ITEM 1.     BUSINESS

            Southern Arizona Bancorp, Inc. (the "Company") is an Arizona
corporation incorporated in 1985 and is registered as a bank holding company
under the Bank Holding Company Act of 1956. Its sole subsidiary is Southern
Arizona Bank (the "Bank"). The Bank provides a wide variety of general
commercial and retail banking services, which include lending, depository, and
related financial services to individuals, businesses, governmental units, and
financial institutions in Arizona. The Bank is a state banking association
chartered under the laws of the State of Arizona. It commenced operations in
Yuma, Arizona on August 2, 1982. At December 31, 1995, the Bank had assets of
$127 million, net loans of $85 million, and deposits of $115 million. The Bank
operates five banking facilities in Yuma County, Arizona and currently has 87
employees.

            Commercial Banking and Related Services. The Bank is engaged in the
financing of commerce and industry by providing credit facilities and related
services for business of all sizes. The Bank offers all forms of commercial
lending, including lines of credit, revolving credits, term loans, accounts
receivable financing, residential mortgage lending, and commercial real estate
and other forms of secured financing.

            Personal Banking Services. A wide range of personal banking services
is provided to individuals at each of the Bank's branch offices. Among the
services provided are interest-bearing and non-interest-bearing checking
accounts, savings and time accounts, installment and other personal loans, home
equity loans, automobile and other consumer financing, safe deposit services,
and residential mortgage loans. The Bank is a member of regional, national, and
international automated teller machine ("ATM") networks, which permit customers
to access their accounts at thousands of electronic terminals in the Southwest
region, as well as nationally and internationally.

            Competition. The Company and the Bank operate in a competitive
environment in Arizona that has intensified in the past few years. Profit
margins in the traditional banking business of lending and deposit gathering
have declined as deregulation, both in the United States and foreign countries,
has allowed foreign banks and non-banking institutions to offer alternative
services to many of the Bank's customers.

            The principal competitive factors among financial institutions can
be classified into two categories: pricing and services. Interest rates on
deposits, especially in the area of time deposits, and interest rates and fees
charged to customers on loans are very competitive. From a service standpoint,
financial institutions compete against each other in convenience of location,
types of services, service costs, and banking hours. The Bank is generally
competitive with competing financial institutions in its primary service areas
with respect to interest rates paid on time and savings deposits, charges on
deposit accounts, and interest rates and fees charged on loans.

            The Company and the Bank compete with other major commercial banks
based or conducting business in Arizona. In addition, the Company and the Bank
encounter competition from diversified financial institutions, offices of
foreign banks offering domestic services, savings banks, savings and loan
associations, credit unions, money market and other mutual funds, mortgage
companies, leasing companies, finance companies, investment banking companies,
merchant banks, and a variety of other financial services and advisory
companies.

            The Company and the Bank consider all banks in its market area to be
competitors; however, of the seven (7) banks (including the Bank) in Yuma,
management considers the large banks to be the major competitors such as The
Bank of America, Banc One, Wells Fargo, and Norwest (Arizona).

            In January 1996, the Company entered into an Agreement and Plan of
Reorganization with Zions Bancorporation, a Utah corporation ("Zions"), the
Bank, and National Bank of Arizona, a national banking association ("NBA"),
which provided for the Company to merge with and into Zions with Zions being the
surviving corporation and immediately thereafter for the Bank to merge with and
into NBA with NBA being the surviving corporation (the "Reorganization"). See
"Security Ownership of Certain Beneficial Owners and Management Changes in
Control" for additional information concerning the Reorganization.

            See "Financial Information" and "Consolidated Financial Statements"
for additional information concerning the business of the Company and the Bank.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE THREE-YEAR PERIOD ENDED DECEMBER 31, 1995

            The following analysis of the Company's financial condition and
results of operations as of and for the three year period ended December 31,
1995, should be read in conjunction with the Consolidated Financial Statements
of the Company.

OVERVIEW

            The Company does not engage in any substantial business activity
other than as a bank holding company that holds all of the issued and
outstanding stock of the Bank, its principal asset. Unless otherwise noted, the
following discussion relates to the Company and the Bank on a consolidated
basis.

RESULTS OF OPERATIONS

            Net Income

            Net income for 1995 was $1,999,007, increasing $366,793, or 22.5%,
from 1994. This increase was primarily attributable to growth in the Company's
assets, which resulted in an increase in net interest income of $992,387.

            Net income for 1994 was $1,632,214 compared to $1,291,151 in 1993.
The 1994 increase of $341,063, or 26.4%, was primarily attributable to growth in
the Company's assets as well as a decrease in the Company's provision for loan
losses, which resulted from improvement in the quality of the Company's loan
portfolio.

            Net-Interest Income

            Net interest income, the difference between interest earned on loans
and investments and interest paid on deposits and debt, is the principal
component of the Company's earnings.

            During 1995, net interest income was $7,041,643, increasing
$992,387, or 16.4%, from 1994. This increase was primarily attributable to
growth in the Company's earning assets as well as the utilization of pricing
strategies aimed at maintaining an appropriate net interest spread. Average
interest-earning assets of the Company were $105,018,000 during 1995, an
increase of 14.7% or $13,443,000 from $91,575,000 in 1994.

            During 1994, net interest income was $6,049,256 compared to
$5,162,110 in 1993. The 1994 increase of $887,146, or 17.2%, was primarily
attributable to growth in the Company's earning assets. Average interest-earning
assets of the Company were $91,575,000 during 1994, an increase of $12,133,000,
or 15.3%, from $79,442,000 in 1993.

            Non-Interest Income

            During 1995, non-interest income was $1,280,584, an increase of 4.9%
from $1,220,741 in 1994. This increase was primarily attributable to an increase
in customer service fees of $136,564 resulting from increased volume, pricing of
the Bank's services, and fee income from additional checking accounts opened and
maintained at the Bank.

            Non-interest income for 1994 had decreased $172,790, or 12.4%, from
the non-interest income of $1,393,531 in 1993. This decrease was primarily
attributable to exceptional gains on the sale of loans and investments realized
in 1993. In 1993, due to favorable interest rates and the Company's focus on
optimum asset allocation, the Company realized gains on the sale of mortgage
loans and investment securities of $882,406 as compared to $513,741 in 1994.

            Non-Interest Expense

            Non-interest expense was $4,699,650 for the year ended December 31,
1995 compared to $4,288,619 and $3,827,811 for the years ended December 31, 1994
and December 31, 1993, respectively. Historically, the Company's non-interest
expense has increased relatively proportionately to the growth of the Company's
assets. The increases in non-interest expense for the years 1995 and 1994 have
resulted from the Company's expansion of staff, premises, and other resources to
support the economic progress of the Company.

