     This summary highlights information contained elsewhere in this prospectus.

carefully, including the "Risk Factors" section and the financial statements and

                                    ROCKFORD

     We are a leading designer, manufacturer and distributor of high-performance
car audio systems for the worldwide car audio aftermarket. Our car audio
products include technologically advanced amplifiers, speakers, source units and
accessories marketed under our Rockford Fosgate brand name. We also sell
professional audio products under our Hafler brand name.

     Rockford Fosgate is one of the world's premier high-performance car audio
brands. For nearly 20 years, Rockford Fosgate has been the brand of choice among
our core Generation Y consumers, particularly 16-24 year old males. We believe
our core consumers perceive our Rockford Fosgate brand as the "coolest" car
audio brand. 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 devote significant resources to enhancing 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 our 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 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.

     According to the Consumer Electronics Manufacturers' Association, 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 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. 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.

     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:

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

     - 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;

     - Develop a Second Brand.  We plan to develop, internally or through
       acquisitions, a second brand to be sold at lower price points than our
       current products. This strategy will help us enhance and expand our
       product offerings and increase our distribution capabilities;

     - 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 also
       believe that we have significant opportunities to increase our existing
       channels of distribution; and

     - 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 both Rockford Fosgate
       and Hafler in international markets.

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 three months ended March 31, 1998 and 1999. Also set
forth below is summary consolidated balance sheet data as at March 31, 1999, on
an actual, pro forma and pro forma as adjusted basis. The pro forma data gives
effect to the conversion of a $1,000,001 subordinated promissory note to a
related party into 316,498 shares of common stock on May 1, 1999 and the
conversion of $262,500 of the 8.5% convertible subordinated debentures into
117,500 shares of common stock to occur upon completion of this offering. The
pro forma as adjusted data gives effect to the sale by us of      shares in this
offering at an assumed initial public offering price of $     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."

               SPECIAL NOTE REGARDING 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 below, and
other factors noted throughout this prospectus, could cause our actual results
to differ significantly from those contained in any forward-looking statement.
We may not update or publicly release the results of these forward-looking
statements to reflect events or circumstances after the date of this prospectus.

                                  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.

WE ARE DEPENDENT ON DEMAND FOR CAR AUDIO PRODUCTS; THE CAR AUDIO INDUSTRY IS
RAPIDLY EVOLVING AND OUR PRODUCTS MAY NOT SATISFY SHIFTING CONSUMER DEMAND OR
COMPETE SUCCESSFULLY WITH COMPETITORS' PRODUCTS

     Our success will depend, in large part, on 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 would adversely affect our business, financial
condition and results of operations.

WE MUST ADAPT TO CHANGING DISTRIBUTION CHANNELS FOR CAR AUDIO PRODUCTS TO
MAINTAIN OUR MARKET SHARE AND BRAND IMAGE

     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

                                        8
<PAGE>   10

     - 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 would have a material adverse effect on our business, financial
condition and results of operations.

WE ARE HIGHLY DEPENDENT ON SALES OF OUR AMPLIFIER AND SPEAKER PRODUCTS

     Any decrease in demand for our amplifiers or speakers could have a material
adverse effect on our business, financial condition and results of operations.
These two product lines collectively accounted for approximately 78% of our
sales in calendar year 1996, 79% in 1997 and 82% in 1998. We expect these two
product lines to continue to account for a significant portion of our sales in
the foreseeable future.

WE RELY HEAVILY UPON BEST BUY AS A SIGNIFICANT CUSTOMER; OUR RELATIONSHIP IS
VERY RECENT AND WE COULD LOSE THIS CUSTOMER AT ANY TIME

     The loss of Best Buy as a customer or significant fluctuations or
reductions in its purchases of our products would have a material adverse effect
on our business, financial condition and results of operations. Including Best
Buy's $4.4 million initial purchase of our products to stock its distribution
channel, Best Buy accounted for 25.6% of our sales in the three months ended
March 31, 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 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 NOT BE 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

     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.

                                        9
<PAGE>   11

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:

     - consumer demand for, and acceptance of, our products;

     - the level of product, price and dealer competition;

     - general economic conditions, both in the U.S. and internationally;

     - 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;

     - our successes or failures in expanding our customer base and distribution
       channels;

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

     - capacity and supply constraints or difficulties;

     - timing of marketing programs;

     - changes in foreign currency exchange rates; and

     - risks associated with potential acquisitions.

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

CAR AUDIO SALES ARE HIGHLY INFLUENCED BY CONSUMER DEMAND FOR DISCRETIONARY ITEMS

     A recession in the general economy or a general decline in consumer
spending would likely have a material adverse effect on our business, financial
condition and results of operations because car audio purchases are highly
discretionary. 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.

WE MAY BE UNABLE TO EXECUTE SUCCESSFULLY OUR GROWTH STRATEGY

     If we do not execute our business plan, our business may erode. Our
business plan contemplates that we will:

     - promote our unique brand image;

     - introduce new and innovative products;

     - develop a second brand;

                                       10
<PAGE>   12

     - expand channels of distribution, such as Best Buy; and

     - capitalize on international opportunities.

We cannot be certain that we will achieve these 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.

WE MAY BE UNABLE TO EFFECTIVELY MANAGE OUR GROWTH

     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.

Our inability to manage growth effectively could have a material adverse effect
on our business, financial condition and results of operations.

WE MUST CONTINUE TO DEVELOP, INTRODUCE AND ACHIEVE MARKET ACCEPTANCE OF NEW AND
ENHANCED PRODUCTS

     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.

WE MUST MANAGE OUR PRODUCT INVENTORY IN PROPORTION TO DEMAND

     Our success depends in large part on our ability to manage our inventory of
products in proportion to demand. 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 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.

                                       11
<PAGE>   13

OUR INTERNATIONAL OPERATIONS PRESENT SPECIAL RISKS

     Our international business, as well as the businesses of our distributors
and suppliers, are subject to the risks inherent in international trade,
including risks resulting from:

     - 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.

Changes in these and other factors 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 10.6% of total sales for 1998 and 5.5%
of sales for the three months ended March 31, 1999.

     International customers accounted for 28.0% of our sales in calendar year
1996, 26.1% in 1997 and 19.7% in 1998. To continue our growth and profitability,
we will need to expand our sales in international markets. We primarily rely on
distributors, who purchase and resell our products, for a substantial portion of
our international sales. Each distributor is responsible for one or more
particular countries. 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.

     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. We believe
this strategy will increase our gross margins while lowering the cost of our
products to retailers and consumers. To the extent we extend this strategy into
additional markets, we would incur higher operating expenses, including sales
commissions, warranty costs and customer service expenses, and would have higher
working capital requirements and risks because of increased inventory and
accounts receivable.

     We may be affected by foreign currency exchange rate fluctuations. 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
                                       12
<PAGE>   14

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.

WE DEPEND ON A FEW KEY SUPPLIERS

     We have not experienced significant supply restrictions in the past, but
our manufacturing processes recently have become more dependent on
"just-in-time" suppliers who are globally sourced. Accordingly, our exposure to
supply restrictions has increased. 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. Despite the precautions
we take, the components and materials we receive from third-party suppliers may
not always conform to our quality standards. 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.

     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 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 maintain a $1.0 million key-person life insurance policy covering
Mr. Suttle. 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 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 business, financial condition and results of operations could suffer.

WE MAY BE UNABLE TO ENFORCE OR DEFEND OUR OWNERSHIP AND USE OF OUR INTELLECTUAL
PROPERTY

     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. We generally control access to and distribution of our
proprietary information. Despite our efforts to protect our proprietary
information, third parties may obtain, disclose or use our proprietary
information without our authorization. If they do, their actions could have a
material adverse effect on our business, financial condition and results of
operations.

     From time to time, third parties have alleged that we infringe their
proprietary rights. In particular, we have exchanged correspondence with a third
party regarding our alleged infringement of patents held by that party. We
believe that our products do not infringe any valid patents cited in the
correspondence. Nonetheless, these claims or similar future claims

                                       13
<PAGE>   15

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. Any of these developments could have a
material adverse effect on our business, financial condition and results of
operations.

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.

OUR STOCK PRICE MAY BE HIGHLY VOLATILE

     The market price of our common stock is likely to be highly volatile. You
may not be able to resell your shares during or following periods of volatility
because of the market's adverse reaction to such volatility. Factors that could
cause market volatility may include:

     - actual or anticipated variations in our quarterly operating results;

     - changes in market expectations or in analysts' earnings estimates;

     - changes in investor confidence in us or our industry;

     - changes in conditions in the car audio industry;

     - new products or technological innovations introduced by us or our
       competitors;

     - announcements by us or our competitors of significant acquisitions or
       strategic relationships;

     - additions or departures of our key personnel; and

     - general economic conditions or stock market volatility.

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
                                       14

problem, if one develops, could result in an interruption in, or a failure of,
certain 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

     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      % 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.

YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION

     If you purchase shares in this offering, you will incur immediate and
substantial dilution in pro forma net tangible book value per share of $     .
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      % of the total amount paid to us for our common
stock, but will own only      % 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. 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 such sales could occur. These sales also might
make it 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

     Provisions of our articles of incorporation and bylaws and Arizona law
could discourage potential acquirors from attempting to acquire us. This could
deprive our shareholders of opportunities to sell our stock at above-market
prices typical of such acquisitions.

                                USE OF PROCEEDS

     The net proceeds to us from the sale of the                shares of common
stock offered by us hereby are estimated to be $     million, or $     million
if the underwriters' over-allotment option is exercised in full, in each case
assuming an initial public offering price of $     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 to repay our credit facility, which had an
outstanding balance of $13.4 million as at March 31, 1999, and for working
capital and other general corporate purposes, including new product development
and marketing expansion. We may also use a portion of the net proceeds to
acquire or invest in complementary businesses, products or technologies. 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 March 31, 1999, the credit facility had a combined
interest rate of 8.35% per annum. The credit facility matures on June 20, 2001.

                                 CAPITALIZATION

     The following table sets forth our capitalization as at March 31, 1999, on
an actual, pro forma and pro forma as adjusted basis. The pro forma data gives
effect to the conversion of a $1,000,001 subordinated promissory note to a
related party into 316,498 shares of common stock on May 1, 1999, the increase
in our authorized common stock to 20,000,000 shares on May 17, 1999 and the
conversion of $262,500 of the 8.5% convertible subordinated debentures into
117,500 shares of common stock to occur upon completion of this offering. The
pro forma as adjusted data gives effect to the sale by us of
shares in this offering at an assumed initial public offering price of $     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.

                                    DILUTION

     Our pro forma net tangible book value as at March 31, 1999, after giving
effect to the conversion of a $1,000,001 subordinated promissory note to a
related party into 316,498 shares of common stock on May 1, 1999 and the
conversion of $262,500 of the 8.5% convertible subordinated debentures into
117,500 shares of common stock to occur upon completion of this offering, was
$7.9 million, or $1.50 per share of common stock. Pro forma net tangible book
value is equal to total pro forma tangible assets less total liabilities and
minority interest. 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. After giving effect to the sale by us of
shares in this offering at an assumed initial public offering price of $     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, our pro forma net
tangible book value as at March 31, 1999 would have been $          million, or
$     per share. This represents an immediate increase in pro forma tangible
book value of $     per share to existing shareholders and an immediate dilution
of $     per share to new investors. The following table illustrates this per
share dilution:

     The foregoing discussion and table assume no exercise of outstanding
debentures, options and warrants to purchase our common stock other than the
conversion of $262,500 of the 8.5% convertible subordinated debentures to occur
upon completion of this offering. As at May 15, 1999, there were issuable:

     - 327,787 shares of common stock issuable upon exercise of the 8.5%
       convertible subordinated debentures, assuming conversion of 117,500
       shares in this offering;

     - 2,207,858 shares of common stock issuable upon exercise of outstanding
       options, with a weighted average exercise price of $3.06 per share;

     - 70,500 shares of common stock issuable upon exercise of outstanding
       options, with an exercise price of the per share price of this offering;

     - 108,302 shares of common stock issuable upon exercise of outstanding
       warrants, with a weighted average exercise price of $1.35 per share;

                                       18

     - 355,404 shares of common stock reserved for future issuance under our
       1994 and 1997 stock option plans; and

     - 394,800 shares of common stock reserved 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

     We are a leading designer, manufacturer and distributor of high-performance
car audio systems for the worldwide car audio aftermarket. 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;

     - substantially increased new product introductions without a significant
       increase in design staff;

     - 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 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.

     During the last three years, a substantial portion of our sales were
derived from customers located outside of the U.S., and we believe that our
continued growth and profitability will require further expansion in
international markets.

     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 25.6% of our sales for the three months ended March 31,
1999. We anticipate that Best Buy will continue to account for a significant
portion of our sales for the foreseeable future.

</TABLE>

     Cost of goods sold primarily consists of raw materials, direct labor and
manufacturing costs associated with production of our products as well as
warranty, warehousing and customer service expenses. Sales and marketing
expenses primarily consist of salaries, sales commissions and costs of
advertising, trade shows, distributor and sales representative

                                       22

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 and development expenses primarily consist of salaries
associated with our research and development personnel.

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

THREE MONTHS ENDED MARCH 31, 1999 COMPARED TO THREE MONTHS ENDED MARCH 31, 1998

     Sales.  Sales increased by $11.3 million, or 54.1%, to $32.0 million for
the three months ended March 31, 1999 from $20.8 million for the three months
ended March 31, 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 $8.2
million, or 25.6%, of our sales for the three months ended March 31, 1999. In
addition, sales to car audio specialty dealers increased by $1.9 million, or
10.8%, to $19.6 million for the three months ended March 31, 1999 from $17.7
million for the three months ended March 31, 1998.

     U.S. sales increased by $11.1 million, or 67.5%, to $27.6 million for the
three months ended March 31, 1999 from $16.5 million for the three months ended
March 31, 1998. International sales increased by $0.1 million, or 2.5%, to $4.4
million for the three months ended March 31, 1999 from $4.3 million for the
three months ended March 31, 1998. A decrease in sales to certain countries in
Latin America was offset by increased sales in other international regions.

     Cost of Goods Sold.  Cost of goods sold increased by $6.4 million, or
48.8%, to $19.6 million for the three months ended March 31, 1999 from $13.1
million for the three months ended March 31, 1998. Substantially all of the
increase was due to increased sales. As a percent of sales, cost of goods sold
decreased to 61.1% for the three months ended March 31, 1999 from 63.3% for the
three months ended March 31, 1998. The primary reasons for the decrease as a
percent of sales included (1) improvement in global sourcing of raw materials,
(2) leveraging of fixed overhead due to increased production volume, (3) ongoing
production process improvements and (4) shifting of sales away from lower margin
source units.

     Sales and Marketing Expenses.  Sales and marketing expenses increased by
$1.5 million, or 35.5%, to $5.6 million for the three months ended March 31,
1999 from $4.1 million for the three months ended March 31, 1998. 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 decreased to 17.5% for
the three months ended March 31, 1999 from 20.0% for the three months ended
March 31, 1998. The decrease as a percent of sales was primarily due to the
fixed nature of a portion of these expenses which do not fluctuate with sales.

     General and Administrative Expenses.  General and administrative expenses
increased by $0.7 million, or 31.8%, to $3.0 million for the three months ended
March 31, 1999 from $2.3 million for the three months ended March 31, 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 9.4% for the three months ended March 31, 1999 from 11.0%
for the three months ended March 31, 1998. The decrease as a percent of sales
was primarily due to the fixed nature of a portion of these expenses which do
not fluctuate with sales.

     Research and Development Expenses.  Research and development expenses
increased by $0.1 million, or 24.0%, to $0.5 million for the three months ended
March 31, 1999 from $0.4 million for the three months ended March 31, 1998. As a
percent of sales, these expenses

                                       23
<PAGE>   25

decreased to 1.6% for the three months ended March 31, 1999 from 1.9% for the
three months ended March 31, 1998.

     Operating Income.  Operating income increased by $2.5 million, or 321.3%,
to $3.3 million for the three months ended March 31, 1999 from $0.8 million for
the three months ended March 31, 1998. This increase was primarily attributable
to our initial sales to Best Buy. As a percent of sales, operating income
increased to 10.4% for the three months ending March 31, 1999 from 3.8% for the
three months ended March 31, 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 $0.4 million for
the three months ended March 31, 1999 and for the three months ended March 31,
1998. Interest expense was similar for both periods due to relatively constant
levels of debt and interest rates.

     Income Tax Expense (Benefit).  Income tax expense increased by $0.9 million
to $1.1 million for the three months ended March 31, 1999 from $0.2 million for
the three months ended March 31, 1998. The effective income tax rates were 37.8%
for the three months ended March 31, 1999 and 40.5% for the three months ended
March 31, 1998. The primary reason for the higher effective tax rate for the
three months ended March 31, 1998 was the impact of relatively fixed,
non-deductible items for income tax accounting purposes on a much lower amount
of net income.

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

     Sales.  Sales increased by $0.2 million, or 0.3%, to $89.0 million for 1998
from $88.8 million for 1997. U.S. sales increased by $5.8 million, or 8.9%, to
$71.4 million for 1998 from $65.6 million for 1997. International sales
decreased by $5.6 million, or 24.2%, to $17.6 million for 1998 from $23.2
million for 1997. Increased sales in the U.S. were offset by lower sales in
Latin America and Asia due to economic instability in those regions.

     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 62.0% for 1998 from 64.6% for 1997. The primary
reasons for the decrease as a percent of sales included (1) improvement in
global sourcing of raw materials, (2) leveraging of fixed overhead due to
increased production volume as we prepared for initial shipments to Best Buy,
(3) ongoing production process improvements and (4) shifting of sales away from
lower margin source units.

     Sales and Marketing Expenses.  Sales and marketing expenses increased by
$0.4 million, or 2.3%, to $16.3 million for 1998 from $15.9 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
18.2% for 1998 from 17.9% 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. As a percent of sales, these expenses increased to 11.5% for 1998
from 10.5% 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

                                       24
<PAGE>   26

6.2% for 1998 from 5.2% 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 $6.1 million, or 7.3%, to $88.8 million for 1997
from $82.7 million for 1996. Substantially all of the increase in sales was due
to increased sales. U.S. sales increased by $6.0 million, or 10.1%, to $65.6
million for 1997 from $59.6 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 customers in Europe.

     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 64.6% for 1997 from 69.0% for 1996. The primary reasons for the
decrease as a percent of sales included (1) improvement in global sourcing of
raw materials, (2) leveraging of fixed overhead due to increased production
volume, (3) ongoing production process improvements and (4) shifting of sales
away from lower margin source units.

     Sales and Marketing Expense.  Sales and marketing expenses increased by
$0.5 million, or 3.1%, to $15.9 million for 1997 from $15.4 million for 1996.
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 decreased to
17.9% for 1997 from 18.6% 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 10.5% for 1997 from 9.9% 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 1.6% 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 5.2% 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
                                       25
<PAGE>   27

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 25.6% of our sales in the three
months ended March 31, 1999.

     The following tables set forth selected consolidated quarterly statements
of operations data that were derived from unaudited financial statements for
each of the nine quarters ended March 31, 1999, as well as such 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 $15.6 million at March 31, 1999, compared with $13.5 million at
December 31, 1998. At March 31, 1999, we maintained minimal cash and cash
equivalent balances.

     We currently have a $20.0 million credit facility which 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 March 31,
1999, the credit facility had a combined interest rate of 8.35% per annum. The
credit facility matures on June 20, 2001.

     We also have a $2.0 million capital lease credit facility under which
leases can be funded up until September 30, 1999. We use the capital lease
credit facility for the purchase of capital equipment under agreements
structured as three-year capital lease obligations. As at March 31, 1999, the
capital lease credit facility had an outstanding balance of $1.1 million.

     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 $0.8 million for the three months ended March
31, 1999 and ($0.3) million for the three months ended March 31, 1998. In recent
periods, our working capital requirements have offset cash provided by net
income plus depreciation, resulting in low cash flows from operating activities.
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 $0.7 million for the three months ended March 31, 1999 and $0.3
million for the three months ended March 31, 1998. Net cash used in investing
activities was primarily related to purchases of property and equipment.

     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
(used in) financing activities was ($0.1) million for the three months ended
March 31, 1999 and $0.7 million for the three months ended March 31, 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 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

                                       28

can be no assurance that such 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.  To date, we have completed an
inventory, compliance analysis and testing of business critical financial,
information and operational systems, including manufacturing control systems.
Testing of business critical application programs began in the first quarter of
1994, and was completed during the second quarter of 1997. Remedial activities
vary by department. However, on average, remedial activities are approximately
95% complete.

     Third Party Year 2000 Compliance.  We are surveying Year 2000 compliance of
our key financial institutions, suppliers, vendors, research partners,
governmental entities and customers. If any of these third parties experience
Year 2000 failures, their failures could impair our ability to process
transactions, manufacture products or engage in similar normal business
activities. While some of these risks are outside our control, we have
instituted programs, including internal records reviews and use of external
questionnaires, to identify key third parties, assess their level of Year 2000
compliance, update contracts and address any non-compliance issues. We have
completed approximately 85% of these activities with the remaining activities
scheduled for completion by the end of the third quarter of 1999.

     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. A substantial portion of
such costs has 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 risk 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
such compliance problems on a timely basis could result in lost sales,
                                       29
<PAGE>   31

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.

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

                                    BUSINESS

OUR BUSINESS

     We are a leading designer, manufacturer and distributor of high-performance
car audio systems for the worldwide car audio aftermarket. Our car audio
products include technologically advanced amplifiers, speakers, source units and
accessories marketed under our Rockford Fosgate brand name. We also sell
professional audio products under our Hafler brand name.

     Rockford Fosgate is one of the world's premier high-performance car audio
brands. For nearly 20 years, Rockford Fosgate has been the brand of choice among
our core Generation Y consumers, particularly 16-24 year old males. We believe
our core consumers perceive our Rockford Fosgate brand as the "coolest" car
audio brand. 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 devote significant resources to enhancing 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 our 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 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

     According to the Consumer Electronics Manufacturers' Association, CEMA,
total worldwide factory sales of car audio products were approximately $14.7
billion in 1998, of which $6.3 billion represented aftermarket sales. Also,
according to CEMA, 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.

                                       31
<PAGE>   33

     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.

     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.

     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.

                                       32

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:

     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 brand 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.

     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.

     Develop a Second Brand.  In response to requests from our retailers and
international distributors, we intend to develop, internally or through
acquisition, a second brand to be sold at lower 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. We believe the addition of a second brand
will help us enhance and expand our product offerings and increase our
distribution capabilities.

     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 committed
substantial 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 leading 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.

     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 both Rockford Fosgate 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
                                       33
<PAGE>   35

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.

OUR PRODUCTS

     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:

<TABLE>
<S>                       <C>
Amplifiers..............  Two channel amplifiers; multi-channel amplifiers; mono
                          (single channel) amplifiers; signal processors
Speakers................  Subwoofers; woofers; mid-range separates; full range or
                          coaxial speakers; speaker enclosures; tweeters
Source Units............  AM/FM/CD players; compact disc changers
Accessories.............  Amplifier installation kits; power, ground and speaker wire;
                          RCA cables; connectors; adaptors; stiffening caps;
                          miscellaneous electrical components; installation
                          accessories; Punch Sport brand promotional materials and
                          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 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, Innovations awards at the
Consumer Electronics Shows and European Car Audio Press awards.

                                       34

     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 have won awards from Pro Audio Review, Mix Magazine and Canadian
Music-Music Week Magazine, as well as the EQ Award and Electronic Musician
Editor's Choice Award.

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 efforts rely on concurrent engineering processes
which involve a coordinated effort across multiple areas of our company. As at
March 31, 1999, our research and development staff consisted of ten design
engineers, as well as other support staff, dedicated to project development and
who coordinate their efforts with (1) our sales group to identify features
consistent with market requirements and our brand image, (2) our manufacturing
staff to develop and build products more efficiently, (3) our product support
staff to identify weaknesses in our existing products and to help re-design them
and (4) 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 our efforts and our new sourcing and manufacturing
strategies, 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 or reengineer
approximately one-third of our product line annually. In 1998, more than 60% of
our sales were generated from new or reengineered products.

     We devote substantial resources to creating a "technology shelf" that we
can use to develop next-generation products and features. Our technology shelf
provides a 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 our
technology shelf include powered speakers, remote bass and speaker controls,
active cross-overs, circuit designs such as class BD amplifiers, mechanical
components, cosmetics and materials improvements, 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.

                                       35
<PAGE>   37

     Our sales and marketing activities focus on:

     - 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.

     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.

     CAR AUDIO DISTRIBUTION

     We currently sell our 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.

     Our U.S. distribution system is composed of specialty dealers, audio/video
retailers, consumer electronics chains and catalog merchants. 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 leveraging off 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.
                                       36
<PAGE>   38

     During 1999, we initiated a program to convert selected foreign markets to
a "one-step" distribution system by switching to independent sales
representatives, allowing us to sell directly to retailers. We expect this
transition to substantially increase our penetration in these markets by
lowering our distribution costs and reducing prices to the consumer. 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.

     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 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. Third parties manufacture our source
units, coaxial 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. We use advanced surface mount
technology in our electronics manufacturing. 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

                                       37
<PAGE>   39

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.

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 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:  Lightning Audio, Monster Cable, Phoenix Gold and
       Stinger; and

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

     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

     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.

     We have a fully integrated system based on a Novell network, Oracle
applications and databases, Microsoft Office applications and a Cisco
infrastructure. Our business applications are flexible and designed to enhance
our productivity. Applications are distributed throughout the organization, from
manufacturing to order entry and financial reporting.

     We have implemented Web-based systems to 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 expend substantial resources to maintain and protect 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);

     - Hafler(R); and

     - Our "Diamond R" logo.

EMPLOYEES

     As at March 31, 1999, we had 422 total employees. At that date, in the
U.S., 283 were engaged in manufacturing, 33 in research and development, 40 in
sales and marketing and 49 in administration. We also had 17 employees working
outside of the U.S. in various functions. We have never had a work stoppage and
none of our employees are unionized. We believe our employee relations are good.

(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 sets forth 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 such 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;

     - 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 2,350,000 shares for issuance under both plans.
As at March 31, 1999, we had:

     - issued 21,738 shares under the plans;

     - outstanding options to purchase 1,972,858 shares under the plans at a
       weighted average exercise price of $3.26 per share; and

     - 355,404 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

                                       45

being exercised. Under the 1997 plan, the maximum number of shares any
individual may receive during a calendar year is 470,000 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.

OTHER OPTIONS

     We also granted options to purchase 235,000 shares of our common stock to
Grisanti, Galef & Goldress before the adoption of the 1994 plan at an exercise
price of $4.89 per share which we agreed to reduce to $1.38 per share in October
1994. This option expires on August 1, 2002.

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 394,800 shares of our
common stock are reserved for issuance under the plan, which will become
effective on July 1, 1999.

     The plan is intended to qualify under Section 423 of the Internal Revenue
Code and provides for overlapping 24-month offering periods. Each offering
period includes four purchase periods. The offering periods generally start on
the first trading day on or immediately preceding July 1 and January 1 of each
year, with the first offering period commencing on July 1, 1999 and ending on
the last trading day on or immediately preceding July 1, 2001.

                                       46
<PAGE>   48

     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: (1) immediately after the grant, owns shares
controlling 5% or more of the total combined voting power of our shares or (2)
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 4,700 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 purchase period, whichever is less. In the event the fair market
value at the end of a purchase period is less than the fair market value at the
beginning of the offering period, the employees will be withdrawn from the
current offering period following exercise and automatically re-enrolled in a
new offering period. The new offering period will use the lower fair market
value as of the first date of the new offering period to determine the purchase
price for future purchase periods. Employees may end their participation at any
time during a purchase 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 such 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.

                              CERTAIN TRANSACTIONS

GRISANTI, GALEF & GOLDRESS CONSULTING AGREEMENT

     We initially retained Grisanti, Galef & Goldress to provide Mr. Suttle's
consulting services to us under a February 1992 letter agreement. Effective on
August 1, 1992, we named Mr. Suttle our President and Chief Executive Officer
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
235,000 shares of our common stock at an exercise price of $4.89 per share. In
October 1994, we agreed to reduce the exercise price of the option to $1.38 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 235,000-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 23,500 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 869,500 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. 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 316,498 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 $3.16 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 316,498 shares on May 1, 1999.

                       PRINCIPAL AND SELLING SHAREHOLDERS

     This table sets forth certain information with respect to the beneficial
ownership of our outstanding common stock as at May 15, 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
5,255,624 shares of common stock outstanding as at May 15, 1999, and assuming
the conversion of $262,500 of the 8.5% convertible subordinated debentures into
117,500 shares to occur upon completion of this offering, and assumes 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 May 17, 1999, we increased our authorized capital stock from
10,000,000 to 20,000,000 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 ratably dividends as may be declared by the board
of directors out of funds legally available therefore. In the event of our
liquidation, dissolution or winding up, holders of common stock are entitled to
share ratably 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 May 15, 1999, assuming the conversion of $262,500 of the 8.5%
convertible subordinated debentures into 117,500 shares upon completion of this
offering, there were outstanding 5,255,624 shares of common stock, options to
purchase 2,207,858 shares of common stock, warrants to purchase 108,302 shares
of common stock and debentures convertible into 327,787 shares of common stock.
Upon completion of this offering,             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
May 15, 1999.

WARRANTS

     As of the date of this prospectus, warrants to purchase 84,802 shares of
common stock at an exercise price of $0.85 per share and warrants to purchase
23,500 shares of common stock at an exercise price of $3.16 per share were
outstanding. The common stock issuable upon exercise of the 84,802 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 445,287
shares of our common stock at a conversion price of $2.23 per share. The common
stock issuable upon exercise of these debentures is subject to registration
rights, which are described below.

REGISTRATION RIGHTS

     The holders of approximately 84,802 shares of common stock, issuable upon
exercise of outstanding warrants, have registration rights for the shares of
common stock issuable upon exercise of the warrants. Their rights are subject to
customary conditions. They include "piggyback" registration rights in connection
with 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

                                       53
<PAGE>   55

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

     The holders of approximately 445,287 shares of common stock, issuable upon
conversion of the 8.5% convertible subordinated debentures, have registration
rights for the shares of common stock issuable upon conversion of their
debentures. Their rights are subject to customary conditions. They include
"piggyback" registration rights in connection with 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 debentures or of
common stock issued upon conversion of the debentures must request registration
and the proposed offering must be expected to raise proceeds of at least $15.0
million.

ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF OUR ARTICLES OF INCORPORATION
AND BYLAWS

     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 person
nominated. Together, these restrictions may limit proxy contests seeking to
control us by (1) limiting shareholders' ability to call a special shareholders
meeting, (2) making shareholder action by written consent impossible as a
practical matter, and (3) giving the board of directors advance notice of
hostile annual meeting proposals.
                                       54

     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 certain types of 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.

     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.

LISTING

     We will apply for quotation of our common stock on The Nasdaq National
Market under the symbol "ROFO."

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is First Chicago
Trust Company of New York and its address is 525 Washington Boulevard, Jersey
City, New Jersey 07310.

                        SHARES ELIGIBLE FOR FUTURE SALE

     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.

     After this offering, we will have        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 $262,500 of the 8.5%
convertible subordinated debentures into 117,500 shares upon completion of this
offering. Of these shares, the           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           outstanding shares of common stock will be "restricted
securities" under Rule 144.

     Our directors, executive officers and other shareholders, holding
          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
Needham & Company, Inc. 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:

</TABLE>

     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

                                       56
<PAGE>   58

the Securities Exchange Commission. 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.

     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.

     The underwriter named below has 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 indicated below opposite their
respective names at the initial public offering price less the underwriting
discounts and commissions set forth on the cover page of this prospectus. The
underwriting agreement provides that the obligations of the underwriters to pay
for and accept delivery of such shares are subject to certain conditions
precedent, and that the underwriters are committed to purchase all such shares,
if any are purchased.

     The representatives have advised us that the underwriters initially propose
to offer the shares of common stock to the public on the terms set forth on the
cover page of this prospectus. The underwriters may allow to selected dealers
(who may include the underwriters) a concession of not more than $     per
share, and the underwriters may allow, and such dealers may reallow, a
concession of not more than $     per share to certain other dealers. After this
offering, the public offering price and other selling terms may be changed by
the representatives. We estimate that the total offering expenses payable by us,
other than underwriting discounts and commissions, will be $            .

     We have granted an option to the underwriters, exercisable during the
30-day period after the date of this prospectus, to purchase up to
additional shares of common stock at the same price per share as the initial
          shares to be purchased by the underwriters. To the extent that the
underwriters exercise this option, each of the underwriters will be committed,
subject to certain conditions, to purchase such additional shares in
approximately the same proportion as set forth in the above table and we will be
obligated to sell such shares to the underwriters. The underwriters may purchase
such shares only to cover over-allotments made in connection with this offering.
If purchased, the underwriters will offer such additional shares on the same
terms as those on which the initial shares are being offered.

     Our executive officers, directors and other shareholders, beneficially
holding in the aggregate           shares of common stock after this offering,
have agreed that, for a period of 180 days after the date of this prospectus,
they will not, without the prior written consent of Needham & Company, Inc.,
directly or indirectly sell, offer to sell or otherwise dispose of any such
shares of common stock or any right to acquire such shares. In addition, we have
agreed that, for a period of 180 days after the date of this prospectus, we will
not, without the prior written consent of Needham & Company, Inc., issue, offer,
sell, grant options to purchase or otherwise dispose of any of our equity
securities or any other securities convertible into or exchangeable for the
common stock or other equity security, other than the grant of options to
purchase common stock or the issuance of shares of common stock under our stock
option and stock purchase plans, and the issuance of shares of common stock
pursuant to the exercise of outstanding options, warrants and conversion of
debentures.

     The representatives of the underwriters have informed us that they do not
expect sales to accounts over which the underwriters have discretionary
authority to exceed five percent of the total number of shares of common stock
offered by them.

     The underwriting agreement provides that we will indemnify the several
underwriters against certain liabilities, including civil liabilities under the
Securities Act of 1933, or will

                                       58
<PAGE>   60

contribute to payments the underwriters may be required to make arising from
these types of liabilities.

     In connection with this offering, certain underwriters and selling group
members (if any) or their respective affiliates who are qualifying registered
market makers on The Nasdaq National Market may engage in passive market making
transactions in our common stock on The Nasdaq National Market in accordance
with Regulation M under the Securities Exchange Act of 1934 during the two
business day period before commencement of offers or sales of the common stock
offered hereby. The passive market making transactions must comply with
applicable volume and price limits and be identified as such. In general, a
passive market maker may display its bid at a price not in excess of the highest
independent bid for the security; if all independent bids are lowered below the
passive market maker's bid, however, such bid must then be lowered when certain
purchase limits are exceeded.

     The following table summarizes the compensation to be paid to the
underwriters by us and the selling shareholders and the expenses payable by us
and the selling shareholders.

     Prior to this offering, there has been no public market for our common
stock. Consequently, the public offering price for the common stock offered by
this prospectus will be determined through negotiations among us, the selling
shareholders and the representatives of the underwriters. Among the factors to
be considered in such negotiations will be prevailing market conditions, our
financial results, market valuations of other companies that we and the
representatives believe to be comparable to us, estimates of our business
potential, the present state of our development and other factors deemed
relevant.

                                 LEGAL MATTERS

by Steptoe & Johnson LLP, Phoenix, Arizona. Certain legal matters in connection
with this offering will be passed upon for the underwriters by Brobeck, Phleger

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

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 three months ended
                     March 31, 1998 and 1999 is unaudited)

1.  ACCOUNTING POLICIES

  Organization and Description of Business

     Rockford Corporation and subsidiaries ("Rockford") is a leading 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.

  Interim Financial Information

     The consolidated financial statements as of March 31, 1999 and for the
three months ended March 31, 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 three months ended March 31, 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.

  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

                     ROCKFORD CORPORATION AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                  (The information for the three months ended
                     March 31, 1998 and 1999 is unaudited)

and March 31, 1999, net accounts receivable includes approximately $3,213,000,
$2,958,000 and $4,302,000, 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 March 31, 1999 approximately $162,000,
$262,000 and $395,000, 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.

  Research and Development

     During the year ended September 30, 1996, the three months ended December
31, 1996, and the years ended December 31, 1997 and 1998, research and
development expenses of approximately $1,448,000, $292,000, $1,576,000 and
$1,876,000, respectively, were charged to expense as incurred.

  Advertising

     Rockford expenses advertising as incurred. Advertising expenses for the
year ended September 30, 1996, the three months ended December 31, 1996, and the
years ended December 31, 1997 and 1998 were approximately $1,189,000, $313,000,
$1,008,000 and $1,201,000, respectively.

  Income Taxes

     Rockford accounts for income taxes under the provisions of Statement of
Financial Accounting Standard ("SFAS") No. 109, Accounting for Income Taxes.
Under this method, 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.

  Net Income per Common Share

     Rockford reports net income per common share in accordance with Financial
Accounting Standards Board ("FASB") Statement No. 128, Earnings Per Share.
Diluted net income per share includes the dilutive effects of options, warrants
and convertible securities.

                     March 31, 1998 and 1999 is unaudited)

  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. Statement of operations 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 shareholders' equity. The effect on the statement of operations of
transaction gains and losses is insignificant.

  Stock Based Compensation

     Rockford grants stock options for a fixed number of shares to employees
with an exercise price equal to the fair value of the shares at date of grant.
Rockford has adopted the disclosure-only provisions of Statement of Financial
Accounting Standards No. 123, Accounting for Stock-Based Compensation and
accordingly, recognizes no compensation expense for the employee stock option
grants. Stock option grants to non-employees are charged to expense based upon
the fair value of the options granted.

  Use of Estimates

     The preparation of consolidated financial statements in conformity with
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

     Effective January 1, 1998, Rockford adopted SFAS No. 130, Reporting
Comprehensive Income. In adopting the new requirements for calculating income,
items of other comprehensive income have been presented in the equity section of
the statement of shareholders' equity.

  Segments of an Enterprise and Related Information

     Effective January 1, 1998, Rockford adopted SFAS No. 131, Disclosures about
Segments of an Enterprise and Related Information. SFAS No. 131 superseded FASB
Statement No. 14, Financial Reporting for Segments of a Business Enterprise.
SFAS No. 131 establishes standards for the way that business enterprises report
information about operating segments in annual financial statements and requires
that those enterprises report selected information about operating segments in
interim financial reports. SFAS No. 131 also establishes standards for related
disclosures about products and services, geographic areas and major customers.

  Reclassifications

     Certain reclassifications have been made to the prior period consolidated
financial statements to conform to the 1998 presentation.

     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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                  (The information for the three months ended
                     March 31, 1998 and 1999 is unaudited)

purchase 235,000 shares of its authorized but unissued common stock at a price
of $1.38 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 2,350,000 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:

Dividend yield...........................................  0 percent

9.  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.

10.  BENEFIT PLAN

     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

11.  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
professional audio line was not significant and, accordingly, no additional
disclosures of revenue information about products are required. Below is
geographic information for revenues of Rockford:

(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 three months ended March 31, 1999
in which sales to one customer accounted for 25.6 percent of that period's net
sales. Rockford's long-lived assets outside of the United States are not
significant.

12.  SUBSEQUENT EVENTS

     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 May 1, 1999, the $1,000,001 promissory note due to a related party was
converted into 316,498 shares of Rockford's common stock.

     On May 17, 1999, the shareholders approved the adoption of the 1999
Employee Stock Purchase Plan to be effective July 1, 1999. Under the plan,
394,800 shares have been reserved for issuance.

     On May 17, 1999, the shareholders approved an increase in the number of
authorized common shares to 20,000,000.

     Effective             , 1999, Rockford executed a 4.7-for-1 common stock
split. All share information in the financial statements has been restated to
reflect the effect of the stock split.

Text in upper center: 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. 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. This unique strategy allows the
Hafler brand to take advantage of Rockford Corporation's world class product
development process and manufacturing muscle.

Now, those opinionated human filters that wedge themselves between musicians,
and listeners are lining up. Lining up at retailers around the world and
hitting the web to demand the finest in sound quality and technology.
Everything that goes into the design and excitement of Hafler challenges the
music professional to come to www.hafler.com.

* To be filed by amendment.

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.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES

     Since May 1, 1996, we have issued and sold or otherwise transferred the
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.

          1.  In 1996 and 1997, we issued 21,738 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 316,498 shares of
     Common Stock.

          3.  On May 1, 1999, we issued 316,498 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 23,500 shares with an exercise price of $3.16 per share, as
     compensation for services rendered in connection with arranging our $20.0
     million credit facility.

          5.  We have, from time to time, granted stock options to employees.

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.

                              ROCKFORD CORPORATION



                  1. The name of the corporation is ROCKFORD CORPORATION.

                  2. The amendment adopted by action of the directors and
         stockholders is to amend the corporation's articles of incorporation as
         follows:

                  Amend Article IV so that it reads in its entirety as follows:

                  The corporation shall have authority to issue 20,000,000
                  shares of common stock of the par value of $.01 per share.

                  Amend Article V by replacing the final sentence at the
                  conclusion of existing Article V with the following new
                  sentences:

                  The number of persons to serve on the board of directors, the
                  means of electing them, and their terms of office will be
                  fixed in, or in the manner established by, the bylaws;
                  however, only the board of directors by a two-thirds vote of
                  all directors may increase the number of directors. Only the
                  Board of Directors may fill a vacancy on the Board of
                  Directors, unless the vacancy is for an office elected by a
                  voting group of shareholders and, in that case, only that
                  voting group may fill the vacancy. The shareholders may remove
                  a director from the Board of Directors only for cause.

                  Amend Article VI by adding the following new sentence
                  immediately before the existing text of Article VI:

                  The corporation is required to indemnify each of its directors
                  and officers to the fullest extent permissible under the
                  provisions of Arizona Revised Statutes Title 10, Chapter 8,
                  Article 5 or any successor or amended statute.

                  Add a new Article IX to read as follows:

                                   ARTICLE IX

                  A director of this corporation is not personally liable to the
corporation or its shareholders for monetary damages for breach of fiduciary
duty as a director. This article does not eliminate or limit the liability of a
director for any conduct described in clauses (a) through (d) of Arizona Revised
Statutes Section 10-202.B. 1. If the Arizona Corporation Law is amended to
<PAGE>   2
authorize further elimination or limitation of the liability of a director, then
the liability of a director of the corporation will automatically be eliminated
or limited to the fullest extent permitted by the Arizona Corporation Law as so
amended. Any repeal or modification of this article may not increase the
liability of a director of the corporation arising out of acts or omissions
occurring before the repeal or modification becomes effective.

                  Add a new Article X to read as follows:

                                    ARTICLE X

         Approval of an amendment to these articles of incorporation requires an
affirmative vote of two-thirds of the shareholders present and voting at a
meeting of the shareholders at which a quorum is present. Approval of an
amendment to the bylaws of the corporation requires an affirmative vote of (a)
the board of directors or (b) two-thirds of the shareholders present and voting
at a meeting of the shareholders at which a quorum is present.


                  3. The date of adoption of the amendment by the shareholders
was May 17, 1999.

                  4. The number of shares of the corporation outstanding and the
number of shares entitled to vote thereon were 1,093,218.


                  5. The number of shares voting in favor of adopting the
amendment was 1,011,451 and the number of shares voting against the adoption was

the powers of the Board, the Board shall have the power to determine the times
during which any Option shall be exercisable, the events upon which any Option
shall terminate, the amounts, if any, payable to beneficiaries of an Optionee
upon the death of such Optionee, the exercisability of any Option on the sale of

only a change in form), and other terms of exercise. No member of the Board
shall be eligible to vote on the grant of Options to him or her. All decisions
and determinations of the Board in administering the Plan shall be final.

            3.2 If changes are made to the Code that make it advisable, in the
Board's sole discretion, to change the character of Options for income tax
purposes, the Board may change the character of Options and may impose on

requirements. However, the Board may not change the character or terms of an
outstanding Option without the Optionee's consent.

            3.3 The Committee, subject to the provisions of the Plan, shall make
recommendations to the Board regarding:

                  (a) The employees or directors who shall receive Options, the

provisions of Stock Option Agreements (which need not be identical);

administration of the Plan.

4.    Tax Characteristics of Options.

            Options granted pursuant to the Plan may be designated, but need not
be designated, as Incentive Options. The Stock Option Agreement shall provide
whether an Option is an Incentive Option or a Non-Qualified Option. In the case
of Incentive Options, the aggregate fair market value of the Stock (at the time
the Option is granted) for Options that are


                                       -2-
<PAGE>   4
exercisable for the first time by an Optionee during any calendar year (under
all stock option plans of the Corporation) shall not exceed $100,000.
Non-employee directors of the Corporation shall not be eligible for the grant of
Incentive Options.

            5. Stock Subject to the Plan.

            5.1 Subject to adjustments under Section 11, the aggregate number of
shares of Stock that may be issued on the exercise of Options shall not exceed
250,000. Such Stock may be authorized but unissued shares or treasury shares, as
the Board determines.

            5.2 If an Option expires or is terminated, the shares of Stock
allocated for issuance under such Option may be allocated to a new Option under
the Plan.

            6. Eligibility.

            All individuals who are officers, directors, advisory directors or
employees of the Corporation or a Subsidiary, including employees who are
officers or directors, shall be eligible for selection by the Board to receive
Options under the Plan. Only officers and employees may receive Incentive
Options under the Plan.

            7. Exercise Price and Payment of Withholding Taxes.

            The price at which shares of Stock may be purchased on the exercise
of any Option shall be determined by the Board at the time an Option is granted.
The price shall not be less than 100% of the fair market value of the Stock at
the Grant Date, but if the Corporation desires to grant an Incentive Option to a
Ten Percent Shareholder, the price at which shares may be purchased under such
Option shall not be less than 110% of the fair market value of the Stock at the
Grant Date. Also, if an employee desires to exercise a Non-Qualified Option, the
employee shall pay to the Corporation the federal and state income and
withholding taxes the Corporation determines are payable on the spread between
the fair market value of the Stock at the date of exercise and the Option price.

            8. Term of Options.

            The term of each Option shall be determined by the Board at the
Grant Date. In no case, however, shall the term of any Option exceed ten years
from the Grant Date, or five years in the case of a grant of an Incentive Option
to a Ten Percent Shareholder.

            9. Payment on Exercise of Options.

            The price of an exercised Option and any taxes required to be paid
by the Optionee on exercise of such Option shall be paid:

                  (a)   In cash; or

                  (b) At the discretion of the Board, through the delivery of
Stock with a fair market value equal to the exercise price and withholding
taxes, if any;



                                       -3-
<PAGE>   5
                  or

                  (c) At the discretion of the Board, through a combination of
(a) and (b).

            10. Non-Transferability of Options.

            Options shall not be transferable by the Optionee, but if an
Optionee dies, his or her personal representative may exercise an Option within
90 days of the date of the Optionee's death.

            11. Adjustments.

            If the Corporation:

                  (a) declares a dividend or makes a distribution on its Stock
payable in Stock or securities convertible into Stock; or

                  (b) recapitalizes through a split-up of the outstanding shares
of Stock into a greater number or a combination of the outstanding Stock into a
lesser number; or

                  (c) issues, by reclassification of its Stock, any shares of
Stock, the Board shall make appropriate and equitable adjustments in the number
and kind of shares subject to outstanding Options under the Plan. Any other
adjustments to the Options shall be within the sole discretion of the Board. If
the adjustment would produce fractional shares with respect to any unexercised
Option, the Board may adjust appropriately the number of shares covered by the
Option to eliminate the fractional shares. The price of any shares subject to an
outstanding Option shall be adjusted so there will be no change in the aggregate
purchase price payable upon the exercise of the Option.

            12. Additional Restrictions.

            Notwithstanding any other provisions of the Plan, any Stock Option
Agreement may contain such additional or more restrictive provisions as the
Board deems advisable and consistent with the Plan.

            13. Registration.

            The Plan, the Stock to be issued pursuant to the exercise of
Options, or the Options granted under the Plan, may be registered under the Act.

            14. Effective Date of Plan.

            The Plan shall become effective as of December 15, 1994 and shall
remain in effect for ten years from its effective date, unless it is terminated
earlier by the Board. No Incentive Options may be issued under the Plan unless
the Plan is approved by the stockholders of the Corporation within one year from
the date the Plan is adopted by the Corporation.

            15. Amendments and Termination.

            The Board, in its discretion and at any time, may modify, amend or
terminate the Plan. Neither the termination of the Plan, nor any modification or
amendment thereof, shall adversely affect any rights under an Option previously
granted under the Plan without the consent of the Optionee. Notwithstanding the
foregoing, the Board may amend the Plan to the extent necessary to cause Options
granted under the Plan to meet the requirements of the Act and the Code and
regulations thereunder.

            16. Miscellaneous.

                  (a) Nothing in the Plan or any Option granted shall confer
upon any employee any right to continue in the service of the Corporation or a
Subsidiary.

                  (b) The grant of Options under the Plan, the issuance and
delivery of shares upon the exercise of Options, and any other matters relating
thereto shall be subject to all laws, rules and regulations as may from time to
time be applicable, including but not limited to, any and all rules and
regulations of any stock exchange or exchanges upon which the shares of the
Corporation may be listed and all applicable federal and state securities laws.

                  (c) No person shall acquire any rights as an Optionee under
this Plan unless and until a Stock Option Agreement in the form and containing
the terms specified by the Board shall have been duly executed on behalf of the
Corporation by such officer or officers as the Board shall designate for such
purpose, delivered to the Optionee named therein, and executed by such person.

                  (d) No person shall have any rights as a shareholder with
respect to any shares covered by an Option granted pursuant to the Plan until
the date of the issuance of a share certificate to the Optionee for such shares.

            17. Execution.

Plan and has executed the Plan on the date indicated below.

the Optionee on exercise of such Option shall be paid:

                           (a) In cash; or

                           (b) At the discretion of the Board or the Committee,
through the delivery of Stock with a fair market value equal to the exercise
price and withholding taxes, if any; or

                           (c) At the discretion of the Board or the Committee,
through a combination of (a) and (b).

         10. Non-Transferability of Options.

         Options shall not be transferable by the Optionee, and during his or
her lifetime shall be exercisable only by him or her, but if an Optionee dies,
his or her personal representative may exercise an Option within 90 days of the
date of the Optionee's death.

         11. Adjustments.

         If the Corporation:

                           (a) declares a dividend or makes a distribution on
its Stock payable in Stock or securities convertible into Stock; or

                           (b) recapitalizes through a split-up of the
outstanding shares of Stock into a greater number or a combination of the
outstanding Stock into a lesser number; or

                           (c) issues, by reclassification of its Stock, any
shares of Stock, the Board or the Committee shall make appropriate and equitable
adjustments in the number and kind of shares subject to outstanding Options
under the Plan. Any other adjustments to the Options shall be within the sole
discretion of the Board or the Committee. If the adjustment would produce
fractional shares with respect to any unexercised Option, the Board or the
Committee may adjust appropriately the number of shares covered by the Option to
eliminate the fractional shares. The price of any shares subject to an
outstanding Option shall be adjusted so there will be no change in the aggregate
purchase price payable upon the exercise of the Option.

         12. Additional Restrictions.

         Notwithstanding any other provisions of the Plan, any Stock Option
Agreement may contain such additional or more restrictive provisions as the
Board or the Committee deems advisable and consistent with the Plan.

         13. Registration.

         The Plan, the Stock to be issued pursuant to the exercise of Options,
or the Options granted under the Plan, may be registered under the Act.

         14. Effective Date of Plan.

         The Plan shall become effective as of October 28, 1997, and shall
remain in effect for ten years from its effective date, unless it is terminated
earlier by the Board. No Incentive Options may be issued under the Plan unless
the Plan is approved by the stockholders of the Corporation within one year from
the date the Plan is adopted by the Corporation.

         15. Amendments and Termination.

         The Board, in its discretion and at any time, may modify, amend or
terminate the Plan. Neither the termination of the Plan, nor any modification or
amendment thereof, shall adversely affect any rights under an Option previously
granted under the Plan without the consent of the Optionee. Notwithstanding the
foregoing, the Board may amend the Plan to the extent necessary to cause Options
granted under the Plan to meet the requirements of the Act and the Code and
regulations thereunder.

         16. Miscellaneous.

                           (a) Nothing in the Plan or any Option granted shall
confer upon any employee any right to continue in the service of the Corporation
or a Subsidiary.

                           (b) The grant of Options under the Plan, the issuance
and delivery of shares upon the exercise of Options, and any other matters
relating thereto shall be subject to all laws, rules and regulations as may from
time to time be applicable, including but not limited to, any and all rules and
regulations of any stock exchange or exchanges upon which the shares of the
Corporation may be listed and all applicable federal and state securities laws.

                           (c) No person shall acquire any rights as an Optionee
under this Plan unless and until a Stock Option Agreement in the form and
containing the terms specified by the Board or the Committee shall have been
duly executed on behalf of the Corporation by such officer or officers as the
Board or the Committee shall designate for such purpose, delivered to the
Optionee named therein, and executed by such person.

                           (e) No person shall have any rights as a shareholder
with respect to any shares covered by an Option granted pursuant to the Plan
until the date of the issuance of a share certificate to the Optionee for such
shares.

                              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"). 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 PURCHASE 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 two years'
duration and shall consist of four consecutive six-month Purchase Periods
(individually, a "Purchase Period"). The first Offering Period shall begin on
July 1, 1999. Unless determined otherwise by the Committee or the Board,
Offering Periods shall be overlapping and shall begin on the first day of the
month every 6 months after the first day of the prior Offering Period. During a
Purchase Period, payroll deductions of the participants are accumulated under
this Plan. The first day of each Offering Period is referred to as the "Offering
Date." The last day of each Purchase Period is referred to as the "Purchase
Date." 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 or
Purchase Periods


                                      -4-
<PAGE>   5
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.

                  (c)      If the fair market value on any Purchase Date is less
than the fair market value at the start of the two-year Offering Period, such
Offering Period will automatically end with that Purchase Date.

         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


                                      -5-
<PAGE>   6
employee's payroll deduction account during the Purchase 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.

         9.       PURCHASE PRICE.

                  The purchase price per share (the "Purchase Price") at which a
share of Common Stock will be sold in any Purchase 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 to which such Purchase Period relates 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


                                      -6-
<PAGE>   7
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 Purchase 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 all Offering Periods. 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 Purchase Period with respect to
each Offering Period and may increase or decrease the rate of payroll deductions
as of the start of any Purchase Period. Notwithstanding the foregoing, a
participant may lower the rate of payroll deductions to zero for the remainder
of a Purchase Period. Such changes may be made by filing a new authorization


                                      -7-
<PAGE>   8
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 of the
Offering Period unless changed as described herein. 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 Purchase
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 Purchase 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 Purchase Period will be held in the participant's
account and used to purchase shares in the next Purchase Period during the
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 earliest of the termination of the Offering
Period, 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 Purchase 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"). The shares must remain in the participant's account at the
Plan Financial Agent until the expiration of one year after the purchase of the
shares by the participant; provided that after such period, a participant shall
be free to undertake a disposition (whether by way of sale, gift, or other
transfer) of the shares in his or her account at any time. With respect to full
shares (but not fractional) for which the holding period set forth in the
previous sentence has been satisfied, the participant may move those shares to
another brokerage account of the participant's choosing or request that a stock
certificate for full (but not fractional) shares be issued and delivered to him
or her. 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


                                      -10-
<PAGE>   11
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 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. However,
the participant shall not in any event receive a certificate representing shares
with respect to which the one-year holding period set forth in this section has
not been satisfied until such holding period has been satisfied.

         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


                                      -11-
<PAGE>   12
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 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 Purchase
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


                                      -12-
<PAGE>   13
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 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


                                      -13-
<PAGE>   14
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 Purchase Period a report of his or her account setting forth
with respect to such Purchase 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 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


                                      -14-
<PAGE>   15
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, 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


                                      -16-
<PAGE>   17
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 is adopted effective on July 1, 1999, and shall be
submitted to the stockholders for approval thereof no later than one year before
or after such date. In the event the stockholders have not approved this Plan
within such period, this Plan shall thereupon terminate; all then outstanding
Options shall be cancelled and cease to be in effect; all amounts deducted from
the Compensation of participants and not theretofore applied to the purchase of
shares of Common Stock shall be refunded without interest; and all full shares
held by the Plan Financial Agent for the accounts of participants shall be
delivered to the respective participants and all fractional share interests
shall be sold for the accounts of the participants by the Plan Financial Agent
and the proceeds of such sale distributed to the participants entitled thereto.

         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.

                  existing and engage in noncompetitive outside financial

                  desire to terminate or modify this Employment Agreement on the
                  other. Such notice must be given at least six months before
                  the end of the Initial Term or the applicable Renewal Term.

                  referred to as the "Employment Period."

4.       Compensation and Benefits

         4.1      As remuneration for Employee's services hereunder, the Company
                  shall pay to the Employee, during the continuance of his
                  employment, a total annual base salary of $400,000 payable in
                  installments under the Company's standard payroll policies
                  (base salary). The base salary may be increased as the
                  Compensation Committee of the Board of Directors of the
                  Company reasonably determines.

         4.2      In addition to the remuneration provided in Section 4.1 above,
                  the Company shall pay the Employee an annual performance bonus
                  (the "bonus") based on the Company's profit and bonus plan
                  (the "plan") as approved by the Board of Directors or the
                  Compensation Committee. Such annual bonus shall provide
                  incentives up to 50% of base salary each Fiscal Year in the
                  event the plan is achieved. This base salary and bonus shall
                  be referred to as the Employee's "total compensation."

                  4.2.1    Bonus payments provided herein shall be paid to the
                           Employee within 30 days after delivery to the Board
                           of Directors of the audited (or if there is no audit,
                           Board approved) financial statements of the Company
                           for the relevant Fiscal Year.

                  4.2.2    The Employee shall not be entitled to the bonus or
                           any portion thereof unless he has been employed
                           throughout the entire relevant Fiscal Year; provided,
                           however, that if the Employee's employment is
                           terminated and sections 5.2 or 5.4 below require
                           payment of partial bonus, then Employee will receive
                           a pro rata bonus ("Pro Rata Bonus") based on the
                           number of months which elapsed during the relevant
                           Fiscal Year before the termination, notwithstanding
                           that he was not employed on the last day of the
                           Fiscal Year. Unless Sections 5.2 or 5.4 require
                           payment of a Pro Rata Bonus, the Employee shall not
                           be entitled to the bonus or any portion thereof for
                           the Fiscal Year in which his employment is
                           terminated.

                  4.2.3    For the purposes of this Agreement, the term "Fiscal
                           Year" shall mean the Company's Fiscal Year for
                           accounting purposes ending December 31.

         4.3      The Employee shall be entitled to receive such employee
                  benefits, including but not limited to, accident, health,
                  disability and travel insurance, in accordance with the
                  guidelines applicable to the Company's other senior executive
                  officers and all employees generally; provided that the
                  Company shall pay for the cost of coverage under all such
                  Plans to the same extent as it pays the cost for other senior
                  executive officers. The Company will reimburse the Employee
                  for amounts paid by the Employee for any supplemental
                  disability insurance premiums necessary to provide disability
                  income equal to the Employee's base salary. The Employee is
                  entitled to five (5) weeks of paid vacation per calendar year,
                  with such vacation to be scheduled and taken in accordance
                  with the Company's standard vacation policies. The Employee
                  shall be entitled to receive an annual physical from a
                  physician of his choice with the cost of such physical borne
                  by the Company (to the extent it is not paid for by the health
                  insurance provided by Company).

<PAGE>   3
         4.4      The Company shall enter into an agreement with the Employee
                  establishing a "split dollar" life insurance program in a face
                  amount agreed by Employee and Company. The Company shall pay
                  100% of the annual premiums on the underlying life insurance
                  contract up to a maximum payment of $36,000 per year and upon
                  the Employee's death, the Company shall be entitled to receive
                  a payment equal to the premiums paid. Such agreement shall be
                  subject to such other terms and conditions to which the
                  Company and Employee agree.

         4.5      The Company will reimburse the Employee for any and all
                  necessary, customary, and usual expenses, properly receipted
                  in accordance with Company policies, incurred by the Employee
                  on behalf of the Company. Additionally, the Company shall pay
                  membership dues for the Employee to join various civic and
                  professional organizations mutually agreed to by the Employee
                  and the Company.

         4.6      If the Employee is unable to perform his duties hereunder
                  because of his physical or mental illness, the Company will
                  continue to pay the Employee his then annual base salary for
                  up to 100 business days of such period of physical or mental
                  illness during any Fiscal Year. The Company shall have the
                  right to require a medical certificate for absences of more
                  than 20 business days and have the Employee examined by a
                  physician of its choice for any absence exceeding 45 days. Any
                  payments hereunder shall be reduced by any payments made to or
                  with respect to the Employee as salary continuation under the
                  provisions of any disability or workers compensation program
                  or arrangement to which the Company contributes or reimburses
                  the Employee for premiums.

         4.7      Employee shall be entitled to participate in the Company's
                  Stock Option Plan as determined by the Board. The Board and
                  Compensation Committee intend to grant Employee an initial
                  option under this Agreement to purchase up to 20,000 shares
                  under the Plan.

5.       Termination

         5.1      The Company may terminate the Employee's employment at any
                  time after the first anniversary date of this Agreement by
                  giving written notice to the Employee not less than six months
                  prior to the effective date of such termination; provided,
                  that the Company may terminate the Employee's employment
                  immediately upon written notice to Employee of termination for
                  Good Cause (as defined below). Employee may terminate his
                  employment with the Company immediately upon written notice to
                  the Company of termination for Good Reason (as defined below).
                  After delivery of a termination notice described in this
                  Section 5.1, the Company shall have the right to exclude the
                  Employee from the Company's premises or from performing any
                  services for the Company; provided that the Company shall
                  continue to compensate the Employee as otherwise required by
                  the terms of this Agreement.

                  5.1.1    For the purposes of this Agreement, "Good Reason" for
                           termination by Employee shall be deemed to occur in
                           the event (i) the Company changes the Employee's
                           position as Chief Executive Officer or materially
                           changes the Employee's functions, duties, or
                           reporting responsibilities which would cause
                           Employee's position with the Company to become of
                           materially lesser responsibility or importance than
                           those associated with his functions, duties, or
                           responsibilities as of the date hereof, (ii) the
                           Employee is required without the Employee's consent
                           to relocate to an employment location that is outside
                           metropolitan Phoenix, Arizona, (iii) the Employee's
                           annualized base salary rate or target bonus amount
                           during the Employment Period is reduced from the
                           rates set forth in Sections 4.1 and 4.2, as such
                           rates may be adjusted by the Compensation Committee,
                           unless


                                      -3-
<PAGE>   4
                           the Employee agrees to a reduction; or (iv) there
                           exists a "Charge in Control" (as defined on Exhibit A
                           attached hereto and incorporated herein) of the
                           Company prior to an initial public offering of
                           Company's common stock in one or more series of
                           related transactions.

                  5.1.2    For purposes of this Agreement, "Good Cause" for
                           termination by the Company means: (i) the Employee's
                           indictment, conviction or plea of guilty to any act
                           or acts constituting a felony under the laws of the
                           United States, any state thereof or any foreign
                           jurisdiction, (ii) failing or refusing, after a
                           30-day written notice from the Company and an
                           opportunity during such 30-day period for the
                           Employee to cure, to comply in a material respect
                           with the Company's policies, written or otherwise, or
                           with the material duties or obligations imposed upon
                           him under this Agreement, (iii) any act by the
                           Employee that is unlawful or brings the Company into
                           disrepute unless the Employee believed in good faith
                           that the act was lawful and not opposed to the
                           Company's best interests, or (iv) any act by the
                           Employee involving theft or dishonesty involving
                           $1,000 or more of the Company's property. Good cause
                           shall be determined by a vote of the Board of
                           Directors.

         5.2      If the Company terminates the employment of the Employee
                  during the Employment Period for other than Good Cause or if
                  Employee terminates his employment with the Company during the
                  Employment Period for Good Reason then the Company shall pay
                  to Employee any portion of his annual base salary which has
                  been accrued but not been paid as of the termination date
                  ("Accrued Salary") and his Pro Rata Bonus. In addition, the
                  Company shall pay the Employee an amount equal to the
                  Employee's base salary for the 18-month period immediately
                  preceding the Employee's termination of employment. Such
                  amount shall be paid according to the Company's payroll
                  practices over the 18-month period immediately following the
                  Employee's termination of employment. Further, the Company
                  will maintain all benefits as described in Section 4.3,
                  including without limitation all medical and disability
                  benefits, for the 18-month period immediately following the
                  Employee's termination of employment. Alternatively, at
                  Employee's election, Company shall reimburse the cost of the
                  Employee's COBRA premium during the applicable "period of
                  coverage" as defined in Section 4980B(f)(2)(B) of the Internal
                  Revenue Code should the Employee elect to receive such COBRA
                  coverage.

         5.3      If the Employee's employment is terminated for any reason
                  other than those set forth in Sections 5.2 or 5.4, the Company
                  shall not be obligated to pay any severance, pay any bonus, or
                  provide any benefits to the Employee; provided, that the
                  Company shall pay to Employee his Accrued Salary.

         5.4      The employment of the Employee shall terminate upon the
                  Employee's death. In the event of the Employee's death, the
                  Company shall be obliged within 30 days thereafter to pay to
                  Employee's estate all Accrued Salary and, if applicable, Pro
                  Rata Bonus. The Company shall have the right to terminate the
                  Employee's employment upon 100 business days prior written
                  notice in the event of the Employee's total disability. In the
                  event of the Employee's termination as the result of his total
                  disability, the Company shall, for a period of 12 months
                  following termination pay to the Employee in each such month
                  1/12 of his total compensation for the 12 month period prior
                  to termination; provided, however, that the dollar amount of
                  any payment hereunder shall be reduced by any payments made to
                  or with respect to the Employee as salary continuation under
                  the provisions of any disability or workers compensation
                  program or arrangement to which the Company contributes or
                  reimburses the Employee for premiums. For purposes hereof, a
                  total disability is a physical or mental disability which
                  results in the Employee's inability to substantially perform
                  his duties for a period of six consecutive months or for a
                  period of 180 days within any period of 12 consecutive months.

         5.5      Upon termination of his employment with the Company, the
                  Employee shall promptly return to the Company of his own
                  accord all documents, memoranda, computer discs, data,
                  electronically-stored files, notes and drafts in whatever
                  medium relating to the Company's business, together with any
                  and all carbon or other copies thereof. The Employee shall not
                  be entitled to withhold from the Company any of the
                  aforementioned papers or documents.

         5.6      The Employee's receipt of any of the benefits to be provided
                  under this Agreement following termination of the Employee's
                  employment with the Company shall be subject to the Employee's
                  compliance with any reasonable and lawful policies or
                  procedures of the Company relating to employee severance,
                  including the execution and delivery by the Employee of a
                  release reasonably satisfactory to the Company of any and all
                  claims that the Employee may have against the Company or any
                  related person, except for the continuing obligations provided
                  herein.

6.       Covenants

         6.1      Nondisclosure. The Employee shall not make use of, divulge, or
                  otherwise disclose, directly or indirectly, whether during the
                  term of this Agreement or at any time thereafter, any trade
                  secret or other confidential or proprietary information
                  concerning the business (including, but not limited to, its
                  products, employees, customers, suppliers, services,
                  practices, or policies) of the Company of which the Employee
                  may learn or be aware as a result of the Employee's employment
                  during the term of the Agreement, except to the extent such
                  use or disclosure is (i) required by applicable law; (ii)
                  lawfully obtainable from other sources not under a duty of
                  confidentiality with the Company, (iii) authorized in writing
                  by the Company, or (iv) necessary to the performance of this
                  Agreement and in furtherance of the Company's best interest.
                  The provisions of this provision shall survive the expiration,
                  suspension, or termination, for any reason, of this Agreement.

         6.2      Trade Secrets. The Employee, during the term of employment
                  under this Agreement, will have access to and become
                  acquainted with various trade secrets and proprietary and
                  confidential information, consisting of, but not limited to,
                  processes, computer programs, compilation of information,
                  records, sales procedures, customer requirements, pricing
                  techniques, customer lists, methods of doing business and
                  other confidential information (collectively referred to as
                  "Trade Secrets"), which are owned by the Company and regularly
                  used in the operation of its business, but in connection with
                  which the Company takes precautions to prevent dissemination
                  to persons other than certain directors, officers and
                  employees. The Employee agrees not to disclose any of the
                  Trade Secrets, directly or indirectly, or use them in any way,
                  either during the term of this Agreement or at any time
                  thereafter, except as required in the course of employment by
                  the Company and for its benefit. All records, files,
                  information, data, documents, drawings, specifications,
                  software, electronically-stored data, equipment, and similar
                  items (and all reproductions thereof) relating to the business
                  of the Company, including without limitation, all records
                  relating to suppliers or customers ("Documents"), shall remain
                  the exclusive property of the Company and shall not be removed
                  from the premises of the Company or its affiliates under any
                  circumstances whatsoever, except in the normal course of
                  business or with the prior consent of the Company. Upon
                  termination of employment, the Employee agrees to promptly
                  deliver to the Company all Documents in the possession or
                  under the control of Employee.

