                   COMPUDYNE CORPORATION AND SUBSIDIARIES
                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                (UNAUDITED)

1. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of
CompuDyne Corporation and its subsidiaries (the "Company"), have been
prepared pursuant to the rules and regulations of the Securities and
Exchange Commission.  The consolidated balance sheet as of December 31,
2000 has been derived from the Company's December 31, 2000 audited
financial statements.  Certain information and note disclosures normally
included in the annual financial statements, prepared in accordance with
accounting principles generally accepted in the United States of America,
have been condensed or omitted pursuant to those rules and regulations,
although the Company believes that the disclosures made are adequate to
make the information presented not misleading.

In the opinion of management, the accompanying unaudited consolidated
financial statements reflect all necessary adjustments and
reclassifications (all of which are of a normal, recurring nature) that
are necessary for fair presentation for the periods presented.  It is
suggested that these consolidated financial statements be read in
conjunction with the consolidated financial statements and the notes
thereto included in the Company's annual report filed with the
Securities and Exchange Commission on Form 10-K for the year ended
December 31, 2000 and its subsequent reports on Form 10-Q.

New Accounting Pronouncements:

During October 2001, the Financial Accounting Standards Board ("FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 144,
"Accounting for the Impairment or Disposal of Long-Lived Assets."  SFAS
No. 144 supersedes SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of," and
replaces accounting and reporting provisions of APB Opinion No. 30,
"Reporting Results of Operations Reporting the Effects of Disposal of a
Segment of a Business and Extraordinary , Unusual and Infrequently
Occurring Events and Transactions," as it relates to the disposal of a
segment of a business. SFAS No. 144 requires the use of a single
accounting model for long-lived assets to be disposed of by sale,
including discontinued operations, by requiring those long-lived assets
to be measured at the lower of carrying amount or fair value less costs
to dispose.  The impairment recognition and measurement provisions of
SFAS No. 121 were retained for all long-lived assets to be held and used
with the exception of goodwill. The Company will adopt this standard on
January 1, 2002.  Management has not yet determined the impact that the
adoption of this statement will have on the Company's financial
statements.

In June 2001, the FASB issued two new pronouncements: SFAS No. 141,
Business Combinations, and SFAS No. 142, Goodwill and Other Intangible
Assets. SFAS 141 is effective as follows: a) use of the
pooling-of-interest method is prohibited for business combinations
initiated after June 30, 2001; and b) the provisions of SFAS 141 also
apply to all business combinations accounted for by the purchase method
that are completed after June 30, 2001 (that is, the date of the
acquisition is July 1, 2001 or later). There are also transition
provisions that apply to business combinations completed before July 1,
2001, that were accounted for by the purchase method.  SFAS 142 is
effective for fiscal years beginning after December 15, 2001 to all
goodwill and other intangible assets recognized in an entity's balance
sheet at that date, regardless of when those assets were initially
recognized. The Company is currently evaluating the provisions of SFAS
141 and SFAS 142 and has not yet determined the impact that adoption of
such statements will have on its consolidated financial statements.

In September 2000, SFAS No. 140, "Accounting for Transfers and Servicing
of Financial Assets and Extinguishments of Liability", replaced SFAS
Statement No. 125.  The Statement provides accounting and reporting
standards for transfers and servicing of financial assets and
extinguishments of liabilities. The Company adopted SFAS 140 effective
April 1, 2001.  The adoption of SFAS 140 did not have any impact on the
financial position, results of operations, or cash flows of the Company.

Certain 2000 amounts have been reclassified to conform to the 2001
presentation.

5. EARNINGS PER SHARE

Basic earnings per share is computed by dividing income available to
common shareholders by the weighted-average number of shares outstanding
for the period.  Diluted earnings per share is computed in a manner
consistent with that of basic earnings per share and reflects the
potential dilution that could occur if securities or other contracts to
issue common stock were exercised or converted into common stock.

