                    RCSB FINANCIAL, INC. AND SUBSIDIARIES
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONDENSED)
                                 MAY 31, 1997
                                 (Unaudited)

1.     BASIS OF PRESENTATION

The accompanying consolidated financial statements, which include the accounts
of  RCSB Financial, Inc. and its subsidiaries (RCSB or the Company), have been
prepared  in accordance with the instructions for Form 10-Q, and therefore, do
not   include  all   information  and   footnotes  necessary  for  a  complete
presentation  of  financial  position, results of operations and cash flows in
accordance  with  generally  accepted  accounting  principles.  The  financial
statements  and the information under the heading "Management's Discussion and
Analysis  of Financial Condition and Results of Operations" are prepared under
the presumption that the interim consolidated financial statements are read in
conjunction  with  the Company's Annual Report on Form 10-K for the year ended
November 30, 1996.

In  the  opinion  of management, the unaudited, consolidated interim financial
statements  of  RCSB  Financial, Inc. and subsidiaries reflect all adjustments
(consisting of normal recurring accruals) necessary for a fair presentation of
the  statements.  The  results  of  operations  for the interim period are not
necessarily  indicative of the results of operations which may be expected for
the entire year.  For consistency among the periods presented, certain amounts
in  the  prior year's consolidated financial statements have been reclassified
to conform with the 1997 presentation.

2.     PENDING MERGER WITH CHARTER ONE FINANCIAL, INC.

On  May  21,  1997,  the  Board  of  Directors  of RCSB announced a definitive
agreement  to  merge  the  Company  with  Charter  One  Financial,  Inc.  in a
stock-for-stock  exchange.    Terms  of  the  agreement  call for the tax-free
exchange  of  0.91  shares  of  Charter  One common stock for each RCSB common
share.    The  merger,  which  is intended to be accounted for as a pooling of
interests,  is  expected  to  be  completed  in  the  fourth  quarter of 1997.
Approval  to  merge  is  required from banking regulatory authorities and both
companies'  shareholders.    In accordance with the merger agreement, RCSB has
agreed  to   abide  by  certain   covenants  regarding   operations  prior  to
consummation  of the merger.  Charter One has announced that after-tax charges
in  connection  with  the  merger  are  expected to approximate $50.0 to $60.0
million.

Concurrent  with  signing  the  definitive  merger  agreement, Charter One was
granted  an  option to purchase, under certain circumstances, 2.9 million RCSB
common  shares  at  $37.50  per  share.  Circumstances  rendering  the  option
exercisable  generally  include  (a)  actions  by RCSB designed to result in a
merger  with  or  sale  of  significant  assets  to  a  third  party,  (b) the
acquisition  of  20%  or  more  of  RCSB's  common stock by a third party, (c)
withdrawal  by  RCSB's  Board of Directors of the recommendation to merge with
Charter  One  or (d) failure of RCSB's shareholders to approve the Charter One
merger.   The option agreement carries certain other features applicable under
indicated  circumstances,  such  as  the  requirement that RCSB repurchase the
unexercised  portion  of  the  option  and securities purchased by Charter One
pursuant to the option at a specified price.

3.     ACCOUNTING CHANGES

RCSB  adopted  Financial  Accounting  Standards Board (FASB) Statement No. 121
entitled  "Accounting  for  the  Impairment  of  Long-Lived  Assets   and  for
Long-Lived  Assets  to  Be  Disposed


                                      - 8 -

<PAGE>

Of"  on December 1, 1996.  The statement requires  that long-lived  assets and
certain identifiable  intangibles to  be held   and  used  by  a  company   be
reviewed for impairment whenever events or changes  in  circumstances indicate
the    carrying      amount      of      an      asset     may     not      be
recoverable.    In  performing  the  review  for recoverability, companies are
required  to estimate the future cash flows expected to result from the use of
the  asset  and  its eventual disposition.  Under Statement 121, an impairment
loss  is  recognized  if the sum of the undiscounted future cash flows is less
than  the  carrying  amount  of  the  asset.    The statement also establishes
standards  for  recording  an  impairment  loss  for certain assets subject to
disposal.  Excluded from the scope of the statement are financial instruments,
mortgage and other loan servicing assets, deposit intangibles and deferred tax
assets.    Implementing the provisions of Statement 121 had no material impact
on the Company's consolidated financial statements on the date of adoption.

RCSB  adopted  the  disclosure requirements of FASB Statement No. 123 entitled
"Accounting for Stock-Based Compensation" effective December 1, 1996.  Related
disclosures  will  be  included  in the Company's financial statements for the
full  year  ending  November  30,  1997.   Statement 123 permits, but does not
require,  companies  to  use  a  fair-value-based  method  of  accounting  for
stock-based  compensation plans including stock options and stock appreciation
rights.   Under the fair value method, compensation cost is measured as of the
date stock awards are granted based on the value of the awards, and expense is
generally  recognized  over  the  vesting  period. Companies such as RCSB that
elect  to  continue  using  the  intrinsic-value-based method under Accounting
Principles  Board  (APB)  Opinion  No.  25,  are required to provide pro forma
disclosures  of  net  income  and  net  income  per  share in annual financial
statements  to show the effect of applying the fair-value-based method.  Under
the  intrinsic  method, compensation cost is the excess, if any, of the market
price  of the stock as of the grant date over the amount employees must pay to
acquire the stock or over the price established for determining  appreciation.
Under  RCSB's  compensation  policies, there is no such excess on the dates of
grant.

On  January  1, 1997, RCSB adopted FASB Statement No. 125 entitled "Accounting
for  Transfers  and  Servicing  of  Financial  Assets  and  Extinguishments of
Liabilities,"  which  provides   guidance  for  distinguishing   transfers  of
financial  assets  that are sales from transfers that are  secured borrowings.
The  statement  requires  the  application  of a financial-components approach
which,  following  a  transfer, results in recognizing in financial statements
the assets an entity controls and removing from financial statements assets it
no longer controls.  A transferor has surrendered control, in general, only if
the  transferred  assets  have  been legally isolated from the transferor, the
transferee  obtains the right to pledge or exchange the assets and there is no
agreement that entitles or obligates the transferor  to repurchase the assets.
Liabilities  are  eliminated  from  financial  statements  only  when they are
extinguished.    The  new standard applies to all transactions occurring after
December  31,  1996,  except those involving collateral pledges and securities
repurchase  agreements  for   which  the  rule  change  is  delayed  one year.
Application  of  the  pronouncement had no material effect on the consolidated
financial position of RCSB.

4.     CERTAIN COMMON STOCK TRANSACTIONS

Commencing  in  October  1996,  RCSB's  Board  of  Directors   authorized  the
repurchase  of  up  to  1.5   million  shares  of  the Company's common stock.
Repurchases had been terminated as a result of the pending merger with Charter
One  Financial,  Inc.    Prior  to  such  termination, 947,100 shares had been
repurchased at a cost of $28.9 million.

On June 25, 1997, the Board of Directors declared a cash dividend of $0.15 per
common  share,  payable  August  1, 1997 to shareholders of record on July 15,
1997.

5.     NET INCOME PER SHARE

Primary net income per common share amounts for the three and six months ended
May  31,  1997  and  1996  were  computed  by  dividing net income, reduced by
preferred  stock  dividends  in 1996, by the weighted average number of common
shares and, in 1997, common stock equivalents  outstanding during the periods.
The  weighted  average  number  of  common  shares utilized in the calculation
totaled  14,941,966 and 12,921,063 for the three months ended May 31, 1997 and
1996, respectively, and 15,182,961 and 13,324,966 for the six months ended May
31,  1997  and  1996,  respectively.    The  1997 second quarter and six-month
amounts  included  common  stock  equivalents  totaling  404,469  and 411,787,
respectively, relating to outstanding stock options.

Fully  diluted  net income per common share for the three and six months ended
May  31,  1997  was  computed  by  dividing net income by the weighted average
number  of  common  and  common  equivalent  shares outstanding.  For the 1996
periods,  net  income was divided by the sum of the weighted average number of
common  shares  outstanding  and the common shares issuable if all outstanding
preferred shares were converted to common at the beginning of the period.  The
weighted  average  number  of  common  shares  utilized totaled 14,998,306 and
17,590,969  for  the  three months ended  May 31, 1997 and 1996, respectively,
and  15,248,258 and 17,994,894 for the six months ended May 31, 1997 and 1996,
respectively.   Common stock equivalents of 460,809 and 477,084, respectively,
were included in the 1997 second quarter and six-month amounts.  There were no
materially dilutive common stock equivalents in 1996.

6.     RECENTLY ISSUED ACCOUNTING STANDARDS

In  February  1997,  the  FASB issued Statement No. 128 entitled "Earnings per
Share."  The  statement  revises  standards  for  computing and presenting net
income  per share by (a) replacing primary net income per share with basic net
income  per  share,  (b)  requiring dual presentation of basic and diluted net
income  per  share  for  entities  with  complex  capital  structures  and (c)
requiring  a reconciliation of the basic net income per share computation with
diluted  net  income  per  share.  Basic net income per share is calculated by
dividing  net  income available to common shareholders by the weighted-average
number  of  common  shares outstanding for the period, without considering the
dilutive effect of potentially issuable common shares.  Diluted net income per
share includes the effect of potential dilution that could occur if securities
or  other  contracts  to  issue  common stock were exercised or converted into
common  shares.    This statement is effective beginning in RCSB's 1998 fiscal
year,  and  all  prior earnings per share data will be restated at the time of
adoption.    Under the provisions of Statement 128, earnings per share for the
periods ending May 31, 1997 would be as follows.

In  June  1997,  the  FASB  issued  Statement  No.  130  entitled   "Reporting
Comprehensive  Income."  The statement establishes standards for the reporting
and  display  of  comprehensive income and its components (revenues, expenses,
gains   and  losses)  in  a  full set of general purpose financial statements.
Comprehensive  income  is  defined  as  the  change  in  equity  of a business
enterprise   during  a  period  from   transactions   and  other   events  and
circumstances  from  nonowner  sources.  The impact of adopting Statement 130,
which is effective for RCSB's 1999 fiscal year, has not been determined.

In  June  1997,  the  FASB also issued Statement No. 131 entitled "Disclosures
about  Segments  of  an  Enterprise  and  Related Information."  The statement
requires  publicly-held  companies  to  report financial and other information
about  key revenue-producing segments of the entity for which such information
is  available and is utilized by the chief operating decision maker.  Specific
information  to  be  reported for individual segments includes profit or loss,
certain  revenue  and  expense  items  and  total assets.  A reconciliation of
segment  financial information to amounts reported in the financial statements
would  be  provided.  Statement 131 is  effective for RCSB's 1998 fiscal year.
At  the  present  time,  the  effect  of  adopting  the statement has not been
determined.

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
            AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

RCSB  Financial,  Inc.  and  subsidiaries earned net income of $8.2 million or
$.55 per fully diluted share for the three months ended May 31, 1997, compared
to  $9.5  million  or  $.54  per share in the second quarter of 1996.  For the
first six months of 1997, RCSB's net income totaled $17.9 million or $1.18 per
share  compared  to  $19.2  million  or $1.07 per share in 1996.  Earnings per
fully diluted share in the 1997 second quarter and six-month periods increased
by  1.9%  and  10.3%,  respectively.  Common stock repurchases during 1996 and
1997  favorably  affected  earnings  per  share while resulting in incremental
interest  expense.    RCSB's  earnings in the three and six month periods were
affected by higher stock-based compensation costs attributable to the recently
announced  merger  and the attendant increase in market price of the Company's
common stock.

Earnings  in  the  second  quarter  were also influenced by a higher loan loss
provision  and  greater operating expenses relating to the expansion of RCSB's
lending networks.  Partially offsetting the higher level of expenditures was a
rise in mortgage banking revenues generated by a $2.2 million gain on the sale
of mortgage servicing rights.

On  May  21,  1997,  the  Board  of  Directors  of RCSB announced a definitive
agreement  to  merge  the  Company  with  Charter  One  Financial,  Inc.  in a
stock-for-stock  exchange.    Terms  of  the  agreement  call for the tax-free
exchange  of  0.91  shares  of  Charter  One common stock for each RCSB common
share.    The  merger,  which  is intended to be accounted for as a pooling of
interests,  is  expected  to  be   completed  in  the  fourth quarter of 1997.
Approval  to  merge  is  required from banking regulatory authorities and both
companies'  shareholders.    In accordance with the merger agreement, RCSB has
agreed  to  abide  by   certain  covenants   regarding   operations  prior  to
consummation  of the merger.  Charter One has announced that after-tax charges
in  connection  with  the  merger  are  expected to approximate $50.0 to $60.0
million.

Concurrent  with  signing  the  definitive  merger  agreement, Charter One was
granted  an  option to purchase, under certain circumstances, 2.9 million RCSB
common  shares  at  $37.50  per  share.  Circumstances  rendering  the  option
exercisable  generally  include  (a)  actions  by RCSB designed to result in a
merger  with  or  sale  of  significant  assets  to  a  third  party,  (b) the
acquisition  of  20%  or  more  of  RCSB's  common stock by a third party, (c)
withdrawal  by  RCSB's  Board of Directors of the recommendation to merge with
Charter  One  or (d) failure of RCSB's shareholders to approve the Charter One
merger.   The option agreement carries certain other features applicable under
indicated  circumstances,  such  as  the  requirement that RCSB repurchase the
unexercised  portion  of  the  option  and securities purchased by Charter One
pursuant to the option at a specified price.

Second Quarter Review

Net  interest  income  grew  by 1.1% to $33.4 million in the second quarter of
1997  from $33.0 million in 1996.  A 27.9% increase in average automobile loan
outstandings,  combined with a widening of the average spread between interest
rates  on  RCSB's  asset and liability portfolios, produced greater amounts of
net  interest  income.    Loan  growth was funded by higher levels of customer
deposits and repayments received on the Company's portfolio of mortgage-backed
securities.    Net  interest  income  was also affected by interest expense on
borrowings utilized by RCSB to repurchase common stock.

Automobile  loan  originations  rose  74.0%  to  $315.2  million in the second
quarter  of  1997  from  $181.1  million  in  1996.   Higher originations were
achieved  both  in  existing markets and by entering new markets.  In December
1996,  American Credit Services, Inc. (ACSI), the Company's automobile lending
subsidiary,  expanded  into  the  mid-Atlantic  market  with  the opening of a
regional  office  in  Baltimore,  Maryland.    Opportunities for expansion are
considered by ACSI on an ongoing basis.

The  growth in RCSB's overall interest rate spread to 3.43% in 1997 from 3.25%
in  1996   resulted  from   a   0.18%  increase  in  the  average   yield   on
interest-earning  assets  without  any  increase   in  the   average  rate  on
interest-bearing  liabilities.    Relatively  stable interest rates during the
past year coupled with an increase in the portion of RCSB's assets invested in
automobile  loans  have  resulted  in  the  Company's  greater overall spread.
Automobile loans, which have carried wider spreads over the cost of funds than
residential mortgage-related assets, totaled 31.5% of average interest-earning
assets  in  the  second  quarter of 1997, up from 24.6% in 1996.  Net interest
margin,  which  is  influenced  by  the  overall  interest rate spread and the
relationship  of  interest-earning  asset  volumes  to  interest-bearing
liabilities, rose to 3.56% in 1997 from 3.52% in 1996.

The  following  table  presents information for the second quarter of 1997 and
1996  regarding interest yields and rates, average earning asset and liability
volumes,  and  the allocation of interest variations between amounts caused by
volumes and amounts attributable to rates.  No tax equivalent adjustments have
been made for minor amounts of tax-exempt income earned by RCSB.

RCSB's  provision  for  loan  losses was $4.1 million in the second quarter of
1997,  compared to $3.5 million in the prior year.  The increased provision in
1997  was  primarily  due to growth in the automobile loan portfolio resulting
from  higher volumes of loan originations in the quarter, and higher levels of
auto  loan charge offs.  Nationwide trends in the collection of consumer loans
have  affected  the Company's automobile loan portfolio, resulting in somewhat
higher  delinquencies  and  charge  offs  compared  with  the year ago period.
Delinquency  trends  in the Company's automobile loan portfolio have improved,
however, since the first quarter of 1997.


                                      -14-

<PAGE>

Also affecting the loan loss allowance in the second quarter was the sale of a
significant  portion  of  RCSB's  remaining commercial loan portfolio.  In May
1997,  the  Company sold $41.3 million of performing commercial mortgage loans
for  a  loss  of  $0.3  million,  after  deducting  $2.0  million of allocated
allowances from carrying value.  At May 31, 1997, RCSB allocated $18.9 million
of  its  allowance  for  loan  losses  to automobile loans and $1.6 million to
commercial  loans,  representing  1.52%   and  12.70%,  respectively,  of  the
outstanding loan portfolios.

The  adequacy of the Company's loan loss allowance is evaluated quarterly with
consideration  given  to  the  status  of  particular  loans, the general risk
characteristics  of the loan portfolio, historical charge-offs and recoveries,
the  regulatory  environment,  current  appraisals  and  economic  and  market
conditions.    As  of  May  31, 1997, RCSB's allowance for loan losses totaled
$26.3  million  or 104.2% of nonperforming loans, compared to $28.2 million or
116.7%  of  nonperforming  loans  at  November  30, 1996.  The average for all
publicly-held  thrift  institutions  was  approximately 72% as of December 31,
1996.

Mortgage  banking  noninterest  income  totaled  $13.9  million  in the second
quarter  of  1997,  compared  to $12.1 million in 1996.  The increase resulted
from  a  pretax  gain  of  $2.2  million generated by the sale of servicing on
$838.3  million  of  residential  mortgage  loans,  partially  offset by lower
revenue  from  the  sales  of loans originated for sale.  Residential mortgage
loan  originations  at  American  Home  Funding,  Inc.  (AHF), RCSB's mortgage
banking  subsidiary,  were  $419.0 million during the second quarter, slightly
lower than $421.6 million in the prior year. AHF's portfolio of loans serviced
for  others declined to $7.6 billion at May 31, 1997, compared to $9.0 billion
at November 30, 1996 and $9.4 billion at May 31, 1996.

RCSB's  retail  banking  unit,  Rochester  Community  Savings  Bank, generated
noninterest  income of $2.1 million in the second quarter of 1997, compared to
$2.7  million  in 1996.  The decrease in revenue relates to the September 1996
transfer  of  securities  brokerage  activities  to an independent third party
which  offers  securities  products and services through RCSB's retail banking
offices.  Earnings  in  this  category  represent  fees  and  service  charges
collected  for  various  deposit-related  activities, revenues from the bank's
insurance  sales  operation  and  prior  to  September  1996, commissions from
securities brokerage activities. Deposit-related fees and service charges rose
by  $0.2  million in the 1997 quarter due to the Company's continued expansion
in  the  Buffalo,  New  York  market.  One branch office was opened during the
first  quarter  of  1997, and in June 1997, RCSB opened two additional offices
bringing  the  total  number  in Buffalo to 17.  Revenues from insurance sales
activities  increased  by  $0.2  million in 1997 due to greater sales of fixed
annuity products.

Automobile  loan banking noninterest income was less than $0.1 million for the
second  quarter  of 1997, compared to $1.1 million in 1996.  While ACSI earned
loan servicing fees in 1996 from securitized automobile loans owned by others,
the securities matured in 1996.

There were no gains or losses from securities sales in the 1997 second quarter
compared  to $1.0 million in 1996.  RCSB sold $59.5 million of mortgage-backed
securities  from  the  available-for-sale  portfolio  in  1996  in response to
interest rate-related market opportunities.

