Dear Stockholder:

         You are  cordially  invited  to  attend  the  2000  Annual  Meeting  of
Stockholders of Niagara Bancorp,  Inc. (the "Company").  The Annual Meeting will
be held at the Pendleton House, 6886 South Transit Road, Pendleton, New York, on
Tuesday, May 2, 2000 at 10:00 a.m., Eastern Standard Time.

         The enclosed Notice of Annual Meeting and Proxy Statement  describe the
formal business to be transacted.  During the Annual Meeting we will also report
on the  operations  of the Company and First  Niagara  Bank  (formerly  Lockport
Savings Bank) (the "Bank"), the Company's wholly-owned subsidiary. Directors and
officers  of  the  Company  will  be  present  to  respond  to  questions   that
stockholders  may have.  Also  enclosed for your review is our Annual Report and
Form 10-K to Stockholders,  which contains detailed  information  concerning the
activities and operating performance of the Company.

         The  business to be  conducted  at the Annual  Meeting  consists of the
election of four  directors,  the  approval  of an  amendment  to the  Company's
certificate  of  incorporation  to change  our name to First  Niagara  Financial
Group, Inc., and the ratification of the appointment of independent auditors for
the year ending December 31, 2000. In addition,  a shareholder proposal has been
submitted for  consideration by  stockholders.  For the reasons set forth in the
Proxy  Statement,  the Board of Directors of the Company has determined that the
matters to be considered  at the Annual  Meeting are in the best interest of the
Company and its stockholders,  and the Board of Directors unanimously recommends
a vote "FOR" the election of  directors,  "FOR" the  amendment to the  Company's
Certificate of  Incorporation,  and "FOR" the ratification of the appointment of
KPMG LLP as the  Company's  Auditors.  The Board of Directors  recommends a vote
"AGAINST" the stockholder proposal.

         On  behalf  of the Board of  Directors,  we urge you to sign,  date and
return the enclosed  proxy card as soon as possible,  even if you currently plan
to attend the Annual  Meeting.  This will not prevent you from voting in person,
but will  assure  that  your vote is  counted  if you are  unable to attend  the
meeting.  Your vote is  important,  regardless  of the number of shares that you
own.

                                         Sincerely,


                                         William E. Swan

         Stockholders  who execute  proxies in the form solicited  hereby retain

Certificate of  Incorporation  authorizes the Board of Directors (i) to make all
determinations necessary to implement and apply the Limit, including determining
whether  persons or entities are acting in concert,  and (ii) to demand that any
person who is  reasonably  believed to  beneficially  own stock in excess of the
Limit supply  information  to the Company to enable the Board to  implement  and
apply the Limit.  This  Limit  does not apply to shares of Common  Stock held by
Niagara Bancorp, MHC.

                       PROPOSAL I - ELECTION OF DIRECTORS
- --------------------------------------------------------------------------------


         The  Company's  Board of  Directors  is  currently  composed  of eleven
members.  The  Company's  Bylaws  provide  that  approximately  one-third of the
Directors  are to be elected  annually.  Directors of the Company are  generally
elected to serve for a three-year  period or until their  respective  successors
shall have been elected and shall qualify.  Each of the Directors of the Company
also  serves  on the board of  directors  of the Bank.  Four  Directors  will be
elected  at  the  Company's  Annual  Meeting  of  Stockholders  to  serve  for a
three-year period and until their respective  successors shall have been elected
and shall qualify. The Board of Directors has nominated Ms. Caldwell and Messrs.
Fitch, Judge and Miklinski for election as Directors.

         The  following  table sets forth certain  information,  as of March 22,
2000, regarding members of the Company's Board of Directors, including the terms
of office of Board members.  It is intended that the proxies solicited on behalf
of the Board of  Directors  (other than proxies in which the vote is withheld as
to the  nominees)  will be voted at the Meeting for the election of the nominees
identified below. If the nominees are unable to serve, the shares represented by
all such proxies will be voted for the election of such  substitute as the Board
of Directors may  recommend.  At this time,  the Board of Directors  knows of no
reason why the nominees might be unable to serve, if elected.

