Exhibit 99.1 AGREEMENT AND PLAN OF MERGER AGREEMENT AND PLAN OF MERGER (this "AGREEMENT"), dated as of October 23, 1999, by and among Geoscience Corporation, a Nevada corporation (the "COMPANY"), Compagnie Generale de Geophysique, a French societe anonyme ("PARENT"), and Sercel Acquisition Corp., a Nevada corporation and a direct wholly owned subsidiary of Sercel Inc., an Oklahoma corporation ("SERCEL"), and an indirect wholly owned subsidiary of Parent ("PURCHASER"). RECITALS A. The Board of Directors of the Company has determined that it is in the best interests of the Company and its Stockholders for Purchaser to acquire the Company on the terms and subject to the conditions set forth herein (the "ACQUISITION"). B. As a first step in the Acquisition, the Company, Parent and Purchaser each desire that Parent cause Purchaser to commence a cash tender offer (the "OFFER") to purchase all of the Company's issued and outstanding shares (the "SHARES") of common stock, $.01 par value per share (the "COMMON STOCK"), for $6.71 per Share (the "PER SHARE AMOUNT"), on the terms and subject to the conditions set forth in this Agreement. C. To complete the Acquisition, each of the Boards of Directors (or similar governing bodies) of the Company, Parent, Sercel (on its behalf and as the sole stockholder of Purchaser) and Purchaser has approved this Agreement and the merger of Purchaser with and into the Company (the "MERGER"), wherein any issued and outstanding Shares not tendered and purchased by Purchaser pursuant to the Offer (other than Shares described in Section 2.6(b) and any Dissenting Shares) will be converted into the right to receive the Per Share Amount, on the terms and subject to the conditions of this Agreement and in accordance with the Nevada Revised Statutes (the "NRS"). D. The Board of Directors of the Company (the "COMPANY BOARD") (i) has unanimously resolved to recommend that the holders of the Shares ("STOCKHOLDERS") accept the Offer and the Merger and approve this Agreement and (ii) has determined that the consideration to be paid for each Share in the Offer and the Merger is fair to and in the best interests of the Stockholders. E. The parties desire to make certain representations, warranties and covenants in connection with the Offer and the Merger and also to prescribe various conditions to the Offer and the Merger. F. In order to induce Parent and Purchaser to enter into this Agreement, concurrently with the execution and delivery hereof, Parent, Purchaser and Tech-Sym Corporation, a Nevada corporation (the "MAJORITY STOCKHOLDER"), are entering into a Shareholder Agreement, dated as of the date hereof (the "SHAREHOLDER AGREEMENT"), pursuant to which the Majority Stockholder has agreed, among other things, to tender its Shares in accordance with the terms of the Offer and to vote its Shares in favor of the Merger and other matters necessary to consummate the transactions contemplated by this Agreement. NOW THEREFORE, in consideration of the representations, warranties and covenants contained in this Agreement, the parties agree as follows: I. THE TENDER OFFER 1.1. THE OFFER. (a) Subject to the last sentence of this Section 1.1(a), as promptly as practicable (but in any event not later than five Business Days after the public announcement of the execution and delivery of this Agreement), Parent will cause Purchaser to commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT")), the Offer whereby Purchaser will offer to purchase for cash all of the Shares at the Per Share Amount, net to the seller in cash, without interest (subject to reduction for any stock transfer taxes payable by the seller, if payment is to be made to a Person other than the Person in whose name the certificate for such Shares is registered, or any applicable federal back-up withholding), PROVIDED, HOWEVER, that Parent may designate another direct or indirect subsidiary of Parent as the bidder thereunder (within the meaning of Rule 14d-1(c) under the Exchange Act, in which case references herein to Purchaser will be deemed to apply to such subsidiary, as applicable). The obligation of Parent to cause Purchaser to consummate the Offer and to accept for payment and to pay for Shares validly tendered in the Offer and not validly withdrawn in accordance therewith 2 will be subject to, and only to, those conditions set forth in Annex A hereto (the "OFFER CONDITIONS"). (b) Without the prior written consent of the Company, Purchaser will not, and Parent will not cause Purchaser to, (i) decrease or change the form of the Per Share Amount, (ii) decrease the number of Shares sought in the Offer, (iii) amend or waive the Minimum Condition (as defined in Annex A hereto) or impose conditions other than the Offer Conditions on the Offer, or (iv) extend the expiration date of the Offer (the "EXPIRATION DATE") except (A) as required by Law, (B) that, in the event that any Offer Condition is not satisfied or waived at the time that the Expiration Date would otherwise occur, Purchaser may, in its sole discretion, without the consent of the Company, extend the Expiration Date for such period as it may determine to be appropriate (but not beyond the Outside Date), or amend any term of the Offer in any manner not materially adverse to the Stockholders, and (C) that, in the event that at least 90% of the Voting Securities, calculated on a fully diluted basis, have not been