                                     in connection with any resale of the new
                                     notes. A broker-dealer may use this

Special Procedures for
Beneficial Owners...............     If you beneficially own old notes
                                     registered in the name of a broker, dealer,
                                     commercial bank, trust company or other
                                     nominee and you wish to tender your old
                                     notes in the exchange offer, you should
                                     contact the registered holder as soon as
                                     possible and instruct it to tender on your
                                     behalf. If you wish to tender on your own
                                     behalf, you must, before completing and
                                     executing the letter of transmittal for the
                                     exchange offer and delivering your old

                                     properly completed bond power from the
                                     registered holder. The transfer of
                                     registered ownership may take considerable
                                     time.
    
 
   
Guaranteed Delivery Procedure...     You may comply with the delivery procedures

                                     Old Notes -- Guaranteed Delivery" if you

                                     - time will not permit your required

                                       book-entry transfer on time, or

Registration Rights Agreement...     You have the right to exchange the old

                                     substantially identical terms. This
                                     exchange offer is intended to satisfy those
                                     rights. After the exchange offer is

Certain Federal Tax
Consequences....................     With respect to the exchange of the old
                                     notes for the new notes:
    
 
   
                                     - the exchange will not be a taxable event
                                       for U.S. federal income tax purposes,
    
 
   
                                     - you will not recognize any taxable gain
                                       or loss as a result of such exchange,
    
 
   
                                     - you must include interest in gross income
                                       to the same extent as the old notes, and
    
 
   
                                     - your holding period for the new notes
                                       will include the holding period for the
                                       old notes.
    
 
   
Use of Proceeds.................     We will not receive any proceeds from the
                                     exchange of notes pursuant to the exchange
                                     offer.
    
 
   
Exchange Agent..................     We have appointed Bankers Trust Company as
                                     the exchange agent for this exchange offer.
                                     The telephone number of the exchange agent
                                     is (800) 735-7777.
    
 
   
Failure to Exchange will affect
you adversely...................     If you are eligible to participate in the
                                     exchange offer and you do not tender your
                                     old notes, you will not have any further
                                     registration or exchange rights and your
                                     old notes will continue to be subject to
                                     some restrictions on transfer. Accordingly,
                                     the liquidity of the old notes could be
                                     adversely affected.
    
 
   
                               TERMS OF THE NOTES
    
 
   
     The new notes have the same financial terms and covenants as the old notes,
except that the new notes are registered under the Securities Act of 1933. As a
result, the new notes will not bear legends restricting their transfer and will
not contain the registration rights and additional interest provisions contained
in the old notes.

                                     In addition, the indenture limits our
                                     ability to engage in consolidations,
                                     mergers and transfers of substantially all

                                     prohibitions are subject to a number of
                                     important qualifications and exceptions.
    
 
   
Absence of a Public Market for
the New Notes...................     In general, you may freely transfer the new
                                     notes. However, there are exceptions to
                                     this general statement described in this
                                     prospectus under the section "The Exchange
                                     Offer -- Resales of New Notes." In
                                     addition, the new notes will be new
                                     securities for which there will not

                                     development or liquidity of any market for
                                     the new notes may not occur. BT Alex.Brown
                                     Incorporated, the initial purchaser of the
                                     old notes, has advised us that it currently
                                     intends to make a market in the new notes.
                                     However, you should be aware that the
                                     initial purchaser is not obligated to do
                                     so. In the event such a market may develop,
                                     the initial purchaser may discontinue it at
                                     any time without notice. We do not intend
                                     to apply for a listing of the new notes on
                                     any securities exchange or on any automated

                               ABOUT THE COMPANY
 
     The Company designs, manufactures and markets engine-powered tools for use
in both industrial and residential applications, with its two principal product
lines being portable generators and pressure washers. In 1998, as measured by
net sales, the Company believes it was the largest U.S. manufacturer of portable
generator sets and the second largest U.S. manufacturer of consumer pressure
washers, with a domestic market share in each category as follows:

Portable generators...................................         29%
Pressure washers......................................         33%
</TABLE>
 
     The Company sells its portable generators, pressure washers and other
products primarily to home center chains, mass merchants and warehouse clubs as
well as to independent representatives. Since 1961, the Company has been the
major supplier of portable generators to Sears, Roebuck and Co., and has been
one of two suppliers of pressure washers to Sears, both marketed under the
Craftsman(R) label. The Company is also a core supplier of portable generators
and pressure washers, both marketed under the Generac(R) label, to The Home
Depot, Inc., the largest and one of the fastest growing retail home center
chains in North America.
 
     The Company's performance has benefited from strong growth in the
engine-powered tools market as well as favorable demographic trends. Over the
past three years, the Company's net sales have grown at a compound annual rate
of approximately 38%, increasing from $104.8 million in 1995 to $276.4 million
in 1998.
 
     The Company believes that its strength in each product category is the
result of its strategic approach to engineering and manufacturing, its
innovation in product development and its focus on product quality. In addition
to the manufacture of portable generators and pressure washers, the Company
manufactures some of the components for those products, such as alternators,
pressure washer pumps and blow-molded gas tanks. The benefits of this
"strategic" vertical integration for the Company are (1) significant cost
advantages over certain competitors who source components from third party
suppliers and (2) improved operating profitability through the reconfiguration
of production processes and the standardization of components. The Company also
has long-standing customer relationships and a unique, nationwide service
network to build and support its customer base. The Company believes that these
strengths facilitate the Company's ability to serve its increasingly
sophisticated and demanding retail customers.
 
     The Company has been designing, building and marketing portable generators
since its founding in 1959. The principal executive offices of the Company are
located at 1 Generac Way, Jefferson, Wisconsin 53549, telephone (920) 674-3750.

     In computing the ratio of earnings to fixed charges, "earnings" represents
income (loss) before income taxes plus fixed charges. "Fixed charges" consists
of interest, amortization of debt issuance costs and a portion of rent, which is
representative of the interest factor (approximately one-third of rent expense).

                                  RISK FACTORS
 
   
     Holders tendering old notes in the exchange offer should carefully review
the information contained elsewhere in this prospectus and should particularly
consider the matters set forth below.
    
 
   
WE HAVE SUBSTANTIAL EXISTING DEBT WHICH COULD AFFECT US ADVERSELY.
    
 
   
     Primarily because of the July 9, 1998 acquisition of the Portable Products
Division of Generac Corporation, as described in this prospectus under "The
Transaction," we had approximately $214.8 million of debt outstanding as of
March 31, 1999. Our debt service is approximately $28.0 million annually. The
fact that we have so significant an amount of debt has important consequences to
you as a noteholder. Below we have identified for you material risks caused by
the existence of our debt.
    
 
   
     - We may be unable to obtain in the future funds needed for additional
       working capital, capital expenditures and general corporate purposes.
    
 
   
     - A significant portion of our cash flow from operations is dedicated to
       the repayment of our indebtedness, which reduces the amount of cash we
       have available for other purposes.
    
 
   
     - Our ability to adjust to changing market conditions and our ability to
       withstand competition is hampered by the amount of debt we now owe. We
       are more vulnerable in a downturned market or a recession than our
       competitors with less debt.
    
 
   
WE MAY BE UNABLE TO SERVICE OUR DEBT IF WE ARE UNSUCCESSFUL IN IMPLEMENTING OUR
BUSINESS STRATEGY OR REALIZING OUR ANTICIPATED FINANCIAL RESULTS.
    
 
   
     Our ability to repay or refinance our current debt depends on our
successful implementation of our business strategy. Unfortunately, we cannot
assure you that we will be successful in implementing our strategy or in
realizing our anticipated financial results. Our financial and operational
performance depend upon a number of factors, many of which are beyond our
control. These factors include:
    
 
   
     - the current economic and competitive conditions in the engine-powered
       tools industry,
    
 
   
     - any operating difficulties, operating costs or pricing pressures we may
       experience,
    
 
   
     - the failure of our core customers to expand beyond the traditional
       do-it-yourself market and into the commercial contractor markets, and
    
 
   
     - any delays in the introduction of our planned new product categories.
    
 
   
     Our failure to repay our current debt may result in a number of serious
consequences, including (1) a reduction or delay of expansion, (2) a sale of
some of our assets, or (3) a reorganization or recapitalization of the Company.
Any one or more of these consequences could adversely affect your investment in
the notes. For more information about the Company's indebtedness or business
strategy, you should read the information we have included under the captions
"Description of the Senior Secured Credit Facility" and "Business -- Business
Strategy" later in this prospectus.
    
 
                                        9
<PAGE>   12
 
   
THE INDENTURE AND CREDIT FACILITY IMPOSE SIGNIFICANT RESTRICTIONS ON US.
    
 
   
     The indenture under which the old notes were issued and the new notes will
be issued and our credit facility impose significant operating and financial
restrictions on us and our subsidiaries. These restrictions may significantly
limit or prohibit us from engaging in certain transactions, including the
following:
    
 
   
     - borrowing additional money,
    
 
   
     - paying dividends or other distributions to our stockholders,
    
 
   
     - making certain investments,
    
 
   
     - creating certain liens on our assets,
    
 
   
     - selling certain assets currently held by us,
    
 
   
     - entering into transactions with any of our affiliates, and
    
 
   
     - engaging in certain mergers or consolidations.
    
 
   
IN THE EVENT OF A DEFAULT UNDER THE CREDIT FACILITY, THE LENDERS COULD EXERCISE
CERTAIN RIGHTS SO THAT WE MAY BE UNABLE TO PAY INTEREST OR PRINCIPAL ON THE
NOTES THAT YOU HOLD.
    
 
   
     The credit facility we entered into in financing the acquisition of the
Portable Products Division of Generac Corporation requires Generac Portable
Products, LLC to maintain specified financial ratios and satisfy certain
financial tests. Our ability to meet these financial ratios and tests may be
affected by events beyond our control. As a result, we cannot guarantee to you
that we will be able to meet such tests. We have granted the lenders under the
credit facility a first priority lien on substantially all of our assets and the
assets of our affiliates. In the event of a default under the credit facility,
the lenders under the credit facility could foreclose upon the assets securing
the indebtedness and the holders of the notes might not be able to receive any
payments until any payment default was cured or waived, any acceleration was
rescinded, or the indebtedness outstanding under the credit facility was repaid.
    
 
   
     A breach of any of the covenants contained in our credit facility or our
inability to comply with the required financial ratios could result in an event
of default, which would allow the lenders under the credit facility to declare
all borrowings outstanding to be due and payable. In addition, our lenders could
compel us to apply all of our available cash to repay our borrowings or they
could prevent us from making debt service payments on the notes. If the amounts
outstanding under the credit facility or the notes were to be accelerated, we
cannot assure you that our assets would be sufficient to repay in full the money
owed to the banks or to our other debt holders, including you as a noteholder.
Further, the lenders under the credit facility could terminate their commitments
to lend to us. If that does occur, we cannot assure you that we would be able to
make the necessary payments to the lenders and we cannot give you any assurance
that we would be able to find additional alternative financing. Even if we could
obtain additional alternative financing, we cannot assure you that it would be
on terms that are favorable or acceptable to us.
    
 
                                       10
<PAGE>   13
 
   
THE GENERAC PORTABLE PRODUCTS, INC. GUARANTEE DOES NOT PROVIDE MUCH ADDITIONAL
CREDIT SUPPORT FOR THE NOTES.
    
 
   
     Generac Portable Products, Inc. will issue a guarantee of the notes under
which Generac Portable Products, Inc., as primary obligor, will fully and
unconditionally guarantee the payment of the notes when due on a senior
subordinated basis. This guarantee will be subordinated in right of payment to
all senior indebtedness of Generac Portable Products, Inc. and effectively
subordinated to all indebtedness and other liabilities (including trade
payables) of Generac Portable Products, Inc.'s subsidiaries. Since Generac
Portable Products, Inc. is a holding company with no significant operations and
no significant investments in businesses other than the Issuers, this guarantee
by Generac Portable Products, Inc. provides little, if any, additional credit
support for the notes. Investors should not rely on this guarantee in evaluating
an investment in the notes.
    
 
   
FRAUDULENT CONVEYANCE LAWS PERMIT COURTS TO VOID NOTES IN SPECIFIC
CIRCUMSTANCES.
    
 
   
     The incurrence of indebtedness by us, such as the notes, may be subject to
review under federal bankruptcy law or relevant state fraudulent conveyance or
transfer laws if a bankruptcy case or lawsuit is commenced by or on behalf of
our unpaid creditors. In such a case, if a court were to find under such laws
that we had actual intent to defraud or did not receive fair consideration or
reasonably equivalent value for incurring the debt represented by the notes, and
that, at the time we incurred indebtedness (including indebtedness under the
notes), we (1) were insolvent, (2) were rendered insolvent by reason of such
incurrence, (3) were engaged in a business or transaction for which our
remaining assets constituted unreasonably small capital, or (4) intended to
incur, or believed that we would incur, debts beyond our ability to pay such
debts as they matured, then the court could void or subordinate the amounts
owing under the notes to our presently existing and future indebtedness and take
other actions detrimental to the holders of the notes. We believe that at the
time we incurred the indebtedness constituting the notes, we did not meet any of
the criteria that would permit a court to void or subordinate the notes. Our
belief is based upon our analyses of internal cash flow projections and
estimated values of our assets and liabilities. We cannot assure you, however,
that a court would agree with us.
    
 
   
THERE IS NO PUBLIC MARKET FOR THE NOTES, SO RESALES WILL BE RESTRICTED.
    
 
   
     Currently, there is no public market for the new notes or the old notes. We
do not intend to apply for listing of the notes on any securities exchange or on
any automated dealer quotation system. Although the initial purchaser of the old
notes has informed us that it intends to make a market in the notes, it is not
obligated to do so and may discontinue any such market at any time without
notice. In addition, such market making activity may be limited during this
exchange offer or, in the event that the exchange offer is not consummated or
certain other events, the effectiveness of a shelf registration statement
covering resales of old notes. As a result, we can make no assurances to you as
to the development or liquidity of any market for the notes, your ability to
sell the notes, or the price at which you may be able to sell the notes. Future
trading prices of the notes will depend on many factors, including among other
things, prevailing interest rates, our operating results and the market for
similar securities. Historically, the market for securities similar to the
notes, including non-investment grade debt, has been subject to disruptions that
have caused substantial volatility in the prices of such securities. We
    
 
                                       11
<PAGE>   14
 
   
cannot assure you that, if a market develops, it will not be subject to similar
disruptions. Any such disruptions may adversely affect you as a holder of notes.
    
 
   
YOU WILL NOT RECEIVE NOTICE OF DEFECTS WITH RESPECT TO TENDERS OF OLD NOTES.
    
 
   
     Neither the exchange agent nor we are under any duty to give you
notification of defects or irregularities with respect to tenders of old notes
for exchange. If you desire to tender your old notes in exchange for new notes,
you should allow sufficient time to ensure timely delivery to the exchange agent
of all required documentation. Old notes that are not tendered or are tendered
but not accepted will, following the consummation of the exchange offer,
continue to be subject to the existing transfer restrictions.
    
 
   
FAILURE TO EXCHANGE YOUR OLD NOTES MAY AFFECT YOUR ABILITY TO SELL THEM AFTER
THE COMPLETION OF THE EXCHANGE OFFER.
    
 
   
     Old notes will, following the completion of the exchange offer, continue to
be subject to existing transfer restrictions. We will not register any
additional resale of the old notes under the Securities Act of 1933 after the
exchange offer is completed. The trading market for old notes after the
completion of the exchange offer could be adversely affected due to the limited
amount, or "float," of the old notes that are expected to remain outstanding
following the exchange offer. Generally, a lower float of a security could
result in less demand to purchase such security and, as a result, could result
in lower prices for such security.
    
 
   
WE HAVE A LIMITED HISTORY OF INDEPENDENT OPERATIONS AND WE CANNOT PREDICT
WHETHER WE WILL BE AS SUCCESSFUL AS AN INDEPENDENT COMPANY.
    
 
   
     We began independent operations in July 1998, when we purchased our
business and assets. Prior to that date we operated our business as the Portable
Products Division of Generac Corporation, which was a larger company with
broader financial support and administrative systems and services. Therefore, we
do not possess a long history of operating our business and assets as an
independent company and we cannot offer you assurance from prior experience that
we will in the future obtain operating results that are as good as our
historical results.
    
 
   
OUR OPERATING RESULTS MAY SUFFER IF WE CANNOT OBTAIN A SUFFICIENT SUPPLY OF THE
GENERAC ENGINE OR IF WE LOSE THE EXCLUSIVE RIGHT TO USE THE GENERAC ENGINE IN
OUR PRODUCTS.
    
 
   
     We have used the Generac-Nagano overhead valve industrial engine in certain
of our products since 1992. In fiscal 1998, 32.0% of our sales were attributable
to products that incorporated the GN OHVI engine. At the time we purchased the
Portable Products Division of Generac Corporation, we entered into an engine
supply agreement with Generac Corporation. This agreement provides that Generac
Corporation will supply us with the GN OHVI engine on an exclusive basis as long
as we make minimum annual purchases of GN OHVI engines over the next nine years.
Although we believe the terms of the engine supply agreement are fair and
reasonable, we cannot assure you that the engine supply agreement will
adequately provide for our future engine requirements. On the one hand, Generac
Corporation may not be able to supply all the GN OHVI engines we may require,
and on the other, the annual minimum purchase exclusivity threshold may be for a
greater number of engines than what we require in any given year. Our inability
to obtain all of the engines we need or our purchase of more engines than we
need in order to maintain our exclusive right to the engine could adversely
affect our financial
    
 
                                       12
<PAGE>   15
 
   
performance. Also, our purchase in any year of fewer engines than the annual
minimum purchase exclusivity threshold will allow Generac Corporation to supply
the GN OHVI engine to our competitors, which could also adversely affect our
financial performance. Please read the section entitled "Business -- Engine
Supply" later in this prospectus for additional information.
    
 
   
OUR OPERATING RESULTS DEPEND ON OUR RELATIONSHIP WITH OUR THREE LARGEST
CUSTOMERS.
    
 
   
     Our three largest customers, Home Depot, Sears and Costco, accounted for
approximately 74% of our sales for each of 1998 and 1997. We do not have
contractual agreements with any of these customers for the supply of products.
Our customers, including these three largest customers, place orders for our
products on an as-needed basis. As a result, we are particularly dependent upon
a continuing flow of new orders from these large, high volume customers, and our
future growth depends in part on the ability of our customers to increase the
volume of our products they resell. The loss of any of these customers or a
significant decrease in the volume of products supplied to any of these
customers, particularly Home Depot or Sears, could affect our financial
performance in a negative way.
    
 
   
WE MAY NOT BE ABLE TO EFFECTIVELY MANAGE OUR FUTURE GROWTH.
    
 
   
     Over the past three years, our sales have experienced strong growth and we
have significantly expanded our operations. We are currently in the process of
expanding our operations and we expect that further expansion will be required
to realize our growth strategy. This rapid growth places a significant demand on
our management, operational, financial and other resources. In order to manage
our growth effectively, we must implement and improve our operational systems,
procedures and controls. We cannot guarantee that we will be able to manage our
growth effectively or that we will be able to grow in the future at the same
rate we have in the past.
    
 
   
WE FACE SIGNIFICANT COMPETITION, WHICH COULD LIMIT OUR GROWTH, REDUCE OUR MARKET
SHARE AND HARM OUR FINANCIAL PERFORMANCE.
    
 
   
     The introduction of new products and product innovations and other
competitive activities by our competitors may result in our inability to sustain
prior levels of revenues or continue our recent revenue growth. We operate in a
highly competitive environment with numerous domestic and foreign competitors
which are financially strong and capable of competing efficiently with us in the
marketplace. In the manufacture and sale of portable generators, we compete
primarily with Honda Engine Company and Coleman Powermate, a division of The
Coleman Company, Inc. Honda has significantly greater financial and operating
resources and name recognition than we do. In the manufacture and sale of
pressure washers, we compete primarily with DeVilbiss Air Power Company, a
subsidiary of Falcon Building Products, Inc., and, to a lesser extent, with
Alfred Karcher GmBH & Co. and Campbell Hausfeld, a division of The Campbell
Group. Some of our competitors may be willing to reduce prices and accept lower
margins to compete with us. Any of our competitors may be more successful at
developing new products and product innovations. In addition, we compete with
these competitors not only for consumer acceptance but also to establish and
maintain relationships with the major retail home centers and
do-it-yourself-retailers, most of which distribute only a single competitor's
product.
    
 
                                       13
<PAGE>   16
 
   
BECAUSE WE DEPEND ON TWO MANUFACTURING FACILITIES, ANY DISRUPTION IN THEIR
OPERATIONS COULD AFFECT US ADVERSELY.
    
 
   
     We produce all of our United States products in our manufacturing facility
located in Jefferson, Wisconsin. We produce all of the products required for our
European operations at our manufacturing facility located in Cheshire, England.
Our manufacturing processes are highly complex and require sophisticated and
costly equipment. As a result, any prolonged interruption in the operations of
either of our manufacturing facilities could result in delays or cancellations
of shipments. A number of factors could cause interruptions, including labor
difficulties, equipment failures or destruction of or damage to a facility. We
cannot assure you that alternative qualified capacity would be available on a
timely basis or at all. Interruptions could result in a loss of customers and
could affect our financial performance in a negative way.
    
 
   
WE MAY FACE ADDITIONAL COSTS AND OTHER ADVERSE EFFECTS DUE TO YEAR 2000 COMPUTER
PROBLEMS.
    
 
   
     Year 2000 issues exist when years in dates are recorded in computers using
two digits (rather than four) and are then used for arithmetic operations,
comparisons or sorting. The two-digit year "00" may be recognized as 1900 rather
than 2000, which could cause our computer systems to perform inaccurate
computations. We have adopted a three phase approach of assessment, correction
and testing. Although we have not yet completed our Year 2000 project, we
currently estimate that our information technology systems will be Year 2000
compliant by September 1, 1999. You should be aware that Year 2000 issues relate
not only to our systems, but also to those used by our suppliers. We anticipate
that system replacements and modifications will resolve any Year 2000 issues
that may exist with our suppliers or their suppliers. However, we cannot
guarantee to you that such replacements or modifications will be completed
successfully or on time and, as a result, any failure to complete such
modification on time may materially affect our financial and operating results
in a negative way. You should read the section "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Year 2000 Strategy"
later in this prospectus for additional information.
    
 
   
IF WE LOSE KEY PERSONNEL, OUR ABILITY TO MANAGE WILL BE WEAKENED.
    
 
   
     Our continued success is highly dependent upon the personal efforts and
abilities of our senior management, including Dorrance J. Noonan, Jr., our
President and Chief Executive Officer, Gary J. Lato, our Chief Financial
Officer, and James H. Deneffe, our Senior Vice President of Sales and Marketing.
We do not have employment contracts with any of these officers and the loss of
any one of them could impact us in a negative way. Please also read the
"Management" section later in this prospectus for additional information.
    
 
   
OUR ACTUAL RESULTS MAY DIFFER MATERIALLY FROM THOSE ANTICIPATED IN OUR FORWARD-
LOOKING STATEMENTS.
    
 
   
     This prospectus contains certain forward-looking statements concerning our
operations, economic performances and financial condition. These statements are
based upon a number of assumptions and estimates which are inherently subject to

                                  THE ISSUERS
 
   
     Generac Portable Products, Inc., a Delaware corporation, and its
subsidiaries, is a leader in the design, manufacture and sales of portable
generators and pressure washers as described under "Business." Generac Portable
Products, Inc. was formed on April 29, 1998 as a Delaware corporation. The
primary business activity of Generac Portable Products, Inc. consists of its
indirect ownership of 100% of the limited liability company interests in Generac
Portable Products, LLC, a Delaware limited liability company. This interest is

and GPPD, Inc., a Delaware corporation. GPPD, Inc. holds 95% of the limited
liability company interests in Generac Portable Products, LLC and GPPW, Inc.

     GPPD, Inc. was incorporated in Delaware on May 19, 1998 and GPPW, Inc. was
incorporated in Wisconsin on May 28, 1998. Neither GPPD, Inc. nor GPPW, Inc.

the cash flow and assets of Generac Portable Products, LLC for payment of the
notes.
    
 
   
     Generac Portable Products, LLC was formed on June 1, 1998 as a Delaware
limited liability company. On July 9, 1998, Generac Portable Products, LLC
acquired the production, marketing, sales, engineering, research and development
(and in the U.K., Spain and Germany, importation) and administration operations
of Generac Corporation's Portable Products Division located at its facilities in
Wisconsin, England, Spain and Germany.
    
 
     The principal executive offices of the Issuers are located at 1 Generac

                                THE TRANSACTION
 
   
     On May 5, 1998, Generac Portable Products, Inc. and Generac Corporation
entered into an Asset Purchase and Sale Agreement pursuant to which Generac
Portable Products, Inc. caused Generac Portable Products, LLC to purchase
substantially all of the assets, and assume certain of the liabilities, of
Generac Corporation's Portable Products Division.
    
 
                                       15
<PAGE>   18
 
   
The purchase price was $305.5 million in cash after post closing adjustments
estimated to total $1.0 million. In connection with this transaction, The Beacon
Group III -- Focus Value Fund, L.P., certain members of management of the
Company and certain other investors purchased an aggregate of $110.0 million of
common stock of Generac Portable Products, Inc., constituting 100% of the
outstanding Generac Portable Products, Inc. common stock.
    
 
   
     Generac Portable Products, LLC entered into a new bank credit facility in
connection with this transaction that provided for (1) two senior secured term
loan facilities in the aggregate amount of $85.0 million and (2) a senior
secured revolving credit facility of up to $30.0 million. At the closing, $85.0
million was borrowed under the term loans and $11.6 million was borrowed under
the revolving credit facility to fund this transaction. The total borrowings of
$96.6 million were subsequently reduced by $2.4 million on account of post
closing adjustments and a refund of an overpayment of transaction expenses.
Additionally, Generac Portable Products, LLC entered into a capital lease
arrangement with Generac Corporation for manufacturing equipment with a fair
value of approximately $2.6 million.
    
 
   
     The acquisition of the Portable Products Division of Generac Corporation by
Generac Portable Products, LLC, the borrowings by Generac Portable Products, LLC
of funds under the credit facility, the equity investment by The Beacon Group,
management and other investors, the capital lease and the issuance of the old
notes are referred to in this prospectus collectively as the "Transaction."

     This exchange offer is intended to satisfy our obligations under the
Registration Rights Agreement dated as of July 2, 1998 between us and BT Alex.
Brown Incorporated, the initial purchaser of the old notes. We will not receive
any proceeds from the issuance of the new notes offered by this prospectus. In
consideration for issuing the new notes in exchange for old notes as described
in this prospectus, we will receive old notes in the same principal amount. The
old notes surrendered in exchange for the new notes will be retired and canceled
and cannot be reissued. As a result, the issuance of the new notes will not
result in any increase in our outstanding debt.

                               THE EXCHANGE OFFER
 
   
BACKGROUND
    
 
   
     The Issuers originally sold the outstanding old notes on July 9, 1998, in a
transaction exempt from the registration requirements of the Securities Act. BT
Alex. Brown Incorporated, as the initial purchaser, subsequently resold the
notes to qualified institutional buyers in reliance on Rule 144A under the
Securities Act of 1933. As of the date of this prospectus, $110.0 million
aggregate principal amount of unregistered notes are outstanding.
    
 
   
     The Issuers and BT Alex. Brown Incorporated entered into the registration
rights agreement under which the Issuers agreed that they would, at their own
cost,
    
 
   
     - file an exchange offer registration statement under the Securities Act of
       1933 on or before February 4, 1999, 210 days after the original issue
       date of the old notes, and
    
 
   
     - use their reasonable best efforts to cause the exchange offer
       registration statement to become effective under the Securities Act at
       the earliest possible time, but no later than April 5, 1999, 270 days
       after the original issue date of the old notes, otherwise the interest
       note borne by the old notes will increase by 0.50% per annum until the
       exchange offer is consummated.
    
 
   
     The registration statement of which this prospectus is a part was filed on
March 3, 1999 and was declared effective on [             ], 1999. As a result,
the Issuers were subject to the increased interest rate for a total of [  ]
days.
    
 
   
     The exchange offer is being made to satisfy the contractual obligations of
the Issuers under the registration rights agreement. The summary in this
prospectus of the material provisions of the registration rights agreement does
not purport to be complete and is subject to, and is qualified in its entirety
by, all the provisions of the registration rights agreement, a copy of which is
filed as an exhibit to the Registration Statement of which this prospectus is a
part.
    
 
   
     The exchange offer is not being made to, nor will the Issuers accept
tenders for exchange from, holders of old notes in any jurisdiction in which the
exchange offer or the acceptance thereof would not be in compliance with the
securities or blue sky laws of such jurisdiction.
    
 
   
     Unless the context requires otherwise, the term "holder" with respect to
the exchange offer means any person in whose name the old notes are registered
on the books of the Issuers or any other person who has obtained a properly
completed bond power from the registered holder, or any person who beneficially
owns old notes which are held of record by DTC, who desires to deliver such old
notes by book-entry transfer into the exchange agent's account at DTC, or any
person who beneficially owns old notes which are held of record by a nominee
other than DTC, or its nominee.
    
 
   
TERMS OF THE EXCHANGE OFFER
    
 
   
     As soon as practicable after the date the exchange offer registration
statement is declared effective, the Issuers will offer up to $110,000,000
aggregate principal amount of new notes in exchange for surrender of a like
principal amount of old notes. The Issuers will keep the exchange offer open for
at least 30 days, or longer if required by applicable law, after the date notice
of the exchange offer is mailed to the holders of the old notes.
    
 
                                       18
<PAGE>   21
 
   
     Upon the terms and subject to the conditions contained in this prospectus
and in the letter of transmittal which accompanies this prospectus, Issuer will
accept any and all old notes validly tendered and not withdrawn before 5:00
p.m., New York City time, on the expiration date of the exchange offer. The
Issuers will issue an equal principal amount of up to $110,000,000 of new notes
in exchange for the principal amount of old notes accepted in the exchange
offer. Holders may tender some or all of their old notes under the exchange
offer. Old notes may be tendered only in integral multiples of $1,000. The
exchange offer is not conditioned on any minimum principal amount of old notes
being tendered.
    
 
   
     The form and terms of the new notes will be the same as the form and terms
of the old notes except that:
    
 
   
     - the new notes will have been registered under the Securities Act and
       therefore will not bear legends restricting their transfer, and
    
 
   
     - the new notes will not contain certain terms providing for an increase in
       the interest rate on the old notes under specific circumstances which are
       described in the registration rights agreement.
    
 
   
The new notes will evidence the same debt as the old notes and will be entitled
to the benefits of the Indenture governing the old notes.
    
 
   
     In connection with the exchange offer, holders of old notes do not have any
appraisal or dissenters' rights under law or the indenture governing the old
notes. Old notes which are not tendered for or are tendered but not accepted in
connection with the Exchange Offer will remain outstanding and remain entitled
to the benefits of the Indenture, but will not be entitled to any further
registration rights under the registration rights agreement, except under
limited circumstances. The Issuers intend to conduct the exchange offer in
accordance with the applicable requirements of the Exchange Act of 1934 and the
rules and regulations of the SEC related to such offers.
    
 
   
     The Issuers shall be deemed to have accepted validly tendered old notes
when, as and if the Issuers have given oral or written notice of acceptance to
Bankers Trust Company, exchange agent for the exchange offer. The exchange agent
will act as agent for the tendering holders for the purpose of receiving the new
notes from the Issuers.
    
 
   
     If any tendered old notes are not accepted for exchange because of an
invalid tender, because of the occurrence of certain other events specified in
this prospectus, or if old notes are submitted for a greater principal amount
than the holder desires to exchange, the certificates for the unaccepted old
notes will be returned without expense to the tendering holder promptly after
the expiration date. If old notes were tendered by book-entry transfer in the
exchange agent account at DTC in accordance with the book-entry transfer
procedures described below, these non-exchanged old notes will be credited to an
account maintained with DTC as promptly as practicable after the expiration date
of the exchange offer.
    
 
   
     The Issuers will pay all charges and expenses, other than transfer taxes in
certain circumstances, in connection with the exchange offer. Holders who tender
old notes in the exchange offer will therefore not need to pay brokerage
commissions or fees or, subject to the instructions in the letter of
transmittal, transfer taxes with respect to the exchange of old notes in the
exchange offer. See "-- Fees and Expenses."
    
 
   
     THE RESPECTIVE BOARDS OF DIRECTORS OF THE ISSUERS MAKE NO RECOMMENDATION TO
HOLDERS OF OLD NOTES AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ALL OR
ANY PORTION OF THEIR
    
 
                                       19
<PAGE>   22
 
   
OLD NOTES PURSUANT TO THE EXCHANGE OFFER. IN ADDITION, NO ONE HAS BEEN
AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION. HOLDERS OF OLD NOTES MUST MAKE THEIR
OWN DECISION WHETHER TO TENDER PURSUANT TO THE EXCHANGE OFFER AND, IF SO,
DETERMINE THE AGGREGATE PRINCIPAL AMOUNT OF OLD NOTES TO TENDER AFTER READING
THIS PROSPECTUS AND THE LETTER OF TRANSMITTAL AND CONSULTING WITH THEIR
ADVISERS, IF ANY, BASED ON THEIR OWN FINANCIAL POSITION AND REQUIREMENTS.
    
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
   
     The expiration date of the exchange offer is 5:00 p.m., New York City time,
on              , 1999, unless the Issuers, in their reasonable discretion,
extend the exchange offer, in which case the expiration date shall be the latest
date and time to which the exchange offer is extended.
    