FINANCIAL CONDITION

            Assets

            At December 31, 1995, total assets were $127,417,893 as compared to
$101,254,421 on December 31, 1994, representing an increase of 26%. This
increase was primarily attributable to the Bank's implementation of an
aggressive strategy to acquire large, commercial deposits.

            Total assets for 1994 had increased 11% from total assets of
$91,225,493 in 1993. This increase was primarily attributable to an increase in
net loans of $16,013,363 and branch remodelings that facilitated customer
service.

            Investment

            Investment securities held by the Company were $1,886,870 at
December 31, 1995 compared to $7,672,189 at December 31, 1994. This decrease was
primarily attributable to a reallocation of investment securities to Fed Funds.
In addition, the Company had short term investments in time deposits with other
banks and Fed Funds sold of $25,788,000. The Company's portfolio mix is
structured to meet the liquidity needs of the Bank brought about by loan demand
and seasonal swings in the deposit base.

            Investment securities held by the Company as of December 31, 1994
decreased 43.4% from investment securities held by the Company of $13,551,719 as
of December 31, 1993. This decrease was primarily attributable to strong loan
demand for the year 1994, which was partially funded by matured securities.

            Loans

            Loan growth has been somewhat lower than asset growth in order to
maintain acceptable liquidity and to reduce the Company's loan/deposit ratio to
between 75 and 80%.

            The Company's loan portfolio grew in 1995 to $85,584,967, increasing
$4,895,982, or 6.1%, from 1994. The Company's loan portfolio also grew in 1994
to $80,688,985, increasing $15,541,589, or 23.9%, from 1993. This growth in the
Company's loan portfolio in both 1995 and 1994 was primarily attributable to the
Company's emphasis on competitive pricing, favorable interest rates, and
strength in the local economy.

            The Company's loan portfolio mix has not varied significantly over
the last three years. Commercial loans comprised 73.7% of the Company's loan
portfolio in 1995, decreasing from 78.2% and 77.0% of the Company's loan
portfolio in 1994 and 1993, respectively. Real Estate loans comprised 11.6% of
the Company's loan portfolio in 1995, compared to 10.2% and 11.5% of the
Company's loan portfolio in 1994 and 1993, respectively. Installment and other
loans comprised primarily of automobile loans and home improvement loans, made
up 14.7% of the Company's loan portfolio in 1995, compared to 11.6% and 10.3% of
the Company's loan portfolio in 1994 and 1993, respectively. The 1995 increase
in installment loans was primarily attributable to the Company's emphasis on
mobile home lending and the Company's management's desire for greater liquidity.
The Bank does not have foreign or energy loans.

            Loans that were 90-days or more past due or nonaccrual constituted
 .01% of the Company's net loan portfolio as of December 31, 1995, compared to
 .24% and .02% of the Company's loan portfolio at December 31,

   6
1994 and December 31, 1993, respectively. The 1995 decrease was primarily
attributable to the Company's management's desire to reduce the delinquency
ratio of the Company loan portfolio.

            Allowance for Loan Losses

            The Company's allowance for loan losses at December 31, 1995, was
$2,466,513 compared to $2,393,242 and $1,990,428 at December 31, 1994 and
December 31, 1993, respectively. The allowance for loan losses as a percent of
gross loans was 2.78%, 2.86%, and 2.94% for the years 1995, 1994, and 1993,
respectively.

            Amounts charged-off to the allowance for loan losses in 1995 were
$349,214, compared to $45,294 and $109,455 in 1994 and 1993, respectively.
Factors such as economic conditions and problems with individual borrowers has
affected amounts charged-off to the allowance for loan losses over the last
three years. However, as a result of prudent lending policies and periodic
review, the Company has experienced minimal loan losses.

DEPOSITS

            Typically, the Company experiences a large increase in deposits at
year end due to the seasonal local economy, which is not accompanied by a large
increase in loan demand.

            The Company's deposits at December 31, 1995 were $114,761,830,
increasing $23,556,446, or 25.8%, from 1994. This increase was primarily
attributable to the Company's focus on acquiring larger, commercial depositors.
Additionally, the merger and closing of several competitors contributed to the
growth in the Company's deposits.

            The Company's deposits at December 31, 1994 were $91,205,384,
increasing $8,889,090, or 10.8%, from 1993. This increase was primarily
attributable to the growing local economy and the expansion of two branch
facilities.

LIQUIDITY

            The Company has maintained liquidity and continues to maintain
adequate liquidity. Although the Company's loan/deposit ratio was 85.10% in
1995, the Company has reduced its loan growth to lower its loan/deposit ratio to
between 75-80% and, as a result, has adequately maintained its liquidity.
Additionally, the Company had $25,194,000 in Fed Funds as of December 31, 1995
and currently has substantial unused borrowing lines available through
correspondent banks. These borrowing lines are available to the Company in the
event that the seasonal swing in deposits is greater than anticipated.

            One source of funds for the Company is dividends received from the
Bank. The amount of dividends that a bank may pay in any year is subject to
certain regulatory restrictions. Generally, dividends paid in a given year by a
bank are limited to its net profit, as defined by regulatory agencies, for the
year combined with its retained net income for the preceding two-years. However,
a bank may not pay dividends if such payments would leave the bank inadequately
capitalized. Hence, the ability of the Bank to pay dividends will depend on its
future net income and capital requirements.

CAPITAL RESOURCES

            In 1993, the Company issued $2,500,000 principal amount of 8.75%
Senior Notes (the "Notes"). The proceeds of such issuance were used as capital
for the continued expansion of the Bank. The Company intends to prepay the
Senior Notes on or about May 27, 1996 with the proceeds of a loan from Zions.
Such loan provides for the Company to borrow from Zions that amount which will
enable the company to prepay the Notes, including the premium payable resulting
from the prepayment of the Notes. Quantitative measures established by
regulation to ensure capital adequacy require the Bank to maintain certain
minimum amounts and ratios of total and Tier I capital (as defined by the
Federal Deposit Insurance Corporation) to risk-weighted assets, and of Tier I
capital to


                                        6
   7
average assets. As of December 31, 1995, management believes that the Bank has
met all capital adequacy requirements to which it is subject.

EFFECTS OF INFLATION

            The net income of the Company depends to a great extent upon its net
interest margin. Net interest margin is the difference between the income the
Company receives from its loans, securities, and other interest earning assets
and the interest it pays on its deposits and other interest paying liabilities.
Inflation and interest rates are highly sensitive to many factors beyond the
control of the Company, including general economic conditions and policies of
various governmental and regulatory authorities. The Company attempts to limit
adverse exposure to inflation and interest rate changes by properly matching
rate sensitive assets and liabilities.