Operating  expenses  in the second quarter of 1997 were $32.5 million compared
to $31.9 million in the prior year. The increase was primarily attributable to
higher  expenses  associated with the expansion of lending networks at AHF and
ACSI  and  incremental  accruals  for stock-based compensation costs resulting
from  a  21.7%  increase  in  RCSB's  stock  price  in the 1997 quarter. These
expenses  were  partially  offset  by  a  reduction  in  the  cost of carrying
foreclosed real estate.


                                      -15-

<PAGE>

The  Company's  effective  tax  rate  was 34.5% in the second quarter of 1997,
compared  to  35.0%  in  1996.    Reductions  in RCSB's deferred tax valuation
allowance  during  both  years  were  the  largest  factors accounting for the
difference from normal rates of approximately 41.0%.

Six Month Review

For  the  first  six  months  of  1997,  RCSB's  net interest income was $65.6
million,  compared  to  $64.7  million  in  the  prior year.  The increase was
largely  due  to  a  25.5%  rise in average automobile loans outstanding and a
wider  average  interest  rate  spread.   Automobile loan originations for the
first six months of 1997 totaled $489.5 million, up 51.9% from the prior year.
RCSB's  interest  rate  spread  climbed  to  3.31% in 1997 from 3.12% in 1996,
primarily  due to a widening of general marketplace spreads between short-term
and  intermediate-term  interest  rates  and  an increase in the percentage of
RCSB's  assets invested in automobile loans.  Net interest margin was 3.51% in
both 1997 and 1996.

The  following table presents information regarding interest yields and rates,
average  earning  asset  and liability volumes, and the allocation of interest
variations between amounts caused by volumes and amounts attributable to rates
for the six months ended May 31, 1997 and 1996.  No tax equivalent adjustments
have been made for minor amounts of tax-exempt income earned by RCSB.

RCSB's  provision for loan losses totaled $8.1 million in the first six months
of  1997  compared  to  $6.2  million  in 1996.  Growth in the automobile loan
portfolio  and  higher  charge off levels produced a corresponding requirement
for  greater  loan  loss  provisions.    Partially  offsetting the increase in
automobile  loan  provisions  was  a  decrease  in requirements for commercial
mortgage allowances due to the reduced size of the portfolio.

Mortgage  banking  noninterest  income was $29.9 million in 1997 up 33.6% from
$22.4  million  in  the prior year.  The increase is primarily attributable to
two  sales  of  servicing  on residential mortgage loans which produced pretax
gains totaling $5.8 million.  Residential mortgage originations at AHF totaled
$741.0 million during the first six months of 1997, compared to $748.8 million
in 1996.

<PAGE>

Retail  banking  fees  and  service charges earned for various deposit-related
activities  grew by $0.4 million in the first six months of 1997.  The overall
decline  in  retail  banking  noninterest  income  resulted from the late 1996
transfer  of  RCSB's  securities  brokerage  business  to an independent third
party.    In  1997,  the  Company  receives  expense  reimbursements  from the
independent third party which operates in RCSB's banking offices.

Operating  expenses  incurred  during  the first six months of 1997 were $62.7
million  compared  to $59.1 million in the prior year.  Higher expenses at AHF
and ACSI, resulting from the expansion of loan origination networks, and costs
associated with stock-based compensation were partially offset by a decline in
other real estate expenses.

The  Company's  effective  tax  rate  was 37% in 1997 compared to 35% in 1996,
reflecting  reductions  in  the  deferred  tax valuation allowance during both
years.


FINANCIAL CONDITION

At  May  31,  1997,  RCSB's  total assets were $4.10 billion compared to $4.01
billion  at  November  30,  1996.  Loans at the end of the 1997 second quarter
totaled  $2.20 billion compared to $2.02 billion at November 30, 1996.  Growth
in  the automobile loan portfolio, which increased to $1.24 billion at May 31,
1997  from  $994.7  million  at the end of the 1996 fiscal year, was partially
offset  by a decrease in residential mortgage loans and the sale of commercial

Allowance for Loan Losses and Nonperforming Assets

The  determination  of  the  allowance  for  loan  losses  is based on ongoing
analyses  of  the loan portfolio and reflects an amount which, in management's
judgment,  is  adequate to provide for potential losses. While management used
all  currently  available  information  to  determine   the  adequacy  of  the
allowance,  future additions may be necessary based on changes in economic and
market  conditions, possible changes in strategies for resolving problem loans
and  specific  borrower situations.  In addition, various regulatory agencies,
as  an  integral  part  of  the  examination  process, periodically review the
Company's  allowance  for  losses  on  loans.    Such agencies may require the
Company to recognize additions to the allowance based on their judgments about
information available at the time of their examinations.  RCSB's allowance for
loan  losses  at  May  31,  1997  equaled 104.2% of nonperforming loans, which
exceeded  the average of approximately 72% for all publicly-held thrifts as of
December  31,  1996,  the  most  recent  date  for  which  such information is
available.  Activity in RCSB's loan loss allowance during the first six months
of  1997  and  1996 and the allocation of the allowance for loan losses at May
31, 1997 and November 30, 1996 are presented below.

                 AGREEMENT AND PLAN OF MERGER AND REORGANIZATION
                 -----------------------------------------------

         THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION (this
"Agreement") dated May 21, 1997, is by and among Charter One Financial, Inc., a
Delaware corporation ("COFI"), Charter-Michigan Bancorp, Inc., a Michigan
corporation and a wholly owned first-tier subsidiary of COFI ("Charter
Michigan"), Charter One Bank F.S.B., a federally chartered savings bank and a
wholly owned subsidiary of Charter Michigan ("Charter One Bank"), RCSB
Financial, Inc., a Delaware corporation ("RCSB"), and Rochester Community
Savings Bank, a New York chartered savings bank and a wholly owned first-tier
subsidiary of RCSB ("Target Bank").

         A. COFI, Charter Michigan, Charter One Bank, RCSB and Target Bank wish
to provide for the terms and conditions of a strategic alliance in which RCSB
will be merged ("Company Merger") with and into Charter Michigan, followed
immediately by the merger of Target Bank with and into Charter One Bank ("Bank
Merger"). The Company Merger and the Bank Merger are collectively referred to
herein as the "Merger."

         B. For federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended ("Code"), and this Agreement shall
constitute a plan of reorganization pursuant to Section 368 of the Code.

         C. For accounting purposes, it is intended that the Merger shall be 
accounted for as a pooling of interests.

         D. The parties hereto desire to make certain representations, 
warranties, covenants and agreements in connection with the Merger and also to
prescribe various conditions to the Merger.

         E. As a condition to and inducement for COFI, Charter Michigan, and
Charter One Bank to enter into this Agreement, COFI and each of the directors of
RCSB will concurrently with the execution and delivery of this Agreement enter
into voting agreements in the form attached hereto as Exhibit A ("Voting
Agreements") and COFI and RCSB are entering into immediately after the execution
of this Agreement a stock option agreement dated as of the date hereof in the
form attached hereto as Exhibit B ("Stock Option Agreement") pursuant to which
RCSB shall grant to COFI an option to purchase shares of RCSB's common stock.

         Accordingly, and in consideration of the representations, warranties,
covenants, agreements and conditions herein contained, the parties hereto agree
as follows:

                         THE MERGER AND RELATED MATTERS

         1.1 MERGER; SURVIVING CORPORATION AND RESULTING INSTITUTION. Subject to
the terms and conditions of this Agreement, and pursuant to the provisions of
the Michigan Business Corporation Act ("MBCA"), the Delaware General Corporation
Law ("DGCL"), the Federal Deposit Insurance Act ("FDIA"), the Home Owners' Loan
Act, as amended ("HOLA") and the rules and regulations promulgated under HOLA
and by the New York State Banking Department ("Thrift Regulations"), (a) at the
Effective Time (as defined in Section 1.2 hereof), RCSB shall be merged with and
into Charter Michigan pursuant to the terms and conditions set forth herein and
(b) thereafter at the Bank Merger Effective Time (as defined in Section 1.2
hereof), Target Bank shall be merged with and into COFI Bank pursuant to the
terms and conditions set forth herein. Upon the consummation of the Company
Merger, the separate corporate existence of RCSB shall cease and Charter
Michigan shall continue as the surviving corporation under the laws of the State
of Michigan. Upon consummation of the Bank Merger, the separate corporate
existence of Target Bank shall cease and Charter One Bank shall continue as the
resulting institution. The name of Charter Michigan as the surviving corporation
of the Company Merger shall remain "Charter Michigan Bancorp, Inc". From and
after the Effective Time, Charter Michigan, as the surviving corporation of the
Company Merger, shall possess all of the properties and rights and be subject to
all of the liabilities and obligations of Charter Michigan and RCSB, all as more
fully described in the MBCA and DGCL. The name of Charter One Bank, as the
resulting institution of the Bank Merger, shall remain "Charter One Bank
F.S.B.". From and after the Bank Merger Effective Time, Charter One Bank, as the
resulting institution of the Bank Merger, shall possess all of the properties
and rights and be subject to all of the liabilities and obligations of Charter
One Bank and Target Bank (including any liquidation account of Target Bank
established in connection with its conversion from mutual to stock form), all as
more fully described in the Thrift Regulations.

         1.2 EFFECTIVE TIME OF THE MERGER. As soon as practicable after each of
the conditions set forth in Article VI hereof have been satisfied or waived, the
parties will file, or cause to be filed, with the Secretary of State of
Delaware, the Michigan Department of Commerce, the Office of Thrift Supervision
("OTS") and the New York State Banking Department ("Department") such
certificates of merger, articles of combination and other documents as they may
deem necessary or appropriate for the Company Merger and the Bank Merger, which
certificates of merger, articles of combination and other documents shall in
each case be in the form required by and executed in accordance with the
applicable provisions of the DGCL, MCBA and Thrift Regulations, respectively.
The Company Merger shall become effective at the time the certificate(s) of
merger for such merger are filed with the Secretary of State of Delaware and the
Michigan Department of Commerce ("Effective Time"). The Bank Merger shall become
effective at the time the articles of combination for such merger are endorsed
by the Secretary of the OTS pursuant to the Thrift Regulations ("Bank Merger
Effective Time"). The parties shall cause the Company Merger to become effective
immediately prior to the Bank Merger.

         1.3      COMPANY MERGER.

                  (a)      CONVERSION OF RCSB STOCK.  At the Effective Time:

                           (i) Each share of common stock of RCSB, $1.00 par
                  value per share (the "RCSB Common Stock"), issued and
                  outstanding immediately prior thereto shall, by virtue of the
                  Company Merger and without any action of the part of the
                  holder thereof, but subject to Section 1.3(d) hereof, be
                  converted into the right to receive from COFI .91 shares
                  ("Exchange Ratio") of common stock of COFI, par value $.01 per
                  share ("COFI Common Stock"), including the corresponding
                  number of rights associated with the COFI Common Stock
                  pursuant to the Rights Agreement dated November 20, 1989, as
                  amended on May 26, 1995, between COFI and The First National
                  Bank of Boston as Rights Agent. If, subsequent to the date of
                  this Agreement but prior to the Effective Time, the
                  outstanding shares of COFI Common Stock shall, through a
                  reclassification, recapitalization, stock dividend, stock
                  split or reverse stock split have been increased, decreased,
                  changed into or exchanged for a different number or kind of
                  shares or securities, appropriate adjustment will be made to
                  the Exchange Ratio.

                           Notwithstanding any other provision of this
                  Agreement, any shares of RCSB Common Stock issued and
                  outstanding immediately prior to the Effective Time which are
                  then owned beneficially or of record by COFI, Charter
                  Michigan, Charter One Bank, RCSB, Target Bank or by any direct
                  or indirect Subsidiary (as hereinafter defined) of any of them
                  or held in the treasury of RCSB (other than any shares of RCSB
                  Common Stock held (A) directly or indirectly in trust
                  accounts, managed accounts and the like, or otherwise held in
                  a fiduciary capacity, that are beneficially owned by third
                  parties or (B) in respect of a debt previously contracted)
                  shall, by virtue of the Company Merger, be canceled without
                  payment of any consideration therefor and without any
                  conversion thereof.

                           (ii) Each share of Charter Michigan common stock
                  issued and outstanding or held in treasury immediately prior
                  to the Effective Time shall remain issued and outstanding or
                  held in treasury and continue to be an identical issued and
                  outstanding or treasury share of Charter Michigan common stock
                  after the Effective Time.

                           (iii) The holders of certificates representing shares
                  of RCSB Common Stock shall cease to have any rights as
                  stockholders of RCSB, except such rights, if any, as they may
                  have pursuant to the DGCL. Except as provided above, until
                  certificates representing shares of RCSB Common Stock are
                  surrendered for exchange, the certificates shall, after the
                  Effective Time, represent for all purposes only the right to
                  receive the number of whole shares of COFI Common Stock into
                  which such shares of RCSB Common Stock shall have been
                  converted by the

                                       3

<PAGE>



                  Company Merger as provided above and the right to receive the
                  cash value of any fraction of a share of COFI Common Stock as
                  provided below (collectively, the "Merger Consideration").

                  (b) RESERVATION OF SHARES. Prior to the Effective Time, the
                  Board of Directors of COFI shall reserve for issuance a
                  sufficient number of shares of COFI Common Stock for the
                  purpose of issuing its shares to the stockholders of RCSB
                  in accordance herewith.

                  (c) EXCHANGE OF RCSB COMMON STOCK.

                           (i) As soon as reasonably practicable after the
                  Effective Time, holders of record of certificates formerly
                  representing shares of RCSB Common Stock ("Certificates")
                  shall be instructed to tender such Certificates to COFI, or at
                  the election of COFI, to an independent exchange agent to be
                  selected by COFI (the "Exchange Agent") pursuant to a letter
                  of transmittal that COFI shall deliver or cause to be
                  delivered to such holders. Such letter of transmittal shall
                  specify that delivery shall be effected, and risk of loss and
                  title to Certificates shall pass, only upon acceptance of such
                  Certificates by COFI or the Exchange Agent.

                           (ii) After the Effective Time, each holder of a
                  Certificate that properly surrenders such Certificate to COFI
                  or the Exchange Agent, together with a properly completed
                  letter of transmittal, duly executed, will, upon acceptance
                  thereof by COFI or the Exchange Agent, be entitled to the
                  Merger Consideration payable in respect of the shares
                  represented thereby, and the Certificates so surrendered shall
                  forthwith be cancelled.

                           (iii) COFI or the Exchange Agent shall accept
                  Certificates upon compliance with such reasonable terms and
                  conditions as COFI or the Exchange Agent may impose to effect
                  an orderly exchange thereof in accordance with customary
                  exchange practices. Certificates shall be appropriately
                  endorsed or accompanied by such instruments of transfer as
                  COFI or the Exchange Agent may reasonably require.

                           (iv) Each outstanding Certificate shall until duly
                  surrendered to COFI or the Exchange Agent be deemed to
                  evidence the right to receive the Merger Consideration.

                           (v) After the Effective Time, holders of Certificates
                  shall cease to have rights with respect to the RCSB Common
                  Stock previously represented by such Certificates, and their
                  sole rights shall be to exchange such Certificates for the
                  Merger Consideration. At the Effective Time, RCSB shall
                  deliver a certified copy of a list of its stockholders to COFI
                  or the Exchange Agent. After the Effective Time, there shall
                  be no further transfer on the records of RCSB of Certificates,
                  and

<PAGE>



                  if such Certificates are presented to RCSB for transfer, they
                  shall be canceled against delivery of the Merger
                  Consideration. COFI shall not be obligated to deliver the
                  Merger Consideration to any holder of RCSB Common Stock until
                  such holder surrenders the Certificates as provided herein. No
                  dividends declared will be remitted to any person entitled to
                  receive COFI Common Stock under this Agreement until such
                  person surrenders the Certificate representing the right to
                  receive such COFI Common Stock, at which time such dividends
                  on whole shares of COFI Common Stock with a record date on or
                  after the Effective Time shall be remitted to such person,
                  without interest and less any taxes that may have been imposed
                  thereon. Certificates surrendered for exchange by any person
                  constituting an "affiliate" of RCSB for purposes of Rule 145
                  under the Securities Act of 1933 and the rules and regulations
                  thereunder (the "Securities Act") shall not be exchanged for
                  certificates representing COFI Common Stock until COFI has
                  received a written agreement from such person as specified in
                  Section 5.3. Neither the Exchange Agent nor any party to this
                  Agreement nor any affiliate thereof shall be liable to any
                  holder of RCSB Common Stock represented by any Certificate for
                  any consideration paid to a public official pursuant to
                  applicable abandoned property, escheat or similar laws. COFI
                  and the Exchange Agent shall be entitled to rely upon the
                  stock transfer books of RCSB to establish the identity of
                  those persons entitled to receive consideration specified in
                  this Agreement, which books shall be conclusive with respect
                  thereto. In the event of a dispute with respect to ownership
                  of stock represented by any Certificate, COFI or the Exchange
                  Agent shall be entitled to deposit any consideration in
                  respect thereof in escrow with an independent third party and
                  thereafter be relieved with respect to any claims thereto.

                           (vi) If the Merger Consideration is to be issued to a
                  person other than a person in whose name a surrendered
                  Certificate is registered, it shall be a condition of issuance
                  that the surrendered Certificate shall be properly endorsed or
                  otherwise in proper form for transfer and that the person
                  requesting such issuance shall pay to COFI or the Exchange
                  Agent in advance any required transfer or other taxes or
                  establish to the satisfaction of COFI or the Exchange Agent
                  that such tax has been paid or is not applicable.

                           (vii) In the event any Certificate shall have been
                  lost, stolen or destroyed, the owner of such lost, stolen or
                  destroyed Certificate shall deliver to COFI or the Exchange
                  Agent an affidavit stating such fact, in form satisfactory to
                  COFI, and, at COFI's discretion, a bond in such reasonable sum
                  as COFI or the Exchange Agent may direct as indemnity against
                  any claim that may be made against COFI or RCSB or its
                  successor or any other party with respect to the Certificate
                  alleged to have been lost, stolen or destroyed. Upon such
                  delivery, the owner shall have the right to receive the Merger
                  Consideration with respect to the shares represented by the
                  lost, stolen or destroyed Certificate.

                                        5

                  (d) NO FRACTIONAL SHARES. Notwithstanding any other provision
         of this Agreement, neither certificates nor scrip for fractional shares
         of COFI Common Stock shall be issued in the Company Merger. Each holder
         who otherwise would have been entitled to a fraction of a share of COFI
         Common Stock (after taking into account all Certificates delivered by
         such holder) shall receive in lieu thereof cash (without interest) in
         an amount determined by multiplying the fractional share interest to
         which such holder would otherwise be entitled by the COFI Share Price
         on the last trading day preceding the Effective Time. The "COFI Share
         Price" shall mean the closing sale price (rounded down to the nearest
         cent) of one share of COFI Common Stock as reported on the Nasdaq
         National Market. No such holder shall be entitled to dividends, voting
         rights or any other rights in respect of any fractional share interest.