 
   
     In order to extend the exchange offer, the Issuers will notify the exchange
agent of any extension by oral or written notice and will make a public
announcement of the extension before 9:00 a.m., New York City time, promptly
confirmed in writing, on the next business day after the previously scheduled
expiration date.
    
 
   
     The Issuers reserve the right, in their reasonable discretion, subject to
applicable law:
    
 
   
     - to delay accepting any old notes,
    
 
   
     - to terminate the exchange offer if, in their reasonable judgement, any of
       the conditions described below under "-- Conditions" shall not have been
       satisfied,
    
 
   
     - to extend the expiration date and retain all old notes tendered for the
       exchange offer, subject to the right of holders of old notes to withdraw
       their tendered old notes as described under "-- Withdrawal Rights", or
    
 
   
     - to waive any condition or to amend the terms of the exchange offer in any
       manner.
    
 
   
     If the exchange offer is amended in a manner determined by the Issuers to
constitute a material change, or if the Issuers waive a material condition of
the exchange offer, the Issuers will promptly disclose such amendment by means
of a prospectus supplement that will be distributed to the registered holders of
the old notes, and the Issuers will extend the exchange offer to the extent
required by Rule 14e-1 under the Exchange Act of 1934. The Issuers will promptly
announce any such event by making a timely release to Dow Jones News Service,
and may or may not do so by other means as well.
    
 
ACCEPTANCE FOR EXCHANGE AND ISSUANCE OF NEW NOTES
 
   
     Upon the terms and subject to the conditions of the exchange offer, the
Issuers will exchange new notes for old notes validly tendered and not
withdrawn, pursuant to the withdrawal rights described under "-- Withdrawal
Rights," promptly after the expiration date.
    
 
   
     Subject to the conditions set forth under "-- Conditions to the Exchange
Offer," delivery of new notes in exchange for old notes tendered and accepted
for exchange according to the terms of the exchange offer will be made only
after timely receipt by the exchange agent of:
    
 
   
     - certificates for old notes or a book-entry confirmation of a book-entry
       transfer of old notes into the exchange agent's account at DTC, including
       an agent's message if the tendering holder does not deliver a letter of
       transmittal,
    
 
                                       20
<PAGE>   23
 
   
     - a completed and signed letter of transmittal, or facsimile, with any
       required signature guarantees, or, in the case of a book-entry transfer,
       an agent's message, and
    
 
   
     - any other documents required by the letter of transmittal.
    
 
   
     Accordingly, the delivery of new notes might not be made to all tendering
holders at the same time, and will depend upon when certificates for old notes,
book-entry confirmations with respect to old notes and other required documents
are received by the exchange agent.
    
 
   
     The term "book-entry confirmation" means a timely confirmation of a
book-entry transfer of old notes into the exchange agent's account at DTC. See
"-- Procedures for Tendering -- Book-Entry Transfer."
    
 
   
     The term "agent's message" means a message transmitted by DTC to, and
received by, the exchange agent, which states that DTC has received an express
acknowledgment from the participant in DTC tendering the old notes stating:
    
 
   
     - the aggregate principal amount of old notes which have been tendered by
       such participant,
    
 
   
     - that such participant has received and agrees to be bound by the terms of
       the letter of transmittal, and
    
 
   
     - that the Issuers may enforce such agreement against the participant.
    
 
   
     Subject to the terms and conditions of the exchange offer, the Issuers will
be deemed to have accepted for exchange, and to have exchanged, old notes
validly tendered and not withdrawn when the Issuers give oral or written notice
to the exchange agent of the Issuers' acceptance of such old notes for exchange
pursuant to the exchange offer, promptly confirmed in writing. The exchange
agent will act as agent for the Issuers for the purpose of receiving tenders of
old notes, letters of transmittal and related documents, and as agent for
tendering holders for the purpose of receiving old notes, letters of transmittal
and related documents and transmitting new notes which will not be held in
global form by DTC or a nominee of DTC to validly tendering holders. Such
exchange will be made promptly after the expiration date. If for any reason
whatsoever, acceptance for exchange or the exchange of any old notes tendered
pursuant to the exchange offer is delayed, whether before or after the Issuers'
acceptance for exchange of old notes, or the Issuers extend the exchange offer
or are unable to accept for exchange or exchange old notes tendered pursuant to
the exchange offer, then, without prejudice to the Issuers' rights set forth
herein, the exchange agent may nevertheless, on behalf of the Issuers and
subject to Rule 14e-1(c) under the Exchange Act of 1934, retain tendered old
notes and such old notes may not be withdrawn except to the extent that
tendering holders are entitled to withdrawal rights as described under
"-- Withdrawal of Tenders."
    
 
   
     Pursuant to an agent's message or a letter of transmittal, a holder of old
notes will represent, warrant and agree in the agent's message or letter of
transmittal that:
    
 
   
     - it has full power and authority to tender, exchange, sell, assign and
       transfer old notes,
    
 
   
     - the Issuers will acquire good, marketable and unencumbered title to the
       tendered old notes, free and clear of all liens, restrictions, charges
       and encumbrances, and
    
 
   
     - the old notes tendered for exchange are not subject to any adverse claims
       or proxies.

     The holder will also warrant and agree that it will, upon request, execute
and deliver any additional documents deemed by the Issuers or the exchange agent
to be necessary or desirable to complete the exchange, sale, assignment, and
transfer of the old notes tendered pursuant to the exchange offer.
    
 
PROCEDURES FOR TENDERING
 
   
     You may tender your own old notes in the exchange offer. To tender in the
exchange offer, a holder must do the following:
    
 
   
     - complete, sign and date the letter of transmittal, or a facsimile of the
       letter of transmittal,
    
 
   
     - have the signatures thereon guaranteed if required by the letter of
       transmittal, and
    
 
   
     - except as discussed in "-- Guaranteed Delivery Procedures," mail or
       otherwise deliver the letter of transmittal, or facsimile, together with
       the old notes and any other required documents, to the exchange agent
       prior to 5:00 p.m., New York City time, on the expiration date of the
       exchange offer.
    
 
   
     The exchange agent must receive the old notes, a completed letter of
transmittal and all other required documents at one of the addresses listed
below under "-- Exchange Agent" before 5:00 p.m., New York City time, on the
expiration date for the tender to be effective. You may deliver your old notes
by using the book-entry transfer procedures described below, as long as the
exchange agent receives confirmation of the book-entry transfer before the
expiration date.
    
 
   
     DTC has authorized its participants that hold old notes on behalf of
beneficial owners of old notes through DTC to tender their old notes as if they
were holders. To effect a tender of old notes, DTC participants should either:
    
 
   
     - complete and sign the letter of transmittal, or facsimile, have the
       signature thereon guaranteed if required by the instructions to the
       letter of transmittal, and mail or deliver the letter of transmittal, or
       facsimile, to the exchange agent according to the procedure described in
       "Procedures for Tendering" or
    
 
   
     - transmit their acceptance to DTC through its automated tender offer
       program for which the transaction will be eligible and follow the
       procedure for book-entry transfer as described in "-- Book-Entry
       Transfer."
    
 
   
     By tendering, each holder will make the representations contained in the
fourth paragraph below under the heading "-- Resales of the New Notes." Each
participating broker-dealer must acknowledge that it will deliver a prospectus
in connection with any resale of such new notes. See "Plan of Distribution."
    
 
   
     The tender by a holder according to any of the described procedures and the
acceptance of the tender by the Issuers will constitute a binding agreement
between the holder and the Issuers upon the terms and subject to the conditions
of the exchange offer.
    
 
   
     If less than all old notes are tendered, a tendering holder should fill in
the amount of old notes being tendered in the appropriate box on the letter of
transmittal. The entire amount of old notes delivered to the exchange agent will
be deemed to have been tendered unless otherwise indicated.
    
 
   
     THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND SOLE RISK
OF THE HOLDER AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY
THE EXCHANGE AGENT. AS
    
 
                                       22
<PAGE>   25
 
   
AN ALTERNATIVE TO DELIVERY BY REGISTERED MAIL WITH RETURN RECEIPT REQUESTED AND
PROPERLY INSURED, HOLDERS MAY WISH TO CONSIDER OVERNIGHT OR HAND DELIVERY
SERVICE. IN ALL CASES, HOLDERS SHOULD ALLOW SUFFICIENT TIME TO ASSURE DELIVERY
TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR
OLD NOTES OR BOOK-ENTRY CONFIRMATION SHOULD BE SENT TO THE ISSUERS. HOLDERS MAY
REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR
NOMINEES TO EFFECT THE ABOVE TRANSACTIONS ON THEIR BEHALF.
    
 
   
     Any beneficial owner whose old notes are held by or registered in the name
of a broker, dealer, commercial bank, trust company or other nominee or
custodian and who wishes to tender should contact the registered holder promptly
and instruct it to tender on the beneficial owner's behalf. See "Instructions to
Registered Holder and/or Book-Entry Transfer Facility Participant from
Beneficial Owner" included with the letter of transmittal. If the beneficial
owner wishes to tender on his own behalf, such owner must, prior to completing
and executing the letter of transmittal and delivering such beneficial owner's
old notes, either make appropriate arrangements to register ownership of the old
notes in such owner's name or obtain a properly completed bond power from the
registered holder. The transfer of registered ownership may take considerable
time.
    
 
   
     Certificates for old notes need to be endorsed and signatures on a letter
of transmittal or a notice of withdrawal must be guaranteed by an eligible
guarantor institution unless the old notes are tendered:
    
 
   
     - by a registered holder who has not completed the box entitled "Special
       Issuance Instructions" or "Special Delivery Instructions" on the letter
       of transmittal, or
    
 
   
     - the certificate for the old notes is registered in the same name as the
       person surrendering the certificate.
    
 
   
     This means that such certificates for old notes must be duly endorsed or
accompanied by a properly executed bond power, with endorsement or signature on
the bond power and on the letter of transmittal guaranteed by a firm or other
entity identified in Rule 17Ad-15 under the Exchange Act of 1934 as an "eligible
guarantor institution," including: a bank, a broker, dealer, municipal
securities broker or dealer or government securities broker or dealer, a credit
union, a national securities exchange, registered securities association or
clearing agency, or a savings association that is a participant in a Securities
Transfer Association (each, an "eligible institution"), unless surrendered on
behalf of such eligible institution.
    
 
   
     If any letter of transmittal, endorsement, old note, bond power, power of
attorney or any other document required by the letter of transmittal is signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by Issuer, evidence
satisfactory to the Issuers of their authority to so act must be submitted with
the letter of transmittal.
    
 
   
     All questions as to the validity, form, eligibility, including time of
receipt, acceptance of tendered old notes and withdrawal of tendered old notes
will be determined by the Issuers in their sole discretion, which determination
will be final and binding. The Issuers reserve the absolute right to reject any
and all old notes not properly tendered or any old notes the Issuers' acceptance
of which would, in the opinion of counsel for the Issuers, be unlawful. The
Issuers also reserve the absolute right, subject to applicable law, to waive any
defects, irregularities or conditions of tender as to particular old notes. The
Issuers' interpretation of the terms and conditions of the exchange offer,
including the instructions in the letter of transmittal, will be final and
binding on all parties. Unless waived, any
    
 
                                       23
<PAGE>   26
 
   
defects or irregularities in connection with tenders of old notes must be cured
within a period of time that the Issuers shall determine. Neither the Issuers,
the exchange agent nor any other person shall be under any duty to give any
notification of any defects or irregularities or shall incur any liability for
failure to give notice of any defect or irregularity with respect to any tender
of old notes. Tenders of old notes will not be deemed to have been made until
such defects or irregularities mentioned above have been cured or waived. Any
old notes received by the exchange agent that are not properly tendered and as
to which the defects or irregularities have not been cured or waived will be
returned by the exchange agent to the tendering holders, unless otherwise
provided in the letter of transmittal, as soon as practicable following the
expiration date of the exchange offer.
    
 
   
BOOK-ENTRY TRANSFER
    
 
   
     The exchange agent and the book-entry transfer facility, DTC, have
confirmed that any participant in DTC's book-entry transfer facility system may
use DTC's automated tender offer procedures to tender old notes. Within two
business days after the date of this prospectus, the exchange agent will
establish a new account or utilize an existing account with respect to the old
notes at DTC, for the purpose of facilitating the exchange offer. Subject to the
establishment of the accounts, any financial institution that is a participant
in the book-entry transfer facility's system may make book-entry delivery of old
notes by causing the book-entry transfer facility to transfer the old notes into
the exchange agent's account with respect to the old notes in accordance with
that facility's procedures. Although delivery of the old notes may be effected
through book-entry transfer into the exchange agent's account at the book-entry
transfer facility, this procedure requires that an appropriate letter of
transmittal properly completed and duly executed or an agent's message with any
required signature guarantee and all other required documents must be delivered
to the exchange agent at its address listed below on or before the expiration
date of the exchange offer, or, if the guaranteed delivery procedures described
below are complied with, within the time period provided under such procedures.
    
 
   
     Delivery of documents to DTC in accordance with its procedures does not
constitute delivery to the exchange agent.
    
 
   
GUARANTEED DELIVERY PROCEDURES
    
 
   
     A holder who wishes to tender its old notes and:
    
 
   
     - whose old notes are not immediately available,
    
 
   
     - who cannot deliver the holder's old notes, the letter of transmittal or
       any other required documents to the exchange agent prior to the
       expiration date, or
    
 
   
     - who cannot complete the procedures for book-entry transfer before the
       expiration date,
    
 
   
may effect a tender if:
    
 
   
     - the tender is made by or through an eligible guarantor institution,
    
 
   
     - on or before the expiration date, the exchange agent receives from the
       eligible guarantor institution a properly completed and duly executed
       notice of guaranteed delivery by facsimile transmission, mail or hand
       delivery, substantially in the form accompanying the letter of
       transmittal, and including a guarantee by an eligible institution, and
    
 
                                       24
<PAGE>   27
 
   
     - the exchange agent receives, within three New York Stock Exchange trading
       days after the date of execution of such notice of guaranteed delivery, a
       properly completed and executed letter of transmittal or facsimile, as
       well as the certificate(s) representing all tendered old notes in proper
       form for transfer or a confirmation of book-entry transfer of such old
       notes and an agent's message instead of a letter of transmittal with any
       required signature guarantees and all other documents required by the
       letter of transmittal.
    
 
   
RESALES OF THE NEW NOTES
    
 
   
     Based on no-action letters issued by the staff of the SEC to third parties,
the Issuers believe that a holder of old notes, but not a holder who is an
affiliate of the Issuers within the meaning of Rule 405 of the Securities Act of
1933, who exchanges old notes for new notes in the exchange offer generally may
offer the new notes for resale, sell the new notes and otherwise transfer the
new notes without further registration under the Securities Act and without
delivery of a prospectus that satisfies the requirements of Section 10 of the
Securities Act. This does not apply, however, to a holder who is an affiliate of
the Issuers within the meaning of Rule 405 of the Securities Act. Any holder of
old notes who is an affiliate of the Issuers or who intends to participate in
the exchange offer for the purpose of distributing new notes, or any
broker-dealer who purchased old notes from the Issuers to resell pursuant to
Rule 144A or any other available exemption under the Securities Act:
    
 
   
     - will not be able to rely on the interpretations of the SEC staff set
       forth in the above-mentioned interpretive letters,
    
 
   
     - will not be permitted or entitled to tender such old notes in the
       exchange offer, and
    
 
   
     - must comply with the registration and prospectus delivery requirements of
       the Securities Act in connection with any sale or other transfer of such
       old notes unless such sale is made pursuant to an exemption from such
       requirements.
    
 
   
The Issuers also believe that a holder may offer, sell or transfer the new notes
only if the holder acquires the new notes in the ordinary course of its business
and is not participating, does not intend to participate and has no arrangement
or understanding with any person to participate in a distribution of the new
notes. However, the Issuers have not sought their own interpretive letter and
there can be no assurance that the SEC staff would make a similar determination
with respect to the Exchange Offer as it has in such interpretive letters to
third parties.
    
 
   
     Any holder of old notes using the exchange offer to participate in a
distribution of new notes cannot rely on the no-action letters referred to
above. This includes a broker-dealer that acquired old notes directly from the
Issuers, but not as a result of market-making activities or other trading
activities. Consequently, the holder must comply with the registration and
prospectus delivery requirements of the Securities Act in the absence of an
exemption from such requirements.
    
 
   
     Each broker-dealer that receives new notes for its own account in exchange
for old notes, where such old notes were acquired by the broker-dealer as a
result of market-making activities or other trading activities may be a
statutory underwriter and must acknowledge that it will deliver a prospectus
meeting the requirements of the Securities Act in connection with the resale of
new notes received in exchange for old notes. The letter of transmittal which
accompanies this prospectus states that by so acknowledging and by delivering a
prospectus, a participating broker-dealer will not be deemed to admit that it is
an underwriter within the meaning of the Securities Act of 1933. A participating
    
 
                                       25
<PAGE>   28
 
   
broker-dealer may use this prospectus, as it may be amended from time to time,
in connection with resales of new notes it receives in exchange for old notes in
the exchange offer. The Issuers will make this prospectus available to any
participating broker-dealer in connection with any resale of this kind for a
period of 90 days after the expiration date of the exchange offer. See "Plan of
Distribution."
    
 
   
     Based on the position taken by the SEC staff in the interpretive letters
referred to above, the Issuers believe that broker-dealers who acquired old
notes for their own accounts as a result of market-making activities or other
trading activities ("participating broker-dealers") may fulfill their prospectus
delivery requirements with respect to the new notes received upon exchange of
such old notes, other than old notes which represent an unsold allotment from
the original sale of the old notes, with a prospectus meeting the requirements
of the Securities Act, which may be the prospectus prepared for an exchange
offer so long as it contains a description of the plan of distribution with
respect to the resale of such new notes. Subject to certain provisions set forth
in the registration rights agreement and to the limitations described herein,
the Issuers have agreed that this prospectus, as it may be amended or
supplemented from time to time, may be used by a participating broker-dealer in
connection with resales of such new notes where such old notes were acquired by
such participating broker-dealer for its own account as a result of
market-making or other trading activities for a period ending 90 days after the
expiration date or, if earlier, when all such new notes have been disposed of by
such participating broker-dealer. See "Plan of Distribution." Any person,
including any participating broker-dealer, who is an "affiliate" of the Issuers
may not rely on such interpretive letters and must comply with the registration
and prospectus delivery requirements of the Securities Act in connection with
any resale transaction.
    
 
   
     In that regard, each participating broker-dealer who surrenders old notes
pursuant to the exchange offer will not be deemed to have agreed, by execution
of the letter of transmittal or delivery of any agent's message, that, upon
receipt of notice from the Issuers of the occurrence of any event or the
discovery of any fact which makes any statement contained in this prospectus
untrue in any material respect or which causes this prospectus to omit to state
a material fact necessary in order to make the statements in the prospectus, in
light of the circumstances under which they were made, not misleading or of the
occurrence of certain other events specified in the registration rights
agreement, such participating broker-dealer will suspend the sale of new notes
pursuant to this prospectus until the Issuers have amended or supplemented this
prospectus to correct such misstatement or omission and has furnished copies of
the amended or supplemented prospectus to such participating broker-dealer or
the Issuers have given notice that the sale of the new notes may be resumed, as
the case may be.
    
 
   
     Each holder of the old notes who wishes to exchange old notes for new notes
in the exchange offer will be required to represent and acknowledge, for the
holder and for each beneficial owner of such old notes, whether or not the
beneficial owner is the holder, in the letter of transmittal that:
    
 
   
     - the new notes to be acquired by the holder and each beneficial owner, if
       any, are being acquired in the ordinary course of business,
    
 
   
     - neither the holder nor any beneficial owner is an affiliate, as defined
       in Rule 405 of the Securities Act, of Issuer or any of its subsidiaries,
    
 
   
     - the holder and each beneficial owner, if any, are not participating, do
       not intend to participate and have no arrangement or understanding with
       any person to participate
    
 
                                       26
<PAGE>   29
 
   
       in any distribution of the new notes received in exchange for old notes,
       and if such holder is not a broker-dealer, that such holder is not
       engaged in, and does not intend to engage in, a distribution of new
       notes.
    
 
   
WITHDRAWAL OF TENDERS
    
 
   
     Except as otherwise provided in this prospectus, tenders of old notes may
be withdrawn at any time prior to 5:00 p.m., New York City time, on the
expiration date of the exchange offer. Withdrawals of tenders of old notes may
not be rescinded.
    
 
   
     To withdraw a tender of old notes in the exchange offer, a letter or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth below prior to 5:00 p.m., New York City time, on
the expiration date. Any notice of withdrawal must:
    
 
   
     - specify the name of the person having deposited the old notes to be
       withdrawn,
    
 
   
     - identify the old notes to be withdrawn including the certificate
       number(s), the name of the registered holder and the principal amount of
       such old notes or, in the case of old notes transferred by book-entry
       transfer, the name and number of the account at the book-entry transfer
       facility to be credited and otherwise comply with the procedures of the
       transfer agent,
    
 
   
     - be signed by the holder in the same manner as the original signature on
       the letter of transmittal by which the old notes were tendered and
       guaranteed by an eligible institution, unless the old notes are tendered
       for the account of an eligible institution.
    
 
   
     - specify the name in which any such old notes are to be registered, if
       different from that of the person who deposited the notes.
    
 
   
     If certificates for old notes have been delivered or otherwise identified
to the exchange agent, then, before the release of the certificates the
withdrawing holder must also submit the serial numbers of the particular
certificates to be withdrawn and a signed notice of withdrawal with signatures
guaranteed by an eligible guarantor institution unless the holder is an eligible
guarantor institution.
    
 
   
     All questions as to the validity, form and eligibility, including time of
receipt, of such notices will be determined by the Issuers in their reasonable
discretion, whose determination shall be final and binding on all parties. Any
old notes so withdrawn will be deemed not to have been validly tendered for
purposes of the exchange offer, and no new notes will be issued unless the old
notes so withdrawn are validly retendered. Any old notes which have been
tendered but which are not accepted for exchange will be returned to the holder
of the notes without cost to the holder as soon as practicable after withdrawal,
rejection of tender or termination of the exchange offer. Properly withdrawn old
notes may be retendered by following one of the procedures described above under
"-- Procedures for Tendering" at any time before the expiration date.
    
 
INTEREST ON NEW NOTES
 
   
     Each new note will accrue interest from:
    
 
   
     - the most recent interest payment date on the old notes surrendered in
       exchange for such new notes, or
    
 
   
     - July 9, 1998, if no interest has been paid or provided for on such old
       notes.
    
 
                                       27
<PAGE>   30
 
   
     As a result, holders of old notes that are accepted for exchange will not
receive accrued and unpaid interest on such old notes for any period from and
after the most recent interest payment date on such old notes or, if no interest
has been paid or provided for on such old notes from and after July 9, 1998, and
such holders will be deemed to have waived the right to receive any interest on
such old notes.
    
 
   
CONDITIONS
    
 
   
     The Issuers shall not be required to accept for exchange, or exchange new
notes for, any old notes and may terminate the exchange offer as provided in
this prospectus, whether or not any old notes have been accepted, or may waive
any condition to or amend the exchange offer, if any of the following conditions
have occurred or exist or have not been satisfied:
    
 
   
     - any action or proceeding is instituted or threatened in any court or by
       or before any governmental agency with respect to the exchange offer
       which, in the reasonable judgment of the Issuers, would be expected to
       impair the ability of the Issuers to proceed with the exchange offer;
    
 
   
     - any change, or any development involving a prospective change, in the
       business or financial affairs of the Issuers or any of their subsidiaries
       has occurred which, in the reasonable judgment of the Issuers, might
       materially impair the ability of the Issuers to proceed with the exchange
       offer;
    
 
   
     - any law, statute, rule or regulation is proposed, adopted or enacted,
       which in the reasonable judgment of the Issuers, would be expected to
       impair the ability of the Issuers to proceed with the exchange offer;
    
 
   
     - there shall occur a change in the current interpretation by the SEC staff
       which permits the new notes issued pursuant to the exchange offer in
       exchange for old notes to be offered for resale, resold and otherwise
       transferred by holders thereof (other than broker-dealers and any such
       holder which is an affiliate of the Issuers) without compliance with the
       registration and prospectus delivery provisions of the Securities Act of
       1933 provided that such new notes are acquired in the ordinary course of
       such holders' business and such holders have no arrangement or
       understanding with any person to participate in the distribution of such
       new notes;
    
 
   
     - trading on the New York Stock Exchange or generally in the United States
       over-the-counter market shall have been suspended by order of the SEC or
       any other governmental authority which, in the Issuers' judgment, would
       reasonably be expected to impair the ability of the Issuers to proceed
       with the exchange offer; or
    
 
   
     - a stop order shall have been issued by the SEC or any state securities
       authority suspending the effectiveness of the registration statement of
       which this prospectus is a part or proceedings shall have been initiated
       or, to the knowledge of the Issuers, threatened for that purpose, or any
       governmental approval has not been obtained, which approval Issuers
       shall, in their reasonable discretion, deem necessary for the
       consummation of the exchange offer as contemplated hereby.
    
 
   
     If the Issuers determine in their reasonable discretion that any of the
foregoing events or conditions has occurred or exists or has not been satisfied,
the Issuers may, subject to applicable law, terminate the exchange offer,
whether or not any old notes have theretofore been accepted for exchange, or may
waive any such condition or otherwise amend the terms of the exchange offer in
any respect. If such waiver or amendment constitutes a
    
 
                                       28
<PAGE>   31
 
   
material change to the exchange offer, the Issuers will promptly disclose such
waiver by means of a prospectus supplement that will be distributed to the
registered holders of the old notes and the Issuers will extend the exchange
offer to the extent required by Rule 14e-1 under the Exchange Act.

FEES AND EXPENSES
 
   
     The Issuers have not retained any dealer-manager in connection with the
exchange offer and will not make any payments to brokers, dealers or others
soliciting acceptances of the exchange offer. The Issuers, however, will pay the
exchange agent reasonable and customary fees for its services and will reimburse
it for its reasonable out-of-pocket expenses in connection with providing such
services. The Issuers will also pay brokerage houses and other custodians,
nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them
in forwarding copies of this prospectus and related documents to the beneficial
owners of old notes, and in handling or tendering for their customers.
    
 
   
     Holders who tender their old notes for exchange will not be obligated to
pay any transfer taxes in connection therewith. If, however, new notes are to be
delivered to, or are to be issued in the name of, any person other than the
registered holder of the old notes tendered, or if a transfer tax is imposed for
any reason other than the exchange of old notes in connection with the exchange
offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the letter of transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
   
     The following Unaudited Pro Forma Consolidated Financial Information of the
Company for the year ended December 31, 1998 has been prepared to reflect (1)
the July 2, 1998 offer and sale of the old notes and (2) the consummation of the
Transaction as if it had occurred on January 1, 1998 using the purchase method
of accounting. The Unaudited Pro Forma Consolidated Financial Information does
not purport to be indicative of the operating results of the Company that would
have actually been obtained if the offering of the old notes and the Transaction
had been consummated as of and for the dates and periods presented or that may
be obtained in the future. The pro forma adjustments as described in the notes
to Unaudited Pro Forma Consolidated Financial Information are based on available
information and upon certain assumptions that management believes are
reasonable. The Unaudited Pro Forma Consolidated Financial Information should be
read in conjunction with the audited financial statements and the related notes
that appear later in this prospectus.

        NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
     The Transaction was accounted for under the purchase method of accounting.
The unaudited pro forma consolidated results of operations were determined based
on the fair value of the assets acquired and liabilities assumed and associated
amortization of goodwill and other acquired intangibles. Prior to July 9, 1998,
certain costs and expenses were allocated to the Company from Generac
Corporation. Management believes that the allocation of these costs and expenses
approximate the equivalent costs expected to be incurred on a stand alone basis.
 
     (a) Reflects the effect on cost of sales of the recognition of a
         capital lease obligation as part of the Transaction arising from
         certain equipment leases:
 
<TABLE>
<S>                                                           <C>
Actual lease expense incurred...............................  $(336)
Amortization of assets under capital lease obligations......    174

                                                              =====
</TABLE>
 
   
     (b) Reflects the amortization of goodwill of $213,738 over a 40 year period
         and the non-compete agreement of $100 and trademarks and patents of
         $100 over a 10 year period. Goodwill was calculated as the purchase
         price of $306,865 (including acquisition costs of $1,385) less the fair
         value of net assets acquired and liabilities assumed of $81,469 and
         less the excess of purchase price over book value of net assets
         acquired from entities partially under common control of $11,658. Other
         intangible assets are comprised of patents, trademarks and a non-
         compete agreement with Generac Corporation which have a remaining life
         and/or contractual term of approximately 10 years.
    
 
     (c) Interest expense reflects the following:

Senior Subordinated Notes at 11.25%.........................    6,462
Interest on capitalized leases..............................       98

                                                              $10,314

</TABLE>
 
Borrowings under the Senior Secured Credit Facility bear interest at the
Eurodollar rate, plus an applicable percentage, as defined. For the purposes of
the pro forma interest expense adjustment, the Eurodollar rate is estimated to
be 5.76% for the period January 1 through July 9, 1998. The rate approximates
the average Eurodollar rate during the period. A  1/8% variance in Eurodollar
rates for the Senior Secured Credit Facility would change assumed interest
expense by approximately $106. A commitment fee of .5% per annum is charged on
the unused portion of the Senior Secured Credit Facility.
 
     (d) Reflects the elimination of historical interest expense allocated
         from Generac Corporation.
 
     (e) The deferred financing costs are amortized using the effective interest
         rate and straight line methods over the term of the associated debt as
         follows:

     (f) Reflects adjustment for income tax expense to provide taxes at a pro
         forma effective tax rate of 35% for the respective period.
         Historically, the Company's taxable income was included in Generac
         Corporation's taxable income. Generac Corporation and its stockholders
         elected to be treated as an S Corporation for federal and certain state
         income tax purposes. Accordingly, no provision for income taxes is
         included in the historical financial statements prior to July 9, 1998.

           NOTES TO SELECTED HISTORICAL AND PRO FORMA FINANCIAL DATA
 
(a) Beginning in 1997, the Company operated as a business unit of Generac
    Corporation with separate financial reporting. During 1995, a dedicated
    manufacturing facility was completed to accommodate the portable products
    business. In connection with its move to this new facility, the Company
    began to separately identify certain assets and liabilities as specific to
    the portable products business which enabled the preparation of carve out
    financial statements as of and for the year ended December 31, 1996, albeit
    on a basis that includes certain estimates and allocations that, in the
    opinion of management, are considered to be reasonable. Prior to 1996, all
    financial information of the Company was commingled with that of Generac
    Corporation and, therefore, the Company's summary data as of and for the
    years ended December 31, 1995 and 1994 is limited and certain historical
    financial data is not available.
 
(b) Historically, the Company's taxable income was included in Generac
    Corporation's taxable income. Generac Corporation and its stockholders
    elected to be treated as an S Corporation for federal and certain state
    income tax purposes. Accordingly, no provision for income taxes is included
    in the Predecessor financial statements. The Company is subject to state and
    federal income taxes after July 9, 1998.
 
   
(c) Direct expenses are those expenses that are directly related to the
    revenue-producing activities of the Predecessor.
    
 
(d) Divisional assets include property, plant and equipment, cash, accounts
    receivable and inventories.
 
(e) Stockholders' equity represents business unit investment for all Predecessor
    periods shown and represents common stock, paid-in-capital, retained
    earnings, accumulated other comprehensive income and excess of purchase
    price over book value of net assets acquired from entities partially under
    common control for periods subsequent to the Transaction.
 
(f)  EBITDA represents earnings before interest, taxes, depreciation and
     amortization. EBITDA is a widely recognized financial indicator of a
     company's ability to service or incur debt. EBITDA is not a measure of
     operating performance computed in accordance with generally accepted
     accounting principles and should not be considered as a substitute for
     operating performance computed in accordance with generally accepted
     accounting principles and should not be considered as a substitute for
     operating income, net income, cash flows from operations, or other
     statement of operations or cash flow data prepared in conformity with
     generally accepted accounting principles, or as a measure of profitability
     or liquidity. In addition, EBITDA may not be comparable to similarly titled
     measures of other companies. EBITDA may not be indicative of the historical
     operating results of the Company or the Predecessor, nor is it meant to be
     predictive of future results of operations or cash flows. See also the
     statement of cash flows contained within the historical financial
     statements included elsewhere in this document.
 
(g) In computing the ratio of earnings to fixed charges, "earnings" represents
    income (loss) before income taxes plus fixed charges. "Fixed charges"
    consists of interest, amortization of debt issuance costs and a portion of
    rent, which is representative of the interest factor (approximately
    one-third of rent expense).

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   
     The following discussion and analysis of financial condition and results of
operations should be read in conjunction with the financial statements of the
Company, and the notes thereto, and the other financial information appearing
elsewhere in this prospectus. The following discussion includes forward-looking
statements that involve certain risks and uncertainties. See "Risk Factors."
References to the "Company" means Generac Portable Products, Inc. and its
subsidiaries, on a consolidated basis and, as the context requires, the
Company's predecessor. The "Predecessor" refers to the Portable Products
Division of Generac Corporation.
    
 
GENERAL
 
     The Company has experienced strong growth, with net sales, operating income
and EBITDA increasing at compounded annual growth rates of 50%, 81% and 88%,
respectively, from 1996 through 1998 (pro forma). The Company's growth has been
driven by product innovation, cost competitiveness, and proactive category
management in the Company's main product lines of portable generators and
pressure washers. The most important factors influencing demand for the
Company's products are increased awareness of consumer utility, favorable
demographic trends, broadened channels of distribution, and improved price
performance. The expected continuing growth of the home center and warehouse
club retail distribution channel should provide the Company with an opportunity
to increase its market share. Moreover, the Company has long-standing core
relationships with those retailers best positioned to take advantage of this
channel's rapid growth.
 