CHANGES IN CONTROL

            At a Special Meeting on May 22, 1996, the Company's shareholders 
voted to approve and adopt the Agreement and Plan of Reorganization dated as of
January 17, 1996 (the "Plan of Reorganization"), between the Company, Zions
Bancorporation, a Utah corporation ("Zions"), the Bank, and National Bank of
Arizona ("NBA"), a wholly-owned subsidiary of Zions. The Plan of Reorganization
provides for the merger of the Company with and into Zions with Zions being the
surviving corporation and immediately thereafter for the merger of the Bank
with and into NBA with NBA being the surviving corporation (the
"Reorganization"). The Plan of Reorganization provides that upon consummation
of the latter merger, NBA will


                                        9
   10
continue as a direct wholly-owned subsidiary of Zions (except for directors'
qualifying shares). Shareholder approval for the Reorganization requires the
affirmative vote of at least two-thirds of the holders of the Company's Common
Stock and the affirmative vote of the holders of at least two-thirds of the
outstanding shares of the Company's Common Stock. Each of the Company's
directors has agreed to vote the shares owned by such director in favor or the
Reorganization. Zions is a bank holding company incorporated in Utah. The
principal subsidiaries of Zions are Zions First National Bank with 94 offices
located throughout the state of Utah and one foreign office, Nevada State Bank
with 25 offices in Nevada, and NBA with eleven offices in Arizona.

            In the event the Reorganization is consummated, the shareholders of
Southern Arizona (except dissenting shareholders) will become shareholders of
Zions. The Plan of Reorganization provides that the approximately 1,266,362
outstanding shares of Southern Arizona Common Stock (other than shares subject
to dissenters' rights) will be converted into the right to receive that number
of shares of Zions Common Stock calculated by dividing the Benchmark Price of
$25,330,000 plus certain accretions determined on the Effective Date of the
Reorganization by the Average Closing Price of Zions Common Stock (as defined in
the Plan of Reorganization). If the Unadjusted Average Price (as defined in the
Plan of Reorganization) is less than $59.00, the shareholders of Southern
Arizona will also be entitled to a cash payment.

ITEM 6.     EXECUTIVE COMPENSATION

            The following table sets forth the compensation received by the
Company's Chief Executive Officer for the last three fiscal years ending
December 31, 1995. No other executive officers of the Company received
compensation in excess of $100,000 during the Company's last three fiscal years,
however, the following table includes an executive officer of the Bank who
received compensation in excess of $100,000 during the Bank's last three fiscal
years. The Company believes that it is appropriate to include such executive
officer because he has performed policy making functions for the Company.

        401(k) Plan (as described herein) and the Bank's Employee Stock
        Ownership Plan (as described herein) earned during the year shown. In
        addition, amounts shown for Mr. Byrd include directors fees and term
        life insurance premiums paid by the Company for the benefit of Mr. Byrd.
        The amounts shown for Mr. Byrd do not include a one-time premium of
        $384,471.55 paid for a retirement policy for Mr. Byrd, which will be
        payable to Mr. Byrd in annual installments upon his retirement from the
        Company and the Bank. Such policy was established and the one-time
        premium was paid in 1987.

401(K) PROFIT SHARING PLAN

            In 1986, the Bank adopted a profit sharing plan pursuant to Section
401(k) (the "401(k) Plan") of the Internal Revenue Code of 1986, as amended (the
"Code"). All full-time and part-time employees of the Bank who have reached 21
years of age and have completed one Year of Service (as defined in the 401(k)
Plan) to the Bank are eligible to participate in the 401(k) Plan.

            Pursuant to the 401(k) Plan, all eligible employees may make
elective pre-tax contributions through payroll deductions, which may not exceed
those limitations imposed by law. The 401(k) Plan provides that such
contributions shall vest immediately. The 401(k) Plan further provides that the
Bank shall make an annual contribution equal to one-fourth of one percent of a
participant's compensation if such participant completes a Year of Service in
each Plan Year. In addition, the Bank may make discretionary contributions to
the 401(k) Plan in such amounts as may be determined by the Company. The 401(k)
Plan's Trustees, which consist of four members of the Board of Directors of the
Company, have been designated to hold and invest the Plan's assets for the
benefit of the 401(k) Plan's participants. Contributions to the 401(k) Plan
totalled approximately $89,000, $83,000, and $71,000 for the years ended
December 31, 1995, 1994, and 1993, respectively.

EMPLOYEE STOCK OWNERSHIP PLAN

            The Bank has sponsored an Employee Stock Ownership Plan (the "Plan")
since 1986. All full-time and part-time employees of the Bank who have reached
21 years of age and have completed one Year of Service (as defined in the Plan)
for the Bank are eligible to participate in the Plan.

            The Bank makes voluntary, discretionary contributions to the Plan
each year. The Plan's participants are 100% vested after five Years of Service
to the Bank. Common Stock of the Company held by the Plan is voted by the Plan's
Trustees, which consist of three members of the Board of Directors of the
Company. Contributions to the Plan totaled approximately $54,000, $123,000, and
$128,000 for the years ended December 31, 1995, 1994, and 1993, respectively.

ITEM 7.     CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

            Directors and officers of the Company, members of their immediate
families, and certain affiliates were customers of, and have had transactions
with, the Bank in the ordinary course of business. Similar transactions in the
ordinary course of business may be expected to take place in the future.

            All loans to executive officers and directors and members of their
immediate families and certain affiliates were made on substantially the same
terms, including interest rates and collateral, as those prevailing at the time
for comparable transactions with other persons and do not involve more than
nominal risk of collectibility or present other unfavorable features. Of the
loans outstanding at December 31, 1995, none were contractually past due 90 days
or more as to principal or interest and none were classified as nonaccrual,
restructured, or potential problem loans.

            All ongoing and future transactions with affiliates of the Company
will be on terms no less favorable than could be obtained from unaffiliated
parties. All future loans from the Bank to Company officials, affiliates, and/or
shareholders will be approved by a majority of the disinterested directors of
the Company.

            In connection with the Bank's purchase of the land and building at
which the San Luis branch currently operates, the Bank entered into a promissory
note for the sum of $480,000 (the "Promissory Note") in which Charles N.
Urtuzuastegui, as Trustee of the Charles N. Urtuzuastegui and Josephine O.
Urtuzuastegui Trust dated February 22, 1972, has a one-third interest. Mr.
Urtuzuastegui is currently a Director of the Company and the Bank. The principal
of the Promissory Note is payable in annual installments of $120,000 or more.
The interest on the Promissory Note is payable annually and is calculated on the
National Prime Rate on each anniversary date of the Promissory Note.

