CORNERSTONE BANCORP, INC. AND SUBSIDIARY
----------------------------------------
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (UNAUDITED)
--------------------------------------------------------
(dollars in thousands)

NOTE A - BASIS OF PRESENTATION

     The accompanying unaudited interim consolidated financial statements
include the accounts of Cornerstone Bancorp, Inc. and Cornerstone Bank (the
"Bank"), collectively the "Company". The interim consolidated financial
statements have been prepared in conformity with generally accepted accounting
principles for interim financial statements and the instructions to Form 10-QSB,
and, accordingly, do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of management, the accompanying unaudited consolidated financial
statements reflect all adjustments necessary, consisting only of normal
recurring accruals, to present fairly the financial position, results of
operations, changes in stockholders' equity and cash flows at the dates and for
the periods presented. In preparing the interim consolidated financial
statements, management is required to make estimates and assumptions that affect
the reported amounts of assets and liabilities as of the date of the statement
of condition and revenues and expenses for the period. Actual results could
differ significantly from those estimates. A material estimate that is
particularly susceptible to near-term change is the allowance for loan losses.
The interim results of operations for the first six months of 2000 are not
necessarily indicative of the results to be expected for the year ending
December 31, 2000.

     While management believes that the disclosures presented are adequate so as
not to make the information misleading, it is suggested that these interim
consolidated financial statements be read in conjunction with the annual
consolidated financial statements and notes included in the Form 10-KSB for the
year ended December 31, 1999.

NOTE B - EARNINGS PER SHARE

     Basic EPS is computed by dividing net income by the weighted average number
of common shares outstanding for the period. Diluted EPS reflects the potential
dilution that would occur if securities or other contracts to issue common stock
were exercised or converted into common stock, or otherwise resulted in the
issuance of common stock that then shared in the earnings of the entity. For the
three and six month periods ended June 30, 2000 and 1999, the number of shares
for diluted EPS exceeded the number of shares for basic EPS due to the dilutive
effect of outstanding stock options computed using the treasury stock method.
For purposes of computing basic EPS, net income applicable to common stock
equaled net income for these periods.

NOTE C - SEGMENT INFORMATION

     Public companies are required to report certain financial information about
significant revenue-producing segments of the business for which sufficient
information is available and utilized by the chief operating decision maker.
Specific information to be reported for individual operating segments includes a
measure of profit and loss, certain revenue and expense items, and total assets.
As a community-oriented financial institution, substantially all of the Bank's
operations involve the delivery of loan and deposit products to customers.
Management makes operating decisions and assesses performance based on an
ongoing review of these banking operations, which constitute the Company's only
operating segment for financial reporting purposes.

FORWARD-LOOKING STATEMENTS

     The statements contained in this report that are not historical are
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended. Examples of such forward-looking statements include, without
limitation, statements by the Company regarding expectations for earnings,
credit quality and other financial and business matters. In addition, when used
in this report, the words "anticipate," "plan," "believe," "estimate," "expect"
and similar expressions as they relate to the Company or its management are
intended to identify forward-looking statements. All forward-looking statements
involve risks and uncertainties. Actual results may differ materially from those
discussed in, or implied by, the forward-looking statements as a result of
certain factors, including but not limited to, competitive pressures on loan and
deposit product pricing, other actions of competitors, changes in economic
conditions, the extent and timing of actions of the Federal Reserve Board,
customer deposit disintermediation, changes in customers' acceptance of the
Company's products and services, and the extent and timing of legislative and
regulatory actions and reforms.

     The forward-looking statements contained in this report speak only as of
the date on which such statements are made. By making any forward-looking
statements, the Company assumes no duty to update them to reflect new, changing
or unanticipated events or circumstances.

FINANCIAL CONDITION

General

     Total assets increased from $139,407 at December 31, 1999 to $153,793 at
June 30, 2000, an increase of $14,386 (or 10%). The increase reflects loan
growth of $13,491 and an increase of $4,027 in cash and cash equivalents,
partially offset by decreases of $2,085 in securities held to maturity and
$1,035 in securities available for sale. The asset growth was funded principally
from an increase of $8,279 in deposits, Federal Home Loan Bank ("FHLB")
borrowings of $5,000 and repurchase agreement borrowings of $1,311. A portion of
this funding ($852) was also used to purchase 74,265 treasury shares under the
Company's program, announced in December 1999, to repurchase up to 100,000
common shares.

