the offer by Tiger Acquisition Corporation, a Delaware corporation
("Purchaser"), and a wholly-owned subsidiary of International Technology
Corporation, a Delaware corporation doing business as The IT Group, Inc.
("Parent"), to purchase all of the issued and outstanding shares (the "Shares")
of common stock, par value $.001 per share (the "Common Stock"), of Fluor Daniel
GTI, Inc., a Delaware corporation (the "Company"), at a price of $8.25 per
Share, net to each seller in cash, without interest (such amount, or any greater
amount per share paid pursuant to the Offer (as defined below) being hereinafter
referred to as the "Offer Price"), upon the terms and subject to the conditions
set forth in the Offer to Purchase, dated as of November 3, 1998 (the "Offer to
Purchase"), and the related Letter of Transmittal (the "Letter of Transmittal,"
which, together with the Offer to Purchase, constitute the "Offer"), copies of
which are attached hereto as Exhibits (a)(1) and (a)(2), respectively.  The
Offer is being made pursuant to the terms of the Agreement and Plan of Merger
(the "Merger Agreement"), dated as of October 27, 1998, by and among Parent,

which provides, among other things, for the commencement of the Offer by
Purchaser and further provides that, following the purchase of Shares pursuant

with the Company continuing as the surviving corporation.  The consummation of
the Merger is subject to the satisfaction or, if permissible, waiver of certain
conditions, including approval of the adoption of the Merger Agreement by the
requisite vote of the stockholders of the Company.  If Purchaser acquires the
Minimum Share Number (as defined below) of Shares, it will acquire sufficient
Shares in the Offer to assure such stockholder approval.  If Purchaser acquires
at least 90% of the Shares in the Offer, under Delaware law it will be able to
consummate the Merger without a vote of the Company's stockholders

outstanding Share (other than Shares held by Parent, Purchaser or any other
direct or indirect subsidiary of Parent or Shares that are owned by the Company

retired without any payment with respect thereto, or Shares (the "Dissenting
Shares") with respect to which the holder properly exercises such holder's
appraisal rights in accordance with the Delaware General Corporation Law
("DGCL") (collectively, the "Excluded Shares")) shall be converted into, and
become exchangeable for the Offer Price, and the Offer Price multiplied by the
number of such Shares shall be referred to as the "Merger Consideration."

     At the Effective Time, all Shares other than Dissenting Shares shall be
canceled and retired and shall cease to exist, and each certificate formerly
representing any of such Shares (other than any Excluded Shares) shall
thereafter represent only the right to receive the Merger Consideration.

     The Offer is conditioned upon, among other things, there being validly
tendered prior to the Expiration Date and not withdrawn at least 4,400,000
Shares owned by FD, representing approximately 52.3% of the Shares as of October
30, 1998, and at least a majority of the

To the Holders of Common Stock of Fluor Daniel GTI, Inc.:
 
                                 INTRODUCTION
 
  Tiger Acquisition Corporation, a Delaware corporation ("Purchaser"), which
is a wholly-owned subsidiary of International Technology Corporation, a
Delaware corporation doing business as The IT Group, Inc. ("Parent"), hereby
offers to purchase all of the issued and outstanding shares (the "Shares") of
common stock, par value $.001 per share (the "Common Stock"), of the Company,
upon the terms and subject to the conditions set forth in this Offer to
Purchase, dated as of November 3, 1998 (the "Offer to Purchase"), and the
related Letter of Transmittal (which, together with the Offer to Purchase,
constitute the "Offer"), at a price of $8.25 per Share, net to each seller in
cash, without interest (such amount, or any greater amount per Share paid
pursuant to the Offer being hereinafter referred to as the "Offer Price").
 
  THE BOARD, ACTING ON THE UNANIMOUS RECOMMENDATION OF THE SPECIAL COMMITTEE,
HAS UNANIMOUSLY DETERMINED THAT THE MERGER AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED THEREBY, INCLUDING THE OFFER AND THE MERGER, ARE FAIR TO, AND IN
THE BEST INTERESTS OF THE STOCKHOLDERS OF THE COMPANY, HAS UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY,
INCLUDING THE OFFER AND THE MERGER, AND RECOMMENDS THAT THE STOCKHOLDERS
ACCEPT THE OFFER AND TENDER THEIR SHARES HEREUNDER.
 
  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED PRIOR TO THE EXPIRATION DATE AND NOT WITHDRAWN 4,400,000 SHARES (THE
"FD SHARES"), OWNED BY FLUOR DANIEL, INC., A CALIFORNIA CORPORATION ("FD") AND
CONSTITUTING APPROXIMATELY 52.3% OF THE SHARES, AND AT LEAST A MAJORITY OF THE
REMAINING ISSUED AND OUTSTANDING SHARES OF THE COMPANY. THE OFFER IS ALSO
SUBJECT TO CERTAIN OTHER CONDITIONS SET FORTH IN THIS OFFER TO PURCHASE. SEE
"THE TENDER OFFER--19. CERTAIN CONDITIONS OF THE OFFER."
 
  Pursuant to the Merger Agreement (as defined herein) FD has agreed, among
other things, to tender in, and not withdraw from, the Offer, all Shares
(including the FD Shares) owned by it and its affiliates. As of October 30,
1998, FD owned 4,400,000 Shares representing approximately 52.3% of the
Shares. As used in this Offer to Purchase, the "Minimum Condition" shall be
satisfied when the FD Shares and at least a majority of the Shares not owned
by FD are validly tendered, and not withdrawn, pursuant to the Offer. The
number of Shares that would satisfy the Minimum Condition is referred to
herein as the "Minimum Share Number."
 
  THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY
TIME, ON WEDNESDAY, DECEMBER 2, 1998, UNLESS EXTENDED. SEE "THE TENDER OFFER--
1. TERMS OF THE OFFER; EXPIRATION DATE."
 
  The Offer is being made pursuant to the terms of the Agreement and Plan of
Merger (the "Merger Agreement"), dated as of October 27, 1998, by and among
Parent, Purchaser, the Company and FD, which provides, among other things, for
the commencement of the Offer by Purchaser and further provides that,
following the purchase of Shares pursuant to the Offer, Purchaser will be
merged with and into the Company (the "Merger"), with the Company continuing
as the surviving corporation (the "Surviving Corporation"). The consummation
of the Merger is subject to the satisfaction or, if permissible, waiver of
certain conditions, including approval of the adoption of the Merger Agreement
by the requisite vote of the stockholders of the Company. If Purchaser
acquires the Minimum Share Number, it will have sufficient voting power to
approve and adopt the Merger Agreement and the Merger without the vote of any
other stockholder of the Company. If Purchaser acquires at least 90% of the
Shares in the Offer, under Delaware law it will be able to consummate the
Merger without a vote of the Company's stockholders.
 
  At the effective time of the Merger (the "Effective Time"), each issued and
outstanding Share (other than Shares held by Parent, Purchaser or any other
direct or indirect subsidiary of Parent or Shares that are owned by
<PAGE>
 
the Company or any direct or indirect subsidiary of the Company, which will be
canceled and retired without any payment with respect thereto, or Shares (the
"Dissenting Shares") with respect to which the holder properly exercises such
holder's appraisal rights in accordance with the Delaware General Corporation
Law ("DGCL") (collectively, the "Excluded Shares")) shall be converted into,
and become exchangeable for the Offer Price, and the Offer Price multiplied by
the number of such Shares shall be referred to as the "Merger Consideration."
 