         6.3      Non-Competition. Without the prior written consent of the
                  Company:

                  6.3.1    During the Employment Period, the Employee shall not
                           directly or indirectly, either as an individual, a
                           partner, or a joint venturer, or in any other
                           capacity (A) engage in any business that competes
                           with the Company by marketing to customers who are
                           substantially similar to the customers of the Company
                           during


                                      -5-

                           render services to a competitor of the Company as a
                           director, officer, agent, employee, or consultant,
                           (C) contact, solicit, or attempt to solicit or accept
                           or direct business that is competitive with business

                  6.3.2    Until the later of (1) 12 months after termination of
                           the Employment Period or (2) 6 months after final
                           payment of severance or disability payments under
                           Sections 5.2 or 5.4 after the Employment Period ends,
                           the Employee shall not, directly or indirectly,
                           either as an individual, a partner, or a joint
                           venturer, or in any other capacity, (A) engage in any
                           business that competes with the Company by marketing
                           to customers who are substantially similar to the
                           customers of the Company during the Employment
                           Period, (B) accept employment with or render services
                           to a competitor of the Company as a director,

                           contact, solicit, or attempt to solicit or accept or
                           direct business that is competitive with business

                           from any of the Company's customers.

         6.4      Non-Solicitation. During the term of this Agreement and until
                  the later of (1) 12 months after termination of the Employment
                  Period or (2) 6 months after final payment of severance or
                  disability payments under Sections 5.2 or 5.4 after the
                  Employment Period ends, the Employee will not, on behalf of
                  the Employee or on behalf of any other individual,
                  association, or entity, call on any of the customers of the
                  Company for the purpose of soliciting or inducing any of such
                  customers to acquire, or providing to any of such customers,
                  any product or service provided by the Company nor will the
                  Employee in any way, directly or indirectly, as agent or
                  otherwise, in any other manner solicit, influence, or
                  encourage such customers to take away or to divert or direct
                  their business to the Employee or any other individual,
                  association, or entity.

         6.5      No Raiding of Employees. During the term of this Agreement and
                  until the later of (1) 12 months after termination of the
                  Employment Period or (2) 6 months after final payment of
                  severance or disability payments under Sections 5.2 or 5.4
                  after the Employment Period ends, the Employee will not (A)
                  induce any employee of the Company to leave the Company or to
                  accept any other employment or position or (B) assist any

                  employee.

         6.6      Special Remedies and Enforcement. The Employee recognizes and
                  agrees that a breach by the Employee of any of the covenants
                  set forth in this Section 6 would cause irreparable harm to
                  the Company, that the Company's remedies at law in the event
                  of such breach would be inadequate, and that, accordingly, in
                  the event of such breach, a restraining order or injunction or
                  both may be issued against the Employee, in addition to any
                  other rights and remedies which are available to the Company.
                  The Company and the Employee agree that, if the Company
                  breaches its obligation to pay the Employee severance under
                  Section 5.2, the Employee shall not be bound by the terms of
                  any provision of this Section 6.

7.       STOCK PURCHASING RIGHTS.

         7.1      To the extent the Company makes any future equity offerings
                  prior to its initial public offering the Company will use best
                  efforts to offer Employee the right to participate on terms
                  and conditions similar to those offered to any other existing
                  stockholder.

8.       REGISTRATION RIGHTS OF EMPLOYEE.

         8.1      LOCK-UP PROVISIONS. Employee acknowledges and understands that
                  if the Company is able to complete an initial public offering,
                  all common stock owned by Employee may not be registered by
                  the Company in connection with the initial public offering.
                  Employee further acknowledges and agrees that the managing
                  underwriter of the initial public offering of the Company's
                  common stock or a subsequent offering of the Company's common
                  stock may require all shareholders, including the Employee, to
                  agree not to sell any common stock of their common stock for

                               INDEMNITY AGREEMENT

This Agreement is made as of January 1, 1999, by and among ROCKFORD CORPORATION,
an Arizona corporation, ("Corporation") and W. Gary Suttle ("Agent")

                                    RECITALS

         1.       The Agent has or is currently serving as a Director and
Officer the Corporation and the Corporation wishes the Agent to continue in such
capacity;

         2.       The Agent is willing, under certain circumstances, to continue
in such capacity provided he is indemnified from and against loss, claim or
expense, including attorneys' fees, incurred by virtue of the fact that Agent
was a Director or Officer of the Corporation;

         3.       The Agent has indicated that he does not regard in the
indemnities available under the Corporation's Charters or Bylaws and any
insurance remaining in effect as adequate to protect him against the risks
associated with his service to the Corporation;

         NOW THEREFORE, in order to induce the Agent to continue to serve as
Director and Officer for the Corporation and in consideration of his continued
service, the Corporation hereby agrees to indemnify the Agent as follows:

                  a.       Subject to the terms of this Agreement, the
Corporation will pay upon request and on behalf of the Agent or his spouse,
executors, administrators or assigns, any amount which he is or becomes legally
obligated to pay because of any claim or claims made against him because of any
act or omission or neglect or breach of duty, including any actual or alleged
error or misstatement or misleading statement, whether or not claimed to be
intentional or made in bad faith, which he commits or suffers while acting in
his capacity as a Director or Officer of the Corporation or solely because of
his being a Director or Officer. This Indemnity Agreement shall cover claims
made which relate to acts or failure to act prior to the date hereof including
claims pursuant to which litigation has either commenced or been threatened. The
payments which the Corporation will be obligated to make hereunder shall include
all attorneys' fees, damages, judgments, settlements and costs, cost of
investigation, and costs of defense of legal actions, claims or proceedings and
appeals therefrom, and costs of attachment or similar bonds.

                  b.       If a claim under this Agreement is not paid by the
Corporation, or on its behalf, within sixty days after written request has been
received by the Corporation, the claimant may at any time thereafter bring suit
against the Corporation to recover the unpaid amount of the claim and if
successful in whole or in part, the claimant shall be entitled to be paid also
all the costs and expenses of prosecuting such claim.

                  c.       In the event of payment under this Agreement, the
Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of the Agent, who shall execute all papers required and shall
do everything that may be necessary to secure such rights,
<PAGE>   2
including the execution of such documents necessary to enable the Corporation
effectively to bring suit to enforce such rights.

                  d.       Although it is the intent of this Indemnity Agreement
to hold Agent harmless from and against any claim, cost or expense, the
Corporation shall not be liable under this Agreement to make any payment in
connection with any claim made against the Agent:

                           (i)      for which payment is actually made to the
Agent under a valid and collectible insurance policy, except in respect of any
excess beyond the amount of payment under such insurance;

                           (ii)     based upon or attributable to the Agent
gaining in fact any personal profit or advantage to which he was not legally
entitled;

                           (iii)    for an accounting of profits made from the
purchase or sale by the Agent of securities of the Corporation within the
meaning of Section 16(b) of the Securities Exchange Act of 1934 and amendments
thereto or similar provisions of any state statutory law or common law;

                           (iv)     for an intentional infliction of harm on the
corporation or its shareholders;

                           (v)      for a violation of Arizona Revised Statutes
section 10-833 relating to unlawful distributions;

                           (vi)     for Agent's gross negligence, willful
misconduct, or intentional violation of law; or

                           (vii)    if indemnity is prohibited by applicable
law.

                  e.       This Indemnity Agreement and the obligations of the
Corporation hereunder shall survive and continue to benefit the Agent with
respect to any claims made after the date Agent is no longer a Director,
Officer, or employee of the Corporation, and after termination of Agents
employment agreement with Corporation, regardless of the reason for discharge or
termination.

                  f.       No costs, charges or expenses for which indemnity
shall be sought hereunder shall be incurred without the Corporation's consent,
which consent shall not be unreasonably withheld.

                  g.       The Agent shall give to the Corporation notice in
writing as soon as practicable of any claim made against him for which indemnity
will or could be sought under this Agreement. Notice to the Corporation shall be
directed to ROCKFORD CORPORATION, 546 South Rockford Drive, Tempe, Arizona
85231, Attention: Corporate Secretary (or such other address as the Corporation
shall designate in writing to the Agent); notice shall be deemed received if
sent by prepaid mail properly addressed, the date of such notice being the date


                                      -2-
<PAGE>   3
postmarked. In addition, the Agent shall give the Corporation such information
and cooperation as it may reasonably require and as shall be within the Agent's
power.

                  h.       When the Corporation receives notice of a claim it is
entitled to participate in the Proceeding at its own expense and to assume the
defense of the Proceeding with counsel reasonably acceptable to Agent. After
notice from Corporation to Agent of its election to assume the defense,
Corporation is not liable for any legal or other expenses subsequently incurred
by Agent in connection with the Proceeding, other than reasonable costs of
investigation or as otherwise provided in this section.

                  i.       Costs and expenses including attorneys' fees incurred
by the Agent in defending or investigating any action, suit, proceeding or
investigation shall be paid by the Corporation in advance of the final
disposition of such matter, if the Agent shall undertake in writing to repay any
such advances in the event that it is ultimately determined that the Agent is
not entitled to indemnification under the terms of this Agreement.

                  j.       Agent may employ his or her own counsel in the
proceeding, but the fees and expenses of counsel, incurred after notice of the
Corporation's assumption of the defense, will be at Agents expense unless (1)
Corporation has authorized Agent's employment of counsel, (2) Agent has
reasonably concluded, based on the opinion of his or her counsel, that there is
a conflict of interest or position between Corporation and Agent in the conduct
of the defense, or (3) Corporation has not in fact employed counsel to assume
the defense. In each of these cases the fees and expenses of counsel for Agent
will be at Corporation's expense if Corporation is determined ultimately to be
responsible to indemnify Agent with respect to the Proceeding.

                  k.       Corporation is not obligated to reimburse the costs
of a settlement unless it has agreed to the settlement. If Agent unreasonably
fails to enter into a settlement agreed to by the opposing party and
Corporation, then Corporation's indemnification obligation to Agent in the
Proceeding will not exceed (1) the amount of the agreed settlement plus (2)
expenses incurred before the settlement could have been effected.

                  1.       This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one instrument. This
Agreement shall survive termination of all agreements between Agent and
Corporation. The termination Agent as an employee of the Corporation shall not
effect the right of Agent to seek indemnity thereafter regardless of the basis
for termination.

                  m.       Nothing herein shall be deemed to diminish or
otherwise restrict the Agents right to indemnification under any provision of
the respective Charters or Bylaws of the Corporation or under applicable law or
available insurance coverage.

                  m.       This Agreement shall be governed by and construed in
accordance with Arizona Law.

                  n.       This Agreement shall be binding upon all successors
and assigns of the Corporation (including any transferee of all or substantially
all of its assets and any successor by


                                      -3-
<PAGE>   4
merger or operation of law) and shall inure to the benefit of the Agent's
spouse, heirs, personal representatives and estate of Agent.

         IN WITNESS WHEREOF, the parties hereto have. caused this Agreement to
be duly executed and signed as of the day and year first above written.

additional cost prior to start of work associated with the change.

4.  DEVELOPMENT SCHEDULE

Hyundai agrees to manufacture the Source Units in accordance with the MOM

Milestone has been met. Rockford shall pay Hyundai the Development Fee. in two
equal installments as more described in the MOM. Payment therefor shall not be
due until ten(10) days after such acceptance and receipt of invoice.

In the event that Hyundai fails to achieve the final Development Milestone in
accordance with the MOM for reasons solely attributable to Hyundai, Hyundai
shall, upon Rockford's request, pay as liquidated damages, at the per diem rate
of a tenth percent(O.1%) out of the Development Fee under Section 3 hereof.
Provided, however, that in no event shall the liquidated damages exceed ten
percent(10%) of the Development Fee. Interest at the rate of two percent(2%) per
month, prorated, shall be charged until payment is actually received on any
amount of the Development Fee that remains unpaid beyond the due date.

6.  ACCEPTANCE

accordance with the foregoing review procedures.

7.  ASSISTANCE FROM ROCKFORD

It is understood by both parties that Rockford will dispatch certain of its
engineers and provide certain components and equipments in order to support and
expedite Hyundai's Source Units Development. Notwithstanding any provision of
components and equipments or assistance by Rockford, it is further understood by

set forth in Sections 8 through 12.

8.  FORECASTS AND ORDERS

8.1 Rockford shall provide Hyundai with forecasts of its requirements for
delivery of the Source Units on a monthly basis in accordance with the MOM. All
such purchase orders shall be deemed (to have been) accepted by Hyundai unless
Hyundai notifies Rockford otherwise by the 10th day of such order month.

8.2 Hyundai understands that Rockford's demand is dependent on market and other
factors beyond Rockford's control. This may result in demand being reduced or
eliminated. Rockford may, however, increase or decrease the volume thus ordered
and accepted not more than three percent (3%), by notifying Hyundai in writing
in not less than thirty(30) days after the date of such purchase order.

8.3 Rockford shall place purchase orders with Hyundai in writing to reach
Hyundai at least thirty (30) days before the shipment date specifying quantity,

I.       LCD
         1.       LCD layout
Hyundai banded over our final layout to Rockford at the meeting.
                  *LCD size is not fixed, which can be decided according to
                  front PCB circuit and Japanese
                  ISO Din size.
         2.       Dot matrix (5x7 type):
                  The view angle will be narrower than normal type LCD.
                  HEI will make it in the consideration of practical use in
                  general car. However, it is impossible to adjust its view
                  angle manually according to your model.
         3.       Flashing
                  -Mute:       When mute function is engaged
                  -Frequency:  While holding under preset scan
                  -Time:       While time adjustment mode is engaged

                  *Time adjustment is implemented by pressing together with
                  "DISP" key and "SEEK" up (hr.) or "SEEK" down (min.) key under
                  time adjustment mode

II.      Conclusion of Design
         1.       CDC:                      B rendering is confirmed
         2.       Card Remocon:             C1 rendering is confirmed
         3.       CDP:                      Basically C
                  *both parties adjusted and agreed design layout, which was
                  handed over to Rockford together with diskette.

<PAGE>   2
                     ROCKFORD CORPORATION DEALER AGREEMENT

         This Agreement is between Rockford Corporation, an Arizona corporation
("Rockford"), and the person or entity names on the signature page of this
Agreement ("Dealer"). This Agreement supersedes any previous Agreement between
Rockford and Dealer. Rockford and Dealer 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 DEALER EXPERIENCE. Dealer has experience in the retail sale of high
         quality consumer electronic products, is in a good and substantial
         financial position, and is skilled at installing mobile audio and
         associated electronics equipment in automobiles.

         1.3 RELIANCE UPON DEALER ABILITY. The Products, as defined below, are
         of a highly technical nature, their proper installation requires great
         skill and experience, and their sale requires dealers who promote the
         sale of Products vigorously and adhere to high sales and service
         standards. Rockford has selected Dealer based on Dealer's
         representations and agreements about its skill, experience, and ability
         as set forth in this Agreement.

         1.4 PURPOSE. The purpose of this Agreement is to state the terms and
         conditions of Rockford's appointment of Dealer as an outlet for retail
         sales of Products and of Dealer's acceptance of such appointment.

2.       DEALERSHIP.

         2.1 APPOINTMENT, PRODUCTS, AND TERRITORY. Rockford appoints Dealer and
         Dealer accepts appointment as a retail dealer for sale of the Rockford
         products (the "Products") from the retail outlets (the "Outlets") and
         with primary responsibility for sales in the territory (the
         "Territory") as each is described in the Addendum to this Agreement.
         Dealer may not advertise or sell the Products outside the Territory, as
         described in the Addendum.

         2.2 LIMITED LICENSE OF NAMES. Rockford grants Dealer a right to use
         during the term of this Agreement Rockford's trademarks and other
         identification (the "Names") described in the Addendum, solely in
         connection with advertising, promotion, and sales of the Products and
         subject to the limitations set forth in this Agreement. Dealer may not
         make other use of the Names, and may not use any other Rockford
         trademarks, products, or other identification, unless Rockford gives
         its prior written consent.

         2.3 CHANGES; APPOINTMENT NOT EXCLUSIVE. Rockford may change the Outlets
         or Territory, or may add or delete Products or Names from Dealer's
         authority, at any time by giving notice of the change to Dealer which
         notice shall be deemed an amendment to the Addendum. Dealer's
         responsibility for the Territory is non-exclusive and Rockford may
         appoint other dealers in the Territory.

3.       TERMS AND CONDITIONS OF SALE. Dealer shall purchase and pay for
         Products at Rockford's bona fide wholesale prices and on the terms and
         conditions specified in the Addendum. Such terms and conditions may be
         modified by Rockford upon notice to Dealer and such modified terms
         shall be effective for orders accepted by Rockford after the date of
         notice.

4.       DUTIES OF ROCKFORD. Rockford shall:

         4.1 supply Dealer with reasonable quantities of Rockford's standard
         sales promotion, advertising, and product related materials without
         cost to Dealer;

         4.2 provide sales assistance and support as deemed necessary by
         Rockford in the form of technical information or advisory personnel,
         including information necessary to keep Dealer's sales personnel
         informed about the Products; and

         4.3 fill orders submitted by Dealer and accepted by Rockford. Rockford

5.       DUTIES OF DEALER. Dealer shall:

         5.1 actively and diligently promote the retail sale of Products from
         the Outlets, and solicit sales from and provide support to existing and
         potential Rockford retail customers within the Territory, on a regular
         basis consistent with good business practice and the high standards
         established by Rockford;

         5.2 refrain from mail order, sales, telephone sales, and sales made
         using the internet or other electronic media. Dealer shall sell
         Products only to retail customers who visit an Outlet in connection
         with each sale of the Products for resale without Rockford's prior
         written consent;

         5.3 in order to maintain and enhance the reputation of the Products for
         high quality and service, thereby enhancing the prospects of Rockford
         and Dealer for sales of the Products, focus its advertising of the
         Products on the high quality of the Products;

         5.4 achieve or exceed standards of performance, including minimum
         purchase requirements for Products, established from time to time by
         Rockford in its sole discretion. Dealer's initial minimum purchase
         requirement shall be as listed in the Addendum and shall thereafter be
         adjusted by Rockford on a regular basis by giving notice to Dealer,
         which notice shall be deemed an amendment to the Addendum;

         5.5 establish and maintain a staff of sales personnel familiar with
         information about the Products provided by Rockford (including their
         operating manuals) and capable of providing consumers with a full
         explanation of the features and characteristics of the Products;

         5.6 display Products so that each line of goods sold may be properly
         demonstrated in a vehicle or in a store display. Rockford may delete
         any Products that Dealer cannot properly demonstrate to a consumer;

         5.7 maintain adequate facilities and personnel to meet Rockfords'
         standards of performance, employ competent installation personnel, and
         have appropriate installation equipment at each Outlet;

         5.8 assist in any reasonable way any purchaser or prospective purchaser
         of Products who may have either an inquiry or complaint;

         5.9 follow Rockford's written instructions for proper installation of
         Products;

         5.10 not modify, repackage, adulterate, mishandle, alter, add labels
         to, or remove labels from any of the Products;

         5.11 conduct its own business under its individual, partnership or
         corporate name. Dealer shall not use any Names as part of Dealer's
         name; and

         5.12 not engage in any practices or make any representations to any
         customer or other person which are false, misleading, incomplete,
         fraudulent, untrue or contrary to Rockford's sales policies or this
         Agreement. Dealer shall make no representations to customers or others
         with respect to Products except those approved in the current warranty
         program or approved in writing by Rockford.

6.       TERM AND TERMINATION. This Agreement is for an initial term of one year
         from the date of acceptance by Rockford, and thereafter shall renew
         each year for an additional one year term; provided, however, that this
         Agreement may be terminated at any time by either party upon 30 days
         notice of termination to the other. No termination shall (1) create any
         liability for direct or consequential damages or (2) release Dealer
         from any of its obligations accrued prior to termination.

7.       SECURITY INTEREST. Dealer grants to Rockford a security interest in all
         Products purchased from Rockford (and the proceeds of such Products),
         to secure payment and performance of all obligations of Dealer to
         Rockford. Dealer shall cooperate with Rockford to perfect this security
         interest and shall execute any financing statements (including
         amendments and continuation statements) and other documents reasonably
         requested by Rockford. Dealer authorizes Rockford to execute on
         Dealer's behalf and file any financing statements (including amendments
         and continuation statements) and other documents as deemed necessary by
         Rockford to evidence and perfect this security interest.

8.       DEFAULT REMEDIES. Upon any default by Dealer, Rockford shall have the
         right:


                                      -2-
<PAGE>   4
         8.1 to terminate this Agreement immediately upon notice to Dealer. Such
         termination shall not limit or exclude any and all other rights of
         Rockford (including rights to recover damages, to offset damages
         against any other amounts due, and to equitable relief) and shall not
         act as an election of its remedies;

         8.2 to declare, in its sole discretion, the entire amount then due
         Rockford (including reasonable collection and attorneys fees and costs)
         to be immediately due and payable;

         8.3 to cancel orders placed by Dealer, or refuse or delay their
         shipment, until the default is corrected in a manner satisfactory to
         Rockford in its sole discretion;

         8.4 to terminate Dealer's right to participate in Rockford special
         program funds (such as Cooperative Advertising and Growth/Volume
         Incentive Rebate programs) and cancel any outstanding amounts credited
         to dealer in connection with such programs;

         8.5 to establish additional requirements that Dealer must satisfy,
         including credit or financial requirements, in order to continue as a
         Rockford dealer;

         8.6 to secure both temporary and permanent injunctive relief against
         any actual or threatened default;

         8.7 to recover direct, indirect, incidental, and consequential damages
         resulting to Rockford as a result of the breach (which shall include
         its costs in connection with the default, including reasonable
         attorneys fees and costs); and

         8.8 to exercise all rights and remedies as secured party under the
         Uniform Commercial Code to enforce the security interest granted in
         this Agreement.

         The remedies set forth above shall be cumulative and shall not be
         exclusive and Rockford's pursuit of one remedy shall not preclude its
         simultaneous or subsequent pursuit of other remedies.

9.       ROCKFORD'S OPTION TO REPURCHASE UPON TERMINATION. Upon termination of
         this Agreement, Rockford may, at its option, repurchase all Products
         still owned by Dealer at the original dealer cost, less freight and
         reconditioning changes are required.

10.      FINANCIAL CONDITION. Dealer shall provide to Rockford upon request
         appropriate financial record to confirm Dealer's ability to fulfill its
         obligations under this Agreement to Rockford and to Dealer's customers.
         If, in Rockford's sole discretion, Dealer's ability to meet its
         obligations is uncertain or Rockford is insecure, Rockford may suspend
         or terminate this Agreement at any time without any liability. Dealer
         agrees that Rockford may conduct confidential, periodic credit checks
         at its discretion.

11.      TAXES. Dealer is responsible for and shall pay promptly when due any
         and all taxes, levies and assessments upon any Products in Dealer's
         inventory, whether paid for or not.

12.      MODIFICATION OF PRODUCTS. Rockford shall have the sole right to change
         the design of the Products or terminate the production of Products, as
         its business judgment requires and without liability to Dealer.

13.      GOODWILL AND USE OF NAMES. All goodwill generated by the use of the
         Names or promotion of the Products shall accrue to Rockford's benefit
         and Dealer disclaims any ownership rights in the Names and goodwill of
         Rockford. Dealer shall use the Names only in a manner and form approved
         before use in writing by Rockford. Dealer acknowledges Rockford's
         exclusive ownership of the Names and agrees not to use, advertise,
         incorporate, or otherwise appropriate the Names for use in the
         promotion of any other line of goods whether manufactured by Rockford
         or not. Each use of the Names or any variation thereof must be
         accompanied by a trademark designation "(R)" or "(TM)" (as instructed
         by Rockford) and must include as a footnote to the ad copy in a size of
         type no smaller than the type of the main body of the ad the words "A
         Trademark of Rockford Corporation, Tempe, Arizona, U.S.A."

14.      BUSINESS RELATIONSHIP. This Agreement does not create a relationship of

         partnership, or employment. Neither party shall have any authority to
         bind or obligate the other or shall be liable for any obligations
         incurred by the other except as expressly provided herein. Dealer is an

         exercising sole and absolute discretion, judgment and control over the
         management and day-to-day operations of its business, and achieving the
         objectives of its business. Dealer shall not act or represent itself,
         directly or by implication, as an agent of Rockford with any authority
         to bind or obligate Rockford in matters of contract, agreement,
         warranty or otherwise.

15.      INDEMNIFICATION. Dealer shall defend, indemnify and hold harmless
         Rockford, and its employees and agents, from all fines, suits,

         actions of any kind by anyone (including reasonable attorneys' fees and
         costs) arising from or connected with the activities or operations of
         Dealer, its employees, or agents. Rockford shall indemnify Dealer in
         product liability actions brought against Dealer involving solely the
         defective manufacture or design of Products; however, Rockford shall
         not indemnify Dealer against product liability actions arising from any
         practices or representations by Dealer to any customer or to the trade

         Agreement.

         upon notice to Dealer, this Agreement may be amended only by a written
         document signed by both parties. Any waiver of a right, obligation or
         default must be in writing and signed by all parties; no failure to
         exercise any right or power under this Agreement or to insist upon
         strict compliance by the other party hereunder shall constitute a
         waiver for the right to exercise such right or power or insist on
         strict compliance. A waiver of one right, obligation or default shall
         not be construed as a waiver of any other or subsequent right,

24.      SEVERABILITY. If any provision of the Agreement is deemed contrary to,
         prohibited by, or invalid under applicable law, or is inoperative for

restrictions of record, or any applicable building code, regulation or ordinance

days after receipt of Lessor's written statement setting forth the amount of
such increase and the computation thereof. If the term of this Lease shall not
expire concurrently with the expiration of the tax fiscal year, Lessee's
liability for increased taxes for the last partial-lease year shall be prorated
on an annual basis.
     10.2 ADDITIONAL IMPROVEMENTS. Notwithstanding paragraph 10.1 hereof, Lessee
shall pay to Lessor upon demand therefor the entirety of any increase in real
property tax if assessed solely by reason of additional improvements placed upon
the Premises by Lessee or at Lessee's request.
     10.3 DEFINITION OF "REAL PROPERTY TAX". As used herein, the term "real
property tax" 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 on the Premises 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, as against any legal or equitable interest of Lessor in the
Premises or in the real property of which the Premises are a part, as against
Lessor's right to rent or other income therefrom, and as against Lessor's
business of leasing the Premises. The term "real property tax" shall also
include any tax, fee, levy, assessment or charge (1) in substitution of,
partially or totally, any tax, fee, levy, assessment or charge hereinabove

interest in the Premises or which is added to a tax or charge hereinbefore
included within the definition of real property tax by reason of such transfer,
or (v) which is imposed by reason of this transaction, any modifications or
changes hereto, or any transfers hereof.
     10.4 JOINT ASSESSMENT. If the Premises are not separately assessed,
Lessee's liability 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  PERSONAL PROPERTY TAXES.
           (a) Lessee shall pay prior to delinquency all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all other personal
property of Lessee contained in the Premises or elsewhere. When possible, Lessee
shall cause said trade fixtures, furnishings, equipment and all other personal
property to be assessed and billed separately from the real property of Lessor.
           (b) lf any of Lessee's said personal property shall be assessed with
Lessor's real property, Lessee shall pay Lessor the taxes attributable to Lessee
within 10 days after receipt of a written statement setting forth the taxes
applicable to Lessee's property.

11. UTILITIES. Lessee shall pay for all water, gas, heat, light, power,
telephone and other utilities and services supplied to the Premises, together
with any taxes thereon. If any such services are not separately metered to
Lessee, Lessee shall pay a reasonable proportion to be determined by Lessor of
all charges jointly metered with other premises.

12.  ASSIGNMENT AND SUBLETTING.
     12.1 LESSOR'S CONSENT REQUIRED. Lessee shall not voluntarily or - by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Lessee's interest in this Lease or In the Premises
without Lessor's prior written consent, which Lessor shall not unreasonably
withhold. Lessor shall respond to Lessee's request for consent hereunder in a
timely manner and any attempted assignment, transfer, mortgage, encumbrance or
subletting without such consent shall be void, and shall constitute a breach of
this Lease.
     12.2 LESSEE AFFILIATE. Notwithstanding the provisions of paragraph 12.1
hereof, Lessee may assign or sublet the Premises, or any portion thereof,
without Lessor's consent, to any CORPORATION which controls, is controlled by or
is under common control with Lessee, or to any corporation resulting from the
merger or consolidation with Lessee, or to any person or entity which acquires
all the assets of Lessee as a going concern of the business that is being
conducted on the Premises, provided that said assignee assumes, in full, the
obligations of Lessee under this Lease. Any such assignment shall not, in any
way, affect or limit the liability of Lessee under the terms of this Lease even
if after such assignment or subletting the terms of this Lease are materially
changed or altered without the consent of Lessee, the consent of whom shall not
be necessary.
     12.3 NO RELEASE OF LESSEE. Regardless of Lessor's consent, no subletting or
assignment shall release Lessee of Lessee's obligation or alter the primary
liability of Lessee to pay the rent and to perform all other obligations to be
performed by lessee hereunder. The acceptance of rent by Lessor from any other
person shall not be deemed to be a waiver by Lessor of any provision hereof.
Consent to one assignment or subletting shall not be deemed consent to any
subsequent assignment or subletting. In the event of default by any assignee of
Lessee or any successor of Lessee, in the performance of any of the terms
hereof, Lessor may proceed directly against Lessee without the necessity of
exhausting remedies against said assignee. Lessor may consent to subsequent
assignments or subletting of this Lease or amendments or modifications to this
Lease with assignees of Lessee, without notifying Lessee, or any successor of
Lessee, and without obtaining its or their consent thereto and such action shall
not relieve Lessee of liability under this Lease.
     12.4 ATTORNEY'S FEES. In the event Lessee shall assign or sublet the
Premises or request the consent of Lessor to any assignment or subletting or if
Lessee shall request the consent of Lessor for any act Lessee proposes to do
then Lessee shall pay Lessor's reasonable attorneys fees incurred in connection
therewith, such attorneys fees not to exceed $350.00 for each such request.

13.  DEFAULTS; REMEDIES.
     13.1 DEFAULT.. The occurrence of any one or more of the following events
shall constitute a material default and breach of this Lease by Lessee:
           (a) The vacating or abandonment of the Premises by Lessee.
           (b) The failure by Lessee to make any payment of rent or any other
payment required to be made by Lessee hereunder, as and when due, where such
failure shall continue for a period of three days after written notice thereof
from Lessor to Lessee. In the event that Lessor serves Lessee with a Notice to
Pay Rent or Quit pursuant to applicable Unlawful Detainer statutes such Notice
to Pay Rent or Quit shall also constitute the notice required by this
subparagraph.
           (c) The failure by Lessee to observe or perform any of the covenants,
conditions or provisions of this Lease to be observed or performed by Lessee,
other than described in paragraph (b) above, where such failure shall continue
for a period of 3O days after written notice thereof from Lessor to Lessee;
provided, however, that if the nature of Lessee's default is such that more than
30 days are reasonably required for its cure, then Lessee shall not be deemed to
be In default If Lessee commenced such cure within said 30-day period and
thereafter diligently prosecutes such cure to completion.
           (d) (I) The making by Lessee of any general arrangement or assignment
for the benefit of creditors; (ii) Lessee becomes a "debtor" as defined in 11
U.S.C. Section 101 or any successor statute thereto (unless, in the case of a
petition filed against Lessee, the same is dismissed within 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 30 days; or (iv) the
attachment, execution or other judicial seizure of substantially all of
<PAGE>   5
Lessee's assets located at the Premises or of Lessee's interest in this Lease,
where such seizure is not discharged within 30 days. Provided, however, in the
event that any provision of this paragraph 13.1

                      (d) is contrary to any applicable law, such provision
shall be of no force or effect

                      (e) The discovery by Lessor that any financial statement
given to Lessor by Lessee, any assignee of Lessee, any subtenant of Lessee, any
successor in interest of Lessee or any guarantor of Lessee's obligation
hereunder, and any of them, was materially false.

           13.2 REMEDIES. In the event of any such material default or breach by
Lessee, Lessor may at any time thereafter, with or without notice or demand and
without limiting Lessor in the exercise of any right or remedy which Lessor may
have by reason of such default or breach:

                      (a) Terminate Lessee's right to possession of the Premises
by any lawful means, in which case this Lease shall terminate and Lessee shall
immediately surrender possession of the Premises to Lessor. In such event Lessor
shall be entitled to recover from Lessee all damages incurred by Lessor by
reason of Lessee's default including, but not limited to, the cost of recovering
possession of the Premises: expenses of reletting. including necessary
renovation and alteration of the Premises, reasonable attorney's fees, and any
real estate commission actually paid; the worth at the time of award by the
court having jurisdiction thereof of the amount by which the unpaid rent for the
balance of the term after the time of such award exceeds the amount of such
rental loss for the same period that Lessee proves could be reasonably avoided;
that portion of the leasing commission paid by Lessor pursuant to Paragraph 15
applicable to the unexpired term of this Lease.

                      (b) Maintain Lessee's right to possession in which case
this Lease shall continue in effect whether or not Lessee shall have abandoned
the Premises. In such event Lessor shall be entitled to enforce all of Lessor's
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

                      (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. Unpaid installments of rent and other unpaid monetary obligations
of Lessee under the terms of this Lease shall be at interest from the date due
at the maximum rate then allowable by law.

           13.3 DEFAULT BY LESSOR. Lessor shall not be in default unless Lessor
fails to perform obligations required of Lessor within a reasonable time, but in
no event later than thirty (30) days after written notice by Lessee to Lessor
and to the holder of any first mortgage or deed of trust covering the Premises
whose name and address shall have theretofore been furnished to Lessee in
writing, specifying wherein Lessor has failed to perform such obligation;
provided, however, that If the nature of Lessor's obligation is such that more
than thirty (30) days are required for performance then Lessor shall not be in
default if Lessor commences performance within such 30-day period and thereafter
diligently prosecutes the same to completion.

           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 on
Lessor by the terms of any mortgage or trust deed covering the Premises.
Accordingly, if any installment of rent or any 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 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 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 rent, then rent shall automatically become due and
payable quarterly in advance, rather than monthly, notwithstanding paragraph 4
or any other provision of this Lease to the contrary.

           13.5 IMPOUNDS. In the event that a late charge is payable hereunder,
whether or not collected, for three (3) installments of rent or any other
monetary obligation of Lessee under the terms of this Lease, Lessee shall pay to
Lessor, if Lessor shall so request, in addition to any other payments required
under this Lease, a monthly advance installment, payable at the same time as the
monthly rent, as estimated by Lessor, for real property tax and insurance
expenses on the Premises which are payable by Lessee under the terms of this
Lease. Such fund shall be established to insure payment when due, before
delinquency, of any or all such real property taxes and insurance premiums. If
the amounts paid to Lessor by Lessee under the provisions of this paragraph are
insufficient to discharge the obligations of Lessee to pay such real property
taxes and insurance premiums as the same become due, Lessee shall pay to Lessor,
upon Lessor's demand, such additional sums necessary to pay such obligations.
All moneys paid to Lessor under this paragraph may be intermingled with other
moneys of Lessor and shall not bear interest. In the event of a default in the
obligations of Lessee to perform under this Lease, then any balance remaining
from funds paid to Lessor under the provisions of this paragraph may, at the
option of Lessor, be applied to the payment of any monetary default of Lessee in
lieu of being applied to the payment of real property tax and insurance
premiums.

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 "condemnation"), 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 10% of the floor area of the
building on the Premises, or more than 25% of the land area of the Premises
which is not occupied by any building, is taken by condemnation, Lessee may, at
Lessee's option, to be exercised in writing only 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 rent shall be reduced in the
proportion that the floor area of the building taken bears to the total floor
area of the building situated on the Premises. No reduction of rent shall occur
if the only area taken is that which does not have a building located thereon.
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 such power
shall be the property of Lessor, whether such award shall be made as
compensation for diminution in value of the leasehold or for the taking of the
fee, or as severance damages; provided, however, that Lessee shall be entitled
to any award for loss of or damage to Lessee's trade fixtures and removable
personal property. In the event that this Lease is not terminated by reason of
such condemnation, Lessor shall to the extent of severance damages received by
Lessor in connection with such condemnation, repair any damage to the Premises
caused by such condemnation except to the extent that Lessee has been reimbursed
therefor by the condemning authority. Lessee shall pay any amount in excess of
such severance damages required to complete such repair.

15.  BROKER'S FEE.

           (a) Upon execution of this Lease by both parties, Lessor shall pay to
Rand Commercial Brokers Licensed real estate broker(s), a fee as set forth in a
separate agreement between Lessor and said broker(s)
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

           (b) Lessor further agrees that if Lessee exercises any Option as
defined in paragraph 39.1 of this Lease, which is granted to Lessee under this
Lease, or any subsequently granted option which is substantially similar to an
Option granted to Lessee under this Lease, or if Lessee acquires any rights to
the Premises or other premises described in this Lease which are substantially
similar to what Lessee would have acquired had an Option herein granted to
lessee been exercised, or if Lessee remains in possession of the Premises after
the expiration of the term of this Lease after having failed to exercise an
Option, or if said broker(s) 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, 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 execution of this Lease.

        (c) Lessor agrees to pay said fee not only on behalf of
Lessor but also on behalf of any person, corporation, association, or other
entity having an ownership interest in said real property or any part thereof,
when such fee is due hereunder. Any 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 Lessor's obligation under this Paragraph 15. Said broker
shall be a third party beneficiary of the provisions of this Paragraph 15.

16.  ESTOPPEL CERTIFICATE.
           (a) Lessee shall at any time upon not less than ten (10) days' prior
written notice from Lessor execute, acknowledge and deliver to Lessor a
statement in writing (i) certifying that this Lease is unmodified and in full

certifying that this Lease, as so modified, is in full force and effect) and the
date to which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to Lessee's knowledge, any uncured defaults on
the part of Lessor hereunder, or specifying such defaults if any are claimed.
Any such statement may be conclusively relied upon by any prospective purchaser
or encumbrancer of the Premises.
           (b) At Lessor's option, Lessee's failure to deliver such statement
within such time shall be a material breach of this Lease or shall be conclusive
upon Lessee (i) that this Lease is in full force and effect, without
modification except as may be represented by Lessor, (ii) that there are no
<PAGE>   6
uncured defaults in Lessor's performance, and (iii) that not more than one
moth's rent has been paid in advance or such failure may be considered by Lessor
as a default by Lessee under this Lease.
           (c) If Lessor desires to finance, refinance, or sell the Premises, or
any part thereof, Lessee hereby agrees to deliver to any lender or purchaser
designated by Lessor such financial statements of Lessee as may be reasonably
required by such lender or purchaser. Such statements shall Include the past
three years' financial statements of Lessee. All such financial statements shall
be received by Lessor and such lender or purchaser In confidence and shall be
used only for the purposes herein set forth.

17. LESSOR'S LIABILITY. The term "Lessor" as used herein shall mean only the
owner or owners at the time In question of the fee title or a lessee's Interest
in a ground lease of the Premises, and except as expressly provided in Paragraph
15, In the event of any transfer of such title or interest, Lessor herein named
(and in case of any subsequent transfers then the grantor) shall be relieved
from and after the date of such transfer of all liability as respects Lessor's
obligations thereafter to be performed, provided that any funds in the hands of
Lessor or the then grantor at the time of such transfer, in which Lessee has an
Interest, shall be delivered to the grantee. The obligations contained in this
Lease to be performed by Lessor shall, subject as aforesaid, be binding on
Lessor's successors and assigns, only during their respective periods of
ownership.

18. SEVERABILITY. The invalidity of any provision of this Lease as determined by
a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

19. INTEREST ON PAST-DUE OBLIGATIONS. Except as expressly herein provided, any
amount due to Lessor not paid when due shall bear interest at the maximum rate
then allowable by law from the date due. Payment of such interest shall not
excuse or cure any default by Lessee under this Lease, provided, however, that
Interest shall not be payable on late charges incurred by Lessee nor on any
amounts upon which late charges are paid by Lessee.

20. TIME OF ESSENCE. Time Is of the essence.

21. Additional Rent. Any monetary obligations of Lessee to Lessor under the
terms of this Lease shall be deemed to be rent.

22. INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS. This Lease contains all
agreements of the parties with respect to any matter mentioned herein. No prior
agreement or understanding pertaining to any such matter shall be effective.
This Lease may be modified in writing only, signed by the parties In interest at
the time of the modification. Except as otherwise stated In this Lease, Lessee
hereby acknowledges that neither the real estate broker listed In Paragraph 15
hereof nor any cooperating broker on this transaction nor the Lessor or any
employees or agents of any of said persons has made any oral or written
warranties or representations to Lessee relative to the condition or use by
Lessee of said Premises and Lessee acknowledges that Lessee assumes all
responsibility regarding the Occupational Safety Health Act, the legal use and
adaptability of the Premises and the compliance thereof with all applicable laws

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 notice to Lessee.

24. WAIVERS. No waiver by Lessor or any provision hereof shall be deemed a
waiver of any other provision hereof or of any subsequent breach by Lessee of
the same or any other provision. Lessor's consent to, or approval of any act
,shall not be deemed to render unnecessary the obtaining of Lessor's consent to
or approval of any subsequent act by Lessee. The acceptance of rent hereunder by
Lessor shall not be a waiver of any preceding breach by Lessee of any provision
hereof, other than the failure of Lessee to pay the particular rent so accepted,
regardless of Lessor's knowledge of such preceding breach at the time of
acceptance of such rent.

25. RECORDING. Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a "short form" memorandum of this
Lease for recording purposes.

shall be deemed both a covenant and a condition.

and to any and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extensions thereof.

Premises shall not be disturbed If Lessee is not in default and so long as
Lessee shall pay the rent and observe and perform all of the provisions of this

mortgagee, trustee or ground lessor shall elect to have this Lease prior to the
lien of its mortgage, deed of trust or ground lease, and shall give written

attornment, a subordination or to make this Lease prior to the lien of any
mortgage, deed of trust or groundlease, as the case may be. Lessee's failure to
execute such documents within 10 days after written demand shall constitute a
material default by Lessee hereunder, or, at Lessor's option, Lessor shall
execute such documents on behalf of Lessee as Lessee's attorney-in-fact. Lessee
does hereby make, constitute and irrevocably appoint Lessor as Lessee's
attorney-in-fact and in Lessee's name, place and stead, to execute such
documents In accordance with this paragraph 30(b).

herein who seeks to enforce a right hereunder.

the Premises at reasonable times for the purpose of inspecting the same, showing

mutual cancellation thereof, or a termination by Lessor, shall not work a
merger, and shall, at the option of Lessor, terminate all or any existing
subtenancies or may, at the option of Lessor, operate as an assignment to Lessor
of any or all of such subtenancies.

of one party is required to an act of the other party, such consent shall not be
unreasonably withheld.

this 13 day of September, 1996, effective as of the date set forth below:

                                     PARTIES

           P.1 BAYEUX B. BAKER, in his capacity as Executor of the Estate of
Irma C. Kellogg, deceased ("Estate"), is the successor in title to Cloyce Clark,
who is the Lessor under that certain Standard Industrial Lease - Gross, dated

additional 5-year term. All references to the "Lease" are to the Lease as
amended by Amendment No. 1.

                               AMENDMENT TO LEASE

           The parties hereby agree to amend the Lease in the following
particulars only.

           1. The option to extend the Lease granted to Lessee in Amendment No.
1 is amended and replaced by the changed Options described below.

           2. Subject to the provisions of the Lease, Lessor hereby grants to
Lessee five options to extend the term of the Lease for one (1) year periods
beyond the Extended Term of the Lease. The options are for the following terms
(the "Option Terms"):

         Option 1        January 1, 1998 through December 31, 1998
         Option 2        January 1, 1999 through December 31, 1999
         Option 3        January 1, 2000 through December 31, 2000

Premises and its tenancy (if said option to extend is exercised by Lessee), upon
the same terms and conditions as set forth in the Lease. Lessee shall give
Lessor written notice of Lessee's intention to exercise each option to extend no
later than twelve months before the commencement of the Option Term (for

1, 1997 and for Option 2 no later than January 1, 1998).

$24,946 (consisting of $11,106 per month for the 2075 East 5th Street Building
and $13,840 per month for the 2055 East 5th Street Building).

           4. All provisions of the Lease not changed by this Amendment No. 2

         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
competent and qualified to perform such repairs and maintenance. Lessee's duties

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.

certain Lease Agreement (the "Lease"), effective as of September 1, 1986, for
the demise of certain premises commonly known as 609 Myrtle Street, N.W., Grand
Rapids, Michigan (the "Existing Plant").

                  B. Lessee desires to expand its operations by contracting with
Lessor for the construction by Lessor and lease to Lessee, on real estate
commonly known as 600 Webster, N.W., Grand Rapids, Michigan, and adjoining the
Existing Plant, additional space for Lessee's operations (the "New Plant"). The
Existing Plant and New Plant are collectively referred to in the Lease, as the
"Grand Rapids Plant".

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

MUTUAL COVENANTS CONTAINED HEREIN, AMEND THE LEASE AS FOLLOWS:

amended in part to provide that the Lease shall be "for a period commencing

(as hereinafter defined)".

                  2.       Rent.

                           (a) The initial sentence of Paragraph 2 is amended in
                  part to read:

                  "Lessee shall pay rent to Lessor for the Existing Plan for the
                  terms of this Lease, in monthly installments, in advance,
                  without demand, setoff, deduction or counterclaim, as follows:

         Lease, in monthly installments, in advance, without demand, setoff,

                  (o) At the rate of $4.73 per square foot for the ninth and

(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.

located. Lessor may enter upon any premises where Equipment is located and
remove it immediately, without notice or liability to Lessee, upon the
expiration or other termination of the Lease Term.

5. MAINTENANCE AND USE: Lessee agrees it will, at its sole expense: (a) repair
and maintain the Equipment in good condition and working order and supply and
install all replacement parts or other devices when required to so maintain the
Equipment or when required by applicable law or regulation, which parts or
devices shall automatically become part of the Equipment; (b) use and operate
the Equipment in a careful manner in the normal course of its business and only
for the purposes for which it was designed in accordance with the manufacturer's
warranty requirements, and comply with all laws and regulations relating to the
Equipment, and obtain all permits or licenses necessary to install, use or
operate the Equipment; and (c) make no alterations, additions, subtractions,
upgrades or improvements to the Equipment without Lessor's prior written
consent, but any such alterations, additions, upgrades or improvements shall
automatically become part of the Equipment. The Equipment will not be used or
located outside of the United States.

6. NET LEASE; NO EARLY TERMINATION: The Lease is a net lease. Lessee's
obligation to pay all rent and all other amounts payable under the Lease is
absolute and unconditional under any and all circumstances and shall not be
affected by any circumstances of any character including, without limitation,
(a) any setoff, claim, counterclaim, defense or reduction which Lessee may have
at any time against Lessor or any other party for any reason, or (b) any defect
in the condition, design or operation of, any lack of fitness for use of, any
damage to or loss of, or any lack of maintenance or service for any of the
Equipment. Each Schedule is a noncancelable lease of the Equipment described
therein and Lessee's obligation to pay rent and perform all other obligations
thereunder and under the Lease are not subject to cancellation or termination by
Lessee for any reason.

7. NO WARRANTIES BY LESSOR: LESSOR LEASES THE EQUIPMENT AS-IS, WHERE-IS, AND
WITH ALL FAULTS. LESSOR MAKES NO WARRANTIES OR REPRESENTATIONS, EXPRESS OR
IMPLIED, OF ANY KIND AS TO THE EQUIPMENT INCLUDING, WITHOUT LIMITATION: ITS
MERCHANTABILITY; ITS FITNESS FOR ANY PARTICULAR PURPOSE; ITS DESIGN, CONDITION,
QUALITY, CAPACITY, DURABILITY, CAPABILITY, SUITABILITY OR WORKMANSHIP; ITS
NON-INTERFERENCE WITH OR NON-INFRINGEMENT OF ANY PATENT, TRADEMARK, COPYRIGHT OR
OTHER INTELLECTUAL PROPERTY RIGHT; OR ITS COMPLIANCE WITH ANY LAW, RULE,
SPECIFICATION, PURCHASE ORDER OR CONTRACT PERTAINING THERETO. Lessor hereby
assigns to Lessee the benefit of any assignable manufacturer's or supplier's
warranties, but Lessor, at Lessee's written request, will cooperate with Lessee
in pursuing any remedies Lessee may have under such warranties. Any action taken
with regard to warranty claims against any manufacturer or supplier by Lessee
will be at Lessee's sole expense. LESSOR MAKES NO REPRESENTATIONS OR WARRANTIES,
EXPRESS OR IMPLIED, OF ANY KIND AS TO THE FINANCIAL CONDITION OR FINANCIAL
STATEMENTS OF ANY PARTY OR AS TO THE TAX OR ACCOUNTING TREATMENT OR CONSEQUENCES
OF THE LEASE, THE EQUIPMENT OR THE RENTAL PAYMENTS.

8. INSURANCE: Lessee at its sole expense shall at all times keep each item of
Equipment insured against all risks of loss or damage from every cause
whatsoever for an amount not less than the greater of the full replacement value
or the Lessors Cost of such item of Equipment. Lessee at its sole expense shall
at all times carry public liability and property damage insurance in amounts
satisfactory to Lessor protecting Lessee and Lessor from liabilities for
injuries to persons and damage to property of others relating in any way to the
Equipment. All insurers shall be reasonably satisfactory to lessor. Lessee shall
deliver to Lessor satisfactory evidence of such coverage. Proceeds of any
insurance covering damage or loss of the Equipment shall be payable to Lessor as
loss payee and shall, at Lessor's option, be applied toward (a) the replacement,
restoration or repair of the Equipment, or (b) payment of the obligations of
Lessee under the Lease. Proceeds of any public liability or property insurance
shall be payable first to Lessor as additional insured to the extent of its
liability, then to Lessee. If an event of default occurs and is continuing, or
if Lessee fails to make timely payments due under Section 9 hereof, then Lessee
automatically appoints Lessor as Lessee's attorney-in-fact with full power and
authority in the place of Lessee and in the name of Lessee or Lessor to make
claim for, receive payment of, and sign and endorse all documents, checks or
drafts for loss or damage under any such policy. Each insurance policy will
require that the insurer give Lessor at least 30 days prior written notice of
any cancellation of such policy and will require that Lessor's interests remain
insured regardless of any act, error, omission, neglect or misrepresentation of
Lessee. The insurance maintained by Lessee shall be primary without any right of
contribution from insurance which may be maintained by Lessor.

9. LOSS AND DAMAGE: (a) Lessee bears the entire risk of loss, theft, damage or
destruction of Equipment in whole or in part from any reason whatsoever
("Casualty Loss'). No Casualty Loss to Equipment shall relieve Lessee from the
obligation to pay rent or from any other obligation under the Lease.


                                  Page 1 of 4
<PAGE>   2
9. LOSS AND DAMAGE (CONTINUED): In the event of Casualty Loss to any item of
Equipment, Lessee shall immediately notify Lessor of the same and Lessee shall,
it so directed by Lessor, immediately repair the same. If Lessor determines
that any item of Equipment has suffered a Casualty Loss beyond repair ("Lost
Equipment"), then Lessee, at the option of Lessor, shall: (1) Immediately
replace the Lost Equipment with similar equipment in good repair, condition and
working order free and clear of any Liens and deliver to Lessor a bill of sale
covering the replacement equipment, in which event such replacement equipment
shall automatically be Equipment under the Lease; or (2) On the rent payment
date which is at least 30 but no more than 60 days after the date of the
Casualty Loss, pay to Lessor all amounts then due and payable by Lessee under
the Lease for the Lost Equipment plus the Stipulated Loss Value for such Lost
Equipment as of the date of the Casualty Loss. Upon payment by Lessee of all
amounts due under the above clause (2), the lease of the Lost Equipment will
terminate and Lessor shall transfer to Lessee all of Lessor's right, title and
interest in such Equipment on an "as-is, where-is" basis with all faults,
without recourse and without representation or warranty of any kind, express or
implied.
     (b) "Stipulated Loss Value" of any item of Equipment during its Lease Term
equals the present value discounted in arrears to the applicable date at the
applicable SLV Discount Rate of (1) the remaining remits and all other amounts
[including, without limitation, any balloon payment and, as to a terminal rental
adjustment clause ("TRAC") lease, the TRAC value stated in the Schedule, and any
other payments required to be paid by Lessee at the end of the applicable Lease
Term] payable under the Lease for such item on and after such date to the end of
the applicable Lease Term and (2) an amount equal to the Economic Value of the
Equipment. For any item of Equipment, "Economic Value" means the Fair Market
Value of the Equipment at the end of the applicable Lease Term as originally
anticipated by Lessor at the Commencement Date of the applicable Schedule;
provided, that Lessee agrees that such value shall be determined by the books of
Lessor as of the Commencement Date of the applicable Schedule. After the
payment of all rent due under the applicable Schedule and the expiration of the
Lease Term of any item of Equipment, the Stipulated Loss Value of such item
equals the Economic Value of such item. Stipulated Loss Value shall also include
any Taxes payable by Lessor in connection with its receipt thereof. For any item
of Equipment, "SLV Discount Rate" means an interest rate equal to the Prime Rate
in effect on the Commencement Date of the Schedule for such item minus two
percentage points.

10. TAX BENEFITS INDEMNITY. (a) The Lease has been entered into on the basis
that Lessor shall be entitled to such deductions, credits and other tax benefits
as are provided by federal, state and local income tax law to an owner of the
Equipment (the "Tax Benefits") including, without limitation: (1) modified
accelerated cost recovery deductions on each item of Equipment under Section 168
of the Code (as defined below) in an amount determined commencing with the
taxable year in which the Commencement Date of the applicable Schedule occurs,
using the maximum allowable depreciation method available under Section 168 of
the Code, using a recovery period (as defined in Section 168 of the Code)
reasonably determined by Lessor, and using an initial adjusted basis which is
equal to the Lessor's Cost of such item; (2) amortization of the expenses paid
by Lessor in connection with the Lease on a straight-line basis over the term of
the applicable Schedule; and (3) Lessor's federal taxable income Will be subject
to the maximum rate on corporations in effect under the Code as of the
Commencement Date of the applicable Schedule.
     (b) IF on an one or more occasions (1) Lessor shall lose, shall not have or
shall lose the riqht to claim all or any part of the Tax Benefits, (2) there
shall be reduced, disallowed, recalculated or recaptured all or any part of the
Tax Benefits, or (3) all or any part of the Tax Benefits is reduced by a change
in law or regulation (each of the events described in subparagraphs 1, 2 or 3 of
this paragraph (b) will be referred to as a "Tax Loss"), then, upon 30 days
written notice by Lessor to Lessee that a Tax Loss has occurred, Lessee shall
pay Lessor an amount which, in the reasonable opinion of Lessor and after the
deduction of all taxes required to be paid by Lessor with respect to the receipt
of such amount, will provide Lessor with the same after-tax net economic yield
which was originally anticipated by Lessor as of the Commencement Date of the
applicable Schedule.
     (c) A Tax Loss shall occur upon the earliest of: (1) the happening of any
event (such as disposition or change in use of an item of Equipment) which may
cause such Tax Loss; (2) Lessor's payment to the applicable taxing authority of
the tax increase resulting from such Tax Loss; or (3) the adjustment of Lessor's
tax return to reflect such Tax Loss.
     (d) Lessor shall not be entitled to payment under this section for any Tax
Loss caused solely by one or more of the following events: (1) a disqualifying
sale or disposition of an item of Equipment by Lessor prior to any default by
Lessee; (2) Lessor's failure to timely or properly claim the Tax Benefits in
Lessors tax return; (3) a disqualifying change in the nature of Lessor's
business or liquidation thereof; (4) a foreclosure by any person holding through
Lessor a security interest on an item of Equipment which foreclosure results
solely from an act of Lessor; or (5) Lessors failure to have sufficient taxable
income or tax liability to utilize the Tax Benefits.
     (e) "Code" shall mean the Internal Revenue Code of 1986, as amended. For
the purposes of this section 10, the term "Lessor" shall include any affiliate
group (within the meaning of section 1504 of the Code) of which Lessor is a
member for any year in which a consolidated income tax return is filed for such
affiliated Group. Lessee's obligations under this section shall survive the
expiration, cancellation or termination of the Lease.

11. GENERAL TAX INDEMNITY: Lessee will pay, and will defend, indemnify and hold
Lessor harmless on an after-tax basis from, any and all Taxes (as defined below)
and related audit and contest expenses on or relating to (a) any of the
Equipment, (b) the Lease, (c) purchase, acceptance, ownership, lease,
possession, use, operation, transportation, return or other disposition of any
of the Equipment, and (d) rentals or earnings relating to any of the Equipment
or the Lease. 'Taxes' means present and future taxes or other governmental
charges that are not based on the net income of Lessor, whether they are
assessed to or payable BY Lessee or Lessor, including, without limitation (i)
sales, use, excise, licensing, registration, titling, franchise, business and
occupation, gross receipts, stamp and personal property taxes, (ii) levies,
imposts, duties, assessments, charges and withholdings, (iii) penalties, fines,
and additions to tax and (iv) interest on any of the foregoing. Unless Lessor
elects otherwise, Lessor will prepare and file all reports and returns relating
to any Taxes and will pay all Taxes to the appropriate taxing authority. Lessee
will reimburse Lessor for all such payments promptly on request. On or after any
applicable assessment/levy/lien date for any personal property Taxes relating to
any Equipment, Lessee agrees that upon Lessors request Lessee shall pay to
Lessor the personal property Taxes which Lessor reasonably anticipates will be
due, assessed, levied or otherwise imposed on any Equipment during its Lease
Term. If Lessor elects in writing, Lessee will itself prepare and file all such
reports and returns, pay all such Taxes directly to the taxing authority, and
send Lessor evidence thereof. Lessee's obligations under this section shall
survive the expiration, cancellation or termination of the Lease.

12. GENERAL INDEMNITY: Lessee assumes all risk and liability for, and shall
defend, indemnify and keep Lessor harmless on an after-tax basis from, any and
all liabilities, obligations, losses, damages, penalties, claims, actions,
suits, costs and expenses, including reasonable attorney fees and expenses, of
whatsoever kind and nature imposed on, incurred by or asserted against Lessor,
in any way relating to or arising out of the manufacture, purchase, acceptance,
rejection, ownership, possession, use, selection, delivery, lease, operation,
condition, sale, return or other disposition of the Equipment or any part
thereof (including, without limitation, any claim for latent or other defects,
whether or not discoverable by Lessee or any other person, any claim for
negligence, tort or strict liability, any claim under any environmental
protection or hazardous waste law and any claim for patent, trademark or
copyright infringement). Lessee will not indemnify Lessor under this section for
loss or liability arising from events which occur after the Equipment has been
returned to Lessor or for loss or liability caused directly and solely by the
gross negligence or willful misconduct of Lessor. In this section, 'Lessor" also
includes any director, officer, employee, agent, successor or assign of Lessor.
Lessee's obligations under this section shall survive the expiration,
cancellation or termination of the Lease.

13. PERSONAL PROPERTY: Lessee represents and agrees that the Equipment is, and
shall at all times remain, separately identifiable personal properly. Upon
Lessor's request, Lessee shall furnish Lessor a landlord's and/or mortgagee's
waiver and consent to remove all Equipment. Lessor may display notice of its
interest in the Equipment by any reasonable identification. Lessee shall not
alter or deface any such [???] of Lessor's interest.

14. DEFAULT: Each of the following events shall constitute an event of default
under the Lease: (a) Lessee fails to pay any rent or other amount due under the
Lease within ten days of its due date; or (b) Lessee fails to perform or observe
any of its obligations in Sections 8, 18, or 22 hereof; or (c) Lessee fails to
perform or observe any of its other obligations in the Lease for more than 30
days after Lessor notifies Lessee of such failure; or (d) Lessee or any Lessee
affiliate defaults in the payment, performance or observance of any obligation
under any loan, credit agreement or other lease in which Lessor or any
subsidiary (direct or indirect) of Bank One Corporation (which is Lessor's
ultimate parent corporation) is the creditor or lessor; or (e) any statement,
representation or warranty made by Lessee in the Lease, in any Schedule or in
any document, certificate or financial statement in connection with the Lease
proves at any time to have been untrue or misleading in any material respect as
of the time when made; or (f) Lessee becomes insolvent or bankrupt, or Lessee
admits its inability to pay its debts as they mature, or Lessee makes an
assignment for the benefit of creditors, or Lessee applies for, institutes or
consents to the appointment of a receiver, trustee or similar official for
Lessee or any substantial part of its property or any such official is appointed
without Lessee's consent, or Lessee applies for, institutes or consents to any
bankruptcy, insolvency, reorganization, debt moratorium, liquidation, or similar
proceeding relating to Lessee or any substantial part of its property under the
laws of any jurisdiction or any such proceeding is instituted against Lessee
without stay or dismissal for more than 30 days, or Lessee commences any act
amounting to a business failure or a winding up of its affairs, or Lessee ceases
to do business as a doing concern; or (g) with respect to any guaranty, letter
of credit, pledge agreement, security agreement, mortgage, deed of trust, debt
subordination agreement or other credit enhancement or credit support agreement
(whether now existing of hereafter arising) signed or issued by any party in
connection with all or any part of Lessee's obligations under the Lease, the
party signing or issuing any such agreement defaults in its obligations
thereunder or any such agreement shall cease to be in full force and effect or
shall be declared to be null, void, invalid or unenforceable by the party
signing or issuing it; or (h) there shall occur in Lessor's reasonable opinion
any material adverse change in the financial condition, business or operations
of Lessee.


                                  Page 2 of 4
<PAGE>   3

14. DEFAULT (CONTINUED):
As used in this section 14, the term "Lessee" also includes any guarantor
(whether now existing or hereafter arising) of all or any part of Lessee's
obligations under the Lease and/or any issuer of a letter of credit (whether now
existing or hereafter arising) relating to all or any part of Lessee's
obligations under the Lease, and the term "Lease" also includes any guaranty or
letter of credit (whether now existing or hereafter arising) relating to all or
any part of Lessee's obligations under the Lease.

15. REMEDIES. It any event of default exists, Lessor may exercise in any order
one or more of the remedies described in the lettered subparagraphs of this
action, and Lessee shall perform its obligations imposed thereby:
   (a) Lessor may require Lessee to return any or all Equipment as provided in
the Lease.
   (b) Lessor or its agent may repossess any or all Equipment wherever found,
may enter the premises where the Equipment is located and disconnect, render
unusable and remove it, and may use such premises without charge to store or
show the Equipment for sale.
   (c) Lessor may sell any or all Equipment at public or private sale, with or
without advertisement or publication, may re-lease or otherwise dispose of it or
may use, hold or keep it.
   (d) Lessor may require Lessee to pay to Lessor on a date specified by Lessor,
with respect to any or all Equipment (i) all accrued and unpaid rent, late
charges and other amounts due under the Lease on or before such date, plus (ii)
as liquidated damages for loss of a bargain and not as a penalty, and in lieu of
any further payments of rent, the Stipulated Loss Value of the Equipment on such
date, plus (iii) interest at the Overdue Rate on the total of the foregoing
("Overdue Rate" means an interest rate per annum equal to the higher of 18% or
2% over the Prime Rate, but not to exceed the highest rate permitted by
applicable law). The parties acknowledge that the foregoing money damage
calculation reasonably reflects Lessor's anticipated loss with respect to the
Equipment and the related Lease resulting from the event of default. If an event
of default under section 14 (f) of this Master Lease Agreement exists, then
Lessee will be automatically liable to pay Lessor the foregoing amounts as of
the next rent payment date unless Lessor otherwise elects in writing.
   (e) Lessee shall pay all costs, expenses and damages incurred by Lessor
because of the event of default or its actions under this section, including,
without limitation any collection agency and/or attorney fees and expenses, any
costs related to the repossession, safekeeping, storage, repair, reconditioning
or disposition of the Equipment and any incidental and consequential damages.
   (f) Lessor may terminate the Lease and/or any or all Schedules, may sue to
enforce Lessee's performance of its obligations under the Lease and/or may
exercise any other right or remedy then available to Lessor at law or in equity.
   Lessor is not required to take any legal process or give Lessee any notice
before exercising any of the above remedies. None of the above remedies is
exclusive, but each is cumulative and in addition to any other remedy
available to Lessor. Lessor's exercise of one or more remedies shall not
preclude its exercise of any other remedy. No action taken by Lessor shall
release Lessee from any of its obligations to Lessor. No delay or failure on the
part of Lessor to exercise any right hereunder shall operate as a waiver
thereof, nor as an acquiescence in any default, nor shall any single or partial
exercise of any right preclude any other exercise thereof or the exercise of any
other right. After any default, Lessor's acceptance of any payment by Lessee
under the Lease shall not constitute a waiver by Lessor of such default,
regardless of Lessor's knowledge or lack of knowledge at the time of such
payment, and shall not constitute a reinstatement of the Lease if the Lease has
been declared in default by Lessor, unless Lessor has agreed in writing to
reinstate the Lease and to waive the default.

  If Lessor actually repossesses any Equipment, then it will use commercially
reasonable efforts under the then current circumstances to attempt to mitigate
its damages; provided, that Lessor shall not be required to sell, re-lease or
otherwise dispose of any Equipment prior to Lessor enforcing any of the remedies
described above. Lessor may sell or re-lease the Equipment in any manner it
chooses, free and clear of any claims or rights of Lessee and without any duty
to account to Lessee with respect thereto except as provided below. If Lessor
actually sells or re-leases the Equipment, it will credit the net proceeds of
any sale of the Equipment, or the net present value (discounted at the then
current Prime Rate) of the rents payable under any new lease Of the Equipment,
against and up to (but not exceeding) the Stipulated Loss Value of the Equipment
and any other amounts Lessee owes Lessor, or will reimburse Lessee for and up to
(but not exceeding) Lessee's payment thereof. The term "net" as used above shall
mean such amount after deducting the costs and expenses described in clause (e)
above of this section. If Lessor elects in writing not to sell or re-lease any
Equipment, it will similarly credit or reimburse Lessee for Lessor's reasonable
estimate of such Equipment's Fair Market Value.

16. LESSOR'S RIGHT TO PERFORM: If Lessee fails to make any payment under the
Lease or fails to perform any of its other agreements in the Lease including,
without limitation, its agreement to provide insurance coverage as stated in the
Lease), Lessor may itself make such payment or perform such agreement, and the
amount of such payment and the amount of the expenses of Lessor incurred in
connection with such payment or performance shall be deemed to be additional
rent, payable by Lessee on demand.

17. FINANCIAL REPORTS: Lessee agrees to furnish to Lessor: (a) annual financial
statements setting forth the financial condition and results of operation of
Lessee (financial statements shall include the balance sheet, income statement
and changes in financial position and all notes thereto) within 120 days of the
end of each fiscal year of Lessee; (b) quarterly financial statements setting
forth the financial condition and results OF operation of Lessee within 60 days
of the end of each of the first three fiscal quarters of Lessee; and (c) such
other financial information as Lessor may from time to time reasonably request
including, without limitation, financial reports filed by Lessee with federal or
state regulatory agencies. All such financial information shall be prepared in
accordance with generally accepted accounting principles. If Lessee fails to
furnish the annual financial statements to Lessor within 30 days of Lessor's
written request, then Lessor may, at its option, charge Lessee a non-performance
fee equal to all the rentals due under the Lease for the then current month
(unless otherwise prohibited by law) and such fees shall be deemed to be
additional rent, payable by Lessee on demand.

18. NO CHANGES IN LESSEE: Lessee shall not: (a) liquidate, dissolve or suspend
business; (b) sell, transfer or otherwise dispose of all or a majority of its
assets, except that Lessee may sell its inventory in the ordinary course of its
business; (c) enter into any merger, consolidation or similar reorganization
unless it is the surviving corporation; (d) transfer all or any substantial part
of its operations or assets outside of the United States of America; or (e)
without 30 days advance written notice to Lessor, change its name or chief place
of business. Lessee shall at all times maintain a tangible net worth which is no
less than the greater of 75% of its tangible net worth as of the date of the
Master Lease Agreement or 75% of its highest tangible net worth thereafter.

19. LATE CHARGES: If any rent or other amount payable under the Lease is not
paid when due, then as compensation for the administration and enforcement of
Lessee's obligation to make timely payments, Lessee shall pay with respect to
each overdue payment on demand an amount equal to the greater of fifteen dollars
($15.60) or five percent (5%) of the each overdue payment (but not to exceed the
highest late charge permitted by applicable LAW) plus any collection agency
fees and expenses.

20. NOTICES; POWER OF ATTORNEY: (a) Service of all notices under the Lease shall
be sufficient if given personally or couriered or mailed to the party involved
at its respective address set forth herein or at such other address as such
party may provide in writing from time to time. Any such notice mailed to such
address shall be effective three days after deposit in the United States mail
with postage prepaid. (b) With respect to any power of attorney covered by the
Lease, the powers conferred on Lessor thereby: are powers coupled with an
interest; are irrevocable; are solely to protect Lessor's interests under the
Lease; and do not impose any duty on Lessor to exercise such powers. Lessor
shall be accountable solely for amounts it actually receives as a result of its
exercise of such powers.

21. ASSIGNMENT BY LESSOR: Lessor and any assignee of Lessor, with or without
notice to or consent of Lessee, may sell, assign, transfer or grant a security
interest in all or any part of Lessor's rights, obligations, title or interest
in the Equipment, the Lease, any Schedule or the amounts payable under the Lease
or any Schedule to any entity ("transferee"). The transferee shall succeed to
all of Lessor's rights in respect to the Lease (including, without limitation,
all rights to insurance and indemnity protection described in the Lease). Lessee
agrees to sign any acknowledgement and other documents reasonably requested by
Lessor or the transferee in connection with any-such transfer transaction.
Lessee, upon receiving notice of any such transfer transaction, shall comply
with the terms and conditions thereof. Lessee agrees that it shall not assert
against any transferee any claim, defense, setoff, deduction or counterclaim
which Lessee May now or hereafter be entitled to assert against Lessor. Unless
otherwise agreed in writing, the transfer transaction shall not relieve Lessor
of any of its legations to Lessee under the Lease and Lessee agrees that the
transfer transaction shall not be construed as being an assumption of such
obligations by the transferee.

