     WHEREAS, the Company and Executive have determined that it is in their respective best interest to enter into this Agreement on the terms and conditions as set forth below.

AGREEMENT

     NOW, THEREFORE, in consideration of the premises and the respective covenants and promises contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

     1. DEFINITIONS . In addition to the capitalized terms defined elsewhere herein, the following definitions shall be in effect under this Agreement:

          1.1 “Board” means the Company’s Board of Directors or the Compensation Committee thereof (or any other committee subsequently granted authority by the Board), subject to Section 5.6.

          1.2 “Cause” means (i) Executive’s failure to substantially perform his duties and responsibilities as described herein or as otherwise designated by the Board within 30 days after written demand for substantially improved performance is delivered to Executive identifying the manner in which the Company believes Executive has not substantially performed such duties and responsibilities, (ii) Executive’s willful misconduct amounting to fraud or dishonesty which is materially injurious to the Company or its subsidiaries, monetarily or otherwise, (iii) a violation by Executive of his responsibility to maintain non-public information confidential, including Executive’s breach of that certain Employee Patent and Proprietary Information Agreement dated June 16, 2006, between the Company and Executive, attached hereto as Exhibit A (the “EPPI”), which is materially injurious to the Company or (iv) any violation of the Company’s Code of Ethics, as the same may be amended from time to time, which is materially injurious to the Company.

          1.3 “Change in Control” shall be deemed to have occurred if:

               1.3.1 any “person,” as such term is used in Section 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (other than the Company, any trustee or other fiduciary holding securities under an employee benefit plan of the

Company, or any company owned, directly or indirectly, by the shareholders of the Company in substantially the same proportions as their ownership of stock of the Company) together with its “Affiliates” and “Associates”, as such terms are defined in Rule 12b-2 of the Exchange Act, is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 40% or more of the combined voting power of the Company’s then outstanding securities;

               1.3.2 individuals who were the Board of Directors’ nominees for election as directors of the Company (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction described in subsections 1.3.1, 1.3.3 or 1.3.4 of this definition) immediately prior to a meeting of the shareholders of the Company involving a contest for the election of directors shall not constitute a majority of the Board of Directors following the election;

               1.3.3 the shareholders of the Company approve a merger or consolidation of the Company with any other company other than (a) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than 80% of the combined voting power of the voting securities of the Company (or such surviving entity) outstanding immediately after such merger or consolidation or (b) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no “person” (as hereinabove defined) acquires more than 40% of the combined voting power of the Company’s then outstanding securities; or

               1.3.4 the shareholders of the Company adopt a plan of complete liquidation of the Company or approve an agreement for the sale, exchange or disposition by the Company of all or a significant portion of the Company’s assets. For purposes of this subsection 1.3.4, the term “the sale, exchange or disposition by the Company of all or a significant portion of the Company’s assets” shall mean a sale or other disposition transaction or series of related transactions involving assets of the Company or any subsidiary of the Company (including the stock of any subsidiary of the Company) in which the value of the assets or stock being sold or otherwise disposed of (as measured by the purchase price being paid therefore or by such other method as the Board reasonably determines is appropriate in a case where there is no readily ascertainable purchase price) constitutes more than 50% of the fair market value of the Company (as hereinafter defined). For purposes of the preceding sentence, the “fair market value of the Company” shall be the aggregate market value of the outstanding shares of the Company’s common stock (including shares issuable upon the exercise of in-the-money stock options) plus the aggregate market value of the Company’s other outstanding equity securities. The aggregate market value of the shares of the Company’s common stock shall be determined by multiplying the number of shares of the Company’s common stock (including shares issuable upon the exercise of in-the-money stock options) outstanding on the date of the execution and delivery of a definitive agreement with respect to the transaction or series of related transactions (the “Transaction Date”) by the average closing price of the shares of the Company’s common stock for the ten trading days immediately preceding the Transaction Date. The aggregate market value of any other equity securities of the Company shall be determined in a manner similar to that prescribed in the immediately preceding sentence for determining the aggregate market value of

 

the shares of the Company’s common stock or by such other method as the Board shall reasonably determine is appropriate.