  At the Effective Time, all Shares other than Dissenting Shares shall be
canceled and retired and shall cease to exist, and each certificate (a
"Certificate") formerly representing any of such Shares (other than any
Excluded Shares) shall thereafter represent only the right to receive the
Merger Consideration.
 
  BT ALEX. BROWN INCORPORATED ("BT ALEX. BROWN"), FINANCIAL ADVISOR TO THE
COMPANY, HAS DELIVERED A WRITTEN OPINION TO THE SPECIAL COMMITTEE AND THE
BOARD, DATED AS OF THE DATE OF THE MERGER AGREEMENT (THE "OPINION"), TO THE
EFFECT THAT, AS OF THAT DATE, THE CONSIDERATION TO BE RECEIVED BY THE
STOCKHOLDERS OF THE COMPANY (OTHER THAN FD AND PARENT AND THEIR RESPECTIVE
AFFILIATES) PURSUANT TO THE MERGER AGREEMENT IS FAIR FROM A FINANCIAL POINT OF
VIEW TO SUCH STOCKHOLDERS. THE FULL TEXT OF THE OPINION IS CONTAINED IN THE
COMPANY'S SOLICITATION/RECOMMENDATION STATEMENT ON SCHEDULE 14D-9 (THE
"SCHEDULE 14D-9") FILED WITH THE SECURITIES AND EXCHANGE COMMISSION (THE
"COMMISSION") IN CONNECTION WITH THE OFFER, A COPY OF WHICH IS BEING PROVIDED
TO STOCKHOLDERS CONCURRENTLY WITH THIS OFFER TO PURCHASE. STOCKHOLDERS ARE
URGED TO READ SUCH OPINION CAREFULLY AND IN ITS ENTIRETY.
 
  The Company has informed Purchaser that as of October 19, 1998 all of the
executive officers and directors of the Company as a group owned 37,326 Shares
and held options to purchase 265,388 shares of Common Stock. See "THE TENDER
OFFER--16. Interests of Certain Persons in the Offer and the Merger."
 
  The Offer and withdrawal rights will expire at 12:00 Midnight, New York City
time, on Wednesday, December 2, 1998, unless extended. See "THE TENDER OFFER--
1. Terms of the Offer; Expiration Date."
 
  THE OFFER DOES NOT CONSTITUTE A SOLICITATION OF PROXIES FOR ANY MEETING OF
THE COMPANY'S STOCKHOLDERS. ANY SUCH SOLICITATION, IF REQUIRED, WILL BE MADE
ONLY PURSUANT TO SEPARATE PROXY MATERIALS COMPLYING WITH THE REQUIREMENTS OF
SECTION 14(a) OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED (THE
"EXCHANGE ACT").
 
  Tendering stockholders will not be obligated to pay brokerage commissions,
solicitation fees or, subject to Instruction 6 of the Letter of Transmittal,
stock transfer taxes on the purchase of Shares by Purchaser pursuant to the
Offer. However, any tendering stockholder or other payee who fails to complete
and sign the Substitute Form W-9 that is included in the Letter of Transmittal
may be subject to a required backup federal income tax withholding of 31% of
the gross proceeds payable to such stockholder or other payee pursuant to the
Offer. See "THE TENDER OFFER--5. Certain Federal Income Tax Consequences."
Purchaser will pay all charges and expenses of BankBoston, N.A., as Depositary
(in such capacity, the "Depositary"), and MacKenzie Partners, Inc., as
Information Agent (in such capacity, the "Information Agent"), incurred in
connection with the Offer. For a description of the fees and expenses to be
paid by Purchaser, see "THE TENDER OFFER--21. Fees and Expenses."
 
  Consummation of the Merger is subject to a number of conditions, including
approval of the Merger Agreement and the transactions contemplated thereby by
the stockholders of the Company. See "THE TENDER OFFER--20. Certain Legal
Matters; Regulatory Approvals." The Board has recommended that the Company's
stockholders approve the Merger and has taken all lawful action to solicit
such approval. If Purchaser acquires the Minimum Share Number in the Offer, it
will have sufficient voting power to approve and adopt the Merger
 
                                       2
<PAGE>
 
Agreement and the Merger without the vote of any other stockholder of the
Company. If Purchaser acquires at least 90% of the Shares in the Offer, under
Delaware law it will be able to consummate the Merger without a vote of the
Company's stockholders.
 
  The information contained in this Offer to Purchase concerning the Company,
including, without limitation, information concerning the deliberations,
approvals and recommendations of the Special Committee and the Board in
connection with the transaction, the Opinion, and the Company's capital
structure and historical and projected financial information, was supplied by
the Company. The information contained in this Offer to Purchase concerning
the Offer, the Merger, Parent and Purchaser was supplied by Purchaser.
 
  THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS

                               THE TENDER OFFER
 
1. TERMS OF THE OFFER; EXPIRATION DATE.
 
  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension
or amendment), Purchaser will accept for payment and pay for all of the Shares
validly tendered pursuant to the Offer prior to the Expiration Date (as
defined below) and not withdrawn in accordance with the provisions set forth
in this Offer to Purchase under the caption "THE TENDER OFFER--3. Withdrawal
Rights." The term "Expiration Date" shall mean 12:00 Midnight, New York City
time, on Wednesday, December 2, 1998, unless and until Parent, in its sole
discretion (but subject to restrictions contained in the Merger Agreement),
shall from time to time have extended the period of time during which the
Offer is open, in which event the term "Expiration Date" shall mean the latest
time and date at which the Offer, as so extended by Parent, shall expire. Any
determination concerning the satisfaction of the terms and conditions of the
Offer will be made by Purchaser in its good faith judgment and such
determination will be final and binding on all tendering stockholders.
 
  Parent expressly reserves the right to increase the Offer Price or to make
any other changes in the terms and conditions of the Offer, provided that,
unless previously approved by the Special Committee and the Board in writing,
no change may be made which (i) decreases the Offer Price, (ii) changes the
form of consideration payable in the Offer, (iii) reduces the maximum number
of Shares to be purchased in the Offer, (iv) amends the conditions to the
Offer set forth in "THE TENDER OFFER--19. Certain Conditions of the Offer" to
broaden their scope, (v) imposes additional conditions of the Offer or amend
any other term of the Offer in any manner adverse to holders of Shares or
extend the Offer if all of the conditions to the Offer are satisfied or
waived, or (vi) amends the Minimum Condition. See paragraph (f) of "THE TENDER
OFFER--19. Certain Conditions of the Offer."
 
