                                 PROXY STATEMENT

         These  proxy  materials  are  being  provided  in  connection  with the
solicitation  of proxies by the Board of Directors of Atlantic  BancGroup,  Inc.
("Atlantic  BancGroup") to be voted at the 2006 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, 2005, accompanies this Proxy Statement, which is first being mailed
to shareholders on or about March 24, 2006.

Date, Time and Location

         > Thursday, April 27, 2006
         > 3:00 p.m. local time

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' recommendations 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 for the Annual Meeting to 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.

         The close of business on February 28, 2006, 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." 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, 2005, 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  and  members  of the
Asset/Liability and Audit Committees receive $50 per meeting. Atlantic BancGroup
requires its  Directors  to attend the Annual  Meeting of  Shareholders,  and in
2005, all of our Directors were in attendance.

                      COMMITTEES OF THE BOARD OF DIRECTORS

         In 2005,  Atlantic BancGroup had three standing  committees,  the Audit
Committee,  the Nominating Committee and the Compensation  Committee.  The Audit
Committee has adopted a formal charter, a copy of which was attached to the 2005
Proxy Statement as Exhibit A.

         The  Nominating  Committee  meets to evaluate  director  candidates for
Atlantic  BancGroup's  Board of Directors.  This Committee has not yet adopted a
charter and does not have  written  procedures  or a policy on the  selection of
nominees or the evaluation of shareholder  recommendations.  Until a charter and
nominating  procedures  are put in  place,  the  Committee  will  make  all such
decisions  on a  case-by-case  basis,  in which it may  consider  the  nominee's
business background, involvement in the community, prior banking experience, and
involvement  with Oceanside Bank. These are the same criteria used in evaluating
candidates  selected  by the  Board.  Based  on  Atlantic  BancGroup's  size and
marketing  area, the Board believes these policies are  appropriate for Atlantic
BancGroup.  The  Committee  met one time in 2005;  each  director  attended that
meeting.  The  Nominating  Committee is composed of Chairman  Donald F. Glisson,
Jr., Frank J. Cervone, Jimmy D. Dubberly, and Gordon K. Watson.

         The  Compensation  Committee  serves  with regard to  compensation  and
personnel policies,  programs and plans,  including  management  development and
succession,  and to approve  employee  compensation  and benefit  programs.  The
Compensation  Committee does not have a charter. The Compensation  Committee met
one time in 2005. In 2005,  all members  attended  such  meeting.  The Board has
determined that each member of the Committee is independent as defined by Nasdaq
rules.  The  Compensation  Committee is composed of Chairman  Donald F. Glisson,
Jr., Frank J. Cervone, Jimmy D. Dubberly, and Gordon K. Watson.

                          REPORT OF THE AUDIT COMMITTEE

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

         |_|      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.

         |_|      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.

         |_|      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  also 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
Audit  Committee  members  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, 2005, and met with both management and the 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 the  accounting  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 the
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, 2005. Atlantic BancGroup's and the Bank's
Audit Committee each met three times in 2005. No Audit Committee member attended
less than 75% of the meetings,  other than Donald F. Glisson,  Jr., who attended
67%.

                    |_| 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,  with each group serving for  staggered  three-year
terms. This year, two Class III 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 two  nominees,  Conrad  L.  Williams  and  Dennis M.  Wolfson  have
indicated  their  willingness to stand for election and to serve as directors if
elected.  Should either  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 that are not performing according
to the terms of such  loans.  As of  December  31,  2005,  the Bank's  aggregate
outstanding  balances on loans to directors,  executive officers,  and principal

               PROPOSAL II. RATIFICATION OF THE APPOINTMENT OF THE
             |_| INDEPENDENT AUDITOR FOR THE FISCAL YEAR ENDING |_|
                                DECEMBER 31, 2006

         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, 2006.  A  representative  from the
firm is expected to be present at the Annual  Meeting to make a statement and to
respond to any 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, 2004 and December 31, 2005,  were $110,850 and $89,050,
respectively.

         Audit-Related  Fees:  In 2004 and 2005,  Stevens,  Powell  also  billed
Atlantic BancGroup $465 and $257,  respectively,  for fees reasonably related to
the performance of its audit and reviews of financial statements, which included
courier costs and postage for confirmations.

         Tax Fees:  In 2004 and  2005,  Stevens,  Powell  also  billed  Atlantic
BancGroup  $4,800 and  $4,800,  respectively,  for tax  compliance  and  advice,
including the  preparation  of Atlantic  BancGroup's  corporate tax returns.  In
2004, tax fees included  reimbursement  of state corporate  annual report filing
fees of $300.

         All Other Fees:  In addition to those fees  described  above,  Stevens,
Powell  also  billed  Atlantic  BancGroup  $4,255  and  $3,435 in 2004 and 2005,
respectively.  For 2004,  these fees were for  attendance  at meetings  covering
planning  for  implementation  of  Section  404  of  the   Sarbanes-Oxley   Act,
consultation for Federal Reserve reporting  requirements,  capital planning, and
amendments to indexed  retirement plan and other accounting  matters,  including
sale of Small Business Administration loans, budgeting,  and training. For 2005,
these fees were for review of audit committee charter,  status of implementation
of  Section  404 of the  Sarbanes-Oxley  Act,  holding  company  accounting  and
reporting to the Federal Reserve, capital planning,  issuance of trust preferred
securities, indexed retirement plan, and other accounting matters.

         In all instances,  Stevens,  Powell's performance of those services was
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 and 2005, 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) and
requests  of  management  of  the  Atlantic   BancGroup  to  provide  accounting
consultation or training.

         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

                  SECTION 16(a) BENEFICIAL OWNERSHIP COMPLIANCE

         Section  16(a) of the  Securities  Exchange  Act of 1934  requires  our
officers,  directors,  and any person who beneficially owns more than 10% of our
common  stock to file reports of  ownership  and changes in  ownership  with the
Securities and Exchange Commission. Executive officers, directors, and more than
10%  shareholders  are required by  regulation  to furnish us with copies of all
Section 16(a) forms which they file.  During 2005,  certain of our directors and
executive  officers  who  own our  stock  filed  Form  3s or  Form  4s with  the
Securities and Exchange  Commission.  The information on these filings  reflects
the  current  ownership  position  of all such  individuals.  To the best of our
knowledge,  during 2005 all such filings by our officers and directors were made
timely,  except Jimmy D. Dubberly,  whose filing of one Form 4 was one day late.

Atlantic BancGroup common stock.