                  (e) STOCK OPTIONS. The Target Bank 1986 Stock Option Plan
         ("1986 Option Plan") and the Target Bank 1992 Stock-Based Compensation
         Plan ("1992 Option Plan") and each option granted thereunder
         outstanding on the date hereof (together with mandatory grants required
         to be made to non-employee directors on May 28, 1997 under the 1992
         Option Plan) and remaining outstanding immediately prior to the
         Effective Time shall, at the Effective Time, be assumed by COFI and
         each such option shall continue to be outstanding, but shall represent
         an option to purchase shares of COFI Common Stock in an amount and at
         an exercise price determined as provided below (and otherwise subject
         to the terms of the 1986 Option Plan or 1992 Option Plan, whichever is
         applicable):

                           (i) the number of shares of COFI Common Stock to be
                  subject to the continuing option shall be equal to the product
                  of the number of shares of RCSB Common Stock subject to the
                  original option and the Exchange Ratio, provided that any
                  fractional share of COFI Common Stock resulting from such
                  multiplication shall be rounded down to the nearest share; and

                           (ii) the exercise price per share of COFI Common
                  Stock under the continuing option shall be equal to the
                  exercise price per share of RCSB Common Stock under the
                  original option divided by the Exchange Ratio, provided that
                  such exercise price shall be rounded down to the nearest cent.

                  It is intended that the foregoing assumption shall be
         undertaken consistent with and in a manner that will not constitute a
         "modification" under Section 424 of the Code as to any option which is
         an "incentive stock option".

                  (f) ARTICLES OF INCORPORATION AND BYLAWS OF THE SURVIVING
         CORPORATION. The Articles of Incorporation and Bylaws of Charter
         Michigan, as in effect immediately prior to the Effective Time, shall
         be the Articles of Incorporation and Bylaws of Charter Michigan, as the
         surviving corporation of the Company Merger, until either is thereafter
         amended in accordance with applicable law.

         Michigan, as the surviving corporation of the Company Merger, consents
         to be sued and served with process in the State of Delaware and
         irrevocably appoints the Secretary of State of Delaware as its agent to
         accept service of process in any proceeding in the State of Delaware to
         enforce against it any obligation of RCSB.

                  (i) PRINCIPAL OFFICE.  The location of the principal office of
         Charter Michigan, as the surviving corporation of the Company Merger,
         in the State of Michigan is 13606 Michigan Avenue, 2nd Floor,
         Dearborn, Michigan 48126.

         1.4      BANK MERGER.

                  (a) CANCELLATION OF TARGET BANK COMMON STOCK. At the Bank
         Merger Effective Time, each share of common stock of Target Bank
         ("Target Bank Common Stock") issued and outstanding immediately prior

         of capital stock or other securities or obligations of Charter One Bank
         shall be issued with respect to or in exchange for such canceled
         shares, and such canceled shares of Target Bank Common Stock shall not
         be converted into capital stock or other securities or obligations of
         Charter One Bank.

change to be desirable, provided, however, that no such change shall (a) alter
or change the amount or kind of the Merger Consideration or the treatment of
stock options as set forth in Section 1.3(e) hereof, (b) diminish the benefits

made in connection with this Agreement, (c) materially impede or delay the
consummation of the Company Merger (d) adversely affect the tax treatment of

                                   ARTICLE II

           REPRESENTATIONS AND WARRANTIES OF COFI AND CHARTER ONE BANK

         COFI and Charter One Bank jointly and severally represent and warrant
to RCSB and Target Bank that:

         2.1      ORGANIZATION.

                  (a) COFI is a corporation duly organized, validly existing and
         in good standing under the laws of the State of Delaware and has all
         requisite power and authority, corporate and otherwise, to own, operate
         and lease its assets and properties and to carry on its business
         substantially as it is now being conducted. COFI is duly licensed or
         qualified to do business and is in good standing in each jurisdiction
         where the character of the assets or properties owned or leased by it
         or the nature of the business transacted by it requires that it be so
         licensed or qualified, except where the failure to be so licensed or
         qualified would not have a Material Adverse Effect (as defined in
         Section 2.1(b) hereof)) on COFI or its ability to consummate the
         transactions contemplated herein. COFI has all requisite corporate
         power and authority to enter into this Agreement and, subject to the
         approval of this Agreement and the Company Merger by its stockholders
         and the receipt of all requisite regulatory approvals and the
         expiration of applicable waiting periods, to

                                        8

         consummate the Merger.  COFI is duly registered as a savings and loan 
         holding company under HOLA.

                  (b) As used in this Agreement, the term "Material Adverse
         Effect" with respect to COFI or RCSB means any condition, event, change
         or occurrence that has or may reasonably be expected to have a material
         adverse effect on the condition (financial or otherwise), properties,
         business, operations, results of operations, assets or deposit
         liabilities of such entity on a consolidated basis; it being understood
         that a Material Adverse Effect shall not include: (i) a change with
         respect to, or effect on, such entity and its Subsidiaries resulting
         from a change in law, rule, regulation, generally accepted accounting
         principles or regulatory accounting principles, as such would apply to
         the financial statements of such entity on a consolidated basis; (ii) a
         change with respect to, or effect on, such entity and its Subsidiaries
         resulting from expenses (such as legal, accounting and investment
         bankers' fees) incurred in connection with this Agreement; (iii) a
         change with respect to, or effect on, such entity and its Subsidiaries
         resulting from any other matter affecting depository institutions
         generally including, without limitation, changes in general economic
         conditions and changes in prevailing interest and deposit rates; or
         (iv) in the case of RCSB, any financial change resulting from
         adjustments taken pursuant to Section 4.1(h) hereof.

         2.2 AUTHORIZATION. The execution, delivery and performance of this
Agreement and the consummation of the transactions contemplated hereby have been
duly approved and authorized by the Boards of Directors of COFI, Charter
Michigan and Charter One Bank, and all necessary corporate action on their part
has been taken, subject to the approval of this Agreement and the Company Merger
by the holders of a majority of the issued and outstanding COFI Common Stock.
This Agreement has been duly executed and delivered by COFI, Charter Michigan
and Charter One Bank and constitutes the valid and binding obligation of each of
them and is enforceable against each of them, except to the extent that
enforceability thereof may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws or equitable principles and
doctrines.

         2.3 CONFLICTS. Subject to the second sentence of this Section 2.3, the
execution and delivery of this Agreement does not, and the consummation of the
transactions contemplated hereby will not, conflict with or result in any
violation, breach or termination of, or default or loss of a material benefit
under, or permit the acceleration of any obligation under, or result in the
creation of any material lien, charge or encumbrance on any of the property or
assets under, any provision of the Certificate of Incorporation or Bylaws of
COFI or similar documents of any COFI Subsidiary or any mortgage, indenture,
lease, agreement or other instrument, permit, concession, grant, franchise,
license, judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to COFI or any COFI Subsidiary or their respective properties, other
than any such conflicts, violations or defaults which (i) will be cured or
waived prior to the Effective Time; (ii) are not material to the conduct of
business or operations of COFI or any COFI Subsidiary; or (iii) are disclosed in
Section 2.3 of that certain confidential writing delivered by

"moratorium," "control share" or other state anti-takeover statute or regulation
(i) prohibits or restricts the ability of COFI or Charter Michigan to perform
its obligations under this Agreement or its ability to consummate the
transactions contemplated hereby, (ii) would have the effect of invalidating or
voiding this Agreement or any provision hereof, or (iii) would subject RCSB to
any material impediment or condition in connection with the exercise of any of
its rights under this Agreement.

         2.5      CAPITALIZATION.

                  (a) As of the date hereof, the authorized capital stock of
         COFI consists of (i) 180,000,000 shares of COFI Common Stock, $0.01 par
         value per share, of which, as of February 28, 1997, 46,330,703 shares
         were issued and outstanding and (ii) 20,000,000 shares of preferred
         stock, $0.01 par value per share, of which none are issued and
         outstanding. All of the issued and outstanding shares of COFI Common
         Stock have been, and all of the shares of COFI Common Stock to be
         issued in the Company Merger will be, at the Effective Time, duly and
         validly authorized and issued, and are or will be, as the case may be,
         fully paid and non-assessable. None of the outstanding shares of COFI
         Common Stock has been issued in violation of any preemptive rights of
         the current or past stockholders of COFI and none of the outstanding
         shares of COFI Common Stock is or will be entitled to any preemptive
         rights in respect of the Company Merger or any of the other
         transactions contemplated by this Agreement.

                  (b) As of April 30, 1997, COFI does not have outstanding any
         securities or rights convertible into or exchangeable for COFI Common
         Stock or any commitments, contracts, understandings or arrangements by
         which COFI is or may be bound to issue

                                       10


<PAGE>



         additional shares of COFI Common Stock, except pursuant to an Agreement
         and Plan of Merger and Reorganization with Haverfield Corporation and
         Home Bank, F.S.B. dated April 22, 1997 ("Haverfield Definitive
         Agreement"), employee and director stock options or as otherwise set
         forth in Section 2.5 of the COFI Disclosure Schedule.

         2.6 COFI FINANCIAL STATEMENTS; MATERIAL CHANGES. COFI has heretofore
delivered to RCSB its audited consolidated financial statements for calendar
years ended December 31, 1996 and December 31, 1995 (together the "COFI
Financial Statements"). The COFI Financial Statements (x) are true and correct
in all material respects; (y) have been prepared in accordance with generally
accepted accounting principles applied on a consistent basis during the periods
involved (except as may be indicated in the notes thereto); and (z) fairly
present the consolidated financial position of COFI as of the dates thereof and
the consolidated results of its operations, shareholders' equity, cash flows and
changes in financial position for the periods then ended. Since December 31,
1996 to the date hereof, COFI and the COFI Subsidiaries have not undergone or
suffered any changes in their respective condition (financial or otherwise),
properties, business or operations which have been, in any case or in the
aggregate, materially adverse to COFI on a consolidated basis except as
disclosed in Section 2.6 of the COFI Disclosure Schedule. No facts or
circumstances have been discovered from which it reasonably appears that there
is a significant risk and reasonable probability that COFI will suffer or
experience a Material Adverse Effect.

         2.7      COFI SUBSIDIARIES.

                  (a) All of the COFI Subsidiaries as of the date of this
         Agreement are listed in Section 2.7 of the COFI Disclosure Schedule.
         COFI owns directly or indirectly all of the issued and outstanding
         shares of capital stock of the COFI Subsidiaries. No capital stock of
         any of the COFI Subsidiaries is, or may become required to be, issued
         (other than to COFI or another COFI Subsidiary) by reason of any
         options, warrants, scrip, right to subscribe to, calls, or commitments
         of any character whatsoever relating to, or securities or rights
         convertible into or exchangeable for, shares of the capital stock of
         any COFI Subsidiary. All of the shares of capital stock of each COFI
         Subsidiary held by COFI or a COFI Subsidiary are fully paid and
         non-assessable and are owned free and clear of any claim, lien or
         encumbrance, except as disclosed in Section 2.7 of the COFI Disclosure
         Schedule.

                  (b) Each COFI Subsidiary is either a savings bank or a
         corporation and is duly organized, validly existing and in good
         standing under the laws of the jurisdiction in which it is incorporated
         or organized, and is duly licensed or qualified to do business and is
         in good standing in each jurisdiction where the character of the assets
         or properties owned or leased by it or the nature of the business
         transacted by it requires it to be so licensed or qualified, except
         where the failure to be so licensed or qualified, either individually
         or in the aggregate, would not have a Material Adverse Effect on COFI
         or the ability of Charter Michigan or Charter One Bank to consummate
         the transactions contemplated herein.

                                       11


<PAGE>



         Each COFI Subsidiary has the corporate power and authority necessary
         for it to own, operate or lease its assets and properties and to carry
         on its business as it has been and is now being conducted.

                  (c) For purposes of this Agreement, an "COFI Subsidiary" or a
         "Subsidiary" of COFI shall mean each corporation, savings bank and
         other entity in which COFI owns or controls directly or indirectly 10%
         or more of the outstanding equity securities; provided, however, there
         shall not be included any such entity acquired in good faith through
         foreclosure, or any such entity to the extent that the equity
         securities of such entity are owned or controlled in a bona fide
         fiduciary capacity.

                  (d) Charter One Bank is a member in good standing of the
         Federal Home Loan Bank System. All eligible deposit accounts issued by
         Charter One Bank are insured by the Federal Deposit Insurance
         Corporation ("FDIC") through the Savings Association Insurance Fund
         ("SAIF") to the full extent permitted under applicable law. Charter One
         Bank is, and at all times since June 1, 1990 has been, a "domestic
         building and loan association" as defined in Section 7701(a)(19) of the
         Code and a "qualified thrift lender" as defined in Section 10(m) of
         HOLA.

         2.8 COFI FILINGS. COFI has previously made available, or will make
available prior to the Effective Time, to RCSB true and correct copies of its
(i) proxy statements relating to all meetings of its stockholders (whether
special or annual) during calendar years 1995, 1996, and 1997 and (ii) all other
reports, as amended, or filings, as amended, required to be filed under the
Securities Exchange Act of 1934, as amended (the "Exchange Act") by COFI with
the SEC since January 1, 1995, including without limitation on Forms 10-K, 10-Q
and 8-K.

         2.9 COFI REPORTS. Each of COFI and the COFI Subsidiaries has filed, and
will continue to file, all material reports and statements, together with any
amendment required to be made with respect thereto, that it was, or will be
required to file with the SEC, the FDIC, the OTS, the National Association of
Securities Dealers, Inc. ("NASD") and other applicable thrift, securities and
other regulatory authorities (except filings which are not material). As of
their respective dates (and without giving effect to any amendments or
modifications filed after the date of this Agreement with respect to reports and
documents filed before the date of this Agreement), each of such reports and
documents, including the financial statements, exhibits, and schedules thereto,
complied in all material respects with all of the statutes, rules and
regulations enforced or promulgated by the authority with which they were filed
and did not contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements made therein, in light
of the circumstances under which they were made, not misleading. Other than
normal examinations conducted by the Internal Revenue Service, state and local
taxing authorities, the OTS or the FDIC in the regular course of the business of
COFI or the COFI Subsidiaries, no federal, state or local governmental agency,
commission or other entity has initiated any proceeding or, to the best
knowledge of COFI and Charter One Bank, investigation into the business or
operations of COFI or the COFI Subsidiaries within the past two years except

                                       12


<PAGE>



as set forth in Section 2.9 of the COFI Disclosure Schedule. There is no
unresolved violation, criticism or exception by the SEC, OTS, FDIC or other
agency, commission or entity with respect to any report or statement referred to
herein that is material to COFI or any COFI Subsidiary.

         2.10     COMPLIANCE WITH LAWS.

                  (a) Except as disclosed in Section 2.10 of the COFI Disclosure
         Schedule, the businesses of COFI and the COFI Subsidiaries are not
         being conducted in violation of any law, ordinance or regulation of any
         governmental entity, including, without limitation, any laws affecting
         financial institutions (including those pertaining to the Bank Secrecy
         Act, the investment of funds, the lending of money, the collection of
         interest and the extension of credit), federal and state securities
         laws, laws and regulations relating to financial statements and
         reports, truth-in-lending, truth-in-savings, usury, fair credit
         reporting, consumer protection, occupational safety, fair employment
         practices, fair labor standards and laws and regulations relating to
         employees and employee benefits, and any statutes or ordinances
         relating to the properties occupied or used by COFI or any COFI
         Subsidiary, except for possible violations which either singly or in
         the aggregate do not and, insofar as reasonably can be foreseen in the
         future, will not have a Material Adverse Effect on COFI.

                  (b) Except as disclosed in Section 2.10 of the COFI Disclosure
         Schedule, no investigation or review by any governmental entity with
         respect to COFI or any COFI Subsidiary is pending or, to the best
         knowledge of COFI and Charter One Bank, threatened, nor has any
         governmental entity indicated to COFI or any COFI Subsidiary an
         intention to conduct the same, other than normal or routine regulatory
         examinations and those the outcome of which will not have a Material
         Adverse Effect on COFI.

                  (c) COFI and each of the COFI Subsidiaries, where applicable,
         is in substantial compliance with the applicable provisions of the
         Community Reinvestment Act of 1977 and the regulations promulgated
         thereunder. As of the date of this Agreement, neither COFI nor Charter
         One Bank has been advised of the existence of any fact or circumstance
         or set of facts or circumstances which, if true, would cause COFI or
         any of the COFI Subsidiaries to fail to be in substantial compliance
         with such provisions. No COFI Subsidiary that is a financial
         institution has received a rating from an applicable regulatory
         authority which is less than "satisfactory."

         2.11 REGISTRATION STATEMENT; JOINT PROXY STATEMENT. The information to
be supplied by COFI for inclusion in the Registration Statement will not, at the
time the Registration Statement is declared effective and at the Effective Time,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading. The information to be supplied by COFI for inclusion in the Joint
Proxy Statement will not, on the date the Joint Proxy Statement (or any
amendment thereof or supplement thereto) is first mailed to stockholders of COFI
or RCSB, or at the time of their respective meetings of stockholders to

                                       13


<PAGE>



vote on this Agreement and the Company Merger, and at the Effective Time,
contain any statement that, in light of the circumstances under which it is
made, is false or misleading with respect to any material fact, omits to state
any material fact necessary in order to make the statements made therein not
false or misleading, or omits to state any material fact necessary to correct
any statement in any earlier communication with respect to the solicitation of
proxies for such meetings of stockholders that has become false or misleading.
If, at any time prior to the Effective Time, any event relating to COFI or any
of its affiliates, officers or directors is discovered by COFI that should be
set forth in an amendment to the Registration Statement or a supplement to the
Joint Proxy Statement, COFI will promptly inform RCSB and such amendment or
supplement will be promptly filed with the SEC and, as required by law,
disseminated to the stockholders of COFI and RCSB. Notwithstanding the
foregoing, COFI makes no representation or warranty with respect to any
information supplied by RCSB that is contained in any of the Registration
Statement or the Joint Proxy Statement. The Joint Proxy Statement and the
Registration Statement will (with respect to COFI) comply in all material
respects as to form and substance with the requirements of the Exchange Act, the
Securities Act, and the rules and regulations thereunder.

         2.12 LITIGATION. Except as disclosed in Section 2.12 of the COFI
Disclosure Schedule, there is no suit, action, investigation or proceeding,
legal, quasi-judicial, administrative or otherwise, pending or, to the best
knowledge of COFI and Charter One Bank threatened, against or affecting COFI or
any COFI Subsidiary, or any of their respective officers, directors, employees
or agents, in their capacities as such, which if adversely determined, would
have a Material Adverse Effect on COFI or which would materially affect the
ability of COFI, Charter Michigan or Charter One Bank to consummate the
transactions contemplated herein or which is seeking to enjoin consummation of
the transactions provided for herein or to obtain other relief in connection
with this Agreement or the transactions contemplated hereby, nor is there any
judgment, decree, injunction, rule or order of any court, governmental
department, commission agency, instrumentality or arbitrator outstanding against
COFI or any COFI Subsidiary or any of their respective officers, directors,
employees or agents, in their capacities as such, having, or which, insofar as
reasonably can be foreseen in the future, would have any such effect.

         2.13 LICENSES. COFI and the COFI Subsidiaries hold all licenses,
certificates, permits, franchises and all patents, trademarks, service marks,
trade names, copyrights or rights thereto, and required authorizations,
approvals, consents, licenses, clearances and orders or registrations with all
appropriate federal, state or other authorities that are material to the conduct
of their respective businesses as now conducted and as presently proposed to be
conducted.

