     Dear Veritas DGC Inc. Stockholder and Veritas Energy Services Inc.
Exchangeable Shareholder:
 
     You are cordially invited to attend a special meeting of the stockholders
of Veritas DGC Inc. ("Veritas DGC"), including the holders of exchangeable
shares of Veritas Energy Services Inc. ("VESI"), a wholly-owned subsidiary of
Veritas DGC, to be held on           ,           , 1999 at           (local
time), at Veritas DGC's offices located at 3701 Kirby Drive, Houston, Texas
77098.
 
     The special meeting is important because we are asking you to approve a
proposal to amend our Restated Certificate of Incorporation (the "Charter
Amendment") to authorize a new series of special voting stock and to eliminate
provisions that restrict the issuance of certain securities. Upon approval of
these changes, we plan to acquire Enertec Resource Services Inc. ("Enertec"), a
company based in Alberta, Canada, pursuant to a Combination Agreement between
Veritas DGC, VESI and Enertec dated March 30, 1999. Following the transaction,
Enertec will be wholly-owned by VESI, and all of the former holders of Enertec
common shares will hold Series 1 Exchangeable Shares issued by VESI. The details
of the proposed transaction are included in the Joint Proxy Statement. Also
included is a form of proxy. Please review the Joint Proxy Statement carefully
as it has been prepared to help you make an informed decision.
 
     Your board of directors has unanimously approved the Charter Amendment. The
board recommends that you vote FOR the Amendment. If the Charter Amendment is
not approved, the acquisition of Enertec cannot be closed. YOUR VOTE IS
IMPORTANT.
 
     Even if you do not attend the special meeting, it is important that your
shares be voted. Please vote by promptly completing and mailing the enclosed
proxy card so that your shares will be represented at the special meeting and
voted as you wish.
 
                                          Sincerely,
 
                                          David B. Robson,

     Notice is given that a special meeting of the stockholders of Veritas DGC
Inc. ("Veritas DGC"), including the holders of exchangeable shares of Veritas
Energy Services Inc. ("VESI"), a wholly-owned subsidiary of Veritas DGC, will be
held at the offices of Veritas DGC, 3701 Kirby Drive, Houston, Texas 77098, on
          ,           , 1999 at           (local time), for the following
purposes:
 
        1. To consider and vote upon amendments to Veritas DGC's Restated
           Certificate of Incorporation to, among other things, designate a new
           series of special voting stock consisting of one share and eliminate
           certain restrictive provisions regarding the issuance of additional
           series of ordinary shares; and
 
        2. To transact such other business as may properly be presented to the
           special meeting.
 
     Veritas DGC, VESI and Enertec Resource Services Inc. will not be able to
close the Combination Agreement described in the Joint Proxy Statement if the
Veritas DGC stockholders and the VESI exchangeable stockholders do not approve
the proposal to amend the Restated Certificate of Incorporation.
 
     Stockholders of record as of the close of business on           , 1999,
will be entitled to notice of and to vote at the special meeting. A
stockholders' list will be available on           , 1999, and may be inspected
during normal business hours prior to the special meeting at the offices of
Veritas DGC, 3701 Kirby Drive, Houston, Texas 77098.
 
     If you do not expect to be present at the special meeting, please sign and
date the enclosed proxy and return it promptly in the enclosed stamped envelope.
The prompt return of proxies will ensure a quorum and save the company the
expense of further solicitation.

Dear Exchangeable Shareholder:
 
     You are cordially invited to attend a special meeting of the exchangeable
shareholders of Veritas Energy Services Inc. ("VESI") to be held on           ,
          , 1999 at           (Calgary time) at           , Calgary, Alberta,
Canada.
 
     The special meeting is important because we are asking you to approve an
arrangement which will lead to a combination of Enertec Resource Services Inc.
("Enertec"), VESI and your parent company, Veritas DGC Inc. ("Veritas DGC"). The
arrangement also includes amendments to certain terms of the VESI Exchangeable
Shares which are necessary for completion of the combination and would allow
Veritas DGC and VESI to complete transactions of a similar type in the future
without the approval of the holders of VESI Exchangeable Shares.
 
     The details of the proposed transaction are included in the Joint Proxy
Statement. Also included is a form of proxy. Please review the Joint Proxy
Statement carefully as it has been prepared to help you make an informed
decision.
 
     If the proposed transaction is completed, Enertec shareholders will
transfer each of their Enertec common shares to VESI and the sole consideration
received therefor will be 0.345 of a Series 1 Exchangeable Share (a
newly-created class of shares) of VESI. Each Series 1 Exchangeable Share is
exchangeable for one share of Veritas DGC common stock.
 
     Following the transaction, Enertec will be wholly-owned by VESI, and all of
the former holders of Enertec common shares will hold Series 1 Exchangeable
Shares issued by VESI.
 
     David B. Robson, president of VESI and chairman and chief executive officer
of Veritas DGC, and the holder of approximately 86% of the outstanding VESI
Exchangeable Shares entitled to vote, has agreed to vote in favor of the
arrangement with Enertec. As such, approval of the VESI proposal is effectively
assured.
 
     Your board of directors has unanimously recommended that you vote in favor
of the special resolution concerning the arrangement and the combination of
Veritas DGC, VESI and Enertec.
 
     We hope that you will be able to attend the special meeting. However, if
you are unable to attend the special meeting in person, we urge you to complete
the enclosed form of proxy and return it, not later than the time specified in
the Notice of Special Meeting of Exchangeable Shareholders, in the postage-paid
envelope provided.
 
                                          Yours very truly,
 
                                          David B. Robson

     Notice is hereby given that a special meeting of the holders of
exchangeable shares of Veritas Energy Services Inc. ("VESI") will be held at
          (Calgary time) on           ,           , 1999 at           , Calgary,
Alberta, Canada for the following purposes:
 
        1. To consider, pursuant to an order (the "Interim Order") of the Court
           of Queen's Bench of Alberta dated           , 1999 and, if deemed
           advisable, to pass, with or without variation, a special resolution
           (the "Arrangement Resolution") to approve an arrangement (the
           "Arrangement") under section 186 of the Business Corporations Act
           (Alberta) (the "ABCA"), all as more particularly described in the
           accompanying Joint Management Information Circular and Proxy
           Statement (the "Joint Proxy Statement"); and
 
        2. To transact such further or other business as may properly come

set out in the Joint Proxy Statement, which forms part of this notice. The full
text of the Arrangement Resolution is attached as Annex A to the Joint Proxy
Statement.
 
     Pursuant to the Interim Order, a copy of which is attached as Annex C to
the Joint Proxy Statement, holders of VESI Exchangeable Shares have been granted
the right to dissent in respect of the Arrangement. If the Arrangement becomes
effective, a dissenting shareholder will be entitled to be paid the fair value
of the VESI Exchangeable Shares held by such holder if the secretary of VESI or
the chairman of the special meeting shall have received from such dissenting
holder at or before the special meeting a written objection to the Arrangement
Resolution and the dissenting holder shall have otherwise complied with the
provisions of section 184 of the ABCA. The dissent right is described in the
accompanying Joint Proxy Statement and the full text of section 184 of the ABCA
is attached as Annex I to the Joint Proxy Statement. ONLY REGISTERED
SHAREHOLDERS MAY DISSENT. FAILURE TO STRICTLY COMPLY WITH THE REQUIREMENTS SET
OUT IN SECTION 184 OF THE ABCA MAY RESULT IN THE LOSS OF ANY RIGHT TO DISSENT.
 
     David B. Robson, president of VESI and chairman and chief executive officer
of Veritas DGC Inc. and the holder of approximately 86% of the outstanding VESI
Exchangeable Shares entitled to vote, has agreed with Enertec Resource Services
Inc. to vote his VESI Exchangeable Shares in favor of the Arrangement
Resolution. As a result, approval of the Arrangement Resolution by the holders
of VESI Exchangeable Shares is effectively assured.
 
     Each person who is a holder of record of VESI Exchangeable Shares at the
close of business on           , 1999, is entitled to notice of, and to attend
and vote at, the special meeting and any adjournment or postponement thereof,
provided that to the extent a person has transferred any VESI Exchangeable
Shares after the record date and the transferee of such shares establishes that
such transferee owns such shares and demands not later than ten days before the
special meeting to be included in the list of holders eligible to vote at the
special meeting, such transferee will be entitled to vote such shares at the
special meeting. Veritas DGC Inc. may not vote the VESI Exchangeable Shares it
holds at the special meeting. However, the VESI Exchangeable Shares held by
Veritas DGC Inc. will be included in determining if a quorum is present at the
special meeting.
 
     DATED at Calgary, Alberta,           , 1999.

Dear Enertec Shareholder and Enertec Optionholder:
 
     You are cordially invited to attend a special meeting of shareholders and
optionholders of Enertec Resource Services Inc. ("Enertec"), to be held on
          ,           , 1999 at           (Calgary time) at           , Calgary,
Alberta, Canada.
 
     The special meeting is important because we are asking you to approve an
arrangement which will lead to a combination of Enertec, Veritas Energy Services
Inc. ("VESI") and Veritas DGC Inc. ("Veritas DGC").
 
     The details of the proposed transaction are included in the Joint Proxy
Statement. Also included is a form of proxy and a form of letter of transmittal
for Enertec shareholders to enable you to receive Series 1 Exchangeable Shares
of VESI. Please review the Joint Proxy Statement carefully as it has been
prepared to help you make an informed decision.
 
     If the proposed transaction is completed, Enertec shareholders will
transfer each of their Enertec common shares to VESI and the sole consideration
received therefor will be 0.345 (the "Exchange Ratio") of a Series 1
Exchangeable Share of VESI, an Alberta corporation and a subsidiary of Veritas
DGC. Each Series 1 Exchangeable Share is exchangeable for one share of Veritas
DGC common stock. Each Series 1 Exchangeable Share will also entitle its holder
to receive dividends equivalent to any dividends paid on Veritas DGC common
stock and will carry the right to vote at meetings of the stockholders of
Veritas DGC. Holding Series 1 Exchangeable Shares rather than Veritas DGC common
stock may appeal to Enertec shareholders resident in Canada for certain Canadian
tax reasons, which are summarized in the Joint Proxy Statement.
 
     Following the transaction, Enertec will be wholly-owned by VESI, and all of
the former holders of Enertec common shares will hold Series 1 Exchangeable
Shares issued by VESI.
 
     If the proposed transaction is completed, each Enertec option will be
exchanged for an option to purchase a number of whole shares of Veritas DGC
common stock equal to the number of Enertec common shares subject to the Enertec
option multiplied by the Exchange Ratio, rounded down to the nearest whole
number of shares, at an exercise price per share of Veritas DGC common stock
equal to the exercise price per share of such Enertec option divided by the
Exchange Ratio, adjusted into a U.S. dollar equivalent at the time of closing.
The exercise price will be decreased by the amount attributable to any rounding
down of shares.
 
     After considering many different factors which are reviewed in detail in
the Joint Proxy Statement, including, among other things, the opinion of CIBC
Wood Gundy Securities Inc., an investment banking firm engaged by Enertec, that
the consideration to be received by the Enertec shareholders in the transaction
is fair from a financial point of view, your board of directors has unanimously
recommended that you vote in favor of the special resolution concerning the
arrangement and the combination of Veritas DGC, VESI and Enertec.
 
     We hope that you will be able to attend the special meeting. However, if
you are unable to attend the special meeting in person, we urge you to complete
the enclosed form of proxy and return it, not later than the time specified in
the Notice of Special Meeting of Shareholders and Optionholders, in the
postage-paid envelope provided.
 
                                          Yours very truly,

     See, "The Transaction -- Recommendations of Boards of Directors" (page 26).
 
CIBC WOOD GUNDY SECURITIES INC. SAYS TRANSACTION FINANCIALLY FAIR TO ENERTEC
SHAREHOLDERS
 
     CIBC Wood Gundy Securities Inc. has rendered an opinion to the Enertec
board of directors that the consideration to be received by the Enertec
shareholders in the Transaction is fair, from a financial point of view, to the
Enertec shareholders.
 
     See, "The Transaction -- Opinion of CIBC Wood Gundy Securities Inc." (pages
27 through 33) and the full text of the opinion rendered by CIBC Wood Gundy
Securities Inc. set forth in Annex H.
 
                                THE TRANSACTION
 
REASONS FOR THE TRANSACTION
 
     Advantages.  The board of directors of each of Veritas DGC, VESI and
Enertec believe the Transaction will allow the companies to combine their
resources to enhance their ability to compete in certain markets in an evolving
seismic data acquisition and processing services industry. The board of
directors of each of Veritas DGC, VESI and Enertec considered the following
material factors in making their recommendations.
 
     -  From March 1998 to March 1999, the Baker Hughes rotary rig count for
        North America decreased from 942 to 543, a 43% decline. During 1998 and
        early 1999, oil and natural gas prices significantly decreased. These
        factors have caused an oversupply of seismic data acquisition crews and
        seismic processing services and downward pressure on the pricing of
        services. The companies estimate that overall exploration and production
        spending will decline 25% to 30% in 1999 as compared to 1998 and that
        demand for geophysical services onshore North America will decline by a
        greater proportion. The companies believe that market conditions require
        a consolidation of crews, equipment and services to enable them to
        operate more profitably in these markets.
 
     -  The Transaction would allow the companies to integrate their operations,
        allowing the combined company to be more cost effective and therefore
        more competitive in delivering acquisition and processing services. This
        is particularly true in Canada, where management believes that the
        Transaction will result in the combined company being the leading
        seismic contractor.
 
     -  Management of each of the companies believes that consolidation within
        the seismic industry is required as a result of increased capital
        requirements to fund modernization of seismic equipment because of
        rapidly changing technology and increased investment in large data
        library projects.
 
     -  The combined company will gain "critical mass" that will better position
        it to compete with other large seismic companies.
 
     In addition to the joint considerations, the Enertec board considered the
following additional factors:
 
     -  The arrangement of Enertec and VESI is structured to provide Enertec
        shareholders and Enertec optionholders with a security which has a
        significantly larger market capitalization and better liquidity.
 
                                        3
<PAGE>   17
 
     -  The Transaction creates the potential for Enertec, Enertec shareholders
        and Enertec optionholders to benefit through the combined company's
        access to U.S. capital markets, which may lower its cost of capital.
 
     -  The Transaction creates potential for Enertec, Enertec shareholders and
        Enertec optionholders to benefit from the combined company's more
        diverse geophysical product offerings and its established presence in
        selected markets worldwide.
 
     Disadvantages.  The board of directors of each of Veritas DGC, VESI and
Enertec considered the following additional factors:
 
     -  The success of the combined company in the markets in which Enertec
        competes will be partially dependent on the successful integration of
        the companies.
 
     -  The companies have overlapping operations in certain land processing and
        acquisition businesses which will result in integration costs for the
        combined company.
 
TRANSFER OF ENERTEC COMMON SHARES
 
     The arrangement of Enertec and VESI provides that each Enertec Common Share
will be transferred to VESI and the sole consideration received therefor will be
0.345 of a Series 1 Exchangeable Share of VESI.
 
     Holders of such Series 1 Exchangeable Shares will have the right to later
exchange those shares for the same number of shares of Veritas DGC Common Stock.
After all exchanges of Series 1 Exchangeable Shares for Veritas DGC Common
Stock, the former Enertec shareholders will own approximately 2,391,425 shares
of Veritas DGC Common Stock, being approximately 9.5% of the outstanding Veritas
DGC Common Stock. The Series 1 Exchangeable Shares are subject to redemption and
other rights in favor of Veritas DGC and VESI, including the automatic
redemption of the shares which is initially set for the tenth anniversary of the
Transaction. See "The Companies After the Transaction -- VESI Share Capital --
Series 1 Exchangeable Shares of VESI (pages 44 and 45).
 
TREATMENT OF ENERTEC OPTIONS
 
     Each Enertec Option will be exchanged for an option to purchase shares of
Veritas DGC Common Stock. The number of shares of Veritas DGC Common Stock
subject to the option will be determined by multiplying the number of Enertec
Common Shares subject to the option by 0.345 rounded down to the nearest whole
number of shares, at an exercise price per share of Veritas DGC Common Stock
equal to the exercise price per share of the Enertec Option, divided by 0.345,
adjusted into a United States dollar equivalent at the time of closing. The
exercise price will be decreased by the amount attributable to any rounding down
of shares.

ANTICIPATED ACCOUNTING TREATMENT
 
     The Transaction is anticipated to be accounted for using the pooling of
interests method of accounting under U.S. GAAP. See, "The Transaction --
Anticipated Accounting Treatment" (page 39).
 
INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION
 
     The Combination Agreement provides that all rights to indemnification for
Enertec officers and directors will survive the arrangement of Enertec and VESI
and remain in full force in accordance with applicable law, Enertec's and each
of its subsidiaries' charter documents and bylaws, and any agreements with such
directors and officers.
 
     Prior to closing, the coverage provided under Enertec's directors' and
officers' liability insurance will be extended for a period of five years from
the closing date.
 
BUSINESS COMBINATION COSTS
 
     The companies expect to incur non-recurring business combination costs
estimated to be $2.7 million within the 12-month period following the closing.
This estimate includes costs relating to employee severance ($1.5 million) and
integration costs relating to overlapping operations in land processing and
acquisition operations ($300,000). In addition, in connection with the
Transaction, the companies expect to incur aggregate costs for professional fees
of approximately $800,000 and filing fees of approximately $100,000. Using a tax
rate of 36%, the after tax expense of these costs is estimated to be $1.7
million.
 
CERTAIN TAX CONSIDERATIONS
 
     A Canadian tax deferral may be available to certain Enertec shareholders
who receive Series 1 Exchangeable Shares in exchange for their Enertec Common
Shares for so long as they hold Series 1 Exchangeable Shares. Such Enertec
shareholders generally will recognize a capital gain or capital loss for
Canadian federal income tax purposes upon the exchange of their Series 1
Exchangeable Shares for shares of Veritas DGC Common Stock. Where the exchange
is made with VESI (on a redemption or retraction), such shareholders will also
realize a deemed dividend. There are certain conditions and limitations on
qualifying for a Canadian tax deferral including, in some circumstances, filing
a tax election. The forms necessary to make such an election may be obtained
from Revenue Canada. If an Enertec shareholder wishes to file a tax election, a
completed tax election form must be received by VESI no later than 90 days after
closing of the Transaction.
 
     See "Canadian Federal Income Tax Considerations to Enertec Shareholders"
and "United States Federal Income Tax Considerations to Enertec Shareholders"
(pages 51 through 64).
 
DISSENTERS' RIGHTS
 
     Under Delaware law, Veritas DGC stockholders and VESI exchangeable
shareholders will not have appraisal or dissenters' rights related to the
Transaction. Under Alberta law, Enertec shareholders, Enertec optionholders and
VESI exchangeable shareholders will have certain appraisal or dissenters'
rights. See "Dissenting Shareholders' and Optionholders' Rights" (page 108).

DIVIDEND POLICIES
 
     Historically, Veritas DGC and Enertec have not paid dividends on their
capital stock and have no present plans to pay dividends. The payment of any
future dividends on Veritas DGC Common Stock would depend, among other things,
upon the current and retained earnings and financial condition of Veritas DGC,
and upon a determination by its board of directors that the payment of dividends
would be desirable. In addition, the payment of dividends is restricted by the

                                  RISK FACTORS
 
     The following risk factors should be carefully considered before deciding
how to vote your securities. They should be reviewed together with the other
information in this Joint Proxy Statement. Some of these risk factors relate
directly to the Transaction, while others will be present in the combined
company's business independent of the Transaction. If any of the following risks
occur, the business, financial condition or results of operations of the
combined company could be materially harmed. In that case, the trading price of
the combined company's stock could decline.
 
DECREASES IN ENERGY INDUSTRY SPENDING COULD ADVERSELY AFFECT OUR BUSINESS
 
     The seismic business is substantially dependent upon the level of capital
expenditures by oil and gas companies. As a result of the decline in hydrocarbon
commodity prices in 1998 and early 1999, the level of overall oil and gas
industry activity has declined from levels experienced in recent years. If the
capital spending of the combined company's customers decreases in line with
overall recent industry trends, it would likely have a significant adverse
effect upon the demand for the combined company's services and its results of
operations.
 
INTENSE PRICE COMPETITION IN A SLACK MARKET COULD ADVERSELY AFFECT OUR BUSINESS
 
     Competition among seismic contractors historically is and will continue to
be intense. Competitive factors in recent years have included price, crew
experience, equipment availability, technological expertise and reputation for
quality and dependability. Certain competitors operate more data acquisition
crews than the combined company and have substantially greater financial and
other resources. These larger and better financed operators could enjoy an
advantage over the combined company if the competitive environment for contract
awards shifts to one characterized principally by intense price competition.
 
MULTI-CLIENT DATA LIBRARY COULD BECOME IMPAIRED DUE TO WEAK DEMAND OR
TECHNOLOGICAL OBSOLESCENCE
 
     The combined company has invested significant amounts in acquiring and
processing multi-client data, and expects to continue doing so for the
foreseeable future. Although Veritas DGC has typically recovered all the costs
of such surveys, there is no assurance that the combined company will continue
to be able to do so in the future. Technological, regulatory or other industry
or general economic developments could render all or portions of the combined
company's library of multi-client data obsolete or otherwise impair its value.
 
HIGH LEVELS OF FIXED COSTS COULD RESULT IN OPERATING LOSSES
 
     The seismic business is characterized by high fixed costs, and downtime or
low productivity due to reduced demand, weather interruptions, equipment
failures or other causes can result in significant operating losses.
 
FUTURE TECHNOLOGICAL ADVANCES COULD IMPAIR OPERATING ASSETS OR REQUIRE
SUBSTANTIAL UNBUDGETED CAPITAL EXPENDITURES
 
     Seismic data acquisition and processing is a capital intensive business.
The development of seismic data acquisition and processing equipment has been
characterized by rapid technological advancements in recent years, and this
trend is expected to continue. Manufacturers of seismic equipment may develop
new systems that have competitive advantages over systems now in use that could
render the combined company's current equipment obsolete, requiring significant
unplanned capital expenditures to maintain the combined company's competitive
position. Under such circumstances, there can be no assurance that any required
financing would be available on favorable terms.
 
VERITAS DGC SHARE PRICE WILL FLUCTUATE
 
     The market value of the shares that Enertec shareholders receive will
likely differ from the trading price of the Veritas DGC Common Stock prior to
the date of this Joint Proxy Statement. This is because the per share price of
Veritas DGC Common Stock fluctuates as a result of a number of variables,
including its financial performance and general market and economic conditions.
In the Transaction, each Enertec Common Share will
 
                                        8
<PAGE>   22
 
be transferred for 0.345 of a Series 1 Exchangeable Share. This exchange ratio
is fixed. The exchange ratio will not be adjusted in the event of any increase
or decrease in the market price of Enertec Common Shares or Veritas DGC Common
Stock.
 
INTEGRATION OF THE COMBINED COMPANY COULD ADVERSELY IMPACT CERTAIN OPERATIONS
 
     In evaluating the terms of the Transaction, each company analyzed the
other's businesses and made assumptions concerning future operations and
operations of the combined company. One principal assumption was that through
consolidation of operations, the combined company would be in a better
competitive position in certain markets. This may not be achieved unless the
companies are successfully combined in a timely manner.
 
OUR BUSINESS IS SUBJECT TO SEASONAL FLUCTUATIONS
 
     Veritas DGC's and Enertec's seismic operations and quarterly financial
results historically have been subject to seasonal fluctuation. Both companies
attempt to deploy crews and equipment into regions having opposing seasons or
less severe weather conditions, in order to reduce the impact of seasonal
fluctuations.
 
     In addition to seasonality, each company historically has experienced
quarterly fluctuations in operating results. Operating results in any fiscal
quarter may vary as a result of (1) the magnitude of certain contracts for the
acquisition or sale of data, (2) customers' budgetary cycles and (3) with
respect to Veritas DGC, seismic data sales occurring as a result of offshore
lease sales.
 
WE OPERATE UNDER HAZARDOUS CONDITIONS
 
     Seismic data acquisition activities involve operating under extreme weather
and other hazardous conditions. These operations are subject to risks of loss to
property and injury to personnel from such causes as fires and accidental
explosions. Veritas DGC and Enertec carry insurance against these risks in
amounts they consider adequate. The combined company may not, however, be able
to obtain insurance against certain risks or for certain equipment located from
time to time in certain areas of the world.
 
INTERNATIONAL OPERATIONS POSE ADDITIONAL RISKS
 
     In recent years, more of Veritas DGC's revenues have been derived from
international operations and export sales, which are subject to risks of doing
business abroad. These risks include the possibility of unfavorable changes in
tax or other laws. In addition, foreign operations include risks of partial or
total expropriation; currency exchange rate fluctuations and restrictions on
currency repatriation; the disruption of operations from labor and political
disturbances, insurrection or war; and the requirements of partial local
ownership of operations in certain countries. To minimize such risks, each
company generally denominates its international contracts in U.S. dollars and
other currencies it believes to be stable. Each company also obtains insurance
against war, expropriation, confiscation and nationalization when such insurance
is available and when management considers it advisable to do so. This coverage
is not always available and, when available, is subject to cancellation by the
insuring companies on short notice.
 
OUR BUSINESS IS SUBJECT TO GOVERNMENTAL REGULATION
 
     The combined company's operations will be subject to a variety of federal,
provincial, state, foreign and local laws and regulations, including
environmental laws. The combined company will invest financial and managerial
resources to comply with these laws and related permit requirements in its
operations. In recent years, an increased number of data acquisition contracts
have provided for customers to obtain all necessary permits. Customers' failure
to obtain the required permits in a timely manner may result in crew downtime
and operating losses. In the past, Veritas DGC's and Enertec's cost of complying
with governmental regulation has not been material, but the fact that laws or
regulations change frequently makes it impossible to predict the impact on the
combined company's future operations. The adoption of laws and regulations which
have the effect of curtailing exploration by oil and gas companies could
adversely affect the combined company's operations by reducing the demand for
its geophysical services.

     The following tables set forth certain historical per share data of Veritas
DGC and Enertec and combined per share data on an unaudited pro forma basis
after giving effect to the Transaction. This data should be read in conjunction
with "Selected Historical Consolidated Financial Data," "Unaudited Pro Forma
Consolidated Financial Statements" and the separate Consolidated Financial
Statements of Veritas DGC and Enertec and the notes thereto. The unaudited pro
forma consolidated financial data are not necessarily indicative of the
operating results that would have been achieved had the Transaction been in
effect as of the beginning of the periods presented and should not be construed
as representative of future operations.

     results of operations for fiscal years ended July 31, 1996, 1997 and 1998
     have been combined with Enertec's results for fiscal years ended September
     30, 1996, 1997 and 1998. Veritas DGC's results for the six months ended
     January 31, 1998 and 1999 have been combined with Enertec's results for the
     same periods.
 
(2)  Veritas DGC and Enertec expect to incur business combination costs
     estimated to be $2.7 million within the 12-month period following
     consummation of the Transaction. This estimate includes $1.5 million for
     employee severance, $300,000 for integration costs, and $900,000 for
     Transaction costs, consisting of $800,000 for professional fees and
     $100,000 for filing fees. Using a tax rate of 36%, the after tax expense of
     these costs is estimated to be $1.7 million.

                SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA
 
VERITAS DGC (INCLUDING VESI)
 
     The following table sets forth selected historical consolidated financial
data for Veritas DGC for each of the five years in the period ended July 31,
1998 and for the six months ended January 31, 1998 and 1999. Such data for the
five years in the period ended July 31, 1998 has been derived from the audited
Consolidated Financial Statements of Veritas DGC, except that the balance sheet
data as of July 31, 1994 was derived from the unaudited consolidated financial
statements of Veritas DGC. In the opinion of Veritas DGC's management, the
balance sheet data as of July 31, 1994 include all adjustments necessary to
present fairly the financial condition of Veritas DGC at such date. The selected
historical consolidated financial data for the six month periods ended January
31, 1998 and 1999 has been derived from the unaudited consolidated financial
statements of Veritas DGC and include, in the opinion of Veritas DGC's
management, all adjustments necessary to present fairly the results of such
periods. Such data should be read in conjunction with "Veritas DGC Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
     Veritas DGC was formerly named Digicon Inc. ("Digicon"). On August 30,
1996, Digicon and VESI consummated a business combination whereby VESI became a
wholly owned subsidiary of Digicon and Digicon changed its name to Veritas DGC
Inc. As a result of the differing year ends of Digicon and VESI, results of
operations for dissimilar year ends have been combined. Digicon's results of
operations for fiscal years ended July 31, 1994 and 1995 have been combined with
VESI's results of operations for fiscal years ended October 31, 1994 and 1995,
respectively. To conform year ends, Digicon's results of operations for the year
ended July 31, 1996 have been combined with VESI's results of operations for the
twelve months ended July 31, 1996. Accordingly, VESI's operating results for the
period August 1, 1995 through October 31, 1995 are included in the years ended
July 31, 1995 and 1996. An adjustment in an amount equal to the results of
operations for the three-month period is included in the consolidated statements
of changes in stockholders' equity. VESI's revenues, net income, earnings per
share and earnings per share assuming dilution were US$22,150,000, US$936,000,
US$0.05 and US$0.05, respectively, for the period August 1, 1995 through October
31, 1995.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
 
     The following unaudited pro forma consolidated financial statements have
been prepared assuming the Transaction is accounted for as a pooling of
interests. Accordingly, such statements were prepared as if Veritas DGC and
Enertec were combined as of the beginning of the periods presented.
 
     The following unaudited pro forma consolidated balance sheet as of January
31, 1999 and statements of income for the six months ended January 31, 1998 and
1999 are based on the unaudited consolidated financial statements of Veritas DGC
and Enertec and include, in the opinion of Veritas DGC's and Enertec's
management, all adjustments necessary to present fairly the results of such
periods and should be read in conjunction with Veritas DGC's and Enertec's
Management's Discussion and Analysis of Financial Condition and Results of
Operations. The following unaudited pro forma consolidated statements of income
for the three years ended July 31, 1998 have been derived from, and should be
read in conjunction with, the audited Consolidated Financial Statements of
Veritas DGC and Enertec. The financial statements of Veritas DGC for the years
ended July 31, 1997 and 1998 were audited by PricewaterhouseCoopers LLP. The
financial statements of Veritas DGC for the year ended July 31, 1996 were
audited by Deloitte & Touche LLP. The financial statements of Enertec for the
years ended September 30, 1996, 1997 and 1998 were audited by KPMG LLP Chartered
Accountants. The reports of PricewaterhouseCoopers LLP, Deloitte & Touche LLP
and KPMG LLP Chartered Accountants are included with this Joint Proxy Statement.
 
     As a result of the differing year ends of Veritas DGC and Enertec, results
of operations for dissimilar year ends have been combined. Veritas DGC's results
of operations for fiscal years ended July 31, 1996, 1997 and 1998 have been
combined with Enertec's results for fiscal years ended September 30, 1996, 1997,
and 1998. Veritas DGC's results for the six months ended January 31, 1998 and
1999 have been combined with Enertec's results for the same periods. The two
2-month periods of August 1 through September 30, 1997 and 1998 are also
included in Enertec's fiscal years 1997 and 1998. Revenues, net income, net
income per share and net income per share -- assuming dilution were $9,346,000,
$490,000, $0.02 and $0.02 for the period from August 1 through September 30,
1997 and were $5,334,000, $330,000, $0.01 and $0.01 for the period from August 1
through September 30, 1998.
 
     THE UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS ARE PRESENTED FOR
ILLUSTRATIVE PURPOSES ONLY AND ARE NOT NECESSARILY INDICATIVE OF ACTUAL RESULTS
OF OPERATIONS OR FINANCIAL POSITION THAT WOULD HAVE BEEN ACHIEVED HAD THE
TRANSACTION BEEN CONSUMMATED AT THE BEGINNING OF THE EARLIEST PERIOD PRESENTED,
NOR ARE THEY NECESSARILY INDICATIVE OF FUTURE RESULTS.

- ---------------
 
(a)  Enertec reports revenues including amounts billed to customers for
     reimbursable costs. Veritas DGC reports revenues net of such amounts.
 
(b)  Enertec reports fully diluted net income per share in accordance with
     Canadian GAAP which requires, in determining the fully diluted weighted
     average number of shares outstanding, the assumption that all outstanding
     stock options are exercised. In calculating fully diluted earnings per
     share, net income as reported is increased by the imputed earnings, after
     income taxes, on the cash that would have been received on the exercise of
     the options. For U.S. GAAP, in calculating diluted earnings per share, the
     diluted weighted average number of shares outstanding is calculated using
     the treasury method. Under this method, proceeds from the assumed exercise
     of stock options which are in-the-money relative to the average price for
     the period are assumed to be used to purchase outstanding shares at the
     average market price for the period, this purchase reduces the number of
     shares assumed to be issued on the exercise of the options.
 
(c)  Enertec follows the deferral method of accounting for income taxes in
     accordance with Canadian GAAP which relates the provision for income taxes
     to the accounting income for the period. Under the deferral method, the
     amount by which the tax provision differs from the amount of tax currently
     payable is considered to represent the deferral to future periods of
     benefits obtained or expenditures incurred in the current period and
     accordingly is computed at current tax rates. The accumulated tax
     allocation debit or credit is not adjusted to reflect subsequent changes in
     tax rates. In the United States, statement of financial accounting
     standards no. 109, accounting for income taxes (SFAS 109) requires the use
     of the asset and liability method of accounting for income taxes. Under the
     asset and liability method, deferred taxes are recognized for the future
     tax consequences attributable to tax assets and liabilities measured using
     enacted tax rates expected to apply to taxable income in the years in which
     those temporary differences are expected to be recovered or settled. Under
     SFAS 109, the effect on deferred tax assets and liabilities of a change in
     tax rates is included in earnings in the period that includes the enactment
     date.
 
2.   There are no significant adjustments required to the historical
     consolidated financial statements of Enertec or Veritas DGC to conform
     accounting policies of the two companies.

 NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
3.   Enertec's historical consolidated financial statements, which were reported
     in Canadian dollars, have been converted using the Canadian dollar as the
     functional currency for Enertec's operations in Canada and the U.S. dollar
     as the functional currency for Enertec's operations in the U.S. Balance
     sheet items (excluding common stock, contributed surplus and retained
     earnings that have been converted at historical exchange rates) have been
     converted using the exchange rate in effect at the end of Enertec's
     reporting period. Revenue and expense items have been converted at weighted
     average rates in effect during the reporting period. An adjustment has been
     made to stockholders' equity to reflect the translation of Enertec's
     Canadian operations to U.S. dollars and an adjustment has been made to the
     statement of income to reflect the change in the reporting of the U.S.
     operations from Canadian to U.S. dollars.
 
4.   Common stock and additional paid-in capital have been adjusted assuming all
     Series 1 Exchangeable Shares and VESI Exchangeable Shares are exchanged for
     Veritas DGC Common Stock.
 
5.   Veritas DGC and Enertec expect to incur business combination costs
     estimated to be $2.7 million within the 12-month period following
     consummation of the Transaction. This estimate includes $1.5 million for
     employee severance, $300,000 for integration costs, and $900,000 for
     Transaction costs, consisting of $800,000 for professional fees and
     $100,000 for filing fees. The $2.7 million of costs have been tax effected
     using a 36% rate and are estimated to result in an after tax expense of
     approximately $1.7 million.

                                  THE MEETINGS
 
VERITAS DGC
 
     Solicitation and Voting of Proxies.  The accompanying Veritas DGC proxy is
solicited on behalf of the Veritas DGC board for use at the Veritas DGC meeting,
to be held at Veritas DGC's principal executive offices, 3701 Kirby Drive,
Houston, Texas 77098, on           , 1999 at           (Houston time). Only
holders of record of Veritas DGC Common Stock and VESI Exchangeable Shares at
the close of business on           , 1999 will be entitled to vote at the
Veritas DGC meeting. Veritas DGC is not entitled to vote any VESI Exchangeable
Shares which it holds. At the close of business on the Veritas DGC record date,
there were           shares of Veritas DGC Common Stock and           VESI
Exchangeable Shares outstanding and entitled to vote. The shares vote together
as a single class, and each share entitles the holder to one vote on all matters
presented at the Veritas DGC meeting. A majority of the shares, present in
person or by proxy, will constitute a quorum for the transaction of business.
Abstentions and broker non-votes will be considered to be represented for
purposes of a quorum. This Joint Proxy Statement and the accompanying form of
proxy were first mailed to Veritas DGC stockholders and VESI exchangeable
shareholders on or about           , 1999.
 
     Revocability of Proxy.  A stockholder who has given a proxy may revoke it
at any time before it is exercised at the Veritas DGC meeting, by (1) delivering
to the secretary of Veritas DGC (by any means, including facsimile) a written
notice stating that the proxy is revoked, (2) signing and so delivering a proxy
bearing a later date or (3) attending the Veritas DGC meeting and voting in
person (although attendance at the Veritas DGC meeting will not, by itself,
revoke a proxy).
 
     Expenses of Proxy Solicitation.  The expenses of soliciting proxies to be
voted at the Veritas DGC meeting will be paid by Veritas DGC. Following the
original mailing of the proxies and other soliciting materials, Veritas DGC
and/or its agents also may solicit proxies by mail, telephone, facsimile or in
person. Following the original mailing of the proxies and other soliciting
materials, Veritas DGC will request brokers, custodians, nominees and other
record holders of shares to forward copies of the proxy and other soliciting
materials to persons for whom they hold such shares and to request authority for
the exercise of proxies. In such cases, Veritas DGC, upon the request of the
record holders, will reimburse such holders for their reasonable expenses.
 
     Voting Rights.  Stockholders are entitled to one vote for each share held
as of the Veritas DGC record date. Stockholder approval of the amendment (the
"Charter Amendment") to the Veritas DGC Restated Certificate of Incorporation is
required by the Delaware General Corporation Law (the "DGCL"). Such approval
requires the affirmative vote of a majority of the outstanding Veritas DGC
Common Stock and VESI Exchangeable Shares voting as a single class.
 
     Veritas DGC will count abstentions in tabulations of votes cast, and an
abstention, therefore, will have the same effect as a vote against the proposal.
Under Delaware case law, broker non-votes (shares which are present at the
meeting and for which a broker or nominee has received no instruction by the
beneficial owner as to how such owner wishes the shares to be voted) are counted
for purposes of determining whether a quorum is present at the meeting but are
not counted for purposes of determining whether a proposal has been approved.
Thus, a broker non-vote will have the same effect as a negative vote with regard
to the proposal to approve the Charter Amendment.
 
     Auditors.  PricewaterhouseCoopers LLP, certified public accountants, have
served as the independent accountants of Veritas DGC since November 1996.
Representatives of PricewaterhouseCoopers LLP plan to attend the Veritas DGC
meeting and will be available to answer questions. Its representatives will also
have an opportunity to make a statement at the meeting if they so desire,
although it is not expected that any statement will be made.
 
     Stockholder Proposals.  Any stockholder who wishes to submit a proposal for
action to be included in the proxy statement and form of proxy relating to
Veritas DGC's 1999 annual meeting of stockholders is required to submit such
proposal to Veritas DGC on or before July 5, 1999.

VESI
 
     Solicitation and Voting of Proxies.  The accompanying VESI proxy is
solicited on behalf of the VESI board for use at the VESI meeting. The
solicitation of proxies will be primarily by mail but proxies may also be
solicited personally or by telephone by regular employees of VESI or Veritas DGC
without special compensation. The cost of solicitation will be borne by Veritas
DGC. Veritas DGC may also pay brokers or nominees holding VESI Exchangeable
Shares in their names or in the names of their principals for their reasonable
expenses in sending solicitation material to their principals.
 
     Only registered VESI exchangeable shareholders at the close of business on
          , 1999 will be entitled to vote at the VESI meeting, subject to the
provisions of the Business Corporations Act (Alberta) (the "ABCA") regarding
transfers of VESI Exchangeable Shares after the VESI record date. See the
"Notice of Special Meeting of Exchangeable Shareholders" accompanying this Joint
Proxy Statement. Veritas DGC may not vote any VESI Exchangeable Shares held by
it at the VESI meeting. However, such shares will be counted for the purpose of
determining if a quorum is present. At the close of business on the VESI record
date, there were           VESI Exchangeable Shares outstanding.
 
     A quorum of VESI exchangeable shareholders for the transaction of business
at the meeting consists of holders of at least 50% of the VESI Exchangeable
Shares present either in person or by duly appointed proxy.
 
     To be effective, proxies must be received by CIBC Mellon Trust Company not
later than noon (Calgary time) on the day preceding the day of the VESI meeting,

     THE FORM OF PROXY ACCOMPANYING THIS JOINT PROXY STATEMENT CONFERS
DISCRETIONARY AUTHORITY UPON THE PROXY NOMINEES WITH RESPECT TO AMENDMENTS OR
VARIATIONS TO THE MATTERS IDENTIFIED IN THE ACCOMPANYING NOTICE OF THE VESI
MEETING AND OTHER MATTERS WHICH MAY PROPERLY COME BEFORE THE VESI MEETING.
 
     THE SHARES REPRESENTED BY PROXIES AT THE VESI MEETING WILL BE VOTED IN

PROPOSED IN THIS JOINT PROXY STATEMENT.
 
     Management knows of no matters to come before the VESI meeting other than
the matters referred to in the accompanying notice of the VESI meeting. However,
if any other matters which are not now known to management should properly come
before the VESI meeting, the shares represented by proxies in favor of
management nominees will be voted on such matters in accordance with the best
judgment of the proxy nominee.
 
     Revocation of Proxies.  PROXIES GIVEN BY VESI EXCHANGEABLE SHAREHOLDERS FOR
USE AT THE VESI MEETING MAY BE REVOKED AT ANY TIME PRIOR TO THEIR USE. A VESI
exchangeable shareholder giving a proxy may revoke the proxy (1) by instrument

                                THE TRANSACTION
 
BACKGROUND
 
     In August 1996 Digicon Inc., now known as Veritas DGC, completed a
combination with VESI. Digicon's and VESI's seismic operations were
complementary, in that VESI operated primarily onshore in Canada and the
continental United States in its data acquisition operations and Digicon's
principal strength was marine operations in selected markets worldwide. As such,
the combination resulted in each company entering into additional geographic
markets, which lessened the seasonal and cyclical nature of each company's
business, and allowed the combined enterprise to more productively utilize its
assets. Another key component of the combination was achieving "critical mass"
that better positioned the combined company to compete with large competitors
and attract new capital to invest in the industry's rapidly changing technology.
 
     Veritas DGC capitalized on most expected benefits of the combination. From
fiscal year 1996 to fiscal year 1998, combined revenues grew from $250.6 million
to $529 million, an increase of approximately 45% per year during the two year
period. Veritas DGC is now the fifth largest seismic service provider in the
world.
 
     In early January 1999, in light of Veritas DGC's achievements since 1996
and the matters described in "-- Reasons for the Transaction," Murray A. Olson,
chief executive officer of Enertec, contacted David B. Robson, chairman and
chief executive officer of Veritas DGC, with a view to enhancing long-term value
for Enertec shareholders. On January 7, 1999, they met in Houston to determine
whether there was a mutual basis for continuing discussions. During the
remainder of January 1999, the two chief executive officers and other senior
management of each company continued discussions regarding a possible
combination of the companies. On January 26, 1999, the parties entered into a
confidentiality agreement and agreed to exchange information.
 
     During early February 1999, Messrs. Robson and Olson continued negotiations
with respect to an appropriate structure and exchange ratio for the proposed
combination with the assistance of their respective financial, legal and
accounting advisors. On February 15, 1999, Messrs. Robson and Olson reached a
verbal agreement that the transaction should be structured so that Enertec
shareholders would receive Veritas DGC Common Stock or exchangeable shares, and
that the exchange ratio should be effectively 0.345 of a share of Veritas DGC
Common Stock for each Enertec Common Share.
 
     On February 19, 1999, the Enertec board met and approved the exchange
ratio, subject to the conditions specified in a draft letter of intent provided
by Veritas DGC. On February 22, 1999, Veritas DGC and Enertec entered into a
non-binding letter of intent which was conditioned on a number of matters,
including board approvals, due diligence and the execution of a definitive
agreement.
 
     Also on February 22, 1999, the Veritas DGC board met at a special meeting
convened to discuss the proposed transaction. At that meeting, the board
approved management proceeding with a further due diligence review based on the
exchange ratio negotiated. On the same date, a joint press release announcing
the signing of the letter of intent was issued.
 
     On March 9, 1999, the Veritas DGC board unanimously approved the proposed
transaction, subject to conclusion of a definitive agreement, following
presentations as to (1) the results of the operational and legal due diligence
reviews and (2) the projected financial and accounting implications of the
proposed transaction.
 
     On March 22, 1999, the Enertec board received and considered the fairness
opinion of CIBC Wood Gundy Securities Inc. that the exchange ratio is fair to
the Enertec shareholders from a financial point of view. The Enertec board, at
the March 22, 1999 meeting, then unanimously approved the proposed transaction,
subject to conclusion of a definitive agreement, following presentations as to
(1) the results of the operational and legal due diligence review and (2) the
projected financial and accounting implications of the proposed transaction.
 
     Subsequent to the board meetings, negotiation of the combination agreement
among Veritas DGC, VESI and Enertec (the "Combination Agreement") continued and
culminated with the execution of the Combination Agreement effective March 30,

REASONS FOR THE TRANSACTION
 
     Advantages.  The board of directors of each of Veritas DGC, VESI and
Enertec believe the Transaction will allow the companies to combine their
resources to enhance their ability to compete in certain markets in an evolving
seismic data acquisition and processing services industry. The board of
directors of each of Veritas DGC, VESI and Enertec considered the following
material factors in making these recommendations:
 
     -  From March 1998 to March 1999, the Baker Hughes rotary rig count for
        North America decreased from 942 to 543, a 43% decline. During 1998 and
        early 1999, oil and natural gas prices significantly decreased. These
        factors have caused an oversupply of seismic data acquisition crews and
        seismic processing services and downward pressure on the pricing of
        services. The companies estimate that overall exploration and production
        spending will decline 25% to 30% in 1999 as compared to 1998 and that
        demand for geophysical services onshore North America will decline by a
        greater proportion. The companies believe that market conditions require
        a consolidation of crews, equipment and services to enable them to
        operate more profitably in these markets.
 
     -  The Transaction would allow the companies to integrate their operations,
        allowing the combined company to be more cost effective and therefore
        more competitive in delivering acquisition and processing services. This
        is particularly true in Canada, where management of each of the
        companies believes that the Transaction will result in the combined
        company being the leading seismic contractor.
 
     -  Management of each of the companies believes that consolidation within
        the seismic industry is required as a result of increased capital
        requirements to fund modernization of seismic equipment because of
        rapidly changing technology and increased investment in large data
        library projects.
 
     -  The combined company will gain "critical mass" that will better position
        it to compete with other large seismic companies.
 
     In addition to the joint considerations, the Enertec board considered the
following additional factors:
 
     -  The arrangement of Enertec and VESI is structured to provide Enertec
        shareholders and Enertec optionholders with a security which has a
        significantly larger market capitalization and better liquidity.
 
     -  The Transaction creates the potential for Enertec and Enertec
        shareholders and Enertec optionholders to benefit through the combined
        company's access to U.S. capital markets, which may lower its cost of
        capital.
 
     -  The Transaction creates the potential for Enertec and Enertec
        shareholders and Enertec optionholders to benefit from the combined
        company's more diverse geophysical product offerings and its established
        presence in selected markets worldwide.
 
     Disadvantages.  The board of directors of each of Veritas DGC, VESI and
Enertec considered the following additional factors:
 
     -  The success of the combined company in markets in which Enertec competes
        will be partially dependent on the successful integration of the
        companies.
 
     -  The companies have overlapping operations in certain land processing and
        acquisition businesses which will result in integration costs for the
        combined company.
 
RECOMMENDATIONS OF BOARDS OF DIRECTORS
 
     Veritas DGC.  The Veritas DGC board of directors unanimously recommends
that the Veritas DGC stockholders and VESI exchangeable shareholders vote to
approve the Charter Amendment.
 
     VESI.  The VESI board of directors believes that the Transaction is in the
best interests of the VESI exchangeable shareholders. It unanimously recommends
that the VESI exchangeable shareholders vote to approve the Arrangement.
 
                                       26
<PAGE>   40
 
     Enertec.  The Enertec board of directors believes that the Transaction is
in the best interests of the Enertec shareholders and Enertec optionholders. It
unanimously recommends that the Enertec shareholders and Enertec optionholders
vote to approve the Arrangement.
 
     In reaching the conclusions stated above, the boards of directors of
Veritas DGC, VESI and Enertec considered a number of factors including certain
advantages and disadvantages of proceeding with the Transaction. For a
discussion of these considerations, see, "-- Reasons for the Transaction."
 
BUSINESS COMBINATION COSTS
 
     The companies expect to incur non-recurring business combination costs
estimated to be $2.7 million within the 12-month period following the closing.
This estimate includes costs relating to employee severance ($1.5 million) and
integration costs relating to overlapping operations in land processing and
acquisition operations ($300,000). In addition, in connection with the
Transaction the companies expect to incur aggregate costs for professional fees
of approximately $800,000 and filing fees of approximately $100,000. Using a tax
rate of 36%, the after tax expense of these costs is expected to be $1.7
million.
 
OPINION OF CIBC WOOD GUNDY SECURITIES INC.
 
     THE FULL TEXT OF THE OPINION OF CIBC WOOD GUNDY SECURITIES INC. ("CIBC WOOD
GUNDY") DATED MARCH 30, 1999 (THE "OPINION") IS ATTACHED AS ANNEX H TO THIS
JOINT PROXY STATEMENT AND IS INCORPORATED HEREIN BY REFERENCE. ENERTEC
SHAREHOLDERS ARE URGED TO READ THE OPINION CAREFULLY AND IN ITS ENTIRETY FOR A
DESCRIPTION OF THE PROCEDURES FOLLOWED, THE FACTORS CONSIDERED, THE ASSUMPTIONS
AND QUALIFICATIONS MADE BY CIBC WOOD GUNDY IN RENDERING THE OPINION AND OTHER
FACTORS RELATING TO CIBC WOOD GUNDY'S ENGAGEMENT BY ENERTEC. THE SUMMARY OF THE
OPINION SET FORTH IN THIS JOINT PROXY STATEMENT IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE FULL TEXT OF THE OPINION.
 
     Enertec retained CIBC Wood Gundy as its exclusive financial advisor in
connection with the Transaction. In connection with this engagement, Enertec
requested CIBC Wood Gundy to render an opinion as to whether or not the
consideration to be received by the Enertec shareholders in the Transaction (the
"Transaction Consideration") was fair, from a financial point of view, to the
Enertec shareholders.
 
     CIBC Wood Gundy delivered the Opinion as of March 30, 1999 to the Enertec
board to the effect that, as of the date of the Opinion, and subject to certain
assumptions, factors and limitations set forth in the Opinion, the Transaction
Consideration was fair, from a financial point of view, to the Enertec
shareholders.
 
     The Opinion was prepared at the request of and for the use and benefit of
the Enertec board in connection with its consideration of the Transaction and
relates only to the fairness, from a financial point of view, of the Transaction
Consideration to the Enertec shareholders. The Opinion does not address any
other aspect of the Transaction or related transactions, nor does it address the
relative merits of the Transaction and any other transactions or business
strategies discussed by the Enertec board as alternatives to the Transaction, or
the decision of the Enertec board to proceed with the Transaction. The Opinion
does not constitute a recommendation to any shareholder of Enertec as to how
such shareholder should vote on the approval of the Transaction. The Opinion was
only one of many factors considered by the Enertec board in its evaluation of
the Transaction Consideration and the Transaction and should not be viewed as
determinative of the views of the Enertec board or management with respect to
the Transaction Consideration or the Transaction. CIBC Wood Gundy was not
requested to and did not make any recommendation to the Enertec board as to the
form or amount of the Transaction Consideration to Enertec shareholders
reflected in the Arrangement and the Combination Agreement, which was determined
through arm's-length negotiations between Enertec and Veritas DGC. In arriving
at its opinion, CIBC Wood Gundy did not ascribe a specific range of values to
Enertec, but made its determination as to the fairness, from a financial point
of view, to the Enertec shareholders of the Transaction Consideration on the
basis of financial and comparative analyses summarized below.

        Veritas DGC, relating to the respective business, earnings, cash flow,
        assets and prospects of Enertec and Veritas DGC, furnished to it by
        Enertec and Veritas DGC, respectively;
 
     -  discussions with members of senior management of Enertec and Veritas DGC
        concerning their respective businesses and prospects;
 
     -  historical market prices and trading activity for the Enertec Common

        and those of certain publicly traded companies which it deemed to be
        relevant;
 
     -  the financial terms of the Arrangement and the financial terms of
        certain other business combinations which it deemed to be relevant;
 
     -  the merger premiums paid in recent mergers and acquisitions of public
        companies deemed relevant;
 
     -  potential pro forma financial effects of the Arrangement on Enertec and
        Veritas DGC;
 
     -  discussions with legal counsel to Enertec with respect to various
        matters;

        Enertec and Veritas DGC and addressed to it, dated March 30, 1999 in the
        case of Enertec and dated March 22, 1999 in the case of Veritas DGC; and
 
     -  such other information, investigations and analyses as it considered
        appropriate in the circumstances.
 
     In rendering the Opinion, CIBC Wood Gundy relied upon and assumed the
completeness, accuracy and fair representation of all financial and other
information, data, advice, opinions and representations obtained by it from
public sources or provided to it by Enertec, Veritas DGC and their affiliates or
advisors or otherwise pursuant to its engagement and the Opinion was conditioned
upon such completeness, accuracy and fair representation. Subject to the
exercise of professional judgment and except as expressly described herein, CIBC
Wood Gundy did not attempt to verify independently the accuracy or completeness
of any such information, data, advice, opinions and representations. Senior
management of Enertec and Veritas DGC represented to CIBC Wood Gundy, in letters
delivered as of March 30, 1999 in the case of Enertec and as of March 22, 1999,
in the case of Veritas DGC, among other things, that the information, data,
opinions and other materials provided to it by or on behalf of Enertec or
Veritas DGC were complete and correct as of the date of such information and
that since the date of such information, there had been no material change,
financial or otherwise, in the position of Enertec or Veritas DGC, or in their
assets, liabilities (contingent or otherwise), businesses or operations and
there had been no changes of any material fact of a nature as to render the
information untrue or misleading in any material aspect.

     The preparation of a fairness opinion involves various determinations as to
the most appropriate and relevant quantitative methods of financial analyses and
the application of those methods to the particular circumstances and, therefore,
such an opinion is not readily susceptible to partial analysis or summary
description. Accordingly, CIBC Wood Gundy believes that its analysis must be
considered as a whole and that considering any portion of such analysis and of
the factors considered, without considering all analyses and factors, could
create a misleading or incomplete view of the process underlying the Opinion.
The Opinion was rendered on the basis of securities markets, economic and
general business and financial conditions prevailing as of its date and the
condition and prospects, financial and otherwise, of Enertec and Veritas DGC as
they were reflected in the information and documents reviewed by CIBC Wood Gundy
and as they were represented to CIBC Wood Gundy in its discussions with the
respective management of each of Enertec and Veritas DGC. In its analyses and in
connection with its preparation of the Opinion, CIBC Wood Gundy made numerous
assumptions with respect to industry performance, general business, market and
economic conditions and other matters, many of which are beyond the control of
CIBC Wood Gundy or any party involved in the Arrangement. Any estimates
contained in these analyses are not necessarily indicative of actual values or
predictive of future results or values, which may be significantly more or less
favorable than as set forth therein. In addition, analyses relating to the value
of businesses do not purport to be appraisals or to reflect the prices at which
businesses may actually be sold. CIBC Wood Gundy was not authorized by Enertec
or its board of directors to solicit, nor did it solicit, third party
indications of interest for the acquisition or merger of Enertec.
 
     Some of the summaries of financial analyses include information presented
in tabular format. In order to fully understand the financial analyses performed
by CIBC Wood Gundy, the tables must be read together with the text of each
summary. The tables alone do not constitute a complete description of the
financial analyses. Considering the data set forth in the tables without
considering the full narrative description of the financial analyses, including
the methodologies and assumptions underlying the analyses, could create a
misleading or incomplete view of the financial analyses performed by CIBC Wood
Gundy. The following paragraphs summarize the significant analyses performed by
CIBC Wood Gundy in arriving at the Opinion.
 
     Share Trading History.  To provide contextual data and comparative market
data, CIBC Wood Gundy reviewed the history of the trading prices and volume for
the Enertec Common Shares and the Veritas DGC Common Stock, both separately and
in relation to a market index and two comparative company indices. The market
index used was the Standard & Poor's 500 Index. The comparative company indices
used were an index of twelve seismic services companies and an index of five
Canadian-based oilfield services companies. In addition, CIBC Wood Gundy
reviewed the historical relative relationship between the per share market
prices of the Enertec Common Shares and the Veritas DGC Common Stock and
compared this to the Transaction Consideration. CIBC Wood Gundy further noted
that the relationship of the Veritas DGC Common Stock to the Enertec Common
Shares at all times during the two periods presented below was never higher than
the Transaction Consideration.

     Selected Comparative Public Company Analysis.  Using publicly available
information, CIBC Wood Gundy compared selected historical and projected
financial, operating and stock market performance data of Enertec and Veritas
DGC to the corresponding data of publicly traded seismic services companies that
included the following:
 
     -  Cie Generale de Geophysique
 
     -  Core Laboratories N.V.
 
     -  Dawson Geophysical Company
 
     -  Eagle Geophysical, Inc.
 
     -  GeoKinetics Inc.
 
                                       29
<PAGE>   43
 
     -  Input/Output Inc.
 
     -  Kelman Technologies Inc.
 
     -  Omni Energy Services Corp.
 
     -  Paradigm Geophysical Ltd.
 
     -  Petroleum Geo-Services, AS
 
     -  Seitel, Inc.
 
     -  TGS Nopec ASA
 
     With respect to these companies, CIBC Wood Gundy noted that:
 
     -  all but one were listed on U.S. stock exchanges, unlike Enertec, and had
        generally larger market values and greater trading liquidity than
        Enertec; and
 
     -  the companies with U.S. listings, with generally larger market values
        and with greater trading liquidity have generally traded at premium
        multiples to those of Enertec.
 
     Both Enertec and Veritas DGC operate businesses for which there are no
directly comparable companies. Accordingly, analysis of the results of the
foregoing was not simply mathematical nor necessarily precise; rather, it
involved complex consideration and judgments concerning differences in financial
and operating characteristics of companies and other factors that could affect
public trading values. Nonetheless, CIBC Woody Gundy believed the following six
seismic companies to be the most comparable to Enertec due to the greater
similarities of their business operations.
 
     -  Dawson Geophysical Company
 
     -  Eagle Geophysical, Inc.
 
     -  Paradigm Geophysical Ltd.
 
     -  Cie Generale de Geophysique
 
     -  Kelman Technologies Inc.
 
     -  GeoKinetics Inc.
 
     In its analysis, CIBC Wood Gundy believed the multiples of 1998 and
estimated 1999 earnings before interest, taxes, depreciation and amortization
("EBITDA") and after-tax cash flow from operations ("CFFO"), which are widely
accepted measures of cash flow, and the most recent book values of assets and
shareholders' equity to be the most relevant for the comparative company trading
analysis. CIBC Wood Gundy determined the average multiples of these six selected
companies, which are presented below. Estimated 1999 net income, CFFO and EBITDA
were estimated by independent research analysts and compiled by CIBC Wood Gundy.
 
<TABLE>
<S>                                                           <C>

- -- 1999 CFFO................................................   6.6X
- -- Shareholders' Equity.....................................   0.8X
</TABLE>
 
     CIBC Wood Gundy noted that prior to the announcement of the letter of
intent with respect to the Transaction, the indicated trading multiples of
Enertec were below the indicated range of average trading
 
                                       30
<PAGE>   44
 
multiples of the six comparative companies and that after the close of trading
on February 22, 1999, the date of the transaction announcement, and on March 30,
1999, the date of the Opinion, the indicated trading multiples of Enertec
generally fell within or at a premium to the average trading multiples of these.
 
     By applying the corresponding multiples presented above to Enertec's 1998
EBITDA, net income and CFFO and estimated 1999 EBITDA, Net Income and CFFO and
book value of assets and shareholders' equity, CIBC Wood Gundy arrived at a
range of estimated fully-diluted equity values of C$2.67 to C$8.24 per share.
 
     Selected Comparative Transaction Analysis.  CIBC Wood Gundy reviewed
publicly available financial information for the following four mergers and
acquisitions involving oilfield services companies that CIBC Wood Gundy believed
to be reasonably comparable to the Transaction:
 
     -  Key Energy Services, Inc./Dawson Production Services, Inc.
 
     -  R&B Falcon Corp./Cliffs Drilling Co.
 
     -  Nabors Industries Inc./Bayard Drilling Technologies Inc.
 
     -  Nabors Industries Inc./Pool Energy Services Co.
 
     CIBC Wood Gundy noted that there are no directly comparable transactions to
the Transaction.
 
     For the comparative transactions, CIBC Wood Gundy calculated the following
average multiples for the acquisitions above:
 
<TABLE>
<S>                                                           <C>
Equity Purchase Price to:
- -- Last twelve months EBITDA................................   7.7X
- -- Forward Consensus EBITDA.................................   5.8X
- -- Book Value of Assets.....................................   1.0X
 
Aggregate Purchase Price to:
- -- Last twelve months Net Income............................  21.5X
- -- Last twelve months CFFO..................................   6.2X
- -- Forward Consensus Net income.............................  21.6X
- -- Forward Consensus CFFO...................................   5.3X
- -- Shareholders' Equity.....................................   1.2X
</TABLE>
 
     By applying the corresponding multiples of the comparative transactions
presented above to Enertec's 1998 Net Income, CFFO and EBITDA and estimated 1999
Net Income, CFFO and EBITDA and book value of its assets and shareholders'
equity, CIBC Wood Gundy arrived at a range of estimated fully-diluted equity
values of C$3.95 to C$13.40 per share.
 
     Pro Forma Combination Analysis. CIBC Wood Gundy performed an analysis of
the potential pro forma effect of the Transaction on Enertec's per share
earnings and CFFO for the years ending December 31, 1998 and December 31, 1999,
which assumed that the Transaction was consummated on December 31, 1997. In
performing this analysis, CIBC Wood Gundy assumed:
 
     -  the Transaction will provide 0.345 of a Series 1 Exchangeable Share in
        exchange for each Enertec Common Share;
 
     -  the Transaction would be accounted for under the pooling-of-interests
        method of accounting;
 
     -  Enertec shareholders resident in Canada would generally receive tax
        deferred treatment on the receipt of Series 1 Exchangeable Shares; and
 
     -  annual operating cost savings of approximately $1.5 million, which were
        estimated by Veritas DGC, could be achieved as a result of the
        Transaction.
 
