                     INTERNATIONAL ALLIANCE SERVICES, INC.
 
                                  COMMON STOCK
 
                             ---------------------
     This Prospectus relates to 32,126,076 shares (the "Shares") of common
stock, par value $.01 per share ("Common Stock"), of International Alliance
Services, Inc., a Delaware corporation (formerly known as Republic Environmental
Systems, Inc., the "Company"), of which up to 17,925,888 are issuable upon
exercise of outstanding warrants. Shares may be offered from time to time (the
"Offering") by persons (the "Selling Stockholders") who have acquired such
Shares in certain private placements and other transactions not involving a
public offering. The Shares are being registered under the Securities Act of
1933, as amended (the "Securities Act"), on behalf of the Selling Stockholders
in order to permit the public or private sale or other public or private
distribution of the Shares.
 
     The Shares may be sold or distributed from time to time by or for the
account of the Selling Stockholders, or by their pledgees on behalf of the
Selling Stockholders, in transactions (which may involve crosses and block
transactions) on the Nasdaq National Market ("Nasdaq") or any national
securities exchange or U.S. inter-dealer quotation system of a registered
national securities association on which the Shares are then listed, in the
over-the-counter market, in one or more privately negotiated transactions
(including sales pursuant to pledges), through the writing of options on the
Shares, in a combination of such methods of distribution or by any other legally
available means; including the distribution by Alliance Holding Corporation, an
Ohio corporation and Selling Stockholder ("Alliance"), to its stockholders and
debt holders of the Shares which are not sold or otherwise transferred by
Alliance. This Prospectus also may be used, with the Company's consent, by
donees of the Selling Stockholders, or by other persons acquiring Shares and who
wish to offer and sell such Shares under circumstances requiring or making
desirable its use. Such methods of sale may be conducted by the Selling
Stockholders at market prices prevailing at the time of sale, at prices related
to such prevailing market prices or at prices otherwise negotiated. The Selling
Stockholders may effect such transactions directly, or indirectly through
broker-dealers or agents acting on their behalf and, in connection with such
sales, such broker-dealers or agents may receive compensation in the form of
commissions or discounts from the Selling Stockholders and/or the purchasers of
the Shares for whom they may act as agent or to whom they sell Shares as
principal or both (which commissions or discounts might be in excess of
customary commissions). To the extent required, the names of donees of Selling
Stockholders and names of the agents or broker-dealers, and applicable
commissions or discounts and any other required information with respect to any
particular offer of Shares by the Selling Stockholders, will be set forth in a
Prospectus Supplement. See "Plan of Distribution."
 
     The Company will not receive any of the proceeds from the sale of the
Shares offered hereby, but will bear all expenses incident to the registration
of the Shares under federal and state securities laws and the sale of the Shares
hereunder other than expenses incident to the delivery of the Shares to be sold
by the Selling Stockholders, including any transfer taxes payable on any Shares,
and any commissions and discounts payable to underwriters, agents or dealers.
 
     The Common Stock is quoted on Nasdaq under the symbol "IASI." On January

                                  RISK FACTORS
 
     IN ADDITION TO THE OTHER INFORMATION SET FORTH IN THIS PROSPECTUS,
PROSPECTIVE PURCHASERS OF THE SHARES SHOULD CONSIDER CAREFULLY THE FOLLOWING
RISK FACTORS IN EVALUATING AN INVESTMENT IN THE COMPANY.
 
RISKS RELATED TO THE COMPANY
 
  Strategy for Future Acquisitions; Limited Operating History; Need for
  Substantial Additional Capital
 
     The Company's current business strategy is to act aggressively in making
acquisitions in the specialty insurance industry and the business consulting and
management services industry. The Company acquired the Insurance Subsidiaries
(defined herein) in October 1996, Environmental & Commercial Insurance Agency,
Inc. ("ECI") in November 1996 and SMR & Co. Business Services (formerly known as
SMR & Co., "SMR") in December 1996. On an aggregate basis, revenue for these
newly acquired businesses totaled over $38.0 million for the year ended December
31, 1995, compared with the Company's $44.0 million in revenue for the same
period. Accordingly, the Company has no operating history with regard to a
significant portion of its current operations. The financial position and
results of operations of the Company will depend to a large extent on the
Company's ability to integrate these and subsequently acquired operations
effectively. As the Company continues to pursue its acquisition strategy in the
future, its financial position and results of operations may fluctuate
significantly from period to period.
 
