                                 PROXY STATEMENT

     This Proxy  Statement is furnished in connection  with the  solicitation by
the Board of Directors of AmBase  Corporation  (the  "Company") of proxies to be
voted  at the  Annual  Meeting  of  Stockholders  of the  Company  (the  "Annual
Meeting")  to be held at the  Hyatt  Regency  Hotel,  1800 East  Putnam  Avenue,
Greenwich,  Connecticut, at 9:00 a.m., Eastern Daylight Time, on Friday, May 19,
2006, and at any adjournments thereof. This Proxy Statement and the accompanying
proxy are being mailed to stockholders commencing on or about April 3, 2006.

     Shares  represented  by a duly  executed  proxy  in the  accompanying  form
received by the Company prior to the Annual  Meeting will be voted at the Annual
Meeting in accordance with  instructions  given by the stockholder in the proxy.
Any  stockholder  granting  a proxy  may  revoke  it at any  time  before  it is
exercised by granting a proxy  bearing a later date, by giving notice in writing
to the Secretary of the Company or by voting in person at the Annual Meeting.

     At the  Annual  Meeting,  the  stockholders  will be asked (i) to  re-elect
Robert E. Long as a director of the Company to serve a three-year term ending in
2009; and (ii) to approve the appointment of  PricewaterhouseCoopers  LLP as the
Company's  independent  registered  public  accounting  firm for the year ending

designated  by the Board of Directors  and,  unless  contrary  instructions  are

nominee for director named above;  and (ii) for the approval of the  appointment
of  PricewaterhouseCoopers  LLP as the Company's  independent  registered public
accounting firm.

     The close of business on Monday, April 3, 2006, has been fixed by the Board
of Directors as the record date for the  determination of stockholders  entitled
to notice of and to vote at the Annual Meeting or any adjournments thereof. Only
the holders of record of common stock of the Company,  par value $0.01 per share
(the "Common  Stock") at the close of business on April 3, 2006, are entitled to
vote on the matters presented at the Annual Meeting.  Each share of Common Stock
entitles the holder to one vote on each matter  presented at the Annual Meeting.
As of Monday, April 3, 2006, there were 46,233,519 shares of Common Stock issued
and outstanding.  The holders of a majority of the outstanding  shares of Common
Stock entitled to vote at the Annual Meeting shall constitute a quorum. If there
is less than a quorum,  a  majority  of those  present in person or by proxy may
adjourn the Annual  Meeting.  A  plurality  vote of the holders of the shares of
Common Stock represented in person or by proxy and voting at the Annual Meeting,
a  quorum  being  present,  is  required  for the  election  of  directors.  The
affirmative  vote of the  holders  of a majority  of the shares of Common  Stock
represented  in person or by proxy and  voting at the Annual  Meeting,  a quorum
being present,  is necessary for the approval of  PricewaterhouseCoopers  LLP as
the Company's independent registered public accounting firm.

     Abstentions,   votes  withheld  and  shares  not  voted,  including  broker
non-votes,  are not  included  in  determining  the number of votes cast for the
approval of  PricewaterhouseCoopers  LLP as the Company's independent registered
public accounting firm.  Abstentions,  votes withheld and broker non-votes,  are
counted for  purposes of  determining  whether a quorum is present at the Annual
Meeting.

               INFORMATION CONCERNING THE BOARD AND ITS COMMITTEES

Meetings and Attendance

     During 2005,  the Company's  Board of Directors  held twelve (12) meetings.
Matters were also  addressed by unanimous  written  consent in  accordance  with
Delaware law. All  directors  (except Mr.  Quinn),  attended at least 75% of the
meetings of the Board of Directors and the committees of the Board on which they
served during 2005.

Committees of the Board

     The Board of Directors  currently has (i) an Accounting and Audit Committee
and (ii) a Personnel Committee.

     The Accounting and Audit  Committee met two (2) times during 2005.  Matters
were also  addressed by unanimous  written  consent in accordance  with Delaware
law. The Accounting and Audit  Committee  currently  consists of Robert E. Long,
Chairman,  and Philip M. Halpern and Salvatore  Trani,  who became  directors in
January 2006. Messrs.  Long, Halpern and Trani are independent  directors of the
Company under the applicable  rules of the NASD. Mr. Costello and Mr. Quinn were
members of the  Accounting  and Audit  Committee  until  their  resignations  in
December  2005 and  October  2005,  respectively.  The  Board of  Directors  has
determined that Mr. Long is an "audit committee  financial  expert" as that term
is defined in Item 401(h) of Regulation  S-K  promulgated  by the Securities and
Exchange Commission (the "SEC").

