  time to  exercise  any of the
foregoing  rights  shall  not be  deemed a waiver of the right and each of these
rights  shall be deemed an ongoing  right  which may be asserted at any time and
from time to time. Any determination by us concerning the events described above
will be final and binding on all parties.

         Acceptance  of shares  validly  tendered  in the Offer to  Purchase  is
subject to the condition  that, as of the Expiration  Date, and after giving pro
forma  effect  to  the  acceptance  of  shares  validly  tendered,   The  Wilber
Corporation  would  continue  to have at least 300  shareholders  and our shares
would remain  listed for  quotation on the Amex(R).  This  condition  may not be
waived.

         The Exchange Act requires that all  conditions to the Offer to Purchase
must be satisfied or waived before the Expiration Date.

9.       PURPOSE  OF THE  OFFER TO  PURCHASE;  CERTAIN  EFFECTS  OF THE OFFER TO
         PURCHASE

         We believe that the purchase of the  Company's  shares is an attractive
use of a portion of The Wilber Corporation's available capital and is consistent
with our long-term  goal of  increasing  shareholder  value.  We believe we have
adequate  sources of capital to complete the share  repurchase,  while operating
our business and pursuing strategic opportunities.

         Through retained earnings accumulated from profitable  operations,  the
Company  has  built a  capital  base  that  exceeds  all  applicable  regulatory
standards, supports our banking business, and has permitted the Company to pay a
consistent  quarterly  dividend.  In addition to dividends,  we have taken other
steps to improve  performance and enhance the value of our franchise,  including
branch acquisitions, diversification of the Bank's lending business and periodic
share  repurchases.  Still, the Company's  capital remains high in proportion to
its earning assets, which affects our ability to produce desired returns for our
shareholders.  Our  management  and board of directors  has  concluded  that the
purchase of shares pursuant to the Offer to Purchase is an appropriate  means of
reducing these ratios and improving  returns for  shareholders,  consistent with
safe and sound banking practices.

         The Offer to Purchase is designed to  restructure  our balance sheet in
order to increase return on equity and earnings per share by reducing the amount
of equity and shares  outstanding.

                                       13


Based upon the current market price of our shares,  we believe that the purchase
of shares is an attractive  use of funds.  Following the purchase of the shares,
we believe funds provided by earnings, combined with other sources of liquidity,
will be fully  adequate to meet our funding  needs for the  foreseeable  future.
Upon  completion  of the Offer to  Purchase,  we expect that the Company and the
Bank will continue to maintain the highest regulatory capital standards.

         The Offer to Purchase will enable  shareholders who are considering the
sale of all or a portion of their shares to determine  the price or prices,  not
greater than $11.40 nor less than $9.90 per share,  at which they are willing to
sell  their  shares,  and,  if any  shares  are sold  pursuant  to the  Offer to
Purchase,  to sell those  shares for cash  without the usual  transaction  costs
associated  with  open-market  sales.  The  Offer  to  Purchase  may  also  give
shareholders the opportunity to sell shares at prices greater than market prices
prevailing prior to the announcement of the Offer to Purchase. See Section 8. In
addition, tendering shareholders owning beneficially fewer than 100 shares, will
avoid the payment of brokerage commissions and any applicable odd lot reductions
from the market price typically charged by brokers for executing odd lot trades.

         Shareholders  who do not tender or only  partially  tender their shares
pursuant  to the  Offer to  Purchase,  and  shareholders  who  retain  an equity
interest in the Company as a result of a  proration,  as described in Section 1,
will continue as owners of the Company,  with the attendant risks and rewards of
an investment in common stock. Shareholders will retain the right to receive the
payment of any dividends declared with respect to the tendered shares until such
shares are  accepted  for  payment.  As noted  above,  The  Wilber  Corporation,
following  completion  of the  Offer to  Purchase,  will  maintain  the  highest
regulatory capital rating.

         Shareholders  who  determine  not to accept the Offer to Purchase  will
realize a proportionate increase in their relative equity interest in The Wilber
Corporation and, thus, in The Wilber Corporation's  earnings and assets, subject
to any risks  resulting  from our  purchase  of shares and our  ability to issue
additional  equity  securities  in the future.  In  addition,  to the extent the
purchase of shares  pursuant to the Offer to Purchase  results in a reduction of
the number of shareholders of record, our costs for shareholder related services
may be reduced.

         If fewer than  650,000  shares are  purchased  pursuant to the Offer to
Purchase,  we may repurchase the remainder of the shares on the open market,  in
privately negotiated  transactions or otherwise. In the future, we may determine
to  purchase  additional  shares on the open  market,  in  privately  negotiated
transactions,  through one or more tender offers or otherwise. Any purchases may
be on the same  terms  as,  or on terms  which  are  more or less  favorable  to
shareholders  than,  the terms of the Offer to  Purchase.  Rule 13e-4  under the
Exchange Act,  however,  prohibits us and our  affiliates  from  purchasing  any
shares,  other than  pursuant to the Offer to Purchase,  until at least ten (10)
business days after the Expiration  Date. Any future  purchases of shares by The
Wilber  Corporation would depend on many factors,  including the market price of
the shares, our business and financial position,  regulatory  requirements,  and
general economic and market conditions.

         Shares we acquire pursuant to the Offer to Purchase will be restored to
the  status  of  authorized  and  unissued  shares,  or  placed  in  The  Wilber
Corporation's  treasury.  These shares will be available for us to issue without
further shareholder action, except as required by

                                       14


applicable law or the rules of the Amex(R) or any other  securities  exchange on
which the shares are listed,  for  purposes  including,  but not limited to, the
acquisition of other  businesses,  the raising of additional  capital for use in
our  business  and the  satisfaction  of  obligations  under  existing or future
employee  benefit  plans.  We have no current plans for reissuance of the shares
repurchased pursuant to the Offer to Purchase.

         Neither The Wilber  Corporation  nor our board of  directors  makes any
recommendation to any shareholder as to whether to tender all or any shares. The
Bank, in the exercise of its fiduciary  duties as the trustee of various  trusts
it administers which hold stock of the Company,  may make such  recommendations.
Each shareholder must make his or her own decision whether to tender shares and,
if so, how many  shares to tender and at what  price.  Directors,  officers  and
employees of The Wilber  Corporation who own shares may participate in the Offer
to Purchase on the same basis as our other  shareholders.  We have been  advised
that one director of The Wilber Corporation intends to tender up to an aggregate
of 120,000 of his  beneficially  owned shares pursuant to the Offer to Purchase.
The Bank, as trustee for various trusts it administers, plans to tender up to an
aggregate of 69,520 of the shares of the Company held by such trusts.

Notes to Unaudited Pro Forma Financial  Information (dollars in thousands except
share and per share data)

     1.   The pro forma financial information reflects the repurchase of 650,000
          shares at $9.90 and  $11.40  per share,  as  indicated.  The pro forma
          adjusted  balance  sheet  information  assumes  that such  shares were
          purchased at the applicable  price on December 31, 2005. The pro forma
          adjusted income  statement  information  assumes that such shares were
          purchased at the applicable price on January 1, 2005.

     2.   The  Company has  assumed  that the funds used to purchase  the shares
          would reduce its Federal Funds sold position,  an earning  asset.  For
          the purposes of the pro forma  adjusted  income  statement  data,  the
          Company  assumed a 4.50%  interest  rate on the funds used to purchase
          the shares.

     3.   The Company will incur certain costs in connection  with this Offer to
          Purchase.  The estimated costs are shown below and included in the pro
          forma adjusted income statement information above:

         Legal fees                                        $  30
         Dealer Manager / Information Agent fees              10
         Depositary fees                                      19
         SEC filing fees                                       2
         Printing, Mailing and Other Expenses                  8

                                       18


11.      SOURCE AND AMOUNT OF FUNDS

         Assuming  that we purchase  the maximum of 650,000  shares  pursuant to
this Offer to  Purchase  at the  highest  price of $11.40  per share,  the total
amount required by us to purchase these shares will be $7,410,000,  exclusive of
fees and other  expenses.  We intend to fund the  purchase  with  proceeds  of a
dividend  paid by the Bank to the Company,  which may require OCC approval if we
purchase  additional  shares in an amount  up to 2% of our  outstanding  shares.
Based upon the OCC  regulations  governing  the payment of dividends by national
banks, the Company believes that the OCC would approve such payment.

         Alternatively,  depending  on market,  general  economic,  business and
strategic  considerations,  we may decide to fund all or part of the purchase of
tendered shares through the issuance of trust preferred securities.  In general,
in a  trust  preferred  securities  transaction:  i) the  Company  would  form a
statutory  trust,  which  would  issue  the  trust  preferred  securities  to an
investor,  typically a special purpose pool vehicle established by an investment
bank or financial  advisory  firm;  ii) the trust would use the sale proceeds to
purchase a debenture from the Company;  iii) the trust would use the payments by
the Company on the  debenture  to pay the  principal  and  interest on the trust
preferred  securities;  and iv) the Company would guarantee  these payments.  In
recent years,  the issuance of trust  preferred  securities  has become a common
method of balance sheet  management and  transaction  financing for bank holding
companies  and  there has been an  abundant  supply of  capital  and  purchasers
available in the equity markets for the purchase of these  securities.  However,
the  Company  cannot  and does not make any  assurances  that  such  capital  or
purchasers would exist or be available should it decide to issue trust preferred
securities to fund its purchase of tendered  shares.  The Company's  issuance of
trust preferred  securities  would require the approval of the Federal  Reserve.
Based upon the Federal Reserve's  supervisory policies governing the issuance of
trust preferred securities by bank holding companies,  the Company believes that
the Federal Reserve would approve its issuance of such securities.

12.      INTEREST OF  DIRECTORS  AND  OFFICERS;  TRANSACTIONS  AND  ARRANGEMENTS
         CONCERNING SHARES

         As of March 17, 2006,  The Wilber  Corporation  had  11,145,937  shares
issued and  outstanding.  The 650,000  shares  that we are  offering to purchase
represent  approximately 5.83% of the Company's  outstanding shares. As of March
17, 2006, our directors and executive  officers as a group beneficially owned an
aggregate of 4,038,811 shares.  Directors,  officers and employees of The Wilber
Corporation  who own shares may participate in the Offer to Purchase on the same
basis as our other shareholders.  We have been advised that one of our directors
intends to tender a total of up to 120,000 beneficially owned shares pursuant to
the Offer to Purchase.  The Bank, as trustee for various trusts it  administers,
plans to tender up to an  aggregate  of 69,520 of the shares of the Company held
by such trusts.

         Assuming we  purchase  the  maximum of 650,000  shares  pursuant to the
Offer to Purchase,  our  executive  officers and  directors as a group would own
beneficially  approximately 38.48% of the Company's outstanding shares,  without
giving  effect to any shares  they may tender  that are  accepted  for  payment.
Pursuant to the terms of a trust  established under Florida

                                       19


law for tax planning  purposes by Brian R. Wright,  Chairman of the Board of the
Company, on February 28, 2006, legal title to the shares of the Company's common
stock held in the trust was transferred from the Bank to Mr. Wright.  Except for
this  transaction,  neither The Wilber  Corporation,  nor any  subsidiary of The
Wilber  Corporation  nor,  to the  best  of  our  knowledge,  any of The  Wilber
Corporation's  directors and executive officers, nor any affiliate of any of the
foregoing, had any transactions involving the shares during the 60 days prior to
the date hereof.

