                               PROSPECTUS SUMMARY


     This summary highlights only selected information contained elsewhere in
this prospectus. Before investing in our common stock, you should read the
entire prospectus carefully, including the "Risk Factors" section and the
financial statements and the notes to those statements.


                                    ROCKFORD


     We are a leading designer, manufacturer and distributor of high-performance
car audio systems. Our car audio products are sold in the worldwide car audio
aftermarket to consumers who want to improve their existing car audio systems.
We market our car audio amplifiers, speakers, source units and accessories under
our Rockford Fosgate brand name. We also sell professional audio products under
our Hafler brand name.



     For nearly 20 years, Rockford Fosgate has been the brand of choice among
our core consumers, 16-24 year old males. We believe our core consumers, part of
the 10-24 year old demographic group known as Generation Y, perceive our
Rockford Fosgate brand as the "coolest" car audio brand. Many of our core
consumers are extremely, almost fanatically, loyal to our Rockford Fosgate
brand, and proudly display our logos on their cars, clothing and even their
bodies.



     We enhance our brand image by using hard-hitting, "in your face" marketing
combined with cutting-edge technology and innovation. We believe our efforts
have generated loyalty among both our core consumers, who devote a significant
portion of their time and disposable income to their car audio systems, and
among the independent retailers who use our brand, products and distinctive
marketing programs to attract Generation Y and other consumers.



     We believe our ability to deliver innovative products to market quickly
appeals to our core consumers' desire for distinctive, "leading edge" products
and powerful, high quality sound. To maintain and further enhance our unique
heritage, we continue to develop new products that are reliable, durable,
technologically advanced and designed to set industry standards in their product
categories. Our Rockford Fosgate and Hafler products have won numerous consumer
and industry awards.



     We believe that total worldwide factory sales of car audio products were
approximately $14.7 billion in 1998, of which $6.3 billion represented
aftermarket sales. The international market for car audio products is more than
twice the size of the U.S. market.



     We currently sell our car audio products in the U.S. through a network of
over 1,500 independent retail stores. Internationally, we sell our car audio
products in over 60 countries through independent distributors and sales
representatives. We distribute our car audio products to consumers primarily
through specialty dealers, audio/video retailers, national consumer electronics
chains and catalog merchants. Historically, specialty dealers have dominated the
retail distribution of car audio aftermarket products.



     Over the last several years, as a result of changing consumer buying
patterns, the audio/ video and consumer electronics retailers have been the
fastest growing distribution channels for car audio products, increasing their
combined market share from 34.5% in 1987 to 50% in 1997. To capitalize on
changing industry dynamics, in early 1999, we began distributing our products
through Best Buy, one of the largest national consumer electronics chains, in
all of its more than 300 stores nationwide.


                                        4

     Our goal is to design, produce and distribute the best engineered and most
recognized and respected brands of high-performance car and professional audio
products in the world. Each element of our strategy is intended to enhance and
reinforce the global brand images of Rockford Fosgate and Hafler among consumers
and retailers. Key elements of our growth strategy are to:


     - Expand Channels of Distribution.  We intend to broaden the distribution
       channels through which we market our products. For example, in August
       1998 we began selling our products to Crutchfield, a car and home audio
       catalog retailer in the U.S., and in early 1999 we began distributing our
       car audio products through Best Buy, a leading consumer electronics and
       car audio retailer. At the same time, we intend to continue our strategy
       of selective distribution, which we believe increases brand loyalty,
       enhances retailers' profit margins and encourages retailers to carry a
       broad range of our products.



     - Develop a Second Brand.  We intend to develop a second brand of car audio
       products to be sold at lower price points. In June 1999, we acquired
       Lightning Audio, a manufacturer and distributor of car audio accessories.
       We intend to introduce a line of moderately priced, high-performance
       amplifiers and subwoofers under the Lightning Audio brand name in 2000.



     - Capitalize on International Opportunities.  We believe the Rockford
       Fosgate brand name is as widely recognized in many foreign countries as
       it is in the U.S. We intend to aggressively expand our marketing efforts
       and strengthen our distribution in order to increase sales of Rockford
       Fosgate, Lightning Audio and Hafler products in international markets.



     - Introduce New and Innovative Products.  We believe our ability to quickly
       deliver innovative products to market appeals to consumers' desire for
       "leading edge" products and provides a significant competitive advantage.
       Our objective is to introduce new products or re-engineer approximately
       one-third of our existing product line annually. We also intend to take
       advantage of the strength of our brand names to expand our product lines.



     - Promote Our Unique Brand Image.  We intend to continue to enhance the
       Rockford Fosgate, Lightning Audio and Hafler brands by projecting an
       image that appeals to consumers who appreciate brand authenticity and
       value.


As a result of our growth strategy, we believe we can significantly grow our
business and become a much larger participant in the $6.3 billion car audio
aftermarket industry worldwide.

                      SUMMARY CONSOLIDATED FINANCIAL DATA
                     (IN THOUSANDS, EXCEPT PER SHARE DATA)


     You should read the following summary consolidated financial data in
conjunction with our financial statements and related notes and with
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" included elsewhere in this prospectus. Set forth below are summary
consolidated statements of operations data for the years ended December 31,
1996, 1997 and 1998 and the six months ended June 30, 1998 and 1999. Also set
forth below is summary consolidated balance sheet data as at June 30, 1999, on
an actual, pro forma and pro forma as adjusted basis. The pro forma data gives
effect to the conversion of $278,953 of the 8.5% convertible subordinated
debentures into 114,236 shares of common stock and to the issuance of 14,424
shares upon exercise of warrants, both to occur upon completion of this
offering. The pro forma as adjusted data gives effect to the sale by us of
2,500,000 shares in this offering at an assumed initial public offering price of
$12 per share, our receipt of the estimated proceeds of that sale after
deducting underwriting discounts and commissions and estimated offering expenses
payable by us, and the application of the net proceeds therefrom. See
"Capitalization."

                                  RISK FACTORS


     Before you invest in our common stock, you should be aware that there are
risks, including those described below. You should consider carefully these risk
factors, together with all of the other information included in this prospectus,
before you decide to purchase shares of our common stock.


THE CAR AUDIO INDUSTRY IS RAPIDLY EVOLVING AND OUR PRODUCTS MAY NOT SATISFY
SHIFTING CONSUMER DEMAND OR COMPETE SUCCESSFULLY WITH COMPETITORS' PRODUCTS.



     Our business is based on the demand for car audio products and our ability
to introduce distinctive new products that anticipate and capitalize upon
emerging technologies and changing consumer demands. If we do not introduce new
products, misinterpret consumer preferences or fail to respond to changes in the
marketplace, consumer demand for our products could decrease and our brand image
could suffer. In addition, our competitors may introduce superior designs or
business strategies, undermining our distinctive image and our products'
desirability. Any of these events could cause our sales to decline.



WE MAY LOSE MARKET SHARE AND ERODE OUR BRAND IMAGE AS WE TRY TO ADAPT TO
CHANGING DISTRIBUTION CHANNELS FOR CAR AUDIO PRODUCTS.


     We must successfully capitalize on new distribution strategies because the
principal distributors of our products are losing market share. We historically
distributed our products primarily through specialty dealers who sold only car
audio products. Over the last several years, specialty dealers have lost market
share to audio/video retailers and large consumer electronics retailers. We
believe this trend is likely to continue and we are now increasing distribution
of our products through these emerging distribution channels. This change in
distribution channels creates significant risks that:

     - We may alienate our specialty dealer base.  Some specialty dealers may
       react to our new strategy by reducing their purchases or even replacing
       our products with competing product lines. Reduced specialty dealer
       loyalty could reduce our market share because specialty dealers continue
       to hold a large share of the market and contribute substantially to our
       brand image among our core consumers; and

     - Our brand image may erode.  Selling in less-specialized distribution
       channels may erode our brand image, which could decrease our product
       prices and profit margins.


Our inability to manage our new distribution channels in a way that mitigates
these risks may reduce our profitability.



ANY DECREASE IN DEMAND FOR OUR AMPLIFIERS OR SPEAKERS COULD SIGNIFICANTLY
DECREASE OUR SALES.



     A significant portion of our future revenue depends upon sales of our
amplifier and speaker products. These two product lines collectively accounted
for approximately 78% of our sales in calendar year 1996, 79% in 1997 and 82% in
1998. If sales of either of these two product lines decline significantly, our
results of operations will be adversely affected.



THE LOSS OF BEST BUY AS A CUSTOMER OR SIGNIFICANT REDUCTIONS IN ITS PURCHASES OF
OUR PRODUCTS WOULD REDUCE OUR SALES.



     Best Buy is a significant customer that we could lose at any time.
Including Best Buy's $4.4 million initial purchase of our products to stock its
distribution channel, Best Buy accounted for 22.7% of our sales for the six
months ended June 30, 1999. We anticipate that Best Buy will continue to account
for a significant portion of our sales for the foreseeable future. Best Buy is
not obligated to any long-term purchases of our products and has

                                        8
<PAGE>   10

considerable discretion to reduce, change or terminate its purchases of our
products. Further, our relationship with Best Buy is recent, as we shipped our
first products to Best Buy in January 1999. We cannot be certain that we will
retain this customer or maintain a relationship as favorable as currently
exists.


WE MAY LOSE MARKET SHARE IF WE ARE NOT ABLE TO COMPETE SUCCESSFULLY AGAINST OUR
CURRENT AND FUTURE COMPETITORS.


     Competition could result in reduced margins on our products and loss of
market share. Our markets are very competitive, highly fragmented, rapidly
changing and characterized by price competition and, in the car audio market,
rapid product obsolescence. Our principal car audio competitors include Alpine,
Clarion, Fujitsu Eclipse, JL Audio, Kicker, MTX, Orion, Panasonic, Phoenix Gold,
Pioneer and Sony. We also compete indirectly with automobile manufacturers, who
may improve the quality of original equipment sound systems, reducing demand for
our aftermarket car audio products, or change the designs of their cars to make
installation of our products more difficult or expensive.

     Some of our competitors have greater financial, technical and other
resources than we do and many seek to offer lower prices on competing products.
To remain competitive, we believe we must regularly introduce new products, add
performance features to existing products and limit increases in prices or even
reduce them.


SEASONALITY OF CAR AUDIO SALES CAUSES OUR QUARTERLY SALES TO FLUCTUATE AND MAY
AFFECT THE TRADING PRICE OF OUR STOCK.


     Our sales are generally greater during the second and third quarters of
each calendar year and lower during the first and fourth quarters, with our
lowest sales typically occurring during the fourth quarter. As a result, after
the announcement of our results of operations for the first and fourth quarters,
our stock price may be lower than at other times of the year. We experience this
seasonality because consumers tend to buy car audio products during the spring
and summer when students are on semester breaks and generally more favorable
weather facilitates installation of our products.


OUR QUARTERLY FINANCIAL RESULTS MAY FLUCTUATE SIGNIFICANTLY, MAKING FINANCIAL
FORECASTING DIFFICULT AND MAKING OUR STOCK PRICE VOLATILE.


     Our quarterly results of operations are difficult to predict and may
fluctuate significantly from quarter to quarter. In some quarters, our operating
results may fall below the expectations of public market analysts and investors.
Our quarterly operating results are difficult to forecast for many reasons, some
of which are outside of our control, including:


     - the level of product, price and dealer competition;



     - size and timing of product orders and shipments, particularly by
       significant customers such as Best Buy;


     - our ability to develop new products and product enhancements that respond
       to changes in technology and consumer needs and preferences while
       controlling costs;


     - weather conditions, which affect our consumers' ability to install our
       products;



     - capacity and supply constraints or difficulties; and



     - timing of marketing programs.


As a result, you should not rely on historical results as an indication of our
future performance. In addition, some of our expenses are fixed and cannot be
reduced in the short term. Accordingly, if sales do not meet our expectations,
our results of operations are likely

                                        9
<PAGE>   11

to be negatively and disproportionately affected. In this event, our stock price
may fall dramatically.


A DECLINE IN DISCRETIONARY SPENDING WOULD LIKELY REDUCE OUR SALES.



     Because car audio sales are highly discretionary, a recession in the
general economy or a general decline in consumer spending would likely have a
material adverse effect on our sales. Consumer spending is volatile and is
affected by certain economic conditions, such as:


     - general business conditions;

     - employment levels, especially among our core consumers;

     - consumer confidence in future economic conditions; and


     - interest and tax rates.



IF WE FAIL TO EXECUTE OUR GROWTH STRATEGY SUCCESSFULLY, OUR FINANCIAL CONDITION
COULD BE SERIOUSLY HARMED.


     Our growth has placed, and our anticipated future growth would continue to
place, a significant strain on our resources and capacity. To manage our growth,
we must:

     - retain and hire skilled, competent employees;

     - continue to improve coordination among our technical, product
       development, manufacturing, sales and financial departments; and

     - maintain our financial, operational and managerial systems and controls.


We cannot be certain that we will achieve our objectives through internal
growth, acquisitions or other means. Acquisitions carry significant risks, since
negotiations of potential acquisitions and their subsequent integration could
divert management's time and resources from our core business. Potential
acquisitions could require us to issue dilutive equity securities, incur debt or
contingent liabilities, amortize goodwill and other intangible expenses or incur
other acquisition-related costs. Further, we may be unable to integrate
successfully any acquisition and we may not obtain the intended benefits of that
acquisition.



IF WE DO NOT CONTINUE TO DEVELOP, INTRODUCE AND ACHIEVE MARKET ACCEPTANCE OF NEW
AND ENHANCED PRODUCTS, OUR SALES MAY DECREASE.


     We must maintain and improve existing products, while successfully
developing and introducing new products, in order to increase sales in current
markets and gain footholds in new markets. Our new and enhanced products must
respond to technological developments and changing consumer needs and
preferences. We may experience difficulties that delay or prevent the
development, introduction or market acceptance of new or enhanced products.
Furthermore, despite extensive testing, we may not be able to detect and correct
defects in our products before we ship them to our customers. This may result in
loss of sales or delays in market acceptance. Even after we introduce them, our
new or enhanced products may not satisfy consumer preferences and product
failures may cause consumers to reject our products. As a result, these products
may not achieve market acceptance. In addition, our competitors' new products
and product enhancements may cause consumers to defer or forego purchases of our
products.


IF WE FAIL TO MANAGE OUR INVENTORY EFFECTIVELY, WE COULD INCUR ADDITIONAL COSTS
OR LOSE SALES.



     Our dealers have many brands to choose from when they decide to order
products and if we cannot deliver products quickly and reliably, they will
likely order from one of our

                                       10
<PAGE>   12

competitors. We must stock enough inventory to fill orders promptly, which
increases our financing requirements and the risk of inventory obsolescence.
Because competition has required us to shorten our product life cycle and more
rapidly introduce new and enhanced products, there is a growing and significant
risk that our inventory could become obsolete.


WE FACE RISKS ASSOCIATED WITH OUR INTERNATIONAL OPERATIONS THAT COULD HARM OUR
FINANCIAL CONDITION.



     The risks inherent in international trade may reduce our international
sales and harm the businesses of our distributors and suppliers. These risks
include:


     - changes in tariff regulations;

     - political instability, war, terrorism and other political risks;

     - foreign currency exchange rate fluctuations;

     - establishing and maintaining relationships with local distributors and
       dealers;

     - lengthy shipping times and accounts receivable payment cycles;

     - import and export licensing requirements;

     - compliance with a variety of foreign laws and regulations, including
       unexpected changes in taxation and regulatory requirements;

     - greater difficulty in safeguarding intellectual property than in the
       U.S.; and

     - difficulty in staffing and managing geographically dispersed operations.


These and other risks may increase the relative price of our products compared
to those manufactured in other countries, reducing the demand for our products.
Beginning in the last six months of 1997 and continuing into 1999, countries in
Asia and Latin America have experienced unstable local economies and significant
devaluations of local currencies. These instabilities may continue or worsen,
which could have a material adverse effect on our business, financial condition,
and results of operations. Our sales in Asia and Latin America, collectively,
constituted 10.7% of total sales for 1998 and 5.2% of sales for the six months
ended June 30, 1999.



LOSS OF AN INTERNATIONAL DISTRIBUTOR MAY DISRUPT OUR SALES.



     International customers accounted for 27.9% of our sales in calendar year
1996, 26.5% in 1997 and 20.1% in 1998. To continue our growth and profitability,
we will need to expand our sales in international markets. We rely on
distributors, each of whom is responsible for one or more countries, to purchase
and resell our products in their territories. When we have disputes with a
distributor, or decide we must change our relationship with a distributor, we
may disrupt the market for our products in that country and lose sales. If we
change a relationship with a distributor, we may repurchase that distributor's
inventory, which would reduce our sales proportionately.



WE MAY INCUR ADDITIONAL COSTS AS WE CHANGE TO A "ONE-STEP" DISTRIBUTION SYSTEM
IN INTERNATIONAL MARKETS.



     Recently, we initiated a strategy of moving to a "one-step" distribution
system in larger markets by converting selected distributors into independent
sales representatives, allowing us to sell directly to retailers. To the extent
we extend this one-step strategy into additional markets, we would incur higher
operating expenses than we would under our current distribution system because
we would be directly responsible for costs such as sales commissions, warranty
costs, bad debt and customer service expenses. We would also have


                                       11
<PAGE>   13


higher working capital requirements and risks than we would under our current
distributor system because we, rather than our distributors, would have to carry
inventory and accounts receivable.



CURRENCY FLUCTUATIONS MAY REDUCE OUR PROFITABILITY OF FOREIGN SALES.



     In early 1999, we began making sales to Canadian and German dealers in
their respective currencies. Previously, all our international sales were
denominated solely in U.S. dollars and, accordingly, we were not directly
exposed to fluctuations in foreign currency exchange rates. An increasing
portion of our international sales will likely be denominated in currencies
other than U.S. dollars, increasing our exposure to gains and losses on foreign
currency transactions. We currently do not trade in derivatives or other
financial instruments to reduce currency risks; however, we attempt to create
"natural" hedges when possible by matching our assets and liabilities in a given
currency. We may not be able to execute this strategy and it may not protect us
in the event of substantial currency fluctuations. We may in the future try to
limit our foreign currency exposure by engaging in more aggressive hedging
strategies.



IF OUR SUPPLY OF COMPONENTS IS INTERRUPTED, WE MAY BE UNABLE TO DELIVER OUR
PRODUCTS TO OUR CUSTOMERS.



     Our manufacturing processes recently have become more dependent on
"just-in-time" suppliers who are globally sourced. Our exposure to supply
restrictions has increased because the just-in-time process does not provide a
backlog of components and materials to satisfy short lead-time orders, to
compensate for potential halts in supply, or to replace components that do not
conform to our quality standards. We do not have any long-term price commitments
from our suppliers and any cost increases may reduce our margins or require us
to raise our prices to protect our margins. We cannot be certain that we could
locate, within reasonable time frames, alternative sources of components and
materials at similar prices and quality levels of our current suppliers. This
failure could result in increased costs, delays to our manufacturing process, an
inability to fill purchase orders on a timely basis and a decrease in product
availability at the retail level. This could cause us to lose sales and damage
our customer relationships.


     Starting in 1999, Hyundai Electronics, a large Korean company, began
supplying us with all of the source units we resell under the Rockford Fosgate
brand name. If Hyundai refuses or is unable to supply source units that meet our
quality standards and specified quantities, we believe we would require a
substantial amount of time to identify and begin receiving source units with
acceptable features and quality from another supplier. During the interim, we
would not have any supply of source units and our sales of source units would be
significantly reduced.


     We rely on Avnet for over 10% of our purchases of electronic components and
parts. If Avnet refuses or is unable to continue to supply us, we would require
substantial time to identify an alternative supplier and could face a shortage
of electronic components and parts.



WE MAY BE UNABLE TO RETAIN AND ATTRACT KEY EMPLOYEES, WHICH COULD IMPAIR OUR
BUSINESS.



     We operate in highly competitive employment markets and cannot guarantee
our continued success in retaining and attracting the employees we need to
develop, manufacture and market our products and manage our operations. Our
business strategy and operations depend, to a large extent, on our senior
management team, particularly Gary Suttle, our President and Chief Executive
Officer. We do not have key-person life insurance on or employment contracts
with any of our key employees, other than Mr. Suttle. The terms of


                                       12
<PAGE>   14


Mr. Suttle's employment contract are limited and if Mr. Suttle or other key
members of our management team are unable or unwilling to continue in their
present positions, our ability to develop, introduce and sell our products could
be negatively impacted.



IF WE ARE UNABLE TO ENFORCE OR DEFEND OUR OWNERSHIP AND USE OF OUR INTELLECTUAL
PROPERTY, OUR BUSINESS MAY DECLINE.



     Our future success will depend, in substantial part, on our intellectual
property. We seek to protect our intellectual property rights, but our actions
may not adequately protect the rights covered by our patents, patent
applications, trademarks and other proprietary rights, and prosecution of our
claims could be time consuming and costly. In addition, the intellectual
property laws of some foreign countries do not protect our proprietary rights as
do the laws of the U.S. Despite our efforts to protect our proprietary
information, third parties may obtain, disclose or use our proprietary
information without our authorization which could adversely affect our business.



     From time to time, third parties have alleged that we infringe their
proprietary rights. In particular, we have exchanged correspondence with
Integrated Electronic Technologies regarding our alleged infringement of patents
held by that company. We believe that our products do not infringe any valid
patents cited in the correspondence. Nonetheless, these claims or similar future
claims could subject us to significant liability for damages, result in the
invalidation of our proprietary rights, limit our ability to use infringing
intellectual property or force us to license third-party technology rather than
dispute the merits of any infringement claim. Even if we prevail, any associated
litigation could be time-consuming and expensive and could result in the
diversion of our time and resources.



OUR SHARES HAVE NEVER BEEN PUBLICLY TRADED, SO WE CANNOT PREDICT THE EXTENT TO
WHICH A TRADING MARKET WILL DEVELOP FOR OUR SHARES.


     This is our initial public offering and there has not been a public market
for our common stock. We cannot predict whether a trading market will develop or
how liquid that market may become. We and the selling shareholders will
establish the initial public offering price based on our negotiations with the
underwriters. That price may not be indicative of the price that will develop in
the trading market.


YEAR 2000 ISSUES MAY CAUSE US TO LOSE SALES, INCREASE OUR COSTS OR DISRUPT OUR
OPERATIONS.


     If our computer and information technology systems, or those of any
material third party, are not Year 2000 compliant, their failure could have a
material adverse effect on our business, financial condition and results of
operations. We may fail to discover Year 2000 compliance problems, even though
we have tested most of our systems and have commenced a survey of our material
suppliers' Year 2000 compliance efforts. If there are compliance problems, our
systems may require substantial revisions or replacements and our third-party
suppliers may not be able to deliver products or services to us.

     In addition, governmental agencies, utility companies, third-party service
providers and others outside our control may not be Year 2000 compliant. This
could result in a systemic failure beyond our control, including, for example, a
prolonged telecommunications or electrical failure, which could also prevent us
from communicating with our customers and manufacturing and shipping our
products. We are engaged in an ongoing Year 2000 assessment and have not
developed any contingency plans over and above our normal business operation
contingency plans. We will take into account the results of our Year 2000
simulation testing and the results of our third-party surveys in determining the
need for, and nature and extent of, any contingency plans. Our inability to
correct a significant Year 2000

                                       13
<PAGE>   15


problem, if one develops, could result in an interruption in, or a failure of,
our normal business activities or operations. Any material Year 2000 problem
could require us to incur significant unanticipated expenses to remedy, could
divert our management's time and attention and could have a material adverse
effect on our business, financial condition and results of operations.



OUR CURRENT SHAREHOLDERS WILL RETAIN CONTROL WHICH MAY LIMIT THE LIQUIDITY AND
MARKET PRICE OF OUR COMMON STOCK.



     After the offering, Mr. Suttle and various shareholders affiliated with or
related to two of our directors, Nicholas G. Bartol and Timothy C. Bartol, will
collectively hold 45.4% of our outstanding shares. These shareholders, if they
act together, will be able to control the outcome of all matters submitted for
shareholder action, including the election of our board of directors and the
approval of significant corporate transactions. Consequently, these shareholders
will effectively control our management and affairs, which may limit the
liquidity of our shares, discourage acquisition bids for Rockford and limit the
price some investors might be willing to pay for our shares.



OUR MANAGEMENT WILL HAVE BROAD DISCRETION IN THE USE OF PROCEEDS FROM THIS
OFFERING AND MAY NOT USE THE PROCEEDS EFFECTIVELY.



     We plan to use approximately $11.5 million of the estimated net proceeds of
the offering for working capital and other general corporate purposes. Our
management will have broad discretion in the use of these proceeds and they may
be used for corporate purposes that do not increase our profitability or market
value. The ineffective use of these proceeds could lead to financial losses and
a drop in our stock price.



YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION.



     If you purchase shares from us in this offering, you will incur immediate
and substantial dilution in pro forma net tangible book value per share of
$7.21. You will pay a price per share which substantially exceeds the value of
our assets after subtracting our liabilities. You and the other investors in
this offering will contribute 89.3% of the total amount paid to us for our
common stock, but will own only 33.9% of our outstanding shares. To the extent
outstanding options or warrants to purchase our shares are exercised, you will
suffer further dilution.



FUTURE SALES OF OUR COMMON STOCK MAY NEGATIVELY AFFECT OUR STOCK PRICE.



     Following this offering, we will have a large number of shares of common
stock outstanding and available for resale immediately and also at various
points in time in the future. Immediately following the completion of this
offering, the holders of a majority of our outstanding shares of common stock
will be limited in their ability to resell their shares either because the
shares are "restricted stock" under securities laws or the shareholders have
entered into lock-up agreements. The market price of our common stock could
decline as a result of sales of a large number of shares in the market following
this offering, or the perception that those sales could occur. If the market
price of our common stock declines it would be more difficult for us to sell
equity securities in the future at a time and price that we deem appropriate.



OUR ANTI-TAKEOVER PROVISIONS COULD AFFECT THE VALUE OF OUR STOCK.



     Our articles of incorporation and bylaws and Arizona law contain provisions
which could discourage potential acquirors from attempting to acquire us. For
example, our board of directors may issue additional shares of common stock to
an investor that supports the incumbent directors in order to make a takeover
more difficult. This could deprive our

                                       14
<PAGE>   16


shareholders of opportunities to sell our stock at above-market prices typical
in many acquisitions.



                           FORWARD-LOOKING STATEMENTS



     This prospectus contains forward-looking statements, including, without
limitation, statements concerning the future of our industry, product
development, business strategy (including the possibility of future
acquisitions), continued acceptance and growth of our products, dependence on
significant customers and suppliers, and the adequacy of our available cash
resources. These statements may be identified by the use of forward-looking
terminology such as "may," "will," "believe," "expect," "anticipate,"
"estimate," "continue" or other similar words. These statements discuss future
expectations, and may contain projections of results of operations or of
financial condition or state other forward-looking information. When considering
forward-looking statements, you should keep in mind the risk factors and other
cautionary statements in this prospectus. The risk factors noted above, and
other factors noted throughout this prospectus, could cause our actual results
to differ significantly from those contained in any forward-looking statement.

                                USE OF PROCEEDS


     The net proceeds to us from the sale of the 2,500,000 shares of common
stock offered by this prospectus are estimated to be $27.1 million, or $32.7
million if the underwriters' over-allotment option is exercised in full, in each
case assuming an initial public offering price of $12.00 per share and after
deducting underwriting discounts and commissions and estimated offering expenses
payable by us. We will not receive any proceeds from the sale of shares of
common stock by the selling shareholders.



     We plan to use the net proceeds from this offering as follows:



     - $15.6 million to fully repay the outstanding balance of our credit
       facility; and



     - $11.5 million for working capital and other general corporate purposes,
       including new product development and marketing expansion. We may also
       use a portion of these proceeds to acquire or invest in complementary
       businesses, products or technologies; however, we have not at this time
       identified a specific acquisition or allocated a specific amount for this
       purpose.



     Pending use of the net proceeds, we plan to invest them in short-term,
interest bearing investment-grade securities.



     Our credit facility consists of a revolving line-of-credit, a term loan and
an equipment financing arrangement. The revolving line-of-credit has a blended
variable interest rate per annum of LIBOR plus 300 basis points and prime plus
75 basis points. The term loan has a fixed interest rate of 10.67% per annum.
The equipment financing arrangement has, at our option three days prior to the
time used, a fixed interest rate per annum based on five-year U.S. Treasury
Notes plus 425 basis points or a variable interest rate per annum based on the
bank's base rate plus 125 basis points. To date, we have not used this equipment
financing arrangement. As at June 30, 1999, the credit facility had a combined
interest rate of 8.31% per annum. The credit facility matures on June 20, 2001.

                                 CAPITALIZATION


     The following table shows our capitalization as at June 30, 1999, on an
actual, pro forma and pro forma as adjusted basis. The pro forma data gives
effect to the conversion of $278,953 of the 8.5% convertible subordinated
debentures into 114,236 shares of common stock and the issuance of 14,424 shares
upon exercise of warrants, both to occur concurrently with this offering. The
pro forma as adjusted data gives effect to:



     - the sale by us of 2,500,000 shares in this offering at an assumed initial
       public offering price of $12.00 per share;



     - our receipt of the estimated proceeds of that sale after deducting
       underwriting discounts and commissions and estimated offering expenses
       payable by us; and



     - the application of the net proceeds.

(1) If we terminate our credit facility after repaying the outstanding balance
    with the proceeds of this offering, we would expense approximately $260,000
    of deferred loan fees included in other assets as at June 30, 1999 which
    were incurred at the time of the loan.

                                    DILUTION


     Our pro forma net tangible book value as at June 30, 1999, after giving
effect to the conversion of $278,953 of the 8.5% convertible subordinated
debentures into 114,236 shares of common stock and the issuance of 14,424 shares
upon exercise of warrants, both to occur upon completion of this offering, was
$8.4 million, or $1.73 per share of common stock. Pro forma net tangible book
value is equal to total pro forma tangible assets less total liabilities. Pro
forma net tangible book value per share is determined by dividing the number of
outstanding shares of common stock into the pro forma net tangible book value.
Our pro forma net tangible book value as at June 30, 1999 would have been $35.3
million, or $4.79 per share, after giving effect to:



     - the sale by us of 2,500,000 shares in this offering at an assumed initial
       public offering price of $12.00 per share;



     - our receipt of the estimated proceeds of that sale after deducting
       underwriting discounts and commissions and estimated offering expenses
       payable by us; and



     - the application of the net proceeds.



This represents an immediate increase in pro forma tangible book value of $3.06
per share to existing shareholders and an immediate dilution of $7.21 per share
to new investors. The following table illustrates this per share dilution:

     The above discussion and table assume no exercise of outstanding
debentures, options and warrants to purchase our common stock other than the
conversion of $278,953 of the 8.5% convertible subordinated debentures and
issuance of 14,424 shares upon exercise of warrants, both to occur upon
completion of this offering. As at June 30, 1999, there were outstanding:



     - 293,123 shares of common stock that we will issue upon conversion of the
       8.5% convertible subordinated debentures, assuming conversion of 114,236
       shares in this offering;



     - 1,995,981 shares of common stock that we will issue upon exercise of
       outstanding options, with a weighted average exercise price of $3.33 per
       share;


                                       18
<PAGE>   20


     - 64,500 shares of common stock that we will issue upon exercise of
       outstanding options, with an exercise price of the per share price of
       this offering; and



     - 83,911 shares of common stock that we will issue upon exercise of
       outstanding warrants, with a weighted average exercise price of $1.25 per
       share.



     We have also reserved 336,984 shares of common stock for future issuance of
options under our 1994 and 1997 stock option plans and 361,200 shares of common
stock for future issuance under our 1999 employee stock purchase plan. To the
extent these dilutive securities are exercised or converted, new investors will
experience further dilution.


                                DIVIDEND POLICY

     We have never paid any cash dividends. We currently intend to retain
earnings, if any, to fund the development and growth of our business and do not
anticipate declaring or paying cash dividends in the foreseeable future. Our
credit facility does not permit the payment of cash dividends. Our board of
directors will decide whether to pay future dividends, if any, at its discretion
taking into account various factors, including our financial condition,
operating results, current and anticipated cash needs and plans for expansion.

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

     The following discussion of our financial condition and results of
operations should be read in conjunction with our consolidated financial
statements and the related notes included elsewhere in this prospectus.

OVERVIEW

     History


     Rockford was incorporated in 1980 to continue a high-performance car audio
business founded in 1973 by car audio enthusiast Jim Fosgate. While Rockford
developed a reputation for technical excellence, in the early 1990s, Rockford's
financial performance deteriorated for a variety of reasons. Inefficient
management and manufacturing resulted in high and volatile costs, excessive
inventory, obsolete materials and finished goods and significant delays in new
product development and delivery. In addition, Rockford had begun to diversify
into home and professional audio products. This diversification initially failed
to enhance Rockford's competitive position, adversely impacted financial
performance and distracted management away from its core business.


     Beginning in 1992, Rockford recruited a new management team, including Gary
Suttle, our President and Chief Executive Officer. Mr. Suttle and his new
management team:

     - hired a number of experienced senior executives and mid-level managers;

     - focused on profitability by establishing and implementing specific
       financial objectives through improved business processes and
       sophisticated management information systems;


     - increased the number of new product introductions from seven in 1991 to
       67 in 1998 while keeping the number of design engineers relatively
       constant;


     - implemented new sourcing and manufacturing strategies, reducing product
       development time-to-market from up to 24 months to approximately six to
       nine months;

     - implemented a more focused advertising and marketing strategy to further
       enhance the Rockford Fosgate and Hafler brand images; and

     - discontinued or redesigned a number of unprofitable and marginally
       profitable product lines.

Primarily as a result of these initiatives, Rockford regained profitability in
the fiscal year ended September 30, 1994. For the fiscal years ended September
30, 1995 and 1996, we experienced decreases in both operating and net income.
These decreases were primarily related to warranty costs resulting from product
quality issues and investments in our infrastructure, including (1) the
reengineering of our speaker facility, (2) our system conversion to Oracle
applications and databases and (3) investments in personnel. In addition, for
the year ended September 30, 1996, sales and marketing expenses increased
significantly primarily due to (1) increased promotional expenses, (2) an
increase in bad debt expenses and (3) higher commissions resulting from
increased sales volume. Beginning in 1997, we began to realize the benefits of
our investments in our infrastructure, resulting in subsequent increases in both
operating and net income. We believe that we have the people, processes and
systems in place to enable us to continue to grow profitably.

     Business

     We generate a substantial portion of our sales from our car audio products.
We recognize revenues from sales when we ship products to the distributor or
dealer. Sales are reported

                                       21
<PAGE>   23

net of discounts and returns. Related expenses, such as commissions, bonuses,
cooperative advertising allowances to dealers and other program expenses,
warranty expenses and bad debt expenses, are accrued when the related sales are
recognized. We have no significant obligations subsequent to shipment, as we do
not install our products, and returns have not been significant to date.


     In the U.S., we sell our car audio products using commissioned independent
sales representative firms who are supported by our employee regional managers.
Internationally, we sell products through a majority owned subsidiary in Japan,
in over 60 other countries through distributors and, since the beginning of
1999, through commissioned independent sales representatives in Canada and
Germany. Unlike in the U.S., we have established relationships with distributors
in certain international markets who purchase our products and resell them to
retailers.



     In 1999, we launched our distribution program with Best Buy. Including its
$4.4 million initial purchase of our products to stock its distribution channel,
Best Buy accounted for 22.7% of our sales for the six months ended June 30,
1999. Our growth plan contemplates that Best Buy will continue to account for a
significant portion of our sales for the foreseeable future.

expenses primarily consist of salaries, sales commissions and costs of
advertising, trade shows, distributor and sales representative conferences and
freight. General and administrative expenses primarily consist of salaries,
facilities and other costs of our accounting, finance, management information
systems, administrative and executive departments, as well as legal, accounting
and other professional fees and expenses associated with the business. Research

(1) Sales are attributed to geographic regions based on the location of
    customers. No single foreign country accounted for greater than 10% of our
    sales.


     In the following discussion, certain increases or decreases may differ due
to rounding.


SIX MONTHS ENDED JUNE 30, 1999 COMPARED TO SIX MONTHS ENDED JUNE 30, 1998



     Sales.  Sales increased by $20.0 million, or 43.5%, to $65.9 million for
the six months ended June 30, 1999 from $45.9 million for the six months ended
June 30, 1998. The increase in sales was primarily attributable to our initial
sales to Best Buy. Including Best Buy's $4.4 million initial purchase of our
products to stock its distribution channel, Best Buy accounted for $15.0
million, or 22.7%, of our sales for the six months ended June 30, 1999. In
addition, sales to car audio specialty dealers increased by $3.6 million, or
9.2%, to $42.8 million for the six months ended June 30, 1999 from $39.2 million
for the six months ended June 30, 1998. This increase is due to improved market
conditions, enhanced incentive programs and the launch of a competitively priced
line of amplifiers and speakers.



     U.S. sales increased by $19.6 million, or 53.7%, to $56.2 million for the
six months ended June 30, 1999 from $36.5 million for the six months ended June
30, 1998. International sales increased by $0.4 million, or 3.8%, to $9.7
million for the six months ended June 30, 1999 from $9.4 million for the six
months ended June 30, 1998. A decrease in sales to certain countries in Latin
America as a result of the region's deteriorating economic conditions was offset
by increased sales in Europe and Canada.



     Cost of Goods Sold.  Cost of goods sold increased by $11.4 million, or
39.7%, to $40.2 million for the six months ended June 30, 1999 from $28.8
million for the six months ended June 30, 1998. Substantially all of the
increase was due to increased sales. As a percent of sales, cost of goods sold
decreased to 61.0% for the six months ended June 30, 1999 from 62.7% for the six
months ended June 30, 1998. The primary reasons for the decrease as a percent of
sales included improvement in global sourcing of raw materials and leveraging of
fixed overhead due to increased production volume.



     Sales and Marketing Expenses.  Sales and marketing expenses increased by
$2.9 million, or 35.5%, to $11.0 million for the six months ended June 30, 1999
from $8.1 million for the six months ended June 30, 1998. The increase was
primarily related to increased sales commissions as a direct result of higher
U.S. sales. U.S. sales are direct to dealers and require commissions to be paid
to our independent sales representatives. International sales have a higher
portion of sales directly to resellers and, while those sales generally have a
lower gross margin, they do not require commission payments. As a percent of
sales, these expenses decreased to 16.7% for the six months ended June 30, 1999
from 17.6% for the six months


                                       23
<PAGE>   25


ended June 30, 1998. The decrease as a percent of sales was primarily because
some expenses in this category are fixed and do not fluctuate with sales.



     General and Administrative Expenses.  General and administrative expenses
increased by $1.6 million, or 31.9%, to $6.7 million for the six months ended
June 30, 1999 from $5.1 million for the six months ended June 30, 1998. The
primary reason for the increase was an increase in our financial
performance-based employee incentive program. As a percent of sales, these
expenses decreased to 10.1% for the six months ended June 30, 1999 from 11.0%
for the six months ended June 30, 1998. The decrease as a percent of sales was
primarily because some expenses in this category are fixed and do not fluctuate
with sales.



     Research and Development Expenses.  Research and development expenses
increased by $0.1 million, or 11.8%, to $1.0 million for the six months ended
June 30, 1999 from $0.9 million for the six months ended June 30, 1998. As a
percent of sales, these expenses decreased to 1.5% for the six months ended June
30, 1999 from 1.9% for the six months ended June 30, 1998.



     Operating Income.  Operating income increased by $4.0 million, or 127.1%,
to $7.1 million for the six months ended June 30, 1999 from $3.1 million for the
six months ended June 30, 1998. This increase was primarily attributable to our
initial sales to Best Buy. As a percent of sales, operating income increased to
10.7% for the six months ending June 30, 1999 from 6.8% for the six months ended
June 30, 1998. The primary reasons for this increase are mentioned above.



     Interest and Other Expense, Net.  Interest and other expense, net primarily
consists of interest expense. These expenses remained level at $0.8 million for
the six months ended June 30, 1999 and 1998. Interest expense was similar for
both periods due to relatively constant levels of debt and interest rates. Upon
completion of this offering, we anticipate repaying all of the amounts due under
our credit facility which would result in recording approximately $260,000 of
expense relating to the deferred loan fees being amortized over the related loan
term.



     Income Tax Expense (Benefit).  Income tax expense increased by $1.4 million
to $2.4 million for the six months ended June 30, 1999 from $1.0 million for the
six months ended June 30, 1998. The effective income tax rates were 38.6% for
the six months ended June 30, 1999 and 42.7% for the six months ended June 30,
1998. The primary reason for the higher effective tax rate for the six months
ended June 30, 1998 was the impact of relatively fixed, non-deductible items for
income tax accounting purposes on a much lower amount of net income. The lower
effective tax rate for the six months ended June 30, 1999 was primarily
attributable to the lower effective tax rate in Michigan, where we experienced
significant increased income from operations without a corresponding increase in
tax expense.


YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997


     Sales.  Sales increased by $0.2 million, or 0.2%, to $87.6 million for 1998
from $87.4 million for 1997. U.S. sales increased by $5.8 million, or 9.0%, to
$70.0 million for 1998 from $64.3 million for 1997 due to market acceptance by
our dealers of our newly redesigned speakers. International sales decreased by
$5.6 million, or 24.2%, to $17.6 million for 1998 from $23.2 million for 1997,
primarily due to economic instability in Latin America and Asia and weakness in
business conditions in Europe.



     Cost of Goods Sold.  Cost of goods sold decreased by $2.2 million, or 3.8%,
to $55.1 million for 1998 from $57.3 million for 1997. Cost of goods sold as a
percent of sales decreased to 63.0% for 1998 from 65.6% for 1997. The primary
reasons for the decrease as a percent of sales included the launch of our raw
material global sourcing strategy, leveraging


                                       24
<PAGE>   26


of fixed overhead due to increased production volume as we prepared for initial
shipments to Best Buy and shifting of sales away from lower margin source units.



     Sales and Marketing Expenses.  Sales and marketing expenses increased by
$0.3 million, or 2.0%, to $14.8 million for 1998 from $14.5 million for 1997.
The increase was primarily related to increased sales commissions as a direct
result of higher U.S. sales. As a percent of sales, these expenses increased to
16.9% for 1998 from 16.6% for 1997.



     General and Administrative Expenses.  General and administrative expenses
increased by $0.9 million, or 9.2%, to $10.2 million for 1998 from $9.4 million
for 1997. This increase was primarily due to the write-off of a $0.4 million
note from our German distributor in 1998 following the distributor's change in
ownership because of the owner's death. The new owner indicated the repayment
would be doubtful based upon deteriorating operating results and a desire to
terminate the relationship. As a percent of sales, these expenses increased to
11.7% for 1998 from 10.7% for 1997.


     Research and Development Expenses.  Research and development expenses
increased by $0.3 million, or 19.0%, to $1.9 million for 1998 from $1.6 million
for 1997. This increase primarily related to increased personnel and product
certification costs. As a percent of sales, these expenses increased to 2.1% for
1998 from 1.8% for 1997.


     Operating Income.  Operating income increased by $0.9 million, or 18.9%, to
$5.5 million for 1998 from $4.6 million for 1997. As a percent of sales,
operating income increased to 6.3% for 1998 from 5.3% for 1997. The primary
reasons for these increases are mentioned above.


     Interest and Other Expense, Net.  Interest and other expense, net decreased
by $0.6 million, or 27.0%, to $1.5 million for 1998 from $2.1 million for 1997.
This decrease primarily related to a decrease in interest expense resulting from
our June 1997 change in lenders, consolidation of various debt instruments and
lower overall effective interest rates, the impact of which was fully realized
in 1998.

     Income Tax Expense (Benefit).  Income tax expense increased by $0.8 million
to $1.7 million for 1998 from $1.0 million for 1997. Our effective income tax
rates were 42.5% in 1998 and 37.0% in 1997. The primary reason for the higher
effective rate in 1998 was higher effective foreign tax rates coupled with a
higher than expected credit for certain foreign sales in 1997 made through our
foreign sales corporation.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996


     Sales.  Sales increased by $4.5 million, or 5.4%, to $87.4 million for 1997
from $82.9 million for 1996. Substantially all of the increase in sales was due
to increased sales in the U.S., where we experienced favorable results from our
dealer incentive programs and the launch of a new speaker and amplifier design.
U.S. sales increased by $4.4 million, or 7.4%, to $64.3 million for 1997 from
$59.8 million for 1996. International sales remained relatively unchanged at
$23.2 million for 1997 and $23.1 million for 1996. However, within the
international regions, sales increased in Asia and Latin America, which were
offset by a decrease in sales to European customers due to less favorable
economic conditions in Europe and the strengthening of the U.S. dollar versus
European currencies.



     Cost of Goods Sold.  Cost of goods sold increased by $0.3 million, or 0.5%,
to $57.3 million for 1997 from $57.1 million for 1996. Substantially all of the
increase was due to increased sales. Cost of goods sold as a percent of sales
decreased to 65.6% for 1997 from 68.8% for 1996. The primary reasons for the
decrease as a percent of sales were the completion of our speaker plant
reengineering resulting in lower manufacturing costs.


                                       25
<PAGE>   27


     Sales and Marketing Expense.  Sales and marketing expenses decreased by
$1.1 million, or 7.0%, to $14.5 million for 1997 from $15.6 million for 1996.
The decrease was primarily related to a planned reduction of marketing
expenditures, specifically advertising and trade shows, to lower our costs. As a
percent of sales, these expenses decreased to 16.6% for 1997 from 18.8% for
1996.



     General and Administrative Expenses.  General and administrative expenses
increased by $1.2 million, or 14.6%, to $9.4 million for 1997 from $8.2 million
for 1996. The primary reason for the increase was costs related to our financial
performance-based employee incentive program, which had no payouts in 1996. As a
percent of sales, these expenses increased to 10.7% for 1997 from 9.8% for 1996.



