                           Assumed Contracts attached hereto (the "Assumed

and duly executed by Seller, against delivery by Purchaser to Seller of the
payment provided for in Section 1.6 hereof. At the Closing, Purchaser shall

hereto as Exhibit B and such other instruments of assumption as may be
reasonably necessary to evidence Purchaser's assumption of the Assumed
Liabilities, all in the form and substance reasonably satisfactory to Seller and
duly executed by Purchaser.

Division as presently conducted. Seller is qualified to do business as a foreign
corporation in Ohio and each other jurisdiction in which the conduct of the
business of the PMC Division or the ownership of the Purchased Assets makes such
qualification necessary.

                  3.2. AUTHORIZATION OF SELLER. Seller has full power, authority
and legal right and capacity to enter into this Agreement, to perform its
obligations hereunder, and to consummate the transactions contemplated hereby.
The execution, delivery and performance by Seller of this Agreement have been
duly authorized by all necessary corporate action. This Agreement has been duly
executed and delivered by Seller and constitutes a valid and binding obligation
of Seller, enforceable against Seller in accordance with its terms.

                  3.3. NO CONFLICT OR VIOLATION. Neither the execution and
delivery of this Agreement by Seller, nor the consummation of the transactions
contemplated hereby, will result in (i) a violation of, or a conflict with,
Seller's Articles of Incorporation or Bylaws, (ii) a breach of, or a default (or
an event which, with notice or lapse of time or both would constitute a default)
under or result in the termination of, or accelerate the performance required
by, or create a right of termination or acceleration under, any contract or
Permit to which Seller is a party or by which the Purchased Assets or the PMC
Division is bound or affected, (iii) a violation by Seller of any applicable
law, statute, code, ordinance, rule, regulation or order whether federal, state,
local or other ("Laws"), or a violation by Seller of any order, judgment, writ,
injunction, decree or award to which Seller is a party or by which the Purchased
Assets or the PMC Division are bound, or (iv) an imposition of any Encumbrance
on the Purchased Assets.

                  3.4. CONSENTS AND APPROVALS. No consent, Permit, approval or
authorization of, or declaration, filing, application, transfer or registration
with, any governmental or regulatory authority, or any other person or entity is
required to be made or obtained by Seller by virtue of its execution, delivery
and performance of this Agreement or to avoid the loss of any Permit, or the
violation, breach or termination of, or the creation of Encumbrances on any
Purchased Assets pursuant to the terms of, any Law, or to enable Purchaser to
own the Purchased Assets and continue the operation of the PMC Division on and
after the Closing Date in substantially the same manner as it is presently
conducted by Seller.

                  3.5. NO ACTIONS OR PROCEEDINGS RELATED TO THE AGREEMENTS.
There are no pending or, to Seller's knowledge, threatened actions, claims,
lawsuits, proceedings, arbitrations, mediations or other disputes ("Actions"),

it is reasonable to expect will or could, individually or in the aggregate,

<PAGE>   12

Purchased Assets. None of the Purchased Assets is subject to any commitment or
other arrangement for their use by any affiliated party of Seller or any third
party. EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, SELLER EXCLUDES AND
DISCLAIMS ANY AND ALL EXPRESS AND IMPLIED WARRANTIES, INCLUDING, WITHOUT
LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. SELLER MAKES NO WARRANTIES OTHER THAN THOSE EXPRESSLY SET
FORTH IN THIS AGREEMENT.

                  3.13. LEASES. True and complete copies of all leases,
subleases, and other occupancy or lease agreements under which Seller leases,
subleases, occupies or uses any real or personal property included in the
Purchased Assets, including all amendments, modifications, renewals and
extensions thereof (the "Leases") have been previously furnished to Purchaser.
All of the Leases are legal, valid and binding obligations of the parties
thereto and are in full force and effect. There is no existing default,
violation or breach under any Lease nor any event or condition which after
notice or lapse of time or both would constitute such a default, violation or
breach.