22. NO ASSIGNMENT, SUBLEASE OR LIEN BY LESSEE: LESSEE SHALL NOT, DIRECTLY OR
INDIRECTLY, (a) MORTGAGE, ASSIGN, SELL. TRANSFER, OR OTHERWISE DISPOSE OF THE
LEASE OR ANY INTEREST THEREIN OR THE EQUIPMENT OR ANY PART. THEREOF, OR (b)
SUBLEASE, RENT, LEND OR TRANSFER POSSESSION OR USE OF THE EQUIPMENT OR ANY PART
THEREFOR TO ANY PARTY, OR (c) CREATE, INCUR, GRANT, ASSUME OR ALLOW TO EXIST ANY
LIEN ON THE LEASE, ANY SCHEDULE, THE EQUIPMENT OR ANY PART THEREOF.


                                  Page 3 of 4
<PAGE>   4

23. EXPIRATION OF LEASE TERM: (a) At east 90 days (or earlier if otherwise
specified), but no more than 270 days prior to expiration of the Lease Term of
each Schedule, Lessee shall give Lessor written notice of its electing one of
the following options for all (but not less than all) of the Equipment covered
by such Schedule: return the Equipment under clause (b) below; or purchase the
Equipment under clause (c) below. The election of an option shall be
irrevocable. If Lessee fails to give timely notice of its election, it shall be
deemed to have elected to return the Equipment.
     (b) If Lessee elects or is deemed to have elected to return the Equipment
at the expiration of the Lease Term of a Schedule or if Lessee is obligated at
any time to return the Equipment, then Lessee shall, at its sole expense and
risk, deinstall, disassemble, pack, crate, insure and return the Equipment to
Lessor (all in accordance with applicable industry standards) at any location in
the continental United States of America selected by Lessor. The Equipment shall
be in the same condition as when received by Lessee, reasonable wear, tear and
depreciation resulting from normal and proper use excepted (or, if applicable,
in the condition set forth in the Lease or the Schedule), shall be in good
operating order and maintenance as required by the Lease, shall be certified as
being eligible for any available manufacturer's maintenance program, shelf be
free and clear of any Liens as required by the Lease, shall comply with all
applicable laws and regulations and shall include all manuals, specifications,
repair and maintenance records and similar documents. Until Equipment is
returned as required above, all terms of the Lease shall remain in full force
and effect including, without limitation, obligations to pay rent and insure the
Equipment; provided, that after the expiration of any Schedule and before Lessee
has completed its return of the Equipment or its purchase option (if elected),
the term of the lease of the Equipment covered by such Schedule shall be
month-to-month or such shorter period as may be specified by Lessor.
     (c) If Lessee gives Lessor timely notice of its election to purchase
Equipment, then on the expiration date of the applicable Schedule Lessee shall
purchase all (but not less than all) of the Equipment and shall pay to Lessor
the Fair Market Value of the Equipment plus all Taxes (other than income taxes
on lessor's gains on such sale), costs and expenses incurred or paid by lessor
in connection with such sale plus all accrued but unpaid amounts due with
respect to the Equipment and/or the Schedule. The Stipulated Loss Value or
Economic Value of any item of Equipment shall have no bearing or influence on
the determination of Fair Market Value under this clause (c). Upon payment in
full of the above amounts, and if no default has occurred and is continuing
under the Lease, Lessor shall transfer title to such Equipment to Lessee "as-is,
where-is" with all faults and without recourse to Lessor and without any
representation or warranty of any kind whatsoever by Lessor, express or implied.
     (d) For purposes of the purchase option of the Lease, the determination of
the Fair Market Value of any Equipment shall be determined (1) without deducting
any costs of dismantling or removal from the location of use, (2) on the
assumption that the Equipment is in the condition required by the applicable
return and maintenance provisions of the Lease and is free and clear of any
Liens as required by the Lease, and (3) shall be determined by mutual agreement
of Lessee and Lessor or, if Lessor and Lessee are not able to agree on such
value, by the Appraisal Procedure. "Appraisal Procedure" means the determination
of Fair Market Value by an independent appraiser acceptable to Lessor and
Lessee, or, if the parties are unable to agree on an acceptable appraiser, by
averaging the valuation (disregarding the one which differs the most from the
other two) of three independent appraisers, the first appointed by Lessor, the
second appointed by Lessee and the third appointed by the first two appraisers.

4. FINANCING TERM. The Base Term of this Schedule shall be THIRTY-SIX (36)

(d) Security Deposit: $ N/A. On the Acceptance Date, Lessee shall pay Lessor
said Security Deposit which shall be held in accordance with paragraph 6 below.

6. SECURITY INTEREST. This Schedule is intended to be a secured debt financing
transaction, not a true lease. See Paragraph 7 below regarding Lessee's

of all Secured Obligations (defined in Paragraph 8 below) and to induce Lessor
to extend credit from time to time to Lessee (under the Lease or otherwise),
Lessee hereby grants to Lessor a first priority security interest in all of
Lessee's right, title and interest in the Equipment, whether now existing or

apply all or any part of any Security Deposit to cure any default of Lessee
under the Lease. If upon final termination of this Schedule, Lessee has
fulfilled all of the terms and conditions hereof, then Lessor shall pay to
Lessee upon Lessee's written request any remaining balance of the Security
Deposit for this Schedule, without interest.

7. TITLE TO EQUIPMENT; FIRST PRIORITY LIEN. Lessee represents, warrants and
agrees: that Lessee currently is the lawful owner of the Equipment; that good
and marketable title to the Equipment shall remain with Lessee at all times;
that Lessee has granted to Lessor a first priority security interest in the
Equipment and all Proceeds; and that the Equipment and all Proceeds are, and at
all times shall be, free and clear of any Liens other than Lessor's security
interest therein. Lessee at its sole expense will protect and defend Lessor's
first priority security interest in the Equipment against all claims and demands
whatsoever.

8. CERTAIN DEFINITIONS. "Secured Obligations" means (a) all payments and other
obligations of Lessee under or in connection with this Schedule, and (b) all
payments and other obligations of Lessee (whether now existing or hereafter
incurred) under or in connection with the Master Lease and all present and
future Lease Schedules thereto, and (c) all other leases, indebtedness,
liabilities and/or obligations of any kind (whether now existing or hereafter
incurred, absolute or contingent, direct or indirect) of Lessee to Lessor or to
any affiliate of either Lessor or BANK ONE CORPORATION. "Proceeds" means all

Lease to the extent it relates to this Schedule as of such specified date, plus
(b) the remaining principal balance due and payable by Lessee under this

specified date; provided, that the foregoing calculation shall not exceed the
maximum amount which may be collected by Lessor from Lessee under applicable law
in connection with enforcement of Lessor's rights under this Schedule and the

    3.3 Examination Fees. Borrower agrees to pay to Lender an examination fee in
the amount set forth on the Schedule in connection with each audit or

lending transaction, shall be payable by Borrower as, and shall be deemed to be,
additional interest and for such purposes only, the agreed upon and "contracted
for rate of interest" of this lending transaction shall be deemed to be

    It is the intent of the parties to comply with the usury laws of the State

notwithstanding any provisions to the contrary in this Agreement, or in any of
the documents securing payment hereof or otherwise relating hereto, in no event
whatsoever shall this Agreement or such documents require the payment or permit
the collection of interest or other charges in the nature of interest in excess
of the maximum contract rate permitted by the Applicable Usury Law (the "Maximum
Interest Rate"). In the event (a) any such excess of interest otherwise would be
contracted for, charged or received from Borrower or otherwise in connection
with the Loans evidenced hereby, (b) the maturity of the Obligations is
accelerated in whole or in part, or (c) all or part of the Obligations shall be
prepaid, so that under any of such circumstances the amount of interest
contracted for, shared or received in connection with the Loans evidenced
hereby, would exceed the Maximum Interest Rate, then in any such event (1) the
provisions of this Section 3.4 shall govern and control, (2) neither Borrower
nor any other person or entity now or hereafter liable for the payment of the
Obligations shall be obligated to pay the amount of such interest to the extent
that it is in excess of the Maximum Interest Rate, (3) any such excess which may
have been collected shall be either be applied as a credit against the then
unpaid principal amount of the Obligations or refunded to Borrower, at Lender's
option, and (4) the effective rate of interest shall be automatically reduced to
the Maximum Interest Rate. It is further agreed, without limiting the generality
of the foregoing, that to the extent permitted by the Applicable Usury Law, (x)
all calculations of interest which are made for the purpose of determining
whether such rate would exceed the Maximum Interest Rate shall be made by
amortizing, prorating, allocating and spreading during the period of the full
stated term of the Loans evidenced hereby, all interest at any time contracted
for, charged or received from Borrower or otherwise in connection with such
Loans; and (y) in the event that the effective rate of interest on the Loans
should at any time exceed the Maximum Interest Rate, such excess interest that
would otherwise have been collected had there been no ceiling imposed by the
Applicable Usury Law shall be paid to Lender from time to time, if and when the
effective interest rate on the Loans otherwise falls below the Maximum Interest
Rate, to the extent that interest paid to the date of calculation does not
exceed the Maximum Interest Rate, until the entire amount of interest which
would otherwise have been collected had there been no ceiling imposed by the
Applicable Usury Law has been paid in full. Borrower further agrees that should
the Maximum Interest Rate be increased at anytime hereafter because of a change
in the Applicable Usury Law, such increases shall apply to all indebtedness
evidenced hereby regardless of when incurred; but, again to the extent not


                                      -3-

prohibited by the Applicable Usury Law, should the Maximum Interest Rate be
decreased because of a change in the Applicable Usury Law, such decreases shall
not apply to the indebtedness evidenced hereby regardless of when incurred.

Account bank or the Dominion Account bank, pursuant to Section 7.3, and this
provision shall apply regardless of the amount of the Obligations outstanding or

credit Borrower's account for the amount of any item of payment which is
unsatisfactory to Lender in its sole discretion and Lender may charge Borrower's
loan account for the amount of any item of payment which is returned to Lender
unpaid.

Collateral shall, at the direction of Lender, be deposited by Borrower into a
lockbox account, or such other "blocked account" as Lender may require (each, a
"Blocked Account") pursuant to an arrangement with such bank as may be selected

an irrevocable letter of instruction directing said bank to transfer such funds
so deposited to Lender, either to any account maintained by Lender at said bank
or by wire transfer to appropriate account(s) of Lender. All funds deposited in
a Blocked Account shall immediately become the sole property of Lender and
Borrower shall obtain the agreement by such bank to waive any offset rights
against the funds so deposited. Lender assumes no responsibility for any Blocked
Account arrangement, including without limitation, any claim of accord and
satisfaction or release with respect to deposits accepted by any bank

Account") and Borrower shall deposit all proceeds of Receivables and all cash
proceeds of any sale of Inventory or, to the extent permitted herein, Equipment

lieu of depositing same to Blocked Accounts.

credited (conditioned upon final collection) to Borrower's loan account one (1)
Business Day after Lender's receipt thereof.

account of advances, charges, expenses and payments made pursuant to this
Agreement. Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications; of
payments made and correction of manifest error in calculation), unless Borrower
notifies Lender in writing to the contrary within sixty (60) days after each
account is rendered, describing the nature of any alleged errors or omissions.

Lender may deliver a notice to Borrower, such notice to be delivered within

ending December 31, 1997, requiring Borrower to make a prepayment to be applied

Section 7.7 are strictly at the sole option of Lender. All payments required
hereunder shall be paid by Borrower within thirty (30) days following the
delivery by Lender of a written demand for such payment hereunder. Failure of
Lender to demand or require a Required Excess Cash Flow Payment with respect to
a particular fiscal year of Borrower or the failure of Lender to demand a
payment of the entire Required Excess Cash Flow Payment with respect to a
particular fiscal year of Borrower shall not constitute a waiver of Lender's
right to demand a payment of the entire Required Excess Cash Flow Payment for
any subsequent fiscal year of Borrower. All amounts paid pursuant to this
Section 7.7 shall be applied first against the outstanding principal balance of
Term Loan A, in the inverse order of the maturity of payments accruing under

order of the maturity of payments accruing under the Capex Note, until all
amounts due under the Capex Note have been paid in full. No fee or other form of
prepayment premium shall be applied to any payments required under this Section
7.7. No Termination Fee, Make Whole Premium or other form of prepayment premium
shall be applied to any payments made under this Section 7.7.

actual damages.

any part thereof, is based and service of a summons and complaint on an officer

shall not be waived, tolled, or extended except by a specific written agreement
of Lender. This provision shall survive any termination of this Loan Agreement
or any other agreement.

any indirect, special, incidental or consequential damages in connection with
any breach of contract, tort or other wrong relating to this Agreement or the
Obligations or the establishment, administration or collection thereof

interruption, or the like), whether such damages are foreseeable or
unforeseeable, even if LENDER has been advised of the possibility of such

reason, including, but not limited to, commission of a tort or violation of any
contractual duty or duty implied by law. Borrower agrees that unless such notice
is fully given as promptly as possible (and in any event within thirty (30)
days) after Borrower has knowledge, or with the exercise of reasonable diligence
should have had knowledge, of any such action, inaction or defense, Borrower
shall not assert, and Borrower shall be deemed to have waived, any claim or
defense arising therefrom.

before the beginning of the pay period in which Elective Deferral Contributions
are to begin. (See Item N and Section 3.01.)

distributed before the Member's separation from service, death, the date the
Member becomes Totally Disabled, before the events described in the last

ENTRY BREAK means, when the elapsed time method is used, a one-year Period of
Severance beginning on an Employee's Severance Date. An Employee incurs an Entry
Break on the last day of a one-year Period of Severance.

When the hours method is used, Entry Break is defined in Item K. However, if the
Adoption Agreement - Plus is not used, Entry Break means an Entry Service Period
in which an Employee does not have more than one-half of the Hours of Service
required in Item K for a year of Entry Service. An Employee incurs an Entry
Break on the last day of the Entry Service Period in which he has an Entry
Break.

ENTRY DATE means the date an Employee first enters the Plan as an Active Member.
(See Item L and Section 2.01.)

ENTRY SERVICE means an Employee's service as defined in Item K. Entry Service
shall include service with a Controlled Group member while we are both members
of the Controlled Group.

Entry Service shall include a Period of Military Duty. If the elapsed time
method is used, the entire Period of Military Duty shall be included to the
extent it has not already been counted as Entry Service. If the hours method is
used, an Hour of Service shall be credited (without regard to the 501 Hours of
Service limitation) for each hour the Employee would normally have been


                                      -8-


ARTICLE I

<PAGE>   9
scheduled to work for us during such Period of Military Duty to the extent such
hour has not already been counted for purposes of Entry Service.

If the elapsed time method is used and an Employee has more than one countable
Period of Service, Entry Service shall be determined by adjusting his Hire Date
so that the Employee has one continuous period of Entry Service equal to the
total of all his countable Periods of Service. This period of Entry Service
shall be expressed as whole years (on the basis that 365 days equal one year)
and days.

If the elapsed time method is used, Entry Service shall include a Period of
Severance (service spanning rule) if

(a)      the Period of Severance immediately follows a period during which an
         Employee is not absent from work and ends within twelve months, or

(b)      the Period of Severance immediately follows a period during which an
         Employee is absent from work for any reason other than quitting, being
         discharged, or retiring (such as a leave of absence or layoff) and ends
         within twelve months of the date he was first absent.

If the hours method is used and the Entry Service Period shifts to the Plan
Year, an Employee will be credited with two years of Entry Service if he has the
Hours of Service required for a year of Entry Service in both his first and
second Entry Service Periods.

If the method of crediting Entry Service changes, the provisions of Section 9.13
shall apply.

ENTRY SERVICE PERIOD means the period defined in Item K. However, if the
Adoption Agreement - Plus is not used, Entry Service Period means a
12-consecutive month period beginning on an Employee's Hire Date and each
following 12-consecutive month period beginning on an anniversary of that Hire
Date. If an Employee has a Rehire Date, a new Entry Service Period shall begin
on that date in the same manner as if it were a Hire Date.

ERISA means the Employee Retirement Income Security Act of 1974.

FAMILY MEMBER means an individual described in Code Section 414(q)(6)(B). FISCAL
YEAR means our taxable year.  (See Item F.)

FORFEITURE means the part, if any, of a Member's Account which is forfeited.
(See Section 3.04.)

FORFEITURE DATE means, as to a Member, the date the Member incurs five
consecutive Vesting Breaks. Before the first Yearly Date in 1985, the Forfeiture
Date is the date the Member incurs a Vesting Break.

HIGHLY COMPENSATED EMPLOYEE means a highly compensated active Employee or a
highly compensated former Employee.


                                      -9-


ARTICLE I

<PAGE>   10
A highly compensated active Employee means any Employee who performs service for
us during the determination year and who, during the look-back year:

(a)      received compensation from us in excess of $75,000 (as adjusted
         pursuant to Code Section 415(d));

(b)      received compensation from us in excess of $50,000 (as adjusted
         pursuant to Code Section 415(d)) and was a member of the top-paid group
         for such year; or

(c)      was an officer of ours and received compensation during such year that
         is greater than 50 percent of the dollar limitation in effect under
         Code Section 415(b)(1)(A).

The term Highly Compensated Employee also means:

(d)      Employees who are both described in the preceding sentence if the term
         "determination year" is substituted for the term "look-back year" and
         the Employee is one of the 100 Employees who received the most
         compensation from us during the determination year; and

(e)      Employees who are 5 percent owners at any time during the look-back
         year or determination year.

If no officer has satisfied the compensation requirement of (c) above during
either a determination year or look-back year, the highest paid officer for such
year shall be treated as a Highly Compensated Employee.

For this purpose, the determination year shall be the Plan Year. The look-back
year shall be the twelve-month period immediately preceding the determination
year.

A highly compensated former Employee means any Employee who separated from
service (or was deemed to have separated) prior to the determination year,
performs no service for us during the determination year, and was a highly
compensated active Employee for either the separation year or any determination
year ending on or after the Employee's 55th birthday.

If an Employee is, during a determination year or look-back year, a family
member of either a 5 percent owner who is an active or former Employee or a
Highly Compensated Employee who is one of the 10 most highly compensated
Employees ranked on the basis of compensation paid by us during such year, then
the family member and the 5 percent owner or top-ten highly compensated Employee
shall be aggregated. In such case, the family member and 5 percent owner or
top-ten highly compensated Employee shall be treated as a single Employee
receiving compensation and Plan contributions or benefits equal to the sum of
such compensation and contributions or benefits of the family member and 5
percent owner or top-ten highly compensated Employee. For purposes of this
definition, family member includes the spouse, lineal ascendants and descendants
of the Employee or former Employee and the spouses of such lineal ascendants and
descendants.

The determination of who is a Highly Compensated Employee, including the
determinations of the number and identity of Employees in the top-paid group,
the top 100 Employees, the number of Employees treated as officers and the
compensation that is considered, will be made in accordance with Code Section
414(q) and the regulations thereunder.

HIRE DATE means the date an Employee first performs an Hour of Service.

HOUR OF SERVICE means, for the elapsed time method of crediting service in this
Plan, each hour for which an Employee is paid, or entitled to payment, for
performing duties for us. Hour of Service means, for the hours method of
crediting service in this Plan, the following:

(a)      Each hour for which an Employee is paid, or entitled to payment, for
         performing duties for us during the applicable service period.

(b)      Each hour for which an Employee is paid, or entitled to payment, by us
         on account of a period of time in which no duties are performed
         (irrespective of whether the employment relationship has terminated)
         due to vacation, holiday, illness, incapacity (including disability),
         layoff, jury duty, military duty, or leave of absence. Notwithstanding
         the preceding provisions of this subparagraph (b) no credit shall be
         given to the Employee

         (1)      for more than 501 Hours of Service under this subparagraph (b)
                  on account of any single continuous period in which the
                  Employee performs no duties (whether or not such period occurs
                  in a single service period); or

         (2)      for an Hour of Service for which the Employee is directly or
                  indirectly paid, or entitled to payment, on account of a
                  period in which no duties are performed if such payment is
                  made or due under a plan maintained solely for the purpose of
                  complying with applicable worker's or workmen's compensation,
                  or unemployment compensation or disability insurance laws; or

         (3)      for an Hour of Service for a payment which solely reimburses
                  the Employee for medical or medically related expenses
                  incurred by him.

For purpose of this subparagraph (b), a payment shall be deemed to be made by or
due from us regardless of whether such payment is made by or due from us
directly or indirectly through, among others, a trust fund or insurer, to which
we contribute or pay premiums and regardless of whether contributions made or
due to the trust fund, insurer, or other entity are for the benefit of
particular employees or are on behalf of a group of employees in the aggregate.

(c)      Each hour for which back pay, irrespective of mitigation of damages, is
         either awarded or agreed to by us. The same Hour of Service shall not
         be credited under both this subparagraph (c) and under either
         subparagraph (a) or (b) above. Crediting of Hours of Service for back
         pay awarded or agreed to with respect to periods described in
         subparagraph (b) above shall be subject to the limitations set forth in
         that subparagraph.

The crediting of Hours of Service above shall be applied under the rules of
paragraphs (b) and (c) of the Department of Labor Regulation 2530.200b-2
(including any interpretations or opinions implementing said rules); which
rules, by this reference, are specifically incorporated in full within this
Plan. The reference to paragraph (b) applies to the special rule for determining
hours of service for reasons other than the performance of duties such as
payments calculated (or not calculated) on the basis of units of time and the
rule against double credit. The reference to paragraph (c) applies to the
crediting of hours of service to service periods.

Hours of Service shall be credited for employment with any other employer
required to be aggregated with us under Code Section 414(b), (c), (m) or (o) and

contributions. Hours of Service shall also be credited for any individual who is
considered an employee for purposes of this Plan pursuant to Code Section 414(n)
or Code Section 414(o) and the regulations thereunder.

Solely for purposes of determining whether a one-year break in service has
occurred for entry or vesting purposes, during a Parental Absence an Employee
shall be credited with the Hours of Service which would otherwise have been
credited to the Employee but for such absence, or in any case in which such
hours cannot be determined, eight Hours of Service per day of such absence. The
Hours of Service credited under this paragraph shall be credited in the service
period in which the absence begins if the crediting is necessary to prevent a
break in service in that period; or in all other cases, in the following service
period.

INACTIVE MEMBER means a former Active Member who has an Account. (See Section
2.02.)

Level shall be adjusted based upon the ratio of the Member's Pay from us to his
total pay from us and the Controlled Group member.

INVESTMENT FUND means that part of the Plan assets held under the Trust,
excluding the cash values of any Insurance Policy. (See Article VIIIA.)

If our Plan is not trusteed, Investment Fund means the total assets held under

Investment Fund shall be valued at current fair market value as of the last day
of the last calendar month ending in the Plan Year and, at the discretion of the
Insurer, may be valued more frequently. The valuation shall take into
consideration investment earnings credited, expenses charged, payments made, and
changes in the values of the assets held in the fund.

Member shall be credited with its share of the gains and losses of the
Investment Fund. That part of a Member's Account invested in a funding
arrangement which establishes an account or accounts for such Member thereunder
shall be credited with the gain or loss from such account or accounts. That part
of a Member's Account which is invested in other funding arrangements shall be
credited with a proportionate share of the gain or loss of such investments. The

substantially full time basis for a period of at least one year, and such
services are of a type historically performed by employees in the business field
of the recipient employer. Contributions or benefits provided a Leased Employee
by the leasing organization which are attributable to service performed for the
recipient employer shall be treated as provided by the recipient employer.

unless the qualified election procedures of Article VI are met. Even if the
Member is an Employee on his Normal Retirement Date, he may choose to have
retirement benefits begin on such date. An earlier Retirement Date may apply if

shall apply, except that in applying such rules, the term "family" shall include
only the spouse of the Member and any lineal descendants of the Member who have

Level if this Plan provides for permitted disparity), the limitation shall be
prorated among the affected individual's Pay as determined under this definition
prior to the application of this limitation.

consolidation or transfer of assets or liabilities, this Plan is a continuation
of a plan which was qualifiable under Code Section 401(a), that plan shall be a
Prior Plan. If, with the approval of any governmental agency to which it is
subject, the assets of a terminated plan of ours which was qualified under Code
Section 401(a) are transferred to this Plan, that terminated plan shall be
deemed to be the Prior Plan.

PRIOR PLAN ASSETS means the assets accumulated under the Prior Plan which have

         any combination of vacation, holiday, sickness, disability, leave of
         absence, or layoff.

Solely to determine whether a one-year Period of Severance has occurred for
entry or vesting purposes for an Employee who is absent from service beyond the

VESTED ACCOUNT means, on any date, the vested part of a Member's Account
(including the cash values of any insurance coverage on his life under this
Plan). If the Member's Vesting Percentage is 100%, the Vested Account equals his
Account. If the Member's Vesting Percentage is not 100%, the Vested Account
equals the sum of (a) and (b) below:

(a)      The part of the Member's Account resulting from vested Employer
         Contributions made before any prior Forfeiture Date, and from Member
         Contributions and Rollover Contributions. The Member is fully (100%)
         vested in this part of his Account.

(b)      The balance of the Member's Account in excess of the amount in (a)
         above multiplied by his Vesting Percentage.

         If the Member has withdrawn any part of his Account resulting from our
         Contributions, other than vested Employer Contributions included in (a)
         above, the amount determined under this subparagraph (b) shall be equal
         to P(AB + D) - D as defined below:

         P        The Member's Vesting Percentage.

         AB       the balance of the Member's Account in excess of the amount in

                  other than our vested Contributions included in (a) above.

VESTING BREAK means, when the elapsed time method is used, a one-year Period of
Severance. An Employee incurs a Vesting Break on the last day of a one-year
Period of Severance.

When the hours method is used, Vesting Break is defined in Item V. However, if
the Adoption Agreement - Plus is not used, Vesting Break means a Vesting Service
Period in which an Employee does not have more than one-half of the Hours of
Service required in Item V for a year of Vesting Service. An Employee incurs a
Vesting Break on the last day of the Vesting Service Period in which he has a
Vesting Break.

VESTING PERCENTAGE means the Vesting Percentage of a Member determined under
Item U. If the computation of Vesting Percentage is changed (whether directly or
indirectly), a Member's Vesting Percentage as of the day before the change shall
not be reduced due to the change. Indirect changes include, but are not limited
to, changes in Early Retirement Date requirements or the method of crediting
Vesting Service. The provisions of Section 9.01 regarding changes in the
computation of Vesting Percentage shall apply.

VESTING SERVICE means an Employee's service determined under Item V. Vesting
Service is subject to the modifications selected under that item. Vesting
Service shall include service with a Controlled Group member while we are both
members of the Controlled Group.

provisions, service before the date the Prior Plan became subject to ERISA may
be disregarded if such service


ARTICLE I                             -19-
<PAGE>   20
would have been disregarded under the Prior Plan break in service rules as in
effect on the day before such date.

VESTING SERVICE shall include a Period of Military Duty. If the elapsed time
method is used, the entire Period of Military Duty shall be included to the
extent it has not already been counted as Vesting Service. If the hours method
is used, an Hour of Service shall be credited (without regard to the 501 Hours
of Service limitation) for each hour the Employee would normally have been
scheduled to work for us during such Period of Military Duty, to the extent such
hour has not already been credited as Vesting Service.

If the elapsed time method is used and the Employee has more than one countable
Period of Service or if all or a part of a Period of Service is not counted,
Vesting Service shall be determined by adjusting his Hire Date so that the
Employee has one continuous period of Vesting Service equal to the total of all
his countable Periods of Service. This period of Vesting Service shall be
expressed as whole years (on the basis that 365 days equal one year) and days.

If the elapsed time method is used, Vesting Service shall include a Period of
Severance (service spanning rule) if

(a)      the Period of Severance immediately follows a period during which an
         Employee is not absent from work and ends within twelve months, or

(b)      the Period of Severance immediately follows a period during which an
         Employee is absent from work for any reason other than quitting, being
         discharged, or retiring (such as a leave of absence or layoff) and ends
         within twelve months of the date he was first absent.

If the Prior Plan applied the rule of parity before the first Yearly Date in
1985, an Employee's Vesting Service, accumulated before a Vesting Break which
occurred before that date, shall be excluded according to the Prior Plan
provisions if (a) his Vesting Percentage is zero, and (b) his latest period of
consecutive Vesting Breaks equals or exceeds his prior Vesting Service
(disregarding any Vesting Service that was excluded because of a previous period
of Vesting Breaks).

For a Member who is not credited with an Hour of Service on or after the first
Yearly Date in 1985, Vesting Service accrued before such date and before an age
greater than 18 (before the beginning of the Vesting Service Period in which he
attained that age, when the hours method is used) shall be excluded if the Prior
Plan excluded such service.

If the method of crediting Vesting Service changes, the provisions of Sections
9.01 and 9.13 shall apply.

VESTING SERVICE PERIOD means the period defined in Item V. However, if the
Adoption Agreement - Plus is not used, Vesting Service Period means a
12-consecutive month period ending on the last day of the Plan Year.

SECTION 2.01  -  ACTIVE MEMBERSHIP.

An Employee shall first become an Active Member (begin active participation in
the Plan) on the earliest date specified in Item L on which he is an Eligible
Employee and has met all of the entry requirements selected in Item K. This date
is the Member's Entry Date.

Each Employee who was an active member under the Prior Plan on the day before
the Restatement Date shall become an Active Member under this Plan on the
Restatement Date if he is still an Eligible Employee. The Member's entry date
under the Prior Plan is deemed to be his Entry Date under this Plan.

If a person has been an Eligible Employee who has met all of the entry
requirements selected in Item K but is not an Eligible Employee on the date
which would have been his Entry Date, he shall become an Active Member on the
date he again becomes an Eligible Employee. This date is the Member's Entry
Date.

A former Active Member shall reenter the Plan as an Active Member on the date he
again performs an Hour of Service as an Eligible Employee. This date is the
Member's Reentry Date. An Inactive Member ceases to be an Inactive Member on his
Reentry Date.

A Member's benefits under this Plan shall not be duplicated because of more than
one period as an Active Member.

SECTION 2.02  -  CEASING ACTIVE MEMBERSHIP.

An Active Member shall become an Inactive Member (stop accruing benefits under
the Plan) on the earlier of the following:

         Retirement Date).

(b)      The effective date of complete termination of the Plan under Article
         VII.

An Employee or former Employee who was an inactive member under the Prior Plan

SECTION 2.03  -  ADOPTING EMPLOYERS  -  SEPARATE PLANS.

If Item Z(1)(a)(i) of the Adoption Agreement - Plus is selected, each Adopting
Employer listed in Item Z maintains this Plan as a separate and distinct plan
for the exclusive benefit of its employees. If Item Z(1)(a)(ii) of the Adoption
Agreement - Plus is selected, each Adopting Employer identified in Item
Z(1)(a)(ii) maintains this Plan as a separate and distinct plan for the
exclusive benefit of its employees. An Adopting Employer's adoption of the Plan
shall be in writing. If the Adopting Employer did not maintain a Prior Plan, the
date of adoption specified in Item Z is the Effective Date of its Plan. This
date is the first Yearly Date for the Adopting Employer's Plan and shall be the
Entry Date for any of its employees who have met the requirements in Section
2.01 as of that date. If the Adopting Employer did maintain a Prior Plan, the
date of adoption is the Restatement Date of its Plan.

An Adopting Employer shall be deemed to be the Employer but only with respect to
its Plan and for those Employees who are on its payroll. In interpreting the
Adoption Agreement and this document as to an Adopting Employer, the terms
Employer, we, us, and ours shall be deemed to refer to the Adopting Employer and
the Adopting Employer's fiscal year is deemed to be the Fiscal Year. The primary
Employer in Item B is deemed to be an Adopting Employer for purposes of the
following two paragraphs.

The Contributions made by an Adopting Employer, and Forfeitures arising from
such Contributions, shall not be used to fund the benefits for Employees of any
other Adopting Employer. Service with an Adopting Employer shall be included as
service with all other Adopting Employers and transfer of employment, without
interruption, between Adopting Employers shall not be an interruption of
service. If an Active Member ceases to be an Employee of an Adopting Employer on
other than the last day of the Plan Year and immediately becomes an Employee of
another Adopting Employer, he shall be an Active Member under the first Adopting
Employer's Plan until the next annual Contribution, if any, is due, regardless
of whether he has also become an Active Member in the other Adopting Employer's
Plan. Both Adopting Employers' Contributions on his behalf will be
proportionately reduced on that date based upon his period of employment with
and Pay from each.

If an integrated allocation formula is in effect and a Member received Pay from
more than one Adopting Employer during a Pay Year, the Integration Level used to
determine the allocation of an Adopting Employer's Contributions is equal to his
Integration Level multiplied by the ratio of (a) the Member's Pay from the
Adopting Employer for that year to (b) the Member's Pay from all Adopting
Employers for that year.

Any amendment to the Plan by the primary Employer in Item B of the Adoption
Agreement shall be deemed to be an amendment to each Adopting Employer's Plan.
Without the consent of any other Adopting Employer, an Adopting Employer may
restate its Plan in the form of a separate document at any time and, in that
event, cease to be an Adopting Employer. An employer shall not be an Adopting
Employer if it ceases to be controlled by us or affiliated with us. Such an
employer may continue its Plan by restating it in the form of a separate
document. This Plan shall be amended to delete a former Adopting Employer from
Item Z of the Adoption Agreement.

<PAGE>   24
If the Plan of the Adopting Employer terminates, the provisions of Article VII
shall apply to its Plan.

SECTION 2.04  -  ADOPTING EMPLOYERS  -  SINGLE PLAN.

If the Adoption Agreement - Plus is not used, each Adopting Employer listed in
Item Y and each Controlled Group member, whether or not listed in that item,
shall be an Adopting Employer who participates with us in this Plan. If Item
Z(1)(b)(i) of the Adoption Agreement - Plus is selected, each Adopting Employer
listed in Item Z participates with us in this Plan. If Item Z(1)(b)(ii) of the
Adoption Agreement - Plus is selected, each Adopting Employer identified in Item
Z(1)(b)(ii) participates with us in this Plan. An Adopting Employer's agreement
to participate in this Plan shall be in writing. Employees of Adopting Employers
who do not make such written agreement shall be eligible to become Members and
shall be entitled to Contributions in the same manner as if their employers had
agreed to participate in the Plan. An Adopting Employer has no rights or
privileges under this Plan.

If the Adopting Employer did not maintain a Prior Plan, the date of
participation in Item Z (Item Y) shall be the Entry Date for any of its
employees who have met the requirements in Section 2.01 as of that date. Service
with and pay from an Adopting Employer shall be included as service with and pay
from us. Transfer of employment, without interruption, between an Adopting
Employer and another Adopting Employer or us shall not be considered an
interruption of service. Our Fiscal Year in Item F shall be the Fiscal Year used
in interpreting this Plan for Adopting Employers.

Contributions made by an Adopting Employer shall be treated as Contributions
made by us. Forfeitures arising from those Contributions shall be used for the
benefit of all Members.

An employer shall not be an Adopting Employer if it ceases to be controlled by
us or affiliated with us. Such an employer may continue a retirement plan for
its employees in the form of a separate document. This Plan shall be amended to
delete a former Adopting Employer from the list of Adopting Employers in the
Adoption Agreement.

If an employer ceases to be an Adopting Employer and does not continue a
retirement plan for the benefit of its employees, partial termination may result
and the provisions of Article VII apply.

CONTRIBUTIONS


SECTION 3.01  -  EMPLOYER CONTRIBUTIONS.

Our Contributions are conditioned on initial qualification of the Plan. If the
Plan is denied initial qualification, the provisions of Section 9.15 shall
apply.

The amount of our Contributions is specified in the Adoption Agreement. Our
Contributions are made from Net Profits unless otherwise specified in Item Q.
Notwithstanding the foregoing, the Plan shall continue to be designed to qualify
as a profit sharing plan for purposes of Code Sections 401(a), 402, 412, and
417.

No Member shall be permitted to have Elective Deferral Contributions, as defined
in Section 3.07, made under this Plan, or any other qualified plan maintained by
us, during any taxable year, in excess of the dollar limitation contained in
Code Section 402(g) in effect at the beginning of such taxable year.

If Matching Contributions, Additional Contributions or Qualified Nonelective
Contributions under Item P(l)(a) of the Adoption Agreement - Plus are made from
Net Profits, Item Q, and our Net Profits are not sufficient to provide such
Contributions, such Contributions shall be proportionately reduced.

Our Contributions are allocated according to the provisions of Section 3.05.

If Item Q(2)(a) is selected, we may make all or part of our annual Contributions
before the end of the Plan Year. Such Contributions shall be allocated when made
in a manner which approximates the allocation which would otherwise have been
made as of the last day of the Plan Year. Succeeding allocations shall take into
account amounts previously allocated for the Plan Year. The percentage of our
Contributions allocated to the Member for the Plan Year shall be the same
percentage which would have been allocated to him if the entire allocation had
been made as of the last day of the Plan Year.

We shall pay to the Insurer or Trustee our Contributions used to determine the
Actual Deferral Percentage, as defined in Section 3.07, (Elective Deferral
Contributions, Qualified Nonelective Contributions, and Qualified Matching
Contributions) to the Plan for each Plan Year not later than the end of the
twelve-month period immediately following the Plan Year for which they are
deemed to be paid. Any such Contributions accumulated through payroll deductions
shall be paid within 90 days of the date withheld or the date it is first
reasonably practical for us to do so, if earlier.

A portion of the Plan assets resulting from our Contributions (but not more than
the original amount of those Contributions) may be returned if our Contributions
are made because of a mistake of fact or are more than the amount deductible
under Code Section 404 (excluding any amount which is not deductible because the
Plan is disqualified). The amount involved must be


ARTICLE III                           -25-
<PAGE>   26
returned to us within one year after the date our Contributions are made by
mistake of fact or the date the deduction is disallowed, whichever applies.
Except as provided under this paragraph and Articles VII and IX, the assets of
the Plan shall never be used for our benefit and are held for the exclusive
purpose of providing benefits to Members and their Beneficiaries and for
defraying reasonable expenses of administering the Plan.

Prior Plan Assets which result from contributions made by us shall be treated in
the same manner as Employer Contributions made under this Plan. They shall be
treated in the same manner as Employer Contributions made under this Plan before
a Forfeiture Date if the Prior Plan Assets are transferred from a terminated
plan.

SECTION 3.02  -  VOLUNTARY CONTRIBUTIONS BY MEMBERS.

If permitted under Item S, an Active Member may make Voluntary Contributions.
Voluntary Contributions shall be made according to nondiscriminatory procedures
and limitations set up by the Plan Administrator.

A Member's membership in the Plan is not affected by stopping or changing
Voluntary Contributions. An Active Member's request to start, change, or stop
Voluntary Contributions must be in writing on a form furnished for that purpose.
The form must be delivered to the Plan Administrator before the date the Member
is to start, change, or stop Voluntary Contributions.

The part of the Member's Account resulting from Voluntary Contributions is fully
(100%) vested and nonforfeitable at all times.

Prior Plan Assets which result from voluntary contributions made by the Member
shall be treated in the same manner as Voluntary Contributions made under this
Plan. These Prior Plan Assets may include deductible Voluntary Contributions
which were made according to the provisions of the Prior Plan.

SECTION 3.03  -  ROLLOVER CONTRIBUTIONS.

With our consent, a Rollover Contribution may be made by or for an Eligible
Employee if the following conditions are met:

(a)      The Contribution is a rollover contribution which the Code permits to
         be transferred to a plan that meets the requirements of Code Section
         401(a).

(b)      If the Contribution is made by the Eligible Employee, it is made within
         sixty days after he receives the distribution.

(c)      The Eligible Employee furnishes evidence satisfactory to the Plan
         Administrator that the proposed transfer is in fact a rollover
         contribution which meets conditions (a) and (b) above.


ARTICLE III                           -26-
<PAGE>   27
The Rollover Contribution may be made by the Eligible Employee or the Eligible
Employee may direct the trustee or named fiduciary of another plan to transfer
the funds which would otherwise be a Rollover Contribution directly to this
Plan. Such transferred funds shall be called a Rollover Contribution. The
Contribution shall be made according to procedures set up by the Plan
Administrator.

If an Eligible Employee participated in a retirement plan which met the
requirements of Code Section 401(a), with our consent, the trustee or named
fiduciary of that plan may transfer funds which could not have been a Rollover
Contribution to this Plan on behalf of the Eligible Employee. The transferred
funds shall be called a Rollover Contribution. If such Rollover Contributions
were made for a period when the Eligible Employee was a five-percent owner of
the employer that maintained the plan, the Rollover Contributions shall be
treated in the same manner as if they were Contributions made under this Plan
for a period when he was a five-percent owner of us.

If the Eligible Employee is not an Active Member when the Rollover Contribution
is made, he shall be deemed to be an Active Member only for the purpose of
investment and distribution of the Rollover Contribution. Our Contributions
shall not be made for or allocated to the Eligible Employee and he may not make
Member Contributions, until the time he meets all of the requirements to become
an Active Member.

Rollover Contributions made by or for an Eligible Employee shall be credited to
his Account. The part of the Member's Account resulting from Rollover
Contributions is fully (100%) vested and nonforfeitable at all times. A separate
accounting record shall be maintained for that part of his Rollover Contribution
consisting of voluntary contributions which were deducted from the Member's
gross income for Federal income tax purposes.

Prior Plan Assets which result from the Member's rollover contributions shall be
treated in the same manner as Rollover Contributions made under this Plan.

SECTION 3.04  -  FORFEITURES AND RESTORATION.

The Nonvested Account of a Member shall be forfeited as of the earlier of the
following: the date the Member dies, if prior to such date he had ceased to be
an Employee; or his Forfeiture Date. All or part of a Member's Nonvested Account
will be forfeited if, after he ceases to be an Employee, he receives a
distribution of his entire Vested Account or a distribution of his Vested
Account derived from our Contributions which were not 100% vested when made
according to the provisions of Section 5.03 or Section 9.11. If a Member's
Vested Account is zero on the date he ceases to be an Employee, he shall be
deemed to have received a distribution of his entire Vested Account on such
date. The forfeiture will occur as of the date he receives the distribution or
on the date such provision became effective, if later. If he receives a
distribution of his entire Vested Account, his entire Nonvested Account will be
forfeited. If he receives a distribution of his Vested Account from our
Contributions which were not 100% vested when made, but less than his entire
Vested Account, the amount to be forfeited will be determined by multiplying his
Nonvested Account by a fraction. The numerator of the fraction is the amount of
the distribution derived from our Contributions which were not 100% vested when
made and the denominator of


ARTICLE III                           -27-
<PAGE>   28
the fraction is his entire Vested Account derived from such Contributions on the
date of the distribution.

If the Adoption Agreement - Plus is used, Forfeitures shall be allocated as of
the last day of the Plan Year in which such Forfeitures arise or applied to
reduce the earliest Employer Contribution made after the Forfeitures are
determined as provided in Item P(4). Forfeitures shall be determined at least
once during each taxable year of ours. If the Adoption Agreement - Plus is not
used and Item P(2) is selected, Forfeitures shall be allocated with our
Discretionary Contributions and deemed to be Discretionary Contributions as of
the last day of the Plan Year in which such Forfeitures arise. If the Adoption
Agreement - Plus is not used and Item P(2) is not selected, Forfeitures shall be
applied to reduce the earliest Employer Contribution made after the Forfeitures
are determined. Forfeitures of Matching Contributions which relate to excess
amounts shall be applied as provided in Section 3.07.

Forfeitures may first be applied to pay expenses under the Plan which would
otherwise be paid by us before they are applied or allocated as provided above.
Upon their application or allocation, such Forfeitures shall be deemed to be
Employer Contributions.

If a Member again becomes an Eligible Employee after receiving a distribution
which caused his Nonvested Account to be forfeited, he shall have the right to
repay to the Plan the entire amount of the distribution he received (excluding
any amount of such distribution resulting from Contributions which were 100%
vested when made). The repayment must be made before the earlier of the date
five years after the date he again becomes an Eligible Employee or the end of
the first period of five consecutive Vesting Breaks which begin after the date
of the distribution.

If the Member makes the repayment provided above, the Plan Administrator shall
restore to his Account an amount equal to his Nonvested Account which was
forfeited on the date of distribution, unadjusted for any investment gains or
losses. If the Member was deemed to have received a distribution because his
Vested Account was zero or the Plan did not have the repayment provisions in
effect on the date the distribution was made and he again performs an Hour of
Service as an Eligible Employee within the repayment period, the Plan
Administrator shall restore the Member's Account as if he had made a required
repayment on the date he performed such Hour of Service. Restoration of the
Member's Account shall include restoration of all Code Section 411(d)(6)
protected benefits with respect to the restored Account, according to applicable
Treasury regulations. Provided, however, the Plan Administrator shall not
restore the Nonvested Account if a Forfeiture Date has occurred after the date
of the distribution and on or before the date of repayment and that Forfeiture
would result in a complete forfeiture of the amount the Plan Administrator would
otherwise restore.

The Plan Administrator shall restore the Member's Account by the close of the
Plan Year following the Plan Year in which repayment is made.

SECTION 3.05 - ALLOCATION.

Our Contributions which are not subject to the requirements of Item Q(2) shall
be allocated to the Members for whom they were made and credited to the Members'
Accounts. Our


ARTICLE III                          -28-
<PAGE>   29
Contributions which are subject to the requirements of Item Q(2) plus any
Forfeitures released for allocation for the Plan Year, shall be allocated among
all persons meeting the requirements in Items P and Q. The amount allocated to
such a person shall be determined under the allocation formula selected in the
Adoption Agreement and Article X.

In determining the amount of our Contributions allocated to a Member who is a
Leased Employee, contributions and benefits provided by the leasing organization
which are attributable to services such Leased Employee performs for us shall be
treated as provided by us. Those contributions or benefits shall not be
duplicated under this Plan.

SECTION 3.06  -  CONTRIBUTION LIMITATION.

(a)      For the purpose of determining the contribution limitation set forth in
         this section, the following terms are defined:

         ANNUAL ADDITIONS mean the sum of the following amounts credited to a
         Member's account for the Limitation Year:

         (1)      employer contributions,

         (2)      employee contributions,

         (3)      forfeitures, and

         (4)      amounts allocated, after March 31, 1984, to an individual
                  medical account, as defined in Code Section 415(l)(2), which
                  is part of a pension or annuity plan maintained by the
                  Employer.

         These amounts are treated as Annual Additions to a defined contribution
         plan. Also amounts derived from contributions paid or accrued after
         December 31, 1985, in taxable years ending after such date, which are
         attributable to post-retirement medical benefits, allocated to the
         separate account of a key employee, as defined in Code Section
         419A(d)(3), under a welfare benefit fund, as defined in Code Section
         419(e), maintained by the Employer are treated as Annual Additions to a
         defined contribution plan.

         For this purpose, any Excess Amount applied under (d) and (j) below in
         the Limitation Year to reduce Employer Contributions will be considered
         Annual Additions for such Limitation Year.

         COMPENSATION means a Member's earned income, wages, salaries, fees for
         professional service, and other amounts received for personal service
         actually rendered in the course of employment with the employer
         maintaining the plan. Compensation includes, but is not limited to,
         commissions for salesmen, compensation for services on the basis of a
         percentage of profits, commissions on insurance premiums, tips, and
         bonuses. Compensation excludes the following:


ARTICLE III                           -29-
<PAGE>   30
         (1)      Employer contributions to a plan of deferred compensation to
                  the extent contributions are not included in the gross income
                  of the Employee for the taxable year in which contributed, or
                  employer contributions under a simplified employee pension
                  plan to the extent such contributions are deductible by the
                  Employee, or any distributions from a plan of deferred
                  compensation.

         (2)      Amounts realized from the exercise of a non-qualified stock
                  option, or when restricted stock (or property) held by an
                  Employee becomes freely transferable or is no longer subject
                  to a substantial risk of forfeiture.

         (3)      Amounts realized from the sale, exchange or other disposition
                  of stock acquired under a qualified stock option.

         (4)      Other amounts which receive special tax benefits, or
                  contributions made by the employer (whether or not under a
                  salary reduction agreement) towards the purchase of an annuity
                  described in Code Section 403(b) (whether or not the amounts
                  are actually excludible from the gross income of the
                  Employee).

         For purposes of applying the limitations of this section, Compensation
         for a Limitation Year is the Compensation actually paid or made
         available to the Member within the Limitation Year (accrued for the
         Member within the Limitation Year, if so elected in the Adoption
         Agreement - Plus).

         For any Limitation Year beginning after December 31, 1988, only the
         first $200,000 (multiplied by the Adjustment Factor) of the Member's
         Compensation shall be taken into account under the Plan.

         DEFINED BENEFIT PLAN FRACTION means a fraction, the numerator of which
         is the sum of the Member's Projected Annual Benefits under all the
         defined benefit plans (whether or not terminated) maintained by the
         Employer, and the denominator of which is the lesser of 125 percent of
         the dollar limitation determined for the Limitation Year under Code
         Sections 415 (b) and (d) or 140 percent of the Highest Average
         Compensation, including any adjustments under Code Section 415(b).

         Notwithstanding the above, if the Member was a member as of the first
         day of the first Limitation Year beginning after December 31, 1986, in
         one or more defined benefit plans maintained by the Employer which were
         in existence on May 6, 1986, the denominator of this fraction will not
         be less than 125 percent of the sum of the annual benefits under such
         plans which the Member had accrued as of the close of the last
         Limitation Year beginning before January 1, 1987, disregarding any
         changes in the terms and conditions of the plan after May 5, 1986. The
         preceding sentence applies only if the defined benefit plans
         individually and in the aggregate satisfied the requirements of Code
         Section 415 for all Limitation Years beginning before January 1, 1987.


ARTICLE III                           -30-
<PAGE>   31
         DEFINED CONTRIBUTION DOLLAR LIMITATION means $30,000 or if greater,
         one-fourth of the defined benefit dollar limitation set forth in Code
         Section 415(b)(1) as in effect for the Limitation Year.

         DEFINED CONTRIBUTION PLAN FRACTION means a fraction, the numerator of
         which is the sum of the Annual Additions to the Member's account under
         all the defined contribution plans (whether or not terminated)
         maintained by the Employer for the current and all prior Limitation
         Years (including the Annual Additions attributable to the Member's
         nondeductible employee contributions to all defined benefit plans,
         whether or not terminated, maintained by the Employer, and the Annual
         Additions attributable to all welfare benefit funds, as defined in Code
         Section 419(e), and individual medical accounts, as defined in Code
         Section 415(l)(2), maintained by the Employer), and the denominator of
         which is the sum of the maximum aggregate amounts for the current and
         all prior Limitation Years of service with the Employer (regardless of
         whether a defined contribution plan was maintained by the Employer).
         The maximum aggregate amount in any Limitation Year is the lesser of
         125 percent of the dollar limitation determined under Code Section
         415(b) and (d) in effect under Code Section 415(c)(1)(A) of the Code or
         35 percent of the Member's Compensation for such year.

         If the Member was a member as of the end of the first Limitation Year
         beginning after December 31, 1986, in one or more defined contribution
         plans maintained by the Employer which were in existence on May 6,
         1986, the numerator of this fraction shall be adjusted if the sum of
         this fraction and the Defined Benefit Plan Fraction would otherwise
         exceed 1.0 under the terms of this Plan. Under the adjustment, an
         amount equal to the product of (1) the excess of the sum of the
         fractions over 1.0 times (2) the denominator of this fraction, will be
         permanently subtracted from the numerator of this fraction. The
         adjustment is calculated using the fractions as they would be computed
         as of the end of the last Limitation Year beginning before January 1,
         1987, and disregarding any changes in the terms and conditions of the
         plan made after May 5, 1986, but using the Code Section 415 limitations
         applicable to the first Limitation Year beginning on or after January
         1, 1987.

         The Annual Addition for any Limitation Year beginning before January 1,
         1987, shall not be recomputed to treat all employee contributions as
         Annual Additions.

         EMPLOYER means the employer that adopts this Plan and all members of a
         controlled group of corporations (as defined in Code Section 414(b) as
         modified by Code Section 415(h)), all commonly controlled trades or
         businesses (as defined in Code Section 414(c) as modified by Code
         Section 415(h)) or affiliated service groups (as defined in Code
         Section 414(m)) of which the adopting employer is a part, and any other
         entity required to be aggregated with the employer pursuant to
         regulations under Code Section 414(o).

         EXCESS AMOUNT means the excess or the Member's Annual Additions for the
         Limitation Year over the Maximum Permissible Amount.


ARTICLE III                           -31-
<PAGE>   32
         Highest Average Compensation means the average Compensation for the
         three consecutive Years of Service (see Section 1.02) with the Employer
         that produces the highest average.

         LIMITATION YEAR means a calendar year or the 12-consecutive month
         period elected by the Employer in Item R. If the Limitation Year ends
         on the last day of the Fiscal Year and the Fiscal Year is a 52-53 week
         period, then the Limitation Year shall be such period. All qualified
         plans maintained by the Employer must use the same Limitation Year. If
         the Limitation Year is amended to a different 12-consecutive month
         period, the new Limitation Year must begin on a date within the
         Limitation Year in which the amendment is made.

         MASTER OR PROTOTYPE PLAN means a plan the form of which is the subject
         of a favorable opinion letter from the Internal Revenue Service.

         MAXIMUM PERMISSIBLE AMOUNT means the maximum Annual Addition that may
         be contributed or allocated to a Member's Account under the Plan for
         any Limitation Year. This amount shall not exceed the lesser of:

         (1)      the Defined Contribution Dollar Limitation, or

         (2)      25 percent of the Member's Compensation for the Limitation
                  Year.

         The compensation limitation referred to in (2) shall not apply to any
         contribution for medical benefits (within the meaning of Code Section
         401(h) or Code Section 419A(f)(2)) which is otherwise treated as an
         Annual Addition under Code Section 415(l)(1) or 419A(d)(2).

         If a short Limitation Year is created because of an amendment changing
         the Limitation Year to a different 12-consecutive month period, the
         Maximum Permissible Amount will not exceed the Defined Contribution
         Dollar Limitation multiplied by the following fraction:

                  Number of months in the short Limitation Year
                  ---------------------------------------------
                                       12

         PROJECTED ANNUAL BENEFIT means the annual retirement benefit (adjusted
         to an actuarially equivalent straight life annuity if such benefit is
         expressed in a form other than a straight life annuity or qualified
         joint and survivor form) to which the Member would be entitled under
         the terms of the plan assuming:

         (1)      the Member will continue employment until normal retirement
                  age under the plan (or current age, if later), and

         (2)      the Member's Compensation for the current Limitation Year and
                  all other relevant factor used to determine benefits under the
                  plan will remain constant for all future Limitation Years.

(b)      If the Member does not participate in, and has never participated in
         another qualified plan maintained by the Employer or a welfare benefit
         fund, as defined in Code Section 419(e) maintained by the Employer, or
         an individual medical account, as defined in Code Section 415(l)(2) of
         the Code, maintained by the Employer, which provides an Annual
         Addition, the amount of Annual Additions which may be credited to the
         Member's Account for any Limitation Year will not exceed the lesser of
         the Maximum Permissible amount or any other limitation contained in
         this Plan. If the Employer Contribution that would otherwise be
         contributed or allocated to the Member's Account would cause the Annual
         Additions for the Limitation Year to exceed the Maximum Permissible
         Amount, the amount contributed or allocated will be reduced so that the
         Annual Additions for the Limitation Year will equal the Maximum
         Permissible Amount.

(c)      Prior to determining the Member's actual Compensation for the
         Limitation Year, the Employer may determine the Maximum Permissible
         Amount for a Member on the basis of reasonable estimation of the
         Member's Compensation for the Limitation Year, uniformly determined for
         all Members similarly situated.

(d)      As soon as is administratively feasible after the end of the Limitation
         Year, the Maximum Permissible Amount for the Limitation Year will be
         determined on the basis of the Member's actual Compensation for the
         Limitation Year.

(e)      If pursuant to (d) above or as a result of the allocation of
         forfeitures, there is an Excess Amount, the excess will be disposed of
         as follows:

         (1)      Any nondeductible voluntary employee contributions, to the
                  extent they would reduce the excess amount, will be returned
                  to the Member;

         (2)      If after the application of (1) above an Excess Amount still
                  exists, and the Member is covered by the Plan at the end of
                  the Limitation Year, the Excess Amount in the Member's Account
                  will be used to reduce Employer Contributions (including any
                  allocation of forfeitures) for such Member in the next
                  Limitation Year, and each succeeding Limitation Year if
                  necessary.

         (3)      If after the application of (1) above an excess amount still
                  exists, and the Member is not covered by the Plan at the end
                  of a Limitation Year, the Excess Amount will be held
                  unallocated in a suspense account. The suspense account will
                  be applied to reduce future Employer Contributions for all
                  remaining Members in the next Limitation Year, and each
                  succeeding Limitation Year if necessary.

         (4)      If a suspense account is in existence at any time during a
                  Limitation Year pursuant to this (d), it will not participate
                  in the allocation of the trust's investment gains or losses.
                  If a suspense account is in existence at any time during a


ARTICLE III                           -33-
<PAGE>   34
                  particular Limitation Year, all amounts in the suspense
                  account must be allocated and reallocated to Member's Accounts
                  before any Employer or any Member contributions may be made to
                  the Plan for that Limitation Year. Excess amounts may not be
                  distributed to Members or former Members.

(e)      This (e) applies if, in addition to this Plan, the Member is covered
         under another qualified defined contribution Master or Prototype Plan
         maintained by the Employer, a welfare benefit fund, as defined in Code
         Section 419(e), maintained by the Employer, or an individual medical
         account, as defined in Code Section 415(l)(2), maintained by the
         Employer, which provides an Annual Addition, during any Limitation
         Year. The Annual Additions which may be credited to a Member's Account
         under this Plan for any such Limitation Year will not exceed the
         Maximum Permissible Amount reduced by the Annual Additions credited to
         a Member's account under the other plans and welfare benefit funds for
         the same Limitation Year. If the Annual Additions with respect to the
         Member under other defined contribution plans and welfare benefit funds
         maintained by the Employer are less than the Maximum Permissible Amount
         and the Employer Contribution that would otherwise be contributed or
         allocated to the Member's Account under this Plan would cause the
         Annual Additions for the Limitation Year to exceed this limitation, the
         amount contributed or allocated will be reduced so that the Annual
         Additions under all such plans and funds for the Limitation Year will
         equal the Maximum Permissible Amount. If the Annual Additions with
         respect to the Member under such other defined contribution plans and
         welfare benefit funds in the aggregate are equal to or greater than the
         Maximum Permissible Amount, no amount will be contributed or allocated
         to the Member's Account under this Plan for the Limitation Year.

(f)      Prior to determining the Member's actual Compensation for the
         Limitation Year, the Employer may determine the Maximum Permissible
         Amount for a Member in the manner described in (b) above.

(g)      As soon as is administratively feasible after the end of the Limitation
         Year, the Maximum Permissible Amount for the Limitation Year will be
         determined on the basis of the Member's actual Compensation for the
         Limitation Year.

(h)      If pursuant to (g) above or as a result of the allocation of
         forfeitures, a Member's Annual Additions under this Plan and such other
         plans would result in an Excess Amount for a Limitation Year, the
         Excess Amount will be deemed to consist of the Annual Additions last
         allocated, except that Annual Additions attributable to a welfare
         benefit fund or individual medical account will be deemed to have been
         allocated first regardless of the actual allocation date.

(i)      If an Excess Amount was allocated to a Member on an allocation date of
         this Plan which coincides with an allocation date of another plan, the
         Excess Amount attributed to this Plan will be the product of,

         (1)      the total Excess Amount allocated as of such date, times


ARTICLE III                           -34-
<PAGE>   35
         (2)      the ratio of (i) the Annual Additions allocated to the Member
                  for the Limitation Year as of such date under this Plan to
                  (ii) the total Annual Additions allocated to the Member for
                  the Limitation Year as of such date under this and all the
                  other qualified defined contribution Master and Prototype
                  Plans.

(j)      Any excess amount attributed to this Plan will be disposed in the
         manner described in (d) above.

(k)     If the Member is covered under another qualified defined contribution
        plan maintained by the Employer which is not a Master or Prototype Plan,
        Annual Additions which may be credited to the Member's Account under
        this Plan for any Limitation Year will be limited in accordance with (e)
        through (j) above as though the other plan were a Master or Prototype
        Plan unless the Employer provides other limitations in Item R.

(l)     If the Employer maintains, or at any time maintained, a qualified
        defined benefit plan covering any Member in this Plan, the sum of the
        Member's Defined Benefit Plan Fraction and Defined Contribution Plan
        Fraction will not exceed 1.0 in any Limitation Year. The Annual
        Additions credited to the Member's Account under this Plan for any
        Limitation Year will be limited in accordance with Item R.

SECTION 3.07  -  EXCESS AMOUNTS.

         (a)      For the purposes of this section, the following terms are
                  defined:

                  ACTUAL DEFERRAL PERCENTAGE means the ratio (expressed as a
                  percentage) of Elective Deferral Contributions under this Plan
                  on behalf of the Eligible Member for the Plan Year to the
                  Eligible Member's Pay for the Plan Year (whether or not the
                  Eligible Member was a Member for the entire Plan Year). For
                  the first Plan Year of the cash or deferred arrangement, the
                  amount of Pay for the entire 12-month period ending on the
                  last day of such Plan Year shall be taken into account. If
                  selected in Item M, for Plan Years beginning before January 1,
                  1992, or such later date as provided in Internal Revenue
                  Service regulations, and in modification of the foregoing, Pay
                  shall be limited to the Pay received while an Active Member of
                  the Plan. The Elective Deferral Contributions used to
                  determine the Actual Deferral Percentage shall include Excess
                  Elective Deferrals, but shall exclude Elective Deferral
                  Contributions that are used in computing the Contribution
                  Percentage (provided the Average Actual Deferral Percentage
                  test is satisfied both with and without exclusion of these
                  Elective Deferral Contributions). Under such rules as the
                  Secretary of the Treasury shall prescribe, we may elect to
                  include Qualified Nonelective Contributions and Qualified
                  Matching Contributions under this Plan in computing the Actual
                  Deferral Percentage. For an Eligible Member for whom such
                  Contributions on his behalf for the Plan Year are zero, the
                  percentage is zero.

                  AGGREGATE LIMIT means the sum of


ARTICLE III                           -35-
<PAGE>   36
                  (1)      125 percent of the greater of the Average Actual
                           Deferral Percentage of the Nonhighly Compensated
                           Employees for the Plan Year or the Average
                           Contribution Percentage of Nonhighly Compensated
                           Employees under the Plan subject to Code Section
                           401(m) for the Plan Year beginning with or within the
                           Plan Year of the cash or deferred arrangement and

                  (2)      the lesser of 200% or two plus the lesser of such
                           Average Actual Deferral Percentage or Average
                           Contribution Percentage.

                  AVERAGE ACTUAL DEFERRAL PERCENTAGE means the average
                  (expressed as a percentage) of the Actual Deferral Percentages
                  of the Eligible Members in a group.

                  AVERAGE CONTRIBUTION PERCENTAGE means the average (expressed
                  as a percentage) of the Contribution Percentages of the
                  Eligible Members in a group.

                  CONTRIBUTION PERCENTAGE means the ratio (expressed as a
                  percentage) of the Eligible Member's Contribution Percentage
                  Amounts to the Eligible Member's Pay for the Plan Year
                  (whether or not the Eligible Member was a Member for the
                  entire Plan Year). For the first Plan Year of the Plan, the
                  amount of Pay for the entire 12-month period ending on the
                  last day of such Plan Year shall be taken into account. If
                  selected in Item M, for Plan Years beginning before January 1,
                  1992, or such later date as provided in Internal Revenue
                  Service regulations, and in modification of the foregoing, Pay
                  shall be limited to the Pay received while an Active Member of
                  the Plan. For an Eligible Member for whom such Contribution
                  Percentage Amounts for the Plan Year are zero, the percentage
                  is zero.

                  CONTRIBUTION PERCENTAGE AMOUNTS means the sum of the Member
                  Contributions and Matching Contributions (that are not
                  Qualified Matching Contributions) under this Plan on behalf of
                  the Eligible Member for the Plan Year. Under such rules as the
                  Secretary of the Treasury shall prescribe, we may elect to
                  include Qualified Nonelective Contributions and Qualified
                  Matching Contributions under this Plan which were not used in
                  computing the Actual Deferral Percentage in computing the
                  Contribution Percentage. We may also elect to use Elective
                  Deferral Contributions in computing the Contribution
                  Percentage so long as the Average Actual Deferral Percentage
                  test is met before the Elective Deferral Contributions are
                  used in the Average Contribution Percentage test and continues
                  to be met following the exclusion of those Elective Deferral
                  Contributions that are used to meet the Average Contribution
                  Percentage test.

                  ELECTIVE DEFERRAL CONTRIBUTIONS means employer contributions
                  made on behalf of a member pursuant to an election to defer
                  under any qualified cash or deferred arrangement as described
                  in Code Section 401(k), any simplified employee pension cash
                  or deferred arrangement as described in Code Section
                  402(h)(1)(B), any eligible deferred compensation plan under
                  Code Section 457, any plan as described under Code Section
                  501(c)(18), and any employer contributions made


ARTICLE III                           -36-
<PAGE>   37
                  on behalf of a member for the purchase of an annuity contract
                  under Code Section 403(b) pursuant to a salary reduction
                  agreement.

                  ELIGIBLE MEMBER means, for purposes of determining the Actual
                  Deferral Percentage, any Employee who is otherwise authorized
                  under the terms of the Plan to have Elective Deferral
                  Contributions made on his behalf for the Plan Year. Eligible
                  Member means, for purposes of determining the Average
                  Contribution Percentage, any Employee who is otherwise
                  authorized under the terms of the Plan to have Member
                  Contributions or Matching Contributions made on his behalf for
                  the Plan Year.

                  EXCESS AGGREGATE CONTRIBUTIONS means, with respect to any Plan
                  Year, the excess of:

                  (1)      The aggregate Contributions taken into account in
                           computing the numerator of the Contribution
                           Percentage actually made on behalf of Highly
                           Compensated Employees for such Plan Year, over

                  (2)      The maximum amount of such Contributions permitted by
                           the Average Contribution Percentage test (determined
                           by reducing Contributions made on behalf of Highly
                           Compensated Employees in order of their Contribution
                           Percentages beginning with the highest of such
                           percentages).

                  Such determination shall be made after first determining
                  Excess Elective Deferrals and then determining Excess
                  Contributions.

                  EXCESS CONTRIBUTIONS means, with respect to any Plan Year, the
                  excess of:

                  (1)      The aggregate amount of Contributions actually taken
                           into account in computing the Actual Deferral
                           Percentage of Highly Compensated Employees for such
                           Plan Year, over

                  (2)      The maximum amount of such Contributions permitted by
                           the Actual Deferral Percentage test (determined by
                           reducing Contributions made on behalf of Highly
                           Compensated Employees in order of the Actual Deferral
                           Percentages, beginning with the highest of such
                           percentages).

                  Such determination shall be made after first determining
                  Excess Elective Deferrals.

                  EXCESS ELECTIVE DEFERRALS means those Elective Deferral
                  Contributions that are includible in a Member's gross income
                  under Code Section 402(g) to the extent such Member's Elective
                  Deferral Contributions for a taxable year exceed the dollar
                  limitation under such Code section. Excess Elective Deferrals
                  shall be treated as Annual Additions under the Plan.


ARTICLE III                           -37-
<PAGE>   38
                  MATCHING CONTRIBUTIONS means employer contributions made to
                  this or any other defined contribution plan, or to a contract
                  described in Code Section 403(b), on behalf of a member on
                  account of a Member Contribution made by such member, or on
                  account of a member's Elective Deferral Contributions, under a
                  plan maintained by the employer.

                  MEMBER CONTRIBUTIONS means contributions made to any plan by
                  or on behalf of a member that are included in the member's
                  gross income in the year in which made and that are maintained
                  under a separate account to which earnings and losses are
                  allocated.

                  QUALIFIED MATCHING CONTRIBUTIONS means Matching Contributions
                  which are subject to the distribution and nonforfeitability
                  requirements under Code Section 401(k) when made.

                  QUALIFIED NONELECTIVE CONTRIBUTIONS means any employer
                  contributions (other than Matching Contributions) which an
                  employee may not elect to have paid to him in cash instead of
                  being contributed to the plan and which are subject to the
                  distribution and nonforfeitability requirements under Code
                  Section 401(k).

         (b)      A Member may assign to this Plan any Excess Elective Deferrals
                  made during a taxable year of the Member by notifying the Plan
                  Administrator in writing on or before the first following
                  March 1 of the amount of the Excess Elective Deferrals to be
                  assigned to the Plan. The Member's claim for Excess Elective
                  Deferrals shall be accompanied by the Member's written
                  statement that if such amounts are not distributed, such
                  Excess Elective Deferrals, when added to amounts deferred
                  under other plans or arrangements described in Code Sections
                  401(k), 408(k) or 403(b), will exceed the limit imposed on the
                  Member by Code Section 402(g) for the year in which the
                  deferral occurred. The Excess Elective Deferrals assigned to
                  this Plan can not exceed the Elective Deferral Contributions
                  allocated under this Plan for such taxable year.

