PART -- I

ITEM 1 -- BUSINESS

GENERAL

Sterling Bancshares, Inc. (the "Company"), headquartered in Houston, Texas, is a
bank holding company that provides commercial and retail banking services in
Houston, Texas through the community banking offices of Sterling Bank, a banking
association chartered under the laws of the State of Texas (the "Bank"). The
Company's principal executive offices are located at 15000 Northwest Freeway,
Houston, Texas, 77040 and its telephone number is (713) 466-8300. The Company
was incorporated under the laws of the State of Texas in 1980 and became the
parent bank holding company of the Bank in 1981. The Bank was chartered in 1974.
The Company completed its initial public offering on October 22, 1992. The
Company had approximately 461 full time equivalent employees, including 117
officers, as of December 31, 1997. At December 31, 1997, the Company had total
assets of $1.2 billion, deposits of $1.0 billion and shareholders' equity of
$80.0 million.

FINANCIAL SERVICES

The Bank provides a wide range of retail and commercial banking services,
including demand, savings and time deposits; commercial, real estate and
consumer loans; merchant credit card services; letters of credit; cash
management services; and drive-in banking services. In addition, the Bank
facilitates sales of brokerage, mutual funds, and insurance products through
third-party vendors. The deposits of the Bank are insured by the Bank Insurance
Fund ("BIF") of the Federal Deposit Insurance Corporation ("FDIC"). The primary
lending focus of the Bank is on commercial loans and owner-occupied real estate
loans to local businesses with annual sales ranging from $300,000 to $30
million. Typically, the Bank's customers have financing requirements between
$100,000 and $500,000. The Bank does not seek loans of more than $2 million but
will consider larger lending relationships which involve exceptional levels of
credit quality. The Bank's credit range, while well below its legal lending
limit of $12 million, allows for greater diversity in the loan portfolio, less
competition from large banks, and better pricing opportunities.

SUPERCOMMUNITY BANKING STRATEGY

The Company's business strategy is generally known as a supercommunity bank
strategy. Under this strategy, the Company provides a broad line of financial
products and services to small and medium-sized businesses and consumers through
full service community banking offices. Each banking office has senior
management, with significant lending experience, who exercise substantial
authority over credit and pricing decisions, subject to loan committee approval
for larger credits. This decentralized management approach, coupled with
continuity of service by the same staff members, enables the Bank to develop
long-term customer relationships, maintain high quality service and respond
quickly to customer needs. The Company believes that its emphasis on local
relationship banking, together with a conservative approach to lending and
resultant high asset quality, are important factors in the success and growth of
the Bank.

The Company and the Bank have maintained a strong community orientation by,
among other things, supporting the active participation of staff members in
local charitable, civic, school, religious and community development activities.
Each banking office also appoints selected customers to a business development
board that assists in introducing prospective customers to the Bank and in
developing or improving products and services to meet customer needs. As a
result of the development of broad banking relationships with customers and the
convenience and service of the Bank's sixteen banking offices, lending and
investing activities are funded almost entirely by core deposits, approximately
three-fourths of which are demand and savings deposits.

The Company centralizes operational and support functions that are transparent
to customers in order to achieve consistency and cost efficiencies in the
delivery of products and services by each banking office. The central office of
the Company provides services such as data processing, bookkeeping, accounting,
loan administration, loan review, compliance, legal management, and internal
auditing to all sixteen community banking offices to enhance their ability to
compete effectively. The Company also provides overall direction in the areas of
credit policy and administration, strategic planning, marketing, investment
portfolio management,



                                       2
<PAGE>   3

and other financial and administrative services. The community banking offices
work closely with the Company to develop new products and services needed by
their customers and introduce enhancements to existing products and services.

EXPANSION

The Company's growth strategy has been concentrated on increasing its community
banking presence in its existing markets, and expanding into new communities
within the greater Houston area in response to the express needs of those
communities. The Company has grown through a combination of internal growth,
mergers and acquisitions, and the opening of new community banking offices.

On February 17, 1998, the Company entered into an Agreement and Plan of
Consolidation (the "Consolidation Agreement") to acquire Humble National Bank
("Humble National") in a stock-for-stock merger. At December 31, 1997, Humble
National had total assets of $54.2 million and total deposits of $49.6 million.
Humble National operates a full service banking office at FM 1960 East Bypass
and U.S. Highway 59 in the Humble area of northeast Houston, as well as three
in-store supermarket locations in Humble, Atascocita and Porter, Texas. The
Consolidation Agreement, which is subject to the approval of the Humble National
shareholders and various banking regulatory agencies, provides for the issuance
of 855,000 shares (after the February 1998 stock split) of the common stock of
the Company to the shareholders of Humble National in exchange for all of the
issued and outstanding shares of Humble National common stock.

On September 30, 1997, the Company completed the acquisition of First Houston
Bancshares, Inc. ("First Houston") and its wholly owned subsidiary bank, Houston
National Bank ("Houston National"), in a stock-for-stock merger which has been
accounted for as a pooling of interests. The shareholders of First Houston were
issued 0.69 shares of common stock of the Company in exchange for each of their
shares of First Houston common stock and 6.9 shares of the Company's common
stock for each of their shares of First Houston preferred stock, resulting in
the issuance of a total of 1,686,014 shares of the Company's common stock. The
acquisition of First Houston added $135 million in total assets and $125 million
in total deposits to the Company's balance sheet. All previously issued
financial statements have been restated to reflect the acquisition of First
Houston. On October 27, 1997, Houston National was merged into the Bank adding
the Bayou Bend Office at 5757 Memorial Drive as the Bank's fifteenth banking
office.

In September 1996, the Bank acquired a 40% equity interest and a 44% voting
interest in Sterling Capital Mortgage Company ("SCMC"), a Houston-based
originator and servicer of single family residential mortgages. SCMC has loan
production offices throughout Texas and in Arizona, Colorado, Florida, Illinois,
Nevada, and North Carolina. For the year ended December 31, 1997, SCMC funded
approximately $600 million in residential mortgage loans. A substantial portion
of SCMC's loan production is generated through joint ventures known as
affiliated business arrangements with established home builders, realtor-based
organizations, and banking trade associations.

On December 31, 1993, the Company purchased Enterprise Bank - Houston
("Enterprise") for $15 million. Throughout 1994, the Company operated Enterprise
as a separate banking subsidiary with three community banking offices. On March
4, 1994, the Company merged with Guardian Bancshares, Inc. ("Guardian"), the
parent company of Guardian Bank of Houston, which had deposits of approximately
$90 million, in a transaction accounted for as a pooling of interests. The
Company operated Guardian as a separate bank subsidiary until it was merged with
and into the Bank concomitantly with Enterprise on January 3, 1995.

During 1996, the Company opened two new community banking offices, the first in
the Upper Kirby district of central Houston, and the second in the Galleria area
of Houston. The Company opened a full service office in the Cypress Station
area, north of the city, in January 1997. In January 1998, the Bank opened its
sixteenth office on Spencer Highway in Pasadena, Texas. The Company has entered
into a lease agreement for another banking office to be located in the Fountains
on the Lake shopping center in Fort Bend County at Corporate Drive and U.S.
Highway 59. The opening of this new office is subject to receipt of all required
regulatory approvals and is expected to occur during the second quarter of 1998.



                                       3
<PAGE>   4

The Company will continue to seek acquisition and new office opportunities where
available and consistent with its community banking philosophy. To accommodate
further growth, the Company continues to upgrade its central office data
processing and telecommunication systems and facilities to provide the Company
with the technological capacity necessary to meet the needs and expectations of
its customers and accommodate further growth in the Company's assets and number
of offices.

COMPETITION

The Bank engages in highly competitive activities. Each activity and market
served involves competition with other banks, as well as with non-banking and
non-financial enterprises which offer financial products and services that
compete directly with the Bank's product and service offerings. The Bank
actively competes with other banks in its efforts to obtain deposits and make
loans, in the scope and types of services offered, in interest rates paid on
time deposits and charged on loans and in other aspects of banking.

In addition to competing with other commercial banks within and outside their
primary service area, the Bank competes with other financial institutions
engaged in the business of making loans or accepting deposits, such as savings
and loan associations, credit unions, industrial loan associations, insurance
companies, small loan companies, finance companies, mortgage companies, real
estate investment trusts, certain governmental agencies, credit card
organizations and other enterprises. In recent years, competition for funds from
securities brokers for money market accounts has also intensified. Additional
competition for deposits comes from government and private issues of debt
obligations and other investment alternatives for depositors such as money
market funds. The Bank also competes with a variety of other institutions in the
provision of brokerage services.

SUPERVISION AND REGULATION_

References herein to applicable statutes and regulations are brief summaries
thereof, do not purport to be complete and are qualified in their entirety by
reference to such statutes and regulations.

THE BANK HOLDING COMPANY

The Company and its second tier holding company, Sterling Bancorporation, Inc.,
are bank holding companies registered under the Bank Holding Company Act of
1956, as amended ("BHCA"), and are subject to supervision and regulation by the
Federal Reserve Board. Federal laws subject bank holding companies to particular
restrictions on the types of activities in which they engage, and to a range of
supervisory requirements and activities, including regulatory enforcement
actions for violations of laws and policies. In addition, Texas law authorizes
the Texas Department of Banking to supervise and regulate a holding company
controlling a state bank.

PERMISSIBLE ACTIVITIES

As a bank holding company, the activities of the Company, as well as the
activities of entities which are controlled by the Company or of which the
Company owns 5% or more of the voting securities, are limited by the BHCA to
banking, management and control of banks, furnishing or performing services for
its subsidiaries, or any other activity which the Federal Reserve Board
determines to be incidental or closely related to banking or managing or
controlling banks. In approving acquisitions by the Company of entities engaged
in banking-related activities, the Federal Reserve Board considers a number of
factors, including the expected benefits to the public, such as greater
convenience and increased competition or gains in efficiency, which are weighted
against the risks of possible adverse effects, such as an attempt to monopolize
the business of banking, undue concentration of resources, decreased or unfair
competition, conflicts of interest, or unsound banking practices.

NON-BANKING ACTIVITIES

The BHCA sets forth exceptions to its general prohibition against bank holding
company ownership of voting shares in any company engaged in non-banking
activities. The exceptions include certain activities exempt based upon the type
of activity and those determined by the Federal Reserve Board to be closely
related to



                                       4
<PAGE>   5

banking or managing or controlling banks. The Economic Growth and Regulatory
Paperwork Reduction Act of 1996 ("EGRPRA"), signed into law on September 30,
1996, streamlined the non-banking activities application process for bank
holding companies which qualified as well-capitalized and well-managed. Under
the EGRPRA, qualified bank holding companies may commence a regulatory approved
non-banking related activity if they provide 12 days prior notice to the Federal
Reserve Board, assuming the size of the acquisition does not exceed 10% of
risk-weighted assets of the acquiring bank holding companies and the
consideration does not exceed 15% of Tier 1 capital (which is more fully
described below).

SAFETY AND SOUNDNESS STANDARDS

The Financial Institutions Reform, Recovery and Enforcement Act of 1989
("FIRREA") expanded the Federal Reserve Board's authority to prohibit activities
of bank holding companies and their non-banking subsidiaries which represent
unsafe and unsound banking practices or which constitute violations of laws or
regulations. Notably, FIRREA increased the amount of civil money penalties which
the Federal Reserve Board can assess for certain activities conducted on a
knowing and reckless basis, if those activities cause a substantial loss to a
depository institution. The penalties can be as high as $1 million per day.
FIRREA also expanded the scope of individuals and entities against which such
penalties may be assessed.