         2.14 TAXES.

                  (a) Except as disclosed in Section 2.14 of the COFI Disclosure
         Schedule, COFI and the COFI Subsidiaries have each timely filed all tax
         and information returns required to be filed and have paid (or COFI has
         paid on behalf of its Subsidiaries), or have accrued on their
         respective books and set up an adequate reserve for the payment of, all

                                       14


<PAGE>



         taxes reflected on such returns or required to be paid in respect of
         the periods covered by such returns and have accrued on their
         respective books and set up an adequate reserve for the payment of all
         income and other taxes anticipated to be payable in respect of periods
         through the end of the calendar month next preceding the date hereof.
         Neither COFI nor any COFI Subsidiary is delinquent in the payment of
         any tax, assessment or governmental charge. No deficiencies for any
         taxes have been proposed, asserted or assessed against COFI or any COFI
         Subsidiary that have not been resolved or settled, and no requests for
         waivers of the time to assess any such tax are pending or have been
         agreed to. Except as set forth in Section 2.14 of the COFI Disclosure
         Schedule, neither COFI nor any COFI Subsidiary is currently subject to
         audit or examination of any of its income tax returns by the Internal
         Revenue Service or any state, municipal or other taxing authority.
         Neither COFI nor any COFI Subsidiary is a party to any action or
         proceeding by any governmental authority for the assessment or the
         collection of taxes. Deferred taxes of COFI and the COFI Subsidiaries
         have been accounted for in accordance with generally accepted
         accounting principles.

                  (b) COFI has not filed any consolidated federal income tax
         return with an "affiliated group" (within the meaning of Section 1504
         of the Code), where COFI was not the common parent of the group.
         Neither COFI nor any COFI Subsidiary is, or has been, a party to any
         tax allocation agreement or arrangement pursuant to which it has any
         contingent or outstanding liability to anyone other than COFI or a COFI
         Subsidiary.

                  (c) COFI and the COFI Subsidiaries have each withheld amounts
         from its employees, stockholders or holders of public deposit accounts
         in compliance with the tax withholding provisions of applicable
         federal, state and local laws, have filed all federal, state and local
         returns and reports for all periods for which such returns or reports
         would be due with respect to income tax withholding, social security,
         unemployment taxes, income and other taxes and all payments or deposits
         with respect to such taxes have been timely made and, except as set
         forth in Section 2.14 of the COFI Disclosure Schedule, have notified
         all employees, stockholders, and holders of public deposit accounts of
         their obligations to file all forms, statements and reports with it in
         accordance with applicable federal, state and local tax laws and have
         taken reasonable steps to insure that such employees, stockholders and
         holders of public deposit accounts have filed all such forms,
         statements and reports with it.

                  (d) For the purposes of this Agreement, the terms "tax" and
         "taxes" include, without limitation, any federal, state, local or
         foreign income, leasing, franchise, excise, gross receipts, sales, use,
         occupational, employment, real property, ad valorem, tangible and
         intangible personal property and state taxes, payments in lieu of
         taxes, levies, duties, imposts, business, operations or financial
         condition, assessments, fees, charges and withholdings of any nature
         whatsoever, together with any related penalties, fines, additions to
         tax or interest thereon.

                                       15

         2.15 INSURANCE. COFI and the COFI Subsidiaries maintain insurance with
insurers which in the best judgment of management of COFI are sound and
reputable on their respective assets and upon their respective businesses and
operations against loss or damage, risks, hazards and liabilities as in their
judgment they deem appropriate. COFI and the COFI Subsidiaries maintain in
effect all insurance required to be carried by law or by any agreement by which
they are bound. All material claims under all policies of insurance maintained
by COFI and the COFI Subsidiaries have been filed in due and timely fashion.

         2.16     LOANS; INVESTMENTS.

                  (a) Except as otherwise disclosed in Section 2.16 of the COFI
         Disclosure Schedule, each material loan reflected as an asset on the
         COFI Financial Statements dated as of December 31, 1996 is evidenced by
         appropriate and sufficient documentation and constitutes, to the best
         knowledge of COFI and Charter One Bank, the legal, valid and binding
         obligation of the obligor named therein, enforceable in accordance with
         its terms, except to the extent that the enforceability thereof may be
         limited by bankruptcy, insolvency, reorganization, moratorium or
         similar laws or equitable principles or doctrines. Except as set forth
         in Section 2.16 of the COFI Disclosure Schedule, all such loans are,
         and at the Effective Time will be, free and clear of any security
         interest, lien, encumbrance or other charge.

                  (b) All guarantees of indebtedness owed to COFI or any COFI
         Subsidiary, including but not limited to those of the Federal Housing
         Administration, the Small Business Administration, and other state and
         federal agencies, are, to the best knowledge of COFI and Charter One
         Bank, valid and enforceable, except to the extent enforceability
         thereof may be limited by applicable bankruptcy, insolvency,
         reorganization, moratorium or similar laws or equitable principles or
         doctrines and except as would not have a Material Adverse Effect on
         COFI.

                  (c) All interest rate swaps, caps, floors and option
         agreements and other interest rate risk management arrangements to
         which COFI or any COFI Subsidiary is a party or by which any of their
         properties or assets may be bound were entered into in the ordinary
         course of business and, to the best knowledge of COFI and Charter One
         Bank, in accordance with then-customary practice and applicable rules,
         regulations and policies of thrift regulatory authorities and with
         counterparties believed to be financially responsible at the time and
         are legal, valid and binding obligations and are in full force and
         effect. COFI and the COFI Subsidiaries have duly performed in all
         material respects all of their respective obligations thereunder to the
         extent that such obligations to perform have accrued, and to the best
         knowledge of COFI and Charter One Bank, there are no material breaches,
         violations or defaults or allegations or assertions of such by any
         party thereunder. None of the transactions contemplated by this
         Agreement would permit (i) a counterparty under any interest rate swap,
         cap, floor and option agreement or any other interest rate risk
         management agreement or (ii) any party to any mortgage backed security

                                       16


<PAGE>



         financing arrangement, to accelerate, discontinue, terminate, or
         otherwise modify any such agreement or arrangement or would require
         COFI or any COFI Subsidiary to recognize any gain or loss with respect
         to such arrangement.

                  (d) Except as set forth in Section 2.16 of the COFI Disclosure
         Schedule and except for pledges to secure public and trust deposits,
         none of the investments reflected in the COFI Financial Statements
         dated as of December 31, 1996 under the heading "Investment
         Securities," and none of the investments made by COFI and the COFI
         Subsidiaries since December 31, 1996, is subject to any restriction,
         whether contractual or statutory, which materially impairs the ability
         of COFI or any COFI Subsidiary to freely dispose of such investment at
         any time, other than those restrictions imposed on securities held for
         investment under generally accepted accounting principles. With respect
         to all material repurchase agreements to which COFI or any COFI
         Subsidiary is a party, COFI or such Subsidiary has a valid, perfected
         first lien, or security interest in the government securities or other
         collateral securing each such repurchase agreement, and the value of
         the collateral securing each such repurchase agreement equals or
         exceeds the amount of the debt secured by such collateral under such
         agreement.

         2.17 ALLOWANCE FOR POSSIBLE LOAN LOSSES. The allowance for possible
loan losses shown on the COFI Financial Statements as of December 31, 1996, (and
as shown on any financial statements to be delivered by COFI to RCSB pursuant to
Section 5.7 hereof), to the best knowledge of COFI and Charter One Bank, as of
such date was (and will be as of such subsequent financial statement dates)
adequate in all respects to provide for possible or specific losses, net of
recoveries relating to loans previously charged off, on loans outstanding, and
contained (or will contain) an additional amount of unallocated reserves for
unanticipated future losses at a level considered adequate under the standards
applied by applicable federal regulatory authorities and based upon generally
accepted accounting principles applicable to Charter One Bank. To the best
knowledge of COFI and Charter One Bank, the aggregate principal amount of loans
contained (or that will be contained) in the loan portfolio of COFI and the COFI
Subsidiaries as of December 31, 1996 (and as of the dates of any financial
statements to be delivered by COFI to RCSB pursuant to Section 5.7 hereof), in
excess of such reserve, was (and will be) fully collectible.

         2.18     COFI BENEFIT PLANS.
  
                  (a) The term "COFI Benefit Plans" as used herein refers to
         each compensation, consulting, employment, termination or collective
         bargaining agreement, and each stock option, stock purchase, stock
         appreciation right, life, health, accident or other insurance, bonus,
         deferred or incentive compensation, severance or separation agreement
         or any agreement providing any payment or benefit resulting from a
         change in control, profit sharing, retirement, or other employee
         benefit plan, practice, policy or arrangement of any kind, oral or
         written, covering any employee, former employee, director or former
         director of COFI or any COFI Subsidiary or his or her beneficiaries,
         including, but not limited to,

                                       17


<PAGE>



         any employee benefit plans within the meaning of Section 3(3) of the
         Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
         which COFI or any COFI Subsidiary maintains, to which COFI or any COFI
         Subsidiary contributes, or under which any employee, former employee,
         director or former director of COFI or any COFI Subsidiary is covered
         or has benefit rights and pursuant to which any liability of COFI or
         any COFI Subsidiary exists or is reasonably likely to occur, provided
         that the term "Plan or "Plans" is used in this Agreement for
         convenience only and does not constitute an acknowledgment that a
         particular arrangement is an employee benefit plan within the meaning
         of Section 3(3) of ERISA. No COFI Benefit Plan is a multi-employer plan
         within the meaning of Section 3(37) of ERISA.

                  (b) Each of the COFI Benefit Plans that is intended to be a
         pension, profit sharing, stock bonus, thrift, savings or employee stock
         ownership plan that is qualified under Section 401(a) of the Code
         ("COFI Qualified Plans") has been determined by the Internal Revenue
         Service to qualify under Section 401(a) of the Code, or an application
         for determination of such qualification has been timely made to the
         Internal Revenue Service prior to the end of the applicable remedial
         amendment period under Section 401(b) of the Code, and, to the best of
         COFI's knowledge, there exist no circumstances likely to adversely
         affect the qualified status of any such COFI Qualified Plan. All such
         COFI Qualified Plans established or maintained by COFI or any of the
         COFI Subsidiaries or to which COFI or any of the COFI Subsidiaries
         contribute are in compliance in all material respects with all
         applicable requirements of ERISA, and are in compliance in all material
         respects with all applicable requirements (including qualification and
         non-discrimination requirements) of the Code for obtaining the tax
         benefits the Code thereupon permits with respect to such COFI Qualified
         Plans. Neither COFI nor any COFI Subsidiary maintains, sponsors or
         contributes to a Qualified Plan that is a defined benefit pension plan
         subject to Title IV of ERISA. All accrued contributions and other
         payments required to be made by COFI or any COFI Subsidiary to any COFI
         Benefit Plan through December 31, 1996, have been made or reserves
         adequate for such purposes as of December 31, 1996 have been set aside
         therefor and reflected in the COFI Financial Statements dated as of
         December 31, 1996. Neither COFI nor any COFI Subsidiary is in material
         default in performing any of its respective contractual obligations
         under any of the COFI Benefit Plans or any related trust agreement or
         insurance contract, and there are no material outstanding liabilities
         of any such Plan other than liabilities for benefits to be paid to
         participants in such Plan and their beneficiaries in accordance with
         the terms of such Plan.

                  (c) There is no pending or, to the best knowledge of COFI and
         Charter One Bank, threatened litigation or pending claim (other than
         benefit claims made in the ordinary course) by or on behalf of or
         against any of the COFI Benefit Plans (or with respect to the
         administration of any of the such Plans) now or heretofore maintained
         by COFI or any COFI Subsidiary which allege violations of applicable
         state or federal law

                                       18


<PAGE>



         which are reasonably likely to result in a liability on the part of
         COFI or any COFI Subsidiary or any such Plan.

                  (d) COFI and the COFI Subsidiaries and all other persons
         having fiduciary or other responsibilities or duties with respect to
         any COFI Benefit Plan are and have since the inception of each such
         Plan been in substantial compliance with, and each such Plan is and has
         been operated in substantial accordance with, its provisions and in
         substantial compliance with the applicable laws, rules and regulations
         governing such Plan, including, without limitation, the rules and
         regulations promulgated by the Department of Labor, the Pension Benefit
         Guaranty Corporation ("PBGC") and the Internal Revenue Service under
         ERISA, the Code or any other applicable law. Notwithstanding the
         foregoing, no representation is made with respect to compliance by a
         third party insurance company. No "reportable event" (as defined in
         Section 4043(b) of ERISA) has occurred with respect to any COFI
         Qualified Plan. Neither COFI, any COFI Subsidiary nor any COFI Benefit
         Plan has incurred or is reasonably likely to incur any liability for
         any "prohibited transactions" (as defined in Section 406 of ERISA or
         Section 4975(a) of the Code), or any material liability under Section
         601 of ERISA or Section 4980 of the Code.

                  (e) COFI and the COFI Subsidiaries have filed or caused to be
         filed, and will continue to file or cause to be filed, in a timely
         manner all filings pertaining to each COFI Benefit Plan with the
         Internal Revenue Service, the PBGC, the Department of Labor, and as
         prescribed by the Code or ERISA, or regulations issued thereunder. All
         such filings, as amended, were complete and accurate in all material
         respects as of the dates of such filings. Notwithstanding the
         foregoing, no representation is made with respect to filings by a third
         party insurance company.

         whether any remedial action is needed to respond to a release or
         threatened release of any Hazardous Substance (as defined below), or
         any other substance into the environment, nor has COFI or any COFI
         Subsidiary, or, to the best knowledge of COFI and Charter One Bank, any
         owner of a Mortgaged Premises or Participating Facility been directed
         to conduct such investigation, formally or informally, by any
         governmental agency, nor have any of them agreed with any governmental

         property affected or encumbered by any document or instrument granting
         to any party hereto or any of its Subsidiaries a lien thereon or
         security interest therein; provided, however, that the term "Mortgaged
         Premises" shall not include one- to four-unit, single-family
         residences, and in the case of COFI and the COFI Subsidiaries, any real

         or any of its Subsidiaries participates in the management of such
         property and, where the context requires, includes the owner or

of COFI and Charter One Bank, no other party to any material contract or
commitment is in default in any material obligation to be performed by such
party.

("Liabilities") have, in the case of COFI and the COFI Subsidiaries, been so
reflected, disclosed or reserved against in the COFI Financial Statements dated

Subsidiaries have no other Liabilities except (a) Liabilities incurred since
December 31, 1996 in the ordinary course of business, (b) Liabilities under the
Haverfield Definitive Agreement or (c) as disclosed in Section 2.23 of the COFI
Disclosure Schedule.

         2.24     ASSETS.

                  (a) COFI and the COFI Subsidiaries have good, and marketable
         title to their real properties, including any leaseholds and ground
         leases, and their other assets and properties, all as reflected as
         owned or held by COFI in the COFI Financial Statements dated as of
         December 31, 1996, and those acquired since such date, except for (i)
         assets and properties disposed of since such date in the ordinary
         course of business and (ii) liens, none of which, in the aggregate,
         except as set forth in the COFI Financial Statements dated as of
         December 31, 1996 or in Section 2.24 of the COFI Disclosure Schedule,
         are material to the assets of COFI on a consolidated basis. All
         buildings, structures, fixtures and appurtenances comprising part of
         the real properties of COFI and the COFI Subsidiaries (whether owned or
         leased) are in good operating condition and have been well maintained,
         reasonable wear and tear excepted. Title to all real property owned by
         COFI and the COFI Subsidiaries is held in fee simple, except as
         otherwise noted in the COFI Financial Statements as of December 31,
         1996 or as set forth in Section 2.24 of the COFI Disclosure Schedule.
         COFI and the COFI Subsidiaries have title or other rights to its assets
         sufficient in all material respects for the conduct of their respective
         businesses as presently conducted, and except as set forth in the COFI
         Financial Statements dated as of December 31, 1996, or in Section 2.24
         of the COFI Disclosure Schedule, such assets are free, clear and
         discharged of and from any and all liens, charges, encumbrances,
         security interests and/or equities which are material to COFI or any
         COFI Subsidiary.

                  (b) All leases pursuant to which COFI or any COFI Subsidiary,
         as lessee, leases real or personal property which are material to the
         business of COFI on a consolidated basis are, to the best knowledge of
         COFI and Charter One Bank, valid, effective, and enforceable against
         the lessor in accordance with their respective terms. There is not
         under any of such leases any existing default, or any event which, with
         notice or lapse of time or both, would constitute a default, with
         respect to COFI or any COFI Subsidiary, or to the best knowledge of
         COFI and Charter One Bank, and the other party.

         2.25 INDEMNIFICATION. To the best knowledge of COFI and Charter One
Bank, except as set forth in Section 2.25 of the COFI Disclosure Schedule, no
action or failure to take action by any director, officer, employee or agent of
COFI or any COFI Subsidiary has occurred which would give rise to a claim by any
such person for indemnification from COFI or any COFI Subsidiary under the
corporate indemnification provisions of such entity in effect on the date of
this Agreement.

                                       22

         2.26 INSIDER INTERESTS. All outstanding loans and other contractual
arrangements (including deposit relationships) between COFI or any COFI
Subsidiary and any of its officers, directors or employees conform to applicable
rules and regulations and requirements of all applicable regulatory agencies
which were in effect when such loans and other contractual arrangements were
entered into. Except as set forth in Section 2.26 of the COFI Disclosure
Schedule, no officer, director or employee of COFI or any COFI Subsidiary has
any material interest in any property, real or personal, tangible or intangible,
used in or pertaining to the business of COFI or any COFI Subsidiary.

of COFI and Charter One Bank, there is no reason relating specifically to COFI
or any COFI Subsidiary why (a) the approvals that are required to be obtained
from regulatory authorities having approval authority in connection with the
transactions contemplated hereby should not be granted, (b) such regulatory
approvals should be subject to a condition which would differ from conditions
customarily imposed by such regulatory authorities in orders approving
acquisitions of the type contemplated hereby or (c) any of the conditions
precedent as specified in Article VI hereof to the obligations of any of the
parties hereto to consummate the transactions contemplated hereby are unlikely
to be fulfilled within the applicable time period or periods required for
satisfaction of such condition or conditions.

thereof may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium or similar laws or equitable principles or doctrines.

         3.3 CONFLICTS. Subject to the second sentence of this Section 3.3, the
execution and delivery of this Agreement does not, and the consummation of the

provision of the Certificate of Incorporation or Bylaws of RCSB or similar

material mortgage, indenture, lease, agreement or other instrument, permit,

         is or may be bound to issue additional shares of its capital stock or
         options, warrants, or rights to purchase or acquire any additional
         shares of its capital stock. Section 3.5 of the RCSB

<PAGE>



         Disclosure Schedule sets forth the name of the holder of each RCSB
         Stock Option and the date of grant of, number of shares represented by,

         3.6 RCSB FINANCIAL STATEMENTS; MATERIAL CHANGES. RCSB has heretofore
delivered to COFI its audited consolidated financial statements for fiscal years
ended November 30, 1996 and November 30, 1995 (together the "RCSB Financial

material respects; (y) have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods involved
(except as may be indicated in the notes thereto); and (z) fairly present the
consolidated financial position of RCSB as of the dates thereof and the
consolidated results of its operations, shareholders' equity, cash flows and
changes in financial position for the periods then ended. Since November 30,
1996 to the date hereof, RCSB and the RCSB Subsidiaries have not undergone or
suffered any changes in their respective condition (financial or otherwise),
properties, business or operations which have been, in any case or in the
aggregate, materially adverse to RCSB on a consolidated basis. No facts or
circumstances have been discovered from which it reasonably appears that there
is a significant risk or reasonable probability that RCSB will suffer or
experience a Material Adverse Effect.