     Research and Development Expenses.  Research and development expenses
increased by $0.2 million, or 14.9%, to $1.6 million for 1997 from $1.4 million
for 1996. This increase was primarily related to increased personnel and product
certification costs. As a percent of sales, these expenses increased to 1.8% for
1997 from 1.7% for 1996.



     Operating Income.  Operating income increased by $3.9 million, or 540.8%,
to $4.6 million for 1997 from $0.7 million for 1996. As a percent of sales,
operating income increased to 5.3% for 1997 from 0.9% for 1996. The primary
reasons for these increases are mentioned above.


     Interest and Other Expense, Net.  Interest and other expense, net remained
flat at $2.1 million for both 1997 and 1996.

     Income Tax Expense (Benefit).  Income tax expense increased by $1.4 million
for 1997 to $1.0 million from an income tax benefit of $0.4 million in 1996. Our
effective tax rates were 37.0% in 1997 and 30.4% in 1996. The lower effective
tax rate in 1996 was due to the absence of a tax benefit for the portion of the
1996 loss relating to state taxes.

QUARTERLY RESULTS OF OPERATIONS


     Our sales on a quarterly basis reflect the seasonality of the car audio
aftermarket business. Sales are generally greater during the second and third
quarters of each calendar year and lower during the first and fourth quarters,
with our lowest sales typically occurring during the fourth quarter. During the
first quarter of 1999, we launched our distribution program with Best Buy.
Including Best Buy's $4.4 million initial purchase of our products to stock its
distribution channel, Best Buy accounted for 26.5% of our sales in the three
months ended March 31, 1999 and 19.1% in the three months ended June 30, 1999.



     The following tables show selected consolidated quarterly statements of
operations data that were derived from unaudited financial statements for each
of the nine quarters ended June 30, 1999, and also show that data expressed as a
percent of sales for the periods indicated. We believe these unaudited financial
results were prepared on a basis consistent with our audited financial
statements and include all adjustments, consisting only of normal recurring
adjustments, necessary for the fair presentation of our consolidated results of
operations for those periods. The results of operations for any quarter are not
necessarily indicative of the results of any future period.

LIQUIDITY AND CAPITAL RESOURCES


     Since 1995, we have financed our business primarily using cash flows from
operations, borrowings from shareholders and bank borrowings. We had working
capital of $18.2 million at June 30, 1999, compared with $13.5 million at
December 31, 1998. At June 30, 1999, we maintained minimal cash and cash
equivalent balances.



     We currently have a $20.0 million credit facility which is collateralized
by substantially all of our assets, and consists of a revolving line-of-credit,
a term loan and an equipment financing arrangement. At June 30, 1999 the amounts
outstanding under the credit facility consisted of approximately $14.5 million
on the revolving line-of-credit, and approximately $1.2 million on the term
loan. The revolving line-of-credit has a blended variable interest rate per
annum of LIBOR plus 300 basis points and prime plus 75 basis points. The term
loan has a fixed interest rate of 10.67% per annum. The equipment financing
arrangement has, at our option three days prior to the time used, a fixed
interest rate per annum based on five-year U.S. Treasury Notes plus 425 basis
points or a variable interest rate per annum based on the bank's base rate plus
125 basis points. To date, we have not used this equipment financing
arrangement. As at June 30, 1999, the credit facility had a combined interest
rate of 8.31% per annum. The credit facility matures on June 20, 2001. The
credit facility contains restrictions on financial ratios, levels of debt and
capital expenditures.



     We also have a $2.0 million capital lease credit facility under which
leases can be funded up until September 30, 1999 at which time the availability
to enter into additional leases expires. We use the capital lease credit
facility for the purchase of capital equipment under agreements structured as
three-year capital lease obligations. As at June 30, 1999, the capital lease
credit facility had an outstanding balance of $1.1 million with a weighted
average interest rate of 8.0%.



     We also have $995,000 of 8.5% convertible subordinated debentures
outstanding of which $278,953 will be converted into 114,236 shares of common
stock upon completion of the initial public offering. The remainder is due in
May 2002 with interest payable quarterly. We are not permitted to repay the
debentures prior to their due date unless our stock becomes public and trades
for 30 days at a price above $3.66 per share. The debenture holders may convert
the debt to common stock at any time prior to the due date at the rate of $2.44
per share. We also assumed a $450,000 line-of-credit in our acquisition of
Lightning Audio which was repaid after June 30, 1999.



     Net cash provided by (used in) operating activities was negligible for
1998, $6.5 million for 1997 and ($0.2) million for 1996. Net cash provided by
(used in) operating activities was $1.2 million for the six months ended June
30, 1999 and ($0.1) million for the six months ended June 30, 1998. The primary
contributing factor to the growth in our working capital requirements has been
the effect of adding Best Buy as a customer, which has increased our inventory
levels and accounts receivable.



     Net cash used in investing activities was $1.3 million for 1998, $2.1
million for 1997 and $1.8 million for 1996. Net cash used in investing
activities was $2.6 million for the six months ended June 30, 1999 and $0.5
million for the six months ended June 30, 1998. Net cash used in investing
activities was primarily related to purchases of property and equipment, and
during the six months ended June 30, 1999 for our acquisition of Lightning
Audio. We paid for the Lightning Audio acquisition with amounts available under
our line-of-credit.



     Net cash provided by (used in) financing activities was $1.3 million for
1998, ($4.4) million for 1997 and $2.3 million for 1996. Net cash provided by
financing activities was $2.3 million for the six months ended June 30, 1999 and
$1.2 million for the six months ended June 30, 1998. Net cash provided by (used
in) financing activities was primarily related to borrowings and repayments of
our credit facilities and other debt obligations, including


                                       28
<PAGE>   30

repayments of various senior notes and other debt obligations during 1997, at
the time our $20.0 million credit facility was established.

     We may pursue acquisitions of businesses, products or technologies that
could complement or expand our business and product offerings. Any material
acquisition could result in an increase in our working capital requirements
depending on the amount, timing and nature of the consideration to be paid.


     We believe that the net proceeds to be received by us from this offering,
together with potential cash flows from operations, will be sufficient to meet
our anticipated cash needs for working capital, capital expenditures and other
activities for at least the next twelve months. Thereafter, if current sources
are not sufficient to meet our needs, we may seek additional equity or debt
financing. In addition, any material acquisition of complementary businesses,
products or technologies could require us to obtain additional equity or debt
financing. There can be no assurance that additional financing would be
available on acceptable terms, if at all.


IMPACT OF THE YEAR 2000

     Readiness.  We use and rely on a variety of information technologies,
computer systems and scientific and manufacturing equipment containing
computer-related components, such as programmable logic controllers and other
embedded systems. We have a Year 2000 project to address the impact of Year 2000
issues on our computer systems and scientific and manufacturing equipment and
the readiness of our critical third parties. Our Year 2000 project is designed
to:

     - take inventory of and prioritize business critical systems;

     - analyze each system's Year 2000 compliance;

     - undertake remedial activities, including repairing or replacing
       identified systems;

     - test the effectiveness of any remedial activities;

     - identify and analyze compliance of critical third parties that provide
       goods and services to us; and

     - develop contingency plans, if internal or external systems fail.

We believe that approximately 90% of our Year 2000 compliance work is complete
with the remaining work scheduled for completion by the end of the third quarter
of 1999.


     Information and Operation Systems.  In 1994, we invested in a new
Enterprise Resource Planning (ERP) system that was Year 2000 compliant. Since
1994, we have monitored our internal environment to evaluate whether all
products added to our system are also Year 2000 compliant. In 1997, we performed
a physical inventory of all process equipment containing embedded chips,
software products, operating systems, telecommunications products and hardware
products. We then assigned Year 2000 compliance responsibility for each category
to a specific internal group. The process-engineering group addressed the
process equipment category which contains embedded chips by contacting each
supplier and confirming that the equipment supplied was Year 2000 compliant.



     In June 1997, our information system department upgraded our business
applications to 10.7 of Oracle's ERP Application Suite, which Oracle has
certified as Year 2000 complaint. The business application suite is our
informational backbone.



     In May 1999, we upgraded to release 11 of the Oracle ERP Application Suite
and successfully performed a Year 2000 audit on the new release. Additionally,
we sponsored an


                                       29
<PAGE>   31


external audit of the Oracle ERP Application Suite which did not reveal any Year
2000 problems.



     We use Novell Network Management Products 4.11 and 5.0 to manage our
telecommunications, and Novell has certified both products as Year 2000
compliant. Additionally, we run the software programs "Check 2000" and "Zen Y2K"
to monitor our desktop computers and test Year 2000 compliance in our network.
To date, we are 95% complete with our inventory, compliance analysis and testing
of business critical financial, information and operational systems, including
manufacturing control systems.



     Third Party Year 2000 Compliance.  We have taken the following steps to
assess the Year 2000 readiness of our third parties. For our suppliers, we sent
a general inquiry letter in March 1998 to which all of our critical suppliers
responded that they were or would be Year 2000 compliant before the Year 2000.
In June 1999, we sent a follow-up detailed questionnaire to our 51 critical
inventory suppliers requesting information of their Year 2000 assessment,
planning, testing, supply chain and contingency plans. We are beginning to
receive and analyze the responses to these surveys. For our equipment
manufacturers, we sent written inquiries requesting confirmation of Year 2000
compliance and received positive responses from each major manufacturer. For
communications, utilities, shipping vendors, financial institutions and
professional services, we have either contacted directly or reviewed Web sites
to confirm Year 2000 compliance of 90% of these entities. To date, we have not
discovered any third party Year 2000 compliance issues and have targeted August
31, 1999 for our completion of this process.



     Costs.  To date, we have not incurred any material costs in identifying or
evaluating Year 2000 compliance issues. The total costs of the Year 2000 systems
assessments and conversions are currently funded through cash flows from
operating activities and we are expensing these costs as they are incurred. Most
of our expenses have related to, and are expected to continue to relate to, the
operating costs associated with time spent by employees in the evaluation
process and Year 2000 compliance matters in general. Most of these costs have
already been incurred and we do not anticipate significant future costs with
respect to the remaining efforts. To date, we have not deferred any information
technology initiatives as a result of our Year 2000 project.



     Risks.  We believe that the chance that our computer systems and
manufacturing equipment are not Year 2000 compliant is minimal. Third-party
goods or services incorporated into our products may need to be revised or
replaced, which could be time consuming and expensive. Our inability to fix any
Year 2000 compliance problems on a timely basis could result in lost sales,
increased operating costs and other business interruptions, any of which could
have a material adverse effect on our business, financial condition and results
of operations. In addition, governmental agencies, utility companies,
third-party service providers and others outside our control may not be Year
2000 compliant and their failures could result in an internal failure beyond our
control, which could have a material adverse effect on our business, financial
condition and results of operations. We believe the most likely worst-case
scenario would involve a complete failure by our electricity providers, since
all of our operations would be disrupted in that event.



     Contingency Plan.  We are engaged in an ongoing Year 2000 assessment and
intend to implement, no later than August 31, 1999, a contingency plan to
address:



     - inventory requirements;



     - secondary sources for critical inventory supplies, communications and
       manufacturing equipment; and



     - a back-up computer system.



We will take into account the results of our Year 2000 simulation testing and
the results of our third-party surveys in determining the nature and extent of
our contingency plans.

                                    BUSINESS

OUR BUSINESS


     We design, manufacture and distribute high-performance car audio and
professional audio systems. Our car audio products include technologically
advanced amplifiers, speakers, source units and accessories marketed under our
Rockford Fosgate brand name. We sell these products in the car audio aftermarket
to consumers who are upgrading their car audio systems. We market our
professional audio amplifiers and speakers under our Hafler brand name.



     Rockford Fosgate is one of the world's premier high-performance car audio
brands and for nearly 20 years, it has been the brand of choice among our core
consumers, particularly 16-24 year old males. We believe our brand appeals to
our Generation Y core consumers because they view Rockford Fosgate as the
"coolest" car audio brand. Many of our core consumers are extremely, almost
fanatically, loyal to our Rockford Fosgate brand, and proudly display our logos
on their cars, clothing and even their bodies.



     Our marketing and product development efforts are designed to enhance our
brand image and generate increased loyalty among our core consumers and the
retailers who sell our products. We believe our core Generation Y consumers, who
devote much of their time and disposable income to their car audio systems,
desire distinctive "leading edge" products and powerful, high quality sound.



     In addition, we believe our hard-hitting, "in your face" advertising
combined with cutting-edge technology and product innovation allows the
retailers who sell our products to appeal to Generation Y and other consumers
who are attracted by our brand, products and distinctive marketing programs. To
maintain and further enhance our unique heritage, we continue to develop new
products that are reliable, durable, technologically advanced and designed to
set industry standards in their product categories. Our Rockford Fosgate and
Hafler products have won numerous consumer and industry awards. We are committed
to maintaining our premier position in car and professional audio by working
closely with distributors, retailers and consumers to satisfy their needs and
preferences.

OUR INDUSTRY

     Car Audio


     We believe that total worldwide factory sales of car audio products were
approximately $14.7 billion in 1998, of which $6.3 billion represented
aftermarket sales. We also believe total factory sales of car audio products in
the U.S. were approximately $4.4 billion in 1998, of which approximately $1.9
billion represented aftermarket sales. The international car audio market is
significantly larger, with estimated factory sales of car audio products of
approximately $10.3 billion in 1998, of which $4.4 billion represented
aftermarket sales.


     The U.S. car audio aftermarket industry is mature and highly fragmented
with many companies competing for market share. Competition comes predominantly
from specialty audio suppliers that generally compete in specific market niches
on the basis of brand image, quality and technology, and large consumer
electronics suppliers that offer car audio products as part of their broad
consumer electronics lines. The larger specialty audio suppliers and consumer
electronics suppliers have been increasing their market share at the expense of
the smaller specialty audio suppliers, who often lack the capital and other
resources necessary to satisfy the demands of retailers. As a result, industry
consolidation is accelerating, with more efficient vendors capturing incremental
market share and further leveraging costs.

     Car audio aftermarket products are typically distributed to consumers
through the following channels:

     - Specialty dealers:  Retail stores specializing in car audio products;

     - Audio/video retailers:  Retail stores specializing in car audio, home
       audio and video products;

     - Consumer electronics retailers:  National consumer electronics chains,
       such as Best Buy and Circuit City;

     - Catalog merchants:  Mail order retailers, such as Crutchfield;

     - Mass merchants:  National mass merchandisers, such as K-Mart, Target and
       Wal-Mart; and

     - Automotive retailers:  Auto parts retailers, such as AutoZone and Pep
       Boys.


Historically, specialty dealers have dominated the retail distribution of car
audio aftermarket products. Over the last several years, as a result of changing
consumer buying patterns, the audio/video and consumer electronics retailers
have been the fastest growing distribution channels for car audio products
increasing their combined market share from 34.5% in 1987 to 50% in 1997.


     Professional Audio

     The professional audio market is focused on consumers who use audio
equipment in commercial applications. Professional audio products are used in
recording studios, movie theaters, concert facilities, stadiums, traveling bands
and broadcast studios. The professional audio market requires technical
information to assist buyers in the sales process and has become increasingly
price competitive. To reduce costs, many manufacturers have shifted to overseas
component suppliers.

OUR CONSUMERS

     Car Audio

     Historically, 16-24 year old males have been the primary consumers of
high-end car audio aftermarket products. Generation Y consumers possess
substantial disposable income and devote much of their time and money to their
music and cars. They are part of Generation Y, the 10-24 year old age group that
is one of the fastest growing segments of the U.S. population. According to U.S.
Census Bureau, Generation Y is estimated to grow from 57.0 million in 1998 to
61.6 million in 2005. This growth rate would outpace the estimated general
population growth by 56.7%.

     Today's 16-24 year old male consumers have an increasing preference for
brand names, durability and high-performance products and are more knowledgeable
about car audio products than prior generations. Consumer electronics retailers
devote significant square footage to car audio products because they have found
the category to be a very important traffic driver, particularly of Generation Y
consumers.


     Our newly acquired Lightning Audio brand is positioned to offer our
consumers an alternative that is cool to own but more moderately priced than our
premium Rockford Fosgate brand. We believe this will enable us to sell to an
even larger number of consumers.


     Professional Audio

     Our professional audio consumers are typically more technically oriented
and drawn from a broader range of age groups. These consumers use our products
primarily for commercial applications and in their professional activities.

OUR GROWTH STRATEGY

     Our goal is to design, produce and distribute the best engineered and most
recognized and respected brands of high-performance car and professional audio
products in the world. Each element of our strategy is intended to enhance and
reinforce the global brand images of Rockford Fosgate and Hafler among consumers
and retailers. Key elements of our growth strategy are to:


     Expand Channels of Distribution.  We believe our selective distribution
increases brand loyalty, enhances retailers' profit margins and encourages
retailers to carry a broad range of our products. We have recently increased our
channels of distribution, focusing on some of the fastest growing and most
efficient retailers in the U.S. and selected international markets. For example,
in early 1999, we began distributing our car audio products through Best Buy, a
leading consumer electronics and car audio retailer, with more than 300 stores
in the U.S. Best Buy concentrates its in-store merchandising on a few high
quality suppliers in each of its product categories and has devoted selling
space and financial and operating resources to promote and sell our products. In
addition, in August 1998, we began selling our products to Crutchfield, a car
and home audio catalog retailer in the U.S., as well as continuing to sell
through the Autobacs and Yellow Hat consumer electronics chains in Japan.



     Develop a Second Brand.  In response to requests from our retailers and
international distributors, we intend to develop a second brand to be sold at
more moderate price points than our current products. Consistent with our
Rockford Fosgate and Hafler brand images, however, we expect that these products
will continue to offer the highest performance and quality standards in their
categories. In June 1999, we acquired Lightning Audio, a manufacturer and
distributor of car audio accessories. We intend to introduce a line of
moderately priced, high-performing amplifiers and subwoofers under the Lightning
Audio brand name in 2000. We believe the addition of a second brand will help us
enhance and expand our product offerings and increase our distribution
capabilities.


                                       33
<PAGE>   35


     Capitalize on International Opportunities.  We believe that the Rockford
Fosgate brand name is as widely recognized in many foreign countries as it is in
the U.S. We intend to aggressively expand Rockford Fosgate, Lightning Audio and
Hafler in international markets. We currently sell our car audio products
directly to retailers in Canada, Germany and Japan, and through independent
distributors, to over 60 other countries. Unlike in the U.S., we have
established relationships with distributors in certain international markets who
purchase our products and resell them to retailers. Recently, we initiated a
strategy of moving to a "one-step" distribution system in larger international
markets by converting selected distributors into independent sales
representatives, allowing us to sell directly to retailers. We expect these
measures to substantially increase our sales in these markets by allowing us to
better compete through lower distribution costs and reduced prices to the
consumer.



     Introduce New and Innovative Products.  We intend to take advantage of the
strength of the Rockford Fosgate and Hafler brands by continuing to introduce
new and innovative products. We believe our ability to quickly deliver
innovative products to market appeals to consumers' desire for "leading edge"
products and provides a significant competitive advantage. In recent years, this
strategy has been effective both in launching our new products and increasing
sales of our core products. For example, we recently introduced new source units
and mid-range speakers for the Rockford Fosgate brand, and are developing home
theater products under the Hafler brand.



     Promote Our Unique Brand Image.  We believe our core consumer, the
Generation Y 16-24 year old male, perceives our brand as the "coolest" in the
car audio product category. We intend to continue to enhance the Rockford
Fosgate, Lightning Audio and Hafler brands by projecting an image that appeals
to consumers who appreciate brand authenticity and value. We believe that the
combination of our hard-hitting advertising campaigns with our rugged and
durable products has created worldwide recognition and loyalty among our core
consumers. Many of our consumers proudly display our logos on their cars,
clothing and even on their bodies. In addition, we believe demand for our brand
and products provides retailers with a powerful tool to expand their customer
base by generating increased foot traffic of Generation Y and other consumers.

     Car Audio


     We offer a full line of high-performance car audio products. The following
table provides examples of specific products within each of our product lines:

                          clothing
</TABLE>



     Amplifiers.  Amplifiers increase the voltage and current coming from the
source unit, providing more power than possible from a source unit alone.
Amplifiers are essential for a high-performance car audio system and are
typically not part of a standard factory installed system. We sell 21 different
models of amplifiers under our Punch brand, with rated power from 100 to 1,100
watts and with minimum advertised prices ranging from $179.95 to $1,329.95. Our
amplifiers provide 1, 2, 4 and 5 channel alternatives, giving consumers the
ability to select an optimum configuration for their system. For specialized
applications, we also sell stand-alone signal processors that accept input from
a source unit, modify the signal to provide the consumer with enhanced
performance and deliver the signal to one or more amplifiers.


     Speakers.  Speakers accept a signal from a source unit or amplifier and
translate it into sound. There are two categories of speakers: those eight
inches or greater in diameter are considered subwoofers and are designed to play
lower (bass) frequencies; and those less than eight inches in diameter are
considered speakers and are designed for higher frequencies. Aftermarket
speakers and subwoofers provide dramatically improved sound quality compared to
most factory installed car audio systems and are often the single most important
improvement consumers can make to their car audio sound system. We sell 88
different models of car audio speakers under our Punch brand with minimum
advertised prices ranging from $59.95 to $549.95.

     Source Units.  Source units are the control center for a car audio system.
Typically mounted in the dash of the car, source units provide input signals,
including AM/FM radio and compact disc players. Most of our units have the
ability to control a CD changer. We sell three different models of source units
under the Rockford Fosgate brand with minimum advertised prices ranging from
$249.95 to $349.95. Additionally, we sell 8-disc CD changers with a minimum
advertised price of $299.95.


     Accessories.  We sell over 400 different types of accessories under the
Connecting Punch brand, including amplifier installation kits, RCA cables and
carpet/fabric/surface applications. We also sell over 1,000 different types of
accessories under the Lightning Audio brand, including stiffening capacitors,
battery clamps, RCA and speaker cables. We also sell promotional materials and
clothing under the Punch Sport brand.



     Our Rockford Fosgate products have won numerous consumer and industry
awards, including Autosound Grand Prix awards in every year from 1987 through
1999, Innovations awards at the Consumer Electronics Shows in 1997, 1998 and
1999 and European Car Audio Press awards in 1997 and 1998.

     Professional Audio


     We sell professional audio amplifiers and speakers under the Hafler brand
name. Suggested retail prices range from $569.00 to $2,200.00. Our professional
audio products are used in recording studios, movie theaters, concert
facilities, stadiums, traveling bands and broadcast studios. Due to
manufacturing and technical similarities with the Rockford Fosgate brand, many
processes and technologies are shared and developed across both brands. Our
Hafler products won awards from Pro Audio Review in 1996 and 1997, Mix Magazine
in 1996 and 1998 and Canadian Music-Music Week Magazine in 1999, as well as
receiving the EQ Award in 1997 and Electronic Musician Editor's Choice Award in
1999.


RESEARCH AND DEVELOPMENT


     Research and development is a primary focus of our business because of the
heavy demand by our core consumers for leading-edge products. We focus our
research and development efforts primarily on enhancing current products and
developing new products. Our engineering processes involve a coordinated effort
across multiple areas of our company. As at June 30, 1999, our research and
development staff consisted of eleven design engineers, as well as other support
staff, dedicated to project development and who coordinate their efforts with:



     - our sales group to identify features consistent with market requirements
       and our brand image;



     - our manufacturing staff to develop and build products more efficiently;



     - our product support staff to identify weaknesses in our existing products
       and to help re-design them; and



     - our customers -- both at the retailer and consumer level -- to help us
       better understand their needs and preferences and incorporate them into
       our products.



     As a result of these efforts, we have reduced product development
time-to-market from up to 24 months to an average of six to nine months, as
compared to over twelve months for many of our competitors. Our objective is to
introduce new products or re-engineer approximately one-third of our existing
product line annually. In 1998, more than 60% of our sales were generated from
new or re-engineered products.



     Part of our research and development efforts seek to create a reserve base
of technologies and innovations that are available to our engineers for use in
the product development process. As a result, we can readily respond to changing
demand and effectively execute our marketing plans by introducing new products
and by adding features to our existing products. Examples of product innovations
that have been or are being developed from this reserve technology base include:



     - powered speakers, which are speakers that include an integrated
       amplifier;



     - remote bass and speaker controls;



     - active cross-overs that allow consumers to tailor our amplifiers to their
       systems' needs;



     - class BD amplifiers that incorporate a more efficient circuit design;



     - more reliable mechanical components;



     - materials improvements that increase the durability and performance of
       our products; and



     - digital signal processing.

SALES, MARKETING AND DISTRIBUTION


     Our sales and marketing efforts are designed to enhance our brands by
projecting an image that appeals to consumers who appreciate brand authenticity
and value. We believe that the combination of our hard-hitting advertising
campaigns with our rugged and durable product offerings has created worldwide
recognition and loyalty among our core consumers. We promote our products with
monthly, bi-monthly and quarterly full page advertisements in fourteen car audio
magazines and publications. We participate in six annual trade and consumer
shows and contests, and supply promotional prices and giveaways. We publish a
complete set of full color brochures and promotional literature detailing each
of our products. Our products also appear in advertisements on television,
newspapers and the Internet. We also help promote concerts and compact discs
that were produced using Hafler products.



     Our sales and marketing activities are listed below in their order of
importance:


     - making regular calls to dealers and providing them with demonstration
       products, point-of-purchase displays and other marketing materials;

     - initiating targeted advertising in periodicals read by our potential
       consumers;

     - training dealer installation personnel at our Rockford Technical Training
       Institute;

     - participating in rule making for, and providing technical and product
       support to, auto sound competitions; and

     - participating in related professional and consumer trade shows.


     We consider our advertising to be both hard-hitting and "in your face"
because our advertisements are intense, frequent and intended to excite our core
consumer. We use the explosive imagery of the wolf in our visual advertisements
and booming sound bites in our audio campaign to promote the power, quality and
intensity of our products.


     Our corporate Web site, located at www.rockfordcorp.com, offers consumers
and retailers reliable and comprehensive information about our product offerings
and consumer services. Because our core consumers are among the most
enthusiastic users of the Internet, we believe expanded Internet-based marketing
will broaden our consumer reach, enhance our brand image and direct potential
consumers to our retailers. Our Web site offers retailers, sales representatives
and distributors an efficient method to track order status, accounts receivable
and sales history and to access marketing and advertising materials. Consumers
can currently purchase Punch Sport promotional materials and clothing from our
corporate Web site. In addition, we intend to sell our upcoming Hafler home
theater products over the Internet.


     Lightning Audio has a separate Web site at www.lightningaudio.com, which
features comprehensive information about Lightning products, dealers and
promotions.


     Car Audio Distribution


     We currently sell our Rockford Fosgate car audio products in the U.S.
through a network of over 1,500 retail stores and 18 independent sales
representative firms who identify, recruit and sell to dealers in their regions.
Our representative firms, serviced by our three in-house regional managers,
employ a total of approximately 60 field personnel who make regular calls on
dealers in their region. We have entered into one-year agreements with each of
these firms under which we appoint them our sales representative for a specific
territory and specific products under varying terms.


                                       37
<PAGE>   39


     Our U.S. distribution system is composed of independent specialty dealers,
audio/video retailers, consumer electronics chains and catalog merchants. Our
dealers and distributors sign agreements under which we appoint them to serve a
specific territory to distribute our products under varying terms. In early
1999, we launched our distribution program with Best Buy, one of the larger
consumer electronics retailers. Best Buy sells our products in all of its more
than 300 stores nationwide. Our expansion into Best Buy represents an evolution
in our strategy to distribute through additional channels. We believe our
expansion into Best Buy will:


     - further increase recognition of the Rockford Fosgate brand;

     - distribute our products to a more diverse set of consumers, including
       females and older males;

     - expand market share among our core consumers since many of them shop at
       Best Buy stores;

     - expand our sales into geographic markets where we currently have little
       presence; and


     - allow our specialty dealers to grow their sales by taking advantage of
       increased product visibility created by Best Buy's advertising programs.


     We currently sell our car audio products in over 60 other countries through
independent distributors and sales representatives. Selling through distributors
has allowed us to expand into international markets while minimizing cultural
differences and local marketing issues, such as warranty service. In Japan, we
sell to independent distributors through our majority owned subsidiary.


     During 1999, we initiated a program to convert selected foreign markets to
a "one-step" distribution system by switching to independent sales
representatives. This system allows us to sell directly to retailers rather than
to distributors who further mark-up our products before selling them. We expect
this transition to substantially increase our penetration in these markets by
reducing prices to the consumer while providing us with a higher gross margin.
Because relatively high sales volumes are needed to justify the use of
independent sales representatives, we anticipate converting some higher volume
territories over time while continuing to distribute through distributors in
smaller territories. To date, we have successfully completed the conversion to
the one-step distribution system in Canada and Germany.



     We sell Lightning Audio products in the United States through a network of
15 independent distributors and over 400 independent retailers. We also sell
Lightning Audio products internationally through 123 independent distributors
who sell our products in 30 countries.


     Professional Audio Distribution

     In the U.S., sales of professional audio products primarily are made
through sales representatives to small specialty dealers and larger retail
chains, such as Guitar Center and Sam Ash. Internationally, sales are primarily
made through approximately 28 independent distributors in over 30 countries. We
also plan to sell Hafler home theater products directly over the Internet in the
future.


PRODUCT SUPPORT


     To maintain and enhance our relationships with retailers, we provide
numerous support services, including product and installation training, sales
training, technical and customer service support and advanced information
systems, including an interactive Web site. Our
                                       38
<PAGE>   40

Web site provides comprehensive and valuable information for dealers and
distributors, including product schematics, ad layouts and logos. Our Rockford
Technical Training Institute, one of the first and most advanced of its kind in
our industry, trains over 700 retailer sales and installation personnel per year
on our special methods and unique culture. In addition, our instructors and
demonstration vehicles travel worldwide hosting dealer instruction seminars.

     Our products carry standard warranties against defects in material and
workmanship, and we will either repair or replace any product that fails to meet
this warranty. Repair services are available for products which are no longer
covered under the original warranty. For our U.S. customers, we have in-house
customer service, repair and technical support personnel who provide general
company information, installation support, troubleshooting, and system design
assistance. We provide a unique rapid factory direct repair program that repairs
and ships products within 24 hours of receipt, reducing retailer and consumer
inconvenience if our products fail to perform properly. For our international
customers, our distributors provide customer service and warranty support.

MANUFACTURING

     We believe our efficient production, sourcing and distribution capabilities
make us one of the preferred suppliers in the car audio aftermarket.


     We manufacture amplifiers, signal processors and various accessories at our
facilities in Tempe, Arizona and mid-range speakers, woofers and subwoofers at
our facility in Grand Rapids, Michigan. In 1999, Hyundai Electronics signed a
four-year joint development agreement with us to supply all of the source units
we resell under the Rockford Fosgate brand name in accordance with our
specifications. Other third parties manufacture our full-range speakers and
various components according to our design specifications. We use cellular
manufacturing processes and just-in-time supply management in all our
manufacturing facilities. Cellular manufacturing provides flexibility and
efficiency because any cell can manufacture any product, depending on market
demand. Lot sizes are small and feedback from the manufacturing process is
quick. We use advanced surface mount technology in our electronics
manufacturing. Surface mount technology is accurate, increases the density of
circuits and reduces labor content. Our flexible manufacturing and in-house
engineering capabilities are a key part of our efforts to shorten lead times
from concept to production, respond rapidly to changing demand and reduce our
parts and raw materials inventory. Both of our facilities focus on continuous
improvement, with quality control embedded in the manufacturing process. The
result has been improved flexibility, increased efficiency and greatly improved
cycle times.



     We recently shifted from purchasing parts and materials solely in the U.S.
to purchasing from the best suppliers available to us worldwide. This global
sourcing initiative was a critical shift in our raw materials strategy, allowing
us to deliver high quality, low-cost goods that are competitive with those
offered by our U.S. and international competitors. Global sourcing of our
component parts provides us the best total cost suppliers and introduces us to
worldwide technologies and materials.


COMPETITION

     Our markets are very competitive, highly fragmented, rapidly changing and
characterized by price competition and, in the car audio market, rapid product
obsolescence. Rockford competes in the car audio market on the basis of brand
recognition, innovation and

                                       39
<PAGE>   41

technology, quality and reliability, breadth of product line, distribution
capabilities and price. Competition comes predominantly from two categories:

     - Specialty audio suppliers.  These companies generally compete in specific
       market niches on the basis of brand image, quality and technology.
       However, many of these companies are undercapitalized, lack the buying
       power necessary to develop cost efficiencies and lack the infrastructure
       to efficiently source raw materials, manufacture components and systems,
       and distribute finished products.

     - Large consumer electronics companies.  These companies offer car audio
       products as part of their broad consumer electronics lines. They have
       efficient operations but are volume-driven and generally do not respond
       as quickly to changing consumer preferences as do smaller specialty
       suppliers. Consumer perception of the quality of their products is often
       not as high, frequently resulting in lower brand image and profit
       margins. These companies tend to focus on the larger market segments,
       such as source units, and generally do not focus on the smaller market
       segments, such as amplifiers and subwoofers.

     Some of our competitors have greater financial, technical and other
resources than we do and many seek to offer lower prices on competing products.
To remain competitive, we believe we must regularly introduce new products, add
performance features to existing products and limit increases in prices or even
reduce them. Our principal competitors within our product lines are listed
below:

     - Car Audio Amplifiers:  Alpine, Kenwood, Kicker, MTX, Orion, Phoenix Gold
       and PPI;

     - Car Audio Speakers:  Blaupunkt, Boston Acoustics, Infinity, JBL, JL
       Audio, Kenwood, Kicker, Pioneer and Polk;

     - Car Audio Source Units:  Alpine, Blaupunkt, Clarion, Fujitsu Eclipse,
       Kenwood, Nakamichi, Pioneer and Sony;


     - Car Audio Accessories:  Monster Cable, Phoenix Gold and Stinger; and


     - Professional Audio Amplifiers and Speakers:  Cress, Crown, Eastern
       Acoustic Works, Mackie Designs, Peavy, QSC and Tannoy.


     We believe we rank first among our competitors in car audio amplifiers and
are in the top five among our competitors in car audio speakers and accessories.
We believe we are a relatively minor competitor in car audio source units and
are new to the professional audio speaker market. We believe we rank first in
the recording studio segment of professional audio amplifiers and that we are a
small player in the remaining part of the professional audio market.


     We also compete indirectly with automobile manufacturers, who may improve
the quality of original equipment sound systems, reducing demand for aftermarket
car audio products. They may also change the designs of their cars to make
installation of our products more difficult or expensive.

INFORMATION SYSTEMS


     We have a fully integrated system based on a Novell network, Oracle
applications and databases, Microsoft Office applications and a Cisco
infrastructure. We also created a three tier open architecture with
plug-and-play and open interface tables.


                                       40
<PAGE>   42

     Our information systems are designed to respond quickly to inquiries from
our managers, employees, suppliers and customers. They are designed to support
our efforts to:

     - produce high quality products;

     - reduce working capital requirements;

     - decrease the time to market for new products;

     - deliver orders faster; and


     - provide accurate and timely information.



     Our information systems assist us in producing high quality products
quickly and affordably by providing immediate quality information about our
business. Our advanced messaging systems collect feedback about product quality
from our customer service department that we send directly to our engineering
and manufacturing groups. This early customer feedback permits prompt
adjustments and serves as an immediate indicator of our products' market
acceptance. Our common drive is accessible to authorized employees for new
product information and timely updates. Management has access to secured
databases regarding the status, cost and projections for pending projects,
enabling quick adjustments to scheduling and use of resources.



     We have implemented Web-based systems to provide accurate and timely
information and allow our representatives, dealers and distributors to check the
status of their orders at our secure Internet site. We also have designed and
tested systems to accept orders from consumers over the Internet in preparation
for distribution of our Hafler home theater products.


INTELLECTUAL PROPERTY


     We rely upon a combination of trade secret and trademark laws,
non-disclosure agreements and patents to protect our proprietary rights. We have
registered many trademarks and trade names both in the U.S. and internationally
and are committed to maintaining and protecting them. We believe our trademarks
and trade names are material to our business and are well known among consumers
in our principal markets. Our principal trademarks and trade names include:


     - Rockford Fosgate(R);

     - The Punch(R);

     - Connecting Punch(R);

     - Punch Sport(R);

     - Practice Safe Sound(R);

     - Car Audio for Fanatics(R);


     - Lightning Audio(R);



     - Storm(TM);



     - Bolt(TM);



     - Strike(TM);


     - Hafler(R); and

     - Our "Diamond R" logo.

(1) We have the right to extend these leases for two additional one-year terms.


ENVIRONMENTAL COMPLIANCE


     Whenever possible, we avoid using hazardous materials in our production
processes. Two chemicals used in our basic processes, lacquer and flux, are
listed as hazardous materials by the U.S. Environmental Protection Agency. We
use them in limited quantities in our production facility, taking care to see
that they are stored, used and disposed of in the proper manner. We believe that
compliance with federal, state, local and foreign provisions regulating the
discharge of materials into the environment, or otherwise relating to the
protection of the environment, will not have a material effect upon our capital
expenditures, earnings and competitive position. We do not anticipate material
capital expenditures for environmental control facilities for the remainder of
the current fiscal year, or the succeeding fiscal year.


LEGAL PROCEEDINGS


     In 1998, Integrated Electronic Technologies (IET) alleged in correspondence
that our patented TOPAZ circuit design infringed a patent of IET. The TOPAZ
circuit is used in our higher-priced "Punch" line of car audio amplifiers and in
our Hafler professional amplifiers. We believe that IET's allegations are
without merit. IET has not initiated any legal proceedings relating to this
claim and has not communicated with us about it since September 1998.



     In addition to the above, we are and may continue to be a party to various
lawsuits and arbitrations from time to time. As of June 30, 1999 we were not a
party to any legal proceedings that we believe are material.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

compensation committee of any entity which has one or more executive officers
serving as a member of our board of directors or nominating and compensation
committee.

1998 STOCK OPTION GRANTS

     The following table summarizes the stock options we granted to our officers
listed on the Summary Compensation Table for 1998. We have never granted any
stock appreciation rights.

     The Securities and Exchange Commission requires that we use the assumed
annual compounded rates of stock price appreciation of 5% and 10% shown in this
table. These rates are only an illustration and are not based on our anticipated
results. Our stock price may increase or decrease, based on market conditions,
our performance and many other factors. You should not rely on the amounts in
this table as a projection of our performance over any time period.

(1) All options were granted under our 1997 Stock Option Plan. 25% of the option

(2) This column represents the hypothetical gain if (1) the employee exercises
    the options at the end of the option term, (2) the shares had a fair market
    value on the date of grant equal to the option price and (3) the shares
    appreciate at the assumed rates of compounded annual growth. The employee's
    actual gain, if any, will depend on the performance of our stock and on
    market conditions. It may be more or less than the assumed amounts.

1998 OPTION EXERCISES AND YEAR-END OPTION VALUES


     The following table contains information concerning the exercise of stock
options during the fiscal year ended December 31, 1998 by our officers listed on
the Summary Compensation Table:


     - the shares that our executive officers purchased during 1998 by
       exercising their stock options; and


     - the number and value of unexercised options our officers listed on the
       Summary Compensation Table held at December 31, 1998. Value is determined
       by subtracting the exercise price from our board's deemed fair market
       value at that date.

STOCK OPTION PLANS

     We have two stock option plans, the 1994 Stock Option Plan and the 1997
Stock Option Plan. The plans are substantially similar. Both provide for the
grant of incentive stock options and non-qualified stock options to our
consultants, directors, officers and key employees. The purpose of the plans are
to:

     - attract and retain skilled and qualified officers, directors and key
       employees;

                                       47
<PAGE>   49

     - motivate them to achieve our long-range goals; and

     - align their interests with the interests of our shareholders.

     The board of directors adopted the 1994 Stock Option Plan on January 26,
1995 and the 1997 Stock Option Plan on April 22, 1998. The shareholders approved
the 1994 plan on April 25, 1995 and the 1997 plan on April 22, 1998.


     We have reserved a total of 2,150,000 shares for issuance under both plans.
As at June 30, 1999, we had:



     - issued 32,034 shares under the plans;



     - outstanding options to purchase 1,780,981 shares under the plans at a
       weighted average exercise price of $3.55 per share; and



     - 336,984 shares still available for future grant.



Shares of common stock reserved for issuance upon the exercise of options under
a plan are available for future reissuance under the plan if the options expire
or terminate without being exercised. Under the 1997 plan, the maximum number of
shares any individual may receive during a calendar year is 430,000 shares.
There is no similar maximum under the 1994 plan. Under both plans, in the case
of incentive stock options, the aggregate fair market value of stock that is
exercisable for the first time by any individual during any calendar year may
not exceed $100,000.


     The nominating and compensation committee of the board of directors
administers the plans. The committee has discretion to determine:

     - who should receive options;

     - how many shares to include in each grant;

     - the exercise price for each option;

     - whether an option should be an incentive option or a non-statutory option
       under the federal tax laws (except that only our employees may receive
       incentive options);

     - the vesting schedule for each option;

     - the term of each option; and

     - other material terms of the options granted.

Option holders may pay the exercise price for options in cash or, at the
committee's discretion, in shares of common stock. Also at the committee's
discretion, option holders may exercise on a cashless basis through the same-day
sale of the purchased shares.

     The vesting schedule for all options awarded to date provides for 25% of
the option shares granted to vest on the date of grant and 25% to vest on each
of the first three anniversaries of the grant date. The options also fully vest
if we agree to sell all or substantially all of our assets or shares or to merge
with another company if our shareholders do not have a controlling interest in
the surviving entity.

     Prior to expiration of the 1994 plan on December 22, 2004 and the 1997 plan
on October 28, 2007, the board of directors may terminate, amend or modify
either plan at any time; however, no termination, amendment or modification may
adversely change the rights of holders of outstanding options without their
consent.

1999 EMPLOYEE STOCK PURCHASE PLAN


     Our board of directors adopted, and the shareholders approved on May 17,
1999, the 1999 Employee Stock Purchase Plan. A total of 361,200 shares of our
common stock are reserved for issuance under the plan, which will become
effective on September 1, 1999.



     The plan is intended to qualify under Section 423 of the Internal Revenue
Code and provides for six-month offering periods. Each offering period includes
one purchase period.


     Employees are generally eligible to participate if they are employed by us
or a participating subsidiary for at least 20 hours per week and more than five
months in any calendar year. However, the plan does not permit an employee to
participate if the employee either:


     - immediately after the grant, owns shares controlling 5% or more of the
       total combined voting power of our shares or



     - has the right to purchase more than $25,000 worth of our shares under all
       of our employee stock purchase plans in each calendar year.



The plan permits employees to purchase common stock through payroll deductions
of up to 10% of the employee's base earnings. The maximum number of shares an
employee may purchase during a single purchase period is 4,300 shares.



     The price for shares purchased under the plan is generally 85% of the fair
market value of the shares (1) at the beginning of the offering period or (2) at
the end of the offering period, whichever is less. Employees may end their
participation at any time during a offering period, and we will repay their
payroll deductions as of the date they stop participating. Participation ends
automatically upon termination of employment with us.



     Rights granted under the plan are generally not transferable by an employee
other than by will or the laws of descent and distribution. In the event that we
merge with or into another corporation and we are not the surviving corporation
or sell substantially all of our assets, each outstanding right under the plan
will be automatically exercised to the extent of existing payroll deductions as
of the effective date of the merger or asset sale.


     The board of directors has the authority to terminate or amend the plan,
however, the shareholders must approve any amendment that will increase the
total number of shares for which rights may be granted. The shareholders must
also approve any amendment that is required by reason of section 423 of the
Internal Revenue Code. The plan will terminate automatically ten years from its
effective date unless it is terminated sooner by the board.

and entered into a consulting agreement with Grisanti, Galef & Goldress. Under
the consulting agreement, we retained Grisanti, Galef & Goldress to provide
services for three years beginning on August 1, 1992. We agreed to pay
consulting fees of $360,000 per year and bonus fees of up to $120,000 per year.
In addition, we granted Grisanti, Galef & Goldress an option to purchase up to
215,000 shares of our common stock at an exercise price of $5.35 per share. In
October 1994, we agreed to reduce the exercise price of the option to $1.51 per
share.



     We renewed our agreement with Grisanti, Galef & Goldress effective as of
August 1, 1995, extending the term for five more years. We agreed to continue
paying consulting fees of $360,000 per year and bonus fees up to $120,000 per
year. We paid bonus fees of $120,000 during 1997 and $120,000 during 1998. We
also agreed in 1995 to extend the 215,000-share stock option so that it now
expires on August 1, 2002.



     Effective January 1, 1999, the consulting agreement was amended to
discharge our remaining obligation to pay consulting fees or bonuses to
Grisanti, Galef & Goldress, in exchange for a grant to Mr. Goldress of options
to purchase 21,500 shares of our common stock under our 1997 Stock Option Plan.
Also on that date, Mr. Suttle became a Rockford employee under the terms of a
formal employment agreement. The consulting agreement as amended January 1,
1999, gives us the right, but not the obligation, to retain Grisanti, Galef &
Goldress to provide consulting services.