          1.4 “Good Reason” shall mean any of the following:

               1.4.1 the failure of the Company to pay or cause to be paid Executive’s Base Salary when due hereunder;

               1.4.2 a 10% or greater reduction of the Executive’s Base Salary;

               1.4.3 a material reduction in Executive’s target annual bonus award (as set forth in Section 2.4.2 below);

               1.4.4 a material reduction in the equity compensation or other employee benefits paid to Executive, such that such equity compensation or employee benefits are inconsistent with those paid to other executive officers of the Company;

               1.4.5 a material diminution in the Executive’s duties, authority or responsibilities;

               1.4.6 a relocation of the Executive to a location more than fifty (50) miles from his home without Executive’s prior consent; or

               1.4.7 in the event of a Change in Control, the failure of the Company to obtain the agreement from any successor to assume, and agree to, this Agreement; provided, that, any of the events described in Sections 1.4.1, 1.4.2, 1.4.3, 1.4.4 and 1.4.5 shall constitute Good Reason only if the Company fails to cure such event within 30 days after receipt from the Executive of written notice of the event which constitutes Good Reason and, provided further, that such notice is given within 30 days after Executive obtains knowledge that such events occurred.

     2. EMPLOYMENT AND DUTIES.

          2.1 Term. The Company hereby agrees to employ Executive as President and COO, and Executive hereby accepts such employment commencing as of June 8, 2007 (the “Effective Date”). Executive acknowledges that his employment with the Company is for no specified period of time and constitutes “at-will” employment, which means that Executive’s employment may be terminated at any time, upon written notice to the other party, for any reason, or for no reason, at the option of either the Company or Executive, subject to the provisions of Section 2.5 below. Except as otherwise provided herein, this Agreement supersedes and terminates any and all prior agreements, discussions, and writings between Executive and any representative of the Company concerning and/or relating to Executive’s employment.

          2.2 Position. Executive shall serve as the President and COO of the Company and shall report directly to the Chief Executive Officer (the “Service”). At the Company’s request, Executive shall serve the Company’s subsidiaries and affiliates in other offices and capacities in addition to the foregoing. If Executive serves any one or more of such additional

capacities, Executive’s compensation and benefits shall not be increased beyond that provided in Section 2.4. Further, if Executive’s service in one or more of such additional capacities is terminated, such termination shall not constitute a termination by the Company for Cause and Executive’s compensation and benefits provided herein shall not be reduced for so long as Executive otherwise remains employed by the Company under the terms of this Agreement.

          2.3 Duties. Executive shall have the authority and perform the duties customarily associated with his title and office, together with such additional duties of a company officer nature and commensurate with Executive’s title as may from time to time be assigned by the Board. While employed by the Company, Executive shall devote his full working time and best efforts to the performance of his duties and the furtherance of the interests of the Company and shall not be otherwise employed. Executive may not serve as an officer or director of, or otherwise be employed by or participate in, any other entity without the prior written consent of the Company; provided that, so long as it does not interfere with Executive’s employment, Executive may (a) with the prior written consent of the Company, serve as a director in a non-competing company, (b) serve as an officer, director, or otherwise participate in a purely educational, welfare, social, religious, or civic organization, and (c) manage personal and family investments.

In consideration of the Service rendered to the Company hereunder by Executive, the Company shall pay Executive a base salary per annum of Two Hundred Twenty-Five Thousand Dollars ($225,000), less applicable statutory deductions and withholdings (the “Base Salary”), payable in accordance with the Company’s regular payroll procedures as presently in effect and as may be amended from time to time; provided, however, that Executive will receive a base salary per annum of Two Hundred Thousand Dollars ($200,000) until the last regularly scheduled pay date of 2007, after which such time Executive will receive the Base Salary rate. The Company, by action of its Board or the Compensation Committee, may increase Executive’s Base Salary at any time and from time to time.

