                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information, including "Risk Factors" and the Company's Consolidated Financial
Statements and Notes thereto, appearing elsewhere in or incorporated by
reference into this Prospectus. Except as otherwise noted, all information in
this Prospectus assumes no exercise of the Underwriters' over-allotment option.
 
                                  THE COMPANY
 
     The Company is a leading U.S.-based manufacturer of vehicle security
systems and is recognized as a technology leader in remote control vehicle
security systems, keyless entry systems and security sensor products. The
Company categorizes sales of its vehicle security systems as pre-delivery and
post-delivery sales. Pre-delivery sales are products sold in the original
equipment manufacturer ("OEM") market, for installation before delivery of a new
vehicle to the purchaser (either through factory installation by the automaker
or as a dealer-installed option or through contract installers known as
"expediters"). Post-delivery sales are products sold for installation on a
vehicle already owned by the customer (generally through retail specialty stores
and mass merchandisers).
 
     The Company's products are marketed and sold in U.S. and Canada primarily
to General Motors, Ford and Chrysler primarily through more than 9,000
automobile dealers pursuant to private label purchase agreements with these
manufacturers; more than 1,200 independent retail specialty stores; automotive
expediters; and mass merchandisers such as Sears and Best Buy. International
companies to whom the Company sells its vehicle security products are Peugeot,
Volkswagen-Audi Group France, Renault, Mitsubishi, Subaru, Toyota and Nissan as
well as to independent retail specialty stores, expediters and mass
merchandisers. In addition, the Company recently began supplying vehicle
security systems to Ford of Venezuela and Ford-Mexico.
 
     The Company sells its vehicle security systems under several brand names
including Code-Alarm(R), Mirage(TM), Chapman(R) and Anes(R), and sells its
products as private label lines under automakers' brand names, including, for
example, Mr. Goodwrench(TM) in the case of General Motors. The Company offers
basic security systems and accessory products which a customer may use to tailor
a security system to the customer's specific requirements. Products are actively
promoted to dealers and retailers. The Company also provides support services to
dealers, including technical and installation service.
 
     The Company's primary business objective is to expand as a leading
designer, manufacturer and marketer of vehicle security systems, through further
penetration of its existing customer base as well as the addition of new
customers and by expanding its presence in the European market. Key elements of
the Company's business strategy include: (i) focusing on its OEM customers
through distribution to dealers, direct sales to manufacturers for factory floor
installation and strategic alliances with other OEM suppliers; (ii) continuing
its sales to independent retail specialty stores and mass merchandisers; (iii)
expanding its European presence; (iv) enhancing its engineering capabilities;
and (v) shortening its product development and introduction cycles while
maintaining high quality standards.
 
     The Company is a Michigan corporation, its executive offices are located at
950 E. Whitcomb, Madison Heights, Michigan 48071 and its telephone number is
(810) 583-9620.

                             Company's common stock, no par value (the "Common
                             Stock") at any time prior to maturity, unless
                             previously redeemed or repurchased, at a conversion
                             price of $          per share, subject to
                             adjustment in certain events as described herein.
                             Accordingly, each $1,000 principal amount of
                             Debentures is convertible into        shares of
                             Common Stock, subject to adjustment, for an
                             aggregate of        shares, representing
                             approximately      % of the Common Stock on a fully
                             diluted basis. See "Description of
                             Debentures -- Conversion of Debentures" and
                             "Capitalization."
 
Optional Redemption........  Redeemable at the Company's option, at any time in
                             whole or in part, at the redemption price set forth
                             herein, plus accrued interest; provided, however,
                             that prior to December 1, 1998, the Debentures may
                             not be redeemed unless the closing sale price of
                             the Common Stock equals or exceeds 140% of the then
                             current conversion price for at least 20 trading
                             days within 30 consecutive trading days ending not
                             more than ten trading days prior to the date of the
                             notice of redemption. See "Description of
                             Debentures -- Optional Redemption."
 
Repurchase at Option of
Holders upon Certain
  Events...................  Upon a Repurchase Event (as defined herein), the
                             Company is required to repurchase, at the option of
                             the holders, any Debentures delivered to it for
                             redemption at 101% of the principal amount thereof
                             plus accrued interest. A Repurchase Event is
                             generally defined to include: (i) certain
                             acquisitions of the Company voting stock such that
                             a person (other than a present holder of 5% or more
                             of the Company's capital stock) owns more than 50%
                             of the outstanding Company capital stock; (ii) a
                             change in the composition of the Board of Directors
                             such that there is a shift of a majority of its
                             members; (iii) certain consolidations, mergers or
                             sales of assets of the Company to a person (other
                             than a present holder of 5% or more of Company
                             capital stock) who, as a result, owns more than 50%
                             of the outstanding Company capital stock; (iv) the
                             acquisition by the Company of more than 30% of its
                             outstanding shares of capital stock in any 12-month
                             period; and (v) certain Company acquisitions and
                             distributions in respect to its capital stock in
                             excess of 30% of the values of such stock. See
                             "Description of Debentures -- Repurchase Event."
 
Subordination..............  The Debentures will be subordinated to all existing
                             and future Senior Indebtedness (as defined herein)
                             of the Company. There is no limitation on the
                             amount of Senior Indebtedness that may be incurred
                             by the Company. See "Description of
                             Debentures -- Subordination of Debentures."
 
Use of Proceeds............  The net proceeds from the sale of the securities
                             will be used to reduce bank indebtedness, and for
                             working capital and general corporate purposes. See
                             "Use of Proceeds."

(1) Includes patent infringement settlement costs in the amount of $4.4 million
    for the year ended December 31, 1994 and $1.8 million for the nine months
    ended September 30, 1995.
(2) The ratio of earnings to fixed charges was computed by dividing earnings by
    fixed charges. For this purpose "earnings" consists of earnings before
    income taxes and "fixed charges," and "fixed charges" consists of interest
    on indebtedness and the portion of rental expense which is deemed to be
    representative of the interest component. For the years ended December 31,
    1992 and December 31, 1994, earnings were not sufficient to cover fixed
    charges by $3.4 million and $1.2 million, respectively.
(3) Adjusted to reflect ratio of earnings to fixed charges excluding litigation
    expense.
(4) Adjusted to give effect to the sale of $10,000,000 principal amount of   %
    Convertible Subordinated Debentures due 2002, and the application of the net
    proceeds therefrom. See "Use of Proceeds" and "Capitalization."

                                  RISK FACTORS
 
     Prior to purchasing the Debentures offered hereby, prospective investors
should carefully consider, together with the other information contained herein,
each of the following risk factors which could, individually or in the
aggregate, have a material adverse effect on the Company's business and
financial condition, including working capital, and results of operations.
 
     Litigation.  The Company historically has been involved in a number of
legal disputes, many of which have resulted in litigation, both as plaintiff and
as defendant, including a number of proceedings currently pending. Damages
sought against the Company in these pending proceedings exceed in the aggregate
the entire shareholders' equity of the Company, and an unfavorable result in one
or more of these cases or in any proceeding which might arise in the future
could adversely affect the value of the Debentures and could cause the holders
of Debentures to lose their entire investment. The cost of legal proceedings and
settlements of lawsuits involving the Company was a principal cause of the
Company's lack of profitability in 1994 and has had a substantial negative
impact on the Company's results of operations in 1995 to date. As of October 26,
1995, reserved for but yet unpaid judgments against the Company amounted to an
aggregate of approximately $5.9 million; approximately $5.4 million of this
amount has been reserved for and the Company has posted a $5.9 million letter of
credit as security for this amount. See "Legal Proceedings" and Note 9 of Notes
to Consolidated Financial Statements.
 
     International Operations.  The Company began conducting European operations
in 1994 through its acquisition of Europe Auto Equipement, S.A. ("EAE"). Its
European operations expanded rapidly, with European net sales for 1994 reaching
23.8% of the Company's total 1994 net sales (28.6% of the Company's total 1994
net sales were attributable to international sales, excluding North American but
including European sales), and the Company intends to continue expanding its
international (primarily European) sales efforts and believes that such
international sales will continue to represent a significant and increasing
portion of its total sales. In addition to the other risks associated with its
business (which apply both to the Company's domestic and international efforts),
the Company's international operations, particularly its expansion into the
European market, present a number of risks to the Company's future, including
the following:
 
    - Prior to 1994, when it began conducting its European operations, the
      Company had virtually no experience manufacturing, assembling or marketing
      its products in any market outside of North America. Accordingly, it is
      subject to the normal risks associated with a new business endeavor,
      including operating losses, financial reporting, financial controls and
      financial forecasting.
 
    - The Company currently supplies automobile alarm systems to Peugeot, with
      sales in 1994 to Peugeot constituting 29.8% of the Company's European
      sales (and 22.9% and 7.1% of its international sales and total sales,
      respectively). Peugeot has recently advised the Company that it is in the
      process of consolidating its supplier base, and there is no assurance that
      Peugeot will continue to purchase automobile alarm systems from the
      Company. The loss of Peugeot sales could have a material adverse effect on
      the Company's business and financial condition, including working capital
      and results of operations.
 
    - The Company supplies its European customers with products manufactured in
      its U.S. plants. Most of the Company's European customers operate with low
      inventories or on a "just in time" basis; consequently, as product volumes
      increase, it will become increasingly difficult and costly to supply these
      customers from the Company's U.S. plants. See "Business."
 
    - In order to market its products in Europe, the Company must meet
      applicable government-imposed frequency requirements, as well as obtain
      insurance industry certifications and approvals of its products. While the
      Company has obtained such approvals in some countries, it has not obtained
      them in others. In the event these requirements change, there can be no
      assurance that the Company will be able to meet such requirements. There
      are also various other risks associated with such regulation. See "Risk
      Factors -- Regulation." The Company is also subject to certain risks
      associated with intellectual property rights. See "Risk
      Factors -- Intellectual Property."
 
     Suppliers.  The Company's products include a number of high-technology
components that are available from only a few suppliers and, in some cases, a
single supplier. The Company frequently requires large
 
                                        4
<PAGE>   10
 
volumes of such components. If the Company's suppliers are unable to fulfill the
Company's needs for such components, the Company may be unable to fill customer
orders and its business and financial condition, including working capital and
results of operations, may be materially and adversely affected. Since part of
the Company's strategy is to shorten product development and introduction
cycles, occasions may arise in the future where the Company's ability to produce
products may outpace its suppliers' ability to supply components. There can be
no assurance that the Company can continue to obtain adequate supplies or obtain
such supplies at their historical cost levels. The Company has no guaranteed
supply arrangements with any of its sole or limited source suppliers, does not
maintain an extensive inventory of components, and customarily purchases sole or
limited source components pursuant to purchase orders placed in the ordinary
course of business. Moreover, the Company's suppliers may, from time to time,
experience production shortfalls or interruptions which could impair the supply
of components to the Company. There can be no assurance that such shortages will
not occur in the future and adversely affect the Company's business and
financial condition, including working capital and results of operations. See
"Business -- Suppliers."
 
     Competition.  All markets in which the Company participates are highly
competitive, and many current or prospective competitors, including several of
the Company's OEM customers, are substantially larger and possess significantly
greater financial, marketing and technical resources than the Company. An
increase in factory-installed security systems purchased by automotive
manufacturers or the introduction of other dealer-installed security systems and
remote keyless entry systems by OEMs or existing and potential competitors could
have a material adverse effect on the Company's business and financial
condition, including working capital and results of operations. See
"Business -- Competition."
 
     Reliance on Major Customers; Cyclical Industries.  The Company supplies its
products to a number of automobile companies for installation both during the
manufacturing process and by their respective dealers. Sales to General Motors
Corporation, Ford Motor Company and Peugeot, S.A., including their retail
dealers, accounted for 10.8%, 10.9% and 8.4%, respectively, of the Company's net
sales for the year ended December 31, 1994. The Company receives payment from
General Motors, Ford and Peugeot for goods and services purchased under blanket
purchase orders covering these sales. The loss of any of these contracts could
have a material adverse effect on the Company's business and financial
condition, including working capital and results of operations. Peugeot recently
advised the Company that it is in the process of consolidating its supplier
base, and there is no assurance that Peugeot will continue to purchase
automobile alarm systems from the Company. All of these contracts are terminable
by the OEM companies at their discretion on short notice. The Company believes
the majority of its products are installed in new automobiles within a few
months of purchase. As a result, the Company's sales are highly dependent upon
the level of new automobile sales. Reductions in the sales of new automobiles
due to economic conditions, labor disturbances or other reasons could have a
material adverse effect on the Company's business and financial condition,
including working capital and results of operations. See
"Business -- Customers."
 
     Negative Interest Coverage; Leverage; Subordination.  The Company's "fixed
charges" (which consist of interest on indebtedness and the portion of rental
expense which is deemed to be representative of the interest component) have
exceeded its earnings before income taxes and fixed charges by $156,000, $3.4
million and $1.2 million, respectively, in 1991, 1992 and 1994 (there was no
coverage deficiency in 1990 and 1993). As of September 30, 1995, as adjusted for
the issuance of the Debentures and the application of the estimated net proceeds
therefrom, the Company's total long-term debt and shareholders' equity would
have been approximately $11.6 million (not including the $5.9 million letter of
credit for a litigation appeal bond) and $10.5 million, respectively, and the
Company's earnings before fixed charges and litigation expense would have been
$2.2 million, which exceeded fixed charges by $1.0 million for the nine months
ended September 30, 1995. The Company expects to incur, from time to time,
additional borrowings or other obligations which would be Senior Indebtedness,
as defined. The debt service requirements of any such additional indebtedness
could make it more difficult for the Company to make principal and interest
payments on the Debentures. The Company's ability to satisfy its obligations
will be dependent upon its future performance, which is subject to prevailing
economic conditions and financial, business and other factors, including factors
beyond the Company's control. There can be no assurance that the Company's
operating cash flow will be sufficient to meet its debt service requirements or
to repay the Debentures at maturity or that the Company will be able to
refinance the Debentures or other indebtedness at maturity. The current Senior
Indebtedness is guaranteed by
 
                                        5
<PAGE>   11
 
the Company's domestic subsidiaries and is secured by substantially all current
and future assets of the Company, including the capital stock of the Company's
subsidiaries. Any additional Senior Indebtedness is likely to require additional
security. The Debentures will be subordinated to all current and future Senior
Indebtedness of the Company. At October 26, 1995, Senior Indebtedness of the
Company was approximately $18.3 million (including a $5.9 million letter of
credit), and will be approximately $9.3 million after giving effect to the
application of the net proceeds of this Offering. There are no restrictions in
the Indenture on the incurrence of additional Senior Indebtedness. By reason of
such subordination, in the event of any insolvency, receivership, liquidation or
other reorganization of the Company, holders of Senior Indebtedness must be paid
in full before the holders of the Debentures may be paid. Accordingly, there may
be insufficient assets remaining after payment of prior claims to pay amounts
due on the Debentures. See "Description of Debentures."
 
     Short Product Life Cycles.  The market for the Company's products is
characterized by frequent new product introductions and rapid product
obsolescence. These factors typically result in short product life cycles. The
Company must continually monitor industry trends and develop new technologies
and features to incorporate into its products. Each new product cycle presents
opportunities for current or prospective competitors of the Company to gain
market share. Life cycles of individual products are typically characterized by
steep declines in unit sales, pricing and margins toward the end of a product's
life, the precise timing of which may be difficult to predict. As new products
are planned and introduced, the Company attempts to monitor closely the
inventory of older products and to phase out their manufacture in an orderly
manner. Nevertheless, the Company could experience unexpected reductions in
sales volume and prices of older generation products as customers anticipate new
products. These reductions could give rise to charges for obsolete or excess
inventory. To the extent that the Company is unsuccessful in managing product
transitions, its business and financial condition, including working capital and
results of operations, could be materially and adversely affected. See
"Business -- Business Strategy."
 
     Intellectual Property.  Although the Company has sought to protect and
believes it has protected its technologies and products by patent, copyright,
trademark and trade secret laws to the extent that it believes necessary, the
Company's intellectual property rights may be subject to infringement. There can
be no assurance that the Company's measures to protect its proprietary rights
will deter or prevent unauthorized use of the Company's technology. Furthermore,
the laws of certain countries may not protect the Company's proprietary rights
to the same extent as do the laws of the United States. The Company has applied
for patents on certain inventions in Europe; however, none of these patents has
yet been granted nor is there any assurance that patents will be granted in the
future. In addition, the Company may, from time to time, become subject to legal
claims asserting that the Company has violated intellectual property rights of
third parties. In the event a third party were to sustain a valid claim against
the Company and in the event any required license were not available on
commercially reasonable terms, the Company's business and financial condition,
including working capital and results of operations, could be materially and
adversely affected. Litigation, which could result in substantial costs to and
diversion of resources of the Company, may also be necessary to enforce
intellectual property rights of the Company or to defend the Company against
claimed infringement of the rights of others. The Company is currently engaged
as a defendant in a number of patent infringement suits. The Company is also
seeking damages and injunctive relief against a number of competitors for
allegedly infringing its U.S. patents. See "Legal Proceedings." The Company's
failure or inability to protect its existing intellectual property rights could
have a material adverse effect on the Company's business and financial
condition, including working capital and results of operations. See
"Business -- Trademarks and Patents."
 
     Regulation.  The Federal Communications Commission ("FCC") regulates the
assignment of frequencies for manufacture and sale of vehicle security remote
systems and remote keyless entry systems in the U.S. The Company has received
FCC authorization to manufacture and sell the devices it currently sells in the
U.S. In Europe, similar government agencies regulate the assignment of
frequencies; and the Company has generally been able to meet the applicable
frequency requirements. However, because insurance industry accreditation of
vehicle security systems is, in certain European countries, a prerequisite to an
automobile owner's ability to obtain vehicle theft coverage, the Company's
ability to market its products in such countries is dependent upon obtaining
such insurance industry approvals and certificates. The Company has received
French and Belgian insurance industry accreditation to manufacture and sell
electronic security systems. To

date, the Company has been unable to secure German insurance industry
accreditation required to sell its products in Germany. The Company is currently
selling its products in Spain where no insurance industry certifications are
required. European insurance industry accreditation standards are subject to
change without notice; and in 1994, significant changes in industry standards
required the development and introduction of new products for 1995. The loss of
such regulatory approvals and insurance industry accreditation or failure to
obtain these in the future could have a material adverse effect on the Company's
business and financial condition, including working capital and results of
operations. See "Business -- Regulation."
 
     Concentration on One Product Line.  The Company's concentration on the
single product line of vehicle security systems increases its vulnerability to
changes in automobile design, procurement practices of OEMs, product
substitution, consumer preferences, insurance underwriting practices and the
historical cyclicality of the motor vehicle market. As a result, a significant
change in any of the foregoing factors could have a material adverse effect on
the Company's business and financial condition, including working capital and
results of operations.
 
     Dependence on Existing Management.  Rand W. Mueller has been primarily
responsible for the development of many of the Company's products and markets.
The loss or interruption of the continued full-time services of Mr. Mueller
could have a material adverse effect on the Company. The Company has entered
into an employment agreement with Mr. Mueller which is effective through May 29,
1998, which shall be extended for additional consecutive twelve-month periods
unless terminated by the Company upon 24 months prior written notice.
 
     Shares Eligible for Sale; Demand Registration Rights.  As of October 30,
1995, the Company had 2,320,361 shares of Common Stock outstanding of which
795,612 shares were beneficially owned by executive officers and directors of
the Company. Subsequent to the Company's acquisition of EAE and Code-Alarm
Europe, Ltd. ("Code-Alarm Europe") the Company offered certain selling
shareholders of EAE and Code-Alarm Europe one-time demand registration rights,
at the Company's expense, exercisable upon 90 days' written notice to the
Company at any time before December 31, 1996, for up to 90,000 shares of the
Company's Common Stock held by them. The offers were made orally, and the
Company believes that it is unclear whether or not they constitute enforceable
obligations. If the offers are enforceable, up to 90,000 shares of Common Stock
would be subject to such registration rights on the terms described above or as
may otherwise be determined. To date, the Company has received no notice
requesting such registration. Sales of substantial amounts of such shares held
by directors or the EAE shareholders in the public market could adversely affect
the market price of the Common Stock and the Company's ability to raise
additional capital at a price favorable to the Company. See "Shares Eligible for
Future Sale."
 
     Absence of Financial Covenants.  The Indenture does not contain any
financial performance covenants. Consequently, the Company is not required under
the Indenture to meet any financial tests such as those that measure the
Company's working capital, interest coverage, fixed charge coverage or net worth
in order to maintain compliance with the terms of the Indenture. See
"Description of Debentures."
 
     No Assurance of a Public Market.  No assurance can be given that an active
market for the Debentures will develop or, if developed, will continue. If no
active market develops, it may be difficult for purchasers to resell their
Debentures. The Underwriters have advised the Company that they intend to make a
market for the Debentures although they are under no obligation to continue to
do so and if such market making were to be discontinued, investors would
encounter difficulty effecting purchase or sale transactions in the absence of
alternative market makers.
 
                                COMPANY HISTORY
 
     The Company was founded as a Michigan corporation in 1979 under the name
Fluidics Manufacturing Company and began operations in early 1980. In 1986, the
Company changed its name to Code-Alarm, Inc. In October, 1987, the Company
successfully completed its initial public offering of Common Stock. The Company
has experienced growth through a combination of internal growth and
acquisitions. The Company's subsidiaries include Tessco Group, Inc., Chapman
Security Systems, Inc., Anes Security, Inc. and Intercept Systems, Inc.
 
                                        7
<PAGE>   13
 
     The Company's acquisitions have also resulted in its growing presence in
Europe. On January 1, 1994, the Company acquired the interest of its joint
venture partner in Code-Alarm Europe, which distributes vehicle security systems
in the United Kingdom. On February 10, 1994, the Company acquired substantially
all of the outstanding capital stock of EAE, a French company having its
principal place of business near Paris, France. EAE markets and distributes
vehicle security products in Europe, primarily in France.
 
     In addition to its vehicle security systems, the Company has a contract
manufacturing operation which concentrates on cables, wire harnesses and printed
circuit board operations and also manufactures and sells, on a limited basis,
certain home security products. Neither contract manufacturing nor home security
has historically been, or is expected to be, material to the Company.
 
                                USE OF PROCEEDS
 
     The net proceeds to be received by the Company from the sale of the
Debentures offered hereby are estimated to be $9.0 million after deducting
underwriting discounts and commissions and estimated offering expenses.
 
     The Company intends to use $9.0 million of the net proceeds to partially
repay the outstanding indebtedness under its bank credit facility (which was
approximately $18.3 million, including security for a $5.9 million letter of
credit for a litigation appeal bond, at October 26, 1995). This indebtedness
bears interest at the prime rate (8.75% at October 26, 1995), or at the
Company's option, at the London Inter-Bank Offered Rate ("LIBOR") plus 2.5% for
maturities ranging from one to six months (8.125% and 8.375%, respectively, on
October 26, 1995), and was incurred for working capital purposes. The amounts
due under the bank credit facility mature on May 23, 1997.

                                DIVIDEND POLICY
 
     Historically, the Company has not paid any cash or other dividend. The
Company does not expect to pay dividends in the foreseeable future but currently
intends to retain any earnings to finance operations and future growth.
Furthermore, the Company's bank credit facility agreement prohibits the payment
of dividends.

                      SELECTED CONSOLIDATED FINANCIAL DATA
 
     The selected historical consolidated financial data for the fiscal years
1990 through 1994 are derived from the Company's audited consolidated financial
statements. The selected consolidated income and balance sheet data as of
September 30, 1995 and 1994 and for the nine months then ended, are derived from
unaudited financial statements but, in the opinion of management, reflect all
adjustments, consisting of normal recurring adjustments, except for an
additional adjustment for the patent infringement settlement of $1,825,000 in
1995, necessary for a fair statement of the financial position and results of
operations for such periods and as of such dates. The results of operations for
the nine months ended September 30, 1995 are not necessarily indicative of the
results to be expected for the full year. The Company did not pay any cash or
other dividends in the periods presented below. The information below should be

(2) The ratio of earnings to fixed charges was computed by dividing earnings by
    fixed charges. For this purpose "earnings" consist of earnings before income
    taxes and "fixed charges," and "fixed charges" consist of interest on
    indebtedness and the portion of rental expense which is deemed to be
    representative of the interest component. For the years ended December 31,
    1991, 1992 and 1994 earnings were not sufficient to cover fixed charges by
    $156,000, $3.4 million and $1.2 million, respectively.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
     Since its founding in 1979, the Company has evolved into a leading
U.S.-based manufacturer of vehicle security systems. Since 1990, the Company has
realized substantial growth in net sales primarily as a result of internal
growth and acquisitions. The Company's acquisition of Code-Alarm Europe and EAE
in early 1994 has resulted in a significant and growing presence in Europe.
 
     The Company is involved in a patent infringement suit involving a shock
sensing device. The damage portion of the trial was completed in January 1995
and at December 31, 1994, the Company recorded an accrual for damages of
approximately $4.2 million. In June 1995, the Company received information from
the United States District Court that the damages would total $6.0 million.
Accordingly, the Company recorded an additional accrual for damages of $1.8
million in 1995.
 
     The following table sets forth, for the periods indicated, earnings data as
a percentage of net sales of the Company:

  Nine Months Ended September 30, 1995 Compared to Nine Months Ended September
30, 1994
 
     The Company's consolidated net sales increased $93,000, or less than 1.0%,
for the quarter ended September 30, 1995 as compared to the quarter ended
September 30, 1994. For the nine months ended September 30, 1995, consolidated
net sales decreased $1.6 million, or 2.8%, to $54.8 million as compared to $56.4
million for the nine months ended September 30, 1994. The decrease is
attributable to a decline of $1.6 million, or 7.9%, in the quarter ended June
30, 1995. The nine month results were primarily due to a decrease in sales to
mass merchandisers and independent dealers in the quarter ended June 30, 1995
and were partially offset by increases in OEM and expediter sales in the quarter
ended September 30, 1995. The Company expects sales in the quarter ended
December 31, 1995 to be slightly below sales for the comparable period in 1994,
with higher OEM sales in Europe being offset by a decrease in domestic OEM and
independent dealer sales.
 
     The Company's consolidated gross profit increased $102,000, or 1.5%, for
the quarter ended September 30, 1995, as compared to the quarter ended September
30, 1994. For the nine months ended September 30, 1995, consolidated gross
profit decreased $1.5 million, or 7.3%, to $19.5 million as compared to $21.0
million for the nine months ended September 30, 1994. As a percentage of
consolidated sales, gross profit decreased to 35.6% in the nine months ended
September 30, 1995 from 37.4% in the comparable period
 
                                       11

of 1994. The decrease was due to the Company's emphasis on OEM sales in both
Europe and the United States primarily due to start up manufacturing problems
with the Company's European products production in the United States in the
first two quarters of 1995. The OEM sales have lower profit margins, but are
generally characterized by lower selling costs, than retail sales. The Company
expects continued lower gross profit margin in the remainder of 1995 due to
continued emphasis on OEM sales.
 
     Consolidated operating expenses increased $145,000, or 2.5%, for the
quarter ended September 30, 1995 as compared to the quarter ended September 30,
1994. For the nine months ended September 30, 1995, consolidated operating
expenses decreased $901,000, or 4.9%, to $17.5 million as compared to $18.4
million for the nine months ended September 30, 1994. The decrease in
consolidated operating expense was attributable to decreased sales and marketing
expenses, partially offset by increases in engineering and product development
costs. The Company expects to sustain decreases in marketing and administration
expenses as a result of continued emphasis on OEM sales, but expects engineering
and product development costs to level off for the remainder of the year.
 