     CIBC Wood Gundy combined the historical and projected operating results of
Enertec (provided by Enertec management) with the corresponding historical and
projected operating results of Veritas DGC (provided by Veritas DGC management)
to arrive at the combined company pro forma historical and projected operating
 
                                       31
<PAGE>   45
 
results. CIBC Wood Gundy divided these results by the pro forma fully diluted
shares outstanding to arrive at a combined company per share earnings and CFFO.
CIBC Wood Gundy then compared the combined company per share earnings and CFFO
to Enertec's historical and projected stand-alone per share earnings and CFFO
(provided by Enertec management) to determine the pro forma impact of the
Transaction. This analysis suggested that, on a pro forma basis assuming the
Transaction was consummated on December 31, 1997:
 
     -  the Transaction would have been accretive to Enertec's per share
        earnings and CFFO in 1998; and
 
     -  assuming the accuracy of the projected results supplied by the
        respective companies, the Transaction would be accretive to Enertec's
        per share earnings and CFFO in 1999.
 
     Merger Premium Analysis.  CIBC Wood Gundy examined median percentage
premiums of the purchase price paid at announcement date for the following
comparative transactions:
 
     -  Baker Hughes Incorporated/Western Atlas Inc.
 
     -  Key Energy Services, Inc./Dawson Production Services, Inc.
 
     -  R&B Falcon Corp./Cliffs Drilling Co.
 
     -  Nabors Industries Inc./Bayard Drilling Technologies Inc.
 
     -  Nabors Industries Inc./Pool Energy Services Co.
 
     CIBC Wood Gundy determined the median percentage premium paid in the above
comparative transactions, being the value of the consideration as of the date of
announcement of the comparative transaction, relative to the target's share
price for the period specified in the table below. These medians were compared
to the premium paid to Enertec shareholders in respect of the Veritas DGC Common
Stock price, as of the close of trading on February 22, 1999, relative to
Enertec's share price for the periods specified in the table below.

     CIBC Wood Gundy also determined the median percentage premium paid in the
above comparative transactions, being the value of the consideration as of the
date of the comparative transaction, or if not closed, as of March 30, 1999,
relative to the acquiror's share price for the periods specified in the table
below. These medians were compared to the premium paid to Enertec shareholders
in respect of the Veritas DGC Common Stock prices as of March 30, 1999, relative
to Enertec's share prices for the periods specified in the table below.

     Pursuant to an engagement agreement dated February 26, 1999, among Enertec,
CIBC Wood Gundy and CIBC Oppenheimer Corp., Enertec has agreed to pay CIBC Wood
Gundy: (1) a fee of C$100,000 in connection with CIBC Wood Gundy's delivery of
an opinion to the Enertec board regarding the fairness, from a financial point
of view, of the Transaction Consideration, and (2) a fee of C$65,000 for Dealer
Manager services, if these services are requested by Enertec's board. Enertec
has also agreed to reimburse CIBC Wood Gundy for its reasonable out-of-pocket
fees, expenses and costs, including reasonable fees and disbursements of its
legal counsel. In addition, Enertec has agreed to indemnify CIBC Wood Gundy,
CIBC Oppenheimer Corp., their affiliates and their respective directors,
officers, employees and advisors, against certain liabilities, including
liabilities under relevant securities laws.
 
     CIBC Wood Gundy was selected by the Enertec board based on CIBC Wood
Gundy's substantial experience in transactions similar to the Transaction and
familiarity with Enertec and its operations and the oilfield services industry
generally. CIBC Wood Gundy regularly engages in the valuation of businesses and
their securities in
 
                                       32
<PAGE>   46
 
connection with mergers and acquisitions, negotiated underwritings, competitive
bids, secondary distributions of listed and unlisted securities, private
placements and valuations for corporate and other purposes.
 
     In the ordinary course of its business, CIBC Wood Gundy and its affiliates
may actively trade the securities of Enertec for its own account and for the
accounts of its customers and, accordingly, may at any time hold a long or short
position in such securities.
 
TRANSACTION MECHANICS
 
     The following is a summary description of the Arrangement and is qualified
in its entirety by the full text of the Arrangement attached as Annex D.
 
     The following diagrams set forth the ownership structure of the parties to
the Arrangement before and after the Transaction.
                       [DIAGRAMS OF OWNERSHIP STRUCTURE]
 
     The Arrangement provides that each Enertec Common Share will be transferred
by the Enertec shareholders to VESI and the sole consideration received therefor
will be for 0.345 (the "Exchange Ratio") of a VESI Series 1 Exchangeable Share.
Holders of Series 1 Exchangeable Shares will have the right to later exchange
those shares for the same number of shares of Veritas DGC Common Stock. After
all exchanges of Series 1 Exchangeable Shares for Veritas DGC Common Stock, the
former Enertec shareholders will own approximately 2,391,425 shares of Veritas
DGC Common Stock, being approximately 9.5% of the outstanding Veritas DGC Common
Stock. On the 10th anniversary of the Effective Date, unless such date shall be
extended to a specified later date
 
                                       33
<PAGE>   47
 
by the VESI board of directors, not to be later than the 15th anniversary of the
Effective Date, or such earlier date as specified by the VESI board of directors
if:
 
     -  there are fewer than 10,000 Series 1 Exchangeable Shares outstanding
        (other than Series 1 Exchangeable Shares held by Veritas DGC and
        entities controlled by Veritas DGC); or
 
     -  if at any time after the 5th anniversary there are fewer than 250,000
        VESI Exchangeable Shares outstanding (other than VESI Exchangeable
        Shares held by Veritas DGC and entities controlled by Veritas DGC) and
        Veritas DGC exercises its option to redeem all of such outstanding VESI
        Exchangeable Shares,
 
(the "Automatic Redemption Date"), VESI must redeem all but not less than all of
the then outstanding Series 1 Exchangeable Shares in exchange for an equal
number of shares of Veritas DGC Common Stock, plus an additional amount
equivalent to the full amount of all declared and unpaid dividends on such
Series 1 Exchangeable Shares. However, Veritas DGC will have the overriding
right to purchase on the Automatic Redemption Date all but not less than all of
the outstanding Series 1 Exchangeable Shares in exchange for one share of
Veritas DGC Common Stock for each such Series 1 Exchangeable Share, plus an
additional amount equivalent to the full amount of all declared and unpaid
dividends on such Series 1 Exchangeable Share. VESI shall, at least 120 days
before the Automatic Redemption Date, provide the registered holders of Series 1
Exchangeable Shares with written notice of the proposed redemption of the Series
1 Exchangeable Shares by VESI.
 
     Veritas DGC and VESI will enter into agreements to ensure that holders of
the Series 1 Exchangeable Shares will have the same voting, dividend and
liquidation rights as holders of Veritas DGC Common Stock.
 
     The Series 1 Exchangeable Shares are subject to adjustment or modification
in the event of a stock split or other changes to the capital structure of
Veritas DGC so as to maintain the initial one-to-one ratio between the Series 1
Exchangeable Shares and Veritas DGC Common Stock.
 
     Enertec shareholders will be entitled to make an income tax election
pursuant to section 85 of the Income Tax Act (Canada) (the "Canadian Tax Act")
with respect to the transfer of their Enertec Common Shares to VESI by providing
two signed copies of the necessary election forms to VESI within 90 days
following the effective date of the Transaction (the "Effective Date"), duly
completed with the details of the number of shares transferred and the
applicable agreed amounts for the purposes of such elections. Thereafter,
subject to the election forms complying with the provisions of the Canadian Tax
Act, the forms will be signed by VESI and returned to such Enertec shareholders
for filing with Revenue Canada.
 
     The sole consideration to be received by the holders of Enertec Common
Shares for the transfer of such shares to VESI shall be the Series 1
Exchangeable Shares issued in connection with such transfer. All other rights
and benefits received by the holders of Enertec Common Shares in connection with
the consummation of the Arrangement shall be in consideration of the grant by
such holders to Veritas DGC of Veritas DGC's rights in respect of the Series 1
Exchangeable Shares and the other consideration received by Veritas DGC from the
holders of Enertec Common Shares (excluding the Enertec Common Shares)
including, without limitation, the termination of the Rights (as defined in the
Shareholder Rights Plan Agreement between Enertec and Montreal Trust Company of
Canada) (the "Veritas DGC Consideration").
 
     At the effective time of closing of the Transaction (the "Effective Time"),
each Enertec Option outstanding immediately prior to the Effective Time will be
exchanged for an option under the Veritas DGC Option Plan exercisable for a
number of whole shares of Veritas DGC Common Stock equal to the number of
Enertec Common Shares subject to the Enertec Option at the Effective Time
multiplied by the Exchange Ratio, at an exercise price per share of Veritas DGC
Common Stock equal to the exercise price per share of such Enertec Option
immediately prior to the Effective Time divided by the Exchange Ratio, such
exercise price to be converted into United States dollars. If this calculation
results in an exchanged Enertec Option being exercised for a fractional share of
Veritas DGC Common Stock, then the number of shares shall be rounded down to the
nearest whole number of shares and the total exercise price for the option will
be reduced by the exercise price of the fractional share. Each Veritas DGC
Option shall be fully vested immediately after the Effective Time.
 
                                       34
<PAGE>   48
 
     In order to facilitate the completion of the combination, the Arrangement
will also include the following:
 
     -  the elimination of the unissued Class 1 Preferred Shares of Enertec,
 
     -  the amendment of all share provisions and contractual terms in
        connection with the VESI Exchangeable Shares which restrict the ability
        of VESI to issue further exchangeable shares,
 
     -  the amendment of all share provisions and contractual terms necessary to
        allow for all VESI exchangeable shares issued now and in the future to
        rank equally so that no future exchangeable share issuances will
        prejudice former groups of exchangeable shareholders,
 
     -  the creation of a new class of VESI exchangeable shares issuable in
        series, the first such series being the Series 1 Exchangeable Shares
        used to complete the Transaction, and
 
     -  the termination of the Shareholder Rights Plan Agreement between Enertec
        and Montreal Trust Company of Canada and all outstanding rights under
        the agreement.
 
     In order to allow Veritas DGC to consolidate its Canadian operations, the
Transaction structure will result in Enertec becoming a wholly-owned subsidiary
of VESI. Under the ABCA, a wholly-owned subsidiary may be consolidated with its
parent by way of either amalgamation or wind-up through a procedure requiring
only directors' approval. Following the Effective Date, Veritas DGC will review
Enertec's operations in order to identify the benefits which may result from a
consolidation.
 
     In order to complete any future desired business combinations involving the
issuance of additional exchangeable shares without the necessity of incurring
the time and expense of obtaining the consent of exchangeable shareholders from
prior transactions, the Arrangement will also permit VESI to issue further
series of the Class A Exchangeable Shares (of which the Series 1 Exchangeable
Shares are a series) by action of its board of directors. The articles of VESI
and related contractual agreements will provide that all VESI exchangeable
shares will rank equally so that future issuances will not prejudice former
groups of exchangeable shareholders.
 
     Finally, the Arrangement includes two matters which are unrelated to the
Transaction or future combination transactions. The first would increase the
number of authorized shares of VESI from one to an unlimited number in order to
provide flexibility for intercorporate transactions between VESI and Veritas
DGC. Veritas DGC would still be required to own all issued VESI common shares.
The second matter would provide for meetings of VESI shareholders to be held in
Houston, Texas, as well as in Alberta.
 
     Enclosed with copies of this Joint Proxy Statement delivered to the
registered holders of Enertec Common Shares is the Enertec letter of
transmittal, which when duly completed and returned together with a certificate
for Enertec Common Shares, will enable the holder to receive the number of
Series 1 Exchangeable Shares to which such holder is entitled. See "--
Procedures for Transfer of Share Certificates by Enertec Shareholders and
Enertec Optionholders."
 
     On the Effective Date, Veritas DGC's Restated Certificate of Incorporation
will be amended to (1) create a new series of ordinary shares, designated ERS
Special Voting Stock, and (2) delete a restriction which prohibits the Veritas
DGC board of directors from designating a new series of ordinary shares, such as
the ERS Special Voting Stock, without the approval of all outstanding ordinary
shares. See, "Proposed Veritas DGC Charter Amendment."
 
THE COMBINATION AGREEMENT
 
     Representations, Warranties and Covenants.  The Combination Agreement among
Veritas DGC, VESI and Enertec dated as of March 30, 1999, attached as Annex B
(the "Combination Agreement"), contains certain customary representations and
warranties of each of Enertec and Veritas DGC relating to, among other things,
their respective organization, capital structures, qualification, operations,
financial condition, intellectual property rights, year 2000 compliance,
compliance with necessary regulatory or governmental authorities and other
matters, including their authority to enter into the Combination Agreement and
to consummate the Transaction. The Combination Agreement also contains
representations of VESI relating to, among other things, its capital
 
                                       35
<PAGE>   49
 
structure, tax status, compliance with necessary regulatory or governmental
authorities and other matters, including its authority to enter into the
Combination Agreement and to consummate the Transaction. Pursuant to the
Combination Agreement, the parties have agreed to advise each other of material
changes and to provide the others with interim financial information. Further,
the parties have agreed to apply for and use their commercially reasonable
efforts to obtain all court, regulatory and other consents and approvals
required for the consummation of the Combination Agreement, to use their
commercially reasonable efforts to effect the transactions contemplated by the
Combination Agreement, including the preparation and mailing of this Joint Proxy
Statement, and to provide the other parties and their respective counsel with
such information as they may reasonably request. Also pursuant to the
Combination Agreement, Veritas DGC and Enertec have covenanted that, among other
things, until the earlier of the termination of the Combination Agreement or the
Effective Time, each will maintain its business, not take certain actions
outside the ordinary course, and use its commercially reasonable efforts to
consummate the Transaction. Veritas DGC also agreed to use its commercially
reasonable efforts, with the cooperation and assistance of Enertec, to list the
Series 1 Exchangeable Shares on the TSE as of the Effective Date.
 
     The Combination Agreement also provides that until the earlier of the
Effective Time or the termination of the Combination Agreement, Enertec and its
subsidiaries will not (and it will use its best efforts to ensure that none of
its officers, directors, employees, agents, representatives or affiliates)
directly or indirectly:
 
     -  solicit, encourage, initiate or participate in any negotiations,
        inquiries or discussions with respect to any offer or proposal (an
        "Acquisition Proposal") to acquire all or any significant part of its
        business, assets or capital shares whether by arrangement, amalgamation,
        merger, consolidation, other business combination, purchase of assets,
        tender or exchange offer or otherwise (each of the foregoing, an
        "Acquisition Transaction");
 
     -  disclose any information not customarily disclosed to any person
        concerning its business or properties or afford to any person or entity
        access to its properties, books or records, except in the ordinary
        course of business and as required by law or pursuant to a governmental
        request for information;
 
     -  enter into or execute any agreement relating to an Acquisition
        Transaction, plan of reorganization, or other agreement calling for the
        sale of all or any significant part of its business and properties; or
 
     -  except as required by law, make or authorize any public statement,
        recommendation or solicitation with respect to any Acquisition
        Transaction or any offer or proposal relating to an Acquisition
        Transaction other than with respect to the Arrangement,
 
provided that the Combination Agreement does not prevent the Enertec board from
considering, negotiating, approving and recommending to the Enertec shareholders
an unsolicited bona fide written Acquisition Proposal, for which adequate
financial arrangements have been made, which the Enertec board determines in
good faith (after consultation with its financial advisors, and after receiving
a written opinion of outside legal counsel to the effect that the Enertec board
is required to do so in order to discharge properly its fiduciary duties) would,
if consummated in accordance with its terms, result in a transaction financially
superior to the shareholders of Enertec than the transaction contemplated by the
Combination Agreement (a "Superior Proposal").
 
     Conditions to Closing.  The Combination Agreement provides that the
respective obligations of each party to complete the Transaction are subject to
a number of conditions, including the following material conditions:
 
     -  the Arrangement shall have been approved and adopted by the required
        votes of the Enertec shareholders and optionholders and VESI
        exchangeable shareholders;
 
     -  the Charter Amendment shall have been approved by the required vote of
        Veritas DGC stockholders and VESI exchangeable shareholders;
 
     -  all consents, including the Final Order (the "Final Order") of the Court
        of Queen's Bench of Alberta (the "Court") and any other regulatory
        approvals that are legally required for the consummation of the
        Transaction and the transactions contemplated by the Combination
        Agreement shall have occurred, been filed or been obtained;
 
                                       36
<PAGE>   50
 
     -  no order, decree or ruling or statute, rule, regulation or order shall
        be threatened, enacted, entered or enforced by any governmental agency
        that prohibits or renders illegal the consummation of the Transaction;
 
     -  there shall be no temporary restraining order, preliminary injunction,
        permanent injunction or other order preventing the consummation of the
        Transaction issued by any Canadian or U.S. federal, provincial or state
        court remaining in effect, nor shall any proceeding seeking any of the
        foregoing be pending;
 
     -  the representations and warranties of the parties shall be true and
        correct in all material respects as of the Effective Time as though made
        at and as of the Effective Time;
 
     -  the parties shall have performed in all material respects all agreements
        and covenants to be performed by them under the Combination Agreement;
 
     -  the parties shall have received legal opinions dated as of the closing
        date as to matters customary to transactions of the type contemplated by
        the Combination Agreement;
 
     -  the parties shall have received opinions from independent accountants to
        the effect that the Transaction will qualify for pooling of interests
        accounting treatment;
 
     -  the Series 1 Exchangeable Shares shall have been approved for listing on
        the TSE (a condition precedent to Enertec's obligation only);
 
     -  holders of no more than 5% of the Enertec Common Shares shall have
        notified Enertec of their intention to dissent from the Arrangement and
        the transactions contemplated thereby (a condition precedent to Veritas
        DGC's obligations only); and
 
     -  Enertec shall have received favorable tax opinions dated as of the
        closing date as to certain Canadian tax consequences of the Transaction
        (a condition precedent to Enertec's obligations only).
 
     Termination.  The Combination Agreement may be terminated by mutual
agreement of Enertec and Veritas DGC at any time prior to the Effective Time. In
addition, either Enertec or Veritas DGC may terminate the Combination Agreement
prior to the Effective Time if:
 
     -  there has been a breach of any representation, warranty, covenant or
        agreement contained in the Combination Agreement on the part of the
        other party, and such breach has not been cured within 15 business days
        after notice thereof;
 
     -  all conditions for closing the Transaction have not been satisfied or
        waived by August 15, 1999 (other than as a result of a breach by the
        terminating party);
 
     -  any required approval of the shareholders of Enertec or VESI or the
        stockholders of Veritas DGC shall not have been obtained; or
 
     -  any suit, action or other proceeding shall be pending or threatened by
        any governmental entity in which it is sought to restrain, prohibit or
        otherwise affect the consummation of the transactions contemplated by
        the Combination Agreement.
 
     Enertec may also terminate the Combination Agreement prior to the Effective
Time if the Enertec board determines in good faith that it is required by its
fiduciary duties to recommend to the Enertec shareholders that they vote against
the Arrangement and approve a Superior Proposal and either:
 
     -  Veritas DGC has not within five business days of receiving notice of
        Enertec's receipt of the Superior Proposal, revised its take-over
        proposal; or
 
     -  if Veritas DGC has revised its take-over proposal, the Enertec board
        determines in good faith that the Superior Proposal is more favorable to
        the Enertec shareholders than Veritas DGC's revised take-over proposal.
 
     Upon termination of the Combination Agreement in accordance with the terms
thereof, none of the parties or their respective officers or directors shall
have any further liability under the agreement, but no party shall be
 
                                       37
<PAGE>   51
 
released from any liability arising from the wilful breach by such party of any
of its representations, warranties or agreements contained in the agreement.
 
OTHER AGREEMENTS
 
     Enertec and Veritas DGC have entered into agreements with each of the
affiliates (as defined in Rule 145 under the United States Securities Act of
1933 (the "Securities Act")) of Enertec, pursuant to which such persons have
agreed that they will not sell, transfer, encumber or otherwise dispose of any
Enertec Common Shares prior to the Effective Time and that they will not sell,
transfer or encumber or otherwise dispose of any Series 1 Exchangeable Shares
and after the Effective Time until Veritas DGC shall have publicly released
financial statements that include at least thirty days of combined operating
results of Veritas DGC and Enertec.
 
     Enertec and Veritas DGC have also entered into agreements with each of the
Veritas DGC affiliates, pursuant to which such persons have agreed that they
will not sell, transfer, encumber or otherwise dispose of any shares of Veritas
DGC Common Stock or VESI Exchangeable Shares prior to the Effective Time and
after the Effective Time until Veritas DGC shall have publicly released
financial statements that include at least thirty days of combined operating
results of Veritas DGC and Enertec.
 
     In addition, the Enertec affiliates have agreed that they will not sell,
pledge or otherwise dispose of any Series 1 Exchangeable Shares unless: (1) such
transaction is permitted pursuant to the provisions of Rule 145 under the
Securities Act; (2) a registration statement covering the transaction shall have
been filed with the SEC and made effective under the act, or (3) such
transaction is permitted under an exemption from registration under the act.
 
COURT APPROVAL OF THE ARRANGEMENT AND COMPLETION OF THE TRANSACTION
 
     An arrangement of a corporation under the ABCA requires approval by both
the Court and the shareholders, and, if applicable, optionholders of the subject
corporation. Prior to the mailing of this Joint Proxy Statement, Enertec and
VESI obtained the Interim Order of the Court, which is attached as Annex C (the
"Interim Order"), providing for the calling and holding of the Enertec meeting,
the VESI meeting and other procedural matters. The Notice of Petition for the
Final Order appears at the front of this Joint Proxy Statement.
 
     Subject to the approval of the Arrangement by the Enertec shareholders and
Enertec optionholders at the Enertec meeting and by the VESI exchangeable
shareholders at the VESI meeting, the hearing in respect of the Final Order is
scheduled to take place on           , 1999 at      a.m. (Calgary time) in the
Court at the Court House, 611 4th Street S.W., Calgary, Alberta, Canada. All
Enertec shareholders, Enertec optionholders and VESI exchangeable shareholders
who wish to participate or be represented or to present evidence or arguments at
that hearing must serve and file a notice of appearance as set out in the Notice
of Petition for the Final Order and satisfy any other requirements. At the
hearing of the application in respect of the Final Order, the Court will
consider, among other things, the fairness and reasonableness of the
Arrangement. The Court may approve the Arrangement as proposed or as amended in
any manner the Court may direct, subject to compliance with such terms and
conditions, if any, as the Court deems fit.
 
     Assuming the Final Order is granted and the other conditions to the
Combination Agreement are satisfied or waived, it is anticipated that the
following will occur substantially simultaneously: Articles of Arrangement will
be filed with the Registrar under the ABCA to give effect to the Arrangement,
the Support Agreement between VESI and Veritas DGC substantially in the form of
Annex E (the "Support Agreement") and the Voting and Exchange Trust Agreement
between VESI, Veritas DGC and CIBC Mellon Trust Company (the "Trustee")
substantially in the form of Annex F (the "Voting and Exchange Trust Agreement")
will be executed and delivered, and the various other documents necessary to
close the Combination Agreement will be executed and delivered.
 
     Subject to the foregoing, it is presently anticipated that the Transaction
will be completed, and the Effective Time will occur, on or about June 30, 1999.
 
                                       38
<PAGE>   52
 
ANTICIPATED ACCOUNTING TREATMENT
 
     The Arrangement is anticipated to be accounted for using the pooling of
interests method of accounting under U.S. GAAP. Under the pooling of interests
method of accounting, the assets, liabilities and shareholders' equity and the
operating results of Veritas DGC and Enertec will be carried forward by Veritas
DGC at their recorded amounts and, therefore, there is no recognition of
additional goodwill relating to either Veritas DGC or Enertec required in
connection with the Transaction.
 
     Veritas DGC and Enertec have entered into affiliates agreements with each
Veritas DGC affiliate and Enertec affiliate. See "-- Other Agreements." Such
agreements relate to the ability of Veritas DGC to account for the Transaction
as a pooling of interests under U.S. GAAP.
 
PROCEDURES FOR TRANSFER BY ENERTEC SHAREHOLDERS AND ENERTEC OPTIONHOLDERS
 
     Enertec Shareholders.  Enclosed with copies of this Joint Proxy Statement
delivered to the registered holders of Enertec Common Shares is an Enertec
letter of transmittal which, when duly completed and returned together with a
certificate for Enertec Common Shares, shall enable each Enertec shareholder to
receive Series 1 Exchangeable Shares equal to the number of Enertec Common
Shares held by such shareholder multiplied by the Exchange Ratio. See "--
Transaction Mechanics."
 
     No certificates representing fractional Series 1 Exchangeable Shares will
be issued. In lieu of fractional Series 1 Exchangeable Shares, each Enertec
shareholder who would otherwise be entitled to receive a fraction of a Series 1
Exchangeable Share shall be paid by VESI an amount of cash (rounded to the
nearest whole cent) equal to the Canadian dollar equivalent product of (1) such
fraction, multiplied by (2) the average closing price of the Veritas DGC Common
Stock on the NYSE for the ten trading days ended on the last trading date prior
to the Effective Date.
 
     Any use of the mails to transmit a certificate for Enertec Common Shares
and a related Enertec letter of transmittal is at the risk of the Enertec
shareholder. If these documents are mailed, it is recommended that registered
mail, with return receipt requested, properly insured, be used.
 
     If the Transaction is completed, certificates representing the appropriate
number of Series 1 Exchangeable Shares issuable to a former Enertec shareholder
who has complied with the procedures set out above, together with a cheque in
the amount, if any, payable in lieu of fractional Series 1 Exchangeable Shares
will, as soon as practicable after the later of the Effective Date and the date
of receipt of a certificate for Enertec Common Shares and a related Enertec
letter of transmittal, be (1) forwarded to the holder at the address specified
in the Enertec letter of transmittal by first class mail or (2) made available
at the offices of CIBC Mellon Trust Company for pickup by the holder, if
requested by the holder in the Enertec letter of transmittal.
 
     Enertec shareholders will be entitled to make an income tax election
pursuant to subsection 85(1) of the Canadian Tax Act with respect to the
transfer of their Enertec Common Shares to VESI by providing two signed copies
of the necessary election forms to VESI within 90 days following the Effective
Date, duly completed with the details of the number of shares transferred and
the applicable agreed amounts for the purposes of such elections. Thereafter,
subject to the election forms complying with the provisions of the Canadian Tax
Act, the forms will be signed by VESI and returned to such Enertec shareholders
for filing with Revenue Canada.
 
     If the Transaction does not close, all certificates representing Enertec
Common Shares transmitted with a related Enertec letter of transmittal will be
returned to Enertec shareholders.
 
     Where a certificate for Enertec Common Shares has been destroyed, lost or
mislaid, the registered holder of that certificate should immediately contact
Montreal Trust Company of Canada regarding the issuance of a replacement
certificate upon the holder satisfying such requirements as may be imposed by
Enertec in connection with issuance of the replacement certificate.
 
     Enertec Optionholders.  Each outstanding Enertec Option will be
automatically exchanged for a Veritas DGC Option at the Effective Date in
accordance with the terms of the Combination Agreement and the Arrangement,
without any action on the part of the Enertec optionholders. Promptly after the
Effective Time,
 
                                       39
<PAGE>   53
 
Veritas DGC will notify each Enertec optionholder of such exchange, with any
relevant information, and the United States dollar exercise price of such
exchanged option.
 
STOCK EXCHANGE LISTINGS
 
     The Veritas DGC Common Stock currently trades on the NYSE and the TSE. The
NYSE has approved the listing on the Effective Date, subject to notice of
issuance, of the Veritas DGC Common Stock issuable upon the exchange of Series 1
Exchangeable Shares, and on the exercise of Veritas DGC Options. The TSE has
accepted notice of the proposed Arrangement and has conditionally approved the
listing and posting for trading on the Effective Date of the Series 1
Exchangeable Shares, and the Veritas DGC Common Stock issuable upon the exchange
of Series 1 Exchangeable Shares and upon the exercise of Veritas DGC Options.
 
ELIGIBILITY FOR INVESTMENT IN CANADA
 
     Series 1 Exchangeable Shares.  The Series 1 Exchangeable Shares, provided
they are listed on a prescribed stock exchange in Canada (which currently
includes the TSE) and provided that VESI maintains a substantial presence in
Canada, will not be foreign property under the Canadian Tax Act for trusts
governed by registered retirement savings plans, registered retirement income
funds and deferred profit sharing plans, for registered pension plans or for
certain other persons to whom Part XI of the Canadian Tax Act apply.
 
     The Series 1 Exchangeable Shares will be qualified investments under the
Canadian Tax Act for trusts governed by registered retirement savings plans,
registered retirement income funds and deferred profit sharing plans.
 
     Veritas DGC has indicated that it intends to use its best efforts to cause
VESI to maintain the listing of the Series 1 Exchangeable Shares on the TSE.
 
     Voting Rights and Exchange Rights.  The rights of the holders of Series 1
Exchangeable Shares to direct the voting of the one share of ERS Special Voting
Stock (the "Voting Share") by the Trustee (the "Voting Rights") and the rights
granted to the Trustee to exchange Series 1 Exchangeable Shares for Veritas DGC
Common Stock in certain circumstances (the "Exchange Rights") will not be
qualified investments and will be foreign property under the Canadian Tax Act.
However, as indicated under "Canadian Federal Income Tax Considerations to
Enertec Shareholders -- Shareholders Resident in Canada," each of Veritas DGC
and VESI is of the view that the fair market value of these rights is nominal.
 
     Veritas DGC Common Stock.  The Veritas DGC Common Stock will be a qualified
investment under the Canadian Tax Act for trusts governed by registered
retirement savings plans, registered retirement income funds and deferred profit
sharing plans provided such shares remain listed on the NYSE or another
prescribed stock exchange. The Veritas DGC Common Stock will be foreign property
under the Canadian Tax Act.
 
REGULATORY MATTERS
 
     The Transaction is subject to the premerger filing requirements of the
United States Hart-Scott-Rodino Antitrust Improvements Act of 1976 and, on April
12, 1999, Veritas DGC and Enertec made premerger filings under the act with the
Federal Trade Commission and the Antitrust Division of the Department of
Justice. The Transaction is subject to termination of the waiting period under
the act.
 
RESALE OF SERIES 1 EXCHANGEABLE SHARES AND VERITAS DGC COMMON STOCK RECEIVED IN
THE TRANSACTION
 
     United States.  The issuance of Series 1 Exchangeable Shares to holders of
Enertec Common Shares will not be registered under the Securities Act. Such
shares will be issued in reliance upon the exemption available pursuant to
Section 3(a)(10) of the Securities Act. Section 3(a)(10) exempts securities
issued in exchange for one or more outstanding securities from the general
requirement of registration where the terms and conditions of the issuance and
exchange of such securities have been approved by any court of competent
jurisdiction, after a hearing upon the fairness of the terms and conditions of
the issuance and exchange at which all persons to whom such securities will be
issued have the right to appear. The Court is authorized to conduct a hearing to
determine the fairness of the terms and conditions of the Arrangement, including
the proposed issuance of securities in
                                       40
<PAGE>   54
 
exchange for other outstanding securities. The Court entered the Interim Order
on           , 1999 and subject to the approval of the Arrangement by the
Enertec shareholders and the VESI exchangeable shareholders, a hearing on the
fairness of the Arrangement will be held on           , 1999 by the Court. See
"-- Court Approval of the Arrangement and Completion of the Transaction."
Veritas DGC, VESI and Enertec believe that the issuance by VESI of the Series 1
Exchangeable Shares in exchange for the Enertec Common Shares is exempt under
Section 3(a)(10) of the Securities Act and that they will receive a letter from
the SEC confirming that the staff of the SEC will not recommend any enforcement
action with respect to such issuance.
 
     The Series 1 Exchangeable Shares will be freely transferable under U.S.
federal securities laws, except by persons who are affiliates of Enertec prior
to the Transaction. Shares held by such affiliates may be resold by them only in
transactions permitted by the resale provisions of Rule 145(d)(1), (2), or (3)
promulgated under the Securities Act or as otherwise permitted under the
Securities Act. Rule 145(d)(1) generally provides that affiliates of Enertec may
not sell securities of Veritas DGC received in the Arrangement unless pursuant
to an effective registration statement or unless pursuant to the volume, current
public information, manner of sale and timing limitations of Rule 144. These
limitations generally require that any sales made by an affiliate in any
three-month period not exceed the greater of 1% of the outstanding shares of
Veritas DGC or the average weekly trading volume over the four calendar weeks
preceding the placement of the sell order and that such sales be made in
unsolicited, open market "brokers transactions." Rules 145(d)(2) and (3)
generally provide that the foregoing limitations lapse for non-affiliates of
Veritas DGC after a period of one or two years, respectively, depending upon
whether certain currently available information continues to be available with
respect to Veritas DGC.
 
     Veritas DGC has agreed that it will file and maintain effective a Form S-3
registration statement covering the issuance of the Veritas DGC Common Stock
from time to time in exchange for the Series 1 Exchangeable Shares. The shares
of Veritas DGC Common Stock issued from time to time in exchange for the Series
1 Exchangeable Shares therefore will be freely transferable under U.S. federal
securities laws, subject to restrictions on persons who are affiliates of
Veritas DGC.
 
     Canada.  Veritas DGC, VESI and Enertec have applied for and expect to
receive rulings or orders of certain provincial securities regulatory
authorities in Canada to permit the issuance to Enertec shareholders of the
Series 1 Exchangeable Shares and to permit resale of such shares in such
provinces without restriction by a shareholder other than a "control person,"
provided that no unusual effort is made to prepare the market for any such
resale or to create a demand for the securities which are the subject of any
such resale and no extraordinary commission or consideration is paid in respect
thereof. Applicable Canadian securities legislation provides a rebuttable
presumption that a person or company is a control person in relation to an
issuer where the person or company alone or in combination with others holds
more than 20% of the outstanding voting securities of the issuer.
 
     Veritas DGC, VESI and Enertec have also applied for rulings or orders of
certain provincial securities regulatory authorities in Canada to permit the
issuance of Veritas DGC Common Stock to holders of Series 1 Exchangeable Shares,
and to permit the resale of Veritas DGC Common Stock by such holders without the
requirement of filing a prospectus.

                      THE COMPANIES AFTER THE TRANSACTION
 
THE COMBINATION -- GENERAL
 
     Upon completion of the Transaction, the parent company of the combined
entity will be Veritas DGC, which will continue to be a corporation governed by
the DGCL. Its principal executive office will continue to be located at 3701
Kirby Drive, Houston, Texas 77098 (telephone number (713) 512-8300). Veritas DGC
owns all of the voting securities of VESI, a corporation governed by the ABCA.
VESI will own all of the voting securities of Enertec. After the Effective Time,
Enertec will continue to be a corporation governed by the ABCA.
 
VERITAS DGC CAPITAL STOCK
 
     In the event of the consummation of the Transaction, which requires the
adoption by the Veritas DGC stockholders of the Charter Amendment, the capital
stock of Veritas DGC will be as summarized below.
 
     The Veritas DGC Restated Certificate of Incorporation authorizes 40,000,000
ordinary shares, consisting of a series of one share of VESI Special Voting
Stock and all other shares being designated as common stock, and 1,000,000
shares of Veritas DGC Preferred Stock. If the Charter Amendment is approved, the
Veritas DGC Restated Certificate of Incorporation will authorize an additional
series of ordinary shares, consisting of one share designated as ERS Special
Voting Stock.
 
     Veritas DGC Common Stock.  Shares of Veritas DGC Common Stock have a par
value of U.S. $0.01 per share. The holders of Veritas DGC Common Stock are
entitled to one vote for each share held of record on all matters submitted to a
vote of stockholders. Cumulative voting for the election of directors is not
authorized by the Veritas DGC Restated Certificate of Incorporation. The holders
of Veritas DGC Common Stock are entitled to receive such dividends as may be
declared by the Veritas DGC board of directors out of funds legally available
therefor and are entitled upon any liquidation, dissolution or winding-up of
Veritas DGC to receive rateably the net assets of Veritas DGC available for
distribution. No pre-emptive rights, conversion rights, redemption rights or
sinking fund provisions are applicable to the Veritas DGC Common Stock.
 
     As of March 31, 1999, 21,204,380 shares of Veritas DGC Common Stock were
issued and outstanding.
 
     VESI Special Voting Stock.  A single share of VESI Special Voting Stock is
authorized as a series of ordinary shares for issuance and a single share is
outstanding having a par value of U.S. $.01 per share. Except as otherwise
required by law or the Veritas DGC Restated Certificate of Incorporation, the
voting share possesses a number of votes equal to the number of outstanding VESI
Exchangeable Shares from time to time not owned by Veritas DGC or any entity
controlled by Veritas DGC for the election of directors and on all other matters
submitted to a vote of stockholders of Veritas DGC. The holders of Veritas DGC
Common Stock, the holder of the ERS Special Voting Stock and the holder of the
voting share vote together as a single class on all matters. In the event of any
liquidation, dissolution or winding up of Veritas DGC, the holder of the voting
share is not entitled to receive any assets of Veritas DGC available for
distribution to its stockholders. The holder of the voting share is not entitled
to receive dividends. At such time as the voting share has no votes attached to
it because there are no VESI Exchangeable Shares outstanding not owned by
Veritas DGC or an entity controlled by Veritas DGC, and there are no shares of
stock, debt, options or other agreements of Veritas DGC that could give rise to
the issuance of any VESI Exchangeable Shares to any person (other than Veritas
DGC or an entity controlled by Veritas DGC), the voting share will be canceled.
 
     ERS Special Voting Stock.  A single share of ERS Special Voting Stock will
be authorized as a series of ordinary shares for issuance and a single share
will be outstanding having a par value of U.S. $.01 per share. Except as
otherwise required by law or the Veritas DGC Restated Certificate of
Incorporation, the Voting Share will possess a number of votes equal to the
number of outstanding Series 1 Exchangeable Shares from time to time not owned
by Veritas DGC or any entity controlled by Veritas DGC for the election of
directors and on all other matters submitted to a vote of stockholders of
Veritas DGC. The holders of Veritas DGC Common Stock, the holder of the VESI
Special Voting Stock and the holder of the voting share will vote together as a
single class on all matters. In the event of any liquidation, dissolution or
winding-up of Veritas DGC, the holder of the voting share will not be entitled
to receive any assets of Veritas DGC available for distribution to its
stockholders. The holder of the voting share will not be entitled to receive
dividends. Pursuant to the Combination Agreement, the
                                       42
<PAGE>   56
 
voting share will be issued to CIBC Mellon Trust Company (the "Trustee") as
trustee under the Voting and Exchange Trust Agreement. See "-- Voting and
Exchange Trust Agreement." At such time as the voting share has no votes
attached to it because there are no Series 1 Exchangeable Shares outstanding not
owned by Veritas DGC or an entity controlled by Veritas DGC, and there are no
shares of stock, debt, options or other agreements of VESI that could give rise
to the issuance of any Series 1 Exchangeable Shares to any person (other than
Veritas DGC or an entity controlled by Veritas DGC), the voting share will be
canceled.
 
     Veritas DGC Preferred Stock.  Shares of Veritas DGC Preferred Stock have a
par value of U.S. $0.01 per share. One million shares of preferred stock are
presently authorized. The Veritas DGC board of directors will continue to be
authorized to provide for the issuance of shares of preferred stock in one or
more series, and to establish from time to time the number of shares to be
included in each such series, to fix the designation, powers, preferences and
rights of the shares of each such series and any qualifications, limitations or
restrictions thereof. No series of such stock has been designated.
 
     Although the Veritas DGC board of directors has no present intention of
doing so, it could issue a series of Veritas DGC Preferred Stock that could,
depending on the terms of such series, provide for a liquidation preference over
the Veritas DGC Common Stock or impede the completion of a merger, tender offer
or other takeover attempt. The Veritas DGC board of directors, in so acting,
could issue Veritas DGC Preferred Stock having terms that could discourage an
acquisition attempt through which an acquiror may be otherwise able to change
the composition of the board of directors, including a tender or exchange offer
or other transaction that some, or a majority, of Veritas DGC's stockholders
might otherwise believe to be in their best interests.
 
VESI SHARE CAPITAL
 
     The following is a summary description of the share capital of VESI and is
qualified in its entirety by reference to the Plan of Arrangement, Class A
Exchangeable Share provisions and Series 1 Exchangeable Share provisions
attached as Annex D hereto. In the event of the consummation of the Transaction,
the share capital of VESI after the Effective Time will have the rights and
preferences summarized below.
 
     COMMON SHARES OF VESI
 
     The holders of VESI Common Shares will be entitled to receive notice of and
to attend all meetings of the shareholders of VESI and will be entitled to one
vote for each share held of record on all matters submitted to a vote of holders
of VESI Common Shares. The holders of VESI Common Shares will be entitled to
receive such dividends as may be declared by the VESI board of directors out of
funds legally available therefor. Holders of VESI Common Shares will be entitled
upon any liquidation, dissolution or winding-up of VESI, subject to the prior
rights of the holders of the VESI Exchangeable Shares and the Class A
Exchangeable Shares (including the Series 1 Exchangeable Shares) and to any
other shares ranking senior to the VESI Common Shares, to receive the remaining
property and assets of VESI rateably with the holders of the VESI Common Shares.
 
     As of March 31, 1999, one VESI Common Share was issued and outstanding.
 
     EXCHANGEABLE SHARES OF VESI
 
     The VESI Exchangeable Shares rank prior to the VESI Common Shares and any
other shares ranking junior to the VESI Exchangeable Shares, and will rank on a
parity with the Class A Exchangeable Shares (including the Series 1 Exchangeable
Shares), with respect to the payment of dividends and the distribution of assets
in the event of the liquidation, dissolution or winding-up of VESI. The VESI
Exchangeable Share provisions are, otherwise, substantially similar to the
Series 1 Exchangeable Share provisions described below, except that the
automatic redemption date for the VESI Exchangeable Shares is initially set at
August 30, 2014 (and not later than August 30, 2021).
 
     As of March 31, 1999, 1,506,663 VESI Exchangeable Shares were issued and
outstanding (excluding VESI Exchangeable Shares held by Veritas DGC).

<PAGE>   57
 
     CLASS A EXCHANGEABLE SHARES OF VESI
 
     The Class A Exchangeable Shares are issuable in series, each series to
consist of such number of shares, and to have such designation, rights,
privileges, restrictions and conditions attaching thereto, as determined by the
VESI board. The Class A Exchangeable Shares of each series shall rank on a
parity with the VESI Exchangeable Shares and the Class A Exchangeable Shares of
every other series, and shall be entitled to a preference over the VESI Common
Shares and any other shares ranking junior to the Class A Exchangeable Shares,
with respect to the payment of dividends and the distribution of the assets of
VESI in the event of the liquidation, dissolution or winding-up of VESI. Except
as required by applicable law and the provisions of any series of Class A
Exchangeable Shares, the holders of the Class A Exchangeable Shares shall not be
entitled to receive notice of or to attend any meeting of the shareholders of
VESI or to vote at any such meeting.
 
     SERIES 1 EXCHANGEABLE SHARES OF VESI
 
     Ranking.  The Series 1 Exchangeable Shares will rank on a parity with the
VESI Exchangeable Shares and the Class A Exchangeable Shares of every other
series and will rank prior to the VESI Common Shares and any other shares
ranking junior to the Series 1 Exchangeable Shares with respect to the payment
of dividends and the distribution of assets in the event of the liquidation,
dissolution or winding-up of VESI.
 
     Dividends.  Holders of Series 1 Exchangeable Shares will be entitled to
receive dividends equivalent to dividends paid from time to time by Veritas DGC
on shares of Veritas DGC Common Stock. The declaration date, record date and
payment date for dividends on the Series 1 Exchangeable Shares will be the same
as that for the corresponding dividends on the Veritas DGC Common Stock.
 
     Certain Restrictions.  Without the approval of the holders of the Series 1
Exchangeable Shares, VESI will not:
 
     -  pay any dividend on the VESI Common Shares, or any other shares ranking
        junior to the Series 1 Exchangeable Shares, other than stock dividends
        payable in such other shares ranking junior to the Series 1 Exchangeable
        Shares;
 
     -  redeem, purchase or make any capital distribution in respect of VESI
        Common Shares or any other shares ranking junior to the Series 1
        Exchangeable Shares;
 
     -  except as provided for in the rights, privileges, restrictions and
        conditions attaching to the VESI Exchangeable Shares or Class A
        Exchangeable Shares, or any series thereof, redeem or purchase any other
        shares of VESI ranking equally with the Series 1 Exchangeable Shares
        with respect to the payment of dividends or on any liquidation
        distribution;
 
     -  issue any Series 1 Exchangeable Shares other than by stock dividends to
        the holders of the Series 1 Exchangeable Shares or as contemplated in
        the Support Agreement; or
 
     -  except for the designation of one or more further series of the Class A
        Exchangeable Shares, amend the articles or bylaws of VESI.
 
     The restrictions in the first three points above will not apply at any time
when the dividends on the outstanding Series 1 Exchangeable Shares corresponding
to dividends declared on the Veritas DGC Common Stock have been declared and
paid in full.
 
     Liquidation.  In the event of the liquidation, dissolution or winding-up of
VESI, a holder of Series 1 Exchangeable Shares will be entitled to receive for
each Series 1 Exchangeable Share one share of Veritas DGC Common Stock, together
with a cash amount equivalent to the full amount of all unpaid dividends on the
Series 1 Exchangeable Shares. See "-- Voting and Exchange Trust Agreement."
 
     Retraction of Series 1 Exchangeable Shares by Holders.  A holder of Series
1 Exchangeable Shares will be entitled at any time to require VESI to redeem any
or all of the Series 1 Exchangeable Shares held by such holder for one share of
Veritas DGC Common Stock for each Series 1 Exchangeable Share plus an additional
amount equivalent to the full amount of all unpaid dividends thereon, which
shall be delivered to the retracting holder on
 
                                       44
<PAGE>   58
 
the retraction date specified by the holder (which shall not be less than five
nor more than ten business days after the date on which VESI receives the
retraction request from the holder).
 
     If, as a result of liquidity or solvency provisions of applicable law, VESI
is not permitted to redeem all Series 1 Exchangeable Shares tendered by a
retracting holder, VESI will redeem only those Series 1 Exchangeable Shares
tendered by the holder (rounded to the next lower multiple of 100 shares) as
would not be contrary to such provisions of applicable law. The holder of any
Series 1 Exchangeable Shares not redeemed by VESI will be deemed to have
required Veritas DGC to purchase such unretracted shares in exchange for Veritas
DGC Common Stock, plus an additional amount equivalent to the full amount of all
unpaid dividends thereon, on the retraction date pursuant to the optional
Exchange Rights. See "-- Voting and Exchange Trust Agreement."
 
     Redemption of Series 1 Exchangeable Shares.  On the 10th anniversary of the
Effective Date, unless such date shall be extended to a specified later date by
the VESI board of directors, not to be later than the 15th anniversary of the
Effective Date, or such earlier date as specified by the VESI board of directors
if:
 
     -  there are fewer than 10,000 Series 1 Exchangeable Shares outstanding
        (other than Series 1 Exchangeable Shares held by Veritas DGC and
        entities controlled by Veritas DGC); or
 
     -  if at any time after the 5th anniversary there are fewer than 250,000
        VESI Exchangeable Shares outstanding (other than VESI Exchangeable
        Shares held by Veritas DGC and entities controlled by Veritas DGC) and
        Veritas DGC exercises its option to redeem all of such outstanding VESI
        Exchangeable Shares,
 
VESI must redeem all but not less than all of the then outstanding Series 1
Exchangeable Shares in exchange for an equal number of shares of Veritas DGC
Common Stock, plus an additional amount equivalent to the full amount of all
declared and unpaid dividends on such Series 1 Exchangeable Shares. However,
Veritas DGC will have the overriding right to purchase on the Automatic
Redemption Date all but not less than all of the outstanding Series 1
Exchangeable Shares in exchange for one share of Veritas DGC Common Stock for
each such Series 1 Exchangeable Share, plus an additional amount equivalent to
the full amount of all declared and unpaid dividends on such Series 1
Exchangeable Share. VESI shall, at least 120 days before the Automatic
Redemption Date, provide the registered holders of Series 1 Exchangeable Shares
with written notice of the proposed redemption of the Series 1 Exchangeable
Shares by VESI.
 
     Voting Rights.  Except as required by applicable law, the holders of the
Series 1 Exchangeable Shares shall not be entitled as such to receive notice of
or attend any meeting of the shareholders of VESI or to vote at any such
meeting.
 
     Amendment and Approval.  The rights, privileges, restrictions and
conditions attaching to the Series 1 Exchangeable Shares may be changed only
with the approval of the holders thereof. Any such approval or any other
approval or consent to be given by the holders of the Series 1 Exchangeable
Shares will be sufficiently given if given in accordance with applicable law and
subject to a minimum requirement that such approval or consent be evidenced by a
resolution passed by not less than two-thirds of the votes cast thereon (other
than shares beneficially owned by Veritas DGC or entities controlled by Veritas
DGC) at a meeting of the holders of Series 1 Exchangeable Shares duly called and
held at which holders of at least 50% of the then outstanding Series 1
Exchangeable Shares are present or represented by proxy. In the event that no
such quorum is present at such meeting within one-half hour after the time
appointed therefor, then the meeting will be adjourned to such place and time
not less than 10 days later as may be determined at the original meeting, and
the holders of Series 1 Exchangeable Shares present or represented by proxy at
the adjourned meeting may transact the business for which the meeting was
originally called. At the adjourned meeting, a resolution passed by the
affirmative vote of not less than two-thirds of the votes cast thereon will
constitute the approval or consent of the holders of the Series 1 Exchangeable
Shares.
 
     Actions of VESI under Support Agreement.  Under the Series 1 Exchangeable
Share provisions, VESI will agree to take all such actions and do all such
things as are necessary or advisable to perform and comply with its obligations
under, and to ensure the performance and compliance by Veritas DGC with its
obligations under, the Support Agreement.

SUPPORT AGREEMENT
 
     The following is a summary description of the material provisions of the
Support Agreement and is qualified in its entirety by reference to the full text
of the Support Agreement, which is attached as Annex E.
 
     Under the Support Agreement, Veritas DGC will agree that:
 
     -  it will not declare or pay dividends on the Veritas DGC Common Stock
        unless VESI is able to and simultaneously pays an equivalent dividend on
        the Series 1 Exchangeable Shares;
 
     -  it will cause VESI to declare and pay an equivalent dividend on the
        Series 1 Exchangeable Shares simultaneously with Veritas DGC's
        declaration and payment of dividends on the Veritas DGC Common Stock;
 
     -  it will advise VESI in advance of the declaration of any dividend on the
        Veritas DGC Common Stock and ensure that the declaration date, record
        date and payment date for dividends on the Series 1 Exchangeable Shares
        are the same as that for the Veritas DGC Common Stock;
 
     -  it will take all actions and do all things necessary to ensure that VESI
        is able to provide to the holders of the Series 1 Exchangeable Shares
        the equivalent number of shares of Veritas DGC Common Stock in the event
        of a liquidation, dissolution, or winding-up of VESI, a retraction
        request by a holder of Series 1 Exchangeable Shares, or a redemption of
        Series 1 Exchangeable Shares of VESI; and
 
     -  it will not vote or otherwise take any action or omit to take any action
        causing the liquidation, dissolution or winding-up of VESI.
 
     The Support Agreement will also provide that, without the prior approval of
VESI and the holders of the Series 1 Exchangeable Shares, Veritas DGC will not
distribute additional shares of Veritas DGC Common Stock or rights to subscribe
therefor or other property or assets to all or substantially all holders of
shares of Veritas DGC Common Stock, nor change the Veritas DGC Common Stock nor
effect any tender offer, share exchange offer, issuer bid, take-over bid or
similar transaction affecting the Veritas DGC Common Stock, unless the same or
an equivalent distribution on or change to the Series 1 Exchangeable Shares (or
in the rights of the holders thereof) is made simultaneously.
 
     Veritas DGC has agreed that so long as there remain outstanding any Series
1 Exchangeable Shares not owned by Veritas DGC or any entity controlled by
Veritas DGC, Veritas DGC will remain the beneficial owner, directly or
indirectly, of all outstanding shares of VESI other than the VESI Exchangeable
Shares and the Class A Exchangeable Shares (including the Series 1 Exchangeable
Shares).
 
     With the exception of administrative changes for the purpose of adding
covenants for the protection of the holders of the Series 1 Exchangeable Shares,
making certain necessary amendments or curing ambiguities or clerical errors (in
each case provided that the board of directors of each of Veritas DGC and VESI
is of the opinion that such amendments are not prejudicial to the interests of
the holders of the Series 1 Exchangeable Shares), the Support Agreement may not
be amended without the approval of the holders of the Series 1 Exchangeable
Shares.
 
     Under the Support Agreement, Veritas DGC has agreed not to exercise any
voting rights attached to the Series 1 Exchangeable Shares owned by it or any
entity controlled by it on any matter considered at meetings of holders of
Series 1 Exchangeable Shares (including any approval sought from such holders in
respect of matters arising under the Support Agreement).
 
     In order for Veritas DGC to perform in accordance with the Support
Agreement, VESI must notify Veritas DGC of the occurrence of certain events,
such as the liquidation, dissolution or winding-up of VESI, and VESI's receipt
of a retraction request from a holder of Series 1 Exchangeable Shares.

VOTING AND EXCHANGE TRUST AGREEMENT
 
     The following is a summary description of the material provisions of the
Voting and Exchange Trust Agreement and is qualified in its entirety by
reference to the full text of the Voting and Exchange Trust Agreement which is
attached as Annex F.
 
     Under the terms of the Voting and Exchange Trust Agreement, Veritas DGC
will issue and grant to the Trustee the Voting Rights and the Exchange Rights.
The Voting Rights, the Exchange Rights and all other rights and benefits
received by the Enertec shareholders (excluding Series 1 Exchangeable Shares)
(the "Ancillary Rights") in connection with the consummation of the Arrangement
shall be solely in consideration of the provision by such holders of the Veritas
DGC Consideration to Veritas DGC.
 
     Voting Rights.  Under the Voting and Exchange Trust Agreement, Veritas DGC
will issue the Voting Share to the Trustee for the benefit of the holders (other
than Veritas DGC and its subsidiaries) of the Series 1 Exchangeable Shares. The
Voting Share will carry a number of votes, exercisable at any meeting at which
Veritas DGC stockholders are entitled to vote, equal to the number of
outstanding Series 1 Exchangeable Shares (other than shares held by Veritas DGC
and its subsidiaries). With respect to any written consent sought from the
Veritas DGC stockholders, each vote attached to the Voting Share will be
exercisable in the same manner as set forth above.
 
     Each holder of a Series 1 Exchangeable Share on the record date for any
meeting at which Veritas DGC stockholders are entitled to vote will be entitled
to instruct the Trustee to exercise one of the votes attached to the Voting
Share for such Series 1 Exchangeable Share. The Trustee will exercise each vote
attached to the Voting Share only as directed by the relevant holder and, in the
absence of instructions from a holder as to voting, will not exercise such
votes. A holder may, upon instructing the Trustee, obtain a proxy from the
Trustee entitling the holder to vote directly at the relevant meeting the votes
attached to the Voting Share to which the holder is entitled.
 
     The Trustee will send to the holders of the Series 1 Exchangeable Shares
the notice of each meeting at which the Veritas DGC stockholders are entitled to
vote, together with the related meeting materials and a statement as to the
manner in which the holder may instruct the Trustee to exercise the votes
attaching to the Voting Share, at the same time as Veritas DGC sends such notice
and materials to the Veritas DGC stockholders. The Trustee will also send to the
holders copies of all information statements, interim and annual financial
statements, reports and other materials sent by Veritas DGC to the Veritas DGC
stockholders at the same time as such materials are sent to the Veritas DGC
stockholders. To the extent such materials are provided to the Trustee by
Veritas DGC, the Trustee will also send to the holders all materials sent by
third parties to Veritas DGC stockholders, including dissident proxy circulars
and tender and exchange offer circulars, as soon as possible after such
materials are first sent to Veritas DGC stockholders.
 
     All rights of a holder of Series 1 Exchangeable Shares to exercise votes
attached to the Voting Share will cease upon the exchange of all such holder's
Series 1 Exchangeable Shares for shares of Veritas DGC Common Stock.
 
     Exchange Rights.  Under the Voting and Exchange Trust Agreement, Veritas
DGC will grant the Exchange Rights to the Trustee for the benefit of the holders
of the Series 1 Exchangeable Shares.
 
     Optional Exchange Right.  Upon the occurrence and during the continuance of
an VESI Insolvency Event (as defined below), a holder of Series 1 Exchangeable
Shares will be entitled to instruct the Trustee to exercise the optional
Exchange Right with respect to any or all of the Series 1 Exchangeable Shares
held by such holder, thereby requiring Veritas DGC to purchase such Series 1
Exchangeable Shares from the holder. Immediately upon the occurrence of a VESI
Insolvency Event or any event which may with the passage of time or the giving
of notice, become a VESI Insolvency Event, VESI and Veritas DGC will give
written notice thereof to the Trustee. As soon as practicable thereafter, the
Trustee will notify each holder of Series 1 Exchangeable Shares of such event or
potential event and will advise the holder of its rights with respect to the
optional Exchange Right. In this Joint Proxy Statement, "VESI Insolvency Event"
means any insolvency or bankruptcy proceeding instituted by or against VESI,
including any such proceeding under the Companies' Creditors Arrangement Act
(Canada) and the Bankruptcy and Insolvency Act (Canada), the admission in
writing by VESI of its inability to
                                       47
<PAGE>   61
 
pay its debts generally as they become due and the inability of VESI, as a
result of solvency requirements of applicable law, to redeem any Series 1
Exchangeable Shares, other Class A Exchangeable Shares or VESI Exchangeable
Shares tendered for retraction.
 
     The consideration for each Series 1 Exchangeable Share to be acquired under
the optional Exchange Right will be one share of Veritas DGC Common Stock plus
an additional amount equivalent to the full amount of all dividends declared and
unpaid on the Series 1 Exchangeable Share. Veritas DGC shall be entitled to
liquidate some of the Veritas DGC Common Stock that would otherwise be
deliverable to the particular holder in order to fund any statutory withholding
tax obligation.
 
     If, as a result of liquidity or solvency provisions of applicable law, VESI
is unable to redeem all of the Series 1 Exchangeable Shares tendered for
retraction by a holder in accordance with the Series 1 Exchangeable Share
provisions, the holder will be deemed to have exercised the optional Exchange
Right with respect to the unredeemed Series 1 Exchangeable Shares, and Veritas
DGC will be required to purchase such shares from the holder in the manner set
forth above.
 
     Automatic Exchange Right.  In the event of a Veritas DGC Liquidation Event
(as defined below), in order for the holders of the Series 1 Exchangeable Shares
to participate on a pro rata basis with the holders of a Veritas DGC Common
Stock, Veritas DGC will be required to acquire each outstanding Series 1
Exchangeable Share by exchanging one share of Veritas DGC Common Stock for each
such Series 1 Exchangeable Share, plus an additional amount equivalent to the
full amount of all declared and unpaid dividends on the Series 1 Exchangeable
Shares. Veritas DGC shall be entitled to liquidate some of the Veritas DGC
Common Stock that would otherwise be delivered to the particular holder in order
to fund any statutory withholding tax obligation. In this Joint Proxy Statement,
"Veritas DGC Liquidation Event" means (1) any determination by the Veritas DGC
board to institute voluntary liquidation, dissolution, or winding-up proceedings
with respect to Veritas DGC or to effect any other distribution of assets of
Veritas DGC among its stockholders for the purpose of winding up its affairs; or
(2) immediately upon the earlier of (A) receipt by Veritas DGC of notice of, and
(B) Veritas DGC becoming aware of any threatened or instituted claim, suit or
proceedings with respect to the involuntary liquidation, dissolution or
winding-up of Veritas DGC or to effect any other distribution of assets of
Veritas DGC among its stockholders for the purpose of winding-up its affairs.
 
DELIVERY OF VERITAS DGC COMMON STOCK
 
     Veritas DGC will ensure that all shares of Veritas DGC Common Stock to be
delivered by it under the Support Agreement or on the exercise of the Exchange
Rights under the Voting and Exchange Trust Agreement are duly registered,
qualified or approved under applicable Canadian and United States securities
laws, if required so that such shares may be freely traded by the holder thereof
(other than any restriction on transfer by reason of a holder being a "control
person" of Veritas DGC for purposes of Canadian law or an affiliate of Veritas
DGC for purposes of United States law). In addition, Veritas DGC will take all
actions necessary to cause all such shares of Veritas DGC Common Stock to be
listed or quoted for trading on all stock exchanges or quotation systems on
which outstanding shares of Veritas DGC Common Stock are then listed or quoted
for trading.
 
CALL RIGHTS
 
     The following description of the Retraction Call Right, Liquidation Call
Right and Redemption Call Right (all as defined below ) (collectively, the "Call
Rights") is qualified in its entirety by reference to the full text of the Plan
of Arrangement and the Series 1 Exchangeable Share provisions, which are
attached as Annex D. The Call Rights received by Veritas DGC in connection with
the consummation of the Combination Agreement shall be consideration for the
provision of the Ancillary Rights by Veritas DGC to the holders of the Enertec
Common Shares.
 
     In the circumstances described below, Veritas DGC will have certain
overriding rights to acquire Series 1 Exchangeable Shares from holders thereof
for one share of Veritas DGC Common Stock for each Series 1 Exchangeable Share
acquired, plus an amount equivalent to the full amount of all declared and
unpaid dividends on the Series 1 Exchangeable Shares. Different Canadian federal
income tax consequences to a holder of Series 1 Exchangeable Shares may arise
depending upon whether the Call Rights are exercised by Veritas DGC or
                                       48
<PAGE>   62
 
whether the relevant Series 1 Exchangeable Shares are redeemed by VESI pursuant
to the Series 1 Exchangeable Share provisions in the absence of the exercise of
Veritas DGC of the Call Rights. See "Canadian Federal Income Tax Considerations
to Enertec Shareholders."
 
     Retraction Call Right.  Pursuant to the Series 1 Exchangeable Share
provisions, a holder requesting VESI to redeem the Series 1 Exchangeable Shares
will be deemed to offer such shares to Veritas DGC, and Veritas DGC will have an
overriding right to acquire all but not less than all of the Series 1
Exchangeable Shares that the holder has requested VESI to redeem in exchange for
one share of Veritas DGC Common Stock for each Series 1 Exchangeable Share, plus
an additional amount equivalent to the full amount of all declared and unpaid
dividends thereon (the "Retraction Call Right").
 
