Item 1.    Changes in Control of Registrant.

     On August 21, 1995, CompuDyne Corporation ("CompuDyne" or the "Company")
entered into and consummated a Stock Purchase Agreement by and among it, Martin
A. Roenigk and Alan Markowitz (Messrs. Roenigk and Markowitz are, collectively,
the "Sellers") and MicroAssembly Systems, Inc. ("MicroAssembly"), pursuant to
which CompuDyne issued to the Sellers 1,260,460 shares of its Convertible
Preference Stock, Series D ("Series D Preference Stock") in exchange for all of
the Sellers' shares of capital stock of MicroAssembly, which shares represent
all of MicroAssembly's issued and outstanding capital stock.  The issuance by
CompuDyne of the Series D Preferred Stock, together with the issuance of certain
Notes, as defined below, and certain options to purchase common stock, all as
described below and in accordance with the terms of the Stock Purchase
Agreement, are referred to as the "Transaction".  Of the 1,260,460 Shares of
Series D Preference Stock issued to the Sellers, 945,345 shares were issued to
Mr. Roenigk, and 315,115 shares were issued to Mr. Markowitz.  The Series D
Preference Stock has rights to vote on a share for share basis with the
Company's common stock on all corporate issues other than the election of
directors; it is also convertible to common stock on a share for share basis at
any time prior to redemption by the Company.  For the election of directors,
each share of Series D Preference Stock is entitled to 1/3.08 of a vote as
compared to the Company's common stock, which is entitled to one vote per
share. 


   As part of the Transaction, in return for $400,000 paid to CompuDyne at the
closing, CompuDyne issued to the Sellers Senior Convertible Promissory Notes
(the "Notes") in the aggregate principal amount of $400,000, which Notes are
convertible, prior to redemption by CompuDyne, into CompuDyne common stock at
a conversion rate of $1.50 per share of common stock, or 266,667 shares of
common stock if the entire principal amount of the Notes is converted.  Of the
$400,000 principal amount of Notes issued, $300,000 principal amount of the
Notes was issued to Mr. Roenigk, and $100,000 principal amount of the Notes was
issued to Mr. Markowitz.  As described in a report filed by the Sellers with the
Securities and Exchange Commission and with the Company pursuant to Section
13(d) of the Securities Exchange Act of 1934, the source of the Sellers'
$400,000 investment in the Company was personal funds.
     As a further part of the Transaction, Norman Silberdick, the Company's
Chairman, President and Chief Executive Officer, has resigned as such and as a
director of the Company.  The Company's Board of Directors has elected Mr.
Roenigk to fill Mr. Silberdick's seat on the Board of Directors, and to become
its Chairman, President and Chief Executive Officer.  Mr. Markowitz has also
been elected to the Company's six member Board of Directors.  In recognition of
Mr. Roenigk's position as Chairman, President and CEO, the Company has issued
to him options to purchase up to 200,000 shares of the Company's common stock
for $1.50 per share.  The options expire in ten (10) years.  Mr. Silberdick, as
part of a related transaction described in Item 2 of this report, has turned in
to the Company 60,000 shares of the Company's common stock issued pursuant to
a Stock Purchase Agreement, dated August 1, 1993, between the Company and Mr.
Silberdick, and he has relinquished his rights to purchase an additional 50,000
shares pursuant to such Agreement.
     Immediately prior to the Transaction, but after the exercise by Corcap,
Inc. ("Corcap") of a warrant to acquire 150,000 shares of CompuDyne common
stock, Corcap held 670,881 shares of CompuDyne's voting shares, or approximately
38.3% of CompuDyne's 1,749,622 issued and outstanding shares of Common Stock. 
After the transactions described above, Corcap's 670,881 shares now represent
approximately 22.3% of the voting power of issued and outstanding shares
(including the Series D Preference Stock) on all issues other than the election
of directors, 30.2% of the voting power of issued and outstanding shares for the
election of directors, and approximately 18.8% of the voting shares on a fully
diluted basis.
     Prior to the Transaction, the Sellers held no voting shares of CompuDyne,
although Mr. Roenigk held 70,000 shares of Corcap common stock, which is
approximately 2.4% of Corcap's voting shares.  Immediately after the
Transaction, the Sellers held 1,260,460 shares of CompuDyne's voting stock
(including the Series D Preference Stock), or approximately 41.9% of the voting
power of issued and outstanding shares for all issues other than the election
of directors and 19% of the voting power of issued and outstanding shares for
the election of directors.  Assuming conversion by the Sellers of all of the
shares of Series D Preference Stock, the conversion of the full principal amount
of the Notes and the exercise by Mr. Roenigk of his options to purchase 200,000
shares of the Company's Common Stock, the Sellers would hold 1,727,127 shares
of the Company's voting stock, or approximately 48.5% of the Company's voting
stock on a fully diluted basis.  In addition, in connection with the
Transaction, Mr. Roenigk became a director of Corcap and was issued options to
purchase 450,000 additional shares of Corcap common stock which, if exercised,
would, together with Mr. Roenigk's prior holdings, result in his holding
approximately 15.4% of Corcap's common stock.
     The Sellers have, in their filing with the Securities and Exchange
Commission pursuant to Section 13(d) of the Securities and Exchange Act of 1934,
disclaimed any arrangements or understandings among themselves or their
associates with respect to the future election of the Company's directors or
other matters in connection with the operation and management of the Company. 
Upon consummation of the transaction in addition to Mr. Roenigk, CompuDyne's
executive officers are, respectively, Philip M. Blackmon, Vice President, and
Elaine Chen, Treasurer and Chief Financial Officer.

Item 2.  Acquisition or Disposition of Assets.
I.   Acquisition of MicroAssembly Systems, Inc. Common Stock.
     In connection with the Stock Purchase Agreement, the Company acquired on
August 21, 1995 all of the capital stock of MicroAssembly (the "MicroAssembly
Stock") from the Sellers.  MicroAssembly, located in Willimantic, Connecticut,
is a manufacturer of a proprietary automated process called the "Stick-Screw
System".  The Stick-Screw System uses custom designed screws in a stick format
for the insertion of fasteners in electronic and other assembly environments. 
The Stick-Screw System provides for insertion of the fasteners at a faster speed
than can be accomplished by competing systems or processes.  MicroAssembly
operates out of owned facilities, utilizing automatic screw machines to
manufacture the Stick-Screws.  MicroAssembly also manufactures the specially
designed pneumatic drivers for inserting the screws.  Sales are primarily
throughout the United States via a network of independent sales representatives,
with modest sales in Europe and South America.
     The consideration to the Sellers for the MicroAssembly Stock was the
issuance to them of 1,260,460 shares of CompuDyne's Series D Preference Stock. 
Each share of Series D Preference Stock carries an annual aggregate dividend
equal to the lower of:  (a) sixty percent (60%) of MicroAssembly's after-tax net
income in the previous calendar year, divided by 1,260,460, or (b) eight percent
(8%) of the Redemption Value of $1.50 per share of the Series D Preference
Stock.  Dividends may be paid on the Series D Preference Stock, at the Company's
option, in cash, CompuDyne common stock, or a combination thereof, based upon
the average closing price of CompuDyne's common stock for the prior thirty (30)
trading days as quoted on a national securities exchange or, if not so quoted,
on the NASDAQ, or if not so quoted, on the OTC Bulletin Board maintained by the
NASD, or, if not so quoted, by the average closing bid prices quoted by three
dealers regularly making a market or maintaining bid and asked prices on such
stock (or such fewer number of dealers which may be making a market or
maintaining bid and asked prices).
     Beginning on August 21 in the year 2000, the Company may, at its option,
redeem all or any part of the Series D Preference Stock for a price of $1.80 per
share, that being one hundred twenty percent (120%) of the Redemption Value,
plus accrued and unpaid dividends.  Beginning on August 31, 2006, and on that
date in each of the four succeeding years, the Company shall redeem 252,092
shares of Series D Preference Stock, or such lesser number as may be issued and
outstanding, for their $1.50 per share Redemption Value.
     The Company reviewed the recent financial performance of MicroAssembly,
visited the manufacturing facilities, evaluated management, and considered the
strong balance sheet of MicroAssembly in coming to the determination of the
consideration to be paid.  The Company considered both the value of
MicroAssembly and the ability of MicroAssembly and its shareholders to bring
considerable additional financial strength to CompuDyne's operations.

II.  Disposition of the Assets and Liabilities of the Suntec Division.
     On August 21, 1995, Quanta Systems Corporation ("Quanta"), a wholly-owned
subsidiary of CompuDyne, transferred all of the assets and liabilities of
Quanta's Suntec division to Suntec Service Corporation, a newly-formed
corporation ("Suntec"), in return for (i) all of Suntec's issued and outstanding
common stock and (ii) Suntec's agreement to pay to Quanta a royalty of 2% of
Suntec's net sales and other revenues for thirty (30) years from the date of the
closing.  Quanta then sold all of Suntec's common stock to Norman Silberdick,
who resigned on that date as CompuDyne's Chairman, President, CEO and Director. 
Suntec is engaged in the business of tele-marketing home improvements in the
middle Atlantic states, primarily in the Baltimore, Maryland and Washington,
D.C., area from leased offices in Gaithersberg, Maryland.  Suntec helps arrange
home improvement financing for homeowners and provides the home improvement
services through subcontractors located in its market area.
     As consideration for the shares of Suntec, Mr. Silberdick executed a
nonrecourse promissory note in the initial principal amount of $79,000 (the
"Silberdick Note"), payment of which is secured by a pledge of all Suntec shares
held by Mr. Silberdick, which shares must at all times equal or exceed 33% of
all outstanding shares of Suntec capital stock.  The Silberdick Note bears
interest at an annual rate equal to the Wall Street Journal prime rate, plus 
2%.  Through August 31, 2000, the principal of the Silberdick Note is payable
annually in amounts equal to 25% of Suntec's net, after-tax income for the year
in question.  Thereafter, the unpaid principal balance, as of that date, shall
be paid in five equal annual installments.
     As a condition precedent to the sale of the Suntec shares to Mr.
Silberdick, he turned in to CompuDyne 60,000 shares of CompuDyne Common Stock
and relinquished purchase rights held by him to acquire an additional 50,000
shares of additional CompuDyne Common Stock.
     The amount of consideration determined by Quanta to be appropriate for the
sale of the Suntec common stock to Mr. Silberdick resulted from a number of
factors.  While a division of Quanta, Suntec's business had never produced a
profit.  As a result, and in light of Quanta's retention of the 2% royalty on
Suntec's net sales and other revenues for 30 years, Quanta decided that the
business should be valued at its net book value at the Closing Date.  The amount
of the Silberdick Note was, at the Closing Date, based upon Suntec's net book
value at June 30, 1995 and is subject to adjustment to its net book value based
upon a Closing Date balance sheet to be completed on or before September 20,
1995.

NOTES:

1.  The pro forma adjustments were calculated assuming the disposition of
    Suntec operations was consummated at the beginning of fiscal year 1994.

2.  Suntec division was operated in a separate building with personnel
    separate from other operations.  Therefore the adjustments for the
    disposition involve mainly the revenue and cost incurred directly related
    to the Suntec Division.  Other effects of the disposition were immaterial
    and not considered in this report.

3.  No Income Tax Provision is shown against the resulting net income; there
    are sufficient credits from loss-carry-forwards to offset any required
    tax provision.

NOTES:

1.  The pro forma adjustments were calculated assuming the disposition of
    Suntec operations was consummated at the beginning of fiscal year 1994.

2.  Suntec division was operated in a separate building with personnel
    separate from other operations.  Therefore the adjustments for the
    disposition involve mainly the revenue and cost incurred directly related
    to the Suntec Division.  Other effects of the disposition were immaterial
    and not considered in this report.

3.  No additional Income Tax Provision is shown against the resulting net
    income: there are sufficient credits from loss-carry-forwards to offset
    any required tax provision.

                       Pursuant to Section 602 of the 
                    Pennsylvania Business Corporation Law

                _____________________________________________


     COMPUDYNE CORPORATION, a corporation organized and existing under the laws
of the State of Pennsylvania (the "Corporation"), hereby certifies that the
following resolution was duly adopted by the Board of Directors of the
Corporation at a meeting duly called and held on August 18, 1995, at which
meeting a quorum of the directors was present and acting throughout:

     RESOLVED that, pursuant to authority expressly vested in the Board of
Directors of the Corporation by the provisions of the Articles of Incorporation
of the Corporation, as amended, the Board of Directors of the Corporation hereby
provides for the issuance of a series of preference stock of the Corporation,
without par value, to consist of 1,260,460 shares, and hereby fixes the powers,
designation, preferences and relative, participating, optional or other rights
of such series of preference stock, and the qualifications, limitations and
restrictions thereof, as follows:

     l.   Designation.

          (a)  The designation of the series of preference stock created by
     this resolution shall be Convertible Preference Stock, Series D
     (hereinafter called "Series D Preference Stock"), and the number of shares
     constituting the Series D Preference Stock upon original issuance is
     1,260,460.

          (b)  Any shares of the Series D Preference Stock which at any time
     have been redeemed, purchased or otherwise acquired by the Corporation
     shall, after such redemption, purchase or other acquisition, have the
     status of authorized but unissued shares of preference stock, without
     designation as to series until such shares are once more designated as
     part of a particular series by the Board of Directors of the Corporation.

     2.   Payment of Dividends.

          (a)  The holders of record of shares of the Series D Preference Stock
     shall be entitled to receive, as and when declared by the Board of
     Directors of the Corporation out of funds legally available therefor, cash
     dividends thereon at the Applicable Rate (as defined below) per annum, and
     no more, payable on the respective dates set forth below.  The Series D
     Preference Stock shall not participate in any other dividends.  

          (b)  Dividends on the Series D Preference Stock shall accrue at the
     Applicable Rate in effect on the most recent Dividend Payment Date and
     shall be cumulative from the date of original issuance of the Series D
     Preference Stock (the "Original Issuance Date").

          (c)  Accrued dividends shall be payable annually on the fifteenth day
     following the delivery of audited financial statements (the "Audited
     Financials") to the Board of Directors of the Corporation by the
     Corporation's independent auditors (the "Independent Auditors") for the
     prior year, but in no event later than April 15 of each year ("Dividend
     Payment Date"), commencing on the Dividend Payment Date in 1996; provided,
     however, that if any Dividend Payment Date would otherwise be a day that
     is not a Business Day (as defined below), the Dividend Payment Date shall
     be postponed to the next day that is a Business Day.  The period beginning
     on the Original Issuance Date and ending on the first Dividend Payment
     Date and each successive period beginning on the first day after each
     Dividend Payment Date and ending on the next succeeding Dividend Payment
     Date is herein called a "Dividend Period."  As used herein, "Business Day"
     means any day, other than a Saturday or Sunday or a day on which
     commercial banks in Hartford, Connecticut are required or authorized by
     law, regulatory order or executive order to be closed.

          (d)  The rate of dividends per annum payable on the Series D
     Preference Stock for each Dividend Period (the "Applicable Rate") per
     share shall be equal to the lower of:  (a) sixty percent (60%) of the
     after tax net income of MicroAssembly Systems, Inc. ("MicroAssembly"), a
     wholly-owned subsidiary of the Corporation, in the previous calendar year,
     on an unconsolidated basis with the Corporation, based on the Audited
     Financials, divided by the number of shares of Series D Preference Stock
     originally issued as set forth in Section 1(a) hereof; or (b) eight
     percent (8%) of the Redemption Value (as hereinafter defined) of a share
     of Series D Preference Stock.  Notwithstanding the foregoing, on the first
     Dividend Payment Date only, the applicable rate shall be equal to the
     lower of (a) sixty percent (60%) of the after-tax net income of
     MicroAssembly, on an unconsolidated basis with the Corporation, for the
     period in 1995 during which the Corporation owned one hundred percent
     (100%) of MicroAssembly's outstanding stock (the "Period of Ownership"),
     based on the Audited Financials, divided by the number of shares of
     Series D Preference Stock originally issued as set forth in Section 1(a)
     hereof; or (b) the product obtained by multiplying (i) eight percent (8%)
     of the Redemption Value of a share of Series D Preference Stock by (ii) a
     fraction the numerator of which is the number of days from the Original
     Issuance Date to and including December 31, 1995 and the denominator of
     which is 365.

