Exhibit 10.23 EMPLOYMENT AGREEMENT THIS AGREEMENT, made and entered into as of August 19, 1993, and as amended as of November 12, 1993, by and between Home Office Reference Laboratory, Inc., with offices in Lenexa, Kansas (hereinafter referred to as "HORL") and Kenneth A. Stelzer, a resident of the State of Kansas (hereinafter referred to as "Officer"); WITNESSETH: WHEREAS, Officer and HORL are presently parties to an Employment Agreement, dated August 3, 1983, and a Termination Compensation Agreement, dated February 28, 1990; WHEREAS, HORL wishes to offer additional consideration to Officer to induce Officer to continue in the employment of HORL; and WHEREAS, it is the intention and desire of the parties to enter into a formal agreement whereby three principal purposes will be served, to wit: A. The present Employment Agreement and Termination Compensation Agreement between the parties will be cancelled in their entirety and this Employment Agreement will be substituted in their place and stead; and B. HORL will have the benefit of the substantial expertise of Officer for at least the period covered by this Agreement; and C. Officer will serve HORL during the term hereinafter defined and will be motivated by the additional consideration set forth herein; NOW, THEREFORE, in consideration of the employment of Officer by HORL and of the mutual promises, covenants, representations and warranties contained herein, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree that the present Employment Agreement and Termination Compensation Agreement between the parties are hereby cancelled in their entirety and the following Employment Agreement (the "Agreement") is hereby substituted in their place and stead: SECTION I EMPLOYMENT AND TERM 1.1 Employment. HORL hereby employs Officer and Officer hereby accepts such employment and agrees to perform the duties described in Section 2 of this Agreement. 1.2 Term. (a) Base Term. The term of employment shall commence on the date of this Amendment to Employment Agreement and shall continue for a period of two (2) years therefrom (the "Base Term"), or until terminated as otherwise provided herein. (b) Termination Subsequent to Change in Control. Notwithstanding any other provision of this Agreement to the contrary, in the event that (i) a change of control of HORL shall occur at any time during which Officer is in the full-time employment of HORL or its successor and (ii) within one (1) year after such a change in control, Officer's employment with HORL or its successor is terminated by HORL or its successor for any reason other than permanent disability, death or normal retirement, or is voluntarily terminated by Officer for any reason at his sole discretion, HORL will promptly pay to Officer as termination compensation the lump sum amount described below. The lump sum compensation payable shall be equal to three (3) times the average annual compensation includable in Officer's gross income for the most recent five (5) taxable years ending before the date of the change in control. If Officer has been an employee of HORL for less than 5 years, Officer's lump sum payment shall be equal to 3 times the average annual compensation includable in Officer's gross income based on the portion of the 5 year period during which Officer performed services for HORL. To the extent that any amount required to be paid hereunder would constitute an "excess parachute payment" within the meaning of Section 280G(b) of the Internal Revenue Code of 1986, that excess amount need not be paid. For purposes of this Section 1.2(b), a "change of control" shall be deemed to have taken place if there shall have occurred (i) the sale or other disposition resulting in the transfer of legal or beneficial ownership of, or the right to vote, more than fifty percent (50%) of the outstanding capital stock of HORL to one or more third-party purchasers unaffiliated with Seafield Capital Corporation, its shareholders or affiliates (as the term "affiliate" is defined in Rule 12b-2 promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934), except in connection with an underwritten public offering of the common stock of HORL, (ii) a merger or consolidation of HORL with or into any entity other than Seafield Capital Corporation or its affiliates, or (iii) a sale or other transfer of substantially all of the assets of HORL to any person or entity other than Seafield Capital Corporation or its affiliates. In the event of termination of employment under the circumstances described above, HORL shall pay to Officer the installments of his base salary through the date of termination of employment, any annual incentive bonus for the previous year if such has been approved but not paid and the lump sum amount as termination compensation described above, and any remaining term of this Agreement shall be cancelled. Such payments to Officer and the arrangements provided for by any stock option or other agreement between HORL and Officer in effect at the time and by any other applicable plan of HORL will constitute the entire obligation of HORL to Officer with respect to such termination, and will also constitute full settlement of any claim under law or in equity that Officer might otherwise assert against HORL or any of its employees on account of such termination. (c) Annual Extension. Commencing on the second anniversary of this Agreement and on each succeeding anniversary thereafter, unless HORL notifies Officer in accordance with the immediately following sentence that Officer's employment under this Agreement will not be extended, this Agreement and Officer's employment under this Agreement shall automatically and without further action be extended for one (1) year from such anniversary on the same terms and conditions as are set forth herein. If HORL elects not to extend Officer's employment under this Agreement as provided in the preceding sentence, it shall do so by notifying Officer in writing at least sixty (60) days prior to the applicable anniversary date of this Agreement. If HORL elects not to extend Officer's employment under this Agreement as provided above, such election shall be treated as a termination of Officer without cause within the meaning of Section 9.1(e) of this Agreement and HORL shall pay to Officer, in addition to any other sums which may be due to Officer, the lump sum severance payment provided for in Section 9.1(e). SECTION 2 DUTIES 2.1 General Duties. Stelzer herewith resigns as President and Chief Executive Officer of HORL.