SUTTLE/BARTOL OPTION AGREEMENT


     Mr. Suttle holds an option to purchase 795,500 shares of our common stock
from Monument Investors Limited Partnership, a family partnership controlled by
two of our directors, Messrs. N. and T. Bartol. This option was originally
granted to Mr. Suttle effective August 1, 1992 and fully vested on August 1,
1995 as consideration for his agreement to serve as director, Chief Executive
Officer and President of Rockford for a period of not less than three years. On
August 1, 1995, the agreement was amended to extend the option period to August
1, 2002 and to revise the exercise price of the options. In connection with Mr.
Suttle's January 1, 1999 employment agreement, Monument agreed to extend the
term of the option from August 1, 2002 until December 31, 2003. The exercise
price of Mr. Suttle's options increase over time on the following schedule:

CAROLINE BARTOL NOTE


     In March 1996, we borrowed $2.0 million from Caroline Bartol, the mother of
Messrs. N. and T. Bartol. On July 1, 1996, Mrs. Bartol converted $1.0 million of
this loan into 289,562 shares of common stock and extended the $1.0 million
balance of the loan in exchange for our grant of an option to convert this
balance into shares of our common stock at a purchase price of $3.45 per share.
Mrs. Bartol assigned the loan and the option to Boulder Investors

Limited Partnership, a partnership owned by the Bartol children, which exercised
the option and converted the note into 289,562 shares on May 1, 1999.


SUTTLE EMPLOYMENT AGREEMENT

     The principal terms of our agreement with Mr. Suttle are as follows:


     - five-year term ending January 1, 2004;



     - initial base salary of $400,000 per year, subject to increases at the
       discretion of our nominating and compensation committee;



     - bonus potential of up to 50% of salary at the discretion of the board of
       directors and the compensation committee based upon our performance;



     - participation in our stock option plan, with an initial grant of 86,000
       shares at $7.67 per share as of January 1, 1999;



     - payment by us of up to $36,000 per year in premiums on a "split dollar"
       life insurance policy for Mr. Suttle's benefit; and



     - we may terminate the agreement at any time after the first year.


If we terminate without good cause, or if Mr. Suttle terminates for good reason,
we must continue to pay Mr. Suttle's base salary for 18 months after the
termination. Mr. Suttle shall not compete with us, call on any of our customers
or induce any of our employees to work for another business during the term of
the agreement and for twelve months after the later of (1) the termination date
or (2) the day we stop paying severance payments under the employment agreement.

                       PRINCIPAL AND SELLING SHAREHOLDERS


     This table contains information with respect to the beneficial ownership of
our outstanding common stock as at June 30, 1999, both before and immediately
following this offering by:


     - each of our directors and our officers listed on the Summary Compensation
       Table;

     - all executive officers and directors as a group;

     - each person who is known by us to own beneficially more than five percent
       of our outstanding common stock; and

     - each of the selling shareholders.


The following calculation of the percentage of outstanding shares is based on
4,735,201 shares of common stock outstanding as at June 30, 1999. For beneficial
ownership after the offering, the following calculation assumes conversion of
$278,953 of the 8.5% convertible subordinated debentures into 114,236 shares to
occur upon completion of the offering, conversion of 14,424 of the warrants into
14,424 shares to occur upon completion of the offering, and the issuance of
64,500 options to Ralph Godfrey at the initial public offering price to occur
upon completion of the offering and no exercise of the underwriters' over-
allotment option. Beneficial ownership is determined in accordance with the
Securities and Exchange Commission's rules and generally includes voting or
investment power with respect to securities, subject to community property laws,
where applicable. Shares of common stock subject to options, warrants and
convertible debentures that are exercisable or convertible within 60 days of May
15, 1999 are deemed to be outstanding and beneficially owned by the person
holding the option, warrant or debenture for the purpose of computing the
percentage of ownership of that person, but they are not deemed outstanding for
the purpose of computing the percentage of ownership of any other person.


     Except as otherwise noted, each of the persons or entities named in the
table below have sole voting and investment power with respect to all the shares
of common stock beneficially owned by them.

                          DESCRIPTION OF CAPITAL STOCK

AUTHORIZED CAPITAL STOCK


     As at June 28, 1999, we increased our authorized capital stock to
40,000,000 shares of common stock, $.01 par value per share. The following
summary is qualified in its entirety by reference to our articles of
incorporation and bylaws, copies of which are filed as exhibits to the
registration statement of which this prospectus is a part.


COMMON STOCK


     Holders of our common stock are entitled to one vote per share on all
matters to be voted upon by the shareholders, except for the election of
directors. The holders of common stock have cumulative voting rights with
respect to the election of directors and, as a result, minority shareholders may
be able to elect directors on the basis of their votes alone. Holders of common
stock are entitled to receive pro rata dividends as may be declared by the board
of directors out of funds legally available as dividends. In the event of our
liquidation, dissolution or winding up, holders of common stock are entitled to
share pro rata in all assets remaining after payment of liabilities. Holders of
our common stock have no preemptive, conversion or other rights to subscribe for
additional securities. There are no redemption or sinking fund provisions
applicable to our common stock. All outstanding shares of common stock are, and
all shares of common stock to be outstanding upon completion of the offering
will be, validly issued, fully paid and nonassessable.



     As at June 30, 1999, assuming the conversion of $278,953 of the 8.5%
convertible subordinated debentures into 114,236 shares and the issuance of
14,424 shares upon exercise of warrants, both to occur upon completion of this
offering, there were outstanding 4,863,861 shares of common stock, options to
purchase 1,995,981 shares of common stock, warrants to purchase 83,911 shares of
common stock and debentures convertible into 293,123 shares of common stock.
Upon completion of this offering, 7,363,861 shares of common stock will be
outstanding, assuming no exercise of the underwriters' over-allotment option and
no exercise or conversion of options, warrants or convertible debentures after
June 30, 1999.


WARRANTS


     As of the date of this prospectus, warrants to purchase 76,835 shares of
common stock at an exercise price of $0.93 per share and warrants to purchase
21,500 shares of common stock at an exercise price of $3.45 per share were
outstanding. The common stock that we will issue upon exercise of the 76,835
warrants is subject to registration rights, which are described below.


DEBENTURES


     As of the date of this prospectus, holders of the 8.5% convertible
subordinated debentures had the right to convert their debentures into 407,359
shares of our common stock at a conversion price of $2.44 per share. The common
stock that we will issue upon conversion of these debentures is subject to
registration rights, which are described below.


REGISTRATION RIGHTS


     The holders of approximately 76,835 shares of common stock, that we will
issue upon exercise of outstanding warrants, have registration rights for those
shares. Their rights are subject to conditions that are typically imposed on
registration rights. They include "piggyback" registration rights relating to
any public offering we conduct and demand registration rights exercisable on one
occasion. In order to require a demand registration, holders of at least 50% of
the warrants or of common stock obtained by prior conversion of

                                       55

the warrants must request registration and the proposed offering must be
expected to raise proceeds of at least $7.5 million.

ANTI-TAKEOVER PROVISIONS IN OUR ARTICLES OF INCORPORATION AND BYLAWS AND OPT-OUT
FROM THE ARIZONA CONTROL SHARE ACQUISITION AND BUSINESS COMBINATION STATUTE


     Articles of Incorporation and Bylaws.  Our board of directors may issue
additional shares of common stock without shareholder approval, to the extent
shares are authorized for issuance in our articles of incorporation. This may
protect the continuity of management because it gives the board of directors
power to discourage an acquisition. The board of directors may exercise this
power, subject to compliance with fiduciary duties, even if our shareholders
would receive a premium over the market price for their shares. For example, if
the board of directors decides that a takeover proposal is not in our best
interest, the board of directors could issue shares that make completion of a
takeover more difficult and more costly by:

     - diluting the voting or other rights of the proposed acquiror or insurgent
       shareholder group;

     - putting a substantial voting block in institutional or other hands that
       support the incumbent board of directors; or

     - effecting an acquisition that complicates or precludes the takeover.

     Our articles of incorporation require approval of any amendments by a
two-thirds vote of the outstanding shares. This requirement limits the ability
of shareholders to change the restrictions described above by voting to amend
our articles of incorporation.

     Our bylaws provide for our board to have from two to eleven directors.
Directors are elected at the annual shareholders meeting, with each director
holding office until his or her successor is elected. Our directors are not
classified and are elected annually. Our articles of incorporation require that:

     - two-thirds of our board of directors approve any increase in the size of
       our board of directors;

     - the shareholders may remove a director only for cause; and

     - only the board of directors may fill a vacancy on the board of directors.

These requirements may restrict the ability of a hostile bidder to gain control
of our board of directors by limiting the bidder's right to add new directors or
replace existing directors.

     Our bylaws provide that special meetings of shareholders may be called only
by our President or a majority of the board of directors. Shareholders may not
call shareholders meetings and, under Arizona law, may act by written consent in
lieu of a meeting only if all shareholders sign the consent. Our bylaws require
that shareholders who wish to place an item on the agenda for a shareholders
meeting, or who wish to nominate a person for election as a director, must give
at least 30 days notice of the proposed agenda item or name of the

                                       56
<PAGE>   58

person nominated. Together, these restrictions may limit proxy contests seeking
to control us by


     - limiting shareholders' ability to call a special shareholders meeting,



     - making shareholder action by written consent impossible as a practical
       matter, and



     - giving the board of directors advance notice of hostile annual meeting
       proposals.



     These provisions are intended to enhance the likelihood of continuity and
stability in the composition of our board of directors and in the policies
formulated by them and to discourage transactions that may involve an actual or
threatened change of control of Rockford. These provisions are designed to
reduce our vulnerability to an unsolicited proposal for takeover that does not
contemplate the acquisition of all of our outstanding shares, or an unsolicited
proposal for the restructuring or sale of all or part of Rockford. These
provisions, however, could discourage potential acquisition proposals and could
delay or prevent a change in control of Rockford. These provisions may also have
the effect of preventing changes in our management.



     Opt-out from Arizona Control Share Acquisition and Business Combination
Statute.  We have opted out of the Arizona statute regulating control share
acquisitions and business combinations, A.R.S. Title 10, Chapter 23. As a
result, potential bidders are not subject to the statute's restrictions on
control share acquisitions or business combinations with us.


LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS

     Our articles of incorporation limit, to the maximum extent permitted by
Arizona law, the liability of our directors for monetary damages arising from a
breach of their duties as directors. The limitation of liability does not affect
the availability of equitable remedies such as injunctive relief or rescission.

     Our articles of incorporation require us to indemnify our directors and
officers, to the maximum extent permitted by Arizona law, against liability for
acts or omissions within the scope of their authority as directors or officers.
Indemnification is prohibited if our board of directors finds that the person's
action or omission was willful, grossly negligent, or with fraudulent or
criminal intent, or for liabilities under the Securities Act of 1933. Under
Arizona law, we may indemnify a director or officer against liability incurred
on account of service to us, if the director or officer:

     - conducted himself or herself in good faith;

     - reasonably believed that his or her conduct (1) if in an official
       capacity, was in our best interests or (2) if in any other capacity, was
       not opposed to our best interests;

     - in the case of any criminal proceeding, had no reasonable cause to
       believe that his or her conduct was unlawful; and

     - did not improperly receive personal benefit.

     Before completing this offering, we intend to enter into indemnification
agreements with each of our directors. These agreements will generally obligate
us to indemnify them for liability incurred by them as a result of their service
as directors, unless (1) their liability arises as a result of their fraud,
deliberate dishonesty or willful misconduct or (2) Arizona law prohibits
indemnification. Prior to completing this offering, we will obtain liability
insurance for our directors.

                        SHARES ELIGIBLE FOR FUTURE SALE


NO PRIOR MARKET


     We have not had any public market for our common stock before this
offering. If our shareholders decide to sell many of their shares in the public
market, the price of our shares could go down and we could find it hard to raise
capital by selling more shares.


OUTSTANDING SHARES AND REGISTRATION



     After this offering, we will have 7,363,861 shares of common stock
outstanding, assuming no exercise of the underwriters' over-allotment option and
no exercise or conversion of outstanding options, warrants and convertible
debentures after May 15, 1999 other than the conversion of $278,953 of the 8.5%
convertible subordinated debentures into 114,236 shares and the issuance of
14,424 shares upon exercise of warrants, both to occur upon completion of this
offering. Of these shares, the 3,387,824 shares sold in this offering will be
freely tradable without restriction or further registration under the Securities
Act of 1933, except that shares held by our "affiliates" will be subject to the
restrictions of Rule 144 under the Securities Act of 1933 described below. The
remaining 3,967,037 outstanding shares of common stock will be "restricted
securities" under Rule 144.



LOCK-UP AGREEMENTS



     Our directors, executive officers and other shareholders, holding 3,601,919
shares in the aggregate, have agreed that they will not sell, directly or
indirectly, any shares of common stock without the prior written consent of Dain
Rauscher Wessels for a period of 180 days after the date of this prospectus.
Subject to these lock-up agreements, our outstanding shares of common stock will
be eligible for sale in the public market as follows:

SALES RESTRICTIONS



     In general under Rule 144, if restricted shares were purchased from us (or
any affiliate of ours) more than one year ago, their owner may sell them in
"brokers' transactions" or to market makers. The owner may not sell, in any
three-month period, more than the greater of (1) one percent of our
then-outstanding shares of common stock (approximately           shares
immediately after this offering), or (2) the average weekly trading volume in
our common stock during the four calendar weeks before a Form 144 notice of sale
is filed with the Securities Exchange Commission at its principal office in
Washington D.C. and to any national securities exchange on which such securities
are traded. The Form 144 shall be signed by the person for whose account the
securities are to be sold and shall be transmitted for filing concurrently with
either the placing with a broker of an order to execute a sale of securities in
reliance on Rule 144 or the execution directly with a market maker of such a
sale. Neither the filing of such notice nor the failure of the Commission to
comment thereon shall be deemed to preclude the Commission from taking any
action it deems necessary or appropriate with respect to the sale of the
securities referred to in such notice. The owner may make sales only if current
public information is available about us.


     If the restricted shares were purchased from us (or any affiliate of ours)
more than two years ago, then their owner may sell them under Rule 144(k)
without regard to the volume limitations or manner of sale, public information
or notice of sale requirements of Rule 144. This does not apply if the owner was
an affiliate of ours at any time during the 90 days before the sale.


STOCK OPTION RESTRICTIONS


     Under Rule 701 under the Securities Act of 1933 persons who purchase shares
from us upon exercise of options granted before the date of this prospectus may
sell their shares in the public markets beginning 90 days after the date of this
prospectus. They make the sales in reliance on Rule 144 without having to comply
with its holding period requirements and, if they are not affiliates, without
having to comply with the rule's volume limitations, public information and
notice of sale requirements.

     We intend to file one or more registration statements under the Securities
Act of 1933, covering the shares of common stock reserved for issuance under our
1994 and 1997 stock option plans. We plan this filing within 90 days after the
date of this prospectus. The registration statements will become effective upon
filing, thus permitting the resale of option shares in the public markets,
without restriction under the Securities Act of 1933 other than the limitations
applicable to affiliates or the 180-day lock ups described above.

     See "Description of Capital Stock -- Registration Rights" for a description
of certain registration rights with respect to our common stock.

                                  UNDERWRITING


     The underwriters named below, acting through their representatives, Dain
Rauscher Wessels, a division of Dain Rauscher Incorporated, and Needham &
Company, Inc. have agreed, subject to the terms and conditions set forth in the
underwriting agreement, to purchase from us and the selling shareholders the
number of shares of common stock listed opposite their names below. The
underwriters are committed to purchase and pay for all such shares if any are
purchased, subject to the conditions stated in the underwriting agreement.

</TABLE>



     The representatives have advised us and the selling shareholders that the
underwriters propose to offer the shares of common stock to the public at the
offering price set forth on the cover page of this prospectus and to selected
dealers at such price less a concession of not in excess of $     per share, of
which $          may be reallowed to other dealers. After this offering, the
public offering price concession and reallowance to dealers may be reduced by
the representatives. No such reduction will change the amount of proceeds to be
received by us and the selling shareholders as set forth on the cover page of
this prospectus.



     The underwriting agreement contains covenants of indemnity among the
underwriters, us and the selling shareholders against civil liabilities,
including liabilities under the Securities Act and liabilities arising from
breaches of representations and warranties contained in the underwriting
agreement.



     We have granted an option to the underwriters to purchase up to 508,174
additional shares of common stock. These options may be exercised at any time up
to 30 days after the date of this prospectus. The option entitles the
underwriters to purchase the additional shares of common stock at the same price
per share as the 3,387,824 shares being sold in this offering. If the
underwriters exercise the option, each of the underwriters must purchase
approximately the same percentage of additional shares from us that they
purchased in the primary offering. The underwriters may purchase these shares
only to cover over-allotments made in connection with this offering. If
purchased, the additional shares will be sold by the underwriters on the same
terms as those on which the 3,387,824 shares are being sold.



     The price of the shares of common stock purchased by the underwriters will
be the public offering price set forth on the cover page of the prospectus less
the following underwriting discounts and commissions to be paid by us and the
selling shareholders.

     We will also pay the total expenses of this offering.



     Our officers, directors and other shareholders have agreed not to sell,
transfer, grant any third party the right to purchase, or otherwise dispose of
any shares of common stock or other securities that they own or acquire, other
than shares of common stock acquired in open market transactions, for a period
of 180 days after the date of this prospectus without


                                       61
<PAGE>   63


the prior written consent of the underwriters. This 180-day period is known as
the lock-up period. The representatives may, without notice and in their sole
discretion, allow any officer or director to dispose of common stock or other
securities prior to the expiration of the lock-up period. There are, however,
currently no agreements between the underwriters and any of our officers or
directors allowing any sale.



     In addition, we have agreed that we will not issue, sell, offer to sell, or
otherwise dispose of any shares of our common stock or other securities during
the lock-up period without the prior consent of the underwriters. This agreement
does not include shares of common stock or other securities issued pursuant to
employee stock option plans, employee stock purchase plans, or common stock or
other securities outstanding on the date of this prospectus. However, we have
agreed that employee stock options issued during the lock-up period to our
officers and directors may not be exercised prior to the expiration of the
lock-up period. Any shares of common stock issued to our officers and directors
during the lock-up period pursuant to the exercise of stock options or other
securities outstanding on the date of this prospectus shall bear a restrictive
legend restricting the transfer of those shares during the lock-up period.



     The underwriters have advised us that in connection with this offering,
some persons participating in this offering may engage in transactions that may
have the effect of stabilizing or maintaining the market price of the common
stock at a level above that which might otherwise prevail in the open market.
These transactions may include stabilizing bids, syndicate covering transactions
and the imposition of penalty bids. A "stabilizing bid" is a bid for or the
purchase of common stock on behalf of the underwriters for the purpose of
preventing or retarding a decline in the market price of the common stock. A
"syndicate covering transaction" is the bid for or the purchase of the common
stock on behalf of the underwriters to reduce a short position incurred by the
underwriters in connection with this offering. A "penalty bid" is an arrangement
permitting the representatives to reclaim the selling concession otherwise
accruing to an underwriter or syndicate member in connection with the offering
if the common stock originally sold by such underwriter or syndicate member is
purchased by the representatives in a syndicate covering transaction and has
therefore not been effectively placed by such underwriter or syndicate member.
The representatives have advised us that these transactions may be affected on
the Nasdaq SmallCap Market, Nasdaq National Market or otherwise and, if
commenced, may be discontinued at any time.



                                 LEGAL MATTERS



     The validity of the common stock offered by this prospectus will be passed
upon for us by Steptoe & Johnson LLP, Phoenix, Arizona. Certain legal matters
relating to this offering will be passed upon for the underwriters by Brobeck,
Phleger & Harrison LLP, Austin, Texas.

The Board of Directors and Stockholders
Rockford Corporation

     We have audited the accompanying consolidated balance sheets of Rockford
Corporation and subsidiaries (Rockford) as of December 31, 1997 and 1998, and
the related consolidated statements of operations, shareholders' equity, and
cash flows for the year ended September 30, 1996, the three months ended
December 31, 1996, and the years ended December 31, 1997 and 1998. These
consolidated financial statements are the responsibility of Rockford's
management. Our responsibility is to express an opinion on these consolidated
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 consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Rockford Corporation and subsidiaries at December 31, 1997 and 1998, and the
consolidated results of their operations and their cash flows for the year ended
September 30, 1996, the three months ended December 31, 1996, and the years
ended December 31, 1997 and 1998, in conformity with generally accepted
accounting principles.

                     ROCKFORD CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                   (The information for the six months ended


                      June 30, 1998 and 1999 is unaudited)


1.  ACCOUNTING POLICIES

  Organization and Description of Business


     Rockford Corporation and subsidiaries ("Rockford") is a designer,
manufacturer and distributor of high performance car audio systems under the
"Rockford Fosgate" brand name for the worldwide car audio aftermarket. Rockford
also sells professional audio products under the "Hafler" brand name. Rockford
was organized and incorporated under the laws of the State of Arizona on July
22, 1980, and has manufacturing facilities in Tempe, Arizona and Grand Rapids,
Michigan; warehousing operations in Germany and Singapore; and sales and
warehousing operations in Japan.



     During April 1999, the Board of Directors authorized Rockford to file a
registration statement for an initial public offering of shares of its common
stock. On June 28, 1999 the shareholders approved an increase in the number of
authorized common shares to 40,000,000.


  Interim Financial Information


     The consolidated financial statements as of June 30, 1999 and for the six
months ended June 30, 1998 and 1999 are unaudited, but include all adjustments
(consisting only of normal recurring adjustments) that Rockford considers
necessary for a fair presentation of financial position as of such date and
results of operations and cash flows for such period. Operating results for the
six months ended June 30, 1999 are not necessarily indicative of the results
that may be expected for any future period.


  Principles of Consolidation

     The consolidated financial statements include the accounts of Rockford and
its wholly owned subsidiaries in Germany and Singapore and its majority (90
percent) owned subsidiary in Japan. Significant intercompany accounts and
transactions have been eliminated in consolidation.

  Cash and Cash Equivalents

     Cash and cash equivalents consist of cash and highly liquid investments
with remaining maturities of three months or less when acquired and which are
readily convertible to cash. Rockford's investments have consisted of commercial
paper, certificates of deposit with original maturities of three months or less
and money market accounts.

  Fair Value of Financial Instruments

     At December 31, 1998, Rockford has the following financial instruments:
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses, capital lease obligations, notes payable and long-term debt. The
carrying value of cash and cash equivalents, accounts receivable, accounts
payable and accrued expenses approximates their fair value based on the
liquidity of these financial instruments or based on their short-term nature.
The carrying value of capital lease obligations, notes payable and long-term
debt approximates fair value based on the market interest rates available to
Rockford for debt of similar risk and maturities.

                     ROCKFORD CORPORATION AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

                   (The information for the six months ended


                      June 30, 1998 and 1999 is unaudited)


  Accounts Receivable


     Rockford sells its products principally to car audio and professional audio
dealers primarily in North America, South America, Europe and Asia. At December
31, 1997, 1998 and June 30, 1999, net accounts receivable includes approximately
$3,213,000, $2,958,000 and $4,384,000, respectively, due from overseas
businesses.



     Rockford also offers a prompt pay discount for certain invoices paid under
40 to 60 days of issuance and has included in its allowance for accounts
receivable at December 31, 1997, 1998 and June 30, 1999 approximately $162,000,
$262,000 and $418,000, respectively, with respect to accounts using such
discounts after the period-end.


  Inventories

     Inventories consist principally of raw materials of electronic and
mechanical components used in the manufacturing of amplifier and speaker
systems, and finished goods. Inventories are carried at the lower of cost or
market using the first-in, first-out (FIFO) method.

  Property and Equipment

     Property and equipment is stated at cost. Depreciation and amortization are
computed principally on the straight-line method for financial reporting
purposes over a three-to-five year life. Leasehold improvements are amortized on
the straight-line method over the shorter period of the lease term or the
estimated useful life of the asset.

sheet date. Statement of operations amounts have been translated using the

grants. Stock option grants to non-employees are charged to expense based upon
the fair value of the options granted.

generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the consolidated financial
statements and accompanying notes. Actual results could differ from those
estimates.

Comprehensive Income. In adopting the new requirements for calculating income,
items of other comprehensive income have been presented in the equity section of

2.  ACQUISITIONS



     On June 30, 1999 Rockford completed its acquisition of all of the common
stock of Lightning Audio. Under the terms of the acquisition Rockford paid
$1,550,000 in cash and recorded an additional $50,000 of purchase consideration
obligations for a total purchase price of $1.6 million. Under the terms of the
acquisition Rockford could pay up to $600,000 more over the next two years based
upon the subsequent performance of Lightning Audio. Rockford recorded
approximately $1,635,000 of goodwill which it plans to amortize over 15 years.
The purchase price allocation has been based on the best information available
at the time and may be subject to further revisions as management finalizes its
analysis of the assets acquired and liabilities assumed. The acquisition has
been accounted for under the purchase method of accounting and, accordingly, the
results of operations of Lightning Audio will be included in Rockford's
consolidated results of operation beginning on July 1, 1999. The acquisition was
not significant under the requirements of the Securities and Exchange
Commission.



     On June 14, 1999 Rockford issued its 21,500 shares of treasury stock in
exchange for the 10% interest in its Japanese subsidiaries not held by Rockford.
The Company accounted for the acquired interest using the estimated fair value
of the common stock issued of $7.67 per share which resulted in the elimination
of minority interest and the recording of approximately $155,000 of goodwill.

                      June 30, 1998 and 1999 is unaudited)

     Annual maturities of notes payable and long-term debt for the years
succeeding December 31, 1998 are $1,841,000 in 1999, $12,601,000 in 2000, $-0-
in 2001 and $995,000 in 2002. Interest payments were approximately $1,705,000
and $1,520,000 for the years ended December 31, 1997 and 1998, respectively.

     At December 31, 1998, Rockford has $5,999,000 available under its revolving
line of credit and $1,000,000 available for financing equipment under its credit
arrangement with its primary lender.


     Rockford's $17,000,000 revolving line of credit, its 10.5 percent
subordinated senior notes payable and its 8.5 percent convertible subordinated
debentures contain covenants which place various restrictions on financial
ratios, levels of indebtedness, and capital expenditures, among other things.
Rockford issued warrants in April of 1997 to purchase 21,500 shares of common
stock at $3.45 in conjunction with this credit facility which expire on June 1,
2007.



     During 1996, the Company refinanced its line of credit prior to maturity.
Consequently, a loss on the early extinguishment of debt, consisting of
prepayment premiums, deferred loan costs, and related expenses of $327,000 (net
of tax benefit of approximately $161,000) is reflected as an extraordinary item
in the consolidated statements of operations.

8.  COMMON STOCK GRANTS AND OPTIONS



     The Board of Directors of Rockford prior to 1995 granted a certain
consulting firm, which provided chief executive officer services to Rockford
until January 1, 1999, options to purchase 215,000 shares of its authorized but
unissued common stock at a price of $1.51 per share, protected against dilution,
as defined, and expiring in August 2002. The price per share exceeded the fair
value at the date of the grant. The stock options are fully vested at December
31, 1998.


     Rockford has elected to follow APB 25 and related Interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under SFAS No. 123, Accounting
for Stock-Based Compensation, requires use of option valuation models that were
not developed for use in valuing employee stock options. Under APB 25, because
the exercise price of Rockford's employee stock options equals the market price
of the underlying stock on the date of grant, no compensation expense is
recognized.


     Rockford has provided stock option plans for certain employees and
directors under its 1994 and 1997 stock option plans. Under the plans, options
to purchase common stock of Rockford will be granted to certain employees and
directors at the fair value of the underlying common stock. The options
generally have a term of ten years and become exercisable over three years
commencing on the date of the grant. Options granted prior to December 31, 1996
will vest 100 percent upon an initial public offering or merger or acquisition
of Rockford. Up to 2,150,000 shares are reserved and may be offered under these
plans. Under certain circumstances, Rockford has the right to repurchase common
stock acquired under the options at the fair value price.



     Pro forma information regarding net income and earnings per share is
required by SFAS No. 123, which also requires that the information be determined
as if Rockford has accounted for its employee stock options granted subsequent
to December 31, 1994 under the fair value method of that Statement. The fair
value for these options was estimated at the date of grant using a minimum value
pricing model with the following weighted-average assumptions for each period:

10.  CONTINGENCIES



     Rockford is a party to legal proceedings which arise out of the ordinary
course of business. Based upon advice from outside legal counsel, management is
of the opinion that these matters will have no material effect on Rockford's
consolidated financial position, results of operations or cash flows.



11.  EMPLOYEE BENEFIT PLANS


     Rockford has a 401(k) Retirement Savings Plan (the Plan) covering
substantially all employees who have completed six consecutive months of service
without regard to hours of service. Under the terms of the Plan, employees may
make voluntary contributions, subject to Internal Revenue Service limitations.
Rockford will match employee contributions up to three percent of the employee's
annual compensation. Additional contributions to the Plan can be made at the
discretion of the Board of Directors. Contributions to the Plan during the year
ended September 30, 1996, the three months ended December 31, 1996 and the years
ended December 31, 1997 and 1998 were approximately $219,000, $46,000, $237,000
and $296,000, respectively.


     On May 17, 1999 the shareholders approved the adoption of the 1999 Employee
Stock Purchase Plan to be effective September 1, 1999. Under the Plan, 361,200
shares of common stock have been reserved for issuance.



12.  SEGMENT INFORMATION


     Rockford operates its business under the car audio and professional audio
product lines. For each of the years ended December 31, 1997 and 1998, the

(a) Revenues are attributed to geographic regions based on the location of
    customers.


     Rockford had no customers who accounted for more than 10 percent of net
sales for all periods presented except for the six months ended June 30, 1999 in
which sales to one customer accounted for 22.7 percent of that period's net
sales. Rockford's long-lived assets outside of the United States are not
significant.



13.  SUBSEQUENT EVENTS



     Effective           , 1999, Rockford executed a 4.3-for-1 common stock
split. All share information in the financial statements has been restated to
reflect the effect of the stock split.



     Effective with the successful completion of its initial public offering,
Rockford plans to grant options to purchase 64,500 shares of common stock at the
offering price to a newly elected member of its board of directors.

Text in upper left: There is a human filter in the world of music. Sitting
somewhere between the creative musician in the recording studio, and the
passionate listener in a living room or vehicle. That filter is the professional
sound engineer, the person that makes a living recording, mixing, or
broadcasting the music and movie soundtracks that we hear everyday. We believe
Hafler is the brand of choice among these working professionals and the aspiring
professionals.



Moving beyond the amplifier niche, in 1996 Hafler introduced the TRM Series of
powered monitors and powered subwoofers. Amplifier electronics manufactured in
Tempe and speaker components in Grand Rapids.

Text in middle right: Lightning Audio assaults the car audio accessory business
with battery clamps, capacitors, and speaker wire. Pretty boring stuff, but not
with Lightning Audio. Gen Y consumers now have a brand that is cool to own, but
less costly than Rockford Fosgate. We believe that Lightning Audio consumers
are proud to claim us as "their brand" and show off what is underneath carpets,
inside trunks, or under the hood of their car or truck.


We believe Lightning Audio will allow Rockford to grow by expanding the
Lightning Audio product mix into the amplifier and speaker categories at lower
price points than Rockford Fosgate and by capitalizing on new distribution
channels.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Our articles of incorporation limit, to the maximum extent permitted by
Arizona law, the liability of our directors for monetary damages arising from a
breach of their duties as directors. The limitation of liability does not affect
the availability of equitable remedies, such as injunctive relief or rescission.

     Our articles of incorporation require us to indemnify our directors and
officers, to the maximum extent permitted by Arizona law, against liability
arising against them for acts or omissions within the scope of their authority
as directors or officers. Indemnification is prohibited if our board of
directors finds that the person's action or omission was willful, grossly
negligent, or with fraudulent or criminal intent, or for liabilities under the
Securities Act of 1933. Under Arizona law, we may indemnify a director or
officer against liability incurred on account of service to us, if the director
or officer:

     - conducted himself or herself in good faith;

     - reasonably believed that his or her conduct (1) if in an official
       capacity, was in our best interests or (2) if in any other capacity, was
       not opposed to our best interests;

     - in the case of any criminal proceeding, had no reasonable cause to
       believe that his or her conduct was unlawful; and

     - did not improperly receive personal benefit.

     Before completing this offering, we intend to enter into indemnification
agreements with each of our directors. These agreements will generally obligate
us to indemnify them for liability incurred by them as a result of their service
as directors, unless (1) their liability arises as a result of their fraud,
deliberate dishonesty or willful misconduct or (2) Arizona law prohibits
indemnification. Prior to completing this offering on the effective date of this
registration statement, we will have obtained liability insurance for our
directors.

     Reference is made to Section 7 of the underwriting agreement to be filed as
an exhibit to the registration statement, indemnifying our officers and
directors against certain liabilities.

below listed unregistered securities. These issuances were deemed exempt from
registration under the Securities Act of 1933 in reliance on Rule 701 under such
Act or Section 4(2) of such Act because they were made either under a written
compensatory benefit plan established by us for the participation of our
employees or transactions by us not involving a public offering.



          1.  In 1996 and 1997, we issued 19,887 shares to several employees who
     exercised stock options pursuant to our 1994 and 1997 Stock Option Plans.



          2.  In March 1996, we borrowed $2.0 million from Caroline Bartol. On
     July 1, 1996 she converted $1.0 million of this loan into 289,562 shares of
     Common Stock.



          3.  On May 1, 1999, we issued 289,562 shares of our Common Stock to an
     entity controlled by two of our directors in connection with the conversion
     of a $1,000,001 loan.



          4.  On April 23, 1997, we issued to Vrolyk Partnership 97-A a warrant
     for 21,500 shares with an exercise price of $3.45 per share, as
     compensation for services rendered in connection with arranging our $20.0
     million credit facility.



          5.  During May and June, 1999 we issued 12,147 shares to two employees
     who exercised stock options pursuant to our 1994 and 1997 stock option
     plans.



          6.  During June 1999 we issued 748 shares to a warrantholder who
     exercised his warrant conversion rights.



          7.  During June 1999 we issued 21,500 shares to the owner of 10% of
     our Japanese subsidiary in order to purchase his interest. As a result of
     this issuance, we now own 100% of our Japanese subsidiary.



          8.  We have, from time to time, granted stock options to employees.
     The following table sets forth certain information regarding such grants:

ITEM 17.  UNDERTAKINGS

     We hereby undertake to provide to the underwriter at the closing specified
in the underwriting agreements certificates in such denominations and registered
in such names as required by the underwriter to permit prompt delivery to each
purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended, may be permitted to our directors, officers and controlling
persons pursuant to the Act, our articles of incorporation or our bylaws, the
underwriting agreement or otherwise, we have been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act of 1933, as amended, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by us of expenses incurred or paid by
one of our directors, officers or controlling persons 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 hereunder,
we will, unless in the opinion of our counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933, as amended, and will be governed by the
final adjudication of such issue.

     We hereby undertake that for purposes of determining any liability under
the Securities Act of 1933, as amended, 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 us pursuant to Rule
424(b)(1) or (4) or 497(h) under the Securities Act of 1933, as amended, shall
be deemed to be part of this registration statement as of the time it was
declared effective. We further undertake that for the purpose of determining any
liability under the Securities Act of 1933, as amended, 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 this
offering of such securities at that time shall be deemed to be the initial BONA
FIDE offering thereof.

on its behalf by the undersigned, thereunto duly authorized, in the City of

1933, as amended, and all post-effective amendments thereto, and to file the
same, with all exhibits thereto and all documents in connection therewith, with

                                  July 8, 1999

Rockford Corporation
648 South River Drive
Tempe, Arizona  85281

         Re:      Registration Statement on Form S-1 (No. 333-79285)

Gentlemen:


                  In connection with the registration under the Securities Act
of 1933, as amended, of 3,895,998 shares of Common Stock, par value $0.01 per
share, of Rockford Corporation (the "Company"), including 508,174 shares as to
which the Underwriters have the option to purchase to cover overallotments, if
any, we have examined the Registration Statement on Form S-1 filed by you with
the Securities and Exchange Commission on May 26, 1999 (No. 333-79285), as
amended through the date hereof (the "Registration Statement"), corporate
records, certificates of public officials, Company officers and such other
documents as we deemed appropriate or necessary for the purpose of rendering
this opinion.



                  Based on the foregoing, it is our opinion that the 3,895,998
shares of Common Stock of the Company covered by the Registration Statement have
been duly authorized and, when the 3,895,998 shares to be sold by the Company
and the Selling Stockholders identified therein have been issued and sold in
accordance with the terms set forth in the Registration Statement, will be
validly issued, fully paid and non-assessable.


                  We consent to the filing of this opinion as an exhibit to the
Registration Statement, and to the reference to our firm under the caption
"Legal Matters" in the Prospectus contained in the Registration Statement.

                                Very truly yours,




                                STEPTOE & JOHNSON

                                                                    EXHIBIT 10.3




                              ROCKFORD CORPORATION

                          EMPLOYEE STOCK PURCHASE PLAN

         1.       ESTABLISHMENT OF PLAN.

                  Rockford Corporation, an Arizona corporation (the "Company"),
proposes to grant options ("Options") for purchase of the Company's common
stock, $1 par value ("Common Stock"), to eligible employees of the Company and
its Designated Subsidiaries (as hereinafter defined) pursuant to this 1999
Employee Stock Purchase Plan (this "Plan"), as amended and restated on May 17,
1999. For purposes of this Plan, "parent corporation" and "subsidiary"
(collectively, "Subsidiaries") shall have the same meanings as "parent
corporation" and "subsidiary corporation" set forth in Sections 424(e) and
424(f), respectively, of the Internal Revenue Code of 1986, as amended (the
"Code"). The Company intends this Plan to qualify as an "employee stock purchase
plan" under Section 423 of the Code (including any amendments or successor
provisions to such Section), and this Plan shall be so construed. Any term not
expressly defined in this Plan but defined for purposes of Section 423 of the
Code shall have the same definition therein.

         2.       STOCK SUBJECT TO PLAN.

                  A total of 84,000 shares of the Common Stock is reserved for
issuance under this Plan. Such number shall be subject to adjustments effected
in accordance with Section 16 of this Plan. Any shares of Common Stock that have
been made subject to an Option that cease to be subject to the Option (other
than by means of exercise of the Option), including, without limitation, in
connection with the cancellation or termination of an Option, shall again be
available for issuance in connection with future grants of Options under this
Plan.
<PAGE>   2
         3.       PURPOSE.

                  The purpose of this Plan is to provide employees of the
Company and its designated subsidiaries, as that term is defined in Section 5 of
this Plan ("Designated Subsidiaries"), with a convenient means of acquiring an
equity interest in the Company through payroll deductions, to enhance such
employees' sense of participation in the affairs of the Company and
Subsidiaries, and to provide an incentive for continued employment.

         4.       ADMINISTRATION.

                  This Plan shall be administered by the Compensation Committee
("Committee") appointed by the Company's Board of Directors (the "Board").
Subject to the provisions of this Plan and the limitations of Section 423 of the
Code or any successor provision in the Code, the Committee shall have exclusive
authority, in its discretion, to determine all matters relating to Options
granted under this Plan, including all terms, conditions, restrictions, and
limitations of Options; provided, however, that all participants granted Options
under an offering pursuant to this Plan shall have the same rights and
privileges within the meaning of Code Section 423(b)(5) except as required by
applicable law. The Committee shall also have exclusive authority to interpret
this Plan and may from time to time adopt rules and regulations of general
application for this Plan's administration. The Committee's exercise of
discretion and interpretation of this Plan, its rules and regulations, and all
actions taken and determinations made by the Committee pursuant to this Plan,
shall be conclusive and binding on all parties involved or affected. The
Committee may delegate administrative duties to such of the Company's officers
or employees as it so determines (provided that no such delegation may be made
that would cause the purchase of Common Stock by participants under this Plan to
cease to be exempt from Section 16(b) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act")). All expenses incurred


                                      -2-
<PAGE>   3
in connection with the administration of this Plan shall be paid by the Company
and the Designated Subsidiaries; provided, however, that the Committee may
require a participant to pay any costs or fees in connection with the sale by
the participant of shares of Common Stock acquired under this Plan or in
connection with the participant's request for the issuance of a certificate for
shares of Common Stock held in the participant's account under the Plan.

         5.       ELIGIBILITY.

                  Any employee of the Company or the Designated Subsidiaries is
eligible to participate in the Plan for any Offering Period (as hereinafter
defined) under this Plan except the following:

                  (a) employees who have not been continuously employed by the
Company or Subsidiaries from the date of hire or rehire or of return from an
unapproved leave of absence for a period of at least 60 days before the
beginning of such Offering Period;

                  (b) employees who are customarily employed for less than 20
                  hours per week;

                  (c) employees who are customarily employed for not more than
five months in a calendar year;

                  (d) employees who, together with any other person whose stock
would be attributed to such employee pursuant to Section 424(d) of the Code, own
stock or hold options to purchase stock possessing five percent or more of the
total combined voting power or value of all classes of stock of the Company or
any of its Subsidiaries or who, as a result of being granted Options under this
Plan, would own stock or hold options to purchase stock possessing five percent
or more of the total combined voting power or value of all classes of stock of
the Company or any of its Subsidiaries; and



                                      -3-
<PAGE>   4
                  (e) employees who are citizens of a foreign country which
prohibits foreign corporations from granting stock options to any of its
citizens.

                  For all purposes of this Plan, the term Designated
Subsidiaries shall mean all Subsidiaries (including the Company); provided that
any Designated Subsidiary shall cease to be a Designated Subsidiary on the
earlier of (i) the date such Designated Subsidiary ceases for any reason to be a
"parent corporation" or "subsidiary corporation" as defined in Sections 424(e)
and 424(f), respectively, of the Code, or (ii) the date the Committee or the
Board determines that such Subsidiary shall no longer be a Designated Subsidiary
for purposes of the Plan.

6.       OFFERING AND OFFERING PERIODS.

                  (a) For purposes of this Plan, the Offering Periods of this
Plan (an "Offering Period") shall be of periods not to exceed the maximum period
permitted by Section 423 of the Code.

                  (b) Until determined otherwise by the Committee or the Board,
or unless paragraph (c) applies, Offering Periods shall be of six months'
duration, and the first Offering Period shall begin on September 1, 1999. The
first day of each Offering Period is referred to as the "Offering Date." The
last day of each Offering Period is referred to as the "Purchase Date." Unless
determined otherwise by the Committee or the Board, Offering Periods shall begin
on the first day of the month every 6 months after the first day of the prior
Offering Period. During an Offering Period, payroll deductions of the
participants are accumulated under this Plan. Subject to the requirements of
Section 423 of the Code, the Committee or the Board shall have the power to
change the duration of Offering Periods with respect to future offerings if such
change is announced at least 30 days prior to the first day of the first
Offering Period to be affected by such change.


                                      -4-
<PAGE>   5
         7.       PARTICIPATION IN THIS PLAN.

                  Eligible employees may become participants in an Offering
Period under this Plan on the first Offering Date after satisfying the
eligibility requirements by delivering an enrollment form provided by the
Company at the time and in the manner required by the Committee, under such
rules as are consistently applied to all eligible employees with respect to a
given Option. Once an employee becomes a participant in the Plan with respect to
an Offering Period, such employee will automatically participate in the Offering
Period commencing immediately following the last day of the prior Offering
Period unless the employee withdraws from this Plan or terminates further
participation in the Offering Period as set forth in Sections 13 and 14 below,
or otherwise becomes ineligible to participate. Such participant is not required
to file any additional enrollment form in order to continue participation in
this Plan, except that the Committee may require the filing of new enrollment
forms by participants who transfer to another division of the Company or a
Designated Subsidiary.

         8.       GRANT OF OPTION ON ENROLLMENT.

                  Subject to the limitations of the Plan, enrollment by an
eligible employee in this Plan with respect to an Offering Period will
constitute the grant by the Company to such employee of an Option to purchase on
each Purchase Date up to that whole number of shares of Common Stock of the
Company, determined by dividing (a) the amount accumulated in such employee's
payroll deduction account during the Offering Period ending on such Purchase
Date by (b) the Purchase Price as that term is defined in Section 9.
Fractional shares shall not be issued under this Plan.

                                      -5-
<PAGE>   6
         9.       PURCHASE PRICE.

                  The purchase price per share (the "Purchase Price") at which a
share of Common Stock will be sold in any Offering Period shall be the lower of
(a) 85 percent of the fair market value of such share on the first day of the
Offering Period or (b) 85 percent of the fair market value of such share on the
Purchase Date; provided, however, that in no event may the purchase price per
share of Common Stock be below the par value per share of Common Stock.

                  For purposes of this Plan, the term "fair market value" on a
given date shall be the mean between the highest and lowest reported sales
prices of the Common Stock on the New York Stock Exchange Composite Tape or, if
the Common Stock is not listed on such exchange, any other national securities
exchange on which the Common Stock is listed or on NASDAQ. If there is no
reported sale price of the Common Stock on such date, then the "fair market
value" shall be measured on the next preceding trading day for which such
reported sale price is available. If there is no regular trading market for the
Common Stock, the fair market value of the Common Stock shall be as determined
by the Committee in its sole discretion, exercised in good faith. The Committee
may change the manner in which the Purchase Price is determined with respect to
future offerings (provided such determination does not have the effect of
lowering the Purchase Price to an amount less than that which would be computed
utilizing the method for determining the Purchase Price set forth in the first
paragraph of this Section 9) if such changed manner of computation is announced
at least 30 days prior to the first day of the first Offering Period to be
affected by such change.

         10.      PURCHASE OF SHARES; CHANGES IN PAYROLL DEDUCTIONS; ISSUANCE OF
                  SHARES.

                  (a) Funds contributed by each participant for the purchase of
shares under this Plan shall be accumulated by regular payroll deductions made
during each Offering Period. The deductions shall be made as a percentage of the
participant's Compensation in 1 percent increments comprising not less than 1
percent and not more than a total of 10 percent of Compensation with respect to
each Offering Period. As used herein, "Compensation" shall mean only the
participant's base salary, excluding cash bonuses, commissions, overtime and
similar items; provided, however, that, for purposes of determining a
participant's Compensation, any election by such participant to reduce his or
her regular cash remuneration under Sections 125, 401(k), or 132(f) of the Code
shall be treated as if the participant did not make such election.
"Compensation" does not include severance pay, hiring and relocation allowances,
pay in lieu of vacation, automobile allowances, imputed income arising under any
Company group insurance or benefit program, income received in connection with
stock options, or any other special items of remuneration. Payroll deductions
shall commence on the first payday following the Offering Date and shall
continue through the last payday of the Offering Period unless sooner altered or
terminated as provided in this Plan.

