                        FIRSTBANK CORP. AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(1)     BASIS OF PRESENTATION

The accompanying  unaudited consolidated financial statements have been prepared
in accordance with Generally Accepted  Accounting  Principles (GAAP) for interim
financial information and with the instructions to Form 10-QSB and Article 10 of
Regulation  S-X.  Accordingly,  they do not include all of the  information  and
footnotes required by GAAP for complete financial  statements.  These statements
should be read in conjunction with the combined financial statements and related
notes  included the Company's  Form 10-KSB for the year ended March 31, 1997. In
the opinion of  management,  all  adjustments  (consisting  of normal  recurring
adjustments)  necessary for a fair presentation have been included.  The results
of operations and other data for the three-months and six-months ended September
30, 1997 are not necessarily  indicative of results that may be expected for the
entire fiscal year ending March 31, 1998.

The  unaudited  consolidated  financial  statements  of  FirstBank  Corp.  ("the
Company")  include  the  accounts  of  its  wholly-owned  subsidiary,  FirstBank
Northwest  (the  "Savings  Bank")  and  it's  wholly-owned  subsidiary,  TriStar
Financial  Corporation for the  three-months  and six-months ended September 30,
1997.  The financial  statements  for the periods prior to June 30, 1997 include
only the  accounts  of the  Savings  Bank and its  subsidiary.  All  significant
intercompany accounts and transactions have been eliminated in consolidation.

In June 1996, the Financial  Accounting  Standards Board (FASB) issued Statement
of Financial  Accounting  Standards (SFAS) No. 125, "Accounting for Transfer and
Servicing  of  Financial  Assets  and  Extinguishment  of  Liabilities,"   which
supersedes  SFAS No. 122 and  establishes  new  standards  that focus on control
whereas,  after a  transfer  of  financial  assets,  an  entity  recognizes  the
financial  servicing  assets it controls and the  liabilities  it has  incurred,
derecognizes   financial   assets  when  control  has  been   surrendered,   and
derecognizes liabilities when extinguished. This statement applies prospectively
in fiscal years beginning after December 31, 1996.

In December  1996,  the FASB issued SFAS No. 127 "Deferral of the Effective Date
of Certain  Provisions of FASB Statement No. 125," which defers for one year the
effective  date  of  certain   provisions  of  SFAS  125  that  address  secured
borrowings,  collateral for all  transactions  and transfers of financial assets
that  are  part  of  repurchase  agreements,   securities  lending  and  similar
transactions.  The Company does not expect the adoption of SFAS No. 125 and SFAS
No. 127 to have a material effect on its financial statements.

In February  1997,  the FASB issued SFAS No. 128,  "Earnings  per Share,"  which
establishes  standards  for  computing  and  presenting  earnings  per share and
applies to entities with  publicly held common stock or potential  common stock.
This statement is effective for financial  statements  ending after December 15,
1997.  The Company  does not expect  adoption  to have a material  effect on its
financial statements.

In February 1997, the FASB issued SFAS No. 129. "Disclosure of Information about
Capital  Structure" which clarifies  disclosure rules about such items as rights
and  privileges  of  debt  and  equity  securities,   dividend  and  liquidation
preferences,  participation  rights  and  call  prices.  It  also  demands  that
liquidation  preferences  be  shown  on the  face  of the  balance  sheet.  This
statement is effective for financial  statements ending after December 31, 1997.
The Company does not expect  adoption to have a material effect on its financial
statements.

In June 1997, the FASB issued SFAS No. 130,  "Reporting  Comprehensive  Income,"
which  requires  the  disclosure  of  comprehensive   income  and  requires  the
presentation of a  reconciliation  for net income to the change in equity of the
business during the year arising due to transactions from nonowner sources. This
statement is effective for financial  statements  beginning  after  December 15,
1997.  The Company  does not expect  adoption  to have a material  effect on its
financial statements.