            In connection with the Plan of Reorganization, all of the Company's
shareholder-directors, whose common shareholdings aggregate 24.5% of the
outstanding Common Stock of the Company and who represent approximately 2.4% of
the Company's shareholders of record, have entered into agreements with Zions
under which they have agreed, in their capacity as shareholders, to vote their
shares in favor of the Plan of Reorganization and to support the Plan of
Reorganization and to recommend its adoption by the other shareholders of the
Company. The shareholder-directors have also agreed in their capacity as
directors, until the earlier of the consummation of the Reorganization or the
termination of the Plan of Reorganization, to refrain from soliciting or,
subject to their fiduciary duties to shareholders and to Section 7.8 of the Plan
of Reorganization, negotiating or accepting any offer of merger, consolidation,
or acquisition of any of the shares or substantially all of the assets of the
Company or the Bank. See "Security Ownership of Certain Beneficial Owners and
Management-Changes in Control" for additional information concerning the Plan of
Reorganization.

            The Plan of Reorganization provides that after the Reorganization
becomes effective, NBA will employ John E. Byrd, currently president and chief
executive officer of the Company and the Bank, pursuant to a three-year
agreement as an executive vice president of NBA. The agreement provides that Mr.
Byrd will receive an initial annual salary substantially the same as his current
annual salary with the Company, will be considered annually for a discretionary
bonus, based upon the financial performance of NBA and upon individual
performance factors (the


                                       13
   14
target level for the bonus being 25% - 35% of his then current salary), and will
be entitled to other benefits normally afforded executive employees, including
participation in employee benefit and stock option plans, an automobile
allowance, country club membership, retirement and life insurance policies, and
consideration for periodic raises or bonuses, based upon performance and
responsibility. NBA will also continue to maintain a term life insurance policy
on the life of Mr. Byrd and will pay all the premiums therefor. The policy will
be owned by Mr. Byrd and will provide for the payment of death benefits to his
estate.

            The employment agreement provides for severance benefits for Mr.
Byrd upon the termination of his employment agreement for reasons other than his
death or disability or "for cause" (as defined in his employment agreement). In
the event of termination for reasons other than set forth in the preceding
sentence, Mr. Byrd shall receive (i) salary payable (as defined in the
employment agreement) for a period commencing on the date immediately following
the termination date and ending upon the third anniversary of the effective date
of the employment agreement and (ii) such benefits as Mr. Byrd has accrued under
NBA's Value Sharing Plan, Incentive Stock Option Plan and employee benefit
plans, reimbursement for expenses accrued as of the date of termination of his
employment, and the right to receive the cash equivalent of paid annual leave
and sick leave accrued as of the date of termination of his employment.

            Under his employment agreement, Mr. Byrd has agreed that he will not
for a period of five years from the effective date of the employment agreement
(i) engage in the banking business within Yuma County, Arizona other than on
behalf of NBA or affiliated companies, (ii) own or operate any entity engaged in
the banking business within Yuma County, Arizona other than NBA or affiliated
companies, or (iii) solicit or intentionally cause an officer, director or
employee of NBA to engage in the banking business or own or operate an entity
engaged in the banking business in Yuma County, Arizona. In consideration of
such five-year covenant not to compete, Mr. Byrd will receive a one-time cash
payment of $250,000.

ITEM 9.     MARKET PRICE OF AND DIVIDENDS ON THE REGISTRANT'S COMMON EQUITY AND
            RELATED STOCKHOLDER MATTERS

            The Company's Common Stock is not listed with a national securities
exchange or quoted on any automated quotation system. No established public
trading market for the Company's Common Stock presently exists and the private
market that has existed is thin and not necessarily indicative of the value of
the Company's Common Stock. There were no trades in the Company's Common Stock
in the fourth quarter of 1995 and the first quarter of 1996 and one trade since
the date of the public announcement of the Plan of Reorganization on January 17,
1996. The following table sets forth the high and low prices for the Company's
Common Stock during the calendar quarters shown below, through May 8, 1996, of
which the Company is aware, and the cash dividends per share declared on the
Company's Common Stock for such periods.

            Based upon information available to the management of the Company,
it appears that during the years ended December 31, 1994 and 1995, a total of
159,869 shares and 169,424 shares, respectively, of the Company's Common Stock
were traded (some of which may not have effected changes in the beneficial
ownership of the shares transferred). Additionally, a total of 105 shares of the
Company's Common Stock were traded since January 1, 1996. The foregoing table
may not accurately reflect the full trading range of the Company's Common Stock
during the periods indicated because other transactions may have occurred during
such periods, the terms of which were not conveyed to management. Additionally,
the Company's books and records do not reflect trading prices. Other than with
respect to trades involving officers and directors and trades for which
management may have received information relating to prices, the Company has no
mechanism by which to reconstruct information relating to the per share market
price at which its shares have historically traded.

            None of the Company's Common Stock (i) is subject to outstanding
options or warrants to purchase nor are there any securities convertible into
the Company's Common Stock, (ii) is subject to sale pursuant to Rule 144 under
the Securities Act nor has the Company agreed to register any shares of its
Common Stock under the Securities Act for sale by its security-holders, (iii) is
being or is proposed to be publicly offered by the Company. The holders of the
Company's Common Stock are entitled to receive dividends when, as, and if
declared by the Board of Directors of the Company out of funds legally available
therefor. The Company's ability to pay dividends is governed by Arizona law.
Generally, Arizona law prohibits corporations from paying dividends when after
giving the dividend effect, the corporation would not be able to pay its debts
as they become due in the usual course of business or the corporation's total
assets would be less than the sum of its total liabilities plus the amount that
would be needed if the corporation were to be dissolved at the time of the
distribution to satisfy the preferential rights on dissolution of shareholders
whose preferential rights are superior to those receiving the distribution. The
Company's articles provide that the Company's Board of Directors may, from time
to time, distribute dividends out of the capital surplus of the Company.

            The Bank is subject to certain limitations on the amount of cash
dividends that it can pay. Arizona law allows the board of directors of a bank
to declare dividends as permitted by the laws governing Arizona corporations,
except that dividends payable other than in the bank's own stock may be paid out
of capital surplus only with the approval of the Arizona Superintendent of
Banks. Additionally, the prior approval of the Board of Governors of the Federal
Reserve System (herein, the "Board") is required if the total of all cash
dividends declared by a state-chartered member bank, such as the Bank, in any
calendar year will exceed the total of such bank's net profits (as defined by
statute) for that year combined with its retained net profits for the preceding
two calendar


                                       15
   16
years less any required transfers to surplus. In addition, the Board is
authorized to determine under certain circumstances relating to the financial
condition of a state-chartered member bank that the payment of dividends would
be an unsafe and unsound practice and to prohibit payment thereof.