                  Notwithstanding any other provisions of the Plan, Elective
                  Deferral Contributions in an amount equal to the Excess
                  Elective Deferrals assigned to this Plan, plus any income and
                  minus any loss allocable thereto, shall be distributed no
                  later than April 15 to any Member to whose Account Excess
                  Elective Deferrals were assigned for the preceding year and
                  who claims Excess Elective Deferrals for such taxable year.
                  Elective Deferral Contributions under this Plan which are
                  distributed as Excess Elective Deferrals shall be treated as
                  Annual Additions under the Plan.

                  The income or loss allocable to such Excess Elective Deferrals
                  shall be equal to the sum of:


                                      -38-

                  (1)      the income or loss allocable to the Member's Elective
                           Deferral Contributions for the taxable year in which
                           the excess occurred multiplied by a fraction and

                  (2)      the income or loss allocable to the Member's Elective
                           Deferral Contributions for the gap period between the
                           end of such taxable year and the date of distribution
                           multiplied by a fraction.

                  The numerator of the fractions is the Excess Elective
                  Deferrals. The denominator of the fraction in (1) above is the
                  closing balance without regard to any income or loss occurring
                  during such taxable year (as of the end of such taxable year)
                  of the Member's Account resulting from Elective Deferral
                  Contributions. The denominator of the fraction in (2) above is
                  the closing balance without regard to any income or loss
                  occurring during such gap period (as of the end of such gap
                  period) of the Member's Account resulting from Elective
                  Deferral Contributions.

                  Any Matching Contributions which were based on the Elective
                  Deferral Contributions which are distributed as Excess
                  Elective Deferrals, plus any income and minus any loss
                  allocable thereto, shall be forfeited, if forfeitable. If the
                  Adoption Agreement - Plus is used, these Forfeitures shall be
                  applied according to the provisions of Item O(7). If the
                  Adoption Agreement - Plus is not used, these Forfeitures shall
                  be used to offset the earliest Employer Contribution due after
                  the Forfeiture arises.

         (c)      As of the end of each Plan Year after Excess Elective
                  Deferrals have been determined, one of the following tests
                  must be met:

                  (1)      The Average Actual Deferral Percentage for Eligible
                           Members who are Highly Compensated Employees for the
                           Plan Year is not more than the Average Actual
                           Deferral Percentage for Eligible Members who are
                           Nonhighly Compensated Employees for the Plan Year
                           multiplied by 1.25.

                  (2)      The Average Actual Deferral Percentage for Eligible
                           Members who are Highly Compensated Employees for the
                           Plan Year is not more than the Average Actual
                           Deferral Percentage for Eligible Members who are
                           Nonhighly Compensated Employees for the Plan Year
                           multiplied by 2 and the difference between the
                           Average Actual Deferral Percentages is not more than
                           2.

                  The Actual Deferral Percentage for any Eligible Member who is
                  a Highly Compensated Employee for the Plan Year and who is
                  eligible to have Elective Deferral Contributions (and
                  Qualified Nonelective Contributions or Qualified Matching
                  Contributions, or both, if used in computing the Actual
                  Deferral Percentage) allocated to his account under two or
                  more plans or arrangements described in Code Section 401(k)
                  that are maintained by the us or a Controlled Group member
                  shall be determined as if all such Elective Deferral
                  Contributions

                  (and, if applicable, such Qualified Nonelective Contributions
                  or Qualified Matching Contributions, or both) were made under
                  a single arrangement. If a Highly Compensated Employee
                  participates in two or more cash or deferred arrangements that
                  have different Plan Years, all cash or deferred arrangements
                  ending with or within the same calendar year shall be treated
                  as a single arrangement.

                  In the event that this Plan satisfies the requirements of Code
                  Sections 401(k), 401(a)(4), or 410(b) only if aggregated with
                  one or more other plans, or if one or more other plans satisfy
                  the requirements of such Code sections only if aggregated with
                  this Plan, then this section shall be applied by determining
                  the Actual Deferral Percentage of employees as if all such
                  plans were a single plan. For Plan Years beginning after
                  December 31, 1989, plans may be aggregated in order to satisfy
                  Code Section 401(k) only if they have the same Plan Year.

                  For purposes of determining the Actual Deferral Percentage of
                  an Eligible Member who is a five-percent owner or one of the
                  ten most highly-paid Highly Compensated Employees, the
                  Elective Deferral Contributions (and Qualified Nonelective
                  Contributions or Qualified Matching Contributions, or both, if
                  used in computing the Actual Deferral Percentage) and Pay of
                  such Eligible Member include the Elective Deferral
                  Contributions (and, if applicable, Qualified Nonelective
                  Contributions or Qualified Matching Contributions, or both)
                  and Pay for the Plan Year of Family Members. Family Members,
                  with respect to such Highly Compensated Employees, shall be
                  disregarded as separate employees in determining the Actual
                  Deferral Percentage both for Members who are Nonhighly
                  Compensated Employees and for Members who are Highly
                  Compensated Employees.

                  For purposes of determining the Actual Deferral Percentage,
                  Elective Deferral Contributions, Qualified Nonelective
                  Contributions and Qualified Matching Contributions must be
                  made before the last day of the twelve-month period
                  immediately following the Plan Year to which contributions
                  relate.

                  We shall maintain records sufficient to demonstrate
                  satisfaction of the Average Actual Deferral Percentage test
                  and the amount of Qualified Nonelective Contributions or
                  Qualified Matching Contributions, or both, used in such test.

                  The determination and treatment of the Contributions used in
                  computing the Actual Deferral Percentage shall satisfy such
                  other requirements as may be prescribed by the Secretary of
                  the Treasury.

                  If the Plan Administrator should determine during the Plan
                  Year that neither of the above tests is being met, the Plan
                  Administrator may adjust the amount of future Elective
                  Deferral Contributions of the Highly Compensated Employees.

                  Notwithstanding any other provisions of this Plan, Excess
                  Contributions, plus any income and minus any loss allocable
                  thereto, shall be distributed no later than the last day of
                  each Plan Year to Members to whose Accounts such Excess
                  Contributions were allocated for the preceding Plan Year. If
                  such excess amounts are distributed more than 2 1/2 months
                  after the last day of the Plan Year in which such excess
                  amounts arose, a ten (10) percent excise tax will be imposed
                  on the employer maintaining the plan with respect to such
                  amounts. Such distributions shall be made to Highly
                  Compensated Employees on the basis of the respective portions
                  of the Excess Contributions attributable to each of such
                  employees. Excess Contributions shall be allocated to Members
                  who are subject to the family member aggregation rules of Code
                  Section 414(q)(6) in the manner prescribed by the regulations.

                  Excess Contributions shall be treated as Annual Additions
                  under the Plan.

                  The Excess Contributions shall be adjusted for income or loss.
                  The income or loss allocable to such Excess Contributions
                  shall be equal to the sum of

                  (3)      the income or loss allocable to the Member's Elective
                           Deferral Contributions (and, if applicable, Qualified
                           Nonelective Contributions or Qualified Matching
                           Contributions, or both) for the Plan Year in which
                           the excess occurred multiplied by a fraction and

                  (4)      the income or loss allocable to the Member's Elective
                           Deferral Contributions (and, if applicable, Qualified
                           Nonelective Contributions or Qualified Matching
                           Contributions, or both) for the gap period between
                           the end of such Plan Year and the date of
                           distribution multiplied by a fraction.

                  The numerator of the fractions is the Excess Contributions.
                  The denominator of the fraction in (3) above is the closing
                  balance without regard to any income or loss occurring during
                  such Plan Year (as of the end of such Plan Year) of the
                  Member's Account resulting from Elective Deferral
                  Contributions (and Qualified Nonelective Contributions or
                  Qualified Matching Contributions, or both, if used in
                  computing the Actual Deferral Percentage). The denominator of
                  the fraction in (4) above is the closing balance without
                  regard to any income or loss occurring during such gap period
                  (as of the end of such gap period) of the Member's Account
                  resulting from Elective Deferral Contributions (and Qualified
                  Nonelective Contributions or Qualified Matching Contributions,
                  or both, if used in computing the Actual Deferral Percentage).

                  Excess Contributions shall be distributed from the Member's
                  Account resulting from Elective Deferral Contributions. If
                  such Excess Contributions exceed the balance in the Member's
                  Account resulting from Elective Deferral Contributions, the
                  balance shall be distributed from the Member's Account
                  resulting from Qualified Matching Contributions (if
                  applicable) and Qualified Nonelective Contributions,
                  respectively.

         (d)      As of the end of each Plan Year, one of the following tests
                  must be met:

                  (1)      The Average Contribution Percentage for Eligible
                           Members who are Highly Compensated Employees for the
                           Plan Year is not more than the Average Contribution
                           Percentage for Eligible Members who are Nonhighly
                           Compensated Employees for the Plan Year multiplied by
                           1.25.

                  (2)      The Average Contribution Percentage for Eligible
                           Members who are Highly Compensated Employees for the
                           Plan Year is not more than the Average Contribution
                           Percentage for Eligible Members who are Nonhighly
                           Compensated Employees for the Plan Year multiplied by
                           2 and the difference between the Average Contribution
                           Percentages is not more than 2.

                  If one or more Highly Compensated Employees participate in
                  both a cash or deferred arrangement and a plan subject to the
                  Average Contribution Percentage test maintained by us or a
                  Controlled Group member and the sum of the Average Actual
                  Deferral Percentage and Average Contribution Percentage of
                  those Highly Compensated Employees subject to either or both
                  tests exceeds the Aggregate Limit, then the Contribution
                  Percentage of those Highly Compensated Employees who also
                  participate in a cash or deferred arrangement will be reduced
                  (beginning with such Highly Compensated Employees whose
                  Contribution Percentage is the highest) so that the limit is
                  not exceeded. The amount by which each Highly Compensated
                  Employee's Contribution Percentage is reduced shall be treated
                  as an Excess Aggregate Contribution. The Average Actual
                  Deferral Percentage and Average Contribution Percentage of the
                  Highly Compensated Employees are determined after any
                  corrections required to meet the Average Actual Deferral
                  Percentage and Average Contribution Percentage tests. Multiple
                  use does not occur if both the Average Actual Deferral
                  Percentage and Average Contribution Percentage of the Highly
                  Compensated Employees does not exceed 1.25 multiplied by the
                  Average Actual Deferral Percentage and Average Contribution
                  Percentage of the Nonhighly Compensated Employees.

                  The Contribution Percentage for any Eligible Member who is a
                  Highly Compensated Employee for the Plan Year and who is
                  eligible to have Contribution Percentage Amounts allocated to
                  his account under two or more plans described in Code Section
                  401(a) or arrangements described in Code Section 401(k) that
                  are maintained by us or a Controlled Group member shall be
                  determined as if the total of such Contribution Percentage
                  Amounts was made under each plan. If a Highly Compensated
                  Employee participates in two or more cash or deferred
                  arrangements that have different Plan Years, all cash or
                  deferred arrangements ending with or within the same calendar
                  year shall be treated as a single arrangement.

                  In the event that this Plan satisfies the requirements of Code
                  Section 410(b) only if aggregated with one or more other
                  plans, or if one or more other plans satisfy the requirements
                  of Code Section 410(b) only if aggregated with this Plan, then
                  this section shall be applied by determining the Contribution
                  Percentages of Eligible Members as if all such plans were a
                  single plan. For Plan Years beginning after December 31, 1989,
                  plans may be aggregated in order to satisfy Code Section
                  401(m) only if they have the same Plan Year.

                  For purposes of determining the Contribution Percentage of an
                  Eligible Member who is a five-percent owner or one of the ten
                  most highly-paid Highly Compensated Employees, the
                  Contribution Percentage Amounts and Pay of such Member shall
                  include Contribution Percentage Amounts and Pay for the Plan
                  Year of Family Members. Family Members, with respect to Highly
                  Compensated Employees, shall be disregarded as separate
                  employees in determining the Contribution Percentage both for
                  employees who are Nonhighly Compensated Employees and for
                  employees who are Highly Compensated Employees.

                  For purposes of determining the Contribution Percentage,
                  Member Contributions are considered to have been made in the
                  Plan Year in which contributed to the Plan. Matching
                  Contributions and Qualified Nonelective Contributions will be
                  considered made for a Plan Year if made no later than the end
                  of the twelve-month period beginning on the day after the
                  close of the Plan Year.

                  We shall maintain records sufficient to demonstrate
                  satisfaction of the Average Contribution Percentage test and
                  the amount of Qualified Nonelective Contributions or Qualified
                  Matching Contributions, or both, used in such test.

                  The determination and treatment of the Contribution Percentage
                  of any Member shall satisfy such other requirements as may be
                  prescribed by the Secretary of the Treasury.

                  Notwithstanding any other provisions of this Plan, Excess
                  Aggregate Contributions, plus any income and minus any loss
                  allocable thereto, shall be forfeited, if not vested, or
                  distributed, if vested, no later than the last day of each
                  Plan Year to Members to whose Accounts such Excess Aggregate
                  Contributions were allocated for the preceding Plan Year.
                  Excess Aggregate Contributions shall be allocated to Members
                  who are subject to the family member aggregation rules of Code
                  Section 414(q)(6) in the manner prescribed by the regulations.
                  If such Excess Aggregate Contributions are distributed more
                  than 2 1/2 months after the last day of the Plan Year in which
                  such excess amounts arose, a ten (10) percent excise tax will
                  be imposed on the employer maintaining the plan with respect
                  to those amounts. Excess Aggregate Contributions shall be
                  treated as Annual Additions under the Plan.

                  The Excess Aggregate Contributions shall be adjusted for
                  income or loss. The income or loss allocable to such Excess
                  Aggregate Contributions shall be equal to the sum of:

                  (3)      the income or loss allocable to the Member's
                           Contribution Percentage Amounts for the Plan Year in
                           which the excess occurred multiplied by a fraction
                           and

                  (4)      the income or loss allocable to the Member's
                           Contribution Percentage Amounts for the gap period
                           between the end of such Plan Year and the date of
                           distribution multiplied by a fraction.

                  The numerator of the fractions is the Excess Aggregate
                  Contributions. The denominator of the fraction in (3) above is
                  the closing balance without regard to any income or loss
                  occurring during such Plan Year (as of the end of such Plan
                  Year) of the Member's Account resulting from Contribution
                  Percentage Amounts. The denominator of the fraction in (4)
                  above is the closing balance without regard to any income or
                  loss occurring during such gap period (as of the end of such
                  gap period) of the Member's Account resulting from
                  Contribution Percentage Amounts.

                  Excess Aggregate Contributions shall be distributed from the
                  Member's Account resulting from Member Contributions that are
                  not required as a condition of employment or participation or
                  for obtaining additional benefits from Employer Contributions.
                  If such Excess Aggregate Contributions exceed the balance in
                  the Member's Account resulting from such Member Contributions,
                  the balance shall be forfeited, if not vested, or distributed,
                  if vested, on a pro-rata basis from the Member's Account
                  resulting from Contribution Percentage Amounts. If the
                  Adoption Agreement - Plus is used, these Forfeitures shall be
                  applied according to the provisions of Item O(7). If the
                  Adoption Agreement - Plus is not used, these Forfeitures shall
                  be used to offset the earliest Employer Contribution due after
                  the Forfeiture arises.

INVESTMENT OF CONTRIBUTIONS


SECTION 4.01  -  INVESTMENT OF CONTRIBUTIONS.

(a)      The provisions of this subsection apply to trusteed plans.

         All Contributions are forwarded by us to the Trustee to be deposited in
         the Trust Fund. Member Contributions shall be forwarded within three
         months after they are made.

         Investment of Contributions is governed by the provisions of the Trust,
         the Annuity Contract and any other funding arrangement in which the
         Trust Fund is or may be invested. To the extent permitted by the Trust,
         Annuity Contract, or other funding arrangement, the parties named in
         Item T of the Adoption Agreement shall direct the Contributions to any
         of the accounts available under the Trust and may request the transfer
         of assets resulting from those Contributions between such accounts. A
         Member may not direct the Trustee to invest the Member's Account in
         collectibles. Collectible means-any work of art, rug or antique, metal
         or gem, stamp or coin, alcoholic beverage or other tangible personal
         property specified by the Secretary of the Treasury. To the extent that
         a Member does not direct the investment of his Account, such Account
         shall be invested ratably in the accounts available under the Trust in
         the same manner as the undirected Accounts of all other Members. The
         Vested Accounts of all Inactive Members may be segregated and invested
         separately from the Accounts of all other Members.

         At least annually, the Named Fiduciary shall review all pertinent
         Employee information and Plan data in order to establish the funding
         policy of the Plan and to determine appropriate methods of carrying out
         the Plan's objectives. The Named Fiduciary shall inform the Trustee and
         any Investment Manager of the Plan's short-term and long-term financial
         needs so the investment policy can be coordinated with the Plan's
         financial requirements.

         However, the Named Fiduciary may delegate to the Investment Manager
         investment discretion for Contributions and Plan assets which are not
         subject to Member direction.

(b)      The provisions of this subsection apply to plans which are not
         trusteed.

         All Contributions are forwarded by us to the Insurer to be deposited
         under the Annuity Contract. Member Contributions shall be forwarded
         within three months after they are made.

         Investment of Contributions is governed by the provisions of the
         Annuity Contract. To the extent permitted by the Annuity Contract, the
         parties named in Item T of the Adoption Agreement shall direct the
         Contributions to any of the accounts available under the Annuity
         Contract and may request the transfer of assets resulting from those


                                      -45-

ARTICLE IV
<PAGE>   46
         Contributions between such accounts. To the extent that a Member does
         not direct the investment of his Account, such Account shall be
         invested ratably in the accounts available under the Annuity Contract
         in the same manner as the undirected Accounts of all other Members. The
         Vested Accounts of all Inactive Members may be segregated and invested
         separately from the Accounts of all other Members.

         At least annually, the Named Fiduciary shall review all pertinent
         Employee information and Plan data in order to establish the funding
         policy of the Plan and to determine appropriate methods of carrying out
         the Plan's objectives. The Named Fiduciary shall inform any Investment
         Manager of the Plan's short-term and long-term financial needs so the
         investment policy can be coordinated with the Plan's financial
         requirements.

         However, the Named Fiduciary may delegate to the Investment Manager
         investment discretion for Contributions and Plan assets which are not
         subject to Member direction.

SECTION 4.02  - PURCHASE OF INSURANCE.

If permitted under Item T of the Adoption Agreement, life insurance may be
purchased under this Plan for Active Members to provide incidental death
benefits. The purchase shall be subject to the provisions of this section, the
distribution of benefits provisions of Article VI, and the beneficiary
provisions of Section 9.06. If the Member has a spouse to whom he has been
continuously married for at least one year, such spouse shall be his Beneficiary
under the Insurance Policy unless (a) a qualified election has been made
according to the provisions of Section 6.03 or (b) the Trustee has been named as
Beneficiary. If the Trustee is named as Beneficiary, upon the death of the
Member, the Trustee shall be required to pay over all proceeds of the Insurance
Policy to the Member's Beneficiary or spouse, as the case may be, according to
the distribution of benefits provisions of Article VI.

The purchase of insurance shall be subject to the limitations that may be
imposed by the Insurer under the applicable Insurance Policy. The Insurance
Policy may provide for waiver of premium for disability.

The total of all insurance premiums for insurance coverage on the life of a
Member provided by our Contributions shall be limited to a percentage of all our
Contributions made for that Member. All such ordinary life insurance premiums
shall be limited to a percentage which is less than 50%. All such term life and
universal life insurance premiums shall be limited to a percentage which is not
more than 25%. If both ordinary life insurance and term life or universal life
insurance is purchased, 1/2 of all such ordinary life insurance premiums and all
such other life insurance premiums shall be limited to a percentage which is not
more than 25%. Ordinary life insurance policies are policies with both
nondecreasing death benefits and nonincreasing premiums. The Member's Account
resulting from deductible Voluntary Contributions (and nondeductible Voluntary
Contributions if the Adoption Agreement - Plus is not used) shall not be applied
to pay life insurance premiums.

Any dividends declared upon an amount of insurance in force on the life of a
Member may, within the terms of the Insurance Policy, be applied to reduce the
earliest premium due, purchase


                                      -46-

ARTICLE IV
<PAGE>   47
paid-up insurance coverage, accumulate under the policy to provide additional
death benefit or be credited to the Member's Account which is included in the
Investment Fund. In the absence of any direction, such dividends shall be
applied to reduce the earliest premium due for such amount of insurance.

A Member may elect to have amounts deducted from his Account to pay insurance
premiums. The total amount deducted cannot exceed the amount of Contributions
credited to his Account which were not used to provide insurance, but could have
been.

If a decrease in the amount of life insurance is necessary, any cash values of
the terminated insurance shall be retained in the Member's Account and added to
the Investment Fund.

SECTION 4.03  -  TRANSFER OF OWNERSHIP.

Any transfer of ownership under this section shall be subject to the
distribution of benefits provisions of Article VI.

Upon the request of a Member, we may purchase for its cash value a personal life
insurance policy issued to, and insuring the life of, the Member. Such policy
shall be immediately transferred from us to the Trustee. The cash value of the
purchased policy shall be a part of our Contribution for the Plan Year. Any such
purchase shall be accomplished only under an appropriate written agreement
between the Member, the Trustee and us. In lieu of our purchase of such policy
and at our direction, the Trustee may purchase the policy directly from the
Member. These provisions shall not be available if the policy is subject to a
policy loan or similar lien. The purchase of and future premiums for any such
policy shall be subject to the limitations in Section 4.02.

If the Insurance Policy allows, a Member may pay the Trustee an amount equal to
the cash values of any Insurance Policy on his life. Such payment shall become a
part of his Account. Upon receiving the payment, the Trustee shall transfer
ownership of the policy to the Member. This transfer of ownership is not a
distribution from the Plan. This option shall only be available to a Member if
the policy would, but for the sale, be surrendered by the Plan.

If distribution of a Member's Vested Account would include the cash values of an
Insurance Policy on his life, the Member may have ownership of an Insurance
Policy on his life transferred to him without making payment to the Trustee if
permitted by such Insurance Policy. Any Insurance Policy transferred to the
Member for which he has not made payment to the Trustee is a distribution from
the Plan.

In applying the provisions of this section, all Members in similar circumstances
shall be treated in a similar manner. Members who are Highly Compensated
Employees (officers, shareholders or highly compensated Employees before the
first Yearly Date after December 31, 1988) shall not be treated in a manner more
favorable than that afforded all other Members.

SECTION 4.04  -  TERMINATION OF INSURANCE.


                                      -47-

ARTICLE IV
<PAGE>   48
The termination of insurance under this section shall be subject to the
distribution of benefits provisions of Article VI.

No premium payments shall be made under this Plan for an Inactive Member. If a
Member becomes an Inactive Member before Retirement Date, the Trustee may either
use the cash values of the Insurance Policy on his life to provide paid-up
insurance or may surrender the Insurance Policy. The cash values of a
surrendered Insurance Policy are retained in the Member's Account and added to
the Investment Fund. The purchase of paid-up insurance shall be subject to the
provisions of the Insurance Policy. If the Member ceases to be an Employee
before Retirement Date, the Member may elect to have the ownership of the
Insurance Policy transferred as provided in Section 4.03.

On a Member's Retirement Date, any Insurance Policy on his life, the ownership
of which has not been transferred to him, shall terminate. The cash values shall
be paid to the Member in cash or applied to provide an income for him according
to the provisions of the Insurance Policy. In any event, no portion of the value
of any Insurance Policy shall be used to continue life insurance protection
under the Plan beyond actual retirement.

BENEFITS


SECTION 5.01  -  RETIREMENT BENEFITS.

On a Member's Retirement Date, the Member's Vested Account shall be distributed
to the Member according to the distribution of benefits provisions of Article VI
and the small amounts provisions of Section 9.11.

SECTION 5.02  -  DEATH BENEFITS.

If a Member dies before his Annuity Starting Date, the Member's Vested Account
shall be distributed according to the distribution of benefits provisions of
Article VI and the small amounts provisions of Section 9.11.

SECTION 5.03  -  VESTED BENEFITS.

If the Inactive Member's Vested Account is not payable under the small amounts
provisions of 9.11, he may elect, but is not required, to receive in a single
sum that part of his Vested Account which results from Member Contributions
after he ceases to be an Employee. The Member's election shall meet the consent
requirements in Section 6.03 for a qualified election of a benefit payable in a
form other than a Qualified Joint and Survivor Form.

If the Inactive Member's Vested Account is not payable under the small amounts
provisions of Section 9.11, he may elect, but is not required, to receive a
distribution of his Vested Account after he ceases to be an Employee. If Item
X(3)(a) of the Adoption Agreement - Plus is selected, distributions from the
Member's Vested Account which results from the designated Contributions shall
not begin before the Member retires, becomes Totally Disabled or dies. If Item
X(3)(b) of the Adoption Agreement - Plus is selected, distributions shall not be
made until he has ceased to be an Employee for the period of time selected in
Item X(3)(b). The Member's election shall be subject to his spouse's consent as
provided in Section 6.03. A distribution under this paragraph will be a
retirement benefit and shall be distributed to the Member according to the
provisions of Article VI.

If an Inactive Member does not receive an earlier distribution according to the
provisions of the preceding paragraph or the small amounts provisions of Section
9.11, upon his Retirement Date or death, his Vested Account shall be applied
according to the provisions of Section 5.01 or 5.02.

A Member may not receive any such distribution under the provisions of this
section after he again becomes an Employee until he subsequently ceases to be an
Employee and again meets the requirements of this section.

Some or all of an Inactive Member's Vested Account may be transferred directly
to the trustee, named fiduciary, or insurer under the retirement plan of the
Inactive Member's current employer if the following requirements are met: the
Inactive Member would be eligible to receive a


                                      -49-

ARTICLE V
<PAGE>   50
distribution of his Vested Account at the time the transfer is to occur; the
amount transferred, if distributed to the Member, would qualify as a rollover
contribution which the Code permits to be transferred to a plan that meets the
requirements of Code Section 401(a); the current employer's plan meets the
requirements of Code Section 401(a). The Member must request the transfer in
writing. The trustee, named fiduciary or insurer under the plan must be willing
to accept such a transfer. Such transferred amount shall be treated as a
distribution under this plan.

The Nonvested Account of an Inactive Member shall remain a part of his Account
until it becomes a Forfeiture; provided, however, if the Inactive Member again
becomes an Employee so that his Vesting Percentage may increase, the Nonvested
Account may become part of his Vested Account.

SECTION 5.04  -  WHEN BENEFITS BEGIN.

Benefits under the Plan begin when a Member retires, dies or ceases to be an
Employee, whichever applies, as provided in the preceding sections of this
article. Benefits which begin before Normal Retirement Date for a Member who
became Totally Disabled when he was an Employee shall be deemed to begin because
he is Totally Disabled. The start of benefits is subject to the qualified
election procedures of Article VI.

Unless otherwise elected, benefits shall begin before the sixtieth day following
the close of the Plan Year in which the latest date below occurs:

(a)      The date the Member attains the earlier of (i) age 65 or (ii) the later
         of Normal Retirement Age or age 62.

(b)      The tenth anniversary of the Member's Entry Date.

(c)      The date the Member ceases to be an Employee.

Notwithstanding the foregoing, the failure of a Member and spouse to consent to
a distribution while a benefit is immediately distributable, within the meaning
of Section 6.03, shall be deemed to be an election to defer commencement of
payment of any benefit sufficient to satisfy this section.

The Member may elect to have benefits begin after the latest date for beginning
benefits described above, subject to the following provisions of this section.
The Member shall make the election in writing and deliver the signed election to
the Plan Administrator before Normal Retirement Date or the date he ceases to be
an Employee, if later. The election must describe the form of distribution and
the date benefits will begin. The Member shall not elect a date for beginning
benefits or a form of distribution which would result in a benefit payable when
he dies which would be more than incidental within the meaning of governmental
regulations.

Benefits shall begin by the Member's Required Beginning Date, as defined in
Section 6.02. Distribution of the Vested Account resulting from Contributions
made after the Member's


                                      -50-

ARTICLE V
<PAGE>   51
Required Beginning Date shall begin by the April I following the calendar year
in which such Contributions were made.

If a Member receives a taxable distribution (including a withdrawal) of any part
of his Vested Account, he may be subject to a Federal tax penalty. The tax
penalty does not apply if the distribution is:

(a)     made on or after age 59 1/2;

(b)     made on account of the Member's death to his Beneficiary or estate;

(c)     made on account of being disabled;

(d)     part of a series of periodic payments after separation from service that
        are substantially equal, at least annual, and based on the life
        expectancy of the Member or the Member and his Beneficiary; or

(e)      made after separation from service after the attainment of age 55.

In addition, no tax is imposed on amounts received and paid during the taxable
year for medical expenses in an amount not to exceed that deductible under Code
Section 213. Disabled means that a Member is disabled to the extent he is unable
to engage in any substantial gainful activity by reason of any medically
determinable physical or mental impairment which can be expected to result in
death or be of long-continued and indefinite duration. Proof of the existence of
the disability will be in such form and manner as the Secretary of the Treasury
may require.

Contributions which are used to compute the Actual Deferral Percentage, as
defined in Section 3.07, (Elective Deferral Contributions, Qualified Nonelective
Contributions, and Qualified Matching Contributions) may be distributed upon
disposition by us of substantially all of the assets used by us in a trade or
business or disposition by us of our interest in a subsidiary if the transferee
corporation is not a Controlled Group member, the Employee continues employment
with the transferor corporation and the transferor corporation continues to
maintain the Plan. The distribution must be a total distribution.

SECTION 5.05  -  WITHDRAWAL BENEFITS.

(a)      Distributions on Account of Financial Hardship

         If elected by us in Item W(2) of the Adoption Agreement, withdrawals of
         part of the Member's Account as provided in Item W(2) will be permitted
         in the event of hardship due to an immediate and heavy financial need.

         Immediate and heavy financial need shall be limited to: (i) medical
         expenses described in Code Section 213(d) incurred by the Member, the
         Member's spouse, or any dependents of the Member (as defined in Code
         Section 152); (ii) purchase (excluding mortgage payments) of a
         principal residence for the Member; (iii) payment of tuition for the
         next


                                      -51-

ARTICLE V
<PAGE>   52
         semester or quarter of post-secondary education for the Member, his
         spouse, children or dependents; (iv) the need to prevent the eviction
         of the Member from his principal residence or foreclosure on the
         mortgage of the Member's principal residence; or (v) any other
         distribution which is deemed by the Commissioner of Internal Revenue to
         be made on account of immediate and heavy financial need as provided in
         Treasury regulations. The Member's request for a withdrawal shall
         include his written statement that an immediate and heavy financial
         need exists and explain its nature.

         No withdrawal shall be allowed which is not necessary to satisfy such
         immediate and heavy financial need. Such withdrawal shall be deemed
         necessary only if all of the following requirements are met: (i) the
         distribution is not in excess of the amount of the immediate and heavy
         financial need of the Member; (ii) the Member has obtained all
         distributions, other than hardship distributions, and all nontaxable
         loans currently available under all plans maintained by us; (iii) the
         Plan, and all other plans maintained by us, provide that the Member's
         elective contributions and employee contributions will be suspended for
         at least 12 months after receipt of the hardship distribution; and (iv)
         the Plan, and all other plans maintained by us, provide that the Member
         may not make elective contributions for the Member's taxable year
         immediately following the taxable year of the hardship distribution in
         excess of the applicable limit under Code Section 402(g) for such next
         taxable year less the amount of such Member's elective contributions
         for the taxable year of the hardship distribution. The Plan will
         suspend elective contributions and employee contributions for 12 months
         and limit elective deferrals as provided in the preceding sentence. A
         Member shall not cease to be an Eligible Member, as defined in Section
         3.07, merely because his elective contributions or employee
         contributions are suspended.

(b)      Distributions on Account of Other Withdrawals

         A Member may withdraw in a single sum any part of his Account resulting
         from his Voluntary Contributions subject to the limitations provided in
         Item W(1). If selected by us in Item W(3), withdrawals of the Member's
         Account as provided in Item W(3) will be permitted at any time after he
         attains age 59 1/2 subject to the limitations provided in Item W(3). If
         selected by us in Item W(4) of the Adoption Agreement - Plus,
         withdrawals of part of the Member's Account as provided in Item W(4)
         will be permitted after he has been an Active Member for at least 5
         years subject to the limitations provided in Item W(4).

A request for withdrawal shall be in writing on a form furnished for that
purpose and delivered to the Plan Administrator before the withdrawal is to
occur. Withdrawals shall be subject to the qualified election provisions of
Article VI. A forfeiture shall not occur solely as a result of a withdrawal.

SECTION 5.06  -  LOANS TO MEMBERS.

Loans shall be made available to all Members on a reasonably equivalent basis.
For purposes of this section, Member means any Member or Beneficiary who is an
Employee. Loans shall not be


                                      -52-


ARTICLE V
<PAGE>   53
made to highly compensated employees, as defined in Code Section 414(q), in an
amount greater than the amount made available to other Members.

No loans will be made to any shareholder-employee or owner-employee. For
purposes of this requirement, a shareholder-employee means an employee or
officer of an electing small business (Subchapter S) corporation who owns (or is
considered as owning within the meaning of Code Section 318(a)(1)), on any day
during the taxable year of such corporation, more than 5% of the outstanding
stock of the corporation.

A loan to a Member shall be a Member-directed investment of his Account. The
loan is a Trust investment but no Account other than the borrowing Member's
Account shall share in the interest paid on the loan or bear any expense or loss
incurred because of the loan.

The number of outstanding loans shall be limited to one, unless otherwise
specified in Item T(b)(vi). No more than one loan will be approved for any
Member in any 12-month period, unless otherwise specified in Item T(b)(vii). The
minimum amount of any loan shall be selected in Item T(b)(iv).

Loans must be adequately secured and bear a reasonable rate of interest.

The amount of the loan shall not exceed the maximum amount that may be treated
as a loan under Code Section 72(p) (rather than a distribution) to the Member
and shall be equal to the lesser of (a) or (b) below:

         (a)      $50,000 reduced by the highest outstanding loan-balance of
                  loans during the one-year period ending on the day before the
                  new loan is made.

         (b)      The greater of (i) or (ii), reduced by (iii) below:

                  (i)      One-half of the Member's Vested Account.

                  (ii)     $10,000.

                  (iii)    Any outstanding loan balance on the date the new loan
                           is made.

For purposes of this maximum, a Member's Vested Account does not include any
accumulated deductible employee contributions, as defined in Code Section
72(o)(5)(B), and all qualified employer plans, as defined in Code Section
72(p)(4), of ours and any Controlled Group member shall be treated as one plan.

The foregoing notwithstanding, the amount of such loan shall not exceed 50% of
the amount of the Member's Vested Account reduced by any outstanding loan
balance on the date the new loan is made. In addition, the amount of the loan
may be further limited to a specified dollar amount, if Item T(b)(v) so
indicates. No collateral other than a portion of the Member's Vested Account


                                      -53-

(as limited above) shall be accepted. The Loan Administrator shall determine if
the collateral is adequate for the amount of the loan requested.

A Member must obtain the consent of the Member's spouse, if any, to the, use of
the Vested Account as security for the loan. Spousal consent shall be obtained
no earlier than the beginning of the 90-day period that ends on the date on
which the loan to be so secured is made. The consent must be in writing, must
acknowledge the effect of the loan, and must be witnessed by a plan
representative or a notary public. Such consent shall thereafter be binding with
respect to the consenting spouse or any subsequent spouse with respect to that
loan. A new consent shall be required if the Vested Account is used for
collateral upon renegotiation, extension, renewal, or other revision of the
loan.

If a valid spousal consent has been obtained in accordance with the above, then,
notwithstanding any other provision of this Plan, the portion of the Member's
Vested Account used as a security interest held by the Plan by reason of a loan
outstanding to the Member shall be taken into account for purposes of
determining the amount of the Vested Account payable at the time of death or
distribution, but only if the reduction is used as repayment of the loan. If
less than 100% of the Member's Vested Account (determined without regard to the
preceding sentence) is payable to the surviving spouse, then the Vested Account
shall be adjusted by first reducing the Vested Account by the amount of the
security used as repayment of the loan, and then determining the benefit payable
to the surviving spouse.

Each loan shall bear a reasonable fixed rate of interest to be determined by the
Loan Administrator. In determining the interest rate, the Loan Administrator
shall take into consideration fixed interest rates currently being charged by
commercial lenders for loans of comparable risk on similar terms and for similar
durations, so that the interest will provide for a return commensurate with
rates currently charged by commercial lenders for loans made under similar
circumstances. The Loan Administrator shall not discriminate among Members in
the matter of interest rates; but loans granted at different times may bear
different interest rates in accordance with the current appropriate standards.

The loan shall by its terms require that repayment (principal and interest) be
amortized in level payments, not less frequently than quarterly, over a period
not extending beyond five years from the date of the loan. The period of
repayment for any loan shall be arrived at by mutual agreement between the Loan
Administrator and the Member.

The Member shall make a written application for a loan from the Plan on forms
provided by the Loan Administrator. The application must specify the amount and
duration requested. No loan will be approved unless the Member is creditworthy.
The Member must grant authority to the Loan Administrator to investigate the
Member's creditworthiness so that the loan application may be properly
considered.

Information contained in the application for the loan concerning the income,
liabilities, and assets of the Member will be evaluated to determine whether
there is a reasonable expectation that the Member will be able to satisfy
payments on the loan as due. Additionally, the Loan


                                      -54-

ARTICLE V
<PAGE>   55
Administrator will pursue any appropriate further investigations concerning the
creditworthiness and/or credit history of the Member to determine whether a loan
should be approved.

Each loan shall be fully documented in the form of a promissory note signed by
the Member for the face amount of the loan, together with interest determined as
specified above.

There will be an assignment of collateral to the Plan executed at the time the
loan is made.

In those cases where repayment through payroll deduction by us is available,
installments are so payable, and a payroll deduction agreement will be executed
by the Member at the time of making the loan.

Where payroll deduction is not available, payments are to be timely made.

Any payment that is not by payroll deduction shall be made payable to us or the
Trustee, as specified in the promissory note, and delivered to the Loan
Administrator, including prepayments, service fees and penalties, if any, and
other amounts due under the note.

The promissory note may provide for reasonable late payment penalties and/or
service fees. Any penalties or service fees shall be applied to all Members in a
nondiscriminatory manner. If the promissory note so provides, such amounts may
be assessed and collected from the Account of the Member as part of the loan
balance.

Each loan may be paid prior to maturity, in part or in full, without penalty or
service fee, except a may be set out in the promissory note.

If any amount remains unpaid for more than 31 days after due, a default is
deemed to occur.

Upon default, the Plan has the right to pursue any remedy available by law to
satisfy the amount due, along with accrued interest, including the right to
enforce its claim against the security pledged and execute upon the collateral
as allowed by law.

If any payment of principal or interest or any other amount due under the
promissory note, or any portion thereof, is not made for a period of 90 days
after due, the entire principal balance whether or not otherwise then due, shall
become immediately due and payable without demand or notice, and subject to
collection or satisfaction by any lawful means, including specifically but not
limited to the right to enforce the claim against the security pledged and to
execute upon the collateral as allowed by law.

In the event of default, foreclosure on the note and attachment of security or
use of amounts pledged to satisfy the amount then due, will not occur until a
distributable event occurs in accordance with the Plan, and will not occur to an
extent greater than the amount then available upon any distributable event which
has occurred under the Plan.

All reasonable costs and expenses, including but not limited to attorney's fees,
incurred by the Plan in connection with any default or in any proceeding to
enforce any provision of a


                                      -55-

ARTICLE V
<PAGE>   56
promissory note or instrument by which a promissory note for a Member loan is
secured, shall be assessed and collected from the Account of the Member as part
of the loan balance.

If payroll deduction is being utilized, in the event that a Member's available
payroll deduction amounts in any given month are insufficient to satisfy the
total amount due, there will be an increase in the amount taken subsequently,
sufficient to make up the amount that is then due. If the subsequent deduction
is also insufficient to satisfy the amount due within 31 days, a default is
deemed to occur as above. If any amount remains past due more than 90 days, the
entire principal amount, whether or not otherwise then due, along with interest
then accrued and any other amount then due under the promissory note, shall
become due and payable, as above.

If the Member ceases to be an Employee, the balance of the outstanding loan
becomes due and payable, and the Member's Vested Account will be used as
available for distribution(s) to pay the outstanding loan. The Member's Vested
Account will not be used to pay any amount due under the outstanding loan before
the date which is 31 days after the date he ceased to be an Employee, and the
Member may elect to repay the outstanding loan with interest on the day of
repayment. If no distributable event has occurred under the Plan at the time
that the Member's Vested Account would otherwise be used under this provision to
pay any amount due under the outstanding loan, this will not occur until the
time, or in excess of the extent to which, a distributable event occurs under
the Plan.

DISTRIBUTION OF BENEFITS

The provisions of this article shall apply on or after August 23, 1984, to any
Member who is credited with at least one Hour of Service or one hour of paid
leave on or after that date and to such other Members as provided in Section
6.05. If the Effective Date of our Plan is before January 1, 1984, the
provisions of the Prior Plan as in effect on the day before the TEFRA Compliance
Date shall apply before August 23, 1984. If the Effective Date of our Plan is on
or after January 1, 1984, and before August 23, 1984, the provisions of the Plan
as originally adopted shall apply before August 23, 1984.

SECTION 6.01  -  AUTOMATIC FORMS OF DISTRIBUTION.

Unless a qualified election of an optional form of benefit has been made within
the election period (see Section 6.03), the automatic form of benefit payable to
or on behalf of a Member is determined as follows:

(a)      The automatic form of retirement benefit for a Member who does not die
         before his Annuity Starting Date shall be the Qualified Joint and
         Survivor Form.

(b)      The automatic form of death benefit for a Member who dies before his
         Annuity Starting Date shall be:

         (1)      A Qualified Preretirement Survivor Annuity for a Member who
                  has a spouse to whom he has been continuously married
                  throughout the one-year period ending on the date of his
                  death. The spouse may elect to start receiving the death
                  benefit on any first day of the month on or after the Member
                  dies and by the date the Member would have been age 70 1/2. If
                  the spouse dies before benefits start, the Member's Vested
                  Account, determined as of the date of the spouse's death,
                  shall be paid to the spouse's Beneficiary.

         (2)      A single sum payment to the Member's Beneficiary for a Member
                  who does not have a spouse who is entitled to a Qualified
                  Preretirement Survivor Annuity.

         Before a death benefit will be paid on account of the death of a Member
         who does not have a spouse who is entitled to a Qualified Preretirement
         Survivor Annuity, it must be established to the satisfaction of a plan
         representative that the Member does not have such a spouse.

SECTION 6.02  -  OPTIONAL FORMS OF DISTRIBUTION AND DISTRIBUTION REQUIREMENTS.

                  Beneficiary) as of the Member's (or Designated Beneficiary's)
                  birthday in the applicable calendar year reduced by one for
                  each calendar year which has elapsed since the date Life
                  Expectancy was first calculated. If Life Expectancy is being
                  recalculated, the Applicable Life Expectancy shall be the Life
                  Expectancy so recalculated. The applicable calendar year shall
                  be the first Distribution Calendar Year, and if Life
                  Expectancy is being recalculated such succeeding calendar

                  as to the Member (or spouse) and shall apply to all subsequent
                  years. The life expectancy of a nonspouse Beneficiary may not
                  be recalculated.

                  LIFE EXPECTANCY means life expectancy computed by use of the
                  expected return multiples in Tables V and VI of section 1.72-9
                  of the Income Tax Regulations.

                  Unless otherwise elected by the Member (or spouse, in the case
                  of distributions described in (e)(2)(ii) below) by the time
                  distributions are required to begin, life expectancies shall
                  be recalculated annually. Such election shall be irrevocable
                  as to the Member (or spouse) and shall apply to all subsequent
                  years. The life expectancy of a nonspouse Beneficiary may not

                           Distribution Calendar Year (valuation calendar year)
                           increased by the amount of any contributions or
                           forfeitures allocated to the Account balance as of
                           the dates in the valuation calendar year after the
                           valuation date and decreased by distributions made in
                           the valuation calendar year after the valuation date.

                  (2)      For purposes of (1) above, if any portion of the
                           minimum distribution for the first Distribution
                           Calendar Year is made in the second Distribution
                           Calendar Year on or before the Required Beginning
                           Date, the amount of the minimum distribution made in
                           the second Distribution Calendar Year shall be
                           treated as if it had been made in the immediately
                           preceding Distribution Calendar Year.

                  REQUIRED BEGINNING DATE means, for a Member, the first day of

                           age 70 1/2 before January 1, 1988, and who is not a
                           5-percent owner is the first day of April of the
                           calendar year following the calendar year in which
                           the later of retirement or attainment of age 70 1/2
                           occurs.

                  (2)      The Required Beginning Date for a Member who attains
                           age 70 1/2 before January 1, 1988, and who is a
                           5-percent owner is the first day of April of the
                           calendar year following the later of

                           (i)      the calendar year in which the Member
                                    attains age 70 1/2, or

                           (ii)     the earlier of the calendar year with or
                                    within which ends the Plan Year in which the

                                    calendar year in which the Member retires.

                  (3)      The Required Beginning Date of a Member who is not a

                           is April 1, 1990.

                  A Member is treated as a 5-percent owner for purposes of this
                  section if such Member is a 5-percent owner as defined in Code
                  Section 416(i) (determined in accordance with Code Section 416
                  but without regard to whether the Plan is top-heavy) at any

                  year in which such owner attains age 66 1/2 or any subsequent
                  Plan Year.

                  Once distributions have begun to a 5-percent owner under this
                  section, they must continue to be distributed, even if the
                  Member ceases to be a 5-percent owner in a subsequent year.

         (b)      The optional forms of retirement benefit shall be the

                  Beneficiary as provided in (d) below where the Life Expectancy
                  is not recalculated; and a series of installments chosen by
                  the Member with a minimum payment each year beginning with the
                  year the Member turns age 70 1/2. The payment for the first
                  year in which a minimum payment is required will be made by
                  April 1 of the following calendar year. The payment for the
                  second year and each successive year will be made by December
                  31 of that year. The minimum payment will be based on a period
                  equal to the Joint and Last Survivor Expectancy of the Member
                  and the Member's spouse, if any, as provided in (d) below
                  where the Joint and Last Survivor Expectancy is recalculated.
                  The balance of the Member's Vested Account, if any, will be
                  payable on the Member's death to his Beneficiary in a single
                  sum. If not prohibited in Item Y of the Adoption Agreement
                  --Plus, a single sum payment is also available.

                  Election of an optional form is subject to the qualified
                  election provisions of Article VI.

                  Any annuity contract distributed shall be nontransferable. The
                  terms of any annuity contract purchased and distributed by the
                  Plan to a Member or spouse shall comply with the requirements
                  of this Plan.

         (c)      The optional forms of death benefit are a single sum payment
                  and any annuity that is an optional form of retirement
                  benefit. However, a series of installments shall not be
                  available if the Beneficiary is not the spouse of the deceased
                  Member.

         (d)      Subject to Section 6.01, joint and survivor annuity
                  requirements, the requirements of this section shall Apply to
                  any distribution of a Member's interest and will take
                  precedence over any inconsistent provisions of this Plan.
                  Unless otherwise specified, the provisions of this section
                  apply to calendar years beginning after December 31, 1984.

                  All distributions required under this section shall be
                  determined and made in accordance with the proposed
                  regulations under Code Section 401(a)(9), including the
                  minimum distribution incidental benefit requirement of section
                  1.401(a)(9)-2 of the proposed regulations.

                  The entire interest of a Member must be distributed or begin
                  to be distributed no later than the Member's Required
                  Beginning Date.

                  As of the first Distribution Calendar Year, distributions, if
                  not made in a single sum, may only be made over one of the

                                             which the Member would have
                                             attained age 70 1/2.

                           If the Member has not made an election pursuant to
                           this (e)(2) by the time of his death, the Member's
                           Designated Beneficiary must elect the method of
                           distribution no later than the earlier of

                           (iii)    December 31 of the calendar year in which
                                    distributions would be required to begin

                                    contains the fifth anniversary of the date
                                    of death of the Member.

                           If the Member has no Designated Beneficiary, or if
                           the Designated Beneficiary does not elect a method of
                           distribution, distribution of the Member's entire
                           interest must be completed by December 31 of the
                           calendar year containing the fifth anniversary of the

                  (3)      For purposes of (e)(2) above, if the surviving spouse

                           the exception of (e)(2)(ii) therein, shall be applied

                  (4)      For purposes of this (e), any amount paid to a child
                           of the Member will be treated as if it had been paid
                           to the surviving spouse if the amount becomes payable
                           to the surviving spouse when the child reaches the
                           age of majority.

                  (5)    For purposes of this (e), distribution of a Member's
                         interest is considered to begin on the Member's
                         Required Beginning Date (or if (e)(3) above is
                         applicable, the date distribution is required to begin
                         to the surviving spouse pursuant to (e)(2) above). If
                         distribution in the form of an annuity irrevocably
                         commences to the Member before the Required Beginning
                         Date, the date distribution is considered to begin is
                         the date distribution actually commences.

SECTION 6.03  -  ELECTION PROCEDURES.

The Member, Beneficiary, or spouse shall make any election under this section in
writing. The Plan Administrator may require such individual to complete and sign
any necessary documents as to the provisions to be made. Any election permitted
under (a) and (b) below shall be subject to the qualified election provisions of
(c) below.

(a)      Retirement Benefits. A Member may elect his Beneficiary or Contingent
         Annuitant and may elect to have retirement benefits distributed under
         any of the optional forms of retirement benefit described in Section
         6.02.


                                      -63-

<PAGE>   64
(b)      Death Benefits. A Member may elect his Beneficiary and may elect to
         have death benefits distributed under any of the optional forms of
         death benefit described in Section 6.02.

         If the Member has not elected an optional form of distribution for the
         death benefit payable to his Beneficiary, the Beneficiary may, for his
         own benefit, elect the form of distribution, in like manner as a
         Member.

         The Member may waive the Qualified Preretirement Survivor Annuity by
         naming someone other than his spouse as Beneficiary.

         In lieu of the Qualified Preretirement Survivor Annuity described in
         Section 6.01, the spouse may, for his own benefit, waive the Qualified
         Preretirement Survivor Annuity by electing to have the benefit
         distributed under any of the optional forms of death benefit described
         in Section 6.02.

  (c)    Qualified Election. The Member, Beneficiary or spouse may make an
         election at any time during the election period. The Member,
         Beneficiary, or spouse may revoke the election made (or make a new
         election) at any time and any number of times during the election
         period. An election is effective only if it meets the consent
         requirements below.

         The election period as to retirement benefits is the 90-day period
         ending on the Annuity Starting Date. An election to waive the Qualified
         Joint and Survivor Form may not be made before the date he is provided
         with the notice of the ability to waive the Qualified Joint and
         Survivor Form. If the Member elects the series of installments, he may
         elect on any later date to have the balance of his Vested Account paid
         under any of the optional forms of retirement benefit available under
         the Plan. His election period for this election is the 90-day period
         ending on the Annuity Starting Date for the optional form of retirement
         benefit elected.

         A Member may make an election as to death benefits at any time before
         he dies. The spouse's election period begins on the date the Member
         dies and ends on the date benefits begin. The Beneficiary's election
         period begins on the date the Member dies and ends on the date benefits
         begin. An election to waive the Qualified Preretirement Survivor
         Annuity may not be made by the Member before the date he is provided
         with the notice of the ability to waive the Qualified Preretirement
         Survivor Annuity. A Member's election to waive the Qualified
         Preretirement Survivor Annuity which is made before the first day of
         the Plan Year in which he reaches age 35 shall become invalid on such
         date. An election made by a Member after he ceases to be an Employee
         will not become invalid on the first day of the Plan Year in which he
         reaches age 35 with respect to death benefits from that part of his
         Account resulting from Contributions made before he ceased to be an
         Employee.

         If the Member's Vested Account has at any time exceeded $3,500, any
         benefit which is (1) immediately distributable or (2) payable in a form
         other than a Qualified Joint and


                                      -64-

<PAGE>   65
         Survivor Form or a Qualified Preretirement Survivor Annuity requires
         the consent of the Member and the Member's spouse (or where either the
         Member or the spouse has died, the survivor). The consent of the Member
         or spouse to a benefit which is immediately distributable must not be
         made before the date the Member or spouse is provided with the notice
         of the ability to defer the distribution. Such consent shall be made in
         writing. The consent shall not be made more than 90 days before the
         Annuity Starting Date. Spousal consent is not required for a benefit
         which is immediately distributable in a Qualified Joint and Survivor
         Form. Furthermore, if spousal consent is not required because the
         Member is electing an optional form of retirement benefit that is not a
         life annuity pursuant to (d) below, only the Member need consent to the
         distribution of a benefit payable in a form that is not a life annuity
         and which is immediately distributable. Neither the consent of the
         Member nor the Member's spouse shall be required to the extent that a
         distribution is required to satisfy Code Section 401(a)(9) or Code
         Section 415. A benefit is immediately distributable if any part of the
         benefit could be distributed to the Member (or surviving spouse) before
         the Member attains (or would have attained if not deceased) the older
         of Normal Retirement Age or age 62. If the Qualified Joint and Survivor
         Form is waived, the spouse has the right to limit consent only to a
         specific Beneficiary or a specific form of benefit. The spouse can
         relinquish one or both such rights. Such consent shall be made in
         writing. The consent shall not be made more than 90 days before the
         Annuity Starting Date. If the Qualified Preretirement Survivor Annuity
         is waived, the spouse has the right to limit consent only to a specific
         Beneficiary. Such consent shall be in writing. The spouse's consent
         shall be witnessed by a plan representative or notary public. The
         spouse's consent must acknowledge the effect of the election, including
         that the spouse had the right to limit consent only to a specific
         Beneficiary or a specific form of benefit, if applicable, and that the
         relinquishment of one or both such rights was voluntary. Unless the
         consent of the spouse expressly permits designations by the Member
         without a requirement of further consent by the spouse, the spouse's
         consent must be limited to the form of benefit, if applicable, and the
         Beneficiary (including any Contingent Annuitant), class of
         Beneficiaries, or contingent Beneficiary named in the election. Spousal
         consent is not required, however, if the Member establishes to the
         satisfaction of the plan representative that the consent of the spouse
         cannot be obtained because there is no spouse or the spouse cannot be
         located. A spouse's consent under this paragraph shall not be valid
         with respect to any other spouse. A Member may revoke a prior election
         without the consent of the spouse. Any new election will require a new
         spousal consent, unless the consent of the spouse expressly permits
         such election by the Member without further consent by the spouse. A
         spouse's consent may be revoked at any time within the Member's
         election period.

         Before the first Yearly Date in 1989, the Member's Account which
         results from deductible Voluntary Contributions shall not be taken into
         account in determining whether the Member's Vested Account has exceeded
         $3,500 and an election as to the distribution of a Member's Vested
         Account which results from deductible Voluntary Contributions is not
         subject to the consent requirements above and may be made any time
         before such distribution is to begin.

  (d)    Special Rule for Profit Sharing Plans. As provided in the preceding
         provisions of the Plan, if a Member has a spouse to whom he has been
         continuously married throughout the one-year period ending on the date
         of the Member's death, the Member's Vested Account, including the
         proceeds payable under any Insurance Policy on the Member's life, shall
         be paid to such spouse. However, if there is no such spouse or if the
         surviving spouse has already consented in a manner conforming to the
         qualified election requirements in (c) above, the Vested Account shall
         be payable to the Member's Beneficiary in the event of the Member's
         death.

         The Member may waive the spousal death benefit described above at any
         time provided that no such waiver shall be effective unless it
         satisfies the conditions of (c) above (other than the notification
         requirement referred to therein) that would apply to the Member's
         waiver of the Qualified Preretirement Survivor Annuity.

         This subsection (d) applies if with respect to the Member, the Plan is
         not a direct or indirect transferee after December 31, 1984, of a
         defined benefit plan, money purchase plan (including a target plan),
         stock bonus or profit sharing plan which is subject to the survivor
         annuity requirements of Code Section 401(a)(11) and Code Section 417.
         If the above condition is met, spousal consent is not required for
         electing an optional form of retirement benefit that is not a life
         annuity. If the above condition is not met, the consent requirements of
         this Article shall be operative.

SECTION 6.04  -  NOTICE REQUIREMENTS.

(a)     Optional forms of retirement benefit. The Plan Administrator shall
        furnish to the Member and the Member's spouse a written explanation of
        the optional forms of retirement benefit in Section 6.02, including the
        material features and relative values of these options, in a manner that
        would satisfy the notice requirements of Code Section 417(a)(3) and the
        right of the Member and the Member's spouse to defer distribution until
        the benefit is no longer immediately distributable. The Plan
        Administrator shall furnish the written explanation by a method
        reasonably calculated to reach the attention of the Member and the
        Member's spouse no less than 30 days and no more than 90 days before the
        Annuity Starting Date.

(b)     Qualified Joint and Survivor Form. The Plan Administrator shall furnish
        to the Member a written explanation of the following: the terms and
        conditions of the Qualified Joint and Survivor Form; the Member's right
        to make, and the effect of, an election to waive the Qualified Joint and
        Survivor Form; the rights of the Member's spouse; and the right to
        revoke an election and the effect of such a revocation. The Plan
        Administrator shall furnish the written explanation by a method
        reasonably calculated to reach the attention of the Member no less than
        30 days and no more than 90 days before the Annuity Starting Date.

        After the written explanation is given, a Member or spouse may make
        written request for additional information. The written explanation must
        be personally delivered or mailed (first class mail, postage prepaid) to
        the Member or spouse within thirty days from the date


                                      -66-


ARTICLE VI

<PAGE>   67
         of the written request. The Plan Administrator does not need to comply
         with more than one such request by a Member or spouse.

        The Plan Administrator's explanation shall be written in nontechnical
        language and will explain the terms and conditions of the Qualified
        Joint and Survivor Form and the financial effect upon the Member's
        benefit (in terms of dollars per benefit payment) of electing not to
        have benefits distributed in accordance with the Qualified Joint and
        Survivor Form.

(c)     Qualified Preretirement Survivor Annuity. The Plan Administrator shall
        furnish to the Member a written explanation of the following: the terms
        and conditions of the Qualified Preretirement Survivor Annuity; the
        Member's right to make, and the effect of, an election to waive the
        Qualified Preretirement Survivor Annuity; the rights of the Member's
        spouse; and the right to revoke an election and the effect of such a
        revocation. The Plan Administrator shall furnish the written explanation
        by a method reasonably calculated to reach the attention of the Member
        within the applicable period. The applicable period for a Member is
        whichever of the following periods ends last:

         (1)      the period beginning one year before the date the individual
                  becomes a Member and ending one year after such date; or

        (2)     the period beginning one year before the date the Member's
                spouse is first entitled to a Qualified Preretirement Survivor
                Annuity and ending one year after such date.

        If such notice is given before the period beginning with the first day
        of the Plan Year in which the Member attains age 32 and ending with the
        close of the Plan Year preceding the Plan Year in which the Member
        attains age 35, an additional notice shall be given within such period.
        If a Member ceases to be an Employee before attaining age 35, an
        additional notice shall be given within the period beginning one year
        before the date he ceases to be an Employee and ending one year after
        such date.

        After the written explanation is given, a Member or spouse may make
        written request for additional information. The written explanation must
        be personally delivered or mailed (first class mail, postage prepaid) to
        the Member or spouse within thirty days from the date of the written
        request. The Plan Administrator does not need to comply with more than
        one such request by a Member or spouse.

        The Plan Administrator's explanation shall be written in nontechnical
        language and will explain the terms and conditions of the Qualified
        Preretirement Survivor Annuity and the financial effect upon the
        spouse's benefit (in terms of dollars per benefit payment) of electing
        not to have benefits distributed in accordance with the Qualified
        Preretirement Survivor Annuity.

SECTION 6.05  -  TRANSITIONAL RULES.

In modification of the preceding provisions of this Plan, distributions
(including distributions to a five-percent owner of us) may be made in a form
which would not have caused this Plan to be


                                      -67-


ARTICLE VI

<PAGE>   68
disqualified under Code Section 401(a)(9) as in effect before the TEFRA
Compliance Date. The form must be elected by the Member or, if the Member has
died, by the Beneficiary. The election must be made in writing and signed before
January 1, 1984. The election will only be applicable if the Member has an
Account as of December 31, 1983. The Member's or Beneficiary's election must
specify when the distribution is to begin, the form of distribution and the
Contingent Annuitant and/or Beneficiaries listed in the order of priority, if
applicable.

A distribution upon death will not be covered by this transitional rule unless
the election contains the required information described above with respect to
the distributions to be made when the Member dies. Distributions in the process
of payment on January 1, 1984, are deemed to meet the above requirements if the
form of distribution was elected in writing and the form met the requirements of
Code Section 401(a)(9) as in effect before the TEFRA Compliance Date. If the
election under this paragraph is revoked, any subsequent distribution must meet
the requirements of Code Section 401(a)(9) and the proposed regulations
thereunder. If an election is revoked subsequent to the date distributions are
required to begin, the Plan must distribute by the end of the calendar year
following the calendar year in which the revocation occurs the total amount not
yet distributed which would have been required to have been distributed to
satisfy Code Section 401(a)(9) and the proposed regulations thereunder, but for
the Code Section 242(b)(2) election. For calendar years beginning after December
31, 1988, such distribution must meet the minimum distribution incidental
benefit requirements in section 1.401(a)(9)-2 of the proposed regulations. Any
changes in the election will be considered a revocation of the election.
However, the mere substitution or addition of another Beneficiary (one not named
in the election) under the election will not be considered to be a revocation of
the election, so long as such substitution or addition does not alter the period
over which distributions are to be made under the election, directly or
indirectly (for example, by altering the relevant measuring life). In the case
in which an amount is transferred or rolled over from one plan to another plan,
the rules in Q&A J-2 and Q&A J-3 of section 1.401(a)(9)-l of the proposed
regulations shall apply. A Member's election of an optional form of retirement
benefit shall be subject to his spouse's consent as provided in Section 6.03.

A Member, who would not otherwise receive the benefits prescribed by the
previous sections of this article, will be entitled to the following benefits:

        (a)    If he is living and not receiving benefits on August 23, 1984, he
               will be given the opportunity to elect to have the prior sections
               of this article apply, if he is credited with at least one Hour
               of Service under this Plan or a predecessor plan in a plan year
               beginning on or after January 1, 1976, and he had at least ten
               Years of Service when he separated from service.

        (b)    If he is living and not receiving benefits on August 23, 1984, he
               will be given the opportunity to elect to have his benefits paid
               according to the following provisions of this section, if he is
               credited with at least one Hour of Service under this Plan or a
               predecessor plan on or after September 2, 1974, and he is not
               credited with any service in a plan year beginning on or after
               January 1, 1976.


                                      -68-


ARTICLE VI

<PAGE>   69
The respective opportunities to elect (as described in (a) and (b) above) must
be afforded to the appropriate Members during the period beginning on August 23,
1984, and ending on the date benefits would otherwise begin to such Member.

Any Member who has elected according to (b) above and any member who does not
elect under (a) above or who meets the requirements of (a) above except that
such Member does not have at least ten Years of Service when he separated from
service, shall have his benefits distributed in accordance with the following if
benefits would have been payable in the form of a life annuity:

(c) Automatic joint and survivor annuity. If benefits in the form of a life
annuity become payable to a married Member who:

         (1)      begins to receive payments under the Plan on or after Normal
                  Retirement Age; or

         (2)      dies on or after Normal Retirement Age while still working for
                  us; or

         (3)      begins to receive payments on or after the qualified early
                  retirement age; or

         (4)      separates from service on or after attaining Normal Retirement
                  Age (or the qualified early retirement age) and after
                  satisfying the eligibility requirements for the payment of
                  benefits under the Plan and thereafter dies before beginning
                  to receive such benefits;

         then such benefits will be paid under the Qualified Joint and Survivor
         Form, unless the Member has elected otherwise during the election
         period. The election period must begin at least six months before the
         Member attains qualified early retirement age and end not more than 90
         days before benefits begin. Any election hereunder will be in writing
         and may be changed by the Member at any time.

(d)     Election of early survivor annuity. A Member who is employed after
        attaining the qualified early retirement age will be given the
        opportunity to elect, during the election period, to have a Qualified
        Preretirement Survivor Annuity payable on death. Any election under this
        provision will be in writing and may be changed by the Member at any
        time. The election period begins on the later of (1) the 90th day before
        the Member attains the qualified early retirement age, or (2) the
        Member's Entry Date, and ends on the date the Member terminates
        employment.

(e) For purposes of this paragraph, qualified early retirement age is the latest
of:

         (1)      the earliest date, under the Plan, on which the Member may
                  elect to receive retirement benefits,

         (2)      the first day of the 120th month beginning before the Member
                  reaches Normal Retirement Age, or

         (3)      the Member's Entry Date.

ARTICLE VII
TERMINATION OF PLAN


We expect to continue the Plan indefinitely, but reserve the right to terminate
the Plan in whole or in part at any time upon giving written notice to all
parties concerned. Complete discontinuance of Contributions constitutes complete
termination of Plan.

The Account of each Member shall be fully (100%) vested and nonforfeitable as of
the effective date of complete termination of the Plan. The Account of each
Member who becomes an Inactive Member because he is no longer an Eligible
Employee due to partial termination of the Plan shall be fully (100%) vested and
nonforfeitable as of the effective date of the partial Plan termination. If a
Member ceased to be an Employee before partial termination of the Plan but
otherwise would have become an Inactive Member upon partial termination due to
no longer being an Eligible Employee, his Account shall be fully (100%) vested
and nonforfeitable as of the effective date of the partial termination of the
Plan. An Inactive Member's Vested Account shall continue to participate in the
earnings credited, expenses charged and any appreciation or depreciation of the
Investment Fund until the Vested Account is distributed. A distribution under
this article shall be a retirement benefit and shall be distributed to the
Member according to the provisions of Article VI.

A Member's Account which does not result from Contributions which are used to
compute the Actual Deferral Percentage, as defined in Section 3.07, may be
distributed to the Member after the effective date of the complete or partial
Plan termination. A Member's Account resulting from Contributions which are used
to compute such percentage (Elective Deferral Contributions, Qualified
Nonelective Contributions, and Qualified Matching Contributions) may be
distributed upon termination of the Plan without the establishment of another
defined contribution plan.

Upon complete termination of the Plan, no more Employees shall become Members
and no more Contributions shall be made.

The assets of this Plan shall not be paid to us at any time, except that, after
the satisfaction of all liabilities under the Plan, any assets remaining may be
paid to us. The payment may not be made if it would contravene any provision of
law.

ADMINISTRATION OF PLAN


SECTION 8.01 - ADMINISTRATION.

Subject to the provisions of this article, the Plan Administrator has complete
control of the administration of the Plan. The Plan Administrator has all the
powers necessary for it to properly carry out its administrative duties. Not in
limitation, but in amplification of the foregoing, the Plan Administrator has
the power to construe the Plan and to determine all questions that may arise
under the Plan, including all questions relating to the eligibility of Employees
to participate in the Plan and the amount of benefit to which any Member,
Beneficiary, spouse, or Contingent Annuitant may become entitled. The Plan
Administrator's decisions upon all matters within the scope of its authority are
final.

Unless otherwise set out in the Plan or Annuity Contract, the Plan Administrator
may delegate recordkeeping and other duties which are necessary to assist it
with the administration of the Plan to any person or firm which agrees to accept
such duties. The Plan Administrator shall be entitled to rely upon all tables,
valuations, certificates, and reports furnished by the consultant or actuary
appointed by the Plan Administrator and upon all opinions given by any counsel
selected or approved by the Plan Administrator.

The Plan Administrator shall receive all claims for benefits by Members, former
Members, Beneficiaries, spouses, and Contingent Annuitants. The Plan
Administrator shall determine all facts necessary to establish the right of any
Claimant to benefits and the amount of those benefits under the provisions of
the Plan. The Plan Administrator may establish rules and procedures to be
followed by Claimants in filing claims for benefits, in furnishing and verifying
proofs necessary to determine age, and in any other matters required to
administer the Plan.

SECTION 8.02 - RECORDS.

All acts and determinations of the Plan Administrator shall be duly recorded.
All these records, together with other documents necessary for the
administration of the Plan, shall be preserved in the Plan Administrator's
custody.

Writing (handwriting, typing, printing), photostating, photographing,
microfilming, magnetic impulse, mechanical or electrical recording, or other
forms of data compilation shall be acceptable means of keeping records.

SECTION 8.03  -  INFORMATION AVAILABLE.

Any Member in the Plan or any Beneficiary may examine copies of the Plan
description, latest annual report, any bargaining agreement, this Plan, the
contract, or any other instrument under which the Plan was established or is
operated. The Plan Administrator shall maintain all of the items listed in this
section in its office, or in such other place or places as it may designate in
order to comply with governmental regulations. These items may be examined
during


                                      -71-

ARTICLE VIII

<PAGE>   72
reasonable business hours. Upon the written request of a Member or Beneficiary
receiving benefits under the Plan, the Plan Administrator shall furnish him with
a copy of any of these items. The Plan Administrator may make a reasonable
charge to the requesting person for the copy.

SECTION 8.04  -  CLAIM AND APPEAL PROCEDURES.

A Claimant must submit any required forms and pertinent information when making
claim for benefits under the Plan.

If a claim for benefits under the Plan is denied, the Plan Administrator shall
provide adequate written notice to any Claimant whose claim for benefits under
the Plan has been denied. The notice must be furnished within ninety days of the
date that the claim is received by the Plan Administrator. The Claimant shall be
notified in writing within this initial ninety-day period if special
circumstances require an extension of time needed to process the claim and the
date by which the Plan Administrator's decision is expected to be rendered. The
written notice shall be furnished no later than 180 days after the date the
claim was received by the Plan Administrator.