validly tendered and not withdrawn, Purchaser may, in its sole discretion, without the consent of the Company, extend the Expiration Date for an aggregate of ten additional Business Days to permit such condition to be satisfied; PROVIDED, HOWEVER, that (x) subject to applicable legal requirements, Parent may cause Purchaser to waive any Offer Condition, other than the Minimum Condition, in Parent's sole discretion and (y) the Offer may be extended in connection with an increase in the consideration to be paid pursuant to the Offer so as to comply with applicable rules and regulations of the Securities and Exchange Commission (the "SEC"). Except as set forth above and subject to applicable legal requirements, Purchaser may amend the Offer or waive any Offer Condition in its sole discretion. Assuming the prior satisfaction or waiver of the Offer Conditions, Parent will cause Purchaser to accept for payment, and pay for, in accordance with the terms of the Offer, all Shares validly tendered and not withdrawn pursuant to the Offer as soon as practicable after the Expiration Date or any extension thereof. 1.2. OFFER DOCUMENTS. (a) As soon as practicable on the date of commencement of the Offer, Parent and Purchaser will file or cause to be filed with the SEC a tender offer statement on Schedule 14D-1 ("SCHEDULE 14D-1") which will contain an offer to purchase and related letter of transmittal and other ancillary Offer documents and instruments pursuant to which the Offer will be made (collectively with any supplements or amendments thereto, the "OFFER DOCUMENTS") and which Parent and Purchaser represent, 3 warrant and covenant will comply in all material respects with the Exchange Act and other applicable Laws and will contain (or will be amended in a timely manner so as to contain) all information which is required to be included therein in accordance with the Exchange Act and the rules and regulations thereunder and other applicable Laws; PROVIDED, HOWEVER, that (i) no representation, warranty or covenant is hereby made or will be made by Parent or Purchaser with respect to information supplied by the Company in writing expressly for inclusion in, or information derived from the Company's public SEC filings which is incorporated by reference or included in, the Offer Documents (such supplied, derived, incorporated or included information, the "COMPANY SEC INFORMATION") and (ii) no representation, warranty or covenant is made or will be made herein by the Company with respect to information contained in the Offer Documents other than the Company SEC Information. (b) Parent, Purchaser and the Company will each promptly correct, and the Company agrees to notify Purchaser promptly as to, any information provided by them for use in the Offer Documents if and to the extent that it becomes false or misleading in any material respect and Parent and Purchaser will jointly and severally take all lawful action necessary to cause the Offer Documents as so corrected to be filed promptly with the SEC and to be disseminated to the Stockholders, in each case as and to the extent required by applicable Law. In conducting the Offer, Parent and Purchaser will comply in all material respects with the provisions of the Exchange Act and other applicable Laws. Parent and Purchaser will afford the Company and its counsel a reasonable opportunity to review and comment on the Offer Documents and any amendments thereto prior to the filing thereof with the SEC. 1.3. COMPANY ACTIONS. The Company hereby approves of and consents to the Offer and represents that (a) the Company Board (at a meeting duly called and held) has (i) determined that this Agreement, the Offer and the Merger are fair to and in the best interests of the Company and its Stockholders, (ii) approved this Agreement and the transactions contemplated hereby, including the Offer and the Merger, (iii) taken all other action necessary to render the limitations on control share acquisitions and business combinations contained in Sections 78.378 through 78.3793 and 78.411 through 78.444 of the NRS (or any similar provision) inapplicable to the transactions contemplated hereby, including the Offer and the Merger, and (iv) resolved to recommend acceptance of the Offer and approval of the Merger by the 4 Stockholders and adoption of this Agreement by the Stockholders and (b) Morgan Keegan & Company, Inc. (the "COMPANY FINANCIAL ADVISER") has delivered to the Company Board the opinion described in Section 3.20. The Company will use its reasonable best efforts to cause the Company Financial Adviser to permit the inclusion of the written opinion referred to in Section 3.20 in Schedule 14D-9 and the Proxy Statement and a reference to such opinion in the Offer Documents. The Company hereby consents to the inclusion in the Offer Documents of the recommendation referred to in this Section 1.3; PROVIDED, HOWEVER, that the Company Board may withdraw, modify or change such recommendation to the extent, and only to the extent and on the conditions, specified in Section 5.2(b). The Company will file with the SEC simultaneously with the filing by Parent and Purchaser of the Schedule 14D-1, a Solicitation/Recommendation Statement on Schedule 14D-9 (together with all amendments and supplements thereto, "SCHEDULE 14D-9") containing such recommendations of the Company Board in favor of the Offer and the Merger. The Company covenants to