Loans

     The net loan portfolio increased from $78,038 at December 31, 1999 to
$91,529 at June 30, 2000, an increase of $13,491 (or 17%). The increase in the
loan portfolio in the first six months of 2000 primarily reflects increases in
non-residential, residential and commercial loans, which were partially offset
by a decrease in construction loans. Non-residential loans increased from
$25,470 at December 31, 1999 to $35,354 at June 30, 2000, an increase of $9,884
(or 39%). Residential loans increased from $35,501 at December 31, 1999 to
$38,634 at June 30, 2000, an increase of $3,133 (or 9%). Commercial loans
increased from $9,604 at December 31, 1999 to $11,342 at June 30, 2000, an
increase of $1,738 (or 18%). Loan originations in the second quarter of 2000
continued to reflect an upswing in loan demand and consequently volume that
began in the third quarter of 1999 for all loan types (except construction
loans). Construction loans decreased from $6,022 at December 31, 1999 to $4,848
at June 30, 2000,

                                      -7-
<PAGE>

a decrease of $1,174 (or 19%)due to the payoff of two construction loans
totaling $1,400 during the six months ended June 30, 2000.

Major classifications of loans at June 30, 2000 and December 31, 1999 were as

Non-performing Loans and the Allowance for Loan Losses

     It is the Bank's policy to manage its loan portfolio to facilitate
recognition of problem loans at an early point. The Bank commences internal
collection efforts once a loan payment is more than 15 days past due. The Bank's
data processing system generates delinquency reports on all of the Bank's loans
weekly and management reviews the loan portfolio on a weekly basis to determine
if past due loans should be placed on non-accrual status. Unless the customer is
working with the Bank toward repayment, once a loan payment is 90 days past due,
the Bank generally initiates appropriate collection action.

The following table sets forth information with respect to non-performing loans
at the dates indicated.

<PAGE>

    The decline in real estate secured loans for which interest payments were
being applied to principal (from $846 at December 31, 1999 to $319 at June 30,
2000) was primarily due to management's decision in the second quarter to return
loans amounting to $471 to accrual status due to the borrowers' continuing
payment performance. The increase in nonaccrual commercial loans of $460
primarily represents loans to one borrower placed on nonaccrual status during
the second quarter of 2000.

    The following table sets forth  changes in the allowance for loan losses for
the periods indicated.

Securities

    Total securities decreased from $43,169 at December 31, 1999 to $40,049 at
June 30, 2000, a decrease of $3,120 (or 7%).  The decrease in the securities
portfolio was primarily due to maturities of securities held to maturity and
sales of securities available for sale which were used to meet short term cash
needs and fund a portion of the loan growth.

  The following table sets forth the amortized cost and estimated fair value of
the securities portfolio at the dates indicated.

</TABLE>

     Total deposits increased from $119,282 at December 31, 1999 to $127,561 at
June 30, 2000, an increase of $8,279 (or 7%).  Demand deposits increased from
$25,177 at December 31, 1999 to $32,013 at June 30, 2000, an increase of
$6,836 (or 27%).  Money market demand and NOW accounts increased from $21,058 at
December 31, 1999 to $25,668 at June 30, 2000, an increase of $4,610 (or 22%).
The increase in demand deposits at June 30, 2000 was attributable to the Bank's
focus on lower cost demand deposits, as well as funding to cover incoming
cashier's checks.  The increase in money market, demand and NOW accounts was
attributable to activity associated with attorney/trustee accounts. These
increases were partially offset by a decrease in regular, club and money market
savings from $28,187 at December 31, 1999 to $26,577 at June 30, 2000, a
decrease of $1,610 (or 6%) as well as a decrease in time deposits from $44,860
at December 31, 1999 to $43,303 at June 30, 2000, a decrease of $1,557 (or 3%).
Approximately $1.5 million of the decrease in time deposits was attributable to
maturities and withdrawals of accounts opened during the last three quarters of
1995 in connection with a promotion. The decrease in regular, club and money
market savings was attributable to normal customer activity. Certificates of
deposit in denominations of $100 or more were $9,820 at December 31, 1999
compared to $10,336 at June 30, 2000, an increase of $516.