     At the time of a retraction request by a holder of Series 1 Exchangeable
Shares, VESI will immediately notify Veritas DGC. Veritas DGC must then advise
VESI within two business days as to whether Veritas DGC will exercise the
Retraction Call Right. If Veritas DGC does not advise VESI within such two
business day period, VESI will notify the holder as soon as possible thereafter
that Veritas DGC will not exercise the Retraction Call Right. A holder may
revoke his or her retraction request, at any time prior to the close of business
on the business day preceding the retraction date, in which case the holder's
Series 1 Exchangeable Shares will neither be purchased by Veritas DGC nor
redeemed by VESI. If the holder does not revoke his or her retraction request,
on the retraction date the Series 1 Exchangeable Shares that the holder has
requested VESI to redeem will be acquired by Veritas DGC (assuming Veritas DGC
exercises its Retraction Call Right) or redeemed by VESI, as the case may be, in
each case for one share of Veritas DGC Common Stock for each Series 1
Exchangeable Share plus an additional amount equivalent to the full amount of
all declared and unpaid dividends on the Series 1 Exchangeable Shares. Veritas
DGC or VESI, as the case may be, shall be entitled to liquidate some of the
Veritas DGC Common Stock otherwise deliverable to the particular holder to fund
any statutory withholding tax obligation.
 
     Liquidation Call Right.  Pursuant to the Arrangement, Veritas DGC will be
granted an overriding right, in the event of and notwithstanding a proposed VESI
Insolvency Event, to acquire all but not less than all of the Series 1
Exchangeable Shares then outstanding in exchange for Veritas DGC Common Stock
and, upon the exercise by Veritas DGC of the Liquidation Call Right, the holders
thereof will be obligated to transfer such shares to Veritas DGC (the
"Liquidation Call Right"). The acquisition by Veritas DGC of all of the
outstanding Series 1 Exchangeable Shares upon the exercise of the Liquidation
Call Right will occur on the effective date of the voluntary or involuntary
liquidation, dissolution or winding-up of VESI. Veritas DGC shall be entitled to
liquidate some of the Veritas DGC Common Stock that would otherwise be
deliverable to the particular holder in order to fund any statutory withholding
tax obligation.
 
     Redemption Call Right.  Pursuant to the Arrangement, Veritas DGC will be
granted an overriding right, notwithstanding the proposed automatic redemption
of the Series 1 Exchangeable Shares by VESI pursuant to the Series 1
Exchangeable Share provisions, to acquire on an Automatic Redemption Date all
but not less than all of the Series 1 Exchangeable Shares then outstanding in
exchange for Veritas DGC Common Stock plus an additional amount equivalent to
the full amount of all declared and unpaid dividends on the Series 1
Exchangeable Shares and, upon the exercise by Veritas DGC of the Redemption Call
Right, the holders thereof will be obligated to transfer such shares to Veritas
DGC (the "Redemption Call Right"). Veritas DGC shall be entitled to liquidate
some of the Veritas DGC Common Stock that would otherwise be deliverable to the
particular holder in order to fund any statutory withholding tax obligation.
 
     Effect of Call Right Exercise.  If Veritas DGC exercises one or more of its
Call Rights, it will directly issue Veritas DGC Common Stock to holders of
Series 1 Exchangeable Shares and will become the holder of such Series 1
Exchangeable Shares. Veritas DGC will not be entitled to exercise any voting
rights attached to the Series 1 Exchangeable Shares it so acquires. If Veritas
DGC declines to exercise its Call Rights when applicable, it will be required,
pursuant to the Support Agreement, to issue Veritas DGC Common Stock to VESI
which will, in turn, transfer such stock to the holders of Series 1 Exchangeable
Shares in consideration for the return and cancellation of such Series 1
Exchangeable Shares. In the event Veritas DGC does not exercise its Call Rights
when applicable and instead delivers shares of Veritas DGC Common Stock to VESI
in accordance with the Support Agreement, there will be no differing financial,
tax (other than those tax consequences that are discussed
 
                                       49

in "Canadian Federal Income Tax Considerations to Enertec Shareholders," which
includes a discussion on deemed dividends and Part VI.1 Tax) or legal impact to
Veritas DGC or VESI; however, Veritas DGC anticipates that it will exercise its
Call Rights, when available, and currently foresees no circumstances under which
it would not exercise such Call Rights. In addition, Veritas DGC does not
anticipate any restriction or limitation on the number of Series 1 Exchangeable
Shares it would acquire upon exercise of Call Rights.

       CANADIAN FEDERAL INCOME TAX CONSIDERATIONS TO ENERTEC SHAREHOLDERS
 
INTRODUCTION
 
     Subject to the qualifications and assumptions contained herein, in the
opinion of Fraser Milner, Canadian counsel to Enertec, the following is a fair
and adequate summary of the principal Canadian federal income tax
considerations, as of the date of this Joint Proxy Statement generally
applicable to Enertec shareholders who at all relevant times, for purposes of
the Canadian Tax Act, hold their Enertec Common Shares and will hold their
Series 1 Exchangeable Shares and shares of Veritas DGC Common Stock as capital
property and deal at arm's length with, and are not affiliated with, Enertec or
Veritas DGC. This discussion does not apply to a holder with respect to whom
Veritas DGC is a foreign affiliate within the meaning of the Canadian Tax Act.
It is assumed that an Enertec shareholder who exchanges Enertec Common Shares
for Series 1 Exchangeable Shares receives no other consideration therefor
(except for cash in lieu of a fraction of a Series 1 Exchangeable Share).
 
     All Enertec shareholders should consult their own tax advisors as to
whether, as a matter of fact, they hold their Enertec Common Shares and will
hold their Series 1 Exchangeable Shares and shares of Veritas DGC Common Stock
as capital property for the purposes of the Canadian Tax Act. Certain provisions
of the Canadian Tax Act (the "mark-to-market rules") relating to financial
institutions (including certain financial institutions, registered securities
dealers and certain corporations controlled by one or more of the foregoing)
will preclude such financial institutions from treating their Enertec Common
Shares, Series 1 Exchangeable Shares and shares of Veritas DGC Common Stock as
capital property for purposes of the Canadian Tax Act. (The "Proposed
Amendments," as defined below, will expand the definition of financial
institution.) This discussion does not take into account the mark-to-market
rules, and Enertec shareholders that are financial institutions for the purposes
of these rules should consult their own tax advisors to determine the tax
consequences to them of the Arrangement.
 
     This discussion is based on the current provisions of the Canadian Tax Act
and the regulations thereunder, the current provisions of the Canada-United
States Income Tax Convention (the "Tax Treaty"), and counsel's understanding of
the current published administrative practices of Revenue Canada. This
discussion takes into account all specific proposals to amend the Canadian Tax
Act and the regulations thereunder that have been publicly announced by or on
behalf of the Minister of Finance (Canada) prior to the date hereof (the
"Proposed Amendments") and assumes that all such Proposed Amendments will be
enacted in their present form. No assurances can be given that the Proposed
Amendments will be enacted in the form proposed, if at all; however, the
Canadian federal income tax considerations generally applicable to a Enertec
shareholder with respect to the Arrangement will not be different in a material
adverse way if the Proposed Amendments are not enacted.
 
     Except for the foregoing, this discussion does not take into account or
anticipate any changes in law, whether by legislative, administrative or
judicial decision or action, nor does it take into account provincial,
territorial or foreign income tax legislation or considerations which may differ
from the Canadian federal income tax considerations described herein.
 
     THIS DISCUSSION IS OF A GENERAL NATURE ONLY. THEREFORE, ENERTEC
SHAREHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THEIR
PARTICULAR CIRCUMSTANCES. NO ADVANCE INCOME TAX RULING HAS BEEN OBTAINED FROM
REVENUE CANADA TO CONFIRM THE TAX CONSEQUENCES OF ANY OF THE TRANSACTIONS
DESCRIBED HEREIN.
 
     For purposes of the Canadian Tax Act, all amounts relating to the
acquisition, holding or disposition of shares of Veritas DGC Common Stock,
including dividends, adjusted cost base and proceeds of disposition, must be
converted into Canadian dollars based on the prevailing United States dollar
exchange rate at the time such amounts arise. In computing a shareholder's
liability for tax under the Canadian Tax Act, any cash amounts received by a
shareholder in U.S. dollars must be converted into the Canadian dollar
equivalent, and the amount of any non-share consideration received by a
shareholder must be expressed in Canadian dollars at the time such consideration
is received.
 
                                       51
<PAGE>   65
 
SHAREHOLDERS RESIDENT IN CANADA
 
     The following portion of this discussion is generally applicable to Enertec
shareholders who, for the purposes of the Canadian Tax Act and any applicable
income tax treaty or convention, are resident or deemed to be resident in Canada
at all relevant times. Certain of such persons to whom the Enertec Common Shares
might not constitute capital property may elect, in certain circumstances, to
have such property treated as capital property by making the irrevocable
election permitted by subsection 39(4) of the Canadian Tax Act.
 
    Disposition of Veritas DGC Consideration and Acquisition of Ancillary Rights
 
     Each of Veritas DGC and VESI is of the view, and has advised counsel, that
the Ancillary Rights have nominal value. On this basis, an Enertec shareholder
who receives Ancillary Rights in exchange for the Veritas DGC Consideration
should realize only a nominal gain at the time that any such consideration is
received from Veritas DGC. Similarly, the cost of the Ancillary Rights received
in connection with the disposition of the Veritas DGC Consideration will be
equal to their fair market value at the time of the exchange. Such
determinations of value are not binding on Revenue Canada and counsel can
express no opinion on matters of factual determination such as this.
 
     For these purposes, an Enertec shareholder will be required to determine
the fair market value of the Ancillary Rights on a reasonable basis.
 
    Exchange of Enertec Common Shares for Series 1 Exchangeable Shares Where No
    Election is Made under Section 85 of the Canadian Tax Act
 
     Based on the assumption that an Enertec shareholder who exchanges Enertec
Common Shares for Series 1 Exchangeable Shares receives no other consideration
therefor, in the opinion of counsel, the exchange of Enertec Common Shares for
Series 1 Exchangeable Shares will qualify as a tax-deferred share-for-share
exchange pursuant to section 85.1 of the Canadian Tax Act, as described below.
However, there is no direct authority addressing the proper treatment of the
Arrangement under the Canadian Tax Act. While counsel is of the view that it is
appropriate to make such assumption, if Revenue Canada were to successfully
challenge such assumption, Enertec shareholders would not be entitled to a
tax-deferred share-for-share exchange pursuant to section 85.1 of the Canadian
Tax Act. However, if an Enertec shareholder makes an election under section 85
of the Canadian Tax Act, section 85.1 will not be applicable and the Enertec
shareholder will be entitled to the tax deferral provided by section 85. Enertec
shareholders are urged to consult their own tax advisors to determine whether
they should make an election under section 85 of the Canadian Tax Act, as
described below, in order to provide greater certainty as to a tax-deferred
exchange.
 
     Pursuant to section 85.1 of the Canadian Tax Act, an Enertec shareholder
will not realize any immediate tax consequences as a result of exchanging
Enertec Common Shares for Series 1 Exchangeable Shares provided that such
Enertec shareholder does not make a joint election under section 85 of the
Canadian Tax Act in respect of such exchange as discussed below and does not, in
the Enertec shareholder's return of income for the taxation year in which such
exchange occurs, include in computing the Enertec shareholder's income, any
portion of the capital gain or capital loss, otherwise determined from such
exchange. Instead, the Enertec shareholder will be deemed (1) to have disposed
of that holder's Enertec Common Shares for proceeds of disposition equal to the
adjusted cost base to the holder immediately before such exchange, and (2) to
have acquired the Series 1 Exchangeable Shares at a cost equal to the deemed
proceeds of disposition of the holder's Enertec Common Shares. Such cost will
generally be averaged with the cost of other Series 1 Exchangeable Shares held
by such holder. Pursuant to Revenue Canada's current administrative practices,
an Enertec shareholder who receives cash not exceeding C$200 in lieu of a
fraction of a Series 1 Exchangeable Share, will have the option of recognizing
the capital gain or capital loss arising on the disposition of the fractional
share or alternatively of reducing the adjusted cost base of the Series 1
Exchangeable Shares acquired by the amount of cash so received.
 
     Where an Enertec shareholder exchanges Enertec Common Shares for Series 1
Exchangeable Shares and, in the Enertec shareholder's return of income for the
taxation year in which such exchange occurs, includes in computing income for
that year any portion of the capital gain or capital loss from such exchange,
section 85.1 the Canadian Tax Act will not apply. In such circumstances, the
Enertec shareholder will be considered to have
                                       52
<PAGE>   66
 
disposed of all of the holder's Enertec Common Shares so exchanged for proceeds
of disposition equal to the fair market value of the Series 1 Exchangeable
Shares received on such exchange and to have acquired the Series 1 Exchangeable
Shares at a cost equal to the fair market value, unless the Enertec shareholder
elects under section 85 of the Canadian Tax Act, as further described below.
Such cost will generally be averaged with the cost of other Series 1
Exchangeable Shares previously held by the Enertec shareholder. An Enertec
shareholder who so chooses to realize a capital gain or capital loss on the
exchange of the holder's Enertec Common Shares will realize a capital gain (or a
capital loss) on such exchange to the extent that the holder's proceeds of
disposition, net of any reasonable costs of disposition, exceed (or are less
than) the adjusted cost base of that holder's Enertec Common Shares immediately
before such exchange.
 
     The consequences to an Enertec shareholder of realizing a capital gain or
capital loss are as described below under "Taxation of Capital Gains and Capital
Losses."
 
     Exchange of Enertec Common Shares for Series 1 Exchangeable Shares Where
     Election is Made under Section 85 of the Canadian Tax Act
 
     An Enertec shareholder who disposes of Enertec Common Shares to VESI and
who receives Series 1 Exchangeable Shares may obtain a full or partial tax
deferral by entering into a joint tax election with VESI and filing with Revenue
Canada (and where applicable a provincial tax authority) a joint tax election
under subsection 85(1) of the Canadian Tax Act or, in the case of an Enertec
shareholder that is a partnership, under subsection 85(2) of the Canadian Tax
Act, (and the corresponding provisions of any applicable provincial tax
legislation) in respect of such Enertec Common Shares and specifying therein a
transfer price (the "Elected Transfer Price") within the limits described below.
 
     The joint tax election must specify the Elected Transfer Price in respect
of the Enertec Common Shares transferred to VESI. The Elected Transfer Price may
not:
 
     -  be less than any cash received by the Enertec shareholder;
 
     -  be less than the lesser of the Enertec shareholder's adjusted cost base
        of those Enertec Common Shares at the time of disposition and the fair
        market value of those Enertec Common Shares at that time; and
 
     -  exceed the fair market value of those Enertec Common Shares at the time
        of disposition.
 
     Elected Transfer Prices, which do not otherwise comply with the foregoing
limitations, will be automatically adjusted under the Canadian Tax Act so that
they are in compliance.
 
     Where an Enertec shareholder makes a joint tax election in respect of the
disposition of such holder's Enertec Common Shares to VESI in the form
prescribed under the Canadian Tax Act and specifies therein an Elected Transfer
Price within the limits set out in the Canadian Tax Act, and the joint tax
election is filed with Revenue Canada within the time prescribed in the Canadian
Tax Act, the Canadian federal income tax consequences are as follows:
 
     -  Such Enertec Common Shares will be deemed to have been disposed of for
        proceeds of disposition equal to the Elected Transfer Price. If the
        proceeds of disposition in respect of such Enertec Common Shares are
        equal to the aggregate of the Enertec shareholder's adjusted cost base
        of those Enertec Common Shares (determined immediately before the
        disposition) and any reasonable costs of disposition, no capital gain or
        capital loss will be realized by the Enertec shareholder. Subject to the
        limitations set out in subsections 85(1) and (2) of the Canadian Tax
        Act, to the extent that the proceeds of disposition in respect of the
        Enertec Common Shares exceed (or are less than) the aggregate of the
        adjusted cost base thereof and any reasonable costs of disposition, the
        Enertec shareholder will realize a capital gain (or a capital loss). The
        taxation of capital gains and capital losses is described below.
 
     -  The cost to a shareholder of the Series 1 Exchangeable Shares received
        upon the disposition of the Enertec Common Shares to VESI will be equal
        to the Elected Transfer Price in respect of those Enertec Common Shares,
        less any cash consideration received.
 
                                       53
<PAGE>   67
 
     Consequently, notwithstanding any election, if the cash consideration
received by an Enertec shareholder exceeds the adjusted cost base of his Enertec
Common Shares and any reasonable costs of disposition, the holder will realize a
capital gain at least equal to such excess. The taxation of capital gains and
capital losses is described below.
 
     The election forms may be obtained from Revenue Canada and (if applicable)
the appropriate provincial election forms may be obtained from the relevant
provincial income tax authorities.
 
     In order to make a joint tax election, two copies of a duly completed joint
election form (Revenue Canada form T2057) together with any required supporting
schedules must be signed and forwarded (together with any corresponding
provincial election forms) by the Enertec shareholder to VESI within 90 days
following the Effective Date. Thereafter subject to the election forms complying
with the provisions of the Canadian Tax Act, the forms will be signed by VESI
and returned to the Enertec shareholder for filing with Revenue Canada. VESI
will not execute any tax election received by VESI after 90 days following the
Effective Date.
 
     Where Enertec Common Shares are held in joint ownership and two or more of
the co-owners wish to make an election, then one of the co-owners designated for
such purpose should file (in duplicate) the designation and the Revenue Canada
form T2057 (and, where applicable, the corresponding provincial election forms)
for each co-owner along with a list of all co-owners electing, which list should
contain the address and social insurance number or tax account number of each
co-owner. Where the Enertec Common Shares are held as partnership property, a
partner designated by the partnership must file one Revenue Canada form T2058
(in duplicate) on behalf of all members of the partnership (and, where
applicable, the corresponding provincial election form, in duplicate, with the
provincial taxation authorities). Such Revenue Canada form T2058 (and provincial
form, if applicable) must be accompanied by a list containing the name and
social insurance number or account number of each partner and must be signed by
each partner or be accompanied by a copy of the document authorizing the
designated partner to complete, execute and file the form on behalf of the other
partners.
 
     VESI will make a joint tax election under subsection 85(1) or (2) of the
Canadian Tax Act and the corresponding provisions of any applicable provincial
tax legislation only with an Enertec shareholder, and at the amount(s)
determined by the Enertec shareholder subject to the limitations set out in
subsections 85(1) and (2) of the Canadian Tax Act and any applicable provincial
tax statute. VESI agrees only to execute any joint tax election and to forward
such tax election by mail (within 180 days following the Effective Date) to the
Enertec shareholder for filing with Revenue Canada and any applicable provincial
tax authorities. With the exception of execution of the election by VESI,
compliance with the requirements to ensure the validity of a joint tax election
will be the sole responsibility of the Enertec shareholder making the election.
VESI has advised counsel that it will not be responsible for the payment of any
late filing penalty that does not result from a failure on the part of VESI and
will not be responsible or liable for taxes, interest, penalties, damages or
expenses resulting from the failure by anyone to properly complete any joint tax
election form or to properly file such form within the time prescribed and in
the form prescribed under the Canadian Tax Act or the corresponding provisions
of any applicable provincial legislation.
 
     In order for Revenue Canada to accept the joint tax election without a late
filing penalty being paid by an Enertec shareholder, the joint tax election,
duly completed and executed by both the Enertec shareholder and VESI, must be
received by Revenue Canada on or before the day that is the earlier of the days
on or before which either VESI or the Enertec shareholder is required to file an
income tax return for the taxation year in which the disposition occurs. VESI
has advised counsel that its current taxation year is scheduled to end on July
31, 1999. VESI will be required to file an income tax return for the current
taxation year on or before January 31, 2000. In general, the joint tax elections
of Enertec shareholders who are individuals (other than trusts) must be filed by
April 30, 2000. HOWEVER, REGARDLESS OF SUCH DEADLINES, THE COMPLETED JOINT
ELECTION FORMS OF ENERTEC SHAREHOLDERS MUST BE RECEIVED BY VESI NO LATER THAN 90
DAYS FOLLOWING THE EFFECTIVE DATE. CERTAIN ENERTEC SHAREHOLDERS MAY BE REQUIRED
TO FORWARD THEIR COMPLETED JOINT ELECTION FORMS TO VESI BEFORE THAT DATE TO
AVOID LATE FILING PENALTIES. IF, FOR WHATEVER REASON, THE CURRENT TAXATION YEAR
OF VESI WERE TO TERMINATE BEFORE JULY 31, 1999, THE JOINT TAX ELECTIONS MIGHT
HAVE TO BE FILED EARLIER TO AVOID LATE FILING PENALTIES. IN SUCH EVENT, VESI HAS
AGREED TO NOTIFY FORTHWITH, THROUGH THE TRUSTEE, EVERY ENERTEC SHAREHOLDER WHO
RECEIVED SERIES 1 EXCHANGEABLE SHARES ON THE ARRANGEMENT OF SUCH CHANGE. ENERTEC
SHAREHOLDERS ARE
 
                                       54
<PAGE>   68
 
URGED TO CONSULT THEIR OWN ADVISORS AS SOON AS POSSIBLE REGARDING THE DEADLINES
APPROPRIATE TO THEIR CIRCUMSTANCES. ANY ENERTEC SHAREHOLDER WHO DOES NOT ENSURE
THAT VESI HAS RECEIVED A DULY COMPLETED JOINT ELECTION FORM WITHIN 90 DAYS FROM
THE EFFECTIVE DATE, WILL NOT BE ABLE TO BENEFIT FROM THE PROVISION OF SECTION 85
OF THE CANADIAN TAX ACT. ACCORDINGLY, ALL ENERTEC SHAREHOLDERS WHO WISH TO ENTER
INTO A JOINT ELECTION WITH VESI SHOULD GIVE THEIR IMMEDIATE ATTENTION TO THIS
MATTER.
 
     Enertec shareholders who wish to make a joint tax election are referred for
further information to Information Circular 76-19R3 and Interpretation Bulletin
IT-291R2 issued by Revenue Canada.
 
     ENERTEC SHAREHOLDERS WISHING TO COMPLETE A FEDERAL OR, IF APPLICABLE, A
PROVINCIAL TAX ELECTION SHOULD CONSULT THEIR OWN TAX ADVISORS. THE COMMENTS
HEREIN WITH RESPECT TO SUCH JOINT TAX ELECTIONS ARE PROVIDED FOR GENERAL
ASSISTANCE ONLY. THE LAW IN THIS AREA IS COMPLEX AND CONTAINS NUMEROUS TECHNICAL
REQUIREMENTS. COMPLIANCE WITH SUCH REQUIREMENTS TO ENSURE THE VALIDITY OF THE
JOINT TAX ELECTION WILL BE THE SOLE RESPONSIBILITY OF THE ENERTEC SHAREHOLDER.
 
     Taxation of Capital Gains and Capital Losses
 
     Three-quarters of any capital gain ("taxable capital gain") must be
included in a shareholder's income for the year of disposition. Three-quarters
of any capital loss ("allowable capital loss") generally must be deducted by the
holder from taxable capital gains for the year of disposition. Any allowable
capital losses in excess of taxable capital gains for the year of disposition
generally may be carried back up to three taxation years or carried forward
indefinitely and deducted against net taxable capital gains (taxable capital
gains less allowable capital losses) in such other years to the extent and under
the circumstances described in the Canadian Tax Act.
 
     Capital gains realized by an individual or trust, other than other certain
specified trusts, may give rise to alternative minimum tax under the Canadian
Tax Act.
 
     A shareholder that is throughout the relevant taxation year a
"Canadian-controlled private corporation" (as defined in the Canadian Tax Act)
may be liable to pay an additional refundable tax of 6 2/3% on its "aggregate
investment income" for the year which will include an amount in respect of
taxable capital gains.
 
     If the holder of an Enertec Common Share or a Series 1 Exchangeable Share
is a corporation, the amount of any capital loss arising from a disposition or
deemed disposition of such share may be reduced by the amount of dividends
received or deemed to have been received by it on such share to the extent and
under circumstances prescribed by the Canadian Tax Act. Similar rules may apply
where a corporation is a member of a partnership or a beneficiary of a trust
that owns Enertec Common Shares or Series 1 Exchangeable Shares or where a trust
or partnership of which a corporation is a beneficiary or a member is a member
of a partnership or a beneficiary of a trust that owns Enertec Common Shares or
Series 1 Exchangeable Shares. Shareholders to whom these rules may be relevant
should consult their own tax advisors.
 
     Dividends on Series 1 Exchangeable Shares
 
     In the case of a shareholder who is an individual, dividends received or
deemed to be received on the Series 1 Exchangeable Shares will be included in
computing the shareholder's income, and will be subject to the gross-up and
dividend tax credit rules normally applicable to taxable dividends received from
taxable Canadian corporations.
 
     In the case of a shareholder that is a corporation other than a "specified
financial institution" (as defined in the Canadian Tax Act), dividends received
or deemed to be received on the Series 1 Exchangeable Shares normally will be
included in the corporation's income and deductible in computing its taxable
income.
 
     A shareholder that is a "private corporation" (as defined in the Canadian
Tax Act) or any other corporation resident in Canada and controlled or deemed to
be controlled by or for the benefit of an individual or a related group of
individuals may be liable under Part IV of the Canadian Tax Act to pay a
refundable tax of 33 1/3% of dividends received or deemed to be received on the
Series 1 Exchangeable Shares to the extent that such dividends are deductible in
computing the shareholder's taxable income.
 
                                       55
<PAGE>   69
 
     The Series 1 Exchangeable Shares will be "term preferred shares" as defined
in the Canadian Tax Act. Consequently, in the case of a shareholder that is a
specified financial institution, such a dividend will be deductible in computing
its taxable income only if:
 
     (i)    the specified financial institution did not acquire the Series 1
            Exchangeable Shares in the ordinary course of the business carried
            on by such institution; or
 
     (ii)   in any case, at the time the dividend is received by the specified
            financial institution, the Series 1 Exchangeable Shares are listed
            on a prescribed stock exchange in Canada (which currently includes
            the TSE) and the specified financial institution, either alone or
            together with persons with whom it does not deal at arm's length,
            does not receive (or is not deemed to receive) dividends in respect
            of more than 10% of the issued and outstanding Series 1 Exchangeable
            Shares.
 
     In addition, to the extent that a deemed dividend arises on the redemption
of the Series 1 Exchangeable Shares by VESI, a portion of the dividend may not
be subject to the denial of dividend deduction applicable in respect of term
preferred shares in accordance with the exceptions outlined above. Specified
financial institutions should consult their own tax advisors.
 
     A shareholder that is throughout the relevant taxation year a
"Canadian-controlled private corporation" (as defined in the Canadian Tax Act)
may be liable to pay an additional refundable tax of 6 2/3% on its "aggregate
investment income" for the year which will include dividends or deemed dividends
that are not deductible in computing taxable income.
 
     The Series 1 Exchangeable Shares will be "taxable preferred shares" and
"short-term preferred shares" for purpose of the Canadian Tax Act. Accordingly,
VESI will be subject to a 66 2/3% tax under Part VI.I of the Canadian Tax Act on
dividends (other than "excluded dividends" as defined in the Canadian Tax Act)
paid or deemed to be paid on the Series 1 Exchangeable Shares and will be
entitled to deduct an amount equal to 9/4 of the tax so payable in computing its
taxable income for purposes of the Canadian Tax Act. Dividends received or
deemed to be received on the Series 1 Exchangeable Shares will not be subject to
the 10% tax under Part IV.1 of the Canadian Tax Act applicable to certain
corporations.
 
     Redemption of Series 1 Exchangeable Shares
 
     On the redemption (including a retraction) of a Series 1 Exchangeable Share
by VESI, the holder of a Series 1 Exchangeable Share will be deemed to have
received a dividend equal to the amount, if any, by which the redemption
proceeds exceed the paid-up capital at the time of the Series 1 Exchangeable
Share so redeemed. For these purposes, the redemption proceeds will be the fair
market value at the time of the redemption, of the shares of Veritas DGC Common
Stock received from VESI plus the amount, if any, of all accrued but unpaid
dividends on the Series 1 Exchangeable Shares paid on the redemption. The amount
of such deemed dividend generally will be subject to the same tax treatment
accorded to dividends on the Series 1 Exchangeable Shares as described above. On
the redemption, the holder of a Series 1 Exchangeable Share will also be
considered to have disposed of the Series 1 Exchangeable Share, but the amount
of such deemed dividend will be excluded in computing the shareholder's proceeds
of disposition for purposes of computing any capital gain or capital loss
arising on the disposition. In the case of a shareholder that is a corporation,
in some circumstances, the amount of any such deemed dividend may be treated as
proceeds of disposition and not as a dividend. The taxation of capital gains and
capital losses is described above.
 
     Exchange of Series 1 Exchangeable Shares with Veritas DGC
 
     On the exchange of a Series 1 Exchangeable Shares with Veritas DGC for
shares of Veritas DGC Common Stock, the holder will generally realize a capital
gain (or a capital loss) equal to the amount by which the proceeds of
disposition of the Series 1 Exchangeable Shares, net of any reasonable costs of
disposition, exceed (or are less than) the adjusted cost base to the holder of
the Series 1 Exchangeable Shares immediately before the exchange. For these
purposes, the proceeds of disposition will be the fair market value at the time
of exchange of the shares of Veritas DGC Common Stock plus any other amount
received by the holder from Veritas DGC as part of the exchange consideration.
The taxation of capital gains and capital losses is described above.
 
                                       56

     BECAUSE OF THE EXISTENCE OF THE RETRACTION CALL RIGHT, A HOLDER EXERCISING
THE RIGHT OF RETRACTION IN RESPECT OF SERIES 1 EXCHANGEABLE SHARES CANNOT
CONTROL WHETHER SUCH HOLDER WILL RECEIVE SHARES OF VERITAS DGC COMMON STOCK BY
WAY OF REDEMPTION OF THE SERIES 1 EXCHANGEABLE SHARES BY VESI OR BY WAY OF
PURCHASE OF THE SERIES 1 EXCHANGEABLE SHARES BY VERITAS DGC. AS DESCRIBED ABOVE,
THE CANADIAN FEDERAL INCOME TAX CONSEQUENCES OF A REDEMPTION DIFFER FROM THOSE
OF A PURCHASE.
 
     Dividends on Veritas DGC Common Stock
 
     Dividends on shares of Veritas DGC Common Stock will be included in the
recipient's income for the purposes of the Canadian Tax Act. Such dividends
received by an individual shareholder will not be subject to the gross-up and
dividend tax credit rules in the Canadian Tax Act. A shareholder that is a
corporation will include such dividends in computing its income and generally
will not be entitled to deduct the amount of such dividends in computing its
taxable income. A shareholder that is throughout the relevant taxation year a
"Canadian-controlled private corporation" (as defined in the Canadian Tax Act)
may be liable to pay an additional refundable tax of 6 2/3% on its "aggregate
investment income" for the year which will include such dividends. United States
non-resident withholding tax on such dividends will be eligible for foreign tax
credit or deduction treatment, where applicable, under the Canadian Tax Act. See
"United States Federal Income Tax Considerations to Enertec Shareholders --
Shareholders Not Resident in or Citizens of the United States."
 
     Disposition of Shares of Veritas DGC Common Stock
 
     The cost of a share of Veritas DGC Common Stock received on a retraction,
redemption or exchange of a Series 1 Exchangeable Share will be equal to the
fair market value of such share at the time of such event. The adjusted cost
base to a holder of shares of Veritas DGC Common Stock acquired on a retraction,
redemption or exchange of a Series 1 Exchangeable Share will be determined by
averaging the cost of such share with the adjusted cost base of all other shares
of Veritas DGC Common Stock held by such holder as capital property immediately
before the retraction, redemption or exchange, as the case may be. A disposition
or deemed disposition of a share of Veritas DGC Common Stock by a holder will
generally result in a capital gain (or a capital loss) equal to the amount by
which the proceeds of disposition, net of any reasonable costs of disposition,
exceed (or are less than) the adjusted cost base to the holder of such share
immediately before the disposition. The taxation of capital gains and capital
losses is described above.
 
     Foreign Property Information Reporting
 
     A holder of shares of Veritas DGC Common Stock, who is a "specified
Canadian entity" for a taxation year or fiscal period and whose total cost
amount of "specified foreign property", including such shares, at any time in
the year or fiscal period exceeds C$100,000 will be required to file an
information return for the year or period disclosing prescribed information,
including the shareholder's cost amount, any dividends received in the year, and
any gains or losses realized in the year, in respect of such property. With some
exceptions, a taxpayer resident in Canada in the year will be a specified
Canadian entity. A holder of Veritas DGC Common Stock should consult its own
advisors about whether it must comply with these rules.
 
     Dissenting Shareholders
 
     Enertec shareholders are permitted to dissent from the Arrangement in the
manner set out in section 184 of the ABCA. A dissenting Enertec shareholder will
be entitled, in the event the Arrangement becomes effective, to be paid by
Enertec the fair value of the Enertec Common Shares held by such holder
determined as of the appropriate date. See "Dissenting Shareholders' and
Optionholders' Rights." Such shareholder will be considered to have realized a
deemed dividend to the extent that the proceeds of disposition exceed the
paid-up capital and a capital gain (or a capital loss) to the extent that the
proceeds of disposition less the deemed dividend exceed (or are less than) the
adjusted cost base to the holder immediately before payment of the fair value of
the Enertec Common Shares. Additional income tax considerations may be relevant
to dissenting Enertec shareholders who fail to perfect or withdraw their claims
pursuant to the right of dissent. Dissenting Enertec shareholders should consult
their own tax advisors.

SHAREHOLDERS NOT RESIDENT IN CANADA
 
     The following portion of the discussion is applicable to Enertec
shareholders who, for purposes of the Canadian Tax Act and any applicable tax
treaty or convention, have not been and will not be resident or deemed to be
resident in Canada at any time while they have held Enertec Common Shares or
will hold Series 1 Exchangeable Shares or shares of Veritas DGC Common Stock
and, except as specifically discussed below, to whom such shares are not
"taxable Canadian property" (as defined in the Canadian Tax Act and the Proposed
Amendments) and, in the case of a non-resident of Canada who carries on an
insurance business in Canada and elsewhere, such shares are not "designated
insurance property" as defined in the Canadian Tax Act.
 
     Generally, Enertec Common Shares and Series 1 Exchangeable Shares will not
be taxable Canadian property at a particular time provided that such shares are
listed on a prescribed stock exchange (which exchanges currently include the
TSE), the holder does not use or hold, and is not deemed to use or hold, the
Enertec Common Shares or the Series 1 Exchangeable Shares in connection with
carrying on a business in Canada and the holder, persons with whom such holder
does not deal at arm's length, or the holder and such persons, has not owned (or
had under option) 25% or more of the issued shares of any class or series of the
capital stock of Enertec or VESI at any time within five years preceding the
particular time. The shares of Veritas DGC will not be taxable Canadian property
at a particular time provided that the holder does not use or hold, and is not
deemed to use or hold, the shares of Veritas DGC Common Stock in connection with
carrying on a business in Canada. In the case of VESI, even if the holder
exceeds the 25% threshold referred to above with respect to the Series 1
Exchangeable Shares, such shares may not be taxable Canadian property. At the
time of disposition such holder should consult its own tax advisors to determine
whether the Series 1 Exchangeable Shares constitute taxable Canadian property at
that time. The TSE has conditionally approved the listing of the Series 1
Exchangeable Shares. See "The Transaction -- Stock Exchange Listing."
 
     A holder of Enertec Common Shares that are not taxable Canadian property
will not be subject to tax under the Canadian Tax Act on the exchange of Enertec
Common Shares for Series 1 Exchangeable Shares. Similarly, provided the Series 1
Exchangeable Shares or shares of Veritas DGC Common Stock are not taxable
Canadian property to the holder, the holder will not be subject to tax under the
Canadian Tax Act on the exchange of a Series 1 Exchangeable Share for shares of
Veritas DGC Common Stock (except to the extent the exchange gives rise to a
deemed dividend discussed below), or on the sale or other disposition of a
Series 1 Exchangeable Share or share of Veritas DGC Common Stock.
 
     In the event that the Enertec Common Shares constitute taxable Canadian
property to a particular non-resident holder thereof, the exchange of Enertec
Common Shares for Series 1 Exchangeable Shares should qualify as a tax-deferred
share-for-share exchange as described above under "-- Shareholders Resident in
Canada -- Exchange of Enertec Common Shares for Series 1 Exchangeable Shares
Where No Election is Made under Section 85 of the Canadian Tax Act." However,
Enertec shareholders are urged to consult their own tax advisors to determine
whether they should make an election under section 85 of the Canadian Tax Act in
order to provide greater certainty in this regard. Even though the exchange of
Enertec Common Shares for Series 1 Exchangeable Shares may be subject to tax
under the Canadian Tax Act, this exchange may be exempt from Canadian tax by
virtue of an applicable tax treaty or convention. Where a capital gain arising
from the disposition of the Enertec Common Shares is not exempt from Canadian
tax by virtue of an applicable income tax treaty or convention, the non-resident
shareholder may choose to make an election pursuant to subsection 85(1) or (2)
of the Canadian Tax Act (or the corresponding provisions of any applicable
provincial tax legislation) in order to defer the recognition of the capital
gain as described above under "-- Shareholders Resident in Canada -- Exchange of
Enertec Common Shares for Series 1 Exchangeable Shares or Cash and Series 1
Exchangeable Shares Where an Election Is Made under Section 85 of the Canadian
Tax Act." REGARDLESS OF WHETHER AN ELECTION IS MADE, THE SERIES 1 EXCHANGEABLE
SHARES RECEIVED IN EXCHANGE FOR ENERTEC COMMON SHARES WILL BE DEEMED TO BE
TAXABLE CANADIAN PROPERTY TO SUCH HOLDER.
 
     Dividends paid or deemed to be paid on the Series 1 Exchangeable Shares are
subject to non-resident withholding tax under the Canadian Tax Act at the rate
of 25%, although such rate may be reduced under the provisions of an applicable
income tax treaty or convention. For example, under the Tax Treaty, the rate is
 
                                       58
<PAGE>   72
 
generally reduced to 15% in respect of dividends paid to a person who is the
beneficial owner thereof and who is resident in the United States for purposes
of the Tax Treaty.
 
     A HOLDER WHOSE SERIES 1 EXCHANGEABLE SHARES ARE REDEEMED BY VESI (EITHER
UNDER VESI'S REDEMPTION RIGHT OR PURSUANT TO THE HOLDER'S RETRACTION RIGHTS)
WILL BE DEEMED TO RECEIVE A DIVIDEND AS DESCRIBED ABOVE UNDER "-- SHAREHOLDERS
RESIDENT IN CANADA -- REDEMPTION OF SERIES 1 EXCHANGEABLE SHARES." ANY SUCH
DEEMED DIVIDEND WILL BE SUBJECT TO WITHHOLDING TAX AS DESCRIBED IN THE PRECEDING
PARAGRAPHS. HOLDERS OF SERIES 1 EXCHANGEABLE SHARES CANNOT CONTROL WHETHER THEY
WILL REALIZE A DEEMED DIVIDEND OR PROCEEDS OF DISPOSITION ON AN EXCHANGE OF THE
SERIES 1 EXCHANGEABLE SHARES FOR SHARES OF VERITAS DGC COMMON STOCK.
 
     Enertec shareholders are permitted to dissent from the Arrangement in the
manner set out in section 184 of the ABCA. A dissenting Enertec shareholder will
be entitled, in the event the Arrangement becomes effective, to be paid by
Enertec the fair value of the Enertec Common Shares held by such holder
determined as of the appropriate date. See "Dissenting Shareholders' and
Optionholders' Rights". Such shareholder will be considered to have realized a
deemed dividend and capital gain (or a capital loss) based on redemption
proceeds equal to such fair value, computed generally as described above in the
case of a redemption (including a retraction) of a Series 1 Exchangeable Share
by VESI for a share of Veritas DGC Common Stock under "-- Shareholders Resident
in Canada -- Redemption of Series 1 Exchangeable Shares." Deemed dividends will
be subject to withholding tax as described above. Any capital gain realized by a
dissenting Enertec shareholder would not be taxed under the Canadian Tax Act if
the Enertec Common Shares in respect of which the right of dissent is exercised
were not taxable Canadian property, as described above. Additional income tax
considerations may be relevant to dissenting Enertec shareholders who fail to
perfect or withdraw their claims pursuant to the right of dissent. Dissenting
Enertec shareholders should consult their own tax advisors.

      CANADIAN FEDERAL INCOME TAX CONSIDERATIONS TO ENERTEC OPTIONHOLDERS
 
     Subject to the qualifications and assumptions contained herein, in the
opinion of Fraser Milner, Canadian counsel to Enertec, the following is a fair
and adequate summary of the principal Canadian federal income tax
considerations, as of the date of this Joint Proxy Statement generally
applicable to the holders of Enertec Options who at all relevant times, for
purposes of the Canadian Tax Act and any applicable income tax treaty or
convention, are resident or deemed to be resident in Canada, who are current or
former employees, officers and directors of Enertec and who received the Enertec
options in respect of, in the course of, or by virtue of their positions as
employees, officers or directors of Enertec.
 
     This discussion is based on the current provisions of the Canadian Tax Act
and the regulations thereunder and counsel's understanding of the current
published administrative practices of Revenue Canada.
 
     This discussion does not take into account or anticipate any changes in
law, whether by legislative, administrative or judicial decision or action, nor
does it take into account provincial, territorial or foreign income tax
legislation or considerations which may differ from the Canadian federal income
tax considerations described herein.
 
     THIS DISCUSSION IS OF A GENERAL NATURE ONLY. THEREFORE, ENERTEC
OPTIONHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THEIR
PARTICULAR CIRCUMSTANCES. NO ADVANCE INCOME TAX RULING HAS BEEN OBTAINED FROM
REVENUE CANADA TO CONFIRM THE TAX CONSEQUENCES OF ANY OF THE TRANSACTIONS
DESCRIBED HEREIN.
 
EXCHANGE OF ENERTEC OPTIONS FOR OPTIONS TO PURCHASE SHARES OF VERITAS DGC COMMON
STOCK
 
     The holders of the Enertec Options will not realize any immediate tax
consequences as a result of exchanging the Enertec Options for options to
purchase shares of Veritas DGC Common Stock. Instead, for the purposes of the
Canadian Tax Act, (a) the Enertec optionholder will be deemed not to have
disposed of his Enertec Options and not to have acquired the Veritas DGC
Options, (b) the Veritas DGC Options will be deemed to be the same as, and a
continuation of, the Enertec Options, and (c) Veritas DGC will be deemed to be
the same corporation as Enertec for the purposes hereof.

    UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS TO ENERTEC SHAREHOLDERS
 
     In the opinion of Mayor, Day, Caldwell & Keeton LLP, United States counsel
to Enertec, the following is a summary of the material United States federal
income tax considerations generally applicable to Enertec shareholders that are
"United States holders" as defined below and that hold Enertec Common Shares as
capital assets, arising from and relating to the Arrangement, including the
receipt and ownership of Series 1 Exchangeable Shares and Veritas DGC Common
Stock. For purposes of this summary, "United States holders" are United States
citizens or residents (including certain former citizens and residents),
corporations or partnerships organized under the laws of the United States or
any state thereof, any estate subject to United States federal income tax on its
income regardless of source, and any trust if a United States court is able to
exercise primary supervision over the administration of the trust and one or
more United States persons have authority to control all substantial decisions
of the trust.
 
     This summary is based on United States federal income tax law in effect as
of the date hereof. No statutory, judicial, or administrative authority exists
which directly addresses certain of the United States federal income tax
consequences of the issuance and ownership of instruments and rights comparable
to the Series 1 Exchangeable Shares and the related rights. Consequently, some
aspects of the United States federal income tax treatment of the Arrangement,
including the receipt and ownership of Series 1 Exchangeable Shares and the
exchange of Series 1 Exchangeable Shares for shares of Veritas DGC Common Stock,
are not certain. No advance income tax ruling has been sought or obtained from
the United States Internal Revenue Service regarding the tax consequences of any
of the transactions described herein.
 
     This summary does not address aspects of United States taxation other than
United States federal income taxation, nor does it address all aspects of United
States federal income taxation that may be applicable to particular United
States holders, including, without limitation, holders of Enertec Common Shares
acquired as a result of the exercise of employee stock options. In addition,
this summary does not address (1) the United States state or local tax
consequences or (2) the foreign tax consequences of the Arrangement.
 
     UNITED STATES HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT
TO THE UNITED STATES FEDERAL, STATE, AND LOCAL TAX CONSEQUENCES AND THE FOREIGN
TAX CONSEQUENCES OF THE ARRANGEMENT, INCLUDING THE RECEIPT AND OWNERSHIP OF
SERIES 1 EXCHANGEABLE SHARES AND THE RELATED RIGHTS.
 
     Tax Treatment of the Arrangement.  It is anticipated that a United States
holder that receives Series 1 Exchangeable Shares and the related rights in
exchange for Enertec Common Shares in the Arrangement generally will recognize
gain or loss on the receipt of the Series 1 Exchangeable Shares and the related
rights. Such gain or loss will be equal to the difference between the fair
market value of the shares of Series 1 Exchangeable Shares and the related
rights at the time of the exchange and the United States holder's tax basis in
the Enertec Common Shares exchanged therefor. The gain or loss will be capital
gain or loss. Capital gain or loss will be long-term capital gain or loss if the
Enertec Common Shares have been held for more than one year at the time of the
exchange. The United States holder will take as such holder's tax basis in the
Series 1 Exchangeable Shares and the related rights the fair market value of the
shares of Series 1 Exchangeable Shares and the related rights received by the
United States holder in the Arrangement, and such holder's holding period will
begin on the day after the United States holder received the Series 1
Exchangeable Shares and the related rights.
 
     For United States federal income tax purposes, gain realized on the
exchange of Enertec Common Shares for Series 1 Exchangeable Shares generally
will be treated as United States source gain, except that, under the terms of
the Tax Treaty, such gain may be treated as sourced in Canada. Any Canadian tax
imposed on the exchange generally will be available as a credit against United
States federal income taxes, subject to applicable limitations. A United States
holder that is ineligible for a foreign tax credit with respect to any Canadian
tax paid may be entitled to a deduction therefor in computing United States
taxable income.
 
     Exchange of Series 1 Exchangeable Shares.  It is anticipated that a United
States holder that exercises such holder's rights to exchange the Series 1
Exchangeable Shares and the related rights for shares of Veritas DGC Common
Stock generally will recognize gain or loss on the receipt of the shares of
Veritas DGC Common Stock in exchange for such Series 1 Exchangeable Shares and
the related rights. Such gain or loss will be equal to the
 
                                       61
<PAGE>   75
 
difference between the fair market value of the shares of Veritas DGC Common
Stock at the time of the exchange and the United States holder's tax bases in
the Series 1 Exchangeable Shares and the related rights exchanged therefor. The
gain or loss will be capital gain or loss, except that, with respect to any
declared but unpaid dividends on the Series 1 Exchangeable Shares, ordinary
income may be recognized by the holder thereof. Capital gain or loss will be
long-term capital gain or loss if the Series 1 Exchangeable Shares have been
held as capital assets for more than one year at the time of the exchange. The
United States holder will take as such holder's tax basis in the shares of
Veritas DGC Common Stock the fair market value of the shares of Veritas DGC
Common Stock received by the United States holder in the exchange, and such
holder's holding period will begin on the day after the United States holder
received the shares of Veritas DGC Common Stock.
 
     For United States federal income tax purposes, gain realized on the
exchange of Series 1 Exchangeable Shares for shares of Veritas DGC Common Stock
generally will be treated as United States source gain, except that, under the
terms of the Tax Treaty, such gain may be treated as sourced in Canada. Any
Canadian tax imposed on the exchange generally will be available as a credit
against United States federal income taxes, subject to applicable limitations. A
United States holder that is ineligible for a foreign tax credit with respect to
any Canadian tax paid may be entitled to a deduction therefor in computing
United States taxable income.
 
     Distributions on the Series 1 Exchangeable Shares.  A United States holder
of Series 1 Exchangeable Shares generally will be required to include in gross
income as ordinary income dividends paid on the Series 1 Exchangeable Shares to
the extent paid out of the current or accumulated earnings and profits of VESI,
as determined under United States federal income tax principles. Such dividends
generally will be treated as foreign source passive income for foreign income
tax credit limitation purposes. Under the Tax Treaty, such distributions will be
subject to Canadian withholding tax at a maximum rate of 15 percent. Subject to
certain limitations of United States federal income tax law, a United States
holder generally should be entitled to credit such withholding tax against such
holder's United States federal income tax liability or to deduct such tax in
computing United States taxable income.
 
     Dissenters.  A United States holder who exercises such holder's right to
dissent from the Arrangement will recognize gain or loss on the exchange of such
holder's Enertec Common Shares for cash in an amount equal to the difference
between the amount of cash received and such holder's basis in the Enertec
Common Shares exchanged. Such gain or loss will be capital gain or loss if the
Enertec Common Shares were held as capital assets at the time of the Effective
Time of the Arrangement, and will be long-term capital gain or loss if the
Enertec Common Shares have been held for more than one year at the time of the
Arrangement.
 
     Passive Foreign Investment Company Considerations.  For United States
federal income tax purposes, a foreign corporation (hereinafter, the "tested
corporation") generally will be classified as a passive foreign investment
company, known as a "PFIC," for any taxable year during which either (i) 75
percent or more of its gross income is passive income (as defined for United
States federal income tax purposes) or (ii) on average for such taxable year, 50
percent or more of its assets produce or are held for the production of passive
income. For purposes of applying the foregoing tests, the assets and gross
income of corporations with respect to which the tested corporation owns at
least 25 percent of the value of the stock will be attributed to the tested
corporation.
 
     While there can be no assurance with respect to the classification of
either Enertec or VESI as a PFIC, each of Enertec and VESI believes that it did
not constitute a PFIC during its taxable years ending prior to consummation of
the Arrangement. At the present time, Enertec and Veritas DGC intend to endeavor
to cause Enertec and VESI to avoid PFIC status in the future, although there can
be no assurance that they will be able to do so or that their intent will not
change. Moreover, because a determination of the tested corporation's status as
a PFIC cannot be made until the close of the taxable year, United States counsel
will not be rendering an opinion with regard to the status of VESI or Enertec as
a PFIC.
 
     After the Arrangement, VESI intends to monitor its status regularly, and
promptly following the end of each taxable year VESI will notify United States
holders of Series 1 Exchangeable Shares if it believes that VESI was a PFIC for
that taxable year.
 
     Although the matter is not free from doubt, if Enertec were a PFIC at any
time during a particular United States holder's holding period for its Enertec
Common Shares, and the United States holder had not made an
 
                                       62
<PAGE>   76
 
election to treat Enertec as a qualified electing fund (a "QEF") under Section
1295 of the United States Internal Revenue Code (a "QEF Election"), then any
gain recognized by a United States holder upon the exchange of Enertec Common
Shares for Series 1 Exchangeable Shares or cash, may be recharacterized as
ordinary income and be subject to the payment of an interest charge under the
same rules described below with respect to VESI.
 
     If VESI is a PFIC following the Arrangement during a United States holder's
holding period for such holder's Series 1 Exchangeable Shares, and the United
States holder does not make a QEF Election, then (1) the United States holder
would be required to allocate income recognized upon receiving certain excess
dividends with respect to, and gain recognized upon the disposition of, such
United States holder's Series 1 Exchangeable Shares (including upon the exchange
of Series 1 Exchangeable Shares for shares of Veritas DGC Common Stock) ratably
over the United States holder's holding period for such Series 1 Exchangeable
Shares, (2) the amount allocated to each year other than (x) the year of the
excess dividend payment or disposition of the Series 1 Exchangeable Shares or
(y) any year prior to the beginning of the first taxable year of VESI for which
it was a PFIC, would be subject to tax at the highest rate applicable to
individuals or corporations, as the case may be, for the taxable year to which
such income is allocated, and an interest charge would be imposed upon the
resulting tax attributable to each such year (which charge would accrue from the
due date of the return for the taxable year to which such tax was allocated),
and (3) amounts allocated to periods described in (x) and (y) will be taxable to
the United States holder as ordinary income.
 
     If the United States holder of Series 1 Exchangeable Shares makes a QEF
Election, then the United States holder generally will be currently taxable on
such holder's pro rata share of VESI's ordinary earnings and net capital gains
(at ordinary income and capital gains rates, respectively) for each taxable year
of VESI in which VESI is classified as a PFIC, even if no dividend distributions
are received by such United States holder, unless such United States holder
makes an election to defer such taxes. If VESI believes that it was a PFIC for a
taxable year, it will provide United States holders of Series 1 Exchangeable
Shares with information sufficient to allow eligible holders to make a QEF
Election and report and pay any current or deferred taxes due with respect to
their pro rata shares of VESI's ordinary earnings and profits and net capital
gains for such taxable year. United States holders should consult their tax
advisors concerning the merits and mechanics of making a QEF Election and other
relevant tax considerations if either Enertec or VESI is a PFIC for any
applicable taxable year.
 
     The foregoing summary of the possible application of the PFIC rules to
Enertec and VESI and the United States holders of Enertec Common Shares is only
a summary of certain material aspects of those rules. Because the United States
federal income tax consequences to a United States holder of Enertec Common
Shares under the PFIC provisions are significant, United States holders of
Enertec Common Shares are urged to discuss those consequences with their tax
advisors.
 
SHAREHOLDERS NOT RESIDENT IN OR CITIZENS OF THE UNITED STATES
 
     The following summary is applicable to holders of Enertec Common Shares
that are not United States holders.
 
     A non-United States holder generally will not be subject to United States
federal income tax on gain (if any) recognized on the receipt of the Series 1
Exchangeable Shares, on the sale or exchange of the Series 1 Exchangeable
Shares, or on the receipt of or sale of shares of Veritas DGC Common Stock
unless such gain is effectively connected with a United States trade or business
or, in the case of gains recognized by an individual, such individual is present
in the United States for 183 days or more and has a "tax home," as defined in
the United States Internal Revenue Code, during the taxable year.
 
     Dividends received by a non-United States holder with respect to the Series
1 Exchangeable Shares should not be subject to United States withholding tax,
and Veritas DGC and Enertec do not intend that Veritas DGC, VESI or Enertec will
withhold any amounts in respect of such tax from such dividends. There is some
possibility, however, that the Internal Revenue Service may assert that United
States withholding tax is payable with respect to dividends paid on the Series 1
Exchangeable Shares to non-United States holders. In such case, holders of
Series 1 Exchangeable Shares could be subject to United States withholding tax
at a rate of 30 percent, which rate may be reduced by an income tax treaty in
effect between the United States and the non-United States holder's
 
                                       63
<PAGE>   77
 
country of residence. This reduction would result in a withholding tax of 15
percent on dividends paid to residents of Canada under the Tax Treaty.
 
     Dividends received by non-United States holders with respect to the Veritas
DGC Common Stock generally will be subject to United States withholding tax at a
rate of 30 percent, which rate may be subject to reduction by an applicable
income tax treaty. This reduction would result in a withholding tax of 15
percent on dividends paid to residents of Canada under the Tax Treaty.

                VERITAS DGC MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the Veritas DGC
Consolidated Financial Statements and Notes thereto.
 
RESULTS OF OPERATIONS
 
     Six months ended January 31, 1999 compared with six months ended January
31, 1998
 
     Revenues.  Revenues decreased 7% from $265.8 million to $248.5 million
during the current six months. The decrease was attributable to fewer data
library sales. Revenues increased for all other service groups compared to the
prior period.
 
     Land and transition zone acquisition revenues increased 10% from $110.7
million to $121.3 million as a result of increased utilization of an expanded
base of crews and channels during the first quarter of the current year.
Operations also improved in the Middle East market during the second quarter;
however, revenues decreased in other areas as a result of decreased demand and
prices.
 
     Marine acquisition revenues increased 4% from $43.5 million to $45.4
million despite disruptions caused by weather and the mobilization of vessels.
The increase was primarily due to capacity added by the Veritas Viking, Veritas
DGC's new 3-D vessel that commenced operations in July 1998.
 
     Data processing revenues were consistent, $45.1 million in the prior year
compared to $45.4 million in the current year. Veritas DGC substantially
upgraded its processing centers, including the addition of a third NEC
supercomputer in Singapore in July 1998, to meet the demand for complex and
computer intensive processing products such as pre-stack time and depth
migration.
 
     Multi-client data library sales decreased 45%, from $66.5 million to $36.4
million, primarily due to the higher level of data sales in the first quarter of
fiscal year 1998 related to a new data sales program in the Gulf of Mexico and
decreased demand in the second quarter of the current year.
 
     Cost of Services.  Cost of services were consistent, $174.1 million in the
prior year compared to $173.5 million in the current year, but increased as a
percent of revenues from 65% to 70%. The reduction in operating margins is
mainly attributable to a more competitive environment in the onshore markets, as
a result of lower commodity prices. Marine acquisition, data processing, and
data library sales operating margins increased due to improvements in
productivity and efficiency and the mix of multi-client surveys sold.
 
     Depreciation and Amortization.  Depreciation and amortization expense
increased 36% from $25.5 million to $34.6 million due to the large increase in
capital expenditures over the past two years.
 
     Selling, General and Administrative.  Selling, general, and administrative
costs increased slightly from $8.8 million in 1998 to $9.1 million in 1999.
 
     Interest Expense.  Interest expense increased from $4.1 million to $5.6
million due to the addition of the $60.0 million senior notes discussed below at
the end of the first quarter in the current year.
 
     Other Income.  The increase in other income from $1.0 to $2.4 million
primarily relates to net foreign currency exchange gains resulting from the
Canadian dollar strengthening against the U.S. dollar. In the prior year,
Veritas DGC recognized losses as the U.S. dollar strengthened against the
Australian dollar. The increase is partially offset by a reduction in interest
income earned as a result of lower average cash balances in the first quarter of
fiscal 1999.
 
     Income Taxes.  Provision for income taxes decreased from $16.2 million to
$8.9 million as a result of Veritas DGC's lower taxable income for the current
year. The increase in the effective tax rate from 30% to 32% is primarily
attributable to a benefit recorded to recognize the expected future utilization
of net operating loss carryforwards during the prior year's second quarter.
 
     Equity in (earnings) loss.  Equity in (earnings) loss is related to the
Indonesian joint venture. A decrease in marine acquisition surveys accounts for
the decreased profitability in the current year.

<PAGE>   79
 
     Fiscal 1998 Compared With Fiscal 1997
 
     Revenues.  For fiscal 1998, revenues increased 46% from $362.7 million to
$529.0 million. Although all service groups improved, multi-client data library
sales showed the largest increase at 151%, from $48.4 million to $121.3 million.
Over the past two years, as oil and gas companies have moved toward multi-client
surveys to reduce finding costs, Veritas DGC has significantly increased its
data library. Sales from the data library primarily involved marine surveys in
the deepwater Gulf of Mexico and North Atlantic.
 
     Land and transition zone acquisition revenues increased 31% from $175.8
million to $229.8 million as a result of additional recording capacity,
resulting from the purchase in late fiscal 1997 of equipment to configure up to
two crews in Oman, the addition of one crew in Latin America, and operating
efficiencies from upgraded and standardized equipment. In Canada, warmer than
usual winter conditions, an extended spring breakup period and a decrease in
deep gas seismic activity had a negative impact on revenues.
 
     Marine acquisition revenues increased 33% from $64.4 million to $85.9
million even though five vessels were in dry dock approximately one month each
for regularly schedule maintenance at various times during the year. The
increase was primarily due to the deployment of additional streamer capacity and
an increase in demand for multi-client surveys, particularly in the Gulf of
Mexico. In addition, beginning in June 1998, Veritas DGC chartered the Veritas
Viking, a new vessel, which set Veritas DGC production records in the brief
period it operated during the year.
 
     Data processing revenues increased 24% from $74.1 million to $92.0 million
as a result of increases in market activity, volume of data acquired in 3D
surveys and demand for computer intensive processes such as prestack time and
depth migration. Veritas DGC has substantially upgraded its processing centers,
including the addition of NEC supercomputers in Crawley, England and Singapore
and several multi-noded workstations, to meet this increased demand.
 
     Cost of Services.  Cost of services increased 28% from $271.7 million to
$346.9 million; but, as a percent of revenues, decreased from 75% to 66%. The
improvement in operating margins is mainly attributable to significant sales and
performance of multi-client data surveys that generally have higher margins.
Data processing operating margins also showed improvement due to more efficient
equipment. Marine acquisition and land and transition zone margins remained
relatively consistent.
 
     Depreciation and Amortization.  Depreciation and amortization expense
increased 38% from $40.6 million to $56.1 million due to the large increase in
capital expenditures over the prior two years.
 
     Selling, General and Administrative.  Selling, general and administrative
expenses increased 65% from $11.4 million to $18.8 million resulting primarily
from the addition of staff to support Veritas DGC's expanded operations and
costs incurred in implementing new administrative and accounting systems and a
more aggressive marketing strategy.
 
     Interest Expense.  Compared with fiscal 1997, interest expense remained
relatively constant in fiscal 1998. Fiscal 1998 interest expense was benefitted
by capitalizing $800,000 of interest incurred in connection with the cost of
outfitting the Veritas Viking.
 
     Other (Income) Expense.  Other (income) expense increased from a loss of
$630,000 to income of $338,000 primarily from interest income earned on higher
average cash balances. This increase was partially offset by net foreign
currency losses resulting from fluctuations in foreign money markets.
 
     Income Taxes.  Provisions for income taxes increased from $6.1 million to
$34.2 million as a result of Veritas DGC's increased profitability. The
effective tax rate increased from 20% to 34%. The fiscal 1997 tax rate was
benefitted by the write-off of certain of Veritas DGC's investments in the prior
year.
 
     Fiscal 1997 Compared With Fiscal 1996
 
     Revenues.  For fiscal 1997, total revenues increased 45% from $250.6
million to $362.7 million. Land and transition zone acquisition revenues
increased 49% from $117.6 million to $175.8 million as a result of higher
demand, additional capacity of 9,000 channels and operating efficiencies from
upgraded and standardized
 
                                       66
<PAGE>   80
 
equipment. Demand improved significantly in Canada and remained high during the
spring break-up period. Contracts in Veritas DGC's other markets had longer
terms, larger channel requirements, better prices and improved weather
protection clauses than in prior years.
 
     Marine acquisition revenues increased 19% from $54.4 million to $64.4
million primarily due to increased utilization of Veritas DGC's vessels, higher
productivity from the upgrade to Syntron equipment, the addition of the Polar
Princess in the first quarter and another short-term chartered vessel in the
fourth quarter.
 