                                        3





Except as indicated herein, there are no arrangements or understandings  between
the nominees and any other person pursuant to which such nominees were selected.

Meetings of the Board and Committees of the Board

         The Board of  Directors of Niagara  Bancorp  meets  quarterly,  or more
often as may be  necessary.  The Board of  Directors of the Company has an audit
committee,  an  executive  committee  and a  compensation  committee.  The  Bank
maintains a loan committee,  audit committee,  finance and investment  committee
and compensation committee.

         The Board of  Directors  of the Company met nine times and the Board of
Directors of the Bank met twelve times during 1999. No Director  attended  fewer
than 75% in the  aggregate  of the total number of Board  meetings  held and the
total number of committee meetings on which he or she served during 1999.

         The executive  committee consists of Directors  Heinrich,  Swan, Assad,
Judge and Weber.  The executive  committee  meets as necessary when the Board is
not in session to  exercise  general  control  and  supervision  in all  matters
pertaining  to the  interests  of Niagara  Bancorp,  subject at all times to the
direction of the Board of Directors.  The  executive  committee met ten times in
1999.

         The nominating  committee  consists of Directors  Miklinski,  Caldwell,
Fitch,  Heinrich and Smith.  The nominating  committee  meets for the purpose of
identifying,  evaluating and recommending  potential  candidates for election to
the  Board.   While  the  committee  will  consider   nominees   recommended  by
stockholders,  it has not actively solicited  recommendations from stockholders.
Nominations   by   stockholders   must  comply  with  certain   procedural   and
informational  requirements  set forth in the  Company's  Bylaws.  See  "Advance
Notice of  Business  to be  Conducted  at an  Annual  Meeting."  The  nominating
committee met two times in 1999.

         The audit  committee  consists of  Directors  Weber,  Currie,  Mancuso,
Miklinski and Heinrich.  The audit committee meets at least quarterly to examine
and approve the audit report prepared by the  independent  auditors of the Bank,
to review  and  recommend  the  independent  auditors  to be  engaged by Niagara
Bancorp,  to review the internal audit function and internal accounting controls
of  Niagara  Bancorp,  and to  review  and  approve  audit  policies.  The audit
committee met four times in 1999.

         The compensation committee consists of Directors Heinrich, Assad, Judge
and  Weber.  This  committee  reviews  and  administers  compensation,   officer
promotions,  benefits and other matters of personnel  policy and  practice.  The
compensation committee met eleven times during fiscal 1999.

Compensation of Directors

         Fees.  Directors of the Bank receive a retainer fee of $12,000 ($17,000
for the  Chairman),  plus a fee of $700 per board meeting  attended and $400 per
meeting for attendance at committee  meetings.  Directors who are also employees
of the Bank are not  eligible to receive  board fees.  Directors  of the Company
receive  an annual  retainer  fee of $5,000  and a fee of $400 per  meeting  for
attendance at board and committee meetings.

                                        6





         Deferred Fees Plan.  The Directors'  Deferred Fees Plan  ("Deferred Fee
Plan") is a non-qualified  deferred  compensation plan into which a director can
defer  up to 100% of his or her  board  retainer  and  fees  earned  during  the
calendar year. All amounts deferred by a Director are fully vested at all times.
Amounts  credited to a deferred fee account are  invested in equity  securities,
fixed income securities, money market accounts, and cash, at the sole discretion
of the Bank. Upon cessation of a Director's service with the Bank, the Bank will
pay the director the amounts credited to his or her account. The amounts will be
paid in a number of substantially equal annual installments,  as selected by the
Director at the time the deferral is made.