               2.4.2 Annual Bonus. Executive shall be eligible for an annual cash bonus payment with a target amount of 50% of Base Salary but with the potential for a bonus of up to 150% of Base Salary for extraordinary performance as such is to be determined pursuant to the Company’s executive performance program and as approved by the Board or Compensation Committee. Based on Executive’s performance as measured against the executive performance program, Executive may earn an annual bonus in a range from 0% to 150% of Base Salary. Subject to the provisions of Section 2.5, however, Executive shall not be entitled to any bonus payment unless Executive is employed by the Company on the date such bonus payments are to be made.

               2.4.3 Stock Options. Executive shall:

                    (i) receive on the date hereof, in accordance with the terms of the Qualified Stock Option Agreement/O.I. Corporation 2003 Incentive Compensation Plan (the “Plan”), a stock option to purchase up to 20,000 shares of the Common Stock of the Company, which shares shall vest over a four-year period (the “Stock Option”). The Stock Option shall

                    (ii) be eligible on an annual basis to receive, pursuant to the Company’s executive performance program as approved by the Board or Compensation Committee, in accordance with the terms of the Plan or such other stock option plan as may be adopted by the Board and amended from time to time at the sole discretion of the Board, a stock option to purchase up to 25,000 shares of the Company’s Common Stock, which shares shall vest over a four-year period. Upon any change in control, any additional stock options shall vest in the manner set forth in the stock option plan pursuant to which such stock option is granted.

                    (iii) Expenses. The Company shall pay or reimburse Executive for all reasonable and necessary out-of-pocket expenses actually incurred by Executive in the performance of Executive’s Services under this Agreement, provided Executive provides proper records and/or receipts for such expenses and otherwise properly accounts for such expenses in accordance with the Company’s reimbursement policies as presently in effect and amended from time to time.

                    (iv) D&O Insurance Coverage. Executive shall be entitled to director and officer insurance coverage for his acts and omissions while employed as an officer and director of the Company on a basis no less favorable to him than the coverage provided to all other similarly situated officers and directors.

          2.5 Termination.

               2.5.1 Termination For Cause. The Board may terminate Executive’s employment for Cause. Such termination shall be communicated by the delivery of a notice of termination to Executive in accordance with Section 5.1 and shall be effective as of the date of delivery of the notice of termination. Executive shall have no right to receive any compensation including, without limitation, bonus, on and after the effective date of such termination other than the following as of the date of termination: (A) Executive’s Base Salary then in effect which has been earned but unpaid; (B) vested benefits under any employee benefit plan then in effect and applicable to Executive; (C) any benefits to which Executive is entitled under law; and (D) any expenses which are reimbursable under this Agreement and incurred prior to the date of

a)

to communicate to the Company or its nominee promptly and fully all inventions or discoveries made, conceived, or reduced to practice, by me (whether made, conceived, or reduced to practice solely by me or jointly with others) from the time of entering the Company’s employ until I leave, (1) which relate in any respect to the lines of the business, work or investigations of the Company or of companies which it owns or controls at the time of such inventions or discoveries, or (2) which result from or are suggested by any work which I may do for or on behalf of the Company;

b)

to assign to the Company such inventions or discoveries and all patents which may be issued thereon (in any and all countries where issued), and to assist the Company, during and subsequent to such employment, in every reasonable manner (entirely at the Company’s expense) in obtaining the rights to and benefit of such inventions, discoveries and patents;

c)

to keep and maintain adequate and current written records of all such inventions or discoveries in the form of notes, sketches, drawings, or reports relating thereto, which records shall be and remain the property of the Company or the Government, as the case may be, and shall be available to the Company or its nominee at all times;

d)

except as the Company may otherwise consent, in writing, not to use except for the benefit of the Company or disclose at any time either during or subsequent to my employment to persons outside of the Company or other employees within the Company not authorized to have access to such, any confidential, trade secret, or proprietary information of the Company or of companies which it owns or controls (“O.I.

If I determine that I am being placed in a position in the Company where my duties and my loyalties to the Company might cause me, even in the best

of good faith, to use or disclose the confidential or proprietary information of another, I will promptly inform a superior in writing so that appropriate actions may be considered and/or taken.

I further confirm that I am not restricted by any prior employee agreement from taking the position or assuming the duties for which I am being employed.
