      These proxy materials are being provided in connection with the
solicitation by the Board of Directors of Atlantic BancGroup, Inc. ("Atlantic
BancGroup") of proxies to be voted at the 2004 Annual Meeting of Shareholders,
and any adjournment thereof ("Annual Meeting"). Atlantic BancGroup's Annual
Report, which includes the financial statements for the fiscal year ended
December 31, 2003, accompanies this Proxy Statement, which is first being mailed
to shareholders on or about March 19, 2004.

Date, Time and Location

      >>    Thursday, April 22, 2004

Solicitation and Voting of Proxies

      This Proxy Statement and the accompanying Proxy Card are being furnished
to Atlantic BancGroup shareholders in connection with the solicitation of
proxies by the Board of Directors of Atlantic BancGroup, the parent holding
company of Oceanside Bank ("Bank"). Proxies obtained by the Board of Directors
will be voted at Atlantic BancGroup's Annual Meeting in the manner indicated by
the Board's recommendations stated in this Proxy Statement.

      Regardless of the number of shares of common stock that you own, it is
important that your shares be represented by proxy or that you be present at the
Annual Meeting. To vote by proxy, please indicate your vote in the spaces
indicated on the enclosed Proxy Card and return it signed and dated, in the
enclosed postage-paid envelope. Proxies obtained by the Board of Directors will
be voted in accordance with the directions given therein. If you do not indicate
how your shares should be voted on a matter, the shares represented by your
properly completed proxy will be voted as the Board of Directors recommends.

      In order for us to have a quorum present to be able to convene the Annual
Meeting, it is important that your proxy be returned promptly. Therefore,
whether or not you plan to be present at the Annual Meeting, please complete,
sign and date the enclosed Proxy Card and return it in the enclosed postage-paid
envelope, so that your proxy can be counted for purposes of establishing a
quorum in order that the Annual Meeting can proceed as scheduled.

Revocation of Proxy

      Your presence at the Annual Meeting will not automatically revoke your
proxy. However, you may revoke a proxy at any time prior to its exercise by:

      >>    Delivering a written notice of revocation to Atlantic BancGroup; or
      >>    Delivering a duly executed proxy bearing a later date to Atlantic
            BancGroup; or,
      >>    Attending the Annual Meeting and choosing to vote in person.

Voting Procedures

      Our Articles of Incorporation do not provide for cumulative voting. Under
the Florida Business Corporation Act ("Act"), directors are elected by a
plurality of the votes cast at a meeting at which a quorum is present. Our
Bylaws provide that a majority of shares entitled to vote and represented in
person or by proxy at a shareholder meeting constitutes a quorum. Therefore,
each shareholder of record on the record date has the right to vote, in person
or by proxy, the number of shares owned by him or her for as many director
nominees as there are directors to be elected. For example, if you own five
shares, you may vote a maximum of five shares for each director to be elected.

      Other matters are approved if affirmative votes cast for a proposal exceed
the votes cast against that proposal at a meeting at which a quorum is present,
unless a greater number of affirmative votes or voting by classes is required by
the Act or our Articles of Incorporation. Abstentions and broker non-votes have
no effect under the Act.

      If your shares are held in "street name," under certain circumstances your
brokerage firm may vote your shares. Brokerage firms have authority to vote
their customers' shares on certain "routine" matters, including the election of
directors. When a brokerage firm votes its customers' shares on routine matters,
these shares are also counted for purposes of establishing a quorum to conduct
business at the meeting. A brokerage firm cannot vote its customers' shares on
non-routine matters. Accordingly, these shares are not counted as votes against
a non-routine matter, but rather are not counted at all for these matters. There
are no non-routine matters to vote upon at this Annual Meeting.

      The close of business on February 27, 2004, has been fixed by the Board of
Directors as the "record date" for determination of shareholders entitled to
notice of, and to vote at, the Annual Meeting, and any adjournment thereof. On
the record date, there were 1,247,516 shares of Atlantic BancGroup common stock
outstanding which were held by approximately 650 shareholders.

                               MARKET INFORMATION

      Our common stock is quoted on the NASDAQ SmallCap Market under the symbol
"ATBC". Our primary market maker in the stock is Advest, Inc. The market price
for our stock is included in our Annual Report on Form 10-KSB under the heading
"Market Price for Registrant's Common Equity and Related Stockholder Matters."