The Plan Administrator's notice to the Claimant shall specify the reason for the
denial; specify references to pertinent Plan provisions on which denial is
based; describe any additional material and information needed for the Claimant
to perfect his claim for benefits; explain why the material and information is
needed; inform the Claimant that any appeal he wishes to make must be made in
writing to the Plan Administrator within sixty days after receipt of the Plan
Administrator's notice of denial of benefits and that failure to make the
written appeal within such sixty-day period renders the Plan Administrator's
determination of such denial final, binding and conclusive.

If the Claimant appeals to the Plan Administrator, the Claimant, or his
authorized representative, may submit in writing whatever issues and comments
the Claimant, or the representative, feels are pertinent. The Claimant, or the
authorized representative, may review pertinent Plan documents. The Plan
Administrator shall reexamine all facts related to the appeal and make a final
determination as to whether the denial of benefits is justified under the
circumstances. The Plan Administrator shall advise the Claimant of its decision
within sixty days of his written request for review, unless special
circumstances (such as a hearing) would make rendering a decision within the
sixty-day limit unfeasible. The Claimant shall be notified within the sixty-day
limit if an extension is necessary. The Plan Administrator shall render a
decision on a claim for benefits no later than 120 days after the request for
review is received.

SECTION 8.05 - UNCLAIMED VESTED ACCOUNT PROCEDURES.

If a Member or the Member's spouse or Beneficiary does not claim the Member's
Vested Account, the Vested Account may be forfeited and applied according to the
provisions of Section 3.04. An unclaimed Vested Account shall not be forfeited
until the latest of the date the Member attains age 62, attains Normal
Retirement Age, or six months after the date the Member, spouse, or Beneficiary
is notified, by certified or registered mail addressed to his last known
address, that he is entitled to a benefit. If by the latest date above, the
Member, spouse, or Beneficiary has not


                                      -72-


ARTICLE VIII

<PAGE>   73
claimed the Vested Account or made his whereabouts known in writing, the Plan
Administrator may treat the Vested Account as a Forfeiture.

If a Member's Vested Account is forfeited according to the provisions of the
above paragraph and the Member or the Member's spouse or Beneficiary at any time
makes a claim for benefits, the forfeited Vested Account shall be reinstated,
unadjusted for any gains or losses occurring after the date it was forfeited.
The reinstated Vested Account shall then be distributed to the Member, spouse,
or Beneficiary according to the preceding provisions of the Plan.

SECTION 8.06  -  DELEGATION OF AUTHORITY.

All or any part of the administrative duties and responsibilities under this
article may be delegated by the Plan Administrator to a retirement committee.
The duties and responsibilities of the retirement committee shall be set out in
a separate written agreement.

TRUST PROVISIONS


SECTION 8A.01  -  THE TRUST AND TRUST FUND.

If Item T(1) is selected, we have established this Trust by executing the
attached Adoption Agreement. The Trust is established for the purpose of holding
and distributing the Trust Fund under the provisions of the Plan. The Trust is
construed, regulated, and administered under the law of the state in which we
have our principal office.

The Trust Fund consists of the total funds held under the Trust for the purpose
of providing benefits for Members. These funds result from Contributions made
under the Plan, which are forwarded to the Trustee to be deposited in the Trust
Fund. The Trust Fund shall be valued at current fair market value as of the last
day of the last calendar month ending in the Plan Year and, at the discretion of
the Trustee, may be valued more frequently. The valuation shall take into
consideration investment earnings credited, expenses charged, payments made, and
changes in the values of the assets held in the Trust Fund. The Account of a
Member shall be credited with its share of the gains and losses of the Trust
Fund. That part of a Member's Account invested in a funding arrangement which
establishes an account or accounts for such Member thereunder shall be credited
with the gain or loss from such account or accounts. That part of a Member's
Account which is invested in other funding arrangements shall be credited with a
proportionate share of the gain or loss of such investments. The share shall be
determined by multiplying the gain or loss of the investment by the ratio of the
part of the Member's Account invested in such funding arrangement to the total
of the Trust Fund invested in such funding arrangement.

SECTION 8A.02  -  THE TRUSTEE.

We have appointed the Trustee named in Item T. We have the power to appoint an
additional or successor Trustee or remove a Trustee at any time by amending the
Adoption Agreement.

The Trustee accepts this appointment by executing the Adoption Agreement or an
amendment to it. A Trustee may resign at any time upon thirty days written
notice to us. If a Trustee is removed, resigns or dies, the successor Trustee
whom we appoint has the same powers and duties as the Trustee replaced. Pending
the appointment of and acceptance of the successor Trustee, a remaining Trustee
has full power to act. When appointment has been accepted by a successor
Trustee, the removed or resigning Trustee must assign, transfer, pay over, and
deliver to the successor Trustee all of the assets which then constitute the
Trust Fund.

If there are two or more persons appointed as Trustees, the Trustees may, in
writing, name one of their number to act in the execution of all documents
relating to the Plan and Trust. When more than two persons have been appointed
as Trustee, all acts and decisions shall be made by majority vote.

SECTION 8A.03  -  DUTIES OF TRUSTEE.


                                      -74-


ARTICLE VIIIA

<PAGE>   75
It is the duty of the Trustee to accept and hold the Trust Fund and administer
it according to the provisions of the Trust. The Trustee has no duty to demand
or require that Contributions be made to the Trust, nor shall a Trustee be
liable to determine the amount of any Contributions to the Trust.

The Plan is administered by the Plan Administrator. The Trustee is not
responsible for any aspect of its administration. The Trustee is not required to
look into any action taken by the Named Fiduciary, Plan Administrator, or us and
will be fully protected in taking, permitting or omitting any action on the
basis of our actions. Any action by the Named Fiduciary, Plan Administrator, or
us according to the Plan provisions shall be evidenced in writing. We will
indemnify the Trustee by satisfying any liabilities the Trustee may incur in
acting in accordance with the Trust provisions upon written instruction from the
Named Fiduciary, Plan Administrator, or us.

SECTION 8A.04  -  POWERS OF TRUSTEE.

Except where the Plan expressly provides that the Trustee is subject to the
direction of the Named Fiduciary, Plan Administrator, or us, the Trustee is
authorized and empowered

(a)      to apply for and invest all or any part of the assets of the Trust Fund
         in the Annuity Contract, an Insurance Policy, or both, issued by the
         Insurer and to hold the Annuity Contract and any Insurance Policy as
         owner;

(b)      to invest and reinvest all or any part of the assets of the Trust Fund
         in any bonds, debentures, notes, mortgages or mortgage participations,
         preferred stocks, common stocks or other securities, or other real or
         personal properties;

(c)      to sell, exchange, convey, transfer, or otherwise dispose of any
         property held by it, by private contract or at public auction;

(d)      to exercise the voting rights of any stocks, bonds or other securities
         and to exercise any of the powers of an owner with respect to stocks,
         bonds, securities, or other property held in the Trust Fund;

(e)      to retain in cash an amount which the Trustee considers advisable, and
         to deposit cash in any depository selected by it, without liability for
         interest;

(f)      to make, execute, acknowledge, and deliver any instruments necessary to
         carry out the powers granted it;

(g)      to employ such agents, actuaries, clerical help, custodians, and others
         as are needed to carry out the Trustee's duties;

(h)      to consult with legal counsel, including our counsel, with respect to
         the meaning or construction of, or the Trustee's obligations or duties
         under, the Plan and Trust, or with


                                      -75-


ARTICLE VIIIA

<PAGE>   76
         respect to any action or proceeding or any question of law. The Trustee
         shall be fully protected with respect to any action it takes in good
         faith pursuant to the advice of such counsel.

(i)      to enforce any right, obligation, or claim and, in its absolute
         discretion, to protect in any way the interest of the Trust Fund and if
         the Trustee considers such an action to be in the best interest of the
         Trust Fund, to abstain from the enforcement of any right, obligation,
         or claim and to abandon any property it has held.

SECTION 8A.05 - EXPENSES.

We pay the expenses incurred by the Trustee in the performance of its duties,
any fees for legal services rendered to the Trustee, and compensation to the
Trustee which we have mutually agreed upon in writing. The Trustee may charge
against the Trust Fund taxes imposed with respect to the Trust Fund or its
income.

SECTION 8A.06 - ACCOUNTING.

The Trustee shall maintain accurate and detailed records on all receipts,
investments, disbursements, and other transactions performed in its capacity as
Trustee. These records must be open to inspection and audit by the Plan
Administrator, Named Fiduciary, and us at all reasonable times.

Writing (handwriting, typing, printing), photostating, photographing,
microfilming, magnetic impulse, mechanical or electrical recording, or other
forms of data compilation shall be acceptable means of keeping records.

The Trustee shall file all reports, returns, and information required under the
Code and regulations and rulings issued under the Code.

The Trustee shall file with us an accounting of its transactions as soon as
practical after each Yearly Date or any other date we may specify. Any report or
accounting which the Trustee files with us is open to inspection by a Member for
a period of sixty days following the date it is filed. At the end of the
sixty-day period, the Trustee is released and discharged as to any matters set
forth in the report or account, except with respect to any act or omission as to
which a Member, the Plan Administrator, the Named Fiduciary or we have filed a
written objection within the sixty-day period.

GENERAL PROVISIONS


SECTION 9.01 - AMENDMENTS.

We may amend a selection or specification in the Adoption Agreement at any time,
including any remedial retroactive changes (within the time specified by
Internal Revenue Service regulation) to comply with any law or regulation issued
by any governmental agency to which the Plan is subject. An amendment may not
diminish or adversely affect any accrued interest or benefit of Members or their
Beneficiaries or eliminate an optional form of distribution with respect to
benefits attributable to service before the amendment nor allow reversion or
diversion of Plan assets to us at any time, except as may be required to comply
with any law or regulation issued by any governmental agency to which the Plan
is subject. No amendment to this Plan shall be effective to the extent that it
has the effect of decreasing a Member's accrued benefit. However, a Member's
Account may be reduced to the extent permitted under Code Section 412(c)(8). For
purposes of this paragraph, a Plan amendment which has the effect of decreasing
a Member's Account or eliminating an optional form of benefit, with respect to
benefits attributable to service before the amendment shall be treated as
reducing an accrued benefit. Furthermore, if the vesting schedule of the Plan is
amended, in the case of an Employee who is a Member as of the later of the date
such amendment is adopted or the date it becomes effective, the nonforfeitable
percentage (determined as of such date) of such Employee's right to his
employer-derived accrued benefit will not be less than his percentage computed
under the Plan without regard to such amendment. We may amend the Plan by adding
overriding plan language to the Adoption Agreement in order to satisfy Code
Sections 415 and 416 because of the required aggregation of multiple plans under
those sections. We may amend the Plan by adding certain model amendments
published by the Internal Revenue Service which specifically provide that their
adoption will not cause the Plan to be treated as individually designed. An
amendment to this Plan will be forwarded to Principal Mutual Life Insurance
Company, the prototype plan sponsor.

If we amend the Plan for any reason other than those set out above or if the
Plan loses its qualified status, the Plan shall not be a prototype plan within
the meaning of governmental regulations. In that event, Principal Mutual Life
Insurance Company will not be the prototype plan sponsor and the Plan will not
be a prototype plan. As the Employer, we reserve the right to continue our
retirement program under a document separate and distinct from this Plan. In
such event, all rights and obligations of any Member, Beneficiary, or of ours
under this document shall cease. Assets held in support of this Plan will be
transferred to the designated funding medium under the new or restated plan and,
if applicable, trust, in the manner permitted under, and subject to the
provisions of, the Annuity Contract.

We delegate authority to amend this Plan to Principal Mutual Life Insurance
Company as sponsor. We hereby consent to any such amendment. However, no such
amendment shall increase the duties of the Named Fiduciary without his consent.
Such an amendment shall not deprive any Member or Beneficiary of any accrued
benefit except to the extent necessary to comply with any law or regulation
issued by any governmental agency to which this Plan is


                                      -77-


ARTICLE IX

<PAGE>   78
subject. Such an amendment shall not provide that the Investment Fund be used
for any purpose other than the exclusive benefit of Members or their
Beneficiaries or that the Investment Fund ever revert to or be used by us.

Any amendment to this Plan by Principal Mutual Life Insurance Company, as
sponsor, shall be deemed to be an amendment to this Plan by us. The effective
date of any amendment shall be specified in the written instrument of amendment.

An amendment shall not decrease a Member's vested interest in the Plan. If an
amendment to the Plan, or a deemed amendment in the case of a change in
top-heavy status of the Plan as provided in Section 10.03, changes the
computation of Vesting Percentage (whether directly or indirectly), each Member
or former Member

(a)      who has completed at least three Years of Service with us on the date
         the election period described below ends (five Years of Service if the
         Member does not have at least one Hour of Service in a Plan Year
         beginning after December 31, 1988) and

(b)      whose Vesting Percentage will be determined on any date after the date
         of the change

may elect, during the election period, to have the nonforfeitable percentage of
his Account which results from our Contributions determined without regard to
the amendment. This election may not be revoked. If after the Plan is changed
the Member's Vesting Percentage will at all times be as great as it would have
been if the change had not been made, no election needs to be provided. The
election period shall begin no later than the date the Plan amendment is
adopted, or deemed adopted in the case of a change in the top-heavy status of
the Plan, and end no earlier than the sixtieth day after the latest of the date
the amendment is adopted (deemed adopted) or becomes effective, or the date the
Member is issued written notice of the amendment (deemed amendment) by us or the
Plan Administrator.

SECTION 9.02  -  MERGERS AND DIRECT TRANSFERS.

The Plan may not be merged or consolidated with, nor have its assets or
liabilities transferred to, any other retirement plan, unless each Member in the
plan would (if the plan then terminated) receive a benefit immediately after the
merger, consolidation or transfer which is equal to or greater than the benefit
the Member would have been entitled to receive immediately before the merger,
consolidation or transfer (if this Plan had then terminated). We may enter into
merger agreements or direct transfer of assets agreements with the employers
under other retirement plans which are qualifiable under Code Section 401(a),
including an elective transfer, and may accept the direct transfer of plan
assets, or may transfer plan assets, as a party to any such agreement. We shall
not consent to, or be a party to a merger, consolidation or transfer of assets
with a defined benefit plan if such action would result in a defined benefit
feature being maintained under this Plan.

The Plan may accept a direct transfer of plan assets on behalf of an Eligible
Employee. If the Eligible Employee is not an Active Member when the transfer is
made, the Eligible Employee shall be deemed to be an Active Member only for the
purpose of investment and distribution of


ARTICLE IX                            -78-
<PAGE>   79
the transferred assets. Our Contributions shall not be made for or allocated to
the Eligible Employee and he may not make Member Contributions, until the time
he meets all of the requirements to become an Active Member.

The Plan shall hold, administer and distribute the transferred assets as a part
of the Plan. The Plan shall maintain a separate account for the benefit of the
Employee on whose behalf the Plan accepted the transfer in order to reflect the
value of the transferred assets. Unless a transfer of assets to the Plan is an
elective transfer, the Plan shall apply the optional forms of benefit
protections described in Section 9.01 to all transferred assets. A transfer is
elective if: (1) the transfer is voluntary, under a fully informed election by
the Member; (2) the Member has an alternative that retains his Code Section
411(d)(6) protected benefits (including an option to leave his benefit in the
transferor plan, if that plan is not terminating); (3) if the transferor plan is
subject to Code Sections 401(a)(11) and 417, the transfer satisfies the
applicable spousal consent requirements of the Code; (4) the notice requirements
under Code Section 417, requiring a written explanation with respect to an
election not to receive benefits in the form of a qualified joint and survivor
annuity, are met with respect to the Member and spousal transfer election; (5)
the Member has a right to immediate distribution from the transferor plan under
provisions in the plan not inconsistent with Code Section 401(a); (6) the
transferred benefit is equal to the Member's entire nonforfeitable accrued
benefit under the transferor plan, calculated to be at least the greater of the
single sum distribution provided by the transferor plan (if any) or the present
value of the Member's accrued benefit under the transferor plan payable at the
plan's normal retirement age and calculated using an interest rate subject to
the restrictions of Code Section 417(e) and subject to the overall limitations
of Code Section 415; (7) the Member has a 100% nonforfeitable interest in the
transferred benefit; and (8) the transfer otherwise satisfies applicable
Treasury regulations.

SECTION 9.03  -  PROVISIONS RELATING TO THE INSURER AND OTHER PARTIES.

The obligations of an Insurer shall be governed solely by the provisions of the
Annuity Contract or Insurance Policy. The Insurer shall not be required to
perform any act not provided in or contrary to the provisions of the Annuity
Contract or Insurance Policy.
See Section 9.09.

Any issuer or distributor of investment contracts or securities is governed
solely by the terms of its policies, written investment contract, prospectuses,
security instruments, and any other written agreements entered into with the
Trustee.

Such Insurer, issuer, or distributor is not a party to the Plan, nor bound in
any way by the Plan provisions. Such parties shall not be required to look to
the terms of this Plan, nor to determine whether we, the Plan Administrator, the
Trustee, or the Named Fiduciary have the authority to act in any particular
manner or to make any contract or agreement.

Until notice of any amendment or termination of this Plan or of a change in
Trustee has been received by the Insurer at its home office or an issuer or
distributor at their principal address, they are and shall be fully protected in
assuming that the Plan has not been amended or terminated and in dealing with
any party acting as Trustee according to the latest information which they have
received at their home office or principal address.


ARTICLE IX                            -79-
<PAGE>   80
SECTION 9.04  -  EMPLOYMENT STATUS.

Nothing contained in this Plan gives any Employee the right to be retained in
our employ or to interfere with our right to discharge any Employee.

SECTION 9.05  -  RIGHTS TO PLAN ASSETS.

An Employee shall not have any right to or interest in any assets of the Plan
upon termination of employment or otherwise except as specifically provided
under this Plan, and then only to the extent of the benefits payable to such
Employee according to the Plan provisions.

Any final payment or distribution to a Member or his legal representative or to
any Beneficiaries, spouse, or Contingent Annuitant of such Member under the Plan
provisions shall be in full satisfaction of all claims against the Plan, the
Named Fiduciary, the Plan Administrator, the Insurer, the Trustee, and us
arising under or by virtue of the Plan.

SECTION 9.06 - BENEFICIARY.

Each Member may name a Beneficiary to receive any death benefit (other than any
income payable to a Contingent Annuitant) which may arise out of his membership
in the Plan. The Member may change his Beneficiary from time to time. Unless a
qualified election has been made, for purposes of distributing any death
benefits before Retirement Date, the Beneficiary of a Member who has a spouse
who is entitled to a Qualified Preretirement Survivor Annuity shall be the
Member's spouse. The Member's Beneficiary designation and any change of
Beneficiary shall be subject to the provisions of Section 6.03. It is the
responsibility of the Member to give written notice to the Insurer of the name
of the Beneficiary on a form furnished for that purpose.

With our consent, the Plan Administrator may maintain records of Beneficiary
designations for Members before their Retirement Dates. In that event, the
written designations made by Members shall be filed with the Plan Administrator.
If a Member dies before his Retirement Date, the Plan Administrator shall
certify to the Insurer the Beneficiary designation on its records for the
Member.

If there is no Beneficiary named or surviving when a Member dies, any death
benefit under the Annuity Contract or Insurance Policy will be paid according to
the provisions of the respective documents.

SECTION 9.07  -  NONALIENATION OF BENEFITS.

Benefits payable under the Plan are not subject to the claims of any creditor of
any Member, Beneficiary, spouse, or Contingent Annuitant. A Member, Beneficiary,
spouse, or Contingent Annuitant does not have any rights to alienate,
anticipate, commute, pledge, encumber or assign such benefits except in the case
of a Trustee approved loan as provided in Section 5.06. The preceding sentences
shall also apply to the creation, assignment, or recognition of a right to any
benefit payable with respect to a Member according to a domestic relations
order, unless such


ARTICLE IX                            -80-
<PAGE>   81
order is determined by the Plan Administrator to be a qualified domestic
relations order, as defined in Code Section 414(p), or any domestic relations
order entered before January 1, 1985.

SECTION 9.08  -  FACILITY OF PAYMENT.

If any Member, Beneficiary, spouse, or Contingent Annuitant is physically or
mentally incapable of giving a valid receipt for any payment due him and a legal
representative has not been appointed for such person, the Plan Administrator
may direct the Insurer to make such payment to any person or institution
maintaining such Member, Beneficiary, spouse, or Contingent Annuitant. The
payment to such person or institution shall be a valid and complete discharge of
any liability for the making of such payment under the provisions of the Plan.

SECTION 9.09 - CONSTRUCTION.

The validity of the Plan or any of its provisions is determined under and
construed according to Federal law and, to the extent permissible, according to
the laws of the state in which we have our principal office. In case any
provision of this Plan is held illegal or invalid for any reason, such
determination shall not affect the remaining provisions of this Plan, and the
Plan shall be construed and enforced as if the illegal or invalid provision had
never been included.

In the event of any conflict between the provisions of the Plan and the terms of
any contract or policy issued hereunder, the provisions of the Plan control.

SECTION 9.10  -  LEGAL ACTIONS.

The Plan, the Plan Administrator, the Trustee and the Named Fiduciary are the
necessary parties to any action or proceeding involving the assets held with
respect to the Plan or administration of the Plan or Trust. No person employed
by us, no Member, former Member, or their Beneficiaries or any other person
having or claiming to have an interest in the Plan is entitled to any notice of
process. A final judgment entered in any such action or proceeding shall be
binding and conclusive on all persons having or claiming to have an interest in
the Plan.

SECTION 9.11 - SMALL AMOUNTS.

If the Vested Account of a Member has never exceeded $3,500, the entire Vested
Account shall be payable in a single sum as of the earliest of his Retirement
Date, the date he dies, or the date he ceases to be an Employee for any other
reason. If Item X(3)(b) of the Adoption Agreement - Plus is selected, the Member
shall not be treated as having ceased to be an Employee for any reason other
than retirement or death before the period of time elected in Item X(3)(b) has
elapsed and no small amount payment shall be made if he again becomes an
Employee before such period of time has elapsed. This is a small amounts
payment. If a small amount is payable as of the date the Member dies, the small
amounts payment shall be made to the Member's Beneficiary (spouse if the death
benefit is payable to the spouse). If a small amount is payable while the Member
is living, the small amounts payment shall be made to the Member. The small
amounts payment is in full settlement of all benefits otherwise payable.


ARTICLE IX                            -81-
<PAGE>   82
Before the first Yearly Date in 1989, the Member's Vested Account which results
from deductible Voluntary Contributions shall not be taken into account in
determining whether his Vested Account has exceeded $3,500.
No other small amounts payment shall be made.

SECTION 9.12  -  WORD USAGE.

The masculine gender, where used in this Plan, shall include the feminine gender
and singular words as used in this Plan may include the plural, unless the
context indicates otherwise.

SECTION 9.13  -  TRANSFERS BETWEEN PLANS.

If an Employee has been a member of another plan of ours which credited service
under the elapsed time method for any purpose which under this Plan is
determined using the hours method, then the Employee's service shall be equal to
the sum of (a), (b) and (c) below:

(a)      The number of whole years of service credited to the Employee under the
         other plan as of the date he became an Eligible Employee under this
         Plan.

(b)      One year of service for the applicable service period in which he
         became an Eligible Employee if he is credited with the required number
         of Hours of Service. If we do not have sufficient records to determine
         the Employee's actual Hours of Service in that part of the service
         period before the date he became an Eligible Employee, the Hours of
         Service shall be determined using an equivalency. For any month in
         which he would be required to be credited with one Hour of Service, the
         Employee shall be deemed for purposes of this section to be credited
         with 190 Hours of Service.

(c)      The Employee's service determined under this Plan using the hours
         method after the end of the service period in which he became an
         Eligible Employee.

If an Employee has been a member of another plan of ours which credited service
under the hours method for any purpose which under this Plan is determined using
the elapsed time method, then the Employee's service shall be equal to the sum
of (d), (e) and (f) below:

(d)      The number of whole years of service credited to the Employee under the
         other plan as of the beginning of the service period under that plan in
         which he became an Eligible Employee under this Plan.

(e)      The greater of (1) the service that would be credited to the Employee
         for that entire service period using the elapsed time method or (2) the
         service credited to him under the other plan as of the date he became
         an Eligible Employee under this Plan.

(f)      The Employee's service determined under this Plan using the elapsed
         time method after the end of the applicable service period under the
         other plan in which he became an Eligible Employee.


ARTICLE IX                            -82-
<PAGE>   83
Any modification of service contained in this Plan shall be applicable to the
service determined pursuant to this section.

If an Employee used to be a member of a Controlled Group member's plan which
credited service under a different method than is used in this Plan, in order to
determine entry and vesting, the provisions above shall apply as though the
Controlled Group member's plan were our plan. If the method of crediting service
under this Plan is changed, the service credited to an Employee shall be equal
to the service that would be credited to him under the above provisions as
though the Plan as in effect before the change were another plan of ours.

SECTION 9.14  -  PARTNERSHIP OR SOLE PROPRIETORSHIP.

(a)      For the purpose of applying the provisions of this Plan as to any Plan
         Year in which we are a partnership or sole proprietorship, the
         following terms are defined:

         Control(s) means, with regard to a trade or business, one
         owner-employee owns or a group of owner-employees together own (1) the
         entire interest in such trade or business or (2) in the case of a
         partnership, more than fifty percent of either the capital interest or
         the profits interest in the partnership. An owner-employee, or a group
         of owner-employees, shall be treated as owning any interest in a
         partnership which is owned, directly or indirectly, by a partnership
         which such owner-employee, or group of owner-employees, are considered
         to control within the meaning of the preceding sentence.

         Earned Income means, for a Self-Employed Individual, net earnings from
         self-employment in the trade or business for which this Plan is
         established if such Self-Employed Individual's personal services are a
         material income producing factor for that trade or business. Earned
         Income shall be determined without regard to items not included in
         gross income and the deductions properly allocable to or chargeable
         against such items. After the TEFRA Compliance Date, Earned Income
         shall be reduced for our employer contributions to our qualified
         retirement plan(s) to the extent deductible under Code Section 404.

         Net earnings shall be determined with regard to the deduction allowed
         to us by Code Section 164(f) for taxable years beginning after December
         31, 1989.

         In applying the provisions of this Plan, the Self-Employed Individual's
         Earned Income shall be deemed to be his Pay. For purposes of Section
         3.06, Earned Income shall include earned income within the meaning of
         Code Section 911 from sources outside the United States and shall be
         deemed to be his Compensation.

         Owner-Employee means a Self-Employed Individual who, in the case of a
         sole proprietorship, owns the entire interest in the unincorporated
         trade or business for which this Plan is established. If this Plan is
         established for a partnership, an Owner-Employee means a Self-Employed
         Individual who owns more than ten percent of either the capital
         interest or profits interest in such partnership.


ARTICLE IX                         -83-
<PAGE>   84
         In applying the provisions of this Plan, an Owner-Employee shall be
         deemed to be an Employee.

         Self-Employed Individual means, with respect to any Fiscal Year, an
         individual who has Earned Income for the Fiscal Year (or who would have
         Earned Income but for the fact the trade or business for which this
         Plan is established did not have net profits for such Fiscal Year).

         In applying the provisions of this Plan, a Self-Employed Individual
         shall be deemed to be an Employee.

(b)      If contributions are made for or allocated to or benefits accrue to an
         Owner-Employee who Controls, or a group of Owner-Employees who together
         Control, both the trade or business for which this Plan is established
         and one or more other trades or businesses, then this Plan and the
         plans established for such other trade(s) or business(es) must, if they
         were combined as a single plan, satisfy the requirements of Code
         Sections 401(a) and 401(d) and regulations thereunder.

         If this Plan provides Contributions for an Owner-Employee who Controls,
         or a group of Owner-Employees who Control, one or more other trades or
         businesses, the employees of each such other trade or business must be
         included in a plan which satisfies Code Sections 401(a) and 401(d) and
         regulations thereunder. Each such plan must provide contributions and
         benefits which are not less favorable than the Contributions and
         benefits provided for the Owner-Employee(s) under this Plan.

         If an Owner-Employee is covered under another qualifiable retirement
         plan as an owner-employee of a trade or business he does not Control,
         then the plan(s) of the trade(s) or business(es) the Owner-Employee
         does Control (including this Plan, if applicable) must provide
         contributions or benefits as favorable as those provided under the most
         favorable plan of the trade or business the Owner-Employee does not
         Control.

SECTION 9.15  -  QUALIFICATION OF PLAN.

If the Plan is denied initial qualification, it will terminate. We shall give
written notice to the Insurer and Trustee of the denial in sufficient time so
the assets resulting from Contributions which were conditioned on initial
qualification of the Plan may be returned within one year after the date of
denial. The Insurer will be notified that the Annuity Contract is to be
terminated and any Insurance Policy surrendered. The Plan assets which result
from Employer Contributions and Member Contributions shall be returned to us and
the Members, respectively. The Trustee, the Plan Administrator, and the Named
Fiduciary shall then be discharged from all obligations under the Plan and Trust
and the Insurer shall be discharged from all obligations under the Annuity
Contract and any Insurance Policy. A Member or Beneficiary shall not have any
right or claim to the assets or to any benefit under this Plan before the
Internal Revenue Service determines that the Plan and Trust qualify under the
provisions of Section 401(a) of the Code.


ARTICLE IX                            -84-
<PAGE>   85
If the Plan loses its qualified status, it shall no longer be a prototype plan
within the meaning of governmental regulations. In that event, Principal Mutual
Life Insurance Company will no longer be the Plan sponsor. We agree to give

ARTICLE X
TOP-HEAVY PLAN REQUIREMENTS


SECTION 10.01 - APPLICATION.

The provisions of this Article X shall supersede all other provisions in the
Plan to the contrary.

For the purpose of applying the Top-heavy Plan requirements of this article, all
members of the Controlled Group shall be treated as one Employer. The terms we,
us, and our as they are used in this article shall be deemed to include all
members of the Controlled Group unless the terms as used clearly indicate only
the Employer is meant.

The accrued benefit or account of a member which results from deductible
voluntary contributions shall not be included for any purpose under this
article.

The minimum vesting and contribution provisions of Sections 10.03 and 10.04
shall not apply to any Employee who is included in a group of Employees covered
by a collective bargaining agreement which the Secretary of Labor finds to be a
collective bargaining agreement between employee representatives and one or more
employers, including us, if there is evidence that retirement benefits were the
subject of good faith bargaining between such representatives. For this purpose,
the term "employee representatives" does not include any organization more than
half of whose members are employees who are owners, officers or executives.

SECTION 10.02 - DEFINITIONS.

The following terms are defined for purposes of this article.

AGGREGATION GROUP means

(a)      each of our retirement plans in which a Key Employee is a member during
         the Year containing the Determination Date or one of the four preceding
         Years.

(b)      each of our other retirement plans which allows the plan(s) described
         in (a) above to meet the nondiscrimination requirement of Code Section
         401(a)(4) or the minimum coverage requirement of Code Section 410, and

(c)      any of our other retirement plans not included in (a) or (b) above
         which we desire to include as part of the Aggregation Group. Such a
         retirement plan shall be included only if the Aggregation Group would
         continue to satisfy the requirements of Code Section 401(a)(4) and Code
         Section 410.

The plans in (a) and (b) above constitute the "required" Aggregation Group. The
plans in (a), (b) and (c) above constitute the "permissive" Aggregation Group.

COMPENSATION means, as to an Employee for any period, compensation as defined in
Code Section 415(c)(3), but including amounts contributed by us pursuant to a
salary reduction


ARTICLE X                             -86-
<PAGE>   87
agreement which are excludible from the Employee's gross income under Code
Sections 125, 402(a)(8), 402(h) or 403(b).

DETERMINATION DATE means as to this Plan, for any Year, the last day of the
preceding Year. However, if there is no preceding Year, the Determination Date
is the last day of such Year.

KEY EMPLOYEE means any Employee or former Employee (including Beneficiaries of
deceased Employees) who at any time during the determination period was

(a)      one of our officers (subject to the maximum below) whose Compensation
         (as defined in this section) for the Year exceeds 50 percent of the
         dollar limitation under Code Section 415(b)(1)(A),

(b)     one of the ten Employees who owns (or is considered to own, under Code
        Section 318) more than a half percent ownership interest and one of the
        largest interests in us during any Year of the determination period if
        such person's Compensation (as defined in this section) for the Year
        exceeds the dollar limitation under Code Section 415(c)(1)(A),

(c)      a five-percent owner of us, or

(d)      a one-percent owner of us whose Compensation (as defined in this
         section) for the Year is more than $150,000.

Each member of the Controlled Group shall be treated as a separate employer for
purposes of determining ownership in us.

The determination period is the Year containing the Determination Date and the
four preceding Years. If we have fewer than 30 Employees, no more than three
Employees shall be treated as Key Employees because they are officers. If we
have between 30 and 500 Employees, no more than ten percent of our Employees (if
not an integer, increased to the next integer) shall be treated as Key Employees
because they are officers. In no event will more than 50 Employees be treated as
Key Employees because they are officers if we have 500 or more Employees. The
number of Employees for any Plan Year is the greatest number of Employees during
the determination period. Officers who are employees described in Code Section
414(q)(8) shall be excluded. If we have more than the maximum number of officers
to be treated as Key Employees, the officers shall be ranked by the amount of
annual Compensation (as defined in this section), and those with the greater
amount of annual Compensation during the determination period shall be treated
as Key Employees. To determine the ten Employees owning the largest interests in
us, if more than one Employee has the same ownership interest, the Employee(s)
having the greater annual Compensation shall be treated as owning the larger
interests). The determination of who is a Key Employee shall be made according
to Code Section 416(i)(1) and the regulations thereunder.

NON-KEY EMPLOYEE means a person who is a non-key employee within the meaning of
Code Section 416 and regulations thereunder.


ARTICLE X                           -87-
<PAGE>   88
PRESENT VALUE means the present value of a member's accrued benefit under a
defined benefit plan as of his normal retirement age (attained age if later) or,
if the plan provides non-proportional subsidies, the age at which the benefit is
most valuable. The accrued benefit of any Employee (other than a Key Employee)
shall be determined under the method which is used for accrual purposes for all
our plans or if there is no one method which is used for accrual purposes for
all our plans, as if such benefit accrued not more rapidly than the slowest
accrual rate permitted under Code Section 411(b)(1)(C). The Present Value shall
be based only on the interest and mortality rates specified in the Adoption
Agreement. If the Present Value of accrued benefits is determined for a member
under more than one defined benefit plan included in the Aggregation Group, all
such plans shall use the same actuarial assumptions to determine the Present
Value.

TOP-HEAVY PLAN means a plan which is a top-heavy plan for any plan year
beginning after December 31, 1983. This Plan shall be a Top-heavy Plan if

(a)      the Top-heavy Ratio for this Plan alone exceeds sixty percent and this
         Plan is not part of any required Aggregation Group or permissive
         Aggregation Group.

(b)      this Plan is a part of a required Aggregation Group, but not part of a
         permissive Aggregation Group, and the Top-heavy Ratio for the required
         Aggregation Group exceeds sixty percent.

(c)      this Plan is a part of a required Aggregation Group and part of a
         permissive Aggregation Group and the Top-heavy Ratio for the permissive
         Aggregation Group exceeds sixty percent.

TOP-HEAVY RATIO means the ratio calculated below for this Plan or for the
Aggregation Group.

(a)     The Top-heavy Ratio for this Plan or for the Aggregation Group
        (including any simplified employee pension plan) if the Aggregation
        Group does not contain a defined benefit plan during the five-year
        period ending on the determination date which has or has had accrued
        benefits, is a fraction, the numerator of which is the sum of the
        account balances of all Key Employees as of the determination date and
        the denominator of which is the sum of all account balances of all
        employees as of the determination date. Both the numerator and
        denominator of the Top-heavy Ratio are adjusted for any distribution of
        an account balance made in the five-year period ending on the
        determination date in accordance with Code Section 416 and the
        regulations thereunder.

(b)      The Top-heavy Ratio for the Aggregation Group (including any simplified
         employee pension plan) if the Aggregation Group contains a defined
         benefit plan during the five-year period ending on the determination
         date which has or has had accrued benefits, is a fraction, the
         numerator of which is the sum of the account balances under the defined
         contribution plan(s) of all Key Employees and the Present Value of
         accrued benefits under the defined benefit plan(s) for all Key
         Employees, and the denominator of which is the sum of the account
         balances under the defined contribution plan(s) for all employees and
         the Present Value of accrued benefits under the defined benefit plans
         for all employees.


ARTICLE X                             -88-
<PAGE>   89
         Both the numerator and denominator of the Top-heavy Ratio are adjusted
         for any distribution of an account balance or an accrued benefit
         (including those made from terminated plan(s) of ours which would have
         been part of the required Aggregation Group had such plan(s) not been
         terminated) made in the five-year period ending on the determination
         date in accordance with Code Section 416 and the regulations
         thereunder.

(c)      For purposes of (a) and (b) above, the value of account balances and
         the Present Value of accrued benefits will be determined as of the most
         recent valuation date that falls within or ends with the 12-month
         period ending on the determination date, except as provided in Code
         Section 416 and the regulations thereunder for the first and second
         plan years of a defined benefit plan. The account balances and accrued
         benefits of an employee who is not a Key Employee but who was a Key
         Employee in a prior year will be disregarded. The calculation of the
         Top-heavy Ratio and the extent to which distributions, rollovers and
         transfers during the five-year period ending on the determination date
         are to be taken into account, shall be determined according to the
         provisions of Code Section 416 and regulations thereunder. The account
         balances and accrued benefits of an individual who has performed no
         service for us during the five-year period ending on the determination
         date shall be excluded from the Top-heavy Ratio until the time the
         individual again performs service for us. Deductible employee
         contributions will not be taken into account for purposes of computing
         the Top-heavy Ratio. When aggregating plans, the value of account
         balances and accrued benefits will be calculated with reference to the
         determination dates that fall within the same calendar year.

Account, as used in this definition, means the value of an employee's account
under one of our retirement plans on the latest valuation date. In the case of a
money purchase plan or target benefit plan, such value shall be adjusted to
include any contributions made for or by the employee after the valuation date
and on or before such determination date or due to be made as of such
determination date but not yet forwarded to the insurer or trustee. In the case
of a profit sharing plan, such value shall be adjusted to include any
contributions made for or by the employee after the valuation date and on or
before such determination date. During the first Year of any profit sharing plan
such adjustment in value shall include contributions made after such
determination date that are allocated as of a date in such Year. The
nondeductible voluntary contributions which an employee makes under a defined
benefit plan of ours shall be treated as if they were contributions under a
separate defined contribution plan.

VALUATION DATE means, as to this Plan, the last day of the last calendar month
ending in a Year.

YEAR means the Plan Year unless another year is specified by us in a separate
written resolution in accordance with regulations issued by the Secretary of the
Treasury or his delegate.

SECTION 10.03  -  MODIFICATION OF VESTING REQUIREMENTS.

If a Member's Vesting Percentage determined under the vesting schedule selected
in Item V is not as great as the Vesting Percentage would be if it were
determined under a schedule permitted in Code Section 416, the following shall
apply. During any Year in which the Plan is a Top-heavy Plan, the Member's
Vesting Percentage shall be the greater of the Vesting Percentage determined
under the schedule selected in Item U or,

(a) if the vesting schedule provides for partial vesting between 0% and 100%,
the schedule below.

The applicable schedule above shall not apply to Members who are not credited
with an Hour of Service after the Plan first becomes a Top-heavy Plan. The
Vesting Percentage determined above applies to all of the Member's Account
resulting from our Contributions, including Contributions we make before the
TEFRA Compliance Date or when this Plan is not a Top-heavy Plan.

If, in a later Year, this Plan is not a Top-heavy Plan, a Member's Vesting
Percentage shall be determined according to the provisions of Item U. A Member's
Vesting Percentage determined under either Item U or the schedule above shall
never be reduced and the election procedures of Section 9.01 shall apply when
changing to or from the above schedule as though the automatic change were the
result of an amendment.

The part of the Member's Vested Account resulting from the minimum contributions
required pursuant to Section 10.04 shall not be forfeited because of a period of
reemployment after benefit payments have begun or because of a withdrawal of
required contributions, if any.

SECTION 10.04  -  MODIFICATION OF CONTRIBUTIONS.

For any Plan Year in which the Plan is top-heavy, only the first $200,000
(multiplied by the Adjustment Factor) of a Member's annual compensation shall be
taken into account for purposes of determining Employer Contributions under the
Plan.

During any Year in which this Plan is a Top-heavy Plan, we shall make a minimum
contribution or allocation on the last day of the Year for each person who is a
Non-key Employee on that day and who either was or could have been an Active
Member during the Year. A Non-key Employee is not required to have a minimum
number of Hours of Service or minimum amount of Pay, or to have made any
Elective Deferral Contributions in order to be entitled to this minimum. The
selections we make in Item R shall determine if Key Employees who are Employees
on the last day of the Year are also entitled to this minimum and if the minimum
contribution or allocation shall apply in Years when this Plan is not a
Top-heavy Plan. The minimum contribution and allocation for such person shall be
equal to the amount specified in Item R. If overriding provisions are not
specified in Item R, the minimum is the lesser of (a) or (b) below:

(a)      Three percent of such person's Compensation (as defined in this
         article).

(b)     The "highest percentage" of Compensation (as defined in this article)
        for such Year at which our contributions are made for or allocated to
        any Key Employee. The highest percentage shall be determined by dividing
        our contributions made for or allocated to each Key Employee during the
        Year by the amount of his Compensation (as defined in this article)
        which is not more than the maximum set out above, and selecting the
        greatest quotient (expressed as a percentage). To determine the highest
        percentage, all our defined contribution plans within the Aggregation
        Group shall be treated as one plan. The provisions of this paragraph
        shall not apply if this Plan and a defined benefit plan of ours are
        required to be included in the Aggregation Group and this Plan enables
        the defined benefit plan to meet the requirements of Code Section
        401(a)(4) or Code Section 410.

If our contributions and allocations otherwise required under the defined
contribution plan(s) are at least equal to the minimum above, no additional
contribution or allocation shall be required. If our contributions and
allocations are less than the minimum above and our Contributions under this
Plan are allocated to Members, our Contributions (other than Elective Deferral
Contributions) shall be reallocated to provide the minimum. The remaining
Contributions shall be allocated as provided in the preceding articles of this
Plan. If our total contributions and allocations are less than the minimum above
and our Contributions under this Plan are not allocated, we shall contribute the
difference for the Year.

The minimum contribution or allocation applies to all of our defined
contribution plans in the aggregate which are Top-heavy Plans. A minimum
allocation under a profit sharing plan shall be made without regard to whether
or not we have profits. If a person who is otherwise entitled to an additional
contribution or allocation above is also covered under a defined benefit plan of
ours which is a Top-heavy Plan during that same Year, the minimum benefits for
him shall not be duplicated. The defined benefit plan shall provide an annual
benefit for him on, or adjusted


ARTICLE X                             -91-
<PAGE>   92
to, a straight life basis of the lesser of (c) two percent of his average pay
multiplied by his years of service or (d) twenty percent of his average pay.
Average pay and years of service shall have the meaning set forth in such
defined benefit plan for this purpose.

We may provide overriding provisions in Item R to satisfy the requirements of
Code Section 416 because of the aggregation of multiple plans.

For purposes of this section, any employer contribution made according to a
salary reduction or similar arrangement shall not apply before the first Yearly
Date in 1985. On and after the first Yearly Date in 1989, any such employer
contributions and employer contributions which are matching contributions, as
defined in Code Section 401(m), shall not apply in determining if the minimum
contribution requirement has been met, but shall apply in determining the
minimum contribution required. Forfeitures credited to a Member's account are
treated as employer contributions.

The requirements of this section shall be met without regard to contributions
under Chapter 2 of the Code (relating to tax on self-employment), Chapter 21 of
the Code (relating to Federal Insurance Contributions Act), Title II of the
Social Security Act or any other Federal or state law.

SECTION 10.05  -  MODIFICATION OF CONTRIBUTION LIMITATION.

If the provisions of subsection (1) of Section 3.06 are applicable for any
Limitation Year during which this Plan is a Top-heavy Plan, the Contribution
limitations shall be modified. The definitions of Defined Benefit Plan Fraction
and Defined Contribution Plan Fraction in Section 3.06 shall be modified by
substituting "100 percent" in lieu of "125 percent." In addition, an adjustment
shall be made to the numerator of the Defined Contribution Plan Fraction. The
adjustment is a reduction of that numerator similar to the modification of the
Defined Contribution Plan Fraction described in Section 3.06 and shall be made
with respect to the last Plan Year beginning before January 1, 1984.

The modifications in the paragraph above shall not apply with respect to a
Member so long as employer contributions, forfeitures or nondeductible employee
contributions are not credited to his account under this or any of our other
defined contribution plans and benefits do not accrue for such Member under our
defined benefit plan(s), until the sum of his Defined Contribution and Defined
Benefit Plan Fractions is less than 1.0.

The modification of the Contribution limitation shall not apply if both of the
following requirements are met:

(a)      This Plan would not be a Top-heavy Plan if "ninety percent" were
         substituted for "sixty percent" in the definition of Top-heavy Plan.

(b)      A Non-key Employee who is not covered under a defined contribution plan
         of ours, accrues a minimum benefit on, or adjusted to, a straight life
         basis equal to the lesser of (a) twenty percent of his average pay or
         (b) two percent of his average pay multiplied by his


ARTICLE X                             -92-
<PAGE>   93
         years of service, increased by one percentage point for each year (not
         to exceed ten in the case of (a)) earned while the benefit limitation
         is to be modified as described above.

The account of a Non-key Employee who is covered under only one or more defined
contribution plans of ours, is credited with a minimum employer contribution or
allocation under such plan(s) equal to four percent of the person's Compensation
for each year in which the plan is a Top-heavy Plan.

If a Non-key Employee is covered under both defined contribution and defined
benefit plans of ours, (i) a minimum accrued benefit for such person equal to
the amount determined above for a person who is not covered under a defined
contribution plan is accrued in the defined benefit plan(s) or (ii) a minimum
contribution or allocation equal to 7.5 percent of the person's Compensation for
a Year in which the plans are Top-heavy Plans will be credited to his account
under the defined contribution plans.

MODIFICATION OF BASIS FOR DETERMINING
MONTHLY ANNUITY BENEFITS RIDER

This rider is made a part of the Group Annuity Contract issued by us to which it
is attached. All terms defined in the contract have the same meaning where used
in this rider.

The effective date of this rider is the Contract Date unless otherwise stated in
the amendment adding this rider to the contract.

This rider modifies the contract as follows:

         1.       If you report to us that all or a part of the monthly annuity
                  income to be provided to Members or Participants under this
                  contract should be determined without regard to the sex of the
                  individual or individuals for whom the income is to be
                  provided, then:

                  a)       Sex will not be a factor used in the determination of
                           such amount of monthly annuity income, and

                  b)       the annuity purchase rates applicable for such amount
                           will be the rates available under contracts of this
                           class for purchases on a sex neutral basis on the
                           date such purchase is made. Such rates will not be
                           less favorable to the Member or Participant than the
                           rates shown in Table 1 A.

         2.       To the extent Item 1 of this rider is applicable to a Member

SEPARATE INVESTMENT RIDER

SEPARATE ACCOUNT A

This rider is made a part of the Group Annuity Contract issued by us to which it
is attached. All terms defined in the contract and any of its attached riders
have the same meaning where used in this rider.

The purpose of this rider is to allow this contract to participate in our common
stock account called Separate Account A.

The effective date of this rider is the Contract Date, unless otherwise stated
in the amendment adding it to the contract.

Pursuant to Article II, Section 6, the following is added to this contract:

         1.       SEPARATE ACCOUNT A. Separate Account A is a pooled Separate
                  Account for use by our retirement plan customers. It is
                  invested by us primarily in common stocks, other equity
                  securities, or other convertible securities that may be
                  converted to common stocks. We may also, at our option,
                  occasionally invest in short term money market instruments,
                  cash or cash equivalents. We will invest and reinvest the
                  assets held in Separate Account A in accordance with
                  applicable law, without regard to any investment requirements
                  of our general account assets or any of our other Separate
                  Accounts.

                  The investment management charge under Separate Account A is
                  based on the value of its assets. The pro-rata charge for
                  investment management will be deducted from Separate Account A
                  on each Valuation Date for the number of calendar days within
                  the Valuation Period ending on such Valuation Date.

                  The annual investment management charge for Separate Account A
                  shall not at any time exceed 1.00% of the value of its assets.
                  Currently, the annual charge is 0.36%. We reserve the right to
                  change the amount of charge for investment management up to
                  the 1.00% limit at any time by giving you written notice at
                  least 30 days before the date the change is to take effect.

         2.       DETERMINING SEPARATE ACCOUNT A VALUE; UNIT VALUES. The value
                  of Separate Account A is its market value. If there is no
                  readily available market, its value is the fair value of the
                  assets held in such Separate Account as determined by us using
                  generally accepted accounting practices and applicable law. We
                  will determine the value of Separate Account A on each
                  Valuation Date.

                  The value of Separate Account A may be expressed in units. A
                  Unit Value is the dollar value of one unit held in Separate
                  Account A. We will determine the Unit Value of Separate
                  Account A on each Valuation Date. This Unit Value is equal to
<PAGE>   99
                  the market value of Separate Account A divided by the total
                  number of Separate Account A Units on such date.

                  The initial Unit Value of one unit of Separate Account A at
                  its inception was $10.00. The Unit Value for Contributions or
                  transfers added to Separate Account A after its date of
                  inception shall be the Unit Value of Separate Account A on the
                  Valuation Date the Contribution or transfer is received at our
                  home office. If a Contribution or transfer is received on any
                  date other than a Valuation Date, the Unit Value for such
                  Contribution or transfer shall be determined on the next
                  following Valuation Date. On any Valuation Date occurring
                  after its date of inception, the Unit Value of Separate
                  Account A shall be equal to the market value of Separate
                  Account A on such date divided by the number of Separate
                  Account A Units before any adjustments for Contributions or
                  transfers to and applications from Separate Account A on such
                  date.

         3.       SEPARATE INVESTMENT A ACCOUNT. A Separate Investment A Account
                  is established for each Member for each type of Contribution
                  he directs to Separate Account A. The value of a Separate
                  Investment A Account is its proportionate share of the value
                  of Separate Account A. This value will be determined on each
                  Valuation Date by multiplying (a) by (b):

                  a)       The number of Separate Account A Units in the
                           Separate Investment A Account as of the Valuation
                           Date.

                  b)       The Separate Account A Unit Value as of the Valuation
                           Date, as determined in Item 2 of this rider.

                  Contributions or transfers to a Separate Investment A Account
                  increase the number of Separate Account A Units credited to
                  it; applications from the account reduce the number of units.
                  This increase or decrease is determined by dividing the amount
                  to be credited to or applied from the account by the Separate
                  Account A Unit Value on the Valuation Date on which a
                  Contribution or transfer was credited or an application was
                  made.

         4.       TRANSFERS AND PAYMENTS FROM A SEPARATE INVESTMENT A ACCOUNT.
                  We will, upon receipt of written request from you and/or a
                  Member, as the Plan permits,

                  a)       transfer to his General Investment Account or another
                           Separate Investment Account all or any portion of his
                           Separate Investment A Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of his Separate Investment A Account, or

                  c)       pay the Member an amount equal to all or any portion
                           of his Separate Investment A Account.
<PAGE>   100
                  The amount to be paid or transfered will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive the written request or (ii)
                  a later Valuation Date specified in the request, subject to
                  our right to defer a transfer or payment as described in Item
                  5 of this rider. We are not responsible for the application of
                  amounts transferred to an Alternate Funding Agent. The amount
                  transferred or paid will be deducted from a Separate
                  Investment A Account and will be an application from such
                  account as of the date transferred or paid. Each transfer to
                  another Separate Investment Account may occur only on a
                  Valuation Date of such Separate Investment Account.

         5.       LIMITATIONS ON TRANSFERS AND PAYMENTS FROM A SEPARATE
                  INVESTMENT A ACCOUNT. In general, transfers and payments from
                  a Separate Investment A Account normally will be made within
                  seven business days after the Valuation Date specified in Item
                  4. However, we reserve the right to defer such transfers or
                  payments for a period not to exceed 270 days.

                  However, if in the 36 month period which ends on the requested
                  date of transfer all transfers and payments from the total of
                  all Separate Investment A Accounts total $20,000,000 or more,
                  then we reserve the right to make the portion of the requested
                  transfer or payment in excess of $20,000,000 in substantially
                  equal installments over a period not to exceed 36 months. For
                  purposes of this limitation, transfers and payments from any
                  other separate investment accounts or funds included in
                  Separate Account A from any other contracts or policies issued
                  in connection with the Plan or with any other retirement plan
                  of the Employer will be included as a transfer or payment from
                  a Separate Investment A Account. If this limitation is imposed
                  by us, the first installment will be made one month after the
                  date of request, or on such later date that you specify.

                  These limitations will not apply to the payments to the
                  beneficiary of a Member.

                  If we defer any transfer or payment under this Item 5, we will
                  determine the amount to be transferred or paid on the date
                  transfer or payment occurs. We will notify you in the event of
                  any deferment of more than 30 days under the provisions of
                  this Item 5.

SEPARATE INVESTMENT RIDER

SEPARATE ACCOUNT LI

This rider is made a part of the Group Annuity Contract issued by us to which it
is attached. All terms defined in the contract and any of its attached riders
have the same meaning where used in this rider.

The purpose of this rider is to allow this contract to participate in our short
term investment account called Separate Account LI.

The effective date of this rider is the Contract Date unless otherwise stated in
the amendment adding it to the contract.

Pursuant to Article II, Section 6, the following is added to this contract:

         1.       SEPARATE ACCOUNT LI. Separate Account LI is a pooled Separate
                  Account for use by our retirement plan customers. It is
                  invested by us primarily in money market instruments such as
                  the obligations of the United States government and its
                  agencies, commercial paper, bank certificates of deposit and
                  similar such instruments. We will invest and reinvest the
                  assets held in Separate Account LI in accordance with
                  applicable law without regard to any investment requirements
                  of our general account assets or any other of our Separate
                  Accounts.

                  The investment management charge under Separate Account LI is
                  based on the value of its assets. The pro-rata charge for
                  investment management will be deducted from Separate Account
                  LI on each Valuation Date for the number of calendar days
                  within the Valuation Period ending on such Valuation Date.

                  The annual investment management charge for Separate Account
                  LI shall not at any time exceed 1.00% of the value of its
                  assets. Currently, this charge is 0.36%. We reserve the right
                  to change the amount of charge for investment management up to
                  the 1.00% limit at any time by giving you written notice at
                  least 30 days before the date the change is to take effect.

         2.       DETERMINING SEPARATE ACCOUNT LI VALUE; UNIT VALUES. The value
                  of Separate Account LI is its market value. If there is no
                  readily available market, its value is the fair value of the
                  assets held in such Separate Account as determined by us using
                  generally accepted accounting practices and applicable law. We
                  will determine the value of Separate Account LI on each
                  Valuation Date.

                  The value of Separate Account LI may be expressed in units. A
                  Unit Value is the dollar value of one unit held in Separate
                  Account LI. We will determine the Unit Value of Separate
                  Account LI on each Valuation Date. This Unit Value is equal
<PAGE>   102
                  to the market value of Separate Account LI divided by the
                  total number of Separate Account LI Units on such date.

                  The initial Unit Value of one unit of Separate Account LI at
                  its inception was $10.00. The Unit Value for Contributions or
                  transfers added to Separate Account LI after its date of
                  inception shall be the Unit Value of Separate Account LI on
                  the Valuation Date the Contribution or transfer is received at
                  our home office. If a Contribution or transfer is received on
                  any date other than a Valuation Date, the Unit Value for such
                  Contribution or transfer shall be determined on the next
                  following Valuation Date. On any Valuation Date occurring
                  after its date of inception, the Unit Value of Separate
                  Account LI shall be equal to the market value of Separate
                  Account LI on such date divided by the number of Separate
                  Account LI Units before any adjustments for Contributions or
                  transfers to and applications from Separate Account LI on such
                  date.

         3.       SEPARATE INVESTMENT LI ACCOUNT. A Separate Investment LI
                  Account is established for each Member for each type of
                  Contribution he directs to Separate Account LI. The value of a
                  Separate Investment LI Account is its proportionate share of
                  the value of Separate Account LI. This value will be
                  determined on each Valuation Date by multiplying (a) by (b):

                  a)       The number of Separate Account LI Units in the
                           Separate Investment LI Account as of the Valuation
                           Date.

                  b)       The Separate Account LI Unit Value as of the
                           Valuation Date, as determined in Item 2 of this
                           rider.

                  Contributions or transfers to the Separate Investment LI
                  Account increase the number of Separate Account LI Units
                  credited to it; applications from the account reduce the
                  number of Separate Account LI Units it holds. Such increase or
                  decrease is determined by dividing the amount to be credited
                  to or applied from the account by the Separate Account LI Unit
                  Value on the Valuation Date on which such Contribution or
                  transfer was credited or an application was made.

         4.       TRANSFERS AND PAYMENTS FROM A SEPARATE INVESTMENT LI ACCOUNT.
                  We will, upon receipt of written request from you and/or a
                  Member, as the Plan permits,

                  a)       transfer to his General Investment Account or another
                           Separate Investment Account all or any portion of his
                           Separate Investment LI Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of his Separate Investment LI Account, or

                  c)       pay to the Member an amount equal to all or any
                           portion of his Separate Investment LI Account.
<PAGE>   103
                  The amount to be paid or transferred will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive your written request or
                  (ii) a later Valuation Date specified in your request, subject
                  to our right to defer a transfer or payment as described in
                  Item 5 of this rider. We are not responsible for the
                  application of amounts transferred to an Alternate Funding
                  Agent.

                  The amount transferred or paid will be deducted from a
                  Separate Investment LI Account and will be an application from
                  that account as of the date transferred or paid. Each transfer
                  to another Separate Investment Account may occur only on a
                  Valuation Date of that Separate Investment Account.

         5.       LIMITATIONS ON TRANSFERS AND PAYMENTS FROM A SEPARATE
                  INVESTMENT LI ACCOUNT. In general, transfers and payments from
                  a Separate Investment LI Account normally will be made within
                  seven business days after the Valuation Date specified in Item
                  4. However, we reserve the right to delay transfer or payment
                  for a period not to exceed 90 days.

                  This limitation will not apply to payments to the beneficiary
                  of a Member.

                  If we defer any transfer or payment under this Item 5, we will
                  determine the amount to be transferred or paid as of the date
                  transfer or payment occurs. We will notify you in the event of
                  any deferment of more than 30 days under the provisions of
                  this Item 5.

SEPARATE INVESTMENT RIDER

REAL ESTATE SEPARATE ACCOUNT

This rider is made a part of the Group Annuity Contract issued by us to which it
is attached. All terms defined in the contract and any of its attached riders
have the same meaning where used in this rider.

The purpose of this rider is to allow the contract to participate in our Real
Estate Separate Account.

The effective date of this rider is the Contract Date unless otherwise stated in
the amendment adding it to the contract.

Pursuant to Article II. Section 6, the following is added to this contract:

         1.       REAL ESTATE SEPARATE ACCOUNT. The Real Estate Separate Account
                  is a pooled Separate Account for use by our retirement plan
                  customers. It is invested by us primarily in real estate such
                  as office buildings, industrial buildings, shopping centers,
                  retail stores, and similar property which meets the investment
                  objectives of this Account. Funds not currently committed to
                  acquire new property or needed to maintain existing property
                  will be invested in short term money market instruments, cash
                  or cash equivalents. We will invest or reinvest the assets
                  held in Real Estate Separate Account in accordance with
                  applicable law without regard to any investment requirements
                  of our general account assets or any of our other Separate
                  Accounts.

         2.       DETERMINING REAL ESTATE SEPARATE ACCOUNT VALUE; UNIT VALUES.
                  We will determine the value of Real Estate Separate Account on
                  each Valuation Date. The value of the properties held in the
                  Account is their appraised market value. Its value takes into
                  account the market value of any other assets held in the
                  Account and is reduced by any liabilities of the Account,
                  including operating expenses of the Account and a pro-rata
                  portion of our Investment Management Charge. If there is no
                  readily available market, the value of the Account is the fair
                  value of its assets, as determined by us using generally
                  accepted accounting practices and applicable law.

                  The value of Real Estate Separate Account shall be expressed
                  in units. The Unit Value for Real Estate Separate Account at
                  its inception was $100.00. Contributions or transfers
                  deposited in Real Estate Separate Account shall be converted
                  to units using the Unit Value on the Valuation Date the
                  Contribution or transfer is deposited in the Account. On any
                  Valuation Date occurring after its date of inception, the Unit
                  Value of Real Estate Separate Account shall be equal to its
                  then-current dollar value of the Account on such date divided
                  by the number of units in Real Estate Separate Account, before
                  any adjustments for Contributions or transfers to and
                  applications from the Account on such date.
<PAGE>   105
                  Operating expenses are the external expenses we incur in the
                  operation of Real Estate Separate Account and include any
                  local property management fees.

                  Investment Management Charge is an annual charge to cover
                  internal investment management expenses based on the value of
                  the assets of Real Estate Separate Account. This annual charge
                  is currently 0.96%. We reserve the right to change the amount
                  of charge by giving you written notice at least 30 days before
                  the change is to take effect.

         3.       SEPARATE INVESTMENT REAL ESTATE ACCOUNT. A Separate Investment
                  Real Estate Account is established for each Member for each
                  type of contribution he directs to Real Estate Separate
                  Account. The value of a Separate Investment Real Estate
                  Account is its proportionate share of the value of Real Estate
                  Separate Account. This value will be determined on each
                  Valuation Date by multiplying (a) by (b):

                  a)       The number of Real Estate Separate Account Units in
                           the Separate Investment Real Estate Account as of the
                           Valuation Date.

                  b)       The Real Estate Separate Account Unit Value as of the
                           Valuation Date, determined as described in Item 2 of
                           this rider.

                  Contributions or transfers to a Separate Investment Real
                  Estate Account increase the number of Real Estate Separate
                  Account Units credited to it; applications from the account
                  reduce the number of units. This increase or decrease is
                  determined by dividing the amount to be credited to or applied
                  from the Separate Investment Real Estate Account by the Real
                  Estate Separate Account Unit Value on the Valuation Date on
                  which a Contribution or transfer is deposited or an
                  application is made.

         4.       DEPOSITS. We reserve the right to defer placing Contributions
                  and transfers in Real Estate Separate Account. Placement in
                  the Account will be based on the current real estate
                  investment opportunities available to it and the amount of
                  funds needed to acquire additional property or to maintain
                  existing property.

                  Any Contributions or transfers directed to Real Estate
                  Separate Account which are deferred will instead be held in
                  our short term account, Separate Account LI, until a Valuation
                  Date when transfer to Real Estate Separate Account may be
                  made.

         5.       ORDER OF ENTRY. Since Real Estate Separate Account may not be
                  open on any given Valuation Date to accept all funds directed
                  by our customers to it, we have established the following
                  order of entry:
<PAGE>   106
                  a)       All amounts held in Separate Account LI waiting for
                           transfer to Real Estate Separate Account.

                  b)       Any amounts held in any other Separate Account or in
                           our general account which are to be transferred to
                           Real Estate Separate Account,

                  Within each of the above two categories, funds will be
                  transferred one customer at a time, in order from the oldest
                  waiting request to the newest request. All amounts held in
                  Separate Account LI which are directed to Real Estate Separate
                  Account will be transferred before any funds are transferred
                  under Item (b).

                  Normally, either all or no part of an intended transfer under
                  this rider to Real Estate Separate Account will be made. If
                  the amount of the intended transfer is greater than the amount
                  open for acceptance by Real Estate Separate Account, the
                  entire amount of the transfer will continue to be held in
                  Separate Account LI until the Valuation Date complete transfer
                  may be made. However, we and the Member may mutually agree to
                  transfer only a portion of the intended amount to Real Estate
                  Separate Account.

                  We will notify you in writing when amounts have been
                  transferred to Real Estate Separate Account.

                  A Member may revoke his request for transfer of funds to Real
                  Estate Separate Account by giving us written notice prior to
                  the date transfer is made. The notice must also include new
                  investment directions for the intended transfer.

         6.       TRANSFERS AND PAYMENTS FROM THE SEPARATE INVESTMENT REAL
                  ESTATE FUND. We will, upon receipt of written request from you
                  and/or the Member, as permitted by the Plan,

                  a)       transfer to his General Investment Account or another
                           Separate Investment Account all or any portion of his
                           Separate Investment Real Estate Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of his Separate Investment Real Estate
                           Account, or

                  c)       pay to the Member an amount equal to all or any
                           portion of his Separate Investment Real Estate
                           Account.

                  The amount to be paid or transferred will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive your written request or
                  (ii) a later Valuation Date specified in your request, subject
                  to our right to defer a transfer or payment as described in
                  Item 7 of this rider. We are not responsible for the
                  application of amounts transferred to an Alternate Funding
                  Agent.
<PAGE>   107
                  The amount transferred or paid will be deducted from the
                  Separate Investment Real Estate Account and will be an
                  application from such account as of the date transferred or
                  paid. Each transfer to another Separate Investment Account may
                  occur only on a Valuation Date of such Separate Investment
                  Account.

         7.       LIMITATIONS ON TRANSFERS FROM A SEPARATE INVESTMENT REAL
                  ESTATE ACCOUNT. In general, transfers and payments from a
                  Separate Investment Real Estate Account normally will be made
                  within seven business days after the Valuation Date specified
                  in Item 6. However, because of the illiquid nature of the
                  assets in which Real Estate Separate Account is invested, we
                  reserve the right to defer transfers or payments from a
                  Separate Investment Real Estate Account if a transfer or
                  payment would exceed the amount of cash and other liquid
                  assets held in Real Estate Separate Account, reduced by
                  amounts committed to purchase properties or needed for
                  operating expenses. Real Estate Separate Account may be
                  illiquid for indefinite periods of time because we do not
                  intend to sell properties to meet requests for transfer or
                  payment. Real Estate Separate Account will not be managed to
                  provide a liquidity pool for expected, but not yet received,
                  requests for transfer or payment.

                  If requests for transfer or payment from Real Estate Separate
                  Account are deferred, then the deferred transfers or payments,
                  when made, will be made in the following order:

                  a)       Any death benefits payable under a defined
                           contribution plan.

                  b)       All other requests for transfer or payment.

                  All death benefit payments from defined contribution plans
                  will be made before any other requests for transfer or
                  payment. Once these death benefits have been paid, other
                  requests will be paid in order of the dates we received the
                  requests.

                  Deferred transfers or payments, when paid, will be made as of
                  a Valuation Date and will be based on the Real Estate Separate
                  Account Unit Value as of the date paid.

SEPARATE INVESTMENT RIDER

PRIMART SEPARATE ACCOUNT

This rider is made a part of the Group Annuity Contract issued by us to which it
is attached. All terms defined in the contract and any of its attached riders
have the same meaning where used in this rider.

The purpose of this rider is to allow this contract to participate in our
primary bond and mortgage investment account called Primart Separate Account.

The effective date of this rider is the Contract Date unless otherwise stated in
the amendment adding it to the contract.

Pursuant to Article II, Section 6, the following is added to this contract:

         1.       PRIMART SEPARATE ACCOUNT. Primart Separate Account is a pooled
                  Separate Account for use by our retirement plan customers. It
                  is invested by us primarily in bond and mortgage type
                  investments similar to our general account. We will invest or
                  reinvest Primart Separate Account in accordance with
                  applicable law without regard to any investment requirements
                  of our general account assets or any of our other Separate
                  Accounts.

                  The investment management charge under Primart Separate
                  Account is based on the value of its assets. The pro-rata
                  charge for investment management will be deducted from Primart
                  Separate Account on each Valuation Date for the number of
                  calendar days within the Valuation Period ending on such
                  Valuation Date.

                  The annual investment management charge under Primart Separate
                  Account shall not at any time exceed 1.00% of the value of its
                  assets. Currently, the annual charge is 0.36%. We reserve the
                  right to change the amount of the current charge for
                  investment management up to the 1.00% limit at any time by
                  giving you written notice at least 30 days before the date the
                  change is to take effect.

         2.       DETERMINING PRIMART SEPARATE ACCOUNT VALUE; UNIT VALUES. The
                  value of Primart Separate Account is its market value, or
                  where there is no readily available market, the fair value of
                  the assets included in it, determined by our rules and in
                  accordance with generally accepted accounting practices and
                  applicable law and regulations. We will furnish you with a
                  copy of our rules upon request. The value of Primart Separate
                  Account shall be expressed in units. The Unit Value for
                  Primart Separate Account is the dollar value of one unit of
                  that Separate Account and is determined on each Valuation
                  Date.

                  The initial Unit Value of one unit of Primart Separate Account
                  at its inception was $100.00. The Unit Value for Contributions
                  or transfers added to the Primart Separate Account after its
                  date of inception shall be the Unit Value of Primart
<PAGE>   109
                  Separate Account on the Valuation Date the Contribution or
                  transfer is received at our home office. If a Contribution or
                  transfer is received on any date other than a Valuation Date,
                  the Unit Value for such Contribution or transfer shall be
                  determined on the next following Valuation Date. On any
                  Valuation Date occurring after its date of inception, the Unit
                  Value of Primart Separate Account shall be equal to the market
                  value of Primart Separate Account on such date divided by the
                  number of units in Primart Separate Account before any
                  adjustments for Contributions or transfers to and applications
                  from Primart Separate Account on such date.

         3.       SEPARATE INVESTMENT PRIMART ACCOUNT. A Separate Investment
                  Primart Account is established for each Member for each type
                  of Contribution he directs to Primart Separate Account.