     As a result of the foregoing, the Company earned consolidated income from
operations of $996,000 in the quarter ended September 30, 1995 compared to $1.0
million in the quarter ended September 30, 1994. Consolidated income from
operations declined $641,000, or 23.6%, for the nine months ended September 30,
1995, to $2.1 million as compared to $2.7 million for the nine months ended
September 30, 1994.
 
     Interest expense increased $531,000 in the nine months ended September 30,
1995, or 124.9%, to $956,000 as compared to $425,000 for the nine months ended
September 30, 1994. Increases are attributable to higher interest rates and
increased indebtedness associated with European Operations.
 
     Other expenses for the nine months ended September 30, 1995 increased by
$1.8 million, to $1.9 million as compared to $88,000 for the nine months ended
September 30, 1994. The increase was attributable to the accrual in the first
half of the year of an additional $1.8 million for damages, including interest
and costs, related to a patent infringement judgment on the ETC litigation.
 
     The Company had an effective domestic income tax rate of 34% on current
operating income. Income taxes on foreign operations were approximately 33%. In
the third quarter of 1995, the Company charged off state and foreign tax refunds
determined to be uncollectable in the amount of $210,000.
 
     As a result of the foregoing, the Company earned consolidated net income of
$430,000 in the quarter ended September 30, 1995 compared to $467,000 in the
quarter ended September 30, 1994. The Company recorded a net loss of $735,000,
or $0.32 per share, for the nine months ended September 30, 1995, compared to
net earnings of $1.4 million, or $.60 per share, for the nine months ended
September 30, 1994.
 
  Year Ended December 31, 1994 Compared to Year Ended December 31, 1993
 
     The Company's consolidated net sales for 1994 increased $23.4 million, or
46.7%, to $73.5 million as compared to $50.1 million in 1993. Excluding the
effect of acquisitions ("EAE" and the remaining interest in Code-Europe, Ltd.),
consolidated net sales increased $5.9 million, or 11.8%, in 1994. The
non-acquisition related sales increases resulted primarily from increases in
expediters, retail and General Motors/Ford sales volumes.
 
     The Company's consolidated gross profit for 1994 increased $7.7 million, or
38.7%, to $27.6 million as compared to $19.9 in 1993. Excluding the effect of
acquisitions, consolidated gross profit for 1994 increased $1.4 million, or
7.0%. As a percentage of consolidated sales, gross profit decreased to 37.6% in
1994 from 39.8% in 1993. Such decreases were primarily due to launch costs
associated with the introduction of the Euro Alarm in the fourth quarter of
1994.
 
     Consolidated operating expenses for 1994 increased $7.0 million, or 39.8%,
to $24.6 million as compared to $17.6 million in 1993. Excluding the effect of
acquisitions, consolidated operating expenses for 1994 increased $1.1 million,
or 6.3%. Increases in consolidated operating expenses are attributable to
acquisitions as well as other sales, marketing and product development efforts.
 
                                       12
<PAGE>   18
 
     As a result of the foregoing, consolidated income from operations for 1994
increased $677,000, or 28.6%, to $3.1 million as compared to $2.4 million for
1993. The increase was due to the acquisition of EAE and increased volume
through General Motors and Ford.
 
     Interest expense for 1994 increased $367,000, or 131.6%, to $646,000 as
compared to $279,000 for 1993. The increase was due to increased interest rates,
the acquisition of EAE and debt incurred in connection with the following items:
(i) financing sales increases, (ii) the acquisition of an important patent and
(iii) the Company's decision to repurchase stock held by two former directors at
below market prices as of the date of repurchase.
 
     Other expenses/(income) for 1994 increased $156,000, or 274.5%, to $99,000
as compared to income of $57,000 for 1993. Other expenses consisted of estimated
costs associated with a judgment to be entered against the Company in the patent
infringement lawsuit, Code-Alarm v. Electromotive Technologies Corporation,
United States District Court, Eastern Division, 87-CV-74022-DT. The amount
recorded included the Company's estimate at that time of damages, interest and
legal fees to be awarded the Plaintiff, as well as expenses that the Company had
already incurred, and estimated expenses that might be incurred in an appeal of
the judgment.
 
     The Company's effective income tax rate for the year ended 1994 was 34.0%.
 
     As a result of the foregoing, the Company incurred a consolidated net loss
of $1.4 million, or $0.58 per share, for the year ended December 31, 1994,
compared to a net profit of $1.5 million, or $0.63 per share, for the year ended
December 31, 1993. Excluding non-recurring expenses related to litigation, the
Company earned a profit of $1.5 million or $0.64 per share for the year ended
December 31, 1994.
 
  Year Ended December 31, 1993 Compared to Year Ended December 31, 1992
 
     The Company's consolidated net sales for 1993 increased $4.4 million, or
9.7% to $50.1 million as compared to $45.7 million in 1992. This increase was
primarily due to increases in sales of private label vehicle security products
to General Motors, Ford and Chrysler dealerships. Sales figures were also
affected by a price increase on vehicle security products in the first quarter
of 1993.
 
     The Company's consolidated gross profit for 1993 increased $6.5 million, or
48.8%, to $19.9 million as compared to $13.4 million in 1992. Such increases
were primarily due to cost efficiencies related to increases in volume in the
vehicle security product sales area.
 
     Consolidated operating expenses for 1993 increased $510,000, or 3.0%, to
$17.5 million as compared to $17.0 million in 1992. The relatively small amount
of operating expense increase resulted from the Company completing its efforts
to consolidate its operations by eliminating separate business units and closing
operations of the facility located at 32380 Edward, Madison Heights, Michigan.
Such measures helped to reduce operating expenses during the year by eliminating
duplicate administrative functions. Also in 1993, the Company implemented
several measures to reduce overall operating costs, including cost savings
policies on travel and entertainment costs and sales and marketing projects.
These savings were partially offset by increased costs associated with
litigation expenses. Higher than normal litigation expenses are expected to
continue until cases currently in litigation are completed.
 
     As a result of the foregoing, consolidated income from operations for 1993
increased $6.0 million, or 154.5%, to $2.4 million as compared to a loss from
operations of $3.6 million for 1992.
 
     Interest expense for 1993 decreased $146,000, or 34.5%, to $279,000 as
compared to $425,000 for 1992. Increased cash flow from operations, primarily
due to profits, contributed to a reduction of borrowing during 1993.
 
     The Company's effective income tax rate for the year ended 1993 was
approximately $28.0%. That effective income tax rate differed from the statutory
rate of 34.0% principally as a result of the utilization of an operating loss
carry-forward of approximately $479,000.
 
                                       13
<PAGE>   19
 
     As a result of the foregoing factors, the Company reported consolidated net
income for the year ended December 31, 1993 of $1.5 million, or $0.63 per share,
as compared to a net loss of $2.9 million, or $1.16 per share, for 1992.
 
EFFECT OF INFLATION
 
     The Company does not believe that inflation has had a material impact on
its operations over the past three years.

     Quarterly earnings per share calculations for the periods indicated are
based on the weighted average number of shares outstanding for the quarter then
ended. Annual earnings per share calculations are based on weighted average
number of shares outstanding for the twelve month period then ended. Due to
fluctuations in the weighted average number of shares outstanding, the sum of
the earnings per share calculations for each quarter will not necessarily equal
the calculated earnings per share for the twelve month period.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's consolidated working capital was $13.7 million at September
30, 1995 compared to $12.7 million at December 31, 1994. The current ratio
(current assets divided by current liabilities) as of September 30, 1995 is 1.83
to 1, compared to 1.95 to 1 at December 31, 1994.
 
     Net cash used in operating activities for the first nine months of 1995 was
$406,000, including $1.3 million of depreciation and amortization charged during
the nine months ended September 30, 1995. Cash consumed during the first nine
months reflect an increase in inventories and accounts receivable of
approximately $3.5 million. The Company experienced a $3.7 million increase in
finished goods inventory in Europe, most of which was attributable to the
Company's efforts to meet expected customer requirements. Lower than anticipated
European sales volumes also contributed to this higher than normal inventory
level. This increase was partially offset by an increase of accounts payable in
the amount of $2.5 million.
 
     As of October 26, 1995, $1.4 million of the $13.8 million revolving credit
facility was unused and available. Additionally, $7.0 million and $1.0 million
of amounts outstanding under the revolving line of credit were borrowed under
the LIBOR option available to the Company at interest rates of 8.375% and
8.125%, respectively.
 
     During the first nine months of 1995, the Company concluded a loan
agreement with NBD Bank. Under the terms of the agreement, the Company has
secured a $13.8 million revolving credit facility, $1.3 million in secured notes
and $2.2 million in unsecured notes. The Company has used these facilities for
operating capital and to provide financing for an appeal bond in the amount of
$5.9 million for the patent infringement litigation.

     The Company historically has been involved in a number of legal disputes,
many of which have resulted in litigation, both as plaintiff and as defendant,
including a number of proceedings currently pending. The cost of legal
proceedings and settlements of lawsuits involving the Company has been a
principal cause of the Company's lack of profitability in 1994 and has had a
substantial negative impact on the Company's results of operations in 1995 to
date. See "Risk Factors -- Litigation" and "Legal Proceedings."
 
                   CHANGES IN COMPANY'S CERTIFYING ACCOUNTANT
 
     Effective July 24, 1995 the Board of Directors of the Company, based on the
recommendation of the Audit Committee, appointed Deloitte & Touche LLP as the
independent accountants of the Company. Deloitte & Touche LLP replaced Coopers &
Lybrand L.L.P. (dismissed July 19, 1995) the Company's previous independent
accountants. The reports of Coopers & Lybrand L.L.P. on the financial statements
of the Company during the past two years was unqualified. During the Company's
two most recent fiscal years and the subsequent interim period from the date of
the last audited financial statement through July 19, 1995, there were no
disagreements with Coopers & Lybrand L.L.P. on any matter of accounting
principles or practices, financial statement disclosure, audit scope or
procedures.

                                    BUSINESS
 
     The Company is a leading designer, manufacturer and marketer of vehicle
security systems including alarm and remote keyless entry systems. The Company's
products are marketed and sold through automobile dealerships, independent
retail specialty stores, automotive expediters and mass merchandisers. The
Company believes that it has growth opportunities as a niche supplier to U.S.
and international OEM markets and to its existing customer base.
 
MARKET DESCRIPTION AND INDUSTRY OVERVIEW
 
     Theft of vehicles and vehicle contents is a widespread problem in the U.S.
and most European countries. According to industry sources, in the United
States, the theft of vehicles and vehicle contents, including repair and
replacement costs, recovery costs, loss of productivity, etc., resulted in
losses of approximately $7.5 billion in 1994 and the car theft rate in Germany,
France and other affluent Western European countries was 13 per 1,000 vehicles,
compared to 8 per 1,000 in the United States.
 
     Traditionally, vehicle security systems have been sold mainly in the
aftermarket. However, automakers are beginning to offer vehicle security systems
as installed options, either at the factory or at the dealership. Although most
anti-theft devices are not offered as standard equipment on vehicles, the
Company believes that the general trend is toward vehicle security systems that
are either OEM-approved or installed on the assembly line.
 
     The Company also believes that demand by European consumers for anti-theft
devices is stimulated by rising insurance premiums and incentives offered by
some European insurance companies for using vehicle security systems. These
incentives are typically in the form of lower premiums for suitably equipped
cars and lower claim payouts for those that are not. In certain European
countries, automobiles above a specific monetary value cannot be insured against
theft without an approved anti-theft system installed.
 
     The Company believes that the foregoing factors will continue to increase
both domestic and European demand for vehicle security systems and that it is in
the process of effectively positioning itself to take advantage of these growing
global markets for vehicle security systems.
 
BUSINESS STRATEGY
 
     Key elements of the Company's business strategy include the following:
 
     - Focus Sales Efforts to OEM customers.
 
     The Company intends to focus its sales and marketing efforts toward the OEM
market primarily through the following:
 
          Auto Brand Distribution to Dealers -- The Company presently markets
     its products to more than 9,000 automobile dealers in North America
     pursuant to private label purchase agreements with General Motors, Ford and
     Chrysler under the automakers' brand names including Mr. Goodwrench(TM),
     Ford Remote Systems(TM) and Mopar(TM), respectively, and it believes that
     additional growth opportunities are available through such dealers. The
     Company expects to pursue these opportunities by continuing to promote its
     sales to dealers through personal calls on dealers by the Company's sales
     staff, dealer education programs, seminars, product literature and manuals
     and on-site promotional items such as signs. To support such sales efforts,
     the Company intends to continue to offer technical support service and
     toll-free telephone lines to answer questions and help with problems.
 
          Direct Sales to Manufacturers for Factory Floor Installation -- The
     Company believes that there is potential for expanding its sales to OEMs
     for such items as remote keyless entry systems, basic alarm systems and
     sensors. In light of increased consumer demand for systems offered in
     top-of-the-line models, OEMs are increasingly offering such systems. It is
     the Company's intent to capture a larger share of this market, which is
     currently supplied by more traditional OEM electronic suppliers such as
     TRW, Motorola and United Technologies. The Company's efforts in this regard
     currently consist of direct sales calls to automobile manufacturers by the
     Company's sales personnel and independent manufacturers representatives,
     and are focused on obtaining long-term supply contracts.

          Strategic Alliances -- The Company is exploring opportunities to enter
     into strategic relationships with other suppliers to deliver to the OEMs a
     product which incorporates the Company's systems or technologies. For
     example, the Company has recently entered into development projects with
     both Lear Seating Corp. and Gentex Corp. to supply parts to these two
     manufacturers for use in their end products sold to OEMs. The Company
     believes that the multiplexing systems (which consist of a sophisticated
     computer processor located in the vehicle, connected to various electrical
     systems of the vehicle by a single wire, which allows simultaneous
     communication between multiple vehicle systems) now being employed by
     automakers offer a particular opportunity for such strategic alliances. See
     "Business Strategy-Enhanced Engineering Capability" and "Engineering,
     Research and Development."
 
     - Continue Sales to Post-Delivery Market
 
     Historically, the Company has successfully marketed to independent
retailers and mass merchandisers. Currently, the Company sells to more than
1,200 independent retail specialty stores; automotive expediters; and mass
merchandisers. The Company intends to continue its focus on this market.
 
     - Expand European Presence
 
     The Company believes that it has significant growth opportunities both in
the OEM and retail markets in Europe. Recognizing this, the Company acquired EAE
as of January 1, 1994. The Company is currently concentrating its European sales
efforts in France. Further expansion into other European markets is complicated
by certain factors such as government approvals and insurance industry
accreditation required to sell its products. In certain European countries,
insurance industry certification of a vehicle security system is a prerequisite
to obtaining theft insurance for most motor vehicles. The Company has received
French and Belgian insurance industry accreditation for its electronic security
systems, but to date has been unable to secure German insurance industry
accreditation required to sell its products in Germany. European insurance
industry standards are subject to change without notice; and, in 1994,
significant changes in industry standards required the development and
introduction of new products for 1995. The Company is currently seeking
accreditation in several major European countries in an effort to take advantage
of the growing market for vehicle security systems.
 
     - Enhance Engineering Capability
 
     In order to stay competitive and deliver high quality, consumer-friendly
vehicle security systems, the Company plans to continue to enhance its
engineering and product testing capabilities. The Company believes that
multiplexing systems planned for some top-of-the-line automobiles will allow
more efficient access to a larger number of vehicle operations than present
conventional wire harness electrical systems, and that the presence of these
multiplexing systems will present potential growth opportunities for the Company
over the next decade. The Company believes that it is favorably positioned to
increase its business opportunities for interfacing with multiplexing systems
because of the Company's reputation for technical innovation, quality,
reliability and competitive pricing. See "Engineering, Research and
Development."
 
     - Shorten Product Development and Introduction Cycles
 
     The Company believes that short product development cycles are essential to
its success. Such cycles enable the Company to capitalize upon the higher
margins that are associated with the introduction of new products and positions
the Company to establish itself as a leader in its existing as well as its new
markets. The Company's efforts in this area include simultaneous engineering
which utilizes product teams from the engineering and manufacturing divisions of
the Company whose function is to streamline product development and introduction
cycles.
 
PRODUCTS
 
     The Company's vehicle security systems utilize low power radio frequency
technology and are operated by remote micro-transmitters. Frequencies and the
manufacture of transmitters and receivers used in the Company's remote systems
are different in European countries than in the U.S. and are regulated
separately in each country in which the Company does business.
 
                                       17
<PAGE>   23
 
     The Company's vehicle security systems fall into two broad categories:
alarm systems and remote keyless entry systems.
 
     Alarm Systems -- In general, the Company's alarm systems contain two major
components: an immobilizer circuit and a siren. The immobilizer circuit prevents
the automobile from being started unless the alarm system has been turned off.
Each system automatically resets itself after the siren has been sounded for a
predetermined period. Many of these systems allow the operator to choose between
manually setting the alarm upon leaving the vehicle and having the alarm
automatically set one minute after the keys are removed from the ignition
switch. Various other components, such as hood locks and intrusion sensors, can
generally be added to the alarm system.
 
     Historically, most of the Company's sales have consisted of remote alarm
systems, with a basic unit consisting of a remote micro-transmitter, which can
be attached to the operator's keychain, and a control unit, which is located
inside the automobile. The remote micro-transmitter is used to turn the alarm
system on and off. This basic unit is typically sold as part of a system which
is configured in various ways based upon the customer preferences and
distribution channels.
 
     In addition to remote alarm systems, the Company also produces digital and
passive alarm systems which offer a lower level of protection. Digital systems,
unlike remote systems, do not offer a way to turn the alarm system on and off
from outside the vehicle. Instead, upon entering the vehicle, the operator has a
fixed period of time to turn off the alarm system by entering the proper
numerical sequence on a keypad. Passive alarm systems are much like digital
systems, except that the operator only needs to insert the key in the ignition
switch of the automobile to turn off the alarm.
 
     Remote Keyless Entry Systems -- The Company's remote keyless entry system
enables the operator to use the remote micro-transmitter to lock and unlock the
doors or open the trunk from outside the vehicle without having to use keys, to
turn on the interior light to see if anyone is waiting inside the vehicle and to
set off the siren in the event of a personal emergency.
 
     The Company's vehicle security systems, most of which are now remote
systems, include Code-Alarm(R), Scorpion(R), Chapman(R) and Anes(R) brands in
the U.S. and Dragon, Jack-Code, Codalarme(R) and Euro-Alarm in Europe.
 
     The Company's products are sold into two categories: pre-delivery and
post-delivery. Pre-delivery includes those products sold in the OEM market for
vehicle installation before delivery of a new vehicle to the purchaser (either
through installation by the automaker or as a dealer-installed option or by an
automotive expediter). Post-delivery includes those products which are installed
on a vehicle already owned by the customer (generally through retail specialty
stores and mass merchandisers).

     With the exception of sales to dealers of General Motors and Ford, no
single customer accounted for more than 10% of the Company's total net sales
during the year ended December 31, 1994. Sales to Ford, General Motors and
Peugeot accounted for 10.9%, 10.8% and 7.1%, respectively, of the Company's
total net sales for the year ended December 31, 1994. Pursuant to its agreements
with General Motors and Ford, the Company's direct sales personnel and
independent manufacturer's representatives engaged by the Company call on, and
solicit orders directly from, General Motors and Ford dealers. The Company views
individual dealers as its customers.
 
     The Company historically has placed and expects to continue to place a
strong emphasis on its retail customers. The Company believes that accelerated
growth in the OEM market for vehicle security systems offers the Company an
opportunity to increase future sales and, therefore, its expansion into the OEM
market, as well as its continued presence in the retail market, is important to
the Company's future success. The increase in pre-delivery installation could
have a detrimental effect on the retail market.
 
     The following table shows the percentage of the Company's total net sales

MARKETING
 
     Sales of the Company's products to OEMs are made directly by the Company's
sales and marketing personnel located at the Company's Madison Heights, Michigan
headquarters and its European offices located in Paris, Brussels, Madrid and
Birmingham, England. Through these sales and marketing offices, the Company
services its OEM customers. These sales efforts are supported by a field force
of 62 salespersons
 
                                       19
<PAGE>   25
 
who call directly on dealers to explain and promote the ordering of the
Company's products through the OEMs.
 
     In promoting sales of vehicle security systems that require professional
installation, the Company emphasizes dealer education programs, sales and
installation seminars, product literature and technical manuals. Educational and
marketing efforts are supplemented by direct mail campaigns, technical
bulletins, advertising support, sales literature, newsletters, product displays
and dealer signs.
 
     To promote quality, customer satisfaction and relationships with dealers
and installers, the Company maintains technical support and consumer support
services and toll-free telephone lines to answer questions and to help solve
problems with installation or operation of the Company's products.
 
ENGINEERING, RESEARCH AND DEVELOPMENT
 
     The Company employs 20 full-time engineers and 31 full-time technicians in
its engineering and research and development programs. This staff is divided
into three main groups responsible for: (a) providing technical and support
services to its customers, (b) improving manufacturing processes, and (c)
developing new products. The Company's expenditures for engineering, research
and development were approximately 3.5%, 3.4% and 3.7% of revenues in 1992, 1993
and 1994, respectively.
 
     The Company conducts a variety of research and product development projects
designed to achieve improvements in vehicle security systems through the
development of new technologies. The Company's products include a number of
innovative circuits and features developed by the Company. Past research and
development efforts have produced consumer installable vehicle security systems
that incorporate many of the features typically found on more expensive
professionally-installed systems, as well as the circuitry designed to prevent
use of devices designed to search signals to deactivate its alarms.
 
     The technological innovations of the Company's customers presents both
challenges and opportunities for the Company. The Company's products must be
advanced enough to efficiently interface with its customer's vehicles. One new
innovation which has recently been introduced on certain high-end vehicles is
the multiplexing system. The multiplexing system consists of a sophisticated
computer processor located in the vehicle, connected to various electrical
systems of the vehicle by a single wire, which allows simultaneous communication
between multiple vehicle systems. As a result, the vehicle can accommodate more
sophisticated operations and technologically complex accessories such as
security systems. Multiplexing systems allow security systems more efficient
access to a larger number of vehicle operations than do conventional wire
harness electrical systems. The Company believes that the presence of
multiplexing systems present potential growth opportunities for the Company over
the next decade. The Company believes that it is positioned to increase its
business opportunities for connecting its products to the multiplexing systems
because of the Company's reputation for technical innovation, quality,
reliability and competitive pricing.
 
MANUFACTURING
 
     The Company produces electronic products at facilities located in Madison
Heights, Michigan and Georgetown, Texas. Automated and manual assembly methods
are used to produce circuit boards, which are key components of many of the
Company's products. The Company is expanding the use of automation in its
manufacturing operations. The Company's electronic security systems are designed
around the Company's manufacturing processes, which particularly emphasize
surface mount technology ("SMT"). SMT is the automated manufacturing process
used to place micro electronic components on printed circuit boards with a high
level of accuracy and at high speed. The use of SMT enables the Company to
design and manufacture products that are compact, portable and reliable and to
achieve manufacturing efficiencies that result in lower costs.
 
     The Company believes that it will have a competitive advantage as a result
of its recent development and on-going construction of an on-premises test and
validation laboratory and its lower labor costs for U.S. operations. In
addition, the Company is in the process of seeking approval for QS 9000
accreditation and
 
                                       20
<PAGE>   26
 
hopes to obtain such accreditation during 1996, which, if granted, could result
in an additional competitive advantage.
 
     While the Company currently does not manufacture its products in Europe,
the Company does assemble some of its final products in Europe. At this time the
Company is considering various alternatives for manufacturing its products
overseas.
 
     The Company attempts to fill its U.S. orders for vehicle security systems
within 48 hours. Current U.S. product backlog, therefore, is not an important
indicator of long-term sales trends. However, since European operations are
currently supplied from U.S. manufacturing plants, additional inventory
requirements necessary to achieve the 48-hour shipment goal have significantly
increased working capital requirements and management attention to order and
production planning.
 
SUPPLIERS
 
     The Company's products include a number of high-technology components that
are available from only a few suppliers and, in some cases, a single supplier.
The Company frequently requires large volumes of such components. If the
Company's suppliers are unable to fulfill the Company's needs for such
components, the Company may be unable to fill customer orders and its business
and financial condition, including working capital and results of operations,
may be materially and adversely affected. Since part of the Company's strategy
is to shorten product development and introduction cycles, occasions may arise
in the future where the Company's ability to produce products outpaces its
suppliers' ability to supply components. There can be no assurance that the
Company can continue to obtain adequate supplies or obtain such supplies at
their historical cost levels. The Company has no guaranteed supply arrangements
with any of its sole or limited source suppliers, does not maintain an extensive
inventory of components, and customarily purchases sole or limited source
components pursuant to purchase orders placed in the ordinary course of
business. Moreover, the Company's suppliers may, from time to time, experience
production shortfalls or interruptions which impair the supply of components to
the Company. There can be no assurance that such shortages will not occur in the
future and adversely affect the Company's business and financial condition,
including working capital, and results of operations. See "Risk Factors --
Suppliers."
 
PRODUCT WARRANTY
 
     The Company provides original purchasers of most vehicle security systems
with a limited warranty. Scorpion(R) brand products have a one-year limited
warranty and Anes(R) brand carries a limited two-year warranty. Dragon,
Jack-Code and Codalarme(R) products sold in Europe have a limited one-year
repair and replacement warranty. Warranties are customarily limited to
replacement of defective parts to the original purchaser. The Company has
several disputes pending with customers who claim that its home security and
Intercept(TM) systems manufactured by the Company were faulty or inoperable.
 
     The Company also offers a "Theft Protection Guarantee" for certain
Code-Alarm(R) and Anes(R) brand products, where the Company will pay the
consumer a specified amount (depending on the product purchased) if the
consumer's vehicle is stolen within one year of purchasing the Company's
product. Claims experienced as to this warranty have been $37,000, $33,000,
$51,000 in 1992, 1993 and 1994, respectively, and $19,000 for the first nine
months of 1995.
 
     The Company generally warrants contract manufactured products for 60 days.
The warranty is limited to replacement of defective material or a price
allowance at the Company's option.
 
COMPETITION
 
     All markets in which the Company participates are highly competitive, and
many current or prospective competitors, including several of the Company's
significant OEM customers, are substantially larger and possess significantly
greater financial, marketing and technical resources than the Company. An
increase in factory-installed vehicle security systems or the introduction of
other dealer-installed security systems and
 
                                       21
<PAGE>   27
 
remote keyless entry systems by OEM customers or existing and potential
competitors could have a material adverse effect on the Company. See "Risk
Factors -- Competition."
 
     There are a number of other well-known companies manufacturing and
distributing electronic components for the automotive after-market which could
become effective competitors should they choose to enter the vehicle security
market. Many of these companies are much larger and better capitalized than the
Company and have established distribution channels. While offshore producers of
competing systems have not captured significant market share, these companies
could also become significant competitors.
 
     Competing manufacturers have developed vehicle recovery systems designed to
locate stolen automobiles. Sales of other companies' automobile recovery systems
could have a material adverse effect on sales of the Company's products. The
Company also faces competition from certain mechanical devices such as The
Club(TM).
 