                  3.14. ASSUMED CONTRACTS. True and complete copies of all
Assumed Contracts and all material contracts of the PMC Division with customers,

of the Assumed Contracts are enforceable, legal, valid and binding obligations
of the parties thereto and are in full force and effect.

each, has been previously furnished to Purchaser. The PMC Division has no
outstanding contracts with any customers or suppliers which require payments in
excess of $10,000 on an annualized basis. There are no outstanding disputes with
any major customer or supplier and no major customer or supplier has refused to
do business with the PMC Division or has stated its intention not to continue to
do business with or increase or reduce its purchases from or sales to the PMC
Division or Purchaser upon consummation of the transactions contemplated hereby.
Seller has no reason to believe that any customer account of the PMC Division is
not collectible in accordance with its terms except to the extent of any
reserves reflected in the Financial Statements. No existing contractual
arrangement with a customer of the PMC Division other than purchase orders which
will be filled within twelve months contains any fixed price arrangement.

governmental authority necessary for the lawful and

<PAGE>   13

efficient operation of the PMC Division as presently conducted or the ownership

and efficient operation of the PMC Division as presently conducted, including
all rights to the name "PMC" and other names utilizing "PMC" (the "PMC
Intellectual Property"), without any known conflict with the rights of others.
There are no outstanding licenses or agreements of any kind relating to Seller's
grant of any of its rights, title and interest in and to any PMC Intellectual
Property. Seller has not received any communication alleging that it has
violated or, by operating the business of the PMC Division, would violate, any
of the proprietary rights of any other person or entity.

                  3.19. EMPLOYEES AND RELATED MATTERS. Purchaser has been
provided with a list of the names, current annual salaries, bonuses, employee
benefits, accrued vacation times, sick pay and other compensation, date of hire
and location of all the present employees of Seller who provide services to the
PMC Division. The Schedule of Benefit Plans attached hereto includes a true and
complete list of all pension, bonus, profit sharing, stock option and employee
benefit plans maintained by Seller or to which Seller contributes or is required
to contribute ("Benefit Plans"). All Benefit Plans have been maintained and
administered in compliance with the provisions of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), and all other applicable Laws. There
are no employment or consulting contracts or arrangements, including pensions,
bonus or profit sharing plans, or other severance or termination contracts or
arrangements which may constitute contractual obligations of Seller relating to
the PMC Division which are not terminable on 30 days' notice or less. There are
no collective bargaining agreements with any union or other bargaining group for
any of Seller's employees employed in the PMC Division, nor is Seller aware of
any efforts by any such employees to organize or participate in any of the
foregoing. To the best knowledge of Seller, no employee of the PMC Division is
in violation of any of its obligations to, or any employment agreement with, a
prior employer. Seller has conducted the business of the PMC Division in
compliance with all Laws pertaining to the employment of employees, including,
without limitation, all Laws relating to labor relations, equal employment
practices, fair employment practices, entitlements, COBRA, prohibited
discrimination, ERISA, terms and conditions of employment, wages and hours, and
other similar employment practices and acts, and Seller is not engaged in any
unfair labor practices and is not a party to any Action involving a violation or
alleged violation of any of the foregoing Laws. There are no pending or, to
Seller's knowledge, threatened Actions against Seller by any employee with
respect to any matter arising out of, relating to or in connection with such
employee's employment by Seller.

                  3.20. ANTICIPATED RECEIPTS BY SELLER. Seller is a party to an
agreement with a customer pursuant to which such customer has agreed to pay to
Seller at least $1,500,000 prior to the date hereof. Although such payment has
not been received to date, Seller is not aware

                                       8
<PAGE>   14

of any reason that such payment will not be made and believes in good faith that
it will receive such payment prior to October 31, 1996.

                  3.21. FULL DISCLOSURE. No representation, warranty or other
statement of Seller contained in this Agreement or any other document,
certificate or written statement furnished to Purchaser in connection with the
transactions contemplated hereby contains any untrue statement of a material
fact or omits to state a material fact necessary in order to make the statements
contained herein or therein not misleading.

Indemnified Parties"), and shall reimburse each Seller Indemnified Party, on
demand, for any Damages resulting from, arising from or relating to the
following: (i) the Assumed Liabilities; (ii) the operation of the PMC Division
after the Closing Date; (iii) any breach or default in the performance by
Purchaser of any covenant or agreement of Purchaser contained herein, or in any
Schedule or Exhibit hereto, or in any other instrument delivered or to be
delivered by or on behalf of Purchaser pursuant hereto; (iv) any breach of
warranty or inaccurate or erroneous representation made by Purchaser herein, or
in any Schedule or Exhibit hereto, or in any other instrument delivered or to be
delivered by or on behalf of Purchaser pursuant hereto; and (v) any liability
arising out of any and all Actions, demands, judgments, costs and expenses
incident to any of the foregoing.