(d) A "termination of Optionee's employment by HORL without cause" shall occur in the event that Optionee's employment is terminated by HORL for any reason other than the following actions, failures or events by or affecting Optionee which shall constitute "cause" for termination of Optionee by HORL: (i) willful and continued failure by Optionee to substantially perform his duties provided in the Employment Agreement between Optionee and HORL, dated , 1993, after a written demand for substantial performance is delivered to Optionee by the Board of Directors of HORL, which demand identifies with reasonable specificity the manner in which Optionee has not substantially performed his duties, and Optionee fails to comply with such demand within a reasonable time; (ii) the engaging by Optionee of gross misconduct or gross negligence materially injurious to HORL; (iii) Optionee's conviction of having committed a felony; or (iv) HORL's fiscal year earnings from operations (excluding investment income and provision for income taxes) determined in accordance with generally accepted accounting principles (excluding extraordinary, unusual or nonrecurring gains or losses), shall be less than $14,000,000. Notwithstanding the foregoing, Optionee shall not be deemed to have been terminated by HORL for cause unless and until there shall have been delivered to him a copy of a resolution duly adopted by the affirmative vote of not less than a majority of the entire membership of the Board of Directors of HORL finding that, in the good faith opinion of the Board of Directors, HORL has cause for the termination of employment of Optionee as set forth in any of clauses (i) through (iv) above and specifying the particulars thereof in reasonable detail.

SECTION 5 NON-COMPETITION 5.1 Restrictive Covenants. In consideration for Officer's employment with HORL and in further consideration for the compensation provided to Officer in Sections 3 and 4 hereof, Officer agrees that during the term of his employment pursuant to this Agreement, and for a period of two (2) years after the termination for any reason of his employment pursuant to this Agreement, he will not, without the prior written consent of HORL, directly or indirectly, individually or in concert with others, or through the medium of any other corporation, partnership, syndicate, association, joint venture, or other entity or as an employee, officer, director, agent, consultant or affiliate, compete with HORL, within the hereinafter described region, in (i) the urine or blood chemistry testing or analysis business for the insurance industry, or (ii) the urine or blood chemistry container or other supply business for the insurance industry, or (iii) any other business engaged in by HORL as of the date of the termination of Officer's employment with HORL, and Officer will not solicit or accept any such business described in any of subparts (i) through (iii) above and which competes with HORL from any customer who is served by HORL as of the date of the termination of Officer's employment pursuant hereto, or cause or induce any present or future employee of HORL to leave the employ of HORL to accept employment with Officer or with any such entity or person. The region referred to above shall consist of any territory in which HORL or any of its representatives or agents, as of the date of the termination of Officer's employment pursuant hereto, provides, sells, offers for sale or solicits the sale of urine or blood chemistry testing or analysis, or urine or blood chemistry containers or other supplies related thereto, or other services or products. HORL and Officer agree that in the event that any provision of this Section 5.1 is void or constitutes an unreasonable restriction against Officer, such provision shall not be rendered void, but shall apply with respect to such time or territory or to such other extent as may constitute a reasonable restriction under the circumstances. The foregoing provisions shall not prohibit Officer from owning not more than 3% of the total shares of all classes of stock outstanding of any publicly held company. 5.2 Injunctive Relief.

Nothing in this Section 5 shall be construed as preventing Officer from engaging in charitable, professional, religious or civic activities such as serving on a school board, or as a member of or officer of a professional organization, provided such activity or organization does not compete directly with HORL. SECTION 6 CONFIDENTIAL INFORMATION 6.1 Confidentiality. During the term of and at any time after the termination of this Agreement, Officer will hold in trust and confidence and will not divulge, disclose or convey to any person, firm, corporation or other entity and will keep secret and confidential all trade secrets, proprietary information and confidential information heretofore or hereafter acquired by him concerning HORL, Head Office Reference Laboratory Ltd., or Seafield Capital Corporation, and will not use for himself or others the same in any manner, except to the extent that such information should become no longer a trade secret, proprietary or confidential.