Parent and Purchaser that Schedule 14D-9 will comply in all material respects with the Exchange Act and any other applicable Laws and will contain (or will be amended in a timely manner so as to contain) all information that is required to be included therein in accordance with the Exchange Act and the rules and regulations thereunder and other applicable Laws; PROVIDED, HOWEVER, that (A) no representation, warranty or covenant is made or will be made herein by the Company with respect to information supplied by Parent or Purchaser expressly for inclusion in, or information derived from Parent's public SEC filings which is incorporated or included in, Schedule 14D-9 (the "PARENT SEC INFORMATION"), and (B) no representation, warranty or covenant is made or will be made herein by Parent or Purchaser with respect to information contained in Schedule 14D-9 other than the Parent SEC Information (which Parent SEC Information will include the information furnished by Parent as contemplated by the next sentence). The Company will include in Schedule 14D- 9 information furnished by Parent in writing concerning Parent's Designees as required by Section 14(f) of the Exchange Act and Rule 14f-1 thereunder and will use its reasonable best efforts to have Schedule 14D-9 available for inclusion in the initial mailing (and any subsequent mailing) of the Offer Documents to the Stockholders. Each of the Company and Parent will promptly correct any information provided by it for use in Schedule 14D-9 if and to the extent that it becomes false or misleading in any material respect and the Company will further take all lawful action necessary to cause Schedule 14D-9 as so corrected to be filed promptly with the SEC and disseminated to the Stockholders, 5 in each case as and to the extent required by applicable Law. Parent and its counsel will be given a reasonable opportunity to review Schedule 14D-9 and any amendments thereto prior to the filing thereof with the SEC. In connection with the Offer, the Company will promptly furnish Parent with mailing labels, security position listings and all available listings or computer files containing the names and addresses of the record Stockholders as of the latest practicable date and thereafter, until the expiration of the Offer, of those persons becoming Stockholders subsequent to such latest practicable date, and will furnish Parent such information and assistance (including updated lists of Stockholders, mailing labels and lists of security positions) as Parent or its agents may reasonably request in communicating the Offer to the record and beneficial Stockholders. Subject to the requirements of applicable Law, and except for such actions as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Offer and the Merger, Parent and Purchaser will, and will instruct each of their respective Affiliates, associates, partners, employees, directors, officers, agents, and advisors to, hold in confidence the information contained in such labels, lists and files, will use such information only in connection with the Offer and the Merger, and, if this Agreement is terminated in accordance with its terms, will deliver promptly to the Company (or destroy and certify to the Company the destruction of) all copies of such information (and any copies, compilations or extracts thereof or based thereon) then in their possession or under their control. 1.4. ACTIONS BY PARENT AND PURCHASER. Subject to the provisions of this Agreement, Parent shall provide or cause to be provided to Purchaser all of the funds necessary to purchase any shares of Common Stock that Purchaser becomes obligated to purchase pursuant to the Offer at such time as such funds are necessary. 1.5. DIRECTORS. (a) Promptly upon the purchase of Shares pursuant to the Offer, and from time to time thereafter, (i) Parent will be entitled to designate such number of directors ("PARENT'S DESIGNEES"), rounded up to the next whole number, as will give Parent, subject to compliance with Section 14(f) of the Exchange Act, representation on the Company Board equal to the product of (A) the number of directors on the Company Board (giving effect to any increase in the number of directors pursuant to this Section 1.5) and (B) the percentage that such 6 number of Shares so purchased bears to the aggregate number of Shares outstanding (such number being, the "BOARD PERCENTAGE"); PROVIDED, HOWEVER, that if the number of Shares purchased pursuant to the Offer equals or exceeds a majority of the outstanding Shares, the Board Percentage will in all events be a majority of the members of the Company Board, and (ii) the Company will, upon request by Parent, promptly satisfy the Board Percentage by (A) increasing the size of the Company Board or (B) using its reasonable best efforts to secure the resignations of such number of directors as is necessary to enable Parent's Designees to be elected to the Company Board, or both, and will use its reasonable best efforts to cause Parent's Designees promptly to be so elected, subject in all instances to compliance with Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. On or before November 12, 1999, the Parent shall provide to the Company the names of its designees for election to the Company Board and all other information relating to such designees necessary for the Company to comply with Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder.