         Except as otherwise  described herein,  neither The Wilber  Corporation
nor, to the best of our knowledge, any of our affiliates, directors or executive
officers,  or  any  of  the  directors  or  executive  officers  of  any  of its
affiliates,  is  a  party  to  any  contract,   arrangement,   understanding  or
relationship  with any other person  relating,  directly or  indirectly,  to the
Offer to  Purchase  with  respect to any  securities  of The Wilber  Corporation
including,  but not  limited to, any  contract,  arrangement,  understanding  or
relationship concerning the transfer or the voting of any such securities, joint
ventures,  loan or  option  arrangements,  puts or calls,  guarantees  of loans,
guaranties  against loss or the giving or  withholding  of proxies,  consents or
authorizations.  Except as  disclosed  in this  Offer to  Purchase,  The  Wilber
Corporation,  its  directors  and  executive  officers  have no current plans or
proposals which relate to or would result in:

         o  the acquisition by any person of additional securities of The Wilber
            Corporation   or  the   disposition  of  securities  of  The  Wilber
            Corporation;

         o  an   extraordinary   corporate   transaction,   such  as  a  merger,
            reorganization  or liquidation  involving The Wilber  Corporation or
            any of the Company's subsidiaries;

         o  a purchase,  sale or transfer of a material  amount of assets of The
            Wilber Corporation or any of our subsidiaries;

         o  any change in present board of directors or management of The Wilber
            Corporation  other than the resignation of director Richard E. Keene
            who has reached the mandatory  retirement  age of 70 pursuant to the
            Company's  bylaws and the  election  at the  Company's  2006  Annual
            Meeting of nominee  Thomas  Davis as his  successor,  to serve for a
            three year term expiring on the date of the 2009 Annual Meeting.

         o  any  material  change in the  present  dividend  rate or policy,  or
            indebtedness or capitalization of The Wilber Corporation;

         o  any  other  material  change in  Company's  corporate  structure  or
            business;

         o  any change in our charter or bylaws or any actions  which may impede
            the acquisition of control of The Wilber Corporation by any person;

         o  a class of equity security of The Wilber  Corporation being delisted
            from a national securities exchange;

         o  a class of equity  securities  of The  Wilber  Corporation  becoming
            eligible  for  termination  of  registration   pursuant  to  Section
            12(g)(4) of the Exchange Act; or

         o  the suspension of our obligation to file reports pursuant to Section
            15(d) of the Exchange Act. See Section 10.

                                       20


13.      EFFECTS OF THE OFFER TO PURCHASE ON THE MARKET FOR SHARES; REGISTRATION
         UNDER THE EXCHANGE ACT

         The Wilber  Corporation's  purchase of shares pursuant to this Offer to
Purchase  will  reduce  the  number of shares  that  might  otherwise  be traded
publicly and may reduce the number of shareholders.  Nonetheless,  we anticipate
that there will be a sufficient number of shares outstanding and publicly traded
following  consummation  of the Offer to Purchase to ensure a continued  trading
market for the  shares.  Based upon  published  guidelines  of the  Amex(R),  we
believe that following our purchase of shares pursuant to the Offer to Purchase,
our remaining shares will continue to qualify to be quoted on the Amex(R).

         The Company's shares are currently "margin  securities" under the rules
of the Federal  Reserve.  This has the effect,  among other things,  of allowing
brokers to extend credit to their customers using such shares as collateral.  We
believe  that,  following  the  purchase  of  shares  pursuant  to the  Offer to
Purchase, the shares will continue to be "margin securities" for purposes of the
Federal Reserve's margin regulations.

         The  Company's  shares are  registered  under the Exchange  Act,  which
requires,  among  other  things,  that we  furnish  certain  information  to our
shareholders  and the SEC and comply with the SEC's  proxy  rules in  connection
with meetings of our shareholders. See Section 18.

14.      LEGAL MATTERS; REGULATORY APPROVALS

         If we  purchase  additional  shares  in  an  amount  up  to  2% of  our
outstanding shares, the payment of a dividend by the Bank to the Company to fund
the purchase may require OCC approval. Likewise, the Company's issuance of trust
preferred  securities  to fund all or part of the  purchase  of shares  tendered
would require the approval of the Federal Reserve. See Section 11.

         We are not aware of any license or regulatory permit that appears to be
material to our business that might be adversely  affected by our acquisition of
shares as contemplated herein.  Except for the OCC and Federal Reserve approvals
discussed  above,  we are not aware of any  approval or other  action by, or any
filing with,  any  government  or  governmental,  administrative  or  regulatory
authority  or  agency,  domestic  or  foreign,  including,  but not  limited  to
regulators having  jurisdiction  over anti-trust  matters that would be required
for the acquisition or ownership of shares by us as contemplated herein.  Should
any  approval or other action be required,  we  presently  contemplate  that the
approval or other  action  will be sought.  There can be no  assurance  that any
approval  or other  action,  if needed,  would be  obtained or would be obtained
without  substantial  conditions  or that the failure to obtain any  approval or
other  action  might not result in adverse  consequences  to our  business.  Our
obligations under the Offer to Purchase to accept for payment and pay for shares
is subject to certain conditions. See Section 7.

         The Bank Holding Company Act of 1956 and the Change in Bank Control Act
each  govern  acquisition  of control of bank  holding  companies.  As a general
matter,  a person may not acquire  control of a bank holding company such as The
Wilber Corporation  without the prior approval of the Federal Reserve.  If, as a
result of the offer,  any shareholder  becomes the beneficial owner of more than
10% of our  common  stock,  such  shareholder  may be  required  to  reduce  its
ownership  interest in The Wilber  Corporation or obtain regulatory  approval to

                                       21


continue  to own more  than  10%.  The  Company  urges  each  shareholder  whose
ownership  interest may be so increased to consult the  shareholder's  own legal
counsel with respect to the consequences to the shareholder of the tender offer.

15.      FEDERAL INCOME TAX CONSEQUENCES

         General.  The following is a discussion  of the material  United States
federal income tax consequences to shareholders with respect to a sale of shares
pursuant to the Offer to Purchase.  The  discussion is based upon the provisions
of the Internal Revenue Code of 1986, as amended, Treasury regulations, Internal
Revenue  Service  rulings and judicial  decisions,  all in effect as of the date
hereof and all of which are subject to change, possibly with retroactive effect,
by subsequent  legislative,  judicial or administrative  action.  The discussion
does not address all aspects of United States federal  income  taxation that may
be relevant to a particular shareholder in light of the shareholder's particular
circumstances or to certain types of holders subject to special  treatment under
the  United  States  federal  income  tax  laws,   such  as  certain   financial
institutions,  tax-exempt  organizations,  life insurance companies,  dealers in
securities or currencies,  employee  benefit plans or  shareholders  holding the
shares  as part of a  conversion  transaction,  as  part of a hedge  or  hedging
transaction,  or as a position in a straddle for tax purposes. In addition,  the
discussion  below does not consider the effect of any foreign,  state,  local or
other tax laws that may be applicable to particular shareholders. The discussion
assumes  that the  shares are held as  "capital  assets"  within the  meaning of
Section  1221 of the  Internal  Revenue  Code.  We have  neither  requested  nor
obtained a written  opinion of counsel  or a ruling  from the  Internal  Revenue
Service with respect to the tax matters discussed below.

         Each  shareholder  should  consult his or her own tax advisor as to the
particular  United States federal income tax  consequences  to that  shareholder
tendering  shares  pursuant to the Offer to Purchase and the  applicability  and
effect of any state,  local or foreign tax laws and recent changes in applicable
tax laws.

         Characterization  of the  Surrender of Shares  Pursuant to the Offer to
Purchase.  The  surrender of shares by a shareholder  to The Wilber  Corporation
pursuant  to the Offer to  Purchase  will be a taxable  transaction  for  United
States federal income tax purposes and may also be a taxable  transaction  under
applicable  state,  local and foreign tax laws. The United States federal income
tax  consequences  to a shareholder  may vary depending  upon the  shareholder's
particular  facts and  circumstances.  Under Section 302 of the Internal Revenue
Code,  the  surrender  of  shares by a  shareholder  to The  Wilber  Corporation
pursuant to the Offer to  Purchase  will be treated as a "sale or  exchange"  of
shares  for  United  States  federal  income  tax  purposes,  rather  than  as a
distribution  by The Wilber  Corporation  with respect to the shares held by the
tendering   shareholder,   if  the  receipt  of  cash  upon   surrender  (i)  is
"substantially  disproportionate" with respect to the shareholder,  (ii) results
in  a  "complete  redemption"  of  the  shareholder's  interest  in  The  Wilber
Corporation, or (iii) is "not essentially equivalent to a dividend" with respect
to the shareholder, each as described below.

         If any of the above three tests is satisfied,  and the surrender of the
shares is therefore  treated as a "sale or exchange" of shares for United States
federal income tax purposes,  the tendering  shareholder  will recognize gain or
loss  equal  to the  difference  between  the  amount  of cash  received  by the
shareholder and the shareholder's tax basis in the shares  surrendered

                                       22


pursuant  to the Offer to  Purchase.  Any gain or loss will be  capital  gain or
loss,  and will be long term  capital  gain or loss if the shares have been held
for more than one year.

         If  none  of  the  above  three  tests  is  satisfied,   the  tendering
shareholder  will be treated as having  received  a  distribution  by The Wilber
Corporation with respect to the  shareholder's  shares in an amount equal to the
cash  received  by the  shareholder  pursuant  to the  Offer  to  Purchase.  The
distribution  will be treated as a dividend,  taxable as ordinary  income to the
extent of The Wilber  Corporation's  current or accumulated earnings and profits
for tax  purposes.  The  amount of the  distribution  in  excess  of The  Wilber
Corporation's  current or accumulated  earnings and profits will be treated as a
return of the shareholder's  tax basis in the shares,  and then as gain from the
sale or exchange of the shares. If a shareholder is treated as having received a
distribution by The Wilber  Corporation  with respect to his or her shares,  the
shareholder's  tax  basis  in his or her  remaining  shares  will  generally  be
adjusted  to take into  account the  shareholders  return of basis in the shares
tendered.

         Constructive  Ownership.  In determining whether any of the three tests
under Section 302 of the Internal Revenue Code is satisfied,  shareholders  must
take  into  account  not  only  the  shares  that  are  actually  owned  by  the
shareholder,  but also shares that are  constructively  owned by the shareholder
within the meaning of Section 318 of the Internal  Revenue  Code.  Under Section
318 of the Code, a shareholder may constructively own shares actually owned, and
in some cases  constructively  owned, by certain related individuals or entities
and shares  that the  shareholder  has the right to acquire  by  exercise  of an
option or by conversion.

         Proration.  Contemporaneous dispositions or acquisitions of shares by a
shareholder  or related  individuals  or entities  may be deemed to be part of a
single  integrated  transaction  and may be taken into  account  in  determining
whether any of the three tests under  Section 302 of the  Internal  Revenue Code
has been satisfied.  Each shareholder should be aware that because proration may
occur  in  the  Offer  to  Purchase,   even  if  all  the  shares  actually  and
constructively  owned by a  shareholder  are  tendered  pursuant to the Offer to
Purchase,  fewer  than  all of  these  shares  may be  purchased  by The  Wilber
Corporation.  Thus,  proration  may affect  whether the surrender of shares by a
shareholder  pursuant to the Offer to Purchase  will meet any of the three tests
under  Section 302 of the Code.  See Section 6 for  information  regarding  each
shareholder's option to make a conditional tender of a minimum number of shares.
A shareholder  should  consult his or her own tax advisor  regarding  whether to
make a conditional  tender of a minimum  number of shares,  and the  appropriate
calculation thereof.

         Section  302  Tests.  The  receipt  of  cash by a  shareholder  will be
"substantially  disproportionate" if the percentage of the outstanding shares in
The Wilber  Corporation  actually and  constructively  owned by the  shareholder
immediately  following the surrender of shares pursuant to the Offer to Purchase
is less  than 80% of the  percentage  of the  outstanding  shares  actually  and
constructively  owned by the shareholder  immediately  before the sale of shares
pursuant  to the  Offer to  Purchase.  Shareholders  should  consult  their  tax
advisors with respect to the application of the "substantially disproportionate"
test to their particular situation.

         The receipt of cash by a shareholder will be a "complete redemption" if
either  (i) the  shareholder  owns no shares in The  Wilber  Corporation  either
actually or constructively immediately after the shares are surrendered pursuant
to the Offer to Purchase, or (ii) the

                                       23


shareholder actually owns no shares in The Wilber Corporation  immediately after
the  surrender of shares  pursuant to the Offer to Purchase and, with respect to
shares  constructively  owned by the shareholder  immediately after the Offer to
Purchase,  the  shareholder  is  eligible  to  waive,  and  effectively  waives,
constructive  ownership of all such shares under procedures described in Section
302(c) of the  Internal  Revenue  Code.  A director,  officer or employee of The
Wilber  Corporation is not eligible to waive  constructive  ownership  under the
procedures described in Section 302(c) of the Internal Revenue Code.

