Merger Agreement. Pursuant to the Merger Agreement, Lawrence Merger Subsidiary was merged with and into LSL, and all shares of LSL Common Stock were converted into the right to receive shares of ATMI Common Stock (the "Merger"). The receipt of ATMI Common Stock was dependent upon the approval of Advanced Technology stockholders of a certain merger and exchange with an unrelated third party. The Merger was consummated on October 10, 1997. The aggregate number of shares of ATMI Common Stock exchanged for the outstanding shares of LSL Common Stock (the "Lawrence Acquisition Consideration") was equal to $78 million divided by the "Lawrence Acquisition Average Closing Price" of Advanced Technology Common Stock. The purchase price was subject to adjustment as provided in the Merger Agreement, including a dollar-for-dollar adjustment based upon any change in the combined net worth of LSL and LSLMS as indicated on their unaudited financial statements as of December 31, 1996, and their audited financial statements as of the effective time of the Merger ("Lawrence Effective Time"). "Lawrence Acquisition Average Closing Price" means Page 5 of 10 Pages --- --- the average closing price of Advanced Technology Common Stock as reported by Nasdaq for the twenty trading days preceding (and including) the third day prior to the date of the Annual Meeting of the Advanced Technology stockholders; subject to a high of $21.00 per share and a low of $17.00 per share. The Lawrence Acquisition Average Closing Price used to determine the number of ATMI Common Stock to be exchanged for LSL Common Stock was $21.00 per share. The Lawrence Acquisition Consideration was distributed among the LSL stockholders in proportion to their respective holdings of LSL Common Stock immediately prior to the consummation of the Merger. The obligation of LSL to consummate the Merger was subject to, among other things, the appointment of Lamonte H. Lawrence promptly after the Lawrence Effective Time to ATMI's seven-member Board of Directors for a term not to exceed two years. Pursuant to the terms of the Merger Agreement, Advanced Technology is to indemnify and hold harmless each of the LSL stockholders against any and all losses arising out of (i) the conduct of the business of ownership of LSL after the Lawrence Effective Time, and (ii) any breach of the representations, warranties, or covenants of Advanced Technology contained in the Merger Agreement. In addition, the LSL stockholders are to indemnify and hold harmless LSL, Advanced Technology, Lawrence Merger Subsidiary, ATMI, and each of their officers, directors, employees, agents, representatives and affiliates (the "Company Indemnified Parties") against any and all losses arising out of any breach of the representations, warranties and covenants of LSL contained in the Merger Agreement. Each LSL stockholder is to indemnify severally the Indemnified Parties for each LSL stockholder's pro rata share of losses arising from any breach of the representations, warranties and covenants of LSL contained in the Merger Agreement with respect to taxes and environmental matters (the "Special Indemnities"). Other than with respect to the Special Indemnities and certain covenants, an indemnified party generally may not make any claim for indemnification after the first anniversary date of the Closing Date (as defined in the Merger Agreement), and no such claim may be brought after the date of issuance of the first independent audit report with respect to the financial statements of Advanced Technology after the Closing Date if such claim is of a type expected to be encountered in the course of an audit performed in accordance with generally accepted auditing standards. With respect to the Special Indemnities, the claims period is to extend for the statute of limitations applicable to the matters which are the subject of such claims. At the Lawrence Effective Time, five percent of the Lawrence Acquisition Consideration was placed in escrow as security for the indemnification obligations of LSL stockholders. See "Escrow Agreement" described below. Affiliate Agreement. Mr. Lawrence and ATMI have entered into an affiliate agreement (the "Affiliate Agreement") pursuant to which Mr. Lawrence has agreed that during the period commencing on the date of the Affiliate Agreement and ending at such time as financial results covering at least thirty days of combined operations of LSL and Advanced Technology have been published by ATMI, in the form of a quarterly earnings report, an effective registration statement filed with the SEC, a report to the SEC on Form 10-K, 10-Q or 8-K, or any other public filing or announcement which includes the combined results of operations, Mr. Lawrence will not engage in any sale, exchange, transfer, pledge, disposition of or grant of any option, the establishment of any "short" or put-equivalent position with respect to, or the entry into any similar transaction intended to reduce the risk of Mr. Lawrence's risk of ownership, or investment in, any of the following: (a) any shares of ATMI Common Stock Page 6 of 10 Pages --- --- which Mr. Lawrence acquires in connection with the Merger, or any securities which may be paid as a dividend or otherwise distributed thereon or with respect thereto or issued or delivered in exchange or substitution therefor (all such shares and other securities being referred to herein, collectively, as "Restricted Securities"), or any option, right or other interest with respect to any Restricted Securities, or (b) any other shares of ATMI Common Stock or other ATMI equity securities which Mr. Lawrence purchases or otherwise acquires after the execution of the Affiliate Agreement; provided, that Mr. Lawrence may exercise any conversion, liquidation preference or similar rights that he may have pursuant to ATMI' Certificate of Incorporation. Pursuant to the Affiliate Agreement, ATMI has agreed to publish, as promptly as practicable following the Merger, financial results covering at least 30 days of combined operations of Advanced Technology and LSL in the form of a quarterly earnings report, an effective registrations statement filed with the SEC, a report to the SEC on Form 10-K, 10-Q or 8-K, or any other public filing or announcement that includes the combined results of operations of Advanced Technology and LSL. In addition, Mr. Lawrence has represented that he has no present plan or intention to engage in a direct or indirect sale, exchange, transfer, redemption, disposition or conveyance or any transaction that would have the effect of reducing in any way Mr. Lawrence's risk of ownership by short sale or otherwise of the shares of ATMI Common Stock received by him in the Merger, except as contemplated by the Registration Rights Agreement (as defined below) and further, that he is not aware of, or participating in, any plan of any other stockholder of Advanced Technology to engage in a sale of ATMI Common Stock received in the Merger or otherwise. Registration Rights Agreement: ATMI has entered into a registration rights agreement (the "Registration Rights Agreement") with the LSL stockholders, including Mr. Lawrence, with respect to the shares of ATMI Common Stock acquired pursuant to the Merger (the "Lawrence Shares"). Pursuant to the Registration Rights Agreement, ATMI is to register for resale once, during each three-month period in the one-year period following the Lawrence Effective Time, a number of Lawrence Shares held by each holder that does not exceed one percent of the then outstanding ATMI Common Stock. Any holder that does not sell the full one percent in a given three-month period may cumulate the number of shares not so sold and sell such unsold shares in a subsequent three-month period. The Registration Rights Agreement also provides for (1) two demand registrations, if requested by the holders of at least 70% of the registrable shares, which right is exercisable between the first anniversary of the Lawrence Effective Time and the third anniversary of the Lawrence Effective Time; and (2) "piggyback" registration rights, exercisable prior to the fifth anniversary of the Lawrence Effective Time, on registration of shares by ATMI, for its own account or the account of other securityholders. ATMI is required to use diligent efforts to keep any such demand registration effective up to the third anniversary of the Lawrence Effective Time (subject to extension for any suspensions of sales or delays in registration imposed by ATMI). ATMI shall be permitted to delay the registration of Lawrence Shares during the one-year period following the Lawrence Effective Time and to require any such holders to delay any request for a demand registration (i) if ATMI is then proposing to register securities for its own account and pursues such proposed registration with diligence, provided that the holders are offered certain "piggyback" rights in connection therewith, or (ii) for a period of up to 60 days in any consecutive 12 months period, if in the good faith judgment of the Board of Directors of ATMI such registration would be seriously Page 7 of 10 Pages --- --- detrimental to ATMI and its stockholders. ATMI is required to bear substantially all registration and selling expenses (including certain fees of counsel to the selling stockholders but excluding underwriting discounts and commissions relating to the registrable shares) in connection with the registration of registrable shares in such registrations. ATMI and the LSL stockholders have agreed to indemnify the other against certain liabilities, including liabilities under the Securities Act of 1933, as amended, and to contribute to payments which the other may be required to make in respect thereof. The registration rights are transferable in limited circumstances and may be amended or waived only with the written consent of ATMI, and the holders of at least 70% of the Lawrence Shares. Escrow Agreement: Pursuant to an escrow agreement entered into by and among Advanced Technology, LSL, Lawrence Merger Subsidiary, ATMI, Security Trust Company, as escrow agent, and Lamonte H. Lawrence, as representative of the LSL stockholders (the "Escrow Agreement"), at the Lawrence Effective Time, five percent of the Lawrence Shares were placed in escrow as security for certain indemnification obligations of the LSL stockholders to Advanced Technology pursuant to the Merger Agreement. If the purchase price adjustment based upon any change in the combined net worth of LSL and LSLMS results in the issuance of additional shares to the LSL stockholders, certificates representing five percent of the additional shares of ATMI Common Stock to be delivered to the LSL stockholders will also be placed in escrow. All such shares are to be allocated among the LSL stockholders pro rata in accordance with their respective holdings of LSL Common Stock and are to be held and applied in accordance with the terms of the Merger Agreement and the Escrow Agreement. The escrow fund is required to remain in existence for a period of one year from the Lawrence Effective Time. Consulting Agreement: LSL and Lawrence Semiconductor Investments, Inc. ("LSI"), a corporation wholly owned by Lamonte H. Lawrence, have entered into a consulting agreement (the "Consulting Agreement"). The Consulting Agreement provides for the termination of Mr. Lawrence's employment by LSL, the cessation of LSL's obligations under any employment agreement, and the retention by LSL of LSI as an independent consultant for a three-year period (the "Consulting Term") on an independent contractor basis. Consulting services under the Consulting Agreement are provided exclusively by Mr. Lawrence. During each of the three twelve-month periods of the Consulting Term, Mr. Lawrence is to render consulting services as mutually agreed upon by LSI and LSL. In consideration of the consulting services being provided, LSL will pay LSI a per diem of $2,880, but in no event will the total fee payable to LSI be less than $250,000 for the first twelve-month period. Such minimum is approximately one-third of Mr. Lawrence's compensation from LSL and LSLMS in 1996, as Mr. Lawrence, on behalf of LSI, is expected to devote approximately one-third of his time during the year subsequent to the Merger to LSL-related matters. LSL is permitting LSI to become a participating employer in LSL's health insurance program, but only for the benefit of Mr. Lawrence. The Consulting Agreement may be terminated by LSI after one year upon thirty days' written notice to LSL, may only be terminated by LSL for cause and terminates automatically upon Mr. Lawrence's disability or death. Page 8 of 10 Pages --- --- NONCOMPETE AGREEMENT: Advanced Technology, Lawrence Merger Subsidiary, LSL and Lamonte H. Lawrence have entered into a noncompete agreement (the "Noncompete Agreement"). Pursuant to the Noncompete Agreement, Lamonte H. Lawrence has agreed that, for a period of the later of five years from the Lawrence Effective Time and three years from the expiration of the Consulting Agreement, he will not, directly or indirectly, engage or participate in, prepare or set up, assist or have any interest in any entity that engages in any activities in competition with LSL, or, for a period of five years from the consummation of the Merger, directly or indirectly hire or induce or encourage any employee or consultant who is then employed or retained by Advanced Technology, LSL or any of their subsidiaries to leave the employment of or terminate consultation with Advanced Technology, LSL or any of their subsidiaries, without the prior written consent of Advanced Technology.

The respective Boards of Directors of the Companies deem it advisable and in the best interests of their respective shareholders that Buyer acquire Lawrence by the merger of Buyer Sub with and into Lawrence upon the terms and subject to the conditions set forth in this Agreement (the "Merger"). The parties desire the Merger to be a tax-free reorganization under the Internal Revenue Code of 1986, as amended, and for such transaction to be accounted for as a pooling of interests. In consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein, the parties agree as follows: ARTICLE I THE MERGER 1.1 The Merger.

