Company Shares represented by such certificates, any certificate(s) for ABC
Common Stock issuable to me.

     3.   I acknowledge that for each share of Company Common Stock I own I will
receive consideration payable in shares of ABC Common Stock according to the

                (ALSO COMPLETE SUBSTITUTE FORM W-9 ON NEXT PAGE)

                           IMPORTANT TAX INFORMATION

               PLEASE COMPLETE AND SIGN IF YOU ARE AN INDIVIDUAL
                    SUBJECT TO THESE REPORTING REQUIREMENTS

     Under federal income tax law, a holder of Company Shares must provide ABC
with such holder's correct taxpayer identification number on Substitute Form W-9
set forth below.  If such holder is an individual, the taxpayer identification
number is his or her Social Security number.  If the Exchange Agent is not
provided with the correct taxpayer identification number, the holder of
surrendered Company Shares may be subject to a $50 penalty imposed by the
Internal Revenue Service.

     Certain holders of Company Shares (including, among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements.  In order for a foreign individual to
qualify as an exempt recipient, that holder of Company Shares must submit a
statement (Form W-8), signed under penalties of perjury, attesting to that
individual's exempt status.  Such Form W-8 can be obtained form ABC.

     If backup withholding applies, ABC is required to withhold 31% of any
payments made to the holder of previously outstanding Company Shares.  Backup
withholding is not an additional tax.  Rather, the tax liability of persons
subject to backup withholding will be reduced by the amount of tax withheld.  If
withholding results in an overpayment of taxes, a refund may be obtained.

Purpose of Substitute Form W-9.

     To prevent backup withholding on payments that are made to a holder of
Company Shares with respect to Company Shares surrendered, the holder of Company
Shares is required to notify ABC of his or her correct taxpayer identification
number by completing the form below certifying that the taxpayer identification
number provided on Substitute Form W-9 is correct (or that such holder of
Company Shares is awaiting a taxpayer identification number).

What Number to Give the Exchange Agent.

     The holder of Company Shares is required to give ABC the Social Security
Number or Employer Identification Number of the record owner of the Company
Shares.  If the Company 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 for additional guidance on
which number to report.

Privacy Act Notice -- Section 6109 requires most recipients of dividend,
interest, or other payments to give taxpayer identification numbers to payers
who must report the payments to IRS. IRS uses the numbers for identification
purposes. Payers must be given the numbers whether or not recipients are
required to file tax returns. Beginning January 1, 1984, payers must generally
withhold 20% of taxable interest, dividend, and certain other payments to a
payee who does not furnish a taxpayer identification number to a payer. Certain
penalties may also apply.
                                                     
Penalties                                            
(1) Penalty for Failure to Furnish Taxpayer Identification Number --If you fail
to furnish your taxpayer identification number to a payer, 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.
(2) Failure to Report Certain Dividend and Interest Payments -- If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an under-
payment attributable to that failure unless there is clear and convincing
evidence to the contrary.
(3) Civil Penalty for False Information with Respect to Withholding -- If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
(4) Criminal Penalty for Falsifying Information --Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.

                                  ABC BANCORP


TO IRWIN BANKCORP, INC. SHAREHOLDERS:

     Irwin Bankcorp, Inc. (the "Company") has mailed a Proxy
Statement/Prospectus dated July 31, 1997 (the "Proxy Statement"), to each
Company shareholder. The Proxy Statement describes the proposed merger (the
"Merger") of the Company with and into ABC Bancorp ("ABC") to be voted upon by
the Company shareholders at the Special Meeting to be held August 29, 1997. The
Merger, if approved by the Company shareholders at the Special Meeting, is
expected to be consummated as soon as practicable following the Special Meeting.
In accordance with the terms of the Agreement and Plan of Merger dated as of May
15, 1997, between the Company and ABC (the "Merger Agreement"), upon the
completion of all conditions under the Merger Agreement and the filing of
appropriate articles of merger in the office of the Georgia Secretary of State
(the "Effective Time"), each share of the common stock of the Company
outstanding immediately prior to the consummation of the Merger (the "Company
Shares"), other than shares held by shareholders who dissent from the Merger,
will be converted into the right to receive that number of whole shares of the
common stock, $1.00 par value per share, of ABC ("ABC Common Stock") having a
value equal to (i) 500,000, divided by (ii) the aggregate number of then-
outstanding Irwin Shares (the "Exchange Ratio"). The Exchange Ratio is subject
to adjustment (i) in the event of certain changes in the number of outstanding
shares of ABC Common Stock or (ii) upon the exercise, prior to the Effective
Time, of certain options to purchase Irwin Shares. Cash will be paid in lieu of
issuing fractional shares of ABC Common Stock.

     Questions and requests for information, additional copies of the Letter of
Transmittal or assistance relating to the Letter of Transmittal should be

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

particular denominations, explicit written instructions to the Exchange Agent
should be provided.

     11.  Lost Certificates.  If any of your certificates representing Company
          -----------------

Form W-9, which is in the Letter of Transmittal, and to indicate that such
holder is not subject to backup withholding by checking the box in Part 2 of the
form.  Failure to provide the information on the form may subject the
shareholder to 31% backup withholding on the cash consideration paid.  The box
on the form may be checked if the holder of Company Shares has not been issued a
TIN and has applied for a number or intends to apply for a number in the near
future.  If the box is checked and ABC is not provided with a TIN within 60
days, ABC will withhold 31% of the consideration paid thereafter until the TIN
is provided to ABC.

     13.  Failure to Consummate the Merger.  If the Merger Agreement is
          --------------------------------

soon as practicable to the persons submitting them.

          ---------------------------                                           
to have the same voting rights to which they were previously entitled, and the
right to receive all dividends paid on Company Shares deposited by them with the
Exchange Agent, until such time as the Merger becomes effective.

     15.  Construction.  All questions with respect to the Letter of Transmittal
          ------------                                                          
will be determined by the Company, which determination shall be final and
binding.  With the consent of the Company, the Exchange Agent may (but is not
required to) waive any material defects or variances in the manner in which the
Letter of Transmittal has been completed and submitted so long as the intent of
the holder of Company Shares submitting the Letter of Transmittal is reasonably
clear.