                  (b) A participant may lower (but not increase) the rate of
payroll deductions once during any six-month Offering Period and may increase or
decrease the rate of payroll deductions as of the start of any Offering Period.
Notwithstanding the foregoing, a participant may lower the rate of payroll
deductions to zero for the remainder of an Offering Period. Such changes may be
made by filing a new authorization for payroll deductions, at the time and in
the manner specified by the Committee, in which case the new rate shall continue
for the remainder


                                      -7-
<PAGE>   8
of the Offering Period unless changed as described herein or unless a
participant withdraws from or terminates participation in the Plan as set forth
in Section 13 or 14, in which case a new election must be made. A participant
who has decreased the rate of withholding to zero will be deemed to continue as
a participant in the Plan until the participant withdraws from the Plan in
accordance with the provisions of Section 13 or his or her participation is
terminated in accordance with the provisions of Section 14. A participant shall
have the right to withdraw from this Plan in the manner set forth in Section 13
regardless of whether the participant has exercised his or her right to lower
the rate at which payroll deductions are made during the applicable Offering
Period.

                  (c) All payroll deductions made for a participant will be
credited to his or her account under this Plan and deposited with the general
funds of the Company. No interest will accrue on payroll deductions. All payroll
deductions received or held by the Company may be used by the Company for any
corporate purpose, and the Company shall not be obligated to segregate such
payroll deductions.

                  (d) On each Purchase Date, provided that the participant has
not terminated employment in accordance with Section 14 or has not submitted a
signed and completed withdrawal form, by the time and in the manner required by
the Committee consistently applied to all eligible employees with respect to a
given Option, or the Plan has not been terminated prior to the 15th day (or if
such date is not a business day, on the immediately preceding business day) of
the last month of the Offering Period, the Company shall apply the funds then in
the participant's account to the purchase at the Purchase Price of whole shares
of Common Stock issuable under the Option granted to such participant with
respect to the Offering Period to the extent that such Option is exercisable on
the Purchase Date.



                                      -8-
<PAGE>   9
                  (e) Fractional shares cannot be purchased under this Plan and
any accumulated payroll deductions which would have been used to purchase
fractional shares during the Offering Period will be held in the participant's
account and used to purchase shares in the next Offering Period. Amounts in a
participant's account remaining after whole shares are purchased with a
participant's account will be returned to the participant promptly, without
interest, upon the earlier of the termination of the termination of the Plan or
the withdrawal of the participant from the Plan.

                  (f) During a participant's lifetime, such participant's Option
to purchase shares hereunder is exercisable only by him or her. The participant
will have no interest or voting right in shares covered by his or her Option
until such Option has been exercised.

         11.      LIMITATIONS ON RIGHTS TO PURCHASE.

                  (a) No employee shall be granted an Option to purchase Common
Stock under this Plan at a rate which, when aggregated with his or her rights to
purchase stock under all other employee stock purchase plans of the Company or
any Subsidiary which is intended to meet the requirements of Code Section 423,
exceeds $25,000 in fair market value, determined as of the applicable date of
the grant of the Option, for each calendar year in which the employee
participates in this Plan (or any other employee stock purchase plan described
in this Section 11(a)).

                  (b) The number of shares that may be purchased by any employee
with respect to an Offering Period shall not exceed 1,000 shares; provided, that
in the event the Committee or Board may specify a different limitation to be
applied in lieu of the foregoing limitation for a future Offering Period, the
number of shares that may be purchased by any employee during an Offering Period
may not exceed such other limitation.



                                      -9-
<PAGE>   10
                  (c) If the number of shares to be purchased on a Purchase Date
by all employees participating in this Plan exceeds the number of shares then
available for issuance under this Plan, then the Company will make a pro rata
allocation of the remaining shares in as uniform a manner as shall be reasonably
practicable and as the Committee shall determine to be equitable. In such event,
the Company shall give written notice of such reduction of the number of shares
to be purchased under a participant's Option to each participant affected
thereby.

                  (d) Any payroll deductions accumulated in a participant's
account which are not used to purchase stock due to the limitations in this
Section 11 shall be returned to the participant as soon as practicable after the
end of the applicable Offering Period without interest.

         12.      EVIDENCE OF STOCK OWNERSHIP.

                  (a) Promptly following each Purchase Date, the number of
shares of Common Stock purchased by each participant shall be deposited into an
account established in the participant's name at a stock brokerage or other
financial services firm designated or approved by the Committee (the "Plan
Financial Agent"). In the event a participant or former participant shall have
an account balance of less than one full share with the Plan Financial Agent as
of the first day of any Offering Period for which such participant has elected
not to participate in the Plan, the Plan Financial Agent shall cause such
fractional share to be sold as promptly as possible and the cash proceeds from
such sale to be paid to the account holder with no interest.

                  (b) Following termination of a participant's employment for
any reason, the participant shall have a period of 60 days to notify the Plan
Financial Agent whether such participant desires (i) to receive a certificate
representing all full shares then in the participant's account with the Plan
Financial Agent and cash in lieu of any fractional share interest or (ii) to
sell the shares, including any fractional share, in the participant's account
through the Plan


                                      -10-
<PAGE>   11
Financial Agent. If the terminated participant fails to file such notice with
the Plan Financial Agent within 60 days after termination, or within such other
time as established by the Committee, he or she shall be deemed to have elected
the alternative set forth in clause (i) above.

         13.      WITHDRAWAL.

                  (a) Each participant may withdraw from an Offering Period
under this Plan by signing and delivering to the person designated by the
Committee a written notice to that effect on a form provided for such purpose.
Such withdrawal may be elected at any time on or prior to the 15th day of the
last month (or if such date is not a business day, the immediately preceding
business day) of an Offering Period, unless a different time is set by the
Committee with respect to all eligible employees with respect to an Offering
Period.

                  (b) Upon withdrawal from this Plan, the accumulated payroll
deductions of the participant not theretofore utilized for the purchase of
shares of Common Stock on a Purchase Date shall be returned to the withdrawing
participant, without interest. In the event a participant voluntarily elects to
withdraw from this Plan, he or she may not resume his or her participation in
this Plan during the same Offering Period, but he or she may participate in any
subsequent Offering Period by filing a new authorization for payroll deductions
in the same manner as set forth above for initial participation in this Plan.

         14.      TERMINATION OF EMPLOYMENT; LEAVE OF ABSENCE.

                  Termination of a participant's employment for any reason,
including retirement, death, or the failure of a participant to remain an
eligible employee, immediately terminates his or her participation in this Plan.
In such event, except as provided in Section 15, the payroll deductions credited
to the participant's account will be returned to him or her or, in the case of
his or her death, to his or her beneficiary or heirs, without interest. For
purposes of this Section


                                      -11-
<PAGE>   12
14, an employee will not be deemed to have terminated employment or failed to
remain in the continuous employ of the Company in the case of any leave of
absence approved by the Company or Designated Subsidiary.

         15.      RETURN OF PAYROLL DEDUCTIONS.

                  In the event a participant's interest in this Plan is
terminated by withdrawal, termination of employment, or otherwise, or in the
event this Plan is terminated by the Board, the Company shall promptly deliver
to the participant all contributions of the participant to the Plan which have
not yet been applied to the purchase of stock unless such termination of
participation occurs later than the 15th day of the final month of the Offering
Period (or if such date is not a business day, on the preceding business day) or
such later date established by the Committee in a uniform and consistent manner,
in which event such contributions will be utilized to purchase Common Stock for
the participant. No interest shall accrue on the payroll deductions of a
participant in this Plan.

         16.      CHANGE OF OWNERSHIP AND CAPITAL CHANGES.

                  (a) If the Company is acquired, whether by merger,
consolidation, or sale of substantially all of its assets, all payroll
deductions for the period in which such acquisition occurs will automatically be
applied to the purchase of Company shares immediately prior to the effective
date of such acquisition.

                  (b) In the event that at any time or from time to time a stock
dividend, stock split, spin-off, combination or exchange of shares,
recapitalization, merger, consolidation, distribution to stockholders other than
a normal cash dividend, or other change in the Company's corporate or capital
structure results in (a) the outstanding shares of Common Stock or any
securities exchanged therefor or received in their place being exchanged for a
different number


                                      -12-
<PAGE>   13
or class of securities of the Company or of any other corporation or (b) new,
different, or additional securities of the Company or of any other corporation
being received by the holders of shares of Common Stock, then the Committee, in
its sole discretion, shall make such equitable adjustments as it shall deem
appropriate in the circumstances in the maximum number and kind of shares of
stock subject to this Plan as set forth in the Plan, the number and kind of
shares subject to purchase under outstanding Options, and the Purchase Price.
The determination by the Committee as to the terms of any of the foregoing
adjustments shall be conclusive and binding.

         17.      NONASSIGNABILITY.

                  Neither payroll deductions credited to a participant's account
nor any rights with regard to the exercise of an Option or to receive shares
under this Plan may be assigned, transferred, pledged, or otherwise disposed of
in any way (other than by will, the laws of descent and distribution, or as
provided in Section 24 hereof by the participant). Any such attempt at
assignment, transfer, pledge, or other disposition shall be void and without
effect.

         18.      REPORTS AND STATUS OF ACCOUNTS.

                  Individual accounts will be maintained by the Plan Financial
Agent for each participant in this Plan. The Participant shall have all
ownership rights with respect to shares of Common Stock held in his or her
account by the Plan Financial Agent, including the right to vote such shares and
to receive any dividends or distributions which may be declared thereon by the
Board. The Plan Financial Agent shall send to each participant promptly after
the end of each Offering Period a report of his or her account setting forth
with respect to such Offering Period the total payroll deductions accumulated,
the number of shares purchased, and the per share price thereof, and also
setting forth the total number of shares then held in his or her account.
Neither


                                      -13-
<PAGE>   14
the Company nor any Designated Subsidiary shall have any liability for any error
or discrepancy in any such report.

         19.      NO RIGHTS TO CONTINUED EMPLOYMENT; NO IMPLIED RIGHTS.

                  Neither this Plan nor the grant of any Option hereunder shall
confer any right on any employee to remain in the employ of the Company or any
Subsidiary or restrict the right of the Company or any Subsidiary to terminate
such employee's employment. The grant of any Option hereunder during any
Offering Period shall not give a participant any right to similar grants
thereafter.

         20.      EQUAL RIGHTS AND PRIVILEGES.

                  All eligible employees shall have equal rights and privileges
with respect to this Plan except as required by applicable law so that this Plan
qualifies as an "employee stock purchase plan" within the meaning of Section 423
or any successor provision of the Code and the related regulations. Any
provision of this Plan which is inconsistent with Section 423 or any successor
provision of the Code shall, without further act or amendment by the Company,
the Board, or the Committee, be reformed to comply with the requirements of
Section 423. This Section 20 shall take precedence over all other provisions in
this Plan.

         21.      NOTICES.

                  All notices or other communications by a participant to the
Company under or in connection with this Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

         22.      AMENDMENT OF PLAN.

                  The Board may amend this Plan in such respects as it shall
deem advisable; however, stockholder approval will be required for any amendment
that will increase the total number of shares as to which Options may be granted
under this Plan, or, but for such shareholder approval, cause this Plan to fail
to continue to qualify as an "employee stock purchase plan" under Section 423 of
the Code or cause the purchase of shares thereunder to fail to be exempt from
the provisions of Section 16(b) of the Exchange Act.

         23.      TERMINATION OF THE PLAN.

                  The Board may suspend or terminate this Plan at any time.
Unless this Plan shall theretofore have been terminated by the Board, this Plan
shall terminate on, and no Options shall be granted after, June 30, 2009. No
Options shall be granted during any period of suspension of this Plan.

         24.      DESIGNATION OF BENEFICIARY.

                  (a) A participant may file a written designation of a
beneficiary who is to receive any shares and cash, if any, from the
participant's account under this Plan in the event of such participant's death
prior to delivery to him or her (or to the Plan Financial Agent on his or her
behalf) of such shares and cash.

                  (b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under this
Plan who is living at the time of such participant's death, the Company shall
deliver such shares or cash to the executor or administrator of the estate of
the participant, or if no such executor or administrator has been appointed (to
the knowledge of the Company), the Company, in its discretion, may deliver such
shares or cash to the spouse or to any one or more dependents or relatives of
the participant or, if no spouse,


                                      -15-
<PAGE>   16
dependent, or relative is known to the Company, to such other person as the
Company may in good faith determine to be the appropriate designee.

         25.      CONDITIONS UPON ISSUANCE OF SHARES; LIMITATION ON SALE OF
                  SHARES.

                  Shares shall not be issued with respect to an Option unless
the exercise of such Option and the issuance and delivery of such shares
pursuant thereto shall comply with all applicable provisions of law, domestic or
foreign, including, without limitation, the Securities Act of 1933, as amended,
the Exchange Act, the rules and regulations promulgated thereunder, and the
requirements of any stock exchange or automated quotation system upon which the
shares may then be listed, and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

         26.      EFFECTIVE DATE.


                  This plan was initially adopted May 17, 1999, by the
shareholders of the Company, and is to be effective September 1, 1999.


         27.      GOVERNING LAW.

                  Except to the extent that provisions of this Plan are governed
by applicable provisions of the Code or any other substantive provision of
federal law, this Plan shall be construed in accordance with, and shall be
governed by, the substantive laws of the State of Arizona without regard to any
provisions of Arizona law relating to the conflict of laws.

                  South River Drive, Tempe, Arizona 85281.

         B.       The Lease is in full force and effect, and neither Lessee nor
                  Lessor has actual knowledge of any default or breach by the
                  other under the Lease.

         C.       Lessor and Lessee desire to amend the Lease as provided in
                  this Amendment.

                  sales taxes, subject to change, and other sums which may be

payable monthly or quarterly, as Lessor shall designate, during each 12-month
period of the Lease term, on the same day as the Base Rent is due hereunder.

Deposit bears to the initial Base Rent set forth in Paragraph 1.5. Lessor shall
not be required to keep all or any part of the Security Deposit separate from
its general accounts. Lessor shall, at the expiration or earlier termination of
the term hereof and after Lessee has vacated the Premises, return to Lessee (or,
at Lessor's option, to the last assignee, if any, of Lessee's interest herein),

its use, or to be prepayment for any monies to be paid by Lessee under this
Lease.

Lessor and in compliance with all Applicable Requirements, use any ordinary and
customary materials reasonably required to be used by Lessee in the normal
course of the Permitted Use, so long as such use is not a Reportable Use and

in, on, under or about the Premises or the Building, other than as previously
consented to by Lessor, Lessee shall immediately give Lessor written notice
thereof, together with a copy of any statement, report, notice, registration,
application, permit, business plan, license, claim, action, or proceeding given

which would otherwise afford Lessee the right to make repairs at Lessor's

Building, Industrial Center or Common Areas in good order, condition and repair.

are not visible from the outside of the Premises, do not involve puncturing,
relocating or removing the roof or any existing walls, or changing or
interfering with the fire sprinkler or fire detection systems and the cumulative
cost thereof during the term of this Lease as extended does not exceed

                  (b)      CONSENT. Any Alternations or Utility Installations
that Lessee shall desire to make and which require the consent of the Lessor
shall be presented to Lessor in written form with detailed plans. All consents

such permits together with a copy of the plans and specifications for the
Alteration or Utility Installation to Lessor prior to commencement of the work
thereon; and (iii) the compliance by Lessee with all conditions of said permits

consent to any requested Alteration or Utility Installation that costs $2,500,00

commencement of any work in, on, or about the Premises, and Lessor shall have
the right to post notices of non-responsibility in or on the Premises as
provided by law. It Lessee shall, in good faith, contest the validity of any
such lien, claim or demand, then Lessee shall, at its sole expense, defend and
protect itself, Lessor and the Premises against the same and shall pay and
satisfy any such adverse judgment that may be rendered thereon before the
enforcement thereof against the Lessor or the Premises. If Lessor shall require,
Lessee shall furnish to Lessor a surety bond satisfactory to Lessor in an amount
equal to one and one-half times the amount of such contested lien claim or
demand, indemnifying Lessor against liability for the same, as, required by law
for the holding of the Premises free from the effect of such lien or claim. In
addition, Lessor may require Lessee to pay Lessor's attorneys' fees and costs in
participating in such action if Lessor shall decide it is to Its best interest
to do so.

         7.4      OWNERSHIP, REMOVAL, SURRENDER, AND RESTORATION.

                  (a)      OWNERSHIP. Subject to Lessor's right to require their
removal and to cause Lessee to become the owner thereof as hereinafter provided
in this Paragraph 7.4, all Alterations and Utility Installations made to the
Premises by Lessee shall be the property of and owned by Lessee, but considered
a part of the Premises. Lessor may, at any time and at its option, elect in

that their installation may have been consented to by Lessor. Lessor may require
the removal at any time of all or any part of any Alterations or Utility
Installations made without the required consent of Lessor.

                  (c)      SURRENDER/RESTORATION. Lessee shall surrender the
Premises by the end of the last day of the Lease term or any earlier termination
date, clean and free of debris and in good operating order, condition and state
of repair, ordinary wear and tear excepted, Ordinary wear and tear shall not
include any damage or deterioration that would have been prevented by good
maintenance practice or by Lessee performing all of its obligations under this
Lease. Except as otherwise agreed or specified herein, the Premises, as

8.       INSURANCE; INDEMNITY.

         8.1      PAYMENT OF PREMIUM INCREASES.

                  (a)      As used herein, the term "INSURANCE COST INCREASE" is
defined as any increase in the actual cost of the insurance applicable to the
Building and required to be carried by Lessor pursuant to Paragraphs 8.2(b),
8.3(a) and 8.3(b), ("REQUIRED INSURANCE"), over and above the Base Premium, as
hereinafter defined, calculated on an annual basis. "Insurance Cost Increase"
shall include, but not be limited to, requirements of the holder of a mortgage
or deed of trust covering the Premises, increased valuation of the Premises,
and/or a general premium rate increase. The term "Insurance Cost Increase" shall
not, however, include any premium increases resulting from the nature of the
occupancy of any other lessee of the Building. If the parties insert a dollar
amount in Paragraph 1.9, such amount shall be considered the "BASS PREMIUM." If
a dollar amount has not been inserted in Paragraph 1.9, the "Base Premium" shall
be the annual premium applicable in the calendar year during which the lease
commences. If the Building was not fully occupied during such twelve (12) month
period, the "Base Premium" shall be the lowest annual premium reasonably
obtainable for the Required Insurance as of the Commencement Date, assuming the
most nominal use possible of the Building. In no event, however, shall Lessee be
responsible for any portion of the premium cost attributable to liability
insurance coverage in excess of $1,000,000 procured under Paragraph 8.2(b).

                  (b)      Lessee shall pay any Insurance Cost Increase to
Lessor pursuant to Paragraph 4.2. Premiums for policy periods commencing prior
to, or extending beyond, the term of this Lease shall be prorated to coincide
with the corresponding Commencement Date or Expiration Date.

8.2      LIABILITY INSURANCE.

         (a)      CARRIED BY LESSEE. Lessee shall obtain and keep in force
during the term of this Lease a Commercial General Liability policy of insurance
protecting Lessee, Lessor and any Lender(s) whose names have been provided to
Lessee in writing (as additional insureds) against claims for bodily injury,
personal injury and property damage based upon, involving or arising out of the
ownership, use, occupancy or maintenance of the Premises and all areas
appurtenant thereto. Such insurance shall be on an occurrence basis providing
single limit coverage in an amount not less than $1,000,000 per occurrence with
an "Additional Insured-Managers or Lessors of Premises" endorsement and contain
the "Amendment of the Pollution Exclusion" endorsement for damage caused by
heat, smoke or fumes from a hostile fire. The policy shall not contain any
intra-insured exclusions as between insured persons or organizations, but shall
include coverage for liability assumed under this Lease as an "Insured contract"
for the performance of Lessee's indemnity obligations under this Lease. The
limits of said insurance required by this Lease or as carried by Lessee shall
not, however, limit the liability of Lessee nor relieve Lessee of any obligation
hereunder. All insurance to be carried by Lessee shall not, however, limit the
liability of Lessee nor relieve Lessee of any obligation hereunder. All
insurance to be carried by Lessee shall be primary to and not contributory with
any similar insurance carried by Lessor, whose insurance shall be considered
excess insurance only.

         (b)      CARRIED BY LESSOR. Lessor shall also maintain liability
insurance described in Paragraph 8.2(a) above, in addition to and not in lieu
of, the insurance required to be maintained by Lessee. Lessee shall not be named
as an additional insured therein.

         8.3      PROPERTY INSURANCE-BUILDING, IMPROVEMENTS AND RENTAL VALUE.

                  (a)      BUILDING AND IMPROVEMENTS. Lessor shall obtain and
keep in force during the term of this Lease a policy or policies in the name of
Lessor, with loss payable to Lessor and to any Lender(s), insuring against loss
or damage to the Premises. Such insurance shall be for full replacement cost, as
the same shall exist

                                                                Initial_________
                                                                       _________

from time to time, or the amount required by any Lender(s), but in no event more
than the commercially reasonable and available insurable value thereof if, by
reason of the unique nature or a age of the improvements involved, such latter
amount is less than full replacement cost. Lessee-Owned Alterations and Utility
Installations, Trade Fixtures and Lessee's personal property shall be insured by
Lessee pursuant to Paragraph 8.4. If the coverage is available and commercially
appropriate, Lessor's policy or policies shall insure against all risks of
direct physical loss or damage (except the perils of flood and/or earthquake
unless required by a Lender or included in the Base Premium), including coverage
for any additional costs resulting from debris removal and reasonable amounts of
coverage for the, enforcement of any ordinance or law regulating the
reconstruction or replacement of any undamaged sections of the Building required
to be demolished or removed by reason of the enforcement of any building,
zoning, safety or land use laws as the result of a covered loss, but not
including plate glass insurance. Said policy or policies shall also contain an
agreed valuation provision in lieu of any co-insurance clause, waiver of
subrogation, and inflation guard protection causing an Increase In the annual
property insurance coverage amount by a factor of not less than the adjusted
U.S. Department of Labor Consumer Price Index for All Urban Consumers for the
city nearest to where the Premises are located.

                  (b)      RENTAL VALUE. Lessor shall also obtain and keep in
force during the term of this Lease a policy or policies in the name of Lessor,
with loss payable to Lessor and any Lender(s), insuring the loss of the full
rental and other charges payable by all lessees of the Building to Lessor for
one year (including all Real Property Taxes, Insurance costs, all Common Area
Operating Expenses and any scheduled rental increases). Said insurance may
provide that in the event the Lease is terminated by reason of an insured loss,
the period of indemnity for such coverage shall be extended beyond the date of
the completion of repairs or replacement of the Premises, to provide for one
full year's loss of rental revenues from the date of any such loss. Said
insurance shall contain an agreed valuation provision in lieu of any
co-insurance clause, and the amount of coverage shall be adjusted annually to
reflect the projected rental income, Real Property Taxes, insurance premium
costs and other expenses, if any, otherwise payable, for the next 12-month
period. Common Area Operating Expenses shall include any deductible amount in
the event of such loss.

                  (c)      ADJACENT PREMISES. Lessee shall pay for any increase
in the premiums for the property insurance of the Building and for the Common
Areas or other buildings in the Industrial Center if said increase is caused by
lessee's acts, omissions, use or occupancy of the Premises.

                  (d)      LESSEE'S IMPROVEMENTS. Since Lessor is the Insuring
Party, Lessor shall not be required to insure Lessee-Owned Alterations and
Utility Installations unless the item in question has become the property of
Lessor under the terms of this Lease.

         8.4      LESSEE'S PROPERTY INSURANCE. Subject to the requirements of
Paragraph 8.5, Lessee at its cost shall either by separate policy or, at
Lessor's option, by endorsement to a policy already carried, maintain insurance
coverage on all of Lessee's personal property, Trade Fixtures and Lessee-Owned
Alterations and Utility Installations in, on, or about the Premises similar in
coverage to that carried by Lessor as the Insuring Party under Paragraph 8.3(a).
Such insurance shall be full replacement cost coverage with a deductible not to
exceed $1,000 per occurrence. The proceeds from any such insurance shall be used
by Lessee for the replacement of personal property and the restoration of Trade
Fixtures and Lessee-Owned Alterations and Utility Installations. Upon request
from Lessor, Lessee shall provide Lessor with written evidence that such
insurance is in force.

         8.5      INSURANCE POLICIES. Insurance required hereunder shall be in
companies duly licensed to transact business in the state where the Premises are
located, and maintaining during the policy term a "General Policyholders Rating"
of at least B+, V, or such other rating as may be required by a Lender, as set
forth In the most current Issue of "Bests Insurance Guide." Lessee shall not do
or permit to be done anything which shall invalidate the insurance policies
referred to in this Paragraph 8. Lessee shall cause to be delivered to Lessor,
within seven (7)

                                                                Initial_________

days after the earlier of the Early Possession Date or the Commencement Date,
certified copies of, or certificates evidencing the existence and amounts of,
the insurance required under Paragraph 8.2(a) and 8.4. No such policy shall be
cancelable or subject to modification except after thirty (30) days' prior
written notice to Lessor. Lessee shall at least thirty (30) days prior to the
expiration of such policies, furnish Lessor with evidence of renewals or
"insurance binders" evidencing renewal thereof, or Lessor may order such
insurance and charge the cost thereof to Lessee, which amount shall be payable
by Lessee to Lessor upon demand.

         8.6      WAIVER OF SUBROGATION. Without affecting any other rights or
remedies, Lessee and Lessor each hereby release and relieve the other, and waive
their entire right to recover damages (whether in contract or in tort) against
the other, for loss or damage to their property arising out of or incident to
the perils required to be insured against under Paragraph 8. The effect of such
releases and waivers of the right to recover damages shall not be limited by the
amount of insurance carried or required, or by any deductibles applicable
thereto. Lessor and Lessee agree to have their respective insurance companies
issuing property damage insurance waive any right to subrogation that such
companies may have against Lessor or Lessee, as the case may be, so long as the
insurance is not invalidated thereby.

         8.7      INDEMNITY. Except for Lessor's negligence and/or breach of
express warranties, Lessee shall indemnify, protect, defend and hold harmless
the Premises, Lessor and its agents, Lessor's master or ground lessor, partners
and Lenders, from and against any and all claims, loss of rents and/or damages,
costs, liens, judgments, penalties, loss of permits, attorneys' and consultants'
fees, expenses and/or liabilities arising out of, involving, or in connection
with, the occupancy of the Premises by Lessee, the conduct of Lessee's business,
any act, omission or neglect of Lessee, its agents, contractors, employees or
invitees, and out of any Default or Breach by Lessee in the performance in a
timely manner of any obligation on Lessee's part to be performed under this
Lease. The foregoing shall include, but not be limited to, the defense or
pursuit of any claim or any action or proceeding involved therein, and whether
or not (in the case of claims made against Lessor) litigated and/or reduced to
judgment. In case any action or proceeding be brought against Lessor by reason
of any of the foregoing matters, Lessee upon notice from Lessor shall defend the
same at Lessee's expense by counsel reasonably satisfactory to Lessor and Lessor
shall cooperate with Lessee in such defense. Lessor need not have first paid any
such claim in order to be so indemnified.

         8.8      EXEMPTION OF LESSOR FROM LIABILITY. Lessor shall not be liable
for injury or damage to the person or goods, wares, merchandise or other
property of Lessee, Lessee's employees, contractors, invitees, customers, or any
other person in or about the Premises, whether such damage or injury is caused
by or results from fire, steam, electricity, gas, water or rain, or from the
breakage, leakage, obstruction or other defects of pipes, fire sprinklers,
wires, appliances, plumbing, air conditioning or lighting fixtures, or from any
other cause, whether said injury or damage results from conditions arising upon
the Promises or upon other portions of the Building of which the Premises are a
part, from other sources or places, and regardless of whether the cause of such
damage or injury or the means of repairing the same is accessible or not. Lessor
shall not be liable for any damages arising from any act or neglect of any other
lessee of Lessor nor from the failure by Lessor to enforce the provisions of any
other lease in the Industrial Center. Notwithstanding Lessor's negligence or
breach of this Lease, Lessor shall under no circumstances be liable for injury
to Lessee's business or for any loss of income or profit therefrom.

9.       DAMAGE OR DESTRUCTION.

         9.1      DEFINITIONS.

                  (a)      "PREMISES PARTIAL DAMAGE" shall mean damage or
destruction to the Premises, other than Lessee-Owned Alterations and Utility
Installations, the repair cost of which damage or destruction is less than fifty
percent (50%) of the then Replacement Cost (as defined in paragraph 9.1(d) of
the Premises (excluding Lessee-Owned Alterations and Utility Installations and
Trade Fixtures) immediately prior to such damage or destruction.

                                                                Initial_________
                                                                       _________

<PAGE>   16
                  (b)      "PREMISES TOTAL DESTRUCTION" shall mean damage or
destruction to the Premises, other than Lessee-Owned Alterations and Utility
Installations, the repair cost of which damage or destruction is fifty percent
(50%) or more of the then Replacement Cost of the Premises (excluding
Lessee-Owned Alterations and Utility Installations and Trade Fixtures)
immediately prior to such damage or destruction. In addition, damage or
destruction to the Building, other than Lessee Owned Alterations and Utility
Installations and Trade Fixtures of any lessees of the Building, the cost of
which damage or destruction is fifty percent (50%) or more of the then
Replacement Cost (excluding Lessee-Owned Alterations and Utility Installations
and Trade Fixtures of any lessees of the Building) of the Building shall, at the
option of Lessor, be deemed to be Premises Total Destruction.

                  (c)      "INSURED LOSS" shall mean damage or destruction to
the Premises, other than Lessee-Owned Alterations and Utility Installations and
Trade Fixtures, which was caused by an event required to be covered by the
insurance described in Paragraph 8.3(a) irrespective of any deductible amounts
or coverage limits involved.

                  (d)      "REPLACEMENT COST" shall mean the cost to repair or
rebuild the improvements owned by Lessor at the time of the occurrence to their
condition existing immediately prior thereto, including demolition, debris
removal and upgrading required by the operation of applicable building codes,
ordinances or laws, and without deduction for depreciation.

                  (e)      "HAZARDOUS SUBSTANCE CONDITION" shall mean the
occurrence or discovery of a condition involving the presence of, or a
contamination by, a Hazardous Substance as defined in Paragraph 6.2(a), in, on,
or under the Premises.

         9.2      PROMISES PARTIAL DAMAGE-INSURED LOSS. If Premises Partial
Damage that is an Insured Loss occurs, then Lessor shall, at Lessor's expense,
repair such damage (but not Lessees Trade Fixtures or Lessee-Owned Alterations
and Utility Installations) as soon as reasonably possible and this Lease shall
continue in full force and effect. In the event, however, that there is a
shortage of insurance proceeds and such shortage is due to the fact that, by
reason of the unique nature of the improvements in the Premises, full
replacement cost insurance coverage was not commercially reasonable and
available, Lessor shall have no obligation to pay for the shortage in insurance
proceeds or to fully restore the unique aspects of the Premises unless Lessee
provides Lessor with the funds to cover same, or adequate assurance thereof,
within ten (10) days following receipt of written notice of such shortage and
request therefor. If Lessor receives said funds or adequate assurance thereof
within said ten (10) day period, Lessor shall complete them as soon as
reasonably possible and this Lease shall remain in full force and effect. If
Lessor does not receive such funds or assurance within said period, Lessor may
nevertheless elect by written notice to Lessee within ten (10) days thereafter
to make such restoration and repair as is commercially reasonable with Lessor
paying any shortage in proceeds, in which case this Lease shall remain in full
force and effect. If Lessor does not receive such funds or assurance within such
ten (10) day period, and if Lessor does not so elect to restore and repair, then
this Lease shall terminate sixty (60) days following the occurrence of the
damage or destruction. Unless otherwise agreed, Losses shall in no event have
any right to reimbursement from Lessor for any funds contributed by Lessee to
repair any such damage or destruction. Premises Partial Damage due to flood or
earthquake shall be subject to Paragraph 9.3 rather than Paragraph 9.2,
notwithstanding that there may be some insurance coverage, but the net proceeds
of any such insurance shall be made available for the repairs if made by either
Party.

         9.3      PARTIAL DAMAGE-UNINSURED LOSS. If Premises Partial Damage that
is not an Insured Loss occurs, unless caused by a negligent or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense and
this Lease shall continue in full force and effect), Lessor may at Lessors
option, either (i) repair such damage as soon as reasonably possible at Lessor's
expense, in which event this Lease shall continue in full force and effect, or
(ii) give written notice to Lessee within thirty (30) days after receipt by
Lessor of knowledge of the

occurrence of such damage of Lessee's desire to terminate this Lease as of the
date sixty (60) days following the date of such notice. In the event Lessor
elects to give such notice of Lessor's intention to terminate this Lease, Lessee
shall have the right within ten (10) days after the receipt of such notice to
give written notice to Lessor of Lessee's commitment to pay for the repair of
such damage totally at Lessee's expense and without reimbursement from Lessor.
Lessee shall provide Lessor with the required funds or satisfactory assurance
thereof within thirty (30) days following such commitment from Lessee. In such
event this Lease shall continue in full force and effect, and Lessor shall
proceed to make such repairs as soon as reasonably possible after the required
funds are available. If Lessee does not give such notice and provide the funds
or assurance thereof within the times specified above, this Lease shall
terminate as of the date specified in Lessor's notice of termination.

         9.4      TOTAL DESTRUCTION. Notwithstanding any other provision hereof,
if Premises Total Destruction occurs (including any destruction required by any
authorized public authority), this Lease shall terminate sixty (60) days
following the date of such premises Total Destruction, whether or not the damage
or destruction is an Insured Loss or was caused by a negligent or willful act of
Lessee. In the event, however, that the damage or destruction was caused by
Lessee, Lessor shall have the right to recover Lessor's damages from Lessee
except as released and waived in Paragraph 9.7.

         9.5      DAMAGE NEAR END OF TERM. If at any time during the last six
(6) months of the term of this Lease there is damage for which the cost to
repair exceeds one month's Base Rent, whether or not an Insured Loss, Lessor
may, at Lessor's option, terminate this Lease effective sixty (60) days
following the date of occurrence of such damage by giving written notice to
Lessee of Lessor's election to do so within thirty (30) days after the date of
occurrence of such damage. Provided, however, if Lessee at that time has an
exercisable option to extend this Lease or to purchase the Premises, then Lessee
may preserve this Lease by (a) exercising such option, and (b) providing Lessor
with any shortage in insurance proceeds (or adequate assurance thereof) needed
to make the repairs on or before the earlier of (i) the date which is ten (10)
days after Lessee's receipt of Lessor's written notice purporting to terminate
this Lease, or (ii) the day prior to the date upon which such option expires. If
Lessee duly exercises such option during such period and provides Lessor with
funds (or adequate assurance thereof) to cover any shortage in insurance
proceeds, Lessor shall, at Lessor's expense repair such damage as soon as
reasonably possible and this Lease shall continue in full force and effect. If
Lessee falls to exercise such option and provide such funds or assurance during
such period, then this Lease shall terminate as of the date set forth in the
first sentence of this Paragraph 9.5.

         9.6      ABATEMENT OF RENT; LESSEE'S REMEDIES.

                  (a)      In the event of (i) Premises Partial Damage or (ii)
Hazardous Substance Condition for which Lessee is not legally responsible, the
Base Rent, Common Area Operating Expenses and other charges, if any, payable by
Lessee hereunder for the period during which such damage or condition, its
repair, remediation or restoration continues, shall be abated in proportion to
the degree to which Lessee's use of the Premises is impaired, but not in excess
of proceeds from insurance required to be carried under Paragraph 8.3(b). Except
for abatement of Base Rent, Common Area Operating Expenses and other charges, if
any, as aforesaid, all other obligations of Lessee hereunder shall be performed
by Lessee, and Lessee shall have no claim against Lessor for any damage suffered
by reason of any such damage, destruction, repair, remediation or restoration.

                  (b)      If Lessor shall be obligated to repair or restore the
Premises under the provisions of this Paragraph 9 and shall not commence, in a
substantial and meaningful way, the repair or restoration of the Premises within
ninety (90) days after such obligation shall accrue, Lessee may, at any time
prior to the commencement of such repair or restoration, give written notice to
Lessor and to any Lenders of which Lessee has actual notice of Lessee's election
to terminate this Lease on a date not less than sixty (60) days following the
giving of such notice. It Lessee gives such notice to Lessor and such Lenders
and such repair or restoration is not commenced within thirty

(30) days after receipt of such notice, this Lease shall terminate as of the
date specified in said notice. If Lessor or a Lender commences the repair or
restoration of the Premises within thirty (30) days after the receipt of such
notice, this Lease shall continue in full force and effect. "COMMENCE" as used
in this Paragraph 9.6 shall mean either the unconditional authorization of the
preparation of the required plans or the beginning of the actual work on the
Premises, whichever occurs first.

         9.7      HAZARDOUS SUBSTANCE CONDITIONS. If a Hazardous Substance
Condition occurs, unless Lessee is legally responsible therefor (in which case
Lessee shall make the investigation and remediation thereof required by
Applicable Requirements and this Lease shall continue in full force and effect,
but subvert to Lessor's rights under Paragraph 6.2(c) and Paragraph 13), Lessor
may at Lessor's option either (i) investigate and remediate such Hazardous
Substance Condition, if required, as soon as reasonably possible at Lessor's
expense, in which event this Lease shall continue in full force and effect, or
(ii) if the estimated cost to investigate and remediate such condition exceeds
twelve (12) times the then monthly Base Rent, or $100,000 whichever is greater,
give written notice to Lessee within thirty (30) days after receipt by Lessor of
knowledge of the occurrence of such Hazardous Substance Condition of Lessor's
desire to terminate this Lease as of the date sixty (60) days following the date
of such notice. In the event Lessor elects to give such notice of Lessor's
intention to terminate this Lease, Lessee shall have the right within ten (10)
days after the receipt of such notice to give written notice to Lessor of
Lessee's commitment to pay for the excess costs of (a) investigation and
remediation of such Hazardous Substance Condition to the extent required by
Applicable Requirements, over (b) an amount equal to twelve (12) times the then
monthly Base Rent or $100,000, whichever is greater. Lessee shall provide Lessor
with the funds required of Lessee or satisfactory assurance thereof within
thirty (30) days following said commitment by Lessee. In such event this Lease
shall continue in full force and effect, and Lessor shall proceed to make such
investigation and remediation as soon as reasonably possible after the required
funds are available. If Lessee does not give such notice and provide the
required funds or assurance thereof within the time period specified above, this
Lease shall terminate as of the date specified in Lessor's notice of
termination.

         9.8      TERMINATION-ADVANCE PAYMENTS. Upon termination of this Lease
pursuant to this Paragraph 9, Lessor shall return to Lessee any advance payment
made by Lessee to Lessor and so much of Lessee's Security Deposit as has not
been, or is not then required to be, used by Lessor under the terms of this
Lease.

         9.9      WAIVER OF STATUTES. Lessor and Lessee agree that the terms of
this Lease shall govern the effect of any damage to or destruction of the
Premises and the Building with respect to the termination of this Lease and
hereby waive the provisions of any present or future statute to the extent it is
inconsistent herewith.

10.      REAL PROPERTY TAXES.

         10.1     PAYMENT OF TAXES. Lessor shall pay the Real Property Taxes, as
defined in Paragraph 10.2(a), applicable to the Industrial Center, and except as
otherwise provided in Paragraph 10.3, any increases in such amounts over the
Base Real Property Taxes shall be included in the calculation of Common Area
Operating Expenses in accordance with the provisions of Paragraph 4.2.

         10.2     REAL PROPERTY TAX DEFINITIONS.

                  (a)      As used herein, the term "REAL PROPERTY TAXES" shall
include any form of real estate tax or assessment, general, special, ordinary or
extraordinary, and any license fee, commercial rental tax, improvement bond or
bonds, levy or tax (other than inheritance, personal income or estate taxes)
imposed upon the Industrial Center by any authority having the direct or
indirect power to tax, including any city, state or federal government, or any
school, agricultural, sanitary, fire, street, drainage, or other improvement
district thereof, levied against any legal or equitable interest of Lessor in
the Industrial Center or any portion thereof, Lessor's right to rent or other


                                                                Initial_________
                                                                       _________

income therefrom, and/or Lessor's business of leasing the Premises. The term
"REAL PROPERTY TAXES" shall also include any tax, fee, levy, assessment or
charge, or any increase therein, imposed by reason of events occurring, or
changes in Applicable Law taking effect, during the term of this Lease,
including but not limited to a change in the ownership of the Industrial Center
or in the improvements thereon, the execution of this Lease, or any
modification, amendment or transfer thereof, and whether or not contemplated by
the Parties.

                  (b)      As used herein, the term "BASE REAL PROPERTY TAXES"
shall be the amount of Real Property Taxes, which are assessed against the
Premises, Buildings or Common Areas in the Industrial Center in the calendar
year during which the Lease commences. In calculating Real Property Taxes for
any calendar year, the Real Property Taxes for any real estate tax year shall be
included in the calculation of Real Property Taxes for such calendar year based
upon the number of days which such calendar year and tax year have in common.

         10.3     ADDITIONAL IMPROVEMENTS. Common Area Operating Expenses shall
not include Real property Taxes specified in the tax assessor's records and work
sheets as being caused by additional improvements placed upon the industrial
Center by other lessees or by Lessor for the exclusive enjoyment of such other
lessees. Notwithstanding Paragraph 10.1 hereof, Lessee shall, however, pay to
Lessor at the time Common Area Operating Expenses are payable under Paragraph
4.2, the entirety of any increase in Real Property Taxes if assessed solely by
reason of Alterations, Trade Fixtures or Utility Installations placed upon the
Premises by Lessee or at Lessee's request.

         10.4     JOINT ASSESSMENT. If the Building is not separately assessed,
Real Property Taxes allocated to the Building shall be an equitable proportion
of the Real Property Taxes for all of the land and improvements included within
the tax parcel assessed, such proportion to be determined by Lessor from the
respective valuations assigned in the assessor's work sheets or such other
information as may be reasonably available. Lessor's reasonable determination
thereof, in good faith, shall be conclusive.

         10.5     LESSEE'S PROPERTY TAXES. Lessee shall pay prior to delinquency
all taxes assessed against and levied upon Lessee-Owned Alterations and Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee contained in the Premises or stored within the Industrial Center. When
possible, Lessee shall cause its Lessee-Owned Alterations and Utility
Installations, Trade Fixtures, furnishings, equipment and all other personal
property to be assessed and billed separately from the real property of Lessor.
If any of Lessee's said property shall be assessed with Lessor's real property,
Lessee shall pay Lessor the taxes attributable to Lessee's property within ten
(10) days after receipt of a written statement setting forth the taxes
applicable to Lessee's property.

11.      UTILITIES. Lessee shall pay directly for all utilities and services
supplied to the Premises, including but not limited to electricity, telephone,
security, gas and cleaning of the Premises, together with any taxes thereon. If
any such utilities or services are not separately metered to the Premises or
separately billed to the Premises, Lessee shall pay to Lessor a reasonable
proportion to be determined by Lessor of all such charges jointly metered or
billed with other premises in the Building, in the manner and within the time
periods set forth in Paragraph 4.2(d).

12.      ASSIGNMENT AND SUBLETTING.

         12.1     LESSOR'S CONSENT REQUIRED.

                  (a)      Lessee shall not voluntarily or by operation of law
assign, transfer, mortgage or otherwise transfer or encumber (collectively,
"assign") or sublet all or any part of Lessee's interest in this Lease or in the
Premises without Lessor's prior written consent given under and subject to the
terms of Paragraph 36.

                                                                Initial_________

<PAGE>   20
                  (b)      A change in the control of Lessee shall constitute an
assignment requiring Lessor's consent. The transfer, on a cumulative basis, of
twenty-five percent (25%) or more of the voting control of Lessee shall
constitute a change in control for this purpose.

                  (c)      The involvement of Lessee or its assets in any
transaction, or series of transactions (by way of merger, sale, acquisition,
financing, refinancing, transfer, leveraged buy-out or otherwise), whether or
not a formal assignment or hypothecation of this Lease or Lessee's assets
occurs, which results or will result in a reduction of the Net Worth of Lessee,
as hereinafter defined, by an amount equal to or greater than twenty-five
percent (25%) of such Net Worth of Lessee as it was represented to Lessor at the
time of full execution and delivery of this Lease or at the time of the most
recent assignment to which Lessor has consented, or as it exists immediately
prior to said transaction or transactions constituting such reduction, at
whichever time said Net Worth of Lessee was or is greater, shall be considered
an assignment of this Lease by Lessee to which Lessor may reasonably withhold
its consent. "NET WORTH OF LESSEE" for purposes of this Lease shall be the net
worth of Lessee (excluding any Guarantors) established under generally accepted
accounting principles consistently applied.