     The  Accounting  and  Audit  Committee  is  directly  responsible  for  the
appointment,  compensation  and  oversight  of the audit and related work of the
Company's independent  auditors.  The Accounting and Audit Committee reviews the
degree  of their  independence;  approves  the  scope of the  audit  engagement,
including the cost of the audit; approves any non-audit services rendered by the
auditors  and the  fees for  these  services;  reviews  with  the  auditors  and
management  the  Company's  policies  and  procedures  with  respect to internal
accounting and financial  controls and, upon completion of an audit, the results
of the audit engagement; and reviews internal accounting and auditing procedures
with the Company's financial staff and the extent to which  recommendations made
by the  independent  auditors have been  implemented.  The  Accounting and Audit
Committee  has adopted a charter,  a copy of which was attached as an exhibit to
the 2004 proxy statement.

     The Personnel  Committee held fourteen (14) meetings in 2005.  Matters were
also addressed by unanimous written consent in accordance with Delaware law. The
Personnel   Committee   currently   consists  of  Mr.  Halpern  and  Mr.  Trani,
Co-Chairpersons,  and Mr. Long.  Mr.  Costello was the Chairman of the Personnel
Committee  until his  resignation in December 2005 and Mr. Quinn was a member of
the Personnel  Committee until his resignation in October 2005.  Messrs.  Trani,
Halpern, and Long are independent  directors of the Company under the applicable
rules of the NASD.

     The  principal  functions of the  Personnel  Committee  are to consider and
recommend  nominees for the Board,  to oversee the  performance  and approve the
remuneration   of  officers  and  senior   employees  of  the  Company  and  its
subsidiaries  and to oversee  and approve the  employee  benefit and  retirement
plans of the Company and its subsidiaries. The Personnel Committee will consider
stockholder  recommendations  for  director,  submitted in  accordance  with the
Company's  By-Laws.  The Personnel  Committee  does not currently have a written
charter.

     The Company's  By-Laws  require that in the event a  stockholder  wishes to
nominate a person for  election as a director,  advance  notice must be given to
the  Secretary  of the  Company not less than 120 days in advance of the date on
which the Company's  proxy  statement is released to  stockholders in connection
with the  previous  year's  annual  meeting of  stockholders,  except that if no
annual  meeting  was  held in the  previous  year or if the  date of the  annual
meeting  has  been  changed  by  more  than  30  calendar  days  from  the  date
contemplated at the time of the previous year's proxy statement, such a proposal
must be received by the Company a  reasonable  time before the  solicitation  is
made, together with the name and address of the stockholder and of the person to
be nominated;  a representation  that the stockholder is entitled to vote at the
meeting  and intends to appear in person or by proxy to make the  nomination;  a
description of arrangements or understandings between the stockholder and others
pursuant to which the nomination is to be made; such other information regarding
the  nominee as would be  required  in a proxy  statement  filed under the proxy
rules as set forth in the  Securities  Exchange  Act of 1934,  as  amended  (the
"Securities  Exchange  Act");  and the  consent  of the  nominee  to  serve as a
director if elected.


                                        3





Communications with Directors

     In order to provide the  Company's  security  holders and other  interested
parties with a direct and open line of  communication to the Board of Directors,
the Board of Directors has adopted the following  procedures for  communications
to directors.  The Company's  security holders and other interested  persons may
communicate  with the Chairman of the Company's  Accounting and Audit Committee,
either of the Co-Chairman of the Personnel Committee, or with the non-management
directors  of the Company as a group,  by mailing a letter  addressed in care of
the  Corporate  Secretary,  AmBase  Corporation,  100 Putnam  Green,  3rd Floor,
Greenwich, Connecticut 06830.

     All  communications  received in accordance  with these  procedures will be
reviewed   initially   by  the   Company.   The  Company  will  relay  all  such
communications  to the  appropriate  director or directors  unless the Secretary
determines that the communication:

     o does  not  relate  to the  business  or  affairs  of the  Company  or the
functioning or  constitution of the Board of Directors or any of its committees;

     o relates to routine  or  insignificant  matters  that do not  warrant  the
attention of the Board of Directors;

     o is an advertisement or other commercial solicitation or communication;

     o is frivolous or offensive; or

     o is otherwise not appropriate for delivery to directors.

