                                        the Years Ended December 31, 1997 and

INDEPENDENT AUDITORS' REPORT


To the Members Committee
Radian International LLC
Austin, Texas

We have audited the accompanying consolidated balance sheets of Radian
International LLC and subsidiaries (a Delaware limited liability company) (the
"Company") as of December 31, 1997 and 1996, and the related consolidated
statements of operations, members' equity, and cash flows for the years then
ended.  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, such consolidated financial statements present fairly, in all
material respects, the financial position of the Company at December 31, 1997
and 1996, and the results of its operations and its cash flows for the years
then ended in conformity with generally accepted accounting principles.

RADIAN INTERNATIONAL LLC
(A DELAWARE LIMITED LIABILITY COMPANY)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996
- --------------------------------------------------------------------------------

1.   BUSINESS AND ORGANIZATION

     BUSINESS - Radian International LLC and subsidiaries (the "Company") is an
     international engineering and technical services firm specializing in a
     broad range of engineering, environmental and remediation services to
     industry and governments worldwide.  The Company is headquartered in
     Austin, Texas, and employs approximately 2,000 people in 33 U.S. offices
     and 10 international offices.  Approximately 40% of the Company's revenues
     are from government agencies.

     ORGANIZATION - The Company was formed effective January 1, 1996 by The Dow
     Chemical Company ("Dow") and Dow Environmental, Inc. ("DEI"), a wholly
     owned subsidiary of Dow, together with the Hartford Steam Boiler Inspection
     and Insurance Company ("HSB") and Radian Corporation ("Radian"), a wholly
     owned subsidiary of HSB.  Dow, DEI, HSB and Radian entered into an
     agreement (the "Contribution Agreement") which called for the contribution
     of substantially all of DEI's and Radian's operating assets to the Company
     and the assumption of their related liabilities by the Company.  The
     related Limited Liability Company Agreement (the "LLC Agreement") formed
     the Company in Delaware as a limited liability company, owned 60% by Dow
     and 40% by HSB through December 31, 1999 and 65% by Dow and 35% by HSB,
     thereafter.  Dow and HSB (the "member companies") have limited personal
     liability for the obligations or debt of the Company, per the LLC
     Agreement, which allows for one class of member.

     HSB has an option from December 31, 1997 through December 31, 1998 to
     require Dow to purchase HSB's interest in the Company for a specified
     amount, as defined in the Contribution Agreement (see Note 18).

     The assets and liabilities were reflected in the Company's balance sheet at
     the book value of the member company contributing the asset or liability.
     A condensed summary of the net assets contributed under the Contribution
     Agreement at January 1, 1996 is as follows:


                                       
          Current assets                  $  78,538,733

          Other assets                       11,291,081

                                         -6-



2.   SIGNIFICANT ACCOUNTING POLICIES

     BASIS OF PRESENTATION - The consolidated financial statements include the
     accounts of the Company and its majority-owned subsidiaries.  All
     significant intercompany accounts and transactions have been eliminated in
     consolidation.  Related-party accounts receivable and accounts payable are
     incurred and settled in the normal course of business.  Net losses related
     to minority owners were $3,274 and $6,529 during 1997 and 1996,
     respectively.

     USE OF ESTIMATES - The preparation of the consolidated 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.

     CASH EQUIVALENTS - The Company considers all short-term cash investments
     with a maturity of three months or less at the time of purchase to be cash
     equivalents.

     INCOME RECOGNITION - The Company recognizes revenue from contracts as costs
     are incurred and includes estimated earned fees in the proportion of costs
     incurred to date to total estimated costs.  Revenues under certain
     government contracts may be increased or decreased in accordance with cost
     or performance incentive provisions which measure actual performance
     against established targets or other criteria.  Such incentive fee awards
     are included in revenue at the time the amounts can be determined.
     Provision is made for losses on contracts at the time such losses become
     known.  Income from other sales is recognized when earned.

     INVESTMENT SECURITIES - The Company classifies investment securities held
     in mutual funds as available-for-sale.  Accordingly, these investments,
     which are included in other assets, are carried at their fair market value,
     with net unrealized gains and losses included in members' equity; however,
     unrealized losses that are other than temporary are recognized in earnings.

     FAIR VALUE OF FINANCIAL INSTRUMENTS - The fair value of the Company's
     financial instruments, such as cash, cash equivalents, accounts receivable,
     accounts and notes payable and accrued liabilities, approximate carrying
     values at December 31, 1997 and 1996.  The long-term debt and note payable
     to members, although with related parties, are at floating interest rates
     and management believes the carrying value approximates fair value for this
     debt.  At December 31, 1997 and 1996, other current assets included notes
     receivable of $1,182,024 and $1,446,459, respectively, related to the sale
     of the Company's Environmental Protection Agency business.  The fair value
     of these notes, based on current market interest rates, was $1,304,065 and
     $1,604,000 at December 31, 1997 and 1996, respectively.

     PROPERTY AND DEPRECIATION AND AMORTIZATION - Property is carried at cost
     less accumulated depreciation.  Depreciation is calculated on equipment and
     vehicles on the basis of its estimated useful life (ranging from 3 to 15
     years) using both straight-line and accelerated methods.  Leasehold
     improvements are amortized over the term of the lease or the estimated
     useful life, if shorter.  Upon retirement or replacement of an asset, gain
     or loss is included in operations.

     GOODWILL AND AMORTIZATION - Goodwill is amortized using the straight-line
     method over periods ranging from five to forty years.  The Company
     periodically assesses the recoverability of goodwill by determining that
     the estimated undiscounted future cash flows are sufficient to recover the
     asset's carrying amount.  When it is probable that undiscounted future cash
     flows will not be sufficient to recover the net carrying amount, such 
     excess amounts will be written off (see Note 17).


                                         -7-


     INVENTORIES - Inventories are stated at the lower of cost or market.  The
     dollar value weighted average and first-in first-out methods are used to
     determine the cost of inventories.  The Company's inventories consist
     primarily of chemicals, computer components and gold.

     RESEARCH AND DEVELOPMENT - Research and development costs, which are
     charged to operations as incurred, aggregated approximately $1,114,858 and
     $1,488,697 in 1997 and 1996, respectively.

     TRANSLATION OF FOREIGN CURRENCIES - Assets and liabilities of foreign
     subsidiaries are translated at the rate of exchange in effect on the
     balance sheet date; income and expenses are translated at the average rates
     of exchange prevailing during the year.  The related translation adjustment
     is reflected in members' equity.

     INCOME TAXES - The Company is classified as a partnership for federal
     income tax purposes and as such, any federal taxable income or loss
     generated will be included in the tax returns of the member companies.  The
     Company has four US subsidiaries which file separate federal tax returns
     and the Company files separate state income tax returns.  Foreign
     subsidiaries file separate returns in their respective countries.  In
     accordance with Statement of Financial Accounting Standards ("SFAS")
     No. 109, "Accounting for Income Taxes," income taxes are recognized for
     (a) the amount of taxes payable or refundable for the current year and
     (b) the net change in deferred tax liabilities and assets to be recognized
     in the future.

     RECLASSIFICATIONS - Certain reclassifications of previously reported 1996
     amounts have been made to be consistent with 1997 classifications.  Such
     reclassifications have no effect on net income.

9.   LONG-TERM DEBT AND NOTES PAYABLE

     The Company maintains an uncollateralized revolving credit agreement with
     Dow which, at December 31, 1997, provided for borrowings of up to $50
     million.  At December 31, 1997, $35,692,553 was outstanding under this
     agreement.  Interest is payable quarterly, at Dow's LIBOR rate plus 1/8%
     (5.85% at December 31, 1997); the principal is due on December 31, 1998.
     At December 31, 1996, such amounts were classified as long-term debt based
     on the maturity date then in effect.  As of December 31, 1997 and 1996,
     foreign subsidiaries have borrowed $2,189,828 and $979,266, respectively,
     from local Dow affiliates under Intercompany Revolving Loan Agreements.
     The loans have no maturity date and bear interest at local market rates and
     are included in short-term borrowings in the accompanying balance sheets.

     During 1997, the Company terminated a $5 million uncollateralized
     short-term line of credit with a bank which had never been utilized.  The
     line of credit was guaranteed by the members and provided for interest at
     the bank's prime lending rate less 1%.

     The Company has available letters of credit in the amount of $684,910,
     expiring from June 1998 through January 2000.

     At December 31, 1996, the Company had an uncollateralized note payable of
     $9,459,941 with HSB, providing interest at HSB's weighted average
     short-term bank borrowing rate, plus 0.5% (6.10% as of December 31, 1996).
     This note was paid in full during 1997.

     Maturities of long-term debt and notes payable for the five years
     subsequent to December 31, 1997 follow:

     At December 31, 1997 and 1996, deferred tax assets and liabilities included
     in other current assets and other long-term liabilities, respectively,
     comprised the following:



                                                  DECEMBER 31,
                                        ------------------------------

                                         -----------       -----------


     The temporary differences which result in deferred tax assets and
     liabilities are primarily depreciation, benefit plan expenses, and
     restructuring expenses.

     The Company does not provide for taxes which would be payable if
     undistributed earnings of its foreign subsidiaries were remitted because it
     is the Company's intent to reinvest the undistributed earnings
     indefinitely.  At December 31, 1997 and 1996, the accumulated undistributed
     earnings were not significant.

     As of December 31, 1997 and 1996, a valuation allowance of $667,296 was
     recorded for the net operating loss carryfowards of foreign subsidiaries
     due to the uncertainty of recovery of the benefit.

     income of $1,924,819 and $310,888, respectively.

12.  EMPLOYEE BENEFITS PLANS

     During 1996, the Company's employees participated in the benefit plans of
     DEI and Radian until new plans were established.  The plan descriptions are
     as follows:

     DEI DEFINED CONTRIBUTION PLAN - DEI sponsored a 401(k) plan which covers
     substantially all employees.  Under the provisions of the plan, the Company
     contributed the greater of $800 or 2% of the employee's salary up to the
     first $60,600.  For amounts earned in excess of $60,600, DEI contributed 4%
     of the employee's salary.  In addition, participating employees could defer
     up to 15% of annual compensation of which DEI would match 50% up to the
     first 4% of the participants' eligible compensation. Company contributions
     under the plan were $225,500 in 1996.  Effective April 1, 1996, the
     participants in this plan became participants in the Radian 401(k) plan and
     this plan was terminated.

     DEI STOCK PURCHASE PLAN - DEI had a stock purchase plan that allowed
     participating employees to purchase, through payroll deductions, shares of
     Dow's common stock at the lower of the plan price or market price on the
     last day of trading prior to April 1, 1996.  The plan was terminated
     January 31, 1996, and the Company made no contributions in 1996.

     DEI SUPPLEMENTAL OFFICER RETIREMENT PLAN - DEI maintained an unfunded,
     nonqualified deferred compensation plan for its officers.  Under provisions
     of the plan, participating officers could defer up to 100% of their bonus
     and 15% of their salary to the plan, offset by the percentage deferred into
     the qualified 401(k) plan.  DEI matched these contributions at the
     percentage matched for the qualified 401(k) plan and provided a basic
     contribution without regard for Internal Revenue Service Code limitation
     and reduced by amounts actually contributed in the 401(k) plan.  Interest
     is earned and credited to the participant's account twice a year.  This
     plan was frozen effective January 1, 1996.

     Radian 401(k) PLAN - Radian maintained an employee thrift plan which
     qualifies under section 401(k) of the Internal Revenue Code.  The plan is a
     defined contribution plan.  Effective April 1, 1996, this plan was amended
     and restated as the Radian International LLC 401(k) Thrift Plan and all
     employees of the Company who meet the service requirements specified in the
     plan are eligible for participation.  Under the


                                         -13-



     provisions of the thrift plan, participating employees may defer up to 10%
     of annual compensation.  The Company matches 75% of the contributions, but
     not in excess of 6% of the participants' eligible compensation.  Company
     contributions under the plan were $4,936,281 and $5,186,200 in 1997 and
     1996, respectively.

     SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN AND SALARY CONTINUATION AGREEMENT -
     Radian maintained an unfunded supplemental executive retirement plan
     ("SERP") and an unfunded salary continuation agreement for certain
     executives.  The plans provide for benefits which supplement those provided
     by the Company's other benefit plans.  The salary continuation plan is
     recorded in accordance with SFAS No. 87, "Employers' Accounting for
     Pensions."  At December 31, 1997 and 1996, the Company had designated and
     deposited $4,858,843 and $4,102,840, respectively, in a trust account for
     the SERP.

     In accordance with the provisions of SFAS No. 87, the Company was required
     to record an additional minimum liability at December 31, 1997 and 1996.
     This amount represents the excess of the accumulated benefit obligations
     over the fair value of plan assets to the extent possible because the asset
     recognized may not exceed the amount of unrecognized prior service cost.
     The balance of the liability at the end of each period is reported as a
     component of members' equity, net of applicable taxes.  At December 31,
     1997 and 1996, the cumulative additional minimum liability was $1,071,614
     and $1,394,089, respectively.

     The present value of accumulated benefits as of December 31, 1997 and 1996,

     POSTRETIREMENT BENEFITS - The Company provides certain medical insurance
     benefits to eligible retired employees.  The defined-benefit plan covers
     substantially all employees.  The plan for all retirees allows for a
     reimbursement credit of up to $50 per month for medigap premiums.  Eligible
     retirees for the medigap plan must meet minimum active service
     requirements.  The plan is unfunded.

     The Company has adopted SFAS No. 106, "Employers' Accounting for
     Postretirement Benefits Other Than Pensions."  This standard requires that
     the expected cost of retiree benefits be charged to expense during the
     years that the employees render service rather than the Company's past
     practice of recognizing these costs on a cash basis.

     The plan's combined funded status at December 31, 1997 and 1996 is as
     follows:



                                                                               1997         1996

     Net periodic postretirement benefit cost for 1997 and 1996 included the

                                         -15-


     The weighted-average discount rate used in determining the APBO was 7.25%
     in 1997 and 1996.  The effect of a one percent increase in the assumed
     health care cost trend rates would be to increase the accumulated
     postretirement benefit obligation and the aggregate of the service cost and
     interest cost by $7,894 and $565, respectively.

     During 1996, the Company sold two business units.  The reduction of
     employees which resulted from the sale of these business units was treated
     as a plan curtailment.  The curtailment resulted in a reduction of the
     accrued postretirement benefit of $20,000.

     POSTEMPLOYMENT BENEFITS - The Company has adopted SFAS No. 112, "Employer's
     Accounting for Postemployment Benefits."  The accumulated postemployment
     benefit obligation was $493,578 and $217,607 as of December 31, 1997 and
     1996, respectively.

     SIGNIFICANT ESTIMATES - At December 31, 1997, the Company has recorded an
     obligation for the supplemental executive retirement plan, salary
     continuation agreement, postretirement and postemployment benefits of
     $7,367,716, of which $838,073 is included in accrued payroll and related
     items.  At December 31, 1996, such amounts were $6,082,686 and $217,607,
     respectively.  Significant assumptions used in determining the obligation
     and related expense include discount rates, rate of increase for future
     compensation, withdrawals, mortality and retirement rates and expected
     claim costs.