On July 10, 1995, the four federal agencies that regulate banks and savings
associations (FDIC, Federal Reserve Board, OCC and the Office of Thrift
Supervision) jointly issued guidelines for safe and sound banking operations
(Interagency Guidelines Establishing Standards for Safety and Soundness) as
required by Section 132 of the Federal Deposit Insurance Corporation Improvement
Act ("FDICIA"). The guidelines identify the fundamental standards that the four
agencies follow when evaluating the operational and managerial controls at
insured institutions. An institution's performance will be evaluated against
these standards during the regulators' periodic on-site examinations.

CAPITAL ADEQUACY REQUIREMENTS

The Federal Reserve Board monitors the capital adequacy of bank holding
companies. The Bank is subject to the capital adequacy requirements promulgated
by the FDIC and the Texas Department of Banking.

The Federal Reserve Board has adopted a system using risk-based capital adequacy
guidelines to evaluate the capital adequacy of bank holding companies. Under the
risk-based capital guidelines, different categories of assets are assigned
different risk weights, based generally on the perceived credit risk of the
asset. These risk weights are multiplied by corresponding asset balances to
determine a "risk-related" asset base. Certain off balance sheet items are added
to the risk-weighted asset base by converting them to a balance sheet equivalent
and assigning to them the appropriate risk weight. In addition, the guidelines
define each of the capital components. Total capital is defined as the sum of
"core capital elements" ("Tier 1") and "supplemental capital elements" ("Tier
2"), with "Tier 2" being limited to 100% of "Tier 1." For bank holding
companies, "Tier 1" capital includes, with certain restrictions, common
shareholders' equity, perpetual preferred stock, and minority interest in
consolidated subsidiaries. "Tier 2" capital includes, with certain limitations,
certain forms of perpetual preferred stock, as well as maturing capital
instruments and the reserve for credit losses. The guidelines require
achievement of a minimum ratio of total capital-to-risk-weighted assets of 8.0%
(of which at least 4.0% is required to be comprised of "Tier 1" capital
elements). At December 31, 1997, the Company's ratios of "Tier 1" and "Total"
capital-to-risk-weighted assets were 12.45%, and 13.56%, respectively.

In addition to the risk-based capital guidelines, the Federal Reserve Board and
the FDIC have adopted the use of a minimum Tier 1 leverage ratio as an
additional tool to evaluate the capital adequacy of banks and bank holding
companies. The banking organization's Tier 1 leverage ratio is defined to be a
company's "Tier 1" capital divided by its average total consolidated assets. The
leverage ratio adopted by the federal banking agencies requires a minimum 3.0%
"Tier 1" capital to total assets ratio for institutions with the highest
regulatory rating. All other institutions will be expected to maintain a
leverage ratio of 4.0% to 5.0%. The Company's leverage ratio at December 31,
1997 of 11.05% significantly exceeded the regulatory minimum.

<PAGE>   6

IMPOSITION OF LIABILITY FOR UNDERCAPITALIZED SUBSIDIARIES

A bank holding company that fails to meet the applicable risk-based capital
standards will be at a disadvantage. For example, Federal Reserve Board policy
discourages the payment of dividends by a bank holding company from borrowed
funds as well as payments that would adversely affect capital adequacy. Failure
to meet the capital guidelines may result in institution of appropriate
supervisory or enforcement actions by the Federal Reserve Board. FDICIA requires
bank regulators to take "prompt corrective action" to resolve problems
associated with insured depository institutions whose capital declines below
certain levels.

AUDIT REPORTS

As of January 1, 1994, FDICIA amended the Federal Deposit Insurance Act to
include provisions to strengthen the ability of the banking regulatory system to
identify deficiencies in financial management of insured deposit institutions.
The regulations promulgated by the FDIC to implement this part of FDICIA require
depository institutions with assets of $500 million or more to conform to the
new procedures. Commencing in 1996, the Bank qualified as an institution with
assets of more than $500 million and became subject to the audit and reporting
requirements of FDICIA. FDICIA requires insured institutions to submit annual
audit reports prepared by independent auditors to federal and state regulators.
The audit report of the institution's holding company can be used to satisfy
this requirement. Auditors must apply procedures agreed to by the FDIC to
determine compliance by the institution or holding company with legal
requirements designated by FDICIA. The annual audit report must include
financial statements prepared in accordance with generally accepted accounting
principles, statements concerning management's responsibility for the financial
statements and internal controls designated by the FDIC, and an attestation by
the auditor regarding the statements of management. For certain large
institutions, independent auditors may be required to review quarterly financial
statements. FDICIA requires that independent audit committees be formed,
consisting solely of outside directors. The Company has an audit committee
comprised of outside directors who are certified public accountants and,
therefore, is in compliance with the requirements for large institutions.

ACQUISITIONS BY BANK HOLDING COMPANIES

Federal Reserve Board Approval. The BHCA requires a bank holding company to
obtain the prior approval of the Federal Reserve Board before it may acquire all
or substantially all of the assets of any bank, or ownership or control of any
voting shares of any bank, if after such acquisition it would own or control,
directly or indirectly, more that 5% of the voting shares of such bank. In
approving bank acquisitions, the Federal Reserve Board considers the financial
and managerial resources and future prospects of the bank holding company and
the banks concerned, the convenience and needs of the communities to be served,
and various competitive factors. The Attorney General of the United States may,
within 30 days after approval of an acquisition by the Federal Reserve Board,
bring an action challenging such acquisition under the federal antitrust laws,
in which case the effectiveness of such approval is stayed pending a final
ruling by the courts.

Mergers of Banks and Thrifts. FDICIA has eased restrictions on cross-industry
mergers. Members of the Bank Insurance Fund ("BIF") and the Savings Association
Insurance Fund ("SAIF") are generally allowed to merge, assume each other's
deposits, and transfer assets in exchange for an assumption of deposit
liabilities. A formula applies to treat insurance assessments relating to
acquired deposits as if they were still insured through the acquired
institutions' insurance fund. The transaction must be approved by the
appropriate federal banking regulator. In considering such approval, the
regulators take into account applicable capital requirements, certain interstate
banking restrictions, and other factors.


COMMUNITY REINVESTMENT ACT

The Community reinvestment Act of 1977 ("CRA") and the regulations promulgated
by the FDIC to implement CRA are intended to ensure that banks meet the credit
needs of their service area, including low and moderate income communities and
individuals, consistent with safe and sound banking practices. In 1995, the bank
regulatory agencies adopted final regulations for implementing CRA. These
regulations effect extensive changes to the existing procedures for determining
compliance with CRA. The CRA regulations also require



                                       6
<PAGE>   7

the banking regulatory authorities to evaluate a bank's record in meeting the
needs of its service area when considering applications to establish new offices
or consummate any merger or acquisition transaction. Under FIRREA, the federal
banking agencies are required to rate each insured institutions performance
under CRA and to make such information publicly available. In the case of an
acquisition by a bank holding company, the CRA performance record of the banks
involved in the transaction are reviewed as part of the processing of the
acquisition application. A CRA rating other than `outstanding' or `satisfactory'
can substantially delay or block the transaction.

INTERSTATE BANKING

The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (the
"Interstate Branching Act") has increased the ease and likelihood of interstate
acquisitions throughout much of the United States. The Interstate Branching Act
removes state law barriers to acquisitions in all states and allows multi-state
banking operations to merge into a single bank with interstate branches.
Interstate banking and branching authority will be subject to certain conditions
and restrictions, such as capital adequacy, management and Community
Reinvestment Act compliance. The Interstate Bank Act preempts existing barriers
that restrict entry into all states - such as regional compacts and reciprocity
agreements - thus creating opportunities for expansion into markets that were
previously closed. Under the law, bank holding companies are now able to acquire
banks in any state, subject to certain conditions. Banks acquired pursuant to
this authority may subsequently be converted to branches. Interstate branching
is permitted by allowing banks to merge across state lines to form a single
institution. Interstate merger transactions can be used to consolidate existing
multi-state operations or to acquire new branches. A bank may establish a new
branch as its initial entry into a state only if the state has authorized de
novo branching. In addition, out-of-state banks may merge with a single branch
of a bank if the state has authorized such a transaction. The Federal Reserve
Board, however, will only allow the acquisition by a bank holding company of an
interest in any bank located in another state if the statutory laws of the state
in which the target bank is located expressly authorize such acquisitions. The
interstate branching provisions became effective on June 1, 1997, unless a state
took action before that time. Texas elected to "opt out" of the Interstate
Branching Act. Despite Texas' having opted out of the Riegle-Neal Act, the Texas
Banking Act permits, in certain circumstances, out-of-state bank holding
companies to acquire certain existing banks and bank holding companies in Texas.

STERLING BANK

The Bank is a Texas-chartered banking association, the deposits of which are
insured by the FDIC, and is not a member of the Federal Reserve System.
Therefore, the Bank is subject to supervision and regulation by the FDIC and the
Texas Department of Banking. Pursuant to such regulation, the Bank is subject to
special restrictions, supervisory requirements and potential enforcement
actions. The Federal Reserve Board also has supervisory authority which directly
affects the Bank. The Bank is a member of the Federal Home Loan Bank and,
therefore, is subject to compliance with its requirements.

PERMISSIBLE ACTIVITIES FOR STATE-CHARTERED INSTITUTIONS

The Texas Constitution provides that a Texas-chartered bank has the same rights
and privileges that are or may be granted to national banks domiciled in Texas.
FDICIA provides that no state bank or subsidiary thereof may engage as principal
in any activity not permitted for national banks, unless the institution
complies with applicable capital requirements and the FDIC determines that the
activity poses no significant risk to the BIF.

BRANCHING

Texas law provides that a Texas-chartered bank can establish a branch anywhere
in Texas provided that the branch is approved in advance by the Commissioner of
the Texas Department of Banking (the "Commissioner"). The branch must also be
approved by the FDIC, which considers a number of factors, including financial
history, capital adequacy, earnings prospects, character of management, needs of
the community, and consistency with corporate powers. There are no federal
limitations on the ability of insured non-member state banks to branch across
state lines; however, such branching would be subject to applicable state law
restrictions.

RESTRICTIONS ON SUBSIDIARY BANKS

Dividends paid by the Bank are the primary source of the Company's cash flow.
Although the Bank elected in August 1997 to temporarily suspend the payment of
dividends to the Company and to use the proceeds from the issuance of $28.75
million of trust preferred securities by Sterling Bancshares Capital Trust I to
meet the Company's current cash flow needs, the Bank is expected to provide
substantially all of the Company's cash flow in the foreseeable future. Under
federal law, the Bank may not pay a dividend that results in an
"undercapitalized" situation. At December 31, 1997, there was an aggregate of
approximately $24.2 million available for the payment of dividends by the Bank
to the Company without prior regulatory approval.

Other requirements in Texas law affecting the operation of subsidiary banks,
include requirements relating to maintenance of reserves against deposits,
restrictions on the nature and amount of loans that may be made and the interest
that may be charged thereon and limitations relating to investments and other
activities.