          (e)  Dividends may be paid in cash or in shares of common stock, par
     value $0.75 per share (the "Common Stock"), of the Corporation, or a
     combination thereof, solely at the option of the Corporation.  If the
     dividends, or a portion thereof, are paid in Common Stock, the value of
     the Common Stock shall be based upon the average closing bid price for the
     Common Stock for the prior thirty (30) trading days as quoted on a
     national securities exchange or, if not so quoted, on the NASDAQ, or, if
     not so quoted, on the OTC Bulletin Board, an inter-dealer quotation medium
     maintained by the National Association of Securities Dealers, Inc., or if
     not so quoted, by the average closing bid prices quoted by three dealers
     regularly making a market or maintaining bid and asked prices on the
     Common Stock (or such fewer number of dealers which may be making a market
     or maintaining bid and asked prices).  

          The Corporation shall calculate the Applicable Rate, the dividends
     payable on the Series D Preference Stock and, if the dividends, or a
     portion thereof, are paid in shares of Common Stock, the value of the
     Common Stock.  Any and all disputes between the Corporation and any holder
     of the Series D Preference Stock with regard to such calculations shall be
     resolved by the Independent Auditors, which resolution shall be final and
     binding on the Corporation and such holders.  The fees and expenses of the
     Independent Auditors in resolving such calculations shall be paid by the
     Corporation.

     3.   Priority as to Dividends. 

          (a)  No dividends may be declared or paid on the Common Stock of the
     Corporation unless and until all accrued dividends on the Series D
     Preference Stock have been declared and paid.  If there are one or more
     series or classes of preferred stock or preference stock outstanding of a
     priority equal to the Series D Preference Stock, and if there are any
     accrued and unpaid dividends with respect to any such series or class, any
     dividends in an amount less than the full cumulative dividends accrued and
     payable, to be declared and paid with respect to the preferred stock and
     preference stock shall be distributed among the different series or
     classes of preferred stock and preference stock in the same proportion
     that the dividends accrued and payable with respect to such series or
     classes bears to the aggregate accrued and payable dividends for all
     series or classes of preferred stock and preference stock of the
     Corporation.
     
          (b)  If dividends in full on all outstanding shares of the Series D
     Preference Stock for all prior Dividend Periods and the current Dividend
     Period have not been paid or been declared and set apart for payment, (i)
     the Corporation may not call for redemption any shares of the Series D
     Preference Stock unless all shares of the Series D Preference Stock
     outstanding are called by the Corporation and (ii) the Corporation may not
     call for redemption any shares of any class of stock ranking on a parity
     with or junior to the Series D Preference Stock.

     4.   Redemption.

          (a)  Commencing five years after the Original Issuance Date, the
     shares of Series D Preference Stock may be redeemed, as a whole at any
     time, or in part from time to time, at the election of the Corporation
     ("Optional Redemption") by resolution of its Board of Directors, out of
     funds legally available therefor, at a redemption price of one hundred and
     twenty percent (120%) of the Redemption Value per share of the Series D
     Preference Stock plus accrued and unpaid dividends, including a partial
     dividend to the date of redemption; provided, however, that no Optional
     Redemption may be declared or paid by the Corporation unless and until all
     accrued dividends of the Series D Preference Stock have been declared and
     paid.  The redemption value of the Series D Preference Stock shall be
     $1.50 per share (the "Redemption Value").  

          (b)  On August 31 in each of the years 2006, 2007, 2008, 2009 and
     2010 the Corporation shall redeem ("Mandatory Redemption") 252,092 shares
     of Series D Preference Stock or such lesser number as may be issued and
     outstanding, at a redemption price per share equal to the Redemption
     Value.  The shares of Series D Preference Stock to be so redeemed will be
     selected by lot.

          (c)  Notice of any redemption, specifying the date fixed for said
     redemption and the place where the amount to be paid upon redemption is
     payable (the "Notice of Redemption"), shall be mailed, postage prepaid at
     least ninety (90) days but not more than one hundred and twenty (120)
     days, in the case of Optional Redemption, and at least thirty (30) days
     but not more than sixty (60) days, in the case of Mandatory Redemption,
     prior to said redemption date to each holder of record of the Series D
     Preference Stock to be so redeemed at his address as the same shall appear
     on the books of the Corporation.  The Notice of Redemption shall include
     (i) the redemption date; (ii) the number of shares of the Series D
     Preference Stock to be redeemed and, if fewer than all shares held by such
     holder are to be redeemed, the number of shares to be redeemed from such
     holder; (iii) the redemption price; (iv) the place or places where
     certificates for such shares are to be surrendered for payment of the
     redemption price; and (v) a statement that dividends on the shares to be
     redeemed will cease to accrue on such redemption date.  

          If such Notice of Redemption shall have been so mailed, and none of
     the holders of shares of Series D Preference Stock shall have elected to
     convert such shares into Common Stock within the time periods set forth in
     Section 7(c) hereof, and if on or before the redemption date specified in
     such notice all funds necessary for such redemption shall have been
     irrevocably deposited in trust, for the account of the holders of the
     shares of Series D Preference Stock to be redeemed (and so as to be and
     continue to be available therefor), with a bank or trust company named in
     such notice doing business in the State of Connecticut and having a
     combined capital and surplus of at least $100,000,000, thereupon and
     without awaiting the redemption date, notwithstanding that any certificate
     for shares of the Series D Preference Stock so called for redemption shall
     not have been surrendered for cancellation, the shares represented thereby
     so called for redemption shall be deemed to be no longer outstanding and
     all obligations to redeem and retire each share shall be deemed satisfied,
     the right to receive dividends thereon shall cease to accrue, and all
     rights with respect to such shares of Series D Preference Stock so called
     for redemption shall forthwith upon such deposit in trust cease and
     terminate, except only the right of the holders thereof to receive out of
     the funds so set aside in trust, the amount payable on redemption thereof,
     but without interest.

          In case the holders of shares of the Series D Preference Stock which
     shall have been called for redemption shall not within four years (or any
     longer period if required by law) after the redemption date claim any
     amount so deposited in trust for the redemption of such shares, such bank
     or trust company shall, upon demand and if permitted by applicable law,
     pay over to the Corporation any such unclaimed amount so deposited with
     it, and shall thereupon be relieved of all responsibility in respect
     thereof, and thereafter the holders of such shares shall, subject to
     applicable escheat laws, look only to the Corporation for payment of the
     redemption price thereof but without interest.

          (d)  Upon surrender of the certificates for shares of Series D
     Preference Stock for redemption, in accordance with the Notice of
     Redemption, such shares shall be redeemed by the Corporation at the
     applicable redemption price.  In case fewer than all the shares
     represented by any such certificate are to be redeemed, a new certificate
     shall be issued representing  the unredeemed shares, without cost to the
     holder of the shares.

     5.   Liquidation Rights. 

          (a)  In the event of the voluntary liquidation, dissolution or
     winding up of the Corporation, the holders of shares of Series D
     Preference Stock then outstanding shall be entitled to receive, before any
     distribution or payment shall be made in respect of the Common Stock or
     any other stock of the Corporation ranking junior to the Series D
     Preference Stock as to distribution of assets on liquidation, dissolution
     or winding up, an amount per share equal to the Redemption Value set forth
     in Section 4(a) above plus all accrued but unpaid dividends, provided that
     the holders of the Series D Preference Stock then outstanding shall be
     entitled to no further participation in any distribution or payment in
     connection with any such liquidation, dissolution or winding up.

          (b)  In the event of any involuntary liquidation, dissolution or
     winding up of the Corporation, the holders of shares of Series D
     Preference Stock then outstanding shall be entitled to receive out of the
     assets of the Corporation available for distribution to stockholders, but
     before any distribution or payment shall be made in respect of the Common
     Stock or any other stock of the Corporation ranking junior to the Series
     D Preference stock as to distribution of assets on liquidation,
     dissolution or winding up, an amount equal to the Redemption Value set
     forth in Section 4(a) above, but the holders of the Series D Preference
     Stock shall be entitled to no further participation in any distribution or
     payment in connection with any such liquidation, dissolution or winding
     up.

          (c)  If, upon any voluntary or involuntary liquidation, dissolution
     or winding up of the Corporation, the assets of the Corporation available
     for distribution among the holders of all outstanding shares of Series D
     Preference Stock and of any other stock of the Corporation ranking on a
     parity with the Series D Preference Stock as to assets on liquidation,
     shall be insufficient to permit the payment in full to such holders of the
     amounts to which they are entitled, then such available assets shall be
     distributed among the holders of Series D Preference Stock and of any
     other stock of the Corporation ranking upon a parity with the Series D
     Preference Stock as to distribution of assets on liquidation ratably in
     proportion to the full preferential amounts to which they would otherwise
     respectively be entitled.

          (d)  Neither the consolidation or merger of the Corporation with or
     into any other corporation or corporations, nor the sale or transfer by
     the Corporation of all or any part of its assets, shall be deemed to be a
     liquidation, dissolution or winding up of the Corporation for purposes of
     this Section.

     6.   Voting Rights. 

          (a)  Except as otherwise required by law, in connection with all
     matters to be voted upon by the Corporation's shareholders, all holders of
     Capital Stock shall vote together as a single class.  With respect to the
     election of directors, each share of Common Stock issued and outstanding
     shall have one vote and, subject to the provisions of this Section 6(a),
     each share of Series D Preference Stock issued and outstanding shall have
     1/3.08 of a vote or such lesser or greater fraction to enable the holders
     thereof to cast 19% of the total number of votes that all shareholders
     would be entitled to cast in an election of directors of the Corporation
     including votes that such holders would be entitled to cast as record
     holders of any other shares of the Corporation, provided that in no event
     shall a share of Series D Preference Stock have more than one vote per
     share.  Notwithstanding the foregoing, each share of Series D Preference
     Stock issued and outstanding shall have one vote with respect to the
     election of directors, effective as of August 1, 1996, unless the Board of
     Directors of the Corporation, in its sole and absolute discretion,
     approves a resolution prior to such date prohibiting such change in voting
     rights, in which case each share of Series D Preference Stock issued and
     outstanding will continue to have 1/3.08 vote per share with respect to
     the election of directors, or such lesser or greater fraction as provided
     above.  In the event the Board approves such a resolution, on May 1 of
     each subsequent year (until each share of Series D Preference Stock has
     one vote with respect to the election of directors), each share of Series
     D Preference Stock shall have one vote, effective as of such date, unless
     the Board of Directors of the Corporation approves a resolution prior to
     such date prohibiting such change in voting rights.  

          With respect to all other matters to be voted upon by the
     Corporation's shareholders, each share of Common Stock issued and
     outstanding shall have one vote and each share of Series D Preference
     Stock issued and outstanding shall have one vote in addition to those
     rights herein specifically accorded to Series D Preference Stock herein
     and in the Articles of Incorporation of the Corporation.

          (b)  (i)  If at the time of any meeting of shareholders called for
     the election of directors, any one or more annual dividends (whether or
     not consecutive) payable on the Series D Preference Stock shall be in
     arrears, or if a mandatory redemption payment on any outstanding Series D
     Preference Stock has been omitted, the holders of the outstanding Series D
     Preference Stock, voting as a single class, shall thereafter have the
     right to elect a majority of the directors.  Such voting rights shall
     remain vested until such time as all dividends in arrears on the Series D
     Preference Stock or the mandatory redemption payment, the omission of
     which gave rise to such voting rights, have been paid or declared and a
     sum sufficient therefor set apart for payment, at which time the right
     shall terminate (subject to revesting) and upon any termination of the
     aforesaid voting right, subject to the requirements of the Corporation's
     Articles of Incorporation, as amended, all directors elected by the
     holders of the Series D Preference Stock, voting separately as a class,
     are to resign.  

               (ii) A director elected by the holders of the Series D
     Preference Stock pursuant to Section 6(b)(i) above (a "Preference
     Director") may be removed only for cause, and only by the affirmative vote
     of the holders of record of seventy-five percent (75%) of the Series D
     Preference Stock.

          (c)  So long as any shares of the Series D Preference Stock remain
     outstanding, the Corporation may not, without the affirmative vote or
     consent of the holders of at least two-thirds of the then outstanding
     shares of Series D Preference Stock, (i) authorize stock ranking prior to
     the Series D Preference Stock as to dividends or as to distribution of
     assets; or (ii) increase the authorized number of shares of any class of
     stock ranking prior to the Series D Preference Stock as to dividends or as
     to distribution of assets; or (iii) amend, repeal or change any of the
     provisions of the Articles of Incorporation, as amended, respecting any
     stock of the Corporation or to authorize any reclassification of the
     Series D Preference Stock so as to adversely affect the preferences,
     special rights or powers of the Series D Preference Stock, either directly
     or indirectly or through a merger or consolidation with any corporation. 
     So long as any shares of the Series D Preference Stock are outstanding,
     the Corporation may not, without the affirmative vote or consent of the
     holders of at least a majority of the then outstanding shares of
     Preference Stock, voting separately as a class, increase the number of
     authorized shares of Preference Stock or create, or increase the
     authorized number of shares of, any other series or class of capital stock
     of the Corporation ranking on a parity with the Preference Stock as to
     dividends or distribution of assets.

     7. Conversion. 

          (a)  Series D Preference Stock shall be convertible at the option of
     the record holder thereof at any time after the Original Issuance Date
     into fully paid and nonassessable shares of Common Stock of the
     Corporation (rounded to the nearest, or if there shall be no nearest, then
     to the next lower whole share of Common Stock) at the rate of one share of
     Common Stock for each Series D Preference share.  The minimum number of
     Series D Preference shares eligible for conversion at any one time by any
     one holder shall be one thousand (1,000) shares.  Upon conversion of any
     shares of Series D Preference Stock, subject to Section 2 above, the
     holder thereof shall be entitled to the amount of any dividends accrued
     and unpaid with respect to such shares through the Dividend Payment Date
     next preceding the Conversion Date (as defined in Section 7(c) hereof);
     such dividends shall be payable on the Conversion Date.  With respect to
     the period from such Dividend Payment Date through the Conversion Date,
     the holder of the shares of Series D Preference Stock to be converted
     shall be entitled to the amount of any dividends accrued and unpaid with
     respect to such shares on the Dividend Payment Date next succeeding the
     Conversion Date prorated to the Date of Conversion; such dividends shall
     be payable on the Dividend Payment Date next succeeding the Conversion
     Date.

          (b)  The conversion rate shall be subject to the following
     adjustments:

               (i)  In case the Corporation shall declare and pay a dividend in
     shares of Common Stock, the conversion rate in effect immediately prior to
     the time fixed for the determination of stockholders entitled to such
     dividend shall be proportionately increased (adjusted to the nearest or,
     if there shall be no nearest, then to the next lower, one-hundredth of a
     share of Common Stock), such adjustment to become effective immediately
     after the time fixed for such determination.

               (ii) In case the Corporation shall subdivide the outstanding
     shares of Common Stock into a greater number of shares of Common Stock or
     combine the outstanding shares of Common Stock into a smaller number of
     shares of Common Stock, the conversion rate in effect immediately prior to
     such subdivision or combination, as the case may be, shall be
     proportionately increased or decreased (adjusted to the nearest, or if
     there shall be no nearest, then to the next lower, one-hundredth of a
     share of Common Stock), as the case may require, such increase or decrease
     to become effective when such subdivision or combination becomes
     effective.

             (iii)  In case of any reclassification or change of outstanding
     shares of Common Stock, or in case of any consolidation or merger of the
     Corporation with or into another corporation, or in case of any sale or
     conveyance to another corporation of all or substantially all of the
     property of the Corporation, the holder of such Series D Preference Stock
     then outstanding shall have the right thereafter, so long as his
     conversion right hereunder shall exist, to convert such shares into the
     kind and amount of shares of stock and other securities and property
     receivable upon such reclassification, change, consolidation, merger, sale
     or conveyance by a holder of the number of shares of Common Stock of the
     Corporation into which such Series D Preference Stock might have been
     converted immediately prior to such reclassification, change,
     consolidation, merger, sale or conveyance, and shall have no other
     conversion rights under these provision; and, effective provisions, if
     required, shall be made in the Articles or Certificate of Incorporation of
     the resulting, surviving or successor corporation or otherwise, so that
     the provisions set forth herein for the protection of the conversion
     rights of the holders of the Series D Preference shares shall hereafter be
     applicable, as nearly as reasonably may be, to any such other shares of
     stock and other securities and property deliverable upon conversion of the
     Series D Preference shares remaining outstanding or other convertible
     preferred or preference shares received by the holders in place thereof;
     and any such resulting, surviving or successor corporation shall expressly
     assume the obligations to deliver, upon the exercise  of the conversion
     privilege, such shares, securities, or property as the holders of the
     Series D Preference Stock remaining outstanding, or other convertible
     preferred or preference shares received by the holders in place thereof,
     shall be entitled to receive pursuant to the provisions hereof, and to
     make provision for the protection of the conversion rights as above
     provided.  In case securities or property other than shares of Common
     Stock shall be issuable or deliverable upon conversion as aforesaid, then
     all references in this section shall be deemed to apply so far as
     appropriate and as nearly as may be, to such other securities or property. 
     The subdivision or combination of shares of Common stock at anytime
     outstanding into a greater or lesser number of shares of Common Stock
     (whether with or without par value) shall not be deemed to be a
     reclassification of the Common Stock of the Corporation for the purposes
     of this subsection (iii).
 