TRADEMARKS AND PATENTS
 
     The Company markets its vehicle security systems under several registered
trademarks. The Company also has patents and patent applications pending for
certain of its products and components. The Company considers its trademarks,
patents and patent applications to be valuable, and has defended, and intends to
continue vigorously defending, its patented and proprietary technology from
infringement or misappropriation. There can be no assurance that the Company's
measures to protect its proprietary rights will deter or prevent unauthorized
use of the Company's technology. Furthermore, the laws of certain countries may
not protect the Company's proprietary rights to the same extent as do the laws
of the United States. The Company has applied for patents on certain inventions
in Europe; however, none of these patents has yet been granted nor is there any
assurance that patents will be granted in the future. In addition, the Company
may, from time to time, become subject to legal claims asserting that the
Company has violated intellectual property rights of third parties. In the event
a third party were to sustain a valid claim against the Company and in the event
any required license were not available on commercially reasonable terms, the
Company's business and financial condition, including working capital and
results of operations, could be materially and adversely affected. See "Risk
Factors -- Intellectual Property." Also, see "Legal Proceedings" for a more
complete description of the legal proceedings involving the Company and its
proprietary technology.
 
REGULATION
 
     The FCC regulates the assignment of frequencies for manufacture and sale of
remote vehicle security systems and remote keyless entry systems in the U.S. The
Company has received FCC authorization to manufacture and sell the devices it
currently sells in the U.S.  In Europe, similar government agencies in each
country regulate the assignment of frequencies and the Company has generally
been able to meet the applicable frequency requirements. However, because
insurance industry accreditation of vehicle security systems is, in most
European countries, a prerequisite to an automobile owner's ability to obtain
vehicle theft coverage, the Company's ability to market its products in such
countries is dependent upon obtaining such insurance industry approvals and
certifications. The Company has received French and Belgian insurance industry
accreditation to manufacture and sell electronic security systems. To date, the
Company has been unable to secure German insurance industry accreditation
required to sell its products in Germany. The Company is selling its products in
Spain where no insurance industry certifications are required. European
insurance industry accreditation standards are subject to change without notice;
and, in 1994, significant changes in industry standards required the development
and introduction of new products for 1995.
 
     The Company's U.S. vehicle security systems are also affected by state
insurance laws. The Company is aware of some states that mandate insurance
discounts on comprehensive coverage for policyholders who have installed certain
types of vehicle security systems. The Company is also aware of at least one
state which provides additional discounts for policyholders who have installed
vehicle recovery systems.
 
     The loss of regulatory and insurance industry approvals or failure to
obtain necessary authorizations in the future could have a material adverse
effect on the Company. See "Risk Factors -- Regulation."

EMPLOYEES
 
     As of October 30, 1995, the Company employed approximately 550 full-time
persons. None of the Company's employees are represented by a labor union or
other collective bargaining representative. The Company believes that relations
with its employees are good.

                               LEGAL PROCEEDINGS
 
PATENT INFRINGEMENT LITIGATION
 
     In November 1987, the Company filed a declaratory judgment action against
Electromotive Technology Corporation ("ETC") in the United States District Court
for the Eastern District of Michigan seeking a declaration that ETC's U.S.
Patent No. 4,585,569 (the " '569 Patent") was invalid or not infringed by the
Company. Subsequently, Directed Electronics ("Directed") acquired an interest in
the '569 Patent and was made a party to the lawsuit. A judgment as to liability
was entered against the Company in 1992 and, after that judgment was sustained
on appeal, a bench trial was held as to damages in 1993, but no final ruling was
made until May 23, 1995, when a judgment was awarded against the Company in the
amount of $5.5 million for infringement. The Company is now appealing (1) the
inclusion of unpatented components of the Company's security system in the
damage calculation and (2) the doubling of "actual damages" after November, 1990
based upon a holding of "willful patent infringement." In the course of
preparing the appeal brief, it was discovered that ETC had failed to timely pay
the first maintenance fee in April, 1990 to maintain the patent-in-suit with the
U.S. Patent and Trademark Office (the "Patent Office"). The Company subsequently
filed a motion with the United States District Court for the Eastern District of
Michigan, Southern Division requesting certification for remand of the case for
consideration of (1) the Company's intervening rights for the ten month lapse in
the patent-in-suit, (2) reconsideration of the award of enhanced damages and
attorney fees in view of ETC's failure to notify the Company and the court of
the lapse, and (3) an appeal of the Patent Office's decision to reinstate the
patent-in-suit. This motion was denied without prejudice by the United States
District Court and the Company is preparing to file motions with the Court of
Appeals for the Federal Circuit for remand or dismissal of the appeal based upon
lack of jurisdiction for consideration by the District Court of the motion. Both
ETC and Directed are asserting patent infringement
 
                                       23
<PAGE>   29
 
claims against two other shock sensor embodiments, one of which is the Company's
principal shock sensor unit.
 
     The Company has posted a letter of credit in lieu of an appeal bond in the
amount of $5.9 million, representing the amount of the judgment, including
interest.
 
LITIGATION INVOLVING ACQUISITIONS
 
     On January 19, 1990, Chapman Security Systems, Inc. ("Chapman Security"), a
wholly-owned subsidiary of the Company, purchased certain of the assets of
Chapman Products, Inc. ("Chapman Products") from LaSalle National Bank in a
private sale in accordance with Section 9-504 of the Illinois Uniform Commercial
Code. On August 17, 1990, Aureo Rivera Davila and Aureo E. Rivera ("Plaintiffs")
filed a complaint against Asset Conservation, Inc. (a distributor of the now
defunct Chapman Industries Corporation ("Chapman Industries")), Gabriel Guijarro
Brunet and Iris Nieves De Guijarro and their marital conjugalship, in the United
States District Court for the District of Puerto Rico (Case No. 90-2118 (SEC))
alleging infringement of United States Patent No. 3,548,373 (the " '373
Patent"). Asset Conservation filed a third-party complaint in the same court on
June 16, 1992 against Chapman Industries, Chapman Products, the Company and
Chapman Security alleging that they have a duty to indemnify Asset Conservation
for all damages sustained by it in the litigation based upon Asset
Conservation's previous distributor and indemnification agreement with Chapman
Industries, which Asset Conservation claims was assumed by Chapman Products and
Chapman Security. Plaintiffs have a default judgment in the amount of about
$19.3 million, in addition to interest, entered by the United States District
Court for the Northern District of Illinois in 1990 against Chapman Industries
Corporation for infringement of the '373 Patent. Subsequently, the Plaintiffs
added Chapman Products, the Company and its subsidiary, Chapman Security, as
principal defendants in the case and are attempting to assert their default
judgment against the Company and Chapman Security on a theory that the Company
is the sole owner of Chapman Security and operates Chapman Security as its alter
ego and, therefore, that the Company is a successor in interest to Chapman
Industries. Plaintiffs also allege that the asset purchases by Chapman Products
and then by Chapman Security were fraudulent conveyances. The Company believes
that the allegations asserted by Asset Conservation and the plaintiffs are
unlikely to succeed. The Company has tendered defense of the complaint to
LaSalle National Bank, which is defending the fraudulent conveyance claims as
well as certain of the successor liability claims brought by Plaintiffs under a
reservation of rights against the Company and Chapman Security. This proceeding
is in the early stages of discovery, and is not likely to be resolved in the
near future. The size of this judgment (which, with interest, is currently
estimated to be approximately $28.6 million, is so large that if it is enforced
against the Company and Chapman Security, the likely award would exceed the
Company's shareholders' equity, in which case the purchasers of the Debentures
could lose their entire investment.
 
     M. and Mme. Sydney Drahy, from whom the Company purchased shares of its
French subsidiary EAE, filed suit against the Company in the Commercial Court in
Paris, France on August 1, 1995, seeking FF3,160,000 (approximately $645,000)
based on disputed price adjustment provisions in the purchase agreement. The
Company believes that there are offsets to the disputed adjustments under the
purchase agreement, some of which have been acknowledged by the Drahys, and that
no additional amounts are owed the Drahys in respect of the purchase price. A
decision on this case is not expected to be rendered before mid-1996. Mme. Drahy
brought a separate action in the Industrial Court of Paris against EAE, filed
June 20, 1995, seeking damages of FF1,268,800 (approximately $260,000) for
alleged wrongful termination of her employment and breach of an employment
contract. The case is in the early stages of document production and the Company
is unable at this time to assess its exposure, if any, to Mme. Drahy.
 
PRODUCT WARRANTY LITIGATION
 
     On July 19, 1995, Intercept Security Corporation, a Canadian distributor of
the Company's home security systems ("Intercept"), filed suit in the United
States District Court, Eastern District of Michigan, Southern Division, alleging
that certain home security products manufactured and sold by the Company failed
to perform in a manner consistent with the alleged representations of the
Company. The complaint alleges that the Company committed fraud,
misrepresentation, and breached an implied warranty emanating from the sale
 
                                       24
<PAGE>   30
 
of these goods to Intercept. The Company denies these allegations and intends to
defend against these charges. The Company has not, as yet, answered the
complaint and the case remains in the early stages of discovery. The exposure,
if any, to the Company cannot be ascertained at this time; however, an adverse
judgment could materially adversely affect the Company's business and financial
condition, including working capital and results of operations.
 
LITIGATION COMMENCED BY THE COMPANY AGAINST ALLEGED PATENT INFRINGERS
 
     During 1995, the Company brought the following actions seeking to enforce
its patents against alleged infringers. All of these lawsuits are in various
stages of discovery and are subject to various affirmative defenses and
counterclaims. While the Company believes that these actions are meritorious,
the outcomes cannot be predicted at this early stage. It is the Company's policy
to pursue infringers of its patents vigorously in an effort to preclude the
manufacture and sale of infringing inventions or, alternatively, to seek payment
of royalties on the Company's patented inventions manufactured, sold or used by
others.
 
          - Code-Alarm, Inc. v. Magnadyne Corporations, et al, filed March 21,
     1995 in the United States District Court for the District of Columbia and
     Transferred on April 6, 1995 to the United States District Court for the
     Central District of California sitting in Los Angeles, California.
 
          - Code-Alarm, Inc. v. Sherwood, Inc. et al, filed on July 20, 1995 in
     the United States District Court for the Central District of California
     sitting in Los Angeles, California.
 
          - Code-Alarm, Inc. v. Clifford Electronics, Inc., filed October 12,
     1995 in the United States District Court for the Central District of
     California sitting in Los Angeles, California.
 
          - In the matter of Certain Starter Kill Security Systems, filed
     October 18, 1995 with the International Trade Commission against Directed
     Electronics, Inc. of Vista, California and Nutek Company of Taipei, Taiwan.
     In addition to claims of patent infringement, the Company seeks in this
     action to halt the importation and sale of the alleged infringing goods
     into the United States.

amount ($11,500,000 if the Underwriters' over-allotment option is exercised in
full), will be issued in fully registered form only in denominations of $1,000
or any integral multiple thereof and will mature on December 1, 2002.
 
     The following statements are subject to the detailed provisions of the
Indenture and are qualified in their entirety by reference to the Indenture, a
copy of which is filed as an exhibit to the Registration Statement (as defined)
and is also available for inspection at the office of the Trustee. Whenever
particular provisions of the
 
                                       27
<PAGE>   33
 
Indenture are referred to, such provisions are incorporated by reference as a
part of the statements made herein, and the statements are qualified in their
entirety by such reference.
 
     Interest at the annual rate set forth on the cover page hereof is payable
semi-annually on June 1 and December 1, commencing on June 1, 1996, to holders
of record at the close of business on the preceding November 15 and May 15,
respectively. Interest on the Debentures offered hereby will accrue from the
date of initial issuance.
 
     Principal and premium, if any, and interest will be paid and the Debentures
may be presented for conversion, registration of transfer, and exchange, without
service charge, at the corporate trust office of the Trustee in Boston,
Massachusetts. Interest will be paid by checks mailed to holders of record
unless other arrangements are made.
 
CONVERSION OF DEBENTURES
 
     The holders of Debentures will be entitled at any time prior to the close
of business on December 1, 2002, subject to prior redemption, to convert the
Debentures or portions thereof (which are $1,000 or integral multiples thereof)
into shares of Common Stock of the Company, at the conversion price set forth on
the cover page of this Prospectus, subject to adjustment as described below.
Except as described below, no adjustment will be made on conversion of any
Debenture for interest accrued thereon or for dividends on any shares of Common
Stock issued. If any Debenture not called for redemption is converted between a
record date for the payment of interest and the related interest payment date,
the Debenture must be accompanied by funds equal to the interest payable on such
interest payment date on the principal amount so converted. The Company is not
permitted to issue fractional shares of Common Stock upon conversion of
Debentures and, in lieu thereof, will pay a cash adjustment based upon the
market price of the Common Stock on the last trading day prior to the date of
conversion. In the case of Debentures called for redemption, conversion rights
will expire at the close of business on the redemption date. Persons who may be
deemed to be affiliates of the Company for purposes of the Securities Act of
1933 may be subject, as to any resales of shares of Common Stock acquired on
conversion, to the restrictions of Rule 144 promulgated under the Act.
 
     The conversion price is subject to adjustment under formulas set forth in
the Indenture in certain events, including: the issuance of shares of Common
Stock of the Company as a dividend or distribution on the Common Stock;
subdivisions, combinations, and reclassifications of the Common Stock; the
issuance to all holders of Common Stock of certain rights or warrants entitling
them for a period not exceeding 45 days to subscribe for Common Stock at less
than the then current market price (as defined); and the distribution to all
holders of Common Stock of any securities (other than Common Stock) or evidences
of indebtedness of the Company or of assets (excluding cash dividends or
distributions from retained earnings) or rights or warrants to subscribe for or
purchase any of its securities (excluding those referred to above). No
adjustment in the conversion price will be required unless such adjustment would
require a change of at least 1% in the conversion price then in effect;
provided, however, that any adjustment that would otherwise be required to be
made shall be carried forward and taken into account in any subsequent
adjustment. The Company reserves the right to make such reductions in the
conversion price, in addition to those required by the foregoing provisions, as
the Company in its discretion shall determine to be advisable in order that
certain share-related distributions made by the Company to its shareholders
after the date of this Prospectus will not be taxable. Except as stated above,
the conversion price will not be adjusted for the issuance of shares of Common
Stock or any securities convertible into or exchangeable for Common Stock, or
carrying the right to purchase any of the foregoing, in exchange for cash,
property, or services.
 
     In the case of a consolidation, merger or statutory share exchange
involving the Company as a result of which holders of Common Stock will be
entitled to receive stock, securities or other property or assets (including
cash) with respect to or in exchange for shares of Common Stock or in the case
of a sale or conveyance to another corporation of all or substantially all the
property and assets of the Company, the holders of the Debentures then
outstanding will be entitled thereafter to convert such Debentures into the kind
and amount of shares of stock, other securities or other property or assets
which they would have owned or been entitled to receive upon such consolidation,
merger, statutory share exchange, sale or conveyance had
 
                                       28
<PAGE>   34
 
such Debentures been converted into shares of Common Stock immediately prior to
such consolidation, merger, statutory share exchange, sale or conveyance.
 
     In the event of a taxable distribution to holders of Common Stock which
results in an adjustment of the conversion price, the holders of Debentures may,
in certain circumstances, be deemed to have received a distribution subject to
United States income tax as a dividend; the absence of such an adjustment in
certain other circumstances may also result in a taxable dividend to the holders
of Common Stock.
 
OPTIONAL REDEMPTION
 
     The Debentures will be redeemable on at least 45 and not more than 60 days'
notice, at the option of the Company, as a whole or in part, at any time after
issuance, at the following prices (expressed as percentages of the principal
amount), together with accrued interest to the date fixed for redemption:
 
     If redeemed during the 12-month period beginning December 1:

and 100% if redeemed on or after December 1, 2002; provided, however, that the
Debentures may not be redeemed prior to December 1, 1998, unless the last
reported sales price (determined as provided in the Indenture) of the Common
Stock equals or exceeds 140% of the then effective conversion price (as
described above) for at least 20 trading days within a period of 30 consecutive
trading days ending no earlier than ten trading days prior to the date of the
notice of redemption.
 
SUBORDINATION OF DEBENTURES
 
     The indebtedness evidenced by the Debentures is subordinate to the prior
payment in full of all Senior Indebtedness (as defined). During the continuance
beyond any applicable grace period of any default in the payment of principal,
interest or lease payments on any Senior Indebtedness, no payment of principal
of, premium, if any, or interest on the Debentures shall be made by the Company.
In addition, upon any distribution of assets of the Company upon any
dissolution, winding up, liquidation or reorganization, the payment of the
principal of, premium, if any, and interest on the Debentures is to be
subordinated to the extent provided in the Indenture in right of payment to the
prior payment in full of all Senior Indebtedness. By reason of such
subordination, in the event of the Company's dissolution, holders of Senior
Indebtedness may receive more, ratably, and holders of the Debentures may
receive less, ratably, than the other creditors of the Company or may receive no
consideration at all. Such subordination will not prevent the occurrence of any
Event of Default under the Indenture.
 
     The term "Senior Indebtedness" is defined to mean the following, whether
outstanding on the date of execution of the Indenture or thereafter created,
incurred, assumed or guaranteed:
 
          (a) Principal of and premium, if any, and interest on indebtedness of
     the Company for money borrowed (including any indebtedness secured by a
     mortgage or other lien which is (i) given to secure all or part of the
     purchase price of property subject thereof, whether given to the vendor of
     such property or to another, or (ii) existing on property at the time of
     the acquisition thereof) evidenced by notes or other written obligations;
 
          (b) Principal of and premium, if any, and interest on indebtedness of
     the Company evidenced by notes, debentures, bonds or other securities of
     the Company;
 
          (c) The amount of the Company's liability determined under generally
     accepted accounting principles under any lease required to be classified as
     a liability on the Company's balance sheet;
 
                                       29
<PAGE>   35
 
          (d) Principal of and premium, if any, and interest on indebtedness of
     others of the kinds described in either of the preceding clauses (a) or
     (b), or, to the extent set forth in the preceding clause (c), leases of
     others of the kind described in the preceding clause (c) assumed by or
     guaranteed in any manner by the Company or in effect guaranteed by the
     Company through an agreement to purchase, contingent or otherwise; and
 
          (e) Principal of and premium, if any, and interest on renewals,
     extensions, or refundings of indebtedness of the kinds described in any of
     the preceding clauses (a), (b) or (d) or, to the extent set forth in the
     preceding clause (c), renewals or extensions of leases of the kinds
     described in either of the preceding clauses (c) or (d).
 
unless, in the case of any particular indebtedness, lease, renewal, extension,
or refunding, the instrument or lease creating or evidencing the same or the
assumption or guarantee of the same expressly provides that such indebtedness,
lease, renewal, extension, or refunding is not superior in right of payment to
the Debentures.
 
     As of October 26, 1995, the Company had approximately $18.3 million of
Senior Indebtedness, including security for a $5.9 million letter of credit for
a litigation appeal bond, (approximately $9.3 million after giving effect to the
application of the net proceeds of this Offering).
 
     The Indenture permits the Trustee to become a creditor of the Company and
does not preclude the Trustee from enforcing its rights as a creditor, including
rights as a holder of Senior Indebtedness.
 
REPURCHASE EVENT
 
     Upon the occurrence of a Repurchase Event, each holder of Debentures shall
have the right to require the Company to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of such holder's Debentures pursuant to
the offer described below (the "Repurchase Offer") at a purchase price equal to
101% of the aggregate principal amount thereof plus accrued and unpaid interest,
if any, to the date of purchase (the "Repurchase Payment"). Within 30 days after
the occurrence of a Repurchase Event, the Company shall mail a notice to each
holder stating among other things: (a) the Repurchase Payment and the purchase
date, which shall not be earlier than 45 days nor later than 60 days from the
date such notice is mailed or such later date as may be necessary for the
Company to comply with the requirements of the 1934 Act (the "Repurchase Date");
(b) that any Debenture not tendered will continue to accrue interest; (c) that,
unless the Company defaults in the payment of the Repurchase Payment, all
Debentures accepted for payment pursuant to the Repurchase Offer shall cease to
accrue interest after the Repurchase Date; and (d) certain other procedures that
a holder must follow to accept a Repurchase Offer or to withdraw such
acceptance. The Company will comply with any applicable requirements of the 1934
Act and other securities laws, and the regulations thereunder, governing the
repurchase of the Debentures in connection with a Repurchase Event and may
modify a Repurchase Offer to effect such compliance.
 
     A Repurchase Event is generally defined to include (a) the acquisition of
50% or more of the Company's voting stock by a person or group, other than any
current holder of 5% or more of the Company's Common Stock (or a group including
such a holder); (b) a change, over a two-year period, in the composition of the
Company's Board of Directors such that, with limited exceptions, the Board
members at the beginning of the period no longer constitute a majority of the
Board; (c) certain consolidations and mergers involving the Company or sales of
assets of the Company, if the primary effect is that, after the transaction, a
person or group, other than a current holder of 5% or more of the Company's
Common Stock (or group including such a holder), has more than 50% of the
ordinary voting power of the surviving corporation; (d) the acquisition by the
Company of over 30% of the outstanding shares of its capital stock during any
12-month period; and (e) certain (1) distributions in respect of the Company's
capital stock or (2) acquisitions by the Company of its capital stock, if, in
either case, the sum of the (A) ratio of the fair market value of the price paid
in the current distribution or acquisition to the then-fair market value of the
Company's outstanding capital stock plus (B) the similar ratios for all other
distributions or acquisitions, respectively, during the prior 12-month period,
exceeds 30%. For purposes of the Repurchase Event tests, the Company's "voting
stock" means the Common Stock plus any other class or classes of stock which may
be issued and have general voting power in the election of the Company's Board
of Directors. The Company's "capital stock" means any stock which does
 
                                       30
<PAGE>   36
 
not have divided or liquidation priority over other stock of the Company,
irrespective of relative voting powers. Currently, the Company's only "voting
stock" and "capital stock" is its Common Stock.
 
     On the Repurchase Date, the Company will deposit with the Trustee an amount
equal to the Repurchase Payment in respect of all Debentures or portions thereof
that have been tendered. The Trustee shall promptly mail to each holder of
Debentures accepted for payment an amount equal to the Repurchase Price for such
Debentures, and the Trustee shall promptly authenticate and mail to each holder
a new Debenture equal in principal amount to pay unpurchased portion of the
Debentures surrendered.
 
     Except as described above with respect to a Repurchase Event, the Indenture
does not contain any other provisions that permit the holders of the Debentures
to require that the Company repurchase or redeem the Debentures in the event of
a takeover or similar transaction. The provisions of the Indenture relating to
the purchase of Debentures upon a Repurchase Event may impede the completion of
a merger, tender offer or other takeover attempt. See "Description of Capital
Stock." Neither the Trustee nor the Company's Board of Directors may relieve the
Company of its obligations to repurchase Debentures.
 
     Any future credit agreements or other agreements relating to Senior
Indebtedness to which the Company becomes a party may prohibit the Company from
purchasing any Debentures or may provide that certain change in control events
with respect to the Company would constitute a default under such agreements. In
the event a Repurchase Event occurs at a time when the Company is prohibited
from purchasing Debentures, the Company could seek the consent of its lenders
for the purchase of Debentures or could attempt to refinance the borrowings that
contain such prohibition. If the Company does not obtain such a consent or repay
such borrowings, the Company will remain prohibited from purchasing Debentures.
In such case, the Company's failure to purchase tendered Debentures would
constitute an Event of Default under the Indenture. In such circumstances, the
subordination provisions in the Indenture would restrict payments to the holders
of Debentures.
 
EVENTS OF DEFAULT
 
     An Event of Default is defined in the Indenture as being: default in the
payment of any installment of interest upon any of the Debentures as and when
the same shall become due and payable, and continuance of such default for a
period of 15 days; default in payment of principal or premium, if any, or
interest, if any, on the Debentures when the same becomes due and payable at
maturity, upon redemption or otherwise, whether or not prohibited by the
subordination provisions of the Indenture; default by the Company for 30 days
after notice in the observance or performance of any other covenant in the
Indenture; default under any obligations for money borrowed aggregating
$1,000,000 or more; or certain events involving bankruptcy, insolvency or
reorganization of the Company. The Indenture will provide that the Trustee is
required, within 90 days after the occurrence of a default which is known to the
Trustee and is continuing, to give to the holders of the Debentures notice of
such default; provided that, except in the case of default in the payment of
principal or premium, if any, or interest on any of the Debentures, the Trustee
shall be protected in withholding such notice if it in good faith determines
that the withholding of such notice is in the interest of the holders of the
Debentures.
 
     The Indenture will provide that if any Event of Default shall have occurred
and be continuing, the Trustee or the holders of not less than 25% in principal
amount of the Debentures then outstanding may declare the principal of all the
Debentures to be due and payable immediately, but if the Company shall cure all
defaults (other than the nonpayment of interest and premiums, if any, on and
principal of any Debentures which shall have become due solely by reason of
acceleration) and certain other conditions are met, such declaration may be
annulled and past defaults may be waived by the holders of a majority in
principal amount of the Debentures then outstanding.
 
     The holders of a majority in principal amount of the Debentures then
outstanding will have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee subject to
certain limitations specified in the Indenture.
 
                                       31
<PAGE>   37
 
     In certain cases, the holders of a majority in principal amount of the
outstanding Debentures may on behalf of the holders of all Debentures waive any
past default or Event of Default except, unless theretofore cured, a default in
the payment of the principal of, premium, if any, or interest on any of the
Debentures (other than the nonpayment interest and premium, if any, on and
principal of any Debentures which shall become due by acceleration) or a default
relating to an obligation of the Company which cannot be modified without the
consent of the holder of each Debenture affected.
 
MERGERS AND SALES OF ASSETS BY THE COMPANY
 
     Subject to the provisions described above under "Repurchase Event," the
Company may consolidate with or merge into any other corporation, or sell or
transfer all or substantially all of its assets to any corporation, provided
that the successor corporation shall be a corporation organized and existing
under the laws of the United States or any State thereof and shall assume all of
the obligations of the Company under the Indenture.
 
MODIFICATION OF THE INDENTURE
 
     The Indenture will contain provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
principal amount of the Debentures at the time outstanding, to modify the
Indenture or any supplemental indenture or the rights of the holders of the
Debentures except that no such modification shall, without the consent of the
holder of each Debenture so affected (i) extend the fixed maturity of any
Debenture, reduce the rate or extend the time of payment of interest thereon,
reduce the principal amount thereof or redemption premium thereon, impair or
affect the right of a holder to institute suit for the payment thereof, change
the currency in which the Debentures are payable or impair the right to convert
the Debentures into shares of Common Stock subject to the terms set forth in the
Indenture, or (ii) reduce the aforesaid percentage of Debentures, the consent of
the holders of which is required for any such modification.
 
MISCELLANEOUS
 
     No holder of a Debenture may institute any action against the Company under
the Indenture (except actions for payment of overdue principal, premium, if any,
or interest or the conversion of the Debentures) unless the holders of at least
25% of the principal amount of Debentures then outstanding shall have requested
the Trustee to institute such action, and the Trustee shall not have instituted
such action within 60 days of such request.
 
     A director, officer, employee or shareholder, as such, of the Company shall
not have any liability for any obligations of the Company under the Debentures
or the Indenture, or for any claim based on, in respect of or by reason of, such
obligations or their creation. Each holder of Debentures by accepting a
Debenture waives and releases all such liability. The waiver and release are
part of the consideration for the issuance of the Debentures.
 