EXAMINATIONS

The FDIC periodically examines and evaluates insured banks. FDIC examinations
are conducted every 12 months. FDICIA authorized the FDIC to assess the
institution for its costs of conducting the examinations.

The Commissioner also conducts examinations annually, unless additional
examinations are deemed necessary to safeguard the interests of shareholders,
depositors and creditors. The Commissioner may accept the results of a federal
examination in lieu of conducting an independent examination. However, since the
total assets of the Bank exceeded $1 billion at December 31, 1997, the FDIC and
the Texas Department of Banking will jointly examine the Bank on an annual
basis.

DEPOSIT INSURANCE ASSESSMENTS

The FDIC is required by the Federal Deposit Insurance Act to assess deposit
insurance premiums on all banks in order to adequately fund the BIF so as to
resolve any insured institution that is declared insolvent by its primary
regulator. FDICIA required the FDIC to establish a risk-based deposit insurance
premium schedule. The risk-based assessment system is used to calculate a
depository institution's semi-annual deposit insurance assessment based upon the
designated reserve ratio for the deposit insurance fund and the probability and
extent to which the deposit insurance fund will incur a loss with respect to the
institution. In addition, the FDIC can impose special assessments to cover the
cost of borrowings from the U.S. Treasury, the Federal Financing Bank, and BIF
member banks.

Under the current risk-based assessment system, each depository institution is
placed in one of nine assessment categories based on certain capital and
supervisory measures. Institutions assigned to higher-risk categories, which are
institutions that pose a greater risk of loss to their respective deposit
insurance funds, pay assessments at higher rates than institutions that pose a
lower risk.

In 1995, the FDIC amended its regulations to change the range of deposit
insurance assessments charged to BIF-members from the then-prevailing range of
0.23% to 0.31% of deposits, to a range of 0.04% to 0.31% of deposits. In
connection with the new rate schedule, the FDIC established a process for
raising or lowering all rates for BIF-insured institutions semi-annually if
conditions warrant. Under this new system, the FDIC has the flexibility to
adjust the entire BIF assessment rate schedule twice a year without seeking
public comment first, but only within a range of five basis points or five cents
per $100 above or below the premium schedule adopted. Changes in the rate
schedule outside the five basis points or five cent range above or below the
current schedule can be made by the FDIC only after following full rulemaking
procedures.

Utilizing its authority to adjust the assessment rate schedule, the FDIC
adjusted the original schedule by reducing the assessment rates four basis
points effective January 1, 1996. Therefore, the range of deposit insurance
assessment for the BIF-member institutions is currently between 0% and 0.27% of
deposits. BIF-member institutions which qualify under the 0% assessment category
are, however, required to pay only the $1,000 minimum semi-annual assessment
required by federal statute. Since both the Bank and Houston



                                       8
<PAGE>   9

National qualified for the 0% assessment, each bank was assessed the minimum
amount of $2,000 for the year ended December 31, 1997.

EGRPRA contains a comprehensive approach for recapitalizing the SAIF in order to
bring it into parity with the BIF and to assure payment of the Financing
Corporation's ("FICO") bond obligations. Under EGRPRA, BIF members are required
to pay a portion of the interest due on bonds that were issued by FICO to help
shore up the ailing Federal Savings and Loan Insurance Corporations ("FSLIC") in
1987. The amount of FICO debt service to be paid by all BIF-insured institutions
is estimated at $0.1296 per $100 of deposits from 1997 until the year 2000, when
the obligations of BIF-insured institutions increases to $0.240 per $100 of
deposits annually through the year 2019.

EXPANDING ENFORCEMENT AUTHORITY

One of the major additional impacts imposed on the banking industry by FDICIA is
the increased ability of banking regulators to monitor the activities of banks
and their holding companies. In addition, the Federal Reserve Board and FDIC
have extensive authority to police unsafe or unsound practices and violations of
applicable laws and regulations by depository institutions and their holding
companies. For example, the FDIC may terminate the deposit insurance of any
institution which it determines has engaged in an unsafe or unsound practice.
The agencies can also assess civil money penalties, issue cease and desist or
removal orders, seek injunctions, and publicly disclose such actions. FDICIA,
FIRREA and other laws have expanded the agencies' authority in recent years, and
the agencies have not yet fully tested the limits of their powers.

EFFECT ON ECONOMIC ENVIRONMENT

The policies of regulatory authorities, including the monetary policy of the
Federal Reserve Board, have a significant effect on the operating results of
bank holding companies and their subsidiaries. Among the means available to the
Federal Reserve Board to affect the money supply are open market operations in
U.S. government securities, changes in the discount rate on member bank
borrowings, and changes in reserve requirements against member bank deposits.
These means are used in varying combinations to influence overall growth and
distribution of bank loans, investments and deposits, and their use may affect
interest rates charged on loans or paid for deposits.

Federal Reserve Board monetary policies have materially affected the operating
results of commercial banks in the past and are expected to continue to do so in
the future. The nature of future monetary policies and the effect of such
policies on the business and earnings of the Company and its subsidiaries cannot
be predicted.

CONSUMER LAWS AND REGULATIONS

In addition to these laws and regulations, banks are also subject to certain
consumer laws and regulations that are designed to protect consumers in
transactions with banks. Among the more prominent of such laws and regulations
are the Truth in Lending Act, the Truth in Savings Act, the Electronic Funds
Transfer Act, the Expedited Funds Availability Act, the Equal Credit Opportunity
Act, the Fair Credit Reporting Act, and the Fair Housing Act. These laws and
regulations mandate certain disclosure requirements and regulate the manner in
which financial institutions must deal with customers when taking deposits or
making loans to such customers. The Bank must comply with the applicable
provisions of these consumer protection laws and regulations as part of their
ongoing customer relations.

YEAR 2000 COMPLIANCE

On May 5, 1997, the Federal Financial Institutions Examination Council ("FFIEC")
which is comprised of the four major banking regulatory agencies promulgated
guidelines that federally supervised financial institutions are expected to
follow to ensure that their information processing systems are Year 2000
compliant. The Year 2000 guidelines delineate specific actions and conversion
efforts which financial institutions should address and implement as part of the
Year 2000 planning process. The guidelines identify five critical phases which
each financial institution must incorporate into its Year 2000 program. The Year
2000 guidelines also address external and operating issues which must be
evaluated in the planning process. The federal banking agencies



                                       9
<PAGE>   10

have indicated that they will conduct supervisory reviews of all depository
institutions by mid-1998 and follow-up assessments throughout the remainder of
1998 and during 1999 and, if necessary, will schedule comprehensive on-site
examinations to evaluate the adequacy of each bank's Year 2000 plans and
conversion programs. In furtherance of the supervisory responsibilities of the
bank regulatory agencies, the FFIEC issued examination guidelines in December
1997 for evaluating the Year 2000 readiness of all federally supervised
financial institutions and data centers. The examination guidelines direct the
federal banking regulatory agencies to assess (i) each institution's
information, accounting and risk control systems, (ii) the awareness and
commitment of both the board of directors and management's to Year 2000 issues,
(iii) the allocation of resources and personnel to Year 2000 planning, (iv) the
scope and integrity of the institution's assessment, planning and corrective
efforts, (v) the scope and adequacy of testing plans, (vi) the reliance on
vendors and third party providers and the testing and validation of their
applications and systems, and (vii) the institution's assessment of the impact
of Year 2000 risks on bank customers, particularly with respect to credit
relationships. If the appropriate regulatory authority determines that the
examined institution has not appropriately addressed potential Year 2000 risks
and planning considerations, prompt corrective action or other enforcement
action may be taken. Both the Federal Reserve Board and the FDIC have conducted
on-site reviews of the Company's Year 2000 plan and compliance efforts and,
while no formal examination reports are being issued by the banking regulators,
they have indicated their satisfaction with the Company's Year 2000 plan and the
actions taken to date. Further information regarding the Company's Year 2000
plan and related initiatives is discussed further on page 14 at "MANAGEMENT'S
DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS."

ITEM 2 -- PROPERTIES

split (effected as a 50% stock dividend) to shareholders of record on February
10, 1997, with shares distributed on February 24, 1997. Concurrently with the
1997 stock split, the Company declared a quarterly $0.0367 cash dividend
(computed on an "after-split" basis) payable on February 24, 1997, to
shareholders of record on February 10, 1997.

On January 26, 1998, the Board of Directors declared a three-for-two stock split
(effected as a 50% stock dividend) of the Company's common stock distributed on
February 20, 1998, to shareholders of record on February 6, 1998. Concurrently
with the 1998 stock split, the Company declared a quarterly $0.04 cash dividend
(computed on an "after-split" basis) payable on February 20, 1998, to
shareholders of record on February 6, 1998. The Company intends to continue to

1997 and 1996 quarterly information disclosed above is reflective of both the
1998 and 1997 stock split.

As of March 1, 1998, there were 686 shareholders of record of common stock. The
number of beneficial shareholders is unknown to the Company at this time.

The Company's stock trades through the National Market System of the NASDAQ
under the symbol SBIB.

DESCRIPTION OF CAPITAL STOCK

AUTHORIZED CAPITAL STOCK

The authorized capital stock of the Company consists of (i) 30,000,000 shares of
Common Stock, $1.00 per share par value, of which 13,760,320, (20,640,480
restated for the 1998 stock split) were issued and outstanding as of December
31, 1997 and (ii) 1,000,000 shares of Preferred Stock, $1.00 per share par value



                                       11
<PAGE>   12

("Preferred Stock"), issuable in series, of which 49,500 shares of Series A,
38,880 shares of Series B, 38,500 shares of Series C and 50,233 shares of Series
D Convertible Preferred Stock were issued and outstanding as of December 31,
1997. As of December 31, 1997, an additional 346,547 (519,820 restated for the
1998 stock split) shares of Common Stock were issuable upon exercise of the
Company's vested outstanding employee stock options and pursuant to outstanding
subscriptions under the Company's Employee Stock Purchase Plan.

The following discussion of the terms and provisions of the Company's capital
stock is qualified in its entirety by reference to the Company's Articles of
Incorporation and bylaws, copies of which are included as exhibits.

COMMON STOCK

All outstanding shares of Common Stock are fully paid and nonassessable. There
are no preemptive, conversion, subscription, redemption or repurchase rights
associated with shares of Common Stock, except as exist under the 1994 Incentive
Stock Option Plan and the 1994 Employee Stock Purchase Plan. Each holder of
shares of Common Stock is entitled to one vote for each share held of record as
to all matters requiring a shareholder vote. Holders of shares of Common Stock
are not entitled to cumulative voting rights in the election of directors. Upon
the dissolution of the Company, the holders of Common Stock would be entitled to
participate ratably in the assets available for distribution after satisfaction
of the claims of creditors of the Company and of holders of any series of
Preferred Stock having a liquidation preference, to the extent of such
preference.

The holders of shares of the Common Stock are entitled to such dividends as the
Board of Directors, in its discretion, may declare out of funds legally
available therefor. Under the Texas Business Corporation Act, as amended (the
"TBCA"), dividends may not be paid if, after the payment, the Company's total
assets would be less than the sum of its total debts and stated capital, or if
the Company would be unable to pay its debts as they become due in the usual
course of its business. There can be no assurances such dividends will continue
to be paid in the future. Payment of future dividends will be dependent upon,
among other things, the Company's and the Bank's earnings and financial
condition, and the general economic and regulatory climate.

