There is no reason to expect any authority to assess any additional taxes on Ficklin for any period for which tax returns have been filed. There is no dispute or claim concerning any tax liability of Ficklin. The unpaid taxes of Ficklin did not, as of October 31, 1996, exceed the reserve for tax liabilities set forth on the balance sheet of Ficklin dated as of October 31, 1996, and did not exceed that reserve as adjusted for the passage of time through the date hereof in accordance with the past custom and practice of Ficklin in filing its tax returns. All monies required to be withheld by Ficklin from employees of Ficklin for income taxes, social security and other payroll taxes have been collected or withheld, and either paid to the respective governmental agencies, set aside in accounts for such purpose, or accrued, reserved against and entered upon the books of Ficklin. 8 Section 2.14 Employees; Employment Agreements.

There are no pending actions or other judicial or adversarial proceedings involving Ficklin concerning any of the intangible property and, to the best of Whalen's actual knowledge, there is no basis for any such action or proceeding; no such action or proceeding is threatened which, in either case, if adversely determined, would have a Material Adverse Effect on Ficklin.

Section 3.11 Litigation. There is no suit, action, arbitration, inquiry or legal, administrative, or other proceeding, or governmental investigation pending or, to the best of Top Air's actual knowledge, threatened, against or affecting Top Air which, if adversely determined, would be reasonably likely to have a Material Adverse Effect on Top Air or which questions or challenges the validity of this Agreement, or any action taken or to be taken by Top Air pursuant to this Agreement or in connection with the transactions contemplated hereby. Top Air is not subject to any order, writ, injunction, or decree of any federal, state, local, or foreign court, department, agency, or instrumentality which relates to Top Air's business, or which would prevent it from performing in accordance with the terms of this Agreement. Section 3.12 Title to Assets; Encumbrances. Except as set forth below or in Section 3.12 of the Disclosure Schedule, Top Air has title to the assets reflected in the Top Air Financials or necessary for the operation of the business of Top Air free and clear of all material Encumbrances. Section 3.13 Tax Returns. Top Air has filed all foreign, federal, state, county and local income, excise, withholding, property, sales, use, franchise and any other tax returns which are required to be filed and paid all taxes of any nature whatsoever which have become due (whether or not shown on any tax return) . No claim has ever been made by an authority in a jurisdiction where Top Air does not file a tax return that it is or may be subject to taxation by the jurisdiction. Top Air does not expect any authority to assess 13 any additional taxes for any period for which tax returns have been filed. There is no dispute or claim concerning any tax liability of Top Air. The unpaid taxes of Top Air did not, as of November 30, 1996, exceed the reserve for tax liabilities set forth on the unaudited balance sheet of Top Air dated as of November 30, 1996, and did not exceed that reserve as adjusted for the passage of time through the date hereof in accordance with the past custom and practice of Top Air in filing its tax returns. All monies required to be withheld by Top Air from employees of Top Air for income taxes, social security and other payroll taxes have been collected or withheld, and either paid to the respective governmental agencies, set aside in accounts for such purpose, or accrued, reserved against and entered upon the books of Top Air. Section 3.14 Employees; Employment Agreements. (a) Except as set forth in Section 3.14(a) of the Disclosure Schedule, there are no employment, management, consulting, deferred compensation, severance, stock option plans or arrangements, stock purchase plans or agreements, bonus or incentive plans or programs, life insurance, hospital or medical plans or coverages, or any other employee welfare plans, agreements, arrangements or commitments (other than normal payroll practices and policies concerning holidays, vacations and salary continuation during short absences for illness or other reasons), or other similar agreements or any union or collective bargaining agreements or any contracts or agreements with any employee or any labor organizations binding upon Top Air. (b) Except as set forth in Section 3.14(b) of the Disclosure Schedule, Top Air does not, and has never, maintained any employee benefit plan subject to Title IV of the Employee Retirement Income Security Act of 1974, as amended ("ERISA") for any employees of Top Air.

Section 3.15 Trademarks, Trade Names, etc. Top Air owns, or is licensed to use the intangible property required to permit the operation of Top Air's business as currently conducted. There are no pending actions or other judicial or adversarial proceedings involving Top Air concerning any of the intangible property and, to the best of Top Air's actual knowledge, there is no basis for any such action or proceeding; no such action or proceeding is threatened which, 14 in either case, if adversely determined, would have a Material Adverse Effect on Top Air. The use of each such item of intangible property required to permit the operation of Top Air's business as presently conducted does not conflict with, infringe upon, or violate any proprietary or other rights of any other person, which conflict, infringement or violation would, individually or in the aggregate, have a Material Adverse Effect on Top Air. Section 3.16 Disclosure. No representation or warranty by Top Air contained in this Agreement and no statement of Top Air contained in the Disclosure Schedules contains any untrue statement of a material fact, or omits to state any material fact necessary, in light of the circumstances under which it was made, in order to make the statements herein or therein not misleading.

Such indemnification shall be Whalen's sole and exclusive remedy. Section 5.3 Indemnification Procedure. Promptly after an indemnified party becomes aware of any claim, demand, action, proceeding, event, or condition with respect to which a claim for indemnification may be made pursuant to this Article, such indemnified party shall, if a claim in respect thereof is to be made against any party, give written notice to the latter of the nature of the matter for which a right to indemnification is claimed (an "Indemnification Claim"); provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of any obligations, except to the extent (and only to the extent) the indemnifying party is materially prejudiced thereby. In case any such Indemnification Claim involves a claim, demand, action, or proceeding by a third party (a "Third Party Claim"), the indemnifying party shall be entitled to assume the defense thereof, jointly with any other indemnifying party similarly notified, with counsel reasonably satisfactory to such indemnified party, such defense to be conducted at the expense of the indemnifying party.

Notwithstanding any of the foregoing to the contrary, the indemnified party will be entitled to select its own counsel and assume the defense of any Third Party Claim action if the indemnifying party fails to select counsel reasonably satisfactory to the indemnified party or fails to prosecute the defense, the expenses of such defense to be paid by the indemnifying party.

An Indemnification Claim (other than any Indemnification Claim involving a Third Party Claim, which shall be payable as provided in Section 5.3 above) shall be payable under Section 5.1 above by Whalen or under Section 5.2 above by Top Air, as applicable, when (i) there is a mutual agreement between the indemnified party and the indemnifying party as to the indemnifying party's liability for such Indemnification Claim and the amount of such liability, or (ii) a final judgment is rendered by a court of competent jurisdiction (and such judgment is not stayed for a period of 60 days) with respect to the indemnifying party's liability for the Indemnification Claim and the amount of such liability. The amount which an indemnifying party is required to pay to, for or on behalf of any indemnified party pursuant to Article VII shall be adjusted (including, without limitation, retroactively) (i) by any insurance proceeds actually recovered by such indemnified party in reduction of the indemnifiable loss (the "Indemnifiable Loss"); (ii) to take account of any tax benefit realized as a result of any Indemnifiable Loss; and (iii) by the amount of any now existing reserves relating to such claim.
