                        VIROGROUP, INC., AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  MAY 31, 1998
                                   (UNAUDITED)


(1)     Basis of Presentation

The consolidated balance sheet as of August 31, 1997, which has been derived
from audited statements, and the unaudited interim consolidated financial
statements included herein, have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Certain information and
note disclosures normally included in annual financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to those rules and regulations, although the Company believes
that the disclosures made are adequate to make the information presented not
misleading.

In the opinion of the Company, the accompanying unaudited consolidated financial
statements contain all adjustments (consisting of only normal recurring
accruals) necessary to present fairly the financial position of the Company as
of May 31, 1998 and the results of operations and cash flows for the three-month
and nine-month periods ended May 31, 1998 and May 31, 1997.

The accounting policies followed for quarterly financial reporting purposes are
the same as those disclosed in the Company's audited financial statements
contained in its Annual Report on Form 10-K for the year ended August 31, 1997,
as filed with the Securities and Exchange Commission.

(2)     Going Concern

The accompanying consolidated financial statements have been prepared on a going
concern basis, which contemplates continuity of operations, realization of
assets and liquidation of liabilities through the ordinary course of business.
The Company has incurred losses for the past three years beginning with fiscal
year ended August 31, 1995 and has been dependent upon Laidlaw, Inc. or one of
its affiliates to guarantee the Company's bank line of credit. In accordance
with the preferred stock conversion agreement of June 26, 1995, any amounts
borrowed from Laidlaw on June 26, 1998 will convert to a three year term loan
with quarterly amortization payments. However, rather than loaning funds
directly to the Company, Laidlaw extended its Letter of Credit guarantee of the
Company's bank line of credit through August 30,1998, at which time amounts
borrowed will be converted to a three year term.


                                  Page 7 of 21
<PAGE>   8



If operation losses continue, the Company may not be able to generate sufficient
cash flow to service the term debt or to fund operations.

The financial statements do not include any adjustments relating to the
recoverability and classification of asset carrying amounts or the amounts and
classification of liabilities that might result if the Company is unable to
continue as a going concern.

Management is aware of the possibility of not being able to continue as a going
concern and has implemented the following actions in its fiscal 1998 business
plan in an effort to maintain the Company's continuity as a going concern:

(a)        Implementation of  cost containment procedures.

(b)        Increasing focus on profitability by placing increased emphasis on
           products and services which are in high demand and which carry a
           higher profit margin than traditional services.

(c)        Closing of small, non-profitable offices and disposing of assets
           which are not needed.

(d)        Restructuring all locations to more properly meet the immediate needs
           of each location.

(e)        Centralizing controls for operations and for administrative
           functions, such as accounting, credit management and contract
           administration.

If this business plan is not successful, the Company may not be able to continue
as a going concern. The Company's recent history has shown an inability to meet
its business plan projections.

(3)        One-for-Eight Reverse Stock Split

On January 23, 1997, the Company implemented a one-for-eight reverse stock split
of the Company's common stock. The effect of the reverse split upon holders of
the Company's common stock, is that the total number of shares of the Company's
common stock held by each shareholder was automatically converted into that
number of whole shares of common stock equal to the number of shares of common
stock owned immediately prior to the reverse split divided by eight, adjusted
for any fractional shares.

The Company has an authorized capitalization of 50,000,000 shares of common
stock, par value $.01 per share. The authorized capital stock of the Company was
not reduced or otherwise affected by the reverse split. As of January 23, 1997,
the


                                  Page 8 of 21
<PAGE>   9



Company had 6,361,708 shares of common stock issued and outstanding. The
aggregate number of shares of common stock issued and outstanding following the
reverse split is 795,188. All common shares and per share amounts have been
adjusted to give retroactive effect of the reverse split.

The reverse split was effectuated as an attempt to enable the Company to remain
in compliance with the listing criteria of the Nasdaq SmallCap Market; however,
the Company's stock was delisted as of December 30, 1997.

(4)        Loss Per Share

Loss per share is calculated by dividing net loss attributed to common
shareholders by the weighted average number of common shares and common share
equivalents outstanding during the periods. Common share equivalents are not
considered for periods in which there is a loss, since their impact would be
anti-dilutive. Primary and fully diluted loss per share amounts are the same for
all periods presented.

(5)        Florida Underground Petroleum Storage Tank (UST) Reimbursement
           Program, Amounts Due from State Agency and the Concentration of
           Credit Risk.