     Data processing operations increased 33% from $55.6 million to $74.1
million due to increases in capacity, productivity and volumes of data available
for processing. Veritas DGC substantially upgraded its processing centers,
installed a NEC supercomputer in Houston and opened new centers in Abu Dhabi,
Australia, Ecuador and Oklahoma.
 
     Multi-client data sales increased 110% from $23.0 million to $48.4 million
due to expanding customer interest in the Gulf of Mexico, especially deepwater
and sub-salt areas, and North Sea multi-client data surveys.
 
     Cost of Services.  Cost of services increased 37% from $198.7 million to
$271.7 million; but, as a percent of revenues decreased from 79% to 75%. The
improvement in operating margins is attributable to higher prices due to
increased market demand, better equipment utilization and higher productivity
for all service groups as discussed above.
 
     Depreciation and Amortization.  Depreciation and amortization expense
increased 51% from $26.9 million to $40.6 million due to the extensive 1997
capital expenditure program.
 
     Selling, General and Administrative.  Selling, general and administrative
expenses increased 57% from $7.3 million to $11.4 million, resulting primarily
from costs incurred in implementing new administrative and accounting systems,
pursuing a more aggressive marketing strategy and from incentive compensation as
a result of Veritas DGC's improved performance.
 
     Interest Expense.  Interest expense increased 37% from $5.5 million to $7.5
million due to increased debt levels required to finance the 1997 capital
expenditure program. Veritas DGC issued $75 million of senior notes during the
year.
 
     Merger Related Costs.  Merger related costs consist primarily of one month
of investment banking and professional fees and expenses incurred in connection
with the combination with VESI.
 
     Income Taxes.  Provision for income taxes increased from $2.0 million to
$6.1 million as a result of increased profitability. However, the effective tax
rate was reduced in the current year by the write-off of certain investments.
 
     Equity in (earnings) loss.  Equity in (earnings) loss is related to the
Indonesian joint venture. An increase in marine acquisition surveys and the sale
of multi-client data library account for the increased profitability of the
joint venture in the current year.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Sources and Uses
 
     Veritas DGC's internal sources of liquidity are cash, cash equivalents and
cash flow from operations. External sources include public and private
financing, the unutilized portion of a revolving credit facility, equipment
financing and trade credit.
 
     In October 1996, Veritas DGC completed a $75.0 million public offering of
senior notes ("Series A Notes"), and in October 1998, Veritas DGC completed a
$60.0 million private placement of senior notes ("Series B Notes"), both due in
October 2003. The Series B Notes were exchanged for notes with terms identical
in all material respects to those of the Series A Notes in March 1999 ("Series C
Notes"). This exchange was registered under the Securities Act. The net proceeds
from the Series B Notes will be used for general corporate purposes, including
capital expenditures and additions to Veritas DGC's data library as discussed
below. The indentures relating to the senior notes contain certain covenants,
including covenants that limit Veritas DGC's
 
                                       67
<PAGE>   81
 
ability to, among other things, incur additional debt, pay dividends, and
complete certain mergers, acquisitions and sales of assets. Veritas DGC is in
compliance with all covenants of the indentures as of January 31, 1999. Upon a
change in control of Veritas DGC, as defined in the indentures, holders of the
senior notes have the right to require Veritas DGC 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 1998, Veritas DGC obtained a new revolving credit facility due July
2001 from commercial lenders that provides advances up to $50.0 million.
Advances are limited by a borrowing base and bear interest, at Veritas DGC's
election, at LIBOR or prime rate plus a margin based on certain ratios
maintained by Veritas DGC. Advances are secured by certain accounts receivable
for a limited amount. The borrowing base is currently in excess of the maximum
commitment as of January 31, 1999. Covenants in the agreement limit, among other
things, Veritas DGC's right to take certain actions, including creating
indebtedness. In addition, the agreement requires Veritas DGC to maintain
certain financial ratios. Veritas DGC is in compliance with all covenants of the
agreement. There were no outstanding advances as of January 31, 1999.
 
     Veritas DGC requires significant amounts of working capital to support its
operations and to fund capital spending and research and development programs.
Veritas DGC'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. In
addition, receivables and payables denominated in foreign currencies are subject
to fluctuations in foreign money markets. Approximately 47% of revenues for the
six months ended January 31, 1999 were attributable to Veritas DGC's foreign
operations. Veritas DGC has also increased its participation in multi-client
data surveys and has significantly expanded its multi-client data library.
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, Veritas DGC's liquidity will be
affected; however, Veritas DGC believes that these non-exclusive surveys have
good long-term sales, earnings and cash flow potential.
 
     Veritas DGC's revised capital budget for fiscal 1999 is $76.3 million,
which includes expenditures of $30.0 million to maintain or replace Veritas
DGC's current operating equipment and $48.8 million to expand capacity. Research
and development costs are estimated at $8.2 million in fiscal 1999.
 
     Veritas DGC 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. However, Veritas DGC's ability to meet its
obligations depends on its future performance, which, in turn, is subject to
general economic conditions, business and other factors beyond Veritas DGC's
control. Many oil and gas companies have recently announced annual budgets that
are substantially lower than previously anticipated. Key factors affecting
future results will include utilization levels for both land and marine crews
and the level of data library sales. The ability to forecast future earnings is
more difficult as a result of a substantial reduction in backlog ($149.0 million
at January 31, 1999 compared to $227.0 million at January 31, 1998). The
continued deterioration in activity levels and current industry outlook will
result in a very difficult environment for the balance of fiscal 1999.
 
     Management has undertaken certain initiatives in response to the current
industry downturn to preserve the financial strength and flexibility of Veritas
DGC. Since September 1998, headcount has been decreased from approximately 4,500
to 2,500 employees. Veritas DGC has decommissioned the multi-boat operation in
the Gulf of Mexico. All three vessels, which were on short-term charters, have
been returned to the vessel owners. In order to reduce capital expenditures, the
seismic equipment outfitting these vessels will be installed on the second
Viking class 3D vessel, which is scheduled for delivery in May 1999. Management
continues to monitor discretionary capital expenditures.
 
     Veritas DGC anticipates that cash and cash equivalents, cash flow from
operations, the unutilized portion of the revolving credit facility and
borrowings permitted under the indentures and revolving credit facility will
provide sufficient liquidity to fund these requirements through fiscal 1999. If
Veritas DGC is unable to generate sufficient cash flow from operations or
otherwise to comply with the terms of the revolving credit facility or the
indentures, it may be required to refinance all or a portion of its existing
debt or obtain additional financing.
                                       68
<PAGE>   82
 
Veritas DGC cannot assure that it would be able to obtain such refinancing or
financing, or that any refinancing or financing would result in a level of net
proceeds required.
 
     Other
 
     Veritas DGC has prepared a formal plan to address Year 2000 issues as they
relate to Veritas DGC's business and its operations. In accordance with that
plan, Veritas DGC has evaluated all internal hardware and software used in its
operations, including those used to support Veritas DGC's activities, such as
seismic data acquisition and processing equipment and accounting and payroll
systems. In the ordinary course of business, Veritas DGC has replaced a
significant amount of its hardware and software with Year 2000 compliant
systems. A replacement schedule has been prepared for its remaining
non-compliant systems and an ongoing monitoring program and contingency
procedures in the event of unanticipated non-compliance problems have been
established. Veritas DGC has also identified all external relationships, mainly
suppliers and customers, and mailed each entity an internally prepared
questionnaire regarding Year 2000 issues. Responses returned indicate a state of
readiness and non-responses do not pertain to critical systems. As of January
31, 1999, Veritas DGC estimates that it will complete its plan, including
remedial actions, by June 30, 1999. Approximately $100,000 of costs have been
incurred. Veritas DGC is not aware of any additional material contingencies or
costs that will be incurred.
 
     Since Veritas DGC'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, 1999, Veritas DGC recognized $2.9
million related to these benefits, due to increased profitability of Veritas
DGC's U.K. operations.
 
     Veritas DGC maintains operations in Europe, which are predominately
conducted from its U.K. offices. Although the U.K. has not currently elected to
convert to the new "euro" currency, Veritas DGC does have transactions with
companies in countries that have adopted the new currency. Veritas DGC has made
a preliminary assessment and does not anticipate any material effect to the
consolidated financial statements as a result of the new currency.
 
     See Note 1 of Notes to Veritas DGC Consolidated Financial Statements
regarding new accounting pronouncements not yet adopted.

                            BUSINESS OF VERITAS DGC
 
GENERAL
 
     Veritas DGC is a leading provider of seismic data acquisition, data
processing, multi-client data surveys and information services to the oil and
gas industry in selected markets worldwide. Oil and gas companies utilize
seismic data for the determination of suitable locations for drilling
exploratory wells and, increasingly, in reservoir management for the development
and production of oil and gas reserves. Veritas DGC acquires seismic data on
land and in marine and transition zone environments, and processes data acquired
by its own crews and crews of other operators. Veritas DGC acquires seismic data
both on an exclusive contractual basis for its customers and on its own behalf
for licensing to multiple customers on a non-exclusive basis.
 
INDUSTRY CONDITIONS
 
     In recent years, worldwide demand for three-dimensional surveys by major
oil and gas companies and independent producers has increased. The greater
precision and improved subsurface resolution obtainable from three-dimensional
seismic data have assisted oil and gas companies in finding new fields and more
accurately delineating existing fields, as well as enhancing existing reservoir
management and production monitoring techniques. Enhanced subsurface resolution
obtainable from three-dimensional studies has been a key factor in improving
drilling success ratios and lowering finding and field extension costs. This
improved technology, coupled with advances in drilling and completion
techniques, is enhancing the industry's ability to develop oil and gas reserves,
particularly in transition zone and deepwater environments.
 
     Overall demand for seismic services is dependent upon the level of
expenditures by oil and gas companies for exploration, production, development
and field management activities, which depends in part on present and expected
future oil and natural gas prices. The oil and gas industry is currently
operating in an environment of low hydrocarbon commodity prices and a resulting
reduced level of industry activity. Low hydrocarbon commodity prices and reduced
industry expenditures are expected for the near term and could have an adverse
effect on the demand for Veritas DGC's services, results of operations and cash
flows.
 
COMPANY OVERVIEW
 
     Geophysical services enable oil and gas companies to determine whether
subsurface conditions are likely to be favorable for finding new oil and gas
accumulations and assist oil and gas companies in determining the size and
structure of previously identified oil and gas fields. These services consist of
the acquisition and processing of seismic data, which are used to produce
computer-generated images and cross-sections of the subsurface strata. These are
then analyzed and interpreted by customers' geophysicists and used by oil and
gas companies in the acquisition of new leases, the selection of drilling
locations on exploratory prospects and in reservoir development and management.
 
     Land and transition zone data acquisition.  Each of Veritas DGC's land and
transition zone data acquisition crews consists of a surveying unit that lays
out the lines to be recorded, an explosives or mechanical vibrating unit and a
recording unit that lays out the geophones and recording instruments. Veritas
DGC utilizes helicopters to aid its crews in seismic data acquisition in
situations where such use will reduce overall costs and improve productivity.
Veritas DGC's land and transition zone data acquisition services are currently
conducted by six seismic crews operating in three countries. In fiscal 1998,
land and transition zone data acquisition accounted for approximately 43% of
Veritas DGC's revenues.
 
     Marine data acquisition.  Veritas DGC's marine data acquisition crews
operate primarily on chartered vessels equipped with a full complement of
seismic, navigational and communications equipment. Veritas DGC currently
operates six vessels, with three located in the Gulf of Mexico and the remainder
in international markets. All of Veritas DGC's six seismic vessels are capable
of performing two-dimensional seismic surveys and three are equipped to perform
three-dimensional seismic surveys. During the last several years, a majority of
Veritas DGC's marine seismic acquisition services involved three-dimensional
surveys. In fiscal 1998, marine data acquisition accounted for approximately 16%
of Veritas DGC's revenues.
 
                                       70

     Data processing.  Veritas DGC currently operates 21 data processing
centers. These centers process data acquired by Veritas DGC's own crews, as well
as crews of other operators. Because they are configured primarily for
processing large-scale offshore surveys, three of these centers operate NEC
supercomputers supported by high speed networks. The other 18 centers, which are
utilized mainly for smaller scale land seismic surveys, operate data processing
systems equipped primarily with Sun Microsystems workstations. In fiscal 1998,
data processing accounted for approximately 18% of Veritas DGC's revenues.
 
     Licensing of multi-client data surveys.  Veritas DGC also acquires and
processes seismic data for its own account by conducting surveys either
partially or wholly funded by multiple customers. In this mode of operation,
Veritas DGC retains ownership of the data and licenses this data on a
non-exclusive basis. In fiscal 1998, the licensing of multi-client data surveys
accounted for 23% of Veritas DGC's revenues. However, this percentage does not
include the portion of Veritas DGC's data acquisition and processing revenues
that is recognized prior to completion of a multi-client data survey.
 
BUSINESS STRATEGY
 
     Veritas DGC's objective is to enhance its position as a leading provider of
seismic services while seeking to maximize earnings and cash flow. To achieve
these goals, Veritas DGC employs the following business strategy:
 
          Invest in leading technology.  Veritas DGC intends to continue to
     upgrade its data acquisition and processing equipment as often as necessary
     to maintain technological capabilities that are comparable or superior to
     those of its competitors. From the beginning of fiscal 1994 through fiscal
     1998, Veritas DGC invested approximately $292 million to replace or
     substantially upgrade its principal geophysical operating assets. This
     investment in the latest available seismic technology has resulted in
     increased operating efficiency and capacity.
 
             Land and transition zone data acquisition.  Veritas DGC's
        transition zone crews are equipped with Input/Output System Two Remote
        Seismic Recorder systems, and land crews employ either Input/ Output
        System Two or Sercel 388 equipment.
 
             Marine data acquisition.  Five of Veritas DGC's six seismic data
        acquisition vessels have been upgraded to Syntron recording systems. The
        Veritas Viking, a new chartered flagship vessel constructed to Veritas
        DGC's specifications, entered service during fiscal 1998. A second
        Viking class vessel is under construction and is expected to enter
        service in May 1999. Each is capable of deploying more than 12 seismic
        streamer cables.
 
             Data processing.  Veritas DGC's 21 seismic data processing centers
        employ the latest available technology. To improve its speed and
        capacity in processing large three-dimensional marine surveys, Veritas
        DGC has recently installed NEC supercomputers in its Singapore; Crawley,
        England; and Houston processing centers.
 
          Invest in multi-client data library.  At July 31, 1998, Veritas DGC's
     multi-client data library included approximately 1.8 million line
     kilometers of seismic survey data. Due to increased industry demand for
     multi-client surveys in fiscal 1998, revenue from data library sales for
     the year aggregated approximately $121.3 million, a 151% increase over such
     sales in fiscal 1997. Veritas DGC intends to continue its recent and
     increasing emphasis on multi-client surveys and expects to increase the
     book carrying value of its multi-client data library from $51.1 million at
     July 31, 1998 to approximately $115 million by the end of fiscal 1999. The
     relatively expensive cost of acquiring and processing seismic data has
     prompted many oil and gas companies to participate in multi-client surveys
     to reduce geophysical expenses, particularly in light of current conditions
     in the oil and gas industry.
 
          Focus on select geographic markets.  Veritas DGC deploys its land and
     transition zone crews and seismic vessels in geographic areas where it can
     establish and maintain a strong competitive presence.
 
          Maintain flexible marine operations.  In its marine seismic data
     acquisition activities, Veritas DGC presently operates five chartered
     vessels, four of which have unexpired charter terms ranging from one to
     three years, subject to renewal at Veritas DGC's option in most instances.
     It currently owns one vessel and
 
                                       71
<PAGE>   85
 
     has options to acquire an interest in the two Viking class vessels referred
     to above. Veritas DGC's current strategy is to charter vessels, with a view
     to reducing vessel costs in times of low demand, while retaining the
     flexibility to relocate its marine seismic equipment onto vessels that may
     better meet customers' evolving requirements. In general, Veritas DGC also
     seeks to operate a technically balanced fleet of vessels with operating
     characteristics that efficiently serve those markets experiencing the
     greatest demand.

(1)  Revenues from data acquisition and data processing services are recognized
     based on contractual rates set forth in the related contract if the
     contract provides a separate rate for each service provided. If the
     contract only provides a rate for the overall service, revenues are
     recognized based on the percentage of each service group's cost to total
     cost.
 
(2)  Includes export sales of $4,774, $4,115 and $458 in fiscal 1996, 1997 and
     1998, respectively.
 
     Geophysical services are marketed from Veritas DGC's corporate offices and
from its regional administrative centers by personnel whose duties also
typically include technical, supervisory or executive responsibilities.
Contracts are obtained either through competitive bidding in response to
invitations for bids, by direct negotiation with the prospective customer or
through the initiation by Veritas DGC of surveys for its data library.
 
     Contracts for exclusive data acquisition involve payments on either a
turnkey method or a time basis. Under the turnkey method, payments for services
are based upon the amount of data collected or processed, and Veritas DGC bears
substantially all of the risk of business interruption caused by inclement
weather and other hazards. When operating on a time basis, payments are based on
agreed rates per unit of time. Certain risks of business interruption are shared
in agreed percentages by Veritas DGC and the customer. In each case, progress
payments are usually required unless it is expected that the job can be
accomplished in a brief period.
 
     Land and Transition Zone Acquisition
 
     Veritas DGC's land and transition zone acquisition services are performed
with seismic equipment using the latest technology. The equipment is capable of
collecting both two-dimensional and three-dimensional data, has a combined
recording capacity of approximately 31,000 channels and can be configured to
operate up to 21 crews.
 
                                       72
<PAGE>   86
 
A majority of Veritas DGC's land and transition zone acquisition services
involve three-dimensional surveys. Veritas DGC is currently operating a total of
six crews located in three countries.
 
     Each crew consists of: a surveying unit which lays out the lines to be
recorded and marks the site for shot-hole placement or equipment location; an
explosive or mechanical vibrating unit; and a recording unit that lays out the
geophones and recording instruments, directs shooting operations and records the
acoustical signal reflected from subsurface strata. On a typical land seismic
survey, the seismic crew is supported by several drill crews, which are
typically furnished by third parties under short-term contracts. Drill crews
operate in advance of the seismic crew and bore shallow holes for explosive
charges which, when detonated by the seismic crew, produce the necessary
acoustical impulse. In locations where the use of explosives is precluded due to
population density, technical requirements or ecological factors, a mechanical
vibrating unit or compressed air is substituted for explosives as the acoustical
source.
 
     Veritas DGC uses helicopters to aid its crews in seismic data acquisition
in situations where such use will reduce overall costs and improve productivity.
In a helicopter supported project, narrower seismic lines are cut than when
trucks are used for transportation. The use of helicopters is often required in
rugged terrain and environmentally sensitive areas and results in better access
and reduced surface damage.
 
     Marine Acquisition
 
     Marine acquisition services are carried out by Veritas DGC's crews
operating primarily from chartered vessels which have been modified or equipped
to Veritas DGC's specifications. The following table sets forth certain
information concerning Veritas DGC's geophysical vessels:

Veritas Viking....................   1998      Gulf of Mexico          305 feet    72 feet
</TABLE>
 
     The Polar Search, Polar Princess and Professor Kurentsov are chartered from
ship operators for initial terms which expire in January 2000, February 2000 and
August 2001, respectively. The Veritas Viking is chartered from a ship owner on
an initial term which expires in June 2006. The Ross Seal is operated under a
short-term charter arrangement which expires December 31, 1999. These charters
contain certain options for Veritas DGC to extend terms at rates closely
approximating the expiring terms and rates. Decisions on whether to extend the
expiring vessel charters or enter into charters with other vessel owners will be
made prior to each charter expiration date. Veritas DGC owns the Acadian
Searcher.
 
     Each vessel generally has an equipment complement consisting of seismic
recording instrumentation, digital seismic streamer cable, cable location and
seismic data location systems, multiple navigation systems, a source control
system which controls the synchronization of the energy source and a firing
system which generates the acoustical impulses. The streamer cable contains
hydrophones that receive the acoustical impulses reflected by variations in the
subsurface strata. Data acquired by each channel in the digital cable is
partially processed before it is transmitted to recording instruments for
storage on magnetic media, thus reducing subsequent processing time and the
effective acquisition costs to the customer.
 
     At present, three of Veritas DGC's vessels are equipped with multiple
streamers and multiple energy sources, which acquire more lines of data with
each pass, reducing completion time and the effective acquisition cost. The
Veritas Viking, Veritas DGC's largest vessel, entered service in fiscal 1998 and
is capable of deploying more than 12 seismic streamer cables. Veritas DGC has
signed an eight-year charter for another Viking class vessel, a sister ship to
the Veritas Viking, which is expected to begin service in May 1999.
 
                                       73
<PAGE>   87
 
     Each marine seismic crew consists of approximately 20 persons, excluding
the ship's captain and ship personnel. Seismic personnel live aboard the ship
during their tours of duty, which are staggered to permit continuous operations.
During seismic operations, Veritas DGC's personnel direct the positioning of the
vessel using sophisticated navigational equipment, deploy and retrieve the
seismic streamer cable and energy-source array and operate all other systems
relating to data collection activities. Veritas DGC's personnel do not, however,
have ultimate responsibility for chartered vessels, which are operated by the
captain and personnel who are employees of the vessel owner.
 
     Data Processing
 
     A majority of Veritas DGC's data processing services are performed on
three-dimensional seismic data. At each of its centers, data received from the
field, both from Veritas DGC and other geophysical contractors, is processed to
produce an image of the earth's subsurface using proprietary computer software
and techniques developed by Veritas DGC. Veritas DGC also reprocesses older
seismic data using new techniques designed to enhance the quality of the data.
 
     Veritas DGC's data processing centers have opened at various times from
1996 through 1998 and are located in:

</TABLE>
 
     Veritas DGC's centers operate high capacity, advanced technology data
processing systems based on NEC, SUN, SGI and HP computer systems with
high-speed networks. These systems utilize Veritas DGC's proprietary seismic
data processing software. The marine and land data acquisition crews have
software identical to that utilized in the processing centers, allowing for ease
in the movement of data from the field to the data processing centers. Veritas
DGC operates both land and marine data processing centers and tailors the
equipment and software deployed in an area to meet the local market demands.
 
     To improve its speed and capacity in processing large three-dimensional
surveys, Veritas DGC installed a NEC supercomputer in its Houston processing
center in July 1996. The success of this first system led to the installation of
additional systems in the Crawley center in August 1997 and in the Singapore
center in July 1998. These supercomputer installations act as global resources
for all of Veritas DGC's data processing operations. In 1998 Veritas DGC
completed the installation of a state-of-the-art visualization center in its
Houston processing center. The center allows customers to display and manipulate
large amounts of three-dimensional seismic data on a 18 by 7 foot screen.

     Data Library Sales
 
     Veritas DGC often acquires and processes data for its own account for
licensing to customers on a non-exclusive basis. Veritas DGC seeks pre-funding
commitments from multiple customers for a large portion of the cost of these
surveys to reduce investment risk. In recent years, Veritas DGC has generally
received commitments in excess of 70%; however, changing market conditions could
reduce commitment levels in the future. Once acquired and processed, these
surveys are then licensed for use to other customers on a non-exclusive basis.
Factors considered in determining whether to undertake such surveys include the
availability of initial participants to underwrite a percentage of the costs,
the location to be surveyed, the probability and timing of future lease
concessions and development activity in the area and the availability, quality
and price of competing data.
 
     The relatively expensive cost of acquiring and processing seismic data has
prompted many oil and gas companies to participate in multi-client surveys to
reduce their geophysical expenses. In response to this increased demand, Veritas
DGC is adding to its data library, primarily in the Gulf of Mexico, the North
Atlantic and Asia Pacific, as well as onshore in Mississippi, Wyoming and Texas.
 
TECHNOLOGY AND CAPITAL EXPENDITURES
 
     The geophysical industry is highly technical, and the requirements for the
acquisition and processing of seismic data have evolved continuously during the
past 50 years. Accordingly, it is of significance to Veritas DGC that its
technological capabilities are comparable or superior to those of its
competitors, whether through continuing research and development, strategic
alliances with equipment manufacturers or by acquiring technology under license
from others. Veritas DGC has introduced several technological innovations in its
geophysical service business that have become industry standard practice in both
acquisition and processing.
 
     Currently, Veritas DGC employs approximately 60 persons in its research and
development activities, substantially all of whom are scientists, engineers or
programmers. During fiscal 1996, 1997 and 1998, research and development
expenditures were $3.2 million, $3.7 million, and $6.2 million, respectively.
 
     Veritas DGC rarely applies for patents on internally developed technology.
This policy is based upon the belief that most proprietary technology, even
where regarded as patentable, can be more effectively protected by maintaining
confidentiality than through disclosure and a patent enforcement program.
Certain of the equipment, processes and techniques used by Veritas DGC are
subject to the patent rights of others, and Veritas DGC holds non-exclusive
licenses with respect to a number of such patents. While Veritas DGC regards as
beneficial its access to others' technology through licensing, Veritas DGC
believes that substantially all presently licensed technology could be replaced
without significant disruption to the business should the need arise.
 
     The capital expenditure program for fiscal 1999 requires expenditures of
approximately $76.3 million, and another $8.2 million is budgeted for research
and development activities. The level of future capital expenditures will depend
on the availability of funding and market requirements as dictated by oil and
gas company activity levels.
 
     The following table sets forth a summary of Veritas DGC's capital
expenditures for the three years ended July 31, 1998.

COMPETITION AND OTHER BUSINESS CONDITIONS
 
     The acquisition and processing of seismic data for the oil and gas
exploration industry has historically been highly competitive worldwide. As a
result of changing technology and increased capital requirements, the seismic
industry has consolidated substantially since the late 1980's. The largest
competitors remaining in the market are Western Geophysical (a division of Baker
Hughes Inc.), Geco-Prakla (a division of Schlumberger), Compagnie Generale
Geophysique and Petroleum Geo-Services ASA. Management believes Veritas DGC is
the fifth largest provider of geophysical services based on associated revenues.
Competition for available seismic surveys is based on several competitive
factors, including price, crew experience, equipment availability, technological
expertise and reputation for quality and dependability.
 
     Veritas DGC's data acquisition activities often are conducted under extreme
weather and other hazardous conditions. Accordingly, these operations are
subject to risks of injury to personnel and loss of equipment. Veritas DGC
carries insurance against the destruction of, or damage to, its chartered
vessels, geophysical equipment and property and injury to persons that may
result from its operations and considers the amounts of such insurance to be
adequate. Veritas DGC may not be able to obtain insurance against certain risks
or for equipment located from time to time in certain areas of the world.
Veritas DGC obtains insurance against war, expropriation, confiscation and
nationalization when such insurance is available and when management considers
it advisable to do so. Such coverage is not always available and, when
available, is subject to unilateral cancellation by the insuring companies on
short notice. Veritas DGC also carries insurance against pollution hazards.
 
     Fixed costs, including costs associated with vessel charters and operating
leases, labor costs, depreciation, and interest expense, account for a
substantial percentage of Veritas DGC's costs and expenses. As a result,
downtime or low productivity resulting from reduced demand, equipment failures,
weather interruptions or otherwise, can result in significant operating losses.
 
BACKLOG
 
     At January 31, 1999, Veritas DGC's backlog of commitments for services was
$149.0 million, compared with $227.0 million at January 31, 1998. It is
anticipated that a majority of the January 31, 1999 backlog will be completed in
the next 12 months. This backlog consists of written orders or commitments
believed to be firm. Contracts for services are occasionally varied or modified
by mutual consent and in certain instances are cancelable by the customer on
short notice without penalty. As a result of these factors, Veritas DGC's
backlog as of any particular date may not be indicative of Veritas DGC's actual
operating results for any succeeding fiscal period.
 
SIGNIFICANT CUSTOMERS
 
     Historically, Veritas DGC's principal customers have been international oil
and gas companies, foreign national oil companies and independent oil and gas
companies. No single customer accounted for 10% or more of total revenues during
the last three fiscal years.
 
EMPLOYEES
 
     At January 31, 1999, Veritas DGC had approximately 2,500 full-time
employees. With the exception of 350 unionized employees working at the
Singapore data processing center or on Argentina land crews, none of its
employees are subject to collective bargaining agreements. Veritas DGC considers
the relations with its employees to be good.

DESCRIPTION OF VERITAS DGC CAPITAL STOCK
 
     The Veritas DGC Restated Certificate of Incorporation authorizes 40,000,000
ordinary shares, consisting of a series of one share of VESI Special Voting
Stock and all other shares being designated as common stock, and 1,000,000
shares of Veritas DGC Preferred Stock. If the Charter Amendment is approved, the
Veritas DGC Restated Certificate of Incorporation will authorize a series of
ordinary shares, consisting of one share designated as ERS Special Voting Stock.
For a detailed description of the capital stock of Veritas DGC, see "The
Companies After the Transaction -- Veritas DGC Capital Stock."
 
     Rights Plan
 
     Pursuant to a Rights Agreement between Veritas DGC and ChaseMellon
Shareholder Services, L.L.C., Dallas, Texas (the "Rights Plan"), each share of
Veritas DGC Common Stock has attached to it one right (the "Right"), represented
by the certificate which is also the certificate representing the Veritas DGC
Common Stock. Each Right entitles the registered holder to purchase from Veritas
DGC one one-thousandth of a share of Series A Junior Participating Preferred
Stock, par value $.01 per share (the "Series A Preferred Stock"), of Veritas DGC
at a purchase price of $100, subject to adjustment (the "Purchase Price").
 
     The Rights will separate from the Veritas DGC Common Stock and a
"Distribution Date" will occur upon the earlier of (i) 10 business days
following a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired, or obtained the right
to acquire, beneficial ownership of 15% or more of the outstanding shares of
Veritas DGC Common Stock (the "Stock Acquisition Date"), or (ii) 10 business
days (or such later date as the Veritas DGC board may determine with the
concurrence of a majority of Continuing Directors (defined below) then in office
and subject to five Continuing Directors then being in office) following the
commencement of a tender or exchange offer which would result in a person or
group beneficially owning 15% or more of such outstanding shares of Veritas DGC
Common Stock (the "Tender Offer Date"). Until the Distribution Date, the Rights
will be transferred with and only with the Veritas DGC Common Stock
certificates. The Rights are not exercisable until after the Distribution Date,
subject to termination of any extended redemption periods described below.
Unless earlier redeemed by Veritas DGC as described below, the Rights will
expire at the close of business on May 15, 2007.
 
     In the event that, among other things, (i) Veritas DGC is the surviving
corporation in a merger or other business combination with an Acquiring Person
or (ii) any person shall become the beneficial owner of more than 15% of the
outstanding shares of the Veritas DGC Common Stock (except (A) pursuant to
certain consolidations or mergers involving Veritas DGC or sales or transfers of
the combined assets or earning power of Veritas DGC and its subsidiaries, or (B)
pursuant to an offer for all outstanding shares of the Veritas DGC Common Stock
at a price and upon terms and conditions which a majority of the Continuing
Directors determines to be in the best interests of Veritas DGC and its
stockholders) each holder of a Right (other than the Acquiring Person, certain
related parties and transferees) will thereafter have the right to purchase,
upon exercise, a one-thousandth fractional share interest in Series A Preferred
Stock each of which is for all purposes essentially equivalent to a share of
Veritas DGC Common Stock (or, in certain circumstances, cash, property or other
securities of Veritas DGC) having a value equal to two times the exercise price
of the Right. For example, at the exercise price of $100 per Right, each Right
not owned by an Acquiring Person (or by certain related parties and transferees)
following an event set forth above would entitle its holder to purchase $200
worth of Series A Preferred Stock (or other consideration, as noted above) for
$100. Assuming that the Series A Preferred Stock had a per one-thousandth share
market price of $40 at such time (with each one-thousandth share of Series A
Preferred Stock valued at one share of Veritas DGC Common Stock), the holder of
each valid Right would be entitled to purchase five one-thousandth shares of the
Series A Preferred Stock for $100. Rights are not exercisable following the
occurrence of any of the events described above until the Rights are no longer
redeemable by Veritas DGC as described below. Notwithstanding any of the
foregoing, following the occurrence of any of the events described in this
paragraph, all Rights that are, or (under certain circumstances specified in the
Rights Plan) were, beneficially owned by any Acquiring Person will be null and
void.
 
     In the event that, at any time following the Stock Acquisition Date, (1)
Veritas DGC is acquired in a merger or other business combination transaction in
which Veritas DGC is not the surviving corporation, (2) Veritas DGC
 
                                       82
<PAGE>   96
 
is the surviving corporation in a consolidation or merger pursuant to which all
or part of the outstanding shares of Veritas DGC Common Stock are changed into
or exchanged for stock or other securities of any other person or cash or any
other property or (3) more than 50% of the combined assets or earning power of
Veritas DGC and its subsidiaries is sold or transferred (in each case other than
certain consolidations with, mergers with and into, or sales of assets or
earning power by or to subsidiaries of Veritas DGC as specified in the Rights
Agreement), each holder of a Right (except Rights that previously have been
voided as set forth above) shall thereafter have the right to receive, upon
exercise, Veritas DGC Common Stock of the acquiring company having a value equal
to two times the exercise price of the Right. The events described in this
paragraph and in the immediately preceding paragraph are referred to as the
"Triggering Events."
 
     At any time until 10 business days following the Stock Acquisition Date (or
such later date as the Veritas DGC board may determine with the concurrence of a
majority of the Continuing Directors then in office), Veritas DGC may redeem the
Rights in whole, but not in part, at a price of $.001 per Right (payable in
cash, shares of Veritas DGC Common Stock or other consideration deemed
appropriate by the board of directors). Rights may not be redeemed during the
180 day period after any person becomes an Acquiring Person unless the
redemption is approved by a majority of Continuing Directors. The term
"Continuing Director" means any member of the Veritas DGC board who was a member
of the board prior to the date of the Rights Agreement, and any person who is
subsequently elected to the board if such person is recommended or approved by a
majority of at least five Continuing Directors, but shall not include an
Acquiring Person, or an affiliate or associate of an Acquiring Person, or any
representative of the foregoing persons.
 
     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of Veritas DGC, including, without limitation, the right
to vote or to receive dividends.
 
     The Rights have certain anti-takeover effects. They may reduce or eliminate
(1) "two-tiered" or other partial offers that do not offer fair value for all
Veritas DGC Common Stock; (2) the accumulation by a third party of 15% or more
of the Veritas DGC Common Stock in open-market or private purchases in order to
influence or control the business and affairs of Veritas DGC without paying an
appropriate premium for a controlling position in Veritas DGC; and (3) the
accumulation of shares of Veritas DGC Common Stock by third parties in market
transactions for the primary purpose of attempting to cause Veritas DGC to be
sold. In addition, the Rights will cause substantial dilution to a person or
group that attempts to acquire Veritas DGC in a manner defined as a Triggering
Event unless the offer is conditioned on a substantial number of Rights being
acquired. The Rights, however, should not affect any prospective offeror willing
to make an offer for all outstanding shares of Veritas DGC Common Stock and
other voting securities at a price and on other terms that are in the best
interests of Veritas DGC and its stockholders as determined by the Veritas DGC
board or affect any prospective offeror willing to negotiate with the board of
directors because as part of any negotiated transaction the Rights would either
be redeemed or otherwise made inapplicable to the transaction. The Rights should
not interfere with any merger or other business combination approved by the
board of directors since the Veritas DGC board may, at its option, at any time
until ten business days following the Stock Acquisition Date, redeem all, but
not less than all, of the then outstanding Rights at the $.001 redemption price.
 
LEGAL PROCEEDINGS
 
     Various claims have been filed against Veritas DGC in the ordinary course
of business, particularly claims alleging personal injuries. Management believes
that Veritas DGC has established adequate reserves on its books for any
liabilities that may reasonably be expected to result from these claims. In the
opinion of management, no pending or threatened claims, actions or proceedings
against Veritas DGC are expected to have a material adverse effect on Veritas
DGC's financial position or results of operations.

                                BUSINESS OF VESI
 
GENERAL
 
     VESI was founded in 1974 and is governed by the ABCA. VESI, a subsidiary of
Veritas DGC, provides land-based seismic data acquisition services, seismic data
processing services and exploration and development information services in
Canada.
 
     VESI was acquired by Veritas DGC in August, 1996. At that time, VESI was
granted orders by Canadian securities regulators exempting VESI from certain
continuous disclosure requirements. Those exemptions were granted on the basis
that the VESI Exchangeable Shares are the economic equivalent of Veritas DGC
Common Stock, such that the holders of such exchangeable shares essentially have
a participatory interest in Veritas DGC, and that Veritas DGC is subject to the
continuous disclosure requirements of the SEC and the applicable U.S. and
Canadian regulatory authorities. Accordingly, all financial information
concerning VESI is included in the consolidated financial statements of Veritas
DGC. Also, the description of the business of Veritas DGC included in this Joint
Proxy Statement encompasses the businesses of the subsidiaries of Veritas DGC,
including VESI.

                ENERTEC MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the Enertec
Consolidated Financial Statements and Notes thereto.
 
RESULTS OF OPERATIONS
 
     Four months ended January 31, 1999 compared with four months ended January
31, 1998
 
     Revenues.  Consolidated net revenues declined 36% to C$16.7 million from
C$26.2 million during the current four months. This decrease was the result of
curtailed demand for seismic services resulting from the weakness in world oil
prices.
 
     Data acquisition net revenues decreased by 51% to C$9.1 million from C$18.5
million due to both declining demand and lower prices, the latter a result of
excess geophysical acquisition capacity in the North American market.
 
     Marine services net revenues increased by 6% to C$4.8 million from C$4.5
million as a result of marginally better weather and sustained demand for
Enertec's services in the Gulf of Mexico, despite a general slow-down for marine
services in this geographic region.
 
     Data processing net revenues declined by 4% to C$3.0 million from C$3.2
million. This decline was the result of a marked decrease in demand in the
Canadian market, partially mitigated by an increase in demand for Enertec's
services in the U.S. market.
 
     Inter-segment sales of C$0.2 million have been eliminated in reporting
Enertec's consolidated net revenue.
 
     Operating Margin.  The operating margin declined to C$2.5 million from
C$7.4 million; as a percentage of net revenue the margin declined to 15% from
28%. The majority of these declines were attributable to the data acquisition
operation which experienced a negative operating margin for the current four
months due to difficulties on a contract in the U.S. The marine operation's
margin declined slightly as a result of lower prices caused by a weakening in
demand for marine services in the Gulf of Mexico.
 
     Research and Development.  Research and development expenses increased by
25% to C$0.5 million from C$0.4 million, as a result of Enertec's continued
focus on technology.
 
     General and Administrative.  General and administrative expenses increased
by 13% to C$1.35 million from C$1.2 million. The increase is primarily
attributable to engaging the services of financial advisors and legal counsel to
assist with acquisition opportunities.
 
     Depreciation and Amortization.  Depreciation and amortization increased by
11% to C$3.1 million from C$2.8 million. This increase results from capital
asset additions subsequent to January 31, 1998 and the amortization of goodwill
arising from the acquisition of the assets and business of Extend Seismic
Processing LLC in June 1998.
 
     Income Taxes.  Income taxes declined to a recovery of C$1.7 million from a
provision of C$1.2 million as a result of losses incurred in the current period
compared to a profitable comparative period.
 
     Fiscal 1998 compared with fiscal 1997
 
     Revenues.  Consolidated net revenues declined 4% to C$68.1 million from
C$70.7 million during the 1998 fiscal year. Despite a record second quarter in
1998, customer concerns relating to the Asian economic malaise and its potential
to keep oil prices low for a protracted period negatively impacted the remainder
of the year.
 
     Data acquisition net revenues decreased 16% to C$39.0 million from C$46.3
million. The majority of this decline occurred in Canada, with the remainder
occurring in the U.S. Despite relatively strong natural gas prices in Canada,
the weakness in oil prices was a primary factor in the reduction in Canadian
customer demand. In the U.S. the erosion in demand for proprietary data
acquisition services was partially as a result of competitors offering customers
cost reductions by providing them with data on a non-exclusive and
non-transferable basis. In
 
                                       85
<PAGE>   99
 
the latter part of the fiscal year, Enertec undertook the acquisition of data on
this basis in the U.S., recording revenue of C$2.1 million in respect of such
sales.
 
     Marine services net revenues rose 18% to C$20.2 million from C$17.0 million
through the continuation of the steady growth trend of this business since its
acquisition in 1995. This growth occurred as a result of increased customer
acceptance in this market and the development of additional strategic alliances
with existing and new customers.
 
     Data processing net revenues increased 20% to C$8.9 million from C$7.4
million. While Canadian operations revenue declined slightly, U.S. revenues more
than offset this decline with strong growth in the Houston-based operation and
the new business generated from the acquisition in June 1998 of the New Orleans-
based marine data processing operation of Extend Seismic Processing.
 
     Operating Margin.  Operating margin declined by 8% to C$22.3 million from
C$24.1 million; as a percentage of net revenue the operating margin fell to 33%
in 1998 from 34% in 1997. The decline in the operating margin was a result of
decreases in the margin contributions of both the Canadian and U.S. data
acquisition operations, partially mitigated by increases in margin from both the
data processing and marine services businesses.
 
     Research and Development.  Research and development expense increased by
40% to C$1.4 million from C$1.0 million, as a result of Enertec's continuing
focus on technology.
 
     General and Administrative.  General and administrative expense declined
25% to C$4.0 million from C$5.3 million. The decline was primarily due to the
expiration in 1998 of the three year performance bonus paid to certain employees
in the marine services operation under their employment contracts. Another
contribution to the decline was the discontinuation of the operations of a new
oil field service venture.
 
     Depreciation and Amortization.  Depreciation and amortization increased 9%
to C$9.2 million from C$8.4 million. This increase resulted from the capital
expenditures undertaken to update Enertec's vibrator fleet, capital expenditures
in the marine services operation and the goodwill arising on the purchase of the
assets and business of Extend Seismic Processing.
 
     Income Taxes.  Income taxes remained at a consistent 30% of earnings before
income taxes in both 1998 and 1997, with only a change in the deferred/current
composition within each year.
 
     Fiscal 1997 compared with fiscal 1996
 
     Net Revenues.  Consolidated net revenues grew by C$23.8 million, or 51%, to
C$70.7 million from C$46.9 million in the 1996 fiscal year. The demand for
geophysical services reached a peak during 1997 as oil and gas companies strove
to generate increased production in a market characterized by strong oil prices
and increasing natural gas prices.
 
     Slightly more than C$16.0 million of Enertec's net revenue increase was
from the data acquisition business, with both the Canadian and U.S. operations
making a strong contribution. The Canadian contribution resulted from both an
increase in demand for Enertec's services and improved prices. In the U.S.
prices changed little between the two years, but Enertec increased its market
share.
 
     The marine services operation made a C$4.4 million contribution to
Enertec's net revenue increase. This was achieved through increased market share
and the strong growth in activity in the Gulf of Mexico. This increased demand
was met by the addition of a fourth geophysical vessel in the summer of 1997.
 
     The data processing operation made a C$3.2 million contribution to
Enertec's net revenue increase. While this was the smallest contribution to
Enertec's overall revenue increase, this operation grew by 78% during the year
through the addition of new customers in Canada and through expansion in the
U.S.
 
     Operating Margin.  The operating margin increased by C$11.2 million, or
87%, to C$24.1 million from C$12.9 million; as a percentage of net revenue the
operating margin increased to 34% in 1997 from 28% in 1996.
 
                                       86
<PAGE>   100
 
     The data acquisition operation contributed C$7.2 million of Enertec's
overall margin increase, with 56% of this being contributed by the United States
operation and 44% by the Canadian operation.
 
     Marine services provided C$1.6 million of the overall margin increase
mainly through expansion of its survey capability to include deep water
conditions, where most of the Gulf of Mexico activity was occurring.
 
     The data processing business contributed C$2.4 million of Enertec's C$11.2
million margin increase. The majority of this contribution was provided by
Canadian operations which increased revenue while maintaining a relatively low
cost structure.
 
     Research and Development.  Expenditures increased to C$1.0 million from
C$0.8 million, or 25%, as a result of both the data acquisition and data
processing operations efforts to develop products to meet the unique needs of
clients or improve technology generally.
 
     General and Administrative.  The C$1.9 million, or 56%, increase in general
and administrative expense to C$5.3 million from C$3.4 million is primarily the
result of three factors. The performance bonus paid to certain employees in the
marine services operation under their employment contracts increased by C$1.1
million. In addition, the commencement of a new oil field service venture
incurred expenses of C$0.4 million, and Enertec's employee incentive bonus rose
by C$0.3 million due to the improved performance of Enertec in 1997.
 
     Depreciation and amortization.  Depreciation and amortization increased 13%
to C$8.4 million from C$7.4 million as a result of incurring C$11.3 million of
capital expenditures, mostly in the first half of the 1997 fiscal year and also
from the write-down of a data acquisition recording system which had suffered
technological obsolescence.
 
     Interest Expense.  Interest expense declined by 50% to C$0.4 million from
C$0.8 million because of the repayment of all Enertec's bank debt from the
issuance of common stock during the third fiscal quarter.
 
     Other Income.  Other income increased to C$0.6 million from a small expense
amount in 1996. This income is primarily comprised of discounts received by
paying suppliers earlier than Enertec's standard credit terms and gains on the
disposition of capital assets.
 
     Income Taxes.  Income tax expense increased to C$2.9 million from a
recovery of C$0.5 million, as a result earnings before taxes of C$9.5 million in
1997 compared to C$0.5 million in 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At January 31, 1999, Enertec's indebtedness under its bank lines of credit
was C$8.2 million, net of cash balances. At January 31, 1999, Enertec's Canadian
and U.S. bank borrowing facility limits were C$15 million and $1.1 million,
respectively.
 
     In the four months ended January 31, 1999, Enertec repurchased and
cancelled 179,600 of its common shares at a cost of C$972,000, an average cost
of C$5.41 per share.
 
     In light of the curtailment in demand for Enertec's services resulting from
the protracted low oil price environment, staff reductions and other cost
reduction initiatives were instituted. In addition, the capital budget for
fiscal 1999 was reduced to C$4.2 million from C$6.1 million. Of this reduced
budget, C$1.5 million is designated for the purchase of a vessel in the marine
services operation, and the balance of C$2.7 million is to maintain or replace
Enertec's current operating equipment. Enertec anticipates that cash flow from
operations and the unutilized portion of its bank credit facilities will provide
sufficient liquidity to maintain its operations through fiscal 1999. In the
event that cash flow from operations is less than anticipated, Enertec will
invoke additional cost reduction measures.
 
BUSINESS RISKS
 
     The main risks faced by Enertec are low activity levels in the oil and gas
industry, the weather adversely affecting operations and the loss of market
share to competitors. Currently it is Enertec management's belief that activity
levels in the oil and gas industry are the preeminent risk, followed by
competition from others.
 
                                       87
<PAGE>   101
 
     At this time Enertec is acutely aware of the risk posed by declines in the
levels of capital expenditures by its customers. While Enertec cannot insulate
itself from a chronic downturn in oil and gas prices, it has deployed strategies
to attempt to minimize the negative influences from such an event.
 
     In its largest product line, the data acquisition operation, Enertec has
avoided acquiring the capacity to enable it to meet the full extent of the
demand for its services in the Canadian winter months. Demand in excess of
Enertec's capacity is dealt with by the rental of equipment, if available at
economically viable rates. If such rental equipment is not available, demand for
services is declined.
 
     Enertec has sought to expand its data processing product line recently.
This business is not capital intensive, lends itself well to the securing of
proprietary positions in the marketplace through the offering of particular
technologies and services, and has a good profit margin on revenues. During the
1998 fiscal year Enertec was successful in acquiring the previously mentioned
marine data processing business in New Orleans and was also involved in the
detailed review of two other data processing businesses the acquisitions of
which were not consummated.
 
     Through the marine services product line, Enertec has diversified its
business into an area that is not as susceptible to oil and gas price weakness
as are data processing and, particularly, land data acquisition. This product
line services the exploration, development and production engineering facets of
the Gulf of Mexico oil and gas infrastructure. The Gulf is an area of activity
for multinational entities whose plans for development are expected to be halted
only by a downturn of significant severity and duration. The marine services
product line has fostered and succeeded in expanding the number of its strategic
alliances with customers who are active in this area.
 
     Enertec is reducing costs in the areas of its business where activity
declines are occurring, most notably at this time in the land data acquisition
business.
 
     The perceived second most prevalent risk at this time is, as stated,
competition from others. The product line that management believes is the most
vulnerable to competition is the data acquisition operation. The service offered
by this operation is the one most likely to be subject to price undercutting or
risk assumption by Enertec's competitors. Risk assumption through the
multi-client data library acquisition format is a currently prevalent practice
in this business. As mentioned previously, Enertec has, to date, undertaken two
such acquisition surveys and will be considering undertaking further surveys for
its library.
 
     The risk of inclement weather affects both the data acquisition and marine
services product lines. This risk is mitigated, where possible, by having the
client assume or at least share the risk.
 
YEAR 2000 SYSTEMS PREPARATIONS
 
     Enertec develops and purchases its computer application software and
primarily purchases its systems operating software. Enertec has contacted the
suppliers of its purchased hardware and software to establish whether their
products that it is using are Year 2000 compliant. Most of this hardware and
software is of relatively recent vintage and is represented to be already
compliant. In addition, Enertec is frequently in contact with these suppliers
regarding updates relative to this issue.
 
     During the review of the state of readiness of Enertec's systems, an
assessment has been made of the areas where risk of non-compliance is perceived.
Remedial work and testing of the computer systems has been underway for some
time and will continue through the first nine calendar months of 1999. Enertec
expects to have completed the work necessary in order to be year 2000 compliant
by the end of September 1999. Enertec believes that the cost of rendering the
company year 2000 compliant is unlikely to exceed $100,000.
 
     Enertec has assessed which suppliers of day to day goods and services it is
most dependent on and has identified these as the suppliers of electricity,
telecommunications services, satellite positioning signals, motor fuel and
equipment parts. With respect to the entities supplying these categories of
goods and services, Enertec believes it is not in a position to influence the
progress of these parties on their Year 2000 preparations. In addition, it is
felt that these entities are acutely aware of the need to be compliant in a
timely manner and that fuel and telecommunication services are available from
more than one supplier. Equipment supplies are either
 
                                       88
<PAGE>   102
 
available from more than one supplier or will be inventoried if Enertec has
supply concerns. Enertec will use its best efforts to ensure that its operations
are not disrupted by this issue, however it cannot be certain that it will not
suffer a disruption to its business activities.
 
OUTLOOK
 
     The protracted weakness in the oil market has abated to a certain extent
with the recent production cut announcements by certain OPEC and other oil
producing countries. However, the recent upward momentum in the price of crude
oil may reverse if compliance with the production cuts is weak. At this time
some of Enertec's customers are planning certain geophysical expenditures in
light of the price improvement. Others however, are being cautious and not
considering additional expenditures until they feel that current price levels or
better are sustainable.
 
     The data acquisition product line is expected to be the one most affected
by the weak oil market. It is in this operation that the most stringent cost
reduction measures are being undertaken.
 
     While the data processing product line will be affected by the weak market,
management of Enertec believes that the impact will not be as strong as in the
data acquisition operation. This belief is based on the fact that those
customers of Enertec which have a relatively high proportion of natural gas to
oil will remain quite active. These customers are expected to have the cash flow
required to undertake the capital expenditures they need to increase gas
production to meet their new transportation pipeline commitments and reap the
anticipated higher price of natural gas in the U.S. market. In addition, a
number of customers are expected to be prepared to undertake the expenditures
necessary to have old data reprocessed, seeking improved information on their
properties. This is a far less costly option than having new data acquired and
processed.
 
     The marine services product line management believes that certain of
Enertec's customers operating in the Gulf of Mexico are likely to continue
working, albeit at a restrained pace. Through the quality of the services it
offers, this product line has established strategic alliances with companies
active in the Gulf. Management of Enertec believes that the relationships it has
with its customers will help to mitigate the impact of the price competition
that may arise if competitors choose this strategy.
 
     Enertec's prospects and the future results of its operations are subject to
certain risks, uncertainties and assumptions. Should one or more of these risks
or uncertainties materialize or should the assumptions prove incorrect, actual
results may vary in material respect from those currently anticipated.

COMPANY OVERVIEW
 
     Enertec is a Calgary, Alberta based company which is actively engaged in
the business of land-based and shallow marine seismic data acquisition, seismic
data processing and marine geophysical surveying and positioning services in
North America and, occasionally, in certain international markets. Enertec is a
full service provider of state-of-the-art geophysical technology to the oil and
natural gas industry.
 
     Enertec acquires and processes two-dimensional, three-dimensional and
four-dimensional seismic data. Enertec provides both seismic data acquisition
and processing services thereby offering its customers savings in time and cost,
as well as higher quality control for their overall needs. Enertec also provides
a professional seismic data acquisition design service to its customers from its
Calgary seismic data acquisition office and believes it is one of only a few
such contractors offering these design services. This service entails working
with customers to determine the optimal configuration for the recording of
seismic data over their area of interest. This service is provided as a value
added, no cost benefit for Enertec's customers, provided the customer utilizes
Enertec's seismic data acquisition services. Enertec views this service as an
integral component of its marketing program.
 
     Enertec has developed proprietary software to analyze seismic data and to
produce various displays and presentations. On-going development of Enertec's
proprietary software is a high priority research project that is conducted by
its employees.
 
     In March of 1994, Enertec acquired all of the outstanding shares of Seismic
Data Processors Ltd. ("SDP"), a seismic data processing company. This
acquisition allowed Enertec to provide seismic data processing services to its
customers. SDP had operated for 15 years before it was acquired by Enertec.
 
     Effective June 14, 1995, Enertec acquired, through its wholly-owned
subsidiary KC Offshore, L.L.C., the principal operating assets, and retained the
key personnel, of Kinsella Cook & Associates Inc. ("Kinsella Cook"), and
directly acquired all of the outstanding shares of Kinco, operating in the
offshore geophysical, positioning and construction surveying industry in the
United States. Both of these companies were based in
 
                                       90
<PAGE>   104
 
Baton Rouge, Louisiana. These acquisitions permitted Enertec to expand its range
of services to include marine geophysical and positioning services.
 
     Effective April 1, 1996, Enertec acquired all of the outstanding shares in
PowerProbe Geophysics Inc. ("PowerProbe"), a company offering an electrical
methods exploration and development service. PowerProbe has the exclusive rights
in Canada and the United States to utilize and market an electrical methods
technique which has the potential to enhance the assessment of the presence of
hydrocarbons beneath the surface of the earth. This technology requires further
development before it may have commercial application. Effective April 1, 1996,
PowerProbe amalgamated with EGSL.
 
     In the 1997 fiscal year, Enertec established a new product line
("Enprotec") specializing in reservoir and production engineering applications
designed to enhance hydrocarbon production. This operation offered services to
oil and natural gas companies to optimize production from existing petroleum
reservoirs. In fiscal 1998, the venture was discontinued due to a lack of
interest on the part of oil and gas companies to enter into agreements whereby
Enprotec would receive a portion of any enhanced production in exchange for
financing and undertaking production enhancement work on their property.
 
     Effective June 2, 1998, Enertec acquired, through its wholly-owned
subsidiary, Enertec Geophysical Services L.L.C., the principal operating assets,
and retained the personnel, of Extend Seismic Processing L.L.C. ("Extend").
Extend was based in New Orleans, Louisiana and primarily involved in marine
seismic data processing. This acquisition added deep-water two-dimensional and
three-dimensional seismic processing capabilities to Enertec and expanded
Enertec's presence in the United States.
 
SEISMIC DATA ACQUISITION
 
     Acquisition Technology
 
     Enertec uses digital distributed systems for seismic data acquisition.
Currently, Enertec uses a sigma delta 24 bit system. This system has a low
weight per channel which is important for helicopter applications.
 
     Helicopter-Supported Operations
 
     Environmental concerns have made the cutting of traditional seismic lines
undesirable in many areas. The relatively light weight of distributed systems,
coupled with the speed of deployment of equipment, has made helicopter assisted
operations more desirable than land-based techniques in certain sensitive areas.
It also allows Enertec to work during all seasons in areas that would
traditionally be restricted to winter frozen ground conditions. In rugged or
difficult terrain, the speed of recording is considerably faster utilizing
helicopter transportation rather than wheeled or tracked vehicles. Currently,
Enertec charters fully-crewed helicopters from third party operators for about
50% of its land-based seismic data acquisition work.
 
     Vibroseis
 
     Enertec presently owns and operates 28 servo-hydraulic vibrators. Twelve of
these vibrators are mounted on six wheel drive trucks that are suitable for
general farmland type operations or frozen ground operations in the winter.
Another 12 vibrators are mounted on buggies for areas with softer ground
conditions and four are mounted on tracks. The tracked units are specifically
designed for operation in the Arctic. Enertec's crews have the technical
expertise to use either vibroseis or dynamite as the energy source.
 
     United States Operations
 
     Enertec commenced providing seismic data acquisition services in the United
States in 1995. Since that time, Enertec has developed considerable experience
gathering seismic data in the transition zone along the Gulf of Mexico. This
transition zone includes tidally influenced and swamp land and also shallow
marine areas offshore. Enertec has also expanded its land-based seismic
acquisition operations, primarily in the State of Texas. Enertec operates
offices in Houston, Texas and Baton Rouge, Louisiana, and has successfully
completed projects in Texas, Louisiana, Oklahoma and Wyoming. In late fiscal
1998 and early fiscal 1999, Enertec undertook the
 
                                       91
<PAGE>   105
 
acquisition of seismic data for its own multi-client data library. These data
are sold to customers on a non-exclusive and non-transferable basis.
 
     Arctic Operations
 
     Arctic operations require specialized equipment designed to withstand the
harsh conditions encountered in the northern region. Enertec believes that it is
the only Canadian owned geophysical services seismic contractor which has the
equipment and experience to operate in the Arctic. Enertec has undertaken
numerous projects in Alaska and the Canadian Arctic and many of Enertec's
personnel have experience working in Arctic conditions.
 
SEISMIC DATA PROCESSING
 
     Enertec currently markets its seismic data processing services to its
existing seismic data acquisition customers and to current and new customers
requiring only seismic data processing services. A customer may achieve cost
savings by using both seismic data acquisition and data processing services
through price reductions and time saved in producing final products for
interpretation, as well as a higher degree of quality control. Enertec's seismic
data processing business helps to reduce the seasonality of Enertec's
operations.
 
     Enertec operates seismic data processing centres based in Calgary, Alberta,
Houston, Texas and New Orleans, Louisiana and processes seismic data acquired by
Enertec and other contractors, utilizing advanced proprietary software developed
by its own research and development team. In addition to new seismic data,
Enertec's customers often review and require reprocessing of existing seismic
data from their own data base or data that may be purchased from other
companies.
 
     Enertec's software operates on a variety of processing platforms, allowing
Enertec to process data at customized low capital cost centres for customers in
various Canadian, United States or other international locations.
 
MARINE SERVICES
 
     Enertec acquired the principal operating assets, and retained the key
personnel, of Kinsella Cook in June, 1995 through KC Offshore, L.L.C., a
wholly-owned subsidiary of Enertec. This acquisition permitted Enertec to expand
its services to include marine geophysical and positioning services. KC Offshore
is based in Baton Rouge, Louisiana and is a full-service provider of offshore
surveying in the Gulf of Mexico. KC Offshore currently operates three specially
equipped vessels, two of which are owned and one of which is leased by Enertec.
Through KC Offshore, Enertec provides marine geophysical surveys and positioning
services to, and prepares related technical reports for, the oil and natural gas
industry.
 
     Geophysical Surveying Services
 
     Enertec provides high-resolution geophysical surveys which map the hazards
existing on the sea floor. Governmental regulations in the United States require
these surveys to be conducted prior to the issuance of a permit to operators
planning to conduct exploration or construction in a particular area. To conduct
these surveys, Enertec employs its own high technology vessel (the "R/V
Albuquerque") and a suite of remote sensing devices which identify natural and
man-made features that can have an impact on, or endanger, an oil and natural
gas project. KC Offshore, and its predecessor in interest, Kinsella Cook, has
extensive experience in geophysical hazard surveying and, to date, has
successfully completed over 600 such surveys in the northern Gulf of Mexico. In
response to the increasing interest in deeper water exploration and development
in the Gulf, KC Offshore has advanced its capabilities and is able to conduct
seafloor surveys at greater depths than previously. Enertec also often conducts
intermediate depth seismic exploration for customers concurrently with the
provision of high-resolution geophysical surveys.
 
     Positioning Services
 
     KC Offshore's positioning service involves finding the coordinates of a
particular location offshore and guiding the customer to that location. This
task is quite complicated in the open sea; however, using its
 
                                       92
<PAGE>   106
 
differential global positioning system reference station network and internally
developed software and expertise, KC Offshore is able to guide a customer to
within three metres of a particular offshore location.
 
     Enertec also uses its positioning service to provide underwater site
abandonment clearance as required by the Minerals Management Service NTL 92-02
Regulation (United States). Pursuant to this regulation, once a platform or well
has been removed by an operator, the operator must verify that the seafloor is
clear of debris and that no trawling obstructions exist. Enertec conducts site
reconnaissance to locate debris and trawling operations to clear the sea bed of
site debris. The rate of well and platform abandonments in the Gulf of Mexico
has increased in the last several years. Enertec uses leased vessels to meet the
demand for these services.
 
     Technical Reports and Computations
 
     Enertec's ability to plan survey operations, perform geophysical data
interpretation and prepare professional report presentations adds to Enertec's
full-service marine geophysical capabilities. Enertec believes it is the only
marine surveying company operating in the Gulf of Mexico with a staff marine
archaeologist to undertake technical reporting.
 
SAFETY
 
     Management of Enertec considers providing a safe work environment to be one
of Enertec's prime responsibilities. Enertec has developed comprehensive safety
policies and operating procedures to which all of Enertec's personnel are
expected to strictly adhere. The board of directors of Enertec has established
the Safety and Environment Committee in order to monitor Enertec's safety
procedures. Enertec manages safety responsibilities as a prime contractor on
behalf of its customers. Enertec's safety program is constantly being reviewed
and improved by its management, often based upon feedback from employees.
Enertec remains a safety leader and participates in industry association
initiatives to continually improve its safety practices.
 