At the request of Parent, the Company will take, at its expense, all lawful action necessary to effect any such election. Parent will supply to the Company in writing and be solely responsible for any information with respect to itself, Parent's Designees and Parent's officers, directors and Affiliates required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder to be included in Schedule 14D-9. Notwithstanding the foregoing, at all times prior to the Effective Time, the Company Board will include at least two Continuing Directors as defined in Section 1.5(b) below. The Company hereby represents that it has received the written resignations of the members of the Company Board for the purpose of satisfying its obligations under this Section 1.5(a). (b) Notwithstanding any other provision hereof, of the articles of incorporation or bylaws of the Company or of applicable Law to the contrary, following the election or appointment of Parent's Designees pursuant to this Section 1.5 and prior to the Effective Time, any amendment or termination of this Agreement by the Company or amendment of the articles of incorporation or bylaws of the Company, extension by the Company 7 for the performance or waiver of the obligations or other acts of Parent or Purchaser hereunder or waiver by the Company of any of the Company's rights hereunder will require the affirmative vote of the majority of the Continuing Directors. For purposes of this Agreement, the term the "CONTINUING DIRECTORS" means at any time (i) those directors of the Company who are directors on the date hereof and who voted to approve this Agreement and (ii) such additional directors of the Company who are not affiliated with Parent, Purchaser or any of their respective Affiliates and who are designated as "Continuing Directors" for purposes of this Agreement by a majority of the Continuing Directors in office at the time of such designation.

Upon completion of such filing or at such subsequent date or time as Parent and the Company agree and specify in the articles of merger, the Merger will become effective in accordance with the NRS. The time and date on which the Merger becomes effective is herein referred to as the "EFFECTIVE TIME." Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, immunities, powers and franchises of the Company will vest in the Surviving Corporation, and all debts, liabilities and duties of the Company will become the debts liabilities and duties of the Surviving Corporation. 2.4. ARTICLES OF INCORPORATION AND BYLAWS OF THE SURVIVING CORPORATION.

(b) The bylaws of the Surviving Corporation to be in effect from and after the Effective Time until amended in accordance with their terms, the articles of incorporation of the Surviving Corporation and the NRS will be the bylaws of Purchaser in effect immediately prior to the Effective Time. 2.5. DIRECTORS AND OFFICERS OF THE SURVIVING CORPORATION. (a) The members of the initial Board of Directors of the Surviving Corporation will be the members of the Board of Directors of Purchaser immediately prior to the Effective Time. All of the members of the Board of Directors of the Surviving Corporation will serve until their successors are duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the articles of incorporation and the bylaws of the Surviving Corporation. (b) The officers of the Surviving Corporation will consist of the officers of the Purchaser immediately prior to the Effective Time. Such Persons will continue as officers of the Surviving Corporation until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the articles of incorporation and the bylaws of the Surviving Corporation. 9 2.6. CONVERSION OF SECURITIES. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Purchaser, the Company or the holder of any of the following securities: (a) CONVERSION OF SHARES. Each Share issued and outstanding immediately prior to the Effective Time (other than any Shares to be canceled pursuant to Section 2.6(b) and any Dissenting Shares) and any Shares issuable upon exercise of any option, conversion or other right to acquire Shares existing immediately prior to the Effective Time (collectively, "RIGHTS") will, by virtue of the Merger and without any action on the part of the holder thereof, be canceled and extinguished and be converted into the right to receive the Per Share Amount, or such higher per Share amount as is paid in the Offer, in cash payable to the holder thereof, without interest (the "MERGER CONSIDERATION"), prorated for fractional shares, in accordance with Section 2.7. All such Shares, when so converted, will no longer be outstanding and will automatically be canceled and retired and will cease to exist, and each holder of a certificate formerly representing any such Share will cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor upon the surrender of such certificate in accordance with Section 2.7. Any payment made pursuant to this Section 2.6(a) and Section 2.7 will be made net of applicable withholding taxes to the extent such withholding is required by Law. Notwithstanding the foregoing, if between the date of this Agreement and the Effective Time the outstanding Shares shall have been changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares, the Merger Consideration will be correspondingly adjusted on a per-share basis to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares. (b) CANCELLATION OF TREASURY SHARES AND PARENT-OWNED SHARES. Each Share held in the treasury of the Company and each Share owned by Parent, Purchaser or any other direct or indirect wholly owned subsidiary of Parent immediately before the Effective Time (other than shares in trust accounts, managed accounts, custodial accounts and the like that are beneficially owned by third parties) will be automatically canceled and retired and will cease to exist and no payment or other consideration will be made with respect thereto. 