                  (d)      An assignment or subletting of Lessee's interest in
this Lease without Lessor's specific prior written consent shall, at Lessor's
option, be a De-fault curable after notice per Paragraph 13.1, or a non-curable
Breach without the necessity of any notice and grace period. If Lessor elects to
treat such unconsented to assignment or subletting as a non-curable Breach,
Lessor shall have the right to either: (i) terminate this Lease, or (ii) upon
thirty (30) days' written notice ("LESSOR'S NOTICE"), increase the monthly Base
Rent for the Premises to the greater of the then fair market rental value of the
Premises, as Reasonably determined by Lessor, or one hundred ten percent (110%)
of the Base Rent then in effect. Pending determination of the new fair market
rental value, if disputed by Lessee, Lessee shall pay the amount set forth in
Lessor's Notice, with any overpayment credited against the next installment(s)
of Base Rent coming due, and any underpayment for the period retroactively to
the effective date of the adjustment being due and payable immediately upon the
determination thereof. Further, in the event of such Breach and rental
adjustment, (i) the purchase price of any option to purchase the Premises held
by Lessee shall be subject to similar adjustment to the then fair market value
as reasonably determined by Lessor (without the Lease being considered an
encumbrance or any deduction for depreciation or obsolescence, and considering
the Premises at its highest and best use and in good condition) or one hundred
ten percent (110%) of the price previously in effect, (ii) any index-oriented
rental or price adjustment formulas contained in this Lease shall be adjusted to
require that the base index be determined with reference to the index applicable
to the time of such adjustment, and (iii) any fixed rental adjustments scheduled
during the remainder of the Lease terms shall be increased in the same ratio as
the new rental bears to the Base Rent in effect immediately prior to the
adjustment specified in Lessors Notice.

                  (e)      Lessee's remedy for any breach of this Paragraph 12.1
by Lessor shall be limited to compensatory damages and/or injunctive relief.

         12.2     TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

                  (a)      Regardless of Lessor's consent, any assignment or
subletting shall not (i) be effective without the express written assumption by
such assignee or sublessee of the obligations of Lessee under this Lease, (ii)
release Lessee of any obligations hereunder, nor (iii) alter the primary
liability of Lessee for the payment of Base Rent and other sums due Lessor
hereunder or for the performance of any other obligations to be performed by
Lessee under this Lease.

                  (b)      Lessor may accept any rent or performance of Lessee's
obligations from any person other than Lessee pending approval or disapproval of
an assignment. Neither a delay in the approval or disapproval of such assignment
nor the acceptance of any rent for performance shall constitute a waiver or
estoppel of Lessor's

                                                                Initial_________

right to exercise its remedies for the Default or Breach by Lessee of any of the
terms, covenants or conditions of this Lease.

                  (c)      The consent of Lessor to any assignment or subletting
shall not constitute a consent to any subsequent assignment or subletting by
Lessee or to any subsequent or successive assignment or subletting by the
assignee or sublessee. However, Lessor may consent to subsequent sublettings and
assignments or the sublease or any amendments or modifications thereto without
notifying Lessee or anyone else liable under this Lease or the sublease and
without obtaining their consent, and such action shall not relieve such persons
from liability under this Lease or the sublease.

                  (d)      In the event of any Default or Breach of Lessee's
obligation under this Lease, Lessor may proceed directly against Lessee, any
Guarantors or anyone else responsible for the performance of the Lessee's
obligations under this Lease, including any sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible therefor to
Lessor, or any security held by Lessor.

                  (e)      Each request for consent to an assignment or
subletting shall be in writing, accompanied by information relevant to Lessor's
determination as to the financial and operational responsibility and
appropriateness of the proposed assignee or sublessee, including but not limited
to the intended use and/or required modification of the Premises, if any,
together with a non-refundable deposit of $1,000 or ten percent (10%) of the
monthly Base Rent applicable to the portion of the Premises which is the subject
of the proposed assignment or sublease, whichever is greater, as reasonable
consideration for Lessor's considering and processing the request for consent.
Lessee agrees to provide Lessor with such other or additional information and/or
documentation as may be reasonably requested by Lessor.

                  (f)      Any assignee of, or sublessee under, this Lease
shall, by reason of accepting such assignment or entering into such sublease, be
deemed, for the benefit of Lessor, to have assumed and agreed to conform and
comply with each and every term, covenant, condition and obligation herein to be
observed or performed by Lessee during the term of said assignment or sublease,
other than such obligations as are contrary to or inconsistent with provisions
of an assignment or sublease to which Lessor has specifically consented in
writing.

                  (g)      The occurrence of a transaction described in
Paragraph 12.2(c) shall give Lessor the right (but not the obligation) to
require that the Security Deposit be increased by an amount equal to six (6)
times the then monthly Base Rent, and Lessor may make the actual receipt by
Lessor of the Security Deposit increase a condition to Lessor's consent to such
transaction.

                  (h)      Lessor, as a condition to giving its consent to any
assignment or subletting, may require that the amount and adjustment schedule of
the rent payable under this Lease be adjusted to what is then the market value
and/or adjustment schedule for property similar to the Premises as then
constituted, as determined by Lessor.

         12.3     ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. The
following terms and conditions shall apply to any subletting by Lessee of all or
any part of the Promises and shall be deemed included in all subleases under
this Lease whether or not expressly incorporated therein:

                  (a)      Lessee hereby assigns and transfers to Lessor all of
Lessee's interest in all rentals and income arising from any sublease of all or
a portion of the Premises heretofore or hereafter made by Lessee, and Lessor may
collect such rent and income and apply same toward Lessee's obligations under
this Lease; provided, however, that until a Breach (as defined in Paragraph
13.1) shall occur in the performance of Lessee's obligations under this Lease,
Lessee may, except as otherwise provided in this Lease, receive, collect and
enjoy the rents accruing under such sublease. Lessor shall not, by reason of the
foregoing provision or any other assignment of


                                                                Initial_________
                                                                       _________

<PAGE>   22
such sublease to Lessor, nor by reason of the collection of the rents from a
sublessee, be deemed liable to the sublessee for any failure of Lessee to
perform and comply with any of Lessee's obligations to such sublessee under such
Sublease. Lessee hereby irrevocably authorizes and directs any such sublessee,
upon receipt of a written notice from Lessor stating that a Breach exists in the
performance of Lessee's obligations under this Lease, to pay to Lessor the rents
and other charges due and to become due under the sublease. Sublessee shall rely
upon any such statement and request from Lessor and shall pay such rents and
other charges to Lessor without any obligation or right to inquire as to whether
such Breach exists and notwithstanding any notice from or claim from Lessee to
the contrary. Lessee shall have no right or claim against such sublessee, or,
until the Breach has been cured, against Lessor, for any such rents and other
charges so paid by said sublessee to Lessor.

                  (b)      In the event of a Breach by Lessee in the performance
of Its obligations under this Lease, Lessor, at its option and without any
obligation to do so, may require any sublessee to attorn to Lessor, in which
event Lessor shall undertake the obligations of the sublessor under such
sublease from the time of the exercise of said option to the expiration of such
sublease; provided, however, Lessor shall not be liable for any prepaid rents or
security deposit paid by such sublessee to such sublessor or for any other prior
defaults or breaches of such sublessor under such sublease.

                  (c)      Any matter or thing requiring the consent of the
sublessor under a sublease shall also require the consent of Lessor herein.

                  (d)      No sublessee under a sublease approved by Lessor
shall further assign or sublet all or any part of the Premises without Lessor's
prior written consent.

                  (e)      Lessor shall deliver a copy of any notice of Default
or Breach by Lessee to the sublessee, who shall have the right to cure the
Default of Lessee within the grace period, if any, specified in such notice. The
sublessee shall have a right of reimbursement and offset from and against Lessee
for any such Defaults cured by the sublessee.

13.      DEFAULT; BREACH; REMEDIES.

         13.1     DEFAULT; BREACH. Lessor and Lessee agree that if an attorney
is consulted by Lessor in connection with a Lessee Default or Breach (as
hereinafter defined), $350.00 is a reasonable minimum sum per such occurrence
for legal services and costs in the preparation and service of a notice of
Default, and that Lessor may include the cost of such services and costs in said
notice as rent due and payable to cure said default. A "DEFAULT" by Lessee is
defined as a failure by Lessee to observe, comply with or perform any of the
terms, covenants, conditions or rules applicable to Lessee under this Lease. A
"BREACH" by Lessee is defined as the occurrence of any one or more of the
following Defaults, and, where a grace period for cure after notice is specified
herein, the failure by Lessee to cure such Default prior to the expiration of
the applicable grace period, and shall entitle Lessor to pursue the remedies set
forth in Paragraphs 13.2 and/or 13.3:

                  (a)      The vacating of the Premises without the intention to
reoccupy same, or the abandonment of the Premises.

                  (b)      Except as expressly otherwise provided in this Lease,
the failure by Lessee to make any payment of Base Rent, Lessee's Share of Common
Area Operating Expenses, or any other monetary payment required to be made by
Lessee hereunder as and when due, the failure by Lessee to provide Lessor with
reasonable evidence of insurance or surety bond required under this Lease, or
the failure of Lessee to fulfill any obligation under this Lease which endangers
or threatens life or property, where such failure continues for a period of
three (3) days following written notice thereof by or on behalf of Lessor to
Lessee.

                                                                Initial_________
                                                                       _________

<PAGE>   23
                  (c)      Except as expressly otherwise provided in this Lease,
the failure by Lessee to provide Lessor with reasonable written evidence (in
duly executed original form, if applicable) of (i) compliance with Applicable
Requirements per Paragraph 6.3, (ii) the inspection, maintenance and service
contracts required under Paragraph 7.1 (b), (iii) the rescission of an
unauthorized assignment or subletting per Paragraph 12.1, (iv) a Tenancy
Statement per Paragraphs 16 or 37, (v) the subordination or non-subordination of
this Lease per Paragraph 30, (vi) the guaranty of the performance of Lessee's
obligations under this Lease if required under Paragraphs 1.11 and 37, (vii) the
execution of any document requested under Paragraph 42 (easements), or (viii)
any other documentation or information which Lessor may reasonably require of
Lessee under the terms of this lease, where any such failure continues for a
period of ten (10) days following written notice by or on behalf of Lessor to
Lessee.

                  (d)      A Default by Lessee as to the terms, covenants,
conditions or provisions of this Lease, or of the rules adopted under Paragraph
40 hereof that are to be observed, compiled with or performed by Lessee, other
than those described in Subparagraphs 13.1 (a), (b) or (c), above, where such
Default continues for a period of thirty (30) days after written notice thereof
by or on behalf of Lessor to Lessee; provided, however, that if the nature of
Lessee's Default is such that more than thirty (30) days are reasonably required
for its cure, then it shall not be deemed to be a Breach of this Lease by Lessee
if Lessee commences such cure within said thirty (30) day period and thereafter
diligently prosecutes such cure to completion.

                  (e)      The occurrence of any of the following events: (i)
the making by Lessee of any general arrangement or assignment for the benefit of
creditors; (ii) Lessee's becoming a "debtor" as defined in 11 U.S. Code Section
101 or any successor statute thereto (unless, in the case of a petition filed
against Lessee, the same is dismissed within sixty (60) days); (iii) the
appointment of a trustee or receiver to take possession of substantially all of
Lessee's assets located at the Premises or of Lessee's interest in this Lease,
where possession is not restored to Lessee within thirty (30) days; or (iv) the
attachment, execution or other judicial seizure of substantially all of Lessee's
assets located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days; provided, however, in the
event that any provision of this Subparagraph 13.1 (e) is contrary to any
applicable law, such provision shall be of no force or effect, and shall not
affect the validity of the remaining provisions.

                  (f)      The discovery by Lessor at any financial statement of
Lessee or of any Guarantor, given to Lessor by lessee or any Guarantor, was
materially false.

                  (g)      If the performance of Lessee's obligations under this
Lease is guaranteed; (i) the death of a Guarantor, (ii) the termination of a
Guarantor's liability with respect to this Lease other than in accordance with
the terms of such guaranty, (iii) a Guarantor's becoming insolvent or the
subject of a bankruptcy filing, (iv) a Guarantor's refusal to honor the
guaranty, or (v) a Guarantor's breach of its guaranty obligation on an
anticipatory breach basis, and Lessee's failure, within sixty (60) days
following written notice by or on behalf of Lessor to Lessee of any such event,
to provide Lessor with written alternative assurances of security, which, when
coupled with the then existing resources of Lessee, equals or exceeds the
combined financial resources of Lessee and the Guarantors that existed at the
time of execution of this Lease.

         13.2     REMEDIES. If Lessee fails to perform any affirmative duty or
obligation of Lessee under this Lease, within ten (10) days after written notice
to Lessee (or in case of an emergency, without notice), Lessor may at its option
(but without obligation to do so), perform such duty or obligation on Lessee's
behalf, including, but not limited to the obtaining of reasonably required
bonds, insurance policies, or governmental licenses, permits or approvals. The
costs and expenses of any such performance by Lessor shall be due and payable by
Lessee to Lessor upon invoice therefor. If any check given to Lessor by Lessee
shall not be honored by the bank upon which it is

                                                                Initial_________
                                                                       _________

drawn, Lessor, at its own option, may require all future payments to be made
under this Lease by Lessee to be made only by cashier's check. In the event of a
Breach of the Lease by Lessee (as defined in Paragraph 13.1), with or without
further notice or demand, and without limiting Lessor in the exercise of any
right or remedy which Lessor may have by reason of such Breach, Lessor may:

                  (a)      Terminate Lessee's right to possession of the
Premises by any lawful means, in which case this Lease and the term hereof shall
terminate and Lessee shall immediately surrender possession of the Premises to
Lessor. In such event Lessor shall be entitled to recover from Lesseee: (i) the
worth at the time of the award of the unpaid rent which had been earned at the
time of termination; (ii) the worth at the time of award of the amount by which
the unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that the Lessee proves could have
been reasonably avoided; (iii) the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease for which in the ordinary course of things would be
likely to result therefrom, including but not limited to the cost of recovering
possession of the Premises, expenses of reletting, including necessary
renovation and alternation of the Premises, reasonable attorney's fees and that
portion of any leasing commission paid by Lessor in connection with this Lease
applicable to the unexpired term of this Lease. The worth at the time of award
of the amount referred to in provision (iii) of the immediately preceding
sentence shall be computed by discounting such amount at the discount rate of
the Federal Reserve Bank of San Francisco or the Federal Reserve Bank District
in which the Premises are located at the time of award plus one percent (1%).
Efforts by Lessor to mitigate damages caused by Lessee's Default or Breach of
this Lease shall not waive Lessor's right to recover damages under this
Paragraph 13.2. If termination of this Lease is obtained through the provisional
remedy of unlawful detainer, Lessor shall have the right to recover in such
proceeding the unpaid rent and damages as are recoverable therein, or Lessor,
may reserve the right to recover all or any part thereof in a separate suit for
such rent and/or damages. If a notice and grace period required under
Subparagraph 13.1 (b), (c) or (d) was not previously given, a notice to pay rent
or quit, or to perform or quit, as the case may be, given to Lessee under any
statute authorizing the forfeiture of leases for unlawful detainer shall also
constitute the applicable notice for grace period purposes required by
Subparagraph 13.1 (b),(c) or (d). In such case, the applicable grace period
under the unlawful detainer statue shall run concurrently after the one such
statutory notice, and the failure of Lessee to cure the Default within the
greater of the two (2) such grace periods shall constitute both an unlawful
detainer and a Breach of this Lease entitling Lessor to the remedies provided
for in this Lease and/or by said statute.

                  (b)      Continue the Lease and Lessee's right to possession
in effect (in California under California Civil Code Section 1951.4) after
Lessee's Breach and recover the rent as it becomes due, provided Lessee has the
right to sublet or assign, subject only to reasonable limitations. Lessor and
Lessee agree that the limitations on assignment and subletting in this Lease are
reasonable. Acts of maintenance or preservation. efforts to relet the Premises,
or the appointment of a receiver to protect the Lessor's interest under this
Lease, shall not constitute a termination of the Lessee's right to possession.

                  (c)      Pursue any other remedy now or hereafter available to
Lessor under the laws or judicial decisions of the state wherein the Premises
are located.

                  (d)      The expiration or termination of this Lease and/or
the termination of Lessee's right to possession shall not relieve Lessee from
liability under any indemnity provisions of this Lease as to matters occurring
or accruing during the term hereof or by reason of Lessee's occupancy of the
Premises.

         13.3     INDUCEMENT RECAPTURE IN EVENT OF BREACH. Any agreement by
Lessor for free or abated rent or other charges applicable to the Premises, or
for the giving or paying by Lessor to or for Lessee of any cash or other

                                                                Initial_________

bonus, inducement or consideration for Lessee's entering into this Lease, all of
which concessions are hereinafter referred to as "INDUCEMENT PROVISIONS" shall
be deemed conditioned upon Lessee's full and faithful performance of all of the
terms, covenants and conditions of this Lease to be performed, or observed by
Lessee during the term hereof as the same may be extended. Upon the occurrence
of a Breach (as defined in Paragraph 13.1) of this Lease by Lessee, any such
Inducement Provision shall automatically be deemed deleted from this Lease and
of no further force or effect, and any rent, other charge, bonus, inducement or
consideration theretofore abated, given or paid by Lessor under such an
Inducement Provision shall be immediately due and payable by Lessee to Lessor,
and recoverable by Lessor, as additional rent due under this Lease,
notwithstanding any subsequent cure of said Breach by Lessee. The acceptance by
Lessor of rent or the cure of the Breach which initiated the operation of this
Paragraph 13.3 shall not be deemed a waiver by Lessor of the provisions of this
Paragraph 13.3 unless specifically so stated in writing by Lessor at the time of
such acceptance.

         13.4     LATE CHARGES. Lessee hereby acknowledges that late payment by
Lessee to Lessor of rent and other sums due hereunder will cause Lessor to incur
costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain. Such costs include, but are not limited to,
processing and accounting charges, and late charges which may be imposed upon
Lessor by the terms of any ground lease, mortgage or deed of trust covering the
Premises. Accordingly, if any installment of rent or other sum due from Lessee
shall not be received by Lessor or Lessor's designee within ten (10) days after
such amount shall be due, then, without any requirement for notice to Lessee,
Lessee shall pay to Lessor a late charge equal to six percent (6%) of such
overdue amount. The parties hereby agree that such late charge represents a fair
and reasonable estimate of the costs Lessor will incur by reason of late payment
by Lessee. Acceptance of such late charge by Lessor shall in no event constitute
a waiver of Lessee's Default or Breach with respect to such overdue amount, nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder. In the event that a late charge is payable hereunder, whether or not
collected, for three (3) consecutive installments of Base Rent, then
notwithstanding Paragraph 4.1 or any other provision of this Lease to the
contrary, Base Rent shall, at Lessor's option, become due and payable quarterly
in advance.

         13.5     BREACH BY LESSOR. Lessor shall not be deemed in breach of this
Lease unless Lessor fails within a reasonable time to perform an obligation
required to be performed by Lessor. For purposes of this Paragraph 13.5, a
reasonable time shall in no event be less than thirty (30) days after receipt by
Lessor, and by any Lender(s) whose name and address shall have been furnished to
Lessee in writing for such purpose, of written notice specifying wherein such
obligation of Lessor has not been performed; provided, however, that if the
nature of Lessor's obligation is such that more than thirty (30) days after such
notice are reasonably required for its performance, then Lessor shall not be in
breach of this Lease if performance is commenced within such thirty (30) day
period and thereafter diligently pursued to completion.

14.      CONDEMNATION. If the Premises or any portion thereof are taken under
the power of eminent domain or sold under the threat of the exercise of said
power (all of which are herein called "condemnations"), this Lease shall
terminate as to the part so taken as of the date the condemning authority takes
title or possession, whichever first occurs. If more than ten percent (10%) of
the floor area of the Premises, or more than twenty-five percent (25%) of the
portion of the Common Areas designated for Lessee's parking, is taken by
condemnation, Lessee may, at Lessee's option, to be exercised in writing within
ten (10) days after Lessor shall have given Lessee written notice of such taking
(or in the absence of such notice, within ten (10) days after the condemning
authority shall have taken possession) terminate this Lease as of the date the
condemning authority takes such possession. If Lessee does not terminate this
Lease in accordance with the foregoing, this Lease shall remain in full force
and effect as to the portion of the Premises remaining, except that the Base
Rent shall be reduced in the same proportion as the rentable floor area of the
Premises taken bears to the total rentable floor area of the Premises. No
reduction of Base Rent shall occur if the condemnation does not apply to any
portion of the Premises. Any award for the taking of all or any part of the
Premises under the power of eminent domain or any payment made under threat of
the exercise of


                                                                Initial_________
                                                                       _________

such power shall be the property of Lessor, whether such award shall be made as
compensation for diminution of value of the leasehold or for the taking of the
fee, or as severance damages; provided, however, that Lessee shall be entitled
to any compensation, separately awarded to Lessee for Lessee's relocation
expenses and/or loss of Lessee's Trade Fixtures. in the event that this Lease is
not terminated by reason of such condemnation, Lessor shall to the extent of its
net severance damages received, over and above Lessee's Share of the legal and
other expenses incurred by lessor in the condemnation matter, repair any damage
to the Premises caused by such condemnation authority. Lessee shall be
responsible for the payment of any amount in excess of such net severance
damages required to complete such repair.

15.      BROKERS' FEES.

         15.1     PROCURING CAUSE. The Broker(s) named in Paragraph 1.10 is/are
the procuring cause of this Lease.

         15.2     ADDITIONAL TERMS. Unless Lessor and Broker(s) have otherwise
agreed in writing, Lessor agrees that: (a) if Lessee exercises any Option (as
defined In Paragraph 39.1) granted under this Lease or any Option subsequently
granted, or (b) if Lessee acquires any rights to the Premises or other premises
in which Lessor has an interest, or (c) if Lessee remains in possession of the
Premises with the consent of Lessor after the expiration of the term of this
Lease after having failed to exercise an Option, or (d) if said Brokers are the
procuring cause of any other lease or sale entered into between the Parties
pertaining to the Premises and/or any adjacent property in which Lessor has an
interest, or (e) if Base Rent is increased, whether by agreement or operation of
an escalation clause herein, then as to any of said transactions, Lessor shall,
pay said Broker(s) a fee in accordance with the schedule of said Broker(s) in
effect at the time of the execution of this Lease.

         15.3     ASSUMPTION OF OBLIGATIONS. Any buyer or transferee of Lessor's
Interest in this Lease, whether such transfer is by agreement or by operation of
law, shall be deemed to have assumed Lessors obligation under this Paragraph 15.
Each Broker shall be an intended third party beneficiary of the provisions of
Paragraph 1.10 and of this Paragraph 15 to the extent of its interest in any
commission arising from this Lease and may enforce that right directly against
Lessor and its successors.

         15.4     REPRESENTATIONS AND WARRANTIES. Lessee and Lessor each
represent and warrant to the other that it has had no dealings with any person,
firm, broker or finder other than as named in Paragraph 1.10(a) in connection
with the negotiation of this Lease and/or the consummation of the transaction
contemplated hereby, and that no broker or other person, firm or entity other
than said named Broker(s) is entitled to any commission or finder's fee in
connection with said transaction. Lessee and Lessor do each hereby agree to
indemnify, protect, defend and hold the other harmless from and against
liability for compensation or charges which may be claimed by any such unnamed
broker, finder or other similar party by reason of any dealings or actions of
the indemnifying Party, including any costs, expenses, and/or attorneys' fees
reasonably incurred with respect thereto.

16.     TENANCY AND FINANCIAL STATEMENTS.

         16.1     TENANCY STATEMENT. Each Party (as "RESPONDING PARTY") shall
within ten (10) days after written notice from the other Party (the ("REQUESTING
PARTY") execute, acknowledge and deliver to the Requesting Party a statement in
writing in a form similar to the then most current "TENANCY STATEMENT" form
published by the American Industrial Real Estate Association, plus such
additional information, confirmation and/or statements as may be reasonably
requested by the Requesting Party.

         16.2     FINANCIAL STATEMENT. If Lessor desires to finance, refinance,
or sell the Premises or the Building, or any part thereof, Lessee and all
Guarantors shall deliver to any potential lender or purchaser designated

                                                                Initial_________

by Lessor such financial statements of Lessee and such Guarantors as may be
reasonably required by such lender or purchaser, including but not limited to
Lessee's financial statements for the past three (3) years. All such financial

event of a transfer of Lessor's title or interest in the Premises or in this
Lease, Lessor shall deliver to the transferee or assignee (in cash or by credit)
any unused Security Deposit held by Lessor at the time of such transfer or
assignment. Except as provided in Paragraph 15.3, upon such transfer or
assignment and delivery of the Security Deposit, as aforesaid, the prior Lessor
shall be relieved of all liability with respect to the obligations and/or
covenants under this Lease thereafter to be performed by the Lessor. Subject to
the foregoing, the obligations and/or covenants in this Lease to be performed by
the Lessor shall be binding only upon the Lessor as hereinabove defined.

hereunder, other than late charges, not received by Lessor within ten (10) days
following the date on which it was due, shall bear interest from the date due at

maximum rate allowed by law, in addition to the potential late charge provided
for in Paragraph 13.4.

of all obligations to be performed or observed by the Parties under this Lease.

22.      NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER. This Lease contains
all agreements between the Parties with respect to any matter mentioned
herein, and no other prior or contemporaneous agreement or understanding shall
be effective. Lessor and Lessee each represents and warrants to the Brokers that
it has made, and is relying solely upon its own investigation as to the nature,
quality, character and financial responsibility of the other Party to this Lease
and as to the nature, quality and character of the Premises. Brokers have no
responsibility with respect thereto or with respect to any default to breach
hereof by either Party. Each Broker shall be an intended third party beneficiary

adjacent to a Party's signature on this Lease shall be that Party's address for
delivery or mailing of notice purposes. Either Party may by written notice to
the other specify a different address for notice purposes, except that upon
Lessee's taking possession of the Premises, the Premises shall constitute
Lessee's address for the purpose of mailing or delivering notices to Lessee. A
copy of all notices required or permitted to be given to Lessor hereunder shall
be concurrently transmitted to such party or parties at such addresses as Lessor
may from time to time hereafter designate by written notice to Lessee.

         23.2     DATE OF NOTICE. Any notice sent by registered or certified
mail, return receipt requested, shall be deemed given on the date of delivery
shown on the receipt card, or if no delivery date is shown, the postmark
thereon. If sent by regular mail, the notice shall be deemed given forty-eight
(48) hours after the same is addressed as required herein and mailed with
postage prepaid. Notices delivered by United States Express Mail or overnight
courier that guarantees next day delivery shall be deemed given twenty-four (24)

or a legal holiday, it shall be deemed received on the next business day.

24.      WAIVERS. No waiver by Lessor of the Default or Breach of any term,
covenant or condition hereof by Lessee, shall be deemed a waiver of any other
term, covenant or condition hereof, or of any subsequent Default or Breach by
Lessee of the same or any other term, covenant or condition hereof. Lessor's
consent to, or approval of, any such act shall not be deemed to render
unnecessary the obtaining of Lessor's consent to, or approval of, any subsequent
or similar act by Lessee, or be construed as the basis of an estoppel to enforce
the provision or provisions of this Lease requiring such consent. Regardless of
Lessor's knowledge of a Default or Breach at the time of accepting rent, the
acceptance of rent by Lessor shall not be a waiver of any Default or Breach by
Lessee of any provision hereof. Any payment given Lessor by Lessee may be
accepted by Lessor on account of moneys or damages due Lessor, notwithstanding
any qualifying statements or conditions made by Lessee in connection therewith,
which such statements and/or conditions shall be of no force or effect
whatsoever unless specifically agreed to in writing by Lessor at or before the
time of deposit of such payment.

execute, acknowledge and deliver to the other a short form memorandum of this
Lease for recording purposes. The Party requesting recordation shall be

26.      NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of

26 then the Base Rent payable from and after the time of the expiration or
earlier termination of this Lease shall be increased to two hundred percent
(200%) of the Base Rent applicable during the month immediately preceding such
expiration or earlier termination. Nothing contained herein shall be construed
as a consent by Lessor to any holding over by Lessee.

27.      CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28.      COVENANTS AND CONDITIONS. All provisions of this Lease to be observed
or performed by Lessee are both covenants and conditions.

29.      BINDING EFFECT; CHOICE OF LAW. This Lease shall be binding upon the
Parties, their personal representatives, successors and assigns and be governed
by the laws of the State in which the Premises are located. Any litigation
between the Parties hereto concerning this Lease shall be initiated In the
county in which the Promises are located.

30.      SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

         30.1     SUBORDINATION. This Lease and any Option granted hereby shall
be subject and subordinate to any ground lease, mortgage, deed of trust, or
other hypothecation or security device (collectively, "SECURITY DEVICE"), now or
hereafter placed by Lessor upon the real property of which the Premises are a
part, to any and all advances made on the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. Lessee
agrees that the Lenders holding any such Security Device shall have no duty,
liability or obligation to perform any of the obligations of Lessor under this
Lease, but that in the event of Lessor's default with respect to any such
obligation, Lessee will give any Lender whose name and address have been
furnished Lessee in writing for such purpose notice of Lessor's default pursuant
to Paragraph 13.5. If any Lender shall elect to have this Lease and/or any
Option granted hereby superior to the lien of its Security Device and shall give
written notice thereof to Lessee, this Lease and such Options shall be deemed
prior to such Security Device, notwithstanding the relative dates of the
documentation or recordation thereof.

         30.2     ATTORNMENT. Subject to the non-disturbance provisions of
Paragraph 30.3, Lessee agrees to attorn to a Lender or any other party who
acquires ownership of the Premises by reason of a foreclosure of a Security
Device, and that in the event of such foreclosure, such new owner shall not: (i)
be liable for any act or omission of any prior lessor or with respect to events
occurring prior to acquisition of ownership, (ii) be subject to any offsets or
defenses which Lessee might have against any prior lessor, or (iii) be bound by
prepayment of more than one month's rent.

         30.3     NON-DISTURBANCE. With respect to Security Devices entered into
by Lessor after the execution of this lease, Lessee's subordination of this
Lease shall be subject to receiving assurance (a "non-disturbance agreement")
from the Lender that Lessee's possession and this Lease, including any options
to extend the term hereof, will not be disturbed so long as Lessee is not in
Breach hereof and attorns to the record owner of the Premises.

         30.4     SELF-EXECUTING. The agreements contained in this Paragraph 30
shall be effective without the execution of any further documents; provided,
however, that upon written request from Lessor or a Lender in connection with a
sale, financing or refinancing of Premises, Lessee and Lessor shall execute such
further writings as may be reasonably required to separately document any such
subordination or non-subordination, attornment and/or non-disturbance agreement
as is provided for herein.

31.      ATTORNEYS' FEES. If any Party or Broker brings an action or proceeding
to enforce the terms hereof or declare rights hereunder, the Prevailing Party
(as hereafter define) in any such proceeding, action, or appeal thereon, shall
be entitled to reasonable attorneys' fees. Such fees may be awarded in the same
suit or recovered in a separate suit, whether or not such action or proceeding
is pursued to decision or judgment. The term "PREVAILING PARTY" shall include,
without limitation, a Party or Broker who substantially obtains or defeats the
relief sought, as the case may be, whether by compromise, settlement, judgment,
or the abandonment by the other Party or Broker of its claim or defense. The
attorneys' fee award shall not be computed in accordance with any court fee
schedule, but shall be such as to fully reimburse all attorneys' fees reasonably
incurred. Lessor shall be entitled to attorneys' fees, costs and expenses
incurred in preparation and service of notices of Default and consultations in
connection therewith, whether or not a legal action is subsequently commenced in
connection with such Default or resulting Breach. Broker(s) shall be intended
third party beneficiaries of this Paragraph 31.

32.      LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS. Lessor and Lessor's agents
shall have the right to enter the Premises at any time, in the case of an
emergency, and otherwise at reasonable times for the purpose of showing the same
to prospective purchasers, lenders, or lessees, and making such alterations,
repairs, improvements or additions to the Premises or to the Building, as Lessor
may reasonably deem necessary. Lessor may at any time place on or


                                                                Initial_________

<PAGE>   30
about the Premises or Building any ordinary "For Sale" signs and Lessor may at
any time during the last one hundred eighty (180) days of the term hereof place
on or about the Premises any ordinary "For Lease" signs. All such activities of
Lessor shall be without abatement of rent or liability to Lessee.

33.      AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises without first having
obtained Lessor's prior written consent. Notwithstanding anything to the
contrary in this Lease, Lessor shall not be obligated to exercise any standard
of reasonableness in determining whether to grant such consent.

34.      SIGNS. Lessee shall not place any sign upon the exterior of the
Premises or the Building, except that Lessee may, with Lessor's prior written
consent, install (but not on the roof) such signs as are reasonably required to
advertise Lessee's own business so long as such signs are in a location
designated by Lessor and comply with Applicable Requirements and the signage
criteria established for the Industrial Center by Lessor. The installation of
any sign on the Premises by or for Lessee shall be subject to the provisions of
Paragraph 7 (Maintenance, Repairs, Utility Installations, Trade Fixtures and
Alterations). Unless otherwise expressly agreed herein, Lessor reserves all
rights to the use of the roof of the Building, and the right to install ,
advertising signs on the Building, including the roof, which do not unreasonably
interfere with the conduct of Lessee's business; Lessor shall be entitled to all
revenues from such advertising signs.

35.      TERMINATION; MERGER. Unless specifically stated otherwise in writing by
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual
termination or cancellation hereof, or a termination hereof by Lessor for Breach
by Lessee, shall automatically terminate any sublease or lesser estate in the
Premises; provided, however, Lessor shall, in the event of any such surrender,
termination or cancellation, have the option to continue any one or all of any
existing subtenancies. Lessor's failure within ten (10) days following any such
event to make a written election to the contrary by written notice to the holder
of any such lesser interest, shall constitute Lessor's election to have such
event constitute the termination of such interest.

36.      CONSENTS.

                  (a)      Except for Paragraph 33 hereof (Auctions) or as
otherwise provided herein, wherever in this Lease the consent of a Party is
required to an act by or for the other Party, such consent shall not be
unreasonably withheld or delayed. Lessor's actual reasonable costs and expenses
(including but not limited to architects', attorneys', engineers' and other
consultants' fees) incurred in the consideration of, or response to, a request
by Lessee for any Lessor consent pertaining to this Lease or the Premises,
including but not limited to consents to an assignment a subletting or the
presence or use of a Hazardous Substance, shall be paid by Lessee to Lessor upon
receipt of an invoice and supporting documentation therefor. In addition to the
deposit described in Paragraph 12.2 (e), Lessor may, as a condition to
considering any such request by Lessee, require that Lessee deposit with Lessor
an amount of money (in addition to the Security Deposit held under Paragraph 5)
reasonably calculated by Lessor to represent the cost Lessor will incur in
considering and responding to Lessee's request. Any unused portion of said
deposit shall be refunded to Lessee without interest. Lessor's consent to any
act, assignment of this Lease or subletting of the Premises by Lessee shall not
constitute an acknowledgment that no Default or Breach by Lessee of this Lease
exists, nor shall such consent be deemed a waiver of any then existing Default
or Breach, except as may be otherwise specifically stated in writing by Lessor
at the time of such consent.

                  (b)      All conditions to Lessor's consent authorized by this
Lease are acknowledged by Lessee as being reasonable. The failure to specify
herein any particular condition to Lessor's consent shall not preclude the
impositions by Lessor at the time of consent of such further or other conditions
as are then reasonable with reference to the particular matter for which consent
is being given.

                                                                Initial_________

<PAGE>   3
         approve. It shall provide by endorsement or otherwise that such
         insurance may not be cancelled, terminated, amended or modified for any
         reason whatsoever, except upon thirty (30) days' prior written notice
         to Lessor.

                  (c) Prior to the time the fire, extended coverage, casualty
         and liability insurance required by this Section is first required to
         be carried by a party hereto, and thereafter at least fifteen (15) days
         prior to the expiration of any such policy, the party responsible for
         maintaining- the same shall deliver to the other party either duplicate
         originals of the aforesaid policies or a certificate evidencing such
         insurance coverage together with evidence of payment for the policies.
         In addition, any fire, extended coverage and casualty insurance policy
         maintained by Lessor or Lessee with respect to the Grand Rapids Plant
         or the content thereof, shall contain a clause or endorsement under
         which the insurer waives, or permits the waiver by the insured
         thereunder, of all rights of subrogation against the other party
         hereto, and its agents, employees, customers, invitees, guests or
         licensees, with respect to losses payable under such policy.
         Notwithstanding the provisions of Section 8 below, the parties hereto
         waive all right of recovery which they might otherwise have against one
         another, and their respective agents, employees, customers, invitees,
         guests or licensees, for any damage to their respective properties
         which is covered by a policy of insurance, notwithstanding that such
         damage may result from the negligence or fault of the other party, or
         its agents, employees, customers, invitees, guests or licensees.


         4. Obligation to Pay Taxes. Lessor shall pay all real estate taxes and
installments of special assessments last due and payable without penalty on the
Grand Rapids Plant during the period commencing September 1, 1986, and ending
December 31, 1987, before the same are delinquent, without proration.
Thereafter, during the term of this Lease and any extensions, Lessee shall pay
all real estate taxes and installments of special assessments with respect to
the Grand Rapids Plant before the same are delinquent, without proration, and
indemnify Lessor against any liability therefor. The party responsible for the
payment of such taxes and assessments shall, upon request, promptly provide
evidence of payment to the other party.


         5. Maintenance and Repair Obligation. Lessee shall keep and maintain
the Grand Rapids Plant in good and clean order, condition and repair at all
times during the term of this Lease and any extensions, and will deliver the
same to Lessor at the expiration of the term in as good condition as when
received, except for reasonable use and wear thereof, and as provided in Section
12 below; provided, however, that Lessor shall reimburse Lessee for the
out-of-pocket cost in excess of $500 of any single item of repair or replacement
which was approved in advance by Lessor (which approval shall not be
unreasonably withheld). Lessee shall, at its sole expense, enter into and
maintain during the term of this Lease and any extensions, a contract for the
provision and maintenance of a security system for the Grand Rapids Plant, and
contracts for the regular repair and maintenance of the boiler and elevators
located in the Grand Rapids Plant, all of which shall be in form and substance
reasonably acceptable -to Lessor; provided, however, that Lessee may elect to
have an employee of Lessee maintain the boiler and/or elevators if Lessor first
consents to such arrangement. Lessor shall not unreasonably withhold or delay
such




                                      -3-
<PAGE>   4
consent; provided that Lessee demonstrates to Lessor that the employee is

without limitation, responsibility for: (a) compliance with all applicable laws,
ordinances and regulations; (b) certification of boilers and elevators; (c)
cleaning, lawn maintenance, snowplowing and snow removal; and (d) replacement of
broken windows.


         6. Obligation to Pay for Utilities. Lessee shall pay for all costs of
heat, light, power, telephone and other utilities it desires, used at the Grand
Rapids Plant during the term of this Lease and any extensions. Lessor shall not
be liable to Lessee in damages or otherwise for any failure or interruption of
any utility service furnished to the Grand Rapids Plant.


         7. Peaceable Enjoyment, Right to Sublet and Office Facility for Lessor.
During the term of this Lease and any extensions, Lessee shall have the sole and
exclusive right to occupancy of the Grand Rapids Plant, and to the peaceable
enjoyment thereof, including the right to sublease all or any portion(s) of the
Grand Rapids Plant to any person(s) of its selection, so long as it is not then
in default of any of its obligations hereunder, and so long as it first obtains
the written consent of Lessor to such subletting, which consent shall not be
unreasonably withheld or delayed; provided, however, that Lessor shall have the
right to continue to occupy its current office facility in the Grand Rapids
Plant or such other space comprising at least 400 to 500 square feet upon which
the parties shall mutually agree, and to continue its exclusive use of the
fireproof room identified in Exhibit A for the storage of its records, as a
subtenant of Lessee, without any obligation for the payment of rent, for the
period ending August 31, 1987, with a right to extend upon terms mutually agreed
upon between Lessor and Lessee. Lessor's consent to any assignment or subletting
shall not be construed as a consent to any further assignment or subletting and
shall in no event release Lessee from any liability hereunder. Lessor shall have
24 hour security clearance with EPS or any other security firm employed by
Lessee for the office area of the Grand Rapids Plant until August 31, 1987.
Thereafter, Lessor shall have access to any portion of the Grand Rapids Plant
occupied or used by it pursuant to this Section during normal business hours
and, with Lessee's prior consent, during non-business hours.


         8. Mutual Indemnification. Each party hereto shall indemnify the other
against and hold it harmless from any and all liabilities, obligations, damages,
penalties, claims, costs and expenses, including, without limitation, reasonable
attorneys' fees, paid or incurred as a result of or in connection with (i) such
party's ownership, use or occupancy of the Grand Rapids Plant, (ii) any breach
by such party, any subtenant or any of their agents, contractors, employees,
customers, invitees or licensees, of any covenant or condition of this Lease, or
(iii) the carelessness, negligence or improper conduct of such party, any
subtenant, or any of their contractors, employees, customers, invitees or
licensees. If any action or proceeding is brought against the other party by
reason of such claim, the indemnifying party, upon written notice from the other
party, will, at the indemnifying party's expense, resist or defend such action
or proceeding by counsel approved by the other party in writing.



                                      -4-
<PAGE>   5
         9. Use of Grand Rapids Plant. Lessee shall use and occupy the Grand
Rapids Plant for office, warehouse and manufacturing purposes, and for no other
purpose whatsoever. Lessee shall not use the Grand Rapids Plant, or permit the
Grand Rapids Plant to be used, in a manner that constitutes a violation of any
applicable law, ordinance, order or regulation, or that may be dangerous; nor
shall Lessee commit any waste in the Grand Rapids Plant, or permit any
objectionable noise or odor to be emitted, or permit anything to be done in the
Grand Rapids Plant tending to create a nuisance or disturb others.


         10. Condition of Grand Rapids Plant. As Lessee has used and occupied
the Grand Rapids Plant for some time, Lessee is quite familiar with the current
condition of the Grand Rapids Plant. Lessee acknowledges that it has inspected
the Grand Rapids Plant, found it to be in satisfactory condition for its
intended use and accepts the Grand Rapids Plant in its current "AS IS"
condition, with no warranties whatsoever concerning its condition or permitted
use.


         11. Alterations and Additions. Lessee may not alter or add to the Grand
Rapids Plant without Lessor's prior written consent, which consent shall not be
unreasonably withheld or delayed. Lessor shall have no obligation to make any
alteration or addition to the Grand Rapids Plant during the term. All right,
title and interest to any alterations and additions to the Grand Rapids Plant
during the term, except for trade fixtures and removable equipment, shall be the
property of Lessor and shall be deemed to be a part of the Grand Rapids Plant,
and shall remain on, and be surrendered with the Grand Rapids Plant upon the
termination of this Lease, without cost or expense to Lessor.


         12. Restoration.

                  (a) If the Grand Rapids Plant is damaged or destroyed, in
         whole or in part, Lessee shall repair, restore, replace or rebuild the
         Grand Rapids Plant, or the part thereof so damaged, as nearly as
         possible to the value, condition and character of the Grand Rapids
         Plant immediately prior to the occurrence of such damage or
         destruction. Lessee shall not be entitled to an abatement of rent
         during the construction period.

                  (b) All insurance proceeds payable as a result of any damage
         to or destruction of the Grand Rapids Plant shall be paid to Lessor and
         shall be disbursed by Lessor to Lessee as reconstruction work
         progresses. If the insurance proceeds are insufficient to pay for all
         restoration work, then Lessee shall pay any additional amounts
         necessary to restore the Grand Rapids Plant. Upon completion of the
         restoration, and payment for all restoration work, all remaining
         insurance proceeds shall be retained by Lessor.

                  (c) Notwithstanding the foregoing provisions of this Section,
         if the damage to or destruction of the Grand Rapids Plant cannot be
         repaired within one hundred twenty (120) days of the damage, either
         Lessor or Lessee may terminate this Lease by giving ten (10) days'
         prior written notice to the other party within thirty (30) days after
         the damage




                                      -5-
<PAGE>   6
         or destruction occurs. If the Lease is terminated pursuant to this
         subsection, all insurance proceeds payable as a result of the damage or
         destruction shall be retained by Lessor.

                  (d) The provisions of this Section shall not apply to the
         proceeds of any policy of business interruption insurance which Lessee
         may place to cover its operations in the Grand Rapids Plant, all
         proceeds of which policy shall be and remain the property of the
         Lessee.


         13. Condemnation. If all or any substantial part of the Grand Rapids
Plant is taken or condemned by a governmental authority, or shall be conveyed by
Lessor under a threat of such taking or condemnation, the rights and obligations
of Lessor and Lessee with respect to such taking or condemnation shall be as
provided in this Section. If twenty-five percent (25%) or more of the gross
floor area within the Grand Rapids Plant is so taken, condemned or conveyed,
this Lease shall terminate as of the date of such taking, condemnation or
conveyance, and rent shall be prorated as of such date. If less than twenty-five
percent (25%) of the gross floor area within the Grand Rapids Plant is taken,
condemned or conveyed, this Lease shall remain in effect; provided, however,
that the rent payable by Lessee shall be reduced for the remainder of the term
in the same proportion which the number of square feet of gross floor area
within the buildings comprising the Grand Rapids Plant following such taking,
condemnation or conveyance bears to the number of square feet of gross floor
area within the buildings comprising the Grand Rapids Plant prior to such
taking, condemnation or conveyance. To the extent that the award made for the
taking is available to Lessor, Lessor shall, at its own cost and expense, make
all necessary repairs or alterations to the Grand Rapids Plant so as to
constitute the portion of the Grand Rapids Plant not taken as a complete unit,
and Lessee shall have no obligation to make any such repairs or alterations.
Lessor shall be entitled to the entire award made for any taking, condemnation
or conveyance, except that Lessee shall not be precluded from pursuing any claim
directly against the condemning authority for its loss.


         14. Lessor's Right to Perform. Lessor may perform any obligations of
Lessee hereunder which Lessee has failed to perform. Lessee shall reimburse
Lessor for all payments made and expenses incurred. Such payments and expenses
shall be additional rent which is immediately due and payable, together with
interest thereon at the lesser of the rate of twelve percent (12%) per annum or
the highest legal rate of interest.