PREMISES
 
     Enertec owns its Canadian seismic data acquisition base offices and
facilities, which are located at 3024 - 49th Avenue S.E., Calgary, Alberta, T2B
2X4. These offices and facilities are located on a site approximately 2.2 acres
in size, with a building consisting of approximately 6,200 square feet of office
space and approximately 6,500 square feet of shop area. Enertec leases its head
office space and its Canadian seismic data processing facility, which are
located on the 8th and 9th floors of Rocky Mountain Plaza, 615 Macleod Trail
S.E., Calgary, Alberta, T2G 4T8. The head office and seismic data processing
facility together consist of approximately 20,900 square feet of office space.
Enertec also leases an office and warehouse in Houston, Texas. The office at
3300 S. Gessner, Houston, Texas, 77063, houses the United States seismic data
acquisition operation, a marketing arm of Enertec's marine services operation
and one of the seismic data processing operations. The other operation is
located at an office leased at 3330 W. Esplanade, Suite 601, Metairie,
Louisiana, 70002. The marine services operation is located at an office leased
at 36499 Perkins Road, Prairieville, Louisiana, 70769. The real property owned
by Enertec is subject to fixed and floating charges under Enertec's banking
facilities.
 
CUSTOMERS
 
     Management of Enertec is of the view that several factors are considered by
Enertec's customers in selecting a geophysical services contractor, including
price, availability of required technology, experience (both personnel and
corporate), financial stability of the contractor, safety and environmental
policy and record of the contractor, and reputation of the contractor for
quality and productivity. Enertec believes that it is able to successfully
compete in all these areas.
 
     There are approximately 500 Canadian and several hundred United States oil
and natural gas companies. Enertec focuses its marketing efforts on
approximately 75 of these companies. One major Canadian customer accounted for
an average of approximately 31% of Enertec's revenue during the last three
fiscal years. Another repeat customer group of approximately seven companies
traditionally generates approximately another 20% of Enertec's annual revenue.
 
                                       93
<PAGE>   107
 
     Enertec has cultivated a long term position with regard to the pricing of
its services and has formed strategic alliances with customers of similar
philosophy pursuant to which there is an understanding as to the provision and
price of such services. Enertec has access to customer information which
provides sufficient time to organize its services to provide maximum benefits to
its customers in the areas of expertise and reliability in the provision of
seismic data acquisition services, reduced costs, good public relations on
behalf of the customer, timely service, technical advice and reduced liability
potential.
 
     Enertec's seismic data acquisition agreements with its customers are for
varying terms. These agreements may generally be terminated on 30 days notice.
 
     The continuing low oil price environment and global oversupply of oil have
caused a significant contraction in demand for seismic data acquisition services
and a somewhat less severe reduction in demand for seismic data processing and
marine services.
 
COMPETITION
 
     Enertec operates in a cyclical industry, dependent principally upon the
level of exploration and development activities of oil and natural gas
companies. Since 1986, significant rationalization has occurred in the Canadian
geophysical services industry reducing the number of competitors in Canada from
approximately 40 in 1986 to approximately 20 at present.
 
     Technological change, in the form of computer applications which produce
the enhanced imaging characteristics of three-dimensional seismic and
four-dimensional seismic, has created certain barriers to competition through
the increased capital cost and operating skills required by the new equipment.
At the same time, the improved results obtained by oil and natural gas users of
three-dimensional seismic and four-dimensional seismic establishes the basis for
solid growth in the future.
 
RESEARCH AND DEVELOPMENT
 
     The primary focus for Enertec's research and development program is on
seismic data processing software and applications, with a secondary focus on
seismic data acquisition techniques. This focus on research and development is
intended to produce proprietary software, increase productivity, and provide a
long term marketing advantage for Enertec. Each member of Enertec's 14 person
research and development team is a professional engineer or geophysicist with an
aggregate of over 100 years of experience.
 
     During the 1998 fiscal year, a joint venture between Enertec and Mobil Oil
Corporation implemented a new technology which Enertec has termed as Sei-Fi.
This technology can be used to significantly improve the resolution of
two-dimensional and three-dimensional seismic data or alternatively to reduce
the cost of the acquisition of the data through productivity efficiencies in the
field. Sei-Fi has been in demand from certain customers but has not yet
generated the full potential of the demand anticipated by management of Enertec
due to the current malaise in the oil and gas industry.
 
     For the year ended September 30, 1998, Enertec incurred expenses of
approximately C$1.4 million in connection with its research and development
activities.
 
EMPLOYEES
 
     Enertec currently employs approximately 263 people, with 150 in its seismic
data acquisition business (of which approximately 90 are seasonal employees), 49
in its seismic data processing business, 60 in marine services, and three in
corporate administration. Enertec's personnel includes approximately 36
engineers, computer scientists and geophysicists.

entitled to a lump sum payment equal to a specified number of months of
remuneration and to the continuation of medical, dental and insurance coverage
for the same specified number of months. In respect of Murray A. Olson, the
specified number of months is 30, in respect of the other Named Executive
Officers, the specified number of months is 24.
 
     Directors' Compensation
 
     Each director of Enertec, other than any directors who are also employees
of Enertec, is entitled to receive an annual fee of C$10,000. Effective December
10, 1998 and each December thereafter, directors may elect to receive this
annual fee either in cash or as a number of stock options issued on the terms of
the Enertec Option Plan. Each director is also entitled to receive a fee of
C$1,000 for each board meeting attended, C$500 for each committee meeting
attended and C$500 for each board or committee meeting attended by telephone and
is reimbursed for expenses incurred for such meetings. Directors who are
employees of Enertec are not entitled to receive any fees for services rendered
to Enertec as a director.
 
     As a component of their compensation, directors are granted 2000 stock
options per annum in order to align an element of their remuneration with
shareholder rewards. Newly nominated directors of Enertec receive 10,000 stock
options upon their appointment as a director. These options are granted in terms
of the Enertec Option Plan.
 
     The Chairman of Enertec, in addition to his duties as Chairman, actively
assists management of Enertec with issues such as the formulation and execution
of strategic plans, business acquisition assessment, marketing philosophy,
compensation and corporate governance. For the performance of these additional
duties, he is paid C$2,000 per month. In the event the Chairman devotes time in
excess of one and a half to two days per month to assisting management, he will
charge Enertec at the rate of C$1,500 per day. During 1998, no charge for excess
time was made.
 
     No director, executive officer or senior officer of Enertec was indebted to
Enertec since the commencement of the last completed fiscal year.
 
DESCRIPTION OF ENERTEC SHARE CAPITAL
 
     The authorized share capital of Enertec consists of an unlimited number of
class 1 preferred shares (the "Preferred Shares"), issuable in series, and an
unlimited number of Enertec Common Shares. As at March 22, 1999 there were no
Preferred Shares and 6,931,668 Enertec Common Shares issued and outstanding.
 
     Preferred Shares
 
     The Preferred Shares are issuable in series, have a preference with respect
to the payment of dividends and the distribution of assets in the event of
liquidation, dissolution or winding-up over the Enertec Common Shares and any
shares ranking junior to the Preferred Shares and are non-voting unless
otherwise provided with respect to any series of such class. Subject to the
provisions of the ABCA, the provisions applicable to the class of Preferred
Shares generally and to the provisions of any outstanding series, the Enertec
board is authorized to fix, from time to time, before issue thereof, the
designation, rights, privileges, restrictions and conditions attaching to each
series of such class of shares.
 
     Under the Arrangement, the articles of Enertec will be amended so as to
delete the Preferred Shares from Enertec's authorized share capital.
 
     Enertec Common Shares
 
     The Enertec Common Shares are entitled to one vote per share at all
meetings of shareholders of Enertec except meetings at which only holders of a
specified class or series of shares are entitled to vote. Subject to the prior
rights and privileges attaching to any other class of shares of the Enertec, the
Enertec Common Shares have the right to receive any dividend as and when
declared by the Enertec board and the right to receive the remaining assets of
the Enertec upon liquidation, dissolution or winding-up.

LEGAL PROCEEDINGS
 
     There are no material legal proceedings to which Enertec, or any of its
subsidiaries is a party nor to which any of their property is subject, nor to
the best of the knowledge of the board of directors and senior officers of
Enertec or any of its subsidiaries, are any such proceedings threatened or
contemplated by any person.
 
AUDITORS, REGISTRAR AND TRANSFER AGENT
 
     The auditors of Enertec are KPMG LLP Chartered Accountants 1200, 205 - 5th

                        COMPARISON OF STOCKHOLDER RIGHTS
 
     In the event that the Transaction is consummated, holders of Enertec Common
Shares will, at the Effective Time, transfer their Enertec Common Shares to VESI
and the sole consideration received therefor will be Series 1 Exchangeable
Shares. Such holders will have the right to retract Series 1 Exchangeable Shares
for an equivalent number of shares of Veritas DGC Common Stock. Enertec is a
corporation governed by the ABCA. Veritas DGC is a corporation organized under
the DGCL. While the rights and privileges of shareholders of an Alberta
corporation are, in many instances, comparable to those of stockholders of a
Delaware corporation, there are certain differences. These differences arise
from differences between Alberta and Delaware law, between the ABCA and DGCL and
between the Enertec articles of incorporation and bylaws and the Veritas DGC
Restated Certificate of Incorporation and Veritas DGC bylaws. For a description
of the respective rights of the holders of Enertec Common Shares and Veritas DGC
Common Stock, see, respectively, "Business of Enertec -- Description of Enertec
Share Capital" and "The Companies After the Transaction -- Veritas DGC Capital
Stock."
 
VOTE REQUIRED FOR EXTRAORDINARY TRANSACTIONS
 
     Under the ABCA, certain extraordinary corporate actions, such as certain
amalgamations, continuances, and sales, leases or exchanges of all or
substantially all the property of a corporation other than in the ordinary
course of business, and other extraordinary corporate actions such as
liquidations, dissolutions and (if ordered by a court) arrangements, are
required to be approved by special resolution. A special resolution is a
resolution passed at a meeting by not less than two-thirds of the votes cast by
the shareholders, present in person or by proxy, at the meeting. In certain
cases, a special resolution to approve an extraordinary corporate action is also
required to be approved separately by the holders of a class or series of
shares.
 
     The DGCL requires the affirmative vote of a majority of the outstanding
stock entitled to vote to authorize any merger, consolidation, dissolution or
sale of substantially all of the assets of a corporation, except that, unless
required by its certificate of incorporation:
 
     -  no authorizing stockholder vote is required of a corporation surviving a
        merger if (1) such corporation's certificate of incorporation is not
        amended by the merger, (2) each share of stock of such corporation will
        be an identical share of the surviving corporation after the merger, and
        (3) the number of shares to be issued in the merger does not exceed 20%
        of such corporation's outstanding common stock immediately prior to the
        effective date of the merger; and
 
     -  no authorizing stockholder vote is required of a corporation to
        authorize a merger with or into a single direct or indirect wholly-owned
        subsidiary of such corporation (provided certain other limited
        circumstances apply).
 
The Veritas DGC Restated Certificate of Incorporation does not require a greater
percentage vote for such actions. Stockholder approval is also not required
under the DGCL for mergers or consolidations in which a parent corporation
merges or consolidates with a subsidiary of which it owns at least 90% of the
outstanding shares of each class of stock.
 
AMENDMENT TO GOVERNING DOCUMENTS
 
     Under the ABCA, any amendment to the articles generally requires approval
by special resolution, which is a resolution passed by a majority of not less
than two-thirds of the votes cast by shareholders entitled to vote on the
resolution. The ABCA provides that unless the articles or by-laws otherwise
provide, the directors may, by resolution, make, amend or repeal any by-laws
that regulate the business or affairs of a corporation. Where the directors
make, amend or repeal a by-law, they are required under the ABCA to submit the
by-law, amendment or repeal to the shareholders at the next meeting of
shareholders, and the shareholders may confirm, reject or amend the by-law,
amendment or repeal by an ordinary resolution, which is a resolution passed by a
majority of the votes cast by shareholders entitled to vote on the resolution.
 
     The DGCL requires a vote of the corporation's board of directors followed
by the affirmative vote of a majority of the outstanding stock entitled to vote
for any amendment to the certificate of incorporation, unless a
                                       102
<PAGE>   116
 
greater level of approval is required by the certificate of incorporation. The
Veritas DGC Restated Certificate of Incorporation does not require a greater
level of approval for an amendment. If an amendment would have the effect of
altering the powers, preferences or special rights of a particular class or
series of stock, the class or series has the power to vote as a class
notwithstanding the absence of any specifically enumerated power in the
certificate of incorporation. The DGCL also states that the power to adopt,
amend or repeal the by-laws of a corporation shall be in the stockholders
entitled to vote, provided that the corporation in its certificate of
incorporation may confer such power on the corporation's board of directors.
 
DISSENTERS' RIGHTS
 
     The ABCA provides that shareholders of an Alberta corporation entitled to
vote on certain matters are entitled to exercise dissent rights and to be paid
the fair value of their shares in connection therewith. The ABCA does not
distinguish for this purpose between listed and unlisted shares. Such matters
include:
 
     -  any amalgamation with another corporation (other than with certain
        affiliated corporations);
 
     -  an amendment to the corporation's articles to add, change or remove any
        provisions restricting or constraining the issue or transfer of shares;
 
     -  an amendment to the corporation's articles to add, change or remove any
        restriction upon the business or businesses that the corporation may
        carry on;
 
     -  a continuance under the laws of another jurisdiction;
 
     -  a sale, lease or exchange of all or substantially all the property of
        the corporation other than in the ordinary course of business;
 
     -  a court order permitting a shareholder to dissent in connection with an
        application to the court for an order approving an arrangement proposed
        by the corporation; or
 
     -  certain amendments to the articles of a corporation which require a
        separate class or series vote, provided that a shareholder is not
        entitled to dissent if an amendment to the articles is effected by a
        court order approving a reorganization or by a court order made in
        connection with an action for an oppression remedy.
 
Under the ABCA, a shareholder may, in addition to exercising dissent rights,
seek an oppression remedy for any act or omission of a corporation or any of its
affiliates which is oppressive, unfairly prejudicial to or that unfairly
disregards a shareholder's interest.
 
     Under the DGCL, holders of shares of any class or series have the right, in
certain circumstances, to dissent from a merger or consolidation by demanding
payment in cash for their shares equal to the fair value (excluding any
appreciation or depreciation as a consequence or in expectation of the
transaction) of such shares, as determined by agreement with the corporation or
by an independent appraiser appointed by a court in an action timely brought by
the corporation or the dissenters. The DGCL grants dissenters' appraisal rights
only in the case of mergers or consolidations and not in the case of a sale or
transfer of assets or a purchase of assets for stock regardless of the number of
shares being issued. Further, no appraisal rights are available for shares of
any class or series listed on a national securities exchange or designated as a
national market system security on the Nasdaq Stock Market or held of record by
more than 2,000 stockholders, unless the agreement of merger or consolidation
converts such shares into anything other than:
 
     -  stock of the surviving corporation,
 
     -  stock of another corporation which is either listed on a national
        securities exchange or designated as a national market system security
        on the Nasdaq Stock Market or held of record by more than 2,000
        stockholders,
 
     -  cash in lieu of fractional shares, or
 
     -  some combination of the above.
 
                                       103
<PAGE>   117
 
OPPRESSION REMEDY
 
     The ABCA provides an oppression remedy that enables the court to make any
order, both interim and final, to rectify the matters complained of, if the
court is satisfied upon application by a complainant (as defined below) that:
(1) any act or omission of the corporation or an affiliate effects a result; (2)
the business or affairs of the corporation or an affiliate are or have been
carried on or conducted in a manner; or (3) the powers of the directors of the
corporation or of an affiliate are or have been exercised in a manner, that is
oppressive or unfairly prejudicial to or that unfairly disregards the interests
of any security holder, creditor, director or officer. A complainant includes:
 
     -  a present or former registered holder or beneficial owner of securities
        of a corporation or any of its affiliates;
 
     -  a present or former director or officer of the corporation or any of its
        affiliates; and
 
     -  any other person who in the discretion of the court is a proper person
        to make such application.
 
     Because of the breadth of the conduct which can be complained of and the
scope of the court's remedial powers, the oppression remedy is very flexible and
is sometimes relied upon to safeguard the interests of shareholders and other
complainants with a substantial interest in the corporation. Under the ABCA, it
is not necessary to prove that the directors of a corporation acted in bad faith
in order to seek an oppression remedy. Furthermore, the court may order the
corporation to pay the interim expenses of a complainant seeking an oppression
remedy, but the complainant may be held accountable for such interim costs on
final disposition of the complaint.
 
     The DGCL does not provide for a similar remedy.
 
DERIVATIVE ACTION
 
     Derivative actions may be brought in Delaware by a stockholder on behalf
of, and for the benefit of, the corporation. The DGCL provides that a
stockholder must aver in the complaint that he or she was a stockholder of the
corporation at the time of the transaction of which he or she complains. A
stockholder may not sue derivatively unless he or she first makes demand on the
corporation that it bring suit and such demand has been refused, unless it is
shown that such demand would have been futile.
 
     Under the ABCA, a complainant may apply to the court for leave to bring an
action in the name of and on behalf of a corporation or any subsidiary, or to
intervene in an existing action to which any such body corporate is a party, for
the purpose of prosecuting, defending or discontinuing the action on behalf of
the body corporate or subsidiary. Under the ABCA, no action may be brought and
no intervention in an action may be made unless the complainant has given
reasonable notice to the directors of the corporation or its subsidiary of the
complainant's intention to apply to the court and the court is satisfied that
(1) the directors of the corporation or its subsidiary will not bring,
diligently prosecute or defend or discontinue the action; (2) the complainant is
acting in good faith; and (3) it appears to be in the interests of the
corporation or its subsidiary that the action be brought, prosecuted, defended
or discontinued.
 
     Under the ABCA, the court in a derivative action may make any order it
thinks fit. Additionally, under the ABCA, a court may order a corporation or its
subsidiary to pay the complainant's reasonable legal fees.
 
SHAREHOLDER CONSENT IN LIEU OF MEETING
 
     Under the DGCL, unless otherwise provided in the certificate of
incorporation, any action required to be taken or which may be taken at an
annual or special meeting of stockholders may be taken without a meeting if a
consent in writing is signed by the holders of outstanding stock having not less
than the minimum number of votes that would be necessary to authorize such
action at a meeting at which all shares entitled to vote were present and voted.
The Veritas DGC Restated Certificate of Incorporation does not contain any
provision restricting action by written consent.
 
                                       104
<PAGE>   118
 
     Under the ABCA, shareholder action without a meeting may only be taken by
written resolution signed by all shareholders who would be entitled to vote
thereon at a meeting.
 
DIRECTOR QUALIFICATIONS
 
     At least half of the directors of an ABCA corporation generally must be
resident Canadians. The ABCA also requires that a corporation whose securities
are publicly traded must have not fewer than three directors, at least two of
whom are not officers or employees of the corporation or any of its affiliates.
The DGCL does not have comparable requirements.
 
FIDUCIARY DUTIES OF DIRECTORS
 
     Directors of corporations governed by the ABCA have fiduciary obligations
to the corporation. Directors of corporations incorporated or organized under
the DGCL have fiduciary obligations to the corporation and its shareholders.
Pursuant to these fiduciary obligations, the directors must act in accordance
with the so-called duties of "due care" and "loyalty". Under the DGCL, the duty
of care requires that the directors act in an informed and deliberative manner
and to inform themselves, prior to making a business decision, of all material
information reasonably available to them. The duty of loyalty is the duty to act
in good faith in a manner which the directors reasonably believe to be in the
best interests of the stockholders.
 
     Under the ABCA, the duty of loyalty requires directors of an Alberta
corporation to act honestly and in good faith with a view to the best interests
of the corporation, and the duty of care requires that the directors exercise
the care, diligence and skill that a reasonably prudent person would exercise in
comparable circumstances.
 
INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
     Under the ABCA, except in respect of an action by or on behalf of a
corporation or a body corporate to procure a judgment in its favor, a
corporation may indemnify a director or officer, a former director or officer or
a person who acts or acted at the corporation's request as a director or officer
of a body corporate of which the corporation is or was a shareholder or
creditor, and his or her heirs and legal representatives (an "Indemnifiable
Person"), against all costs, charges and expenses, including an amount paid to
settle an action or satisfy a judgment, reasonably incurred by him or her in
respect of any civil, criminal or administrative action or proceeding to which
he or she is made a party by reason of being or having been a director or
officer of such corporation or such body corporate, if: (1) he or she acted
honestly and in good faith with a view to the best interests of such
corporation; and (2) in the case of a criminal or administrative action or
proceeding that is enforced by a monetary penalty, he or she had reasonable
grounds for believing that his or her conduct was lawful. An Indemnifiable
Person is entitled to such indemnity from the corporation if he or she was
substantially successful on the merits in his or her defense of the action or
proceeding, fulfilled the conditions set out in (1) and (2), above and is fairly
and reasonably entitled to indemnity. A corporation may, with the approval of a
court, also indemnify an Indemnifiable Person in respect of an action by or on
behalf of the corporation or body corporate to procure a judgment in its favor,
to which such person is made a party by reason of being or having been a
director or an officer of the corporation or body corporate, if he or she
fulfills the conditions set out in (1) and (2), above. The Enertec Bylaws
provide for indemnification of directors and officers to the fullest extent
authorized by the ABCA.
 
     The DGCL provides that a corporation may indemnify its present and former
directors, officers, employees and agents (each, an "indemnitee") against all
reasonable expenses (including attorneys' fees) and, except in actions initiated
by or in the right of the corporation, against all judgments, fines and amounts
paid in settlement in actions brought against them, if such individual acted in
good faith and in a manner which he or she reasonably believed to be in, or not
opposed to, the best interests of the corporation and, in the case of a criminal
proceeding, had no reasonable cause to believe his or her conduct was unlawful.
The corporation shall indemnify an indemnitee to the extent that he or she is
successful on the merits or otherwise in the defense of any claim, issue or
matter associated with an action. The Veritas DGC Restated Certificate of
Incorporation provides for indemnification of directors and officers to the
fullest extent authorized by the DGCL.
 
                                       105
<PAGE>   119
 
     The DGCL allows for the advance payment of an indemnitee's expenses prior
to the final disposition of an action, provided that the indemnitee undertakes
to repay any such amount advanced if it is later determined that the indemnitee
is not entitled to indemnification with regard to the action for which the
expenses were advanced. Neither the ABCA nor the Enertec bylaws expressly
provide for such advance payment.
 
     Veritas DGC and Enertec have entered into indemnity agreements with each of
its directors and certain executive officers.
 
DIRECTOR LIABILITY
 
     The DGCL provides that the charter of a corporation may include a provision
which limits or eliminates the liability of directors to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
provided such liability does not arise from certain proscribed conduct,
including acts or omissions not in good faith or which involve intentional
misconduct or breach of the duty of loyalty. The Veritas DGC Restated
Certificate of Incorporation contains a provision limiting the liability of its
directors to the fullest extent permitted by the DGCL. The ABCA does not permit
any such limitation of a director's liability.
 
ANTI-TAKEOVER PROVISIONS AND INTERESTED STOCKHOLDER TRANSACTIONS
 
     The DGCL prohibits, in certain circumstances, a "business combination"
between the corporation and an "interested stockholder" within three years of
the stockholder becoming an "interested stockholder." An "interested
stockholder" is a holder who, directly or indirectly, controls 15% or more of
the outstanding voting stock or is an affiliate of the corporation and was the
owner of 15% or more of the outstanding voting stock at any time within the
prior three-year period. A "business combination" includes a merger,
consolidation, sale or other disposition of assets having an aggregate value in
excess of 10% of the consolidated assets of the corporation and certain
transactions that would increase the interested stockholder's proportionate
share ownership in the corporation. This provision does not apply where:
 
     -  the business combination or the transaction which resulted in the
        stockholder becoming an interested stockholder is approved by the
        corporation's board of directors prior to the time the interested
        stockholder acquired such 15% interest;
 
     -  upon the consummation of the transaction which resulted in the
        stockholder becoming an interested stockholder, the interested
        stockholder owned at least 85% of the outstanding voting stock of the
        corporation excluding, for the purpose of determining the number of
        shares outstanding, shares held by persons who are directors and also
        officers and by employee stock plans in which participants do not have
        the right to determine confidentially whether shares held subject to the
        plan will be tendered;
 
     -  the business combination is approved by a majority of the board of
        directors and the affirmative vote of two-thirds of the outstanding
        votes entitled to be cast by disinterested stockholders at an annual or
        special meeting;
 
     -  the corporation does not have a class of voting stock that is listed on
        a national securities exchange, authorized for quotation on an
        inter-dealer quotation system of the Nasdaq Stock Market, or held of
        record by more than 2,000 stockholders unless any of the foregoing
        results from action taken, directly or indirectly, by an interested
        stockholder or from a transaction in which a person becomes an
        interested stockholder;
 
     -  the corporation has opted out of this provision; or
 
     -  in certain other limited circumstances.
 
Veritas DGC has not opted out of this provision.
 
     The ABCA does not contain a comparable provision with respect to business
combinations. However, policies of certain Canadian securities regulatory
authorities, including Policy 9.1 of the Ontario Securities Commission ("Policy
9.1"), contain requirements in connection with related party transactions. A
related party transaction means, generally, any transaction by which an issuer,
directly or indirectly, acquires or transfers an
 
                                       106
<PAGE>   120
 
asset or acquires or issues treasury securities or assumes or transfers a
liability from or to, as the case may be, a related party by any means in any
one or any combination of transactions. "Related party" is defined in Policy 9.1
and includes directors, senior officers and holders of at least 10% of the
voting securities of the issuer.
 
     Policy 9.1 requires more detailed disclosure in the proxy material sent to
security holders in connection with a related party transaction, and, subject to
certain exceptions, the preparation of a formal valuation of the subject matter
of the related party transaction and any non-cash consideration offered therefor
and the inclusion of a summary of the valuation in the proxy material. Policy
9.1 also requires, subject to certain exceptions, that the minority shareholders
of the issuer separately approve the transaction, by either a simple majority or
two-thirds of the votes cast, depending on the circumstances.

               DISSENTING SHAREHOLDERS' AND OPTIONHOLDERS' RIGHTS
 
     Under the DGCL, holders of Veritas DGC Common Stock will not have appraisal
or dissenters' rights relating to the Transaction.
 
     THE FOLLOWING DESCRIPTION OF THE RIGHTS OF DISSENTING HOLDERS OF ENERTEC
COMMON SHARES, ENERTEC OPTIONS AND VESI EXCHANGEABLE SHARES IS NOT A
COMPREHENSIVE STATEMENT OF PROCEDURES TO BE FOLLOWED BY A DISSENTING SHAREHOLDER
OR OPTIONHOLDER WHO SEEKS PAYMENT OF THE FAIR VALUE OF HIS ENERTEC COMMON
SHARES, ENERTEC OPTIONS OR VESI EXCHANGEABLE SHARES AND IS QUALIFIED IN ITS
ENTIRETY BY THE REFERENCE TO THE FULL TEXT OF THE INTERIM ORDER AND SECTION 184
OF THE ABCA WHICH ARE ATTACHED TO THIS JOINT PROXY STATEMENT AS ANNEXES C AND I,
RESPECTIVELY. A SHAREHOLDER OR OPTIONHOLDER WHO INTENDS TO EXERCISE HIS RIGHT OF
DISSENT AND APPRAISAL SHOULD CAREFULLY CONSIDER AND COMPLY WITH THE PROVISIONS
OF SECTION 184 OF THE ABCA, AS MODIFIED BY THE INTERIM ORDER AND SHOULD SEEK HIS
OWN LEGAL ADVICE. FAILURE TO COMPLY WITH THE PROVISIONS OF SECTION 184 OF THE
ABCA, AS MODIFIED BY THE INTERIM ORDER AND TO ADHERE TO THE PROCEDURES
ESTABLISHED THEREIN MAY RESULT IN THE LOSS OF ALL RIGHTS THEREUNDER.
 
     The Court hearing the application for the Final Order has the discretion to
alter the rights of dissent described herein based on the evidence presented at
such hearing.
 
     Under the Interim Order, a holder of Enertec Common Shares or Enertec
Options is entitled, in addition to any other right he may have, to dissent and
to be paid by Enertec the fair value of the Enertec Common Shares or Enertec
Options held by him in respect of which he dissents, determined as of the close
of business on the last business day before the day on which the resolution from
which he dissents was adopted and a holder of VESI Exchangeable Shares is
entitled, in addition to any other right he may have, to dissent and to be paid
by VESI the fair value of the VESI Exchangeable Shares held by him in respect of
which he dissents, determined as of the close of business on the last business
day before the day on which the resolution from which he dissents was adopted. A
shareholder or optionholder may dissent only with respect to all of the shares
or options held by him or on behalf of any one beneficial owner and registered
in the dissenting shareholder's or optionholder's name. The demand for appraisal
must be executed by or for the holder of record, fully and correctly, as such
holder's name appears on the holder's share certificates or options. If the
shares are owned of record in a fiduciary capacity, such as by a trustee,
guardian or custodian, the demand should be made in that capacity, and if the
shares are owned of record by more than one person, as in a joint tenancy or a
tenancy in common, the demand should be made by or for all owners of record. An
authorized agent, including one or more joint owners, may execute the demand for
appraisal for a holder of record; however, such agent must identify the record
owner or owners and expressly identify the record owner or owners, and expressly
disclose in such demand that the agent is acting as agent for the record owner
or owners.
 
     PERSONS WHO ARE BENEFICIAL OWNERS OF ENERTEC COMMON SHARES OR VESI
EXCHANGEABLE SHARES REGISTERED IN THE NAME OF A BROKER, CUSTODIAN, NOMINEE OR
OTHER INTERMEDIARY WHO WISH TO DISSENT, SHOULD BE AWARE THAT ONLY THE REGISTERED
OWNER OF SUCH SHARES IS ENTITLED TO DISSENT. A REGISTERED HOLDER SUCH AS A
BROKER WHO HOLDS ENERTEC COMMON SHARES OR VESI EXCHANGEABLE SHARES AS NOMINEE
FOR BENEFICIAL OWNERS, SOME OF WHOM MAY DESIRE TO DEMAND APPRAISAL, MUST
EXERCISE DISSENT RIGHTS ON BEHALF OF SUCH BENEFICIAL OWNERS WITH RESPECT TO THE
SHARES HELD FOR SUCH BENEFICIAL OWNERS. IN SUCH CASE, THE DEMAND FOR APPRAISAL
SHOULD SET FORTH THE NUMBER OF ENERTEC COMMON SHARES OR VESI EXCHANGEABLE SHARES

     A dissenting holder of Enertec Common Shares or Enertec Options must send

objection must be received by the Secretary of Enertec in care of Fraser Milner,
30th Floor 237 - 4 Avenue S.W. Calgary, Alberta, T2P 4X7, Attention: David R.J.
Lefebvre, or the chairman of the Enertec meeting at or before the Enertec
meeting. An application may be made to the Court to fix the fair value of the
dissenting shareholder's Enertec Common Shares or optionholder's Enertec Options
after the Effective Date. If an application to the Court is made by either
Enertec or a dissenting shareholder or optionholder, Enertec must, unless the
Court otherwise orders, send to each dissenting shareholder or optionholder a
written offer to pay him an amount considered by the Enertec board to be the
fair value of the Enertec Common Shares or Enertec Options. The offer, unless
the Court otherwise orders, will be sent to each dissenting shareholder or
optionholder at least 10 days before the date on which the application is
returnable; if

Enertec is the applicant, or within 10 days after Enertec is served with notice
of the application, if a shareholder or optionholder is the applicant. The offer
will be made on the same terms to each dissenting holder of Enertec Common
Shares or Enertec Options and will be accompanied by a statement showing how the
fair value was determined.
 
     A dissenting holder of VESI Exchangeable Shares must send to VESI a written
objection to the Arrangement resolution, which written objection must be
received by the Secretary of VESI in care of Bennett Jones, 4500 Bankers Hall
East, 855 - 2nd Street S.W., Calgary, Alberta, T2P 4K7, Attention: Neil H.
Stevenson, or the chairman of the VESI meeting at or before the VESI meeting. An
application may be made to the Court to fix the fair value of the dissenting
shareholder's VESI Exchangeable Shares after the Effective Date. If an
application to the Court is made by either VESI or a dissenting shareholder,
VESI must, unless the Court otherwise orders, send to each dissenting
shareholder a written offer to pay him an amount considered by the VESI board to
be the fair value of the VESI Exchangeable Shares. The offer, unless the Court
otherwise orders, will be sent to each dissenting shareholder at least 10 days
before the date on which the application is returnable; if VESI is the
applicant, or within 10 days after VESI is served with notice of the
application, if a shareholder is the applicant. The offer will be made on the
same terms to each dissenting holder of VESI Exchangeable Shares and will be
accompanied by a statement showing how the fair value was determined.
 
     A dissenting holder of Enertec Common Shares or Enertec Options may make an
agreement with Enertec for the purchase of his Enertec Common Shares or Enertec
Options in the amount of Enertec's offer (or otherwise) at any time before the
Court pronounces an order fixing the fair value of the Enertec Common Shares or
Enertec Options. A dissenting shareholder or optionholder is not required to
give security for costs in respect of an application and, except in special
circumstances, will not be required to pay the costs of the application or
appraisal. On the application, the Court will make an order fixing the fair
value of the Enertec Common Shares of all dissenting shareholders or
optionholders who are parties to the application, giving judgment in that amount
against Enertec and in favor of each of those dissenting shareholders or
optionholders and fixing the time within which Enertec must pay that amount
payable to the dissenting shareholders or optionholders. The Court may in its
discretion allow a reasonable rate of interest on the amount payable to each
dissenting shareholder or optionholder calculated from the date on which the
shareholder or optionholder ceases to have any rights as a shareholder or
optionholder until the date of payment.
 
     A dissenting holder of VESI Exchangeable Shares may make an agreement with
VESI for the purchase of his VESI Exchangeable Shares in the amount of VESI's
offer (or otherwise) at any time before the Court pronounces an order fixing the
fair value of the VESI Exchangeable Shares. A dissenting holder of VESI
Exchangeable Shares is not required to give security for costs in respect of an
application and, except in special circumstances, will not be required to pay
the costs of the application or appraisal. On the application, the Court will
make an order fixing the fair value of the VESI Exchangeable Shares of all
dissenting holders thereof who are parties to the application, giving judgment
in that amount against VESI and in favor of each of those dissenting
shareholders and fixing the time within which VESI must pay that amount payable
to the dissenting shareholders. The Court may in its discretion allow a
reasonable rate of interest on the amount payable to each dissenting shareholder
calculated from the date on which the shareholder ceases to have any rights as a
shareholder until the date of payment.

between Enertec and the dissenting holder of Enertec Common Shares or Enertec
Options as to the payment to be made by Enertec to the dissenting shareholder or
optionholder, or upon the pronouncement of a Court order, whichever first
occurs, the dissenting shareholder or optionholder will cease to have any rights
as a shareholder or optionholder other than the right to be paid the fair value
of the Enertec Common Shares or Enertec Options in the amount agreed to between
Enertec and the dissenting shareholder or optionholder or in the amount of the
judgment, as the case may be. Until one of these events occurs, the shareholder
or optionholder may withdraw his dissent, or Enertec may rescind the Arrangement
resolution and in either event, the dissent and appraisal proceedings in respect
of that shareholder or optionholder will be discontinued.

     THE COMBINATION AGREEMENT PROVIDES THAT IT IS A CONDITION TO THE

OF DISSENT AS DESCRIBED ABOVE.

                     PROPOSED VERITAS DGC CHARTER AMENDMENT
 
BACKGROUND AND REASONS
 
     In August 1996, Digicon Inc. (now known as Veritas DGC) completed a
combination with VESI. As part of that combination, Veritas DGC completed a
recapitalization plan which resulted in the adoption of a Restated Certificate
of Incorporation. Among other things, the Restated Certificate of Incorporation
authorized 40,000,000 ordinary shares, consisting of one share of special voting
stock (the "VESI Special Voting Stock"), with all other ordinary shares being
designated as common stock, and 1,000,000 shares of preferred stock. The VESI
Special Voting Stock was issued in connection with the combination to provide a
mechanism for the holders of VESI Exchangeable Shares to vote as if the shares
had been exchanged for Veritas DGC Common Stock.
 
     As a condition to the closing of the Combination Agreement, the Veritas DGC
Restated Certificate of Incorporation must be amended to (a) designate a new
series of special voting stock ("ERS Special Voting Stock") which will provide
the mechanism for the holders of VESI Series 1 Exchangeable Shares to vote as if
the shares had been exchanged for Veritas DGC Common Stock and (b) delete a
restriction which prohibits the Veritas DGC board from designating a new series
of ordinary shares, such as the ERS Special Voting Stock, without the unanimous
approval of all outstanding ordinary shares.
 
AMENDMENTS
 
     Designation of ERS Special Voting Stock.  The Charter Amendment provides
for a new series of Veritas DGC ordinary shares designated "ERS Special Voting
Stock." The designation of the series is set forth as follows:
 
        Section 4.B.  ERS Special Voting Stock Designated. A series of
        ordinary shares, consisting of one such share, is hereby
        designated as "ERS Special Voting Stock" (hereinafter referred
        to as "ERS Special Voting Stock"). Each outstanding share of
        ERS Special Voting Stock shall be entitled at any relevant date
        to the number of votes determined in accordance with the "Plan
        of Arrangement" (as that term is defined in that certain
        "Combination Agreement" dated as of March 30, 1999 (hereinafter
        referred to as the "ERS Combination Agreement") by and between
        Veritas DGC, Veritas Energy Services Inc. and Enertec Resource
        Services Inc. ("ERS")) on all matters presented to the
        stockholders. No dividend or distribution of assets shall be
        paid to the holders of ERS Special Voting Stock. The ERS
        Special Voting Stock is not convertible into any other class or
        series of the capital stock of the Corporation or into cash,
        property or other rights, and may not be redeemed. Any shares
        of ERS Special Voting Stock purchased or otherwise acquired by
        the Corporation shall be deemed retired and shall be canceled
        and may not thereafter be reissued or otherwise disposed of by
        the Corporation. So long as any "ERS Exchangeable Shares"
        (i.e., "Series 1 Exchangeable Shares," as that term is defined
        in the ERS Combination Agreement) shall be outstanding, the
        number of shares comprising the ERS Special Voting Stock shall
        not be increased or decreased and no other term of the ERS
        Special Voting Stock shall be amended, except upon the
        unanimous approval of all outstanding ordinary shares.
 
     The one share of ERS Special Voting Stock will be deposited with the
Trustee pursuant to the Voting and Exchange Trust Agreement. The Trustee will
have the right to vote the Series 1 Exchangeable Shares pursuant to that
agreement. See, "The Companies After the Transaction -- Voting and Exchange
Trust Agreement."
 
     Deletion of Restriction on Designation of Additional Series of Ordinary
Shares.  The Charter Amendment also provides for the deletion of Section 3(c) of
the Veritas DGC Restated Certificate of Incorporation, which is set forth below:
 
        no series of ordinary shares (except for such series as are
        herein designated and except for any increase in the number of
        shares constituting such a series) shall be designated by
        resolution of the Board of Directors except upon the unanimous
        approval of all outstanding ordinary shares.
                                       111
<PAGE>   125
 
     This provision effectively restricts the Veritas DGC board from completing
a transaction such as contemplated by the Combination Agreement without seeking
approval of the holders of Veritas DGC Common Stock, even in the absence of any
requirement to do so by the DGCL, the SEC or any stock exchange. By eliminating
this restriction, Veritas DGC will be able to complete transactions, similar to
that proposed by the Combination Agreement, without seeking approval of the
holders of Veritas DGC Common Stock. This will result in additional flexibility
for Veritas DGC to complete similar "exchangeable share" transactions, in the
absence of legal or regulatory requirements, on an expeditious basis and to
benefit from significant cost savings by eliminating the need to seek
stockholder approval. Except for the Arrangement, Veritas DGC does not have any
pending or proposed transactions of the type which would require stockholder
approval under the restriction which is proposed to be deleted.
 
     The Charter Amendment also contains amendments to provisions to reflect
definitional changes required by the other amendments.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
  Veritas DGC Inc.
 
     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of income, of changes in stockholders' equity
and of cash flows present fairly, in all material respects, the financial
position of Veritas DGC Inc. and its subsidiaries at July 31, 1998 and 1997 and
the results of their operations and their cash flows for the years then ended in
conformity with generally accepted accounting principles. 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 of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders of
  Veritas DGC Inc.
 
     We have audited the consolidated statements of income, cash flows and
changes in stockholders' equity of Veritas DGC Inc. and subsidiaries for the
year ended July 31, 1996. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on the consolidated financial statements based on our audit. The
consolidated financial statements give retroactive effect to the merger of
Digicon Inc. and Veritas Energy Services Inc., which has been accounted for as a
pooling of interests as described in Note 2 to the consolidated financial
statements. We did not audit the consolidated statements of income, cash flows
and changes in stockholders' equity of Veritas Energy Services Inc. for the year
ended October 31, 1995 or for the twelve months ended July 31, 1996, which
statements reflect total revenues of $109,996,000 for the year ended October 31,
1995 and $118,591,000 for the twelve months ended July 31, 1996. Those
statements were audited by other auditors whose report has been furnished to us,
and our opinion, insofar as it relates to the amounts included for Veritas
Energy Services Inc. for 1995 and 1996, is based solely on the report of such
other auditors.
 
     We conducted our audit in accordance with generally accepted auditing
standards. These 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 audit and the report of the other auditors provide a
reasonable basis for our opinion.
 
     In our opinion, based on our audit and the report of the other auditors,
the consolidated financial statements referred to above present fairly, in all
material respects, the results of operations of Veritas DGC Inc. and
subsidiaries and its cash flows for the year ended July 31, 1996 in conformity
with generally accepted accounting principles.

in its financial position for the nine months ended July 31, 1996 and for the
year ended October 31, 1995 in accordance with Canadian generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                FOR THE YEARS ENDED JULY 31, 1996, 1997 AND 1998
        AND UNAUDITED FOR THE SIX MONTHS ENDED JANUARY 31, 1998 AND 1999
 
1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
CONSOLIDATION
 
     Veritas DGC Inc. (the "Company") provides seismic data acquisition, data
processing, multi-client data sales and exploration and development information
services to the petroleum industry in selected markets worldwide. The
accompanying consolidated financial statements include the accounts of Veritas
DGC Inc., formerly Digicon Inc. ("Digicon"), and all majority-owned domestic and
foreign subsidiaries. Investments in 50% or less-owned companies and joint
ventures are accounted for on the equity method. All material intercompany
balances and transactions have been eliminated. All financial information for
all periods presented prior to the merger on August 30, 1996 between Digicon and
Veritas Energy Services Inc. ("VES") includes the results of VES. (See Note 2.)
The merger has been accounted for as a pooling of interests. Digicon effected a
quasi-reorganization adjustment as of July 31, 1991 in which its accumulated
deficit at July 31, 1991 of $139,751,000 was offset against additional paid-in
capital.
 
INTERIM FINANCIAL INFORMATION
 
     The interim financial information for the six month periods ended January
31, 1998 and 1999 are unaudited, but reflect all adjustments that, in the
opinion of management, are necessary to provide a fair presentation of the
financial position, results of operations and cash flows for the dates and
periods covered. All such adjustments are of a normal recurring nature. Interim
period results are not necessarily indicative of results of operations or cash
flows for a full year period.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
RECLASSIFICATION OF PRIOR YEAR BALANCES
 
     Certain prior year balances have been reclassified for consistent
presentation.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The Company's financial instruments include cash and short-term
investments, restricted cash investments, accounts and notes receivable,
accounts payable and debt. The fair market value of the $75.0 million senior
notes included in long-term debt and $2.2 million of related accrued interest is
$78.5 million based on the present value of total payments due at the high yield
corporate bond rate at July 31, 1998. The carrying value is a reasonable
estimate of fair value for all other instruments.
 
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 annual and
interim 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

                       VERITAS DGC INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                FOR THE YEARS ENDED JULY 31, 1996, 1997 AND 1998
        AND UNAUDITED FOR THE SIX MONTHS ENDED JANUARY 31, 1998 AND 1999
 
separate component in the stockholders' equity section of the consolidated
balance sheet. Classifications included in the accumulated balance are disclosed
on the face of the consolidated balance sheet or 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.
 
     In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
about Pensions and Other Postretirement Benefits," which will supersede the
disclosure requirements of SFAS No. 87, "Employers' Accounting for Pensions,"
SFAS No. 88, "Employers' Accounting for Settlements and Curtailments of Defined
Benefit Pension Plans and for Termination Benefits," and SFAS No. 106,
"Employers' Accounting for Postretirement Benefits Other Than Pensions." This
statement addresses disclosures only and will require the Company to provide a
reconciliation of the beginning and ending balances of the benefit obligation
and the fair value of plan assets in addition to disclosures already presented.
The Company will be required to implement this statement during the fourth
quarter of fiscal year 1999.
 
     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This standard requires companies to record
derivative financial instruments on the balance sheet as assets or liabilities,
as appropriate, at fair value. Gains or losses resulting from changes in the
fair values of those derivatives are accounted for depending on the use of the
derivative and whether it qualifies for hedge accounting. The Company will be
required to implement this statement in fiscal year 2000. The Company believes
that the implementation of this standard will not have a material adverse effect
on the Company's consolidated financial position, results of operations or
liquidity.
 
TRANSLATION OF FOREIGN CURRENCIES
 
     The Company has determined that the United States ("U.S.") dollar is its
primary functional currency and, accordingly, most foreign entities translate
property and equipment (and related depreciation) and inventories into U.S.
dollars at the exchange rate in effect at the time of their acquisition while
other assets and liabilities are translated at year-end rates. Operating results
(other than depreciation) are translated at the average rates of exchange
prevailing during the year. The remaining foreign entities use the Canadian
dollar as their functional currency and translate all assets and liabilities at
year-end exchange rates and operating results at average exchange rates
prevailing during the year. Adjustments resulting from the translation of assets
and liabilities are recorded in the cumulative foreign currency translation
adjustment account in stockholders' equity. Remeasurement gains and losses are
included in the determination of net income and are reflected in other costs and
expenses. (See Note 13.)

                FOR THE YEARS ENDED JULY 31, 1996, 1997 AND 1998
        AND UNAUDITED FOR THE SIX MONTHS ENDED JANUARY 31, 1998 AND 1999
 
CASH EQUIVALENTS
 
     For purposes of the Consolidated Statements of Cash Flows, the Company has
defined "cash equivalents" as items readily convertible into known amounts of
cash with original maturities of three months or less.
 
RESTRICTED CASH INVESTMENTS
 
     Restricted cash investments in the amounts of $550,000 and $186,000 at July
31, 1997 and 1998, respectively, were pledged as collateral on certain bank
guarantees related to contracts entered into in the normal course of business.
 
ACCOUNTS RECEIVABLE
 
     Included in accounts and notes receivable at July 31, 1997 and 1998 are
unbilled amounts of approximately $17,308,000 and $43,058,000, respectively.
Such amounts are either not billable to the customer at July 31 in accordance
with the provisions of the contract and generally will be billed in one to four
months or are currently billable and will be invoiced in the next monthly
statement cycle.
 
INVENTORIES
 
     Inventories of materials and supplies are stated at the lower of average
cost or market.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are recorded at cost. Depreciation is computed using
the straight-line method based on estimated useful lives as follows:

                                                                  USEFUL LIFE

</TABLE>
 
     Expenditures for routine repairs and maintenance are charged to expense as
incurred; expenditures for additions and improvements, including capitalized
interest, are capitalized and depreciated over the estimated useful life of the
related asset. The net gain or loss on property and equipment disposed of is
included in other costs and expenses. (See Note 13.)
 
     In fiscal 1996, the Company recognized impairment of assets in the amount
of $3,628,000 or $.20 per common share and per common share -- assuming
dilution. (See Note 12.)
 
MULTI-CLIENT DATA LIBRARY
 
     The Company collects and processes certain seismic data for its own account
to which it retains all ownership rights and which it resells to clients on a
non-transferable, non-exclusive basis. The Company may obtain precommitted sales
contracts to help fund the cash requirements of these surveys which generally
last from five to seven months. The Company capitalizes associated costs using
an estimated sales method. Under that method the amount capitalized equals
actual costs incurred less costs attributed to the precommitted sales contracts
based on the percentage of total estimated costs to total estimated sales
multiplied by actual sales. The capitalized cost of multi-client data library is
likewise charged to operations in the period subsequent sales occur

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                FOR THE YEARS ENDED JULY 31, 1996, 1997 AND 1998
        AND UNAUDITED FOR THE SIX MONTHS ENDED JANUARY 31, 1998 AND 1999
 
based on the percentage of total estimated costs to total estimated sales
multiplied by actual sales. Beginning in fiscal 1997, the Company changed the
estimated life of its multi-client data library so that any costs remaining 24
months after completion of a survey are charged to operations over a period not
to exceed 24 months. The Company periodically reviews the carrying value of the
multi-client data library to assess whether there has been a permanent
impairment of value and records losses when the total estimated costs exceed
total estimated sales or when it is determined that estimated sales would not be
sufficient to cover the carrying value of the asset.
 
GOODWILL
 
     The Company records the purchase price of businesses or joint venture
interests in excess of the fair value of net assets acquired as goodwill which
is amortized using the straight-line method over a period of 10 to 20 years
which approximates the period benefits are expected to be derived. The Company
periodically reviews the carrying value of goodwill in relation to the current
and expected operating results of the businesses or joint ventures in order to
assess whether there has been a permanent impairment of such amounts.
 
MOBILIZATION COST
 
     Transportation and make-ready expenses of seismic operations incurred prior
to commencement of business in an area, that would not have been incurred
otherwise, are deferred and amortized over the lesser of the term of the related
contract or backlog of contracts in that area or one year. Amounts applicable to
operations for the Company's own account are included in the cost of the
multi-client data library. There were no unamortized mobilization costs at July
31, 1997. Unamortized mobilization costs are shown as other assets and totaled
$818,000 at July 31, 1998.
 
LEASES
 
     Operating leases include those for office space, specialized seismic
equipment rented for short periods of time, and the Company's seismic ships
which generally are chartered on a short-term basis.
 
REVENUES
 
     Revenues from data acquisition and data processing services are recognized
on the percentage-of-completion method measured by the amount of data collected
or processed to the total amount of data to be collected or processed or by time
incurred to total time expected to be incurred. Sales from the licensing of
multi-client data surveys are recognized upon delivery of such data based upon
agreed rates set forth in the contract.
 
RESEARCH AND DEVELOPMENT
 
     Research and development costs are charged to expense when incurred.
Research and development costs for the years ended July 31, 1996, 1997 and 1998
were $3,193,000, $3,725,000 and $6,196,000, respectively.
 
STOCK-BASED COMPENSATION
 
     The Company maintains stock-based compensation plans that are accounted for
using the intrinsic value based method allowed by Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees," and related
Interpretations. Under that method, compensation expense is recorded in the
accompanying consolidated financial statements when the quoted market price of
stock at the grant date or other measurement date exceeds the amount an employee
must pay to acquire the stock. As required by SFAS No. 123, "Accounting for
Stock-Based Compensation," the effect on net income and earnings per share of
compensation

expense that would have been recorded using the fair value based method is
reported through disclosure. (See Note 9.)
 
EARNINGS PER SHARE
 
     All per share amounts contained herein have been restated in accordance
with SFAS No. 128, "Earnings per Share," which became effective for interim and
annual reporting periods ending after December 15, 1997. This statement requires
the computation of earnings per share based upon weighted average common shares
outstanding and earnings per share -- assuming dilution based upon weighted
average common shares outstanding and additional common shares, utilizing the
treasury stock method and average market prices, that would have been
outstanding if dilutive potential common shares had been issued. (See Note 14.)
 
2.   BUSINESS COMBINATION
 
     On August 30, 1996, Digicon and VES consummated a business combination (the
"Combination"). VES became a wholly owned subsidiary of Digicon and Digicon
changed its name to Veritas DGC Inc. As a result of the Combination, each share
of VES no par value common shares outstanding was converted into the right to
receive VES no par value exchangeable stock (the "Exchangeable Stock") at an
exchange ratio of 0.8 of a share of Exchangeable Stock per VES common share. All
of the holders of VES common shares, except for those shareholders who perfected
and properly exercised their right to dissent from the Combination and received
fair value of their shares in cash, became holders of Exchangeable Stock and
accordingly, 7,023,701 shares of Exchangeable Stock were issued. The aggregate
stated capital of the Exchangeable Stock is equal to the aggregate stated
capital immediately prior to the Combination of the VES common shares that were
exchanged or approximately $30.0 million. The Exchangeable Stock is convertible,
at the discretion of the stockholder, on a one-for-one basis into shares of the
Company's $0.01 par value common stock and their holders have rights identical
to the holders of the Company's common stock. Options to purchase shares of VES
common stock ("VES Option") were converted into options to purchase shares of
the Company's common stock at an exchange ratio of 0.8 of an option in the
Company's common stock per VES Option. (See Note 9.) The VES articles of
amalgamation were amended to reduce the number of authorized VES common shares
to one which is held by the Company.
 
     The Combination has been accounted for as a pooling of interests and,
accordingly, the accompanying consolidated financial statements have been
prepared on a basis that includes the accounts of Digicon and VES. Information
concerning common stock and per share data has been restated on an equivalent
share basis. As a result of the differing year ends of Digicon and VES, results
of operations for dissimilar year ends have been combined. Digicon's results of
operations for the year ended July 31, 1995 have been combined with VES' results
of operations for the year ended October 31, 1995. To conform year ends,
Digicon's results of operations for the year ended July 31, 1996 have been
combined with VES' results of operations for the twelve months ended July 31,
1996 and, accordingly, VES' operating results for the period August 1, 1995
through October 31, 1995 are included in the years ended July 31, 1995 and July
31, 1996. An adjustment in an amount equal to the results of operations for this
three-month period is included in the consolidated statements of changes in
stockholders' equity. VES' revenues, net income, and earnings per share and
earnings per share -- assuming dilution were $22,150,000, $936,000 and $0.05,
respectively, for the period August 1, 1995 through October 31, 1995.

        AND UNAUDITED FOR THE SIX MONTHS ENDED JANUARY 31, 1998 AND 1999
 
     Presented below is the effect of the pooling of interests on previously
reported results of operations for the year ended July 31, 1996. Amounts related
to VES have been converted into the Company's reporting currency, U.S. dollars,
using weighted average exchange rates prevailing during the period and reflect
adjustments for differences between U.S. and Canadian generally accepted
accounting principles ("GAAP") and reclassifications to conform financial
statement presentation. Canadian to U.S. GAAP adjustments include adjustments to
(i) write off foreign exchange losses on borrowings which are deferred and
amortized over the period of the debt, decreasing net income by approximately
$173,000 and (ii) reverse the effect of a prior period adjustment, increasing
net income by approximately $102,000. Reclassification of $28,842,000 has been
made to net amounts billed to customers for reimbursable costs against VES'
revenues.

     There were no material adjustments to the net assets of VES as a result of
adopting the same accounting principles as the Company.
 
     During the year ended July 31, 1996 and 1997, the Company incurred and
expensed $3,666,000 and $597,000, respectively, of costs associated with the
Combination. These costs consist primarily of professional fees and include
$150,000 payable to a stockholder who was the former Chairman of the Board of
Directors for consulting services rendered in conjunction with the Combination.

     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.
 
     In October 1998, the Company issued an additional $60.0 million of senior
notes at 9 3/4% due in October 2003. In connection with the issuance of the
senior notes, the amount the Company may redeem in aggregate principal amount
prior to October 15, 1999 increased to $35.0 million.
 
     The Company maintained a revolving credit agreement which matured in July
1998 with a commercial bank that provided advances up to $25.0 million of which
$20.0 million were secured by substantially all of the receivables of the
Company. Advances bore interest, at the Company's election, at LIBOR plus two
percent or prime rate and were defined by a borrowing formula. In July 1998, the
Company obtained a new revolving credit agreement due July 2001 with commercial
lenders to provide advances up to $50.0 million. Advances are limited by an
unsecured borrowing base and bear interest, at the Company's election, at LIBOR
or prime rate (8 1/2% at July 31, 1998 and 7 3/4% at January 31, 1999) plus a
margin based on certain ratios maintained by the Company. Covenants in the
agreement limit, among other things, the Company's right to take certain
actions, including creating indebtedness. In addition, the agreement requires
the Company to maintain certain financial ratios. No advances were outstanding
at July 31, 1997 and 1998 and January 31, 1999 under the credit agreements.
 
     The Company's equipment purchase obligations represent installment loans
and capitalized lease obligations primarily related to computer and seismic
equipment.

     A valuation allowance is established when it is more likely than not that
some portion or all of the deferred tax assets will not be realized. The
valuation allowance is then adjusted when the realization of deferred tax assets
becomes more likely than not. Adjustments are also made to recognize the
expiration of net operating loss and investment tax credit carryforwards, with
equal and offsetting adjustments to the related deferred tax asset. Should the
Company's income projections result in the conclusion that realization of
additional deferred tax assets is more likely than not, further adjustments to
the valuation allowance are made. Since the Company's quasi-reorganization with
respect to Digicon on July 31, 1991 the tax benefits of net operating loss

direct addition to paid-in capital, when realization is more likely than not.
The net reduction of approximately $1,679,000 in the valuation allowance during
the current period resulted primarily from recognition of the expected
utilization of net operating loss carryforwards generated prior to the
quasi-reorganization and the expiration of investment tax credits.
 
     As of July 31, 1998, the Company has U.S. net operating loss carryforwards
of approximately $77,964,000 and investment tax credit carryforwards of
approximately $334,000. Approximately $53,421,000 of net operating loss
carryforwards and all of the investment tax credit carryforwards existed prior
to the quasi-reorganization. The following schedule sets forth the expiration
dates of the U.S. net operating loss and investment tax credit carryforwards:

     Internal Revenue Service regulations restrict the utilization of U.S. net
operating loss carryforwards and other tax benefits (such as investment tax
credits) for any company in which an "ownership change" (as defined in Section
382 of the Internal Revenue Code) has occurred. The Company has performed the
required testing and has concluded that two "ownership changes" have occurred.
The first occurred in connection with the issuance of common stock through a
public offering made by the Company on January 6, 1992. The utilization of U.S.
net operating loss carryforwards existing at the date of the first "ownership
change" is limited to approximately $4,041,000 per year. The second "ownership
change" occurred on August 30, 1996 as a result of the stock acquisition of
Veritas Energy Services Inc. The utilization of U.S. net operating losses
incurred between the first and second ownership changes is limited to
approximately $8,875,000 per year, which includes the limitation of
approximately $4,041,000 from the first ownership change. The second limitation
also applies to the limitation from the first ownership change that accumulated
during the periods between the first and second ownership changes. During the
years ended July 31, 1997 and 1998, the Company utilized approximately
$10,983,000 and $8,875,000 of limitation carryover, respectively. As of July 31,
1998, approximately $11,492,000 of unused limitation carryover remained.
 
     Foreign operations had net operating loss carryforwards of approximately
$25,187,000 at July 31, 1998, of which approximately $14,385,000 existed prior
to the quasi-reorganization. Approximately $16,677,000 of the total foreign net
operating loss carryforwards are related to United Kingdom operations, have an
indefinite carryforward period, and are available to offset future profits in
the Company's current trade or business. Approximately $13,312,000 of the United
Kingdom net operating loss carryforwards existed prior to the

quasi-reorganization. Approximately $4,186,000 of the total foreign net
operating loss carryforwards are related to Oman operations, were generated
after the quasi-reorganization and have a carryforward period of five years.
 
     The Company considers the undistributed earnings of its foreign
subsidiaries to be permanently reinvested. The Company has not provided deferred
U.S. income tax on those earnings, as it is not practicable to estimate the
amount of additional tax that might be payable should these earnings be remitted
or deemed remitted as dividends or if the Company should sell its stock in the
subsidiaries.
 
7.   DEFERRED CREDITS
 
     In August 1992, the Company entered into agreements with a customer
pursuant to which the Company received certain seismic equipment with a fair
value of approximately $1,792,000 and was obligated to allow $7,800,000 in
discounts at specified rates on future seismic services performed by the Company
for such customer. The Company recorded deferred revenue equal to the fair value
of seismic equipment at the time the equipment was received. The deferred
revenue is amortized as an adjustment to revenues at a rate determined by the
ratio of revenues generated by the customer during a reporting period to total
revenues estimated to be generated by the customer under the agreements.
Revenues are recognized net of discounts allowed as the customer purchases
seismic services eligible for the discounts. At July 31, 1998, there was no
remaining unrecognized deferred revenue and remaining discounts in the amount of
$1,847,000 were available to such customer.
 
     The Company also has $5,022,000 and $585,000 at July 31, 1997 and 1998,
respectively, included in accounts payable-trade relating to deferred credits
earned by certain customers in conjunction with their original participation in
certain of the Company's multi-client data surveys. These credits may be applied
by the customers against future invoiced amounts.
 
8.   COMMITMENTS AND CONTINGENT LIABILITIES
 
     Total rentals of vessels, equipment and office facilities charged to
operations amounted to $28,210,000, $37,332,000 and $57,476,000 for the years
ended July 31, 1996, 1997 and 1998, respectively.

Company has commitments of approximately $3,000,000 outstanding at July 31,

     On November 25, 1997, the Company entered into a 96-month charter agreement
for a vessel which is being constructed by a shipbuilder for the owner. The
charter is noncancellable unless the owner exercises its right to cancel the
shipbuilding contract due to late delivery (in excess of 180 days of the
scheduled delivery time of May 1999).

     The Company has an employment agreement with a former employee, who was
also a director, that contains a non-compete clause for a period of three years
ending December 31, 1998 during which time the former employee will receive
payments of $12,709 per month plus certain employee benefits.
 
     During 1993 the Company purchased occurrence-based workers compensation
insurance. The policies for the years ended August 31, 1997 and 1998 were issued
under a guaranteed cost program and, accordingly, there were no deductibles. The
policy for the year ended August 31, 1996 provided for a maximum deductible of
$1,000,000. Management has evaluated the adequacy of the accrual for the
liability for incurred but unreported workers compensation claims and has
determined that the ultimate resolution of any such claims would not have a
material adverse impact on the financial position of the Company.
 
     The Company has letters of credit in the amount of $4,150,000 at July
31,1998 that will expire upon the completion of certain events relating to
specific contracts.
 
9.   EMPLOYEE BENEFITS
 
     The Company maintains a 401(k) plan in which employees of the Company's
majority-owned domestic subsidiaries and certain foreign subsidiaries are
eligible to participate. However, employees of foreign subsidiaries who are
covered under a foreign deferred compensation plan are not eligible. Employees
are permitted to make contributions of up to 10% of their salary to a maximum of
$9,500 per year. Generally, the Company will contribute an amount equal to
one-half of the employee's contribution of up to $8,000 or 8% of the employee's
salary (whichever is less); however, if consolidated pre-tax income for any
fiscal year is less than the amount required to be contributed by the Company,
the Company may elect to reduce its contribution, but in no event may it reduce
the total contribution to less than 25% of the employee contribution. The
Company may make additional contributions from its current or cumulative net
profits in an amount to be determined by the Board of Directors. The Company's
matching contributions to the 401(k) plan were $314,000 in 1996, $426,000 in
1997, and $679,000 in 1998.
 