     On December 30, 1996, the Company received approximately $27.6 million in
net proceeds from the offering (the "Private Placement") of 3,251,888 units of
the Company (the "Units"), after deducting the placement agent fee and other
estimated expenses associated with the Private Placement. Each Unit consisted of
one share of Common Stock of the Company and one warrant to purchase one share
of Common Stock of the Company at an exercise price of $11.00 per share. In
addition, MGD Holdings and Messrs. Harve A. Ferrill and Richard C. Rochon,
directors of the Company, have entered into agreements to purchase an aggregate
of 616,611 Units. On January 6, 1997, the issuance of such Units was approved by
written consent of the holders of a majority of the outstanding shares of Common
Stock. Upon the closing of the issuance of the Units to MGD Holdings and Messrs.
Ferrill and Rochon, the Company will receive an additional $5.3 million in
proceeds from the Private Placement. See "Recent Developments -- Private
Placement Transaction." The Company will use the proceeds received from the
Private Placement, in part, to finance acquisitions. Future acquisitions,
however, may require additional equity and debt financing, although neither form
of financing is contemplated at this time. In the event the Company is required
to seek additional financing, there is no assurance that such additional
financing will be available or, if it is available, that it will be available on
terms acceptable to the Company.
 
  Risks Related to Growth Through Acquisitions; Failure to Manage Growth
 
     The Company intends to continue its internal growth and to pursue an
aggressive acquisition strategy. Internal growth may place a significant strain
on the Company's management, operating and technical resources, while growth
through acquisitions will involve substantial risks, including the risk of
improper valuation of the acquired businesses and the risks inherent in
integrating such businesses with the Company's operations. The Company's
acquisition strategy depends on its ability to identify and acquire appropriate
specialty insurance companies and business services companies, to integrate the
acquired operations effectively, and to increase its market share. A number of
the Company's competitors for such acquisitions are larger, better known
companies than the Company with significantly greater financial resources. There
can be no assurance that the Company will be able to locate acquisition
candidates in geographic markets or on terms the Company deems attractive, that
any identified candidates will be acquired, that the Company will be able to
profitably manage acquired companies, or that future acquisitions will produce
financial returns that justify the investment or that are comparable to the
Company's past returns. The completion of acquisitions requires the expenditure
of sizable amounts of capital, as well as management's time and attention, and
the intense competition among companies pursuing similar acquisition strategies
may increase capital requirements. There can be no assurance that management
skills and systems currently in place will be adequate to implement the
Company's acquisition strategy. The failure to manage growth effectively, or to
implement its
 
                                        4
   5
 
acquisition strategy, could have a material adverse effect on the Company's
results of operations and financial condition.
 
  Risks Associated with Acquisitions
 
     Although the Company investigates each business that it acquires, there may
be liabilities that the Company fails or is unable to discover. The Company
seeks to minimize the impact of any such liabilities by obtaining indemnities
and warranties from the seller of the business which may be supported by
deferring payment of a portion of the purchase price. However, these indemnities
and warranties, if obtained, may not fully cover the liabilities due to the
limited scope, amount or duration of the indemnities, the financial limitations
of the indemnitor or warrantor, or other reasons.
 
  Control by Alliance
 
     As a result of the Merger Transactions (defined herein), on January 21,
1997, Alliance beneficially owned 26,156,000 shares, or 68.2% of the outstanding
shares of the Company's Common Stock (the "Alliance Shares"). The Alliance
Shares include 7,196,000 shares (the "MGD Shares") of the Company's Common Stock
owned of record by MGD Holdings on January 21, 1997 and warrants to purchase
4,200,000 shares of Common Stock owned by Alliance. Alliance shares voting power
with respect to the MGD Shares under a voting agreement, dated October 18, 1996
(the "Voting Agreement"), between Alliance and MGD Holdings. Pursuant to the
Voting Agreement, MGD Holdings, for a period of two years from the date thereof,
agreed to vote all shares of Common Stock held by MGD Holdings from time to time
in accordance with the recommendations of the management of Alliance.
Accordingly, Alliance has the capability to determine the outcome of any vote of
the Company's stockholders during this period. Further, four of the seven
members of the Board of Directors were nominated by Alliance. As a result,
Alliance has effective control of the Company's Board of Directors. Alliance has
reached an agreement with one of its institutional lenders to exchange 1,370,000
shares of Common Stock and warrants to purchase 85,000 shares of Common Stock
currently held by Alliance for the cancellation of existing indebtedness of
Alliance. Fifty percent of such shares and all of such warrants will remain
subject to a lock-up agreement between Alliance and the Company (as more fully
described in the Company's definitive Schedule 14C Information Statement dated
September 23, 1996) until October 17, 1998. The remaining 685,000 shares of
Common Stock will not be subject to the lock-up after April 17, 1997.
 
