                                     PART I

                        Item 1 - Description of Business

General

         Top Air Manufacturing,  Inc.  (hereinafter  referred to as "Top Air" or
         the "Company") was incorporated  under the laws of the State of Iowa in
         1981.  Top Air is  engaged in the  business  of  manufacturing  several
         products used primarily in agricultural  operations,  including several
         types of agricultural sprayers, liquid manure handling equipment, grain
         carts and wagons,  milking parlors, seed conveyors,  feeding and forage
         equipment and a line of attachments  and  replacement  parts for all of
         the  products  that the Company  manufactures.  The  Company  currently
         manufactures its products in two facilities,  one in Cedar Falls,  Iowa
         and the other in Onarga, Illinois.

Acquisitions

         In January,  1997,  Top Air  indirectly  acquired  all of the assets of
         Ficklin  Machine Co., Inc.  ("Ficklin  Machine") by  purchasing  all of
         Ficklin Machine's capital stock in exchange for 1,150,000 shares of Top
         Air's no par value common stock.

         In June 1995, the Company acquired  substantially  all of the assets of
         Clay  Equipment  Corporation  in  exchange  for  837,666  shares of the
         Company's no par value common stock and the  assumption  by the Company
         of certain liabilities of Clay Equipment Corporation.

Business of Issuer

         Principal Products and Markets

         Sprayers.   The  Company  currently   manufactures   several  types  of
         agricultural   sprayers   including  skid  mount,   two-wheel   models,
         three-wheel  models,  saddle tank  models,  home lawn  models,  trailer
         sprayers, tandem wheel sprayers, T-Tank Sprayers, Master Link sprayers,
         Terrain Master sprayers and models which can be mounted in the bed of a
         pickup truck. The sprayers are sold in sizes ranging from a 14 to 1,100
         gallon  capacity.  The Company also offers various  accessories for the
         sprayers including several models of folding and self-leveling booms in
         various lengths and designs.

         The sprayers are used  primarily  for farming  activities.  They can be
         pulled  directly  by a tractor  or they can be hooked to a disc so that
         their  combined  functions  allow the farmer to eliminate one trip over
         the  ground.  The  sprayers  are used for  spraying  jobs of all types,
         including the spraying of chemicals, fertilizers, insecticides and weed
         killers. They are used by farmers and commercial sprayers primarily for
         row  crops,  but  can  also  be  used on  other  crops,  golf  courses,
         cemeteries, etc. The wheels may be adjusted to compensate for difficult
         row  crop  widths.  Trees  and  shrubs  may be  sprayed  by a hand  gun
         attachment to the sprayers.

         Manure  Handling  Equipment.  This product group  consists of a line of
         tanks  ranging in size from  2,600  gallons  to 6,000  gallons,  either
         trailer  mounted or truck  mounted to  transport  animal  manure from a
         storage  pit or a storage  lagoon to a farm  field.  The manure is then
         spread  on top of the  ground  or  injected  several  inches  under the
         surface as a fertilizer  which is very cost effective as opposed to the
         purchase of a  commercial  substitute.  In addition to the tanks,  this
         product  group  includes  several types of pumps to agitate the storage
         pit or storage lagoon and subsequently load the tank.

         Grain Carts and  Wagons.  The Company  manufactures  a wide  variety of
         agricultural  grain  handling  equipment,  including  side  and  center
         unloading  (gravity)  wagons,  ranging  in size from 190 to 720  bushel
         capacity,  and grain  carts  equipped  with  integral,  folding 14 inch
         diameter  augers,  which range in size from 400 to 750 bushel capacity.
         The grain  wagons  consist  of two basic  units,  the grain box and the
         wagon running gear,  which can be sold  together or  separately.  Grain
         carts are most  commonly sold as complete  units with large  floatation
         tires.

         Grain  carts are used in the farm fields  during the harvest  season to
         transport  grain from the  combine to nearby  roads  where the grain is
         transferred  from the cart to trucks or grain  wagons for  transport to
         storage facilities. Carts are favored for use in the field because they
         are  pulled by  tractors  and can be pulled  across wet fields in which
         trucks often  get stuck.  Grain  wagons can also be used during  spring
         planting as seed tenders for grain drills and planters.

         Seed  Conveyor.  The trend in agriculture is away from handling seed in
         bags and toward bulk handling. Since seed is very sensitive to cracking
         and breaking which reduces germination,  the traditional auger elevator
         or chain type  conveyor is less  desirable in seed  handling.  The seed
         conveyor  utilizes  a poly  vinyl  type  of  belt  with  rubber  cleats
         vulcanized to the belt which substantially  reduces damage to the seed.
         The seed  conveyor is  available  in either a six-inch  or  twelve-inch
         width.  The six-inch wide conveyor is normally mounted on a gravity box
         or a grain  drill  while  the  twelve-inch  wide unit is  mounted  on a
         trailer for mobility.

         Milking  Parlors.  Dairy  farmers who  remodel or build new  facilities
         normally  install a  milking  parlor or  expand  the  existing  milking
         parlor. The milking parlor  substantially  reduces the time required to
         complete the milking  process  since more cows can be milked with fewer
         man hours.  Although the Company  manufactures several types of milking
         parlors, the most popular type is the rapid exit 90 degree parlor.

         Feeding  and  Forage.  Feeding  and forage  equipment  consists of belt
         feeders, belt conveyors and silo unloaders. These products are normally
         used in a  configuration  to convey and feed chopped hay or corn silage
         along  with  other  ingredients  to dairy  cows or beef  cattle.  These
         products are normally found in a small to medium size farm operation.

         Replacement  Parts and  Attachments.  The Company stocks a full line of
         repair  parts  and  attachments  to fit  all of the  products  that  it
         manufactures.  The Company  distributes  these parts to  retailers  and
         utilizes  them in its own  manufacturing  processes.  The  Company  has
         actively  promoted  these parts and has  established  itself as a major
         supplier in the replacement parts market.

         Other Products. The Company also custom manufactures products for other
         firms on a  contract  basis.  Traditionally,  these  have been  limited
         production runs of new designs.

Method of Distribution

         The   Company   has  seven   salesmen   and   thirteen   manufacturers'
         representatives  calling  upon  dealers and  distributors  in seventeen
         states and  Canada.  The  Company's  efforts  are  ongoing to  continue
         expanding its sales  territory  into  additional  states and to further
         enhance market  penetration in the current marketing areas. The Company
         is selling its products  primarily to  implement  dealers,  farm supply
         stores  and  feed  stores   located   primarily  in  lesser   populated
         agricultural areas for resale to farmers,  tradesmen and to the general
         public for commercial and individual use.

Seasonal Factors

         In fiscal  1998,  approximately  60% of the  Company's  sales  occurred
         during the last six months of the year,  compared to approximately  75%
         of sales for the same  period  in fiscal  1997.  This  decrease  in the
         seasonality  of  sales is  primarily  a result  of the  acquisition  of
         Ficklin Machine. Ficklin Machine's strongest shipping months are August
         through  September  whereas  Top Air's  heaviest  shipping  months  are
         typically October through May.

Competitive Conditions

         The  Company  competes  with  a  large  number  of  other  agricultural
         equipment manufacturers and suppliers. The Company's products, however,
         are considered sufficiently different so that the Company can establish
         and maintain a market for its products. In addition, the Company offers
         a full line of sprayer  products,  liquid  manure  handling  equipment,
         grain  wagons  and  carts,  milking  parlors  and  feeding  and  forage
         equipment  that add to the  Company's  ability to penetrate the market.
         The Company offers  various dating and billing  programs that allow the
         Company's  dealers  incentive  to stock larger  quantities  of products
         without the necessity to commit financial  resources  several months in
         advance.  This also allows the Company to plan its production on a more
         convenient basis.

Major Customers

         The Customer base is sufficiently  broad that no customer  accounts for
         10% or more of the Company's sales.

Backlog Orders

         The Company had a sales backlog of approximately $800,000 as of May 31,
         1998  compared to an immaterial  sales backlog as of May 31, 1997.  The
         May 31,  1998  backlog  consists  mainly  of  grain  carts  and  wagons
         scheduled for summer delivery. See "Seasonal Factors."

Source and Availability of Raw Materials

         The Company purchases its raw materials from a number of suppliers. The
         Company has had no difficulty in obtaining  component parts in the past
         and  does  not  anticipate  any  difficulty  in  obtaining   sufficient
         component parts and raw materials as production increases.

