                              OLD NORTH STATE BANK
================================================================================

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

NOTE 1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

Old North State Bank (the Bank) was organized and incorporated under the laws
of the State of North Carolina on June 30, 1989.  The Bank commenced operations
on August 14, 1989, and currently serves the counties of Forsyth and Stokes,
and the city of Winston-Salem, North Carolina, through seven banking offices.
As a state chartered, Federal Reserve member bank, the Bank is subject to
regulation by the State of North Carolina Banking Commission and the Federal
Reserve.  Old North State Bank Investments, Inc. is a wholly-owned subsidiary
of the Bank which sells mutual funds and annuities.

The accounting and reporting policies of the Bank and its subsidiary follow
generally accepted accounting principles and general practices within the
financial services industry.  Following is a summary of the more significant
policies.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Bank and it
subsidiary.  All significant, intercompany transactions and balances have been
eliminated in consolidation.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Material estimates that are particularly susceptible to significant change
relate to the determination of the allowance for loan losses and the valuation
of real estate acquired in connection with foreclosures or in satisfaction of
loans.  In connection with the determination of the allowances for loan and
foreclosed real estate losses, management obtains independent appraisals for
significant properties.

Substantially all of the Bank's loan portfolio consists of loans in its market
area.  Accordingly, the ultimate collectibility of a substantial portion of the
Bank's loan portfolio and the recovery of a substantial portion of the carrying
amount of foreclosed real estate are susceptible to changes in local market
conditions.  The regional economy is diverse with the primary employers being
health care, manufacturing and financial services.

While management uses available information to recognize loan and foreclosed
real estate losses, future additions to the allowances may be necessary based
on changes in local economic conditions.  In addition, regulatory agencies, as
a part of their routine examination process, periodically review the Bank's
allowances for loan and foreclosed real estate losses.  Such agencies may
require the Bank to recognize additions to the allowances based on their
judgments about information available to them at the time of their
examinations.  Because of these factors, it is reasonably possible that the
allowances for loan and foreclosed real estate losses may change materially in
the near term.

CASH AND CASH EQUIVALENTS

For the purposes of presentation in the statement of cash flows, cash and cash
equivalents are defined as those amounts included in cash and due from banks
(including items in process of clearing).

TRADING SECURITIES

The Bank does not hold securities for short-term resale and therefore does not
maintain a trading securities portfolio.
    

<PAGE>   9


SECURITIES HELD TO MATURITY

Bonds, notes, and debentures for which the Bank has the positive intent and
ability to hold to maturity are reported at cost, adjusted for premiums and
discounts that are recognized in interest income using the interest method over
the period to maturity or to call dates.
<PAGE>   10
================================================================================

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------


NOTE 1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

SECURITIES AVAILABLE FOR SALE

Available-for-sale securities are reported at fair value and consist of bonds,
notes, debentures, and certain equity securities not classified as trading
securities or as held-to-maturity securities.

Unrealized holding gains and losses, net of tax, on available-for-sale
securities are reported as a net amount in a separate component of
stockholders' equity.  Realized gains and losses on the sale of
available-for-sale securities are determined using the specific-identification
method.  Premiums and discounts are recognized in interest income using the
interest method over the period to maturity or to call dates.

Declines in the fair value of individual held-to-maturity and
available-for-sale securities below cost that are other than temporary are
reflected as write-downs of the individual securities to fair value.  Related
write-downs are included in earnings as realized losses.

LOANS RECEIVABLE AND ALLOWANCE FOR LOAN LOSSES

Loans receivable that management has the intent and ability to hold for the
foreseeable future or until maturity or pay-off are reported at their
outstanding principal amount adjusted for any charge-offs, the allowance for
loan losses, and any deferred fees or costs on originated loans and unamortized
premiums or discounts on purchased loans.

Loan origination fees and certain direct origination costs are capitalized and
recognized as an adjustment of the yield of the related loan.  Discounts and
premiums on any purchased residential real estate loans are amortized to income
using the interest method over the remaining period to contractual maturity,
adjusted for anticipated prepayments. Discounts and premiums on any purchased
consumer loans are recognized over the expected lives of the loans using
methods that approximate the interest method.

Interest is accrued and credited to income based on the principal amount
outstanding.  The accrual of interest on impaired loans is discontinued when,
in management's opinion, the borrower may be unable to meet payments as they
become due.  When interest accrual is discontinued, all unpaid accrued interest
is reversed.  Interest income is subsequently recognized only to the extent
cash payments are received.

The allowance for loan losses is increased by charges to income and decreased
by charge-offs, net of recoveries.  Management's periodic evaluation of the
adequacy of the allowance is based on the Bank's past loan loss experience,
known and inherent risks in the portfolio, adverse situations that may affect
the borrower's ability to repay, the estimated value of any underlying
collateral, and current economic conditions.

PROPERTY AND EQUIPMENT

Land is carried at cost.  Bank premises, furniture and equipment, and leasehold
improvements are carried at cost, less accumulated depreciation and
amortization computed principally by the straight-line method over the
following estimated useful lives:

<TABLE>
                                                   Years
                                                   -----
                       <S>                         <C>
                       Buildings and improvements  10-40
                       Furniture and equipment      3-20
</TABLE>


FORECLOSED PROPERTIES

Real estate properties acquired through, or in lieu of, loan foreclosure are to
be sold and are initially recorded at fair value less anticipated cost to sell
at the date of foreclosure establishing a new cost basis.  After foreclosure,
valuations are periodically performed by management and the real estate is
carried at the lower of carrying amount or fair value less cost to sell.
Revenue and expenses from operations and changes in the valuation allowance are
included in loss on foreclosed real estate.  The historical average holding
period for such properties is less than 12 months.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------



NOTE 1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

STOCK-BASED COMPENSATION

The Company accounts for its stock-based compensation plans using the
accounting prescribed by Accounting Principles Board Opinion No. 25, Accounting
for Stock Issued to Employees.  The Company is not required to adopt the fair
value based recognition provisions prescribed under SFAS No. 123, Accounting
for Stock-Based Compensation (issued in October 1995), but complies with the
disclosure requirements set forth in the Statement, which include disclosing
proforma net income as if the fair value method of accounting had been applied.

INCOME TAXES

Provision for income taxes is based on amounts reported in the statements of
income (after exclusion of non-taxable income such as interest on state and
municipal securities) and consists of taxes currently due plus deferred taxes
on temporary differences in the recognition of income and expense for tax and
financial statement purposes.  Deferred tax assets and liabilities are included
in the financial statements at currently enacted income tax rates applicable to
the period in which the deferred tax assets or liabilities are expected to be
realized or settled.  As changes in tax laws or rates enacted, deferred tax
assets and liabilities are adjusted through the provision for income taxes.

Deferred income tax liability relating to unrealized appreciation (or the
deferred tax asset in the case of unrealized depreciation) on investment
securities available for sale is recorded in other liabilities (assets).  Such
unrealized appreciation or depreciation is recorded as an adjustment to equity
in the financial statements and not included in income determination until
realized.  Accordingly, the resulting deferred income tax liability or asset is
also recorded as an adjustment to equity.

EARNINGS PER COMMON SHARE

Net income per share is computed based on the weighted average number of shares
outstanding during the period, after giving retroactive effect to stock splits
and dividends.

FINANCIAL INSTRUMENTS

Any derivative financial instruments held or issued by the Bank are held or
issued for purposes other than trading.

In the ordinary course of business the Bank has entered into off-balance-sheet
financial instruments consisting of commitments to extend credit and commercial
and standby letters of credit.  Such financial instruments are recorded in the
financial statements when they are funded or related fees are incurred or
received.

The Bank does not utilize interest-rate exchange agreements or interest-rate
futures contracts.

FAIR VALUE OF FINANCIAL INSTRUMENTS

Statement of Financial Accounting Standards No. 107, Disclosures about Fair
Value of Financial Instruments, requires disclosure of fair value information
about financial instruments, whether or not recognized in the balance sheet.
In cases where quoted market prices are not available, fair values are based on
estimates using present value or other valuation techniques.  Those techniques
are significantly affected by the assumptions used, including the discount rate
and estimates of future cash flows.  In that regard, the derived fair value
estimates cannot be substantiated by comparison to independent markets and, in
many cases, could not be realized in immediate settlement of the instruments.
Statement No. 107 excludes certain financial instruments and all nonfinancial
instruments from its disclosure requirements.  Accordingly, the aggregate fair
value amounts presented do not represent the underlying value of the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------


NOTE 1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

FAIR VALUE OF FINANCIAL INSTRUMENTS, CONTINUED

The following methods and assumptions were used by the Company in estimating
its fair value disclosures for financial instruments:

Cash and cash equivalents:  The carrying amounts reported in the balance sheet
for cash and cash equivalents approximate their fair values.

Interest-bearing deposits with banks:  Fair values for time deposits are
estimated using a discounted cash flow analysis that applies interest rates
currently being offered on certificates to a schedule of aggregated contractual
maturities on such time deposits.

Available-for-sale and held-to-maturity securities:  Fair values for
securities, excluding restricted equity securities, are based on quoted market
prices, where available.  If quoted market prices are not available, fair
values are based on quoted market prices of comparable instruments.  The
carrying values of restricted equity securities approximate fair values.

Loans receivable:  For variable-rate loans that reprice frequently and with no
significant change in credit risk, fair values are based on carrying amounts.
The fair values for other loans are estimated using discounted cash flow
analysis, based on interest rates currently being offered for loans with
similar terms to borrowers of similar credit quality.  Loan fair value
estimates include judgments regarding future expected loss experience and risk
characteristics.  Fair value for impaired loans are estimated using discounted
cash flow analysis or underlying collateral values, where applicable.  The
carrying amount of accrued interest receivable approximates its fair value.

Deposit liabilities:  The fair values disclosed for demand and savings deposits
are, by definition, equal to the amount payable on demand at the reporting
date.  The fair values for certificates of deposit are estimated using a
discounted cash flow calculation that applies interest rates currently being
offered on certificates to a schedule of aggregated contractual maturities on
such time deposits.  The carrying amount of accrued interest payable
approximates fair value.

Short-term debt:  The carrying amounts of short-term debt approximate their
fair values.

Other liabilities:  For fixed-rate loan commitments, fair value considers the
difference between current levels of interest rates and the committed rates.
The carrying amounts of other liabilities approximates fair value.

RECLASSIFICATION

Certain reclassifications have been made to the prior years' financial
statements to place them on a comparable basis with the current year.  Net
income and stockholders' equity previously reported were not affected by these
reclassifications.

NOTE 2.  BUSINESS COMBINATION

On December 28, 1995, Old North State Bank acquired Piedmont BancShares
Corporation and its consolidated subsidiary, Enterprise Bank and Trust Company,
in exchange for 828,320 shares of Old North State Bank common stock valued at
$5,582,877.  In conjunction with the acquisition, Piedmont BancShares
Corporation and Enterprise Bank and Trust Company were merged with and into Old
North State Bank.  Enterprise Financial Service Corporation, formerly a
wholly-owned subsidiary of Enterprise Bank and Trust Company, was renamed Old
North State Investments, Inc. and continues as a wholly-owned subsidiary of Old
North State Bank.

results of operations attributable to the acquired companies are included in
the consolidated financial statements only from the date of acquisition.  The
excess of purchase price over fair value of net tangible and identified
intangible assets acquired will be amortized on the straight-line basis over 15
years.  The acquisition is summarized as follows:

maturities in mortgage-backed securities because the mortgages underlying the

NOTE 11.  COMMON STOCK

OPTIONS AND WARRANTS

The Bank maintains a qualified incentive stock option plan which originally
reserved up to 67,624 shares for purchase by eligible employees.  Options are
granted under the plan which are exercisable at $5.45 per share or the fair
market value of the Bank's common stock at the date of grant, whichever is
higher.  Options generally vest at 20% per year and expire ten years from the
date of grant (from April 2000 through March 2004), except that expiration and
vesting may occur earlier as a result of death, disability, termination or
certain changes in control of the Bank.  At December 31, 1996, no additional
options are available for grant under the plan.

The Bank also has common stock options outstanding at December 31, 1996 and
1995, issued under a non-qualified employee stock option plan of a company
acquired by the Bank.  Options outstanding pursuant to this arrangement are
fully vested, exercisable at $9.09 per share and expire between July 1999 and
September 2001.  At December 31, 1996, there were 66,098 of these options
outstanding.

At December 31, 1996 and 1995, the Bank had warrants outstanding to purchase
40,342 shares of its common stock.  These warrants were issued to organizers
and founders of a company acquired by the Bank, are immediately exercisable at
$9.09 per share and expire on April 11, 2000.

The Bank maintained a nonqualified stock option plan which reserved up to
33,509 shares (before 1994 stock dividend and 1995 split) for purchase by
directors.  During 1994 options to purchase 33,502 shares (all that were
granted under the plan) were exercised at $11 per share.

NOTE 12.  EMPLOYEE BENEFIT PLANS

The Bank has adopted a profit sharing plan pursuant to Section 401(k) of the
Internal Revenue Code.  The plan covers substantially all employees who have
completed one year of service.  Participants may contribute a percentage of
compensation, subject to a maximum allowed under the Code.  In addition, the
Bank may make additional contributions at the discretion of the Board of
Directors.  The Bank contribution was approximately $13,100 for 1996.  There
was no expense to the Bank relating to this plan for 1995 or 1994, as the plan
was not adopted until December 28, 1995.

NOTE 13.  INCOME TAXES, CONTINUED

OPERATING LOSS AND CARRYFORWARDS

At December 31, 1996, the Bank had federal net operating loss carryforwards for
income tax purposes of approximately $737,900 which will expire from 2005
through 2008 if not previously utilized.  State net economic loss
carryforwards, which expire in 1997 and 1998, amount to approximately $549,000
at December 31, 1996.  The deferred tax benefit resulting from state net
economic loss carryforwards has been offset in full by a valuation allowance.

NOTE 14.  COMMITMENTS AND CONTINGENCIES

LITIGATION

In the normal course of business the Bank is involved in various legal
proceedings.  After consultation with legal counsel, management believes that
any liability resulting from such proceedings will not be material to the
consolidated financial statements.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK

The Bank is party to financial instruments with off-balance-sheet risk in the
normal course of business to meet the financing needs of its customers.  These
financial instruments include commitments to extend credit and standby letters
of credit.  These instruments involve, to varying degrees, credit risk in
excess of the amount recognized in the consolidated balance sheets.

The Bank's exposure to credit loss in the event of nonperformance by the other
party to the financial instrument for commitments to extend credit and standby
letters of credit is represented by the contractual amount of those
instruments.  The Bank uses the same credit policies in making commitments and
conditional obligations as for on-balance-sheet instruments.  A summary of the
Bank's commitments at December 31, 1996 and 1995 is as follows:

Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee.  Since many of the commitments are expected
to expire without being drawn upon, the total commitment amounts do not
necessarily represent future cash requirements.  The Bank evaluates each
customer's creditworthiness on a case-by-case basis.  The amount of collateral
obtained, if deemed necessary by the Bank upon extension of credit, is based on
management's credit evaluation of the party.  Collateral held varies, but may
include accounts receivable, inventory, property and equipment, residential
real estate and income-producing commercial properties.

Standby letters of credit are conditional commitments issued by the Bank to
guarantee the performance of a customer to a third party.  Those guarantees are
primarily issued to support public and private borrowing arrangements.  The
credit risk involved in issuing letters of credit is essentially the same as
that involved in extending loan facilities to customers. Collateral held varies
as specified above and is required in instances which the Bank deems necessary.

NOTE 14.  COMMITMENTS AND CONTINGENCIES, CONTINUED

CONCENTRATIONS OF CREDIT RISK

Substantially all of the Bank's loans, commitments to extend credit, and
standby letters of credit have been granted to customers in the Bank's market
area and such customers are generally depositors of the Bank.  Investments in
state and municipal securities involve governmental entities within and outside
the Bank's market area.  The concentrations of credit by type of loan are set
forth in Note 5.  The distribution of commitments to extend credit approximates
the distribution of loans outstanding.  Standby letters of credit were granted
primarily to commercial borrowers.  The Bank's primary focus is toward consumer
and small business transactions, and accordingly, it does not have a
significant number of credits to any single borrower or group of related
borrowers in excess of $1,000,000.

The Bank has cash and cash equivalents on deposit with financial institutions
which exceed federally-insured limits.

OTHER COMMITMENTS

The Bank has entered into employment agreements with certain of its key
officers covering duties, salary, benefits, stock options, provisions for
termination and Bank obligations in the event of merger or acquisition.

NOTE 15.  REGULATORY RESTRICTIONS

DIVIDENDS

The Bank, as a North Carolina banking corporation, may pay dividends only out
of undivided profits (retained earnings) as determined pursuant to North
Carolina General Statutes Section 53-87.  However, regulatory authorities may
limit payment of dividends by any bank when it is determined that such a
limitation is in the public interest and is necessary to ensure financial
soundness of the Bank.