  Dependence on Key Personnel
 
     The Company depends and will continue to depend in the foreseeable future
on the services of Messrs. Michael G. DeGroote, Edward F. Feighan, Craig L.
Stout, Joseph E. LoConti, Douglas R. Gowland and certain of its other officers
and key employees with extensive experience and expertise in the insurance
specialty industry and the waste and environmental services industry. In
addition, with respect to its provision of business services, the Company is
dependent on the services of Messrs. Gregory J. Skoda, Michael L. Minotti, Keith
W. Reeves, Patrick T. Carney, Terry L. Silver and certain of its other key
personnel with extensive experience and expertise in such industry. The ability
of the Company to retain its officers and key employees is important to the
success of the Company. The loss of key personnel, whether by resignation or
otherwise, including the election of directors, could have a material adverse
effect on the Company. The Company does not maintain key personnel insurance on
any of its officers or employees.
 
  Possible Depressing Effect of Future Sales of Common Stock
 
     No predictions can be made as to the effect, if any, that future sales of
the Shares, the availability of Common Stock for sale or the perception that
such sales could occur will have on the prevailing market price of the Common
Stock. On November 6, 1996, the Company completed the acquisition of ECI in
exchange for 192,500 shares of Common Stock (the "ECI Shares") and $1.0 million
in cash and, on December 1, 1996, the Company completed the acquisition of SMR
in exchange for 600,000 shares of Common Stock and warrants to purchase an
additional 900,000 shares of Common Stock. On January 7, 1997, the Company
completed the acquisition of certain of the assets and business of Midwest
Indemnity Corporation ("Midwest") in exchange
 
                                        5
   6
 
for approximately $3.3 million in cash, 407,246 shares of the Company's Common
Stock and approximately $1.8 million in non-interest bearing notes payable in
installments through December 31, 1998. See "Recent Developments." It is the
Company's intent to register under the Securities Act, during the first quarter
of 1997, the shares issued and issuable in these recent acquisitions for resale
by the holders thereof.
 
     In addition to the acquisitions described above, the Company has issued
Common Stock and options or warrants to purchase Common Stock pursuant to
exemptions from registration available under the Securities Act in connection
with certain of its prior acquisitions, and intends to issue Common Stock and
options and warrants to purchase shares of Common Stock in connection with
future acquisitions. Although such securities are or will be, as the case may
be, subject to restrictions on resale in accordance with the Securities Act and
the regulations promulgated thereunder, as such restrictions lapse or if such
shares are registered for sale to the public, such securities may be sold into
the public market. In the event of the issuance and subsequent resale of a
substantial number of shares of Common Stock, or a perception that such sales
could occur, there could be a material adverse effect on the prevailing market
price of the Common Stock.
 
  Dilution
 
     The issuance of additional shares of Common Stock upon exercise of
outstanding warrants or options, or upon the Company's completion of any
acquisitions and business combinations, may have a dilutive effect on earnings
per share and will have a dilutive effect on the voting rights of the holders of
Common Stock. On December 26, 1996, the Board approved the issuance of warrants
to purchase 1,000,000 shares of Common Stock at an exercise price of $11.00 per
share to MGD Holdings in consideration for services rendered, subject to
stockholder approval. In addition, as part of the Private Placement, the Company
entered into agreements with MGD Holdings and Messrs. Ferrill and Rochon to
issue an additional 616,611 Units in the Private Placement, subject to
stockholder approval. Such Units consist of an aggregate of 616,611 shares of
Common Stock and warrants to purchase an aggregate of 616,611 shares of Common
Stock at an exercise price of $11.00 per share. See "Recent
Developments -- Private Placement Transaction."
 
  No Cash Dividends
 
     The payment and level of dividends on Common Stock are subject to the
discretion of the Board of Directors of the Company. The payment of dividends
will depend upon business decisions that will be made by the Board of Directors
of the Company from time to time based upon the results of operations and
financial conditions of the Company and its subsidiaries and such other
considerations as the Board of Directors considers relevant. In addition, the
Company's credit facility currently prohibits payment of dividends and other
distributions to the stockholders of the Company. Since the Spin-off (defined
herein) in April 1995, the Company has not paid cash dividends on its Common
Stock and the Company's Board of Directors does not anticipate paying cash
dividends in the foreseeable future. The Company currently intends to retain
future earnings to finance the ongoing operations and growth of the business.
 