Patents and Trademarks

         The Company has received a design  patent on the  three-wheel  sprayer,
         the master-link  sprayer and the self-leveling  boom, and has trademark
         registrations  for Top-Air(R) and E-Z Boy(R).  With its  acquisition of
         Clay Equipment,  the company now sells a line of agricultural spreaders
         under the  registered  trade name of "Better  Built." While the Company
         believes that its patents and trademarks have  significant  value,  the
         Company is not  dependent  upon patents,  trademarks,  service marks or
         copyrights.

Environmental Compliance

         The Company  believes  that it is presently in  substantial  compliance
         with all existing applicable environmental laws and does not anticipate
         that such  compliance will have a material effect on its future capital
         expenditures, earnings or competitive position.

Employees

         On May 31, 1998, the Company's plant and executive offices employed 135
         people on a  full-time  basis.  Of this  number,  seven  are  executive
         officers and the  remainder  are sales  representatives,  office staff,
         production  workers,  and truck  drivers.  Fifty  full-time  production
         workers are currently covered under a collective  bargaining  agreement
         with Local 1728 of the IAMAW (the "Union")  which runs through June 30,
         2001.

Research and Development

         Research  and  development  costs  incurred for the years ended May 31,
         1998, 1997 and 1996 were $486,985, $448,350 and $400,916, respectively.
         Research and development activities consist primarily of wages paid for
         the design and testing of new  equipment and  improvements  to existing
         equipment.

                        Item 2 - Description of Property

The Company's operations are located in Cedar Falls, Iowa and Onarga,  Illinois.
The Cedar Falls location is the Company's headquarters and consists of an 85,000
square  foot  building  (the  "Cedar  Falls  Facility")  that was  completed  in
November,  1996.  The Cedar Falls  Facility is located in an industrial  park on
nine acres of land and  includes  approximately  7,000  square feet of executive
office  space and an aggregate of  approximately  78,000  square feet devoted to
manufacturing, assembly, and warehousing functions. The Company leases the Cedar
Falls Facility from the City of Cedar Falls,  Iowa (the "City").  The lease term
runs through 2006 and the City holds a five-year  renewal  option.  In the event
that the City  exercises  such  option,  the  Company  shall  have the  right to
purchase  the  Cedar  Falls  Facility  from the City for $1.3  million  upon the
expiration of the five year renewal term.

The Company's Onarga location consists of four buildings  totaling 41,300 square
feet on eight and one-half acres (the "Onarga  Facility").  The Onarga  Facility
includes  approximately  925 square feet of office space,  15,750 square feet of
manufacturing  space and  24,625  square  feet of  warehouse  space.  The Onarga
Facility  is subject to a  mortgage  dated  January  13,  1997 of  approximately
$850,000 in favor of Norwest Bank Iowa, N.A. The Company believes both the Cedar
Falls Facility and the Onarga Facility are adequately insured.

In August 1998,  the Company  began an expansion of the Cedar Falls  Facility to
add  approximately  27,000  square feet to the size of the Cedar Falls  Facility
(the "Expansion") pursuant to the terms of a development  agreement  between the
Company  and the City dated July 13,  1998 (the  "Development  Agreement").  The
Expansion  will allow the Company to  increase  the size of its  assembly  area,
warehouse capacity and research and development  department.  The Expansion will
also enable the Company to increase  production capacity and result in increased
production  efficiencies.   The  Expansion  is  scheduled  to  be  substantially
completed by January 1999 and is  projected  to cost  approximately  $1,000,000.
Under the  Development  Agreement,  the Company will be entitled to 20.5% of the
sale proceeds from the disposition of the Cedar Falls Facility in the event such
facility is sold prior to November 2011. In addition,  the Development Agreement
specifies  that the City shall donate to the Company four acres of land adjacent
to the Cedar Falls Facility.

                           Item 3 - Legal Proceedings

There are no material legal proceedings  pending to which the Company is a party
or of which any of its property is the subject.  No proceedings  were terminated
during the fourth quarter of the fiscal year covered by this Report.

          Item 4 - Submission of Matters to a Vote of Security Holders

There were no matters  submitted to a vote of security holders during the fourth
quarter of the fiscal year covered by this Report.

         As of May 31, 1998 the Company had  approximately 850 holders of record
         of the Company's common stock.

Dividends

         The holders of common shares are entitled to receive dividends when and
         as declared by the Board of Directors. Except for certain provisions in
         the Company's loan agreement with Norwest Bank Iowa, N.A. regarding the
         maintenance  of certain  working  capital and tangible  equity  levels,
         there are no agreements that restrict  dividend  payments.  The Company
         has never paid a cash dividend.  Because the Company  currently intends
         to retain any earnings to finance the  development of its business,  it
         does not anticipate  payment of any cash  dividends in the  foreseeable
         future.

Recent Sales of Unregistered Stock

         In January 1997, the Company issued 1,150,000 shares of common stock to
         Wayne W. Whalen in connection with the Company's acquisition of Ficklin
         Machine in a transaction  exempt from registration  pursuant to Section
         4(2) of the Securities Act of 1933.

         Also in January 1997,  the Company  issued to Gregory Wilson a ten year
         option to purchase  50,000  shares of the  Company's  common stock at a
         price of $1.375 per share in a  transaction  exempt  from  registration
         pursuant to Section 4(2) of the  Securities Act of 1933. The option was
         granted as partial  consideration  in connection with certain  services
         that Mr. Wilson rendered to the Company.  The Company believes that the
         total value of the  consideration  paid was commensurate with the value
         of the  services  the  Company  received.  The  option  is  immediately
         exercisable and includes conditional registration rights.


      Item 6 - Management's Discussion and Analysis of Financial Condition

   Overview

         Financially, fiscal 1998 was very successful. The Company continued its
         trend of delivering record levels of sales and net income. Market share
         gains  were  seen  in  both  existing  territories,   as  well  as  new
         territories. Operating cost margins were improved which translated into
         a higher percentage of operating income as it relates to sales.

         The benefits of recent  acquisitions are also apparent in the Company's
         results of  operations.  Such  acquisitions  diversified  the Company's
         product line which  permitted the Company to post sales  increases in a
         year  that saw  declining  livestock  prices  and  demand  for  related
         equipment.  Product  line  diversification  will  allow the  Company to
         withstand typical product cycles by offering  equipment that is counter
         cyclical.  In addition,  the Company's  acquisitions have substantially
         reduced  the   seasonality   typically   experienced  in   agricultural
         manufacturing, by adding both fall and spring use product offerings.

   Results Of Operations

         Fiscal 1998 Compared to Fiscal 1997

         Net sales increased $2,760,195 to $16,562,461 in fiscal year 1998 which
         represents  a 20% increase  over fiscal 1997 net sales of  $13,802,266.
         The  increase   resulted   primarily  from  strong  sales  of  spraying
         equipment,  grain  wagons and grain carts.  Increases in these  product
         groups were accomplished  through continued geographic expansion of the
         Company's  dealer network,  coupled with  incremental  sales of Ficklin
         Machine for a full twelve  months  during  fiscal 1998.  The  increases
         offset a decline in the net sales of manure handling  equipment,  which
         were negatively affected by low livestock prices throughout the year.

         The Company's gross margin  increased to $5,441,660 in fiscal 1998 from
         $4,566,239  in fiscal  1997,  an increase  of 19%.  This  increase  was
         primarily due to increased  sales volume.  Gross margin as a percentage
         of net sales  decreased to 32.9% in fiscal 1998 from 33.1% in 1997. The
         decrease in margin  resulted from a higher  percentage of  consolidated
         net sales coming from the Ficklin Machine product line, which typically
         carries a slightly lower margin.  However, gross margins of the Ficklin
         Machine  product line were  improved  for fiscal 1998  through  planned
         product mix changes at that  facility.  As a result,  the  consolidated
         gross  margin  percentage  for fiscal  1998 was  somewhat  higher  than
         originally anticipated.

         Operating  expenses  increased  $469,496 to  $3,530,425  in fiscal 1998
         which was a 15% increase from  $3,060,929 in 1997. The increase was due
         to  incremental  expenses  associated  with  the  first  full  year  of
         operation at the Ficklin Machine facility and general expenses relating
         to the higher level of business.  Operating expenses as a percentage of
         net sales continued its downward trend to 21.3% in fiscal 1998 compared
         to 22.2% in fiscal 1997.

         Interest  expense  increased  $185,543 to $370,591 in fiscal 1998 which
         was a 100% increase from $185,048 in fiscal 1997.  The increase was due
         to higher levels of short-term  and long-term debt necessary to finance
         the  operation of Ficklin  Machine and the  purchase of new  production
         machinery for the Cedar Falls plant.  Interest  expense as a percentage
         of net sales increased to 2.2% in fiscal 1998 from 1.3% in fiscal 1997.

