     COMPREHENSIVE INCOME

     Effective January 1, 1998, the Company has adopted Financial Accounting
Standards No. 130, Reporting Comprehensive Income, which requires the reporting
of comprehensive income in addition to net income from operations. Comprehensive
income is a more inclusive financial reporting methodology which includes
disclosure of certain financial information that historically has not been
recognized in the calculation of net earnings.

     The tax effects for components of comprehensive income are as follows:

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS


     Guaranty Bancshares, Inc. (the "Company") is a registered bank holding
company that derives substantially all of its revenues and income from the
operation of its subsidiary, Guaranty Bank (the "Bank").  The Bank is a full
service bank that provides a broad line of financial products and services to
small and medium-sized businesses and consumers through seven banking locations
in the Texas communities of Mount Pleasant (two offices), Bogata, Deport, Paris,
Talco and Texarkana.  The following Management's Discussion and Analysis of
Financial Condition and Results of Operations may contain certain forward-
looking statements regarding future financial condition, results of operations,
and the Company's business operations.  Such statements involve risks,
uncertainties and assumptions, including, but not limited to monetary policy and
general economic conditions in Texas and more specifically Northeast Texas, the
actions of competitors and customers, the success of the Company in implementing
its strategic plan, and the effects of regulatory restrictions imposed on banks
and bank holding companies generally.  Should one or more of these risks or
uncertainties materialize or should these underlying assumptions prove
incorrect, actual outcomes may vary materially from outcomes expected or
anticipated by the Company.

OVERVIEW

     Net earnings for the three months ended March 31, 1998 were $720,000 or
$0.28 per share compared to $438,000 or $0.17 per share for the three months
ended March 31, 1997, an increase of 64.4%. While aided by an increase in net
interest income, the improvement in net earnings was primarily the result of a
gain on the sale of $2.0 million in principal amount of mortgage loans that were
originally purchased in 1991 at a discount from the Resolution Trust
Corporation("RTC"). In March of 1998, the Company sold the mortgage loans at
par, which resulted in a gain of $444,000, net of $230,000 in taxes expensed as
a result of the sale. The Company did not have a gain from the sale of loans in
the first quarter of 1997. The gain on the sale of the loans in 1998 was
partially offset by an increase in the provision for loan losses from $20,000 in
the first quarter of 1997 to $370,000 in the first quarter of 1998 primarily as
the result of a $22.2 million or 15.9% increase in loans during the same time
period. Accordingly, after giving effect to these transactions, core earnings
for the period were $606,000 or $0.24 per share for the first quarter of 1998
compared to $438,000 or $0.17 per share for the first quarter of 1997, a 38.4%
increase.

     The quarter ended March 31, 1998 showed stable growth. Total loans
increased to $163.1 million at March 31, 1998 from $157.4 million at December
31, 1997, an increase of $5.7 million or 3.6%. Total assets were $247.5 million
at March 31, 1998 compared with $244.2 million at December 31, 1997. The
increase in total assets resulted mainly from an increase in total deposits to
$225.2 million at March 31, 1998 from $223.0 million at December 31, 1997, an
increase of $2.2 million or 1.0%. Common shareholders' equity was $18.2 million
at March 31, 1998 compared with $17.4 million at December 31, 1997, an increase

RESULTS OF OPERATIONS

Interest Income

     Interest income for the quarter ended March 31, 1998 was $4.5 million, an
increase of $583,000 or 15.0% from the quarter ended March 31, 1997.  The
increase in interest income was due primarily to higher 

                                       12

interest income on loans and securities. Average loans were $161.4 million for
the quarter ended March 31, 1998 compared with $140.5 million for the quarter
ended March 31, 1997, an increase of $20.9 million or 14.9%. Internal growth
accounted for all of the $20.9 million increase in average loans. Average
securities were $55.0 million for the quarter ended March 31, 1998 compared with
$34.6 million for the quarter ended March 31, 1997, an increase of $20.4 million
or 59.0%.

Interest Expense

     Interest expense on deposits and other interest-bearing liabilities was
$2.2 million for the quarter ended March 31, 1998 compared with $1.9 million for
the quarter ended March 31, 1997, an increase of $317,000 or 16.6%. The increase
in interest expense was due primarily to an increase in average interest-bearing
liabilities, to $182.0 million for the quarter ended March 31, 1998 from $162.6
million for the quarter ended March 31, 1997, an increase of $19.4 million or
11.9%. In addition, the interest rate on average interest-bearing liabilities
increased to 4.97% from 4.78% for the same periods.

