PURCHASE PRICE. The Purchased Assets shall be purchased by Buyer from Seller for a purchase price consisting of: (a) $1,737,000, payable as follows: (i) a fixed amount of $875,000 to Seller on the Closing Date by wire transfer, and (ii) an amount equal to $862,000, subject to adjustment as set forth in Section 4 hereof, to Seller on the last to occur of (a) expiration of 30 days after the Closing Date, or (b) resolution of any dispute as to the amount of any adjustment required pursuant to Section 4 below, by wire transfer; (b) the assumption of only those current liabilities of Seller set forth on SCHEDULE 3(b) hereto (the "Assumed Liabilities"); and (c) Warrants to purchase 50,000 shares of Buyer's Common Stock, pursuant to the Warrant Agreement (collectively, the "Purchase Price").

With respect to the allocation of the purchase price to the noncompetition covenant of Duescher as set forth in the Non-Competition Agreement, in the event such allocation causes Duescher to incur an amount of combined federal and state income taxes higher than he would incur if there were no such allocation of the Purchase Price to the Non-Competition Agreement, Buyer shall reimburse Duescher such premium over Duescher's resulting tax liability as if there had been no such allocation. In addition, in the event Buyer allocates a portion of the Purchase Price to any purchased depreciable equipment which results in the recapture of such depreciation, Seller shall reimburse Duescher such amount as is necessary to make Duescher "tax neutral," i.e., Seller shall reimburse Duescher the incremental increase in combined federal and state tax liabilities due to such recapture (at ordinary income tax rates) over the combined federal and state income tax liabilities Duescher would incur if an allocation causing such recapture were not made (at capital gains tax rates). 4 4. ADJUSTMENT TO PURCHASE PRICE. (a) ADJUSTMENT BASED ON ADJUSTED BOOK VALUE OF PURCHASED ASSETS. The Second Payment shall be adjusted based upon the Adjusted Book Value of the Purchased Assets listed on the Asset List as of the Closing Date, as follows: (i) if the Adjusted Book Value of the Purchased Assets as of the Closing Date is less than $243,000, then the Second Payment shall be decreased by the amount by which the Adjusted Book Value is less than $243,000, and (ii) if the Adjusted Book Value of the Purchased Assets as of such date is greater than $243,000, the Second Payment shall be increased by the amount by which the Adjusted Book Value of the Purchased Assets as of the Closing Date exceeds $243,000. (b) PROCEDURES FOR ADJUSTMENTS TO THE SECOND PAYMENT. The Purchase Price shall be adjusted as follows (the "Adjusted Purchase Price"): Attached hereto as SCHEDULE 4(b) is the Asset List. Not later than five (5) days following the Closing Date, Seller shall deliver to Buyer (i) the Closing Asset List, and (ii) the Closing Deduction List. The parties hereto hereby covenant and agree that no adjustment shall be made to the Purchase Price in respect of the Closing Asset List unless (i) the value of the assets as set forth on the Asset List is greater than the value of the assets set forth on the Closing Asset List by an amount of $5,000 or more, or (ii) the value of the assets as set forth on the Asset List is less than the value of the assets set forth on the Closing Asset List by an amount of $5,000 or more, in which case the Purchase Price shall be reduced or increased, as the case may be, on a dollar-for-dollar basis in an amount equal to the entire difference. Each of the Asset List, the Closing Asset List and the Closing Deduction List shall be prepared by Seller from Seller's books and records, consistent with Seller's past accounting practices consistently applied, and, so prepared, shall be presumptively valid unless Buyer shall give written notice to Seller of any disagreement or disagreements with the Closing Asset List or the Closing Deduction List within ten (10) days following its receipt of the Closing Asset List and Closing Deduction List, specifying in reasonable detail the nature and extent of such disagreement. (c) MANNER OF AJUSTMENTS. The Second Payment shall be reduced to reflect customer deposits made to Seller for orders which have not been delivered by the Seller prior to the Closing. In addition, it is acknowledged and agreed that (1) with respect to production and office equipment, the value of such assets in the Closing Asset List shall be determined by adding to the value of such assets on the Asset List the cost of any acquisitions between June 30, 1996 and the Closing Date and subtracting from the value of the Assets on the Asset List depreciation at a monthly rate of $1,800 and $114 for production and office equipment, respectively, and (2) with respect to inventory, the value of such asset on the Closing Asset List shall be determined by adding acquisitions to inventory and subtracting cost of sales from the value of the inventory on the Asset List, and (3) with respect to accounts receivable and prepaid expenses, the value on the Closing Asset List shall be the value of such assets on the Closing Date. 5 (d) DISAGREEMENT OVER ADJUSTED PURCHASE PRICE. If Seller and Buyer are unable to resolve any disagreement with respect to the Closing Asset List which would result in an adjustment to the Purchase Price or with respect to the Closing Deduction List within five (5) days following