BAHAM AGREEMENT This Agreement is made as of the 5th day of April, 1995 between Geodynamics Corporation, a California corporation ("Geodynamics") and Alney A. Baham ("Baham") (collectively "the Parties") with reference to the following facts: A. Baham is an employee of Geodynamics, most recently as a Senior Systems Engineer in Valley Forge, Pennsylvania, He has been suspended without pay since January 1, 1995. B. Baham, on behalf of himself, members of his family and his self-directed pension plan, is the beneficial owner of 34,900 shares of the Common Stock of Geodynamics (the "Geodynamics Stock") and is the holder of options to purchase approximately 9,100 additional shares of Geodynamics' Stock. C. From mid-1994 through the date of the Geodynamics Annual Meeting of Shareholders held on February 16, 195 (the "annual Meeting"), Baham conducted various proxy solicitations to the shareholders of Geodynamics including the presentation of an opposing slate of nominees for election to the Geodynamics Board of Directors (the "Board") at the Annual Meeting. In connection therewith, Geodynamics instituted legal proceedings against Baham and the other members of the opposing slate alleging, among other things, false and misleading solicitation materials. Baham contends that the election is null and void because Geodynamics made false and misleading statements in its proxy solicitation materials. Geodynamics and Baham each deny the allegations of wrongdoing made by the other. D. Geodynamics has raised objections concerning the voting of certain late proxies by Baham at the Annual Meeting, which objections the Inspector of Elections sustained. Baham has informed the Company that he believes the Inspector acted incorrectly. E. Geodynamics and Baham wish to resolve the various disputes which have arisen between them and to establish the guidelines respecting Baham's continued ownership of Geodynamics Stock and the continued relationship between Baham and Geodynamics. F. This settlement is the compromise of a disputed claim and neither the payment nor this Agreement is to be construed as an admission of liability on the part of any of the settling parties. In settling this matter, it is the desire of the parties to terminate the lawsuit between them and buy their peace. Accordingly, in consideration of the foregoing premises and the agreements contained herein, Geodynamics and Baham agree as follows: 1. Effective Date. Geodynamics shall be bound by the Agreement only if it and the Settlement Agreement of this same date are approved by a majority of the members of the Board of Geodynamics. The date Geodynamics' Board of Directors approves this Agreement shall be referred to as the "Effective Date." If no such approval is given, this Agreement shall be null and void. 2. Election of Directors. The parties acknowledge that Geodynamics has secured the resignations of Richard Smith and Frederick Evans, two of the six management nominees elected at the Annual Meeting, and has appointed Bruce Gordon and Will Stackouse, two members of the slate of nominees proposed by Baham at the Annual Meeting, to fill the vacancies created by those resignations. Geodynamics will use its best efforts to cause Messrs. Edleson, Gordon, and Stackhouse to be renominated and reelected to the Board at the 1995 Annual Meeting of Shareholders provided, however, that these directors may be identified as the last three candidates on the management slate if cumulative voting is employed. Baham hereby waives all of his rights to challenge the results of the election of directors at the Annual Meeting and agrees that he will not encourage or support any other shareholder making such a challenge. 3. Dismissal of Lawsuit; General Releases. (a) As soon as practicable following the Effective Date, Geodynamics shall dismiss with prejudice, and not reinstitute in any form, as to Baham and the other members of his slate the lawsuit currently pending in the United States District Court for the Central District of California, (Case No. CV-94-8335 LGB) entitled Geodynamics Corporation vs. Alney A. Baham, et al, (the "Lawsuit"). Prior to filing a request for dismissal, Geodynamics shall execute and file a stipulation and order seeking to vacate the existing preliminary injunction and temporary restraining order issued in the Lawsuit. (b) In consideration of the foregoing dismissal of the Lawsuit and the other agreements contained herein, Geodynamics, on the one hand, and Baham and Baham's spouse (by execution of a joinder concurrently herewith), on the other hand, on behalf of themselves, their successors, assigns, agents, heirs, administrators and representatives, each fully and forever release and discharge the other(s) of them and their respective