(2)  CONVERSION TO STOCK OWNERSHIP

On  January  8, 1997 the Board of  Directors  of the  Savings  Bank  unanimously
adopted a Plan of Conversion pursuant to which the Savings Bank converted from a
federally  chartered mutual savings bank to a federally  chartered stock savings
bank,  with the  concurrent  formation of the Company.  The Company,  on July 1,
1997,  sold 1,983,750  shares of common stock at $10.00 per share to depositors,
borrowers and employees of the Savings Bank and an internally leveraged employee
stock ownership plan in a subscription offering. From the proceeds,  $19,838 was
allocated  to  common  stock  based  on a  par  value  of  $.01  per  share  and
$18,921,825,  which is net of  conversion  costs of $895,837,  was  allocated to
additional paid in capital.


                                                                               5

(3)  EARNINGS PER SHARE

Earnings per common share were computed by the weighted  number of common shares
outstanding,  which was  1,825,050  at  September  30,  1997.  Only ESOP  shares
allocated and committed to be released are considered  outstanding  for purposes
of computing earnings per common share. No shares were outstanding prior to July
1, 1997,  therefore  earnings per common  share for those  periods have not been
presented.

(4)  EMPLOYEE STOCK OWNERSHIP PLAN ("ESOP")

During 1997 the Company established a tax-qualified  internally  leveraged ESOP.
The ESOP covers  substantially all employees who have attained the age of 21 and
completed  one year of service.  In  connection  with the  conversion to a stock
company,  the ESOP purchased  158,700 shares of the Company's  common stock at a
price of $10.00 per share using funds loaned by the Company. All ESOP shares are
held in a suspense  account and are allocated  among the  participants  on a pro
rata basis as the loan is repaid.  Currently  this  receivable  from the ESOP is
scheduled to be repaid with level principal and interest  payments over 15 years
with no penalty for prepayment.  Shares  released from the suspense  account are
allocated among the participants based upon their pro rata annual compensation.

The sale of the shares to the ESOP was recorded by the Company as unearned  ESOP
shares, a contra equity account.  As ESOP shares are committed to be released to
compensate  employees,  the contra equity account is reduced and a corresponding
charge to  compensation  expense  equal to the fair  market  value of the shares
committed  to be  released  is  recorded.  Upon  committing  these  share  to be
released,   they  become   outstanding   for   purposes  of   earnings-per-share
computations.  Dividends on allocated ESOP shares are recorded as a reduction of
retained  earnings;  dividends  on  unallocated  ESOP  shares  are  recorded  as
compensation  expense.  Compensation expense related to the ESOP was $66,641 for
the six months ended  September  30, 1997.  The ESOP shares as of September  30,
1997 were as follows:

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Forward-looking statements,  within the meaning of Section 21E of the Securities
and Exchange Act of 1934, are made throughout this  Management's  Discussion and
Analysis of Financial Condition and Results of Operations. For this purpose, any
statements  contained  herein that are not statements of historical  fact may be
deemed to be  forward-looking  statements.  Without limiting the foregoing,  the
words "believes",  "anticipates",  "plans",  "expects",  "estimates" and similar
expressions  are intended to identify  forward-looking  statements.  There are a
number of  important  factors  that could  cause the  results of the  Company to
differ  materially from those indicated herein.  These factors include,  but are
not limited to, those set forth in Item 7 entitled  Management's  Discussion and
Analysis of Financial  Condition and Results of Operations in the Company's Form
10-KSB for the year ended March 31, 1997.

GENERAL

On July 1, 1997,  FirstBank  Northwest  converted  from mutual to stock form and
became a wholly-owned  subsidiary of a newly formed  Delaware  holding  company,
FirstBank Corp. The Company sold 1,983,750  shares of common stock at $10.00 per
share in conjunction with a subscription offering to the Savings Bank's Employee
Stock Ownership Plan (ESOP) and eligible account holders.  The net proceeds were
approximately $18,921,825.  The company used approximately $9,470,000 of the net
proceeds to purchase  all the capital  stock of the Savings  Bank.  In addition,
$1,587,000  was loaned to the ESOP for the  purchase  of  158,700  shares in the
offering.