The Bylaws of the Surviving Corporation shall be the Bylaws of Lawrence, as amended in connection with the Merger to read in their entirety (other than with respect to the name of the corporation) as the Bylaws of Buyer Sub in effect immediately prior to the Effective Time, with such changes as Buyer may determine are necessary or proper to comply with Arizona law, until thereafter amended as provided by law. 2.3 Directors and Officers of the Surviving Corporation. (a) The directors of Buyer Sub at the Effective Time shall be the initial directors of the Surviving Corporation and shall hold office from the Effective Time until their respective successors are duly elected or appointed and qualified in the manner provided in the Articles of Incorporation and Bylaws of the Surviving Corporation, or as otherwise provided by law.

(b) Each share of common stock of Lawrence ("Lawrence Share") held in the treasury of Lawrence, if any, or by any subsidiary of Lawrence and each such Lawrence Share held by Buyer or any subsidiary of Buyer immediately prior to the Effective Time shall be canceled and retired and cease to exist, and no consideration shall be given in exchange therefor. 3.2 Exchange of Lawrence Shares. (a) Each Lawrence Share outstanding immediately prior to the Effective Time (other than Lawrence Shares canceled as set forth in Subsection 3.1(b) above, if any) shall, at the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive in shares of Buyer Common Stock, valued at the Average Closing Price (defined in Section 3.9 below), an amount equal to that described in Section 3.4 below divided by the number of Lawrence Shares outstanding immediately prior to the Effective Time (subject to adjustment as provided in Sections 3.4 and 3.5 and subject to reduction as provided in Article X and the Escrow Agreement), ninety-five percent (95%) of which amount prior to adjustment and reduction, if any (the "Preliminary Purchase Price Shares"), shall be issued to the holder thereof upon the surrender of the certificate formerly representing such Lawrence Share in accordance with this Section 3.2, and five percent (5%) of which amount prior to adjustment and reduction, if any (the "Indemnification Escrow Shares"), shall be held by the escrow agent (the "Escrow Agent") as provided for in Subsection 10.1(c) hereof. (b) Immediately following the Effective Time, each record holder (a "Shareholder") of any certificate or certificates which, immediately prior to the Effective Time, represented outstanding Lawrence Shares (the "Certificates") whose Lawrence Shares were converted into the right to receive a portion of the Purchase Price (defined below) shall be entitled to surrender his or its Certificates to Buyer for cancellation in exchange for the Shareholder's pro rata share of the Preliminary Purchase Price Shares, and Buyer hereby agrees to cause such Shareholder's pro rata share of the Preliminary Purchase Price Shares to be issued to such person at such time. If any Shareholder shall fail to surrender his or its Certificates promptly following the Effective Time, Buyer shall send to such Shareholder notice of the Merger and instructions for use in effecting the surrender of the Certificates in exchange for the Shareholder's pro rata share of the Purchase Price and the holder of such Certificates shall be entitled to receive in exchange therefor solely the Shareholder's pro rata share of the Purchase Price less any applicable stock transfer taxes, and such Certificates shall forthwith be canceled. No interest shall be paid or accrued for the benefit of holders of the Certificates on the consideration payable upon the surrender of the Certificates. It shall be a condition of exchange that the Certificate so surrendered shall be properly endorsed or otherwise in proper form for transfer. (c) From and after the Effective Time, there shall be no transfers on the stock transfer books of the Surviving Corporation of the Lawrence Shares which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for exchange, they shall be canceled and exchanged for a pro rata share of the Preliminary Purchase Price Shares in accordance with the procedures set forth in this Section and Section 3.4. (d) At or prior to the Effective Time of the Merger, Buyer shall deliver irrevocably to the Escrow Agent certificates evidencing the Indemnification Escrow Shares, together with appropriate stock powers executed by each Shareholder. As provided in Article X hereof, the Indemnification Escrow Shares shall be held in escrow (the "Indemnification Escrow") by the Escrow Agent. Income, dividends and earnings therefrom shall become funds of the Indemnification Escrow to be disbursed as provided in Article X of this Agreement and in the Escrow Agreement. (e) Notwithstanding the foregoing, any Lawrence Shares issued and outstanding immediately prior to the Effective Time which are held by Shareholders who have not voted such shares in -3- favor of the Merger and who have complied with all other relevant provisions of Chapter 13 of the ABCA (the "Dissenting Shares") shall not be converted into shares of Buyer Common Stock in the manner contemplated by Section 3.2(a) above, and the rights of holders of the Dissenting Shares shall be governed by the provisions of Chapter 13 of the ABCA; provided, however, that Shareholders that own in the aggregate no greater than five percent (5%) of the issued and outstanding Lawrence Shares who have not voted such shares in favor of the Merger (the "Electing Shares") may elect, in lieu of following the provisions of Chapter 13 of the ABCA, to receive from Buyer the Average Closing Price for each share of Buyer Common Stock to which such Shareholder would have been entitled had such Shareholder voted in favor of the Merger. Lawrence agrees to notify its Shareholders in writing prior to the time the Merger is submitted to them for a vote at any Shareholders' meeting or otherwise, of the foregoing election. To be effective, such election must be made in writing to Lawrence and Buyer within five (5) days of the date of such Shareholder meeting or other submission for a vote. (f) Notwithstanding the foregoing, if the closing of the transactions contemplated by the ADCS Merger Agreement shall occur on or before the Effective Time, in lieu of Buyer Common Stock each Lawrence Share shall be converted into the right to receive Holdings Common Stock in the same ratio as such Lawrence Shares would have been converted into shares of Buyer Common Stock. In such event, all references to "Buyer Common Stock" in this Agreement (other than in Article IV) shall be deemed to be references to "Holdings Common Stock," unless the context clearly requires otherwise. The parties shall modify the ancillary agreements to be entered into as of the Effective Time as appropriate to reflect such change. 3.3 No Further Rights in Lawrence Shares. All shares of Buyer Common Stock received by any Shareholder pursuant to this Agreement shall be deemed to have been delivered and received in full satisfaction of all rights pertaining to such Shareholder's Lawrence Shares. At the Effective Time, the holders of certificates representing outstanding Lawrence Shares shall cease to have any rights with respect to such shares (other than such rights as they may have as dissenting shareholders under the ABCA), and their sole right shall be to receive their pro rata share of the Purchase Price. Dissenting shareholders shall have the rights accorded by the ABCA. 3.4 The Purchase Price. The aggregate merger consideration for all outstanding Lawrence Shares shall be that number of shares of Buyer Common Stock, valued at the Average Closing Price, having a value equal to Eighty Million Dollars ($80,000,000) (the "Closing Price") plus an amount (the Adjustment Amount, defined in Subsection 3.4(g) below), which may be a positive or a negative number, as determined below, minus the amount of Two Million Dollars ($2,000,000) required to be paid by LSL to Applied Materials, Inc. ("Applied") pursuant to LSL's settlement of its litigation with Applied (as described in Section 5.7 and Schedule 5.7), minus any amounts owed to LSL by any related parties as set forth in Schedule 5.26 and minus the cost to LSL of any payment required to be made by LSL prior to the Effective Time to any third party in connection with any other transaction contemplated by LSL, including any payment in the nature of a required "break-up" fee (the "Specified Amount"), subject to further reduction as provided in Article X and the Escrow Agreement ("Purchase Price"). (a) Within sixty (60) days after the Effective Time, the Representative (defined in Subsection 3.6(a)(xix) below) shall cause to be delivered to Buyer a combined balance sheet of Lawrence as of the close of business at the Effective Time without inclusion of Lawrence Semiconductor Research Laboratories, Inc. ("LSRL") or Lawrence Semiconductor Investments, Inc. ("LSI") (the "Effective Time Balance Sheet") together with the related combined statements of income, shareholders' equity and cash flows for the time period from January 1, 1997 to the Effective Time (the "Related Effective Time Statements") audited by Lawrence's current independent accountants, which audit shall include a physical inventory that representatives of Buyer may observe. The Effective Time Balance Sheet and the Related Effective Time Statements shall be prepared in accordance with generally accepted accounting principles applied on a basis consistent with past practice, and the Effective Time Balance Sheet shall fairly present the assets and liabilities and financial condition of Lawrence at the Effective Time, including the tax savings to LSL as a result of the payment of the Specified Amount, but not including the actual amount of the Specified Amount. The reasonable cost of the audit pursuant to this Subsection 3.4(a) shall be borne by the Surviving Corporation. After the Effective Time, Buyer agrees to give the Representative and -4- Lawrence's current accountants reasonable access to Lawrence's books and records and to make available to such parties such employees of Lawrence and the Surviving Corporation as may be reasonably necessary in connection with the preparation of the Effective Time Balance Sheet. (b) The Effective Time Balance Sheet shall become final and binding on Lawrence and Buyer thirty (30) days after its delivery to Buyer, unless Buyer or Representative gives written notice to the other of his or its disagreement with respect to any item included in such Effective Time Balance Sheet. During said thirty (30) day period, Representative, Buyer and Buyer's representatives shall be given reasonable access to all of the working papers of Lawrence's current independent accountants for the purpose of its review of the Effective Time Balance Sheet. The party making the objection shall notify the other party in writing by the end of such thirty (30) day period of any objection it may have to the Effective Time Balance Sheet, which objection shall identify the basis of such objection and any adjustments to the Effective Time Balance Sheet that it proposes be made (the "Proposed Adjustments"). (c) If written notice of objections to the Effective Time Balance Sheet is given within the period specified in Subsection 3.4(b) above, the party receiving the notice shall notify the party proposing the Proposed Adjustment of his or its approval or disapproval of the Proposed Adjustments to the Effective Time Balance Sheet contained in such written objection within thirty (30) days of his or its receipt of such written objection. If the party receiving the notice shall fail to notify the party proposing the Proposed Adjustments in writing of his or its disapproval of the Proposed Adjustments within said thirty (30) day period, such Proposed Adjustments shall be made to the Effective Time Balance Sheet, and the Effective Time Balance Sheet, as so adjusted, shall be final and binding upon all parties. If Representative and Buyer cannot reach agreement with respect to the Proposed Adjustments and the objections thereto within thirty (30) days of the date of receipt of the notice of the Proposed Adjustments (or such longer period as may be acceptable to Buyer and Representative), Buyer and Representative shall submit the Proposed Adjustments in dispute to the Arbitrating Accountants (defined in Subsection 3.4(f) below) for resolution. The Arbitrating Accountants shall have no authority (i) to decide any issues related to the Effective Time Balance Sheet other than those issues expressly referred to them for arbitration pursuant to the terms hereof, or (ii) to determine that any disputed Proposed Adjustment shall be made in excess (negative or positive) of the amount originally proposed by Buyer or Representative. (d) If the parties submit a dispute to the Arbitrating Accountants, the parties shall instruct the Arbitrating Accountants to resolve the disputed Proposed Adjustments within thirty (30) business days after such Proposed Adjustments are submitted to them, and such resolution shall be final and binding upon all parties hereto. Upon such resolution, the adjustments to the Effective Time Balance Sheet determined by the Arbitrating Accountants shall be made and the Effective Time Balance Sheet, as so adjusted, shall be final and binding upon all parties. (e) The fees and expenses of the Arbitrating Accountants shall be paid by Buyer; provided that the portion of such fees and expenses equal to the lesser of (i) 100% or (ii) the percentage obtained by dividing (i) the aggregate dollar amount of the adjustments to the Effective Time Balance Sheet determined under Subsection 3.4(d) by (ii) the aggregate dollar amount of the disputed Proposed Adjustments shall be reimbursed to Buyer from the Indemnification Escrow. Representative shall have the right to retain legal counsel of its choosing with regard to any dispute over the Adjustment Amount (defined in Subsection 3.4(g) below), including Polese, Pietzsch, Williams & Nolan, P.A., and the costs and expenses of such representation shall be paid from the Adjustment Amount if that amount is a positive number and sufficient to so pay the costs and expenses, or otherwise from the Indemnification Escrow. (f) The "Arbitrating Accountants" shall be a "Big Six" accounting firm that is mutually agreed to by Buyer and Representative. (g) Upon the Effective Time Balance Sheet (including any adjustments) becoming final and binding on all parties as set forth above, the Adjustment Amount shall be determined by the Buyer. The "Adjustment Amount" shall equal the difference between (x) the Net Worth (defined below) as shown on the Effective Time Balance Sheet and (y) the Net Worth as shown on Lawrence's unaudited balance sheet at December 31, 1996 without inclusion of LSRL or LSI. "Net Worth" shall equal the amount -5- by which assets exceed liabilities. Buyer and Representative shall provide notice to the Shareholders of the Adjustment Amount and final Purchase Price within two (2) business days of such amounts becoming final. 3.5 Adjustment of Purchase Price. If the Adjustment Amount is a positive number, ninety-five percent (95%) of such amount shall be paid by Buyer to Shareholders pro rata in shares of Buyer Common Stock valued at the Average Closing Price and five percent (5%) to Escrow Agent (the "Escrow Adjustment") by delivering appropriate certificates evidencing such shares within ten (10) business days of determination. If the Adjustment Amount is a negative number, it shall be paid to Buyer in shares of Buyer Common Stock valued at the Average Closing Price from the Indemnification Escrow within ten (10) business days of receipt of notice of determination. 3.6 Closing.

