                        CONVERSION OF SHARES IN THE MERGER

    The manner of carrying into effect the Merger, and the manner and basis of
converting the shares of PVS into shares of the Surviving Corporation are as
follows:

    3.1  VAUGHN'S COMMON STOCK. No shares of common stock of Vaughn issued as
of the Effective Date shall be converted as a


                                       4


result of the Merger, but all of such shares shall remain issued shares of 
common stock of the Surviving Corporation.

    3.2 PVS'S COMMON STOCK.

         (a)  CONVERSION. On the Closing Date, each share of common stock of
PVS issued and outstanding shall be converted into the number of shares of
common stock of the Surviving Corporation as determined by the following
formula;

 1 PVS share = [($2,500,000 + $BV) DIVIDED BY 1000 DIVIDED BY $MP] Vaughn shares

            Total Vaughn shares issued = ($2,500,000 + $BY) DIVIDED BY $MP

    where 1000 is the number of outstanding shares of PVS at the Closing
    Date, "BY" represents the Book Value of PVS on the Closing Date and
    "MP" represents the market price of one share of Vaughn's common stock
    which for this purpose shall be the average of the closing NASDAQ
    price published in the Wall Street Journal for the seven trading days
    ending one week prior to the Closing Date.

Certificates representing fractional shares will not be issued.  Each issued
share of common stock of PVS held in the PVS's treasury at the Effective Date
shall be canceled and shall not be converted.  The preliminary Book Value of PVS
shall be determined at the Closing Date based on the books and records of PVS,
following review by Wolf & Company, LLP and such Book Value shall thereafter be
adjusted as necessary to conform to generally accepted accounting principles,
including any adjustments resulting from the special procedures (including
observation of inventory, review of receivables and liabilities and such other
procedures as may be requested by the Surviving Corporation) performed by
certified public accountants selected by the Surviving Corporation, all within
forty-five (45) days thereafter. Wolf & Company, LLP shall complete its review
of the Book Value of PVS within thirty (30) days after the Closing Date so that
the accountants selected by the Surviving Corporation will have an additional
fifteen (15) days to complete their procedures.

         (b) STOCK CERTIFICATES. Within forty-five (45) days after the Closing
Date, after determination of Book Value in accordance with Section 3.2(a), the
PVS Shareholders shall surrender their certificates representing such shares for
cancellation and, subject to the Stock Pledge Agreement, shall receive
certificates representing the Stock Consideration.

    3.3 EFFECT OF THE MERGER. At the Closing Date, the Surviving Corporation
shall succeed to, without other transfer, act or deed of any person, and shall
possess and enjoy all the rights, privileges, immunities, powers and franchises
both of a public and private nature, and be subject to all the restrictions,


                                       5


disabilities and duties of each of the Merging Corporations, and all property,
real, personal and mixed, including patents, trademarks, trade names, and all
debts due to any of the Merging Corporations shall be vested in the Surviving
Corporation; and all such property, rights, privileges, immunities, powers and
franchises, and all and every other interest shall be thereafter the property of
the Surviving Corporation, and the title of any real estate vested by deed or
otherwise in any of said Merging Corporations shall not revert or be in any way
impaired by reason of the Merger; provided, however, that all rights of
creditors and all liens upon any property of any of said Merging Corporations
shall be preserved unimpaired, and all debts, liabilities and duties of the
Merging Corporations, respectively, shall attach to the Surviving Corporation
and may be enforced against it to the same extent as if said debts, liabilities
and duties had been incurred or contracted by the Surviving Corporation.