                          BOARD OF DIRECTORS MEETINGS

      During the year ended December 31, 2003, Atlantic BancGroup's Board of
Directors held four regular and two special meetings. All directors attended at
least 75% of the total meetings of the Board of Directors and any committees on
which he or she served, except Mr. Dubberly, who attended 70% and Messrs.
Cervone and Wolfson, who each attended 67%. Atlantic BancGroup currently does
not pay directors' fees. The Directors of the Bank receive $750 for each Board
meeting. Members of the Loan Committee receive $250 per month for serving on the
Committee.

                      COMMITTEES OF THE BOARD OF DIRECTORS

General

      Atlantic BancGroup does not have a standing Nominating or Compensation
Committee. The Board of Directors acts as a Nominating Committee for the annual
selection of nominees for the election of directors. While the Board of
Directors will consider nominees recommended by shareholders, it has not
actively solicited such recommendations nor has it to date established any
director nominee criteria or shareholder nominee procedures. The Board of
Directors is reviewing the requirements of new Securities and Exchange
Commission rules to determine if a Nominating Committee should be established
and to set forth Atlantic BancGroup's position regarding shareholder
nominations.

      In 2003, Atlantic BancGroup had only one standing committee, the Audit
Committee, which was comprised of the same members that serve on the Bank's
Audit Committee. Atlantic BancGroup's Audit Committee met four times during the
year. The standing committees of the Bank are the: Audit Committee, Loan
Committee, Asset/Liability/Investment Committee, and Compensation Committee. The
following table lists the members of each Committee in 2003.

                          REPORT OF THE AUDIT COMMITTEE

      The audit functions of the Audit Committee are focused on three areas:

      o     The adequacy of Atlantic BancGroup's and the Bank's internal
            controls and financial reporting process and the reliability of
            Atlantic BancGroup's and the Bank's financial statements.

      o     The performance of Atlantic BancGroup's and the Bank's internal
            auditors and the independence and performance of Atlantic
            BancGroup's and the Bank's independent auditors.

      o     Atlantic BancGroup's and the Bank's compliance with legal and
            regulatory requirements.

      The Audit Committee met with management periodically to consider the
adequacy of Atlantic BancGroup's and the Bank's internal controls and the
objectivity of their financial reporting. These matters were discussed with
Atlantic BancGroup's and the Bank's independent auditors.

      The Audit Committee met with the independent auditors without management
present. The independent auditors have unrestricted access to the members of the
Audit Committee. The Audit Committee also recommends to the Board the
appointment of the independent auditors and periodically reviews their
performance, fees and independence from management.

      The Board of Directors has determined that none of the members of the
Audit Committee has a relationship to Atlantic BancGroup or the Bank that may
interfere with their independence from Atlantic BancGroup or the Bank and their
management.

      Ms. Robin Scheiderman, a Certified Public Accountant, with extensive
auditing experience, has the requisite financial expertise to qualify as an
"audit committee financial expert" as defined by Securities and Exchange
Commission Rules. Accordingly, the Board has designated her to hold that
position.

      Management has primary responsibility for Atlantic BancGroup's and the
Bank's financial statements and the overall reporting process, including the
system of internal controls. The independent auditors audit the annual financial
statements prepared by management, express an opinion as to whether those
financial statements fairly present the financial position, results of
operations and cash flows of Atlantic BancGroup and the Bank in conformity with
accounting principles generally accepted in the United States of America and
discuss with the Audit Committee any issues they believe should be raised or
addressed. The Audit Committee monitors these processes, relying without
independent verification, on the information provided to the Audit Committee and
on the representations made by management and the independent auditors.

      This year, the Audit Committee reviewed Atlantic BancGroup's and the
Bank's audited financial statements as of, and for, the fiscal year ended
December 31, 2003, and met with both management and independent auditors of
Atlantic BancGroup and the Bank to discuss those

           1315 South Third Street o Jacksonville Beach, Florida 32250


                                       4


financial statements. Management has represented to the Audit Committee that the
financial statements were prepared in accordance with accounting principles
generally accepted in the United States of America.

      The Audit Committee has received from, and discussed with, Stevens, Powell
& Company, P.A. the written disclosure and the letter required by Independence
Standards Board Standard No. 1 (Independence Discussions with Audit Committees).
These items relate to that firm's independence from Atlantic BancGroup and the
Bank. The Audit Committee also discussed with Stevens, Powell & Company, P.A.
any matters required to be discussed by Statement on Auditing Standards No. 61
(Communication with Audit Committees).