Liquidity and Capital Resources

     At June 30, 2000, total short term investments, which are made up of
federal funds sold, available for sale securities and held to maturity
securities maturing in three months or less, totaled $32,517. The liquidity of
the Company is measured by the ratio of net cash, short term investments, and
marketable assets to net deposits and short term liabilities. The liquidity
ratio at June 30, 2000 was 34%, primarily due to the large available for sale
portfolio. The Company's guideline is to maintain a liquidity ratio of 20% or
more.

     Net cash provided by operating activities was $1,012 for the six months
ended June 30, 2000 as compared to $385 for the six months ended June 30, 1999.
Compared to the first half of 1999, cash used in investing activities increased
$2,610 primarily due to increased net disbursements for loan originations in
2000, partially offset by 1999 purchases of held to maturity securities.  The
increase in net cash provided by financing activities of $8,594 primarily
resulted from  higher borrowings and deposit inflows in the current year.  Cash
and cash equivalents increased $4,027 for the six months ended June 30, 2000.

     At June 30, 2000, the Company had outstanding loan commitments under unused
lines of credit approximating $13,654 and outstanding letters of credit
approximating $147.

       At December 31, 1999 and June 30, 2000, the Company's consolidated
leverage capital ratio was 11.1% and 10.7%, respectively.  At December 31, 1999
and June 30, 2000, the Company's consolidated Tier 1 risk-based capital ratio
was 18.4% and 15.4%, respectively.  The Company's consolidated total risk-based
capital ratio at December 31, 1999 and June 30, 2000 was 19.6% and 16.6%,
respectively. These ratios exceeded the stated minimum regulatory requirements.
The lower capital ratios at June 30, 2000 reflect the growth in the loan
portfolio and the stock repurchase program in 2000, as well as an increase in
total risk-weighted caused by a reduction in cash and cash reserves at the
Federal Reserve Bank of New York which were unusually high at the end of 1999
due to year 2000 concerns.  The Bank's

                                      -10-

regulatory capital ratios at June 30, 2000 were substantially the same as these
consolidated ratios, and the Bank was classified as a well-capitalized
institution for regulatory purposes.

RESULTS OF OPERATIONS

Comparative Analysis of Operating Results for the Three Months Ended June 30,
2000 versus June 30, 1999

NET INCOME. Net income was $313 for the three months ended June 30, 1999
compared to $438 for the three months ended June 30, 2000, an increase of $125
(or 40%). Diluted earnings per share were $0.27 for the three months ended June
30, 1999 and $0.40 for the three months ended June 30, 2000 based on weighted
average shares of 1,157,030 and 1,090,725, respectively. The annualized return
on average common stockholders' equity (R.O.E) was 8.29% and 11.30% for the
three months ended June 30, 1999 and June 30, 2000, respectively. The annualized
return on average assets was 0.89% for the three months ended June 30, 1999 and
1.18% for the three months ended June 30, 2000.

     Higher net income for the three months ended June 30, 2000 was principally
due to increased net interest income which was partially offset by increases in
the provision for loan losses and income tax expense.

Net Interest Income.  Net interest income is the difference between the interest
income the Company earns on its loans, securities, and other earning assets, and
the interest cost of deposits and other interest-bearing liabilities necessary
to fund these earning assets. It is the primary component of the Company's
earnings.

    Net interest income was $1,588 for the three months ended June 30, 1999
compared to $1,885 for the three months ended June 30, 2000, an increase of $297
(or 19%). Higher loan volume resulted in increased interest income while the
rolloff of higher priced certificates of deposit resulted in decreased interest
expense on deposits. This decrease was partially offset by interest expense on
FHLB borrowings and an increase in other interest expense. The average yield on
interest-earning assets increased 58 basis points for the three months ended
June 30, 2000 compared to June 30, 1999, while the average rate paid on
interest-bearing liabilities remained unchanged. These changes resulted in a 63
basis point increase in the net interest margin for the three months ended June
30, 2000 compared to June 30, 1999. The higher asset yields reflect increased
loan volume as well as increases in market interest rates. The stable funding
costs reflect the maturity or withdrawal of higher priced deposit accounts,
partially offset by the effect of the increased volume of borrowed funds during
the second quarter of 2000.