         15. Default. If default is made by Lessee in the payment of rent or
additional rent or in the performance of any of the conditions or covenants in
this Lease, and if such default shall continue for a period of ten (10) days
after written notice is given to Lessee by Lessor specifying the default, then
Lessor shall have the right to re-enter the Grand Rapids Plant and remove Lessee
and all persons therefrom and shall have the right to terminate this Lease. If
default is made by Lessee and Lessor exercises its option to terminate this
Lease, in addition to all other remedies now or hereafter provided to Lessor,
Lessor may proceed to re-rent the Grand Rapids Plant and collect from Lessee any
deficiency between the rent payable hereunder and the rent received from any
replacement tenant.

                  3. Maintenance. The proviso set forth in the initial sentence
of Paragraph 5 of the Lease shall be amended to read "provided, however, that
Lessor shall reimburse Lessee for the out-of-pocket cost in excess of $1,000 of
any single item of repair or replacement which was approved in advance by Lessor
(which approval shall not be unreasonably withheld) and was not the result of
the intentional act or negligence of Lessee, its employees, agents or invitees."

                  4. Construction of New Plant. A new Paragraph 17, with respect
to the construction of the New Plant, is added to the Lease, as follows:

         "17. Construction and Occupation of the New Plant.

                  (a) Lessor shall diligently proceed to have the New Plant
                  constructed by contractors and suppliers selected by it, in
                  accordance with Exhibit B attached hereto, and place the
                  heating and ventilation equipment in good working order as of
                  the date of delivery of possession to Lessee (hereinafter
                  sometimes referred to as "Lessor's Work"). All Lessor's Work
                  shall be fully inspected by Lessee and shall not carry any
                  warranty from Lessor whatsoever, whether express or implied.
                  However, Lessee shall have the right to claim directly against
                  Lessor's contractors and suppliers for the breach of their
                  warranties.

                  (b) Other than Lessor's Work, any alterations, improvements,
                  additions, physical changes or other work necessary or
                  desirable to place the New Plant in a condition suitable for
                  Lessee's business purposes ("Lessee's Work") shall be
                  performed in a good and workmanlike manner by and for Lessee
                  at Lessee's sole cost and expense on or before thirty (30)
                  days following the completion of Lessor's Work. No
                  construction or installation by Lessee shall begin until
                  Lessor has approved the plans therefor, which approval shall
                  not be unreasonably withheld or delayed.



                                      -3-
<PAGE>   12
                  All construction shall be performed in accordance with the
                  approved plans, at Lessee's sole cost and expense, by a
                  contractor or contractors first approved in writing by Lessor
                  (which approval shall not be unreasonably withheld or
                  delayed). Lessee's Work shall fully conform to all applicable
                  statutes, ordinances, regulations and codes. Prior to
                  commencing any work, Lessee shall require its contractors and
                  subcontractors to furnish Lessor with evidence of such
                  insurance coverage in such amounts as may be required by
                  Lessee.

                  (c) Upon the substantial completion of the Lessor's Work and
                  the Lessee's Work, the Lease term shall commence with respect
                  to the New Plant (the "New Plant Completion Date"). Once the
                  New Plant Completion Date has been determined, the parties
                  hereto agree to execute an addendum to this Lease setting
                  forth the actual New Plant Completion Date, the resultant
                  expiration date of this Lease, the square footage of the New
                  Plant, and the resultant rental rate payable with respect
                  thereto.

                  (d) The target New Plant Completion Date is April 1, 1989. If
                  possession of the New Plant shall for any reason not be
                  delivered to Lessee on such date, this Lease shall
                  nevertheless continue in full force and effect, and no
                  liability whatsoever shall arise against Lessor out of any
                  delay other than the abatement of rent, at the rate of
                  one-thirtieth (1/30th) of the monthly installment of rent for
                  the New Plant for each day of delay, until the Lessor's Work
                  and the Lessee's Work is completed.

                  (e) Lessor has entered into agreements, subject to customary
                  contingencies, for the construction of the New Plant and the
                  financing of such construction on terms satisfactory to
                  Lessor. Lessor shall comply with those agreements and exercise
                  every reasonable effort to obtain the construction and
                  financing of the New Plant in accordance with the terms of
                  those agreements. However, if Lessor is unable to do so for
                  any


                                      -4-
<PAGE>   13
                  cause beyond its reasonable control, Lessor may terminate this
                  Amendment by notice to Lessee and neither party shall have any
                  further liability hereunder.

                  5. Ratification. Except as expressly amended hereby, the Lease
shall continue in full force and effect, as written.

                  IN WITNESS WHEREOF, the parties hereto have executed this
Amendment to Lease as of the date first above written.

                               AMENDMENT TO LEASE



         THIS AMENDMENT TO LEASE ("Amendment") is made as of October 5, 1998, by
and between CARBONNEAU FAMILY LIMITED PARTNERSHIP, a Michigan limited
partnership, of 133 Robinhood Drive, S.E., Grand Rapids, Michigan 49546
("Lessor"), and ROCKFORD CORPORATION, an Arizona corporation, of 613 South
Rockford Drive, Tempe, Arizona 85281 ("Lessee") based on the following facts:

         A. Lessor's predecessor in title, Carbonneau Industries, Inc., and
Lessee, entered into a certain Lease Agreement dated October 27, 1986, effective
as of September 1, 1986 and amended as of October 1, 1988 (collectively,
"Lease") for the demise of certain premises commonly known as 609 Myrtle Street,
N.W., and 600 Webster, N.W., Grand Rapids, Michigan (collectively, "Grand Rapids
Plant").

         B. By its terms, the Lease is scheduled to terminate as of midnight,
March 31, 1999, which is ten years after the "New Plant Completion Date," as
defined in the Lease. However, Lessor and Lessee desire to extend the Lease
term, and provide Lessee with additional options to renew the Lease.

         C. To accomplish such purposes, Lessor and Lessee desire to amend the
Lease as provided in this Agreement.

         NOW, THEREFORE, Lessor and Lessee amend the Lease as follows:

         1. TERM. The fifth introductory paragraph of the Lease is amended in
part to provide that the Lease shall be "for a period commencing September 1,
1986, and ending march 31, 2001."

         2. RENT.

                  (a) Paragraph 2(j) of the Lease is amended in its entirety to
         substitute the following paragraphs:

                  (j-1) From September 1, 1998, through March 31, 1999, at the
         rate of $10,000 per month.

                  (j-2) From April 1, 1999, through March 31, 2001, at the rate
         of $11,000 per month.

                  (b) Paragraph 2(o) is amended in its entirety to substitute
         the following subparagraph:

                  (o) At the rate of $4.73 per square foot from April 1, 1997,
         through March 31, 2001.
<PAGE>   16
         3. RENEWAL OPTIONS. The following additional subparagraph is added to
Paragraph 16 of the Lease.

                  (j) Options to Renew. So long as Lessee is not then in default
         under this Lease, Lessee shall have three (3) options to renew this
         Lease for additional terms of one (1) year each, upon giving Lessor at
         least one hundred eighty (180) days written notice of the exercise of
         such option prior to the then scheduled termination date of the Lease.
         Each such renewal shall be on the same terms and conditions as set
         forth in this Lease, with the exception that the Rent payable under
         this Lease shall be increased at the commencement of each such renewal
         term by three percent (3%) over the Rent payable for the period
         immediately prior to such renewal.

         4. RATIFICATION. Except as expressly amended by this Amendment, the
Lease shall continue in full force and effect, as written.

         Lessor and Lessee have signed and delivered this Amendment to Lease as
of the date set forth above.

                                MANUFACTURING AND
                             DISTRIBUTION AGREEMENT


             This Agreement is between Rockford Corporation, an Arizona
corporation ("Rockford"), and Path Group Inc., an Arizona corporation ("Path").
Rockford and Path agree as follows:

1.       BACKGROUND.


         1.1      Rockford Business. Rockford is a manufacturer of high quality
                  consumer electronic products used in automotive, professional,
                  and home sound reproduction systems.

         1.2      Path Business and Experience. Path was formerly known as
                  "American Connection Incorporated," and is an affiliate of
                  Path Group PLC, a British corporation ("Path UK"). Path is a
                  successor to American Connection, Ltd., a British corporation
                  ("ACL"), and is a manufacturer and supplier of accessory
                  products that may be used in the installation of Rockford's
                  products and other company's products. All references to Path
                  in this Agreement include Path and ACL.

         1.3      Past Relationship. Rockford and Path are parties to agreements
                  relating to Rockford's distribution of Path products in
                  Europe, the United States, the Americas, and Asia as listed on
                  Exhibit D, Prior Agreements (the "Prior Agreements").

         1.4      New Relationship. Rockford and Path desire to renew and revise
                  their existing agreements relating to Rockford's distribution
                  of Path products. Under the new agreement, Path will
                  manufacture (or purchase) and warehouse accessory products
                  (the "Products"). Rockford will solicit sales of the Products
                  to Rockford's authorized dealers and distributors throughout
                  the world ("Dealers"). The Products covered by this Agreement
                  are identified on Exhibit A; the parties may at any time add
                  other products to those identified by amending Exhibit A and
                  the added products will then be treated for all purposes as
                  "Products."

         1.5      License. In connection with this Agreement, Rockford will
                  license Path to place certain Rockford trademarks and
                  tradenames (the "Names") on the Products, solely for sales of
                  the Products to Dealers. The Names are identified on Exhibit
                  B, which may be amended by the parties from time to time.

         1.6      Purpose. The purpose of this Agreement is to replace the Prior
                  Agreements. This Agreement states the terms of the agreement
                  between Path and Rockford relating to sales of the Products to
                  Rockford's Dealers.

2.       DISTRIBUTION OF THE PRODUCTS. Path will manufacture (or purchase) and
         warehouse the Products. Rockford will solicit sales of the Products
         and, upon receipt of orders, will ship the Products to Rockford's
         Dealers throughout the world. The parties will undertake these
         activities on the following basis:


         2.1      Inventory Locations. Path will manufacture or purchase the
                  Products and will maintain an inventory of the Products at its
                  own warehouses and at selected Rockford warehouse locations.
                  Path must insure the Products against casualty loss prior to
                  their shipment to Dealers.

                  (a)      Duty and Freight. Path is responsible for payment of
                           applicable duty and freight to deliver the Products
                           to each warehouse location.

                  (b)      Changes to Locations. Path is responsible for costs
                           and systems improvements at its own warehouse
                           locations and at Rockford's warehouse locations (to
                           the extent needed to keep Path inventory at such
                           locations), including equipment and license fees to
                           operate the locations. Rockford is not responsible
                           for any equipment or license fees related to any
                           changes to warehouse locations (including movements
                           into Rockford warehouses).

                  (c)      Europe and Singapore. In Europe and Singapore, Path
                           will own Products and locate them at Rockford's
                           warehouse in Germany and Singapore until their sale
                           to Dealers.

                  (d)      Germany. Path shall pay the value added tax (VAT)
                           upon entry of goods into the warehouse in Germany and
                           shall charge the VAT to Rockford on sales from the
                           warehouse in Germany.

         2.2      Inventory Levels. Path will maintain inventory at a level that
                  is sufficient to satisfy reasonably expected demand for the
                  Products.

                  (a)      Representatives of Rockford and Path will meet
                           regularly to discuss anticipated demand for the
                           Products and the level of inventory appropriate to
                           allow Rockford and Path to meet that demand.

                  (b)      Path is responsible for end-of-life ("EOL") inventory
                           management, including inventory levels and EOL
                           discounts. If Path wants to offer EOL discounts to
                           help manage inventory, Rockford will arrange to offer
                           the discounts to Dealers using free goods or other
                           means consistent with Rockford's sales practices for
                           its own products.

                  (c)      Upon termination of this Agreement, Rockford will in
                           good faith assist Path to liquidate Path's reasonable
                           inventory of the Products. These good faith efforts
                           will include Rockford's continued ordering of the
                           Products

                           from Path until the reasonable inventory of each
                           Product is exhausted, but only to the extent Rockford

                           the Products to Rockford's Dealers and will use the
                           sales methods it deems appropriate, which may (but

                           confirming to Rockford the quantities and dates of
                           shipment (including submission of entries to
                           Rockford's information systems) so that Rockford can
                           timely invoice its Dealers. Path will not make any
                           independent sales of the Products, but will:

                           (1)      assist Rockford's sales staff and sales

                           (2)      make available to Rockford's Dealers
                                    point-of-purchase materials, including
                                    product displays (subject to Rockford's
                                    approval and reasonable budgetary
                                    constraints established by Path); and

                           (3)      provide support as necessary in the form of
                                    technical information or advisory personnel.

                  (c)      Promotional Literature. Rockford is responsible for
                           development, production, and distribution of all
                           literature regarding the Products and for the cost
                           associated with exhibits, booths, and audio-visual
                           presentations at trade shows. Path is responsible for
                           development, production, and distribution of display
                           and point of sale materials for Dealer sites and
                           written material used for Dealer training. Rockford
                           and Path will consult with each other with respect to
                           the content and appearance of such materials.

                  (d)      Cooperation. Path will cooperate with Rockford's
                           efforts so that, for all purposes, Dealers are
                           encouraged to treat the Products as Rockford products
                           and to deal directly with Rockford on all matters
                           related to the Products.

                  receipt of orders for the Products. Rockford will promptly
                  give Path notice of the shipment of Products from Rockford's
                  warehouses.

         2.5      Price and Payment.

                  (a)      Price. After consultation with Rockford, Path will
                           establish Dealer Prices and suggested retail prices
                           for each Product in each region or territory.
                           Rockford will sell the Products at the applicable
                           Dealer Price, subject to reasonable payment, volume,
                           and other sales incentives that are consistent with
                           the incentives Rockford offers on its own products.

                  (b)      Payments by Dealers and Credit Risk. Rockford is
                           solely responsible for collecting amounts due for
                           sales of Products. Rockford is also responsible for
                           managing its credit relationship with its Dealers and
                           may establish, in connection with its acceptance of
                           orders and shipment of Products, reasonable credit
                           policies including, as it deems necessary,
                           requirements for COD sales only.

                  (c)      Payments by Rockford to Path. Path will submit
                           invoices to Rockford for all Products shipped in the
                           amounts established under Exhibit C. Rockford will
                           make payments in accordance with the terms set forth
                           on Exhibit C. All payments will be in U.S. Dollars at
                           the Path location designated by Path.

                  (d)      Returns. Rockford will accept returns of Products on
                           a basis consistent with Rockford's policies for
                           returns. Rockford will deliver returned Product to
                           Path and is entitled to a credit for the net amount
                           Rockford paid Path for the returned Product.

                  (e)      Discounts. (Confidential treatment has been requested
                           and redacted portions of this document have been
                           filed separately with the Commission.)

         2.6      Additional Names and Products. At its execution, this
                  Agreement covers only Products sold in connection with
                  Rockford's "Rockford-Fosgate" line of car audio products. The
                  parties are discussing an arrangement for sales of Products in
                  connection with Rockford's "Hafler" line of professional audio
                  products. If the parties agree on terms for such an
                  arrangement, they may execute a separate agreement covering
                  that arrangement or they may amend Exhibits A, B, and C to add
                  the Hafler related Products to this Agreement with appropriate
                  variations in the terms of those Exhibits.

3.       DEVELOPMENT AND ADDITION OF PRODUCTS.

         3.1      Development of Products. Rockford and Path will cooperate to
                  improve existing Products and develop new Products that will
                  satisfy the needs of Rockford's Dealers, and their customers.
                  Path is principally responsible for development of

                                     - 4 -

                  improvements to existing Products and new Products. Before the
                  development of new or improved Products the parties will meet
                  and agree upon:

                  (a)      the anticipated role of each party in development of
                           the Product;

                  (b)      any change in the marketing and administrative fees
                           or royalty necessary for the Product; and

                  (c)      ownership of patents, trade secrets, copyrights and
                           other intellectual property associated with the
                           Product (other than the Names, which will remain
                           Rockford's exclusive property).

         3.2      Addition of Products. Path will not produce or sell any
                  Products, and will not use the Names in connection with any
                  Products, until Rockford has approved such Products and added
                  them to Exhibit A as approved Products. When a Product is
                  approved and added to Exhibit A, Rockford and Path will also
                  agree whether the Product is to be "exclusive" under the terms
                  of this Agreement. Except as otherwise specifically agreed by
                  Rockford and Path, all Products will be exclusive.

         3.3      Deletion of Products. Rockford and Path will discontinue
                  Products as they reasonably determine is necessary because of
                  obsolescence, inadequate sales, or new product developments.

         3.4      Use of Products After Termination. Upon termination of this
                  Agreement, Path may manufacture, sell, and distribute
                  products, including tools, that were principally or
                  exclusively marketed through Rockford during the term of this
                  Agreement, except for products protected by Rockford patents
                  and products produced using Rockford's trade secrets,
                  confidential information, or other intellectual property. Path
                  may not use the Names in connection with any such products.
                  Path and its affiliates will own patents, trade secrets,
                  confidential information, and other intellectual property
                  associated with all Products Path or its affiliates develop
                  exclusively for Rockford. For example:

                  (a)      all tools and dies, sketches, designs, drawings,
                           forms, software, software manuals, source codes, and
                           other information and tangible property associated
                           with development of or manufacturing of the Products
                           Path or its affiliates develop exclusively for
                           Rockford will remain the property of Path unless Path
                           grants licenses or other rights to Rockford; and

                  (b)      the "Gamma Geometry" cable designed by Ixos (patents
                           applied for), which Path is licensed to manufacture
                           for certain Products, will remain the property of
                           Path's affiliate, Ixos, Ltd.

4.       USE OF NAMES.

                                     - 5 -

<PAGE>   6
         4.1      Limited License of Names. Rockford grants Path a right to use
                  the Names solely during the term of this Agreement and solely
                  in connection with sales of the Products to Rockford's
                  Dealers.

         4.2      Approval of Uses. Path will use the Names only in a manner and
                  form approved before use in writing by Rockford. If Path
                  wishes to propose a new use or form of the Names, it must
                  submit its proposal in writing to Rockford. Rockford will
                  promptly review the proposed use and indicate its approval or
                  disapproval in writing. Any proposed use will be deemed
                  approved if Rockford does not object within 30 business days
                  after Path submits it to Rockford in writing together with a
                  written request for approval.

         4.3      Quality of Products. Path will provide Rockford with initial
                  samples of each Product before any sale and Rockford must
                  approve the initial samples before any sale of a Product. Path
                  will provide Rockford with production samples from time to
                  time, as requested by Rockford, so that Rockford may confirm
                  that the Products conform to the approved samples and to
                  Rockford's requirements as to quality. All Products supplied
                  by Path will be of a quality at least equal to the initial
                  samples supplied to Rockford.

         4.4      Goodwill and Ownership of Names. All goodwill generated by the
                  use of the Names or promotion of the Products will accrue to
                  Rockford's benefit. Path disclaims any ownership rights in the
                  Names and goodwill of Rockford, acknowledges that the Names
                  are the sole and exclusive property of Rockford, and agrees
                  that it will not take any action challenging Rockford's
                  ownership and rights in the Names. Path will not (a) take any
                  action that would interfere with Rockford's use of the Names
                  or (b) file applications for registration of the Names
                  anywhere in the world.

         4.5      Infringements. If Path believes any other party is infringing
                  on Rockford's rights in the Names, then Path will promptly
                  notify Rockford and will cooperate with Rockford in any action
                  Rockford chooses to take to protect its rights in the Names.
                  Rockford will have sole and exclusive control of any actions
                  relating to such infringements.

         4.6      No Use after Termination. Upon expiration or termination of
                  this Agreement, Path will immediately cease using the Names
                  other than for sales permitted after termination under the
                  termination provisions of this Agreement.


5.       EXCLUSIVITY AND NON-COMPETE.

                  this Agreement:

                  (a)      Rockford will not sell (or license others to sell)
                           products that compete with the exclusive Products;
                           and

                  (b)      Neither Path nor any affiliate of Path will sell (or
                           license others to sell) products that compete with
                           the exclusive Products.

                  The parties may agree that a Product is exclusive only in part
                  of the world, in which case the restrictions in (a) and (b)
                  will apply only in the part of the world where the product is
                  exclusive.

         5.2      Non-Compete.  Neither Path nor its affiliates will:

                  (a)      during the term of this Agreement (and for one year
                           after its termination if termination is a result of
                           any breach by Path or a result of Path's election not
                           to renew this Agreement), either directly or through
                           any affiliate, offer for sale any products that are
                           competitive with an exclusive Product (for a Product
                           that is exclusive in only part of the world, this
                           restriction applies only in the part of the world
                           where the Product is exclusive); and

                  (b)      during or at any time after the term of this
                           Agreement, offer for sale any products using the
                           Names, or using names, marks, or other trade dress
                           that are confusingly similar to the Names, other than
                           Products sold under this Agreement.

6.       MANAGEMENT MEETINGS. Management of Rockford and Path will meet
         quarterly at Rockford's headquarters in Tempe, Arizona, to discuss the

                  their customers return Products requiring warranty service to
                  Rockford.

         7.2      Path Warranty and Service Procedures. Path warrants that the
                  Products will be free from defects in material and workmanship

                  will deliver Products requiring warranty service to Path, Path
                  will repair or exchange returned Products, and Path will
                  return the Products to Rockford's Dealers, or their customers,
                  at its sole expense.

         7.3      Encumbrances, Title, and Risk of Loss. Path warrants that the

                           Rockford will maintain product liability insurance
                           with insurers and in amounts reasonably satisfactory
                           to Path. Such insurance will name Path as an
                           additional insured on a form reasonably approved by
                           Path and will be cancelable by the insurer only after
                           30 days notice to Path.

                           will defend, indemnify and hold harmless Rockford,

                           from:

                           (1)      all Loss arising from or connected with the
                                    activities or operations of Path or its
                                    officers, directors, affiliates, employees,
                                    or agents; and

                           (2)      all Loss in product liability actions
                                    brought against Rockford involving the

                                    except that Path will have no obligation to
                                    defend, indemnify, or hold harmless from
                                    liability resulting from Rockford's acts or

                           insurers and in amounts reasonably satisfactory to
                           Rockford. Such insurance will name Rockford as an
                           additional insured on a form reasonably approved by
                           Rockford and will be cancelable by the insurer only

                           indemnified party learns of the claim. The
                           indemnifying party is entitled to assume the defense
                           of any claim and, if it does so, is not

                           defense of the claim and will not settle or
                           compromise any claim without the indemnifying party's
                           consent.

                  Agreement. If the Agreement is extended, the Agreement will

                  renew this Agreement each year for additional two year terms,
                  but only if both parties give written notice of renewal at
                  least 180 days before a scheduled expiration.

                  events:

                  (a)      If the other party breaches any material term of this

                           days after notice from the party;

                  (b)      If the other party suspends payment of its debts,
                           enters into or becomes subject to corporate
                           reorganization or rehabilitation procedures,
                           liquidation, dissolution, or bankruptcy proceedings,
                           or makes a composition with creditors, or makes an
                           assignment for the benefit of creditors, or seeks
                           relief under bankruptcy or other similar laws for
                           debtor's relief; or

                  (c)      If the performance of the Agreement by either party
                           is prevented by force majeure, and the condition
                           continues to prevent performance for 90 days.

         8.5      Specific Performance. In addition to its right to terminate,
                  Rockford has the right to obtain temporary and permanent
                  injunctive relief to prevent any breach or threatened breach
                  by Path or its affiliates of sections 4, 5 or 9 of this
                  Agreement. Path has the right to obtain temporary and
                  permanent injunctive relief to prevent any breach or
                  threatened breach by Rockford or its affiliates of sections 5
                  or 7 of this Agreement.

                  Agreement:

                  (a)      the parties will settle any amounts due between them
                           within 30 days;

                  (b)      Path will cease to make, use, or sell the Rockford
                           branded Products, except that Path may continue to
                           sell such Products pursuant to sales orders submitted
                           to it by Rockford on behalf of its Dealers. Path may
                           make such sales only out of inventory held by Path at
                           the time of termination or shipped to Path as a
                           result of orders outstanding at the time of
                           termination. Rockford will in good faith assist Path
                           to liquidate Path's reasonable inventory of the
                           Products. These good faith efforts will include
                           Rockford's continued ordering of the Products from
                           Path until the reasonable inventory of each Product
                           is exhausted, but only to the extent Rockford has
                           orders from Dealers for the Products;

                  (c)      Path will continue to honor warranty claims and
                           returns of Products sold by Rockford and delivered to
                           Rockford's Dealers and their customers; and

                  (d)      Path will maintain inventories of service parts for
                           the periods required by law.

                  Termination or expiration will not limit or exclude any and
                  all other rights of the parties (including rights to recover
                  damages, to offset damages against any amounts due, and to
                  equitable relief) and will not act as an election of remedies.

         consents to the jurisdiction of such courts for this purpose.


15.      WAIVER OF JURY TRIAL. Any dispute arising out of or in any way relating
         to this Agreement or the parties' relationship under this Agreement
         will be tried to the court, without a jury, and each party hereby
         irrevocably waives any right to request a jury trial in connection with
         such a dispute.


16.      DISCLAIMER OF DAMAGES. Path and Rockford irrevocably waive and
         relinquish any right to recover incidental, consequential, or punitive
         damages in any dispute arising out of or in any way relating to this
         Agreement or the parties' relationship under this Agreement.

         prevailing party is entitled to reasonable attorneys' fees, costs and

         prohibited by, or invalid under applicable law, or is inoperative for
         any reason, that provision will be deemed modified to the extent
         necessary to make it valid and operative, or if it cannot be so
         modified, then severed. The remainder of this Agreement will continue

         Americas, and Pacific Rim. This Agreement replaces and supercedes both
         of the earlier agreements, which are terminated when this Agreement is
         effective. Both parties acknowledge that this Agreement makes
         significant changes in the business arrangements relating to
         distribution of the Products.


21.      EXECUTION AND EFFECTIVE DATE. This Agreement is executed and accepted
         in Tempe, Arizona, on June 11, 1998, and is effective on July 1, 1998.

                               AMENDMENT AGREEMENT

                                       AND

                       AGREEMENT TO RENAME AS SENIOR NOTES

                                OCTOBER 28, 1994


Provident Mutual Life
            Insurance Company of Philadelphia
1600 Market Street
Philadelphia, PA.  19103


Ladies and Gentlemen:

                  The undersigned, Rockford Corporation, an Arizona corporation
(the "Company"), hereby agrees with you as follows:

         1.       AMENDMENT OF DEBENTURES AND REPLACEMENT WITH SENIOR NOTE.

                  1.1 Sale of Debentures by the Company. The Company issued and
sold to you (or your predecessor) as of January 12, 1988, $2,000,000 of its 10%
Convertible Subordinated Debentures (the "Debentures"), which had the terms and
granted to you the rights set forth in (1) the Convertible Subordinated
Debenture Purchase Agreement dated January 12, 1988 (the "Debenture Purchase
Agreement") and (2) the form of the Debentures.

                  1.2 Agreement to Amend. Subject to the terms and conditions of
this Agreement, and on the basis of the representations and warranties set forth
herein, you have agreed with the Company to amend the Debentures by renaming
them as Senior Notes (the "Senior Notes"), in principal amount equal to the
Debentures, bearing interest at the same rate as the Debentures, maturing at the
same time as the Debentures, and with amended terms as set forth in this
Agreement. The amendment is intended to effect the following substantive changes
to the Debentures:

                           (a)      Renaming to Senior Notes.  The Debentures
shall be renamed as "Senior Notes" in principal amount equal to the Debentures,
bearing interest at the same rate as the Debentures, maturing at the same time
as the Debentures, in the form of Exhibit A to this Agreement, and with amended
terms as set forth in this Agreement and in Exhibit A. The right of holders of
the Debentures to convert the Debentures into the Company's common stock shall
terminate and the Senior Notes shall not be convertible into other securities of
the Company.

                                     - 1 -
<PAGE>   2
                           (b)      Delivery of Warrants.  Upon renaming of the
Debentures as Senior Notes and termination of the conversion rights, the Company
shall deliver to each holder of the Senior Notes warrants (the "Warrants"),
detachable at any time at the election of the holder, which shall entitle the
holder to purchase shares of Company's Common Stock. The Warrants (1) shall be
in the form of Exhibit B to this Agreement; (2) shall require payment of $6.50
per share in cash upon exercise (subject to adjustment as set forth in the
Warrants); (3) shall expire if not exercised before the close of business on
February 3, 2000; and (4) shall be exercisable to purchase 167,400 shares, a
number of shares equal to the number of shares into which the Debentures could
have been converted on the date when they are renamed as Senior Notes and
amended.

The Warrants shall be treated for all purposes as if they had been issued when
the Debentures were issued and shall represent the same right to acquire shares
of common stock as were established in the Debentures. The intended substantive
effect of the renaming of the Debentures as Senior Notes, the amendment of the
Senior Notes, and the delivery of the Warrants is (i) to separate the right to
purchase the Company's common shares, currently attached to the Debentures, into
a security that may be separately held, (ii) to extend the period to exercise
the Warrants from the maturity date of the Debentures to February 3, 2000, and
(iii) to reduce the price of the common shares issuable upon exercise of the
Warrants from $11.9474 per share to $6.50 per share.

                           (a)      Replacement of Covenants.  The
representations and warranties, affirmative covenants, and other matters set
forth in the original Debenture Purchase Agreement shall be replaced by the
corresponding representations and warranties, affirmative covenants, and other
matters set forth in this Agreement. The new financial covenants are
substantially the same as the covenants established in the revolving credit
facility entered into between the Company and Norwest Business Credit, Inc.
("NBCI") as of May 1994. This replacement will allow the Company to operate on
financial covenants consistent with the Company's financial projections and will
supersede the existing debt covenants with which the Company is currently unable
to comply.

                  1.3      Closing of Amendment.

                           (a)      Offer to Holders.  In order to accept the
Amendment, you must deliver this Agreement, duly executed by you, to Company
along with the original Debenture held by you.

                           (b)      Closing Date.  The closing of this Agreement
(the "Closing") shall take place on the date when Company has received this
Agreement executed by you, the Debentures or such other hour and date as you and
the Company shall agree in writing (the "Closing Date"). On or as soon as
possible after the Closing Date, the Company shall deliver to you (i) a Senior
Note registered in your name in principal amount equal to the principal amount
of the Debenture surrendered and (ii) a Warrant exercisable for the
corresponding number of shares.

                                     - 2 -
<PAGE>   3
                           (c)      Effect of Closing.  As of the Closing Date,
the Debentures held by you shall be renamed for all purposes as the Senior
Notes, the Debentures and Debenture Purchase Agreement shall have no further
force or effect and shall be replaced, superseded, and amended in their entirety
by this Agreement, the Senior Notes, and the Warrants.

         2. REPRESENTATIONS AND WARRANTIES BY THE COMPANY. The Company
represents and warrants to you as follows:

                  2.1 Organization. The Company is a corporation duly organized,
validly existing and in good standing under the laws of the State of Arizona.
The Company has all requisite corporate power and authority to own, lease and
operate its properties and to carry on its business as now conducted and as
proposed to be conducted. On the Closing Date the Company will be duly qualified
or authorized to do business and in good standing in each jurisdiction where the
character of the property owned or leased or the nature of the business
transacted makes such qualification or authorization necessary.

                  2.2 Capitalization. The authorized and outstanding capital
stock of the Company, and the options, warrants, agreements or similar rights
granted by the Company for the issue or sale by it of any securities, is as set
forth on Exhibit C. All of the issued and outstanding shares of the Common Stock
of the Company have been duly authorized and are validly issued, fully paid and
nonassessable. The Company has reserved 167,400 shares of its Common Stock for
issuance upon exercise of the Warrants. All outstanding shares of the Common
Stock of the Company were issued in compliance with all applicable Federal and
state securities or "blue sky" laws. There are in existence or contemplated no
options, warrants, agreements or similar rights granted by the Company for the
issue or sale by it of any securities, other than the transactions contemplated
by this Agreement and the transactions disclosed in Exhibit C.

                  2.3 Financial Position. The Company's Balance Sheets as at
September 30, 1993 and Statements of Income and Retained Earnings and of changes
in Financial Position for its fiscal year then ended, as audited by Ernst &
Young and as set forth in Exhibit D, are true and correct in all material
respects as at such dates and for the periods then ended.

                  2.4 Duly Issued. The shares of the Common Stock issuable upon
exercise of the Warrants, upon such exercise and upon payment of the Warrant
Price provided therein, will be validly issued, fully paid and nonassessable.

                  2.5 Authorization. This Agreement has been duly authorized,
executed and delivered by and on behalf of the Company, and constitutes the
valid and binding agreement of the Company, enforceable in accordance with its
terms. The Company has full power and lawful authority (1) to amend the
Debentures and rename them as the Senior Notes, (2) to deliver the Warrants on
the terms and conditions set forth in this Agreement, and (3) to issue the
Common Stock issuable upon exercise of the Warrants.

                                     - 3 -
<PAGE>   4
                  2.6 Compliance with Laws. The Company is in compliance with
all laws, regulations and orders applicable to its business and properties, and
has all necessary permits and licenses.

                  2.7 Governmental Consents. Neither the execution and delivery
of this Agreement, nor the performance of the terms or consummation of the
transactions contemplated by the Company under this Agreement require any
consent, approval, authorization or other order of any court, regulatory body,
administrative agency or other governmental body, or any filings pursuant to the
Securities Act of 1933, as amended (the "Securities Act"), or the securities
laws of any state other than those obtained prior to and effective as of the
Closing Date. Neither the Company nor any agent acting on its behalf has
offered, or will offer, to sell (or has solicited or will solicit any offer to
buy) the Debentures, the Senior Notes, the Warrants, or any shares of the Common
Stock of the Company issuable upon the exercise of the Warrants, so as to
require the registration of any of such securities under the Securities Act
other than as contemplated by Article 4 of this Agreement. Based in part on your
representations which are set forth in Article 3 of this Agreement, the offer,
sale and issuance of the Debentures pursuant to the Debenture Purchase
Agreement, the renaming of the Debentures as Senior Notes and amendment of the
Senior Notes, the delivery of the Warrants, and the offer, sale and issuance of
shares of the Common Stock to be issued upon exercise of the Warrants are exempt
from the registration requirements of the Securities Act.

         3.       REPRESENTATIONS AND WARRANTIES OF PURCHASERS.

                  3.1 Investment Representation. You represent and warrant, and
in making the original sale to you of the Debentures, the renaming of the
Debentures as Senior Notes and amendment of the Senior Notes, and the delivery
to you of the Warrants it is specifically understood and agreed, that you
acquired the Debentures, that you agreed to the renaming and amendment of the
Senior Notes, that you are accepting the Warrants, and that you will (if you
choose to exercise the Warrants) acquire the shares of the Common Stock issuable
upon the exercise of the Warrants, for your own account and not with a view to
or for sale in connection with any distribution, and that you have no present
intention of distributing any of the same.

                  3.2 Stock Not Registered. You represent and acknowledge that
neither the Debentures, the Senior Notes, the Warrants, nor the shares of the
Common Stock issuable upon exercise of the Warrants have been registered under
the Securities Act or applicable state securities laws on the ground that the
original sale of the Debentures and the amendment, renaming, and delivery
provided for in this Agreement were and are exempt from registration under the
Securities Act. You acknowledge that the Company's reliance on such exemption is
predicated on your representations. You understand that the Senior Notes,
Warrants, and shares of Common Stock must be held indefinitely unless the offer
and sale are registered under the Securities Act and applicable state securities
laws or an exemption from registration is available. In particular, you are
aware that the Senior Note and Warrants, and any Common Stock issued on exercise
of the Warrants, may not be sold pursuant to Rule 144 promulgated under the
Securities Act unless all of the conditions of such rule are met. Among the
conditions for use of Rule 144 is the availability to the public of current
information about the Company. Such information is not now available and the
Company has no present plans to make such

                                     - 4 -
<PAGE>   5
information available. You represent that, in the absence of an effective
registration statement covering the Senior Notes, Warrants, or any Common Stock
issued on exercise of the Warrants, you will sell, transfer, or otherwise
dispose of the Senior Notes, Warrants, or any Common Stock issued on exercise of
the Warrants, only in a manner consistent with your representations and then
only in accordance with the provisions of Section 4.1 of this Agreement. You
further represent and acknowledge that any certificate representing the Senior
Notes, Warrants, or the shares of the Common Stock issuable upon exercise of the
Warrants, will bear the legend set forth in Section 4.2 and that the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
with respect to such shares or make appropriate notations to such effect in its
own stock transfer records. You further represent and acknowledge that any
certificate representing the Senior Notes, Warrants, or the shares of the Common
Stock issuable upon exercise of the Warrants, may bear any legends required by
applicable state securities laws.

                  3.3 Investment Experience Etc. You represent that you (1) have
such knowledge and experience in financial and business matters that you are
capable of evaluating the merits and risks of the purchase of the Debentures, of
their renaming as Senior Notes and amendment, and of the acceptance of the
Warrants, (2) have a net worth significantly in excess of the amount of your
investment in the Debentures and are able to bear the economic risk of the
purchase of the Debentures and of the holding of the Senior Notes and Warrants,
(3) have had access to information with respect to the Company necessary to
permit you to make an informed investment decision, and (4) are an "accredited
investor" as that term is defined in paragraph (a) of Rule 501 of Regulation D
promulgated under the Securities Act.

                  3.4 Organization Etc. You represent and warrant to the Company
that, on the date hereof and on the Closing Date, (1) if you are a corporation,
you are duly organized and validly existing under the laws of your state of
incorporation, you are and will be in good standing under such laws and you have
the requisite corporate power and authority to enter into this Agreement, (2) if
you are a general or limited partnership, you are and will be a general or
limited partnership duly organized and validly existing under the laws of your
state of formation, and you are and will be in good standing under such laws,
and you have and will have all requisite partnership power and authority to
enter into this Agreement, (3) this Agreement has been duly authorized, executed
and delivered by you to the Company, and (4) upon execution and delivery by the
Company, this Agreement constitutes your valid and binding agreement,
enforceable in accordance with its terms.

         4.       SECURITIES ACT AND RELATED MATTERS.

                  4.1 Transfer Restrictions. You agree that you will not offer
for sale, sell or transfer all or any part of the Senior Notes or Warrants, or
the shares of the Common Stock or other securities issuable upon exercise of the
Warrants, unless and until (1) the sale of such securities is registered under
the Securities Act and all other qualifications and proceedings under other
state or federal laws or regulations required in connection with such sale or
transfer have been obtained or taken or (2) such securities are sold or
transferred in accordance with an available exemption from registration or
qualification under the Securities Act and any applicable state securities or
"blue sky" laws and the Company has received an opinion of

                                     - 5 -
<PAGE>   6
counsel, which opinion and counsel shall each be reasonably satisfactory to the
Company, that registration is not required.

                  4.2 Legend on Certificate. Each certificate representing the
Senior Notes or Warrants, or any shares of the Common Stock or other securities
issued upon exercise of the Warrants, shall (unless in the opinion of counsel,
which opinion and counsel shall each be reasonably satisfactory to the Company,
the same is not necessary) bear a legend in substantially the following form:

                  "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
                  THE SECURITIES LAW OF ANY STATE. THE SECURITIES MAY NOT BE
                  SOLD, TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF
                  EFFECTIVE REGISTRATION STATEMENTS OR AN OPINION OF COUNSEL
                  ACCEPTABLE TO THIS COMPANY THAT REGISTRATION IS NOT REQUIRED."


Each certificate shall also bear any legends required by applicable state
securities laws. As used herein, "Restricted Security" means the Senior Notes
and Warrants, and shares of the Common Stock or other securities issued upon
exercise of the Warrants, and "Restricted Stock" means shares of Common Stock
issued upon exercise of the Warrants.

                  4.3 Registration Proposed by Company. If the Company proposes
to register any of its securities under the Securities Act (other than a
registration effected solely to implement an employee benefit plan or a
transaction to which Rule 145 under the Securities Act is applicable or a
registration using any form that does not permit secondary sales of securities)
it will give written notice to every holder of Warrants or Restricted Stock of
its intention to do so. Upon written request of any such holders delivered to
the Company within 30 days after receipt of such written notice (which request
shall state the number of shares of Restricted Stock to be registered and the
intended method of disposition) the Company will use its best efforts in
connection with such registrations of securities to be sold for the Company's
account, at its own expense to the extent provided in Section 4.5, to register
under the Securities Act all shares of Restricted Stock requested to be
registered by holders, all to the extent required to permit disposition in
accordance with the intended method. If such registration relates to an
underwritten public offering by the Company, only shares of Restricted Stock
which the requesting holders agree to include in the underwriting may be
included in the registration and, if the sole or managing underwriter of the
offering determines that the aggregate number of shares of Restricted Stock
requested to be included in the registration should be limited to a lesser
number due to market conditions or the necessity of including in such
underwriting and registration shares to be sold for the account of the Company,
then each holder who has requested that shares of Restricted Stock be included
in such underwriting and registration may sell only a pro rata portion of shares
of Restricted Stock.

                  4.4 Registration Requested by Purchasers. Upon written request
of the holder or holders of 50% of the Warrants then outstanding (or any
combination of the Warrants and of

                                     - 6 -
<PAGE>   7
Common Stock issued upon exercise of the Warrants which together, prior to such
conversion, would have constituted 50% of the Warrants) made at any time (a)
prior to the giving of written notice by the Company of its intention to
register any of its securities under the provisions of Section 4.3, which
registration becomes effective within six months following the giving of such
notice, and (b) after the later of (x) January 12, 1990 or (y) 12 months from
the effective date of any prior registration statement covering shares of the
Company's Common Stock, which request demands that the Company file a
registration statement under the Securities Act covering the registration of
Restricted Stock, the expected price to the public of which equals or exceeds
$7,500,000, then the Company will upon one occasion (l) promptly give written
notice of such proposed registration to every other holder of Restricted
Securities and (2) as expeditiously as possible and in any event within 90 days,
use its best efforts, at its own expense to the extent provided in Section 4.5,
to effect registration under the Securities Act of

                           (a) the sale of the Restricted Stock which the
                  Company has been requested to register pursuant to the written
                  request referred to above, and

                           (b) all other Restricted Stock the holders of which
                  shall make written request for registration to the Company,
                  such written request to be delivered to the Company within 30
                  days after the giving of the above written notice by the
                  Company,

all to the extent required to permit the disposition by the holders of the
securities so registered. The Company agrees that in-connection with effecting
any registration it will execute any required undertakings to file
post-effective amendments. The Company shall have no further obligations under
this Section 4.4 with respect to any subsequent registrations (1) after one
registration filed pursuant to any holder's request under this Section 4.4 (in
addition to any postponed registration as described below in this Section 4.4)
covering shares of Restricted Stock has become effective or (2) after you and
your permitted transferees hold, in the aggregate, an amount of the Warrants or
securities issued upon exercise of the Warrants, which constitute less than 10%
of the Warrants initially issued and sold pursuant to this Agreement.
Notwithstanding the foregoing if, within ten days following the receipt of the
request referred to in the first sentence of this Section 4.4, the Company shall
furnish to the requesting holder or holders a certificate stating that the
Company has determined to file within 60 days thereafter a registration
statement pertaining to an underwritten public offering of securities for the
account of the Company, then the Company shall not be obligated to effect a
registration pursuant to this Section 4.4 for a period of six months from the
date of such certificate, provided that the Company shall actively employ in
good faith all reasonable efforts to cause the registration statement for the
underwritten public offering to become effective as soon as reasonably
practicable. The Company shall not be entitled to delay the exercise of the
rights of the holders under this Section 4.4 by invoking the provisions of the
preceding sentence on more than one occasion.

                  4.5 Costs and Expenses. All costs and expenses in connection
with the registration of securities under Sections 4.3 and 4.4, including
Federal and state registration and filing fees, printing expenses (including the
number of preliminary and final prospectuses, post-effective amendments, and
supplements reasonably requested by the holders of Restricted

                                     - 7 -

Stock), and the fees and disbursements of counsel and of independent accountants
and other experts of the Company, shall be borne by the Company; provided,
however, that the Company shall not be obligated to pay underwriter's discounts
and commissions and fees and disbursements of counsel for the holders of
Restricted Stock. The Company will use its best efforts to keep effective any
registration for the period reasonably necessary to effect disposition in
accordance with the intended methods described in the requests for registration,
but if the Company is requested or required to maintain the registration
effective for more than six months, all out-of-pocket expenses of the Company
incurred in maintaining effectiveness after the initial six-month period shall
be borne by the holders of securities who have requested that effectiveness be
maintained in order to continue with the distribution, in such proportions as
they may agree upon.

                  4.6 Information. The holders of Restricted Stock covered by a
registration statement as provided in Sections 4.3 or 4.4 shall furnish in
writing to the Company such information regarding them, any Restricted Security
held by them, and the intended method of disposition of the Restricted Stock as
the Company shall reasonably request and as shall be required in connection with
the actions to be taken by the Company pursuant to Sections 4.3 or 4.4.

                  4.7 Blue Sky Registrations. In the case of any registration
under this Article 4 of any shares of Restricted Stock, the Company will use its
best efforts concurrently to register or qualify the same for sale under the
securities laws of those states in which registration or qualification is
required, except that the Company shall not be required to execute a general
consent to service or to qualify to do business in any state.

                  4.8 Lockup Agreement. In consideration for the Company
agreeing to its obligations under this Article 4, each holder of Restricted
Securities agrees that, in connection with any registration of the Company's
securities, upon the request of the underwriter(s) managing any underwritten
offering of the Company's securities, such holders shall execute an agreement
not to sell, make any short sale of, loan, grant any option for the purchase of,
or otherwise dispose of any Restricted Stock, other than shares included in the
registration, without the prior written consent of the underwriter(s) for the
period of time (not to exceed 90 days) from the effective date of the
registration as the underwriter(s) may specify.

