                FIRST FINANCIAL BANKSHARES, INC. AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1 - Basis of Presentation

    In the opinion of management,  the consolidated financial statements reflect
    all adjustments necessary for a fair presentation of the Company's financial
    position  and  results  of operations.  All  adjustments  were  of a  normal
    recurring  nature.  However,  the results of operations for the three months
    ended March 31,  2000 are not  necessarily  indicative  of the results to be
    expected for the year ended December 31, 2000.

Note 2 - Earnings Per Share

    Basic earnings per common share is computed by dividing net income available
    to common shareholders by the weighted average number of shares  outstanding
    during the period.  In computing  diluted earnings per common share for the
    quarters ended  March  31,  2000 and 1999,  the  Company  assumes  that all
    outstanding  options to purchase  common  stock have been  exercised at the
    beginning of the year (or time of issuance,  if later). The dilutive effect
    of the  outstanding  options is  reflected by  application  of the treasury
    stock method,  whereby the proceeds from the exercised  options are assumed
    to be used to purchase  common stock at the average market price during the
    respective  period.  The weighted average common shares outstanding used in
    computing  basic earnings per common share for the quarters ended March 31,
    2000 and 1999,  were  9,974,306 and  9,953,794  shares,  respectively.  The
    weighted  average  common  shares  outstanding  used in  computing  diluted
    earnings per common  share for the quarters  ended March 31, 2000 and 1999,
    were 10,006,257 and 9,996,399 shares, respectively.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

Operating Results
- -----------------

Net income for the first quarter 2000 totaled $6.7 million,  an increase of $600
thousand,  or 10.1% over earnings of $6.1 million for the same period last year.
Higher net  interest  income and  noninterest  income were the  primary  factors
contributing to the improved earnings.  On a per share basis,  earnings amounted
to $ .68 per share as compared to $ .62 per share for first quarter 1999. Return
on  average  assets and return on  average  equity  for the first  quarter  2000
amounted to 1.60% and 15.18%, respectively.  For the same period in 1999, return
on average  assets and return on average  equity  amounted  to 1.49% and 14.78%,
respectively.

Tax-equivalent  net interest income for the first quarter 2000 amounted to $17.6
million as compared to $16.8 million for the same period last year. The increase
for 2000 was  attributable  to a $27 million  increase in average earning assets
and an improved net interest  yield which amounted to 4.64% as compared to 4.53%
for the first quarter last year.

The  provision  for loan losses for the first quarter 2000 totaled $741 thousand
as compared to $470  thousand for the first  quarter last year.  Net charge offs
for the first quarter  totaled $392  thousand  which,  on an  annualized  basis,
amounted to .20% of average loans as compared to .27% for the full year of 1999.
At March  31,  2000,  the  allowance  for loan  losses  amounted  to  485.6%  of
nonperforming loans and 1.15% of total loans, which was considered by Management
to be adequate.

Total noninterest income for the first quarter was $6.5 million,  an increase of
$406 thousand,  or 6.7%, over the same period last year. Service fees on deposit
accounts were up $265  thousand,  or 8.5%,  and were the primary  factor for the
overall  improvement in noninterest income. The increase in deposit service fees
resulted primarily from increased transaction volume.

Noninterest  expense for the first  quarter 2000 amounted to $12.9 million which
was $29 thousand below the same period last year. Salaries and employee benefits
expense were up $78 thousand,  or 1.2%.  Net occupancy  expense  decreased  $114
thousand  and  resulted  primarily  from  lower  depreciation  and  repairs  and
maintenance  expense.  The  Company's  key  indicator of  operating  efficiency,
noninterest  expense as a percent  of net  interest  income on a  tax-equivalent
basis and  noninterest  income,  was 53.61% for the first quarter as compared to
56.69% for the first quarter in 1999.