The following is a reconciliation of the amounts used in calculating
basic and diluted earnings per common share:

6. PROPOSED MERGER WITH TIBURON

Tiburon Investment/Acquisition
------------------------------
On June 19, 2001, the Company purchased 624,996 shares of common stock
of Tiburon, Inc. ("Tiburon"), from certain of Tiburon's shareholders for
$3.0 million in cash which represents a 12.5% ownership interest. The
Company also purchased 520,833 newly issued shares of 7.5% cumulative
convertible preferred stock of Tiburon for an additional $3.0 million in
cash. These purchases were made pursuant to agreements (the "Agreements")
entered into on May 10, 2001. These share purchases were funded by bank
borrowings. Prior to the date of the purchase of the common and
preferred stock, the Company had a Cooperative Agreement with Tiburon
enabling the companies to sell certain products and services jointly to
certain customers. Pursuant to the Agreements, the Company has an option
to cause the merger of Tiburon into a wholly owned subsidiary of the
Company ("Stage 2").  The Company exercised this option on July 9, 2001.
Consummation of the Stage 2 merger is subject to the approval of the
Company's shareholders, and certain other considerations. In the Stage 2
merger, the holders of Tiburon common stock will receive Company common
stock in exchange for their shares of Tiburon common stock in a ratio
determined by dividing the merger price by the value assigned to the
Company's common stock. The merger price (to be paid in shares of
Company common stock) for the Tiburon common stock is $4.80 per share
plus increments of $0.045 per share for each full month after September
2, 2001, until March 2, 2002, $0.05 per share for each of the next six
full months and $0.075 per share for each full month thereafter until
the Stage 2 merger is completed.  For purposes of the Stage 2 merger
exchange ratio, the Company's common stock has, pursuant to the
Agreements, been valued, based on its volume weighted average price
reported on the NASDAQ National Market for the sixty days ended July 6,
2001, at $8.6164 per share.

In connection with the acquisition of the Tiburon common and preferred
shares of stock, the Company entered into an arrangement (the
"Arrangement") with William Blair Mezzanine Capital Fund II, L.P. (the
"Shareholder").  The Shareholder owned 1.076 million shares of the
Company's common stock and warrants to purchase 297,924 shares of the
Company's common stock and held a $9 million subordinated note issued by
the Company bearing annual interest at 13.15%.  The Arrangement allowed
the Shareholder to put its stock and the shares underlying its warrants
to the Company if the Company completed Stage 2 of the Tiburon
Agreement.  The put price was to be determined by agreement between the
Company and the Shareholder. The Arrangement became effective when the
Company exercised its option to complete Stage 2.  On October 29, 2001
the Company repaid all of the Shareholder's outstanding subordinated
debt and arranged for the sale of the Shareholder's outstanding stock
and shares underlying its warrants (See note 9).






7. INVESTMENT IN TIBURON COMMON STOCK

The Company's investment in Tiburon common stock is accounted for using
the equity method since the Company has the ability to exercise
significant influence over the operations of Tiburon. The Company has
included its share of the results of operations of Tiburon from June 19,
2001, the date of acquisition, in the accompanying consolidated statement
of income.  The amount of equity underlying the Tiburon common stock at
the date of acquisition totaled approximately $800 thousand.  The
difference of approximately $2.2 million is included in the investment
balance and is being amortized over 15 years.


8. LONG-TERM DEBT

Long-term debt consists of the following:

</TABLE>

In June 2001, the Company obtained an  $11.5 million bank borrowing,
bearing interest at LIBOR plus a variable margin, collateralized by
virtually all of the Company's assets, due in quarterly installments
beginning on September 30, 2001.  The Company used $6 million of the
$11.5 million to acquire $3 million in Tiburon common stock and $3
million in Tiburon convertible preferred stock.  The remaining $5.5
million was used to repay the existing note payable.

9. SUBSEQUENT EVENT - SALE OF COMMON STOCK

On October 29, 2001 the Company completed the sale of 1.076 million new
common shares in a Private Investment to Public Equity transaction.  The
stock was sold at a price of $12.00 per share which netted the Company
approximately $12.0 million in new equity capital after fees and
expenses.