                  8.3. CLAIMS FOR INDEMNITY. Whenever a claim for Damages shall
arise for which one party (the "Indemnified Party") shall be entitled to
indemnification hereunder, the Indemnified Party shall notify the other party
hereto (the "Indemnifying Party") in writing within 30 days of the first receipt
of notice of such claim, and in any event within such shorter period as may be
necessary for the Indemnifying Party to take appropriate action to resist such
claim. Such notice shall specify all facts known to the Indemnified Party giving
rise to such indemnity rights and shall estimate the amount of the liability
arising therefrom. The right of the Indemnified Party to indemnification and the
estimated amount thereof, as set forth in this notice, shall be deemed agreed to
by the Indemnifying Party unless, within 30 days after the mailing of such
notice, the Indemnifying Party shall notify the Indemnified Party in writing
that it disputes the right of the Indemnified Party to indemnification. If the
Indemnified Party shall be duly notified of such dispute, the parties shall
attempt to settle and compromise the same, or if unable to do so within 20 days
of the Indemnifying Party's delivery of notice of a dispute, such dispute shall
be settled by binding arbitration before a single arbitrator in the County of
Hamilton, State of Ohio, in proceedings conducted by the American Arbitration
Association and pursuant to such organization's rules for commercial disputes,
and any rights of indemnification established by reason of such settlement,
compromise or arbitration shall promptly thereafter be paid and satisfied by the
Indemnifying Party.

                  8.4. INSURANCE PROCEEDS. Neither party shall be entitled to
indemnification for any claim for Damages for which it would otherwise be
entitled to indemnification hereunder to the extent that such party has received
insurance proceeds covering such Damages.

                  8.5. DEFENSE OF CLAIMED BREACHES. For purposes of this
Section, any assertion of fact and/or law by a third party which, if true, would
constitute a breach of a representation or warranty made by a party to this
Agreement shall, on the date that assertion is made, immediately invoke that
party's obligation to protect, defend, hold harmless and indemnify the other
party to this Agreement.

                  8.6. LIMITATIONS ON INDEMNIFICATION. No amount may be
recovered by any Indemnified Party under this Section 8 unless and until the
aggregate amount of the Damages suffered by such Indemnified Party exceeds
$10,000, whereupon such Indemnified Party shall be entitled to recover all
Damages in excess of such amount; provided that the maximum

                                       14
<PAGE>   20

aggregate amount of Damages for which any Indemnified Party shall be entitled to
indemnification shall in no event exceed $1,000,000. Seller's liability for
indemnification under clauses (iii) and (iv) of Section 8.1 shall expire on the
first day of the first month which begins twenty-four (24) months after the
Closing Date as to all claims not asserted by written notice specifying the
basis for such claim and referring to this Agreement by such date, except for
obligations arising or under Section 3.2 hereof, the second sentence of Section
3.11 hereof and Section 9 hereof.

                  8.7. INDEMNIFICATION EXCLUSIVE. Following the Closing, the
indemnification provisions of this Section 8 shall be the exclusive remedy for
any breach of any representation, warranty, covenant or agreement made in this
Agreement.

         9. COVENANT NOT TO COMPETE

                  9.1. COVENANT NOT TO COMPETE. Seller shall not, for a period
of five years from the Closing Date, directly or indirectly, own, manage,
finance, operate, join, control or participate in the ownership, management,
financing, operation or control of, or connected in any manner with, any
business that competes with the PMC Division in the areas of business in which
the PMC Division operates as of the Closing Date; provided, however, that this
Section 9.1 shall not preclude Seller from developing, for use in its own
products and not for separate resale to others, computerized control systems
which do not incorporate any proprietary technology owned by Purchaser. For
purposes of this Agreement, the term "compete" shall mean (i) calling on,
soliciting or taking away, as a client or customer any individual or entity that
was a client or customer of the PMC Division, during the 24 calendar month
period immediately preceding any such act for the purpose of competing with
Purchaser; (ii) hiring, soliciting, taking away or attempting to hire, solicit
or take away any employee of Purchaser either on behalf of itself or any other
person or entity; or (iii) entering into or attempting to enter into any
business substantially similar to or competing in any way with the business of
the PMC Division, either alone or with any individual or entity in the areas of
business in which the PMC Division operates as of the Closing Date.