         If the Director dies before all payments have been made,  the remaining
payments will be made to the Director's designated beneficiary.  In the event of
the Director's  death prior to commencement of benefits,  the Bank shall pay the
director's beneficiary the amounts credited to the benefit of the Director under
the  Deferred  Fee  Plan,  in a  single  lump  sum  payment  or in a  number  of
substantially  equal annual  installments as elected by the Director at the time
the election to defer was made. In the event of an unforeseeable emergency which
will  result  in a  severe  financial  hardship,  the  Director  may  request  a
distribution  of  all  or  part  of  his or  her  benefits  or  may  request  an
acceleration of benefits that are being paid, as applicable.

         Stock Option Plan and  Recognition and Retention Plan. The Stock Option
Plan and  Recognition  and  Retention  Plan  ("RRP") was adopted by the Board of
Directors of the Company and subsequently approved by the Company's shareholders
at the  adjourned  annual  meeting  held  on May  18,  1999  (the  "1999  Annual
Meeting").  On May 20, 1999, the effective date of the Option Plan, each Outside
Director of the Company and the Bank was granted a non-qualified stock option to
purchase 27, 300 shares of Common Stock.  These options are scheduled to vest at
the rate of 20% per year over a  five-year  period and will  become  immediately
exercisable upon the director's death or disability. Similarly, on May 20, 1999,
the  effective  date of the RRP,  restricted  stock  awards were granted to each
director  with  respect to 6,700 shares of Common  Stock.  These awards are also
scheduled to vest in 20% increments over a five-year period beginning on May 20,
2000,  except that the awards for Mr.  Smith and Mrs.  Calwell will vest 100% at
his or her age 70, respectively,  with accelerated vesting to occur in the event
of the director's death or disability.

Report of the Compensation Committee on Executive Compensation

         Under rules  established by the SEC, the Company is required to provide
certain data and information in regard to the compensation and benefits provided
to its Chief  Executive  Officer and other  executive  officers.  The disclosure
requirements  for the  Chief  Executive  Officer  and other  executive  officers
include  the  use  of  tables  and  a  report   explaining   the  rationale  and
considerations  that  led  to  fundamental  executive   compensation   decisions
affecting those  individuals.  The Chief  Executive  Officer and other executive
officers  have not received  compensation  from the Company.  Consequently,  the
compensation  discussed in the  Compensation  Committee  Report  relates to that
provided by the Bank.

         The Compensation Committee annually reviews and recommends changes to
the compensation levels of the executive officers to the Board of Directors.
Since the Company's

                                        8





conversion to a stock company, the Compensation Committee has begun a process to
revise the  compensation  program to better reflect the Company's public status.
It is  intended  that the new  executive  compensation  program  will enable the
Company and the Bank to attract,  develop and retain strong  executive  officers
who are capable of maximizing the Company's  performance  for the benefit of the
shareholders.  The Committee has adopted a  compensation  strategy that seeks to
provide competitive compensation that is strongly aligned with the financial and
stock  performance of the institution.  The  compensation  program has three key
elements: base salary, annual incentives and long-term incentives.

         In 1999,  an  independent  review of the  competitiveness  of the total
compensation  of the executive  group was  conducted by a nationally  recognized
compensation  consulting  firm.  Compensation  levels  were  compared  to  other
comparably sized national and regional  community  banks. The review  determined
that base  salaries  and combined  base  salaries  and the  combination  of base
salaries and cash  incentives  approximated  median levels provided by similarly
situated community banking companies.

         Base  salary and  changes to base  salary  reflect a variety of factors
including the results of the independent  review of the  competitiveness  of the
total compensation program,  contribution to the long-term goals of the Company,
and  recent  results.  Each of the  named  executive  officers  is a party to an
employment  agreement with the Bank  providing for a minimum base salary,  which
may be increased,  but not  decreased.  Payouts under the annual  incentive plan
(the  management  incentive  plan, or "MIP") are  determined by return on equity
performance  relative to other similarly situated companies.  Individual payouts
are a function of the Company's financial performance and the performance of the
individual executive.  The Committee believes that this funding formula provides
a direct link between financial  performance and actual compensation.  The range
in incentive  opportunities  under the MIP for executives and all other officers
reflect  opportunities  slightly  below the median of those provided for similar
positions by similarly situated community banks.