10 (c) COMMON STOCK OF PURCHASER. Each share of common stock, par value $0.01 per share, of Purchaser issued and outstanding immediately before the Effective Time will be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation, which, in accordance with this Agreement, will constitute all of the issued and outstanding shares of capital stock of the Surviving Corporation immediately after the Effective Time. 2.7. SURRENDER OF SHARES; STOCK TRANSFER BOOKS. (a) Prior to the Effective Time, Purchaser will designate a bank or trust company selected by it and reasonably acceptable to the Company to act as agent for the Stockholders in connection with the Merger (the "EXCHANGE AGENT") to receive the funds necessary to make the payments contemplated by Section 2.6. When and as needed, Parent shall take all steps necessary to cause the Surviving Corporation, Purchaser or the Company to make available to the Exchange Agent for the benefit of Stockholders the aggregate consideration to which such holders will be entitled as and when such amounts are needed pursuant to Section 2.6(a). (b) Each holder of a certificate or certificates representing any Shares canceled upon the Merger pursuant to Section 2.6(a) (the "CERTIFICATES") may thereafter surrender such Certificate or Certificates to the Exchange Agent, as agent for such holder, to effect the surrender of such Certificate or Certificates on such holder's behalf for a period ending six months after the Effective Time. Parent agrees that promptly after the Effective Time it will cause the distribution to Stockholders of record as of the Effective Time of appropriate materials to facilitate such surrender. Upon the surrender of Certificates for cancellation, together with such materials, Parent will cause the Exchange Agent to pay the holder of such Certificates in exchange therefor cash in an amount equal to the Merger Consideration multiplied by the number of Shares represented by such Certificate. Until so surrendered, each such Certificate (other than certificates representing Shares to be canceled pursuant to Section 2.6(b) and any Dissenting Shares) will represent solely the right to receive the aggregate Merger Consideration relating thereto. (c) If payment of cash in respect of canceled Shares is to be made to a Person other than the Person in whose name a surrendered Certificate or instrument is registered, it will be a condition to such payment that the Certificate or instrument so 11 surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the Person requesting such payment shall have paid any transfer and other taxes required by reason of such payment in a name other than that of the registered holder of the Certificate or instrument surrendered or shall have established to the satisfaction of the Surviving Corporation or the Exchange Agent that such tax either has been paid or is not payable. (d) At the Effective Time, the stock transfer books of the Company will be closed and there will not be any further registration of transfers of Shares outstanding prior to the Effective Time or otherwise issuable pursuant to Rights on the records of the Company. If, after the Effective Time, Certificates are presented to the Surviving Corporation, they will be canceled and exchanged for the Merger Consideration as provided in Section 2.6(a). No interest will accrue or be paid on any cash payable upon the surrender of a Certificate or Certificates which immediately before the Effective Time represented outstanding Shares or Shares issuable upon exercise of Rights. (e) Promptly following the date that is six months after the Effective Time, the Exchange Agent will deliver to the Surviving Corporation all cash, certificates and other documents in its possession relating to the transactions contemplated hereby, and the Exchange Agent's duties will terminate. Thereafter, each holder of a Certificate (other than Certificates representing Shares to be canceled pursuant to Section 2.6(b) and any Dissenting Shares) may surrender such Certificate to the Surviving Corporation and (subject to applicable abandoned property, escheat and similar Laws) receive in consideration thereof the aggregate Merger Consideration relating thereto, without any interest or dividends thereon. (f) The Merger Consideration will be net to the holder of Shares in cash, subject to reduction only for any applicable federal back-up withholding or, as set forth in Section 2.7(c), stock transfer taxes payable by such holder. (g) In the event any Certificate has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration deliverable in respect thereof as determined in accordance with Section 2.6; 12 PROVIDED, that the Person to whom the Merger Consideration is paid shall, as a condition precedent to the payment thereof, give the Surviving Corporation a bond in such sum as the Surviving Corporation may direct or otherwise indemnify the Surviving Corporation in a manner satisfactory to it against any claim that may be made against the Surviving Corporation with respect to the Certificate claimed to have been lost, stolen or destroyed. (h) None of the Parent, Purchaser, the Company, the Surviving Corporation, the Exchange Agent or any other person shall be liable to any former holder of shares of Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. 