RISKS RELATED TO THE PROVISION OF WASTE SERVICES
 
  Consents of Regulatory Authorities
 
     On October 18, 1996, the Company consummated the merger of Century Surety
Company, an Ohio corporation ("CSC" and, together with its subsidiaries, the
"CSC Group"), and Commercial Surety Agency, Inc., d/b/a Century Surety
Underwriters, an Ohio corporation ("CSU" and, together with CSC and its
subsidiaries, the "Insurance Subsidiaries"), into wholly-owned subsidiaries of
the Company (the "Merger Transactions"). As a result of the Merger Transactions,
the Company and the Insurance Subsidiaries were required to seek consents from
certain regulatory authorities. The Ohio attorney general's office determined
that the Merger Transactions constitute a change of ownership of Ohio
Environmental Protection Agency ("Ohio EPA") permitted facilities owned by
Republic Environmental Systems (Cleveland) Inc. ("RES (Cleveland)") and Republic
Environmental Systems (Ohio), Inc. ("RES (Ohio)"). In addition, the Ohio EPA may
determine that the Merger Transactions constitute a modification of such
permits. As a result, Ohio law requires that the change of ownership of the
permitted facilities, as well as the permit modifications, if any, be approved
by the director of the Ohio EPA, based upon the disclosure statements and an
investigative report
 
                                        6
   7
 
prepared by the Ohio attorney general's office. The Company consummated the
Merger Transactions prior to receipt of the requisite approval of the director
of the Ohio EPA as permitted by applicable law. During the approval process, the
Company does not anticipate that the operations at such facilities will be
affected. In the event that the director of the Ohio EPA ultimately disapproves
such change of ownership or, if required, such permit modifications, the Company
would be required to effect the negation of the change of ownership of such
facilities. The negation could be accomplished through the restoration of the
original ownership structure of such facilities, the disposition of the
facilities or another means that complies with the requirements of applicable
law. The failure to obtain approval of such change of ownership or permit
modifications, if any, could have a material adverse effect on the financial
condition and operations of the Company.
 
  Regulation
 
     The collection and disposal of solid and chemical wastes and rendering of
related environmental services are subject to federal, state, provincial and
local requirements which regulate health, safety, the environment, zoning and
land-use. Operating permits are generally required for treatment, storage and
disposal facilities ("TSD Facilities") and certain collection vehicles, and
these permits are subject to revocation, modification and renewal. Federal,
state, provincial and local regulations vary, but generally govern disposal
activities and the location and use of facilities and also impose restrictions
to prohibit or minimize air and water pollution. In addition, governmental
authorities have the power to enforce compliance with these regulations and to
obtain injunctions or impose fines in the case of violations, including criminal
penalties. These regulations are administered by the U.S. Environmental
Protection Agency (the "EPA") and various other federal, state, provincial and
local environmental and health and safety agencies and authorities, including
the Occupational Safety and Health Administration of the U.S. Department of
Labor. In addition, certain of the Company's operations are regulated under
applicable laws and regulations in Canada.
 
     The Company believes that in the existing climate of heightened legal,
political and citizen awareness and concerns, companies in the waste management
and environmental services industry, including the Company, may be faced with
material fines and penalties and the need to expend funds for remedial work and
related activities at TSD Facilities. The Company has established a reserve
(which as of December 31, 1996 was approximately $3.2 million) to cover such
fines, penalties and costs which the Company's management believes will be
adequate. Further, in connection with Republic Industries, Inc.'s (formerly
known as Republic Waste Industries, Inc., "RII") acquisition of the Company,
certain former stockholders of the Company agreed to indemnify the Company
against certain environmental liabilities. There can be no assurance, however,
that such reserve or indemnities will be adequate or that technological,
regulatory or enforcement developments, the results of environmental studies or
other factors will not have a material adverse effect on the Company's business
and consolidated financial condition.
 
     The Company's operation of TSD Facilities subjects it to certain operating,
monitoring, site maintenance, closure and post-closure obligations, including
posting significant financial assurance requirements for such obligations. In
order to construct, expand and operate a TSD Facility, one or more construction
or operating permits, as well as zoning approvals, must be obtained. These
construction and operating permits and zoning approvals are difficult and
time-consuming to obtain, and the issuance of such permits and approvals often
is opposed by neighboring landowners and local and national citizens' groups.
Once obtained, the operating permits may be subject to periodic renewal and are
subject to modification and revocation by the issuing agencies. In connection
with the Company's acquisition of TSD Facilities, it often may be necessary to
expend considerable time, effort and money to bring the acquired facilities into
compliance with applicable requirements and to obtain the permits and approvals
necessary to increase their capacity.
 
     Governmental authorities have the power to enforce compliance with
regulations and permit conditions and to obtain injunctions or impose fines in
case of violations. Citizens' groups may also bring suit for alleged violations.
During the ordinary course of its operations, the Company has from time to time
received citations or notices from such authorities that its operations are not
in compliance with applicable environmental or health or safety regulations.
Upon receipt of such citations or notices, the Company works with the
authorities to attempt to resolve the issues raised. Failure to correct the
problems to the satisfaction of the authorities
 
                                        7
   8
 
could lead to monetary or criminal penalties, curtailed operations or facility
closures which could have a material adverse effect on the Company's business
and consolidated financial condition.
 