         On May 18, 1999,  the  Company's  shareholders  adopted the 1999 Option
Plan and 1999 Recognition and Retention Plan for outside  directors,  executives
and other  employees.  Awards of stock options and restricted stock were made to
the executive  officers at that time. The options are exercisable and the shares
vest at the rate of 20% per year over a five-year period. The Committee believes
that  long-term  incentives  are the most  effective  way of aligning  executive
rewards  with  the  creation  of  value  for  the  shareholders   through  stock
appreciation.  Future  awards will be  dependent  on the Company and  individual
performance, as well as competitive market conditions.

         In making  determinations as to Mr. Swan's  compensation, the Committee
is operating  under  the terms of the  previously disclosed employment agreement
between Mr. Swan and the  Company.  Mr.  Swan's  base  salary was  increased  to
$330,000 in 1999 and he was provided a cash bonus of $133,575.  Mr. Swan's bonus
was provided  under the terms of the MIP.  During fiscal 1999, and as identified
in the Summary  Compensation  Table,  Mr. Swan was granted 182,000 stock options
and 45,000  restricted  shares under the  Recognition  and Retention  Plan.  The
Compensation  Committee  determined  these  awards  based  on:  a study of other
comparable institutions, its philosophy on the

                                        9





importance of emphasizing equity participation,  and its evaluation of the CEO's
long-term  contribution to the Company's  performance.  The Committee took these
actions to  recognize  the CEO's  accomplishments  in  successfully  building an
institution  and  management  team capable of becoming a public  company and his
ability to manage the ongoing transition and future direction of the Company.

Employment Agreements

         The Bank has entered into employment  agreements with each of the Named
Executive   Officers.   The  employment   agreements  have  terms  ranging  from
twenty-four  to  thirty-six  months.  On each  anniversary  date,  an employment
agreement may be extended for an additional twelve months, so that the remaining
term shall be from twelve to thirty-six months. If the agreement is not renewed,
the  agreement  will  expire  at the  end  of its  term.  Under  the  employment
agreements, the 2000 Base Salary for Messrs. Swan, Kolkmeyer, Berner and for Ms.
Monti and Ms. Allegro is $330,000,  $182,000,  $153,000, $138,000, and $120,000,
respectively. The Base Salary may be increased but not decreased. The employment
agreements  also provide that the  executive  is entitled to  participate  in an
equitable manner with other executive officers in discretionary bonuses declared
by the  Board.  In  addition  to the  Base  Salary  and  bonus,  the  employment
agreements  provide for, among other things,  participation  in retirement plans
and other employee and fringe benefits  applicable to executive  personnel.  The
agreements  provide for  termination  by the Bank for cause at any time.  In the
event the Bank involuntarily  terminates the executive's  employment for reasons
other  than for  cause,  the  executive,  or in the event of  death,  his or her
beneficiary would be entitled to severance pay in an amount equal to three times
Base Salary (in the case of Messrs.  Swan and Kolkmeyer),  two times Base Salary
(in the case of Mr.  Berner,  Ms. Monti and Ms.  Allegro).  For these  purposes,
involuntary  termination includes a constructive  termination where the Bank (i)
fails to appoint or reappoint the executive to his or her present position, (ii)
materially changes the executive's functions, duties or responsibilities,  which
change   would  cause  the   executive's   position  to  become  one  of  lesser
responsibility,  importance or scope,  (iii) relocates the executive's  place of
employment by more than 100 miles,  (iv)  liquidates or dissolves  other than in
connection with a Reorganization that does not affect the executive's status, or
(v) a breach  of the  employment  agreement.  The Bank will  also  continue  the
executive's  health  coverage  through  the  remaining  term  of the  employment
agreement.  In the event the payments to the executive  would include an "excess
parachute payment" as defined by Code Section 280G (relating to payments made in
connection with a change in control),  the payments would be reduced in order to
avoid having an excess parachute payment.

