                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                    UNAUDITED

               FOR THE THREE AND SIX MONTHS ENDED JANUARY 31, 1998


1.      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

OPINION OF MANAGEMENT

In the opinion of Management, the accompanying unaudited consolidated financial
statements contain all adjustments of a normal and recurring nature necessary to
present fairly the financial position of Veritas DGC Inc. and subsidiaries at
January 31, 1998, and the results of its operations and its cash flows for the
three and six months ended January 31, 1997 and 1998. The results of operations
for any interim period are not necessarily indicative of the results to be
expected for a full year. Results could be affected by changes in demand for
geophysical services and products, which is directly related to the level of oil
and gas exploration and development activity. Governmental actions, foreign
currency exchange rate fluctuations, seasonal factors, weather conditions and
equipment problems also could impact future operating results.

NEW ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive
Income." This statement requires disclosure in both interim and annual reporting
of the reporting period's comprehensive income (changes in equity from non-owner
sources), net of the related tax effect, on the face of the consolidated
statement of income, consolidated statement of changes in stockholders' equity
or in a separate statement of comprehensive income and the accumulated balance
of other comprehensive income (comprehensive income excluding net income) as a
separate component in the stockholders' equity section of the consolidated
balance sheet. Classifications included in the accumulated balance may be
disclosed on the face of the consolidated balance sheet, statement of changes in
stockholders' equity or in notes to the consolidated financial statements. The
Company's sources of comprehensive income include net income and cumulative
foreign currency translation adjustments. The Company will be required to
implement this statement in fiscal year 1999. Management has not completed its
assessment of how it will present the required information.

In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information," which will supersede SFAS No. 14,
"Financial Reporting for Segments of a Business Enterprise." It will require the
Company to disclose certain financial information in both annual and interim
reporting about "operating segments" which are components of a company that are
evaluated regularly by management in deciding how to allocate its resources and
in assessing its performance. It also requires disclosure about the countries
from which the Company derives its revenues and in which it employs its
long-lived assets. Major customers will continue to be disclosed. The Company
will be required to implement this statement in fiscal year 1999. Management has
not completed its assessment of how the adoption of this statement will affect
its existing segment disclosures.

The senior notes are due in October 2003 with interest payable semi-annually at
9 3/4%. The senior notes are unsecured and are effectively subordinated to
secured debt of the Company with respect to the assets securing such debt and to
all debt of its subsidiaries whether secured or unsecured. The indenture
relating to the senior notes contains certain covenants which limit the
Company's ability to, among other things, incur additional debt, pay dividends,
and complete mergers, acquisitions and sales of assets. Upon a change in control
of the Company, as defined in the indenture, the holders of the senior notes
have the right to require the Company to purchase all or a portion of such
holder's senior note at a price equal to 101% of the aggregate principal amount.
The Company has the right to redeem the senior notes, in whole or part, on or
after October 15, 2000. Under certain conditions, the Company may redeem up to
$20.0 million in aggregate principal amount of the senior notes prior to October
15, 1999.

The Company maintains a revolving credit agreement which matures in July 1998
with a commercial bank and provides advances up to $25.0 million of which $20.0
million are secured by substantially all of the receivables of the Company.
Advances bear interest, at the Company's election, at LIBOR plus two percent or
prime rate and are defined by a borrowing formula. Covenants in the agreement
limit, among other things, the Company's right, without consent of the lender,
to take certain actions, including creating indebtedness and paying dividends,
and limit the Company's capital expenditures in any fiscal year. In addition,
the agreement requires minimum cash flow coverage and the maintenance of minimum
tangible net worth, limits the ratio of funded debt to total capitalization, and
requires the Company to maintain a minimum current ratio.

4.    OTHER ACCRUED LIABILITIES

Other accrued liabilities included $8.3 million and $7.2 million of accrued
payroll and benefits and $14.3 million and $30.8 million of deferred revenues as
of July 31, 1997 and January 31, 1998, respectively.

5.      EMPLOYEE STOCK PURCHASE PLAN

On November 1, 1997, the Company initiated a noncompensatory employee stock
purchase plan for up to 500,0000 shares of common stock. Participation is
voluntary and substantially all full-time employees meeting limited eligibility
requirements may participate. Contributions are made through payroll deductions
and may not be less than 1% or more than 15% of the participant's base pay as
defined. Options are deemed to be granted on the first day and exercised on the
last day of the fiscal quarter at a price which is the lower of 85% of the
market price on the first or last day of the fiscal quarter.

Exchangeable Stock issued in the business combination between Veritas DGC Inc.,
formerly Digicon Inc., and Veritas Energy Services Inc. is included in both
computations. Options to purchase 49,461 common shares at exercise prices
ranging from $38 1/8 to $45 5/16 and expiring March 2007 have been excluded from
the computation assuming dilution for the three and six months ended January 31,
1998 because the options' exercise prices exceeded the average market price of
the underlying common shares.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

This report contains forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in the forward-looking statements as a result of certain factors
which are more fully described in other reports filed with the Securities and
Exchange Commission and include changes in market conditions in the oil and gas
industry as well as declines in prices of oil and gas.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JANUARY 31, 1998 COMPARED WITH THREE MONTHS ENDED 
JANUARY 31, 1997

Revenues. Revenues increased 36% from $90.7 million to $123.6 million during the
current quarter. Increases were recorded by all service groups; however, marine
acquisition revenues showed the largest increase of 95% from $12.9 million to
$25.2 million primarily due to additional streamer capacity resulting from the
upgrade to Syntron equipment in the prior fiscal year and the increase in demand
for and higher prefunding commitments on multi-client surveys performed.