                  The value of a Separate Investment Primart Account is its
                  proportionate share of the value of Primart Separate Account.
                  This value will be determined by multiplying (a) by (b):

                  a)       The number of Primart Separate Account Units in the
                           Separate Investment Primart Account as of the
                           Valuation Date.

                  b)       The Primart Separate Account Unit Value as of the
                           Valuation Date, determined in Item 2 of this rider.

                  Contributions or transfers to a Separate Investment Primart
                  Account increase the number of Primart Separate Account Units
                  credited to it; applications from the account reduce the
                  number of units. The increase or decrease is determined by
                  dividing the amount to be credited to or applied from the
                  account by the Primart Separate Account Unit Value on the
                  Valuation Date on which a Contribution or transfer is credited
                  or an application is made.

         4.       TRANSFERS AND PAYMENTS FROM A SEPARATE INVESTMENT PRIMART
                  ACCOUNT. We will, upon receipt of written request from you
                  and/or a Member, as the plan permits,

                  a)       transfer to his General Investment Account or another
                           Separate Investment Account all or any portion of the
                           Member's Separate Investment Primart Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of his Separate investment Primart Account,
                           or

                  c)       pay to the Member an amount equal to all or any
                           portion of his Separate investment Primart Account.
<PAGE>   110
                  The amount to be paid or transferred will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive the written request or (ii)
                  a later Valuation Date specified in the request, subject to
                  our right to defer a transfer or payment as described in Item
                  5 of this rider. We are not responsible for the application of
                  amounts transferred to an Alternate Funding Agent.

                  The amount transferred or paid will be deducted from a
                  Separate Investment Primart Account and will be an application
                  from such account as of the date transferred or paid. Each
                  transfer to another Separate Investment Account may occur only
                  on a Valuation Date of such Separate Investment Account.

         5.       LIMITATIONS ON TRANSFERS AND PAYMENTS FROM A SEPARATE
                  INVESTMENT PRIMART ACCOUNT. In general, transfers and payments
                  from a Separate Investment Primart Account normally will be
                  made within seven business days after the Valuation Date
                  specified in Item 4. However, we reserve the right to defer
                  such transfers or payments for a period not to exceed 270
                  days.

                  This limitation will not apply to payments to the beneficiary
                  of a Member.

                  If we defer any transfer or payment under this Item 5, we will
                  determine the amount to be transferred or paid as of the date
                  transfer or payment occurs. We will notify you in the event of
                  any deferment of more than 30 days under the provisions of
                  this Item 5.

SEPARATE INVESTMENT RIDER

INTERNATIONAL STOCK SEPARATE ACCOUNT

This rider is added to the Group Annuity Contract issued by us of which it is a
part. All terms defined in the contract and any of its attached riders have the
same meaning where used in this rider.

The purpose of this rider is to allow this contract to participate in our
international stock investment account called International Stock Separate
Account.

The effective date of this rider is the Contract Date, unless otherwise stated
in the amendment adding it to the contract.

This rider modifies Article l, Section 2, by adding the following paragraph to
the definition of Valuation Date:

         For purposes of the International Stock Separate Account, only those
         days on which both the net asset value of the investments is determined
         and we are open for business will be Valuation Dates. The valuation
         will occur as of 3:00 p.m. Central Standard (or Daylight Savings, if
         applicable) Time for that calendar day.

Pursuant to Article 1, Section 6, the following is added to the contract:

         1.       INTERNATIONAL STOCK SEPARATE ACCOUNT. International Stock
                  Separate Account is a pooled Separate Account for use by our
                  retirement plan customers. It is invested by us primarily in
                  stocks or other securities of corporations located outside the
                  United States. We may also, at our option, occasionally invest
                  in short term money market instruments, cash or cash
                  equivalents. Such investments may be in either United States
                  or foreign currency or equivalencies. We will invest or
                  reinvest the assets held in International Stock Separate
                  Account in accordance with applicable law, without regard to
                  any investment requirements of our general account assets or
                  any other of our Separate Accounts.

         2.       DETERMINING INTERNATIONAL STOCK SEPARATE ACCOUNT VALUE; UNIT
                  VALUES. We will determine the value of International Stock
                  Separate Account on each Valuation Date. The value of
                  International Stock Separate Account is its market value,
                  reduced by any liabilities of the account. The value of the
                  account will always be expressed in United States dollars. If
                  there is no readily ascertainable market value for some or all
                  of the account's assets, the value of such assets will be the
                  fair value of any such assets held in the Separate Account, as
                  determined by us using generally accepted accounting practices
                  and applicable law. A description of our method of
                  ascertaining fair value is available upon request.
<PAGE>   112
                  Liabilities of the account are its operating expenses and our
                  Investment Management Charge. Operating expenses are those
                  charges we must pay to operate the account, including, but not
                  limited to, custodial fees, transfer taxes, other fees or
                  taxes imposed by the country of origin, and other such
                  charges.

                  Investment Management Charge is an annual charge to pay us to
                  manage the account and is based on the value of the assets of
                  International Stock Separate Account. The pro rata charge for
                  investment management will be deducted from International
                  Stock Separate Account on each Valuation Date for the number
                  of calendar days within the Valuation Period ending on such
                  Valuation Date.

                  The annual investment management charge for International
                  Stock Separate Account shall not at any time exceed 2.00% of
                  the value of its assets. Currently, the annual charge is
                  0.60%. We reserve the right to change the amount of charge for
                  investment management up to the 2.00% limit at any time by
                  giving you written notice at least 30 days before the date the
                  change is to take effect.

                  The value of International Stock Separate Account shall be
                  expressed in units. The Unit Value is equal to the market
                  value of International Stock Separate Account divided by the
                  total number of International Stock Separate Account Units on
                  the date of determination.

                  The initial Unit Value of one unit of International Stock
                  Separate Account was $10.00. The Unit Value for Contributions
                  or transfers added to International Stock Separate Account
                  after its date of inception shall be the Unit Value of
                  International Stock Separate Account on the Valuation Date the
                  Contribution or transfer is accepted at our home office. If a
                  Contribution or transfer is received on any date other than a
                  Valuation Date, the Unit Value for such Contribution or
                  transfer shall be determined on the next following Valuation
                  Date. On any Valuation Date occurring after its date of
                  inception, the Unit Value of International Stock Separate
                  Account shall be equal to the market value of International
                  Stock Separate Account on such date divided by the number of
                  International Stock Separate Account Units before any
                  adjustments for Contributions or transfers to and applications
                  from International Stock Separate Account on such date.

         3.       SEPARATE INVESTMENT INTERNATIONAL STOCK ACCOUNT. The Separate
                  Investment International Stock Account is established for each
                  Member for each type of Contribution such Member directs to
                  International Stock Separate Account. The value of a Separate
                  Investment International Stock Account is its proportionate
                  share of the value of International Stock Separate Account.
                  This value will be determined on each Valuation Date by
                  multiplying (a) by (b):

                  a)       The number of International Stock Separate Account
                           Units in the Separate Investment International Stock
                           Account as of the Valuation Date.
<PAGE>   113
                  b)       The Unit Value of International Stock Separate
                           Account as of the Valuation Date, as determined in
                           Item 2 of this rider.

                  Contributions or transfers to a Separate Investment
                  International Stock Account increase the number of
                  International Stock Separate Account Units credited to it;
                  applications from the account reduce the number of units. This
                  increase or decrease is determined by dividing the amount to
                  be credited to or applied from the account by the Unit Value
                  of International Stock Separate Account on the Valuation Date
                  on which a Contribution or transfer was credited or an
                  application was made.

         4.       TRANSFERS AND PAYMENTS FROM A MEMBER'S SEPARATE INVESTMENT
                  INTERNATIONAL STOCK ACCOUNT. We will, upon receipt of written
                  request from you and/or a Member, as the Plan permits,

                  a)       transfer to the Member's General Investment Account
                           or another Separate Investment Account all or any
                           portion of such Separate Investment International
                           Stock Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of the Member's Separate Investment
                           International Stock Account, or

                  c)       pay to the Member an amount equal to all or any
                           portion of the Member's Separate Investment
                           International Stock Account.

                  The amount to be paid or transferred will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive the written request or (ii)
                  a later Valuation Date specified in the request, subject to
                  our right to defer a transfer or payment as described in Item
                  5 of this rider. We are not responsible for the application of
                  amounts transferred to an Alternate Funding Agent. The amount
                  transferred or paid will be deducted from the Member's
                  Separate Investment International Stock Account and will be an
                  application from such account as of the date transferred or
                  paid. Each transfer to another Separate Investment Account may
                  occur only on a Valuation Date of such Separate Investment
                  Account.

         5.       LIMITATIONS ON TRANSFERS AND PAYMENTS FROM A MEMBER'S SEPARATE
                  INVESTMENT INTERNATIONAL STOCK ACCOUNT. In general, transfers
                  and payments from a Member's Separate Investment International
                  Stock Account will be made within seven business days after
                  the Valuation Date specified in Item 4. We reserve the right,
                  however, to defer such payments or transfers for a period not
                  to exceed 270 days.

                  We may defer a transfer or payment under this Item 5 because
                  of delays generated by the sale of stock in a foreign market.
                  We will notify you if we defer a transfer or payment due to
                  such a delay. The value determined at the time we invoke the
<PAGE>   114
                  delay will be paid out when payment becomes possible; but in
                  no event will we defer payment more than 270 days.

                  If we defer transfer or payment under this Item 5 for other
                  than the sale of stock in a foreign market, we will determine
                  the amount to be transferred or paid on the actual date of
                  transfer or payment. In such a case, the Member's Separate
                  Investment International Stock Account of this contract will
                  continue to participate in the International Stock Separate
                  Account until the date transfer or payment occurs. We will
                  notify you in the event of any deferment of more than 30 days.

                  In addition, if in the 12-month period which ends on the
                  requested date of transfer all transfers and payments from the
                  total of all Separate Investment International Stock Accounts
                  total $1,000,000 or more, then we reserve the right to make
                  the portion of the requested transfer in excess of $1,000,000
                  in substantially equal monthly installments over a period not
                  to exceed 12 months. For purposes of this limitation,
                  transfers and payments from any other separate investment
                  accounts or funds included in International Stock Separate
                  Account from any other contracts or policies issued in
                  connection with the Plan or with any other retirement plan of
                  the Employer will be included as a transfer or payment from a
                  Separate Investment International Stock Account. If this
                  limitation is imposed by us, the first installment will be
                  made one month after the date of request, or on such later
                  date that you specify.

                  These limitations will not apply to the payments to the
                  beneficiary of a Member.

MULTIPLE GUARANTEE PERIODS

RIDER

This rider is made a part of the Group Annuity Contract issued by Principal
Mutual Life Insurance Company to which it is attached. All terms defined in the
contract and any of its attached riders have the same meaning where used in this
rider.

The purpose of this rider is to expand the number of Guarantee Periods available
under the contract and to permit Guarantee Periods of other than five year
durations to be established.

The effective date of this rider is the Contract Date unless otherwise stated in
the amendment adding it to the contract. However, this rider will have no effect
for any Deposit Years (as to Contributions received during such Deposit Years)
for which we do not have valid written directions selecting Guarantee Period(s).
In such Deposit Year(s), the provisions of the contract with regard to Guarantee
Period and Investment Direction will be the provisions stated in the contract as
if this rider were not in effect. In any event, directions received for a
Deposit Year after its start will not become effective until the next Deposit
Year.

This rider modifies the contract as follows:

         1.       By striking the definitions of GUARANTEE PERIOD, GUARANTEED
                  INTEREST RATE and ORDER OF APPLICATION in Article I, Section
                  2, and substituting the following definitions in lieu thereof:

                  "GUARANTEE PERIOD means the period for which a Guaranteed
                  Interest Account exists. The period or periods available may
                  be any we make available to contracts of this class under the
                  same or similar circumstances. We reserve the right, in our
                  sole discretion, to change at any time the Guarantee Periods
                  available for new Contributions and transfers, including
                  transfers from existing Guaranteed Interest Accounts. We
                  reserve the right to limit both the number of Guarantee
                  Periods available under this contract and the number available
                  to each Member.

                  You must give us written directions selecting the Guarantee
                  Periods available under the contract. Your selection will
                  remain in effect until modified by (b) or (c) below.

                  Our rights to change and to limit the Guarantee Periods
                  available are subject to the following:

                  a)       Once established by us, the Guarantee Period for a
                           particular Guaranteed Interest Account may not be
                           changed by us. A different Guarantee Period may apply
                           to amounts maturing from that Guaranteed Interest
                           Account, however.
<PAGE>   116
                  b)       If a particular Guarantee Period is no longer
                           offered, we will notify you at least sixty days
                           before the date the use of such Guarantee Period will
                           no longer be permitted.

                  c)       For each Deposit Year, you have the right to select
                           Guarantee Periods or to change the selection of
                           Guarantee Periods available to Members by filing
                           written directions with us before the beginning of
                           the Deposit Year for which the selection applies. The
                           selections for a Deposit Year cannot be changed after
                           its start.

                  GUARANTEED INTEREST RATE means the annual rates of interest we
                  declare from time to time for contracts of this class for
                  Guaranteed Interest Accounts. Each Contribution or transfer to
                  a Guaranteed Interest Account will be credited with the
                  Guaranteed Interest Rate in effect for the Guarantee Period
                  chosen on the date the Contribution was received or the
                  transfer was made.

                  ORDER OF APPLICATION means the order in which we will apply
                  the Guaranteed Interest Accounts of a Member when transfer or
                  withdrawal or a portion of his General Investment Accounts has
                  been requested and no other order of application has been
                  reported to us. Such Order of Application shall be from the
                  current Guaranteed Interest Account first and then from each
                  preceding Guaranteed Interest Account with the oldest
                  Guaranteed Interest Account being last applied. However, if
                  two or more Guaranteed Interest Accounts are established at
                  the same time, the account nearest the end of its Guarantee
                  Period shall be applied first, with the account furthest from
                  the end of its Guarantee Period being last applied."

         2.       By adding the following sentence to Article II, Section 3:

                  "If more than one Guarantee Period is available, however,
                  Contributions for a Member for whom no investment direction is
                  on file will be directed to the General Investment Account
                  with the shortest Guarantee Period then available under the
                  contract."

         3.       By adding the following sentence to Article II, Section 4:

                  "A separate General Investment Account will be established for
                  each Guarantee Period selected for each type of Contribution."

         4.       By adding the following sentence to Article II, Section 5:

                  "A separate Guaranteed Interest Account will be established
                  for each Deposit Year for each Guarantee Period used to hold
                  each type of Contribution directed to such accounts."
<PAGE>   117
         5.       By adding the following sentences to the last paragraph of
                  Article II, Section 9:

                  "Unless you or the Member (as permitted by the Plan) tell us
                  otherwise, each matured Guaranteed Interest Account will be
                  transferred to the current Guaranteed Interest Account of the
                  Member with the same Guarantee Period, if available. If the
                  same Guarantee Period is no longer available, the account will
                  be transferred to the Guaranteed Interest Account with the
                  shortest Guarantee Period available under the contract."

         SECTION 1--CONTRIBUTIONS. Contributions may be accepted by us under
this contract on any date on or after the Contract Date, subject to the
limitations of Article VII, Section 10. A Contribution on behalf of a Member is
any amount determined or allowed by the Plan to be paid to us for that Member.

         All Contributions are payable directly to us at our home office in Des
Moines, Iowa. Contributions will be received by us during our normal business
hours Monday through Friday. If received during other hours, Saturdays, and
legal holidays, they will be deemed to have been received the next following
business day.

         SECTION 2--TYPES OF CONTRIBUTIONS. A Contribution on behalf of a Member
may be any of the following types, if permitted by the Plan:

         a)       Required employee contributions. This includes all
                  contributions from the Member which the Plan requires in order
                  for the Member to participate or which are matched by employer
                  contributions.

         b)       Voluntary deductible employee contributions. This includes all
                  contributions from the Member which are deductible for federal
                  income tax purposes under Internal Revenue Code Section
                  219(a).

         c)       Other voluntary employee contributions. This includes all
                  contributions from the Member which are allowed by the Plan
                  but not included in (a) or (b) above.

         d)       Employer contributions. This includes all Employer
                  contributions permitted or required by the Plan.

         e)       Transfer, rollover, or other contributions. This includes
                  those Contributions not included in (a), (b), (c), or (d)
                  above which are permitted by the Plan and which are permitted
                  or required to be held separately for a Member.

         SECTION 3--INVESTMENT DIRECTION. Each type of Contribution on behalf of
a Member may be directed to the General Investment Account for the Member (see
Section 4 below) or to any number of the Separate Investment Accounts (see
Section 6 below) or to any combination of such accounts. We must have written
direction from you or, if the Plan permits, from the Member, for the portion of
each type of Contribution to be held in each account. Contributions will be
added to each account in the amount or percentage specified in the written
directions on file with us. Future Contributions may be directed to different
accounts or the amount directed to an account may be changed by filing a new
direction with us. If a Contribution is received for
<PAGE>   124
a Member for whom no written direction is on file with us, we will direct that
Contribution to his General Investment Account.

         SECTION 4--GENERAL INVESTMENT ACCOUNT. The General Investment Account
of a Member for a type of Contribution is the aggregate of all of his Guaranteed
Interest Accounts which have not been paid or applied in full.

         The value of a General Investment Account of a Member on any date will
be the sum of the values of the Guaranteed Interest Accounts held under it on
such date.

         SECTION 5--GUARANTEED INTEREST ACCOUNTS. A Guaranteed Interest Account
will be established for a Member for each type of Contribution directed to his
General Investment Account for each Deposit Year. All such General Investment
Account Contributions and transfers to General Investment Account for a Member
will be credited to his Guaranteed Interest Account established for the Deposit
Year in which such Contributions or transfers occur. No further Contributions or
transfers will be credited to a Guaranteed Interest Account after the close of
the Deposit Year in which it was established.

         The value of each Guaranteed Interest Account of a Member at any time
during its Guarantee Period will be determined as follows:

         a)       Initial Deposit Year.

                  1)       On any date, the value of such account will be equal
                           to the sum of all Contributions and transfers to it
                           plus interest on such Contributions and transfers
                           less any payments or applications from such account
                           on or before such date.

                  2)       Interest will be credited to such account daily and
                           compounded annually on the last day of the Deposit
                           Year.

                  3)       Interest will be credited on the Contributions and
                           transfers to such account from the date received or
                           transferred to the last day of such Deposit Year, or
                           to date of payment or transfer, if earlier.

                  4)       The rate of interest credited will be the Composite
                           Guaranteed Rate determined for such account.

                           Composite Guaranteed Rate means, as of any date, the
                           rate we determine for the Member's account which is
                           based on the Guaranteed Interest Rate in effect for
                           each Contribution or transfer to the account, the
                           amount and timing of each such Contribution or
                           transfer, and the amount of any payment or
                           application on or before such date. For second and
                           subsequent Deposit Years, the Composite Guaranteed
                           Rate will be the rate in effect on the last day of
                           the initial Deposit Year.
<PAGE>   125
         b)       Second and subsequent Deposit Years.

                  1)       On any date of determination, the value of such
                           account will be equal to the value of the last day of
                           its preceding Deposit Year, plus interest for the
                           number of days since such last day, less any payments
                           or transfers from such account since such last day.

                  2)       Interest will be credited daily and compounded
                           annually on the last day of the Deposit Year.

                  3)       Interest will be credited at the Composite Guaranteed
                           Rate from the first day of the Deposit Year to the
                           last day of the Deposit Year, or to the date of
                           payment or transfers if earlier.

         A Guaranteed Interest Account will be paid or applied in full at the
end of its Guarantee Period as described in Section 9 of this Article.

         SECTION 6--SEPARATE INVESTMENT ACCOUNT. A Separate Investment Account
is established for a Member for each type of Contribution directed to each
Separate Account in which this contract participates. The applicable Separate
Investment Rider attached to this contract describes each such Separate
Investment Account and its investment, accounting, valuation, and transfer
provisions.

         SECTION 7--HOLDING ACCOUNTS. When we are notified that an event has
occurred which requires a Member's Separate Investment Account (or Accounts) and
his General Investment Account be reduced by the provisions of the Plan, we will
reduce the account or accounts affected to the amounts specified. The amounts
deducted from the Member's accounts will be held in Holding Accounts which
correspond to the Member accounts from which they were deducted until they
become forfeitures under the Plan or again become part of Member Accounts for
such Member.

         If the Member's Holding Accounts become forfeitures, the following will
occur:

         a)       Each Holding Account for the Member for a Separate Investment
                  Account will be added to the Holding Account for forfeitures
                  for such Separate Investment Account.

         b)       Each Holding Account for the Member for a Guaranteed Interest
                  Account will be added to the Holding Account for forfeitures
                  for all Guaranteed Interest Accounts whose Guarantee Periods
                  end on the same date as such account.

         c)       Holding Accounts for forfeitures will operate in the same
                  manner as Member Holding Accounts except as follows. If the
                  Guarantee Period for a Guaranteed Interest Account ends while
                  such account is held as a forfeiture, the value of such
                  account shall be transferred to the Holding Account
                  forfeitures for the Separate Investment Account invested in
                  Separate Account LI.
<PAGE>   126
                  If such Separate Investment Account is not available under
                  this contract, the rate of interest credited to forfeitures
                  consisting of Guaranteed Interest Account values after the end
                  of the Guarantee Period for them will be the rate determined
                  by us for amounts so held under contracts of this class.

         d)       As forfeitures, Holding Account values will be allocated to
                  those Members entitled to them under the Plan and will be
                  applied on the earliest date which is consistent with Plan
                  provisions. Any amounts allocated to a Member because of this
                  Section will be considered a Contribution for him under
                  Section 1 of this Article, and the provisions of Sections 1
                  and 3 will apply.

         SECTION 8--TRANSFERS BETWEEN ACCOUNTS. In general, all or a portion of
a Member's accounts can be transferred to another account or accounts as of any
date requested subject to the following:

         a)       We must receive written direction to transfer from you or the
                  Member, as permitted by the Plan. The written direction will
                  specify, in addition to the amount to be transferred and the
                  accounts involved, the type of Contribution (see Article II,
                  Section 2) being transferred. If a requested transfer from a
                  Member's General Investment Account does not specify the
                  Guaranteed Interest Account or Accounts to be transferred, the
                  Order of Application (as defined in Article I, Section 2) will
                  determine the accounts to be transferred.

         b)       No transfer will be effective if it is within one month before
                  the Member's Annuity Commencement Date.

         c)       A transfer from a Member's General Investment Account to a
                  Separate Investment Account can occur only on a Valuation Date
                  of such Separate Investment Account.

         d)       Except as provided in Section 9 of this Article, all transfers
                  from a General Investment Account are subject to charges
                  contained in Article VI, Section 1. All transfers are subject
                  to the limitations contained in Article VI, Sections 2 and 3.

         e)       All Separate Investment Account transfers will be made subject
                  to the provisions of the Separate Investment Rider describing
                  such Separate Account.

         Any transfer under this Section will be an application from the account
from which the funds are transferred as of the date of transfer.

         SECTION 9--DISPOSITION OF A GUARANTEED INTEREST ACCOUNT AT THE END OF
ITS GUARANTEE PERIOD. Each Guaranteed Interest Account which has not been paid
or applied in full before the end of its Guarantee Period will be applied in
full on the date after its Guarantee Period ends by one or more of the following
methods:
<PAGE>   127
         a)       Transfer to Current Guaranteed Interest Account. On or before
                  the end of its Guarantee Period, you or the Member (as
                  permitted by the Plan) may make written request to us to
                  transfer all or a part of such account to the current
                  Guaranteed Interest Account of the Member for that type of
                  contribution.

         b)       Transfer to a Separate Investment Account. On or before the
                  end of its Guarantee Period, you or the Member (as permitted
                  by the Plan) may make written request to us to transfer all or
                  a part of such account to one or more of the Separate
                  Investment Accounts of the Member for that type of
                  contribution.

         c)       Purchase of Annuity. On or before the end of its Guarantee
                  Period, you or the Member (as permitted by the Plan) may make
                  written request to apply all or a portion of each account as
                  an Annuity Premium for the Member under Article IVA.

         d)       Transfer to an Alternate Funding Agent. On or before the end
                  of its Guarantee Period, you may make written request to us to
                  transfer all or a part of such account to an Alternate Funding
                  Agent. We will transfer the amount requested from such account
                  within 10 days after its Guarantee Period ends.

         If no written election has been received by us on the last day of the
Guarantee Period, item (a) will be applied by us.

         SECTION 10--FUNDS. We are sole owner of all funds received under this
contract. All General Investment Accounts we receive under this contract are and
remain a part of our general account without any duty or requirement of
segregation or separate investment on our part. Separate Investment Accounts
will be held as stated in the rider or riders describing such Separate
Investment Accounts.
<PAGE>   128
                                   ARTICLE III

                                    EXPENSES

         SECTION 1--EXPENSES. Expense charges will be determined by us
periodically, but at least annually, in accordance with the written service
agreement we have with you. The amount of such charges will be made up of the
following:

         a)       Compensation paid or payable by us to the soliciting agent
                  named by you on Contributions received by us since the last
                  date expenses were paid.

         b)       A general administration expense charge, as shown in the
                  service agreement, which is calculated for each period based
                  on the average account balances under the contract during the
                  period. (We will apply this charge in a uniform manner to all
                  contracts of this class that we issue.)

         c)       A recordkeeping expense charge for keeping individual records
                  of the various types of contribution accounts for Members
                  under this contract, and for preparing materials to inform
                  Members about their accounts under this contract.

         d)       Other charges may be made for services you ask us to do that
                  are not covered by (a) through (c) above, for example,
                  preparing the summary plan description if we do not hold all
                  Plan assets or if the Employer requests unusual material. We
                  will inform you of the charges for such services before we
                  perform them.

         We may agree to take into account any Associated Contracts for the
purpose of determining the expenses charged under such contracts. The charges
under an Associated Contract will not be greater than if it were not an
Associated Contract.

         Associated Contract(s) means this contract and any other group annuity
contract(s) issued by us which we have agreed in writing to treat as Associated
Contracts.

         These expenses may be paid to us directly at our home office in Des
Moines, Iowa. We will send you a statement of these charges periodically in
accordance with our written service agreement with you. Such charges must be
paid within 31 days from the date of the statement. If the expense charges are
not paid within 31 days after the statement date, we will deduct them from the
Holding Accounts and the Member's General Investment Accounts and Separate
Investment Accounts as set out in Section 2 of this Article. If this automatic
deduction of expenses occurs twice in any twenty-four (24) month period, we will
deduct expenses from the accounts as described in Section 2 of this Article
thereafter until a new written service agreement is completed with us.

         SECTION 2--DEDUCTION OF EXPENSES. In your written service agreement
with us (or as provided in Section 1 of this Article), an election may be made
to have some or all of the expense charges (described in Section 1 above)
deducted from Member accounts instead of having these charges paid separately.
<PAGE>   129
         These expense charges will be deducted as due from the appropriate
General Investment Accounts, Separate Investment Accounts, and Holding Accounts
and will be an application from each such account when deducted. For General
Investment Accounts, such charges will be (i) deducted from the Guaranteed
Interest Accounts for the current Deposit Year, if any, or (ii) if no current
Deposit Year Guaranteed Interest Account has been established under such General
Investment Account (or if it is insufficient), such deductions will be made from
the Guaranteed Interest Account most recently established under it.

         If you agree to pay these charges separately and a portion remains
unpaid 31 days after the statement date, we will deduct this unpaid portion in
an equitable manner from the account or accounts of the participants in the plan
to which the expenses are attributable.

                                    BENEFITS

         SECTION 1-DISTRIBUTION OF BENEFITS. Benefits will be payable to a
Member or a beneficiary under this contract as an annuity as described in
Article IVA or in a single sum payment as described in Article 1VB.

         Benefits may be payable because of a Member's

         a)       Termination of Employment,

         b)       retirement (whether early, normal or late),

         c)       disability,

         d)       death, or

         e)       withdrawal

         depending upon the Plan provisions.
<PAGE>   131
                                   ARTICLE IVA
                                ANNUITY BENEFITS

         SECTION 1 --PURCHASE OF ANNUITY. An annuity will be purchased for a
Member, payable under any option of Section 2 of this Article, as long as the
purchase conforms to Plan provisions and complies with the following:

         a)       The amounts available to purchase an annuity may be all or a
                  portion of the amount available under the Plan, as reported to
                  us by you.

         b)       You or the Member, as permitted by the Plan, must make the
                  request to us to purchase, using a form we either furnish or
                  approve.

         c)       If no optional form of income is elected, the Normal Income
                  Form will be purchased.

         d)       The Annuity Premium applied for the Member must be at least
                  $1,750. (If the Member has had other purchases under this
                  contract, this provision does not apply.)

         e)       You or the Member, as permitted by the Plan, must specify what
                  portion of the Annuity Premium is to purchase Fixed Dollar
                  Annuity. A transfer between accounts under Article II, Section
                  8, may be made to purchase the portion of Fixed Dollar Annuity
                  requested. We will apply a Member's General Investment
                  Accounts to purchase Fixed Dollar Annuity.

         f)       Any other amounts applied, not included in (e) above, will
                  purchase Fixed Dollar Annuity as specified in the request to
                  purchase.

         g)       The form of annuity and the contingent annuitant named (if
                  any) cannot be changed after Annuity Purchase Date.

         h)       Annuity Commencement Date will be the Member's Annuity
                  Purchase Date.

         SECTION 2--OPTIONS. Any of the options described below may be chosen as
the form of income to be paid for an annuity purchased under Section 1.

         Option 1--Life Annuity. This provides monthly annuity payments to the
   Member, starting on his Annuity Commencement Date and continuing for his
   life, with no further payments due after the Member's death.

         Option 2--Life Annuity with Certain Period. This provides monthly
   annuity payments to the Member, starting on his Annuity Commencement Date and
   continuing for his life. If the Member dies after his Annuity Commencement
   Date but before payments as to him have
<PAGE>   132
   been made for a certain period, the payments left for that certain period
   will be continued to the Member's beneficiary.

         In choosing this option, the following items must be reported to us:

         a)       The length of the certain period (5, 10, or 15 years).

         b)       Whether the remaining payments are to be paid as due to the
                  beneficiary or commuted and paid in a single sum.

         c)       The beneficiary named by the Member to whom remaining payments
                  are to be made.

         Option 3--Survivorship Annuity with Installment Refund. This provides
   monthly annuity payments to the Member, starting on his Annuity Commencement
   Date and continuing for his life. If the Member dies after his Annuity
   Commencement Date, a fraction of the monthly annuity will be continued to the
   contingent annuitant named by the Member for the lifetime of the contingent
   annuitant. If both the Member and the contingent annuitant die after
   commencement but before his Annuity Premium has been paid out, the rest of
   his Annuity Premium will be paid to his beneficiary in monthly payments. The
   monthly payments to the beneficiary will be the same amount as the last
   monthly payment made by us before the payment to the beneficiary is due.

         In choosing this option, the following items must be reported to us:

         a)       The fraction to be continued (1/2, 2/3, or 1).

         b)       The name, date of birth, and sex of the contingent annuitant.

         c)       The beneficiary named by the Member to whom any remaining
                  payments would be made.

         Option 4--Single Life Installment Refund Annuity. This provides monthly
   annuity payments to the Member, starting on his Annuity Commencement Date and
   continuing for his life. If the Member dies after his Annuity Commencement
   Date and before monthly payments to him total his Annuity Premium, then
   monthly payments will continue to his beneficiary until the total of monthly
   payments made equal the Annuity Premium.

         In choosing this option, the name of the beneficiary to whom the
   remaining payments are to be made must be reported to us.

         Option 5--Fixed Period Annuity. This provides monthly annuity payments
   to the Member, starting on his Annuity Commencement Date and continuing for a
   stated (fixed) period. If the Member dies after his Annuity Commencement Date
   but before payments as to him have been made for the stated period, any
   payments remaining for this period will be paid to his beneficiary.
<PAGE>   133
         In choosing this option, the following items must be reported to us:

         a)       The number of years the period is to run (not less than 5).

         b)       Whether remaining payments are to be paid as due to the
                  beneficiary or commuted and paid in a single sum.

         c)       The beneficiary named by the Member to whom remaining payments
                  would be made. By written agreement with you, we may provide
                  other options permitted by the Plan.

         SECTION 3--AMOUNT OF MONTHLY ANNUITY. The amount of monthly Fixed
   Dollar Annuity purchased under Section 1 of this Article and payable to a
   Member will be determined by us based on

         a)       the Annuity Premium for such portion,

         b)       the option chosen,

         c)       the age and sex of the Member,

         d)       the Annuity Purchase Date,

         e)       the age and sex of the contingent annuitant (if any), and

         f)       the annuity purchase rates applicable (for purchases under all
                  contracts of this class issued by us) on the date of purchase.
                  However, the annuity purchase rates used will not be less
                  favorable to the Member than the rates shown in Table 1.

         SECTION 4-CANCELLATION OF ANNUITY. If, under the provisions of the Plan
in effect on a Member's Annuity Purchase Date, you determine and report to us
that the monthly annuity purchased for a Member is to be reduced, then the
fraction you report of Fixed Dollar Annuity purchased for that Member will be
cancelled, and the amount of monthly annuity payments paid to the Member, his
beneficiary or contingent annuitant will be reduced accordingly.

         The reserve for any annuity cancelled under this Section will be
treated as a forfeiture under Article II, Section 7.
<PAGE>   134
                                   ARTICLE IVB

                               SINGLE SUM PAYMENTS

         SECTION 1--CASH TERMINATION, RETIREMENT OR DISABILITY BENEFITS. All or
a portion of the amounts available to a Member under this contract may be paid
to him by us in a single sum on or after his Termination of Employment or his
retirement under the Plan or his disability under the Plan if

         a)       the Plan allows such payment, and

         b)       we receive a written request from you and the Member, using a
                  form we either furnish or approve.

         The amount available will be determined as of the date we receive the
request at our home office, or some later date specified in the request. It will
consist of that part of the Member's accounts in which he is vested under the
vesting provisions of the Plan.

         Any amount payable to a Member under this Section is subject to the
delay of payment and limitation provisions of Article VI, Sections 2 and 3, but
such amount is not subject to the charges contained in Article VI, Section 1.

         Any payment made because of this Section will be an application equal
to the amount of payment from the account or accounts involved on the date paid
and it will be in lieu of any other benefits available under this contract for
the amounts applied.

         SECTION 2--BENEFITS PAYABLE AT DEATH.

         Subsection (1)--Before Annuity Purchase Date. If a Member dies before
his Annuity Purchase Date, a benefit equal to his vested accounts will be
payable to his beneficiary. Upon receipt of due proof of death, we will pay this
benefit in accordance with Plan provisions. If the Plan does not provide for
another method, or if no other method has been chosen, we will pay this benefit
to the beneficiary in a single sum. We will determine the value of these
accounts as of the date proof of death is received at our home office.

         There is no charge under Article VI, Section 1 for a payment made under
this Section, nor is such payment subject to the delay of payment and limitation
provisions of Article VI, Section 2.

         Subsection (2)--After Annuity Purchase Date. If a Member dies after his
Annuity Purchase Date, benefits will be paid under the form of annuity in effect
for him.

         Subsection (3)--Proof of Death. We will accept as due proof of death a
copy of a certified death certificate, a copy of a certified decree of a court
of competent jurisdiction as to the finding of death, a written statement by a
medical doctor who attended the deceased during his last illness, or any other
proof that is satisfactory to us.
<PAGE>   135
         SECTION 3--OPTIONS FOR BENEFITS PAYABLE AT DEATH. By written direction
to us, a Member may have an annuity purchased for his beneficiary under a
supplementary contract. Any such purchase must conform to the requirements of
our supplementary contract.

         If no such written direction is on file with us, a beneficiary may
choose to make such a purchase, subject to any requirements under the
supplementary contract we make available to the beneficiary.

         Any election under this Section shall be in lieu of any benefits
payable under Section 2 of this Article.

         SECTION 4--WITHDRAWAL BENEFIT. Upon written request from you and a
Member, we will pay to that Member any portion of the amounts available to him
under this contract, subject to the following:

         a)       The request must be before the Member's Termination of
                  Employment, disability or retirement.

         b)       The Plan must allow for such withdrawal.

         c)       Any amount withdrawn under this Section will be subject to
                  both the delay of payment and limitation provisions of Article
                  VI, Sections 2 and 3, and the charges of Article VI, Section
                  1.

         d)       The request must be on a form we either furnish or approve and
                  will be accompanied (at our request) by the Member's
                  certificate, if any, issued as described in Article VII,
                  Section 1.

         We will determine the amount available as of the date we receive the
request at our home office, or at some later date specified in the request. The
amount available will be that portion of his Separate Investment Account and his
General Investment Account in which he is vested under the Plan.

         If a portion of a Member's General Investment Account is to be
withdrawn, the written request must specify which Guaranteed Interest Account or
Accounts are to be applied. If none is specified, the Order of Application
(defined in Article I, Section 2) will apply.

         Any payment under this Section will be an application of the portion
requested from the account or accounts involved on the date paid. This payment
will be in lieu of any other benefits under this contract for the portions
applied.

                 TRANSFER TO ALTERNATE FUNDING AGENT; CESSATION

         SECTION 1 --TRANSFER TO ALTERNATE FUNDING AGENT. You may file a written
request with us at our home office for payment of the aggregate of all or a
portion of the General Investment Accounts and Separate Investment Accounts to
an Alternate Funding Agent. Subject to charges provided for in Article VI,
Section 1, and the limitations provided in Article VI, Sections 2 and 3, the
amount of any General Investment Accounts and Separate Investment Accounts to be
transferred will be determined and transferred within seven business days after
the date we receive your request. If you request payment as of some later date,
the amounts to be paid out will be determined and paid as of that later date.

         If only a portion of the General Investment Accounts or Separate
Investment Accounts is to be transferred, we will reduce the account or accounts
specified in your written request by the portion requested. If the Guaranteed
Interest Account or Accounts to be transferred is not specified, the Order of
Application (defined in Article I, Section 2) will apply.

         Alternate Funding Agent means an insurance company or trustee
designated by you and authorized to receive any amount or amounts transferred
under this Section as to a Member or Members and to apply such amount or amounts
for the exclusive benefit of such a Member or Members under a plan which
continues to meet the requirements of the Internal Revenue Code, without any
obligation on our part as to such application.

         SECTION 2--CESSATION OF CONTRIBUTIONS. Cessation of Contributions shall
be effective as of any of the following dates:

         a)       On the date you notify us in writing that cessation of
                  Contributions is to occur.

         b)       On the date the Plan terminates.

         c)       On the date the Plan fails to meet the requirements of the
                  Internal Revenue Code if we have given you written notice that
                  cessation is to be effective as of such date.

         d)       On the date no General Investment Accounts or Separate
                  Investment Accounts remain under this contract.

         Upon cessation of Contributions, no further employees will become
Members and no further Contributions will become payable.

         All provisions of this contract will remain effective as to any General
Investment Accounts and Separate Investment Accounts which have not been paid or
applied in full.

         Once all General Investment Accounts and Separate Investment Accounts
have been paid or applied in full, we will have no further obligation in regard
to such accounts.

                                   ARTICLE VI

                             CHARGES AND LIMITATIONS

         SECTION 1-CHARGES FOR SURRENDER OF A GUARANTEED INTEREST ACCOUNT.
Transfer or withdrawal of a Guaranteed Interest Account during its Guarantee
Period as provided in Article II, Section 8; Article IVB, Section 4; and Article
V, Section 1 is a surrender of the portion of the account so transferred or
withdrawn. If, however, the transfer under Article V, Section 1 is on account of
the death, Termination of Employment, disability, or retirement of a Member and
could have been a payment under Article IVB, Section 1 or Section 2, charges
under this Section will not be made.

         If all or a portion of a Guaranteed Interest Account is surrendered,
the amount available will be reduced by a surrender charge equal to the
following:

         a)       If the Guaranteed Interest Rate in effect for contracts of
                  this class for the date of surrender is equal to or less than
                  the Composite Guaranteed Rate for such account, there is no
                  charge.

         b)       If the Guaranteed Interest Rate in effect for contracts of
                  this class for the date of surrender is greater than the
                  Composite Guaranteed Rate for such account, such charge is
                  equal to

                  i)       the difference between such Guaranteed Interest Rate
                           for such date of surrender and such Composite
                           Guaranteed Rate multiplied by

                  ii)      the number of years (including fractional parts of a
                           year) remaining in the Guarantee Period for such
                           Guaranteed Interest Account multiplied by

                  iii)     the amount being surrendered.

         If the entire account is surrendered, such Guaranteed Interest Account
will be applied on the date of surrender and the difference between the amount
applied and the surrender charge (if any) determined above will be paid or
transferred.

         If a portion of the account is surrendered, the amount applied will be
equal to the amount being surrendered plus the surrender charge, if any.

         SECTION 2--LIMITATIONS ON TRANSFERS AND PAYMENTS FROM GENERAL
INVESTMENT ACCOUNTS. In general, payments and transfers from the General
Investment Accounts will be made in full within 90 days after the requested date
of payment. We may, at our option, delay such payment or transfer for up to an
additional 180 days.

         However, if in the 36-month period which ends on the requested date of
payment or transfer all payments or transfers from the General Investment
Accounts total $12,000,000 or more, then the portion of the requested payment or
transfer in excess of $12,000,000 may be made in substantially equal monthly
installments over a period not greater than the following 36 months.
<PAGE>   138
For purposes of this limitation, payments and transfers from our general account
from any other contracts or policies we issued in connection with the Plan or
with any other retirement plan of the Employer will be included as payment or
transfer from the General Investment Accounts. If this limitation is effective,
the first installment will be made one month after the date of request, or on
such later date that you specify.

         Nothing in any of the limitations described above will apply to
payments to the beneficiary of a Member. or to applications of Annuity Premium.

         If a deferment is applied by us under this Section, amounts to be paid
or transferred will continue to earn interest at the rate determined pursuant to
Article II, Section 5, until the date payment or transfer occurs. Any surrender
charges applicable under Section 1 of this Article will be determined as of the
date payment or transfer occurs under this Section. We will notify you in the
event of any deferment of more than 30 days under the provisions of this
Section.

         SECTION 3--LIMITATIONS ON TRANSFERS AND PAYMENTS FROM SEPARATE
INVESTMENT ACCOUNTS. Any limitation on the payment or transfer from a Separate
Investment Account is contained in the rider describing such Separate Investment
Account.
<PAGE>   139
                                   ARTICLE VII

                               GENERAL PROVISIONS

         SECTION 1-CERTIFICATES. If a Member contributes under the Plan and the
state of issue so requires, we will prepare and send to the Employer, for
delivery to each such Member, an individual certificate setting out a statement
of the benefits to which that Member is entitled and to whom death benefits are
payable. If benefits become payable to a Member under one of the options of
Article IVA, we will issue an individual certificate setting forth the amount,
form and period of payment of the monthly annuity benefits.

         SECTION 2--BENEFICIARY. The beneficiary is the person or persons named
by the Member to whom benefits (other than any monthly income payable to a
contingent annuitant under the provisions of Article IVA, Section 2) are payable
under this contract upon the death of the Member, subject to the provisions of
Section 13 of this Article. A Member shall name or change a beneficiary by
filing a written beneficiary designation to that effect with us, but the
designation will not be effective until we receive it. When we receive the
designation, it will be effective as of the date it is executed, but any
payments we made before receipt of the designation shall discharge us to the
extent of such payments. We reserve the right to require the Member's
certificate for endorsement of any change of beneficiary.

         Unless otherwise specified by the Member with our consent,

         a)       if any beneficiary dies before the Member, any monthly payment
                  which would have become payable to such beneficiary, if
                  living, will be payable when due to the beneficiary or
                  beneficiaries surviving the Member in the order provided.

         b)       if any beneficiary survives the Member but dies before
                  receiving all of the monthly payments which would have been
                  payable to such beneficiary, if living, payment will be paid
                  when due to the surviving beneficiary or beneficiaries in the
                  order provided.

         c)       if the last survivor of all named beneficiaries dies after the
                  death of the Member (and the contingent annuitant, if any) and
                  before all payments due the beneficiary have been made, the
                  remaining payments will be commuted and the commuted value
                  paid to the executor or administrator of the estate of such
                  last survivor.

         If no named beneficiary survives the Member (and the contingent
annuitant, if any), or no beneficiary has been named, any amount which would
have become payable to a beneficiary will be commuted and the commuted value
paid to the executor or administrator of the estate of the Member (the executor
or administrator of the estate of any contingent annuitant, if he survives the
Member).

         If the beneficiary is not a natural person taking in his own right
(that is, a trust or an estate), any monthly or other periodic payments will be
commuted and the commuted value paid to the beneficiary in a single sum.
However, if the beneficiary is a trust established for the benefit of a
<PAGE>   140
natural person and if the payment period is at least 24 months and not more than
60 months, monthly or other periodic payments may be continued to such
beneficiary.

         SECTION 3--DIVIDENDS. Any portion of the divisible surplus that we
determine to accrue on this contract shall be determined annually by us and
shall be credited to this contract on each Yearly Date after the Contract Date.
Any dividend shall be applied as directed by you in accordance with Plan
provisions. (NOTE: Because of the direct crediting of investment return to both
General Investment Accounts and Separate Investment Accounts, it is not
anticipated that there will be any surplus accruing on this contract from which
dividends may be apportioned to this contract.)

         SECTION 4--CONTRACT. This contract and your application, a copy of
which is attached to and made a part of this contract, are the entire contract
between the parties. We are obligated only as provided in this contract and are
not a party to nor bound by any trust or plan.

         SECTION 5--PLAN AND PLAN AMENDMENTS. You agree to furnish us with a
copy of the Plan in effect on the Contract Date and any subsequent amendments to
it. No amendment to the Plan which affects our duties and obligations will be
effective under this contract if we notify you in writing that such change is
unacceptable to us. We agree to notify you within 60 days after we receive an
amendment if it is unacceptable.

         SECTION 6--WAIVER AND MODIFICATION. Only our officers have authority to
change this contract or waive any of its provisions or requirements.

         SECTION 7--MISSTATEMENTS. If the age or sex (to the extent sex is a
determining factor) of any Member or contingent annuitant or if any other
relevant fact is found to have been misstated, the amount of annuity payable by
us will be that provided by the amount applied to purchase such annuity,
determined as of the date of purchase established by the misstated information
and on the basis of the correct age and sex. Any overpayment by us resulting
from any misstatements will be deducted from amounts thereafter payable to the
Member, his contingent annuitant or his beneficiary. Any underpayment by us
resulting from any misstatements will be paid in full with the next payment due
the Member, his contingent annuitant or his beneficiary.

         SECTION 8--INFORMATION, PROOFS AND DETERMINATION OF FACTS. You agree to
furnish to us evidence of the age of each Member and his contingent annuitant,
if any, on or before his earliest Annuity Purchase Date and other records, data,
proofs or additional information which, in our opinion, is necessary for the
administration of this contract.

         For the purposes of this contract, the determination by you as to any
facts (except age and sex) relating to any employee is, except for fraud or
willful misstatement of fact, conclusive.

         SECTION 9--AMENDMENT. We reserve the right to amend or change this
contract as follows, subject to the limitations of item (f):
<PAGE>   141
         a)       Any or all of the contract provisions may be changed at any
                  time, including retroactive changes, to the extent necessary
                  to meet the requirements of any law or regulation issued by
                  any governmental agency to which we are subject.

         b)       As of any date after the Contract Date and subject to the
                  notice provisions of (e) of this Section, we may amend or
                  change the length of the Guarantee Period; the Order of
                  Application; the provisions for transferring values between
                  accounts; and the charge contained in Article VI, Section 1.

         c)       We may amend or change Table 1 as of any date which is at
                  least 5 years after the later of (i) the Contract Date or (ii)
                  the date of the latest amendment or change under this item
                  (c).

         d)       By written agreement between you and us, this contract may be
                  amended or changed at any time as to any of its provisions,
                  including those in regard to coverage, benefits and the
                  participation privileges, without the consent of any Member,
                  beneficiary or contingent annuitant.

         e)       We will give you written notice of any change made because of
                  item (a) above. Any amendment or change under items (b) or (c)
                  will not become effective unless we give you written notice at
                  least 60 days before the date the amendment or change is to
                  take effect.

         f)       Any amendment or change under this Section 9 is binding and
                  conclusive on each Member, beneficiary, or contingent
                  annuitant, but is limited by the following:

                  i)       No amendment or change will apply to annuities
                           purchased under Article IVA before the effective date
                           of the amendment or change except to the extent
                           necessary in making changes in accordance with item
                           (a) above.

                  ii)      No amendment or change under (b) above will affect
                           Guaranteed Interest Accounts established prior to the
                           date of the amendment or change.

                  iii)     Any change in the general administration expense
                           charge referred to in (b) of Section 1, Article III,
                           will not take effect as to any General Investment
                           Accounts and Separate Investment Accounts to be
                           transferred to an Alternate Funding Agent, if, prior
                           to the date the amendment or change is to take
                           effect, we receive written request from you for
                           payment of all such General Investment Accounts and
                           Separate Investment Accounts to the Alternate Funding
                           Agent in accordance with Article V, Section 1, and
                           such request is not revoked.

         SECTION 10--CONTRIBUTIONS. We reserve the right to limit or refuse
further Contributions or Annuity Premiums under this contract. We will give you
written notice at least 60 days before the date after which further
Contributions or Annuity Premiums will be limited or refused by us.
<PAGE>   142
         SECTION 11--MODIFICATION IN MODE OF PAYMENT OF ANNUITY. If, at any time
on or subsequent to a Member's Annuity Commencement Date, the monthly amount of
the annuity payable under this contract to such Member or to his beneficiary or
contingent annuitant would be less than $20, we may, at our option, pay in cash
the reserve for the annuity payments in full settlement of all benefits
otherwise payable. The reserve will be determined by us on the same mortality
and interest basis as the annuity purchase rate which was used to determine the
amount of annuity payments.

         If, after a Member's Termination of Employment has occurred, the total
of his Separate Investment Accounts and General Investment Accounts is less than
$1,750, we, at our option, may pay to such Member the amount of such accounts in
a single sum in lieu of any and all other benefits as to such accounts.

         SECTION 12--COMMUTATION OF PAYMENTS. If any monthly payments are to be
commuted, commuted value of the payments will be determined by us, using the
interest rate which was used as a basis for calculating the amount of the
monthly payments at the time the annuity was purchased.

         Neither the Member, the contingent annuitant nor any beneficiary who is
a natural person taking in his own right has the right to commute any monthly
annuity payments under this contract.

         SECTION 13--FACILITY OF PAYMENT. If any Member, contingent annuitant or
beneficiary is physically or mentally incapable of giving a valid receipt for
any payment due him and no legal representative has been appointed for him, we
may, in the absence of written direction to the contrary from you, at our
option, make such payment to the person or persons as have, in our opinion,
assumed the care and principal support of the Member, contingent annuitant or
beneficiary, except that any payment due a minor will be paid at a rate not
exceeding $100.00 per month. However, in no event will any such payment exceed
the maximum amount allowed under applicable law of the state in which this
contract is delivered. Any such payment made by us shall fully discharge us to
the extent of the payment.

         SECTION 14--PRONOUNS. Masculine pronouns used in this contract include
both masculine and feminine gender unless the context indicates otherwise.

         SECTION 15--ASSIGNMENT. No benefits payable under this contract to any
Member, beneficiary or contingent annuitant are assignable, and all such
benefits are exempt from the claims of creditors to the maximum extent permitted
by law.

         SECTION 16--BASIS OF ANNUITY PURCHASES. The rates shown in the Table 1
included in this contract on the Contract Date have been computed on the basis
of (i) interest at the rate of 3% per annum and (ii) mortality according to the
a-1949 Male Annuity Table (Modified Projection C) with 1960 modifications in the
rates of mortality, projected 30 years, males set forward one year in age,
females set back four years in age.

         SECTION 17--INVESTMENT MANAGER. As set out in Article II, Sections 3,8
and 9, the right to direct the split of Contributions between General Investment
Accounts and Separate
<PAGE>   143
Investment Accounts and to direct any transfer between these accounts is
reserved to you and/or the Member, all in accordance with provisions of this
contract.

         Application for and issuance of this contract constitutes appointment
of and acceptance and affirmation by us that (i) we are an Investment Manager as
described under the Employee Retirement Income Security Act of 1974 with respect
to Plan assets held under this contract, except the right reserved in the
preceding paragraph and (ii) we are qualified to accept such appointment and
acknowledge that by virtue of such appointment we are a fiduciary of the Plan,
within the meaning of the Employee Retirement Income Security Act of 1974 with
respect to our responsibilities as Investment Manager.

         SECTION 18--OWNERSHIP. You are the owner of this contract; provided
however that if the Plan is trusteed, the trustee(s) of the Plan is sole owner
of all the payments, rights, options, and privileges herein granted or made
payable to any Member, beneficiary, or contingent annuitant under this contact.
This includes, without limitation, the right to distribute all or a portion of
the Member's accounts, or ownership of these rights in respect of such accounts,
on or after the Member's Termination of Employment; but this does not include
the right to designate a Member's beneficiary unless such right has been granted
to the trustee by the Plan or trust. The trustee(s) of the Plan is entitled to
exercise all such rights, options, and privileges and to receive all such
payments at the time or times specified in this contract that such payments,
rights, options, and privileges are available to a Member. Such exercise by the
trustee(s) may be made without the consent or participation of any Member,
beneficiary or contingent annuitant.

SEPARATE INVESTMENT RIDER

REAL ESTATE SEPARATE ACCOUNT


This rider is made a part of the Group Annuity Contract issued by us to which it
is attached. All terms defined in the contract and any of its attached riders
have the same meaning where used in this rider.

The purpose of this rider is to allow the contract to participate in our Real
Estate Separate Account.

The effective date of this rider is the Contract Date unless otherwise stated in
the amendment adding it to the contract.

Pursuant to Article II, Section 6, the following is added to this contract:

         1.       REAL ESTATE SEPARATE ACCOUNT. The Real Estate Separate Account
                  is a pooled Separate Account for use by our retirement plan
                  customers. It is invested by us primarily in real estate such
                  as office buildings, industrial buildings, shopping centers,
                  retail stores, and similar property which meets the investment
                  objectives of this Account. Funds not currently committed to
                  acquire new property or needed to maintain existing property
                  will be invested in short term money market instruments, cash
                  or cash equivalents. We will invest or reinvest the assets
                  held in Real Estate Separate Account in accordance with
                  applicable law without regard to any investment requirements
                  of our general account assets or any of our other Separate
                  Accounts.

         2.       DETERMINING REAL ESTATE SEPARATE ACCOUNT VALUE; UNIT VALUES.
                  We will determine the value of Real Estate Separate Account on
                  each Valuation Date. The value of the properties held in the
                  Account is their appraised market value. Its value takes into
                  account the market value of any other assets held in the
                  Account and is reduced by any liabilities of the Account,
                  including operating expenses of the Account and a pro-rata
                  portion of our Investment Management Charge. If there is no
                  readily available market, the value of the Account is the fair
                  value of its assets, as determined by us using generally
                  accepted accounting practices and applicable law.

                  The value of Real Estate Separate Account shall be expressed
                  in units. The Unit Value for Real Estate Separate Account at
                  its inception was $100.00. Contributions or transfers
                  deposited in Real Estate Separate Account shall be converted
                  to units using the Unit Value on the Valuation Date the
                  Contribution or transfer is deposited in the Account. On any
                  Valuation Date occurring after its date of inception, the Unit
                  Value of Real Estate Separate Account shall be equal to its
                  then-current dollar value of the Account on such date divided
                  by the number of units in Real Estate Separate Account, before
                  any adjustments for Contributions or transfers to and
                  applications from the Account on such date.

                  Operating expenses are the external expenses we incur in the
                  operation of Real Estate Separate Account and include any
                  local property management fees.

                  INVESTMENT MANAGEMENT CHARGE is an annual charge to cover
                  internal investment management expenses based on the value of
                  the assets of Real Estate Separate Account.


                                      -2-
<PAGE>   168
                  This annual charge is currently 1.05%. We reserve the right to
                  change the amount of charge by giving you written notice at
                  least 30 days before the change is to take effect.

         3.       SEPARATE INVESTMENT REAL ESTATE ACCOUNT. A Separate Investment
                  Real Estate Account is established for each Member for each
                  type of contribution he directs to Real Estate Separate
                  Account. The value of a Separate Investment Real Estate
                  Account is its proportionate share of the value of Real Estate
                  Separate Account. This value will be determined on each
                  Valuation Date by multiplying (a) by (b):

                  a)       The number of Real Estate Separate Account Units in
                           the Separate Investment Real Estate Account as of the
                           Valuation Date.

                  b)       The Real Estate Separate Account Unit Value as of the
                           Valuation Date, determined as described in Item 2 of
                           this rider.

                  Contributions or transfers to a Separate Investment Real
                  Estate Account increase the number of Real Estate Separate
                  Account Units credited to it; applications from the account
                  reduce the number of units. This increase or decrease is
                  determined by dividing the amount to be credited to or applied
                  from the Separate Investment Real Estate Account by the Real
                  Estate Separate Account Unit Value on the Valuation Date on
                  which a Contribution or transfer is deposited or an
                  application is made.

         4.       DEPOSITS. We reserve the right to defer placing Contributions
                  and transfers in Real Estate Separate Account. Placement in
                  the Account will be based on the current real estate
                  investment opportunities available to it and the amount of
                  funds needed to acquire additional property or to maintain
                  existing property.

                  Any Contributions or transfers directed to Real Estate
                  Separate Account which are deferred will instead be held in
                  our short term account, Separate Account LI, until a Valuation
                  Date when transfer to Real Estate Separate Account may be
                  made.

         5.       ORDER OF ENTRY. Since Real Estate Separate Account may not be
                  open on any given Valuation Date to accept all funds directed
                  by our customers to it, we have established the following
                  order of entry:

                  a)       All amounts held in Separate Account LI waiting for
                           transfer to Real Estate Separate Account.

                  b)       Any amounts held in any other Separate Account or in
                           our general account which are to be transferred to
                           Real Estate Separate Account.

                  Within each of the above two categories, funds will be
                  transferred one customer at a time, in order from the oldest
                  waiting request to the newest request. All amounts held in
                  Separate Account LI which are directed to Real Estate Separate
                  Account will be transferred before any funds are transferred
                  under Item (b).

                  Normally, either all or no part of an intended transfer under
                  this rider to Real Estate Separate Account will be made. If
                  the amount of the intended transfer is greater than the amount
                  open for acceptance by Real Estate Separate Account, the
                  entire amount of the transfer will continue to be held in
                  Separate Account LI until the Valuation Date


                                      -3-
<PAGE>   169
                  complete transfer may be made. However, we and the Member may
                  mutually agree to transfer only a portion of the intended
                  amount to Real Estate Separate Account.

                  We will notify you in writing when amounts have been
                  transferred to Real Estate Separate Account.

                  A Member may revoke his request for transfer of funds to Real
                  Estate Separate Account by giving us written notice prior to
                  the date transfer is made. The notice must also include new
                  investment directions for the intended transfer.

         6.       TRANSFERS AND PAYMENTS FROM THE SEPARATE INVESTMENT REAL
                  ESTATE FUND. We will. upon receipt of written request from you
                  and/or the Member, as permitted by the Plan,

                  a)       transfer to his General Investment Account or another
                           Separate Investment Account all or any portion of his
                           Separate Investment Real Estate Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of his Separate Investment Real Estate
                           Account, or

                  c)       pay to the Member an amount equal to all or any
                           portion of his Separate Investment Real Estate
                           Account.

                  The amount to be paid or transferred will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive your written request or
                  (ii) a later Valuation Date specified in your request, subject
                  to our right to defer a transfer or payment as described in
                  Item 7 of this rider. We are not responsible for the
                  application of amounts transferred to an Alternate Funding
                  Agent.

                  The amount transferred or paid will be deducted from the
                  Separate Investment Real Estate Account and will be an
                  application from such account as of the date transferred or
                  paid. Each transfer to another Separate Investment Account may
                  occur only on a Valuation Date of such Separate Investment
                  Account.

         7.       LIMITATIONS ON TRANSFERS FROM A SEPARATE INVESTMENT REAL
                  ESTATE ACCOUNT. In general, transfers and payments from a
                  Separate Investment Real Estate Account normally will be made
                  within seven business days after the Valuation Date specified
                  in Item 6. However, because of the illiquid nature of the
                  assets in which Real Estate Separate Account is invested, we
                  reserve the right to defer transfers or payments from a
                  Separate Investment Real Estate Account if a transfer or
                  payment would exceed the amount of cash and other liquid
                  assets held in Real Estate Separate Account, reduced by
                  amounts committed to purchase properties or needed for
                  operating expenses. Real Estate Separate Account may be
                  illiquid for indefinite periods of time because we do not
                  intend to sell properties to meet requests for transfer or
                  payment. Real Estate Separate Account will not be managed to
                  provide a liquidity pool for expected, but not yet received,
                  requests for transfer or payment.

                  If requests for transfer or payment from Real Estate Separate
                  Account are deferred, then the deferred transfers or payments,
                  when made, will be made in the following order:

                  a)       Any death benefits payable under a defined
                           contribution plan.


                                      -4-
<PAGE>   170
                  b)       All other requests for transfer or payment.

                  All death benefit payments from defined contribution plans
                  will be made before any other requests for transfer or
                  payment. Once these death benefits have been paid, other
                  requests will be paid in order of the dates we received the
                  requests.

                  Deferred transfers or payments, When paid, will be made as of
                  a Valuation Date and will be based on the Real Estate Separate
                  Account Unit Value as of the date paid.

SEPARATE INVESTMENT RIDER
BOND EMPHASIS BALANCED SEPARATE ACCOUNT

This rider is added to the Group Annuity Contract issued by us of which it is a
part. All terms defined in the contract and any of its attached riders have the
same meaning where used in this rider.

The purpose of this rider is to allow this contract to participate in our
balanced account called Bond Emphasis Balanced Separate Account.

The effective date of this rider is the latest of the Contract Date, the date
this rider has been approved for use in the state of issue, or the date stated
in the amendment adding it to the contract.

Pursuant to Article II, Section 6, the following is added to the contract:

         1.       BOND EMPHASIS BALANCED SEPARATE ACCOUNT. Bond Emphasis
                  Balanced Separate Account is a pooled Separate Account for use
                  by our retirement plan customers. It is invested by us in
                  other Separate Accounts established and maintained by us. The
                  majority of the assets will be invested in one or more of our
                  Separate Accounts invested primarily in bonds, mortgages,
                  commercial paper and other fixed income type investments. The
                  remainder of the assets of this Separate Account will be
                  invested in one or more of our Separate Accounts invested
                  primarily in common stocks and other equity investments. We
                  may also, at our option, occasionally invest in short term
                  money market instruments, cash or cash equivalents. We will
                  invest or reinvest the assets held in Bond Emphasis Balanced
                  Separate Account in accordance with applicable law, without
                  regard to any investment requirements of our general account
                  assets or of any investment requirements of our other Separate
                  Accounts.

                  The assets of Bond Emphasis Balanced Separate Account will pay
                  investment management charges under our other Separate
                  Accounts in which they are invested. An additional investment
                  management charge will be charged under this Separate Account
                  only for investment management services actually performed
                  exclusively for assets held in this Separate Account.
                  Currently no additional investment management charges are
                  assessed under this Separate Account. We reserve the right to
                  change the amount of the investment management charge at any
                  time by giving you written notice at least 30 days before the
                  date change is to take effect. In no event will the sum of the
                  investment management charges exceed 2.00% of the value of the
                  assets of Bond Emphasis Balanced Separate Account.

         2.       DETERMINING BOND EMPHASIS BALANCED SEPARATE ACCOUNT VALUE;
                  UNIT VALUES. The value of Bond Emphasis Balanced Separate
                  Account is the sum of the values of the assets of the Separate
                  Account. The assets of Bond Emphasis Balanced Separate Account
                  consist of amounts invested in other Separate Accounts
                  maintained by us. The value of the portion of the Bond
                  Emphasis Balanced Separate Account invested in any given
                  Separate Account will be the market value of the amount so
                  invested under the terms of the Separate Account in which it
                  is held. We will determine the value of Bond Emphasis Balanced
                  Separate Account on each Valuation Date.

                  The value of Bond Emphasis Balanced Separate Account may be
                  expressed in units. A Unit Value is the dollar value of one
                  unit held in Bond Emphasis Balanced Separate
<PAGE>   172
                  Account. We will determine the Unit Value of Bond Emphasis
                  Balanced Separate Account on each Valuation Date. The Unit
                  Value is equal to the market value of Bond Emphasis Balanced
                  Separate Account divided by the total number of Bond Emphasis
                  Balanced Separate Account Units on such date.

                  The initial Unit Value of one unit of Bond Emphasis Balanced
                  Separate Account was $10.00. The Unit Value for Contributions
                  or transfers added to Bond Emphasis Balanced Separate Account
                  after its date of inception will be the Unit Value of Bond
                  Emphasis Balanced Separate Account on the Valuation Date the
                  Contribution or transfer is accepted at our home office. If a
                  Contribution or transfer is received on any date other than a
                  Valuation Date, the Unit Value for such Contribution or
                  transfer will be determined on the next following Valuation
                  Date. On any Valuation Date occurring after its date of
                  inception, the Unit Value of Bond Emphasis Balanced Separate
                  Account will be equal to the market value of Bond Emphasis
                  Balanced Separate Account on such date divided by the number
                  of Bond Emphasis Balanced Separate Account Units before any
                  adjustments for Contributions or transfers to and applications
                  from Bond Emphasis Balanced Separate Account on such date.

         3.       BOND EMPHASIS BALANCED SEPARATE INVESTMENT ACCOUNT. A Bond
                  Emphasis Balanced Separate Investment Account is established
                  for each Member for each type of Contribution he directs to
                  Bond Emphasis Balanced Separate Account. The value of a Bond
                  Emphasis Balanced Separate Investment Account is its
                  proportionate share of the value of Bond Emphasis Balanced
                  Separate Account. This value will be determined in each
                  Valuation Date by multiplying (a) by (b):

                  a)       The number of Bond Emphasis Balanced Separate Account
                           Units in the Bond Emphasis Balanced Separate
                           Investment Account as of the Valuation Date.

                  b)       The Bond Emphasis Balanced Separate Account Unit
                           Value as of the Valuation Date, as determined in Item
                           2 of this rider.

                  Contributions or transfers to a Bond Emphasis Balanced
                  Separate Investment Account increase the number of Bond
                  Emphasis Balanced Separate Account Units credited to it;
                  applications from the account reduce the number of units. This
                  increase or decrease is determined by dividing the amount to
                  be credited to or applied from the account by the Bond
                  Emphasis Balanced Separate Account Unit Value on the Valuation
                  Date on which a Contribution or transfer was credited or an
                  application was made.

         4.       TRANSFERS FROM A BOND EMPHASIS BALANCED SEPARATE INVESTMENT
                  ACCOUNT. We will, upon receipt of Notification from you and/or
                  a Member, as the Plan permits,

                  a)       transfer to his General Investment Account all or any
                           portion of his Bond Emphasis Balanced Separate
                           investment Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of his Bond Emphasis Balanced Separate
                           Investment Account, or

                  c)       pay the Member an amount equal to all or any portion
                           of his Bond Emphasis Balanced Separate Investment
                           Account.

<PAGE>   173
                  The amount to be paid or transferred will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive the Notification or (ii) a
                  later Valuation Date specified in the request, subject to our
                  right to defer a transfer or payment as described in Item 5 of
                  this rider. We are not responsible for the application of
                  amounts transferred to an Alternate Funding Agent.

         5.       LIMITATIONS ON TRANSFERS AND PAYMENTS FROM A BOND EMPHASIS
                  BALANCED SEPARATE INVESTMENT ACCOUNT. In general, transfers
                  and payments from the Bond Emphasis Balanced Separate
                  Investment Account will be made within seven business days
                  after the Valuation Date specified in Item 4. We reserve the
                  right, however, to defer such transfers for a period not to
                  exceed 270 days.

                  However, if in the 36-month period which ends on the requested
                  date of transfer, all transfers and payments from the total of
                  all Bond Emphasis Balanced Separate Investment Accounts '
                  total $20,000,000 or more, then we reserve the right to make
                  the portion of the requested transfer or payment in excess of
                  $20,000,000 in substantially equal installments over a period
                  not to exceed 36 months. For purposes of this limitation,
                  transfers and payments from any separate investment accounts
                  or funds under other contracts included in Bond Emphasis
                  Balanced Separate Account in connection with the Plan or with
                  any other retirement plan of the Employer will be included as
                  a transfer or payment from a Bond Emphasis Balanced Separate
                  Investment Account. If this limitation is imposed by us, the
                  first installment will be made one month after the date of
                  request, or on such later date specified by you.

                  These limitations will not apply to payments to the
                  beneficiary of a Member.

                  If we defer transfer or payment under this Item 5, we will
                  determine the amount to be transferred or paid on the date
                  transfer or payment occurs. In such a case, a Member's Bond
                  Emphasis Balanced Separate Investment Account will continue to
                  participate in the Bond Emphasis Balanced Separate Account
                  until the date transfer or payment occurs. We will notify you
                  in the event of any deferment of more than 30 days under the
                  provisions of this Item 5.

SEPARATE INVESTMENT RIDER

STOCK EMPHASIS BALANCED SEPARATE ACCOUNT

This rider is added to the Group Annuity Contract issued by us of which it is a
part. All terms defined in the contract and any of its attached riders have the
same meaning where used in this rider.

