their properties, or of any federal, state or local law, rule or
regulation, which conflicts with or in any way prevents or will be
violated by the execution, delivery or carrying out of the terms of
this Agreement, the consummation of the Transaction or the
Distribution, nor will such execution, delivery or consummation
constitute a default, or an event which with the giving of notice
or the passage of time, or both, would constitute a default, under
any of the foregoing, nor be the grounds for the suspension,
revocation, impairment, forfeiture, nonrenewal or termination of
any license, permit, franchise, certificate, consent or

respect to, any of the Transferred Assets, or (b) a complete or
partial withdrawal from any employer or multi-employer/employee

              ------                          -------------
personal or real property used by Clay Equipment in connection with

maintains (a) "all risk" insurance on the full fair market value of
all of the Assets and on its Business, covering property damage by

such policies of insurance shall be in form and substance

nor, to the knowledge of Clay Equipment any default or threatened
default by any other party thereto, existing with respect to any of
such agreements.  Clay Equipment has received no notice that any
party to any of such agreements intends to cancel or terminate any
of such agreements or to exercise or not exercise any options under

              ------------------------------

              (a)     No customer of Clay Equipment accounted for

                      -------------                -------------
       attached hereto is an accurate and complete list of all
       employee benefit plans ("Employee Benefit Plans") within the
       meaning of Section 3(3) of ERISA, whether or not any such
       Employee Benefit Plans are otherwise exempt from the
       provisions of ERISA, established, maintained or contributed to
       or by Clay Equipment or any of its subsidiaries (including,

                                    17
 23
       for this purpose and for the purpose of all of the
       representations in this Section 4.24, all employers (whether
       or not incorporated) which by reason of common control are
       treated together with Clay Equipment, any of its subsidiaries
       and/or Clay Holding as a single employer within the meaning of
       Section 414 of the Code.

              (b)     Status of Plans.  Neither Clay Holding nor any
                      ---------------
       of its subsidiaries maintain or contribute to any Employee
       Benefit Plan subject to ERISA which is not, or in the past has
       not been, in substantial compliance with ERISA, or which has
       incurred any accumulated funding deficiency within the meaning
       of Section 412 or Section 418B of the Code, or which has
       applied for or obtained a waiver from the Internal Revenue
       Service of any minimum funding requirement under Section 412
       of the Code.  Clay Equipment has not incurred any liability to
       the Pension Benefit Guaranty Corporation ("PBGC") in
       connection with any Employee Benefit Plan covering any
       employees of Clay Equipment or any such subsidiaries,
       including any liability under Section 4069 of ERISA and any
       penalty imposed under Section 4071 of ERISA, or ceased
       operations at any facility or have withdrawn from any such
       plan in a manner which could subject it to liability under
       Sections 4063, 4064 or 4068(f) of ERISA, and know of no facts
       or circumstances which might give rise to any liability of
       Clay Equipment or any of its subsidiaries to the PBGC under
       Title IV of ERISA which could reasonably be anticipated to
       result in any claims being made against Top Air by the PBGC.
       Neither Clay Equipment nor any of its subsidiaries have
       incurred any withdrawal liability (including any contingent or
       secondary withdrawal liability) within the meaning of Sections
       4201 and 4204 of ERISA, to any Employee Benefit Plan which is
       a "Multiemployer Plan" (as such term is defined in Section
       4001(a)(3) of ERISA), and no event has occurred, and there
       exists no condition or set of circumstances, which presents a
       risk of the occurrence of any withdrawal from or the
       partition, termination, reorganization or insolvency of any
       Multiemployer Plan which could result in any liability to a
       Multiemployer Plan.

              Clay Equipment does not maintain any Employee Benefit
       Plan which is a "Group Health Plan" (as such term is defined
       in Section 162(i)(3) of the Code) that has not been
       administered and operated in all material respects in
       compliance with the applicable requirements of Section 601 of
       ERISA and Section 162(k) of the Code and neither Clay
       Equipment nor any subsidiary are subject to any liability,
       including, but not limited to, additional contributions,
       fines, penalties or loss of tax deduction as a result of such
       administration and operation.  Neither Clay Holding nor any of
       its subsidiaries maintain any Employee Benefit Plan (whether
       qualified or nonqualified within the meaning of Section 401(a)

                                    18
 24
       of the Code) providing for retiree health and/or life benefits
       and having unfunded liabilities. Neither Clay Equipment nor
       any of its subsidiaries maintain any Employee Benefit Plan
       which is an "Employee Welfare Benefit Plan" (as such term is
       defined in Section 3(l) of ERISA) and have provided any
       benefit which is a "Disqualified Benefit" (as such term is
       defined in Section 4976(b) of the Code) for which an excise
       tax would be imposed.

              (c)     Contributions.  Full payment has been made of
                      -------------
       all amounts of which Clay Equipment is required to pay, under
       applicable law or under any Employee Benefit Plan or any
       agreement relating to any Employee Benefit Plan to which Clay
       Equipment is a party, to have paid as contributions thereto as
       of the last day of the most recent fiscal year of such
       Employee Benefit Plan ended prior to the date hereof.  Clay
       Equipment has made adequate provision for reserves to meet
       contributions that have not been made because they are not yet
       due under the term, of any Employee Benefit Plan or related
       agreements.  Benefits under all Employee Benefit Plans are as
       represented and have not been increased subsequent to the date
       as of which documents have been provided.

              (d)     Relationship of Accrued Benefits to Pension
                      -------------------------------------------
       Plan Assets.  As of the date of this Agreement (i) neither
       -----------
       Clay Equipment nor Clay Holding maintains any Employee Benefit
       Plans which are subject to Title IV of ERISA and which are
       "Single Employer Plans" (as such term is defined in Section
       4001(a)(15) of ERISA); and (ii) using actuarial assumptions
       and computation methods consistent with subpart 1 of subtitle
       E of Title IV of ERISA, the aggregate liabilities of Clay
       Equipment and its subsidiaries to all such Employee Benefit
       Plans which are Multiemployer Plans in the event of a complete
       withdrawal therefrom, as of the close of the most recent
       fiscal year of each Multiemployer Plan ended prior to the date
       hereof, would not exceed $50,000.  There has been no material
       change in the financial condition of any Multiemployer Plan or
       in any such actuarial assumption or computation method or in
       benefits under any Multiemployer Plan as a result of
       collective bargaining or otherwise since the close of each
       such fiscal year which, individually or in the aggregate,
       would materially increase such liability.