2.8. STOCK PLANS. (a) Without limiting the generality or effect of Section 2.6 or 2.7 and notwithstanding the provisions hereof applicable to the Rights, the Company will use its reasonable best efforts (which include satisfying the requirements of Rule 16b-3(e) promulgated under Section 16 of the Exchange Act, without incurring any liability in connection therewith) to provide that, at the Effective Time, each holder of a then-outstanding option to purchase Shares under any of the Company's stock option plans described in Section 3.3 (the "STOCK OPTION PLANS"), whether or not then exercisable (the "OPTIONS"), will, in settlement thereof, receive from the Company for each Share subject to such Option an amount (subject to any applicable withholding tax) in cash equal to the difference between the Merger Consideration and the per Share exercise price of such Option to the extent such difference is a positive number (such amount being hereinafter referred to as, the "OPTION CONSIDERATION") and that all Options will be terminated and thereafter represent only the right to receive the Option Consideration; PROVIDED, HOWEVER, that with respect to any Person subject to Section 16(a) of the Exchange Act, any such amount will be paid as soon as practicable after the first date payment can be made without liability to such Person under Section 16(b) of the Exchange Act. Notwithstanding anything herein stated, no Option Consideration will be paid with respect to any Option unless, at or prior to the time of such payment, such Option is canceled and the holder of such Option has executed and delivered a release of any and all rights the holder had or may have had in respect of such Option. The Company will cooperate with Parent in developing and taking any actions reasonably designed to minimize the exercise of Options by the holders thereof prior to the Offer Completion Date. 13 (b) Without limiting the generality or effect of Sections 2.6 or 2.7 and notwithstanding the provisions hereof applicable to Rights, prior to the Effective Time, the Company will use its reasonable best efforts to obtain all necessary consents or releases from holders of Options under the Stock Option Plans and take all such other lawful action as may be necessary to give effect to the transactions contemplated by this Section 2.8. Except as otherwise agreed to by the parties, (i) the Stock Option Plans will terminate as of the Effective Time and the provisions in any other plan, program or arrangement providing for the issuance or grant of any other interest in respect of the capital stock of the Company or any Subsidiary thereof will be canceled as of the Effective Time and (ii) the Company shall use its best efforts to assure that following the Effective Time no participant in the Stock Option Plans or other plans, programs or arrangements shall have any right thereunder to acquire any equity securities of the Company, the Surviving Corporation or any Subsidiary thereof and to terminate all such plans and any Options or other Rights thereunder. 2.9 DISSENTING SHARES. (a) Notwithstanding any provision of this Agreement to the contrary, any Shares held by a holder who has not voted such Shares in favor of this Agreement and who has properly exercised dissenters' rights with respect to such Shares in accordance with the NRS (including Section 92A.380 thereof) and as of the Effective Time has neither effectively withdrawn nor lost its right to exercise such dissenters' rights ("DISSENTING SHARES"), will not be converted into or represent a right to receive the Merger Consideration pursuant to Section 2.6(a), but the holder thereof will be entitled to only such rights as are granted by the NRS. (b) Notwithstanding the provisions of Section 2.9(a), if any Stockholder who demands dissenters' rights with respect to its Shares under the NRS effectively withdraws or loses (through failure to perfect or otherwise) its dissenters' rights, then as of the Effective Time or the occurrence of such event, whichever later occurs, such holder's Shares will automatically be converted into and represent only the right to receive the Merger Consideration as provided in Section 2.6(a), without interest thereon, upon surrender of the Certificate or Certificates formerly representing such Shares. (c) The Company will give Parent (i) prompt notice of any written intent to demand payment of the fair value of any Shares, withdrawals of such demands and any other instruments served pursuant 14 to the NRS received by the Company and (ii) the opportunity to direct all negotiations and proceedings with respect to dissenters' rights under the NRS. The Company may not voluntarily make any payment with respect to any exercise of dissenters' rights and may not, except with the prior written consent of Parent, settle or offer to settle any such dissenters' rights. 