            Under FDICIA, all insured banks are generally prohibited from making
any capital distributions and from paying management fees to persons having
control of the bank where such payments would cause the bank to be
undercapitalized. Holding companies of undercapitalized banks may be required to
obtain the approval of the Federal Reserve Board before making capital
distributions to their shareholders.

            On May 17, 1996, the Company had approximately 500 shareholders,
based upon the number of shareholders of record. At such date, 1,266,362 shares
of the Company's Common Stock were outstanding.

ITEM 10.    RECENT SALES OF UNREGISTERED SECURITIES

            On June 11, 1993, the Company offered for sale $2,500,000 principal
amount of 8.75% Senior Notes (the "Notes") payable on July 1, 2000. The Company
sold the Notes for cash through its registered broker, Peacock, Hislop, Staley &
Given, Inc., who solicited the Notes on a "best efforts" basis. The Notes were
offered for sale by the Company in reliance upon an exemption from registration
provided by Section 3(a)(11) of the Securities Act of 1933, as amended, and
pursuant to registration in the State of Arizona only. Sales of the Notes were
made only to qualified prospective investors residing in the State of Arizona.
The Company intends to prepay the Notes on or about May 27, 1996 with the
proceeds of a loan from Zions Bancorporation.

ITEM 11.    DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED

            The Company's authorized capital stock consists of 2,000,000 shares
of Common Stock, no par value ("Common Stock"). Prior to the filing of this Form
10, there were outstanding 1,266,362 shares of Common Stock. All of the
currently outstanding shares of Common Stock are validly issued, fully paid, and
nonassessable. At April 17, 1996, there were approximately 500 shareholders of
record of the Company's Common Stock.

            The holders of Common Stock are generally entitled to one vote for
each share on all matters submitted to a vote of shareholders. In elections of
directors, Arizona law requires cumulative voting, which means that each
shareholder may cast the number of votes as is equal to the number of shares
held of record, multiplied by the number of directors to be elected. Each
shareholder may cast the whole number of votes for one candidate or distribute
such votes among two or more candidates. The Company's Articles of Incorporation
require the affirmative vote of at least two-thirds of the holders of Common
Stock and the affirmative vote of the holders of at least two-thirds of the
outstanding shares of Common Stock for shareholder approval of a merger,
consolidation or sale of substantially all of the assets of the Company. In
addition, the Company's Articles of Incorporation provide that shareholder
approval for an amendment to the Company's Articles of Incorporation requires
the affirmative vote of three-fourths of the holders of Common Stock and
shareholder approval for an increase in the maximum number of directors requires
a vote of four-fifths of the holders of Common Stock.

            The holders of Common Stock are entitled to receive dividends, if
any, as may be declared by the Company's Board of Directors from time to time
out of legally available funds. See "Market Price of and Dividends on the
Registrant's Common Equity and Related Stockholder Matters" for additional
information concerning dividends of the Company.

            Upon liquidation, dissolution, or winding up of the Company, the
holders of Common Stock will be entitled to share ratably in all assets of the
Company that are legally available for distribution, after payment of all debts
and other liabilities of the Company. The holders of Common Stock have no
preemptive, subscription, redemption, or conversion rights.

            Although the Company currently does not have any restrictions on the
alienability of Common Stock, the Company's Articles of Incorporation provide
that the Company has the right to impose restrictions on the


                                       16
   17
transfer of Common Stock provided that such restrictions, or notice of such
restrictions, shall be set forth on the Common Stock certificates representing
such shares of stock.

ITEM 12.    INDEMNIFICATION OF DIRECTORS AND OFFICERS

        The Arizona Business Corporation Act (the "Business Corporation Act")
provides that the Company's Articles of Incorporation may eliminate or limit the
liability of directors to the company or its shareholders for money damages for
any action taken or any failure to take any action as a director, except
liability for (a) the amount of a financial benefit received by the director to
which the director is not entitled; (b) an intentional infliction of harm on the
Company or its shareholders; (c) certain unlawful distributions to shareholders;
and (d) an intentional violation of criminal law. The effect of this provision
is to limit or eliminate the rights of the Company and its shareholders (through
shareholders' derivative suits on behalf of the Company) to recover money
damages from a director for all actions or omissions as a director (including
breaches resulting from negligent or grossly negligent behavior) except in the
situations described in clauses (a) through (d) above. This provision does not
limit or eliminate the rights of the Company or any shareholder to seek
non-monetary relief, such as an injunction or rescission, in the event of a
breach of a director's duty of care. The Company's Articles of Incorporation do
not set forth such a provision eliminating or limiting director liability.

        Under the Business Corporation Act, indemnification is mandatory with
respect to directors in all circumstances in which indemnification is permitted
by the Business Corporation Act, subject to the requirements of the Business
Corporation Act. In addition, the Company may, in its sole discretion, indemnify
and advance expenses, to the fullest extent allowed by the Business Corporation
Act, to any person who incurs liability or expense by reason of such person
acting as an officer, employee, or agent of the Company, except where
indemnification is mandatory pursuant to the Business Corporation Act, in which
case the Company is required to indemnify to the fullest extent required by the
Business Corporation Act.

        The Company's Bylaws provide indemnification for any director or
officer of the Company for expenses actually incurred in connection with any
action, suit or proceeding to which such director, officer or employee of the
Company is a party or is threatened to be a party as a result of his or her
being a director, officer or employee of the Company or of any firm,
corporation, or organization which he or she served in any such capacity at the
request of the Company. Such indemnification shall be against expenses,
judgments, fines and amounts paid in settlement actually and reasonably
believed to be in the best interests of the Company, and, with respect to A
criminal action or proceeding for which the director of officer has no
reasonable cause to believe his or her conduct was unlawful. In addition, the
Company's officers and directors shall be indemnified for expenses actually
and reasonably incurred by him or her in connection with an action or suit by
or in the right of the Company to procure a judgement in its favor by reason of
the fact that such director or officer is or was an authorized representative
of the Company.