  As used in this Offer to Purchase, "business day" means any day other than a
day on which banks in the State of New York are authorized to close or the New
York Stock Exchange (the "NYSE") is closed. Parent expressly reserves the
right, in its sole discretion (but subject to the terms and conditions of the
Merger Agreement), at any time and from time to time, without the consent of
the Special Committee and the Board to (i) from time to time extend the Offer
(each such individual extension not to exceed ten (10) business days after the
previously scheduled Expiration Date), if at the scheduled Expiration Date of
the Offer any of the conditions to the Offer shall not have been satisfied or
waived, until such time as such conditions are satisfied or waived;
(ii) extend the Offer for any period required by any rule, regulation,
interpretation or position of the Commission or the staff thereof applicable
to the Offer; or (iii) extend the Offer for any reason on up to two
(2) occasions in each case for a period of not more than five (5) business
days beyond the latest Expiration Date that would otherwise be permitted under
clause (i) or (ii) of this sentence if on such Expiration Date there shall
 
                                       3
<PAGE>
 
have been tendered more than the number of Shares sufficient to satisfy the
Minimum Condition but less than 90% of the Shares, provided the Purchaser
agrees to permanently waive the conditions set forth in paragraphs (b) and (e)
of "THE TENDER OFFER--19. Certain Conditions of the Offer." If all of the
conditions to the Offer set forth in "THE TENDER OFFER--19. Certain Conditions
of the Offer" are not satisfied on any scheduled Expiration Date of the Offer
then, provided that all such conditions are reasonably capable of being
satisfied prior to December 31, 1998, Parent shall extend the Offer from time
to time (each such individual extension not to exceed ten (10) business days
after the previously scheduled Expiration Date) until such conditions are
satisfied or waived, provided that Parent shall not be required to extend the
Offer beyond December 31, 1998. Such extension by Parent shall be effected by
giving oral or written notice of such extension to the Depositary. During any
such extension, all Shares previously tendered and not withdrawn will remain
subject to the Offer, subject to the rights of a tendering stockholder to
withdraw such stockholder's Shares. See "THE TENDER OFFER--3. Withdrawal
Rights."
 
  Subject to the applicable regulations of the Commission, Purchaser also
expressly reserves the right, in its sole discretion (but subject to the terms
and conditions of the Merger Agreement), at any time and from time to time,
(i) to delay acceptance for payment of, or, regardless of whether such Shares
were theretofore accepted for payment, payment for, any Shares pending receipt
of any regulatory or governmental approval described in this Offer to Purchase
under the caption "THE TENDER OFFER--20. Certain Legal Matters; Regulatory
Approvals," (ii) to terminate the Offer and not accept for payment any Shares
upon the occurrence of any of the conditions specified in "THE TENDER OFFER--
19. Certain Conditions of the Offer," and (iii) to waive any condition or
otherwise amend the Offer in any respect, by giving oral or written notice of
such delay, termination, waiver or amendment to the Depositary and by making a
public announcement thereof. Purchaser acknowledges that (i) Rule 14e-1(c)
under the Exchange Act requires Purchaser to pay the consideration offered or
return the Shares tendered promptly after the termination or withdrawal of the
Offer and (ii) Purchaser may not delay acceptance for payment of, or payment
for (except as provided in clause (i) of the first sentence of this
paragraph), any Shares upon the occurrence of any of the conditions specified
in "THE TENDER OFFER--19. Certain Conditions of the Offer" without extending
the period of time during which the Offer is open.
 
  If Parent extends the Offer, or if Purchaser (whether before or after its
acceptance for payment of Shares) is delayed in its payment for Shares or is
unable to pay for Shares pursuant to the Offer for any reason, then, without
prejudice to Purchaser's rights under the Offer, the Depositary may retain
tendered Shares on behalf of Purchaser, and such Shares may not be withdrawn
except to the extent tendering stockholders are entitled to withdrawal rights
as described in this Offer to Purchase under the caption "THE TENDER OFFER--3.
Withdrawal Rights." However, the ability of Purchaser to delay payment for
Shares that Purchaser has accepted for payment is limited by Rule 14e-1(c)
under the Exchange Act.
 
  Any extension, amendment or termination of the Offer will be followed as
promptly as practicable by public announcement in accordance with the public
announcement requirements of Rule 14e-1(d) under the Exchange Act. Subject to
applicable law (including Rules 14d-4(c) and 14d-6(d) under the Exchange Act,
which require that any material change in the information published, sent or
given to stockholders in connection with the Offer be promptly disseminated to
stockholders in a manner reasonably designed to inform stockholders of such
change) and without limiting the manner in which Purchaser may choose to make
any public announcement, Purchaser shall have no obligation to publish,
advertise or otherwise communicate any such public announcement other than by
making a release to the Dow Jones News Service.
 
  The Company has provided Purchaser with the Company stockholder list, a
nonobjecting beneficial owners list, and security position listings for the
purpose of disseminating the Offer to holders of Shares. This Offer to
Purchase and the Letter of Transmittal and other relevant materials will be
mailed to record holders of Shares and furnished to brokers, dealers,
commercial banks, trust companies and similar persons whose names, or the
names of whose nominees, appear on the stockholder list or, if applicable, who
are listed as participants in a clearing agency's security position listing,
for subsequent transmittal to beneficial owners of Shares.

2. PROCEDURE FOR ACCEPTING THE OFFER AND TENDERING SHARES.
 
 VALID TENDER OF SHARES
 
  For a stockholder to validly tender Shares pursuant to the Offer, either
(a)(i) a properly completed and duly executed Letter of Transmittal (or
facsimile thereof), together with any required signature guarantees, or an
Agent's Message (as defined herein) in connection with a book-entry delivery
of Shares and any other required documents, must be timely received by the
Depositary at one of its addresses set forth on the back cover of the Offer to
Purchase and (ii) either certificates ("Share Certificates") for tendered
Shares must be timely received by the Depositary at one of such addresses or
such Shares must be timely delivered pursuant to the procedure for book-entry
transfer set forth herein (and a Book-Entry Confirmation (as defined herein)
timely received by the Depositary) or (b) the tendering stockholder must
comply with the guaranteed delivery procedures set forth herein and the Letter
of Transmittal.
 
 BOOK-ENTRY TRANSFERS
 
  The Depositary will establish an account with respect to the Shares at The
Depositary Trust Company (the "Book-Entry Transfer Facility") for purposes of
the Offer within two business days after the date of this Offer to Purchase.
Any financial institution that is a participant in the Book-Entry Transfer
Facility may make book-entry delivery of the Shares by causing the book-entry
transfer system to transfer such Shares into the Depositary's account at the
Book-Entry Transfer Facility in accordance with the Book-Entry Transfer
Facility's procedure for such transfer. Although delivery of Shares may be
effected through book-entry transfer at the Book-Entry Transfer Facility, a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof), with any required signature guarantees, or an Agent's Message (as
defined herein), in connection with a book-entry transfer, and any other
required documents, must, in any case, be transmitted to, and received by, the
Depositary at one of its addresses set forth on the back cover of this Offer
to Purchase prior to the Expiration Date, or the tendering stockholder must
comply with the guaranteed delivery procedures described below. The
confirmation of a book-entry transfer of Shares into the Depositary's account
at the Book-Entry Transfer Facility as described above is referred to herein
as a "Book-Entry Confirmation." DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY
TRANSFER FACILITY IN ACCORDANCE WITH ITS BOOK-ENTRY PROCEDURES DOES NOT
CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
  The term "Agent's Message" means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of
the Book-Entry Confirmation, which states that the Book-Entry Transfer
Facility has received an express acknowledgment from the participant in the
Book-Entry Transfer Facility tendering the Shares that such participant has
received the Letter of Transmittal and agrees to be bound by the terms of the
Letter of Transmittal and that Purchaser may enforce such agreement against
such participant.
 
  THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE ELECTION AND SOLE RISK OF THE TENDERING
STOCKHOLDER AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED AT
THE DEPOSITARY. IF DELIVERY IS BY MAIL, THEN INSURED OR REGISTERED MAIL WITH
RETURN RECEIPT REQUESTED IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD
BE ALLOWED TO ENSURE TIMELY DELIVERY.
 
