        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                              (Unaudited)


1.  INTERIM FINANCIAL STATEMENTS

The accompanying unaudited condensed consolidated financial statements, 
which are for interim periods, do not include all disclosures provided in 
the annual consolidated financial statements.  These financial statements 
and the footnotes thereto should be read in conjunction with the annual 
consolidated financial statements for the year ended December 31, 2004 for 
Commercial Bankshares, Inc. (the "Company").

All material intercompany balances and transactions have been eliminated.

In the opinion of management, the accompanying unaudited condensed 
consolidated financial statements contain all adjustments necessary for 
a fair presentation of the financial statements.  Those adjustments are 
of a normal recurring nature.  The results of operations for the three 
month period ended March 31, 2005, are not necessarily indicative of the 
results to be expected for the full year.

In preparing the consolidated financial statements, management is required 
to make estimates and assumptions that affect the reported amounts of assets 
and liabilities at the dates of the statements of financial condition and 
revenues and expenses for the periods covered.  Actual results could differ 
from those estimates and assumptions.


2.  STOCK OPTIONS

The following table provides the Statement of Financial Accounting Standard 
(SFAS) No. 148 disclosure of pro forma net income and earnings per share as 
if the Company had adopted the fair value method of accounting for stock-
based awards for the three month period ended March 31, 2005 compared to the 
same period in the prior year:

3.  PER SHARE DATA

Earnings per share have been computed by dividing net income by the weighted 
average number of shares of common stock (basic earnings per share) and by 
the weighted average number of shares of common stock plus dilutive shares 
of common stock equivalents outstanding (diluted earnings per share).  
Common stock equivalents include the effect of all outstanding stock options, 
using the treasury stock method.  

The following tables reconcile the weighted average shares used to calculate 
basic and diluted earnings per share (EPS)(in thousands, except per share 
amounts):

            ======      =====      ====      ======       =====      ====


All outstanding options were included in the computation of diluted earnings 
per share because the average market price of the common shares was greater 
than the options' exercise price.


4. COMMITMENTS AND CONTINGENCIES

Standby letters of credit are conditional commitments issued by Commercial 
Bank of Florida ("the Bank") to guarantee the performance of a customer to 
a third party.  The Bank had outstanding standby letters of credit in the 
amount of $4.7 million as of March 31, 2005 as compared to $5.9 million as 
of December 31, 2004.  Approximately $398,000 of the standby letters of 
credit outstanding at March 31, 2005 were issued subsequent to December 31, 
2004 and are being carried at fair value.  The Bank's exposure to credit 
loss in the event of non-performance by the other party to the financial 
instrument for standby letters of credit is represented by the contractual 
amounts of those instruments.  The Bank uses the same credit policies in 
establishing conditional obligations as those for on-balance sheet 
instruments.  The credit risk involved in issuing letters of credit is 
essentially the same as that involved in extending loan facilities to 
customers.  Collateral held varies but may include cash, or the goods 
acquired by the customer for which the standby letter of credit was issued.  


                                    6



 
Since certain letters of credit are expected to expire without being drawn 
upon, they do not necessarily represent future cash requirements. 


5.  NEW ACCOUNTING PRONOUNCEMENTS
   
In December 2004, the Financial Accounting Standards Board ("FASB") issued 
Statement of Financial Accounting Standards ("SFAS") No. 153, "Exchanges of 
Nonmonetary Assets, an Amendment of APB Opinion No. 20".  Under APB No. 20 
there was an exception from fair value measurement for nonmonetary exchanges 
of similar productive assets.  SFAS No. 153 replaces this exception with a 
general exception from fair value measurement for exchanges of nonmonetary 
assets that do not have commercial substance.  A nonmonetary exchange has 
commercial substance if the future cash flows of the entity are expected to 
change significantly as a result of the exchange.  SFAS No. 153 is effective 
for nonmonetary asset exchanges occurring in fiscal periods beginning after 
June 15, 2005, and shall be applied prospectively.  Earlier application is 
permitted for nonmonetary asset exchanges occurring in fiscal periods after 
December 2004.  The provisions of this statement are not expected to have a 
material effect on the financial statements of the Company.  

In December 2004, the FASB issued SFAS No. 123 (revised 2004), entitled 
"Share-Based Payment" that will require compensation costs related to share-
based payment transactions to be recognized in the Company's financial 
statements.  With limited exceptions, the amount of compensation cost will 
be measured based on the grant-date fair value of the equity or liability 
instruments issued.  Compensation cost will be recognized over the period 
that an employee provides service in exchange for the award.  SFAS No. 123(R) 
is a revision of SFAS No. 123, "Accounting for Stock Issued to Employees," 
and its related implementation guidance.  The Company currently applies APB 
No. 25 and related interpretations in the accounting for stock options under 
the intrinsic value method of APB No. 25 and provides pro forma disclosure 
of the Company's stock-based compensation expense as currently required by 
SFAS No. 123.  See Note 2 of Notes to Consolidated Financial Statement for 
this pro forma disclosure.  Management of the Company intends to adopt SFAS 
No. 123(R) as required on January 1, 2006, using the modified prospective 
application method.  The provisions of this statement are not expected to 
have a material effect on the financial statements of the Company.  