         Even if the  receipt  of cash by a  shareholder  fails to  satisfy  the
"substantially  disproportionate"  test or the  "complete  redemption"  test,  a
shareholder  may  nevertheless  satisfy  the "not  essentially  equivalent  to a
dividend" test if the shareholder's surrender of shares pursuant to the Offer to
Purchase results in a "meaningful  reduction" in the  shareholder's  interest in
The Wilber  Corporation.  Whether the receipt of cash by a  shareholder  will be
"not  essentially  equivalent  to a dividend"  will  depend upon the  individual
shareholder's  facts  and  circumstances.   The  Internal  Revenue  Service  has
indicated in published  rulings that even a small reduction in the proportionate
interest of a small  minority  shareholder  in a publicly held  corporation  who
exercises no control over corporate  affairs may  constitute  such a "meaningful
reduction."  Shareholders expecting to rely upon the "not essentially equivalent
to a dividend" test should consult their own tax advisors as to its  application
in their particular situation.

         Corporate  Shareholder  Dividend  Treatment.  If a sale of  shares by a
corporate shareholder is treated as a dividend, the corporate shareholder may be
entitled to claim a deduction  equal to 70% of the dividend under Section 243 of
the  Internal  Revenue  Code,  subject  to  applicable  limitations.   Corporate
shareholders  should,  however,  consider  the effect of  Section  246(c) of the
Internal Revenue Code, which disallows the 70% dividends-received deduction with
respect  to  stock  that is held for  forty-five  (45)  days or  less.  For this
purpose,  the  length of time a  taxpayer  is  deemed to have held  stock may be
reduced by periods during which the taxpayer's  risk of loss with respect to the
stock is  diminished  by reason of the  existence  of  certain  options or other
transactions.  Moreover,  under Section 246A of the Internal  Revenue Code, if a
corporate  shareholder  has incurred  indebtedness  directly  attributable to an
investment in shares, the 70% dividends-received deduction may be reduced.

         In addition,  amounts received by a corporate  shareholder  pursuant to
the  Offer  to  Purchase  that are  treated  as a  dividend  may  constitute  an
"extraordinary  dividend"  under Section 1059 of the Internal  Revenue Code. The
"extraordinary   dividend"  rules  of  the  Internal  Revenue  Code  are  highly
complicated.  Accordingly,  any corporate shareholder that might have a dividend
as a result  of the sale of shares  pursuant  to the  Offer to  Purchase  should
review the  "extraordinary  dividend" rules to determine the  applicability  and
impact of such rules to it.

         Additional  Tax  Considerations.   The  distinction  between  long-term
capital gains and ordinary income is relevant because,  in general,  individuals
currently are subject to taxation at a reduced rate on their "net capital gain,"
which is the excess of net long-term  capital gains over net short-term  capital
losses,  for the  year.  Tax  rates on  long-term  capital  gain for  individual
shareholders vary depending on the  shareholders'  income and holding period for
the shares.  In  particular,  reduced tax rates apply to gains  recognized by an
individual  from the  sale of  capital  assets  held  for  more  than one  year,
currently 15 percent or less.

                                       24


         Shareholders are urged to consult their own tax advisors  regarding any
possible  impact on their  obligation to make estimated tax payments as a result
of the  recognition of any capital gain, or the receipt of any ordinary  income,
caused by the surrender of any shares to The Wilber Corporation  pursuant to the
Offer to Purchase.

         Foreign  Shareholders.  The Wilber  Corporation  will  withhold  United
States  federal income tax at a rate of 30% from gross proceeds paid pursuant to
the Offer to Purchase to a foreign shareholder or his agent, unless we determine
that a reduced rate of  withholding  is  applicable  pursuant to a tax treaty or
that an exemption from withholding is applicable  because the gross proceeds are
effectively  connected  with the  conduct of a trade or  business by the foreign
shareholder within the United States. For this purpose, a foreign shareholder is
any shareholder that is not (i) a citizen or resident of the United States, (ii)
a domestic  corporation or domestic  partnership,  (iii) an estate the income of
which from sources  without the United States is effectively  connected with the
conduct of a trade or business  within the United  States,  or (iv) a trust if a
court within the United States is able to exercise primary  supervision over the
administration  of the trust,  and one or more United  States  persons  have the
authority to control all substantial  decisions of the trust.  Without  definite
knowledge to the contrary,  we will determine whether a shareholder is a foreign
shareholder by reference to the shareholder's address. A foreign shareholder may
be  eligible  to file for a  refund  of the tax or a  portion  of the tax if the
shareholder    (a)   meets    the    "complete    redemption,"    "substantially
disproportionate" or "not essentially  equivalent to a dividend" tests described
above, (b) is entitled to a reduced rate of withholding pursuant to a treaty and
The Wilber  Corporation  withheld at a higher rate, or (c) is otherwise  able to
establish  that no tax or a reduced  amount of tax was due. In order to claim an
exemption  from  withholding  on the ground that gross proceeds paid pursuant to
the Offer to Purchase are  effectively  connected with the conduct of a trade or
business by a foreign  shareholder  within the United States or that the foreign
shareholder is entitled to the benefits of a tax treaty, the foreign shareholder
must deliver to the  Depositary,  or other  person who is otherwise  required to
withhold  United  States  tax,  a  properly  executed  statement  claiming  such
exemption or benefits.  These  statements  may be obtained from the  Depositary.
Foreign  shareholders are urged to consult their own tax advisors  regarding the
application  of  United  States  federal  income  tax   withholding,   including
eligibility  for a  withholding  tax  reduction  or  exemption  and  the  refund
procedures.

         Backup  Withholding.  See Section 3 with respect to the  application of
the United States federal income tax backup withholding.

         The tax discussion set forth above is included for general  information
only and may not apply to shares  acquired in  connection  with the  exercise of
stock  options or pursuant to other  compensation  arrangements  with The Wilber
Corporation.  The tax  consequences  of a sale pursuant to the Offer to Purchase
may vary depending upon, among other things, the particular circumstances of the
tendering  shareholder.  No  information  is provided with respect to the state,
local or foreign tax  consequences of the transaction  contemplated by the Offer
to  Purchase.  Shareholders  are  urged to  consult  their own tax  advisors  to
determine the particular  federal,  state, local and foreign tax consequences to
them of tendering shares pursuant to the Offer to Purchase and the effect of the
stock ownership attribution rules described above.

16.      EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENTS

         The  Wilber  Corporation  expressly  reserves  the  right,  in our sole
discretion,  to extend the period of time during  which the Offer to Purchase is
open by giving oral or written  notice of the  extension to the  Depositary  and
making  a public  announcement  of the  extension.  There  can be no  assurance,
however, that we will exercise our right to extend the Offer to Purchase. During
any extension,  all shares previously  tendered will remain subject to the Offer
to  Purchase,  except to the extent that shares may be withdrawn as set forth in
Section 4. We also expressly reserve the right, in our sole discretion,  to: (i)
terminate  the Offer to  Purchase  and not  accept  for  payment  any shares not
previously  accepted  for  payment  or,  subject to Rule  13e-4(f)(5)  under the
Exchange  Act which  requires us either to pay the  consideration  offered or to
return the shares  tendered  promptly after the termination or withdrawal of the
Offer to Purchase,  to postpone payment for shares upon the occurrence of any of
the conditions  specified in Section 7 hereof,  by giving oral or written notice
of the  termination to the Depositary  and making a public  announcement  of the
termination; and (ii) amend the Offer to Purchase in any respect. Any amendments
to the  Offer to  Purchase  will be  effected  by public  announcement.  Without
limiting  the manner in which The Wilber  Corporation  may choose to make public
announcement of any extension,  termination or amendment, The Wilber Corporation
shall have no  obligation,  except as otherwise  required by applicable  law, to
publish, advertise or otherwise communicate any public announcement,  other than
by making a release to PR Newswire,  except in the case of an announcement of an
extension of the Offer to Purchase,  in which case The Wilber  Corporation shall
have  no  obligation  to  publish,   advertise  or  otherwise   communicate  the
announcement other than by issuing a notice of the extension by press release or
other public announcement, which notice shall be issued no later than 9:00 a.m.,
New York City Time,  on the next  business  day after the  previously  scheduled
Expiration Date. Material changes to information  previously provided to holders
of the shares in this Offer to Purchase  or in  documents  furnished  subsequent
thereto  will be  disseminated  to  holders  of shares in  compliance  with Rule
13e-4(e)(3) promulgated by the SEC under the Exchange Act.

         If we  materially  change  the  terms of the Offer to  Purchase  or the
information  concerning  the  Offer  to  Purchase,  or if we  waive  a  material
condition of the Offer to Purchase,  we will extend the Offer to Purchase to the
extent required by Rules  13e-4(d)(2)  and  13e-4(e)(3)  under the Exchange Act.
Those rules  require that the minimum  period  during which an Offer to Purchase
must  remain  open  following  material  changes  in the  terms of the  Offer to
Purchase or information concerning the Offer to Purchase, other than a change in
price,  change in dealer's  soliciting fee or change in percentage of securities
sought,  will  depend on the facts and  circumstances,  including  the  relative
materiality of the terms or  information.  In a published  release,  the SEC has
stated that in its view,  an offer to purchase  should remain open for a minimum
of five  business  days from the date that notice of a material  change is first
published, sent or given. The Offer to Purchase will continue or be extended for
at least ten (10) business days from the time The Wilber Corporation  publishes,
sends or gives to  holders  of shares a notice  that we will:  (i)  increase  or
decrease  the  price  we  will  pay  for  shares  or the  amount  of the  dealer
manager's/information  agent's  soliciting fee; or (ii) increase,  except for an
increase not exceeding 2% of the outstanding  shares,  or decrease the number of
shares we seek.

The Wilber Corporation for its own account and for the accounts of its customers

connection with the Offer to Purchase.  The Depositary  will receive  reasonable
and  customary  compensation  for its services and will also be  reimbursed  for
certain out-of-pocket  expenses.  The Wilber Corporation has agreed to indemnify
Registrar and Transfer Company against  liabilities  arising from its good faith
performance of services as Depositary in connection  with the Offer to Purchase.

solicitations or recommendations in connection with the Offer to Purchase

         We will not pay any fees or commissions to any broker,  dealer or other
person for soliciting tenders of shares pursuant to the Offer to Purchase, other
than the fee of the dealer manager.  The Wilber  Corporation will, upon request,
reimburse brokers, dealers,  commercial banks and trust companies for reasonable
and  customary  handling  and mailing  expenses  incurred by them in  forwarding
materials relating to the Offer to Purchase to their customers.

expiration  of  the offer, other than shareholders who tender conditionally, and
for whom the condition is not satisfied. See sections 1, 2 and 6 of the Offer to
Purchase.  All  shares  not  purchased  pursuant  to the offer, including shares
tendered  at  prices  greater  than  the purchase price and shares not purchased
because  of  proration  or  because  they  were  conditionally  tendered and not
accepted  for  purchases  will  be returned to the tendering shareholders at The
Wilber Corporation's expense as promptly as practicable following the expiration
date. Wilber Corporation is not aware of any state where the making of the Offer
to  Purchase  is  prohibited  by administrative or judicial action pursuant to a
valid  state  statute. If we become aware of any valid state statute prohibiting
the  making of the Offer to Purchase, we will make a good faith effort to comply
with  the  statute.  If, after such good faith effort, we cannot comply with the
statute, the Offer to Purchase will not be made to, nor will tenders be accepted
from  or  on  behalf of, holders of shares in that state. In those jurisdictions
whose  securities,  blue  sky  or other laws require the Offer to Purchase to be
made by a licensed broker or dealer, the Offer to Purchase shall be deemed to be
made on behalf of The Wilber Corporation by the Dealer Manager/Information Agent
or  one  or  more registered brokers or dealers licensed under the laws of these
jurisdictions.

irrevocable.