     Subtitle D of the Resource Conservation and Recovery Act of 1976, as
amended ("RCRA"), establishes a framework for regulating the disposal of
non-hazardous solid wastes. In the past, the Subtitle D framework has left the
regulation of non-hazardous waste disposal largely to the states. On October 9,
1991, however, the EPA promulgated a final rule which imposes minimum federal
comprehensive solid waste management criteria and guidelines including location
restrictions, facility design and operating criteria, closure and post-closure
requirements, financial assurance standards, groundwater monitoring requirements
and corrective action standards. Because some parts of the new regulations will
be phased in over time, the full effect of these regulations may not be felt for
several years. However, other than for groundwater monitoring and financial
assurance requirements, all provisions of the final rule became effective
October 9, 1993. Operating and design criteria for existing operations may have
to be modified to comply with these new regulations. In addition, new
requirements applicable to the disposal of non-hazardous solid waste may be
adopted when reauthorization of RCRA is taken up by Congress and the Company
cannot predict the effect of such new requirements.
 
  Possibility of Liability for Hazardous Substance Remediation and Damages
 
     With very limited exceptions, federal law imposes joint and several
liability upon present and former owners and operators of facilities that
release "hazardous substances" into the environment and the generators and
transporters of those substances, regardless of the care exercised by such
persons and regardless of when the hazardous substance is first detected in the
environment. All such persons may be liable for the costs of waste site
investigation, waste site cleanup and damages to natural resources. There is an
inherent industry risk of liability arising from the release of "hazardous
substances" into the environment, notwithstanding safety and other measures
taken by the Company and other owners or operators of facilities. In addition,
because the term "hazardous substance" is very broadly defined under applicable
federal law, "hazardous substances" or "hazardous wastes" may have been
deposited in properties with which the Company has been, or will become,
associated as an owner or operator. Moreover, waste collection companies
acquired by the Company have transported hazardous waste in the past and will do
so in the future, and some of the Company's operations may generate small
amounts of hazardous waste. As a result of the foregoing, the Company may face
claims for remediation of environmental contamination, personal injury or damage
to natural resources at sites with which it is, or has been, associated as
owner, operator, transporter or waste generator and from which there is a
release or threatened release of hazardous substances which causes the
incurrence of response costs and damages. Costs for remediation of, and damages
for, environmental contamination can be very substantial. Given the limitations
in insurance coverage for these risks, such liability could have a material
adverse effect on the Company's business and consolidated financial condition.
 
  Legal Proceedings
 
     The Company is a party to various legal and environmental proceedings which
have arisen in the ordinary course of its business. No assurance can be given
with respect to the outcome of these legal proceedings and the effect such
outcomes may have on the Company.
 
  Lack of Environmental Liability Insurance
 
     The majority of the Company's domestic locations currently carry
site-specific pollution legal liability insurance, which may provide coverage
under certain circumstances for pollution damage to third parties. In addition,
the Company's domestic contracting operations carry contractors' pollution
liability insurance, which may provide coverage under certain circumstances for
damage to third parties. However, both of these coverages are restrictive in
nature, as they are subject to certain exclusions and effective dates,
consistent with insurance industry requirements. In addition, such coverage is
subject to specific and aggregate limits which may not be sufficient to cover
claims, if they should arise.
 
     In prior years, consistent with industry trends, the Company was not able
to obtain pollution insurance at reasonable costs and, therefore, carried only
such coverage as was required by regulatory permits. In addition,
 
                                        8
   9
 
the extent of insurance coverage under certain forms of policies has been the
subject in recent years of litigation in which insurance companies have, in some
cases, successfully taken the position that certain risks are not covered by
such policies. If, in the absence of such insurance, the Company were to incur
liability for environmental damages of sufficient magnitude, it could have a
material adverse effect on the Company's business and consolidated financial
condition.
 
  Competition
 
     The hazardous waste industry is highly competitive. Entry and ongoing
operations require substantial technical, managerial and financial resources.
The Company competes with large national companies and with regional and local
companies, some of which have significantly greater financial resources and more
established market positions than the Company.
 
RISKS RELATED TO THE PROVISION OF INSURANCE AND BONDING SERVICES
 
  Inadequate Pricing Risk
 
     The primary risk of any insurance enterprise is the risk of inadequate
pricing, which is a problem that manifests itself in the form of an unexpectedly
high level of claims after policy issuance. The Company utilizes a variety of
actuarial and qualitative methods to set price levels. Ultimately, however,
pricing depends upon an evaluation of prior experience as a predictor of future
experience. Events or trends that have not occurred in the past may not be
anticipated for the future and, therefore, could result in inadequate pricing
leading to elevated levels of losses. Such losses, if they were to occur, could
have a material adverse effect on the financial condition of the Company.
 
