                          NOTES TO FINANCIAL STATEMENTS

         (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1997, AND 
                       SEPTEMBER 30, 1998, IS UNAUDITED.)

1.  GENERAL

The consolidated financial statements included in this report have been 
prepared by the Company pursuant to the rules and regulations of the 
Securities and Exchange Commission for interim reporting and include all 
adjustments which are, in the opinion of management, necessary for a fair 
presentation. These financial statements have not been audited by an 
independent accountant. The consolidated balance sheet at December 31, 1997, 
has been derived from the audited balance sheet of the Company.

Certain information and footnote disclosures normally included in financial 
statements prepared in accordance with generally accepted accounting 
principles have been condensed or omitted pursuant to such rules and 
regulations for interim reporting. The Company believes that the disclosures 
are adequate to make the information presented not misleading. However, these 
financial statements should be read in conjunction with the audited financial 
statements and notes thereto included in the Annual Report on Form 10-KSB 
filed by the Company with the Securities and Exchange Commission on March 27, 
1998. The financial data for the interim periods presented may not 
necessarily reflect the results to be expected for the full year.

2.  EARNINGS PER COMMON SHARE

Both basic and diluted earnings per common share were computed using the 
weighted average number of common shares outstanding. Diluted earnings per 
share also reflect the dilutive effect, if any, of the conversion of stock 
options (with the exception of the 525,000 stock options issued on July 20, 
1998 and rescinded effective with the date of grant), outstanding warrants 
and contingent shares. In the diluted earnings per share calculation the 
outstanding warrants were calculated using the weighted average market price 
during the term of the warrants.

Income from continuing operations for purposes of computing both basic 
earnings per share and diluted earnings per share was $486,419 and $460,969 
for the three months ended September 30, 1998 and 1997, respectively, and 
$1,440,725 and $1,083,585 for the nine months ended September 30, 1998 and 
1997, respectively. A reconciliation of the average shares outstanding used 
to compute basic earnings per share to the shares used to compute diluted 
earnings per share for both periods is presented below:

3.  GOODWILL AND CUSTOMER LIST

Goodwill and customer lists are being amortized on a straight-line basis over 
twenty to forty years and fifteen years, respectively. The Company 
continually evaluates whether events and circumstances have occurred that 
indicate the remaining estimated useful life of goodwill and customer lists 
may warrant revision or that the remaining unamortized balance of goodwill or 
customer lists may not be recoverable. When factors, such as operating 
losses, loss of customers, loss or suspension for an extended period of 
laboratory certification, or changes in the drug testing industry, if 
present, indicate that goodwill or customer lists should be evaluated for 
possible impairment, the Company uses an estimate of the related undiscounted 
cash flows over the remaining life of the goodwill or customer lists in 
measuring whether the goodwill and the customer lists are recoverable. 
Although management believes that goodwill and the customer lists are 
currently recoverable over the respective remaining amortization periods, it 
is possible, due to a change in circumstances, that the carrying value could 
become impaired in the future. Such impairment could have a material effect 
on the results of operations in a particular reporting period.

4.  CONTINGENT LIABILITIES

Incidental to its business, the Company from time to time is sued by 
individuals who have tested positive for drugs of abuse or who allege that 
improper analysis has been performed, generally arising from Laboratory 
Specialists, Inc.'s, the company's wholly owned subsidiary ("LSI"), alleged 
failure to properly administer drug urinalysis tests. LSI is currently a 
defendant in several such lawsuits. Based upon prior successful defense of 
similar-type lawsuits, the Company believes it has valid defenses to each of 
such lawsuits, and intends to vigorously defend in such actions. Although LSI 
maintains insurance to protect itself against such liability, and LSI's 
insurance carriers have assumed the defense of LSI in connection with certain 
actions, the extent of such insurance coverage is limited, both in terms of 
types of risks covered by the policies and the amount of coverage. In the 
opinion of the Company's management and it's legal counsel, these suits and 
claims should not result in judgments or settlements which would have a 
material adverse effect on the Company's results of operations or financial 
position. Although LSI has not experienced any material liability related to 
such claims, there can be no assurance that LSI, and possibly LSAI, will not 
at some time in the future experience significant liability in connection 
with such claims and such liability may exceed the extent of such insurance 
coverage, both in terms of risks covered by the policies and the amount of 
coverage, which could have a material adverse effect upon the results of 
operations and financial condition of the Company.

5.  SUPPLEMENTAL SCHEDULE OF NON-CASH INVESTING AND FINANCING ACTIVITIES

In connection with the purchase of assets from Pathology Laboratories, Ltd. 
("PLL"), a liability of $960,000 was recorded based upon estimated future 
quarterly installment payments to be made to PLL. As of September 30, 1998, 
all installment payments, totaling $751,688 had been made and the remaining 
balance of the liability of $208,312, was treated as a reduction in the 
carrying value of the PLL customer list since it will not be paid pursuant to 
the purchase agreement.

In connection with the purchase of assets from Accu-Path Medical Laboratory, 
Inc. ("Accu-Path"), a liability of $260,000 was recorded based upon estimated 
future quarterly installment payments to be made to Accu-Path. As of 
September 30, 1998, the first three installment payments, totaling 
approximately $136,606, had been made, with one quarterly installment payment 
remaining to be paid.

In connection with the purchase of assets from Harrison Laboratories, Inc. 
("HLI"), a liability of $460,000 was recorded based upon the estimated future 
payment obligation. As of September 30, 1998, no payments have been made on 
this liability; however, a $33,855 reduction was recorded as a result of the 
offset of amounts owed to Laboratoary Specialists, Inc. by HLI.

                                -8-

The above transactions, except the reductions in the liabilities owed to PLL, 
Accu-Path and HLI, are non-cash transactions and have been excluded from the 
accompanying statements of cash flows.

6.  SUBSEQUENT EVENTS

On October 15, 1998, the Company issued 1,500 shares of common stock to James 
Cassel in connection with the exercise of certain warrants.

The Company rescinded 525,000 stock options that had been issued on July 20, 
1998, effective with the date of grant.

On October 21, 1998, the Company entered into a definitive agreement to be 
acquired by The Kroll-O'Gara Company (NASDAQ : KROG) for a purchase price of 
approximately $5 per share, subject to certain conditions and payable in 
Kroll-O'Gara common stock. Closing of the transaction is anticipated in 
December, 1998 and is subject to the approval of the shareholders of the 
Company.

On October 23, 1998, the Company issued 15,373 shares of common stock to 
James Cassel in connection with the exercise of certain warrants.