The Company's principal business is the business of the Savings Bank. Therefore,
the  discussion  in  the  Management's  Discussion  and  Analysis  of  Financial
Conditions  and  Results  of  Operation  relates  to the  Savings  Bank  and its
operations.  During the  quarter  the Bank  opened up a small  retail  branch in
Clarkston, Washington. The Bank now has offices in Idaho and Washington.

During  the  quarter a VISA  credit  card  program  was  started.  FirstBank  is
performing the credit underwriting on the credit cards and retaining the credit.
A Debit Card program will be implemented  during the next quarter. A new 24 hour
banking telephone is being installed and should be available for customer to use
in the next  quarter.  The 24 hour  banking  system lets  customers  examine and
transfer monies between their accounts any time of the day.

FINANCIAL CONDITION AT SEPTEMBER 30, 1997 AND MARCH 31, 1997

Assets  increased  from $137.7  million at March 31,  1997 to $177.9  million at
September 30, 1997.  Cash and cash  equivalents  increased  from $5.3 million at
March  31,  1997  to  $14.7  million  at  September  30,  1997.  Mortgage-backed
securities  available-for-sale  increased from $2.6 million at March 31, 1997 to
$9.0 million at September  30, 1997.  Loans  receivable,  increased  from $113.0
million at March 31, 1997 to $133.1 million at September 30, 1997 as a result of
increased  commercial lending of $9.0 million , consumer lending of $6.0 million
and $4.0 million in residential  real estate lending.  The increases in cash and
cash  equivalents,  mortgage-backed  securities  available-for-sale,  and  loans
receivable were  attributable to the proceeds  received from the company's stock
offering  and from  Federal  Home Loan Bank of  Seattle  (FHLB)  advances  which
increased from $13.9 million at March 31, 1997 to $35.1 million at September 30,
1997.  Accrued interest  receivable  increased $1.0 million at March 31, 1997 to
$1.8  million  at  September  30,  1997 due to a higher  average  asset  base in
securities and loans.  Deposits  increased from $107.6 million at March 31, 1997
to $108.5  million at  September  30, 1997.  Activity  within  deposit  balances
includes a decrease of  approximately  $5.6  million  used to fund  purchases of
stock.  The increase in deposits is primarily due to the Savings Bank benefiting
from funds  deposited  by the  customers  of the local  institutions,  following
larger  bank  mergers,  who  become  frustrated  due to  higher  fees  and  less
personalized service. Accrued expenses and other liabilities decreased from $1.2
million at March 31, 1997 to $1.0  million at September  30,  1997.  The primary
reason for the decrease was timing of investor mortgage loan payoffs.  It is the
policy of the Savings Bank to cease  accruing  interest on loans 90 days or more
past due. Nonaccrual loans decreased from $1.1 million at March 31, 1997 to $1.0
million at September 30, 1997.

RESULTS OF OPERATIONS FOR QUARTER ENDED SEPTEMBER 30, 1997

Net  earnings  increased  from a net loss of $75,000 for the three  months ended
September 30, 1996 to net income  $481,000 for the three months ended  September
30, 1997. The results for the three months ended  September 30, 1996 reflect the
payment of an  industry-wide,  one time special  assessment to recapitalize  the
Savings  Association  Insurance  Fund (SAIF).  The Savings Bank's portion of the
assessment was $584,000.