     The  director or  directors  who receive any such  communication  will have
discretion to determine whether the subject matter of the  communication  should
be brought to the attention of the full Board of Directors or one or more of its
committees,  and whether any response to the person sending the communication is
appropriate.  Any such response will be made only in accordance  with applicable
law and regulations relating to the disclosure of information.

     The Secretary will retain copies of all communications received pursuant to
these  procedures for a period of at least one year. The Personnel  Committee of
the Board of Directors will review the  effectiveness  of these  procedures from
time to time and, if appropriate, recommend changes.

Board Attendance at Annual Meetings

     We have not established a formal policy  regarding  director  attendance at
our annual meetings of shareholders,  but our directors  generally do attend the
annual  meeting.  The  Chairman of the Board  presides at the annual  meeting of
shareholders,  and the Board of Directors  holds one of its regular  meetings in
conjunction with the annual meeting of shareholders.  Accordingly, unless one or
more  members of the Board are unable to  attend,  all  members of the Board are
expected to be present for the annual  meeting.  All of the four  members of the
Board at the time of the Company's 2005 annual meeting of shareholders  attended
that meeting.

Nomination of Directors

     The Personnel Committee has adopted specifications applicable to members of
the Board of Directors,  and nominees for the Board of Directors  recommended by
the  Personnel  Committee  must meet these  specifications.  The  specifications
provide that a candidate for director should:

     o have a reputation for industry,  integrity, honesty, candor, fairness and
discretion;

     o be  knowledgeable  in his or her chosen  field of  endeavor,  which field
should  have  such  relevance  to our  businesses  as  would  contribute  to the
Company's success;

     o be  knowledgeable,  or  willing  and able to  become so  quickly,  in the
critical  aspects of our businesses  and  operations;  and

     o be  experienced  and  skillful  in  communicating  with and  serving as a
competent  overseer of, and trusted advisor and confidant to senior  management,
of a publicly held corporation or other corporation.




                                        4





     In addition,  nominees for the Board of Directors should  contribute to the
mix of  skills,  core  competencies  and  qualifications  of the  Board  through
expertise in one or more of the following  areas:  accounting  and finance,  the
financial   industry,   international   business,   mergers  and   acquisitions,
leadership,  business and management,  strategic planning, government relations,
investor   relations,    executive   leadership   development,   and   executive
compensation.  The Personnel  Committee  will consider  nominees  recommended by
stockholders  for election at the 2007 Annual Meeting of  Stockholders  that are
submitted prior to December 4, 2006, to our Secretary at the Company's  offices,
100 Putnam Green, 3rd Floor,  Greenwich,  Connecticut  06830. Any recommendation
must be in writing  and must  include a  detailed  description  of the  business
experience and other  qualifications  of the recommended  nominee as well as the
signed  consent of the nominee to serve if nominated  and  elected,  so that the
candidate may be properly  considered.  All stockholder  recommendations will be
reviewed in the same manner as other potential candidates for Board membership.

Section 16(a) Beneficial Ownership Reporting Compliance

     Based  solely  upon a review of the forms  filed  with the SEC and  written
representations  received by the Company pursuant to the requirements of Section
16(a) of the Securities  Exchange Act, the Company  believes that,  during 2005,
there were no transactions which were not reported on a timely basis to the SEC,
no late  reports  nor other  failure  to file a required  form by any  director,
officer or 10% stockholder of the Company.

                INDEPENDENT REGISTERED PUBLIC ACCOUNTANT MATTERS

Report of the Accounting and Audit Committee

     As set forth in more  detail in the  Accounting  and Audit  Committee  (the
"Audit Committee") charter (attached as an Exhibit A to the Company's 2004 Proxy
Statement) the primary  purpose of the Audit Committee is to assist the Board of
Directors in fulfilling its  responsibility to oversee  management's  conduct of
the  Company's  financial  reporting  process,  including  the  oversight of the
following:

     o financial reports and other financial information provided by the Company
to any governmental or regulatory body, the public or other users thereof;

     o the Company's systems of internal accounting and financial controls; and

     o the annual independent audit of the Company's financial statements.

