Agreement, at the Closing, Sellers will sell, transfer, convey and assign the

         2.2 Purchase Price.

         (a) The purchase price (the "Purchase Price") for the Parker Assets

($2,410,000), as adjusted by the Adjustment Amount (whether a positive or
negative amount), (y) the Accounts Receivable Amount, and (z) the amount of the
Current Liabilities, which Purchase Price shall be payable as follows:

         (i)    Two Million, Four Hundred Ten Thousand Dollars ($2,410,000) of
                the Purchase Price, as adjusted by the Estimated Adjustment
                Amount in accordance with Section 2.8, shall be payable at
                Closing by wire transfer of immediately available funds pursuant

                the amount estimated, then the Note delivered by Parker Sub at
                Closing will be replaced with a new note of like tenor in the
                principal amount of the Accounts Receivable Amount shown on the
                Closing Balance Sheet; which Note, in either case, will be
                unconditionally guaranteed by Top Air pursuant to the guaranty

Acquisition Statement, for Buyers and Sellers and (ii) all tax returns. Buyers
and Sellers shall file Form 8594 prepared in accordance with this Section with
its federal income tax return for its tax period which includes the Closing

following any adjustments to the Purchase Price pursuant to the terms hereof.

         2.3 Assumption of Assumed Liabilities.

         (a) From and after the Closing, Parker Sub shall assume, pay, perform,
fulfill and discharge those obligations of Parker Industries (i) that are
required to be performed under those contracts, leases of Leased Equipment and

a Current Liability, to the extent of such accrual (including without limitation
properly accrued vacation pay); and (iii) for product warranty claims now

         (b) Except for the Assumed Liabilities, in no event shall Buyers assume
or incur any liability or obligation hereunder of Sellers' or any of their
subsidiaries or Affiliates (collectively, the "Retained Liabilities"). Without

         2.7 Taxes. Except to the extent expressly provided for hereunder,
Sellers shall be responsible for all taxes with respect to the Parker Assets
that accrue prior to the Closing Date and Buyers shall be responsible for all
such taxes that accrue from and after the Closing Date. All real estate and
other transfer taxes which are payable or arise as a result of this Agreement or
the Closing pursuant to this Agreement shall be paid by Sellers and Buyers
together in equal amounts notwithstanding how such taxes are imposed by statute.

         2.8 Estimated Adjustment Amount.

         (a) On or before the fifth business day preceding the Closing Date,
Sellers shall provide Buyers, in writing, their estimate of the Net Asset Value
of Parker Industries as of the Closing Date, for purposes of estimating the
Adjustment Amount (the "Estimated Adjustment Amount") together with the balance
sheet and income statement of Parker Industries for the then most-recently
completed calendar month and such other information in support of such estimated
Net Asset Value. Buyers shall notify Sellers in writing within three business
days of its receipt of such estimate as to whether or not Buyers agree with
Sellers' estimate and if Buyers disagree with such estimate, the parties will
negotiate in good faith in an effort to agree upon an estimated Net Asset Value.
If the parties can agree upon an estimated Net Asset Value, then the Adjustment
Amount shall be calculated based upon such estimated Net Asset Value and the
amount thus calculated shall be and constitute the Estimated Adjustment Amount
for purposes of Section 2.2(a)(i). If the parties are unable to agree as to an
estimated Net Asset Value, then, for purposes of this agreement, the Sellers'
estimate shall be used to determine the Estimated Adjustment Amount. As soon as
practicable, but in any event within thirty (30) days after the Closing Date,
Sellers shall prepare and deliver to Buyers the Closing Balance Sheet, which
Closing Balance Sheet shall be prepared in the same manner as the balance sheet
included in the Fiscal 1998 Financial Statements and in accordance with GAAP,

                                       10
<PAGE>

but without an audit report or footnotes. Inventory shall be valued in
accordance with the foregoing and based upon a joint physical inventory taken on
the Closing Date by Buyers, Sellers, and their respective accountants. To the
extent that the Adjustment Amount derived from the Net Asset Value shown on the
Closing Balance Sheet is more or less than the Estimated Adjustment Amount,
Buyers shall pay to Sellers or Sellers shall pay to Buyers, as the case may be,
the amount of such difference on a dollar-for-dollar basis and the Purchase
Price shall be deemed to be increased or decreased, as the case may be,
accordingly. Any amount due under this Section 2.8(a) shall be due within five
(5) business days of the completion of the Closing Balance Sheet and the
resolution of any disputes with respect thereto pursuant to Section 2.8(b).
Interest shall accrue from the Closing Date on the payment amount due at the
rate charged by Mercantile Bank on the Closing Date as its base rate on the
Closing Date, and shall be payable simultaneously with the Purchase Price
adjustment under this Section 2.8(a).

         (b) Buyers and their accountants shall be entitled to observe and
consult with Sellers and their accountants in connection with the preparation of
the Closing Balance Sheet. Sellers' independent auditing firm shall make its
workpapers available to Buyers and their accountants. If Buyers object to the
Closing Balance Sheet, they must notify Sellers in writing of each adjustment
item, specifying the amount thereof and setting forth, in reasonable detail, the
basis for such adjustment, no later than 20 days after Buyers' receipt of the
Closing Balance Sheet. If Buyers do not so notify Sellers, the Closing Balance
Sheet, as prepared by Sellers, shall be final, binding and conclusive on the
parties. In the event of a dispute with respect to a proposed adjustment, Buyers
and Sellers shall attempt to reconcile their differences, and any resolution by
them as to any disputed amounts shall be final, binding and conclusive on the
parties. If Buyers and Sellers are unable to resolve such dispute(s) within 20
days after Buyers deliver written notice thereof, Buyers or Sellers may submit
the items remaining in dispute for resolution to an independent accounting firm
of national reputation mutually appointed by Buyers and Sellers, or if the
parties are unable to agree upon such accounting firm, then Arthur Andersen (Des
Moines office) shall be selected (the "Independent Accounting Firm"). The
Independent Accounting Firm shall resolve any such dispute by sole reference to
Sellers' historic practice of maintaining the books and records of the Business;
provided, however, that all issues of materiality with regard to the Closing
Balance Sheet shall be determined with reference to Parker Industries as a stand
alone entity, conducting the Business, and not with reference to Owosso on a
consolidated basis. The Independent Accounting Firm shall not apply or be bound
by any other policies, practices or principles. The Independent Accounting Firm
shall, within 20 days after submission, determine and report in writing to the
parties upon such disputed items, and such report shall be final, binding and
conclusive on the parties hereto. Buyers and Sellers shall share equally the
fees and charges of the Independent Accounting Firm. The parties acknowledge and
agree that no adjustments shall be made to the accumulated depreciation and
inventory line items reflected on the Closing Balance Sheet so long as such line
items are determined in accordance with Sellers' current accounting procedures,
consistently applied. The parties also acknowledge and agree that appropriate
adjustments will be made on the Closing Balance Sheet for cash discounts on
receivables paid by or credited to customers of Parker postmarked no later than
March 5, 1999, under the Sellers' "8% Prepayment Program" so that Buyers are not
adversely affected by any such discounts.

         2.9 Real Property. The parties hereto acknowledge the proposed sale by
Sellers of the Real Property (including the Facilities) to the Authority,
subject to the lease thereof by the Authority to Buyers (the "Authority
Transaction"). The Real Property (and the Facilities thereon) shall therefore be
excluded from the Parker Assets being acquired by Buyers hereunder.
Notwithstanding anything in this Agreement to the contrary, Sellers shall not be
responsible for any of the costs of the Authority Transaction.

                                   SECTION 3.

fact or condition require any change in a Disclosure Schedule hereto if the
Disclosure Schedule were dated the date of the occurrence or discovery of any
such fact or condition, Sellers will promptly deliver to Buyers a supplement to

change in a Disclosure Schedule hereto if the Disclosure Schedule were dated the
date of the occurrence or discovery of any such fact or condition, Buyers prior
to Closing deliver to Sellers a supplement to such Schedule specifying such
change. During the same period, Buyers will promptly notify Sellers of the

              (ii) any Breach of any representation or warranty made by Sellers

Representatives, partners, stockholders, controlling person and Affiliates, the
amount of any Expenses and Damages arising, directly or indirectly, from or in

in this Agreement, the Disclosure Schedules prepared by Buyers, or in any

of a representation or warranty made by Buyers in this Agreement together with
any supplement to the Disclosure Schedule prepared by Buyers as if such
representation or warranty were made on and as of the Closing Date; (c) any
Breach of any covenants or obligation of Buyers in this Agreement; and (d) any
claim relating to the Assumed Liabilities.

         12.4 Procedure for Indemnification--Third Party Claims.

         (a) Promptly after receipt by an indemnified party under Section 12.2
or 12.3 of notice of the commencement of any Proceeding against it, such
indemnified party will, if a claim is to be made against an indemnifying party
under such Section, give notice to the indemnifying party of the commencement of
such claim, but the failure to notify the indemnifying party will not relieve
the indemnifying party of any liability that it may have to any indemnified
party, except to the extent that the indemnifying party demonstrates that the
defense of such action is prejudiced by the indemnifying party's failure to give
such notice.

         (b) If any Proceeding referred to in Section 12.4(a) is brought against
an indemnified party and it gives notice to the indemnifying party of the
commencement of such Proceeding, the indemnifying party will be entitled to
participate in such Proceeding and, to the extent that it wishes (unless (i) the
indemnifying party is also a party to such Proceeding and the indemnified party
determines in good faith that joint representation would be inappropriate, (ii)
the indemnifying party fails to provide reasonable assurance to the indemnified
party of its financial capacity to defend such Proceeding and provide
indemnification with respect to such Proceeding, or (iii) the outcome of the
Proceeding will have a continuing effect the indemnified party), to assume the
defense of such Proceeding with counsel satisfactory to the indemnified party
and, after notice from the indemnifying party to the indemnified party of its
election to assume the defense of such Proceeding, the indemnifying party will
not, as long as it diligently conducts such defense, be liable to the
indemnified party under this Section 12.4(c)(b) for any fees of other counsel or
any other expenses with respect to the defense of such Proceeding, in each case
subsequently incurred by the indemnified party in connection with the defense of
such Proceeding, other than reasonable costs of investigation. If the
indemnifying party assumes the defense of a Proceeding, (i) it will be
conclusively established for purposes of this Agreement that the claims made in
that Proceeding are within the scope of and subject to indemnification; (ii) no
compromise or settlement of such claims may be effected by the indemnifying
party without the indemnified party's consent unless (A) there is no finding or
admission of any violation of Legal Requirements or any violation of the rights
of any Person and no effect on any other claims that may be made against the
indemnified party, and (B) the sole relief provided is monetary Damages that are
paid in full by the indemnifying party; and (iii) the indemnified party will
have no liability with respect to any compromise or settlement of such claims
effected without its Consent. If notice is given to an indemnifying party of the
commencement of any Proceeding and the indemnifying party does not, within ten
days after the indemnified party's notice is given, give notice to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will be bound by any determination made in such Proceeding or
any compromise or settlement effected by the indemnified party.

                                       30
<PAGE>

         (c) Notwithstanding the foregoing, if an indemnified party determines
in good faith that there is a reasonable probability that a Proceeding may
adversely affect it or its affiliates other than as a result of monetary Damages
for which it would be entitled to indemnification under this Agreement, the
indemnified party may, by notice to the indemnifying party, assume the exclusive
right to defend, compromise, or settle such Proceeding, but the indemnifying
party will not be bound by any determination of a Proceeding so defended or any
compromise or settlement effected without its Consent (which may not be
unreasonably withheld).

         (d) Sellers hereby consent to the non-exclusive jurisdiction of any
state or federal court situated in Iowa in which a Proceeding is brought against
any Indemnified Person for purposes of any claim that an Indemnified Person may
have under this Agreement with respect to such Proceeding or the matters alleged
therein, and agree that process may be served on Sellers and their shareholders
with respect to such a claim anywhere in the world.

         12.5 Procedure for Indemnification--Other Claims. A claim for
indemnification for any matter not involving a third-party claim may be asserted
by notice to the party from whom indemnification is sought.

         12.6 Legal Fees and Expenses. Except as expressly set forth in this
Section 12, each party shall pay its own legal expenses with respect to all
matters arising under this Section 12.

         12.7 Limit of Indemnification. Notwithstanding any provision in this
Section 12 to the contrary, no claim for indemnification may be made unless and
until the aggregate of all indemnifiable claims suffered by the potential
indemnified parties exceeds $100,000 and thereafter only for amounts in excess
of said $100,000 threshold; provided, however, that Sellers' obligation to
indemnify with respect to breaches of its representations, warranties or
agreements with respect to the Excluded Basket Items shall not be subject to
said $100,000 limitation. The indemnifiable claims required to be paid by
Sellers pursuant to this Section 12 shall in no event exceed the amount of the
Purchase Price. Indemnification pursuant to this Section 12 shall be the sole
remedy to any party hereto for Breaches by another party prior to Closing of the
representation and warranties contained in this Agreement.

         12.8 Right of Set-Off. Buyers shall have the right to set-off against
its payment obligations under the Note made and delivered pursuant to Section
2.2(a)(ii) for any amount Buyers may be entitled in accordance with the
provisions of this Section 12 or otherwise pursuant to this Agreement, provided,
however, any amounts proposed by Buyers to be set-off pursuant to this Section
12.8 and contested by Sellers shall be paid when due into an interest-bearing
escrow account with instructions to disburse such funds (and accrued interest
thereon) to Buyers if Buyers prevail in the subject dispute, to Sellers if
Seller prevail in the subject dispute, and pursuant to the joint instructions of
Buyers and Sellers if an accommodation is attained between Buyers and Sellers.

                                   ARBITRATION

         13.1 Arbitration. Any dispute arising under this Agreement shall be
settled by arbitration in Chicago, Illinois, before a single arbitrator pursuant
to the rules of the American Arbitration Association. Arbitration may be
commenced at any time by any party hereto giving written notice to each party to
a dispute that such dispute has been referred to arbitration. The arbitrator
shall be selected by the joint agreement of Buyer and Seller, but if they do not
so agree within twenty (20) days after the date of the notice referred to above,
the selection shall be made pursuant to the rules from the panels of arbitrators
maintained by such Association. Any award rendered by the arbitrator shall be
conclusive and binding upon the parties hereof; provided, however, that any such
award shall be accompanied by a written opinion of the arbitrator giving the
reasons for the award. This provision for the arbitration shall be specifically
enforceable by the parties and the decision of the arbitrator in accordance
herewith shall be final and binding and there shall be no right of appeal
therefrom. The submission of any dispute to arbitration shall not relieve the
parties hereto from the respective obligations under this Agreement that are not
the specific subject matter of such dispute.

                                  SECTION 14.
