ITEM 1.  BUSINESS

SUMMARY

   SanTi Group, Inc. ("SanTi" or the "Company"), engages in the following
businesses relating to the nonhazardous liquid waste ("NLW") industry: grease
trap pumping and repair services; septic services (including designing, pumping,
installation and maintenance), sewer and drain cleaning services; high pressure
water jetting services; portable toilet servicing; bulk liquid waste
transportation; biosolids management; on-site biotreatment systems and liquid
waste processing and disposal. SanTi's customers include restaurants, hospitals,
military bases, office buildings, apartments, schools, municipalities,
industrial businesses and single family residences. All references to SanTi or
the Company include its operating subsidiaries unless the context indicates
otherwise.

   SanTi intends to expand its presence in the NLW industry through internal
growth and acquisitions of local service providers throughout the United States.
The acquisitions will be made primarily with cash, shares of the Company's
common stock or a combination of cash and shares of the Company's common stock.
The Company believes that these acquisitions, by consolidating smaller local
service providers, will create synergies and improve efficiencies in the area of
NLW management.

THE NLW INDUSTRY

   The Company estimates that the portable toilet, septic tank and grease trap
business segment of the U.S. domestic NLW industry generates approximately $20
billion in revenues annually. There are approximately 25,000 service providers
currently in the NLW industry and, of these service providers, approximately 75%
generate less than $500,000 of annual revenues. The Company believes the NLW
industry will continue to grow based on increased waste from a growing
population and general economic conditions that are driving new building demand
and the need for NLW services.

   Because the NLW industry is so highly fragmented, management believes the
industry has the potential for significant cost savings by the economies of
scale that may be realized in consolidation. These costs savings would include
efficiencies as a result of common billing, the coordination of advertising, the
elimination of duplicative professional and technical support providers, the
standardization and upgrading of equipment and the improvement of employee
training. SanTi intends to determine lines of the NLW business in which an
acquired service provider is not currently engaged and assist the service
provider in expanding into those areas. There can be no assurance, however, that
SanTi will be able to profitability consolidate service providers within the NLW
industry.

THE BUSINESS

   SanTi currently engages in each of the NLW businesses described above.
SanTi's operating subsidiaries include: Bone-Dry Enterprises, Inc.; SanTi Group
of Florida, Inc.; SanTi Group of Pennsylvania, Inc.; and SanTi Group of New
York, Inc. Each subsidiary of SanTi intends to acquire additional assets from
local service providers and act as an operating division of SanTi in the area in
which it is located. These local operating divisions operate under various
tradenames, as described below.

   Bone-Dry Enterprises, Inc. ( "Georgia Group"). The Georgia Group is engaged
in NLW collection and hauling operations in the state of Georgia. The Georgia
Group operates under the following tradenames: Andrews Environmental, Bone-Dry
Enterprises ("Bone-Dry") and Quality Plumbing and Septic.

   SanTi Group of Florida, Inc. ("Florida Group"). The Florida Group is engaged
in NLW collection and hauling operations in the state of Florida. The Florida
Group operates under the following tradenames: Brownie Environmental Services,
Grease-Tec and A Rapid Rooter Sewer and Drain.


                                      -2-
<PAGE>   3

   SanTi Group of Pennsylvania, Inc. ("Pennsylvania Group"). The Pennsylvania
Group is engaged in NLW collection and hauling operations in the state of
Pennsylvania. The Pennsylvania Group has one wholly owned subsidiary, Nutrecon,
Inc., which holds the operating permits and the leases for a facility acquired
from Ferrero Wastewater Management, Inc., in Ambler, Pennsylvania. The
Pennsylvania Group operates under the following tradenames: Ferrero Wastewater
Management and Eldredge Wastewater Management.

   SanTi Group of New York, Inc. ("New York Group"). The New York Group is
engaged in NLW collection and hauling operations in the state of New York. The
New York Group operates under the following tradenames: RGM Liquid Waste Removal
and Devito Environmental.

   The Company receives fees to collect, process and dispose of nonhazardous
liquid wastes. Collection fees charged to customers vary per gallon by waste
stream according to constituents of the waste, expenses associated with
processing the waste and competitive factors. Grease trap waste from restaurant
and other food processing and preparation facilities are transported to SanTi's
facilities in vacuum trucks, trailers and other transportable containers. SanTi
operates a fleet of vehicles to collect waste directly from generators and
receives waste from independent transporters servicing additional waste
generators. Using a variety of physical, chemical, thermal and other biological
techniques, the waste is broken down into constituent components. Water
extracted from the waste is pretreated and then discharged into the municipal
sanitary sewer system or applied to leased grasslands. Solid materials are dried
and disposed of in a solid waste landfill. At some locations where the Company
does not have pretreatment facilities, the waste is transported to private
pretreatment facilities, or, where permitted by local regulations, directly to
municipal or private wastewater treatment facilities.

   SanTi also engages in the business of biosolids management through the reuse
of organic materials. SanTi provides transportation, treatment, site monitoring,
and land application to private companies. SanTi's vehicles pick up and
transport biosolids to various sites. SanTi also provides professional
management and consulting services for treatment of biosolids and the monitoring
and application onto leased grasslands of treated biosolids.

   The Company benefits from federal, state and local regulations prohibiting
the disposal of grease trap waste and other waste in municipal collection and
treatment systems. Although restaurants, food manufacturing and preparation
facilities and other industrial operations have produced such waste for many
years, regulations governing the management of NLW, and the enforcement of such
regulations, are becoming increasingly stringent. These requirements have
increased the value of SanTi's services to its customers in recent years. As
federal, state and local regulations governing the disposal of NLW increase,
SanTi believes the amount of NLW products delivered to third parties for
processing and disposal will continue to increase.

   SanTi will target the acquisition and integration of local service providers
in the NLW industry that SanTi believes will be profitable additions to the
Company. SanTi intends to focus on the integration of entities acquired and to
increase profits and productivity through operational and efficiency
improvements, standardization of procedures, equipment standards and procurement
procedures.

   SanTi intends to establish local operating facilities or service centers
throughout the United States, with initial service centers established in major
population centers. Acquired local service providers in these areas will be
converted to service centers. A service center manager at each location will be
responsible for the service center's overall performance. The manager will be
supported by supervisors responsible for one or more lines of business. The
manager will also be supported by maintenance managers responsible for the
maintenance and repair of all equipment. The service center managers will report
to district managers, who will typically have responsibility for eight to twelve
service center managers. The district managers will have general management
responsibility for their geographical areas.

Predecessor Corporations

   SanTi Group, Inc. ("SGI"), a privately-held corporation, was incorporated in
Delaware on August 19, 1997 for the purpose of engaging, through its operating
subsidiaries, in the following businesses related to the NLW industry: grease
trap pumping, septic tank services (including designing, pumping, installation,
and maintenance), sewer and drain cleaning services; high pressure jetting
services; portable toilet servicing; bulk liquid waste transportation; biosolids
management; on-site biotreatment systems and liquid waste processing and
disposal. In December 1997, SGI acquired the assets of Bone-Dry in a share
exchange in which each share of Bone-Dry was exchanged for 1.3 shares of SGI.
Bone-Dry was formed in March 1997 to acquire businesses in the NLW industry. SGI
and Bone-Dry were primarily controlled by Mr. Raymond M. Cash, Vice Chairman of
the Board of Directors of the Company, and entities controlled by Mr. Cash.
Following a stock split effected in the form of a 0.25 per share stock dividend
effective January 30, 1998 (the "Stock Dividend"), SGI had approximately
8,088,379 shares of common stock, $.0001 par value per share (the "SGI Stock"),
issued and outstanding as of the date of the merger of SGI into Microlytics,
Inc., as described below. In addition to the issued and outstanding shares, SGI
had a total of 131,250 shares subject to employee options. Of these options,
3,750 were vested as of August 28, 1998.

   Microlytics, Inc. ("Micro") was incorporated in Delaware in 1985 for the
purposes of engaging in the business of developing, manufacturing and marketing
electronic reference products, including computer software programs which
provided linguistic and information compression technology, bilingual
dictionaries and thesaurus products. In 1989, Micro operated as a wholly owned
subsidiary of Selectronics, Inc. ("Selectronics"). In 1995, Selectronics changed
its name to Microlytics, Inc. In the early 1990's, Micro began experiencing
financial difficulties as a result of the highly competitive nature of the
computer software industry. On November 27, 1996, Micro filed for protection
under Chapter 11 of the United States Bankruptcy Code in the United States
Bankruptcy Court for the Western District of New York (the "Court"). In July of
1997, substantially all of the intangible assets of Micro and its subsidiary
were sold to Metro One Telecommunications, Inc. In August of 1997, substantially
all of the tangible assets of Micro were also sold. The proceeds of these sales
were held in a segregated trust account by the debtor's counsel prior to the
Court's confirmation of Micro's plan of reorganization.

   In April of 1998, Micro filed a Plan of Reorganization (the "Plan") that was
approved by its shareholders, the creditor's committee and the Court. Pursuant
to the Plan, Micro effected a 1 for 400 reverse stock split, distributed the
proceeds from asset liquidations to its creditors, and distributed shares and
warrants to its creditors and shareholders. The Plan provided for this reverse
stock split prior to the merger of SGI and Micro, as described below. Pursuant
to the Plan, any shareholder of Micro as of April 30, 1998 who, as a result of
the 1 for 400 reverse stock split, held less than 100 shares, had his or her
shares rounded up to 100 shares. As of July 20, 1998, after the 1 for 400
reverse stock split and rounding of shares, 1,027,066 shares of Micro common
stock were issued and outstanding. Also under the Plan, Micro issued warrants
for 500,000 shares of Micro common stock, exercisable at $5.80 per share.