Funds for the payment of dividends by the Company are obtained primarily from
dividends received from the Bank. Certain restrictions exist regarding the
ability of the Bank to pay dividends to the Company. Under federal law, the Bank
cannot pay a dividend if it will cause the Bank to be "undercapitalized." The
regulators of the Bank and the Company may administratively impose stricter
limits on the ability of the Bank to pay dividends to the Company.

The Bank is also subject to risk based capital rules which restrict its ability
to pay dividends. The risk based capital rules set an explicit schedule for
achieving minimum capital levels in relation to risk weighted assets. The Bank
has been required to meet a minimum ratio of total capital to risk weighted
assets of 8.0%. As of December 31, 1997, the Bank was in compliance with all
capital requirements.

Effective March 15, 1997, Harris Trust and Savings Bank was appointed as the
transfer agent and registrar for the Common Stock.

PREFERRED STOCK

The Company's Preferred Stock (or other securities convertible in whole or in
part into Preferred Stock) is available for issuance from time to time for
various purposes as determined by the Company's Board of Directors, including,
without limitation, making future acquisitions, raising additional equity
capital and financings. Subject to certain limits set by its Articles of
Incorporation, the Preferred Stock (or such convertible securities) may be
issued on such terms and conditions, at such times and in such situations as the
Board of Directors, in its discretion, determines to be appropriate, without any
further approval or action by the shareholders (unless otherwise required by
laws, rules, regulations or agreements applicable to the Company).

ITEM 6 -- SELECTED FINANCIAL DATA

The following table sets forth summary historical data for the Company for the
periods indicated. Since Enterprise was acquired on December 31, 1993, but after
close of business operations for the year, historical results of operations for
1993 do not include Enterprise data. Balance sheet data and related ratios,
however, include Enterprise financial information on the consolidated basis for
1993 and subsequent periods. Since the Guardian merger during 1994 and the First
Houston merger during 1997 were accounted for using the "pooling of interests"
method, all data prior to the respective mergers have been restated to include
Guardian and First Houston balance sheet data and historical results of
operations. All per share data amounts have been restated for the 1998 stock
split.

ITEM 7 -- MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Management's Discussion and Analysis of Financial Condition and Results of
Operations of the Company analyzes the major elements of the Company's
consolidated balance sheets and statements of income. This section should be
read in conjunction with the Company's consolidated financial statements and
accompanying notes and other detailed information incorporated by reference.
Since the First Houston merger was accounted for using the "pooling of
interests" basis, all prior years have been restated to include First Houston
balance sheet data and historical results of operations.

The statements contained in this Annual Report which are not historical
statements of fact may constitute forward-looking statements within the meaning
of the Private Securities Litigation Reform Act of 1995. Any such
forward-looking statements involve a number of risks and uncertainties. The
actual results of future events could differ materially from those stated in any
forward-looking statements made in this Annual Report. Among the factors that
could cause actual results to differ materially are the risks and uncertainties
discussed in this Item 7 and the uncertainties set forth from time to time in
the Company's other public reports and filings and public statements. The
Company does not undertake, and specifically disclaims any obligation, to update
any forward-looking statements to reflect occurrences or unanticipated events or
circumstances after the date of such statements.

RESULTS OF OPERATIONS

PERFORMANCE SUMMARY

Net income for 1997 was $13.1 million, an increase of $1.9 million, or 17.0%
over the $11.2 million recorded for 1996. Net income of $11.2 million in 1996
increased $1.5 million, or 15.5% over the $9.7 million recorded for 1995. These
increases were primarily due to increased net interest income.

Diluted earnings per share for 1997 was $0.61 as compared to $0.53 for 1996 and
$0.47 for 1995. All per share amounts have been restated to reflect the stock
splits effective through February 20, 1998.

Two industry measures of the performance by a banking institution are its return
on average assets and return on average equity. Return on average assets ("ROA")
measures net earnings in relation to average total assets and indicates a
company's ability to employ its resources profitably. During 1997, the Company's
ROA was 1.27%, as compared to 1.37% and 1.38% for 1996 and 1995, respectively.
Return on average equity ("ROE") is determined by dividing annual net earnings
by average shareholders' equity and indicates how effectively a company can
generate net income on the capital invested by its shareholders. During 1997,
the Company's annualized ROE was 17.62% compared to 17.74% and 19.03% for 1996
and 1995, respectively.

NET INTEREST INCOME AND NET INTEREST MARGIN

Net interest income represents the amount by which interest income on
interest-earning assets, including investment securities and loans, exceeds
interest paid on interest-bearing liabilities, including deposits and other
borrowed funds. Net interest income is the principal source of the Company's
earnings. Interest rate fluctuations, as well as changes in the amount and type
of earning assets and liabilities, combine to affect net interest income.

Net interest income for 1997 was $54.5 million, compared to $42.4 million for
1996, an increase of $12.1 million or 28.6%. The improvement in net interest
income for 1997 was mainly due to an increase in total interest earning assets,
specifically in the loan portfolio. During 1997, the yield on interest earning
assets increased 9 basis points, from 8.51% in 1996 to 8.60% in 1997. Total
funding costs increased by 5 basis points from 3.76% in 1996 to 3.81% in 1997.
For 1997, the net interest margin (net interest income divided by average total
interest earning assets) increased 11 basis points to 5.91% from 5.80% in 1996.
The improvement in net interest margin is due to the increase in average
non-interest bearing deposits and issuance of trust preferred securities (as
discussed herein).

Net interest income for 1996 was $42.4 million, up $5.4 million or 14.5% from
$37.0 million for 1995. During 1996, the yield on interest earning assets
decreased 6 basis points from 8.57% in 1995 to 8.51% in 1996. For 1996 and 1995
total funding costs remained constant at 3.76%. For 1996, the net interest
margin (net interest income divided by average total interest-earning assets)
decreased 4 basis points to 5.80% from 5.84% for 1995.

(1)  Loan origination fees are considered adjustments to interest income. These
     fees aggregated $1,154,000, $724,000, and $603,000 for the years ended
     December 31, 1997, 1996 and 1995, respectively. Related loan origination
     costs are not separately allocated to loans, but are charged to
     non-interest expense. For the purpose of calculating loan yields, average
     loan balances include nonaccrual loans with no related interest income.
(2)  The net interest margin is equal to net interest income divided by average
     interest-earning assets.
(3)  In order to make pretax income and resultant yields on tax-exempt
     investments and loans comparable to those on taxable investments and loans,
     a tax-equivalent adjustment is made equally to interest income and income
     tax expense with no effect on after tax income. The tax equivalent
     adjustment has been computed using a federal income tax rate of 34%.

The following rate/volume analysis shows the portions of the net change in
interest income due to changes in volume or rate. The changes in interest income
due to both rate and volume in the rate/volume analysis table have been
allocated to volume or rate change in proportion to the absolute amounts of the
change in each (in thousands):

NONINTEREST INCOME

For 1997, noninterest income totaled $9.7 million, an increase of $1.1 million
or 13.3% over $8.6 million in 1996. The increase is primarily attributed to
volume growth in deposit accounts. Noninterest income of $8.6 million for the
year ended December 31, 1996, increased $530,000 or 6.6% over 1995, primarily
due to $316,000 in earnings recognized in 1996 from SCMC, an originator and
servicer of single family residential mortgage loans in which the Bank owns a
forty percent interest acquired in 1996. Also, compared to 1995 various customer
service fees increased due to an increase in deposit account transaction volume,
and an increase in the number of retail customers.

For the years 1997, 1996, and 1995, the Company's ratio of noninterest income to
total income (net interest income plus noninterest income, excluding the
expenses relating to the First Houston acquisition) was 15.16%, 16.87%, and
17.90%, respectively.

NONINTEREST EXPENSE

For 1997, noninterest expenses totaled $41.6 million, an increase of $9.3
million or 28.6% over $32.4 million in 1996. Salaries and employee benefits
including profit sharing provision for 1997 totaled $22.1 million, an increase
of $2.7 million or 13.9% over $19.4 million for 1996 due primarily to an
increase in the number of full time equivalent employees and routine salary
increases. The Bank increased its number of full-time equivalent personnel by 52
or 12.7% during the year, from 409 at year end 1996 to 461 at year end 1997.
Staffing of the new Cypress Station, Upper Kirby, and Fountainview offices
accounted for the majority of the staff increases, while the Central Office
added staff necessary to handle the additional volume growth of the Bank. Data
processing increased $1.3 million or 100.1% over 1996. The Bank underwent a
major core data processing system conversion during 1997 to better position
itself for serving its expanding customer base. Also, the acquisition of First
Houston required significant data processing expenditures. Finally, there were
significant costs relating to preparations to address year 2000 issues. During
1997, the Company issued through a wholly owned subsidiary, $28,750,000 in 9.28%
Cumulative Trust Preferred Securities which mature in 2027. See Note L in the
consolidated financial statements for further information about these
securities. The interest accrued on these securities is classified as minority
interest expense. There was no similar expense in 1996. Professional fees
increased $696,000 or 91.2% primarily as a result of the First Houston
acquisition and the issuance of the Trust Preferred Securities. Other expenses
increased by $2.8 million or 67.9%. These



                                       16
<PAGE>   17

expenses related primarily to the opening of three additional banking offices
during late 1996 and early 1997 as well the acquisition of First Houston.

For 1996, noninterest expenses totaled $32.4 million, an increase of $2.6
million or 8.7% over $29.8 million in 1995. Salaries and employee benefits
including profit sharing provision for 1996 totaled $19.4 million, an increase
of $2.2 million or 12.9% over $17.2 million for 1995 due primarily to an
increase in the number of full time equivalent employees and routine salary
increases. The Bank increased its number of full-time equivalent personnel by 54
or 15.2% during the year, from 355 at year end 1995 to 409 at year end 1996. The
FDIC assessment for 1996 totaled $4,000, a decrease of $671,000 or 99.4% over
$675,000 in 1995. The reduction is due to a change in the FDIC assessment rate
from $0.23 and $0.04 per $100 of deposits for the first and second half of 1995,
respectively, as compared to $2,000 per annum for 1996 for both Sterling Bank
and Houston National Bank. Other expenses increased $790,000 or 24.2% from 1995.
This increase was primarily attributable to an increase in expenditures for
marketing and advertising.

Management continually monitors overhead expenses. A key measure used to monitor
the Company's progress in controlling overhead expenses is the overhead ratio.
The overhead ratio is the Company's noninterest expenses, divided by the sum of
net interest income and noninterest income, exclusive of non-recurring expenses
related to the First Houston merger.
This ratio was 63.4%, 63.5%, and 66.2% for 1997, 1996, and 1995, respectively.

INCOME TAXES

The Company provided $6.6 million for federal income taxes for 1997, $5.1
million for 1996, and $4.4 million for 1995. The effective tax rates for 1997,
1996, and 1995 were 33.5%, 31.4%, and 31.3%, respectively.

FINANCIAL CONDITION

LOAN PORTFOLIO

At December 31, 1997, loans, excluding mortgage and student loans held for
resale in the amounts of $70.2 million in 1997 and $41.0 million in 1996, were
$667.9 million, an increase of $154.6 million or 30.1% over loans at December
31, 1996 of $513.4 million, as loan demand remained strong. During 1996, loans
increased $80.0 million, or 18.5%, from $433.3 million at December 31, 1995, to
$513.4 million at December 31, 1996.