     Whether or not required by the rules and regulations of the Commission, so
long as any Debentures are outstanding, the Company will furnish holders of
Debentures all quarterly and annual information that would be required to be
furnished to its shareholders.
 
CONCERNING THE TRUSTEE
 
     State Street Bank and Trust Company, the Trustee under the Indenture, may
at times be a depository for funds of, make loans to or perform services for the
Company and its subsidiaries in the normal course of business. The Indenture
does not preclude the Trustee from enforcing its rights as a creditor, including
rights as a holder of Senior Indebtedness.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The capital stock provisions of the Company's Restated Articles of
Incorporation are summarized below.
 
COMMON STOCK
 
     The Company's Restated Articles of Incorporation authorize 5,000,000 shares
of Common Stock, without par value, of which 2,320,361 shares are expected to be
outstanding upon consummation of the Offering. The existence of authorized but
unissued shares of the Common Stock could discourage unsolicited takeover bids
by third parties.
 
     Except as otherwise required by law or by any amendment to the Restated
Articles of Incorporation, each holder of Common Stock shall have one vote for
each share of stock held of record on the books of the Company on all matters
voted upon by the shareholders.
 
     Subject to the preferential dividend rights, if any, applicable to shares
of Preferred Stock and subject to applicable requirements, if any, with respect
to the setting aside of sums for purchase, retirement or sinking funds for
Preferred Stock, the holders of Common Stock shall be entitled to receive, to
the extent permitted by law, such dividends as may be declared from time to time
by the Board of Directors.
 
     In the event of the voluntary or involuntary liquidation, dissolution,
distribution of assets or winding up of the Company, after distribution in full
of the preferential amounts, if any, to be distributed to the holders of shares
of Preferred Stock, holders of Common Stock shall be entitled to receive all of
the remaining assets of the Company of whatever kind available for distribution
to shareholders ratably in proportion to the number of shares of Common Stock
held by them respectively. The Board of Directors may distribute in kind to the
holders of Common Stock such remaining assets of the Company or may sell,
transfer or otherwise dispose of all or any part of such remaining assets to any
other corporation, trust or entity, or any combination thereof, and may sell all
or any part of the consideration so received and distribute any balance thereof
in kind to holders of Common Stock. The merger or consolidation of the Company
into or with any other corporation, or the merger of any other corporation into
it, or any purchase or redemption of shares of stock of the Company of any
class, shall not be deemed to be a dissolution, liquidation or winding up of the
Company for the purposes of this paragraph.
 
     Such numbers of shares of Common Stock as may from time to time be required
for such purposes shall be reserved for issuance (i) upon conversion of any
shares of Preferred Stock or any obligation of the Company convertible into
shares of Common Stock which is at the time outstanding or issuable upon
exercise of any options or warrants at the time outstanding and (ii) upon
exercise of any options, warrants or rights at the time outstanding to purchase
shares of Common Stock.
 
     At October 27, 1995, there were 309 shareholders of the Common Stock of
record.
 
PREFERRED STOCK
 
     The Board of Directors has the authority, without further action by the
Company's shareholders, to issue up to 500,000 shares of the Company's Preferred
Stock in one or more series and to fix the voting powers, rights, preferences,
privileges and restrictions thereof.
 
     The existence of authorized but unissued shares of the Preferred Stock and
the issuance of shares of the Preferred Stock could have the effect of delaying,
deferring or preventing a change in control of the Company. The Board of
Directors, without shareholder approval, could issue shares of the Preferred
Stock with voting and conversion rights which could adversely affect the voting
power of the holders of shares of the Common Stock and could adversely affect
the value of the Debentures. In addition, such shares of the Preferred Stock
could have other rights, including economic rights, senior to shares of the
Common Stock, and, as a result, the issuance thereof could have a material
adverse effect on the market value of shares of the Common Stock and
 
                                       33
<PAGE>   39
 
the Debentures. Currently there are no shares of the Preferred Stock
outstanding, and the Company has no present plan to issue any shares of the
Preferred Stock.
 
SHAREHOLDER AGREEMENT
 
     Certain shareholders of the Company, which include Rand W. Mueller, Kenneth
M. Mueller and Larry Vingelman (the "Principal Shareholders"), entered into a
Shareholder Agreement dated May 29, 1987, as amended (the "Shareholder
Agreement"), pursuant to which such shareholders vote their shares as a unit in
accordance with the desires of a plurality of the shares held by the Principal
Shareholders. The Principal Shareholders have voting control of 30.2% of the
outstanding shares of Common Stock (       percent upon conversion of all of the
Debentures offered herein). Any additional Common Stock acquired by the
Principal Shareholders is subject to the voting provisions of the Shareholder
Agreement. The shares held by the Principal Shareholders are subject to certain
rights of first refusal among the Principal Shareholders prior to a third party
sale and certain options to purchase shares upon the death of any Principal
Shareholder. These rights and options may be waived by shareholders holding more
than two-thirds of the shares subject to the Shareholder Agreement. The
Shareholder Agreement terminates on the earlier of May 28, 1997 or a date
selected by shareholders owning greater than two-thirds of the shares subject to
the Shareholder Agreement.
 
PROVISIONS AFFECTING BUSINESS COMBINATIONS
 
     Chapters 7A and 7B of the Michigan Business Corporation Act ("MBCA") may
affect attempts to acquire control of the Company. In general, under Chapter 7A,
"business combinations" (defined to include, among other transactions, certain
mergers, dispositions of assets or shares and recapitalizations) between covered
Michigan business corporations or their subsidiaries and an "interested
shareholder" (defined as the direct or indirect beneficial owner of at least 10%
of the voting power of a covered corporation's outstanding shares) can be
consummated only if approved by at least 90% of the votes of each class of the
corporation's shares entitled to vote and by at least two-thirds of such voting
shares not held by the interested shareholder or such shareholder's affiliates,
unless five years have elapsed after the person involved became an "interested
shareholder" and unless certain price and other conditions are satisfied. The
Board of Directors may exempt "business combinations" with a particular
"interested shareholder" by resolution adopted prior to the time the "interested
shareholder" attained that status.
 
     In general, under Chapter 7B of the MBCA, an entity that acquires "Control
Shares" of the Company may vote the Control Shares on any matter only if a
majority of all shares, and of all non-"Interested Shares," of each class of
shares entitled to vote as a class, approve such voting rights. Interested
Shares are shares owned by officers of the Company, employee-directors of the
Company and the entity making the Control Share Acquisition. Control Shares are
shares that, when added to shares already owned by an entity, would give the
entity voting power in the election of directors over any of three thresholds:
one-fifth, one-third and a majority. The effect of the statute is to condition
the acquisition of voting control of a corporation on the approval of a majority
of the pre-existing disinterested shareholders. The Board of Directors has the
option of choosing to amend the Company's Bylaws before a Control Share
Acquisition occurs to provide that Chapter 7B does not apply to the Company.
 
     The Company currently is subject to Chapters 7A and 7B of the MBCA.
 
TRANSFER AGENT AND REGISTRAR
 
     Boston Financial Data Services is the transfer agent and registrar for
shares of the Common Stock.

<PAGE>   40

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and
Shareholders of Code-Alarm, Inc.
 
     We have audited the accompanying consolidated balance sheets of Code-Alarm,
Inc. and subsidiaries as of December 31, 1994 and 1993, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended December 31, 1994. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Code-Alarm, Inc. and
subsidiaries as of December 31, 1994 and 1993, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1994 in conformity with generally accepted accounting principles.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BUSINESS OPERATIONS
 
     The Company designs, manufactures, imports and markets automobile and home
security systems, keyless entry systems and related products. The Company is
also a contract manufacturer of electronic cable, wire harness and printed
circuit board assemblies.
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries. Significant intercompany accounts and
transactions have been eliminated.
 
CASH AND CASH EQUIVALENTS
 
     The Company considers all highly liquid investments with an initial
maturity of three months or less to be cash equivalents.
 
INVENTORIES
 
     Inventories are stated at the lower of cost or market. The cost of
substantially all inventories is determined on the first-in, first-out ("FIFO")
method.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost. Depreciation is being provided
using the straight-line and accelerated methods over the estimated useful lives
of the related assets. Upon retirement or disposal of property or equipment, the
cost and accumulated depreciation are removed from the accounts, and any gain or
loss is included in income.
 
INTANGIBLE ASSETS
 
     The excess of acquisition cost over net assets acquired is amortized on a
straight-line basis over 40 years. The costs of all other intangible assets,
comprised primarily of covenants-not-to-compete and patents and trademarks, are
amortized on a straight-line basis over their respective estimated useful lives,
generally five years. Accumulated amortization of intangible assets amounted to
approximately $1,100,000, $1,643,000 and $1,499,000 at December 31, 1993 and
1994 and September 30, 1995, respectively.
 
REVENUE RECOGNITION
 
     Revenues are recognized from sales when a product is shipped. The Company
provides an accrual for future product return and warranty costs based upon the
relationship of prior years' sales to costs incurred. Accrued warranty costs
amounted to approximately $400,000, $300,000 and $355,000 at December 31, 1993
and 1994 and September 30, 1995, respectively.
 
RESEARCH AND DEVELOPMENT COSTS
 
     Expenditures for the research and development of new and improved products
are charged to operations as incurred and aggregated approximately $342,000,
$358,000 and $572,000 for the years ended December 31, 1992, 1993 and 1994 and
$429,000 and $454,000 for the nine months ended September 30, 1994 and 1995.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
INCOME TAXES
 
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes." Under SFAS
109, deferred taxes are recorded based upon differences between the financial
statement and tax basis of assets and liabilities.
 
EARNINGS PER COMMON SHARE
 
     Shares issuable under employee stock options were excluded from the
computation of the weighted average number of common shares since they were
either antidilutive or their dilutive effect was not material.
 
FOREIGN CURRENCY TRANSLATION
 
     The functional currency for the majority of the Company's foreign
operations is the French franc. The translation from the franc to U. S. dollars
is performed for balance sheet accounts using current exchange rates in effect
at the balance sheet date and for revenue and expense accounts using a weighted
average exchange rate during the period. The gains or losses, net of applicable
deferred income taxes, resulting from translation are included in shareholders'
equity, gains or losses resulting from foreign currency transactions are
included in the statement of operations.

     In 1994 the Company had a loan agreement with Comerica Bank. The $7,500,000
revolving credit provision of the loan agreement was due June 30, 1997 and was
collateralized by accounts receivable, inventory and property and equipment. At
the Company's option, the interest rate was at Comerica Bank's prime rate or at
fixed interest rates equal to the London Interbank Offered Rate ("LIBOR"). The
Company also agreed to pay a commitment fee equal to three-eighths of one
percent per annum on the difference between $6,000,000 and the outstanding
balance.
 
     This loan agreement was subject to covenants for maintenance of certain
debt and cash flow ratios and minimum levels of current assets and tangible net
worth. At December 31, 1994, the Company was not in compliance with certain
covenants; however, Comerica Bank, at the Company's request, waived the covenant
violations.
 
     Term loans were payable in equal quarterly installments of $209,000 through
1999. At the Company's option, the interest rate was at the Comerica Bank's
prime rate (8.5% at December 31, 1994) or at fixed interest rates ranging from
one to one and three-quarter percent above LIBOR on a designated portion of the
outstanding loan.
 
     In May 1995 the above described loan agreement was replaced with a new
credit arrangement with NBD Bank. The new credit arrangement provides for a
$13.75 million revolving credit facility for working capital requirements, $1.3
million secured non-amortizing notes and $2.2 million unsecured in 4 year term
notes. The revolving credit facility expires in May 1997 and bears interest at
NBD Bank's prime rate (8.75% at October 31, 1995) or at the Company's option at
the London InterBank Offered Rate (LIBOR) plus 2.5% for maturities ranging from
one to six months (8.332% and 8.375%, respectively, at October 31, 1995). At
September 30, 1995 a standby letter of credit in the amount of $5.9 million has
been issued under the revolving credit facility in conjunction with the appeal
of the patent infringement settlement as discussed in Note 9.
 
     The credit facility is subject to covenants which require certain debt and
cash flow ratios, minimum levels of current assets and tangible net worth,
restrict the payment of dividends and is collateralized by substantially all the
assets of the Company and its domestic subsidiaries. Total credit available
under the arrangement is subject to a formula of accounts receivable,
inventories and appraised value of property and equipment assets. As of
September 30, 1995, the Company was in default with certain of the covenants.
NBD Bank has agreed to amend the credit agreement as of September 30, 1995. Such
amendment, when effective, will place the Company in compliance.

     A foreign subsidiary of the Company has a credit arrangement with its
commercial bank which includes term loans totaling approximately $2.1 million,
with interest rates ranging from 8% to 11%. Payments are due monthly, with final
payments due in 1996.
 
     The Company has working capital facilities with three French lenders. These
loans bear interest at rates of 8.8 percent to 11.5 percent and require
quarterly principal payments of approximately $125,000 through 1997.
 
     The mortgage note is payable to the City of Georgetown, Texas, in monthly
installments of $4,401, including interest at seven percent per annum, through
January of 2005, and is collateralized by the leasehold improvements.

6. CAPITAL STOCK
 
STOCK OPTION PLAN
 
     The Company has adopted a Stock Option Plan ("Plan") for its key employees
and reserved 280,000 shares of common stock for issuance under the Plan. The
Plan authorizes the Company to issue Incentive Stock Options and Non-Qualified
Stock Options. The Company may grant such options concurrently with Stock
Appreciation Rights, which entitle the Company to accept surrender of an option
by paying the employee an amount equal to the increase in the price of the
Company's common stock from the option date.
 
     Incentive Stock Options may be issued at a price not less than fair market
value as of the grant date. For any employee holding more than 10 percent of the
voting stock of the Company, the option price is 110 percent of fair market
value at the grant date.
 
     Non-Qualified Stock Options may be issued at a price not less than 85
percent of fair market value at the grant date. Options are generally
exercisable for a ten-year period; however, options granted to any employee
holding more than 10 percent of the voting stock of the Company are exercisable
over five years. No Non-Qualified Stock Options have been granted.
 
     The following is a summary of Incentive Stock Options, with Stock
Appreciation Rights, granted under the Plan:

     These options and rights were issued at various prices ranging from $4.25
per share to $22.28 per share. At December 31, 1994, 61,175 options were
exercisable at prices ranging from $4.25 to $20.25 per share. In 1994, 1,200
Stock Options and Stock Appreciation Rights were exercised at $4.25 to $5.00 per
share.
 
7. ACQUISITIONS
 
     Effective January 1, 1994, the Company purchased Europe Auto Equipement
Company ("EAE"), a French based distributor of vehicle security products.
Consideration included $1.6 million and 50,000 shares of the Company's common
stock. Also, effective January 1, 1994, the Company purchased Code-Europe, Ltd.,
a distributor of vehicle security products in the United Kingdom, for 40,000
shares of the Company's common stock.
 
     These acquisitions were accounted for as purchases, with the results of
their operations included from January 1, 1994. The fair value of assets
acquired, including goodwill, was $8,766,000, and liabilities assumed totaled
$6,389,000. Goodwill of $1,230,000 is being amortized over 40 years on a
straight-line basis.
 
     As part of the consideration given in the acquisition of EAE, the Company
may pay the sellers up to 2,000,000 French francs ($1 U. S. equals 5.355 French
franc at December 31, 1994) based upon EAE's 1994 sales and satisfaction of
certain other conditions. Any additional payments will be treated as additional
purchase considerations in 1995, increasing intangible assets.

income taxes of approximately $41,000 at December 31, 1994.

9. LITIGATION
 
     The Company is involved in a patent infringement suit involving a shock
sensing device. During 1993, an appeals court found the Company to be in
violation of the patent. The damage portion of the trial was completed in
January 1995 and at December 31, 1994, the Company recorded an accrual for
damages, including interest and costs, of approximately $4.2 million. In June
1995 the Company received from the United States District Court information that
the damages would total $6.0 million. Accordingly the Company has recorded an
additional accrual for damages of $1.8 million in 1995. The Company believes
that any amount paid will be paid after 1995, or it will be financed with
long-term debt. The Company's reserve for litigation and litigation expense
include this estimate of damages and incidental professional fees and costs.
 
     During 1993, the Company became involved in several legal proceedings
following the Company's decision to aggressively defend its patent rights. The
Company is asserting its patent rights against the defendants in these cases,
and such defendants have made claims against the Company. The outcome of these
cases cannot be reasonably estimated.
 
     Various legal actions and other claims are pending or could be asserted
against the Company. Litigation is subjected to many uncertainties; the outcome
of individual litigated matters is not predictable with assurance, and it is
reasonably possible that some of these matters may be decided unfavorably to the
Company. It is the opinion of management that the ultimate liability, if any,
with respect to these matters will not materially affect the financial position
of the Company.
 
10. SIGNIFICANT CUSTOMERS
 
     The Company operates primarily in one business segment -- vehicle security
systems. This segment represents more than 90 percent of consolidated revenue,
operating profit and identifiable assets. With the exception of sales to dealers
of General Motors Corporation ("GM") and Ford Motor Company ("Ford"), no single
customer accounted for more than 10 percent of revenue.

     Each amount set forth above, except for the SEC registration fee and the
NASD filing fee, is estimated.
 
ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Michigan Business Corporation Act.  The Registrant is organized under the
MBCA which, in general, empowers Michigan corporations to indemnify a person who
was or is a party or threatened to be made a party to any threatened, pending or
completed action, suit, or proceeding, whether civil, criminal, administrative
or investigative and whether formal or informal other than actions by or in the
right of the corporation, by reason of the fact that he or she is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, partner, trustee,
employee or agent of another foreign or domestic corporation, partnership, joint
venture, trust or other enterprise, whether for profit or not, against expenses,
judgments, penalties, fines and amounts paid in settlement actually and
reasonably incurred by him or her in connection with such action, suit or
proceeding if the person acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
corporation or its shareholder, and with respect to any criminal action or
proceeding, if the person had no reasonable cause to believe his or her conduct
was unlawful.
 
     The MBCA also empowers Michigan corporations to provide similar indemnity
to such a person for expenses and amounts paid in settlement, actually and
reasonably incurred, in actions or suits by or in the right of the corporation
except in respect of any claim, issue or matter as to which such person has been
found liable to the corporation, unless and only to the extent that a court
determines that, despite the adjudication of the liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity.
 
     The MBCA also empowers Michigan corporations to pay or reimburse the
reasonable expenses incurred by such persons in advance of a final disposition
of the proceeding; provided, among other things, that the person undertake to
repay the amount advanced if it is ultimately determined that he or she did not
meet the necessary standard of conduct.
 
     Articles of Incorporation and Bylaws.  The Registrant's Restated Articles
of Incorporation and Restated Bylaws generally provide that directors and
officers will be indemnified to the fullest extent permissible under Michigan
law against all expenses (including amounts paid in settlement) incurred in any
proceeding (whether or not such proceeding was by or in the right of the
Registrant) in which they were a party because of their position as a director
or officer of the Registrant or because they served at the request of the
Registrant as a director, officer, employee or agent of another corporation or
entity. The provisions also provide for the advancement of litigation expenses.
The Registrant has the burden of proof to show such indemnification to be
improper.
 
                                      II-1
<PAGE>   59
 
     Indemnification Agreements.  The Registrant has entered into
indemnification agreements in the form incorporated by reference as Exhibit 10.4
to this Registration Statement, with each of its officers and members of its
Board of Directors. The indemnification agreements contain the same general
provisions as the indemnification provision in the Restated Articles of
Incorporation and Bylaws but establishes a separate contractual basis for such
indemnification and contains an undertaking to repay by the indemnitee any
amounts advanced if it is determined that such advance was improper.
 
     Reference is also made to the Undertaking contained in Item 17 of this
Registration Statement.

ITEM 17.  UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

THE OHIO COMPANY
c/o Roney & Co.

Ladies and Gentlemen:

  Code-Alarm, Inc., a Michigan corporation (the "Company"), hereby confirms its
agreement with Roney & Co. and The Ohio Company (the "Underwriters") as set
forth below.

  1. Securities.  Subject to the terms and conditions herein contained, the
Company proposes to issue and sell to the Underwriters an aggregate of
$10,000,000 principal amount of ____% Convertible Subordinated Debentures due
December 1, 2002.  Such $10,000,000 principal amount of Debentures are
referred to in this Agreement as the "Firm Debentures".  The Company also
proposes to issue and sell to the Underwriters not more than an aggregate of
$1,500,000 principal amount of additional Debentures if requested by the
Underwriters as provided in Section 3 of this Agreement.  Any and all
Debentures to be purchased by the Underwriters pursuant to such options are
referred to in this Agreement as the "Option Debentures," and the Firm
Debentures and any Option Debentures are collectively referred to in this
Agreement as the "Debentures."  The Debentures are to be issued pursuant to an
indenture to be dated as of ___________, 1995 (the "Indenture") between the
Company and State Street Bank and Trust Company (the "Trustee").

  2. Representations and Warranties of the Company.  The Company represents and
warrants to, and agrees with, each of the Underwriters that:

   (a)   The Company meets the requirements for use of Form S-2 under the
Securities Act of 1933, as amended, and the rules and regulations of the
Securities and Exchange Commission (the "Commission") thereunder (collectively,
the "Act").  A registration statement on such Form (File No. 33-________) with
respect to the Debentures, which may be converted into Common Shares, without
par value, of the Company (the "Common Shares") as provided in the Indenture
(the "Underlying Common Shares") (together, the "Securities"), including a
prospectus subject to completion, has been prepared and filed by the Company
with the
<PAGE>   2

Commission in accordance with the provisions of the Act, and one or more
amendments to such registration statement may have been so filed.  As soon as
practicable after the execution of this Agreement, the Company will file with
the Commission either (1) if such registration statement, as it may have been
amended, has been declared by the Commission to be effective under the Act, a
prospectus in the form most recently included in an amendment to such
registration statement (or, if no such amendment shall have been filed, in such
registration statement), with such changes or insertions as are required by
Rule 430A under the Act or permitted by Rule 424(b) under the Act and as have
been provided to and approved by the Underwriters prior to the execution of
this Agreement, or (2) if such registration statement, as it may have been
amended, has not been declared by the Commission to be effective under the Act,
an amendment to such registration statement, including a form of prospectus, a
copy of which amendment has been furnished to and approved by the Underwriters
prior to the execution of this Agreement.  As used in this Agreement, the term
"Registration Statement" means such registration statement, as amended at the
time when it was or is declared effective, and, in the event of any amendment
to such registration statement after the effective date and before the Firm
Closing Date and any Option Closing Date (as defined in Sections 3(a) and 3(b),
respectively), such registration statement as so amended, but only from and
after the effectiveness of such amendment, including (1) all financial
statements, schedules and exhibits thereto, (2) all documents (or portions
thereof) incorporated by reference therein filed under the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), and (3) any information omitted
therefrom pursuant to Rule 430A under the Act and included in the Prospectus
(as hereinafter defined).  As used in this Agreement, the term "Preliminary
Prospectus" means each prospectus subject to completion filed with such
registration statement or any amendment thereto (including the prospectus
subject to completion, if any, included in the Registration Statement or any
amendment thereto at the time it was or is declared effective), including all
documents (or portions thereof) incorporated by reference therein filed under
the Exchange Act.  As used in this Agreement, the term "Prospectus" means the
prospectus first filed with the Commission pursuant to Rule 424(b) under the
Act or, if no prospectus is required to be filed pursuant to said Rule 424(b),
such term means the prospectus included in the Registration Statement, at the
time the Registration Statement or any amendment thereto became effective, and,
in the event of any supplement or amendment to such prospectus before the Firm
Closing Date and any Option Closing Date, such prospectus as so supplemented or
amended but only from and after the filing with the Commission of such
supplement or  the effectiveness of such amendment, in any case including all
documents (or portions thereof) incorporated by reference therein filed under
the Exchange Act.

   (b)   The Commission has not issued any order preventing or suspending the
use of any Preliminary Prospectus.  When any Preliminary Prospectus was filed
with the Commission, it (1) contained all statements required to be stated
therein in accordance with, and complied in all material respects with the
requirements of, the Act, the Exchange Act, the Trust Indenture Act of 1939 as
amended, if required (the "Trust Indenture Act"), and the respective rules and
regulations of the Commission thereunder and (2) did not include any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading.  When the Registration Statement or any
amendment thereto was or is declared effective and at all times

                                      2
<PAGE>   3

subsequent thereto up to and including the Firm Closing Date and any Option
Closing Date, it (1) contained or will contain all statements required to be
stated therein in accordance with, and complied or will comply in all material
respects with the requirements of, the Act, the Trust Indenture Act, if
required, the Exchange Act and the respective rules and regulations of the
Commission thereunder and (2) did not or will not include any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.  When the Prospectus
or any amendment or supplement thereto is filed with the Commission pursuant to
Rule 424(b) (or, if the Prospectus or such amendment or supplement is not
required to be so filed, when the Registration Statement or the amendment
thereto containing such amendment or supplement to the Prospectus was or is
declared effective), on the date when the Prospectus is otherwise amended or
supplemented and at all times subsequent thereto up to and including the Firm
Closing Date and any Option Closing Date (as defined in Sections 3(a) and 3(b),
respectively), the Prospectus, as amended or supplemented at any such time, (1)
contained or will contain all statements required to be stated therein in
accordance with, and complied or will comply in all material respects with the
requirements of, the Act, the Trust Indenture Act, if required, the Exchange
Act and the respective rules and regulations of the Commission thereunder and
(2) did not or will not include any untrue statement of a material fact or omit
to state any material fact necessary in order to make the statements therein,
in light of the circumstances under which they were made, not misleading.  The
foregoing provisions of this paragraph (b) do not apply to statements or
omissions made in any Preliminary Prospectus, the Registration Statement or any
amendment thereto or the Prospectus or any amendment or supplement thereto in
reliance upon, and in conformity with, written information furnished to the
Company by you specifically for use therein.

   (c)   The Company's only subsidiaries are listed on Schedule 1 to this
Agreement.  The Company and each of its subsidiaries have been duly organized
and are validly existing as corporations in good standing under the laws of
their respective jurisdictions of incorporation and are duly qualified to
transact business as foreign corporations and are in good standing under the
laws of all other jurisdictions where the ownership or leasing of their
respective properties or the nature or conduct of their respective businesses
requires such qualification, except where the failure to be so qualified would
not have a material adverse effect on the Company and its subsidiaries, taken
as a whole.

   (d)   The Company and each of its subsidiaries have full power (corporate
and other) to own or lease their respective properties and conduct their
respective businesses as described in the Registration Statement and the
Prospectus or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus; and the Company has full power (corporate and other) to
enter into this Agreement and to carry out all the terms and provisions of this
Agreement to be carried out by it.

   (e)   The authorized, issued and outstanding shares of capital stock of each
of the Company's subsidiaries are set forth on Schedule 2 to this Agreement.
Such issued and outstanding shares have been duly authorized and validly
issued, are fully paid and nonassessable





                                       3
<PAGE>   4

and are all owned beneficially by the Company free and clear of all
restrictions on transfer (other than those imposed by the Act and the
securities or Blue Sky laws of various jurisdictions) and any security
interests, liens, encumbrances, equities and claims.