The Merger

   On May 13, 1998, SGI was merged with and into Micro under an agreement and
plan of merger, with Micro surviving and changing its name to SanTi Group, Inc.
("the Merger"). The Merger was subject to the approval of the Court. On the
effective date of the Merger, each issued and outstanding share of SGI Stock was
converted into one share of common stock of Micro (now SanTi), (the "Common
Stock"). These exchange ratios were determined after the  1 for 400 reverse
split of Common Stock pursuant to the Plan. This exchange resulted in the
receipt by SGI shareholders of approximately 8,088,379 shares of Common Stock,
representing approximately 86.2% of the shares of Common Stock issued and
outstanding on the effective date of the Merger. As of August 28, 1998, after
the issuance of shares pursuant to the Plan, the Merger, the reverse split, and
the exercise of warrants to acquire 304,746 shares of Common Stock, SanTi had
9,526,599 shares of Common Stock outstanding. All options to acquire shares of
SGI Stock were also converted into options to receive shares of Common Stock. As
of August 28, 1998, options to acquire 3,750 were vested and 22,500 vest over
the next two years. SanTi succeeded to all of the assets, liabilities and NLW
business of SGI.

Acquisitions

   SanTi intends to expand its business in the NLW industry through internal
growth and the acquisition of local NLW service providers throughout the United
States. These acquisitions will be made with cash, shares of Common Stock, or a
combination of cash and shares of Common Stock. SanTi's acquisition strategy has
been developed with the goal of increasing the efficiency and profitability of
acquisition targets through operational and marketing synergies with SanTi's
existing business operations. SanTi will provide professional management to
these acquired entities to eliminate duplicative processes and procedures among
the acquired businesses. The services that SanTi intends to provide to the
acquired entities include: sales management, accounts receivable and accounts
payable management, debt collection, financial reporting, tax management,
advertising, purchasing, legal, health and safety, environmental, human
resources, training and capital. Customer service representatives will also be
provided. These services are intended to allow the local managers to focus on
the growth of regional business.

   Between March 1997 and July 1998, SanTi (or Bone-Dry) completed several
acquisitions of NLW local service providers. These acquisitions geographically
extended SanTi's processing operations to New York, Philadelphia and Miami, and
increased its market penetration in Georgia. The total cost of the acquisitions,
including contingent consideration, was $21,374,120 in cash, $2,257,350 in notes
to sellers and 565,000 shares of Common Stock. In addition, SanTi entered into
one-year agreements with certain key managers that include severance payments if
terminated before expiration.

     Andrews Environmental, Inc. ("Andrews"). In March 1997, Bone-Dry acquired a
portion of the assets of Andrews, operating as Andrews' grease disposal business
for $475,000 in cash and $257,350 in notes. Andrews was in the business of
commercial and governmental grease extraction, collection, and transportation
services in the state of Georgia. In December 1997, Bone-Dry acquired the
remaining assets of Andrews for $660,000 in cash and 21,400 shares of Common
Stock. Contingent consideration of 13,600 shares of Common Stock is payable
within 90 days of the first anniversary of the date of the purchase, net of
offsets for losses, as defined in the purchase agreement. These assets included
customer accounts, trucks and containers to be used in the NLW and septic waste
collection, transportation, management and disposal business. Andrews
specializes in the area of NLW and disposal in Georgia.

     Atlanta Grease Trap ("Atlanta Grease"). In August 1997, Bone-Dry acquired
the assets of Atlanta Grease, for approximately $360,000 in cash. Atlanta Grease
was in the business of commercial and governmental grease extraction, collection
and transportation services in Georgia. The assets acquired included customer
accounts, software, and certain physical assets to be used in the NLW and septic
waste collection, transportation, management and disposal business.

     Ferrero Wastewater Management, Inc. ("Ferrero"). In January 1998, the
Pennsylvania Group acquired the assets of Ferrero for $2,240,100 in cash and
90,000 shares of Common Stock. Contingent consideration of $248,900 in cash and
10,000 shares of Common Stock is payable 270 days after the date of purchase,
net of offsets for losses, as defined in the purchase agreement. These assets
included customer accounts, trucks and containers to be used in the business of
NLW and septic waste collection, transportation and management and disposal in
the Ambler, Pennsylvania area. In connection with this asset purchase, the
Pennsylvania Group agreed to assume certain liabilities of Ferrero, excluding
any liability for environmental, health and safety requirements and any taxes
arising out of the asset purchase. All third party liabilities were paid by
Ferrero prior to the closing.

     A Rapid Rooter Sewer and Drain Service, Inc. ("A Rapid"). In February 1998,
the Florida Group acquired the assets of A Rapid for $3,300,000 in cash, payment
of existing debt totaling approximately $690,120 and 100,000 shares of Common
Stock. These assets included customer accounts, trucks, containers and other
assets used in the NLW collection and disposal business. A Rapid operates
primarily in the Miami/Dade, Broward and Palm Beach, Florida areas. In
connection with this asset purchase, the Florida Group agreed to assume certain
liabilities of A Rapid, excluding any liability for environmental, health and
safety requirements and any taxes arising out of the asset purchase. All third
party liabilities were paid by A Rapid prior to the closing.

requirements and any taxes arising out of the asset purchase. All third party
liabilities were paid by Eldredge prior to the closing.

     In connection with each acquisition, SanTi may have assumed or succeeded to
certain liabilities of the acquired businesses, which may include environmental
liabilities except as described above. SanTi has obtained representations from
the sellers of the acquired businesses that no undisclosed liabilities exist and
certain rights to indemnification from the sellers for any liabilities. There
can be no assurance, however, that undisclosed liabilities do not exist or that
SanTi will receive full or partial compensation pursuant to its rights to
indemnification.


                                      -6-
<PAGE>   7

     In addition to internal growth, the growth of SanTi, to a significant
extent, will depend on its continued acquisition of NLW service providers. SanTi
expects competition to exist in the industry to acquire these candidates, which
may limit the number of acquisition opportunities and may lead to higher
acquisition prices. Acquisitions of these entities entail various risks,
including failure of the acquired service providers to achieve expected results,
diversion of management's attention, failure to retain key personnel of the
acquired service providers and risks associated with unanticipated events and
liabilities. All of these risks may have an adverse effect on the ability of
SanTi to acquire additional acquisition candidates and on its business condition
and results of operations. Any complementary businesses that are acquired also
may not be successfully integrated.

Debt Financing

     SanTi obtained a revolving line of credit on June 26, 1998 from Bank of
America National Trust and Savings Association ("Bank of America"), acting as an
agent for various lending institutions, including Bank of America (collectively,
the "Banks"). Under this credit agreement, each of the lending institutions
agrees to make loans to, and to issue or participate in the issuance of letters
of credit for the account of SanTi on a revolving basis during the term of the
agreement as requested by SanTi (the "Credit Agreement"). The total outstanding
revolving credit and the aggregate amount of all letters of credit outstanding
are not to exceed the commitment amount of $40,000,000. Various financial
covenants in the Credit Agreement restrict the Company's ability to draw on this
line of credit. A pledge agreement was executed concurrent with the Credit
Agreement, requiring SanTi to pledge all shares of stock owned by SanTi in each
of its subsidiaries (both current subsidiaries as well as any subsidiary formed
in the future), as security for the payment of all liabilities incurred under
the revolving line of credit. A security agreement provides for a continuing
security interest to the Banks in all of the subsidiaries' accounts receivable,
certified securities, chattel paper, computer hardware and software, contract
rights, deposit accounts, documents, general intangibles, goods, instruments,
intellectual property, money, commodities, uncertified securities and all
personal property. A stock purchase warrant was also granted to Bank of America
for the right to purchase 50,000 shares of SanTi common stock at a price of
$13.00 per share, expiring on June 26, 2003. SanTi anticipates that it will use
this line of credit, alone or in combination with shares of its Common Stock, to
acquire local NLW service providers, as well as for working capital.

Competition

     SanTi competes with a significant number of other NLW service providers.
Competitors compete primarily on the basis of proximity to collection
operations, fees charged and quality of service. Future technological changes
and innovations may result in a reduction in the amount of NLW generated, or in
alternative methods of treatment and disposal being developed. SanTi also faces
competition from customers that may seek to enhance and develop their own
methods of disposal. Increased use of internal treatment and disposal methods
and other competitive factors may have a material adverse effect on SanTi's
business, results of operation and financial condition.

     SanTi will be at a disadvantage in competing against service providers that
are better capitalized, have greater name recognition, have more background and
experience, have greater financial, technical, marketing and other resources and
skills, have better facilities and are able to provide services or products at a
lower cost than SanTi. Because the NLW industry is currently highly fragmented,
the acquisition of local NLW service providers is the only strategy by which
SanTi may be able to penetrate existing markets. As a result of these
competitive factors, there can be no assurance that SanTi's growth strategy will
be successful or that SanTi will be able to generate cash flow adequate for its
operations and to support future acquisitions and internal growth.

Employees

     As of August 28, 1998, SanTi had 290 employees. It is anticipated that the
acquisition and integration of additional NLW service providers will add
employees as acquisitions are made but that the number of employees in acquired
businesses may be reduced as duplicate administrative processes are eliminated.


                                      -7-

Government Regulations

     SanTi is subject to rules and regulations of various federal, state and
local governmental agencies. Environmental laws and regulations are, and will
continue to be, a principal factor affecting the marketability of the services
provided by SanTi. Any changes in these laws or regulations may affect the
operations of SanTi by imposing additional regulatory compliance costs on SanTi,
requiring the modification of or adversely affecting the market for SanTi's NLW
services. To the extent that demand for these services is based upon the need to
comply with these regulations, any modification to these regulations may
increase the cost of or decrease the demand for these services and adversely
affect SanTi's business condition and results of operations.

     Additionally, if new environmental legislation or regulations are enacted
or existing legislation or regulations are amended or enforced differently,
SanTi may be required to obtain additional operating permits, registrations or
approvals. The process of obtaining a required permit, registration or approval
can be lengthy and expensive and the issuance of such permit or the obtaining of
such approval may be subject to public opposition. There can be no assurance
that SanTi will be able to meet the applicable regulatory requirements.