                        REPRESENTATIONS AND WARRANTIES OF

    PVS and its Shareholders jointly and separately make the following
representations and warranties to Vaughn with the intention that Vaughn may rely
upon the same and acknowledge that the same shall be true on the Effective Date

corporate power and authority to own, lease and use its properties and assets
and is entitled to operate its business as and in the places where such
properties and assets are now owned, leased or operated as such business is now

              reasonable attorneys' fees, court costs, and costs of collection,
              resulting from any untrue representation, breach of warranty or
              non-fulfillment of any covenant or agreement by Vaughn contained
              in this Agreement;

    (ii)      any claims for finders fees or brokerage or other commission by
              any person, firm or corporation, including all reasonable
              attorneys fees, court costs and costs of collection, arising by
              reason of any services alleged to have been rendered to or at the
              instance of Vaughn with respect to this Agreement or any of the
              transactions contemplated by this Agreement; and

    (iii)     any and all actions, suits, proceedings, claims, demands,
              assessments, judgments, reasonable costs and expenses, including
              all reasonable attorneys' fees, court costs and costs of
              collection, incident to any of the foregoing or incurred in
              investigating or attempting to avoid the same or to oppose the
              imposition thereof consistent with the other terms of this
              Agreement.

    11.3 CLAIMS PROCEDURE. The following exclusive procedure shall govern any
and all indemnity claims which may be brought pursuant to the terms of this
Agreement.

         (a)  NOTICE OF CLAIM. The PVS Shareholders may seek indemnification
from Vaughn, or the Surviving Corporation, as successor to Vaughn. The Surviving
Corporation may seek indemnification from the PVS Shareholders. The party
seeking indemnification shall promptly give written notice to the Indemnifying
Party of all claims whether between the parties or raised by a third party, that
could constitute a claim for indemnification. The written notice shall specify
to the extent known by the party seeking indemnification:

    (i)  the factual basis for such claim and the alleged violation of this
         Agreement, and


                                       27


    (ii) the amount of the claim.

         (b)  INVESTIGATION: PAYMENT. Following receipt of notice from the
party seeking indemnification, the Indemnifying Party shall have 30 days to make
such investigation of the claim as the Indemnifying Party deems necessary or
desirable. For the purposes of such investigation, the party seeking
indemnification agrees to make available to the Indemnifying Party and/or its
authorized representatives the information relied upon by the party seeking
indemnification to substantiate the claim, as well as any other information
bearing thereon reasonably requested by the Indemnifying Party. If the party
seeking indemnification and the Indemnifying Party agree at or prior to the
expiration of the 30 day period (or any mutually agreed upon extension thereof)
to the validity and amount of such claim, the Indemnifying Party shall
immediately pay to the party seeking indemnification the full amount of the
claim.

         (c)  ARBITRATION.  If the party seeking indemnification and the
Indemnifying Party do not agree within 30 days from the date of a claim (or any
mutually agreed upon extension thereof) the dispute shall be settled by
arbitration in accordance with the commercial rules of the American Arbitration
Association, such arbitration to be venued in Chicago, Illinois. The decision of
the Arbitrator(s) shall be final and binding upon the parties. Any expenses of
such arbitration including, without limitation, the fees of the arbitrators,
shall be paid as determined appropriate by the arbitrators. Third party claims
shall be settled by such means as may be appropriate subject to the terms of
11.3(d), below.

         (d)  PARTICIPATION IN DEFENSE. With respect to any claim made by a 
third party as to which any party is entitled to indemnification, the 
Indemnifying Party shall have the right, at its own expense, to participate 
in or assume control of the defense of such claim, and the party seeking 
indemnification shall cooperate fully with the Indemnifying Party. If the 
Indemnifying Party elects to assume control of the defense of any such 
third-party claim, the party seeking indemnification shall have the right to 
participate in the defense of such claim at its own expense and, if it so 
elects, the Indemnifying Party shall have no right to settle or compromise 
such third-party claim. If the Indemnifying Party does not elect to assume 
control or otherwise participate in the defense of any such third-party 
claim, it shall be bound by the results obtained by the party seeking 
indemnification with respect to such claim.

         (e)  COLLATERAL.  If an indemnification amount owing by the PVS
Shareholders is determined by mutual agreement or by arbitration as provided in
this Section and not satisfied by the PVS Shareholders within 15 days after such
a determination, then such claim shall be satisfied by:

    (i)  offset against payments otherwise due the PVS Shareholders and, if
         such offset is not sufficient to satisfy the 


                                       28


         indemnification obligation; or

    (ii) pursuant to the terms of the Stock Pledge Agreement attached as
         Exhibit 6.2.

