SECTION 8. Noncompetition, Nonsolicitation, Nondisclosure. In consideration of Purchaser's agreement to purchase the Stockholder's Shares pursuant to the Offer and Parent's and Purchaser's agreement to enter into this Agreement and the Merger Agreement, and as a condition thereto, the Stockholder covenants and agrees as follows:

(a) Non-Competition. During the period commencing on the date upon which the Purchaser or any of its Affiliates purchases Shares pursuant to the Offer (the "Purchase Date") and ending on the fifth anniversary thereof (the "Restricted Period"), the Stockholder shall not, directly or indirectly through another Person, own any interest in, manage, control, participate in (whether as an owner, operator, manager, consultant, officer, director, employee, partner, investor, agent, representative or otherwise), consult with, render services for, or otherwise engage anywhere in any business engaged directly or indirectly in manufacturing, marketing or selling liquid or solid sodium cyanide or other cyanide salt products, equipment or consultancy services, or in any other business in which the Company or any of its Subsidiaries has engaged at any time within the two-year period immediately preceding the Purchase Date; provided that nothing in this Section 8(a) shall prevent the Stockholder from being a passive owner of not more than 1% of the outstanding stock of any class of a corporation which is publicly traded so long as none of such Persons has any active participation in the business of such corporation. The Stockholder acknowledges that the restrictions set forth above are reasonable and necessary to protect the goodwill of the Company's and its Subsidiaries' businesses being sold pursuant to the Merger Agreement.

(b) Non-Solicitation. During the Restricted Period, the Stockholder shall not, directly, or indirectly through another Person, (i) induce or attempt to induce any employee of the Company or any of its Subsidiaries to leave the employ of the Company or any of its Subsidiaries, or in any way interfere with the relationship between the Company or any of its Subsidiaries and any employee thereof, (ii) hire or otherwise retain for services any person who was an employee of Cyanco at any time during the one-year period immediately prior to the Purchase Date, or (iii) call on, solicit or service any customer, supplier, licensee, licensor, lessor or other business relation of the Company or any of its Subsidiaries (including any Person that was a customer or supplier or other potential or

prospective business relation of the Company or any of its Subsidiaries at any time during the one-year period immediately prior to such call, solicit or service), induce or attempt to induce such Person to cease doing business with the Company or any of its Subsidiaries, or in any way interfere with the relationship between any such customer, supplier, licensee, business relation, or other potential or prospective business relation and the Company or any of its Subsidiaries (including making any negative statements or communications about the Company or any of its Subsidiaries or any of their respective stockholders, directors, officers or employees).

(c) Nondisclosure. The Stockholder agrees that, from and after the Purchase Date, he shall (and shall cause his Affiliates, agents, advisors, counsel and other representatives to) treat and hold as confidential all information concerning the businesses and affairs of the Company or any of its Subsidiaries (including all Intellectual Property of the Company and its Subsidiaries) (the "Confidential Information") and, except as otherwise expressly permitted by this Agreement, refrain from using any of the Confidential Information and, upon the request of Parent at any time after the Purchase Date, deliver promptly to Parent or destroy all tangible embodiments (and all copies) of the Confidential Information which are in the Stockholder's possession or otherwise under the Stockholder's control. In the event that the Stockholder or any of his Affiliates, agents, advisors, counsel or other representatives is requested or required (by oral question or request for information or documents in any legal proceeding, interrogatory, subpoena, civil investigative demand, or similar process) to disclose any Confidential Information, the Stockholder shall notify Parent promptly of the request or requirement so that Parent may seek an appropriate protective order or waive compliance with the provisions of this Section 8(c). If, in the absence of a protective order or the receipt of a waiver hereunder, the Stockholder or any of his Affiliates, agents, advisors, counsel or other representatives is, on the advice of counsel, compelled to disclose any Confidential Information to any tribunal or else stand liable for contempt, such Person may disclose the Confidential Information to the tribunal; provided that such Person shall use best efforts to cooperate with Parent in obtaining, at the request and expense of Parent, an order or other assurance that confidential treatment shall be accorded to such portion of the Confidential Information required to be disclosed as Parent shall designate. Notwithstanding the foregoing, for purposes of this Agreement, Confidential Information shall not include information which is or becomes generally available to the public other than as a result of a disclosure by the Stockholder or any of his Affiliates, agents, advisors, counsel or other representatives in violation of this Agreement.

(d) Acknowledgments. If, at the time of enforcement of the covenants contained in this Section 8 (the "Restrictive Covenants"), a court shall hold that the duration, scope or area restrictions stated herein are unreasonable under circumstances then existing, the parties agree that the maximum duration, scope or area reasonable under such circumstances shall be substituted for the stated duration, scope or area and that the court shall be allowed and directed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by law. The Stockholder has consulted with legal counsel regarding the Restrictive Covenants and based on such consultation has determined and hereby acknowledges that the Restrictive Covenants are reasonable in terms of duration, scope and area restrictions and are necessary to protect the goodwill of the Company's and its Subsidiaries' businesses and the substantial investment in the Company made by Parent and Purchaser pursuant to the Merger Agreement. The Stockholder further acknowledges and agrees that the Restrictive Covenants are being entered into by him in connection with the proposed sale of Stockholder's Shares pursuant to the Merger Agreement and not directly or indirectly in connection with the Stockholder's employment or other relationship with the Company or any of its Subsidiaries.