                  9.2. REASONABLENESS OF RESTRICTIONS. Seller agrees that the
restrictions set forth in Section 9.1, above are reasonable and not burdensome
and that they are properly required to protect the goodwill of the business of
the PMC Division for Purchaser. In the event that such restrictions are deemed
to be unreasonable by a court of competent jurisdiction in any respect, then
Seller and Purchaser agree that they will submit to the reduction of such
restrictions to such extent as the court shall deem reasonable.

                  9.3. INJUNCTIVE RELIEF. Seller acknowledges that a breach by
it of the provisions of this Section 9 cannot be reasonably or adequately
compensated in damages in an action at law and that such breach will cause
Purchaser irreparable injury and damage. By reason thereof, Seller agrees that
Purchaser shall be entitled, in addition to any other remedies it may have under
this Agreement or otherwise, to temporary, preliminary and/or permanent
injunctive and other equitable relief to prevent or curtail any breach of this
Agreement, without

                                       15
<PAGE>   21

proof of actual damages that have been or may be caused to Purchaser by such
breach or threatened breach.

         10. MISCELLANEOUS PROVISIONS

                  10.1. BUSINESS TERMS GOING FORWARD. Sieb & Meyer shall process
each purchase order from Seller received by Sieb & Meyer after the Closing Date
and prior to the date Seller has paid in full the Remaining Account Receivable
in a similar manner as Sieb & Meyer has processed purchase orders of Seller
during the previous two months; provided, however, that prior to the date Seller
has paid in full the Remaining Account Receivable, Sieb & Meyer shall be under
no obligation to sell or ship any products to Seller in connection with any
purchase order unless Seller provides Sieb & Meyer with written confirmation of
the Federal Wire Transfer Number for a wire in an amount which is sufficient to
cover payment of the products requested in such purchase order.

                  10.2. PURCHASER TO ACT AS AGENT FOR SELLER. Nothing in this
Agreement is intended to constitute an agreement to assign any asset, right or
claim if such assignment, without the consent of another party, would be
ineffective or would constitute a breach of an agreement relating thereto or
otherwise adversely affect the value of such asset, right or claim such that
Purchaser would not receive all of the value thereof. To the extent any such
third party consent is required with respect to any asset, right or claim, then
Seller shall provide to Purchaser the benefits thereunder, including without
limitation, enforcement thereof for the benefit of Purchaser.

                  10.3. TERMINATION PRIOR TO CLOSING. This Agreement and the
transactions contemplated hereby may be terminated at any time prior to the
Closing Date (i) by the mutual written consent of Purchaser and Seller, (ii) by
either Purchaser or Seller in writing, without liability to the party
terminating this Agreement on account of such termination, if the Closing shall
not have occurred on or before October 15, 1996, or (iii) by either Purchaser or
Seller in writing, without liability to the party terminating this Agreement on
account of such termination, if the non-terminating party (A) fails to perform
in any material respect any agreement contained herein required to be performed
prior to the Closing Date, or (B) materially breaches any of its
representations, warranties or covenants contained herein; provided, however,
that termination pursuant to this Section 10.3 shall not relieve the defaulting
or breaching party from any liability to the non-defaulting party.

                  10.4. FURTHER ASSURANCES. Each party hereto shall, at any time
on or after the Closing Date, execute, acknowledge and deliver any further
assignments and other assurances, documents and instruments of transfer,
reasonably requested by the other party, and will take any other action that may
be requested by the other party, for the purpose of assigning, transferring,
granting, conveying and confirming to Purchaser, or reducing to possession, any
or all property to be conveyed and transferred by this Agreement. Without
limiting the generality of the foregoing, from and after the Closing Date,
Seller shall promptly, and in any event within three business days, transfer or
convey to Purchaser any cash or other property which may come into Seller's
possession relating to the Purchased Assets or the PMC Division.

<PAGE>   22

                  10.5. BULK SALES LAW. Without admitting that the bulk sales
law of any state is applicable to the transactions contemplated by this
Agreement, the parties waive compliance with the bulk sales laws of all states.

                  10.6. NO THIRD PARTY BENEFICIARIES. The representations,
warranties, covenants and agreements contained in this Agreement are for the
sole benefit of the parties hereto, and their respective successors and
permitted assigns, and no provision of this Agreement shall be construed as
conferring any rights on any third party or parties.