(c) By voting to approve this Agreement or by surrendering his or its Certificate(s) evidencing Lawrence Shares at Closing, each Shareholder, other than Shareholders who have perfected dissenter rights under the ABCA, acknowledges and agrees that (i) the consideration to which such Shareholder is entitled hereunder is subject to adjustment as contemplated in Articles III and X, (ii) the Indemnification Escrow Shares and the Escrow Adjustment shall be placed in the Indemnification Escrow provided for in an Escrow Agreement to be entered into, as of the Effective Time, in the form of Exhibit "D" attached hereto and (iii) the Escrow Agent shall be, and is hereby, authorized from time to time to transfer all or any portion of the amounts so deposited in satisfaction of the indemnity obligation and as otherwise provided pursuant to Articles III and X and as contemplated in the Escrow Agreement. Except as provided in Section 10.5, the Indemnitees agree to look solely to the Indemnification Escrow for recourse in the event of a breach of any representation or warranty or covenant of Lawrence contained in this Agreement and will not look directly to any Shareholder or Shareholders for any indemnification hereunder. (d) If any Indemnitee shall have any liquidated claim of indemnification pursuant to Subsection 10.1(b), it shall promptly request that Buyer give written notice thereof to the Representative and the Escrow Agent, including a brief description of the facts upon which such claim is based and the amount thereof. Any Indemnitee may also request that Buyer provide written notice to the Representative and the Escrow Agent of any unliquidated claim of indemnification pursuant to Subsection 10.1(b), including a brief description of the facts upon which such claim is based and a demand for a reserve -30- amount to be created in respect of such claim. Any claim made by any Indemnitee for Losses that are unliquidated shall not be paid, but shares of Buyer Common Stock valued at the Average Closing Price equal to such claim shall be held in the Indemnification Escrow until such Losses are fully liquidated. Notwithstanding the foregoing, no amount will be delivered to an Indemnitee pursuant to a written claim notice (with respect to either a liquidated or unliquidated claim) pursuant to Subsection 10.1(b) above and Section 10.5 below unless, and then only to the extent that, the aggregate amount of Losses sustained by Indemnitees as a group and as to which written claim notices have been given exceeds Two Hundred Fifty Thousand Dollars ($250,000) (taking into account any reduction of prior noticed claims resulting from the dispute resolution procedures of Section 10.2 below). (e) If the Representative shall notify the Escrow Agent in writing (within thirty (30) days of delivery to the Escrow Agent by Buyer of a written notice of claim for indemnification) of his objection to a claim of indemnification or a demand for the creation of a reserve against the Indemnification Escrow for any unliquidated claim (or the amount thereof), the Escrow Agent shall hold the disputed amount of funds in the Indemnification Escrow until the rights of the Shareholders and the Indemnitees with respect thereto have been agreed upon between the Representative and the claiming Indemnitee. In the event such an agreement is reached, the claiming Indemnitee shall request Buyer to provide to the Escrow Agent a written notice signed by the Representative in the form specified in the Escrow Agreement. If no such agreement has been reached, either the Indemnitee or the Representative may, not earlier than thirty (30) days after the date of the initial claim notice, submit the dispute to confidential, binding arbitration in New York, New York before a panel of three arbitrators, one each to be selected by Buyer and the Representative, and the third to be selected by the other two arbitrators, pursuant to the procedures and rules for commercial arbitration of the American Arbitration Association. The Escrow Agent may rely on the order or other determination of such arbitrators. If such arbitrators shall determine that any part of the Indemnification Escrow is to be delivered to an Indemnitee or is to be set aside in a reserve for any unliquidated claim, the Escrow Agent shall promptly following receipt of a copy of such determination establish such reserve or deliver to such Indemnitee the lesser of (i) the amount of the claim or claims as awarded to the Indemnitee to be satisfied, subject to the limitation set forth in Subsection 10.1(d) or (ii) the entire amount remaining in the Indemnification Escrow. Any disputed amounts not awarded to the Indemnitee shall promptly be transferred to the unreserved portion of the Indemnification Escrow. Buyer and the Representative shall bear their respective costs and expenses of any such arbitration. Buyer expressly acknowledges that Polese, Pietzsch, Williams & Nolan, P.A. can continue to represent Representative in any such dispute and hereby waives any conflict of interest which might otherwise exist. (f) Promptly after the Termination Date, the Escrow Agent shall distribute to the Shareholders on a pro rata basis all remaining unreserved amounts in the Indemnification Escrow, less an amount equal to the dollar amount of all claims pursuant to Subsection 10.1(c) that are still in process and (i) that are then-payable liquidated claims, (ii) for which a reserve established pursuant to Subsection 10.1(d) then exists, or (iii) that are still in the process of resolution pursuant to this Section 10.1. No new claims may be brought under this Section 10.1 after the Termination Date. (g) After the Termination Date, (i) as each matter referred to in Subsection 10.1(f) is resolved or otherwise concluded and (ii) as each undisputed unliquidated claim which remains unliquidated as of the Termination Date is liquidated, the Escrow Agent shall distribute to the Shareholders their respective pro rata portion of the Escrow Fund (as defined in Exhibit D) then determined by the Escrow Agent to be free of any rights of any Indemnitee and, when all such matters are resolved and such claims are liquidated, the obligations under Subsection 10.1(b) hereof shall terminate. The Indemnification Escrow shall be terminated when all of the Escrow Fund in the Indemnification Escrow shall have been disbursed by the Escrow Agent in accordance with the provisions hereof and the Escrow Agreement. (h) In taking any action whatsoever hereunder, the Representative shall be protected in relying upon any notice, paper or other document reasonably believed by him to be genuine, or upon any evidence reasonably deemed by him to be sufficient. The Representative may consult with counsel in connection with his duties hereunder and shall be fully protected in any act taken, suffered or permitted by him in good faith or in accordance with the advice of counsel. The Representative shall not be liable to the -31- Shareholders for the performance of any act or the failure to act so long as he acted or failed to act in good faith within what he reasonably believed to be the scope of his authority and for a purpose which he reasonably believed to be in the best interests of the Shareholders. 10.2 Procedure. In the event that, at any time or from time to time after the Effective Time, a person indemnified under Section 10.1 or 10.3 (an "Indemnified Party") shall sustain a loss of any nature whatsoever against which such Indemnified Party is indemnified under this Agreement, such Indemnified Party shall notify the party hereto obligated to provide such indemnification (the "Indemnitor") of any such loss so sustained. If Indemnitor is Buyer, Indemnitor shall within thirty (30) days after transmittal of such notice pay to such Indemnified Party the amount of such loss so sustained, subject to the right to contest any claim. If Indemnitor is the Shareholders, payment shall be governed by the Escrow Agreement. The Indemnified Party shall promptly notify the Indemnitor of the existence of any claim, demand, or other matter involving liabilities to third parties to which the Indemnitor's indemnification obligations would apply and shall give the Indemnitor (acting through the Representative if Indemnitor is the Escrow Agent) a reasonable opportunity to defend the same or prosecute such action to conclusion or settlement satisfactory to the Indemnified Party at Indemnitor's own expense and with counsel of Indemnitor's selection (who shall be approved by Indemnified Party, which approval shall not be unreasonably withheld); provided that the Indemnified Party shall at all times also have the right to fully participate in the defense at its own expense. If the Indemnitor shall, within a reasonable time after said notice, fail to defend, the Indemnified Party shall have the right, but not the obligation, to undertake the defense of, and to compromise or settle (exercising reasonable business judgment) the claim or other matter on behalf, for the account, and at the risk and expense of Indemnitor. Except as provided in the preceding sentence, the Indemnified Party shall not compromise or settle the claim or other matter without the prior written consent of the Indemnitor. If the claim is one that cannot by its nature be defended solely by the Indemnitor, the Indemnified Party shall make available all information and assistance that the Indemnitor may reasonably request; provided that any associated expenses shall be paid by the Indemnitor. If the Losses relate to a Loss or demand asserted by a third party, the Indemnified Party and Indemnitor shall jointly control the defense and settlement thereof and any settlement shall require the prior written consent of both parties, which consent shall not be unreasonably withheld. 10.3 Buyer's Indemnification. Buyer agrees to indemnify and hold Shareholders harmless from and against any and all Losses which may accrue or be sustained by Shareholders arising out of or as a result of (a) the conduct of the business or ownership of Lawrence or the Surviving Corporation after the Effective Time, or (b) any of the warranties, representations or covenants of Buyer contained in this Agreement being incorrect, untrue or breached. The term "Losses" for purposes of this Section 10.3 shall not include any loss resulting from a diminution in the value of Buyer Common Stock received in the Merger. Buyer also agrees to indemnify and hold Lamonte H. Lawrence, LSI and LSRL harmless from and against any and all losses which may accrue or be sustained by Lamonte H. Lawrence, LSI and/or LSRL arising out of or as a result of the parties' inability to obtain the Releases of all of the Guarantees and a breach by Lawrence of the guaranteed obligation. Notwithstanding the foregoing, no amount will be paid pursuant to a written claim notice for indemnification pursuant to this Section 10.3 (with respect to either a liquidated or unliquidated claim) unless, and then only to the extent that, the aggregate amount of Losses sustained by Shareholders, Lamonte H. Lawrence, LSI, or LSRL as a group and as to which written claim notices have been given by any of Shareholders, Lamonte H. Lawrence, LSI and/or LSRL to Buyer exceeds Two Hundred Fifty Thousand Dollars ($250,000). 10.4 Contest; Challenge. If Indemnitor contests or challenges any claim or action asserted against Indemnified Party referred to in this Article, it shall do so at its own cost and expense, holding Indemnified Party harmless from all costs, fees, expenses, debts, liabilities and charges in connection with such contest; shall diligently defend against any such claim; and shall hold Indemnified Party's business and assets free and harmless from any attachment, execution, judgment, lien or other legal process. -32- 10.5 Special Indemnity. (a) By voting to approve this Agreement or by surrendering his or its Certificate(s) evidencing Lawrence Shares at Closing, each Shareholder, other than Shareholders who have perfected dissenter rights under applicable law, severally and not jointly, agrees to defend and indemnify the Indemnitees against and hold each of them harmless from each Shareholder's Pro Rata Portion (defined below) of any and all Losses which any such Indemnitee may suffer or incur by reason of the inaccuracy or breach of any of the representations, warranties and covenants of Lawrence contained in Section 5.13 or Section 5.15 of this Agreement or any documents, certificates or agreements delivered pursuant hereto. The right of Indemnitees to indemnification under this Section 10.5 shall apply only to those claims for indemnification, notice of which is given pursuant to this Agreement to the Shareholders on or before the running of the applicable statute of limitations; provided that such limitations shall not apply to any claim resulting from fraud or intentional misrepresentation. As used herein, "Pro Rata Portion" shall mean with respect to each Shareholder his or its percentage ownership of Lawrence after the merger of Lawrence and LSLMS and immediately prior to the Effective Time. (b) Each Shareholder, other than Shareholders who have perfected dissenter rights under applicable law, acknowledges and agrees that its obligations under this Section 10.5 are recourse obligations enforceable against it personally. Each Shareholder waives any right to require Indemnitees to (i) proceed against any person or entity including any other Shareholder, (ii) proceed against or exhaust any collateral or security or any part thereof, or (iii) pursue any other remedy in its power, and waives any defense arising by reason of any inability of any other obligor to pay or any defense based on bankruptcy or insolvency or other similar limitations on creditors' remedies with respect to any other person. Indemnitees agree to use their reasonable efforts to collect any Losses from any available insurer or third party indemnitors before collecting from the Shareholders or the Escrow Fund, and to use their reasonable efforts to collect from the Escrow Fund before collecting from the Shareholders; however, nothing in the foregoing clauses shall preclude any claiming party from filing a claim against either the Shareholders or the Escrow Fund from the outset. If any amounts are recovered from an insurer or third party after payment to an Indemnitee of all Losses suffered or incurred by it, such Indemnitee shall promptly pay over to the indemnifying party the excess amount so recovered. Any claims against the Escrow Fund shall be subject to the procedures set forth in Section 10.2. (c) Notwithstanding anything to the contrary in this Article X, including without limitation any provision of Section 10.2, the Representative shall have sole and complete power and authority (i) to settle any matter which is the subject of a claim for indemnification pursuant to this Section 10.5 which can be settled solely with the payment of money (ii) to conduct and settle any litigation which is the subject of a claim for indemnification pursuant to this Section 10.5 which can be settled solely with the payment of money, and (iii) to control and direct, subject to Buyer's approval, which shall not be unreasonably withheld or delayed, any and all remediation or other clean-up or mitigation of any environmental condition which is the subject of a claim for indemnification pursuant to this Section 10.5. 10.6 Waiver. Each Shareholder irrevocably, knowingly and voluntarily waives any claim which such Shareholder now has or may hereafter have against Indemnitees, the Escrow Fund, and any collateral or security whatsoever now or hereafter held by Indemnitees, arising out of or resulting from payment or demand for payment of Losses, whether such claim is characterized as a claim for contribution, indemnification, subrogation or otherwise; provided that the foregoing shall not limit the Shareholders' ability to challenge the propriety of any claim for Losses made by Indemnitee(s). 10.7 Average Closing Price. To the extent that the Indemnitees make a claim against the Escrow Fund pursuant to the Escrow Agreement, and such claim is paid in shares of Buyer Common Stock, then for purposes of such payment, the shares of Buyer Common Stock shall be valued at the Average Closing Price. 10.8 Reduction of Losses. The amount of any Losses for which indemnification is provided under this Article X shall be reduced to take account of any net tax benefit realized arising from the -33- incurrence or payment of any such Losses or from the receipt of any such indemnification payment and shall be reduced by the insurance proceeds received and any other amount, if any, recovered from third parties by an Indemnitee (or any of their affiliated entities) with respect to any Losses. The Indemnified Party shall be obligated to use commercially reasonable efforts to prosecute diligently and in good faith claims under any applicable insurance policies (including, without limitation, any applicable insurance policies maintained by either of the Companies or the Surviving Corporation) and against other third parties who may be responsible for Losses prior to collecting indemnification for such Losses under this Article X. If any Indemnitee (or any of their affiliated entities) shall have received any payment pursuant to this Article X with respect to any Loss and shall subsequently have received insurance proceeds or other amounts with respect to such Loss, then such Indemnitee (or its affiliated entities) shall promptly pay over to the Representative (for distribution pro rata to the Shareholders) the amount so recovered but not in excess of the amount previously so paid by the Shareholders. 10.9 Remedies. The sole and exclusive remedy of any party to this Agreement for any claim arising under this Agreement against any other party hereto shall be the indemnification provided in this Article X, and each party agrees that it will not pursue any other remedy, except that either party may seek specific performance or injunctive relief.