     Resource Conservation and Recovery Act ("RCRA"). RCRA is the principal
federal statute governing hazardous and solid waste generation, treatment,
storage and disposal. RCRA and state hazardous waste management programs govern
the handling and disposal of "hazardous waste." The U.S. Environmental
Protection Agency ("EPA") has issued regulations pursuant to RCRA. States have
also promulgated regulations under comparable state statutes that govern
hazardous waste generators, transporters and owners and operators of hazardous
waste treatment, storage and disposal facilities. These regulations impose
detailed operating, inspection, training and emergency preparedness and response
standards and requirements for the financial responsibility, manifesting of
wastes, record keeping and reporting, as well as treatment standards for any
hazardous wastes intended for land disposal.

     NLW is currently exempt from the requirements of RCRA. The repeal or
modification of the RCRA exemption covering NLW, or the modification of
applicable regulations or interpretations regarding the treatment or disposal of
NLW, may require SanTi to alter its method of treating and disposing of NLW.
SanTi's current methods do not comply with the methods prescribed by the EPA for
treatment and/or disposal of waste as defined by RCRA. These changes may result
in decreased demand for SanTi's services or increased costs to SanTi and could
have a material adverse effect on SanTi's business.

     Comprehensive Environmental Response, Competition and Liability Act
("CERCLA"). CERCLA provides for immediate response and removal actions
coordinated by the EPA for releases of hazardous substances into the environment
and authorizes the government or private parties to respond to the release or
threatened release of hazardous substances. The government may also order
persons responsible for the release to perform any necessary cleanup. Liability
extends to the present owners and operators of waste disposal facilities from
which a release occurs, persons who owned or operated the facilities at the time
the substance was released, persons who arranged for the disposal or treatment
of hazardous substances and waste transporters who selected such facilities for
treatment or disposal of hazardous substances. CERCLA creates strict, joint and
several liability for all costs of removal and remediation, other necessary
response costs and damages for injury to natural resources.

     As SanTi will be engaged in businesses that involve the treatment and
removal of nonhazardous liquid waste, SanTi should not be subject to CERCLA.
However, if SanTi were to acquire a business that has disposed of hazardous
waste or treated hazardous waste that falls within the parameters of CERCLA,
SanTi may be held jointly and severally liable for the costs of any damage or
required cleanup of the site.

The following table sets forth selected financial data of the Company. The
selected financial data for the period from inception (March 19, 1997) to
December 31, 1997 are derived from the audited financial statements of the
Company, and the selected financial data for the years ended December 31, 1995
and 1996 and for the period from January 1, 1997 to December 21, 1997 are
derived from the audited financial statements of the Predecessor, Andrews
Environmental Services, Inc. The selected financial data for the six month
period ended June 30, 1998 are derived from the unaudited financial statements
of the Company. The selected financial data for the years ended December 31,
1993 and 1994 and for the three month period ended March 31, 1997 are derived
from the unaudited financial statements of the Predecessor. As a result of

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

     The following discussion contains trend information and other forward
looking statements that involve a number of risks and uncertainties. SanTi's
actual future results could differ materially from its historical results of
operations and those discussed in the forward looking statements. Certain of the
risks and uncertainties are set forth below. The following should be read in
conjunction with the Company's financial statements and the notes thereto
included elsewhere herein.

Overview

     SanTi engages in businesses relating to the NLW industry. These businesses
include grease trap pumping, septic tank services (including designing, pumping,
installation and maintenance), sewer and drain cleaning services; high pressure
jetting services, portable toilet servicing; bulk liquid waste transportation;
on-site biotreatment systems; biosolids management; and liquid waste processing
and disposal. The customers of SanTi include restaurants, hospitals, military
bases, office buildings, apartments, schools, municipalities, industrial
businesses and single family residences.

     SanTi intends to expand its business in the NLW industry through internal
growth and the acquisition of local service providers throughout the United
States. These acquisitions will be made with cash, shares of Common Stock or a
combination of cash and Common Stock. SanTi's strategy is to increase the
efficiency and profitability of each of the acquisition targets through
operational and marketing synergies with SanTi's existing business operations.

     The NLW industry serves a basic need - the collection, treatment and
disposal of food and septic waste. Demand for NLW services is driven primarily
by population and the general level of economic activity. Increasing regulation
at the federal, state and local level, as well as increased awareness of and
demand for, a safer and cleaner environment, are creating the need for a more
professional and environmentally responsible NLW industry.

Trends

   In addition to the factors discussed above, the following are important
factors which could cause actual results or events to differ materially from
those contained in any forward looking statement made by or on behalf of SanTi.

AVAILABILITY OF ACQUISITION FINANCING. The ability of SanTi to acquire local NLW
service providers at economically attractive prices, integrate their operations
into SanTi, and then grow their operations profitably, will determine the
success of SanTi. SanTi's ability to acquire these providers will depend on the
availability of capital. The consideration for these acquisitions will be cash,
Common Stock or a combination of Common Stock and cash. If the Common Stock does
not retain a sufficient value or potential acquisition candidates are unwilling
to accept Common Stock as consideration, SanTi will be required to use its cash
resources to purchase these providers. If the current capital resources are
exhausted, SanTi may not be able to access additional financing and may be
limited in its ability to continue its acquisition strategy.

OPERATING STRATEGY. SanTi's ability to increase revenues of its existing
operations and its acquired service providers will be affected by various
factors, including: customer demand for NLW treatment and disposal services by
SanTi, SanTi's ability to expand the range of services offered to customers and
SanTi's ability to develop national and regional accounts for its services and
other marketing programs necessary to attract new customers and attract and
retain necessary personnel. There can be no assurance that SanTi's operating
strategy will be successful or that SanTi will be able to generate cash flows
adequate to support its operations and internal growth.


                                      -10-
<PAGE>   11
 
GOVERNMENTAL REGULATIONS. As discussed previously, the NLW industry is subject
to numerous federal, state and local laws and regulations relating to
environmental concerns. Any changes in these laws or regulations may affect the
operation of SanTi by imposing additional regulatory compliance costs on SanTi,
requiring the modification of or adversely affecting the market for SanTi's NLW
treatment services. To the extent that demand for these services is based upon
the need to comply with these regulations, any modification to these regulations
may decrease the demand for these services and adversely affect SanTi's business
or results of operations.

Forward Looking Statements

     Forward looking statements contained in this Form 10 involve risks and
uncertainties, including, without limitation, the following: (i) SanTi's
strategies, objectives, expectations and intentions are subject to change at any
time at the discretion of management and the Board of Directors, (ii) SanTi's
plans and results of operations will be affected by SanTi's ability to manage
its growth and access to capital, and (iii) SanTi's business is highly
competitive and the entrance of new competitors or the expansion of operations
by existing competitors in SanTi's markets could adversely affect SanTi's plans
and results of operations.

General

     The Company derives the majority of its revenues from commercial and
residential septic services (including designing, pumping, installation and
maintenance) (approximately 59% of current revenues) and to a lesser extent
sewer and drain services (approximately 20% of current revenues). Collection
fees charged to customers vary per gallon by waste stream according to
constituents of the waste, expenses associated with processing the waste and
competitive factors. Cost of operations consist of fixed costs such as salaries
and benefits of vehicle operators and construction labor and variable costs such
as supplies, fuel and equipment rentals. General and administrative costs
consist primarily of compensation and related benefits for executives and
administrative staff, advertising, office rent, communications and professional
fees. Depreciation and amortization expense primarily relates to the
depreciation of capital assets, the amortization of excess cost over the fair
value of net assets acquired (goodwill) and other intangible assets. The
Company's policy is to amortize goodwill over a 40 year life.

     From its inception on March 19, 1997 through August 28, 1998, the Company
has acquired nine businesses, all of which were accounted for using the purchase
method of accounting. Prior to their acquisition by the Company, the acquired
businesses were managed as independent private businesses, and their results of
operations reflect different tax structures (S corporations and C corporations),
which have influenced, among other things, their historical levels of owners'
compensation. Certain owners who continued employment with the Company agreed to
reductions in their compensation and benefits in connection with the acquisition
of their businesses by the Company.

     In connection with each of its acquisitions, the Company attempts to
implement a number of cost saving measures, including possible reductions in
management levels and other personnel, the implementation of centralized
management and cost controls and the elimination of duplicate collection routes.

RESULTS OF OPERATIONS

     On March 20, 1997, the Company purchased certain assets of Andrews
associated with the Andrews grease disposal business. On December 22, 1997, the
Company acquired the remaining assets and ongoing business of Andrews. For
financial reporting purposes Andrews is considered the predecessor to the
Company (the "Predecessor"). As a result of the Company's recent acquisitions
and the limited period of ownership of the acquired businesses, the Company
believes that the period-to-period comparisons and percentage relationships
within the periods set forth below are not meaningful.

SIX MONTHS ENDED JUNE 30, 1998

   
   For the six months ended June 30, 1998, the Company reported a loss of
$1,542,310 on revenues of $9,947,494. A discussion from the date of inception
(March 19, 1997) to June 30, 1997 has not been presented because the data is
not meaningful.
    

   The Company completed four acquisitions during the first quarter of 1998 and
two acquisitions during the second quarter of 1998. In January 1998, the Company
acquired Ferrero, located in Ambler, Pennsylvania. In February 1998, the
Company acquired A Rapid located in Pompano Beach, Florida, and Quality located
in Douglasville, Georgia. In March 1998, the Company acquired Seagraves located
in Orlando, Florida. In May 1998, the Company acquired RGM, located in Deer
Park, New York, and Eldridge, located in West Chester, Pennsylvania. All
acquisitions have been accounted for using purchase accounting and the results
of operations of the acquired businesses have been included in the Company's
consolidated financial statements from the date of each acquisition.

   
REVENUES: Revenues for the six months consist of revenues from each of the
businesses acquired in 1997 plus revenues from businesses acquired during the
first two quarters of 1998, from the date of each acquisition. The six completed
acquisitions contributed approximately $9.0 million or 91% of revenues for the
six months ended June 30, 1998.
    

   
COST OF OPERATIONS: The operating margin for the six months ended June 30, 1998
was 27%. 
    