                  4.9 Transferability. Provided that the requirements of Section
4.1 have been satisfied with respect to the sale or transfer of a Restricted
Security, any transferee shall be entitled to the rights and benefits of, and
shall be subject to the requirements of, Sections 4.2 through 4.8.

         5. COMPANY'S AFFIRMATIVE COVENANTS. The Company shall comply with the
following requirements unless holders of not less than 50% in principal amount
of the Senior Notes then outstanding agree otherwise in writing. These
requirements shall terminate upon the earlier of (1) the closing of an
underwritten public offering pursuant to an effective registration statement
under the Securities Act covering the offering and sale of Common Stock, or any
security convertible into Common Stock, (other than a registration under which
more than 25% of Restricted Stock is not registered) or (2) the date when less
than 25% of the Senior Notes

                                     WARRANT

                   TO PURCHASE UP TO 43 SHARES OF COMMON STOCK

             VOID AFTER 5:00 P.M., PHOENIX TIME, ON FEBRUARY 3, 2000


                              ROCKFORD CORPORATION

                           INCORPORATED UNDER THE LAWS
                             OF THE STATE OF ARIZONA

                  This certifies that, for value received, Ron Trout or the
registered holder hereof or assigns (the "Warrantholder") is entitled to
purchase from Rockford Corporation, an Arizona corporation (the "Company"), at
any time before 5:00 p.m., Phoenix time, on February 3, 2000, at the purchase
price per share of $ 6.50 (the "Warrant Price"), up to the number of shares of
Common Stock, no par value, of the Company set forth above (the "Shares"). The
number of Shares purchasable upon exercise of this Warrant and the Warrant Price
per share shall be subject to adjustment from time to time as set forth below.

                  1. Agreement. This Warrant was originally delivered pursuant
to the terms of the Convertible Subordinated Debenture Amendment Agreement and
Agreement to Rename as Senior Note between the Company and original
Warrantholder (the "Agreement"). In connection with the Agreement the Company
and the original Warrantholder agreed to (1) rename the Company's 10.5%
Convertible Subordinated Debentures due February 3, 1999 as the Company's
"Senior Notes due February 3, 1999" (the "Note") and (2) deliver the original of
this Warrant to purchase the Shares in order to separately evidence the right to
purchase the Shares (previously established in the Debentures) and amend the
terms for purchase of the Shares. This Warrant (i) evidences the right to
purchase the Shares, (ii) is issued under and in accordance with the Agreement,
(iii) is subject to the terms and provisions contained in the Agreement and the
Note, to all of which the Warrantholder by acceptance of this Warrant consents
and (iv) represents and evidences the same right to purchase the Shares
previously embodied in the Debentures (subject only to the changes set forth in
this Warrant or in the Agreement).

                                     - 7 -

Capitalized terms used in this Warrant shall have the meanings ascribed to them
in the Note or Agreement. This Warrant may be exercised at any time after its
issuance and before 5:00 p.m., Phoenix time, on February 3, 2000.

                  2. Detachment from Note. This Warrant is originally issued
together with the Note; however, it may be transferred independently of the Note
at any time, subject to compliance with the transfer restrictions set forth in
the Agreement.

                  3. Expiration. Unless earlier exercised or expired, this
Warrants shall expire at 5:00 p.m. Phoenix time on February 3, 2000.

                  4.       Exercise of Warrant.

                           Exercise.  This Warrant may be exercised in whole or
in part by presentation of this Warrant with the Exercise Form on the reverse
side hereof duly executed and simultaneous payment of the Warrant Price (subject
to adjustment) at the principal office of the Company. Payment of such price
shall be made at the option of the Warrantholder in certified funds or by wire
transfer.

                           Exercise Price and Fractional Shares.  This Warrant
is exercisable, at the option of the Warrantholder, to purchase shares of the
Company's Common Stock at the Warrant Price, subject to adjustment as provided
in this Warrant. The Company shall not be required to issue fractional shares of
Common Stock or other capital stock upon exercise of this Warrant and, in lieu
thereof, shall pay a cash adjustment based upon the then current fair market
value of the Common Stock as determined by the Board of Directors as at the last
business day prior to the date of exercise.

                           Adjustment Based Upon Stock Dividends, Combination of
Shares or Recapitalization. The Warrant Price and the number of Shares shall be
adjusted if the Company shall at any time after the original issuance of this
Warrant (i) pay a stock dividend on its Common Stock, (ii) subdivide its
outstanding shares of Common Stock into a greater number of shares, (iii)
combine its outstanding shares of Common Stock into a smaller number of shares,
(iv) issue by reclassification of its shares of Common Stock any other special
capital stock of the Company, or (v) distribute to all holders of Common Stock
evidences of indebtedness (including indebtedness convertible into Common Stock
or other securities of Company), securities (including common or preferred stock
of Company), or assets (excluding cash dividends) or rights or warrants to
subscribe for Common Stock or other securities of Company (other than those
mentioned above). Upon the occurrence of an event or events requiring adjustment
of the Warrant Price or an adjustment to the number of Shares or other
securities issuable upon exercise of this Warrant, and thereafter, the
Warrantholder upon exercise of this Warrant shall be entitled to receive the
number of shares of Common Stock or other securities of the Company which the
Warrantholder would have owned or have been entitled to receive after the
happening of any of the events described above had this Warrant been exercised
immediately prior to the happening of such event.

<PAGE>   25
                           Adjustment Based Upon Stock Issuances.  The Warrant
Price shall be adjusted if at any time after the original issuance of this
Warrant the Company issues, or issues rights or warrants to subscribe for or
purchase, Common Stock or securities convertible into or exchangeable for Common
Stock at less than the Warrant Price. Upon the occurrence of an event or events
requiring adjustment of the Warrant Price under this section the Warrant Price
shall be adjusted to be equal to the price of the new issue, and thereafter the
Warrantholder upon exercise of this Warrant shall be entitled to purchase the
Shares, or other securities of the Company which the Warrantholder is entitled
to receive, based upon the new Warrant Price per share.

                           Adjustment Based Upon Merger or Consolidation.  In
case of any consolidation or merger to which the Company is a party (other than
a merger in which the Company is the surviving entity and which does not result
in any reclassification of or change in the outstanding Common Stock of the
Company), or in case of any sale or conveyance to another person, firm, or
corporation of the property of the Company as an entirety or substantially as an
entirety, the Warrantholder shall have the right, upon exercise of this Warrant,
to receive the kind and amount of securities and property (including cash)
receivable upon such consolidation, merger, sale or conveyance by a holder of
the number of shares of Common Stock or other securities into which such Warrant
might have been converted immediately prior to the consolidation, merger, sale,
or conveyance.

                           No Adjustment for Outstanding Exercise and Option
Rights and Certain Other Securities. No adjustment of the Warrant Price or
number of shares issuable upon exercise shall be made upon the issuance by the
Company of (1) Common Stock upon conversion or exchange of securities
convertible or exchangeable into Common Stock and outstanding on or before
February 3, 1989, (2) Common Stock upon exercise of any employee's stock option
outstanding on or before February 3, 1989, or (3) Common Stock or securities
convertible into Common Stock, or options to purchase Common Stock not included
in (1) or (2) above and not amounting to more than 10% of the Company's fully
diluted Common Stock issue, pursuant to an employee benefit plan of the Company.

                  5. Corporate Status of Shares To Be Issued. All shares of the
Company's Common Stock (or other securities in the event of an adjustment of the
Warrant Price or number of shares issuable upon exercise) which may be issued
upon the exercise of this Warrant shall, upon issuance and payment of the
Warrant Price, be fully paid and nonassessable.

                  6. Issuance of Stock Certificate. Upon the exercise of this
Warrant, the Company shall forthwith issue to the Warrantholder a certificate or
certificates representing the number of shares of its Common Stock (or other
securities in the event of an adjustment of the Warrant Price or number of
shares issuable upon exercise) to which the Warrant relates.

                  7. Partial Exercise and Exchange. Upon any partial exercise of
this Warrant, there shall be signed and issued to the Warrantholder a new
Warrant in respect of the Shares as to which this Warrant shall not have been
exercised. This Warrant may be exchanged, at the office of the Company by
surrender of this Warrant properly endorsed for transfer, exercise, or exchange,
for one or more new Warrants for the same aggregate number of Shares as
evidenced by the Warrant or Warrants exchanged.

<PAGE>   26
                  8. Loss or Destruction of Warrant. The Company shall execute
and deliver a new Warrant of like tenor and date upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, of an indemnity by
the original Warrantholder, or, in case of any transfer, upon such terms as may
be satisfactory to the Company, or, in the case of mutilation, upon surrender
and cancellation of this Warrant.

                  9. Status of Holder of Warrant. This Warrant shall not entitle
the Warrantholder to any voting rights or other rights as a shareholder of the
Company, and no dividends shall be payable or accrue in respect of this Warrant
or the securities issuable upon exercise, unless and until this Warrant is
exercised. Upon the exercise of this Warrant, the Warrantholder shall, to the
extent permitted by law, be deemed to be the holder of record of the shares of
Common Stock or other securities issuable upon such exercise, notwithstanding
that the stock transfer books of the Company are then closed or that the
certificates representing such shares of Common Stock or other securities are
not then actually delivered.

                  10. Reservation of Shares. The Company shall reserve out of
its authorized shares of Common Stock (and other securities in the event of an
adjustment of the Warrant Price or number of shares issuable upon exercise) a
number of shares sufficient to enable it to comply with its obligation to issue
the Shares (and other securities in the event of an adjustment of the Warrant
Price or number of shares issuable upon exercise) upon the exercise of this
Warrant.

                  11.      Status Under Securities Laws.

                           No Registration.  This Warrant has not been, and the
securities issuable upon exercise hereof will not be, registered under the
Securities Act of 1933 (the "1933 Act"), the Arizona Securities Act (the
"Arizona Act") or the securities laws of any other jurisdiction and must be held
indefinitely without any transfer, sale or other disposition unless subsequently
registered under the 1933 Act, the Arizona Act and the securities laws of any
other applicable jurisdiction or, in the opinion of counsel acceptable to the
Company, registration is not required under such Acts or laws.

                           Legend.  There shall be endorsed on this Warrant and
on the certificates evidencing any securities issued upon the exercise of this
Warrant a legend substantially to the following effect:

                             "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE
                             NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
                             1933, AS AMENDED, OR THE SECURITIES LAW OF ANY
                             STATE. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED,
                             PLEDGED OR HYPOTHECATED (EXCEPT TO A COMMERCIAL
                             BANK OR OTHER CORPORATION AFFILIATED WITH SECURITY
                             PACIFIC BANK ARIZONA) IN THE ABSENCE OF EFFECTIVE
                             REGISTRATION STATEMENTS OR AN OPINION OF COUNSEL

                             REQUIRED."

Warrant and the Agreement, which contains additional provisions governing any
transfer of this Warrant. The Company may also refuse to effect a transfer,
sale, or other disposition of any Shares or other securities issued upon
exercise of this Warrant which would be in violation of any express prohibition
in this Warrant or in the Agreement.

                  13. Governing Law. This Warrant is delivered and is intended
to be performed in the State of Arizona and shall be construed and enforced in

                         Report of Independent Auditors

The Board of Directors and Stockholders
Rockford Corporation

We have audited the accompanying consolidated balance sheets of Rockford
Corporation and subsidiaries as of September 30, 1994 and 1993, and the related
consolidated statements of operations, stockholders' equity (deficit), and cash
flows for the years then ended. 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 audits 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, the financial statements referred to above present fairly, in
all material respects, the consolidated financial positions of Rockford
Corporation and subsidiaries at September 30, 1994 and 1993, and the
consolidated results of their operations and their cash flows for the years then
ended in conformity with generally accepted accounting principles.

1. ACCOUNTING POLICIES

ORGANIZATION AND DESCRIPTION OF BUSINESS

Rockford Corporation (Company) is presently engaged in the business of
manufacturing and distributing car audio electronics and speaker systems under
the division names of "Rockford Fosgate," "Rockford Acoustic Designs (formerly
Carbonneau)," "Hafler" and "Perfect Interface." The Company was organized and
incorporated under the laws of the State of Arizona on July 22, 1980, and has
manufacturing facilities in Tempe, Arizona and Grand Rapids, Michigan.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and
its wholly owned and majority owned subsidiaries in Germany and Japan.
Significant intercompany accounts and transactions have been eliminated in
consolidation.

RECEIVABLES

The Company sells its products principally to automotive stereo dealers
primarily in the United States, Europe and Asia. At September 30, 1994 and 1993,
net accounts receivable include approximately $475,000 and $247,000,
respectively, due from overseas businesses.

The Company also offers a prompt pay discount for certain invoices paid under 40
days of issuance and has included in its allowance for receivables at September
30, 1994 and 1993, approximately $180,000 with respect to accounts utilizing
such discounts after year-end.

INVENTORIES

Inventories consist principally of raw materials of electronic and mechanical
components used in the manufacturing of amplifier and speaker systems and
finished goods. Inventories are carried at the lower of cost or market using the
first-in, first-out (FIFO) method.

PROPERTY AND EQUIPMENT

Property and equipment is stated at cost. Depreciation and amortization are
computed principally on the straight-line method for financial reporting
purposes over a three to five year life.

1.  ACCOUNTING POLICIES (CONTINUED)

INCOME TAXES

The Company accounted for income taxes under the provisions of Accounting
Principles Board Opinion Number 11 through September 30, 1992. Statement of
Financial Accounting Standard No. 109, "Accounting for Income Taxes" was issued
by the Financial Accounting Standards Board in February 1992 and was adopted by
the Company as of October 1, 1992 (see Note 6).

RESEARCH AND DEVELOPMENT

During the years ended September 30, 1994 and 1993, research and development
expense of approximately $1,347,000 and $1,435,000, respectively, was charged to
expense as incurred.

FOREIGN CURRENCY TRANSLATION

The financial statements of foreign subsidiaries have been translated into U.S.
dollars in accordance with FASB Statement No. 52. All balance sheet accounts
have been translated using the current exchange rates at the balance sheet date.
Income statement amounts have been translated using the average exchange rate
for the year. The gains and losses resulting from the change in exchange rates
from year to year have been reported separately as a component of stockholders'
equity (deficit). The effect on the statement of operations of transaction gains
and losses is insignificant.

RECLASSIFICATIONS

Certain amounts in the 1993 financial statements have been changed to conform
them to the 1994 presentation.

6.  INCOME TAXES

Effective October 1, 1992, the Company changed its method of accounting for
income taxes from the deferred method too the liability method required by FASB
Statement No. 109, "Accounting for Income Taxes" (FAS 109). As permitted under
the new rules, prior years' financial statements have not been restated. The
cumulative effect of adopting FAS 109 as of October 1, 1992 was to increase the
net loss by $827,000.

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets as of September 30, 1994 are as follows:

</TABLE>

The valuation allowance decreased by $2,393,000 during 1994 based upon
management's assessment that a valuation allowance was no longer required with
the recent improvements in the Company's financial results. During 1993, the
valuation allowance was increased by $1,330,000 from the amount existing at
adoption based on that year's losses.

</TABLE>

The Company's effective tax rate differs from the statutory rates primarily due
to the noninclusion of foreign income and (losses) of approximately $223,000,
net, in 1994 and $(159,000), net, in 1993, utilization of net operating loss
carryforwards, as well as the deferred tax asset valuation allowance changes
during 1994 and 1993.

At September 30, 1994, the Company had a net operating loss carryforward of
approximately $3,950,000 for state income tax purposes which expires during 1996
through 1998.

7.  COMMON STOCK GRANTS AND OPTIONS

common stock grants as compensation and additional incentive to provide
continued services to the Company. The stock was granted at its fair market
value as determined by management at the date of the grant. If the officers' or
employees' employment with the Company is terminated during the four year
incentive period for any reason, the officer or employee shall be required to
forfeit all unvested stock issued under the stock grant program. The Company
charged to expense, under the stock grant program, $24,000 and $29,000 as
compensation in 1994 and 1993, respectively.

The Board of Directors of the Company granted a certain consulting firm, which
is providing executive and other consulting services to the Company, options to
purchase 50,000 shares of its authorized but unissued common stock at a price of
$23 per share (amended to $6.50 per share subsequent to year-end), protected
against dilution, as defined, and expiring in August 1999. The price per share
exceeded the fair market value at the date of the grant. These stock options
shall be contingent upon the Company's stock being publicly traded, or the
Company being

             Notes to Consolidated Financial Statements (continued)



7.  COMMON STOCK GRANTS AND OPTIONS (CONTINUED)

merged into or acquired by a private or publicly owned concern, and if such
event occurs, the stock options will vest 100 percent and shall be exercisable
only within 90 days after such event. The stock options shall vest 25 percent on
August 1, 1992, and 25 percent each year thereafter provided that the consulting
firm shall be, each vesting date, still performing the services required of
them.

Subsequent to year-end, the Board authorized the implementation of an incentive
stock option plan for certain employees. Under the plan, options to purchase
common stock of the Company will be granted to certain employees at the fair
market value of the underlying common stock. Up to 250,000 shares may be offered
under this plan.

8.  LIFE INSURANCE PROCEEDS

During 1993, the Company received proceeds of approximately $1,000,000 from a
claim filed under a key man life insurance policy due to the death of a member
of the Board of Directors. The proceeds are recorded in other income in the 1993
financial statements.

9.  CONTINGENCIES

The Company is a party to legal proceedings which arise out of the ordinary
course of business. Based upon advice from outside legal counsel, management is
of the opinion that these matters will have no material effect on the Company's
consolidated financial position.

10.  BENEFIT PLAN

During 1990, the Company's Board of Directors elected to establish the Rockford
Corporation 401(k) Retirement Savings Plan (Plan) covering substantially all
employees who have completed six consecutive months of service without regard to
hours of service. Under the terms of the Plan, employees may make voluntary
contributions, subject to Internal Revenue Service limitations. The company will
match employee contributions up to three percent of the employee's annual
compensation. Additional contributions to the Plan can be made at the discretion
of the Board of Directors. Contributions to the Plan during the years ended
September 30, 1994 and 1993 were approximately $140,000 and $71,000,
respectively.

2.       REPRESENTATIONS AND WARRANTIES BY THE COMPANY. The Company represents
         and warrants to you as follows:
<PAGE>   2
         2.1      Organization. The Company is a corporation duly organized,
                  validly existing and in good standing under the laws of
                  Arizona. The Company has all requisite corporate power and
                  authority to own, lease, and operate its properties and to
                  carry on its business as now conducted and as proposed to be
                  conducted. On the Closing Date the Company will be duly
                  qualified or authorized to do business and in good standing in
                  each jurisdiction where the character of the property owned or
                  leased or the nature of the business transacted makes such
                  qualification or authorization necessary. The Company has no
                  subsidiaries or any direct or indirect interest (by way of
                  stock ownership or otherwise) in any firm or business except
                  as disclosed in Schedule 2.1. The Company has furnished you
                  with certified copies of its Certificate of Incorporation and
                  By-Laws, as amended to the date hereof.

         2.2      Capitalization. The Company's authorized and outstanding
                  capital stock, and the outstanding securities convertible into
                  the Company's capital stock, is as set forth in Schedule 2.2.
                  All of the issued and outstanding shares of the Company's
                  Common Stock are duly authorized, validly issued, fully paid
                  and nonassessable. The Company has reserved the number of
                  shares of its Common Stock shown on Exhibit A for issuance
                  upon conversion of the Debentures. All outstanding shares of
                  the Common Stock of the Company were issued in compliance with
                  all applicable Federal and state securities or "blue sky"
                  laws. There are in existence or contemplated no options,
                  warrants, agreements or similar rights granted by the Company
                  for the issue or sale by it of any securities, other than the
                  transactions contemplated by this Agreement and the
                  transactions disclosed in Schedule 2.2.

         2.3      Financial Position. The Company's Balance Sheets as at
                  September 30, 1993 and 1994, and Statements of Income and
                  Retained Earnings and of changes in Financial Position for its
                  two fiscal years then ended, as audited by Ernst & Young LLP
                  and in the form set forth in Schedule 2.3, are true and
                  correct in all material respects as at such dates and for the
                  periods then ended.

         2.4      Duly Issued. The shares of the Common Stock issuable upon
                  conversion of the Debentures, upon such conversion, will be
                  validly issued, fully paid and nonassessable.

         2.5      Authorization. The Company has duly authorized, executed and
                  delivered this Agreement. This Agreement constitutes the valid
                  and binding agreement of the Company, enforceable in
                  accordance with its terms except as enforcement may be limited
                  by bankruptcy, insolvency, moratorium and equitable principles
                  applicable to creditors generally. The Company has full power
                  and lawful authority to issue and sell the Debentures on the
                  terms and conditions set forth in this Agreement and to issue
                  the Common Stock issuable upon conversion of the Debentures.

         2.6      Compliance with Laws. The Company is in compliance with all
                  laws, regulations and orders applicable to its business and
                  properties, and has all necessary permits and licenses.

         2.7      Governmental Consents. Neither the execution and delivery of
                  this Agreement, nor the performance of the terms or
                  consummation of the transactions contemplated by the Company
                  under this Agreement, require any consent, approval,
                  authorization, or other order of any court, regulatory body,
                  administrative agency, or other governmental body, or any
                  filings pursuant to the Securities Act of 1933, as amended
                  (the "Securities Act"), or the securities laws of any state
                  other than those obtained prior to and effective as of the
                  Closing Date. Neither the Company nor any agent acting on its
                  behalf has offered, or will offer, to sell (or has solicited
                  or will solicit any offer to buy) the Debentures or any shares
                  of the Common Stock of the Company issuable upon the
                  conversion of the Debentures so as to require the registration
                  of any of such securities under the Securities Act other than
                  as contemplated by Article 4 of this Agreement. Based in part
                  on your representations which are set forth in Article 3 of
                  this Agreement, the offer, sale, and issuance of the
                  Debentures pursuant to this Agreement and the shares of the
                  Common Stock of the Company to be issued upon conversion of
                  the Debentures are exempt from the registration requirements
                  of the Securities Act.

3.       REPRESENTATIONS AND WARRANTIES OF PURCHASERS. You represent and warrant
         to the Company and to the other purchasers of the Debentures:

         3.1      Investment Representation. You are acquiring the Debentures,
                  together with the shares of the Common Stock issuable upon the
                  conversion of the Debentures, for your own account and not
                  with a view to or for sale in connection with any
                  distribution. You have no present intention of distributing
                  the Debentures or the shares of the Common Stock issuable upon
                  the conversion of the Debentures.

         3.2      Stock Not Registered. You acknowledge that;

                  (a)      neither the Debentures nor the shares of the Common
                           Stock issuable upon conversion of the Debentures have
                           been registered under the Securities Act or
                           applicable state securities laws on the ground that
                           the issuance to you is exempt from registration under
                           the Securities Act;

                  (b)      the Company's reliance on such exemption is
                           predicated on your representations;

                  (c)      the Debentures and shares of Common Stock must be
                           held indefinitely unless the offer and sale are
                           registered under the Securities Act, and applicable
                           state securities laws, or an exemption from
                           registration is available. In particular, you
                           acknowledge that the Debentures, and any Common Stock
                           issued on conversion, may not be sold pursuant to
                           Rule 144 promulgated under the Securities Act unless
                           all of the conditions of such rule are met. Among the
                           conditions for use of Rule 144 is the availability to
                           the public of current information about the Company.
                           Such information is not now available and the Company
                           has no present plans to make such information
                           available;

                  (d)      in the absence of an effective registration statement
                           covering the Debentures, or any Common Stock issued
                           on conversion thereof, you will sell, transfer, or
                           otherwise dispose of the Debentures, or any Common
                           Stock issued on conversion, only in a manner
                           consistent with your representations and then only in

                           or make appropriate notations to such effect in its
                           own stock transfer records; and

                           shares of the Common Stock issuable upon conversion
                           of the Debentures, may bear any legends required by
                           applicable state securities laws.

4.       SECURITIES ACT AND RELATED MATTERS.

         4.1      Transfer Restrictions. You will not offer for sale, sell or
                  transfer all or any part of the Debentures, or the shares of
                  the Common Stock or other securities into which the Debentures
                  are convertible, unless (1) the sale is registered under the
                  Securities Act, and all other qualifications and proceedings
                  required under other


                                      -4-
<PAGE>   5
                  state or federal laws or regulations have been obtained or
                  taken, or (2) an exemption from registration or qualification
                  under the Securities Act and any applicable state securities
                  or "blue sky" laws is available and the Company has received
                  an opinion of counsel reasonably satisfactory to the Company
                  that registration is not required.

         4.2      Legend on Certificate. Each certificate representing the
                  Debentures, or any shares of the Common Stock or other
                  securities issued upon conversion of the Debentures, will bear
                  a legend in substantially the following form (unless the
                  Company has received in the opinion of counsel reasonably
                  satisfactory to the Company that a legend is not necessary):

                           "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE
                           NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
                           AS AMENDED, OR THE SECURITIES LAW OF ANY STATE. THE
                           SECURITIES MAY NOT BE SOLD, TRANSFERRED, PLEDGED OR
                           HYPOTHECATED IN THE ABSENCE OF EFFECTIVE REGISTRATION
                           STATEMENTS OR AN OPINION OF COUNSEL ACCEPTABLE TO
                           THIS COMPANY THAT REGISTRATION IS NOT REQUIRED."

                  Each certificate will also bear any legends required by
                  applicable state securities laws. In this Agreement
                  "Restricted Security" means the Debentures and shares of the
                  Common Stock or other securities issued upon conversion of the
                  Debentures and represented by certificates bearing the legend
                  set forth in this Section 4.2 and "Restricted Stock" means
                  shares of Common Stock issued upon conversion of the
                  Debentures and represented by certificates bearing the legend
                  set forth in this Section 4.2.

         4.3      Registration Proposed by Company.

                  (a)      Notice of Registration. If the Company proposes to
                           register any of its securities under the Securities
                           Act it will give written notice to every holder of a
                           Restricted Security except that the Company need not
                           give notice of (1) a registration solely to implement
                           an employee benefit plan, (2) a transaction to which
                           Rule 145 under the Securities Act is applicable, or
                           (3) a registration using any form that does not
                           permit secondary sales of securities.

                  (b)      Participation by Holders. If any holder of a
                           Restricted Security delivers to the Company, within
                           30 days of the Company's notice to the holders, a
                           notice stating the number of shares of Restricted
                           Stock to be registered and the intended method of
                           disposition, the Company will use its best efforts to
                           register under the Securities Act the shares of
                           Restricted Stock requested to be registered (1) in
                           connection with the registrations of securities to be
                           sold for the Company's account, (2) at its own
                           expense to


                                      -5-
<PAGE>   6
                           the extent provided in Section 4.5, and (3) to the
                           extent required to permit disposition in accordance
                           with the intended method.

                 (c)       Limitations on Company's Obligation. If the Company's
                           proposed registration relates to an underwritten
                           public offering by the Company, the Company is not
                           required to register shares of Restricted Stock
                           unless the requesting holders agree to include them
                           in the underwriting. If the sole or managing
                           underwriter of the offering determines that the
                           aggregate number of shares of Restricted Stock
                           included in the registration should be limited due to
                           market conditions or the necessity of including
                           shares to be sold for the account of the Company,
                           then each holder who has requested that shares of
                           Restricted Stock be included may sell only a prorata
                           portion of shares of Restricted Stock.

         4.4      Registration Requested by Purchasers.

                  (a)       Request for Registration. The holder or holders of
                            50% of the Restricted Securities may request that
                            the Company register Restricted Stock at any time
                            (1) before the Company gives written notice of its
                            intention to register its securities under Section
                            4.3 (but only if the registration becomes effective
                            within six months after the Company gives the
                            notice) and (2) after the later of (i) May ___, 1997
                            or (ii) 12 months after the effective date of any
                            prior registration statement covering shares of the
                            Company's stock. In determining whether 50% of the
                            holders of Restricted Securities have made a
                            request, Restricted Stock and other securities
                            issued upon conversion of the Debentures will be
                            counted on the basis of the amount of Debentures
                            from which they were converted.

                   (b)      Content of Request. The request must state the
                            number of shares of Restricted Stock to be
                            registered and the intended method of disposition.
                            The Company is not obligated to file a registration
                            statement if the expected price to the public of the
                            offering of Restricted Stock is less than
                            $15,000,000.

                   (c)      Required Registration. Upon receipt of a request
                            that satisfies the requirements stated above, the
                            Company will upon one occasion (1) promptly give
                            written notice of the proposed registration to every
                            other holder of Restricted Securities and (2) as
                            expeditiously as possible (and in any event within
                            90 days) use its best efforts, at its own expense to
                            the extent provided in Section 4.5, to effect
                            registration under the Securities Act of

                           (i)      the sale of the Restricted Stock which is
                                    the subject of the written request referred
                                    to above, and


                                      -6-
<PAGE>   7
                           (ii)     all other Restricted Stock whose holders
                                    make written request for registration to the
                                    Company within 30 days after the Company
                                    gives them notice of the proposed
                                    registration

                  all to the extent required to permit the disposition by the
                  holders of the securities so registered. In connection with
                  any registration, the Company will execute any required
                  undertakings to file post-effective amendments.

                  (d)      Limitations on Company's Obligation. The Company is
                           not obligated under this Section 4.4 after (1) one
                           registration, filed pursuant to any holder's request
                           under this Section 4.4 (other than a delayed
                           registration as described below), has become
                           effective or (2) you and your permitted transferees
                           hold less than 10% of the Restricted Securities
                           initially issued and sold pursuant to this Agreement.

                  (e)      Delay of Registration. If, within ten days after the
                           Company receives a request for registration under
                           subsection (a), the Company furnishes a certificate
                           stating that the Company intends to file within 60
                           days a registration statement for an underwritten
                           public offering of securities for the Company's
                           account, then the Company is not obligated to file a
                           registration under this Section 4.4 for six months
                           from the date of the Company's certificate. The
                           Company must make all reasonable efforts to cause the
                           registration statement for the underwritten public
                           offering to become effective as soon as reasonably
                           practicable. The Company may invoke this subsection,
                           and delay a registration requested under Section 4.4,
                           only one time.

         4.5      Costs and Expenses. The Company will pay all its costs and
                  expenses in connection with a registration of securities under
                  Sections 4.3 or 4.4, including Federal and state registration
                  and filing fees, printing expenses (including a reasonable
                  number of preliminary and final prospectuses, post-effective
                  amendments, and supplements requested by the holders of
                  Restricted Stock), and the fees and disbursements of counsel,
                  independent accountants, and other experts of the Company. The
                  Company will not pay underwriter's discounts and commissions
                  or the fees and disbursements of counsel, independent
                  accountants, or other experts of the holders of Restricted
                  Stock. The Company will use its best efforts to keep effective
                  any registration for the period reasonably necessary to effect
                  disposition in accordance with the intended methods described
                  in the requests for registration. If the Company is requested
                  or required to maintain the registration effective for more
                  than six months the holders of securities who have requested
                  that effectiveness be maintained, in order to continue with
                  the distribution, will pay (in such proportions as they may
                  agree upon) all out-of-pocket expenses of the Company incurred
                  in maintaining effectiveness after the initial six-month
                  period.

         4.6      Information. The holders of Restricted Stock covered by a
                  registration statement under Sections 4.3 or 4.4 will furnish
                  to the Company (in writing) any


                                      -7-
<PAGE>   8
                  information regarding them, Restricted Securities held by
                  them, and the intended method of disposition of the Restricted
                  Stock as the Company reasonably requests or as is required in
                  connection with the registrations under Sections 4.3 or 4.4.

         4.7      Blue Sky Registrations. In any registration under this Section
                  4, the Company will use its best efforts to register or
                  qualify the Restricted Stock for sale under the securities
                  laws of those states in which registration or qualification is
                  required, except that the Company is not required (a) to
                  execute a general consent to service or (b) to qualify to do
                  business in any state.

         4.8      Lockup Agreement. In connection with any registration of the
                  Company's securities, upon request of the underwriters
                  managing the offering, each holder of Restricted Securities
                  will execute an agreement not to sell, make a short sale of,
                  loan, grant an option for the purchase of, or otherwise
                  dispose of any Restricted Stock (other than shares included in
                  the registration or shares sold with the underwriters' prior
                  written consent) for up to 90 days after the effective date of
                  the registration.

         4.9      Transferability. If the requirements of Section 4.1 have been
                  satisfied for the sale or transfer of a Restricted Security,
                  the transferee will be entitled to the rights and benefits of,
                  and will be subject to the requirements of, Sections 4.1
                  through 4.8.

5.       COMPANY'S AFFIRMATIVE COVENANTS. The Company will comply with the
         following requirements unless holders of more than 50% of the
         outstanding Restricted Securities agree otherwise in writing. These
         requirements will terminate upon the earlier of (1) the closing date of
         an underwritten public offering of the Company's common stock pursuant
         to an effective registration statement under the Securities Act or (2)
         the date when less than 25% of the Restricted Securities are held by
         the original holders of the Debentures or their permitted transferees.
         These requirements may be amended by a written agreement between the
         Company and holders of more than 50% of the outstanding Restricted
         Securities. The financial covenants below are substantially the same as
         the covenants established in the revolving credit facility entered into
         between the Company and Norwest Business Credit, Inc. ("NBCI") as of
         May 1994; you agree that, upon any revision or refinancing of the
         Company's principal credit facility it is your intention to consent to
         the amendment of the financial covenants in this Agreement so that they
         are consistent with the terms of the new or revised credit facility.

         5.1      Reporting Requirements. The Company will deliver to you each
                  of the following:

                  (a)      Annual Financial Statements. No later than 90 days
                           after the end of each Company fiscal year, audited

                           (1)      the Company's balance sheet as at the end of
                                    the fiscal year, and

                           amounts will be paid before the date when penalties
                           attach thereto,

                  discontinuing the operation and maintenance of any of its
                  properties if such discontinuance is in its judgment
                  desirable.

                  risks as is usually carried by companies engaged in similar
                  business and owning similar properties in the same general
                  areas in which the Company operates.

         5.7      Preservation of Corporate Existence. The Company will preserve
                  and maintain its corporate existence and all rights,
                  privileges, and franchises necessary or desirable in the
                  conduct of its business. The Company will conduct its business

                  rate for federal and state income tax purposes (after taking

                  calculating the federal income tax liability and for the state
                  or states in which each shareholder is liable for income

                  traded and whose stock trades at a bid or closing price at
                  least equal to one hundred fifty percent (150%) of the then

                  unless, in each case, by the terms of the instrument creating
                  or evidencing the indebtedness it is expressly provided that
                  such indebtedness is not superior in right of payment to this
                  Debenture.

                  to adjustment as provided in this Debenture (the "Conversion
                  Price"). The Company is not required to issue fractional
                  shares of Common Stock or other capital stock upon conversion
                  of this Debenture and, in lieu thereof, will pay a cash
                  adjustment based upon the then current fair market


                                      -3-

                  value of the Common Stock as determined by the Board of
                  Directors on the last business day before the date of
                  conversion.

         6.2      Adjustment Based Upon Stock Dividends Combination of Shares or
                  Recapitalization. The Conversion Price and the number of
                  Shares will be adjusted if the Company, at any time after the
                  original issuance of this Debenture,

                  (a)      pays a stock dividend on its Common Stock,

                  (b)      subdivides its outstanding shares of Common Stock
                           into a greater number of shares,

                  (c)      combines its outstanding shares of Common Stock into
                           a smaller number of shares,

                  (d)      issues by reclassification of its shares of Common
                           Stock any other special capital stock of the Company,
                           or

                  (e)      distributes to all holders of its Common Stock
                           evidences of indebtedness or assets (excluding cash
                           dividends) or rights or warrants to subscribe for
                           Common Stock (other than those mentioned above).

                  On or after the occurrence of an event or events requiring
                  adjustment of the Conversion Price, the Holder upon surrender
                  of this Debenture for conversion will be entitled to receive
                  the number of shares of Common Stock or other securities of
                  the Company which the Holder would have owned or been entitled
                  to receive had this Debenture been converted immediately
                  before the happening of the event requiring adjustment of the
                  Conversion Price.

         6.3      Adjustment Based Upon Stock Issuances. The Conversion Price
                  will be adjusted if, at any time after the original issuance
                  of this Debenture, the Company issues Common Stock, issues
                  rights or warrants to subscribe for or purchase Common Stock,
                  or issues securities convertible into or exchangeable for
                  Common Stock at less than the Conversion Price. Upon the
                  occurrence of an event or events requiring adjustment of the
                  Conversion Price under this section the Conversion Price will
                  be adjusted to be equal to the price of the new issue. An
                  adjustment under this section will not increase the number of
                  shares of Common Stock, or other securities, which the Holder
                  will be entitled to receive upon surrender of this Debenture
                  for conversion, but will only reduce the Conversion Price
                  which the Holder must pay to acquire such Common Stock or
                  other securities. Any amount of this Debenture not required to
                  be used in a conversion, because of an adjustment of the
                  Conversion Price under this section, must be paid by the
                  Company to the Holder upon any redemption or upon maturity of
                  this Debenture.

         6.4      Adjustment Based Upon Merger or Consolidation. In case of any
                  consolidation or merger to which the Company is a party (other
                  than a merger in which the Company is the surviving entity and
                  which does not result in any reclassification


                                      -4-
<PAGE>   21
                  of or change in the outstanding Common Stock of the Company)
                  or in case of any sale or conveyance to another person, firm,
                  or corporation of the property of the Company as an entirety
                  or substantially as an entirety, the Holder will have the
                  continuing right to convert this Debenture into the kind and
                  amount of securities and property (including cash) receivable
                  upon such consolidation, merger, sale, or conveyance by a
                  holder of the number of shares of Common Stock into which this
                  Debenture might have been converted immediately before the
                  consolidation, merger, sale, or conveyance.

         6.5      No Adjustment for Outstanding Conversion and Option Rights and
                  Certain Other Securities. Notwithstanding any other section of
                  this Agreement, no adjustment of the Conversion Price will be
                  made upon the issuance by the Company of

                  (a)      Common Stock upon conversion or exchange of
                           securities convertible or exchangeable into Common
                           Stock and outstanding on or before the date of this
                           Debenture,

                  (b)      Common Stock upon exercise of any employee's stock
                           option outstanding on or before the date of this
                           Debenture, or

                  (c)      Common Stock or securities convertible into Common
                           Stock, not amounting to more than 10% of the
                           Company's issued and outstanding Common Stock, issued
                           after the date of this Debenture pursuant to an
                           employee benefit plan of the Company.

         6.6      Exercise of Conversion Privilege. The Conversion Privilege is
                  exercisable by the Holder upon written notice to the Company
                  (or its successor) and the surrender of this Debenture in
                  exchange for the number of shares of Common Stock (or other
                  securities and property, including cash, in the event of an
                  adjustment of the Conversion Price) into which this Debenture
                  is convertible based upon the Conversion Price. Conversion
                  rights will expire at the close of business on the business
                  day before the maturity or redemption date.

7.       CORPORATE STATUS OF SHARES TO BE ISSUED. All shares of the Company's
         Common Stock (or other securities in the event of an adjustment of the
         Conversion Price) issued upon the conversion of this Debenture will,
         upon issuance, be fully paid and nonassessable.

8.       ISSUANCE OF STOCK CERTIFICATE. Upon conversion of this Debenture, the
         Company will forthwith issue to the Holder a certificate or
         certificates representing the number of shares of its Common Stock (or
         other securities in the event of an adjustment of the Conversion Price)
         to which the conversion relates.

9.       STATUS OF HOLDER OF DEBENTURE. This Debenture does not entitle the
         Holder to any voting rights or other rights as a shareholder of the
         Company. No dividends are payable or accrue in respect of this
         Debenture, or the securities issuable upon conversion, unless and until
         this Debenture is converted. Upon the conversion of this Debenture, the
         Holder will (to the extent permitted by law) be deemed to be the holder
         of record of the shares of


                                      -5-
<PAGE>   22
         Common Stock issuable upon conversion, notwithstanding that the stock
         transfer books of the Company are then closed or that the certificates
         representing the shares of Common Stock are not then actually
         delivered.

10.      LOSS OR DESTRUCTION OF DEBENTURE. The Company will execute and deliver
         a new debenture of like tenor and date upon receipt by the Company of
         evidence satisfactory to it of the loss, theft, destruction, or
         mutilation of this Debenture and (a) in the case of loss, theft, or
         destruction, of an indemnity by the Holder, (b) in case of any
         transfer, upon such terms as are satisfactory to the Company, or (c) in
         the case of mutilation, upon surrender and cancellation of this
         Debenture.

11.      RESERVATION OF SHARES. The Company will reserve out of its authorized
         shares of Common Stock (and other securities in the event of an
         adjustment of the Conversion Price) a number of shares sufficient to
         enable it to comply with its obligation to issue shares of Common Stock
         (and other securities in the event of an adjustment of the Conversion
         Price) upon the conversion of this Debenture.

12.      STATUS UNDER SECURITIES LAWS.

         12.1     No Registration. This Debenture has not been, and the
                  securities issuable upon conversion hereof will not be,

                  the Arizona Securities Act (the "Arizona Act") or the
                  securities laws of any other jurisdiction. This Debenture, and
                  such securities, must be held indefinitely without any
                  transfer, sale, or other disposition unless (a) subsequently
                  registered under the 1933 Act, the Arizona Act and the
                  securities laws of any other applicable jurisdiction or (b) in
                  the opinion of counsel acceptable to the Company, registration
                  is not required under such Acts or laws.

         12.2     Legend. There will be endorsed on this Debenture, and on the
                  certificates evidencing any securities issued upon the
                  conversion of this Debenture, a legend substantially to the
                  following effect:


                           "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE
                           NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
                           AS AMENDED, OR THE SECURITIES LAW OF ANY STATE. THE
                           SECURITIES MAY NOT BE SOLD, TRANSFERRED, PLEDGED OR
                           HYPOTHECATED IN THE ABSENCE OF EFFECTIVE REGISTRATION
                           STATEMENTS OR AN OPINION OF COUNSEL ACCEPTABLE TO
                           THIS COMPANY THAT REGISTRATION IS NOT REQUIRED."

         12.3     Restriction on Other Securities. Except in certain limited
                  circumstances, the restrictions on the transfer of this
                  Debenture will also apply to (a) securities issued upon
                  conversion of this Debenture and (b) shares of capital stock
                  or other securities issued or otherwise acquired on account of
                  the Debenture (or securities issued upon conversion of the
                  Debenture) including, without limitation, shares


                                      -6-
<PAGE>   23
                  and securities issued or acquired as a result of a stock
                  dividend, stock split or exchange, or any distribution of
                  shares or securities pursuant to any corporate reorganization,
                  reclassification, or similar event.

         12.4     Refusal to Transfer. The Company may refuse to effect a
                  transfer, sale or other disposition of this Debenture, or the
                  shares issuable upon conversion, by the Holder or its
                  successors or assigns otherwise than as expressly permitted by
                  this Debenture.

                         Report of Independent Auditors

The Board of Directors and Stockholders
Rockford Corporation

We have audited the accompanying consolidated balance sheets of Rockford
Corporation and subsidiaries as of September 30, 1994 and 1993, and the related
consolidated statements of operations, stockholders' equity (deficit), and cash
flows for the years then ended. 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 audits 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, the financial statements referred to above present fairly, in
all material respects, the consolidated financial positions of Rockford
Corporation and subsidiaries at September 30, 1994 and 1993, and the
consolidated results of their operations and their cash flows for the years then
ended in conformity with generally accepted accounting principles.

1. ACCOUNTING POLICIES

ORGANIZATION AND DESCRIPTION OF BUSINESS

Rockford Corporation (Company) is presently engaged in the business of
manufacturing and distributing car audio electronics and speaker systems under
the division names of "Rockford Fosgate," "Rockford Acoustic Designs (formerly
Carbonneau)," "Hafler" and "Perfect Interface." The Company was organized and
incorporated under the laws of the State of Arizona on July 22, 1980, and has
manufacturing facilities in Tempe, Arizona and Grand Rapids, Michigan.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and
its wholly owned and majority owned subsidiaries in Germany and Japan.
Significant intercompany accounts and transactions have been eliminated in
consolidation.

RECEIVABLES

The Company sells its products principally to automotive stereo dealers
primarily in the United States, Europe and Asia. At September 30, 1994 and 1993,
net accounts receivable include approximately $475,000 and $247,000,
respectively, due from overseas businesses.

The Company also offers a prompt pay discount for certain invoices paid under 40
days of issuance and has included in its allowance for receivables at September
30, 1994 and 1993, approximately $180,000 with respect to accounts utilizing
such discounts after year-end.

INVENTORIES

Inventories consist principally of raw materials of electronic and mechanical
components used in the manufacturing of amplifier and speaker systems and
finished goods. Inventories are carried at the lower of cost or market using the
first-in, first-out (FIFO) method.

PROPERTY AND EQUIPMENT

Property and equipment is stated at cost. Depreciation and amortization are
computed principally on the straight-line method for financial reporting
purposes over a three to five year life.

1.  ACCOUNTING POLICIES (CONTINUED)

INCOME TAXES

The Company accounted for income taxes under the provisions of Accounting
Principles Board Opinion Number 11 through September 30, 1992. Statement of
Financial Accounting Standard No. 109, "Accounting for Income Taxes" was issued
by the Financial Accounting Standards Board in February 1992 and was adopted by
the Company as of October 1, 1992 (see Note 6).

RESEARCH AND DEVELOPMENT

During the years ended September 30, 1994 and 1993, research and development
expense of approximately $1,347,000 and $1,435,000, respectively, was charged to
expense as incurred.