     The Company has an employee nonqualified stock option plan under which
options are granted to officers and key employees. Options generally vest over a
period of time and are exercisable over a ten-year period but may not be
exercised earlier than six months after the grant date. The exercise price for
each option shall not be less than the lesser of (i) the fair market value of
the common stock on the grant date or (ii) the average fair market value of the
common stock during the 30 trading days ending on the trading day next preceding
the grant date. At July 31, 1998 the Company had authorized 1,158,333 shares of
common stock to be issued under the plan. In March 1999, the Company amended and
restated its employee non-qualified stock option plan to increase the number of
authorized common shares that may be issued under the plan to 3,954,550 shares.
 
     The Company also has a stock option plan for non-employee directors (the
"Director Plan") under which options are granted to non-employee directors of
the Company. The Director Plan provides that every year each eligible director
shall be granted options to purchase 10,000 shares of the Company's common
stock. Options vest ratably over four years on the anniversary of the grant date
and are exercisable over ten years. The exercise price for each option granted
is fair market value, as defined. The Company has authorized 600,000 shares of
common stock to be issued under the Director Plan.
 
     In December 1998, the Company amended and restated its non-employee
director stock option plan. Options to purchase 5,000 shares will be granted
every year and will vest 25% on the grant date and 25% on each anniversary over
the following three years. All other major provisions remain the same.

     At the date of Combination (see Note 2), options to purchase VES Common
Stock ("VES Option") were converted into options to purchase shares of the
Company's common stock at an exchange ratio of 0.8 of an option in the Company's

at varying times through November 2005.

     In conjunction with certain employment agreements, the Company issued
10,000 and 13,025 shares of restricted stock with weighted average grant date
fair values of $20.25 and $33.66 per share, respectively, during the years ended
July 31, 1997 and 1998, respectively, to certain individuals in exchange for
services rendered over a three-year period.
 
     On November 1, 1997, the Company initiated a compensatory employee stock
purchase plan for up to 500,000 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. The participant's option to purchase common stock is 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. During the year ended July 31, 1998, 52,731 shares of
common stock were issued with a weighted average grant date fair value of $35.37
per share.
 
     On June 9, 1998, the Company initiated a restricted stock plan for up to
50,000 shares. The eligibility of an employee and the terms and amount of the
grant are determined by the Board of Directors' Compensation Committee. During
the year ended July 31, 1998, 4,400 shares of restricted stock were issued at a
weighted average grant date fair value of $43.09 per share which will vest over
a three-year period.

     The Company maintains a contributory defined benefit pension plan (the
"Pension Plan") for eligible participating employees in the United Kingdom
offices. Monthly contributions by employees are equal to 4% of their salaries
with the Company providing an additional contribution in an actuarially
determined amount necessary to fund future benefits to be provided under the
Pension Plan. Benefits provided are based upon 1/60 of the employee's final
pensionable salary (as defined) for each complete year of service up to 2/3 of
the employee's final pensionable salary and increase annually at 5%. The Pension
Plan also provides for 50% of such actual or expected benefits to be paid to a
surviving spouse upon the death of a participant. Pension Plan assets consist
mainly of investments in marketable securities which are held and managed by an
independent trustee. The net periodic pension costs are as follows:

10. COMMON AND PREFERRED STOCK
 
     The board of directors of the Company, without any action by the
stockholders, may issue up to one million shares of authorized preferred stock,
par value, $.01, in one or more series and determine the voting rights,
preferences as to dividends and in liquidation and the conversion and other
rights of such stock. There are no shares of preferred stock outstanding as of
July 31, 1998.
 
     On May 27, 1997, the board of directors of the Company declared a
distribution of one right for each outstanding share of common stock or
Exchangeable Stock (see Note 2) to shareholders of record at the close of
business on June 12, 1997 and designated 400,000 shares of the authorized
preferred stock as a class to be distributed under a shareholder rights
agreement. Upon the occurrence of certain events enumerated by the shareholder
rights agreement, each right entitles the registered holder to purchase a
fraction of a share of the Company's authorized preferred stock or the common
stock of an acquiring company. The rights, among other things, will cause
substantial dilution to a person or group that attempts to acquire the Company.
The rights expire on May 15, 2007 but may be redeemed earlier.
 
     In July 1998, the board of directors approved a stock repurchase program
under which the Company is authorized to buy up to 1,000,000 shares of its
outstanding common stock in open market transactions. At July 31, 1998, the
Company had repurchased 50,000 shares at $34.50 per share.

11. WARRANTS
 
     In conjunction with the cancellation of a previous issue of common and
preferred stock and certain other liabilities, the Company authorized 454,545
warrants which may be exercised for 454,545 shares of common stock. The warrants
were issued for a term of five years beginning July 5, 1991 at an exercise price
of $18.00 per share. The warrants could only be exercised for cash. Warrants for
29,433 shares were exercised on July 5, 1996 and the remaining warrants expired.
 
     In conjunction with a previously outstanding secured term loan, the Company
issued 113,333 warrants exercisable at a price of $6.00 per share. The warrants
were exercised in December 1996.
 
     In conjunction with previously outstanding short-term related party loans,
the Company issued warrants to purchase 120,000 common shares for cash at a
price of $4.50 per share to the lenders. As of July 31, 1998, all warrants have
been exercised.
 
12. WRITE-OFF/WRITE-DOWN OF ASSETS
 
     In connection with the Combination, management committed the Company to a
plan to upgrade its seismic data processing hardware. Certain equipment was
scheduled to be replaced by October 1996. During July 1996, the Company
recognized impairment of $3,628,000 relating to the abandonment of the equipment
to be replaced.

19. SUBSEQUENT EVENT (UNAUDITED)
 
     On March 30, 1999, the Company signed a definitive combination agreement
(the "Agreement") with Enertec Resource Services Inc. ("Enertec") and VES.
Consummation of the Agreement is subject to a number of conditions, including
regulatory clearances in Canada and the United States, judicial clearance in
Canada and formal approval by the shareholders of each company which is a party
to the Agreement. It is anticipated that the transaction will close during June
1999.
 
     Enertec, an Alberta corporation, provides seismic data acquisition services
in land and shallow marine environments, seismic data processing and marine
geophysical surveying and positioning services primarily in North America.
Enertec's principal executive offices are located in Calgary, Alberta.
 
     Under the terms of the Agreement, at the effective time, each Enertec
common share will be transferred to VES in exchange and as sole consideration
for 0.345 (the "Exchange Ratio") of a VES exchangeable share. At any time during
a period of ten years from the effective time, the holders of these VES
exchangeable shares will be able to exchange any or all such shares for an equal
number of shares of common stock of the Company. However, if during this ten
year period, certain minimum levels of exchangeable shares are reached within
VES, then VES is permitted to redeem any remaining VES exchangeable shares for
an equal number of shares of common stock of the Company.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                FOR THE YEARS ENDED JULY 31, 1996, 1997 AND 1998
        AND UNAUDITED FOR THE SIX MONTHS ENDED JANUARY 31, 1998 AND 1999
 
     At the effective time, pursuant to the Agreement, the Company will issue to
a trustee a share of ERS special voting stock for the benefit of the holders of
the VES exchangeable shares. The trustee will hold this voting stock pursuant to
the terms of a voting and exchange trust agreement. This agreement will entitle
the trustee, at any meeting at which stockholders of the Company are entitled to
vote, to exercise a number of votes equal to the number of VES exchangeable
shares outstanding at such time and not held by the Company or entities
controlled by the Company. These voting rights will be exercised by the trustee
only on instructions received, from time to time, from the holders of the VES
exchangeable shares not held by the Company or entities controlled by the
Company.
 
     Also at the effective time, pursuant to the Agreement, each Enertec stock
option will be exchanged for an option under the Company's stock option plan.
The number of options on common stock of the Company received on such exchange
will be equal to the number of Enertec common shares subject to the Enertec
stock option at the effective time multiplied by the Exchange Ratio, rounded
down to the nearest whole number. The exercise price per share of common stock
of the Company will be equal to the exercise price per share of the option in
respect of such Enertec common shares, immediately prior to the effective time,
divided by the Exchange Ratio. The exercise price will be decreased by the
amount attributable to any rounding down of shares. This exercise price will be
converted into U.S. dollars.
 
     The transaction is anticipated to be accounted for using the
pooling-of-interests method of accounting under United States generally accepted
accounting principles.

                                AUDITORS' REPORT
 
To the Board of Directors of
  Enertec Resource Services Inc.
 
     We have audited the consolidated balance sheets of Enertec Resource
Services Inc. as at September 30, 1998 and 1997 and the consolidated statements
of operations and retained earnings and changes in financial position for each
of the years in the three year period ended September 30, 1998. 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 in Canada. Those standards require that we plan and perform and audit
to obtain reasonable assurance whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation.
 
     In our opinion, these consolidated financial statements present fairly, in
all material aspects, the financial position of the company as at September 30,
1998 and 1997 and the results of its operations and the changes in its financial
position for each of the years in the three year period ended September 30, 1998
in accordance with generally accepted accounting principles in Canada.

1.   SIGNIFICANT ACCOUNTING POLICIES:
 
     (a) PRINCIPLES OF CONSOLIDATION:
 
     These consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiary companies. All significant inter-company
accounts and transactions have been eliminated.
 
     (b) FOREIGN CURRENCY TRANSLATION:
 
     A subsidiary, KC Offshore, L.L.C., is classified as a self-sustaining
operation such that its accounts are translated into Canadian dollars on the
following basis:
 
     (i)   assets and liabilities at the rate of exchange at the balance sheet
           date; and
 
     (ii)  revenue and expenses at the average rate of exchange for the period.
 
     Gains and losses arising from the translation of the accounts of KC
Offshore, L.L.C. are reflected in the foreign currency translation account as a
separate component of shareholders' equity.
 
     Foreign currency transactions are translated into Canadian dollars at
exchange rates prevailing at the transaction dates. The recorded amounts of
monetary assets and liabilities reflect exchange rates at the balance sheet
dates and the resultant translation gains or losses are included in operations.
 
     (c) FOREIGN CURRENCY RATE RISK:
 
     The Company is exposed to foreign currency fluctuations on its U.S. dollar
denominated cash flow. The Company considers the use of financial instruments,
including forward exchange contracts and currency options, to manage this
exposure. At January 31, 1999 there were no contracts or options outstanding.
 
     (d) REVENUE RECOGNITION:
 
     Contract revenue and related costs are recognized in the financial
statements on the basis of the extent of completion of projects as at the date
of the financial statements.
 
     (e) RESEARCH AND DEVELOPMENT:
 
     Research and development expenditures are charged to operations as
incurred.
 
     (f) CAPITAL ASSETS:
 
     Capital assets are recorded at cost. Depreciation is provided using the
straight-line method over the following periods:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     (g) MULTI-CLIENT DATA LIBRARY:
 
     The Company acquires and processes certain seismic data in respect of which
it retains ownership. This data is sold on a non-transferable and non-exclusive
basis. In most instances the Company secures purchase commitments for a portion
of the data prior to commencing the acquisition thereof. To the extent that the
costs of each project exceed the purchase commitment revenues, such costs are
capitalized. These capitalized costs are treated as follows:
 
     (i)   The total amount thereof is amortized to operations on a
           straight-line basis over a period of 36 months.
 
     (ii)  At least annually, the Company reviews the carrying value of this
           data library to assess whether there has been any permanent
           impairment of value. To the extent that the total carrying value of
           the data exceeds its estimated net realizable value, such excess is
           charged to operations.
 
     The revenue from subsequent data sales is credited to operations.
 
     (h) GOODWILL:
 
     Goodwill is being amortized on a straight-line basis over ten years. The
value of the residual unamortized balance is assessed at least annually with
reference to various factors, principally the projected future cash flows,
undiscounted, of the business to which the goodwill relates.
 
2.   BUSINESS ACQUISITIONS:
 
     Effective April 1, 1996 the Company acquired all of the shares of
PowerProbe Geophysics Inc. ("PowerProbe"), a company operating in the seismic
data acquisition business. The acquisition was accounted for as a purchase with
results of operations being consolidated from April 1, 1996.
 
     Effective June 1, 1998 the Company acquired the principal operating assets
of Extend Seismic Processing, L.L.C. ("Extend"), operating in the data
processing industry in the United States. The acquisition was accounted for as a
purchase with the results of operations being consolidated from June 1, 1998.
 
     The total purchase prices have been allocated based on estimated fair
values, as follows:

7.   SEGMENTED INFORMATION:
 
     The Company has three product lines: Data Acquisition, Marine Services and
Data Processing. The Data Acquisition product line provides seismic data
acquisition services to oil and gas companies and mineral exploration companies
in Canada and the United States. The Marine Services product line provides
geophysical and positioning services, primarily in the Gulf of Mexico. The Data
Processing product line provides seismic data conversion services to oil and gas
companies, primarily in Canada and the United States. In 1997 the Company
started a new product line which offered services to oil and gas companies with
the objective of enhancing production and reducing operating costs. Insufficient
demand for these services resulted in cessation of the business in 1998.
 
     The Company's product lines are strategic business units that each offer
different services. They are managed separately because each business applies
different technology and marketing strategies.

9.   UNCERTAINTY DUE TO THE YEAR 2000 ISSUE:
 
     The Year 2000 Issue arises because many computerized systems use two digits
rather than four to identify a year. Date-sensitive systems may recognize the
year 2000 as 1900 or some other date, resulting in errors when information using
year 2000 dates is processed. In addition, similar problems may arise in some
systems which use certain dates in 1999 to represent something other than a
date.
 
     The effects of the Year 2000 Issue may be experienced before, on, or after
January 1, 2000, and, if not addressed, the impact on operations and financial
reporting may range from minor errors to significant systems failure which could
affect an entity's ability to conduct normal business operations. It is not
possible to be certain

that all aspects of the Year 2000 Issue affecting the Company, including those
related to the efforts of customers, suppliers or other third parties, will be
fully resolved.
 
10. RELATED PARTY TRANSACTIONS:
 
     Certain premises are leased by the Company from an officer and director of
the Company. The annual lease amount is (U.S.) $45,000.
 
     At January 31, 1999, $314,413 was owed to the Company by an officer of a
wholly-owned subsidiary. This loan was advanced to the officer in connection
with his transfer to the Company's operations in Houston, Texas. The
indebtedness is due on demand, bears interest at bank prime rate minus 1.5% and
is secured by the pledging of 65,367 common shares of the Company owned by the
officer.
 
11. CANADIAN AND UNITED STATES ACCOUNTING POLICY DIFFERENCES:
 
     These financial statements have been prepared in accordance with Canadian
generally accepted accounting principles (GAAP). In certain aspects GAAP as
applied in the United States differs from Canadian GAAP.

Income Taxes
 
     For U.S. GAAP purposes, income taxes are accounted for in accordance with
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" (SFAS 109). SFAS 109 requires the asset and liability method of
accounting for income taxes. Under the asset and liability method of SFAS 109,
deferred tax assets and liabilities are recognized for the estimated future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates
in effect for the year in which those temporary differences are expected to be
recovered or settled. A valuation allowance is provided on deferred tax assets
to the extent it is not more likely than not that such deferred tax assets will
be realized. Under SFAS 109, the effect on deferred tax assets and liabilities
of a change in tax rates is recognized in income in the period that includes the
enactment date.

CONSOLIDATED STATEMENTS OF OPERATIONS
 
     For U.S. GAAP, in calculating diluted earnings per share, the diluted
weighted average number of shares outstanding is calculated using the treasury
method. Under this method, proceeds from the assumed exercise of stock options
which are in-the-money relative to the average market price for the period are
assumed to be used to purchase outstanding shares at the average market price
for the period, this purchase reduces the number of shares assumed to be issued
on the exercise of the options.
 
     The following reflects the diluted weighted average number of shares
outstanding for the reported periods:

12. SUBSEQUENT EVENT:
 
     On March 30, 1999, the Company signed a definitive combination agreement
(the "Agreement") with Veritas DGC Inc. ("Veritas DGC") and Veritas Energy
Services Inc. ("VESI"). Consummation of the Agreement is subject to a number of
conditions, including regulatory clearances in Canada and the United States,
judicial clearance in Canada and formal approval by the shareholders of each
company which is a party to the Agreement. It is anticipated that the
transaction will close during June 1999.
 
     Veritas DGC, a Delaware corporation, provides seismic data acquisition
services, data processing services and multi-client data sales to the oil and
gas industry in selected markets worldwide. Veritas DGC acquires seismic data in
land, in marine and in marsh, swamp and tidal environments and processes data
acquired by its own crews and by other operators. Veritas DGC's principal
executive offices are located in Houston, Texas.
 
     Under the terms of the Agreement, at the effective time, each Enertec
common share will be transferred to VESI in exchange and as sole consideration
for 0.345 (the "Exchange Ratio") of a VESI exchangeable share. At any time
during a period of ten years from the effective time, the holders of these VESI
exchangeable shares will be able to exchange any or all such shares for an equal
number of shares of Veritas DGC common stock. However, if during this ten year
period, certain minimum levels of exchangeable shares are reached within VESI,
then VESI is permitted to redeem any remaining VESI exchangeable shares for an
equal number of shares of Veritas DGC common stock.
 
     At the effective time, pursuant to the Agreement, the articles of Enertec
will be amended to delete the Class 1 preferred shares from the authorized
capital. Veritas DGC will issue to a trustee a special voting share for the
benefit of the holders of the VESI exchangeable shares. The trustee will hold
this voting share pursuant to the terms of a voting and exchange trust
agreement. This agreement will entitle the trustee, at any meeting at which
Veritas DGC stockholders are entitled to vote, to exercise a number of votes
equal to the number of VESI exchangeable shares outstanding at such time and not
held by Veritas DGC or entities controlled by Veritas DGC. These voting rights
will be exercised by the trustee only on instructions received, from time to
time, from the holders of the VESI exchangeable shares not held by Veritas DGC
or entities controlled by Veritas DGC.
 
     Also at the effective time, pursuant to the Agreement, each Enertec stock
option will be exchanged for an option under the Veritas DGC stock option plan.
The number of options on Veritas DGC common stock received on such exchange will
be equal to the number of Enertec common shares subject to the Enertec stock
option at the effective time multiplied by the Exchange Ratio, rounded down to
the nearest whole number. The exercise

price per share of Veritas DGC common stock will be equal to the exercise price
per share of the option in respect of such Enertec common shares, immediately
prior to the effective time, divided by the Exchange Ratio. The exercise price
will be decreased by the amount attributable to any rounding down of shares.
This exercise price will be converted into U.S. dollars.
 
     The transaction is anticipated to be accounted for using the
pooling-of-interests method of accounting under United States generally accepted
accounting principles.

<PAGE>   184
 
                             COMBINATION AGREEMENT
 
     THIS COMBINATION AGREEMENT (this "Agreement") is entered into as of March
30, 1999, by and among Veritas DGC Inc., a Delaware corporation ("Veritas"),
Veritas Energy Services Inc., an Alberta corporation ("VESI") and Enertec
Resource Services Inc., an Alberta corporation ("Enertec").
 
                                    RECITALS
 
     WHEREAS, the respective boards of directors of Veritas, VESI and Enertec
have approved the transactions contemplated by this Agreement.
 
     NOW, THEREFORE, the parties hereto hereby agree as follows:
 
                                   ARTICLE I
                                    GENERAL
 
1.1 PLAN OF ARRANGEMENT.
 
     As promptly as practicable after the execution of this Agreement, Enertec,
on a joint basis with VESI, will apply to the Court of Queen's Bench of Alberta
(the "Court") pursuant to Part 15 of the Business Corporations Act (Alberta)
(the "ABCA") for an interim order in form and substance satisfactory to Veritas
(such approval not to be unreasonably withheld or delayed) (the "Interim Order")
providing for, among other things, the calling and holding of the Enertec
Meeting (as defined below) and the VESI Meeting (as defined below) for the
purposes of considering and, if deemed advisable, approving the arrangement (the
"Arrangement") under Part 15 of the ABCA and pursuant to this Agreement and the
Plan of Arrangement substantially in the form of Exhibit A hereto (the "Plan of
Arrangement"). If the Enertec shareholders and optionholders and the VESI
exchangeable shareholders approve the Arrangement, thereafter Enertec, on a
joint basis with VESI, will take the necessary steps to submit the Arrangement
to the Court and apply for a final order of the Court approving the Arrangement
in such fashion as the Court may direct (the "Final Order"). At 12:01 a.m. (the
"Effective Time") on the date (the "Effective Date") shown on the certificate of
arrangement issued by the Registrar under the ABCA giving effect to the
Arrangement the following steps shall occur and shall be deemed to occur in the
following order without any further act or formality:
 
     (a)   The articles of Enertec shall be amended to delete the Class 1
Preferred Shares from the authorized share capital;
 
     (b)   The articles of VESI shall be amended to:
 
        (i)   delete Section 4.1(c) of the provisions attaching to the existing
              exchangeable shares of VESI (the "Exchangeable Shares") and to
              substitute therefor the following:
 
             "(c)  except as provided for in the rights, privileges,
                   restrictions and conditions attaching to the Class A
                   Exchangeable Shares, or any series thereof, redeem or
                   purchase any other shares of the Corporation ranking equally
                   with the Exchangeable Shares with respect to the payment of
                   dividends or on any liquidation distribution;"
 
        (ii)   delete Section 4.1(d) of the provisions attaching to the
               Exchangeable Shares and to substitute therefor the following:
 
             "(d)  issue any Exchangeable Shares other than by way of stock
                   dividends to the holders of such Exchangeable Shares or as
                   contemplated by the Support Agreement; or";
 
        (iii)  delete Section 4.1(e) of the provisions attaching to the
               Exchangeable Shares and to substitute therefor the following:
 
             "(e)  except for the designation of one or more further series of
                   Class A Exchangeable Shares, amend the articles or by-laws of
                   the Corporation.";
 
                                       B-1
<PAGE>   185
 
        (iv)  delete the third sentence of Section 6.6 of the provisions
              attaching to the Exchangeable Shares and to substitute therefor
              the following:
 
                "In any case in which the redemption by the Corporation of
                Retracted Shares, or the redemption by the Corporation of any
                Class A Exchangeable Shares, would be contrary to liquidity or
                solvency requirements or other provisions of applicable law, the
                Corporation shall redeem Retracted Shares and Class A
                Exchangeable Shares on a PRO RATA basis and shall issue to each
                holder of Retracted Shares a new certificate, at the expense of
                the Corporation, representing the Retracted Shares not redeemed
                by the Corporation.";
 
        (v)   delete the restriction set out in Section 2.1(f) of that Plan of
              Arrangement attached to that Certificate of Amendment of VESI
              dated August 30, 1996;
 
        (vi)  increase the number of authorized common shares in the capital of
              VESI to an unlimited number of common shares;
 
        (vii) authorize a further class of exchangeable shares, ranking pari
              passu with the Exchangeable Shares, unlimited in number, issuable
              in series and having the terms and conditions set forth in the
              Plan of Arrangement (the "Class A Exchangeable Shares");
 
        (viii) designate the first series of Class A Exchangeable Shares as
               "Class A Exchangeable Shares Series 1" limited in number to
               25,000,000 shares and having the terms and conditions set forth
               in the Plan of Arrangement (the "Series 1 Exchangeable Shares");
               and
 
        (ix)  add the following provision to part 7 of such articles:
 
            "Meetings of shareholders of the Corporation shall be held in the
            location determined by the directors of the Corporation, and may be
            held in Houston, Texas, or at any location within Alberta.";
 
     (c)   That Support Agreement dated August 30, 1996 between Veritas and VESI
shall be amended to delete Section 2(i) thereof and to substitute therefor the
following:
 
        "(i)  OWNERSHIP OF OUTSTANDING SHARES. Without the prior approval of
              Veritas and the prior approval of the holders of the Exchangeable
              Shares given in accordance with Section 9.2 of the Exchangeable
              Share Provisions, Digicon covenants and agrees in favour of
              Veritas that, as long as any outstanding Exchangeable Shares are
              owned by any person or entity other than Digicon or any of its
              Subsidiaries, Digicon will be and remain the direct or indirect
              beneficial owner of all issued and outstanding shares in the
              capital of Veritas and all outstanding securities of Veritas
              carrying or otherwise entitled to voting rights in any
              circumstances, in each case other than the Exchangeable Shares and
              other than the Class A Exchangeable Shares of Veritas.";
 
     (d)   Subject to the approval of CIBC Mellon Trust Company (the
"Depositary"), that Voting and Exchange Trust Agreement dated August 30, 1996
between Veritas, VESI and the Depositary (as successor to The R-M Trust Company)
shall be amended to delete the definition of "Insolvency Event" and to
substitute the following:
 
       "'Insolvency Event' means the institution by Veritas of any proceeding to
       be adjudicated a bankrupt or insolvent or to be dissolved or wound-up, or
       the consent of Veritas to the institution of bankruptcy, insolvency,
       dissolution or winding-up proceedings against it, or the filing of a
       petition, answer or consent seeking dissolution or winding-up under any
       bankruptcy, insolvency or analogous laws, including without limitation
       the Companies' Creditors Arrangement Act (Canada) and the Bankruptcy and
       Insolvency Act (Canada), and the failure by Veritas to contest in good
       faith any such proceedings commenced in respect of Veritas within 15 days
       of becoming aware thereof, or the consent by Veritas to the filing of any
       such petition or to the appointment of a receiver, or the making by
       Veritas of a general assignment for the benefit of creditors, or the
       admission in writing by Veritas of its inability to pay its debts
       generally as they become due, or Veritas not being permitted, pursuant to
       liquidity or solvency requirements of applicable law, to redeem any
       Exchangeable Shares in accordance with the
 
                                       B-2
<PAGE>   186
 
terms thereof or to redeem any shares of any series of Class A Exchangeable
Shares of the Corporation in accordance with the terms thereof.";
 
     (e)   Each of the common shares of Enertec (the "Enertec Common Shares")
(other than Enertec Common Shares held by holders who have exercised their
rights of dissent in accordance with the Plan of Arrangement and who are
ultimately entitled to be paid the fair value for such shares) will be
transferred to VESI in consideration for a number of Series 1 Exchangeable
Shares at an exchange ratio equal to 0.345 of a Series 1 Exchangeable Share for
each Enertec Common Share (the "Exchange Ratio"), and each such holder of
Enertec Common Shares will receive that whole number of Series 1 Exchangeable
Shares resulting from the transfer of such holder's Enertec Common Shares. In
lieu of fractional Series 1 Exchangeable Shares, each holder of an Enertec
Common Share who otherwise would be entitled to receive a fraction of a Series 1
Exchangeable Share shall be paid by VESI an amount determined in accordance with
the Plan of Arrangement;
 
     (f)   Upon the transfer of shares referred to in Section 1.1(e) above:
 
        (i)    each holder of an Enertec Common Share shall cease to be such a
               holder, shall have his name removed from the register of holders
               of Enertec Common Shares and shall become a holder of the number
               of fully paid Series 1 Exchangeable Shares to which he is
               entitled as a result of the transfer referred to in Section
               1.1(e) above and such holder's name shall be added to the
               register of holders of Series 1 Exchangeable Shares accordingly;
 
        (ii)   VESI shall become the legal and beneficial owner of all of the
               Enertec Common Shares so transferred; and
 
        (iii)  the Shareholders Rights Plan Agreement between Enertec and
               Montreal Trust Company of Canada made as of December 11, 1997, as
               amended and restated as of March 6, 1998 (the "Enertec Rights
               Agreement"), and all outstanding Rights (as defined in such
               agreement) will be terminated, void and of no further force or
               effect;
 
     (g)   Holders of Enertec Common Shares shall be entitled to make an income
tax election pursuant to section 85 of the Income Tax Act (Canada) (the "ITA")
with respect to the transfer of their Enertec Common Shares to VESI referred to
in Section 1.1(e) by providing two signed copies of the necessary election forms
to VESI within 90 days following the Effective Date, duly completed with the
details of the number of shares transferred and the applicable agreed amounts
for the purposes of such elections. Thereafter, subject to the election forms
complying with the provisions of the ITA, the forms will be signed by VESI and
returned to such holders of Enertec Common Shares within 180 days following the
Effective Date for filing with Revenue Canada;
 
     (h)   Veritas shall issue to and deposit with the Depositary the Voting
Share (as defined in the Voting and Exchange Trust Agreement (as defined
herein)), in consideration of the payment to Veritas of US $1, to be thereafter
held by the Depositary as trustee for and on behalf of, and for the use and
benefit of, the holders of the Series 1 Exchangeable Shares, in accordance with
the Voting and Exchange Trust Agreement; and
 
     (i)   Each of the then outstanding options to purchase Enertec Common
Shares (collectively, the "Enertec Options") (which includes all outstanding
options granted under Enertec's stock option plan (the "Enertec Option Plan")
will and without any further action on the part of any holder thereof (herein,
an "optionholder"), be exchanged for an option (collectively, the "Veritas
Options") under the Third Amended and Restated 1992 Employee Nonqualified Stock
Option Plan (the "Veritas Option Plan") to purchase that number of shares of the
common stock, $.01 par value per share, of Veritas (the "Veritas Common Stock")
determined by multiplying the number of Enertec Common Shares subject to such
Enertec Option at the Effective Time by the Exchange Ratio, at an exercise price
per share of Veritas Common Stock equal to the exercise price per share of such
Enertec Option immediately prior to the Effective Time, divided by the Exchange
Ratio. Such option price shall be converted into a United States dollar
equivalent based on the rate of exchange applicable at the Effective Time as
stated in that edition of The Wall Street Journal next published after the
Effective Time. If the foregoing calculation results in an exchanged Enertec
Option being exercisable for a fraction of a share of Veritas Common Stock, then
the number of shares of Veritas Common Stock subject to such option will be
rounded down to the nearest whole number of shares, and the total exercise price
for the Veritas Option will be reduced by the exercise price of the fractional
share. Each Veritas Option shall be:

<PAGE>   187
 
        (i)    fully vested immediately after the Effective Time; and
 
        (ii)   for a term commencing at the Effective Time and ending as
               follows:
 
                 (A)  for each optionholder who:
 
                 (1)   is an Enertec director, officer or employee as at the
                       Effective Time (a "Current optionholder"); and
 
                 (2)   after the Effective Time is employed or retained by
                       Veritas, Enertec or one of their Subsidiaries,
 
                 on the date as set forth in subsections 5(b) and (d) of the
                 Enertec Option Plan;
 
             (B)  for each Current optionholder who at the Effective Time is not
                  retained as a director, officer or employee of Veritas,
                  Enertec or one of their Subsidiaries, on the date that is the
                  first business day on or immediately after the date that is 90
                  days after the later of the Effective Date and the date such
                  director, officer or employee is terminated; or
 
             (C)  notwithstanding the provisions of (A) and (B) above, the
                  Enertec Option Plan or the Veritas Option Plan, for each
                  Current optionholder with an executive termination contract of
                  the type set out and disclosed in paragraph 5(e)(i) of the
                  Enertec Disclosure Letter (as defined below) (an "Executive
                  Termination Contract"), on the current expiry date of such
                  option (the sixth anniversary date).
 
    The term, exerciseability, and all other terms and conditions of the Enertec
    Options exchanged in accordance with this Section 1.1(i) will otherwise be
    unchanged by the provisions of this Section 1.1(i) and shall operate in
    accordance with their terms and the Veritas Option Plan shall be amended
    accordingly as required.
 
1.2 ALLOCATION OF CONSIDERATION.
 
     It is acknowledged and agreed that:
 
     (a)   the sole consideration to be received by the holders of Enertec
Common Shares for the transfer of such shares to VESI contemplated in Section
1.1(e) shall be the Series 1 Exchangeable Shares issued in connection with such
transfer as contemplated in Section 1.1(e); and
 
     (b)   all other rights and benefits received by the holders of Enertec
Common Shares in connection with the consummation of the Arrangement shall be in
consideration of the grant by such holders to Veritas of Veritas' rights in
respect of the Series 1 Exchangeable Shares and the other consideration received
by Veritas from the holders of Enertec Common Shares (excluding the Enertec
Common Shares) including, without limitation, the termination of the Rights (as
defined in the Enertec Rights Agreement).
 
1.3 ADJUSTMENTS FOR CAPITAL CHANGES.
 
     If, prior to the Effective Time, Veritas or Enertec recapitalizes through a
subdivision of its outstanding shares into a greater number of shares, or a
combination of its outstanding shares into a lesser number of shares, or
reorganizes, reclassifies or otherwise changes its outstanding shares into the
same or a different number of shares of other classes, or declares a dividend on
its outstanding shares payable in shares of its capital stock or securities
convertible or exchangeable into shares of its capital stock, then the Exchange
Ratio will be adjusted appropriately so as to maintain the relative
proportionate interests of the holders of Enertec Common Shares and the holders
of the shares of Veritas Common Stock. No such changes shall be made by either
Veritas or Enertec other than those made in accordance with this Agreement.
 
1.4 DISSENTING SHARES.
 
     Holders of Enertec Common Shares may exercise rights of dissent with
respect to such shares in connection with the Arrangement pursuant to and in the
manner set forth in Section 184 of the ABCA and Section 3.1 of the Plan of
Arrangement (such holders referred to as "Dissenters" or as "Dissenting
Shareholders"). Enertec shall
                                       B-4
<PAGE>   188
 
give Veritas (i) prompt notice of any written demands of a right of dissent,
withdrawals of such demands, and any other instruments served pursuant to the
ABCA and received by Enertec and (ii) the opportunity to participate in all
negotiations and proceedings with respect to such rights. Without the prior
written consent of Veritas, acting reasonably, except as required by applicable
law, Enertec shall not make any payment with respect to any such rights or offer
to settle or settle any such rights. All payments to Dissenters shall be the
sole responsibility of Enertec, and Veritas will not directly or indirectly
provide any funds for the purposes of making payments to Dissenters. In the
event that Enertec does not have sufficient funds to make payments to
Dissenters, Enertec will undertake to borrow the funds necessary to make such
payments from sources other than Veritas or any Veritas Subsidiary (as defined
below). Holders of Exchangeable Shares may exercise rights of dissent with
respect to such shares in connection with the Arrangement pursuant to and in the
manner set forth in Section 184 of the ABCA and Section 3.1 of the Plan of
Arrangement. All payments to dissenting shareholders of VESI shall be the sole
responsibility of Veritas, and Enertec will not directly or indirectly provide
any funds for the purposes of making payments to such dissenters. In the event
that Veritas does not have sufficient funds to make payments to such dissenters,
Veritas will undertake to borrow the funds necessary to make such payments from
sources other than Enertec or any Enertec Subsidiary (as defined below).
 
1.5 OTHER EFFECTS OF THE ARRANGEMENT.
 
     At the Effective Time: (a) the bylaws of Enertec immediately prior to the
Effective Time will continue as the bylaws of Enertec, subject to later
amendment; (b) the directors of Enertec will be those appointed by VESI; (c) the
officers of Enertec will be as designated by the board of directors of Enertec
prior to the Effective Time, subject to later removal and appointment of other
officers; (d) each Enertec Common Share and each Enertec Option outstanding
immediately prior to the Effective Time will be transferred or exchanged, as
applicable, as provided in Section 1.1; and (e) the Arrangement will, from and
after the Effective Time, have all of the effects provided by applicable law,
including, without limitation, the ABCA.
 
1.6 AMENDED VERITAS CHARTER.
 
     Prior to the Closing, Veritas shall have amended its certificate of
incorporation to read as set forth in Exhibit B hereto (the "Restated Veritas
Charter").
 
1.7 JOINT PROXY STATEMENT; S-3 REGISTRATION STATEMENT.
 
     (a)   As promptly as practicable after execution of this Agreement, Veritas
and Enertec, jointly with VESI, shall prepare and file with the Securities and
Exchange Commission (the "SEC") a preliminary joint management information
circular and proxy statement (the "Joint Proxy Statement"), together with any
other documents required by the Securities Act of 1933, as amended (the
"Securities Act"), or the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), in connection with the Arrangement and the other transactions
contemplated hereby. The Joint Proxy Statement shall constitute (i) the
management information circular of Enertec with respect to the meeting of
shareholders and optionholders of Enertec with respect to the Arrangement and
the approval of certain matters in connection therewith (the "Enertec Meeting"),
(ii) the management information circular of VESI with respect to the meeting of
exchangeable shareholders of VESI with respect to the Arrangement and the
approval of certain matters in connection therewith (the "VESI Meeting"), and
(iii) the proxy statement of Veritas with respect to the meeting of stockholders
of Veritas with respect to the approval of the Restated Veritas Charter (the
"Veritas Stockholders Meeting"). As promptly as practicable after the
preliminary Joint Proxy Statement is cleared by the SEC, Veritas, VESI and
Enertec shall cause the Joint Proxy Statement to be mailed to the applicable
stockholders of Veritas, the shareholders and optionholders of Enertec and the
exchangeable shareholders of VESI. Veritas and Enertec, jointly with VESI, shall
prepare and file with the SEC a request for no action seeking to confirm the
availability of an exemption pursuant to Section 3(a)(10) of the Securities Act
with respect to the issuance of the Series 1 Exchangeable Shares pursuant to the
Arrangement, and if such exemption is not available, Veritas and VESI will file
a registration statement on Form F-4 or other applicable form (the "Form F-4")
with the SEC and use their best efforts to cause it to be declared effective. If
Veritas determines on the advice of its outside counsel (with the concurrence of
outside counsel for Enertec) that it is necessary to file a registration
statement on Form S-3 (the "Form S-3") in order to
 
                                       B-5
<PAGE>   189
 
register the Veritas Common Stock to be issued from time to time after the
Effective Time upon exchange of the Series 1 Exchangeable Shares, then Veritas
shall file the Form S-3 with the SEC and use its best efforts to maintain the
effectiveness of such registration for the period that such Series 1
Exchangeable Shares remain outstanding, and Veritas shall use its best efforts
(with the reasonable cooperation of Enertec, if required) to cause the Form S-3
to become effective. Notwithstanding anything herein to the contrary, Veritas
shall be under no obligation to file the Form S-3 if it shall have determined on
the advice of its outside counsel (with the concurrence of outside counsel for
Enertec) that the issuance of shares of Veritas Common Stock upon exchange of
the Series 1 Exchangeable Shares after the Effective Time is exempt from the
registration requirements of Section 5 of the Securities Act by virtue of
Section 3(a)(9) and/or 3(a)(10) thereof. In connection with such determination,
Veritas, VESI and Enertec shall prepare and file with the SEC a request for no
action seeking to confirm the availability of such an exemption.
 
     (b)   Each party shall promptly furnish to the other parties all
information concerning such party and its stockholders as may be reasonably
required in connection with any action contemplated by this Section 1.7. The
Joint Proxy Statement and, if required, the Form S-3, shall comply in all
material respects with all applicable requirements of law. Each of Veritas, VESI
and Enertec will notify the others promptly of the receipt of any comments from
the SEC and of any request by the SEC for amendments or supplements to the Joint
Proxy Statement or the Form F-4 and Form S-3, if required, or for additional
information, and will supply the other with copies of all correspondence with
the SEC with respect to the Joint Proxy Statement or the Form F-4 and Form S-3,
if required. Whenever any event occurs which should be set forth in an amendment
or supplement to the Joint Proxy Statement or the Form S-3, if required,
Veritas, VESI or Enertec, as the case may be, shall promptly inform the others
of such occurrence and cooperate in filing with the SEC, and/or mailing to
stockholders of Veritas, Enertec and VESI as may be applicable, such amendment
or supplement.
 
     (c)   Veritas, VESI and Enertec shall take any action required to be taken
under any applicable provincial or state securities laws (including "blue sky"
laws) in connection with the issuance of the Veritas Common Stock and the
Arrangement; provided, however, that with respect to the blue sky and Canadian
provincial qualifications, neither Veritas, Enertec nor VESI shall be required
to register or qualify as a foreign corporation or reporting issuer (other than
Alberta and Ontario, Canada, in the case of Enertec and VESI, and Delaware in
the case of Veritas) where any such entity is not now so registered or qualified
except as to matters and transactions arising solely from the offer and sale of
the Veritas Common Stock or the issuance of the Series 1 Exchangeable Shares.
 
1.8 MATERIAL ADVERSE EFFECT.
 
     In this Agreement, any reference to any event, change or effect being
"material" with respect to any entity or group of entities means any material
event, change or effect related to the condition (financial or otherwise),
properties or business of such entity or group of entities. In this Agreement,
the term "Material Adverse Effect" used with respect to any party means any
event, change or effect that is materially adverse to the condition (financial
or otherwise), properties or business of such party and its subsidiaries, taken
as a whole; provided that, a Material Adverse Effect shall not include any
adverse effect resulting from changes in general economic conditions or
conditions generally affecting the industries in which Veritas, VESI or Enertec
operate, including without limitation, fluctuations in the prices of petroleum,
natural gas and related hydrocarbons and fluctuations in the demand for the
parties' products and services that result from fluctuations in such prices.

     Unless otherwise specified, all references in this Agreement to "dollars"
or "$" shall mean United States dollars.

interests" for accounting purposes.

                                   ARTICLE II
                   REPRESENTATIONS AND WARRANTIES OF ENERTEC
 
     Except as set forth in a letter dated the date of this Agreement and
delivered by Enertec to Veritas concurrently herewith (the "Enertec Disclosure
Letter"), Enertec hereby represents and warrants to Veritas and VESI that:
 
2.1 ORGANIZATION AND STANDING.
 
     Enertec and each partnership, joint venture, corporation, association or
other business entity of which more than 50% of the total voting power of shares
of stock or units of ownership or beneficial interest entitled to vote in the
election of directors (or members of a comparable governing body) is owned or
controlled, directly or indirectly, by Enertec (the "Enertec Subsidiaries"), is
an entity duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation or organization, has full requisite
power and authority to carry on its business as it is currently conducted, and
to own, lease and operate the properties currently owned, leased and operated by
it, and is duly qualified or licensed to do business and is in good standing as
a foreign corporation or organization authorized to do business in all
jurisdictions in which the character of the properties owned or leased or the
nature of the business conducted by it would make such qualification or
licensing necessary, except where the failure to be so qualified or licensed
would not have a Material Adverse Effect on Enertec. The Enertec Disclosure
Letter sets forth a complete list of the Enertec Subsidiaries, the percentage of
each subsidiary's outstanding capital stock or other ownership interest owned by
Enertec or another Enertec Subsidiary (and a description of any lien, charge,
mortgage, security interest, option, preferential purchase right or other right
or interest of any other person (collectively, an "Encumbrance") on such stock
or other ownership interest) and a complete list of each jurisdiction in which
each of Enertec and each Enertec Subsidiary is duly qualified and in good
standing to do business. Enertec is a taxable Canadian corporation (within the
meaning of the ITA).
 
2.2 AGREEMENT AUTHORIZED AND ITS EFFECT ON OTHER OBLIGATIONS.
 
     (a)   Enertec has all requisite corporate power and authority to enter into
this Agreement and, subject to approval of this Agreement and the Arrangement by
the shareholders and optionholders of Enertec and approval by the Court, to
perform its obligations hereunder and to consummate the Arrangement and the
other transactions contemplated by this Agreement. The execution and delivery of
this Agreement by Enertec and, subject to approval of this Agreement and the
Arrangement by the shareholders and optionholders of Enertec and approval by the
Court, the consummation by Enertec of the Arrangement and the other transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of Enertec. This Agreement has been duly executed and delivered by
Enertec and is the valid and binding obligation of Enertec, enforceable in
accordance with its terms, except that such enforceability may be subject to (i)
bankruptcy, insolvency, reorganization or other similar laws affecting or
relating to enforcement of creditors' rights generally and (ii) general
equitable principles.
 
     (b)   Neither the execution, delivery and performance of this Agreement or
the Arrangement by Enertec, nor the consummation of the transactions
contemplated hereby or thereby by Enertec nor compliance with the provisions
hereof or thereof by Enertec will: (i) conflict with, or result in any
violations of, the articles or bylaws of Enertec or any equivalent document of
any of the Enertec Subsidiaries, as amended, or (ii) result in any breach of or
cause a default (with or without notice or lapse of time, or both) under, or
give rise to a right of termination, amendment, cancellation or acceleration of
any obligation contained in, or the loss of any material benefit under, or
result in the creation of any Encumbrance upon any of the material properties or
assets of Enertec or any of the Enertec Subsidiaries under any term, condition
or provision of any loan or credit agreement, note, bond, mortgage, indenture,
lease or other material agreement, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to Enertec or any of the Enertec
Subsidiaries or their respective properties or assets, other than any such
breaches, defaults, losses, or encumbrances which, individually or in the
aggregate, would not have a Material Adverse Effect on Enertec.

other governmental authority or instrumentality, domestic or foreign (each a
"Governmental Entity"), is required to be obtained by Enertec or any of the
Enertec Subsidiaries in connection with the execution and delivery of this
Agreement or the Plan of Arrangement or the consummation of the transactions
contemplated hereby or thereby, except for: (i) the filing with the applicable
Canadian provincial securities commissions or regulatory authorities (the
"Commissions") and the Court and the mailing to shareholders and optionholders
of Enertec of the Joint Proxy Statement relating to the Enertec Meeting to be
held with respect to the approval of this Agreement and the Arrangement, (ii)
the furnishing to the SEC of such reports and information under the Exchange Act
and the rules and regulations promulgated by the SEC thereunder, as may be

hereby (the "SEC Filings"); (iii) approval by the Court of the Arrangement and
the filings of the articles of arrangement and other required arrangement or
other documents as required by the ABCA; (iv) such filings, authorizations,

"anti-takeover" or other similar statutes, any other applicable federal,
provincial or state securities laws and the rules of The New York Stock Exchange
("NYSE") or The Toronto Stock Exchange ("TSE"); (v) such filings and
notifications as may be necessary under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"); (vi) such notices and
filings as may be necessary under the Investment Canada Act and under the
Competition Act (Canada); and (vii) where the failure to obtain such consents,
approvals, etc., would not prevent or delay the consummation of the Arrangement
or otherwise prevent Enertec from performing its obligations under this
Agreement and would not reasonably be expected to have a Material Adverse Effect
on Enertec.
 
2.4 CAPITALIZATION.
 
     The authorized capital stock of Enertec consists of an unlimited number of
Enertec Common Shares and an unlimited number of Class 1 Preferred Shares. At
the close of business on March 22, 1999, 6,931,668 Enertec Common Shares were
issued and outstanding, no Class 1 Preferred Shares were issued and outstanding
and no Enertec Common Shares were held by Enertec in its treasury. As of March
22, 1999, (i) an aggregate of 827,719 Enertec Common Shares were reserved for
issuance pursuant to outstanding Enertec Options granted under the Enertec
Option Plan and (ii) a number of Enertec Common Shares equal to the aggregate of
the number of issued and outstanding Enertec Common Shares and the number of
Enertec Common Shares reserved for issuance pursuant to the Enertec Options were
reserved for issuance pursuant to the Enertec Rights Agreement. All issued and
outstanding Enertec Common Shares have been duly authorized, validly issued and
are fully paid and non-assessable. The Enertec Common Shares are now (and will
immediately prior to the Effective Time be) listed and posted for trading on the
TSE.
 
2.5 SECURITIES REPORTS AND FINANCIAL STATEMENTS.
 
     Enertec has filed all forms, reports and documents required to be filed by
it by the Commissions, the TSE, or pursuant to relevant Canadian securities
statutes, regulations, policies and rules (collectively, the "Enertec Securities
Reports"), all of which have complied at their respective dates of filing in all
material respects with all applicable requirements of such statutes,
regulations, policies and rules. None of the Enertec Securities Reports, at the
time filed or as subsequently amended, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading. The financial
statements of Enertec contained in the Enertec Securities Reports complied in
all material respects with the then applicable accounting requirements and the
published rules and regulations of the relevant Canadian securities statutes
with respect thereto, were prepared in accordance with Canadian generally
accepted accounting principles applied on a consistent basis during the periods
involved (except as may have been indicated in the notes thereto or, in the case
of unaudited statements, as permitted by applicable laws, rules or regulations)
and fairly present (subject, in the case of the unaudited statements, to normal,
year-end audit adjustments) the consolidated financial position of Enertec and
its consolidated Enertec Subsidiaries as at the respective dates thereof and the
consolidated results of their operations and cash flows for the respective
periods then ended. There has been no change in Enertec's
 
                                       B-8
<PAGE>   192
 
accounting policies or the methods of making accounting estimates or changes in
estimates that are material to such financial statements, except as described in
the notes thereto.
 
2.6 LIABILITIES.
 
     Enertec and the Enertec Subsidiaries do not have any material liabilities
or obligations, either accrued, absolute, contingent, or otherwise, or have any
knowledge of any potential liabilities or obligations, other than those (i)
disclosed in the Enertec Securities Reports, (ii) set forth in the Enertec
Disclosure Letter or (iii) incurred in the ordinary course of business since
December 31, 1998.
 
2.7 INFORMATION SUPPLIED.
 
     None of the information supplied or to be supplied by Enertec for inclusion
or incorporation by reference in the Joint Proxy Statement (and, if filed, the
Form S-3) will, at the time the Joint Proxy Statement is mailed to the
shareholders of Enertec and at the time of the Enertec Meeting (and, if filed,
at the time the Form S-3 is declared effective), contain any untrue statement of
a material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they are made, not misleading. The Joint Proxy Statement will comply as to
form in all material respects with the provisions of the ABCA and applicable
Canadian securities laws and the rules and regulations of the Commissions and
the TSE.
 
2.8 NO DEFAULTS.
 
     Neither Enertec nor any Enertec Subsidiary is, or has received notice that
it would be with the passage of time, in default or violation of any term,
condition or provision of (i) its charter documents or bylaws; (ii) any
judgment, decree or order applicable to it; or (iii) any loan or credit
agreement, note, bond, mortgage, indenture, material contract, agreement, lease,
license or other instrument to which Enertec or any Enertec Subsidiary is now a
party or by which it or any of its properties or assets may be bound, except in
the case of item (iii) for defaults and violations which, individually or in the
aggregate, would not have a Material Adverse Effect on Enertec.
 
2.9 LITIGATION; INVESTIGATIONS.
 
     There is no claim, action, suit or proceeding pending or, to the knowledge
of Enertec, threatened, which would, if adversely determined, individually or in
the aggregate, have a Material Adverse Effect on Enertec, nor is there any
judgment, decree, injunction, rule or order of any Governmental Entity or
arbitrator outstanding against Enertec or any of the Enertec Subsidiaries
having, or which, insofar as reasonably can be foreseen, in the future could
have, any such effect. There is no investigation pending or, to the knowledge of
Enertec, threatened, against Enertec or any of the Enertec Subsidiaries before
any Governmental Entity.

Enertec or the Enertec Subsidiaries free and clear of any Encumbrance other than
such Encumbrances as are listed in the Enertec Disclosure Letter. Except as
otherwise indicated in such letter or in the ordinary course of business,
neither Enertec nor the Enertec Subsidiaries has granted to any other person any
license to use any Enertec Intellectual Property. Neither Enertec nor the
Enertec Subsidiaries has received any notice of infringement, misappropriation,
or conflict with, the intellectual property rights of others in connection with
the use by Enertec or the Enertec Subsidiaries of the Enertec Intellectual
Property.
 
2.15 TITLE TO PROPERTIES.
 
     Except for goods and other property sold, used or otherwise disposed of in
the ordinary course of business for fair value, Enertec has good and
indefeasible title to all its properties, interests in properties and assets,
real and personal, reflected in its December 31, 1998 financial statements, free
and clear of any Encumbrance, except (i) Encumbrances reflected in the balance
sheet of Enertec dated December 31, 1998, (ii) liens for current taxes not yet
due and payable, and (iii) such imperfections of title, easements and
Encumbrances, if any, as are not substantial in character, amount, or extent and
do not and will not materially detract from the value, or interfere with the
present use, of the property subject thereto or affected thereby, or otherwise
materially impair business operations. All leases pursuant to which Enertec or
any Enertec Subsidiary leases (whether as lessee or lessor) any substantial
amount of real or personal property are in good standing, valid, and effective;
and there is not, under any such leases, any existing or prospective default or
event of default or event which with notice or lapse of time, or both, would
constitute a default by Enertec or any Enertec Subsidiary and in respect to
which Enertec or a Enertec Subsidiary has not taken adequate steps to prevent a
default from occurring. The buildings and premises of Enertec and the Enertec
Subsidiaries that are necessary for the operation of its business are in good
operating condition and repair, subject only to ordinary wear and tear. All
major items of operating equipment of Enertec and the Enertec Subsidiaries
necessary for the operation of their businesses are in good operating condition
and in a state of reasonable maintenance and repair, ordinary wear and tear
excepted, and are free from any known defects except as may be repaired by
routine maintenance and such minor defects as to not substantially interfere
with the continued use thereof in the conduct of normal operations.
 
2.16 ENVIRONMENTAL MATTERS.
 
     (a)   Environmental Conditions.  There are no environmental conditions or
circumstances, such as the presence or release of any hazardous substance, on
any property presently or previously owned or leased by Enertec or the Enertec
Subsidiaries that could result in a Material Adverse Effect on Enertec;
                                      B-11
<PAGE>   195
 
     (b)   Permits, etc.  Enertec and the Enertec Subsidiaries have in full
force and effect all material environmental permits, licenses, approvals and
other authorizations required to conduct their operations and are operating in
material compliance thereunder;
 
     (c)   Compliance.  Enertec's and the Enertec Subsidiaries' operations and
use of their assets do not violate any applicable United States or Canadian or
other federal, provincial, state or local law, statute, ordinance, rule,
regulation, order or notice requirement pertaining to (i) the condition or
protection of air, groundwater, surface water, soil, or other environmental
media, (ii) the environment, including natural resources or any activity which
affects the environment, or (iii) the regulation of any pollutants,
contaminants, waste, substances (whether or not hazardous or toxic), including,
without limitation, the Comprehensive Environmental Response Compensation and
Liability Act (42 USC. sec. 9601 et seq.), the Hazardous Materials
Transportation Act (49 USC. sec. 1801 et seq.), the Resource Conservation and
Recovery Act (42 USC. sec. 1609 et seq.) the Clean Water Act (33 USC. 1251 et
seq.), the Clean Air Act (42 USC. sec. 7401 et seq.), the Toxic Substances
Control Act (17 USC. sec. 2601 et seq.), the Safe Drinking Water Act (42 USC.
sec. 201 and sec. 300f et seq.), the Rivers and Harbors Act (33 USC. sec. 401 et
seq.), the Oil Pollution Act (33 USC. sec. 2701 et seq.) and analogous,
Canadian, foreign, provincial, state and local provisions, as any of the
foregoing may have been amended or supplemented from time to time (collectively
the "Applicable Environmental Laws"), except for violations which, either singly
or in the aggregate, would not result in a Material Adverse Effect on Enertec;
 
     (d)   Past Compliance.  None of the operations or assets of Enertec or the
Enertec Subsidiaries has ever been conducted or used by Enertec or the Enertec
Subsidiaries in such a manner as to constitute a violation of any of the
Applicable Environmental Laws, except for violations which, either singly or in
the aggregate, would not result in a Material Adverse Effect on Enertec;
 
     (e)   Environmental Claims.  No notice has been served on Enertec or any
Enertec Subsidiaries from any entity, Governmental Entity or individual
regarding any existing, pending or threatened investigation or inquiry related
to alleged violations under any Applicable Environmental Laws, or regarding any
claims for remedial obligations or contribution under any Applicable
Environmental Laws, other than any of the foregoing which, either singly or in
the aggregate, would not result in a Material Adverse Effect on Enertec; and
 
     (f)   Renewals.  Enertec does not know of any reason why it or Veritas
would not be able to renew any of the permits, licenses, or other authorizations
required pursuant to any Applicable Environmental Laws to operate and use any of
Enertec's or the Enertec Subsidiaries' assets for their current purposes and
uses.
 
2.17 COMPLIANCE WITH OTHER LAWS.
 
     Neither Enertec nor any Enertec Subsidiary is in violation of or in default
with respect to, or in alleged violation of or alleged default with respect to
any other applicable law or any applicable rule, regulation, or any writ or
decree of any court or any Governmental Entity, or delinquent with respect to
any report required to be filed with any Governmental Entity, except for
violations which, either singly or in the aggregate, do not and are not expected
to result in a Material Adverse Effect on Enertec.
 
2.18 TAXES.
 
     Except with respect to failures which, in the aggregate, would not result
in a Material Adverse Effect on Enertec: (a) proper, complete and accurate
federal, provincial, state, local and foreign returns of income (including net
income, gross income, income as specially defined, earnings, profits or selected
items of income, earnings or profits), capital, withholding, environmental,
commodity, ad valorem, value added, sales, use, license, goods and services,
franchise, gross revenue or gross receipt, gains, turnover, transfer, excise,
payroll, unemployment, disability, social security (or similar), property,
occupation, employment, stamp, customs duties, workers' compensation,
unemployment insurance or compensation, premium, windfall profits taxes,
alternative or add-on minimum taxes, fees, imposts, assessments or charges of
any kind whatsoever, together with any interest and any penalties or additional
amounts imposed by any taxing authority (collectively, the "Tax" or "Taxes"),
and any and all other tax returns, declarations, reports, information returns,
statements and estimates have been filed with appropriate Governmental Entities,
domestic and foreign, by Enertec and each of the Enertec Subsidiaries, as
applicable, for each period for which any returns, declarations, reports,
information returns,
                                      B-12
<PAGE>   196
 
statements or estimates were due (taking into account any extensions of time to
file before the date hereof); (b) all Taxes shown by such returns, declarations,
reports, information returns, or statements to be payable and any other Taxes
due and payable have been paid other than those being contested in good faith by
Enertec or an Enertec Subsidiary and indicated in the Enertec Disclosure Letter;
and (c) the tax provision reflected in Enertec's financial statements is
adequate, in accordance with Canadian or United States (as the case may be)
generally accepted accounting principles, to cover liabilities of Enertec and
the Enertec Subsidiaries for all unpaid Taxes applicable to Enertec and the
Enertec Subsidiaries or their assets or businesses. Other than as reflected in
Enertec's financial statements, Enertec and the Enertec Subsidiaries have not
received any written notice of reassessment or any other notification of
imposition of Taxes from any Governmental Entity and no material Tax liability
has been assessed, proposed to be assessed, incurred or accrued, and no
deficiencies or adjustments in respect of Taxes payable by Enertec or the
Enertec Subsidiaries have been claimed, proposed, assessed, or, to the best of
Enertec's knowledge, threatened. There is no material difference between the
amounts of the book basis and the tax basis of any assets or liabilities of
Enertec and the Enertec Subsidiaries that is not reflected in an appropriate
accrual of deferred tax asset or liability on the books of Enertec and the
Enertec Subsidiaries. The Enertec Disclosure Letter accurately sets forth the
last year for which Enertec's and the Enertec Subsidiaries' federal, provincial,
state and foreign income tax returns, respectively, have been assessed,
reassessed or audited and any years which are the subject of a pending audit by
any Governmental Entity. No waiver of any statute of limitations executed by
Enertec or an Enertec Subsidiary with respect to any Tax is in effect for any
period. There are no Tax liens on any assets of Enertec or the Enertec
Subsidiaries except for Taxes not yet currently due and those which could not
reasonably be expected to result in a Material Adverse Effect on Enertec.
Enertec and the Enertec Subsidiaries withheld all Taxes required to be withheld
in the course of their businesses, in respect of wages, salaries and other
payments to all employees, officers and directors, and in respect of payments to
any person who is not a resident of the country of the payor and timely paid all
such amounts withheld to the proper taxing authority, except where the failure
to do so could not reasonably be expected to result in a Material Adverse Effect
on Enertec. Enertec is not a "specified financial institution" as defined in the
ITA.
 
2.19 VOTE REQUIRED.

pursuant to relevant United States and Canadian securities statutes,
regulations, policies and rules (collectively, the "Veritas Securities
Reports"), all of which have complied at their respective dates of filing in all
material respects with all applicable requirements of such statutes,
regulations, policies and rules. None of the Veritas Securities Reports, at the
time filed or as subsequently amended, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein

mailed to the shareholders of Veritas and VESI and at the time of the Veritas
Stockholders Meeting
                                      B-16

and the VESI Meeting (and, if filed, at the time the Form S-4 and Form S-3 are
declared effective), contain any untrue statement of a material fact or omit to

statements therein, in light of the circumstances under which they are made, not
misleading. The Joint Proxy Statement will comply as to form in all material
respects with the provisions of applicable United States and Canadian securities
laws and the rules and regulations of the SEC, the Commissions, the TSE and the
NYSE.

aggregate, would not have a Material Adverse Effect on Veritas.
 
3.9 LITIGATION; INVESTIGATIONS.
 
     There is no claim, action, suit or proceeding pending or, to the knowledge
of Veritas, threatened, which would, if adversely determined, individually or in
the aggregate, have a Material Adverse Effect on Veritas, nor is there any
judgment, decree, injunction, rule or order of any Governmental Entity or
arbitrator outstanding against Veritas or any of the Veritas Subsidiaries
having, or which, insofar as reasonably can be foreseen, in the future could
have, any such effect. To the knowledge of Veritas, there is no investigation
pending or threatened against Veritas or any of the Veritas Subsidiaries before
any Governmental Entity.

minor defects as to not substantially interfere with the continued use thereof
in the conduct of normal operations.
 
3.16 ENVIRONMENTAL MATTERS.
 
     (a)   Environmental Conditions.  There are no environmental conditions or
circumstances, such as the presence or release of any hazardous substance, on
any property presently or previously owned or leased by Veritas or the Veritas
Subsidiaries that could result in a Material Adverse Effect on Veritas;
 
     (b)   Permits, etc.  Veritas and the Veritas Subsidiaries have in full
force and effect all material environmental permits, licenses, approvals and
other authorizations required to conduct their operations and are operating in
material compliance thereunder;

other federal, provincial, state or local law, statute, ordinance, rule,
regulation, order or notice requirement pertaining to (i) the condition or
protection of air, groundwater, surface water, soil, or other environmental
media, (ii) the environment, including natural resources or any activity which
affects the environment, or (iii) the regulation of any pollutants,
contaminants, waste, substances (whether or not hazardous or toxic), including,
without limitation, the Applicable Environmental Laws, except for violations
which, either singly or in the aggregate, would not result in a Material Adverse
Effect on Veritas;
 
     (d)   Past Compliance.  None of the operations or assets of Veritas or the
Veritas Subsidiaries has ever been conducted or used by Veritas or the Veritas
Subsidiaries in such a manner as to constitute a violation of any of the
Applicable Environmental Laws, except for violations which, either singly or in
the aggregate, would not result in a Material Adverse Effect on Veritas;
 
     (e)   Environmental Claims.  No notice has been served on Veritas or any
Veritas Subsidiaries from any entity, Governmental Entity or individual
regarding any existing, pending or threatened investigation or inquiry related
to alleged violations under any Applicable Environmental Laws, or regarding any
claims for remedial obligations or contribution under any Applicable
Environmental Laws, other than any of the foregoing which, either singly or in
the aggregate, would not result in a Material Adverse Effect on Veritas; and
 
     (f)   Renewals.  Veritas does not know of any reason why it would not be
able to renew any of the permits, licenses, or other authorizations required
pursuant to any Applicable Environmental Laws to operate and use any of Veritas'
or the Veritas Subsidiaries' assets for their current purposes and uses.
 