The legends set forth in paragraphs 6 and 7 above shall be removed and any stop transfer instructions terminated upon delivery of substitute certificates without such legend if the undersigned shall have delivered to Holdings a copy of a letter from the staff of the SEC, or an opinion of counsel in form and substance reasonably satisfactory to Holdings, to the effect that such legend is not required for purposes of the Securities Act. 9.

(a) If any Registrable Securities were issued to the Stockholders pursuant to the Merger Agreement without registration under the Securities Act, the Company shall use its reasonable best efforts to register Registrable Securities under the Securities Act for sale as follows: (i) the Company will register once, during each three-month period in the one-year period commencing on the Closing Date, that number of shares of Registrable Securities held by each such Stockholder that does not exceed, for each such three-month period, one percent (1%) of the then outstanding Company Common Stock; provided that the number of shares permitted to be sold in such three-month periods shall be cumulative, and any Stockholder that does not sell the full one percent (1%) in a given three-month period may cumulate the number -2- of shares not so sold and sell such unsold shares in a subsequent three- month period; (ii) from the first anniversary of the Closing Date until the third anniversary of the Closing Date (as may be extended pursuant to Section 3(c) below), the Company will, upon a request from Stockholders holding at least 70% of the Registrable Securities initially issued pursuant to the Merger Agreement, register any Registrable Securities on Form S-3 (or any successor form) or, if such form is unavailable to the Company, on such other form as is available to the Company; provided each such request relates to the registration of shares having a market value of at least $5,000,000 if registered on Form S-1 or $1,000,000 if registered on Form S-3; and (iii) the Company shall use diligent efforts: (A) in the case of the first registration pursuant to Section 3(a)(i), to cause such registration statement to become effective under the Securities Act not later than the business day next following the expiration of the Pooling Period; (B) in the case of each other registration pursuant to Section 3(a)(i), to cause such registration statement to become effective under the Securities Act not later than the first day of each successive three-month period; and (C) in the case of the first registration requested pursuant clause (a)(ii) of this Section 3, if such request is delivered at least 45 days prior to the first anniversary of the Closing Date, to cause such registration statement to become effective under the Securities Act not later than the business day next following the first anniversary of the Closing Date. (b) If the Registrable Securities were issued to the Stockholders pursuant to a registration statement under the Securities Act, then, from the first anniversary of the Closing Date until the third anniversary of the Closing Date (as may be extended pursuant to Section 3(c) below), Stockholders holding at least 70% of the Registrable Securities initially issued pursuant to the Merger Agreement may request the Company to register up to 50% of the Registrable Securities issued to such Stockholders pursuant to the Merger Agreement on Form S-3 (or any successor form) or, if such form is unavailable to the Company, on such other form as is available to the Company; provided, however, that each such request relates to the registration of shares having a market value of at least $5,000,000 if registered on Form S-1 or $1,000,000 if registered on Form S-3; provided, further, however, that the maximum number of Registrable Securities which the Company is obligated to register for a Stockholder under this Section 3(b) shall be reduced to the extent that such Stockholder has sold Registrable Securities pursuant to Rule 145(d) or otherwise. (c) No registration pursuant to Section 3(a)(i) or request made under Section 3(a)(ii) or Section 3(b) shall require a registration statement requested therein to become effective (i) prior to the effective date of a registration statement filed by the Company covering a firm commitment underwritten public offering of the Company Common Stock being sold for the account of the Company if the Company shall have given written notice in the manner provided in Section 4 below of such registration statement to the -3- Stockholders prior to the Company's obligation to register under Section 3(a)(i) or the receipt of a demand notice from the Holders pursuant to this Section 3 and shall have thereafter pursued the preparation, filing and effectiveness of such registration statement with diligence (it being understood by such Stockholders that advance notice of the pendency of such registration may be material, non-public information); or (ii) if the Company shall furnish to the Stockholders a certificate signed by the President of the Company and prepared in good faith stating that, in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such registration to be effected at such time, in which event the Company shall have the right to defer the filing of the registration statement for a period of not more than sixty (60) days after receipt of the request for registration, which right may not be exercised by the Company on more than one occasion during any period of 12 consecutive months; provided, however, that if the obligation of the Company under Section 3(a)(i) is so suspended by the Company pursuant to clause (i) above, such suspension shall be effective only if the Stockholders are permitted to include in the registration statement filed by the Company, in addition to any shares included in such registration pursuant to Section 4 of this Agreement, no less than the number of shares which they would have been permitted to sell pursuant to Section 3(a)(i) during the period of such suspension and, if such Company registration involves an underwriting, any lock-up period requested by the managing underwriter. If the right of the Stockholders to request a registration is so suspended by the Company pursuant to clause (i) or (ii) above, then the periods specified in Sections 3(a)(ii) and 3(b) shall be increased by one day for each day such right is suspended. (d) Following receipt of any notice under this Section 3, the Company shall immediately notify all Stockholders from whom notice has not been received and shall use its reasonable best efforts to register under the Securities Act, for public sale in accordance with the method of disposition specified in such notice from requesting Stockholders, the number of Registrable Securities specified in such notice subject to the limitations specified in this Section 3 (and in all notices received by the Company from other Stockholders within 30 days after the giving of such notice by the Company). If such method of disposition shall be an underwritten public offering, the Company may designate the managing underwriter of such offering, subject to the approval of the Stockholders holding a majority of the Registrable Securities to be sold in such offering, which approval shall not be unreasonably withheld or delayed. The Company shall be obligated to register Registrable Securities pursuant to Section 3(a)(i) on four occasions only, pursuant to Section 3(a)(ii) on two occasions only, and pursuant to Section 3(b) on one occasion only; provided, however, that such obligation shall be deemed satisfied only when a registration statement, which covers all Registrable Securities specified in notices received as aforesaid and with respect to which the request for registration has not been withdrawn and provides for sale of such shares in accordance with the method of disposition specified by the requesting Stockholders, shall have become effective and, if such method of disposition is a firm commitment underwritten public offering, all such shares shall have been sold pursuant thereto; provided further, if, on any one occasion, the Stockholders exercise a demand right and subsequently inform the Company in writing that (i) they desire to withdraw such registration or (ii) they are unable to sell in -4- excess of 50% of the Registrable Shares covered by such registration statement due to a deterioration in market conditions or other bona fide reason and the Stockholders reimburse the Company for all Registration Expenses incurred by the Company in connection with such terminated registration, then the Stockholders shall be deemed not to have exercised the demand right under this Agreement and shall be permitted to exercise such right in accordance with the terms of Section 3(a) of this Agreement on one additional occasion; and provided, further, that if such withdrawal or inability to sell in excess of 50% of such shares is due to the discovery by the Stockholders of a material adverse change in the condition, business or prospects of the Company as determined by the managing underwriter(s) of the related offering, if any, or by Stockholders holding at least 70% of the Registrable Securities proposed to be included in the registration, if there shall be no underwriters, from that known to any of the Stockholders at the time of their request and the Stockholders shall have withdrawn such request or terminated sales promptly following the disclosure by the Company of such material adverse change, then the Stockholders shall not be required to pay such expenses and shall retain their right to again request such registration in the future. (e) The Company shall be entitled, upon written notice to the Holders within 30 days after receipt of their request to effect a registration pursuant to this Section 3, to include in any registration statement referred to in this Section 3, for sale in accordance with the method of disposition specified by the requesting Stockholders, shares of Company Common Stock to be sold by the Company for its own account, except as and to the extent that, in the opinion of the managing underwriter (if such method of disposition shall be an underwritten public offering), such inclusion would adversely affect the marketing of the Registrable Securities to be sold. In the event the Company exercises such right and includes shares in such registration statement equaling more than 50% of the shares included in such registration, such registration shall be deemed to be Company-initiated registration and the Holders shall not be deemed to have exercised a demand right under Section 3. 4. Piggy-Back Registration. (a) Notice. If the Company at any time after the expiration of the Pooling Period proposes to register, other than pursuant to Section 3 hereof, any of its securities under the Securities Act for sale to the public, whether for its own account or for the account of securityholders other than the Holders or both (except for registrations on Form S-4 or S-8 or another form not available for registering the Registrable Securities for sale to the public), each such time it will give written notice to all Holders of its intention to do so and of the Holders' rights under this Section 4. Upon the written request of any such Holder, received by the Company within 30 days after the giving of any such notice by the Company, to register any of the Holder's Registrable Securities, the Company will cause the Registrable Securities as to which registration shall have been so requested to be included in the securities to be covered by the registration statement proposed to be filed by the Company, all to the extent requisite to permit the sale or other disposition by the Holder (in accordance with the Holder's written request) of such Registrable Securities so registered. -5- (b) Underwriting. If (i) a registration described in this Section 4 involves an underwritten offering of the securities so being registered to be distributed (on a firm commitment basis) by or through one or more underwriters, (ii) the Registrable Securities so requested to be registered for sale for the account of the Holders are also to be included in such underwritten offering, and (iii) the managing underwriter of such underwritten offering shall inform the Company and the Holders by letter of its belief that the distribution of all or a specified number of the Registrable Securities requested to be included concurrently with the securities being distributed by such underwriters would interfere with the successful marketing of the securities being distributed by such underwriters, then the Company may, upon written notice to all Holders, reduce (if and to the extent stated by such managing underwriter to be necessary to eliminate such effect) the number of the Registrable Securities requested to be included so that the resultant aggregate number of the Registrable Securities requested to be included that will be included in such registration shall be equal to the number of shares stated in such managing underwriter's letter; provided, however, that the priority in such registration shall be as follows: (i) first, securities offered for the account of the Company or, if such registration is for a securityholder exercising a contractual request for registration, then securities offered for the account of such securityholder, (ii) second, the Registrable Securities and the securities of other securityholders, if any, who are entitled by contract to have such securities included in such registration, pro rata based on the number of shares of Company Common Stock then held, and (iii) third, all other securities proposed to be registered. (c) Other Matters. Notwithstanding the foregoing provisions, the Company may withdraw or delay any registration statement referred to in this Section 4 without thereby incurring any liability to the Holders. Any such withdrawal or delay shall be without prejudice to the rights of the Holders under Section 3 hereof. No registration effected under this Section 4 shall relieve the Company of its obligations under Section 3 hereof. 5. Termination of the Company's Registration Obligations. The Company's registration obligations under (i) Section 3 shall terminate three years after the Closing Date (subject to extension pursuant to Section 3(c) and the penultimate paragraph of Section 6) and (ii) Section 4 shall terminate five years after the Closing Date. In addition, the Company shall not be required to effect a registration pursuant to Section 3 or 4 hereof for any Holder desiring to participate in such registration or to maintain the effectiveness of any registration statement for any Holder who, in any such case, may then dispose of all of such Holder's shares of Registrable Securities pursuant to Rule 144 within the three-month period following such proposed registration; provided, however, no termination of the Company's registration obligations shall be deemed to affect the parties' obligations under Sections 8, 9 and 10 of this Agreement, which Sections shall survive the termination of such registration obligations. 6. Registration Procedures. If and whenever the Company is required by the provisions of Section 3 or 4 to effect the registration of any Registrable Securities under -6- the Securities Act, the Company shall, as expeditiously as possible and until the Company's registration obligations terminate pursuant to Section 5 hereof: (a) prepare and file with the Commission the requisite registration statement to effect such registration and thereafter use diligent efforts to cause each such registration statement to become and remain effective until the earlier of (A) the date on which all of the Registrable Securities covered by such registration statement have been disposed of by the Holder or Holders thereof in accordance with the intended methods of disposition thereof described in the registration statement (each Holder or Holders thereof hereby agreeing to inform the Company upon the completion of the disposition of their respective Registrable Securities); or (B) the expiration of the following periods: (i) in the case of any Holder, the period after which the Company's registration obligations terminate as to such Holder pursuant to Section 5 hereof; and (ii) in the case of a registration pursuant to Section 4 hereof, 180 days after the effective date of such registration statement (as the periods specified in clauses (i) and (ii) above may be extended pursuant to the penultimate paragraph of this Section 6);