          (c)  In order to convert Series D Preference shares into shares of
     Common Stock, the holder thereof shall give at least thirty (30) days' but
     not more than ninety (90) days' written notice to the Corporation at the
     office of the Corporation (or such other place as may be designated by the
     Corporation) that the holder elects to convert the same and shall state in
     writing therein the name or names in which he wishes the certificate or
     certificates for shares of Common Stock to be issued and shall surrender
     the certificate or certificates for the Series D Preference shares, duly
     endorsed to the Corporation in blank, at said office of the Corporation. 
     The Corporation shall, as soon as practicable thereafter, deliver at said
     office to such holder of Series D Preference Stock, or to his nominee or
     nominees, a certificate or certificates for the number of full shares of
     Common Stock to which he shall be entitled.  Series D Preference Stock
     shall be deemed to have been converted as of the date of the surrender of
     such stock for conversion as provided in this Section 7(c) (the
     "Conversion Date"), and the person or persons entitled to receive the
     shares of Common Stock issuable upon such conversion shall be deemed for
     all purposes to be the record holder or holders of such Series D
     Preference shares on such date.  

          A number of authorized shares of Common Stock sufficient to provide
     for the conversion of the Series D Preference Stock outstanding upon the
     basis of this Section 7 shall at all times be reserved for such
     conversion.

     8.   Preemptive Rights.

          (a)  Upon the offering or sale by the Corporation for cash of its
     shares of Common Stock or any security convertible into shares of Common
     Stock, including warrants, rights to subscribe and options to acquire
     shares of Common Stock (collectively, "Convertible Securities"; such
     shares and Convertible Securities are collectively referred to in this
     Section 8 as the "Securities"), each holder of Series D Preference Stock
     shall have the preemptive right, subject to the provisions of this Section
     8, to receive or purchase up to that amount of Securities which would
     maintain his percentage ownership interest in the Common Stock, assuming
     conversion of the Series D Preference Stock, after the issuance of the
     Securities on a fully diluted basis as existed prior to the issuance of
     the Securities.  As used in this Section 8, the term "fully diluted basis"
     shall mean the calculation of percentage ownership based upon all
     outstanding shares of Common Stock plus the assumed issuance of Common
     Stock then issuable upon conversion of the Series D Preference Stock and
     any other security, including the Convertible Securities, convertible into
     shares of Common Stock, including warrants, rights to subscribe and
     options to acquire shares of Common Stock.  Notwithstanding the foregoing,
     the holders of Series D Preference Stock shall not have preemptive rights
     with respect to shares or Convertible Securities (a) that are offered,
     sold or issued to directors or employees of the Corporation or any of its
     wholly-owned subsidiaries, (b) that were issued or authorized prior to the
     Original Issuance Date, (c) that were issued on the conversion of
     Convertible Securities and such Convertible Securities were offered or
     issued to the holders of Series D Preference Stock in satisfaction of this
     Section 8, or (d) that are issued in connection with a merger or
     consolidation or a proceeding under the Federal Bankruptcy Act, as
     amended, or pursuant to an order of a court of competent jurisdiction
     unless such order otherwise provides.

          (b)  Notice.  Prior to any issuance by the Corporation of any
     Securities, the Corporation shall notify each holder of Series D
     Preference Stock, in writing, of his intention to issue such Securities,
     setting forth the terms under which he proposes to make such issuance. 
     Within thirty (30) days after receipt of such notice, each holder of
     Series D Preference Stock shall notify the Corporation as to the amount of
     Securities so offered that such holder desires to purchase.  The holders
     of Series D Preference Stock shall receive or purchase and the Corporation
     shall issue and/or sell the Securities at the same time, and upon the same
     terms and conditions, as the Securities are issued or sold.  The
     Corporation shall take all such action as may reasonably be required by
     any regulatory authority in connection with the exercise by a holder of
     Series D Preference Stock of the right to receive or purchase Securities
     as set forth in this Section 8.

     9.   Exclusion of Other Rights.  

          Except as may otherwise be required by law, the shares of Series D
     Preference Stock shall not have any preferences, or relative,
     participating, optional or other special rights, other than those
     specifically set forth in this resolution and in the Articles of
     Incorporation, as amended, of the Corporation.  The shares of Series D
     Preference Stock shall have no preemptive or subscription rights except as
     provided herein.

                     SENIOR CONVERTIBLE PROMISSORY NOTE


$300,000                                                      August 21, 1995

      1.  FOR VALUE RECEIVED, the undersigned COMPUDYNE CORPORATION, a 
Pennsylvania corporation (the "Maker"), promises to pay to the order of MARTIN 
ROENIGK (the "Holder") an individual residing at 26 Barton Hill, East 
Hampton, Connecticut 06424 or at such other place as the Holder hereof may 
designate, in lawful money of the United States, the principal sum of THREE 
HUNDRED THOUSAND DOLLARS ($300,000), together with interest on the unpaid 
balance of this Note, beginning on the date hereof, before maturity, default 
or judgment, at two percent (2%) above the variable annual rate equal to the 
rate published from time to time in The Wall Street Journal (Eastern Edition) 
("WSJ-EE") as the "Prime Rate" (the base rate on corporate loans posted by at 
least seventy-five percent (75%) of the nation's thirty (30) largest banks) 
(the "Prime Rate").  The interest rate will be adjusted upward or downward, 
as of the date of a change in the Prime Rate; provided, however, that at no 
time shall the interest rate be more than the rate permitted by applicable 
law.  The Prime Rate is not necessarily the lowest rate available.  In the 
event that the "Prime Rate" is no longer published from time to time by 
WSJ-EE, then the term "Prime Rate" shall mean the variable rate of interest 
published or publicly promulgated from time to time by the WSJ-EE or some 
other entity generally recognized in the financial community as reputable
and authoritative, determined by the Holder, in its sole discretion, most 
nearly approximate to the base rate on corporate loans posted by at least 
seventy-five percent (75%) of the nation's thirty (30) largest banks. 
Interest under this Note shall be computed daily on the basis of a 360-day 
year and the actual number of days elapsed, together with (a) all taxes 
levied or assessed against the Holder of this Note or the debt evidenced
by this Note, and (b) all reasonable costs, expenses, reasonable attorneys' 
fees and reasonable professional fees incurred in (i) any action to collect 
the indebtedness of this Note or to foreclose any security interest
granted to the Holder or (ii) in any litigation or controversy arising from 
or connected with this Note or any other agreement between Maker and Holder.

      2.  Interest.  Accrued interest shall be payable in arrears on the 
first day of each calendar quarter commencing on October 1, 1995.  Any 
installment of interest not paid when due shall also accrue interest at the 
rate set forth herein from the due date thereof until paid.  From the date of 
this Note until the Maturity Date, as hereinafter defined, if any such 
accrued and unpaid interest is not paid when due the amount of the accrued 
and unpaid interest shall be added to the principal balance of this Note. 

      3.  Principal.  The principal amount of this Note shall be paid in a 
single payment, together with all accrued and unpaid interest, on August 21, 
2005 (the "Maturity Date"). 

      4.  Payments.  All payments of principal and interest shall be made in 
immediately available lawful money of the United States.  If any payment due
on, or with respect to, this Note shall fall due on a day other than a 
Business Day (as defined below), then such payment shall be made on the first 
Business Day following the day on which such payment shall have so fallen 
due.  For the purposes of this paragraph, a "Business Day" shall mean a day 
other than a Saturday, a Sunday or a legal holiday in the State of 
Connecticut. 

      5.  Senior Obligation.  Except as noted below, this Note shall be a 
senior obligation of Maker.  During the term of this Note, Maker shall not 
pay any dividends on any class of its common stock or make any other 
distribution or payment of its common stock or make any other distribution 
or payment on account of or in redemption, retirement or purchase of such 
common stock or make payment of any portion of principal or interest on any 
note or debt instrument held by any officer, director or shareholder of Maker
or any affiliate of Maker.  This Note shall be subordinated to any note or 
other debt instrument of Maker payable to a third party unaffiliated with 
Maker or Maker's officers, directors or shareholders ("Third-Party
Debt") only in the event such Third-Party Debt is secured by any assets, 
tangible or intangible, of Maker.  In such event, Maker shall, upon Holder's 
written request, grant Holder a security interest subordinate only
to such Third-Party Debt in the same assets to secure repayment of this 
Note.  Maker shall execute and deliver any and all agreements, documents or 
instruments that Holder may deem necessary or appropriate to perfect such 
subordinate security interest.  In the event such Third-Party Debt is not 
secured by any assets, tangible or intangible of Maker, this Note shall 
rank pari passu with such Third-Party Debt. 

      6.  Events of Default.  Holder shall have the right, at its option, to 
declare the unpaid principal amount of this Note and any accrued interest 
immediately due and payable without presentment, demand, or protest or 
further notice of any kind, all of which are hereby expressly waived by 
Maker, upon the occurrence of any one of the following events (each being an
"Event of Default"):

          (a)  The failure to pay any interest, principal or other sum owing 
     by the Maker to the Holder, whether pursuant to this Note or otherwise, 
     within ten (10) business days of the due date.

          (b)  The breach by Maker of any term, provision, obligation, 
     covenant, representation or warranty arising under (i) this agreement, 
     (ii) any other present or future agreement or instrument between the 
     Maker and Holder or (iii) any present or future agreement or instrument 
     for borrowed money or other financial accommodations with any other 
     person or entity.

          (c)  Maker commences any bankruptcy, reorganization, debt 
     arrangement, or other case or proceeding under the United States 
     Bankruptcy Code or under any similar foreign, federal, state or
     local statute, or any dissolution or liquidation proceeding, or makes a 
     general assignment for the benefit of creditors, or takes any action 
     for the purpose of effecting any of the foregoing.

          (d)  Any bankruptcy, reorganization, debt arrangement, or other 
     case or proceeding under the United States Bankruptcy Code or under 
     similar foreign, federal, state or local statute, or any dissolution 
     or liquidation proceeding, is involuntarily commenced against or in 
     respect of Maker or an order for relief is entered in any such 
     proceeding, and such bankruptcy, reorganization, debt, arrangement, or 
     other case or proceeding or any dissolution or liquidation proceeding 
     is not dismissed within ninety (90) days after the commencement thereof.

          (e)  The appointment, or the filing of a petition seeking the 
     appointment, of a custodian, receiver, trustee, or liquidator for Maker 
     or any of its property, or the taking of possession of any part of the 
     property of Maker at the instance of any governmental authority, and 
     such appointment, filing, or taking of possession is not cured within 
     ninety (90) days after the commencement thereof.

          (f)  Maker becomes insolvent within the meaning of any applicable 
     law, is generally not paying its debts as they become due, or has 
     suspended transaction of its usual business.

          (g)  If Maker shall dissolve or liquidate, or be dissolved or 
     liquidated, or cease to legally exist, or merge into, or consolidate 
     with, any other corporation. 

          (h)  If at any time, the ratio of Maker's current assets (as 
     determined in accordance with generally accepted accounting principles 
     consistently applied) to Maker's current liabilities is less than
     1.25 to 1.0.

          (i)  If at any time, Maker's net worth (as determined in 
     accordance with generally accepted accounting principles consistently 
     applied) is less than $1,250,000.00.

          (j)  Maker transfers or sells all or substantially all of its
     assets, without the prior written consent of the Holder.

          (k)  Maker shall default in the payment or performance of any 
     obligation for borrowed money to the Holder or to any person, firm or 
     corporation (excluding trade creditors in the ordinary course of 
     business).

          (l)  Maker pledges, creates or otherwise suffers the imposition of 
     any liens, security interests, charges or encumbrances upon any of its 
     fixed assets, whether now owned or hereafter acquired, except (i) 
     pledges, security interests, liens, charges or encumbrances existing at 
     the date of this Note, (ii) tax liens or other involuntary liens and 
     encumbrances not yet due and payable, or (iii) mechanics', 
     materialmen's or other involuntary liens and encumbrances which Maker 
     diligently takes actions to remove the same, which lien or encumbrance 
     is removed within ninety (90) days after the imposition thereof.

          (m)  "Change in Control" of the Maker.  A "Change in Control" shall 
     be deemed to have occurred with respect to the Maker if any Person, as 
     defined below, acquires control of the Maker, other than (i) Persons 
     having control at the date of this Note, (ii) the officers and 
     executive officers (as defined under Rules 3b-2 and 3b-7, respectively, 
     under the Securities Exchange Act of 1934, as amended) of the Maker 
     immediately prior to the Change of Control, (iii) the Holder hereof or
     (iv) the holder of a Senior Convertible Promissory Note dated the date 
     hereof, of the Maker in the principal amount of $100,000 .  A Person has 
     control if (w) the Person, directly or indirectly or acting through one 
     or more other Persons, Associates or Affiliates, beneficially owns, 
     controls, or has power to vote 20% or more of the common stock, par 
     value $.75 per share (the "Common Stock"), of Maker; or (x) the Person, 
     directly or indirectly or acting through one or more other Persons,
     Associates or Affiliates, acquires or agrees to acquire all or 
     substantially all of the assets and business of Maker; or (y) the 
     Person, directly or indirectly or acting through one or more other 
     Persons, Associates or Affiliates, controls in any manner the election 
     of a majority of the directors of Maker; or (z) the Board of Directors 
     of Maker determines, in its sole discretion, that a Person, directly or
     indirectly or acting through one or more other Persons, possesses the 
     power to direct or cause the direction of the management and policies of
     the Maker, whether through the ownership of outstanding securities, by 
     contract, or otherwise.  A "Person" shall include a natural person, 
     corporation, trust or other entity.  When two or more Persons act as a 
     partnership, limited partnership, syndicate, or other group for the 
     purpose of acquiring, holding or disposing of Maker's capital stock, 
     such partnership, syndicate, or group shall be considered a Person.  
     Beneficial ownership shall be determined pursuant to the then current 
     provision for Rule 13d-3 under the Securities Exchange Act of 1934 as 
     amended (the "1934 Act").  "Associates" and "Affiliates" shall have the 
     meanings provided in the then current provisions of Rule 12b-2 under 
     the 1934 Act.

      7. Conversion.

          (a)  This Note, or any portion of the principal amount thereof 
     which is $1,500 or an integral multiple of $1,500 (or such lesser 
     amount if the amount of principal outstanding is less than $1,500),
     may be converted at the option of the Holder hereof at any time after 
     the date of this Note set forth above (the "Original Issuance Date") at 
     the principal amount thereof, or of such portion thereof, into fully 
     paid and nonassessable shares of Common Stock of the Maker (rounded to the
     nearest, or if there shall be no nearest, then to the next lower whole 
     share of Common Stock) at the conversion rate of $1.50 per share of 
     Common Stock (the "Conversion Rate").  Upon conversion of this Note,
     or any portion thereof, subject to Section 2 above, the Holder shall be 
     entitled to the amount of any interest accrued and unpaid with respect 
     to this Note through the Conversion Date (as defined in Section 7(c) 
     hereof).  Such interest shall be payable on the Conversion Date.

          (b)  The Conversion Rate shall be subject to the following 
     adjustments:

               (i)  In case the Maker shall declare and pay a dividend in 
     shares of Common Stock, the Conversion Rate in effect immediately prior 
     to the time fixed for the determination of stockholders entitled to 
     such dividend shall be proportionately increased (adjusted to the 
     nearest or if there shall be no nearest, then to the next lower, one-
     hundredth of a share of Common Stock), such adjustment to become 
     effective immediately after the time fixed for such determination.

               (ii) In case the Maker shall subdivide the outstanding shares 
     of Common Stock into a greater number of shares of Common Stock or 
     combine the outstanding shares of Common Stock into a smaller number of 
     shares of Common Stock, the Conversion Rate in effect immediately prior
     to such subdivision or combination, as the case may be, shall be 
     proportionately increased or decreased (adjusted to the nearest, or if 
     there shall be no nearest, then to the next lower, one-hundredth of a 
     share of Common Stock), as the case may require, such increase or 
     decrease to become effective when such subdivision or combination becomes 
     effective. 