         3.7      RCSB SUBSIDIARIES.

                  (a) All of the RCSB Subsidiaries are listed in Section 3.7 of
         the RCSB Disclosure Schedule. RCSB owns directly or indirectly all of
         the issued and outstanding shares of capital stock of the RCSB
         Subsidiaries. Section 3.7 of the RCSB Disclosure Schedule sets forth
         the number of shares of authorized and outstanding capital stock of the
         RCSB Subsidiaries. Except for equity securities of the Federal Home
         Loan Bank of New York or as set forth in Section 3.7 of the RCSB
         Disclosure Schedule, neither RCSB nor the RCSB Subsidiaries own
         directly or indirectly any equity securities, or other proprietary
         interest in any other corporation, limited liability company, joint
         venture, partnership, entity, association or other business. No capital
         stock of any of the RCSB Subsidiaries is or may become required to be
         issued (other than to RCSB) by reason of any options, warrants, scrip,
         rights to subscribe to, calls, or commitments of any character
         whatsoever relating to, or securities or rights convertible into or
         exchangeable for, shares of the capital stock of any RCSB Subsidiary.
         There are no contracts, commitments, understandings or arrangements
         relating to the rights of RCSB to vote or to dispose of shares of the
         capital stock of any RCSB Subsidiary. All of the shares of capital
         stock of each RCSB Subsidiary are fully paid and non-assessable and are
         owned by RCSB or another RCSB Subsidiary free and clear of any claim,
         lien or encumbrance, except as disclosed in Section 3.7 of the RCSB
         Disclosure Schedule.

                  (b) Each RCSB Subsidiary is either a savings bank or a
         corporation and is duly organized, validly existing and in good
         standing under the laws of the jurisdiction in which it is incorporated
         or organized, and is duly licensed or qualified to do business and is
         in good standing in each jurisdiction where the character of the assets

         leased by it or the nature of the business transacted by it requires it
         to be so licensed or qualified, except where the failure to be so
         licensed or qualified would not have a Material Adverse Effect on RCSB.
         Each RCSB Subsidiary has the corporate power and authority necessary
         for it to own, operate or lease its assets and properties and to carry
         on its business as it has been and is now being conducted.

                  (c) For purposes of this Agreement, an "RCSB Subsidiary" or a
         "Subsidiary" of RCSB shall mean each corporation, savings bank, and
         other entity in which RCSB owns or controls directly or indirectly 10%
         or more of the outstanding equity securities; provided, however, there
         shall not be included (i) Gateway American Bank, (ii) any entity that
         is inactive on the date of this Agreement, (iii) any entity acquired in
         good faith through foreclosure, or (iv) any entity to the extent that
         the equity securities of such entity are owned or controlled in a bona
         fide fiduciary capacity.

                  (d) Target Bank is a member in good standing of the Federal
         Home Loan Bank System. All eligible deposit accounts issued by Target
         Bank are insured by the FDIC through the Bank Insurance Fund ("BIF") or
         the SAIF to the full extent permitted under applicable law. Target Bank
         is, and at all times since June 1, 1990 has been, a "domestic building
         and loan association" as defined in Section 7701(a)(19) of the Code.
         The liquidation account established by Target Bank in connection with
         its conversion from mutual to stock form has been maintained since its
         establishment in accordance with applicable laws and the records with
         respect to said account are complete and accurate in all material
         respects.

         3.8 RCSB FILINGS. RCSB has previously made available, or will make

amendment required to be made with respect thereto, that it has, or will be,

thrift, securities and other regulatory authorities. As of their respective
dates (and without giving effect to any amendments or modifications filed after
the date of this Agreement with respect to reports and documents filed before
the date of this Agreement), each of such reports and documents, including the
financial statements, exhibits, and schedules thereto, complied in all material
respects with all of the statutes, rules and regulations enforced or promulgated
by the authority with which they were filed and did not contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading. Other than normal examinations conducted
by the Internal Revenue Service, state and local taxing authorities, OTS,
Department or FDIC in the regular course of the business of

                                       27


<PAGE>



RCSB or the RCSB Subsidiaries, no federal, state or local governmental agency,
commission or other entity has initiated any proceeding or, to the best
knowledge of RCSB and Target Bank, investigation into the business or operations
of RCSB or the RCSB Subsidiaries within the past two years except as set forth
in Section 3.9 of the RCSB Disclosure Schedule. There is no unresolved
violation, criticism or exception by the SEC, OTS, Department, FDIC or other
agency, commission or entity with respect to any report or statement referred to
herein that is material to RCSB or any RCSB Subsidiary.

         3.10     COMPLIANCE WITH LAWS.

                  (a) Except as disclosed in Section 3.10 of the RCSB Disclosure
         Schedule, the businesses of RCSB and the RCSB Subsidiaries are being
         conducted, in all material respects, in compliance with all laws,
         ordinances or regulations of governmental authorities, including
         without limitation, laws affecting financial institutions (including
         those pertaining to the Bank Secrecy Act, the investment of funds, the
         lending of money, the collection of interest and the extension of
         credit), federal and state securities laws, laws and regulations
         relating to financial statements and reports, truth-in-lending,
         truth-in-savings, usury, fair credit reporting, consumer protection,
         occupational safety, fair employment practices, fair labor standards
         and all other laws and regulations relating to employees and employee
         benefits, and any statutes or ordinances relating to the properties
         occupied or used by RCSB or any RCSB Subsidiary.

                  (b) Except as disclosed in Section 3.10 of the RCSB Disclosure
         Schedule, no investigation or review by any governmental entity with
         respect to RCSB or any RCSB Subsidiary is pending or, to the best
         knowledge of RCSB and Target Bank, threatened, nor has any governmental
         entity indicated to RCSB or any RCSB Subsidiary an intention to conduct
         the same, other than normal or routine regulatory examinations.

                  (c) RCSB and each of the RCSB Subsidiaries, where applicable,
         is in substantial compliance with the applicable provisions of the
         Community Reinvestment Act of 1977 and the regulations promulgated
         thereunder. As of the date of this Agreement, neither RCSB nor Target
         Bank has been advised of the existence of any fact or circumstance or
         set of facts or circumstances which, if true, would cause RCSB or any
         of the RCSB Subsidiaries to fail to be in substantial compliance with
         such provisions. Target Bank has not received a rating from an
         applicable regulatory authority which is less than "satisfactory."

         3.11 REGISTRATION STATEMENT: JOINT PROXY STATEMENT. The information to
be supplied by RCSB for inclusion in the Registration Statement will not, at the
time the Registration Statement is declared effective and at the Effective Time,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading. The information to be supplied by RCSB for inclusion in the Joint

stockholders to vote on this Agreement and the Company Merger, and at the
Effective Time, contain any statement that, in light of the circumstances under
which it is made, is false or misleading with respect to any material fact,
omits to state any material fact necessary in order to make the statements made
therein not false or misleading, or omits to state any material fact necessary
to correct any statement in any earlier communication with respect to the
solicitation of proxies for such meetings of stockholders that has become false
or misleading. If at any time prior to the Effective Time, any event relating to
RCSB or any of its affiliates, officers or directors is discovered by RCSB that
should be set forth in an amendment to the Registration Statement or a
supplement to the Joint Proxy Statement, RCSB will promptly inform COFI, and
such amendment or supplement will be promptly filed with the SEC and, as
required by law, disseminated to the stockholders of RCSB. Notwithstanding the
foregoing, RCSB makes no representation or warranty with respect to any
information supplied by COFI that is contained in the Registration Statement or
the Joint Proxy Statement. The Joint Proxy Statement will (with respect to RCSB)
comply in all material respects as to form and substance with the requirements
of the Exchange Act and the rules and regulations thereunder.

         3.12 LITIGATION. Except as disclosed in Section 3.12 of the RCSB
Disclosure Schedule, there is no suit, action, investigation or proceeding,
legal, quasi-judicial, administrative or otherwise, pending or, to the best
knowledge of RCSB and Target Bank threatened, against or affecting RCSB or any
RCSB Subsidiary, or any of their respective officers, directors, employees or
agents, in their capacities as such, which is seeking equitable relief or
damages against RCSB, any RCSB Subsidiary, or any of their respective officers,
directors, employees or agents, in their capacities as such, in excess of
$50,000, or which would materially affect the ability of RCSB or Target Bank to

consummation of the transactions provided for herein or to obtain other relief
in connection with this Agreement or the transactions contemplated hereby, nor
is there any judgment, decree, injunction, rule or order of any court,
governmental department, commission, agency, instrumentality or arbitrator
outstanding against RCSB or any RCSB Subsidiary or any of their respective
officers, directors, employees or agents, in their capacities as such, having,
or which, insofar as reasonably can be foreseen in the future, would have any
such effect.

certificates, permits, franchises and all patents, trademarks, service marks,
trade names, copyrights or right thereto, and required authorizations,

                  (a) Except as disclosed in Section 3.14 of the RCSB Disclosure
         Schedule, RCSB and the RCSB Subsidiaries have each timely filed all tax
         and information returns required to be filed and have paid (or RCSB or
         Target Bank has paid on behalf of its Subsidiaries), or have accrued on

         anticipated to be payable in respect of periods through the end of the
         calendar month next preceding the date hereof. Neither RCSB nor any
         RCSB Subsidiary is delinquent in the payment of any tax, assessment or
         governmental charge. No deficiencies for any taxes have been proposed,
         asserted or assessed against RCSB or any RCSB Subsidiary that have not
         been resolved or settled and no requests for waivers of the time to

         RCSB nor any RCSB Subsidiary is, or has been, a party to any tax
         allocation agreement or arrangement pursuant to which it has any
         contingent or outstanding liability to anyone other than RCSB or any
         RCSB Subsidiary. Neither RCSB nor any RCSB Subsidiary is required to
         include in income any adjustment pursuant to Section 481(a) of the Code
         and no such adjustment has been proposed by the Internal Revenue
         Service. Neither RCSB nor any RCSB Subsidiary has filed a consent
         pursuant to Section 341(f) of the Code or agreed to have Section
         341(f)(2) of the Code apply.

                  (c) RCSB and the RCSB Subsidiaries have each withheld amounts
         from its employees, stockholders, or holders of public deposit accounts
         in compliance with the tax withholding provisions of applicable
         federal, state and local laws, have filed all federal, state and local
         returns and reports for all periods for which such returns or reports
         would be due with respect to income tax withholding, social security,

         taken reasonable steps to insure that such employees, stockholders and
         holders of public deposit accounts have filed all such forms statements
         and reports with it.

insurers which in the best judgment of management of RCSB are sound and
reputable on their respective assets and upon their respective businesses and
operations against loss or damage, risks, hazards and liabilities as in their
judgment they deem appropriate. RCSB and the RCSB Subsidiaries maintain in
effect all insurance required to be carried by law or by any agreement by which

RCSB Subsidiaries has taken or will timely take all requisite action (including
without limitation the making of claims and the giving of notices) pursuant to
its directors' and officers' liability insurance policy or policies in order to
preserve all rights thereunder with respect to all matters (other than matters
arising in connection with this Agreement and the transactions contemplated
hereby) occurring prior to the Effective Time. Neither RCSB nor any of the RCSB
Subsidiaries has, during the past three years, had an insurance policy canceled
or been denied insurance coverage for which any of such companies has applied.

         material loan originated or acquired by RCSB or an RCSB Subsidiary
         since such date, is evidenced by appropriate and sufficient
         documentation and constitutes, to the best knowledge of RCSB and Target
         Bank, the legal, valid and binding obligation of the obligor named
         therein, enforceable in accordance with its terms, except to the extent
         that the enforceability thereof may be limited by bankruptcy,
         insolvency, reorganization, moratorium or similar laws or equitable
         principles or doctrines. Except as set forth in Section 3.16 of the
         RCSB Disclosure Schedule and loans sold in the ordinary course of
         business, all such loans are, and at the Effective Time will be, free
         and clear of any security interest, lien, encumbrance or other charge.
         Except as set forth in Section 3.16 of the RCSB Disclosure Schedule,
         there is no loan or other asset of RCSB or of any RCSB Subsidiary that
         has been classified by examiners or others as "Other Loans of Concern,"
         "Substandard," "Doubtful" or "Loss" as of April 30, 1997. Set forth in

         Target Bank, valid and enforceable, except to the extent enforceability
         thereof may be limited by applicable bankruptcy, insolvency,
         reorganization, moratorium or similar laws or equitable principles or
         doctrines.

                  (c) All interest rate swaps, caps, floors and option
         agreements and other interest rate risk management arrangements to
         which RCSB or any RCSB Subsidiary is a party or by which any of their
         properties or assets may be bound were entered into in the ordinary
         course of business and, to the best knowledge of RCSB and Target Bank,
         in accordance with then-customary practice and applicable rules,
         regulations and policies of thrift regulatory authorities and with
         counterparties believed to be financially responsible at the time and

<PAGE>



         RCSB and the RCSB Subsidiaries have duly performed in all material
         respects all of their respective obligations thereunder to the extent
         that such obligations to perform have accrued, and to the best
         knowledge of RCSB and Target Bank, there are no material breaches,
         violations or defaults or allegations or assertions of such by any
         party thereunder. Except as set forth in Section 3.16 of the RCSB
         Disclosure Schedule, none of the transactions contemplated by this
         Agreement would permit: (i) a counterparty under any interest rate
         swap, cap, floor and option agreement or any other interest rate risk
         management agreement or (ii) any party to any mortgage-backed security
         financing arrangement, to accelerate, discontinue, terminate or
         otherwise modify any such agreement or arrangement or would require
         RCSB or any RCSB Subsidiary to recognize any gain or loss with respect
         to such arrangement.

                  (d) Except as set forth in Section 3.16 of the RCSB Disclosure
         Schedule and except for pledges to secure public and trust deposits,
         none of the investments reflected in the RCSB Financial Statements
         dated as of November 30, 1996 under the heading "Investment Securities,
         " and none of the investments made by RCSB and the RCSB Subsidiaries
         since November 30, 1996, is subject to any restriction, whether
         contractual or statutory, which materially impairs the ability of RCSB
         or any RCSB Subsidiary to freely dispose of such investment at any
         time, other than those restrictions imposed on securities held for
         investment under generally accepted accounting principles. With respect
         to all repurchase agreements to which RCSB or any RCSB Subsidiary is a
         party, RCSB or such Subsidiary has a valid, perfected first lien or
         security interest in the government securities or other collateral
         securing each such repurchase agreement, and the value of the
         collateral securing each such repurchase agreement equals or exceeds
         the amount of the debt secured by such collateral under such agreement.

                  (e) All United States Treasury securities, obligations of
         other United States Government agencies and corporations, obligations
         of States of United States and their political subdivisions, and other
         investment securities classified as "held to maturity" and "available
         for sale" held by RCSB and the RCSB Subsidiaries, as reflected in the
         RCSB Financial Statements dated November 30, 1996 were classified and
         accounted for in accordance with F.A.S.B. 115 and the intentions of
         management.

         3.17     ALLOWANCE FOR POSSIBLE LOAN LOSSES.

                  (a) The allowance for possible loan losses shown on the RCSB
         Financial Statements as of November 30, 1996 (and as shown on any
         financial statements to be delivered by RCSB to COFI pursuant to
         Section 5.7 hereof), to the best knowledge of RCSB and Target Bank, as
         of such date was (and will be as of such subsequent financial statement
         dates) adequate in all respects to provide for possible or specific
         losses, net of recoveries relating to loans previously charged off, on
         loans outstanding, and contained (or will contain) an additional amount
         of unallocated reserves for unanticipated future losses at a level
         considered adequate under the standards applied by applicable federal

                                       32


<PAGE>



         regulatory authorities and based upon generally accepted practices
         applicable to Target Bank and the other RCSB Subsidiaries. To the best
         knowledge of RCSB and Target Bank, the aggregate principal amount of
         loans contained (or that will be contained) in the loan portfolio of
         RCSB and the RCSB Subsidiaries as of November 30, 1996 (and as of the
         dates of any financial statements to be delivered by RCSB to COFI
         pursuant to Section 5.7 hereof), in excess of such reserve, was (and
         will be) fully collectible.

                  (b) The sum of the aggregate amount of all Nonperforming
         Assets (as defined below) and all troubled debt restructurings (as
         defined under generally accepted accounting principles) on the books of
         RCSB and the RCSB Subsidiaries does not exceed 1.8% of total loans as
         of April 30, 1997. "Nonperforming Assets" shall mean (i) all loans and
         leases (A) that are contractually past due 90 days or more in the
         payment of principal and/or interest, (B) that are on nonaccrual
         status, (C) where a reasonable doubt exists, in the reasonable judgment
         of Target Bank or any other RCSB Subsidiary, as to the timely future
         collectibility of principal and/or interest, whether or not interest is
         still accruing or the loan is less than 90 days past due, (D) where the
         interest rate terms have been reduced and/or the maturity dates have
         been extended subsequent to the agreement under which the loan was
         originally created due to concerns regarding the borrower's ability to
         pay in accordance with such initial terms, (other than restructured
         loans that have ceased to be nonperforming in accordance with
         applicable regulatory guidelines and generally accepted accounting
         principles), (E) where a specific reserve allocation exists in
         connection therewith, or (F) that have been classified "Doubtful",
         "Loss" or the equivalent thereof by any regulatory authority, and (ii)
         all assets classified as REO and all other assets acquired through
         foreclosure or repossession.

         3.18     RCSB BENEFIT PLANS.

                  (a) Section 3.18 of the RCSB Disclosure Schedule contains a
         list (or, a description with respect to any oral employee benefit plan,
         practice, policy or arrangement), including all amendments thereto, of
         each compensation, consulting, employment, termination or collective
         bargaining agreement, and each stock option, stock purchase, stock
         appreciation right ("SAR"), restricted stock, stock equivalent ("Stock
         Equivalent"), life, health, accident or other insurance, bonus,
         deferred or incentive compensation, severance or separation agreement
         or any agreement providing any payment or benefit resulting from a
         change in control, profit sharing, retirement, or other employee
         benefit plan, practice, policy or arrangement of any kind, oral or
         written, covering any employee, former employee, director or former
         director of RCSB or any RCSB Subsidiary or his or her beneficiaries,
         including, but not limited to, any employee benefit plans within the
         meaning of Section 3(3) of ERISA, which RCSB or any RCSB Subsidiary
         maintains, to which RCSB or any RCSB Subsidiary contributes, or under
         which any employee, former employee, director or former director of
         RCSB or any RCSB Subsidiary is covered or has benefit rights and
         pursuant to which any liability of RCSB or any RCSB Subsidiary exists
         or is reasonably likely to occur (the "RCSB Benefit Plans").

         Except as set forth in Section 3.18 of the RCSB Disclosure Schedule,
         RCSB and the RCSB Subsidiaries neither maintain nor have entered into
         any RCSB Benefit Plan or other document, plan or agreement which
         contains any change in control provisions which would cause an increase
         or acceleration of benefits or benefit entitlements to employees or
         former employees of RCSB or any RCSB Subsidiary or their respective
         beneficiaries, or other provisions, which would cause an increase in
         the liability of RCSB or any RCSB Subsidiary or to COFI or any COFI
         Subsidiary as a result of the transactions contemplated by this
         Agreement or any related action thereafter (a "Change in Control
         Benefit"). The term "RCSB Benefit Plans" as used herein refers to all
         plans contemplated under the preceding sentences of this Section 3.18,
         provided that the term "Plan" or "Plans" is used in this Agreement for
         convenience only and does not constitute an acknowledgment that a
         particular arrangement is an employee benefit plan within the meaning
         of Section 3(3) of ERISA. Except as disclosed in Section 3.18 of the
         RCSB Disclosure Schedule, no RCSB Benefit Plan is a multi-employer plan
         within the meaning of Section 3(37) of ERISA.