Interest Income. Average earning assets for the three months ended June 30, 1999
were $131,125 compared to $137,840 for the three months ended June 30, 2000, an
increase of $6,715 (or 5%). Total interest income, which is a function of the
volume of interest-earning assets and their related rates, was $2,469 for the
three months ended June 30, 1999 and $2,795 for the three months ended June 30,
2000, representing an increase of $326 (or 13%).

     Loans represent the largest component of interest-earning assets. Average
loans outstanding in the three months ended June 30, 1999 were $70,936 compared
to $89,680 during the three months ended June 30, 2000, an increase of $18,744
(or 26%). Interest on loans was $1,632 for the three months ended June 30, 1999
compared to $2,070 for the three months ended June 30, 2000, an increase of $438
(or 27%). The increase in loan income reflects the increase in loan volume for
the three months ended June 30, 2000 compared to June 30, 1999.

                                      -11-
<PAGE>

    Average investments in securities and federal funds sold were $60,189 for
the three months ended June 30, 1999 compared to $48,160 for the three months
ended June 30, 2000, a decrease of $12,029 (or 20%). Related income decreased
from $837 for the three months ended June 30, 1999 to $725 for the three months
ended June 30, 2000, a decrease of $112 (or 13%). Average investments in
securities, not including federal funds, decreased by $4,388 (or 10%) during the
three months ended June 30, 2000, while average federal funds sold decreased by
$7,641 (or 54%). The decrease in income from securities and federal funds sold
was primarily due to the reduced volume in both categories, partially offset by
increasing rates of interest earned on federal funds sold.

Interest Expense. Interest expense was $881 for the three months ended June 30,
1999 compared to $910 for the three months ended June 30, 2000, a 3% increase.
Interest expense is a function of the volume of interest-bearing liabilities and
their related rates. Average interest-bearing liabilities during the three
months ended June 30, 1999 were $99,886 compared to $103,108 during the three
months ended June 30, 2000, an increase of $3,222 (or 3%). Increased interest
expense was primarily due to the increased volume of non-maturity deposits, FHLB
borrowings and repurchase agreements which was partially offset by the declining
volume of time deposits.

Provision for Loan Losses. The periodic provision for loan losses represents the
amount necessary to adjust the allowance for loan losses to management's
estimate of probable credit losses inherent in the existing loan portfolio at
the reporting date. Management's determination of the allowance for loan losses
is based on the results of continuing reviews of individual loans and borrower
relationships, particularly in the commercial and commercial real estate loan
portfolios. A review of the quality of the loan portfolio is conducted
internally by management on a quarterly basis, using a consistently-applied
methodology, and the results are presented to the Board of Directors for
approval. The evaluation covers individual borrowers whose aggregate loans are
greater than $100, as well as all adversely-classified loans. Management also
considers factors such as the borrower's financial condition, historical and
expected ability to make loan payments, and underlying collateral values. The
determination of the allowance for loan losses also considers the level of past
due loans, the Bank's historical loan loss experience, changes in loan portfolio
mix, geographic and borrower concentrations, and current economic conditions.
The provision for loan losses was $5 for the three months ended June 30, 1999
and $102 for the three months ended June 30, 2000, primarily reflecting
continuing loan growth in 2000. As of June 30, 2000, the allowance for loan
losses was $1,800 or 1.93% of gross loans, compared to $1,626 or 2.04% of gross
loans at December 31, 1999.

     At June 30, 2000, the Company had $1,154 of nonperforming loans, including
$831 of nonaccrual loans and $4 of accruing loans greater than 90 days past due.
Loans less than 90 days past due for which interest payments were being applied
to reduce principal balances, were $319 at June 30, 2000.  At December 31, 1999,
the Company had $1,306 of nonperforming loans, including $388 of nonaccrual
loans and $72 of accruing loans greater than 90 days past due.  Loans less than
90 days past due for which interest payments were being applied to reduce
principal balances, were $846 at December 31, 1999.

