AMENDED EMPLOYMENT AGREEMENT


         This  Amendment  effective as of the 28th day of  December,  1999 to
the Employment  Agreement  effective  July 15, 1999, by and between  RIGGS
NATIONAL CORPORATION (the "Company") and JOE L. ALLBRITTON (the "Executive").
         WHEREAS, the Executive has been the Chief Executive Officer of the
Company since 1982;
         WHEREAS,  the Board of Directors of the Company has determined  that it
is  important  to the  continued  success  of the  Company  to  insure  that the
Executive continue as the Chief Executive Office of the Company for at least the
next five (5) years;
         WHEREAS, the Executive  voluntarily reduced his compensation in 1992 in
order to improve the  profitability of the Company and to assist it in returning
to a healthy and profitable  company with the reasonable  expectation  that once
the Company returned to historic profitability levels, his compensation would be
increased to historic levels and some recognition  would be given to the fact of
his voluntary reduction ; and
         WHEREAS,  the  Board  of  Directors  has  determined  that now that the
Company  has earned  record  profits  that it is  appropriate  to  increase  the
Executive's compensation to levels consistent with his historic compensation and
for the Company to recognize the personal sacrifice of the Executive in reducing
his compensation in order to benefit the Company and its shareholders;
                  NOW, THEREFORE, in consideration of the mutual covenants
hereinafter set forth, the parties agree as follows:
1.       Employment, Term and Duties.
                                      -12-

1.1.     Employment.  The Company  hereby  employs the  Executive  and the
Executive  hereby  accepts  employment by the Company on the terms and
conditions set forth in this Agreement.
1.2. Term. The Executive's employment under this Agreement shall commence on the
date hereof (the "Effective  Date") and shall terminate on July 15, 2004, unless
earlier  terminated  as provided in Section 3 below (the  "Term")
1.3.  Duties. During the Term, the Executive shall serve as the Chief Executive
Officer of the Company, with such customary duties and responsibilities as are
incident to said positions,  including such authority,  duties, and
responsibilities as set forth with respect to such office in the Company's
articles and bylaws. The Executive agrees to devote at least the same amount of
attention  and time to the business and affairs of the Company  and to the
duties and  responsibilities  assigned to the Executive as he has in the past
and will use his reasonable  best efforts to perform  faithfully  and
effectively  such  duties  and  responsibilities.
2.Compensation  and Other Benefits
2.1. Base  Compensation.  As  compensation  for services  rendered  during the
Term,  the Company  shall pay to the Executive an annual salary of $800,000 (the
"Base Salary"). The Compensation Committee of the Board of  Directors  of the
Company (the  "Committee")  shall  conduct an annual review of the Base  Salary
at such time or times as the  Committee  reviews  the annual compensation of its
executives in general,  and, if approved by the Board of Directors,  the
Executive shall be entitled to an increase in the Base Salary as is in
accordance with the then prevailing  policy of the Company with respect to
executive  compensation  in general;  provided,  that such salary may not be
reduced at any time.  The Base Salary  shall be payable in  accordance  with the
payroll  policies  of the  Company as from time to time in effect.
                                      -13-
<PAGE>

2.2.  Annual Performance Bonus.
(1)        In addition to the Base salary,  the  Executive  shall be eligible to
receive,  for each  calendar  year or portion  thereof occurring  during the
Term, an annual  performance  bonus (the "Annual Bonus") in an amount equal to
one hundred fifty percent(150%) of the Executive's Base Salary for such calendar
year or portion  thereof;  provided that the bonus for the year ending December
31, 1999 shall be equal to 150% of the  Executive's  Base Salary for an entire
year.  The amount of any such Annual Bonus shall be based upon the  performance
of the Company and  determined  in  accordance  with the  procedures  set forth
on Exhibit A  hereto.  The Annual Bonus shall be paid to the  Executive at such
time or times as is in  accordance  with the then prevailing policy of the
Company relating to incentive compensation payments.