    Laboratory Specialists of America, Inc. (the "Company" or "LSAI"), an 
Oklahoma corporation, was organized in March 1994. Effective July 8, 1994, 
and January 2, 1996, respectively, LSAI acquired all of the capital stock of 
Laboratory Specialists, Inc. ("LSI"), a Louisiana corporation, and National 
Psychopharmacology Laboratory, Inc. ("NPLI"), a Tennessee corporation, and 
LSI and NPLI became wholly owned subsidiaries of LSAI.

    On January 31, 1997, the Company acquired from Pathology Laboratories, 
Ltd.("PLL"), certain forensic drug testing assets (the "PLL Asset Purchase") 
pursuant to an Asset Purchase Agreement, dated January 31, 1997 (the "PLL 
Purchase Agreement"). The assets purchased included the customer list of PLL 
and all related assets, and all assets owned by PLL used in connection with 
the PLL office in Greenville, South Carolina. Pursuant to the PLL Purchase 
Agreement, the Company (i) paid $1,600,000 at closing and $765,601 in four 
quarterly installments during the 12-month period ended January 31, 1998, and 
(ii) 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 $2,083 and which expires on 
September 16, 1999.

    On December 1, 1997, the Company acquired from Accu-Path Medical 
Laboratory, Inc. ("Accu-Path") certain intangible assets pursuant to an Asset 
Purchase Agreement, dated December 1, 1997 (the "Accu-Path Asset Purchase"). 
Pursuant to the Asset Purchase Agreement, the Company agreed to pay 180 
percent of the forensic testing revenues during the period from June through 
November, 1998 as follows: (i) $100,000 paid at closing, (ii) an amount equal 
to 50 percent of the forensic testing revenues for each of the first three 
quarters, to be paid 30 days following the end of each quarter, and (iii) the 
balance to be paid in four quarterly installments with the first payment due 
30 days following the end of the first 12 month anniversary period from the 
date of closing. The estimated gross revenues attributable to this customer 
base was approximately $360,000. As of September 30, 1998, the first three 
installment payments, totaling approximately $136,606, had been made to 
Accu-Path and one installment remains to be paid.

    On May 1, 1998, the Company acquired from Harrison Laboratories, Inc. 
("HLI") a customer list pursuant to an Asset Purchase Agreement, dated April 
13, 1998 (the "HLI Asset Purchase"). In connection with the HLI Asset 
Purchase, the Company (i) paid $500,000 at closing and agreed to pay on or 
before May 30, 1999, an amount equal to the revenues attributable to the 
customer list during the one-year period ending April 30, 1999, in excess of 
$500,000, (ii) assumed HLI's

                                       -9-
<PAGE>

obligations under a five-year lease with Linc Quantum Analytics, Inc., dated 
November 11, 1997, and acquired the related equipment, and (iii) entered into 
a three-year employment agreement with the principal shareholder of HLI as a 
sales representative, providing for a base salary of $50,000 per year, 
monthly bonuses equal to 3.5 percent of revenues attributable to the customer 
list, and other benefits. The purchase price of the customer list was 
recorded as an intangible asset, which is being amortized over 15 years.

    On June 4, 1998, LSAI completed the offering of 555,222 shares of Common 
Stock for net proceeds of $2,312,647 (the "1998 Private Offering"). 
Furthermore, LSAI paid Jesup & Lamont Securities Corporation ("Jesup & 
Lamont") a placement fee of $174,650 and issued 55,522 warrants to Jesup & 
Lamont and its designees (the "Jesup & Lamont Group Warrants"). In connection 
with the 1998 Private Offering, LSAI agreed to file a registration statement 
under the 1933 Act with respect to the Common Stock offered and underlying 
the Jesup & Lamont Group Warrants and maintain the effectiveness of the 
registration statement for a minimum of six years. Pursuant to such 
agreement, LSAI filed the registration statement on July 2, 1998, which 
became effective September 2, 1998.

    On July 1, 1998, the Company acquired from Toxworx Laboratories, Inc. 
("TLI"), a California corporation, a customer list pursuant to an Asset 
Purchase Agreement, dated June 8, 1998, ("TLI Asset Purchase"). In connection 
with the TLI Asset Purchase, the Company paid $2,400,000 at closing. The 
purchase price of the customer list was recorded as an intangible asset, 
which is being amortized over 15 years.

    Through LSI, the Company operates an independent forensic drug testing 
laboratory providing integrated drug testing services to corporations and 
governmental bodies, by negotiated contract, for detection of illegal drug 
use by employees and prospective employees. The Company's customers are 
primarily in the construction, transportation, service, mining, and 
manufacturing industries, principally located in the southeast and southwest 
United States.

</TABLE>

    During the three and nine months ended September 30, 1998, LSI 
experienced a 1.1 percent and 2.4 percent decrease in the price per specimen, 
compared to the three and nine months ended September 30, 1997, principally 
due to increased price competition amongst providers of drug testing 
services, price per specimen being an important factor in obtaining

                                      -10-
<PAGE>

and maintaining clients. Management of LSI closely monitors its price per 
specimen, the prices of its competitors and the costs of processing specimens 
to remain competitive, as well as profitable. There can be no assurance that 
price per specimen will not decline during 1998. In the event price 
stabilization does not occur, LSI will, as it has in the past, take 
appropriate measures to downsize its drug testing personnel and possibly 
further automate the testing process and employ additional technology to 
continue profitability, although there can be no assurance that such measures 
will assure profitability in the event of substantial price reductions within 
the short term.

COMPARISON OF THREE-MONTH AND NINE-MONTH PERIODS ENDED SEPTEMBER 30, 1997 AND 
1998

    Revenues increased to $12,039,154 in the nine months ended September 30, 
1998 (the "1998 Interim Period"), from $9,549,032 in the nine months ended 
September 30, 1997 (the "1997 Interim Period"), an increase of 26.1 percent. 
Revenues increased to $4,379,390 in the three months ended September 30, 1998 
(the "1998 Third Quarter"), from $3,538,050 in the three months ended 
September 30, 1997 (the "1997 Third Quarter"), an increase of 23.8 percent. 
The increase in revenues was due to a 30.2 percent and 28.6 percent increase, 
respectively, in the number of specimens analyzed during the 1998 Interim 
Period as compared to the 1997 Interim Period and the 1998 Third Quarter as 
compared to the 1997 Third Quarter, although partially offset by a decrease 
of 2.4 percent and 1.1 percent, respectively, in the average price per 
specimen. The increase in number of specimens analyzed was attributable to 
the Accu-Path, HLI, and TLI Asset Purchases as well as LSI's normal sales and 
marketing efforts. The decrease in the average price per specimen was 
principally due to increased price competition among providers of drug 
testing services, price per specimen being an important factor in obtaining 
and maintaining clients.