Non-interest Income.  Non-interest income was $214 for the three months ended
June 30, 1999 compared to $180 for the three months ended June 30, 2000, a
decrease of $34 (or 16%).  During the three months ended June 30, 2000, the Bank
sold one available for sale security at a loss of $14.  The decline in other
non-interest income of $24 (or 23%) during the three months ended June 30, 2000
reflects one-time service charges on loans amounting to $25 which were collected
during the quarter ended June 30, 1999.

Non-interest Expense. Total non-interest expenses were $1,231 for the three
months ended June 30, 1999 and $1,263 for the three months ended June 30, 2000,
a decrease of $32 (or 3%).

</TABLE>

     The increase in salaries and employee benefits was due to the addition of
four employees and associated benefits. In May 1999, the Bank opened its fifth
branch which is located in Norwalk, Connecticut. The increase in occupancy
expense primarily resulted from additional rent and depreciation associated with
the Norwalk branch. The decrease in other non-interest expense categories
primarily relates to organization costs absorbed in 1999 relating to the
establishment of the bank holding company.

     The following table summarizes dollar amounts for each category as a
percentage of total operating income (interest income plus non-interest income),
which increased by $292, (or 11%) in the second quarter of 2000 compared to the
same period in 1999:

Income Taxes. The provision for income taxes increased from $221 for the three
months ended June 30, 1999 to $294 for the three months ended June 30, 2000, an
increase of $73 (or 33%). The increase in income taxes was due to the 33%
increase in pre-tax income.

Comparative Analysis of Operating Results for the Six Months Ended June 30, 2000
versus June 30, 1999

Net Income. Net income was $635 for the six months ended June 30, 1999 compared
to $833 for the six months ended June 30, 2000, an increase of $198 (or 31%).
Diluted earnings per share were $0.54 for the six months ended June 30, 1999 and
$0.75 for the six months ended June 30, 2000 based on weighted average shares of
1,167,550 and 1,108,697, respectively. The annualized return on average common
stockholders' equity (R.O.E) was 8.49% and 11.29% for the six months ended June
30, 1999 and June 30, 2000, respectively. The annualized return on average
assets was 0.92% for the six months ended June 30, 1999 and 1.21% for the six
months ended June 30, 2000.

     Higher net income for the six months ended June 30, 2000 was principally
due to increased net interest income (reflecting an increase in interest income
and a reduction in interest expense) which was partially offset by increases in
the provision for loan losses, non-interest expense and income tax expense.

                                      -13-
<PAGE>

Net Interest Income.  Net interest income was $3,060 for the six months ended
June 30, 1999 compared to $3,644 for the six months ended June 30, 2000, an
increase of $584 (or 19%).  Higher loan volume resulted in increased interest
income while the rolloff of higher priced certificates of deposit resulted in
decreased interest expense on deposits.  This reduction in interest expense was
partially offset by interest expense on FHLB borrowings and an increase in other
interest expense.  The average yield on interest-earning assets increased 58
basis points for the six months ended June 30, 2000 compared to June 30, 1999,
while the average rate paid on interest-bearing liabilities decreased 11 basis
points.  These changes resulted in a 72 basis point increase in the net interest
margin for the six months ended June 30, 2000 compared to June 30, 1999.  The
higher asset yields reflect a shift in asset mix to higher yielding loans, as
well as recent increases in market interest rates.  The lower average funding
cost reflects the maturity or withdrawal of higher priced deposit accounts,
partially offset by the effect of  FHLB borrowings in the six months ended June
30, 2000.

Interest Income.  Average earning assets for the six months ended June 30, 1999
were $130,262 compared to $134,680 for the six months ended June 30, 2000, an
increase of $4,418 (or 3%).  Total interest income, which is a function of the
volume of interest-earning assets and their related rates, was $4,838 for the
six months ended June 30, 1999 and $5,387 for the six months ended June 30,
2000, representing an increase of  $549 (or 11%).