13.  RELATED PARTY TRANSACTIONS

     The Company recognized $41,702,311 and $38,092,362 of revenue from member
     companies in 1997 and 1996, respectively.  Interest expense on member
     company debt aggregated $2,380,645 and $1,595,879 in 1997 and 1996,
     respectively.  During 1997 and 1996, certain Dow employees provided
     technical and engineering services to the Company under a Technology
     Services Agreement.  The amounts charged by Dow related to this agreement
     during 1997 and 1996 were $681,000 and $2,015,589, respectively.  At
     December 31, 1997 and 1996, accounts payable and accrued liabilities
     included $3,805,823 and $5,003,522, respectively, in amounts owed to Dow
     for technical services, administrative services, and facility costs.  See
     Note 5 for information regarding amounts due from members included in
     accounts receivable.

14.  RESTRUCTURING AND TERMINATION ACCRUALS

     In December 1996, the Company's management approved a restructuring of the
     Company and a realignment of the current workforce which resulted in the
     termination of 110 employees.  The termination payments of $3,443,000,
     which were substantially paid out during 1997, were accrued as of
     December 31, 1996 as a component of general and administrative expenses.

     During 1997, the Company reorganized its operations, resulting in the
     termination of approximately 50 employees.  The termination payments of
     $3,149,000, which will be substantially paid out within 1998, were accrued
     as of December 31, 1997 as a component of general and administrative
     expenses.  Additionally, at December 31, 1997, the Company accrued
     $2,001,000 related to amounts to be paid to three former executives under
     consulting agreements.

15.  SALE OF BUSINESS UNITS

     On June 14, 1996, the Company sold the contracts and certain fixed assets
     related to its Environmental Protection Agency business for $1,105,000 in
     cash and a note receivable of $1,446,759.  A gain of $1,828,153 was
     recognized.  The sale agreement provides for an adjustment to the sales
     price, based on


                                         -16-



     revenues earned on the sold contracts through July 15, 2001.  Through
     December 31, 1997, there were no downward revisions of the sales price and
     management believes that the future performance of the contracts will be
     adequate to prevent any such revisions.

     On March 29, 1996, the Company sold its electronic assembly services unit
     for $2,000,000.  A gain of $528,909 was recognized.

     On April 7, 1997, the Company sold its electronic paneling services unit
     for $2,600,000.  No gain or loss was recognized.

16.  CONTINGENCIES

     The Company is involved in various legal matters arising in the normal
     course of business.  In management's opinion, the Company's ultimate
     liability or loss, if any, resulting from such legal matters will not have
     a material adverse effect on its financial position.

     The Company's contracts with the U.S. government are subject to examination
     by the Defense Contract Audit Agency ("DCAA").  Contracts and other records
     of the Company have been examined and reported upon by the DCAA through
     December 31, 1994.  Management of the Company believes that adjustments, if
     any, resulting from potential renegotiation proceedings for years
     subsequent to 1994 will have no significant impact on the Company's
     financial condition or results of operations.

     The Company is self-insured up to certain limits for employee health
     benefits.  Therefore, the financial statements include a reserve for claims
     incurred.  The Company also retains a portion of risk for casualty losses.

17.  GOODWILL

     At December 31, 1997 and 1996, goodwill comprised the following:



                                     1997              1996

                                -------------     -------------


     During 1997, the Company recorded an impairment write-down of $7,246,007 in
     general and administrative expenses related to the goodwill associated with
     Ecobilan S.A.  Projected levels of business used to determine the purchase
     price of Ecobilan S.A. have not been achieved and management does not
     believe that the anticipated future activities support the recorded balance
     of goodwill.  The impairment amount was calculated using discounted future
     cash flows.

18.  SUBSEQUENT EVENT

     On January 2, 1998, HSB exercised its option to require Dow to repurchase
     its ownership interest in the Company.  Effective that date, TCM
     Technologies, Inc., a wholly owned subsidiary of Dow, purchased HSB's
     ownership interest.