             (iii)In case of any reclassification or change of outstanding 
     shares of Common Stock, or in case of any consolidation or merger of 
     the Maker with or into another corporation, or in case of any sale or 
     conveyance to another corporation of all or substantially all of the 
     property of the Maker, the Holder shall have the right thereafter, so 
     long as his conversion right hereunder shall exist, to convert this 
     Note, or any portion thereof, into the kind and amount of shares of
     stock and other securities and property receivable upon such 
     reclassification, change, consolidation, merger, sale or conveyance by
     a holder of the number of shares of Common Stock of the Maker into 
     which this Note, or any portion thereof, might have been converted
     immediately prior to such reclassification, change, consolidation,
     merger, sale or conveyance, and shall have no other conversion rights 
     under these provision; and, effective provisions, if required, shall be
     made in an amendment to this Note or in the Articles or Certificate of
     Incorporation of the resulting, surviving or successor corporation or 
     otherwise, so that the provisions set forth herein for the protection 
     of the conversion rights of the Holder hereof shall hereafter be 
     applicable, as nearly as reasonably may be, to any such other shares of
     stock and other securities and property deliverable upon conversion of 
     this Note, or any portion thereof; and any such resulting, surviving or 
     successor corporation shall expressly assume the obligations to deliver, 
     upon the exercise of the conversion privilege, such shares, securities,
     or property as the Holder hereof shall be entitled to receive pursuant 
     to the provisions hereof, and to make provision for the protection of
     the conversion rights as above provided.  In case securities or 
     property other than shares of Common Stock shall be issuable or 
     deliverable upon conversion as aforesaid, then all references in this
     section shall be deemed to apply so far as appropriate and as nearly as 
     may be, to such other securities or property.  The subdivision or 
     combination of shares of Common stock at any time outstanding into
     a greater or lesser number of shares of Common Stock (whether with or 
     without par value) shall not be deemed to be a reclassification of the
     Common Stock of the Corporation for the purposes of this subsection 
     (iii).
 
          (c)  In order to convert this Note or any portion thereof into 
     shares of Common Stock, the Holder hereof shall give at least thirty 
     (30) days' but not more than ninety (90) days' (or, if a Notice
     of Redemption has been sent or given to the Holder as provided in 
     Section 8(b) hereof, the Holder shall give at least one (1) days' but 
     not more than ninety (90) days') written notice to the Maker at
     the office of the Maker (or such other place as may be designated by 
     the Maker) that the Holder elects to convert the same and shall state 
     in writing therein the name or names in which he wishes the certificate 
     or certificates for shares of Common Stock to be issued and shall 
     surrender this Note, duly endorsed or assigned to the Maker in blank, 
     at said office of the Maker.  The Maker shall, as soon as practicable 
     thereafter, deliver at said office to the Holder, or to his nominee 
     or nominees, a certificate or certificates for the number of full 
     shares of Common Stock to which he shall be entitled.  This Note or any 
     portion thereof shall be deemed to have been converted as of the date 
     of the surrender of this Note for conversion as provided in this 
     Section 7(c) (the "Conversion Date"), and the person or persons 
     entitled to receive the shares of Common Stock issuable upon such
     conversion shall be deemed for all purposes to be the Holder of this 
     Note on such date.

          In case this Note is converted in part only, upon such conversion 
     the Maker shall execute and deliver to the Holder hereof, at the 
     expense of the Maker, a new Note in principal amount equal to
     the unconverted portion of the principal amount of such Note.

          A number of authorized shares of Common Stock sufficient to 
     provide for the conversion of this Note upon the basis of this Section 
     7 shall at all times be reserved for such conversion.

      8.  Redemption.

          (a)  Commencing five years after the Original Issuance Date, this 
     Note may be redeemed, as a whole at any time, or in part from time to 
     time, at the election of the Maker ("Optional Redemption") by 
     resolution of its Board of Directors, out of funds legally available 
     therefor, at a redemption price of one hundred and twenty percent 
     (120%) of the principal amount of this Note, or portion thereof, 
     together with accrued interest to the date of redemption.  

          (b)  Notice of any redemption, specifying the date fixed for said
     redemption and the place where the amount to be paid upon redemption is
     payable (the "Notice of Redemption"), shall be mailed, postage prepaid
     at least ninety (90) days but not more than one hundred and twenty (120)
     days prior to said redemption date to the Holder at his address as the
     same shall appear on the books of the Corporation.  The Notice of 
     Redemption shall include (i) the redemption date; (ii) the principal
     amount; (iii) the redemption price; (iv) the place or places where this 
     Note shall be surrendered for payment of the redemption price; and (v)
     a statement that interest on the principal amount to be redeemed will 
     cease to accrue on such redemption date.   

          If such Notice of Redemption shall have been so mailed, and the 
     Holder shall not have elected to convert this Note or any portion 
     thereof into Common Stock within the time periods set forth in
     Section 7(c) hereof, and if on or before the redemption date specified
     in such notice all funds necessary for such redemption shall have been
     irrevocably deposited in trust, for the account of the Holder (and so 
     as to be and continue to be available therefor), with a bank or trust
     company named in such notice doing business in the State of Connecticut
     and having a combined capital and surplus of at least $100,000,000, 
     thereupon and without awaiting the redemption date, notwithstanding that
     this Note so called for redemption shall not have been surrendered for
     cancellation, this Note, or any portion thereof, so called for 
     redemption shall be deemed to be no longer outstanding and all 
     obligations with respect to this Note or any portion thereof shall 
     be deemed satisfied, the right to receive interest thereon shall cease 
     to accrue, and all rights with respect to this Note or any portion
     thereof so called for redemption shall forthwith upon such deposit in
     trust cease and terminate, except only the right of the Holder thereof
     to receive out of the funds so set aside in trust, the amount
     payable on redemption thereof, but without interest from the date of
     redemption.

          In case the Holder hereof shall not within four (4) years (or 
     any longer period if required by law) after the redemption date claim 
     any amount so deposited in trust for the redemption of such shares, 
     such bank or trust company shall, upon demand and if permitted by 
     applicable law, pay over to the Maker any such unclaimed amount so 
     deposited with it, and shall thereupon be relieved of all 
     responsibility in respect thereof, and thereafter the Holder shall, 
     subject to applicable escheat laws, look only to the Maker for payment
     of the redemption price thereof but without interest.

          (c)  Upon surrender of this Note for redemption, in accordance 
     with the Notice of Redemption, such Note, or portion thereof, shall be
     redeemed by the Maker at the applicable redemption price.  If this Note
     is redeemed in part, a new Note shall be issued by the Maker
     representing  the unredeemed portion, without cost to the Holder of 
     the Note.

     10.  Demand for Payment.  

          (a)  Commencing three years after the Original Issuance Date, the 
     Holder may require the Maker to purchase this Note, as a whole at any 
     time, or in part from time to time, at the election of the Holder (the 
     "Demand for Payment"), out of funds legally available therefor, at a 
     purchase price of one hundred percent (100%) of the principal amount of
     this Note, or portion thereof, together with accrued interest to the 
     date of purchase (the "Purchase Date").

          (b)  In order to make a Demand for Payment, the Holder hereof shall
     give written notice to the Maker at the office of the Maker (or such
     other place as may be designated by the Maker) that (i) the Holder 
     elects to make a Demand for Payment, (ii) the principal amount of the
     Note subject to the Demand for Payment, and (iii) the date of purchase
     (the "Purchase Date") which date shall be at least ninety (90) days but
     not more than one hundred twenty (120) days after such notice is mailed 
     or delivered to the Maker.  The Holder shall surrender this Note, duly
     endorsed to the Maker in blank, at said office of the Maker at least ten
     (10) days prior to the Purchase Date.  On the Purchase Date, the Maker 
     shall deliver to the Holder the purchase price, together with accrued
     interest to the Purchase Date, with respect to the Note or portion 
     thereof subject to the Demand for Payment.  In case the Holder elects 
     to make a Demand for Purchase with respect to only a portion of this 
     Note, the Maker shall also execute and deliver to the Holder hereof on 
     the Purchase Date, at the expense of the Maker, a new Note in principal
     amount equal to the portion of the principal amount not subject to the 
     Demand for Payment.

     11.  Non-Waiver of Rights.  The failure of the Holder to exercise its
option to accelerate the indebtedness of this Note shall not constitute a 
waiver of his right to exercise the same upon the occurrence of any 
continued or subsequent Event of Default.  The failure by the Holder to 
insist upon the strict performance by the Maker of any terms and provisions 
contained herein shall not be deemed to be a waiver of any terms and 
provisions herein, and the Holder shall retain the right thereafter to 
insist upon strict performance by the Maker of any and all terms and 
provisions of this Note or any document securing the repayment of this Note.

     12.  Additional Interest.  The Maker agrees that upon the occurrence 
and during the continuance of an Event of Default, after judgment on behalf 
of the Holder, or on and after the Maturity Date, the indebtedness 
outstanding under this Note shall bear interest at an annual rate of three 
percent (3.0%) above the Prime Rate.

     13.  Maximum Rate of Interest.  Notwithstanding any provision of this 
Note, it is the understanding and agreement of the Maker and the Holder that 
the maximum rate of interest to be paid by the Maker to the Holder shall not 
exceed the highest or the maximum rate of interest permissible to be charged 
under the laws of the State of Connecticut.  Any amount paid in excess of 
such rate shall be considered to have been payments in reduction of principal.

     14.  Choice of Law; Jurisdiction.  To the extent not superseded by 
federal law, this Note shall be governed by and construed in accordance with 
the laws of the State of Connecticut without giving effect to its choice of 
law principles.  The Maker consents to the jurisdiction of the appropriate 
federal or state courts within the State of Connecticut with respect to any 
claims or disputes arising out of the enforcement of this Note.

     15.  Commercial Transaction.  THE MAKER ACKNOWLEDGES THAT THE TRANSACTION
OF WHICH THIS NOTE IS A PART IS A COMMERCIAL TRANSACTION, AND VOLUNTARILY
AND KNOWINGLY WAIVES (A) ALL RIGHTS TO NOTICE AND PRIOR COURT HEARING OR
COURT ORDER PRIOR TO THE ISSUANCE OF ANY PREJUDGMENT REMEDY UNDER
CHAPTER 903a OF THE CONNECTICUT GENERAL STATUTES OR AS OTHERWISE ALLOWED
UNDER ANY STATE OR FEDERAL LAW WITH RESPECT TO ANY PREJUDGMENT REMEDY
WHICH THE HOLDER MAY DESIRE TO USE AND (B) ALL RIGHTS TO REQUEST THAT THE
HOLDER HEREOF POST A BOND, WITH OR WITHOUT SURETY, TO PROTECT SAID MAKER
AGAINST DAMAGES THAT MAY BE CAUSED BY ANY PREJUDGMENT REMEDY SOUGHT OR
OBTAINED BY THE HOLDER HEREOF BY VIRTUE OF ANY DEFAULT OR PROVISION OF THIS
NOTE OR ANY AGREEMENT SECURING THIS NOTE.  THE MAKER ACKNOWLEDGES THAT
IT MAKES THIS WAIVER KNOWINGLY, VOLUNTARILY, WITHOUT DURESS AND ONLY AFTER
CONSIDERATION OF THE RAMIFICATIONS OF THIS WAIVER WITH ITS ATTORNEYS.

     16.  Waiver of Right To Jury Trial.  THE MAKER WAIVES TRIAL BY JURY IN 
ANY COURT IN ANY SUIT, ACTION, PROCEEDING OR ANY MATTER ARISING IN 
CONNECTION WITH OR IN ANY WAY RELATED TO THIS NOTE OR THE FINANCING 
TRANSACTION OF WHICH THIS NOTE IS A PART, OR THE DEFENSE OR ENFORCEMENT OF 
ANY OF THE HOLDER'S RIGHTS AND REMEDIES IN CONNECTION THEREWITH, THE MAKER 
ACKNOWLEDGES THAT IT MAKES THIS WAIVER KNOWINGLY, VOLUNTARILY, WITHOUT 
DURESS AND ONLY AFTER CONSIDERATION OF THE RAMIFICATIONS OF THIS WAIVER WITH
ITS ATTORNEYS.

     17.  Headings.  The descriptive headings of the several sections of 
this Note are inserted for convenience only and shall not be deemed to affect
the meaning or construction of any of the provisions hereof.

     18.  Severability.  If any provision of this Note or application thereof
to any person or circumstance shall to any extent be invalid, the remainder of 
this Note or the application of such provision to persons, entities or 
circumstances other than those as to which it is held invalid, shall not be 
affected thereby and each provision of this Note shall be valid and 
enforceable to the fullest extent permitted by law.

     IN WITNESS WHEREOF, the Maker has caused this Note to be duly executed 
and delivered by the proper and duly authorized officer and agent as of the 
date and year first above written.

                              By  /s/ Norman Silberdick    
                                 Title President




                                                             EXHIBIT 4.2

THE SECURITY EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT 
OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, 
TRANSFERRED, ASSIGNED, PLEDGED OR OTHERWISE DISTRIBUTED FOR VALUE UNLESS (A) 
THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE 
STATE SECURITIES LAWS COVERING SUCH SECURITIES OR (B) COMPUDYNE CORPORATION 
RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES ACCEPTABLE 
TO THE CORPORATION (CONCURRED IN BY COUNSEL FOR THE CORPORATION)
STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT, PLEDGE OR DISTRIBUTION IS EXEMPT 
FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT AND 
SUCH STATE LAWS AND THAT SUCH SALE, TRANSFER, ASSIGNMENT, PLEDGE OR 
DISTRIBUTION WILL NOT CAUSE THE ORIGINAL ISSUANCE OF SUCH SECURITIES BY THE 
CORPORATION TO BE IN VIOLATION OF THE REGISTRATION AND PROSPECTUS DELIVERY 
REQUIREMENTS OF SUCH ACT OR SUCH STATE LAWS.


                     SENIOR CONVERTIBLE PROMISSORY NOTE


$100,000                                                      August 21, 1995

      2.  FOR VALUE RECEIVED, the undersigned COMPUDYNE CORPORATION, a 
Pennsylvania corporation (the "Maker"), promises to pay to the order of ALAN
MARKOWITZ (the "Holder") an individual residing at 26 Barton Hill, East 
Hampton, Connecticut 06424 or at such other place as the Holder
hereof may designate, in lawful money of the United States, the principal 
sum of ONE HUNDRED THOUSAND DOLLARS ($100,000), together with interest on the
unpaid balance of this Note, beginning on the date hereof, before maturity, 
default or judgment, at two percent (2%) above the variable annual rate
equal to the rate published from time to time in The Wall Street Journal 
(Eastern Edition) ("WSJ-EE") as the "Prime Rate" (the base rate on corporate 
loans posted by at least seventy-five percent (75%) of the nation's thirty 
(30) largest banks) (the "Prime Rate").  The interest rate will be adjusted 
upward or downward, as of the date of a change in the Prime Rate; provided, 
however, that at no time shall the interest rate be more than the rate 
permitted by applicable law.  The Prime Rate is not necessarily the lowest 
rate available.  In the event that the "Prime Rate" is no longer published 
from time to time by WSJ-EE, then the term "Prime Rate" shall mean the 
variable rate of interest published or publicly promulgated from time
to time by the WSJ-EE or some other entity generally recognized in the 
financial community as reputable and authoritative, determined by the Holder,
in its sole discretion, most nearly approximate to the base rate on 
corporate loans posted by at least seventy-five percent (75%) of the 
nation's thirty (30) largest banks.  Interest under this Note shall be 
computed daily on the basis of a 360-day year and the actual number of days
elapsed, together with (a) all taxes levied or assessed against the Holder 
of this Note or the debt evidenced by this Note, and (b) all reasonable 
costs, expenses, reasonable attorneys' fees and reasonable professional
fees incurred in (i) any action to collect the indebtedness of this Note or 
to foreclose any security interest granted to the Holder or (ii) in any 
litigation or controversy arising from or connected with this Note or any
other agreement between Maker and Holder.

      2.  Interest.  Accrued interest shall be payable in arrears on the 
first day of each calendar quarter commencing on October 1, 1995.  Any 
installment of interest not paid when due shall also accrue interest
at the rate set forth herein from the due date thereof until paid.  From the 
date of this Note until the Maturity Date, as hereinafter defined, if any 
such accrued and unpaid interest is not paid when due the amount of the 
accrued and unpaid interest shall be added to the principal balance of 
this Note.