         Income tax expense  increased  $78,724 to $560,999 in fiscal 1998 which
         was 16.3%  increase  from  $482,275 in fiscal 1997.  The increase was a
         result of higher earnings.

         Net income increased  $142,631 to $1,000,007 in fiscal 1998 which was a
         16.6%  increase  from  $857,376 in 1997.  Net income as a percentage of
         net sales decreased to 6.0% in fiscal 1998 from 6.2% in fiscal 1997.

         Fiscal 1997 Compared to Fiscal 1996

         Net sales increased $2,173,336 to $13,802,266 in fiscal year 1997 which
         represents  a 19%  increase  over 1996 net sales of  $11,628,930.  This
         increase  can be  attributed  to strong  sales in  spraying  and manure
         handling equipment resulting from sales programs implemented during the
         year. In addition,  incremental  sales increased in connection with the
         acquisition of Ficklin Machine.  The increases were offset by decreases
         in a number of product lines  formerly sold by Clay Equipment that were
         sold off  during  the year to enable  the  Company  to  concentrate  on
         products with the greatest potential for growth and profitability.

         The  Company's  gross  margin  increased  to  $4,566,239  in 1997  from
         $3,904,285  in 1996, a 17% increase,  primarily due to increased  sales
         volume. Gross margin as a percentage of net sales decreased to 33.1% in
         1997  from  33.6%  in  1996.  This  decrease  is due  primarily  to the
         incremental  sales from the  Ficklin  Machine  acquisition  achieving a
         lower percentage of profit than Top Air has  historically  experienced.
         The margins  experienced  by Ficklin  Machine in the spring months have
         typically been lower than their margins on an annual basis.

         Operating expenses increased $355,219 to $3,060,929 in 1997 which was a
         13%  increase  from  $2,705,710  in  1996.  The  increase  was  due  to
         incremental expenses associated with the acquisition of Ficklin Machine
         and to the higher level of business. Operating expenses as a percentage
         of net sales decreased to 22.2% in 1997 compared to 23.3% in 1996.

         Interest expense decreased $12,786 to $185,048 in 1997 which was a 6.5%
         decrease from $197,834 in 1996.  The decrease was a net result of lower
         levels of operating  debt carried  throughout  the year,  offset by the
         additional  debt  assumed in  connection  with the  purchase of Ficklin
         Machine.  Interest  expense as a percentage  of net sales  decreased to
         1.3% in 1997 from 1.7% in 1996.

         Income tax expense  increased  $109,269 to $482,275 in 1997 which was a
         29.3%  increase  from  $373,006 in 1996.  The increase was  primarily a
         result of higher earnings.

         Net income  increased  $179,988  to  $857,376 in 1997 which was a 26.6%
         increase from $677,388 in 1996. Net income as a percentage of net sales
         increased to 6.2% in 1997 from 5.8% in 1996.

         Liquidity

         Due to the seasonality of the period of use for the Company's products,
         it is necessary for the Company to build  inventories ahead and finance
         accounts receivable for extended terms. As a result, the Company's need
         for working capital continues to increase as sales grow.

         The Company has used a combination of cash  generated  from  operations
         and short-term  bank loans to fund working  capital  requirements.  The
         same   combination   is  intended  to  be  used  to  fund  fiscal  1999
         requirements.  The Company believes it has access to sufficient working
         capital for its present and foreseeable needs and anticipates borrowing
         funds seasonally, as the need arises.

         As of May 31, 1998, the Company had a $4,000,000  line of credit from a
         bank  pursuant  to a credit and  security  agreement  originally  dated
         January 13, 1997 which expires  November 30, 1998 and bears interest at
         the prime rate (8.25% as of May 31,  1998).  As of May 31, 1998,  there
         was $1,620,000 outstanding under the Company's line of credit.

         The Company's  working capital on May 31, 1998 was $5,697,623 which was
         an increase  from  $5,140,589  in fiscal 1997 and  $3,728,790 in fiscal
         1996. Working capital increased primarily as a result of current assets
         being  partially  funded  through  earnings  without the  necessity  to
         utilize short-term borrowings. The current ratio decreased to 2.48:1 in
         fiscal  1998 as  compared to 2.90:1 in fiscal 1997 and 3.43:1 in fiscal
         1996.

         Net cash used in operations  for fiscal 1998 was $663,705,  an increase
         of $327,644 from the cash used in fiscal 1997 of $336,061. The increase
         was  primarily  a  result  of  financing   higher  levels  of  accounts
         receivable and inventories as the Company continues to grow.

         Net cash used in investing  activities during fiscal 1998 was $981,038,
         a decrease  of  $1,034,100  from the cash  generated  in fiscal 1997 of
         $53,062.  The decrease was primarily a result of additional  investment
         in production machinery and equipment.

         Net  cash   provided  by  financing   activities  in  fiscal  1998  was
         $1,386,371,  an increase of $840,371  from cash  provided by  financing
         activities  in  fiscal  1997  of  $546,000.  The  increase  was  due to
         long-term  borrowings to fund purchases of new machinery and short-term
         borrowing  to  fund  increased   levels  of  accounts   receivable  and
         inventories.

         Capital Resources

         In August,  1998 the Company began construction on a 27,000 square foot
         expansion to its Cedar Falls, Iowa facility.  Total cost of the project
         is  expected  to be  approximately  $1,000,000.  Construction  will  be
         substantially  completed by January,  1999.  This expansion will enable
         the  Company to expand  production  capacity  and will allow  increased
         production efficiencies. The Company will use long term debt to finance
         this expansion.

         Year 2000

         Top Air is currently in the process of evaluating its computer  control
         systems for the potential costs and effects of the upcoming  Millennium
         change.  The Company has been advised that its main  computer  hardware
         and software  systems are year 2000 compliant and believes that actions
         required to prepare all other  systems for the year 2000 issue will not
         have  a  material  impact  on its  business,  operations  or  financial
         condition.

                          INDEPENDENT AUDITOR'S REPORT


To the Board of Directors
Top Air Manufacturing, Inc.

express an  opinion  on these  consolidated  financial  statements  based on our
audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated  financial statements referred to above present
fairly,  in  all  material   respects,   the  financial   position  of  Top  Air
Manufacturing,  Inc. and subsidiary as of May 31, 1998 and 1997, and the results

TOP AIR MANUFACTURING, INC. AND SUBSIDIARY

NOTES TO FINANCIAL STATEMENTS

Note 1.  Nature of Business and Significant Accounting Policies

Nature of business: The Company's operations consist of the design,  manufacture
and sale of agricultural  equipment and repair and replacement  parts to dealers
located  primarily  in the  midwestern  states on credit  terms that the Company
establishes for individual customers.

Significant accounting policies:

Principles of consolidation:  The consolidated  financial statements include the
accounts  of  the  Company  and  its  subsidiary,   Ficklin  Machine,  which  is
wholly-owned.  All significant  intercompany accounts and transactions have been
eliminated.

Accounting estimates: The preparation of financial statements in conformity with
generally accepted  accounting  principles requires management to make estimates
and  assumptions  that affect the reported  amount 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.

Cash and cash  equivalents:  For purposes of reporting  cash flows,  the Company
considers all money market funds and savings accounts to be cash equivalents.

Inventories:  Inventories are valued at the lower of cost  (first-in,  first-out
method) or market.

Property and  equipment and  depreciation:  Property and equipment is carried at
cost.  Depreciation  on property and equipment is computed by the  straight-line
method over the estimated useful lives of the assets.

Goodwill:  Goodwill resulting from the Company's  acquisition of Ficklin Machine
is  being  amortized  over  15  years  using  the  straight-line  method  and is
periodically  reviewed  for  impairment  based  upon  an  assessment  of  future
operations   to  ensure  that  they  are   appropriately   valued.   Accumulated
amortization on goodwill  totaled  $103,195 and $28,144 at May 31, 1998 and 1997
respectively.

Revenue recognition:  Sales of all products are recognized as goods are shipped.

Income taxes: Deferred taxes are provided on a liability method whereby deferred
tax assets are  recognized for deductible  temporary  differences  and operating
loss  carryforwards  and deferred tax  liabilities  are  recognized  for taxable
temporary  differences.  Temporary  differences are the differences  between the
reported  amounts of assets and  liabilities  and their tax bases.  Deferred tax
assets are reduced by a valuation  allowance when, in the opinion of management,
it is more likely than not that some  portion or all of the  deferred tax assets
will not be realized.  Deferred tax assets and  liabilities are adjusted for the
effects of changes in tax laws and rates on the date of enactment.