GENERAL AND ADMINISTRATIVE: General and administrative expense has been and is
projected to be a significant percentage of revenue in the Company's early
stages of growth. Management anticipates that as revenue increases through
acquisitions, general and administrative expenses will increase in total, but
decrease as a percentage of



                                      -12-
<PAGE>   13
   
revenue. For the six months ended June 30, 1998, general and administrative
expense includes non-recurring expenses associated with the relocation of the
corporate headquarters to Dallas, Texas; expenses associated with registering
the Company as a reporting company with the Securities and Exchange Commission;
and costs associated with the establishment of the Company's management team.

DEPRECIATION AND AMORTIZATION: Depreciation and amortization was $517,904 or
5% of revenues for the six months ended June 30, 1998.

LOSS FROM OPERATIONS: The loss from operations is primarily the result of the
high level of general and administrative expense.

INTEREST EXPENSE: Interest expense for the six months ended June 30, 1998
was $274,042. Interest was incurred at an average rate of approximately 7.7%
during the six months ended June 30, 1998.
    

INCOME TAX BENEFIT: An income tax benefit of 39% of pretax loss has been
computed in accordance with SFAS No. 109 "Accounting for Income Taxes." The tax
benefit has been offset by a valuation allowance of $384,367. Realization of the
net tax benefit is dependent on the Company generating sufficient taxable income
in future periods. Although realization is not assured, management believes it
is more likely than not that the Company will generate taxable income in future
periods to permit usage of the estimated net operating loss carry forward. To
date, all acquisitions have been taxable asset purchases in which the Company
obtained a full basis in acquired tangible and intangible assets. To the extent
the Company makes future nontaxable acquisitions, the Company's effective rate
may differ significantly from its statutory rate due to nondeductible goodwill
amortization.

PERIOD FROM INCEPTION (MARCH 19, 1997) TO DECEMBER 31, 1997

     The financial statements of the Company for the period from inception
(March 19, 1997) to December 31, 1997 reflect a net loss of $258,352 on revenues
of $737,858.

     The Company completed three acquisitions in 1997: the grease division of
Andrews in March 1997, Atlanta Grease Trap in August 1997 and the remaining
assets of Andrews in December 1997. All three acquisitions have been accounted
for using purchase accounting and the results of operations of the acquired
businesses have been included in the consolidated financial statements from the
date of each acquisition.

REVENUES: Revenues for period from inception (March 19, 1997) to December 31,
1997 consist of revenues from each of the businesses acquired from the date of
each acquisition.

COST OF OPERATIONS: The operating margin was 45%.

GENERAL AND ADMINISTRATIVE: General and administrative expense has been and is
projected to be a significant percentage of revenues in the early stages of the
Company's growth. It is anticipated that as revenues grow from future
acquisitions, that general and administrative expense as a percentage of revenue
will decline. The amounts reported for general and administrative expense
include a number of costs associated with establishing the Company and hiring
employees.

DEPRECIATION AND AMORTIZATION: Depreciation and amortization was $127,338 or
17% revenues.

LOSS FROM OPERATIONS: The loss from operations is due primarily to the high
level of general and administrative expense as a percentage of revenue.

INTEREST EXPENSE: Interest expense of $104,494 was based on an average interest
rate of 13% over the period.


                                      -13-
<PAGE>   14
INCOME TAX BENEFIT: An income tax benefit of 39% of pretax loss was recorded for
the period from inception (March 19, 1997) to December 31, 1997.

PERIOD FROM JANUARY 1, 1997 TO DECEMBER 21, 1997 COMPARED TO YEAR ENDED DECEMBER
31, 1996

REVENUES: Revenues decreased 34% to $1,218,268 in 1997 from $1,832,043 in 1996.
This decrease was primarily due to the sale of the Grease Business to SanTi in
March 1997.

COST OF OPERATIONS: Cost of operations decreased 20% to $625,892 in 1997 from
$785,996 in 1996. Cost of operations as a percentage of revenues increased to
51% in 1997 from 43% in 1996. The increase in cost of operations as a percentage
of revenues was due to the sale of the more profitable grease business in March
1997.

GENERAL AND ADMINISTRATIVE: General and administrative expense decreased to
$646,273 in 1997 from $757,655 in 1996, a decrease of 15%. The decrease in
general and administrative was a result of the sale of the grease business. As a
percentage of sales, general and administrative increased to 53% in 1997 from
41% in 1996. This increase occurred because certain general and administrative
expenses which supported both the grease business and the continuing business of
Andrews were relatively fixed in nature, and were not decreased as a result of
the sale of the grease business.

   
DEPRECIATION AND AMORTIZATION: Depreciation and amortization remained relatively
constant, at approximately $122,000. The disposition of assets associated with
the grease business did not significantly effect depreciation, because the
majority of the assets sold had been fully depreciated.
    

LOSS (INCOME) FROM OPERATIONS: The loss from operations of $175,393 for 1997, as
compared to income from operations of $166,096 in 1996, was primarily due to the
loss of revenue from the sale of the grease business and the inability to reduce
expenses to the extent that revenue was diminished.

INTEREST EXPENSE: Interest expense decreased from $70,868 in 1996 to $22,077 in
1997, due to decreased capital expenditures in 1997, and the decrease in debt
and interest payments associated with certain assets sold in conjunction with
the grease business.

OTHER, NET: Other, net includes a gain on sale of assets of approximately
$240,000 recorded in connection with the sale of the grease business.

PROVISION FOR INCOME TAXES: The effective tax rate increased from 40% in 1996 to
65% in 1997 due to the low level of income in 1997 and the relatively fixed
nature of certain items which are not deductible for tax purposes.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

REVENUES: Revenues increased 22.2% to $1,832,043 in 1996 from $1,499,392 in
1995. The increase was due to internal growth of the business.

COST OF OPERATIONS: Cost of operations increased 28% to $785,996 in 1996 from
$615,069 in 1995. The increase was a result of the higher level of revenue. Cost
of operations as a percentage of revenues increased to 43% in 1996 from 41% in
1995. The percentage increase was driven by additional overtime labor incurred
to generate a portion of the additional revenue.

GENERAL AND ADMINISTRATIVE: General and administrative expense remained
relatively stable at $757,655 in 1996 and $754,580 in 1995. General and
administrative expenses have historically been a significant percentage of
revenues and relatively fixed in nature.

DEPRECIATION AND AMORTIZATION: Depreciation and amortization increased to
$122,296 in 1996 from $94,948 in 1995. This is primarily due to acquisitions of
property and equipment during 1996 and 1995.


                                      -14-
<PAGE>   15

INCOME FROM OPERATIONS: The increase of income from operations from 1995 to 1996
of $131,310 was primarily due to the growth of the business and Andrew's ability
to maintain general and administrative expenses at a relatively stable level.

INTEREST EXPENSE: Interest expense increased from $45,475 in 1995 to $70,868 in
1996, due to the financing of capital expenditures in 1996 and late 1995.

PROVISION (BENEFIT) FOR INCOME TAXES: The effective tax rate changed from a
benefit of (19)% in 1995 to a provision of 40.0% in 1996 due to the low level
of income in 1995 and the relatively fixed nature of certain items which are not
deductible for tax purposes.

SEASONALITY AND INFLATION

   The Company's operations are affected by the weather. Rainy weather requires
more frequent septic and grease trap maintenance and snow cover or frozen
conditions prevent installation and need for servicing septic systems. Although
the Company experiences a certain degree of seasonality in its operations due to
weather, this seasonality is lessened through its operations in various
geographic areas.

   The Company believes that inflation and changing prices have not had, and are
not expected to have, any material adverse effect on its results of operations
in the near future.

   
LIQUIDITY AND CAPITAL RESOURCES

   At June 30, 1998, the Company had cash of approximately $2.9 million and
working capital of $1.7 million.
    

   
    On June 26, 1998, the Company entered into the $40 million revolving Credit
Agreement with Bank of America, which was amended as of June 30, 1998. The
Company may also obtain up to $5 million in letters of credit, subject to
availability under the Credit Agreement. Interest is payable monthly at variable
rates, depending on the Company's Funded Debt to EBITDA (as defined in the
Credit Agreement), but is capped at Libor plus 2.25%. The Credit Agreement
expires June 26, 2001, is secured by a first lien on substantially all assets of
the Company and requires the Company to maintain certain financial covenants
beginning June 30, 1998. The financial ratio covenants are (i) Minimum Net Worth
($18.0 million), (ii) EBIT to Interest Coverage (1.5:1.0); (iii) Funded Debt to
EBITDA (4.0:1.0) and (iv) Debt to Capitalization (65%). As of June 30, 1998, the
Company was in compliance with these financial covenants. In connection with
entering into the Credit Agreement, two existing lines of credit (the "Prior
Credit Facilities") with availability of $16.6 million were repaid and
canceled. 
    

   
    The Company's primary requirements for capital (other than those related to
acquisitions) consist of purchasing vehicles and equipment used in the operation
of its businesses. During the six months ended June 30, 1998, the Company made
$330,570 in capital expenditures. From March 19, 1997 (inception) through July
20, 1998, the Company acquired nine businesses for an aggregate consideration of
$19.8 million in cash, $2.3 million in seller notes and 471,400 shares of Common
Stock. In addition to the above amounts, the acquisition agreements include
contingent consideration totaling $1,608,900 in cash and 93,600 shares of Common
Stock. Funding of the cash portions of the purchase prices was provided by
borrowings under the Prior Credit Facilities and proceeds from private sales of
Common Stock. From March 19, 1997(inception) through June 30, 1998, the Company
received approximately $16.3 million in proceeds from private sales of Common
Stock. The Company believes that funds provided by operations, together with
cash on hand and funds available under the Credit Agreement, will be adequate to
meet the Company's anticipated capital expenditures for the remainder of 1998.

    

   The Company intends to aggressively pursue internal growth and acquisition
opportunities. The timing, size or success of any acquisitions effort and the
associated potential capital commitments are unpredictable. The Company expects
to fund future acquisitions primarily through a combination of cash on hand,
borrowings from the unborrowed portion of the Credit Agreement and the possible
public or private sale of debt and equity securities.