(2)       No later than the next annual meeting of  shareholders  of the
Company,  the  Company  shall  submit  to  its  shareholders  (the
"Shareholders")  for approval,  with a  recommendation  of the Board of
Directors of the Company of such approval,  an Executive Incentive Plan which,
among other things, covers the Annual Bonus provided for in this Agreement.
If  the  Executive  Incentive  Plan  is  approved  by  the Shareholders,  the
Executive  will be entitled to the Annual  Bonus if earned in  accordance  with
the terms and  conditions  of the Executive Incentive Plan. If the Executive
Incentive Plan is not approved by the Shareholders,  the  Company  shall not be
obligated  to pay the Annual Bonus for any year prior to the year for which the
plan is subsequently approved.  If the Company fails to submit such Executive
Incentive Plan to  the  Shareholders  with  such a  recommendation  by  the
Board  of Directors by the next annual  meeting of  shareholders  of the
Company, the Company  shall  remain  obligated to pay the Annual  Bonuses  which
accrue  after  1999 as and when  they  become  due  under  the terms of
subsection  (a) of this Section 2.2.
                                      -14-
<PAGE>

If the Company is not obligated to pay the Annual Bonus as a result of the
failure of the  Shareholders to approve such Executive  Incentive  Plan, the
Company and the Executive shall  attempt  for a period of 30 days to agree upon
another  form or method of  compensation  to the Executive to adjust for the
loss of the opportunity  to  earn  the  Annual Bonuses.  If the  Company  and
the Executive, each in their sole and absolute discretion, can not agree on
another form or method of  compensation,  the Executive,  upon 30 days written
notice to the Company,  may terminate this Agreement.  In the event of such
termination,  the Executive  shall be entitled to a lump sum payment of one
year's Base Salary and  continuation of all Benefits and Other Benefit Plans for
a period of one year.
2.3.  Participation  in Employee Benefit Plans. The Company agrees to permit the
Executive  during the Term to  participate  in any group  life,  hospitalization
and/or  disability  insurance  plan,  health  program,   supplemental  executive
retirement plan,  nonqualified  compensation plan, pension and/or savings plans,
long-term  incentive  plan,  receive  "fringe  benefits,"  club  memberships and
automobile allowance, and participate in such other benefit plans or programs of
the  Company  (collectively  "Benefits")  subject  to the  generally  applicable
eligibility  requirements relating to such Benefits.
                                      -15-
<PAGE>

The Company also agrees to continue to provide to the Executive  substantially
the same benefits,  programs and  privileges  which it currently  provides to
the  Executive and to implement such other  benefit  plans (the  "Other  Benefit
Plans") for the benefit of the Executive  to the extent the Company  offers its
comparable  senior  executives benefits that are not currently offered by the
Company.  The Company also agrees to provide life insurance to the Executive
during the Term at least  equivalent to the life  insurance  coverage  provided
to the  Executive  under the existing split dollar insurance maintained by the
Company.
2.4. General Business Expenses. The Company shall pay or reimburse the Executive
for all expenses  that are incurred by the Executive in the  performance  of the
Executive's  duties under this Agreement in accordance  with its regular expense
reimbursement policies and procedures upon presentation of such documentation as
the Company customarily requires of its executive employees prior to making such
payments or reimbursements.
2.5. Vacation. During the Term, the Executive shall be entitled to six (6) weeks
of vacation per year.  The  Executive  shall not be permitted to accumulate and
carryover  unused  vacation time or pay from year to year except to the extent
permitted in accordance  with the Company's  vacation policy for senior
executives.
2.6. Tax Withholding.  All payments required to be made to the Executive  shall
be reduced by any amount required to be deducted or withheld  therefrom  by
applicable  law or  regulation.
3.  Termination.
3.1.Termination  upon Death or Disability.  If the Executive  either dies or
becomes entitled to benefits under a Company long-term disability plan or
program during the Term  (whether  before  or  after a  Change  of  Control),
the  Term  shall automatically terminate thereupon,  and the Executive or the
Executive's estate, as the case may be,  shall be  entitled  to  receive,  in
addition  to any life insurance  or  disability  benefits  which are  payable,
as soon as  reasonably practicable after the separate  determinations  thereof,
(i) a lump sum payment equal to the Base Salary for the remaining Term (as
otherwise  determined before such  termination),  (ii) any unpaid vested
Benefits  accrued up to such date of termination,  (iii) an amount equal to the
product of (a) the Annual  Bonus,  if any, otherwise payable with respect to the
year in which the Term is terminated, multiplied  by (b) a  fraction,  the
numerator  of which is the  number of days elapsed in such year as of the
termination  date and the denominator of which is 365.  These items are in
addition to and shall not reduce any other  benefits to which the Executive or
his estate may be entitled.
                                      -16-