In March 2004, the FASB Emerging Issues Task Force (EITF) reached a consensus 
on EITF issue No. 03-1 (EITF 03-1), "The Meaning of Other-Than-Temporary 
Impairment and Its Application to Certain Investments."  The consensus 
provided guidance for the meaning of other-than-temporary impairment and 
its application to investments classified as either available-for-sale or 
held-to-maturity under SFAS 115, "Accounting for Certain Investment in Debt 
and Equity Securities" and to equity securities accounted for under the cost 
method.  The guidance was effective for other-than-temporary impairment 
evaluations made in reporting periods beginning after June 15, 2004.  In 
September 2004, the Financial Accounting Standards Board (FASB) issued a 
final FASB Staff Position, FSP EITF Issue 03-1-1, which delayed the effective 
date for the measurement and recognition guidance of EITF 03-1.  We are not 
able to evaluate the impact of adopting EITF 03-1 until final guidance has 
been issued.

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


The following discussion and analysis of the Company's consolidated results 
of operations and financial condition should be read in conjunction with the 
unaudited interim consolidated financial statements and the related notes 
included herein and the consolidated financial statements for the year ended 
December 31, 2004 appearing in the Company's Annual Report on Form 10-K filed 
with the Securities and Exchange Commission.

CORPORATE OVERVIEW

Commercial Bankshares, Inc. (the "Company"), a Florida corporation organized 
in 1988, is a bank holding company whose wholly-owned subsidiary and principal 
asset is the Commercial Bank of Florida (the "Bank").  The Company, through 
its ownership of the Bank, is engaged in a commercial banking business.  Its 
primary source of earnings is derived from income generated by its ownership 
and operation of the Bank.  The Bank is a Florida chartered banking 
corporation with fourteen branch locations throughout Miami-Dade and Broward 
counties in South Florida.  The Bank primarily focuses on providing 
personalized banking services to businesses and individuals within the 
market areas where its banking offices are located.


RESULTS OF OPERATIONS

Three Months Ended March 31, 2005 and 2004

The Company's net income for the three months ended March 31, 2005, was $2.91 
million, an 8% increase over net income for the same three month period ended 
March 31, 2004 of $2.70 million.  Basic and diluted earnings per share were 
$.49 and $.46, respectively, for the three months ended March 31, 2005, as 
compared to $.46 and $.44, respectively, for the three months ended March 31, 
2004.  

The Company's first quarter tax-equivalent net interest income increased 9% 
to $8.37 million, from $7.71 million in the first quarter in 2004. The 
increase is the result of growth in average earning assets, which have 
increased 12% to $849 million for the first quarter of 2005, as compared to 
$758 million for the first quarter of 2004.  The tax-equivalent net interest 
yield for the three months ended March 31, 2005 was 4.00%, as compared to 
4.09% for the same period in 2004.  The decrease in net interest yield is 
the result of increased cost of funds.  The net interest margin has been 
calculated on a tax-equivalent basis, which includes an adjustment for 
interest on tax-exempt securities.

Non-interest income decreased by $39,000, or 5%, for the first quarter of 
2005, as compared to the corresponding period in 2004.  The decrease is due 
to a reduction in service charges on deposit accounts of $64,000, partially 
offset by an increase in other fees and service charges of $25,000, which is 
primarily related to real estate tax refunds and insurance refunds.  
 
Non-interest expense for the first quarter of 2005 increased $155,000, or 4% 
from the same quarter in 2004, due primarily to increases in salaries and 
employee benefits, furniture and equipment expense and telephone and fax 
expense, partially offset by decreases in insurance expense.  Salaries and 
employee benefits increased $115,000, or 4%, due to the addition of two staff 
positions and normal salary adjustments.  Furniture and equipment expense 
increased $33,000, or 17%, due to an increase in the maintenance of the 
Company's fourteen branch locations.  Telephone and fax expense increased 
$40,000 due to credits which reduced the first quarter, 2004 telephone 
expense.  Insurance expense decreased by $19,000, or 19%, after the renewal 
of certain policies which resulted in premium reductions.    