    Cost of revenues increased $1,192,239 from $4,246,113 in the 1997 Interim 
Period to $5,438,352 in 1998 Interim Period and $389,250 from $1,586,256 in 
the 1997 Third Quarter to $1,975,506 in the 1998 Third Quarter, increases of 
28.1 percent and 24.5 percent, respectively. Gross profit on revenues 
decreased as a percentage of revenues from 55.5 percent in the 1997 Interim 
Period to 54.8 percent in 1998 Interim Period and from 55.2 percent in the 
1997 Third Quarter to 54.9 percent in the 1998 Third Quarter. The decrease 
was primarily due to the decrease in the price per specimen.

    Operating expenses increased from $3,331,186 in the 1997 Interim Period 
to $4,184,265 in the 1998 Interim Period and from $1,122,839 in the 1997 
Third Quarter to $1,580,373 in the 1998 Third Quarter, increases of 25.6 
percent and 40.7 percent respectively, but decreased as a percentage of 
revenues from 34.9 percent to 34.7 percent in the Interim Period, and 
increased as a percentage of revenues from 31.7 percent to 36.1 percent in 
the Third Quarter . The increase in operating expenses was attributable to 
the increase in selling expenses of $262,398 for the Interim Period and 
$129,561 for the Third Quarter, general and administrative expenses of 
$440,146 for the Interim Period and $253,174 for the Third Quarter and 
depreciation and amortization of $150,535 for the Interim Period and $74,799 
for the Third Quarter. The increase in general and administrative expenses 
was principally the result of (i) an increase in executive officer 
compensation, (ii) the addition of several key positions at LSI and (iii) the 
addition of certain overhead costs associated with the PLL, Accu-Path, HLI 
and TLI Asset Purchases. The increase in selling expenses was due to several 
additions to the sales force during late 1997 and early 1998, to assist in 
maintaining forensic clients acquired as part of the PLL, Accu-Path, HLI and 
TLI Asset Purchases, as well as additional business development in other 
areas of the United States. Depreciation increased due to the renovation of 
the new laboratory and purchase of additional equipment at LSI, while 
amortization increased due to the customer list acquisitions from PLL, 
Accu-Path, HLI and TLI and the amortization of the purchase price of such 
customer lists.

    Income from operations increased from $1,971,733 in the 1997 Interim 
Period to $2,416,537 in the 1998 Interim Period, a 22.6 percent increase, but 
decreased from $828,955 in the 1997 Third Quarter to $823,511 in the 1998 
Third Quarter, a 0.7 percent decrease. Operating income decreased as a 
percentage of revenues from 20.6 percent to 20.1 percent in the Interim 
Period and from 23.5 percent to 18.8 percent in the Third Quarter.

    Interest expense decreased 2.9 percent from $152,467 in the 1997 Interim 
Period to $147,993 in 1998 Interim Period and 20.1 percent from 61,983 in the 
1997 Third Quarter to $49,555 in the 1998 Third Quarter. The decrease in 
interest expense was due in part to the repayment in full of the note payable 
to Mbf USA, Inc. during the first quarter of 1998 as well as

                                      -11-
<PAGE>

the gradual reduction in the monthly interest expense related to the bank 
loans acquired during 1997 associated with the PLL Asset Purchase and the 
purchase and renovation of the new laboratory building. Interest income 
increased from $37,112 in the 1997 Interim Period to $106,636 in the 1998 
Interim Period, a 187.3 percent increase, and from $17,619 in the 1997 Third 
Quarter to $28,813 in the 1998 Third Quarter, a 63.5 percent increase. These 
increases were due to additional funds on deposit primarily from the exercise 
of stock warrants late in 1997 and the 1998 Private Offering during the 
second quarter of 1998. Other income increased from $1,130 in the 1997 
Interim Period to $77,055 in the 1998 Interim Period and from $1,058 in the 
1997 Third Quarter to $24,568 in the 1998 Third Quarter. The increase in 
other income is primarily due to a one-time gain realized due to the early 
payout of the note payable to MBf USA, Inc. in addition to the recovery of 
bad debts previously written off. Net income, after provision for income 
taxes, increased from $1,083,585 in the 1997 Interim Period to $1,440,725 in 
the 1998 Interim Period, a 33.0 percent increase, and from $460,969 in the 
1997 Third Quarter to $486,419 in the 1998 Third Quarter, a 5.5 percent 
increase.

QUARTERLY RESULTS OF OPERATIONS

    LSI's operations are affected by seasonal trends to which drug testing 
laboratories are generally subject. In LSI's experience, testing volume tends 
to be higher in the second calendar quarter and lower in the winter holiday 
season and the beginning of the first calendar quarter primarily due to 
hiring patterns which affect pre-employment drug testing. Because the general 
and administrative expenses associated with maintaining and adding to the 
testing work force are relatively fixed over the short term, margins tend to 
increase in periods of higher testing volume and decrease in periods of lower 
testing volume. These effects are not always apparent because of the impact 
and timing of the startup of new businesses and other factors such as the 
timing and amount of price increases or decreases. Nevertheless, the results 
of operations for a particular quarter may not be indicative of the results 
to be expected during other quarters.

    INCOME TAXES

    Income taxes accrued for the nine months ended September 30, 1998, were 
based on an effective combined federal and state corporate income tax rate of 
approximately 40 percent of pretax income.

LIQUIDITY AND CAPITAL RESOURCES

    Net cash provided by operating activities totaled $1,858,689 in the nine 
months ended September 30, 1998, and $1,596,727 in the nine months ended 
September 30, 1997. As of September 30, 1998, LSAI had working capital of 
$3,058,193, compared to working capital of $3,305,983, at December 31, 1997.

    On August 25, 1998, LSI entered into a revolving line of credit loan 
agreement with Hibernia National Bank (the "Bank"), which will mature on 
August 25, 2000, under which LSI may draw up to $1,000,000 (the "Revolving 
Loan"). As of September 30, 1998, there were no borrowings outstanding under 
the Revolving Loan. It is anticipated that any advances on the Revolving Loan 
will be based upon LSI's liquid assets including its accounts receivable. 
Amounts drawn under the Revolving Loan bear interest at Citibank, N.A. rate. 
The Revolving Loan is secured by the accounts receivable, intangible assets, 
and by a mortgage on the building owned by LSI, and is guaranteed by LSAI. 
The loan agreement contains various covenants, including certain financial 
ratios.