YEAR 2000

   
The Company has conducted operations for less than two years and has only
recently grown large enough to require sophisticated computing systems. A
complete review of all of the Company's computing needs has recently been
undertaken. The Company has completed its review, including various Year 2000
compliant computer programs, and has selected Year 2000 compliant hardware and
software for its computing needs. The Company anticipates beginning
implementation of these new systems during the third quarter of 1998, which
implementation should ensure proper processing of transactions relating to the
Year 2000 and beyond. The Company expects the conversion of all systems to be
completed in the first quarter of 1999 and estimates the capital costs of the
new Year 2000 compliant hardware, systems and software to be approximately
$250,000.
    

   
   The Year 2000 issue is expected to affect the systems of various entities
with which the Company interacts, including the Company's vendors and customers.
There can be no assurance that the systems of other companies on which the
Company's systems rely will be timely converted or that a failure by another
company's systems to be Year 2000 compliant would not have a material adverse
effect on the Company.

Corporation Law of the State of Delaware (or the corresponding provision of any
successor law or act), and (iv) for any transaction from which the director
derived an improper personal benefit.

or director who was or is a party to, or is threatened to be made a party to,
any threatened, pending or completed action, suit or proceeding, including
civil, criminal, administrative, investigative or otherwise, by reason of the
fact that such person is or was a director or officer of SanTi, or is or was
acting at the request of SanTi as a director, officer, partner, trustee,
employee or agent of another corporation, partnership, joint venture, trust,

reductions in salaries and certain benefits to the owners. To the extent the
owners of the Acquired Businesses have agreed prospectively to reductions in
salary, bonuses and benefits, these reductions have been reflected in the pro
forma combined statements of operations. With respect to other potential cost
savings, SanTi cannot fully quantify these savings at this time. It is
anticipated that these savings will be partially offset by costs related to
SanTi's corporate management and by the costs associated with being a public
company. These costs cannot be quantified accurately. Accordingly, only those
anticipated savings and costs that are factually supportable have been included
in the accompanying pro forma financial information of the Company.

The pro forma adjustments are based on estimates, available information and
certain assumptions and may be revised as additional information becomes
available. The pro forma financial data do not purport to represent what SanTi's
results of operations would actually have been if such transactions in fact had
occurred on those dates and are not necessarily representative of the SanTi
results of operations for any future period. Since the Acquired Businesses were
not under common control or management, historical combined results may not be
comparable to, or indicative of, future performance. The unaudited pro forma
combined financial statements should be read in conjunction with the historical
financial statements and notes thereto included elsewhere herein. Also see "Risk
Factors".

                    SANTI GROUP, INC. AND ACQUIRED BUSINESSES
           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
                      JUNE 30, 1998 AND DECEMBER 31, 1997
    


1. BACKGROUND

SanTi Group, Inc. ("SanTi") was formed to act as a consolidator of nonharzardous
liquid waste businesses. From its inception on March 19, 1997 through May 8,
1998, SanTi has acquired nine businesses involved in the nonhazardous liquid
waste business ("Acquired Businesses").

   
2. HISTORICAL FINANCIAL STATEMENTS

The historical financial statements of the Acquired Businesses were derived from
the respective Acquired Businesses' financial statements. All Acquired
Businesses have a December 31 year-end, or their financial results have been
recast to a December 31 year-end, with the exception of RGM which has an October
31 year-end. The audited historical financial statements included elsewhere in
this Registration Statement have been included in accordance with Securities and
Exchange Commission (SEC) Staff Accounting Bulletin No. 80.
    

3. ACQUISITION OF ACQUIRED BUSINESSES

The acquisitions of the Acquired Businesses were financed by borrowings under
two credit agreements with total availability of $16.6 million and cash proceeds
of $16.3 million from sales of common stock. All acquisitions have been
accounted for using the purchase method of accounting.

The following table sets forth the consideration paid in (a) cash, (b) seller
notes and (c) value of common stock to the shareholders of the Acquired
Businesses:

In addition to the above amounts, the agreements include contingent
consideration totaling $1,608,900 in cash and 93,600 shares of common stock.
These amounts are payable by the Company to the Acquired Businesses on various
dates specified by the agreements, contingent upon the meeting of certain goals
as defined in the agreements. For purposes of computing the estimated purchase
price for accounting purposes, the value of the common stock was determined
using an estimated fair value of $.80 - $1 per share for all acquisitions except
for RGM and Eldredge, for which the common stock was valued at $5.80 per share.
These per share prices are based on the offering prices of the Company's common
stock issued in private transactions occurring in January and April of 1998.

   
Based upon management's analysis of fair value, the historical carrying value of
the acquired assets approximates fair value, with the exception of property and
equipment, for which the carrying value has been increased by approximately
$800,000. The amount allocated to noncompete agreements and goodwill is
approximately $1.2 million and $17.2 million, respectively. Management of SanTi
has not identified any other material tangible or identifiable intangible assets
of the Acquired Businesses to which a portion of the purchase prices could
reasonably be allocated.
    

4. RECAPITALIZATION

On May 13, 1998 SanTi merged ("Merger") with Microlytics, Inc. ("Microlytics").
Under the terms of the Merger each outstanding share of SanTi common stock was
exchanged for one share of Microlytics common stock. Immediately prior to the
merger, Microlytics had 1,027,066 shares of common stock outstanding and
warrants to purchase an additional 500,000 shares of common stock at an exercise
price of $5.80. The Merger resulted in the receipt by Santi shareholders of
approximately 8,088,379 shares of common stock, representing approximately 86.2%
of the Microlytics shares outstanding on the effective date of the Merger. As a
result of the Merger, SanTi Group, Inc. was merged into Microlytics and
Microlytics certificate of incorporation was amended as of the effective date of
the Merger to change Microlytics' name to SanTi Group, Inc. For accounting
purposes, the Merger has been accounted for as a capital transaction accompanied
by a recapitalization of SanTi.

5. UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS ADJUSTMENTS:

(a) Reflects additional amortization of noncompete agreements using a weighted
average life of 2.2 years and goodwill using a 40 year life. Also includes
additional depreciation of property and equipment using a weighted average
remaining life of 5 years.

(b) Reflects additional interest expense on the $2.3 million in seller notes at
a weighted average annual rate of 6.2%.

(c) Reflects elimination of interest expense of Acquired Businesses net of
additional interest expense on $3.9 million in line of credit borrowings at
8.21%. The elimination of interest expense of the acquired businesses is
required as the Company assumed no debt in the purchase transactions. Additional
borrowings under the Company's line of credit of $3.9 million were required to
supplement equity proceeds from the sale of common stock to pay the cash portion
of the purchase prices.

(d) Adjusts compensation to the level that the owners of the Acquired Businesses
have contractually agreed to receive subsequent to the Acquisitions. The
employment agreements have terms of one to three years and include certain
severance provisions in the event of termination without cause.

   
(e) Reflects additional income tax provision (benefit) for state and federal
taxes at a combined statutory tax rate of 39% as certain Acquired Businesses
previously were taxed as Subchapter S Corporations.
    

   
(f) Reflects (benefit) for income taxes using the Company's combined statutory
tax rate of 39% for the tax effect of adjustments (a) thru (d).

To SanTi Group, Inc.:


   
We have audited the accompanying consolidated balance sheet of SANTI GROUP, INC.
(a Delaware corporation) AND SUBSIDIARIES as of December 31, 1997 and the

financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
    

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of SanTi Group, Inc. and

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
   
                DECEMBER 31, 1997 AND JUNE 30, 1998 (UNAUDITED)

    

1.       ORGANIZATION AND BASIS OF PRESENTATION

         SanTi Group, Inc. ("SanTi" or the "Company") was incorporated on August
         19, 1997 as a Delaware corporation. The Company operates as a
         consolidator of the highly fragmented nonhazardous liquid waste
         management industry through acquisition of businesses with operating
         service centers that treat, process, and recover nonhazardous liquid
         waste to serve a variety of customers from private residences and
         municipalities to large industrial companies.

         Bone-Dry Enterprises, Inc. ("Bone-Dry") was incorporated on March 19,
         1997 as a Georgia corporation. On December 1, 1997, all shares of
         Bone-Dry common stock were exchanged for SanTi common stock. Since the
         Company and Bone-Dry were under common ownership since their respective
         dates of inception, the accompanying financial statements are for the
         period from the inception of Bone Dry (March 19, 1997) to December 31,
         1997. The accompanying consolidated financial statements include the
         accounts of the Company and its wholly owned subsidiaries. All material
         intercompany balances and transactions have been eliminated.


2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         CASH AND CASH EQUIVALENTS

         The Company considers all highly liquid investments with maturities of
         three months or less at the date of purchase as cash equivalents.
   
    
         MACHINERY AND EQUIPMENT

         Machinery and equipment are recorded at cost. Depreciation is provided
         over the estimated useful lives of the assets using the straight-line
         method. The estimated useful lives for machinery and equipment range
         from five to seven years.

         INTANGIBLES

         As of December 31, 1997, intangibles consist primarily of goodwill of
         $1,214,228 and noncompete agreements of $259,261 associated with
         business acquisitions. Noncompete agreements are being amortized over
         the lives of the

                                      F-15
<PAGE>   42


         contracts. Goodwill is being amortized over 40 years. Amortization 
         expense associated with intangibles was $95,464 for the period from 
         inception (March 19, 1997) to December 31, 1997.

         REVENUE RECOGNITION

         The Company recognizes revenues as services are provided.

         LONG-LIVED ASSETS

   
         The Company periodically reviews the values assigned to long-lived
         assets, such as property and equipment and intangibles, to determine
         whether any impairments are other than temporary. The Company assesses
         impairment by determining whether the carrying value of such long-lived
         assets will be recovered through undiscounted expected future cash
         flows. No impairment losses have been recorded during the period from
         inception (March 19, 1997) to December 31, 1997. 
    

         EARNINGS PER SHARE

         Basic earnings per share are based on the weighted average number of
         shares outstanding. Diluted earnings per share are based on the
         weighted average number of shares outstanding and the dilutive effect
         of stock options outstanding (using the treasury stock method) and
         contingently issuable shares. For the period from inception (March 19,
         1997) to December 31, 1997, outstanding options of 612,500 and
         contingently issuable shares have been excluded from diluted weighted
         average shares outstanding, as their impact was antidilutive.