2.10. SHORT FORM MERGER. Notwithstanding anything else in this Agreement to the contrary, at Parent's sole election, in the event that Purchaser shall acquire Shares, including Shares accepted for purchase pursuant to the Offer, in a number sufficient to consummate a merger of the Company into Purchaser pursuant to Section 92A.180 of the NRS, the parties hereto agree, at the request of Parent or Purchaser, to take all necessary and appropriate action to cause the merger of the Company with and into the Purchaser to become effective as soon as practicable after such acquisition, without approval of the Company's stockholders, in accordance with the terms of Section 92A.180 of the NRS. In such event, this Agreement shall be automatically amended, without any further action of any party hereto, to provide for the foregoing change and all references in this Agreement to the "Merger" shall refer to the merger of the Company with and into the Purchaser and the "Surviving Corporation" shall refer to the Purchaser as the surviving corporation in such Merger.

The Company has all requisite corporate power and authority to own, operate and lease its properties and carry on its business 15 as now conducted. The copies of the Company's articles of incorporation and Bylaws previously made available to Parent are true, correct and complete.

No fact or event has occurred which is 30 reasonably likely to affect adversely the qualified status of any such Company Benefit Plan or the exempt status of any such trust, except for any occurrence that could not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect, and all contributions to, and payments from, each Company Benefit Plan and Foreign Plan that are required to be made in accordance with such Plans and applicable Laws (including ERISA and the Code) have been timely made, other than any failures that could not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect. Each Company Benefit Plan intended to meet the requirements of Section 501(c)(9) of the Code meets such requirements in all material respects and provides no disqualified benefits (as defined in Section 4976(b) of the Code). (c) The Internal Revenue Service (the "IRS") has issued favorable determination letters with respect to the qualification of each qualified Company Benefit Plan and related trust, and the IRS has not taken any action to revoke any such letter and nothing has occurred, whether by action or failure to act, that could reasonably be expected to cause the loss of such qualification. The qualified Company Benefit Plans and trusts are set forth in Section 3.16(c) of the Company Disclosure Letter. (d) There are no leased employees within the meaning of Section 414(n) of the Code who perform services for the Company or any of its Subsidiaries. (e) No Company Benefit Plan is or at any time was (i) subject to Title IV of ERISA; (ii) subject to the minimum funding standards of Section 302 of ERISA or Section 412 of the Code; (iii) a "multiemployer plan" within the meaning of Section 3(37) or 4001(a)(13) of ERISA or Section 414(f) of the Code; or (iv) a "multiple employer plan" within the meaning of Section 413(c) of the Code. (f) No Company Benefit Plan or Foreign Plan provides medical benefits (whether or not insured) with respect to current or former employees, officers or directors after retirement or other termination of service, except as required by applicable Law. (g) Except as set forth on Section 3.16(g) of the Company Disclosure Letter, the consummation of the transactions contemplated by this Agreement will not, either alone or in 31 combination with another event, (i) entitle any current or former employee, officer or director of the Company to severance pay, unemployment compensation or any other payment or (ii) accelerate the time of payment or vesting, or increase the amount of compensation due any such employee, officer or director. (h) Neither the Company nor any of its Subsidiaries is a party to any agreement, contract or arrangement (including this Agreement) that could result, separately or in the aggregate, in the payment of any "excess parachute payments" within the meaning of Section 280G of the Code. No Company Benefit Plan provides for the reimbursement of excise taxes under Section 4999 of the Code or any income taxes under the Code. (i) With respect to each Company Benefit Plan and Foreign Plan, the Company has delivered or made available to Parent a true and complete copy of: (A) each writing constituting a part of such Company Benefit Plan or Foreign Plan, including, without limitation, all Company Benefit Plan and Foreign Plan documents and trust agreements; (B) the most recent Annual Report (Form 5500 Series) and accompanying schedule, if any; (C) the most recent annual financial report, if any; (D) the most recent actuarial report, if any; and (E) the most recent determination letter from the IRS, if any. Except as specifically