Balance Sheet Review
- --------------------

Total assets at March 31, 2000, amounted to $1.708 billion as compared to $1.723
billion at December 31, 1999,  and $1.677  billion at March 31, 1999.  The March
31,  2000,  decline in total assets from the  year-end  1999 balance  reflects a
seasonal decrease in total deposits. The balance sheets presented reflect normal
recurring adjustments and accruals.

Loans at March 31,  2000,  net of unearned  discount,  totaled  $808  million as
compared to $797 million at year-end 1999 and $773 million at March 31, 1999. As
compared to year-end  1999  amounts,  loans at March 31, 2000,  reflect (i) a $7
million  decrease in commercial,  financial and agricultural  loans;  (ii) a $13
million  increase in real estate loans; and (iii) a $5 million increase in loans
to individuals. Investment securities at March 31, 2000, totaled $671 million as
compared to $656  million at year-end  1999 and $634  million at March 31, 1999.
The net unrealized gain in the investment  portfolio at March 31, 2000, amounted
to $13.8  million.  With an overall  yield of 6.26%,  the  investment  portfolio
continues to provide a positive contribution to the Company's earnings. At March
31, 2000, the Company did not hold any CMOs that entail higher risks

                                      -10-





than standard mortgage-backed  securities.  Total investment securities at March
31, 2000,  included  structured notes with an amortized cost of $2.0 million and
an approximate  market value of $1.9 million.  Total deposits at March 31, 2000,
amounted to $1.500  billion as compared to $1.525  billion at year-end  1999 and
$1.490  billion at March 31, 1999.  The  decrease  from  December  31, 1999,  is
considered seasonal and not indicative of a downward trend in total deposits.

Nonperforming assets at March 31, 2000, totaled $1.9 million as compared to $2.1
million at December  31,  1999.  The  decrease  resulted  primarily  from a $288
thousand decrease in nonaccrual loans. At .24% of loans plus foreclosed  assets,
Management  considers  nonperforming  assets to be at a manageable  level and is
unaware  of  any  material   classified   credit  not   properly   disclosed  as
nonperforming.

Liquidity and Capital
- ---------------------

The Company's  consolidated  statements of cash flows are presented on page 8 of
this report. At March 31, 2000, the parent company had no debt outstanding under
its $25 million line of credit with an unaffiliated financial institution. Total
equity capital  amounted to $182.4 million at March 31, 2000,  which was up from
$178.7  million at  year-end  1999 and $172.2  million  at March 31,  1999.  The
Company's  risk-based capital and leverage ratios at March 31, 2000, were 18.60%
and 9.93%, respectively. The first quarter 2000 cash dividend of $0.30 per share
totaled $3.0 million and represented 44.4% of first quarter  earnings.  On April
25, 2000, the Company  declared a $0.33 per share cash dividend  payable July 1,
2000.

Interest Rate Risk
- ------------------

Interest  rate  risk  results  when  the  maturity  or  repricing  intervals  of
interest-earning  assets and  interest-bearing  liabilities  are different.  The
Company's  exposure  to  interest  rate risk is managed  primarily  through  the
Company's strategy of selecting the types and terms of  interest-earning  assets
and  interest-bearing  liabilities  which  generate  favorable  earnings,  while
limiting the potential negative effects of changes in market interest rates. The
Company uses no off-balance-sheet  financial instruments to manage interest rate
risk.  Each  subsidiary  bank has an  asset/liability  committee  which monitors
interest rate risk and compliance with investment policies. Interest-sensitivity
gap and simulation  analyses are among the ways that the subsidiary  banks track
interest rate risk.  Since year-end 1999,  there has been no material  change in
the Company's interest rate risk.

                                      -11-





Item 3.           Quantitative and Qualitative Disclosures About Market Risk

Management  considers  interest  rate risk to be a  significant  market risk for
the Company. See "Item 2 -  Management's  Discussion  and  Analysis of Financial
Condition and Results of Operations" for disclosure  regarding this market risk.
The Company has  procedures to monitor  market risk and has  determined  that no
material changes in market risk have occurred since December 31, 1999.

                                      -12-