  Unanticipated Losses Due to Inadequate Reserve Estimates
 
     When claims are made, the ultimate amount of liability cannot be determined
until claims are paid to the satisfaction of the insured or until litigation
finally determines liability in disputed cases. Since the process of litigation
and settlement can continue for years, the Company can only assess its ultimate
liability (and the ultimate expense of litigating disputed issues) by
estimation. These estimates, or reserves for losses and loss adjustment expense
(which, as of September 30, 1996, were $40.5 million) are, like prices,
determined by a variety of actuarial and qualitative methods based on prior
experience. There can be no assurance that such reserves will be sufficient to
cover the ultimate liabilities of the Company for policy and bond exposures.
 
     The Company uses a reserving system which it believes will enable it to
meet claims obligations. Due to the nature of some of the coverages written,
claims may be presented which may not be settled for many years after they are
incurred; thus, subjective judgments as to the ultimate exposure to losses are
an integral and necessary component of the loss reserving process. The Company
regularly reviews reserves, using a variety of statistical and actuarial
techniques to analyze current claim costs, frequency and severity data, and
prevailing economic, social and legal factors. Reserves established in prior
years are adjusted as dictated by changes in loss experience and as new
information becomes available. An integral part of the reserving policy of the
Company includes a reserve for incurred but not reported ("IBNR") claims. There
can be no assurance that the assumptions upon which reserves are based are valid
or will be valid in the future.
 
     To help assure the adequacy of its IBNR reserves and individual case
reserves, the Company submits to an annual review by professional actuaries who
test reserve adequacy with a variety of sophisticated mathematical models. In
recent years, such actuaries have certified that reserve levels of the Company
are adequate. There can be no assurance, however, that the modeling techniques
of these actuaries will correctly forecast the adequacy of the Company's
reserves.
 
     The inadequacy of reserves may result in unanticipated losses which could
have a material adverse effect on the financial condition of the Company.
 
                                        9
   10
 
  Competition
 
     Both the property and casualty and the surety industries have been highly
competitive in recent years resulting in the consolidation of some of the
industries' largest companies. Competition is particularly acute for smaller,
specialty carriers like the Company because the market niches exploited by the
Company are small and can be penetrated by a larger carrier that elects to cut
prices or expand coverage. The Company's insurance subsidiaries have endured
this risk historically by maintaining a high level of development of new
products, such as its environmental coverage and landfill bonds eschewed by most
major carriers. Nevertheless, there can be no assurance that future development
efforts will succeed or that product erosion from intensifying competition will
not outpace development efforts.
 
  Expansion of Insurance Liability Due to Law Changes
 
     The Company is vulnerable to both judicial and legislative law changes with
respect to its insurance and bonding business. Judicial expansion of terms of
coverage can increase risk coverage beyond levels contemplated in the
underwriting and pricing process. Judicial imposition of pollution liability on
insurers before the era of specific pollution exclusions in insurance policies
created an estimated $25 billion liability, according to industry estimates
reported by A.M. Best, a leading rating agency of insurance companies and
reinsurers, for U.S. insurers and reinsurers that such companies did not know
they were underwriting and for which they received no premium.
 
  Change in Governmental Regulation
 
     Coverages that are established by statute may be adversely affected by
legislative or administrative changes of law. Most surety bonds exist because
they are required by government agencies. When governments change the threshold
for requiring surety, the market for surety bonds is directly affected. Indeed,
the repeated postponement by the EPA of deadlines for compliance with the
financial assurance portions of RCRA Subtitle D has significantly slowed growth
of the Company's landfill closure bond program, which was begun in March 1994
because of the anticipated deadline of April 1994 for universal compliance. Such
compliance currently is not anticipated to be universally mandated until after
April 1997.
 
  Inadequate Reinsurance Protection of Insurance Liabilities
 
     The Company depends heavily on reinsurers to assume a substantial portion
of the exposures underwritten by it. Failure by one or more reinsurers (which
are assuming risks from many sources over which the Company has no control)
could have a material adverse effect on the Company's performance, since the
Company would then be obligated to pay the failed reinsurer's portion of losses.
Moreover, the adequacy of reinsurance, even assuming the solvency of all
reinsurers, is a matter of estimation. As with pricing and reserving,
procurement of reinsurance is premised upon assumptions about the future based
upon past experience. Unanticipated events or trends could produce losses
inadequately covered by reinsurance.
 