     Loans represent the largest component of interest-earning assets.  Average
loans outstanding in the six months ended June 30, 1999 were $70,646 compared to
$86,297 during the six months  ended June 30, 2000, an increase of $15,651 (or
22%).  Interest on loans was $3,170 for the six months ended June 30, 1999
compared to $3,942 for the six months ended June 30, 2000, an increase of $772
(or 24%).  The increase in loan income primarily reflects the increase in loan
volume for the six months ended June 30, 2000 compared to June 30, 1999.

     Average investments in securities and federal funds sold were $59,616 for
the six months ended June 30, 1999 compared to $48,383 for the six months ended
June 30, 2000, a decrease of $11,233 (or 19%).  Related income decreased from
$1,668 for the six months ended June 30, 1999 to $1,445 for the six months ended
June 30, 2000, a decrease of $223 (or 13%).  Average investments in securities,
not including federal funds sold, decreased by $714 (or 2%) during the six
months ended June 30, 2000 while average federal funds sold decreased by $10,519
(or 64%).  The decrease in income from securities and federal funds sold was
primarily due to the reduced volume in both categories which was partially
offset by increasing rates of interest earned on federal funds sold.

Interest Expense.  Interest expense was $1,778 for the six months ended June 30,
1999 compared to $1,743 for the six months ended June 30, 2000, a 2% decrease.
Interest expense is a function of the volume of interest-bearing liabilities and
their related rates.  Average interest-bearing liabilities during the six months
ended June 30, 1999 were $99,209 compared to $100,478 during the six months
ended June 30, 2000, an increase of $1,269 (or 1%).  The increase in average
interest-bearing liabilities was primarily due to the increase in the volume of
non-maturity deposit accounts, FHLB borrowings, and repurchase agreements
partially offset by a decrease in average time deposits.

Provision for Loan Losses.  The provision for loan losses was ($12) for the six
months ended June 30, 1999 and $143 for the six months ended June 30, 2000,
primarily reflecting the continuing loan growth in 2000.  As of June 30, 2000,
the allowance for loan losses was $1,800 or 1.93% of gross loans, compared to
$1,626 or 2.04% of gross loans at December 31, 1999.

Non-interest Income.  Non-interest income was $386 for the six months ended June
30, 1999 compared to $352 for the six months ended June 30, 2000, a decline of
$34 (or 9%).  During the six months ended

<PAGE>

June 30, 2000, the Bank sold one available for sale security at a loss of $14.
The decline in other non-interest income of $26 (or 16%) during the six months
ended June 30, 2000, reflects one-time service charges on loans amounting to $25
which were collected during the quarter ended June 30, 1999.

Non-interest Expense.  Total non-interest expenses were $2,377 for the six
months ended June 30, 1999 and $2,457 for the six months ended June 30, 2000, an
increase of $80 (or 3%).

     A table summarizing the dollar amounts for each category, and the dollar
and percent changes, is as follows:

     The increase in salaries and employee benefits resulted from the addition
of four employees, salary increases and increased cost of benefits. The increase
in occupancy expense primarily resulted from additional rent and depreciation
associated with the Norwalk branch opened in May 1999. The decrease in other
non-interest expense primarily relates to organization costs absorbed in 1999
relating to the establishment of the bank holding company.

     The following table summarizes dollar amounts for each category as a
percentage of total operating income (interest income plus non-interest income),
which increased by $515, (or 10%) in the first six months of 2000 compared to
the same period in 1999:

Income Taxes. The provision for income taxes increased from $446 for the six
months ended June 30, 1999 to $563 for the six months ended June 30, 2000, an
increase of $117 (or 26%). The increase in income taxes was primarily due to the
29% increase in pre-tax income.

YEAR 2000

     The operating systems of the Company have been performing properly since

operations.  The Company has had dialogue with its loan customers concerning
their Year 2000 preparedness and has incorporated the consideration of Year 2000
readiness into its loan review and credit underwriting processes.  The Company
is not currently aware of any Year 2000 issues that have adversely affected its
loan customers or the third parties relied upon by the Company for its daily
transaction processing and other technology needs. Management