FUTURE OPERATIONS AND LIQUIDITY

    On January 9, 1997, LSI entered into a loan agreement with Hibernia 
National Bank (the "bank") for a term loan of $1,700,000 to be used to fund 
the PLL Asset Purchase. This loan is payable in 59 monthly principal 
installments of approximately $28,333, with a final principal payment 
becoming due on January 10, 2002, of approximately $28,547. The outstanding 
principal balance of this loan bears interest at the Citibank N.A. Rate. As 
of September 30, 1998, the interest rate was 9 percent per annum and the 
outstanding principal amount of such loan was approximately $1,133,333.

    On July 2, 1997, LSI entered into a loan agreement with the bank for a 
term loan in the principal amount of $720,000,

                                      -12-
<PAGE>

to refinance the building to which LSI's laboratory has been relocated. This 
loan is payable in 36 monthly installments of approximately $9,800, followed 
by 23 monthly installments of approximately $6,000, with a final payment 
becoming due on July 2, 2002, of approximately $484,700. The outstanding 
principal balance of this loan bears interest at a rate of 8.65 percent per 
annum. As of September 30, 1998, the outstanding principal balance amount of 
such loan was approximately $653,443.

    On December 1, 1997, the Company completed the Accu-Path Asset Purchase 
and pursuant thereto agreed to pay 180 percent of the forensic testing 
revenues during the period from June through November, 1998 as follows: (i) 
$100,000 paid at closing, (ii) an amount equal to 50 percent of the forensic 
testing revenues for each of the first three quarters, to be paid 30 days 
following the end of each quarter, and (iii) the balance to be paid in four 
quarterly installments with the first payment due December 31, 1998. The 
estimated gross revenues attributable to this customer base was approximately 
$360,000. As of September 30, 1998, total payments of $136,606 have been 
recorded as reductions in the liability owed to Accu-Path for the first three 
quarterly installments.

    On May 1, 1998, the Company completed the HLI Asset Purchase and pursuant 
thereto (i) paid $500,000 at closing, (ii) assumed the obligations of HLI 
under a certain lease, dated November 11, 1997, which requires 60 monthly 
base payments of $6,137, and (iii) is required to make a final payment, on or 
before, May 30, 1999, in an amount equal to 100 percent of the gross revenues 
directly attributable to each customer comprising the customer base of HLI 
for the year ended April 30, 1999, exceeding $533,855. The estimated gross 
revenues attributable to the customer base, for the year ended December 31, 
1997, was approximately $960,000. As of September 30, 1998, no cash payments 
have been made toward the liability owed to Harrison, but a reduction has 
been recorded in the amount of $33,855 for amounts owed to LSI by HLI and 
offset against the amount due.

    On June 26, 1998, 480,000 stock options were exercised by officers of the 
Company. Pursuant to the stock option plan, the exercise price of the stock 
options and the payroll taxes associated with the exercise of the stock 
options were paid to the Company in the form of previously issued fully 
mature shares of Common Stock of the Company. As a result of the transaction, 
105,906 additional shares of Common Stock were issued on June 26, 1998, and 
the Company paid approximately $478,962 in related payroll taxes on July 16, 
1998. The payroll taxes had been accrued as part of the payroll tax liability 
on the balance sheet as of June 30, 1998.

    On July 1, 1998, the Company acquired from Toxworx Laboratories, Inc. 
("TLI"), a California corporation, a customer list pursuant to an Asset 
Purchase Agreement dated June 8, 1998, ("TLI Asset Purchase"). In connection 
with the TLI Asset Purchase, the Company paid $2,400,000 at closing. The 
purchase price of the customer list was recorded as an intangible asset, 
which is being amortized over 15 years.

    FUTURE ASSESSMENT OF RECOVERABILITY AND IMPAIRMENT OF GOODWILL. The 
carrying value and recoverability of unamortized goodwill and customer lists 
will be periodically reviewed by management of the Company. If the facts and 
circumstances suggest that the goodwill or customer lists may be impaired, 
the carrying value of goodwill or customer lists will be adjusted which will 
result in an immediate charge against income during the period of the 
adjustment and/or the length of the remaining amortization period may be 
shortened which will result in an increase in the amount of goodwill or 
customer list 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. In the event management of the Company determines that 
goodwill or the customer list has become impaired, the adjustment for 
impairment and recoverability will most likely 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 
further reduce profitability.

    YEAR 2000 COMPUTER SYSTEM COMPLIANCE. The Company has two primary 
computer systems both of which were developed employing six digit date 
structures. Where date logic requires the year 2000 or beyond, such 
structures may produce inaccurate results. Management has substantially 
completed the implementation of a program to comply with year 2000 
requirements on a system-by-system basis including information technology 
("IT") and non-IT systems (e.g.

                                      -13-
<PAGE>

microcontrollers). Management expects the program to be complete during 1998 
at which time the Company's computer systems are expected to be year 2000 
compliant.

    Management has evaluated its in-house supported IT systems and found no 
instances of date dependent calculations or operations that are affected by 
this six digit date structure. The Company's vendor-supported IT system has 
been updated and certified year 2000 compliant by the vendor. Non-IT systems 
including all personal computers will be evaluated by a third party 
contractor, updated if necessary, and certified as compliant during 1998. The 
Company's risks associated with the year 2000 are mainly its ability to 
communicate with its distributors, take orders for and ship products and pay 
its employees, distributors and vendors. Although management's evaluation is 
complete and vendor certifications are being obtained, a failure of the 
Company's computer systems or other support systems to function adequately 
with respect to the year 2000 issues could have a material effect on the 
Company's operations. Based on progress to date, there is no need for a 
contingency plan and such a plan has not been developed. The Company 
estimates that the total cost of its program to make the Company's computer 
system year 2000 compliant is less than $25,000.

    The Company is in the early process of contacting its major suppliers to 
determine if their systems will be year 2000 compliant on a timely basis. In 
the event that the Company experiences product unavailability or supply 
interruptions due to year 2000 non-compliance by its suppliers, management 
believes that it would be able to obtain alternative sources of its products. 
A significant delay or reduction in availability of products, however, could 
also have a material adverse effect on the Company's operations.