At December 31, 1997, total loans were 72.2% of deposits and 62.4% of total
assets. At December 31, 1996, total loans were 66.0% of deposits and 60.1% of
total assets.

of December 31, excluding loans held for sale (in thousands):

</TABLE>

The primary  focus of the Bank is on commercial loans and owner-occupied
real estate loans to local businesses with annual sales ranging from $300,000 to
$30 million. Typically, the Bank's customers have financing requirements between
$100,000 and $500,000. The primary lending focus of the Bank has been on
commercial loans and owner-occupied real estate loans to local businesses.
Although the Bank's legal lending



                                       17
<PAGE>   18

limit was $12.0 million, at December 31, 1997, the Bank has not maintained
exposure greater than $7.0 million on any relationship.

The Bank makes commercial loans primarily to small and medium-sized businesses
and to professionals. The Bank offers a variety of commercial loan products
including revolving lines of credit, letters of credit, working capital loans,
and loans to finance accounts receivable, inventory and equipment. Typically,
the Bank's commercial loans have floating rates of interest, are for varying
terms (generally not exceeding three years), are personally guaranteed by the
borrower's owner and are secured by accounts receivable, inventory and/or other
business assets. In addition to the commercial loans secured solely by non-real
estate business assets, the Bank makes commercial loans which are secured by
owner-occupied real estate, as well as other business assets.

In addition to commercial loans secured by real estate, the Bank makes
residential and, to a lesser extent, commercial mortgage loans to finance the
purchase of real property, generally real estate on which structures have
already been completed. The Bank's residential mortgage loans are secured by
first liens on the underlying real property, have fixed interest rates, and
generally amortize over a 15-year period with balloon payments due at the end of
three years. Upon the expiration of each three-year period, the Bank may, but is
not obligated to, renew the loan at the then current market rate for an
additional three-year period. These loans are limited generally to 80% of the
property value.

The Bank's commercial mortgage loans are secured by first liens on real estate,
typically have floating interest rates, and amortize over a 15-year period with
balloon payments due at the end of three years. In underwriting commercial
mortgage loans, consideration is given to the property's operating history,
future operating projections, current and projected occupancy, location and
physical condition. The underwriting analysis also includes credit checks,
appraisals, and a review of the financial condition of the borrower.

The Bank makes loans to finance the construction of residential and, to a lesser
extent, nonresidential properties, such as churches. Construction loans
generally are secured by first liens on real estate and have floating interest
rates. The Bank conducts periodic inspections, either directly or through an
architect or other agent, prior to approval of periodic draws on these loans.
Underwriting guidelines similar to those described above are also used in the
Bank's construction lending activities.

The Bank makes automobile, boat, home improvement and other loans to consumers.
These loans are primarily made to customers who have other relationships with
the Bank. In addition, the Bank began issuing consumer credit cards through the
Visa and MasterCard systems during 1995. These cards are primarily issued to
customers who have other relationships with the Bank and excellent credit
histories. As of December 31, 1997 and 1996, the Bank had outstanding credit
card balances of $3.2 million and $2.1 million, respectively.

The strong 1997 loan demand created by the Bank's markets is an indicator of the
health in the Houston economy. The University of Houston's Center for Public
Policy projects an annual employment growth rate of 3% for the next five years,
a significant portion of which is expected to occur in the manufacturing, trade,
and services sectors. The Bank operates in a strong economic market, and expects
the underlying strength in the Houston area, at least during the near term, to
outperform the national economy. The Bank recognizes, however, that the effect
of national and international economic factors may temper the optimistic local
forecast and, therefore, the Bank imposes safeguards in its lending practices.
The Bank seeks to compete effectively in its chosen markets by consistent
application of its business strategy. See further discussion of "BUSINESS -
Supercommunity Bank Strategy" and "BUSINESS - Competition".

As of December 31, 1997, there was no concentration of loans to any one type of
industry exceeding 10% of total loans nor were there any loans classified as
highly-leveraged transactions.

RISK ELEMENTS

Nonperforming, past due, and restructured loans are fully or substantially
secured by assets, with any excess of loan balances over collateral values
specifically allocated in the allowance for credit losses. The Bank on an
ongoing basis receives updated appraisals on loans secured by real estate,
particularly those categorized as nonperforming loans and potential problem
loans. In those instances where updated appraisals reflect reduced



                                       18
<PAGE>   19

collateral values, an evaluation of the borrower's overall financial condition
is made to determine the need, if any, for possible writedowns or appropriate
additions to the allowance for credit losses.

The Bank defines potential problem loans as those loans not classified as
nonperforming, but where information known by management indicates serious doubt
that the borrower will be able to comply with the present payment terms.
Management identifies these loans through its continuous loan review process and
classifies potential problem loans as those loans graded as substandard,
doubtful, or loss, excluding all nonperforming loans.

The Bank had no material foreign loans outstanding or loan concentrations for
the years ended December 31, 1993, through 1997. The Bank, however, continues to
monitor the potential risk of foreign borrowers and concentrations of credit.

ALLOWANCE FOR CREDIT LOSSES

The Bank has several procedures in place to assist in maintaining the overall
quality of its loan portfolios. The Bank has established underwriting guidelines
to be followed by its bank offices. The Bank also monitors its delinquency
levels for any negative or adverse trends and particularly monitors credits
which have total exposure of $50,000 or more. However, there can be no assurance
that the Bank's loan portfolios will not become subject to increasing pressures
from deteriorating borrower creditworthiness due to general economic conditions.

The allowance for credit losses is a reserve established through charges to
earnings in the form of a provision for credit losses. Based on an evaluation of
the loan portfolios, management presents a quarterly review of the allowance for
credit losses to the Bank's Board of Directors, indicating any changes in the
allowance since the last review and any recommendations as to adjustments in the
allowance. In making its evaluation, management considers the industry
diversification of the Bank's commercial loan portfolio and the effect of
changes in the local real estate market on collateral values. The Bank also
considers the results of recent regulatory examinations. The Bank continues to
monitor the effects of current economic indicators and their probable impact on
borrowers, the amount of charge-offs for the period, the amount of
non-performing loans and related collateral security. The Bank monitors the loan
portfolio through its internal loan review department and obtains an annual loan
review by independent consultants. Charge-offs occur when loans are deemed to be
uncollectible.

The Bank follows a loan review program to evaluate the credit risk in the
commercial loan portfolio for substantially all commercial loans and real estate
loans. Through the loan review process, the Bank maintains an internally
classified loan list which, along with the delinquency list of loans, helps
management assess the overall quality of the loan portfolios and the adequacy of
the allowance for credit losses. Loans classified as "substandard" are those
loans with clear and defined weaknesses such as highly leveraged positions,
unfavorable financial ratios, uncertain repayment sources or poor financial
condition, which may jeopardize recoverability of the debt.

Loans classified as "doubtful" are those loans which have characteristics
similar to substandard accounts but with an increased risk that a loss may
occur, or at least a portion of the loan may require a charge-off if liquidated
at present. Although loans classified as substandard do not duplicate loans
classified as doubtful, both substandard and doubtful loans include some loans
that are delinquent at least 30 days or on nonaccrual status. Loans classified
as "loss" are those loans which are in the process of being charged off.

At December 31, 1997, substandard loans totaled $16.2 million, of which $3.7
million were loans designated as delinquent or nonaccrual; and doubtful loans
totaled $841 thousand of which $190 thousand were designated as delinquent or
nonaccrual.

In addition to the internally classified loan list and delinquency list of
loans, the Bank maintains a separate "watch list" which further aids the Bank in
monitoring loan portfolios. Watch list loans show warning elements where the
present status portrays one or more deficiencies that require attention in the
short run or where pertinent ratios of the loan account have weakened to a point
where more frequent monitoring is warranted. These loans do not have all the
characteristics of a classified loan (substandard or doubtful) but do show
weakened elements as compared with those of a satisfactory credit. The Bank
reviews these loans to assist in assessing the adequacy of the allowance for
credit losses. As of December 31, 1997 and 1996, none of the watch list loans
were designated as delinquent and there were none on nonaccrual. Approximately
99% of the loans on the watch list are current and paying in accordance with
loan terms as of December 31, 1997. As of December 31, 1997, watch list loans
totaled $9.7 million.

In order to determine the adequacy of the allowance for credit losses,
management considers the risk classification or delinquency status of loans and
other factors. Management also establishes specific allowances for credits which
management believes require reserves greater than those allocated according to
their classification or delinquent status. An unallocated allowance is also
established based on the Bank's historical charge-off experience. The Bank
currently charges against its operations a provision for credit losses equal to
an amount necessary to adjust the allowance to a level determined to be adequate
to absorb losses.

DEPOSITS

The Bank's lending and investing activities are funded almost entirely by core
deposits, approximately 78.0% of which are demand and savings deposits. Average
noninterest-bearing deposits for 1997 were $282.3 million



                                       22
<PAGE>   23

as compared to $222.7 million for 1996, an increase of $59.6 million or 26.7%
over 1996. Deposits grew due to a combination of same location growth and the
opening of three new locations in 1996 and 1997. Approximately 30.9% of average
1997 deposits were noninterest bearing as compared to 30.2% in 1996. The Bank
does not accept brokered deposits.

The Bank's average total deposits for 1997 were $913.4 million, or $175.6
million and 23.8% over average total deposits during 1996 which were $737.8
million, and increased $119.7 million, or 19.4% from average total deposits of
$618.1 million during 1995. The Bank's total deposits at December 31, 1997, were
$1.0 billion, up $181.9 million or 21.7% over total deposits of $840.3 million
at year-end 1996. Deposit growth continues to be concentrated primarily in core
deposits, consisting of all deposits other than retail and public fund
certificates of deposit in excess of $100,000.

The average balances and weighted average rates paid on deposits for each of the
years ended December 31, 1997, 1996, and 1995 are presented below (in

The Bank's time deposits of $100,000 or more have consistently shown a pattern
of renewal similar to that for deposits of less than $100,000. See Note I of the
consolidated financial statements for maturities of certificates of deposits of
$100,000 or more.

BORROWINGS

Deposits are the primary source of funds for the Bank's lending and investment
activities and for its general business purposes. Occasionally, the Bank obtains
additional funds from the Federal Home Loan Bank and correspondent banks. The
Bank has an available line of credit with the Federal Home Loan Bank of Dallas
which allows the Bank to borrow on a collateralized basis at a fixed rate for a
period from one to thirty-five days. At December 31, 1997, the Bank had $25
million borrowed under this line of credit. This line was repaid during the
first week of January 1998.

In connection with the acquisition of Enterprise in 1993 and the merger with
Guardian in 1994, the Company entered into a loan agreement with a bank (the
"lending bank") which committed $6,600,000 for the funding of the acquisition of
Enterprise and $1,400,000 for the merger with Guardian. The Company prepaid the
loan in full during 1997.

In February 1991, the Company issued and sold $2,850,000 in aggregate principal
amount of interest-bearing debentures (the "debentures") in denominations of
$50,000 bearing interest at rates ranging from 8.6% to 10.5%, depending on the
maturity date. All remaining debentures matured during the year ended December
31, 1996.