receipt by Seller of the notice referred to in Section 4(b) above, the disagreement shall be submitted for resolution to Coopers & Lybrand LLP (the "Evaluator"); provided, however, that all undisputed amounts will be paid within two (2) business days after that portion of the adjustment to the Second Payment is determined hereunder. The Evaluator shall act as an arbitrator to determine and resolve such disputes, based solely on presentations by Buyer and Seller and not by independent review. The Evaluator's resolution shall be made within fifteen (15) business days of the submission of the dispute, shall be in accordance with this Agreement, shall be set forth in a written statement delivered to Seller and Buyer and shall be final, binding and conclusive. Seller and Buyer shall each pay one half of all fees, costs and expenses of the Evaluator incurred in connection with the resolution of any dispute. 5. THE CLOSING. The Closing shall take place on the Closing Date and may be effected by means of facsimile transmissions (with same day delivery of executed counterparts among all parties) and wire transfer of the Purchase Price and shall, unless otherwise agreed to by the parties hereto, take place on September 9, 1996. If all conditions to the Closing have not been satisfied or waived on or prior to September 9, 1996, the Closing shall take place on that date which is five business days following the date on which all conditions to the Closing have been satisfied or waived. In the event the Closing does not occur on or prior to October 15, 1996 (the "Drop Dead Date"), the parties' rights and duties with respect to the transaction contemplated in this Agreement and the other Agreements shall cease. 6. NO ASSUMPTION OF LIABILITIES. (a) LIABILITIES NOT ASSUMED. Buyer shall not and does not assume any liabilities, obligations or commitments of Seller of any kind, known or unknown, contingent or otherwise, of whatsoever kind or nature, other than those Assumed Liabilities specifically identified on SCHEDULE 3(b) hereto, which Schedule shall include only (a) the obligation of Seller under the License Agreement to pay royalties to 3M (as to which Seller is responsible for all obligations incurred by Seller prior to Closing); (b) the obligation to pay 3M the balloon payment in the amount of Eleven Thousand Seven Hundred Seventy-Nine Dollars and Seventy-Nine cents ($11,779.79) on January 25, 1998; (c) the assumption of up to $1,000 for accrued sick leave and vacation payable to employees of Seller who Buyer may employ following the Closing; and (d) any open purchase and/or sales orders of Seller as set forth on SCHEDULE 3(b).

Notwithstanding anything contained in Section 12(b) above to the contrary, a Buyer Indemnified Party shall not be entitled to assert any claim for indemnification contained in Section 12(b) unless and until such time as the claims of all Buyer Indemnified Parties, in the aggregate, pursuant to Section 12(b) exceed $25,000 (exclusive of all tax savings and insurance proceeds received) and at which time all claims of any one or more Buyer Indemnified Party for indemnification pursuant to Section 12(b) above may be asserted in full. The remedies of Buyer set forth in this Section 12 are the exclusive remedies of Buyer and the Buyer Indemnified Parties under this Agreement, at law or in equity in the event of any breach of, or any inaccuracy in any of the representations, warranties, covenants or agreements made by Seller in this Agreement, any Exhibit or Schedule to this Agreement or any certificate, instrument or writing delivered in connection therewith; except, however, that in the event of an intentional breach, fraud, or reckless misrepresentation, Buyer's remedies against Seller shall not be limited by this provision and Buyer shall have all remedies against Seller available under applicable law. It is expressly understood that any adjustment to the Second Payment pursuant to the provisions of Section 4(b) shall not constitute a claim of a Buyer Indemnified Party for purposes of this provision. (c) INDEMNIFICATION BY BUYER. Buyer hereby covenants and agrees with Seller that, regardless of any investigation made at any time by or on behalf of Seller or any information Seller may have and regardless of the consummation of the transactions hereunder, Buyer shall indemnify Seller and Duescher and Seller's directors, officers, shareholders and affiliates (individually, a "Seller Indemnified Party"), and hold them harmless from, against and in respect of any and all costs, losses, claims, liabilities, fines, penalties, damages and expenses (including interest which may be imposed in connection therewith and court costs and reasonable fees and disbursements of counsel) incurred by any of them in connection with: (i) all liabilities of or claims against Seller Indemnified Parties of any nature, whether accrued, absolute, contingent or otherwise attributable to any event occurring after the Closing Date (whether known or unknown to Seller, or Buyer), relating to the operation by Buyer of the Purchased Assets from and after the Closing Date, except if (x) such liability results from or arises in connection with the breach of any of the representations, warranties, covenants or agreements made by Seller and/or Duescher in this Agreement, any other agreement referred to herein, any Schedule or Exhibit hereto or any certificate or instrument delivered