     The Audit Committee reviewed the Company's audited financial statements and
met with both Company management and  PricewaterhouseCoopers  LLP, the Company's
registered  independent  public  accounting  firm,  to discuss  those  financial
statements.  Management has represented to us 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
PricewaterhouseCoopers  LLP 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 the Company.
The Audit Committee also discussed with  PricewaterhouseCoopers  LLP 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 the  Company's  audited  financial  statements  be
included in the  Company's  Annual Report on Form 10-K for the fiscal year ended

Audit Fees

     Aggregate  fees  billed  by  PricewaterhouseCoopers  LLP  for  professional
services rendered for the audit of our annual consolidated  financial statements
included  in  the  Annual  Report  on  Form  10-K  and  the  review  of  interim
consolidated financial statements included in Quarterly Reports on Form 10-Q and
the review and audit of the application of new accounting pronouncements and SEC
releases  were  $58,000 and $54,000  for the years ended  December  31, 2005 and
2004, respectively.

Audit Related Fees

     Aggregate  fees  billed by  PricewaterhouseCoopers  LLP for  assurance  and
related services that are reasonably  related to the performance of the audit or
review of our financial statements and that are not disclosed under "Audit Fees"
above  were  $8,000  and $0 for the  years  ended  December  31,  2005 and 2004,
respectively.  These  audit  related  services  were  for  regulatory  reporting

Tax Fees and All Other Fees

     No other fees  relating  to tax  advisory  or other  services  were paid to
PricewaterhouseCoopers LLP for professional services rendered to the Company for

Audit Committee Pre-Approval Policy

     Pursuant to its charter,  the Audit Committee is responsible for selection,
approving  compensation  and overseeing  the  independence,  qualifications  and
performance of the Company's  independent  accountants.  The Audit Committee has
adopted a pre-approval  policy pursuant to which certain  permissible  audit and
non-audit services may be provided by the independent accountants.  Pre-approval
is  generally  provided  for up to one year,  is detailed  as to the  particular
service or  category of services  and may be subject to a specific  budget.  The
Audit  Committee  may also  pre-approve  particular  services on a  case-by-case
basis.  In  assessing  requests  for  services  by  the  Company's   independent
accountants,  the Audit Committee considers whether such services are consistent
with the auditor's  independence;  whether the Company's independent accountants
are likely to provide the most effective and efficient  service based upon their
familiarity with the Company;  and whether the service could enhance our ability
to manage or control risk or improve audit quality.

     There  were  no  non  audit-related,  tax or  other  services  provided  by
PricewaterhouseCoopers in fiscal year 2005.

Retirement Benefits

     The AmBase  Supplemental  Retirement  Plan,  as amended and  restated  (the
"Supplemental  Plan"), is an unfunded,  non tax-qualified  retirement plan which
has been in effect  since  1985,  under  which  benefits  are based on a varying
percentage  accrual  (historically  ranging  from 2.5% to 4%,  determined  on an
individual basis by the Personnel  Committee) of the participant's  average base
salary and bonus (averaged over the three years of credited service that produce
the  highest  average)  multiplied  by the number of years of the  participant's
credited service,  up to 20 years, plus 1% of his or her average base salary and
bonus  multiplied  by his or her years of credited  service from 20 to 25 years,
plus 0.5% of his or her average base salary and bonus  multiplied  by his or her
years of credited  service in excess of 25 years.  Benefits vest after ten years
of service  although the  Personnel  Committee  may waive or reduce the ten-year
service  requirement  for individual  participants.  Benefits are payable in the
form of a 10-year  life and  certain  annuity or upon the  election  of a vested
participant  whose employment has terminated after ten years of service or after
a change in control of the  Company,  in the form of an  actuarially  equivalent
lump-sum  payment.  Mr.  Bianco is the only  current  executive  officer  of the
Company who  participates in the  Supplemental  Plan and his  Supplemental  Plan
benefits are fully vested,  effective  with the terms of his initial  employment
with the Company in 1991.

     The  following  table  presents,  for  representative  periods of  credited
service,  estimated  annual  benefits  payable  upon  retirement  at the  normal
retirement  age of 60  (under  the  Supplemental  Plan) to  hypothetical  vested
participants  in the  Supplemental  Plan, in the form of a ten-year  certain and
life annuity. For purposes of the Supplemental Plan, accrual has been assumed at
the rate of 4% per year.

     For the purposes of computing accrued benefits under the Supplemental Plan,
Mr.  Bianco had 14.67 years of credited  service as of December 31, 2005 and his
accrual  percentage is 4% in effect from the time of his initial employment with
the Company.  Assuming Mr. Bianco's continued  employment with the Company until
the expiration of his current employment  contract on May 31, 2007, he will have
16.08 years of credited  service for the  computation of accrued  benefits under
the  Supplemental  Plan.  Mr.  Bianco  received  no  benefit  under  the  AmBase
Retirement Plan, a tax-qualified  retirement plan, which was terminated in 1993.
No other employee of the Company is a participant under the Supplemental Plan.