  Market Reverses in Invested Asset Portfolio
 
     Investment of the Company's assets to balance its reserves and surplus is
critical to the maintenance of the Company's solvency and profitability. The
Company believes that many insurance companies earn far more in investment
returns on their portfolio assets than they do from underwriting; and many
companies actually underwrite at a loss to develop premium balances, hence
portfolio assets, for investment as evidenced by the number of insurers
operating at combined ratios in excess of 100%. The Company maintains an
investment policy of investing primarily in debt instruments of government
agencies and corporate entities with quality ratings of AA or better, and of
diversifying investments sufficiently to minimize the risk of a substantial
reverse or default in any one investment. These policies are articulated by a
written policy statement and overseen by a formal investment committee of senior
company officials. The Company also employs professional investment advisers to
counsel it with respect to its insurance and bonding operations on matters of
policy as well as individual investment transactions, although these advisers
have no discretionary authority to deploy the Company's assets. Notwithstanding
these measures, an aggregation of serious reverses
 
                                       10
   11
 
or defaults in the investment portfolio could have a material adverse effect on
the earnings and financial condition of the Company.
 
  Federal Income Taxes
 
     The Company accounts for federal income taxes in accordance with Statement
of Financial Accounting Standards No. 109. The Company has reduced the deferred
tax asset by a valuation allowance of CSC because the Company believes "it is
more likely than not" that the deferred asset would not be realized through
future taxable income. In reaching the Company's determination of the need to
provide a deferred tax valuation allowance, management considered all available
evidence, both positive and negative, as well as the weight and importance given
to such evidence. The negative factors the Company relied upon in determining
the need for the valuation allowance are that the CSC Group has a history of
significant portions of their taxable income coming from non-recurring
transactions, as well as the risks that CSC has in the areas of product pricing,
reserves, niche market competition and adequacy of reinsurance.
 
RISKS RELATED TO THE PROVISION OF BUSINESS CONSULTING AND MANAGEMENT SERVICES
 
  Competition
 
     The business consulting and management services industries have been highly
competitive in recent years resulting in the consolidation of many companies and
strategic alliances across industry lines. Competition is particularly acute for
small to medium sized providers because larger providers or strategic alliances
with larger providers can create service and price distortions in the market
place. The Company's business consulting and management services subsidiary has
historically endured these risks by maintaining a high level of development of
new services. There can be no assurance that future development efforts will
succeed or that intensifying competition will not outpace development efforts.
 
  Regulations
 
     The Company is vulnerable to legislative law changes with respect to its
provision of tax advisory, compliance and preparation services. Legislative
changes may expand or contract the types and amounts of business services that
individuals and businesses require. There can be no assurance that future laws
will provide the same or similar opportunities to provide business consulting
and management services to individuals and businesses that the current laws
provide.

                                  THE COMPANY
 
     The Company is a diversified services company which, acting through its
subsidiaries, provides specialty insurance services, business consulting and
management services, and waste and environmental services. In October 1996, the
Company completed the Merger Transactions, pursuant to which it acquired the CSC
Group, which includes three insurance companies, and CSU, an insurance agency
that markets surety bonds. See "Recent Developments." Through the Company's
insurance subsidiaries, the Company provides specialty insurance and bonding to
small and medium sized commercial enterprises in over forty states throughout
the United States.
 
     On December 1, 1996, the Company completed the acquisition of SMR. Through
SMR, the Company provides business consulting and management services in the
areas of tax planning, tax return preparation and compliance, computer
consulting, outsourcing, employee benefit program design and administration, and
human resource management to individuals and small and medium sized commercial
enterprises.
 
     The waste services the Company provides include hazardous and non-hazardous
waste treatment, storage and transportation services, disposal services and a
broad range of related environmental services including engineering, consulting
and analysis, remediation, groundwater/wastewater and other technical services.
The Company currently operates seven hazardous and non-hazardous waste TSD
Facilities located in the United States and Canada. These TSD Facilities are
serviced by the Company's integrated trucking operations. The Company does not
own any hazardous waste disposal sites.
 
     The Company was formed as a Delaware corporation in 1987 under the name
Stout Environmental, Inc. In 1992, the Company was acquired by RII. In April
1995, RII effected a spin-off of its hazardous waste operations through a
distribution of the Common Stock of the Company to the stockholders of record of
RII (the "Spin-off"). In connection with the Merger Transactions, in October
1996, the Company changed its name to International Alliance Services, Inc. from
Republic Environmental Systems, Inc. The Company's Common Stock trades on Nasdaq
under the trading symbol "IASI."
 
     The principal executive office of the Company is located at 10055 Sweet
Valley Drive, Valley View, Ohio, 44125 and its telephone number is (216)
447-9000.
 
                              RECENT DEVELOPMENTS
 
ACQUISITION OF ENVIRONMENTAL & COMMERCIAL INSURANCE AGENCY, INC.
 