PART II-OTHER INFORMATION

    ITEM 1.       LEGAL PROCEEDINGS

    Other than the pending litigation previously reported in the Annual 
Report on Form 10-KSB filed with the Commission on March 27, 1998, LSAI does 
not have any pending litigation. In the ordinary course of its business, LSI 
from time to time is sued by individuals who have tested positive for drugs 
of abuse. To date, LSI has not experienced any material liability related to 
these claims, although there can be no assurance that LSI will not at some 
time in the future experience significant liability in connection with such 
claims. Based upon the prior successful defense of similar-type litigation, 
LSI believes they have valid defenses to the plaintiffs claims in all pending 
litigation, and LSI intends to vigorously defend themselves in such 
litigation. LSI is not currently a defendant party in any other legal 
proceedings other than routine litigation that is incidental to the business 
of LSI, and management of LSI believes the outcome of such legal proceedings 
will not have a material adverse effect upon the results of operations or 
financial condition of LSI . Furthermore, management of LSI believes that the 
liability coverage is adequate with respect to the pending litigation and, in 
general, for the business of LSI .

misleading in any material respect.

     (d)  Receivership.  If an order, judgment or decree shall be entered by

     (e)  Insolvency.  If the Borrower or any Guarantor shall: (i) apply for,

                                     -31-
<PAGE>

     SECTION 8.02. Remedies.

          If an Event of Default should occur, Lender, without notice to 
Borrower, shall have no obligation to make any further Advance hereunder.  If 
such default is not cured within ten (10) Business Days from the date of 
giving of Lender's notice to Borrower ("Default After Notice"), then Lender 
shall have the right to immediately declare the Note, the Indebtedness and 
all amounts secured to be immediately due and payable, whereupon the same 
shall be immediately due and payable without presentment, demand, protest, or 
notice of any kind (all of which are hereby expressly waived by Borrower), 
and Lender may thereupon institute proceedings to collect the same, including 
the right to institute foreclosure and/or enforcement proceedings on the Loan 
Documents, or any of them.  However, if the Event of Default is other than an 
obligation of Borrower to pay money, then before a Default After Notice shall 
have occurred, Borrower shall have thirty (30) days from the date of delivery 
of Lender's notice to Borrower within which to cure it, and if the Event of 
Default cannot be reasonably cured within such thirty (30) day period, and if 
Borrower commences the action required to cure such default and diligently 
pursues such action, then the period shall be extended for such time as may 
be required in the sole judgment of Lender to cure such default.  In addition 
to all other rights and remedies available to Lender hereunder, Lender shall 
have all rights and remedies available under the law against any person or 
persons for damages or other compensation or remuneration that may be owed to 
Lender on account of the violation, default, or breach of any covenant, 
obligation, warranty, provision, clause or representation in Lender's favor.

                                  ARTICLE IX
                                       
                              GENERAL PROVISIONS

     Throughout the term of this Agreement:

     SECTION 9.01. Cumulative Rights.  The rights and remedies of Lender 
under this Agreement, the Note, and the other Loan Documents shall be 
cumulative, and the exercise or partial exercise of any such right or remedy 
shall not preclude the exercise of any other right or remedy.

     SECTION 9.02. Approval by Lender.  All proceedings relating to the Loan 
and all documents required or contemplated by this Agreement, and the persons 
responsible for the execution and preparation thereof, shall be satisfactory 
to Lender, and Lender's counsel shall have received copies (or certified 
copies where appropriate in such counsel's judgment) of all documents 
requested.

     SECTION 9.03. No Waiver.  No Advance shall constitute a waiver of any of 
the conditions to Lender's obligation to make further Advances.  If Borrower 
is unable to satisfy any such condition, no Advance or waiver shall have the 
effect of precluding Lender from thereafter declaring an Event of Default 
because any such condition shall remain unsatisfied.

     SECTION 9.04. Facts.  Any condition of this Agreement which requires the 
submission of evidence of the existence or non-existence of a specified fact 
or facts implies as a condition the 

                                     -32-
<PAGE>

existence or non-existence, as the case may be, of such fact or facts, and 
Lender shall, at all times, be free independently to establish to its 
reasonable satisfaction such existence or non-existence.

     SECTION 9.05. Third Party Beneficiaries.  All conditions and obligations 
of Lender to make Advances hereunder are imposed solely and exclusively for 
the benefit of Lender and its assigns.  No other person shall have standing 
to require satisfaction of such conditions or be entitled to assume that 
Lender will refuse to make Advances in the absence of strict compliance with 
any or all thereof, and no other person shall, under any circumstances, be 
deemed to be a beneficiary of such conditions, any or all of which may be 
freely waived, in whole or in part, by Lender at any time in its sole 
discretion.

     SECTION 9.06. Notices.  All notices required hereunder shall be in 
writing and shall be deemed to have been given (i) when delivered or (ii) if 
delivery is refused, then on the date of attempted delivery, by the United 
States mail by certified or registered mail, return receipt requested, or by 
commercial overnight courier service, addressed to any party hereof at its

     SECTION 9.09. Entire Agreement.  This Agreement sets forth the entire 
agreement of the Lender and the Borrower, and the Guarantor with respect to 
the Loan, and supersedes all prior written or oral understandings with 
respect thereto; provided, however, that all written representations,

consents to Lender's sale or transfer, whether now or later, of one or more

related or unrelated to Lender.  Lender may provide, without any limitation 
whatsoever, to any one or more purchasers, or potential purchasers, any 
information or knowledge Lender may have about Borrower or about any other 
matter relating to the Loan, and Borrower hereby waives any rights to privacy 
it may have with respect to such matters and specifically consents to the 
release of such information.  Borrower additionally waives any and all 
notices of sale of participation interests, as well as all notices of any 
repurchase of such participation interests.  Borrower also agrees that the 
purchasers of any such participation interest will be considered as the 
absolute owners of such interest in the Loan and will have all the rights 
granted under the participation agreement or agreements governing the sale of 
such participation interests.  Borrower further waives all rights of offset 
or counterclaim that it may have now or later against Lender or against any 
purchaser of such participation interests and unconditionally agrees that 
either Lender or such purchaser may enforce Borrower's obligation under the 
Loan irrespective of the failure or insolvency of any holder of any interest 
in the Loan.  Borrower further agrees that the purchaser of any such 
participation interests may enforce its interest irrespective of any personal 
claims or defenses that Borrower may have against Lender.

     SECTION 9.13. Non-Waiver of Rights.  Neither failure nor delay of Lender 
to exercise any right, power or privilege under this Agreement shall operate 
as a waiver thereof.  The single or partial exercise by Lender of any right,

right, power or privilege hereunder.