   
     The table below sets forth the Company's results of operations for the
periods indicated (dollars in millions). Included in the table is a presentation
of EBITDA, which represents earnings before interest, taxes, depreciation and
amortization. EBITDA is a widely recognized financial indicator of a company's
ability to service or incur debt. EBITDA is not a measure of operating
performance computed in accordance with generally accepted accounting principles
and should not be considered as a substitute for operating performance computed
in accordance with generally accepted accounting principles and should not be
considered as a substitute for operating income, net income, cash flows from
operations, or other statement of operations or cash flow data prepared in
conformity with generally accepted accounting principles, or as a measure of
profitability or liquidity. In addition, EBITDA may not be comparable to
similarly titled measures of other companies. EBITDA may not be indicative of
the historical operating results of the Company or the Predecessor, nor it is
meant to be predictive of future results of operations or cash flows.

RESULTS OF OPERATIONS
 
YEAR ENDED DECEMBER 31, 1998 (PRO FORMA) COMPARED TO
YEAR ENDED DECEMBER 31, 1997 (PREDECESSOR BASIS)
 
     NET SALES.  Net sales increased $98.4 million, or 55.3%, to $276.4 million
for 1998 pro forma from $178.0 million for 1997.
 
     Domestic sales increased $91.4 million, or 55.7%, to $255.4 million for
1998 pro forma from $164.0 million for 1997. This increase was primarily due to
strong overall consumer demand for generator and pressure washer product
categories throughout 1998. The broad sales increase was further reflective of
the store growth for existing customers, expanded pressure washer product
offerings to Home Depot, and strong overall generator sales resulting from
winter and summer storm activity.
 
     International sales increased $7.0 million, or 50.0%, to $21.0 million for
1998 pro forma from $14.0 million for 1997. This increase was primarily due to
increased penetration into European home center accounts.
 
                                       37
<PAGE>   40
 
     GROSS PROFIT.  Gross profit increased $26.9 million, or 57.4%, to $73.8
million for 1998 pro forma from $46.9 million for 1997. This increase was
primarily due to increased sales volume as described above and improved gross
margins. Gross profit margin increased to 26.7% in 1998 pro forma from 26.3% in
1997 as a result of the improved mix of higher margin generator sales versus
lower margin pressure washer sales and improved gross margins for International
sales.
 
   
     OPERATING EXPENSES.  Operating expenses increased $18.3 million, or 70.7%,
to $44.2 million for 1998 pro forma from $25.9 million for 1997. This increase
was primarily a result of increased selling and distribution expenses related to
the shift of domestic sales distribution into national home center markets, and
increased sales distribution costs into German home centers. Home centers
typically command higher volume, promotional and other sales incentives. In
addition, 1998 pro forma operating expenses include $5.3 million (1.9% as a
percentage of sales) in amortization of goodwill and other intangible assets
recorded in connection with the Transaction. As a percentage of sales, operating
expenses increased to 16.0% in 1998 pro forma from 14.6% in 1997.
    
 
   
     NET INCOME.  Net income decreased $12.9 million, or 69.0%, to $5.8 million
for 1998 pro forma from $18.7 million for 1997. This decrease in net income was
primarily due to increases in certain expenses resulting from effects of the
Transaction including interest expense; amortization of goodwill, deferred
financing costs and other intangible assets; and provision for income taxes.
These expenses (a $17.8 million increase in interest expense, a $6.2 million
increase in intangible asset and deferred financing cost amortization and a $3.1
million increase in income tax expense) decreased 1998 pro forma net income by
an additional $27.1 million (9.8% as a percentage of sales) as compared to 1997.
As a percentage of sales, net income decreased to 2.1% in 1998 pro forma from
10.5% in 1997.
    
 
     EBITDA.  EBITDA increased $14.7 million, or 65.9%, to $37.0 million in 1998
pro forma from $22.3 million for 1997. This increase was primarily due to
increased sales volume and improved gross margins as described above. As a
percentage of sales, EBITDA increased to 13.4% in 1998 pro forma from 12.5% in
1997.
 
JULY 10, 1998 THROUGH DECEMBER 31, 1998 (NEW BASIS) COMPARED TO
SIX MONTHS ENDED DECEMBER 31, 1997 (PRO FORMA)
 
     NET SALES.  Net sales increased $57.7 million, or 72.9%, to $136.9 million
for the period July 10, 1998 through December 31, 1998 from $79.2 million for
the pro forma six months ended December 31, 1997.
 
   
     Domestic sales increased $54.0 million, or 74.2%, to $126.8 million for the
period July 10, 1998 through December 31, 1998 from $72.8 million for the pro
forma six months ended December 31, 1997. This increase was primarily due to
strong demand for generator products sold through existing customers resulting
from summer storm activity and increased consumer awareness of the availability,
utility and economic feasibility of the product.
    
 
     International sales increased $3.7 million, or 57.8%, to $10.1 million for
the period July 10, 1998 through December 31, 1998 from $6.4 million for the pro
forma six months ended December 31, 1997. This increase was primarily due to
increased penetration into European home center accounts.
 
     GROSS PROFIT.  Gross profit increased $16.0 million, or 70.8%, to $38.6
million for the period July 10, 1998 through December 31, 1998 from $22.6
million for the pro forma six months ended December 31, 1997. This increase was
primarily due to increased sales
 
                                       38

volume as described above. Gross profit margin decreased slightly to 28.2% for
the period July 10, 1998 through December 31, 1998 from 28.5% for the pro forma
six months ended December 31, 1997 as a result of reduced gross margins on
international sales due to heavy promotional pricing into German home centers.
 
     OPERATING EXPENSES.  Operating expenses increased $6.5 million, or 41.1%,
to $22.3 million for the period July 10, 1998 through December 31, 1998 from
$15.8 million for the pro forma six months ended December 31, 1997. This
increase was attributable to increased sales volume as described above. As a
percent of sales, operating expenses decreased to 16.3% for the period July 10,
1998 through December 31, 1998 from 19.9% for the pro forma six months ended
December 31, 1997 due to the leveraging of fixed operating expenses, including
goodwill amortization.
 
     NET INCOME.  Net income increased $6.6 million for the period July 10, 1998
through December 31, 1998 to $4.2 million from a $2.4 million net loss for the
pro forma six months ended December 31, 1997. This increase was primarily due to
the availability of operating earnings from the increased sales volume to cover
certain fixed charges including interest expense; amortization of goodwill,
deferred financing costs, and other intangibles; and other operating expenses.
As a percentage of sales, net income increased to 3.1% for the period July 10,
1998 through December 31, 1998 from a net loss of 3.0% for the pro forma six
months ended December 31, 1997.
 
   
     EBITDA.  EBITDA increased $9.7 million or 94.2% to $20.0 million for the
period July 10, 1998 through December 31, 1998 from $10.3 million for the pro
forma six months ended December 31, 1997. This increase was due to the increased
sales volume and improved coverage of fixed operating expenses as described
above. As a percentage of sales, EBITDA increased to 14.6% for the period July
10, 1998 through December 31, 1998 from 13.0% for the pro forma six months ended
December 31, 1997.

     NET SALES.  Net sales increased $57.7 million, or 72.9%, to $136.9 million
for the period July 10, 1998 through December 31, 1998 from $79.2 million for
the six months ended December 31, 1997.
    
 
   
     Domestic sales increased $54.0 million, or 74.2%, to $126.8 million for the
period July 10, 1998 through December 31, 1998 from $72.8 million for the six
months ended December 31, 1997. This increase was primarily due to strong demand
for generator products sold through existing customers resulting from summer
storm activity and increased consumer awareness of the availability, utility and
economic feasibility of the product.
    
 
   
     International sales increased $3.7 million, or 57.8%, to $10.1 million for
the period July 10, 1998 through December 31, 1998 from $6.4 million for the six
months ended December 31, 1997. This increase was primarily due to increased
penetration into European home center accounts.
    
 
   
     GROSS PROFIT.  Gross profit increased $16.1 million, or 71.6%, to $38.6
million for the period July 10, 1998 through December 31, 1998 from $22.5
million for the six months ended December 31, 1997. This increase was primarily
due to increased sales volume as described above. Gross profit margin decreased
slightly to 28.2% for the period July 10, 1998 through December 31, 1998 from
28.4% for the six months ended December 31,

     OPERATING EXPENSES.  Operating expenses increased $9.2 million, or 70.2%,
to $22.3 million for the period July 10, 1998 through December 31, 1998 from
$13.1 million for the six months ended December 31, 1997. This increase was
attributable to increased sales volume as described above. In addition, during
the period July 10, 1998 through December 31, 1998, the Company recognized $2.5
million in intangible asset amortization, resulting from the effects of the
Transaction. As a percent of sales, operating expenses decreased slightly to
16.3% for the period July 10, 1998 through December 31, 1998 from 16.5% for the
six months ended December 31, 1997.
    
 
   
     NET INCOME.  Net income decreased $4.1 million for the period July 10, 1998
through December 31, 1998 to $4.2 million from $8.3 million for the six months
ended December 31, 1997. This decrease in net income was primarily due to
increases in certain expenses resulting from the effects of the Transaction
including an increase in interest expense of $8.6 million and intangible asset
and deferred financing cost amortization totaling $2.9 million. The decrease was
partially offset by an increase in operating income, net of intangible asset
amortization, of $4.3 million, resulting primarily from the increase in sales
volume and improved coverage of fixed operating expenses as described above. As
a percentage of sales, net income decreased to 3.1% for the period July 10, 1998
through December 31, 1998 from 10.5% for the six months ended December 31, 1997.
    
 
   
     EBITDA.  EBITDA increased $9.9 million or 98.0% to $20.0 million for the
period July 10, 1998 through December 31, 1998 from $10.1 million for the six
months ended December 31, 1997. This increase was due to the increased sales
volume and improved coverage of fixed operating expenses as described above. As
a percentage of sales, EBITDA increased to 14.6% for the period July 10, 1998
through December 31, 1998 from 12.8% for the six months ended December 31, 1997.
    
 
JANUARY 1, 1998 THROUGH JULY 9, 1998 (PREDECESSOR BASIS) COMPARED TO
SIX MONTHS ENDED JUNE 30, 1997 (PREDECESSOR BASIS)
 
     NET SALES.  Net sales increased $40.8 million, or 41.3%, to $139.6 million
for the period January 1, 1998 through July 9, 1998 from $98.8 million for the
six months ended June 30, 1997.
 
     Domestic sales increased $37.4 million, or 41.0%, to $128.6 million for the
period January 1, 1998 through July 9, 1998, from $91.2 million for the six
months ended June 30, 1997. This increase was primarily due to product
placements into new home center accounts, strong sales of generators to
customers located in the northeastern United States and Canada following the
winter 1998 ice storm and subsequent prolonged power outages, and expansion of
pressure washer offerings to Home Depot.
 
     International sales increased $3.4 million, or 44.7%, to $11.0 million for
the period January 1, 1998 through July 9, 1998, from $7.6 million for the six
months ended June 30, 1997. This increase was primarily due to increased
penetration into German home center accounts.
 
     GROSS PROFIT.  Gross profit increased $10.6 million, or 43.4%, to $35.0
million for the period January 1, 1998 through July 9, 1998, from $24.4 million
for the six months ended June 30, 1997. This increase was primarily due to
increased sales volume as described above and improved gross margins. Gross
profit margin increased to 25.1% for the period January 1, 1998 through July 9,
1998, from 24.7% for the six months ended June 30, 1997,
 
                                       40

as a result of the improved mix of higher margin generator sales versus lower
margin pressure washer sales.
 
     OPERATING EXPENSES.  Operating expenses increased $6.2 million, or 48.4%,
to $19.0 million for the period January 1, 1998 through July 9, 1998, from $12.8
million for the six months ended June 30, 1997. This increase was primarily a
result of increased selling and distribution expenses related to the shift of
sales distribution into national home center markets. As a percentage of sales,
operating expenses increased to 13.6% for the period January 1, 1998 through
July 9, 1998, from 13.0% for the six months ended June 30, 1997.
 
     NET INCOME.  Net income increased $4.1 million, or 39.4%, to $14.5 million
for the period January 1, 1998 through July 9, 1998, from $10.4 million for the
six months ended June 30, 1997. This increase was primarily due to increased
sales volume and improved gross margins, offset by increased operating expenses
as described above. As a percentage of sales, net income decreased to 10.4% for
the period January 1, 1998 through July 9, 1998, from 10.5% for the six months
ended June 30, 1997.
 
     EBITDA.  EBITDA increased $4.5 million, or 36.9%, to $16.7 million for the
period January 1, 1998 through July 9, 1998, from $12.2 million for the six
months ended June 30, 1997. This increase was primarily due to increased sales
volume and improved gross margins, offset by increased operating expenses as
described above. As a percentage of sales, EBITDA decreased to 12.0% for the
period January 1, 1998 through July 9, 1998, from 12.3% for the six months ended
June 30, 1997.
 
YEAR ENDED DECEMBER 31, 1997 (PREDECESSOR BASIS) COMPARED TO THE
YEAR ENDED DECEMBER 31, 1996 (PREDECESSOR BASIS)
 
     NET SALES.  Net sales increased $55.4 million, or 45.2%, to $178.0 million
for 1997 from $122.6 million for 1996.
 
     Domestic sales increased $53.9 million, or 49.0%, to $164.0 million for
1997 from $110.1 million for 1996. This increase was primarily due to increased
sales volume of overhead valve industrial engine driven generators to Home
Depot, improved pressure washer sales to Sears and expansion of product
offerings into other home center accounts.
 
     International sales increased $1.5 million, or 12.0%, to $14.0 million for
1997 from $12.5 million for 1996. This increase was primarily due to increased
penetration into European home center accounts.
 
     GROSS PROFIT.  Gross profit increased $19.6 million, or 71.8%, to $46.9
million for 1997 from $27.3 million for 1996. This increase was primarily due to
increased sales volume as described above and improved gross margins. Gross
profit margin increased to 26.3% in 1997 from 22.3% in 1996 as a result of the
migration into higher margin portable generator products, improved mix of sales
distribution, continued product cost reductions for both generator and pressure
washer product lines, and overall product cost improvements due to
diversification of worldwide supply arrangements.
 
     OPERATING EXPENSES.  Operating expenses increased $7.6 million, or 41.5%,
to $25.9 million for 1997 from $18.3 million for 1996. This increase was
primarily a result of increased selling and distribution expenses related to the
shift of sales distribution into national home center markets and incremental
warranty costs of $2.8 million related to the launch of new pressure washer
products. As a percentage of sales, operating expenses decreased to 14.6% in
1997 from 14.9% in 1996.

     NET INCOME.  Net income increased $11.9 million, or 175.0%, to $18.7
million for 1997 from $6.8 million for 1996. This increase was primarily due to
increased sales volume and improved gross margins as described above. As a
percentage of sales, net income increased to 10.5% in 1997 from 5.5% in 1996.
 
     EBITDA.  EBITDA increased $11.8 million, or 112.4%, to $22.3 million in
1997 from $10.5 million in 1996. This increase was primarily due to increased
sales volume and improved gross margins as described above. As a percentage of
sales, EBITDA increased to 12.5% in 1997 from 8.6% in 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     Following the Transaction, the Company's principal sources of liquidity are
cash flow generated from operations and borrowings under the $30 million
revolving credit portion of the credit facility. See "Description of the Senior
Secured Credit Facility" later in this prospectus. The Company's principal uses
of liquidity are to meet debt service requirements, finance the Company's
capital expenditures and provide working capital. The Company expects that the
ongoing uses of liquidity will be adequately funded by the principal sources of
liquidity throughout the upcoming year and into the foreseeable future.
    
 
   
     The Company has incurred substantial indebtedness in connection with the
Transaction. Following the Transaction, the Company had approximately $209.2
million of combined indebtedness outstanding. The Company's ability to make
scheduled payments of principal of, or to pay the interest on its indebtedness,
or to fund planned capital expenditures, will depend upon its future
performance, which in turn, is subject to general economic, financial,
competitive and other factors that are beyond its control. Based upon the
current level of operations and anticipated growth, the Company believes that
future cash flow from operations, together with available borrowings under the
credit facility, will be adequate to meet the Company's anticipated requirements
for capital expenditures, working capital, interest payments and scheduled
principal payments. There can be no assurance, however, that the Company's
business will continue to generate sufficient cash flow from operations in the
future to service its debt and make necessary capital expenditures after
satisfying certain liabilities arising in the ordinary course of business. If
unable to generate sufficient cash flow, the Company may be required to delay
necessary capital expenditures, refinance all or a portion of its existing debt,
including the notes, to sell assets or to obtain additional financing. There can
be no assurance that any such refinancing would be available or that any such
sales of assets or additional financing could be obtained. See "Risk
Factors -- We Have Substantial Existing Debt Which Could Affect Us Adversely."
    
 
   
     The credit facility and the indenture governing the notes contain a number
of covenants that, among other things, restrict the ability of the Company to
dispose of assets, repay other indebtedness, incur additional indebtedness, pay
dividends, prepay subordinated indebtedness (including, in the case of the
credit facility, the notes), incur liens, make capital expenditures and make
certain investments or acquisitions, engage in mergers or consolidations, engage
in certain transactions with affiliates and otherwise restrict the activities of
the Company. In addition, under the credit facility, Generac Portable Products,
LLC will be required to satisfy specified financial ratios and tests, including
a minimum level of earnings before interest, income taxes, depreciation and
amortization. Management does not believe that these restrictions will have a
material effect on the Company's liquidity and capital resources.

     Based upon the Company's outstanding debt at December 31, 1998, the Company
anticipates incurring interest expense (including deferred financing cost
amortization) in subsequent years as follows (dollars in millions):

</TABLE>
    
 
     Prior to the Transaction, the Company historically met its working capital
needs and capital expenditure requirements through a combination of operating
cash flow and availability under a revolving credit agreement maintained by, and
industrial revenue bonds supported by, Generac Corporation.
 
     Cash provided by operating activities totaled $16.2 million for the period
July 10, 1998 through December 31, 1998 and cash used for operating activities
totaled $13.6 million for the period January 1, 1998 through July 9, 1998. This
increase in cash generated from operations during the second half of 1998
resulted primarily from seasonal factors related to sales of pressure washers in
which the Company's level of receivables is typically highest during the second
quarter of the year as compared to other quarters.
 
     Cash provided by operating activities totaled $8.2 million for the year
ended December 31, 1997 as compared to $17.3 million for the year ended December
31, 1996. This decrease in cash generated from operating activities was
primarily a result of reductions in inventory during 1996 and the subsequent
build-up of inventory during 1997 to support increased sales activity.
 
     The Company's receivables are largely derived from large, well-established
retailers. Three customers accounted for approximately 74% of net sales for both
1998 and 1997, and account for 59% of total accounts receivable as of both
December 31, 1998 and 1997.
 
CAPITAL EXPENDITURES
 
     The Company's capital expenditures were $5.4 million, $1.4 million and $2.3
million in 1998, 1997, and 1996, respectively. The 1998 capital expenditures
related primarily to plant expansions at the Company's facilities, production
machinery and equipment and software. In an economic downturn, the Company
believes it will be able to adjust the amount spent on capital expenditures
without compromising the base requirements of its operations. The Company
expects to spend approximately $6.5 million in 1999 for various capital
projects, including increased capacity through plant expansion, cost improvement
and quality enhancement initiatives, and updating management information
systems. The Company spent approximately $1.9 million, $1.7 million and $2.5
million in 1998, 1997, and 1996, respectively, on research and development.
 
SEASONALITY, WORKING CAPITAL AND CYCLICALITY
 
     Sales of certain products of the Company are subject to seasonal variation.
Due to seasonal and regional weather factors, sales of pressure washers and
related working capital are typically higher during the second quarter than at
other times of the year. The
 
                                       43
<PAGE>   46
 
residential and commercial construction markets are sensitive to cyclical
changes in the economy.
 
RAW MATERIAL COSTS AND INFLATION
 
     The rate of inflation over recent years has been relatively low and has not
had a significant effect on the Company's results of operations. Approximately
44% of the Company's cost of goods sold relate to small gasoline engines which
have not been subject to material price fluctuations. The Company purchases
steel, copper, paperboard, and plastics from various suppliers. While all such
materials are available from numerous independent suppliers, commodity raw
materials are subject to price fluctuations.
 
YEAR 2000 STRATEGY
 
   
     Many currently installed computer systems and software products use two
digits rather than four to define the applicable year. For example,
date-sensitive software may recognize a date using "00" as the year 1900 rather
than the year 2000. This could result in systems failures or miscalculations
causing disruptions of the Company's operations. The Company is continuing a
process of making all necessary software changes to ensure that it does not
experience any loss of critical business functionality due to the Year 2000
issue. The Company has adopted and is implementing a three phase approach of
assessment, correction and testing. The scope of the project includes all
internal software, hardware, operating systems, non-information technology
systems, products and assessment of risk to the business from vendors and other
parties' Year 2000 issues. The Company has completed the assessment phase
relating to its internal software, hardware and other operating systems and is
currently in the correction and testing phases. The Company is completing its
assessment of the non-information technology systems and the risk to the
business from vendors and other parties. Furthermore, the Company has completed
the assessment of its products, noting that the Year 2000 will not impact its
products as the products do not contain date sensitive sub-systems. The Company
believes that this formal assessment (including prioritization by business
risk), correction (including conversions to new software), and testing of
necessary changes will minimize the business risk of Year 2000 from internal
systems.
    
 
   
     Although the Company has not yet fully completed its Year 2000 project,
management estimates that approximately 40% of the Company's information
sub-systems are currently Year 2000 ready. The balance of the Company's systems
are currently being modified or replaced, with all significant systems targeted
for Year 2000 readiness by September 1, 1999. The need for contingency plans
will be evaluated as this target date approaches. In most instances, the Company
has replaced, or is in the process of replacing, older software with new
programs and systems, rather than modifying existing systems solely to become
Year 2000 ready. Replacing these systems results in a significant upgrade in
systems and capabilities, as well as providing the ability to properly interpret
Year 2000 data. Although the timing of the system replacements is influenced by
the Year 2000, in most instances these systems would have been replaced in the
normal course of business.
    
 
     The Company is currently unable to predict the extent to which Year 2000
issues will affect vendors with which the Company does a material amount of
business, or the extent to which the Company would be vulnerable to the failure
of any of these vendors to convert their systems on a timely basis. The Company
could face a material financial risk if its customers or suppliers are unable to
complete critical Year 2000 readiness efforts in a timely manner. The Company is
continuing to work with its customers and suppliers to
 
                                       44
<PAGE>   47
 
   
evaluate their Year 2000 readiness, identify material risks, and develop
solutions so that all critical processes needed to conduct its business are Year
2000 ready. As part of the evaluation of the Year 2000 readiness of the
Company's customers and suppliers, the Company has requested that its customers
and suppliers complete a Year 2000 questionnaire which has facilitated the
Company's assessment of the Year 2000 readiness of relevant third parties.
Although the Company believes that customer and supplier representations have
been made in good faith, there is no assurance that such representations would
be legally binding. In addition, the Company's exposure to these external risks
is partially mitigated by the size and sophistication of its primary customers,
as well as by the diversity of its suppliers and geographic locations.
    
 
     The Company has spent approximately $0.9 million during 1998 to upgrade and
replace its systems to ensure Year 2000 readiness. The Company estimates it will
incur additional costs of approximately $1.8 million to upgrade and replace its
systems, the majority of which will be incurred in fiscal 1999. The Company
believes it continues to appropriately reduce the risks of not being Year 2000
ready through the identification and remediation process described above. During
1999, the Company will continue to evaluate the need for contingency planning as
it relates to the readiness for each business related software and hardware
item.
 
EURO CONVERSION
 
     On January 1, 1999, member countries of the European Monetary Union (EMU)
began a three-year transition from their national currencies to a new common
currency, the "Euro". In the first phase, the permanent rates of exchange
between the members' national currency and the Euro has been established and
monetary, capital, foreign exchange, and interbank markets will be converted to
the Euro. National currencies will continue to exist as legal tender and may
continue to be used in commercial transactions. By January 2002, Euro currency
will be issued and by July 2002, the respective national currencies will be
withdrawn. The Company has operations in member countries of the EMU and,
accordingly, has established action plans that are continuing to be implemented
to address the Euro's impact on information systems, currency exchange rate
risk, taxation, contracts, competition and pricing. Based on its current
assessment, management believes that the costs of the Euro conversion will not
have a material impact on the operations, cash flows or financial condition of
the Company.
 
FUTURE ACCOUNTING CHANGES
 
     The Financial Accounting Standards Board has issued SFAS No. 133
"Accounting for Derivative Instruments and Hedging Activities" which is
effective for periods beginning after June 15, 1999. Due to the Company's
current limited use of derivative instruments, the adoption of this statement is
not expected to have a material effect on the Company's financial condition or
results of operations.
 
RISK MANAGEMENT
 
     The Company is exposed to market risk from changes in interest rates and,
to a lesser extent, foreign exchange rates and commodities. To reduce such
risks, the Company selectively uses financial instruments. All hedging
transactions are authorized and executed pursuant to clearly defined policies
and procedures, which strictly prohibit the use of financial instruments for
trading purposes. A discussion of the Company's accounting policies for
derivative financial instruments is included in the summary of Significant
Accounting Policies in Note 2 to the Consolidated Financial Statements included
herein.
 
                                       45
<PAGE>   48
 
   
     The fair value of the Company's notes is estimated as $110 million as of
December 31, 1998 based upon the average yield of similar debt instruments as of
that date. The Company estimates that this fair value would increase by
approximately $6 million based upon an assumed 10% decrease in market interest
rates and that the fair value would decrease by approximately $6 million based
upon an assumed 10% increase in market interest rates, compared with the average
yield of approximately 11.25% on similar debt instruments on December 31, 1998.
    
 
   
     The Company uses interest rate swaps to modify the Company's exposure to
interest rate movements. Net interest payments or receipts from interest rate
swaps are recorded as adjustments to interest expense in the consolidated
statement of income on a current basis. The Company's earnings exposure related
to adverse movements in interest rates is primarily derived from outstanding
floating rate debt instruments that are indexed to Eurodollar money rates. A 10%
increase/decrease in the average cost of 7.84% at December 31, 1998 of the
Company's debt under its bank credit facility would result in an
increase/decrease in annual pre-tax interest expense of approximately $356,000
after giving effect to an outstanding interest rate swap. A 10%
increase/decrease in Eurodollar rates would not have a material effect on the
fair value of the interest rate swap as compared to its fair value at December
31, 1998.
    
 
     The Company has manufacturing, sales and distribution facilities throughout
Europe and sources raw materials from around the world. Accordingly, the Company

                                    BUSINESS
 
GENERAL
 
   
     We are a leading designer, manufacturer and marketer of engine-powered
tools for use in both industrial and residential applications. Our two principal
product lines are portable generators and pressure washers. We believe that in
1998, as measured by net sales, the Company was:
    
 
   
     - the largest U.S. manufacturer of portable generator sets, with an overall
       domestic market share of approximately 29%, and
    
 
   
     - the second largest U.S. manufacturer of consumer pressure washers, with a
       domestic market share of approximately 33%.
    
 
   
In both product categories, we offer one of the broadest lines of innovative
products across all major price points. We sell our products through multiple
channels of retail distribution, including the leading home center chains, mass
merchants and warehouse clubs as well as independent dealers. Since 1961, we
have been a major supplier of portable generators to Sears, and have been one of
two suppliers to Sears of pressure washers, both marketed under the Craftsman(R)
label. We are also a core supplier of portable generators and pressure washers,
both marketed under the Generac(R) label to Home Depot, the largest and one of
the fastest growing retail home center chains in the U.S.
    
 
   
     We have benefited from strong growth in the engine-powered tools market as
well as from favorable demographic trends. We believe that our strength in each
product category is the result of our strategic approach to engineering and
manufacturing which emphasizes delivering superior customer value through
innovation in product development and focus on product quality. In addition to
the manufacture of portable generators and pressure washers, we also manufacture
core components for those products, including alternators, pressure washer pumps
and blow-molded gas tanks. We believe that this strategic integration enables us
to enjoy significant cost advantages over competitors who source these
components from third party suppliers. In addition, we have been successful in
improving operating profitability through the strategic integration of our
manufacturing processes, the reconfiguration of production processes and the
standardization of components. We have long-standing customer relationships and
effectively utilize our nationwide service network to build and support our
customer base. These strengths have enabled us to service the increasingly
sophisticated and demanding customers in the retail channel. Over the past three
years, our net sales have grown at a compound annual rate of approximately 38%,
increasing from $104.8 million in 1995 to $276.4 million in 1998.
    
 
   
     Robert Kern founded Generac Portable Products in 1959 and, together with
our dedicated management team, has built the company into a leader in the
portable engine-powered tools industry. We have exclusive supply rights to the
Generac-Nagano family of engines for use in consumer portable generators,
pressure washers and welders.
    
 
COMPETITIVE STRENGTHS
 
   
     We attribute our market leadership to the following competitive strengths:
    
 
   
     LEADING MARKET POSITIONS.  We are a market leader in the U.S.
engine-powered tools industry, with an overall domestic market share of
approximately 29% in portable generators in 1998 (up from approximately 26% in
1997) and approximately 33% in pressure washers in 1998 (up from approximately
31% in 1997). In 1997, as measured by
    
 
                                       47
<PAGE>   50
 
   
net sales, we were the largest U.S. supplier of portable generators and the
second largest U.S. supplier of pressure washers. In addition, we are a core
supplier for many of the leading retail home centers and do-it-yourself
retailers. We believe that our broad and innovative product offerings, our
commitment to quality and our reputation for customer service have enabled it to
achieve revenue and earnings growth and our leading market positions.
    
 
   
     LEADING DESIGN AND ENGINEERING CAPABILITIES.  We attribute much of our
success to our innovative design and engineering expertise. Our portable
generators and pressure washers are highly engineered, durable, precision
manufactured products. We have capitalized on our design and engineering
capabilities by strategically integrating certain manufacturing components, such
as the Company-designed alternator and the Company-designed and manufactured
pressure washer pumps. As a manufacturer of certain strategic components, we
believe that we are better able to control product quality and therefore offer a
superior finished product. In addition, we believe our strategic integration
allows us to enjoy significant advantages, such as shorter lead times, lower
costs and inventory levels and greater manufacturing flexibility, that
differentiates us from many of our competitors who source these components from
third party suppliers. We believe such engineering and design expertise is
readily extendible to new product categories, as well.
    
 
   
     STRENGTH IN MULTIPLE DISTRIBUTION CHANNELS.  For over 35 years, our
portable generators have been sold under the Craftsman(R) label through Sears'
mall-based stores and, more recently, through Sears' growing chain of
freestanding hardware and dealer stores. Over the last five years, we have
expanded the distribution of our products marketed under the Generac(R) name to
include six of the leading home center retailers. Our products are also well
represented in other mass merchants, warehouse clubs, home centers and hardware
stores as well as through our independent dealer network. We believe that our
distribution strategy increases our market penetration, as we can sell our
products into the same geographic market under different brand names and through
different distribution channels. In addition, since 1995, we have significantly
increased our sales to Home Depot, the largest and one of the fastest growing
home center chains in North America. We believe that our strong strategic
relationships with leading do-it-yourself hardware vendors, such as Sears and
Home Depot, will facilitate continued market share gains as these chains grow
and as hardware channels of distribution continue to consolidate.
    
 
   
     LOW COST MANUFACTURING OPERATIONS AND STATE-OF-THE-ART FACILITIES.  We
believe that our low cost operations are attributable to our strategic
integration and increased levels of standardization in our manufacturing
processes resulting primarily from commonality of design. This commonality,
along with our efficient manufacturing processes, enable us to realize savings
through reduced inventory levels, greater leverage with suppliers and improved
production flexibility. In 1994, we built our current facility in Jefferson,
Wisconsin, which was expanded in 1996. This facility incorporates state-of-the-
art manufacturing technology and processes and was custom designed to
manufacture both of our major product lines. We are currently in the process of
expanding capacity in our Jefferson facility which we expect to complete in the
second quarter of 1999. We believe that we are one of the more vertically
integrated manufacturers of portable generators and pressure washers in the
U.S., and therefore are more cost-efficient and better able to respond to
customer demands than our competitors.
    
 
   
     ESTABLISHED BRAND NAME AND REPUTATION.  The Generac brand name has a 35
year heritage in the engine-powered tools industry. We established our leading
brand name
    
 
                                       48
<PAGE>   51
 
   
primarily by providing high-quality, innovative, reliable products as well as a
high level of customer service. We are a key supplier to leading home center
chains, including Sears, Home Depot, Lowe's and Costco, and have reinforced our
reputation with these chains by tailoring our product offerings and product
features to suit their desire for differentiated product lines.
    
 
   
     EXPERIENCED AND COMMITTED MANAGEMENT TEAM WITH SIGNIFICANT EQUITY
INCENTIVE. We have assembled a strong management team with over 100 years of
collective experience in the engine-powered tools industry. Our management team
has successfully demonstrated our ability to manage our rapid revenue and
earnings growth through maintenance of high quality standards, continuous
product innovation and commitment to customer service. Our senior management
team has a substantial financial interest in our continued success through their
direct investment in the company and participation in an incentive option
program.
    