Net Interest Income

     Net interest income was $2.2 million for the quarter ended March 31, 1998
compared with $2.0 million for the quarter ended March 31, 1997, an increase of
$266,000 or 13.4%. The increase in net interest income resulted primarily from
growth in average earning assets to $225.3 million for the quarter ended March
31, 1998 from $193.4 million for the quarter ended March 31, 1997, an increase
of $31.9 million or 16.5%.

     The Company's net interest income is affected by changes in the amount and
mix of interest-earning assets and interest-bearing liabilities, referred to as
a "volume change." It is also affected by changes in yields earned on interest-
earning assets and rates paid on interest-bearing deposits and other borrowed
funds, referred to as a "rate change." The following tables set forth, for each
category of interest-earning assets and interest-bearing liabilities, the
average amounts outstanding, the interest earned or paid on such amounts, and
the average rate earned or paid for the quarters ended March 31, 1998 and 1997.
The tables also set forth the average rate earned on total interest-earning
assets, the average rate paid on total interest-bearing liabilities, and the net
interest margin on average total interest-earning assets for the same periods.

Provision and Allowance for Loan Losses

     In originating loans, the Company recognizes that credit losses will be
experienced and the risk of loss will vary with, among other things, general
economic conditions, the type of loan being made, the creditworthiness of the
borrower over the term of the loan and, in the case of a collateralized loan,
the quality of the collateral for such loan. The Company maintains an allowance
for loan losses based upon, among other things, historical experience, the
volume and type of lending conducted by the Company, the amount of nonperforming
assets, regulatory policies, generally accepted accounting principles, general
economic conditions, and other factors related to the collectibility of loans in
the Company's portfolio. In addition to unallocated allowances, specific
allowances are provided for individual loans when ultimate collection is
considered questionable by management after reviewing the current status of
loans which are contractually past due and considering the net realizable value
of the collateral for the loan.

     Management actively monitors the Company's asset quality and provides
specific loss allowances when necessary. Loans are charged-off against the
allowance for loan losses when appropriate. Although management believes it uses
the best information available to make determinations with respect to the
allowance for loan losses, future adjustments may be necessary if economic
conditions differ from the assumptions used in making the initial
determinations. As of March 31, 1998, the allowance for loan losses amounted to
$1.5 million or 0.92% of total loans. The allowance for loan losses as a
percentage of nonperforming loans was 162.7% at March 31, 1998.

     Provisions for loan losses are charged to income to bring the total
allowance for loan losses to a level deemed appropriate by management of the
Company based on such factors as historical experience, the volume and type of
lending conducted by the Company, the amount of nonperforming assets, regulatory
policies, generally accepted accounting principles, general economic conditions,
and other factors related to the collectibility of loans in the Company's
portfolio.

     The provision for loan losses for the quarter ended March 31, 1998 was
$370,000 compared with $20,000 for the quarter ended March 31, 1997. The
increase in provision came as a result of the growth in the loan portfolio from
$140.4 million at March 31, 1997 to $163.1 million at March 31, 1998.  The
provision was incurred to increase the allowance for loan loss to a more
appropriate level and to allow for continued loan growth. For the quarter ended
March 31, 1998, net charge-offs were $5,000.

Noninterest Income

     The Company's primary sources of recurring noninterest income are service
charges on deposit accounts and fee income. Excluding a $674,000 nonrecurring
gain from the sale of loans, noninterest income for the quarter ended March 31,
1998 increased to $488,000 from $386,000 for the quarter ended March 31, 1997,
an increase of $102,000 or 26.4%.  The gain on sale of loans was recorded when
the Company sold $2.0 million of loans originally purchased at a discount in
June of 1991 from the RTC.  The following table presents, for the periods
indicated, the major categories of noninterest income:

     After excluding the nonrecurring gain on the sale of loans, the increase in
noninterest income from March 31, 1997 to March 31, 1998, resulted primarily
from an increase in service charges on deposit accounts and fee income due to an
increase in the number of deposit accounts. Additionally, the Company's
increased emphasis on fee based services resulted in greater income from check
cashing, ATM fees, appraisal fees and wire transfer fees.