      The undersigned  understands that tenders of shares pursuant to any one of
the  procedures  described in Section 2 or 3 of the Offer to Purchase and in the
instructions  to this Letter of Transmittal  will  constitute the  undersigned's
acceptance of the terms and conditions of the offer, including the undersigned's

validly tendered and not withdrawn pursuant to the offer taking into account the
number of shares so tendered and the prices specified by tendering stockholders.

number of shares as are validly tendered and not withdrawn at prices not greater
than  $11.40  nor  less  than  $9.90  per  share,  pursuant  to the  offer.  The

provisions,  and that The  Wilber  Corporation  will  return  all other  shares,
including  shares tendered and not withdrawn at prices greater than the purchase
price,   shares  not  purchased  because  of  proration  and  shares  that  were
conditionally  tendered  and not  accepted.  The  undersigned  understands  that
tenders of shares  pursuant to any one of the procedures  described in Section 2
or 3 of the  Offer  to  Purchase  and in the  instructions  to  this  Letter  of
Transmittal will constitute an agreement  between the undersigned and The Wilber
Corporation upon the terms and subject to the conditions of the offer.

      The undersigned  recognizes that, under certain circumstances set forth in
the Offer to Purchase,  The Wilber  Corporation may terminate or amend the offer
or may  postpone  the  acceptance  for payment of, or the  payment  for,  shares
tendered or may not be required to purchase any of the shares tendered hereby or

         The Wilber Corporation, a New York corporation, has appointed us to act

         The Wilber  Corporation  will determine the single per share price, not

below the purchase  price and not  withdrawn,  The Wilber  Corporation  will buy
shares (i) from shareholders who owned  beneficially as of the close of business
on March 17, 2006 and continue to own beneficially as of the expiration date, an
aggregate  of fewer than 100 shares who  properly  tender all their shares at or
below the purchase  price,  and (ii) then,  on a pro rata basis,  from all other

To Our Clients:

         Enclosed  for  your  consideration  are the  Offer to  Purchase  (white
booklet), dated April 4, 2006, and the related Letter of Transmittal (blue form)

of $11.40 nor less than $9.90 per share, as specified by tendering shareholders,
upon the terms and subject to the conditions set forth in the offer.

         The Wilber  Corporation  will determine the single per share price, not
in  excess  of  $11.40  nor less than  $9.90  per  share,  net to the  tendering
shareholder,  in cash, that it will pay for shares validly tendered  pursuant to
the offer,  taking into  account the number of shares so tendered and the prices
specified  by tendering  shareholders.  The Wilber  Corporation  will select the
lowest  purchase price that will allow it to buy 650,000  shares,  or the lesser
number of shares that are validly tendered at prices not in excess of $11.40 nor
less than $9.90 per share.  All shares  properly  tendered at prices at or below
the purchase  price and not  withdrawn on or prior to the  expiration  date,  as

who  tender  conditionally  and for whom the  condition  is not  satisfied.  See

         3.       The offer is not  conditioned  on any minimum number of shares
                  being tendered pursuant to the offer.

         4.       The offer,  proration period and withdrawal rights will expire
                  at 5:00 p.m.,  New York City Time, on May 4, 2006,  unless The
                  Wilber Corporation extends the offer.

         5.       The offer is for 650,000  shares,  constituting  approximately
                  5.8% of the shares outstanding as of March 17, 2006.

         6.       Tendering  shareholders  will  not be  obligated  to  pay  any
                  brokerage  commissions,  solicitation  fees,  or,  subject  to
                  instruction  7 of the Letter of  Transmittal,  stock  transfer
                  taxes on The Wilber Corporation's  purchase of shares pursuant
                  to the offer.

         7.       If you beneficially held, as of the close of business on March
                  17,  2006 an  aggregate  of  fewer  than  100  shares  and you
                  continue to beneficially  own as of the expiration date of the
                  offer an  aggregate  of fewer  than  100  shares,  and (i) you
                  instruct  us to tender on your  behalf  all your  shares at or
                  below the  purchase  price before the  expiration  date of the
                  offer and (ii)  complete the box  captioned  "Odd Lots" in the
                  enclosed  Instruction Form, then The Wilber Corporation,  upon
                  the terms and  subject to the  conditions  of the offer,  will
                  accept all your shares for purchase before proration,  if any,
                  of the purchase of other shares  validly  tendered at or below
                  the purchase price.

         8.       If you wish to tender  portions  of your  shares at  different
                  prices, you must complete a separate Instruction Form for each
                  price at which you wish to tender

                                       1


                  each portion of your shares.  We must submit separate  Letters
                  of  Transmittal on your behalf for each price you will accept.
                  You  cannot,  however,  tender  the same  shares at  different
                  prices.

         If you wish to have us  tender  any or all of your  shares,  please  so
instruct us by completing, executing, detaching and returning to us the enclosed
Instruction Form. An envelope to return your Instruction Form to us is enclosed.
If you authorize us to tender your shares, we will tender all your shares unless
you specify otherwise on the enclosed Instruction Form.

         Your instruction form should be forwarded to us in ample time to permit
us to submit a tender on your  behalf on or before  the  expiration  date of the
offer. The offer,  proration  period and withdrawal  rights expire at 5:00 p.m.,
New York City Time, on May 4, 2006, unless the company extends the offer.

         As  described  in  section  1 of the  Offer to  Purchase,  if more than
650,000  shares have been  validly  tendered at prices at or below the  purchase
price and not  withdrawn on or prior to the  expiration  date, as defined in the
Offer to Purchase, The Wilber Corporation will purchase properly tendered shares
on the basis set forth below:

               (a) first,  all shares  validly  tendered and not withdrawn on or
prior to the  expiration  date by or on  behalf  of any  shareholder  who  owned
beneficially, as of the close of business on March 17, 2006 and continues to own
beneficially  as of the  expiration  date, an aggregate of fewer than 100 shares
who:

                  (1)  validly  tenders all of the shares at a price at or below
         the purchase price - partial and  conditional  tenders will not qualify
         for this preference; and

                  (2) completes  the box  captioned  "Odd Lots" on the Letter of
         Transmittal; and

               (b) second,  after  purchase of all of the forgoing  shares,  all
shares validly tendered from other shareholders who properly tender their shares
at prices at or below the purchase price,  and who do not withdraw them prior to
the expiration of the offer,  other than shareholders who tender  conditionally,
and  for  whom  the  condition  is  not  satisfied,  on a pro  rata  basis  with
appropriate adjustments to avoid purchases of fractional shares, as described in
sections 1, 2 and 6 of the Offer to Purchase.

         You may condition  your tender on The Wilber  Corporation  purchasing a
minimum  number of your  tendered  shares.  In such case,  if as a result of the
proration  provisions  in the Offer to  Purchase  The Wilber  Corporation  would
purchase  less  than  the  minimum  number  of  your  shares,  then  The  Wilber
Corporation will not purchase any of your shares, except as provided in the next
sentence.  If so many  conditional  tenders would be deemed  withdrawn  that the
total number of shares to be purchased falls below 650,000  shares,  then to the
extent  feasible,  The Wilber  Corporation will select enough of the conditional
tenders  that  would  otherwise  have been so  withdrawn  to permit  The  Wilber
Corporation  to purchase  650,000  shares.  In selecting  among the  conditional
tenders,  The Wilber  Corporation will select by lot and will limit its purchase
in each case to the minimum number of shares designated. See sections 1 and 6 of
the Offer to Purchase.

                                       2


         The  offer  is  being  made  to  all  holders  of  shares.  The  Wilber
Corporation  is not aware of any  jurisdiction  where the making of the offer is
not in compliance with applicable law. If The Wilber  Corporation  becomes aware
of any jurisdiction  where the making of the offer is not in compliance with any
valid  applicable law, The Wilber  Corporation  will make a good faith effort to
comply  with the law.  If,  after a good faith  effort,  The Wilber  Corporation
cannot  comply with the law,  the offer will not be made to, nor will tenders be
accepted from or on behalf of, holders of shares residing in that  jurisdiction.
In any  jurisdiction  the securities or blue sky laws of which require the offer
to be made by a licensed broker or dealer, the offer is being made on The Wilber
Corporation's  behalf  by the  dealer  manager/information  agent or one or more
registered brokers or dealers licensed under the laws of that jurisdiction.

            GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                         NUMBER ON SUBSTITUTE FORM W-9


Guidelines for determining the proper identification number to give the Payer.

Social  Security  numbers  have  nine  digits  separated  by two  hyphens:  i.e.
000-00-0000.  Employer identification numbers have nine digits separated by only
one hyphen: i.e.  00-0000000.  The table below will help determine the number to
give the payer.


Purpose of Form

A person who is required to file an information return with the IRS, must obtain
your correct taxpayer identification number (TIN) to report, for example, income
paid to you, real estate transactions,  mortgage interest you paid,  acquisition
or abandonment of secured  property,  cancellation of debt, or contributions you
made to an IRA.

U.S.  person.  Use Form W-9 only if you are a U.S. person  (including a resident
alien),  to provide your correct TIN to the person requesting it (the requester)
and, when applicable, to:

         1.  Certify  that the TIN you are giving is correct (or you are waiting
for a number to be issued),

         2. Certify that you are not subject to backup withholding, or

         3. Claim  exemption from backup  withholding  if you are a U.S.  exempt
payee. In 3 above, if applicable, you are also certifying that as a U.S. person,
your allocable share of any partnership  income from a U.S. trade or business is
not subject to the  withholding  tax on foreign  partners'  share of effectively
connected income.

Note.  If a requester  gives you a form other than Form W-9 to request your TIN,
you must use the requester's  form if it is  substantially  similar to this Form
W-9.

For federal tax purposes, you are considered a person if you are:

o An individual who is a citizen or resident of the United States,

o A partnership,  corporation,  company,  or association created or organized in
the United States or under the laws of the United States, or

o Any estate (other than a foreign estate) or trust.  See  Regulations  sections
301.7701-6(a) and 7(a) for additional information.

Special rules for partnerships. Partnerships that conduct a trade or business in
the United States are generally required to pay a withholding tax on any foreign
partners' share of income from such business.  Further, in certain cases where a
Form W-9 has not been  received,  a  partnership  is required to presume  that a
partner is a foreign person, and pay the withholding tax. Therefore,  if you are
a U.S. person that is a partner in a partnership  conducting a trade or business
in the United States, provide Form W-9 to the partnership to establish your U.S.
status and avoid withholding on your share of partnership income.

The person who gives Form W-9 to the  partnership  for purposes of  establishing
its U.S.  status and avoiding  withholding on its allocable  share of net income
from the  partnership  conducting a trade or business in the United States is in
the following cases:

o The U.S. owner of a disregarded entity and not the entity,

o The U.S. grantor or other owner of a grantor trust and not the trust, and

o The U.S. trust (other than a grantor trust) and not the  beneficiaries  of the
trust.

Foreign person. If you are a foreign person,  do not use Form W-9. Instead,  use
the appropriate Form W-8 (see Publication 515, Withholding of Tax on Nonresident
Aliens and Foreign  Entities).  Nonresident  alien who becomes a resident alien.
Generally, only a nonresident alien individual may use the terms of a tax treaty
to reduce or eliminate  U.S. tax on certain types of income.  However,  most tax
treaties contain a provision known as a "saving clause." Exceptions specified in
the saving clause may permit an exemption from tax to continue for certain types
of income even after the recipient has otherwise  become a U.S.  resident  alien
for tax purposes.

         If you  are a  U.S.  resident  alien  who is  relying  on an  exception
contained in the saving  clause of a tax treaty to claim an exemption  from U.S.
tax on certain  types of income,  you must attach a  statement  to Form W-9 that
specifies the following five items:

         1. The treaty  country.  Generally,  this must be the same treaty under
which you claimed exemption from tax as a nonresident alien.

         2. The treaty article addressing the income.

         3. The article number (or location) in the tax treaty that contains the
saving  clause  and its  exceptions.  4. The  type and  amount  of  income  that
qualifies  for the  exemption  from tax.  5.  Sufficient  facts to  justify  the
exemption from tax under the terms of the treaty article.

Example. Article 20 of the U.S.-China income tax treaty allows an exemption from
tax for scholarship income received by a Chinese student  temporarily present in
the United States. Under U.S. law, this student will become a resident alien for
tax purposes if his or her stay in the United States  exceeds 5 calendar  years.
However, paragraph 2 of the first Protocol to the U.S.-China treaty (dated April
30,  1984) allows the  provisions  of Article 20 to continue to apply even after
the Chinese  student  becomes a resident alien of the United  States.  A Chinese
student  who  qualifies  for this  exception  (under  paragraph  2 of the  first
protocol) and is relying on this exception to claim an exemption from tax on his
or her  scholarship  or  fellowship  income would attach to Form W-9 a statement
that includes the information described above to support that exemption.