 
   
     SUPERIOR CUSTOMER SERVICE AND COMMITMENT TO QUALITY.  We have developed
strong relationships with several of the leading home center chains and
do-it-yourself retailers, including Sears and Home Depot. These relationships
are supported by our program sales approach, which includes innovative sales and
marketing programs to educate end-users and increase retailers' effectiveness in
selling our full line of products. To this end, we have developed comprehensive
category management services which include merchandising and providing
informational materials, sales associate training and product support. To ensure
after-sale support, we differentiate ourselves by maintaining a competitive
independent dealer network, consisting of over 2,700 outdoor power equipment
dealers. We believe that the independent dealer network serves as a strong
incentive for home center and other retailers to allocate shelf space to our
products and minimizes customer returns. In addition, we maintain strict quality
inspection procedures throughout the manufacturing process. These procedures,
which include the testing of each unit prior to shipment, enable us to ensure
consistent quality. As evidence of our strong position with our customers and
our ability to provide reliable, high quality products, we have been selected as
a core supplier of portable generators and pressure washers to Home Depot, and
are the largest supplier of portable generators and pressure washers to Sears.
    
 
   
     For a discussion of certain negative factors pertaining to our competitive
position, please "Risk Factors -- We Have a Limited History of Independent
Operations and We Cannot Predict Whether We Will Be As Successful As An
Independent Company," "-- Our Operating Results Depend On Our Relationship With
Our Three Largest Customers," "-- We May Not Be Able To Manage Our Future
Growth," "-- We Face Significant Competition, Which Could Limit Our Growth,
Reduce Our Market Share and Harm Our Financial Performance" and "-- Because We
Depend On Two Manufacturing Facilities, Any Disruption In Their Operations Could
Affect Us Adversely.
    
 
BUSINESS STRATEGY
 
   
     The key elements of our strategy include:
    
 
   
     STRATEGIC ALLIANCES WITH STRONG, FAST-GROWING CUSTOMERS.  We believe that
our strong strategic relationships with leading do-it-yourself hardware vendors
such as Sears and Home Depot will enable us to gain market share as these chains
grow and as hardware channels of distribution continue to consolidate. For
example, Sears and Home Depot together plan to have approximately 3,800 stores
by the year 2000, up from approximately 2,300 in 1997. In addition, these
leading retailers are continuing to develop a variety of store formats to
broaden their customer reach. These dominant retailers are
    
 
                                       49
<PAGE>   52
 
   
actively expanding beyond the traditional do-it-yourself market and into the
commercial contractor markets and we intend to develop products to support these
retailers' commercial needs. The effectiveness of our customer strategy is best
illustrated by our relationship with Home Depot. In 1995, we sold three
generator stock keeping units in three of Home Depot's seven regions and no
pressure washer stock keeping units. Currently, we sell two pressure washer
stock keeping units and six generator stock keeping units in all eight of Home
Depot's regions. In addition, we will be implementing full point-of-purchase
support to Home Depot. We believe that we have the potential to add important
new do-it-yourself accounts and, upon the completion of the planned expansion of
our Jefferson facility, will have the capacity to meet expected demand.
    
 
   
     WELL DEFINED AND STRATEGICALLY MANAGED PRODUCT LINES.  Our strategy is to
develop a continuous stream of innovative products that deliver the highest
quality and best overall value in the industry. A driving force behind our
growth in both product categories and our expansion of gross margins has been
our proven ability to develop and deliver new products at entry-level price
points and to then successfully migrate end-users to more sophisticated products
with unique features that are designed around our proprietary components. This
strategy has been attractive to leading retailers, such as Home Depot, who use a
"good, better, best" merchandising strategy and who consider us a core supplier
in both product categories. By offering the broadest selection of portable
generators and pressure washers supported by comprehensive sales associate
training, field merchandising support and informative point-of-purchase signage
and packaging, we have become a preferred supplier to our key customers such as
Home Depot and Sears.
    
 
   
     AGGRESSIVE COST REDUCTIONS AND PRODUCTIVITY IMPROVEMENTS.  We believe that
we can maintain our position as a low cost, high-quality manufacturer by
continuing to take advantage of further opportunities, when appropriate, to
strategically integrate and manufacture components. Our decision to manufacture
core components, including pressure washer pumps, alternators and blow-molded
gas tanks, enables us to lower costs, better control product quality, shorten
supply lead times, maintain lower inventory levels and achieve greater overall
manufacturing flexibility. We believe that we are one of the U.S. industry's
more vertically integrated manufacturers and intend to continue to improve
operating profitability and maintain a high standard of product quality by
focusing on reducing costs and developing performance-enhancing product
features. In addition, we intend to continue to improve productivity and
profitability through focused industrial engineering efforts and the
standardization of components.
    
 
   
     PRODUCT INNOVATION AND DIVERSIFICATION INTO NEW AND RELATED PRODUCTS.  High
level engineering capabilities and efficient manufacturing operations provide us
with significant resources for continued product innovations as well as new
product development. Our product development program for the portable generator
product line includes:
    
 
   
     - computer controlled features;
    
 
   
     - manual transfer switches for home and commercial use;
    
 
   
     - a family of new home security packages;
    
 
   
     - development of higher kilowatt output units for commercial use; and
    
 
   
     - new vertical shaft units.
    
 
                                       50
<PAGE>   53
 
   
Our product development program for the pressure washer product line includes:
    
 
   
     - a new commercial line of gasoline-powered pressure washers;
    
 
   
     - development of an engine idle down system;
    
 
   
     - an expanded line of accessories; and
    
 
   
     - a pump family for products with higher pounds per square inch ratings.
    
 
   
     We also have new product categories under development. Our research and
development group is developing and field-testing various prototypes, which we
expect to introduce as new products over the next 12 to 24 months. Please see
"-- Products -- New and Related Products" for more information.
    
 
   
     INTERNATIONAL MARKET OPPORTUNITIES.  We offer our portable generators
throughout Europe and have been successful in building long-term customer
relationships with leading "big box" retailers in six markets: the U.K.,
Germany, Switzerland, Spain, Belgium and France. Management expects European
sales growth to accelerate over the next five years as we leverage our product
line breadth and brand equity to gain shelf space and placements in new and
existing European markets. Management believes that, as the major U.S.-based
do-it-yourself home center chains expand internationally, there will be a
growing need for their relationship suppliers, such as the company, to establish
a direct presence overseas. We plan to use our U.K. manufacturing base to
support our marketing efforts in Europe, thus realizing enhanced operating
leverage at that facility.
    
 
   
INDUSTRY OVERVIEW
    
 
   
     We compete primarily in the portable generator and pressure washer product
lines of the engine-powered tools industry.
    
 
PORTABLE GENERATORS.
 
   
     We estimate that the U.S. portable generator market was $492 million in
1998 and that it has grown at a 16% compounded annual growth rate from $230
million since 1993. We believe that this market will continue to grow at a 16%
compounded annual growth rate to reach approximately $900 million in 2002. In
1998, the U.S. portable generator market consisted of approximately ten
manufacturers, ranging from small regional producers to large manufacturers with
nationwide distribution capabilities. Sales of the six largest manufacturers
accounted for approximately 85% of the total market in 1997. Growth in this
market is driven by:
    
 
   
     - increased consumer awareness of utility;
    
 
   
     - the momentum of home center retailers;
    
 
   
     - improving price performance; and
    
 
   
     - favorable demographic trends.
    
 
   
     INCREASED CONSUMER AWARENESS OF UTILITY.  Historically, applications for
portable generators have included running power tools and other appliances at
residential as well as remote construction sites, and providing electrical power
in connection with the use of recreational vehicles and at camping sites. In
recent years, the demand by homeowners for alternative, or stand-by, power
sources has driven the growth in the portable generator market. We believe that
demand for stand-by power has increased in part by the trend toward utility
deregulation, which has increased the threat of power supply interruptions,
    
 
                                       51
<PAGE>   54
 
   
and by increasing requirements of homeowners for home security. Although we
believe that storms and other natural disasters heighten consumer awareness of
the benefits of auxiliary or stand-by power, power generator sales are not
highly seasonal. Our consumer research indicates that approximately 75% of total
portable generator sales are in anticipation of an emergency, and we believe
that the demand for stand-by power will continue to be a primary factor in the
growth of the overall market.
    
 
   
     BROADENING CHANNELS OF DISTRIBUTION.  Independent dealers, commercial and
industrial supply houses and lawn and garden outlets were the historical
channels of distribution for portable generators. These channels were
fragmented, and retailers assumed many costs associated with these products,
such as the costs of freight, inventory and handling and in-store product
support. These costs were passed on to consumers in higher prices. In recent
years, the emergence of home center chains and warehouse clubs has enhanced the
market and distribution infrastructure for engine powered tools, including
portable generators. These retailers have also driven their suppliers to offer
more competitively-priced products with higher perceived value, to offer
continuous product innovation, and to assist in the development of marketing and
merchandising efforts. As a result, these home center chains have been
instrumental in driving the growth of products such as portable generators.
    
 
     IMPROVING PRICE PERFORMANCE.  Improved price-performance has led to
increased demand for portable generators. Improvements in customer value can be
attributed to significant strides in the design, engineering and manufacturing
cost of overhead valve industrial engines, pressure washer pumps and, to a
lesser degree, electric motors and lawn mower-type gasoline engines. The most
significant enhancement to customer value has been the development of the OHVI
engine, a highly engineered product that established new industry standards for
the highest power-to-weight ratio, the lowest noise level and the longest
operating life. In 1998, portable generators equipped with OHVI engines
represented approximately 30% of the total portable generator market, up from
less than approximately 6% of the market in 1993. By the year 2002, we believe
that approximately 40% of the portable generators sold in the U.S. will be
powered by OHVI engines.
 
   
     FAVORABLE DEMOGRAPHIC TRENDS.  Recent industry data indicate that
approximately 60% of portable generator purchasers are between 45 and 65 years
old. According to U.S. census estimates, this segment of the population is
expected to grow by approximately 25% over the next six years. In addition, the
U.S. census projects that there will be over three million new homeowners over
the next five years.
    
 
PRESSURE WASHERS
 
   
     We estimate that the U.S. consumer pressure washer market was $300 million
in 1998 and has grown at a 43% compounded annual growth rate from $50 million
since 1993. We believe that this market will grow at a 15% compounded annual
growth rate to reach approximately $527 million in 2002. In addition, the U.S.
commercial pressure washer market was approximately $120 million in 1998. In
1998, the U.S. pressure washer market consisted of approximately ten
manufacturers, ranging from small regional producers to large manufacturers with
nationwide distribution capabilities. The market is consolidating, with sales of
the four largest manufacturers accounting for an estimated 80% of the total
    
 
                                       52
<PAGE>   55
 
   
market in 1998, which reflects the exit of a leading manufacturer of consumer
pressure washers during that year. Growth in the market is driven by:
    
 
   
     - increased awareness of consumer applications;
    
 
   
     - broadening channels of distribution; and
    
 
   
     - improved price-performance.
    
 
   
     INCREASED AWARENESS OF CONSUMER APPLICATIONS.  Pressure washers have been
used in commercial applications for over 50 years. In recent years, the consumer
pressure washer market has evolved, driven by increased awareness of the utility
and the ease of use of the products. Consumer applications include car washing,
deck cleaning, and pre-treating exterior surfaces prior to painting. Common
commercial applications include stripping paint, removing graffiti, farm and
agricultural uses, automotive uses, and factory and warehouse applications.
Consumer demand for pressure washers reflects the considerable increase in home
ownership, real estate values, boat and recreational vehicle ownership and
consumers' desire to preserve the value of, and enhance the appearance of, these
investments. Pressure washers also have a strong appeal to homeowners faced with
increasing demands on their time.
    
 
   
     BROADENING CHANNELS OF DISTRIBUTION.  In 1993, Sears was the first retailer
to offer an effectively merchandised and well-balanced assortment of pressure
washers for consumer applications, including car washing, deck cleaning and
paint surface preparation. Other leading home center chains began offering
pressure washers shortly thereafter, and contributed to the rapid development of
the consumer market. These home center chains have required their suppliers to
provide broader product lines and to continually improve quality, price and
product performance. We believe that such demands from the home center chains
will lead to further industry consolidation to the detriment of the smaller
participants.
    
 
     IMPROVING PRICE PERFORMANCE.  Improved price-performance has led to
increased consumer demand for gasoline powered pressure washers. These products
offer a significant step up in cleaning power, durability, engine life and
safety features at only a modest premium to the opening price point of a basic
electric pressure washer. The axial cam pump, introduced in 1994, significantly
lowered the manufacturing cost of a pressure washer in addition to improving
quality and overall customer satisfaction. The shift to axial cam pumps from
crank shaft pumps allowed the use of high-volume, low-cost vertical shaft
engines. This innovation has not only reduced retail prices but has also made
this product more convenient to use, adding to continued growth in the consumer
market.
 
PRODUCTS
 
   
     We primarily produce portable generators and pressure washers built around
commercially available lawn mower-type engines and the Generac-Nagano engine.
The Generac-Nagano engine, to which we have exclusive access for our portable
generators, pressure washers and welders, offers several value-added features to
home, recreational and commercial end-users. A typical lawn mower-type engine
has a 400-700 hour operating life, while the Generac-Nagano engine has a life
expectancy of up to 3,000 hours. Engines comparable to the Generac-Nagano which
are available to our competitors tend to sell at a premium relative to a
comparable proprietary Generac-Nagano engine. This has enabled us to gain market
share by offering a superior value to consumers and a differentiated product to
retailers.
    
 
                                       53

PORTABLE GENERATORS
 
   
     We believe that we manufacture and market the broadest line of portable
generator products in the industry. Our product offering ranges from
premium-priced models, incorporating advanced operating features and performance
characteristics built around our proprietary Generac-Nagano engine, to
value-priced products built around conventional commercially available lawn
mower-type engines. Our generator line includes the most basic units without
protective frames to complete units, and the simplest electrical outlet features
to full control panels with related features that are attractive to the
industrial and contractor markets. Our entire product line incorporates various
value-added features such as low oil shutdown and reduced noise levels.
    
 
   
     Our competitive position in the portable generator category is the result
of our state-of-the-art product design and engineering capabilities. Many of our
premium Generac-Nagano engine-powered generators are equipped with voltage
regulators which provide superior voltage control and surge capacity for
starting large electrical loads. The Generac-Nagano engine-powered units also
feature lighter weight for portability, compact size, reduced maintenance and
lower fuel consumption. Electric start is available on certain models and the
contractor units incorporate a unique idle control device which further reduces
noise, greatly extends engine operating life and additionally reduces fuel
consumption. Oversized fuel tanks for longer operating times are standard with
these units.
    
 
PRESSURE WASHERS
 
   
     Our engine-driven pressure washers incorporate unique value added features
such as a thermal overload device, which prevents overheating and resulting
failures, and an exclusive unloading circuit which makes starting easier. Our
electric pressure washer product line offers reduced noise levels, a long
operating life and an automatic start-stop feature that protects against damage
from overheating or running dry. Our proprietary pump, based on different
combinations of internally designed components and a low-cost aluminum pump
head, promotes greater manufacturing flexibility and a faster response to
evolving end-user needs. As with portable generators, end-users are offered a
premium Generac-Nagano engine-powered product which features lower fuel
consumption, longer life and lower noise levels, all of which we believe are of
great value to the end-user. We believe we are the only U.S. manufacturer in
this industry to have this level of integration in the manufacture of pressure
washers.
    
 
NEW AND RELATED PRODUCTS
 
   
     All of our new product initiatives are based on our core manufacturing and
marketing philosophy. Our strategy to expand our presence in related product
lines has three major components. In the power generator market, we plan to
leverage our exclusive access to the Generac-Nagano engine to introduce high
value models at competitive price points. For example, our 4000XL model, as
currently priced to the end-user, offers technically advanced consumer benefits
at half to 2/3 the retail price of a comparable Honda product. Management
anticipates that this compelling price performance ratio will significantly
increase demand in the premium-priced line relative to low-end, lower-margin
generator sets.
    
 
   
     In the pressure washer category, we introduced our first product designed
specifically for the commercial market in 1998. This commercial product has been
designed around the same Generac-Nagano engine as used in portable generators,
providing longer life for trouble-free power compared to competitive offerings.
Manage-
    
 
                                       54

ment believes that as the large home center chains focus increasingly on the
commercial contractor and home construction markets, our established position in
these channels, as well as in various catalogs directed at professionals, should
enable us to penetrate this segment rapidly. We estimate that the market for
these products was approximately $120 million in 1998.
    
 
   
     Finally, over the next 12 to 24 months, we plan to continue to
competitively position our entry level vertical shaft gasoline pressure washer
to encourage the present electric pressure washer owner to trade-up to a higher
powered gasoline unit. Our product positioning is focused on providing
significantly greater cleaning power, longer engine life and user-friendly
accessories at a modest premium to competitive electric pressure washers.
    
 
   
     Superior design and engineering capabilities and low-cost manufacturing
operations provide us with a significant resource for developing new product
categories. We have identified several new product and business opportunities in
which we can provide added value to end-users and attractive profit margins to
retailers. Our research and development group is in the latter stages of
developing and field-testing these products. Management expects to introduce the
following products over the next 12 to 24 months:
    
 
   
     - Computer controlled generators
    
 
   
     - Generator sets for the recreation market
    
 
   
     - Full line of easy-to-use home standby packages
    
 
   
     - Commercial pressure washers
    
 
   
     - Expanded line of accessories
    
 
   
     The Company incurred research and development costs of $1.9 million in
1998, $1.7 million in 1997 and $2.5 million in 1996.
    
 
DISTRIBUTION AND MARKETING
 
   
     Our three largest customers are Home Depot, Sears and Costco, which
accounted for, in the aggregate, approximately 74% of sales for the year ended
December 31, 1998. We also sell to other consumer home centers and warehouse
clubs, as well as outdoor power equipment dealers. In addition to traditional
retail distribution, we offer our products through national catalog companies
such as Northern Hydraulic, Sears Power Tool catalog and our own "special-order"
service.
    
 
   
     Since 1961, we have been a major supplier of portable generators to Sears
one of two suppliers to Sears of pressure washers since Sears first introduced
that product category in 1994. We have developed a longstanding partnership with
Sears involving the development of exclusive product offerings under the
Craftsman(R) label, high levels of in-store sales support, well-coordinated
merchandising and promotional campaigns and access to Sears' nationwide service
network. In both the portable generator and pressure washer categories, we have
collaborated with Sears to create high-impact in-store displays that provide
both an assortment of products and informative point-of-purchase materials to
help guide end-users in their purchasing decision. We also offer to Sears other
value-added, in-store services such as sales associate training and product
support. We believe that our partnership with Sears and its ability to affect
merchandise presentation at the point-of-purchase, particularly its visual
merchandising and packaging, has had a strong
    
 
                                       55
<PAGE>   58
 
   
impact on Sears' portable generator and pressure washer sales and profitability.
We continue to increase our sales through Sears' expanding hardware distribution
channels including our new local hardware stores, dealer stores and Orchard
Supply.
    
 
   
     Over the past three years, we have expanded the distribution of our
products, marketed under the Generac(R) name, to home centers and warehouse
clubs. Borrowing from our experience at Sears, we offer to our customers a total
category management approach, including value-added, in-store services such as
merchandising, informational materials, sales associate training and product
support. We believe that our ability to affect merchandise presentation at the
point-of-purchase, particularly its visual merchandising and packaging, has had
a strong impact on retailers' portable generator and pressure washer sales and
profitability. Major U.S. retail customers now include Home Depot, Lowe's,
Costco and Tru-Serve Incorporated. We are well-represented in six of the leading
home center retailers in Europe.
    
 
   
     We employ a two-tiered sales force to sell our products through mass
merchants, home centers and independent dealer channels. Product managers are
responsible for developing sales programs tailored to retailer-specific needs in
the home center and warehouse club channels. Territory sales managers are
responsible for establishing new independent dealers, training sales associates
at a store level, and managing and reducing product returns. Territory sales
managers also serve as the primary interface between our manufacturing operation
and our independent dealer network.
    
 
   
     We have assembled a comprehensive after-sales service network in North
America for generator sets and pressure washers comprised of (1) 2,700
authorized independent dealers, (2) 11 independently owned master parts
distributors and (3) a Company-owned fleet of mobile service training vehicles.
In today's retail environment, most independent dealers do not generate the
traffic to be competitive with mass merchants, home centers or warehouse clubs.
Nevertheless, we have made a strategic decision to maintain the viability of the
independent dealer network for the express purpose of providing after sales
service capability that supports our product. We have positioned ourselves not
only to respond to short-term warranty needs but to maintain service capability
throughout the life of the product as well. Many of the master part distributors
have their own sales force, which effectively broadens the availability of our
products and spare parts.
    
 
PRODUCT TECHNOLOGY AND DEVELOPMENT
 
   
     Our ability to serve both retailers and end-users is effectively driven by
the strength of our engineering and product development capabilities,
particularly in alternator and pump design. In 1959, we were the first to
exploit silicon-diode technology to completely redesign the alternator, thereby
fundamentally improving the manufacturing economics and performance
characteristics of portable generators. Similar performance improvements have
been associated with the Generac-Nagano engine, the pressure washer pump and the
computer-controlled generator. In recognition of our design and engineering
competency, Briggs & Stratton, one of the world's largest commercial engine
manufacturers, engaged us to design and set up manufacturing for its first V
Twin Vanguard engine. We were instrumental in assisting in the establishment of
the joint venture company of Dihatsu Briggs & Stratton in Japan, which is the
manufacturer of the Vanguard engine.
    
 
   
     In the pressure washer category, we have leveraged our engineering-driven
culture to turn areas of potential vulnerability into competitive strengths. For
example, to reduce our dependence on inflexible and often unpredictable overseas
suppliers of highly engineered pressure water pumps, we design and now
manufacture our own pressure washer pump.
    
 
                                       56
<PAGE>   59
 
   
This pump is based on our axial cam technology, resulting in increased
responsiveness to market demands and avoiding the costly air freight expenses
incurred in the past.
    
 
   
     Our ability to successfully commercialize technical innovations is a core
competency and is expected to continue to contribute to revenue and profit
growth. Today's retail environment demands a continuous flow of new,
value-enhanced offerings to maintain product placements and shelf space
allocations. The majority of our new product development initiatives are based
on the portable generator and pressure washer markets. However, our new product
development group is in the latter stages of developing and field-testing
products outside of these core markets that we expect to introduce over the next
12 to 24 months. See "-- Products -- New and Related Products."
    
 
INTERNATIONAL SALES AND DISTRIBUTION
 
   
     We have been successful in building long-term customer relationships with
the leading "big box" home center retailers in six European markets: the U.K.,
Germany, Switzerland, Spain, Belgium and France. To support our growing European
power generator business, local sales offices have been established in
Manchester, Cologne and Barcelona. To service our European customer base more
effectively, we design and assemble our European products in our Cheshire,
England facility. This facility imports alternators, engines and pumps and other
components and assembles portable generators to meet local product requirements
and quality assurance regulations.
    
 
   
     Our international operations have contributed approximately 8% of total net
sales for calendar year 1998. We plan to focus on international expansion as a
key part of our strategy. See "-- Business Strategy -- International Market
Opportunities."
    
 
COMPETITION
 
   
     The U.S. engine powered tools industry has experienced significant
consolidation over the last 10 to 15 years. The number of competitors in its
products categories has decreased from approximately 20 in 1985 to approximately
ten today, of which only four companies have national distribution capabilities.
Although the Company experiences substantial competition from these competitors,
the Company believes that it is a market leader in each of its core products. In
the manufacture and sale of portable generators, the Company competes primarily
with Coleman Powermate, a division of The Coleman Company, Inc. and Honda. In
the manufacture and sale of pressure washers, the Company competes primarily
with DeVilbiss Air Power Company, a subsidiary of Falcon Building Products,
Inc., and, to a lesser extent, with Alfred Karcher GmbH & Co. and Campbell
Hausfeld, a division of The Campbell Group.
    
 
MANUFACTURING
 
   
     We believe that we are one of the more vertically-integrated manufacturers
of portable generators and pressure washers in the U.S. Management believes that
sustained levels of capital investment and a commitment to manufacturing and
technological excellence are important to remain competitive from both a price
and product offering perspective.
    
 
   
     We operate a state-of-the-art manufacturing facility in Jefferson,
Wisconsin. Completed in January 1995, the original 120,000-square foot facility
was expanded by 57,500 square feet in January 1997 and 72,000 square feet in
April, 1999 to add capacity for the manufacturing of electric pressure washers
and pressure washer pumps. We are currently in the process of increasing
capacity in this facility.
    
 
                                       57
<PAGE>   60
 
   
     The Jefferson plant incorporates facilities for blow molding of plastic
tanks; robotic welding of cradles; powder coat painting of metal components;
machining; a complete rotor and stator production line with an automated
varnishing system; the latest alternator winding technology available;
high-volume assembly lines for one, which represents the latest alternator
winding technology available, to 12 kilowatt portable generators and 1300 pounds
per square inch to 3500 pounds per square inch pressure washers; and on-line
testing, packaging and warehousing facilities.
    
 
   
     We also own and operate a manufacturing facility in Cheshire, England,
which was built in 1990 and recently expanded from approximately 18,000 square
feet to approximately 45,000 square feet.
    
 
   
ENGINE SUPPLY
    
 
   
     We have used the Generac-Nagano overhead valve industrial engine in certain
of our products since 1992. Currently, approximately 32% of our sales are from
products that incorporate the Generac-Nagano engine. At the time of the
acquisition of the Portable Products Division of Generac Corporation, we entered
into an engine supply agreement with Generac Corporation. This agreement
provides that Generac Corporation will supply us with certain models of the
Generac-Nagano engine for use in our pressure washers, consumer portable
generators and welders on an exclusive basis as long as we make minimum annual
purchases of Generac-Nagano engines. This agreement also gives us the right to
increase the number of engines purchased based on our forecast requirements. The
initial term of the engine supply agreement is for a period of nine years, with
provision for three year renewals, subject to certain conditions. Please read
"Risk Factors -- Our Operating Results May Suffer If We Cannot Obtain a
Sufficient Supply of the Generac Engine or If We Lose the Exclusive Right to Use
the Generac Engine in Our Products" for a discussion of certain risks associated
with the terms of this agreement.
    
 
   
     We also purchase engines from Briggs & Stratton, Tecumseh and Honda.
    
 
   
EMPLOYEES
    
 
   
     As of December 31, 1998, we had approximately 980 employees, the majority
of whom were involved in production and distribution, with the balance engaged
in technical, administration, sales and clerical work. Of these employees, 930
were employed in the United States and 50 in the U.K. Although all of our
production employees are covered by a collective bargaining agreement, only up
to ten of our employees have been unionized. The collective bargaining agreement
expires in October 1999, which we expect to negotiate and renew when it expires.
We believe that our relationship with our employees is good.
    
 
ENVIRONMENTAL MATTERS
 
   
     Our operations are subject to federal, state and local laws and regulations
governing, among other things, emissions to air, discharge to waters, the
generation, handling, storage, transportation, treatment and disposal of waste
and other materials and health and safety matters. We believe that our business,
operations and facilities have been and are being operated in compliance in all
material respects with applicable environmental and health and safety laws and
regulations, many of which provide for substantial fines and criminal sanctions
for violations. However, the operation of manufacturing plants entails risks in
these areas, and there can be no assurance that we will not incur material costs
or liabilities in the future. In addition, potentially significant expenditures
could be required in
    
 
                                       58
<PAGE>   61
 
order to comply with evolving environmental and health and safety laws,
regulations or requirements that may be adopted or imposed in the future.
 
LEGAL PROCEEDINGS
 
   
     We are involved from time to time in litigation arising out of our business
operations. Most of such litigation involves claims for personal injury,
property damage, breach of contract and claims involving employee relations and
certain administrative proceedings. We believe such claims do not involve a risk
of material loss to the company.
    
 
PROPERTIES
 
   
     We currently own and operate an approximately 177,500 square foot
manufacturing and warehouse facility in Jefferson, Wisconsin, which was expanded
by approximately 72,000 square feet in the first quarter of 1999, and an
approximately 45,000 square foot manufacturing facility in Cheshire, England. We
believe that our manufacturing plants are generally well-maintained, in good
condition and, upon completion of the expansion, are adequate to meet our
present needs. In addition, we have sales offices in Manchester, England,
Cologne, Germany and Barcelona, Spain, and warehousing facilities in Jefferson
and Waukesha, Wisconsin, all of which are leased. We do not believe that we will
have any difficulty renewing any real property lease or finding alternative
sites.

               DESCRIPTION OF THE SENIOR SECURED CREDIT FACILITY
 
   
     Generac Portable Products, LLC has entered into a senior secured credit
facility with a group of lenders and Bankers Trust Company, as administrative
agent and arranger, providing for up to $115.0 million of loans. The credit
facility consists of (1) a $45.0 million senior secured term loan facility, (2)
a $40.0 million senior secured term loan facility, and (3) a $30.0 million
senior secured revolving credit facility. The revolving credit facility will
have a letter of credit sublimit of $5.0 million.
    
 
   
     USE OF PROCEEDS; MATURITY.  Proceeds of the term loan facilities were used
to fund, in part, Generac Portable Products, LLC's acquisition of the Portable
Products Division of Generac Corporation and pay the related fees and expenses .
Proceeds of the revolving credit facility will be used for general corporate and
working capital purposes. The $45.0 million term loan facility will mature on
December 31, 2003. The $40.0 million term loan facility will mature on June 30,
2005. The $45.0 million term loan facility provides for amortization of $2.5
million in the first year, $6.25 million in the second year, $7.5 million in the
third year, $10.0 million in the fourth year, $12.5 million in the fifth year
and $6.25 million in the sixth year. The $40.0 million term loan facility
provides for nominal annual amortization in the first five years and
amortization of $19 million in each of the sixth and seventh years. The
revolving credit facility will mature on December 31, 2003.
    
 
   
     PREPAYMENT; REDUCTION OF COMMITMENTS.  Borrowings under the credit facility
are required to be prepaid, subject to certain exceptions, from:
    
 
   
     - 100% of the net proceeds of asset sales by Generac Portable Products, LLC
       and its subsidiaries (subject to exceptions for reinvestment of certain
       asset sale proceeds and certain de minimis exceptions);
    
 
   
     - 100% of the net proceeds from certain issuances of debt obligations by
       Generac Portable Products, Inc., Generac Portable Products, LLC or their
       subsidiaries;

last day of the relevant interest period, however, the lenders' costs must be
reimbursed. Voluntary prepayments under the term loan facilities will be
allocated among those facilities on a pro rata basis. The amounts so allocated
will be applied to reduce future scheduled amortization payments on a pro rata
basis.

and the revolving credit facility are based, at the option of Generac Portable

reductions in Generac Portable Products, Inc.'s consolidated debt to EBITDA
ratio.

subordinate in right of payment to all Senior Debt of the Issuers.
    
 
   
     The Issuers will issue the notes in fully registered form only, without
coupons, in denominations of $1,000 and integral multiples of $1,000. Bankers
Trust Company will initially act as paying agent and registrar for the new
notes. The new notes may be presented for registration or transfer and exchange
at the offices of the registrar, which initially will be Bankers Trust Company's
corporate trust office. The Issuers may change any paying agent and registrar
without notice to holders of the new notes. The Issuers will pay principal (and
premium, if any) on the new notes at Bankers Trust Company's corporate office in
New York, New York. At the Issuers' option, interest may be paid at Bankers
Trust Company's corporate trust office or by check mailed to the registered
address of holders. Any old notes that remain outstanding after the completion
of the exchange offer, together with the new notes issued in connection with the
exchange offer, will be treated as a single class of securities under the
indenture.
    
 
PRINCIPAL, MATURITY AND INTEREST
 
   
     The notes will be limited in aggregate principal amount to $160.0 million,
of which $110.0 million in aggregate principal amount has been issued, and all
of which will mature on July 1, 2006. Additional notes in an aggregate amount of
up to $50.0 million may be issued from time to time, subject to the limitations
set forth under "-- Certain Covenants -- Limitation on Incurrence of Additional
Indebtedness." Interest on the new notes will accrue at the rate of 11 1/4% per
annum and will be payable semiannually in arrears in cash on each January 1 and
July 1 commencing on January 1, 1999, to the persons who are registered holders
at the close of business on the December 15 and June 15 immediately preceding
the applicable interest payment date. Interest on the new notes will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from and including the date of issuance.
    
 
   
     The new notes will not be entitled to the benefit of any mandatory sinking
fund.
    
 
REDEMPTION
 
   
     OPTIONAL REDEMPTION.  The new notes will be redeemable, at the Issuers'
option, in whole at any time or in part from time to time, on and after July 1,
2002, upon not less than 30 nor more than 60 days' notice, at the following
redemption prices (expressed as
    
 
                                       71

percentages of the principal amount thereof) if redeemed during the twelve-month
period commencing on July 1 of the year set forth below:

In addition, Generac Portable Products, LLC must pay accrued and unpaid interest
on the notes redeemed.
    
 
   
     OPTIONAL REDEMPTION UPON PUBLIC EQUITY OFFERINGS.  At any time, or from
time to time, on or prior to July 1, 2001, the Issuers may, at their option, use
the net cash proceeds of one or more Public Equity Offerings (as defined below)
to redeem up to 35% of the principal amount of the notes issued under the
indenture at a redemption price of 111.25% of the principal amount of the notes
plus accrued and unpaid interest; provided that:
    
 
   
     - at least 65% of the principal amount of the notes issued under the
       indenture remains outstanding immediately after any such redemption; and
    
 
   
     - the Issuers make such redemption not more than 120 days after the
       consummation of any such Public Equity Offering.
    
 
   
     "Public Equity Offering" means an underwritten public offering of Qualified
Capital Stock of Generac Portable Products, Inc. or Generac Portable Products,
LLC pursuant to a registration statement filed with the SEC in accordance with
the Securities Act, other than an offering pursuant to Form S-8 (or any
successor form); provided that, in the event of a Public Equity Offering by
Generac Portable Products, Inc., Generac Portable Products, Inc. contributes to
the capital of Generac Portable Products, LLC the portion of the net cash
proceeds of such Public Equity Offering necessary to pay the aggregate
redemption price (plus accrued interest) of the new notes to be redeemed.
    