Net  interest  income  increased  from $1.2  million for the three  months ended
September  30, 1996 to $1.8  million for the three months  ended  September  30,
1997.  Total  interest  income  increased from $2.6 million for the three months
ended  September  30, 1996 to $3.5 million for three months ended  September 30,
1997.  The  increase  in  interest  income  stemmed  from an increase in average
earning assets and higher yields on those assets.  The weighted average yield on


                                                                               7
<PAGE>


the loan  portfolio  was 8.97% as of September  30,  1997,  whereas the weighted
yield average at September 30, 1996 was 8.84%.  Interest  income from investment
securities decreased from $163,000 for the three months ended September 30, 1996
to $112,000  for the three  months ended  September  30,  1997.  The decrease is
primarily due to a decrease in average  balances  outstanding.  Interest  income
from  mortgage-backed  securities  increased  from  $34,000 for the three months
ended  September  30, 1996 to $121,000 for the three months ended  September 30,
1997.  The increase was due  primarily  to the  purchase of  approximately  $6.4
million in  mortgage-backed  securities  available-for-sale  with higher yields.
Interest  expense  increased  from  $1.3  million  for the  three  months  ended
September  30,  1996 to $1.7  million  for the same  time  period  in 1997.  The
increase in interest expense is due primarily to higher average deposit balances
and an increase in FHLB advances.  The weighted average rate on deposits for the
three months ended  September 30, 1997 was 4.26%,  whereas the weighted  average
rate on deposits as of September 30, 1996 was 4.54%.  The weighted  average rate
on FHLB  advances  for the three  months  ended  September  30,  1997 was 7.07%,
whereas the weighted  average rate on FHLB advances as of September 30, 1996 was
6.01%.

A one time increase in income was realized in the quarter  ending  September 30,
1997.  Said increase of $41,000 is attributable to the spread on the money which
was held for the conversion.

Provision for loan losses is based upon  management's  consideration of economic
conditions  which may  affect  the  ability  of  borrowers  to repay the  loans.
Management also reviews  individual loans for which full  collectibility may not
be reasonably assured and considers,  among other matters, the risks inherent in
the Savings  Bank's  portfolio  and the estimated  fair value of the  underlying
collateral.  This evaluation is ongoing and results in variations in the Savings
Bank's provision for loan losses.  As a result of this  evaluation,  the Savings
Bank's  provision  for loan losses  increased  from $28,000 for the three months
ended  September  30, 1996 to $50,000 for the three months ended  September  30,
1997.

Non-interest income decreased from $596,000 for the three months ended September
30, 1996 to $538,000 for the three months ended  September 30, 1997. The primary
reason  was due to a decrease  in gain on sale of loans as loans sold  decreased
from $29.5  million  for the three  months  ended  September  30,  1996 to $25.5
million for the three months ended September 30, 1997.

Non-interest  expense  decreased  from $1.9  million for the three  months ended
September 30, 1996 to $1.5million for the three months ended September 30, 1997.
The decrease is  primarily  due to a charge in 1996 of $584,000 for the one time
expense  for SAIF  premium.  The  decrease  was  offset by  compensation  for an
additional  loan  officer  hired in  Lewiston  from one of the  larger  regional
national banks.

Income  taxes  increased  from a benefit of $58,000 for the three  months  ended
September 30, 1996 to expense of $293,000 for the same time period in 1997.  The
increase was primarily due to a increase in taxable income.


RESULTS OF OPERATIONS FOR SIX MONTHS ENDED SEPTEMBER 30, 1997

Net earnings increased from $141,000 for the six months ended September 30, 1996
to $707,000 for the six months ended September 30, 1997.