      3.  Principal.  The principal amount of this Note shall be paid in a 
single payment, together with all accrued and unpaid interest, on August 21, 
2005 (the "Maturity Date").

      4.  Payments.  All payments of principal and interest shall be made 
in immediately available lawful money of the United States.  If any payment 
due on, or with respect to, this Note shall fall due on a day 
other than a Business Day (as defined below), then such payment shall be 
made on the first Business Day following the day on which such payment shall 
have so fallen due.  For the purposes of this paragraph, a "Business Day" 
shall mean a day other than a Saturday, a Sunday or a legal holiday in the 
State of Connecticut.

      5.  Senior Obligation.  Except as noted below, this Note shall be a 
senior obligation of Maker.  During the term of this Note, Maker shall not 
pay any dividends on any class of its common stock or make any other 
distribution or payment of its common stock or make any other distribution 
or payment on account of or in redemption, retirement or purchase of such 
common stock or make payment of any portion of principal or interest on any 
note or debt instrument held by any officer, director or shareholder of Maker
or any affiliate of Maker.  This Note shall be subordinated to any note or 
other debt instrument of Maker payable to a third party unaffiliated with 
Maker or Maker's officers, directors or shareholders ("Third-Party Debt") 
only in the event such Third-Party Debt is secured by any assets, tangible 
or intangible, of Maker.  In such event, Maker shall, upon Holder's written 
request, grant Holder a security interest subordinate only
to such Third-Party Debt in the same assets to secure repayment of this Note. 
Maker shall execute and deliver any and all agreements, documents or 
instruments that Holder may deem necessary or appropriate to perfect such 
subordinate security interest.  In the event such Third-Party Debt is not 
secured by any assets, tangible or intangible of Maker, this Note shall 
rank pari passu with such Third-Party Debt. 

      6.  Events of Default.  Holder shall have the right, at its option, to
declare the unpaid principal amount of this Note and any accrued interest 
immediately due and payable without presentment, demand, or protest or 
further notice of any kind, all of which are hereby expressly waived by 
Maker, upon the occurrence of any one of the following events (each being an 
"Event of Default"): 

          (a)  The failure to pay any interest, principal or other sum owing 
     by the Maker to the Holder, whether pursuant to this Note or otherwise, 
     within ten (10) business days of the due date.

          (b)  The breach by Maker of any term, provision, obligation, 
     covenant, representation or warranty arising under (i) this agreement, 
     (ii) any other present or future agreement or instrument between the 
     Maker and Holder or (iii) any present or future agreement or instrument 
     for borrowed money or other financial accommodations with any other 
     person or entity.

          (c)  Maker commences any bankruptcy, reorganization, debt 
     arrangement, or other case or proceeding under the United States 
     Bankruptcy Code or under any similar foreign, federal, state or
     local statute, or any dissolution or liquidation proceeding, or makes 
     a general assignment for the benefit of creditors, or takes any action 
     for the purpose of effecting any of the foregoing.

          (d)  Any bankruptcy, reorganization, debt arrangement, or other 
     case or proceeding under the United States Bankruptcy Code or under 
     similar foreign, federal, state or local statute, or any dissolution or 
     liquidation proceeding, is involuntarily commenced against or in 
     respect of Maker or an order for relief is entered in any such 
     proceeding, and such bankruptcy, reorganization, debt, arrangement, or 
     other case or proceeding or any dissolution or liquidation proceeding 
     is not dismissed within ninety (90) days after the commencement thereof.

          (e)  The appointment, or the filing of a petition seeking the 
     appointment, of a custodian, receiver, trustee, or liquidator for Maker 
     or any of its property, or the taking of possession of any part of the 
     property of Maker at the instance of any governmental authority, and 
     such appointment, filing, or taking of possession is not cured within 
     ninety (90) days after the commencement thereof.

          (f)  Maker becomes insolvent within the meaning of any applicable 
     law, is generally not paying its debts as they become due, or has 
     suspended transaction of its usual business.

          (g)  If Maker shall dissolve or liquidate, or be dissolved or 
     liquidated, or cease to legally exist, or merge into, or consolidate 
     with, any other corporation.

          (h)  If at any time, the ratio of Maker's current assets (as 
     determined in accordance with generally accepted accounting principles 
     consistently applied) to Maker's current liabilities is less than
     1.25 to 1.0.

          (i)  If at any time, Maker's net worth (as determined in 
     accordance with generally accepted accounting principles consistently 
     applied) is less than $1,250,000.00.

          (j)  Maker transfers or sells all or substantially all of its 
     assets, without the prior written consent of the Holder.

          (k)  Maker shall default in the payment or performance of any 
     obligation for borrowed money to the Holder or to any person, firm or 
     corporation (excluding trade creditors in the ordinary course of 
     business).

          (l)  Maker pledges, creates or otherwise suffers the imposition of 
     any liens, security interests, charges or encumbrances upon any of its 
     fixed assets, whether now owned or hereafter acquired, except (i) 
     pledges, security interests, liens, charges or encumbrances existing at 
     the date of this Note, (ii) tax liens or other involuntary liens and 
     encumbrances not yet due and payable, or (iii) mechanics', materialmen's
     or other involuntary liens and encumbrances which Maker diligently takes
     actions to remove the same, which lien or encumbrance is removed within 
     ninety (90) days after the imposition thereof.

          (m)  "Change in Control" of the Maker.  A "Change in Control" shall
     be deemed to have occurred with respect to the Maker if any Person, as 
     defined below, acquires control of the Maker, other than (i) Persons 
     having control at the date of this Note, (ii) the officers and 
     executive officers (as defined under Rules 3b-2 and 3b-7, respectively, 
     under the Securities Exchange Act of 1934, as amended) of the Maker 
     immediately prior to the Change of Control, (iii) the Holder hereof or 
     (iv) the holder of a Senior Convertible Promissory Note dated the date
     hereof, of the Maker in the principal amount of $300,000.  A Person has 
     control if (w) the Person, directly or indirectly or acting through one 
     or more other Persons, Associates or Affiliates, beneficially owns, 
     controls, or has power to vote 20% or more of the common stock, par 
     value $.75 per share (the "Common Stock"), of Maker; or (x) the Person, 
     directly or indirectly or acting through one or more other Persons, 
     Associates or Affiliates, acquires or agrees to acquire all or 
     substantially all of the assets and business of Maker; or (y) the 
     Person, directly or indirectly or acting through one or more other 
     Persons, Associates or Affiliates, controls in any manner the election 
     of a majority of the directors of Maker; or (z) the Board of Directors 
     of Maker determines, in its sole discretion, that a Person, directly or 
     indirectly or acting through one or more other Persons, possesses the 
     power to direct or cause the direction of the management and policies 
     of the Maker, whether through the ownership of outstanding securities, 
     by contract, or otherwise.  A "Person" shall include a natural person, 
     corporation, trust or other entity.  When two or more Persons act as a 
     partnership, limited partnership, syndicate, or other group for the 
     purpose of acquiring, holding or disposing of Maker's capital stock, such 
     partnership, syndicate, or group shall be considered a Person.  
     Beneficial ownership shall be determined pursuant to the then current 
     provision for Rule 13d-3 under the Securities Exchange Act of 1934 as 
     amended (the "1934 Act").  "Associates" and "Affiliates" shall have the 
     meanings provided in the then current provisions of Rule 12b-2 under 
     the 1934 Act.

     7. Conversion.

          (a)  This Note, or any portion of the principal amount thereof 
     which is $1,500 or an integral multiple of $1,500 (or such lesser 
     amount if the amount of principal outstanding is less than $1,500),
     may be converted at the option of the Holder hereof at any time after 
     the date of this Note set forth above (the "Original Issuance Date") at 
     the principal amount thereof, or of such portion thereof, into
     fully paid and nonassessable shares of Common Stock of the Maker 
     (rounded to the nearest, or if there shall be no nearest, then to the 
     next lower whole share of Common Stock) at the conversion
     rate of $1.50 per share of Common Stock (the "Conversion Rate").  Upon 
     conversion of this Note, or any portion thereof, subject to Section 2 
     above, the Holder shall be entitled to the amount of any interest 
     accrued and unpaid with respect to this Note through the Conversion Date 
     (as defined in Section 7(c) hereof).  Such interest shall be payable on 
     the Conversion Date.

          (b)  The Conversion Rate shall be subject to the following 
     adjustments:

               (i)  In case the Maker shall declare and pay a dividend in 
     shares of Common Stock, the Conversion Rate in effect immediately prior
     to the time fixed for the determination of stockholders entitled to 
     such dividend shall be proportionately increased (adjusted to the 
     nearest or if there shall be no nearest, then to the next lower, one-
     hundredth of a share of Common Stock), such adjustment to become 
     effective immediately after the time fixed for such determination.

               (ii) In case the Maker shall subdivide the outstanding shares 
     of Common Stock into a greater number of shares of Common Stock or 
     combine the outstanding shares of Common Stock into a smaller number of 
     shares of Common Stock, the Conversion Rate in effect immediately prior
     to such subdivision or combination, as the case may be, shall be 
     proportionately increased or decreased (adjusted to the nearest, or if 
     there shall be no nearest, then to the next lower, one-hundredth of a 
     share of Common Stock), as the case may require, such increase or 
     decrease to become effective when such subdivision or combination 
     becomes effective. 

             (iii) In case of any reclassification or change of outstanding 
     shares of Common Stock, or in case of any consolidation or merger of 
     the Maker with or into another corporation, or in case of any
     sale or conveyance to another corporation of all or substantially all of
     the property of the Maker, the Holder shall have the right thereafter, 
     so long as his conversion right hereunder shall exist, to convert
     this Note, or any portion thereof, into the kind and amount of shares of
     stock and other securities and property receivable upon such 
     reclassification, change, consolidation, merger, sale or conveyance by
     a holder of the number of shares of Common Stock of the Maker into which 
     this Note, or any portion thereof, might have been converted 
     immediately prior to such reclassification, change, consolidation,
     merger, sale or conveyance, and shall have no other conversion rights 
     under these provision; and, effective provisions, if required, shall be 
     made in an amendment to this Note or in the Articles or Certificate of 
     Incorporation of the resulting, surviving or successor corporation or 
     otherwise, so that the provisions set forth herein for the protection 
     of the conversion rights of the Holder hereof shall hereafter be 
     applicable, as nearly as reasonably may be, to any such other shares of 
     stock and other securities and property deliverable upon conversion of 
     this Note, or any portion thereof; and any such resulting, surviving or 
     successor corporation shall expressly assume the obligations to deliver,
     upon the exercise of the conversion privilege, such shares, securities, 
     or property as the Holder hereof shall be entitled to receive pursuant 
     to the provisions hereof, and to make provision for the protection of 
     the conversion rights as above provided.  In case securities or 
     property other than shares of Common Stock shall be issuable or 
     deliverable upon conversion as aforesaid, then all references in this 
     section shall be deemed to apply so far as appropriate and as nearly as 
     may be, to such other securities or property.  The subdivision or 
     combination of shares of Common stock at any time outstanding into a 
     greater or lesser number of shares of Common Stock (whether with or 
     without par value) shall not be deemed to be a reclassification of the 
     Common Stock of the Corporation for the purposes of this subsection 
     (iii).
 
          (c)  In order to convert this Note or any portion thereof into 
     shares of Common Stock, the Holder hereof shall give at least thirty 
     (30) days' but not more than ninety (90) days' (or, if a Notice
     of Redemption has been sent or given to the Holder as provided in 
     Section 8(b) hereof, the Holder shall give at least one (1) days' but 
     not more than ninety (90) days') written notice to the Maker at
     the office of the Maker (or such other place as may be designated by 
     the Maker) that the Holder elects to convert the same and shall state 
     in writing therein the name or names in which he wishes the certificate 
     or certificates for shares of Common Stock to be issued and shall 
     surrender this Note, duly endorsed or assigned to the Maker in blank, 
     at said office of the Maker.  The Maker shall, as soon as practicable 
     thereafter, deliver at said office to the Holder, or to his nominee or 
     nominees, a certificate or certificates for the number of full shares 
     of Common Stock to which he shall be entitled. This Note or any portion 
     thereof shall be deemed to have been converted as of the date of the
     surrender of this Note for conversion as provided in this Section 7(c) 
     (the "Conversion Date"), and the person or persons entitled to receive 
     the shares of Common Stock issuable upon such conversion shall be 
     deemed for all purposes to be the Holder of this Note on such date.

          In case this Note is converted in part only, upon such conversion 
     the Maker shall execute and deliver to the Holder hereof, at the expense
     of the Maker, a new Note in principal amount equal to the unconverted 
     portion of the principal amount of such Note.

          A number of authorized shares of Common Stock sufficient to provide 
     for the conversion of this Note upon the basis of this Section 7 shall 
     at all times be reserved for such conversion.

      8.  Redemption.

          (a)  Commencing five years after the Original Issuance Date, this 
     Note may be redeemed, as a whole at any time, or in part from time to 
     time, at the election of the Maker ("Optional Redemption") by 
     resolution of its Board of Directors, out of funds legally available 
     therefor, at a redemption price of one hundred and twenty percent 
     (120%) of the principal amount of this Note, or portion thereof, 
     together with accrued interest to the date of redemption.  

          (b)  Notice of any redemption, specifying the date fixed for said 
     redemption and the place where the amount to be paid upon redemption is 
     payable (the "Notice of Redemption"), shall be mailed, postage prepaid 
     at least ninety (90) days but not more than one hundred and twenty (120)
     days prior to said redemption date to the Holder at his address as the
     same shall appear on the books of the Corporation.  The Notice of 
     Redemption shall include (i) the redemption date; (ii) the principal
     amount; (iii) the redemption price; (iv) the place or places where this
     Note shall be surrendered for payment of the redemption price; and (v) 
     a statement that interest on the principal amount to be redeemed will 
     cease to accrue on such redemption date.  

          If such Notice of Redemption shall have been so mailed, and the 
     Holder shall not have elected to convert this Note or any portion 
     thereof into Common Stock within the time periods set forth in Section 
     7(c) hereof, and if on or before the redemption date specified in such 
     notice all funds necessary for such redemption shall have been 
     irrevocably deposited in trust, for the account of the Holder (and so as
     to be and continue to be available therefor), with a bank or trust 
     company named in such notice doing business in the State of Connecticut 
     and having a combined capital and surplus of at least $100,000,000, 
     thereupon and without awaiting the redemption date, notwithstanding that
     this Note so called for redemption shall not have been surrendered for 
     cancellation, this Note, or any portion thereof, so called for 
     redemption shall be deemed to be no longer outstanding and all
     obligations with respect to this Note or any portion thereof shall be
     deemed satisfied, the right to receive interest thereon shall cease to 
     accrue, and all rights with respect to this Note or any portion
     thereof so called for redemption shall forthwith upon such deposit in
     trust cease and terminate, except only the right of the Holder thereof 
     to receive out of the funds so set aside in trust, the amount
     payable on redemption thereof, but without interest from the date of 
     redemption.

          In case the Holder hereof shall not within four (4) years (or any 
     longer period if required by law) after the redemption date claim any 
     amount so deposited in trust for the redemption of such shares, such 
     bank or trust company shall, upon demand and if permitted by applicable 
     law, pay over to the Maker any such unclaimed amount so deposited with 
     it, and shall thereupon be relieved of all responsibility in respect 
     thereof, and thereafter the Holder shall, subject to applicable escheat 
     laws, look only to the Maker for payment of the redemption price thereof 
     but without interest.

          (c)  Upon surrender of this Note for redemption, in accordance with 
     the Notice of Redemption, such Note, or portion thereof, shall be 
     redeemed by the Maker at the applicable redemption price.  If this Note 
     is redeemed in part, a new Note shall be issued by the Maker 
     representing the unredeemed portion, without cost to the Holder of the
     Note.

     10.  Demand for Payment.  

          (a)  Commencing three years after the Original Issuance Date, the 
     Holder may require the Maker to purchase this Note, as a whole at any 
     time, or in part from time to time, at the election of the Holder (the 
     "Demand for Payment"), out of funds legally available therefor, at a 
     purchase price of one hundred percent (100%) of the principal amount of 
     this Note, or portion thereof, together with accrued interest to the 
     date of purchase (the "Purchase Date").