3.2.     Other Termination.
(1)      Termination  By  the  Company.  Notwithstanding  any  provision  of the
Agreement to the contrary, the Company, with the approval of a majority of the
Board of Directors,  has the right, at any time during the Term, exercisable by
serving written  notice,  effective on or after the date of  service of such
notice as  specified  therein,  to  terminate  the Executive's  employment
under  this  Agreement  and to  discharge  the Executive with or without Cause.
(2)      Termination  With Cause. Any termination of employment of the Executive
by the Company with Cause shall  terminate  the Term and  thereafter no amounts
shall be payable to Executive  under this Agreement  except (i)his Base Salary
through the date of  termination,  and (ii) any unpaid vested  Benefits,  and
(iii) the Annual Bonuses,  if any,  payable with respect to the prior  calendar
year if it has not yet been paid. All of the foregoing amounts shall be payable
in a lump sum, less such amounts as shall be required to be deducted or withheld
therefrom by applicable law and  regulations,  within  fifteen (15) days after
the  termination date.
                                      -17-
<PAGE>

For  purposes of this  Agreement,  "Cause"  shall mean (i) the conviction  of
the  Executive of a felony  specifically  involving  his actions  with  respect
to the  Company,  (ii) the  Executive's willful refusal  without  legal cause to
perform his duties as Chief  Executive Officer of the Company  which  refusal
continues  for more than thirty (30)  days  after  written  notice to the
Executive  from the Board of Directors of the Company  directing the Executive
to discontinue  same, or (iii) a material breach of his fiduciary duty to the
Company through the misappropriation of funds or property of the Company.
Nothing in this Agreement shall prevent the Executive's  right to terminate his
employment with the Company.
(3)      Termination Without Cause;  Termination by the Employee for Good Reason
or  Termination  Following  Change  of  Control.   Notwithstanding  any
provision  of this  Agreement  to the  contrary,  in the event that the
Executive's  employment is terminated  following a Change of Control of the
Company,  by the Company  without Cause or by the Employee for Good Reason,  the
following  amounts  shall be payable or  provided  by the Company:  (i) the Base
Salary then earned,  but unpaid,  plus an amount equal to the  Base  Salary
which  would  have  been  earned  up to and including  the end of the Term (as
otherwise  determined  before  such termination),  (ii) any unpaid vested
Benefits  accrued to such date of termination,  (iii) an amount  equal to the
aggregate  Annual  Bonuses which would have been  payable on account of any
periods  ending on or before  the  end of the  Term  (as  otherwise  determined
before  such termination)  which bonuses shall, for each such period be equal to
one hundred  fifty percent  (150%) of the then current Base Salary.
                                      -18-
<PAGE>

