                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 2001



NOTE A - FINANCIAL STATEMENTS

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial  information and with the  instructions to Form 10-Q and Article 10 of
Regulation  S-X.  Accordingly,  they do not include all of the  information  and
footnotes  required by generally  accepted  accounting  principles  for complete
financial statements. In the opinion of management,  all adjustments (consisting
of normal recurring accruals)  considered necessary for a fair presentation have
been included.  Operating  results for the six month period ended June 30, 2001,
are not necessarily  indicative of the results that may be expected for the year
ending  December 31,  2001.  The balance  sheet at December  31, 2000,  has been
derived  from  the  audited  financial  statements  at that  date.  For  further
information,  refer  to the  consolidated  financial  statements  and  footnotes
thereto  included in the  Corporation's  annual report on Form 10-K for the year
ended December 31, 2000.


NOTE B - SECURITIES

Individual   securities  held  in  the  security  portfolio  are  classified  as
securities available for sale. Securities might be sold prior to maturity due to
changes in interest rates,  prepayment risks,  yield,  availability of alternate
investments,   liquidity  needs  or  other  factors.  Securities  classified  as
available  for sale are reported at their fair value and the related  unrealized
holding  gain or loss is  reported,  net of  related  income tax  effects,  as a
separate component of shareholders' equity until realized.


NOTE C - LOAN COMMITMENTS

Loan  commitments  (including  unused lines of credit and letters of credit) are
made to accommodate the financial needs of the Banks' customers. The commitments
have credit risk  essentially  the same as that  involved in extending  loans to
customers,  and are subject to the Banks' normal credit  policies and collateral
requirements.  Loan commitments, which are predominately at variable rates, were
approximately  $95,456,000  and  $88,264,000  at June 30, 2001, and December 31,
2000, respectively.

Item 2.  Management' s Discussion and Analysis of Financial Condition and
         Results of Operations.


The consolidated  financial  information  presented is for Firstbank Corporation
("Corporation") and its wholly owned subsidiaries,  Firstbank - Alma,  Firstbank
(Mt. Pleasant),  Firstbank - West Branch (including its majority holding in C.A.
Hanes Realty, Inc.),  Firstbank - Lakeview,  Firstbank - St. Johns (collectively
the "Banks") and Gladwin Land Company.


Financial Condition

Total assets showed  little  change,  decreasing $5 million,  or .65% during the
first six months of 2001. Cash and cash  equivalents  decreased by $1.3 million,
or 4.5%,  during the first six  months of 2001.  Securities  available  for sale
declined $5 million,  or 6.3%,  during the six months ended June 30, 2001.  This
decrease was more than matched by decreases in  borrowings  (see below).  Nearly
all of this decrease was accomplished by decisions not to fully replace maturing
securities.

Total  loans grew $1.5  million,  or .25%,  during  the first half of 2001.  The
commercial  portfolio  grew $12.7 million and loans held for sale increased $1.5
million,  but this growth was partially offset by decreases in both mortgage and
consumer loans of $9.6 million and $3.0 million, respectively. The allowance for
loan losses increased $307,000,  or 3.1%, during the first half of 2001. At June
30, 2001, the allowance as a percent of outstanding  loans was 1.69% compared to
1.64% at December 31, 2000.  The allowance as a percent of  nonperforming  loans
was 582% at the end of the  second  quarter  of 2001 and 462% at year end  2000.
During the first six months of 2001,  the allowance was increased by a provision
of $431,000 and decreased by net charge offs of $124,000.  Management  continues
to maintain the allowance for loan losses at a level  considered  appropriate to
absorb losses in the  portfolio.  The  allowance  balance is  established  after
considering past loan loss  experience,  current  economic  conditions,  volume,
growth and composition of the loan portfolio,  delinquencies, and other relevant
factors.

Total deposits increased $9.8 million, or 1.82%, from December 31, 2000, to June
30, 2001.  Reductions in noninterest  bearing  account  balances of $2.1 million
were offset by increases of $9.2 million,  or 6.8%, in interest  bearing  demand
deposits,  $2.3 million,  or 3.3%, in savings  deposits and $0.4 million in time
deposits.

For the six month period ended June 30, 2001,  securities sold under  agreements
to repurchase  and overnight  borrowings  have  decreased by $13.2  million,  or
34.6%.  A portion of the decrease  resulted  from the transfer  from  repurchase
agreements to time deposits noted above.  The increase in time deposits was used
to satisfy  funding  needs  rather  than  borrowings.  Notes  payable  also have
decreased $6.7 million from the end of December 2000, to the end of June,  2001,
as it was not necessary to renew all maturing notes.

