include in such notice the manner and basis for such calculation. Buyer's
determination of the Asset Surplus or the Asset Shortfall shall be final,
binding and conclusive in the absence of fraud, bad faith and manifest error;
provided that accounts receivable over ninety days will not be considered assets
for purposes of this section 2.1.2.

            2.2 Payments.

                2.2.1 At Closing. On the Closing Date, Buyer shall pay the
Initial Purchase Price to Seller by check or wire transfer in accordance with
such written instructions as Seller may furnish to Buyer at least three business
days prior to the Closing Date, minus $200,000 (the "Payables Holdback"), which
will be held back from Purchase Price to pay trade accounts payable or debts
that (a) are set forth in Schedule 5.1.31 and are not paid by Seller within

                2.2.3 Payables Holdback. If, within ninety days after the
Closing Date (the "Holdback Period"), Buyer shall determine that Seller owes any
amount as a trade account payable or debt accrued prior to the Closing Date and
not shown on Schedule 5.1.31, or shown on Schedule 5.1.31 but not paid in full

Holdback, to the extent thereof. If any portion of the Payables Holdback shall
not have been so paid on or before the expiration of the Holdback Period, Seller
shall promptly pay such portion to Buyer, without interest; provided that Buyer
shall have the right to offset against such portion any other amount owing by
Seller to Buyer hereunder or otherwise.

well as all registrations and pending applications for registration of any of
the foregoing in any jurisdiction, and including each license, sublicense or
other contract relating thereto. Seller owns absolutely and exclusively all of
the Intellectual Property used or useful in Seller's business free and clear of
any Lien. The Shareholders own absolutely and exclusively all of the Shareholder
Patent Rights free and clear of any Lien. Seller and the Shareholders have fully
disclosed to Buyer all material information regarding the Intellectual Property,
all of which is listed and described on Schedule 5.1.13 attached hereto.

                    (b) Schedule 5.1.13 sets forth a complete and correct list
and description of all of the following Intellectual Property owned by any of
Seller, the Shareholders and affiliates of the Shareholders and a corresponding
list of each jurisdiction in which a patent or registration for such item has
been issued or in which an application has been filed therefor in the name of
Seller, the Shareholders or affiliates of the Shareholders: (i) letters patent
and patent applications, (ii) trademarks, service marks and trade names, and
(iii) copyrights. Each item set forth on Schedule 5.1.13 that is registered is
registered in the name and for the exclusive benefit of Seller, the Shareholders
or affiliates of the Shareholders.

                    (c) Seller has sole and exclusive rights to, and no other
person or entity has any claim of ownership, whether joint or individual, with
respect to, the Intellectual Property. The Shareholders have sole and exclusive
rights to and no other person or entity has any claim of ownership, whether

subsisting and in full force and effect and has been duly prosecuted, registered
and maintained by


                                       18
   19

Seller, the Shareholders or affiliates of the Shareholders in each jurisdiction
listed. No pending application for a patent or for registration of a trademark
has been rejected, suspended, made a subject of an office action or other
challenge by the agency with which such application has been filed or by any
third party, except as disclosed in Schedule 5.1.13. No patent has been claimed
or adjudicated to be invalid or unenforceable as a whole or in part, no
trademark or service mark has been the subject of any claim of abandonment or
otherwise challenged as invalid and no copyright has been invalidated or alleged
to be in the public domain. No patent or registration is subject to any current
tax, maintenance fee or renewal fee which has not been paid. All trademarks,
service marks and trade names set forth on Schedule 5.1.13 have been used
continuously by Seller since adoption by Seller.

                    (d) All of the Trade Secrets are valid and protectable, are
not publicly known and have not been disclosed or otherwise made available to
any person except pursuant to a written confidentiality agreement. Seller has
taken all reasonable and appropriate steps to protect and preserve all of the
Trade Secrets and all other Intellectual Property that is not otherwise
protected by patents or by copyright registrations. Each item of the Trade
Secrets qualifies as a "trade secret" under the Uniform Trade Secrets Act as
enacted as part of the California Civil Code. Seller does not possess and has
not used in its business any confidential information or trade secrets owned by
any person other than Seller except in strict compliance with the terms and
conditions of a valid and enforceable agreement between Seller and the owner or
owners of such trade secret or confidential information.

                    (e) Seller owns or is licensed or otherwise possesses
legally enforceable rights to use all Intellectual Property that is used or
useful in the business of Seller. No license, consent or other authorization is
required from any third party with respect to any Intellectual Property used or
useful in the business of Seller or, if so required, each such license or
consent has been obtained, is valid and enforceable in accordance with its terms
and is in full force and effect and is not the subject of any notice of
termination or nonrenewal, and there is no default or alleged or threatened
default with respect to any such license or consent.

                    (f) Seller's possession and use of the Intellectual Property
does not conflict with, infringe, violate, interfere with or constitute a
misappropriation of any right, title, interest or goodwill of any other person.
The Shareholders' and their affiliates' possession and use of the Shareholder
Patent Rights does not conflict with, infringe, violate, interfere with or
constitute a misappropriation of any right, title, interest or goodwill of any
other person. None of Seller and the Shareholders possesses any information or
is otherwise aware of any basis for any claim against any of Seller and the
Shareholders with respect to any infringement, misappropriation or other misuse
of any intellectual property of any third party. None of Seller, the
Shareholders and affiliates of the Shareholders has infringed, misappropriated
or misused or is now infringing, misappropriating or misusing any intellectual
property belonging to any other person.

                5.1.14 Tax Returns and Payments. Seller has filed all tax and
information returns and reports required by law to be filed by Seller, including
those with respect to receipts, income, sales, use, value added, ad valorem,

returns are proper and all taxes shown to be due and all additional assessments
and charges on Seller or on or measured by properties, assets, receipts, income,
sales


                                       19
   20

the books of Seller are reasonable and substantially adequate in amount. Seller
has not received any notice of assessment or proposed assessment of any United
States, state, municipal or other tax on or measured by income, receipts or
sales, nor to the best of Seller's and the Shareholders' knowledge, is there any
basis for any additional assessment of any such tax.

                5.1.15 Litigation. None of Seller and the Shareholders is a
party to any pending, and neither Seller nor any of the Shareholders has any
notice or knowledge of any threatened or any knowledge of any basis for any,
action, suit, proceeding or investigation, at law or in equity or otherwise, in,
before or by any court or arbitrator or any governmental board, commission,
agency, department or officer, in which an adverse determination could have any
material adverse effect on Seller or its business, operations or financial
condition or on any of the Assets.

any capacity) to any share in the proceeds, earnings or profits of Seller or its
business or the Assets or of any department, division or other unit of Seller or
its business, and Seller has no pension or retirement income plan, contract,
agreement or commitment in force for the benefit of any of its employees or
consultants, the obligations under which will not at the Closing Date have been

   21

agent (exclusive or otherwise) of any of its employees, except only for such

performed and discharged by Seller on or prior to the Closing Date.

                5.1.20 Other Interested Parties. None of Seller and the

commitment for the purchase or for the sale of any properties or assets of any
nature, except only such as have been made in the ordinary course of business.

                5.1.22 Insurance. All of the tangible Assets are insured to
their full replacement value with financially sound and reputable insurers.
Schedule 5.1.22 attached hereto contains a true and complete list and
description of all insurance policies of which Seller is the owner or
beneficiary.

                5.1.23 Condition of Assets. All of the tangible Assets are
accepted "as is" after acceptance on final inspection in good operating
condition and repair and in compliance with all applicable laws and regulations.
The use and operation of the Assets is in full compliance with applicable

ordinary course of business, will at the Closing Date represent legal, valid and
binding obligations due to Seller, and will at the Closing Date be collectible
in the ordinary course of business in the full recorded amounts thereof (except
only for any amount thereof for which reserves have been established on Seller's
balance sheet as of June 30, 2000). The Inventory is in good and merchantable
condition, reasonably in balance and currently of a usable and saleable quality
in the ordinary course of Seller's business. The Inventory is valued on Seller's
financial statements at the lower of cost or net realizable value, with cost
being determined on a consistent basis.

normal use and operation of the Assets and Seller's business and to insure
vehicular and pedestrian ingress to and egress from the premises where the
Assets are located.

                5.1.26 Additions. Seller is not a party to any contract,
agreement or commitment for any additions, repairs or improvements to any Assets
for which payment has not been made in full.

                5.1.28 Compliance with Laws. Each of Seller and the Shareholders
has complied with, and is not in violation of or default under, any laws, rules,
regulations, orders or decrees applicable to Seller or any of the Assets. To the

hereunder of the Assets to Buyer will include all rights necessary to ensure
compliance with all governmental statutes, laws, rules and regulations, and (b)
since December 31, 1999, no law, code, regulation or ordinance has been adopted

which would, if adopted or enacted, materially and adversely affect such
business as now conducted.

                5.1.29 Buyer's Use. None of Seller and the Shareholders has any
knowledge of any plan, study or effort of ICBO or any other code approval agency
or any governmental authority that would materially affect the business of
Seller or the use of the Assets, or any portion thereof, for their intended
uses, or of any intended public improvements that could result in any charge
being levied against, or any Lien assessed on, Seller or its business or any of
the Assets. None of Seller and the Shareholders has any notice or knowledge of
any facts that would adversely affect Buyer's usage and operation of the Assets
after the closing hereunder in the manner in which the Assets are now used and
operated by Seller.

                5.1.30 Environmental Matters.

and any other property owned or leased by Seller ("Corporate Property") and, to
the knowledge


                                       22
   23


of Seller and the Shareholders, prior to the Seller's ownership or leasing of
such Corporate Property, no Hazardous Material, other than that allowed under
Environmental Laws, including, without limitation, RCRA, has been disposed of,
or otherwise released on any Corporate Property.

                        (3) During Seller's ownership or leasing of the

agencies to Seller, the Shareholders or their agents in response to or relating
to any of such Records, Notifications and Reports.

                        (6) As used in this Agreement, "Hazardous Material"
means the substances (i) defined as "Hazardous Waste" in 40 CFR 261, and
substances defined in any comparable state statute or regulation; (ii) any
substance the presence of which requires remediation pursuant to any
Environmental Laws; and (iii) any substance required to be disposed of in a
manner expressly prescribed by Environmental Laws.

5.1.30(b), the Corporation has not owned or leased any real property not
included in the Corporate Property having any underground storage tanks
containing petroleum products or wastes or other hazardous substances regulated

                        (4) a copy of each notice to or from a governmental body
or agency relating to the UST;

                        (5) other material records with regard to the UST,

failed to meet applicable standards and regulations for tightness or otherwise
and the extent of such failure, and any other operational or environmental
problems with regard to the UST, including, without limitation, spills, whether
in connection with delivery of materials to the UST, releases from the UST, soil
contamination or otherwise.

                    Except to the extent set forth on Schedule 5.1.30(b), the
Seller has complied with Environmental Laws regarding the installation, use,
testing, monitoring, operation and closure of each UST described on Schedule

now due or becoming due in the future. All of the Trade Payables were incurred

transactions.

                    5.1.32 Disclosure. Neither this Agreement nor the financial
statements delivered as provided in section 5.1.8 nor any exhibit or schedule
hereto nor any other certificate, instrument, document or information furnished
by Seller or any of the Shareholders to Buyer hereunder or in connection
herewith contains any untrue statement of a material fact or omits to state any
material fact necessary to make the statements contained therein or herein not
misleading. There is no fact which adversely affects or in the future may (so

herein or in an exhibit or schedule hereto or otherwise disclosed in writing to
Buyer.

   37


                                                                       EXHIBIT D

               OPINION OF COUNSEL FOR SELLER AND THE SHAREHOLDERS

        Capitalized terms used and not otherwise defined herein have the
meanings respectively ascribed to them in the Asset Purchase Agreement.

        (a) Seller is a corporation duly organized, validly existing and in good
standing under the laws of the State of Indiana. Seller is duly qualified to
conduct business and is in good standing as a foreign corporation under the laws
of each jurisdiction where, by virtue of its business conducted therein, it is
required to be so qualified, except where the failure to be so qualified will
not have any material adverse effect on Seller or its business, assets or
financial condition.

        (b) The authorized capital stock of Seller consists of 1,000 shares of
common stock, of which 1,000 shares have been duly and validly issued in
compliance with the securities laws of the State of Indiana and are outstanding,
fully paid, nonassessable and free of preemptive and similar rights.

        (c) Seller has all necessary power, authority and capacity to carry on
its business as now being conducted, to own its assets, to sell the Assets to
Buyer as contemplated by the Agreement, to execute and deliver the Agreement,
the Bill of Sale, the Patent Assignments and the Trademark Assignments
(collectively, the "Transaction Documents") and all certificates, instruments
and other documents contemplated thereby and to perform its obligations
thereunder, and all necessary action and other proceedings, including obtaining
all necessary waivers, approvals and consents from third parties and others,
required to be taken by any or all of Seller and the Shareholders to authorize
and carry out the Transaction Documents and the transactions thereunder have
been duly and properly taken or obtained.

        (d) The Transaction Documents and the instruments and documents of
transfer and conveyance of the Assets in connection therewith have been duly
executed and delivered by Seller and the Shareholders party thereto,
respectively, and constitute legal, valid and binding agreements of Seller and
the Shareholders, enforceable against them in accordance with their respective
terms, except as such enforceability may be limited by bankruptcy, insolvency,
reorganization, arrangement, moratorium or other similar laws relating to or
affecting the rights of creditors generally and except for limitations imposed
by general principles of equity on the availability of equitable remedies.

        (e) To the best of our knowledge and belief after reasonable inquiry,
Seller has, and at the closing on the Closing Date Buyer will acquire, good and
marketable title to all of the Assets, free and clear of all Liens, except Liens
in favor of Buyer.