 
SELECTION AND NOTICE OF REDEMPTION
 
   
     In the event that the Issuers choose to redeem less than all of the new
notes, selection of the notes for redemption will be made by the trustee either:
    
 
   
     - in compliance with the requirements of the principal national securities
       exchange, if any, on which such notes are listed, or
    
 
   
     - on a pro rata basis, by lot or by such method as the trustee shall deem
       fair and appropriate.
    
 
   
     No notes of a principal amount of $1,000 or less shall be redeemed in part.
If a partial redemption is made with the proceeds of a Public Equity Offering,
the trustee will select the new notes only on a pro rata basis or on as nearly a
pro rata basis as is practicable (subject to DTC procedures). Notice of
redemption will be mailed by first-class mail at least 30 but not more than 60
days before the redemption date to each holder of notes to be redeemed at its
registered address. If any note is to be redeemed in part only, the notice of
redemption that relates to such note shall state the portion of the principal
amount of the note to be redeemed. A new note in a principal amount equal to the
unredeemed portion of the redeemed note will be issued in the name of the holder
    
 
                                       72
<PAGE>   75
 
   
upon cancellation of the original note. On and after the redemption date,
interest will cease to accrue on notes or portions of the notes called for
redemption as long as Generac Portable Products, LLC has deposited with the
paying agent funds in satisfaction of the applicable redemption price pursuant
to the indenture.
    
 
SUBORDINATION
 
   
     The payment of all Obligations on the new notes is subordinated in right of
payment to the prior payment in full in cash or Cash Equivalents of all
Obligations on Senior Debt of the Issuers. The holders of Senior Debt will be
entitled to receive payment in full in cash of all Obligations due in respect of
Senior Debt (including interest after the commencement of any bankruptcy or
other like proceeding at the rate specified in the applicable Senior Debt
whether or not such interest is an allowed claim in any such proceeding) before
the holders of notes will be entitled to receive any payment with respect to the
notes in the event of any distribution to creditors of the Issuers:
    
 
   
     - in a liquidation or dissolution of the Issuers;
    
 
   
     - in a bankruptcy, reorganization, insolvency, receivership or similar
       proceeding relating to the Issuers or their property;
    
 
   
     - in an assignment for the benefit of creditors; or
    
 
   
     - in any marshalling of the Issuers' assets and liabilities.
    
 
   
     The Issuers also may not make any payment in respect of the new notes if:
    
 
   
     - a payment default on Designated Senior Debt occurs and is continuing; or
    
 
   
     - any other default occurs and is continuing on Designated Senior Debt that
       permits holders of the Designated Senior Debt to accelerate its maturity
       and the trustee receives a notice of such default (a "Payment Blockage
       Notice") from the representative of any Designated Senior Debt.
    
 
   
     Payments on the notes may and shall be resumed:
    
 
   
     - in the case of a payment default, upon the date on which such default is
       cured or waived; and
    
 
   
     - in case of a nonpayment default, the earlier of the date on which such
       nonpayment default is cured or waived (so long as no other event of
       default exists) or 180 days after the date on which the applicable
       Payment Blockage Notice is received, unless the maturity of any
       Designated Senior Debt has been accelerated.
    
 
   
     No new Payment Blockage Notice may be delivered unless and until 360 days
have elapsed since the effectiveness of the immediately prior Payment Blockage
Notice.
    
 
   
     No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the trustee shall be, or be made, the
basis for a subsequent Payment Blockage Notice unless such default shall have
been cured or waived for a period of not less than 90 days.
    
 
   
     The Issuers must promptly notify holders of Senior Debt if payment of the
notes is accelerated because of an Event of Default.
    
 
   
     As a result of the subordination provisions described above in the event of
a bankruptcy, liquidation or reorganization of the Issuers, holders of the notes
may recover
    
 
                                       73
<PAGE>   76
 
   
less ratably than creditors of the Issuers who are holders of Senior Debt. At
March 31, 1999, the aggregate amount of Senior Debt outstanding was
approximately $214.8 million.
    
 
   
GENERAC PORTABLE PRODUCTS, INC. GUARANTEE
    
 
   
     Generac Portable Products, Inc. will guarantee fully and unconditionally
the obligations of the Issuers under the notes and the indenture (the
"Guarantee") on a senior subordinated basis. The Guarantee will be subordinated
in right of payment to all Senior Debt of Generac Portable Products, Inc. to the
same extent that the notes are subordinated to the Senior Debt of the Issuers.
Since Generac Portable Products, Inc. is a holding company with no significant
operations, the Guarantee provides little, if any, additional credit support for
the notes, and investors should not rely on the Guarantee in evaluating an
investment in the notes. The obligations of Generac Portable Products, Inc.
under the Guarantee will be limited as necessary to prevent the Guarantee from
constituting a fraudulent conveyance or fraudulent transfer under applicable
law.
    
 
CHANGE OF CONTROL
 
   
     The indenture provides that upon the occurrence of a Change of Control,
each holder will have the right to require that the Issuers purchase all or a
portion of such holder's notes pursuant to the offer described below (the
"Change of Control Offer"), at a purchase price equal to 101% of the principal
amount of such notes plus accrued interest to the date of purchase.
    
 
   
     Within 30 days following the date upon which the Change of Control
occurred, the Issuers must send, by first class mail, a notice to each holder,
with a copy to the trustee, which notice shall govern the terms of the Change of
Control Offer. Such notice shall state, among other things, the purchase date,
which must be no earlier than 30 days nor later than 60 days from the date such
notice is mailed, other than as may be required by law (the "Change of Control
Payment Date"). Holders electing to have a note purchased pursuant to a Change
of Control Offer will be required to surrender the note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the note completed, to
the paying agent at the address specified in the notice prior to the close of
business on the third business day prior to the Change of Control Payment Date.
    
 
   
     Prior to the mailing of such notice, but in any event within 30 days
following any Change of Control, the Issuers covenant to:
    
 
   
     - repay in full and terminate all commitments under Indebtedness under the
       Credit Agreement and all other Senior Debt the terms of which require
       repayment upon a Change of Control or offer to repay in full and
       terminate all commitments under all Indebtedness under the Credit
       Agreement and all other such Senior Debt and to repay the Indebtedness
       owed to each lender which has accepted such offer; or
    
 
   
     - obtain the requisite consents under the Credit Agreement and all other
       Senior Debt to permit the repurchase of the new notes.
    
 
   
     The Issuers shall first comply with such covenant before they must
repurchase the notes pursuant to the provisions described above. The Issuers'
failure to comply with such covenant shall constitute an Event of Default
described in clause (3) and not in clause (2) under "Events of Default" below.
    
 
   
     If a Change of Control Offer is made, there can be no assurance that the
Issuers will have available funds sufficient to pay the Change of Control
purchase price for all the new notes that might be delivered by holders seeking
to accept the Change of Control Offer. In
    
 
                                       74
<PAGE>   77
 
   
the event the Issuers are required to purchase outstanding notes pursuant to a
Change of Control Offer, the Issuers expect that they would seek third-party
financing to the extent they do not have available funds to meet their purchase
obligations. However, there can be no assurance that the Issuers would be able
to obtain such financing.
    
 
   
     None of the Board of Directors of either of the Issuers or the trustee may
waive the covenant relating to a holder's right to redemption upon a Change of
Control. Restrictions in the indenture described herein on the ability of the
Issuers and their Restricted Subsidiaries to incur additional Indebtedness, to
grant liens on their property, to make Restricted Payments and to make Asset
Sales may also make more difficult or discourage a takeover of Generac Portable
Products, Inc. or the Issuers, whether favored or opposed by the management of
Generac Portable Products, Inc. or the Issuers. Consummation of any such
transaction in certain circumstances may require redemption or repurchase of the
new notes, and there can be no assurance that the Issuers or the acquiring party
will have sufficient financial resources to effect such redemption or
repurchase. Such restrictions and the restrictions on transactions with
Affiliates may, in certain circumstances, make more difficult or discourage any
leveraged buyout of the Issuers or any of their respective Subsidiaries by the
management of the Issuers. While such restrictions cover a wide variety of
arrangements which have traditionally been used to effect highly leveraged
transactions, the indenture may not afford the holders of notes protection in
all circumstances from the adverse aspects of a highly leveraged transaction,
reorganization, restructuring, merger or similar transaction.
    
 
   
     The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of notes pursuant to a Change of Control Offer. To the extent that
the provisions of any securities laws or regulations conflict with the "Change
of Control" provisions of the indenture, the Issuers shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached their obligations under the "Change of Control" provisions of the
indenture.
    
 
CERTAIN COVENANTS
 
   
     The indenture contains, among others, the following covenants:
    
 
   
     LIMITATION ON INCURRENCE OF ADDITIONAL INDEBTEDNESS.  Generac Portable
Products, LLC will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create, incur, assume, guarantee, acquire, become
liable, contingently or otherwise, with respect to, or otherwise become
responsible for payment of (collectively, "incur") any Indebtedness (other than
Permitted Indebtedness); provided, however, that if no Default or Event of
Default shall have occurred and be continuing at the time of or as a consequence
of the incurrence of any such Indebtedness, Generac Portable Products, LLC may
incur Indebtedness (including, without limitation, Acquired Indebtedness) and
Restricted Subsidiaries of Generac Portable Products, LLC may incur Acquired
Indebtedness, in each case if on the date of the incurrence of such
Indebtedness, after giving effect to the incurrence thereof, the Consolidated
Fixed Charge Coverage Ratio of Generac Portable Products, LLC is greater than
(a) 2.0 to 1.0 if the date of such incurrence is on or prior to December 31,
1999, or (b) 2.25 to 1.0 if the date of such incurrence is after December 31,
1999.

     (1) declare or pay any dividend or make any distribution (other than
         dividends or distributions payable in Qualified Capital Stock of
         Generac Portable Products, LLC) on or in respect of shares of Generac
         Portable Products, LLC's Capital Stock to holders of such Capital
         Stock,
    
 
   
     (2) purchase, redeem or otherwise acquire or retire for value any Capital
         Stock of Generac Portable Products, LLC or any warrants, rights or
         options to purchase or acquire shares of any class of such Capital
         Stock,
    
 
   
     (3) make any principal payment on, purchase, defease, redeem, prepay,
         decrease or otherwise acquire or retire for value, prior to any
         scheduled final maturity, scheduled repayment or scheduled sinking fund
         payment, any Indebtedness of Generac Portable Products, LLC that is
         subordinate or junior in right of payment to the new notes or
    
 
   
     (4) make any Investment (other than Permitted Investments) (each of the
         foregoing actions set forth in clauses (1), (2), (3) and (4) being
         referred to as a "Restricted Payment");
    
 
   
if at the time of such Restricted Payment or immediately after giving effect to
the Restricted Payment,
    
 
        (i)  a Default or an Event of Default shall have occurred and be
             continuing; or
 
   
        (ii)  Generac Portable Products, LLC is not able to incur at least $1.00
              of additional Indebtedness (other than Permitted Indebtedness) in
              compliance with the "Limitation on Incurrence of Additional
              Indebtedness" covenant; or
    
 
   
        (iii) the aggregate amount of Restricted Payments (including such
              proposed Restricted Payment) made subsequent to the Issue Date
              (the amount expended for such purposes, if other than in cash,
              being the fair market value of such property as determined in good
              faith by the Board of Directors of Generac Portable Products, LLC)
              shall exceed the sum of:
    
 
   
             (w) 50% of the cumulative Consolidated Net Income (or if cumulative

                 loss) of Generac Portable Products, LLC earned subsequent to
                 the Issue Date and on or prior to the date the Restricted

                 a single accounting period); plus
    
 
   
             (x) 100% of the aggregate net cash proceeds received by Generac
                 Portable Products, LLC from any Person (other than a Subsidiary
                 of Generac Portable Products, LLC) from the issuance and sale
                 subsequent to the Issue Date and on or prior to the Reference
                 Date of Qualified Capital Stock of Generac Portable Products,
                 LLC; plus
    
 
   
             (y) without duplication of any amounts included in clause (iii)(x)
                 above, 100% of the aggregate net cash proceeds of any equity
                 contribution received by Generac Portable Products, LLC from a
                 holder of Generac Portable Products, LLC's Capital Stock

                 Offering to the extent used to redeem the new notes in
                 compliance with the provisions set forth under
                 "Redemption-Optional Redemption Upon Public Equity Offerings");
                 plus
    
 
   
             (z) without duplication, the sum of:
    
 
             (1) the aggregate amount returned in cash on or with respect to
                 Investments (other than Permitted Investments) made subsequent
                 to the Issue Date whether through interest payments, principal
                 payments, dividends or other distributions or payments;
 
   
             (2) the net cash proceeds received by Generac Portable Products,
                 LLC or any of its Restricted Subsidiaries from the disposition
                 of all or any portion of such Investments (other than to a
                 Subsidiary of Generac Portable Products, LLC); and
    
 
   
             (3) upon redesignation of an Unrestricted Subsidiary as a
                 Restricted Subsidiary, the fair market value of such
                 Subsidiary; provided, however, that the sum of clauses (1), (2)
                 and (3) of clause (2) shall not exceed the aggregate amount of
                 all such Investments made subsequent to the Issue Date.
    
 
   
     Notwithstanding the foregoing, the provisions set forth above do not
prohibit:
    
 
     (1) the payment of any dividend within 60 days after the date of
         declaration of such dividend if the dividend would have been permitted
         on the date of declaration;
 
   
     (2) the acquisition of any shares of Capital Stock of Generac Portable
         Products, LLC, either (i) solely in exchange for shares of Qualified
         Capital Stock of Generac Portable Products, LLC or (ii) through the
         application of net proceeds of a substantially concurrent sale for cash
         (other than to a Subsidiary of Generac Portable Products, LLC) of
         shares of Qualified Capital Stock of Generac Portable Products, LLC;
    
 
   
     (3) the acquisition of any Indebtedness of Generac Portable Products, LLC
         that is subordinate or junior in right of payment to the new notes
         either (i) solely in exchange for shares of Qualified Capital Stock of
         Generac Portable Products, LLC or (ii) through the application of net
         proceeds of a substantially concurrent sale for cash (other than to a
         Subsidiary of Generac Portable Products, LLC) of (A) shares of
         Qualified Capital Stock of Generac Portable Products, LLC or (B)
         Refinancing Indebtedness;

         disability or termination of employment of such employees; provided
         that the aggregate amount of all such repurchases shall not exceed $3.0
         million in any fiscal year and $10.0 million in aggregate; provided,
         further, that at the time of any such repurchase, the Consolidated
         Fixed Charge Coverage Ratio of Generac Portable Products, LLC is
         greater than 2.0 to 1.0;
    
 
   
     (5) the payment of any dividend or distribution to the extent necessary to
         permit direct or indirect beneficial owners of shares of Capital Stock
         of Generac Portable Products, LLC, including Generac Portable Products,

         Portable Products, LLC and attributable to them solely as a result of
         Generac Portable Products, LLC (and any intermediate entity through
         which the holder owns such shares) being a limited liability company,
         partnership or similar entity for federal income tax purposes
         ("Permitted Tax Distributions"); and
    
 
   
     (6) any dividend or distribution to Generac Portable Products, Inc. in
         respect of overhead expenses, legal, accounting, SEC reporting and
         other professional fees and expenses of Generac Portable Products, Inc.
         directly attributable to the operations of Generac Portable Products,

     LIMITATION ON ASSET SALES.  Generac Portable Products, LLC will not, and
will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale
unless:
    
 
   
     (1) Generac Portable Products, LLC or the applicable Restricted Subsidiary,
         as the case may be, receives consideration at the time of such Asset
         Sale at least equal to the fair market value of the assets sold or
         otherwise disposed of (as determined in good faith by Generac Portable
         Products, LLC's Board of Directors);
    
 
   
     (2) at least 75% of the consideration received by Generac Portable
         Products, LLC or the Restricted Subsidiary, as the case may be, from
         such Asset Sale shall be in the form of cash or Cash Equivalents;
         provided that the amount of (x) any liabilities (as shown on Generac
         Portable Products, LLC's or such Restricted Subsidiary's most recent
         balance sheet) of Generac Portable Products, LLC or any Restricted
         Subsidiary (other than contingent liabilities and liabilities that are
         by their terms subordinated to the new notes or any guarantee thereof)
         that are assumed by the transferee of any such assets and (y) any
         securities, notes or other obligations received by Generac Portable
         Products, LLC or any such Restricted Subsidiary from such transferee
         that are converted within 180 days by Generac Portable Products, LLC or
         such Restricted Subsidiary into cash (to the extent of the cash
         received) shall be deemed to be cash for purposes of this provision;
         and
    
 
   
     (3) upon the consummation of an Asset Sale, Generac Portable Products, LLC
         shall apply, or cause such Restricted Subsidiary to apply, the Net Cash
         Proceeds relating to such Asset Sale within 270 days of receipt of such
         proceeds either:
    
 
   
        (a) to prepay any Senior Debt and, in the case of any Senior Debt under
            any revolving credit facility, effect a permanent reduction in the
            availability under such revolving credit facility;
    
 
   
        (b) to make an investment in properties and assets that replace the
            properties and assets that were the subject of such Asset Sale or in
            properties and assets that will be used in the business of Generac
            Portable Products, LLC and its Restricted Subsidiaries as existing
            on the Issue Date or in businesses reasonably related thereto
            ("Replacement Assets"); or
    
 
   
        (c) a combination of prepayment and investment permitted by clauses (a)
            and (b) above.
    
 
   
     On the 271st day after an Asset Sale or such earlier date, if any, as the
Board of Directors of Generac Portable Products, LLC or of such Restricted
Subsidiary determines
    
                                       78
<PAGE>   81
 
   
not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in
clauses (3)(a), (3)(b) and (3)(c) of the preceding paragraph (each, a "Net
Proceeds Offer Trigger Date"), such aggregate amount of Net Cash Proceeds that
is an integral multiple of $1,000 which has not been applied on or before such
Net Proceeds Offer Trigger Date as permitted in clauses (3)(a), (3)(b) and
(3)(c) of the preceding paragraph (each a "Net Proceeds Offer Amount") shall be
applied by Generac Portable Products, LLC or such Restricted Subsidiary to make
an offer to purchase (the "Net Proceeds Offer") on a date (the "Net Proceeds
Offer Payment Date") not less than 30 nor more than 60 days following the
applicable Net Proceeds Offer Trigger Date, from all holders on a pro rata
basis, that amount of notes equal to the Net Proceeds Offer Amount at a price
equal to 100% of the principal amount of the new notes to be purchased, plus
accrued and unpaid interest thereon, if any, to the date of purchase; provided,
however, that if at any time any non-cash consideration received by Generac
Portable Products, LLC or any Restricted Subsidiary of Generac Portable
Products, LLC, as the case may be, in connection with any Asset Sale is
converted into or sold or otherwise disposed of for cash (other than interest
received with respect to any such non-cash consideration), then such conversion
or disposition shall be deemed to constitute an Asset Sale hereunder and the Net
Cash Proceeds thereof shall be applied in accordance with this covenant.
    
 
   
     Generac Portable Products, LLC may defer the Net Proceeds Offer until there
is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess of
$10.0 million resulting from one or more Asset Sales (at which time, the entire
unutilized Net Proceeds Offer Amount, and not just the amount in excess of $10.0
million, shall be applied as required pursuant to this paragraph).
    
 
   
     In the event of the transfer of substantially all (but not all) of the
property and assets of Generac Portable Products, LLC and its Restricted
Subsidiaries as an entirety to a Person in a transaction permitted under
"-- Merger, Consolidation and Sale of Assets," the successor corporation shall
be deemed to have sold the properties and assets of Generac Portable Products,
LLC and its Restricted Subsidiaries not so transferred for purposes of this
covenant, and shall comply with the provisions of this covenant with respect to
such deemed sale as if it were an Asset Sale. In addition, the fair market value
of such properties and assets of Generac Portable Products, LLC or its
Restricted Subsidiaries deemed to be sold shall be deemed to be Net Cash
Proceeds for purposes of this covenant.
    
 
   
     Notwithstanding the preceding paragraphs of this covenant, Generac Portable
Products, LLC and its Restricted Subsidiaries will be permitted to consummate an
Asset Sale without complying with such paragraphs to the extent that:
    
 
   
     (1) at least 75% of the consideration for such Asset Sale constitutes
         Replacement Assets; and
    
 
   
     (2) such Asset Sale is for fair market value; provided that any
         consideration not constituting Replacement Assets received by Generac
         Portable Products, LLC or any of its Restricted Subsidiaries in
         connection with any Asset Sale permitted to be consummated under this
         paragraph shall constitute Net Cash Proceeds subject to the provisions
         of the preceding paragraphs of this covenant.
    
 
   
     Each Net Proceeds Offer will be mailed to the record holders as shown on
the register of holders within 25 days following the Net Proceeds Offer Trigger
Date, with a copy to the trustee, and shall comply with the procedures set forth
in the indenture. Upon receiving notice of the Net Proceeds Offer, holders may
elect to tender their notes in
    
 
                                       79
<PAGE>   82
 
   
whole or in part in integral multiples of $1,000 in exchange for cash. To the
extent holders properly tender notes in an amount exceeding the Net Proceeds
Offer Amount, notes of tendering holders will be purchased on a pro rata basis
(based on amounts tendered). A Net Proceeds Offer shall remain open for a period
of 20 business days or such longer period as may be required by law.
    
 
   
     The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of notes pursuant to a Net Proceeds Offer. To the extent that the
provisions of any securities laws or regulations conflict with the "Asset Sale"
provisions of the indenture, the Issuers shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under the "Asset Sale" provisions of the indenture by virtue
thereof.

SUBSIDIARIES. Generac Portable Products, LLC will not, and will not cause or
permit any of its Restricted Subsidiaries to, directly or indirectly, create or
otherwise cause or permit to exist or become effective any encumbrance or

        (e) any instrument governing Acquired Indebtedness, which encumbrance or

            assets of the Person so acquired;
    
 
   
        (f) agreements existing on the Issue Date to the extent and in the
            manner such agreements are in effect on the Issue Date;
    
 
   
        (g) an agreement governing Indebtedness incurred to Refinance the
            Indebtedness issued, assumed or incurred pursuant to an agreement
            referred to in clause (b), (c), (e) or (f) above; provided, however,
            that the provisions relating to such encumbrance or restriction
            contained in any such Indebtedness are no less favorable to Generac
            Portable Products, LLC in any material respect as determined by the
            Board of Directors of Generac Portable Products, LLC in their
            reasonable and good faith judgment than
    
 
                                       80

            in agreements referred to in such clause (b), (c), (e) or (f); or
    
 
   
        (h) any agreement or instrument governing Indebtedness (whether or not
            outstanding) of Foreign Restricted Subsidiaries incurred in reliance

            not more favorable to the lienholders with respect to such Liens

     All Affiliate Transactions (and each series of related Affiliate

     (2) transactions exclusively between or among Generac Portable Products,
         LLC and any of its Wholly Owned Restricted Subsidiaries or exclusively
         between or among such Wholly Owned Restricted Subsidiaries, provided
         such transactions are not otherwise prohibited by the indenture;
    
 
   
     (3) any agreement as in effect as of the Issue Date or any amendment
         thereto or any transaction contemplated thereby (including pursuant to
         any amendment thereto) in any replacement agreement thereto so long as
         any such amendment or replacement agreement is not more disadvantageous
         to the holders in any material respect than the original agreement as
         in effect on the Issue Date;
    
 
   
     (4) Restricted Payments permitted by the indenture; and
    
 
   
     (5) transactions with customers, clients, suppliers or purchasers or

         in the reasonable determination of the Board of Directors of Generac
         Portable Products, LLC, or at least as favorable as might reasonably
         have been obtained at such time from an unaffiliated party.
    
 
   
     LIMITATION OF GUARANTEES BY RESTRICTED SUBSIDIARIES.  Generac Portable
Products, LLC will not permit any of its Restricted Subsidiaries, directly or
indirectly, by way of the pledge of any intercompany note or otherwise, to
assume, guarantee or in any other manner become liable with respect to any
Indebtedness of Generac Portable Products, LLC or any other Restricted
Subsidiary of Generac Portable Products, LLC other than:
    
 
   
     (1) Indebtedness and other obligations under the Credit Agreement;

unless, in any such case:
    
 
   
     (a) such Restricted Subsidiary executes and delivers a supplemental
         indenture to the indenture, providing a guarantee of payment of the new
         notes by such Restricted Subsidiary (the "Guarantee") and
    
 
   
     (b) (x) if any such assumption, guarantee or other liability of such
         Restricted Subsidiary is provided in respect of Senior Debt, the
         guarantee or other instrument provided by such Restricted Subsidiary in
         respect of such Senior Debt may be superior to the Guarantee pursuant
         to subordination provisions no less favorable to the holders of the new
         notes than those contained in the indenture and (y) if such assumption,
         guarantee or other liability of such Restricted Subsidiary is provided
         in respect of Indebtedness that is expressly subordinated to the new
         notes, the guarantee or other instrument provided by such Restricted
         Subsidiary in respect of such subordinated Indebtedness shall be
         subordinated to the Guarantee pursuant to subordination provisions no
         less favorable to the holders of the new notes than those contained in
         the indenture.
    
 
   
     Notwithstanding the foregoing, any such Guarantee by a Restricted

         of all of Generac Portable Products, LLC's Capital Stock in, or all or
         substantially all of the assets of, such Restricted Subsidiary;
    
 
   
provided that (a) such sale or disposition of such Capital Stock or assets is
otherwise in compliance with the terms of the indenture and (b) such assumption,
guarantee or other liability of such Restricted Subsidiary has been released by
the holders of the other Indebtedness so guaranteed.

EVENTS OF DEFAULT
 
   
     The following events are defined in the indenture as "Events of Default":
    
 
   
     (1) the failure to pay interest on any notes when the same becomes due and
         payable and the default continues for a period of 30 days (whether or
         not such payment shall be prohibited by the subordination provisions of
         the indenture);
    
 
   
     (2) the failure to pay the principal on any notes, when such principal
         becomes due and payable, at maturity, upon redemption or otherwise
         (including the failure to make a payment to purchase notes tendered
         pursuant to a Change of Control Offer or a Net Proceeds Offer which has
         actually been made) (whether or not such payment shall be prohibited by
         the subordination provisions of the indenture);
    
 
   
     (3) a default in the observance or performance of any other covenant or
         agreement contained in the indenture which default continues for a
         period of 60 days after Generac Portable Products, LLC receives written
         notice specifying the default (and demanding that such default be
         remedied) from the trustee or the holders
    
 
                                       85
<PAGE>   88
 
   
         of at least 25% of the outstanding principal amount of the new notes
         (except in the case of a default with respect to the "Merger,
         Consolidation and Sale of Assets" covenant, which will constitute an
         Event of Default with such notice requirement but without such passage
         of time requirement);
    
 
   
     (4) the failure to pay at final maturity (giving effect to any applicable
         grace periods and any extensions thereof) the principal amount of any
         Indebtedness of Generac Portable Products, LLC or any Restricted
         Subsidiary of Generac Portable Products, LLC, or the acceleration of
         the final stated maturity of any such Indebtedness (which acceleration
         is not rescinded, annulled or otherwise cured within 20 days of receipt
         by Generac Portable Products, LLC or such Restricted Subsidiary of
         notice of any such acceleration) if the aggregate principal amount of
         such Indebtedness, together with the principal amount of any other such
         Indebtedness in default for failure to pay principal at final maturity
         or which has been accelerated, aggregates $10.0 million or more at any
         time;
    
 
   
     (5) one or more judgments in an aggregate amount in excess of $10.0 million
         shall have been rendered against Generac Portable Products, LLC or any
         of its Restricted Subsidiaries and such judgments remain undischarged,
         unpaid or unstayed for a period of 60 days after such judgment or
         judgments become final and non-appealable; or
    
 
   
     (6) certain events of bankruptcy affecting Generac Portable Products, LLC
         or any of its Significant Subsidiaries.
    
 
   
     If an Event of Default (other than an Event of Default specified in clause
(6) above with respect to Generac Portable Products, LLC) shall occur and be
continuing, the trustee or the holders of at least 25% in principal amount of
outstanding notes may declare the principal of and accrued interest on all the
new notes to be due and payable by notice in writing to Generac Portable
Products, LLC and the trustee specifying the respective Event of Default and
that it is a "notice of acceleration" (the "Acceleration Notice"), and the same:
    
 
   
     (1) shall become immediately due and payable or
    
 
   
     (2) if there are any amounts outstanding under the Credit Agreement, shall
         become immediately due and payable upon the first to occur of an
         acceleration under the Credit Agreement or 5 business days after
         receipt by Generac Portable Products, LLC and the Representative under
         the Credit Agreement of such Acceleration Notice but only if such Event
         of Default is then continuing.
    
 
   
     If an Event of Default specified in clause (4) above with respect to
Generac Portable Products, LLC occurs and is continuing, then all unpaid
principal of, and premium, if any, and accrued and unpaid interest on all of the
outstanding notes shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the trustee or any holder.
    
 
   
     The indenture provides that, at any time after a declaration of
acceleration with respect to the new notes as described in the preceding
paragraph, the holders of a majority in principal amount of the new notes may
rescind and cancel such declaration and its consequences:
    
 
   
     (1) if the rescission would not conflict with any judgment or decree;
    
 
   
     (2) if all existing Events of Default have been cured or waived except
         nonpayment of principal or interest that has become due solely because
         of the acceleration;
    
                                       86
<PAGE>   89
 
   
     (3) to the extent the payment of such interest is lawful, interest on
         overdue installments of interest and overdue principal, which has
         become due otherwise than by such declaration of acceleration, has been
         paid but only if such Event of Default is then continuing; and
    
 
   
     (4) if Generac Portable Products, LLC has paid the trustee its reasonable
         compensation and reimbursed the trustee for its expenses, disbursements
         and advances.
    
 
     No such rescission shall affect any subsequent Default or impair any right
consequent thereto.
 
   
     The holders of a majority in principal amount of the new notes may waive
any existing Default or Event of Default under the indenture, and its
consequences, except a default in the payment of the principal of or interest on
any notes.
    
 
   
     Holders of the new notes may not enforce the indenture or the new notes
except as provided in the indenture and under the Trust Indenture Act. Subject
to the provisions of the indenture relating to the duties of the trustee, the
trustee is under no obligation to exercise any of its rights or powers under the
indenture at the request, order or direction of any of the holders, unless such
holders have offered to the trustee reasonable indemnity. Subject to all
provisions of the indenture and applicable law, the holders of a majority in
aggregate principal amount of the then outstanding notes have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the trustee or exercising any trust or power conferred on the
trustee.
    
 
   
     Under the indenture, Generac Portable Products, LLC is required to provide
an officers' certificate to the trustee promptly upon any such officer obtaining
knowledge of any Default or Event of Default (provided that such officers shall
provide such certification at least annually whether or not they know of any
Default or Event of Default) that has occurred and, if applicable, describing
such Default or Event of Default and the status thereof.
    
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
   
     The Issuers may, at their option and at any time, elect to have their
obligations discharged with respect to the outstanding notes ("Legal
Defeasance"). Such Legal Defeasance means that the Issuers shall be deemed to
have paid and discharged the entire indebtedness represented by the outstanding
notes, except for:
    
 
   
     (1) the rights of holders to receive payments in respect of the principal
         of, premium, if any, and interest on the new notes when such payments
         are due;
    
 
   
     (2) the Issuers' obligations with respect to the new notes concerning
         issuing temporary notes, registration of notes, mutilated, destroyed,
         lost or stolen notes and the maintenance of an office or agency for
         payments;
    
 
   
     (3) the rights, powers, trust, duties and immunities of the trustee and the
         Issuers' obligations in connection therewith; and
    
 
   
     (4) the Legal Defeasance provisions of the indenture.
    
 
   
     In addition, the Issuers may, at their option and at any time, elect to
have the obligations of the Issuers released with respect to certain covenants
that are described in the indenture ("Covenant Defeasance") and thereafter any
omission to comply with such obligations shall not constitute a Default or Event
of Default with respect to the new
    
 
                                       87
<PAGE>   90
 
   
notes. In the event Covenant Defeasance occurs, certain events (not including
non-payment, bankruptcy, receivership, reorganization and insolvency events)
described under "Events of Default" will no longer constitute an Event of
Default with respect to the new notes.
    