                                     Page 10

Total  shareholders'  equity increased $3.7 million,  or 5.8%,  during the first
half of 2001. Net income of  $4,030,000,  stock  issuances of $971,000,  and net
unrealized  appreciation on securities  available for sale of $448,000 increased
shareholders'  equity,  while  stock  repurchases  of $40,000 and  dividends  of
$1,675,000  decreased  shareholders'  equity. Book value was $14.07 per share at
June 30, 2001, and $13.47 at December 31, 2000.

The  following  table  discloses  compliance  with  current  regulatory  capital
requirements on a consolidated basis:

Results of Operations

For the second  quarter of 2001, net income was  $2,418,000,  basic earnings per
share were $0.50,  and diluted  earnings  per share were also $0.50  compared to
$2,140,000,  $0.44, and $0.44 for the second quarter of 2000. Net income for the
first half of 2001 was  $4,030,000  with basic  earnings  per share of $0.84 and
diluted earnings per share of $0.83, compared to $4,250,000, $0.87 and $0.86 for
the first six months of 2000.  Net income for the first half of 2001 was reduced
by a $446,000  one-time  charge  taken in the first  quarter  and  discussed  in
previous  disclosures,  with basic  earnings per share and diluted  earnings per
share also reduced by $0.10 and $0.09 respectively by the one-time charge.

Average earning assets increased $63 million,  or 10.2%,  from the first half of
2000 to the first half of 2001. Despite the sharp decline in short term interest
rates in the first  quarter of 2001,  due to the fact that  interest  rates were
rising in the first half of 2000,  yields and costs of funds were  higher in the
first  half of 2001  compared  to the first  half of 2000.  The yield on earning
assets increased 9 basis points to 8.58% at June 30, 2001,  compared to 8.49% at
June 30, 2000. The cost of funding related liabilities increased 22 basis points
when  comparing  the six month periods ended June 30 from 3.96% in 2000 to 4.18%
in 2001.  Firstbank  Corporation's  funding mix also became  more  costly,  as a
greater  percentage  of funding  shifted to Federal Home Loan Bank  advances and
other borrowings rather than deposits.

Since the  increase  in yields on earning  assets was less than the  increase in
cost of funds,  the net interest  margin declined 14 basis points from 4.70% for
the first half of 2000 to 4.56% for the six months ended June 30, 2001. However,
the net  interest  margin  rebounded  in the  second  quarter  of 2001 to  4.66%
compared to 4.45% in the first quarter of 2001.  Net interest  income  increased
$938,000,  or 6.7%,  in the first half of 2001  compared  to the same  period in
2000.

                                     Page 11

The provision for loan losses  increased  $43,000 to $431,000 for the first half
of 2001  compared  to the  first  half  of  2000.  This  increase  reflects  the
recognition of strong  commercial loan growth over the year-ago level as opposed
to concern over loan quality.

Total noninterest income increased  $1,400,000,  or 52.7%, during the first half
of 2001 when compared to the same period in 2000.  Most of the increase in total
noninterest   income  and  in  other  noninterest  income  was  attributable  to
subsidiaries  which were not in  operation  for all or part of the first half of
2000 (1st Title, C.A. Hanes, Gladwin Land, and Firstbank - St. Johns). Excluding
these  new  subsidiaries  from the 2001 and 2000  periods,  non-interest  income
increased  $581,000,  or 22.7%.  Service charges on deposit  accounts  increased
$88,000,  or 10.6%.  Excluding the new subsidiaries,  service charges on deposit
accounts  increased  $64,000,  or 7.7%. Gain on sale of mortgage loans increased
$786,000,  or 460% due to increased mortgage origination and mortgage re-finance
activity.  None of this increase was due to the new subsidiaries.  Certain other
categories of non-interest  income  declined,  most notably  mortgage  servicing
income which  declined  from $148,000 in the first half of 2000 to $2,000 in the
first half of 2001.  The decline was due to the impact of  refinances  and other
pre-payments.  Excluding these impacts,  mortgage servicing income grew 12.5% to
$341,000  in the first half of 2001  compared  to  $303,000 in the first half of
2000.  Refinances  and other  pre-payments  also were the  primary  cause of the
decline in real estate mortgage  portfolio loans, as many re-financed loans were
sold in the secondary market.

Noninterest expense increased $2,606,000, or 25.6%, when comparing the six month
period ended June 30, 2001 and 2000. Most of the increase in noninterest expense
and its components was attributable to subsidiaries  which were not in operation
for all or part of the first half of 2000,  the  one-time  charges  of  $676,000
taken in the first  quarter of 2001 and discussed in previous  disclosures,  and
employee  benefits  expense - primarily  costs of  providing  medical  benefits.
Excluding the new  subsidiaries,  the one-time  charges,  and employee  benefits
expense, non-interest expenses increased $338,000, or 3.7%.

