ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

     On January 31, 1997, Laboratory Specialists of America, Inc. (the
"Company") acquired from Pathology Laboratories, Ltd., a Mississippi corporation
("PLL"), certain  intangible assets pursuant to an Asset Purchase Agreement
dated January 31, 1997 (the "Purchase Agreement").  PLL is a privately held
corporation.  The assets purchased included the customer list of PLL and all
contracts, contract rights and agreements, correspondence with the customers for
which PLL has provided forensic drug testing services, and all assets owned by
PLL used in connection with the PLL office in Greenville, South Carolina.

     Pursuant to the Purchase Agreement, (i) the Company paid $1,600,000 at
closing and (ii) the Company assumed the obligations of PLL under a certain
Lease between Edith Schlien and PLL, dated September 16, 1996, covering
approximately 2,500 square feet of office space located in Greenville, South
Carolina, which requires monthly base rental payments of $2083 and which expires
on September 16, 1999.  Furthermore, the Company is required make four
additional installment payments to PLL within 60 days following the end of each
three month period during the 12 months ending January 31, 1998, as follows:
(i) the first installment payment being equal to 75 percent of  Forensic Testing
Revenues (as defined below) during the first three month period ending April 30,
1997, in excess of $400,000; (ii) the second installment payment being equal to
75 percent of Forensic Testing Revenues during the six month period ending July
31, 1997, in excess of the aggregate sum of the prior installment payment and
$800,000, (iii) the third installment payment being equal to 85 percent of
Forensic Testing Revenues during the nine month period ending October 30, 1997,
in excess of the aggregate sum of the prior installment payments and $1,200,000,
and (iv) the fourth installment being equal to Forensic Testing Revenues during
the 12 month cess of the aggregate sum of the prior installment payments and
$1,600,000.  Under the Purchase Agreement, "Forensic Testing Revenues" defined
as the gross revenues during the calendar quarter or 12 month period ending
January 31, 1998, directly attributable to each customer comprising the customer
base of PLL acquired by the Company.

     Furthermore, in conjunction with the Purchase Agreement, the Company
entered into a certain Specimen Collection and Courier Service Agreement with
PLL, dated January 31, 1997, pursuant to which PLL agreed to provide specimen
collection and courier services to the Company for $5.00 per specimen collected
at designated locations and $1.25 per specimen transported by PLL to the
Company's laboratory in Belle Chasse, Louisiana.  The Specimen Collection and
Courier Service Agreement will terminate on March 1, 1997, unless sooner
terminated as a result of failure to perform the services or pay the collection
and/or courier fees, or termination by PLL of its courier routes.

     Also in conjunction with the Purchase Agreement, the Company entered into a
certain Agreement for Laboratory Testing Services with PLL, dated January 31,
1997, pursuant to which PLL will continue until February 28, 1997, to provide
forensic drug testing services to assist in the transitional consolidation and
assimilation of the customer base acquired from PLL with the drug testing
operations of the Company. For services rendered during the transition period,
PLL will retain 95 percent of the gross billings for forensic drug test, less
any contractual discounts and the direct cost of operating the Company's office
in Greenville, South Carolina. On February 28, 1997, the Company agreed to pay
PLL $150,000 as advanced compensation for services rendered by PLL. In
connection with the first installment payment under the Purchase Agreement, PLL
agreed to remit to the Company an amount equal to five percent of the net
billings for the forensic drug testing, the direct costs of operating the
Greenville, South Carolina office and the $150,000 advanced compensation
payment.

     The Company intends to consolidate and assimilate the purchased assets with
those of the Company.  In connection with the asset purchase, the Company will
continue the forensic drug testing marketing operations of PLL conducted at and
from its office in Greenville, South Carolina, and has retained certain
marketing personnel employed in such office in order to maintain PLL's market
share of forensic drug testing services.  However, there is no assurance that
the Company will be able to maintain such market share.  All forensic drug
testing operations formerly conducted and performed by PLL will be conducted and
performed at the laboratory facilities of Laboratory Specialists, Inc. in Belle
Chasse, Louisiana.  It is currently anticipated by management of the Company
that the 

                                       2
<PAGE>
 
laboratory facilities and the capacity thereof will be adequate to conduct and
perform the increased drug testing volume acquired by the Company from PLL.