   (f)   The Company has an authorized, issued and outstanding capitalization
as set forth in the Prospectus or, if the Prospectus is not in existence, the
most recent Preliminary Prospectus, under the caption "Capitalization."  All of
the issued and outstanding shares of capital stock of the Company have been
duly authorized and validly issued and are fully paid and nonassessable and
free of preemptive rights and contractual rights to purchase other than the
Company's stock option plan and except as described in or contemplated by the
Prospectus (or, if the Prospectus is not in existence, the most recent

contingent, nor entered into any material transaction not in the ordinary
course of business; (2) the Company has not purchased any of its outstanding

distribution of any kind on its capital stock; and (3) there has not been any
change in the capital stock, short-term debt or long-term debt of the Company
and its consolidated subsidiaries or any material loss or damage to the
property of the Company or any of its subsidiaries, any material adverse change
in the condition (financial or otherwise), business, results of operations,
cash flows or prospects of the Company and its subsidiaries, taken as a whole,
except in each case as described in or contemplated by the Prospectus (or, if
the Prospectus is not in existence, the most recent Preliminary Prospectus).

   (q)   The Company and each of its subsidiaries have good and marketable
title in fee simple to all items of real property and good and marketable title
to all personal property owned by each of them or described in the Prospectus

encumbrances, equities, claims, charges, restrictions and other defects, except
the pledge of the capital stock of the Company's subsidiaries to NBD Bank to
secure the Company's current senior indebtedness and except such as do not
materially and adversely affect the value of such property and do not interfere
with the use made or proposed to be made of such property by the Company or
such subsidiary, and any real and personal property and buildings held under
lease by the Company or any such subsidiary are held under valid, subsisting
and enforceable leases, with such exceptions as are not material and do not
interfere with the use made or proposed to be made of such property and
buildings by the Company or such subsidiary, in each case mentioned in this
paragraph except as described in or contemplated by the Prospectus (or, if the
Prospectus is not in existence, the most recent Preliminary Prospectus).  The
Company and its subsidiaries own or lease all properties as are necessary to
its operations as now conducted and, except as otherwise stated in the
Prospectus (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus), as proposed to be conducted as set forth in the
Prospectus.

   (r)   No labor dispute with the employees of the Company or any of its
subsidiaries exists or is threatened or imminent that could result in a
material adverse change in the condition (financial or otherwise), business

flows of the Company and its subsidiaries, except as described in or

reasonable terms, all material patents, patent applications, trademarks,
service marks, trade names, licenses, copyrights and proprietary or other
confidential information currently employed by them in connection with their
respective businesses, and neither the Company nor any such subsidiary has
received any notice of infringement of or conflict with asserted rights of any
third party with respect to any of the foregoing which, singly or in the

result in a material adverse change in the condition (financial or otherwise),
business prospects, net worth, results of operations or cash flows of the
Company and its subsidiaries, except as described in or contemplated by the
Prospectus (or, if the Prospectus is not in existence, the most recent

if the Prospectus is not in existence, the most recent Preliminary Prospectus).

   (t)   The Company and each of its subsidiaries are insured by insurers of
recognized financial responsibility against such losses and risks and in such
amounts as are prudent and customary in the businesses in which they are
engaged.  Neither the Company nor any such subsidiary has been refused any
insurance coverage sought or applied for, and neither the Company nor any such
subsidiary has any reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not materially and adversely affect the condition
(financial or otherwise), business prospects, net worth, results of operations
or cash flows of the Company and its subsidiaries, except as described in or
contemplated by the Prospectus (or, if the Prospectus is not in existence, the
most recent Preliminary Prospectus).

any loans or advances to such subsidiary from the Company or from transferring
any of such subsidiary's property or assets to the Company or any other
subsidiary of the Company, except as described in or contemplated by the
Prospectus (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus) and except to the extent that the Company has pledged
the capital stock of the Company's subsidiaries to NBD Bank to secure the
Company's current senior indebtedness.

   (v)   The Company and its subsidiaries possess all certificates,
authorizations and permits issued by the appropriate federal, state or foreign
regulatory authorities necessary to conduct their respective businesses, and

                                       7

<PAGE>   8

certificate, authorization or permit which, singly or in the aggregate, if the
subject of an unfavorable decision, ruling or finding, would result in a
material adverse change in the condition (financial or otherwise), business
prospects, net worth, results of operations or cash flows of the Company and
its subsidiaries, except as described in or contemplated by the Prospectus (or,
if the Prospectus is not in existence, the most recent Preliminary Prospectus).

   (w)   The Company will conduct its operations in a manner that will not
subject it to registration as an investment company under the Investment
Company Act of 1940, as amended, and this transaction will not cause the
Company to become an investment company subject to registration under such Act.

   (x)   The Company has filed all foreign, federal, state and local tax
returns that are required to be filed or has requested extensions thereof
(except in any case in which the failure so to file would not have a material
adverse effect on the Company and its subsidiaries) and has paid all taxes
required to be paid by it and any other assessment, fine or penalty levied
against it, to the extent that any of the foregoing is due and payable, except
for any such assessment, fine or penalty that is currently being contested in
good faith or as described in or contemplated by the Prospectus (or, if the
Prospectus is not in existence, the most recent Preliminary Prospectus).

   (y)   Neither the Company nor any of its subsidiaries is in violation of any
federal, state or foreign law or regulation relating to occupational safety and
health or to the storage, handling or transportation of hazardous or toxic
materials, and the Company and its subsidiaries have received all permits,
licenses or other approvals required of them under applicable federal, state
and foreign occupational safety and health and environmental laws and
regulations to conduct their respective businesses, and the Company and each
such subsidiary is in compliance with all terms and conditions of any such
permit, license or approval, except any such violation of law or regulation,
failure to receive required permits, licenses or other approvals or failure to
comply with the terms and conditions of such permits, licenses or approvals
which would not, singly or in the aggregate, result in a material adverse
change in the condition (financial or otherwise), business prospects, net
worth, results of operations or cash flows of the Company and its subsidiaries,
except as described in or contemplated by the Prospectus (or, if the Prospectus
is not in existence, the most recent Preliminary Prospectus).

   (z)   Each certificate signed by any officer of the Company and delivered to
the Underwriters or counsel for the Underwriters shall be deemed to be a
representation and warranty by the Company to each Underwriter as to the
matters covered thereby.

   (aa)  Except for the shares of capital stock of each of the subsidiaries
owned by the Company and such subsidiaries, neither the Company nor any such
subsidiary owns any shares of stock or any other equity securities of any
corporation or has any equity interest in any firm, partnership, association or
other entity, except as described in or contemplated by the Prospectus (or, if
the Prospectus is not in existence, the most recent Preliminary Prospectus).

   (bb)  There is no holder of securities of the Company, who, by reason of the
filing of the Registration Statement, has the right to request the Company to
register under the Act, or to include in the Registration Statement, securities
held by such holder, except to the extent such holder has waived such rights in
writing or except as described in or contemplated by the Prospectus (or, if the
Prospectus is not in existence, the most recent Preliminary Prospectus).

   (cc)  The Company and each of its subsidiaries maintain a system of internal
accounting controls sufficient to provide reasonable assurance that (1)
transactions are executed in accordance with management's general or specific
authorizations; (2) transactions are recorded as necessary to permit
preparation of financial statements in conformity with generally accepted
accounting principles and to maintain asset accountability; (3) access to
assets is permitted only in accordance with management's general or specific
authorization; and (4) the recorded accountability for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken
with respect to any differences.

   (dd)  No default exists, and no event has occurred which, with notice or
lapse of time or both, would constitute a default, in the due performance and
observance of any term, covenant or condition of any bond, debenture,
indenture, note, evidence of indebtedness, mortgage, deed of trust, lease or
other agreement or instrument to which the Company or any of its subsidiaries
is a party or by which the Company or any of its subsidiaries or any of their
respective properties is bound or may be affected in any material adverse
respect with regard to property, business or operations of the Company and its

  3. Purchase, Sale and Delivery of the Debentures.

   (a)   On the basis of the representations, warranties, agreements and
covenants contained in this Agreement and subject to the terms and conditions
set forth in this Agreement, the Company agrees to sell to each of the
Underwriters, and each of the Underwriters, individually and not jointly,
agrees to purchase from the Company, at a purchase price equal to ____% of the
principal amount, the respective principal amount of Firm Debentures set forth
opposite the name of such Underwriter in Schedule 3 to this Agreement.  One or
more certificates in definitive form for the Firm Debentures that the several
Underwriters have agreed to purchase under this Agreement, and in such
denomination or denominations and registered in such name or names as you
request upon notice to the Company at least 48 hours prior to the Firm Closing
Date, shall be delivered by or on behalf of the Company to you on the Closing
Date for the





                                       9

<PAGE>   10

respective accounts of the several Underwriters, against payment by or on
behalf of the Underwriters of the purchase price therefor by certified or
official bank checks drawn upon or by a New York Clearing House bank and
payable in next-day funds to the order of the Company or at the option of the
Underwriters, by wire transfer to the account of the Company in same-day funds.
Such delivery of, and payment for, the Firm Debentures shall be made at the
offices of Clark, Klein & Beaumont P.L.C., 1600 First Federal Building,
Detroit, Michigan 48226, at 9:30 A.M., Detroit time, on ______________, 1995,
or at such other place, time or date as you and the Company may agree upon or
as you may determine pursuant to Section 9 of this Agreement, such time and
date of delivery against payment being referred to in this Agreement as the
"Firm Closing Date".  The Company will make such certificate or certificates
for the Firm Debentures available to you for inspection at the offices in
Madison Heights, Michigan of the Company's transfer agent or registrar or of
Roney & Co. at least 24 hours prior to the Firm Closing Date.

   (b)   For the purpose of covering any over-allotments in connection with the
distribution and sale of the Firm Debentures as contemplated by the Prospectus,
the Company hereby grants to the Underwriters options to purchase, individually
and not jointly, the Option Debentures.  The purchase price to be paid for any
Option Debentures shall be the same as the price for the Firm Debentures set
forth above in paragraph (a) of this Section 3, plus accrued interest from
______________, 1995 to the Option Closing Date.  The options granted hereby
may be exercised as to all or any part of the Option Debentures from time to
time within 30 days after the date of the Prospectus (or, if such 30th day
shall be a Saturday or a Sunday or a holiday, on the next business day
thereafter when the New York Stock Exchange is open for trading).  The
Underwriters shall not be under any obligation to purchase any of the Option
Debentures prior to the exercise of such options.  The Underwriters may from
time to time exercise the options granted hereby by giving notice in writing or
by telephone (confirmed in writing) to the Company setting forth the aggregate
principal amount of Option Debentures as to which the Underwriters are then
exercising the options and the date and time for delivery of and payment for
such Option Debentures.  Any such date of delivery shall be determined by the
Underwriters but shall not be earlier than two business days or later than
seven business days after such exercise of the options and, in any event, shall
not be earlier than the Firm Closing Date.  The time and date set forth in such
notice, or such other time, date or both as the Underwriters and the Company
may agree upon or as the Underwriters may determine pursuant to Section 9 of
this Agreement, are called the "Option Closing Date" in this Agreement with
respect to such Option Debentures.  Upon exercise of the options as provided in
this Agreement, the Company shall become obligated to sell to each of the
Underwriters, and, on the basis of the representations and warranties contained
in this Agreement and subject to the terms and conditions set forth in this
Agreement, each of the Underwriters, individually and not jointly, shall become
obligated to purchase from the Company, the same percentage of the total
principal amount of the Option Debentures as to which the Underwriters are then
exercising the options as such Underwriter is obligated to purchase of the
aggregate number of Firm Debentures (subject to such adjustments to provide for
purchases of Debentures in principal amounts that are even multiples of $1,000
as you may determine).  If the options are exercised as to all or any portion
of the Option Debentures, one or more certificates in definitive form for such
Option Debentures,





                                       10

<PAGE>   11

and payment therefor, shall be delivered on the related Option Closing Date in
the manner, and upon the terms and conditions, set forth in paragraph (a) of
this Section 3, except that reference therein to the Firm Debentures and the
Firm Closing Date shall be deemed, for purposes of this paragraph (b), to refer
to such Option Debentures and Option Closing Date, respectively.

  4. Offering by the Underwriters.  Upon our authorization of the release of
the Firm Debentures, the Underwriters propose to offer their respective
portions of the Firm Debentures for sale to the public upon the terms set forth
in the Prospectus.

  5. Covenants.  Covenants of the Company.  The Company covenants and agrees
     with each of the Underwriters that:

   (a)   The Company will use its best efforts to cause the Registration
Statement, if not effective at the time of execution of this Agreement, and any
amendments thereto, to become effective as promptly as possible.  If required,
the Company will file the Prospectus and any amendment or supplement thereto
with the Commission in the manner and within the time period required by Rule
424(b) under the Act.  During any time when a prospectus relating to the
Securities is required to be delivered under the Act (or until the Firm Closing
Date and any Option Closing Date, if later), the Company (1) will comply with
all requirements imposed upon it by the Act, the Trust Indenture Act, the
Exchange Act and the respective rules and regulations of the Commission
thereunder to the extent necessary to permit the continuance of sales of or
dealings in the Securities in accordance with the provisions of this Agreement
and of the Prospectus, as then amended or supplemented, and (2) will not file
with the Commission the Prospectus or the amendment referred to in the third
sentence of Section 2(a) of this Agreement, any amendment or supplement to such
Prospectus or any amendment to the Registration Statement of which the
Underwriters shall not previously have been advised and furnished with a copy a
reasonable period of time prior to the proposed filing or as to which filing
you shall not have given your consent.  The Company will prepare and file with
the Commission, in accordance with the Act and the rules and regulations on the
Commission, promptly upon request by the Underwriters or counsel for the
Underwriters, any amendments to the Registration Statement or amendments or
supplements to the Prospectus that may be necessary or advisable in connection
with the distribution of the Securities by the Underwriters, and will use its
best efforts to cause any such amendment to the Registration Statement to be
declared effective by the Commission as promptly as possible.  The Company will
advise you, promptly after receiving notice thereof, of the time when the
Registration Statement or any amendment thereto has been filed or declared
effective or the Prospectus or any amendment or supplement thereto has been
filed and will provide evidence satisfactory to you of each such filing or
effectiveness.

   (b)   The Company will advise the Underwriters, promptly after receiving
notice or obtaining knowledge thereof, of (1) the issuance by the Commission of
any stop order suspending the effectiveness of the Registration Statement or
any post-effective amendment thereto or any order directed at any document
incorporated by reference in the Registration Statement or the Prospectus or
any amendment or supplement thereto or any order preventing or suspending the
use of any Preliminary Prospectus or the Prospectus or any amendment or





                                       11

<PAGE>   12

supplement thereto, (2) the suspension of the qualification of the Securities
for offering or sale in any jurisdiction, (3) the institution, threatening or
contemplation of any proceeding for any such purpose or (4) any request made by
the Commission for amending the Registration Statement, for amending or
supplementing any Preliminary Prospectus or the Prospectus or for additional
information.  The Company will use its best efforts to prevent the issuance of
any such stop order and, if any such stop order is used, to obtain the
withdrawal thereof as promptly as possible.

   (c)   The Company will arrange for the registration or qualification of the
Securities for offering and sale under the securities or blue sky laws of such
jurisdictions as you may designate and will continue such qualifications in
effect for as long as may be necessary to complete the distribution of the
Securities, provided, however, that in connection with such qualification the
Company shall not be required to qualify as a foreign corporation or to execute
a general consent to service of process in any jurisdiction.

   (d)   If, at any time prior to the later of (1) the final date when a
prospectus relating to the Securities is required to be delivered under the Act
or (2) the Firm Closing Date and any Option Closing Date, any event occurs as a
result of which the Prospectus, as then amended or supplemented, would include
any untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, or if for any other
reason it is necessary at any time to amend or supplement the Prospectus to
comply with the Act, the Exchange Act, the Trust Indenture Act, the respective
rules or regulations of the Commission thereunder or any other law, the Company
will promptly notify the Underwriters thereof and, subject to Section 5(a) of
this Agreement, will prepare and file with the Commission, at the Company's
expense, an amendment to the Registration Statement or an amendment or
supplement to the Prospectus that corrects such statement or omission or
effects such compliance.

   (e)   The Company will, without charge, provide (1) to each of the
Underwriters and to counsel for the Underwriters a signed copy of the
registration statement originally filed with respect to the Securities and each
amendment thereto (in each case including exhibits thereto), and a conformed
copy of such registration statement and each amendment thereto (in each case
without exhibits thereto) and (2) so long as a prospectus relating to the
Securities is required to be delivered under the Act, as many copies of each
Preliminary Prospectus or the Prospectus or any amendment or supplement thereto
as the Underwriters, counsel for the Underwriters or any dealer may reasonably
request.

   (f)   The Company, as soon as practicable, will make generally available to
its security holders and to the Underwriters a consolidated earnings statement
of the Company and its subsidiaries that satisfies the provisions of Section
11(a) of the Act and Rule 158 thereunder.

   (g)   The Company will apply the net proceeds from the sale of the
Securities sold by the Company as set forth under "Use of Proceeds" in the
Prospectus.

   (h)   The Company will not, directly or indirectly, without your prior
written consent, offer, sell, offer to sell, contract to sell, grant any option
to purchase or otherwise sell or dispose of (or announce any offer, sale, offer
of sale, contract of sale, grant of any option to purchase or other sale or
other disposition of) any Common Shares or any securities convertible into, or
exchangeable or exercisable for, Common Shares for a period of 120 days after
the date of this Agreement except for (1) issuances pursuant to the exercise of
warrants outstanding on the date of this Agreement or pursuant to the exercise
of employee stock options outstanding on the date of this Agreement, or (2) the
grant of employee stock options pursuant to the Company's stock option plans in
effect on the date of this Agreement, provided that any employee stock options
so granted after the date of this Agreement are not exercisable prior to 120
days after the date of this Agreement, or (3) issuances of Common Shares
pursuant to the Company's Employee Stock Purchase Plan, as such plan exists on
the date of this Agreement, or (4) issuances and sales of the Debentures to the
Underwriters pursuant to this Agreement, or (5) issuances of Common Shares upon
conversion of the Debentures.

   (i)   The Company will not, directly or indirectly, (1) take any action
designed to cause or to result in, or that has constituted or which might
reasonably be expected to constitute, the stabilization or manipulation of the
price of any security of the Company to facilitate the sale or resale of the
Securities or (2) (A) sell, bid for, purchase, attempt to induce any person to
purchase, or pay anyone any compensation for soliciting purchases of, the
Securities or (B) pay or agree to pay to any person any compensation for
soliciting another to purchase any other securities of the Company.

   (j)   If at any time during the 25-day period after the Registration
Statement becomes effective or the period prior to the Option Closing Date, any
rumor, publication or event relating to or affecting the Company shall occur as
a result of which in your opinion the market price of the Common Shares has
been or is likely to be materially affected (regardless of whether such rumor,
publication or event necessitates a supplement to or amendment of the
Prospectus), the Company will, after written notice from you advising the
Company to the effect set forth above, forthwith prepare, consult with you
concerning the substance of, and disseminate a press release or other public
statement, reasonably satisfactory to you, responding to or commenting on such
rumor, publication or event.

   (k)   At all times prior to the conversion of the Debentures, the Underlying
Common Shares shall remain duly authorized and duly reserved for issuance.

   (l)   For a period of three years from the effective date of the
Registration Statement, the Company shall furnish to you copies of all public
reports filed by the Company and all reports and financial statements furnished
by the Company to its shareholders, The Nasdaq Stock Market, any stock exchange
upon which the Company's securities are traded, or to the Commission pursuant
to the Exchange Act or any rule or regulation of the Commission under the

  6. Expenses.

   (a)   The Company will pay all costs, expenses, fees and taxes incident to
the performance of its obligations under this Agreement, whether or not the
transactions contemplated by this Agreement are consummated or this Agreement
is terminated pursuant to Section 11 of this Agreement, including all costs,
expenses fees and taxes incident to (1) the preparing, printing or other
production and filing of documents with respect to the transactions, including
any costs of printing the registration statement originally filed with respect
to the Securities and any amendment thereto (including, without limitation, the
Registration Statement), any Preliminary Prospectus and the Prospectus and any
amendment or supplement thereto, this Agreement, the Agreement Among
Underwriters, the Selected Dealer Agreement, the Underwriters' Questionnaire
and Power of Attorney, any blue sky memoranda and all other agreements,
memoranda, correspondence and other documents printed and delivered in
connection with the offering of the Securities, (2) all arrangements relating
to the delivery to the Underwriters of copies of the foregoing documents, (3)

offering of the Securities (other than as shall have been specifically approved
by the Underwriters to be paid for by the Underwriters).  If the sale of the
Securities provided for in this Agreement is not consummated because any
condition to the obligations of the Underwriters set forth in Section 7 of this
Agreement is not satisfied, because this Agreement is terminated pursuant to
Section 11 of this Agreement, because of any failure, refusal or inability on
the part of the Company to perform all obligations and satisfy all conditions
on its or their part to be performed or satisfied under this Agreement (other
than by reason of a default by any of the Underwriters) or for any other reason
(other than because of the Underwriters' refusal (except for bona fide reasons
related to the Company, its officers, directors, employees or agents or market
conditions) or inability to perform), the Company will reimburse the
Underwriters individually upon demand for all out-of- pocket expenses
(including reasonable fees and disbursements of counsel) that shall have been
incurred by them in connection with the proposed purchase and sale of the
Securities.  The Company shall not in any event be liable to any of the
Underwriters for the loss of anticipated profits from the transactions covered
by this Agreement.

   (b)   The provisions of paragraph 10 of the letter of intent dated August
16, 1995 among the Company and the Underwriters, a copy of which is attached as
Exhibit 6(b) to this Agreement (the "Letter of Intent"), which provisions
provide for payments of fees and reimbursement of expenses incurred in
connection with the Underwriters' engagement by the Company, are incorporated
into, and are a part of, this Agreement in their entirety; such provisions will
continue to apply as if they were set forth in this Agreement.

<PAGE>   20

   reference in the Registration Statement and the Prospectus do not comply as
   to form in all material respects with the applicable accounting requirements
   of the Act, the Exchange Act and the related published rules and regulations
   thereunder and Staff Accounting Bulletins with respect to registration
   statements on Form S-2 and the Exchange Act documents and filings
   incorporated by reference therein or such unaudited consolidated financial
   statements are not fairly presented in conformity with generally accepted
   accounting principles applied on a basis substantially consistent with that

  specified procedures, not constituting an audit, they have compared certain
  specified amounts, percentages and financial information included in the
  Registration Statement and the Prospectus, in Exhibits 11 and 12 to the
  Registration Statement or in the Company's Quarterly Reports on Form 10-Q for
  the fiscal quarters ended March 31, 1995, June 30, 1995 and September 30,
  1995 incorporated by reference in the Registration Statement and Prospectus
  with the underlying accounting records of the Company and its consolidated
  subsidiaries and with information derived from such records and have found
  them to be in agreement, excluding any questions of legal interpretation.

   (e)   If the letters referred to in paragraph (d) above set forth any such
changes, decreases or increases, it shall be a further condition to the
obligations of the Underwriters that (1) such letters shall be accompanied by a
written explanation of the Company as to the significance thereof, unless the
Underwriters deem such explanation unnecessary, and (2) such changes, decreases
or increases do not, in the sole judgment of the Underwriters, make it
impractical or inadvisable to proceed with the purchase and delivery of the
Debentures as contemplated by the Registration Statement.  References to the

(e) with respect to the letters referred to above shall include any amendment

their respective directors, officers, partners, agents and employees and each
other person, if any, who controls any Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act (collectively,
"Indemnitees") against any losses, claims, damages or liabilities, joint or
several, to which such Indemnitee may become subject under the Act, the
Exchange Act or





                                       22

<PAGE>   23

otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of, relate to, or are caused by or based upon:

     (1)  any untrue statement or alleged untrue statement made by the Company
  in this Agreement,

     (2)  any untrue statement or alleged untrue statement of any material fact
  contained in (A) the Registration Statement or any amendment thereto or any
  Preliminary Prospectus or the Prospectus or any amendment or supplement
  thereto or (B) any application or other document, or any amendment or
  supplement thereto, executed by the Company or based upon written information
  furnished by or on behalf of the Company filed in any jurisdiction in order
  to qualify the Securities under the securities or blue sky laws thereof or
  filed with the Commission or any securities association or securities
  exchange (each an "Application"),

     (3)  any omission or alleged omission to state in the Registration
  Statement or any amendment thereto, any Preliminary Prospectus or the
  Prospectus or any amendment or supplement thereto, or any Application a
  material fact required to be stated therein or necessary to make the
  statements therein, in light of the circumstances under which they were made,
  not misleading, or

     (4)  any untrue statement or alleged untrue statement of any material fact
  contained in any audio or visual materials prepared by the Company and used
  in connection with the marketing of the Securities, including, without
  limitation, slides, videos, films, and tape recordings,

and will reimburse, as incurred, each Indemnitee for any legal or other
expenses reasonably incurred by such Indemnitee in connection with
investigating, defending against, or appearing as a third-party witness in
connection with, any such loss, claim, damage, liability or action; provided,
however, that the Company will not be liable in any such case to the extent
that any such loss, claim, damage or liability arises out of, is related to, or
is caused by or based upon, any untrue statement or alleged untrue statement or
omission or alleged omission made in such Registration Statement or any
amendment thereto, any Preliminary Prospectus, the Prospectus or any amendment
or supplement thereto, or any Application in reliance upon, and in conformity
with, written information furnished to the Company by any Underwriter expressly
for use therein; and provided, further, that the Company will not be liable to
any Indemnitee with respect to any such untrue statement or omission made in
any Preliminary Prospectus that is corrected in the Prospectus (or any
amendment or supplement thereto) if the person asserting any such loss, claim,
damage or liability purchased Debentures from such Underwriter but was not sent
or given a copy of the Prospectus (as amended or supplemented), other than the
documents incorporated by reference therein, at or prior to the written
confirmation of the sale of such Debentures to such person in any case where
such delivery of the Prospectus (as amended or supplemented) is required by the
Act and where delivery of such Prospectus (as amended or supplemented) would





                                       23

<PAGE>   24

have cured the defect giving rise to such loss, claim, damage or liability,
unless such failure to deliver the Prospectus (as amended or supplemented) was
a result of noncompliance by the Company with Section 5(d) or 5(e) of this
Agreement.  This indemnity agreement will be in addition to any liability which
the Company may otherwise have.  The Company will not, without the prior
written consent of the Underwriters, settle or compromise or consent to the
entry of any judgment in any pending or threatened claim, action, suit or
proceeding in respect of which indemnification may be sought hereunder (whether
or not any such Indemnitee is a party to such claim, action, suit or
proceeding), unless (1) such settlement, compromise or consent includes an
unconditional release of all of the Indemnitees from all liability arising out
of such claim, action, suit or proceeding and (2) the entire settlement amount
and all costs of settlement and all related costs are borne by the Company.