In June 1997, the Company formed Sterling Bancshares Capital Trust I, a trust
formed under the laws of the State of Delaware (the "Trust"). The Company is the
owner of the entire beneficial interest represented by common securities of the
Trust. The Trust issued $28,750,000 of 9.28% Trust Preferred Securities and
invested the proceeds thereof in the 9.28% Junior Subordinated Deferrable
Interest Debentures (the "Junior Subordinated Debentures") issued by the
Company. The Junior Subordinated Debentures will mature on June 6, 2027, which
date may be shortened to a date not earlier than June 6, 2002 if certain
conditions are met (including the Company having received prior approval of the
Federal Reserve and any other required regulatory approvals). The Trust
Preferred Securities will be subject to mandatory redemption in a like amount



                                       23
<PAGE>   24

contemporaneously with the optional prepayment of the Junior Subordinated
Debentures by the Company. The Junior Subordinated Debentures may be prepaid
upon the occurrence and continuation of certain events including a change in the
tax status or regulatory capital treatment of the Trust Preferred Securities. In
each case, redemption will be made at a price equal to 100% of the face amount
of the Trust Preferred Securities, plus the accrued and unpaid distributions
thereon through the redemption date.

INTEREST RATE SENSITIVITY AND LIQUIDITY

The Company manages its interest rate risk through structuring the balance sheet
portfolios to maximize net interest income while maintaining an acceptable level
of risk to changes in market interest rates. This process requires a balance
between profitability, liquidity, and interest rate risk.

To effectively measure and manage interest rate risk, the Company uses
simulation analysis to determine the impact on net interest income of changes in
interest rates under various interest rate scenarios, balance sheet trends, and
strategies. From these simulations, interest rate risk is quantified and
appropriate strategies are developed and implemented. The overall interest rate
risk position and strategies are reviewed by Management, the Asset/Liability
Management Committee and the Company's Board of Directors on an ongoing basis.

The following table presents an analysis of the sensitivity inherent in the
Company's net interest income and market value of portfolio equity. The interest
rate scenarios presented in the table include interest rates at December 31,
1997 and as adjusted by instantaneous rate changes upward and downward of up to
200 basis points. Each rate scenario reflects unique prepayment and repricing
assumptions. Since there are limitations inherent in any methodology used to
estimate the exposure to changes in market interest rates, this analysis is not
intended to be a forecast of the actual effect of a change in market interest
rates on the Company. The market value sensitivity analysis presented includes
assumptions that (i) the composition of the Company's interest sensitive assets
and liabilities existing at fiscal year end will remain constant over the
measurement period; and (ii) that changes in market rates are parallel and
instantaneous across the yield curve regardless of duration or repricing
characteristics of specific assets or liabilities. Further, the analysis does
not contemplate any actions that the Company might undertake in response to
changes in market interest rates. Accordingly, this analysis is not intended and
does not provide a precise forecast of the effect actual changes in market rates
will have on the Company.

</TABLE>


An interest rate sensitive asset or liability is one that, within a defined time
period, either matures or experiences an interest rate change in line with
general market interest rates. The management of interest rate risk is performed
by analyzing the maturity and repricing relationships between interest-earning
assets and interest-bearing liabilities at specific points in time ("GAP") and
by analyzing the effects of interest rate changes on net interest income over
specific periods of time by projecting the performance of the mix of assets and
liabilities in varied interest rate environments. Interest rate sensitivity
reflects the potential effect on net interest income of a movement in interest
rates. A company is considered to be asset sensitive, or having a positive GAP,
when the amount of its interest-earning assets maturing or repricing within a
given period exceeds the amount of its interest-bearing liabilities also
maturing or repricing within that time period. Conversely, a company is
considered to be liability sensitive, or having a negative GAP, when the amount
of its interest-bearing liabilities maturing or repricing within a given period
exceeds the amount of its interest-earning assets also maturing or repricing
within that time period. During a period of rising interest rates, a negative
GAP would tend to affect adversely net interest income, while a positive GAP
would tend to result in an



                                       24
<PAGE>   25

increase in net interest income. During a period of falling interest rates, a
negative GAP would tend to result in an increase in net interest income, while a
positive GAP would tend to affect net interest income adversely. When analyzing
its GAP position, the Company emphasizes the next twelve month period.

The following table sets forth the expected maturity and repricing
characteristics of the Company's interest earning assets and interest bearing
liabilities as of December 31, 1997:

Shortcomings are inherent in any GAP analysis since certain assets and
liabilities may not re-price proportionally as interest rates change.
Consequently, the Company's management has begun to utilize an interest rate
risk simulation model to increase its ability to monitor and forecast the effect
of various interest rate environments on earnings and its net capital position.

Liquidity involves the Company's ability to raise funds to support asset growth
or reduce assets to meet deposit withdrawals and other payment obligations, to
maintain reserve requirements and otherwise to operate the Company on an ongoing
basis. In recent years, the Company's liquidity needs have primarily been met by
growth in core deposits, as previously discussed. Although access to purchased
funds from correspondent banks is available and has been utilized on occasion to
take advantage of investment opportunities, the Company does not generally rely
on these external funding sources. Generally, the cash and federal funds sold
position, supplemented by amortizing investment and loan portfolios, have
created an adequate liquidity position.

CAPITAL RESOURCES

At December 31, 1997, shareholders' equity totaled $80.0 million or 6.8% of
total assets, as compared to $67.0 million and 7.3% of total assets at December
31, 1996.

Bank regulatory authorities in the United States have issued risk-based capital
standards by which all bank holding companies and banks will be evaluated in
terms of capital adequacy. These guidelines relate a banking



                                       25
<PAGE>   26

company's capital to the risk profile of its assets. Tier 1 capital includes
common stockholders' equity, minority interest in consolidated subsidiaries, and
qualifying perpetual preferred stock together with related surpluses and
retained earnings. Tier 2 capital may be comprised of limited life preferred
stock, qualifying debt instruments, and the reserves for credit losses.

Banking regulators have also issued leverage ratio requirements. The leverage
ratio requirement is measured as the ratio of Tier 1 capital to adjusted assets.
See Note S to the Company's consolidated financial statements for further
discussion of the Company's and the Bank's regulatory capital requirements.

The Bank's capital levels at December 31, 1997 and 1996 qualifies it as
"well-capitalized," the highest of five tiers under applicable regulatory
definitions.

CONTINGENCIES AND UNCERTAINTIES--YEAR 2000

The Company developed and commenced implementation of a comprehensive plan in
April 1997 to ensure that its operational and financial systems will not be
adversely affected by Year 2000 software programming errors. Prior to formal
adoption of the Year 2000 plan, in October 1995 a three-year technology plan was
approved jointly by the boards of directors of the Company and the Bank. The
technology plan represented a comprehensive program to reengineer and redesign
the Bank's entire information systems, telecommunications and technology
infrastructure. Pursuant to this plan, the Company spent more than $3 million
during 1996 and 1997 to upgrade its core data processing, network
communications, and teller systems. As part of the selection process for new
systems and software applications, each system and application upgrade was
evaluated for Year 2000 compliance.

Implementation of the Company's Year 2000 Plan is well underway. A Year 2000
project management team has been formed with representation from all functional
and operational areas of the Bank. Four full-time employees have been dedicated
the project team with the requisite level of experience and knowledge to ensure
that all mission critical applications are Year 2000 compliant. The boards of
directors of the Company and the Bank are cognizant of the Year 2000 business
risk, have formally reviewed and approved the Year 2000 plan, and have committed
the necessary resources for successful completion of the project. Senior
management is actively involved in the Year 2000 compliance effort and will
closely monitor the effort and provide regular status reports to the boards of
directors. All employees have been required to attend training programs
regarding the Year 2000 issue and the Company's plan.

The Year 2000 project team has conducted a complete inventory of all systems,
applications and lines of business to assess and prioritize the potential risks
of any Year 2000 errors to the integrity of the Bank's systems and applications,
the accuracy of data and critical information, and the operational stability of
all management information systems and bank office environments. The software
applications that support the Company's systems are provided primarily through
third party vendors and service bureaus. All third party providers must certify
and, as necessary, demonstrate that their applications, systems and products are
presently, or will be by December 31, 1998, Year 2000 compliant. Depending upon
the risk priorities identified through the inventory and assessment phase, the
Company will test all mission critical applications prior to October 31, 1998,
with follow-up testing to be conducted throughout 1999. As part of the testing
process, the Company will construct a stand alone network to safely test all
networked systems and applications. If any mission critical applications or
systems are deemed through the testing and validation phases not to be Year 2000
compliant, all appropriate renovations and upgrades will be made with such
upgraded applications and products being retested in early 1999. Since the
Company has already incurred the expense of upgrading its core data processing,
network communications and teller systems, management does not expect that the
costs associated with implementation of the Year 2000 plan, including any
required renovations, will have a materially adverse effect on the Company's
financial condition, results of operations or liquidity.

INDEPENDENT AUDITORS' REPORT


To the Board of Directors and Shareholders of
    Sterling Bancshares, Inc.
Houston, Texas

We have audited the accompanying consolidated balance sheets of Sterling
Bancshares, Inc. and subsidiaries (the "Company") as of December 31, 1997 and
1996, and the related consolidated statements of income, shareholders' equity
and cash flows for each of the three years in the period ended December 31,
1997. These financial statements are the responsibility of the Company'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
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, such consolidated financial statements present fairly, in all
material respects, the consolidated financial position of Sterling Bancshares,
Inc. and subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.

STERLING BANCSHARES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
FOR THE YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
- --------------------------------------------------------------------------------


A.    ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES

      NATURE OF OPERATIONS - Sterling Bancshares, Inc., ("Bancshares"), is a
      bank holding company headquartered in Houston, Texas that provides retail
      and commercial banking services through Sterling Bank (the "Bank"), its
      Texas-chartered bank subsidiary. The Bank provides a broad line of
      financial products and services to small and medium-sized businesses and
      consumers through its sixteen community banking offices in Harris County.

      SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES - The accounting
      and reporting policies of Bancshares conform to generally accepted
      accounting principles and the prevailing practices within the banking
      industry. A summary of significant accounting policies follows:

      BASIS OF PRESENTATION - The consolidated financial statements include the
      accounts of Bancshares and its wholly owned subsidiaries, Sterling
      Bancorporation, Inc. ("Bancorp"), Sterling Bancshares Capital Trust I and
      the Bank, hereafter collectively referred to as the "Company." All
      material intercompany transactions 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 in the
      financial statements. Actual results could differ from those estimates.

      INVESTMENT SECURITIES - Investment securities held to maturity are carried
      at cost, adjusted for the amortization of premiums and the accretion of
      discounts. Management has the positive intent and the Company has the
      ability to hold these assets until their estimated maturities. Under
      certain circumstances (including the deterioration of the issuer's
      creditworthiness or a change in tax law or statutory or regulatory
      requirements), securities may be sold or transferred to another portfolio.

      Investment securities available-for-sale are carried at fair value.
      Unrealized gains and losses are excluded from earnings and reported net of
      tax, as a separate component of shareholders' equity until realized.
      Securities within the available-for-sale portfolio may be used as part of
      the Company's asset and liability management strategy and may be sold in
      response to changes in interest rate risk, prepayment risk or other
      factors.