 SIGNATURE GUARANTEES
 
  No signature guarantee on the Letter of Transmittal is required if (i) the
Letter of Transmittal is signed by the registered holder of the Shares (which
term, for purposes of this Section, includes any participant in a Book-Entry
Transfer Facility system whose name appears on a security position listing as
the owner of the Shares) tendered therewith and such registered holder has not
completed either the box entitled "Special Delivery Instructions" or the box
entitled "Special Payment Instructions" on such Letter of Transmittal, or (ii)
such Shares are tendered for the account of a bank, broker, dealer, credit
union, savings association or other entity that is a member in good standing
of the Securities Transfer Agents Medallion Program, the New York Stock
 
                                       5
<PAGE>
 
Exchange Medallion Signature Guarantee Program or the Stock Exchange Medallion
Program (each, an "Eligible Institution"). In all other cases, all signatures
on the Letter of Transmittal must be guaranteed by an Eligible Institution.
See Instructions 1 and 5 to the Letter of Transmittal. If the Share
Certificates are registered in the name of a person other than the signer of
the Letter of Transmittal, or if payment is to be made to, or Share
Certificates not validly tendered or not accepted for payment or not purchased
are to be issued or returned to, a person other than the registered holder of
the Share Certificates, the tendered Share Certificates must be endorsed in
blank or accompanied by appropriate stock powers, signed exactly as the name
of the registered holder appears on the Share Certificates with the signature
on such Share Certificates or stock powers guaranteed by an Eligible
Institution. See Instructions 1 and 5 to the Letter of Transmittal.
 
 GUARANTEED DELIVERY
 
  If a stockholder desires to tender Shares pursuant to the Offer and such
stockholder's Share Certificates are not immediately available or the
procedures for book-entry transfer cannot be completed on a timely basis or
time will not permit all required documents to reach the Depositary prior to
the Expiration Date, such Shares may nevertheless be tendered provided that
all of the following guaranteed delivery procedures are duly complied with:
 
    (a) such tender is made by or through an Eligible Institution;
 
    (b) the Depositary receives (by hand, mail, telegram or facsimile
  transmission) on or prior to the Expiration Date, a properly completed and
  duly executed Notice of Guaranteed Delivery, substantially in the form
  provided by Purchaser; and
 
    (c) the Share Certificates representing all tendered Shares, in proper
  form for transfer (or Book-Entry Confirmation with respect to such Shares),
  together with a properly completed and duly executed Letter of Transmittal
  (or facsimile thereof) and any other documents required by the Letter of
  Transmittal, are received by the Depositary within three NYSE trading days
  after the date of such Notice of Guaranteed Delivery. An "NYSE trading day"
  is any day on which securities are traded on the NYSE.
 
  The Notice of Guaranteed Delivery may be delivered by hand, or may be
transmitted by telegram, facsimile transmission or mail, to the Depositary and
must include a guarantee by an Eligible Institution in the form set forth in
such Notice of Guaranteed Delivery.
 
  Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of (i) Share Certificates for (or a timely Book-
Entry Confirmation with respect to) such Shares, (ii) a properly completed and
duly executed Letter of Transmittal (or facsimile thereof), or, in the case of
book-entry transfer, an Agent's Message, and (iii) any other documents
required by the Letter of Transmittal. Accordingly, tendering stockholders may
be paid at different times depending upon when Share Certificates, Book-Entry
Confirmations and such other documents are actually received by the
Depositary. Under no circumstances will interest be paid by Purchaser on the
purchase price of the Shares to any tendering stockholders, regardless of any
extension of the Offer or any delay in making such payment.
 
 DETERMINATION OF VALIDITY
 
  All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of Shares will be determined
by Purchaser in its sole discretion, which determination will be final and
binding. Purchaser reserves the absolute right to reject any or all tenders of
any Shares that it determines are not in proper form or the acceptance for
payment of or payment for which may be unlawful. Purchaser also reserves the
absolute right to waive any of the conditions of the Offer or any defect or
irregularity in the tender of any Shares with respect to any particular
stockholder, whether or not similar defects or irregularities are waived in
the case of other stockholders. None of Purchaser, Parent, the Depositary, the
Information Agent or any other person will be under any duty to give notice of
any defects or irregularities in tenders or incur any liability for failure to
give any such notice. Purchaser's interpretation of the terms and conditions
of the Offer (including the Letter of Transmittal and the instructions
thereto) will be final and binding.

 OTHER REQUIREMENTS
 
  By executing the Letter of Transmittal as set forth herein, a tendering
stockholder irrevocably appoints designees of Purchaser as such stockholder's
proxies, each with full power of substitution, in the manner set forth in the
Letter of Transmittal, to the full extent of such stockholder's rights with
respect to the Shares tendered by such stockholder and accepted for payment by
Purchaser (and with respect to any and all other Shares or other securities or
rights issued or issuable in respect of such Shares on or after the Expiration
Date), effective when, if and to the extent that Purchaser accepts such Shares
for payment pursuant to the Offer. All such proxies shall be considered
coupled with an interest in the tendered Shares. Upon such acceptance for
payment, all prior proxies given by such stockholder with respect to such
Shares accepted for payment or other securities or rights will, without
further action, be revoked, and no subsequent proxies may be given. Such
designees of Purchaser will, with respect to such Shares for which the
appointment is effective, be empowered to exercise all voting and other rights
of such stockholder as they in their sole discretion may deem proper in
respect of any annual or special meeting of the Company's stockholders or any
adjournment or postponement thereof, by written consent in lieu of any such
meeting or otherwise. Purchaser reserves the right to require that, in order
for Shares to be deemed validly tendered, immediately upon Purchaser's payment
for such Shares, Purchaser must be able to exercise full voting rights with
respect to such Shares.
 
  Purchaser's acceptance for payment of Shares tendered pursuant to any of the
procedures described herein will constitute a binding agreement between the
tendering stockholder and Purchaser upon the terms and subject to the
conditions of the Offer.
 
 BACKUP FEDERAL INCOME TAX WITHHOLDING
 
  To prevent backup federal income tax withholding on payments of cash
pursuant to the Offer, a stockholder tendering Shares in the offer must
provide the Depositary with such stockholder's correct taxpayer identification
number ("TIN") on a Substitute Form W-9 and certify under penalties of perjury
that such TIN is correct and that such stockholder is not subject to backup
withholding. If a stockholder does not provide its correct TIN or fails to
provide the certification described herein, under federal income tax laws, the
Depositary will be required to withhold 31% of the amount of any payment made
to such stockholder pursuant to the Offer. All stockholders tendering Shares
pursuant to the Offer should complete and sign the Substitute Form W-9
included as a part of the Letter of Transmittal to provide the information and
certification necessary to avoid backup withholding. Noncorporate foreign
stockholders should complete and sign a Form W-8, Certificate of Foreign
Status, a copy of which may be obtained from the Depositary, in order to avoid
backup withholding. See Instruction 10 to the Letter of Transmittal.
 
3. WITHDRAWAL RIGHTS.
 
  Tenders of Shares made pursuant to the Offer will be irrevocable, except
that Shares tendered may be withdrawn at any time prior to the Expiration
Date, and, unless theretofore accepted for payment and paid for as provided
herein, may also be withdrawn at any time on or after January 2, 1999. If
Purchaser extends the Offer, is delayed in its acceptance for payment of
Shares or is unable to accept Shares for payment pursuant to the Offer for any
reason, then, without prejudice to Purchaser's rights under the Offer, the
Depositary may, nevertheless, on behalf of Purchaser, retain tendered Shares,
and such Shares may not be withdrawn except to the extent that tendering
stockholders are entitled to withdrawal rights as described in this Section.
Any such delay will be by an extension of the Offer to the extent required by
law. The reservation by Purchaser of the right to delay the acceptance or
purchase of or payment for Shares is subject to the provisions of Rule 14e-
1(c) under the Exchange Act, which requires Purchaser to pay the consideration
offered or to return Shares deposited by or on behalf of stockholders promptly
after the termination or withdrawal of the Offer.
 