(d) use diligent efforts to register or qualify all Registrable Securities covered by such registration statement under such other securities laws or blue sky laws of such jurisdictions as any Holder thereof and any underwriter thereof shall reasonably request, and to keep such registrations or qualifications in effect for so long as such registration statement remains in effect, and take any other action which may be reasonably necessary or advisable to enable such Holder and underwriter to consummate the disposition in such jurisdictions of the Registrable Securities owned by such Holder, except that the Company shall not for any such purpose be required to qualify generally to do business as a foreign corporation in any jurisdiction wherein it would not but for the requirements of this Section 6(d) be obligated to be so qualified or to consent to general service of -7- process in any such jurisdiction (unless the Company is subject to service in such jurisdiction and except as may be required by the Securities Act); (e) upon request, furnish each Holder of Registrable Securities a signed counterpart, addressed to such Holder, of an opinion of counsel for the Company, dated the effective date of such registration statement (or, if such registration statement includes an underwritten public offering, dated the date of closing under the underwriting agreement), with opinions of issuer's counsel with respect to corporate and securities and patent issues as customarily delivered in connection with public offerings; (f) promptly notify each Holder of Registrable Securities covered by such registration statement and each underwriter thereof, if any, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, upon the Company's discovery that, or upon the happening of any event of which the Company has knowledge as a result of which, the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing, and at the request of any such Holder or underwriter promptly prepare and furnish to such Holder or underwriter, if any, a reasonable number of copies of a prospectus supplemented or amended so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; (g) otherwise use diligent efforts to comply with all applicable rules and regulations of the Commission, and make generally available (within the meaning of Section 11(a) of the Securities Act and the regulations thereunder) to its securityholders, as soon as reasonably practicable, an earnings statement covering a period of at least twelve months, beginning with the first month of the first fiscal quarter after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and the regulations thereunder; (h) provide and cause to be maintained a transfer agent and registrar for all Registrable Securities covered by such registration statement from and after a date not later than the effective date of such registration statement; (i) use diligent efforts to list all Company Common Stock covered by such registration statement on each securities exchange on which any of the Company Common Stock is then listed or, if the Company Common Stock is not then listed on any national securities exchange but is included in Nasdaq or the Nasdaq National Market, use diligent efforts to have such Company Common Stock included in Nasdaq or the Nasdaq National Market, as the case may be; and (j) in connection with each such registration, give the Holders of Registrable Securities to be registered therein, their underwriters, if any, and up to one designated -8- counsel and one designated accounting firm to represent the interests of such Holders, at the expense of such Holders, the reasonable opportunity to participate in the preparation prior to filing of the related registration statement, each prospectus included therein or filed with the Commission, and each amendment thereof or supplement thereto; (k) upon receipt by the Company of reasonable confidentiality agreements, make available for inspection by any underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other agent retained by any such underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company's officers, directors, employees and independent accountants to be available on a reasonable basis and cooperate with such parties' "due diligence" and to supply all information reasonably requested by any such underwriter, attorney, accountant or agent in connection with such registration statement, provided that the Company may refrain from disclosing any proprietary or other information that is not material to the Company's financial condition or results of operations; and (l) in the event of the issuance of any stop order suspending the effectiveness of a registration statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Company Common Stock included in such registration statement for sale in any jurisdiction, the Company will use diligent efforts promptly to obtain the withdrawal of such order. The Holders agree that, upon receipt of any notice from the Company of the occurrence of any event of the kind described in Section 6(f) hereof, the Holders will forthwith discontinue their disposition of Registrable Securities pursuant to the registration statement relating to such Registrable Securities until the Holders' receipt of the copies of the supplemented or amended prospectus contemplated by Section 6(f) hereof and, if so directed by the Company, will deliver to the Company (at the Company's expense) all copies, other than permanent file copies, then in the Holders' possession of the prospectus relating to such Registrable Securities current at the time of receipt of such notice. In the event the Company shall give any such notice, the three-year and 180-day periods referred to in Sections 5 and 6(a) hereof, respectively, shall be extended by the length of the period from and including the date when each Holder of any Registrable Securities covered by such registration statement shall have received such notice to the date on which each such Holder has received the copies of the supplemented or amended prospectus contemplated by Section 6(f) hereof. In connection with each such registration, each Holder of Registrable Securities to be named in the registration statement shall furnish to the Company such information regarding such Holder and the proposed distribution of such Registrable Securities as the Company may from time to time reasonably request in writing, and the delivery of such information shall be a condition precedent to the obligation of the Company to file any registration statement. 7. Underwritten Offerings. -9- (a) Underwritten Offerings Requested by Holders. If requested by the underwriters for any underwritten offering by a Holder or Holders pursuant to a registration requested under Section 3 hereof, the Company will enter into an underwriting agreement with such underwriters for such offering, such agreement to be reasonably satisfactory in substance and form to the Company, such Holder or Holders and the underwriters, and to contain such representations and warranties by the Company for the benefit of the underwriters and the Holders and such other terms as are customarily contained in an underwriting agreement with respect to such an offering, including, without limitation, representations and warranties by the Company to the underwriters, provisions regarding the delivery of opinions of counsel, a "cold comfort" letter and updates thereof and other closing certificates and documents, in each case as customarily included in underwritten public offerings, and indemnities substantially to the effect and to the extent provided in Section 9 hereof. Such Holder or Holders will cooperate with the Company in the negotiation of the underwriting agreement and will give consideration to the reasonable suggestions of the Company regarding the form thereof; provided, however, that nothing herein contained shall diminish the foregoing obligations of the Company. Such Holder or Holders of Registrable Securities to be distributed by such underwriters shall be parties to such underwriting agreement, which may contain representations and warranties of the Holders for the benefit of the underwriters and the Company as are usual and customary and may require that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of such Holder or Holders. (b) Underwritten Piggy-Back Offerings. The Holder or Holders of Registrable Securities to be distributed by an underwritten offering described in Section 4 hereof shall be parties to the underwriting agreement between the Company and such underwriters and may require that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of such Holder or Holders. No such Holder shall be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Holder, such Holder's Registrable Securities and such Holder's intended method of distribution customarily given to underwriters and any other representation required by law. 8. Expenses. All expenses incurred by the Company in complying with Sections 3, 4, 6 and 7 hereof, including, without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel and independent public accountants for the Company, reasonable fees and expenses of one counsel for the holders of Registrable Securities participating in such registration (not to exceed $25,000 for all registrations pursuant to Section 3(a)(i) hereof, each registration pursuant to Section 4 hereof, and each registration pursuant to Sections 3(a)(ii) and 3(b) hereof), fees and expenses incurred in connection with complying with state securities or "blue sky" laws, fees of the National Association of Securities Dealers, Inc., fees of transfer agents and registrars, and costs of insurance, but excluding any Selling Expenses, are herein called -10- "Registration Expenses."