    If you are a  nonresident  alien or a foreign  entity not  subject to backup
withholding  give the  requester  the  appropriate  completed  Form W-8. What is
backup  withholding?  Persons making certain  payments to you must under certain
conditions  withhold and pay to the IRS 28% of such payments (after December 31,
2002).  This is called  "backup  withholding."  Payments  that may be subject to
backup  withholding  include  interest,  dividends,  broker and barter  exchange
transactions,  rents,  royalties,  nonemployee  pay, and certain  payments  from
fishing  boat  operators.  Real  estate  transactions  are not subject to backup
withholding.

You will not be subject to backup  withholding  on  payments  you receive if you
give the requester your correct TIN, make the proper certifications,  and report
all your taxable interest and dividends on your tax return. Payments you receive
will be subject to backup withholding if:

         1. You do not furnish your TIN to the requester,

         2.  You do not  certify  your  TIN  when  required  (see  the  Part  II
instructions on page 4 for details),

         3. The IRS tells the requester that you furnished an incorrect TIN,

         4. The IRS tells you that you are subject to backup withholding because
you did not report  all your  interest  and  dividends  on your tax return  (for
reportable interest and dividends only), or

         5. You do not  certify  to the  requester  that you are not  subject to
backup withholding under 4 above (for reportable  interest and dividend accounts
opened after 1983 only).

Certain payees and payments are exempt from backup withholding.

See the  instructions  below and the separate  Instructions for the Requester of
Form W-9.

Also see Special rules regarding partnerships on page 1.

Penalties

Failure to furnish  TIN. If you fail to furnish your correct TIN to a requester,
you are subject to a penalty of $50 for each such failure unless your failure is
due to  reasonable  cause and not to willful  neglect.  Civil  penalty for false
information  with respect to withholding.  If you make a false statement with no
reasonable  basis that  results in no backup  withholding,  you are subject to a
$500 penalty. Criminal penalty for falsifying information.  Willfully falsifying
certifications or affirmations may subject you to criminal  penalties  including
fines and/or imprisonment.

Misuse of TINs. If the requester  discloses or uses TINs in violation of federal
law,  the  requester  may be subject to civil and criminal  penalties.  Specific

Part I. Taxpayer Identification
Number (TIN)

Enter your TIN in the  appropriate  box. If you are a resident  alien and you do
not have and are not  eligible  to get an SSN,  your TIN is your IRS  individual
taxpayer  identification  number (ITIN).  Enter it in the social security number
box. If you do not have an ITIN, see How to get a TIN below.

         If you are a sole  proprietor and you have an EIN, you may enter either
your SSN or EIN. However, the IRS prefers that you use your SSN.

         If you are a single-owner LLC that is disregarded as an entity separate
from its owner (see Limited  liability  company (LLC) on page 2), enter your SSN
(or EIN, if you have one). If the LLC is a corporation, partnership, etc., enter
the entity's EIN.

Note.  See  the  chart  on page 4 for  further  clarification  of  name  and TIN
combinations.

How to get a TIN. If you do not have a TIN, apply for one immediately.  To apply
for an SSN, get Form SS-5,  Application  for a Social  Security Card,  from your
local  Social  Security  Administration  office  or  get  this  form  online  at
www.socialsecurity.gov.  You may also get this form by  calling  1-800-772-1213.
Use Form W-7, Application for IRS Individual Taxpayer  Identification Number, to
apply for an ITIN, or Form SS-4, Application for Employer Identification Number,
to apply  for an EIN.  You can  apply for an EIN  online  by  accessing  the IRS
website at  www.irs.gov/businesses  and  clicking on  Employer ID Numbers  under
Related  Topics.  You can  get  Forms  W-7 and  SS-4  from  the IRS by  visiting
www.irs.gov or by calling 1-800-TAX-FORM (1-800-829-3676).

         If you are  asked to  complete  Form  W-9 but do not have a TIN,  write
"Applied For" in the space for the TIN,  sign and date the form,  and give it to
the requester.  For interest and dividend  payments,  and certain  payments made
with respect to readily tradable instruments, generally you will have 60 days to
get a TIN  and  give  it to the  requester  before  you are  subject  to  backup
withholding  on  payments.  The  60-day  rule does not  apply to other  types of
payments.  You will be subject to backup  withholding on all such payments until
you provide your TIN to the requester.

Note.  Writing  "Applied  For" means that you have already  applied for a TIN or
that you intend to apply for one soon.  Caution:  A disregarded  domestic entity
that has a foreign owner must use the appropriate Form W-8.

Part II. Certification

To establish to the withholding  agent that you are a U.S.  person,  or resident
alien, sign Form W-9. You may be requested to sign by the withholding agent even
if items 1, 4, and 5 below indicate  otherwise.  For a joint  account,  only the
person  whose  TIN is  shown  in Part I  should  sign  (when  required).  Exempt
recipients, see Exempt From Backup Withholding on page 2.

Signature  requirements.  Complete the certification as indicated in 1 through 5
below.

         1. Interest,  dividend, and barter exchange accounts opened before 1984
and broker  accounts  considered  active during 1983. You must give your correct
TIN, but you do not have to sign the certification.

         2. Interest,  dividend,  broker,  and barter  exchange  accounts opened
after 1983 and broker  accounts  considered  inactive during 1983. You must sign
the certification or backup withholding will apply. If you are subject to backup
withholding and you are merely providing your correct TIN to the requester,  you
must cross out item 2 in the certification before signing the form.

         3. Real estate transactions.  You must sign the certification.  You may
cross out item 2 of the certification.

         4. Other payments.  You must give your correct TIN, but you do not have
to sign the certification unless you have been notified that you have previously

                                                              Exhibit (a)(2)(iv)

                             THE WILBER CORPORATION



                                  INSTRUCTIONS
              FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

         1. Guarantee of Signatures.  Except as otherwise  provided  below,  all
signatures on this Letter of Transmittal must be guaranteed by a firm that is an
eligible  institution because it is a member of a registered national securities
exchange or the  National  Association  of  Securities  Dealers,  Inc.,  or by a
commercial bank, a trust company, a savings bank, a savings and loan association
or a credit  union  which has  membership  in an  approved  signature  guarantee
medallion  program.  Signatures  on  this  Letter  of  Transmittal  need  not be
guaranteed  (i) if this  Letter  of  Transmittal  is  signed  by the  registered
holder(s)  of the shares,  which term,  for  purposes  of this  document,  shall
include any participant in the book-entry  transfer  facility whose name appears
on a security  position  listing as the owner of shares,  tendered  herewith and
such   holder(s)   have  not  completed  the  box  entitled   "Special   Payment
Instructions" or the box entitled "Special Delivery Instructions" on this Letter
of Transmittal or (ii) if the shares are tendered for the account of an eligible
institution. See instruction 6.

         2.  Delivery  of Letter  of  Transmittal  and  Shares.  This  Letter of
Transmittal or, in the case of a book-entry  transfer,  an agent's  message,  as
defined below, is to be used either if certificates are to be forwarded herewith
or if delivery of shares is to be made by  book-entry  transfer  pursuant to the
procedures set forth in Section 3 of the Offer to Purchase. Certificates for all
physically delivered shares, or a confirmation of a book-entry transfer into the
depositary's account at the book-entry transfer facility of all shares delivered
electronically,  as well as a properly  completed  and duly  executed  Letter of
Transmittal, or a manually signed copy thereof, and any other documents required
by this Letter of Transmittal, must be received by the depositary at the address
set forth on the front  page of this  Letter of  Transmittal  on or prior to the
expiration date, as defined in the Offer to Purchase. The term "agent's message"
means a message transmitted by the book-entry transfer facility to, and received
by, the  depositary  and forming a part of the  book-entry  confirmation,  which
states  that  the   book-entry   transfer   facility  has  received  an  express
acknowledgment   from  the  participant  in  the  book-entry  transfer  facility
tendering the shares,  that such participant has received and agrees to be bound
by the terms of this Letter of Transmittal  and that The Wilber  Corporation may
enforce the agreement against the participant.

         The  method  of  delivery  of  this   Letter  of   Transmittal,   share
certificates  and all other required  documents is at the option and risk of the
tendering  stockholder,  and  delivery  will be deemed  made only when  actually
received  by the  depositary.  If  certificates  for  shares  are  sent by mail,
registered mail with return receipt requested, properly insured, is recommended.

         Except as specifically permitted by Section 6 of the Offer to Purchase,
no  alternative  or  contingent  tenders will be accepted.  See Section 1 of the
Offer to  Purchase.  By  executing  this Letter of  Transmittal,  or a facsimile
thereof, the tendering stockholder waives any right to receive any notice of the
acceptance for payment of the shares.

         3. Inadequate  Space.  If the space provided herein is inadequate,  the
certificate  numbers  and/or the number of shares should be listed on a separate
signed schedule attached to this Letter of Transmittal.

         4.  Partial  Tenders;  Not  Applicable  to  Stockholders  Who Tender by
Book-Entry Transfer. If fewer than all the shares represented by any certificate
delivered to the  depositary  are to be  tendered,  fill in the number of shares
that are to be tendered in the box entitled "Number of Shares Tendered." In this
case, a new certificate  for the remainder of the shares  represented by the old
certificate  will be sent to the person(s)  signing this Letter of  Transmittal,
unless  otherwise  provided in the "Special  Payment  Instructions"  or "Special
Delivery  Instructions"  boxes on this  Letter of  Transmittal,  as  promptly as
practicable  following the expiration or  termination  of the offer.  All shares
represented by  certificates  delivered to the depositary will be deemed to have
been tendered unless otherwise indicated.



         5. Indication of Price at Which Shares are Being  Tendered.  For shares
to be validly  tendered,  the stockholder  must check the box indicating (i) the
price per share at which he or she is tendering shares under "Price (In Dollars)
Per Share at Which Shares Are Being Tendered" in this Letter of Transmittal,  or
(ii) that the person is tendering shares at the purchase price determined by The
Wilber  Corporation  pursuant to the terms of the offering  under this  heading.
Only one box may be  checked.  If more than one box is  checked  or if no box is
                               -------------------------------------------------
checked,  there is no valid tender of shares.  A  stockholder  wishing to tender
--------------------------------------------------------------------------------
portions  of his or her share  holdings  at  different  prices  must  complete a
--------------------------------------------------------------------------------
separate  Letter  of  Transmittal  for each  price at which he or she  wishes to
--------------------------------------------------------------------------------
tender each  portion of his or her shares.  The same shares  cannot be tendered,
-----------------------------------------
unless  previously  validly  withdrawn  as provided in Section 4 of the Offer to
Purchase, at more than one price.

         6. Signatures on Letter of Transmittal;  Stock Powers and Endorsements.
If this  Letter of  Transmittal  is signed by the  registered  holder(s)  of the
shares hereby,  the signature(s)  must correspond with the name(s) as written on
the face of the  certificates  without  alteration,  enlargement  or any  change
whatsoever.

         If any of the shares  hereby are held of record by two or more persons,
all persons must sign this Letter of Transmittal.

         If any of the shares  tendered hereby are registered in different names
on different certificates,  it will be necessary to complete, sign and submit as
many separate  letters of  transmittal as there are different  registrations  of
certificates.

         If this Letter of Transmittal is signed by the registered  holder(s) of
the shares  tendered  hereby,  no endorsements of certificates or separate stock
powers are required  unless  payment of the purchase  price is to be made to, or
shares not tendered or not  purchased  are to be  registered in the name of, any
person other than the registered holder(s).  Signatures on any such certificates
or stock powers must be guaranteed by an eligible  institution.  See instruction
1.

         If this  Letter of  Transmittal  is signed by a person  other  than the
registered holder(s) of the shares tendered hereby,  certificates evidencing the
shares  tendered  hereby must be endorsed or accompanied  by  appropriate  stock
powers,  in  either  case,  signed  exactly  as the  name(s)  of the  registered
holder(s) appear(s) on the certificates for the shares. Signature(s) on any such
certificates or stock powers must be guaranteed by an eligible institution.  See
instruction 1.