                  (b) Each of the RCSB Benefit Plans that is intended to be a
         pension, profit sharing, stock bonus, thrift, savings plan that is
         qualified under Section 401(a) of the Code ("RCSB Qualified Plans") has
         been determined by the Internal Revenue Service to qualify under
         Section 401(a) of the Code, or an application for determination of such
         qualification has been timely made to the Internal Revenue Service
         prior to the end of the applicable remedial amendment period under
         Section 401(b) of the Code (a copy of each such determination letter or
         pending application is included in Section 3.18 of the RCSB Disclosure
         Schedule) and, to the best of RCSB's knowledge, there exist no
         circumstances likely to adversely affect the qualified status of any
         such RCSB Qualified Plan. All such RCSB Qualified Plans established or
         maintained by RCSB or any of the RCSB Subsidiaries or to which RCSB or
         any of the RCSB Subsidiaries contribute are in compliance in all
         material respects with all applicable requirements of ERISA, and are in
         compliance in all material respects with all applicable requirements
         (including qualification and non-discrimination requirements ) of the
         Code for obtaining the tax benefits the Code thereupon permits with
         respect to such RCSB Qualified Plans. Neither RCSB nor any RCSB
         Subsidiary is a plan sponsor of, or contributes to, a defined benefit
         pension plan. All accrued contributions and other payments required to
         be made by RCSB or any RCSB Subsidiary to any RCSB Benefit Plan through
         November 30, 1996, have been made or reserves adequate for such
         purposes as of November 30, 1996, have been set aside therefor and are
         reflected in the RCSB Financial Statements dated as of November 30,
         1996. Neither RCSB nor any RCSB Subsidiary is in material default in
         performing any of its contractual obligations under any of the RCSB
         Benefit Plans or any related trust agreement or insurance contract, and
         there are no material outstanding liabilities of any such Plan other
         than liabilities for benefits to be paid to participants in such Plan
         and their beneficiaries in accordance with the terms of such Plan.

                  (c) There is no pending or, to the best knowledge of RCSB and
         Target Bank, threatened litigation or pending claim (other than routine
         benefit claims made in the ordinary course) by or on behalf of or
         against any of the RCSB Benefit Plans (or with

                                       34


<PAGE>



         respect to the administration of any such Plans) now or heretofore
         maintained by RCSB or any RCSB Subsidiary which allege violations of
         applicable state or federal law which are reasonably likely to result
         in a liability on the part of RCSB or any RCSB Subsidiary or any such
         Plan.

                  (d) RCSB and the RCSB Subsidiaries and all other person having
         fiduciary or other responsibilities or duties with respect to any RCSB
         Benefit Plan are and have since the inception of each such Plan been in
         substantial compliance with, and each such Plan is and has been
         operated in substantial accordance with, its provisions and in
         substantial compliance with the applicable laws, rules and regulations
         governing such Plan, including, without limitation, the rules and
         regulations promulgated by the Department of Labor, the PBGC and the
         Internal Revenue Service under ERISA, the Code or any other applicable
         law. Notwithstanding the foregoing, no representation is made with
         respect to compliance by a third party insurance company. No
         "reportable event" (as defined in Section 4043(b) of ERISA) has
         occurred with respect to any RCSB Benefit Plan. No RCSB Benefit Plan
         has engaged in or been a party to a "prohibited transaction" (as
         defined in Section 406 of ERISA or Section 4975(c) of the Code). All
         RCSB Benefit Plans that are group health plans have been operated in
         substantial compliance with the group health plan continuation
         requirements of Section 4980B of the Code and Section 601 of ERISA.

                  (e) Except as set forth in Section 3.18 of the RCSB Disclosure
         Schedule, neither RCSB nor any RCSB Subsidiary has made any payments,
         or is or has been a party to any agreement or any RCSB Benefit Plan,
         that under any circumstances could obligate it or its successor to make
         payments that are not or will not be deductible because of Sections
         162(m) or 280G of the Code.

                  (f) Section 3.18 of the RCSB Disclosure Schedule describes any
         obligation that RCSB or any RCSB Subsidiary has to provide health or
         welfare benefits to retirees or other former employees, directors or
         their dependents (other than rights under Section 4980B of the Code or
         Section 601 of ERISA), including information as to the number of
         retirees, other former employees or directors and dependents entitled
         to such coverage and their ages.

                  (g) Section 3.18 of the RCSB Disclosure Schedule lists: (i)
         each officer, employee and director of RCSB and any RCSB Subsidiary who
         is eligible to receive a Change in Control Benefit, showing the amount
         of each such Change in Control Benefit, the individual's participation
         in each bonus and other RCSB Benefit Plan, and such individual's
         compensation from RCSB and each RCSB Subsidiary for each of the
         calendar years 1992 through 1996 as reported by RCSB and a RCSB
         Subsidiary on Form W-2 or Form 1099; and (ii) a copy of each form of
         agreement relating to RCSB Stock Options, SARs and Stock Equivalents.

                  (h) RCSB and the RCSB Subsidiaries have filed or caused to be
         filed, and will continue to file or cause to be filed, in a timely
         manner all filings pertaining to each RCSB

                                       35

         Benefit Plan with the Internal Revenue Service and the Department of
         Labor, as prescribed by the Code or ERISA, or regulations issued
         thereunder. All such filings, as amended, were complete and accurate in
         all material respects as of the dates of such filings. Notwithstanding
         the foregoing, no representation is made with respect to filings by a
         third party insurance company.

                  3.19     COMPLIANCE WITH ENVIRONMENTAL LAWS.

                  (a) Except as set forth in Section 3.19 of the RCSB Disclosure
         Schedule: (i) to the best knowledge of RCSB and Target Bank, the
         operations of RCSB and each of the RCSB Subsidiaries comply in all
         material respects with all applicable past and present Environmental
         Laws; (ii) to the best knowledge of RCSB and Target Bank, none of the
         operations of RCSB or any RCSB Subsidiary, no assets presently or
         formerly owned or leased by RCSB or any RCSB Subsidiary and no
         Mortgaged Premises or Participating Facility are subject to any
         judicial or administrative proceedings alleging the violation of any
         past or present Environmental Law, nor are they the subject of any
         claims alleging damages to health or property, pursuant to which RCSB,
         any RCSB Subsidiary or any owner of a Mortgaged Premises or a
         Participating Facility would be liable in law or equity; (iii) none of
         the operations of RCSB or any RCSB Subsidiary, no assets presently
         owned or, to the best knowledge of RCSB and Target Bank, formerly owned
         by RCSB or any RCSB Subsidiary, and to the best knowledge of RCSB and
         Target Bank, no Mortgaged Premises or a Participating Facility are the
         subject of any federal, state or local investigation evaluating whether
         any remedial action is needed to respond to a release or threatened
         release of any Hazardous Substance, or any other substance into the
         environment, nor has RCSB or any RCSB Subsidiary, or, to the best
         knowledge of RCSB and Target Bank, any owner or a Mortgaged Premises or
         a Participating Facility been directed to conduct such investigation,
         formally or informally, by any governmental agency, nor have any of
         them agreed with any governmental agency or private person to conduct
         any such investigation; and (iv) neither RCSB nor any RCSB Subsidiary,
         nor, to the best knowledge of RCSB and Target Bank, any owner of a
         Mortgaged Premises or a Participating Facility has filed any notice
         under any Environmental Law indicating past or present treatment,
         storage or disposal of a Hazardous Substance or reporting a spill or
         release of a Hazardous Substance, or any other substance into the
         environment.

                  (b) With respect to the real property currently owned or, to
         the best knowledge of RCSB and Target Bank, formerly owned or currently
         leased by RCSB or any RCSB Subsidiary ("RCSB Premises"): (x) no part of
         the RCSB Premises has been used for the generation, manufacture,
         handling, storage, or disposal of Hazardous Substances; (y) except as
         disclosed in Section 3.19 of the RCSB Disclosure Schedule, the RCSB
         Premises do not contain, and have never contained, an underground
         storage tank; and (z) the RCSB Premises do not contain and are not
         contaminated by any quantity of a Hazardous Substance from any source.
         With respect to any underground storage tank listed in Section 3.19 of
         the RCSB Disclosure Statement as an exception to the foregoing,

                                       36


<PAGE>



         such underground storage tank has been removed in compliance with the
         Environmental Laws, and has not been the source of any release of a
         Hazardous Substance into the environment, unless otherwise set forth in
         Section 3.19 of the RCSB Disclosure Schedule.

         limitation, fire and other hazard insurance on its assets, automobile

the ordinary course of business or (b) as disclosed in Section 3.24 of the RCSB
Disclosure Schedule.

         3.25     ASSETS.

                  (a) RCSB and the RCSB Subsidiaries have good and marketable
         title to their real properties, including any leaseholds and ground
         leases, and their other assets and properties, all as reflected as
         owned or held by RCSB or any RCSB Subsidiary in the RCSB Financial
         Statements dated as of November 30, 1996, and those acquired since such
         date, except for (i) assets and properties disposed of since such date
         in the ordinary course of business and (ii) liens and encumbrances none
         of which, in the aggregate, except as set forth in the RCSB Financial
         Statements dated November 30, 1996 or in Section 3.25 of the RCSB
         Disclosure Schedule, are material to the assets of RCSB on a
         consolidated basis. All buildings, structures, fixtures and
         appurtenances comprising part of the real properties of RCSB and the
         RCSB Subsidiaries (whether owned or leased) are in good operating
         condition and have been well maintained, reasonable wear and tear
         excepted. Title to all real property owned by RCSB and the RCSB
         Subsidiaries is held in fee simple, except as otherwise noted in the
         RCSB Financial Statements as of November 30, 1996 or as set forth in
         Section 3.25 of the RCSB Disclosure Schedule. RCSB and the RCSB
         Subsidiaries have title or other rights to its assets sufficient in all
         material respect for the conduct of their respective businesses as
         presently conducted, and except as set forth in the RCSB Financial
         Statements dated as of November 30, 1996 or in Section 3.25 of the RCSB
         Disclosure Schedule, such assets are free, clear and discharged of and
         from any and all liens, charges, encumbrances, security interests
         and/or equities which are material to RCSB or any RCSB Subsidiary.

                  (b) All material leases pursuant to which RCSB or any RCSB
         Subsidiary, as lessee, leases real or personal property are, to the
         best knowledge of RCSB and Target Bank, valid, effective, and
         enforceable against the lessor in accordance with their respective
         terms. There is not under any of such leases any existing default, or
         any event which with notice or lapse of time or both would constitute a
         default, with respect to either RCSB or any RCSB Subsidiary, or to the
         best knowledge of RCSB and Target Bank, the other party. Except as
         disclosed in Section 3.25 of the RCSB Disclosure Schedule, none of such
         leases contains a prohibition against assignment by RCSB or any RCSB
         Subsidiary, by operation of law or otherwise, or any other provision
         which would preclude the surviving corporation or resulting institution
         or any RCSB Subsidiary from possessing and using the leased premises
         for the same purposes and upon the same rental and other terms upon the
         consummation of the Merger as are applicable to the use by RCSB or any
         RCSB Subsidiary as of the date of this Agreement.

         3.26 INDEMNIFICATION. To the best knowledge of RCSB and Target Bank,
except as set forth in Section 3.26 of the RCSB Disclosure Schedule, no action
or failure to take action by any director, officer, employee or agent of RCSB or
any RCSB Subsidiary has occurred which

                                       42


<PAGE>



would give rise to a claim or a potential claim by any such person for
indemnification from RCSB or any RCSB Subsidiary under the corporate
indemnification provisions of RCSB or any RCSB Subsidiary.

         3.27 INSIDER INTERESTS. All outstanding loans and other contractual
arrangements (including deposit relationships) between RCSB or any RCSB
Subsidiary and any officer, director or employee of RCSB or any RCSB Subsidiary
conform to the applicable rules and regulations and requirements of all
applicable regulatory agencies which were in effect when such loans and other
contractual arrangements were entered into. Except as set forth in Section 3.27
of the RCSB Disclosure Schedule, no officer, director or employee of RCSB or any
RCSB Subsidiary has any material interest in any property, real or personal,
tangible or intangible, used in or pertaining to the business of RCSB or any
RCSB Subsidiary.

         3.28 REGISTRATION OBLIGATIONS. Except as set forth in Section 3.28 of
the RCSB Disclosure Schedule, neither RCSB nor any RCSB Subsidiary is under any
obligation, contingent or otherwise, which will survive the Effective Time by
reason of any agreement to register any of its securities under the Securities
Act or other federal or state securities laws or regulations.

         3.29 REGULATORY, TAX AND ACCOUNTING MATTERS. RCSB and Target Bank have
not taken or agreed to take any action, nor does it have knowledge of any fact
or circumstance, that would (i) materially impede or delay the consummation of
the transactions contemplated by this Agreement or the ability of the parties to
obtain any approval of any regulatory authority required for the transactions
contemplated by this Agreement or to perform their covenants and agreements
under this Agreement or (ii) prevent the Merger from qualifying as a pooling of
interests for accounting purposes or the Merger from qualifying as a
reorganization within the meaning of Section 368(a) of the Code.

         3.30 BROKERS AND FINDERS. Except as set forth in the agreement with
Lehman Brothers, dated April 30, 1997 (which agreement has not been amended
since such date), a copy of which has previously been provided to COFI, neither
RCSB nor any RCSB Subsidiary nor any of their respective officers, directors or
employees has employed any broker or finder or incurred any liability for any
financial advisory fees, brokerage fees, commissions or finder's fees, and no
other broker or finder has acted directly or indirectly for RCSB or any RCSB
Subsidiary in connection with this Agreement or the transactions contemplated
hereby. Section 3.30 of the RCSB Disclosure Schedule sets forth bona fide
estimates of the amounts of all fees and expenses to be paid by RCSB to all
third parties in connection with this Agreement and the transactions
contemplated hereby.

         3.31 ACCURACY OF INFORMATION. The statements of RCSB and Target Bank
contained in this Agreement, the Schedules hereto and any other written document
executed and delivered by or on behalf of RCSB or Target Bank pursuant to the
terms of this Agreement are true and correct in all material respects.

         3.32 FAIRNESS OPINION. RCSB has received from Lehman Brothers a
fairness opinion, dated as of the date of this Agreement, to the effect that the
Merger Consideration to be received by the holders of RCSB Common Stock pursuant
to this Agreement and the Company Merger is fair to such holders from a
financial point of view.

         3.33 GOVERNMENTAL APPROVALS AND OTHER CONDITIONS. To the knowledge of
RCSB and Target Bank, there is no reason relating specifically to RCSB or any of
its Subsidiaries why (a) the approvals that are required to be obtained from
regulatory authorities having approval authority in connection with the
transactions contemplated hereby should not be granted, (b) such regulatory
approvals should be subject to a condition which would differ from conditions
customarily imposed by such regulatory authorities in orders approving
acquisitions of the type contemplated hereby or (c) any of the conditions
precedent as specified in Article VI hereof to the obligations of any of the
parties hereto to consummate the transactions contemplated hereby are unlikely
to be fulfilled within the applicable time period or periods required for
satisfaction of such condition or conditions.

                                   ARTICLE IV

         compliance with their existing business plan, a copy of which has been
         heretofore delivered by RCSB to COFI (the "1997 RCSB Business Plan"),
         and by way of amplification and not limitation, RCSB and each of the
         RCSB Subsidiaries will not, without the prior written consent of COFI

                  (c) During the period commencing July 1, 1997, and ending the
         last day of the calendar month coinciding with or immediately preceding
         the Closing Date, RCSB and the RCSB Subsidiaries shall cause units with
         a Fair Issac Corporation Auto Score (as calculated by the RCSB
         Subsidiary based on maker or co-maker in its reports prepared in the
         ordinary course of business consistent with past practice) of 599 or
         less not to exceed 8% of the total auto unit production originated by
         RCSB and the RCSB Subsidiaries during such period on a consolidated
         basis.

                  (d) RCSB will, and will cause the RCSB Subsidiaries to, use
         their reasonable efforts to maintain their respective properties and
         assets in their present state of repair, order and condition,
         reasonable wear and tear excepted, and to maintain and keep in full
         force and effect all policies of insurance presently in effect,
         including in the case of Target Bank insurance of accounts with the
         FDIC. RCSB will, and will cause the RCSB Subsidiaries to, take all
         requisite action (including without limitation the making of claims and
         the giving of notices) pursuant to its directors' and officers'
         liability insurance policy or

                                       47


<PAGE>



         policies in order to preserve all rights thereunder with respect to all
         matters which could reasonably give rise to a claim prior to the
         Effective Time.

                  (e) RCSB shall promptly notify COFI in writing of the
         occurrence of any matter or event known to and directly involving RCSB
         or any RCSB Subsidiary that is reasonably likely to result in a
         Material Adverse Effect on RCSB or impair the ability of RCSB or Target
         Bank to consummate the transactions contemplated herein.

                  (f) RCSB shall provide to COFI such reports on litigation
         involving RCSB and each of the RCSB Subsidiaries as COFI shall
         reasonably request, provided that RCSB shall not be required to divulge
         information to the extent that, in the good faith opinion of its
         counsel, by doing so, it would risk waiver of the attorney-client
         privilege to its detriment.

                  (g) Neither RCSB (nor any of its Subsidiaries) (i) shall
         solicit, initiate, participate in discussions of, or encourage or take
         any other action to facilitate (including by way of the disclosing or
         furnishing of any information that it is not legally obligated to
         disclose or furnish) any inquiry or the making of any proposal relating
         to any Acquisition Transaction (as defined below) or a potential
         Acquisition Transaction with respect to itself or any of its
         Subsidiaries or (ii) shall (A) solicit, initiate, participate in
         discussions of, or encourage or take any other action to facilitate any
         inquiry or proposal, or (B) enter into any agreement, arrangement, or
         understanding (whether written or oral) regarding any proposal or
         transaction providing for or requiring it to abandon, terminate or fail
         to consummate this Agreement, or compensating it or any of its
         Subsidiaries under any of the instances described in this clause. RCSB
         and Target Bank shall immediately instruct and otherwise use their best
         efforts to cause their directors, officers, employees, agents, advisors
         (including, without limitation, any investment banker, attorney, or
         accountant retained by it or any of its Subsidiaries), consultants and
         other representatives to comply with such prohibitions. RCSB and Target
         Bank shall immediately cease and cause to be terminated any existing
         activities, discussions, or negotiations with any parties conducted
         heretofore with respect to such activities. Notwithstanding the
         foregoing, RCSB may provide information at the request of or enter into
         negotiations with a third party with respect to an Acquisition
         Transaction if the Board of Directors of RCSB determines, in good faith
         after consultation with counsel, that the exercise of its fiduciary
         duties to RCSB's stockholders under applicable law requires it to take
         such action, and, provided further, that RCSB may not, in any event,
         provide to such third party any information which it has not provided
         to COFI. RCSB shall promptly notify COFI orally and in writing in the
         event it receives any such inquiry or proposal and shall provide
         reasonable detail of all relevant facts relating to such inquiries.
         This Section shall not prohibit accurate disclosure by RCSB in any
         document (including the Joint Proxy Statement and the Registration
         Statement) or other disclosure under applicable law if in the opinion
         of the Board of Directors of RCSB, disclosure is appropriate under
         applicable law. "Acquisition Transaction" shall, with respect to RCSB,
         mean any of the following (other

                                       48


<PAGE>



         than the Merger): (i) a merger or consolidation, or any similar
         transaction of any company with either RCSB or any Subsidiary of RCSB,
         (ii) a purchase, lease or other acquisition of a material portion of
         all the assets of either RCSB or any Subsidiary of RCSB, (iii) a
         purchase or other acquisition of "beneficial ownership" by any "person"
         or "group" (as such terms are defined in Section 13(d)(3) of the
         Exchange Act) (including by way of merger, consolidation, share
         exchange, or otherwise) which would cause such person or group to
         become the beneficial owner of securities representing 10% or more of
         the voting power of either RCSB or any Subsidiary of RCSB, (iv) a
         tender or exchange offer to acquire securities representing 19.9% or
         more of the voting power of RCSB, (v) a public proxy or consent
         solicitation made to stockholders of RCSB seeking proxies in opposition
         to any proposal relating to any of the transactions contemplated by
         this Agreement, (vi) the filing of an application or notice with the
         OTS, the Department, or any other federal or state regulatory authority
         (which application has been accepted for processing) seeking approval
         to engage in one or more of the transactions referenced in clauses (i)
         through (iv) above, or (vii) the making of a bona fide offer to the
         Board of Directors of RCSB or Target Bank by written communication,
         that is or becomes the subject of public disclosure, to engage in one
         or more of the transactions referenced in clauses (i) through (v)
         above.