The purpose of this rider is to allow this contract to participate in our
balanced account called Stock Emphasis Balanced Separate Account.

The effective date of this rider is the latest of the Contract Date, the date
this rider has been approved for use in the state of issue, or the date stated
in the amendment adding it to the contract.

Pursuant to Article II, Section 6, the following is added to the contract:

         1.       STOCK EMPHASIS BALANCED SEPARATE ACCOUNT. Stock Emphasis
                  Balanced Separate Account is a pooled Separate Account for use
                  by our retirement plan customers. It is invested by us in
                  other Separate Accounts established and maintained by us. The
                  majority of it is invested in one or more of our Separate
                  Accounts invested primarily in common stocks and other equity
                  investments. The remainder of the assets of this Separate
                  Account will be invested in one or more of our Separate
                  Accounts invested primarily in bonds, mortgages, commercial
                  paper and other fixed income type investments. We may also, at
                  our option, occasionally invest in short term money market
                  instruments, cash or cash equivalents. We will invest or
                  reinvest the assets held in the Stock Emphasis Balanced
                  Separate Account in accordance with applicable law, without
                  regard to any investment requirements of our general account
                  assets or of any investment requirements of our other Separate
                  Accounts.

                  The assets of Stock Emphasis Balanced Separate Account will
                  pay investment management charges under our other Separate
                  Accounts in which they are invested. An additional investment
                  management charge will be charged under this Separate Account
                  only for investment management services actually performed
                  exclusively for assets held in this Separate Account.
                  Currently, no additional investment management charges are
                  assessed under this Separate Account. We reserve the right to
                  change the amount of the investment management charge at any
                  time by giving you written notice at least 30 days before the
                  date change is to take effect. In no event will the sum of the
                  investment management charges exceed 2.00% of the value of the
                  assets of Stock Emphasis Balanced Separate Account.

         2.       DETERMINING STOCK EMPHASIS BALANCED SEPARATE ACCOUNT VALUE;
                  UNIT VALUES. The value of Stock Emphasis Balanced Separate
                  Account is the sum of the values of the assets of the Separate
                  Account. The assets of Stock Emphasis Balanced Separate
                  Account consist of amounts invested in other Separate Accounts
                  maintained by us. The value of the portion of the Stock
                  Emphasis Balanced Separate Account invested in any given
                  Separate Account will be the market value of the amount so
                  invested under the terms of the Separate Account in which it
                  is held. We will determine the value of Stock Emphasis
                  Balanced Separate Account on each Valuation Date.

                  The value of Stock Emphasis Balanced Separate Account may be
                  expressed in units. A Unit Value is the dollar value of one
                  unit held in Stock Emphasis Balanced Separate
<PAGE>   175
                  Account. We will determine the Unit Value of Stock Emphasis
                  Balanced Separate Account on each Valuation Date. The Unit
                  Value is equal to the market value of Stock Emphasis Balanced
                  Separate Account divided by the total number of Stock Emphasis
                  Balanced Separate Account Units on such date.

                  The initial Unit Value of one unit of Stock Emphasis Balanced
                  Separate Account was $10.00. The Unit Value for Contributions
                  or transfers added to Stock Emphasis Balanced Separate Account
                  after its date of inception will be the Unit Value of Stock
                  Emphasis Balanced Separate Account on the Valuation Date the
                  Contribution or transfer is accepted at our home office. If a
                  Contribution or transfer is received on any date other than a
                  Valuation Date, the Unit Value for such Contribution or
                  transfer will be determined on the next following Valuation
                  Date. On any Valuation Date occurring after its date of
                  inception, the Unit Value of Stock Emphasis Balanced Separate
                  Account will be equal to the market value of Stock Emphasis
                  Balanced Separate Account on such date divided by the number
                  of Stock Emphasis Balanced Separate Account Units before any
                  adjustments for Contributions or transfers to and applications
                  from Stock Emphasis Balanced Separate Account on such date.

         3.       STOCK EMPHASIS BALANCED SEPARATE INVESTMENT ACCOUNT. A Stock
                  Emphasis Balanced Separate Investment Account is established
                  for each Member for each type of Contribution he directs to
                  Stock Emphasis Balanced Separate Account. The value of a Stock
                  Emphasis Balanced Separate Investment Account is its
                  proportionate share of the value of Stock Emphasis Balanced
                  Separate Account. This value will be determined on each
                  Valuation Date by multiplying (a) by (b):

                  a)       The number of Stock Emphasis Balanced Separate
                           Account Units in the Stock Emphasis Balanced Separate
                           Investment Account as of the Valuation Date.

                  b)       The Stock Emphasis Balanced Separate Account Unit
                           Value as of the Valuation Date, as determined in Item
                           2 of this rider.

                  Contributions or transfers to a Stock Emphasis Balanced
                  Separate Investment Account increase the number of Stock
                  Emphasis Balanced Separate Account Units credited to it;
                  applications from the account reduce the number of units. This
                  increase or decrease is determined by dividing the amount to
                  be credited to or applied from the account by the Stock
                  Emphasis Balanced Separate Account Unit Value on the Valuation
                  Date on which a Contribution or transfer was credited or an
                  application was made.

         4.       TRANSFERS FROM A STOCK EMPHASIS BALANCED SEPARATE INVESTMENT
                  ACCOUNT. We will, upon receipt of Notification from you and/or
                  a Member, as the Plan permits,

                  a)       transfer to his General Investment Account all or any
                           portion of his Stock Emphasis Balanced Separate
                           Investment Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of his Stock Emphasis Balanced Separate
                           Investment Account, or

                  c)       pay the Member an amount equal to all or any portion
                           of his Stock Emphasis Balanced Separate Investment
                           Account.


                                      -2-
<PAGE>   176
                  The amount to be paid or transferred will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive the Notification or (ii) a
                  later Valuation Date specified in the request, subject to our
                  right to defer a transfer or payment as described in Item 5 of
                  this rider. We are not responsible for the application of
                  amounts transferred to an Alternate Funding Agent.

                  The amount transferred or paid will be deducted from the Stock
                  Emphasis Balanced Separate Investment Account and will be an
                  application from such account as of the date transferred or
                  paid. Each transfer to another Separate Investment Account may
                  occur only on a Valuation Date of such Separate Investment
                  Account.

         5.       LIMITATIONS ON TRANSFERS FROM A STOCK EMPHASIS BALANCED
                  SEPARATE INVESTMENT ACCOUNT. In general, transfers and
                  payments from the Stock Emphasis Balanced Separate Investment
                  Account will be made within seven business days after the
                  Valuation Date specified in Item 4. We reserve the right,
                  however, to defer such transfers for a period not to exceed
                  270 days.

                  However, if in the 36-month period which ends on the requested
                  date of transfer, all transfers and payments from the total of
                  all Stock Emphasis Balanced Separate Investment Accounts total
                  $20,000,000 or more, then we reserve the right to make the
                  portion of the requested transfer or payment in excess of
                  $20,000,000 in substantially equal installments over a period
                  not to exceed 36 months. For purposes of this limitation,
                  transfers and payments from any separate investment accounts
                  or funds under other contracts included in Stock Emphasis
                  Balanced Separate Account in connection with the Plan or with
                  any other retirement plan of the Employer will be included as
                  a transfer or payment from a Stock Emphasis Balanced Separate
                  Investment Account. If this limitation is imposed by us, the
                  first installment will be made one month after the date of
                  request, or on such later date specified by you.

                  These limitations will not apply to payments to the
                  beneficiary of a Member.

                  If we defer transfer or payment under this Item 5, we will
                  determine the amount to be transferred or paid on the date
                  transfer or payment occurs. In such a case, a Member's all
                  Stock Emphasis Balanced Separate Investment Account will
                  continue to participate in the Stock Emphasis Balanced
                  Separate Account until the date transfer or payment occurs. We

SEPARATE INVESTMENT RIDER

GOVERNMENT SECURITIES SEPARATE ACCOUNT

This rider is added to the Group Annuity Contract issued by us of which it is a
part. All terms defined in the contract and any of its attached riders have the
same meaning where used in this rider.

The purpose of this rider is to allow the contract to participate in our fixed
income account called Government Securities Separate Account.

The effective date of this rider is the latest of the Contract Date, the date
this rider has been approved for use in the state of issue, or the date stated
in the amendment adding it to the contract.

Pursuant to Article II, Section 6, the following is added to the contract.

         1.       GOVERNMENT SECURITIES SEPARATE ACCOUNT. Government Securities
                  Separate Account is a pooled Separate Account for use by our
                  retirement plan customers. It is invested by us primarily in
                  obligations issued or guaranteed by agencies and
                  instrumentalities of the United States Government including,
                  but not limited to, Government National Mortgage Association,
                  Federal National Mortgage Association, Federal Home Loan
                  Mortgage Association and Student Loan Marketing Association.
                  In addition, we may invest in direct obligations of the U.S.
                  Treasury such as notes, bonds, and bills. We may also invest
                  in short term money market instruments, cash or cash
                  equivalents. We will invest and reinvest the assets held in
                  Government Securities Separate Account in accordance with
                  applicable law, without regard to any investment requirements
                  of our general account assets or any of our other Separate
                  Accounts.

                  The investment management charge under Government Securities
                  Separate Account is based on the value of its assets. The
                  pro-rata charge for investment management will be deducted
                  from Government Securities Separate Account on each Valuation
                  Date for the number of calendar days within the Valuation
                  Period ending on such Valuation Date.

                  The annual investment management charge for Government
                  Securities Separate Account will not at any time exceed 2.00%
                  of the value of its assets. Currently, the annual investment
                  management charge for Government Securities Separate Account
                  is 0.45% of the value of its assets. We reserve the right to
                  change the amount of charge for investment management up to
                  the 2.00% limit at any time by giving you written notice at
                  least 30 days before the date the change is to take effect.

         2.       DETERMINING GOVERNMENT SECURITIES SEPARATE ACCOUNT VALUE; UNIT
                  VALUES. The value of Government Securities Separate Account is
                  its market value. If there is no readily ascertainable market
                  value, its value is the fair value of the assets held in such
                  Separate Account, as determined by us using generally accepted
                  accounting practices and applicable law. We will determine the
                  value of Government Securities Separate Account on each
                  Valuation Date.

                  The value of Government Securities Separate Account will be
                  expressed in units. A Unit Value is the dollar value of one
                  unit held in Government Securities Separate Account. We will
                  determine the Unit Value of Government Securities Separate
                  Account on each Valuation Date. This Unit Value is equal to
                  the market value of Government Securities
<PAGE>   178
                  Separate Account divided by the total number of Government
                  Securities Separate Account Units on such date.

                  The initial Unit Value of one unit of Government Securities
                  Separate Account was $10.00. The Unit Value for Contributions
                  or transfers added to Government Securities Separate Account
                  after its date of inception will be the Unit Value of
                  Government Securities Separate Account on the Valuation Date
                  the Contribution or transfer is accepted by us at our home
                  office. If a Contribution or transfer is received on any date
                  other than a Valuation Date, the Unit Value for such
                  Contribution or transfer will be determined on the next
                  following Valuation Date. On any Valuation Date occurring
                  after its date of inception, the Unit Value of Government
                  Securities Separate Account will be equal to the market value
                  of Government Securities Separate Account on such date divided
                  by the number of Government Securities Separate Account Units
                  before any adjustments for Contributions or transfers to and
                  applications from Government Securities Separate Account on
                  such date.

         3.       GOVERNMENT SECURITIES SEPARATE INVESTMENT ACCOUNT. A
                  Government Securities Separate Investment Account is
                  established for each Member for each type of Contribution he
                  directs to Government Securities Separate Account. The value
                  of a Government Securities Separate Investment Account is its
                  proportionate share of the value of Government Securities
                  Separate Account. This value will be determined on each
                  Valuation Date by multiplying (a) by (b):

                  a)       The number of Government Securities Separate Account
                           Units in the Government Securities Separate
                           Investment Account as of the Valuation Date.

                  b)       The Government Securities Separate Account Unit Value
                           as of the Valuation Date, as determined in Item 2 of
                           this rider.

                  Contributions or transfers to a Government Securities Separate
                  Investment Account increase the number of Government
                  Securities Separate Account Units credited to it; applications
                  from the account reduce the number of units. This increase or
                  decrease is determined by dividing the amount to be credited
                  to or applied from the account by the Government Securities
                  Separate Account Unit Value on the Valuation Date on which a
                  Contribution or transfer was credited or an application was
                  made.

         4.       TRANSFERS FROM A GOVERNMENT SECURITIES SEPARATE INVESTMENT
                  ACCOUNT. We will, upon receipt of Notification from you and/or
                  a Member, as the Plan permits,

                  a)       transfer to his General Investment Account all or any
                           portion of his Government Securities Separate
                           investment Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of his Government Securities Separate
                           Investment Account, or

                  c)       pay the Member an amount equal to all or any portion
                           of his Government Securities Separate Investment
                           Account.

                  The amount to be paid or transferred will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive the Notification or


                                      -2-
<PAGE>   179
                  (ii) a later Valuation Date specified in the request, subject
                  to our right to defer a transfer or payment as described in
                  Item 5 of this rider. We are not responsible for the
                  application of amounts transferred to an Alternate Funding
                  Agent.

                  The amount transferred or paid will be deducted from the
                  Government Securities Separate Investment Account and will be
                  an application from such account as of the date transferred or
                  paid. Each transfer to another Separate Investment Account may
                  occur only on a Valuation Date of such Separate Investment
                  Account.

         5.       LIMITATIONS ON TRANSFERS AND PAYMENTS FROM A GOVERNMENT
                  SECURITIES SEPARATE INVESTMENT ACCOUNT. In general, transfers
                  and payments from the Government Securities Separate
                  Investment Account will be made within seven business days
                  after the Valuation Date specified in Item 4. We reserve the
                  right, however, to defer such transfers for a period not to
                  exceed 90 days.

                  These limitations will not apply to payments to the
                  beneficiary of a Member.

                  If we defer transfer or payment under this Item 5, we will
                  determine the amount to be transferred or paid on the date
                  transfer or payment occurs. In such a case, a Members
                  Government Securities Separate Investment Account will
                  continue to participate in the Government Securities Separate
                  Account until the date transfer or payment occurs. We will
                  notify you in the event of any deferment of more than 30 days
                  under the provisions of this Item 5.

SEPARATE INVESTMENT RIDER

GROWTH STOCK SEPARATE ACCOUNT

This rider is added to the Group Annuity Contract issued by us of which it is a
part. All terms defined in the contract and any of its attached riders have the
same meaning where used in this rider.

The purpose of this rider is to allow the contract to participate in our stock
account called Growth Stock Separate Account.

The effective date of this rider is the latest of the Contract Date, the date
this rider has been approved for use in the state of issue, or the date stated
in the amendment adding it to the contract.

Pursuant to Article II, Section 6, the following is added to the contract.

         1.       GROWTH STOCK SEPARATE ACCOUNT. Growth Stock Separate Account
                  is a pooled Separate Account for use by our retirement plan
                  customers. It is invested by us primarily in common stocks,
                  derivative instruments such as options and futures, other
                  equity securities, or other convertible securities that may be
                  converted to common stocks. The investments to be considered
                  generally will be from large, established companies whose
                  earnings are expected to grow at above average rates. We may
                  also, at our option, occasionally invest in short term money
                  market instruments, cash or cash equivalents. We will invest
                  and reinvest the assets held in Growth Stock Separate Account
                  in accordance with applicable law, without regard to any
                  investment requirements of our general account assets or any
                  of our other Separate Accounts.

                  The investment management charge under Growth Stock Separate
                  Account is based on the value of its assets. The pro-rata
                  charge for investment management will be deducted from Growth
                  Stock Separate Account on each Valuation Date for the number
                  of calendar days within the Valuation Period ending on such
                  Valuation Date.

                  The annual investment management charge for Growth Stock
                  Separate Account will not at any time exceed 2.00% of the
                  value of its assets. Currently, the annual investment
                  management charge for Growth Stock Separate Account is 0.45%
                  of the value of its assets. We reserve the right to change the
                  amount of charge for investment management up to the 2.00%
                  limit at any time by giving you written notice at least 30
                  days before the date the change is to take effect.

         2.       DETERMINING GROWTH STOCK SEPARATE ACCOUNT VALUE; UNIT VALUES.
                  The value of Growth Stock Separate Account is its market
                  value. If there is no readily ascertainable market value, its
                  value is the fair value of the assets held in such Separate
                  Account, as determined by us using generally accepted
                  accounting practices and applicable law. We will determine the
                  value of Growth Stock Separate Account on each Valuation Date.

                  The value of Growth Stock Separate Account will be expressed
                  in units. A Unit Value is the dollar value of one unit held in
                  Growth Stock Separate Account. We will determine the Unit
                  Value of Growth Stock Separate Account on each Valuation Date.
                  This Unit Value is equal to the market value of Growth Stock
                  Separate Account divided by the total number of Growth Stock
                  Separate Account Units on such date.
<PAGE>   181
                  The initial Unit Value of one unit of Growth Stock Separate
                  Account was $10.00. The Unit Value for Contributions or
                  transfers added to Growth Stock Separate Account after its
                  date of inception will be the Unit Value of Growth Stock
                  Separate Account on the Valuation Date the Contribution or
                  transfer is accepted by us at our home office. If a
                  Contribution or transfer is received on any date other than a
                  Valuation Date, the Unit Value for such Contribution or
                  transfer will be determined on the next following Valuation
                  Date. On any Valuation Date occurring after its date of
                  inception, the Unit Value of Growth Stock Separate Account
                  will be equal to the market value of Growth Stock Separate
                  Account on such date divided by the number of Growth Stock
                  Separate Account Units before any adjustments for
                  Contributions or transfers to and applications from Growth
                  Stock Separate Account on such date.

         3.       GROWTH STOCK SEPARATE INVESTMENT ACCOUNT. A Growth Stock
                  Separate Investment Account is established for each Member for
                  each type of Contribution he directs to Growth Stock Separate
                  Account. The value of a Growth Stock Separate Investment
                  Account is its proportionate share of the value of Growth
                  Stock Separate Account. This value will be determined on each
                  Valuation Date by multiplying (a) by (b):

                  a)       The number of Growth Stock Separate Account Units in
                           the Growth Stock Separate Investment Account as of
                           the Valuation Date.

                  b)       The Growth Stock Separate Account Unit Value as of
                           the Valuation Date, as determined in Item 2 of this
                           rider.

                  Contributions or transfers to a Growth Stock Separate
                  Investment Account increase the number of Growth Stock
                  Separate Account Units credited to it; applications from the
                  account reduce the number of units. This increase or decrease
                  is determined by dividing the amount to be credited to or
                  applied from the account by the Growth Stock Separate Account
                  Unit Value on the Valuation Date on which a Contribution or
                  transfer was credited or an application was made.

         4.       TRANSFERS FROM A GROWTH STOCK SEPARATE INVESTMENT ACCOUNT. We
                  will, upon receipt of Notification from you and/or a Member,
                  as the Plan permits,

                  a)       transfer to his General Investment Account all or any
                           portion of his Growth Stock Separate Investment
                           Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of his Growth Stock Separate Investment
                           Account, or

                  c)       pay the Member an amount equal to all or any portion
                           of his Growth Stock Separate Investment Account.

                  The amount to be paid or transferred will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive the Notification or (ii) a
                  later Valuation Date specified in the request, subject to our
                  right to defer a transfer or payment as described in Item 5 of
                  this rider. We are not responsible for the application of
                  amounts transferred to an Alternate Funding Agent.


                                      -2-
<PAGE>   182
                  The amount transferred or paid will be deducted from the
                  Growth Stock Separate Investment Account and will be an
                  application from such account as of the date transferred or
                  paid. Each transfer to another Separate Investment Account may
                  occur only on a Valuation Date of such Separate Investment
                  Account.

         5.       LIMITATIONS ON TRANSFERS AND PAYMENTS FROM A GROWTH STOCK
                  SEPARATE INVESTMENT ACCOUNT. In general, transfers and
                  payments from the Growth Stock Separate Investment Account
                  will be made within seven business days after the Valuation
                  Date specified in Item 4. We reserve the right, however, to
                  defer such transfers for a period not to exceed 270 days.

                  However, if in the 36-month period which ends on the requested
                  date of transfer, all transfers and payments from the total of
                  all Growth Stock Separate Investment Accounts total
                  $20,000,000 or more, then we reserve the right to make the
                  portion of the requested transfer or payment in excess of
                  $20,000,000 in substantially equal installments over a period
                  not to exceed 36 months. For purposes of this limitation,
                  transfers and payments from any separate investment accounts
                  or funds under other contracts included in Growth Stock
                  Separate Account in connection with the Plan or with any other
                  retirement plan of the Employer will be included as a transfer
                  or payment from a Growth Stock Separate Investment Account. If
                  this limitation is imposed by us, the first installment will
                  be made one month after the date of request, or on such later
                  date specified by you.

                  These limitations will not apply to payments to the
                  beneficiary of a Member.

                  If we defer transfer or payment under this Item 5, we will
                  determine the amount to be transferred or paid on the date
                  transfer or payment occurs. In such a case, a Member's Growth
                  Stock Separate Investment Account will continue to participate
                  in the Growth Stock Separate Account until the date transfer
                  or payment occurs. We will notify you in the event of any
                  deferment of more than 30 days under the provisions of this
                  Item 5.

SEPARATE INVESTMENT RIDER

SMALL COMPANY STOCK SEPARATE ACCOUNT

This rider is added to the Group Annuity Contract issued by us of which it is a
part. All terms defined in the contract and any of its attached riders have the
same meaning where used in this rider.

The purpose of this rider is to allow the contract to participate in our stock
account called Small Company Stock Separate Account.

The effective date of this rider is the latest of the Contract Date, the date
this rider has been approved for use in the state of issue, or the date stated
in the amendment adding it to the contract.

Pursuant to Article II, Section 6, the following is added to the contract.

         1.       SMALL COMPANY STOCK SEPARATE ACCOUNT. Small Company Stock
                  Separate Account is a pooled Separate Account for use by our
                  retirement plan customers. It is invested by us primarily in
                  common stocks, derivative instruments such as options and
                  futures, other equity securities, or other convertible
                  securities that may be converted to common stocks. The
                  investments to be considered generally will be from U.S.
                  companies that are smaller than the 500 largest U.S. companies
                  and whose earnings are expected to grow at above average
                  rates. We may also, at our option, occasionally invest in
                  short term money market instruments, cash or cash equivalents.
                  We will invest and reinvest the assets held in Small Company
                  Stock Separate Account in accordance with applicable law,
                  without regard to any investment requirements of our general
                  account assets or any of our other Separate Accounts.

                  The investment management charge under Small Company Stock
                  Separate Account is based on the value of its assets. The
                  pro-rata charge for investment management will be deducted
                  from Small Company Stock Separate Account on each Valuation
                  Date for the number of calendar days within the Valuation
                  Period ending on such Valuation Date.

                  The annual investment management charge for Small Company
                  Stock Separate Account will not at any time exceed 2.00% of
                  the value of its assets. Currently, the annual investment
                  management charge for Small Company Stock Separate Account is
                  0.45% of the value of its assets. We reserve the right to
                  change the amount of charge for investment management up to
                  the 2.00% limit at any time by giving you written notice at
                  least 30 days before the date the change is to take effect.

         2.       DETERMINING SMALL COMPANY STOCK SEPARATE ACCOUNT VALUE; UNIT
                  VALUES. The value of Small Company Stock Separate Account is
                  its market value. If there is no readily ascertainable market
                  value, its value is the fair value of the assets held in such
                  Separate Account, as determined by us using generally accepted
                  accounting practices and applicable law. We will determine the
                  value of Small Company Stock Separate Account on each
                  Valuation Date.

                  The value of Small Company Stock Separate Account will be
                  expressed in units. A Unit Value is the dollar value of one
                  unit held in Small Company Stock Separate Account. We will
                  determine the Unit Value of Small Company Stock Separate
                  Account on each Valuation Date. This Unit Value is equal to
                  the market value of Small Company Stock
<PAGE>   184
                  Separate Account divided by the total number of Small Company
                  Stock Separate Account Units on such date.

                  The initial Unit Value of one unit of Small Company Stock
                  Separate Account was $10.00. The Unit Value for Contributions
                  or transfers added to Small Company Stock Separate Account
                  after its date of inception will be the Unit Value of Small
                  Company Stock Separate Account on the Valuation Date the
                  Contribution or transfer is accepted by us at our home office.
                  If a Contribution or transfer is received on any date other
                  than a Valuation Date, the Unit Value for such Contribution or
                  transfer will be determined on the next following Valuation
                  Date. On any Valuation Date occurring after its date of
                  inception, the Unit Value of Small Company Stock Separate
                  Account will be equal to the market value of Small Company
                  Stock Separate Account on such date divided by the number of
                  Small Company Stock Separate Account Units before any
                  adjustments for Contributions or transfers to and applications
                  from Small Company Stock Separate Account on such date.

         3.       SMALL COMPANY STOCK SEPARATE INVESTMENT ACCOUNT. A Small
                  Company Stock Separate Investment Account is established for
                  each Member for each type of Contribution he directs to Small
                  Company Stock Separate Account. The value of a Small Company
                  Stock Separate Investment Account is its proportionate share
                  of the value of Small Company Stock Separate Account. This
                  value will be determined on each Valuation Date by multiplying
                  (a) by (b):

                  a)       The number of Small Company Stock Separate Account
                           Units in the Small Company Stock Separate Investment
                           Account as of the Valuation Date.

                  b)       The Small Company Stock Separate Account Unit Value
                           as of the Valuation Date, as determined in Item 2 of
                           this rider.

                  Contributions or transfers to a Small Company Stock Separate
                  Investment Account increase the number of Small Company Stock
                  Separate Account Units credited to it; applications from the
                  account reduce the number of units. This increase or decrease
                  is determined by dividing the amount to be credited to or
                  applied from the account by the Small Company Stock Separate
                  Account Unit Value on the Valuation Date on which a
                  Contribution or transfer was credited or an application was
                  made.

         4.       TRANSFERS FROM A SMALL COMPANY STOCK SEPARATE INVESTMENT
                  ACCOUNT. We will, upon receipt of Notification from you and/or
                  a Member, as the Plan permits,

                  a)       transfer to his General Investment Account all or any
                           portion of the Small Company Stock Separate
                           Investment Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of his Small Company Stock Separate
                           Investment Account, or

                  c)       pay the Member an amount equal to all or any portion
                           of his Small Company Stock Separate Investment
                           Account.

                  The amount to be paid or transferred will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive the Notification or


                                      -2-
<PAGE>   185
                  (ii) a later Valuation Date specified in the request, subject
                  to our right to defer a transfer or payment as described in
                  Item 5 of this rider. We are not responsible for the
                  application of amounts transferred to an Alternate Funding
                  Agent.

                  The amount transferred or paid will be deducted from the Small
                  Company Stock Separate Investment Account and will be an
                  application from such account as of the date transferred or
                  paid. Each transfer to another Separate Investment Account may
                  occur only on a Valuation Date of such Separate Investment
                  Account.

         5.       LIMITATIONS ON TRANSFERS AND PAYMENTS FROM A SMALL COMPANY
                  STOCK SEPARATE INVESTMENT ACCOUNT. In general, transfers and
                  payments from the Small Company Stock Separate Investment
                  Account will be made within seven business days after the
                  Valuation Date specified in Item 4. We reserve the right,
                  however, to defer such transfers or payments for a period not
                  to exceed 270 days.

                  However, if in the 36-month period which ends on the requested
                  date of transfer, all transfers and payments from the total of
                  all Small Company Stock Separate Investment Accounts total
                  $20,000,000 or more, then we reserve the right to make the
                  portion of the requested transfer or payment in excess of
                  $20,000,000 in substantially equal installments over a period
                  not to exceed 36 months. For purposes of this limitation,
                  transfers and payments from any separate investment accounts
                  or funds under other contracts included in Small Company Stock
                  Separate Account in connection with the Plan or with any other
                  retirement plan of the Employer will be included as a transfer
                  or payment from a Small Company Stock Separate Investment
                  Account. If this limitation is imposed by us, the first
                  installment will be made one month after the date of request,
                  or on such later date specified by you.

                  These limitations will not apply to payments to the
                  beneficiary of a Member.

                  If we defer transfer or payment under this Item 5, we will
                  determine the amount to be transferred or paid on the date
                  transfer or payment occurs. In such a case, a Member's all
                  Small Company Stock Separate Investment Account will continue
                  to participate in the Small Company Stock Separate Account
                  until the date transfer or payment occurs. We will notify you
                  in the event of any deferment of more than 30 days under the
                  provisions of this Item 5.

SEPARATE INVESTMENT RIDER

VALUE STOCK SEPARATE ACCOUNT

This rider is added to the Group Annuity Contract issued by us of which it is a
part. All terms defined in the contract and any of its attached riders have the
same meaning where used in this rider.

The purpose of this rider is to allow the contract to participate in our stock
account called Value Stock Separate Account.

The effective date of this rider is the latest of the Contract Date, the date
this rider has been approved for use in the state of issue, or the date stated
in the amendment adding it to the contract.

Pursuant to Article II, Section 6, the following is added to the contract:

         1.       VALUE STOCK SEPARATE ACCOUNT. Value Stock Separate Account is
                  a pooled Separate Account for use by our retirement plan
                  customers. It is invested by us primarily in common stocks.
                  derivative instruments such as options and futures, other
                  equity securities, or other convertible securities that may be
                  converted to common stocks, which we view as undervalued by
                  the market. The investments to be considered generally will be
                  from financially stable companies and will have below-average
                  price/earnings ratios with above-average dividend yields. We
                  may also, at our option, occasionally invest in short term
                  money market instruments, cash or cash equivalents. If, in our
                  opinion, the market as a whole is overvalued, we may hold
                  assets of this account in fixed income securities instead of
                  stocks. We will invest and reinvest the assets held in Value
                  Stock Separate Account in accordance with applicable law,
                  without regard to any investment requirements of our general
                  account assets or any of our other Separate Accounts.

                  The investment management charge under Value Stock Separate
                  Account is based on the value of its assets. The pro-rata
                  charge for investment management will be deducted from Value
                  Stock Separate Account on each Valuation Date for the number
                  of calendar days within the Valuation Period ending on such
                  Valuation Date.

                  The annual investment management charge for Value Stock
                  Separate Account will hot at any time exceed 2.00% of the
                  value of its assets. Currently, the annual investment
                  management charge for Value Stock Separate Account is 0.45% of
                  the value of its assets. We reserve the right to change the
                  amount of charge for investment management up to the 2.00%
                  limit at any time by giving you written notice at least 30
                  days before the date the change is to take effect.

         2.       DETERMINING VALUE STOCK SEPARATE ACCOUNT VALUE; UNIT VALUES.
                  The value of Value Stock Separate Account is its market value.
                  If there is no readily ascertainable market value, its value
                  is the fair value of the assets held in such Separate Account,
                  as determined by us using generally accepted accounting
                  practices and applicable law. We will determine the value of
                  Value Stock Separate Account on each Valuation Date.

                  The value of Value Stock Separate Account will be expressed in
                  units. A Unit Value is the dollar value of one unit held in
                  Value Stock Separate Account. We will determine the Unit Value
                  of Value Stock Separate Account on each Valuation Date. This
                  Unit Value is
<PAGE>   187
                  equal to the market value of Value Stock Separate Account
                  divided by the total number of Value Stock Separate Account
                  Units on such date.

                  The initial Unit Value of one unit of Value Stock Separate
                  Account was $10.00. The Unit Value for Contributions or
                  transfers added to Value Stock Separate Account after its date
                  of inception will be the Unit Value of Value Stock Separate
                  Account on the Valuation Date the Contribution or transfer is
                  accepted by us at our home office. If a Contribution or
                  transfer is received on any date other than a Valuation Date,
                  the Unit Value for such Contribution or transfer will be
                  determined on the next following Valuation Date. On any
                  Valuation Date occurring after its date of inception, the Unit
                  Value of Value Stock Separate Account will be equal to the
                  market value of Value Stock Separate Account on such date
                  divided by the number of Value Stock Separate Account Units
                  before any adjustments for Contributions or transfers to and
                  applications from Value Stock Separate Account on such date.

         3.       VALUE STOCK SEPARATE INVESTMENT ACCOUNT. A Value Stock
                  Separate Investment Account is established for each Member for
                  each type of Contribution he directs to Value Stock Separate
                  Account. The value of a Value Stock Separate Investment
                  Account is its proportionate share of the value of Value Stock
                  Separate Account. This value will be determined on each
                  Valuation Date by multiplying (a) by (b):

                  a)       The number of Value Stock Separate Account Units in
                           the Value Stock Separate Investment Account as of the
                           Valuation Date.

                  b)       The Value Stock Separate Account Unit Value as of the
                           Valuation Date, as determined in Item 2 of this
                           rider.

                  Contributions or transfers to a Value Stock Separate
                  Investment Account increase the number of Value Stock Separate
                  Account Units credited to it; applications from the account
                  reduce the number of units. This increase or decrease is
                  determined by dividing the amount to be credited to or applied
                  from the account by the Value Stock Separate Account Unit
                  Value on the Valuation Date on which a Contribution or
                  transfer was credited or an application was made.

         4.       TRANSFERS FROM A VALUE STOCK SEPARATE INVESTMENT ACCOUNT. We
                  will, upon receipt of Notification from you and/or a Member,
                  as the Plan permits,

                  a)       transfer to his General Investment Account all or any
                           portion of his Value Stock Separate Investment
                           Account, or

                  b)       transfer to an Alternate Funding Agent all or any
                           portion of his Value Stock Separate Investment
                           Account, or

                  c)       pay the Member an amount equal to all or any portion
                           of his Value Stock Separate Investment Account.

                  The amount to be paid or transferred will be determined and
                  paid or transferred within seven business days after (i) the
                  Valuation Date on which we receive the Notification or (ii) a
                  later Valuation Date specified in the request, subject to our
                  right to defer a transfer


                                      -2-
<PAGE>   188
                  or payment as described in Item 5 of this rider. We are not
                  responsible for the application of amounts transferred to an
                  Alternate Funding Agent.

                  The amount transferred or paid will be deducted from the Value
                  Stock Separate Investment Account and will be an application
                  from such account as of the date transferred or paid. Each
                  transfer to another Separate Investment Account may occur only
                  on a Valuation Date of such Separate Investment Account.

         5.       LIMITATIONS ON TRANSFERS AND PAYMENTS FROM A VALUE STOCK
                  SEPARATE INVESTMENT ACCOUNT. In general, transfers and
                  payments from the Value Stock Separate Investment Account will
                  be made within seven business days after the Valuation Date
                  specified in Item 4. We reserve the right, however, to defer
                  such transfers or payments for a period not to exceed 270
                  days.

                  However, if in the 36-month period which ends on the requested
                  date of transfer, all transfers and payments from the total of
                  all Value Stock Separate Investment Accounts total $20,000,000
                  or more, then we reserve the right to make the portion of the
                  requested transfer or payment in excess of $20,000,000 in
                  substantially equal installments over a period not to exceed
                  36 months. For purposes of this limitation, transfers and
                  payments from any separate investment accounts or funds under
                  other contracts included in Value Stock Separate Account in
                  connection with the Plan or with any other retirement plan of
                  the Employer will be included as a transfer or payment from a
                  Value Stock Separate Investment Account. If this limitation is
                  imposed by us, the first installment will be made one month
                  after the date of request, or on such later date specified by
                  you.

                  These limitations will not apply to payments to the
                  beneficiary of a Member.

                  If we defer transfer or payment under this Item 5, we will
                  determine the amount to be transferred or paid on the date
                  transfer or payment occurs. In such a case, a Member's all
                  Value Stock Separate Investment Account will continue to
                  participate in the Value Stock Separate Account until the date
                  transfer or payment occurs. We will notify you in the event of
                  any deferment of more than 30 days under the provisions of
                  this Item 5.

                                                                   Exhibit 10.15


                                MANUFACTURING AND
                             DISTRIBUTION AGREEMENT

                  This Agreement is between Rockford Corporation, an Arizona
corporation ("Rockford"), and American Connection Incorporated, an Arizona
corporation ("ACI"). Rockford and ACI 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 ACI Business and Experience. ACI is an affiliate of Path
Group, Ltd., a British corporation ("Path"), and is a manufacturer and supplier
of accessory products that may be used by Rockford's customers in installation
of Rockford's own products.

                  1.3 Sales Relationship. Rockford and ACI desire to enter into
a relationship whereby ACI will manufacture or purchase, warehouse, and drop
ship accessory products (the "Products") to Rockford's dealers in the United
States. The Products covered by this Agreement are identified on Exhibit A,
attached hereto; the parties may at any time add other products to those
identified by executing an amendment to Exhibit A and, upon such action, such
products shall be treated for all purposes as "Products."

                  1.4 License. Rockford desires to license ACI to place certain
of its trademarks and tradenames (the "Names") on the Products, solely for sales
of the Products to Rockford's dealers in the United States. The Names are
identified on Exhibit B, which may be amended by the parties from time to time.

                  1.5 Purpose. The purpose of this Agreement is to state the
terms and conditions of the agreement between ACI and Rockford relating to sales
of the Products to Rockford's dealers in the United States.

         2. DISTRIBUTION OF THE PRODUCTS. ACI agrees to manufacture or purchase,
warehouse, and drop ship the Products to Rockford's dealers in the United
States, and Rockford agrees to solicit sales of the Products, on the following
basis:

                  2.1 Inventory. ACI shall manufacture or purchase the Products
and shall maintain an inventory of the Products at a location or locations in
the United States which shall be selected in consultation with Rockford. ACI
shall maintain inventory at a level that is sufficient to satisfy reasonably
expected demand for the Products. Representatives of Rockford and ACI shall meet
regularly to discuss anticipated demand for the Products and the level of
inventory appropriate to allow Rockford and ACI to meet that demand.

                  2.2 Solicitation of Sales. Rockford shall use its distribution
network and sales representatives to solicit sales of the Products to Rockford's
authorized dealers. Rockford may (but is not required to) use such sales methods
as it deems appropriate in connection with such
<PAGE>   2
solicitations, including dealer visits, telemarketing, direct mail, and
advertising. ACI shall not make any independent sales of the Products, but shall
(1) assist Rockford's sales staff and sales representatives in their efforts to
sell the Products, (2) make available (subject to reasonable budgetary
constraints established by ACI) to Rockford's dealers in the United States
approved point-of-purchase materials including product displays as agreed to by
Rockford from time to time, and (3) provide support as necessary in the form of
technical information or advisory personnel. Sales of the Products shall be
managed for all purposes so that dealers are encouraged to treat the Products as
Rockford products and to deal directly with Rockford on all matters related to
the Products.

                  2.3 Sales of Goods. ACI shall deliver the Products, to
Rockford's dealers in the United States, upon its receipt from Rockford of
dealer orders for the Products. Each order shall be shipped (subject to
availability), freight prepaid, to a Rockford dealer as directed by Rockford and
within one working day after Rockford delivers the order to ACI.

                  2.4 Price and Payment.

                           2.4.1 Price. ACI shall establish a dealer price and a
suggested retail price for each Product. Rockford shall sell the Products to its
dealers at the dealer price suggested by ACI, subject to payment, volume, and
other sales incentives established by Rockford that are either (a) no more than
(Confidential material redacted and filed separately with the Commission) of the
dealer price suggested by ACI or (b) approved by ACI (the dealer price
established by ACI less such discounts is the "Net Dealer Price"). Rockford
shall recommend that its dealers sell the products at the suggested retail price
established by ACI.

                           2.4.2 Payments by Dealers and Credit Risk. Rockford
shall be solely responsible for collecting from its dealers all amounts due for
all sales of Products to such dealers. ACI shall deliver to Rockford bills of
lading or other shipment records promptly after it ships each order so that
Rockford may properly invoice its dealers. Rockford is responsible for managing
its credit relationship with its dealers and may establish, in connection with
its acceptance of orders from dealers and delivery of orders to ACI, reasonable
credit policies including, as it deems necessary, requirements for COD sales
only.

                           2.4.3 Payments by Rockford to ACI. ACI shall submit
no later than Tuesday of each week an invoice to Rockford for all products
shipped to Rockford's dealers during the previous calendar week. The amount of
the invoice shall be for the Net Dealer Price less (1) a discount of
(Confidential material redacted and filed separately with the Commission) of the
Net Dealer Price constituting Rockford's marketing and administrative fee for
soliciting sales of the Products and collecting payments from its dealers and
(2) a discount of (Confidential material redacted and filed separately with the
Commission) of the Net Dealer Price for sales through December 31, 1996, and
(Confidential material redacted and filed separately with the Commission) of the
Net Dealer Price for sales thereafter constituting Rockford's royalty for
permitting ACI to use the Names in connection with sales of the Products.
Rockford shall pay ACI the amount of the invoice no later than Friday of the
week the invoice is submitted (except that, if the invoice is submitted later
than Tuesday, then Rockford shall pay no later than Friday

                                      -2-
<PAGE>   3
of the following week). Rockford shall have the right to net against such
invoice the amount due Rockford on account of returns.

                           2.4.4 Returns. Rockford may accept from its dealers
returns of Products on a basis consistent with Rockford's policies for returns
of its own products. Upon receipt of a returned Product, Rockford shall deliver
the Product to ACI and shall be entitled to a credit from ACI equal to the net
amount paid by Rockford to ACI for such returned Product.

         3. IDENTIFICATION OF PRODUCTS AND USE OF NAMES.

                  3.1 Development of Products. Rockford and ACI shall cooperate
to improve existing Products and develop new Products that will satisfy the
needs of Rockford's dealers and their customers. ACI shall be principally
responsible for development of such Products, with such assistance from Rockford
as it requests or as Rockford offers. Prior to the development of any new
Products the parties shall meet and agree upon (1) the anticipated role of each
party in development of the Product, (2) any change in the marketing and
administrative fees or royalty necessary for the Product, and (3) ownership of
patents, trade secrets, copyrights and other intellectual property associated
with the Product (other than the Names, which shall remain Rockford's exclusive
property).

                  3.2 Addition of Products. ACI shall not produce or sell any
Products, and shall 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 ACI
shall also agree whether the Product is to be "exclusive" pursuant to the terms
of section 4.1 of this Agreement. Except as otherwise specifically agreed by
Rockford and ACI, Installation Accessories shall be exclusive and all other
Products, including Installation Tools, Promotional Materials, and Installation
Software, shall be non-exclusive.

                  3.3 Limited License of Names. Rockford grants ACI 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 in the United States. ACI shall
use the Names only in a manner and form approved before use in writing by
Rockford. If ACI wishes to propose a new use or form of the Names, it shall
submit its proposal in writing to Rockford. Rockford shall promptly review such
proposed use and indicate its approval or disapproval in writing; any proposed
use shall be deemed approved if Rockford does not object within 15 business days
after ACI submits it to Rockford in writing together with a written request for
its approval.

                  3.4 Quality of Products. ACI shall provide Rockford with
samples of each Product for its approval prior to any sale of the Product. ACI
shall provide production samples to Rockford 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
ACI to Rockford's dealers shall be of a quality at least equal to the samples
supplied to Rockford.

                                      -3-
<PAGE>   4
                  3.5 Goodwill and Ownership of Names. All goodwill generated by
the use of the Names or promotion of the Products shall accrue to Rockford's
benefit. ACI 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 shall not take any action challenging Rockford's
ownership and rights in the Names. ACI agrees that it shall not (1) take any
action that would interfere with Rockford's use of the Names or (2) file
applications for registration of the Names anywhere in the world.

                  3.6 Infringements. If ACI learns of any other party which it
believes is infringing on Rockford's rights in the Names it shall promptly
notify Rockford and shall cooperate with Rockford in any action Rockford chooses
to take to protect its rights in the Names. Rockford shall have sole and
exclusive control of any actions relating to such infringements.

                  3.7 No Use After Termination. Upon expiration or termination
of this Agreement, ACI shall immediately cease using the Names other than for
sales permitted after termination under the termination provisions of this
Agreement.

         4. EXCLUSIVITY, NON-COMPETE, AND EXPANSION OF TERRITORY.

                  4.1 Mutual Exclusivity. In connection with those Products
identified as "exclusive" on Exhibit A and solely during the term of this
Agreement, (1) Rockford shall not sell in the United States (or license others
to sell in the United States) products that compete with such exclusive Products
and (2) neither ACI nor any affiliate of ACI shall sell in the United States (or
license others to sell in the United States) products that compete with any of
such exclusive Products.

                  4.2 Non-Compete. ACI agrees that it shall not (1) during the
term of this Agreement and for one year after its termination, either directly
or through any affiliate, offer for sale in the United States any products that
are competitive with the exclusive Products and (2) 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 is confusingly similar to the
Names, other than Products sold under this Agreement.

                  4.3 Additional Territories. The parties intend that this
Agreement be expanded to govern sales of Products to Rockford's dealers in the
remainder of the world (except Europe, where the parties existing agreement
remains in force), including in particular Canada and Mexico. Rockford's
relationships with dealers in the rest of the world generally involve economic
and business relationships that are substantially different from Rockford's
relationships with its United States dealers. Rockford and ACI acknowledge that,
because of such differing relationships, sales to non-United States dealers may
require economic terms substantially different from those established in this
Agreement for United States dealers (including changes to the suggested dealer
and retail prices, marketing and administrative fee, royalty, and terms of
payment). For each country added to this Agreement, Rockford and ACI shall
execute and attach to this Agreement an Addendum in the form of Exhibit C, which
shall set forth the changes applicable to such country. Neither party shall be
obligated to expand this Agreement to


                                      -4-
<PAGE>   5
other countries unless the parties can agree upon appropriate terms for such an
expansion and execute an Addendum for such country.

                                      -5-
<PAGE>   6
         5. WARRANTY, TITLE, AND INDEMNITY.

                  5.1 Warranty to Dealers. Rockford and ACI shall offer
Rockford's dealers and their customers warranties for the Products consistent
with the warranties offered by Rockford for its own products. Such dealers and
their customers shall be required to return Products requiring warranty service
to Rockford.

                  5.2 ACI Warranty and Service Procedures. ACI warrants that the
Products shall be free from defects in material and workmanship for the period
of the warranty offered by Rockford to its dealers and their customers. Upon
receipt of Products requiring warranty service Rockford shall deliver such
Products to ACI. ACI shall repair or exchange returned Products, and return the
Products to Rockford's dealers or their customers, at its sole expense.

                  5.3 Encumbrances, Title, and Risk of Loss. ACI warrants that
the Products, upon shipment to Rockford's dealers, shall be free from any
security interest, lien, or other encumbrance and that it shall transfer title
to the Products to Rockford's dealers free and clear of all security interests,
liens, and other encumbrances. Risk of loss from any casualty to the Products
shall be on ACI until their receipt and acceptance by Rockford's dealers.

                  5.4 Indemnification and Insurance.

                           5.4.1 Indemnity by Rockford. Rockford shall defend,
indemnify and hold harmless ACI, and its officers, directors, employees, and
agents, (a) from all fines, suits, proceedings, claims, demands, debts,
obligations, liabilities or actions of any kind by anyone (including reasonable
attorneys' fees and costs) (a "Loss") arising from or connected with the
activities or operations of Rockford or its officers, directors, employees, or
agents, (b) from all Loss rising out of claims by third parties that ACI's
authorized use of the Names infringed on the marks or other rights of such third
parties and (c) from all Loss in product liability actions brought against ACI
involving the defective manufacture or design of Rockford products. Rockford
shall maintain product liability insurance with insurers and in amounts
reasonably satisfactory to ACI. Such insurance shall name ACI as an additional
insured and shall be cancelable by the insurer only after 30 days notice to ACI.

                           5.4.2 Indemnity by ACI; Product Liability Insurance.
ACI shall defend, indemnify and hold harmless Rockford, and its officers,
directors, employees, and agents, (a) from all Loss arising from or connected
with the activities or operations of ACI or its officers, directors, affiliates,
employees, or agents and (b) from all Loss in product liability actions brought
against Rockford involving the defective manufacture or design of Products. ACI
shall maintain product liability insurance with insurers and in amounts
reasonably satisfactory to Rockford. Such insurance shall name Rockford as an
additional insured and shall be cancelable by the insurer only after 30 days
notice to Rockford.

                           5.4.3 Procedure. A party shall give notice to the
other party of any claim, as to which it intends to seek indemnity under this
Agreement, promptly after the indemnified party learns of the claim. The
indemnifying party shall be entitled to assume the defense of any claim and, if
it does so, shall thereafter not be responsible for the expenses of


                                      -6-
<PAGE>   7
independent counsel retained by the indemnified party. The indemnified party
shall cooperate in the defense of the claim and shall not settle or compromise
any claim without the indemnifying party's consent.

                  6.1 Initial and First Renewal Term. This Agreement is for an

<PAGE>   8
damages against any amounts due, and to equitable relief) and shall not act as
an election of remedies.

         7. CONFIDENTIAL INFORMATION. During and after the term of this
Agreement, ACI and Rockford will keep confidential, and will not reproduce, copy
or disclose to any other person or firm, all trade secrets, dealer and customer
lists, and other financial, engineering, marketing, proprietary, or confidential
information ("Confidential Information") supplied to or otherwise acquired by
ACI and Rockford concerning the other, the other's business or the Products. ACI
and Rockford will not, during or after the term of this Agreement, use (either
alone or with others), disclose to any person, or encourage anyone else to
disclose any Confidential Information except for the purposes and in the manner
authorized by the other party. ACI and Rockford shall take appropriate action to
assure that all persons with access to Confidential Information comply with the
obligations established in this section.

         8. RETURN OF DOCUMENTS. Upon termination of this Agreement, ACI shall
return to Rockford all records and documents of or pertaining to Rockford or the

extract of any such record or document. Upon termination of this Agreement,
Rockford shall return to ACI all records and documents of or pertaining to ACI
or the Products and shall not make, retain or give to any other person any copy

         9. INDEPENDENT CONTRACTOR RELATIONSHIP. ACI and Rockford are
independent contractors responsible for hiring their own employees, exercising
sole and absolute discretion, judgment and control over the management and
day-to-day operations of their respective businesses, and achieving the
objectives of their businesses. This Agreement does not create a relationship of
principal and agent, franchisor and franchisee, joint venture, partnership or
employment. Neither party shall be liable for any obligations incurred by the
other except as expressly provided herein. Neither party shall act or represent
itself, directly or by implication, as an agent of the other with any authority
other than as set forth expressly in this Agreement.

         10. NOTICES. Notices under this Agreement shall be in writing and

mailed notices), but shall be effective upon receipt of the facsimile
transmission.

         11. AMENDMENT AND WAIVER. This Agreement is the entire agreement of the
parties, and supersedes all prior agreements and undertakings, with respect to
its subject matter. This Agreement may be amended only by a written document

                                    EXHIBIT A
                           SALES TERMS AND CONDITIONS

1.       ORDERING OF PRODUCTS

         (a) All purchases of Products shall be effected by Buyer's issuance of
purchase orders to Seller. Such purchase orders shall state unit quantities
Products, part numbers, descriptions of Products, applicable prices and
requested delivery dates. All orders for Products and initiate shipment thereof
as close as possible to Buyer's requested delivery date(s).

         (b) All orders for standard Products may be canceled or rescheduled by
Buyer at no charge, provided Buyer notifies Seller in writing at least sixty
(60) days prior to the originally scheduled delivery date. Requests for
cancellation or rescheduling received less than sixty (60) days prior to the
originally scheduled delivery date may be accepted at a charge to be determined
in writing by Seller.

         (c) All orders for special, custom, value-added and other non-standard
Products, including Products to be assembled in Kit form and non-franchised
Products ("Non-Standard Product") shall be non-cancelable and non-returnable.

2.       PAYMENT

         (a) Payment for Products shall be net fifty-five (55) days from date of
invoice or as otherwise agreed to in writing by Seller. Seller may in its sole
discretion at any time and from time to time change the terms of Buyer's credit,
require payment in cash before shipment of any or all of the Products specified
herein, and/or require anticipated payment of any or all amounts due or to
become due under this contract. If Seller believes in good faith that Buyer's
ability to make payments is or may be impaired, Seller may cancel any order or
any remaining balance thereof, and buyer shall remain liable to pay for any
Products already shipped. Buyer agrees to submit such financial information from
time to time as may be reasonably requested by Seller for the establishment
and/or continuation of credit terms.

         (b) Checks are accepted subject to collection and the date of
collection shall be deemed the date of payment. Any check received from Buyer
may be applied to Seller against any obligation owing by Buyer to Seller under
this or any other contract, regardless of any statement appearing on or
referring to such check, without discharging Buyer's liability for any
additional amounts owing by Buyer to Seller, and the acceptance by Seller of
such check shall not constitute a waiver of Seller's right to pursue the
collection of any remaining balance.

         (c) On any invoice not paid by maturity date (net fifty-five (55)
days), Buyer shall pay interest from maturity to date of payment at the annual
percentage rate of eighteen percent (18%) (or such lower rate as may be the
maximum allowable by law), together with Seller's costs of collection (including
reasonable attorneys' fees).

         (d) Buyer agrees to pay the entire net amount of each invoice rendered
by Seller pursuant to the terms of each such invoice without offset or
deduction.

3.       DELIVERIES/TITLE

         (a) Subject to Seller's right of stoppage in transit, delivery of the
Products to a carrier shall constitute delivery to Buyer, and risk of loss shall
thereupon pass to Buyer; however, title shall remain in Seller until Buyer makes
payment in full under the contract. Products invoiced and held by Seller for any
reason shall be at Buyer's risk and expense. Delivery route shall be the
election of Seller unless specifically designated by Buyer.

         (b) Delivery of any installment of Products within thirty (30) days
after the date specified therefor shall constitute a timely delivery.
Thereafter, delivery shall be deemed timely unless prior to shipment Seller has
received written notice of cancellation. Delay in delivery of one installment
shall entitle Buyer to cancel that installment only.

4.       FREIGHT

         Unless otherwise agreed to in writing, the F.O.B. point shall be
Buyer's dock and shipment will be by UPS Ground.

5.       FORCE MAJEURE

         Neither party shall be liable for failure to fulfill its obligations
contained herein or for delays in delivery due to causes beyond its reasonable
control, including, but not limited to, acts of God, acts or omissions of the
other party, acts or omissions of civil or military authority, Government
priorities, material shortages, fire, strikes, floods, epidemics, quarantine
restrictions, riots, war, and delays in transportation. The time for performance
of any such obligation shall be extended for the time period lost by reason of
the delay.

repair of such Products, or (3) replacement of such Products; provided, however,
that such Products must be returned to Seller, along with acceptable evidence of
purchase, within twenty (20) days from date of delivery, transportation charges
prepaid. BUYER SHALL NOT IN ANY EVENT BE ENTITLED TO, AND SELLER SHALL NOT BE

CONTRACT, TORT, WARRANTY, OR OTHERWISE.

7.       PRODUCT RETURNS

         (a) Buyer is deemed to have accepted the Products unless written notice

authority which may be paid by Seller or for which Seller may be liable shall be
paid to Seller by Buyer in addition to the purchase price of the Products.

9.       CONFIDENTIALITY

         If either party hereto receives from the other party written
information which is marked "Confidential" and/or "Proprietary" the receiving
party agrees not to use such information except in the performance hereof, and
to treat such information in the same manner as it treats its own confidential
information. Confidential information that is disclosed orally or visually shall
be confirmed as confidential or proprietary in writing within ten (10) days
after such disclosure. The obligation to keep information confidential shall not
apply to any such information that has been disclosed in publicly available
sources; is in the rightful possession of the party receiving the confidential
information without an obligation of confidentiality; or is required to be
disclosed by operation of law. Except as otherwise provided herein, the
obligation not to disclose shall be for a period of one (1) year after the
termination hereof.

liability arising out of or in connection with the use or performance of
Products in life support or nuclear applications.

upon and inure to the benefit of the parties hereto and their successors and

                                       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.
<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

<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-

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

Company that, on the date hereof and on the Closing Date, (1) if you are a

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-
<PAGE>   8
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


                                      -8-
<PAGE>   9
initially issued and sold under the Debenture Purchase Agreement and this
Agreement are held by the original holders of the Debentures or their permitted
transferees.

                  5.1      Reporting Requirements. The Company will deliver, or
cause to be delivered, to you each of the following:

                  (1)      As soon as available, and in any event within 90 days
after the end of each fiscal year of the Company, audited financial statements
of the Company with the unqualified opinion of independent certified public
accountants selected by the Company, which annual financial statements shall

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.

                  4.4      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


                                      -2-
<PAGE>   9
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.

                  4.5      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.

                  4.6      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.

         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


                                      -3-
<PAGE>   10
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.

                  11.1     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.

                  11.2     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 ACCEPTABLE TO THIS COMPANY
                  THAT REGISTRATION IS NOT REQUIRED."

                  11.3     Restriction on Other Securities. Except upon certain

exercise of this Warrant will also apply to any and all shares of capital stock

the Warrant including, without limitation, shares and securities issued or
acquired as a result of any stock dividend, stock split or exchange or any
distribution of shares or securities pursuant to any corporate reorganization,
reclassification or similar event.

                  11.4     Refusal to Transfer. The Company may refuse to effect
a transfer, sale or other disposition of this Warrant or any part thereof by the
Warrantholder or its successors or assigns except as expressly permitted by this
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.

         12.      Governing Law. This Warrant is delivered and is intended to be
performed in the State of Arizona and shall be construed and enforced in
accordance with the laws of such state.

Warrant to be signed by its duly authorized officers on __________, _____.

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

         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
                           accordance with the provisions of Section 4.1 of this
                           Agreement;

                  (e)      any certificate representing the Debentures, and the
                           shares of the Common Stock issuable upon conversion
                           of the Debentures, 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; and

                  (f)      any certificate representing the Debentures, and the
                           shares of the Common Stock issuable upon conversion
                           of the Debentures, may bear any legends required by
                           applicable state securities laws.

3.3               Investment Experience. You (a) 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, (b) 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 (c) have had access to information with
                  respect to the Company necessary to permit you to make an
                  informed investment decision.

3.4               Organization. On the date of this Agreement, and on the
                  Closing Date, (a) 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, (b) 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

                  be limited by bankruptcy, insolvency, moratorium and equitable
                  principles applicable to creditors generally.

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
                           financial statements including

                           (1)      the Company's balance sheet as at the end of
                                    the fiscal year, and

                           (2)      the related statements of income, retained
                                    earnings, and cash flows of the Company for
                                    the fiscal year.

                           The financial statements will be in reasonable detail
                           and prepared in accordance with generally accepted
                           accounting principles consistently applied. The
                           financial statements will be accompanied by the
                           unqualified opinion of independent public accountants

                           Company's chief financial officer stating (i) that
                           the financial statements were prepared in accordance
                           with generally accepted accounting principles
                           consistently applied, (ii) whether such officer has
                           knowledge of the occurrence of any default under this
                           Agreement and, if so, a statement in reasonable
                           detail of the nature of the default, and (iii)
                           computations showing whether the Company is in
                           compliance with the financial covenants set forth in
                           this Agreement;

                           Commission or any national securities exchange;

                  (d)      Notice of Violations. Promptly upon knowledge
                           thereof, notice of the Company's violation of any
                           law, rule or regulation which could materially and
                           adversely affect the Company's business or financial
                           condition; and

                  (e)      Other Information. From time to time, with reasonable
                           promptness, all other materials, reports, records, or

                           reasonably request.

         5.2      Books and Records. The Company will keep accurate books,
                  records, and accounts of the Company's business and financial
                  condition.

                  will

                  (a)      comply with the requirements of applicable laws and
                           regulations whose violation would materially and
                           adversely affect the Company's business or financial

                           by any such Environmental Laws. The Company will
                           indemnify, defend, and hold you harmless from and
                           against any claims, loss, or damage resulting from

                           indebtedness hereunder.

                  discharge, when due,

                  (a)      all taxes, assessments, and governmental charges
                           levied or imposed upon it, upon its income or
                           profits, or upon any properties belonging to it. Such
                           amounts will be paid before the date when penalties
                           attach thereto,

                  (b)      all federal, state, and local taxes required to be
                           withheld by it, and

                  (c)      all lawful claims for labor, materials and supplies

                           charge upon any properties of the Company.

                  The Company is not required to pay any tax, assessment,
                  charge, or claim whose amount, applicability or validity is
                  being contested in good faith by appropriate proceedings.

                  properties used in its business in good condition, repair, and
                  working order (normal wear and tear excepted). The Company
                  will replace or repair worn, defective, or broken parts, but
                  nothing in this section prevents the Company from
                  discontinuing the operation and maintenance of any of its
                  properties if such discontinuance is in its judgment
                  desirable.

         5.6      Insurance. The Company will obtain and at all times maintain
                  insurance with insurers believed by the Company to be
                  responsible and reputable, in such amounts and against such
                  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
                  in an orderly, efficient, and regular manner.

6.       COMPANY'S NEGATIVE 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.

         6.1      Dividends and Stock Repurchases. The Company will not declare
                  or pay any dividends (other than dividends payable solely in
                  stock of the Company) on any class of its stock or make any
                  payment on account of the purchase, redemption or other
                  retirement of any shares of such stock or make any
                  distribution in respect thereof, either directly or
                  indirectly. If the Company becomes an S Corporation (with your
                  consent and after first providing such supporting
                  documentation as you may request) the Company may pay
                  dividends equal to the amount of state and federal income tax
                  which would be due for each shareholder with respect to income
                  allocated to each shareholder as a result of the Company's
                  status as an S Corporation at the highest marginal income tax
                  rate for federal and state income tax purposes (after taking
                  into account any deduction for state income taxes in
                  calculating the federal income tax liability and for the state
                  or states in which each shareholder is liable for income
                  taxes).

         6.2      Sale or Transfer of Assets; Suspension of Business Operations.
                  The Company will not sell, lease, assign, transfer, or
                  otherwise dispose of (a) the stock of any domestic Subsidiary
                  or (b) all or a substantial part of its assets to any other
                  person (other than the sale of Inventory in the ordinary
                  course of business) and will not liquidate, dissolve or
                  suspend business operations. The Company will not transfer any
                  material property without receipt of full and adequate
                  consideration. This Agreement does not restrict any sale or
                  other disposition of Company subsidiaries organized in
                  connection with the Company's operations outside the United
                  States.

         6.3      Accounting. The Company will not adopt any material change in
                  accounting principles other than as required by generally
                  accepted accounting principles. The Company will not adopt,
                  permit or consent to any change in its fiscal year.

            1999), and (d) indebtedness incurred, assumed or guaranteed by the
            Company in connection with the acquisition by it of any property or
            asset 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.

      3.2   Exclusions from Senior Debt. Senior Debt excludes, and the
            indebtedness evidenced by this Debenture is expressly senior and

5     RIGHTS UPON DEFAULT; ACCELERATION OF INDEBTEDNESS. Upon the occurrence of
      an Event of Default:

      5.1   The entire outstanding balance of the Debenture, including the
            entire balance of principal and all accrued interest, will
            accelerate and become immediately due and payable upon written
            notice to the Company by the Holder; and

      5.2   The Company may not pay dividends or make distributions to holders
            of any class of its stock, or redeem or repurchase all or any part
            of any class of its stock.

6     CONVERSION OF DEBENTURE. This Debenture is convertible, at the option of
      the Holder, into shares of the Company's Common Stock on the following
      basis:

      6.1   Conversion Price. A conversion may be made, at any time before the
            close of business on the business day before the maturity or
            redemption date, at the rate of $10.50 per share, subject 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-
<PAGE>   4
            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>   5
            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>   6
      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, registered under the

            (the "Arizona Act") or the securities laws of any other

                    ACCEPTABLE TO THIS COMPANY THAT REGISTRATION IS NOT
                    REQUIRED."

               VOID AFTER 5:00 P.M., PHOENIX TIME, ON JUNE 1, 2007


                              ROCKFORD CORPORATION

                           INCORPORATED UNDER THE LAWS
                             OF THE STATE OF ARIZONA

This certifies that, for value received, Warrantholder is entitled to
purchase from Company, at any time before 5:00 p.m., Phoenix time, on June 1,
2007, and upon payment of the Warrant Price, the Shares.  The number of
Shares and the Warrant Price per share are subject to adjustment from time to
time as set forth below.

In this Warrant, the following terms have the following meanings:

      Warrantholder:    The Vrolyk Partnership 97-A, or the registered holder
                        or assigns

      Company:          Rockford Corporation, an Arizona corporation

      Warrant Price:    $ 14.85 per share, subject to adjustment as set forth
                        in this Warrant

      Expiration:       Ten years, or June 1, 2007

1.    Reason for Delivery. This Warrant was originally delivered as part of
      the compensation paid by Company to the original Warrantholder for
      investment banking services provided by the original Warrantholder and
      in compliance with the compensation agreement between Company and the

2.    Exercise Deadline and Expiration.  Warrantholder may exercise this
      Warrant at any time after its issuance and before 5:00 p.m., Phoenix
      time, on June 1, 2007.  If not exercised, it will expire at 5:00 p.m.
      Phoenix time on June 1, 2007, and is then void.

3.    Exercise of Warrant.

      3.1   Exercise.  Warrantholder may exercise this Warrant, in whole or
            in part, by presenting (a) this Warrant, (b) a duly executed
            Exercise Form, and (c) the Warrant Price (subject to adjustment)

            exercisable to purchase the Shares at the Warrant Price (subject
            to adjustment as provided in this Warrant).  Company is not
            required to issue fractional shares of Common Stock or other
            capital stock and, in lieu of fractional shares, will 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 before the date of exercise.

3.3         Adjustment Based Upon Stock Dividends, Combination of Shares or
            Recapitalization.  Company will adjust the Warrant Price and the
            number of Shares if, after this Warrant is issued, Company

            (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)   reclassifies its Common Stock into any other special
                  capital stock of Company, or

            (e)   distributes 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).

            After an event that requires an adjustment of the Warrant Price
            or an adjustment to the number of Shares, then Warrantholder will
            be entitled to receive upon exercise of the Warrant the number of
            Shares and other securities or assets that Warrantholder would
            have owned or have been entitled to receive after the event had
            this Warrant been exercised immediately before the event.


                                      -2-
<PAGE>   3
      3.4   Adjustment Based Upon Merger or Consolidation. Company will
            adjust the Warrant Price and the number of Shares if, after this
            Warrant is issued, Company enters into

            (a)   any consolidation or merger (other than a merger in which
                  Company is the surviving entity and which does not result
                  in any reclassification of or change in the outstanding
                  Common Stock of Company), or

            (b)   any sale or conveyance to an unaffiliated person, firm, or
                  corporation of all or substantially all of Company's assets.

                  After an event that requires an adjustment of the Warrant
                  Price, Warrantholder will have the right upon exercise of
                  this Warrant to receive the kind and amount of securities
                  and property (including cash) that Warrantholder would have
                  received if the Warrant had been converted immediately
                  before the event.

      3.5   No Adjustment for Stock Issuances, Exercise of Option and Warrant
            Rights and Other Securities.  Company will not adjust the Warrant
            Price or number of Shares when Company issues Common Stock,
            securities convertible into Common Stock, options or warrants to
            purchase Common Stock, or other securities of Company for a
            purchase price established by Company, so long as the existing
            holders of Common Stock bear the dilution of such issuance in
            equal measure with Warrantholder.

4.    Corporate Status of Shares.  All Shares (or other securities if there
      is an adjustment of the Warrant Price or number of shares issuable upon
      exercise) issued upon the exercise of this Warrant will, upon issuance
      and payment of the Warrant Price, be fully paid and nonassessable.

5.    Issuance of Stock Certificate.  Upon the exercise of this Warrant,
      Company will issue to Warrantholder a certificate or certificates
      representing the Shares (or other securities if there is an adjustment
      of the Warrant Price or number of shares issuable upon exercise).

6.    Partial Exercise and Exchange.  If Warrantholder exercises this Warrant
      for part of the Shares, Company will deliver to Warrantholder a new
      Warrant for the Shares as to which the Warrant is not exercised.
      Warrantholder may exchange this Warrant at the office of Company for
      one or more new Warrants for the same aggregate number of Shares.

7.    Loss or Destruction of Warrant.  Company will deliver a new Warrant to
      Warrantholder, of like tenor and date, if Warrantholder provides
      Company with:

      (a)   evidence satisfactory to Company of the loss, theft, destruction
            or mutilation of this Warrant and


                                      -3-
<PAGE>   4
      (b)   an indemnity upon terms satisfactory to Company or, if the
            Warrant is  mutilate, the mutilated Warrant.

8.    Status of Holder of Warrant.  This Warrant does not entitle
      Warrantholder to any voting rights or other rights as a shareholder of
      Company.  No dividends are payable or accrue in respect of this
      Warrant, or the securities issuable upon its exercise, unless and until
      this Warrant is exercised.

9.    Consequence of Exercise.  Upon the exercise of this Warrant,
      Warrantholder will, to the extent permitted by law, be deemed
      immediately to be the holder of record of the Shares (or other
      securities issuable upon exercise).  This will be the case even if the
      stock transfer books of Company are then closed or the certificates
      representing the Shares or other securities are not then actually
      delivered.

10.   Reservation of Shares.  Company will reserve out of its authorized
      shares of Common Stock (and other securities if there is 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 if there is an adjustment of
      the Warrant Price or number of shares issuable upon exercise) upon the
      exercise of this Warrant.

11.   Status Under Securities Laws.

      11.1  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.  This Warrant must be held indefinitely unless it
            is 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 Company, registration is not
            required under such Acts or laws.