    11.4 LIMITATION OF INDEMNIFICATION OBLIGATION.  Notwithstanding any other
provisions in this Agreement, the liabilities of the parties under this
Agreement shall be limited as follows:

    (i)       Except as provided in Section 11.4(iv), a party's aggregate
              liability for any and all claims (including, without limitation,
              claims of any regulatory authority) shall be limited to the sum
              obtained by multiplying the value of the Stock Consideration as
              of the Closing Date by Ten Percent (10%).

    (ii)      Except as provided in Section 11.4(iv),a party's aggregate
              liability for any and all claims (limited as provided in Section
              11.4(i)) shall continue until issuance of the independent audit
              report on the Surviving Corporation for the Surviving
              Corporation's fiscal year ending January 31, 1997.

    (iii)     The provisions of Section 11.4(ii) notwithstanding, a party
              shall remain liable for all claims brought pursuant to this
              Section prior to the date specified in Section 11.4(ii) until
              resolution and satisfaction of such claim in accordance with this
              Section.

    (iv)      Between the date hereof and the Closing Date, the parties shall
              conduct such diligence as they consider necessary and
              appropriate. To the extent that the parties discover specific
              contingent liabilities of any party during the diligence process,
              the parties shall use their best efforts to quantify the
              potential exposure associated with such contingent liability and
              the potential liability of the obligated party for
              indemnification claims shall increase by a percentage of the
              value of the Stock Consideration equal to the agreed value of
              such contingent liability. At closing, such Stock Consideration
              shall be subject to the terms of the Stock Pledge Agreement
              pending resolution of such contingencies.  If the parties cannot
              agree upon the value of such contingent liability or if such
              value exceeds an additional Ten Percent (10%) of the Stock
              Consideration hereunder, either party may elect to cancel and
              terminate this Agreement and elect not to proceed with the
              Merger.


                                       29


    (v)       The parties intend that the Merger contemplated by this Agreement
              shall be treated as a "pooling of interests" in accordance with
              generally accepted accounting principles and rules and
              regulations promulgated by the SEC. To the extent that any
              provision of this Section is deemed, by the SEC or in the
              judgment of the Surviving Corporation, to make the "pooling of
              interests" method of accounting unavailable, such provision shall
              be deemed null and void and the indemnification provisions of
              this Section shall be deemed amended to the extent required to
              qualify for "pooling of interests" accounting treatment.

    11.5 SOLE REMEDY. The rights of the Surviving Corporation and the rights of
the PVS Shareholders as set forth and as limited in this Article Il, shall be
the sole and exclusive remedies of Vaughn, or the Surviving Corporation as its
successor, and of PVS and the PVS Shareholders hereunder.

                               POST-CLOSING AGREEMENTS

    12.1 FURTHER ASSURANCES. Subsequent to the Closing Date, to the extent that
any additional instruments, agreements or consents are reasonably necessary to
consummate the transactions contemplated by this Agreement, the parties agree to
cooperate fully and to execute such instruments, agreements or consents in a
timely fashion upon request by another party hereto.

                                      ARTICLE 13

                                     MISCELLANEOUS

accordance with the laws of the State of Minnesota, excluding any choice of law
rules that may direct the application of the laws of another jurisdiction.

    13.2 ENTIRE AGREEMENT.  This Agreement and the exhibits and agreements
attached hereto constitute the entire agreement of the parties with respect to
the subject matter hereof and may not be modified, amended, or terminated except
by a written agreement signed by all of the parties hereto. The Confidentiality
Agreement previously executed by the parties shall remain in full force and
effect notwithstanding the Closing of the transactions contemplated by this
Agreement, except as may be required by law or generally accepted accounting
principles.

    13.3 WAIVER AND AMENDMENT. Any party may waive any provision, breach or
default of this Agreement; provided, however, that no 


                                       30


waiver of any provision, breach or default hereunder shall be considered 
valid unless in writing and signed by the party giving such waiver, and no 
waiver shall be deemed a waiver of any other provision or any subsequent 
breach or default of the same or similar nature.