The Company will pay all Registration Expenses in connection with any registration pursuant to this Agreement. All Selling Expenses in connection with each such registration shall be borne by the participating Holders in proportion to the number of shares of Registrable Securities sold by each, or as such Holders may otherwise agree. 9. Indemnification. (a) Indemnification by the Company. In the event of any registration, qualification or compliance effected pursuant to Sections 3 or 4 hereof, the Company shall indemnify and hold harmless the Holder of any Registrable Securities covered by such registration statement, its directors and officers and affiliates, if any, each underwriter of such Registrable Securities thereunder, if any, each broker, dealer, or similar person acting on behalf of any such Holder, and each other person, if any, who controls any of the foregoing persons within the meaning of the Securities Act (each a "Company Indemnitee" and collectively the "Company Indemnitees"), in each case, against any losses, claims, damages or liabilities, joint or several, to which such Company Indemnitee may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any breach of any representation, warranty, agreement or covenant of the Company contained in the underwriting agreement covering the public offering of such Registrable Securities or untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Registrable Securities were registered under the Securities Act pursuant to Sections 3 or 4, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, or any other document incident to any such registration, qualification or compliance, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance, and the Company will reimburse such Company Indemnitee for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided, however, that the Company shall not be liable in any such case if and to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such document in reliance upon and in conformity with written information furnished to the Company by such Company Indemnitee, specifically for use in such document; and provided further, that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement or alleged untrue statement or omission or alleged omission made in the preliminary prospectus but eliminated or remedied in the amended -11- prospectus on file with the Commission at the time the registration statement becomes effective or in the amended prospectus filed with the Commission pursuant to Rule 424(b) or in the prospectus subject to completion and term sheet under Rule 434 of the Securities Act, which together meet the requirements of Section 10(a) of the Securities Act (the "Final Prospectus"), such indemnity agreement shall not inure to the benefit of any such seller, any such underwriter or any such controlling person, if a copy of the Final Prospectus was not furnished to the person or entity asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act, but only if the Company had previously furnished a sufficient number of copies of the Final Prospectus to such seller for distribution to any underwriter or controlling person. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Holder, director, officer, underwriter or controlling person, shall survive the transfer of such securities by any Holder or underwriter, and shall be in addition to any liability which the Company may otherwise have. (b) Indemnification by the Holders. In the event of any registration, qualification or compliance effected pursuant to Sections 3 or 4 hereof, each Holder selling Registrable Securities pursuant thereto shall indemnify and hold harmless the Company, each director of the Company, each officer of the Company and each other person, if any, who controls the Company within the meaning of the Securities Act, each underwriter, if any, and each person who controls any of the foregoing persons within the meaning of the Securities Act (each a "Holder Indemnitee" and collectively the "Holder Indemnitees"), in each case, against any losses, claims, damages or liabilities, joint or several, to which a Holder Indemnitee may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) any breach of any representation, warranty, agreement or covenant of such Holder contained in the underwriting agreement covering the public offering of such Registrable Securities or (ii) any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Registrable Securities were registered under the Securities Act pursuant to Sections 3 or 4, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, or any other document incident to any such registration, qualification or compliance, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Holder Indemnitee for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, but only to the extent that any such loss, claim, damage or liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information pertaining to such Holder, as such, furnished in writing to the Company by such Holder specifically for use in such document; provided, however, that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement or alleged untrue statement or omission or alleged omission made in the preliminary prospectus but eliminated or remedied in the amended prospectus on file with the Commission at the -12- time the registration statement becomes effective or in the Final Prospectus, such indemnity agreement shall not inure to the benefit of the Company, any controlling person or any underwriter, if the Company had an obligation under the Securities Act to deliver the Final Prospectus to the person or entity asserting the loss, liability, claim or damage and such Final Prospectus was not so furnished at or prior to the time such furnishing is required by the Securities Act; and provided, further, that, in the case of a registration pursuant to Section 3 or 4 hereof, in no event shall any indemnity by a seller under this Section 9(b) exceed the gross proceeds from the offering received by such seller. Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer, underwriter or controlling person, shall survive the transfer of such Registrable Securities by any such Holder or underwriter, and shall be in addition to any liability which any such Holder may otherwise have. (c) Notices of Claims, etc. Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in the preceding provisions of this Section 9, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action; provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under the preceding provisions of this Section 9, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action or proceeding is brought against an indemnified party, unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, the indemnifying party shall be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified, to the extent that the indemnifying party may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 9 for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the consent of the indemnified party, consent to entry of any judgment or enter into any settlement of any such action which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability, or a covenant not to sue, with respect to such claim or litigation. No indemnified party shall consent to entry of any judgment or enter into any settlement of any such action the defense of which has been assumed by an indemnifying party without the consent of such indemnifying party (which consent shall not be unreasonably withheld). (d) Indemnification Payments. The indemnification required by this Section 9 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred. -13- (e) Contribution. If for any reason the indemnification provided for in the preceding provisions of this Section 9 is unavailable to an indemnified party in respect of any losses, claims, damages or liabilities (or any action or proceeding in respect thereof) referred to therein, then each indemnifying party, in lieu of indemnifying an indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or any action or proceeding in respect thereof) (i) as between the Company and the Holders on the one hand and the underwriters on the other, in such proportion as is appropriate to reflect the relative benefits received by the Company and the Holders on the one hand and the underwriters on the other from the offering of the securities, or if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits but also the relative fault of the Company and the Holders on the one hand and of the underwriters on the other in connection with the statement or omissions which resulted in such losses, claims, damages or liabilities (or action or proceeding), as well as any other relevant equitable considerations and (ii) as between the Company on the one hand and each Holder on the other, in such proportion as is appropriate to reflect the relative fault of the Company and of each Holder in connection with such statements or omissions, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Holders on the one hand and the underwriters on the other shall be deemed to be in the same proportion as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company and the Holders bear to the total underwriting discounts and commissions received by the underwriters, in each case as set forth in the table on the cover page of the prospectus. The relative fault of the Company and the Holders on the one hand and of the underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Holders or by the underwriters. The relative fault of the Company on the one hand and of each Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Each Holder's obligation to contribute pursuant to this Section 9 is several, and not joint, in the proportion that the proceeds of the offering -14- received by such Holder bears to the total proceeds of the offering received by all the Holders. 10. Rule 144. With a view to making available the benefits of certain rules and regulations of the Commission which may permit the sale of the Registrable Securities to the public without registration, the Company agrees to: (a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act; (b) use diligent efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; (c) furnish to a Holder of Registrable Securities forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act a copy of the most recent annual or quarterly report of the Company, and such other reports and documents previously filed as the Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing the Holder to sell any such securities without registration; and (d) in accordance with the Company's current practices, pay the fees and expenses of the Company's counsel in obtaining routine, appropriate opinions of counsel (to the effect that registration under Securities Act will or will not be required for any sale or transfer) if at any time or from time to time any holder desires to sell or otherwise transfer any or all of the Registrable Securities held by it pursuant to Rule 144 or Rule 145(d) under the Securities Act. 11. Lock-Up. (a) Company Lock-Up. The Company agrees not to effect any public sale or public distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during the 30-day period prior to and during the 90-day period beginning on the commencement date of any underwritten offering on behalf of the Holders (except pursuant to (i) registrations on Form S-8 or any successor form, (ii) registrations on Form S-4 or any successor form and (iii) as part of such underwritten registration, if permitted pursuant to Section 3(d)), unless the underwriters managing such offering otherwise agree; provided, however, that the foregoing 30-day and 90-day periods shall be extended to the extent requested by such managing underwriters, but not beyond a 60-day and 180-day period, respectively. (b) Holder Lock-Up. Each Holder agrees not to effect any public sale or other distribution of Company Common Stock, or any securities convertible into or exchangeable or exercisable therefor, during the 30-day period prior to (or if less, the period beginning on the date notice of such proposed offering is received) and during the -15- 90-day period beginning on the commencement of any underwritten offering on the part of the Company of Company Common Stock being sold for the account of the Company (except pursuant to (i) registrations on Form S-8 or any successor form, (ii) registrations on Form S-4 or any successor form and (iii) any part of such underwritten registration, if permitted pursuant to Section 4(a)), unless the underwriters managing such offering otherwise agree; provided, however, that the foregoing 30-day and 90-day periods shall be extended to the extent requested by such managing underwriters, but not beyond a 60-day and 180-day period, respectively. 12. Amendments and Waivers. This Agreement may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, if the Company shall have obtained the written consent to such amendment, action or omission to act, of the holders of at least seventy percent (70%) of the Registrable Securities initially issued pursuant to the Merger Agreement. 13. Notices. All notices, consents, waivers, and other communications under this Agreement must be in writing and will be deemed to have been duly given when (a) delivered by hand (with written confirmation of receipt), (b) sent by facsimile (if received during regular business hours; otherwise on the next business day) (with written confirmation of receipt), provided that a copy is mailed by registered mail, return receipt requested, or (c) when received by the addressee, if sent by certified mail or a nationally recognized overnight delivery service (receipt requested), in each case to the appropriate addresses and facsimile numbers set forth below (or to such other addresses and facsimile numbers as a party may designate by notice to the other parties): (a) If to the Company: ATMI, Inc. 7 Commerce Drive Danbury, Connecticut 06810-4169 Attention: President and CEO Facsimile: (203) 792-8040 with a copy to: Frank J.