   (b)   The Company hereby expressly and irrevocably waives any and all rights
and objections which it may have against any Indemnitee in respect of any
liabilities arising out of, or relating to, this Agreement or the offering
contemplated by this Agreement, except to the extent such liabilities are
determined, by a final order of a court of competent jurisdiction, to be the
direct and primary result from the Underwriters' gross negligence or willful
misconduct.  Each Underwriter, individually and not jointly, will indemnify and
hold harmless the Company, each of its directors, each of its officers who
signed the Registration Statement and each person, if any, who controls the
Company within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act against any losses, claims, damages or liabilities to which the
Company, any such director or officer of the Company, or any such controlling
person of the Company may become subject under the Act, the Exchange Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) are determined, by a final order of a court of competent
jurisdiction, to be the direct and primary result of (1) any untrue statement
or alleged untrue statement of any material fact contained in the Registration
Statement or any amendment thereto, any Preliminary Prospectus or the
Prospectus or any amendment or supplement thereto, or any Application or (2)
the omission or the alleged omission to state therein a material fact required
to be stated in the Registration Statement or any amendment thereto, any
Preliminary Prospectus or the Prospectus or any amendment or supplement
thereto, or any Application, or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such
untrue statement or alleged untrue statement or omission or alleged omission is
determined by such court to have been made in reliance upon, and in conformity
with, written information furnished to the Company by such Underwriter
expressly for use therein; and, subject to the limitation set forth immediately
preceding this clause, will reimburse, as incurred, any legal or other expenses
reasonably incurred by the Company or any such director, officer or controlling
person in connection with investigating, defending against or appearing as a
third party witness in connection with any such loss, claim, damage, liability  
or action.  This indemnity agreement will be in addition to any liability which
such Underwriter may otherwise have.  The Underwriters will not, without the
prior written consent of the Company, settle or compromise or consent to the
entry of any judgment in any pending or threatened claim, action, suit or
proceeding in respect of which indemnification may be sought hereunder (whether
or not any such Indemnitee is a party to such claim, action, suit or
proceeding), unless (1) such settlement, compromise or consent includes an
unconditional release of all of the Indemnitees from all liability arising out
of such claim, action, suit or proceeding and (2) the entire settlement amount
and all costs of settlement and all related costs are borne by the
Underwriters.

   (c)   Promptly after receipt by an indemnified party under this Section 8 of
notice of the commencement of any action (including any governmental
investigation), such indemnified party will, if a claim in respect thereof is
to be made against the indemnifying party





                                       24

<PAGE>   25

under this Section 8, notify the indemnifying party of the commencement of such
action; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under this Section 8 and will not relieve it from any liability under this
Section 8 except to the extent the indemnifying party is actually prejudiced by
the failure to give such notice.  In case any such action is brought against
any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party; provided, however, that if the
parties to any such action (including any impleaded parties) include both the
indemnified party and the indemnifying party or any officers, directors or
controlling persons of such indemnifying party and the indemnified party shall
have reasonably concluded that there may be one or more legal defenses
available to it and/or other indemnified parties which are different from or
additional to those available to the indemnifying party, the indemnifying party
shall not have the right to direct the defense of such action on behalf of such
indemnified party or parties and such indemnified party or parties shall have
the right to select separate counsel to defend such action on behalf of such
indemnified party or parties.  After notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof and approval
by such indemnified party of counsel appointed to defend such action, the
indemnifying party will not be liable to such indemnified party under this
Section 8 for any legal or other expenses, other than reasonable costs of
investigation, subsequently incurred by such indemnified party in connection
with the defense thereof, unless (1) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence
(it being understood, however, that in connection with such action the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (in addition to local counsel) in any one action or separate
but substantially similar actions in the same jurisdiction arising out of the
same general allegations or circumstances, which counsel shall be designated by
you in the case of indemnification under paragraph (a) of this Section 8 and by
us in the case of indemnification under paragraph (b) of this Section 8,
representing the indemnified parties under such paragraphs (a) or (b), as the
case may be, who are parties to such action or actions) or (2) the indemnifying
party does not promptly retain counsel reasonably satisfactory to the
indemnified party or (3) the indemnifying party has authorized the employment
of counsel for the indemnified party at the expense of the indemnifying party.
After such notice from the indemnifying party to such indemnified party, the
indemnifying party will not be liable for the costs and expenses of any
settlement of such action effected by such indemnified party without the
written consent of the indemnifying party.

   (d)   If the indemnity agreement provided for in the preceding paragraphs of
this Section 8 is unavailable or insufficient, for any reason, to hold harmless
an indemnified party in respect of any losses, claims, damages or liabilities
(or actions in respect thereof), each indemnifying party, in order to provide
for just and equitable contribution, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages
or liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect (1) the relative benefits received by the indemnifying
party or parties on the one hand and the indemnified party on the other from
the offering of the Securities or (2) if the allocation provided





                                       25

<PAGE>   26

by the foregoing clause (1) is not permitted by applicable law, not only such
relative benefits but also the relative fault of the indemnifying party or
parties on the one hand and the indemnified party on the other in connection
with the statements or omissions or alleged statements or omissions that
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations.  The relative
benefits received by the Company on the one hand and the Underwriters on the
other shall be deemed to be in the same proportion as the total proceeds from
the offering (before deducting expenses) received by the Company bear to the
total underwriting discounts and commissions received by the Underwriters, in
each case as set forth on the cover page of the Prospectus.  The relative fault
of the parties shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by
the Company or the Underwriters, the parties' relative intents, knowledge,
access to information and opportunity to correct or prevent such statement or
omission, and any other equitable considerations appropriate in the
circumstances.  The Company and the Underwriters agree that it would not be
equitable if the amount of such contribution were determined by pro rata or per
capita allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take into account
the equitable considerations referred to above in this paragraph (d).
Notwithstanding any other provision of this paragraph (d), no Underwriter shall
be obligated to make contributions under this paragraph (d) that in the
aggregate exceed the total public offering price of the securities purchased by
such Underwriter under this Agreement, less the aggregate amount of any damages
that such Underwriter has otherwise been required to pay in respect of such
untrue or alleged untrue statement or omission or alleged omission, and no
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  The Underwriters' obligations to
contribute under this paragraph (d) are individual in proportion to their
respective underwriting obligations and not joint.  For purposes of this
paragraph (d), each person, if any, who controls an Underwriter within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have
the same rights to contribution as such Underwriter, and each director of the
Company, each officer of the Company who signed the Registration Statement and
each person, if any, who controls the Company within the meaning of Section 15
of the Act or Section 20 of the Exchange Act, shall have the same rights to
contribution as the Company.

  9. Default of Underwriters.  If one of the Underwriters shall fail or refuse
to purchase Firm Debentures or Option Debentures under this Agreement and if
arrangements satisfactory to the non-defaulting Underwriter are not made within
36 hours after such default for the purchase by other persons (who may include
the non-defaulting Underwriter) of the Debentures with respect to which such
default occurs, this Agreement will terminate without liability on the part of
any non-defaulting Underwriter or the Company other than as provided in Section
10 of this Agreement.  In any such case which does not result in the
termination of this Agreement, the non-defaulting Underwriter shall have the
right to postpone the Firm Closing Date or the Option Closing Date, as the case
may be, established as provided in Section 3 of this Agreement for not more
than seven business days in order that any necessary changes may be made in the





                                       26

<PAGE>   27

Registration Statement, the Prospectus, the other documents and the
arrangements for the purchase and delivery of the Firm Debentures or Option
Debentures, as the case may be.  As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 9.  Nothing herein shall relieve any defaulting Underwriter from
liability for its default.

  10.  Survival.  The respective representations, warranties, agreements,
covenants, indemnities, contribution agreements and other statements of the
Company and the several Underwriters set forth in this Agreement or made by or
on behalf of them, respectively, pursuant to this Agreement shall remain in
full force and effect, regardless of (1) any investigation made by or on behalf
of the Company, any of its officers or directors, any Underwriter or any
controlling person referred to in Section 8 of this Agreement and (2) delivery
of and payment for the Securities.  The respective agreements, covenants,
indemnities and other statements set forth in Sections 6 and 8 of this
Agreement shall remain in full force and effect, regardless of any termination
or cancellation of this Agreement.

  11.  Termination.

   (a)   This Agreement may be terminated with respect to the Firm Debentures
or any Option Debentures in your sole discretion by notice to the Company given
prior to the Firm Closing Date or the related Option Closing Date,
respectively, in the event that the Company shall have failed, refused or been
unable to perform all obligations on its part to be performed under this
Agreement on or before the Firm Closing Date or the Option Closing Date, as
applicable, or if any of the conditions in Section 7 shall not have been
fulfilled when and as required by this Agreement to be fulfilled, or if, at or
prior to the Firm Closing Date or such Option Closing Date, respectively:

     (1)  the Company or any of its subsidiaries shall have, in your sole
  judgment, sustained any material loss or interference with their respective
  businesses or properties from fire, flood, hurricane, accident or other
  calamity, whether or not covered by insurance, or from any labor dispute or
  any legal or governmental proceeding or there shall have been any material
  adverse change, or any development involving a prospective material adverse
  change (including without limitation a change in management or control of the
  Company), in the condition (financial or otherwise), management, business,
  net worth, cash flows or results of operations of the Company or any of its
  subsidiaries, except in each case as described in or contemplated by the
  Prospectus (exclusive of any amendment or supplement thereto);

     (2)  trading in the Common Shares shall have been suspended by the
  Commission or The Nasdaq National Market or trading in securities generally
  on the New York Stock Exchange or The Nasdaq National Market shall have been
  suspended or minimum or maximum prices shall have been established on such
  exchange or market system;





                                       27

<PAGE>   28
     (3)  a banking moratorium shall have been declared by Michigan, New York
  or United States authorities;

     (4)  there shall have been (A) an outbreak or escalation of hostilities
  between the United States and any foreign power, (B) an outbreak or
  escalation of any other insurrection or armed conflict involving the United
  States or (C) any other calamity or crisis or material adverse change in the
  general economic, political or financial conditions having an effect on the
  U.S. financial markets that, in your sole judgment, makes it impractical or
  inadvisable to proceed with the public offering or the delivery of the
  Securities as contemplated by the Registration Statement, as amended as of
  the date of this Agreement;

     (5)  the shall have been enacted, published, decreed or promulgated any
  federal, state or local statute, regulation, rule or order of any court or
  other governmental authority which in your opinion materially and adversely
  affects or will materially and adversely affect the business or operations of
  the Company; or

     (6)  any actions shall have been taken by any federal, state or local
  government or agency in respect of its monetary or fiscal affairs which in
  your opinion has a material adverse effect on the securities markets in the
  United States.

   (b)   Termination of this Agreement pursuant to this Section 11 shall be
without liability of any party to any other party except as provided in Section
6 (including the provisions of the Letter of Intent which are incorporated in
this Agreement) and Section 8 of this Agreement.

  12.  Information Supplied by Underwriters.  The statements set forth in the
last paragraph on the front cover page and under the heading "Underwriting" in
any Preliminary Prospectus or the Prospectus (to the extent such statements
relate to the Underwriters) constitute the only information furnished by any
Underwriter to the Company for the purposes of Section 8 of this Agreement.
The Underwriters confirm that such statements (to such extent) are correct.

  13.  Notices.  All communications under this Agreement shall be in writing
and delivered or sent by mail, telex or facsimile transmission and confirmed in
writing as follows:

representatives, and nothing expressed or mentioned in this Agreement is
intended or shall be construed to give any other person any legal or equitable
right, remedy or claim under or in respect of this Agreement, or any provisions
contained in this Agreement, this Agreement and all conditions and provisions
of this Agreement being intended to be and being for the sole and exclusive
benefit of such persons and for the benefit of no other person except that (i)
the indemnities of the Company contained in Section 8 of this Agreement shall
also be for the benefit of the Indemnitees, including, without limitation, any
person or persons who control any Underwriter within the meaning of Section 15
of the Act or Section 20 of the Exchange Act and (ii) the indemnities of the
Underwriters contained in Section 8 of this Agreement shall also be for the
benefit of the directors of the Company, the officers of the Company who have
signed the Registration Statement and any person or persons who control the
Company within the meaning of Section 5 of the Act or Section 20 of the
Exchange Act.  No purchaser of Securities from any Underwriter shall be deemed
a successor because of such purchase.

  15.  Applicable Law.  The validity and interpretation of this Agreement, and
the terms and conditions set forth in this Agreement, shall be governed by and
construed in accordance with the laws of the State of Michigan, without giving
effect to any provisions relating to conflicts of laws.

counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

each of the Underwriters.

                                Very truly yours,

or opinion need be furnished.

         Every Officers' Certificate or Opinion of Counsel with respect to
compliance with a condition or covenant provided for in this Indenture (other
than certificates provided pursuant to Section 314(a)(4) of the Trust Indenture
Act) shall include:

         (a)     a statement that each individual signing such Officers'
Certificate or Opinion of Counsel has read such covenant or condition and the
definitions herein relating thereto;

         (b)     a brief statement as to the nature and scope of the
examination or investigation upon which the statements or opinions contained in
such Officers' Certificate or Opinion of Counsel are based;

         (c)     a statement that, in the opinion of each such individual, he
or she has made such examination or investigation as is necessary to enable him
or her to express an informed opinion as to whether or not such covenant or
condition has been complied with; and

         (d)     a statement as to whether, in the opinion of each such
individual, such condition or covenant has been complied with.

         Section 1.3      Form of Documents Delivered to Trustee.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

         Any certificate or opinion of any officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his or her certificate or opinion is
based are erroneous.  Any certificate or Opinion of Counsel may be based,
insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
such matters are erroneous.

         In the event that any Person is required to make, give or execute two
or more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

         Section 1.4      Acts of Holders; Record Dates.

         (a)     Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent
duly appointed in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are
delivered to the Trustee, and, if it is hereby expressly required, to the
Company.  Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments.  Proof of execution of such instrument
or of a writing appointing any such agent shall be sufficient for any purpose
of this Indenture and, subject to Section 6.1, conclusive in favor of the
Trustee and the Company, if made in the manner provided in this Section.

         (b)     The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer
authorized by law to take acknowledgement of deeds, certifying that the
individual signing such instrument or writing acknowledgement to him or her the
execution thereof.  Where such execution is by a signer acting in a capacity
other than his or her individual capacity, such certificate or affidavit shall
also constitute sufficient proof of his or her authority.  The fact and date of
the execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other manner that the Trustee
deems sufficient.

         (c)     The ownership of Debentures shall be proved by the Debenture
Register.

         (d)     Any request, demand, authorization, direction, notice,
consent, waiver or other Act by the Holder of any Debenture shall bind every
future Holder of the same Debenture and the Holder of every Debenture issued
upon the transfer thereof or in exchange therefor or in lieu thereof, in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made
upon such Debenture.

         Without limiting the foregoing, a Holder entitled hereunder to give or
take any action hereunder with regard to any particular Debenture may do so
with regard to all





                                       12
<PAGE>   19

or any part of the principal amount of such Debenture or by one or more duly
appointed agents each of whom may do so pursuant to such appointment with
regard to all or any different part of such principal amount.

         Section 1.5      Notices, etc., to Trustee and Company.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

         (a)     the Trustee by any Holder shall be sufficient for every
purpose hereunder if made, given, furnished or filed in writing to or with the
Trustee at its principal Corporate Trust Office.

         (b)     the Trustee by the Company shall be sufficient for every
purpose hereunder (unless otherwise herein expressly provided) if in writing
and mailed, first class postage prepaid, to the Trustee addressed to it at the
Corporate Trust Office, or

         (c)     the Company by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and mailed, first class postage prepaid, to the Company
addressed to it to the attention of its Treasurer at the address of its
principal office specified in the first paragraph of this instrument or at any
other address previously furnished in writing to the Trustee by the Company.

         Section 1.6      Notices to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his or her address as it appears in the Debenture Register,
not later than the latest date, and not earlier than the earliest date, if any,
prescribed for the giving of such notice.  In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in
any notice so mailed, to any particular Holder shall affect the sufficiency of
such notice with respect to other Holders.  In any case where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice.  Waivers of notice by
Holders shall be filed with the Trustee, but such filing shall not be a
condition precedent to the validity of any action taken in reliance upon such
waiver.





                                       13
<PAGE>   20

         In case, by reason of the suspension of regular mail service, or by
reason of any other cause, it shall be impractical to give such notice by mail
as required by this Indenture, then such notification as shall be made with the
approval of the Trustee shall constitute a sufficient notification for every
purpose hereunder.

         Section 1.7      Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with the duties
imposed by any of Sections 310 through Section 317, inclusive, of the Trust
Indenture Act through the operation of Section 318(c) thereof, such imposed
duties shall control.

         Section 1.8      Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction thereof.

         Section 1.9      Successors and Assigns.

         All covenants and agreement in this Indenture by the Company shall
bind its successors and assigns, whether or not so expressed.

         Section 1.10     Separability Clause.

         In case any provision in this Indenture or in the Debentures shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions hereof or thereof shall not in any way be affected or
impaired thereby.

         Section 1.11     Benefits of Indenture.

         Nothing in this Indenture or in the Debentures, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder, the holders of Senior Indebtedness and the Holders, any benefit or
any legal or equitable right, remedy or claim under this Indenture.

         Section 1.12     Governing Law.

         This Indenture and the Debentures shall be governed by and construed
in accordance with the laws of the State of Michigan, but without regard to
principles of conflicts of laws.

         Section 1.13     Limitation on Liability of Company Officers.

         No recourse shall be had for the payment of the principal, interest or
premium, if any, on the Debentures or for any claim based thereon or otherwise
in respect thereof or based on or in respect of this Indenture against any
shareholder, officer, director, agent or employee of the Company.

         Section 1.14     Counterparts.

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all of such
counterparts shall together constitute but one and the same instrument.

          The Debentures and the certificates of authentication thereon shall
be in substantially the form set forth in Exhibit A, with such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture and may have such letters, numbers or other marks

consistently herewith, be determined by the officers executing such Debentures,
as evidenced by their execution of the Debentures.  Any portion of the text of
any Debenture may be set forth on the reverse thereof, with an appropriate
reference thereto on the face of the Debenture.

         The definitive Debentures shall be printed, lithographed or engraved

such other manner as the Company may deem appropriate, all as determined by the
officers executing such Debentures, as evidenced by their execution of such
Debentures.

                                 THE DEBENTURES

         Section 3.1      Title and Terms.

         The aggregate principal amount of Debentures which may be
authenticated and delivered under this Indenture is limited to $11,500,000,
except for Debentures authenticated and delivered upon transfer of, or in
exchange for, or in lieu of other Debentures pursuant to Sections 3.4, 3.5,
3.6, 8.5, 10.7 and 11.2.

         The Debentures shall be known and designated as the ___% Convertible
Subordinated Debentures Due December 1, 2002 of the Company.  The Debentures
shall bear interest from the date and at the rate per annum and such interest
shall be payable on the dates, specified in the form of Debenture set forth in
Exhibit A, until the principal thereof is paid or made available for payment.

         All interest payments to be made to registered Holders of Debentures
shall be paid directly by the Company to the Trustee, and, unless otherwise
arranged by the Company with the concurrence of the Trustee, the Trustee shall
mail those interest payments to the Holders that are listed in the Debenture
Register by the Interest Payment Date.  The principal of and premium, if any,
on the Debentures shall be payable at the office or agency of the Company
maintained pursuant to Section 9.5 for such purposes in Boston, Massachusetts,
or at such other office or agency as may be established by the Company.

         The Debentures shall be convertible as provided in Article 11.

         The Debentures shall be subordinated in right of payment to Senior
Indebtedness of the Company as provided in Article 12.

         Section 3.2      Denominations.

         The Debentures shall be issuable only in fully registered form,

                                       16
<PAGE>   23

         Section 3.3      Execution, Authentication, Delivery and Dating.

         The Debentures shall be executed on behalf of the Company by its
Chairman, President or a Vice President and attested by its Secretary,
Treasurer, or one of its Assistant Secretaries or Assistant Treasurers.  The
signature of any of these officers on the Debentures may be manual or
facsimile.

         Debentures bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Debentures or did not
hold such offices at the date of such Debentures.

         Upon the original issuance of the Debentures by the Company and
authentication by the Trustee, the Trustee shall deliver the Debentures to the
Holders.

         All Debentures authenticated for original issuance by the Company to
the initial purchaser thereof shall be dated as of their respective Date of
Issue.  All Debentures authenticated for any other purpose hereunder shall be
dated the date of their authentication.

         No Debenture shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose, unless there appears on such Debenture
a certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Debenture has been duly authenticated and delivered hereunder.

         Section 3.4      Temporary Debentures.

         Pending the preparation of definitive Debentures, the Company may
execute and upon Company Order the Trustee shall authenticate and deliver,
temporary Debentures which are printed, lithographed, typewritten, mimeographed
or otherwise produced in any denomination, substantially of the tenor of the
definitive Debentures in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Debentures may determine, as evidenced by their
execution of such Debentures.

         If temporary Debentures are issued, the Company will cause definitive
Debentures to be prepared without unreasonable delay.  After the preparation of
definitive Debentures, the temporary Debentures shall be exchangeable for
definitive Debentures upon surrender of the temporary Debentures at the office
or agency or the





                                       17
<PAGE>   24

Company designated for such purpose pursuant to Section 9.5, without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Debentures, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Debenture of
authorized denominations.  Until so exchanged the temporary Debentures shall in
all respects be entitled to the same benefits under this Indenture as
definitive Debentures.

         Section 3.5      Registration, Transfer and Exchange.

         The Company shall cause to be kept at the Corporate Trust Office of
the Trustee (or at any other office or agency maintained by the Company
pursuant to Section 9.5) a register (herein sometimes referred to as the
"Debenture Register") in which, subject to such reasonable regulations as it
may prescribe, the Company shall provide for the registration of Debentures and
of transfers of Debentures.  The Trustee is hereby initially appointed
"Debenture Registrar" for the purpose of registering Debentures and transfers
of Debentures as herein provided.

         The Holder may surrender the Debentures for transfer at the Corporate
Trust Office or at such other office or agency of the Company designated for
such purpose pursuant to Section 9.5.  The Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Debentures of any authorized
denominations, of a like aggregate principal amount.

         At the option of the Holder, Debentures may be exchanged for other
Debentures of any authorized denominations, of a like aggregate principle
amount, upon surrender of the Debentures to be exchanged at such office or
agency.  Whenever any Debentures are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Debentures
which the Holder making the exchange is entitled to receive.

         All Debentures issued upon any transfer or exchange of Debentures
shall be the valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Debentures
surrendered upon such transfer or exchange.

         Every Debenture presented or surrendered for transfer or exchange
shall, if so required by the Company or the Trustee, be duly endorsed or be
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Debenture Registrar, duly executed by the Holder thereof or by
his or her attorney duly authorized in writing.





                                       18
<PAGE>   25

          No service charge shall be made for any transfer or exchange of
Debentures by any Holder, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any transfer or exchange of Debentures, other than exchanges
pursuant to Sections 3.4, 8.5, 10.7 or 11.2 not involving any transfer.

         The Company shall not be required (a) to issue, transfer or exchange
any Debenture during a period beginning at the opening of business 15 days
before the day of the mailing of a notice of redemption of Debentures selected
for redemption under Section 10.3 and ending at the close of business on the
day of such mailings, or (b) to transfer or exchange any Debenture so selected
for redemption in whole or in part, except for the unredeemed portion of any
Debenture being redeemed in part.

         Section 3.6      Mutilated, Destroyed, Lost and Stolen Debentures.

         If (a) any mutilated Debenture is surrendered to the Trustee, or the
Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Debenture, and (b) there is delivered to the
Company and the Trustee such security or indemnity as may be required by them
to save each of them harmless, then, in the absence of notice to the Company or
the Trustee that such Debenture has been acquired by a bona fide purchaser, the
Company shall execute and upon its request the Trustee shall execute and upon
its request the Trustee shall authenticate and deliver, in exchange for or in
lieu of any such mutilated, destroyed, lost or stolen Debenture, a new
Debenture of like tenor and principal amount, bearing a number not
contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Debenture has
become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Debenture, pay such Debenture.

         Upon the issuance of any new Debenture under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses, including the fees and expenses of the Trustee, connected therewith.

         Every new Debenture issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Debentures shall constitute an original,
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Debenture shall be at any time enforceable by anyone,
and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Debentures duly issued hereunder.





                                       19
<PAGE>   26


         The provisions of this Section are exclusive and shall preclude, to
the extent lawful, all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Debentures.

         Section 3.7      Payment of Interest; Interest Rights Preserved.

         Interest on any Debenture that is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Debenture (or one or more Predecessor Debentures) is registered
at the close of business on the Regular Record Date, which shall be the 15th
day of the month preceding any Interest Payment Date whether or not such day is
a Business Day.

         Any interest on any Debenture that is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date shall accrue from such
Interest Payment Date at a rate per annum that is equal to one percent (1%) per
annum plus the interest rate stated in the Debenture until all unpaid and
accrued interest is paid in full (herein called "Defaulted Interest").  The
Defaulted Interest shall forthwith cease to be payable to the registered Holder
on the relevant Regular Record Date by virtue of having been such Holder; and,
except as hereinafter provided, such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in Section 3.7(a) or 3.7(b)
below:

         (a)     The Company may elect to make payment of any Defaulted
Interest to the Persons in whose name the Debenture (or their respective
Predecessor Debentures) are registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest, which shall be fixed in
the following manner.  The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Debenture and the date
of the proposed payment (which shall be not less than 30 days from such
notice), and at the same time the Company shall deposit with the Trustee an
amount of money equal to the aggregate amount proposed to be paid in respect of
such Defaulted Interest or shall make arrangements satisfactory to the Trustee
for such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as in this Clause provided.  Thereupon the Trustee shall fix
a Special Record Date for the payment of such Defaulted Interest that shall be
not more than 15 nor less than 10 days prior to the date of the proposed
payment and not less than 10 days after the receipt by the Trustee of the
notice of the proposed payment.  The Trustee shall promptly notify the Company
of such Special Record Date and, in the name and at the expense of the Company,
shall cause notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor to be mailed, first class postage prepaid, to each
Holder at his or her address as it appears in the Debenture Register, not less
than 10 days prior to





                                       20
<PAGE>   27

such Special Record Date.  The Trustee may, in its discretion, in the name and
at the expense of the Company, cause a similar notice to be published at least
once in an Authorized Newspaper, but such publication shall not be a condition
precedent to the establishment of such Special Record Date.  Notice of proposed
payment of such Defaulted Interest and of the Special Record Date therefor
having been mailed as aforesaid, such Defaulted Interest shall be paid to the
Persons in whose name the Debentures (or their respective Predecessor
Debentures) are registered on such Special Record Date and shall not longer be
payable pursuant to the following Section 3.7(b).

         (b)     The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Debentures may be listed, and upon such notice as may be
required by such exchange, if, after notice is given by the Company to the
Trustee of the proposed payment pursuant to this Clause, such payment shall be
deemed practicable by the Trustee.

         If any installment of interest which has a Stated Maturity on or prior
to the Redemption Date for any Debentures called for redemption at the election
of the Company or requested to be redeemed by a deceased Holder's authorized
representative pursuant to Article 10 is not paid or duly provided for on or
prior to the Redemption Date in accordance with the foregoing provisions of
this Section, such interest shall be payable as part of the Redemption Price of
such Debentures.

         Subject to the foregoing provisions of this Section, each Debenture
delivered under this Indenture upon transfer of or in exchange for or in lieu
of any other Debenture shall carry the rights to interest accrued and unpaid,
and to accrue, which were carried by such other Debenture.

         All payments of interest on the Debentures to the Persons entitled
thereto, whether made by the Company, the Trustee or any Paying Agent, as
authorized pursuant to this Indenture, shall be made (subject to collection) by
check mailed to the address of the Person entitled thereto, as such address
shall appear on the Debenture Register, unless the Trustee determines such
method of payment to be inappropriate in the circumstances.