         USE OF ESTIMATES

         The preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities and disclosure of contingent assets and liabilities at the
         date of the financial statements and the reported amounts of revenues
         and expenses during the reporting period. Actual results could differ
         from those estimates.

         UNAUDITED INTERIM FINANCIAL INFORMATION

   
         The accompanying financial statements as of June 30, 1998, for the
         period from inception (March 19, 1997) to June 30, 1997 and for the six
         month period ended June 30, 1998, are unaudited. In the opinion of
         management, these financial statements reflect all adjustments,
         consisting only of normal recurring adjustments, necessary for a fair
         presentation of the financial statements. The results of operations for
         the six month period ended June 30, 1998 are not necessarily indicative
         of the results that may be expected for the full year.
    

         NEW ACCOUNTING PRONOUNCEMENTS

         In June 1997, the Financial Accounting Standards Board (the "FASB")
         issued Statement of Financial Accounting Standards ("SFAS") No. 130, 
         "Reporting Comprehensive Income."  SFAS No. 130 is designed to improve
         the reporting of changes in equity from period to period.  The Company
         currently has no other comprehensive income items as defined by SFAS
         No. 130.

         In June 1997, the FASB issued SFAS No. 131, "Disclosures About
         Segments of an Enterprise and Related Information."  SFAS No. 131
         requires that an enterprise disclose certain information about
         operating segments.  SFAS No. 131 is effective for financial
         statements for the Company's fiscal year ending December 31, 1998.
         The Company does not expect that SFAS No. 131 will require revision of
         prior disclosures.

3.       ACQUISITIONS

         On March 20, 1997, Bone-Dry purchased certain assets of Andrews
         Environmental Services, Inc. ("Andrews") associated with Andrews Grease
         Disposal Business ("Andrews Grease"). Andrews Grease is in the business
         of commercial and governmental grease 


                                      F-16
<PAGE>   43


         extraction, collection, and transportation services primarily in the
         state of Georgia. Consideration associated with the purchase was
         $475,000 in cash and $257,350 in notes payable.

         On August 27, 1997, Bone-Dry purchased Atlanta Grease Trap Service
         ("Atlanta Grease"), a Georgia sole proprietorship, for $360,000 in
         cash. Atlanta Grease is in the business of commercial and governmental
         grease extraction, collection, and transportation services in the state
         of Georgia.

         On December 22, 1997, Bone-Dry purchased substantially all of the
         remaining assets of Andrews. Andrews is engaged in the nonhazardous
         liquid waste and septic waste collection, transportation, management,
         and disposal business primarily in the state of Georgia. Consideration
         associated with the purchase was $660,000 in cash and 21,400 shares of
         SanTi common stock. Contingent consideration of 13,600 shares of SanTi
         common stock is payable within 90 days of the first anniversary of the
         date of purchase, net of offsets for losses, as defined in the purchase
         agreement.

         The acquisitions of Andrews Grease, Atlanta Grease, and Andrews were
         accounted for using the purchase method of accounting; accordingly, the
         purchase prices have been allocated to the assets acquired based on
         their respective fair values at the dates of acquisition. The resulting
         excess of purchase prices over fair values of assets acquired was
         recorded as goodwill. Goodwill recorded in the purchases of Andrews
         Grease, Atlanta Grease, and Andrews was $482,350, $360,000, and
         $349,136, respectively.

         The Company's unaudited pro forma consolidated results of operations
         for the period from inception (March 19, 1997) to December 31, 1997
         shown below are presented assuming that the December 22, 1997
         acquisition of Andrews had been consummated on March 19, 1997:

<TABLE>
                  <S>                                 <C>
                  Pro forma revenue                   $1,778,126
                  Pro forma net (loss)                  (256,113)
                  Pro forma (loss) per share          $     (.27)
</TABLE>

         The Company's unaudited pro forma results of operations are presented
         for informational purposes only and may not necessarily reflect the
         future results of operations of the Company or what the results of
         operations would have been had the Company owned and operated Andrews
         as of March 19, 1997. The Company's acquisition of Atlanta Grease is
         not significant for purposes of presenting pro forma information.

         Subsequent to year-end, the Company acquired the following businesses:

                  -        On January 22, 1998, the Company purchased Ferrero

         finance the Company's acquisitions of businesses discussed in Note 3.
         In June 1998, the lines of credit were paid in full in conjunction with
         the Company obtaining new financing from another bank (Note 10).

6.       RELATED-PARTY TRANSACTIONS

         In 1997, the Company entered into a note payable agreement with an
         entity controlled by the Company's majority owner. The note was for
         $650,000, had an interest rate of 13%, and was paid in full during
         1997. In December 1997, after the note was paid in full, the related
         party purchased 1,608,750 shares of SanTi common stock for $650,000.

         In March 1997, the Company entered into a four-year consulting
         agreement with a former owner of an acquired business. The Company paid
         its obligation of $75,000 in full during 1997, as required by the
         agreement, and is recognizing the expense over the life of the
         agreement. For the period from inception (March 19, 1997) to December
         31, 1997, consulting expense related to the agreement was $13,021 and
         is included in general and administrative expenses in the accompanying
         statement of operations.

         During 1997, the Company entered into three noncompete agreements with
         former owners of acquired businesses in exchange for notes payable
         totaling $341,130. In connection with the December 22, 1997 purchase of
         Andrews, one of the former owners of Andrews exchanged $263,685 of
         outstanding notes payable, issued in connection with the March 1997
         purchase of Andrews Grease, for 14,479 shares of SanTi common stock.

         LEASES

         The Company leases office space and equipment from an entity controlled
         by the Company's majority owner under a lease agreement which expires
         January 31, 1998 and is renewable for successive one-month periods.
         Rental expense under the lease was $11,690 for the period from
         inception (March 19, 1997) to December 31, 1997.

7.       STOCK-BASED COMPENSATION

         In August 1997 and December 1997, the Company issued nonqualified stock
         options to purchase 125,000 and 487,500 SanTi common stock,
         respectively, at $.65 per share, which represented the fair market
         value as of the dates of grant as determined by the Company's board of
         directors. The options are exercisable for a period of three years
         beginning on the dates of grant. See Note 10 where exercised
         subsequent to year end.

         The Company has adopted the disclosure-only provisions of SFAS No. 123,
         "Accounting for Stock-Based Compensation." Accordingly, no compensation
         cost has been recognized for the stock options granted. Had
         compensation cost for the Company's stock options granted been
         determined consistent with the provisions of SFAS No. 123, the
         Company's net loss would have been increased to the pro forma amount
         indicated below for the period from inception (March 19, 1997) to
         December 31, 1997.

<TABLE>
                           <S>                                 <C>

                           Pro forma net (loss) per share             (.35)
</TABLE>

         The fair values of options granted were estimated on the date of grant
         using the minimum value approach, an expected life of three years, and
         risk-free interest rate of 5.88%.

8.       INCOME TAXES

         The accompanying financial statements include an income tax benefit
         computed in accordance with SFAS No. 109, "Accounting for Income

</TABLE>

         As of December 31, 1997, deferred tax assets include a net operating
         loss carryforward of $275,566 which is available to offset future
         taxable income through 2012. Realization of the net deferred tax asset
         is dependent on generating sufficient taxable income in future periods.
         Although realization is not assured, management believes it is more
         likely than not that the net deferred tax asset will be realized.

9.       ENVIRONMENTAL REGULATIONS

         The Company is subject to extensive and evolving federal, state, and
         local environmental laws and regulations that have been enacted in
         response to technological advances and the public's increased concern
         over environmental issues. The majority of the expenditures necessary
         to comply with the environmental laws and regulations is made in the
         normal course of business. The Company, to the best of its knowledge,
         is in compliance, in all material respects, with the laws and
         regulations affecting its operations.

10.      SUBSEQUENT EVENTS

         On January 12, 1998, a group of investors purchased 1,250,000 shares of
         the Company's common stock for $.80 per share.

         On January 30, 1998, the Company declared a 1.25-for-1 stock split
         effected in the form of a stock dividend. All share amounts have been
         restated for this stock split.

         During March and April, 1998, the Company sold 2,500,000 shares of its
         common stock through private offerings. Proceeds from the offerings
         totaled $14.5 million.

         In connection with certain 1998 acquisitions, the Company has entered
         into employment agreements with 8 employees. Upon termination of
         employment (other than voluntarily by the employee or by the Company
         for cause or upon death of the employee), the Company is committed to
         pay certain benefits, including specified monthly severance of not more
         than $6,667 per month.  The benefits are to be paid from the date of
         termination to dates ranging from January 22, 1999 to March 6, 2001.

         On April 30, 1998, certain employees of the Company exercised
         options to purchase 612,500 shares at a price of $.65 per share.

         On May 13, 1998, pursuant to a Plan of Reorganization in the United
         States Bankruptcy Court, Microlytics, Inc. ("Microlytics") completed a
         merger (the "Merger") with the Company. Under the terms of the Merger,
         each outstanding share of SanTi common stock was exchanged for one
         share of Microlytics common stock. Immediately prior to the Merger,
         Microlytics had 1,027,066 shares of common stock outstanding and
         warrants to purchase an additional 500,000 shares with an exercise
         price of $5.80, of which 250,000 were exercised immediately following
         the Merger. The Merger resulted in the receipt by SanTi shareholders of
         approximately 8,088,379 shares of common stock,


                                      F-21
<PAGE>   48


   
         representing approximately 86.2% of the Microlytics shares outstanding
         on the effective date of the Merger. As a result of the Merger, SanTi
         was merged into Microlytics and Microlytics' certificate of
         incorporation was amended as of the effective date of the Merger to
         change Microlytics' name to SanTi. The Merger was accounted for as a
         capital transaction accompanied by a recapitalization of SanTi. All
         costs incurred in connection with the Merger were expensed.
    