During fiscal 1994, the Company aggressively expanded its participation in the
State of Florida financed programs to provide environmental services to
evaluate, assess and remediate contaminated underground petroleum storage tank
sites. Through its Inland Protection Trust Fund, the State of Florida reimbursed
certain costs to clean up eligible contaminated sites. Primarily due to an
estimated unfunded $450 million backlog and annual tax revenue allocation of
only $100 million, in March 1995 new legislation directed the Florida Department
of Environmental Protection to cease processing, with certain limited
exceptions, applications for reimbursement of costs to clean up UST sites
eligible for state funds.

In May, 1996 a new law (the "1996 Act") was passed which implemented significant
changes to the reimbursement program and addressed the estimated $450 million
backlog of unpaid claims. The 1996 Act provided for the elimination of the
reimbursement program effective August 1, 1996 and required all reimbursement
applications to be submitted by December 31, 1996. Also, the 1996 Act created a
non-profit public benefit corporation, which became operational during the Fall
of 1997, to finance the unpaid backlog. This non-profit corporation was charged
with financing the estimated backlog of 9,500 claims totaling over $556 million.
Payment of claims is on a first-come, first-served methodology based on
application filing date and an assumed annual allocation rate of $100 million.
Claims paid are subject to a 3.5% annual discount in consideration of the
anticipated accelerated payment as compared to the previously expected period of
4 to 5 years. Payment of the initial portion of the claims (approximately $213
million) was made in March, 1998. A



                                  Page 9 of 21
<PAGE>   10



smaller payment was made by the State of Florida in May, 1998. Based on
information received from the State of Florida, additional payments will be made
periodically as additional claims packages are reviewed; however, no assurances
can be given that a specific payment timetable will be maintained.

The Company in prior fiscal years recorded valuation allowances on the amounts
due to reflect the State mandated discount and potential denied costs. At August
31, 1997 these allowances totaled $913,918, of which $166,623 was applied as a
valuation allowance to the Amounts Due from State Agency, resulting in a net
amount of $512,927 shown in the accompanying consolidated balance sheet. The
remaining $747,295 is included as an accrued liability to reflect the Company's
potential liability to pay discounts and denied costs on receivables sold to
third-parties.

At May 31, 1998, these allowances totaled $687,712, of which $108,700 was
applied as a valuation allowance to the Amounts Due from State Agency, resulting
in a net of $323,159 shown in the accompanying consolidated balance sheet. The
remaining $579,012 is included as an accrued liability to reflect the Company's
potential liability to pay discounts and denied costs on receivables sold to
third parties.

Approximately $3.1 million in reimbursement applications had been sold to third
party entities at August 31, 1997. The Company used third party funding to avoid
the long payout period by the State. As of May 31, 1998, approximately
$2,000,000 of those reimbursement applications had been paid leaving an
unreimbursed balance of approximately $1,100,000. In addition to selling the
previously mentioned claims, the Company filed approximately $703,000 of claims
directly with the State.

Specifically, the Company entered into several arrangements to sell
substantially all the claims filed with the State for reimbursement. These
arrangements required the Company to pay a 3 - 4% prepaid fee at the time the
buyers paid the Company.

Because the State did not pay the funding entities by September 30, 1997, the
Company began paying indemnification costs at a rate of 0.6875% in October 1997.
Under the agreement with the funders, the monthly rate increases such that if
the applications are not paid by the State prior to the 20th month after
funding, the Company will have paid indemnification costs at the rate of 0.6875%
for 18 months. If the applications are not paid within 20 months, the Company
must indemnify the funders at the rate which would have otherwise been received
by the funders from the State program if interest were being paid by the State.
These indemnification costs are being charged against the reserve account at the
present time. In the event the State does not meet the projected payment
schedule beginning in the first quarter



                                 Page 10 of 21
<PAGE>   11



of calendar year 1998, the reserves will not be adequate to absorb all of the
indemnification costs.

Although payments made by the State of Florida in March and May, 1998, reduced
the Company's exposure for indemnification costs, discounts, and disallowed
costs, as of July 10, 1998, the Company is unable to estimate that reduced
exposure.

In addition, the Company has placed 13% of the amounts sold in an interest
bearing escrow account to provide for potential state denied costs and state
mandated interest discount. The interest earned on the escrowed amounts accrues
to the Company's benefit and is recorded as interest income in the period
earned. The escrow balance at May 31, 1998 and August 31, 1997 was $306,493 and
$596,408, respectively, and is included in restricted cash on the accompanying
Consolidated Balance Sheet.

The Company filed all amounts due from the State prior to the state mandated
filing deadline of December 31, 1996.