      11.2  Legend.  This Warrant, and any securities issued upon the
            exercise of this Warrant, will bear 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, OR PLEDGED IN THE ABSENCE OF EFFECTIVE REGISTRATION
            STATEMENTS OR AN OPINION OF COUNSEL ACCEPTABLE TO COMPANY THAT
            REGISTRATION IS NOT REQUIRED"

      11.3  Refusal to Transfer.  Company may refuse to allow a transfer of
            all or part of this Warrant, or of any Shares or other securities
            issued upon exercise of this Warrant, except as expressly
            permitted by this Warrant.

12.   Governing Law.  This Warrant is delivered and is intended to be
      performed in the State of Arizona.  It is governed by the laws of
      Arizona.

13.   Execution. In witness whereof, Company has signed and delivered this on
      June 1, 1997.

                           SERVICES & OPTION AGREEMENT


            This AGREEMENT is between W. Gary Suttle ("Suttle"), Caroline S.
Bartol for herself individually and as representative of the estate of John
G. Bartol ("Bartol"), and Rockford Corporation, an Arizona corporation
("Rockford").  Suttle, Bartol, and Rockford agree as follows:

      1     RECITALS.

            1.1 Rockford Business. Rockford is in the business of manufacturing
and distributing high quality car and home audio products under various brand
names including "Rockford-Fosgate", "Hafler", "Rockford Carbonneau", and
"Perfect Interface".

            1.2 Bartol's Ownership. Bartol, individually or as representative of
the estate of John G. Bartol owns 51.7% of the issued and outstanding shares of
Rockford common stock and, together with trusts for the benefit of members of
her family (the "Family"), owns 64.1% of the issued and outstanding shares of
Rockford common stock. Assuming conversion of all of outstanding Rockford
debentures, exercise of all outstanding Rockford stock options and warrants, and
vesting of all "stock grants" outstanding prior to the date of this Agreement,
Bartol will own 40.75%, and together with the Family 51.9%, of Rockford's fully
diluted stock issue.

            1.3 Suttle Services to Rockford. Subject to the terms of this
Agreement, Suttle has agreed to make himself available to perform certain
services to be performed by him under the Contract between Grisanti, Galef &
Goldress, Inc. ("3G") and Rockford (the "Contract"), a copy of which is attached
hereto as Exhibit A and made a part hereof.

            1.4 Stock Option. Bartol desires to grant to Suttle an option to buy
up to 185,000 shares of Rockford common stock (currently a 14.9% interest in
Rockford on a fully diluted basis) as consideration for (1) Suttle's agreement
to provide services to Rockford under the Contract and (2) Suttle's undertaking
of the obligations provided in this Agreement.

            1.5 Rockford Participation. Rockford is a party to this Agreement in
order to consent to the grant of the option, to permit it to enforce Suttle's
obligations under this Agreement, and to permit it to withhold shares purchased
by Suttle for the purpose of paying any required withholding taxes.

      2     SUTTLE SERVICES. Suttle agrees to serve as a Director, President and
CEO of Rockford, or in such other capacity as Suttle, Bartol, Rockford and 3G
may mutually determine, on a "full time" basis for a period of not less than
three years from August 1, 1992.

            2.1 Definition of "Full Time". The term "full time" shall mean that
Suttle will devote four out of five business days (averaged in each month) to
his services for Rockford, including work at Rockford's headquarters, work for
Rockford in the field, and travel time on Rockford's behalf. Suttle is a
"partner" in, and shall continue his affiliation with, 3G. Suttle will not take
on any Interim Management assignments for 3G as president or CEO of
<PAGE>   2
another company, but may perform advisory and assessment services on behalf of
3G for its clients including Heller Financial, subject to the non-competition
obligation established in this Agreement and the time limitation set forth
above. Suttle may also continue as a director of Image Carpets and advise former
clients who seek his advice, subject to the time limitation set forth above. If
it is necessary for Suttle to spend more than one consecutive day serving 3G or
other clients, Suttle shall arrange to be in communication with his Executive
Secretary at Rockford, and other appropriate Rockford representatives, in order
to carry out his responsibilities for Rockford.

            2.2 Executive Secretary. Suttle agrees during the term of this
Agreement to employ at Rockford's expense a Confidential or Executive Secretary
to assist him in the performance of his duties for Rockford and to facilitate
communications between him and other members of Rockford's management. Such
secretary may assist other members of Rockford's management, but shall be
perceived to be Suttle's "eyes & ears" in running the organization.

            2.3 Suttle Compensation and Benefits. Suttle shall not receive any
salary or other compensation from Rockford for his services, or become eligible
for any bonus or other benefit made available to Rockford employees or to
Rockford's executive cadre; but instead he shall be compensated exclusively by
3G for his services to Rockford. Suttle will not participate in any Rockford
employee benefit plans, but may take reasonable vacations (consistent with the
needs of Rockford's business) and sick leaves (when he is actually
incapacitated). Such vacation and sick leave shall not be counted in determining
whether Suttle has worked "full time" under section 2.1 above. Suttle
acknowledges that Rockford is paying compensation directly to 3G pursuant to the
Contract.

            2.4 Indemnification. Suttle shall be entitled to be exonerated,
indemnified and held harmless by Rockford from any damages, costs and expenses
resulting from his services to Rockford; however, neither Bartol nor the Family
shall have any responsibility for such indemnification and Suttle agrees to look
solely to Rockford under the Contract if he has any claim for such
indemnification.

      3     OPTION GRANT. Bartol hereby grants to Suttle the right to purchase
up to 185,000 shares of Rockford common stock at a price of $1.59 per share on
or before August 1, 1995 and $1.95 per share thereafter until August 1, 1999,
provided that either (1) Suttle shall be an "accredited investor" as that term
is defined in the regulations of the Securities and Exchange Commission ("SEC")
on the dates of exercise of such options and shall give investment
representations reasonably satisfactory to Bartol and Rockford with respect to
his purchase(s) or (2) Suttle provides other evidence reasonably satisfactory to
Rockford (such as an opinion of counsel) that a proposed exercise is exempt from
registration under, and otherwise complies with, applicable federal and state
securities laws.

            3.1 Vesting and Exercise. The number of shares with respect to
which, and the dates when the foregoing options may be exercised (subject to the
further provisions of this Agreement), shall be as follows:


                                      -2-
<PAGE>   3
<TABLE>
<CAPTION>
                  On and After                  Vested and Exercisable
                  ------------                  ----------------------
<S>                                             <C>
                  August 1, 1992                Up to 46,250 shares
                  August 1, 1993                Up to 92,500 shares
                  August 1, 1994                Up to 138,750 shares
                  August 1, 1995                Up to 185,000 shares
</TABLE>

provided that on each vesting date Suttle must be then performing his
obligations to Rockford under this Agreement and the Contract.  Vesting shall
cease, and Suttle shall be permitted to exercise the options only with
respect to shares already vested, as of any date when Suttle's obligation to
provide full time services to Rockford is terminated pursuant to Section 4 of
the Contract.

            3.2 Special Vesting and Exercise If Shares Become Publicly Traded.
If, at any time prior to April 1, 1999, Rockford common stock becomes publicly
traded (or Rockford is merged into or acquired by any publicly owned corporation
and the Rockford common stock is exchanged for securities that are publicly
traded), Suttle shall have the right to exercise all 185,000 options (to the
extent not previously exercised) on the day of such event but the options shall
expire and may not be exercised after such day.

            3.3 Expiration. All options shall expire if not exercised on or
before the earlier of (1) August 1, 1999, (2) on the day Rockford common stock
becomes publicly traded (or Rockford is merged into or acquired by any publicly
owned corporation and the Rockford common stock is exchanged for securities that
are publicly traded), (3) 150 days after Suttle's death, (4) upon any attempted
or purported assignment of Suttle's obligations or rights under this Agreement
or (5) 150 days after Bartol's death.

            3.4 Adjustment of Number of Shares. The number of shares subject to
Suttle's options shall be adjusted upwards or downwards to reflect all stock
dividends, stock splits, reverse splits, mergers, consolidations,
recapitalizations and corporate adjustments effected by Rockford between the
date of this Agreement and the date of any option exercise.

            3.5 Notice of Exercise and Payment for Shares. Suttle shall give
Bartol and Rockford written notice of his intention to exercise his options, of
the date on which he intends to exercise his options (the "Exercise Date" or
"Closing Date"), and of the number of shares to be purchased, not less than 10
nor more than 90 days before the Closing Date. The written notice shall create a
binding obligation on Suttle to purchase the specified number of shares on the
Closing Date. All shares purchased shall be delivered by Bartol and paid for in
cash by Suttle on the Closing Date.

            3.6 Taxes and Cancellation of Shares. Suttle acknowledges that, as
an independent contractor, upon exercise of the options he may become subject to
(and is solely responsible for) payment of tax on the excess of the fair market
value of the shares purchased over the option exercise price. Rockford may
become entitled to a deduction in the same amount pursuant to provisions of the
Internal Revenue Code of 1986 and Internal Revenue Service ("IRS") regulations
thereunder (the "Code") that attribute to Rockford the options granted by
Bartol. Suttle agrees that Rockford may elect to cancel (from the shares
presented by Bartol for


                                      -3-
<PAGE>   4
transfer of record to Suttle pursuant to an option exercise) up to that
percentage of shares that is equal to the maximum marginal rate of taxes Suttle
would be required by the Code to pay to the IRS upon exercise of the options;
Rockford shall then pay the fair market value of any canceled shares to the IRS
for Suttle's account. At Suttle's option Suttle may pay to Rockford the cash
value attributed to the canceled shares, at the time of the transfer of record,
in which event Rockford shall transfer to Suttle all the shares presented for
transfer. Rockford represents that it will make an election to cancel shares
only upon advice of its professional advisors that such action is necessary to
protect its deduction (and then only in the amount required by the Code); such
an election shall not constitute an admission by either Suttle or Rockford that
Suttle is an employee of Rockford and Suttle shall at all times be an
independent contractor to Rockford.

      4     ELECTION OF DIRECTORS. Bartol and Suttle agree to vote as Directors
and to cast their ballots as shareholders of Rockford (to the extent they are
now or, during the term of this Agreement, become Directors or shareholders) so
as to set the number of Directors at 5 and to elect John P. Lloyd, Nicholas
Bartol, Caroline S. Bartol Glen J. Carrio, and Suttle to serve as Directors.
This Voting Agreement shall be subject, however, to the approval in advance of
John P. Lloyd, representing Provident Mutual Life Insurance Company.

      5     OWNERSHIP OF WORKS. All ideas, artworks, compositions, conceptions,
and materials ("Works") prepared by Suttle during the term of his engagement for
Rockford, pursuant to this Agreement and the Contract, and usable in Rockford's
business shall be the property of Rockford. Suttle hereby assigns to Rockford
all of Suttle's right, copyright, title and interest in such Works. Suttle shall
not use, or transfer to others, any Works other than in connection with
Rockford's business or with Rockford's written consent; provided that Rockford
hereby grants Suttle a non-exclusive right to use the Works personally in any
activity that is not competitive with Rockford.

      6     CONFIDENTIAL INFORMATION. During and after the term of Suttle's
engagement pursuant to this Agreement and the Contract, Suttle will keep
confidential, and will not reproduce, copy or disclose to any other person or
firm, any trade secrets and other proprietary or confidential information and
data concerning Rockford or its business ("Confidential Information"). Suttle
will not, during or after the term of this Agreement, use (either alone or with
others), disclose to any person, or encourage anyone else to disclose, any
Confidential Information except within the scope of Suttle's duties and
responsibilities for Rockford or with Rockford's consent.

      7     RETURN OF ROCKFORD DOCUMENTS. Upon termination of Suttle's
engagement pursuant to this Agreement and the Contract, Suttle shall return to
Rockford all records and documents of or pertaining to Rockford (including, but
not limited to, customer, distributor, and supplier lists, names, or addresses)
and shall not make, retain or give to any other person any copy or extract of
any such record or document. "Record" includes, but is not limited to,
information stored on computer.

      8     NON-COMPETE AND SOLICITATION. During the term of Suttle's engagement
for Rockford pursuant to this Agreement and the Contract, and for 2 years
thereafter, Suttle will not engage in, plan for, organize, work for, acquire an
ownership interest in, or assist, directly or indirectly, any business that
competes with Rockford in the United States or elsewhere. During


                                      -4-
<PAGE>   5
and after the term of Suttle's engagement for Rockford pursuant to this
Agreement and the Contract, Suttle will not solicit, or assist others to
solicit, any customers, distributors, suppliers, or employees of Rockford who
did business or agreed to do business with Rockford at any time before or during
the term of Suttle's engagement for Rockford pursuant to this Agreement and the
Contract. If this section is deemed unreasonable as to time or scope by any
court or arbitrator, then such court or arbitrator shall have authority to
modify this section as to time or scope, or both, so that this section is
reasonable and shall then enforce this section as modified. Suttle acknowledges
and agrees that the market for Rockford's product is limited and international
in scope, so that any competitive activities in violation of this section would
cause material harm to Rockford and Bartol.

      9     ACTIONS. Suttle acknowledges that it would be difficult to determine
damages, and Rockford and Bartol will not have an adequate remedy at law, if
Suttle breaches this Agreement. Accordingly, if Suttle breaches this Agreement,
Rockford or Bartol may seek injunctive relief to enforce this Agreement. Nothing

                                    AMENDMENT
                                       OF
                           SERVICES & OPTION AGREEMENT

            quality car and professional audio products under various brand
            names including "Rockford-Fosgate", "Hafler Professional", "Rockford
            Acoustic Designs", and "Connecting Punch".

      1.2   Prior Agreement. Suttle, Bartols, and Rockford were parties to a
            Services and Option Agreement, and Suttle, Monument and Rockford are
            parties to the Amendment and Renewal of Services and Option
            Agreement effective as of August 1, 1995 (the "Prior Agreement")
            under which Suttle holds options to purchase up to 185,000 shares of
            Rockford common stock from Monument (the "Prior Options"). Bartols
            assigned their shares of Rockford to Monument and Monument has
            assumed Bartols' obligations under the Prior Agreement and Prior
            Options. The Prior Agreement was for the period August 1, 1992,
            through August 1, 1995.

      1.3   Monument's Ownership. Monument, an Arizona limited partnership
            formed for the benefit of members of the Bartols' family (the
            "Family"), owns a majority of the issued and outstanding shares of
            Rockford common stock. Monument together with the Family will own
            35.45% of Rockford's fully diluted stock issue assuming (a)
            conversion of all of the outstanding Rockford debentures, (b)
            exercise of all outstanding Rockford stock options and warrants
            (including the Prior Options), and (c) vesting of all "stock grants"
            outstanding prior to the date of this Agreement.

      1.4   Suttle Services to Rockford. Suttle has made himself available to
            perform certain services under the Contract between Grisanti, Galef
            & Goldress, Inc. ("3G") and Rockford (the "Contract"), a copy of
            which is attached as Exhibit A.

      1.5   Stock Option. Monument desires to amend and extend the Prior Options
            as consideration for (1) Suttle's agreement to provide services to
            Rockford under the Contract and (2) Suttle's undertaking of the
            obligations provided in this Agreement.

      1.6   Rockford Participation. Rockford is a party to this Agreement in
            order to consent to the grant of the option, to permit it to enforce
            Suttle's obligations under this Agreement, and to permit it to
            withhold shares purchased by Suttle for the purpose of paying any
            required withholding taxes.

2     SUTTLE SERVICES.

      2.1   Suttle Services. Suttle will serve as Director, President and CEO of
            Rockford (or in another capacity agreed by Suttle, Monument, and
            Rockford) on a "full time" basis pursuant to the terms of the
            Employment Agreement. In consideration of such services, the parties
            agree that (1) all references in the Prior Agreement to the Contract
            will, beginning on the date of this Amendment, be deemed to refer in
            addition to the Employment Agreement and (2) the requirements in the
            Prior Agreement that Suttle provide services to Rockford under the
            Contract will be satisfied by Suttle's providing of service to
            Rockford under the Employment Agreement.

      2.2   Definition of "Full Time". "full time" means that Suttle will devote
            four out of five business days (averaged in each month) tohis
            services for Rockford including work at Rockford's headquarters,
            work for Rockford in the field, and travel time on Rockford's
            behalf. Periods of vacation and sick leave permitted under this
            Agreement do not count in determining whether Suttle has worked
            "full time".

      2.3   Service to 3 G and its Clients. Suttle is a "partners" in, and plans
            to continue his affiliation with, 3G. Suttle will not take on any
            Interim Management assignments for 3G. Subject to the non-
            competition obligation established in this Agreement and the time
            limitation set forth above, Suttle may (a) perform advisory and
            assessment services on behalf of 3G for its clients, (b) continue as
            a director of Image Carpets, and (c) advise former clients who seek
            his advise.

      2.4   Executive Secretary. Suttle will employ (at Rockford's expense) a
            Confidential or Executive Secretary to assist him in the performance
            of his duties for Rockford.

      2.5   Suttle Compensation and Benefits. Suttle will be compensated
            exclusively by 3G for his services to Rockford and will not receive
            compensation directly from Rockford. Suttle will not participate in
            any Rockford employee benefit plans except as otherwise agreed by
            Rockford and Suttle, but may take reasonable vacations (consistent
            with the needs of Rockford" business) and sick leaves (when he is
            actually incapacitated). Suttle acknowledges that Rockford is paying
            compensation directly to 3G pursuant to the Contract.

      2.6   Indemnification. Suttle will be indemnified and held harmless by
            Rockford from any damages, costs, and expenses resulting from his
            services to Rockford. Neither Monument nor the Family will have any
            responsibility for such indemnification and Suttle will look solely
            to Rockford under the Contract if he has any claim for
            indemnification.

3     OPTION AMENDMENT. Monument amends and extends the Prior Option so that
      Suttle has the right to purchase up to 185,000 shares of Rockford common
      stock at the following prices during the following terms:

<TABLE>
<CAPTION>
            Price                            Term

<S>                                          <C>
      $1.59 per share                        on or before August 1, 1995
      $1.95 per share                        on or before August 1, 1999
      $3.00 per share                        on or before August 1, 2002
</TABLE>

This amends to Prior Option by adding the right to purchase shares during the
period after August 1, 1999, and before August 1, 2002.  The Prior Option as
amended is referred to in this Agreement as the "Option".

      3.1   Qualification to Purchase. In order to exercise the Option (a)
            Suttle must be an "accredited investor" on the dates of exercise and
            must give investment representation reasonably satisfactory to
            Monument and Rockford or (b) Suttle must provide other evidence
            reasonably satisfactory to Rockford that a proposed exercise is
            exempt from registration under, and otherwise complies with,
            applicable federal and state securities laws.

      3.2   Vesting and Exercise. The prior Option provided a vesting period
            before Suttle was permitted to exercise. The vesting period was
            completed on August 1, 1995, and Suttle may exercise the Option at
            any time before expiration.

      3.3   Expiration. The Option expires and may not be exercise after the
            earliest of the following dates:

            (a)   August 1, 2002,

            (b)   24 months after the day Rockford common stock becomes publicly
                  traded,

            (c)   24 months after the day Rockford is merged into or acquired by
                  any publicly owned corporation and Rockford common stock is
                  exchanged for securities that are publicly traded,

            (d)   150 days after Suttle's death, or

            (e)   upon any attempted or purported assignment of the Options
                  other than an assignment to a trust for the benefit of Suttle
                  or members of his family.

      3.4   Adjustment of Number of Shares. The number of shares subject to the
            Option, will be adjusted upwards or downwards to reflect all stock
            dividends, stock splits, reverse splits, mergers, consolidations,
            recapitalizations and corporate adjustments effected by Rockford
            between the date of this Agreement and the date of any option
            exercise.

      3.5   Notice of Exercise and Payment for Shares. Suttle must give Monument
            and Rockford written notice of his intention to exercise the Option
            not less than 10 nor more than 90 days before the date on which he
            intends to exercise his options (the


                                      -3-
<PAGE>   4
            "Exercise Date" or "Closing Date"). The notice must state the
            Closing Date and the number of shares to be purchased. the notice
            creates a binding obligation on Suttle to purchase the specified
            number of shares on the Closing Date. Monument must deliver the
            shares, and Suttle must pay for them in cash, on the Closing Date.

      3.6   Taxes and Cancellation of Shares. Suttle acknowledges that, as an
            independent contractor, upon exercise of the options he may become
            subject to (and is solely responsible for) payment of tax on the
            excess of the fair market value of the shares purchased over the
            option exercise price. Rockford may become entitled to a deduction
            in the same amount pursuant to provision of the Internal Revenue
            Code of 1986 and Internal Revenue Service ("IRS") regulations
            thereunder (the "Code") that attribute to Rockford the options
            granted by Monument. Rockford may elect to cancel (from the shares
            presented by Monument for transfer to Suttle pursuant to an option
            exercise) up to that percentage of shares that is equal to the
            maximum marginal rate of taxes Suttle would be required by the Code
            to pay to the IRS upon exercise of the options; Rockford will then
            pay the fair market value of any canceled shares to the IRS for
            Suttle's account. At the time of any exercise Suttle may pay the
            cash value attributed to the canceled shares to Rockford and
            Rockford will then transfer to Suttle all the shares presented for
            transfer. Rockford will make an election to cancel shares only upon
            advise of its professional advisors that such action is necessary to
            protect its deduction (and then only in the amount required by the
            Code); such an election will not constitute an admission by either
            Suttle or Rockford that Suttle is an employee of Rockford and Suttle
            will at all times be an independent contractor to Rockford.

4     ELECTION OF DIRECTORS. Monument and Suttle will vote as Directors and
      shareholders of Rockford (to the extent they are OR become Directors or
      shareholders) so as to set the number of Directors at 5 and to elect John
      P. Lloyd, Nicholas Bartol, Caroline S. Bartol, Glen J. Carrio, and Suttle
      to serve as Directors (or such other number of directors and candidates as
      they agree upon).



5     OWNERSHIP OF WORKS. All ideas, artworks, compositions, conceptions, and
      materials ('Works") prepared by Suttle during the term of his engagement
      for Rockford, pursuant to this Agreement and the Contract, and usable in
      Rockford's business will be the property of Rockford. Suttle assigns to
      Rockford all of Suttle's right, copyright, title and interest in such
      Works. Suttle will not use, or transfer to others, any Works other than in
      connection with Rockford's business or with Rockford's written consent;
      provided that Rockford grants Suttle a non-exclusive right to use the
      Works personally in any activity that is not competitive with Rockford.


                                      -4-
<PAGE>   5
6     CONFIDENTIAL INFORMATION. During and after the term of Suttle's engagement
      pursuant to this Agreement and the Contract, Suttle will keep
      confidential, and will not reproduce, copy or disclose to any other person
      or firm, any trade secrets or other proprietary or confidential
      information of Rockford or about its business ("Confidential
      Information'). Suttle will not, during or after the term of this
      Agreement, use (either alone or with others), disclose to any person, or
      encourage anyone else to disclose, any Confidential Information except
      within the scope of Suttle's duties and responsibilities for Rockford or
      with, Rockford's consent.

7     RETURN OF ROCKFORD DOCUMENTS. Upon termination of Suttle's engagement
      pursuant to this Agreement and the Contract, Suttle will return to
      Rockford all records and documents of or pertaining to Rockford
      (including, but not limited to, customer, distributor, and supplier lists,
      names, or addresses) and will not make, retain, or give to any other
      person any copy or extract of any such record or document. "Record"
      includes, but is not limited to, information stored on computer.

8     NON-COMPETE AND SOLICITATION. During the term of Suttle's engagement for
      Rockford pursuant to this Agreement and the Contract, and for 2 years
      thereafter, Suttle will not engage in, plan for, organize, work for,

      business that competes with Rockford in the United States or elsewhere.
      During and after the term of Suttle's engagement for Rockford pursuant to
      this Agreement and the Contract, Suttle will not solicit, or assist others
      to solicit, any customers, distributors, suppliers, or employees of
      Rockford who did business or agreed to do business with Rockford at any
      time before or during the term of Suttle's engagement for Rockford
      pursuant to this Agreement and the Contract.

If this section is deemed unreasonable as to time or scope by any court or
arbitrator, then such court or arbitrator is directed to modify this section
as to time or scope, or both, so that this section is reasonable and to then
enforce this section as modified.  Suttle acknowledges and agrees that the
market for Rockford's product is limited and international in scope, so that
any competitive activities in violation of this section would cause -material
harm to Rockford and Monument.



9     ACTIONS. Suttle acknowledges that it would be difficult to determine
      damages, and Rockford and Monument will not have an adequate remedy at
      law, if Suttle breaches this Agreement. Accordingly, if Suttle breaches
      this Agreement, Rockford or Monument may seek injunctive relief to enforce
      this Agreement. Nothing in this section limits or excludes any and all
      other rights, including rights to money damages, granted to Rockford or
      Monument in law or equity,

10    SEVERABILITY. If any section of this Agreement is deemed unreasonable by a
      court or arbitrator, that section is severable from the remainder of this
      Agreement, which is to be enforced according to its terms irrespective of
      the enforceability of the unreasonable section SO long AS enforcement is
      consistent with the general intent of the parties as evidenced by this
      Agreement taken as a whole.

      the personal representative of his estate. Any attempted or purported
      assignment of Suttle's obligations oR rights under this Agreement is a
      material breach and will result in the immediate termination of the
      Option.

      with a mutually acceptable third party selected by Monument (and pursuant
      to documentation approved by Monument and Suttle) a certificate for not

      option price to Monument.

                                    AMENDMENT
                                       OF
                           SERVICES & OPTION AGREEMENT

This Agreement is between W. Gary Suttle ("Suttle"), Monument Investors
Limited Partnership ("Monument") as successor to Caroline S. Bartol and the
estate of John G. Bartol ("Bartols"), and Rockford Corporation, an Arizona
corporation ("Rockford").  Suttle, Monument, and Rockford agree as follows:

1     RECITALS.

      1.1   Rockford Business. Rockford manufactures and distributes high
            quality car and professional audio products under various brand
            names including "Rockford-Fosgate", "Hafler Professional",
            "Rockford Acoustic Designs", and "Connecting Punch".

      1.2   Prior Agreement. Suttle, Bartols, and Rockford were parties to a
            Services and Option Agreement, and Suttle, Monument and Rockford are
            parties to the Amendment and Renewal of Services and Option
            Agreement effective as of August 1, 1995 (the "Prior Agreement")
            under which Suttle holds options to purchase up to 185, 000 shares
            of Rockford common stock from Monument (the "Prior Options").

      1.3   Suttle Services to Rockford. Suttle has made himself available to
            perform certain services under the contract between Grisanti, Galef
            & Goldress, Inc. ("3G") and Rockford (the "Contract"), a copy of
            which is attached as Exhibit A. Suttle and Rockford have now agreed
            to end Suttles provision of services under the Contract. Instead,
            Rockford will employ Suttle directly under a new Employment
            Agreement between Suttle and Rockford (the "Employment Agreement").

      1.4   Stock Option. Monument desires to amend the Prior Options as
            consideration for (1) Suttle's entry into the Employment Agreement
            and (2)Suttle's undertaking of the obligation provided in this
            Agreement.

2     SUTTLE SERVICES. Suttle will serve as Director, President and CEO of
      Rockford (or in another capacity agreed by Suttle, Monument, and Rockford)
      on a "full time" basis pursuant to the terms of the Employment Agreement.
      In consideration of such services, the parties agree that (1) all
      references in the Prior Agreement to the Contract will beginning on the
      date of this Amendment be deemed to refer in addition to the Employment
      Agreement and (2) the requirements in the Prior Agreement that Suttle
      provide service sot Rockford under the Contract will be satisfied by
      Suttle's providing of service to Rockford under the Employment Agreement.

3     EXTENSION OF OPTION. Suttle's option is extended to expire on December 31,
      2003 (co-terminus with the scheduled expiration of the initial term of the
      Employment Agreement) by replacing the words "August 31, 2002" in the text
      of Section 3 and in Section 3.3(a)


                                      -8-
<PAGE>   2
      with the words "December 31, 2003." The exercise price of the options
      during the extended option period is established at $3.50 per share by
      amending the table in Section 3 to read as follows:

<TABLE>
<CAPTION>
                  Price             Term
                  -----             ----
<S>                                 <C>
            $1.59 per share         on or before August 1, 1995
            $1.95 per share         on or before August 1, 1999
            $3.00 per share         on or before August 1, 2002
            $3.50 per share         on or before August 1, 2003
</TABLE>


4     AMENDMENT. Sections 2 and 4 are deleted from the Prior Agreement and have
      no further effect. All other sections of the Prior Agreement, including
      Section 3 granting to Suttle the Prior Option, continue in effect without
      change other than the change set forth above.

5     EXECUTION AND EFFECTIVE DATE. This Amendment is effective as of January 1,
      1999.

                        CONSULTING AND OPTION CONTRACT


            This CONTRACT is between Rockford Corporation, an Arizona
corporation ("Rockford") and Grisanti, Galef & Goldress, Inc., a  Nevada
corporation ("3G").  Rockford and 3G agree as follows:

      1     RECITALS.

            1.1 Rockford Business. Rockford is in the business of manufacturing
and distributing high quality car and home audio products under various brand
names including "Rockford-Fosgate", "Hafler", "Rockford Carbonneau", and
"Perfect Interface".

            1.2 3G Consulting Services. 3G is in the business of providing
executive and other consulting services. 3G has provided certain services to
Rockford pursuant to a letter agreement dated February 8, 1992, and accepted by
3G on February 10, 1992 (the "Letter Agreement"). 3G has now agreed to provide
longer term executive and consulting services to Rockford through the person of
W. Gary Suttle ("Suttle"), one of 3G's associates.

            1.3 Related Agreement. This Contract is interrelated to a
substantially contemporaneous Agreement (the "Agreement"), between Suttle and
Caroline S. Bartol for herself individually and for the estate of John G. Bartol
("Bartol") the principal stockholder of Rockford, (1) providing for a side
option on 185,000 shares of Rockford stock to be granted by Bartol to Suttle,
(2) requiring that Suttle devote "full time" (as defined therein) to his
services to Rockford, and (3) establishing certain non-compete and other
obligations. A copy of the Agreement is attached hereto as Exhibit 1 and made a
part hereof.

      2     CONSULTING SERVICES AGREEMENT. For a term of not less than 3 years
from August 1, 1992, 3G shall provide executive and advisory services in the
turnaround and corporate redevelopment program of Rockford through the person of
its associate Suttle working on a "full time" basis (as defined in the
Agreement) and such other of its associate(s) as it may assign to the Rockford
engagement with Rockford's advance approval.

            2.1 Nature of Required Services. Rockford, 3G and Suttle shall from
time to time agree on the exact nature of the consulting services to be
performed hereunder.

            2.2 Suttle's Position. Suttle shall serve on a "full time" basis as
a Director, President and CEO of Rockford, or in such other capacity as
Rockford, Bartol, Suttle and 3G may from time to time mutually determine, and he
shall carry out the duties of such offices on an independent contractor basis
and not as Rockford's employee or servant.

            2.3 Advisory Director. 3G shall designate its associate Jerry
Goldress to serve as an "Advisory Director" of Rockford during the term hereof
with the right to receive notice of, to attend, and to speak at meetings of
Rockford's Directors, but not to vote on any actions to be taken.

            2.4 Compensation of 3G Associates. 3G shall pay, and bear
exclusively, all compensation of Suttle, Goldress, and any other 3G associate
working on the Rockford engagement.

      3     ROCKFORD COOPERATION. In order to facilitate the performance of 3G's
consulting services under this Contract, Rockford agrees to extend full
cooperation to 3G and Suttle, to provide full access to all of its employees,
officers, consultants and Directors and to provide full access to all of its
<PAGE>   2
files, books and corporate and financial records. Rockford also agrees to
consult and cooperate with Suttle in the formulation and adoption of its
financial and operating policies and practices. Suttle and 3G shall review and
approve all of Rockford's policies and practices proposed to be adopted and
shall participate in all major decisions which may have a significant impact on
their engagement; however, notwithstanding the foregoing, control of Rockford
and its business shall at all times be and remain in the control of Rockford's
Board of Directors.

      4     TERMINATION. This Contract may be terminated at any time by either
of Rockford or 3G by 90 days notice in writing given to the other party.
Effective upon such termination Suttle shall withdraw and be released from his
obligation to Rockford set forth in Section 2 of the Agreement.

      5     COMPENSATION AND EXPENSES.

            5.1 Base Retainer. Rockford agrees to pay to 3G as part of its
compensation under this Contract a retainer fee of $30,000 per month payable in
advance on the 8th day of each month. This retainer fee shall be non-refundable
except in the event that this Contract shall be terminated by 3G pursuant to the
provisions of Section 4 hereof effective on some day other than the 8th day of
the month, in which case the final fee payment shall be pro-rated or a refund
given for any unearned portion.

            5.2 Bonus Fees. As additional compensation for 3G's services under
this Contract, Rockford shall pay to 3G up to $120,000 per year of bonus fees,
from and after October 1, 1992, until the termination of this Contract. Payments
of bonus fees shall be made on the 8th day of the month during the months of
February, April, July and October and shall be paid for the preceding calendar
quarter (for example, the first payment, if earned, will be due February 8,
1993, and will be for the quarter from October 1, 1992, through December 31,
1992). Bonus fees shall be paid at the rate of up to $30,000 per quarter, but
shall cumulate during the fiscal year up to a maximum of $120,000 per year.
Bonus fees shall be earned at the rate of 3.2% of the quarterly increase in
Earnings Before Interest & Taxes (but after any accrual for employee incentive
bonuses) ("EBIT") over Rockford's quarterly EBIT results for its 1992 fiscal
year. Attached hereto as Exhibit 2 is an example of the calculation of the
target bonus fee payments for Fiscal 1993, which should be repeated in 1994 and
thereafter during the term of this Contract.

            5.3 Termination Fees. If this Contract is terminated by Rockford,
Rockford shall continue to pay to 3G its base retainer and bonus fees for a
period of 6 months commencing from the date of termination, provided that such
termination payments period shall not extend beyond the third anniversary of
this Contract.

            5.4 Option Compensation. As contingent compensation for 3G's
services hereunder, Rockford hereby grants to 3G options on or before August 1,
1999 to purchase 50,000 of its authorized but unissued common stock at a price
of $23.00 per share, protected against dilution only from stock dividends, stock
splits, reverse stock splits, mergers, consolidations, recapitalizations and
corporate adjustments.

                  5.4.1 Contingency for Exercise and Expiration. 3G's right to
exercise these options shall be contingent upon Rockford's stock becoming
publicly traded, or Rockford being merged into or acquired by a private or
publicly owned concern (a "Successful Result"). If a Successful Result does not
transpire, or if 3G's options are not exercised, by August 1, 1999, the options
shall expire on that date. If the options become exercisable by reason of a
Successful Result they shall be exercisable only within 90 days after such event
and shall then expire.


                                      -2-
<PAGE>   3
                  5.4.2 Vesting. 3G's options shall vest 25% on August 1, 1992
and 25% on each of August 1, 1993, 1994 and 1995, provided that 3G and Suttle
shall on each such vesting date still be performing the services required of
them under this Contract and the Agreement and that no notice of termination
shall have been given by 3G to Rockford prior to such vesting date. They shall
also vest 100% upon an earlier Successful Result.

                  5.4.3 Limited Assignment Right. 3G shall have the right to
assign its options granted hereunder to and among its associates (including
Suttle) or to any corporation, firm or joint venture formed by them to hold the
options, but no other assignment shall be permissible.

                  5.4.4 Investment Representation. The right of 3G or any
permitted assignee to exercise the options (or his or her share thereof) shall
be conditioned upon (1) qualification as an "accredited investor" as that term
is defined in the regulations of the SEC on the date of exercise of the options
and the making of adequate investment representations with respect to such
purchases or (2) other evidence reasonably satisfactory to Rockford (such as an
opinion of counsel) that the proposed exercise is exempt from registration
under, and otherwise complies with, applicable federal and state securities
laws.

                  5.4.5 Notice of Exercise and Payment upon Exercise. 3G or its
permitted assignee shall give Rockford written notice of its intention to
exercise the options, of the date on which it intends to exercise the options
(the "Closing Date" or "Exercise Date"), and of the number of shares to be
purchased, not less than 10 nor more than 90 days before the Closing Date. The
written notice shall create a binding obligation on 3G or its permitted assignee
to purchase the specified number of shares on the Closing Date. All shares
purchased shall be delivered by Rockford and paid for in cash by 3G or its
permitted assignee on the Closing Date.

                  5.4.6 Taxes and Election not to Issue Shares. 3G acknowledges
that, as an independent contractor, upon exercise of the options it (or its
permitted assignee) may become subject to (and is solely responsible for)
payment of tax on the excess of the fair market value of the shares purchased
over the option exercise price. Rockford may become entitled to a deduction in
the same amount pursuant to provisions of the Internal Revenue Code of 1986 and
IRS regulations thereunder (the "Code"). 3G (for itself and its permitted
assignees) agrees that Rockford may elect not to issue up to that percentage of
shares that is equal to the maximum marginal rate of taxes 3G (or its permitted
assignee) would be required by the Code to pay to the IRS upon exercise of the
options; Rockford shall pay the fair market value of any withheld shares to the
IRS for the account of 3G or its permitted assignee, as applicable. At the
option of 3G or its permitted assignee, 3G or its permitted assignee may pay to
Rockford the cash amount of the shares Rockford may elect not to issue, at the
time of the exercise of the options, in which event Rockford shall issue all the
shares for which options are exercised. Rockford represents that it will make an
election not to issue shares only upon advice of its professional advisors that
such action is necessary to protect its deduction (and then it will not issue
only the amount required by the Code); such an election shall not constitute an
admission by either 3G or Rockford that 3G is an employee of Rockford and 3G
shall at all times be an independent contractor to Rockford.

            5.5 Expense Reimbursement. In addition to compensation provided
hereunder, Rockford shall reimburse 3G for its reasonable out of pocket expenses
incurred on Rockford's behalf, subject to Rockford's (1) advance approval of
expenses in excess of $2,500 in any month or $1,000 for any single item and (2)
right to require adequate documentation of expenses.

      6     CONFIDENTIAL INFORMATION. During and after the term of 3G's
engagement pursuant to this Contract, 3G and its associates will keep
confidential, and will not reproduce, copy or disclose to any other person or
firm, any trade secrets and other proprietary or confidential information and
data concerning Rockford or its business ("Confidential Information"). 3G and
its associates will not, during


                                      -3-
<PAGE>   4
or after the term of this Agreement, use (either alone or with others), disclose
to any person, or encourage anyone else to disclose, any Confidential
Information except within the scope of 3G's duties and responsibilities for
Rockford or with Rockford's consent.

      7     RETURN OF ROCKFORD DOCUMENTS. Upon termination of 3G's engagement
pursuant to this Contract, 3G shall return to Rockford all records and documents
of or pertaining to Rockford (including, but not limited to, customer,
distributor, and supplier lists, names, or addresses) and shall not make, retain
or give to any other person any copy or extract of any such record or document.
"Record" includes, but is not limited to, information stored on computer.

      8     NON-SOLICITATION. During and after the term of 3G's engagement for
Rockford pursuant to this Agreement and the Contract, 3G will not solicit, or
assist others to solicit, any customers, distributors, suppliers, or employees
of Rockford who did business or agreed to do business with Rockford at any time
before or during the term of 3G's engagement for Rockford pursuant to this
Contract. If this section is deemed unreasonable as to time or scope by any
court or arbitrator, then such court or arbitrator shall have authority to
modify this section as to time or scope, or both, so that this section is
reasonable and shall then enforce this section as modified. 3G acknowledges and
agrees that the market for Rockford's product is limited and international in
scope, so that any solicitation activities in violation of this section would
cause material harm to Rockford.

      9     ACTIONS. 3G acknowledges that it would be difficult to determine
damages, and Rockford will not have an adequate remedy at law, if 3G breaches
this Contract. Accordingly, if 3G breaches this Contract, Rockford may seek
injunctive relief to enforce this Contract. Nothing in this section shall limit
or exclude any and all other rights, including rights to money damages, granted
to Rockford in law or equity.

      10    SEVERABILITY. If any section of this Contract is deemed unreasonable
by a court or arbitrator, such section shall be severable from the remainder of
this Contract, which shall be enforced according to its terms irrespective of
the enforceability of the unreasonable section provided such enforcement is
consistent with the general intent of the parties as evidenced by this Contract
taken as a whole.

      11    RELEASE AND INDEMNIFICATION. Rockford agrees to release, remise and
forever acquit 3G and each and all of its employees, representatives and
associates, including Suttle, working on the Rockford engagement from any and
all legal or equitable liability to it, whether undertaken hereunder or pursuant
to the Letter Agreement, so long as such liability arises out of any action, or
failure to take action, on Rockford's behalf which 3G or any of its employees,
representatives, and associates believed in good faith to be in Rockford's best
interest and not in contravention of this Contract or the Agreement. In
addition, Rockford agrees to exonerate, indemnify and hold harmless 3G, its
employees, representatives and associates, including Suttle (an "Indemnified
Party"), from and against any and all losses, damages, costs and expenses,
including all legal fees, court costs, and out-of-pocket expenses (a "Loss") in
any way arising out of or in connection with an Indemnified Party's activities
on Rockford's behalf and asserted against an Indemnified Party by Rockford, any
of its officers, Directors, debenture owners or stockholders, or any other
person, so long as such Loss arises out of any action, or failure to take
action, on Rockford's behalf which the Indemnified Party in good faith believed
to be in Rockford's best interest. In the event of a claim of Loss the
Indemnified Party shall notify Rockford promptly of the claim and Rockford shall
advance expenses incurred in connection with the claim on behalf of the
Indemnified Party. Rockford may decline to advance expenses if its Board of
Directors determines, in good faith and within 30 days after receiving notice of
the claim from the Indemnified Party, that the Indemnified Party is not entitled
to indemnification under the circumstances; however, such determination shall
not be binding upon the Indemnified Party in any action for indemnification
hereunder. Rockford shall be


                                      -4-
<PAGE>   5
entitled to assume the defense of any claim, using counsel of its choice
reasonably satisfactory to the Indemnified Party, and shall thereafter not be
responsible for the fees of counsel to the Indemnified Party.

      12    NON-ASSIGNABILITY. The rights and obligations of Rockford and 3G
under this Contract shall not be assignable except 3G's option rights to the
extent expressly permitted. Any other purported or attempted assignment of 3G's
or Rockford's rights hereunder shall constitute a material breach of this
Contract.

      13    EMPLOYMENT OF 3G PERSONNEL BY ROCKFORD . In the event that Rockford
shall employ Suttle or any other person working for 3G at any time during the
pendency of this Contract it shall become obligated to pay to 3G a sum equal to

                                       OF
                         CONSULTING AND OPTION CONTRACT


This Contract is between Rockford Corporation, an Arizona corporation
("Rockford") and Grisanti, Galef & Goldress, Inc., a Nevada corporation ("3G").
Rockford and 3G agree as follows:

1     RECITALS.

      1.1   Rockford Business. Rockford manufactures and distributes high
            quality car and professional audio products under various brand
            names including "Rockford-Fosgate", "Hafler Professional", "Rockford
            Acoustic Designs", and "Connecting Punch."

      1.2   3G Consulting Services. 3G is in the business of providing executive
            and other consulting services. 3G has provided services to Rockford
            pursuant to (a) a letter agreement dated February 8, 1992, and
            accepted by 3G on February 10, 1992, and (b) a Consulting and Option
            Contract dated March 10, 1993 (the "Prior Contracts"). Pursuant to
            the Prior Contracts, 3G has provided executive and consulting
            services to Rockford through W. Gary Suttle ("Suttle"), one of 3G's
            associates.

      1.3   Related Agreement. This Contract is related to a contemporaneous
            Agreement (the "Agreement"), between Suttle, Rockford, and Monument
            Investors Limited Partnership ("Monument") the principal stockholder
            of Rockford. The Agreement (a) grants to Suttle an Option to
            purchase 185,000 shares of Rockford common stock held by Monument,
            (b) requires that Suttle devote "full time" to his services for
            Rockford, and (c) establishes certain non-compete and other
            obligations. A copy of the Agreement is attached as Exhibit 1 and
            made a part of this Contract.

2     CONSULTING SERVICES AGREEMENT. For a term of not less than 5 years from
      August 1, 1995, 3G will provide executive and advisory services to
      Rockford through Suttle and through its other associates (with Rockford's
      advance approval). Suttle will work for Rockford on a "full time" basis as
      defined in the Agreement.

      2.1   Nature of Required Services. Rockford, 3G, and Suttle will from time
            to time agree on the exact nature of the consulting services to be
            performed under this Contract.

      2.2   Suttle's Position. Suttle will serve as Director, President, and CEO
            of Rockford (or in another capacity agreed by Rockford, Monument,
            Suttle, and 3G). Suttle will carry out the duties of such offices on
            an independent contractor basis and not as Rockford's employee.
<PAGE>   2
      2.3   Advisory Director. 3G will designate its associate Jerry Goldress to
            serve as an "Advisory Director" of Rockford, with the right to
            receive notice of, to attend, and to speak at meetings of Rockford's
            Directors, but not to vote on any matters.

      2.4   Compensation of 3G Associates. 3G will pay, and bear exclusively,
            all compensation of Suttle, Goldress, and any other 3G associate
            working on the Rockford engagement.

3     ROCKFORD COOPERATION. Rockford will extend full cooperation to 3G and
      Suttle, will provide full access to its employees, officers, consultants
      and Directors, and will provide full access to all of its files, books and
      corporate and financial records. Rockford's Board of Directors will at all
      times retain control of Rockford and its business.

4     TERMINATION. This Contract may be terminated at any time by Rockford or
      3G. Termination requires 90 days written notice. Upon termination Suttle
      will withdraw and be released from his obligations to Rockford set forth
      in Section 2 of the Agreement.

5     COMPENSATION AND EXPENSES.

      5.1   Base Retainer. Rockford will pay 3G a retainer fee of $30,000 per
            month payable in advance on the 8th day of each month. This retainer
            fee is non-refundable, except that if this Contract is terminated by
            3G effective on some day other than the 8th day of the month the
            final fee payment will be pro-rated or a refund will be given for
            any unearned portion.

      5.2   Bonus Fees. As additional compensation for 3G's services under this
            Contract, Rockford will pay 3G an annual bonus, with the amount and
            timing of payment determined by Rockford's Board of Directors taking
            into account (a) Suttle's compensation in prior positions and
            Rockford's original plan to pay bonuses sufficient to increase the
            base compensation by $120,000 per year, (b) the need to provide
            substantial "upside" compensation to Suttle if Rockford is
            successful, and (c) the bonus paid by Rockford to the most senior
            members of its management team. The initial bonus under this
            Contract will be paid for Rockford's fiscal year ended September
            1995 and will be in an amount consistent with the bonus declared for
            the most senior members of Rockford's management other than Suttle.
            3G waives and relinquishes all right to payments under the bonus
            formula established in the Prior Contracts.

      5.3   Termination Fees. If this Contract is terminated by Rockford,
            Rockford will continue to pay to 3G its base retainer for 9 months
            after the date of termination.

      5.4   Option Compensation.

            5.4.1 Prior Option. As contingent compensation for 3G's services
                  under the Prior Contracts, Rockford granted to 3G an option
                  (the "Prior Option") on or before August 1, 1999, to purchase
                  50,000 of its authorized but unissued common stock at a price
                  of $23.00 per share (the "Exercise Price"), protected against
                  dilution only from stock dividends, stock splits,


                                       -2-
<PAGE>   3
                  reverse stock splits, mergers, consolidations,
                  recapitalizations and corporate adjustments.

            5.4.2 Amendment of Prior Option. As of October 28, 1994, Rockford
                  restructured its 10.5% Convertible Subordinated Debentures
                  into Senior Notes with Warrants and reduced the exercise price
                  of the Warrants from $23.00 to $6.50. In connection with such
                  restructuring, Rockford and 3G agreed to reduce the Exercise
                  Price to $6.50 per share; this Contract constitutes written
                  acknowledgment of Rockford and 3G that the Exercise Price was
                  reduced to $6.50 per share effective as of October 28, 1994.
                  Rockford further agrees to extend the Prior Option in
                  connection with the execution of this Contract, so that 3G may
                  exercise the Prior Option at any time before August 1, 2002
                  (unless the Prior Option expires earlier under a provision of
                  this Contract). As amended and extended, the Prior Option is
                  referred to in this Contract as the "Option."

            5.4.3 [Intentionally Omitted].

            5.4.4 Vesting. The Prior Contracts provided for vesting of the Prior
                  Option over a period ending August 1, 1995. The Option is now
                  100% vested.

            5.4.5 Limited Assignment Right. 3G may assign the Options to and
                  among its associates (including Suttle) or to any corporation,
                  firm or joint venture formed by them to hold the Option. No
                  other assignment is permitted.

            5.4.6 Investment Representation. In order to exercise the Option 3G
                  or any permitted assignee (1) must qualify as an "accredited
                  investor" and must give reasonably satisfactory investment
                  representations or (2) must provide other evidence reasonably
                  satisfactory to Rockford that the proposed exercise is exempt
                  from registration under, and otherwise complies with,
                  applicable federal and state securities laws.

            5.4.7 Notice of Exercise and Payment upon Exercise. 3G or its
                  permitted assignee must give Rockford written notice of its
                  intention to exercise the Option not less than 10 nor more
                  than 90 days before the date on which it intends to exercise
                  the Option (the "Closing Date" or "Exercise Date"). The notice
                  must state the Closing Date and the number of shares to be
                  purchased. The notice creates a binding obligation on 3G or
                  its permitted assignee to purchase the specified number of
                  shares on the Closing Date. Rockford must deliver the shares,
                  and 3G or its permitted assignee must pay for them in cash, on
                  the Closing Date.

            5.4.8 Taxes and Election not to Issue Shares. 3G acknowledges that,
                  as an independent contractor, upon exercise of the options it
                  (or its permitted assignee) may become subject to (and is
                  solely responsible for payment of) tax on the excess of the
                  fair market value of the shares purchased over the option
                  exercise price. Rockford may become entitled to a deduction in


                                       -3-
<PAGE>   4
                  the same amount pursuant to provisions of the Internal Revenue
                  Code of 1986 and IRS regulations thereunder (the "Code").
                  Rockford may elect not to issue up to that percentage of
                  shares that is equal to the maximum marginal rate of taxes 3G
                  (or its permitted assignee) would be required by the Code to
                  pay to the IRS upon exercise of the options; Rockford will pay
                  the fair market value of any withheld shares to the IRS for
                  the account of 3G or its permitted assignee, as applicable. At
                  the time of any exercise 3G or its permitted assignee may pay
                  the cash value attributed to the withheld shares to Rockford
                  and Rockford will then issue all the shares for which the
                  Option is exercised. Rockford will make an election to
                  withhold shares only upon advice of its professional advisors
                  that such action is necessary to protect its deduction (and
                  then it will withhold only the amount required by the Code);
                  such an election will not constitute an admission by either 3G
                  or Rockford that 3G is an employee of Rockford and 3G will at
                  all times be an independent contractor to Rockford.

      5.5   Split Dollar Life Insurance. Upon 3G's request, Rockford will
            institute a program of "split dollar" life insurance covering Suttle
            providing for payments by Rockford of up to $36,000 per year.

      5.6   Expense Reimbursement. In addition to compensation provided
            hereunder, Rockford will reimburse 3G or Suttle for reasonable out
            of pocket expenses incurred on Rockford's behalf, subject to
            Rockford's right to require adequate documentation of expenses.

6     CONFIDENTIAL INFORMATION. During and after the term of 3G's engagement
      pursuant to this Contract, 3G and its associates will keep confidential,
      and will not reproduce, copy or disclose to any other person or firm, any
      trade secrets or other proprietary or confidential information and data of
      Rockford or about its business ("Confidential Information"). 3G and its
      associates will not, during or after the term of this Agreement, use
      (either alone or with others), disclose to any person, or encourage anyone
      else to disclose, any Confidential Information except within the scope of
      3G's duties and responsibilities for Rockford or with Rockford's consent.

7     RETURN OF ROCKFORD DOCUMENTS. Upon termination of 3G's engagement pursuant
      to this Contract, 3G will return to Rockford all records and documents of
      or pertaining to Rockford (including, but not limited to, customer,
      distributor, and supplier lists, names, or addresses) and will not make,
      retain, or give to any other person any copy or extract of any such record
      or document. "Record" includes, but is not limited to, information stored
      on computer.

8     NON-SOLICITATION. During and after the term of 3G's engagement for
      Rockford pursuant to this Contract, 3G will not solicit, or assist others
      to solicit, any customers, distributors, suppliers, or employees of
      Rockford who did business or agreed to do business with Rockford at any
      time before or during the term of 3G's engagement for Rockford pursuant to
      this Contract.


                                       -4-
<PAGE>   5
      If this section is deemed unreasonable as to time or scope by any court or
      arbitrator, then such court or arbitrator is directed to modify this
      section as to time or scope, or both, so that this section is reasonable
      and to then enforce this section as modified. 3G acknowledges and agrees
      that the market for Rockford's product is limited and international in
      scope, so that any solicitation activities in violation of this section
      would cause material harm to Rockford.

9     ACTIONS. 3G acknowledges that it would be difficult to determine damages,
      and Rockford will not have an adequate remedy at law, if 3G breaches this
      Contract. Accordingly, if 3G breaches this Contract, Rockford may seek
      injunctive relief to enforce this Contract. Nothing in this section limits
      or excludes any and all other rights, including rights to money damages,
      granted to Rockford in law or equity.

10    SEVERABILITY. If any section of this Contract is deemed unreasonable by a
      court or arbitrator, that section is severable from the remainder of this
      Contract, which is to be enforced according to its terms irrespective of
      the enforceability of the unreasonable section so long as enforcement is
      consistent with the general intent of the parties as evidenced by this
      Contract taken as a whole.

11    RELEASE AND INDEMNIFICATION.

      11.1  Release. Rockford releases 3G (and its employees, representatives,
            and associates working on the Rockford engagement, including Suttle)
            from any and all liability to Rockford so long as such liability
            arises out of an action, or failure to take action, which 3G (or its
            employees, representatives, and associates) believed in good faith
            to be in Rockford's best interest and not in contravention of this
            Contract or the Agreement.

      11.2  Indemnity. Rockford indemnifies and holds harmless 3G, its
            employees, representatives and associates, including Suttle (an
            "Indemnified Party"), from and against any and all losses, damages,
            costs and expenses, including all legal fees, court costs, and
            out-of-pocket expenses (a "Loss") in any way arising out of or in
            connection with an Indemnified Party's activities on Rockford's
            behalf and asserted against an Indemnified Party by Rockford, any of
            its officers, Directors, debenture owners or stockholders, or any
            other person, so long as the Loss arises out of an action, or
            failure to take action, which the Indemnified Party in good faith
            believed to be in Rockford's best interest.

      11.3  Procedure, Expenses, and Defense. If there is a Loss, an Indemnified
            Party must notify Rockford promptly of the claim and Rockford will
            advance expenses incurred in connection with the claim on behalf of
            the Indemnified Party. Rockford may decline to advance expenses if
            its Board of Directors determines, in good faith and within 30 days
            after receiving notice of the claim from the Indemnified Party, that
            the Indemnified Party is not entitled to indemnification under the
            circumstances; however, such determination is not binding upon the
            Indemnified Party in any action for indemnification. Rockford is
            entitled to assume the defense of any claim, using counsel of its
            choice reasonably


                                       -5-
<PAGE>   6
            satisfactory to the Indemnified Party, and will not be responsible
            for the fees of counsel to the Indemnified Party after it assumes
            the defense.

12    NON-ASSIGNABILITY. The rights and obligations of Rockford and 3G under
      this Contract are not assignable, except 3G's may assign its option rights
      to the extent expressly permitted. Any other purported or attempted
      assignment of 3G's or Rockford's rights is a material breach of this
      Contract.

13    EMPLOYMENT OF 3G PERSONNEL BY ROCKFORD . If Rockford employs Suttle (or
      any other person working for 3G) during the term of this Contract,
      Rockford will pay 3G 35% of such person's salary and incentive bonus
      during the first year of such person's employment.

14    CONFLICTS WITH AGREEMENT. If there is a conflict between this Contract and
      the Agreement, this Contract will regulate the relations between Rockford
      and 3G and the Agreement will regulate the relations between Suttle and
      Monument.

15    NOTICES. Notices under this Contract are effective upon delivery or three
      days after mailing, certified or registered mail, return receipt
      requested, to the addresses stated on the signature page of this Contract
      (which may be changed by notice).

16    INTEGRATION AND AMENDMENT. This Contract is the entire agreement of the
      parties with respect to the engagement of 3G by Rockford, supersedes all
      prior agreements between 3G and Rockford (including the Prior Contracts),
      and may be amended only by a written document signed by both parties.

17    GOVERNING LAW. Arizona law will govern this Contract and any disputes
      arising out of or related in any way to this Contract.

18    ATTORNEYS' FEES. In any proceeding arising out of or related to this
      Contract, the prevailing party is entitled to reasonable attorneys' fees,
      costs and other expenses incurred in connection with such proceeding.

19    ARBITRATION. Disputes not resolved by the parties and arising out of or
      related in any way to this Contract will be submitted to binding
      arbitration in metropolitan Phoenix, Arizona, before a single arbitrator
      or, if the parties cannot agree upon a single arbitrator, before a panel
      of three arbitrators, one selected by each party (within 10 days after
      notice of a dispute and failure to agree upon a single arbitrator) and a
      third appointed by the arbitrators selected by the parties. The selection
      of arbitrators and all arbitration proceedings will be in accordance with
      the rules of the American Arbitration Association, as amended to the date
      of the proceedings, and judgment upon the award may be entered in any
      court having jurisdiction. The arbitrators will render a decision within

                    FIFTH AMENDMENT TO BRIDGE LOAN CONVERSION
                             AND EXTENSION AGREEMENT


            This Amendment is between Rockford Corporation, an Arizona
corporation ("Borrower") and Boulder Investors Ltd. Partnership, as successor
to Carolyn S. Bartol ("Lender").  Borrower and Lender agree as follows:

      1.    Recitals.

            1.1 Existing Agreement. Borrower and Lender are party to a Bridge
Loan Conversion and Extension Agreement (the "Loan Agreement") dated as of July
1, 1996, pursuant to which Borrower owes $1,000,001 of principal to Lender. The
original due date of December 31, 1996,

            (a)   was extended to March 30, 1997, pursuant to the First
                  Amendment to Bridge Loan Conversion and Extension Agreement
                  dated as of December 31, 1996 (the "First Amendment"),

            (b)   was further extended to June 30, 1997 pursuant to the Second
                  Amendment to Bridge Loan Conversion and Extension Agreement
                  dated as of March 30, 1997 (the "Second Amendment"),

            (c)   was further extended to require principal payments of $200,000
                  per month beginning on September 15, 1997 pursuant to the
                  Third Amendment to Bridge Loan Conversion and Extension
                  Agreement dated as of June 18, 1997 (the "Third Amendment"),
                  and

            (d)   was further extended to require principal payments of $200,000
                  per month beginning on May 15, 1998 pursuant to the Fourth
                  Amendment to Bridge Loan Conversion and Extension Agreement
                  dated as of September 15, 1997 (the "Fourth Amendment").

References in this Amendment to the "Agreement" refer to the Loan Agreement as
modified by the First Amendment, the Second Amendment, the Third Amendment, and
the Fourth Amendment. Terms used in this Amendment and not otherwise defined
have the meanings given in the Agreement.

            1.2 Agreed Extension. Lender and Borrower have agreed (a) to extend
the due date of the principal owed pursuant to the Agreement to September 15,
1999 (subject to the requirement for principal payments set forth below), (b) in
connection with such extension, to change the interest rate on the Loan to 9%
per annum, and (c) to extend the period for Borrower's exercise of the Option
Shares to September 15, 1999.

      2. Extension Agreement. Lender extends the due date for the balance of the
Loan to September 15, 1999, subject to the requirement that Borrower make
principal payments of $200,000 on each of May 15, June 15, July 15, and August
15, 1999. The Note is amended to conform to this extension and principal payment
schedule

      3. New Interest Rate. The interest rate on the Loan is changed, effective
as of May
<PAGE>   2
15, 1998, to 9% per annum, payable at the times provided in the Agreement and
Note. If Borrower fails to make any principal payment when due, then (a)
Borrower will within 30 days after notice from Lender meet with Lender to
discuss Borrower's business prospects and plans for payment and (b) Lender may,
by written notice to Borrower, increase the interest rate on the Loan by up to
2% per annum above the rate otherwise payable under the Note and this Amendment.
The Note is amended to conform to this change in the interest rate and the
default interest rate.

      4. Extension for Repayment of Principal and Option. The first sentence of
section 5 of the Agreement is amended to read "Borrower will pay the principal
on the Note on or before September 15, 1999, with earlier principal payments as
required in this Agreement." Borrower will continue to have the option to
purchase the Option Shares at any time before repayment of the Note by Borrower,
with the option expiring pro-rata with each reduction in principal. Borrower
will give Lender notice of repayment, and an opportunity to exercise the option,
before repaying the Loan. Notwithstanding any other provisions of the Agreement,
the option to purchase the Option Shares will expire on the date the Securities
and Exchange Commission declares effective a registration statement for the
Borrower's Common Stock.

      5. Notice of Sales of Shares. Section 5 of the Agreement is amended to add
the following new sentence: "Borrower will give Lender notice of any proposed
sale of shares to an unaffiliated third party, at least 30 days before the sale
is consummated."

      6. Continued Effectiveness of Agreement. Except as expressly amended by
this Amendment, the Agreement and the Note continue in full force and effect.

      7. Effective Date. This Amendment is effective as of May 15, 1998.

                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.


                                       2
<PAGE>   3
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

                              BRIDGE LOAN 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 manufactures high quality auto and
            professional audio equipment, including amplifiers, speakers, "head
            units," and accessories.

      1.2.  Loan. Borrower has sought and, subject to the conditions in this
            agreement, Lender has agreed to provide a $2,000,000 loan to
            Borrower to help finance working capital and general corporate needs
            of Borrower.

      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:

      6.1.  payments of interest when due;
<PAGE>   2
      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.

10.   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

      Borrower of any kind. Any 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 the
      maximum amount permitted by law.

12.   MISCELLANEOUS.

            default or cure at Borrower's expense a default. Any waiver in a

                              ROCKFORD CORPORATION

                           1990 RESTRICTED STOCK GRANT
                             AND TAX LOAN AGREEMENT



Background: The Board of Directors of Rockford Corporation ("Rockford") has
authorized a Fiscal 1990 Restricted Stock Grant Program pursuant to which (1)
certain of the Company's key employees ("Grantees") will be granted shares of
Rockford common stock (the "Stock") in consideration of their past and present
services to the Company if (2) each such Grantee will agree to pay all federal
and state taxes (the "Tax Payments") due on his grant (the "Grant") and (3)
Rockford will make available to each Grantee loans (the "Tax Loans") in amounts
of up to the Grantee's tax obligations. The Stock awarded to each Grantee is to
be restricted with regard to (I) its beneficial ownership by the Grantee and
(II) his right to resell shares of it by the limitations that (i) twenty percent
(20%) of the Stock will vest in the Grantee on June 1, 1990 and additional
twenty percents of the Stock will vest in the Grantee on each anniversary date
thereafter, to and including June 1, 1994, (the "Vesting Dates"), but only if
(ii) the Grantee shall have been employed by Rockford until each such Vesting
Date. The key employee hereafter named has been selected by Rockford's Board of
Directors as one of the proposed Grantees under the 1990 Program, and he is
willing (A) to pay the taxes due upon such Grant and (B) to accept the
conditions of its vesting in him.

NOW THEREFORE, This Agreement made as of June 1, 1990 by and between Rockford
and Douglas Morby (hereinafter "Recipient") in consideration of (X) the Grant of
Stock being made by Rockford to Recipient, contemporaneous with this Agreement,
and (Y) Recipient's agreement to accept the restrictions and to make the Tax
Payments associated with his Grant, and with both parties intending to be
legally bound hereby, W I T N E S S E T H that Rockford and Recipient have
agreed as follows:

            First: Stock Grant - Rockford hereby grants to Recipient as a bonus
1,496 shares of Stock and will deliver to Recipient a certificate for such
Stock, restricted as hereinafter recited, contemporaneous with the execution of
this Agreement.

            Second: Acceptance of Grant - Recipient hereby agrees to accept the
Grant as a transfer for, and in consideration of, his past and present services
to the corporation, but subject to his making the Tax Payments and observing the
restrictions upon the vesting and transfer of the Stock Grant, as hereinafter
recited.

            Third: Vesting of Stock - The ownership of the Stock shall vest in
Recipient 300 shares on the effective date hereof, 299 shares on June 1, 1991,
299 shares on June 1, 1992, 299 shares on June 1, 1993 and 299 shares on June 1,
1994, provided that Recipient shall have been continuously employed by Rockford
between the effective date hereof and each such Vesting Date (or, if not
continuously employed, then on temporary, compulsory service in the armed forces
of the United States during any gap in employment). If Recipient leaves
Rockford's employ at any time between the effective date of this Agreement and
June 1, 1994

<PAGE>   2
(other than to serve on active duty in the U.S. armed forces) all Stock not then
vested in him pursuant to the provisions of this Agreement shall be forfeited,
and a new certificate for all vested Stock shall be issued by Rockford to
Recipient.

            Fourth: Tax Payments - Recipient hereby agrees to reimburse to
Rockford all withholdings and to make all additional payments required to pay
the Tax Payments with respect to his Grant by the U.S. Internal Revenue Code,
the Social Security Act and/or any applicable State tax code, all in accordance
with the regulations of each, whether through current withholdings from
Recipient's salary or in lump sum amounts when required tax payments fall due
subsequently.

            Fifth: Tax Loans & Notes - Rockford hereby agrees, at any time when
the Stock cannot be publicly traded, to make available to Recipient
contemporaneous loans in amounts equal to as much as all of the Tax Payments to
be withheld from, or paid by, Recipient pursuant to Fourth hereof, provided that
(A) Recipient shall execute and deliver to Rockford promissory notes
("Note(s)"), in the forms hereto attached and made a part hereof, agreeing to
repay the principal amount of any loan(s) on or before the earliest of the
following dates: May 31, 1993 (_____), May 31, 1995 (_____), or within 180 days
following the first day when the Stock shall have been registered with the
Securities & Exchange Commission and become publicly tradable on NASDAQ or any
registered securities exchange, together with interest thereon at the applicable
federal rate at the time of the making and issuance of any such Note. All such
Notes shall be secured by a pledge of all of the Recipient's Stock as collateral
security for payment in full of all principal and interest due to Rockford
thereunder, which pledge shall be effected by delivery of the certificate for
Recipient's Stock to Rockford with blank stock power attached.

            Sixth: Investment Representations - In order to induce the issuance
of 1,496 shares of Stock by Rockford to Recipient, Recipient hereby represents
and warrants to Rockford that in connection with his acceptance of the Stock
Recipient has relied only upon Recipient's own investigation and knowledge of
Rockford. Recipient has such knowledge and experience in business and financial
matters that Recipient is capable of evaluating Rockford's business and the
risks and merits of the accepting the Stock. Recipient is capable of bearing
whatever degree of economic risk may be involved in acceptance of the Stock,
including but not limited to the possibility of a complete loss of the Tax
Payments made by Recipient in connection with his acceptance of the Stock and
the restrictions upon resale and the lack of any public market which may make it
impossible to readily liquidate the Stock. Recipient has had the opportunity, at
no expense and minimal inconvenience, to ask questions of and seek additional
information from Rockford; and Rockford has provided satisfactory answers
concerning the Company, its business, and the Stock. There is no additional
information the Recipient wishes to obtain from Rockford, or from any other
source, with respect to his acceptance of the Stock and agreement to make the
Tax Payments in connection with such acceptance.

            Recipient also hereby represents and warrants, and in accepting the
Stock it is understood and agreed, that the Recipient is acquiring the Stock for
his own account and not with a view to, or for sale in connection with, any
distribution, and that he has no present intention of distributing any of the
same. In addition, the undersigned acknowledges that the Stock has not


                                      -2-
<PAGE>   3
been registered under the Securities Act of 1933 or any applicable State
securities laws on the ground that the issuance to him is exempt from
registration under the Securities Act by virtue of the foregoing investment
representation and the fact that no sale to him is being made by Rockford. The
recipient understands that the stock must be held indefinitely unless and until
the restrictions upon portions thereof lapse and the offer and sale thereof are
registered under the Securities Act and applicable State securities laws or an
exemption from such registration is available. He is aware that the Stock 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 Rockford. Such
information is not now available, and Rockford has no definite plans to make
such information available in the future. The Recipient also agrees that, in the
absence of an effective registration statement covering all or any of the Stock,
he will not sell, transfer, or otherwise dispose of such Stock in any manner
inconsistent with his representations in this Section.

            Seventh: Restrictions on Certificates - Rockford and Recipient agree
that any certificate for Stock issued pursuant to this Agreement shall bear the
following legends on the reverse side:

            (1) THE SHARES OF STOCK REPRESENTED HEREBY SHALL NOT VEST IN THE
            BENEFICIAL OWNERSHIP OF THE REGISTERED OWNER OF THIS CERTIFICATE
            UNLESS SUCH OWNER SHALL HAVE BEEN CONTINUOUSLY IN THE EMPLOY OF
            ROCKFORD CORPORATION (OR ON TEMPORARY, COMPULSORY DUTY IN THE ARMED
            SERVICES OF THE U.S.) FROM THE DATE HEREOF UNTIL EACH OF THE
            FOLLOWING VESTING DATES, AND THEN ONLY WITH RESPECT TO THE NUMBER OF
            SHARES RECITED BESIDE EACH DATE:
