Exhibit 99

                               RISK FACTORS


     In evaluating the Company and its business, prospective investors should
carefully consider, among other matters, the following factors:

     Attraction and Retention of Professional Personnel.  The Company's
ability to attract and retain qualified engineers, scientists and other
professionals, either through direct hiring or acquisition of other firms
employing such professionals, will be an important factor in determining the
Company's future success.  The market for these professionals is competitive,
and there can be no assurance that the Company will be successful in its
efforts to attract and retain such professionals.

     Potential Liability for Consulting Services Relating to Toxic and
Hazardous Materials and the Ability to Insure Such Risks.  The Company's
consulting services involve professional judgments about the nature of soil
conditions and other physical conditions, including the extent to which toxic
and hazardous materials are present, and about the probable effect of
procedures to mitigate problems or otherwise impact those conditions.  If
those judgments and recommendations based upon them do not result in the
anticipated consequences, losses to the Company's clients can occur for which
the Company may be liable.  In addition, the Company's projects often involve
hazardous and highly regulated material, the improper characterization,
handling, or disposal of which could constitute violations of Federal, state
or local statutes, and result in criminal fines and penalties.

     The Company, through a wholly owned subsidiary, insures the Company's
risks for professional liability, workers compensation, and general and
automobile claims up to certain policy limits.  Claims in excess of these
limits are covered by unrelated insurance carriers.  There also can be no
assurance that the dollar amount of the Company's liabilities will not
exceed the policy limits.

     Dependence on Environmental Regulation.  Much of the Company's business
is generated either directly or indirectly as a result of federal and state
laws, regulations and programs related to environmental issues.  United
States regulatory enforcement has weakened, and one of the key environmental
laws, the Comprehensive Environmental Response, Compensation and Liability
Act of 1980 ("Superfund"), did not receive congressional reauthorization.
Accordingly, a reduction of these laws and regulations, or changes in
governmental policies regarding the funding, implementation or enforcement of
the programs, could have a material adverse effect on the Company's business.
In addition, the laws and regulations often subject the Company to stringent
regulation in the conduct of its operations.  The principal environmental
legislation affecting the Company and its clients are:

     National Environmental Policy Act of 1969 ("NEPA")
     Resource Conservation and Recovery Act of 1976 ("RCRA")
     Comprehensive Environmental Response, Compensation and Liability Act of
       1980 ("Superfund") 
     The Superfund Amendments and Reauthorization Act of 1986 ("SARA")

Exhibit 99

                              RISK FACTORS
                              (continued)
                                
                                
     Although the liabilities imposed by the Superfund Act (and other
environmental legislation) are more directly related to the Company's
clients, they could, under certain circumstances, give rise to liability on
the part of the Company as a result of the Company's efforts in completing
client assignments that involve transportation or disposal of contaminated
samples or other hazardous materials belonging to its clients.  Liabilities
imposed by the Superfund Act can be joint and several where other parties
are involved.  In the opinion of management, it is unlikely that the Company's
activities will result in any liability under either the Superfund Act or
other environmental legislation in an amount which will have a material
adverse effect on the Company's results of operations or financial condition,
and management is not aware of any current activity by the Company which is
likely to result in any such liability.

     Competition.  The Company is engaged in highly competitive markets in
all of its service areas.  The Company competes with both large and small
firms; no single firm is dominant in any of the Company's primary service
areas.  Furthermore, given the expanding demand for the types of services
provided by the Company, it is likely that additional competitors will
emerge.  At the same time, a fair amount of consolidation is occurring in the
environmental business, particularly in the United States, due to mergers.
There can be no assurance that the Company's revenues and results of
operations will not at some point be adversely affected by these competitive
forces.

      Periodic fluctuations in general business conditions, demand for
those types of services provided by the Company, and foreign operations.
Much of the Company's business is dependent upon approvals of projects and/or
fundings.  Delays in these approvals do occur which can create overstaffing
that can result in an imbalance of costs to revenue.  The Company as a 
worldwide provider of services has operations in over 28 countries which 
exposes the Company to political, economic and other uncertainties such as
fluctuating currency values and exchange controls of the foreign countries.