(6)        Notes Payable

Notes payable at May 31, 1998 and August 31, 1997, consisted of advances against
a $3.0 million line of credit. Under this line of credit, the Company may borrow
up to $3.0 million at an interest rate of prime (8.50% at May 31, 1998) less
 .25%. Laidlaw, Inc. (Laidlaw) in lieu of its commitment to provide up to $3.0
million in debt financing to the Company pursuant to the terms of the preferred
stock conversion agreement of June 26, 1995, caused a letter of credit to be
issued to collateralize the $3.0 million line of credit. Substantially all of
the Company's assets secure this obligation to Laidlaw in the event of a draw
upon the letter of credit. As of June 26, 1998, the letter of credit was reduced
from $3,000,000 to $1,700,000 and its termination date was extended. The line of
credit now expires August 30, 1998 and the letter of credit expires September
30, 1998. Laidlaw has stated it will comply with the terms of the preferred
stock conversion agreement at the letter's expiration, and an affiliate will
make available to the Company for a three-year period up to $1.7 million in
financing with advances thereunder carrying an interest rate equal to that
available to the Company from alternative sources with the principal and
interest to be paid in equal quarterly installments over the three-year period
commencing with the line of credit expiration.

(7)        Restructuring Charge

Primarily due to the May 1996 law relating to the Florida UST Program and a
continued decline in forecasted landfill design work, as well as general market
conditions, the company closed two non-profitable satellite offices in Tampa,
Florida


                                 Page 11 of 21
<PAGE>   12



and Jacksonville, Florida and reduced the size of its Lexington, South Carolina
office by approximately one-third. A restructuring charge of $237,755 was
included in the August 31, 1997 Consolidated Statement of Operations. These
restructuring charges consisted primarily of employee severance and rent expense
and the $237,755 is included in Accrued liabilities on the August 31, 1997
consolidated balance sheet. For the nine month period ended May 31, 1998,
$206,653 had been charged against the accrual primarily for employee severance
pay and lease expenses on closed offices. The Company believes the balance of
$31,102 in the accrual account at May 31, 1998 is adequate to absorb the
remaining estimated costs.

(8)        Segment Information

The Company operates in one industry segment, as contemplated by Financial
Accounting Standards Board Statement No. 14. International Comfort Products
accounted for approximately 15% and Laidlaw and its affiliates accounted for
approximately 18% of consolidated revenues for the nine months ended May 31,
1998. Amounts due from these clients total $270,422 and are included in Accounts
receivable, net in the accompanying consolidated balance sheet for May 31, 1998.
A Laidlaw affiliate owns 50% of the Company's outstanding common stock and three
officers of Laidlaw affiliates are Directors of the Company.

(9)        Legal

The Company has been notified by the Environmental Protection Agency, through a
General Notice Letter that the Company is a potentially liable party at the
Florida Petroleum Reprocessors Site in Davie, Florida. However, at this time, no
estimate of the potential liability can be calculated due to the limited amount
of information available. This type of liability is an insurable risk and the
Company's insurance carrier has been notified; however, no formal claim has been
filed at this time. The insurance policy has a deductible of $250,000.
Management is of the opinion that Company liability will be minimal, if any.

The Company has been sued by Housing Authority of the City of Miami Beach
claiming damages on a project that was completed in 1994. The potential
liability for this suit is approximately $85,000.00. Management is of the
opinion that the Company will have minimal liability, if any, and intends to
vigorously defend itself against the claim.

(10)       Proposed Merger

On June 23, 1998, the Company and Laidlaw Environmental Services, Inc. signed a
merger agreement whereby Laidlaw Environmental Services will acquire all non-
Laidlaw owned shares of the Company for $0.75 per share. This agreement is
subject to approval of the Securities and Exchange Commission and the Company
shareholders.

The primary reasons for the decreases in gross revenues are as follows:

The majority of the decrease in the South Carolina operations of $122,611 was
due to a decrease in landfill design work in South Carolina. The Tennessee gross
revenues decrease of $344,411 was due to having two large projects in progress
last

fiscal year which have not been replaced in the current year and an overall
reduction in volume for remedial projects.

Cost of gross revenues is 73.7% of revenues for the three months ended May 31,
1998, compared to 70.5% for the three months ended May 31, 1997. This change
primarily results from decreased gross revenues and significant industry
competition for the current year.

Selling, general, and administrative expenses for the three months ended May 31,
1998 decreased by $360,707 to $684,429, as compared to $1,045,136 for the same
period of the prior year. The majority of this improvement is due to staff
downsizing and reductions in overhead expenses.

Net interest expense decreased due to charging accrued UST indemnification
expenses against the reserve instead of to the interest expense account.