Analysis of the second  quarter of 2001  compared to the second  quarter of 2000
provides similar observations as comparisons of the half-year periods.

Total noninterest income increased $851,000, or 63.9%, during the second quarter
of 2001 when compared to the same period in 2000.  Most of the increase in total
noninterest   income  and  in  other  noninterest  income  was  attributable  to
subsidiaries  which were not in operation for all or part of the second  quarter
of 2000 (1st Title,  C.A.  Hanes,  Gladwin  Land,  and  Firstbank - St.  Johns).
Excluding these new  subsidiaries  from the 2001 and 2000 periods,  non-interest
income  increased  $366,000,  or 29.6%.  Service  charges  on  deposit  accounts
increased $51,000, or 11.5%. Excluding the new subsidiaries,  service charges on
deposit accounts increased $37,000, or 8.4%. Gain on sale of mortgages increased
$544,000,  or 697% due to increased mortgage origination and mortgage re-finance
activity.  None of this increase was due to the new subsidiaries.  Certain other
categories of non-interest  income  declined,  most notably  mortgage  servicing
income which  declined  from  $69,000 in the second  quarter of 2000 to negative
$39,000 in the  second  quarter of 2001.  The  decline  was due to the impact of
refinances and other pre-payments.

                                     Page 12

Noninterest  expense  increased  $1,060,000,  or 20.9%, when comparing the three
month periods ended June 30, 2001 and 2000.  Most of the increase in noninterest
expense and its components was  attributable to  subsidiaries  which were not in
operation  for all or part of the second  quarter of 2000 and employee  benefits
expense - primarily  costs of  providing  medical  benefits.  Excluding  the new
subsidiaries and employee  benefits  expense,  non-interest  expenses  decreased
$56,000, or 1.2%.

allowances presented in this report are inherently forward-looking statements in
that they  involve  judgements  and  statements  of belief as to the  outcome of

Therefore,  actual results and outcomes may  materially  differ from what may be
expressed  or  forecasted  in  such  forward-looking  statements.  Internal  and
external  factors that may cause such a difference  include  changes in interest
rates and interest rate  relationships;  demand for products and  services;  the
degree of competition by traditional and non-traditional competitors; changes in
banking  regulations;  changes  in tax laws;  changes  in  prices,  levies,  and
assessments;  the impact of technological advances;  governmental and regulatory
policy changes; the outcomes of pending and future litigation and contingencies;

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

Information  under the headings,  "Liquidity and Interest Rate  Sensitivity"  on
page 8 and "Quantitative and Qualitative  Disclosure About Market Risk" on pages
9 through 10 in the  registrant's  annual  report to  shareholders  for the year
ended December 31, 2000, is here incorporated by reference.  Firstbank's  annual
report is filed as Exhibit 13 to its Form 10-K annual report for its fiscal year
ended December 31, 2000.

Firstbank faces market risk to the extent that both earnings and the fair values
of its  financial  instruments  are affected by changes in interest  rates.  The
Corporation manages this risk with static GAP analysis and simulation  modeling.
The  Corporation  does not believe that there has been a material  change in the
nature  of the  Corporation's  primary  market  risk  exposures,  including  the
categories of market risk to which the Corporation is exposed and the particular
markets that present the primary risk of loss to the Corporation. As of the date
of this Form 10-Q Quarterly  Report,  the Corporation does not know of or expect
there to be any material change in the general nature of its primary market risk
exposure in the near term.

The methods by which the Corporation  manages its primary market risk exposures,
as  described  in the sections of its Form 10-K Annual  Report  incorporated  by
reference  in response  to this item,  have not  changed  materially  during the
current year. As of the date of this Form 10-Q quarterly report, the Corporation
does not  expect  to  change  those  methods  in the  near  term.  However,  the
Corporation  may  change  those  methods  in the  future to adapt to  changes in
circumstances or to implement new techniques.

The Corporation's  market risk exposure is mainly comprised of its vulnerability
to interest rate risk. Prevailing interest rates and interest rate relationships
in the future will be primarily  determined by market  factors which are outside
of  Firstbank's  control.  All  information  provided  in  response to this item
consists  of  forward  looking  statements.  Reference  is made  to the  section
captioned  "Forward  Looking  Statements" on page 12 of this Form 10-Q quarterly
report for a discussion of the  limitations  on Firstbank's  responsibility  for
such statements.