         In the case of any Debenture that is converted after any Regular
Record Date and on or prior to the next succeeding Interest Payment Date (other
than any Debenture whose Maturity is prior to such Interest Payment Date),
interest shall be payable on such Interest Payment Date notwithstanding such
conversion, and such interest (whether or not punctually paid or duly provided
for) shall be paid to the Person in whose name that Debenture (or one or more
Predecessor Debentures) is registered at the close of





                                       21
<PAGE>   28

business on such Regular Record Date.  Except as otherwise expressly provided
in the immediately preceding sentence, in the case of any debenture that is
converted, interest after the date of conversion of such Debenture shall not be
payable.

         Section 3.8      Persons Deemed Owners.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name any Debenture is registered as the owner of
such Debenture for the purpose of receiving payment of principal of, and
(subject to Section 3.7) interest on, such Debenture and for all other purposes
whatsoever, whether or not such Debenture is overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

         Section 3.9      Cancellation.

         All Debentures surrendered for payment, conversion, redemption,
transfer or exchange shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and, if not already cancelled, shall be
promptly cancelled by it.  The Company may at any time deliver to the Trustee
for cancellation any Debentures previously authenticated and delivered
hereunder that the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Debentures previously authenticated hereunder that the Company
has not issued and sold, and all Debentures so delivered shall be promptly

determine, to the Persons entitled thereto, of the principal and interest for
whose payment such money has been deposited with the Trustee; but such money

         Section 5.2      Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default occurs and is continuing, then and in every
such case the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Debentures Outstanding may declare the principal amount
of all the Debentures to be due and payable immediately, by a notice in writing
to the Company, and to the Trustee if given by Holders, and upon any such
declaration such principal amount shall become immediately due and payable.

         At any time after such declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article provided, the Holders of 50% in
aggregate principal amount of the Debentures Outstanding, by written notice to
the Company and Trustee, may rescind and annul such declaration and its
consequences if:

         (a)     the Company has paid or deposited with the Trustee a sum 
sufficient to pay

                 (1)      all overdue installments of interest on all
         Debentures,

                 (2)      the principal of (and premium, if any, on) any
         Debentures which have become due (otherwise than by such declaration
         of acceleration) and interest thereon at the rate borne by the
         Debentures,

                 (3)      to the extent that payment of such interest is
         lawful, interest upon overdue installments of interest at the rate
         borne by the Debentures, and

                 (4)      all sums paid or advanced by the Trustee hereunder
         and the reasonable compensation, expenses, disbursements and advances
         of the Trustee, its agents and counsel; and





                                       26
<PAGE>   33


         (b)     all Events of Default, other than the non-payment of the
principal of and premium, if any, and interest on the Debentures that has
become due solely by such acceleration, have been cured or waived as provided
in Section 5.12.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

         Section 5.3      Collection of Indebtedness and Suits for Enforcement
by Trustee.

         The Company covenants that if:

         (a)     default is made in the payment of the principal of (or
premium, if any, on) any Debenture at the Maturity thereof, or

         (b)     default is made in the payment of any installment of interest
on any Debenture when such interest becomes due and payable and such default
continues for a period of 15 days,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Debentures, the whole amount then due and payable on such
Debentures for principal, premium, if any, and interest, with interest upon the
overdue principal and, to the extent that payment of such interest shall be
legally enforceable, upon overdue installments of interest, at the rate borne
by the Debentures; and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

         If the Company fails to pay such amount forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute
a judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon the Debentures and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Debentures, wherever
situated.

         If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other property remedy.

         Section 5.4      Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, conservatorship,
insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment,
composition or other judicial proceeding relative to the Company or relative to
any other obligor upon the Debentures or the property of the Company or of such
other obligor or their creditors, irrespective of whether the principal of the
Debentures shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand
on the Company for the payment of overdue principal or interest, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

         (a)     to file and prove a claim for the whole amount of principal
and interest owing and unpaid in respect of the Debentures, to file such other
papers or documents and to take such other actions as the Trustee may deem
necessary or advisable in order to have the claims of the Trustee, including
any claim for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel, and of the Holders allowed in such
judicial proceeding, and

         (b)     to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any receiver, assignee, trustee, liquidator, sequestrator, or other similar
official, in any such judicial proceeding is hereby authorized by each Holder
to make such payments to the Trustee, and in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 6.7.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Debentures
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

Debentures.

         All rights of action and claims under this Indenture or the Debentures
may be prosecuted and enforced by the Trustee without the possession of any of
the Debentures

<PAGE>   35

or the production thereof in any proceeding relating thereto, and any such
proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Debentures in respect of which such
judgment has been recovered.

         Section 5.6      Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (and premium,
if any) or interest, upon presentation of the Debentures and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

         FIRST:  To the payment of all amounts due the Trustee under Section
6.7;

         SECOND:  In case the principal of the Debentures shall not have become
due, to the payment of interest on the Debentures, in the order of the maturity
of the installments of such interest, with interest, to the extent that such
interest has been collected by the Trustee, upon the overdue installments of
interest at the rate borne by the Debentures, such payments to be made ratably
to the Persons entitled thereto, without discrimination or preference;

         THIRD:  In case the principal of the Debentures shall have become due,
by declaration or otherwise, to the payment of the whole amount then owing and
unpaid upon the Debentures for principal (and premium, if any) and interest,
with interest on the overdue principal (and premium, if any) and, to the extent
that such interest has been collected by the Trustee, upon overdue installments
of interest at the rate borne by the Debentures; and in case such monies shall
be insufficient to pay in full the whole amount so due and unpaid upon the
Debentures, then to the payment of such principal (and premium, if any) and
interest, without preference or priority of principal (and premium, if any), or
of any installment of interest over any other installment of interest, or of
any Debenture over any other Debenture, ratably to the aggregate of such
principal (and premium, if any) and accrued and unpaid interest; and

successors or assigns, or to whomsoever may be lawfully entitled to receive the

request and offer of indemnity has failed to institute any such proceeding; and

         (e)     no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of a majority in

shall have any right in any manner whatever by virtue of, or by availing of,
any provision of this Indenture to affect, disturb or prejudice the rights of
any other Holders of Debentures, or to obtain or to seek to obtain priority or
preference over any other Holders or to enforce any right under this Indenture,
except in the manner herein provided and for the equal and ratable benefit of
all the Holders of Debentures.

shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

         Section 5.10     Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Debenture
to exercise any right or remedy accruing upon any Event of Default shall impair

remedy under this Indenture, or in any suit against the Trustee for any action
taken or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may

         The Company covenants, to the extent that it may lawfully do so, that
it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any usury, stay or extension law
wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of this Indenture; and the Company, to the extent

act on the part of any of the parties hereto.  In case any Debentures shall
have been authenticated, but not delivered, by the Trustee then in office, any

the same effect as if such successor Trustee had itself authenticated such
Debentures.

         Section 9.2      Payment of Taxes and Other Claims.

         The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (a) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary and (b)
all lawful claims for labor, materials and supplies which, if unpaid, might by
law become a lien upon the property of the Company or any Subsidiary; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

         Section 9.3      Company Existence.

         Subject to Section 9.4, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence,
its rights (charter and statutory) and its franchises; provided, however, that
the Company shall not be required to preserve any right or franchise, if the
Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that net effect of
the loss thereof is not disadvantageous in any material respect to the Holders.

         Section 9.4      Company May Consolidate, etc. Only on Certain Terms.

         The Company shall not, and shall not allow any Subsidiary to,
consolidate with or merge into any other Person or convey, transfer or lease
all or substantially all its properties and assets to any Person, and the
Company shall not, and shall not allow any Subsidiary to, permit any Person to
consolidate with or merge into the Company (or any Subsidiary) or convey,
transfer or lease all or substantially all its properties and assets to the
Company (or any Subsidiary), unless:

         (a)     in case the Company (or, if applicable, Subsidiary) shall
consolidate with or merge into another Person or convey, transfer or lease all
or substantially all its properties and assets to any Person, the Person formed
by such consolidation or into which the Company (or Subsidiary) is merged or
the Person that acquires by conveyance or transfer or lease all or
substantially all the properties and assets of the Company (or Subsidiary)
shall be a corporation, partnership or trust organized and validly existing
under the laws of the United States of America, any state thereof or the
District of Columbia and shall expressly assume, by an indenture supplemental
hereto, executed and delivered to the Trustee, in form reasonably satisfactory
to the Trustee, the due and punctual payment of the principal of and any
premium and interest on all





                                       45
<PAGE>   52

the Debentures, the performance or observance of every covenant of this
Indenture on the part of the Company to be performed or observed and every
other obligation of the Company under this Indenture and shall have provided
for conversion rights in accordance with Article 11;

         (b)     immediately after giving effect to such transaction and
treating any Indebtedness that becomes an obligation of the Company or
Subsidiary as a result of such transaction as having been incurred by the
Company or such Subsidiary at the time of such transaction, no Event of
Default, and no event that, after such notice or lapse of time or both, would
become an Event of Default, shall have happened and be continuing;

         (c)     if, as a result of any such consolidation or merger or such
conveyance, transfer or lease, properties or assets to the Company (or
Subsidiary) would become subject to a mortgage, pledge, lien, security interest
or other encumbrance that would not be permitted by this Indenture, the Company
or such successor Person, as the case may be, shall take such steps as shall be
necessary effectively to secure the Debentures equally and ratably with (or
prior to) all Indebtedness secured thereby; and

         (d)     the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger, conveyance, transfer or lease and, if a supplemental indenture is
required in connection with such transaction, such supplemental indenture
comply with this Article and that all conditions precedent herein provided for
relating to such transaction have been complied with.

         Upon any consolidation of the Company with, or merger of the Company
into, any other Person or any conveyance, transfer or lease of all or
substantially all of the properties and assets of the Company in accordance
with this Section, the successor Person formed by such consolidation or into
which the Company is merged or to which such conveyance, transfer or lease is
made shall succeed to, and be substituted for, and may exercise every right and
power of, the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein, and thereafter, except
in the case of a lease, the predecessor Person shall be relieved of all
obligations and covenants under this Indenture and the Debentures.

         Section 9.5      Maintenance of Office or Agency.

         The Company will maintain an office or agency where Debentures may be
presented or surrendered for payment, where Debentures may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Company in respect of the Debentures and this Indenture may be served.  The
office of





                                       46
<PAGE>   53

Boston Financial Data Services in Boston, Massachusetts shall be such office or
agency of the Company, unless the Company shall designate and maintain some
other office or agency for one or more of such purposes.  The Company will give
prompt written notice to the Trustee of any change in the location of any such
office or agency.  If at any time the Company shall fail to maintain any such
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at
the Corporate Trust Office, and the Company hereby appoints the Trustee as its
agent to receive all such presentations, surrenders, notices and demands.

         Section 9.6      Money for Debenture Payments to be Held in Trust.

         If the Company shall at any time act as its own Paying Agent with
respect to the Debentures, it will, on or before each due date of the principal
or any premium or interest on the Debentures, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum sufficient to pay the
principal and any premium and interest so becoming due until such sums shall be
paid to such Persons or otherwise disposed of as herein provided and will
promptly notify the Trustee of its action or failure so to act.

         Whenever the Company shall utilize a Paying Agent for the Debentures,
it will, prior to each due date of the principal of or any premium or interest
on the Debentures, deposit with the Paying Agent a sum sufficient to pay such
amount, such sum to be segregated and held in trust for the benefit of the
Persons entitled thereto, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

         The Company will cause the Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will (a) comply with the provisions of this Indenture
applicable to it as a Paying Agent and (b) during the continuance of any
default by the Company in the making of any payment in respect of the
Debentures, and upon the written request of the Trustee, forthwith pay to the
Trustee all sums held in the trust by such Paying Agent for payment in respect
of the Debentures.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held
in trust by the Company or such Paying Agent; and, upon such payment by any
Paying Agent to the Trustee, such Paying Agent shall be released from all
further liability with respect to such money.





                                       47
<PAGE>   54

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or any premium or
interest on any Debenture and remaining unclaimed for two years after such
principal, premium or interest has become due and payable shall be paid to the
Company on Company Request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Debenture shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such
trust money; provided, however, that the Trustee or such Paying Agent, before
being required to make any such repayment, may at the expense of the Company
cause to be published once, in an Authorized Newspaper, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication, any unclaimed balance of
such money then remaining will be repaid to the Company.

         Section 9.7      Statement by Officers as to Default.

         The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers
thereof the Company is in default in the performance and observance of any of
the terms, provisions and conditions of this Indenture (without regard to any
period of grace or requirement of notice provided hereunder) and, if the
Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge.

         Section 9.8      Maintenance of Properties.

         The Company will:

         (a)     cause its properties and the properties of its Subsidiaries
used or useful in the conduct of the business of the Company and its
Subsidiaries to be maintained and kept in good condition, repair and working
order and supplied with all necessary facilities and equipment and will cause
to be made all necessary repairs, renewals, replacements, betterments, and
improvements thereof, all as in the judgment of the Company may be necessary so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however that nothing in this
Subsection shall prevent the Company or a Subsidiary from discontinuing the
operation and maintenance of any of its properties if such discontinuation is,
in the judgment of the Company, desirable in the conduct of its business and
not disadvantageous in any material respect to the Holders, and





                                       48
<PAGE>   55

         (b)     take all appropriate steps to preserve, protect and maintain
the trademarks, trade names, copyrights, licenses and permits used in the
conduct of the business of the Company and its Subsidiaries; provided, however,
that nothing in this Subsection shall prevent the Company or a Subsidiary from
selling, abandoning or otherwise disposing of any such trademark, trade name,
copyright, license or permit if such sale, abandonment or disposition is, in
the judgment of the Company, desirable in the conduct of its business and not
disadvantageous in any material respect to the Holders.

         Section 9.9      Purchase of Debentures upon a Repurchase Event.

         (a)     If there shall have occurred a Repurchase Event, the Company
shall make an offer to purchase all the Outstanding Debentures.  Such offer
shall expire on a date that is not earlier than 45 days nor later than 60 days
from the date the Repurchase Event Notice referred to below is mailed to
Holders or such later date as may be necessary for the Company to comply with
requirements under the Exchange Act (such date, or such later date, being the
"Repurchase Date"), at a purchase price in cash (the "Repurchase Price") equal
to 101% of the principal amount of such Debentures, plus accrued and unpaid
interest (including any Defaulted Interest), if any, to the Repurchase Date,
subject to satisfaction by or on behalf of the Holder of the requirements set
forth in this Section 9.9.

         (b)     Within 30 days after the occurrence of a Repurchase Event, the
Company shall give written notice of such Repurchase Event (a "Repurchase Event
Notice") and of its offer (the "Repurchase Offer") to purchase Debentures as
specified herein to the Trustee, and to each Holder of the Debentures at his
address appearing on the Debenture Register, by first-class mail, postage
prepaid.  The Trustee shall be under no obligation to ascertain the occurrence
of a Repurchase Event.  The Repurchase Event Notice shall contain all
instructions and materials necessary to enable such Holders to tender
Debentures, shall include a form of Repurchase Notice (as defined in Section
9.9(c)) to be completed by the Holder and shall state:

                 (1)      the events causing the Repurchase Event and the date
         such Repurchase Event is deemed to have occurred for purposes of this
         Section 9.9, accompanied by a description of any material developments
         in the Company's business since the latest annual or quarterly report
         filed with the Trustee and, if material, any appropriate pro forma
         financial information;

                 (2)      the date by which a Holder must give a Repurchase
         Notice;

                 (3)      the Repurchase Price;





                                       49
<PAGE>   56

                 (4)      the Repurchase Date;

                 (5)      that any Debenture not purchased will continue to
         accrue interest;

                 (6)      that Debentures accepted for payment shall, on the
         Repurchase Date, become due and payable at the Repurchase Price and
         from and after such date (unless the Company shall default in the
         payment of the Repurchase Price) such Debentures shall cease to accrue
         interest; and

                 (7)      the procedures a Holder must follow to exercise
         rights under this Section 9.9 and a brief description of those rights
         and the procedures for withdrawing a Repurchase Notice.

         (c)     A Holder may exercise its rights specified in Section 9.9(a)
upon (1) delivery to the Trustee of a written notice (a "Repurchase Notice") at
any time prior to the close of business on the Repurchase Date, stating (A) the
certificate number of the Debenture that the Holder will deliver to be
purchased and (B) the portion of the principal amount of the Debenture that the
Holder will deliver to be purchased, which portion must be $1,000 or an
integral multiple thereof and (2) delivery, within the time limits specified in
the Repurchase Event Notice, of such Debenture to such Paying Agent at such
office (together with all necessary endorsements) and a copy of the Repurchase
Notice, such delivery being a condition to receipt by the Holder of the
Repurchase Price therefor.  If a Holder has elected to deliver to the Company
for purchase a portion of a Debenture, and if the principal amount of such
portion is $1,000 or an integral multiple of $1,000, the Company shall purchase
such portion from the Holder thereof pursuant to this Section 9.9.  Provisions
of this Indenture that apply to the purchase of all of a Debenture also apply
to the purchase of a portion of such Debenture.  The Trustee shall promptly
notify the Company of the receipt by the former of any and all Repurchase
Notices and any and all written notices of withdrawal thereof.

         (d)     Upon receipt by any Paying Agent of a Repurchase Notice, the
Holder of the Debenture in respect of which such Repurchase Notice was given
shall (unless such Repurchase Notice is validly withdrawn pursuant to Section
9.9(i)) thereafter be entitled to receive solely the Repurchase Price with
respect to such Debenture.  Such Repurchase Price shall be paid to such Holder
promptly following the later of the Business Day following the Repurchase Date
(provided the conditions in Section 9.9(c) have been satisfied) and the time of
delivery of such Debenture to the relevant Paying Agent at the office of such
Paying Agent by the Holder thereof in the manner required by Section 9.9(c).





                                       50
<PAGE>   57

         (e)     On or prior to the Repurchase Date, the Company shall deposit
with the Trustee an amount of money in same day funds sufficient to pay the
Repurchase Price of all the Debentures or portion thereof which are to be
purchased on that date.

         (f)     Upon a Repurchase Notice having been given as aforesaid,
Debentures validly tendered, not withdrawn and accepted for payment shall, on
the Repurchase Date, become due and payable at the Repurchase Price and from
and after such date (unless the Company shall default in the payment of the
Repurchase Price) such Debentures shall cease to bear interest.  Upon surrender
of any such Debenture for purchase in accordance with the foregoing provisions,
such Debenture shall be paid by the Company at the Repurchase Price; provided,
however, that installments of interest whose Stated Maturity is on or prior to
the Repurchase Date shall be payable to the Holders of such Debentures, or one
or more Predecessor Debentures, registered as such on the relevant Regular
Record Dates.  If any Debenture tendered for purchase shall not be paid in
accordance with the provisions of this Section 9.9 upon surrender thereof, the
principal thereof (and premium, if any, thereon) shall, until paid, bear
interest from the Repurchase Date at the rate borne by such Debenture.

         (g)     Any Debenture that is to be purchased only in part shall be
surrendered to a Paying Agent at the office of such Paying Agent (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or such Holder's attorney duly authorized in writing),
and the Company shall execute and the Trustee shall authenticate and deliver to
the Holder of such Debenture, without service charge, one or more new
Debentures of any authorized denomination as requested by such Holder in an
aggregate principal amount equal to, and in exchange for, the portion of the
principal amount of the Debenture so surrendered that is not purchased.

         (h)     The Company shall comply with applicable tender offer rules,
including Rule 14e-1 under the Exchange Act, in connection with a Repurchase
Offer and may modify a Repurchase Offer to so comply.

         (i)     A Repurchase Notice may be withdrawn before or after delivery
by the Holder to the Trustee by means of a written notice of withdrawal (by
facsimile transmission or letter) received by the Trustee at the office of the
Trustee not later than three Business Days prior to the Repurchase Date,
specifying, as applicable:

                 (1)      the certificate number of the Debenture with respect
         of which such notice of withdrawal is being submitted;





                                       51
<PAGE>   58

                 (2)      the principal amount of the Debenture with respect to
         which such notice of withdrawal is being submitted;
         and

                 (3)      the principal amount, if any, of the Debenture that
         remains subject to the original Repurchase Notice and that has been or
         will be delivered for purchase by the Company.

         Each Paying Agent will promptly return to the prospective Holders
thereof any Debentures with respect to which a Repurchase Notice has been
withdrawn in compliance with this Indenture.

         Section 9.10     Waiver of Certain Covenants.

         Without limiting the rights of the Holders and the Company with
respect to waivers and amendments set forth in Section 5.12 and 8.2 the Company
may omit in any particular instance to comply with any covenant or condition
set forth in Sections 9.2 through 9.4, if before or after the time for such
compliance the Holders of at least a majority in aggregate principal amount of
the Debentures at the time Outstanding shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such covenant or condition shall remain in full
force and effect.

                            REDEMPTION OF DEBENTURES

         Section 10.1     Right of Redemption by Company.

         The Company may, at its option, redeem all or any part of the
Debentures at any time prior to December 1, 1998 if the Closing Price per share
of the Company's Common Stock has equalled or exceeded 140% of the then
effective Conversion Price per share of Common Stock for at least 20 Trading
Days within 30 consecutive Trading Days ending not more than ten Trading Days
prior to the date of a notice of redemption.  Such redemption will be in cash
and will be at the Redemption Prices set forth in the Debentures together with
accrued interest (including any Defaulted Interest) to the Redemption Date.
The Debentures are subject to redemption by the Company, at its option, at any
time on or after December 1, 1998 at the Redemption Prices set forth





                                       52
<PAGE>   59

in the Debentures, together with accrued interest (including any Defaulted
Interest) to the Redemption Date.

         Section 10.2     Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Debentures shall be
evidenced by a Board Resolution.  In case of any redemption at the election of
the Company of all or less than all of the Debentures, the Company shall, at
least 60 days prior to the Redemption Date (unless a shorter notice shall be
satisfactory to the Trustee) notify the Trustee of such Redemption Date and of
the principal amount of Debentures to be redeemed.

         Section 10.3     Selection by Trustee of Debentures to be Redeemed 
                          at the Election of the Company.

         If less than all the Debentures are to be redeemed at the election of
the Company, the particular Debentures to be redeemed shall be selected not
more than 45 days prior to the Redemption Date by the Trustee, from the
Outstanding Debentures not previously called for redemption, by such method as
the Trustee shall deem fair and appropriate and that may provide for the
selection for redemption of portions (equal to $1,000 or any integral multiple
thereof) of the principal of Debentures of a denomination larger than $1,000.
If any Debenture selected for partial redemption is converted in part before
the termination of the conversion right resulting from such selection, the
converted portion of such Debenture shall be deemed (so far as may be possible)
to be the portion selected for redemption.  Debentures that have been converted
during a selection of Debentures to be redeemed shall be treated by the Trustee
as Outstanding for the purposes of such selection.

         The Trustee shall promptly notify the Company in writing of the
Debentures selected for redemption and in the case of any Debentures selected
for partial redemption, the principal amount thereof to be redeemed.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Debentures shall relate,
in the case of any Debenture redeemed or to be redeemed only in part, to the
portion of the principal of such Debenture which has been or is to be redeemed.

         Section 10.4     Notice of Redemption at the Election of the Company.

         Notice of redemption at the election of the Company shall be given by
the Company, or at the Company's request, by the Trustee in the name and at the
expense





                                       53
<PAGE>   60

of the Company by first-class mail, postage prepaid, mailed not less than 30
nor more than 60 days prior to the Redemption Date, to each Holder of
Debentures to be redeemed, at his or her address appearing in the Debenture
Register.

         Each notice of redemption shall state:

         (a)     the Redemption Date,

         (b)     the Redemption Price,

         (c)     if less than all Outstanding Debentures are to be redeemed,
the identification (and, in the case of partial redemption, the respective
principal amounts) of the Debentures to be redeemed,

         (d)     that on the Redemption Date the Redemption Price will become
due and payable upon each such Debenture, and that interest thereon shall cease
to accrue from and after said date,

         (e)     the Conversion Price, the date on which the right to convert
the principal of the Debentures to be redeemed will terminate and the place or
places where such Debentures may be surrendered for conversion,

         (f)     the place or places where such Debentures are to be
surrendered for payment of the Redemption Price, and

         (g)     the CUSIP numbers of the Debentures to be redeemed.

         Section 10.5     Deposit of Redemption Price.

         Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 9.6) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Debentures
that are to be redeemed on that date.  If any Debenture called for redemption
is converted pursuant to Article 11, any money deposited with the Trustee or so
segregated and held in trust for the redemption of such Debenture shall
(subject to the right of the Holder of such Debenture or any Predecessor
Debenture to receive interest as provided in the last paragraph of Section 3.7)
be paid to the Company on Company Request, or if then held by the Company,
shall be discharged from such trust.

         Section 10.6     Debentures Payable on Redemption Date.

         Notice of redemption at the election of the Company having been given
as aforesaid, the Debentures so to be redeemed shall, on the Redemption Date,
become due and payable at the Redemption Price therein specified and from and
after such date, unless the Company shall default in the payment of the
Redemption Price, such Debentures shall cease to bear interest.  Upon surrender
of such Debentures for redemption in accordance with said notice, such
Debentures shall be paid by the Company at the Redemption Price, together with
accrued interest to the Redemption Date.  Installments of interest whose Stated
Maturity is on or prior to the Redemption Date shall be payable to the Holders
of such Debentures, or one or more Predecessor Debentures, registered as such
on the relevant Record Dates according to their terms and the provisions of
Section 3.7.

         If any Debenture called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate borne by the
Debenture.

         Section 10.7     Debentures Redeemed in Part.

         Any Debenture which is to be redeemed only in part shall be
surrendered at a location specified in the notice of redemption with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his or her attorney duly authorized in writing, and
the Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Debenture without service charge, a new Debenture or Debentures,

                            CONVERSION OF DEBENTURES

         Section 11.1     Conversion Privileges and Conversion Price.

         Subject to and upon compliance with the provisions of this Article, at
the option of the Holder thereof, any Debenture or any portion of the principal
amount thereof that is $1,000 or an integral multiple of $1,000 may be
converted at the principal amount thereof, or of such portion thereof, into
fully paid and non-assessable shares (calculated





                                       55
<PAGE>   62

as to each conversion to the nearest 1/100 of a share) of Common Stock of the
Company, at the Conversion Price, determined as hereinafter provided, in effect
at the time of conversion.  Such conversion right shall expire at the close of
business on November 1, 2002.  In case a Debenture or portion thereof is called
for redemption or is repurchased upon the occurrence of a Repurchase Event,
such conversion right in respect of the Debenture or portion so called shall
expire at the close of business on the Redemption Date or the Repurchase Date,
unless the Company defaults in making the payment due upon redemption or
repurchase.

         The price at which shares of Common Stock shall be delivered upon
conversion (herein called the "Conversion Price") shall be initially [$_______]
per share of Common Stock.  Effective [____________, 199_,] this Conversion
Price shall be adjusted from time to time as provided in this Article 11.

         Section 11.2     Exercise of Conversion Privilege.