In this same transaction, the Company also arranged for the sale of
approximately 1.37 million CompuDyne common shares and shares underlying
warrants owned by William Blair Mezzanine Capital Partners II, L.P.
(the "Shareholder").  As a result of this transaction the Shareholder
realized approximately $12.8 million, and by agreement with the
Shareholder, the Company realized approximately $2.5 million in net
capital proceeds.  In addition, the Company realized approximately $1.0
million from the exercise of the Shareholder warrants.  The Company
utilized the proceeds of this offering to retire the $9 million, 13.15%
subordinated note held by the Shareholder and to pay down other bank
debt.  Since the $9 million subordinated debt was repaid prior to its
maturity, the Company incurred a $270 thousand (3%) prepayment fee.

      MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                       AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

Amounts shown for 2000 for the Corrections segment have been reclassified
for comparative purposes.

Third Quarter 2001 and 2000 Comparison
--------------------------------------

Net sales for the Company were $31.4 million for the third quarter of
2001, an increase of $1.0 million from $30.4 million for the third
quarter of 2000. Sales in the Corrections segment were $19.7 million,
an increase of  $817 thousand from $18.9 million in 2000.  Net sales for
the Attack Protection segment were $5.6 million in the third quarter of
2001, a decrease of $547 thousand from $6.1 million for the same period
in 2000.  This change is attributable to the addition of sales for the
current fiscal year at Fiber SenSys (acquired November 2000), and
increased sales at Sysco which were offset by decreased sales at
Norshield.  Net sales for the Federal Systems segment increased $1.5
million to $5.0 million in the third quarter of 2001, from $3.5 million
in the same period in 2000. This increase is due to some large task
orders awarded to Quanta Systems by an existing customer.  Net sales in
the Public Safety segment decreased $829 thousand from $1.8 million in
2000 to $1.0 million in 2001.

CompuDyne's gross margin decreased $292 thousand in the third quarter of
2001 to $5.8 million, compared to $6.1 million in the third quarter of
2000.  The Corrections segment decreased $210 thousand to $3.4 million
for the third quarter 2001 from $3.6 million in 2000. The Attack
Protection segment increased $248 thousand to $1.5 million for the third
quarter of 2001 from $1.3 million for the third quarter of 2000. This
was due primarily to the addition of Fiber SenSys.  Gross margin for
the Federal Systems segment increased by $72 thousand from $516 thousand
in the third quarter of 2000 to $588 thousand in the third quarter of
2001.  The Public Safety segment decreased $402 thousand to $320 thousand
for the third quarter of 2001 from $722 thousand for the third quarter
of 2000.

CompuDyne's selling, general and administrative expenses decreased $144
thousand to $4.0 million for the third quarter of 2001 from $4.1 million
for the same period in 2000. The Corrections segment was $1.7 million for
the third quarter of 2001, a decrease of $594 thousand from $2.3 million
for the third quarter of 2000. The Attack Protection segment increased
selling, general and administrative expenses by $285 thousand to $931
thousand for the third quarter of 2001, from $646 thousand for the same
period in 2000. The Federal Systems segment selling, general and
administrative expenses were $202 thousand in the third quarter of 2001,
an increase of $22 thousand from $180 thousand in the third quarter of
2000. The Public Safety segment was $560 thousand for the third quarter
of 2001, a decrease of  $55 thousand from $615 thousand for the third
quarter of 2000.  CompuDyne corporate selling, general and administrative
expenses increased $197 thousand from $371 thousand in the third quarter
of 2000 to $568 thousand for the third quarter of 2001.  Although there
were slight increases and decreases by segment, selling, general and
administrative expense was 12.8% of sales in the third quarter of 2001

Interest expense was $697 thousand in the third quarter of 2001, an
increase of  $229 thousand from $468 thousand in the third quarter of
2000.  This increase is primarily a result of higher levels of
borrowings to fund the purchase of shares of Tiburon, Inc.