                  (h) At the request of COFI, Target Bank agrees immediately
         prior to Closing and after satisfaction or waiver of the conditions to
         Closing set forth in Article VI hereof, to establish and take such
         reserves and accruals as COFI reasonably shall request to conform
         Target Bank's loan, accrual, reserve and other accounting policies to
         the policies of Charter One Bank, provided however, such requested
         conforming adjustments shall not be taken into account in determining
         whether RCSB has experienced a Material Adverse Effect.

         4.2 MUTUAL COVENANTS. No party to this Agreement shall voluntarily take
any action that would (A) materially impede or delay the consummation of the
transactions contemplated by this Agreement or the ability of the parties hereto
to obtain any approval of any regulatory authority required for the transactions
contemplated by this Agreement or to perform its covenants and agreements under
this Agreement or (B) prevent the Merger from qualifying as a pooling of
interests for accounting purposes or as a reorganization within the meaning of
Section 368(a) of the Code. The exercise by COFI of its rights under the Stock
Option Agreement shall not be deemed a violation of this Section or a breach of
any representation made by COFI under this Agreement.

                              ADDITIONAL AGREEMENTS

         5.1      INSPECTION OF RECORDS; CONFIDENTIALITY.

                  (a) COFI and RCSB shall each afford to the other and to the
         other's accountants, counsel and other representatives (and their
         Subsidiaries) full access during normal business hours during the
         period prior to the Effective Time to all of their respective
         properties, books, contracts, commitments and records, including all
         attorneys' responses to auditors' requests for information, and
         accountants' work papers, developed by either of them or their
         respective Subsidiaries or their respective accountants or attorneys,
         and will permit each other and their respective representatives to
         discuss such information directly with each other's officers,
         directors, employees, attorneys and accountants. COFI and RCSB shall
         each use their best efforts to furnish to the other all other
         information concerning its business, properties and personnel as such
         other party may reasonably request. Any failure to comply with this
         covenant shall be disregarded if promptly corrected without material
         adverse consequences to the other party. The availability or actual
         delivery of information shall not affect the representations,
         warranties, covenants, and agreements of the party providing such
         information that are contained in this Agreement or in any certificates
         or other documents delivered pursuant hereto.

                  (b) All information disclosed by any party to any other party
         to this Agreement, whether prior or subsequent to the date of this
         Agreement including, without limitation, any information obtained
         pursuant to this Section 5.1, shall be kept confidential by such other
         party and shall not be used by such other party otherwise as herein
         contemplated. In the event that this Agreement is terminated, each
         party shall return all documents furnished hereunder, shall destroy all
         documents or portions thereof prepared by such other party that contain
         information furnished by another party pursuant hereto and, in any
         event, shall hold all information confidential unless or until such
         information is or becomes a matter of public knowledge.

         5.2 REGISTRATION STATEMENT; STOCKHOLDER APPROVAL. As soon as
practicable after the date hereof, COFI shall file the Registration Statement
with the SEC, and RCSB and COFI shall use their best efforts to cause the
Registration Statement to become effective under the Securities Act. COFI will
take any action required to be taken under the applicable blue sky or securities
laws in connection with the issuance of the shares of COFI Common Stock in the
Company Merger. Each party shall furnish all information concerning it and the
holders of its capital stock as the other party may reasonably request in
connection with such action. Each of COFI and RCSB shall call a meeting of its
stockholders as soon as practicable after the Registration Statement is declared
effective by the SEC for the purpose of voting upon this Agreement and the

                                       50


<PAGE>



Company Merger and shall schedule such meeting based on consultation with the
other party. In connection with said stockholders' meetings, (i) COFI and RCSB
shall jointly prepare the Joint Proxy Statement as part of the Registration
Statement and they shall mail the Joint Proxy Statement to their respective
stockholders and (ii) the Board of Directors of COFI and RCSB shall recommend to
their respective stockholders the approval of this Agreement and the Company
Merger; provided, however, that such recommendation may be withdrawn, modified,
or amended, or not made at all, after the receipt by RCSB of an offer to effect
an Acquisition Transaction (as defined in Section 4.1(g) hereof) with RCSB to
the extent the Board of Directors of RCSB reasonably determines that, in the
exercise of its fiduciary obligations after consultation with counsel, it has a
duty to do so.

         5.3 AGREEMENTS OF AFFILIATES. As soon as practicable after the date of
this Agreement, RCSB shall deliver to COFI a letter, reviewed by its counsel,
identifying all persons whom RCSB believes to be "affiliates" of RCSB for
purposes of Rule 145 under the Securities Act or for purposes of qualifying for
pooling of interests accounting treatment for the Merger. RCSB shall use its
best efforts to cause each person who is so identified as an "affiliate" to
deliver to COFI, as soon as practicable thereafter, a written agreement,
substantially in the form of Exhibit E, providing that from the date of such
agreement each such person will agree not to sell, pledge, transfer or otherwise
dispose of any shares of stock of RCSB held by such person or any shares of COFI
Common Stock to be received by such person in the Company Merger (i) during the
period commencing 30 days prior to the Company Merger and ending at the time of
publication of financial results covering at least 30 days of combined
operations after the Company Merger and (ii) at any time, except in compliance
with the applicable provisions of the Securities Act and other applicable laws
and regulations. Prior to the Effective Time, RCSB shall amend and supplement
such letter and use its best efforts to cause each additional person who is
identified as an "affiliate" to execute a written agreement as set forth in this
Section 5.3. COFI shall deliver to RCSB within five (5) business days after the
date hereof a certified copy of the minutes of a meeting of the Board of
Directors of COFI at which the restrictions on resales of COFI Common Stock
under the pooling of interests method of accounting rules were discussed.

         5.4 EXPENSES. Each party hereto shall bear its own expenses incident to
preparing, entering into and carrying out this Agreement and to consummating the
Merger.

         5.5 COOPERATION. Each party agrees that it will use its best efforts to
bring about the transactions contemplated by this Agreement as soon as
practicable, unless this Agreement is terminated as provided herein. Subject to
the terms and conditions herein provided, each of the parties hereto agrees to
use all reasonable efforts to take, or cause to be taken, all action, and to do,
or cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate and make effective the transactions
contemplated by this Agreement at the earliest practicable time. In case at any
time after the Effective Time any further action is necessary or desirable to
carry out the purposes of this Agreement, the proper officers and/or directors
of the parties, shall take all such necessary action. Each party shall use its
reasonable best efforts to preserve for itself and the other parties hereto each
available legal privilege with

                                       51


<PAGE>



respect to the confidentiality of their negotiations and related communications,
including the attorney-client privilege.

         5.6 REGULATORY APPLICATIONS. The parties shall, as soon as practicable
after the date of this Agreement, file all necessary applications with all
applicable regulatory authorities, and shall use their best efforts to respond
as promptly as practicable to all inquiries received concerning said
applications. In the event the Merger is challenged or opposed by any
administrative or legal proceeding, whether by the United States Department of
Justice or otherwise, the determination of whether and to what extent to seek
appeal or review, administrative or otherwise, or other appropriate remedies
shall be made by COFI after consultation with RCSB. The party filing an
application shall deliver a copy thereof to the other parties hereto in advance
of filing and copies of all responses from or written communications from
regulatory authorities relating to the Merger or this Agreement (to the extent
permitted by law), and the filing party shall also deliver a final copy of each
regulatory application to the other parties promptly after it is filed with the
appropriate regulatory authority. Each party shall advise the other parties
periodically of the status of each regulatory application.

         5.7 FINANCIAL STATEMENTS AND REPORTS. From the date of this Agreement
and prior to the Effective Time: (a) RCSB will deliver to COFI not later than
forty-five (45) days after the end of any calendar quarter, the Report of
Condition and Income filed by Target Bank with the Department and FDIC; (b) COFI
and RCSB shall deliver to each other not later than forty-five (45) days after
the end of each fiscal quarter, its Report on Form 10-Q for such quarter as
filed with the SEC which shall be prepared in conformity with generally accepted
accounting principles and the rules and regulations of the SEC; and (c) each
party will deliver to the others any and all other material reports filed with
the SEC, FDIC, OTS, Department or any other regulatory agency within five (5)
business days of the filing of any such report.

         5.8 NOTICE. At all times prior to the Effective Time, each party shall
promptly notify the others in writing of the occurrence of any event which will
or may result in the failure to satisfy any of the conditions specified in
Sections 6.1 or 6.2 hereof. In the event that any party becomes aware of the
occurrence or impending occurrence of any event which would constitute or cause
a breach by it of any of its representations and warranties, covenants or
agreements herein in any material respect, or would have constituted or caused a
breach by it of its representations and warranties, covenants or agreements
herein in any respect, had such an event occurred or been known prior to the
date hereof, said party shall immediately give detailed and written notice
thereof to the other parties, and shall, unless the same has been waived in
writing by the other parties, use its reasonable efforts to remedy the same
within 30 days, provided that such efforts, if not successful, shall not be
deemed to satisfy any condition precedent to the Merger.

         5.9 PRESS RELEASE.  Except as provided in Section 4.1(g) or as 
otherwise reasonably determined by a party to comply with its legal obligations,
at all times prior to the Effective Time, the parties shall mutually agree to
the issuance of any press release or other information to the

                                       52


<PAGE>



press or any third party for general circulation with respect to this Agreement
or the transactions contemplated hereby.

         5.10 DELIVERY OF SUPPLEMENTS TO DISCLOSURE SCHEDULES. Five business
days prior to the Effective Time, each party will supplement or amend its
Disclosure Schedule with respect to any matter hereafter arising which, if
existing or occurring at or prior to the date of this Agreement, would have been
required to be set forth or described in such Disclosure Schedule or which is
necessary to correct any information in the Disclosure Schedule or in any
representation and warranty made by the disclosing party which has been rendered
inaccurate thereby. For purposes of determining the accuracy of the
representations and warranties of COFI and Charter One Bank, and RCSB and Target
Bank contained, respectively, in Articles II and III hereof in order to
determine the fulfillment of the conditions set forth in Section 6.1(a) and
6.2(a) hereof as of the date of this Agreement, the Disclosure Schedule of each
party shall be deemed to include only that information contained therein on the
date it is initially delivered to the other party together with any nonmaterial
information that was inadvertently left out of a party's Disclosure Schedule as
initially delivered and is subsequently provided in writing as soon as
practicable after the omission is discovered by the disclosing party.

         5.11 LITIGATION MATTERS.  RCSB and Target Bank will consult with COFI 
about any proposed settlement, or any disposition of, any litigation involving
settlement amounts in excess of $50,000.

         5.12 TAX OPINION. COFI agrees to obtain a written opinion of Silver,
Freedman & Taff, L.L.P., addressed to COFI and RCSB, dated the Closing Date,
subject to the representations and assumptions referred to therein, and
substantially to the effect that the Company Merger will constitute a tax-free
reorganization within the meaning of Section 368(a) of the Code and that COFI,
Charter Michigan and RCSB will each be a party to a reorganization.

         5.13 CONTINUING EMPLOYEES. To the extent permitted by applicable law,
the former employees of RCSB and RCSB Subsidiaries who become employees of
Charter One Bank or any other COFI Subsidiary (the "Continuing Employees") shall
continue to participate in the RCSB Benefit Plans, except where any such Plan is
terminated at request of COFI prior to or at the Effective Time. At or after the
Effective Time, COFI may merge any RCSB Benefit Plan with and into an COFI
Benefit Plan or merge an COFI Benefit Plan with and into an RCSB Benefit Plan.
At or after the Effective Time, COFI or any COFI Subsidiary may amend or
terminate any RCSB Benefit Plan, provided, that if the termination or amendment
adversely affects the benefits provided to the Continuing Employees, Charter One
Bank or another COFI Subsidiary shall provide the Continuing Employees with
benefits that are substantially equivalent to the benefits being received by
other similarly situated employees of Charter One Bank or such other COFI
Subsidiary under comparable plans then in effect, if any. Whenever a Continuing
Employee becomes a participant in an COFI Benefit Plan, such Continuing Employee
shall receive full credit for his past service with RCSB or any RCSB Subsidiary
for purposes of determining eligibility to participate in and the vesting of
benefits under such COFI Benefit Plan (but not for the purpose

                                       53


<PAGE>



of accrual of benefits thereunder). Continuing Employees will not be subject to
any exclusion or penalty for pre-existing conditions that were covered under the
RCSB health plan immediately prior to the Effective Time or any waiting period
relating to coverage under the COFI health plan.

         5.14 RESERVATION OF SHARES TO SATISFY RCSB STOCK OPTIONS. COFI shall
take all corporate action necessary to reserve for issuance a sufficient number
of shares of COFI Common Stock for delivery upon exercise of RCSB Stock Options
assumed by it in accordance with Section 1.3(e) hereof. As soon as practicable
after the Effective Time, COFI shall file an appropriate registration statement
with respect to the shares of COFI Common Stock subject to such options and
shall use its best efforts to maintain the effectiveness of such registration
statement or registration statements (and maintain the current status of the
prospectus or prospectuses contained therein) for so long as such options remain
outstanding.

         5.15 NASDAQ LISTING. COFI shall use all reasonable efforts to cause the
shares of COFI Common Stock to be issued in the Company Merger, and the shares
of COFI Common Stock to be reserved for issuance upon exercise of RCSB Stock
Options, to be approved for listing on the Nasdaq Stock Market (or such other
national securities exchange or stock market on which the COFI Common Stock
shall then be traded), subject to official notice of issuance, prior to or as of
the Closing.

         5.16 DIRECTORS' AND OFFICERS' INDEMNIFICATION INSURANCE. For a period
of six years following the Effective Time, COFI shall indemnify, defend and hold
harmless the present and former directors, officers and employees of RCSB and
the RCSB Subsidiaries (each, an "Indemnified Party") against all costs or
expenses (including reasonable attorneys' fees), judgments, fines, losses,
claims, damages or liabilities incurred in connection with any claim, action,
suit, proceeding or investigation, whether civil, criminal, administrative or
investigative, and arising out of matters existing or occurring at or prior to
the Effective Time (including the transactions contemplated by this Agreement
and the agreements executed pursuant to this Agreement), whether asserted or
claimed prior to, at or after the Effective Time, to the fullest extent that
RCSB would have been permitted under Delaware law and its Certificate of
Incorporation or Bylaws in effect on the date of this Agreement to indemnify
such person (and COFI will also advance expenses as incurred to the fullest
extent permitted under applicable law so long as the person to whom expenses are
advanced provides an undertaking to repay such advances if it is ultimately
determined that such person is not entitled to indemnification); PROVIDED
HOWEVER, that (a) any determination required to be made with respect to whether
a person's conduct complies with the standards set forth under Delaware law and
RCSB's Certificate of Incorporation and Bylaws shall be made by independent
counsel mutually agreed upon between COFI and the Indemnified Party, and (b)
COFI shall be obligated pursuant to this Section 5.16 to pay for only one firm
of counsel for all Indemnified Parties, unless an Indemnified Party shall have
reasonably concluded, based on the advice of counsel, that in order to be
adequately represented, separate counsel is necessary for such Indemnified
Party, in which case COFI shall be obligated to pay for such separate counsel.
COFI shall cause the persons serving as officers and directors of RCSB and the
RCSB Subsidiaries immediately prior to the Effective

                                       54


<PAGE>



Time to be covered for a period of six years following the Effective Time by the
directors' and officers' liability insurance policy maintained by COFI and
Charter One Bank (provided that COFI may substitute or cause RCSB to substitute
therefor single premium tail coverage with a policy limit equal to RCSB's
existing annual coverage limit) with respect to acts or omissions occurring
prior to the Effective Time which were committed by such officers and directors
in their capacity as such, provided that the additional premium cost to COFI
does not exceed 200% of RCSB's present annual premium cost (the "Maximum
Amount") and that the insurance is available. If the amount of the premium
necessary to maintain or procure such coverage exceeds the Maximum Amount, COFI
shall use all reasonable efforts to maintain the most advantageous policies of
directors' and officers' insurance obtainable for a premium equal to the Maximum
Amount.

         5.17. EXTRAORDINARY COFI DIVIDENDS. Between the date of this Agreement
and the Effective Time or the termination of this Agreement (whichever occurs
first), COFI shall not declare, set aside or pay any extraordinary dividend or
make any other extraordinary distribution (other than a stock dividend) with
respect to COFI Common Stock.

                                   ARTICLE VI

                                   CONDITIONS

         6.1 CONDITIONS TO THE OBLIGATIONS OF COFI, CHARTER MICHIGAN AND CHARTER
ONE BANK. Notwithstanding any other provision of this Agreement, the obligations
of COFI, Charter Michigan and Charter One Bank to consummate the Merger are
subject to the following conditions precedent (except as to those which COFI may
chose to waive):

                  (a) subject to the cure provisions set forth in Section 5.8,
         all of the representations and warranties made by RCSB and Target Bank
         in this Agreement and in any documents or certificates provided by RCSB
         and Target Bank shall have been true and correct in all material
         respects as of the date of this Agreement and as of the Effective Time
         (after giving effect to the Disclosure Supplements delivered by RCSB
         pursuant to Section 5.10 relating to intervening events) as though made
         on and as of the Effective Time;

                  (b) subject to the cure provisions set forth in Section 5.8,
         RCSB and Target Bank shall have performed in all material respects all
         obligations and shall have complied in all material respects with all
         agreements and covenants required by this Agreement to be performed or
         complied with by them prior to or at the Effective Time;

                  (c) there shall not have been any action taken or any statute,
         rule, regulation or order enacted, promulgated or issued or deemed
         applicable to the Merger by any federal or state government or

                         TERMINATION; AMENDMENT; WAIVER

         7.1  TERMINATION.  This Agreement may be terminated at any time
prior to the Effective Time:

                  (a) By the mutual written consent of the Boards of Directors
         of COFI and RCSB;

                  (b) At any time prior to the Effective Time, by COFI or RCSB
         if there shall have been a final judicial or regulatory determination
         (as to which all periods for appeal shall have expired and no appeal
         shall be pending) that any material provision of this Agreement is
         illegal, invalid or unenforceable (unless the enforcement thereof is
         waived by the affected party) or denying any regulatory application the
         approval of which is a condition precedent to a party's obligations
         hereunder;

                  (c)  At any time on or before the date specified in 7.1(e) 
         hereof, by COFI or RCSB in the event that any of the conditions
         precedent to the obligations of the other

                                       58


<PAGE>



         party to the Merger are rendered impossible to be satisfied or
         fulfilled by said date (other than by reason of a breach by the party
         seeking to terminate);

                  (d) By COFI or RCSB, in the event of a material breach by the
         other party of any representation, warranty, covenant or agreement
         contained herein or in any schedule or document delivered pursuant
         hereto, which breach would result in the failure to satisfy the closing
         condition set forth in Section 6.1(a) or 6.1(b) in the case of COFI, or
         Section 6.2(a) or 6.2(b) in the case of RCSB, and which breach cannot
         be or is not cured within thirty (30) days after written notice of such
         breach is given by the non-breaching party to the party committing such
         breach; or

                  (e) By COFI or RCSB on or after December 31, 1997, in the
         event the Company Merger has not been consummated by such date
         (provided that the terminating party is not then in material breach of
         any representation, warranty, covenant or other agreement contained
         herein).