  For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase.
Any notice of withdrawal must specify the name of the person who tendered the
Shares to be withdrawn, the number of Shares to be withdrawn and the name of
the registered holder of the Shares to be withdrawn as set forth on such Share
Certificates if different from the name of the person who tendered such
Shares. If Share
 
                                       7
<PAGE>
 
Certificates have been delivered or otherwise identified to the Depositary,
then, prior to the physical release of such Share Certificates, the serial
numbers shown on such Share Certificates must be furnished to the Depositary
and, unless such Shares have been tendered by an Eligible Institution, the
signatures on the notice of withdrawal must be guaranteed by an Eligible
Institution. If Shares have been delivered pursuant to the procedures for
book-entry transfer set forth in Section 2 above, any notice of withdrawal
must specify the name and number of the account at the appropriate Book-Entry
Transfer Facility to be credited with such withdrawn Shares and otherwise
comply with such Book-Entry Transfer Facility's procedures for withdrawal, in
which case a notice of withdrawal will be effective if delivered to the
Depositary by any method of delivery described in the first sentence of this
paragraph.
 
  All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by Purchaser in its sole discretion,
and its determination will be final and binding. No withdrawal of Shares will
be deemed to have been properly made until all defects and irregularities have
been cured or waved. None of Purchaser, the Dealer Manager, the Depositary,
the Information Agent or any other person will be obligated to give notice of
any defects or irregularities in any notice of withdrawal, nor shall any of
them incur any liability for failure to give any such notice.
 
  Withdrawals of tenders of Shares may not be rescinded, and any Shares
properly withdrawn will thereafter be deemed not validly tendered for purposes
of the Offer. However, withdrawn Shares may be retendered by following one of
the procedures described in Section 2 above at any time on or prior to the
Expiration Date.
 
4. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES.
 
  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any extension or
amendment), Purchaser will accept for payment, and will pay for all of the
Shares validly tendered on or prior to the Expiration Date and not properly
withdrawn in accordance with the procedures set forth in "THE TENDER OFFER--3.
Withdrawal Rights" promptly after the latest to occur of (i) the Expiration
Date, (ii) the expiration or termination of any applicable waiting periods
under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended (the
"HSR Act"), and (iii) the satisfaction or waiver of the other conditions to
the Offer set forth under "THE TENDER OFFER--19. Certain Conditions of the
Offer." Any determination concerning the satisfaction of the terms and
conditions of the Offer will be made by Purchaser in its good faith judgment
and such determination will be final and binding on all tendering
stockholders. Subject to applicable rules of the Commission and the terms and
conditions of the Merger Agreement, Purchaser expressly reserves the right, in
its sole discretion, to delay acceptance for payment of, or payment for,
Shares in order to comply in whole or in part with any applicable law or
governmental regulation.
 
  In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i)
the Share Certificates (or timely Book-Entry Confirmation of the book-entry
transfer of such Shares into the Depositary's account at a Book-Entry Transfer
Facility pursuant to the procedures set forth under Section 2 above), (ii) the
Letter of Transmittal (or facsimile thereof), properly completed and duly
executed, together with any required signature guarantees, or an Agent's
Message in connection with a book-entry transfer, and (iii) any other
documents required by the Letter of Transmittal.
 
  For purposes of the Offer, Purchaser will be deemed to have accepted for
payment, and thereby purchased, the Shares validly tendered to Purchaser and
not properly withdrawn as, if and when Purchaser gives oral or written notice
to the Depositary of Purchaser's acceptance for payment of such Shares
pursuant to the Offer. In all cases, upon the terms and subject to the
conditions of the Offer, payment for Shares so accepted for payment will be
made by the deposit of the purchase price therefor with the Depositary, which
will act as agent for tendering stockholders for the purpose of receiving
payment from Purchaser and transmitting payment to validly tendering
stockholders. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID BY PURCHASER ON THE
PURCHASE PRICE OF THE SHARES TENDERED PURSUANT TO THE OFFER, REGARDLESS OF ANY
EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT. Upon the deposit
of funds with the Depositary for the purpose of making payments to tendering
stockholders, Purchaser's obligation to make such payments shall be satisfied
and tendering stockholders must
 
                                       8
<PAGE>
 
thereafter look solely to the Depositary for payment of amounts owed to them
by reason of the acceptance for payment of Shares pursuant to the Offer.
Purchaser will pay any stock transfer taxes with respect to the transfer and
sale to it or its order pursuant to the Offer, except as otherwise provided in
Instruction 6 of the Letter of Transmittal, as well as any charges and
expenses of the Depositary and the Information Agent.
 
  If Purchaser is delayed in its acceptance for payment of, or payment for,
tendered Shares or is unable to accept for payment or pay for such Shares
pursuant to the Offer for any reason, then, without prejudice to Purchaser's
rights under the Offer (but subject to Purchaser's obligations under Rule 14e-
1(c) under the Exchange Act to pay for or return the tendered Shares promptly
after the termination or withdrawal of the Offer), the Depositary may,
nevertheless, retain tendered Shares on behalf of Purchaser, and such Shares
may not be withdrawn except to the extent tendering stockholders are entitled
to exercise, and duly exercise, withdrawal rights as described under "THE
TENDER OFFER--3. Withdrawal Rights."
 
  If any tendered Shares are not purchased pursuant to the Offer because of an
invalid tender or for any reason, Share Certificates for any such Shares will
be returned, without expense, to the tendering stockholder (or, in the case of
Shares delivered by book-entry transfer of such Shares into the Depositary's
account at a Book-Entry Transfer Facility pursuant to the procedures set forth
under Section 2 above, such Shares will be credited to an account maintained
at such Book-Entry Transfer Facility) as promptly as practicable following the
expiration or termination of the Offer.
 
  Purchaser reserves the right to transfer or assign, in whole or from time to
time in part, to one or more of Purchaser's subsidiaries or affiliates, the
right to purchase all or any Shares tendered pursuant to the Offer, but any
such transfer or assignment will not relieve Purchaser of its obligations
under the Offer or prejudice the rights of tendering stockholders to receive
payment for Shares validly tendered and accepted for purchase.
 
5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.
 
  The summary of Federal income tax consequences set forth below is for
general information only and is based on Purchaser's understanding of the law
as currently in effect. The tax consequences to each stockholder will depend
in part upon such stockholder's particular situation. Special tax consequences
not described herein may be applicable to particular classes of taxpayers,
such as financial institutions, broker-dealers, persons who are not citizens
or residents of the United States and stockholders who acquired their Shares
through the exercise of an employee stock option or otherwise as compensation.
ALL STOCKHOLDERS SHOULD CONSULT WITH THEIR OWN TAX ADVISORS AS TO THE
PARTICULAR TAX CONSEQUENCES OF THE OFFER AND THE MERGER TO THEM, INCLUDING THE
APPLICABILITY AND EFFECT OF THE ALTERNATIVE MINIMUM TAX AND ANY STATE, LOCAL
OR FOREIGN INCOME AND OTHER TAX LAWS AND OF CHANGES IN SUCH TAX LAWS.
 