         If this  Letter of  Transmittal  or any  certificate  or stock power is
signed  by  a  trustee,  executor,  administrator,  guardian,  attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or representative
capacity,  the person  should so  indicate  when  signing,  and proper  evidence
satisfactory to The Wilber  Corporation of the authority of the person so to act
must be submitted.

         7. Stock Transfer Taxes. The Wilber Corporation will pay or cause to be
paid any stock  transfer  taxes  with  respect to the sale and  transfer  of any
shares to it or its order  pursuant to the offer.  If,  however,  payment of the
purchase  price is to be made to, or shares not tendered or not purchased are to
be registered in the name of, any person other than the registered holder(s), or
if  tendered  shares are  registered  in the name of any  person  other than the
person(s)  signing this Letter of Transmittal,  the amount of any stock transfer
taxes,  whether  imposed  on the  registered  holder(s),  the  other  person  or
otherwise,  payable on account of the  transfer  to the person  will be deducted
from the purchase price unless satisfactory evidence of the payment of taxes, or
exemption  therefrom,  is  submitted.  See  Section 5 of the Offer to  Purchase.
Except as  provided in this  instruction  7, it will not be  necessary  to affix
transfer tax stamps to the certificates representing shares tendered hereby.



         8.  Special  Payment and  Delivery  Instructions.  If the check for the
purchase  price of any shares  purchased is to be issued in the name of,  and/or
any shares not tendered or not  purchased  are to be returned to, a person other
than the person(s) signing this Letter of Transmittal or if the check and/or any
certificates  for  shares  not  tendered  or not  purchased  are to be mailed to
someone other than the  person(s)  signing this Letter of  Transmittal  or to an
address other than that shown above in the box captioned  "Description of Shares
Tendered,"  then the  boxes  captioned  "Special  Payment  Instructions"  and/or
"Special  Delivery  Instructions"  on  this  Letter  of  Transmittal  should  be
completed.  Stockholders  tendering shares by book-entry  transfer will have any
shares not accepted for payment returned by crediting the account  maintained by
the stockholder at the book-entry  transfer facility from which the transfer was
made.

         9. Odd Lots.  As described in the Offer to Purchase,  if fewer than all
shares  validly  tendered at or below the purchase price and not withdrawn on or
prior to the expiration  date are to be purchased,  the shares  purchased  first
will consist of all shares tendered by any stockholder who owned beneficially as
of the close of business on March 17, 2006, and continues to own beneficially as
of the  expiration  date,  an aggregate of fewer than 100 shares and who validly
and  unconditionally  tendered  all the shares at or below the  purchase  price,
including by not  designating a purchase  price as described  above.  Partial or
conditional  tenders  of  shares  will not  qualify  for this  preference.  This
preference  will not be available  unless the box  captioned  "Odd Lots" in this
Letter of Transmittal is completed.

         10.  Substitute  Form W-9 and Form W-8. The  tendering  stockholder  is
required to provide the depositary with either a correct taxpayer identification
number  on  Substitute  Form  W-9,  which  is  provided  under   "Important  Tax
Information"  below,  or a properly  completed Form W-8.  Failure to provide the
information on either  Substitute Form W-9 or Form W-8 may subject the tendering
stockholder to 28% federal  income tax backup  withholding on the payment of the
purchase  price.  The box in Part 2 of Substitute Form W-9 may be checked if the
tendering  stockholder has not been issued a taxpayer  identification number and
has applied for a number or intends to apply for a number in the near future. If
the box in Part 2 is checked and the  depositary is not provided with a taxpayer
identification  number by the time of payment,  the depositary will withhold 28%
on all payments of the purchase price thereafter until a taxpayer identification
number is provided to the depositary.

         11.  Requests for  Assistance  or Additional  Copies.  Any questions or
requests for assistance may be directed to the dealer  manager/information agent
at their telephone number and address listed in the Offer to Purchase.  Requests
for  additional  copies of the Offer to Purchase,  this Letter of Transmittal or
other tender offer  materials may be directed to the dealer  manager/information
agent and copies will be furnished promptly at The Wilber Corporation's expense.
Stockholders  may also contact their local broker,  dealer,  commercial  bank or
trust company for assistance concerning the offer.

         12. Irregularities. All questions as to the purchase price, the form of
documents,  and  the  validity,  eligibility,  including  time of  receipt,  and
acceptance of any tender of shares will be determined by The Wilber Corporation,
in its sole discretion,  and its determination  shall be final and binding.  The
Wilber  Corporation  reserves the absolute right to reject any or all tenders of
shares that it determines  are not in proper form or the  acceptance for payment
of or payment for shares  that may,  in the opinion of The Wilber  Corporation's
counsel, be unlawful. Except as otherwise provided in the Offer to Purchase, The
Wilber  Corporation  also  reserves  the  absolute  right  to  waive  any of the
conditions  to the offer or any defect or  irregularity  in any tender of shares
and The Wilber  Corporation's  interpretation of the terms and conditions of the
offer, including these instructions,  shall be final and binding. Unless waived,
any defects or  irregularities  in connection  with tenders must be cured within
such  time  as The  Wilber  Corporation  shall  determine.  None  of The  Wilber
Corporation,  the dealer manager/information agent, the depositary, or any other
person shall be under any duty to give notice of any defect or  irregularity  in
tenders,  nor shall any of them incur any liability for failure to give any such
notice.  Tenders  will not be deemed to have been  made  until all  defects  and
irregularities have been cured or waived.



         IMPORTANT:  THIS  LETTER OF  TRANSMITTAL,  OR A  MANUALLY  SIGNED  COPY
THEREOF,  TOGETHER WITH CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY  TRANSFER AND
ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY THE DEPOSITARY,  ON OR PRIOR TO
THE EXPIRATION DATE.

IMPORTANT TAX INFORMATION

         Under federal income tax law, a stockholder  whose tendered  shares are
accepted for payment is required to provide the depositary,  as payer,  with the
stockholder's  correct taxpayer  identification number on Substitute Form W-9 on
the  reverse  side  of the  Letter  of  Transmittal.  If the  stockholder  is an
individual,  the taxpayer  identification  number is his or her social  security
number.  For  businesses  and  other  entities,   the  number  is  the  employer
identification  number.  If the  depositary  is not  provided  with the  correct
taxpayer  identification  number or properly completed  Substitute Form W-9, the
stockholder  may be subject to a $50  penalty  imposed by the  Internal  Revenue
Service. In addition, payments that are made to such stockholder with respect to
shares  purchased  pursuant  to the offer may be subject to backup  withholding.
Certain  stockholders,  including,  among others,  all  corporations and certain
foreign  individuals and entities,  are not subject to these backup  withholding
and reporting  requirements.  In order for a noncorporate foreign stockholder to
qualify as an exempt  recipient,  that stockholder must complete and sign a Form
W-8,  Certificate  of Foreign  Status,  attesting to that  stockholder's  exempt
status. The Form W-8 can be obtained from the depositary.  Exempt  stockholders,
other than  noncorporate  foreign  stockholders,  should  furnish their taxpayer
identification  number,  write "Exempt" on the face of the  Substitute  Form W-9
below and sign, date and return the Substitute  Form W-9 to the depositary.  See
the enclosed Guidelines for Certification of Taxpayer  Identification  Number on
Substitute Form W-9 (green form) for additional instructions.

         If federal  income tax backup  withholding  applies,  the depositary is
required  to  withhold  28% of any  payments  made  to the  stockholder.  Backup
withholding is not an additional tax.  Rather,  the federal income tax liability
of persons  subject to backup  withholding  will be reduced by the amount of the
tax withheld. If withholding results in an overpayment of taxes, a refund may be
obtained.

PURPOSE OF SUBSTITUTE FORM W-9 AND FORM W-8

         To avoid backup  withholding on payments that are made to a stockholder
with  respect to shares  purchased  pursuant to the offer,  the  stockholder  is
required to notify the depositary of his or her correct taxpayer  identification
number  by  completing  the  Substitute  Form W-9  included  in this  Letter  of
Transmittal  certifying  that the  taxpayer  identification  number  provided on
Substitute  Form  W-9 is  correct  and  that  (i) the  stockholder  has not been
notified by the  Internal  Revenue  Service that he or she is subject to federal
income tax backup  withholding  as a result of failure to report all interest or
dividends or (ii) the Internal Revenue Service has notified the stockholder that
he or she is no longer subject to federal income tax backup withholding. Foreign
stockholders  must  submit a properly  completed  Form W-8 in order to avoid the
applicable backup withholding;  provided,  however, that backup withholding will
not  apply  to  foreign  stockholders  subject  to 30%,  or lower  treaty  rate,
withholding on gross  payments  received  pursuant to the offer.

WHAT NUMBER TO GIVE THE DEPOSITARY

         The  stockholder is required to give the depositary the social security
number or employer  identification number of the registered owner of the shares.
If the  shares  are in more  than one name or are not in the name of the  actual
owner,   consult  the  enclosed   Guidelines  for   Certification   of  Taxpayer
Identification  Number  on  Substitute  Form W-9  (green  form)  for  additional
guidance on which number to report.


                                                               Exhibit (a)(2)(v)

                            THE WILBER CORPORATION

April 4, 2006


Dear Shareholders of The Wilber Corporation:

         Over  time,  The  Wilber  Corporation's   profitable   operations  have
contributed  to the  growth  of a  capital  base  that  exceeds  all  applicable
regulatory  standards  and the amount of capital  needed to support  our banking
business.  After  evaluating  a variety of  alternatives  to utilize this strong
capital base more effectively and to maximize value to our shareholders, we have
determined that a repurchase of our own shares at this time would be in the best
interests of our shareholders.  The board of directors has approved a repurchase
of  650,000  shares of The Wilber  Corporation's  common  stock,  or 5.8% of our
11,145,937  outstanding  shares.  A copy of the Offer to Purchase dated April 4,
2006 is enclosed.

         We are  conducting  the offer  through  a  procedure  referred  to as a
"Modified Dutch Auction." This procedure allows you to select the price at which
you are willing to sell,  or tender,  all or part of your shares  within a price
range of not more than $11.40 per share and not less than $9.90 per share.  Upon
expiration  of the offer,  we will select the lowest  purchase  price from those
shares tendered that will allow us to buy 650,000 shares.  All shares  purchased
in the offer will receive the same  purchase  price,  even those shares that are
tendered below the purchase price. In addition,  if you own less than 100 shares
and tender all of your shares at or below the purchase  price,  you will receive
priority and have all of your shares  purchased even if more than 650,000 shares
are tendered.  No brokerage  fees or  commissions  will be charged to you if you
tender your shares.

         We encourage  each  shareholder to read carefully the Offer to Purchase
and related materials. Neither The Wilber Corporation nor our board of directors
has made any  recommendation  whether  to  tender  shares  to us and we have not
authorized any person to make such recommendation. You should make your decision
independently after consulting with your advisors.

         To  assist  us with  this  offer,  we have  engaged  Sandler  O'Neill &
Partners,   L.P.  to  serve  as  our  dealer  manager  and  information   agent.
Representatives  from Sandler  O'Neill may contact you by phone to make sure you
have  received  the Offer to Purchase  and related  materials  and to answer any
questions you may have. If you need information or additional forms, please call
Sandler O'Neill toll free at (800) 635-6851.

         Unless otherwise extended, the offer will expire at 5:00 p.m., New York
City Time, on May 4, 2006. We again encourage you to read carefully the enclosed
material.



         As always, we appreciate your interest in The Wilber Corporation.

                                                     Sincerely,

                                                     /s/ Douglas C. Gulotty

================================================================================
                             THE WILBER CORPORATION
                        ANNOUNCES MODIFIED DUTCH AUCTION
              TO PURCHASE UP TO 650,000 SHARES OF OUTSTANDING STOCK

                              FOR IMMEDIATE RELEASE
================================================================================
Oneonta, New York

DATE:    April 4, 2006
FROM:    Douglas C. Gulotty, President and CEO
PHONE:   607-433-4172


         ONEONTA,  NEW YORK: The Wilber Corporation ("GIW")(Amex(R)), the parent
company  of  Wilber National Bank, today announced that it intends to repurchase
up  to 650,000 shares, or approximately 5.8%, of its 11,145,937 shares of common
stock  currently  outstanding,  through  a  modified Dutch auction issuer tender
offer.