         On June 1, 1998, the Company entered into employment agreements with
         three executive officers which provide for minimum aggregate annual
         compensation of $575,000. The agreements expire either June 1, 2000 or
         June 1, 2003, and automatically renew for twelve month periods. Upon
         termination of employment related to the change in control of the
         Company, the Company is committed to immediately pay in full the
         minimum compensation for each of the remaining years or portion
         thereof.
   
         On June 26, 1998, the Company entered into a $40 million revolving
         credit facility with a bank. The Company may also obtain up to $5
         million in letters of credit, subject to availability under the
         facility. Interest is payable monthly at variable rates, depending on
         the Company's current debt to cash flow ratio, but is capped at LIBOR
         plus 2.5%. The facility expires June 26, 2001, is secured by a first
         lien on substantially all assets of the Company and requires the
         Company to maintain certain financial ratio covenants beginning
         September 30, 1998. The Company granted the bank a five-year warrant to
         purchase 50,000 shares of common stock at $13 per share in lieu of
         issuance costs. The warrant was valued at $100,000 using the Black-
         Scholes pricing model.
    
         On June 29, 1998, three executive officers received options to purchase
         an aggregate of 1,250,000 shares of common stock as follows; 400,000
         exercisable at $6 per share, 350,000 exercisable at $15 per share and
         500,000 exercisable at $25 per share.

                          NOTES TO FINANCIAL STATEMENTS

                               DECEMBER 31, 1996


1. ORGANIZATION AND BASIS OF PRESENTATION

   Andrews Environmental Services, Inc. ("Andrews" or the "Company"), a Georgia
   corporation, operates a service center that treats, processes, and recovers
   nonhazardous liquid waste to serve a variety of customers from private
   residences and municipalities to large industrial companies.

   On March 20, 1997, certain assets of the Company associated with its grease
   disposal business were sold to SanTi Group, Inc. ("SanTi"). The grease
   disposal business was primarily involved with commercial and governmental
   grease extraction, collection, and transportation services. Consideration
   associated with the sale was $475,000 in cash and $257,350 in notes
   receivable. In conjunction with the sale, the Company recorded a gain on the
   sale of fixed assets of $204,124 which is included in other income in the
   accompanying statement of operations for the period from January 1, 1997 to
   December 21, 1997.

   On December 22, 1997, substantially all of the remaining property and
   equipment and the ongoing business of the Company were sold to SanTi.
   Consideration was $660,000 in cash and 21,400 shares of SanTi common
   stock. Contingent consideration of 13,600 shares of SanTi common stock is
   receivable within 90 days of the first anniversary of the date of purchase,
   net of offsets for losses, as defined in the sale agreement.


2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   CASH AND CASH EQUIVALENTS

   The Company considers all highly liquid investments with maturities of three
   months or less at the date of purchase to be cash equivalents.

   CONCENTRATION OF CREDIT RISK

   Financial instruments which subject the Company to concentrations of credit
   risk consist principally of trade receivables. The Company's customers are
   concentrated in one geographic region. No single customer accounted for a
   significant amount of the Company's sales, and there are no significant
   accounts receivable from a single customer. The Company reviews a customer's
   credit history before extending credit. The Company establishes an allowance
   for doubtful accounts based on factors surrounding the credit risk of
   specific customers, historical trends, and other information.

   REVENUE RECOGNITION

   The Company recognizes revenues as services are provided.

   PROPERTY AND EQUIPMENT

   the estimated useful lives of the assets using the straight-line method. The
   estimated useful lives for machinery and equipment and office equipment range
   from 5 to 7 years. The building is depreciated over an estimated useful life
   of 40 years.

   At December 31, 1996, property and equipment consisted of the following:

</TABLE>

   
   The Company periodically reviews the values assigned to property and
   equipment to determine whether any impairments are other than temporary.
   The Company assesses impairment by determining whether the carrying value of
   such long-lived assets will be recovered through undiscounted expected future
   cash flows. No impairment losses have been recorded in the accompanying
   results of operations.
    
   
   USE OF ESTIMATES

   The preparation of financial statements in conformity with generally accepted
   accounting principles requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities and disclosure of
   contingent assets and liabilities at the date of the financial statements and
   the reported amounts of revenues and expenses during the reporting period.
   Actual results could differ from those estimates.

   UNAUDITED INTERIM FINANCIAL INFORMATION
   
   The accompanying financial statements for the six-month period ended June
   30, 1997 are unaudited. In the opinion of the management of Andrews, these
   financial statements reflect all adjustments, consisting only of normal
   recurring adjustments, necessary for a fair presentation of the financial
   statements.

   NEW ACCOUNTING PRONOUNCEMENTS

   In June 1997, the Financial Accounting Standards Board issued Statement of
   Financial Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive
   Income." SFAS No. 130 is designed to improve the reporting of changes in
   equity from period to period. The Company currently has no other
   comprehensive income items as defined by SFAS No. 130.

To Ferrero Wastewater Management, Inc.:


We have audited the accompanying balance sheets of FERRERO WASTEWATER

financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing

reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

                          NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 1996 AND 1997



1.   ORGANIZATION AND BASIS OF PRESENTATION

     Ferrero Wastewater Management, Inc. (the "Company") designs, constructs,
     repairs, maintains, and operates on-site sewage disposal systems, primarily
     in metropolitan Philadelphia, Pennsylvania.

     Nutrecon, Inc. disposed of the waste collected by the Company. On January
     1, 1997, the net assets of Nutrecon, Inc. were transferred to the Company.
     Since the companies were under common ownership from their respective dates
     of inception, the accompanying financial statements of the Company include
     the accounts of Nutrecon, Inc. for all periods presented. All material
     intercompany balances and transactions have been eliminated.


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid investments with maturities of
     three months or less at the date of purchase as cash equivalents.

     CONCENTRATION OF CREDIT RISK

     Financial instruments which subject the Company to concentrations of credit
     risk consist principally of trade receivables. The Company's customers are
     concentrated in one geographic region and in one line of business. No
     single customer accounted for a significant amount of the Company's sales,
     and there are no significant accounts receivable from a single customer.
     The Company reviews a customer's credit history before extending credit.
     The Company establishes an allowance for doubtful accounts based on factors
     surrounding the credit risk of specific customers, historical trends, and
     other information.

      REVENUE RECOGNITION

      The Company recognizes revenues as services are provided.

      PROPERTY AND EQUIPMENT

      Property and equipment are recorded at cost. Depreciation is provided over
      the estimated useful lives of the assets using the straight-line method.
      The estimated useful lives for

     machinery and equipment and office equipment range from five to seven 
     years. Buildings are depreciated over 20 years.

      At December 31, 1996 and 1997, property and equipment consisted of the
      following:

</TABLE>

   
      The Company periodically reviews the values assigned to property and
      equipment to determine whether any impairments are other than temporary.
      The Company assesses impairment by determining whether the carrying value
      of such long-lived assets will be recovered through undiscounted expected
      future cash flows. No impairment losses have been recorded in the
      accompanying results of operations.
    

      USE OF ESTIMATES

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      disclosure of contingent assets and liabilities at the date of the
      financial statements and the reported amounts of revenues and expenses
      during the reporting period. Actual results could differ from those
      estimates.

      UNAUDITED INTERIM FINANCIAL INFORMATION

   
      The accompanying financial statements for the six-month period ended
      June 30, 1997, and for the period from January 1, 1998 through January
      22, 1998 are unaudited. In the opinion of management, these financial
      statements reflect all adjustments, consisting only of normal recurring
      adjustments, necessary for a fair presentation of the financial
      statements. The results of operations for the period from January 1, 1998
      through January 22, 1998 are not necessarily indicative of future results
      of the Company.
    

      INCOME TAXES

      The Company has elected, for federal and state income tax purposes, S
      corporation tax status whereby income is taxed at the stockholder level.
      Therefore, no deferred tax assets, liabilities, or provision for income
      taxes is recorded.

   
      NEW ACCOUNTING PRONOUNCEMENTS

      In June 1997, the Financial Accounting Standards Board issued Statement
      of Financial Accounting Standards ("SFAS") No. 130, "Reporting
      Comprehensive Income." SFAS No. 130 is designed to improve the reporting
      of changes in equity from period to period. The Company currently has no
      other comprehensive income items as defined by SFAS No. 130.

                          NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 1996 AND 1997


1. ORGANIZATION AND BASIS OF PRESENTATION

   A Rapid Rooter Sewer & Drain Service, Inc. (the "Company") designs,
   constructs, repairs, maintains, and operates on-site sewage disposal systems,
   primarily in and around Pompano Beach, Florida.


2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   CASH AND CASH EQUIVALENTS

   The Company considers all highly liquid investments with maturities of three
   months or less at the date of purchase as cash equivalents.

   CONCENTRATION OF CREDIT RISK

   Financial instruments which subject the Company to concentrations of credit
   risk consist principally of trade receivables. The Company's customers are
   concentrated in one geographic region and in one line of business. No single
   customer accounted for a significant amount of the Company's sales, and there
   are no significant accounts receivable from a single customer. The Company
   reviews a customer's credit history before extending credit. The Company
   establishes an allowance for doubtful accounts based on factors surrounding
   the credit risk of specific customers, historical trends, and other
   information.

   REVENUE RECOGNITION

   The Company recognizes revenues as services are provided.

   PROPERTY AND EQUIPMENT

   Property and equipment are recorded at cost. Depreciation is provided over
   the estimated useful lives of the assets using the straight-line method. The
   estimated useful lives for machinery and equipment and office equipment range
   from five to seven years. Leasehold improvements are depreciated over the
   shorter of the term of the lease or the useful life of the improvements.

</TABLE>

   
   The Company periodically reviews the values assigned to property and
   equipment to determine whether any impairments are other than temporary.
   The Company assesses impairment by determining whether the carrying value of
   such long-lived assets will be recovered through undiscounted expected
   future cash flows. No impairment losses have been recorded in the
   accompanying results of operations.   
    

   USE OF ESTIMATES

   The preparation of financial statements in conformity with generally accepted
   accounting principles requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities and disclosure of
   contingent assets and liabilities at the date of the financial statements and
   the reported amounts of revenues and expenses during the reporting period.
   Actual results could differ from those estimates.