          (b)  In order to make a Demand for Payment, the Holder hereof 
     shall give written notice to the Maker at the office of the Maker (or 
     such other place as may be designated by the Maker) that (i) the Holder 
     elects to make a Demand for Payment, (ii) the principal amount of the 
     Note subject to the Demand for Payment, and (iii) the date of purchase 
     (the "Purchase Date") which date shall be at least ninety (90) days but 
     not more than one hundred twenty (120) days after such notice is 
     mailed or delivered to the Maker.  The Holder shall surrender this 
     Note, duly endorsed to the Maker in blank, at said office of the Maker 
     at least ten (10) days prior to the Purchase Date.  On the Purchase 
     Date, the Maker shall deliver to the Holder the purchase price, 
     together with accrued interest to the Purchase Date, with respect to 
     the Note or portion thereof subject to the Demand for Payment.  In case 
     the Holder elects to make a Demand for Purchase with respect to only a 
     portion of this Note, the Maker shall also execute and deliver to the 
     Holder hereof on the Purchase Date, at the expense of the Maker, a new 
     Note in principal amount equal to the portion of the principal
     amount not subject to the Demand for Payment.

     11.  Non-Waiver of Rights.  The failure of the Holder to exercise its 
option to accelerate the indebtedness of this Note shall not constitute a 
waiver of his right to exercise the same upon the occurrence of any 
continued or subsequent Event of Default.  The failure by the Holder to 
insist upon the strict performance by the Maker of any terms and provisions 
contained herein shall not be deemed to be a waiver of any terms and 
provisions herein, and the Holder shall retain the right thereafter to 
insist upon strict performance by the Maker of any and all terms and 
provisions of this Note or any document securing the repayment of this Note.

     12.  Additional Interest.  The Maker agrees that upon the occurrence and
during the continuance of an Event of Default, after judgment on behalf of the 
Holder, or on and after the Maturity Date, the indebtedness outstanding 
under this Note shall bear interest at an annual rate of three percent 
(3.0%) above the Prime Rate.

     13.  Maximum Rate of Interest.  Notwithstanding any provision of this 
Note, it is the understanding and agreement of the Maker and the Holder that 
the maximum rate of interest to be paid by the Maker to the Holder shall not 
exceed the highest or the maximum rate of interest permissible to be charged 
under the laws of the State of Connecticut.  Any amount paid in excess of 
such rate shall be considered to have been payments in reduction of principal.

     14.  Choice of Law; Jurisdiction.  To the extent not superseded by 
federal law, this Note shall be governed by and construed in accordance with 
the laws of the State of Connecticut without giving effect to its choice of 
law principles.  The Maker consents to the jurisdiction of the appropriate 
federal or state courts within the State of Connecticut with respect to any 
claims or disputes arising out of the enforcement of this Note.

     15.  Commercial Transaction.  THE MAKER ACKNOWLEDGES THAT THE 
TRANSACTION OF WHICH THIS NOTE IS A PART IS A COMMERCIAL TRANSACTION, AND 
VOLUNTARILY AND KNOWINGLY WAIVES (A) ALL RIGHTS TO NOTICE AND PRIOR COURT 
HEARING OR COURT ORDER PRIOR TO THE ISSUANCE OF ANY PREJUDGMENT REMEDY UNDER
CHAPTER 903a OF THE CONNECTICUT GENERAL STATUTES OR AS OTHERWISE ALLOWED
UNDER ANY STATE OR FEDERAL LAW WITH RESPECT TO ANY PREJUDGMENT REMEDY
WHICH THE HOLDER MAY DESIRE TO USE AND (B) ALL RIGHTS TO REQUEST THAT THE
HOLDER HEREOF POST A BOND, WITH OR WITHOUT SURETY, TO PROTECT SAID MAKER
AGAINST DAMAGES THAT MAY BE CAUSED BY ANY PREJUDGMENT REMEDY SOUGHT OR
OBTAINED BY THE HOLDER HEREOF BY VIRTUE OF ANY DEFAULT OR PROVISION OF THIS
NOTE OR ANY AGREEMENT SECURING THIS NOTE.  THE MAKER ACKNOWLEDGES THAT
IT MAKES THIS WAIVER KNOWINGLY, VOLUNTARILY, WITHOUT DURESS AND ONLY AFTER
CONSIDERATION OF THE RAMIFICATIONS OF THIS WAIVER WITH ITS ATTORNEYS.

     16.  Waiver of Right To Jury Trial.  THE MAKER WAIVES TRIAL BY JURY IN 
ANY COURT IN ANY SUIT, ACTION, PROCEEDING OR ANY MATTER ARISING IN 
CONNECTION WITH OR IN ANY WAY RELATED TO THIS NOTE OR THE FINANCING 
TRANSACTION OF WHICH THIS NOTE IS A PART, OR THE DEFENSE OR ENFORCEMENT OF 
ANY OF THE HOLDER'S RIGHTS AND REMEDIES IN CONNECTION THEREWITH, THE MAKER 
ACKNOWLEDGES THAT IT MAKES THIS WAIVER KNOWINGLY, VOLUNTARILY, WITHOUT 
DURESS AND ONLY AFTER CONSIDERATION OF THE RAMIFICATIONS OF THIS WAIVER WITH 
ITS ATTORNEYS.

     17.  Headings.  The descriptive headings of the several sections of 
this Note are inserted for convenience only and shall not be deemed to 
affect the meaning or construction of any of the provisions hereof.

     18.  Severability.  If any provision of this Note or application 
thereof to any person or circumstance shall to any extent be invalid, the 
remainder of this Note or the application of such provision to persons,
entities or circumstances other than those as to which it is held invalid, 
shall not be affected thereby and each provision of this Note shall be valid 
and enforceable to the fullest extent permitted by law.

     IN WITNESS WHEREOF, the Maker has caused this Note to be duly executed 
and delivered by the proper and duly authorized officer and agent as of the 
date and year first above written.

     duly organized, validly existing and in good standing under the laws of
     the State of Connecticut, with corporate power and authority to own,
     operate and lease its properties and carry on its business as now
     conducted, and is duly qualified to do business and is in good standing

     qualify would have a material adverse effect on its business and
     operations taken as a whole.

2.2  Capitalization.  The authorized capital stock consists of 20,000 shares
     of MASI Common Stock, par value $0.10 per share, of which 1,664 shares are

     position of the Company at the dates, and the results of operations of the

     sheet of the Company as of June 30, 1995 and the related operating
     statement for the six month period ended June 30, 1995 previously
     furnished to Buyer present fairly the financial position of the Company
     at the dates, and the results of operations of the Company for the

     charges of every kind and character other than:  (i) the lien of current
     state and local property taxes not in default, (ii) the encumbrances,
     liens and charges set forth in the balance sheet as of the Financials Date
     or in Schedule 2.6, and (iii) such other minor liens, encumbrances,
     easements, rights of way, restrictions, exceptions, reservations,
     limitations, burdens and other imperfections as do not materially detract
     from the value of such real property or impair its use for the purposes
     for which it is now employed, or materially affect the validity of the
     title thereto, and all leases or subleases under which it claims or holds
     leasehold interests (all of which are listed on Schedule 2.6) are
     currently in effect and there is not, under any of such instruments, any
     existing default or event of default which with notice or lapse of time,
     or both, would constitute a default.

2.7  Personal Property.  The Company has good and marketable title to all
     personal tangible and intangible property reflected in the balance sheet
     as of the Financials Date, except for such changes in such personal
     tangible and intangible property made since the Financials Date in the
     ordinary course of business, free and clear of all encumbrances, liens or
     charges of any kind or character other than encumbrances, liens or charges
     (i) incurred in the ordinary course of the business of the Company or (ii)
     set forth in the balance sheet as of the Financials Date.

     and tradenames necessary to conduct the business now being conducted by

2.10 Material Contracts.  Except for agreements, plans or obligations referred
     to in Section 2.11 and leases referred to in Section 2.6, Schedule 2.10
     contains a complete list identifying all outstanding contracts, purchase
     orders, agreements, leases (whether as landlord or tenant), indentures,

     individual contracts, purchase orders, agreements or leases of personal
     property which involve payments by or to the Company of less than $50,000. 
     Except for immaterial defaults in contracts and agreements with customers
     and suppliers which are consistent with past practice, in the ordinary
     course of business and which are known to, and not objected to by, the
     other party thereto, no event has occurred which with or without notice,

     of any default by any other party thereto.

     plans.  Neither the Company, nor, to the knowledge of the Company and each
     Seller, any other party to any such agreement or plan, is in breach
     thereof or default thereunder, and no event has occurred that with the
     passage of time or the giving of notice, or both, would constitute such
     a breach or default.

2.12 Taxes.  The Company has filed all tax and similar returns and has paid or
     provided for the payment of all taxes and assessments due.  The Company
     has no knowledge of any claims for taxes which might become a lien upon

     contemplated hereby.  The execution and delivery of this Agreement and the
     consummation of the transactions contemplated hereby have been duly and
     validly authorized and approved by the Board of Directors of the Company
     and its shareholders, and no other corporate proceedings on the part of
     the Company are necessary to authorize this Agreement or to consummate the
     transactions contemplated hereby.  This Agreement has been duly and
     validly executed and delivered by the Company and each Seller and
     constitutes a valid and binding agreement of the Company and each Seller. 
     No filing with, and no permit, authorization, consent or approval of any
     public body or authority, the absence of which would, either individually
     or in the aggregate, have a material adverse effect on the business or
     financial condition of the Company, is necessary for the consummation by
     the Company and the Sellers of the transactions contemplated by this
     Agreement.

2.15 No Breach or Default.  The execution and delivery of this Agreement and
     the consummation of the transactions contemplated hereby will not (i)
     violate any provision of the Certificate of Incorporation or By-laws of
     the Company, (ii) violate any statute, rule, regulation, order or decree
     of any public body or authority of the United States or any state or
     municipality thereof by which Seller or the Company or any of their
     respective properties is bound, which violation or violations either
     individually or in the aggregate would have a material adverse affect on
     the business or financial condition of the Company, or (iii) result in a
     violation or breach of, or constitute (with or without due notice or lapse
     of time or both) a default under, any license, franchise, permit,
     indenture, agreement, shareholders' agreement, voting trust agreement or
     other instrument to which any of the Sellers or the Company is a party,
     or by which any of them or any of their respective properties is bound
     which violation, breach or default either individually or in the aggregate
     would have a material adverse effect on the business or financial
     condition of the Company.

2.16 Finders and Investment Bankers.  Neither Seller, the Company nor any of
     its officers, directors or agents has employed any broker or finder or
     incurred any liability that is or would be an obligation of the Company
     or the Buyer for any brokerage fees, commissions or finders' fees in
     connection with the transactions contemplated herein.

2.17 Investment.  Each Seller is acquiring the Preference Stock and the Notes
     referred to in Section 5.5 hereof (the Preference Stock and the Notes are
     collectively referred to herein as the "Securities"), and Roenigk is
     acquiring the CompuDyne Options referred to in Section 6.7 hereof and the
     Corcap Options referred to in Section 6.8 hereof (the CompuDyne Options
     and the Corcap Options are collectively referred to herein as the
     "Options"), for his own account as principal and not with a view to, or
     for, distribution or fractionalization thereof, in whole or in part, and
     no other person has a direct or indirect beneficial interest in such
     Securities or Options.

2.18 No Distributive Intent.  Neither Seller will sell or otherwise transfer
     any Securities or Options without registration under the Securities Act
     of 1933, as amended (the "Act"), and under applicable state securities or
     "blue sky" laws, or pursuant to an exemption therefrom.  Each Seller fully
     understands and agrees that he must bear the economic risk of the
     Securities and Options for an indefinite period of time because, among
     other reasons, neither the Securities nor the Options have been registered
     under the Act or under the securities laws of any state and, therefore,
     they cannot be resold, pledged, assigned or otherwise disposed of unless
     they are subsequently registered under the Act and under the applicable
     securities laws of such states or an exemption from such registration is
     available.  Each certificate for the Securities and Options will be
     imprinted with a legend in substantially the following form:

          The security evidenced hereby has not been registered under
          the Securities Act of 1933, as amended, or any state
          securities laws and may not be sold, transferred, assigned,
          pledged or otherwise distributed for value unless (a) there
          is an effective registration statement under such act and
          applicable state securities laws covering such securities
          or (b) the Corporation receives an opinion of counsel for
          the holder of these securities acceptable to the
          Corporation (concurred in by counsel for the Corporation)
          stating that such sale, transfer, assignment, pledge or
          distribution is exempt from the registration and prospectus
          delivery requirements of such Act and such state laws and
          that such sale, transfer, assignment, pledge or
          distribution will not cause the original issuance of such
          securities by the Corporation to be in violation of the
          registration and prospectus delivery requirements of such
          Act or such state laws.

2.19 Information.  Each Seller has received and reviewed a copy of the Buyer's
     Annual Reports filed on Form 10-K, Quarterly Reports filed on Form 10-Q
     and Current Reports filed on Form 8-K for the past two years.  Each Seller
     has been granted the opportunity to ask questions of, and receive answers
     from, officers and employees of the Buyer and its subsidiaries concerning
     the Buyer and has been granted full access to the books and records of the
     Buyer, as Sellers deem necessary to make an informed investment decision.

2.20 Accredited Investor.  Each Seller has read the text of Rule 501(a)(1)-(8)
     of Regulation D under the Act, and confirms that he is an "accredited
     investor" as described thereby.

2.21 Experience.  Each Seller has such knowledge and experience in financial
     and business matters that he is capable of evaluating the merits and risks
     of the purchase of the Securities and Options.


                                 ARTICLE III

     Buyer represents and warrants to the Company and each Seller as follows:

3.1  Organization and Standing of the Buyer.  Buyer is a corporation duly

3.3  Subsidiaries.  Except as disclosed in Schedule 3.3, the Buyer does not own

     power and authority to own, operate and lease its properties and carry on
     its business as now conducted, and is duly qualified to do business and

     respective business and operations taken as a whole.  Buyer owns all of
     the issued and outstanding stock of each such subsidiary.

3.4  Financial Statements.  The balance sheets of the Buyer as of December 31,
     1994 and 1993 and the related statements of income, changes in financial
     position and stockholders' equity for the years ended December 31, 1994
     and 1993 previously furnished to Buyer, present fairly the financial
     position of the Buyer at the dates, and the results of operations of the
     Buyer for the periods, stated therein in conformity with generally
     accepted accounting principles applied on a consistent basis.  The balance
     sheet of Buyer as of June 30, 1995 and the related statement of income for
     the six-month period ended June 30, 1995 previously furnished to the
     Company and the Sellers present fairly the financial position of Buyer at
     the dates, and the results of operations of Buyer for the periods, stated

     leasehold interests in all of the real property which it occupies or uses
     in its operations, including the plants, buildings and improvements

     property taxes not in default, (ii) the encumbrances, liens and charges
     set forth in the balance sheet as of the Financials Date or in Schedule

     and suppliers which are consistent with past practice, in the ordinary
     course of business and which are known to, and not objected to by, the

     individually or in the aggregate would have a material adverse effect on
     the business or financial condition of Buyer.

     directors or agents has employed any broker or finder or incurred any
     liability that is or would be an obligation of the Company or the Buyer

          (b)  Each party hereto will hold and will cause its representatives,

                                 ARTICLE VII

                             REGISTRATION RIGHTS

7.1  Piggyback Registration Rights.  

          (a)  Right to Piggyback.  Whenever the Buyer proposes to register any
     shares of CompuDyne Common Stock (or securities convertible into or
     exchangeable or exercisable for CompuDyne Common Stock) under the
     Securities Act (a "Proposed Registration"), and the registration form to
     be used may be used for the registration of the Registrable Securities as
     defined in Section 7.7 below (a "Piggyback Registration"), the Buyer will
     give prompt written notice to each holder of record of the Preference
     Stock and the Notes (the "Securityholders") at his address as the same
     shall appear on the books of the Buyer of the Buyer's intention to effect
     such a registration.  Such notice will specify among other things the
     proposed offering price, the kind and number of securities proposed to be
     registered, the distribution arrangements and  such other information that
     at the time would be appropriate to include in such notice, and will,
     subject to paragraph 7.1(b) below, offer to include in such Piggyback
     Registration all Registrable Securities with respect to which the Buyer
     has received written requests for inclusion therein within 15 business
     days after receipt of the Buyer's notice.  Except as may otherwise be
     provided in this Agreement, Registrable Securities with respect to which
     such request for registration has been received within such 15-day period
     will be registered by the Buyer and offered to the public pursuant to this
     Article VII on the same terms and subject to the same conditions
     applicable to the registration in a Proposed Registration of such shares
     of CompuDyne Common Stock (or securities convertible into or exchangeable
     or exercisable for CompuDyne Common Stock) to be sold by the Buyer or by
     the person selling under such Proposed Registration.