of  $12 thousand from $922 thousand in the third quarter of 2000.  Net
income for the Corrections segment increased $223 thousand to $665
thousand for the third quarter of 2001 from $442 thousand for the third

thousand for the third quarter of 2001, a decrease of $38 thousand from
$296 thousand for the same period in 2000.  The Federal Systems segment

thousand for the third quarter of 2001 from $28 thousand for the third

Year to Date 2001 and 2000 Comparison
-------------------------------------

Net sales for the Company were $92.5 million for the first nine months
of 2001, a decrease of $1.8 million from $94.4 million for the first nine
months of 2000. Sales in the Corrections segment were $57.8 million, a
decrease of  $5.6 million from $63.4 million in 2000.  This decrease is
primarily attributable to slower than anticipated output on several
projects at Norment due to temporary construction delays by the
Customers.  Net sales for the Attack Protection segment were $17.3
million in the first nine months of 2001, a decrease of $338 thousand
from $17.6 million for the same period in 2000.  Net sales for the
Federal Systems segment increased $4.6 million to $14.0 million in the
first nine months of 2001, from $9.4 million in the same period in 2000.
This increase is due to some large task orders awarded to Quanta Systems
by an existing customer. Sales in the Public Safety segment were $3.5
million, a decrease of  $444 thousand from $3.9 million in 2000.

CompuDyne's gross margin increased $139 thousand in the first nine
months of 2001 to $18.4 million, compared to $18.2 million in the first

$10.3 million for the first nine months of 2001 from $11.4 million in
2000. The Attack Protection segment increased $1.6 million to $5.0
million for the first nine months of 2001 from $3.3 million for the first
nine months of 2000. This was due to the addition of Fiber SenSys, and
improved gross margin at Sysco and Norshield. Gross margin for the
Federal Systems segment increased by $235 thousand from $1.5 million in
the first nine months of 2000 to $1.7 million in the first nine months of
2001 due to higher revenues. The Public Safety segment decreased $605
thousand to $1.3 million for the first nine months of 2001 from  $1.9
million for the first nine months of 2000.

CompuDyne's selling, general and administrative expenses increased $274
thousand to $12.8 million for the first nine months of 2001 from $12.5
million for the same period in 2000 primarily attributable to the
inclusion of Fiber SenSys which was acquired in November 2000.  The
Corrections segment was $6.2 million for the first nine months of 2001,
a decrease of  $928 thousand from $7.1 million for the first nine months
of 2000. The Attack Protection segment increased selling, general and
administrative expenses by $958 thousand to $2.8 million for the first
nine months of 2001, from $1.8 million for the same period in 2000. The

$634 thousand in the first nine months of 2001, an increase of $48
thousand from $586 thousand in the first nine months of 2000. The Public
Safety segment was $1.9 million for the first nine months of 2001, an
increase of  $89 thousand from $1.8 million for the first nine months of
2000.  CompuDyne corporate selling, general and administrative expenses
increased $107 thousand from $1.2 million in 2000 to $1.3 million in
2001.

Research and development costs were $62 thousand for the first nine
months of 2001, a decrease of $67 thousand from $129 thousand in 2000.
All research and development costs were incurred in the Federal Systems
segment for current product line improvements.

Interest expense was $1.8 million in the first nine months of 2001, an
increase of $252 thousand from $1.5 million in the first nine months of
2000.

Net income for the first nine months of 2001 was $2.7 million, an
increase of  $112 thousand from $2.5 million in the first nine months of
2000.  Net income for the Corrections segment decreased $83 thousand to
$1.5 million for the first nine months of 2001 from $1.6 million for the
first nine months of 2000. Net income for the Attack Protection segment
was $1.0 million for the first nine months of 2001, an increase of $387
thousand from $647 thousand for the same period in 2000.  The Federal
Systems segment net income increased $166 thousand to $475 thousand in
the first nine months of 2001, from $309 thousand for the first nine
months of 2000. Net income (loss) for the Public Safety segment
decreased $390 thousand to ($414) thousand for the first nine months of
2001 from ($24) thousand for the first nine months of 2000.  Unallocated
corporate office costs were $21 thousand in the first nine months of 2001
compared with ($12) thousand in the first nine months of 2000.

The Company had a backlog at September 30, 2001 of $131 million, an
increase of $14 million from $117 million at September 30, 2000.