     In consideration  for Mr. Bianco's  agreement to extend his employment with
the Company for an additional five (5) years with no further  Supplemental  Plan
accruals for the extension period, the Company has amended the Supplemental Plan
to provide for the payment to Mr. Bianco of his  Supplemental  Plan benefit in a
lump-sum on or about May 31,  2007 (the date of his  Supplemental  Plan  benefit
entitlement  had he not agreed to extend his employment  with the Company beyond
May 31, 2007).  The Company and Mr. Bianco have further agreed that for purposes
of computing his Supplemental Plan benefit as of May 31, 2007, his Final Average
Earnings (as defined in the Supplemental Plan) will be capped as of December 31,
2004,  a 5.75%  discount  rate will be used and a  "RP-2000"  projected  to 2004
mortality table will be used,  resulting in a Supplemental Plan lump-sum benefit
payment to Mr.  Bianco of  $16,676,115.  The  Company  has  further  amended the
Supplemental Plan to automatically  terminate  following the lump-sum payment to
Mr. Bianco on or about May 31, 2007. See Employment Contracts,  below for a more
complete description of Mr. Bianco's employment agreements with the Company.

     An employment  agreement,  as amended,  is in effect between Mr. Bianco and
the Company,  which  provides for him to serve as Chairman,  President and Chief
Executive  Officer of the Company at an annual  base salary of $625,000  through
May 31, 2007.  The employment  agreement also provides for additional  benefits,
including his  participation  in various  employee  benefit plans,  annual bonus
eligibility,  certain long-term  disability benefits and the accrual of benefits
under the Company's Supplemental Plan at 4% of his average base salary and bonus
(averaged over the three years of credited service that will produce the highest
benefit),  and 100% vesting in his  Supplemental  Plan accrued  benefit.  In the
event the  Company  was to  terminate  his  employment  other  than for  reasons
permitted in the employment agreement, Mr. Bianco would be entitled to receive a
lump-sum  amount equal to the salary  payments  provided  for in the  employment
agreement  for the  remaining  term thereof  following  the passage of a six (6)
month period from his date of termination.

     During March 2006, an additional  employment  agreement  between Mr. Bianco
and the  Company,  effective  June 1, 2007,  has also been  executed  (the "2007
Employment  Agreement").  The terms of the 2007 Employment Agreement provide for
Mr.  Bianco to  continue to serve as  Chairman,  President  and Chief  Executive
Officer of the Company from June 1, 2007  through May 31, 2012.  Under the terms
of the 2007 Employment Agreement,  Mr. Bianco will continue to receive an annual
base salary of $625,000  for the first three (3) years and then is eligible  for
discretionary increases to the amount of his base salary in the fourth and fifth
years.  The 2007  Employment  Agreement  continues to provide for  discretionary
annual  bonuses (which may not take into  consideration  his efforts to obtain a
recovery  for the Company of its  investment  in  Carteret  Savings  Bank,  FA),
employee benefit plans participation, and certain long-term disability benefits;
however,  there will be no further  Supplemental  Plan  benefit  accruals.  (See
Retirement  Benefits above, for further  information with regard to the lump-sum
payment  of Mr.  Bianco's  Supplemental  Plan  benefits).  The  2007  Employment
Agreement provides a long-term  incentive  arrangement for Mr. Bianco,  whereby,
should the Company  receive a recovery  of its  investment  in Carteret  Savings
Bank, FA, through litigation or otherwise  (including the Company's  Supervisory
Goodwill  litigation),  Mr.  Bianco will receive (with  certain  exceptions),  a
lump-sum payment equal to a percentage of that recovery, as follows:

     Long-Term Incentive Award = 5% of the first $50,000,000 of Recovery Amount;

       Plus

     8% of  Recovery  Amount in  excess  of  $50,000,000  but not  greater  than
$150,000,000;

       Plus

     10% of  Recovery  Amount in excess of  $150,000,000  but not  greater  than
$250,000,000;

       Plus

     Discretionary amount (not less than 10%), to be determined by the Board, of
Recovery Amount in excess of $250,000,000.

     Under the terms of the 2007 Employment  Agreement,  if no recovery has been
obtained  by the Company by the  expiration  of the  five-year  term of the 2007
Employment  Agreement,  the Company and Mr.  Bianco will enter into a consulting
arrangement  pursuant to which,  following his employment  with the Company,  he
will continue to provide  services to the Company as an independent  contractor,
solely for the purpose of assisting the Company in obtaining such a recovery.