         Under the Modified  Dutch Auction  format,  shareholders  will have the
opportunity  to sell  part or all of their  shares  to the  Company  at the cash
purchase price selected by the  shareholder of not less than $9.90 per share nor
greater than $11.40 per share.  Upon  expiration of the offer,  the Company will
select the lowest  purchase  price that will permit it to buy the desired number
of shares.  All shares  purchased  will be purchased at the same price,  even if
tendered at a lower price.  If more than the maximum  number of shares sought is
tendered at or below the price,  tendering  shareholders  owning  fewer than 100
shares will have their shares purchased without pro-ration and other shares will
be  purchased  pro rata.  Shareholders  of record will,  in general,  be able to
tender their shares free of all brokerage  commissions and stock transfer taxes,
if any, which will be paid by Wilber.  The offer is not conditioned on a minimum
number of shares being  tendered.  Wilber will pay for the shares  purchased and
for all related fees and expenses out of available  funds and cash on hand.  The
offer to purchase  shares will begin on April 4, 2006 and expire on May 4, 2006,
unless  extended.  Shares  tendered  into the offer may be withdrawn at any time
before the  expiration  date of the offer.  On March 17, 2006,  the closing sale
price for the Company's common stock as reported on the Amex(R) was $10.00.

         Commenting  on the tender  offer,  Douglas C.  Gulotty,  the  Company's
President and Chief Executive Officer said: "Over time, The Wilber Corporation's
profitable  operations  have  contributed  to the growth of a capital  base that
exceeds all applicable  regulatory standards and the amount of capital needed to
support our banking  business.  After  evaluating a variety of  alternatives  to
utilize this strong capital base more  effectively  and to maximize value to our
shareholders,  we have  determined  that a repurchase  of our own shares at this
time would be in the best interests of our shareholders."

                                                            Exhibit (a)(2)(viii)


         This announcement is neither an offer to purchase nor a solicitation of
an offer to sell  shares.  The offer is made  solely  by the offer to  purchase,
dated April 4, 2006, and the related letters of transmittal,  and any amendments
or supplements  thereto. The tender offer is not being made to, nor will tenders
be accepted from or on behalf of, holders of shares in any jurisdiction in which
the making or  acceptance  of offers to sell shares  would not be in  compliance
with the laws of that  jurisdiction.  In any jurisdiction  where the securities,
blue sky or other laws require the tender offer to be made by a licensed  broker
or dealer,  the tender  offer shall be deemed to be made on behalf of The Wilber
Corporation  by  Sandler  O'Neill &  Partners,  L.P.,  the  dealer  manager  and
information agent for the tender offer, or by one or more registered  brokers or
dealers licensed under the laws of that jurisdiction.

                     NOTICE OF OFFER TO PURCHASE FOR CASH BY

                             THE WILBER CORPORATION

        UP TO 650,000 SHARES OF ITS COMMON STOCK, AT A PURCHASE PRICE NOT
               GREATER THAN $11.40 NOR LESS THAN $9.90 PER SHARE

         The Wilber Corporation,  a New York corporation ("Wilber"), is offering
to purchase for cash up to 650,000 shares of its common stock ("Common  Stock"),
par value  $0.01 per share,  upon the terms and  subject to the  conditions  set
forth in the offer to  purchase,  dated April 4, 2006 (the "Offer to  Purchase")
and the  accompanying  letter of transmittal (the "Letter of  Transmittal"),  as
each may be amended and supplemented  from time to time.  Wilber is inviting its
stockholders  to  tender  their  shares  at prices  specified  by the  tendering
stockholder  that are not greater than $11.40 nor less than $9.90 per share, net
to the  seller in cash,  without  interest,  upon the terms and  subject  to the
conditions of the tender offer.

         THE TENDER  OFFER IS SUBJECT  TO  CERTAIN  CONDITIONS  SET FORTH IN THE
OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL.

         THE TENDER OFFER, PRORATION PERIOD AND WITHDRAWAL RIGHTS WILL EXPIRE AT
5:00 P.M.,  NEW YORK CITY TIME, ON TUESDAY,  MAY 4, 2006,  UNLESS WILBER EXTENDS
THE TENDER OFFER.

         THE BOARD OF  DIRECTORS  OF  WILBER  HAS  APPROVED  THE  TENDER  OFFER.
HOWEVER,  NEITHER WILBER NOR ITS BOARD OF DIRECTORS IS MAKING ANY RECOMMENDATION
TO ITS  STOCKHOLDERS  AS TO WHETHER TO TENDER OR REFRAIN  FROM  TENDERING  THEIR
SHARES OR AS TO THE PRICE OR PRICES AT WHICH  STOCKHOLDERS  MAY CHOOSE TO TENDER
THEIR SHARES. STOCKHOLDERS MUST MAKE THEIR OWN DECISIONS AS TO WHETHER TO TENDER
THEIR  SHARES  AND,  IF SO, HOW MANY SHARES TO TENDER AND THE PRICE OR PRICES AT
WHICH THEY SHOULD TENDER THEIR  SHARES.  IN SO DOING,  STOCKHOLDERS  SHOULD READ
CAREFULLY THE  INFORMATION IN THE OFFER TO PURCHASE AND IN THE RELATED LETTER OF
TRANSMITTAL, INCLUDING WILBER'S REASONS FOR MAKING THE TENDER OFFER.

         Based upon the number of shares  tendered  and the prices  specified by
the tendering stockholders, Wilber will determine, upon the terms and subject to
the conditions of the tender offer, the lowest single price within the $11.40 to
$9.90  range that will allow it to buy  650,000  shares of Common  Stock or such
fewer  number of shares of Common  Stock as are  properly  tendered  within that
price range and not properly withdrawn. Wilber will purchase all shares

                                       1


properly tendered,  and not properly  withdrawn,  prior to the "expiration date"
(as defined below) at the relevant purchase price, upon the terms and subject to
the  conditions  of the tender  offer  including  the "odd lot,"  proration  and
conditional tender provisions described in the Offer to Purchase.

         Wilber will not pay any interest on the purchase  price for the shares,
regardless  of any delay in making  payment.  Wilber will  acquire all shares of
Common  Stock  acquired  in the  tender  offer at the  relevant  purchase  price
regardless  of  whether  the  stockholder  selected  a  lower  price.  The  term
"expiration  date" means 5:00 p.m.,  New York City time,  on  Tuesday,  April 4,
2006, unless and until Wilber,  in its sole discretion,  shall have extended the
period of time during which the tender  offer will remain  open,  in which event
the term "expiration  date" shall refer to the latest time and date at which the
tender offer, as so extended by Wilber, shall expire. Wilber reserves the right,
in its sole  discretion,  to purchase  more than 650,000  shares of Common Stock
pursuant to the tender offer, as described in the Offer to Purchase, and subject
to applicable law.

         For  purposes  of the  tender  offer,  Wilber  will be  deemed  to have
accepted for payment, and therefore purchased, shares properly tendered (and not
properly withdrawn) at or below the relevant purchase price,  subject to the odd
lot, proration and conditional tender provisions of the tender offer, only when,
as and if Wilber gives oral or written notice to Registrar and Transfer Company,
the  depositary for the tender offer (the  "Depositary"),  of its acceptance for
payment of shares  under the tender  offer.  Wilber will make payment for shares
tendered  and  accepted  for payment  under the tender  offer only after  timely
receipt  by  the  Depositary  of  certificates  for  such  shares  or of  timely
confirmation  of a  book-entry  transfer of such  shares  into the  Depositary's
account  at the  "book-entry  transfer  facility"  (as  defined  in the Offer to
Purchase),  a properly  completed and duly executed  Letter of  Transmittal or a
manually signed facsimile  thereof or in the case of a book-entry  transfer,  an
"agent's message" (as defined in the Offer to Purchase), and any other documents
required by the Letter of Transmittal.

         Upon the terms and subject to the  conditions of the tender  offer,  if
more than  650,000  shares of Common Stock have been  properly  tendered and not
properly  withdrawn  prior to the  expiration  date at  prices  at or below  the
applicable purchase price, Wilber will purchase properly tendered shares of each
class on the following basis:

         - First,  from all  holders  of "odd  lots"  (holders  of less than 100
shares of Common  Stock) who  properly  tender all their  shares at or below the
purchase price  selected by Wilber and do not properly  withdraw them before the
expiration  date  (partial  and  conditional  tenders  will not qualify for this
preference);

         - Second, on a pro rata basis from all other  stockholders who properly
tender shares at or below the applicable  purchase price selected by Wilber with
respect to such shares,  other than  stockholders who tender  conditionally  and
whose conditions are not satisfied; and

         Wilber will return all other tendered  shares that it has not purchased
promptly after the expiration date.

         Wilber expressly reserves the right, in its sole discretion,  to extend
the period of time  during  which the  tender  offer is open and  thereby  delay
acceptance for payment of, and payment for, any shares of Common Stock by giving
oral or written  notice of such  extension to the Depositary and making a public
announcement  thereof no later than 9:00 a.m.,  New York City time,  on the next
business day after the last previously  scheduled or announced  expiration date.

                                       2


During any such extension,  all shares of Common Stock  previously  tendered and
not properly  withdrawn will remain subject to the tender offer and to the right
of a tendering stockholder to withdraw such stockholder's shares.

         Wilber's  management and Board of Directors have  thoroughly  evaluated
Wilber's   operations,   financial  condition,   capital  needs,   strategy  and
expectations  for the future and believe  that the tender offer is a prudent use
of its financial  resources,  given its business profile and strategic plan, and
that  investing  in its  own  shares  is an  attractive  use of  capital  and an
efficient  means to provide value to its  stockholders.  Wilber believes that it
has  adequate  sources  of  capital  to  complete  the share  repurchase,  while
operating  its business  and pursuing  strategic  opportunities.  Following  the
purchase  of the  shares,  Wilber  believes  that funds  provided  by  earnings,
combined  with other sources of  liquidity,  will be fully  adequate to meet its
funding  needs  for the  foreseeable  future.  Upon  completion  of the Offer to
Purchase,  Wilber  expects  that  it and its  wholly  owned  subsidiary,  Wilber
National  Bank,  will  continue  to  maintain  the  highest  regulatory  capital
standards. The tender offer represents the opportunity for Wilber to return cash
to  stockholders  who elect to tender  their shares of Common Stock at a premium
over the recent  trading  prices for the shares  without  the usual  transaction
costs  associated  with open  market  sales,  while at the same time  increasing
non-tendering  stockholders'  proportionate  interest  in  Wilber  and  thus  in
Wilber's  future  earnings  and  assets at no  additional  cost to them.  Wilber
believes  the  tender  offer,  if  completed,  will be  accretive  to  currently
projected earnings per share, although there can be no assurance of this.

         Generally,  a  stockholder  will  be  subject  to U.S.  federal  income
taxation  when the  stockholder  receives  cash from Wilber in exchange  for the
shares that the stockholder tenders.

         Tenders of shares under the tender offer are  irrevocable,  except that
such  shares  may be  withdrawn  at any time prior to the  expiration  date and,
unless  previously  accepted for payment by Wilber under the tender  offer,  may
also be  withdrawn  at any time after  12:00  Midnight,  New York City time,  on
Wednesday,  May 31, 2006.  For such  withdrawal to be effective,  the Depositary
must timely receive a written,  telegraphic or facsimile  transmission notice of
withdrawal  at its  address  set  forth on the back  cover  page of the Offer to
Purchase.  Stockholders who have submitted  multiple Letters of Transmittal with
respect  to  tenders  at  different  prices  must  submit  separate  notices  of
withdrawal corresponding to each such Letter of Transmittal previously submitted
in order to properly  withdraw their shares.  Any such notice of withdrawal must
specify  the name of the  tendering  stockholder,  the  number  of  shares to be
withdrawn and the name of the registered holder of such shares.