3.17 COMPLIANCE WITH OTHER LAWS.
 
     Neither Veritas nor any Veritas Subsidiary is in violation of or in default
with respect to, or in alleged violation of or alleged default with respect to
any other applicable law or any applicable rule, regulation, or any writ or
decree of any court or any Governmental Entity, or delinquent with respect to
any report required to be filed with any Governmental Entity, except for
violations which, either singly or in the aggregate, do not and are not expected
to result in a Material Adverse Effect on Veritas.
 
3.18 TAXES.
 
     Taxes.  Except with respect to failures which, in the aggregate, would not
result in a Material Adverse Effect on Veritas: (a) proper, complete and
accurate federal, provincial, state, local and foreign returns of all Taxes and
any and all other tax returns, declarations, reports, information returns,
statements and estimates have been filed with appropriate Governmental Entities,
domestic and foreign, by Veritas and each of the Veritas Subsidiaries, as
applicable, for each period for which any returns, declarations, reports,
information returns, statements or estimates were due (taking into account any
extensions of time to file before the date hereof); (b) all
                                      B-20
<PAGE>   204
 
Taxes shown by such returns, declarations, reports, information returns, or
statements to be payable and any other Taxes due and payable have been paid
other than those being contested in good faith by Veritas or a Veritas
Subsidiary and indicated in the Veritas Disclosure Letter; and (c) the tax
provision reflected in Veritas' financial statements is adequate, in accordance
with Canadian or United States (as the case may be) generally accepted
accounting principles, to cover liabilities of Veritas and the Veritas
Subsidiaries for all unpaid Taxes applicable to Veritas and the Veritas
Subsidiaries or their assets or businesses. Other than as reflected in Veritas'
financial statements, Veritas and the Veritas Subsidiaries have not received any
written notice of reassessment or any other notification of imposition of Taxes
from any Governmental Entity and no material Tax liability has been assessed,
proposed to be assessed, incurred or accrued, and no deficiencies or adjustments
in respect of Taxes payable by Veritas or the Veritas Subsidiaries have been
claimed, proposed, assessed, or, to the best of Veritas' knowledge, threatened.
There is no material difference between the amounts of the book basis and the
tax basis of any assets or liabilities of Veritas and the Veritas Subsidiaries
that is not reflected in an appropriate accrual of deferred tax asset or
liability on the books of Veritas and the Veritas Subsidiaries. The Veritas
Disclosure Letter accurately sets forth the last year for which Veritas' and the
Veritas Subsidiaries' federal, provincial, state and foreign income tax returns,
respectively, have been assessed, reassessed or audited and any years which are
the subject of a pending audit by any Governmental Entity. No waiver of any
statute of limitations executed by Veritas or an Veritas Subsidiary with respect
to any Tax is in effect for any period. There are no Tax liens on any assets of
Veritas or the Veritas Subsidiaries except for Taxes not yet currently due and
those which could not reasonably be expected to result in a Material Adverse
Effect on Veritas. Veritas and the Veritas Subsidiaries withheld all Taxes
required to be withheld in the course of their businesses, in respect of wages,
salaries and other payments to all employees, officers and directors, and in
respect of payments to any person who is not a resident of the country of the
payor and timely paid all such amounts withheld to the proper taxing authority,
except where the failure to do so could not reasonably be expected to result in
a Material Adverse Effect on Veritas. Veritas is not a "specified financial
institution" as defined in the ITA.
 
3.19 VOTE REQUIRED.
 
     At separate stockholders meetings at which the applicable quorums are
present, the affirmative vote of the holders of a majority of the issued and
outstanding shares of Veritas Common Stock and the affirmative vote of the
holders of two-thirds of the Exchangeable Shares present is necessary to approve
the Restated Veritas Charter in the case of Veritas and the Arrangement in the
case of VESI.
 
3.20 YEAR 2000.
 
     Veritas has initiated a review of the implications of the Year 2000 on its
business and processes, including an evaluation of key operating and information
systems, field operations and third parties and confirms the public disclosure
provided by it in respect thereof.
 
3.21 BROKERS AND FINDERS.
 
     None of Veritas or any of the Veritas Subsidiaries nor any of their
respective directors, officers or employees has employed any broker or finder or
incurred any liability for any financial advisory fees, brokerage fees,
commissions or similar payments in connection with the transactions contemplated
by this Agreement.
 
3.22 DISCLOSURE.
 
     No representation or warranty made by Veritas or VESI in this Agreement,
nor any document, written information, statement, financial statement,
certificate or Exhibit prepared and furnished or to be prepared and furnished by
Veritas or VESI or their representatives pursuant hereto or in connection with
the transactions contemplated hereby, when taken together, contained any untrue
statement of a material fact when made, or omitted to state a material fact
necessary to make the statements or facts contained herein or therein not
misleading in light of the circumstances under which they were furnished.

3.23 RESTRICTIONS ON BUSINESS ACTIVITIES.
 
     There is no material agreement, judgment, injunction, order or decree
binding upon Veritas or any Veritas Subsidiary that has or could reasonably be
expected to have the effect of prohibiting or materially impairing any business
practice of Veritas or any Veritas Subsidiary, any acquisition of property by
Veritas or any Veritas Subsidiary or the conduct of business by Veritas or any
Veritas Subsidiary as currently conducted.
 
3.24 BOOKS AND RECORDS.
 
     The books, records and accounts of Veritas and the Veritas Subsidiaries (a)
have been maintained in accordance with good business practices on a basis
consistent with prior years, (b) are stated in reasonable detail and accurately
and fairly reflect the transactions and dispositions of the assets of Veritas
and the Veritas Subsidiaries and (c) accurately and fairly reflect the basis for
the Veritas financial statements. Veritas has devised and maintains a system of
internal accounting controls sufficient to provide reasonable assurances that
(a) transactions are executed in accordance with management's general or
specific authorization; and (b) transactions are recorded as necessary (i) to
permit preparation of financial statements in conformity with United States
generally accepted accounting principles or any other criteria applicable to
such statements and (ii) to maintain accountability for assets.
 
3.25 POOLING MATTERS.
 
     To the knowledge of Veritas based on consultation with its independent
auditors, neither Veritas nor any of its Affiliates has taken or agreed to take
any action that, without giving effect to any action taken or agreed to be taken
by Enertec or any of its Affiliates, would prevent Enertec from accounting for
the business combination to be effected by the Arrangement as a pooling of
interests under United States generally accepted accounting principles.

financial arrangements have been made, which the Enertec Board determines in
good faith (after consultation with its financial advisors, and after receiving
a written opinion of outside legal counsel to the effect that the Enertec Board

officer or employee who has an Executive Termination Contract to enter into a
non-compete agreement with Veritas for a term equal to the duration specified by
the respective Executive Termination Contract in determining the severance of
such director, officer or employee and on such other terms as are satisfactory

be pending. There shall be no order, decree or ruling by any Governmental Entity
or threat thereof, or any statute, rule, regulation or order enacted, entered,
enforced or deemed applicable to the Arrangement, which would prohibit or render
illegal the transactions contemplated by this Agreement;
 
     (g)   Court Approval.  The Court shall have issued its final order
approving the Arrangement in form and substance satisfactory to Enertec and
Veritas (such approvals not to be unreasonably withheld or delayed by Enertec or
Veritas) and reflecting the terms hereof;
 
     (h)   Commissions, etc.  All necessary orders shall have been obtained from
the Commissions and other relevant United States and Canadian securities
regulatory authorities in connection with the Arrangement. All waiting periods
required by HSR shall have expired with respect to the transactions contemplated
by this Agreement, or early termination with respect thereto shall have been
obtained without the imposition of any governmental request or order requiring
the sale or disposition or holding separate (through a trust or otherwise) of
particular assets or businesses of Veritas, VESI or Enertec. Enertec, Veritas
and VESI shall each have filed all notices and information (if any) required
under Part IX of the Competition Act (Canada) and the applicable waiting periods
and any extensions thereof shall have expired or the parties shall have received
an Advance Ruling Certificate pursuant to Section 102 of the Competition Act
(Canada) setting out that the Director under such Act is satisfied he would not
have sufficient grounds on which to apply for an order in respect of the
Arrangement. The Arrangement shall have received the allowance or approval or
deemed allowance or approval by the responsible Minister under the Investment
Canada Act in respect of the Arrangement, to the extent such allowance or
approval is required, on terms and conditions satisfactory to the parties,
acting reasonably;
 
     (i)   SEC Filings.  Each of the Form S-4 and Form S-3, if required to be
filed, shall have been declared effective under the Securities Act and shall not
be the subject of any stop-order or proceedings seeking a stop-order and the
Joint Proxy Statement shall on the Closing Date not be subject to any similar
proceedings commenced or threatened by the SEC or the Commissions;
 
     (j)   Certificates and Resolutions.  Veritas shall have received such other
certificates and resolutions of Enertec as may be reasonably required in
connection with the consummation of this Agreement; and
 
     (k)   Pooling Matters.  Veritas shall have received from KPMG, LLP and
Pricewaterhouse Coopers LLP an opinion, in form and substance satisfactory to
Veritas and Enertec, acting reasonably, that the Arrangement will be treated as
a "pooling of interests" for purposes of United States generally accepted
accounting principles. In addition, no event shall have occurred which would
establish with reasonable certainty that the Arrangement will not be treated as
a "pooling of interests" for purposes of United States generally accepted
accounting principles.

     This Agreement may be terminated at any time prior to the Effective Time,
whether before or after approval of the transactions contemplated hereby by the
stockholders of Veritas, VESI or Enertec, as follows:
 
     (a)   by mutual agreement of Enertec and Veritas;
 
     (b)   by Enertec, if there has been a breach by Veritas or VESI of any
representation, warranty, covenant or agreement set forth in this Agreement on
the part of Veritas or VESI, or if any representation or warranty of Veritas or
VESI shall have become untrue, in either case which has or can reasonably be
expected to have a Material Adverse Effect on Veritas, and which Veritas or VESI
fails to cure within 15 business days after written notice thereof from Enertec
(except that no cure period shall be provided for a breach by Veritas or VESI
which by its nature cannot be cured);
 
     (c)   by Veritas, if there has been a breach by Enertec of any
representation, warranty, covenant or agreement set forth in this Agreement on
the part of Enertec, or if any representation or warranty of Enertec shall have
become untrue, in either case which has or can reasonably be expected to have a
Material Adverse Effect on
 
                                      B-28
<PAGE>   212
 
Enertec, and which Enertec fails to cure within 15 business days after written
notice thereof from Veritas (except that no cure period shall be provided for a
breach by Enertec which by its nature cannot be cured);
 
     (d)   by either Veritas or Enertec if the shareholders of Enertec and of
VESI do not approve the Arrangement (and the other matters to be approved at
such meetings as provided in Section 7.1 hereof) at the Enertec Meeting and the
VESI Meeting, as applicable, or the stockholders of Veritas do not approve at
the Veritas Stockholders Meeting the matters to be approved at such meeting as
provided in Section 7.1 hereof;
 
     (e)   by either Veritas or Enertec, if all the conditions for Closing the
Arrangement expressed to be in its favour shall not have been satisfied or
waived on or before 5:00 p.m., Houston, Texas time on August 15, 1999, other
than as a result of a breach of this Agreement by the terminating party;
 
     (f)   by either Veritas or Enertec if any suit, action, or other proceeding
shall be pending or threatened by any United States or Canadian federal,
provincial or state government before any Governmental Entity, in which it is
sought to restrain, prohibit, or otherwise affect the consummation of the
transactions contemplated hereby; or
 
     (g)   by Enertec, if (i) the Enertec Board determines in good faith (after
consultation with its financial advisors, and after receiving the written
opinion of its outside legal counsel), that it is required by its fiduciary
duties to recommend to the Enertec shareholders that they vote against the
Arrangement and approve instead a Superior Proposal, (ii) Enertec shall have
given notice to Veritas advising Veritas that Enertec has received a Superior
Proposal from a third party, specifying the terms and conditions of such
Superior Proposal and that Enertec intends to terminate this Agreement in
accordance with this Section 6.1(g) and (iii) either (A) Veritas shall not have
revised its takeover proposal within five business days after the date on which
such notice is deemed to have been given to Veritas, or (B) if Veritas within
such period shall have revised its takeover proposal, the Enertec Board, after
receiving advice from Enertec's financial advisors, shall have determined in its
good faith judgment that the third party's Acquisition Transaction is superior
to Veritas' revised takeover proposal.

     Any termination of this Agreement under Section 6.1 above will be effective
by the delivery of written notice by the terminating party to the other party
hereto.

as provided in Section 6.1, this Agreement shall forthwith become void and have
no effect, and there shall be no liability or obligation on the part of Veritas
or Enertec or their respective officers or directors, except that (i) the
provisions of the Confidentiality Agreement dated January 25, 1999 shall survive
any such termination and abandonment, and (ii) no party shall be released or
relieved from any liability arising from the willful breach by such party of any
of its representations, warranties, covenants or agreements as set forth in this
Agreement.

        "Insolvency Event" means the institution by Veritas of any proceeding to
        be adjudicated a bankrupt or insolvent or to be dissolved or wound-up,
        or the consent of Veritas to the institution of bankruptcy, insolvency,
        dissolution or winding-up proceedings against it, or the filing of a
        petition, answer or consent seeking dissolution or winding-up under any
        bankruptcy, insolvency or analogous laws, including without limitation
        the Companies' Creditors Arrangement Act (Canada) and the Bankruptcy and
        Insolvency Act (Canada), and the failure by Veritas to contest in good
        faith any such proceedings commenced in respect of Veritas within 15
        days of becoming aware thereof, or the consent by Veritas to the filing
        of any such petition or to the appointment of a receiver, or the making
        by Veritas of a general assignment for the benefit of creditors, or the
        admission in writing by Veritas of its inability to pay its debts
        generally as they become due, or Veritas not being permitted, pursuant
        to liquidity or solvency requirements of applicable law, to redeem any
        Exchangeable Shares in accordance with the terms thereof or to redeem
        any shares of any series of Class A Exchangeable Shares of the
        Corporation in accordance with the terms thereof.";
 
     (e)   Each of the Enertec Common Shares (other than Enertec Common Shares
           held by holders who have exercised their rights of dissent in
           accordance with Section 3.1 hereof and who are ultimately entitled to
           be paid the fair value for such shares) will be transferred to VESI
           in consideration for a number of Series 1 Exchangeable Shares at an
           exchange ratio equal to 0.345 of a Series 1 Exchangeable Share for
           each Enertec Common Share (the "Exchange Ratio"), and each such
           holder of Enertec Common Shares will receive that whole number of
           Series 1 Exchangeable Shares resulting from the transfer of such
           holder's Enertec Common Shares. In lieu of fractional Series 1
           Exchangeable Shares, each holder of an Enertec Common Share who
           otherwise would be entitled to receive a fraction of a Series 1
           Exchangeable Share shall be paid by VESI an amount determined in
           accordance with Section 4.3 hereof;
 
     (f)   Upon the transfer of shares referred to in Section 2.1(e) above:
 
        (i)    each holder of an Enertec Common Share shall cease to be such a
               holder, shall have his name removed from the register of holders
               of Enertec Common Shares and shall become a holder of the number
               of fully paid Series 1 Exchangeable Shares to which he is
               entitled as a result of the transfer referred to in Section
               2.1(e) above and such holder's name shall be added to the
               register of holders of Series 1 Exchangeable Shares accordingly;
 
        (ii)   VESI shall become the legal and beneficial owner of all of the
               Enertec Common Shares so transferred; and
 
        (iii)  the Shareholders Rights Plan Agreement between Enertec and
               Montreal Trust Company of Canada made as of December 11, 1997, as
               amended and restated as of March 6, 1998, and all outstanding
               Rights (as defined in such agreement) will be terminated, void
               and of no further force or effect;
 
     (g)   Holders of Enertec Common Shares shall be entitled to make an income
           tax election pursuant to section 85 of the ITA with respect to the
           transfer of their Enertec Common Shares to VESI referred to in
           Section 2.1(e) by providing two signed copies of the necessary
           election forms to VESI within 90 days following the Effective Date,
           duly completed with the details of the number of shares transferred
           and the applicable agreed amounts for the purposes of such elections.
           Thereafter, subject to the election forms complying with the
           provisions of the ITA, the forms will be signed by VESI and returned
           to such holders of Enertec Common Shares for filing with Revenue
           Canada, Taxation;
 
     (h)   Veritas shall issue to and deposit with the Depositary the Voting
           Share (as defined in the Voting and Exchange Trust Agreement), in
           consideration of the payment to Veritas of U.S. $1, to be thereafter
 
                                       D-4
<PAGE>   228
 
held by the Depositary as trustee for and on behalf of, and for the use and
benefit of, the holders of the Series 1 Exchangeable Shares, in accordance with
the Voting and Exchange Trust Agreement; and
 
     (i)   Each of the then outstanding Options will and without any further
           action on the part of any Optionholder, be exchanged for an option
           (collectively, the "Veritas Options") under the Third Amended and
           Restated 1992 Employee Non-qualified Stock Option Plan (the "Veritas
           Option Plan") to purchase that number of shares of Veritas Common
           Stock determined by multiplying the number of Enertec Common Shares
           subject to such Option at the Effective Time by the Exchange Ratio,
           at an exercise price per share of Veritas Common Stock equal to the
           exercise price per share of such Option immediately prior to the
           Effective Time, divided by the Exchange Ratio. Such option price
           shall be converted into a United States dollar equivalent based on
           the rate of exchange applicable at the Effective Time as stated in
           that edition of The Wall Street Journal next published after the
           Effective Time. If the foregoing calculation results in an exchanged
           Option being exercisable for a fraction of a share of Veritas Common
           Stock, then the number of shares of Veritas Common Stock subject to
           such Option will be rounded down to the nearest whole number of
           shares, and the total exercise price for the Veritas Option will be
           reduced by the exercise price of the fractional share. Each Veritas
           Option shall be:
 
        (i)    fully vested immediately after the Effective Time; and
 
        (ii)   for a term commencing at the Effective Time and ending as
               follows:
 
             (A)  for each Optionholder who:
 
                  (1)   is an Enertec director, officer or employee as at the
                        Effective Time (a "Current Optionholder"); and
 
                  (2)   after the Effective Time is employed or retained by
                        Veritas, Enertec or one of their Subsidiaries,
 
                  on the date as set forth in subsections 5(b) and (d) of the
                  Enertec Option Plan;
 
             (B)  for each Current Optionholder who at the Effective Time is not
                  retained as a director, officer or employee of Veritas,
                  Enertec or one of their Subsidiaries, on the date that is the
                  first business day on or immediately after the date that is 90
                  days after the later of the Effective Date and the date such
                  director, officer or employee is terminated; or
 
             (C)  notwithstanding the provisions of (A) and (B) above, the
                  Enertec Option Plan or the Veritas Option Plan, for each
                  Current Optionholder with an executive termination contract,
                  on the current expiry date of such Option (the sixth
                  anniversary date).
 
     The term, exerciseability, and all other terms and conditions of the
     Enertec Options exchanged in accordance with this Section 2.1(i) will
     otherwise be unchanged by the provisions of this Section 2.1(i) and shall
     operate in accordance with their terms and the Veritas Option Plan shall be
     amended accordingly as required.

                               RIGHTS OF DISSENT
 
3.1 RIGHTS OF DISSENT.  Holders of Enertec Common Shares or Options and holders
of Exchangeable Shares may exercise rights of dissent with respect to such
shares or options pursuant to and in the manner set forth in section 184 of the
ABCA and this Section 3.1 (the "Dissent Procedures") in connection with the
Arrangement and holders who duly exercise such rights of dissent and who:
 
     (a)   are ultimately entitled to be paid the fair value for their Enertec
           Common Shares, Options or Exchangeable Shares, as the case may be,
           shall be deemed to have transferred such Enertec Common Shares or
           Options to Enertec or such Exchangeable Shares to VESI, as the case
           may be, for cancellation on the Effective Date; or
 
                                       D-5

     (b)   are ultimately not entitled, for any reason, to be paid the fair
           value for their Enertec Common Shares, Options or Exchangeable
           Shares, as the case may be, shall be deemed to have participated in
           the Arrangement on the same basis as any non-dissenting holder of
           Enertec Common Shares, Options or Exchangeable Shares, as the case
           may be,
 
but in no case shall Enertec be required to recognize such holders as holders of
Enertec Common Shares or Options or shall VESI be required to recognize such
holders as holders of Exchangeable Shares on and after the Effective Date, and
the names of such holders shall be deleted from the applicable register of
holders of Enertec or VESI securities on the Effective Date.
 
                                   ARTICLE 4
                       CERTIFICATES AND FRACTIONAL SHARES
 
4.1 ISSUANCE OF CERTIFICATES REPRESENTING SERIES 1 EXCHANGEABLE SHARES.  At or
promptly after the Effective Time, VESI shall deposit with the Depositary, for
the benefit of the holders of Enertec Common Shares transferred pursuant to
Section 2.1(e), certificates representing the Series 1 Exchangeable Shares
issued pursuant to Section 2.1(e) upon the transfer of outstanding Enertec
Common Shares. Upon surrender to the Depositary for cancellation of a
certificate which immediately prior to the Effective Time represented
outstanding Enertec Common Shares that were transferred for Series 1
Exchangeable Shares, together with such other documents and instruments as would
have been required to effect the transfer of the shares formerly represented by
such certificate under the ABCA and the by-laws of Enertec and such additional
documents and instruments as the Depositary may reasonably require, the holder
of such surrendered certificate shall be entitled to receive in consideration
therefor, and the Depositary shall deliver to such holder, a certificate
representing that number (rounded down to the nearest whole number) of Series 1
Exchangeable Shares which such holder has the right to receive (together with
any dividends or distributions with respect thereto pursuant to Section 4.2 and
any cash in lieu of fractional Series 1 Exchangeable Shares pursuant to Section
4.3), and the certificate so surrendered shall forthwith be cancelled. In the
event of a transfer of ownership of Enertec Common Shares which is not
registered in the transfer records of Enertec, a certificate representing the
proper number of Series 1 Exchangeable Shares may be issued to a transferee if
the certificate representing such Enertec Common Shares is presented to the
Depositary, accompanied by all documents required to evidence and effect such
transfer. Until surrendered as contemplated by this Section 4.1, each
certificate which immediately prior to the Effective Time represented
outstanding Enertec Common Shares that were transferred in consideration for
Series 1 Exchangeable Shares shall be deemed at any time after the Effective
Time to represent only the right to receive upon such surrender (a) the
certificate representing Series 1 Exchangeable Shares as contemplated by this
Section 4.1, (b) a cash payment in lieu of any fractional Series 1 Exchangeable
Shares as contemplated by Section 4.3 and (c) any dividends or distributions
with a record date after the Effective Time theretofore paid or payable with
respect to Series 1 Exchangeable Shares as contemplated by Section 4.2.
 
4.2 DISTRIBUTIONS WITH RESPECT TO UNSURRENDERED CERTIFICATES.  No dividends or
other distributions declared or made after the Effective Time with respect to
Series 1 Exchangeable Shares with a record date after the Effective Time shall
be paid to the holder of any unsurrendered certificate which, immediately prior
to the Effective Time, represented outstanding Enertec Common Shares that were
transferred pursuant to Section 2.1, and no cash payment in lieu of fractional
shares shall be paid to any such holder pursuant to Section 4.3, (and no
interest will be earned or payable on these proceeds) unless and until such
certificate shall be surrendered in accordance with Section 4.1. Subject to
applicable law and to Section 4.5, at the time of such surrender of any such
certificate (or, in the case of clause (c) below, at the appropriate payment
date), there shall be paid to the record holder of the certificates representing
whole Series 1 Exchangeable Shares without interest, (a) the amount of any cash
payable in lieu of a fractional Series 1 Exchangeable Share to which such holder
is entitled pursuant to Section 4.3, (b) the amount of dividends or other
distributions with a record date after the Effective Time theretofore paid with
respect to such whole Series 1 Exchangeable Share, and (c) the amount of
dividends or other distributions with a record date after the Effective Time but
prior to surrender and a payment date subsequent to surrender payable with
respect to such whole Series 1 Exchangeable Share.
 
                                       D-6
<PAGE>   230
 
4.3 NO FRACTIONAL SHARES.  No certificates or scrip representing fractional
Series 1 Exchangeable Shares shall be issued upon the surrender for transfer of
certificates pursuant to Section 4.1 and no dividend, stock split or other
change in the capital structure of VESI shall relate to any such fractional
security and such fractional interests shall not entitle the owner thereof to
vote or to exercise any rights as a security holder of VESI. In lieu of any such
fractional securities, each person entitled to a fractional interest in a Series
1 Exchangeable Share will receive an amount of cash (rounded to the nearest
whole cent), without interest, equal to the product of (a) such fraction,
multiplied by (b) the Average Closing Price of the Veritas Common Stock, such
amount to be provided to the Depositary by VESI upon request.
 
4.4 LOST CERTIFICATES.  If any certificate which immediately prior to the
Effective Time represented outstanding Enertec Common Shares that were
transferred pursuant to Section 2.1 has been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the person claiming such certificate to
be lost, stolen or destroyed, the Depositary will issue in exchange for such
lost, stolen or destroyed certificate, certificates representing Series 1
Exchangeable Shares (and any dividends or distributions with respect thereto and
any cash pursuant to Section 4.3) deliverable in respect thereof as determined
in accordance with Section 2.1. When authorizing such payment in exchange for
any lost, stolen or destroyed certificate, the person to whom certificates
representing Series 1 Exchangeable Shares are to be issued shall, as a condition
precedent to the issuance thereof, give a bond satisfactory to VESI, Veritas and
VESI's transfer agent (the "Transfer Agent"), as the case may be, in such sum as
VESI may direct or otherwise indemnify VESI or Veritas in a manner satisfactory
to VESI and the Transfer Agent against any claim that may be made against VESI,
Veritas or the Transfer Agent with respect to the certificate alleged to have
been lost, stolen or destroyed.
 
4.5 EXTINGUISHMENT OF RIGHTS. Any certificate which immediately prior to the
Effective Time represented outstanding Enertec Common Shares that were
transferred pursuant to Section 2.1 and has not been deposited, with all other
instruments required by Section 4.1, on or prior to the tenth anniversary of the
Effective Date shall cease to represent a claim or interest of any kind or
nature as a shareholder of VESI. On such date, the Series 1 Exchangeable Shares
to which the former registered holder of the certificate referred to in the
preceding sentence was ultimately entitled shall be deemed to have been
surrendered to VESI together with all entitlements to dividends, distributions
and interests thereon held for such former registered holder for no
consideration.
 
                                   ARTICLE 5
       CERTAIN RIGHTS OF VERITAS TO ACQUIRE SERIES 1 EXCHANGEABLE SHARES
 
5.1 VERITAS LIQUIDATION CALL RIGHT.
 
     (a)   Veritas shall have the overriding right (the "Liquidation Call
           Right"), in the event of and notwithstanding the proposed
           liquidation, dissolution or winding-up of VESI pursuant to Article 5
           of the Series 1 Exchangeable Share Provisions, to purchase from all
           but not less than all of the holders (other than Veritas and any
           Subsidiary thereof) of Series 1 Exchangeable Shares on the
           Liquidation Date all but not less than all of the Series 1
           Exchangeable Shares held by each such holder on payment by Veritas to
           the holder of the Series 1 Exchangeable Share Price applicable on the
           last Business Day prior to the Liquidation Date (the "Liquidation
           Call Purchase Price"). In the event of the exercise of the
           Liquidation Call Right by Veritas, each holder shall be obligated to
           sell all the Series 1 Exchangeable Shares held by the holder to
           Veritas on the Liquidation Date on payment by Veritas to the holder
           of the Liquidation Call Purchase Price for each such share.
 
     (b)   To exercise the Liquidation Call Right, Veritas must notify VESI's
           Transfer Agent in writing, as agent for the holders of Series 1
           Exchangeable Shares, and VESI of Veritas' intention to exercise such
           right at least 55 days before the Liquidation Date in the case of a
           voluntary liquidation, dissolution or winding-up of VESI and at least
           five Business Days before the Liquidation Date in the case of an
           involuntary liquidation, dissolution or winding-up of VESI. The
           Transfer Agent will notify the holders of Series 1 Exchangeable
           Shares as to whether or not Veritas has exercised the Liquidation
           Call Right forthwith after the expiry of the date by which the same
           may be exercised by Veritas. If Veritas exercises the Liquidation
           Call Right, on the Liquidation Date Veritas will purchase and the
           holders
 
                                       D-7
<PAGE>   231
 
will sell all of the Series 1 Exchangeable Shares then outstanding for a price
per share equal to the Liquidation Call Purchase Price.
 
     (c)   For the purposes of completing the purchase of the Series 1
           Exchangeable Shares pursuant to the Liquidation Call Right, Veritas
           shall deposit with the Transfer Agent, on or before the Liquidation
           Date, the Series 1 Exchangeable Share Consideration representing the
           total Liquidation Call Purchase Price. In connection with payment of
           the Liquidation Call Purchase Price, Veritas shall be entitled to
           liquidate some of the Veritas Common Stock that would otherwise be
           deliverable to the particular holder of Series 1 Exchangeable Shares
           in order to fund any statutory withholding tax obligation. Provided
           that such Series 1 Exchangeable Share Consideration has been so
           deposited with the Transfer Agent, on and after the Liquidation Date
           the rights of each holder of Series 1 Exchangeable Shares will be
           limited to receiving such holder's proportionate part of the total
           Liquidation Call Purchase Price payable by Veritas without interest
           upon presentation and surrender by the holder of certificates
           representing the Series 1 Exchangeable Shares held by such holder and
           the holder shall on and after the Liquidation Date be considered and
           deemed for all purposes to be the holder of the Veritas Common Stock
           delivered to it. Upon surrender to the Transfer Agent of a
           certificate or certificates representing Series 1 Exchangeable
           Shares, together with such other documents and instruments as may be
           required to effect a transfer of Series 1 Exchangeable Shares under
           the ABCA and the by-laws of VESI and such additional documents and
           instruments as the Transfer Agent may reasonably require, the holder
           of such surrendered certificate or certificates shall be entitled to
           receive in exchange therefor, and the Transfer Agent on behalf of
           Veritas shall deliver to such holder, the Series 1 Exchangeable Share
           Consideration to which the holder is entitled. If Veritas does not
           exercise the Liquidation Call Right in the manner described above, on
           the Liquidation Date the holders of the Series 1 Exchangeable Shares
           will be entitled to receive in exchange therefor the liquidation
           price otherwise payable by VESI in connection with the liquidation,
           dissolution or winding-up of VESI pursuant to Article 5 of the Series
           1 Exchangeable Share Provisions. Notwithstanding the foregoing, until
           such Series 1 Exchangeable Share Consideration is delivered to the
           holder, the holder shall be deemed to still be a holder of Series 1
           Exchangeable Shares for purposes of all voting rights with respect
           thereto under the Voting and Exchange Trust Agreement.
 
5.2 VERITAS REDEMPTION CALL RIGHT.
 
     (a)   Veritas shall have the overriding right (the "Redemption Call
           Right"), notwithstanding the proposed redemption of the Series 1
           Exchangeable Shares by VESI pursuant to Article 7 of the Series 1
           Exchangeable Share Provisions, to purchase from all but not less than
           all of the holders (other than Veritas or any Subsidiary thereof) of
           Series 1 Exchangeable Shares on the Automatic Redemption Date all but
           not less than all of the Series 1 Exchangeable Shares held by each
           such holder on payment by Veritas to the holder of the Series 1
           Exchangeable Share Price applicable on the last Business Day prior to
           the Automatic Redemption Date (the "Redemption Call Purchase Price").
           In the event of the exercise of the Redemption Call Right by Veritas,
           each holder shall be obligated to sell all the Series 1 Exchangeable
           Shares held by the holder to Veritas on the Automatic Redemption Date
           on payment by Veritas to the holder of the Redemption Call Purchase
           Price for each such share.
 
     (b)   To exercise the Redemption Call Right, Veritas must notify the
           Transfer Agent in writing, as agent for the holders of Series 1
           Exchangeable Shares, and VESI of Veritas's intention to exercise such
           right at least 125 days before the Automatic Redemption Date. The
           Transfer Agent will notify the holders of the Series 1 Exchangeable
           Shares as to whether or not Veritas has exercised the Redemption Call
           Right forthwith after the date by which the same may be exercised by
           Veritas. If Veritas exercises the Redemption Call Right, on the
           Automatic Redemption Date Veritas will purchase and the holders will
           sell all of the Series 1 Exchangeable Shares then outstanding for a
           price per share equal to the Redemption Call Purchase Price.
 
     (c)   For the purposes of completing the purchase of the Series 1
           Exchangeable Shares pursuant to the Redemption Call Right, Veritas
           shall deposit with the Transfer Agent, on or before the Automatic
           Redemption Date, the Series 1 Exchangeable Share Consideration
           representing the total Redemption
                                       D-8
<PAGE>   232
 
        Call Purchase Price. In connection with payment of the Redemption Call
        Purchase Price, Veritas shall be entitled to liquidate some of the
        Veritas Common Stock that would otherwise be deliverable to the
        particular holder of Series 1 Exchangeable Shares in order to fund any
        statutory withholding tax obligation. Provided that such Series 1
        Exchangeable Share Consideration has been so deposited with the Transfer
        Agent, on and after the Automatic Redemption Date the rights of each
        holder of Series 1 Exchangeable Shares will be limited to receiving such
        holder's proportionate part of the total Redemption Call Purchase Price
        payable by Veritas upon presentation and surrender by the holder of
        certificates representing the Series 1 Exchangeable Shares held by such
        holder and the holder shall on and after the Automatic Redemption Date
        be considered and deemed for all purposes to be the holder of the
        Veritas Common Stock delivered to such holder. Upon surrender to the

office of the Corporation or at any office of the Transfer Agent as may be
specified by the Corporation by notice to the holders of the Series 1
Exchangeable Shares. Payment of the total Liquidation Amount for such Series 1
Exchangeable Shares shall be made by delivery to each holder, at the address of
the holder recorded in the securities register of the Corporation for the Series
1 Exchangeable Shares or by holding for pick up by the holder at the registered
office of the Corporation or at any office of the Transfer Agent as may be
specified by the Corporation by notice to the holders of Series 1 Exchangeable
Shares, on behalf of the Corporation of the Series 1 Exchangeable Share
Consideration representing the total Liquidation Amount. On and after the
Liquidation Date, the holders of the Series 1 Exchangeable Shares shall cease to
be holders of such Series 1 Exchangeable Shares and shall not be entitled to
exercise any of the rights of holders in respect thereof, other than the right
to receive their proportionate part of the total Liquidation Amount, unless
payment of the total Liquidation Amount for such Series 1 Exchangeable Shares
shall not be made upon presentation and surrender of share certificates in
accordance with the foregoing provisions, in which case the rights of the
holders shall remain unaffected until the total Liquidation Amount has been paid
in the manner hereinbefore provided. The Corporation shall have the right at any
time on or after the Liquidation Date to deposit or cause to be deposited the
Series 1 Exchangeable Share Consideration in respect of the Series 1
Exchangeable Shares represented by certificates that have not at the Liquidation
Date been surrendered by the holders thereof in a custodial account or for safe
keeping, in the case of non-cash items, with any chartered bank or trust company
in Canada. Upon such deposit being made, the rights of the holders of Series 1
Exchangeable Shares after such deposit shall be limited to receiving their
proportionate part of the total Liquidation Amount for such Series 1
Exchangeable Shares so deposited, against presentation and surrender of the said
certificates held by them, respectively, in accordance with the foregoing
provisions. Upon such payment or deposit of such Series 1 Exchangeable Share
Consideration, the holders of the Series 1 Exchangeable Shares shall thereafter
be considered and deemed for all purposes to be the holders of the Veritas
Common Stock delivered to them. Notwithstanding the foregoing, until such Series
1 Exchangeable Share Consideration is delivered to the holder,
 
                                      D-15
<PAGE>   239
 
the holder shall be deemed to still be a holder of Series 1 Exchangeable Shares
for purposes of all voting rights with respect thereto under the Voting and
Exchange Trust Agreement.
 
5.3 After the Corporation has satisfied its obligations to pay the holders of
the Series 1 Exchangeable Shares the Liquidation Amount per Series 1
Exchangeable Share pursuant to Section 5.1 of these share provisions, such
holders shall not be entitled to share in any further distribution of the assets
of the Corporation.
 
                                   ARTICLE 6
              RETRACTION OF SERIES 1 EXCHANGEABLE SHARES BY HOLDER
 
6.1 A holder of Series 1 Exchangeable Shares shall be entitled at any time,
subject to the exercise by Veritas of the Retraction Call Right and otherwise
upon compliance with the provisions of this Article 6, to require the
Corporation to redeem any or all of the Series 1 Exchangeable Shares registered
in the name of such holder for an amount equal to the Series 1 Exchangeable
Share Price applicable on the last Business Day prior to the Retraction Date
(the "Retraction Price"). In connection with payment of the Retraction Price,
the Corporation shall be entitled to liquidate some of the Veritas Common Stock
that would otherwise be deliverable to the particular holder of Series 1
Exchangeable Shares in order to fund any statutory withholding tax obligation.
To effect such redemption, the holder shall present and surrender at the
registered office of the Corporation or at any office of the Transfer Agent as
may be specified by the Corporation by notice to the holders of Series 1
Exchangeable Shares the certificate or certificates representing the Series 1
Exchangeable Shares which the holder desires to have the Corporation redeem,
together with such other documents and instruments as may be required to effect
a transfer of Series 1 Exchangeable Shares under the Business Corporations Act
(Alberta) and the by-laws of the Corporation and such additional documents and
instruments as the Transfer Agent may reasonably require, and together with a
duly executed statement (the "Retraction Request") in the form of Schedule A
hereto or in such other form as may be acceptable to the Corporation:
 
     (i)    specifying that the holder desires to have all or any number
            specified therein of the Series 1 Exchangeable Shares represented by
            such certificate or certificates (the "Retracted Shares") redeemed
            by the Corporation;
 
     (ii)   stating the Business Day on which the holder desires to have the
            Corporation redeem the Retracted Shares (the "Retraction Date"),
            provided that the Retraction Date shall be not less than five
            Business Days nor more than 10 Business Days after the date on which
            the Retraction Request is received by the Corporation and further
            provided that, in the event that no such Business Day is specified
            by the holder in the Retraction Request, the Retraction Date shall
            be deemed to be the tenth Business Day after the date on which the
            Retraction Request is received by the Corporation; and
 
     (iii)  acknowledging the overriding right (the "Retraction Call Right") of
            Veritas to purchase all but not less than all the Retracted Shares
            directly from the holder and that the Retraction Request shall be
            deemed to be a revocable offer by the holder to sell the Retracted
            Shares to Veritas in accordance with the Retraction Call Right on
            the terms and conditions set out in Section 6.3 below.
 
6.2 Subject to the exercise by Veritas of the Retraction Call Right, upon
receipt by the Corporation or the Transfer Agent in the manner specified in
Section 6.1 hereof of a certificate or certificates representing the number of
Series 1 Exchangeable Shares which the holder desires to have the Corporation
redeem, together with a Retraction Request, and provided that the Retraction
Request is not revoked by the holder in the manner specified in Section 6.7, the
Corporation shall redeem the Retracted Shares effective at the close of business
on the Retraction Date and shall cause to be delivered to such holder the total
Retraction Price with respect to such shares. If only a part of the Series 1
Exchangeable Shares represented by any certificate are redeemed (or purchased by
Veritas pursuant to the Retraction Call Right), a new certificate for the
balance of such Series 1 Exchangeable Shares shall be issued to the holder at
the expense of the Corporation.
 
6.3 Upon receipt by the Corporation of a Retraction Request, the Corporation
shall immediately notify Veritas thereof. In order to exercise the Retraction
Call Right, Veritas must notify the Corporation in writing of its determination
to do so (the "Veritas Call Notice") within two Business Days of notification to
Veritas by the Corporation of the receipt by the Corporation of the Retraction
Request. If Veritas does not so notify the
                                      D-16
<PAGE>   240
 
Corporation within such two Business Day period, the Corporation will notify the
holder as soon as possible thereafter that Veritas will not exercise the
Retraction Call Right. If Veritas delivers the Veritas Call Notice within such
two Business Day time period, and provided that the Retraction Request is not
revoked by the holder in the manner specified in Section 6.7, the Retraction
Request shall thereupon be considered only to be an offer by the holder to sell
the Retracted Shares to Veritas in accordance with the Retraction Call Right. In
such event, the Corporation shall not redeem the Retracted Shares and Veritas
shall purchase from such holder and such holder shall sell to Veritas on the
Retraction Date the Retracted Shares for a purchase price (the "Purchase
Price ") per share equal to the Retraction Price per share. For the purposes of
completing a purchase pursuant to the Retraction Call Right, Veritas shall
deposit with the Transfer Agent, on or before the Retraction Date the Series 1
Exchangeable Share Consideration representing the total Purchase Price. In
connection with payment of the Purchase Price, Veritas shall be entitled to
liquidate some of the Veritas Common Stock that would otherwise be deliverable
to the particular holder of Series 1 Exchangeable Shares in order to fund any
statutory withholding tax obligation. Provided that such Series 1 Exchangeable
Share Consideration has been so deposited with the Transfer Agent, the closing
of the purchase and sale of the Retracted Shares pursuant to the Retraction Call
Right shall be deemed to have occurred as at the close of business on the
Retraction Date and, for greater certainty, no redemption by the Corporation of
such Retracted Shares shall take place on the Retraction Date. In the event that
Veritas does not deliver a Veritas Call Notice within such two Business Day
period or otherwise comply with these Series 1 Exchangeable Share provisions in
respect thereto, and provided that Retraction Request is not revoked by the
holder in the manner specified in Section 6.7, the Corporation shall redeem the
Retracted Shares on the Retraction Date and in the manner otherwise contemplated
in this Article 6.
 
6.4 The Corporation or Veritas, as the case may be, shall deliver or cause the
Transfer Agent to deliver to the relevant holder, at the address of the holder
recorded in the securities register of the Corporation for the Series 1
Exchangeable Shares or at the address specified in the holder's Retraction
Request or by holding for pick up by the holder at the registered office of the
Corporation or at any office of the Transfer Agent as may be specified by the
Corporation by notice to the holders of Series 1 Exchangeable Shares, the Series
1 Exchangeable Share Consideration representing the total Retraction Price or
the total Purchase Price, as the case may be, and such delivery of such Series 1
Exchangeable Share Consideration to the Transfer Agent shall be deemed to be
payment of and shall satisfy and discharge all liability for the total
Retraction Price or total Purchase Price, as the case may be, unless any cheque
included therein is not paid on due presentation.
 
6.5 On and after the close of business on the Retraction Date, the holder of the
Retracted Shares shall cease to be a holder of such Retracted Shares and shall
not be entitled to exercise any of the rights of a holder in respect thereof,
other than the right to receive his proportionate part of the total Retraction
Price or total Purchase Price, as the case may be, unless upon presentation and
surrender of certificates in accordance with the foregoing provisions, payment
of the total Retraction Price or the total Purchase Price, as the case may be,
shall not be made, in which case the rights of such holder shall remain
unaffected until the total Retraction Price or the total Purchase Price, as the
case may be, has been paid in the manner hereinbefore provided. On and after the
close of business on the Retraction Date, provided that presentation and
surrender of certificates and payment of the total Retraction Price or the total
Purchase Price, as the case may be, has been made in accordance with the
foregoing provisions, the holder of the Retracted Shares so redeemed by the
Corporation or purchased by Veritas shall thereafter be considered and deemed
for all purposes to be a holder of the Veritas Common Stock delivered to it.
Notwithstanding the foregoing, until such Series 1 Exchangeable Share
Consideration is delivered to the holder, the holder shall be deemed to still be
a holder of Series 1 Exchangeable Shares for purposes of all voting rights with
respect thereto under the Voting and Exchange Trust Agreement.
 
6.6 Notwithstanding any other provision of this Article 6, the Corporation shall
not be obligated to redeem Retracted Shares specified by a holder in a
Retraction Request to the extent that such redemption of Retracted Shares would
be contrary to liquidity or solvency requirements or other provisions of
applicable law. If the Corporation believes that on any Retraction Date it would
not be permitted by any of such provisions to redeem the Retracted Shares
tendered for redemption on such date, and provided that Veritas shall not have
exercised the Retraction Call Right with respect to the Retracted Shares, the
Corporation shall only be obligated to redeem Retracted Shares specified by a
holder in a Retraction Request to the extent of the maximum number that may be
so redeemed (rounded down to a whole number of shares) as would not be contrary
to such provisions and shall
 
                                      D-17
<PAGE>   241
 
notify the holder at least two Business Days prior to the Retraction Date as to
the number of Retracted Shares which will not be redeemed by the Corporation. In
any case in which the redemption by the Corporation of Retracted Shares or the
redemption by the Corporation of any other Class A Exchangeable Shares or
Exchangeable Shares would be contrary to liquidity or solvency requirements or
other provisions of applicable law, the Corporation shall redeem Retracted
Shares, the Exchangeable Shares and Class A Exchangeable Shares on a PRO RATA
basis and shall issue to each holder of Retracted Shares a new certificate, at
the expense of the Corporation, representing the Retracted Shares not redeemed
by the Corporation. Provided that the Retraction Request is not revoked by the
holder in the manner specified in Section 6.7, the holder of any such Retracted
Shares not redeemed by the Corporation pursuant to Section 6.2 of these share
provisions as a result of liquidity or solvency requirements of applicable law
shall be deemed by giving the Retraction Request to require Veritas to purchase
such Retracted Shares from such holder on the Retraction Date or as soon as
practicable thereafter on payment by Veritas to such holder of the Purchase
Price for each such Retracted Share, all as more specifically provided in the
Voting and Exchange Trust Agreement, and Veritas shall make such purchase.
 
6.7 A holder of Retracted Shares may, by notice in writing given by the holder
to the Corporation before the close of business on the Business Day immediately
preceding the Retraction Date, withdraw its Retraction Request in which event
such Retraction Request shall be null and void and, for greater certainty, the
revocable offer constituted by the Retraction Request to sell the Retracted
Shares to Veritas shall be deemed to have been revoked.
 
                                   ARTICLE 7
         REDEMPTION OF SERIES 1 EXCHANGEABLE SHARES BY THE CORPORATION
 
7.1 Subject to applicable law, and if Veritas does not exercise the Redemption
Call Right, the Corporation shall on the Automatic Redemption Date redeem the
whole of the then outstanding Series 1 Exchangeable Shares for an amount equal
to the Series 1 Exchangeable Share Price applicable on the last Business Day
prior to the Automatic Redemption Date (the "Redemption Price "). In connection
with payment of the Redemption Price, the Corporation shall be entitled to
liquidate some of the Veritas Common Stock that would otherwise be deliverable
to the particular holder of Series 1 Exchangeable Shares in order to fund any
statutory withholding tax obligation.
 
7.2 In any case of a redemption of Series 1 Exchangeable Shares under this
Article 7, the Corporation shall, at least 120 days before the Automatic
Redemption Date, send or cause to be sent to each holder of Series 1
Exchangeable Shares a notice in writing of the redemption by the Corporation or
the purchase by Veritas under the Redemption Call Right, as the case may be, of
the Series 1 Exchangeable Shares held by such holder. Such notice shall set out
the formula for determining the Redemption Price or the Redemption Call Purchase
Price, as the case may be, the Automatic Redemption Date and, if applicable,
particulars of the Redemption Call Right.
 
7.3 On or after the Automatic Redemption Date and subject to the exercise by
Veritas of the Redemption Call Right, the Corporation shall cause to be
delivered to the holders of the Series 1 Exchangeable Shares to be redeemed the
Redemption Price for each such Series 1 Exchangeable Share upon presentation and
surrender at the registered office of the Corporation or at any office of the
Transfer Agent as may be specified by the Corporation in such notice of the
certificates representing such Series 1 Exchangeable Shares, together with such
other documents and instruments as may be required to effect a transfer of
Series 1 Exchangeable Shares under the Business Corporations Act (Alberta) and
the by-laws of the Corporation and such additional documents and instruments as
the Transfer Agent may reasonably require. Payment of the total Redemption Price
for such Series 1 Exchangeable Shares shall be made by delivery to each holder,
at the address of the holder recorded in the securities register of the
Corporation or by holding for pick up by the holder at the registered office of
the Corporation or at any office of the Transfer Agent as may be specified by
the Corporation in such notice, on behalf of the Corporation of the Series 1
Exchangeable Share Consideration representing the total Redemption Price. On and
after the Automatic Redemption Date, the holders of the Series 1 Exchangeable
Shares called for redemption shall cease to be holders of such Series 1
Exchangeable Shares and shall not be entitled to exercise any of the rights of
holders in respect thereof, other than the right to receive their proportionate
part of the total Redemption Price, unless payment of the total Redemption Price
for such Series 1 Exchangeable Shares shall not
 
                                      D-18
<PAGE>   242
 
be made upon presentation and surrender of certificates in accordance with the
foregoing provisions, in which case the rights of the holders shall remain
unaffected until the total Redemption Price has been paid in the manner
hereinbefore provided. The Corporation shall have the right at any time after
the sending of notice of its intention to redeem the Series 1 Exchangeable
Shares as aforesaid to deposit or cause to be deposited the Series 1
Exchangeable Share Consideration with respect to the Series 1 Exchangeable
Shares so called for redemption, or of such of the said Series 1 Exchangeable
Shares represented by certificates that have not at the date of such deposit
been surrendered by the holders thereof in connection with such redemption, in a
custodial account or for safe keeping, in the case of non-cash items, with any
chartered bank or trust company in Canada named in such notice. Upon the later
of such deposit being made and the Automatic Redemption Date, the Series 1
Exchangeable Shares in respect whereof such deposit shall have been made shall
be redeemed and the rights of the holders thereof after such deposit or
Automatic Redemption Date, as the case may be, shall be limited to receiving
their proportionate part of the total Redemption Price for such Series 1
Exchangeable Shares so deposited, against presentation and surrender of the said
certificates held by them, respectively, in accordance with the foregoing
provisions. Upon such payment or deposit of such Series 1 Exchangeable Share
Consideration, the holders of the Series 1 Exchangeable Shares shall thereafter
be considered and deemed for all purposes to be holders of the Veritas Common
Stock delivered to them. Notwithstanding the foregoing, until such Series 1
Exchangeable Share Consideration is delivered to the holder, the holder shall be
deemed to still be a holder of Series 1 Exchangeable Shares for purposes of all
voting rights with respect thereto under the Voting and Exchange Trust
Agreement.
 
                                   ARTICLE 8

8.1 Except as required by applicable law and the provisions hereof, the holders
of the Series 1 Exchangeable Shares shall not be entitled as such to receive
notice of or to attend any meeting of the shareholders of the Corporation or to

1 Exchangeable Shares may be added to, changed or removed but, except as
hereinafter provided, only with the approval of the holders of the Series 1
Exchangeable Shares given as hereinafter specified.
 
9.2 Any approval given by the holders of the Series 1 Exchangeable Shares to add
to, change or remove any right, privilege, restriction or condition attaching to
the Series 1 Exchangeable Shares or any other matter requiring the approval or
consent of the holders of the Series 1 Exchangeable Shares shall be deemed to
have been sufficiently given if it shall have been given in accordance with
applicable law subject to a minimum requirement that such approval be evidenced
by resolution passed by not less than two-thirds of the votes cast on such
resolution by persons represented in person or by proxy at a meeting of holders
of Series 1 Exchangeable Shares duly called and held at which the holders of at
least 50% of the outstanding Series 1 Exchangeable Shares at that time are
present or represented by proxy (excluding Series 1 Exchangeable Shares
beneficially owned by Veritas or its Subsidiaries). If at any such meeting the
holders of at least 50% of the outstanding Series 1 Exchangeable Shares at that
time are not present or represented by proxy within one-half hour after the time
appointed for such meeting then the meeting shall be adjourned to such date not
less than 10 days thereafter and to such time and place as may be designated by
the Chairman of such meeting. At such adjourned meeting the holders of Series 1
Exchangeable Shares present or represented by proxy thereat may transact the
business for which the meeting was originally called and a resolution passed
thereat by the affirmative vote of not less than two-thirds of the votes cast on
such resolution by persons represented in person or by proxy at such meeting
shall constitute the approval or consent of the holders of the Series 1
Exchangeable Shares.

        (i)    issue or distribute Veritas Common Stock (or securities
               exchangeable for or convertible into or carrying rights to
               acquire Veritas Common Stock) to the holders of all or

        (ii)   issue or distribute rights, options or warrants to the holders of
               all or substantially all of the then outstanding Veritas Common
               Stock entitling them to subscribe for or to purchase shares of
               Veritas Common Stock (or securities exchangeable for or
               convertible into or carrying rights to acquire shares of Veritas
               Common Stock); or
 
        (iii)  issue or distribute to the holders of all or substantially all of
               the then outstanding shares of Veritas Common Stock (A) shares or
               securities of Veritas of any class other than Veritas Common
               Stock (other than shares convertible into or exchangeable for or
               carrying rights to acquire Veritas Common Stock), (B) rights,
               options or warrants other than those referred to in Section
               10.1(a)(ii) above, (C) evidences of indebtedness of Veritas or

unless the Corporation is permitted under applicable law to issue or distribute
the equivalent on a per share basis of such rights, options, securities, shares,
evidences of indebtedness or other assets to holders of the Series 1
Exchangeable Shares and the Corporation shall issue or distribute such rights,
options, securities, shares, evidences of indebtedness or other assets
simultaneously to holders of the Series 1 Exchangeable Shares.
 
     (b)   Each holder of a Series 1 Exchangeable Share acknowledges that the
Support Agreement further provides, in part, that Veritas will not without the
prior approval of the Corporation and the prior approval of the holders of the
Series 1 Exchangeable Shares given in accordance with Section 9.2 of these share
provisions:
 
        (i)    subdivide, redivide or change the then outstanding shares of
               Veritas Common Stock into a greater number of shares of Veritas
               Common Stock; or
 
        (ii)   reduce, combine or consolidate or change the then outstanding
               shares of Veritas Common Stock into a lesser number of shares of
               Veritas Common Stock; or

               or effect an amalgamation, merger, reorganization or other
               transaction affecting the shares of Veritas Common Stock;
 
unless the Corporation is permitted under applicable law to simultaneously make
the same or an equivalent change to, or in the rights of holders of, the Series
1 Exchangeable Shares and the same or an equivalent change is made to, or in the
rights of the holders of, the Series 1 Exchangeable Shares.
 
     The Support Agreement further provides, in part, that the aforesaid
provisions of the Support Agreement shall not be changed without the approval of
the holders of the Series 1 Exchangeable Shares given in accordance with Section
9.2 of these share provisions.

           as any Series 1 Exchangeable Shares are outstanding, Veritas will:
 
           (i)    not declare or pay any dividend on Veritas Common Stock unless
                  (A) VESI will have sufficient assets, funds and other property
                  available to enable the due declaration and the due and
                  punctual payment in accordance with applicable law of an

           (ii)   cause VESI to declare simultaneously with the declaration of
                  any dividend on Veritas Common Stock an equivalent dividend on
                  the Series 1 Exchangeable Shares and, when such dividend is
                  paid on Veritas Common Stock, cause VESI to pay simultaneously
                  therewith such equivalent dividend on the Series 1
                  Exchangeable Shares, in each case in accordance with the
                  Exchangeable Share Provisions;
 
           (iii)  advise VESI sufficiently in advance of the declaration by
                  Veritas of any dividend on Veritas Common Stock and take all
                  such other actions as are necessary, in cooperation with VESI,
                  to ensure that the respective declaration date, record date
                  and payment date for a dividend on the Series 1 Exchangeable
                  Shares shall be the same as the record date, declaration date
                  and payment date for the corresponding dividend on Veritas
                  Common Stock and such dividend on the Series 1 Exchangeable

                  stock exchange on which the Series 1 Exchangeable Shares are
                  listed;
 
           (iv)   ensure that the record date for any dividend declared on
                  Veritas Common Stock is not less than 10 Business Days after
                  the declaration date for such dividend;
 
           (v)    take all such actions and do all such things as are necessary
                  or desirable to enable and permit VESI, in accordance with
                  applicable law, to pay and otherwise perform its obligations
                  with respect to the satisfaction of the Liquidation Amount in
                  respect of each issued and outstanding Series 1 Exchangeable
                  Share upon the liquidation, dissolution or winding-up of VESI,
                  including without limitation all such actions and all such
                  things as are necessary or desirable to enable and permit VESI
                  to cause to be delivered shares of Veritas Common Stock to the
                  holders of Series 1 Exchangeable Shares in accordance with the
                  provisions of Article 5 of the Exchangeable Share Provisions;
 
           (vi)   take all such actions and do all such things as are necessary
                  or desirable to enable and permit VESI, in accordance with
                  applicable law, to pay and otherwise perform its obligations
                  with respect to the satisfaction of the Retraction Price and
                  the Redemption Price, including without limitation all such
                  actions and all such things as are necessary or desirable to

                  Veritas Common Stock to the holders of Series 1 Exchangeable
                  Shares, upon the retraction or redemption of the Series 1
                  Exchangeable Shares in accordance with the provisions of
                  Article 6 or Article 7 of the Exchangeable Share Provisions,
                  as the case may be; and
 
           (vii)  not exercise its vote as a shareholder to initiate the
                  voluntary liquidation, dissolution or winding-up of VESI, nor
                  take any action or omit to take any action that is designed to
                  result in, nor omit to take any action to prevent, the

           hereunder, including for greater certainty, pursuant to the

           provincial or state law or regulation or pursuant to the rules and
           regulations of any regulatory authority or the fulfillment of any
           other legal requirement (collectively, the "Applicable Laws ") before
           such shares (or other shares or securities into which Veritas Common
           Stock may be reclassified or changed as contemplated by Section 2(g)
           hereof) may be issued and delivered by Veritas to the initial holder
           thereof (other than VESI) or in order that such shares may be freely
           traded thereafter (other than any restrictions on transfer by reason

           Veritas or, prior to the Effective Date, of Enertec for purposes of
           United States federal or state securities law), Veritas will in good
           faith expeditiously take all such actions and do all such things as

           representing Series 1 Exchangeable Shares to bear an appropriate

           right to consent to or to vote in person or by proxy the Voting
           Share, on any matter, question or proposition whatsoever that may
           properly come before the stockholders of Veritas at a Veritas Meeting
           or in connection with a Veritas Consent (in each case, as hereinafter
           defined). The Voting Rights shall be and remain vested in and
           exercised by the Trustee. Subject to Section 7(o) hereof, the Trustee
           shall exercise the Voting Rights only on the basis of instructions
           received pursuant to this Article 4 from Holders entitled to instruct
           the Trustee as to the voting thereof at the time at which a Veritas
           Consent is sought or a Veritas Meeting is held. To the extent that no
           instructions are received from a Holder with respect to the Voting
           Rights to which such Holder is entitled, the Trustee shall not
           exercise or permit the exercise of such Holder's Voting Rights.

        shall be determined at the close of business on the record date
        established by Veritas or by applicable law for purposes of determining
        stockholders entitled to vote at such Veritas Meeting or to give written
        consent in connection with such Veritas Consent. Veritas will notify the

        shall be deemed to be surrendered by the Holder to Veritas and such
        Holder Votes and the Voting Rights represented thereby shall cease
        immediately upon the delivery by such Holder to the Trustee of the
        certificates representing such Series 1 Exchangeable Shares in
        connection with the exercise by the Holder of the Exchange Right or the
        occurrence of the automatic exchange of Series 1 Exchangeable Shares for
        shares of Veritas Common Stock, as specified in Article 5 hereof (unless
        in either case Veritas shall not have delivered the Series 1
        Exchangeable Share Consideration deliverable in exchange therefor to the
        Trustee for delivery to the Holders), or upon the redemption of Series 1
        Exchangeable Shares pursuant to Article 6 or Article 7 of the
        Exchangeable Share Provisions, or upon the effective date of the
        liquidation, dissolution or winding-up of VESI pursuant to Article 5 of
        the Exchangeable Share Provisions, or upon the purchase of Series 1
        Exchangeable Shares from the holder thereof by Veritas pursuant to the
        exercise by Veritas of the Retraction Call Right, the Redemption Call
        Right or the Liquidation Call Right.
 
5. EXCHANGE RIGHT AND AUTOMATIC EXCHANGE
 
   (a)  GRANT AND OWNERSHIP OF THE EXCHANGE RIGHT.  Veritas hereby grants to the
        Trustee as trustee for and on behalf of, and for the use and benefit of,
        the Holders (i) the right (the "Exchange Right"), upon the occurrence
        and during the continuance of an Insolvency Event, to require Veritas to
        purchase from each or any Holder all or any part of the Series 1
        Exchangeable Shares held by the Holders, and (ii) the Automatic Exchange
        Rights, all in accordance with the provisions of this agreement. Veritas
        hereby acknowledges receipt from the Trustee as trustee for and on
        behalf of the Holders of good and valuable consideration (and the
        adequacy thereof) for the grant of the Exchange Right and the Automatic
        Exchange Rights by Veritas to the Trustee. During the term of the Trust
        and subject to the terms and conditions of this agreement, the Trustee
        shall possess and be vested with full legal ownership of the Exchange
        Right and the Automatic Exchange Rights and shall be entitled to
        exercise all of the rights and powers of an owner with respect to the
        Exchange Right and the Automatic Exchange Rights, provided that the
        Trustee shall:
 
                                       F-7
<PAGE>   265
           (iii) hold the Exchange Right and the Automatic Exchange Rights and
                 the legal title thereto as trustee solely for the use and
                 benefit of the Holders in accordance with the provisions of
                 this agreement; and
 
           (iv)  except as specifically authorized by this agreement, have no
                 power or authority to exercise or otherwise deal in or with the
                 Exchange Right or the Automatic Exchange Rights, and the
                 Trustee shall not exercise any such rights for any purpose
                 other than the purposes for which this Trust is created
                 pursuant to this agreement.
 