         In the event of an executive's  death while employed during the term of
an  employment  agreement,   the  Bank  will  pay  the  executive's  estate  the
executive's  salary through the end of the calendar month in which the executive
dies. If the  executive  becomes  disabled (as defined in the Bank's  disability
plan),  the  employment  agreement will remain in effect through the term of the
agreement,  except that the  executive's  salary payments will be reduced by any
disability insurance payments made to the executive.

Deferred Compensation Plan

          The Bank has adopted the First Niagara Bank Deferred Compensation Plan
("Non-qualified  Plan") for the benefit of certain senior executives of the Bank
that it has designated to participate in the plan. Under the Non-qualified Plan,
the Bank annually credits an executive's  deferred  compensation account with an
amount determined in the sole discretion of the Board. The amounts

                                       10





credited to the executive's deferred  compensation account are annually credited
with  earnings,  at a rate  determined in the sole  discretion of the Board.  An
executive  will vest in amounts  credited  to his account at the rate of 20% per
year,  beginning in the sixth year of  participation  in the  Nonqualified  Plan
until the executive is fully vested after 10 years of  participation.  For these
purposes, an executive's years of participation will be equal to the executive's
number of whole years of employment with the Bank measured from the date that an
executive  becomes a participant under the Plan.  Notwithstanding  the above, an
executive  shall be fully  vested  in his  deferred  compensation  account  upon
attaining age 60 with five years of participation or in the event of a change in
control  of  the  Bank.  Benefits  are  payable  to  the  executive  in  fifteen
substantially  equal annual payments  commencing (i) 30 days after the executive
has attained age 60, or (ii) 30 days after the executive terminates  employment,
if after age 60, or due to  disability.  In the event of the  executive's  death
after  benefits  commence,  the Bank  will  pay the  remaining  benefits  to the
executive's  beneficiary over the remainder of the payment term. In the event of
the executive's  death after termination of employment but prior to commencement
of  benefit  payments,  the  Bank  will  pay  the  executive's  benefit  to  the
executive's   beneficiary  in  fifteen   substantially   equal  annual  payments
commencing  within  30  days  of the  executive's  death.  In the  event  of the
executive's death prior to termination of employment, the executive will forfeit
all benefits  under the  Non-qualified  Plan.  In the event of an  unforeseeable
emergency which will result in a severe  financial  hardship,  the executive may
request  a  distribution  of all or  part  of his  benefits  or may  request  an
acceleration of benefits that are being paid to him, as applicable.

     Messrs. Swan,  Kolkmeyer,  and Berner and Ms. Monti are participants in the
Non-qualified  Plan.  For the  year  ended  December  31,  1999,  Messrs.  Swan,
Kolkmeyer, and Berner, and Ms. Monti, had $38,414, $16,813, $15,884 and $11,957,
respectively, credited to their deferred compensation accounts.

Defined Benefit Pension Plan

         The Bank  maintains  the  Retirement  Plan of First Niagara Bank in RSI
Retirement Trust  ("Retirement  Plan") which is a qualified,  tax-exempt defined
benefit plan. Employees age 21 or older who have worked at the Bank for a period
of one year and have been  credited with 1,000 or more hours of service with the
Bank during the year are eligible to accrue benefits under the Retirement  Plan,
provided, however that leased employees, employees paid on a contract basis, and
employees  employed  off-site in connection with the operation or maintenance of
properties acquired through foreclosure or deed are not eligible to participate.
The Bank contributes  each year, if necessary,  an amount to the Retirement Plan
to satisfy the actuarially determined minimum funding requirements in accordance
with the Employee  Retirement Income Security Act of 1974, as amended ("ERISA").
For the plan year ended September 30, 1999, no  contribution  was required to be
made by the Bank to the Retirement Plan. At September 30, 1999, the market value
of the Retirement Plan trust fund equaled approximately $10.3 million.