The net loss for the three months ended May 31, 1998 was $408,950 compared to a
net loss of $627,054 for the same period of the prior year. This improvement is
primarily the result of the decrease in overhead costs.

Comparison of nine months ended May 31, 1998 and May 31, 1997. Gross revenues
decreased by 33% to $3,816,950 for the nine months ended May 31, 1998 compared
to $5,683,545 for the same period of fiscal year 1997. This decrease in gross
revenues results from the decrease in gross revenues in the Company's
Environmental (Enviro) division, as shown in the following table:

Florida Enviro operations had a decrease in gross revenues of $157,703 from the
prior year. This decrease primarily results from the closure of the two small,
unprofitable offices located in Jacksonville and Tampa, in the fourth quarter of
fiscal


                                 Page 14 of 21

1997. The $599,803 decrease in gross revenues from the South Carolina operations
is primarily due to a decrease in landfill design work in South Carolina. The
decrease of $1,105,726 in Tennessee revenues is primarily due to revenues
generated by two large remediation projects which were in progress during the
first and second quarters of last year, which have not been replaced in the
current year. In general, the overall volume of work in the Remedial Division is
down in fiscal 1998.

Cost of gross revenues have improved from 72% of revenues for the first nine
months of fiscal 1997 to 66% of revenues for the first nine months of fiscal
1998. That improvement is primarily the result of operation improvements in the
Hydro Division and in the smaller, more efficient operations in South Carolina.

Selling, general and administrative expenses decreased by $1,070,028. This
decrease was mainly accomplished through the reduction of under-utilized staff,
office closures and management cost controls.

Net interest expense decreased by $78,901 primarily due to charging the UST
indemnification accrual against the reserve instead of expensing it.

The Company has not provided a provision for income taxes due to the current
quarter's net loss and has not recorded any tax benefit. It has provided a 100%
valuation allowance of the deferred tax asset that results from federal and
state net operating loss carry forwards due to the lack of availability of
federal and state taxable income within the carryback period, available under
the federal and state tax laws as well as the inability to determine the
likelihood that future federal and state taxable income will be sufficient to
utilize the deferred tax asset.

The net loss for the nine months ended May 31, 1998 decreased by $862,103
compared to the prior year. This net loss for the first nine months of fiscal
1998 is primarily attributable to the lower-than-projected revenues; however,
the decrease in the loss between years results from the improvement in gross
margins and the decrease in overhead costs.

Liquidity and Capital Resources as of May 31, 1998

The accompanying consolidated financial statements have been prepared on a going
concern basis, which contemplates continuity of operations, realization of
assets, and liquidation of liabilities through the ordinary course of business.
The Company has incurred losses for the past three years beginning with fiscal
year ended August 31, 1995 and has been dependent upon Laidlaw, Inc., or one of
its affiliates, to guarantee the Company's bank line of credit. In accordance
with the preferred stock conversion agreement of June 26, 1995, any amounts
borrowed from Laidlaw on June 26, 1998 will convert to a three-year term loan
with quarterly amortization payments. However, rather than loaning funds
directly to the Company, Laidlaw extended its Letter of Credit guarantee of the
Company's bank line of credit through August 30,


                                 Page 15 of 21
<PAGE>   16



1998, at which time amounts borrowed will be converted to a three year term. If
operating losses continue, the Company may not be able to generate sufficient
cash flow to service the term debt or to fund operations. See Footnote 2 in
Notes to Consolidated Financial Statements for additional details.

The Company's operating activities used net cash of $463,598 for the nine months
ended May 31, 1998. Several factors contributed to this use of cash including
the net operating loss of $883,747.

Working capital, including Amounts Due from State Agency decreased by $793,229.
The decrease in working capital is mainly due to the decrease in regular and
unbilled receivables and the net decrease in Amounts Due from State Agency
($595,675). The decrease in revenues and the payments received from the Florida
Department of Environmental Protection are mainly responsible for the lower
receivables, while more consistent follow up in collections is also a
contributing factor.

Investing activities provided $33,180 from proceeds from sale of equipment in
excess of new equipment purchases.

Financing activities provided cash in the amount of $140,503 which was the net
increase in notes payable.

Inflation has not significantly affected the Company's financial position or
operations. Borrowings under the line of credit bear interest at prime less
 .25%. The prime rate at May 31, 1998 was 8.5%. No assurance can be given that
inflation or the prime rate will not significantly fluctuate, either of which
could adversely affect the Company's results of operations.