     SECTION 9.14. Governing Law.  This Agreement and all aspects of the Loan 
shall be governed by laws of the State of Louisiana.

     SECTION 9.15. Intervention by Guarantors.  Each Guarantor intervenes in

made by the Lender or on its behalf.  All statements in any such certificate 
or other instrument shall constitute warranties and representations by 
Borrower and Guarantor hereunder.

     SECTION 9.18. Separate Covenants.  Each covenant contained in this 
Agreement shall be construed (absent an express contrary provision therein) 
as being independent of each other covenant contained herein and compliance 
with any one covenant shall not (absent such an express contrary provision) 
be deemed to excuse compliance with any or all other covenants.

     SECTION 9.19. Severability.  If any provision or the application of any 
provision of this Agreement shall to any extent be invalid or unenforceable, 
then the remainder of this Agreement or the application of such provision in

unenforceable) shall not be affected, and each provision of this Agreement 
shall be valid and enforceable to the fullest extent permitted by law.      

     SECTION 9.20. Limitation of Liability.  This Agreement, the Note, and 
the other Loan Documents, are executed by an officer of Lender, and by 
acceptance of the Loan, Borrower agrees that for the payment of any claim or 
the performance of any obligations hereunder resulting from any default by 
Lender, resort shall be had solely to the assets and property of Lender, and 
no shareholder, officer, employee or agent of Lender shall be personally 
liable therefor.

     SECTION 9.21. Multiple Parties.  All of the covenants, agreements, and 
obligations undertaken by Borrower shall bind each of the persons comprising 
Borrower, in solids.

     (g)  Any election of remedies by Lender that may destroy or impair

Guarantor warrants and agrees that each of the waivers set forth above is 
made with Guarantor's full knowledge of its significance and consequences, 
and that, under the circumstances, such waivers are reasonable and not 
contrary to public policy or law.  If any such waiver is determined to be 
contrary to any applicable law or public policy, such waiver shall be 
effective only to the extent permitted by law.

GUARANTOR'S SUBORDINATION OF RIGHTS. in the event that Guarantor should for 
any reason (a) advance or lend monies to Borrower, whether or not such funds 
are used by Borrower to make payment(s) under Borrower's Indebtedness, and/or 
(b) make any payment(s) to Lender or others for and on behalf of Borrower 
under Borrower's Indebtedness, and/or (c) make any payment to Lender in total 
or partial satisfaction of Guarantor's obligations and liabilities under this 
Agreement, and/or (d) if any of Guarantor's property is used to pay or 
satisfy any of Borrower's Indebtedness, Guarantor hereby agrees that any and 
all rights that Guarantor may have or acquire to collect from or to be 
reimbursed by Borrower (or from or by any other guarantor, endorser or surety 
of Borrower's Indebtedness), whether Guarantor's rights of collection or 
reimbursement arise by way of subrogation to the rights of Lender or 
otherwise, shall in all respects, whether or not Borrower is presently or 
subsequently becomes insolvent, be subordinate, inferior and junior to the 
rights of Lender to collect and enforce payment, performance and satisfaction 
of Borrower's then remaining Indebtedness, until such time as Borrower's 
Indebtedness is fully paid and satisfied.  In the event of Borrower's 
insolvency or consequent liquidation of Borrower's assets, through 
bankruptcy, by an assignment for the benefit of creditors, by voluntary 
liquidation, or otherwise, the assets of Borrower applicable to the payment 
of claims of both Lender and Guarantor shall be paid to Lender and shall be 
first applied by Lender to Borrower's then remaining Indebtedness.  Guarantor 
hereby assigns to Lender all claims which it may have or acquire against 
Borrower or any assignee or trustee of Borrower in bankruptcy; provided that, 
such assignment shall be effective only for the 

                                    -40-

<PAGE>

purpose of assuring to Lender full payment of Borrower's Indebtedness 
guaranteed under this Agreement.

If now or hereafter (a) Borrower shall be or become insolvent, and (b) 
Borrower's Indebtedness shall not at all times until paid be fully secured by 
collateral pledged by Borrower, Guarantor hereby forever waives and 
relinquishes in favor of Lender and Borrower, and their respective 
successors, any claim or right to payment Guarantor may now have or hereafter 
have or acquire against Borrower, by subrogation or otherwise, so that at no 
time shall Guarantor be or become a "creditor" of Borrower within the meaning 
of 11 U.S.C. section 547(b), or any successor provision of the Federal 
bankruptcy laws.

GUARANTOR'S RECEIPT OF PAYMENTS.  Guarantor further agrees to refrain from 
attempting to collect and/or enforce any of Guarantor's collection and/or 
reimbursement rights against Borrower (or against any other guarantor, surety 
or endorser of Borrower's Indebtedness), arising by way of subrogation or 
otherwise, until such time as all of Borrower's then remaining Indebtedness 
in favor of Lender is fully paid and satisfied.  In the event that Guarantor 
should for any reason whatsoever receive any payment(s) from Borrower (or any 
other guarantor, surety or endorser of Borrower's Indebtedness) that Borrower 
(or such a third party) may owe to Guarantor, for any of the reasons stated 
above, Guarantor agrees to accept such payment(s) in trust for and on behalf 
of Lender, advising Borrower (or the third party payee) of such fact.  
Guarantor further unconditionally agrees to immediately deliver such funds to 
Lender, with such funds being hold by Guarantor over any interim period, in 
trust for Lender.  In the event that Guarantor should for any reason 
whatsoever receive any such funds from Borrower (or any third party), and 
Guarantor should deposit such funds in one or more of Guarantor's deposit 
accounts, no matter where located, Lender shall have the right to attach any 
and all of Guarantor's deposit accounts in which such funds were deposited, 
whether or not such funds were commingled with other monies of Guarantor, and 
whether or not such funds then remain on deposit in such an account or 
accounts.  To this end and to secure Guarantor's obligations under this 
Agreement, Guarantor collaterally assigns and pledges to Lender, and grants 
to Lender a continuing security interest in, any and all of Guarantor's 
present and future rights, title and interest in and to all monies that 
Guarantor may now and/or in the future maintain on deposit with banks, 
savings and loan associations and other entities (other than tax deferred 
accounts with Lender), in which Guarantor may at any time deposit any such 
funds that may be received frm Borrower (or any other guarantor, endorser or 
surety of Borrower's Indebtedness) in favor of Lender.