Noninterest Expenses

Noninterest expenses totaled $2.0 million for the quarter ended March 31, 1998
compared with $1.8 million for the quarter ended March 31, 1997, an increase of
$190,000 or 10.3%. The following table presents, for the periods indicated, the
major categories of noninterest expenses:

     Employee compensation and benefits expense for the quarter ended March 31,
1998 was $1.1 million, an increase of $150,000 or 16.1% over the same period in
1997. The increase was due primarily to normal salary increases and the staffing
of a new location in Texarkana, which opened in August of 1997 and additional
staff at the Mt. Pleasant location to handle customer growth. The number of
full-time equivalent employees was 127.5 at March 31, 1998 compared with 111.5
at March 31, 1997, an increase of 14.3%.

  Non-staff expenses were $944,000 for the quarter ended March 31, 1998 compared
with $904,000 for the same period in 1997, an increase of $40,0000 or 4.4%. Net
bank premises expense increased $12,000 or 4.4% to $286,000, due primarily to
the addition of the Texarkana banking facility.

   Legal and professional fees increased $24,000 or 30.8% due primarily to
independent loan review expenses and bankruptcy and litigation proceedings.  The
increase in advertising of $6,000 or 13.0% was due to additional advertising
campaigns initiated in early 1998 as compared to the same time period of 1997.
Other non-staff expenses include director fees, insurance, franchise tax,
telephone expense and other miscellaneous expenses, the combination of which
increased $9,000 or 2.3% to $406,000 as of March 31, 1998.

Income Taxes

     Income tax expense increased approximately $220,000 to $295,000 for the
quarter ended March 31, 1998 from $75,000 for the same period in 1997. The
increase was primarily attributable to the gain on sale of loans in the amount
of $674,000.  The Company did not have a gain from the sale of loans in the
first quarter of 1997.

FINANCIAL CONDITION

Loan Portfolio

     Total loans were $163.1 million at March 31, 1998, an increase of $5.7
million or 3.6% from $157.4 million at December 31, 1997. Loan growth occurred
primarily in commercial loans. Loans comprised 71.4% of total earning assets at
March 31, 1998 compared with 70.5% at December 31, 1997.

     The following table summarizes the loan portfolio of the Company by type of

     Nonperforming assets were $1.6 million at March 31, 1998 compared with $1.9
million at December 31, 1997, reflecting continued strong asset quality. The
ratio of nonperforming assets to total loans and other real estate was 1.0% and

SECURITIES

     Securities totaled $52.6 million at March 31, 1998, a decline of $5.5
million from $58.1 million at December 31, 1997. The decline occurred as
maturing securities were used to fund loans. At March 31, 1998, securities
represented 21.2% of total assets compared with 23.8% of total assets at
December 31, 1997. The yield on average securities for the quarter ended March
31, 1998 was 6.66% compared with 6.61% for the same period in 1997. At March 31,
1998, securities included $10.4 million in U.S. Treasury securities, $20.7
million in U.S. Government securities, $19.3 million in mortgage-backed
securities, $1.1 million in equity securities and $1.1 million in municipal
securities. The average life of the securities portfolio at March 31, 1998 was
approximately two years and six months.

PREMISES AND EQUIPMENT

     Premises and equipment totaled $6.4 million at March 31, 1998 and at March
31, 1997.  Although the net change shows only a slight increase in fixed assets,
some assets were capitalized during the period and normal depreciation was
recorded.

DEPOSITS

     At March 31, 1998, demand, money market and savings deposits accounted for
approximately 44.1% of total deposits, while certificates of deposit made up
55.9% of total deposits. Noninterest-bearing demand deposits totaled $39.1
million or 17.4% of total deposits at March 31, 1998 compared with $46.3 million
or 20.8% of total deposits at December 31, 1997. The average cost of deposits,
including noninterest-bearing demand deposits, was 3.98% for the quarter ended
March 31, 1998 compared with 3.84% for the same period in 1997. The increase in
the average cost of deposits was primarily due to the increased share of
interest-bearing deposits.

LIQUIDITY

     The Company's Asset/Liability Management Policy is intended to maintain
adequate liquidity for the Company. 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.  The Company's liquidity needs are
primarily met by growth in core deposits.  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 rely on these
external funding sources.  The cash and federal funds sold position,
supplemented by amortizing investments along with payments and maturities within
the loan portfolio, have historically created an adequate liquidity position.