All of the foregoing amounts shall be payable in a lump sum, less such amounts
as shall be required to be deducted or withheld therefrom by applicable law and
regulations,  within  fifteen (15) days after the  termination date. To the
extent the Executive is eligible thereunder,  for a period through  the end of
the  Term  (as  otherwise  determined  before  such termination),   the
Executive  shall  continue  to  be  provided  life insurance,  disability,
long-term  disability  policies  and any other Benefits  provided  to  the
Executive  on the  date  hereof,  or  such successor   policies   in  effect  at
the  time  of  the   Executive's termination,  and shall also continue to be
covered for the  applicable period by such other  insurance,  disability,
health or other  Benefit program,  plan or  policy  by which he was  covered
at the time of the Executive's  termination.  In the event the  Executive is
ineligible to continue to be so covered  under the terms of any such life
insurance, disability,  long-term disability,  insurance,  health or other
Benefit program,  plan or policy,  the Company  shall  provide to the Executive
through  other  sources  such  benefits,   including  such   additional
benefits,  as may be necessary to make the benefits  applicable  to the
Executive substantially equivalent to those in effect immediately prior to such
termination.
For purposes of this  Agreement,  a "Change of Control" of the Company  shall be
deemed  to occur  upon the  happening  of any of the following:
(1)               individuals who, on the date hereof, constitute the Board (the
"Incumbent  Directors")  cease for any reason to constitute at least a  majority
of the  Board,  provided  that  any  person becoming  a  director  subsequent
to the date  hereof,  whose election or nomination  for election was approved by
a vote of at least  two-thirds  of the Incumbent  Directors  then on the Board
(either by a specific  vote or by approval of the proxy statement  of the
Company in which such  person is named as a nominee  for  director,  without
written  objection  to  such nomination)
                                      -19-
<PAGE>

shall be an Incumbent Director; provided however, that  no  individual
initially  elected  or  nominated  as  a director of the Company as a result of
an actual or threatened election  contest (as  described  in Rule  14a-11  under
the Securities   Exchange  Act  of  1934 (the  "Act")  ("Election Contest")  or
other  actual  or  threatened solicitation  of proxies or consent  by or on
behalf of any  "person"  (as such term is defined  in Section  3(a)(9) of the
Act and as used in Sections  13(d)(3)  and  14(d)(2)  of the Act)  other than
the Board ("Proxy Contest"), including by reason of any agreement intended  to
avoid or settle  any  Election Contest  or Proxy Contest, shall be deemed an
Incumbent Director;
(2)      any  person is or  becomes a  "beneficial  owner"  (as  defined  in
Rule 13d-3  under the Act),  directly  or  indirectly,  of securities of the
Company  representing  25% or more of the combined  voting power of the
Company's then  outstanding securities eligible to vote for the election of the
Board (the "Company Voting Securities");  provided, however, that the event
described in this paragraph (ii) shall not be deemed to be a Change in Control
of the Company by virtue of any of the  following  acquisitions:  (A) by the
Company or any  subsidiary,  (B) by any  employee  benefit  plan (or related
trust) sponsored or maintained by the Company or any subsidiary,  (C) by any
underwriter  temporarily holding securities  pursuant to an offering of such
securities,  (D) pursuant to a Non-Qualifying  Transaction (as defined in
paragraph  (iii)),  (E) pursuant to any acquisition by the Executive or any
group of persons  including the Executive (or any entity  controlled by the
Executive or any group of persons  including the  Executive);  or (F) a
transaction (other than one  described in (iii) below) in which Company
Voting  Securities  are acquired from the Company,  if a majority  of the
Incumbent  Directors  (including  the  Executive  if he is then an  Incumbent
Director)  approve a resolution  providing  expressly  that the  acquisition
pursuant to this clause (F) does not  constitute a Change in Control of the
Company under this paragraph (ii).
                                      -20-

<PAGE>

(3)      the consummation of a merger,  consolidation,  statutory share exchange
or similar form of corporate transaction involving the Company or any of its
subsidiaries  that  requires  the  approval of the  Company's  stockholders,
whether for such transaction or the issuance of securities in the transaction
(a  "Reorganization"),  or sale or other  disposition of all or  substantially
all of the  Company's  assets to an entity that is not an affiliate of the
Company (a "Sale"), unless  immediately  following  such  Reorganization  or
Sale: (A) more than 60% of the total voting power of (x) the corporation
resulting from such Reorganization or the corporation which has acquired all or
substantially all of the assets of the Company (in either case,  the  "Surviving
Corporation),  or (y) if  applicable,  the ultimate  parent corporation  that
directly or indirectly  has  beneficial  ownership of at least a majority of the
voting  securities eligible to elect  directors of the Surviving  Corporation
(the "Parent  Corporation"),  is  represented  by Company Voting  Securities
that were outstanding  immediately  prior to such  Reorganization  or Sale
                                      -21-
<PAGE>