DEPOSIT ACCOUNTS.  As collateral security for repayment of Guarantor's 
obligations hereunder and under any additional guaranties previously granted 
or to be granted by Guarantor in the future, and additionally as collateral 
security for any present and future indebtedness of Guarantor in favor of 
Lender (with the exception of any indebtedness under a consumer credit card 
account), Guarantor is granting Lender a continuing security interest in any 
and all funds that Guarantor may now and in the future have on deposit with 
Lender or in certificates of deposit or other deposit accounts as to which 
Guarantor is an account holder (with the exception of IRA, pension, and other 
tax-deferred deposits).  Guarantor further agrees that Lender may at any time 
apply any funds that Guarantor may have on deposit with Lender or in 
certificates of deposit or other deposit accounts as to which 

                                    -41-

<PAGE>

Guarantor is an account holder against the unpaid balance of any and all 
other present and future obligations and indebtedness of Guarantor to Lender, 
in principal, interest, fees, costs, expenses, and attorneys' fees.

ADDITIONAL COVENANTS.  Guarantor agrees that Lender may, at its sole option, 
at any time, and from time to time, without the consent of or notice to 
Guarantor, or any of them, or to any other party, and without incurring any 
responsibility to Guarantor or to any other party, and without impairing or 
releasing any of Guarantor's obligations or liabilities under this Agreement:

     (a)  Make additional secured and/or unsecured loans to Borrower.

     (b)  Discharge, release or agree not to sue any party (including, but not
     limited to, Borrower or any other guarantor, surety, or endorser of
     Borrower's Indebtedness), who is or may be liable to Lender for any of
     Borrower's Indebtedness.

     (c)  Sell, exchange, release, surrender, realize upon, or otherwise deal
     with, in any manner and in any order, any collateral directly or indirectly
     securing repayment of any of Borrower's Indebtedness.

     (d)  Alter, renew, extend, accelerate, or otherwise change the manner,
     place, terms and/or times of payment or other terms of Borrower's
     Indebtedness, or any part thereof, including any increase or decrease in
     the rate or rates of interest on any of Borrower's Indebtedness.

     (e)  Settle or compromise any of Borrower's Indebtedness.

     (f)  Subordinate and/or agree to subordinate the payment of all or any part
     of Borrower's Indebtedness, or Lander's security rights in any collateral
     directly or indirectly securing any such Indebtedness, to the payment
     and/or security rights of any other present and/or future creditors of
     Borrower.

     (g)  Apply any payments and/or proceeds to any of Borrower's Indebtedness
     in such priority or with such preferences as Lender may determine in its
     sole discretion, regardless of which of Borrower's Indebtedness then
     remains unpaid.

     (h)  Take or accept any other collateral security or guaranty for any or
     all of Borrower's Indebtedness.

     (i)  Enter into, deliver, modify, amend, or waive compliance with, any
     instrument or arrangement evidencing, securing or otherwise affecting, all
     or any part of Borrower's Indebtedness.

NO IMPAIRMENT OF GUARANTOR'S OBLIGATIONS.  No course of dealing between 
Lender and Borrower (or any other guarantor, surety or endorser of Borrower's 
Indebtedness), nor any failure or delay on the part of Lender to exercise any 
of Lender's rights and remedies under this 

                                    -42-

<PAGE>

Agreement or any other agreement or agreements by and between Lender and 
Borrower (or any other guarantor, surety or endorser), shall have the effect 
of impairing or releasing Guarantor's obligations and liabilities to Lender, 
or of waiving any of Lender's rights and remedies under this Agreement or 
otherwise.  Any partial exercise of any rights and remedies granted to Lender 
shall furthermore not constitute a waiver of any of Lender's other rights and 
remedies; it being Guarantor's intent and agreement that Lender's rights and 
remedies shall be cumulative in nature.  Guarantor further agrees that, 
should Borrower default under any of its Indebtedness, any waiver or 
forbearance on the part of Lender to pursue Lender's available rights and 
remedies shall be binding upon Lender only to the extent that Lender 
specifically agrees to such waiver or forbearance in writing.  A waiver or 
forbearance on the part of Lender as to one event of default shall not 
constitute a waiver or forbearance as to any other default.

NO RELEASE OF GUARANTOR.  Guarantor's obligations and liabilities under this 
Agreement shall not be released, impaired, reduced, or otherwise affected by, 
and shall continue in full force and effect notwithstanding the occurrence of 
any event, including without limitation any one or more of the following 
events:

     (a)  The death, insolvency, bankruptcy, arrangement, adjustment,
     composition, liquidation, disability, dissolution, or lack of authority
     (whether corporate, partnership or trust) of Borrower (or any person acting
     on Borrower's behalf), or of any other guarantor, surety or endorser of
     Borrower's Indebtedness.

     (b)  Any payment by Borrower, or any other-party, to Lender that is held to
     constitute a preferential transfer or a fraudulent conveyance under any
     applicable !aw, or any such amounts or payment which, for any reason,
     Lender is required to refund or repay to Borrower or to any other person.

     (c)  Any dissolution of Borrower, or any sale, lease or transfer of all or
     any part of Borrower's assets.

     (d)  Any failure of Lender to notify Guarantor of the making of additional
     loans or other extensions of credit in reliance on this Agreement.

AUTOMATIC REINSTATEMENT.  This Agreement and Guarantor's obligations and 
liabilities hereunder shall continue to be effective, and/or shall 
automatically and retroactively be reinstated, if a release or discharge has 
occurred, or if at any time, any payment or part thereof to Lender with 
respect to any of Borrower's Indebtedness, is rescinded or must otherwise be 
restored by Lender pursuant to any insolvency, bankruptcy, reorganization, 
receivership, or any other debt relief granted to Borrower or to any other 
party to Borrower's Indebtedness or any such security therefor.  In the event 
that Lender must rescind or restore any payment received in total or partial 
satisfaction of Borrower's Indebtedness, any prior release or discharge from 
the terms of this Agreement given to Guarantor shall be without effect, and 
this Agreement and Guarantor's obligations and liabilities hereunder shall 
automatically and retroactively be renewed and/or reinstated and shall remain 
in full 

                                    -43-

<PAGE>

force and effect to the same degree and extent as if such a release or 
discharge had never been granted.  It is the intention of Lender and 
Guarantor that Guarantor's obligations and liabilities hereunder shall not be 
discharged except by Guarantor's full and complete performance and 
satisfaction of such obligations and liabilities; and then only to the extent 
of such performance.

LEGAL EXISTENCE.  Guarantor is a corporation duly organized, validly existing 
and in good standing under the laws of the State of Oklahoma.  Guarantor is 
duly qualified and in good standing as a foreign corporation in each 
jurisdiction where in the nature of the business transacted and the property 
owned by Guarantor makes such qualification necessary.  Guarantor's guaranty 
of Borrower's Indebtedness and this Agreement does not violate Guarantor's 
Articles of incorporation or Bylaws.  Guarantor has taken all corporate 
action necessary to authorize the execution, delivery and performance of this 
Agreement.

     property may be bound.

     (c)  Guarantor has agreed and consented to execute this Agreement and to

     material benefit from the transactions contemplated herein and/or arising
     out of Borrower's Indebtedness.

ADDITIONAL OBLIGATIONS OF GUARANTOR.  So long as this Agreement remains in 
effect, Guarantor has not and will not, without Lender's prior written 
consent, sell, lease, assign, pledge, hypothecate, encumber, transfer, or 
otherwise dispose of all or substantially all of Guarantor's assets.

<PAGE>

have no obligation to disclose to Guarantor any information or material 
relating to Borrower or Borrower's Indebtedness.

ADDITIONAL DOCUMENTS; FINANCIAL STATEMENTS.  Upon the reasonable request of 
Lender, Guarantor will, at any time, and from time to time, execute and 
deliver to Lender any and all such financial instruments and documents, and 
supply such additional information, as may be necessary or advisable in the 
opinion of Lender to obtain the full benefits of this Agreement.  Guarantor 
further agrees to provide Lender with such financial statements and other 
related information at such frequencies and in such detail as Lender may 
reasonably request.

TRANSFER OF INDEBTEDNESS.  This Agreement is for the benefit of Lender and 
for such other person or persons as may from time to time become or be the 
holders of all or any part of Borrower's Indebtedness.  This Agreement shall 
be transferrable and negotiable with the same force and affect and to the 
same extent as Borrower's Indebtedness may be transferrable; it being 
understood and agreed to by Guarantor that, upon any transfer or assignment 
of all or any part of Borrower's Indebtedness, the holder of such 
Indebtedness shall have all of the rights and remedies granted to Lender 
under this Agreement.  Guarantor further agrees that, upon any transfer of 
all or any portion of Borrower's Indebtedness, Lender may transfer and 
deliver any and all collateral securing repayment of such Indebtedness 
(including, but not limited to, any collateral provided by Guarantor) to the 
transferee of such Indebtedness, and such collateral shall secure any and all 
of Borrower's Indebtedness in favor of such a transferee.  Guarantor 
additionally agrees that, after any such transfer or assignment has taken 
place, Lender shall be fully discharged from any and all liability and 
responsibility to Borrower and Guarantor with respect to such collateral, and 
the transferee thereafter shall be vested with all the powers and rights with 
respect to such collateral.

CONSENT TO PARTICIPATION.  Guarantor recognizes and agrees that Lender may, 
from time to time, one or more times, transfer all or any part of Borrower's 
Indebtedness through sales of participation interests in such Indebtedness to 
one or more third party lenders. Guarantor specifically agrees and consents 
to all such transfers and assignments, and Guarantor further waives any 
subsequent notice of such transfers and assignments as may be provided under 
Louisiana law. Guarantor additionally agrees that the purchaser of a 
participation  interest in Borrower's Indebtedness will be considered as the 
absolute owner of a percentage interest of such Indebtedness and that such a 
purchaser will have all of the rights granted under any participation 
agreement governing the sale of such a participation interest.  Guarantor 
waives any rights of offset that Guarantor may have against Lender and/or any 
purchaser of such a participation interest, and Guarantor unconditionally 
agrees that either Lender or such a purchaser may enforce Guarantor's 
obligations and liabilities under this Agreement, irrespective of the failure 
or insolvency of Lender or any such purchaser.

NOTICES.  Any notice provided in this Agreement must be in writing and will be
considered as given on the day it is delivered by hand or deposited in the U.S.
mail, postage prepaid, addressed to the person to whom the notice is to be given
at the address shown above or at such other addresses as any party may designate
to the other in writing.  If there is more than one Guarantor under this

                                    -45-

<PAGE>

Agreement, notice to any Guarantor shall constitute notice to all Guarantors.

ADDITIONAL GUARANTIES.  Guarantor recognizes and agrees that Guarantor may have
previously granted, and may in the future grant, one or more additional
guaranties of Borrower's Indebtedness in favor of Lender.  Should this occur,
the execution of this Agreement and any additional guaranties on the part of
Guarantor will not be construed as a cancellation of this Agreement or any of
Guarantor's additional guaranties; it being Guarantor's full intent and
agreement that all such guaranties of Borrower's Indebtedness in favor of Lender
shall remain in full force and effect and shall be cumulative in nature and
effect.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Guaranty:

   Amendment.  No amendment, modification, consent or waiver of any 
   provision of this Agreement, and no consent to any departure by 
   Guarantor therefrom, shall be effective unless the same shall be in 
   writing signed by a duly authorized officer of Lender, and then shall be 
   effective only as to the specific instance and for the specific purpose 
   for which given.

   Applicable Law.  This Guaranty has been delivered to Lender and accepted

   are for convenience purposes only and are not to be used to interpret or 
   to define their provisions.  In this Agreement, whenever the context so 
   requires, the singular includes the plural and the plural also includes 
   the singular.

   Severability.  If any provision of this Agreement is hold to be illegal, 
   invalid or unenforceable under present or future laws effective during 
   the term hereof, such provision shall be fully severable.  This 
   Agreement shall be construed and enforceable as if the illegal, invalid 
   or unenforceable provision had never comprised a part of it, and the 
   remaining provisions of this Agreement shall remain in full force and 
   effect and shall not be affected by the illegal, invalid or 
   unenforceable provision or by its severance herefrom.  Furthermore, in 
   lieu of such illegal, invalid or unenforceable provision, there shall be 
   added automatically as a part of this Agreement, a provision as similar 
   in terms to such illegal, invalid or unenforceable provision as may be 
   possible and legal, valid and enforceable.

   Successors and Assigns Bound.  Guarantor's obligations and liabilities 
   under this Agreement shall be binding upon Guarantor's successors, 
   heirs, legatees, devisees, administrators, executors and assigns.

   Waive Jury.  Guarantor and Lender hereby waive the right to any jury 
   trial in any action, proceeding, or counterclaim brought by either 
   against the other.
