                                   BETWEEN
                         SEAFIELD CAPITAL CORPORATION
                                     AND
                     HOME OFFICE REFERENCE LABORATORY, INC.
                 
                              SERVICES AGREEMENT

     THIS SERVICES AGREEMENT (the "Agreement") is made as of January 1, 1993,
between Seafield Capital Corporation, a Missouri corporation ("Seafield"), and
Home Office Reference Laboratory, Inc., a Delaware corporation ("HORL").

                                 INTRODUCTION

     A. Previously, Seafield (then named BMA Corporation), HORL and others were
parties to a Services Agreement, dated as of July 31, 1990 (the "Previous
Services Agreement"), pursuant to which Seafield was to provide to HORL and
HORL was to purchase from Seafield certain services.

     B. Contemporaneously, Seafield and HORL have entered into an agreement to
terminate the Previous Services Agreement, except Section 7 relating to the
Transition Agreement, and this Agreement in order to provide for the furnishing
of services to HORL in the future by Seafield, the payment of fees and certain
other matters.

     ACCORDINGLY, the parties hereto agree as follows:

SECTION 1. EFFECTIVE DATE AND TERMINATION

1.1  Term.  This Agreement shall become effective, without further action, on
January 1, 1993 (the "Effective Date"). This Agreement shall remain in effect
until December 31, 1993, and shall be renewed automatically for successive
one-year terms (January 1-December 31) until terminated in accordance with
Section 1.2.

1.2  Termination.  The obligation of Seafield to provide services pursuant to
Section 2 and the provisions of all other Sections of this Agreement other than
Section 6 shall terminate on the earlier of (a) December 31 of the then current
term of this Agreement, if 120 days or more prior thereto written notice is
given by Seafield or HORL to the other of Seafield's or HORL's intention to
terminate this Agreement, or (b) such date as the parties mutually agree to in
writing.

SECTION 2. SERVICES

2.1  Administrative Services.  Commencing on the Effective Date, and continuing
for the period provided in Section 1, Seafield agrees to make available to
HORL, to the extent HORL may require, the following services:
     (a) Seafield's corporate secretarial staff for assistance in
organizational matters associated with shareholders' meetings and meetings of
the board of directors.
     (b) Seafield's treasury staff for financial and investment advice,
including, without limitation, advice with respect to raising additional
capital, cash management, risk management and investment opportunities.
     (c) Seafield's management staff for assistance in assuring the compliance
of qualified benefit plans with relevant government regulations.

2.2  Executive and Marketing Services.  Commencing on the Effective Date, and
continuing for the period provided in Section 1, Seafield agrees to make
available to HORL, to the extent HORL may require, the services of Seafield's
senior management to provide policy advice and to attend marketing and client
development functions sponsored by HORL and others to promote HORL's laboratory
testing services (the Administrative Services described in Section 2.1 hereof
and the Executive and Marketing Services described in Section 2.2 hereof are
collectively the "Services").

2.3  Limitation on Services.  Notwithstanding anything else contained in this
Section 2:
     (a) The provisions of Sections 2.1 and 2.2 shall apply only to Services
that are reasonably required by HORL.
     (b) Seafield need not make available any Services to the extent that doing
so would unreasonably interfere with the performance of services for Seafield
by any employee of Seafield or would otherwise cause an unreasonable burden to
Seafield.

SECTION 3. COST OF SERVICES

3.1  Prices and Billing for Services.  HORL shall pay Seafield according to the
following formula:
     0.20% of sales less than $50 million, plus
     0.125% of sales of $50 million or more, but less than $100 million plus
     0.0625% of sales of $100 million or more.

The percentage fee shall be paid on or before the 45th day following the end of
each calendar quarter. In addition, HORL shall reimburse Seafield on a timely
basis for the amount of all direct travel expenses reasonably incurred by any
Seafield employee in providing Services.

3.2  Outside Professional Services.  In addition to amounts to be paid by HORL
pursuant to Section 3.1, HORL shall reimburse Seafield for the amount of all
reasonable expenses for outside professional services incurred by Seafield for
the benefit of HORL, including, without limitation, public accounting, outside
legal and outside marketing services.

SECTION 4. LIMITATION OF LIABILITY

The liability of Seafield to HORL for any loss or damage, whether direct or
indirect, arising in connection with Seafield's providing Services to HORL
pursuant to Section 2 shall not exceed the highest amount paid or payable by
HORL to Seafield for Services during any quarter in the year in which the act
or omission that caused such loss or damage occurred. IN NO EVENT WILL SEAFIELD
BE LIABLE TO HORL FOR INDIRECT, CONSEQUENTIAL OR INCIDENTAL DAMAGES, INCLUDING,
WITHOUT LIMITATION, LOSS OF PROFITS OR DAMAGE TO OR LOSS OF USE OF ANY
PROPERTY.

SECTION 5. FORCE MAJEURE

Seafield shall be excused for failure to provide the Services pursuant to
Section 2 to the extent that such failure is directly or indirectly caused by
an occurrence commonly known as force majeure, including, without limitation,
delays arising from fire, earthquake, flood or other acts of God, acts or
orders of a government, agency or instrumentality thereof, acts of a public
enemy, riots, embargoes, strikes or other concerted acts of workers (whether of
Seafield or other persons), casualties or accidents, failure or delay in
deliveries of materials or transportation, shortage of cars, trucks, fuel,
power, labor or materials, telecommunications failure or any other causes,
circumstances or contingencies, within or without the United States of America,
that are beyond the reasonable control of Seafield. Notwithstanding any events
operating to excuse the performance by Seafield, this Agreement shall continue
in full force for the remainder of its term.

SECTION 6. CONFIDENTIALITY

Except as otherwise required under applicable law, Seafield and HORL agree to
maintain as confidential and not to disclose to any third party any and all
information provided by one party to another or otherwise obtained by one party
from another party in the performance of this Agreement. The provisions of this
Section 6 shall survive the termination of this Agreement.

SECTION 7. ENFORCEMENT

HORL and Seafield acknowledge and agree that a remedy at law for any breach of
Section 6 hereof would be inadequate, and each agrees and consents that
temporary and permanent injunctive relief may be granted in any proceeding
which may be brought to enforce any provisions of such Section 6 hereof without
the necessity of proof of actual damage. If the scope of any restriction
contained in Section 6 hereof is too broad to permit enforcement of such
restriction to its full extent, then such restriction shall be enforced to the
maximum extent permitted by law, and HORL and Seafield each agrees and consents
that such scope may be judicially modified accordingly in any proceeding
brought to enforce such restrictions.

SECTION 8. MISCELLANEOUS

8.2  Governing Law.  The validity, interpretation, enforceability and
performance of this Agreement shall be governed by, and construed and enforced
in accordance with, the laws of the State of Missouri.

8.3  Entire Agreement.  The parties intend that the terms of this Agreement
shall be the final expression of their agreement with respect to the subject
matter hereof and may not be contradicted by evidence of any prior or
contemporaneous agreement. The parties further intend that this Agreement shall
constitute the complete and exclusive statement of its terms and that no
extrinsic evidence whatsoever may be introduced in any judicial, administrative

agreement between the parties with respect to the subject matter hereof and
supersedes all prior negotiations, undertakings, representations and
agreements, if any, of the parties hereto.

8.4  Amendment and Waivers.  This Agreement may not be amended except upon the
written consent of the parties hereto. By an instrument in writing, either
party may waive compliance by the other party with any term or provision of
this Agreement that such other party was or is obligated to comply with or
perform; provided, however, that such waiver shall not operate as a waiver of,
or estoppel with respect to, any other or subsequent failure. No failure to
exercise and no delay in exercising any right, remedy or power hereunder shall
operate as a waiver thereof. No partial exercise of any right, remedy or power
hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, remedy or power provided herein or by law or in equity.

8.5  Severability.  If any provision of this Agreement, or the application
thereof to any person, place or circumstance, shall be held by a court of

this Agreement and such provisions as applied to other persons, places and
circumstances shall remain in full force and effect.

8.6  Counterparts.  This Agreement may be executed in counterparts, each of
which shall constitute one and the same instrument.

8.7  Interpretation of Agreement.  The section and other headings used in this
Agreement are for reference purposes only and shall not constitute a part
hereof or affect the meaning or interpretation of this Agreement. The term
"person" shall include any individual, partnership, joint venture, corporation,
trust, unincorporated organization, any other business entity and any
government or any department or agency thereof, whether acting in an
individual, fiduciary or other capacity. Whenever the context so requires, the
use of the singular shall be deemed to include the plural and vice versa.

8.8  Further Assurances.  Subject to the terms and conditions hereof, each
party agrees to use its best efforts to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate the transactions contemplated by this Agreement as expeditiously as
practicable, including, without limitations, the performance of such further
acts or the execution and delivery of any additional instruments or documents
as any party may reasonably request in order to carry out the purposes of this
Agreement and the transactions contemplated hereby.