                                    8



Company management continually reviews and evaluates the allowance for loan 
losses.  In evaluating the adequacy of the allowance for loan losses, 
management considers the results of its methodology, along with other factors 
such as the amount of non-performing loans and the economic conditions 
affecting the Company's markets and customers.  The allowance for loan losses 
was $4.77 million at March 31, 2005, as compared with $4.75 million at 
December 31, 2004.  For the three months ended March 31, 2005, the allowance 
for loan losses was increased with a provision for loan losses of $20,000 
and increased by approximately $2,000 in net recoveries.  For the three 
months ended March 31, 2004, the allowance was decreased with a credit for 
loan losses of $42,000 and increased by approximately $130,000 in net 
recoveries.  The allowance as a percentage of total loans has decreased to 
1.03% at March 31, 2005, from 1.04% at December 31, 2004.  Based on the 
nature of the loan portfolio and prevailing economic factors, management 
believes that the current level of the allowance for loan losses is 
sufficient to absorb probable losses in the loan portfolio.

Approximately $297 million, or 64%, of total loans was secured by non-
residential real estate, and $109 million, or 24%, of total loans was 
secured by residential real estate as of March 31, 2005.  Virtually all 
loans are within the Company's markets in Miami-Dade and Broward counties.

The Company had two non-accrual loans at March 31, 2005, totaling $331,000.  
If these loans were not on non-accrual an additional $5,000 in interest 
would have been earned for the first quarter of 2005.  There were no non-
accrual loans at March 31, 2004.


LIQUIDITY AND CAPITAL RESOURCES

The objective of liquidity management is to maintain cash flow requirements 
to meet immediate and ongoing future needs for loan demand, deposit 
withdrawals, maturing liabilities, and expenses.  In evaluating actual and 
anticipated needs, management seeks to obtain funds at the most economical 
cost.  Management believes that the level of liquidity is sufficient to meet 
future funding requirements.

For banks, liquidity represents the ability to meet both loan commitments and 
withdrawals of deposited funds.  Funds to meet these needs can be obtained 
by converting liquid assets to cash or by attracting new deposits or other 
sources of funding.  Many factors affect a bank's ability to meet liquidity 
needs.  The Bank's principal sources of funds are deposits, repurchase 
agreements, payments on loans, maturities and sales of investments.  As an 
additional source of funds, the Bank has credit availability with the 
Federal Home Loan Bank amounting to $139 million, and Federal Funds 
purchased lines available at correspondent banks amounting to $23 million 
as of March 31, 2005.

The Bank's primary use of funds is to originate loans and purchase investment 
securities.  The Bank purchased $20 million of investment securities during 
the first three months of 2005, and loans increased by $6 million.  Funding 
for the above came from increases in deposits of $43 million, an increase in 
securities sold under agreements to repurchase of $2 million and increases 
from proceeds of maturities and prepayments of investment securities of 
$5 million.

In accordance with risk-based capital guidelines issued by the Federal 
Reserve Board, the Company and the Bank are each required to maintain a 
minimum ratio of total capital to risk weighted assets of 8%.  Additionally, 
all bank holding companies and member banks must maintain "core" or "Tier 1" 
capital of at least 3% of total assets ("leverage ratio").  Member banks 
operating at or near the 3% capital level are expected to have well 
diversified risks, including no undue interest rate risk exposure, excellent 
control systems, good earnings, high asset quality, high liquidity, and well 
managed on- and off-balance sheet activities, and in general be considered 
strong banking organizations with a composite 1 rating under the CAMELS 


                                    9



rating system of banks.  For all but the most highly rated banks meeting the 
above conditions, the minimum leverage ratio is to be 3% plus an additional 
100 to 200 basis points.  The Tier 1 Capital, Tier 2 Capital, and Leverage 
Ratios of the Company were 12.90%, 14.17%, and 7.73%, respectively, as of 
March 31, 2005.


CRITICAL ACCOUNTING POLICIES

The Company's critical accounting policies are disclosed on page 16 of its 
2004 Annual Report under the heading Management's Discussion and Analysis of 
Financial Condition and Results of Operations, which report is filed with 
the Annual Report on Form 10-K for the year ended December 31, 2004.  On an 
ongoing basis, the Company evaluates its estimates and assumptions, 
including those related to valuation of the loan portfolio.  Since the date 
of the 2004 Annual Report, there have been no material changes to the 
Company's critical accounting policies.  


FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q may contain forward-looking statements 
(within the meaning of Section 21E of the Securities Exchange Act of 1934, 
as amended), representing the Company's expectations and beliefs concerning 
future events.  The actual results of the Company could differ materially 
from those indicated by the forward-looking statement because of various 
risks and uncertainties, including, without limitation, the Company's 
effective and timely initiation and development of new client relationships, 
the maintenance of existing client relationships and programs, the 
recruitment and retention of qualified personnel, possible or proposed 
products, branch offices, or strategic plans, the ability to increase sales 
of Company products and to increase deposits, the adequacy of cash flows 
from operations and available financing to fund capital needs and future 
growth, changes in management's estimate of the adequacy of the allowance 
for loan losses, changes in the overall mix of the Company's loan and 
deposit products, the impact of repricing and competitors' pricing 
initiatives on loan and deposit products as well as other changes in 
competition, the extent of defaults, the extent of losses given such 
defaults, the amount of lost interest income that may result in the event 
of a severe recession, the status of the national economy and the South 
Florida economy in particular, the impact that changing interest rates have 
on the Company's net interest margin, changes in governmental rules and 
regulations applicable to the Company and other risks in the Company's 
filings with the Securities and Exchange commission.  The Company cautions 
that its discussion of these matters is further qualified, as these risks 
and uncertainties are beyond the ability of the Company to control.  In 
many cases, the Company cannot predict the risks and uncertainties that 
could cause actual results to differ materially from those indicated in the 
forward-looking statements.

The Company undertakes no obligation to revise or update these forward-
looking statements to reflect events or circumstances after the date of this 
filing.

    ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

ASSET/LIABILITY MANAGEMENT AND INTEREST RATE RISK

Changes in interest rates can substantially impact the Company's long-term 
profitability and current income.  An important part of management's efforts 
to maintain long-term profitability is the management of interest rate risk.  
The goal is to maximize net interest income within acceptable levels of 
interest rate risk and liquidity.  Interest rate exposure is managed by 
monitoring the relationship between interest-earning assets and interest-
bearing liabilities, focusing on the size, maturity or repricing date, rate 
of return and degree of risk.  The Asset/Liability Management Committee of 
the Bank oversees the interest rate risk management and reviews the Bank's 
asset/liability structure on a quarterly basis.

The Bank uses interest rate sensitivity or GAP analysis to monitor the amount 
and timing of balances exposed to changes in interest rates.  The GAP 
analysis is not relied upon solely to determine future reactions to interest 
rate changes because it is presented at one point in time and could change 
significantly from day-to-day.  Other methods such as simulation analysis 
are utilized in evaluating the Bank's interest rate risk position.  The 
table presented below shows the Bank's GAP analysis at March 31, 2005.

(1) Investment securities include equity investment in the Federal Reserve 
Board and Federal Home Loan Bank.

Management's assumptions reflect the Bank's estimate of the anticipated 
repricing sensitivity of non-maturity deposit products.  Money market 
accounts have been allocated 25% to the "91-181 days" category, 25% to the 
"182-365 days" category, and 50% to the "over 1 year" category.  Interest 
checking and savings are allocated to the "over 1 year" category.  If non-
maturing deposits had been shown at their contractual term (90 days or less 
column), the cumulative gap as a percentage of total earning assets would 
have been -20.6%, -21.5%, -20.3% and 21.6% for 90 days or less, 91-181 days, 
182-365 days and over 1 year, respectively. 

The Bank uses simulation analysis to quantify the effects of various 
immediate parallel shifts in interest rates on net interest income over the 
next 12 month period.  Such a "rate shock" analysis requires key assumptions 
which are inherently uncertain, such as deposit sensitivity, cash flows from 
investments and loans, reinvestment options, management's capital plans, 
market conditions, and the timing, magnitude and frequency of interest rate 
changes.  As a result, the simulation is only a best-estimate and cannot 
accurately predict the impact of the future interest rate changes on net 
income.  As of March 31, 2005, the Bank's simulation analysis projects a 
decrease to net interest income of 7.5%, assuming an immediate parallel 
shift downward in interest rates by 200 basis points.  If rates rise by 200 
basis points, the simulation analysis projects net interest income would 
increase by 4.4%.  These projected levels are within the Bank's policy limits.

       
       
       
                       ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures 

As of the end of March 31, 2005, the Company's management carried out an 
evaluation, under the supervision and with the participation of the Company's 
management, including its Chief Executive Officer and Chief Financial 
Officer, of the effectiveness of the design and operation of its disclosure 
controls and procedures (as defied in Rule 13a-15(e) under the Securities 
Exchange Act of 1934).  Based upon that evaluation, the Chief Executive 
Officer and Chief Financial Officer concluded that the design and operation 
of these disclosure controls and procedures were effective as of the end of 
the period covered by this report.

The work undertaken by the Company to comply with Section 404 of the 
Sarbanes-Oxley Act of 2002 involved the identification, documentation, 
assessment and testing of the Company's internal control over financial 
reporting in order to evaluate the effectiveness of such controls.

(b) Changes in Internal Control Over Financial Reporting

There have been no significant changes in the Company's internal control 
over financial reporting during the quarter ended March 31, 2005 that has 
materially affected, or is reasonably likely to materially affect, the 
Company's internal control over financial reporting.