Research  and  development:  Research  and  development  costs  are  charged  to
operations as they are incurred.

Stock options issued to employees:  In fiscal year 1997, the Company adopted the
provision of SFAS No. 123,  "Accounting  for  Stock-Based  Compensation",  which
establishes  a fair  value  based  method  for the  financial  reporting  of its
stock-based  employee  compensation  plans.  However,  as  allowed  by  the  new
standard,  the Company has elected to continue to measure compensation using the
intrinsic value based method as prescribed by Accounting Principles Board Option
No.  25,  "Accounting  for  Stock  Issued  to  Employees."  Under  this  method,
compensation is measured as the difference between the market value of the stock
on the grant  date,  less the  amount  required  to be paid for the  stock.  The
difference, if any, is charged to expense over the periods of service.

Fair  value of  financial  instruments:  The  carrying  amount  of cash and cash
equivalents,  trade  receivables and accounts  payable  approximates  fair value
because of the short  maturity of these  instruments.  The  carrying  amounts of
notes  receivable,  current notes payable and long-term  debt  approximate  fair
values  because these  instruments  bear interest at  approximate  current rates
available to the Company for similar instruments.


                                      F-8
<PAGE>

Earnings per share:  In 1997,  the  Financial  Accounting  Standards  Board (the
"FASB")  issued  Statement  No. 128,  "Earnings  Per Share."  Statement  No. 128
replaced the  calculation  of primary and fully diluted  earnings per share with
basic and diluted  earnings per share.  Basic  earnings per share is computed by
dividing net income  available to common  stockholders  by the weighted  average
number of shares  outstanding.  In computing  diluted  earnings  per share,  the
dilutive  effect of stock  options  during the periods  presented as well as the
effect of contingently issuable shares also increase the weighted average number
of shares.

The Company  initially applied Statement No. 128 for the year ended May 31, 1998
and has  restated  all per share  information  for  prior  years to  conform  to
Statement No. 128.

Recently  issued  accounting  standards:  In June 1997, the FASB issued SFAS No.
130,  "Reporting  Comprehensive  Income",  and SFAS No. 131,  "Disclosure  about
Segments of an Enterprise and Related  Information",  both of which are required
to be adopted for fiscal years  beginning  after December 15, 1997. SFAS No. 130
will require the Company to report in its  financial  statements  all  non-owner
related  changes in equity for the  periods  being  reported.  SFAS No. 131 will
require  the  Company  to  disclose  revenues,  earnings,  and  other  financial
information pertaining to the business segments by which the Company is managed,
as well as what factors management used to determine these segments. The Company
is currently  evaluating the  requirements  of SFAS NO. 130 and 131 to determine
how to present the required  information in its financial statements and related
disclosures.

Inventories at May 31, 1998 and 1997 consisted of the following:

Note 3.  Pledged Assets and Related Debt

The Company has a line of credit  agreement  with a bank which expires  November
30, 1998,  under which they may borrow up to $4,000,000 in current notes payable
based on a percentage of inventory and trade receivables. Based on the levels of
inventory and trade  receivables,  the total amount  available could be borrowed
under this  agreement at May 31, 1998.  The interest rate on advances under this
agreement is the bank's prime rate  (effective  rate of 8.25% at May 31,  1998).
The Company has borrowings on this line of $1,620,000 and $432,000 as of May 31,
1998 and 1997, respectively. (a)

Note 6.  Stock-Based Compensation

At May 31,  1998,  the  Company  has a  stock-based  compensation  plan which is
described below. As permitted under generally  accepted  accounting  principles,
grants  under this plan are  accounted  for  following  APB  Opinion  No. 25 and
related interpretations.  Accordingly,  no compensation cost has been recognized
for  grants  under  the  plan.  Had  compensation   cost  for  the  stock  based
compensation  plan been  determined  based on the grant date fair  values of the
awards (the method prescribed in SFAS No. 123), reported net income and earnings
per share would have been reduced to the pro forma amounts shown below:

The  Company  has a stock  option plan  adopted in 1993 which  provides  for the
issuance of a maximum of 425,000  shares of common stock to officers,  directors
and key employees at a price per share of not less than 100% of the market price
at the date of grant.  The options  granted  under this plan become  exercisable
over three years.

In  addition,  the Company  granted  options to purchase  50,000 share of common
stock of the Company to a  non-employee  in connection  with the  acquisition of
Ficklin Machine. See Note 10.

The  fair  value  of each  grant  is  estimated  at the  grant  date  using  the
Black-Scholes   option-pricing   model  with  the   following   weighted-average
assumptions for grants:

Earnings Per Share

In compliance  with  Financial  Accounting  Standards  Board  Statement No. 128,
"Earnings  per  Share,"  issued in  February  1997,  the Company has changed its
method of computing  earnings  per share  effective  for fiscal 1998.  All prior
periods  presented have been restated to conform to the new  requirements  which
exclude  contingently  issuable  shares and the dilutive effect of stock options
from the number of  weighted  average  shares used in the  computation  of basic
earnings per share. The effect of Statement 128 on diluted earnings per share is
immaterial  compared to previously  disclosed fully diluted  earnings per share.
Basic and diluted earnings per share are calculated as follows:

                                                     Year Ended May 31,
                                            1998           1997            1996

Basic earnings per share              $      0.20     $     0.19      $     0.17

Diluted earnings per share:

Effect of dilutive securities, 
  employee stock options                  161,227         88,066          46,047

Diluted earnings per share            $      0.19     $     0.19      $     0.17


At May 31,  1998,  1997 and  1996,  respectively,  67,500,  none and  67,000  of
employee stock options were outstanding but were not included in the computation
of diluted  earnings per share because the options'  exercise  price was greater
than the average market price of the common shares.

Note 10.  Business Acquisitions

On January 15, 1997 the Company acquired all of the issued and outstanding stock
of Ficklin Machine of Onarga,  Illinois in exchange for 1,150,000  shares of the
Company's no par value  common  stock.  As a result,  Ficklin  Machine  became a
wholly-owned subsidiary of the Company.

Ficklin Machine designs, manufactures and distributes grain wagons and carts and
small lawn and garden sprayers.  The Company  currently  intends to continue the
business of Ficklin Machine in substantially  the same manner as conducted prior
to the  acquisition.  The  acquisition  has been  accounted  for by the purchase
method  and the  results of  operations  of  Ficklin  Machine  since the date of
acquisition are included in the financial statements.

Unaudited pro forma  consolidated  condensed  financial  statements for the year
ended May 31, 1997 and 1996 as though  Ficklin had been  acquired as of March 6,
1996, Ficklin Machine's date of inception, are as follows:

Net sales                             $   17,213,000       $   12,681,000
Net income                                   923,000              705,000
Earnings per share:
Basic                                           0.18                 0.17
Diluted                                         0.18                 0.17

On June  26,  1995  the  Company  acquired  certain  assets  of  Clay  Equipment
Corporation  ("Clay") of Cedar  Falls,  Iowa in exchange for the  assumption  of
approximately  $2,500,000 of liabilities  and 837,666 shares of the Company's no
par value common stock with a value of  approximately  $628,000.  In  connection
with the issuance of these shares, the Company incurred stock registration costs
of approximately $29,000. Clay designed, manufactured, and distributed livestock
equipment and other  agricultural  related  products,  primarily manure spreader
wagons and milking equipment. The Company moved the combined operations to Cedar
Falls,  Iowa in October 1996 where the Company has entered into a lease with the
City of Cedar Falls,  Iowa (See Note 11). In association  with the move the City
purchased the land and building of the former Clay site under a flood relocation
plan.  The City withheld  $131,500 of the purchase  price for possible  clean up
costs  after the former  Clay site was  demolished.  Also,  as part of the flood
relocation  plan the Company sold  equipment  and was  reimbursed by the City of
Cedar Falls for the moving costs or  replacement  of equipment with a book value
of $755,546.  All proceeds and reimbursements were received by the Company.  The
acquisition  has been  accounted  for by the  purchase  method  and  results  of
operations of Clay since the date of  acquisition  are included in the financial
statements.

Lease Commitments and Subsequent Events

The Company  has  entered  into a 10 year  noncancelable  agreement  to lease an
85,000  square foot facility from the City of Cedar Falls,  Iowa  ("City").  The
lease requires monthly payments of $16,722 plus insurance,  utilities, and other
expenses to be paid by the Company.  The City has the option to renew and extend
the lease for an  additional 5 years at the end of the original  lease term with
an  increase  in  monthly  rental  not to  exceed  3%.  At the end of the  lease
extension  period,  the  Company  has the option to purchase  the  facility  for
approximately  $1.3 million plus all reasonable  costs and expenses  incurred by
the City for the sale. The lease is being accounted for as an operating lease.

The total minimum rental commitment,  including the extension period, at May 31,
1998 is approximately $2,700,000 which is due as follows:

Year ending May:
           1999                                 $  200,000
           2000                                    200,000
           2001                                    200,000
           2002                                    200,000
           2003                                    200,000
           Thereafter                            1,700,000
                                               -----------
                                               $ 2,700,000
                                               ===========

Under this agreement,  the Company incurred  approximately $200,000 and $143,000
in rent expense for the years ended May 31, 1998 and 1997, respectively.

On July 13, 1998 the Company received a contribution of approximately 4 acres of
land  from  the  City  in  exchange  for an  agreement  to  expand  its  current
manufacturing  facilities.  Subsequently,  the  Company  broke  ground  on  this
expansion which is expected to cost approximately $1,000,000 and be completed in
January 1999. As a part of this agreement, in the event that the existing 85,000
square foot facility  discussed  above is sold prior to the  Company's  right to
exercise its purchase option, the Company would receive 20.5% of the proceeds of
the sale.  The cost of the expansion is expected to be financed with  additional
long-term debt under terms which have not yet been determined.

the performance of any agreement on its part herein  contained or as a waiver by
Lessee of any lights or claims which  Lessee may have against  Lessor under this
Lease or  otherwise,  but any recovery  upon such lights and claims shall be had
from Lessor  separately,  it being the intent of this Lease that Lessee shall be
unconditionally   and   absolutely   obligated  to  perform  fully  all  of  its
obligations, agreements and covenants under this Lease (including the obligation
to make Lease Payments). Lessee may, however, at its own cost and expense and in
its own name or in the  name of  Lessor,  prosecute  or  defend  any  action  or
proceeding or take any other action  involving  third persons which Lessee deems
reasonably  necessary  in order to secure or  protect  its light of  possession,
occupancy  and use of the  Project,  and in such event Lessor  hereby  agrees to
cooperate  fully  with  Lessee and to take all  action  necessary  to effect the
substitution  of Lessee for Lessor in any such  action or  proceeding  if Lessee
shall so request.

         4. Lessor's Covenants. Lessor covenants and agrees:

             (a) That Lessor owns the  premises  and has good and legal right to
lease said  premises  to Lessee and that  Lessor  will put Lessee in  possession
thereof,  and, so long as Lessee pays the Lease Payments and Additional Payments
hereby  reserved and observes and performs the several  covenants,  stipulations
and agreements  provided on Lessee's part, Lessee shall peaceably hold and enjoy
the demised  premises during the term hereof without any  interruption by Lessor
or by any person rightfully claiming under Lessor;

             (b) That Lessee may, at its sole cost and expense,  make other such
additions,  changes and alterations in and to any part of the premises as Lessee
from  time to time may deem  necessary  or  advisable,  subject  to the  express
conditions set forth in Paragraph 5 hereof,

             (c) That Lessee,  notwithstanding  the provisions of Paragraph 5(e)
hereof,  shall have the right to contest any  mechanic's  or other  similar lien
filed  against  or upon the  described  premises  if within  the  30-day  period
referred to in said Paragraph  5(e) hereof it notifies  Lessor in writing of its
intention to do so and, if requested by Lessor,  deposits with Lessor a bond (or
other reasonably  acceptable security) in favor of Lessor, with a surety company
reasonably  acceptable  to  Lessor as  surety,  in the penal sum of at least the
amount  of the lien  claim  so  contested  plus an  additional  amount  equal to
interest  thereon  for six months at the  current  statutory  rate of  interest,
indemnifying and protecting Lessor from and against any liability, loss, damage,
cost  and  expense  of  whatever  kind or  nature  growing  out of or in any way
connected  with said asserted  lien in the  contesting  thereof,  but all on the
condition  that  Lessee  diligently   prosecute  such  contest,   at  all  times
effectively  stay or prevent any official or judicial sale of the  premises,  or
any part thereof or interest therein,  under execution or otherwise,  and pay or
otherwise satisfy any final judgment  adjudging or enforcing such contested lien
claim and thereafter promptly procure record release or satisfaction thereof;

             (d) That any part of the structure and any fixtures paid from funds
of Lessor shall  remain the  property of Lessor.  Lessee shall have the right to
remove from the premises any and all machinery,  equipment and fixtures owned by
or paid for by Lessee, provided,  however, that Lessee shall repair any physical
damage  to  Lessor's  property  caused  by the  removal  of any such  machinery,
equipment or fixtures;

             (e) That Lessee shall have the right,  in its or Lessor's  name, to
contest the validity or amount of any  imposition,  as defined in Paragraph 5(o)
hereof,  which  Lessee is required to bear,  pay and  discharge  pursuant to the
terms of this Lease, by appropriate legal proceedings  instituted,  at least ten
(10) days before the imposition  complained of becomes  delinquent,  but only if
and provided that Lessee,  before  instituting  any such  contest,  gives Lessor
written notice of its intention so to do and, if requested in writing by Lessor,
deposits with Lessor a bond (or other reasonably  acceptable  security) in favor
of Lessor, with a surety company reasonably acceptable to Lessor as surety, in a
penal  sum of at  least  the  amount  of the  imposition  so  contested  plus an
additional  amount  equal to  interest  thereon  for six  months at the  current
statutory rate of interest, conditioned upon the payment, if so adjudged, of the
contested imposition,  together with all interest and penalties accruing thereon
and  costs  of  suit,  if any,  and  provided  further  that  Lessee  diligently
prosecutes  any such  contest,  at all times  effectively  stays or prevents any
official or judicial sale therefore under  execution or otherwise,  and promptly
pays any final judgment  enforcing the  imposition so contested,  and thereafter
promptly secures record release or satisfaction  thereof,  and provided further,
that Lessee hold Lessor  whole and harmless  from any costs and expenses  Lessor

perform its obligations hereunder,  and (ii) grant Lessee the option to purchase
the premises as set forth herein;

             (g) That Lessor  will not  transfer  or  encumber  the  premises or
impose any new  restrictions  on the premises  without  Lessee's  prior  written
consent; and

             (h) That Lessor will construct the building and improvements on the
premises in accordance with the plans,  specifications  and standards  necessary
for Lessee to continue its operations, and approved by Lessee and the EDA.

             (i) To bear, pay and discharge, before the delinquency thereof, all
taxes and assessments, general and special, if any, which may be lawfully taxed,
charged,  levied,  assessed  or imposed  upon or against or be payable for or in
respect of the demised premises, or any part thereof, or any improvements at any
time thereon or Lessee's interest therein or under this Lease, including any new
lawful taxes and assessments not of the kind enumerated above to the extent that
the same are  lawfully  made,  levied or  assessed  in lieu of or in addition to
taxes or assessments now or heretofore  customarily levied against said premises
or against comparable real property in general,  and further including all water
and sewer charges,  assessments,  and other governmental charges and impositions
whatsoever, foreseen or unforeseen.

         5. Lessee's Covenants. Lessee covenants and agrees:

             (a) To pay the Lease  Payments at the time and in the manner herein
provided to Lessor or  Lessor's  order at such place as may from time to time be

             (b) To assume  full  responsibility  for all  maintenance,  upkeep,
repair,  replacement  and  improvement of any and all  buildings,  improvements,
machinery,  equipment,  fixtures and  appurtenances of any type now or hereafter
located upon said property, and for the care and maintenance of all exterior and
unimproved portions thereof. and to hold Lessor harmless from any responsibility
or liability therefore of any type whatsoever;

             (c) To make no additions, changes or alterations in and to any part
of the premises,  and  improvements  thereon,  which will  adversely  affect the
structural  strength of any part of the same or which would change the character
of said premises and  improvements  so that the premises  would not constitute a
"facility" as defined in Iowa law. All additions,  changes and alterations  made
by Lessee, upon said conditions,  shall W be made in a workmanlike manner and in
strict  compliance with all laws and ordinances  applicable  thereto,  (ii) when
commenced,  be  prosecuted  to  completion  with due  diligence,  and (iii) when
completed, be deemed a part of the premises;  provided,  however, that additions
of  machinery,  equipment  and fixtures to the  premises by Lessee,  the cost of
which is financed  totally by funds of Lessee  independent of any  non-financing

renewals or  replacements  of items owned by Lessor at the time of  execution of
this lease;

             (d) Not do or permit  others under its control to do any work in or
about  the  premises  or  related  to  the  repair,   rebuilding,   restoration,
replacement,  alteration  of or addition to the  premises,  or any part thereof,
unless Lessee shall have first procured and paid for all requisite municipal and
other governmental  permits and  authorizations.  All such work shall be done in
good and  workmanlike  manner and in compliance  with all  applicable  building,
zoning and other laws,  ordinances,  governmental  regulations and requirements,
and in accordance with the  requirements,  rules and regulations of all insurers
under the policies required to be carried hereby;

             (e) Not do or suffer  anything to be done whereby the premises,  or
any part thereof, may be encumbered by any mechanic's or other similar lien, and
if,  whenever  and as often as any  mechanic's  or other  similar  lien is filed
against the premises, or any part thereof, purporting to be for or on account of
any labor done or materials or services  furnished in  connection  with any work
in, on or about the  premises  done by, for, or under the  authority  of Lessee,
Lessee shall discharge the same of record within thirty (30) days after the date
of films or provide security therefore which is reasonably acceptable to Lessor.
Lessee  hereby  acknowledges  and gives notice to all other  parties that Lessor
does not  authorize  or  consent  to and shall  not be  liable  for any labor or
materials  furnished Lessee or anyone claiming by, through, or under Lessee upon
credit,  and that no  mechanic's  or  other  similar  lien  for any such  labor,
services or materials shall attach to or affect the reversionary or other estate
of Lessor in and to the premises or any part thereof,

             (f) If at any  time  during  the  term of this  Lease  the  demised
premises or any part thereof is damaged or destroyed by fire or other  casualty,
to proceed  with due  diligence  to  repair,  restore,  rebuild or replace  said
damaged  or  destroyed  portion  thereof  to as  good  condition  as it  was  in
immediately prior to such damage and destruction, subject to such alterations as
Lessee may elect to make as otherwise  permitted  herein.  Before commencing the
work of repairing,  restoring, rebuilding or replacing the improvements as above
provided,  there shall be delivered to Lessor performance and labor and material
payment  bonds with  respect to such work and in the full amount of the contract
covering  such  work  made by the  person  which  contracts  to do such  work as
principal and a surety company or companies reasonably satisfactory to Lessor as
surety and in form  satisfactory  to Lessor.  Said bonds  shall name  Lessor and
Lessee as joint  obligees.  In the  event  that any such  damage or  destruction
occurs,  all of the  insurance  monies  collected  or payable on account of such
damage or destruction on or under the policy or policies of insurance maintained
by Lessee pursuant to the requirements hereof shall be payable jointly to Lessor
and Lessee as their  interests  appear,  and  thereafter  endorsed by such other
parties to Lessee and to the person or persons performing such work or providing
materials  therefore upon receipt by Lessor,  from time to time, of certificates
signed by both  Lessee  and an  architect  or  engineer  selected  by Lessee and
reasonably  approved in writing by Lessor (i) requesting  payment of a specified
amount of such  funds and  directing  to whom such  amount  shall be paid;  (ii)
stating  that the amount  requested  either has been paid by Lessee or is justly
due to  contractors  or other  persons who have  performed  the work or provided
necessary   materials  in  the  repair  and   rebuilding  of  the  premises  and
improvements,  and briefly describing such work and materials,  and stating that
the  requested  amount does not exceed the fair value of such work or materials;
(iii)  stating that,  except for the amounts if any stated in said  certificate,
there are no outstanding  indebtedness which are then due and payable for labor,
wages,  materials,  supplies  or  services  in  connection  with the  repair  or
rebuilding of the damaged  improvements which, if unpaid, might become the basis
of a mechanic's or other similar lien upon the premises or any part thereof, and
(iv) stating that no part of the several  amounts paid or due, as stated in said
certificate,  has been or is being  made the  basis  for the  withdrawal  of any
monies in any previous or then pending  application  pursuant to this Paragraph.
All  insurance  monies not  required to be used for such  purposes  shall,  upon
receipt by Lessor of a certificate  by said  architect or engineer that the work
has been  completed and that no liens exist,  become the property of Lessee.  If
the insurance  monies so collected by the Lessee are  insufficient  in amount to
pay in full the cost of all repairs,  restorations,  rebuilding and replacements
of said damaged or destroyed improvements,  Lessee shall provide and furnish all
other  monies  necessary  to  complete  fully  all such  repairs,  restorations,
rebuilding and replacements;

             (g)  Anything in this Lease to the contrary  notwithstanding,  that
Lessor  shall  have the  right at any  time  and from  time to time to  withhold
payment of endorsement of all or any part of the insurance monies to Lessee,  as
generally  provided in Paragraph 5(f) hereof, in the event (i) Lessee is then in
default in the payment of rent or other charges as provided herein,  (ii) Lessor
has given  notice to Lessee of any other  default  on  Lessee's  part under this
Lease,  or (iii) an act of  default  as  described  in  Paragraph  7 hereof  has
occurred.  In the event Lessee shall cure the defaults  specified  above or such
defaults  cease to exist,  Lessor shall make such  payments  from the  insurance
monies to Lessee in  accordance  with the  provisions  of this Lease;  provided,
however,  that if this Lease is  terminated  or Lessor  otherwise  re-enters and
takes  possession  of the  premises  without  terminating  this Lease  under the
provisions of Paragraph 7 hereof,  Lessor may itself use such  insurance  monies
for the  payment  of the  reasonable  and  necessary  charges  of  such  persons
providing  work and  materials  for the  repairs,  restoration,  rebuilding  and
replacements of the damaged improvements;

             (h) That the real  property  and all  buildings,  improvements  and
fixtures  located  thereon at the time of execution of this Lease,  and all work
and materials on the buildings and  improvements,  and anything under this Lease
which  becomes,  is deemed to be, or constitutes a part of said premises and the
manufacturing  facility thereon,  and said manufacturing  facility thereon,  and
said  manufacturing  facility  as  repaired,  rebuilt,  rearranged,  restored or
replaced  by Lessee  under the  provisions  of this Lease,  except as  otherwise
specifically  provided  herein,  shall be and remain or become  immediately when
erected or installed, as the case may be, the absolute property of Lessor to the
same extent as if the same had been erected or installed  prior to the execution
of this  Lease,  subject  only to the  express  provisions  of this Lease and as
otherwise  noted in Paragraph  4(b),  provided that no machinery or equipment or
other non-fixture  personal effects of the Lessee purchased and installed on the
premises by Lessee and no part of which is paid for from funds of Lessor or from
the EDA Grant shall be deemed part of the premises;

             (i) To keep and preserve the demised  premises  free from  nuisance
and not permit the use of the same or any part thereof for other than industrial
or manufacturing  purposes as described  herein for the Project;  and not permit
the same to be used for any purpose  forbidden by law,  ordinance or regulation,
or for any  purpose  which  would  be in  violation  of the  Special  Terms  and
Conditions or the General Terms and Conditions of the said EDA Grant,  including
the  governmental  regulations  referred  to  therein,  all of which  terms  and
conditions are hereby incorporated by reference;

             (j) To pay all utility charges  incurred in respect of the premises
and  Lessee's  occupation  thereof,  and if not  paid in due time and if paid by
Lessor at Lessor's  sole  option,  to reimburse  Lessor for such  amounts  paid,
including late charges,  plus interest thereon at the highest lawful rate in the
State of Iowa.

             (k) Not to sublet or assign  Lessee's  interest or any part thereof
in this Lease or the  demised  premises  without  the prior  written  consent of
Lessor,  which  said  consent  shall not be  unreasonably  withheld;  and not to
alienate or permit to be alienated its interest in the demised  premises  (which
shall be deemed to include but not limited to the sale,  lease,  rent, option or
mortgage thereof) provided,  however,  that Lessee shall have the absolute right
to assign  Lessee's  interest in the lease to any corporation or other entity in
connection  with any acquisition of  substantially  all of the assets of Lessee,
acquisition  of 80% or more of the  stock of Lessee  or in  connection  with any
merger involving Lessee;  subject to approval by the United States Department of
Commerce  Economic  Development  Administration;  which  consent  shall  not  be
unreasonably withheld;

             (l) Not to allow  trash,  refuse,  waste  material  or  garbage  to

containers and arrange for the removal  thereof  periodically as required by law
or ordinance;

             (m) Not to  initiate  any  proceedings  of any kind  whatsoever  to
dissolve or liquidate  Lessee or its corporate status without securing the prior
written  consent  thereto of Lessor;  

             (n) To permit  Lessor or Lessor's  agents to enter the  premises at
any reasonable time after giving  reasonable notice during normal business hours
for the purpose of inspection for conformity to the express requirements of this
Lease or making repairs to the premises or to show to prospective  purchasers or
tenants,  subject to the  express  conditions  hereof,  and at other  times upon
reasonable notice to lessee;

             (o) To maintain at all times  during the term of this Lease  public

personal injuries,  including death, in any one accident or occurrence,  and not
less than $500,000 for property  damage in any one accident or occurrence.  Said
policy or policies of insurance  shall contain a provision  that such  insurance
may not be cancelled by the issuer  thereof with not less than thirty (30) days'
advance  written notice to Lessor and Lessee.  Such policy or policies or copies
or  certificates  thereof shall be furnished to Lessor on a current basis at all
times during the term of this Lease;

of Iowa as may be  selected  by Lessee  and  reasonably  approved  in writing by
Lessor,  and  against  loss or  damage  by  water  risks as and when and in such
amounts as such  insurance  is  obtainable  and  generally  carried by owners of
industrial and  manufacturing  plants in Iowa. The term "full  insurable  value"
shall mean, to the maximum extent possible,  the full actual replacement cost of
all  improvements  on the premises.  At all times during the term of this Lease,

payment  of Lease  Payments  as  provided  herein  is in  addition  to all other
obligations imposed herein upon Lessee;

             (r) If default be made in the payment of Lease Payments or any part
thereof  or of any  other  payment  required  to be made to  Lessor by the terms

the premises become vacant during the term of this Lease, then Lessor may at any
time thereafter resume possession thereof by any lawful means, and remove Lessee
and Lessee's  effects by self-help or  proceedings  for  possession  or unlawful
detainer,  or  otherwise,  and in any such event  Lessee shall pay all costs and

to purchase the Project and the above described  property and  appurtenances  at
any time  prior to the  expiration  of one  month  after the  expiration  of the
original Lease Term plus the five (5) year renewal of said lease, upon the terms
and conditions hereinafter set forth:

             (a) The purchase  price for said  Project  shall be ONE MILLION TWO
HUNDRED  EIGHTY-FIVE  THOUSAND  NINE  HUNDRED  FIFTY-FIVE  DOLLARS  AND NO CENTS
($1,285,955.00);  plus (1) any other sums or expenses of any type in  connection
with said  property  which have or had  accrued to the account of Lessee or were
otherwise  properly  payable by Lessee  according to the terms of this Lease but
were for any reason paid by Lessor;  plus (2) the total of all reasonable  costs
and expenses incurred or to be incurred by Lessor in the closing of such sale to
Lessee, excluding Lessor's legal fees, but including but not limited to the cost
of all title examinations and title insurance and other reasonable and necessary
closing  expenses.  Said total sum,  determined  as provided in this  Paragraph,
shall be paid in full and in cash or by  cashier's  check on the date of closing
of said purchase.

             (b) This  option  shall be in  effect  for the term of this  Lease,
including any renewal or extension thereof, and for one month thereafter. Notice
of election by Lessee to exercise  this option shall be in writing  delivered or
mailed as provided in Paragraph 8 hereof so to reach Lessor prior to the time of
expiration  of this  option.  As long as notice of  exercise  is given  prior to
expiration of the option, closing may occur after said expiration.

             (c) In the event this  option is so  exercised  by  Lessee,  Lessor
shall,  within thirty (30) days  thereafter,  provide to Lessee a commitment for
the issuance of title insurance,  certified to the date of Lessee's said notice,
showing  marketable  title to the premises to be vested in Lessor,  according to
the Title Examination Standards of the Iowa Bar, free and clear of all liens and
encumbrances of record,  except any encumbrances  which may be satisfied in full
by  Lessor  on or  before  the  date of  closing,  and  except  for the  special
exceptions,  if any, noted in Paragraph 1 of this Lease, and except for any lien
or encumbrance placed or suffered to be placed upon the premises by Lessee after
the date of this Lease,  and except for any other lien or encumbrance  otherwise
permitted or required  according to the terms of this Lease,  and except for the
lien for any taxes thereon which may attach or may have attached  after the date
of this Lease.  Lessee  shall  thereafter  have a period of fifteen (15) days to
examine said  commitment  and to  determine if defects are noted  therein in the
title of  Lessor.  If  defects  are found to exist in the title of Lessor  which
prevent absolute compliance with the requirements of this Paragraph, then Lessor
shall at Lessor's  expense  obtain the removal or  correction  of any such noted
defect,  if the same can be done  within six  months  after  being so noted.  If
defects of title are noted which are not capable of correction or removal within
such six month  period,  then  Lessee  shall  have the  option of  avoiding  the
obligation to purchase,  or of completing  the purchase of said  premises,  with
reduction in the price  therefore by an amount  sufficient to remedy such defect
in title or to  compensate  Lessee for the  reduction  in value of the  premises
attributable to such defect, as Lessee may determine.

             (d) The property  shall be conveyed by special  corporate  warranty
deed, properly executed and acknowledged by officials of Lessor and delivered to
Lessee, free and clear of all liens and encumbrances except as provided herein.

             (e) In the event of exercise of this option by Lessee, the sale and
conveyance  of said  property  shall be closed at the  office of Lessor in Cedar
Falls, Iowa, on the tenth business day immediately  following  expiration of the
time  granted  to Lessee for  examination  of said  commitment,  or on the tenth
business day  immediately  following the correction of noted defects of title by
Lessor,  or  upon  the  tenth  business  day  immediately   following   Lessee's
notification  to Lessor or  Lessee's  intention  to waive any noted  defects  in
title,  as the case may be. At the time of closing,  all papers,  documents  and
final payments  provided herein shall be exchanged  between the parties.  Lessee
shall at said  time be given  full and  absolute  possession  of said  premises,
without further  interference or claim of Lessor or any person claiming  through
Lessor.

             (f) If this  Option  is not  exercised  by  notice  in  writing  as
provided  above prior to midnight on the  appropriate  day of  expiration of the
same, said Option shall be of no further force or effect,  and the consideration
paid therefore  shall be retained by Lessor.  Proof of expiration of this Option
without  exercise  by Lessee may be made by  recording  of  Lessor's  affidavit,
reciting  the  failure of Lessee to exercise  said  Option and to  complete  the
purchase of said property in the manner provided herein and further reciting the
expiration of said Option,  and by recording of the receipt issued by the United
States  Postal  Service as proof of mailing by certified  mail of a copy of such
affidavit  at least ten days prior to the date of recording  the same.  Proof of
actual receipt of such affidavit by Lessee shall not be required.

covenant,  agreement,  obligation  or  provision  of  this  Lease,  or  for  the
applicable  provisions of the Special Terms and  Conditions or General Terms and
Conditions of said EDA Grant, on Lessee's part to be observed or performed,  and
such default  shall  continue for 60 days after Lessor has given Lessee  written
notice  specifying  such  default or such longer  period as shall be  reasonably
required to cure such default;  provided that (1) Lessee has commenced such cure
within said 60-day period,  and (2) Lessee  diligently  prosecutes  such cure to
completion; or

                  (3) Lessee  shall W admit in writing its  inability to pay its

                  (5) Violation of any  provision,  or commission or omission of
any act which causes or constitutes a violation of any provision, of the Special
Terms and Conditions or General Terms and  Conditions of said EDA Grant,  if not
timely cured to the satisfaction of the EDA.

             (b) If any Event of Default  specified  in  Paragraph  7(a)  hereof
shall have occurred and be  continuing,  then Lessor may, at Lessor's  election,
then or at any time thereafter,  and while such default shall continue, take any
one or more of the following actions:

                  (1) Cause all Lease  Payments  for the  remainder of the Lease
Term to become due and payable; or

                  (2) Give Lessee  written notice of intention to terminate this
Lease on a date  specified in such notice,  which date shall not be earlier than
30 days  after  such  notice is given,  and if all  defaults  have not then been
cured,  on the date so specified,  Lessee's  rights to possession of the Project
shall cease and this Lease shall thereupon be terminated, and Lessor may reenter
and take possession of the Project; or

                  (3) Without  terminating  this  Lease,  reenter the Project or
take possession  thereof pursuant to legal  proceedings or pursuant to any right
of  self-help or notice  provided  for by law, and having  elected to reenter or
take possession of the Project without  terminating this Lease, Lessor shall use
reasonable  diligence to relet the Project,  or parts thereof,  for such term or
terms and at such rental and upon such other provisions and conditions as Lessor
may deem  advisable,  with the  right to make  alterations  and  repairs  to the
Project,  and no such reentry or taking of  possessing  of the Project by Lessor
shall be construed as an election on Lessor's part to terminate this Lease,  and
no such reentry or taking of possession  by Lessor shall  relieve  Lessee of its
obligation to pay Lease  Payments or  Additional  Payments (at the time or times
provided  herein),  or of any of its other obligations  hereunder,  all of which
shall survive such reentry or taking of possession, and Lessee shall continue to
pay the Lease Payments specified herein until the end of the Lease Term, whether
or not the Project shall have been relet, less the net proceeds,  if any, of any
reletting of the Project after deducting of all of Lessor's  reasonable expenses
of or in  connection  with such  reletting,  including  without  limitation  all
repossession  costs,   brokerage  commissions,   legal  expenses,   expenses  of
employees, alteration costs and expenses of preparation for reletting.

Having elected to reenter or take possession of the Project without  terminating
this Lease,  Lessor may, by notice to Lessee given at any time thereafter  while
Lessee is in default in the payment of Lease  Payments or in the  performance of
any other  obligation  hereunder,  elect to terminate this Lease on a date to be
specified  in such  notice,  which date shall be not earlier  than 30 days after
reentry under Subparagraph (b)(3) above, and if all defaults shall not have then
been cured,  on the date so specified this Lease shall  thereupon be terminated.
If in accordance with any of the foregoing provisions of this Paragraph 7 Lessor
shall have the right to elect to reenter  and take  possession  of the  Project,
Lessor may enter and expel Lessee and those claiming through or under Lessee and
remove the property and effects of both either  (forcibly if necessary)  without
being guilty of any manner of trespass and without prejudice to any remedies for
arrears of rent or for  preceding  breach of covenant.  Lessor may take whatever
action at law or in equity  which may appear  necessary  or desirable to collect
rent then due and  thereafter  to become  due,  or to  enforce  performance  and
observance of any obligation, agreement or covenant of Lessee hereunder.

             Notwithstanding  any of the foregoing,  if Lessor elects to reenter
or take  possession of the Project and relet the same, in such reletting  Lessor
shall not adversely  affect any grant or loan made to Lessor,  the City of Cedar
Falls,  Iowa, by the United States Department of Commerce  Economic  Development
Administration, by Flood Relief Project Award No. 05-19-61126.

             (c)  Lessee   covenants   and  agrees  with  Lessor  that  Lessee's
obligations  hereunder  shall survive the  cancellation  and termination of this
Lease,  for any cause, and that Lessee shall continue to make the Lease Payments
required  hereunder and perform all other obligations  specified herein,  all at
the time or times provided herein;  provided,  however, that upon the payment of
all Lease Payments  required  hereunder,  Lessee's  obligations under this Lease
shall thereupon cease and terminate in full.

             (d) The rights and remedies reserved by Lessor and Lessee hereunder
and those  provided  by law shall be  construed  as  cumulative  and  continuing
rights. No one of them shall be exhausted by the exercise thereof on one or more
occasions.  Lessor and Lessee shall each be entitled to specific performance and
injunctive or other equitable relief for any breach or threatened  breach of any
of the provisions hereof,  notwithstanding availability of an adequate remedy at
law,  and each  party  hereby  waives  the right to raise  such  defense  in any
proceeding in equity.

             (e) No waiver of any breach of any  covenant  or  agreement  herein
contained  shall  operate  as a  waiver  of any  subsequent  breach  of the same
covenant  or  agreement  or as a waiver of any breach of any other  covenant  or
agreement,  and in case of a breach  by  Lessee of any  covenant,  agreement  or
undertaking by Lessee, Lessor may nevertheless accept from Lessee any payment or
payments  hereunder without in any way waiving Lessor's right to exercise any of
its rights and  remedies as provided  herein with respect to any such default or
defaults  of Lessee  which were in  existence  at the time when such  payment or
payments were accepted by Lessor.

             (f) In the  event  either  party  should  default  under any of the
provisions  hereof and the other party  should  employ  attorneys or incur other
expenses  for  the  collection  of the  Lease  Payments  or the  enforcement  of
performance of  any obligation or agreement on the part of the defaulting party,
the  defaulting  party  will  on  demand  pay to the  non-defaulting  party  the
reasonable fee of such attorneys and such other expenses so incurred.

             (g) If Lessee  shall fail to make any payment or to keep or perform
any of its  obligations  as provided  herein,  then Lessor may (but shall not be
obligated so to do) upon the continuance of such failure on Lessee's part for 60
days after notice of such failure is given Lessee by Lessor, and without waiving
or releasing  Lessee from any  obligation  hereunder,  as an additional  but not
exclusive remedy, make any such payment or perform any such obligation,  and all
sums so paid by Lessor and all necessary  incidental costs and expenses incurred
by Lessor in performing such obligations shall be deemed Additional Payments and
shall be paid be  Lessee  to Lessor  on  demand,  and if not so paid by  Lessee,
Lessor  shall have the same rights and remedies  provided for in Paragraph  7(b)
hereof in the case of default by Lessee in the payment of Lease Payments.

         8.  Administrative and Compliance Requirements.

             (a) The Lessee shall maintain books,  records,  documents and other
evidence  pertaining  to all costs and expenses  incurred and revenues  acquired
under this Agreement.

             (b) Audit and Inspection.  At any time during normal business hours
and as frequently as is deemed necessary, the Lessee shall make available to the
Lessor and the  Economic  Development  Administration  or their agents for their
examination,  all of its  records  pertaining  to all  matters  covered  by this
Agreement  and permit  these  agencies  to audit,  examine,  make  excerpts,  or
transcripts from such records, contract,  invoices, payrolls, personnel records,
conditions of employment, and all other matters covered by this Agreement.

             (c)  Retention  of Records.  All records in the  possession  of the
Lessee  pertaining  to this  Agreement  shall be retained by the  Borrower for a
period of three (3) years  beginning  with the date upon which this Agreement is
issued.  All records  shall be retained  beyond the  three-year  period if audit
findings have not been resolved within that period or if other disputes have not
been resolved.

             (d) Civil Rights Provision.  Lessee will comply with all applicable
Civil Rights provisions.

         9.  Mutual Covenants.  It is mutually agreed:

             (a) That any notice  provided  for herein may be given to the party
entitled thereto by personal service or by certified mail addressed as follows:

           To Lessor:                         To Lessee:

The following  factors could affect the Company's actual results,  including its
revenues,  expenses  and net  income,  and could  cause them to differ  from any
forward-looking statements made by or on behalf of the Company:

      The Company competes with a large number of other  agricultural  equipment
     manufacturers  and  suppliers  who  distribute   sprayers,   liquid  manure
     equipment, grain handling equipment and related parts. Although the Company
     believes that its products are  sufficiently  different from other products
     to enable it to establish and maintain a market for such products,  many of
     the Company's  principal  competitors  are larger than the Company and have
     substantial resources.  There can be no assurance that competitors will not
     be able to take  actions,  including  developing  new  products or offering
     reduced pricing, which could materially adversely affect the sales revenues
     of the Company.

      The Company has  warranted  the products it  manufactures  to be free from
     defects in  material  and  workmanship  under  normal use and service for a
     period  ranging from twelve to  twenty-four  months after date of purchase.
     Although  the Company  carries  product  liability  insurance  and casualty
     insurance  customary for  manufacturing  operations of its type,  there are
     certain  types  of  losses  which  are  uninsurable  or  not   economically
     insurable. There can be no guaranty against uninsured losses of any kind.

      The  continued  success of the  Company  will  depend upon the efforts and
     abilities  of certain key officers and  employees,  particularly  Steven R.
     Lind,  its  President  and Chief  Executive  Officer.  The Company could be
     adversely  affected if for any reason such officers and employees should no
     longer be active in the Company's operations. Steven R. Lind, President and
     Chief  Executive  Officer of the Company,  has entered  into an  employment
     agreement with the Company.

      The Company's executive officers and directors as a group beneficially own
     approximately 39% of the outstanding  shares of the Company's common stock.
     Accordingly,  these officers and directors  acting  together have effective
     voting  control  of  the  Company,  including  the  election  of all of the
     Company's directors and on any other matter being voted on by the Company's
     shareholders. There are no provisions for cumulative voting by stockholders
     in the  Company's  Articles  of  Incorporation.  These  facts  may  tend to
     discourage attempts to acquire control of the Company by persons other than
     those holders.