                  In the event a party elects to effect any termination pursuant
         to Section 7.1(b) through 7.1(e) above, it shall give written notice to
         the other party hereto specifying the basis for such termination and
         certifying that such termination has been approved by the vote of a
         majority of the members of its Board of Directors.

         7.2 LIABILITIES AND REMEDIES. In the event that this Agreement is
terminated by a party (the "Aggrieved Party") solely by reason of the willful
and material breach by the other party ("Breaching Party") of any of its
representations or warranties or the material breach by the Breaching Party of
any of its covenants or agreements contained herein then the Aggrieved Party
shall be entitled to such remedies and relief against the Breaching Party as are
available at law or in equity. Moreover, the Aggrieved Party without terminating
this Agreement shall be entitled to specifically enforce the terms hereof
against the Breaching Party in order to cause the Merger to be consummated. Each
party acknowledges that there is not an adequate remedy at law to compensate the
other parties relating to the non-consummation of the Merger. To this end, each
party, to the extent permitted by law, irrevocably waives any defense it might
have based on the adequacy of a remedy at law which might be asserted as a bar
to specific performance, injunctive relief or other equitable relief.

         7.3 SURVIVAL OF AGREEMENTS. In the event of termination of this
Agreement by either COFI or RCSB as provided in Section 7.1, this Agreement
shall forthwith become void and have no effect except that the agreements
contained in Sections 5.1(b), 5.4, and 7.2 hereof shall survive the termination
hereof.

         7.4 AMENDMENT.  This Agreement may be amended by the parties hereto by 
action taken by their respective Boards of Directors at any time before or after
approval hereof by the stockholders of COFI and RCSB but, after such approval,
no amendment shall be made which changes the form of consideration or the value
of the consideration to be received by the stockholders of RCSB without the
approval of the stockholders of COFI and RCSB. This

                                       59


<PAGE>



Agreement may not be amended except by an instrument in writing signed on behalf
of each of the parties hereto. The parties may, without approval of their
respective Boards of Directors, make such technical changes to this Agreement,
not inconsistent with the purposes hereof as may be required to effect or
facilitate any regulatory approval or acceptance of the Merger or of this
Agreement or to effect or facilitate any regulatory or governmental filing or
recording required for the consummation of any of the transactions contemplated
hereby.

         7.5 WAIVER. Any term, provision or condition of this Agreement (other
than the requirement of COFI and RCSB stockholder approval) may be waived in
writing at any time by the party which is entitled to the benefits hereof. Each
and every right granted to any party hereunder, or under any other document
delivered in connection herewith or therewith, and each and every right allowed
it by law or equity, shall be cumulative and may be exercised from time to time.
The failure of a party at any time or times to require performance of any
provision hereof shall in no manner affect such party's right at a later time to
enforce the same. No waiver by any party of a condition or of the breach of any
term, covenant, representation or warranty contained in this Agreement, whether
by conduct or otherwise, in any one or more instances shall be deemed to be or
construed as a further or continuing waiver of any such condition or breach or a
waiver of any other condition or of the breach of any other term, covenant,
representation or warranty of this Agreement. No investigation, review or audit
by a party of another party prior to or after the date hereof shall estop or
prevent such party form exercising any right hereunder or be deemed to be a
waiver of any such right.

                                  ARTICLE VIII

                               GENERAL PROVISIONS

         8.1 SURVIVAL. All representations, warranties, covenants and agreements
of the parties in this Agreement or in any instrument delivered by the parties
pursuant to this Agreement (other than the agreements, covenants and obligations
set forth herein which are contemplated to be performed after the Effective
Time) shall not survive the Effective Time, provided that no such
representations, warranties or covenants shall be deemed to be terminated or
extinguished so as to deprive any party (or any of its directors, officers,
employees or agents) of any defense in law or equity which otherwise would be
available against the claims of any person, including, without limitation, any
stockholder or former stockholder of either COFI or RCSB, the aforesaid
representations, warranties, and covenants being material inducements to
consummation by the parties and the surviving corporation and resulting
institution of the transactions contemplated hereby.

         8.2 NOTICES. All notices and other communications hereunder shall be in
writing and shall be deemed given if delivered personally, by facsimile
transmission or by registered or certified mail to the parties at the following

notice) and shall be deemed to be delivered on the date so delivered:

         4.       Payment and Delivery of Certificates.
                  ------------------------------------

         (a) At the closing referred to in Section 3 hereof, COFI shall pay to
RCSB the aggregate Purchase Price for the shares of RCSB Common Stock purchased
pursuant to the exercise of the Option in immediately available funds by wire
transfer to a bank account designated by RCSB.

         (b) At such closing, simultaneously with the delivery of cash as
provided in Section 4(a), RCSB shall deliver to COFI a certificate or
certificates representing the number of shares of RCSB Common Stock purchased by
COFI, registered in the name of COFI or a nominee designated in writing by COFI,
and COFI shall deliver to RCSB a letter agreeing that COFI shall not offer to
sell, pledge or otherwise dispose of such shares in violation of applicable law
or the provisions of this Option Agreement.

         (c) If at the time of issuance of any RCSB Common Stock pursuant to any
exercise of the Option, RCSB shall have issued any share purchase rights or
similar securities to holders of RCSB Common Stock, then each such share of RCSB
Common Stock shall also represent rights with terms substantially the same as
and at least as favorable to COFI as those issued to other holders of RCSB
Common Stock.

         (d) Certificates for RCSB Common Stock delivered at any closing
hereunder shall be endorsed with a restrictive legend which shall read
substantially as follows:

         The transfer of the shares represented by this certificate is subject
         to certain provisions of an agreement between the registered holder
         hereof and RCSB Financial, Inc. dated May 21, 1997, a copy of which is
         on file at the principal office of RCSB Financial, Inc., and to resale
         restrictions arising under the Securities Act of 1933 and any
         applicable state securities laws. A copy of such agreement will be
         provided to the holder hereof without charge upon receipt by RCSB
         Financial, Inc. of a written request therefor.

It is understood and agreed that the above legend shall be removed by delivery
of substitute certificate(s) without such legend if COFI shall have delivered to
RCSB an opinion of counsel, in

                                        5


<PAGE>



form and substance reasonably satisfactory to RCSB and its counsel, to the
effect that such legend is not required for purposes of the Securities Act and
any applicable state securities laws.

         and, at all times from the date hereof through the date of the exercise
         in full or the expiration or termination of the Option, shall have
         reserved for issuance upon exercise of the Option, 2,880,944 shares of
         RCSB Common Stock, all of which, upon issuance pursuant hereto, shall

                  (i) COFI has full corporate authority to execute and deliver
         this Option Agreement and, subject to Section 11(i), to consummate the

         6.       Adjustment upon Changes in Capitalization.
                  -----------------------------------------

         In the event of any change in RCSB Common Stock by reason of dividends,
split-ups, recapitalizations or the like, the type and number of shares subject

adjusted appropriately. In the event that any additional shares of RCSB Common
Stock are issued after the date of this Option Agreement (other than pursuant to
an event described in the preceding sentence or pursuant to this Option
Agreement), the number of shares of RCSB Common Stock subject to the Option
shall be adjusted so that, after such issuance, it equals at least 19.9% of the
number of shares of RCSB Common Stock then issued and outstanding (without
considering any shares subject to or issued pursuant to the Option).

         7.       Repurchase.
                  ----------

         (a) Subject to Section 11(i), at the request of COFI at any time
commencing upon the occurrence of a Purchase Event and ending 13 months
immediately thereafter (the "Repurchase Period"), RCSB (or any successor entity
thereof) shall repurchase the Option from COFI together with all (but not less
than all, subject to Section 10) shares of RCSB Common Stock purchased by COFI
pursuant thereto with respect to which COFI then has Beneficial Ownership, at a
price (per share, the "Per share Repurchase Price") equal to the sum of:

                  (i)  The exercise price paid by COFI for any shares of RCSB 
         Common Stock acquired pursuant to the Option;

                  (ii) The difference between (A) the "Market/Tender Offer
         Price" for shares of RCSB Common Stock (defined as the higher of (x)
         the highest price per share at which a tender or exchange offer has
         been made for shares of RCSB Common Stock or (y) the highest closing
         mean of the "bid" and the "ask" price per share of RCSB Common Stock
         reported by the Nasdaq, the automated quotation system of the National
         Association of Securities Dealers, Inc., for any day within that
         portion of the Repurchase Period which precedes the date COFI gives
         notice of the required repurchase under this Section 7) and (B) the
         exercise price as determined pursuant to Section 2 hereof (subject to
         adjustment as provided in Section 6), multiplied by the number of
         shares of RCSB Common Stock with respect to which the Option has not
         been exercised, but only if the Market/Tender Offer Price is greater
         than such exercise price; and

                  (iii) The difference between the Market/Tender Offer Price and
         the exercise price paid by COFI for any shares of RCSB Common Stock
         purchased pursuant to the exercise of

                                        8


<PAGE>



         the Option, multiplied by the number of shares so purchased, but only
         if the Market/Tender Offer Price is greater than such exercise price.

         (b)      In the event COFI exercises its rights under this Section 7, 
RCSB shall, within ten business days thereafter, pay the required amount to COFI
by wire transfer of immediately available funds to an account designated by COFI
and COFI shall surrender to RCSB the Option and the certificates evidencing the
shares of RCSB Common Stock purchased thereunder with respect to which COFI then
has Beneficial Ownership, and COFI shall warrant that it has sole record and
Beneficial Ownership of such certificates and that the same are free and clear
of all liens, claims, charges, restrictions and encumbrances of any kind
whatsoever.

         (c) In determining the Market/Tender Offer Price, the value of any
consideration other than cash shall be determined by an independent nationally
recognized investment banking firm selected by COFI and reasonably acceptable to
RCSB.

         8.       Repurchase at Option of RCSB and First Refusal.
                  ----------------------------------------------

         (a) Except to the extent that COFI shall have previously exercised its
rights under Section 7, at the request of RCSB during the six-month period
commencing 13 months following the first occurrence of a Purchase Event, RCSB
may repurchase from COFI, and COFI shall sell to RCSB, all (but not less than
all, subject to Section 10) of the RCSB Common Stock acquired by COFI pursuant
hereto and with respect to which COFI has Beneficial Ownership at the time of
such repurchase at a price per share equal to the greater of (i) 110% of the
Market/Tender Offer Price per share, (ii) the Per Share Repurchase Price or
(iii) the sum of (A) the aggregate Purchase Price of the shares so repurchased
plus (B) interest on the aggregate Purchase Price paid for the shares so
repurchased from the date of purchase to the date of repurchase at the highest
rate of interest announced by COFI Bank as its prime or base lending or
reference rate during such period, less any

                                        9


<PAGE>



dividends received on the shares so repurchased, plus (C) COFI's reasonable
out-of-pocket expenses incurred in connection with the transactions contemplated
by the Merger Agreement, including, without limitation, legal, accounting and
investment banking fees. Any repurchase under this Section 8(a) shall be
consummated in accordance with Section 7(b).

         (b) If, at any time after the occurrence of a Purchase Event and prior
to the earlier of (i) the expiration of 18 months immediately following such
Purchase Event or (ii) the expiration or termination of the Option, COFI shall
desire to sell, assign, transfer or otherwise dispose of the Option or all or
any of the shares of RCSB Common Stock acquired by it pursuant to the Option, it
shall give RCSB written notice of the proposed transaction (an "Offeror's
Notice"), identifying the proposed transferee, and setting forth the terms of
the proposed transaction. An Offeror's Notice shall be deemed an offer by COFI
to RCSB, which may be accepted within five business days of the receipt of such
Offeror's Notice, on the same terms and conditions and at the same price at
which COFI is proposing to transfer the Option or such shares to a third party.
The purchase of the Option or any such shares by RCSB shall be closed within
five business days of the date of the acceptance of the offer and the purchase
price shall be paid to COFI by wire transfer of immediately available funds to
an account designated by COFI. In the event of the failure or refusal of RCSB to
purchase the Option or all the shares covered by the Offeror's Notice or if any
regulatory authority disapproves RCSB's proposed purchase of the Option or such
shares, COFI may, within 60 days from the date of the Offeror's Notice, sell
all, but not less than all, of the Option or such shares to such third party at
no less than the price specified and on terms no more favorable to the purchaser
than those set forth in the Offeror's Notice. The requirements of this Section
8(b) shall not apply to (i) any disposition as a result of which the proposed
transferee would Beneficially Own not more than 2%

                                       10


<PAGE>



of the voting power of RCSB or (ii) any disposition of RCSB Common Stock by a
person to whom COFI has sold RCSB Common Stock issued upon exercise of the
Option.

         9.       Registration Rights.
                  -------------------

         At any time after a Purchase Event, RCSB shall, if requested by any
holder or beneficial owner of shares of RCSB Common Stock issued upon exercise
of the Option (except any beneficial holder who acquired all of such holder's
shares in a transaction exempt from the requirements of Section 8(b) by reason
of clause (i) thereof) (each a "Holder"), as expeditiously as possible file a
registration statement on a form for general use under the Securities Act if
necessary in order to permit the sale or other disposition of the shares of RCSB
Common Stock that have been acquired upon exercise of the Option in accordance
with the intended method of sale or other disposition requested by any such
Holder (it being understood and agreed that any such sale or other disposition
shall be effected on a widely distributed basis so that, upon consummation
thereof, no purchaser or transferee shall Beneficially Own more than 2% of the
shares of RCSB Common Stock then outstanding). Each such Holder shall provide
all information reasonably requested by RCSB for inclusion in any registration
statement to be filed hereunder. RCSB shall use its best efforts to cause such
registration statement first to become effective and then to remain effective
for such period not in excess of 180 days from the day such registration
statement first becomes effective as may be reasonably necessary to effect such
sales or other dispositions. The registration effected under this Section 9
shall be at RCSB's expense except for underwriting commissions and the fees and
disbursements of such Holders' counsel attributable to the registration of such
RCSB Common Stock. In no event shall RCSB be required to effect more than one
registration hereunder. The filing of the registration statement hereunder may
be delayed for such period of time as may reasonably be required to facilitate
any public distribution by RCSB of RCSB Common Stock or if a special

                                       11


<PAGE>



audit of RCSB would otherwise be required in connection therewith. If requested
by any such Holder in connection with such registration, RCSB shall become a
party to any underwriting agreement relating to the sale of such certificates,
but only to the extent of obligating itself in respect of representations,
warranties, indemnities and other agreements customarily included in such
underwriting agreements for parties similarly situated. Upon receiving any
request for registration under this Section 9 from any Holder, RCSB agrees to
send a copy thereof to any other person known to RCSB to be entitled to
registration rights under this Section 9, in each case by promptly mailing the
same, postage prepaid, to the address of record of the persons entitled to
receive such copies.

         10.      Severability.
                  ------------

         Any term, provision, covenant or restriction contained in this Option
Agreement held by a court or a regulatory authority of competent jurisdiction to
be invalid, void or unenforceable, shall be ineffective to the extent of such
invalidity, voidness or unenforceability, but neither the remaining terms,
provisions, covenants or restrictions contained in this Option Agreement nor the
validity or enforceability thereof in any other jurisdiction shall be affected
or impaired thereby. Any term, provision, covenant or restriction contained in
this Option Agreement that is so found to be so broad as to be unenforceable
shall be interpreted to be as broad as is enforceable. If for any reason such
court or regulatory authority determines that applicable law will not permit
COFI or any other person to acquire, or RCSB to repurchase or purchase, the full
number of shares of RCSB Common Stock provided in Section 2 hereof (as adjusted
pursuant to Section 6 hereof), it is the express intention of the parties hereto
to allow COFI or such other person to acquire, or RCSB to repurchase or
purchase, such lesser number of shares as may be permissible, without any
amendment or modification hereof.

assigns, any rights, remedies, obligations, or liabilities under or by reason of
this Option Agreement, except as expressly provided herein.

         (f) COUNTERPARTS. This Option Agreement may be executed in
counterparts, and each such counterpart shall be deemed to be an original
instrument, but both such counterparts together shall constitute but one
agreement.

         (g) SPECIFIC PERFORMANCE. The parties hereto agree that if for any
reason COFI or RCSB shall have failed to perform its obligations under this

Agreement against such non-performing party shall be entitled to specific
performance and injunctive and other equitable relief, and the parties hereto
further agree to waive any requirement for the securing or posting of any bond
in connection with the obtaining of any such injunctive or other equitable
relief. This provision is without prejudice to any other rights that either
party hereto may have against the other party hereto for any failure to perform
its obligations under this Option Agreement.

         (h) GOVERNING LAW. This Option Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware applicable to
agreements made and entirely to be performed within such state. Nothing in this
Option Agreement shall be construed to require any party (or any subsidiary or
affiliate of any party) to take any action or fail to take any action in
violation of applicable law, rule or regulation.

         (i) REGULATORY APPROVALS; SECTION 16(b). If, in connection with (A) the
exercise of the Option under Section 3 or a sale by COFI to a third party under
Section 8, (B) a repurchase by RCSB under Section 7 or a repurchase or purchase
by RCSB under Section 8, prior notification to or approval of the OTS or any
other regulatory authority is required, then the required notice or application
for approval shall be promptly filed and expeditiously processed and periods of
time that otherwise would run pursuant to such Sections shall run instead from
the date on which any such required notification period has expired or been
terminated or such approval has been obtained, and

                                       14

in either event, any requisite waiting period shall have passed. In the case of
clause (A) of this subsection (i), such filing shall be made by COFI, and in the
case of clause (B) of this subsection (i), such filing shall be made by RCSB,
provided that each of COFI and RCSB shall use its best efforts to make all
filings with, and to obtain consents of, all third parties and Regulatory
Authorities necessary to the consummation of the transactions contemplated
hereby. Periods of time that otherwise would run pursuant to Sections 3, 7 or 8
shall also be extended to the extent necessary to avoid liability under Section
16(b) of the Exchange Act.

         (j) NO BREACH OF AGREEMENT AUTHORIZED.  Nothing contained in this 
Option Agreement shall be deemed to authorize RCSB to issue any shares of RCSB
Common Stock in breach of, or otherwise breach any of, the provisions of the
Merger Agreement.

         (k) WAIVER AND AMENDMENT. Any provision of this Agreement may be waived
at any time by the party that is entitled to the benefits of such provision.
This Option Agreement may not be modified, amended, altered or supplemented
except upon the execution and delivery of a written agreement executed by the
parties hereto.

                                       15
