and any adjournment  thereof ("Annual  Meeting").  Atlantic  BancGroup's  Annual
Report,  which  includes  the  financial  statements  for the fiscal  year ended

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").

      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  in  accordance  with  the  Board  of
Directors' recommenda-tions as stated in this Proxy Statement.

      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. How-ever, 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 on these types of matters 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 28, 2005, 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, 2004,  Atlantic  BancGroup's  Board of
Directors held four regular 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.  Atlantic  BancGroup  currently does not pay directors' fees, except for
$500 per month paid to its Chairman, Donald J. Glisson, Jr. The Directors of the
Bank receive $750 for each Board  meeting.  Members of the Bank's Loan Committee
receive $250 per month for serving on the Committee. Atlantic BancGroup requires
its Directors to attend the Annual Meeting of Shareholders,  and in 2004, all of
our Directors were in attendance.

                      COMMITTEES OF THE BOARD OF DIRECTORS

General

      Atlantic  BancGroup  does not have a standing  Nominating or  Compensation
Committee.  The Board of Directors as a whole acts as a Nominating Committee for
the annual  selection  of  nominees  for the  election  of  directors.  Atlantic
BancGroup does not feel a Nominating Committee is necessary because the Board as
a whole is very familiar with the community and is  knowledgeable  regarding the
selection  of  directors  from the  community.  In  addition,  other  than Barry
Chandler,  our  Chief  Executive  Officer  and  President,   our  directors  are
considered  "Independent Directors" under the National Association of Securities
Dealers Rules.  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 does not have a charter or other written  guidelines  for
the nominating process,  but the Board has historically  selected nominees based
on  their  activity  in the  community,  their  experience  with  other  banking
institutions and involvement with Oceanside Bank.

      In 2004,  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.  The Audit Committee has adopted a formal  charter,  a copy of
which is attached to this Proxy Statement as Exhibit A. 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 2004.

                          REPORT OF THE AUDIT COMMITTEE

      The 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  believes  that the members of the Audit  Committee
are all  "Independent  Directors" as defined under the National  Association  of
Securities Dealers Rules. In addition, the Board has determined that none of the
Directors  have  any  relationships   which  would  impair  their  abilities  to
objectively and impartially execute their duties.

      Ms. Robin  Scheiderman,  a Certified  Public  Accountant,  with  extensive
auditing  experi-ence,  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 Ms. Scheiderman 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  and express an opinion as to whether  those
financial  statements fairly present the financial position,  review the 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, 2004,  and met with both  management  and  independent  auditors of
Atlantic  BancGroup  and  the  Bank  to  discuss  those  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, 2004.  Atlantic  BancGroup's  and the Bank's
Audit Committee each met four times in 2004. 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,  except for Frank J. Cervone,  who attended
50% of the 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 35 times during the year. No
Loan Committee member attended less than 75% of Committee 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 2004, with all members in attendance.

                      o PROPOSAL I. ELECTION OF DIRECTORS o

      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, with each group serving for staggered three-year terms. This
year,  Class I 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,  Frank J.  Cervone,  Barry W.  Chandler  and Jimmy D.
Dubberly  have  indicated  that their  willingness  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.

      As previously discussed in this Proxy Statement, 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.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      Certain directors,  executive officers and principal shareholders (defined
as individuals owning 5% or more of Atlantic BancGroup common stock) of Atlantic
BancGroup are customers of, and have banking  relations  with,  the Bank.  Loans
made to these  individuals are governed under the provisions of Section 22(h) of
the Federal Reserve Act.  Section 22(h) requires that any loans made by the Bank
to such individuals,  or to any related interest of such individuals,  must: (i)
be on substantially the same terms, including interest rates and collateral,  as
those  prevailing at the time for comparable  transactions  with  non-affiliated
parties and;  (ii) not involve more than the normal risk of repayment or present
other unfavorable features.  These restrictions do not affect preferential loans
to full-time  employees who are not directors or executive  officers of Atlantic
BancGroup  or the  Bank.  Atlantic  BancGroup  has no loans  outstanding  to its
directors or officers.  As of December  31, 2004,  the Bank's total  outstanding
balances on loans to directors, executive officers and principal shareholders of
Atlantic BancGroup and the Bank were $1,964,102.37.

like services.

               PROPOSAL II. RATIFICATION OF THE APPOINTMENT OF THE

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, 2003, and December 31, 2004, were $89,870 and $110,850,
respectively.

      Audit-Related Fees: In 2003 and 2004, Stevens, Powell also billed Atlantic
BancGroup  $412 and  $465,  respectively,  for fees  reasonably  related  to the

      All Other Fees: In addition to those fees described above, Stevens, Powell
also billed Atlantic BancGroup $1,000 and $4,255 in 2003 and 2004, respectively.
For 2003,  such fees were for  attendance  at a strategic  planning  session and

2005, consultation for Federal Reserve reporting requirements, capital planning,
and  amendments  to  indexed  retirement  plan  and  other  accounting  matters,

pre-approved by Atlantic  BancGroup's Audit Committee,  pursuant to its internal
policies,  except for the  category of All Other Fees,  which is less than 5% of
the total fees, and in 2004 was directly related to either invitations to attend
meetings of Atlantic  BancGroup's Board of Directors (and/or follow-up  meetings
related to implementation of Section 404 of the  Sarbanes-Oxley Act in 2005) and
requests  of  management  of  the  Atlantic   BancGroup  to  provide  accounting
consultation or training.