         In the event of retirement at normal retirement age (i.e., the later of
age 65 or the 5th anniversary of participation in the Retirement Plan), the plan
is designed to provide a single life

                                       11





annuity. For a married participant, the normal form of benefit is an actuarially
reduced joint and survivor  annuity where,  upon the  participant's  death,  the
participant's  spouse is entitled to receive a benefit equal to 50% of that paid
during the participant's lifetime.  Alternatively, a participant may elect (with
proper spousal consent,  if necessary) a joint and 100% survivor annuity,  or an
annuity   payable  for  a  period  certain  and  life.  All  forms  in  which  a
participant's  benefit may be paid will be actuarially  equivalent to the single
life annuity.  The retirement benefit provided is an amount equal to (a) 2% of a
participant's  average annual earnings  multiplied by credited  service prior to
April  1,  1998  plus (b)  1.25%  of a  participant's  average  annual  earnings
multiplied by the participant's  years of credited service  thereafter,  up to a
maximum of 30 years. Retirement benefits are also payable upon retirement due to
early and late  retirement  or death.  A reduced  benefit is payable  upon early
retirement  at age 60,  at or  after  age 55 and the  completion  of 20 years of
vested service with the Bank, or after completion of 30 years of vested service.
Upon  termination of employment other than as specified above, a participant who
has five years of vested  service after age 18 is eligible to receive his or her
accrued benefit commencing,  generally,  on such participant's normal retirement
date.

         The following table indicates the annual retirement  benefit that would
be payable under the Retirement  Plan upon retirement at age 65 in calendar year
1999,  expressed  in the form of a single  life  annuity  for the final  average
salary and benefit service classifications specified below.

Ownership Reports by Officers and Directors

         The Common Stock of the Company is registered  with the SEC pursuant to
Section 12(g) of the Securities  Exchange Act of 1934 (the "Exchange  Act"). The
officers and Directors of the Company and beneficial  owners of greater than 10%
of the  Company's  Common Stock are required to file reports on Forms 3, 4 and 5
with the SEC disclosing beneficial ownership and changes in beneficial ownership
of the  Common  Stock.  SEC rules  require  disclosure  in the  Company's  Proxy
Statement or Annual  Report on Form 10-K of the failure of an officer,  director
or 10% beneficial  owner of the Company's Common Stock to file a Form 3, 4, or 5
on a timely  basis.  All of the  Company's  officers and  Directors  filed these
reports on a timely basis.

Transactions With Certain Related Persons

         Federal  law and  regulation  generally  requires  that  all  loans  or
extensions  of  credit  to  executive  officers  and  directors  must be made on
substantially the same terms, including interest rates and collateral,  as those
prevailing at the time for comparable  transactions  with the general public and
must not  involve  more than the  normal  risk of  repayment  or  present  other
unfavorable features.  However, recent regulations now permit executive officers
and directors to receive the same terms through  benefit or  compensation  plans
that  are  widely  available  to other  employees,  as long as the  director  or
executive  officer is not given  preferential  treatment  compared  to the other
participating employees. Pursuant to such a program, the Bank has extended loans
to Directors Judge, Mancuso,  Weber and President Swan, Executive Vice President
Kolkmeyer and Executive Vice President Monti.

         Set forth below is certain  information as to loans made by the Bank to
certain of its directors  and executive  officers,  or their  affiliates,  whose
aggregate indebtedness to the Bank exceeded $60,000 at any time since January 1,
1999.  Unless  otherwise  indicated,  all of the loans are secured loans and all
loans  designated as  residential  loans are first mortgage loans secured by the
borrower's principal place of residence. [Update]

During the past  eighteen  months,  the Bank has  expanded  into the  insurance,
leasing and third party benefits  administration  through several  acquisitions.
The Company has announced two  acquisitions  of savings  institutions,  the most
recent  of  which,  Cortland  Savings  Bank,  will  be  operated  as a  separate
subsidiary of the Company. The change in the Bank's name was intended to reflect
its  repositioning  from a consumer  savings  bank to a  full-service  financial
services  organization  serving  regional and national  markets.  The purpose of
changing the Company's  name is to link the entire  organization  under a common
brand focused on providing a unique financial services experience. The vote of a
majority of the shares  outstanding and entitled to vote is necessary to approve
the amendment to the certificate of incorporation.



               THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE
           APPROVAL OF THE AMENDMENT TO THE COMPANY'S CERTIFICATE OF
                                 INCORPORATION.

                       PROPOSAL IV - STOCKHOLDER PROPOSAL
- --------------------------------------------------------------------------------


     Jewelcor Management, Inc. is the record owner of 250 shares of Common Stock
and is the beneficial owner of 26,350 shares of Common Stock, and its address is
100 North Wilkes- Barre Boulevard,  Wilkes-Barre,  Pennsylvania 18702.  Jewelcor
Management Inc. has submitted the following proposal:

         RESOLVED,  it is  recommended  that the Board of  Directors  of Niagara
Bancorp,  Inc. (the  "Company")  take the  necessary  steps to achieve a sale or
merger of the Company on terms that will maximize shareholder value.

Supporting Statement

         Based on the analysis below, Jewelcor Management,  Inc. ("JMI") believe
that the Company could  potentially  achieve an  acquisition  price of $17.13 to
$17.85 per share if the Board of Directors took the necessary steps to achieve a
sale or merger. In JMI's opinion, the following acquisition valuations provide a
reasonable  basis for  estimating a potential  acquisition  price of the Company
well in excess of the current stock price.1

Analysis

         JMI compared the  Company's  book value and earnings per share  ("EPS")
with the acquisition ratios for three of the Company's relevant peer groups: (1)
"Regional Peer Group" , (2) "Asset-Size  Peer Group" and (3) "National  Industry
Peer Group".2 Based upon summary  statistics for mergers  announced in 1999, JMI
derived the Average  Announced  Price/Book Ratio  ("Price/Book")  and the Median
Announced Price/Last Twelve Months EPS Ratio ("Price/EPS") for each of the three
peer groups.  JMI then  derived an average of the three peer groups'  respective
Price/Book ("Peer Group Average  Price/Book") and Price/EPS ("Peer Group Average
Price/EPS")  and multiplied  the applicable  Peer Group Average ratios times the
Company's  (a) book  value and (b) last  twelve  months  diluted  EPS  ("Company
EPS").3



Book Value Approach

                                                                          
         Company Stock Price (11/17/99)                                         $  10.75
         Company Book Value (9/30/99)                                               9.08
         Company Price/Book                                                       118.39%

         Peer Group Average Price/Book                                            196.59%
         COMPANY'S POTENTIAL ACQUISITION PRICE                                  $  17.85

Earnings Approach

         Company EPS(9/30/99)                                                   $   0.65


                                       16






                                                                          

         Company's Price/EPS                                                       16.54X

         Peer Group Average Price/EPS                                              26.35X
         COMPANY'S POTENTIAL ACQUISITION PRICE                                  $  17.13


- ----------------------
1.       JMI's analyses are not the only ways to predict the Company's potential
         acquisition  price.  Morever,  they  do not  reflect  the  unrecognized
         expenses  and cost  savings  associated  with a potential  transaction,
         since  expenses and cost  savings  depend,  in part,  on the overlap in
         markets and subsidiaries present in a particular transaction.
2.       "Regional  Peer Group":  All thrifts in D.C., DE, MD, NJ, NY, PA and PR
         with mergers  announced in 1999.  "Asset-Size Peer Group":  All thrifts
         with an asset range of $1 billion to $10 billion with mergers announced
         in 1999.  "National Industry Peer Group": All  publicly-traded  thrifts
         with mergers announced in 1999.
         Source: SNL Securities LC.
3.       Although  the Company  could  possibly  achieve  any of the  individual
         acquisition  ratios  achieved by the peer groups,  JMI believes that he
         most reliable method for determining potential acquisition values is to
         compare the average ratios across peer groups.

         THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE
"AGAINST" PROPOSAL 4 FOR THE FOLLOW REASONS:

         A majority  of the issued and  outstanding  shares of your  Company are
owned by Niagara  Bancorp,  MHC. As we stated in the Prospectus  (dated February
17, 1998) relating to our initial public offering  (IPO),  New York law requires
that the Mutual  Holding  Company at all times own at least 51% of the Company's
voting shares outstanding.  Accordingly,  the sale or merger of the Company that
is requested by the resolution cannot be accomplished  unless the Mutual Holding
Company converts to stock form. Under applicable banking law and regulations,  a
sale/merger  could  not take  place  for a period  of one year  thereafter.  The
conversion of the Mutual Holding Company to the stock form is not anticipated in
the near future.

         We further stated in the IPO Prospectus that one of the purposes of the
mutual holding company  structure was to enable the Company to raise  additional
capital for the expansion and diversification of our business,  without the loss
of control through a sale that often accompanies a complete  conversion to stock
form.  The mutual  holding  company  structure  thus was  intended to enable the
Company and its subsidiary  bank,  First Niagara Bank, to remain an independent,
community-oriented  provider of  financial  services and products in our Western
New York State markets.  In fact, the strategic goal of the Company is to become
the premier community bank in Western New York State.

         The  Company  has taken  numerous  steps  since the IPO to enhance  our
franchise  value  and  thereby  enhance  the value of your  investment.  In this
regard,  we have made  several bank and  non-bank,  financial  services  related
acquisitions that strengthen our competitive  position,  improve our current and
future earnings and create non-interest income for the Company. They include:

         *        Diversification and Enhancing Sources of Non-Interest Income -
                  since  the  IPO,  the  Company  has  been  actively   pursuing
                  financial  services  organizations to diversify our sources of
                  income.  We acquired two insurance  agencies and a third-party
                  administrator   in  1999  and  in  2000,   we  closed  on  the
                  acquisition of a leasing

                                       17





                  company and announced an acquisition of an investment advisory
                  firm. These  acquisitions are decreasing our dependency on net
                  interest  income and the  uncertainty  involved  with interest
                  rate changes.

         *        Expansion  of Banking  Franchise  - the  Company has also been
                  active in  expanding  its core banking  franchise  through the
                  acquisition of Albion Bancorp and  soon-to-close CNY Financial
                  in Central New York State. The Bank, the largest subsidiary of
                  the Company,  is also expanding  through its continued de novo
                  banking strategy,  including the recently opened branch in the
                  Rochester  market and the  implementation  of its PC  internet
                  banking and bill paying product.

         *        Performance - the Company's financial performance continues to
                  improve  especially  in  comparison  to other  mutual  holding
                  company   organizations  and  other  thrifts.   In  1999,  the
                  Company's  return on assets  improved  to 1.13%  form 1.07% in
                  1998,  excluding the charitable  foundation  contribution.  In
                  addition,  in light of the growth and  diversification  taking
                  place,  the  Company's  return on equity  improved to 7.52% in
                  1999  from  6.43% in 1998 as we  continue  to put the  capital
                  raised in the IPO to good use.

     As  significant  owners  in your  Company,  your  Board  of  Directors  and
management  of course is  disappointed  in the decline of the  trading  price of
Niagara  Bancorp common stock.  Although it does not diminish our resolve and to
continue to take those steps that will  enhance the  strategic  and  operational
value of your Company, we would note that the trading price of the stocks of our
peer  group,  and of  community  banks,  in  general,  have  also  significantly
declined.  We are steadfast in our belief that we are creating  long-term  value
for all of our  shareholders.  As owners of shares having a current market value
in excess of $5 million, the interests of your Board of Directors and management
are closely aligned with those of you, the stockholders.

     In  conclusion,  we do not believe that any valid purpose will be served by
voting for this  stockholder  proposal.  Your  management and Board of Directors
have  demonstrated  as a commitment  to building  franchise  value and enhancing
long-term  value for  stockholders.  For the  foregoing  reasons,  YOUR BOARD OF
DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "AGAINST" THE STOCKHOLDER PROPOSAL.