     In connection with the assets purchased, because of the nature of the
assets purchased by the Company from PLL, it is anticipated that the Company
will be required to record substantially all of the purchase price of the assets
purchased as an intangible asset which will be amortized on a straight-line
basis over the estimated period that the Company will be benefitted by the
purchase of such assets.  The carrying value and recoverability of such
intangible assets will be periodically reviewed by management of the Company.
If the facts and circumstances suggest that such intangible assets may be
impaired, the carrying value of such assets will be adjusted which will result
in an immediate charge against income during the period of adjustment and/or the
length of the remaining amortization period may be shortened which will result
in an increase in the amount of amortization during the period of adjustment and
each period thereafter until fully amortized.  Once adjusted, there can be no
assurance that there will not be further adjustments for impairment and
recoverability in future periods of such intangible assets.  Of the various
factors to be considered by management of the Company in determining impairment
of such intangible assets, the most significant will be (i) the loss of all or a
portion of the forensic drug testing customer base acquired from PLL, (ii)
losses from operations, (iii) developments within the drug testing industry,
including the Company's inability to maintain its market share, development of
drug testing technologies, imposition of additional regulatory and certification
requirements, and (iv) loss or suspension for an extended period of laboratory
certification, especially by the Substance Abuse and Mental Health Services
Administration.  In the event management of the Company determines that such
intangible assets have become impaired, the adjustments for impairment and
recoverability may occur during a period of operations in which the Company has
sustained losses or has only marginal profitability from operations, and the
impairment and/or increased amortization amount will either increase such losses
from operations or reduce profitability.

          (ii)  the second installment shall be payable within 60 days following
     the end of the six-month period following closing of the Asset Purchase
     ("Six-Month Period") and shall be in an amount equal to seventy-five
     percent (75%) of Forensic Testing Revenues of the Six-Month Period in
     excess of the aggregate sum of the First Installment payment and Eight
     Hundred Thousand Dollars ($800,000.00) (the "Second Installment Payment");

          (iii) the third installment shall be payable within 60 days following
     the end of the nine-month period following Closing of the Asset Purchase
     ("Nine-Month Period") and shall be in an amount equal to eighty-five (85%)
     of Forensic Testing Revenues of the Nine-Month Period in excess of the
     aggregate sum of the First Installment Payment, the Second Installment
     Payment, and One Million Two Hundred Thousand Dollars ($1,200,000.00) (the

<PAGE>
 
     Installment Payment, One million Six Hundred Thousand Dollars
     ($1,600,000.00); provided, however, that in the event the aggregate sum of
     the First Installment Payment, the Second Installment Payment, the Third
     Installment Payment and One Million Six Hundred Thousand Dollars
     ($1,600,000.00) exceed Forensic Testing Revenues of the First Anniversary
     Period, PLL shall repay to LSAI within 60 days following the end of the
     First Anniversary Period an amount equal to the excess of the aggregate sum
     of the First Installment Payment, the Second Installment Payment, the Third
     Installment Payment and One Million Six Hundred Thousand Dollars
     ($1,600,000.00) in excess of Forensic Testing Revenues of the First
     Anniversary Period.

     Forensic Testing Revenues shall be separately accounted for by LSAI on a
customer basis so as to identify each customer and the revenues attributable to
each customer in order to further determine the Forensic Testing Revenues that
are attributable  to the customers comprising in part the Customer Base of PLL
purchased as a portion of the PLL Assets.

     Forensic Testing Revenues shall be reduced by the amount of any billing
which is uncollectible as a result of the failure to assign, or to obtain the
prior consent to any assignment by PLL of any agreement for drug testing
services between PLL and clients in the Customer Base.

          2.3  CLOSING. Subject to the terms and conditions hereof, the Closing

the PLL Assets and consummation of the transactions contemplated under this
Agreement, except with respect to the lease agreements described on Schedule
2.1.3 hereto, LSAI shall not nor shall any provision of this Agreement be
construed to cause LSAI to, assume or become liable for any liability,
obligation, performance, duty, debt, lien or any other claim of any kind or
nature of PLL, and PLL hereby acknowledges that it shall remain liable for all
of its liabilities, obligations, performances, duties, debts, liens or any other
claim of any kind or nature which arise prior to the Closing, including without
limitation the obligation of PLL to maintain any and all records and information
required to be maintained and the continuing obligation to maintain all urine
samples in a frozen state in accordance with the regulations of the Substance
Abuse and Mental Health Services Administration ("SAMHSA").

testing services ("Testing Services") to any client included in the Customer

          9.3   REMEDIES. PLL acknowledges and agrees that the provisions of
this Article IX are necessary to protect all of the PLL Assets being acquired by

period and range of activities as to which it may be enforceable. PLL recognizes
and acknowledges that in the event of PLL'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, PLL will not urge as a defense, that there is an adequate
remedy at law.