      Based on these reviews and discussions, the Audit Committee recommended to
the Board of Directors that Atlantic BancGroup's audited financial statements be
included in Atlantic BancGroup's and the Bank's annual report on Form 10-KSB for
the fiscal year ended December 31, 2003. The Audit Committee met four times in
2003. No Audit Committee member attended less than 75% of the meetings.

      Robin H. Scheiderman                       Donald F. Glisson, Jr.

Asset/Liability/Investment Committee

      The Asset/Liability/Investment Committee at the Bank establishes the asset
and liability management policies of the Bank, monitors and sets limitations for
interest-rate risk and reviews asset and liability reports relating to Atlantic
BancGroup's balance sheet mix. The Committee met four times during the year. No
member of the Asset/Liability/Investment Committee attended less than 75% of
Committee meetings.

Loan Committee

      The Loan Committee of the Bank meets as required to act upon significant
loan requests made to the Bank. The Committee met 29 times during the year. No
Loan Committee member attended less than 75% of Committee meetings, except Mr.
Wolfson who attended 72% of the meetings.

Compensation Committee

      The Bank's Compensation Committee meets as required to consider the
adequacy of the Bank's compensation policies in meeting the goals of the Bank.
The Compensation Committee met once in 2003, with all members in attendance.

                        PROPOSAL I. ELECTION OF DIRECTORS

      The Board of Directors is presently comprised of eight members. Atlantic
BancGroup's Articles of Incorporation provide that directors shall be divided
into three classes, which each serve for staggered three-year terms. This year,
Class II directors are to be elected. To the best of our knowledge, no director
nominee is being proposed for election pursuant to any agreement between that
person and any other person.

      The three nominees, Donald F. Glisson, Jr., Robin H. Scheiderman and
Gordon K. Watson named herein, have indicated that they are willing to stand for
election and to serve as directors if elected. Should a director nominee become
unable or unwilling to serve, proxies will be voted for the election of such
other person as the Board of Directors may choose to nominate.

      The affirmative vote of a plurality of the votes cast at the Annual
Meeting is needed to elect a director. Abstentions and withheld votes will have
the same effect as votes against a director nominee.

      Information relating to the business experience and age of Atlantic
BancGroup's director nominees, continuing directors and non-director executive
officers is set forth below.

               PROPOSAL II. RATIFICATION OF THE APPOINTMENT OF THE
                 INDEPENDENT AUDITOR FOR THE FISCAL YEAR ENDING
                                DECEMBER 31, 2004

      Following consultation with the Audit Committee, the Board of Directors
intends to retain the accounting firm of Stevens, Powell & Company, P.A.
("Stevens, Powell"), as the independent auditors for Atlantic BancGroup and the
Bank for the fiscal year ending December 31, 2004. A representative from the
firm is expected to be present at the Annual Meeting to make a statement and to
respond to shareholder questions.

      Audit Fees: The aggregate fees billed for professional services by
Stevens, Powell, in connection with the audit of the annual financial statements
and the reviews of the financial statements included in Atlantic BancGroup's
quarterly filings with the Securities and Exchange Commission for the fiscal
years ended December 31, 2002, and December 31, 2003, were $70,717 and $89,870,
respectively.

      Audit-Related Fees: In 2002 and 2003, Stevens, Powell also billed Atlantic
BancGroup $542 and $412, respectively for fees reasonably related to the
performance of its audit and reviews of financial statements. Such fees included
travel and postage and courier related fees.

      Tax Fees: In 2002 and 2003, Stevens, Powell also billed Atlantic BancGroup
$7,443 and $4,160, respectively for tax compliance and advice, including the
preparation of Atlantic BancGroup's corporate tax returns.

      All Other Fees: In addition to those fees described above, Stevens, Powell
also billed Atlantic BancGroup $1,900 and $1,000 in 2002 and 2003, respectively.
Such fees were for consultation related to branch profitability, director fees,
and budget analysis for 2002 and attendance at strategic planning session and
related consultation for 2003.

      In all instances, Stevens, Powell performance of those services was
pre-approved by Atlantic BancGroup's Audit Committee, except for the category of
All Other Fees, which is less than 5% of the total fees, and in 2003 was
directly related to an invitation to attend a meeting of Atlantic BancGroup's
Board of Directors.

      In order to be adopted, this item must be approved by the holders of a
majority of the outstanding shares of Atlantic BancGroup's common stock present
or represented by proxy and entitled to vote at the Annual Meeting. If the
shareholders do not vote in favor of the appointment of Stevens, Powell, the
Board of Directors will consider the selection of other auditors.
