AND LABORATORY SPECIALISTS OF AMERICA, INC.       PAGE 12

<PAGE>

ACCU-PATH and public officials.

     8.5  NO ADVERSE CHANGE.  No material adverse change shall have occurred in

PATH operations of the Ruston, Louisiana office since December 31, 1996.

PATH Assets

     8.7  DUE DILIGENCE.  LSAI shall have performed and completed its due
diligence to verify, to its satisfaction, the existence of the Forensic Testing
Revenue Base of ACCU-PATH as represented.  Such due diligence shall be

                                   ARTICLE IX

                      ACCU-PATH'S NON-COMPETITION AGREEMENTS

     9.1  ACCU-PATH'S AGREEMENT NOT TO COMPETE.  For a period of five years
after the Closing Date, ACCU-PATH agrees that it will not directly or
indirectly: (i) engage or become interested in, whether as a partner, owner,
stockholder (other than a less than 2% interest in a corporation having
securities listed for trading on a national securities exchange), investor,
lender, provider of services, whether alone or in association with others, any
business that offers, forensic drug testing services ("Testing Services") to
any client included in the Customer Base, including without limitation Testing
Services referred by any physician associated with a client; (ii) induce or
attempt to induce any client included in the Customer Base to reduce its use of
the forensic services of LSAI.

     9.2  CONFIDENTIAL INFORMATION.  ACCU-PATH acknowledges that it has and may
continue to have access to and the use of confidential materials and
information and trade secrets concerning the ACCU-PATH Assets (including
without limitation the identity of and other information concerning clients
included in the Customer Base).  ACCU-PATH shall not use, for itself or others,
or divulge or convey to any other, except as required to fulfill the
obligations of this Agreement, any secret or confidential information,
knowledge or data related to the ACCU-PATH Assets or LSAI or to the clients or
customers, or former clients or customers, of LSAI.  Such information,
knowledge or data includes, but is not limited to, secret or confidential
matters not published or generally known in the industry, pricing information,
service requirements, sales, profits, costs or market.

     9.3  REMEDIES.  ACCU-PATH acknowledges and agrees that the provisions of
this Article IX are necessary to protect all of the ACCU-PATH Assets being
acquired by LSAI and in no way impose a significant hardship or prevents ACCU-
PATH from earning a livelihood.  In the event that this Article IX or any other
portion thereof shall be determined by any court of


ASSET PURCHASE AGREEMENT BETWEEN ACCU-PATH MEDICAL LABATORY, INC.
AND LABORATORY SPECIALISTS OF AMERICA, INC.       PAGE 13

<PAGE>

competent jurisdiction to be unenforceable by reason of its extending for too
great a period of time or over too great a range of activities, it shall be
interpreted to extend only over the maximum time period and range of
activities as to which it may be enforceable.  ACCU-PATH recognizes and
acknowledges that in the event of ACCU-PATH's failure to comply with any of
the covenants contained in this Article IX, it may be impossible to measure
in money the damages to LSAI or its successor and that in the event of such a
failure, LSAI or its successor may not have an adequate remedy at law.  It is
therefore agreed that LSAI or its successor, in addition to any other rights
or remedies which it may have, shall be entitled to immediate injunctive
relief to enforce such covenants, and that if any action or proceeding is
brought in equity to enforce the same, ACCU-PATH will not urge as a defense,
that there is an adequate remedy at law.

                              ARTICLE X

been consummated on or before February 28, 1997; or

the part of LSAI, ACCU-PATH or their respective officers, directors or
shareholders, except as stated in Section 12.8 hereof; provided, however, that
such limitation shall not apply in the event of a willful breach by LSAI or
ACCU-PATH of any of their respective material covenants contained herein in
which case the non-breaching party shall be entitled to recover from the
breaching party all out-of-pocket costs (including without limitation
reasonable attorney fees' and expenses) which the non-breaching party has

hereto hereby releases the other party at and effective as of the Closing from

hereof).

     11.2 AVAILABLE REMEDIES.  Each party expressly agrees that, consistent

to consummate the transactions contemplated hereby, subject only to the
satisfaction of conditions precedent, the remedy of specific performance shall
be available to a non-breaching and non-defaulting party to enforce performance
of this Agreement by a breaching or defaulting party, including, without
limitation, to require the consummation of the Closing.

     11.3 INDEMNITY.  (i) ACCU-PATH, in addition to the remedies accorded the
parties in Section 11.2 hereof, agrees to indemnify and hold LSAI harmless from
and against any and all claims, actions, causes of action, damages, costs and
expenses, including without limitation attorneys' fees, arising from or
relating to a breach by ACCU-PATH of the representations and warranties set
forth in Article IV, hereof.

     (ii)  LSAI, in addition to the remedies accorded the parties in Section