Net  interest  income  increased  from $2.4  million  for the six  months  ended
September 30, 1996 to $3.2 million for the six months ended  September 30, 1997.
Total  interest  income  increased  from $5.1  million for the six months  ended
September 30, 1996 to $6.4 million for six months ended  September 30, 1997. The
increase in interest  income stemmed from an increase in average  earning assets
and  higher  yields on those  assets.  The  weighted  average  yield on the loan
portfolio was 8.94% as of September 30, 1997, whereas the weighted yield average
at September  30, 1996 was 8.91%.  Interest  income from  investment  securities
decreased from $364,000 for the six months ended  September 30, 1996 to $184,000
for the six months ended  September 30, 1997. The decrease is primarily due to a
decrease in average balances  outstanding.  Interest income from mortgage-backed
securities increased from $68,000 for the six months ended September 30, 1996 to
$220,000  for the six months  ended  September  30,  1997.  The increase was due
primarily  to the  purchase  of  approximately  $6  million  in  mortgage-backed
securities  available-for-sale  with higher yields.  Interest expense  increased
from $2.7  million for the six months ended  September  30, 1996 to $3.2 million
for the same time  period in 1997.  The  increase  in  interest  expense  is due
primarily to higher average  deposit  balances and an increase in FHLB advances.
The weighted  average rate on deposits  for the six months ended  September  30,
1997 was 4.28%,  whereas the  weighted  average rate on deposits as of September
30, 1996 was 4.59%.

Provision for loan losses is based upon  management's  consideration of economic
conditions  which may  affect  the  ability  of  borrowers  to repay the  loans.
Management also reviews  individual loans for which full  collectibility may not
be reasonably assured and considers,  among other matters, the risks inherent in

                                                                               8
<PAGE>


Bank's provision for loan losses increased from $56,000 for the six months ended
September 30, 1996 to $68,000 for the six months ended September 30, 1997.

Non-interest  income  decreased  from  $1.2  million  for the six  months  ended
September 30, 1996 to $1.0 million for the six months ended  September 30, 1997.
The primary  reason was due to a decrease in gain or sale of loans as loans sold
decreased  from $64.0  million for the six months  ended  September  30, 1996 to
$51.2 million for the six months ended September 30, 1997.

Non-interest  expense  decreased  from $3.3  million  for the six  months  ended
September 30, 1996 to $3.0 million for the six months ended  September 30, 1997.
Despite an  increase  in 1997  compensation  and other  expenses  related to the
addition of personnel  for expanding  loan  products,  last year's  non-interest
expense was higher due to the one time SAIF  charge of  $584,000.  Income  taxes
increased  from $95,000 for the six months ended  September 30, 1996 to $428,000
for the same time period in 1997.  The decrease was  primarily due to a increase
in taxable income.


LIQUIDITY AND CAPITAL RESOURCES

The Savings Bank's  principal  sources of funds are cash receipts from deposits,
loan repayments by borrowers, sale of loans and net income. The Savings Bank has
an agreement with FHLB to provide cash advances,  should the need for additional
funds be required.  Advances  totaled  $35.1  million at September  30, 1997. In
addition,  the  Company had $9.0  million of  securities  available  for sale at
September 30, 1997. The Savings Bank uses its liquidity resources principally to
fund  existing and future loan  commitments,  to fund maturing  certificates  of
deposit and deposit withdrawals,  to invest in other interest-earning assets, to
maintain liquidity and to meet operating expenses. Management believes that loan
repayments  and other  sources of funds will be  adequate  to meet or exceed the
Bank's liquidity needs for the remainder of fiscal 1997.

For  regulatory  purposes,  liquidity is measured as a ratio of cash and certain
investments to withdrawable deposits. The minimum level of liquidity required by
regulation is presently 5%. The Savings Bank's liquidity ratio was approximately
8.52% at September 30, 1997.

Commitments  to originate  adjustable-rate  mortgage loans at September 30, 1997
were approximately $6.6 million.  Commitments to originate  fixed-rate  mortgage
loans at September 30, 1997 were  approximately  $10.3  million.  Commitments to
fund  outstanding  credit lines at September  30, 1997 were  approximately  $7.3
million.   Commitments   for  commercial   loans  at  September  30,  1997  were
approximately $2.1 million.

The Savings  Bank is  required to meet  certain  tangible,  core and  risk-based
capital  requirements.  The following  table presents the Savings Bank's capital
position relative to its regulatory capital requirements at September 30, 1997:
