     3.   REPRESENTATIONS.

     (a)  World Wide represents and warrants to Saturn now and as of the Closing
date that:

          (i)  The sale and transfer of the Stock to Saturn was duly authorized
               and does not violate any contract or agreement to which World
               Wide is a party or is bound or any requirement of law applicable
               to World Wide, and all approvals required to transfer the Stock
               to Saturn have been (or will be by Closing) obtained.

          (ii) World Wide is the sole owner, beneficially and of record, of the
               Stock, and has good and marketable title to the Stock, free and
               clear of any and all liens, charges, security interests, pledges,
               restrictions, claims and encumbrances of any kind.

     (b)  Saturn represents and warrants to World Wide now and as of the Closing
date that:

          (i)  The purchase of the Stock by Saturn was duly authorized and does
               not violate any contract or agreement to which Saturn is a party
               or is bound or any requirement of law applicable to Saturn, and
               all approvals required to purchase the Stock have been (or will
               be by Closing) obtained.
          (ii) Saturn has provided to World Wide copies of the financial
               information listed on Attachment 3 attached hereto (collectively,
               the "Financial Information"). To the best of Saturn's knowledge,
               the Financial Information does not contain any untrue statement

               therein not misleading as of the date prepared and in light of
               the circumstances in which they were made. To the best of
               Saturn's knowledge, Saturn has disclosed to World Wide all
               material transactions which are currently active and for which

               information of which the President and Chief Financial Officer of
               Saturn were aware at the time the Forecasts were prepared. World
               Wide acknowledges and agrees that Saturn is not making any
               representation or warranty regarding any forward-looking
               statements provided to World Wide, including those that
               constitute part of the Financial Information (collectively, the
               "Forecasts"), or that Saturn will achieve the numbers set forth
               in the Forecasts. World Wide further acknowledges and agrees that
               such Forecasts are subject to uncertainty, unknown or changed
               opportunities, changed circumstances and other factors which
               could affect the Forecasts and cause actual results to differ
               materially (beneficially or

                                       2
<PAGE>   3

               2002. World Wide acknowledges and agrees that these percentages
               are Forecasts as used in this paragraph and that the disclaimers
               set forth in this paragraph apply to these percentages.
          (iii)Saturn represents and warrants that Saturn and its subsidiaries,

               the United States Internal Revenue Code during the applicable
               period specified in Section 897(c)(l)(A)(ii) thereof. Saturn
               shall indemnify and hold World Wide harmless from and against any
               assessment, penalty or interest charge arising out of or
               resulting from any breach of the representation made in the
               previous sentence.

     4. RELEASE AND WAIVER OF WORLD WIDE. In consideration of the purchase price
to be paid for the Stock, World Wide, for itself and its successors and assigns,

Borzone and Perna from any and all claims, demands, actions, suits, liabilities
and causes of action of any kind and nature whatsoever, fixed or contingent, and
waives all rights, which Saturn may have against either of them by reason of
their having served on the Saturn Board of Directors.

     (b) Saturn currently has in place Directors & Officers Liability insurance

place until December 31, 2001.

<PAGE>   4

     6. STOCKHOLDERS AGREEMENT: RESIGNATION. World Wide acknowledges and agrees
that, upon transfer of the Stock to Saturn, World Wide shall cease to be a party
to the Stockholders Agreement among the shareholders of Saturn dated March 21,
1995, as amended, and World Wide shall not have any rights or obligations
thereunder, including, but not limited to, the right to designate a director of
Saturn. World Wide shall deliver to Saturn at Closing the resignation of Mario
Borzone resigning as a director of Saturn, which resignation shall be effective
upon execution.

     7. ADDITIONAL COVENANTS. Saturn and World Wide, on behalf of themselves and
their respective subsidiaries, covenant and agree as follows:

     (a) Saturn agrees to terminate the license agreement it currently holds
from Bitron, a subsidiary of World Wide, as it applies to certain products at no
cost to Bitron. Upon execution of this Agreement, Saturn and Bitron shall
execute and deliver the Amendment No. 2 to Technical Information and License
Agreement (the "License Agreement") in the form attached as Attachment 7 to this
Agreement, which Amendment shall become effective upon Closing of this
Agreement. Saturn does not have any of the products being terminated from the
License Agreement in production. Promptly after execution of Amendment No. 2,
Saturn shall cease using Bitron Technology (as defined in the License Agreement)
related to such products and shall return to Bitron all documentation related to
such products in accordance with Section 3.06(b) and Article V of the License
Agreement (all of the obligations of which shall continue, notwithstanding the
termination of Article III pursuant to Amendment No. 2 to the License
Agreement). If an opportunity arises with respect to the products for which the
license will be terminated, Saturn and World Wide may elect to discuss the
opportunity and may mutually agree upon the terms of World Wide/Bitron, Inc.
granting to Saturn a license for any of these products on a case-by-case basis.

     (b) For a period of three (3) years from the date of this Agreement, Saturn
and World Wide agree not to employ or solicit to employ any person who is
employed by the other party in an executive, management or professional level
position or any person who is otherwise considered a key employee, without the
other party's prior written consent.

     (c) For a period of three (3) years from the date of this Agreement, World
Wide and Saturn agree not to operate a production facility within a twenty-five
(25) mile radius of any existing production facility of the other party. The
parties acknowledge that operation by World Wide or its affiliates of commercial
offices (that is non-production facilities) in the greater Detroit, Michigan
area would not constitute a breach of this provision.

     (d) For a period of three (3) years from the date of this Agreement, World
Wide and Bitron agree not to misuse any confidential or proprietary written
information regarding Saturn obtained from Saturn in connection with Saturn
Board of Director meetings to unfairly compete with Saturn. This restriction
shall not apply to information which (i) is now or subsequently becomes publicly
known or available through no fault of World Wide or Bitron S.p.A; or (ii) is
rightfully furnished to World Wide or Bitron S.p.A. by a third person who is not
prohibited from disclosing the information acquired by it in any manner.
Promptly after execution of this Agreement, World Wide shall return to Saturn
all documentation and information regarding Saturn in the possession of World
Wide or any of its subsidairies received in connection with

                                       4

<PAGE>   5

Saturn Board of Director and Shareholder meetings, and World Wide shall not
retain any copies thereof.

     (e) Except as permitted pursuant to the License Agreement, Saturn and World
Wide agree that they will not, without the other party's prior written consent,
use for any purpose or disclose to any person or entity any confidential or
proprietary information or trade secrets acquired by it in any manner
(including, but not limited to, information acquired in connection with Saturn
Board of Director and Shareholder meetings) which pertains to the business or
manner of operation of the other party's business (any such information,
"Confidential Information"). This restriction shall not apply to Confidential
Information that (i) is now or subsequently becomes publicly known or available
without breach of this provision by the recipient, (ii) or is, in the written
opinion of legal counsel, required to be disclosed by law or court order. If
either party (the "Requested Party") is requested or required (by oral
questions, interrogatories, requests for information or documents, subpoena,
civil investigative demand or similar process) to disclose any Confidential
Information of the other party, such Requested Party will provide the other
party with prompt notice of such request(s), to the extent practicable, so that
the party whose Confidential Information would be disclosed may seek an
appropriate protective order and/or waive compliance with the provisions of this
section. If, failing the entry of a protective order or the receipt of a waiver
hereunder, the Requested Party is, in the opinion of its counsel, compelled to
disclose Confidential Information or notes under pain of liability for contempt
or other censure or penalty, the Requested Party may disclose such Confidential
Information of the other party (to the extent necessary to avoid such liability,
censure, or penalty) without liability hereunder. Each party understands and
agrees that money damages may not be a sufficient remedy for any breach of its
obligations under this section and that the other party shall be entitled to
equitable relief, including injunction and specific performance, as a remedy for
any such breach. Such remedies shall not be deemed to be the exclusive remedies
for a breach of this section but may be in addition to all other remedies
available at law or equity to the parties.