LIQUIDITY AND CAPITAL RESOURCES

The Company funds its operations through cash flow generated from its
operations and bank financing. The Company's liquidity requirements
arise from cash to carry its inventories, costs in excess of billings,
billed and unbilled receivables, for payments of principal and interest
on outstanding indebtedness and for acquisitions.

As of September 30, 2001 the Company had working capital of $17.9
million compared with $16.6 million as of December 31, 2000.  At
September 30, 2001 the Company had a $10 million line of credit of which
$6.0 million was being used or was committed.

Net income of $2.7 million in the first nine months of 2001 resulted in
cash used in operations of $417 thousand. This compares with net income
in the first nine months of 2000 of $2.6 million and cash provided by
operations of $2.5 million.  The primary uses of cash were for the
increase in contract costs in excess of billings of $4.6 million and
decrease in billings in excess of costs of $1.4 million.  This was
partially offset by cash provided by payments from customers on accounts
receivable of $2.9 million.

Net cash used in investing activities was $6.1 million in the first nine
months of 2001 compared with $765 thousand used in investing activities
in the same period of 2000.  The Company used $6.0 million to purchase
Tiburon's common and preferred stock.

Net cash provided by financing activities was $6.6 million in the first
nine months of 2001 compared with $1.8 million used by financing
activities the first nine months of 2000.  In 2001, this included cash
provided by borrowings of $1.1 million from the line of credit, net new
borrowings totaling $7.0 million, and $2.5 million used to purchase
treasury stock.

The Company anticipates that cash generated from operations and
borrowings under its bank lines will enable the Company to meet its
liquidity, working capital and expenditure requirements. As discussed in
Note 6 to the consolidated financial statements, the Company has
exercised its option to merge with Tiburon subject to the approval of
the Company's shareholders and certain other considerations.  The merger
price is to be paid in shares of the Company's common stock.

The Company has approved an approximately $3 million capital expansion
program for the Company's Bullet, Blast and Attach protection division
as a result of a significant increase in inquiries, and the anticipated
order flow resulting from the events of September 11.  These capital

expenditures will be funded from the cash generated from the Company's
operations and borrowings under its bank lines.

On October 29, 2001 the Company completed the sale of 1.076 million new
common shares in a Private Investment to Public Equity transaction.  The
stock was sold at a price of $12.00 per share which netted the Company
approximately $12.0 million in new equity capital after fees and
expenses.

In this same transaction, the Company also arranged for the sale of
approximately 1.37 million CompuDyne common shares and shares underlying
warrants owned by William Blair Mezzanine Capital Partners II, L.P.
(the "Shareholder").  As a result of this transaction the Shareholder
realized approximately $12.8 million, and by agreement with the
Shareholder, the Company realized approximately $2.5 million in net
capital proceeds.  In addition, the Company realized approximately $1.0
million from the exercise of the Shareholder warrants.  The Company
utilized the proceeds of this offering to retire the $9 million, 13.15%
subordinated note held by the Shareholder and to pay down other bank
debt.  Since the $9 million subordinated debt was repaid prior to its
maturity, the Company incurred a $270 thousand (3%) prepayment fee.



QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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

CompuDyne has fixed and variable rate notes payable. These on-balance
sheet financial instruments, to the extent they provide for variable
rates of interest, expose the Company to interest rate risk, with the
primary interest rate exposure resulting from changes in the LIBOR rate
used to determine the interest rate applicable to the borrowings under
the Company's bank line of credit.

The information below summarizes CompuDyne's sensitivity to market risks
associated with fluctuations in interest rates as of September 30, 2001.
To the extent that the Company's financial instruments expose the Company
to interest rate risk, they are presented in the table below.  The
table presents principal cash flows and related interest rates by year of
maturity of the Company's notes payable with variable rates of interest
in effect at September 30, 2001.

The Company used a foreign exchange contract to partially hedge its
exposure to exchange rate risk related to one firmly committed sales
contract.  The foreign exchange contract was entered into for non-
trading purposes and was matched to the underlying transaction and did
not constitute speculative or leveraged positions independent of this
exposure.  As most of this contract has been completed, no significant
exchange risk exists as of September 30, 2001.