(or, if applicable,  is represented by shares into which such Company Voting
Securities were converted  pursuant to such  Reorganization  or Sale),  and such
voting power among the holders thereof is in  substantially  the same proportion
as the voting power of such Company Voting Securities among the holders thereof
immediately prior to the  Reorganization or Sale, (B) no person  (other than the
Executive and  affiliates  of the Executive or any employee  benefit plan (or
related  trust)sponsored or maintained by the Surviving Corporation or the
Parent Corporation),  is or becomes the beneficial owner, directly or
indirectly,  of 25% or more of the total voting power of the outstanding  voting
securities  eligible to elect directors of the Parent Corporation (or, if there
is no Parent Corporation,  the Surviving Corporation) and (C)at least a majority
of the members of the board of  directors  of the Parent  Corporation  (or, if
there is no Parent Corporation,  the Surviving  Corporation)  following the
consummation of the  Reorganization of the Reorganization or Sale were
Incumbent  Directors  at the time of the  Board's  approval  of the  execution
of the  initial  agreement providing for such  Reorganization or Sale (any
Reorganization or Sale which satisfies all of the criteria specified in (A), (B)
and (C) above shall be deemed to be a "Non-Qualifying Transaction"); or
(4) the stockholders of the Company approve a plan of complete liquidation or
dissolution of the Company. Notwithstanding  the  foregoing,  a Change in
Control  of the Company shall not be deemed to occur solely because any person
acquires beneficial  ownership of more than 25% of the Company Voting
Securities as a result of the  acquisition  of Company Voting  Securities  by
                                      -22-
<PAGE>

the Company which reduces the number of Company Voting Securities outstanding;
provided, that if after such  acquisition  by the  Company  such  person
becomes  the beneficial owner of additional  Company Voting Securities that
increases  the  percentage  of   outstanding   Company  Voting Securities
beneficially  owned by such  person,  a Change  in Control of the Company shall
then occur.
For purposes hereof, "Good Reason" shall mean
(1)                        Removal  without  the  consent  of the  Executive  in
writing,  from  any of the  offices  now  held by the Executive  in the  Company
or any  subsidiary  of the Company,  or any material  reduction  in  Executive's
authority or  responsibility,  other than or a result of  a   termination   for
Cause  or  on  account  of disability.
(2)      The Company otherwise commits a material breach of his Agreement.
3.3. Certain Additional  Payments by the Company.  Anything in this Agreement to
the  contrary  notwithstanding,  in the  event it shall be  determined  that any
payment or  distribution  by the Company to or for the benefit of the Executive,
whether paid or payable or distributed or distributable pursuant to the terms of
this  Agreement or otherwise (a  "Payment"),  would be subject to the excise tax
imposed by Section  4999 of the Internal  Revenue Code of 1986,  as amended (the
"Code") or any  interest  or  penalties  with  respect to such  excise tax (such
excise tax,  together  with any such  interest and  penalties,  are  hereinafter
collectively  referred  to as the "Excise  Tax"),  then the  Executive  shall be
entitled to receive an  additional  payment (a "Gross-Up  Payment") in an amount
                                      -23-
<PAGE>