         In order to exercise the conversion privilege, the Holder of any
Debenture to be converted shall surrender such Debenture, duly endorsed or
assigned to the Company or in blank at any office or agency of the Company
maintained for that purpose pursuant to Section 9.5, accompanied by written
notice to the Company at such office or agency that the Holder elects to
convert such Debenture or, if less than the entire principal amount thereof is
to be converted, the portion thereof to be converted.  Debentures surrendered
for conversion during the period from the close of business on any Regular
Record Date next preceding any Interest Payment Date to the opening of business
on such Interest Payment Date shall (except in the case of Debentures or
portions thereof that have been called for redemption, or are to be
repurchased, on such Interest Payment Date or on a Redemption Date or a
Repurchase Date within the period beginning on such Regular Record Date and
ending on such Interest Payment Date) be accompanied by payment to the Company
by wire transfer or certified check or other funds acceptable to the Company of
an amount equal to the interest payable on such Interest Payment Date on the
principal amount of Debentures being surrendered for conversion.  Subject to
the provisions of Section 3.7 relating to the payment of Defaulted Interest by
the Company, the interest payment with respect to a Debenture called for
redemption on a Redemption Date during the period from the close of business on
any Regular Record Date next preceding any Interest Payment Date to the opening
of business on such Interest Payment Date shall be payable on such Interest
Payment Date to the Holder of such Debenture at the close of business on such
Regular Record Date notwithstanding the conversion of such Debenture after such
Regular Record Date and prior to such Interest Payment Date, and the Holder
converting such Debenture need not include a payment of such interest payment
amount upon surrender of such Debenture for conversion.  Except as provided in
the preceding sentence and





                                       56
<PAGE>   63

subject to the final paragraph of Section 3.7, no payment or adjustment shall
be made upon any conversion on account of any interest accrued on the
Debentures surrendered for conversion or on account of any dividends on the
Common Stock issued upon conversion.

         Debentures shall be deemed to have been converted immediately prior to
the close of business on the day of surrender of such Debentures for conversion
in accordance with the foregoing provisions, and at such time the rights of the
Holder of such Debentures as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time.  As promptly as practicable on or after the conversion date, the Company
shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 11.3.

         In the case of any Debenture that is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Debenture
or Debentures of authorized denominations in aggregate principal amount equal
to the unconverted portion of the principal amount of such Debenture.

         Section 11.3     Fractional Shares.

         No fractional shares of Common Stock shall be issued upon conversion
of Debentures.  If more than one Debenture shall be surrendered for conversion
at one time by the same Holder, the number of full shares that shall be
issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Debentures (or, specified portions thereof)
so surrendered.  Instead of any fractional share of Common Stock that would
otherwise be issuable upon conversion of any Debenture or Debentures (or,
specified portions thereof), the Company shall pay a cash adjustment in respect
of such fraction in an amount equal to the same fraction of the Closing Price
on the last Trading Day prior to the date of conversion.

         Section 11.4     Adjustment of Conversion Price.

         The Conversion Price shall be adjusted from time to time as follows:

         (a)     In case the Company shall (i) pay a dividend or make a
distribution in shares of its Common Stock; (ii) subdivide its outstanding
Common Stock into a greater number of shares, or (iii) combine its outstanding
Common Stock into a smaller number





                                       57
<PAGE>   64

of shares, the Conversion Price in effect immediately prior thereto shall be
adjusted so that the Holder of any Debenture thereafter surrendered for
conversion shall be entitled to receive the number of shares of Common Stock of
the Company which he would have owned or have been entitled to receive after
the happening of any of the events described above had such Debenture been
converted immediately prior to the happening of such event.  An adjustment made
pursuant to this subsection (a) shall become effective immediately after the
record date in the case of a dividend or distribution and shall become
effective immediately after the effective date in the case of subdivision or
combination.

         (b)     In case the Company shall issue rights or warrants to all
holders of its Common Stock entitling them (for a period expiring within 45
days after the record date mentioned below) to subscribe for or purchase Common
Stock at a price per share less than the current market price per share of
Common Stock (as defined in subsection (d) below) at the record date for the
determination of shareholders entitled to receive such rights and warrants, the
Conversion Price in effect immediately prior thereto shall be adjusted so that
the same shall equal the price determined by multiplying the Conversion Price
in effect immediately prior to the date of issuance of such rights and warrants
by a fraction of which the numerator shall be the number of shares of Common
Stock  outstanding on the date of the issuance of such rights or warrants plus
the number of shares which the aggregate offering price of the total number of
shares so offered would purchase at such current market price, and of which the
denominator shall be the number of shares of Common Stock outstanding on the
date of issuance of such rights or warrants plus the number of additional
shares of Common Stock offered for subscription or purchase.  Such adjustment
shall be made successively whenever any such rights or warrants are issued, and
shall become effective immediately after such record date.  In determining
whether any rights or warrants entitle the holder to subscribe for or purchase
shares of Common Stock at less than such current market price, and in
determining the aggregate offering price of such shares of Common Stock, there
shall be taken into account any consideration received by the Company for such
rights or warrants, the value of such consideration, if other than cash, to be
determined by the Board of Directors.

         (c)     In case the Company shall distribute to all holders of its
Common Stock and securities of the Company (other than Common Stock) or
evidences of its indebtedness or assets (excluding cash dividends or
distributions paid from retained earnings of the Company) or any rights or
warrants to subscribe for or purchase any of its securities (excluding those
referred to in subsection (b) above, then in each such case the Conversion
Price shall be adjusted so that the same shall equal the price determined by
multiplying the Conversion Price in effect immediately prior to the date of
such distribution by a fraction of which the numerator shall be the current
market price per





                                       58
<PAGE>   65

share (as defined in subsection (d) below) of the Common Stock on the record
date mentioned below less the then fair market value (as determined by the
Board of Directors of the Company, whose determination shall be conclusive, and
described in a certificate filed with the Trustee) of the capital stock or
assets or evidences of indebtedness so distributed or of such rights or
warrants applicable to one share of Common Stock and the denominator shall be
the current market price per share (as defined in subsection (d) below) of the
Common Stock.  Such adjustment shall become effective immediately after the
record date for the determination of shareholders entitled to receive such
distribution.

         (d)     For the purpose of any computation under subsections (b) and
(c) above, the current market price per share of the Common Stock at any date
shall be deemed to be the average of the closing prices for the twenty
consecutive Trading Days next preceding the day in question.  The closing price
for each day shall be (i) the last reported sale price of the Common Stock on
the National Market of the National Association of Securities Dealers, Inc.,
Automated Quotation System, or any similar system of automated dissemination of
quotations of securities prices then in common use, if so quoted, or (ii) if
not quoted as described in clause (i), the mean between the higher bid and low
asked quotations for the Common Stock as reported by the National Quotation
Bureau Incorporated if at least two securities dealers have inserted both bid
and asked quotations for the Common Stock on at least 5 of the 10 preceding
days, or (iii) if the Common Stock is listed or admitted for trading on any
national securities exchange, the last sale price, or the closing bid price if
no sale occurred, of the Common Stock on the principal securities exchange on
which the Common Stock is listed.  If the Common Stock is quoted on a national
securities or central market system, in lieu of a market or quotation system
described above, the closing price shall be determined in the manner set forth
in clause (ii) of the preceding sentence if bid and asked quotations are
reported but actual transactions are not, and in the manner set forth in clause
(iii) of the preceding sentence if actual transactions are reported.  If none
of the conditions set forth above is met, the closing price of the Common Stock
on any day or the average of such closing price for any period shall be the
fair market value of the Common Stock as determined by a member firm of the New
York Stock Exchange, Inc. selected by the Company.

         (e)     No adjustment in the Conversion Price shall be required unless
such adjustment would require an increase or decrease of at least 1% in such
price; provided, however, that any adjustments which by reason of this
subsection (e) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment.  All calculations under this Article
11 shall be made to the nearest cent or to the nearest one hundredth of a
share, as the case may be.  Anything in this Section 11.4 to the contrary
notwithstanding, the Company shall be entitled to make such





                                       59
<PAGE>   66

reductions in the Conversion Price, in addition to those required by this
Section 11.4, as it in its discretion shall determine to be advisable in order
that any stock dividends, subdivision of shares, distribution of rights to
purchase stock or securities, or a distribution of securities convertible into
or exchangeable for stock hereafter made by the Company to its shareholders
shall not be taxable.

         (f)     In any case in which this Section 11.4 provides that an
adjustment shall become effective immediately after a record date for an event,
the Company may defer until the occurrence of such event (i) issuing to the
Holder of any Debenture converted after such record date and before the
occurrence of such event the additional shares of Common Stock issuable upon
such conversion by reason of the adjustment required by such event over and
above the Common Stock issuable upon such conversion before giving effect to
such adjustment and (ii) paying to such Holder any amount in cash in lieu of
any fractional share pursuant to Section 11.3.

         (g)     The Trustee shall not be responsible for any calculation made
under this section.

         Section 11.5     Notice of Adjustments of Conversion Price.

         Whenever the Conversion Price is adjusted as herein provided:

         (a)     the Company shall compute the adjusted Conversion Price in
accordance with Section 11.4 and shall prepare a certificate signed by the
Treasurer of the Company setting forth the adjusted Conversion Price and
showing in reasonable detail the facts upon which such adjustment is based, and
such certificate shall forthwith be delivered to the Trustee and filed at each
office or agency maintained for the purpose of conversion of Debentures
pursuant to Section 9.5; and

         (b)     a notice setting forth that the Conversion Price has been
adjusted and setting forth the adjusted Conversion Price shall forthwith be
prepared by the Company and mailed to all Holders of Debentures at their last
addresses as they shall appear in the Debenture Register.

         Section 11.6     Notice of Certain Corporation Action.

         In case:

         (a)     the Company shall declare a dividend (or any other
distribution) on its Common Stock payable otherwise than in cash out of its
retained earnings; or





                                       60
<PAGE>   67

         (b)     the Company shall authorize the granting to the holders of its
Common Stock generally of rights or warrants to subscribe for or purchase any
shares of Capital Stock of any class or of any other rights; or

         (c)     of any reclassification of the Common Stock of the Company
(other than a subdivision or combination of its outstanding shares of Common
Stock), or of any consolidation or merger to which the Company is a party and
for which approval of any shareholders of the Company is required, or of the
sale or transfer of all or substantially all of the assets of the Company; or

         (d)     of the voluntary or involuntary dissolution, liquidation or
winding up of the Company; or

         (e)     the Company or any subsidiary shall commence a tender offer
for all or a portion of the Company's outstanding shares of Common Stock (or
shall amend any such tender offer);

then the Company shall notify the Trustee and cause to be filed at each office
or agency maintained for the purpose of conversion of Debentures pursuant to
Section 9.5, and shall cause to be mailed to all Holders of Debentures at their
last addresses as they shall appear in the Debenture Register, at least 20 days

on which such reclassification, consolidation, merger, sale, transfer,
liquidation or winding up is expected to become effective, and the date on

dissolution, liquidation or winding up, or (z) the date on which such tender
offer commenced, the date on which such tender offer is scheduled to expire
unless extended, the consideration offered and the material terms thereof (or

         Section 11.8 Taxes on Conversion.

         The Company will pay any and all taxes, other than any franchise or
income taxes, that may be payable in respect of the issue or delivery of stock
certificates representing shares of Common Stock on conversion of Debentures

that may be payable in respect of any transfer involved in the issue and
delivery of shares of Common Stock in a name other than that of the Holder of
the Debenture or Debentures to be converted, and no such issue or delivery
shall be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax, or has established to the satisfaction of
the Company that such tax has been paid.

         Section 11.9     Covenant as to Common Stock.

         The Company covenants that all shares of Common Stock that may be

         Section 11.10  Cancellation of Converted Debentures.

                        Share Exchange or Sale.

         If any of the following event occur, namely (i) any reclassification
or change of outstanding shares of Common Stock issuable upon conversion of the
Debentures (other than a change in par value, or from par value to no par
value, or from no par value to par value, or as a result of a subdivision or
combination), (ii) any consolidation or merger of the Company with another

securities or other property or assets (including cash) with respect to or in
exchange for such Common Stock or (iii) any sale or conveyance of all or
substantially all of the properties and assets of the Company to any other

providing that each Debenture shall be convertible into the kind and amount of
shares of stock and other securities or property or assets (including cash)
receivable upon such reclassification, change,





                                       62
<PAGE>   69

consolidation, merger, sale or conveyance by a holder of a number of shares of
Common Stock issuable upon conversion of such Debentures immediately prior to
such reclassification, change, consolidation, merger, statutory share exchange,
sale or conveyance.  Such supplemental indenture shall provide adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article.  The Company shall cause notice of the execution
of such supplemental indenture to be mailed to each Holder of Debentures, at
his address appearing on the Debenture Register.

         The above provisions of this Section shall similarly apply to

                          SUBORDINATION OF DEBENTURES

         Section 12.1     Agreement to Subordinate.

         The Company covenants and agrees, and each Holder of Debentures, by
his or her acceptance thereof, likewise covenants and agrees, that the
Indebtedness represented by the Debentures and the payment of the principal of
and premium, if any, and interest on each and all of the Debentures are hereby
expressly subordinated, to the extent and in the manner hereinafter set forth,
in right of payment to the prior payment in full of all Senior Indebtedness as
provided in this Article 12.

         Section 12.2     No Payment on Securities in Certain Circumstances.

         Unless Section 12.3 shall be applicable, after the occurrence of a
default in the payment of the principal of, premium, if any, or interest on any
Senior Indebtedness, no payment or distribution  of any assets of the Company
or of any Subsidiary of any kind or character shall be made by the Company or
the Trustees on account of or with respect to the Debentures, whether of
principal, premium, if any, or interest thereon, or on account of the purchase,
redemption, defeasance or other acquisition of Debentures, unless and until
such payment default shall have been cured or waived or shall have ceased to
exist, or such Senior Indebtedness shall have been discharged or paid in full
in cash, after which the Company shall resume making any and all required
payments in respect of the Debentures, including any missed payments.

         Section 12.3     Debentures Subordinated to Prior Payment of All
Senior Indebtedness on Dissolution, Liquidation or Reorganization.

         Upon any distribution of assets of the Company upon any dissolution,
winding-up, liquidation or reorganization of the Company (pursuant to or
following bankruptcy, insolvency, reorganization or receivership proceedings),
or upon an assignment for the benefit of creditors or any other marshalling of
the asserts and liabilities of the Company,

         (a)     the holders of all Senior Indebtedness shall first be entitled
to receive payment in full of the principal thereof and premium, if any, and
interest due thereon, or adequate provision shall be made for such payment,
before the Holders of the Debentures are entitled to receive any payment on
account of the principal of, premium, if any, or interest on indebtedness
evidenced by the Debentures; and

         (b)     any payment by, or distribution of assets of, the Company of
any kind or character, whether in cash, property or securities, to which the
Holders of the Debentures or the Trustee would be entitled except for the
provision of this Article 12 shall be paid or delivered by the Person making
such payment or distribution, whether a trustee in bankruptcy, a receiver or
liquidating trustee or otherwise, directly to the holders of Senior
Indebtedness or their representative or to the trustee of trustees under any
indenture under which any instruments evidencing any of such Senior
Indebtedness may have been issued, ratably according to the aggregate amounts
remaining unpaid on account of the Senior Indebtedness held or represented by
each, to the extent necessary to make payment in full of all Senior
Indebtedness remaining unpaid after giving effect to any concurrent payment or
distribution to the holders of such Senior Indebtedness or provision thereof.

         Section 12.4     Payments by Trustee or Holders to Holders of Senior
                          Indebtedness.

         In the event that any payment by, or distribution of assets of, the
Company of any kind or character, whether in cash, property or securities,
shall be received by the Trustee or the Holders of the Debentures before all
Senior Indebtedness is paid in full, contrary to the provisions of Sections
12.2 or 12.3, such payment or distribution shall be paid over to the holders of
such Senior Indebtedness or their representative or representatives or to the
trustee or trustees under any indenture under which any instruments evidencing
any of such Senior Indebtedness may have been issued, ratably as aforesaid, for
application to the payment of all Senior Indebtedness remaining unpaid until
all such Senior Indebtedness shall have been paid in full, after giving effect
to any concurrent payment or distribution to the holders of such Senior
Indebtedness or provision therefor.

         Section 12.5     Subrogation.

         Subject to the payment in full of all Senior Indebtedness, the Holders
of the Debentures shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of cash, property or
securities of the Company applicable to the Senior Indebtedness until all
amounts owing on the Debentures shall be paid in full, and, as between the
Company, its creditors other than holders of Senior Indebtedness, and the
Holders of the Debentures, no such payment or distribution made to the holders
of Senior Indebtedness by virtue of this Article 12 which otherwise would have
been made to the Holders of the Debentures shall be deemed to be a payment by
the Company on account of the Senior Indebtedness, it being understood that the
provisions of this Article 12 are and are intended solely for the purpose of
defining the relative rights of the Holders of the Debentures, on the one hand,
and the holders of Senior Indebtedness, on the other hand.

         Section 12.6     Obligations of Company Unconditional.

         Nothing contained in this Article 12 or elsewhere in this Indenture or
in the Debentures is intended to or shall impair, as between the Company, its
creditor other than the holders of Senior Indebtedness, and the Holders of the
Debentures, the obligation of the Company, which is absolute and unconditional,
to pay to the Holders of the Debentures the principal of and any premium and
interest on the Debentures as and when the same shall become due and payable in
accordance with their terms, or affect the relative rights of the Holders of
the Debentures and creditors of the Company other than the holders of Senior
Indebtedness, nor shall anything herein or therein prevent the Trustee or the
Holder of any Debenture from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if
any, under this Article 12 of the holders of Senior Indebtedness in respect of
cash, property or securities of the Company received upon the exercise of any
such remedy.

         Upon any payment or distribution of assets of the Company referred to
in this Article 12, the Trustees and the Holders of the Debentures shall be
entitled to rely upon any order or decree made by any court of competent
jurisdiction in which any such dissolution, winding-up, liquidation or
reorganization proceeding affecting the affairs of the Company is pending or
upon a certificate of the liquidating trustee or agent or other Person making
any payment or distribution to the Trustee or to the Holders of the Debentures
for the purpose of ascertaining the Persons entitled to participate in such
payment or distribution, the holders of the Senior Indebtedness and other
Indebtedness of the Company, the amount thereof or payable thereon, the amount
paid or distributed therein and all other facts pertinent thereto or to this
Article 12.

         Section 12.7     Payments on Debentures Permitted.

         Nothing contained in this Article 12 or elsewhere in this Indenture,
or in any of the Debentures, shall affect the obligation of the Company to
make, or prevent the Company from making, at any time except during the
pendency of any dissolution, winding-up, liquidation or reorganization
proceeding, payments at any time of principal of and any premium and interest
on the Debentures.

         Section 12.8     Effectuation of Subordination by Trustee.

         Each Holder of Debentures, by his or her acceptance thereof,
authorizes and directs the Trustee on such Holder's behalf to take such action
as may be necessary or appropriate to effectuate the subordination provided in
this Article 12 and appoints the Trustee such Holder's attorney-in-fact for any
and all such purposes.

         Section 12.9     Knowledge of Trustee.

         Notwithstanding the provisions of this Article 12 or any other

         Code-Alarm, Inc., a corporation duly organized and existing under the

                                CODE-ALARM, INC.

          __% CONVERTIBLE SUBORDINATED DEBENTURE DUE DECEMBER 1, 2002

         This Debenture is one of a duly authorized issue of Debentures of the
Company designated as its ___% Convertible Subordinated Debentures due December
1, 2002 (herein called the "Debentures"), limited in aggregate principal amount
to $11,500,000 issued and to be issued under an Indenture dated as of October
_, 1995 (herein called the "Indenture"), between the Company and State Street
Bank and Trust Company, as Trustee (herein called the "Trustee," which term
includes any successor Trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights thereunder of the Company, the Trustee and the Holders of the
Debentures, and the terms upon which the Debentures are, and are to be,
authenticated and delivered.

         The indebtedness evidenced by this Debenture is, to the extent
provided in the Indenture, subordinate and subject in right of payment to the
prior payment in full of all Senior Indebtedness, and this Debenture is issued
subject to the provisions of the Indenture with respect thereto.  Each Holder
of a Debenture, by acceptance hereof, (a) agrees to and shall be bound by such
provisions of the Indenture and all other provisions of the Indenture; (b)
authorizes and directs the Trustee to take such action on his or her behalf as
may be necessary or appropriate to acknowledge or effectuate, as between the
Holders and the holders of the Senior Indebtedness, the subordination of this
Debenture as provided in the Indenture; and (c) appoints the Trustee his or her
attorney-in-fact for any and all such purposes.  Each Holder of this Debenture,
by accepting the same, agrees that each holder of Senior Indebtedness, whether
created or acquired before or after the issuance of the Debentures, shall be
deemed conclusively to have relied on such provisions in acquiring and
continuing to hold such Senior Indebtedness.

         The Debentures are subject to redemption prior to December 1, 1998 at
the option of the Company at any time upon not less than 30 nor more than 60
days' notice by first class mail, as a whole or in part, only if the Closing
Price per share of the Company's Common Stock has equalled or exceeded 140% of
the then effective Conversion Price per share of Common Stock for at least 20
Trading Days within 30 consecutive Trading Days ending not more than ten
Trading Days prior to the date of a notice of redemption.  On or after December
1, 1998 the Debentures are subject to redemption at any time upon not less than
30 nor more than 60 days' notice by first class mail, as a whole or in part, at
the election of the Company.  Any redemption




                                      3

payment will be made in cash and will be at the Redemption Prices (expressed as

and thereafter at a Redemption Price equal to 100% of the principal amount,
together in the case of any such redemption with accrued interest to the
Redemption Date.

         If less than all Debentures are redeemed, the Trustee will select the
Debentures to be redeemed by such method as the Trustee may deem appropriate
and fair.

         If this Debenture (or a portion thereof) is duly called for redemption
and funds for payment duly provided, this Debenture (or such portion thereof)
shall cease to bear interest from and after such Redemption Date.

         Interest installments with a Stated Maturity on the Redemption Date
will be payable to the Holders of such Debentures, or one or more Predecessor
Debentures, of record at the close of business on the relevant Record Date
referred to on the face hereof, all as provided in the Indenture.  In the event
of redemption or repayment of this Debenture in part only, a new Debenture or
Debentures for the unredeemed or unpaid portion hereof shall be issued in the
name of the Holder hereof upon the cancellation hereof.

         Subject to and upon compliance with the provisions of the Indenture,
the Holder of this Debenture is entitled, (a) at his or her option, at any time
on or before the close of business on December 1, 2002, or (b) in case this
Debenture or a portion hereof is called for redemption or is repurchased upon
the occurrence of a Repurchase Event, then in respect of this Debenture or such
portion hereof until and including, but (unless the Company defaults in making
the payment due upon redemption or repurchase, as the case may be) not after,
the close of business on the Redemption Date or the Repurchase Date, to convert
this Debenture (or any portion of the principal amount





                                      4
<PAGE>   78

hereof which is $1,000 or an integral multiple thereof), at the principal
amount hereof, or such portion, into fully paid and non-assessable shares
(calculated as to each conversion to the nearest 1/100 of a share) of Common
Stock of the Company at a Conversion Price equal to $____ aggregate principal
amount of Debentures for each share of Common Stock (or at the then-current
adjusted Conversion Price if an adjustment has been made as provided in the
Indenture) by surrender of this Debenture, duly endorsed or assigned to the
Company or in blank, to the Company at its office or agency in Boston,
Massachusetts accompanied by written notice to the Company that (i) the Holder
hereof elects to convert this Debenture, or if less than the entire principal
amount hereof is to be converted, the portion hereof to be converted, and (ii)
the name or names (with addresses) in which the certificate shall be issued.
In case such surrender shall be made during the period from the close of
business on any Regular Record Date next preceding any Interest Payment Date to
the opening of business on such Interest Payment Date (unless this Debenture or
the portion thereof being converted has been called for redemption, or is to be
repurchased, on such Interest Payment Date or on a Redemption Date or a
Repurchase Date within such period), this Debenture shall also be accompanied
by payment in the form of a certified check or other funds acceptable to the
Trustee of an amount equal to the interest payable on such Interest Payment
Date on the principal amount of this Debenture then being converted.  Subject
to the aforesaid requirement for payment and, in the case of a conversion after
the Regular Record Date next preceding any Interest Payment Date and on or
before such Interest Payment Date, to the right of the Holder of this Debenture
(or any Predecessor Debenture) of record at such Regular Record Date to receive
an installment of interest (with certain exceptions provided in the Indenture),
no payment or adjustment is to be made on conversion for interest accrued
hereon or for dividends on the Common Stock issued on conversion.  No fractions
of shares or scrip representing fractions of shares will be issued on
conversion, but instead of any fractional interest the Company shall pay a cash
adjustment as provided in the Indenture.  The Conversion Price is subject to
adjustment as provided in the Indenture.  In the case of a consolidation,
merger or statutory share exchange involving the Company as a result of which
holders of Common Stock will be entitled to receive stock, securities or other
property or assets (including cash) with respect to or in exchange for shares
of Common Stock or in the case of a sale or conveyance to another corporation
of all or substantially all the property and assets of the Company, the Holders
of the Debentures then Outstanding will be entitled thereafter to convert such
Debentures into the kind and amount of shares of stock, other securities or
other property or assets which they would have owned or been entitled to
receive upon such consolidation, merger, statutory share exchange, sale or
conveyance had such Debentures been converted to shares of Common Stock
immediately prior to such consolidation, merger, statutory share exchange, sale
or conveyance.

         If an Event of Default as defined in the Indenture shall occur and be
continuing, the principal of all the Debentures may be declared due and payable
in the manner and with the effect provided in the Indenture.  The Indenture
provides that such declaration and its consequences may, in certain events, be
annulled by Holders of a majority in aggregate principal amount of the
outstanding Debentures at the time of such Event of Default.

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Debentures under the Indenture at
any time by the Company with the consent of the Holders of a majority in
aggregate principal amount of the Debentures at the time Outstanding, as
defined in the Indenture.  The Indenture also contains provisions permitting
the Holders of a majority in aggregate principal amount of the Debentures at
the time Outstanding to waive, on behalf of the Holders of all the Debentures,
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences.  Any such consent or
waiver by the Holder of this Debenture shall be conclusive and binding upon
such Holder and upon all future Holders of this Debenture and of any Debenture
issued upon the registration of transfer hereof or in exchange therefor or in
lieu hereof, whether not notation of such consent or waiver is made upon this
Debenture.

         No reference herein to the Indenture and to provisions of this
Debenture or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and any
premium and interest on this Debenture at the times, places and rate, and in
the coin or currency, herein prescribed or to convert this Debenture as
provided in the Indenture.

         As provided in the Indenture and subject to certain limitations
therein set forth, this Debenture is transferable on the Debenture Register of
the Trustee, upon surrender of this Debenture for registration of transfer at
the office or agency of the Trustee to be maintained for that purpose in
Boston, Massachusetts, or at such other office or agency as may be established
by the Company for such purpose pursuant to the Indenture duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Debenture Registrar duly executed by, the Holder hereof or his
or her attorney duly authorized in writing, and thereupon one or more new
Debentures, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

         The Debentures are issuable only in registered form, without coupons,
in denominations of $1,000 and integral multiples thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, Debentures are
exchangeable for a




                                      6
<PAGE>   80

like aggregate principal amount of Debentures of a different authorized
denomination, as requested by the Holder surrendering the same.  No service
charge shall be made for any such transfer or exchange, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Debenture is registered as the owner
hereof for all purposes, whether or not this Debenture be overdue, and neither
the Company, the Trustee, nor any such agent shall be affected by notice to the
contrary.

         The Debenture is unsecured by any collateral, including the assets of
the Company, or any of its Affiliate or Subsidiaries, and is not eligible as
collateral for any loan by the Company.

                               CONVERSION NOTICE