 
   
     In order to exercise either Legal Defeasance or Covenant Defeasance:
    
 
   
     (1) the Issuers must irrevocably deposit with the trustee, in trust, for
         the benefit of the holders cash in U.S. dollars, non-callable U.S.
         government obligations, or a combination thereof, in such amounts as
         will be sufficient, in the opinion of a nationally recognized firm of
         independent public accountants, to pay the principal of, premium, if
         any, and interest on the new notes on the stated date for payment
         thereof or on the applicable redemption date, as the case may be;
    
 
   
     (2) in the case of Legal Defeasance, the Issuers shall have delivered to
         the trustee an opinion of counsel in the United States reasonably
         acceptable to the trustee confirming that:
    
 
   
        (a) the Issuers have received from, or there has been published by, the
            Internal Revenue Service a ruling or
    
 
   
        (b) since the date of the indenture, there has been a change in the
            applicable federal income tax law, in either case to the effect
            that, and based thereon such opinion of counsel shall confirm that,
            the holders will not recognize income, gain or loss for federal
            income tax purposes as a result of such Legal Defeasance and will be
            subject to federal income tax on the same amounts, in the same
            manner and at the same times as would have been the case if such
            Legal Defeasance had not occurred;
    
 
   
     (3) in the case of Covenant Defeasance, the Issuers shall have delivered to
         the trustee an opinion of counsel in the United States reasonably
         acceptable to the trustee confirming that the holders will not
         recognize income, gain or loss for federal income tax purposes as a
         result of such Covenant Defeasance and will be subject to federal
         income tax on the same amounts, in the same manner and at the same
         times as would have been the case if such Covenant Defeasance had not
         occurred;
    
 
   
     (4) no Default or Event of Default shall have occurred and be continuing on
         the date of such deposit or insofar as Events of Default from
         bankruptcy or insolvency events are concerned, at any time in the
         period ending on the 91st day after the date of deposit;
    
 
   
     (5) such Legal Defeasance or Covenant Defeasance shall not result in a
         breach or violation of, or constitute a default under the indenture or
         any other material agreement or instrument to which the Issuers or any
         of their Subsidiaries is a party or by which the Issuers or any of
         their Subsidiaries is bound;
    
 
   
     (6) each of the Issuers shall have delivered to the trustee an officers'
         certificate stating that the deposit was not made by the Issuers with
         the intent of preferring the holders over any other creditors of the
         Issuers or with the intent of defeating, hindering, delaying or
         defrauding any other creditors of the Issuers or others;
    
 
   
     (7) each of the Issuers shall have delivered to the trustee an officers'
         certificate and an opinion of counsel, each stating that all conditions
         precedent provided for or relating to the Legal Defeasance or the
         Covenant Defeasance have been complied with;
    
                                       88
<PAGE>   91
 
   
     (8) each of the Issuers shall have delivered to the trustee an opinion of
         counsel to the effect that:
    
 
   
        (a) the trust funds will not be subject to any rights of holders of
            Senior Debt, including, without limitation, those arising under the
            indenture, and
    
 
   
        (b) after the 91st day following the deposit, the trust funds will not
            be subject to the effect of any applicable bankruptcy, insolvency,
            reorganization or similar laws affecting creditors' rights
            generally; and
    
 
   
     (9) certain other customary conditions precedent are satisfied.
    
 
   
     Notwithstanding the foregoing, the opinion of counsel required by clause
(ii) above with respect to a Legal Defeasance need not be delivered if all notes
not theretofore delivered to the trustee for cancellation (x) have become due
and payable or (y) will become due and payable on the maturity date within one
year under arrangements satisfactory to the trustee for the giving of notice of
redemption by the trustee in the name, and at the expense, of Generac Portable
Products, LLC.
    
 
SATISFACTION AND DISCHARGE
 
   
     The indenture will be discharged and will cease to be of further effect
(except as to surviving rights or registration of transfer or exchange of the
new notes, as expressly provided for in the indenture) as to all outstanding
notes when:
    
 
   
     (1) either:
    
 
   
        (a) all the new notes theretofore authenticated and delivered (except
            lost, stolen or destroyed notes which have been replaced or paid and
            notes for whose payment money has theretofore been deposited in
            trust or segregated and held in trust by the Issuers and thereafter
            repaid to the Issuers or discharged from such trust) have been
            delivered to the trustee for cancellation or
    
 
   
        (b) all notes not theretofore delivered to the trustee for cancellation
            have become due and payable and the Issuers have irrevocably
            deposited or caused to be deposited with the trustee funds in an
            amount sufficient to pay and discharge the entire Indebtedness on
            the new notes not theretofore delivered to the trustee for
            cancellation, for principal of, premium, if any, and interest on the
            new notes to the date of deposit together with irrevocable
            instructions from the Issuers directing the trustee to apply such
            funds to the payment thereof at maturity or redemption, as the case
            may be;
    
 
   
     (2) the Issuers have paid all other sums payable under the indenture by the
         Issuers; and
    
 
   
     (3) each of the Issuers have delivered to the trustee an officers'
         certificate and an opinion of counsel stating that all conditions
         precedent under the indenture relating to the satisfaction and
         discharge of the indenture have been complied with.
    
 
MODIFICATION OF THE INDENTURE
 
   
     From time to time, the Issuers and the trustee, without the consent of the
holders, may amend the indenture for certain specified purposes, including
curing ambiguities, defects or inconsistencies, so long as such change does not,
in the opinion of the trustee, adversely affect the rights of any of the holders
in any material respect. In formulating its
    
 
                                       89
<PAGE>   92
 
   
opinion on such matters, the trustee will be entitled to rely on such evidence
as it deems appropriate, including, without limitation, solely on an opinion of
counsel. Other modifications and amendments of the indenture may be made with
the consent of the holders of a majority in principal amount of the then
outstanding notes issued under the indenture, except that, without the consent
of each holder affected thereby, no amendment may:
    
 
   
     (1) reduce the amount of notes whose holders must consent to an amendment;
    
 
   
     (2) reduce the rate of or change or have the effect of changing the time
         for payment of interest, including defaulted interest, on any notes;
    
 
   
     (3) reduce the principal of or change or have the effect of changing the
         fixed maturity of any notes, or change the date on which any notes may
         be subject to redemption or reduce the redemption price therefor;
    
 
   
     (4) make any notes payable in money other than that stated in the new
notes;
    
 
   
     (5) make any change in provisions of the indenture protecting the right of
         each holder to receive payment of principal of and interest on such
         note on or after the due date thereof or to bring suit to enforce such
         payment, or permitting holders of a majority in principal amount of
         notes to waive Defaults or Events of Default;
    
 
   
     (6) after Generac Portable Products, LLC's obligation to purchase notes
         arises thereunder, amend, change or modify in any material respect the
         obligation of Generac Portable Products, LLC to make and consummate a
         Change of Control Offer in the event of a Change of Control or make and
         consummate a Net Proceeds Offer with respect to any Asset Sale that has
         been consummated or, after such Change of Control has occurred or such
         Asset Sale has been consummated, modify any of the provisions or
         definitions with respect thereto; or
    
 
   
     (7) modify or change any provision of the indenture or the related
         definitions affecting the subordination or ranking of the new notes in
         a manner which adversely affects the holders.
    
 
GOVERNING LAW
 
   
     The indenture provides that it and the new notes will be governed by, and
construed in accordance with, the laws of the State of New York but without
giving effect to applicable principles of conflicts of law to the extent that
the application of the law of another jurisdiction would be required thereby.
    
 
THE TRUSTEE
 
   
     The indenture provides that, except during the continuance of an Event of
Default, the trustee will perform only such duties as are specifically set forth
in the indenture. During the existence of an Event of Default, the trustee will
exercise such rights and powers vested in it by the indenture, and use the same
degree of care and skill in its exercise as a prudent man would exercise or use
under the circumstances in the conduct of his own affairs.
    
 
   
     The indenture and the provisions of the Trust Indenture Act contain certain
limitations on the rights of the trustee, should it become a creditor of Generac
Portable Products, LLC, to obtain payments of claims in certain cases or to
realize on certain property received in respect of any such claim as security or
otherwise. Subject to the Trust Indenture Act, the trustee will be permitted to
engage in other transactions; provided
    
 
                                       90
<PAGE>   93
 
   
that if the trustee acquires any conflicting interest as described in the Trust
Indenture Act, it must eliminate such conflict or resign.

         as to any such Indebtedness, no such violation shall be deemed to exist
         for purposes of this clause (6) if the holder(s) of such obligation or
         their representative shall have received an officers' certificate of
         Generac Portable Products, LLC to the effect that the incurrence of
         such Indebtedness (or, in the case of revolving credit Indebtedness,
         that the entire committed amount thereof at the date on which the
         initial borrowing thereunder is made would not violate such provisions
         of the indenture);
    
 
   
     (7) Indebtedness which, when incurred and without respect to any election

     (9) any Indebtedness which is, by its express terms, subordinated in right
         of payment to any other Indebtedness of Generac Portable Products, LLC.

         not at the time of designation, and does not thereafter, create, incur,
         issue, assume, guarantee or otherwise become directly or indirectly

at any date, the number of years obtained by dividing (a) the then outstanding
aggregate principal amount of such Indebtedness into (b) the sum of the total of
the products obtained by multiplying (i) the amount of each then remaining

                          DESCRIPTION OF THE OLD NOTES
 
   
     The form and terms of the old notes are identical in all material respects
to the forms and terms of the new notes, except that:
    
 
   
     - the old notes have not been registered under the Securities Act of 1933,
       are subject to certain restrictions on transfer and are entitled to
       certain rights under the registration rights agreement (which rights will
       terminate upon consummation of the exchange offer, except under limited
       circumstances) and
    
 
   
     - the old notes will not provide for any increase in the interest rate.
    
 
   
     The old notes provide that, in the event that if a registration statement
relating to the exchange offer has not been filed on or by February 4, 1999 and
declared effective by April 5, 1999, then interest will accrue (in addition to
the stated interest rate on the old notes) at the rate of 0.50% per annum on the
principal amount of the notes for the period from the occurrence of such event
until such time as the exchange offer is consummated or any required shelf
registration statement is effective. The new notes are not, and upon
consummation of the exchange offer the old notes will not be, entitled to any
such additional interest. Holders of old notes should review the information set
forth under "Risk Factors -- Failure to Exchange Your Old Notes May Affect Your
Ability to Sell Them After the Completion of the Exchange Offer."
    
 
                    OLD NOTES REGISTRATION RIGHTS AGREEMENT
 
   
     The summary set forth below of the material provisions of the Registration
Rights Agreement does not purport to be complete and is qualified in its
entirety by reference to all the provisions of the Registration Rights
Agreement, which is filed as an exhibit to the registration statement of which
this prospectus is a part.
    
 
   
     The Issuers and the initial purchaser of the old notes entered into a
registration rights agreement concurrently with the issuance of the old notes.
The Issuers agreed, for the benefit of holders of the old notes, that they
would, at their expense, use their reasonable best efforts to:
    
 
   
     - file with the SEC within 210 days after the date of original issuance of
       the old notes (the "Issue Date") the registration statement of which this
       prospectus is a part with respect to the exchange offer to exchange the
       old notes for the new notes, and
    
 
   
     - cause the registration statement to be declared effective under the
       Securities Act of 1933 within 270 days after the Issue Date.
    
 
   
     Under the registration rights agreement, the Issuers are required to keep
the exchange offer open for at least 20 business days (or longer if required by
applicable law) after the date that notice of the exchange offer is mailed to
the holders of the old notes. For each old note surrendered for exchange, the
holder of the old note will receive a new note having a principal amount equal
to that of the surrendered old note.
    
 
   
     Interest on each new note will accrue from the later of (1) the last
interest payment date on which interest was paid on the old note surrendered in
exchange for the new note or (2) if the old note is surrendered for exchange on
a date in a period which includes the record date for an interest payment date
to occur on or after the date of such exchange and as to which interest will be
paid, the date of such interest payment date. If no interest
    
 
                                       108
<PAGE>   111
 
   
has been paid on such old note, however, interest on each new note will accrue
from the Issue Date.
    
 
   
     Each holder of old notes that wishes to exchange its old notes for new
notes must represent:
    
 
   
     - that any new notes to be received by it will be acquired in the ordinary
       course of its business;
    
 
   
     - that it has no arrangement or understanding with any person to
       participate in the distribution of the new notes in violation of the
       Securities Act of 1933; and
    
 
     - that it is not an "affiliate," as defined in Rule 405 under the
       Securities Act, of the Issuers.
 
   
If the holder is not a broker-dealer, it will be required to represent that it
is not engaged in, and does not intend to engage in, the distribution of new
notes. If the holder is a broker-dealer that will receive new notes for its own
account in exchange for old notes that were acquired as a result of
market-making or other trading activities (a "Participating Broker-Dealer"), it
will be required to acknowledge that it will deliver a prospectus in connection
with any resale of such new notes.
    
 
   
     The registration rights agreement also provides that the Issuers will make
available to Participating Broker-Dealers (and other persons, if any, with
similar prospectus delivery requirements) a prospectus meeting the requirements
of the Securities Act of 1933 for use in connection with any resale of new notes
for a period of 180 days after the completion of the exchange offer.
    
 
   
     In the event that:
    
 
   
     (1) the Issuers are not permitted to effect an exchange offer because of
         any change in law or in currently prevailing interpretations of the SEC
         staff,
    
 
   
     (2) the exchange offer is not consummated within 300 days of the Issue
         Date, or
    
 
   
     (3) in the case of any holder that participates in the exchange offer, such
         holder does not receive new notes on the date of the exchange that may
         be sold without restriction under state and federal securities laws
         (other than due solely to the status of such holder as an affiliate of
         the Issuers within the meaning of the Securities Act),
    
 
   
then, in each case, the Issuers will promptly deliver to the holders and the
trustee written notice of such event and shall at their sole expense:
    
 
   
     - as promptly as practicable file with the SEC a shelf registration
       statement covering resales of the old notes,
    
 
   
     - use their reasonable best efforts to cause the shelf registration
       statement to be declared effective under the Securities Act of 1933, and
    
 
   
     - use their reasonable best efforts to keep effective the shelf
       registration statement until the earlier of two years after the Issue
       Date or such time as all of the applicable old notes have been sold under
       the shelf registration statement.
    
 
   
     The Issuers will, in the event that a shelf registration statement is
filed, provide to each holder of the old notes copies of the prospectus that is
a part of the shelf registration statement, notify each such holder when the
shelf registration statement for the old notes has become effective and take
certain other actions as are required to permit unrestricted
    
 
                                       109
<PAGE>   112
 
   
resales of the old notes. A holder that sells old notes pursuant to the shelf
registration statement will be required to be named as a selling securityholder
in the related prospectus and to deliver a prospectus to purchasers, will be
subject to certain of the civil liability provisions under the Securities Act of
1933 in connection with such sales and will be bound by the provisions of the
registration rights agreement that are applicable to such holder (including
certain indemnification rights and obligations).
    
 
   
     In the event that:
    
 
   
     (1) the registration statement is not filed with the SEC within 210 days
         after the Issue Date or, if the Issuers are required to file a shelf
         registration statement, such shelf registration statement is not filed
         on or before the 60th day after the date on which the obligation to
         file such shelf registration statement arises,
    
 
   
     (2) the registration statement is not declared effective within 270 days
         after the Issue Date or, if the Issuers are required to file a shelf
         registration statement, such shelf registration statement is not
         declared effective on or before the 270th day after the date on which
         the obligation to file such shelf registration statement arises,
    
 
   
     (3) the exchange offer is not consummated on or prior to the later of the
         45th day after the date on which the registration statement was
         declared effective or the 300th day after the Issue Date, or
    
 
   
     (4) if applicable, the shelf registration statement is filed and declared
         effective but ceases to remain effective at any time prior to the
         second anniversary of the Issue Date, other than after such time as all
         old notes have been disposed of under such shelf registration
         statement,
    
 
   
then the Issuers will be required to pay additional interest on the principal
amount of the old notes at the rate of .50% per annum for the first 90 days
immediately following each applicable date. Such additional interest rate shall
increase by an additional .50% per annum at the beginning of each subsequent
90-day period. The additional interest rate on the old notes, however, may not
exceed in the aggregate 1.00% per annum. Such additional interest shall cease to
accrue when:
    
 
   
     (1) the registration statement or shelf registration statement is filed,
    
 
   
     (2) the registration statement or the shelf registration statement is
         declared effective,
    
 
   
     (3) the exchange offer is consummated, or
    
 
   
     (4) the shelf registration statement again becomes effective, as the case
         may be.
    
 
                         BOOK-ENTRY; DELIVERY AND FORM
 
   
     The certificates representing the notes will be issued in fully registered
form without interest coupons.
    
 
   
     Except as set forth below, the new notes will be represented by one or more
permanent global notes in fully registered form without interest coupons and
will be deposited with the trustee as custodian for DTC and registered in the
name of a nominee of such depositary.
    
 
                                       110
<PAGE>   113
 
THE GLOBAL NOTES
 
   
     The Issuers expect that pursuant to procedures established by DTC (i) upon
the issuance of the global notes, DTC or its custodian will credit, on its
internal system, the principal amount at maturity of the individual beneficial
interests represented by such global notes to the respective accounts of persons
who have accounts with such depositary and (ii) ownership of beneficial
interests in the global notes will be shown on, and the transfer of such
ownership will be effected only through, records maintained by DTC or its
nominee (with respect to interests of participants) and the records of
participants (with respect to interests of persons other than participants).
    
 
   
     So long as DTC, or its nominee, is the registered owner or holder of the
notes, DTC or such nominee, as the case may be, will be considered the sole
owner or holder of the notes represented by such global notes for all purposes
under the indenture. No beneficial owner of an interest in the global notes will
be able to transfer that interest except in accordance with DTC's procedures, in
addition to those provided for under the indenture.
    
 
   
     Payments of the principal of, premium (if any), and interest on, the global
notes will be made to DTC or its nominee, as the case may be, as the registered
owner thereof. None of the Issuers, the Trustee or any paying agent will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the global notes
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.
    
 
   
     The Issuers expect that DTC or its nominee, upon receipt of any payment of
principal, premium, if any, or interest on the global notes, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount at maturity of the
global notes as shown on the records of DTC or its nominee. The Issuers also
expect that payments by participants to owners of beneficial interests in the
global notes held through such participants will be governed by standing
instructions and customary practice, as is now the case with securities held for
the accounts of customers registered in the names of nominees for such
customers. Such payments will be the responsibility of such participants.
    
 
   
     Transfers between participants in DTC will be effected in the ordinary way
through DTC's same-day funds system in accordance with DTC rules and will be
settled in same day funds. If a holder requires physical delivery of a
certificated security for any reason, including to sell notes to persons in
states that require physical delivery of the notes, or to pledge such
securities, such holder must transfer its interest in the global notes, in
accordance with the normal procedures of DTC and with the procedures set forth
in the applicable indenture.
    
 
   
     DTC has advised the Issuers that it will take any action permitted to be
taken by a holder of notes (including the presentation of notes for exchange as
described below) only at the direction of one or more participants to whose
accounts the DTC interests in the global notes are credited and only in respect
of such portion of the aggregate principal amount at maturity of notes as to
which such participant or participants has or have given such direction.
However, if there is an event of default under the indenture, DTC will exchange
the global notes for certificated securities, which it will distribute to its
participants.
    
 
   
     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the global notes among participants of DTC, it is
under no obligation to perform such procedures and such procedures may be
discontinued at any time. Neither
    
 
                                       111
<PAGE>   114
 
   
the Issuers nor the Trustee for the notes will have any responsibility for the
performance by DTC or its participants or indirect participants of their
respective obligations under the rules and procedures governing their
operations.
    
 
CERTIFICATED SECURITIES
 
   
     Certificated securities shall be issued in exchange for beneficial
interests in the global notes (i) if requested by a holder of such interests or
(ii) if DTC is at any time unwilling or unable to continue as a depositary for
the global notes and a successor depositary is not appointed by the Issuers
within 90 days.
    
 
             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
   
     The following discussion expresses the opinion of King & Spalding, counsel
to the Company, as to certain United States federal income tax consequences of
the exchange, holding and disposition of the new notes. This discussion is based
on the Internal Revenue Code, Treasury Regulations (including proposed
regulations) promulgated thereunder, administrative pronouncements and judicial
decisions each as now in effect, all of which are subject to change, possibly
with retroactive effect. This discussion does not purport to deal with all
aspects of United States federal income taxation that may be relevant to holders
of new notes in light of such holders' personal circumstances. This summary
deals only with United States persons that will acquire new notes pursuant to
the terms of the exchange offer and will hold new notes as capital assets and
does not address tax considerations applicable to investors that may be subject
to special tax rules, such as financial institutions, S corporations, tax-exempt
organizations, insurance companies, dealers in securities or currencies, persons
other than United States persons or persons that will hold new notes as a
position in a "straddle," as part of a hedging transaction for tax purposes, as
part of a "synthetic debt instrument" or other integrated investment (including
a "conversion transaction") or holders that have a "functional currency" other
than the United States dollar. No ruling on any of the issues discussed below
will be sought from the United States Internal Revenue Services (the "IRS").
    
 
EXCHANGE OF NEW NOTES
 
   
     The exchange of old notes for the new notes pursuant to the exchange offer
will not be treated as an "exchange" for federal income tax purposes, because
the new notes do not differ materially in kind or extent from the old notes.
Rather, the new notes received by a holder will be treated as a continuation of
the old notes in the hands of such holder. As a result, no gain or loss will be
recognized on the exchange of old notes for new notes pursuant to the exchange
offer.
    
 
INTEREST ON NEW NOTES
 
   
     A holder of a new note generally will be required to report as ordinary
interest income for federal income tax purposes interest earned on the new note
in accordance with the holder's method of tax accounting.
    
 
DISPOSITION OF NEW NOTES
 
   
     A holder's tax basis for a new note will be the holder's tax basis for the
old note immediately before the exchange. A holder's tax basis for the old note
immediately before the exchange generally will equal the cost of the old note to
the holder, reduced by any amortized bond premium (as described below) and any
payments other than interest made
    
                                       112
<PAGE>   115
 
   
on the old note and increased by any market discount (as described below)
included in the holder's income. Upon the sale, exchange or retirement of a new
note, a holder generally will recognize gain or loss equal to the difference
between the amount realized on the sale, exchange or retirement (less the amount
attributable to any accrued but unpaid interest on the new note, which amount
will be taxable as interest if it has not been included in income under such
holder's method of accounting) and the holder's tax basis in the new note.
Except as discussed below with respect to gain attributable to market discount,
gain or loss will be long-term capital gain or loss if, on the date of the sale,
a holder has a holding period for the new note (which would include the holding
period of the old note) of more than one year. Otherwise, except as discussed
below with respect to gain attributable to market discount, the gain or loss
will be short-term capital gain or loss.
    
 
AMORTIZABLE BOND PREMIUM AND MARKET DISCOUNT
 
   
     A note acquired with an adjusted basis (for purposes of determining loss on
a sale or exchange) in excess of the outstanding principal amount of the note at
the time of acquisition will be considered to have amortizable bond premium. A
holder of a note acquired with such premium generally may elect to amortize such
premium as an offset to interest income, using a constant yield method, over the
remaining term of the note. Corresponding adjustments are made to such holder's
basis in the note. This election would apply to all taxable debt instruments
held by such holder at the beginning of the taxable year in which the election
applies and to all taxable debt instruments thereafter acquired.
    
 
   
     A note acquired with an adjusted basis that is less than its outstanding
principal amount at the time of acquisition by more than a de minimis amount
will be considered to have "market discount" in the hands of the acquiring
holder. Under the de minimis exception, there is no market discount if the
excess of the outstanding principal amount of the note over the holder's tax
basis in the note is less than .25% of the principal amount multiplied by the
number of complete years after the acquisition date to the maturity date of the
note. Market discount generally accrues ratably during the period immediately
after the date of acquisition up to (and including) the maturity date of the
note, unless the holder elects to accrue such discount on the basis of the
constant interest method.
    
 
   
     The holder of a note acquired at a market discount will be required to
treat all or a portion of the gain, if any, realized upon the sale or other
disposition of the note as ordinary income to the extent of accrued market
discount. If a holder's interest expense deductions for a taxable year
attributable to indebtedness treated as incurred or continued to purchase or
carry a note acquired at a market discount exceed interest and market discount
included in income with respect to the note for such taxable year, a holder may
be required to defer all or a portion of such excess. The rules described above
with respect to the recharacterization of gain realized on a disposition of a
note and deferral of interest expense will not apply if the holder elects to
include market discount in income currently as it accrues. Such election, if
made, applies with respect to all market discount bonds acquired by the holder
on or after the first day of the first taxable year to which the election
applies and is irrevocable without the consent of the IRS.
    
 
   
     Holders who were subject to the bond premium and market discount provisions
discussed above with respect to the old notes will continue to be subject to
those provisions with respect to the new notes received in exchange for old
notes under the exchange offer. Holders should consult their own tax advisors
regarding the specific application of those provisions to the notes acquired at
a premium or at a discount.

<PAGE>   116
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
   
     A 31% "backup" withholding and information reporting requirements apply to
certain holders with respect to certain payments of principal, interest and
premium on a debt instrument and proceeds from the sale, redemption, or
retirement of a debt instrument. A holder of a new note may be subject to backup
withholding at the rate of 31% with respect to interest paid on the new note and
proceeds from the sale, exchange, redemption or retirement of the new note,
unless such holder (a) is a corporation or comes within certain other exempt
categories and , when required, demonstrates that fact or (b) provides a correct
taxpayer identification number, certifies as to exemption from backup
withholding and otherwise complies with applicable requirements of the backup
withholding rules. A holder of a new note who does not provide the Issuers with
his correct taxpayer identification number may be subject to penalties imposed
by the IRS. Any amount paid as backup withholding will be creditable against the
holder's federal income tax liability provided that the required information is
furnished to the IRS.
    
 
   
     EACH HOLDER SHOULD BE AWARE THAT THE FOREGOING DISCUSSION DOES NOT ADDRESS
ALL ASPECTS OF UNITED STATES FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO A

HOLDER SHOULD CONSULT SUCH HOLDER'S OWN TAX ADVISOR AS TO THE SPECIFIC FEDERAL,
STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES OF THE OWNERSHIP AND
DISPOSITION OF THE NEW NOTES.

                              PLAN OF DISTRIBUTION
 
   
     Each broker-deal that receives new notes for its own account in connection
with the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of such new notes. This prospectus, as it may be
amended or supplemented from time to time, may be used by Participating
Broker-Dealers during the period referred to below in connection with resales of
new notes received in exchange for old notes if such old notes were acquired by
such Participating Broker-Dealers for their own accounts as a result of
market-making activities or other trading activities. The Issuers have agreed
that this prospectus, as it may be amended or supplemented from time to time,
may be used by a Participating Broker-Dealer in connection with resales of such
new notes for a period ending 90 days (subject to extension under certain
limited circumstances described herein) after the Expiration Date or, if
earlier, when all such new notes have been disposed of by such Participating
Broker-Dealer. However, a Participating Broker-Dealer who intends to use this
prospectus in connection with the resale of new notes received in exchange for
old notes pursuant to the exchange offer must notify the Issuers, or cause the
Issuers to be notified, on or prior to the Expiration Date, that it is a
Participating Broker-Dealer. Such notice may be given in the space provided for
that purpose in the Letter of Transmittal or may be delivered to the exchange
agent at one of the addresses set forth herein under "The Exchange
Offer -- Exchange Agent." See "The Exchange Offer -- Resales of New Notes."
    
 
   
     The Company will not receive any cash or other proceeds from the issuance
of the new notes offered hereby. New notes received by broker-dealers for their
own accounts in connection with the exchange offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the new notes or a combination
of such methods of resale, at market prices prevailing at the time of resale, at
prices related to such prevailing market prices or at negotiated prices. Any
such resale may be made directly to purchasers or to or through brokers or
dealers who may receive compensation in the form of commissions or concessions
from any such broker-dealer and/or the purchasers of any such new notes. Any
broker-dealer that resells new notes that were received by it for its own
account in connection with the exchange offer and any broker or dealer that
participates in a distribution of such new notes may be deemed to be an
"underwriter" within the meaning of the Securities Act, and any profit on any
such resale of new notes and any commissions or concessions received by any such
persons may be deemed to be underwriting compensation under the Securities Act.
The Letter of Transmittal states that by acknowledging that it will deliver and
by delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
  of Generac Portable Products, Inc.
 
     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of income, of changes in stockholders' equity
and of cash flows present fairly, in all material respects, the financial
position of Generac Portable Products, Inc. and its subsidiaries at December 31,
1998 and July 9, 1998, and the results of their operations and their cash flows
for the period July 10, 1998 through December 31, 1998, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (DOLLAR AMOUNTS IN THOUSANDS UNLESS INDICATED)
 
1.  FORMATION OF THE COMPANY AND NATURE OF BUSINESS
 
   
     Generac Portable Products, Inc. (the "Company"), a Delaware corporation,
was formed on April 29, 1998 by an investor group organized by The Beacon Group
III - Focus Value Fund L.P. ("The Beacon Group") for the purpose of acquiring,
through its indirect wholly-owned limited liability company, Generac Portable
Products, LLC, net assets of the Portable Products Division of Generac
Corporation. The primary business activity of the Company consists of its
indirect ownership of 100% of the limited liability company interests in Generac
Portable Products, LLC, a Delaware limited liability company, through two
wholly-owned subsidiaries: GPPW, Inc. a Wisconsin corporation, and GPPD, Inc. a
Delaware corporation. GPPW, Inc. and GPPD, Inc. hold, respectively, 5% and 95%
limited liability company interests in Generac Portable Products, LLC. The
Company had no operations during the period April 29, 1998 through July 8, 1998;
its only business activity involved the issuance of $110 million of common stock
to finance a portion of the purchase price discussed below.
    
 
   
     On July 9, 1998, the Company caused Generac Portable Products, LLC to
purchase substantially all of the assets, and assume certain of the liabilities,
of the Portable Products Division (the "Predecessor") of Generac Corporation
(the "Acquisition"). The aggregate consideration paid for the net assets of the
Predecessor was approximately $330 million, which includes cash acquired of $.6
million, direct acquisition costs of $1.4 million and assumed liabilities of
$23.9 million. The purchase price paid for the Predecessor was subject to a
post-closing adjustment based on net working capital at July 9, 1998, as
defined. The Company has recorded a receivable of $1.0 million at December 31,
1998 relating to this adjustment.
    
 
     The Acquisition has been accounted for using the purchase method of
accounting and accordingly, the purchase price has been allocated to
identifiable assets acquired and liabilities assumed based upon their estimated
fair values, subject to certain limitations (see Note 2), with the excess
purchase price recorded as goodwill. Goodwill of approximately $214 million has
been recorded as a result of the Acquisition.
 
     The following table sets forth the pro forma information for the Company as
if the Acquisition had occurred on January 1, 1998. This information is
unaudited and does not purport to represent actual sales or net income had the
Acquisition actually occurred on January 1, 1998.

     In addition to the issuance of common stock by the Company, the purchase
price was financed through the issuance of senior subordinated notes of $110
million and borrowings of $96.6 million under a $115 million bank credit
facility (see Note 7).

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company, with domestic operations located in Jefferson, Wisconsin and
branch operations in the United Kingdom and Germany, is a leader in the design,
manufacture and sale of portable generators and pressure washers for use in both
industrial and residential applications.
 
2.  SIGNIFICANT ACCOUNTING POLICIES
 
     USE OF ESTIMATES:  The Company prepares its financial statements in
conformity with generally accepted accounting principles, which require
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities, disclosures of contingent assets and liabilities at the
date of the financial statements, and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
     PRINCIPLES OF CONSOLIDATION:  The Company's consolidated financial
statements include the accounts of its wholly-owned subsidiaries. All
significant intercompany transactions and balances have been eliminated.
 
   
     BASIS OF ACCOUNTING:  Pursuant to the Financial Accounting Standards
Board's Emerging Issues Task Force Issue No. 88-16, "Basis in Leveraged Buyout
Transactions," the Company has limited its accounting basis resulting from the
Acquisition as a result of certain shareholders which also held an interest in
the Predecessor through ownership interests in Generac Corporation. Such
limitation was based upon the lesser of each continuing shareholder's interest
in the Company or the Predecessor, and the Predecessor's historical book value
at July 9, 1998. The difference between the continuing shareholders' basis in
the Predecessor and their proportionate equity in the book value of the
Predecessor was not material. The difference between the total consideration
paid in connection with the Acquisition and the accounting basis recognized is
reported as a separate component of stockholders' equity.
    
 
     CASH AND CASH EQUIVALENTS:  The Company considers all investments with a
maturity of three months or less at the date of purchase to be cash equivalents.
 
     INVENTORIES:  Inventories are stated at the lower of cost (first-in,
first-out method) or market (replacement cost or estimated net realizable
value).
 
     RESEARCH AND DEVELOPMENT COSTS:  The Company has an ongoing program of new
product development and existing product enhancement through redesign of
existing products and the addition of new models. Costs related to these
programs are expensed as incurred and totaled $1,011 for the period ended
December 31, 1998. Costs related to manufacturing start-up activities for new
products are included in cost of sales as incurred.
 
     PROPERTY, PLANT AND EQUIPMENT:  Property, plant and equipment is recorded
at cost and includes equipment under leases which have been capitalized.
Maintenance and repair costs are charged to expense as incurred. Gains and
losses on disposition of property, plant and equipment are reflected in income.
Depreciation of property, plant and equipment are

recorded using principally the straight-line method for financial reporting
purposes over the estimated useful lives of the assets or terms of related
leases as follows:

     INTANGIBLE ASSETS:  Goodwill, representing the recognized portion of the
cost of the Acquisition in excess of the fair values assigned to identifiable
net assets acquired, is being amortized on a straight-line basis over 40 years.
The non-compete agreement and patents and trademarks are being amortized on a
straight-line basis over 10 years. The Company assesses the carrying value of
goodwill and other intangibles at each balance sheet date. Consistent with
Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of", such assessments include, as appropriate, a comparison of (a) the estimated
future nondiscounted cash flows anticipated to be generated during the remaining
amortization period to (b) the net carrying value of the asset. Impairment
assessments of goodwill made in accordance with SFAS No. 121 are made in
connection with an analysis of related long-lived assets acquired in the
Acquisition when events or changes in circumstances indicate the carrying amount
of either asset may not be recoverable. The Company recognizes impairment losses
resulting from diminution in value, if any, on a current basis based upon the
estimated fair value of the related assets.
    
 
     DEFERRED FINANCING COSTS:  Expenses associated with the issuance of debt
instruments are capitalized and are being amortized over the terms of the
respective financing arrangement using the effective interest rate and
straight-line methods over periods ranging from 5 to 8 years.
 
     INTEREST RATE SWAPS:  To limit the effect of increases in interest rates,
the Company has entered into an interest rate swap arrangement. The differential
between the contract floating and fixed rates is accrued each period and
recorded as an adjustment of interest expense.
 