                          INDEPENDENT AUDITORS' REPORT



To the Board of Directors
Southern Arizona Bancorp, Inc.
  and Subsidiary
Yuma, Arizona

         We have audited the accompanying consolidated balance sheet of Southern
Arizona Bancorp, Inc. and Subsidiary as of December 31, 1995 and 1994, and the
related consolidated statements of income, stockholders' equity and cash flows
for the years then ended. These financial statements are the responsibility of
the Bancorp's management. Our responsibility is to express an opinion on these
financial statements based on our audits. The statements of income,
stockholders' equity and cash flows of Southern Arizona Bancorp, Inc. for the
year ended December 31, 1993 were audited by other auditors whose report, dated
January 21, 1994, expressed an unqualified opinion on those statements.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the 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 1995 and 1994 consolidated financial statements
referred to above present fairly, in all material respects, the financial
position of Southern Arizona Bancorp, Inc. and Subsidiary as of December 31,
1995 and 1994 and the results of their operations and their cash flows for the
years then ended in conformity with generally accepted accounting principles.

                   Notes to Consolidated Financial Statements

NOTE 1.     NATURE OF BANKING ACTIVITIES AND SIGNIFICANT ACCOUNTING POLICIES

NATURE OF BANKING ACTIVITIES:

Southern Arizona Bancorp, Inc. (the Bancorp) is a holding company which owns
100% of the stock of Southern Arizona Bank (the Bank). The Bank provides a full
range of banking service to its commercial, SBA, residential, agricultural and
consumer customers through its facilities located in Yuma, Arizona.

The Bank grants commercial, residential and consumer loans to customers located
primarily in southern Arizona. The loan portfolio includes a significant credit
exposure to the real estate industry of this area. As of December 31, 1995,
loans with real estate as collateral accounted for approximately 54.9% of total
loans. Substantially all of these loans are secured by first liens with an
initial loan to value ratio of generally not more than 60%.

The loans are expected to be repaid from cash flows or proceeds from the sale of
selected assets of the borrowers. The Bank's policy requires that collateral be
obtained on substantially all loans. Such collateral is primarily first trust
deeds on property.

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS:

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 disclosures of
contingent asset 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.

BASIS OF CONSOLIDATION:

The consolidated financial statements include all the accounts of the Bancorp
and the Bank. All material intercompany accounts and transactions have been
eliminated.

EARNINGS PER SHARE:

Earnings per share are computed using the weighted average method. The effect of
stock options on earnings per share was not material.

CASH AND CASH EQUIVALENTS:

For purposes of reporting cash flows, cash and cash equivalents includes cash on
hand, amounts due from banks (including cash items in process of clearing). Cash
flows from loans originated by the Bank, deposits, and federal funds purchased
are reported net.

The Bank maintains amounts due from banks which, at times, may exceed federally
insured limits. The bank has not experienced any losses in such accounts.

NOTE 1.     NATURE OF BANKING ACTIVITIES AND SIGNIFICANT ACCOUNTING POLICIES 
            (CONTINUED)

HELD TO MATURITY SECURITIES:

Securities classified as held to maturity are those debt securities the Bank has
both the intent and ability to hold to maturity regardless of changes in market
conditions, liquidity needs or changes in general economic conditions. These
securities are carried at cost adjusted for amortization of premium and
accretion of discount, computed by the interest method over their contractual
lives.

The sale of a security within three months of maturity date or after at least 85
percent of the principal outstanding has been collected is considered a maturity
for purposes of classification and disclosure.

AVAILABLE FOR SALE SECURITIES:

Securities classified as available for sale are those debt securities that the
Bank intends to hold for an indefinite period of time, but not necessarily to
maturity. Any decision to sell a security classified as available for sale would
be based on various factors, including significant movements in interest rates,
changes in the maturity mix of the Bank's assets and liabilities, liquidity
needs, regulatory capital considerations, and other similar factors. Securities
available for sale are carried at fair value. Unrealized gains or losses are
reported as increases or decreases in stockholders' equity, net of the related
deferred tax effect. Realized gains or losses, determined on the basis of the
cost of specific securities sold, are included in earnings.

TRANSFERS:

Transfers of debt securities into the held-to-maturity classification from the
available-for-sale classification are made at fair value on the date of
transfer. The unrealized holding gains or losses on the date of transfer are
retained as a separate component of stockholders' equity and in the carrying
value of the held-to-maturity securities. Such amounts are amortized over the
remaining contractual lives of the securities by the interest method.

LOANS:

Loans are stated at the amount of unpaid principal, reduced by net deferred loan
costs and an allowance for possible loan losses.

The allowance for credit losses is established through a provision for credit
losses charged to expense. Loans are charged against the allowance for credit
losses when management believes that collectibility of the principal is
unlikely. The allowance is an amount that management believes will be adequate
to absorb estimated losses on existing loans that may become uncollectible,
based on evaluation of the collectibility of loans and prior loan loss
experience. This evaluation also takes into consideration such factors as
changes in the nature and volume of the loan portfolio, overall portfolio
quality, review of specific problem loans, and current economic conditions that
may affect the borrower's ability to pay. While management uses the best
information available to make its evaluation, future adjustments to the
allowance may be necessary if there are significant changes in economic or other
conditions. In addition, the Federal Deposit Insurance Corporation (FDIC), as an
integral part of their examination process, periodically reviews the Bank's
allowance for credit losses, and may require the Bank to make additions to the
allowance based on their judgment about information available for them at the
time of their examinations.

                   Notes to Consolidated Financial Statements

NOTE 1.     NATURE OF BANKING ACTIVITIES AND SIGNIFICANT ACCOUNTING POLICIES 
            (CONTINUED)

Impaired loans are measured based on the present value of expected future cash
flows discounted at the loan's effective interest rate or, as a practical
expedient, at the loan's observable market price or the fair value of the
collateral if the loan is collateral dependent. A loan is impaired when it is
probable the creditor will be unable to collect all contractual principal and
interest payments due in accordance with the terms of the loan agreement.

INTEREST AND FEES ON LOANS:

Interest on loans is recognized over the terms of the loans and is calculated on
principal amounts 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.

Loan origination and commitment fees and certain direct loan origination costs
are deferred and the net amount amortized as an adjustment of the related loan's
yield. The Bank is generally amortizing these amounts over the contractual life.

SALES OF LOANS:

The Bank sells loans to provide funds for additional lending and to generate
servicing income. Under such agreement, the Bank may continue to service the
loans with the buyer receiving the principal collected together with interest.
Loans held for sale are valued at the lower of cost or market value.

Gains and losses on sales are recognized at the time of sale are calculated
based on the difference between the selling price and the book value of loans
sold. Any inherent risk of loss on loans sold is transferred to the buyer at the
date of sale.