                  10.7. CONFIDENTIALITY; PRESS RELEASES AND ANNOUNCEMENTS. The
parties shall, and shall cause their respective employees, officers, directors
and other representatives to, hold in strict confidence any and all information
or data obtained in connection with this Agreement. Except as may otherwise
required by Law, neither party will issue or authorize to be issued any press
release or other announcement concerning this Agreement or any of the terms
hereof or the transactions contemplated hereby without the prior written
approval of the other party.

                  10.8. TAXES. Seller shall pay all sales and use taxes and
transfer fees, if any, arising out of the transfer of the Purchased Assets and
shall pay its portion, prorated as of the Closing Date, of state and local
property taxes. Purchaser shall not be responsible for any payroll, excise,
income, business, occupation, withholding or similar tax, or any taxes of any
kind, related to any period up to and including the Closing Date.

                  10.9. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. Regardless
of any investigation at any time made by or on behalf of any party, or of any
information any party may have in respect thereof, all representations and
warranties made hereunder or pursuant hereto or in connection with the
transactions contemplated hereby shall survive the Closing.

                  10.10. EXPENSES. Each of the parties shall pay all costs and
expenses incurred by it or on its behalf in connection with this Agreement and
the transactions contemplated hereby, including, without limiting the generality
of the foregoing, fees and expenses of its own financial consultants,
accountants and counsel.

                  10.11. ENTIRE AGREEMENT. All agreements, covenants,
representations and warranties, express or implied, oral and written, of the
parties with regard to the subject matter of this Agreement are contained in
this Agreement, the Schedules and Exhibits hereto, the documents referred to
herein or the documents or instruments implementing the provisions hereof. This
is an integrated agreement.

                  10.12. GOVERNING LAW AND CHOICE OF FORUM. The validity,
construction and performance of this Agreement, and any Action arising out of or
relating to this Agreement, shall be governed by the Laws of the State of Ohio,
without regard to the Laws as to choice or conflict of Laws.

                  10.13. INTERPRETATION. The language in all parts of this
Agreement shall be in all cases construed simply according to its fair meaning
and not strictly for or against any party.

                                       17
<PAGE>   23

The captions of the Sections and Subsections of this Agreement are for
convenience only and shall not affect the construction or interpretation of any
of the provisions of this Agreement.

                  10.14. WAIVER AND AMENDMENT. This Agreement may be amended,
supplemented or modified only through an express written instrument signed by
both parties or their respective successors and permitted assigns. Any party may
specifically and expressly waive in writing any portion of this Agreement or any
breach hereof, but only to the extent such provision is for the benefit of the
waiving party, and no such waiver shall constitute a further or continuing
waiver of any preceding or succeeding breach of the same or any other provision.
The consent by one party to any act for which such consent was required shall
not be deemed to imply consent or waiver of the necessity of obtaining such
consent for the same or similar acts in the future, and no forbearance by a
party to seek a remedy for noncompliance or breach by the other party shall be
construed as a waiver of any right or remedy with respect to such noncompliance
or breach.

                  10.15. ASSIGNMENT. Neither this Agreement nor any interest
herein or right hereunder shall be assignable (voluntarily, involuntarily, by
judicial process, operation of Law or otherwise), in whole or in part, by any
party without the prior written consent of all other parties. Any attempt at
such an assignment without such consent shall be void. Notwithstanding the other
provisions of this Section 10.15, if Seller, in connection with any sale of all
or substantially all of its assets or any merger or consolidation in which
Seller does not survive, obtains a written agreement from the purchaser of such
assets or the surviving entity in such merger or consolidation expressly
assuming and agreeing to perform, for the benefit of Purchaser, all of Seller's
obligations hereunder, then Purchaser's consent shall not be required. Each of
the terms, provisions and obligations of this Agreement shall be binding upon,
shall inure to the benefit of, and shall be enforceable by the parties and their
respective legal representatives, successors and permitted assigns.

                  10.16. NOTICES. All notices, requests, demands and other
communications made under this Agreement shall be in writing, correctly
addressed to the recipient at the addresses set forth below and shall be deemed
to have been duly given (i) upon delivery, if served personally on the party to
whom notice is to be given, (ii) upon transmittal, if telecopied and receipt is

intended to be severable. Should any provision of this Agreement or the
application thereof be judicially declared to be or become illegal, invalid,
unenforceable or void, the remainder of this Agreement shall continue in full

         FOR GOOD AND VALUABLE CONSIDERATION, the receipt and sufficiency of