     PRODUCT WARRANTIES:  The Company provides that warranted products are
merchantable and free of defects in workmanship and material generally for a
period of one year. Warranty reserves are provided as charges to operations
under selling and service expense for estimated normal warranty costs and, if
applicable, for any significant problems known to exist on products sold.
Warranty expense totaled $1,989 for the period ended December 31, 1998.
 
     INCOME TAXES:  Deferred income tax assets and liabilities are determined
based upon the difference between the financial statement and tax bases of
assets and liabilities, as measured by enacted tax rates which will be in effect
when these differences are expected to reverse. Deferred income tax expense is
the result of changes in the deferred tax assets

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
and liabilities. A valuation allowance is provided when it is considered more
likely than not that some portion or all of recorded deferred income tax assets
will not be realized.
 
     FAIR VALUE OF FINANCIAL INSTRUMENTS:  The carrying amounts reported in the
consolidated balance sheets for cash and cash equivalents, accounts receivable,
accounts payable, and short-term borrowings approximate fair value due to the
short-term maturity of these financial instruments. The amounts reported for
borrowings under the bank credit facility approximate fair value since the
underlying instruments bear interest at a variable rate that reprices
frequently. The fair value of the Company's senior subordinated notes at
December 31, 1998 is estimated based upon the average yield on similar debt
instruments as of such date. The fair value of the interest rate swap
arrangement is the amount at which it could be settled, based on a quote
obtained from the respective financial institution (see Note 7).
 
     REVENUE RECOGNITION:  Net sales and costs of sales are recognized as the
related products are shipped. Provisions for estimated sales returns and sales
incentives are recorded in the period in which the sales are recognized.
 
     FOREIGN CURRENCY TRANSLATION:  The translation of the assets and
liabilities of the Company's international branch operations into U.S. dollars
is performed for balance sheet accounts using current exchange rates in effect
at the balance sheet date and for revenue and expense accounts using an average
exchange rate during the period. The gains or (losses) resulting from such
translation are reflected as translation adjustments in accumulated other
comprehensive income.
 
     FUTURE ACCOUNTING CHANGES:  The Financial Accounting Standards Board has
issued SFAS No. 133 "Accounting for Derivative Instruments and Hedging
Activities" which is effective for periods beginning after June 15, 1999. Due to
the Company's current limited use of derivative instruments, the adoption of
this statement is not expected to have a material effect on the Company's
financial condition or results of operations.

     In connection with the Acquisition, the Company entered into a $115 million
bank credit facility (the "Senior Secured Credit Facility"). The Senior Secured
Credit Facility provides for maximum borrowings under two term loans of $45
million ("A Term Loan") and $40 million ("B Term Loan"), respectively, with
balances outstanding at December 31, 1998 of $45 million and $39.8 million,
respectively. The Senior Secured Credit Facility also provides for maximum
borrowings of $30 million, less the amount outstanding under letters of credit,
under revolving loan arrangements due December 31, 2003, with a balance
outstanding at December 31, 1998 of $600. The A Term Loan will mature 5 1/2
years from July 9, 1998. The B Term Loan will mature seven years from July 9,
1998. The A Term Loan will provide for amortization of $2.5 million in the first
year, $6.25 million in the second year, $7.5 million in the third year, $10.0
million in the fourth year, $12.5 million in the fifth year and $6.25 million in
the sixth year. The B Term Loan will provide for nominal annual amortization in
the first five years and amortization of $19 million in each of the sixth and
seventh years. Additionally, the Company is also required to make an annual
principal payment equal to its excess cash flow, as defined. The required excess
cash flow payment for the period ended December 31, 1998 is approximately $2.1
million and will be applied to reduce the scheduled repayments under both the A
and B Term Loan Facilities described above, on a pro rata basis. The interest
rates under the A Term Loan and the revolving loan portion of the facility will
be based, at the option of Generac Portable Products, LLC, on

either a Eurodollar rate plus 2.25% per annum or a base rate plus 1.25% per
annum, subject to a pricing grid that will provide for reductions in the
applicable interest rate margins based on the Company's consolidated debt to
earnings before interest, income taxes, depreciation and amortization ("EBITDA")
ratio. The interest rate under the B Term Loan is based, at the option of
Generac Portable Products, LLC, on a Eurodollar rate plus 2.75% or a base rate
plus 1.75%, subject to a pricing grid that will provide for reductions in the
applicable interest rate margins based on the Company's consolidated debt to
EBITDA ratio. The weighted average interest rate for the term loans as of
December 31, 1998 was 7.84%. Borrowings under the revolving loans bear interest
at the Prime Rate plus 1.25% (9% at December 31, 1998). A commitment fee of
0.50% per annum will be charged on the unused revolving loan portion of the
Senior Secured Credit Facility, subject to a pricing grid that will provide for
reductions in the applicable commitment fee margin based on the Company's
consolidated debt to EBITDA ratio. Substantially all of the Company's assets are
pledged as collateral under the Senior Secured Credit Facility.
    
 
     Effective October 15, 1998, the Company entered into an interest rate swap
agreement with a major financial institution to reduce the impact of changes in
interest rates on its floating rate long-term debt. The notional amount of this
agreement was $40 million at December 31, 1998. Interest expense has been
adjusted for the net amount payable under this agreement. The effect of this
agreement on the Company's interest expense for the period ended December 31,
1998 was not significant. The fair value of the interest rate swap agreement was
$903 at December 31, 1998, which is the amount the Company would have paid to
settle the instrument at such date. The Company is exposed to credit loss in the
event of non-performance by the financial institution, however, management does
not anticipate such non-performance.
 
     Also on July 9, 1998, the Company issued $110 million of 11.25% Senior
Subordinated Notes due June 30, 2006, (the "Notes") to BT Alex. Brown,
Incorporated (the "Initial Purchaser"). The Initial Purchaser subsequently
resold the Notes to qualified institutional buyers pursuant to Rule 144A of the
Securities Exchange Act and to a limited number of institutional accredited
investors that agreed to comply with certain transfer restrictions and other
conditions. The estimated fair value of the Notes at December 31, 1998
approximates par.
 
     The Notes are redeemable, at the Company's option, in whole at any time or
in part from time to time, on and after July 1, 2002, upon not less than 30 nor
more than 60 days' notice, at the following redemption prices (expressed as
percentages of the principal amount thereof) if redeemed during the twelve-month
period commencing on July 1 of the year set forth below, plus, in each case,
accrued and unpaid interest thereon, if any, to the date of redemption:

     At any time, or from time to time, on or prior to July 1, 2001, the Company
may, at its option, use the net cash proceeds of one or more Public Equity
Offerings, as defined, to redeem the Notes at a redemption price equal to
111.25% of the principal amount thereof plus accrued and unpaid interest
thereon, if any, to the date of redemption; provided that at least 65% of the
principal amount of Notes originally issued remains outstanding immediately
after any such redemption.
 
   
     The Senior Secured Credit Facility and the indenture governing the Notes
contain a number of covenants that, among other things, restrict the ability of
the Company to dispose of assets, repay other indebtedness, incur additional
indebtedness, pay dividends, prepay subordinated indebtedness (including, in the
case of the Senior Secured Credit Facility, the Notes), incur liens, make
capital expenditures and make certain investments or acquisitions, engage in
mergers or consolidations, engage in certain transactions with affiliates and
otherwise restrict the activities of the Company. In addition, under the Senior
Secured Credit Facility, Generac Portable Products, LLC will be required to
satisfy specified financial ratios and tests, including a minimum level of
earnings before interest, income taxes, depreciation and amortization.
    
 
     Capital lease obligations relate to the Company's obligations on leases for
industrial equipment. These obligations are due in monthly installments
including principal and interest at a rate of 8.6% and mature November 30, 2002.

8.  EMPLOYEE RETIREMENT AND SAVINGS PLANS
 
     In connection with the Acquisition, the Company established noncontributory
defined benefit pension plans (salaried and hourly) covering substantially all
of its employees. The unfunded benefit obligation assumed as of the Acquisition
date totaled $678. Benefits under the salaried plan are based upon years of
service and the participants' defined final average monthly compensation.
Benefits under the hourly plan are based on a unit amount at the date of
termination multiplied by the participants' credited service. The plans provide
for a continuation of participants' years of service as credited with Generac
Corporation. The Company's funding policy is to contribute amounts that equal or
exceed the minimum requirements of the Employee Retirement Income Security Act
of 1974 (ERISA). As of December 31, 1998 and July 9, 1998, no assets have been
contributed to

10.  STOCKHOLDERS' EQUITY
 
   
     In connection with the initial capitalization of the Company, The Beacon
Group III -- Focus Value Fund, L.P. ("The Beacon Group"), management of the
Company and certain other investors purchased an aggregate of $110 million of
common stock, par value of $.01 per share, constituting 100% of the Company's
outstanding common stock. Upon consummation of the Acquisition, The Beacon Group
and the other stockholders of the Company, and the Company, entered into a
Stockholders' Agreement which includes certain transfer restrictions, voting
agreements and registration rights. Employees who own stock of the Company are
also subject to agreements that restrict their right to transfer their stock
and, under certain conditions, require them to sell a pro rata portion of their
stock in a transaction in which The Beacon Group is selling its stock. The
Company is not obligated to purchase this stock.
    
 
     Effective July 9, 1998, the Company's board of directors approved the
Generac Portable Products, Inc. Stock Option Plan which provides for the
granting of stock options as an incentive to certain key employees. Under this
Plan, stock options to acquire up to 1,619 shares of common stock, in the
aggregate, may be granted under a time-vesting formula at an exercise price
equal to the fair market value of the common stock at the date of grant. The
options become exercisable in equal increments beginning on the first
anniversary of the grant date over a five-year period and expire ten years
subsequent to the

grant date. On July 9, 1998, 1,063 options were granted at an exercise price of
$12,941.00 per share to certain members of management and the Company's board of
directors. The options have a remaining contractual life of 9.5 years. No
options were granted or forfeited subsequent to the initial grant. The fair
value of the options at the date of grant was $4,335.00 per option. The fair
value was estimated using the minimum value method in accordance with SFAS No.
123, "Accounting for Stock-Based Compensation," assuming an expected option life
of 7 years and a risk-free interest rate of 6%.
 
     The Company applies Accounting Principles Board Opinion No. 25 and related
interpretations in accounting for its stock option plan. Accordingly, no
compensation expense has been recognized in the statement of income. If
compensation cost had been determined in accordance with SFAS No. 123, net
income would have decreased approximately $283 during the period ended December
31, 1998.
 
11.  LEASES
 
     The Company leases certain manufacturing equipment, computer equipment and
vehicles under operating leases with lease terms ranging up to 3 years.
Additionally, in connection with the Acquisition, the Company entered into a
capital lease arrangement with Generac Corporation for certain manufacturing
equipment. Property, plant and equipment at December 31, 1998 includes $2,451
for equipment under capital leases, which is net of $165 in accumulated
depreciation. Following is a summary of future minimum payments under
capitalized leases and operating leases that have initial or remaining
non-cancelable lease terms in excess of one year at December 31, 1998:

</TABLE>
 
     The Company sells primarily to large home center retailers. Three customers
accounted for approximately 74% of net sales for the period ended December 31,
1998. All three customers individually comprise more than 10% of the Company's
net sales. Included in accounts receivable at December 31, 1998 and July 9, 1998
are amounts due from these three customers aggregating $29,862 and $34,998,
respectively.
 
13.  COMMITMENTS, CONTINGENCIES AND RELATED PARTY TRANSACTIONS
 
   
     In the normal course of business the Company is involved in certain legal
actions and claims. It is the opinion of management that such litigation and
claims will be resolved without material adverse effect on the Company's
financial position, results of operations or cash flows.
    
 
     In connection with the Acquisition, the Company entered into an OEM engine
supply agreement with Generac Corporation, to supply it with the engine used in
certain of the Company's pressure washers and consumer portable generators. The
engine supply agreement allows for the Company to make minimum purchases of
engines from Generac Corporation in each of the next nine years and gives the
Company the right to increase the amount purchased based upon forecasted
requirements. This agreement is an exclusive arrangement related to such
products subject to the minimum purchase requirements. As the Company maintains
relationships with other major engine suppliers, management believes that the
minimum purchase quantities and unit prices under this agreement will not have
an adverse effect on the Company. Management also considers the provisions of
the engine supply agreement to reflect arms-length terms. For the period ended
December 31, 1998, the Company purchased product approximating $14.4 million
under this agreement. In addition, the Company also purchased other components
from Generac Corporation approximating $6.5 million for the period ended
December 31, 1998. Included in accounts payable are amounts due to Generac
Corporation of approximately $4.7 million at December 31, 1998.
 
   
     In connection with the issuance of the Senior Subordinated Notes, the
Company entered into a registration rights agreement pursuant to which the
Company agreed that it would use its best efforts to file a registration
statement with the Securities and Exchange Commission for the purpose of
exchanging the existing notes for new notes registered under the Securities Act.
Under the registration rights agreement, the Company is subject to liquidated
damages in the form of additional interest at the rate of .50% per annum if
certain deadlines are not met in connection with this filing. The anticipated
impact of the additional interest is not expected to be material.

14.  SEPARATE FINANCIAL INFORMATION OF CO-ISSUERS AND GUARANTOR
 
   
     In connection with the Acquisition, Generac Portable Products, LLC and
GPPW, Inc. co-issued the Notes, and while Generac Portable Products, LLC and
GPPW, Inc. are jointly and severally liable for the obligations under the Notes,
GPPW, Inc. does not conduct any operations, or have any assets of any kind other
than its investment in Generac Portable Products, LLC. The Company has provided
a full and unconditional guarantee of the Notes. However, because the Company
has no operating activities independent of Generac Portable Products, LLC, the
Company's consolidated financial statements are essentially the same as those of
Generac Portable Products, LLC. Separate financial statements of Generac
Portable Products, LLC are not presented because Company management has
determined that they would not be material to investors. Summarized information
for Generac Portable Products, LLC as of December 31, 1998 and for the period
July 10, 1998 through December 31, 1998 is presented below.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders
  of Generac Corporation:
 
     We have audited the accompanying balance sheets of the Portable Products
Division, a Business Unit ("Business Unit") of Generac Corporation ("Company"),
as of July 9, 1998, December 31, 1997 and 1996, and the related statements of
income and cash flows for the six months and nine days ended July 9, 1998 and
the years ended December 31, 1997 and 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     The accompanying financial statements have been prepared from the separate
records maintained by the Business Unit and may not necessarily be indicative of
the conditions that would have existed or the results of operations if the
Business Unit had been operated as an unaffiliated company. Portions of certain
income and expenses represent allocations made from Generac Corporation of items
applicable to the Company as a whole.
 
     In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Portable Products Division, a Business
Unit of Generac Corporation, at July 9, 1998, December 31, 1997 and 1996, and
the results of its operations and its cash flows for the six months and nine
days ended July 9, 1998 and the years ended December 31, 1997 and 1996 in
conformity with generally accepted accounting principles.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The accompanying financial statements include the accounts of the Portable
Products Division located in Jefferson, Wisconsin and its branches in the United

first-out method) or market (replacement cost or estimated net realizable
value).

related products are shipped. A provision for estimated sales returns is
recorded in the period in which the sales are recognized.
 
     RESEARCH AND DEVELOPMENT COSTS -- The Business Unit has an ongoing program

     PRODUCT WARRANTIES -- The Business Unit provides that warranted products
are merchantable and free of defects in workmanship and material generally for a

under selling and service expense for estimated normal warranty costs and, if
applicable, for any significant problems

     FOREIGN CURRENCY TRANSLATION -- The translation of the branch accounts into
U. S. dollars is performed for balance sheet accounts using current exchange
rates in effect at the balance sheet date and for revenue and expense accounts
using an average exchange rate during the period. The gains or (losses)
resulting from such translation are reflected as "cumulative translation
adjustments" in business unit investment. Such adjustments amounted to
$(703,000) through July 9, 1998.
 
     FAIR VALUE OF FINANCIAL INSTRUMENTS -- The Business Unit believes the
carrying amount of its financial instruments (cash and cash equivalents,
accounts receivable and accounts payable) is a reasonable estimate of the fair
value of these instruments.
 
     USE OF ESTIMATES -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
   
2.  BUSINESS UNIT INVESTMENT
    
 
   
     The Business Unit is an operating unit of Generac. The Business Unit
investment balance reflects opening net assets, accumulated earnings for the six
months and nine days ended July 9, 1998 ("1998") and for the years ended
December 31, 1997 ("1997") and 1996 ("1996"), and various activities between the
Business Unit and Generac. Domestic cash management is centralized at Generac
and, as such, the Business Unit's cash funding requirements are met by Generac.
    
 
     The financial statements for 1996 present the results of operations and
cash flows of the carved out Portable Products operations of Generac.
Receivables, inventories, property, plant and equipment, accounts payable,
accrued liabilities, net sales, cost of sales, and selling expenses were
specifically identified for each operation. Liabilities related to employee
compensation were allocated to each operation based upon either employee head
count or payroll. Other expenses relating to service, research and development,
and general and administrative were allocated to each operation based upon
either specific activities or sales levels. Management believes the allocations
are reasonable. Beginning in 1997, the Business Unit operated as a division of
Generac with separate financial reporting.
 
     The financial statements for 1998 and 1997 include allocations by Generac
for certain operating and employee benefit costs incurred on behalf of the
Business Unit. These costs

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
are allocated based on estimates of time and services provided, specifically
identifiable charges, or relevant criteria that establish the Business Unit's
pro rata charge of costs common to all Generac operating units. Allocated
support costs from Generac to the Business Unit during 1998 and 1997 included
manufacturing support of $125,000 and $587,000, service support of $11,000 and
$789,000, research and development support of $21,000 and $410,000, general and
administrative support of $152,000 and $280,000, and human resource and employee
benefits support of $76,000 and $228,000, respectively.
 
     Research and development expenses totaling $131,000, $246,000 and $235,000
were incurred by the Business Unit's United Kingdom branch during 1998, 1997 and
1996, respectively, on behalf of Generac and charged to Generac.
 
     The Business Unit and Generac supply each other with certain inventories.
Total inventories transferred during 1998, 1997 and 1996 were $7,855,000,
$9,541,000 and $11,374,000, respectively, from Generac to the Business Unit and
$350,000, $1,330,000 and $0, respectively, from the Business Unit to Generac.
Commencing February 1, 1998, certain production was transferred from the
Business Unit to Generac. During the five months and nine days ended July 9,
1998, the Business Unit purchased $12,223,000 of inventories related to such
transferred production. At July 9, 1998, such inventory represented
approximately $2,673,000 including profit of approximately $508,000. All other
inventory is transferred at cost.
 
     The Business Unit is also charged a portion of Generac's interest expense
based upon levels of Business Unit investment. This interest charge aggregated
$1,354,000, $1,999,000 and $2,237,000 during 1998, 1997 and 1996, respectively.
 
     Management believes the allocations and activities between the Business
Unit and Generac are reasonable under the circumstances; however, they may not
be indicative of amounts that would be required to be incurred if the Business
Unit operated on a stand-alone basis.

     Generac has noncontributory pension plans (salaried and hourly) covering
substantially all of its employees including the employees of the Business Unit.

participants' defined final average monthly compensation. The benefits under the
hourly plan are based on a unit amount at the date of termination multiplied by
the participants' credited service. Generac's funding policy for these plans is
to contribute amounts at least equal to the minimum annual amount required by
applicable regulations. Total pension expense allocated to the Business Unit for
the six months and nine days ended July 9, 1998 and the years ended December 31,
1997 and 1996 was $231,000, $293,000 and $255,000, respectively.

Business Unit and at July 9, 1998, approximately $182,000 of deferred
compensation was included in accrued employee benefits. Deferred compensation
expense charged to operations was $18,000, $40,000 and $23,000, for the six

                                                             $2,797,000
                                                             ==========
</TABLE>
 
     Total rent expense for the six months and nine days ended July 9, 1998 and
the years ended December 31, 1997 and 1996 was approximately $476,000, $462,000
and $100,000, respectively.
 
     Certain manufacturing equipment with an original cost of $3,178,000 is
leased under a five-year master lease arrangement and accounts for $353,000 and
$385,000 of total rental expense for the six months and nine days ended July 9,
1998 and for the year ended December 31, 1997, respectively; $673,000 of future
annual commitments through 2001; and all of the year 2002 commitments. At the
end of the lease term, Generac has the option to purchase the equipment at a
purchase price equal to the then fair market value which shall not be less than
15% nor more than 25% of the original equipment cost.

from these two customers aggregating $6,608,000.

18% and 20% of the total Business Unit's assets as of July 9, 1998, December 31,

accounted for approximately 8%, 8% and 10% of net sales for the six months and

respectively.

legal actions and claims. It is the opinion of management that such litigation
and claims will be resolved without material effect on the Business Unit's
financial position or results of operations.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     In general, the Wisconsin Business Corporation Law provides that a
corporation shall indemnify directors and officers for all reasonable expenses
incurred in connection with the successful defense of actions arising in
connection with their service as directors and officers of the corporation. In
other cases, the Wisconsin Business Corporation Law provides that the
corporation shall indemnify a director or officer against liability unless the
director or officer breached or failed to perform a duty owed to the corporation
and such breach or failure meets certain specified criteria constituting, in
general, some act of misconduct. In addition, the corporation may reimburse a
director or officer for his expenses in defending against actions as they are
incurred upon the director's or officer's written request accompanied by a
written affirmation of his good faith belief that he has not breached or failed
to perform his duties to the corporation and a written undertaking to repay
amounts advanced if it is ultimately determined that indemnification is not
required under the Wisconsin Business Corporation Law. A court of law may order
that the corporation provide indemnification to a director or officer if it
finds that the director or officer is entitled thereto under the applicable
statutory provision or is fairly and reasonably entitled thereto in view of all
the relevant circumstances, whether or not such indemnification is required
under the applicable statutory provision.
 
     The Wisconsin Business Corporation Law specifies various procedures
pursuant to which a director or officer may establish his right to
indemnification.
 
     Provided that it is not determined by or on behalf of the corporation that
the director or officer breached or failed to perform a duty owed to the
corporation and such breach or failure meets certain specified criteria
constituting, in general, some act of misconduct, a Wisconsin corporation may
provide additional rights to indemnification under its articles of incorporation
or by-laws, by vote, by agreement or by resolution.
 
     GPPW's Articles of Incorporation provide for indemnification and
advancement of expenses of directors and officers to the fullest extent
permitted by the Wisconsin Business Corporation Law. The indemnification
provided by GPPW's Articles of Incorporation is not deemed to be exclusive of
any other rights to which an officer or director may be entitled under any
by-law, vote of shareholders or disinterested directors or otherwise.
 
     Section 18-108 of the Delaware Limited Liability Company Act grants a
Delaware limited liability company the power, subject to the standards and
restrictions, if any, as are set forth in its limited liability company
agreement, to indemnify any member or manager or other person from and against
any and all claims and demands whatsoever.
 
   
     Pursuant to Article VIII of the Limited Liability Company Agreement of
Generac Portable Products, LLC (the "LLC Agreement"), Generac Portable Products,
LLC will indemnify any person who was or is a party or is threatened to be made
a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of Generac Portable Products, LLC) by reason of the fact that
such person is or was a director or officer of Generac Portable Products, LLC,
or is or was serving, at Generac Portable Products, LLC's request, in a similar
capacity with another enterprise. Generac Portable Products, LLC will indemnify
such officers and directors in an action by or in the right of Generac Portable
Products, LLC to procure a judgment in its favor under the same conditions,
    
 
                                      II-1
<PAGE>   151
 
   
except that no indemnification is permitted without judicial approval if the
officer or director is adjudged to be liable to Generac Portable Products, LLC.
Where an officer or director is successful on the merits or otherwise in the
defense of any action referred to above, Generac Portable Products, LLC must
indemnify him or her against the expenses (including attorneys' fees) which he
or she actually and reasonably incurred in connection therewith.
    
 
   
     Generac Portable Products, LLC will, in connection with his or her
appearance as a witness or other participation in a proceeding, pay the expenses
actually or reasonably incurred or anticipated by any officer or director
participating in such proceeding, provided that the director or officer
undertakes to repay such amount if it shall ultimately be determined that he or
she is not entitled to be indemnified by Generac Portable Products, LLC as
authorized by Article VIII of the LLC Agreement.
    
 
     The indemnification provided by the LLC Agreement is not deemed to be
exclusive of any other rights to which an officer or director may be entitled
under any law, agreement, vote or otherwise.
 
   
     Generac Portable Products, LLC may grant indemnification rights to other
employees or agents of, or other persons serving, Generac Portable Products,
LLC. Generac Portable Products, LLC is also permitted to purchase directors' and
officers' liability insurance. Article VIII of the LLC Agreement also provides
that Generac Portable Products, LLC will indemnify its officers and directors to
the fullest extent permitted by applicable law in effect from time to time.
    
 
     The foregoing statements are subject to the detailed provisions of Article
VIII of the LLC Agreement.

     pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
     of 1934 (and, where applicable, each filing of an employee benefit plan's
     annual report pursuant to Section 15(d) of the Securities Exchange Act of
     1934) that is incorporated by reference in the registration statement shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.
    
 
          (2) That, insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the Registrants pursuant to the foregoing
     provisions, or otherwise, the Registrants 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 and is,
     therefore, unenforceable. In the event that a claim for indemnification
     against such liabilities (other than the payment by any Registrant of
     expenses incurred or paid by a director, officer or controlling person of
     such Registrant in the successful defense of any action, suit or
     proceeding) is asserted by such director, officer or controlling person in
     connection with the securities being registered, the Registrants will,
     unless in the opinion of their counsel the matter has been settled by
     controlling precedent, submit to a court of appropriate jurisdiction the
     question whether such indemnification by it is against public policy as
     expressed in the Securities Act of 1933 and will be governed by the final
     adjudication of such issue.
 
   
          (3) To respond for requests for information that is incorporated by
     reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this
     Form, within one business day of receipt of such request, and to send the
     incorporated documents by first class mail or other equally prompt means.
     This includes information contained in documents filed subsequent to the
     effective date of the registration statement through the date of responding
     to the request.
    
 
   
          (4) To supply by means of a post-effective amendment all information
     concerning a transaction, and the company being acquired or involved
     therein, that was not the subject of and included in the registration
     statement when it became effective.
    
 
   
          (5) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
    
 
   
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
    
 
   
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to
    
 
                                      II-4
<PAGE>   154
 
   
        Rule 424(b) if, in the aggregate, the changes in volume and price
        represent no more than 20 percent change in the maximum aggregate
        offering price set forth in the "Calculation of Registration Fee" table
        in the effective registration statement.
    
 
   
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;
    
 
   
          (6) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
    
 
   
          (7) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

Jefferson, Wisconsin 53549

Ladies and Gentlemen:

         We have acted as counsel to Generac Portable Products, Inc., a Delaware
corporation ("Holdings"), Generac Portable Products, LLC, a Delaware limited
liability company (the "Company"), and GPPW, Inc., a Wisconsin corporation
("GPPW" and, together with Holdings and the Company, the "Registrants"), in
connection with the registration, pursuant to a Registration Statement on Form
S-4 (the "Registration Statement") filed today by the Registrants under the
Securities Act of 1933, as amended (the "Securities Act"), of (i) the offer to
exchange the 11 1/4% Senior Subordinated Notes due 2006 (the "New Notes" ) of
the Company and GPPW for all outstanding 11 1/4% Senior Subordinated Notes due
2006 (the "Old Notes" and, together with the New Notes, the "Notes") of the
Company and GPPW that were issued on July 2, 1998 in a transaction exempt from
the registration requirements of the Securities Act, and (ii) issuance of the
irrevocable and unconditional guarantee on a senior subordinated basis by
Holdings of the obligations of the Company and GPPW under the New Notes (the

                          OEM ENGINE SUPPLY AGREEMENT
 
   
     THIS EXCLUSIVE SUPPLY AGREEMENT (the "Agreement") is made and entered into
on the 9th day of July, 1998, by and between GENERAC CORPORATION, a Wisconsin
corporation with its principal office and place of business in Waukesha,
Wisconsin ("Seller") and GENERAC PORTABLE PRODUCTS, INC. (F/K/A GPPC, INC.), a
Delaware corporation ("Buyer"). This Agreement shall be binding as of the date
written above but for purposes of computing time periods and anniversary dates,
the effective date shall be considered to be July 9, 1998.
    
 
                                    RECITALS
 
     A.  As a result of its purchase from Seller of Seller's portable products
division, Buyer is now engaged in the marketing, manufacture and sale of
welders, pressure washers, Consumer Portable Generators and other similar
portable equipment. For the purpose of this Agreement "Consumer Portable
Generators" are defined as; air-cooled generators currently of the type in
production at the portable products division at time of signing the Agreement.
 
     B.  Seller is engaged in the business of manufacturing its GN series single
cylinder engines, in particular, models GN-191, GN-220, GN-360 and GN-410 which
are suitable for powering such equipment (the "Engines").
 
     C.  In connection with Buyer's purchase of Seller's portable products
division, Buyer desires that Seller manufacture the Engines requested by Buyer
from time to time according to Seller's established specifications for the
Engines (the "Specifications") and Seller has adequate facilities, expertise and
personnel to manufacture the Engines according to the Specifications.
 
     D.  Buyer desires to purchase the Engines from Seller, and Seller desires
to manufacture and sell the Engines to Buyer on the terms and subject to the
conditions set forth below.
 
                                   AGREEMENTS
 
     In consideration of the above recitals and the mutual covenants and
valuable consideration contained herein, the parties agree as follows:
 
     1.  SUPPLY OF PRODUCTS.
 
   
          (a) SALE AND PURCHASE OF ENGINES.  Seller shall manufacture and sell
     to Buyer and Buyer shall purchase from Seller the Engines during the term
     of this Agreement pursuant to the terms and conditions set forth herein.
     Buyer shall purchase a minimum of [          ] Engines during each annual
     period of this Agreement (the "Minimum Purchase Obligation"). In addition
     to the Minimum Purchase Obligation, in each annual period following the
     fifth annual period of this Agreement, Buyer shall purchase from Seller an
     aggregate number of Engines at least equal to 25% of the total number of
     engines purchased by Buyer during such period (the "25% Requirement"),
     provided, however that during such annual periods Buyer shall nevertheless
     not purchase less than the Minimum Purchase Obligation. For purposes of
     determining whether Buyer has satisfied the 25% Requirement in any annual
     period following the fifth annual period of this Agreement, Seller shall
     have the right to select an independent accounting firm (the "Accounting
     Firm"), reasonably accept-
    
<PAGE>   2
 
     able to Buyer, to perform an audit of Buyer's total engine purchases for
     the period in question. If Seller and Buyer cannot agree upon an
     independent accounting firm to act as the Accounting Firm, each of Buyer
     and Seller shall select an independent accounting firm and the two firms so
     selected shall select a third independent accounting firm which shall be
     the Accounting Firm. The Accounting Firm shall conduct an audit of Buyer's
     total engine purchases for the annual period in question and shall
     determine whether the 25% Requirement has been satisfied for the applicable
     period. The conclusion of the Accounting Firm shall be final and binding
     upon Buyer and Seller. Buyer agrees to cooperate fully with the Accounting
     Firm in connection with conducting any audits pursuant to this section,
     including, without limitation, making available to the Accounting Firm such
     books and records of Buyer as the Accounting Firm may reasonably request in
     connection with its audit. If Buyer desires to purchase more than the
     Minimum Purchase Obligation, or, after the fifth annual period hereof, more
     than the 25% Requirement (if greater than the Minimum Purchase Requirement)
     during any annual period of this Agreement, Seller shall, subject to
     section 3(c) of this Agreement, use its reasonable efforts to manufacture
     and sell to Buyer such additional quantity of the Engines as Buyer may
     request.
 
          (b) EXCLUSIVE SUPPLY REQUIREMENT.  As long as Buyer satisfies the
     Minimum Purchase Obligation and, after the fifth annual period, the 25%
     Requirement (if greater than the Minimum Purchase Obligation), Seller
     agrees not to sell Engines to any other original equipment manufacturer
     ("OEM") for purposes of incorporation into welders, pressure washers,
     Consumer Portable Generators or other products approved by Seller (the
     "Exclusive Supply Requirement"). If Buyer does not comply with the Minimum
     Purchase Obligation or, after the fifth annual period, the 25% Requirement
     (if greater than the Minimum Purchase Obligation), the Exclusive Supply
     Requirement shall be void for the remainder of the term of the Agreement
     unless (i) the Buyer purchased at least 80% of the Minimum Purchase
     Obligation or, after the fifth annual period, the 25% Requirement (if
     greater than the Minimum Purchase Obligation) during the period in question
     and (ii) during the immediately following annual period Buyer purchases the
     Minimum Purchase Obligation or, after the fifth annual period, the 25%
     Requirement (if greater than the Minimum Purchase Obligation) plus the
     number of Engines by which it failed to meet the Minimum Purchase
     Obligation or, after the fifth annual period, the 25% Requirement (if
     greater than the Minimum Purchase Obligation) during the preceding annual
     period. If Buyer fails to meet the Minimum Purchase Obligation or, after
     the fifth annual period, the 25% Requirement (if greater than the Minimum
     Purchase Obligation) during any annual period and, if applicable, fails to
     correct the shortfall during the immediately following annual period,
     Seller's sole remedy shall be voidance of the Exclusive Supply Requirement
     as provided in this section 1(b), provided, this sentence shall not be
     interpreted to restrict Seller's ability to increase gross margin pursuant
     to section 4(a)(i).
 