SECTION 9. General Release. Effective as of immediately prior to the purchase of Shares by the Purchaser or any of its Affiliates pursuant to the Offer, the Stockholder, on behalf of himself and his successors, assigns, next-of-kin, representatives, administrators, executors, Affiliates, stockholders, members, partners, directors, managers, officers, employees and agents, and any other person or entity claiming by, through, or under any of the foregoing, does hereby unconditionally and irrevocably release, waive and forever discharge each of Purchaser, Parent, the Company and each of their respective past and present stockholders, members, partners, directors, managers, officers, employees,

agents, predecessors, successors, assigns, insurers and Affiliates (collectively, the "Released Parties"), from any and all claims, demands, damages, judgments, causes of action, obligations and liabilities of any nature whatsoever, whether or not known, suspected or claimed, arising directly or indirectly from any act, omission, event or transaction occurring (or any circumstances existing) at or prior to the Effective Time, including without limitation, any and all of the foregoing arising out of or relating to (a) the Stockholder's capacity as a current or former stockholder, member, partner, director, manager, officer, employee or agent of any of the Released Parties or any of their respective predecessors, successors, assigns or affiliates (or the Stockholder's capacity as a current or former stockholder, member, partner, director, manager, officer, employee or agent of any other entity in which capacity the Stockholder is or was serving at the request of any of the Released Parties), or (b) any contract, agreement or other arrangement (whether verbal or written) (other than the Merger Agreement or this Agreement) entered into or established at or prior to the Effective Time (with the effect that any such contract, agreement or other arrangement, including any provision purporting to survive termination of such contract, agreement or other arrangement, is hereby terminated in its entirety effective as of the Effective Time), in all cases whether or not known, suspected or claimed, arising directly or indirectly from any act, omission, event or transaction occurring (or any circumstances existing) at or prior to Effective Time. The Stockholder understands that this is a full and final general release of all claims, demands, causes of action, obligations and liabilities of any nature whatsoever, whether or not known, suspected or claimed, that could have been asserted in any legal or equitable proceeding against any of the Released Parties. Notwithstanding this Section 9, each of Parent, Purchaser and the Company shall remain liable with respect to any liabilities or obligations such Released Party has to the Stockholder pursuant to the Merger Agreement (as to Stockholders of the Company generally) or this Agreement.

All notices, requests, demands and other communications hereunder shall be in writing and shall be given (and shall be deemed to have been duly given upon receipt) by delivery in Person, by facsimile or by registered or certified mail (postage prepaid, return receipt requested) or by a nationally recognized overnight courier service to the respective parties at the following addresses (or

Wherever the words "include," "includes" or "including" are used in this Agreement, they shall be deemed to be followed by the words "without limitation." This Agreement and any documents or instruments delivered pursuant hereto or in connection herewith shall be construed without regard to the identity of the Person who drafted the various provisions of the same. Each and every provision of this Agreement and such other documents and instruments shall be construed as though all of the parties participated equally in the drafting of the same. Consequently, the parties acknowledge and agree that any rule of construction that a document is to be construed against the drafting party shall not be applicable to this Agreement or such other documents and instruments.

(c) Counterparts. This Agreement may be executed manually or by facsimile or electronic mail by the parties hereto, in any number of counterparts, each of which shall be considered one and the same agreement and shall become effective when a counterpart hereof shall have been signed by each of the parties and delivered to the other parties.

(d) Entire Agreement. This Agreement constitutes the entire agreement among the parties with respect to the subject matter hereof and supersedes all other prior agreements and understandings, both written and oral, among the parties or any of them with respect to the subject matter hereof. This Agreement is not intended and does not confer upon any person other than the parties hereto any rights hereunder.

(e) Governing Law.

(f) Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties except that Parent and Purchaser may assign, in their sole discretion and without the consent of any other party, any or all of their rights, interests and obligations hereunder to each other or to one or more direct or indirect wholly-owned subsidiaries of Parent (each, an "Assignee"). Any such Assignee may thereafter assign, in its sole discretion and without the consent of any other party, any or all of its rights, interests and obligations hereunder to one or more additional Assignees. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by, the parties and their respective successors and assigns, and the provisions of this Agreement are not intended to confer upon any person other than the parties hereto any rights or remedies hereunder.

(g) Severability of Provisions. If any term or provision of this Agreement is invalid, illegal or incapable of being enforced by rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions are fulfilled to the extent possible.

(h) Specific Performance; Non-Exclusivity. The Stockholder acknowledges and agrees that money damages will not be an adequate remedy for any breach or threatened breach of the provisions of this Agreement and that, in such event, Parent, Purchaser and/or their respective successors or assigns shall, in addition to any other rights and remedies existing in their favor, be entitled to specific performance, injunctive and/or other relief from any court of competent jurisdiction in order to enforce or prevent any violations of the provisions of this Agreement (including the extension of the Restricted Period with respect to the Stockholder by a period equal to the length of the court proceedings necessary to stop such violation).

The rights and remedies of Parent and Purchaser hereunder are not exclusive of or limited by any other rights or remedies that Parent and Purchaser may have, whether at law, in equity, by contract or otherwise, all of which shall be cumulative (and not alternative).

(i) Amendment. No amendment, modification or waiver in respect of this Agreement shall be effective against any party unless it shall be in writing and signed by such party.

(j) Binding Nature. This Agreement is binding upon and is solely for the benefit of the parties hereto and their respective successors, legal representatives and permitted assigns.