          (b)  Priority on Piggyback Registrations.  If the managing
     underwriter or underwriters, if any, advise the holders of Registrable
     Securities in writing that in its or their opinion, or, in the case of a
     Piggyback Registration not being underwritten, the Buyer shall reasonably
     determine (and notify the holders of Registrable Securities of such
     determination) after consultation with an investment banker or advisor of
     nationally recognized standing, that the number or kind of securities
     proposed to be sold in such registration (including Registrable Securities
     to be included in paragraph 7.1(a) above) will adversely affect the
     success of such offering, the Buyer will include in such registration the
     number of securities, if any, which, in the opinion of such underwriter
     or underwriters, or the Buyer, as the case may be, can be sold as follows: 
     (i) first, the shares of CompuDyne Common Stock the Buyer proposes to
     sell, (ii) second, the Registrable Securities requested to be included in
     such registration by the Securityholders, and (iii) third, other shares
     of CompuDyne Common Stock held by persons other than the Securityholders
     requested to be included in such registration, provided, however, that any
     Piggyback Registration must include a minimum number of shares of
     Registrable Securities equal to the product obtained by multiplying (i)
     the number of shares being registered in the Proposed Registration by (ii)
     a fraction, the numerator of which is the number of Registrable Securities
     and the denominator of which is the number of shares of Common Stock of
     the Buyer on a fully diluted basis.

7.2  Demand Registration Rights.

          (a)  Right to Demand.  At any time after 24 months following the
     Closing Date, at least 60% of the Securityholders may collectively make
     a written request to the Buyer for registration with the Securities and
     Exchange Commission under and in accordance with the provisions of the Act
     of all or part of their Registrable Securities (a "Demand Registration"). 
     Within 10 days after receipt of such request, the Buyer will serve written
     notice (the "Buyer's Notice") of such registration request to all other
     Securityholders notifying such holders of the Demand Registration and
     stating that any Securityholder who wishes to be included in such
     registration shall notify the Buyer within 15 days of the date of the
     Buyer's Notice (the "Inclusion Deadline").  Any Securityholder who does
     not so notify the Buyer by the Inclusion Deadline forfeits his right to
     have his Registrable Securities included in the registration.  All
     requests of the Securityholders pursuant to this Section shall specify the
     aggregate number of Registrable Securities to be registered and shall also
     specify the intended methods of disposition thereof.

          Within 15 days after the Inclusion Deadline, the Buyer will advise
     the Securityholders who made the Demand Registration and any other
     Securityholder who notified the Buyer of his desire to be included in the
     registration by the Inclusion Deadline (the "Selling Securityholders")
     whether, in the reasonable judgment of the Board of Directors of the Buyer
     (after consultation with an investment banker or advisor of nationally
     recognized standing), (i) the Company has sufficient working capital,
     together with projected cash flow (x) to pay for the costs associated with
     the registration and offering of the Registrable Securities to be
     registered, (y) to satisfy its current liabilities and liabilities
     expected to arise over the next 18 months as such liabilities become due,
     and (z) to provide a sufficient reserve for extraordinary expenses
     reasonably anticipated, and (ii) there is a reasonable likelihood of
     completing a successful public offering of such securities within the next
     12 months taking into account the financial condition of the Buyer, the
     market for securities existing at the time and in the foreseeable future,
     and the amount of Registrable Securities to be registered pursuant to this
     Section 7.2(a).

          If the Board of Directors of the Buyer, in its reasonable judgment,
     determines to proceed with the registration, the Buyer shall include in
     such registration all Registrable Securities of the Selling
     Securityholders as to which the Buyer has received written requests for
     inclusion and shall promptly proceed to register such securities.  The
     Securityholders shall have the right to make two Demand Registrations
     pursuant to this Section 7.2.  The Buyer shall be deemed to have satisfied
     its obligations with respect to a Demand Registration under this Section
     7.2(a) only when the registration statement has been declared effective.

          (b)  Selection of Underwriters.  If any Demand Registration is an
     underwritten offering, the Selling Stockholders will collectively select
     a managing underwriter or underwriters of recognized national standing to
     administer the offering, which shall be reasonably satisfactory to the
     Buyer.

7.3  Restrictions on Public Sale.

          (a)  Public Sale by Holders of Registrable Securities. Each
     Securityholder, if requested by the managing underwriter or underwriters
     for any underwritten Piggyback or Demand Registration in which such
     Securityholder is not participating or by the Securityholders holding a
     majority of the Registrable Securities being registered in a Demand
     Registration in which such Securityholder is not participating and which
     is not being underwritten, agrees not to effect any public sale or
     distribution of Registrable Securities, including a sale pursuant to Rule
     144 (or any similar provision then in force) under the Act, during the
     five business days prior to, and during the 90-day period (or such shorter
     period as may be agreed to by the parties hereto) beginning on, the
     effective date of such Piggyback or Demand Registration (except as part
     of such Piggyback or Demand Registration) or such earlier time as all the
     shares of CompuDyne Common Stock included in such registration statement
     have been disposed of pursuant thereto.

          (b)  Public Sale by the Buyer and Others.  If requested by the
     managing underwriter or underwriters for any underwritten Piggyback or
     Demand Registration or by the Securityholders holding a majority of the
     Registrable Securities being registered in a Demand Registration which is
     not being underwritten, the Buyer will (i) not effect any public sale or
     distribution of CompuDyne Common Stock for its own account (or securities
     convertible into or exchangeable or exercisable for CompuDyne Common
     Stock) during the 10 business days prior to, and during the 90-day period
     beginning on, the effective date of such Piggyback or Demand Registration
     (except as part of such registration or pursuant to registrations on Forms
     S-4, S-8, or any successor form to such forms) and with respect to any
     Demand Registration the Buyer will not effect any such sale or
     distribution during the period commencing on the date of filing such
     Demand Registration and ending on the sixtieth day following the effective
     date of such Demand Registration, and (ii) use reasonable efforts to cause
     each other holder of CompuDyne Common Stock (or securities convertible
     into or exchangeable or exercisable for CompuDyne Common Stock) purchased
     from the Buyer at any time after the date of this Agreement (other than
     in a registered public offering) to agree not to effect any public sale
     or distribution of any such securities during such period (except as part
     of such Piggyback or Demand Registration, if otherwise permitted).

7.4  Registration Expenses.  All of the costs and expenses of each Registration
     hereunder will be borne by the Buyer, including the fees and expenses of
     the counsel and accountants for the Buyer (including the expenses of any
     "cold comfort" letters required by or incident to such performance), and
     all other costs and expenses of the Buyer incident to the preparation,
     printing and filing under the Act of the Registration Statement (and all
     amendments and supplements thereto) and furnishing copies thereof and of
     any preliminary Prospectus and the Prospectus including therein, and the
     costs and expenses incurred by the Buyer in connection with the
     qualification of the Registrable Securities under the state securities or
     "blue-sky" laws of various jurisdictions as agreed to by Buyer, which
     agreement to such choice of jurisdictions shall not be unreasonably
     withheld; provided, that, the Buyer shall not bear costs and expenses of
     any Securityholders comprising underwriters commissions, brokerage fees,
     transfer taxes, or the fees and expenses of any counsel (including counsel
     for the underwriters), accountants or other representatives retained by
     any Securityholder and provided, further, that the Buyer shall not be
     required to purchase insurance in lieu of indemnification.

7.5  Rule 144.  The Buyer agrees that at all times after the Closing Date, it
     will use its best efforts to file in a timely manner all reports required
     to be filed by it pursuant to the Securities Exchange Act of 1934, as
     amended (the "Exchange Act").  At any time and upon request of a
     Securityholder, the Buyer will furnish such Securityholder and others with
     such information as may be necessary to enable the Securityholder to
     effect sales of CompuDyne Common Stock pursuant to Rule 144 under the Act. 
     Notwithstanding the foregoing, the Buyer may deregister any class of its
     equity securities under Section 12 of the Exchange Act or suspend its duty
     to file reports with respect to any class of its securities pursuant to
     Section 15(d) of the Exchange Act if it is then permitted to do so
     pursuant to the Exchange Act and the rules and regulations thereunder.

7.6  Other Registration Rights.  Subject to the proviso below, the Buyer will
     not grant any person any demand or piggyback registration rights with
     respect to CompuDyne Common Stock (or securities convertible into or
     exchangeable or exercisable for CompuDyne Common Stock) other than (a)
     piggyback rights, substantially the same as those contained herein,
     granted to officers, directors, consultants or employees of the Buyer or
     its subsidiaries who acquire CompuDyne Common Stock (b) piggyback
     registration rights ("new piggyback rights") that would be consistent with
     the terms of this Article VII and which would provide that the
     Securityholders have a piggyback right upon the exercise of such new
     piggyback rights and shall be included in such registration statement
     before the inclusion of any shares pursuant to the exercise of the new
     rights and (c) demand registration rights ("new demand rights") that may
     not be exercised until at least 90 days after the right to a Demand
     Registration initially becomes exercisable pursuant to paragraph 7.2(a)
     above and which provide that the Securityholders have a piggyback right
     upon the exercise of such new demand rights; provided, however, that to
     the extent that the Buyer grants to any person registration rights with
     respect to any shares of CompuDyne Common Stock of the Buyer having
     provisions more favorable to the holders thereof than the provisions
     contained in this Agreement, the Buyer will confer comparable rights to
     the holders of Registrable Securities in this Agreement, but only while
     this Agreement remains in effect.  The Buyer will not grant any
     registration rights that would permit any person (including the Buyer) the
     right to piggyback on any Demand Registration.

7.7  Definition.  "Registrable Securities" means the shares of CompuDyne Common
     Stock issuable upon conversion of the Preference Stock, and the Notes, as
     more fully described in Exhibits 1.2 and 5.5 attached hereto; provided,
     however, that any share of CompuDyne Common Stock that (i) has been
     effectively registered under the Act and disposed of in accordance with
     the registration statement covering it or (ii) has been sold to the public
     pursuant to Rule 144 (or any similar provision then in force) under the
     Act shall not be a Registrable Security.


7.8  Other.  The Buyer will follow the registration Procedures customarily
     followed in this type of transaction and will enter into underwriting,
     indemnity and other documents customarily required in this type of
     transaction.  The Securityholders agree to cooperate with the Buyer in
     connection with the preparation and filing of the registration statement
     and accompanying prospectus.

          (b)  No party hereto shall have any liability or further obligation
     to any other party to this Agreement except as stated in this Section 8.2
     and in Sections 4.2(b), 4.3 and 4.6.


                                 ARTICLE IX

9.1  Survival of Representations and Warranties; Covenants.  All
     representations and warranties contained herein and the covenants
     contained in Sections 4.2, 4.3, 4.6 and 4.8 and Article VII hereof shall

     the date of this Agreement.

9.2  Indemnification.   

          (a)  Subject to the conditions and limitations of this Article IX,
     each Seller, severally based upon the percentage of Preference Stock each
     Seller owns immediately after the Closing, agrees to indemnify and hold
     Buyer harmless from and against any and all damages, losses and expenses
     (including reasonable attorneys' fees) sustained by the Buyer ("Damages")
     arising out of any breach of warranty or misrepresentation contained in
     this Agreement or any Schedule to this Agreement made by either of them
     or the Company.

          (b)  Subject to the conditions and limitations of this Article IX,
     the Buyer agrees to indemnify and hold the Company and each Seller
     harmless from and against any and all Damages arising out of any breach
     of warranty or misrepresentation contained in this Agreement or any
     Schedule to this Agreement made by it.

          (c)  In determining the amount of any Damages pursuant to this
     Section 9.2:

               (i)  No Damages shall be deemed sustained by reason of any taxes
          measured by income payable by the party making a claim for
          indemnification (the "Indemnified Party") as a result of (A) the
          inclusion in income of any amount in one or more taxable years, if,
          as a result of the inclusion, the Indemnified Party is or would be
          entitled to exclude or to deduct from income such amount in other
          taxable years subsequent to the Closing Date, or (B) the disallowance
          of a deduction from income or a credit against taxes of any amount
          in one or more taxable years, if, as a result of such disallowance,
          the Indemnified Party is or would be entitled to exclude or to deduct
          from income or credit against taxes such amount in other taxable
          years subsequent to the Closing Date.

               (ii) There shall be a credit for any reduction in tax
          liabilities of the Indemnified Party as a result of the state of
          facts giving rise to any claim of damages, losses or expenses, such
          credit to be the amount of actual cash savings realized or to be
          realized by the Indemnified Party.

9.3  Conditions of Indemnification.  Indemnified Party agrees to give prompt
     written notice to the party or parties indemnifying the Indemnified Party
     (the "Indemnifying Party") of any claim against the Indemnified Party
     which might give rise to a claim by the Indemnified Party against the
     Indemnifying Party under the terms of this Agreement, stating the nature
     and basis of such third-party claim or litigation.  Indemnified Party
     agrees to (i) keep the Indemnifying Party fully informed, (ii) use all
     reasonable efforts to defend such claim or litigation with substantially
     the same action and steps to contest, defend, resolve, settle or
     compromise such claim as it would otherwise take with respect to similar
     claims in the ordinary course of its business and (iii) present any
     defense reasonably suggested by the Indemnifying Party or the Indemnifying
     Party's counsel.  The Indemnifying Party shall have the right to be
     represented in such claim or proceeding by legal counsel and accountants,
     at its own expense.  So long as there exists any right to indemnification
     by the Indemnifying Party, the Indemnified Party will not make any
     settlement of any claim or litigation which might give rise to a right to
     indemnification from the Indemnifying Party without the consent of the the
     Indemnifying Party, provided that such consent shall not be unreasonably
     withheld.  In the event that the Indemnified Party is able to settle a
     claim or litigation by payment of a sum of money and the Indemnifying
     Party disagrees with the proposed settlement, the Indemnified Party may
     tender the further defense of such litigation to the Indemnifying Party,
     provided that the Indemnifying Party fully indemnify the Indemnified Party
     against the final outcome of such litigation for all damages, costs and
     attorneys' fees.

9.4  Limitations on Indemnification.  The Indemnified Party shall be entitled
     to indemnification under this Article IX only to the extent that the
     aggregate amount of damages exceeds $50,000 (after which point the the
     Indemnifying Party shall be obligated to indemnify the Indemnified Party
     from all Damages including the first $50,000).  The limit of the
     Indemnifying Party's liability under this Agreement for all Damages in the
     aggregate from any and all claims, actions, suits, liabilities, losses,
     damages, expenses and amounts paid in settlement shall be $1,900,000
     (after which point the Indemnifying Party will have no obligation to
     indemnify  the Indemnified Party from and against further such Damages). 
     In no event shall Seller be liable for any Damages or any other payment
     under this Agreement with respect to any claim, action, suit, liability,
     loss, damage, or expense which has not been asserted, instituted,
     determined or paid within two years from the date of this Agreement.

     which commits the Company to continue their employment.

     The Company has a profit sharing plan for senior employees (copy of
     announcement letter dated May 9, 1995 previously provided to Buyer).

     The Company had a production-based bonus program for factory workers which
     the Company cancelled at the end of July.  It is expected to be replaced
     (as is the profit sharing plan for salaried employees) with a general
     profit sharing plan for all employees.

     The Company has a Shareholders' Agreement (copy previously provided to
     Buyer).

     The Company has no union.

     The Company has a standard group health plan for employees with Blue
     Cross.  The Company also provides minor amounts of Group Life Insurance.

     Vacation and related policies are covered in the Employee Handbook.


Schedule 2.13

     The Company's only litigation since acquiring the Company in March of 1991
     has been with an ex-employee, Bob Wheeler.  He was sued by the Company
     several years ago for removing company documents (customer list,
     engineering drawings) and attempting to compete with us using these
     materials.  Wheeler countersued for business interference.  Over a year
     ago we concluded that the suit was costing us more than it was worth since
     we no longer perceived Wheeler as a competitive threat.  Papers were
     drafted for a settlement which involved the return of the Company's
     documents, but these were never executed and the suit has been dormant
     since.  We feel the issue is moot and any competitive advantage from the
     documents has been largely dissipated by time and our addition of many new
     customers in the interim.


Schedule 4.1

     During the interim MASI replaced its Sales Manager.  In connection with
     this, it has committed to a bonus to the new Sales Manager based on sales
     results.

     MASI plans to terminate its accountant and replace him with a combination
     of resources from CompuDyne.  This may occur prior to the closing of this
     transaction.

Schedule 3.5

     Suntec had sales of $47,000 in July 1995 and has a continuing low
     level of sales in August 1995.