in connection herewith or therewith, or (y) such liability is included under Section 12(b) above; 19 (ii) any breach of, or any inaccuracy in any of the representations, warranties, covenants or agreements made by Buyer in this Agreement, any other agreement referred to herein, any Exhibit or Schedule hereto or any certificate or instrument delivered in connection herewith or therewith; (iii) any attempt (whether or not successful) by any person to cause or require a Seller Indemnified Party to pay or discharge any debt, obligations, liability or commitment included in the Assumed Liabilities; or (iv) any action, suit, proceeding, compromise, settlement, assessment or judgment arising out of or incidental to any of the matters indemnified against in this Paragraph; provided, HOWEVER, that Buyer shall not be obligated to indemnify a Seller Indemnified Party under this Paragraph with respect to any settlement of a claim to which Buyer has not consented, which consent shall not unreasonably be withheld. (d) RIGHT TO DEFEND, ETC. If the facts giving rise to any claim for indemnification hereunder shall involve any actual claim or demand by any third person against a Buyer Indemnified Party or a Seller Indemnified Party (who are referred to hereinafter as an "Indemnified Party"), the indemnifying party shall be entitled to notice of and entitled (without prejudice to the right of any Indemnified Party to participate at its own expense with counsel of its own choosing) to defend or prosecute such claim at its own expense and through counsel of its own choosing if it gives written notice of its intention to do so no later than the time by which the interests of the Indemnified Party would be materially prejudiced as a result of its failure to have received such notice; provided, however, that if the defendants in any action shall include both the indemnifying party and the Indemnified Party and the Indemnified Party shall have reasonably concluded that counsel selected by the indemnifying party has a conflict of interest because of the availability of different or additional defenses to the Indemnified Party, the Indemnified Party shall have the right to select separate counsel to participate in the defense of such action on its behalf, at the expense of the indemnifying party. The Indemnified Party shall cooperate fully in the defense of such claim and shall make available to the indemnifying party pertinent information under its control relating thereto, but shall be entitled to be reimbursed, as provided in this Section 12, for all costs and expenses incurred by it in connection therewith. 13. POST-CLOSING COVENANTS. (a) CONSULTING SERVICES.

Each party shall provide the other party or parties with access to all relevant documents and other information pertaining to the Purchased Assets and Seller's business which are needed by such other party or parties for the purposes of preparing tax returns or responding to an audit by any governmental agency, to permit Buyer's auditors (at the expense of Buyer) to prepare audited financial statements of Seller and the Seller's business for the three year period ended June 30, 1996, or for any other reasonable purpose. Such access will be during normal business hours and not subject to time limitations. (c) CONFIDENTIALITY OBLIGATIONS.

Seller and Duescher acknowledge that, in the event of a violation of the terms and provisions of this SECTION 13(c), the remedies at law would not be adequate; and accordingly, in such event Buyer may proceed to protect and enforce its rights under this SECTION 13(c) by a suit in equity for specific performance hereof, or for an injunction against the violation hereof. 21 (d) APPLICATIONS AND ASSIGNMENTS. At the request of Buyer, Duescher shall assist Buyer and shall cause employees of Seller to assist and cooperate with Buyer in applying for and obtaining both domestic and foreign patents, or copyrights, as the case may be, on all Intellectual Property devised, discovered, developed, invented or authored by Duescher or any other employee of Seller prior to the Closing (or in which Duescher or such employees of Seller may otherwise obtain, or have otherwise obtained, any rights, while in the employ of the Seller) which relates to or was developed in connection with the Keltool Process or the business of Seller, that the Buyer deems to be patentable or copyrightable, and Duescher shall execute and shall cause all employees of Seller to execute at any time or times any and all documents and perform all acts reasonably requested by Buyer which Buyer deems to be necessary or desirable in order to obtain such patents or copyrights or otherwise to vest in Buyer full and exclusive title and interest in and to all such Intellectual Property, to protect the same against infringement by others and otherwise to aid the Buyer in connection with any continuations, renewals or reissues of any patents or copyrights, or in the conduct of any proceedings or litigation in regard thereto. Buyer shall pay Duescher and the employees of Seller for their services in connection with the applications made pursuant to this Paragraph on an hourly basis, which hourly rate shall be agreed upon by the parties at that time and shall in all events be reasonable under the circumstances. All filing fees and documentation expenses incurred in procuring any patent or copyright shall be born by the Buyer. (e) REFERRAL.