         If the  certificates  for shares to be withdrawn have been delivered or
otherwise  identified  to the  Depositary,  then,  before  the  release  of such
certificates,  the  certificate  numbers  shown  on  such  certificates  must be
submitted to the  Depositary  and the  signature(s)  on the notice of withdrawal
must be guaranteed  by an "eligible  guarantor  institution"  (as defined in the
Offer to Purchase),  unless such shares have been tendered for the account of an
eligible  guarantor  institution.  If shares have been tendered  pursuant to the
procedure for book-entry transfer set forth in the Offer to Purchase, any notice
of  withdrawal  also must  specify the name and the number of the account at the
book-entry  transfer  facility to be credited with the withdrawn shares and must
otherwise comply with such book-entry transfer facility's procedures.

         Wilber will determine, in its sole discretion,  all questions as to the
form and validity of any notice of  withdrawal,  including  the time of receipt,
and such determination will be final and

                                       3


binding.  None of Wilber,  Registrar and Transfer  Company,  as the  Depositary,
Sandler O'Neill & Partners,  L.P., as the information  agent/dealer  manager, or
any other person will be under any duty to give  notification  of any defects or
irregularities  in any tender or notice of withdrawal or incur any liability for
failure to give any such notification.

         The information  required to be disclosed by Rule 13e-4(d)(1) under the
Securities  Exchange  Act of 1934,  as  amended,  is  contained  in the Offer to
Purchase and is incorporated herein by reference.

         Wilber is mailing promptly the Offer to Purchase and the related Letter
of  Transmittal  to record  holders of shares  whose  names  appear on  Wilber's
stockholder  list and will furnish the Offer to Purchase and the related  Letter
of  Transmittal  to brokers,  dealers,  commercial  banks,  trust  companies and
similar  persons  whose  names,  or the names of whose  nominees,  appear on the
stockholder list or, if applicable, who are listed as participants in a clearing
agency's  security  position  listing for  subsequent  transmittal to beneficial
owners of shares.

transfer and deliver such property to Trustee,  and trustee hereby  acknowledges
the receipt of such property, IN TRUST, to hold, manage, invest and reinvest, to
collect the income  therefrom and to distribute  the net income and principal in
accordance with the terms of this Agreement.

      I. DURING MY LIFETIME.

         A.  Discretionary  Payments for My Benefit.  Whenever  Trustee deems it
             --------------------------------------
necessary or advisable during my lifetime, Trustee may pay so much of the income
from  the  trust  and so much of the  principal  thereof  as  may,  in its  sole
discretion,  be necessary or advisable  for my support,  my health or my comfort
including,  but not limited to,  payment of income,  gift and real estate taxes,
insurance  premiums,  expenses  of medical  care,  expenses  of  protecting  and
maintaining  one  or  more  residences,   expenses  of  independent  contractors
providing services to or for my benefit, and wages of employees.

         B. Annual  Distribution.  Upon the  distribution  date in each calendar
            --------------------
year after 2003,  Trustee  shall  distribute  the balance of the trust  property
(excluding ten dollars  ($10.00)) to met. The distribution date for a particular
calendar year shall be the later of: (a) the date that is ninety (90) days after
the last addition to the trust occurring



in the calendar year immediately  prior to the particular  calendar year, or (b)
March 1st of the particular  calendar year.  Trustee is not restricted as to the
form or type of assets that must be distributed pursuant to this section.

         II. PAYMENTS AT MY DEATH. Upon my death, this trust shall terminate and
Trustee shall  distribute  all them  remaining  trust assets to: (a) a revocable
trust  which  is  named  as  the  residuary  beneficiary  of my  Will  if I have
established   such  a  trust  prior  to  my  death,   or  (b)  to  the  personal
representative of my estate if no such trust is in existence at my death.

      III. TRUSTEE'S COMPENSATION

         A.  Reasonable  Compensation.  Trustee  shall be  entitled  to  receive
             ------------------------
reasonable  compensation for its services  hereunder (which may be taken without
judicial authorization at the time or times permitted under law) and as shall be
agreed to with me. During my lifetime,  annual commissions may be charged wholly
to principal or wholly to income or partly to principal  and partly to income in
the discretion of Trustee.

         B.  Reimbursement  of  Expenses.   Trustee  shall  be  entitled  to  be
             ---------------------------
reimbursed for all expenses  reasonably  incurred by it in the administration of
the trust,  including  legal fees,  the fees of  investment  advisors  and other
similar expenses.

      IV. TRUST  IRREVOCABLE.  The trust hereby  created is  irrevocable,  and I
waive  all  right,  power  and  authority  to alter,  amend,  modify,  revoke or
terminate this Agreement.

      V. SUCCESSOR TRUSTEE.

         A.  Trustee  Resignation.  Any  Trustee  may  resign  at any time by an
             --------------------
acknowledged  instrument delivered to me and to any Trustee appointed to succeed
hereunder.

         B.  Appointment  of  Successor  Trustee.  Whenever  there is no  acting
             -----------------------------------
Trustee, my son, B. RICHARD WRIGHT, shall appoint a successor Trustee other than


                                       2


the Settlor or Settlor's spouse. The successor Trustee shall have all the powers
given the  originally  named Trustee.  No successor  Trustee shall be personally
liable  for  any  act or  omission  or any  predecessor.  The  appointment  of a
Successor  Trustee  shall be in writing  signed in the presence of two witnesses
and notarized.

         C.  Provisions  relating  to WILBER  NATIONAL  BANK.  In the event that
             -----------------------------------------------
Wilber National Bank (Trustee) is no longer owned by The Wilber Corporation,  or
there shall be any merger or consolidation  of The Wilber  Corporation or Wilber
National Bank in which The Wilber Corporation or Wilber National Bank is not the
continuing  or  surviving  corporation,   or  the  stockholders  of  The  Wilber
Corporation  or  Wilber  National  Bank  approve  any plan or  proposal  for the
liquidation or dissolution  of the Wilber  Corporation or Wilber  National Bank,
then,  in that event,  the  Settlor's  son, B. RICHARD  WRIGHT  shall  appoint a
successor Trustee other than Settlor or Settlor's spouse.

      VI. GENERAL PROVISIONS AND FIDUCIARY POWERS.

         A.  Investment  Counsel.  The  Trustee may employ  investment  counsel;
             -------------------
consult  with such  counsel on any  matters  relating  to the  retention,  sale,
purchase,  investment,  or reinvestment of securities or other property; and pay
such investment counsel reasonable  compensation for its services in addition to
the regular compensation of Trustee. Trustee may act upon or refrain from acting
upon the advice of such investment counsel in whole or in part.

         B.  Powers. Trustee shall hold, manage,  care for and protect the trust
             ------
property  and  shall  have the  following  powers  and  those  now or  hereafter
conferred by law:

            1. To retain any property  (including stock of any corporate Trustee
hereunder or a parent,  affiliate,  subsidiary  or  successor  of any  corporate
Trustee)  originally  constituting  the  trust  or  subsequently  added  hereto,
although not of a type, quality or  diversification  considered proper for trust
investments; the Settlor


                                       3


specifically relieves Trustee from any liability for loss or diminution of value
for  retaining or failing to diversify  any shares of stock  transferred  to the
Trustee  during the  Settlor's  lifetime,  regardless  of the  existence  of any
statute requiring such diversification by a fiduciary;

            2. To invest  and  reinvest  the  trust  property  in bonds,  stocks
(including  stocks or bonds of any  corporate  trustee  hereunder or a parent or
affiliate company), mortgages, bank deposits, options, future contracts, general
partnership interests,  limited partnership interests, limited liability company
interests, shares of registered investment companies, notes or other property of
any kind,  domestic or foreign,  suitable  for the  investment  of trust  funds,
including any  participation in any common trust fund; to deposit or arrange for
the deposit of securities in a central depository;

            3. To  cause  any  property  belonging  to the  trust  to be held or
registered  in Trustee's  name or in the name of a nominee or in such other form
as Trustee deems best without disclosing the trust relationship;

            4. To vote in person or by general or limited proxy, or refrain from
voting, any corporate securities  (including securities of any corporate trustee
hereunder or a parent or affiliate company) for any purpose; to exercise or sell
any subscription or conversion  rights;  to consent to and join in or oppose any
voting  trusts,   reorganizations,   consolidations,   merger,  foreclosure  and
liquidations  and in connection  therewith to deposit  securities and accept and
hold other property received therefore;

            5. To borrow  money from any  lender,  extend or renew any  existing
indebtedness and pledge any property in the trust;

            6. To sell at public or  private  sale,  contract  to sell,  convey,
exchange,   transfer  and  otherwise  deal  with  the  trust  property  and  any
reinvestments


                                       4


thereof,  and to sell put and covered call  options,  from time to time for such
price and upon such terms as Trustee seems fit;

            7. To employ  agents,  attorneys and proxies and to delegate to them
such powers as Trustee considers desirable;

            8. To compromise,  contest,  prosecute or abandon claims in favor of
or against the trust;

            9. To distribute  income and principal in cash or in kind, or partly
in each;

            10. To determine in cases not covered by statute the  allocation  of
receipts and disbursements between income and principal;

            11. To buy, sell and trade in  securities  of any nature,  including
short sales on margin and, for such  purposes,  may maintain and operate  margin
accounts  with brokers and may pledge any  securities  held or purchased by them
with such brokers as security for loans and advances made to Trustee;

            12. To perform other acts necessary or appropriate  for the property
administration of the trust, execute and deliver necessary  instruments and give
full receipts, and discharges; and

            13.  Notwithstanding  the  foregoing  provisions  of  this  section,
Trustee  shall not  purchase,  acquire,  accept or  otherwise  receive  any real
property in this trust.

         C.  Accounts.  Trustee  shall  render an  account of its  receipts  and
             --------
disbursements  and a  statement  of  assets  to me  within  ninety  days  of the
distribution date.

         D.  Administration  of Trust  Independent of Court. No trustee wherever
             ----------------------------------------------
acting  shall be required to give bond or surety or be  appointed  by or account
for the administration of any trust to any court. No statute with respect to


                                       5


underproductive property shall apply to any trust under this trust instrument. I
recommend that trust registration be neither voluntarily accomplished by Trustee
nor requested by any beneficiary.

         E.  Reduction  or Release of  Powers.  Trustee  shall have the power to
             --------------------------------
release or renounce any power, privilege, or right (including this power) or the
power to reduce the scope and extent of any power, privilege or right (including
this power). If there is more than one trustee acting hereunder,  this power may
be  exercised  by  any  one  trustee,  individually,  or  by  all  the  trustee,
collectively.

         F.  Trustee's  Certificate.  A certificate  signed by any trustee under
             ----------------------
this instrument and acknowledged by such trustee before a notary public shall be
conclusive evidence upon all persons and for all purposes of the facts stated in
the certificate  respecting the terms of this instrument and the identity of the
trustees who from time to time are serving under it.

         G.  Construction.  All  article  and  section  headings  used  are  for
             ------------
convenience only and shall not be resorted to for  interpretation of this trust.
Wherever the context so requires, the masculine, feminine or neuter gender shall
include the other two  genders,  the singular  shall  include the plural and the
plural shall include the singular.

         H. In creating  this trust,  I intend for the trust and the  intangible
personal property comprising the trust property not to be subject to Florida tax
on  intangible  personal  property,  and for the trust to qualify  under section
12C-2.0063 of the Florida Administrative Code. Accordingly, this Agreement shall
be  interpreted,  managed,  invested,  administered  and in all  other  respects
governed consistent with my intent.

         I.  Governing  Law. All aspects of this trust,  including  such trust's
             --------------
validity,  construction,  and administration shall be governed by the law of the
State of Flordia.


                                       6


         J. Additions.  I may transfer or assign additional  property to Trustee
            ---------
to be held under this  instrument,  subject to the  approval and  acceptance  by
Trustee.

         K. Discretionary Trust Termination. Whenever, in the sole discretion of
            -------------------------------
Trustee,  the  purposes  for which the  trust was  established  can no longer be
effectively  carried out because of a change in the law  affecting the trust and
its beneficiaries or any other changes in circumstances which makes continuation
of the trust  unwarranted,  Trustee  may  terminate  such  trust.  In such event
Trustee shall distribute the then remaining assets of the trust to me.

      VII.  ACCEPTANCE.  Trustee  accepts  the trust and agrees to  perform  its
duties hereunder.

      IN WITNESS WHEREOF, I have signed this Irrevocable Trust Agreement.