(b) The parties hereto agree that the Shareholders shall be treated as the owners of the shares of Buyer Common Stock comprising the Escrow Fund, excluding any funds disbursed pursuant to the provisions hereof or the Merger Agreement, and shall file all of their respective returns, reports and similar information in a manner consistent with such ownership. The Representative, on behalf of the Shareholders, shall be responsible for any tax liability and tax reporting obligations attributable to the placement of the Indemnification Escrow Shares in the Escrow Fund and the payment of any interest or other amounts payable with respect to the Escrow Fund. The Representative, on behalf of the Shareholders, agrees to provide the Escrow Agent with executed Forms W-9 or W-8, as applicable. 3. Representative of the Shareholders. From and after the establishment of the Indemnification Escrow, as provided in Section 2 hereof, the Shareholders shall be represented hereunder by the Representative. In the event that the Representative shall die or resign or otherwise terminate his status as such, his successor shall be selected by the vote or written consent of not less than a majority in interest of the Shareholders. The Representative is authorized to act on behalf of the Shareholders as provided in this Agreement and the Merger Agreement without further authority from the Shareholders. The Representative shall not be entitled to be compensated for acting as Representative hereunder. Notwithstanding anything herein to the contrary, the appointment or selection of or granting of authority to the Representative shall not impair the right of any Shareholder to exercise such Shareholder's right to vote any share of Buyer Common Stock (or Holdings' Common Stock, if the closing of the transactions contemplated by the ADCS Merger shall occur on or before the Effective Time of the Merger) owned by such Shareholder. 4. Investment of Escrow Funds. The Escrow Agent shall, except to the extent that amounts in the Indemnification Escrow are required to satisfy a claim for payment, invest all cash dividends included in the Escrow Fund in Authorized Investments. "Authorized Investments" shall mean (a) direct obligations of the United States of America (including certificates or other instruments evidencing ownership interests in such obligations) or obligations the timely payment of the principal and interest on which are fully guaranteed by the United States of America or any daily or weekly withdrawal money market fund investing solely in such obligations or interest bearing demand or time deposits and banker's acceptance in any bank (including the Escrow Agent and its affiliates) which is rated one of the two highest rating categories by Moody's or Standard & Poors. The Escrow Agent shall hold all monies collected on account of interest earnings in the Indemnification Escrow and such earnings shall become part of the Escrow Fund. 5. Claims Against the Escrow Fund. (a) If and whenever Buyer, acting on its behalf or on behalf of the Company or any other Indemnitee, shall claim indemnification or other payment in respect of a liquidated claim to be satisfied out of the Indemnification Escrow pursuant to the Merger Agreement, Buyer shall promptly send written notice of the same to the Escrow Agent and the Representative (or his successor, as provided above). Such notice shall state the basis for such claim including a brief description of the facts upon which such claim is based and the amount thereof. In the event of an unliquidated claim pursuant to the Merger Agreement, Buyer shall provide written notice to the Representative and the Escrow Agent of the unliquidated claim, including a brief description of the facts upon which such claim is based and a demand for a reserve amount to be created in respect of such claim. Any claim that is unliquidated shall not be paid, but the Escrow Agent shall set aside Buyer Common Stock valued at the Average Closing Price equal to such claim within the Escrow Fund to address such claim until such claim is fully liquidated. If the Representative shall object to any such claim, he shall send written notice of his objection to the Escrow Agent within thirty (30) days after Buyer's delivery of its notice as aforesaid. If no objection to such claim shall have been received by the Escrow Agent within thirty (30) days after delivery to it of Buyer's notice, the Representative, on behalf of the Shareholders, shall be deemed to have acknowledged the correctness of such claim for the full amount thereof and the Escrow Agent shall transfer to Buyer as provided in the following sentence on behalf of the claiming party out of the Indemnification Escrow an amount (pro rata from the account of each Shareholder) equal to the amount of such claim. Transfer to Buyer of the funds shall be made, in the case of a liquidated claim, promptly following such thirty-day period, or, in the case of an unliquidated claim, promptly following the date upon which the claim is fully liquidated. For the purpose of this paragraph (a), the term "delivery" shall mean, in the case of notices sent by mail, the time at which such notice is mailed, in the case of notices delivered personally, the time at which such notice is delivered and, in the case of notices sent by telecopy, the time at which such notice is sent. Adjustments pursuant to Section 3.5 of the Merger Agreement shall be determined, and paid in accordance with the procedures set forth in the Merger Agreement. (b) Notwithstanding the foregoing, no amount will be paid pursuant to a written claim notice for indemnification pursuant to Article X of the Merger Agreement (with respect to either a liquidated or unliquidated claim) unless, and then only to the extent that, the aggregate amount of Losses sustained by Indemnitees as a group and as to which written claim notices have been given by Buyer to the Escrow Agent exceeds Two Hundred Fifty Thousand Dollars ($250,000) (taking into account any reduction of prior noticed claims resulting from the dispute resolution procedures of paragraph (c) below). (c) If the Representative shall timely notify the Escrow Agent in writing of his good faith objection to a claim of indemnification or other payment or a demand for the creation of reserve for any unliquidated claim (or the amount thereof), the Escrow Agent shall hold the disputed amount of funds in the Indemnification Escrow until the rights of the Shareholders and the claiming party or parties with respect thereto have been agreed upon between the Representative and the claiming party or parties. In the event such an agreement is reached, the claiming party or parties shall request Buyer to provide to the Escrow Agent a written notice signed by the Representative acknowledging that such agreement has been reached and authorizing the Escrow Agent to release funds having a value equal to the agreed amount specified in the notice in the same manner set forth for undisputed claims as provided in paragraph (a) hereof. If no such agreement has been reached, either the claiming party or parties or the Representative may, not earlier than thirty (30) days after the date of the initial claim notice, submit the dispute to confidential, binding arbitration in New York, New York, before a panel of three (3) arbitrators, one (1) each to be selected by the Buyer and the Representative, and the third to be selected by the other two (2) arbitrators pursuant to the procedures and rules for commercial arbitration of the American Arbitration Association. The Escrow Agent may rely on the order or other determination of any such arbitrators. If such arbitrators shall determine that any part of the Indemnification Escrow is to be delivered to a claiming party or parties or is to be set aside in a reserve for any unliquidated claim, the Escrow Agent shall promptly following receipt of a copy of such determination establish such reserve or deliver to such claiming party or parties the lesser of (i) the amount of the claim or claims as awarded to be satisfied, subject to the limitation set forth in paragraph (a) above, or (ii) the entire amount remaining in the Indemnification Escrow. Any disputed amounts not awarded shall promptly be transferred to the unreserved portion of the Indemnification Escrow. Buyer and the Representative shall bear their respective costs and expenses of any such arbitration. (d) On and after the Termination Date, the Escrow Agent shall distribute to the Shareholders on a pro rata basis all remaining unreserved amounts in the Indemnification Escrow less an amount equal to the dollar amount of all claims (i) that are then-payable liquidated claims, (ii) for which a reserve established pursuant to paragraph (a) above then exists, or (iii) that are still in process of resolution pursuant to paragraph (c) hereof. No new claims for indemnification under Section 10.1 of the Merger Agreement may be brought after the Termination Date. Notwithstanding the foregoing or anything in this Agreement to the contrary, no claim seeking indemnification from the Shareholders or the Indemnification Escrow may be brought after the date of issuance of the first independent audit report with respect to the financial statements of the Buyer (or Holdings, if the closing of the transactions contemplated by the ADCS Merger Agreement shall occur on or before the Effective Time) after the Effective Time if such claim is of a type expected to be encountered in the course of an audit performed in accordance with generally accepted auditing standards. (e) After the Termination Date, (i) as each matter referred to in paragraph (d) hereof is resolved or otherwise concluded and (ii) as each undisputed liquidated claim under paragraph (a) which remains unliquidated as of the Termination Date is liquidated, the Escrow Agent shall distribute to the Shareholders their respective pro rata portion of the Escrow Fund then determined by the Escrow Agent to be free of any rights of any Indemnitee. (f) To the extent that the Indemnitees make a claim against the Escrow Fund pursuant to this Agreement, and such claim is paid in shares of Buyer Common Stock, then for purposes of such payment, the shares of Buyer Common Stock (or Holdings' Common Stock, if the closing of the transactions contemplated by the ADCS Merger shall occur on or before the Effective Time of the Merger) shall be valued at the Average Closing Price. 6. Termination of Escrow. (a) The Indemnification Escrow provided for hereunder shall terminate upon written notification by Buyer to the Escrow Agent that the Shareholders' indemnity obligation under Article X of the Merger Agreement has been satisfied or waived by Buyer. Such written notification shall be provided by Buyer to the Escrow Agent as soon as practicable after the date which is one year after closing. (b) Upon such notice, the Escrow Agent shall pay over the Escrow Fund, if any, to the Shareholders as their respective interests may appear. 7. Escrow Agent. (a) The Escrow Agent shall be entitled to receive compensation for its services as Escrow Agent. Such compensation shall be paid by Buyer. (b) The Escrow Agent's duties and responsibilities shall be limited to those expressly set forth in this Escrow Agreement and in the Merger Agreement, and it shall not be subject to, or obliged to recognize, any other agreement between the parties hereto even though reference thereto may be made herein; provided, however, that with the Escrow Agent's written consent, this Escrow Agreement may be amended at any time or times by an instrument in writing signed by or on behalf of Buyer, the Company (or after the merger, Surviving Corporation), the Representative and the Escrow Agent. The Escrow Agent may withhold such consent only if such amendment would adversely affect the rights or liabilities of the Escrow Agent. (c) The Escrow Agent is authorized, in its reasonable discretion, to disregard any and all notices or instructions given by any of the parties hereto or by any other person, firm or corporation, except only (i) such notices or instructions as are herein or in the Merger Agreement specifically provided for, and (ii) orders or process of any court with jurisdiction. If any property in the Indemnification Escrow is at any time attached, garnished or levied upon or under any court order or in case the payment, assignment, transfer, conveyance or delivery of any such property shall be stayed or enjoined by any court order, or in case any order, judgment or decree shall be made or entered by any court affecting such property or any part thereof, then, and in any of such events the Escrow Agent is authorized, in its sole discretion, to rely upon and comply with any such order, writ, judgment or decree which it is advised by legal counsel of its own choosing is binding upon it; and if it complies with any such order, writ, judgment or decree it shall not be liable to any of the parties hereto or to any other person, firm or corporation by reason of such compliance even though such order, writ, judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated. (d) The Escrow Agent shall not be personally liable for any act taken or omitted hereunder if taken or omitted by it in good faith. In taking any action whatsoever hereunder, the Escrow Agent shall be protected in relying upon any notice, paper or other document reasonably believed by it to be genuine, or upon any evidence reasonably deemed by it to be sufficient. The Escrow Agent may consult with counsel in connection with its duties hereunder and shall be fully protected in any act taken, suffered or permitted by it in good faith in accordance with the advice of counsel. It shall also be fully protected in relying upon any written notice, demand, certificate or document which it in good faith believes to be genuine. The Escrow Agent shall not be responsible for the sufficiency or accuracy of the form, execution, validity or genuineness of documents now or hereafter deposited hereunder, nor shall it be responsible or liable in any respect on account of the identity, authority or rights of the persons executing and delivering or purporting to execute or deliver any such document. (e) If the Escrow Agent believes it to be reasonably necessary to consult with counsel concerning any of its duties in connection with this Escrow Agreement, or in case it becomes involved in litigation on account of being Escrow Agent hereunder or on account of having received property subject hereto, then in either case, the Escrow Agent's costs, expenses, and reasonable attorneys' fees shall be paid by Buyer. (f) Buyer and Shareholders hereby indemnify and hold harmless the Escrow Agent from and against any and all Losses which the Escrow Agent may suffer or incur by reason of any action, claim or proceeding brought against the Escrow Agent arising out of or relating in any way to this Agreement or any transaction to which this Agreement relates unless such action, claim or proceeding is the result of the gross negligence or willful misconduct of the Escrow Agent, provided, however, that one-half of Buyer's obligation hereunder shall be satisfied out of the Indemnification Escrow to the extent thereof. (g) By its execution and delivery of this Escrow Agreement, the Escrow Agent acknowledges that its terms and provisions are acceptable and it agrees to carry out the provisions hereof and in the Merger Agreement on its part to be performed. 8. Resignation, Removal of Escrow Agent. The Escrow Agent may at any time resign by giving sixty (60) days' written notice of resignation to the Representative and Buyer. The Representative and Buyer may jointly at any time remove the Escrow Agent by giving written notice to the Escrow Agent. If the Escrow Agent shall resign or be removed, a successor Escrow Agent, which shall be a bank, trust company or other financial institution satisfactory to both Buyer and the Representative, shall be appointed by written instrument executed and delivered by both Buyer and the Representative to the Escrow Agent and to such successor Escrow Agent and, upon the resignation or removal of the predecessor Escrow Agent, the successor Escrow Agent shall, without any further act, deed or conveyance, become vested with all the right, title and interest to all property held hereunder, of such predecessor Escrow Agent; but nevertheless such predecessor Escrow Agent shall, on the written request of the Representative, Buyer or such successor Escrow Agent execute and deliver to such successor Escrow Agent an instrument transferring to such successor Escrow Agent all right, title and interest hereunder in and to the property in the Indemnification Escrow and all other rights hereunder, of such predecessor Escrow Agent. If no successor Escrow Agent has been appointed at the end of sixty (60) days after notice of resignation by the Escrow Agent, the Escrow Agent hereunder may seek relief from a court of competent jurisdiction, in interpleader proceedings in which Buyer and the Representative shall be joined as parties. 9. Governing Agreement; Amendments. The Escrow Agent hereby acknowledges receipt of a copy of the Merger Agreement. As between the Escrow Agent, on the one hand, and the other parties hereto, on the other hand, this Escrow Agreement together with the applicable provisions of the Merger Agreement constitutes the entire agreement with respect to the subject matter herein. Representative, and Buyer and the Company agree to make such amendments herein as may be necessary to reconcile any conflict between the terms hereof and the Merger Agreement. No change in, addition to, or waiver of the terms and conditions hereof shall be binding upon any of the parties hereto unless approved in writing by the other parties hereto. 10. Notices.