such that after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes),  including any Excise Tax imposed
upon the  Gross-Up  Payment,  the  Executive  retains an amount of the  Gross-Up
Payment  equal to the  Excise  Tax  imposed  upon the  Payments.  Subject to the
provisions  of  this  Section  3.3,  all  determinations  required  to  be  made
hereunder,  including  whether a Gross-Up  Payment is required and the amount of
such Gross-Up  Payment,  shall be made by Ernst & Young or such other accounting
firm selected by the Executive  (the  "Accounting  Firm") at the sole expense of
the Company,  which shall provide detailed  supporting  calculations both to the
Company and the  Executive  within  fifteen  (15)  business  days of the date of
termination of the Executive's  employment under this Agreement,  if applicable,
or such earlier time as is requested  by the  Company.  If the  Accounting  Firm
determines  that no Excise Tax is payable by the Executive,  the Accounting Firm
shall furnish the Executive  with an opinion that he has  substantial  authority
not to report any Excise Tax on his federal income tax return. Any determination
by the Accounting Firm shall be binding upon the Company and the Executive. As a
result of the  uncertainty in the application of Section 4999 of the Code at the
time of the  initial  determination  by the  Accounting  Firm  hereunder,  it is
possible  that Gross-Up  Payments,  which will not have been made by the Company
should  have been made (an  "Underpayment"),  consistent  with the  calculations
required to be made  hereunder.  If the Company  exhausts its remedies  pursuant
hereto and the Executive  thereafter is required to make a payment of any Excise
Tax, the Accounting Firm shall determine the amount of the Underpayment that has
occurred and any such  Underpayment  shall be promptly paid by the Company to or
for the benefit of the Executive.
                                      -24-
<PAGE>

         The  Executive  shall notify the Company in writing of any claim by the
Internal  Revenue Service that, if successful,  would require the payment by the
Company of the Gross-Up  Payment.  Such  notification  shall be given as soon as
practicable  but no later than ten business  days after the  Executive  knows of
such  claim and shall  apprise  the  Company of the nature of such claim and the
date on which such claim is requested to be paid.  The  Executive  shall not pay
such claim prior to the  expiration of the 30-day  period  following the date on
which it gives such notice to the Company (or such shorter  period ending on the
date that any  payment  of taxes  with  respect  to such  claim is due).  If the
Company notifies the Executive in writing prior to the expiration of such period
that it desires to contest such claim, the Executive shall:
(1) give the Company any information reasonably requested by the Company
relating to such claim,
(2)      take such  action  in  connection  with  contesting  such  claim as the
Company  shall  reasonably  request  in  writing  from  time  to  time,
including  (without  limitation)  accepting legal  representation  with respect
to  such  claim  by an  attorney  reasonably  selected  by the Company,
(3) cooperate with the Company in good faith to contest  effectively such claim,
and
(4)      permit the Company to participate in any  proceedings  relating to such
claim; provided that the Company shall bear and pay directly all ,costs and
expenses (including  additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Executive harmless,  on an
after-tax  basis,  for any Excise Tax or income  tax, including  interest and
penalties  with respect  thereto,  imposed as a result  of such  representation
                                      -25-
<PAGE>

and  payment  of costs  and  expenses. Without limitation on the foregoing
provisions hereof the Company shall control all  proceedings  taken in
connection with such contest and, at its  sole  option,  may  pursue  or  forgo
any and all  administrative appeals,   proceedings,   hearings  and  conferences
with  the  taxing authority in respect of such claim and may, at its sole
option,  either direct the  Executive  to pay the tax  claimed  and sue for a
refund or contest the claim in any permissible  manner,  and the Executive
agrees to prosecute such contest to a determination  before any administrative
tribunal,  in a  court  of  initial  jurisdiction  and in  one or  more
appellate courts, as the Company shall determine,  provided that if the Company
directs the  Executive to pay such claim and sue for a refund, the Company shall
advance the amount of such payment to the  Executive, on an  interest-free
basis and shall  indemnify and hold the Executive harmless,  on an  after-tax
basis,  from any Excise Tax or income tax, including  interest or  penalties
with respect  thereto,  imposed with respect to such  advance or with  respect
to any  imputed  income  with respect to such advance, and further provided that
any extension of the statute of  limitations  relating  to payment of taxes for
the  taxable year of the Executive  with respect to which such  contested
amount is claimed  to  be  due  is  limited  solely  to  such  contested
amount. Furthermore,  the Company's  control of the contest shall be limited to
issues  with  respect  to which a  Gross-Up  Payment  would be  payable
hereunder and the Executive shall be entitled to settle or contest,  as the case
may be, any other issue raised by the Internal Revenue Service or any other
taxing authority.
                                      -26-
<PAGE>