During fiscal 1994, the Company aggressively expanded its participation in the
State of Florida financed programs to provide environmental services to
evaluate, assess and remediate contaminated underground petroleum storage tank
sites. Through its Inland Protection Trust Fund, the State of Florida reimbursed
certain costs to clean up eligible contaminated sites. Primarily due to an
estimated unfunded $450 million backlog and annual tax revenue allocation of
only $100 million, in March 1995 new legislation directed the Florida Department
of Environmental Protection to cease processing, with certain limited
exceptions, applications for reimbursement of costs to clean up UST sites
eligible for state funds.

In May, 1996 a new law (the "1996 Act") was passed which implemented significant
changes to the reimbursement program and addressed the estimated $450 million
backlog of unpaid claims. The 1996 Act provided for the elimination of the
reimbursement program effective August 1, 1996 and required all reimbursement
applications to be submitted by December 31, 1996. Also, the 1996 Act created a
non-profit public benefit corporation, which became operational during the Fall
of 1997, to finance the unpaid backlog. This non-profit corporation was charged
with


                                 Page 16 of 21
<PAGE>   17



financing the estimated backlog of 9,500 claims totaling over $556 million.
Payment of claims is on a first-come, first-served methodology based on
application filing date and an assumed annual allocation rate of $100 million.
Claims paid are subject to a 3.5% annual discount in consideration of the
anticipated accelerated payment as compared to the previously expected period of
4 to 5 years. Payment of the initial portion of the claims (approximately $213
million) was made in March, 1998. A smaller payment was made by the State of
Florida in May, 1998. Based on information received from the State of Florida,
additional payments will be made periodically as additional claims packages are
reviewed; however, no assurances can be given that a specific payment timetable
will be maintained.

The Company in prior fiscal years recorded valuation allowances on the amounts
due to reflect the State mandated discount and potential denied costs. At August
31, 1997 these allowances totaled $913,918, of which $166,623 was applied as a
valuation allowance to the Amounts Due from State Agency, resulting in a net
amount of $512,927 shown in the accompanying consolidated balance sheet. The
remaining $747,295 is included as an accrued liability to reflect the Company's
potential liability to pay discounts and denied costs on receivables sold to
third-parties.

At May 31, 1998, these allowances totaled $687,712, of which $108,700 was
applied as a valuation allowance to the Amounts Due from State Agency, resulting
in a net of $323,159 shown in the accompanying consolidated balance sheet. The
remaining $579,012 is included as an accrued liability to reflect the Company's
potential liability to pay discounts and denied costs on receivables sold to
third parties.

Approximately $3.1 million in reimbursement applications had been sold to third
party entities at August 31, 1997. The Company used third party funding to avoid
the long payout period by the State. As of May 31, 1998, approximately
$2,000,000 of those reimbursement applications had been paid leaving an
unreimbursed balance of $1,100,000. In addition to selling the previously
mentioned claims, the Company filed approximately $703,000 of claims directly
with the State.

Specifically, the Company entered into several arrangements to sell
substantially all the claims filed with the State for reimbursement. These
arrangements required the Company to pay a 3 - 4% prepaid fee at the time the
buyers paid the Company.

Because the State did not pay the funding entities by September 30, 1997, the
Company began paying indemnification costs at a rate of 0.6875% in October 1997.
Under the agreement with the funders, the monthly rate increases such that if
the applications are not paid by the State prior to the 20th month after
funding, the Company will have paid indemnification costs at the rate of 0.6875%
for 18 months. If the applications are not paid within 20 months, the Company
must indemnify the funders at the rate which would have otherwise been received
by the funders from


                                 Page 17 of 21
<PAGE>   18



the State program if interest were being paid by the State. These
indemnification costs are being charged against the reserve account at the
present time. In the event the State does not meet the projected payment
schedule beginning in the first quarter of calendar year 1998, the reserves will
not be adequate to absorb all of the indemnification costs.

Although payments made by the State of Florida in March and May, 1998, reduced
the Company's exposure for indemnification costs, discounts, and disallowed
costs, as of July 10, 1998, the Company is unable to estimate that reduced
exposure.

In addition, the Company has placed 13% of the amounts sold in an interest
bearing escrow account to provide for potential state denied costs and state
mandated interest discount. The interest earned on the escrowed amounts accrues
to the Company's benefit and is recorded as interest income in the period
earned. The escrow balance at May 31, 1998 and August 31, 1997 was $306,493 and
$596,408, respectively, and is included in restricted cash on the accompanying
Consolidated Balance Sheet.

The Company filed all amounts due from the State prior to the state mandated
filing deadline of December 31, 1996.