provided in the foregoing documents delivered or made available to Parent, there are no amendments to any Company Benefit Plan or Foreign Plan that have been adopted or approved nor has the Company or any of its Subsidiaries undertaken to make any such amendments or to adopt or approve any new Company Benefit Plan or Foreign Plan. (j) Except as set forth on Section 3.16(j) of the Company Disclosure Letter, there are no pending or, to the Knowledge of the Company, threatened claims (other than claims for benefits in the ordinary course), lawsuits or arbitrations that have been asserted or instituted, or to the Company's Knowledge, no set of circumstances exists that may reasonably give rise to a claim or lawsuit, against the Company Benefit Plans or Foreign Plans, any fiduciaries thereof with respect to their duties to the Company Benefit Plans or Foreign Plans or the assets of any of the trusts under any of the Company Benefit Plans or Foreign Plans that could reasonably be expected to result in any liability of the Company or any of its Subsidiaries, other than any liability that could not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect. 32 (k) With respect to each Foreign Plan: (A) all amounts required to be reserved under each Foreign Plan have been so reserved in accordance with reasonable accounting practices prevailing in the country where such Foreign Plan is established; (B) each Foreign Plan required to be registered with a Governmental Entity has been registered and maintained in good standing with the appropriate Governmental Entities; and (C) the fair market value of the assets of each funded Foreign Plan that is a defined pension plan (or termination indemnity plan), and the liability of each insurer for each Foreign Plan that is a defined benefit pension plan (or termination indemnity plan) and is funded through insurance or the book reserve established for each Foreign Plan that is a defined benefit pension plan (or termination indemnity plan) that utilizes book reserves, together with any accrued contributions, is sufficient to procure or provide for the liability for accrued benefits with respect to those current and former employees of the Company and any of its Subsidiaries that participate in such Foreign Plan according to the reasonable actuarial or other applicable assumptions and valuations most recently used to determine employer contributions to or the funded status or book reserve of such Foreign Plans. (l) With respect to each Company Benefit Plan, there have been no prohibited transactions or breaches of any of the duties imposed on "fiduciaries" (within the meaning of Section 3(21) of ERISA) by ERISA with respect to the Company Benefit Plans that could reasonably be expected to result in any liability or excise tax under ERISA or the Code, other than any liability or Tax that could not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect. (m) All trusts providing funding for Company Benefit Plans that are intended to comply with Section 501(c)(9) of the Code are exempt from federal income taxation and, together with any other welfare benefit funds (as defined in Section 419(e)(1) of the Code) maintained in connection with any of the Company Benefit Plans, have been operated and administered in compliance with all applicable requirements such that neither the Company or any of its Subsidiaries, any Company Benefit Plan nor such trust or fund is subject to any taxes, penalties or other liabilities imposed as a consequence of failure to comply with such requirements, other than any liability or Tax that could not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect. 33 (n) All contributions, transfers, and payments in respect of any Company Benefit Plan, other than transfers incident to an incentive stock option plan within the meaning of Section 422 of the Code, have been or are fully deductible under the Code. (o) With respect to any insurance policy that provides funding for benefits under any Company Benefit Plan, to the Knowledge of the Company, no insurance company issuing any such policy is in receivership, conservatorship, liquidation or similar proceeding and, to the Knowledge of the Company, no such proceedings with respect to any insurer are imminent. 3.17.

NO BROKERS. The Company has not entered into any contract, arrangement or understanding with any Person or firm which may result in the obligation of the Company or Parent to pay any investment banker's or finder's fees, brokerage or agent's commissions or other like payments in connection with the negotiations leading to this Agreement or the consummation of the transactions contemplated hereby, except that the Company has retained the Company Financial Adviser as its financial advisor, the arrangements with which have been disclosed to Parent prior to the date hereof.

A "PARENT MATERIAL ADVERSE EFFECT" means any change, effect, event or condition that has had or could reasonably be expected to (i) have a material adverse effect on the business, assets, results of operations or financial condition of Parent, Purchaser and Parent's Subsidiaries, taken as a whole, or (ii) prevent or materially delay Parent's or Purchaser's ability to consummate the transactions contemplated hereby.