  The receipt of cash for Shares tendered pursuant to the Offer (or the
Merger) will be a taxable transaction for federal income tax purposes and may
also be a taxable transaction under applicable state, local or foreign tax
laws. Generally, for federal income tax purposes, a stockholder who receives
cash for Shares pursuant to the Offer (or the Merger) will recognize gain or
loss equal to the difference between the amount of cash received in exchange
for the Shares sold and such stockholder's adjusted tax basis in such Shares.
Provided that the Shares constitute capital assets in the hands of the
stockholder, such gain or loss will be capital gain or loss, and will be long
term capital gain or loss if the holder has held the Shares for more than one
year at the time of sale. Gain or loss will be calculated separately for each
block of Shares (i.e., a group of Shares with the same tax basis and holding
period) tendered pursuant to the Offer. The maximum federal income tax rate
applicable to non-corporate taxpayers on long-term capital gains is generally
20% for transactions after 1997.
 
  A stockholder (other than certain exempt stockholders including, among
others, all corporations and certain foreign individuals and entities) who
tenders Shares may be subject to 31% backup withholding unless the stockholder
provides its TIN and certifies that such number is correct or properly
certifies that it is awaiting a TIN, or unless an exemption applies. A
stockholder who does not furnish its TIN may be subject to a penalty imposed
by the Internal Revenue Service (the "IRS"). See "THE TENDER OFFER--3.
Procedure for Accepting the Offer and Tendering Shares."
 
                                       9
<PAGE>
 
  If backup withholding applies to a stockholder, the Depositary is required
to withhold 31% from payments to such stockholder. Backup withholding is not
an additional tax. Rather, the amount of the backup withholding can be
credited against the federal income tax liability of the person subject to the
backup withholding, provided that the required information is given to the
IRS. If backup withholding results in an overpayment of tax, a refund can be
obtained by the stockholder upon filing an appropriate income tax return.

  Parent, IT Corporation, a wholly-owned subsidiary of Parent ("IT"), certain
other direct and indirect subsidiaries of Parent (including Purchaser) are
party to a credit agreement dated as of February 25, 1998, as amended and
restated as of June 11, 1998 (as amended to date, the "Credit Facility"), with
Citicorp USA, Inc. ("Citicorp" and, in its capacity as administrative agent,
the "Administrative Agent") and BankBoston, N.A. ("BankBoston" and, in its
capacity as agent, together with the Administrative Agent, the "Agents"),
individually and as agent banks for a group of lenders, and those lenders,
that provides for a term loan and revolving credit facilities of up to $413
million in the aggregate. The Credit Facility consists of an eight-year
amortizing term loan of $228 million and a six-year revolving credit facility
of up to $185 million.
 
  The proceeds of revolving credit loans made to Parent (or a subsidiary of
Parent) under the Credit Facility will be used to finance the Offer and the
Merger. Approximately $51.0 million of proceeds from the revolving loans and
from Parent's cash on hand will be made available to Purchaser. These funds,
together with the Company's cash on hand (a portion of which will be loaned to
Purchaser), will be used by Purchaser to pay for Shares accepted for payment
in the Offer and to pay cash consideration in the Merger. Existing cash and
the proceeds of revolving credit loans will be used to pay certain expenses
and costs related to the Offer and the Merger. The proceeds of revolving loans
made under the Credit Facility also will be used to provide working capital
for Parent and its subsidiaries (including, after the Merger, the Company and
its subsidiaries) and for general corporate purposes of Parent and its
subsidiaries.
 
  The availability of financing under the Credit Facility is subject to the
following conditions: (i) no default, (ii) continued accuracy of
representations and warranties, (iii) no material adverse change with respect
to Parent or certain of its principal operating subsidiaries and (iv) certain
other conditions customary for credit facilities of this type.
 
  The Credit Facility also requires that, with respect to the Offer and the
Merger, (i) revolving credit availability under the Credit Facility shall be
at least equal to $25 million plus the amount necessary to complete the Merger
on the date of the purchase of Shares pursuant to the Offer, (ii) average
revolving credit availability under the Credit Facility after subtracting the
amount of revolving loans made to finance the purchase of Shares in the Offer,
shall not be less than $25 million for the 60 days prior to the date of such
purchase, (iii) the Company have at least $15 million of cash and marketable
securities on the date of purchase of Shares pursuant to the Offer, and that,
not later than the time of completion of the Merger, such cash be used to
purchase Shares accepted for payment in the Offer or to complete the Merger or
be applied to repay revolving loans under the Credit Facility, (iv) the Board
shall have recommended that stockholders tender their Shares in the Offer, (v)
the Merger be completed no later than February 15, 1999, and that all
conditions to the Merger contained in the Merger Agreement are satisfied or
waived with the consent of the lenders, and (vi) the Merger Agreement shall
not be amended, waived or modified in any material respect without approval of
the Agents and the lenders.
 
  The Credit Facility is secured by a security interest in substantially all
of the assets of Parent and its subsidiaries (including the Shares acquired by
Purchaser upon completion of the Offer and the assets of the Company and its
subsidiaries).
 
  Parent expects that the Credit Facilities will provide sufficient
availability to finance the Offer and the Merger and related costs and
expenses and to provide for Parent's and its subsidiaries' (including the
Company's) ongoing working capital needs.
 
  The term loans made under the Credit Facility bear interest at a rate equal
to LIBOR plus 2.50% per annum (or Citibank's base rate plus 1.50% per annum)
and revolving loans made under the Credit Facility bear interest at a rate
equal to LIBOR plus 2.00% per annum (or Citibank's base rate plus 1.00% per
annum) through no later than 30 days from the end of Parent's fiscal quarter
ending December 25, 1998, with certain exceptions to be determined as of the
date of Parent's filing a compliance certificate regarding its financial
position in accordance with the Credit Facility, with adjustments thereafter
based on the ratio of Parent's consolidated total debt to consolidated EBITDA.
A commitment fee will accrue on the portion of the revolving credit facility
that is unused from time to time at a rate initially equal to 0.375% per
annum, subject to adjustment based on the ratio of
 
                                      15
<PAGE>
 
Parent's consolidated total debt to consolidated EBITDA. As of October 29,
1998, based on the prevailing one-month LIBOR rate of 5.22%, the interest rate
applicable to revolving loans under the Credit Facility is estimated to be
approximately 7.22%.
 
  The term loan made under the Credit Facility amortizes on a semi-annual
basis in aggregate annual installments of $4.5 million for the first six years
after June 1998, with the remainder payable in eight equal quarterly
installments in the seventh and eighth years thereafter. Parent will also be
required to prepay the loans under the Credit Facility with the net proceeds
of asset sales and certain debt and equity financings, and loans under the
Credit Facility will be required to be prepaid with a portion of Parent's
consolidated excess cash flow.
 
  The Credit Facility includes certain representations and warranties and
covenants customary for facilities of this type, including: (i) financial
covenants consisting of a minimum fixed charge coverage ratio, a minimum
interest expense coverage ratio, a maximum leverage ratio, a minimum liquidity
requirement, a minimum EBITDA requirement (applicable only in 1998), a maximum
capital expenditure limitation and a minimum net worth requirement; (ii)
maintenance of cash concentration accounts and lockboxes, (iii) preservation
of corporate existence, compliance with laws, payment of taxes, maintenance of
properties and insurance and financial and other reporting requirements; and
(iv) limitations (subject to certain exceptions) on indebtedness, guarantees,
liens, lease obligations, mergers and acquisitions, sales of assets and other
fundamental changes, joint ventures and other investments, transactions with
affiliates, dividends and stock repurchases and redemptions, prepayment or
modification of debt, and certain hedging obligations. The Credit Facility
also includes customary events of default, including payment defaults,
breaches of representations and warranties, covenant defaults, cross defaults
to other indebtedness, bankruptcy events, defaults in satisfaction of money
judgments, material adverse change, certain events under the Employee
Retirement Income Security Act of 1974, as amended, a change of control of the
Parent.
 