CAPITAL REQUIREMENTS

The Bank is subject to various regulatory capital requirements administered by
federal banking agencies.  Failure to meet minimum capital requirements can
initiate certain mandatory (and possibly additional discretionary) actions by
regulators that, if undertaken, could have a direct material effect on the
Company's consolidated financial statements.  Under capital adequacy guidelines
and the regulatory framework for prompt corrective action, the Bank must meet
specific capital guidelines that involve quantitative measures of the Bank's
assets, liabilities, and certain off-balance-sheet items as calculated under
regulatory accounting practices.  The Bank's capital amounts and classification
are also subject to qualitative judgments by the regulators about components,
risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier I capital to risk-weighted assets, and of Tier I
capital to average assets, as all those terms are defined in the regulations.
Management believes, as of December 31, 1996, that the Bank meets all capital
adequacy requirements to which it is subject.

As of December 31, 1996, the most recent notification from the Federal Reserve
categorized the Bank as well capitalized under the regulatory framework for
prompt corrective action.  To be categorized as well capitalized the Bank must
maintain minimum total risk-based, Tier I risk-based, and Tier I leverage
ratios as set forth in the table.  There are no conditions or events since that
notification that management believes have changed the institution's category.

NOTE 16.  TRANSACTIONS WITH RELATED PARTIES

The Bank has entered into transactions with its directors, significant
shareholders and their affiliates (related parties). Such transactions were
made in the ordinary course of business on substantially the same terms and
conditions, including interest rates and collateral, as those prevailing at the
same time for comparable transactions with other customers, and did not, in the
opinion of management, involve more than normal credit risk or present other
unfavorable features.  Aggregate transactions involving the purchase of goods
and services from related parties in 1996 amounted to approximately $32,230.

Aggregate 1996 and 1995 loan transactions with related parties were as follows:

NOTE 18.  PENDING AFFILIATION

On March 14, 1997, the Bank entered an agreement to affiliate with LSB
Bancshares, Inc. through an arrangement whereby Old North State Bank would be
merged into Lexington State Bank, a subsidiary of LSB Bancshares, Inc.
Completion of the transaction is subject to a number of conditions, including
approval by the shareholders of Old North State Bank and appropriate regulatory
authorities.

NOTE 19.  LITIGATION

On March 11, 1997, the Bank filed a lawsuit in Forsyth County against two
individuals and a related business to collect the balance of amounts paid by
the Bank (approximately $94,000) to a supplier of the business for purchases
made by the business.

On May 9, 1997, the defendants filed an answer to the lawsuit and included
counterclaims against the Bank on the basis of allegations that the Bank 
(i) unlawfully converted assets of the defendants by placing an administrative
freeze on the defendants' accounts with the Bank (amounting to approximately
$67,000) and (ii) engaged in unfair and deceptive trade practices. The
counterclaims seek compensatory damages in excess of $10,000 and an award of
punitive damages or, in the alternative, that the compensatory damages be
trebled.

The management of Old North State Bank denies the validity of these
counterclaims and intends to vigorously defend these matters in addition to
aggressively pursuing its own claims against the defendants. However, the
litigation is in too early a stage to determine the outcome of this
contingency.

                         INDEPENDENT AUDITOR'S REPORT


Board of Directors and Stockholders
Old North State Bank
Winston-Salem, North Carolina

We have audited the consolidated balance sheets of Old North State Bank and
subsidiary as of December 31, 1996 and 1995, and the related consolidated
statements of income, changes in stockholders' equity and cash flows for each 
of the three years in the period ended December 31, 1996. These consolidated
financial statements are the responsibility of the Bank's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting amounts and disclosures in the financial statements. An audit also
includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Old North State
Bank and subsidiary at December 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

                              OLD NORTH STATE BANK
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. BASIS OF PRESENTATION - The accompanying unaudited financial statements
were prepared in accordance with instructions for Form 10-QSB and therefore, do
not include all disclosures required by generally accepted accounting principals
for a complete presentation of financial statements. In the opinion of
management, the financial statements contain all adjustments necessary to
present fairly the financial condition of Old North State Bank as of June 30,
1997 and December 31, 1996, the results of operations for the six months and
three months ended June 30, 1997 and 1996, and its cash flows for the six months
ended June 30, 1997 and 1996. The results of operations for the six months ended
June 30, 1997 are not necessarily indicative of the results expected for the
full year.

Old North State Bank is located in Winston-Salem, North Carolina. Old North
State Investments, Inc. (a wholly-owned subsidiary of the Bank) sells mutual
funds and annuities. The accounting policies as set forth below are those
followed by the Bank in addition to the accounting policies as set forth in Note
1 of Old North State's annual financial statements previously furnished in
connection with the registration of filing to become a member of the Federal
Reserve Bank.

PRESENTATION OF CASH FLOWS: For purposes of reporting cash flows, cash and due
from banks includes cash and amounts due from depository institutions (including
cash items in process of clearing). Overnight interest-bearing deposits, and
federal funds sold are shown separately. Cash flows from demand deposits, NOW
accounts and savings accounts are reported net since their original maturities
are less than three months. Loans and time deposits are reported net per FASB
statement no. 104. Federal Funds purchased are shown separately.

INVESTMENTS SECURITIES: Investment securities classified as held to maturity are
those debt securities that the Bank has the ability and intent to hold to
maturity. Accordingly, these securities are carried at cost adjusted for
amortization of premium and accretion of discount, computed by the
interest-method over their contractual lives.

Investments classified as available for sale are intended to be held for
indefinite periods of time and include those securities that management may
employ as part of asset/liability strategy or that may be sold in response to
changes in interest rates, prepayments, regulatory capital requirements or
similar factors. These securities are carried at the lower of amortized cost or
market value. Gains and losses on the sales of such securities are determined by
the specific-identification method.

LOANS: Loans are stated at the amount of unpaid principal, reduced by unearned
discount and fees, and an allowance for loan losses.

The allowance for loan losses is maintained at a level considered adequate to
provide for losses that can be reasonably anticipated. The allowance is
increased by provisions charged to operating expense and reduced by net
charge-offs. The Bank makes continuous credit reviews of the loan portfolio and
considers current economic conditions, historical loan loss experience, review
of specific problem loans and other factors in determining the adequacy of the
allowance balance.

Activity in the allowance for loan losses for the six months ended June 30, 1997
and June 30, 1996 follows:

Interest on all loans is accrued daily on the outstanding balance. Accrual of
interest is discontinued on a loan when management believes, after considering
collection efforts and other factors, that the borrower's financial condition is
such that collection of interest is doubtful.

NOTE 2. EARNINGS PER SHARE - Earnings per share for the six months ended June
30, 1997 and 1996, were calculated by dividing net income by the weighted
average number of shares outstanding during the period.

NOTE 3. BALANCE SHEETS - The Balance Sheet at December 31, 1996, has been taken
from the audited financial statements at that date.

NOTE 4. RECLASSIFICATIONS - For comparative purposes, there may be certain
amounts in the 1996 consolidated financial statements which have been
reclassified to conform with the classifications used in 1997. Such
reclassifications have no effect on net income or stockholders' equity as
previously reported.

                    PRO FORMA CONDENSED FINANCIAL INFORMATION

       The following Pro Forma Condensed Financial Information and explanatory
notes are presented to show the impact of the Merger on LSB's historical
financial position and results of operations. The Merger is reflected in the Pro
Forma Condensed Financial Information under the pooling-of-interests method of
accounting.

       The Pro Forma Condensed Balance Sheet presented assumes that the Merger
was consummated on December 31, 1996, and the Pro Forma Condensed Income
Statements assume that the Merger was consummated at the beginning of each
period presented.

       ONSB acquired Piedmont BancShares Corporation and its consolidated
subsidiary, Enterprise Bank and Trust Company, in the fourth quarter of 1995.
The acquisition was accounted for under the purchase method of accounting, and,
accordingly, the consolidated financial statements of LSB reflected in the
following pro forma condensed financial information include the results of
operations of the acquired companies since the date of acquisition.

       The pro forma earnings are not necessarily indicative of the results of
operations had the Merger occurred at the beginning of the periods presented,
nor are they necessarily indicative of the results of future operations.

               NOTES TO PRO FORMA CONDENSED FINANCIAL INFORMATION


   
Note 1.  Certain material, nonrecurring adjustments of approximately 
         $1.5 million (pre-tax) will be recorded in conjunction with the Merger.
         These adjustments include amounts to effect the settlement of
         obligations under existing employment contracts and amounts associated
         with the conversion of ONSB branches. It is estimated that
         approximately $840 thousand of the expenses will be directly related to
         effecting the Merger and therefore will not be deductible for income
         tax purposes. The impact of these adjustments has been reflected in the
         Pro Forma Condensed Balance Sheets as of June 30, 1997, and December
         31, 1996, respectively.

Note 2.  Based on an Exchange Rate of 0.948 for the conversion of ONSB Stock
         into LSB Stock. At June 30, 1997, and December 31, 1996, ONSB had
         1,582,678 and 1,580,978 shares of stock outstanding, respectively.

Note 3.  No pro forma adjustments relating to the Merger are reflected in the
         Pro Forma Condensed Income Statements.

Note 4.  ONSB's weighted average shares outstanding at December 31, 1995 are
         based on 750,659 average shares outstanding adjusted for a 1.922 for
         one stock split paid January 1, 1995 and the acquisition of Piedmont
         BancShares Corporation in exchange for 828,320 shares of ONSB Stock.

Note 5.  ONSB's weighted average shares outstanding at December 31, 1996 are
         based on 1,576,623 average shares outstanding adjusted for the exercise
         of stock options of 8,807 shares.

                 AGREEMENT AND PLAN OF REORGANIZATION AND MERGER


                  THIS AGREEMENT AND PLAN OF REORGANIZATION AND MERGER (this
"Agreement") is made and entered into as of March 14, 1997, by and among LSB
BANCSHARES, INC. ("LSB"), a North Carolina corporation, having its principal
office located in Lexington, North Carolina; LEXINGTON STATE BANK ("LSB Bank"),
a North Carolina chartered bank and a wholly-owned subsidiary of LSB, having its
principal office located in Lexington, North Carolina; and OLD NORTH STATE BANK
("ONSB"), a North Carolina chartered bank having its principal office located in
Winston-Salem, North Carolina.

                                    PREAMBLE

                  The respective Boards of Directors of ONSB and LSB are of the
opinion that the transactions described herein are in the best interests of the
parties and their respective shareholders. This Agreement provides for the
acquisition of ONSB by LSB pursuant to the merger of ONSB with and into LSB
Bank. At the effective time of such merger, the outstanding shares of the
capital stock of ONSB shall be converted into the right to receive shares of the
common stock of LSB (except as provided herein). As a result, shareholders of
ONSB shall become shareholders of LSB. The transactions described in this
Agreement are subject to the approvals of the shareholders of ONSB and LSB, the
Federal Deposit Insurance Corporation, the North Carolina State Banking
Commission, and the satisfaction of certain other conditions described in this
Agreement. It is the intention of the parties to this Agreement that the merger
(i) for federal income tax purposes shall qualify as a "reorganization" within
the meaning of Section 368(a) of the Internal Revenue Code, and (ii) for
accounting purposes shall qualify for treatment as a "pooling of interests"
consistent with GAAP and the rules and regulations of the SEC.

         As a condition and inducement to LSB's willingness to enter into this
Agreement, certain of ONSB's directors and executive officers will execute and
deliver to LSB, on the date hereof, a Support Agreement (a "Support Agreement"),
in substantially the form of Exhibit 3 to this Agreement.

         As an inducement to LSB's willingness to consummate the transactions
contemplated by this Agreement, ONSB and LSB have entered into a certain Option
Agreement dated as of January 20, 1997 (the "Option Agreement"), pursuant to
which ONSB has granted to LSB an option to purchase shares of common stock of
ONSB in accordance with the terms of such Option Agreement.

                  Certain terms used in this Agreement are defined in Section
11.1 hereof.

                  NOW, THEREFORE, in consideration of the premises and the
mutual warranties, representations, covenants and agreements set forth herein,
and other good and

valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties, intending to be legally bound, agree as follows:


                                    ARTICLE 1
                        TRANSACTIONS AND TERMS OF MERGER

                  1.1 MERGER. Subject to the terms and conditions of this
Agreement and the Plan of Merger, at the Effective Time, ONSB shall be merged
with and into LSB Bank, pursuant to Section 53-12 of Chapter 53 of the General
Statutes of North Carolina and in accordance with the provisions of Sections
53-13 and 53-17 of Chapter 53 and Section 55-11- 06 of Chapter 55 of the General
Statutes of North Carolina. LSB Bank shall be the Surviving Bank resulting from
the Merger and shall continue to be operated as a wholly-owned, first tier
Subsidiary of LSB and shall continue to be governed by the Laws of the State of
North Carolina as a state chartered bank, operating under the name "LSB". The
Merger shall be consummated pursuant to the terms of this Agreement, which has
been approved and adopted by the respective Boards of Directors of ONSB and LSB,
and the terms of the Plan of Merger to be entered into by LSB Bank and ONSB.

                  1.2 TIME AND PLACE OF CLOSING. The closing (the "Closing")
will take place at 9:00 A.M. (Eastern Standard Time) on the date that the
Effective Time occurs (or the immediately preceding day if the Effective Time is
earlier than 9:00 A.M.), or at such other time as the Parties, acting through
their chief executive officers or chairmen of the board of directors, may
mutually agree. The place of Closing shall be at the offices of Hunton &
Williams in Charlotte, North Carolina, or such other location as LSB shall
designate.

                  1.3 EFFECTIVE TIME. The Merger and other transactions
contemplated by this Agreement shall become effective on the date and at the
time the Articles of Merger reflecting the Merger shall become effective with
the Secretary of State of the State of North Carolina (the "Effective Time").
Subject to the terms and conditions hereof, unless otherwise mutually agreed
upon in writing by the chief executive officers or chairmen of the board of
directors of each Party, the Parties shall use their commercially reasonable
best efforts to cause the Effective Time to occur as soon as practicable
following the last to occur of (i) the effective date (including expiration of
any applicable waiting period) of the last required Consent of any Regulatory
Authority having authority over and approving or exempting the Merger, and (ii)
the date on which the shareholders of ONSB and LSB approve this Agreement and
the Plan of Merger to the extent such approval is required by applicable Law.

                                 TERMS OF MERGER

                  2.1 BUSINESS OF SURVIVING BANK. The business of the Surviving

property, franchises, and interests, including appointments, designations, and
nominations, and all other rights and interests as trustee, executor,

the Merger, including liabilities arising out of the operation of a trust
department; all rights of creditors and other obligees and all liens on property
of ONSB shall be preserved unimpaired; and all actions and legal proceedings to

accounts and deposits of ONSB shall be and continue to be accounts and deposits
of the Surviving Bank, without change in their respective terms, maturity,
minimum required balances or withdrawal value. As of the Effective Time, each
account or deposit of ONSB shall be considered for dividend or interest purposes
as an account or deposit of the Surviving Bank from the time said account or
deposit was opened in ONSB and at all times thereafter until such account or
deposit ceases to be an account or deposit of the Surviving Bank.

                  2.5 ARTICLES OF INCORPORATION. The Articles of Incorporation

                                    ARTICLE 3
                           MANNER OF CONVERTING SHARES

                  3.1 CONVERSION OF SHARES. Subject to the provisions of this 
Article 3, at the Effective Time, by virtue of the Merger and without any
action the part of LSB, LSB Bank, ONSB, or the shareholders of the foregoing,
the shares of the constituent corporations shall be converted as follows:

                  (a) Each share of LSB Common Stock issued and outstanding
         immediately prior to the Effective Time shall remain issued and
         outstanding from and after the Effective Time.

                  (b) Each share of LSB Bank Common Stock issued and outstanding
         immediately prior to the Effective Time shall remain issued and
         outstanding from and after the Effective Time.

                  (c) Each share of ONSB Common Stock (excluding shares held by
         (i) any ONSB Company or any LSB Company (in each case other than in a
         fiduciary capacity or as a result of debts previously contracted) which
         shares shall be canceled as provided in Section 3.3 hereof, and (ii)
         shareholders who perfect their statutory appraisal rights as provided
         in Section 3.4 hereof) issued and outstanding at the Effective Time
         shall cease to be outstanding and shall be converted into and exchanged
         for the right to receive 0.948 of a share of LSB Common Stock, subject
         to adjustment at Closing pursuant to subparagraphs a. and b. of this
         Section 3.1(c) (as adjusted, the "Exchange Ratio"):

                           a. If the Average LSB Closing Price is above $20.00
                  per share (subject to each Party's right to terminate this
                  Agreement set forth in Section 10.1(i) hereof), the "Exchange
                  Ratio" shall be adjusted and calculated in

                                        4

<PAGE>   10



                  accordance with the following equation (rounded to the nearest
                  one-thousandth):

                           ER = [[(ALCP*$250,000)+$25,000,000]/IOS]/ALCP

                   Where:

                     ER    =  Exchange Ratio.
                     ALCP  =  Average LSB Closing Price.
                     IOS   =  1,582,678 shares of ONSB Common Stock, less any
                              shares canceled as provided in Section 3.3 hereof.

                  For example, assuming that (i) the Average LSB Closing Price
                  is determined to be $23.00, and (ii) none of such shares are
                  canceled as provided in Section 3.3 hereof; then, the adjusted
                  Exchange Ratio would be 0.845.

                           b. If the Average LSB Closing Price is below $20.00
                  per share (subject to each Party's right to terminate this
                  Agreement set forth in Section 10.1(i) hereof), the "Exchange
                  Ratio" shall be adjusted and calculated (using the same
                  abbreviated terms as in subparagraph a. above) in accordance
                  with the following equation (rounded to the nearest one
                  one-thousandth):

                           ER = [[(ALCP*$1,000,000)+$10,000,000]/IOS]/ALCP

                  For example, assuming that (i) the Average LSB Closing Price
                  is determined to be $16.00, and (ii) none of such shares are
                  canceled as provided in Section 3.3 hereof; then, the adjusted
                  Exchange Ratio would be 1.027.

                  3.2 ANTI-DILUTION PROVISIONS. In the event LSB or ONSB (in
breach of Section 7.2 hereof) changes the number of shares of LSB Common Stock
or ONSB Common Stock, respectively, issued and outstanding prior to the
Effective Time as a result of a stock split, stock dividend, or similar
recapitalization with respect to such stock and the record date therefor (in the
case of a stock dividend) or the effective date thereof (in the case of a stock
split or similar recapitalization for which a record date is not established)
shall be prior to the Effective Time, the Exchange Ratio shall be
proportionately adjusted.

                  3.3 SHARES HELD BY ONSB OR LSB. Each of the shares of ONSB
Common Stock held by any ONSB Company or by any LSB Company, in each case other
than in a fiduciary capacity or as a result of debts previously contracted,
shall be canceled and retired at the Effective Time, and no consideration shall
be issued in exchange therefor.

                  3.4 DISSENTING SHAREHOLDERS. Any holder of shares of ONSB
Common Stock who perfects such holder's dissenters' rights of appraisal in
accordance with and as

                                        5

contemplated by Article 13 of the NCBCA shall be entitled to receive the value
of such shares in cash as determined pursuant to such provision of Law;
provided, however, that no such payment shall be made to any dissenting
shareholder unless and until such dissenting shareholder has complied with the
applicable provisions of the NCBCA and surrendered to the Surviving Bank the
certificate or certificates representing the shares for which payment is being
made. In the event that after the Effective Time a dissenting shareholder of
ONSB fails to perfect, or effectively withdraws or loses, such holder's right to
appraisal and of payment for such holder's shares, LSB shall issue and deliver
the consideration to which such holder of shares of ONSB Common Stock is
entitled under this Article 3 (without interest) upon surrender by such holder
of the certificate or certificates representing shares of ONSB Common Stock held
by such holder. ONSB will establish an escrow account with an amount sufficient
to satisfy the maximum aggregate payment that may be required to be paid to
dissenting shareholders. Upon satisfaction of all claims of dissenting
shareholders, the remaining escrowed amount, reduced by payment of the fees and
expenses of the escrow agent, will be returned to the Surviving Bank.

                  3.5 FRACTIONAL SHARES. Notwithstanding any other provision of
this Agreement, each holder of shares of ONSB Common Stock exchanged pursuant to
the Merger who would otherwise have been entitled to receive a fraction of a
share of LSB Common Stock (after taking into account all certificates delivered
by such holder) shall receive, in lieu thereof, cash (without interest) in an
amount equal to such fractional part of a share of LSB Common Stock multiplied
by the Average LSB Closing Price. No such holder will be entitled to dividends,
voting rights, or any other rights as a shareholder in respect of any fractional
shares.

                  3.6 CONVERSION OF STOCK OPTIONS AND WARRANTS; RESTRICTED
STOCK.

                  (a) At the Effective Time, each option, warrant or other right
         to purchase shares of ONSB Common Stock pursuant to stock options,
         warrants or stock appreciation rights ("ONSB Options") granted by ONSB
         under the ONSB Stock Plans or the ONSB Warrants, which are outstanding
         at the Effective Time, whether or not exercisable, shall be converted
         into and become rights with respect to LSB Common Stock, and LSB shall
         assume each ONSB Option, in accordance with the terms of the ONSB Stock
         Plan and stock option agreement or the ONSB Warrant, as the case may
         be, by which it is evidenced, except that from and after the Effective
         Time, (i) LSB and its Compensation Committee shall be substituted for
         ONSB and the Committee of ONSB's Board of Directors (including, if
         applicable, the entire Board of Directors of ONSB) administering such
         ONSB Stock Plan and ONSB Warrants, (ii) each ONSB Option assumed by LSB
         may be exercised solely for shares of LSB Common Stock (or cash in the
         case of stock appreciation rights), (iii) the number of shares of LSB
         Common Stock subject to such ONSB Option shall be equal to the number
         of shares of ONSB Common Stock subject to such ONSB Option immediately
         prior to the Effective Time multiplied by the Exchange Ratio, and (iv)
         the per share exercise price

                                        6

<PAGE>   12



         under each such ONSB Option shall be adjusted by dividing the per share
         exercise price under each such ONSB Option by the Exchange Ratio and
         rounding up to the nearest cent. Notwithstanding the provisions of
         clause (iii) of the preceding sentence, LSB shall not be obligated to
         issue any fraction of a share of LSB Common Stock upon exercise of ONSB
         Options and any fraction of a share of LSB Common Stock that otherwise
         would be subject to a converted ONSB Option shall represent the right
         to receive a cash payment upon exercise of such converted ONSB Option
         equal to the product of such fraction and the difference between the
         market value of one share of LSB Common Stock at the time of exercise
         of such Option and the per share exercise price of such ONSB Option.
         The market value of one share of LSB Common Stock at the time of
         exercise of an ONSB Option shall be the last sale price of such common
         stock on the Nasdaq/NMS (as reported by The Wall Street Journal or, if
         not reported thereby, any other authoritative source selected by LSB)
         on the last trading day preceding the date of exercise. In addition,
         notwithstanding the clauses (iii) and (iv) of the first sentence of
         this Section 3.6(a), each ONSB Option which is an "incentive stock
         option" shall be adjusted as required by Section 424 of the Internal
         Revenue Code, so as not to constitute a modification, extension or
         renewal of the option, within the meaning of Section 424(h) of the
         Internal Revenue Code. ONSB agrees to take all necessary steps to
         effectuate the foregoing provisions of this Section 3.6(a).

                  (b) As soon as practicable after the Effective Time, LSB shall
         deliver to the participants in each ONSB Stock Plan and the holders of
         the ONSB Warrants, as the case may be, an appropriate notice setting
         forth such participant's or holder's, as the case may be, rights
         pursuant thereto, and the grants pursuant to such ONSB Stock Plan and
         ONSB Warrants shall continue in effect on the same terms and conditions
         (subject to the adjustments required by Section 3.6(a) after giving
         effect to the Merger), and LSB shall comply with the terms of each ONSB
         Stock Plan to ensure, to the extent required by, and subject to the
         provisions of, such ONSB Stock Plan, that ONSB Options which qualified
         as incentive stock options prior to the Effective Time continue to
         qualify as incentive stock options after the Effective Time. At or
         prior to the Effective Time, LSB shall take all corporate action
         necessary to reserve for issuance sufficient shares of LSB Common Stock
         for delivery upon exercise ONSB Options assumed by it in accordance
         with this Section 3.6.

                  (c) All restrictions or limitations on transfer with respect
         to ONSB Common Stock awarded under the ONSB Stock Plans, the ONSB
         Warrants, or any other plan, program, or arrangement of any ONSB
         Company, to the extent that such restrictions or limitations shall not
         have already lapsed, and except as otherwise expressly provided in such
         plan, program, or arrangement, shall remain in full force and effect
         with respect to shares of LSB Common Stock into which such restricted
         stock is converted pursuant to Section 3.1 hereof.

<PAGE>   13



                  (d) Notwithstanding the foregoing provisions of this Section
         3.6, in no event shall options and warrants issued by ONSB to purchase
         more than 151,636 shares of ONSB Common Stock be converted into or
         become rights with respect to LSB Common Stock in connection with the
         transactions contemplated by this Agreement.



                                    ARTICLE 4
                               EXCHANGE OF SHARES

                  4.1 EXCHANGE PROCEDURES. Promptly after the Effective Time,
LSB shall cause the exchange agent selected by LSB (the "Exchange Agent") to
mail to the former shareholders of ONSB appropriate transmittal materials (which
shall specify that delivery shall be effected, and risk of loss and title to the
certificates theretofore representing shares of ONSB Common Stock shall pass,
only upon proper delivery of such certificates to the Exchange Agent. After the
Effective Time, each holder of shares of ONSB Common Stock (other than shares to
be canceled pursuant to Section 3.3 hereof or as to which statutory dissenters'
rights have been perfected as provided in Section 3.4 hereof) issued and
outstanding at the Effective Time shall surrender the certificate or
certificates representing such shares (or, if applicable, a lost certificate
affidavit (including indemnification) in form and substance reasonably
acceptable to LSB and the Exchange Agent) to the Exchange Agent and shall
promptly upon surrender thereof receive in exchange therefor the consideration
provided in Section 3.1 hereof, together with all undelivered dividends or
distributions in respect of such shares (without interest thereon) pursuant to
Section 4.2 hereof. To the extent required by Section 3.5 hereof, each holder of
shares of ONSB Common Stock issued and outstanding at the Effective Time also
shall receive, upon surrender of the certificate or certificates representing
such shares (or a lost certificate affidavit referenced above), cash in lieu of
any fractional share of LSB Common Stock to which such holder may be otherwise
entitled (without interest). LSB shall not be obligated to deliver the
consideration to which any former holder of ONSB Common Stock is entitled as a
result of the Merger until such holder surrenders such holder's certificate or
certificates representing the shares of ONSB Common Stock (or a lost certificate
affidavit referenced above) for exchange as provided in this Section 4.1. The
certificate or certificates of ONSB Common Stock so surrendered shall be duly
endorsed, or accompanied with executed blank stock powers with signatures
guaranteed, as the Exchange Agent may require. Any other provision of this
Agreement notwithstanding, neither LSB, the Surviving Bank nor the Exchange
Agent shall be liable to a holder of ONSB Common Stock for any amounts paid or
property delivered in good faith to a public official pursuant to any applicable
abandoned property Law.

                  4.2 RIGHTS OF FORMER ONSB SHAREHOLDERS. At the Effective Time,
the stock transfer books of ONSB shall be closed as to holders of ONSB Common
Stock immediately prior to the Effective Time, and no subsequent transfer of
ONSB Common

                                        8

<PAGE>   14



Stock by any such holder shall thereafter be made or recognized. Until
surrendered for exchange in accordance with the provisions of Section 4.1
hereof, each certificate theretofore representing shares of ONSB Common Stock
(other than shares to be canceled pursuant to Section 3.3 hereof or as to which
the holder thereof has perfected dissenters' rights of appraisal as contemplated
in Section 3.4 hereof) shall from and after the Effective Time represent for all
purposes only the right to receive the consideration provided in Sections 3.1
and 3.5 hereof; subject, however, to the Surviving Bank's obligation to pay any
dividends or make any other distributions with a record date prior to the
Effective Time which have been declared or made by ONSB in respect of such
shares of ONSB Common Stock in accordance with the terms of this Agreement and
which remain unpaid at the Effective Time. To the extent permitted by Law,
former shareholders of record of ONSB shall be entitled to vote after the
Effective Time at any meeting of LSB shareholders the number of whole shares of
LSB Common Stock into which their respective shares of ONSB Common Stock are
converted, regardless of whether such holders have exchanged their certificates
representing ONSB Common Stock for certificates representing LSB Common Stock in
accordance with the provisions of this Agreement. Whenever a dividend or other
distribution is declared by LSB on the LSB Common Stock, the record date for
which is at or after the Effective Time, the declaration shall include dividends
or other distributions on all shares of LSB Common Stock issuable pursuant to
this Agreement, but no dividend or other distribution payable to the holders of
record of LSB Common Stock as of any time subsequent to the Effective Time shall
be delivered to the holder of any certificate representing shares of ONSB Common
Stock issued and outstanding at the Effective Time until such holder surrenders
such certificate for exchange as provided in Section 4.1 hereof. However, upon
surrender of such ONSB Common Stock certificate, both the LSB Common Stock
certificate (together with all such undelivered dividends or other distributions
without interest) and any undelivered cash payments to be paid for fractional
share interests (without interest) shall be delivered and paid with respect to
each share represented by such certificate.


                                    ARTICLE 5
                     REPRESENTATIONS AND WARRANTIES OF ONSB

                  ONSB hereby represents and warrants to LSB and LSB Bank as
follows:

                  5.1 ORGANIZATION, STANDING AND POWER. ONSB is a state
chartered bank duly organized, validly existing, and in good standing under the
Laws of the State of North Carolina, and has the corporate power and authority
to carry on its business as now conducted and to own, lease and operate its
Assets. ONSB is duly qualified or licensed to transact business as a foreign
corporation in good standing in the States of the United States and foreign
jurisdictions where the character of its Assets or the nature or conduct of its
business requires it to be so qualified or licensed, except for such
jurisdictions in which the failure to be so qualified or licensed is not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on ONSB.

                                        9

<PAGE>   15




                  5.2 AUTHORITY; NO BREACH BY AGREEMENT.

                  (a) ONSB has the corporate power and authority necessary to
         execute, deliver, and perform its obligations under this Agreement, the
         Option Agreement, the Confidentiality Agreement and the Plan of Merger
         and to consummate the transactions contemplated hereby and thereby,
         subject to the approval of this Agreement and the Plan of Merger by the
         holders of two-thirds of the outstanding shares of ONSB Common Stock.
         The execution, delivery, and performance of this Agreement, the Option
         Agreement, the Confidentiality Agreement and the Plan of Merger and the
         consummation of the transactions contemplated herein and therein,
         including the Merger, have been duly and validly authorized by all
         necessary corporate action in respect thereof on the part of ONSB,
         subject to the approval of this Agreement and the Plan of Merger by the
         holders of two-thirds of the outstanding shares of ONSB Common Stock.
         Subject to such requisite shareholder approval, this Agreement, the
         Option Agreement and the Confidentiality Agreement represent, and, when
         executed and delivered, the Plan of Merger will represent, legal,
         valid, and binding obligations of ONSB, enforceable against ONSB in
         accordance with their respective terms (except in all cases as such
         enforceability may be limited by applicable bankruptcy, insolvency,
         reorganization, moratorium, or similar Laws affecting the enforcement
         of creditors' rights generally and except that the availability of the
         equitable remedy of specific performance or injunctive relief is
         subject to the discretion of the court before which any such proceeding
         may be brought).

                  (b) Neither the execution and delivery of this Agreement, the
         Option Agreement, the Confidentiality Agreement and the Plan of Merger
         by ONSB, nor the consummation by ONSB of the transactions contemplated
         hereby and thereby, nor compliance by ONSB with any of the provisions
         hereof and thereof, will (i) conflict with or result in a breach of any
         provision of ONSB's Articles of Incorporation or Bylaws, or (ii) except
         as disclosed in Section 5.2(b) of the ONSB Disclosure Memorandum,
         constitute or result in a Default under, or require any Consent
         pursuant to, or result in the creation of any Lien on any Asset of any
         ONSB Company under, any Contract or Permit of any ONSB Company, or,
         (iii) except as disclosed in Section 5.2(b) of the ONSB Disclosure
         Memorandum, violate any Law or Order applicable to any ONSB Company or
         any of their respective Assets.

                  (c) Except as disclosed in Section 5.2(c) of the ONSB
         Disclosure Memorandum, no notice to, filing with, or Consent of, any
         public body or authority is necessary for the consummation by ONSB of
         the Merger and the other transactions contemplated in this Agreement,
         the Option Agreement, the Confidentiality Agreement and the Plan of
         Merger.

                  5.3 CAPITAL STOCK.

                  (a) The authorized capital stock of ONSB consists of 2,000,000
         shares of ONSB Common Stock, of which 1,582,678 shares are issued and
         outstanding as of the date of this Agreement and not more than
         1,734,314 shares will be issued and outstanding at the Effective Time.
         All of the issued and outstanding shares of ONSB Common Stock are duly
         and validly issued and outstanding and are fully paid and
         nonassessable. None of the outstanding shares of ONSB Common Stock has
         been issued in violation of any preemptive rights of the current or
         past shareholders of ONSB. ONSB has reserved 111,294 shares of ONSB
         Common Stock for issuance under the ONSB Stock Plans, pursuant to which
         options to purchase not more than 111,294 shares of ONSB Common Stock
         are outstanding. ONSB has reserved 40,342 shares of ONSB Common Stock
         for issuance under the ONSB Warrants, pursuant to which warrants to
         purchase not more than 40,342 shares of ONSB Common Stock are
         outstanding.

                  (b) Except as set forth in Section 5.3(a) hereof, or as
         provided in the Option Agreement, there are no shares of capital stock
         or other equity securities of ONSB outstanding and no outstanding
         Rights relating to the capital stock of ONSB.

                  5.4 ONSB SUBSIDIARIES. ONSB has disclosed in Section 5.4 of
the ONSB Disclosure Memorandum all of the ONSB Subsidiaries as of the date of
this Agreement. Except as disclosed in Section 5.4 of the ONSB Disclosure
Memorandum, ONSB or one of its Subsidiaries owns all of the issued and
outstanding shares of capital stock of each ONSB Subsidiary. No equity
securities of any ONSB Subsidiary are or may become required to be issued (other
than to another ONSB Company) by reason of any Rights relating to the capital
stock of such ONSB Subsidiary, and there are no Contracts by which any ONSB
Subsidiary is bound to issue (other than to another ONSB Company) additional
shares of its capital stock or Rights relating thereto or by which any ONSB
Company is or may be bound to transfer any shares of the capital stock of any
ONSB Subsidiary (other than to another ONSB Company). There are no Contracts
relating to the rights of any ONSB Company to vote or to dispose of any shares
of the capital stock of any ONSB Subsidiary. All of the issued and outstanding
shares of capital stock of each ONSB Subsidiary are duly authorized, validly
issued and fully paid and nonassessable under the applicable corporation Law of
the jurisdiction in which such Subsidiary is incorporated or organized and are
owned by a ONSB Company free and clear of any Lien. Each ONSB Subsidiary is 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 has
the corporate power and authority necessary for it to own, lease, and operate
its Assets and to carry on its business as now conducted. Each ONSB Subsidiary
is duly qualified or licensed to transact business as a foreign corporation in
good standing in the States of the United States and foreign jurisdictions where
the character of its Assets or the nature or conduct of its business requires it
to be so qualified or licensed, except for such jurisdictions in which the
failure to be so qualified or licensed is not

                                       11

<PAGE>   17



reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on ONSB.

                  5.5 FINANCIAL STATEMENTS; REGULATORY AUTHORITY FILINGS.

                  (a) ONSB has disclosed in Section 5.5 of the ONSB Disclosure
         Memorandum, and has delivered to LSB copies of, all ONSB Financial
         Statements prepared for periods ended prior to the date hereof and will
         deliver to LSB copies of all ONSB Financial Statements prepared
         subsequent to the date hereof. The ONSB Financial Statements (as of the
         dates thereof and for the periods covered thereby): (i) are, or, if
         dated after the date of this Agreement, will be, in accordance with the
         books and records of the ONSB Companies, which are or will be, as the
         case may be, complete and correct and which have been or will have
         been, as the case may be, maintained in accordance with good business
         practices; and (ii) present or will present, as the case may be, fairly
         the consolidated financial position of the ONSB Companies as of the
         dates indicated and the consolidated results of operations, changes in
         shareholders' equity, and cash flows of the ONSB Companies for the
         periods indicated, in accordance with GAAP (subject to any exceptions
         as to consistency specified therein or as may be indicated in the notes
         thereto or, in the case of interim financial statements, to normal
         recurring year-end adjustments that are not material).

                  (b) ONSB has filed, and made copies available to LSB of, all
         forms, reports, and documents required to be filed by ONSB with the FRB
         or the FDIC since December 31, 1993 (collectively, the "ONSB FRB/FDIC
         Reports"). The ONSB FRB/FDIC Reports (i) at the time filed, complied in
         all material respects with the applicable requirements of the Laws that
         the FRB and the FDIC, as the case may be, are charged to administer and
         enforce, and (ii) did not at the time they were filed (or if amended or
         superseded by a filing prior to the date of this Agreement, then on the
         date of such filing) contain any untrue statement of a material fact or
         omit to state a material fact required to be stated in such ONSB
         FRB/FDIC Reports or necessary in order to make the statements in such
         ONSB FRB/FDIC Reports, in light of the circumstances under which they
         were made, not misleading. Except for ONSB Subsidiaries that are
         registered as a broker, dealer or investment advisor, neither ONSB nor
         any ONSB Subsidiary is required to file any forms, reports, or other
         documents with the SEC or NASD.

                  5.6 ABSENCE OF CERTAIN CHANGES OR EVENTS AND UNDISCLOSED
 LIABILITIES.

                  (a) Since September 30, 1996, (i) there have been no events,
         changes, or occurrences which have had, or are reasonably likely to
         have, individually or in the aggregate, a Material Adverse Effect on
         ONSB, and (ii) the ONSB Companies have not taken any action, or failed
         to take any action, prior to the date of this Agreement,

                                       12

<PAGE>   18



         which action or failure, if taken after the date of this Agreement,
         would represent or result in a material breach or violation of any of
         the covenants and agreements of ONSB provided in Article 7 hereof.

                  (b) No ONSB Company has any Liabilities that are reasonably
         likely to have, individually or in the aggregate, a Material Adverse
         Effect on ONSB, except Liabilities which are accrued or reserved
         against in the consolidated balance sheets of ONSB as of September 30,
         1996 included in the ONSB Financial Statements or reflected in the
         notes thereto. No ONSB Company has incurred or paid any Liability since
         September 30, 1996, except for such Liabilities incurred or paid in the
         ordinary course of business consistent with past business practice and
         which are not reasonably likely to have, individually or in the
         aggregate, a Material Adverse Effect on ONSB.

                  5.7 TAX MATTERS.

                  (a) All Tax Returns required to be filed by or on behalf of
         any of the ONSB Companies have been timely filed, or requests for
         extensions have been timely filed, granted, and have not expired for
         periods ended on or before December 31, 1995, and on or before the date
         of the most recent fiscal year end immediately preceding the Effective
         Time, and all Tax Returns filed are complete and accurate to the
         Knowledge of ONSB. All Taxes shown on filed Tax Returns have been paid.
         Except as disclosed in Section 5.7(a) of the ONSB Disclosure
         Memorandum, there is no audit examination, deficiency, or refund
         Litigation with respect to any Taxes. All Taxes and other Liabilities
         due with respect to completed and settled examinations or concluded
         Litigation have been paid.

                  (b) None of the ONSB Companies has executed an extension or
         waiver of any statute of limitations on the assessment or collection of
         any Tax due that is currently in effect.

                  (c) Adequate provision for any Taxes due or to become due for
         any of the ONSB Companies for the period or periods through and
         including the date of the respective ONSB Financial Statements has been
         made and is reflected on such ONSB Financial Statements.

                  (d) Deferred Taxes of the ONSB Companies have been provided
         for in the ONSB Financial Statements in accordance with GAAP.

                  (e) Each of the ONSB Companies is in compliance with, and its
         records contain all information and documents (including properly
         completed IRS Forms W-9) necessary to comply with, all applicable
         information reporting and Tax withholding requirements under federal,
         state, and local Tax Laws, and such records identify with specificity
         all accounts subject to backup withholding under Section 3406 of the

                                       13

<PAGE>   19



         Internal Revenue Code, except for such instances of noncompliance and
         such omissions as are not reasonably likely to have, individually or in
         the aggregate, a Material Adverse Effect on ONSB.

                  5.8 ASSETS. Except as disclosed or reserved against in the
ONSB Financial Statements, the ONSB Companies have good and marketable title,
free and clear of all Liens, to all of their respective Assets. All tangible
properties used in the businesses of the ONSB Companies are in good condition,
reasonable wear and tear excepted, and are usable in the ordinary course of
business consistent with ONSB's past practices. All Assets which are material to
the business of the ONSB Companies, held under leases or subleases by any of the
ONSB Companies, are held under valid Contracts enforceable in accordance with
their respective terms (except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, or other Laws affecting the
enforcement of creditors' rights generally and except that the availability of
the equitable remedy of specific performance or injunctive relief is subject to
the discretion of the court before which any proceedings may be brought), and
each such Contract is in full force and effect. The ONSB Companies currently
maintain insurance similar in amounts, scope, and coverage to that maintained by
other peer banking organizations. None of the ONSB Companies has received notice
from any insurance carrier that (i) such insurance will be canceled or that
coverage thereunder will be reduced or eliminated, or (ii) premium costs with
respect to such policies of insurance will be substantially increased. The
Assets of the ONSB Companies include all assets required to operate the business
of the ONSB Companies as presently conducted.

                  5.9 ENVIRONMENTAL MATTERS.

                  (a) To the Knowledge of ONSB, each ONSB Company, its
         Participation Facilities, and its Loan Properties are, and have been,
         in compliance with all Environmental Laws, except for violations which
         are not reasonably likely to have, individually or in the aggregate, a
         Material Adverse Effect on ONSB.

                  (b) There is no Litigation pending or, to the Knowledge of
         ONSB, threatened before any court, governmental agency, or board or
         other forum in which any ONSB Company or any of its Loan Properties or
         Participation Facilities has been or, with respect to threatened
         Litigation, may be named as a defendant or potentially responsible
         party (i) for alleged noncompliance (including by any predecessor) with
         any Environmental Law or (ii) relating to the release into the
         environment of any Hazardous Material, whether or not occurring at, on,
         under, or involving a site owned, leased, or operated by any ONSB
         Company or any of its Loan Properties or Participation Facilities.

                  (c) To the Knowledge of ONSB, there is no reasonable basis for
         any Litigation of a type described in subsection (b) above, except such
         as is not

                                       14

<PAGE>   20



         reasonably likely to have, individually or in the aggregate, a Material
         Adverse Effect on ONSB.

                  (d) To the Knowledge of ONSB, there have been no releases of
         Hazardous Materials in, on, under, or affecting any ONSB Company's
         current properties, or any Participation Facility or Loan Property of
         an ONSB Company, except such as are not reasonably likely to have,
         individually or in the aggregate, a Material Adverse Effect on ONSB.

                  5.10 COMPLIANCE WITH LAWS. ONSB is an "insured institution" as
defined in the Federal Deposit Insurance Act and applicable regulations
thereunder, and the deposits of ONSB are insured by the Bank Insurance Fund.
Each ONSB Company has in effect all Permits necessary for it to own, lease, or
operate its Assets and to carry on its business as now conducted, except for
those Permits the absence of which are not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on ONSB, and there
has occurred no Default under any such Permit, other than Defaults which are not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on ONSB. Except as disclosed in Section 5.10 of the ONSB Disclosure
Memorandum, no ONSB Company:

                  (a) Is in violation of any Laws, Orders, or Permits applicable
         to its business or employees conducting its business, except for
         violations which are not reasonably likely to have, individually or in
         the aggregate, a Material Adverse Effect on ONSB; and

                  (b) Has received any notification or communication from any
         agency or department of federal, state, or local government or any
         Regulatory Authority or the staff thereof (i) asserting that any ONSB
         Company is not in compliance with any of the Laws or Orders which such
         governmental authority or Regulatory Authority enforces, where such
         noncompliance is reasonably likely to have, individually or in the
         aggregate, a Material Adverse Effect on ONSB, (ii) threatening to
         revoke any Permits, the revocation of which is reasonably likely to
         have, individually or in the aggregate, a Material Adverse Effect on
         ONSB, or (iii) requiring any ONSB Company (A) to enter into or consent
         to the issuance of a cease and desist order, formal agreement,
         directive, commitment, or memorandum of understanding, or (B) to adopt
         any Board resolution or similar undertaking which restricts materially
         the conduct of its business, or in any manner relates to its capital
         adequacy, its credit or reserve policies, its management, or the
         payment of dividends.

                  5.11 LABOR RELATIONS. No ONSB Company is the subject of any
Litigation asserting that it or any other ONSB Company has committed an unfair
labor practice (within the meaning of the National Labor Relations Act or
comparable state law) or seeking to compel it or any other ONSB Company to
bargain with any labor organization as to wages or conditions of employment, nor
is any ONSB Company a party to or bound by any collective

                                       15

<PAGE>   21



bargaining agreement, contract, or other agreement or understanding with a labor
union or labor organization, nor is there any strike or other labor dispute
involving any ONSB Company, pending or threatened, or to the Knowledge of ONSB
is there any activity involving any ONSB Company's employees seeking to certify
a collective bargaining unit or engaging in any other organization activity.

                  5.12 EMPLOYEE BENEFIT PLANS.

                  (a) ONSB has disclosed in Section 5.12 of the ONSB Disclosure
         Memorandum, and has delivered or made available to LSB prior to the
         execution of this Agreement correct and complete copies, in each case,
         of all pension, retirement, profit-sharing, deferred compensation,
         stock option, employee stock ownership, severance pay, vacation, bonus,
         or other incentive plan, all other written employee programs,
         arrangements, or agreements, all medical, vision, dental, or other
         health plans, all life insurance plans, and all other employee benefit
         plans or fringe benefit plans, including, without limitation, "employee
         benefit plans" as that term is defined in Section 3(3) of ERISA,
         currently or previously adopted, maintained by, sponsored in whole or
         in part by, or contributed to by any ONSB Company or ERISA Affiliate
         thereof for the benefit of employees, retirees, dependents, spouses,
         directors, independent contractors, or other beneficiaries and under
         which employees, retirees, dependents, spouses, directors, independent
         contractors, or other beneficiaries are eligible to participate
         (collectively, the "ONSB Benefit Plans"). Any of the ONSB Benefit Plans
         which is an "employee pension benefit plan," as that term is defined in
         Section 3(1) of ERISA, is referred to herein as a "ONSB ERISA Plan."
         Any ONSB ERISA Plan which is also a "defined benefit plan" (as defined
         in Section 414(j) of the Internal Revenue Code or Section 3(35) of
         ERISA) is referred to herein as a "ONSB Pension Plan." On or after
         September 26, 1980, neither ONSB nor any ONSB Company has had an
         "obligation to contribute" (as defined in ERISA Section 4212) to a
         "multi-employer plan" (as defined in ERISA Sections 4001(a)(3) and
         3(37)(A)).

                  (b) ONSB has delivered or made available to LSB prior to the
         execution of this Agreement correct and complete copies of the
         following documents: (i) all trust agreements or other funding
         arrangements for such ONSB Benefit Plans (including insurance
         contracts), and all amendments thereto, (ii) with respect to any such
         ONSB Benefit Plans or amendments, all determination letters, rulings,
         opinion letters, information letters, or advisory opinions issued by
         the Internal Revenue Service, the United States Department of Labor, or
         the Pension Benefit Guaranty Corporation after December 31, 1974, (iii)
         annual reports or returns, audited or unaudited financial statements,
         actuarial valuations and reports, and summary annual reports prepared
         for any ONSB Benefit Plan with respect to the most recent three plan
         years, and (iv) the most recent summary plan descriptions and any
         material modifications thereto.


                                       16

<PAGE>   22



                  (c) All ONSB Benefit Plans are in compliance with the
         applicable terms of ERISA, the Internal Revenue Code, and any other
         applicable Laws, the breach or violation of which are reasonably likely
         to have, individually or in the aggregate, a Material Adverse Effect on
         ONSB. Each ONSB ERISA Plan which is intended to be qualified under
         Section 401(a) of the Internal Revenue Code has received a favorable
         determination letter from the Internal Revenue Service, and ONSB is not
         aware of any circumstances which will or could result in revocation of
         any such favorable determination letter. Each trust created under any
         ONSB ERISA Plan has been determined to be exempt from Tax under Section
         501(a) of the Internal Revenue Code and ONSB is not aware of any
         circumstance which will or could result in revocation of such
         exemption. With respect to each ONSB Benefit Plan, except as disclosed
         in Section 5.12(c) of the ONSB Disclosure Memorandum, no event has
         occurred which will or could give rise to a loss of any intended Tax
         consequences under the Internal Revenue Code or to any Tax under
         Section 511 of the Internal Revenue Code. There is no material pending
         or threatened Litigation relating to any ONSB ERISA Plan. No ONSB
         Company has engaged in a transaction with respect to any ONSB Benefit
         Plan that, assuming the taxable period of such transaction expired as
         of the date hereof, would subject any ONSB Company to a Tax or penalty
         imposed by either Section 4975 of the Internal Revenue Code or Section
         502(i) of ERISA in amounts which are reasonably likely to have,
         individually or in the aggregate, a Material Adverse Effect on ONSB.

                  (d) No ONSB Pension Plan has any "unfunded current liability,"
         as that term is defined in Section 302(d)(8)(A) of ERISA, and the fair
         market value of the assets of any such plan exceeds the plan's "benefit
         liabilities," as that term is defined in Section 4001 (a)(16) of ERISA,
         when determined under actuarial factors that would apply if the plan
         terminated in accordance with all applicable legal requirements. Since
         the date of the most recent actuarial valuation, there has been (i) no
         material change in the financial position of any ONSB Pension Plan,
         (ii) no change in the actuarial assumptions with respect to any ONSB
         Pension Plan, and (iii) no increase in benefits under any ONSB Pension
         Plan as a result of plan amendments or changes in applicable Law which
         is reasonably likely to have, individually or in the aggregate, a
         Material Adverse Effect on ONSB or materially adversely affect the
         funding status of such plan. Neither any ONSB Pension Plan nor any
         "single-employer plan," within the meaning of Section 4001(a)(15) of
         ERISA, currently or formerly maintained by any ONSB Company, or
         single-employer plan of any entity which is considered an employer with
         ONSB under Section 4001 of ERISA or Section 414 of the Internal Revenue
         Code or Section 302 of ERISA (whether or not waived) (an "ERISA
         Affiliate") has an "accumulated funding deficiency" within the meaning
         of Section 412 of the Internal Revenue Code or Section 302 of ERISA. No
         ONSB Company has provided, or is required to provide, security to a
         ONSB Pension Plan or to any single-employer plan of an ERISA Affiliate
         pursuant to Section 401(a)(29) of the Internal Revenue Code.

                                       17

<PAGE>   23




                  (e) No liability under Title IV of ERISA has been or is
         expected to be incurred by any ONSB Company with respect to any defined
         benefit plan currently or formerly maintained by any of them or by any
         ERISA Affiliate.

                  (f) No ONSB Company has any obligations for retiree health and
         life benefits under any of the ONSB Benefit Plans.

                  (g) Except as disclosed in Section 5.12 of the ONSB Disclosure
         Memorandum, neither the execution and delivery of this Agreement, the
         Option Agreement or the Plan of Merger nor the consummation of the
         transactions contemplated hereby and thereby will (i) result in any
         payment (including, without limitation, severance, unemployment
         compensation, golden parachute, or otherwise) becoming due to any
         director or any employee of any ONSB Company from any ONSB Company
         under any ONSB Benefit Plan or otherwise, (ii) increase any benefits
         otherwise payable under any ONSB Benefit Plan, or (iii) result in any
         acceleration of the time of payment or vesting of any such benefit.

                  (h) To the Knowledge of ONSB, no oral or written
         representation or communication with respect to any aspect of the ONSB
         Benefit Plans has been made to employees of any of the ONSB Companies
         prior to the date hereof which is not in accordance with the written or
         otherwise preexisting terms and provisions of such plans. All ONSB
         Benefit Plan documents and annual reports or returns, audited or
         unaudited financial statements, actuarial valuations, summary annual
         reports, and summary plan descriptions issued with respect to the ONSB
         Benefit Plans are correct and complete in all material respects and
         there have been no changes in the information set forth therein.

                  (i) Except as disclosed in Section 5.12(i) of the ONSB
         Disclosure Memorandum, none of the ONSB Companies has paid, or
         committed to pay, any bonus or commissions to any agent, manager or
         other employee of any ONSB Company with respect to any period
         commencing after December 31, 1995.

                  5.13 MATERIAL CONTRACTS. Except as disclosed in Section 5.13
of the ONSB Disclosure Memorandum, none of the ONSB Companies, nor any of their
respective Assets, businesses, or operations, is a party to, or is bound or
affected by, or receives benefits under: (i) any employment, severance,
termination, consulting, or retirement Contract providing for aggregate payments
to any Person in any calendar year in excess of $50,000; (ii) any Contract
relating to the borrowing of money by any ONSB Company or the guarantee by any
ONSB Company of any such obligation (other than Contracts evidencing deposit
liabilities, purchases of federal funds, fully-secured repurchase agreements,
and Federal Home Loan Bank advances of depository institution Subsidiaries,
trade payables, and Contracts relating to borrowings or guarantees made in the
ordinary course of business); (iii) any Contracts between or among ONSB
Companies; and (iv) any other Contract or

                                       18

<PAGE>   24



amendment thereto that would be required to be filed as an exhibit to a Form
10-K filed by ONSB with the SEC as of the date of this Agreement if ONSB were
required to file a Form 10-K with the SEC (together with all Contracts referred
to in Sections 5.8 and 5.12(a) hereof, the "ONSB Contracts"). With respect to
each ONSB Contract: (i) the Contract is in full force and effect; (ii) no ONSB
Company is in Default thereunder; (iii) no ONSB Company has repudiated or waived
any material provision of any such Contract; and (iv) no other party to any such
Contract is, to the Knowledge of ONSB, in Default in any respect, or has
repudiated or waived any material provision thereunder. Except as disclosed in
Section 5.13 of the ONSB Disclosure Memorandum, all of the indebtedness of any
ONSB Company for money borrowed is prepayable at any time by such ONSB Company
without penalty or premium.

                  5.14 LEGAL PROCEEDINGS. Except as disclosed in Section 5.14 of
the ONSB Disclosure Memorandum, there is no Litigation instituted or pending,
or, to the Knowledge of ONSB, threatened (or unasserted but considered probable
of assertion and which if asserted would have at least a reasonable probability
of an unfavorable outcome) against any ONSB Company, or against any Asset,
interest, or right of any of them, nor are there any Orders of any Regulatory
Authorities, other governmental authorities, or arbitrators outstanding against
any ONSB Company. Section 5.14 of the ONSB Disclosure Memorandum includes a
summary report of all Litigation as of the date of this Agreement to which any
ONSB Company is a party and in which the estimated maximum exposure is $50,000
or more.

                  5.15 REPORTS. Since January 1, 1992, or the date of
organization if later, each ONSB Company has timely filed all reports and
statements, together with any amendments required to be made with respect
thereto, that it was required to file with any Regulatory Authority. As of their
respective dates, each of such reports and documents, including the financial
statements, exhibits, and schedules thereto, complied in all material respects
with all applicable Laws. As of its respective date, each such report and
document did not, in all material respects, contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements made therein, in light of the circumstances
under which they were made, not misleading.

                  5.16 STATEMENTS TRUE AND CORRECT. None of the information
supplied or to be supplied by any ONSB Company or any Affiliate thereof for
inclusion in the Registration Statement to be filed by LSB with the SEC will,
when the Registration Statement becomes effective, be false or misleading with
respect to any material fact, or contain any untrue statement of material fact,
or omit to state any material fact required to be stated thereunder or necessary
to make the statements therein not misleading. None of the information supplied
or to be supplied by any ONSB Company or any Affiliate thereof for inclusion in
the ONSB Proxy Statement to be mailed to ONSB's shareholders in connection with
the Shareholders Meeting, and any other documents to be filed by a ONSB Company
or any Affiliate thereof with the SEC or any other Regulatory Authority in
connection with the

                                       19

<PAGE>   25



transactions contemplated hereby, will, at the respective time such documents
are filed, and with respect to the ONSB Proxy Statement, when first mailed to
the shareholders of ONSB, be false or misleading with respect to any material
fact, or contain any untrue statement of material fact, or omit to state any
material fact required to be stated thereunder or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or, in the case of the ONSB Proxy Statement or any amendment
thereof or supplement thereto, at the time of the Shareholders' Meeting, be
false or misleading with respect to any material fact, or omit to state any
material fact required to be stated thereunder or necessary to correct any
material statement in any earlier communication with respect to the solicitation
of any proxy for the Shareholders' Meeting. All documents that any ONSB Company
or any Affiliate thereof is responsible for filing with any Regulatory Authority
in connection with the transactions contemplated hereby will comply as to form
in all material respects with the provisions of applicable Law.

                  5.17 ACCOUNTING, TAX AND REGULATORY MATTERS. No ONSB Company
or any Affiliate thereof has taken any action, or agreed to take any action, or
has any Knowledge of any fact or circumstance that is reasonably likely to (i)
prevent the transactions contemplated hereby, including the Merger, from
qualifying, for "pooling-of-interests" accounting treatment consistent with GAAP
and the rules and regulations of the SEC or treatment as a "reorganization"
within the meaning of Section 368(a) of the Internal Revenue Code, or (ii)
materially impede or delay receipt of any Consents of Regulatory Authorities
referred to in Section 9.1(b) hereof or result in the imposition of a condition
or restriction of the type referred to in the last sentence of such Section.

                  5.18 STATE TAKEOVER LAWS. No action is necessary by any ONSB
Company to exempt the transactions contemplated by this Agreement from any
applicable "moratorium," "control share," "fair price," "business combination,"
or other anti-takeover Laws of the State of North Carolina (collectively,
"Takeover Laws"), including Articles 9 and 9A of the NCBCA.

                  5.19 CHARTER PROVISIONS. Each ONSB Company has taken all
action so that the entering into of this Agreement and the Option Agreement and
the consummation of the Merger and the other transactions contemplated by this
Agreement and the Option Agreement do not and will not result in the grant of
any rights to any Person (other than a LSB Company) under the Articles of
Incorporation, Bylaws, or other governing instruments of any ONSB Company or
restrict or impair the ability of LSB or any of its Subsidiaries to vote, or
otherwise to exercise the rights of a shareholder with respect to, shares of any
ONSB Company that may be directly or indirectly acquired or controlled by LSB.

                  5.20 SUPPORT AGREEMENTS. At least a majority of the 
directors of ONSB and the President and Chief Executive Officer and the Chairman
of the Board of ONSB have executed and delivered to LSB Support Agreements.

<PAGE>   26



                  5.21 DERIVATIVES CONTRACTS. Neither ONSB nor any of its
Subsidiaries is a party to or has agreed to enter into an exchange-traded or
over-the-counter swap, forward, future, option, cap, floor or collar financial
contract, or any other interest rate or foreign currency protection contract
that is not included in the ONSB Financial Statements, which is a financial
derivative contract (including various combinations thereof).

                  5.22 D&O INSURANCE. ONSB has (i) reported all claims to its
Knowledge under its past and present directors' and officers' liability
insurance policies in accordance with the terms and conditions of such policies
to permit coverage thereunder, and (ii) paid on a timely basis all premiums due
under such policies, and such policies have been in effect since the
organization of ONSB and no lapse of coverage has occurred since such date of
organization of ONSB.



                                    ARTICLE 6
                      REPRESENTATIONS AND WARRANTIES OF LSB

                  LSB and LSB Bank hereby jointly and severally represent and
warrant to ONSB as follows:

                  6.1 ORGANIZATION, STANDING AND POWER. LSB is a corporation
duly organized, validly existing, and in good standing under the Laws of the
State of North Carolina, and has the corporate power and authority to carry on
its business as now conducted and to own, lease and operate its Assets. LSB is
duly qualified or licensed to transact business as a foreign corporation in good
standing in the States of the United States and foreign jurisdictions where the
character of its Assets or the nature or conduct of its business requires it to
be so qualified or licensed, except for such jurisdictions in which the failure
to be so qualified or licensed is not reasonably likely to have, individually or
in the aggregate, a Material Adverse Effect on LSB.

                  6.2 AUTHORITY; NO BREACH BY AGREEMENT.

                  (a) LSB has the corporate power and authority necessary to
         execute, deliver and perform its obligations under this Agreement, the
         Option Agreement and the Confidentiality Agreement and to consummate
         the transactions contemplated hereby and thereby, subject to the
         approval of the issuance of LSB Common Stock contemplated herein by the
         holders of a majority of the outstanding shares of LSB Common Stock.
         The execution, delivery and performance of this Agreement, the Option
         Agreement and the Confidentiality Agreement and the consummation of the
         transactions contemplated herein and therein, including the Merger,
         have been duly and validly authorized by all necessary corporate action
         in respect thereof on the part of LSB, subject to the approval of the
         issuance of LSB Common Stock contemplated

                                       21

         herein by the holders of a majority of the outstanding shares of LSB
         Common Stock. Subject to such shareholder approval, this Agreement, the
         Option Agreement and the Confidentiality Agreement represent legal,
         valid, and binding obligations of LSB, enforceable against LSB in
         accordance with their respective terms (except in all cases as such
         enforceability may be limited by applicable bankruptcy, insolvency,
         reorganization, moratorium, or similar Laws affecting the enforcement
         of creditors' rights generally and except that the availability of the
         equitable remedy of specific performance or injunctive relief is
         subject to the discretion of the court before which any proceeding may
         be brought).

                  (b) Neither the execution and delivery of this Agreement, the
         Option Agreement and the Confidentiality Agreement by LSB, nor the
         consummation by LSB of the transactions contemplated hereby and
         thereby, nor compliance by LSB with any of the provisions hereof and
         thereof, will (i) conflict with or result in a breach of any provision
         of LSB's Articles of Incorporation or Bylaws, or (ii) except as
         disclosed in Section 6.2(b) of the LSB Disclosure Memorandum,
         constitute or result in a Default under, or require any Consent
         pursuant to, or result in the creation of any Lien on any Asset of any
         LSB Company under, any Contract or Permit of any LSB Company, or, (iii)
         except as disclosed in Section 6.2(b) of the LSB Disclosure Memorandum,
         violate any Law or Order applicable to any LSB Company or any of their
         respective Assets.

                  (c) Except as disclosed in Section 6.2(c) of the LSB
         Disclosure Memorandum, no notice to, filing with, or Consent of, any
         public body or authority is necessary for the consummation by LSB or
         LSB Bank of the Merger and the other transactions contemplated in this
         Agreement, the Option Agreement, the Confidentiality Agreement and the
         Plan of Merger.

                  6.3 CAPITAL STOCK.

                  (a) The authorized capital stock of LSB consists of 10,000,000
         shares of LSB Common Stock, of which 5,403,539 shares were issued and
         outstanding as of September 30, 1996. All of the issued and outstanding
         shares of LSB Common Stock are, and all of the shares of LSB Common
         Stock to be issued in exchange for shares of ONSB Common Stock upon
         consummation of the Merger, when issued in accordance with the terms of
         this Agreement, will be, duly and validly issued and outstanding and
         fully paid and nonassessable. None of the outstanding shares of LSB
         Common Stock has been, and none of the shares of LSB Common Stock to be
         issued in exchange for shares of ONSB Common Stock upon consummation of
         the Merger, will be, issued in violation of any preemptive rights of
         the current or past shareholders of LSB. LSB has reserved 750,000
         shares of LSB Common Stock for issuance under the LSB Stock Plans,
         pursuant to which options to purchase not more

                                       22

<PAGE>   28



         than 271,395 shares of LSB Common Stock were outstanding as of February
         21, 1997.

                  (b) Except as disclosed in Section 6.3(a) hereof, there are no
         shares of capital stock or other equity securities of LSB outstanding
         as of September 30, 1996 and no outstanding Rights relating to the
         capital stock of LSB as of February 21, 1997.


                  6.4 SEC FILINGS; FINANCIAL STATEMENTS.

                  (a) LSB has filed and made available to ONSB all forms,
         reports, and documents required to be filed by LSB with the SEC since
         December 31, 1993, other than registration statements on Forms S-4 and
         S-8 (collectively, the "LSB SEC Reports"). The LSB SEC Reports (i) at
         the time filed, complied in all material respects with the applicable
         requirements of the 1933 Act and the 1934 Act, as the case may be, and
         (ii) did not at the time they were filed (or if amended or superseded
         by a filing prior to the date of this Agreement, then on the date of
         such filing) contain any untrue statement of a material fact or omit to
         state a material fact required to be stated in such LSB SEC Reports or
         necessary in order to make the statements in such LSB SEC Reports, in
         light of the circumstances under which they were made, not misleading.

                  (b) Each of the LSB Financial Statements contained in the LSB
         SEC Reports, including any LSB SEC Reports filed after the date of this
         Agreement until the Effective Time, complied or will comply as to form
         in all material respects with the applicable published rules and
         regulations of the SEC with respect thereto, was or will be prepared in
         accordance with GAAP applied on a consistent basis throughout the
         periods involved (except as may be indicated in the notes to such
         financial statements or, in the case of unaudited statements, as
         permitted by Form 10-Q of the SEC), and fairly presented or will fairly
         present the consolidated financial position of LSB and its Subsidiaries
         as at the respective dates and the consolidated results of its
         operations and cash flows for the periods indicated, except that the
         unaudited interim financial statements were or are subject to normal
         and recurring year-end adjustments which were nor or are not expected
         to be material in amount.

                  6.5 ABSENCE OF CERTAIN CHANGES OR EVENTS AND UNDISCLOSED
         LIABILITIES.

                  (a) Since September 30, 1996, (i) there have been no events,
         changes or occurrences which have had, or are reasonably likely to
         have, individually or in the aggregate, a Material Adverse Effect on
         LSB, and (ii) the LSB Companies have not taken any action, or failed to
         take any action, prior to the date of this Agreement, which action or
         failure, if taken after the date of this Agreement, would represent or

                                       23

<PAGE>   29



         result in a material breach or violation of any of the covenants and
         agreements of LSB provided in Article 7 hereof.

                  (b) No LSB Company has any Liabilities that are reasonably
         likely to have, individually or in the aggregate, a Material Adverse
         Effect on LSB, except Liabilities which are accrued or reserved against
         in the consolidated balance sheets of LSB as of September 30, 1996
         included in the LSB Financial Statements or reflected in the notes
         thereto. No LSB Company has incurred or paid any Liability since
         September 30, 1996, except for such Liabilities incurred or paid in the
         ordinary course of business consistent with past business practice and
         which are not reasonably likely to have, individually or in the
         aggregate, a Material Adverse Effect on LSB.

                  6.6 TAX MATTERS.

                  (a) All Tax Returns required to be filed by or on behalf of
         any of the LSB Companies have been timely filed, or requests for
         extensions have been timely filed, granted, and have not expired for
         periods ended on or before December 31, 1995, and on or before the date
         of the most recent fiscal year end immediately preceding the Effective
         Time, and all Tax Returns filed are complete and accurate to the
         Knowledge of LSB. All Taxes shown on filed returns have been paid.
         Except as disclosed in Section 6.6(a) of the LSB Disclosure Memoranda,
         there is no audit examination, deficiency, or refund Litigation with
         respect to any Taxes. All Taxes and other Liabilities due with respect
         to completed and settled examinations or concluded Litigation have been
         paid.

                  (b) None of the LSB Companies has executed an extension or
         waiver of any statute of limitations on the assessment or collection of
         any Tax due that is currently in effect.

                  (c) Adequate provision for any Taxes due or to become due for
         any of the LSB Companies for the period or periods through and
         including the date of the respective LSB Financial Statements has been
         made and is reflected on such LSB Financial Statements.

                  (d) Deferred Taxes of the LSB Companies have been provided for
         in the LSB Financial Statements in accordance with GAAP.

                  6.7 COMPLIANCE WITH LAWS. LSB is duly registered as a bank
holding company under the BHC Act. Each LSB Company has in effect all Permits
necessary for it to own, lease or operate its Assets and to carry on its
business as now conducted, except for those Permits the absence of which is not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on LSB, and there has occurred no Default under any such Permit, other
than Defaults which are not reasonably likely to have, individually or in

                                       24

<PAGE>   30



the aggregate, a Material Adverse Effect on LSB. Except as disclosed in Section
6.7 of the LSB Disclosure Memorandum, no LSB Company:

                  (a) is in violation of any Laws, Orders or Permits applicable
         to its business or employees conducting its business, except for
         violations which are not reasonably likely to have, individually or in
         the aggregate, a Material Adverse Effect on LSB; and

                  (b) has received any notification or communication from any
         agency or department of federal, state, or local government or any
         Regulatory Authority or the staff thereof (i) asserting that any LSB
         Company is not in compliance with any of the Laws or Orders which such
         governmental authority or Regulatory Authority enforces, where such
         noncompliance is reasonably likely to have, individually or in the
         aggregate, a Material Adverse Effect on LSB, (ii) threatening to revoke
         any Permits, the revocation of which is reasonably likely to have,
         individually or in the aggregate, a Material Adverse Effect on LSB, or
         (iii) requiring any LSB Company (A) to enter into or consent to the
         issuance of a cease and desist order, formal agreement, directive,
         commitment or memorandum of understanding, or (B) to adopt any Board or
         similar undertaking, which restricts materially the conduct of its
         business, or in any manner relates to its capital adequacy, its credit
         or reserve policies, its management, or the payment of dividends.

                  6.8 LEGAL PROCEEDINGS. Except as disclosed in Section 6.8 of
the LSB Disclosure Memorandum, there is no Litigation instituted or pending, or,
to the Knowledge of LSB, threatened (or unasserted but considered probable of
assertion and which if asserted would have at least a reasonable probability of
an unfavorable outcome) against any LSB Company, or against any Asset, interest,
or right of any of them that is reasonably likely to have, individually or in
the aggregate, a Material Adverse Effect on LSB, nor are the any Orders of any
Regulatory Authorities, other governmental authorities, or arbitrators
outstanding against any LSB Company, that are reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on LSB.

                  6.9 REPORTS. Since January 1, 1992, or the date of
organization if later, each LSB Company has timely filed all reports and
statements, together with any amendments required to be made with respect
thereto, that it was required to file with (i) the SEC, including, but not
limited to, Forms 10-K, Forms 10-Q, Form 8-K, and proxy statements; (ii) other
Regulatory Authorities; and (iii) any applicable state securities or banking
authorities (except, in the case of state securities authorities, failures to
file which are not reasonably likely to have, individually or in the aggregate,
a Material Adverse Effect on LSB). As of their respective date, each of such
reports and documents, including the financial statements, exhibits, and
schedules thereto, complied in all material respects with all applicable Laws.
As of its respective date, each such report and document did not, in all
material respects, contain any untrue statement of a material fact or omit to
state a material

                                       25

<PAGE>   31



fact required to be stated therein or necessary to make the statements made
therein, in light of the circumstances under which they were made, not
misleading.

                  6.10 STATEMENTS TRUE AND CORRECT. None of the information
supplied or to be supplied by any LSB Company or any Affiliate thereof for
inclusion in the Registration Statement to be filed by LSB with the SEC, will,
when the Registration Statement becomes effective, be false or misleading with
respect to any material fact, or contain any untrue statement of a material
fact, or omit to state any material fact required to be stated thereunder or
necessary to make the statements therein not misleading. None of the information
supplied or to be supplied by any LSB Company or any Affiliate thereof for
inclusion in the ONSB Proxy Statement to be mailed to ONSB's shareholders in
connection with the Shareholders' Meeting, and any other documents to be filed
by any LSB Company or any Affiliate thereof with the SEC or any other Regulatory
Authority in connection with the transactions contemplated hereby, will, at the
respective time such documents are filed, and with respect to the ONSB Proxy
Statement, when first mailed to the shareholders of ONSB, be false or misleading
with respect to any material fact, or contain any untrue statement of a material
fact, or omit to state any material fact required to be stated thereunder or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, or, in the case of the ONSB Proxy
Statement or any amendment thereof or supplement thereto, at the time of the
Shareholders' Meeting, be false or misleading with respect to any material fact,
or contain any untrue statements of material fact, or omit to state any material
fact required to be stated thereunder or necessary to correct any statement in
any earlier communication with respect to the solicitation of any proxy for the
Shareholders' Meeting. All documents that any LSB Company or any Affiliate
thereof is responsible for filing with any Regulatory Authority in connection
with the transactions contemplated hereby will comply as to form in all material
respects with the provisions of applicable Law.

                  6.11 ACCOUNTING, TAX AND REGULATORY MATTERS. No LSB Company or
any Affiliate thereof has taken any action, or agreed to take any action, or has
any Knowledge of any fact or circumstance that is reasonably likely to (i)
prevent the transactions contemplated hereby, including the Merger, from
qualifying for "pooling-of-interests" accounting treatment consistent with GAAP
and the rules and regulations of the SEC or treatment as a "reorganization"
within the meaning of Section 368(a) of the Internal Revenue Code, or (ii)
materially impede or delay receipt of any Consents of Regulatory Authorities
referred to in Section 9.1(b) hereof or result in the imposition of a condition
or restriction of the type referred to in the last sentence of such Section.

                  6.12 AUTHORITY OF LSB BANK. LSB Bank is a state chartered bank
duly organized, validly existing, and in good standing under the Laws of the
State of North Carolina as a wholly owned, first tier Subsidiary of LSB. LSB
Bank has the corporate power and authority necessary to execute, deliver, and
perform its obligations under this Agreement and the Plan of Merger and to
consummate the transactions contemplated hereby

                                       26

<PAGE>   32



and thereby, subject to the approval of this Agreement and the Plan of Merger by
LSB, its sole shareholder. The execution, delivery, and performance of this
Agreement and the Plan of Merger and the consummation of the transactions
contemplated herein and therein, including the Merger, will be duly and validly
authorized by all necessary corporate action in respect thereof on the part of
LSB Bank, subject to the approval of this Agreement and the Plan of Merger by
LSB, its sole shareholder. Subject to such shareholder approval, this Agreement,
and, when executed and delivered, the Plan of Merger will, represent legal,
valid, and binding obligations of LSB Bank, enforceable against LSB Bank in
accordance with their respective terms (except in all cases as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, or similar Laws affecting the enforcement of
creditors' rights generally and except that the availability of the equitable
remedy of specific performance or injunctive relief is subject to the discretion
of the court before which any proceeding may be brought).

                  6.13 ENVIRONMENTAL MATTERS.

                  (a) To the Knowledge of LSB, each LSB Company, its
         Participation Facilities, and its Loan Properties are, and have been,
         in compliance with all Environmental Laws, except for violations which
         are not reasonably likely to have, individually or in the aggregate, a
         Material Adverse Effect on LSB.

                  (b) There is no Litigation pending or, to the Knowledge of
         LSB, threatened before any court, governmental agency, or board or
         other forum in which any LSB Company or any of its Loan Properties or
         Participation Facilities has been or, with respect to threatened
         Litigation, may be named as a defendant or potentially responsible
         party (i) for alleged noncompliance (including by any predecessor) with
         any Environmental Law or (ii) relating to the release into the
         environment of any Hazardous Material, whether or not occurring at, on,
         under, or involving a site owned, leased, or operated by any LSB
         Company or any of its Loan Properties or Participation Facilities.

                  (c) To the Knowledge of LSB, there is no reasonable basis for
         any Litigation of a type described in subsection (b) above, except such
         as is not reasonably likely to have, individually or in the aggregate,
         a Material Adverse Effect on LSB.

                  (d) To the Knowledge of LSB, there have been no releases of
         Hazardous Materials in, on, under, or affecting any LSB Company's
         current properties, or any Participation Facility or Loan Property of
         an LSB Company, except such as are not reasonably likely to have,
         individually or in the aggregate, a Material Adverse Effect on LSB.


                                       27

<PAGE>   33



                  6.14 LABOR RELATIONS. No LSB Company is the subject of any
Litigation asserting that it or any other LSB Company has committed an unfair
labor practice (within the meaning of the National Labor Relations Act or
comparable state law) or seeking to compel it or any other LSB Company to
bargain with any labor organization as to wages or conditions of employment, nor
is any LSB Company a party to or bound by any collective bargaining agreement,
contract, or other agreement or understanding with a labor union or labor
organization, nor is there any strike or other labor dispute involving any LSB
Company, pending or threatened, or to the Knowledge of LSB is there any activity
involving any LSB Company's employees seeking to certify a collective bargaining
unit or engaging in any other organization activity.

                  6.15 EMPLOYEE BENEFIT PLANS.

                  (a) LSB has disclosed in Section 6.15 of the LSB Disclosure
         Memorandum, and has delivered or made available to ONSB prior to the
         execution of this Agreement correct and complete copies, in each case,
         of all pension, retirement, profit-sharing, deferred compensation,
         stock option, employee stock ownership, severance pay, vacation, bonus,
         or other incentive plan, all other written employee programs,
         arrangements, or agreements, all medical, vision, dental, or other
         health plans, all life insurance plans, and all other employee benefit
         plans or fringe benefit plans, including, without limitation, "employee
         benefit plans" as that term is defined in Section 3(3) of ERISA,
         currently or previously adopted, maintained by, sponsored in whole or
         in part by, or contributed to by any LSB Company or ERISA Affiliate
         thereof for the benefit of employees, retirees, dependents, spouses,
         directors, independent contractors, or other beneficiaries and under
         which employees, retirees, dependents, spouses, directors, independent
         contractors, or other beneficiaries are eligible to participate
         (collectively, the "LSB Benefit Plans"). Any of the LSB Benefit Plans
         which is an "employee pension benefit plan," as that term is defined in
         Section 3(1) of ERISA, is referred to herein as a "LSB ERISA Plan." Any
         LSB ERISA Plan which is also a "defined benefit plan" (as defined in
         Section 414(j) of the Internal Revenue Code or Section 3(35) of ERISA)
         is referred to herein as a "LSB Pension Plan." On or after September
         26, 1980, neither LSB nor any LSB Company has had an "obligation to
         contribute" (as defined in ERISA Section 4212) to a "multi-employer
         plan" (as defined in ERISA Sections 4001(a)(3) and 3(37)(A)).

                  (b) LSB has delivered or made available to ONSB prior to the
         execution of this Agreement correct and complete copies of the
         following documents: (i) all trust agreements or other funding
         arrangements for such LSB Benefit Plans (including insurance
         contracts), and all amendments thereto, (ii) with respect to any such
         LSB Benefit Plans or amendments, all determination letters, rulings,
         opinion letters, information letters, or advisory opinions issued by
         the Internal Revenue Service, the United States Department of Labor, or
         the Pension Benefit Guaranty Corporation after December 31, 1974, (iii)
         annual reports or returns, audited or unaudited financial

                                       28

<PAGE>   34



         statements, actuarial valuations and reports, and summary annual
         reports prepared for any LSB Benefit Plan with respect to the most
         recent three plan years, and (iv) the most recent summary plan
         descriptions and any material modifications thereto.

                  (c) All LSB Benefit Plans are in compliance with the
         applicable terms of ERISA, the Internal Revenue Code, and any other
         applicable Laws, the breach or violation of which are reasonably likely
         to have, individually or in the aggregate, a Material Adverse Effect on
         LSB. Each LSB ERISA Plan which is intended to be qualified under
         Section 401(a) of the Internal Revenue Code has received a favorable
         determination letter from the Internal Revenue Service, and LSB is not
         aware of any circumstances which will or could result in revocation of
         any such favorable determination letter. Each trust created under any
         LSB ERISA Plan has been determined to be exempt from Tax under Section
         501(a) of the Internal Revenue Code and LSB is not aware of any
         circumstance which will or could result in revocation of such
         exemption. With respect to each LSB Benefit Plan, except as disclosed
         in Section 6.15(c) of the LSB Disclosure Memorandum, no event has
         occurred which will or could give rise to a loss of any intended Tax
         consequences under the Internal Revenue Code or to any Tax under
         Section 511 of the Internal Revenue Code. There is no material pending
         or threatened Litigation relating to any LSB ERISA Plan. No LSB Company
         has engaged in a transaction with respect to any LSB Benefit Plan that,
         assuming the taxable period of such transaction expired as of the date
         hereof, would subject any LSB Company to a Tax or penalty imposed by
         either Section 4975 of the Internal Revenue Code or Section 502(i) of
         ERISA in amounts which are reasonably likely to have, individually or
         in the aggregate, a Material Adverse Effect on LSB.

                  (d) No LSB Pension Plan has any "unfunded current liability,"
         as that term is defined in Section 302(d)(8)(A) of ERISA, and the fair
         market value of the assets of any such plan exceeds the plan's "benefit
         liabilities," as that term is defined in Section 4001 (a)(16) of ERISA,
         when determined under actuarial factors that would apply if the plan
         terminated in accordance with all applicable legal requirements. Since
         the date of the most recent actuarial valuation, there has been (i) no
         material change in the financial position of any LSB Pension Plan, (ii)
         no change in the actuarial assumptions with respect to any LSB Pension
         Plan, and (iii) no increase in benefits under any LSB Pension Plan as a
         result of plan amendments or changes in applicable Law which is
         reasonably likely to have, individually or in the aggregate, a Material
         Adverse Effect on LSB or materially adversely affect the funding status
         of such plan. Neither any LSB Pension Plan nor any "single-employer
         plan," within the meaning of Section 4001(a)(15) of ERISA, currently or
         formerly maintained by any LSB Company, or single-employer plan of any
         entity which is considered an employer with LSB under Section 4001 of
         ERISA or Section 414 of the Internal Revenue Code or Section 302 of
         ERISA (whether or not waived) (an "ERISA Affiliate") has an
         "accumulated funding deficiency" within the meaning of Section 412 of
         the Internal Revenue Code or Section 302 of ERISA. No LSB Company has

                                       29

         provided, or is required to provide, security to a LSB Pension Plan or
         to any single-employer plan of an ERISA Affiliate pursuant to Section
         401(a)(29) of the Internal Revenue Code.

                  (e) No liability under Title IV of ERISA has been or is
         expected to be incurred by any LSB Company with respect to any defined
         benefit plan currently or formerly maintained by any of them or by any
         ERISA Affiliate.

                  (f) Except as disclosed in Section 6.15(f) of the LSB
         Disclosure Memorandum, no LSB Company has any obligations for retiree
         health and life benefits under any of the LSB Benefit Plans.

                  (g) Except as disclosed in Section 6.15(g) of the LSB
         Disclosure Memorandum, neither the execution and delivery of this
         Agreement, the Option Agreement or the Plan of Merger nor the
         consummation of the transactions contemplated hereby and thereby will
         (i) result in any payment (including, without limitation, severance,
         unemployment compensation, golden parachute, or otherwise) becoming due
         to any director or any employee of any LSB Company from any LSB Company
         under any LSB Benefit Plan or otherwise, (ii) increase any benefits
         otherwise payable under any LSB Benefit Plan, or (iii) result in any
         acceleration of the time of payment or vesting of any such benefit.

                  (h) To the Knowledge of LSB, no oral or written representation
         or communication with respect to any aspect of the LSB Benefit Plans
         has been made to employees of any of the LSB Companies prior to the
         date hereof which is not in accordance with the written or otherwise
         preexisting terms and provisions of such plans. All LSB Benefit Plan
         documents and annual reports or returns, audited or unaudited financial
         statements, actuarial valuations, summary annual reports, and summary
         plan descriptions issued with respect to the LSB Benefit Plans are
         correct and complete in all material respects and there have been no
         changes in the information set forth therein.

the earlier of the Effective Time or the termination of this Agreement in
accordance with Article 10 hereof, LSB covenants and agrees that it shall (a)
continue to conduct its business and the business of its Subsidiaries in a
manner, designed in its reasonable judgment, to enhance the long-term value of
the LSB Common Stock and the business prospects of the LSB Companies and to the
extent consistent therewith use all commercially reasonable best efforts to
preserve intact the LSB Companies' core businesses and goodwill with their
respective employees and the communities they serve, and (b) take no action
which would (i) materially adversely affect the ability of any Party to obtain
any Consents required for the transactions contemplated hereby without
imposition of a condition or restriction of the type referred to in the last
sentence of Section 9.1(b) hereof, or (ii) materially adversely affect the
ability of any Party to perform its covenants and agreements under this
Agreement; provided, that the foregoing shall not prevent any LSB Company from
acquiring any other company or discontinuing or disposing of any of its Assets
or business if such action is, in the judgment of LSB, desirable in the conduct
of the business of LSB and its Subsidiaries. LSB further covenants and agrees
that it will not: (x) without the prior written consent of the chief executive
officer, president or chairman of the Board of ONSB, amend the Articles of
Incorporation or Bylaws of LSB, in each case, in any manner adverse to the
holders of ONSB Common Stock, or (y) declare and pay any cash dividends on the
LSB Common Stock except for regular cash dividends on the LSB Common Stock with
record and payment dates in accordance with LSB's past record dates for cash
dividends.

                  7.4 ADVERSE CHANGES IN CONDITION. Each Party agrees to give
written notice promptly to the other Party upon becoming aware of the occurrence
or impending occurrence of any event or circumstance relating to it or any of
its Subsidiaries which (i) is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on it,

                                       33

<PAGE>   39



or (ii) is reasonable likely to cause or constitute a material breach of any of
its representations, warranties, or covenants contained herein, and to use its
commercially reasonable best efforts to prevent or promptly to remedy the same.

                  7.5 REPORTS. Each Party and its Subsidiaries shall file all
reports required to be filed by it with Regulatory Authorities between the date
of this Agreement and the Effective Time and such Party shall deliver to the
other Party copies of all such reports filed by such Party and its Subsidiaries
promptly after the same are filed. If financial statements are contained in any
such reports filed with the SEC, in the case of LSB, or the FRB, in the case of
ONSB, such financial statements will fairly present the consolidated financial
position of the entity filing such statements as of the dates indicated and the
consolidated results of operations, changes in shareholders' equity, and cash
flows for the periods then ended in accordance with GAAP (subject in the case of
interim financial statements to normal recurring year-end adjustments that are
not material). As of their respective dates, such reports filed with the SEC or
the FRB, as the case may be, will comply in all material respects with the
Securities Laws, in the case of reports filed with the SEC, and the applicable
Laws enforced by the FRB, in the case of reports filed with the FRB, and will
not contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. Any financial statements contained in any other reports to another
Regulatory Authority shall be prepared in accordance with Laws applicable to
such reports.

                  7.6 ONSB RIGHT TO RECOMMEND DIRECTORS; ADDITIONAL OFFICERS.
From the date of this Agreement until the earlier of the date ten (10) days
prior to the scheduled Closing Date or the termination of this Agreement in
accordance with Article 10 hereof, ONSB shall have the right (subject to
shareholder requirement and age restrictions in the Bylaws of LSB) to (i)
recommend candidates to fill two (2) additional directorships on the class of
directors which terms expire at the 1998 annual meeting of LSB shareholders (the
"1998 Class"), which two additional directorships on the 1998 Class LSB's Board
of Directors will authorize on or before the Closing Date (expanding the Board
from 12 to 14 directorships), and (ii) specify which of those candidates shall
be reelected upon expiration of his or her term to fill (x) one (1) additional
directorship on the class of directors which terms expire at the 1999 annual
meeting of LSB shareholders (the "1999 Class"), and (y) one (1) additional
directorship on the class of directors which terms expire at the 2000 annual
meeting of LSB shareholders (the "2000 Class"), which additional directorships
on the 1999 Class and the 2000 Class LSB's Board of Directors will authorize on
or before the 1998 annual meeting of LSB shareholders. LSB shall notify ONSB in
writing of its Board's decisions whether to accept or reject candidates
recommended by ONSB to fill such two (2) additional directorships on the 1998
Class and to fill such additional directorships on the 1999 Class and the 2000
Class. Prior to the Effective Time, LSB's Board of Directors shall (subject to
shareholder requirement and age restrictions in the Bylaws of LSB) elect the two
candidates accepted by the LSB Board to fill the two (2) additional
directorships on the 1998

                                       34

Class, provided such elections shall be contingent and become effective upon the
Closing of the Merger, and in connection with the 1998 annual meeting of LSB
shareholders, LSB's Board of Directors shall (subject to the Articles of
Incorporation and Bylaws of LSB and the occurrence of the Merger) recommend in
the proxy statement to the LSB shareholders the election of the particular
candidates accepted by the LSB Board to fill the one (1) additional directorship
on the 1999 Class and the one (1) additional directorship on the 2000 Class.
Notwithstanding anything to the contrary in this Section, the LSB Board may
reject any person(s) recommended by ONSB pursuant to this Section which in the
reasonable good faith judgment of the LSB Board could reasonably likely have an
adverse effect upon the LSB Board's ability to deliberate and take actions for
the benefit of the shareholders of LSB. Shortly after the election to LSB's
Board of Directors of the candidates recommended by ONSB as provided above (and
prior to the Effective Time with respect to candidates to fill the additional
directorships on the 1998 Class), LSB shall (subject to the Articles of
Incorporation and Bylaws of LSB Bank) cause such persons to be elected to LSB
Bank's Board of Directors for the same terms as such persons will serve as
directors on LSB's Board of Directors. Prior to the Effective Time, LSB Bank's
Board of Directors shall (subject to the Articles of Incorporation and Bylaws of
LSB Bank) appoint Nicholas A. Daves to the office of Senior Vice President of
LSB Bank, Charles V. Darnell to the office of Senior Vice President of LSB Bank,
Suzanne J. Bullotta to the office of Senior Vice President of LSB Bank, and all
other officers of ONSB to offices at LSB Bank that carries titles equivalent to
the titles held by such officers at ONSB (except for the corporate secretary of
ONSB that shall be appointed as an assistant corporate secretary of LSB Bank),
provided such appointments shall be contingent and become effective upon the
Closing of the Merger.

                  7.7 ONSB'S DISPOSITION OF FEDERAL RESERVE BANK STOCK. Prior to
the Effective Time, ONSB shall, and shall cause each of its Subsidiaries to,
take all necessary steps to sell or cause the cancellation of any and all shares
of Federal Reserve Bank stock owned by ONSB and its Subsidiaries.

advised in writing by counsel to such Board) use their commercially reasonable
best efforts to obtain such shareholders' approval.

                  8.2 NASDAQ/NMS LISTING. LSB shall, prior to the Effective

use their commercially reasonable best efforts to obtain the requisite Consents
of all Regulatory Authorities as soon as reasonably practical after the filing
of the appropriate applications.

                  8.4 AGREEMENT AS TO EFFORTS TO CONSUMMATE. Subject to the
terms and conditions of this Agreement, each Party agrees to use, and to cause
its Subsidiaries to use, its commercially reasonable best efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, all things
necessary, proper, or advisable under applicable Laws to consummate and make
effective, as soon as practicable after the date of this Agreement, the
transactions contemplated by this Agreement, including, which limitation, using
its commercially reasonable best efforts to lift or rescind any Order adversely
affecting its ability to consummate the transactions contemplated herein and to
cause to be satisfied the conditions applicable to such Party referred to in
Article 9 hereof; provided, that nothing herein shall preclude either Party from
exercising its rights under this Agreement or the Option Agreement. Each Party
shall use, and shall cause each of its Subsidiaries to use, its

                                       36

<PAGE>   42



commercially reasonable best efforts to obtain all Consents necessary or

Agreement.

                  8.5 INVESTIGATION AND CONFIDENTIALITY.

                  (a) Prior to the Effective Time, each Party shall keep the
         other Party advised of all material developments relevant to its
         business and to consummation of the Merger and shall permit the other
         Party and its Representatives to make or cause to be made such
         investigation of the business, books, records, contracts, employees,
         and properties of it and its Subsidiaries during normal business hours
         and of their respective financial and legal conditions as the other
         Party reasonably requests, provided that such investigation shall be
         reasonably related to the transactions contemplated hereby and shall
         not interfere unreasonably with normal operations. No investigation by
         a Party shall affect the representations and warranties of the other
         Party.

                  (b) Each Party shall, and shall cause its advisers and agents
         to, maintain the confidentiality of all confidential information
         furnished to it by the other Party concerning its and its Subsidiaries'
         businesses, operations, and financial positions and shall not use such
         information for any purpose except in furtherance of the transactions
         contemplated by this Agreement. If this Agreement is terminated prior
         to the Effective Time, each Party shall promptly return or certify the
         destruction of all documents, electronic files and copies thereof, and
         all work papers containing confidential information received from other
         Party.

                  (c) ONSB shall use its commercially reasonable best efforts to
         exercise its rights under confidentiality agreements entered into with
         Persons which were considering an acquisition transaction with ONSB to
         preserve the confidentiality of the information relating to ONSB
         provided to such parties.

                  8.6 PRESS RELEASES. Prior to the Effective Time, ONSB and LSB
shall consult with each other as to the form and substance of any press release
or other public disclosure materially related to this Agreement or any other
transaction contemplated hereby; provided, however, that nothing in this Section
8.6 shall be deemed to prohibit any Party from making any disclosure which its
counsel deems necessary or advisable in order to satisfy such Party's disclosure
obligations imposed by Law.

                  8.7 NO-SHOP COVENANT. Except with respect to this Agreement
and the transactions contemplated hereby, no ONSB Company nor any Affiliate
thereof nor any Representatives thereof retained by any ONSB Company shall
directly or indirectly solicit any Acquisition Proposal by any Person. Except to
the extent necessary to comply with the fiduciary duties of ONSB's Board of
Directors as advised in writing by counsel to such Board of Directors, no ONSB
Company or any Affiliate or Representative thereof shall

                                       37

<PAGE>   43



furnish any non-public information that it is not legally obligated to furnish,
negotiate with respect to, or enter into any Contract with respect to, any
Acquisition Proposal, but ONSB may communicate information about such an
Acquisition Proposal to its shareholders if and to the extent that it is
required to do so in order to comply with its legal obligations as advised in
writing by counsel. ONSB shall promptly notify LSB orally and in writing in the
event that it receives any inquiry or proposal relating to any such transaction.
ONSB shall (i) immediately cease and cause to be terminated as of the date of
this Agreement any existing activities, discussions or negotiations with any
Persons conducted heretofore with respect to any of the foregoing, and (ii)
direct and use its commercially reasonable best efforts to cause all of its
Representatives not to engage in any of the foregoing. The Parties agree that
nothing in this Section 8.7 shall affect ONSB's no-shop obligations and LSB's
right of first refusal and right to a break-up fee set forth in Section 8 of the
Letter of Intent.

                  8.8 ACCOUNTING AND TAX TREATMENT. Each of the Parties
undertakes and agrees to use its commercially reasonable best efforts to cause
the Merger, and to take no action which would cause the Merger not, to qualify
for "pooling-of-interests" accounting treatment consistent with GAAP and the
rules and regulations of the SEC and treatment as a "reorganization" within the
meaning of Section 368(a) of the Internal Revenue Code for federal income tax
purposes.

                  8.9 STATE TAKEOVER LAWS. No ONSB Company shall take any steps
to make the transactions contemplated by this Agreement subject to any Takeover
Law, including Articles 9 and 9A of the NCBCA.

                  8.10 CHARTER PROVISIONS. Each ONSB Company shall take all
necessary action to ensure that the entering into of this Agreement, the Option
Agreement, the Confidentiality Agreement and the Plan of Merger, and the
consummation of the Merger and the other transactions contemplated hereby and
thereby do not and will not result in the grant of any rights to any Person
under the Articles of Incorporation, Bylaws or other governing instruments of
any ONSB Company or restrict or impair the ability of LSB or any of its
Subsidiaries to vote, or otherwise exercise the rights of a shareholder with
respect to, shares of any ONSB Company that may be directly or indirectly
acquired or controlled by LSB.

                  8.11 AGREEMENT OF AFFILIATES. ONSB has disclosed in Section
8.11 of the ONSB Disclosure Memorandum each Person whom it reasonably believes
to be an "affiliate" of ONSB for purposes of Rule 145 under the 1933 Act. ONSB
shall use its commercially reasonable best efforts to cause each such Person to
execute and deliver to LSB not later than thirty (30) days prior to the
Effective Time, an Affiliate Agreement in substantially the form of Exhibit 2
(an "Affiliate Agreement"), providing that such Person will not sell, pledge,
transfer, or otherwise dispose of the shares of ONSB Common Stock held by such
Person, except as contemplated by such Affiliate Agreement or by this Agreement,
and will not sell, pledge, transfer, or otherwise dispose of the shares of LSB
Common Stock to be received by such Person upon consummation of the Merger,
except in compliance with applicable

                                       38

<PAGE>   44



provisions of the 1933 Act and the rules and regulations thereunder and until
such time as financial results covering at least thirty (30) days of combined
operations of LSB and ONSB have been published within the meaning of Section
201.01 of the SEC's Codification of Financial Reporting Policies. In order that
the Merger will qualify for "pooling-of-interests" accounting treatment
consistent with GAAP and the rules and regulations of the SEC, shares of LSB
Common Stock issued to such affiliates of ONSB in exchange for shares of ONSB
Common Stock shall not be transferable until such time as financial results
covering at least thirty (30) days of combined operations of LSB and ONSB have
been published within the meaning of Section 201.01 of the SEC's Codification of
Financial Reporting Policies, regardless of whether each such affiliate has
provided the Affiliate Agreement referred to in this Section 8.11 (and LSB shall
be entitled to place restrictive legends upon certificates for shares of LSB
Common Stock issued to affiliates of ONSB pursuant to this Agreement to enforce
the provisions of this Section 8.11). LSB shall not be required to maintain the
effectiveness of the Registration Statement under the 1933 Act for the purposes
of resale of LSB Common Stock by such affiliates.

                  8.12     EMPLOYEE BENEFITS AND CONTRACTS.

                  (a) Following the Effective Time, LSB shall provide generally
         to officers and employees of the ONSB Companies who at or after the
         Effective Time become employees of a LSB Company (other than Mr. Daves,
         Mr. Marziano and Mr. Darnell who shall have rights to employee benefits
         as provided under their existing agreements), employee benefits under
         employee benefit plans (other than stock option or other plans
         involving the potential issuance of LSB Common Stock, except as set
         forth in this Section 8.12), on terms and conditions substantially
         similar to those currently provided by the LSB Companies to their
         similarly situated officers and employees. For purposes of
         participation and vesting (but not accrual of benefits) under such
         employee benefit plans, (i) service under any qualified defined benefit
         plans of ONSB shall be treated as service under LSB's qualified defined
         benefit plans, (ii) service under any qualified defined contribution
         plans of ONSB shall be treated as service under LSB's qualified defined
         contribution plans, and (iii) service under any other employee benefit
         plans of ONSB shall be treated as service under any similar employee
         benefit plans maintained by LSB. LSB shall cause its, and its
         Subsidiaries', employee benefit plans to waive any pre-existing
         condition limitations covered under the applicable employee benefit
         plans of the ONSB Companies for any employees of the ONSB Companies who
         become or remain employees of any LSB Company. LSB also shall, and
         shall cause its Subsidiaries to, honor all employment, consulting and
         other compensation Contracts disclosed in Section 8.12 of the ONSB
         Disclosure Memorandum between any ONSB Company and any current or
         former director, officer, or employee thereof and all provisions for
         vested benefits or other vested amounts earned or accrued through the
         Effective Time under the ONSB Benefit Plans disclosed in Section 8.12
         of the ONSB Disclosure Memorandum.

                  (b) Each person employed by an ONSB Company on a full-time
         basis at the Effective Time (other than Mr. Daves, Mr. Marziano and Mr.
         Darnell) who, following the Merger and at LSB's sole discretion, is
         terminated by an LSB Company for reasons other than Cause (as defined
         below) within six (6) months following the Effective Time shall be
         entitled to a severance payment by LSB Bank in an amount equal to one
         (1) week's salary or wages for each full year of prior continuous
         service with an ONSB Company, provided that any severance payment shall
         consist of a minimum of two (2) weeks' salary or wages. For purposes of
         this Section, the term "Cause" shall mean (i) failure or refusal of
         employee to comply with duties and responsibilities substantially
         similar to those assigned to the employee immediately prior to the
         Merger, (ii) employee being charged by any duly constituted law
         enforcement agency or authority with a crime involving moral turpitude,
         theft, embezzlement, or fraud, or (iii) employee's excessive use or
         abuse of drugs, alcohol or other toxic substances. To the extent any
         ONSB Company maintains any plan or arrangement for the payment of
         severance or salary continuation benefits to employees, such plan or
         arrangement (except as provided in this Section 8.12(c)) shall be
         terminated at the Effective Time and be of no force and effect
         thereafter.

                  8.13 TAX FREE REORGANIZATION. The Parties agree to use their
commercially reasonable best efforts to obtain a written opinion of Bell, Davis
& Pitt, P.A., in form reasonably satisfactory to such Parties (the "Tax
Opinion"), to the effect that (i) the Merger will constitute a "reorganization"
within the meaning of Section 368(a) of the Internal Revenue Code, (ii) the
exchange in the Merger of ONSB Common Stock for LSB Common Stock will not give
rise to gain or loss to the shareholders of ONSB with respect to such exchange
(except that a shareholder who receives cash hereunder (as a result of the
exercise of dissenters' rights or in lieu of fractional shares) will recognize a
taxable gain up to the extent of any cash received, but will not recognize any
taxable loss), and (iii) each of ONSB, LSB, and LSB Bank will be a party to that
"reorganization" within the meaning of Section 368(b) of the Internal Revenue
Code and none of such parties will recognize gain or loss as a consequence of
the Merger. In rendering such Tax Opinion, counsel shall be entitled to rely
upon representations of officers of ONSB, LSB and LSB Bank reasonably
satisfactory in form and substance to such counsel.

                  8.14 D&O INSURANCE.

                  (a) LSB shall use its commercially reasonable best efforts
         (and ONSB shall cooperate prior to the Effective Time in these efforts)
         to maintain in effect for a period of three (3) years after the
         Effective Time ONSB's existing directors' and officers' liability
         insurance policy (provided that LSB may substitute therefor (i)
         policies of at least the same coverage and amounts containing terms and
         conditions which are substantially no less advantageous or (ii) with
         the consent of ONSB given prior to the Effective Time, any other
         policy) with respect to claims arising from facts or events which
         occurred prior to the Effective Time and covering persons who are

                                       40

<PAGE>   46



         currently covered by such insurance; provided, that LSB shall not be
         obligated to make aggregate premium payments for such three-year period
         in respect of such policy (or coverage replacing such policy) which
         exceed, for the portion related to ONSB's directors and officers, 250%
         of the annual premium payments on ONSB's current policy in effect as of
         the date of this Agreement (the "Maximum Amount"). If the amount of the
         premiums necessary to maintain or procure such insurance coverage
         exceeds the Maximum Amount, LSB shall use its commercially reasonable
         best efforts to maintain the most advantageous policies of directors'
         and officers' liability insurance obtainable for a premium equal to the
         Maximum Amount.

                  (b) If the Surviving Bank or any of its successors or assigns
         shall consolidate with or merge into any other Person and shall not be
         the continuing or surviving Person of such consolidation or merger or
         shall transfer all or substantially all of its assets to any Person,
         then and in each case, proper provision shall be made so that the
         successors and assigns of the Surviving Bank shall assume the
         obligations set forth in this Section 8.14.


                                    ARTICLE 9
                CONDITIONS PRECEDENT TO OBLIGATIONS TO CONSUMMATE

                  9.1 CONDITIONS TO OBLIGATIONS OF EACH PARTY. The respective
obligations of each Party to perform this Agreement and consummate the Merger
and the other transactions contemplated hereby are subject to the satisfaction
of the following conditions, unless waived by both Parties pursuant to Section
11.6 hereof:

                  (a) Shareholder Approval. The shareholders of ONSB and LSB
         shall have approved this Agreement and the Plan of Merger and the
         consummation of the transactions contemplated hereby and thereby,
         including the Merger, as and to the extent required by Law or by the
         provisions of any governing instruments.

                  (b) Regulatory Approvals. All Consents of, filings and
         registrations with, and notifications to, all Regulatory Authorities
         required for consummation of the Merger shall have been obtained or
         made and shall be in full force and effect and all waiting periods
         required by Law, including the HSR Act, shall have expired. No Consent
         obtained from any Regulatory Authority which is necessary to consummate
         the transactions contemplated hereby shall be conditioned or restricted
         in a manner (including requirements relating to the raising of
         additional capital or the disposition of Assets) which in the
         reasonable good faith judgment of the Board of Directors of either
         Party would so materially adversely impact the economic or business
         assumptions of the transactions contemplated by this Agreement that,
         had such condition or requirement been known, such Party would not, in
         its reasonable good faith judgment have entered into this Agreement.

                                       41

<PAGE>   47




                  (c) Consents and Approvals. Each Party shall have obtained any
         and all Consents required for consummation of the Merger (other than
         those referred to in Section 9.1(b) hereof) or for the preventing of
         any Default under any Contract or Permit of such Party which, if not
         obtained or made, is reasonably likely to have, individually or in the
         aggregate, a Material Adverse Effect on such Party.

                  (d) Legal Proceeding. No court or governmental or regulatory
         authority of competent jurisdiction shall have enacted, issued,
         promulgated, enforced or entered any Law or Order (whether temporary,
         preliminary or permanent) or taken any other action which prohibits,
         restricts or makes illegal consummation of the transactions
         contemplated by this Agreement.

                  (e) Registration Statement. The Registration Statement shall
         be effective under the 1933 Act, no stop orders suspending the
         effectiveness of the Registration Statement shall have been issued, no
         action, suit, proceeding or investigation by the SEC to suspend the
         effectiveness thereof shall have been initiated and be continuing, and
         all necessary approvals under state securities Laws or the 1933 Act or
         1934 Act relating to the issuance or trading of the shares of LSB
         Common Stock issuable pursuant to the Merger shall have been received.

                  (f) Nasdaq/NMS Listing. The shares of LSB Common Stock
         issuable pursuant to the Merger shall have been approved for listing on
         the Nasdaq/NMS.

                  (g) Pooling Letters. Each of the Parties shall have received a
         letter, dated as of the Effective Time, in form and substance
         reasonably acceptable to such Party, from Arthur Anderson LLP to the
         effect that the Merger will qualify for "pooling-of-interests"
         accounting treatment under Accounting Principles Board Opinion No. 16
         and consistent with the rules and regulations of the SEC if closed and
         consummated in accordance with this Agreement. Each of the Parties also
         shall have received a letter, dated as of the Effective Time, and in
         form and substance reasonably acceptable to such Party, from Larrowe,
         Cardwell & Company, LC to the effect that such firm is not aware of any
         matters relating to ONSB and its Subsidiaries which would preclude the
         Merger from qualifying for "pooling-of-interests" accounting treatment
         under Accounting Principles Board Opinion No. 16 and consistent with
         the rules and regulations of the SEC.

                  (h) Tax Matters. Each Party shall have received a copy of the
         Tax Opinion referred to in Section 8.13 hereof. In addition, each Party
         shall have delivered to the other Parties a Certificate, dated as of
         the date of the Tax Opinion, signed by its duly authorized officers, to
         the effect that, to the best knowledge and belief of such officers, the
         statement of facts and representations made on behalf of the management
         of such Party, presented to the legal counsel delivering the Tax
         Opinion, were at the date of such presentation, true, correct, and
         complete, and are

                                       42

<PAGE>   48



         on the date of such Certificate, to the extent contemplated by the
         presentation, true, correct, and complete, as though such presentation
         had been made on the date of such Certificate.

                  (i) Plan of Merger; Articles of Merger. Each Party shall have
         received from LSB Bank and ONSB the executed Plan of Merger and the
         executed Articles of Merger.

                  9.2 CONDITIONS TO OBLIGATIONS OF LSB. The obligations of LSB
to perform this Agreement and consummate the Merger and the other transactions
contemplated hereby are subject to the satisfaction of the following conditions,
unless waived by LSB pursuant to Section 11.6(a) hereof:

         Section 9.2(a), the accuracy of the representations and warranties of
         ONSB set forth in this Agreement shall be assessed as of the date of
         this Agreement and as of the Effective Time with the same effect as
         though all such representations and warranties had been made on and as
         of the Effective Time (provided that representations and warranties
         which are confined to a specified date shall speak only as of such
         date). The representations and warranties of ONSB set forth in Sections
         5.3 and 5.7 hereof shall be true and correct (except for inaccuracies
         which are de minimus in amount). The representations and warranties of
         ONSB set forth in Sections 5.17, 5.18, and 5.19 hereof shall be true
         and correct in all material respects. There shall not exist
         inaccuracies in the representations and warranties of ONSB set forth in
         this Agreement (including the representations and warranties set forth
         in Sections 5.3, 5.7, 5.17, 5.18, and 5.19) such that the aggregate
         effect of such inaccuracies has, or is reasonably likely to have, a
         Material Adverse Effect on ONSB; provided that, for purposes of this
         sentence only, those representations and warranties which are qualified
         by references to "material" or "Material Adverse Effect" shall be
         deemed not to include such qualifications.

                  (b) Performance of Agreements and Covenants. Each and all of
         the agreements and covenants of ONSB to be performed and complied with
         pursuant to this Agreement and the other agreements contemplated hereby

         certified copies of resolutions duly adopted by ONSB's Board of
         Directors and shareholders evidencing the taking of all corporate
         action necessary to authorize the execution, delivery and performance

                                       43

         the Plan of Merger, and the consummation of the transactions
         contemplated hereby and thereby, all in such reasonable detail as LSB

                  (d) Opinion of Counsel. LSB shall have received a written
         opinion of Bell, Davis & Pitt, P.A., counsel to ONSB, dated as of the

                  (e) Fairness Opinion. LSB shall have received from The Carson
         Medlin Company a letter, dated not more than five (5) business days
         prior to the date of the LSB Proxy Statement, to the effect that, in

         of the LSB Proxy Statement, and (iii) the Effective Time, with respect
         to certain financial information regarding ONSB, in form and substance
         reasonably satisfactory to LSB, which letters shall be based upon
         customary specified procedures undertaken by such firm in accordance
         with Statement of Auditing Standard No. 72.

                  (g) Affiliate Agreements. LSB shall have received from each
         affiliate of ONSB an executed Affiliate Agreement referred to in
         Section 8.11 hereof, to the extent necessary to assure in the
         reasonable judgment of LSB that the transactions contemplated hereby
         will qualify for "pooling-of-interests" accounting treatment consistent

         dispute referred to in Section 5.14 of the ONSB Disclosure Memorandum
         in a manner (including, without limitation, on terms and conditions, if
         resolved) reasonably satisfactory to LSB.

                  9.3 CONDITIONS TO OBLIGATIONS OF ONSB. The obligations of ONSB
to perform this Agreement and consummate the Merger and the other transactions
contemplated hereby are subject to the satisfaction or the following conditions,
unless waived by ONSB pursuant to Section 11.6(b) hereof:

<PAGE>   50



                  (a) Representations and Warranties. For purposes of this
         Section 9.3(a), the accuracy of the representations and warranties of
         LSB set forth in this Agreement shall be assessed as of the date of
         this Agreement and as of the Effective Time with the same effect as
         though all such representations and warranties had been made on and as
         of the Effective Time (provided that representations and warranties
         which are confined to a specified date shall speak only as of such
         date). The representations and warranties of LSB set forth in Section
         6.3 hereof shall be true and correct (except for inaccuracies which are
         de minimus in amount). The representations and warranties of LSB set
         forth in Section 6.11 hereof shall be true and correct in all material
         respects. There shall not exist inaccuracies in the representations and
         warranties of LSB set forth in this Agreement (including the
         representations and warranties set forth in Sections 6.3 and 6.11) such
         that the aggregate effect of such inaccuracies has, or is reasonably
         likely to have, a Material Adverse Effect on LSB; provided that, for
         purposes of this sentence only, those representations and warranties
         which are qualified by references to "material" or "Material Adverse
         Effect" shall be deemed not to include such qualifications.

                  (b) Performance of Agreements and Covenants. Each and all of
         the agreements and covenants of LSB to be performed and complied with
         pursuant to this Agreement and the other agreements contemplated hereby
         prior to the Effective Time shall have been duly performed and complied
         with in all material respects.

         certificate, dated as of the Effective Time and signed on its behalf by
         its Chairman of the Board, President and Chief Executive Officer, to

         9.3(a) and 9.3(b) hereof have been satisfied, and (ii) certified copies
         of resolutions duly adopted by LSB's Board of Directors and the

         forth in Section 9.2(a) hereof in the case of ONSB and Section 9.3(a)
         in the case of LSB or in material breach of any covenant or other
         agreement contained in this Agreement) in the event of an inaccuracy of
         any representation or warranty of the other Party contained in this
         Agreement which cannot be or has not been cured within thirty (30) days
         after receipt of written notice by the breaching Party of such
         inaccuracy and which inaccuracy would provide the terminating Party the
         ability to refuse to consummate the Merger under the applicable
         standard set forth in Section 9.2(a) hereof in the case of ONSB and
         Section 9.3(a) hereof in the case of LSB; or

                  (c) By the Board of Directors of either Party (provided that
         the terminating Party is not then in breach of any representation or
         warranty contained in this Agreement under the applicable standard set
         forth in Section 9.2(a) hereof in the case of ONSB and Section 9.3(a)
         in the case of LSB or in material breach of any covenant or other

         days after the receipt of written notice by the breaching Party of such
         breach; or

                  (d) By the Board of Directors of either Party in the event (i)
         any Consent of any Regulatory Authority required for consummation of
         the Merger and the other transactions contemplated hereby shall have
         been denied by final nonappealable action of such authority or if any
         action taken by such authority is not appealed within the time limit
         for appeal, or (ii) the shareholders of ONSB or LSB fail to vote their
         approval of this Agreement and the Plan of Merger and the transactions

                  (e) By the Board of Directors of either Party in the event
         that the Merger shall not have been consummated by September 30, 1997,
         if the failure to consummate the transactions contemplated hereby on or
         before such date is not caused by any breach of this Agreement by the
         Party electing to terminate pursuant to this Section 10.1(e); or

                  (f) By the Board of Directors of either Party (provided that

         in the case of LSB or in material breach of any covenant or other
         agreement contained in this Agreement) in the event that any of the
         conditions precedent to the obligations of such Party to consummate the
         Merger (other than as contemplated by Section 10.1(d) hereof) cannot be
         satisfied or fulfilled by the date specified in Section 10.1(e) hereof;
         or

                  (h) By the Board of Directors of LSB, at any time prior to the
         90th day after the date of this Agreement, in the event that the review
         of the Assets, business, financial condition, results of operations,
         and prospects of ONSB undertaken by LSB and its Representatives during
         such time period or any of the disclosures contained in the ONSB
         Disclosure Memorandum causes the Board of Directors of LSB to
         determine, in its reasonable good faith judgment, that a fact or
         circumstance exists or is likely to exist or result which materially
         and adversely impacts the economic benefits taken as whole to LSB of
         the transactions contemplated by this Agreement so as to render
         inadvisable the consummation of the Merger; or

                  (i) By the Board of Directors of either Party in the event the
         Average LSB Closing Price is either below $15.00 or above $24.00,
         provided that such termination must occur during the 7-day period
         commencing after the Pricing Period by the terminating Party giving
         written notice of termination to the other Party.

                  10.2 EFFECT OF TERMINATION. In the event of the termination of
this Agreement and abandonment of the Merger pursuant to Section 10.1 hereof,
this Agreement shall become void and have no effect, except that (i) the
provisions of this Section 10.2 and Article 11 and Section 8.5(b) hereof shall
survive any such termination and abandonment, and (ii) a termination pursuant to
Sections 10.1(b), 10.1(c), 10.1(f) or 10.1(g) hereof shall not relieve the
breaching Party from liability for an uncured willful breach of a
representation, warranty, covenant, or agreement giving rise to such
termination. The