              PERSONNEL COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Personnel  Committee is responsible for fixing  compensation  and other
employee  benefits  for  executive  officers  of  the  Company.   The  Personnel
Committee's executive  compensation  philosophy is to provide competitive levels
of compensation to its executive  officers through a combination of base salary,
incentive  awards and equity in the  Company.  It is  designed  to reward  above
average corporate  performance,  recognize individual initiative and achievement
and assist  the  Company  in  attracting  and  retaining  qualified  management.
Management  compensation  is  intended  to be set at levels  that the  Personnel
Committee believes fairly reflect the challenges confronted by management.

Overview and Philosophy

     The  Personnel   Committee   believes  that  the  objectives  of  executive
compensation are to attract, motivate and retain the highest quality executives,
align the interests of these executives with those of the Company's stockholders
by encouraging  stock  ownership by executive  officers to promote a proprietary
interest in the  Company's  success,  and to provide  incentives  to achieve the
Company's  goals. In furtherance of these  objectives,  the Company's  executive
compensation  policies  are  designed  to focus the  executive  officers  on the
Company's goals. The Personnel Committee  determines salary,  bonuses and equity
incentives  based upon the performance of the individual  executive  officer and
the Company.

Executive Officers and Chief Executive Officer Compensation

     Base salaries for executive officers are determined initially by evaluating
the  responsibilities of the position,  the experience of the individual and the
competition  in the  marketplace  for  management  talent,  including  companies
confronting  problems of the  magnitude  and  complexity  faced by the  Company.
Annual salary adjustments are determined by evaluating a number of factors.  The
most  important  factor is the  performance  of the  executive,  followed by the
performance  of the  Company,  any  increased  responsibilities  assumed  by the
executive and the  competition  in the  marketplace  for  similarly  experienced
executives.  Salary adjustments are determined and normally made at twelve-month
intervals.

     The  Personnel  Committee  approved cash bonuses for officers and employees
for 2005. Factors considered included performance of the executive,  performance
of the Company,  total compensation  level, the Company's financial position and
other  pertinent  factors.  This analysis was  necessarily a subjective  process
which  utilized no specific  weighting or formula with respect to the  described
factors in determining cash bonuses. Mr. Bianco received base salary payments in
2005 of $625,000 in accordance  with his  employment  agreement.  Mr. Bianco was
paid a bonus of  $625,000  for 2005,  compared  to  $800,000 in each of 2004 and
2003. The Personnel  Committee  considered Mr.  Bianco's work in connection with
the $10 million gain  realized by the Company on the sale of real estate and Mr.
Bianco's  continuing  and integral  role in the Company's  Supervisory  Goodwill
case, and other pending  proceedings  which are significant to the Company.  Mr.
Bianco was also  recognized  for his role in  maintaining a controlled  level of
expenditures,  his management of the Company's  investment returns, and his role
in pursuing several potential acquisitions.

     Pursuant  to Section  162(m) of the  Internal  Revenue  Code,  compensation
exceeding $1 million paid to any of our  executive  officers may not be deducted
by us  unless  such  compensation  is  performance  based and paid  pursuant  to
criteria approved by our shareholders.  The Personnel  Committee  considered the
provisions of Section 162(m) in setting 2005 compensation paid to Mr. Bianco.

     The Company  maintains a Supplemental  Plan, as more fully  described under
Executive  Compensation  - Retirement  Benefits,  above,  which is scheduled for
lump-sum  benefit payout and  termination on or about May 31, 2007, as described
above.

     The Company  believes  that its  compensation  programs,  carefully  mixing
equity and cash incentives,  will continue to focus the efforts of the Company's
executive  officers on  long-term  growth for the benefit of the Company and its
stockholders.

                         STOCK PERFORMANCE GRAPH

     The following graph compares the cumulative total shareholder return on the
Company's  Common  Stock for the past five  years  with the  performance  of the
Standard & Poor's 500 Financials  Index (S&P 500  Financials) and the Standard &
Poor's 500 Stock Index (S&P 500) for that period.  The graph assumes that a $100
investment was made in the Company's Common Stock and each of the indices at the
earliest date shown, and the dividends,  if any, were  reinvested.  No dividends
have been paid by the  Company  over the past five (5)  years.  The stock  price
performance  shown in the graph below  should not be  considered  indicative  of
potential future stock price performance.