  Purchaser's obligation to purchase Shares tendered pursuant to the Offer is
not subject to financing.
 
10. CERTAIN TRANSACTIONS AMONG PARENT, THE COMPANY AND THEIR RESPECTIVE
AFFILIATES.
 
  Certain affiliates of Parent and FD have entered into, or proposed to
perform, a number of contracts in the ordinary course of business. IT is a
subcontractor to Fluor Daniel Fernald, Inc. ("FDF"), a wholly-owned subsidiary
of FD. Pursuant to the multi-year subcontract, which was awarded in September
1997, IT anticipates performing in excess of $120 million in remediation
services in connection with remediation of the United States Department of
Energy's Fernald Environmental Management Project. IT is in negotiation with
FDF with respect to additional compensation or work resulting from changed
conditions at the site. Also with respect to the Fernald facility, IT has been
awarded an additional subcontract to perform approximately $305,000 in
stabilization testing regarding certain wastes at the facility. In September
1998, IT submitted a competitive bid (but to date has not been awarded a
contract) to perform, as a subcontractor to FDF, certain accelerated waste
retrieval services at the project, which FDF has publicly estimated to involve
between $25 million and $35 million of work. In October 1998 IT submitted a
competitive bid (but to date has not been awarded a contract) to perform, as a
subcontractor to FDF, additional waste removal, stabilization, and disposal
services  at the project, which FDF has publicly estimated to involve between
$20 million and $25 million of work. In addition, in October 1997, FDF awarded
OHM Remediation Services Corp. ("OHMRSC"), an indirect wholly-owned subsidiary
of Parent, a subcontract to perform approximately $250,000 in engineering
studies at the facility. FDF has an option, which is exercisable until March
1999, to order from OHMRSC approximately $529,000 in remediation services with
respect to previously-studied thorium wastes.
 
  In connection with the Merger and the Offer, the Company and FD have entered
into the Amended and Restated Marketing Agreement, dated as of October 27,
1998, among the Company, FD and Parent (the "Amended Marketing Agreement"),
described in "THE TENDER OFFER--14. The Merger Agreement and Related
Agreements."

11. CONTACTS WITH THE COMPANY; BACKGROUND OF THE OFFER AND THE MERGER.
 
 Background of the Transaction: Past Contracts, Transactions and Negotiations
with Parent and Purchaser
 
  In June, 1998, Parent was informally contacted by BT Alex. Brown regarding
Parent's possible interest in a transaction with the Company. At that time,
Parent did not express a preliminary interest in an acquisition.
However, in late July 1998, Parent was again approached by BT Alex. Brown, the
Company and Parent entered into the Confidentiality Agreement dated July 28,
1998 and Parent was provided with non-public information about the Company.
During August 1998, Parent conducted a due diligence review of the Company and
met with Mr. Walter C. Barber, President and Chief Executive Officer of the
Company, and other members of the Company's senior management to discuss the
desirability of combining operations and general approaches to a potential
acquisition, to exchange non-public information and to review likely synergies
that could be created in a combination.
 
  On September 9, 1998, following authorization by the Board of Directors of
Parent, Parent submitted a non-binding letter of interest outlining a proposed
acquisition of the Company (the "September 9 Proposal"). In the September 9
Proposal, Parent proposed to acquire all of the issued and outstanding Shares
for aggregate cash in the range of $65 to $70 million. The September 9
Proposal contemplated a tender offer to the stockholders, which would be
conditioned on the ability of Parent to acquire in excess of 50% of the Shares
in the proposed tender offer, the continuation of the existing marketing
agreement between FD and the Company and agreement on specific due diligence
issues in addition to other customary conditions to be contained in a
definitive merger agreement. The September 9 Proposal was also subject to
Parent's completing a due diligence review of the Company.
 
  In a telephone conversation with BT Alex. Brown on September 11, 1998,
Philip O. Strawbridge, Senior Vice President and Chief Administrative Officer
of Parent, indicated a price of $8.00 per Share in the proposed tender offer
and Parent's willingness to consider increasing the price to $8.50 per Share
if FD would finance a portion of the transaction. They also discussed the
possibility of Parent making payments to FD in exchange for certain revenue
commitments in a new marketing agreement.
 
  Following the meetings of the Board on September 10 and 11, 1998, there were
several telephone conversations between BT Alex. Brown and Mr. Strawbridge
regarding terms of a possible transaction and one telephone conversation
between management of FD and Parent regarding a possible new marketing
agreement. As a result of these conversations, Parent submitted a revised non-
binding letter of interest outlining a proposed acquisition of the Company
(the "September 16 Proposal"). In the September 16 Proposal, Parent proposed
to acquire all of the issued and outstanding Shares for $8.50 per Share in
cash in a tender offer to the stockholders. The September 16 Proposal was
expressly conditioned on the ability of Parent to acquire in excess of 50% of
the Shares, the Company having available at least $19 to $20 million in cash,
the making by FD of a $20 million subordinated loan to Parent to be used in
financing the acquisition, FD and the Company entering into a new, five-year
marketing agreement that would generate certain levels of annual revenues to
the Company and Parent, and for which FD would receive annual payments
totaling $3.0 million, and other conditions to be contained in a definitive
merger agreement. The September 16 Proposal was also subject to Parent's
completing a due diligence review of the Company.
 
  On September 18, 1998 legal counsel for Parent distributed a proposed draft
merger agreement to the Company, FD and BT Alex Brown.
 
  On September 22, 1998, the Board met to consider Parent's September 16
Proposal. At that meeting, it was decided to proceed with further negotiations
and the Special Committee was established. Parent's legal counsel and legal
counsel for the Special Committee began negotiations regarding the draft
merger agreement.
 
  Between September 22, 1998 and October 5, 1998, representatives of FD and
Parent, along with BT Alex. Brown, discussed the possible terms of a loan from
FD to Parent and a possible new marketing agreement between FD and the Company
following the proposed acquisition. On October 4, 5 and 6, 1998, Mr. David
 
                                      17
<PAGE>
 
Myers, Group President--Industrial of FD and a director of the Company, and
Mr. Strawbridge discussed the loan and the new marketing agreement requested
by Parent in its September 16 Proposal. Mr. Strawbridge indicated that, if no
loan from FD was possible and the new marketing agreement did not include
revenue commitments, Parent would lower the price set forth in the September
16 Proposal to $8.25 per Share and would not pay FD annual payments in
connection with the new marketing agreement. During this period, legal counsel
for the Special Committee negotiated terms of the proposed merger agreement
with FD and legal counsel for Parent, including the Minimum Condition,
approval of changes to the Offer after a definitive merger agreement was
executed by the parties and several other provisions.
 