      Premiums and discounts are amortized and accreted to operations using the
      level-yield method of accounting, adjusted for prepayments as applicable.
      The specific identification method of accounting is used to compute gains
      or losses on the sales of these assets.

      INVESTMENT IN STERLING CAPITAL MORTGAGE COMPANY - In September 1996, the
      Bank acquired a 40% equity and 44% voting interest in Sterling Capital
      Mortgage Company, ("SCMC"), an originator and servicer of single family
      residential mortgage loans headquartered in Houston, Texas. The Bank
      accounts for its investment using the equity method of accounting. Under
      the equity method, the original investment is recorded at cost and is
      adjusted periodically to recognize the Bank's share



                                       38
<PAGE>   39

      of earnings or losses after the date of acquisition. Dividends received
      reduce the basis of the investment.

      LOANS HELD FOR SALE - Loans originated and intended for sale in the
      secondary market are carried at the lower of cost or market value in the
      aggregate. Net unrealized losses are recognized in a valuation allowance
      by charges to income. There were no net unrealized losses charged to
      income during 1997, 1996 or 1995.

      LOANS - Loans are stated at the principal amount outstanding, net of
      unearned discount. Unearned discount relates principally to consumer
      installment loans. The related interest income for installment loans is
      recognized principally by the "sum of the months' digits" method, which
      records interest in proportion to the declining outstanding balances of
      the loans. This method approximates the interest method. For other loans,
      such income is recognized using the simple interest method.

      Impaired loans, with the exception of groups of smaller-balance
      homogeneous loans that are collectively evaluated for impairment, are
      defined as loans for which, based on current information and events, it is
      probable that a creditor will be unable to collect all amounts due, both
      interest and principal, according to the contractual terms of the loan
      agreement. The allowance for credit losses related to impaired loans is
      determined based on the present value of expected cash flows discounted at
      the loan's effective interest rate or, as a practical expedient, the
      loan's observable market price or the fair value of the collateral if the
      loan is collateral dependent.

      NONACCRUAL, PAST-DUE AND RESTRUCTURED LOANS - Included in this loan
      category are loans which have been categorized by management as nonaccrual
      because collection of interest is doubtful and loans which have been
      restructured to provide a reduction in the interest rate below the current
      market rate or a deferral of interest or principal payments.

      When the payment of principal or interest on a loan is delinquent for 90
      days, or earlier in some cases, the loan is placed on nonaccrual status
      unless the loan is in the process of collection and the underlying
      collateral fully supports the carrying value of the loan. If the decision
      is made to continue accruing interest on the loan, periodic reviews are
      made to evaluate the appropriateness of the accruing status of the loan.
      When a loan is placed on nonaccrual status, interest accrued and
      uncollected during the current year prior to the judgment of
      noncollectibility is charged to operations. Interest accrued and
      uncollected during prior periods is charged to the allowance for credit
      losses. Generally, any payments received on nonaccrual loans are applied
      first to outstanding loan amounts and next to the recovery of charged-off
      loan amounts. Any excess is treated as a recovery of lost interest.

      Restructured loans are those loans for which concessions in terms have
      been granted because of a borrower's financial difficulty. Interest is
      generally accrued on such loans in accordance with the new terms.

      ALLOWANCE FOR CREDIT LOSSES - The allowance for credit losses is a
      valuation allowance available for losses incurred on loans. All losses are
      charged to the allowance when the loss actually occurs or when a
      determination is made that a probable loss has occurred. Recoveries are
      credited to the allowance at the time of recovery.

      Throughout the year, management estimates the probable level of losses to
      determine whether the allowance for credit losses is adequate to absorb
      losses in the existing portfolio. Based on these



                                       39
<PAGE>   40

      estimates, an amount is charged to the provision for credit losses and
      credited to the allowance for credit losses in order to adjust the
      allowance to a level determined to be adequate to absorb losses.

      Management's judgment as to the level of losses on existing loans involves
      the consideration of current and anticipated economic conditions and their
      potential effects on specific borrowers; an evaluation of the existing
      relationships among loans, potential credit losses and the present level
      of the allowance; results of examinations of the loan portfolio by
      regulatory agencies; and management's internal review of the loan
      portfolio. In determining the collectibility of certain loans, management
      also considers the fair value of any underlying collateral. The amounts
      ultimately realized may differ from the carrying value of these assets
      because of economic, operating or other conditions beyond the Company's
      control.

      It should be understood that estimates of credit losses involve an
      exercise of judgment. While it is reasonably possible that in the near
      term the Company may sustain losses which are substantial relative to the
      allowance for credit losses, it is the judgment of management that the
      allowance for credit losses reflected in the consolidated balance sheets
      is adequate to absorb estimated losses that exist in the current loan
      portfolio.

      PREMISES AND EQUIPMENT - Land is carried at cost. Premises and equipment
      are carried at cost, less accumulated depreciation and amortization.
      Depreciation expense is computed principally using the straight-line
      method over the estimated useful lives of the assets. Leasehold
      improvements are amortized using the straight-line method over the periods
      of the leases or the estimated useful lives, whichever is shorter.

      AMORTIZATION OF GOODWILL - Goodwill is amortized using the straight-line
      method over a period of 10 to 25 years. Management periodically performs
      an evaluation of whether any impairment of goodwill has occurred. If any
      such impairment is identified, a write-down of the goodwill is recorded.
      There were no such write-downs recorded during 1997, 1996 or 1995.

      REAL ESTATE ACQUIRED BY FORECLOSURE - The Bank records real estate
      acquired by foreclosure at fair value less estimated costs to sell.
      Adjustments are made to reflect declines in value subsequent to
      acquisition, if any, below the recorded amounts. Required developmental
      costs associated with foreclosed property under construction are
      capitalized and considered in determining the fair value of the property.
      Real estate and other property acquired in lieu of loan balances are
      included in the accompanying consolidated balance sheets. Operating
      expenses of such properties, net of related income, and gains and losses
      on their disposition are included in noninterest expenses.

      INCOME TAXES - Bancshares files a consolidated federal income tax return
      with its subsidiaries. Each computes income taxes as if it filed a
      separate return and remits to, or is reimbursed by Bancshares based on the
      portion of taxes currently due or refundable.

      Deferred income taxes are accounted for by applying statutory tax rates in
      effect at the balance sheet date to differences between the book basis and
      the tax basis of assets and liabilities. The resulting deferred tax assets
      and liabilities are adjusted to reflect changes in enacted tax laws or
      rates.

      Realization of net deferred tax assets is dependent on generating
      sufficient future taxable income. Although realization is not assured,
      management believes it is more likely than not that all of the net
      deferred tax assets will be realized. The amount of the net deferred tax
      asset considered



                                       40
<PAGE>   41

      realizable, however, could be reduced in the near term if estimates of
      future taxable income are reduced.

      STOCK-BASED COMPENSATION - On January 1, 1996, the Company adopted
      Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting
      for Stock-based Compensation". This statement defines a fair value-based
      method of accounting for an employee stock option or similar equity
      instrument and encourages adoption of that method for all employee stock
      compensation plans. However, it also allows an entity to continue to
      measure compensation costs for those plans using the intrinsic value-based
      method currently being followed by the Company and make pro forma
      disclosures of net income and earnings per common share ("EPS") under the
      fair value-based method of accounting. The Company will continue
      accounting for stock-based employee compensation plans using the intrinsic
      value-based method and is disclosing pro forma information as prescribed
      by SFAS No. 123. See Note N.

      PROFIT SHARING PLAN - The Company has a profit sharing plan which covers
      substantially all employees. Contributions are accrued and funded
      currently.

      STATEMENTS OF CASH FLOWS - For purposes of the statements of cash flows,
      cash and cash equivalents are defined as cash and due from banks and
      federal funds sold. Generally, federal funds are sold for one-day periods.

      EARNINGS PER SHARE - The Company adopted SFAS No. 128, "Earnings per
      Share" in 1997. All previously reported EPS amounts have been restated.
      The restated amounts are not materially different from those previously
      reported.

      Basic earnings per share is computed using the weighted average number of
      shares outstanding. Diluted earnings per share is computed using the
      weighted average number of shares outstanding adjusted for the incremental
      shares issuable upon conversion of preferred stock and issuable upon
      exercise of outstanding stock options.

      RECLASSIFICATIONS - Certain reclassifications have been made to prior
      years' amounts to conform them to current year presentation. All
      reclassifications have been applied consistently for the periods
      presented.

      RECENT ACCOUNTING STANDARDS - SFAS No. 130, "Reporting Comprehensive
      Income" requires that all components of comprehensive income and total
      comprehensive income be reported on one of the following: (1) the
      statement of income, (2) the statement of stockholders' equity, or (3) a
      separate statement of comprehensive income. Comprehensive income is
      comprised of net income and all changes to stockholders' equity, except
      those due to investments by owners (changes in capital surplus) and
      distributions to owners (dividends). This statement is effective for
      fiscal years beginning after December 15, 1997. The implementation of SFAS
      No. 130 should have no material impact on the Company's consolidated
      financial statements.

      SFAS No. 131, "Disclosure About Segments of an Enterprise and Related
      Information" requires public companies to report certain information about
      their operating segments in their annual financial statements and
      quarterly reports issued to shareholders. It also requires public
      companies to report certain information about their products and services,
      the geographic areas in which they operate, and their major customers.
      This statement is effective for fiscal years beginning after December 15,
      1997. Implementation of SFAS No. 131 should have no material effect on the
      Company's consolidated financial statements.

B.    ACQUISITIONS

      On September 30 , 1997, the Company acquired First Houston Bancshares,
      Inc. ("First Houston") in exchange for 1,686,014 shares of the Company's
      common stock for First Houston's outstanding common and preferred stock.
      The transaction has been accounted for as a pooling of interests and
      previously issued financial statements have been restated. There were no
      material adjustments to the net assets of First Houston as a result of
      adopting the same accounting practices as Sterling Bancshares, Inc. and
      its subsidiaries. At September 30, 1997, First Houston had total assets of
      approximately $135 million and total deposits of approximately $125
      million. The following table reflects the results of operations of the
      Company as originally reported and the combined amounts after the pooling
      of interests:

      fixed term for a period generally not exceeding one week. At December 31,
      1997, the Bank had $25,000,000, bearing an interest rate of 6.30%,
      borrowed under this line of credit, with a term of one week.

K.    NOTES PAYABLE

      In connection with the acquisition of Enterprise Bank ("Enterprise") in
      1993 and the merger with Guardian Bancshares, Inc. ("Guardian") in 1994,
      the Company entered into a loan agreement with a bank (the "lending bank")
      which committed $6,600,000 for the funding of the acquisition of
      Enterprise and $1,400,000 for the merger with Guardian. The Company
      prepaid the loan in full during 1997.

      In February 1991, the Company issued and sold $2,850,000 in aggregate
      principal amount of interest-bearing senior debentures (the "debentures")
      in denominations of $50,000 bearing interest at rates ranging from 8.6% to
      10.5%, depending on the maturity date. All remaining debentures matured
      during the year ended December 31, 1996.