FOREIGN CURRENCY TRANSLATION

The financial statements of foreign subsidiaries have been translated into U.S.
dollars in accordance with FASB Statement No. 52. All balance sheet accounts
have been translated using the current exchange rates at the balance sheet date.
Income statement amounts have been translated using the average exchange rate
for the year. The gains and losses resulting from the change in exchange rates
from year to year have been reported separately as a component of stockholders'
equity (deficit). The effect on the statement of operations of transaction gains
and losses is insignificant.

RECLASSIFICATIONS

Certain amounts in the 1993 financial statements have been changed to conform
them to the 1994 presentation.

6.  INCOME TAXES

Effective October 1, 1992, the Company changed its method of accounting for
income taxes from the deferred method too the liability method required by FASB
Statement No. 109, "Accounting for Income Taxes" (FAS 109). As permitted under
the new rules, prior years' financial statements have not been restated. The
cumulative effect of adopting FAS 109 as of October 1, 1992 was to increase the
net loss by $827,000.

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets as of September 30, 1994 are as follows:

</TABLE>

The valuation allowance decreased by $2,393,000 during 1994 based upon
management's assessment that a valuation allowance was no longer required with
the recent improvements in the Company's financial results. During 1993, the
valuation allowance was increased by $1,330,000 from the amount existing at
adoption based on that year's losses.

The Company's effective tax rate differs from the statutory rates primarily due
to the noninclusion of foreign income and (losses) of approximately $223,000,
net, in 1994 and $(159,000), net, in 1993, utilization of net operating loss
carryforwards, as well as the deferred tax asset valuation allowance changes
during 1994 and 1993.

At September 30, 1994, the Company had a net operating loss carryforward of
approximately $3,950,000 for state income tax purposes which expires during 1996
through 1998.

7.  COMMON STOCK GRANTS AND OPTIONS

In May 1990, the Board of Directors granted certain officers and employees
common stock grants as compensation and additional incentive to provide
continued services to the Company. The stock was granted at its fair market
value as determined by management at the date of the grant. If the officers' or
employees' employment with the Company is terminated during the four year
incentive period for any reason, the officer or employee shall be required to
forfeit all unvested stock issued under the stock grant program. The Company
charged to expense, under the stock grant program, $24,000 and $29,000 as
compensation in 1994 and 1993, respectively.

The Board of Directors of the Company granted a certain consulting firm, which
is providing executive and other consulting services to the Company, options to
purchase 50,000 shares of its authorized but unissued common stock at a price of
$23 per share (amended to $6.50 per share subsequent to year-end), protected
against dilution, as defined, and expiring in August 1999. The price per share
exceeded the fair market value at the date of the grant. These stock options
shall be contingent upon the Company's stock being publicly traded, or the
Company being

             Notes to Consolidated Financial Statements (continued)



7.  COMMON STOCK GRANTS AND OPTIONS (CONTINUED)

merged into or acquired by a private or publicly owned concern, and if such
event occurs, the stock options will vest 100 percent and shall be exercisable
only within 90 days after such event. The stock options shall vest 25 percent on
August 1, 1992, and 25 percent each year thereafter provided that the consulting
firm shall be, each vesting date, still performing the services required of
them.

Subsequent to year-end, the Board authorized the implementation of an incentive
stock option plan for certain employees. Under the plan, options to purchase
common stock of the Company will be granted to certain employees at the fair
market value of the underlying common stock. Up to 250,000 shares may be offered
under this plan.

8.  LIFE INSURANCE PROCEEDS

During 1993, the Company received proceeds of approximately $1,000,000 from a
claim filed under a key man life insurance policy due to the death of a member
of the Board of Directors. The proceeds are recorded in other income in the 1993
financial statements.

9.  CONTINGENCIES

The Company is a party to legal proceedings which arise out of the ordinary
course of business. Based upon advice from outside legal counsel, management is
of the opinion that these matters will have no material effect on the Company's
consolidated financial position.

10.  BENEFIT PLAN

During 1990, the Company's Board of Directors elected to establish the Rockford
Corporation 401(k) Retirement Savings Plan (Plan) covering substantially all
employees who have completed six consecutive months of service without regard to
hours of service. Under the terms of the Plan, employees may make voluntary
contributions, subject to Internal Revenue Service limitations. The company will
match employee contributions up to three percent of the employee's annual
compensation. Additional contributions to the Plan can be made at the discretion
of the Board of Directors. Contributions to the Plan during the years ended
September 30, 1994 and 1993 were approximately $140,000 and $71,000,
respectively.

                 BRIDGE LOAN CONVERSION AND EXTENSION AGREEMENT


         This Agreement is between Rockford Corporation, an Arizona corporation
("Borrower") and Caroline S. Bartol ("Lender"). Borrower and Lender agree as
follows:

1.       RECITALS.

         1.1      Borrower Business. Borrower manufacturers high quality auto
                  and professional audio equipment, including amplifiers,
                  speakers, source units, and accessories.

         1.2      Loan. Lender provided a $2,000,000 loan (the "Bridge Loan") to
                  Borrower to help finance working capital and general corporate
                  needs of Borrower pursuant to a Bridge Loan Agreement (the
                  "Original Agreement") attached as Exhibit A.

         1.3      Conversion and Extension. Lender and Borrower have agreed to
                  (a) convert $999,999 of the Bridge Loan principal into 67,340
                  shares of Borrower's common stock (a price of $14.85 per
                  share) and (b) extend the balance of the Bridge Loan, or
                  $1,000,001 of principal, so that its due date is December 31,
                  1996.

         1.4      Purpose. The purpose of this Agreement is to set forth the
                  terms of the agreement to convert and extend the terms of the
                  Bridge Loan.

2.       CONVERSION AGREEMENT. Lender subscribes to purchase, and Borrower
         promises to issue, 67,340 shares of Borrower's common stock, par value
         $0.01 per share (the "Shares"), for a purchase price of $14.85 per
         share or $999,999 in the aggregate. The purchase price is payable by
         conversion of $999,999 of the Bridge Loan principal into capital of
         Borrower and Lender instructs Borrower to convert such principal into
         capital upon issuance and delivery of the Shares to Lender.

         In connection with the purchase of the Shares, Lender represents and
         acknowledges as follows:


         2.1      Investment Intent. Lender is acquiring the Shares for
                  investment and not with a view to their resale or
                  distribution. Lender has no contract, undertaking, agreement,
                  or arrangement with any person to sell, transfer or pledge the
                  Shares and has no present plans to enter into any such
                  contract, undertaking, agreement, or arrangement.

         2.2      Securities Registration. The Shares are offered and sold
                  without registration under the Securities Act of 1933 (the
                  "Act") or the Arizona Securities Act, in reliance upon one or
                  more exemptions available under the Act and under Arizona Law
                  for non-public offerings.

         2.3      Legend on Shares. The certificates evidencing the Shares will
                  bear a legend giving notice of the restrictions on transfer of
                  the Shares resulting from their sale in reliance on exemptions
                  from registration under applicable state securities laws.
<PAGE>   2
         2.4      Accredited Investor. Lender is an Accredited Investor as that
                  term is defined in the rules of the Securities and Exchange
                  Commission.

         2.5      Risk. Lender has the financial ability to bear the economic
                  risk of Lender's investment in the Shares (including its
                  possible loss). Lender has adequate means for providing for
                  Lender's current needs and personal contingencies and has no
                  need for liquidity with respect to Lender's investment in the
                  Shares. Lender has (alone or together with Lender's advisers
                  and family) such knowledge and experience in financial and
                  business matters as to be capable of evaluating the merits and
                  risks of an investment in the Shares and has obtained, in
                  Lender's judgment, sufficient information to evaluate the
                  merits and risks of an investment in the Shares.

         2.6      Information Supplied. Lender (alone or with representatives)
                  has had opportunity to ask questions of and receive
                  satisfactory answers from the Borrower and its officers and
                  directors concerning the business and prospects of the
                  Borrower and has had the opportunity to review such documents,
                  records, books, and other information as Lender has deemed
                  necessary in order to make an investment decision with respect
                  to the purchase of the Shares. In making the decision to
                  purchase the Shares subscribed for, Lender has relied solely
                  on independent investigations and on documents supplied by
                  Company.

3.       EXTENSION AGREEMENT. Lender extends the balance of the Bridge Loan
         after conversion, $1,000,001 (the "Loan") on the terms set forth in
         this agreement. Borrower will execute and deliver to Lender a
         promissory note (the "Note") in the form of Exhibit A, in exchange for
         Lender's delivery to Borrower of the original promissory note
         evidencing the Bridge Loan. Borrower will (a) maintain accurate records
         of the original principal amount, payments made, and interest and other
         charges in connection with the Loan and (b) render to Lender on
         request, and at least monthly, an account statement showing such
         amounts.

4.       INTEREST. The outstanding principal and unpaid interest under this
         Agreement will bear interest at the rate of 9% per annum. Interest is
         payable monthly on the first day of each month.

5.       REPAYMENT OF PRINCIPAL AND OPTION. Borrower will pay the principal on
         the Note on December 31, 1996. Borrower grants Lender an option to
         purchase additional shares of Borrower's Common Stock (the "Option
         Shares") by conversion of the Loan at any time before its repayment by
         Borrower. The price for the Option Shares will be (a) the most recent
         price at which Borrower has sold its shares to an unaffiliated third
         party in a transaction concluded after the date of this Agreement of
         (b) $14.85 per share, if Borrower has not sold its shares in such a
         transaction. Lender may purchase up to the number of Option Shares
         computed by dividing the outstanding principal of the Loan by the price
         per share established in the immediately preceding sentence. In
         connection with any purchase of Option Shares, Lender will provide
         Borrower with representations comparable to those set forth in Section
         2 above.

6.       SUBORDINATION TO BANK LOAN. The Loan is subordinate to Borrower's
         obligations under its loan (the "Bank Loan") with its principal lender,
         Wells Fargo Bank, formerly First Interstate Bank of Arizona (the
         "Bank"). All Borrower's obligations to Bank must be first paid to Bank
         in full before any payments may be made under this Loan, except for:

         6.1      payments of interest when due;

         6.2      payments of principal paid from proceeds of a capital
                  investment by Lender or its affiliates in Borrower; and

         6.3      payments of principal when due on December 31, 1996, but only
                  if (a) Bank has not given Borrower notice that it is in
                  default or non-compliance under the Bank Loan and (b) the
                  payment of principal would not cause Borrower to be out of
                  compliance under the Bank Loan either (i) as of the date made,
                  (ii) as of the most recent quarterly compliance date under the
                  Bank Loan (assuming the payment had been made on the last day
                  of such quarter), or (iii) as of the next quarterly compliance
                  date under the Bank Loan (based on Borrower's current
                  projected financial statements). If Borrower makes a payment
                  of principal, Borrower will deliver to Lender and Bank a
                  certificate confirming that these conditions are satisfied.

         6.4      If there is an Event of Default under Section 9.4 below, then
                  Borrower and its officers, assigns, trustee, receiver, and
                  other representative are directed to pay Bank the full amount
                  of the Bank Loan before making any payments to Lender other
                  than payments of principal out of proceeds of the investment
                  by Lender or its affiliates in Borrower.

7.       NO SECURITY. The Loan is unsecured but constitutes a general obligation
         of Borrower.

8.       MANAGEMENT BONUS PLAN. If Borrower establishes a management bonus plan
         for its fiscal years 1997, 1998, or 1999 Borrower's compensation
         committee and management will provide Lender with a written explanation
         of any differences between (a) the income projections used to establish
         fiscal 1997, 1998, and 1999 bonus levels in the plan and (b) the income
         projections used by Vrolyk and Company in its evaluation of the value
         of Borrower's common stock.

9.       ADDITIONAL DOCUMENTS. Borrower will execute and deliver to lender
         additional documents as necessary to carry out the purposes of this
         Agreement.

10.      EVENTS OF DEFAULT. The following events are "Events of Default":

         10.1     Borrower fails to pay any amount under this Agreement when due
                  and payable;

         10.2     Borrower fails or neglects to perform, keep, or observe any
                  term, provision, condition, covenant, representation, or
                  warranty contained in this Agreement;

         10.3     Borrower becomes insolvent; or

         10.4     A complaint or case is filed by or against borrower under
                  federal bankruptcy laws and is not dismissed within 60 days of
                  filing; Borrower admits to inability to pay or fails to pay
                  Borrower's debts generally as they mature; Borrower makes an
                  assignment for the benefit of creditors; a receiver is
                  appointed for Borrower; or any other insolvency proceedings
                  are instituted by or against Borrower and are not dismissed
                  within 60 days of filing.

11.      ACCELERATION OF OBLIGATIONS AND REMEDIES. If there is an event of
         default, the outstanding Loan balance and all other amounts owed by
         Borrower to Lender will, if Lender elects, become immediately due and
         payable without notice to or demand upon Borrower of any kind. Any
         acceleration, if elected by Lender, is subject to all applicable laws.

12.      USURY SAVINGS CLAUSE. Borrower will not, upon acceleration of maturity
         by Lender or otherwise, be required to pay any interest in excess of
         the maximum amount permitted by law.

13.      MISCELLANEOUS.

         13.1     Waiver of Defaults. Lender may, in its sole discretion, waive
                  a default or cure at Borrower's expense a default. Any waiver
                  in a particular instance or of a particular default is not a
                  waiver of other defaults or of the same kind or default at
                  another time.

         13.2     Entire Agreement; Amendments. This Agreement is the entire
                  Agreement of the parties with respect to its subject matter

                  of each party.

         13.3     Severability. If any part (or parts) of this Agreement is
                  invalid, illegal, or unenforceable in any respect, such
                  invalidity, illegality or unenforceability will not effect any
                  provisions of this Agreement, and this Agreement will be
                  construed as if the invalid, illegal, or unenforceable
                  provision were omitted, provided that such construction and
                  omission is consistent with the general intent of the parties
                  as evidenced by this Agreement considered as an entirety.

         13.4     Notices. Notices required under this Agreement are effective

         1.3.     Purpose. The purpose of this Agreement is to set forth the
                  terms of Lender's agreement to lend to Borrower $2,000,000.

2.       LOAN AGREEMENT. Lender will loan Borrower $2,000,000 (the "Loan") on
         the terms set forth in this agreement. Borrower will execute and
         deliver to Lender a promissory note (the "Note") in the form of Exhibit
         A. Lender will advance the amount of the Loan as of the date of this
         Agreement. Borrower will (a) maintain accurate records of the amount
         advanced, payments made, and interest and other charges in connection
         with the Loan and (b) render to Lender on request, and at least
         monthly, an account statement showing such amounts.

3.       USE OF MONIES LOANED. Borrower will use the amount loaned to for
         working capital, to reduce other debt, and to pay trade accounts
         payable.

4.       INTEREST. The outstanding principal and unpaid interest under this
         Agreement will bear interest at the rate of 9% per annum. Interest is
         payable monthly on the first day of each month.

5.       REPAYMENT OF PRINCIPAL. It is intended that this Loan is a "bridge"
         loan in advance of an investment by Lender or its affiliates in
         Borrower of not less than the principal amount of the Loan. The Loan
         will be repaid out of the investment by Lender or its affiliates.
         Borrower will pay the principal on the Note on the earlier of (a)
         receipt of the proceeds of the capital investment in Borrower committed
         by Lender or its affiliates or (b) September 30, 1996.

6.       SUBORDINATION TO BANK LOAN. The Loan is subordinate to Borrower's
         obligations under its loan (the "Bank Loan") with its principal lender,
         First Interstate Bank of Arizona (the "Bank"). All Borrower's
         obligations to Bank must be first paid to Bank in full before any
         payments may be made under this Loan, except for:
<PAGE>   2
         6.1.     payments of interest when due;

         6.2.     payments of principal paid from proceeds of the capital
                  investment by Lender or its affiliates in Borrower; and

         6.3.     payments of principal when due on September 30, 1996, but only
                  if (a) Bank has not given Borrower notice that it is in
                  default or non-compliance under the Bank Loan and (b) the
                  payment of principal would not cause Borrower to be out of
                  compliance under the Bank Loan either (i) as of the date made,
                  (ii) as of the most recent quarterly compliance date under the
                  Bank Loan (assuming the payment had been made on the last day
                  of such quarter), or (iii) as of the next quarterly compliance
                  date under the Bank Loan (based on Borrower's current
                  projected financial statements). If Borrower makes a payment
                  of principal, Borrower will deliver to Lender and Bank a
                  certificate confirming that these conditions are satisfied.

         6.4.     If there is an Event of Default under Section 9.4 below, then
                  Borrower and its officers, assigns, trustee, receiver, and
                  other representative are directed to pay Bank the full amount
                  of the Bank Loan before making any payments to Lender other
                  than payments of principal out of proceeds of the investment
                  by Lender or its affiliates in Borrower.

7.       NO SECURITY. The Loan is unsecured but constitutes a general obligation
         of Borrower.

8.       ADDITIONAL DOCUMENTS. Borrower will execute and deliver to Lender
         additional documents as necessary to carry out the purposes of this
         Agreement.

9.       EVENTS OF DEFAULT. The following events are "Events of Default":

         9.1.     Borrower fails to pay any amount under this Agreement when due
                  and payable;

         9.2.     Borrower fails or neglects to perform, keep, or observe any
                  term, provision, condition, covenant, representation, or
                  warranty contained in this Agreement;

         9.3.     Borrower becomes insolvent; or

         9.4.     A complaint or case is filed by or against borrower under
                  federal bankruptcy laws and is not dismissed within 60 days of
                  filing; Borrower admits to inability to pay or fails to pay
                  Borrower's debts generally as they mature; Borrower makes an
                  assignment for the benefit of creditors; a receiver is
                  appointed for Borrower; or any other insolvency proceedings
                  are instituted by or against Borrower and are not dismissed
                  within 60 days of filing.

         default, the outstanding Loan balance and all other amounts owed by
         Borrower to Lender will, if Lender elects, become immediately due and

         acceleration, if elected by Lender, is subject to all applicable laws.

11.      USURY SAVINGS CLAUSE. Borrower will not, upon acceleration of maturity
         by Lender or otherwise, be required to pay any interest in excess of

         12.1.    Waiver of Defaults. Lender may, in its sole discretion, waive
                  a default or cure at Borrower's expense a default. Any waiver
                  in a particular instance or of a particular default is not a
                  waiver of other defaults or of the same kind of default at
                  another time.

         12.2.    Entire Agreement; Amendments. This Agreement is the entire

                  of each party.

         12.3.    Severability. If any part (or parts) of this Agreement is
                  invalid, illegal, or unenforceable in any respect, such
                  invalidity, illegality or unenforceability will not effect any
                  other provisions of this Agreement, and this Agreement will be
                  construed as if the invalid, illegal, or unenforceable
                  provision were omitted, provided that such construction and
                  omission is consistent with the general intent of the parties
                  as evidenced by this Agreement considered as an entirety.

         12.4.    Notices. Notices required under this Agreement are effective

                  the parties shown on the signature page of this Agreement
                  (which may be changed by notice).

         12.5.    Governing Law. This Agreement is governed by the laws of

         12.7.    Counterparts. This Agreement may be executed in counterparts

                  outstanding from time to time at the Capex Loans Interest
                  Rate, but in any event upon such terms and subject to such
                  conditions as are set forth on the promissory note of Borrower
                  evidencing the aggregate amount of all Capex Loans (the "Capex
                  Note"), in form and substance satisfactory to Lender in its
                  sole discretion, upon the following terms and subject to the
                  following conditions: (a) Lender shall have no obligation to
                  make a Capex Loan which, without giving effect to any
                  amortization or repayment of the Capex Loans, would cause the
                  aggregate amount of all Capex Loans advanced hereunder to
                  exceed the amount of One Million and No/100 Dollars
                  ($1,000,000.00); (b) the Capex Loans, if any, shall be
                  evidenced by the Capex Note, and otherwise shall be made on

                  herein, (c) Borrower shall have notified Lender in writing not
                  less than one (1) Business Day prior to the date upon which
                  the Capex Loan is to be made, specifying the amount of such
                  Capex Loan and the Capital Expenditure acquisition to be
                  financed thereby; (d) each Capex Loan (other than a Capex Loan
                  which makes the aggregate of all Capex Loans equal to
                  $1,000,000) shall be in the amount of at least Fifty Thousand
                  and No/100 Dollars (S50,000.00); (e) Lender shall be satisfied
                  that it will receive a purchase money security interest in the
                  Equipment to be financed by and acquired with the proceeds of
                  the Capex Loan; (f) no Capex Loan shall exceed the amount of
                  eighty percent (80.0%) of the "hard" acquisition costs
                  (excluding without limitation installation, training,
                  supplies, ancillary or accessory items or similar "soft"
                  costs) of the Equipment to be acquired with the proceeds of
                  such Capex Loan; (g) Borrower may not request more than two
                  (2) Capex Loans during any calendar month; (h) Lender may, in

                  to the seller of the Equipment to be financed by such Capex
                  Loan and to require Borrower to execute and to deliver to
                  Lender prior to funding of such Capex Loan a UCC-I Financing
                  Statement concerning such Equipment to be acquired; (i) Lender
                  shall have no obligation to make any Capex Loan if, either
                  before or after giving effect to such requested Capex Loan,
                  Borrower would not be in compliance with the financial
                  covenants set forth in Section 13.14 of this Agreement or any
                  other term or condition of this Agreement; and (j) to the
                  extent not contrary to this paragraph, the terms and
                  conditions applicable to all advances of any Loans shall apply
                  to any Capex Loan. The outstanding and unpaid principal
                  balance of and all accrued and unpaid interest on all Capex
                  Loans shall in all events be due and payable on the earlier to

CONDITIONS PRECEDENT (SECTION 2.1):

                  The obligation of Lender to make the initial advance hereunder
                  is subject to the fulfillment, to the satisfaction of Lender
                  and its counsel, of each of the following conditions, in
                  addition to the conditions set forth in Sections 2.1 and 2.2
                  above: (a) Excess Availability. Borrower shall have excess
                  borrowing availability under the Receivables Loans facility of
                  not less than Five Hundred Thousand and No/100 Dollars
                  ($500,000.00), after giving effect to the initial advance

                  suppliers' respective written or agreed-upon terms of payment.
                  (b) Opinions. To the extent any persons other than Borrower
                  and Lender shall be parties to the Loan Documents, Lender
                  reserves the right to require satisfactory opinions of counsel
                  for each such person concerning the proper organization of
                  such person and the due authorization, execution, delivery,
                  enforceability, validity and binding effect of the Loan
                  Documents to which such person is a party. Each such opinion
                  of counsel shall confirm, to the satisfaction of Lender, that
                  the opinion is being

<PAGE>   4
                  delivered to Lender at the instruction of the party
                  represented by such counsel, that Lender is entitled to rely
                  on such opinion, and that for purposes of such reliance Lender
                  is deemed to be in privity with the opining counsel. (c)
                  Review of Material Agreements. Prior to Closing, Lender shall

                  documents in respect of the borrowing of money, all joint
                  venture agreements, royalty agreements, license agreements,
                  employment/management incentive agreements, all non-compete
                  agreements to which Borrower is a party, and such other

                  Lender may require in its sole discretion that Borrower, enter

                  Borrower's employees. (e) Approval of Projections. Lender
                  shall have received and approved cash flow projections and a

                  the proposed Loans, together with any equity investment
                  required of Borrower by Lender under this Agreement, will
                  satisfy Borrower's projected working capital needs; and (ii)
                  that following the Closing of the Loans, (A) the then present
                  fair market value of the assets of Borrower will be greater
                  than the total amount of liabilities, including contingent,
                  subordinated, absolute, fixed, matured or unmatured and
                  liquidated or unliquidated liabilities, of Borrower, (B) the
                  present fair market value of the assets of Borrower will be

                  a "solvency opinion" acceptable in all respects to Lender in
                  its sole discretion, and (F) Borrower will have reasonably

                  the initial advance hereunder. (f) UCC, Lien Searches. Lender
                  shall have received and approved the results of UCC, tax lien,
                  litigation, judgment, and bankruptcy searches regarding

INTEREST AND FEES (SECTION 3.1):

      I.    REVOLVING LOANS.

      A.    Interest.

                  (i) Rates of Interest. The Revolving Loans shall bear interest
      on the unpaid principal amount thereof from the date such Revolving Loans
      are made and until paid in full at one of the following rates, as selected
      by Borrower from time to time as provided in this Section:

                        (a) Base Rate Option (Receivables Loans and Inventory
            Loans only). That portion of the outstanding principal balance of
            the Receivables Loans and the Inventory Loans subject to this option
            shall bear interest at a fluctuating rate per annum equal at all
            times to one percent (1.0%) in excess of the Base Rate;

                        (b) LIBO Rate Option (Receivables Loans and Inventory
            Loans only). That portion of the outstanding principal balance of
            the Receivables Loans and the Inventory Loans subject to this option
            shall bear interest at a fixed rate per annum equal to three and
            one-quarter percent (3.250%) in excess of the LIBO Rate applicable
            to such LIBO Rate Portion;

                        (c) Base Rate Option (Seasonal Loans only). That portion
            of the outstanding principal balance of the Seasonal Loans subject
            to this option shall bear interest at a fluctuating rate per annum
            equal at all times to three percent (3.0%) in excess of the Base
            Rate; and

                        (d) LIBO Rate Option (Seasonal Loans only). That portion
            of the outstanding principal balance of the Seasonal Loans subject
            to this option shall bear interest at a fixed rate per annum equal
            to five and one-quarter percent (5.250%) in excess of the LIBO Rate
            applicable to such LIBO Rate Portion.

            Notwithstanding the foregoing, if for Borrower's fiscal year ending
            December 31, 1997 Borrower's EBITDA exceeds the amount of $5,500,000
            and Borrower's Senior Debt Coverage exceeds 1.40 to 1.0, as
            determined by the audited financial statements to be provided
            pursuant to Section 5.2 of this Agreement, then (effective on the
            first day of the calendar month first following Lender's review and
            approval of such audited financial statements and the calculations
            of EBITDA and Senior Debt Coverage Ratio) the applicable Margin
            otherwise added to the Base Rate or the LIBO Rate, as applicable,
            shall be reduced by subtracting therefrom one-quarter of one percent
            (0.250%); provided, however, that if for any consecutive
            twelve-calendar-month period ending after December 31, 1997
            Borrower's EBITDA does not exceed the amount of $5,500,000 or
            Borrower's Senior Debt Coverage Ratio does not exceed 1.40 to 1.0,
            as determined by Lender, then (effective on the first day of the
            calendar month first following such determination and at all times
            thereafter) the applicable Margin shall revert to that provided in
            subparagraphs (a) through (d) above.

                        The interest rate chargeable hereunder shall be
            increased or decreased, as the case may be, without notice or demand
            of any kind, upon the announcement of any change in the Base Rate.
            Each change in the Base Rate shall be effective hereunder on the
            first day following the announcement of such change, provided, that
            a cumulative change of less than one-fourth of one percent (0.25%)
            shall not be considered. Interest charges and all other fees and
            charges herein shall be computed on the basis of a year of 360 days
            and actual days elapsed and shall be payable to Lender in arrears on
            the first day of each month.

                        If on any day notice has not been timely delivered by
            Borrower to Lender in accordance with the terms of this Agreement
            specifying the basis for determining the rate of interest on that
            day, then for that day Borrower shall be deemed to have selected the
            Base Rate Option. The outstanding principal


                                     - 5 -
<PAGE>   6
            balance of Obligations other than the Loans shall bear interest from
            the date such Obligations are incurred until paid in full based upon
            the Base Rate Option. Notwithstanding anything contained herein to
            the contrary, Borrower may not select the LIBO Rate Option if an
            Event of Default exists.

                  (ii) Interest Payments. With respect to any Base Rate
      Portion, accrued interest shall be payable, in arrears, (A) on the first
      day of each calendar month, and (B) at maturity (whether by acceleration
      or otherwise) of the Revolving Loans. With respect to any LIBO Rate
      Portion (and if the Interest Period applicable thereto is longer than
      three (3) months, also ninety (90) days after the be-inning of such
      Interest Period), accrued interest shall be payable (A) on the last day of
      the applicable Interest Period for such LIBO Rate Portion, and (B) at
      maturity (whether by acceleration or otherwise) of the Revolving Loans.

                  (iii) Conversion or Continuation.

                        (a) Subject to the provisions of this Agreement,
            Borrower shall have the option (A) as of any date to convert all or
            any part of its outstanding Base Rate Portion, if any, into one or
            more LIBO Rate Portions; (B) as of the last day of its applicable
            Interest Period, to convert all or any part of a LIBO Rate Portion
            to a Base Rate Portion on such expiration date; or (C) as of the
            last day of any Interest Period, to continue all or any part of a
            LIBO Rate Portion, and, in the case of clauses (B) and (C) of this
            paragraph, the succeeding Interest Period of such continued LIBO
            Rate Portion shall commence on such expiration date; provided,
            however, no outstanding portion of the Revolving Loans may be
            continued as, or be converted into, a LIBO Rate Portion (i) if the
            continuation of, or the conversion into such LIBO Rate Portion,
            would violate any of the provisions of Section 3.1(1)(A)(v) of this
            Schedule or (ii) if as of such date a Default or an Event of Default
            would occur or has occurred and is continuing.

                        (b) To convert or continue a LIBO Rate Portion under
            this Section 3.1(I)(A)(iii). Borrower shall deliver a Notice of
            Conversion/Continuation, in the form of Exhibit A attached hereto
            and incorporated herein by this reference, to Lender no later than
            10:00 a.m. (Los Angeles time) at least three (3) Business Days in
            advance of the proposed conversion/continuation date. A Notice of
            Conversion/Continuation shall specify (A) the proposed
            conversion/continuation date (which shall be a Business Day), (B)
            the amount of the principal portion of the Revolving Loans to be
            converted/continued, and (C) whether such portion shall be converted
            and/or continued. In lieu of delivering a Notice of
            Conversion/Continuation, Borrower may give Lender telephonic notice
            of any proposed conversion/continuation by the time required under
            this Section 3.l(I)(A)(iii), and such notice shall be confirmed in
            writing delivered to Lender promptly (but in no event later than
            3:00 p.m. (Los Angeles time) on the same Business Day). Any Notice
            of Conversion/Continuation delivered by Borrower (or telephonic
            notice in lieu thereof) shall be irrevocable when given pursuant to
            this clause (b) (whether given in writing or by telephone), and
            Borrower shall be bound to convert or continue in accordance
            therewith.

                  (iv) Computation of Interest. In computing interest, the date
      of the making of the Revolving Loans, the first day of an Interest Period
      or the date of any conversion into the Base Rate Portion, as the case may
      be, shall be included and the date of payment, the expiration date of the
      Interest Period or the date of any conversion from the Base Rate Portion,
      as the case may be, shall be excluded so long as payment is timely
      received in accordance with this Agreement.

                  (v) Special Provisions Governing Borrower's Selection of the
      LIBO Rate-Option. With respect to the LIBO Rate Portion:

                        (a) Amount of LIBO Rate Portion. Each LIBO Rate Portion
            shall be for a minimum amount of One Million Dollars ($1,000,000)
            and in integral multiples of One Hundred Thousand Dollars ($100,000)
            in excess of that amount. Further, the aggregate outstanding
            principal amount of all LIBO Rate Portions shall not exceed the
            amount of Eleven Million Five Hundred Thousand and No/100 Dollars
            ($11,500,000).

                        (b) Determination of Interest Period. By giving notice
            as set fourth in Section 3.1(I)(A)(iii) of the Schedule, Borrower
            shall have the option, subject to the other provisions of this


                                     - 6 -
<PAGE>   7
            Section 3.1(I)(A)(v), to select an interest period (each, an
            "Interest Period") to apply to each LIBO Rate Portion described in
            such notice, subject to the following provisions:

                              (1) Borrower may only select an Interest Period of
                  one (1), two (2), three (3) or six (6) months in duration;

                              (2) In the case of immediately successive Interest
                  Periods applicable to the LIBO Rate Portion, each successive
                  Interest Period shall commence on the day on which the next
                  preceding Interest Period expires;

                              (3) If any Interest Period would otherwise expire
                  on a day which is not a Business Day, such Interest Period
                  shall be extended to expire on the next succeeding Business
                  Day if the next succeeding Business Day occurs in the same
                  calendar month, and if there will be no succeeding Business
                  Day in such calendar month, the Interest Period shall expire
                  on the immediately preceding Business Day;

                              (4) Borrower may not select an Interest Period as
                  to any LIBO Rate Portion if such Interest Period expires after
                  a scheduled date of termination of this Agreement; and

                              (5) There shall be no more than three (3) Interest
                  Periods in effect at any one time.

                        (c) Determination of LIBO Rate. As soon as practicable
            on the second Business Day prior to the first day of each Interest
            Period (the "Interest Rate Determination Date"), Lender shall
            determine (pursuant to the definition of "LIBO Rate") the interest
            rate which shall apply to the LIBO Rate Portion for which an
            interest rate is then being determined and shall promptly give
            notice thereof (in writing or by telephone confirmed in writing) to
            Borrower. Lender's determination shall be presumed to be correct,
            absent manifest error, and shall be binding upon Borrower, absent
            manifest error.

                  (vi) Special Provisions Governing LIBO Rate Portions.
      Notwithstanding any other provision of this Agreement, the following
      provisions shall govern with respect to LIBO Rate Portions as to the
      matters covered:

                        (a) In the event Lender shall have determined (which
            determination shall be final and conclusive and binding upon all
            parties hereto), on any Interest Rate Determination Date with
            respect to any LIBO Rate Portions, that by reason of circumstances
            affecting the interbank Eurodollar market, adequate and fair means
            do not exist for determining the interest rate applicable to such
            LIBO Rate Portions on the basis provided for in the definition of
            LIBO Rate, Lender shall on such date give notice (by telecopy or by
            telephone confirmed in writing) to Borrower of such determination,
            whereupon (1) no Revolving Loans may be made as, or converted into,
            LIBO Rate Portions until such time as Lender notifies Borrower that
            the circumstances giving rise to such notice no longer exist and (2)
            any Notice of Conversion/Continuation given by Borrower with respect
            to the Revolving Loans in respect of which such determination was
            made shall be deemed to be modified by Borrower and the LIBO Rate
            Portions then being requested shall be made or continued by Lender
            as Base Rate Portions.

                        (b) If Lender shall have determined (which determination
            shall be final and conclusive and binding upon all parties), with
            respect to any LIBO Rate Portion and any pending Interest Period
            that by reason of (a) any change after the date hereof in any
            applicable law or governmental rule, regulation or order (or any
            interpretation thereof and including the introduction of any new law
            or governmental rule, regulation or order) or (b) other
            circumstances affecting Lender or the LIBO market or the position of
            Lender or its affiliates in such market (such as for example, but
            not limited to, official reserve requirements required by Regulation
            D to the extent not given effect in the LIBO Rate), the LIBO Rate
            shall no longer represent the effective pricing to Lender for U.S.
            Dollar deposits of comparable amounts for the relevant period, then,
            and in any such event, Lender shall promptly (and in any event as
            soon as possible after being notified of a borrowing, conversion or
            continuation) give notice (by telephone


                                     - 7 -
<PAGE>   8
            confirmed in writing) to Borrower of such determination. Thereafter,
            Borrower shall pay to Lender, upon written demand therefor, such
            additional amounts in the form of an increased interest rate of, or
            a different method of calculating, interest or otherwise as Lender
            shall reasonably determine. A certificate as to additional amounts
            owed Lender, showing in reasonable detail the basis for the
            calculation thereof, submitted in good faith and on a reasonable
            basis to Borrower by Lender shall, absent manifest error, be final
            and conclusive and binding upon all of the parties hereto.

                        (c) If on any date Lender shall have reasonably
            determined (which determination shall be final and conclusive and
            binding upon all parties) that the making or continuation of its
            LIBO Rate Portions has become unlawful or impossible under any law,
            governmental rule, regulation or order with which Lender believes,
            in good faith, it must comply (whether or not having the force of
            law and whether or not failure to comply therewith would be
            unlawful), then, and in any such event, Lender shall promptly give
            notice (by telephone confirmed in writing) to Borrower of that
            determination. Subject to the prior withdrawal of a Notice of
            Conversion/Continuation or prepayment of the LIBO Rate Portions as
            contemplated by the following subsection, the obligation of Lender
            to make or maintain the LIBO Rate Portions during any such period
            shall be terminated at the earlier of the termination of the
            Interest Period then in effect or when required by law and Borrower
            shall no later than the termination of the Interest Period in effect
            at the time any such determination pursuant to this subsection is
            made or, earlier, when required by law, repay or prepay the LIBO
            Rate Portions, together with all interest accrued thereon.

                        (d) In lieu of paying Lender such additional moneys as
            are required by Section 3.1(I)(A)(vi)(b) or the prepayment of Lender
            required by Section 3.1(I)(A)(vi)(c), Borrower may exercise any one
            of the following options:

                              (1) If the determination by Lender relates only to
                  LIBO Rate Portions then being requested by Borrower pursuant
                  to a Notice of Conversion/Continuation, Borrower may by giving
                  notice (by telephone confirmed in writing) to Lender no later
                  than the date immediately prior to the date on which such LIBO
                  Rate Portions are to be made, withdraw that Notice of
                  Conversion/Continuation and the LIBO Rate Portions then being
                  requested shall be made by Lender as Base Rate Portions; or

                              (2) Upon written notice to Lender, Borrower may
                  terminate the obligations of Lender to make or maintain the
                  Revolving Loans as, and to convert the Revolving Loans into,
                  LIBO Rate Portions and in such event, Borrower shall, prior to
                  the time any payment pursuant to Section 3.1(I)(A)(vi)(c) is
                  required to be made or if the provisions of Section
                  3.1(I)(A)(vi)(b) are applicable, at the end of the then
                  current Interest Period, convert all of the LIBO Rate Portions
                  into Base Rate Portions but without satisfying the advance
                  notice requirements therein.

                        (e) Borrower shall compensate Lender, upon written
            request by Lender (which request shall set forth in reasonable
            detail the basis for requesting such amounts and which shall, absent
            manifest error, be conclusive and binding upon all parties hereto),
            for all reasonable losses, expenses and liabilities (including,
            without limitation, any loss (including interest paid) sustained by
            Lender in connection with the re-employment of such funds) Lender
            may sustain: (1) if for any reason (other than a default by Lender)
            a borrowing of any LIBO Rate Portions does not occur on a date
            specified therefor in a Notice of Conversion/Continuation or a
            telephonic request for borrowing or conversion/continuation therefor
            is given pursuant to Section 3.1(I); (2) if any prepayment of any
            LIBO Rate Portion occurs on a date that is not the last day of an
            Interest Period applicable to that LIBO Rate; (3) if any prepayment
            of any LIBO Rate Portion is not made on any date specified in a
            notice of prepayment given by Borrower; or (4) as a consequence of
            any other default by Borrower to repay any LIBO Rate Portions when
            required by the terms of this Agreement.

                        (f) Except as provided in Section 3.1(I)(A)(vi)(b) with
            respect to certain determinations on Interest Rate Determination
            Dates, if, after the date hereof by reason of, (1) the introduction
            of or any change (including, without limitation, any change by way
            of imposition or increase of reserve requirements) in or in the
            interpretation of any treaty, law, rule, or regulation, or (2) the


                                     - 8 -

            compliance with any guideline or request from any central bank or
            other governmental authority or quasi-governmental authority
            exercising control over banks or financial institutions generally
            (whether or not having the force of law):

                              (1) Lender (or its applicable lending office)
                  shall be subject to any tax, duty, levy, cost or other charge
                  (except for (i) taxes on the overall net income or alternative
                  minimum taxable income of Lender or its applicable lending
                  office imposed by the jurisdiction in which Lender's principal
                  executive office or applicable lending office is organized,
                  located or is doing business and (ii) any branch profits taxes
                  imposed by the United States of America or any similar tax
                  imposed by any other jurisdiction and (iii) in the case of a
                  foreign lender, any withholding tax that is imposed on amounts
                  payable to such foreign lender) with respect to any LIBO Rate
                  Portions or its obligations to make LIBO Rate Portions, or the
                  recording, registration, notarization or other formalization
                  of the LIBO Rate Portions or the basis of taxation of payments
                  to Lender of the principal of or interest or commitment fees
                  or any amount payable on any LIBO Rate Portions or its
                  obligation to make LIBO Rate Portions shall change; or

                              (2) any reserve (including, without limitation,
                  any imposed by the Board of Governors of the Federal Reserve
                  System), special deposit or similar requirement against assets
                  of, deposits with or for the account of, or credit extended
                  by, Lender's applicable lending office shall be imposed on
                  Lender or its applicable lending office or the interbank LIBO
                  market,

            and as a result thereof there shall be any increase in the cost to
            Lender of agreeing to make or making, funding or maintaining LIBO
            Rate Portions, or there shall be a reduction in the amount received
            or receivable by Lender or its lending office in respect of such
            LIBO Rate Portions, then Borrower shall from time to time, upon
            written notice from and demand by Lender, pay to Lender, within five
            (5) Business Days after receipt of such notice, demand and
            appropriate proof of such cost, additional amounts sufficient to
            indemnify Lender against such increased cost or reduced amount. A
            certificate as to the amount of such increased cost or reduced
            amount, submitted to Borrower by Lender, shall except for manifest
            error, be final, conclusive and binding for all purposes. Any
            payments to be made by Borrower under Section 3.1(I)(A)(vi)(b),
            3.1(I)(A)(vi)(e) or 3.1(I)(A)(vi)(f) in respect of LIBO Rate
            Portions are to be without duplication.

                        (g) Calculation of all amounts payable to Lender under
            this Section 3.1(I)(A) shall be made as though Lender had actually
            funded its LIBO Rate Portion through the purchase of a LIBO deposit
            bearing interest at the LIBO Rate in an amount equal to the amount
            of that LIBO Rate Portion and having a maturity comparable to the
            relevant Interest Period and through the transfer of such LIBO
            deposit from an offshore office to a domestic office in the United
            States of America; provided, however, that Lender may --------
            ------- fund each of its LIBO Rate Portion in any manner it sees fit
            and the foregoing assumption shall be utilized only for the
            calculation of amounts payable under this Section 3.1(1)(A).

      B.    [RESERVED].

      II.   TERM A LOAN.

            Term Loan A shall bear interest (the "Term Loan A Interest Rate") at
            either a fixed rate per annum or a variable rate per annum, to be
            selected by Borrower no later than three (3) Business Days prior to
            the Closing. In the event Borrower elects that the Term Loan A
            Interest Rate throughout the term of the Loans shall be a fixed rate
            of interest, the Term Loan A Interest Rate shall be equal to the per
            annum rate offered on a five-year U.S. Treasury Note in effect as of
            three (3) Business Days prior to the Closing plus four and
            one-quarter percent (4.250%). The rate offered on a five-year U.S.
            Treasury Note shall be defined as the rate shown under the column
            heading "Ask Yld." for "Govt. Bonds & Notes" in the "Treasury Bonds,
            Notes & Bills" Section of The Wall Street Journal - Western Edition
            published on the third (3rd) Business Day prior to the Closing for
            the government bond or note with a maturity date in the same month
            and year as the Maturity Date, or, if there are more than one
            government bonds or notes with a maturity date in the


                                     - 9 -
<PAGE>   10
            same month and year as the Maturity Date, the highest of the rates
            shown in the "Ask Yld." column for any such bond or note, or, if
            there is no government bond or note with a maturity date in the same
            month and year as the Maturity Date, the average (rounded to the
            next highest basis point) of the rates shown in the "Ask Yld."
            column for the bonds or notes in the months preceding and following,
            the month in which the Maturity Date falls. In the event the
            Borrower elects that the Term Loan A Interest Rate throughout the
            term of the Loans shall be a variable rate of interest, (i) the Term
            Loan A Interest Rate shall be equal to the Base Rate plus one and
            one-quarter percent (1.250%), (ii) the interest rate chargeable
            shall be increased or decreased, as the case may be, without notice
            or demand of any kind, upon the announcement of any change in the
            Base Rate and (iii) each change in the Base Rate shall be effective
            hereunder on the first day following the announcement of such
            change, provided that, a cumulative change of less than one fourth
            of one percent (0.25%) shall not be considered. Regardless of
            whether a fixed or variable rate is chosen, interest on Term Loan A
            shall be calculated on the basis of a 360-day year and charged for
            the actual number of days elapsed.

      III.  CAPEX LOANS.

            The Capex Loans shall bear interest (the "Capex Loans Interest
            Rate") at either a fixed rate per annum or a variable rate per
            annum, to be selected by Borrower no later than three (3) Business
            Days prior to the Closing. In the event Borrower elects that the
            Capex Loans Interest Rate throughout the term of the Loans shall be
            a fixed rate of interest, the Capex Loans Interest Rate shall be
            equal to the per annum rate offered on a five-year U.S. Treasury
            Note in effect as of three (3) Business Days prior to the Closing
            plus four and one-quarter percent (4.250%). The rate offered on a
            five-year U.S. Treasury Note shall be defined as the rate shown
            under the column heading "Ask Yld." for "Govt. Bonds & Notes" in the
            "Treasury Bonds, Notes & Bills" Section of The Wall Street Journal -
            Western Edition published on the third (3rd) Business Day prior to
            the Closing for the government bond or note with a maturity date in
            the same month and year as the Maturity Date, or, if there are more
            than one government bonds or notes with a maturity date in the same
            month and year as the Maturity Date, the highest of the rates shown
            in the "Ask Yld." column for any such bond or note, or, if there is
            no government bond or note with a maturity date in the same month
            and year as the Maturity Date, the average (rounded to the next
            highest basis point) of the rates shown in the "Ask Yld." column for
            the bonds or notes in the months preceding and following the month
            in which the Maturity Date falls. In the event the Borrower elects
            that the Capex Loans Interest Rate throughout the term of the Loans
            shall be a variable rate of interest, (i) the Capex Loans Interest
            Rate shall be equal to the Base Rate plus one and one-quarter