Multi-client data sales increased 49% from $16.2 million to $24.2 million due to
expanding customer interest in the Gulf of Mexico deepwater and sub-salt areas.
Over the past two years, as oil and gas companies have moved toward multi-client
surveys to reduce finding costs in these areas, the Company has significantly
increased its data library inventory.

Data processing revenues increased 26% from $18.1 million to $22.8 million due
to increased market activity, increased demand for computer intensive processes,
such as prestack time and depth migration, and increased demand for processing
the larger volumes of data acquired in three dimensional surveys. The Company
has substantially upgraded its processing centers, including the addition of a
NEC supercomputer in the U.K. in August 1997, to meet this increased demand.

Land and transition zone acquisition revenues increased 18% from $43.5 million
to $51.4 million as a result of firm prices, additional recording capacity and
operating efficiencies from upgraded and standardized equipment.

Operating Expenses. Costs of services increased 19% from $68.0 million to $80.8
million, but as a percent of revenues decreased from 75% to 65%. The improvement
in operating margins is mainly attributable to the significant sales of
multi-client data surveys that generally have higher margins. Data processing
operating margins also improved as a result of an increase in capacity of more
efficient computers and software. Marine margins were consistent and land and
transition zone margins decreased slightly as a result of an unusually warm
winter season in Canada.

Depreciation and Amortization. Depreciation and amortization expense increased
32% from $9.8 million to $13.0 million due to capital expenditures of $137.0
million over the last eighteen months.

Selling, General and Administrative. Selling, general and administrative
expenses increased 75% from $2.4 million to $4.3 million, resulting primarily
from costs incurred in implementing new administrative and accounting systems
and pursuing a more aggressive marketing strategy.

Other Income. Other income increased $1.3 million primarily from interest income
earned on the higher average cash balances maintained by the Company.

Income Taxes. Provision for income taxes increased from $1.7 million to $6.5
million as a result of the increased profitability of the Company.

Equity in earnings. Equity in earnings is related to the Indonesian joint
venture. More marine acquisition surveys were performed in the prior year that
increased profitability of the joint venture.

SIX MONTHS ENDED JANUARY 31, 1998 COMPARED WITH SIX MONTHS ENDED 
JANUARY 31, 1997

Revenues. Revenues increased 59% from $167.1 million to $265.8 million during
the current period. Although all service groups improved, multi-client data
sales showed the largest increase at 226% from $20.4 million to $66.5 million.
Sales of Gulf of Mexico data were the largest contributor.

Marine acquisition revenues increased 49% from $29.2 million to $43.5 million
primarily due to additional streamer capacity and an increase in demand.

Data processing revenues increased 35% from $33.5 million to $45.1 million due
to increases in market activity, computer intensive processes and capacity.

Land and transition zone acquisition revenues increased 32% from $84.0 million
to $110.7 million as a result of firm prices, additional recording capacity and
operating efficiencies from upgraded and standardized equipment.

Operating Expenses. Costs of services increased 38% from $126.3 million to
$174.1 million, but as a percent of revenues decreased from 76% to 66%. The
improvement in operating margins is mainly attributable to significant sales of
multi-client data surveys. Data processing operating margins also showed
improvement as a result of more efficient equipment. Marine and land and
transition zone margins remained consistent.

Depreciation and Amortization. Depreciation and amortization expense increased
37% from $18.5 million to $25.5 million due to the large increase in capital
expenditures over the past eighteen months.

Selling, General and Administrative. Selling, general and administrative
expenses increased 101% from $4.4 million to $8.8 million resulting primarily
from costs incurred in implementing new administrative and accounting systems
and pursuing a more aggressive marketing strategy.

Interest. Interest expense increased slightly from $3.2 million to $4.1 million
due to the issuance of $75.0 million of senior notes in late October 1996 which
replaced approximately $40.0 million in other debt.

Other Income. Other income increased $1.3 million primarily from interest income
earned on the higher average cash balances maintained by the Company.

Income Taxes. Provision for income taxes increased from $2.9 million to $16.2
million as a result of the increased profitability of the Company. This increase
was offset by a benefit of $7.2 million, recorded to recognize the expected
future utilization of tax net operating loss carryforwards.

LIQUIDITY AND CAPITAL RESOURCES

The Company's internal sources of liquidity are cash, short-term investments and
cash flow from operations. External sources include the unutilized portion of a
revolving credit facility, public financings, equipment financing and trade
credit.