                 If, after the receipt by the  Executive of an amount  advanced
by the Company  pursuant  hereto,  the  Executive  becomes  entitled to receive
any refund  with  respect to such claim,  the  Executive  shall (subject  to the
Company's  complying  with the  requirements  hereof) promptly  pay to the
Company the amount of such refund  (together  with any interest paid or credited
thereon after taxes applicable  thereto). If,  after the receipt by the
Executive  of an amount  advanced by the Company  pursuant  hereto,  a
determination  is made that the Executive shall not be entitled to any refund
with  respect to such claim and the Company  does not  notify  the  Executive
in  writing of its intent to contest  such denial of refund prior to the
expiration  of thirty (30) days after such determination,  then such advance
shall be forgiven and shall not be required to be repaid and the amount of such
advance shall offset, to the extent thereof,  the amount of Gross-Up Payment
required  to be paid.
4.       Other Provisions.
4.1.  Nondisclosure.  During  the term of this  Agreement  and  thereafter,  the
Executive  shall  not,  without  the  prior  written  consent  of the  Board  of
Directors,  disclose  or use  for  any  purpose  (except  in the  course  of his
employment  under this  Agreement  and in  furtherance  of the  business  of the

                                  EXHIBIT A


         Any capitalized  term used herein which is not otherwise  defined shall
have the meaning attributed to it in the Executive's  Employment  Agreement (the
"Employment Agreement").

         The Employment  Agreement  provides that the Executive shall be paid an
Annual Bonus as determined  by the  Compensation  Committee  (or a  subcommittee
thereof comprised solely of "outside  directors,"  within the meaning of Section
162(m)  of the  Internal  Revenue  Code  of  1986,  if the  Committee  is not so
comprised,  and references herein to the Compensation  Committee shall be deemed
references  to such  subcommittee).  The purpose of this Exhibit is to set forth
the procedure for (i) setting the annual  objectives (the  "Objective") for each
year,  (ii)  determining  whether the  Objective  has been  obtained,  and (iii)
setting the magnitude of the Annual Bonus based upon the  Company's  performance
vis-a-vis the Objective.

         On or prior to February 28 of each calendar year,  the Executive  shall
submit a proposed business plan to the Compensation Committee. The business plan
shall set forth a forecast  of the net income  after tax for the Company for the
then current  year.  The proposed  business  plan shall be subject to review and
approval by the  Compensation  Committee.  The  Executive  and the  Compensation
Committee  shall  discuss  in good  faith any  revisions  to the  proposed  plan
required by the Compensation  Committee,  but notwithstanding  such discussions,
the business plan shall be subject to the approval of the Compensation Committee
in the exercise of its discretion.  On or prior to the 90th day of each calendar
year, the Compensation  Committee shall  determine,  based on the business plan,
specific objective  performance  criteria which must be met for the Executive to
receive the Annual Bonus;  provided however,  the Executive shall be entitled to
receive an Annual Bonus with respect to calendar  year 1999 if the Company's net
income  available  for Common Stock for the five months ended  December 31, 1999
equals or exceeds an amount determined by the Compensation Committee on or prior
to August 27, 1999.

         Within  ten (10)  days  after  the year end  financial  results  of the
Company are made available to the  Compensation  Committee,  it shall  determine
whether,  in its good faith  judgment,  the  Objective has been met or exceeded.
Based  upon  the  Compensation  Committee's  conclusions  with  respect  to  the
Company's performance  vis-a-vis the Objective,  the Executive shall be entitled
to the Annual Bonus.