     The Company's cash flows are composed of three classifications: cash flows
from operating activities, cash flows from investing activities, and cash flows
from financing activities. Net cash provided  by operating activities was $3.3
million and $1.3 million for the quarters ended March 31, 1998 and 1997,
respectively. The difference related mainly to the proceeds from the sale of
loans in the quarter ended March 31, 1998.

     Net cash (used) by investing activities was $(7.4) million and $(10.9)
million for the quarters ended March 31, 1998 and 1997, respectively. In the
quarter ended March 31, 1998, the Company funded more loans than it received in
maturing investments. The Company also experienced an increase in federal funds
in the quarter ended March 31, 1998 over the quarter ended March 31, 1997.

     Net cash provided by financing activities was $2.2 million and $8.3 million
for the quarters ended March 31, 1998 and 1997, respectively. The difference was
due primarily to a greater increase in deposits during the quarter ended March
31, 1997.

CAPITAL RESOURCES

     Total shareholders' equity as of March 31, 1998 was $19.0 million, an
increase of $727,000 or 4.0% compared with shareholders' equity of $18.3 million
at December 31, 1997. The increase was largely attributable to net earnings for
the quarter ended March 31,1998 of $720,000.

     Both the Board of Governors of the Federal Reserve System, with respect to
the Company, and the Federal Deposit Insurance Corporation, with respect to the
Bank, have established certain minimum risk-based capital standards that apply
to bank holding companies and federally insured banks, respectively. The 
Company's risk-based capital ratios remain above the levels designated as "well
capitalized" on March 31, 1998, with Tier 1 capital, total risk-based capital
and leverage capital ratios of 11.13%, 12.01% and 7.61%, respectively. The
Bank's risk-based capital ratios remain above the levels designated as "well
capitalized" on March 31, 1998, with Tier-1 capital, total risk-based capital
and leverage capital ratios of 10.90%, 11.82% and 7.25%, respectively.

YEAR 2000

     The Company established a Year 2000 Task Force in September 1997 to ensure
there will be no material adverse effect on customers or disruption to business
operations as a result of a failure of the 

                                       22
<PAGE>
 
Company or third parties to properly process any data on or after January 1,
2000. The project plan consists of five phases - Awareness, Assessment,
Renovation, Validation and Implementation. The Awareness and Assessment phases
are complete and the Renovation and Validation phases are currently in process
and on schedule. The inventory of systems has been performed and the risk
assessment and prioritizing of those systems is complete. The Company does not
utilize any in-house developed software. All software utilized has been provided
by established software companies who retain the responsibility for Year 2000
compliance. These respective vendors have been contacted and requested to
provide the current compliance status of their respective software and hardware
systems. Their responses are being actively monitored and testing schedules are
being developed and deployed based on the responses. It is anticipated that the
validation phase will be complete by late 1998 or the first quarter 1999.
Incremental costs for causing computer applications to be Year 2000 compliant 
are presently estimated to be immaterial. The Company is currently conducting
thorough internal testing of all third party hardware and software systems in an
attempt to ensure Year 2000 compliance. The Company is also developing detailed
contingency plans in the event of any system failure associated with Year 2000.

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     The Company's primary market risk exposure is to changes in market interest
rates.  The Company's exposure to such risk is reviewed on a regular basis by
the Asset Liability Committee. Interest rate risk is the potential of economic
losses due to future interest rate changes. These economic losses can be
reflected as a loss of future net interest income and/or a loss of current fair
market values. The objective is to measure the effect on net interest income and
to adjust the balance sheet to minimize the inherent risk while at the same time
maximizing income. Management realizes certain risks are inherent, and that the
goal is to identify and accept the risks.

    The Company applies a market value ("MV") methodology to gauge its interest
rate risk exposure as derived from its simulation model.  Generally, MV is the
discounted present value of the difference between incoming cash flows on
interest-earning assets and other investments and outgoing cash flows on
interest-bearing liabilities.  The application of the methodology attempts to
quantify interest rate risk by measuring the change in the MV that would result
from a theoretical 200 basis point change in market interest rates.  Both a 200
basis point increase and a 200 basis point decrease in market rates are
considered.

     At March 31, 1998, it was estimated that the Company's MV would decrease
19.3% in the event of a 200 basis point increase in market interest rates.  The
Company's MV at the same date would increase 11.2% in the event of a 200 basis
point decrease in market interest rates.