                                                              EXHIBIT 99.2

Business under the agreements, contracts, leases, licenses, and other
arrangements referred to in the definition of Acquired Assets either (i) to

after the Closing, and (e) any and all Liabilities related to or arising out of
the Comprehensive Environmental Response, Compensation and Liability Act of
1980, the Resource Conservation and Recovery Act of 1976, and the Occupational
Safety and Health Act of 1970, each as amended, together with all other laws
(including rules, regulations, codes, plans, injunctions, judgments, orders,
decrees, rulings, and charges thereunder) of federal, state, local, and foreign
governments (and all agencies thereof) concerning pollution or protection of the
environment, public health and safety, or employee health and safety, including
laws relating to emissions, discharges, releases, or threatened releases of
pollutants, contaminants, or chemical, industrial, hazardous, or toxic materials
or wastes into ambient air, surface water, ground water, or lands or otherwise
relating to the manufacture, processing, distribution, use, treatment, storage,
disposal, transport, or handling of pollutants, contaminants, or chemical,
industrial, hazardous, or toxic materials or wastes; provided, however, that the
Assumed Liabilities shall not include (i) any Liability of Seller for income,
transfer, sales, use, and other taxes arising in connection with the
consummation of the transactions contemplated hereby (including any income taxes
arising in connection with the consummation of the transactions contemplated
hereby (including any income taxes arising because the Seller is transferring

incurred in connection with this Agreement and the transactions contemplated
hereby, or (iii) any Liability or obligation of Seller under this Agreement (or

     3.   CONSIDERATION AND PAYMENT.  The consideration for the Acquired Assets
is as follows:

          3.1  Shares of Common Stock.  At Closing, Buyer shall deliver to
Seller a certificate or certificates representing 850,000 shares of Buyer's
common stock, $.001 par value (the "Buyer Common Stock"), which shares shall be
duly authorized, validly issued, fully paid and nonassessable.  Buyer and Seller
hereby agree that, for the purpose of this Agreement, the value of the shares
of Buyer Common Stock delivered to Seller hereunder shall be equal to the Asset
Net Value of the Acquired Assets as of the Closing Date as determined in
accordance with Section 5.1 hereof.

          3.2  Royalty Payments.  As further consideration for the sale and
purchase of the Acquired Assets as set forth herein, Buyer shall pay to Seller
or Seller's assignee a royalty equal to Two Percent (2%) of Buyer's net
installed sales and other revenues (the "Royalties") for a period commencing on
the Closing Date and ending on the later of (i) thirty (30) years after the
Closing Date and (ii) the date on which all earned Royalties have been paid in
full (the "Royalty Period").  The Royalties shall be paid monthly on the
fifteenth day of each month based on Buyer's net installed sales and other
revenues during the immediately preceding calendar month.  Buyer shall prepare
and deliver to Seller, no later than the fifteenth day of each month during the
Royalty Period, a statement in reasonable detail with respect to the Buyer's net
installed sales and other revenues earned during the preceding calendar month
prepared in accordance with generally accepted accounting principles
consistently applied and certifying the Royalties due thereon based on the net
installed sales and other revenues in accordance with this Section 3.2.  Such
statement shall be signed by an officer of Buyer and accompanied by a check in
the amount of the Royalties then payable as set forth in the statement.  Seller,
or its designated representative, may audit such statements and Buyer shall
fully cooperate with Seller or its representatives in the performance of such
audit including, without limitation, providing Seller or its representative with
full opportunity to inspect the relevant books and records of Buyer and to
interview Buyer's officers, employees, consultants and accountants.  At any time
that Royalties becoming due under this Section 3.3 are not paid when due and
remain past due, Buyer shall not pay any dividends on any class of its capital
stock or make any other distribution or payment on account of or in redemption,
retirement and purchase of such capital stock or make payment of any portion of
principal or interest on any debt owing to any officer, employee, shareholder
or affiliate of Buyer.  Furthermore, Buyer covenants and agrees that the
Royalties shall be an obligation of Buyer senior to all other debt obligations
of Buyer and Buyer shall execute such documents and take such steps as Seller
may reasonably require to evidence such senior status of the Royalties.  Any
Royalties not paid when due shall bear interest from the due date thereof until
paid at the variable annual rate of 2% over the Prime Rate (as defined in the
Buyer Note).

          3.3  Sublease.  Buyer and Seller shall enter into a sublease agreement
in substantially the form as Exhibit 3.3, attached hereto and made a part
hereof, (the "Gaithersburg Premises Sublease") pursuant to which Seller shall
sublease to Buyer and Buyer shall sublease from Seller that portion of the
premises leased by Seller located at 205 Perry Parkway, Suite 8, Gaithersburg,
Maryland (the "Premises") and currently occupied by the Seller's Suntec
Division.

          3.4  Assumption of Liabilities.  Buyer shall, pursuant to this
Agreement, assume the Assumed Liabilities.

     4.   CLOSING, TITLE, RISK OF LOSS, ETC.  Completion of the transactions
contemplated by this Agreement shall be effected at a closing (the "Closing")
to be held at the offices of Tyler Cooper & Alcorn, CityPlace I, 35th Floor,
Hartford, Connecticut on August 21, 1995, commencing at 10:00 A.M., or at such
other place, date and time as shall be mutually agreed upon by the parties.  The
date of the Closing is referred to herein as the "Closing Date".  Title and risk
of loss to the Acquired Assets shall pass to Buyer upon Closing.

     5.   SALE OF BUYER COMMON STOCK.  At the Closing, Seller shall sell to
Silberdick and Silberdick shall purchase from Seller the Buyer Common Stock. 
The consideration for the Buyer Common Stock shall be as follows:

          5.1  Promissory Note.  At the Closing, Silberdick shall deliver to
Seller Silberdick's promissory note in the principal amount of Seventy-Nine
Thousand Dollars ($79,000) (which principal amount is subject to adjustment as
set forth below) in substantially the form set forth in Exhibit 5.1 attached
hereto and made a part hereof (the "Silberdick Note"; such term shall also apply
to any extensions, renewals, modifications or replacements therefor), which
shall be duly executed by Silberdick with all appropriate blanks completed.  The
principal amount of the Silberdick Note is intended to equal the sum of (i) the
current book value of the Acquired Assets less (ii) the amount of the Assumed
Liabilities (the "Asset Net Value"), all as reflected on the books of Seller 
on June 30, 1995 adjusted for assets or liabilities created in the ordinary 
course of business between June 30, 1995 and the Closing Date.  Such newly 
created assets and liabilities will be recorded in accordance with
generally accepted accounting principles consistently applied.  The initial
principal amount set forth above represents the Asset Net Value as of the date
of the Suntec Balance Sheet.  Within thirty (30) days after the Closing Date,
Coopers & Lybrand, Seller's independent accountants, shall determine the Asset
Net Value as of the Closing Date based on the Asset Net Value as reflected on
the Suntec Balance Sheet adjusted only for changes in the Asset Net Value as a
result of business conducted by the Suntec Division in the ordinary course
between the date of the Suntec Balance Sheet and the Closing Date.  Such
determination by Coopers & Lybrand shall constitute a compilation, not an audit
or review except as to determining the proper accounting treatment of the newly
created assets and liabilities.  The principal amount of the Silberdick Note
shall be adjusted to equal the Asset Net Value so determined, but in no event
shall the principal amount of the Silberdick Note exceed One Hundred Thousand
Dollars ($100,000).  In the event the Asset Net Value as determined by the
independent accountant exceeds $100,000, Seller shall select, and Buyer shall
reconvey to Seller, certain assets the value of which when retained by Seller
shall cause the Asset Net Value to be as close to, but not above, $100,000 as
is practicable.  The fee payable to the independent accountant with respect to
the determination of the Asset Net Value shall be borne equally by Buyer and
Seller.

          5.2  Pledge of Stock.  Silberdick shall pledge his shares of all of
the capital stock of any class of Suntec owned by him (including, but not
limited to the Buyer Common Stock) (the "Silberdick Shares") to Seller to secure
payment of the Silberdick Note.  Silberdick shall also cause (a) each person
(including individuals, corporations, partnerships or other business
organizations) that controls, is or are controlled by or is or are under common
control with Silberdick, or (b) each (i) corporation or organization (other than
Suntec) of which Silberdick is an officer or partner or is, directly or
indirectly the beneficial owner of ten percent or more of any class or equity
securities, (ii) trust or other estate in which Silberdick has any substantial
interest or as to which Silberdick serves as trustee or in a similar capacity,
and (iii) any relative or spouse of Silberdick, or any relative of such spouse,
who has the same home as Silberdick or who is a director or officer of Suntec
or any of its parents or subsidiaries (the parties described in (a) and (b)
above being referred to hereinafter collectively as the "Silberdick Affiliates"
and singularly as a "Silberdick Affiliate") to pledge any class of equity
securities of Suntec beneficially owned by any Silberdick Affiliate (the
"Silberdick Affiliate Shares") as further security for the repayment of the
Silberdick Note.  The foregoing shall apply to any Silberdick Affiliate whether
such Silberdick Affiliate is or becomes a Silberdick Affiliate on or after the
date of this Agreement.  At the Closing, Silberdick shall deliver to the Seller
a certificate or certificates representing 100% of the Silberdick Shares and
100% of the Silberdick Affiliate Shares together with stock powers in blank and
a Stock Pledge Agreement, in substantially the form set forth on Exhibit 5.2,
attached hereto and made a part hereof, executed by Silberdick.  In the event
of a Silberdick Event of Default, as defined in the Silberdick Note, Buyer's
sole and only recourse against Silberdick or the Silberdick Affiliates for the
payment of Silberdick's obligations under the Silberdick Note shall be derived
from Seller's rights with respect to the Silberdick Shares or the Silberdick
Affiliate Shares under the Stock Pledge Agreement except that, in the event that
Silberdick or any Silberdick Affiliate requires the Seller to dispose of the
Silberdick Shares or the Silberdick Affiliate Shares at a public or private sale
pursuant to the provisions of Section 42a-9-505(2) of the Connecticut General
Statutes, Silberdick shall remain personally liable for the amount of any
deficiency between the amount recovered from such sale and the outstanding
indebtedness under the Silberdick Note.  The foregoing limitation shall not
affect Seller's rights, which are unconditional and absolute, to declare the
indebtedness evidenced by the Silberdick Note to be immediately due and payable
upon the occurrence of any Silberdick Event of Default.  Silberdick and Buyer
hereby covenant and agree that, until and unless the Silberdick Note and all
obligations thereunder have been paid and discharged in full, (i) the issued and
outstanding shares of the capital stock of Buyer of any class (other than
Silberdick Shares or Silberdick Affiliate Shares pledged under the Stock Pledge
Agreement) shall not exceed sixty-six and two-thirds percent (66-2/3%) of the
total aggregate issued and outstanding shares of the capital stock of Buyer of
any class (including the Silberdick Shares or Silberdick Affiliate Shares
pledged under the Stock Pledge Agreement) and (ii) no shares of the capital
stock of Buyer of any class (other than the Silberdick Shares or Silberdick
Affiliate Shares pledged under the Stock Pledge Agreement) shall be issued other

thereof accruing to the Buyer or pursuant to a stock incentive plan to Buyer's

                                   attachment.

                      NON-QUALIFIED STOCK OPTION TERMS


     Corcap, Inc. ("Corcap") hereby grants to the Grantee the following Option
One and Option Two (the "Options") to purchase on or before the respective
Expiration Dates at the Purchase Price per Share for the Option Shares, which
shall be fully paid and non-assessable shares of the Common Stock of Corcap, par
value $.01 per share (the "Common Stock").

     The Options are granted subject to the following terms and conditions:

    1.    Option One shall be immediately exercisable and shall expire on August
21, 1996 (the "Option One Expiration Date").
    
    2.    Option Two shall be exercisable upon the exercise in full of Option
One and, assuming the exercise of Option One, shall terminate on August 21,
2005.  In the event the Grantee does not exercise Option One on or before the
Option One Expiration Date, Grantee's rights to both Option One and Option Two
shall expire.

     3.   The Options may be exercised according to these terms, in whole or in
part, by written notification delivered in person or by mail to Corcap's
Corporate Secretary at Corcap's executive offices in Hartford, Connecticut or
at such other location of its executive offices.  Such notification shall be
effective upon its receipt by the Corporate Secretary of Corcap on or before the
respective Expiration Date of each of Option One and Option Two, and shall be
in substantially the form attached as Exhibit A and Exhibit B, respectively,
specifying the number of shares with respect to which the appropriate Option is
then being exercised and accompanied by payment for such shares.  Neither Option
may be exercised with respect to a fractional share or with respect to fewer
than 100 shares.  In the event the Expiration Date falls on a day which is not
a regular business day at Corcap's executive offices, then such written
notification must be received at such office on or before the last regular
business day prior to the Expiration Date.  Payment is to be made by check
payable to the order of Corcap.  No shares shall be issued on exercise of either
Option until full payment for such shares has been made and all checks delivered
in payment therefor have been collected.  The Grantee shall not have any rights
of a shareholder upon exercise of either Option, including but not limited to,
the right to vote or to receive dividends, until stock certificates have been
issued to the Grantee.

     2.   Corcap shall not be required to issue any certificate or certificates
for shares purchased upon the exercise of any part of the Options prior to
(i) the admission of such shares to listing on any stock exchange on which the
stock may then be listed, (ii) the completion of any registration or other
qualification of such shares under any state or federal law or rulings or
regulations of any governmental regulatory body if required prior to such
exercise unless an exemption from registration is available, as determined by
Corcap in its sole discretion, (iii) the obtaining of any consent or approval
or other clearance from any governmental agency which Corcap shall, in its sole
discretion, determine to be necessary or advisable, and (v) the payment to
Corcap, upon its demand, of any amount requested by Corcap for withholding,
federal, state or local income or earnings taxes or any other applicable tax or
assessment (plus interest or penalties thereon, if any, caused by a delay in
making such payment) incurred by reason of the exercise of the Options or the
transfer of such shares.  The Options shall be exercised and shares issued only
upon compliance with the Securities Act of 1933, as amended (the "Act"), and any
other applicable securities laws, and the Grantee shall comply with any
requirements imposed by the Securities and Exchange Commission or any state
securities commission under such laws.  

     If the Grantee qualifies as an "affiliate" (as that term is defined in
Rule 144 ("Rule 144" promulgated under the Act), upon demand by Corcap, the
Grantee (or any person acting on his behalf) shall deliver to the Corporate
Secretary of Corcap at the time of any exercise of the Options a written
representation that upon exercising the Options he will acquire shares for his
own account, that he is not taking the shares with a view to distribution and
that he or she will dispose of the shares only in compliance with Rule 144.

     3.   The Options are not transferrable by the Grantee otherwise than by
will or by the laws of descent and distribution, and is exercisable, during the
life of the Grantee, only by him or by his guardian or legal representative. 
More particularly (but without limiting the generality of the foregoing), the
Options may not be assigned, transferred (except as provided above), pledged or
hypothecated in any way, shall not be assignable by operation of law and shall
not be subject to execution, attachment or similar process.  

     4.   Notwithstanding any other provisions:
  
     (a)  If the Grantee should die during the term of the Options, the Options
may be exercised by the person designated in the Grantee's last will and
testament or, in the absence of such designation, by the Grantee's estate, to
the full extent that the Options could have been exercised by the Grantee
immediately prior to the Grantee's death, but not later than the second
anniversary of the Grantee's death until the expiration of its original term. 


     In the event the Options are exercised by the executors, administrators,
legatees or distributees of the estate of the Optionee, Corcap shall be under
no obligation to issue shares unless Corcap is satisfied that the person or
persons exercising the Options are the duly appointed legal representatives of
the Optionee's estate or the proper legatees or distributees thereof.

     (b)  In the event of a merger, consolidation, reorganization,
recapitalization, stock dividend, stock split or other changes in corporate
structure or capitalization affecting the Common Stock, the number of shares
remaining to be exercised under the Options and the Purchase Price shall be
appropriately adjusted.  If, as a result of any adjustment under this paragraph,
the Grantee becomes entitled to a fractional share, he or she shall have the
right to purchase only the adjusted number of full shares and no payment or
other adjustment will be made with respect to the fractional share so
disregarded.

     5.   The waiver by Corcap of any provision of this Agreement shall not
operate as or be construed to be a subsequent waiver of the same provision or
a waiver of any other provision of the Agreement.

     6.   The Option shall be irrevocable during the Option period and its
validity and construction shall be governed by the laws of the State of
Connecticut.