The Company requires significant amounts of working capital to support its
operations and to fund capital spending and research and development programs.
The Company's foreign operations require greater amounts of working capital than
similar domestic activities, as the average collection period for foreign
receivables is generally longer than for comparable domestic accounts.
Approximately 52% of revenues for the quarter ended January 31, 1998 were
attributable to the Company's foreign operations. In addition, the Company has
increased its participation in multi-client data surveys and has significantly
expanded its library of multi-client data. Because of the lead-time between
survey execution and sale, partially funded multi-client data surveys generally
require greater amounts of working capital than contract work. Depending on the
timing of future sales of the data and the collection of the proceeds from such
sales, the Company's liquidity will be affected; however, the Company believes
that these non-exclusive surveys have good long-term sales, earnings and cash
flow potential.

The Company's capital expenditure program for 1998 is $104.0 million and
includes expenditures of $26.0 million to maintain or replace the Company's
current operating equipment and $78.0 million to 



                                       10
<PAGE>   13
expand capacity, including the purchase of a marine seismic vessel previously
chartered and the outfitting of a new marine seismic vessel. The Company plans
to spend $6.2 million in fiscal 1998 for research and development.

In October 1996, the Company completed a $75.0 million public offering of Senior
Notes due in October 2003 (the "Senior Notes"). The net proceeds from the Senior
Notes were used to retire outstanding indebtedness of the Company and fund a
portion of the Company's capital expenditures in fiscal 1997. The indenture
relating to the Senior Notes (the "Indenture") contains certain covenants,
including covenants that limit the Company's ability to, among other things,
incur additional debt, pay dividends, and complete mergers, acquisitions and
sales of assets. The Company is in compliance with all covenants of the
agreement at January 31, 1998. Upon a change in control of the Company (as
defined in the Indenture), holders of the Senior Notes have the right to require
the Company to purchase all or a portion of such holder's Senior Note at a price
equal to 101% of the aggregate principal amount. Interest is payable
semi-annually.

In July 1997, the Company completed a public offering (the "Offering") of
3,450,000 shares of common stock . A portion of the net proceeds from the
Offering of $76.4 million was used for 1997 and 1998 capital expenditures and
the remainder will be used for other general corporate purposes, including
working capital, possible repurchases of outstanding Senior Notes and possible
acquisitions. No repurchases will be made of outstanding Senior Notes, except at
prices which are, at the time of any such repurchase, regarded by the Company to
be attractive. Accordingly, there can be no assurance that any such repurchases
will be made. While the Company regularly evaluates opportunities to acquire
complementary businesses, it has no present agreements or commitments with
respect to possible acquisitions, and no estimate can be made as to the amount
of net proceeds which ultimately may be used for acquisitions.

The Company maintains a $25.0 million revolving credit facility, as amended (the
"Credit Facility"), with a commercial bank which will mature in July 1998.
Advances up to $20.0 million under the Credit Facility are secured by
substantially all of the Company's receivables. All advances bear interest, at
the Company's election, at LIBOR plus two percent or prime rate and are defined
by a borrowing formula which, based on current levels of receivables, results in
a borrowing base well in excess of the maximum commitment. Covenants in the
Credit Facility prohibit the payment of cash dividends and limit, among other
things, the Company's right to create indebtedness and make capital expenditures
over a certain amount in any fiscal year. In addition, the Credit Facility
requires minimum cash flow coverage and the maintenance of minimum tangible net
worth, limits the ratio of funded debt to total capitalization, and requires the
Company to maintain a minimum current ratio. The Company is in compliance with
all covenants of the agreement and has no outstanding advances at January 31,
1998.

Since the Company's quasi-reorganization with respect to Digicon Inc. on July
31, 1991, the tax benefits of net operating loss carryforwards existing at the
date of the quasi-reorganization have been recognized through a direct addition
to paid-in capital, when realization is more likely than not. Additionally, the
utilization of the net operating loss carryforwards existing at the date of the
quasi-reorganization is subject to certain limitations. During the six months
ended January 31, 1998 the Company recognized $4.8 million related to these
benefits, due to the increased profitability of the Company during the current
fiscal year and anticipated profitability in future fiscal years.

The Company is currently assessing the impact of the year 2000 issue relating to
computer systems but does not expect future results to be affected.

The Company will require substantial cash flow to continue operations on a
satisfactory basis, complete its capital expenditure and research and
development programs and meet its principal and interest obligations with
respect to outstanding indebtedness. The Company anticipates that cash and
short-term investments, net proceeds from the Offering, cash flow generated from
operations and borrowings permitted under the Indenture and Credit Facility will
provide sufficient liquidity to fund these requirements through fiscal 1998.
However, the Company's ability to meet its debt service and other obligations
depends on its future performance, which, in turn, is subject to general
economic conditions, 




                                       11

business and other factors beyond the Company's control. If
the Company is unable to generate sufficient cash flow from operations or
otherwise to comply with the terms of the Credit Facility or the Indenture, it
may be required to refinance all or a portion of its existing debt or obtain
additional financing. There can be no assurance that the Company would be able
to obtain such refinancing or financing, or that any refinancing or financing
would result in a level of net proceeds required.