officers, directors, employed, attorneys, agents, insurers, and affiliates from any and all cause or causes of actions, actions, judgments, liens, indebtedness, damages, losses, claims, liabilities, and demands of whatsoever kind or character, known or unknown, suspected to exist or not suspected to exist, anticipated or not anticipated, whether or not heretofore brought before any state or federal court or before any state or federal agency or other governmental entity, whether statutory or common law ("Claims") to the Effective Date, including without limitation on the generality of the foregoing, any and all claims, demands or causes of action attributable to, connected with or incidental to the annual Meeting, the election of directors at the Annual Meeting, the solicitation of proxies, the Lawsuit or otherwise. (c) IT IS EXPRESSLY UNDERSTOOD that California Civil Code Section 1542 provides as follows: A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor. THE PROVISIONS OF CALIFORNIA CIVIL CODE SECTION 1542 ARE HEREBY EXPRESSLY WAIVED BY EACH OF THE PARTIES HERETO to the fullest extent that a party may waive all such rights and benefits, if any, of such provisions pertaining to the matters released herein. In addition, each of the parties hereto hereby waives any similar provision in any other jurisdiction, if in any way applicable, and each of the parties hereto acknowledges that these waivers are an essential and material term of this Agreement. In connection with such waiver, each of the parties hereto acknowledges that such party has been advised of and has considered the possibility that such party may not now fully know the number or magnitude of all the Claims that such party may have against any other party hereto with respect to the matters released herein, and that such party may hereafter discover Claims presently unknown or unsuspected, or facts in addition to or different from those that such party now knows or believes to be true, with respect to the matters released herein. Nevertheless, it is each of the parties' intention, through this release, fully, finally, and forever to settle and release all such matters, and all Claims relative thereto, which may exist, or hereto have existed against the other, and each agrees that this release is such a full and final release. In furtherance of such intention, the release herein given shall be and remain in effect as a full and complete release of such additional or different Claims or facts relative thereto notwithstanding the discovery by such part of the existence of any additional or different Claims or facts relating to the Claims. 4. Agreements Respecting Geodynamics Stock and Future Relationships. With respect to the continuing relationship of Baham with Geodynamics and in consideration of the dismissal of the lawsuit and the other agreements herein, the parties agree as follows: (a) Irrevocable Proxy and Option. Baham hereby grants Geodynamics an option (the "Option") to purchase all shares of Geodynamics Stock beneficially owned by Baham, whether now owned or hereafter acquired and whether owned of record by Baham, members of his family, his self-directed pension trust, or any affiliate of the foregoing (the "Option Shares"), for the period commencing the date hereof and ending on March 1, 2000 (the "Option Period") at an exercise price of the greater of $10.00 over the fair market value of each share or two times the fair market value of each share on the date Geodynamics exercises that option. For purposes of this subparagraph and subparagraph 4 (c), fair market value shall mean the average of bid and ask on the NASDAQ system. In connection with the grant of the Option and to secure his obligations under subparagraph (d) below, concurrently herewith, Baham shall execute and deliver to Geodynamics an irrevocable proxy, in the form attached hereto as Exhibit A, to vote all the Option Shares during the Option Period. (b) Options. The parties acknowledge that all options to purchase shares of Geodynamics Stock currently held by Baham are hereby deemed expired on the Effective Date. (c) Right of First Refusal. If, at any time prior to March 1, 2000, Baham proposes to sell or offer for sale any shares of Geodynamics Stock then owned by him, including shares issued upon exercise of options (the "Shares"), he shall first offer the Shares for purchase by Geodynamics and shall advise Geodynamics as to the number of Shares being offered and the price proposed for such Shares. For a period of two (2) business days thereafter, or, in the case of a private sale of the Shares, for a period of five (5) business days, Geodynamics may accept such offer on the terms provided and either purchase or cause another person designated by it to purchase the Shares at the