L.    TRUST PREFERRED SECURITIES

      In June 1997, the Company formed Sterling Bancshares Capital Trust I, a
      trust formed under the laws of the State of Delaware (the "Trust"). The
      Company is the owner of the entire beneficial interest represented by
      common securities of the Trust. The Trust issued $28,750,000 of 9.28%
      Trust Preferred Securities and invested the proceeds thereof in the 9.28%
      Junior Subordinated Deferrable Interest Debentures (the "Junior
      Subordinated Debentures") issued by the Company. The Junior Subordinated
      Debentures will mature on June 6, 2027, which date may be shortened to a
      date not earlier than June 6, 2002 if certain conditions are met
      (including the Company having received prior approval of the Federal
      Reserve and any other required regulatory approvals). The Trust Preferred
      Securities will be subject to mandatory redemption in a like amount
      contemporaneously with the optional prepayment of the Junior Subordinated
      Debentures by the Company. The Junior Subordinated Debentures may be
      prepaid upon the occurrence and continuation of certain events including a
      change in the tax status or regulatory capital treatment of the Trust
      Preferred Securities. In each case, redemption will be made at a price
      equal to 100% of the face amount of the Trust Preferred Securities, plus
      the accrued and unpaid distributions thereon through the redemption date.

N.    EMPLOYEE BENEFITS

      PROFIT SHARING PLAN - The Company's profit sharing plan includes
      substantially all employees. Contributions to the plan are made at the
      discretion of the Board of Directors but generally equal up to 10% of the
      Company's pretax income, subject to maximum contributions to each
      employee's account under applicable sections of the IRS code. Employee
      contributions to 401(k) plan accounts are optional. Beginning in 1997, the
      Company matched 50 percent of the employee's contribution, up to 6 percent
      of the employee's base pay. Profit sharing contributions are accrued and
      funded currently. Total profit sharing expense for 1997, 1996 and 1995 was
      approximately $1,702,000, $1,711,000, and $1,443,000, respectively.

      STOCK-BASED COMPENSATION - During April 1994, the Company adopted the
      "1994 Stock Incentive Plan (the "Stock Plan"). The Stock Plan provides for
      a maximum of 1,182,000 shares of the Company's common stock to be issued
      with 1,098,000 shares reserved for options and 84,000 shares to be
      reserved for issuance as performance shares. No options or performance
      shares may be granted after April 2004. The options are to be issued at
      the fair market value at the date of grant, and, accordingly, such options
      are noncompensatory. These options have been granted to officers at stock
      prices determined by the Compensation Committee of the Board of Directors
      which approximate the fair market value of the common stock at the date of
      grant and generally vest ratably over a four-year period. Options granted
      under the plan must be exercised not later than ten years from the date of
      grant. Compensation expense is recognized for performance shares issued. A
      total of 950, 1,950 and 5,625 performance shares were awarded under the
      Stock Plan during 1997, 1996 and 1995, respectively.

      If compensation cost for the Company's stock-based compensation plan had
      been determined based on the fair value at the grant dates for awards,
      there would have been no material impact on the Company's net income or
      diluted earnings per share.

      The fair value of options at date of grant was estimated using the
      Black-Scholes option pricing model with the following weighted-average
      assumptions:

      STOCK PURCHASE PLAN - The Company offers the 1994 Employee Stock Purchase
      Plan (the "Purchase Plan"), which is a compensatory benefit plan, to all
      employees who are employed for more than 20 hours per week and meet
      minimum length-of-service requirements of three months. The Purchase Plan
      provides for an aggregate of 450,000 shares of the Company's common stock
      to be issued under the Plan with no more than 45,000 shares available
      during any annual offering. The purchase price for shares available under
      the Purchase Plan is equal to the fair market value on the date of the
      offering. During 1997 and 1996, 3,627 and 17,363 shares, respectively,
      were purchased and 17,866 and 6,228 shares, respectively, were subscribed
      for through payroll deduction for a maximum of two years. Shares are
      issued upon full payment.

      PREFERRED STOCK - The Company's Board of Directors has authorized the
      issuance of up to 150,000 shares of convertible preferred stock in each of
      four series designated as Series A, Series B, Series C, and Series D. The
      Series A shares were offered and sold pursuant to a Confidential Private
      Placement Memorandum in conjunction with the opening of the new Cypress
      office of Sterling Bank. The offering terminated October 20, 1995,
      resulting in the issuance of 49,500 shares of preferred stock, which are
      convertible into a maximum of 183,769 shares of the Company's common stock
      after the February 20, 1998 stock split. The conversion ratio is dependent
      upon the Cypress office meeting certain performance goals.

      In conjunction with the opening of the Upper Kirby office in August 1996,
      the Series B shares were offered and sold pursuant to a Confidential
      Private Placement Memorandum. The offering terminated October 1, 1996,
      resulting in the issuance of 38,880 shares of preferred stock, which are
      convertible into 109,350 shares of the Company's common stock after the
      February 20, 1998 stock split. The Upper Kirby office has met the
      requisite performance goal such that the Series B shares will convert at
      the maximum ratio on August 12, 1998.

      convertible into a maximum of 72,188 shares of common stock after the
      February 20, 1998 stock split. The conversion ratio is dependent on the
      Fountainview office meeting certain deposit growth goals.

      On October 21, 1996, the Company's Board of Directors designated a series
      of convertible preferred stock, Series D, and authorized the issuance of
      up to 150,000 shares of Series D shares. In conjunction with the opening
      of the Cypress Station office in January 1997, the Series D shares were
      offered and sold pursuant to a Confidential Private Placement Memorandum.
      The offering terminated on May 5, 1997, resulting in the issuance of
      50,233 shares of preferred stock, which are convertible into a maximum of
      94,187 shares of common stock after the February 20, 1998 stock split. The
      conversion ratio is dependent on the Cypress Station office meeting
      certain deposit growth goals.

      DIVIDEND-IN-KIND - On December 29, 1995, First Houston distributed its
      computer software service business to its shareholders through a transfer
      of 239,500 shares of $1 par value common stock, constituting all of the
      issued and outstanding shares of Altair. No gain or loss was recognized
      from the distribution, and the book value of Altair of $894,370 was
      eliminated against retained earnings. The financial position and results
      of operations of Altair were not material to the consolidated financial
      statements of the Company.

Q.    COMMITMENTS AND CONTINGENCIES

      LEASES - A summary as of December 31, 1997, of noncancelable future
      operating lease commitments follows (in thousands):

                                                  =======    
</TABLE>

      Rent expense under all noncancelable operating lease obligations, net of
      income from noncancelable subleases aggregated, was approximately
      $427,000, $319,000, and $266,000 for the years ended December 31, 1997,
      1996 and 1995, respectively.

      LITIGATION - The Company has been named as a defendant in various legal
      actions arising in the normal course of business. In the opinion of
      management, after reviewing such claims with outside counsel, resolution
      of such matters will not have a materially adverse impact on the
      consolidated financial statements.

R.    FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

      The Bank is a party to various financial instruments with off-balance
      sheet risk in the normal course of business to meet the financial needs of
      its customers. These financial instruments include commitments to extend
      credit and standby letters of credit. These instruments involve, to
      varying degrees, elements of credit and interest rate risk in excess of
      the amounts 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 is
      represented by the 


                                       52
<PAGE>   53

      contractual notional amount of these instruments. The Bank uses the same
      credit policies in making these commitments and conditional obligations as
      it does for on-balance sheet instruments.

      The following is a summary of the various financial instruments entered
      into by the Bank (in thousands):

<TABLE>

Financial instruments whose contract amount
   represents credit risk:
      Commitments to extend credit                        $102,688      $ 83,668
      Standby letters of credit                             10,296         6,634
      Mortgages sold with recourse                         150,652          --
</TABLE>

      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 fully drawn upon, the total
      commitment amounts disclosed above 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 considered necessary by the
      Bank upon extension of credit, is based on management's credit evaluation
      of the customer.

      Standby letters of credit are conditional commitments issued by the Bank
      to guarantee the performance of a customer to a third party. The credit
      risk to the Bank in issuing letters of credit is essentially the same as
      that involved in extending loan facilities to its customers.

S.    REGULATORY MATTERS

      CAPITAL REQUIREMENTS - The Company is subject to various regulatory
      capital requirements administered by the federal banking agencies. Any
      institution that fails to meet its minimum capital requirements is subject
      to actions by regulators that could have a direct material effect on its
      financial statements. Under the capital adequacy guidelines and the
      regulatory framework for prompt corrective action, the Bank must meet
      specific capital guidelines based on the Bank's assets, liabilities, and
      certain off-balance sheet items as calculated under regulatory accounting
      practices. The Company's capital amount and the Bank's classification
      under the regulatory framework for prompt corrective action are also
      subject to qualitative judgments by the regulators.

      To meet the capital adequacy requirements, the Company must maintain
      minimum capital amounts and ratios as defined in the regulations.
      Management believes, as of December 31, 1997 and 1996, that the Company
      met all capital adequacy requirements to which they are subject.

      As of December 31, 1997, the most recent notification categorized the Bank
      as "well capitalized" and there have been no events since that
      notification that management believes have changed the Bank's category. 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.

T.    DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL STATEMENTS

      Fair values were estimated by management as of December 31, 1997 and 1996,
      and required considerable judgment. Accordingly, the estimates presented
      herein are not necessarily indicative of the amounts the Company could
      realize in a current market exchange. The use of different market
      assumptions and/or estimation methodologies may have a material effect on
      the estimated fair values presented.

      The following methods and assumptions were used to estimate the fair value
      of cash and of financial instruments for which it is practicable to
      estimate that value:

      CASH AND SHORT-TERM INVESTMENTS - For short-term investments, the carrying
      amount is a reasonable estimate of fair value.


                                       54
<PAGE>   55

      INVESTMENT SECURITIES - For securities held as investment, fair value
      equals quoted market prices, if available. If a quoted market price is not
      available, fair value is estimated using quoted market prices for similar
      securities.

      LOANS HELD FOR SALE - For loans held for sale, fair value equals quoted
      market prices, if available. If a quoted market price is not available,
      the fair value is estimated by discounting the future cash flows using the
      current rates at which similar loans would be made to borrowers with
      similar credit ratings and for the same remaining maturities.

      LOAN RECEIVABLES - The fair value of loans is estimated by discounting the
      future cash flows using the current rates at which similar loans would be
      made to borrowers with similar credit ratings and for the same remaining
      maturities.

      DEPOSIT LIABILITIES - The fair value of demand deposits, savings accounts
      and certain money market deposits is the amount payable on demand at the
      reporting date. The fair value of certificates of deposit is estimated
      using the rates currently offered for deposits of similar remaining
      maturities.

      SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE AND OTHER BORROWINGS - The
      carrying amounts approximate fair value because these borrowings reprice
      at market rates generally within four days.

      NOTES PAYABLE - Rates currently available to the Company for debt with
      similar terms and remaining maturities are used to discount the future
      cash flows to estimate fair value of existing debt.

      COMMITMENTS TO EXTEND CREDIT, STANDBY LETTERS OF CREDIT AND FINANCIAL
      GUARANTEES WRITTEN - The fair value of commitments is estimated using the
      fees currently charged to enter into similar agreements, taking into
      account the remaining terms of the agreements and the present
      creditworthiness of the counterparties. For fixed-rate loan commitments,
      fair value also considers the difference between current levels of
      interest rates and the committed rates. The fair value of guarantees and
      letters of credit is based on fees currently charged for similar
      agreements or on the estimated cost to terminate them or otherwise settle
      the obligations with the counterparties at the reporting date.