     On November 6, 1996, the Company completed the acquisition of all of the
outstanding capital stock of ECI, a small, privately-held insurance agency based
in Columbus, Ohio, for $1.0 million in cash and 192,500 shares of Common Stock
that have not been registered under the Securities Act. ECI markets, through
over 100 independent agents, property and casualty insurance and surety bonds to
environmental remediation contractors, landfill operators, consultants, and
other small and medium sized companies specializing in environmental businesses
throughout the United States. For the year ended December 31, 1995 and the nine
month period ended September 30, 1996, ECI wrote approximately $14.0 million and
$11.1 million, respectively, in insurance premiums. Of the foregoing, $3.0
million and $2.2 million, respectively, were written on behalf of the CSC Group.
 
ACQUISITION OF SMR & CO. BUSINESS SERVICES
 
     On December 1, 1996, the Company completed the acquisition of all of the
outstanding shares of SMR, a company based in Cleveland, Ohio. SMR's gross
revenues for the fiscal year ended January 31, 1996 and the nine months ended
October 31, 1996, totaled approximately $6.0 million and $5.6 million,
respectively. Such amounts include approximately $300,000 of services sold to
the CSC Group during each of such periods. As consideration for such
acquisition, the Company issued 600,000 shares of Common Stock (the "SMR
Shares") and warrants to purchase an additional 900,000 shares of Common Stock
at an exercise price of $10.375 per share exercisable at any time, in whole or
in part, until November 30, 1999 (the "SMR Warrants" and, together with the SMR
Shares, the "SMR Securities"). The SMR Securities have not been
 
                                       12
   13
 
registered under the Securities Act. In addition, the resale of SMR Securities
by SMR is subject to a lock-up agreement under which SMR has agreed that it will
not sell, assign, transfer or otherwise dispose of, an aggregate of 15% of the
SMR Securities during the six-month period immediately following the date of
issuance and an aggregate of 85% of the SMR Securities for a two-year period
from the date of issuance.
 
ACQUISITION OF MIDWEST INDEMNITY CORPORATION
 
     On January 8, 1997, the Company completed the acquisition of the assets and
business of Midwest, a company based in Skokie, Illinois, in exchange for
approximately $3.3 million in cash, 407,246 shares of the Company's Common
Stock, and approximately $1.8 million in non-interest bearing notes payable in
installments through December 31, 1998. In the aggregate, the consideration paid
by the Company for the acquisition of certain of the assets and business of
Midwest had a market value as of the date of closing of such transaction of
approximately $9.9 million. Midwest markets environmental and surety bond
products throughout the United States through a system of approximately 75
independent agents and subagents. The acquisition is intended to expand the
geographic reach and breadth of the Company's environmental and surety business
from a regional to a national program.
 
     In conjunction with the acquisition of Midwest, several of the Company's
subsidiaries entered into a new strategic partnership with Gulf Insurance
Company of New York ("Gulf"). Under the terms of the partnership, (i) the
Company's subsidiary, CSU, was designated as the exclusive national underwriter
for Gulf's contract surety business, (ii) reinsurance arrangements were entered
into by certain of the Company's insurance company subsidiaries and (iii) a
subsidiary of the Company was designated to manage claims.
 
PRIVATE PLACEMENT TRANSACTION
 
     On December 30, 1996, the Company issued and sold 3,251,888 Units of the
Company for $9.00 per Unit. Each Unit consisted of one share of Common Stock and
one warrant to purchase one share of Common Stock of the Company at an exercise
price of $11.00 per share exercisable, in whole or in part, for a three-year
period from the date of issuance. The Private Placement resulted in net proceeds
of approximately $27.6 million, after deducting the placement agent fee and
other estimated expenses associated with the Private Placement.
 
     In addition, MGD Holdings and Messrs. Harve A. Ferrill and Richard C.
Rochon have entered into agreements to purchase an aggregate of 616,611 Units,
subject to stockholder approval. On January 6, 1997, the issuance of such Units
was approved by written consent of the holders of a majority of the outstanding
shares of Common Stock. In accordance with Rule 14c-2 under the Exchange Act,
the Company will prepare and file with the SEC, as soon as reasonably
practicable, a Schedule 14C Information Statement (the "Information Statement")
to be distributed to holders of the Company's Common Stock as of the date of
such written consent. The Information Statement will be used to notify such
holders of Common Stock of the action by written consent approving the issuance
of Units to MGD Holdings and Messrs. Ferrill and Rochon. In accordance with the
requirements of the Exchange Act, the issuance of Units to MGD Holdings and
Messrs. Ferrill and Rochon may not close earlier than 20 days following the
distribution of the Information Statement to such holders. Upon the closing of
the issuance of the Units to MGD Holdings and Messrs. Ferrill and Rochon, the
Company will receive an additional $5.3 million in proceeds. See "Risk
Factors -- Risks Related to the Company -- Strategy for Future Acquisitions;
Limited Operating History; Need for Substantial Additional Capital."