     (b)   LEGENDED SHARE CERTIFICATES.  VESI will cause each certificate
           representing Series 1 Exchangeable Shares to bear an appropriate
           legend notifying the Holders of:
 
           (i)   their right to instruct the Trustee with respect to the
                 exercise of the Exchange Right in respect of the Series 1
                 Exchangeable Shares held by a Holder; and
 
           (ii)  the Automatic Exchange Rights.
 
     (c)   GENERAL EXERCISE OF EXCHANGE RIGHT.  The Exchange Right shall be and
           remain vested in and exercised by the Trustee. Subject to Section
           7(o) hereof, the Trustee shall exercise the Exchange Right only on
           the basis of instructions received pursuant to this Article 5 from
           Holders entitled to instruct the Trustee as to the exercise thereof.
           To the extent that no instructions are received from a Holder with
           respect to the Exchange Right, the Trustee shall not exercise or
           permit the exercise of the Exchange Right.
 
     (d)   PURCHASE PRICE.  The purchase price payable by Veritas for each
           Series 1 Exchangeable Share to be purchased by Veritas under the
           Exchange Right shall be an amount equal to the Series 1 Exchangeable
           Share Price on the last Business Day prior to the day of closing of
           the purchase and sale of such Series 1 Exchangeable Share under the
           Exchange Right. In connection with each exercise of the Exchange
           Right, Veritas will provide to the Trustee an Officer's Certificate
           setting forth the calculation of the Series 1 Exchangeable Share
           Price for each Series 1 Exchangeable Share. The Series 1 Exchangeable
           Share Price for each such Series 1 Exchangeable Share so purchased
           may be satisfied only by Veritas issuing and delivering or causing to
           be delivered to the Trustee, on behalf of the relevant Holder, the
           Series 1 Exchangeable Share Consideration representing the total
           Series 1 Exchangeable Share Price.
 
     (e)   EXERCISE INSTRUCTIONS.  Subject to the terms and conditions herein
           set forth, a Holder shall be entitled, upon the occurrence and during
           the continuance of an Insolvency Event, to instruct the Trustee to
           exercise the Exchange Right with respect to all or any part of the
           Series 1 Exchangeable Shares registered in the name of such Holder on
           the books of VESI. To cause the exercise of the Exchange Right by the
           Trustee, the Holder shall deliver to the Trustee, in person or by
           certified or registered mail, at its principal office in Calgary,
           Alberta, Toronto, Ontario or at such other places in Canada as the
           Trustee may from time to time designate by written notice to the
           Holders, the certificates representing the Series 1 Exchangeable
           Shares which such Holder desires Veritas to purchase, duly endorsed
           in blank, and accompanied by such other documents and instruments as
           may be required to effect a transfer of Series 1 Exchangeable Shares
           under the Business Corporations Act (Alberta), other applicable laws,
           if any, and the by-laws of VESI and such additional documents and
           instruments as the Trustee may reasonably require together with (i) a
           duly completed form of notice of exercise of the Exchange Right,
           contained on the reverse of or attached to the Series 1 Exchangeable
           Share certificates, stating (A) that the Holder thereby instructs the
           Trustee to exercise the Exchange Right so as to require Veritas to
           purchase from the Holder the number of Series 1 Exchangeable Shares
           specified therein, (B) that such Holder has good title to and owns
           all such Series 1 Exchangeable Shares to be acquired by Veritas free
           and clear of all liens, claims and encumbrances, (C) the names in
           which the certificates representing Veritas Common Stock issuable in
           connection with the exercise of the Exchange Right are to be issued
           and (D) the names and addresses of the persons to whom the Series 1
           Exchangeable Share Consideration should be delivered and (ii) payment
           (or evidence satisfactory to the Trustee, VESI and Veritas of
           payment) of the taxes (if any) payable as
 
                                       F-8
<PAGE>   266
 
        contemplated by Section 5(h) of this agreement. If only a part of the
        Series 1 Exchangeable Shares represented by any certificate or
        certificates delivered to the Trustee are to be purchased by Veritas
        under the Exchange Right, a new certificate for the balance of such
        Series 1 Exchangeable Shares shall be issued to the Holder at the
        expense of VESI.
 
     (f)   DELIVERY OF SERIES 1 EXCHANGEABLE SHARE CONSIDERATION; EFFECT OF
           EXERCISE. Promptly after receipt of the certificates representing the
           Series 1 Exchangeable Shares which the Holder desires Veritas to
           purchase under the Exchange Right (together with such documents and
           instruments of transfer and a duly completed form of notice of
           exercise of the Exchange Right), duly endorsed for transfer to
           Veritas, the Trustee shall notify Veritas and VESI of its receipt of
           the same, which notice to Veritas and VESI shall constitute exercise
           of the Exchange Right by the Trustee on behalf of the Holder of such
           Series 1 Exchangeable Shares, and Veritas shall immediately
           thereafter deliver or cause to be delivered to the Trustee, for
           delivery to the Holder of such Series 1 Exchangeable Shares (or to
           such other persons, if any, properly designated by such Holder), the
           Series 1 Exchangeable Share Consideration deliverable in connection
           with the exercise of the Exchange Right; provided, however, that no
           such delivery shall be made unless and until the Holder requesting
           the same shall have paid (or provided evidence satisfactory to the
           Trustee, VESI and Veritas of the payment of) the taxes (if any)
           payable as contemplated by Section 5(h) of this agreement. In
           connection with payment of the Series 1 Exchangeable Share
           Consideration, Veritas shall be entitled to liquidate some of the
           Veritas Common Stock that would otherwise be deliverable to the
           particular holder of Series 1 Exchangeable Shares in order to fund
           any statutory withholding tax obligation. Immediately upon the giving
           of notice by the Trustee to Veritas and VESI of the exercise of the
           Exchange Right, as provided in this Section 5(f), the closing of the
           transaction of purchase and sale contemplated by the Exchange Right
           shall be deemed to have occurred, and the Holder of such Series 1
           Exchangeable Shares shall be deemed to have transferred to Veritas
           all of its right, title and interest in and to such Series 1
           Exchangeable Shares and in the related interest in the Trust Estate
           and shall cease to be a holder of such Series 1 Exchangeable Shares
           and shall not be entitled to exercise any of the rights of a holder
           in respect thereof, other than the right to receive his proportionate
           part of the total purchase price therefor, unless such Series 1
           Exchangeable Share Consideration is not delivered by Veritas to the
           Trustee, for delivery to such Holder (or to such other persons, if
           any, properly designated by such Holder), within five Business Days
           of the date of the giving of such notice by the Trustee, in which
           case the rights of the Holder shall remain unaffected until such
           Series 1 Exchangeable Share Consideration is delivered by Veritas and
           any cheque included therein is paid. Concurrently with such Holder
           ceasing to be a holder of Series 1 Exchangeable Shares, the Holder
           shall be considered and deemed for all purposes to be the holder of
           the shares of Veritas Common Stock delivered to it pursuant to the
           Exchange Right. Notwithstanding the foregoing until the Series 1
           Exchangeable Share Consideration is delivered to the Holder, the
           Holder shall be deemed to still be a holder of the sold Series 1
           Exchangeable Shares for purposes of voting rights with respect
           thereto under this agreement.
 
     (g)   EXERCISE OF EXCHANGE RIGHT SUBSEQUENT TO RETRACTION.  In the event
           that a Holder has exercised its right under Article 6 of the
           Exchangeable Share Provisions to require VESI to redeem any or all of
           the Series 1 Exchangeable Shares held by the Holder (the "Retracted
           Shares") and is notified by VESI pursuant to Section 6.6 of the
           Exchangeable Share Provisions that VESI will not be permitted as a
           result of liquidity or solvency requirements of applicable law to
           redeem all such Retracted Shares, subject to receipt by the Trustee
           of written notice to that effect from VESI and provided that Veritas
           shall not have exercised the Retraction Call Right with respect to
           the Retracted Shares and that the Holder has not revoked the
           retraction request delivered by the Holder to VESI pursuant to
           Section 6.1 of the Exchangeable Share Provisions, the retraction
           request will constitute and will be deemed to constitute notice from
           the Holder to the Trustee instructing the Trustee to exercise the
           Exchange Right with respect to those Retracted Shares which VESI is
           unable to redeem. In any such event, VESI hereby agrees with the
           Trustee and in favour of the Holder immediately to notify the Trustee
           of such prohibition against VESI redeeming all of the Retracted
           Shares and immediately to forward or cause to be forwarded to the
           Trustee all relevant materials delivered by the
                                       F-9
<PAGE>   267
           Holder to VESI or to the transfer agent of the Series 1 Exchangeable
           Shares (including without limitation a copy of the retraction request
           delivered pursuant to Section 6.1 of the Exchangeable Share
           Provisions) in connection with such proposed redemption of the
           Retracted Shares and the Trustee will thereupon exercise the Exchange
           Right with respect to the Retracted Shares that VESI is not permitted
           to redeem and will require Veritas to purchase such shares in
           accordance with the provisions of this Article 5.
 
     (h)   STAMP OR OTHER TRANSFER TAXES.  Upon any sale of Series 1
           Exchangeable Shares to Veritas pursuant to the Exchange Right or the
           Automatic Exchange Rights, the share certificate or certificates
           representing Veritas Common Stock to be delivered in connection with
           the payment of the total purchase price therefor shall be issued in
           the name of the Holder of the Series 1 Exchangeable Shares so sold or
           in such names as such Holder may otherwise direct in writing without
           charge to the holder of the Series 1 Exchangeable Shares so sold,
           provided, however, that such Holder (i) shall pay (and neither
           Veritas, VESI nor the Trustee shall be required to pay) any
           documentary, stamp, transfer or other similar taxes that may be
           payable in respect of any transfer involved in the issuance or
           delivery of such shares to a person other than such Holder or (ii)
           shall have established to the satisfaction of the Trustee, Veritas
           and VESI that such taxes, if any, have been paid.
 
     (i)   NOTICE OF INSOLVENCY EVENT.  Immediately upon the occurrence of an
           Insolvency Event or any event which with the giving of notice or the
           passage of time or both would be an Insolvency Event, VESI and
           Veritas shall give written notice thereof to the Trustee. As soon as
           practicable after receiving notice from VESI and Veritas or from any
           other Person of the occurrence of an Insolvency Event, the Trustee
           will mail to each Holder, at the expense of Veritas, a notice of such
           Insolvency Event in the form provided by Veritas, which notice shall
           contain a brief statement of the right of the Holders with respect to
           the Exchange Right.
 
     (j)   QUALIFICATION OF VERITAS COMMON STOCK.  Veritas covenants that if any
           shares of Veritas Common Stock to be issued and delivered pursuant to
           the Exchange Right or the Automatic Exchange Rights require
           registration or qualification with or approval of or the filing of
           any document including any prospectus or similar document or the
           taking of any proceeding with or the obtaining of any order, ruling
           or consent from any governmental or regulatory authority under any
           Canadian or United States federal, provincial or state law or
           regulation or pursuant to the rules and regulations of any regulatory
           authority or the fulfillment of any other legal requirement
           (collectively, the "Applicable Laws") before such shares may be
           issued and delivered by Veritas to the initial holder thereof (other
           than VESI) or in order that such shares may be freely traded
           thereafter (other than any restrictions on transfer by reason of a
           holder being a "control person" of Veritas for purposes of Canadian
           federal or provincial securities law or an "affiliate" of Veritas or,
           prior to the Effective Date, of Enertec for purposes of United States
           federal or state securities law), Veritas will in good faith
           expeditiously take all such actions and do all such things as are
           necessary to cause such shares of Veritas Common Stock to be and
           remain duly registered, qualified or approved. Veritas represents and
           warrants that it has in good faith taken all actions and done all
           things as are necessary under Applicable Laws as they exist on the
           date hereof to cause the shares of Veritas Common Stock to be issued
           and delivered pursuant to the Exchange Right and the Automatic
           Exchange Rights and to be freely tradeable thereafter (other than
           restrictions on transfer by reason of a holder being a "control
           person" of Veritas for the purposes of Canadian federal and
           provincial securities law or an "affiliate" of Veritas or, prior to
           the Effective Date, of Enertec for the purposes of United States
           federal or state securities law). Veritas will in good faith
           expeditiously take all such actions and do all such things as are
           necessary to cause all shares of Veritas Common Stock to be delivered
           pursuant to the Exchange Right or the Automatic Exchange Rights to be
           and to continue to be listed, quoted or posted for trading on all
           stock exchanges and quotation systems on which such shares are
           listed, quoted or posted for trading at such time.
 
     (k)   RESERVATION OF SHARES OF VERITAS COMMON STOCK.
 
           Veritas hereby represents, warrants and covenants that it has
           irrevocably reserved for issuance and will at all times keep
           available, free from pre-emptive and other rights, out of its
           authorized and unissued
 
                                      F-10
<PAGE>   268
           capital stock such number of shares of Veritas Common Stock (i) as is
           equal to the sum of (A) the number of Series 1 Exchangeable Shares
           issued and outstanding from time to time and (B) the number of Series
           1 Exchangeable Shares issuable upon the exercise of all rights to
           acquire Series 1 Exchangeable Shares outstanding from time to time
           and (ii) as are now and may hereafter be required to enable and
           permit Veritas and VESI to meet their respective obligations
           hereunder, under the Restated Certificate of Incorporation of
           Veritas, under the Support Agreement, under the Exchangeable Share
           Provisions and under any other security or commitment pursuant to the
           Arrangement with respect to which Veritas may now or hereafter be
           required to issue shares of Veritas Common Stock.
 
     (l)   AUTOMATIC EXCHANGE ON LIQUIDATION OF VERITAS.
 
           (i)   Veritas will give the Trustee written notice of each of the
                 following events at the time set forth below:
 
                 (A)  in the event of any determination by the board of
                      directors of the Veritas to institute voluntary
                      liquidation, dissolution or winding-up proceedings with
                      respect to Veritas or to effect any other distribution of
                      assets of Veritas among its stockholders for the purpose
                      of winding-up its affairs, at least 60 days prior to the
                      proposed effective date of such liquidation, dissolution,
                      winding-up or other distribution; and
 
                 (B)  immediately, upon the earlier of (I) receipt by Veritas of
                      notice of, and (II) Veritas otherwise becoming aware of,
                      any threatened or instituted claim, suit, petition or
                      other proceedings with respect to the involuntary
                      liquidation, dissolution or winding-up of Veritas or to
                      effect any other distribution of assets of Veritas among
                      its stockholders for the purpose of winding-up its
                      affairs.
 
           (ii)  Immediately following receipt by the Trustee from Veritas of
                 notice of any event (a "Liquidation Event ") contemplated by
                 Section 5(l)(i) above, the Trustee will give notice thereof to
                 the Holders. Such notice will be provided by Veritas to the
                 Trustee and shall include a brief description of the automatic
                 exchange of Series 1 Exchangeable Shares for shares of Veritas
                 Common Stock provided for in Section 5(l)(iii) below.
 
           (iii) In order that the Holders will be able to participate on a PRO
                 RATA basis with the holders of Veritas Common Stock in the
                 distribution of assets of Veritas in connection with a
                 Liquidation Event, immediately prior to the effective time (the
                 "Liquidation Event Effective Time") of a Liquidation Event all
                 of the then outstanding Series 1 Exchangeable Shares shall be
                 automatically exchanged for shares of Veritas Common Stock. To
                 effect such automatic exchange, Veritas shall be deemed to have
                 purchased each Series 1 Exchangeable Share outstanding
                 immediately prior to the Liquidation Event Effective Time and
                 held by Holders, and each Holder shall be deemed to have sold
                 the Series 1 Exchangeable Shares held by it at such time, for a
                 purchase price per share equal to the Series 1 Exchangeable
                 Share Price applicable at such time. In connection with such
                 automatic exchange, Veritas will provide to the Trustee an
                 Officer's Certificate setting forth the calculation of the
                 purchase price for each Series 1 Exchangeable Share.
 
           (iv)  The closing of the transaction of purchase and sale
                 contemplated by Section 5(l)(iii) above shall be deemed to have
                 occurred immediately prior to the Liquidation Event Effective
                 Time, and each Holder of Series 1 Exchangeable Shares shall be
                 deemed to have transferred to Veritas all of the Holder's
                 right, title and interest in and to such Series 1 Exchangeable
                 Shares and the related interest in the Trust Estate and shall
                 cease to be a holder of such Series 1 Exchangeable Shares and
                 Veritas shall deliver to the Holder the Series 1 Exchangeable
                 Share Consideration deliverable upon the automatic exchange of
                 Series 1 Exchangeable Shares. In connection with payment of the
                 Series 1 Exchangeable Share Consideration, Veritas shall be
                 entitled to liquidate some of the Veritas Common Stock that
                 would otherwise be deliverable to the particular holder of
                 Series 1 Exchangeable Shares in order to fund any statutory
                 withholding tax obligation. Concurrently with such Holder
                 ceasing to be a holder of Series 1 Exchangeable Shares, the
 
                                      F-11
<PAGE>   269
              Holder shall be considered and deemed for all purposes to be the
              holder of the shares of Veritas Common Stock issued to it pursuant
              to the automatic exchange of Series 1 Exchangeable Shares for
              Veritas Common Stock and the certificates held by the Holder
              previously representing the Series 1 Exchangeable Shares exchanged
              by the Holder with Veritas pursuant to such automatic exchange
              shall thereafter be deemed to represent the shares of Veritas
              Common Stock issued to the Holder by Veritas pursuant to such
              automatic exchange. Upon the request of a Holder and the surrender
              by the Holder of Series 1 Exchangeable Share certificates deemed
              to represent shares of Veritas Common Stock, duly endorsed in
              blank and accompanied by such instruments of transfer as Veritas
              may reasonably require, Veritas shall deliver or cause to be
              delivered to the Holder certificates representing the shares of
              Veritas Common Stock of which the Holder is the holder.
              Notwithstanding the foregoing until each Holder is actually
              entered on the register of holders of Veritas Common Stock, such
              Holder shall be deemed to still be a holder of the transferred
              Series 1 Exchangeable Shares for purposes of all voting rights
              with respect thereto under this agreement.
 
6.   RESTRICTIONS ON ISSUANCE OF VERITAS ERS SPECIAL VOTING STOCK
 
     During the term of this agreement, Veritas will not issue any shares of
Veritas ERS Special Voting Stock in addition to the Voting Share.
 
7.   CONCERNING THE TRUSTEE
 
     (a)   POWERS AND DUTIES OF THE TRUSTEE.  The rights, powers and authorities
           of the Trustee under this agreement, in its capacity as trustee of
           the Trust, shall include:
 
           (i)   receipt and deposit of the Voting Share from Veritas as trustee
                 for and on behalf of the Holders in accordance with the
                 provisions of this agreement;
 
           (ii)  granting proxies and distributing materials to Holders as
                 provided in this agreement;
 
           (iii) voting the Holder Votes in accordance with the provisions of
                 this agreement;
 
           (iv)  receiving the grant of the Exchange Right and the Automatic
                 Exchange Rights from Veritas as trustee for and on behalf of
                 the Holders in accordance with the provisions of this
                 agreement;
 
           (v)   exercising the Exchange Right and enforcing the benefit of the
                 Automatic Exchange Rights, in each case in accordance with the
                 provisions of this agreement, and in connection therewith
                 receiving from Holders Series 1 Exchangeable Shares and other
                 requisite documents and distributing to such Holders the shares
                 of Veritas Common Stock and cheques and property, if any, to
                 which such Holders are entitled upon the exercise of the
                 Exchange Right or pursuant to the Automatic Exchange Rights, as
                 the case may be;
 
           (vi)  holding title to the Trust Estate;
 
           (vii) investing any moneys forming, from time to time, a part of the
                 Trust Estate as provided in this agreement;
 
           (viii) taking action at the direction of a Holder or Holders to
                  enforce the obligations of Veritas under this agreement; and
 
           (ix)  taking such other actions and doing such other things as are
                 specifically provided in this agreement.
 
           In the exercise of such rights, powers and authorities the Trustee
           shall have (and is granted) such incidental and additional rights,
           powers and authority not in conflict with any of the provisions of
           this agreement as the Trustee, acting in good faith and in the
           reasonable exercise of its discretion, may deem necessary,
           appropriate or desirable to effect the purpose of the Trust. Any
           exercise of such discretionary rights, powers and authorities by the
           Trustee shall be final, conclusive and binding upon
 
                                      F-12
<PAGE>   270
         all persons. For greater certainty, the Trustee shall have only those
         duties as are set out specifically in this agreement.
 
         The Trustee in exercising its rights, powers, duties and authorities
         hereunder shall act honestly and in good faith with a view to the best
         interests of the Holders and shall exercise the care, diligence and
         skill that a reasonably prudent trustee would exercise in comparable
         circumstances.
 
         The Trustee shall not be bound to give any notice or do or take any
         act, action or proceeding by virtue of the powers conferred on it
         hereby unless and until it shall be specifically required to do so
         under the terms hereof; nor shall the Trustee be required to take any
         notice of, or to do or to take any act, action or proceeding as a
         result of any default or breach of any provision hereunder, unless and
         until notified in writing of such default or breach, which notices
         shall distinctly specify the default or breach desired to be brought to
         the attention of the Trustee and in the absence of such notice the
         Trustee may for all purposes of this agreement conclusively assume that
         no default or breach has been made in the observance or performance of
         any of the representations, warranties, covenants, agreements or
         conditions contained herein.
 
     (b) NO CONFLICT OF INTEREST.  The Trustee represents to VESI and Veritas
         that at the date of execution and delivery of this agreement there
         exists no material conflict of interest in the role of the Trustee as a
         fiduciary hereunder and the role of the Trustee in any other capacity.
         The Trustee shall, within 90 days after it becomes aware that such a
         material conflict of interest exists, either eliminate such material
         conflict of interest or resign in the manner and with the effect
         specified in Article 10 hereof. If, notwithstanding the foregoing
         provisions of this Section 7(b), the Trustee has such a material
         conflict of interest, the validity and enforceability of this agreement
         shall not be affected in any manner whatsoever by reason only of the
         existence of such material conflict of interest. If the Trustee
         contravenes the foregoing provisions of this Section 7(b), any
         interested party may apply to the Alberta Court of Queen's Bench an
         order that the Trustee be replaced as trustee hereunder.
 
     (c) DEALINGS WITH TRANSFER AGENTS, REGISTRARS, ETC.  VESI and Veritas
         irrevocably authorize the Trustee, from time to time, to:
 
         (i)  consult, communicate and otherwise deal with the respective
              registrars and transfer agents, and with any such subsequent
              registrar or transfer agent, of the Series 1 Exchangeable Shares
              and Veritas Common Stock; and
 
         (ii) requisition, from time to time, (A) from any such registrar or
              transfer agent any information readily available from the records
              maintained by it which the Trustee may reasonably require for the
              discharge of its duties and responsibilities under this agreement
              and (B) from the transfer agent of Veritas Common Stock, and any
              subsequent transfer agent of such shares, the share certificates
              issuable upon the exercise from time to time of the Exchange Right
              and pursuant to the Automatic Exchange Rights in the manner
              specified in Article 5 hereof.
 
         VESI and Veritas irrevocably authorize their respective registrars and
         transfer agents to comply with all such requests. Veritas covenants
         that it will supply its transfer agent with duly executed share
         certificates for the purpose of completing the exercise from time to
         time of the Exchange Right and the Automatic Exchange Rights, in each
         case pursuant to Article 5 hereof.
 
     (d) BOOKS AND RECORDS.  The Trustee shall keep available for inspection by
         Veritas and VESI, at the Trustee's principal office in Calgary,
         Alberta, correct and complete books and records of account relating to
         the Trustee's actions under this agreement, including without
         limitation all information relating to mailings and instructions to and
         from Holders and all transactions pursuant to the Voting Rights, the
         Exchange Right and the Automatic Exchange Rights for the term of this
         agreement. On or before June 30, 2000, and on or before June 30 in
         every year thereafter, so long as the Voting Share is on deposit with
         the Trustee, the Trustee shall transmit to Veritas and VESI a brief
         report, dated as of the preceding March 31, with respect to:
 
         (i)  the property and funds comprising the Trust Estate as of that
              date;
 
                                      F-13
<PAGE>   271
         (ii)  the number of exercises of the Exchange Right, if any, and the
               aggregate number of Series 1 Exchangeable Shares received by the
               Trustee on behalf of Holders in consideration of the issue and
               delivery by Veritas of shares of Veritas Common Stock in
               connection with the Exchange Right, during the calendar year
               ended on such date; and
 
         (iii) all other actions taken by the Trustee in the performance of its
               duties under this agreement which it had not previously reported.
 
     (e) INCOME TAX RETURNS AND REPORTS.  The Trustee shall, to the extent
         necessary, prepare and file on behalf of the Trust appropriate United
         States and Canadian income tax returns and any other returns or reports
         as may be required by applicable law or pursuant to the rules and
         regulations of any securities exchange or other trading system through
         which the Series 1 Exchangeable Shares are traded and, in connection
         therewith, may obtain the advice and assistance of such experts as the
         Trustee may consider necessary or advisable. If requested by the
         Trustee, Veritas shall retain such experts for purposes of providing
         such advice and assistance.
 
     (f) INDEMNIFICATION PRIOR TO CERTAIN ACTIONS BY TRUSTEE.  The Trustee
         shall exercise any or all of the rights, duties, powers or authorities
         vested in it by this agreement at the request, order or direction of
         any Holder upon such Holder furnishing to the Trustee reasonable
         funding, security and indemnity against the costs, expenses and
         liabilities which may be incurred by the Trustee therein or thereby,
         provided that no Holder shall be obligated to furnish to the Trustee
         any such funding, security or indemnity in connection with the exercise
         by the Trustee of any of its rights, duties, powers and authorities
         with respect to the Voting Share pursuant to Article 4 hereof, subject
         to Section 7(o) hereof, and with respect to the Exchange Right pursuant
         to Article 5 hereof, subject to Section 7(o) hereof, and with respect
         to the Automatic Exchange Rights pursuant to Article 5 hereof.
 
         None of the provisions contained in this agreement shall require the
         Trustee to expend or risk its own funds or otherwise incur financial
         liability in the exercise of any of its rights, powers, duties or
         authorities unless funded, given funds, security and indemnified as
         aforesaid.
 
     (g) ACTIONS BY HOLDERS. No Holder shall have the right to institute any
         action, suit or proceeding or to exercise any other remedy authorized
         by this agreement for the purpose of enforcing any of its rights or for
         the execution of any trust or power hereunder unless the Holder has
         requested the Trustee to take or institute such action, suit or
         proceeding and furnished the Trustee with the funding, security and
         indemnity referred to in Section 7(f) hereof and the Trustee shall have
         failed to act within a reasonable time thereafter. In such case, but
         not otherwise, the Holder shall be entitled to take proceedings in any
         court of competent jurisdiction such as the Trustee might have taken;
         it being understood and intended that no one or more Holders shall have
         any right in any manner whatsoever to affect, disturb or prejudice the
         rights hereby created by any such action, or to enforce any right
         hereunder or under the Voting Rights, the Exchange Right or the
         Automatic Exchange Rights, except subject to the conditions and in the
         manner herein provided, and that all powers and trusts hereunder shall
         be exercised and all proceedings at law shall be instituted, had and
         maintained by the Trustee, except only as herein provided, and in any
         event for the equal benefit of all Holders.
 
     (h) RELIANCE UPON DECLARATIONS.  The Trustee shall not be considered to be
         in contravention of any of its rights, powers, duties and authorities
         hereunder if, when required, it acts and relies in good faith upon
         lists, mailing labels, notices, statutory declarations, certificates,
         opinions, reports or other papers or documents furnished pursuant to
         the provisions hereof or required by the Trustee to be furnished to it
         in the exercise of its rights, powers, duties and authorities hereunder
         and such lists, mailing labels, notices, statutory declarations,
         certificates, opinions, reports or other papers or documents comply
         with the provisions of Section 7(i) hereof, if applicable, and with any
         other applicable provisions of this agreement.
 
     (i) EVIDENCE AND AUTHORITY TO TRUSTEE.  VESI and/or Veritas shall furnish
         to the Trustee evidence of compliance with the conditions provided for
         in this agreement relating to any action or step required or permitted
         to be taken by VESI and/or Veritas or the Trustee under this agreement
         or
 
                                      F-14

        as a result of any obligation imposed under this agreement, including,
        without limitation, in respect of the Voting Rights or the Exchange
        Right or the Automatic Exchange Rights and the taking of any other
        action to be taken by the Trustee at the request of or on the
        application of VESI and/or Veritas forthwith if and when:
 
        (i)   such evidence is required by any other section of this agreement
              to be furnished to the Trustee in accordance with the terms of
              this Section 7(i); or
 
        (ii)  the Trustee, in the exercise of its rights, powers, duties and
              authorities under this agreement, gives VESI and/or Veritas
              written notice requiring it to furnish such evidence in relation
              to any particular action or obligation specified in such notice.
 
        Such evidence shall consist of an Officer's Certificate of VESI and/or
        Veritas or a statutory declaration or a certificate made by persons
        entitled to sign an Officer's Certificate stating that any such
        condition has been complied with in accordance with the terms of this
        agreement.
 
        Whenever such evidence relates to a matter other than the Voting Rights
        or the Exchange Right or the Automatic Exchange Rights, and except as
        otherwise specifically provided herein, such evidence may consist of a
        report or opinion of any solicitor, auditor, accountant, appraiser,
        valuer, engineer or other expert or any other person whose
        qualifications give authority to a statement made by him, provided that
        if such report or opinion is furnished by a director, officer or
        employee of VESI and/or Veritas it shall be in the form of an Officer's
        Certificate or a statutory declaration.
 
        Each statutory declaration, certificate, statement, opinion or report
        furnished to the Trustee as evidence of compliance with a condition
        provided for in this agreement shall include a statement by the person
        giving the evidence:
 
        (iii) declaring that he has read and understands the provisions of this
              agreement relating to the condition in question:

              investigation upon which he based the statutory declaration,
              certificate, statement, opinion or report; and
 
        (v)   declaring that he has made such examination or investigation as he
              believes is necessary to enable him to make the statements or give
              the opinions contained or expressed therein.
 
   (j)  EXPERTS, ADVISERS AND AGENTS.  The Trustee may:
 
        (i)   in relation to these presents act and rely on the opinion or
              advice of or information obtained from or prepared by any
              solicitor, auditor, accountant, appraiser, valuer, engineer or
              other expert, whether retained by the Trustee or by VESI and/or
              Veritas or otherwise, and may employ such assistants as may be
              necessary to the proper determination and discharge of its powers
              and duties and determination of its rights hereunder and may pay
              proper and reasonable compensation for all such legal and other
              advice or assistance as aforesaid; and
 
        (ii)  employ such agents and other assistants as it may reasonably
              require for the proper determination and discharge of its powers
              and duties hereunder, and may pay reasonable remuneration for all
              services performed for it (and shall be entitled to receive
              reasonable remuneration for all services performed by it) in the
              discharge of the trusts hereof and compensation for all
              disbursements, costs and expenses made or incurred by it in the
              determination and discharge of its duties hereunder and in the
              management of the Trust.
 
    (k)  INVESTMENT OF MONEYS HELD BY TRUSTEE.  Unless otherwise provided in
         this agreement, any moneys held by or on behalf of the Trustee which
         under the terms of this agreement may or ought to be invested or which
         may be on deposit with the Trustee or which may be in the hands of the
         Trustee may be invested and reinvested in the name or under the control
         of the Trustee in securities in which, under the laws of the Province
         of Alberta, trustees are authorized to invest trust moneys, provided
         that such securities are stated to mature within two years after their
         purchase by the Trustee, and the Trustee shall so invest such moneys on
         the written direction of VESI. Pending the investment F-15
<PAGE>   273
          of any moneys as hereinbefore provided, such moneys may be deposited
          in the name of the Trustee in any chartered bank in Canada or, with
          the consent of VESI, in the deposit department of the Trustee or any
          other loan or trust company authorized to accept deposits under the
          laws of Canada or any province thereof at the rate of interest then
          current on similar deposits.
 
     (l)  TRUSTEE NOT REQUIRED TO GIVE SECURITY.  The Trustee shall not be
          required to give any bond or security in respect of the execution of
          the trusts, rights, duties, powers and authorities of this agreement
          or otherwise in respect of the premises.
 
     (m)  TRUSTEE NOT BOUND TO ACT ON REQUEST.  Except as in this agreement
          otherwise specifically provided, the Trustee shall not be bound to act
          in accordance with any direction or request of VESI and/or Veritas or
          of the directors thereof until a duly authenticated copy of the
          instrument or resolution containing such direction or request shall
          have been delivered to the Trustee, and the Trustee shall be empowered
          to act and rely upon any such copy purporting to be authenticated and
          believed by the Trustee to be genuine.
 
     (n)  AUTHORITY TO CARRY ON BUSINESS.  The Trustee represents to VESI and
          Veritas that at the date of execution and delivery by it of this
          agreement it is authorized to carry on the business of a trust company
          in the Province of Alberta but if, notwithstanding the provisions of
          this Section 7(n), it ceases to be so authorized to carry on business,
          the validity and enforceability of this agreement and the Voting
          Rights, the Exchange Right and the Automatic Exchange Rights shall not
          be affected in any manner whatsoever by reason only of such event but
          the Trustee shall, within 90 days after ceasing to be authorized to
          carry on the business of a trust company in the Province of Alberta,
          either become so authorized or resign in the manner and with the
          effect specified in Article 10 hereof.
 
     (o)  CONFLICTING CLAIMS.  If conflicting claims or demands are made or
          asserted with respect to any interest of any Holder in any Series 1
          Exchangeable Shares, including any disagreement between the heirs,
          representatives, successors or assigns succeeding to all or any part
          of the interest of any Holder in any Series 1 Exchangeable Shares
          resulting in conflicting claims or demands being made in connection
          with such interest, then the Trustee shall be entitled, at its sole
          discretion, to refuse to recognize or to comply with any such claim or
          demand. In so refusing, the Trustee may elect not to exercise any
          Voting Rights, Exchange Right or Automatic Exchange Rights subject to
          such conflicting claims or demands and, in so doing, the Trustee shall
          not be or become liable to any person on account of such election or
          its failure or refusal to comply with any such conflicting claims or
          demands. The Trustee shall be entitled to continue to refrain from
          acting and to refuse to act until:
 
          (i)   the rights of all adverse claimants with respect to the Voting
                Rights, Exchange Right or Automatic Exchange Rights subject to
                such conflicting claims or demands have been adjudicated by a
                final judgment of a court of competent jurisdiction; or
 
          (ii)  all differences with respect to the Voting Rights, Exchange
                Right or Automatic Exchange Rights subject to such conflicting
                claims or demands have been conclusively settled by a valid
                written agreement binding on all such adverse claimants, and the
                Trustee shall have been furnished with an executed copy of such
                agreement.
 
          If the Trustee elects to recognize any claim or comply with any demand
          made by any such adverse claimant, it may in its discretion require
          such claimant to furnish such surety bond or other security
          satisfactory to the Trustee as it shall deem appropriate fully to
          indemnify it as between all conflicting claims or demands.
 
     (p)  ACCEPTANCE OF TRUST.  The Trustee hereby accepts the Trust created and
          provided for by and in this agreement and agrees to perform the same
          upon the terms and conditions herein set forth and to hold all rights,
          privileges and benefits conferred hereby and by law in trust for the
          various persons who shall from time to time be Holders, subject to all
          the terms and conditions herein set forth.

8.   COMPENSATION
 
     (a)  Veritas and VESI jointly and severally agree to pay to the Trustee
          reasonable compensation for all of the services rendered by it under
          this agreement and will reimburse the Trustee for all reasonable
          expenses (including but not limited to taxes, compensation paid to
          experts, agents and advisors and travel expenses) and disbursements,
          including the cost and expense of any suit or litigation of any
          character and any proceedings before any governmental agency
          reasonably incurred by the Trustee in connection with its rights and
          duties under this agreement; provided that Veritas and VESI shall have
          no obligation to reimburse the Trustee for any expenses or
          disbursements paid, incurred or suffered by the Trustee in any suit or
          litigation in which the Trustee is determined to have acted in bad
          faith or with negligence or willful misconduct.
 
9.   INDEMNIFICATION AND LIMITATION OF LIABILITY
 
     (a)  INDEMNIFICATION OF THE TRUSTEE.  Veritas and VESI jointly and
          severally agree to indemnify and hold harmless the Trustee and each of
          its directors, officers, employees and agents appointed and acting in
          accordance with this agreement (collectively, the "Indemnified
          Parties") against all claims, losses, damages, costs, penalties, fines
          and reasonable expenses (including reasonable expenses of the
          Trustee's legal counsel on a solicitor and his own client basis)
          which, without fraud, negligence, willful misconduct or bad faith on
          the part of such Indemnified Party, may be paid, incurred or suffered
          by the Indemnified Party by reason of or as a result of the Trustee's
          acceptance or administration of the Trust, its compliance with its
          duties set forth in this agreement, or any written or oral
          instructions delivered to the Trustee by Veritas or VESI pursuant
          hereto. In no case shall Veritas or VESI be liable under this
          indemnity for any claim against any of the Indemnified Parties unless
          Veritas and VESI shall be notified by the Trustee of the written
          assertion of a claim or of any action commenced against the
          Indemnified Parties, promptly after any of the Indemnified Parties
          shall have received any such written assertion of a claim or shall
          have been served with a summons or other first legal process giving
          information as to the nature and basis of the claim. Subject to (ii),
          below, Veritas and VESI shall be entitled to participate at their own
          expense in the defense and, if Veritas or VESI so elect at any time
          after receipt of such notice, either of them may assume the defense of
          any suit brought to enforce any such claim. The Trustee shall have the
          right to employ separate counsel in any such suit and participate in
          the defense thereof but the fees and expenses of such counsel shall be
          at the expense of the Trustee unless: (i) the employment of such
          counsel has been authorized by Veritas or VESI, such authorization not
          to be unreasonably withheld; or (ii) the named parties to any such
          suit include both the Trustee and Veritas or VESI and the Trustee
          shall have been advised by counsel acceptable to Veritas or VESI that
          there may be one or more legal defenses available to the Trustee that
          are different from or in addition to those available to Veritas or
          VESI and that an actual or potential conflict of interest exists (in
          which case Veritas and VESI shall not have the right to assume the
          defense of such suit on behalf of the Trustee but shall be liable to
          pay the reasonable fees and expenses of counsel for the Trustee).
 
     (b)  LIMITATION OF LIABILITY.  The Trustee shall not be held liable for any
          loss which may occur by reason of depreciation of the value of any
          part of the Trust Estate or any loss incurred on any investment of
          funds pursuant to this agreement, except to the extent that such loss
          is attributable to the fraud, negligence, willful misconduct or bad
          faith on the part of the Trustee.
 
10. CHANGE OF TRUSTEE
 
     (a)  RESIGNATION.  The Trustee, or any trustee hereafter appointed, may at
          any time resign by giving written notice of such resignation to
          Veritas and VESI specifying the date on which it desires to resign,
          provided that such notice shall never be given less than 60 days
          before such desired resignation date unless Veritas and VESI otherwise
          agree and provided further that such resignation shall not take effect
          until the date of the appointment of a successor trustee and the
          acceptance of such appointment by the successor trustee. Upon
          receiving such notice of resignation, Veritas and VESI shall promptly
          appoint a successor trustee by written instrument in duplicate, one
          copy of which shall be delivered to
                                      F-17
<PAGE>   275
          the resigning trustee and one copy to the successor trustee. Failing
          acceptance by a successor trustee, a successor trustee may be
          appointed by an order of the Alberta Court of Queen's Bench upon
          application of one or more of the parties hereto.
 
     (b)  REMOVAL.  The Trustee, or any trustee hereafter appointed, may be
          removed with or without cause, at any time on 60 days' prior notice by
          written instrument executed by Veritas and VESI, in duplicate, one
          copy of which shall be delivered to the trustee so removed and one
          copy to the successor trustee, provided that, in connection with such
          removal, provision is made for a replacement trustee similar to that
          contemplated in Section 10(a).
 
     (c)  SUCCESSOR TRUSTEE.  Any successor trustee appointed as provided under
          this agreement shall execute, acknowledge and deliver to Veritas and
          VESI and to its predecessor trustee an instrument accepting such
          appointment. Thereupon the resignation or removal of the predecessor
          trustee shall become effective and such successor trustee, without any
          further act, deed or conveyance, shall become vested with all the
          rights, powers, duties and obligations of its predecessor under this
          agreement, with like effect as if originally named as trustee in this
          agreement. However, on the written request of Veritas and VESI or of
          the successor trustee, the trustee ceasing to act shall, upon payment
          of any amounts then due it pursuant to the provisions of this
          agreement, execute and deliver an instrument transferring to such
          successor trustee all the rights and powers of the trustee so ceasing
          to act. Upon the request of any such successor trustee, Veritas, VESI
          and such predecessor trustee shall execute any and all instruments in
          writing for more fully and certainly vesting in and confirming to such
          successor trustee all such rights and powers.
 
     (d)  NOTICE OF SUCCESSOR TRUSTEE.  Upon acceptance of appointment by a
          successor trustee as provided herein, Veritas and VESI shall cause to
          be mailed notice of the succession of such trustee hereunder to each
          Holder specified in a List. If Veritas or VESI shall fail to cause
          such notice to be mailed within 10 days after acceptance of
          appointment by the successor trustee, the successor trustee shall
          cause such notice to be mailed at the expense of Veritas and VESI.
 
11. VERITAS SUCCESSORS
 
     (a)  CERTAIN REQUIREMENTS IN RESPECT OF COMBINATION, ETC.  Veritas shall
          not enter into any transaction (whether by way of reconstruction,
          reorganization, consolidation, merger, amalgamation, transfer, sale,
          lease or otherwise) whereby all or substantially all of its
          undertaking, property and assets would become the property of any
          other Person or, in the case of a merger or amalgamation, of the
          continuing corporation resulting therefrom unless, but may do so if:
 
          (i)  such other Person or continuing corporation (the "Veritas
               Successor"), by operation of law, becomes, without further
               action, bound by the terms and provisions of this agreement or,
               if not so bound, executes, prior to or contemporaneously with the
               consummation of such transaction an agreement supplemental hereto
               and such other instruments (if any) as are satisfactory to the
               Trustee and in the opinion of legal counsel to the Trustee are
               necessary or advisable to evidence the assumption by the Veritas
               Successor of liability for all moneys payable and property
               deliverable hereunder and the covenant of such Veritas Successor
               to pay and deliver or cause to be delivered the same and its
               agreement to observe and perform all the covenants and
               obligations of Veritas under this agreement; and
 
          (ii) such transaction shall, to the satisfaction of the Trustee and in
               the opinion of legal counsel to the Trustee, be upon such terms
               as substantially to preserve and not to impair in any material
               respect any of the rights, duties, powers and authorities of the
               Trustee or of the Holders hereunder.
 
     (b)  VESTING OF POWERS IN SUCCESSOR.  Whenever the conditions of Section
          11(a) hereof have been duly observed and performed, the Trustee, if
          required, by Section 11(a) hereof, the Veritas Successor and VESI
          shall execute and deliver the supplemental agreement provided for in
          Article 12 hereof and thereupon the Veritas Successor shall possess
          and from time to time may exercise each and
 
                                      F-18
<PAGE>   276
          every right and power of Veritas under this agreement in the name of
          Veritas or otherwise and any act or proceeding by any provision of
          this agreement required to be done or performed by the board of
          directors of Veritas or any officers of Veritas may be done and
          performed with like force and effect by the directors or officers of
          such Veritas Successor.
 
     (c)  WHOLLY-OWNED SUBSIDIARIES.  Nothing herein shall be construed as
          preventing the amalgamation or merger of any wholly-owned subsidiary
          of Veritas with or into Veritas or the winding-up, liquidation or
          dissolution of any wholly-owned subsidiary of Veritas provided that
          all of the assets of such subsidiary are transferred to Veritas or
          another wholly-owned subsidiary of Veritas, and any such transactions
          are expressly permitted by this Article 11.
 
12. AMENDMENTS AND SUPPLEMENTAL AGREEMENTS
 
     (a)  AMENDMENTS, MODIFICATIONS, ETC.  This agreement may not be amended or
          modified except by an agreement in writing executed by VESI, Veritas
          and the Trustee and approved by the Holders in accordance with Section
          9.2 of the Exchangeable Share Provisions.
 
     (b)  MINISTERIAL AMENDMENTS.  Notwithstanding the provisions of Section
          12(a) hereof, the parties to this agreement may in writing, at any
          time and from time to time, without the approval of the Holders, amend
          or modify this agreement for the purposes of:
 
          (i)   adding to the covenants of any or all of the parties hereto for
                the protection of the Holders hereunder;
 
          (ii)  making such amendments or modifications not inconsistent with
                this agreement as may be necessary or desirable with respect to
                matters or questions which, in the opinion of the board of
                directors of each of Veritas and VESI and in the opinion of the
                Trustee and its counsel, having in mind the best interests of
                the Holders as a whole, it may be expedient to make, provided
                that such boards of directors and the Trustee and its counsel
                shall be of the opinion that such amendments and modifications
                will not be prejudicial to the interests of the Holders as a
                whole; or
 
          (iii) making such changes or corrections which, on the advice of
                counsel to VESI, Veritas and the Trustee, are required for the
                purpose of curing or correcting any ambiguity or defect or
                inconsistent provision or clerical omission or mistake or
                manifest error, provided that the Trustee and its counsel and
                the board of directors of each of VESI and Veritas shall be of
                the opinion that such changes or corrections will not be
                prejudicial to the interests of the Holders as a whole.
 
     (c)  MEETING TO CONSIDER AMENDMENTS.  VESI, at the request of Veritas,
          shall call a meeting or meetings of the Holders for the purpose of
          considering any proposed amendment or modification requiring approval
          pursuant hereto. Any such meeting or meetings shall be called and held
          in accordance with the by-laws of VESI, the Exchangeable Share
          Provisions and all applicable laws.
 
     (d)  CHANGES IN CAPITAL OF VERITAS AND VESI.  At all times after the
          occurrence of any event effected pursuant to Section 2(g) or Section
          2(h) of the Support Agreement, as a result of which either Veritas
          Common Stock or the Series 1 Exchangeable Shares or both are in any
          way changed, this agreement shall forthwith be amended and modified as
          necessary in order that it shall apply with full force and effect,
          mutatis mutandis, to all new securities into which Veritas Common
          Stock or the Series 1 Exchangeable Shares or both are so changed and
          the parties hereto shall execute and deliver a supplemental agreement
          giving effect to and evidencing such necessary amendments and
          modifications.
 
     (e)  EXECUTION OF SUPPLEMENTAL AGREEMENTS.  No amendment to or
          modification or waiver of any of the provisions of this agreement
          otherwise permitted hereunder shall be effective unless made in
          writing and signed by all of the parties hereto. From time to time
          VESI (when authorized by a resolution of its Board of Directors),
          Veritas (when authorized by a resolution of its board of directors)
 
                                      F-19
<PAGE>   277
          and the Trustee may, subject to the provisions of these presents, and
          they shall, when so directed by these presents, execute and deliver by
          their proper officers, agreements or other instruments supplemental
          hereto, which thereafter shall form part hereof, for any one or more
          of the following purposes:
 
          (i)   evidencing the succession of any Veritas Successors to Veritas
                and the covenants of and obligations assumed by each such
                Veritas Successors in accordance with the provisions of Article
                11 and the successor of any successor trustee in accordance with
                the provisions of Article 10;
 
          (ii)  making any additions to, deletions from or alterations of the
                provisions of this agreement or the Voting Rights, the Exchange
                Right or the Automatic Exchange Rights which, in the opinion of
                the Trustee and its counsel, will not be prejudicial to the
                interests of the Holders as a whole or are in the opinion of
                counsel to the Trustee necessary or advisable in order to
                incorporate, reflect or comply with any legislation the
                provisions of which apply to Veritas, VESI, the Trustee or this
                agreement; and
 
          (iii) for any other purposes not inconsistent with the provisions of
                this agreement, including without limitation to make or evidence
                any amendment or modification to this agreement as contemplated
                hereby, provided that, in the opinion of the Trustee and its
                counsel, the rights of the Trustee and the Holders as a whole
                will not be prejudiced thereby.

     Section 1.  The aggregate number of shares which the Corporation will have
authority to issue is 41,000,000, of which 40,000,000 will be common shares, par
value $.01 per share, ("Ordinary Shares") and 1,000,000 will be shares of

     Section 2.  Preferred Stock.  Shares of Preferred Stock may be issued from
time to time in one or more series, each of which is to have a distinctive
designation specified in the resolution or resolutions of the Board of Directors
providing for the issuance of such Preferred Stock from time to time. Each
series of Preferred Stock:
 
     (a)   may have such number of shares;
 
     (b)   may have such voting powers, full or limited;
 
     (c)   may be subject to redemption upon such terms and conditions;
 
     (d)   may be entitled to receive dividends (which may be cumulative or
           noncumulative) payable in cash, property, rights or securities at
           such rate or rates, on such conditions, from such date or dates, and
           at such times, and payable in preference to, or in such relation to,
           the dividends payable on any other class or series of stock;
                                       G-1
<PAGE>   282
 
     (e)   may have such rights and preferences upon the dissolution or
           liquidation (whether voluntary or involuntary) of the Corporation;
 
     (f)   may be made convertible into or exchangeable for other securities, or

     shares comprising such series may be increased or decreased (but not below

     the Board of Directors. Shares of any series of Preferred Stock, which have
     been redeemed (whether through the operation of a sinking fund or
     otherwise) by the Corporation, or which, if convertible or exchangeable,
     have been converted into or exchanged for shares of stock of any other
     class, will have the status of authorized but unissued shares of Preferred
     Stock and may be reissued as a part of the series of which they were
     originally a part or may be reclassified and reissued as part of a new
     series of Preferred Stock created by resolution or resolutions of the Board
     of Directors or as part of any other series of Preferred Stock, all subject
     to the conditions or restrictions on issuance set forth in the resolution
     or resolutions adopted by the Board of Directors providing for the issuance
     of any series of Preferred Stock and to any filing required by law.
 
     Section 3.  Ordinary Shares.  Ordinary Shares may be issued from time to
time in one or more series. The designations, powers, preferences and relative,
participating, optional and other special rights, and the qualifications,
limitations and restrictions thereon, of the Ordinary Shares of each series
shall be such as are stated and expressed herein, and to the extent not stated
and expressed herein, shall be such as may be fixed by the Board of Directors
and stated and expressed in the resolution or resolutions providing for the
issuance of such Ordinary Shares from time to time; provided, however, that:
 
     (a)   except as otherwise provided by law or by the resolution or
           resolutions of the Board of Directors providing for the issuance of
           any series of Preferred Stock, Ordinary Shares will have the
           exclusive right to vote for the election of directors and for all
           other purposes; and
 
     (b)   all outstanding Ordinary Shares shall vote together as a single class
           on all matters presented to stockholders, with each outstanding share
           of each series of Ordinary Shares to have such number of votes as
           specified herein or as set forth in the resolution or resolutions of
           the Board of Directors authorizing such series.
 
     Section 4.A.  VESI Special Voting Stock Designated.  A series of previously
outstanding Ordinary Shares, consisting of one such share, has been duly
designated as "Special Voting Stock" (hereinafter referred to as the "VESI
Special Voting Stock"). Each outstanding share of VESI Special Voting Stock
shall be entitled at any relevant date to the number of votes determined in
accordance with the "Plan of Arrangement" (as that term is defined in that
certain "Combination Agreement" dated as of May 10, 1996 (hereinafter referred
to as the "VESI Combination Agreement"), by and between Digicon Inc. and Veritas
Energy Services Inc. ("VESI")) on all matters presented to the stockholders. No
dividend or distribution of assets shall be paid to the holders of VESI Special
Voting Stock. The VESI Special Voting Stock is not convertible into any other
class or series of the capital stock of the Corporation or into cash, property
or other rights, and may not be redeemed. Any shares of VESI Special Voting
Stock purchased or otherwise acquired by the Corporation shall be deemed retired
and shall be canceled and may not thereafter be reissued or otherwise disposed
of by the Corporation. So long as any "VESI Exchangeable Shares" (i.e.,
"Exchangeable Shares," as that term is defined in the VESI Combination
Agreement) shall be outstanding, the number of shares comprising the VESI
Special Voting Stock shall not be
 
                                       G-2
<PAGE>   283

be amended, except upon the unanimous approval of all outstanding Ordinary
Shares.
 
     Section 4.B.  ERS Special Voting Stock Designated.  A series of Ordinary
Shares, consisting of one such share, is hereby designated as "ERS Special
Voting Stock" (hereinafter referred to as "ERS Special Voting Stock"). Each
outstanding share of ERS Special Voting Stock shall be entitled at any relevant
date to the number of votes determined in accordance with the "Plan of
Arrangement" (as that term is defined in that certain "Combination Agreement"
dated as of March 30, 1999 (hereinafter referred to as the "ERS Combination
Agreement") by and among Veritas DGC Inc., VESI and Enertec Resource Services
Inc. ("ERS")) on all matters presented to the stockholders. No dividend or
distribution of assets shall be paid to the holders of ERS Special Voting Stock.
The ERS Special Voting Stock is not convertible into any other class or series
of the capital stock of the Corporation or into cash, property or other rights,
and may not be redeemed. Any shares of ERS Special Voting Stock purchased or
otherwise acquired by the Corporation shall be deemed retired and shall be
canceled and may not thereafter be reissued or otherwise disposed of by the
Corporation. So long as any "ERS Exchangeable Shares" (i.e., "Series 1
Exchangeable Shares," as that term is defined in the ERS Combination Agreement)
shall be outstanding, the number of shares comprising the ERS Special Voting
Stock shall not be increased or decreased and no other term of the ERS Special
Voting Stock shall be amended, except upon the unanimous approval of all
outstanding Ordinary Shares.
 
     Section 4.C.  Miscellaneous.  Any reference herein to "Exchangeable Shares"
encompasses both the VESI Exchangeable Shares and the ERS Exchangeable Shares.
 
     Section 5.  Common Stock Designated.  All Ordinary Shares not otherwise
designated as to series herein or in a resolution of the Board of Directors
creating another series of Ordinary Shares, is designated as "Common Stock."
Such resulting number of shares may be decreased by resolution of the Board of
Directors and without stockholder action; provided, however, that no decrease
shall reduce the number of shares of Common Stock to a number less than the
number of shares then outstanding plus the number of shares reserved for
issuance upon the exercise of outstanding options, rights and/or warrants, the
conversion of any outstanding convertible securities and/or the exchange of any
outstanding exchangeable securities which are directly or indirectly exercisable
for, convertible into or exchangeable for Common Stock. Each outstanding share
of Common Stock shall be entitled to one vote on all matters presented to the
stockholders. Subject to the rights and preferences of any Preferred Stock which
may be designated and issued, the holders of Common Stock are entitled (i) to
receive such dividends as may be declared thereon from time to time by the Board
of Directors in its discretion, out of any assets of the Corporation at the time
legally available for the payment of dividends and (ii) in the event of
liquidation, dissolution or winding up of the affairs of the Corporation,
whether voluntary or involuntary, or in the event of its insolvency, to receive
any net assets of the Corporation remaining after the holders of any other
classes or series of the Corporation's capital stock which by their respective
terms are senior to the Common Stock as to dividends and distributions of assets
have been paid in full the amounts to which they respectively are entitled or a
sum sufficient for such payment in full has been set aside.
 
     Section 6.  No holder of securities of the Corporation shall have any
preemptive right to acquire any shares or securities of any kind, whether now or
hereafter authorized, which may at any time be issued, sold or offered for sale
by the Corporation.
 
                                   ARTICLE V
 
     The existence of the Corporation is to be perpetual.
 
                                   ARTICLE VI
 
     In furtherance and not in limitation of the powers conferred by statute,
the Board of Directors is expressly authorized:
 
     (a)   to authorize and cause to be executed mortgages and liens upon the
           real and personal property of the Corporation;
 
                                       G-3
<PAGE>   284
 
     (b)   to set apart out of any of the funds of the Corporation available for
           dividends a reserve or reserves for any proper purpose and to abolish
           any such reserve in the manner in which it was created; and
 
     (c)   when and as authorized by the affirmative vote of the holders of a
           majority of the stock issued and outstanding having voting power
           given at a stockholders' meeting duly called upon such notice as is
           required by statute to sell, lease or exchange all or substantially
           all of the property and assets of the Corporation, including its
           goodwill and its corporate franchises, upon such terms and conditions
           and for such consideration, which may consist in whole or in part of
           money or property including securities of any other corporation or
           corporations, as the Board of Directors shall deem expedient and for
           the best interests of the Corporation.
 
                                  ARTICLE VII
 
     Meetings of stockholders may be held within or without the State of
Delaware, at such date and time as is requested by the person or persons calling
the meeting, within the limits fixed by law. Special meetings of stockholders of
the Corporation for any purpose or purposes may only be called by a majority of
the entire Board of Directors, by the Chairman of the Board or the President of
the Corporation. Special meetings may not be called by any other person or
persons. The books of the Corporation may be kept (subject to any provision
contained in the statutes) outside the State of Delaware at such place or places
as may be designated from time to time by the Board of Directors or in the
Bylaws of the Corporation. Elections of directors need not be by written ballot
unless the Bylaws of the Corporation shall so provide.
 
                                  ARTICLE VIII
 
     The Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Restated Certificate of Incorporation (with
Amendments), in the manner now or hereafter prescribed by statute, and all
rights conferred upon stockholders herein are granted subject to this
reservation.
 
                                   ARTICLE IX
 
     The number of directors of the Corporation shall be not less than three nor
more than ten, the exact number to be fixed by the Board of Directors as
provided in the Bylaws. Any vacancy created by an increase in the number of
directors in accordance with the Bylaws may only be filled by the Board of
Directors. A director of the Corporation may only be removed by a majority vote
of the stockholders entitled to elect such director.
 
                                   ARTICLE X
 
     No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director; provided, however, that the foregoing clause shall not apply
to any liability of a director (i) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the Delaware General Corporation Law, or (iv)
for any transaction from which the director derived an improper personal
benefit.
 
     If the Delaware General Corporation Law hereafter is amended to authorize
the further elimination or limitation of the liability of directors, then the
liability of a director of the Corporation, in addition to the limitation on
personal liability provided herein, shall be limited to the fullest extent
permitted by the amended Delaware General Corporation Law. Any repeal or
modification of this paragraph by the stockholders of the Corporation shall be
prospective only, and shall not adversely affect any limitation on the personal
liability of a director of the Corporation existing at the time of such repeal
or modification.
 
     The Corporation shall indemnify its officers and directors to the fullest
extent permitted by the Delaware General Corporation Law as the same may be in
effect from time to time.

Exchangeable Shares are outstanding, the Corporation shall (i) fully comply with

The Board of Directors
ENERTEC Resource Services Inc.

To the Board of Directors:
 
We understand that ENERTEC Resource Services Inc. (the "Company" or "ENERTEC"),
Veritas DGC Inc. ("Veritas") and Veritas Energy Services Inc. propose to enter
into a Combination Agreement anticipated to be dated as of March 30, 1999 which
contemplates an arrangement (the "Arrangement") pursuant to which holders of
ENERTEC common shares ("ENERTEC Common Shares") will receive exchangeable shares
(the "Exchangeable Shares") of Veritas Energy Services Inc. (a subsidiary of
Veritas) in exchange for their ENERTEC Common Shares at a ratio of 0.345
Exchangeable Shares for each ENERTEC Common Share. Each Exchangeable Share will
be exchangeable, at the option of the holder, for one share of Veritas common

        (b)   if the corporation did not send notice to the shareholder of the
              purpose of the meeting or of his right to dissent, within a
              reasonable time after he learns that the resolution was adopted
              and of his right to dissent.
 
     (6)   An application may be made to the Court by originating notice after
the adoption of a resolution referred to in subsection (1) or (2),
 
        (a)   by the corporation, or

shareholder who dissents under this section.
 
     (7)   If an application is made under subsection (6), the corporation

     (10)  A dissenting shareholder may make an agreement with the corporation

     (11)  A dissenting shareholder
 
        (a)   is not required to give security for costs in respect of an
              application under subsection (6), and

              favour of each of those dissenting shareholders, and
 
        (c)   fixing the time within which the corporation must pay that amount
              to a shareholder.
 
(14)  On
 
        (a)   the action approved by the resolution from which the shareholder
              dissents becoming effective,
 
        (b)   the making of an agreement under subsection (10) between the
              corporation and the dissenting shareholder as to the payment to be
              made by the corporation for his shares, whether by the acceptance
              of the corporation's offer under subsection (7) or otherwise, or
 
        (c)   the pronouncement of an order under subsection (13),
 
whichever first occurs, the shareholder ceases to have any rights as a
shareholder other than the right to be paid the fair value of his shares in the
amount agreed to between the corporation and the shareholder or in the amount of
the judgment, as the case may be,
 
(15)  Subsection (14)(a) does not apply to a shareholder referred to in
     subsection (5)(b).
 
(16)  Until one of the events mentioned in subsection (14) occurs,
 
        (a)   the shareholder may withdraw his dissent, or

                                       I-2
<PAGE>   293
 
(17)  The Court may in its discretion allow a reasonable rate of interest on the
      amount payable to each dissenting shareholder, from the date on which the
      shareholder ceases to have any rights as a shareholder by reason of
      subsection (14) until the date of payment.
 
(18)  If subsection (20) applies, the corporation shall, within 10 days after
 
        (a)   the pronouncement of an order under subsection (13), or
 
        (b)   the making of an agreement between the shareholder and the
              corporation as to the payment to be made for his shares,
 
        notify each dissenting shareholder that it is unable lawfully to pay
        dissenting shareholders for their shares.
 
(19)  Notwithstanding that a judgment has been given in favour of a dissenting
      shareholder under subsection (13)(b), if subsection (20) applies, the
      dissenting shareholder, by written notice delivered to the corporation
      within 30 days after receiving the notice under subsection (18), may
      withdraw his notice of objection, in which case the corporation is deemed
      to consent to the withdrawal and the shareholder is reinstated to his full
      rights as a shareholder, failing which he retains a status as a claimant
      against the corporation, to be paid as soon as the corporation is lawfully
      able to do so or, in a liquidation, to be ranked subordinate to the rights
      of the creditors of the corporation but in priority to its shareholders.
 
(20)  A corporation shall not make a payment to a dissenting shareholder under
      this section if there are reasonable grounds for believing that
 
        (a)   the corporation is or would after the payment be unable to pay its
              liabilities as they become due, or
 
        (b)   the realizable value of the corporation's assets would thereby be
              less than the aggregate of its liabilities.