   UNAUDITED INTERIM FINANCIAL INFORMATION
   
   The accompanying financial statements as of February 13, 1998, for the
   six-month period ended June 30, 1997, and for the period from January 1,
   1998 through February 13, 1998 are unaudited. In the opinion of management,
   these financial statements reflect all adjustments, consisting only of normal
   recurring adjustments, necessary for a fair presentation of the financial
   statements. The results of operations for the period from January 1, 1998
   through February 13, 1998 are not necessarily indicative of future results of
   the Company.
    

   INCOME TAXES

   For federal and state income tax purposes, the Company has elected S
   corporation tax status whereby income is taxed at the stockholder level.
   Therefore, no deferred tax assets, liabilities, or provision for income taxes
   is recorded. Amounts are distributed to stockholders for making applicable
   tax payments, and are included in distributions to stockholders in the

We have audited the accompanying combined balance sheets of SEAGRAVES, INC. (a
Florida corporation d.b.a. Brownie Environmental Services) AND GREASE-TEC, INC.
(a Florida corporation) as of December 31, 1997 and 1996 and the related
combined statements of operations, stockholders' equity, and cash flows for each
of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Seagraves, Inc. (d.b.a.
Brownie Environmental Services) and Grease-Tec, Inc. as of December 31, 1997

  2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      PRINCIPLES OF COMBINATION

      The accompanying combined financial statements include the accounts of
      Seagraves, Inc. and Grease-Tec, Inc. All significant intercompany accounts
      have been eliminated.

      CASH AND CASH EQUIVALENTS

      The Company considers all highly liquid investments with maturities of
      three months or less at the date of purchase to be cash equivalents.

      CONCENTRATION OF CREDIT RISK

      Financial instruments which subject the Company to concentrations of
      credit risk consist principally of trade receivables. The Company's
      customers are concentrated in one geographic region. No single customer
      accounted for a significant amount of the Company's sales, and there are
      no significant accounts receivable from a single customer. The Company
      reviews a customer's credit history before extending credit. The Company
      establishes an allowance for doubtful accounts based on factors
      surrounding the credit risk of specific customers, historical trends, and
      other information.

      REVENUE RECOGNITION

      The Company recognizes revenues as services are provided.

      PROPERTY AND EQUIPMENT

      Property and equipment are recorded at cost. Depreciation is provided on
      the straight-line basis using useful lives of 5 to 7 years for machinery
      and equipment and office equipment and 20 years for building and
      improvements.

      At December 31, 1996 and 1997, property and equipment consisted of the
      following:

</TABLE>

   
      The Company periodically reviews the values assigned to property and
      equipment to determine whether any impairments are other than temporary.
      The Company assesses impairment by determining whether the carrying value
      of such long-lived assets will be recovered through undiscounted expected
      future cash flows. No impairment losses have been recorded in the
      accompanying results of operations.
    

      USE OF ESTIMATES

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      disclosure of contingent assets and liabilities at the date of the
      financial statements and the reported amounts of revenues and expenses
      during the reporting period. Actual results could differ from those
      estimates.

      UNAUDITED INTERIM FINANCIAL INFORMATION

   
      The accompanying financial statements for the six-month period ended
      June 30, 1997 and for the period from January 1, 1998 through March 6,
      1998 are unaudited. In the opinion of management, these financial
      statements reflect all adjustments, consisting only of normal and
      recurring adjustments, necessary for a fair presentation of the financial
      statements. The results of operations for the period from January 1, 1998
      through March 6, 1998 are not necessarily indicative of future results of
      the Company.
    

      INCOME TAXES

      The Company has elected for federal and state income tax purposes S
      corporation tax status, whereby income is taxed at the stockholder level.
      Therefore, no deferred tax assets, liabilities, or provisions for income
      taxes are recorded. Amounts are distributed to the stockholders for making
      applicable tax payments.

   
      NEW ACCOUNTING PRONOUNCEMENTS

      In June 1997, the Financial Accounting Standards Board issued Statement
      of Financial Accounting Standards ("SFAS") No. 130, "Reporting
      Comprehensive Income." SFAS No. 130 is designed to improve the reporting
      of changes in equity from period to period. The Company currently has no
      other comprehensive income items as defined by SFAS No. 130.

                      RGM LIQUID WASTE REMOVAL CORPORATION

                                 AND AFFILIATES


                     NOTES TO COMBINED FINANCIAL STATEMENTS

                            OCTOBER 31, 1996 AND 1997


   
  1.  ORGANIZATION AND BASIS OF PRESENTATION

      RGM Liquid Waste Removal Corporation ("RGM") and affiliates (collectively,
      the "Company") is engaged in the removal of various waste materials. As
      part of its normal operations, the Company enters into agreements of up to
      four years with governmental, institutional, and commercial entities.
      These agreements specify that the Company will remove various waste
      materials at per unit prices. Billings are submitted as services are
      provided.
    

  2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      PRINCIPLES OF COMBINATION

      The accompanying combined financial statements include the accounts of
      Devito Environmental Corporation ("Devito"), Advanced Transfer Technology,
      Inc. ("ATT"), and Envirotech Leasing & Rental Corporation ("Envirotech")
      (collectively, the "Affiliates") since they have been under the same
      ownership of RGM since their respective dates of inception. All material
      intercompany accounts have been eliminated.

      CASH AND CASH EQUIVALENTS

      The Company considers all highly liquid investments with maturities of
      three months or less at the date of purchase to be cash equivalents.

      The carrying amounts of short-term investments approximate fair value.
      Short-term investments consist of marketable equity securities and money
      market funds. In accordance with the criteria specified by Statement of
      Financial Accounting Standards ("SFAS") No. 115, "Accounting for Certain
      Investments in Debt and Equity Securities," these investments were
      classified as available for sale.

      CONCENTRATION OF CREDIT RISK

      Financial instruments which subject the Company to concentrations of
      credit risk consist principally of trade receivables. The Company's
      customers are concentrated in one geographic region. No single customer
      accounted for a significant amount of the Company's sales, and there are
      no significant accounts receivable from a single customer. The Company
      reviews a customer's credit history before extending credit. The Company

                                      F-64
<PAGE>   91


      establishes an allowance for doubtful accounts based on factors
      surrounding the credit risk of specific customers, historical trends, and
      other information.

      REVENUE RECOGNITION

      The Company recognizes revenues as services are provided.

      PROPERTY AND EQUIPMENT

      Property and equipment are recorded at cost. Depreciation is provided
      using useful lives of five to ten years for machinery and equipment and
      office equipment. Leasehold improvements are depreciated over the shorter
      of the term of the lease or the useful life of the improvements.

      At October 31, 1996 and 1997, property and equipment consisted of the
      following:

</TABLE>
   
      The Company periodically reviews the values assigned to property and
      equipment to determine whether any impairments are other than temporary.
      The Company assesses impairment by determining whether the carrying value
      of such long-lived assets will be recovered through undiscounted expected
      future cash flows. No impairment losses have been recorded in the
      accompanying results of operations.
    
      COMMON STOCK

      No par value common stock of RGM and affiliates consists of the following
      as of October 31, 1996 and 1997 and January 31, 1998:

</TABLE>

      USE OF ESTIMATES

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      disclosure of contingent assets and liabilities 

                                      F-65
<PAGE>   92



      at the date of the financial statements and the reported amounts of
      revenues and expenses during the reporting period. Actual results could
      differ from those estimates.

      UNAUDITED INTERIM FINANCIAL INFORMATION

   
      The accompanying financial statements as of April 30, 1998 and for the
      six-month periods ended April 30, 1997 and 1998 are unaudited. In the
      opinion of management, these financial statements reflect all adjustments,
      consisting only of normal recurring adjustments, necessary for a fair
      presentation of the financial statements. The results of operations for
      the six-month period ended April 30, 1998 are not necessarily indicative
      of future results of the Company.
    

      INCOME TAXES

      For federal and state income tax purposes, two of the affiliates (the "S
      corporations") have elected S corporation tax status whereby income is
      taxed at the shareholder level. Therefore, no deferred tax assets,
      liabilities, or provisions for income taxes is recorded. See Note 7 for
      income tax information for the two affiliates which are C corporations
      (the "C corporations").

   
      NEW ACCOUNTING PRONOUNCEMENTS

      In June 1997, the Financial Accounting Standards Board issued Statement of
      Financial Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive
      Income." SFAS No. 130 is designed to improve the reporting of changes in
      equity from period to period. The Company currently has no other
      comprehensive income items as defined by SFAS No. 130.
    

  3.  NOTE RECEIVABLE

   
      From July 1992 to June 1996, the Company participated in the Merco Joint
      Venture ("Merco"), which was accounted for using the equity method of
      accounting. Merco contracts with the city of New York to receive,
      transport, and dispose of dewatered sewage sludge. The Company's ownership
      interest in Merco was 33 1/3%. At May 31, 1996, the Company's investment
      in Merco was $2,439,761. On June 1, 1996, pursuant to a settlement

      future cash flows. No impairment losses have been recorded in the 
      accompanying results of operations.

      USE OF ESTIMATES

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      disclosure of contingent assets and liabilities as of the date of the
      financial statements and the reported amounts of revenues and expenses
      during the reporting period. Actual results could differ from those
      estimates.

      UNAUDITED INTERIM FINANCIAL INFORMATION

   
      The accompanying financial statements for the six-month period ended June
      30, 1997 and for the period from January 1, 1998 to May 8, 1998 are
      unaudited. In the opinion of the management of the Company, these
      financial statements reflect all adjustments, consisting only of normal
      recurring adjustments, necessary for a fair presentation of the financial
      statements. The results of operations for the period from January 1, 1998
      to May 8, 1998, are not necessarily indicative of the future results of
      the Company.

      NEW ACCOUNTING PRONOUNCEMENTS

      In June 1997, the Financial Accounting Standards Board issued Statement
      of Financial Accounting Standards ("SFAS") No. 130, "Reporting
      Comprehensive Income." SFAS No. 130 is designed to improve the reporting
      of changes in equity from period to period. The Company currently has no
      other comprehensive income items as defined by SFAS No. 130.