          (c) ADDITIONAL REQUIREMENTS FOR WELDERS.  Seller and Buyer recognize
     that, heretofore, sales of welders by Seller have been nominal and that
     Buyer will undertake to substantially increase the sale of welders. Seller
     and Buyer also recognize that in the event Buyer is unable to do so, Seller
     should be availed of the opportunity to sell Engines to other manufacturers
     of welders. Commencing on the first anniversary of this Agreement and
     within thirty (30) days following the end of each calendar quarter after
     such first anniversary, Buyer shall provide to Seller a written report as
     to the number of Engines shipped with welders during such calendar quarter.
     If during any
 
                                        2
<PAGE>   3
 
   
     consecutive four (4) calendar quarters covered by such reports, Buyer ships
     fewer than [     ] welders equipped with one of the Engines, Seller may
     sell Engines to any other OEM of welders.
    
 
          (d) RETAINED RIGHTS OF SELLER.  Notwithstanding the exclusivity
     requirements in section 1(b) above, Seller shall have the right to sell
     engines through its own Service Distributor and Dealer Network for any
     application based on repower and service promulgated prices. Buyer
     acknowledges that the provisions of this paragraph may or will benefit
     Buyer in that Seller's service network, which services Buyer's customers,
     is thereby further supported. Nothing in this Agreement will be construed
     to prevent Seller from selling its engines, including the Engines, to any
     other purchaser, original equipment manufacturer or otherwise, and at any
     price it elects, so long as such engines and Engines are not for use with
     welders, pressure washers or Consumer Portable Generators. Seller retains
     the right to use and sell GN engines to other air-cooled generator
     applications, including, but not limited to, R.V., Industrial Mobile,
     Telecom, Home Stand-By or any other type of residential, commercial or
     industrial application.
 
     2.  TERM OF AGREEMENT.  Subject to the provisions for termination set forth
elsewhere in this Agreement, this Agreement shall commence on the date first
written above and continue for 95 years (the "Initial Term"). After completion
of the Initial Term, this Agreement shall automatically renew for consecutive 3
year periods ("Renewal Term") unless either party gives written notice of its
intent to terminate this Agreement to the other party at least 6 months prior to
the expiration of the Initial Term or any Renewal Term. Notwithstanding the
foregoing, in the event of a sale of Seller's assets or Seller's stock as
described in section 12 below (whether during the Initial Term or any Renewal
Term), upon the closing date of such sale the remaining term of this Agreement
shall be the longer of 5 years or the remainder of the Initial Term 5 years
subject to 3 year renewal terms as described in the second sentence of this
section.
 
     3.  PRODUCT ORDERS.
 
          (a) PURCHASE ORDERS.  Purchase orders will be issued by Buyer on the
     first business day of each month specifying Buyer's requirements for the
     fourth month following the month in which the purchase order is issued. In
     the event Buyer desires to issue a purchase order for a quantity of Engines
     20% greater than Buyer's average monthly orders for the previous twelve
     (12) months, Buyer must provide Seller with written notice of such order no
     less than six months prior to the start of shipment. All purchase orders
     for Engines to be manufactured and delivered shall be firm and may not be
     canceled or modified by Buyer without the written permission of Seller;
     provided, however, that Purchase orders may be modified by Buyer to provide
     for a later delivery date (not in excess of 60 days) upon notice to Seller
     at least 60 days prior to the requested delivery date.
 
          Purchase orders issued by the Buyer to the Seller shall specify the
     Engines being ordered in some minimum package quantity as specified by
     Seller, the required delivery dates, and the address to which Seller's
     invoice shall be sent. Any provision, term or condition set forth on
     Buyer's purchase order or on any acknowledgment, invoice or other document
     or communication provided by Buyer which is inconsistent with the terms of
     this Agreement, or is not addressed herein, is void and of no effect.
 
          (b) SELLER'S PURCHASE ORDER ACKNOWLEDGMENT.  Seller's purchase order
     acknowledgment shall reflect the Buyer's purchase order number. A separate
     purchase order
 
                                        3
<PAGE>   4
 
     acknowledgment shall be rendered for each purchase order and shall be
     transmitted by Seller to the address specified on the purchase order. Each
     purchase order acknowledgment rendered by Seller shall separately identify
     the Engines by model number, quantities thereof, unit prices, and total
     amount due for such Engines. Applicable sales or use taxes shall also be
     reflected.
 
          (c) FORECASTS.  Prior to the beginning of each calendar quarter, Buyer
     shall provide seller with a rolling written forecast of its estimated
     requirements for the Engines in each of the next four (4) calendar quarters
     (the "Quarterly Forecast"). Each Quarterly Forecast shall contain an update
     of the immediately preceding Quarterly Forecast with respect to the
     quarters referred to in such preceding Quarterly Forecast.
 
          In addition to the Quarterly Forecasts, if Buyer intends to purchase
     in any future four (4) calendar quarter period (the "Expansion Period")
     more than 120% of the number of Engines actually purchased in the four (4)
     calendar quarters just ended, Buyer shall provide Seller with Buyer's
     estimated requirements for the Engines in the Expansion Period a minimum of
     six months prior to the start of the Expansion Period (the "Expansion
     Forecast").
 
          Notwithstanding anything to the contrary in this Agreement, Seller
     shall have no obligation during the applicable period to manufacture and
     sell to Buyer any number of Engines greater than the Quarterly Forecast or
     the Expansion Forecast as applicable. Buyer shall use its best efforts to
     ensure that firm orders under section 3(a) of this Agreement conform to the
     estimates in the latest forecast.
 
     4.  PRICES AND PAYMENT TERMS.
 
          (a) ENGINE PRICES.
 
             (i) Buyer shall pay Seller for the Engines in accordance with the
        prices set forth in Schedule A which are subject to modification from
        time to time in accordance with the terms of this Agreement. At least 30
        days prior to each annual anniversary of this Agreement, the parties
        shall negotiate in good faith to determine the price for Engines for the
        upcoming year based on the expected cost of raw materials, freight,
        insurance, direct labor, appropriate indirect manufacturing operating
        expenses and overhead (the "Costs of Production"), plus a gross margin
        of 20%. Following the fifth annual period of this Agreement, Seller
        shall have the continuing right to increase the gross margin up to a
        total of 23%. The Seller shall not have the right to increase the gross
        margin pursuant to the immediately preceding sentence if Seller is in
        violation of the Exclusive Supply Requirement at the time of such
        increase unless the Exclusive Supply Requirement has been voided in
        accordance with section 1(b) in which case Seller may exercise its right
        under the immediately preceding sentence. Any agreed upon change to the
        price for the Engines shall be applied to Engines purchased during the
        following twelve-month period.
 
             The Costs of Production shall be determined by Seller in its sole
        discretion. Buyer shall be entitled, at the time of each regularly
        scheduled price renegotiation, to review (subject to the confidentiality
        provisions of this Agreement) Seller's records that directly pertain to
        Seller's calculation of the Costs of Production. If Buyer does not agree
        with Seller's calculation of the Costs of Production, Buyer's sole
        remedy shall be to purchase engines from
 
                                        4
<PAGE>   5
 
        another supplier. All prices for Engines supplied under this Agreement
        are F.O.B. Seller's plant in Whitewater, Wisconsin.
 
             (ii) On February 15 and August 15 of each year during the term of
        this Agreement, if Seller's Costs of Production have increased or
        decreased during the previous July through December or January through
        June period, respectively (the "Production Period") due to (a) changes
        in the price of aluminum and/or (b) changes in the price of foreign
        components for the Engines caused by changes in currency rates, Seller
        shall pay to Buyer (in the case of a decrease in such Costs of
        Production) or Buyer shall pay to Seller (in the case of an increase in
        such Costs of Production) an amount calculated in accordance with the
        formula set forth in Schedule C.
 
             (iii) Seller agrees to use commercially reasonable efforts to work
        with the lowest cost suppliers of the materials and services used
        directly in connection with manufacturing the Engines in order to keep
        the Costs of Production at reasonable levels. Seller agrees to
        investigate any potential suppliers suggested by Buyer. Seller retains
        the right to reject suppliers that do not provide materials and/or
        services, as applicable, of the quality and performance level which, by
        Seller's sole determination, is at least at the same level of quality
        and performance provided by Seller's existing suppliers of such
        materials and/or services.
 
          (b) NON-RECURRING ENGINEERING CHARGE.  Buyer agrees to pay Seller a
     non-recurring engineering fee with respect to Seller's preparation for
     manufacture of the specific engine components exclusive to Buyer and for
     the acquisition of certain tooling, equipment and fixtures in connection
     with the manufacturing of such components. Upon Buyer's request, Seller
     shall provide Buyer with the amount of such fee, reasonable detail of the
     fee and the payment terms of such fee (the "Engineering Proposal"). Buyer
     shall own title to certain tooling, equipment and fixtures detailed in the
     Engineering Proposal and for which the payment of associated non-recurring
     engineering fees has been received.
 
          (c) PAYMENT TERMS.  The terms of payment of Seller's invoices shall be
     net 30 days from Seller's invoice date. If Buyer disputes any invoice in
     good faith, in whole or in part, Buyer shall promptly notify the Seller in
     writing and shall set forth the basis for such dispute. The parties will
     then use their best efforts to resolve the dispute expeditiously. Any such
     dispute not resolved within 30 days may be submitted to binding arbitration
     in accordance with section 13 of this Agreement. Any invoice balance which
     remains unpaid after 30 days shall bear interest at the rate of 1.5% per
     month until paid.
 
          (d) SUSPENSION OR TERMINATION FOR FAILURE TO PAY INVOICES WHEN
     DUE.  In the event that Buyer fails to pay any invoice, other than amounts
     which are in good faith dispute, when due, Seller may, at its option,
     immediately suspend its performance under the Agreement five days after
     providing written notice to Buyer of the overdue amount if such amounts are
     not paid within the five day period. Seller shall be under no obligation to
     resume performance until all overdue amounts, other than amounts in good
     faith dispute, are paid. Seller may, at its option, immediately terminate
     this contract if Buyer fails to pay any such amounts due which are not in
     good faith dispute within 15 days of the written notice of the overdue
     amount.

     5.  TESTING, DELIVERY, USE, PRIVATE LABELS AND SERVICE AND PARTS.
 
          (a) SELLER TESTING.  All Engines shall be inspected and tested by
     Seller for conformity to the Specifications prior to shipment to the Buyer.
 
          (b) DELIVERY.  All Engines manufactured by Seller under this Agreement
     shall be delivered F.O.B. Seller's plant, Whitewater, Wisconsin, and upon
     such delivery to carrier, title and risk of loss shall pass to Buyer.
 
          (c) RISK OF RESALE AND NO INDEPENDENT RIGHT TO RESELL.  Risk of resale
     of the Engines shall be with the Buyer. Under no circumstances shall Seller
     assume any liability whatever in the event that Buyer is unable to resell
     the Engines, and Buyer shall have no right to return the Engines to Seller
     under such circumstances. Buyer shall resell Engines solely as components
     in its welders, pressure washers, Consumer Portable Generators and other
     products approved by Seller. Buyer shall not, and shall not have the right
     to, resell Engines independently of its welders, pressure washers, Consumer
     Portable Generators or other products approved by Seller.
 
          (d) APPROVAL OF APPLICATIONS.  Seller shall have the right to approve
     all applications and uses of the Engines and Buyer shall request and
     receive such approval in writing prior to any application or use of the
     Engines not already approved hereby. Seller hereby approves the application
     and use of the Engines as components in Buyer's existing product lines of
     welders, pressure washers and Consumer Portable Generators to the extent
     the Engines are used therein as of the date hereof.
 
          (e) PRIVATE LABELS.  Buyer may not use any private label on the
     Engines without the written consent of Seller. Seller hereby consents to
     the private label "Craftsman." Approved private labels may only be used in
     connection with the incorporation of Engines as components in Buyer's
     welders, pressure washers, Consumer Portable Generators and other products
     approved by Seller.
 
          (f) SERVICE AND PARTS.  Seller shall, to the extent required by this
     Agreement and to the extent requested by Buyer and agreed to by Seller,
     provide repair services for the Engines and Buyer shall utilize Seller for
     the performance of such repair services. Additionally, Seller shall sell to
     Buyer and Buyer shall purchase from Seller spare and replacement parts for
     the Engines, in the quantities which Buyer may request and which Seller may
     agree to sell, at the price at which Seller sells such spare and
     replacement parts to its master parts distributors, which may be modified
     by Seller from time to time.
 
     6.  WARRANTIES.
 
          (a) LIMITED WARRANTY.  The Engines will be subject to Seller's
     standard limited warranty for the Engines which is set forth on Schedule B
     (the "Limited Warranty"). Seller retains the right to modify the Limited
     Warranty at any time and from time to time. SELLER MAKES NO OTHER
     WARRANTIES OR REPRESENTATIONS, EITHER EXPRESSED OR IMPLIED, WITH RESPECT TO
     THE ENGINES, INCLUDING THEIR DESIGN, QUALITY, PERFORMANCE, MERCHANTABILITY,
     OR FITNESS FOR A PARTICULAR PURPOSE.
 
          (b) WARRANTY EXCLUSIONS.  Seller makes no warranty of any kind with
     respect to:
 
             (i) Repairs for Engines necessitated by normal wear and tear,
        damage in transit or accident, through abuse, misuse or negligence of
        Buyer or its
 
                                        6
<PAGE>   7
 
        customers, or by failure of any of those persons to maintain or use the
        Engines in accordance with Seller's written instructions; or
 
             (ii) Engines that have been modified in any manner after shipment
        by Seller.
 
          (c) RETURN AUTHORIZATION.  Engines warranted by Seller shall be
     repaired or replaced at Seller's option and expense upon presentation of
     evidence that demonstrates to Seller's reasonable satisfaction a breach of
     the Limited Warranty. Prior to return of any Engine to Seller, Buyer shall
     obtain a return authorization from Seller and comply with Seller's return
     authorization procedures in force at the time of the return. Seller shall
     have no obligation to repair or replace Engines returned without a return
     authorization.
 
          (d) LIMITATION OF REMEDIES.  Buyer's exclusive remedy for any defect
     in the Engines or breach of Seller's warranty under section 6(a) of this
     Agreement is, at Seller's option, either refund of the price paid by Buyer
     for the defective Engines, repair of the defective Engines sufficient to
     cause them to meet the Specifications or replacement of the defective
     Engines with equivalent Engines that meet the appropriate Specifications.
 
          IN NO EVENT SHALL SELLER BE LIABLE FOR ANY INDIRECT, SPECIAL,
     INCIDENTAL, CONSEQUENTIAL OR OTHER DAMAGES, INCLUDING ANY LOST PROFITS OF
     BUYER, IN CONNECTION WITH SELLER'S BREACH OF THIS AGREEMENT IN ANY WAY,
     INCLUDING, BUT NOT LIMITED TO, THE FAILURE OF THE ENGINES TO MEET THE
     SPECIFICATIONS OR SELLER'S FAILURE TO DELIVER THE ENGINES WHEN DUE OR AT
     ALL.
 
          The parties acknowledge that the limitation of damages contained in
     this paragraph is a separate item of their agreement. The parties
     acknowledge their intent that this limitation of damages shall be severable
     from the limited warranty and shall be enforceable even if the limitations
     in the limited warranty are held to be unenforceable.
 
     7.  CONFIDENTIAL AND PROPRIETARY INFORMATION.
 
          (a) OWNERSHIP OF INFORMATION.  Buyer acknowledges that all information
     disclosed to it by Seller pursuant to this Agreement, including all
     information pertaining to the design of and the manufacturing process for
     the Engines and all information pertaining to the conduct of Seller's
     business and affairs, shall, at all times, both during and after the
     termination of this Agreement, however occurring, remain the exclusive
     property of Seller and that Buyer shall not acquire any proprietary
     interest in such information.
 
          Seller acknowledges that all information disclosed to it by Buyer
     pursuant to this Agreement, including all information pertaining to the
     conduct of Buyer's business and affairs, shall, at all times, both during
     and after the termination of this Agreement, however occurring, remain the
     exclusive property of Buyer and that Seller shall not acquire any
     proprietary interest in such information.
 
          (b) ACCESS TO CONFIDENTIAL INFORMATION.  Neither party shall, directly
     or indirectly, disclose, or permit anyone to disclose, any Confidential
     Information disclosed or made available by the other party, and shall
     carefully guard and keep secret all such Confidential Information. Neither
     party shall, at any time, allow anyone other
 
                                        7
<PAGE>   8
 
     than the other party hereto, or those authorized by the other party, to
     have access to or use any Confidential Information disclosed or made
     available by the other party. Each party shall use all reasonable efforts
     to protect the proprietary nature of any and all Confidential Information
     of the other.
 
          Except as expressly provided otherwise in this Agreement, neither
     party shall copy, modify, transcribe, store, sell, lease or otherwise
     transfer or distribute any Confidential Information of the other in whole
     or in part without prior authorization in writing from the other party.
     Both parties shall use the Confidential Information only during the term of
     this Agreement and solely for the purpose of carrying out the intent of
     this Agreement.
 
          For purposes of this Agreement, the term "Confidential Information"
     includes, without limitation, a party's techniques, processes, procedures,
     operations and other proprietary information relating to research and
     development, design, manufacturing, operations, marketing and finances.
     Upon termination of this Agreement, however occurring, both parties shall
     surrender to the other party all documents including, but not limited to,
     plans, specifications, literature, samples, documents and other tangible
     things, relating to Confidential Information disclosed or made available by
     the other party and all supplies which are the property of the other party.
 
          (c) LIABILITY FOR DISCLOSURE.  Neither party shall be liable for
     disclosure to others of Confidential Information disclosed or made
     available to it by the other party if the information: (i) can be
     demonstrated by contemporaneous written records to have been in the other
     party's possession or available to the other party prior to the receipt of
     same from Buyer or Seller as the case may be; (ii) can be demonstrated by
     clear and convincing evidence to have been received from a third party
     having no obligation to hold the same in confidence; (iii) can be
     demonstrated by clear and convincing evidence to have been generally known
     or generally available to the public prior to the date of the disclosure;
     (iv) becomes generally known or generally available to the public through
     no act or failure to act on the part of either party or its affiliates; or
     (v) is required by a valid order of a court of law to be disclosed.
 
          If any Confidential Information of a party is required by law to be
     disclosed by the other party hereto (as contemplated by section 7(c)(iv)),
     the disclosing party shall provide the nondisclosing party with prompt
     notice of such disclosure and take such legally available steps as may be
     necessary to resist or narrow such request and/or to procure a court order
     stipulating that the Confidential Information required to be disclosed
     shall be used solely for the purposes for which the court order was issued.
 
          (d) NO GRANT OF LICENSE.  No rights or obligations other than those
     expressly stated shall be implied from this Agreement. In particular, no
     license or other right is hereby granted, either express or implied, to one
     party by the other party (i) with respect to the other party's Confidential
     Information or (ii) under any patent, patent application, copyright,
     trademark, or other proprietary right or intellectual property right now or
     hereafter controlled by the other party.
 
          (e) Buyer understands and agrees that the Engines embody design and
     manufacture information including, but not limited to, design or production
     concepts, methods, materials, structures, assemblies or similar information
     which is proprietary to Seller (the "Design Information"). Buyer shall not
     reverse engineer or disassemble the Engines and shall not use, nor permit
     any third party to use, the Design
 
                                        8
<PAGE>   9
 
     Information for any purpose other than those necessary to further the
     transactions contemplated by this Agreement. Under no circumstances shall
     the Buyer have the right to use the Design Information to design or
     manufacture any product, or assist any third party in manufacturing any
     product, which competes with the Engines.
 
          (f) SPECIFIC PERFORMANCE.  The Parties agree that breach of this
     section 7 by either party would cause irreparable damage to the other party
     and that monetary damages alone would not provide the injured party with an
     adequate remedy for such breach. Therefore, if any controversy arises
     concerning the rights or obligations of either party under this section 7,
     such rights or obligations may be specifically enforced by an injunction
     order issued by a court of competent jurisdiction. Such remedy, however,
     shall be in addition to any other remedy to which the injured party may be
     entitled.
 
     8.  INDEMNIFICATION.
 
          (a) BREACH OF THIS AGREEMENT.  Subject to the limitations set forth in
     section 6(d) of this Agreement, each party agrees to indemnify and hold the
     other party, its affiliates, shareholders, directors, officers, employees,
     customers, successors and assigns harmless against all liabilities, claims,
     costs, damages, losses and expenses, including reasonable legal fees and
     related costs, which the indemnified party incurs by reason of the
     defaulting party's failure to perform its obligations under this Agreement.
 
          If a claim, demand or suit is presented or filed against the
     nondefaulting party and indemnification by the nondefaulting party is
     sought pursuant to this provision, the nondefaulting party shall give
     prompt notice to the defaulting party and provide reasonable assistance to
     and cooperation with the defaulting party, at the defaulting party's cost,
     in the settlement or defense of the claim, demand or suit. The right of
     indemnification shall be extinguished if the nondefaulting party fails to
     give notice of the claim, demand or suit, or settles the same without the
     written consent of the defaulting party.
 
          (b) INDEMNIFICATION BY BUYER.  Buyer agrees to indemnify and hold
     harmless Seller, its officers, employees and agents, from and against all
     loss, damages, liability and expense incurred by reason of any claims,
     actions, suits or governmental investigations or proceedings including, but
     not limited to, product liability claims, brought against or involving them
     or any of them, which relate to or arise out of the manufacture of the
     Engines by Seller for the Buyer. Provided, however, that Buyer shall not be
     obligated to indemnify Seller for any claim which arises out of Seller's
     failure to comply with the limited warranty for the Engines described in
     section 6 above or failure to manufacture the Engines in compliance with
     the Specifications.
 
          (c) PRODUCT LIABILITY.
 
             (i) INSURANCE.  During the term of this Agreement, and for a period
        of three years thereafter, each party will at its own expense purchase
        (if it has not already purchased) and maintain general product liability
        insurance, naming the other party as an additional insured. The coverage
        shall have limits of liability of no less than $5 million and shall be
        placed with an insurance carrier having a Best's rating of no less than
        "A". Each party shall provide a copy of the insurance policy to the
        other party upon the other party's request.
 
                                        9
<PAGE>   10
 
     9.  TERMINATION.  In addition to any other provision of this Agreement
which grants a right of termination, the following shall also constitute bases
for termination:
 
          (a) A material default in the performance of an obligation under this
     Agreement, provided such default continues for more than [60][120] days
     after written notice is provided by the nondefaulting party.
 
          (b) If either party becomes the subject of a voluntary bankruptcy or
     insolvency proceeding; if such proceeding is involuntary, then the right of
     termination shall exist only if such proceeding has continued unstayed for
     a period of 60 consecutive days after filing.
 
          Upon the expiration or termination of this Agreement as set forth
     above, Seller will complete Engines on order at the date of termination,
     and Buyer shall purchase such Engines from Seller. Expiration or
     termination of this Agreement for any reason shall not affect any
     liabilities or obligations of either party which have accrued at the date
     of expiration or termination or which by their nature survive expiration or
     termination (including, without limitation, the obligations under sections
     6, 7, 8, 9 and 13).
 
     10.  FORCE MAJEURE.  Neither party (nor any successor to either party,
including, without limitation the Purchasing Party (as defined in section 12))
to this Agreement shall be liable for delay or failure to perform under this
Agreement which results from any occurrence or event which could not have been
reasonably avoided including, without limitation, accident, action of the
elements, act of God, civil unrest, enemy action, epidemic, explosion, fire,
flood, insurrection, strike, lockout or other labor trouble or shortage, natural
catastrophe, riot, unavailability or shortage of material, equipment or
transportation, war, act, demand or requirement of law or of the Government of
the United States or any other competent governmental authority, or any other
similar cause beyond such party's control, if the party in default makes
reasonable efforts to remove or overcome the effects of such occurrence or
event. If a party believes that any one or more of the above occurrences or
events shall cause a delay or prevent its performance hereunder, it shall
promptly notify the other party in writing of such fact.
 
     11.  RELATIONSHIP OF THE PARTIES.  The relationship established between the
parties by this Agreement during its term shall be solely that of vendor and
vendee. Under no circumstances shall the contractual relationship between the
parties be deemed or construed as one of agency, joint venture, employment or
otherwise. This Agreement does not give either party any right to act as a
representative or agent of the other party or any authority to incur or create
any obligation in the name of or on behalf of the other party.
 
     12.  ASSIGNMENT, SUCCESSORS AND ASSIGNS AND SALE OF SELLER'S
BUSINESS.  Neither party may assign this Agreement or any rights or obligations
hereunder without the prior written consent of the other party; provided,
however, Seller or Buyer, as applicable, may assign, upon written notice to the
other party Buyer and without the other party Buyer's consent, this Agreement or
its interest herein to any affiliate or to any third party succeeding to its
Seller's business. Subject to the foregoing, this Agreement shall bind and inure
to the benefit of Buyer, Seller, and their respective representatives, heirs,
successors and assigns. If Seller desires to sell or transfer more than 50% of
its stock (except for transfers among existing shareholders of Seller or any
trusts for the benefit thereof and among existing shareholders of Seller and
their spouses, siblings and lineal descendants or any trusts for the benefit
thereof) or sell or transfer substantially all of its assets used in connection
with manufacturing of the Engines (a "Change of Control"), Seller agrees to
 
                                       10
<PAGE>   11
 
have the party purchasing or receiving the stock or assets (the "Purchasing
Party") accept assignment of this Agreement subject to the term adjustment
provision contained in section 2, above and the terms of this section 12. After
a Change in Control, and only after a Change in Control, Buyer shall have the
right to have the Costs of Production for any annual period ending subsequent to
such Change of Control audited by an accounting firm (which shall be mutually
acceptable to Buyer and the Purchasing Party or selected in accordance with the
procedure set forth for selecting the Accounting Firm pursuant to section 1(a)
of this Agreement). The sole purpose of the audit conducted pursuant to the
immediately preceding sentence shall be to confirm that Costs of Production for
the Engines reflect a reasonable allocation of Costs of Production between the
Engines and the Purchasing Party's other (non-Engine) products. After a Change
of Control, and only after a Change of Control, Buyer and the Purchasing Party
shall negotiate in good faith and establish mutually agreeable delivery
schedules for Engines to be purchased by Buyer from the Purchasing Party
pursuant to this Agreement (the "Schedules"). The Schedules shall contain terms
for delivery that are in all material respects consistent with the manner in
which Engines are delivered to Buyer by Seller prior to the Change of Control.
Following a Change of Control, subject to the provisions of section 10, if the
Purchasing Party fails to deliver Engines in accordance with the Schedules,
Buyer shall be entitled to indemnification pursuant to and in accordance with
section 8(a) of this Agreement.
 
     13.  ARBITRATION OF DISPUTES.  All disputes or claims arising out of,
resulting from or related to this Agreement shall be finally settled under the
Rules of the American Arbitration Association (the "Rules") by an arbitrator
appointed in accordance with the Rules. If the parties fail to so nominate a
sole arbitrator within 30 days from the date when the claimant's request for
arbitration has been communicated to the other party, the sole arbitrator shall
be appointed in accordance with the Rules. Any decision made by such an
arbitrator within the scope of his or her authority shall be binding upon the
parties. The cost for such arbitrator shall be borne equally between the
parties, but all other costs involved in the arbitration shall be borne
separately by the parties. Each party shall enter into an arbitration agreement
providing reasonable protection to the arbitrator. The place of arbitration
shall be in Milwaukee County, Wisconsin, USA. Judgment on any award rendered by
the arbitrator may be entered by any court of competent jurisdiction. The
parties irrevocably consent and submit to the jurisdiction of any local, state
or federal court in Milwaukee County, Wisconsin, USA.
 
     14.  NOTICES.  Notices permitted or required to be given under this
Agreement shall be deemed sufficient if sent by mail or other delivery service,
facsimile, or, if promptly confirmed in writing, by telephone, addressed to the
parties as set forth below. Notices so given shall be effective upon (a) receipt
by the party to which notice is given or (b) on the fifth day following the date
such notice was posted or transmitted, whichever occurs first. Notices shall be
addressed as follows:

     15.  ENTIRE AGREEMENT.  This Agreement and the exhibits attached hereto
constitute the entire understanding between the parties with reference to the
subject matter hereof and no statements or agreements, oral or written made
prior to the signing of this Agreement shall vary or modify the written terms
hereof. No amendment or modification of this Agreement or release form any of
the provisions hereof shall be valid unless made in writing and signed by the
parties.
 
     16.  WAIVER.  The failure of either party at any time to require
performance by the other party of any provision hereof will in no way affect the
right to require such performance at any time thereafter, nor will the waiver by
either party of a breach of any provision hereof constitute a waiver of any
succeeding breach of the same or any other provision, or constitute a waiver of
the provision itself.
 
     17.  SEVERABILITY.  If any provision of this Agreement is held to be
invalid or unenforceable for any reason, the parties agree that such invalidity
or unenforceability shall not affect any other provision of this Agreement, the
remaining terms, covenants and provisions hereof shall remain in full force and
effect.
 
     18.  GOVERNING LAW.  This Agreement and any disputes hereunder shall be
governed and construed in accordance with the internal laws of the state of
Wisconsin.
 
     19.  HEADINGS.  The headings used in this Agreement are for convenience and
reference purposes only and shall not affect the meaning or interpretation of
this Agreement.
 
     20.  COUNTERPARTS.  This Agreement may be executed in counterparts, each of
which shall be deemed an original, but both of which taken together shall
constitute one and the same instrument.
 
     The parties intending to be bound hereby have caused this Agreement to be
signed by their duly authorized representatives on the day and year first
written above.

                   TWO YEAR LIMITED WARRANTY FOR "GN" ENGINES
 
     Generac warrants to the original purchaser that the "GN" engine will be
free from defects in materials or workmanship for the items and period set forth
below from the date of original purchase. This warranty is not transferable and
applies only to GN-Series Generac warranted engines.

</TABLE>
 
     With the exception of European Community Countries, all units bound for
export shall be warranted for one (1) year in consumer applications, and 90 days
in commercial applications as defined below.
 
     *NOTE: FOR THE PURPOSE OF THIS WARRANTY, "CONSUMER USE" MEANS PERSONAL
RESIDENTIAL HOUSEHOLD USE BY ORIGINAL PURCHASER. THIS DOES NOT APPLY TO UNITS
USED FOR PRIME POWER IN PLACE OF UTILITY. "COMMERCIAL USE" MEANS ALL OTHER USES,
INCLUDING PRIME POWER, RENTAL, CONSTRUCTION, COMMERCIAL, AND INCOME PRODUCING
PURPOSES. ONCE AN ENGINE HAS EXPERIENCED COMMERCIAL USE, IT SHALL THEREAFTER BE
CONSIDERED A COMMERCIAL USE ENGINE FOR THE PURPOSES OF THIS WARRANTY.
 
     During said warranty period, Generac will, at its option, repair or replace
any part which, upon examination by Generac is found to be defective under
normal use and service. All transportation costs under warranty, including
return to the factory if necessary, are to be borne by the purchaser and prepaid
by him. This warranty does not include nominal maintenance and service and does
not apply to an engine which has been subjected to improper or unauthorized
installation, misuse, negligence, accident, overloading, overspeeding, improper
maintenance, repair or storage so as, in Generac's judgment, to adversely affect
its performance and reliability.
 
     **NORMAL WEAR: AS WITH ALL MECHANICAL DEVICES, THE GN-SERIES ENGINES NEED
PERIODIC PARTS SERVICE AND REPLACEMENT TO PERFORM WELL. THIS WARRANTY WILL NOT
COVER REPAIR WHEN NORMAL USE HAS EXHAUSTED THE LIFE OF A PART OR AN ENGINE.
 
     There is no other express warranty. Generac hereby disclaims any and all
implied warranties, including but not limited to those of merchantability and
fitness for a particular purpose to the extent permitted by law. The duration of
any implied warranties which cannot be disclaimed is limited to the time period
(one year) as specified in the express warranty. Liability for consequential,
incidental, or special damages under any and all warranties is excluded to the
extent permitted by law. Some states do not allow limitations on how long an
implied warranty lasts, or the exclusions or limitations of incidental or
consequential damages, so the above limitations or exclusions may not apply to
you. This warranty gives you specific legal rights and you may also have other
rights, which vary from state to state.
 
     For service, see your nearest Generac authorized warranty service facility
or call 1-800-333-1322. Warranty service can be performed only by a Generac
authorized service facility. This warranty will not apply to service at any
other facility. At the time of requesting warranty service, evidence of original
purchase date must be presented.

                     GN ENGINE COMPONENT PRICE ADJUSTMENTS
                 (CRANKCASE, CYL HEAD, GEAR COVER, CRANK, CAM)
 
                   ADJUSTMENT FOR EXCHANGE RATE FLUCTUATIONS
                                      AND
                    ALUMINUM INGOT MARKET PRICE FLUCTUATIONS
 
Component costs are adjusted for fluctuations in aluminum ingot price every six
months based on the following formula.
 
Monthly Al. Rate Deviation = Monthly Avg. Al. Cost -- Base Al. Rate
 
Monthly Al. Consumption = (Al. Weight per engine + 5%) x Monthly volume
 
(Monthly Rate Deviation x Monthly Al. Consumption) + 13% = Total Monthly
Adjustment
 
               Note: Monthly consumption must be calculated by engine model due
to differences in                aluminum weight between models.
 
Component costs are adjusted for fluctuations in currency exchange rates every
six months based on the following formula.
 
Monthly Currency Deviation = Monthly Avg.  Exchange Rate -- Base Exchange Rate
 
(Monthly Currency Deviation x Total Cost of Imported Parts x Monthly Volume) +
13% = Total Monthly Adjustment
 
               Note: Import parts are defined as parts imported into Japan.
Component costs are based in Japanese Yen.