OTHER REAL ESTATE OWNED:

Other real estate owned (OREO) represents properties acquired through
foreclosure or other proceedings. OREO is held for sale and is recorded at the
lower of the recorded amount of the loan or fair value of the properties less
estimated costs of disposal. Any write-down to fair value at the time of
transfer to OREO is charged to the allowance for loan losses. Property is
evaluated regularly to ensure the recorded amount is supported by its current
fair value and valuation allowances to reduce the carrying amounts to fair value
less estimated costs to dispose. Depreciation is recorded based on the recorded
amount of depreciable assets after they have been owned for one year.
Depreciation and additions to or reductions from valuation allowances are
recorded in income.

following estimated useful lives:

INCOME TAXES:

The Bank files its income tax return on a consolidated basis. Deferred taxes are
provided on a liability method whereby deferred tax assets are recognized for
deductible temporary differences and operating loss and tax credit carryforwards
and deferred tax liabilities are recognized for taxable temporary differences.
Temporary differences are the differences between the reported amounts of assets
and liabilities and their tax bases. Deferred tax assets are reduced by a
valuation allowance when, in the opinion of management, it is more likely than
not that some portion or all of the deferred tax assets will not be realized.
Deferred tax assets and liabilities are adjusted for the effects of changes in
tax laws and rates on the date of enactment.

FAIR VALUE OF FINANCIAL INSTRUMENTS:

Effective January 1, 1995, the Bank adopted FASB Statement No. 107, Disclosures
About Fair Value of Financial Instruments, which requires disclosure of fair
value information about financial instruments, whether or not recognized in the
balance sheet, for which it is practicable to estimate that value.

Management uses its best judgment in estimating the fair value of the Bank's
financial instruments; however, there are inherent weaknesses in any estimation
technique. Therefore, for substantially all financial instruments, the fair
value estimates presented herein are not necessarily indicative of the amounts
the Bank could have realized in a sales transaction at December 31, 1995. The
estimated fair value amounts for 1995 have been measured as of year end, and
have not been reevaluated or updated for purposes of these financial statements
subsequent to that date. As such, the estimated fair values of these financial
instruments subsequent to the reporting date may be different than the amounts
reported at each year end.

This disclosure of fair value amounts does not include the fair values of any
intangibles, including core deposit intangibles.

Due to the wide range of valuation techniques and the degree of subjectivity
used in making the estimate, comparisons between the Bank's disclosures and
those of the banks may not be meaningful.

                   Notes to Consolidated Financial Statements

NOTE 1.     NATURE OF BANKING ACTIVITIES AND SIGNIFICANT ACCOUNTING POLICIES
            (CONTINUED)

The following methods and assumptions were used by the Bank in estimating the
fair value of its financial instruments:

    Cash and short-term instruments: The carrying amounts reported in the
    balance sheet for cash and due from banks, interest bearing deposits and
    federal funds sold approximate their fair values.

    Securities: Carrying amounts approximate fair values for securities
    available for sale. Fair values for securities held to maturity are based on
    quoted market prices.

    Loans: For variable-rate loans that reprice frequently and that have
    experienced no significant change in credit risk, fair values are based on
    carrying values. At December 31, 1995, variable rate loans comprised
    approximately 71% of the loan portfolio. Fair values for all other loans are
    estimated based on discounted cash flows, using interest rates currently
    being offered for loans with similar terms to borrowers with similar credit
    quality. Prepayments prior to the repricing date are not expected to be
    significant. Loans are expected to be held to maturity and any unrealized
    gains or losses are not expected to be realized.

    Loans held for sale: Fair value of loans held for sale are estimated based
    upon the subsequent selling price.

    Off-balance sheet instruments: Fair values of off-balance sheet instruments
    are not considered material.

    Deposit liabilities: Fair values disclosed for demand deposits equal their
    carrying amounts, which represent the amount payable on demand. The carrying
    amounts for variable-rate money market accounts and certificates of deposit
    approximate their fair values at the reporting date. Fair values for
    fixed-rate certificates of deposit are estimated using a discounted cash
    flow calculation that applies interest rates currently being offered on
    certificates to a schedule of aggregate expected monthly maturities on time
    deposits. Early withdrawals of fixed-rate certificates of deposit are not
    expected to be significant.

    Accrued interest receivable and payable: The fair values of both accrued
    interest receivable and payable approximate their carrying amounts.

ACCOUNTING BY CREDITORS FOR IMPAIRMENT OF A LOAN:

On January 1, 1995, the Bank adopted Financial Accounting Standards Board (FASB)
Statement No. 114, Accounting by Creditors for Impairment of a Loan, as amended
by FASB Statement No. 118, Accounting by Creditors for Impairment of a Loan -
Income Recognition and Disclosures. There was no effect on the Bank's financial
statements for this change, which generally requires impaired loans to be
measured on the present value of expected future cash flows discounted at the
loan's effective interest rate, or as an expedient at the loan's observable
market price or the fair value of the collateral if the loan is collateral
dependent. A loan is impaired when it is probable the creditor will be unable to
collect all contractual principal and interest payments due in accordance with
the terms of the loan agreement. At January 1, 1995, the Bank has classified
$1,313,529 of its loans as impaired with a specific loss reserve of $387,000.

            (CONTINUED)

ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE
DISPOSED OF:

In March 1995, the FASB issued Statement No. 121, Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to be Disposed of. Statement No.
121 establishes accounting standard for the impairment of long-lived assets,
certain identifiable intangibles, and goodwill related to those assets to be
held and used and for long-lived assets and certain identifiable intangibles to
be disposed of. Statement No. 121 will first be required for the Bank's year
ending December 31, 1996. Based on its preliminary analysis, the Bank does not
anticipate that the adoption of Statement No. 121 will have a material impact on
the financial statements as of the date of adoption.

ACCOUNTING FOR MORTGAGE SERVICING RIGHTS:

In May 1995, the FASB issued Statement No. 122, Accounting for Mortgage
Servicing Rights an Amendment of Financial Accounting Standards Board Statement
No. 65. Statement No. 122 requires a mortgage banking enterprise to recognize as
separate assets, rights to service mortgage loans for others, whenever those
servicing rights are acquired. Statement No. 122 will first be required for the
Bank's year ending December 31, 1996. The Bank has not addressed the potential
future impact of the application of this Statement.

ACCOUNTING FOR STOCK-BASED COMPENSATION:

In October 1995, the FASB issued Statement No. 123, Accounting for Stock-Based
Compensation. Statement No. 123 establishes financial accounting and reporting
standards for stock-based employee compensation plans such as a stock purchase
plan. The statement generally suggests, but does not require, stock-based
compensation transactions be accounted for based on the fair value of the
consideration received or the fair value of the equity instrument issued,
whichever is more reliably measurable. An enterprise may continue to follow the
requirements of Accounting Principles Board (APB) Opinion No. 25, which does not
require compensation to be reported if the consideration to be received is at
least equal to its fair value at the measurement date. If an enterprise elects
to follow APB Opinion No. 25, it must disclose the proforma effects on net
income as if the compensation were measured in accordance with the guidelines of
Statement No. 123. The Bank has not determined if it will continue to follow APB
Opinion No. 25 or follow the guidance of Statement No. 123. However, if adopted
in 1996, this pronouncement is not expected to have a material impact on the
financial statements.

NOTE 2.     RESTRICTIONS ON CASH AND DUE FROM BANKS

The Bank is required to maintain reserve balances with Federal Reserve Banks.
The total of those reserve balances were approximately $51,000 and $63,000 at
December 31, 1995 and 1994, respectively.

NOTE 8. NOTES PAYABLE SENIOR NOTES PAYABLE:

Bancorp has issued $2,500,000 of 8.75% Senior Notes payable which require that
interest be paid semi-annually. These notes are due July 1, 2000. The net
proceeds from the issuance were contributed to be capital of the Bank. The terms
of the Senior Notes include certain restrictions on the issuance of additional
debt and payment of dividends. The costs, totaling approximately $154,000, of
issuing the Senior Notes have been deferred and are being amortized over the
contract terms of such notes.

OTHER NOTES PAYABLE:

Other notes payable consists of a 8.5% note payable to a director arising from
the purchase of the land for the Bank's San Luis branch. Principal in the amount
of $120,000 per year, plus interest, is due commencing January 1996. Final
payment is due January 1999. The note is secured by real estate.

NOTE 9.    COMMITMENTS AND CONTINGENCIES

FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK:

The Bank is a 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 consist of commitments to extend credit. These instruments
involve, to varying degrees, elements of credit risk in excess of the amount
recognized in the 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 is
represented by the contractual amount of those instruments. The Bank uses the
same credit policies in making conditional obligations as they do for
on-balance-sheet instruments. A summary of the Bank's commitments at December
31, 1995 and 1994 are as follows:



                                                       1995            1994
                                                   ----------------------------

                                                                      
   Commitments to extend credit                    $ 16,384,611    $ 12,604,126
                                                   ============================


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. Since many
of the commitments are expected to expire without being drawn upon, the total
commitment amount does 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.

CONCENTRATIONS OF CREDIT RISK:

All of the Bank's loans and commitments to extend credit have been granted to
customers in the Bank's market area. The concentrations of credit by type of
loan are set forth in Note 4. The distribution of commitments to extend credit
approximates the distribution of commercial and real estate loans outstanding.
The Bank, as a matter of policy, does not extend credit to any single borrower
or group of related borrowers in excess of the Bank's legal lending limit.

Rent expense totaled approximately $52,063, $33,768, and $32,436 for the years
ended December 31, 1995, 1994, and 1993, respectively, and is included in
occupancy expense.

CONTINGENCIES:

In the normal course of business, the Bank is involved in various legal
proceedings. In the opinion of management, any liability resulting from such
proceedings would not have a material adverse effect on the Bank's financial
statements.

STOCK OPTIONS:

At December 31, 1995 and 1994, there were 57,000 shares of stock available for
grant under a company stock option plan. No options were outstanding. The option
price of the shares may not be less than the fair market value of common shares
as of the date of grant.

SALES OF LOANS:

The Bank has issued various representations and warranties associated with the
sale of loans. These representations and warranties may require the Bank to
repurchase loans with underwriting deficiencies as defined per the applicable
sales agreements. The Bank experienced no losses during the years ended December
31, 1995 and 1994, regarding these representations and warranties.

The Bank has had, and may be expected to have in the future, banking
transactions in the ordinary course of business with directors, principal
officers, their immediate families and affiliated companies in which they are
principal stockholders (commonly referred to as related parties), all of which
have been, in the opinion of management, on the same terms, including interest

NOTE 12.  EMPLOYEE BENEFIT PLAN

The Bank has adopted a 401(k) plan (the Plan) and sponsored an employee stock
ownership plan (ESOP) to which the Bank makes contributions. All full-time and
part-time employees of the Bank who have completed 1,000 hours per year and have
reached 21 years of age are eligible to participate.

Under the 401(k) plan, the Bank matches 100% of employee contributions.
Contributions to the Plan totalled approximately $89,000, $83,000, and $71,000
for the years ended December 31, 1995, 1994, and 1993, respectively.

The Bank makes voluntary contributions to the ESOP each year. Participants vest
in the contributions over a five year period. Common stock of the Bancorp held
by the ESOP is voted by the ESOP's administrative committee, consisting of three
members of the Board of Directors. For the years ended December 31, 1995, 1994,
and 1993, contributions were approximately $54,000, $123,000, and $128,000,
respectively.

In the event a terminated ESOP participant desires to sell his or her shares of
the Company's stock, the Company may be required to purchase the shares from the
participant. At December 31, 1995, the ESOP held 66,851 shares of Bancorp stock.

NOTE 13.  REGULATORY CAPITAL REQUIREMENTS

The Bank is subject to various regulatory capital requirements administered by
the 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
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve qualitative 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 (as defined in the regulations) to risk-
weighted assets (as defined), and of Tier I capital (as defined) to average
assets (as defined). Management believes, as of December 31, 1995, that the Bank
meets all capital adequacy requirements to which it is subject.

As of December 31, 1995, the most recent notification from the FDIC 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 management
believes have changed the institution's category.

                       Years Ended December 31, 1993-1995

RESULTS OF OPERATIONS

Average Balance, Interest Rates and Yields. The following table presents for the
periods indicated the total dollar amount of interest income from average
interest-earning assets and the resultant yields, as well as the interest
expense on average interest-bearing liabilities, expressed both in dollar
amounts and rates, and the net interest margin. The table does not reflect any
effect of income taxes. All average balances are monthly average balances and
include the balances of non-accruing loans. The yields and costs for the periods
indicated include fees which are considered adjustments to yield.

                         Analysis of Change in Interest
                      Years Ended December 31, 1994 - 1995

RATE/VOLUME OF NET INTEREST INCOME

The following schedule presents the dollar amount of changes in interest income
and interest expense for major components of interest-earning assets and
interest-bearing liabilities. It distinguishes between the increase related to
higher outstanding balances and that due to interest rates. For each category of
interest-earning assets and interest-bearing liabilities, information is
provided on changes attributable to (i) changes in volume (i.e., changes in
volume multiplied by old rate) and (ii) changes in rate multiplied by old
volume. Changes attributable to both rate and volume which cannot be segregated
have been allocated proportionately to the change due to volume and the change
due to rate.