WHEREAS, the Company has entered into that certain Agreement and Plan of Merger (the "Merger Agreement") dated May 17, 1997 as amended by a First Amendment thereto dated June 6, 1997 and a Second Amendment thereto dated July 30, 1997 among the Company, LAWRENCE SEMICONDUCTOR LABORATORIES MARKETING AND SALES, INC., an Arizona corporation; ADVANCED TECHNOLOGY MATERIALS, INC., a Delaware corporation; ATMI, INC. (f/k/a ATMI HOLDINGS, INC.), a Delaware corporation; and WELK ACQUISITION CORPORATION, a Delaware corporation ("Buyer Sub"), whereby the Company will be acquired by the Buyer by the Merger of the Buyer Sub with and into the Company upon the terms set forth therein; and WHEREAS, the Merger Agreement calls for the Company to enter into a Consulting Agreement with Lamonte H. Lawrence ("Lawrence"); and WHEREAS, Consultant has an exclusive arrangement with Lawrence regarding his consulting services; and WHEREAS, the Company and Consultant desire to enter into a consulting arrangement on the terms set forth below. All capitalized terms not otherwise defined in this Agreement shall have the meaning ascribed to each such term in the Merger Agreement. NOW, THEREFORE, the Company and Consultant agree as follows: 1. Termination of Employment Relationship. As of the Effective Date, Consultant and the Company hereby agree that the employment of Lawrence by LSL shall terminate and LSL's obligations under any employment agreement shall cease at such time. 2.

The Company hereby retains Consultant as an independent consultant for the three (3) year period ("Consulting Term") from the Effective Time (the "Expiration Date"), or such earlier date on which this Agreement is terminated as provided in Section 7, below. Consultant shall retain the services of Lawrence to provide consulting services hereunder to the Company throughout the term of this Agreement, unless the Company shall provide its prior written consent given in its sole discretion, to Consultant regarding the retention of the services of another expert in epitaxial processing of silicon wafers to provide consulting services to the Company. 3. Consulting Services. Consultant shall perform those consulting services and work on such projects as Consultant and the Company may from time to time mutually agree. Consultant's relationship with the Company shall be that of an independent contractor and not that of an employee of the Company or any affiliate and, except as otherwise provided herein, Consultant shall not be eligible for any employee benefits offered by the Company, and the Company shall neither make nor be liable for any deductions from Consultant's fees paid hereunder for taxes, insurance, bonds or any other subscriptions of any kind.

Termination. This Agreement shall be subject to termination as follows: (a) Consultant may terminate this Agreement at any time after one (1) year from the Effective Time upon thirty (30) days' written notice to the Company; (b) The Company may terminate this Agreement only for "cause" which, for purposes of this Agreement, shall mean (i) the continued failure by Consultant or Lawrence to perform his duties with the Company (other than any such failure resulting from his incapacity due to death or physical or mental incapacity), after a written demand for substantial performance is delivered to Consultant or Lawrence by the Company that identifies the manner in which the Company believes that Consultant or Lawrence has not substantially performed his duties and provides for a 30-day cure period, (ii) engaging by Consultant or Lawrence in misconduct which is materially injurious to the Company, monetarily or otherwise, after a written warning and a 30-day cure period, (iii) Consultant's or Lawrence's final conviction for fraud or of any felony, or (iv) Consultant's or Lawrence's use of illegal drugs and/or abuse of alcohol. Notwithstanding the foregoing, Consultant shall not be deemed to have been terminated for cause under clause (i) or (ii) unless and until there shall have been delivered to Consultant a copy of a Notice of Termination from the Board of Directors of the Company after reasonable notice to Consultant and an opportunity for Consultant to be heard before the Board finding that, in the good faith opinion of the Board, Consultant was guilty of conduct set forth above and specifying the particulars thereof in detail. (c) This Agreement, and the Company's obligations hereunder, shall terminate immediately upon Consultant's or Lawrence's disability. For purposes of this Agreement, the term "disability" shall be defined as a physical or mental impairment of any type that prevents Consultant or Lawrence from performing the essential functions of his employment under this Agreement for a total period of ninety (90) days in any twelve (12) consecutive month period, as reasonably determined by the Company. (d) This Agreement shall terminate upon the death of Consultant or Lawrence. 8. Effect of Termination. Upon termination of this Agreement pursuant to Section 7 hereof, Sections 8, 9, and 10 shall survive, and Consultant shall be entitled to receive all fees and expenses payable under Section 5 through the date of termination of this Agreement. 9. Indemnification.

Additional Instruments. The parties hereto shall execute any further or additional instruments and they will perform any acts which may be reasonably necessary or appropriate in order to effectuate and carry out the purposes of this Agreement. 11. Execution in Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which shall constitute one and the same agreement. 12.

Binding Agreement. This Agreement shall inure to the benefit of and shall be binding upon the Company and Consultant, and their respective successors and assigns. 16. Severability. 16.1 Severable.

To the extent that any provision hereof is deemed unenforceable by virtue of its scope in terms of area, business activity prohibited and/or length of time, but could be enforceable by reducing the scope of area, business activity prohibited or length of time, Consultant and the Company agree that same shall be enforced to the fullest extent permissible under the laws and public policies applied in the jurisdiction in which enforcement is sought, and that the Company shall have the right, in its sole discretion, to modify such invalid or unenforceable written provision to the extent required to be valid and enforceable. Consultant agrees to be bound by any promise or covenant imposing the maximum duty permitted by law which is subsumed within the terms of any provision hereof, as though it were separately articulated in and made a part of this Agreement, that may result from striking or modifying any of the provisions hereof. IN WITNESS WHEREOF, the parties have executed this Agreement the date first written above. CONSULTANT: LAWRENCE SEMICONDUCTOR INVESTMENTS, INC., an Arizona corporation By /s/ LAMONTE H. LAWRENCE Lamonte H. Lawrence, President THE COMPANY: LAWRENCE SEMICONDUCTOR LABORATORIES, INC., an Arizona corporation By /s/ LAMONTE H. LAWRENCE Its President, CEO EX-99.(F) 7 EXHIBIT 99(F) Exhibit (f) NONCOMPETE AGREEMENT This NONCOMPETE AGREEMENT (the "Agreement") is made as of this 10th day of October, 1997, by and among ADVANCED TECHNOLOGY MATERIALS, INC., a Delaware corporation ("Buyer"), WELK ACQUISITION CORPORATION, a Delaware corporation and a wholly-owned subsidiary of Buyer ("Buyer Sub"), LAWRENCE SEMICONDUCTOR LABORATORIES, INC., an Arizona corporation (the "Company"), and LAMONTE H. LAWRENCE, an individual ("Shareholder"). WHEREAS, Shareholder is a shareholder, officer and director of the Company; WHEREAS, Buyer is acquiring the Company through the merger of Buyer Sub into the Company (the "Merger"), as provided in the Agreement and Plan of Merger dated May 17, 1997 as amended by a First Amendment thereto dated June 6, 1997 and a Second Amendment thereto dated July 30, 1997, among Buyer, Buyer Sub, ATMI, Inc. (f/k/a ATMI Holdings, Inc.), and the Company (the "Merger Agreement"); WHEREAS, Shareholder has voted all of his shares of Company stock owned by Shareholder in favor of the Merger; WHEREAS, Company is in the business (the "LSL Business") of the chemical vapor deposition of silicon wafers using epitaxial processes to meet product specifications furnished by the Company's customers for certain applications, as conducted on the date of this Agreement and during the term of that certain Consulting Agreement of even date herewith between the Company and Lawrence Investments, Inc., an Arizona corporation wholly owned by Shareholder (the "Consulting Agreement"); WHEREAS, Shareholder is knowledgeable of, and has well-established goodwill in and relationships and contacts with, the LSL Business; WHEREAS, Buyer expects to receive, as a result of the Merger, all of the assets, goodwill, trademarks, service marks, trade names and fictitious business names of Company; WHEREAS, Buyer has required that Shareholder enter into this Agreement as a condition to Buyer and the Buyer Sub consummating the Merger. NOW, THEREFORE, in order to induce Buyer and Buyer Sub to consummate the Merger, Shareholder hereby agrees as follows: 1. Non-competition. a. Except as provided in the following sentence, Shareholder agrees that, for a period of the later of five (5) years from the date of this Agreement and three (3) years from the expiration of the Consulting Agreement, Shareholder will not, directly or indirectly, engage or participate in, prepare or set up, assist or have any interest in any person, partnership, corporation, firm, association, or other business organization, entity or enterprise (each, a "Person") (whether as an employee, officer, director, partner, owner, consultant or otherwise) that engage in any activities in competition with the LSL Business. Nothing herein shall preclude Lawrence Semiconductor Research Laboratories, Inc. ("LSRL"), of which Shareholder is the sole owner, from engaging in research and development, or the chemical vapor deposition of silicon wafers using epitaxial processes; provided, however, that the processing of wafers for LSRL's customers shall not exceed 1000 wafers per specification without the prior written consent of the Company, which consent shall not be unreasonably withheld. b. Nothing in this Section shall be deemed to prohibit Shareholder from pur chasing or owning equity securities of any issuer if those securities constitute less than five percent (5%) of the class of equity securities and that class is registered under the Securities Exchange Act of 1934. 2. Shareholder's Additional Covenants. Shareholder shall not, for a period of five (5) years from the date of this Agreement, directly or indirectly, hire, or induce or encourage any employee or consultant or group of employees or consultants who are then employed or retained by Buyer or the Company, to leave the employment of or terminate consultation with Buyer or the Company or any of their subsidiaries, without the prior written consent of Buyer. 3. Consideration. Shareholder understands and acknowledges that the provisions of this Agreement are necessary to protect the legitimate business interests of Buyer, Buyer Sub and the Company and are fair and reasonable for numerous reasons, including Shareholder's receipt of shares of Buyer common stock in connection with the Merger and the consideration provided in the Consulting Agreement.