purchase price by company check or by certified check. If Geodynamics does not elect to purchase the Shares, Baham may sell the Shares in the market or consummate the private transaction. However, if the sale were to be at fair market value, and if the price has decreased from the time Baham first notified Geodynamics of the option to buy, Geodynamics shall pay Baham the difference between the price he receives for his Shares and the fair market value at the time he gave notice to the Company, provided Baham consummates the sale within two days of receiving notice from Geodynamics of its decision not to by the Shares. If Baham does not sell the Shares within two days, then Baham shall be free to sell such Shares at any time within 90 days thereafter so long as the price at which such Shares are sold is not less than the price offered to Geodynamics. Should the offering price be reduced or should the shares not be sold within such 90-day period, then Baham shall follow the foregoing procedure in connection with any subsequent offer to sell the Shares. (d) No Further Proxy Contest; Etc. Until March 1, 2000, Baham shall not purchase or otherwise acquire any additional shares of Geodynamics' Stock. In addition, until such date, Baham shall not, alone or with others, without the prior written consent of the Board specifically expressed in a resolution adopted by a majority of the members of the Board: (1) submit any proposal for the vote of shareholders of Geodynamics, seek the consent of Geodynamics' shareholders to any action, or seek to influence the vote of Geodynamics shareholders on any election of directors or other proposal submitted by management or others; (2) with respect to securities of Geodynamics, become a member of any "group" within the meaning of Section 13 (d) (3) of the Securities Exchange Act of 1934, as amended; (3) induce or attempt to induce, directly or indirectly, any other person to initiate or support any tender or exchange offer for Geodynamics Stock or any proposal for change of control of Geodynamics, whether in connection with a proxy contest or otherwise, or to offer or seek to cause any third party to offer to purchase the stock or substantially all of the assets of Geodynamics, whether by merger, tender offer or otherwise; (4) attempt to obtain election or appointment to the Board or to influence any decision of the Board (other than as set forth in Section 5 below); (5) take any action inconsistent with the foregoing; or (6) seek employment with Geodynamics or any current subsidiary or affiliate of Geodynamics. 5. Baham Expenses. Without in any way limiting the scope of subparagraph 3 (b) of this Agreement, Geodynamics agrees that, at the first meeting of the Board after the Effective Date, Geodynamics will place on the agenda a request by Baham to reimburse him for his expenses in conducting the proxy contest with respect to the Annual Meeting as compensation for what Baham views as services rendered to all shareholders and efforts to increase shareholder value. Baham will be entitled to make a presentation to the Board at that time and to contact any person (if such person is willing) before that meeting to campaign in favor of his request. The parties acknowledge that this Agreement does not create, and shall not be construed as creating, any legal obligation by Geodynamics with respect to such proposal and that Geodynamics has made no representations or warranties concerning the likelihood that such request will be honored. In the event reimbursement is denied by the Board, Baham will take no further action to seek reimbursement and, in particular, agrees that he will not institute any legal action against Geodynamics with respect thereto and will not seek to have the issue of reimbursement reconsidered by the Board. In the event that Geodynamics expands its Board of Directors beyond seven persons prior to the Board meeting at which this matter is considered, Geodynamics will delegate the authority to vote on the Baham proposal to a special committee composed of the seven directors serving on the Board immediately following the resignations and appointments referred to in paragraph 2 of this Agreement. 6. Miscellaneous. (a) Announcement; Non-Disclosure. Attached hereto as Exhibit B is a copy of the press release to be issued by the Parties on the Effective Date. Except as required to comply with the law, to consult with their financial and tax advisors, or to meet their contractual obligations, each party agrees to keep the terms of this Agreement confidential and agrees not to make, nor case to be made, any other news release, disclosure or public announcement pertaining to this Agreement or the subject matter hereof without the prior written approval of the other party.