  At a regularly scheduled meeting of the Board of Directors of Parent held on
October 6, 1998, members of management of Parent made a comprehensive
presentation regarding the Company, its operations, financial condition and
competitive position, as well as the potential synergies that could be
realized from a combination between the Company and Parent and the benefits to
be derived from the proposed new marketing agreement. Parent's Board of
Directors also discussed the terms of and the financing for the transaction,
including the availability of cash at the Company and the alternatives
available to Parent in light of FD's decision not to provide the loan
requested in Parent's proposal. Management updated the Board of Directors of
Parent on the progress of negotiations with Parent's lenders regarding
amendments to the Credit Facility that would be required in order to
consummate the transaction. Following a full discussion of the proposed
transaction, it was the consensus of Parent's Board of Directors that Parent
should proceed with the acquisition of the Company. Final approval of the
acquisition of the Company and the terms and adequacy of the financing for the
acquisition was delegated to the Executive Committee of Parent's Board of
Directors.
 
  On October 13, 1998 the Executive Committee of Parent's Board of Directors
held a telephonic meeting at which they reviewed financial and operating data
for the Company, the final terms of the proposed acquisition of the Company
and the arrangements for financing the acquisition with borrowings under the
Credit Facility and available cash at the Company. After discussion and
pursuant to the authority delegated to the Executive Committee at the October
6, 1998 meeting of Parent's Board of Directors, the Executive Committee
approved the transaction and directed management to complete negotiation of
the definitive merger agreement as soon as practicable.
 
  Parent's legal counsel and legal counsel for the Special Committee continued
to negotiate the proposed draft merger agreement and FD and Parent continued
to negotiate the proposed marketing agreement through October 27, 1998. The
changes finally agreed upon in respect of the Merger Agreement included:
(i) imposing as a condition to the Offer the Minimum Condition, which requires
a majority of the Shares not held by FD to be tendered, (ii) reducing the fees
payable by the Company to Parent on certain terminations of the Merger
Agreement from $2.5 million to $1.5 million (plus reimbursement of expenses of
up to $400,000); (iii) requiring the approval of the Special Committee for
certain changes to or conditions of the Offer; and (iv) eliminating a
provision prohibiting the Company from entering into an agreement with a third
party that was more favorable to the stockholders unless it first provided
Parent the opportunity to make an offer at least as favorable as such third
party offer. As agreed between Parent and FD, no annual payments are to be
made by Parent to FD and no revenue commitments are made by FD under the final
Amended Marketing Agreement.
 
  On October 26, 1998, Parent advised the Company that it had received the
necessary consent from its lenders to enter into the Merger Agreement and
consummate the Offer, and that it had completed its selective due diligence.
Parent further advised the Company that it was prepared to immediately
commence and diligently complete all regulatory and governmental filings
necessary to effectuate a transaction and was prepared to execute the Merger
Agreement and Amended Marketing Agreement.
 
  On the afternoon of October 27, 1998, the Special Committee and the full
Board held a special telephonic meeting with legal counsel to the Special
Committee, legal counsel to FD and representatives of BT Alex. Brown
participating, and discussed a revised proposal from a third party (the "Third
Party Proposal") and the status of negotiations with Parent regarding the
proposed transaction, including the Amended Marketing Agreement. Legal counsel
to the Special Committee reviewed the Third Party Proposal and the terms of
the Merger
 
                                      18
<PAGE>
 
Agreement. Legal counsel to FD reviewed the terms of the proposed Amended
Marketing Agreement. BT Alex. Brown then presented a review of its financial
analysis of the proposed tender offer of $8.25 per Share for all Shares and
then presented its opinion to the Special Committee and the full Board that
the consideration to be received in the proposed transaction was fair from a
financial point of view to the stockholders, other than FD, Parent or any
affiliate either thereof (the "Public Stockholders"). At the conclusion of the
presentation by BT Alex. Brown, the FD representatives on the Board informed 
the Special Committee that, other than the Amended Marketing Agreement, there 
were no agreements or understandings between FD and Parent other than existing
contractual arrangements in the ordinary course of business.
 
  The Special Committee then held a separate meeting without representatives
of FD present, reviewed the Third Party Proposal and determined it was not in
the best interests of the stockholders to delay entering into the Merger
Agreement with Parent given, among other things, the conditions that proposal
contained regarding financing, the proposed schedule of due diligence and the
need to negotiate a definitive agreement. Legal counsel to the Special
Committee discussed the Committee's fiduciary duties in reviewing and
approving the proposed transaction with Parent. The Special Committee
determined that, based on the opinion of BT Alex. Brown as to the fairness of
the consideration from a financial point of view to the Public Stockholders
and all other relevant factors in relation to the proposed transaction with
Parent, it would recommend that the full Board of Directors approve the
transaction as in the best interests of the Company and the stockholders.
 
  After the separate meeting of the Special Committee, the full Board
continued its meeting. The Special Committee discussed with the Board its
review of the terms and conditions of the proposed transaction with Parent and
the Third Party Proposal. At the conclusion of those discussions and upon the
unanimous recommendation of the Special Committee, the Board of Directors
unanimously voted to approve the Merger Agreement and the Amended Marketing
Agreement and to terminate discussions with the third party (as required by
the Merger Agreement).
 
  Following the Board meeting, the Special Committee's legal counsel and
Parent's legal counsel continued the final negotiation of the transaction
documents. The Merger Agreement and Amended Marketing Agreement were executed
in the evening of October 27, 1998, and press releases were issued by the
parties announcing the execution of the Merger Agreement on the morning of
October 28, 1998.
 
12. PURPOSE OF THE OFFER AND THE MERGER.
 
  The purpose of the Offer is for Purchaser to acquire all of the Shares. The
purpose of the Merger is for Parent to acquire the remaining equity interest
in the Company not acquired pursuant to the Offer. Upon consummation of the
Merger, the Company will become a direct, wholly-owned subsidiary of Parent.
The acquisition of Shares has been structured as a cash tender offer followed
by a cash merger in order to provide for the prompt and orderly cancellation
of all Shares (other than Excluded Shares) and the transfer of ownership of
the equity interest in the Company held by the Company's stockholders (other
than the Excluded Shares) from such stockholders to Parent.
 
  Under the DGCL, the approval of the Board and the affirmative vote of the
holders of a majority of the Shares may be required to approve and adopt the
Merger Agreement and the transactions contemplated thereby, including the
Merger. If a vote of the stockholders of the Company is required, the Company
has agreed in the Merger Agreement to take all action necessary to convene a
special meeting of its stockholders (the "Stockholders Meeting") as promptly
as practicable after the consummation of the Offer for the purpose of
considering and taking action on the Merger Agreement and the transactions
contemplated thereby. The Proxy Statement containing detailed information
concerning the Merger will be furnished to stockholders of the Company in
connection with any Stockholders Meeting. Notwithstanding the foregoing, if
Parent, Purchaser and/or any other subsidiary of Parent shall acquire at least
90% of the Shares, the parties shall take all necessary and appropriate action
to cause the Merger to become effective as soon as practicable after
consummation of the Offer without a Stockholders Meeting in accordance with
Section 253 of the DGCL.
 
 
                                      19
<PAGE>
 
  The Board, acting on the unanimous recommendation of the Special Committee,
has unanimously determined that the transactions contemplated by the Merger
Agreement are fair to, and in the best interests of the Company stockholders,
and have approved and adopted the Merger Agreement and the transactions
contemplated thereby. As described above, the only remaining corporate action
of the Company that may be required is the approval and adoption of the Merger
Agreement and the transactions contemplated thereby by the holders of a
majority of the Shares. If Purchaser acquires the Minimum Share Number, it
will have sufficient voting power to cause the approval and adoption of the
Merger Agreement and the transactions contemplated thereby without the
affirmative vote of any other stockholder of the Company. If Purchaser
acquires at least 90% of the Shares in the Offer, under Delaware law it will
be able to consummate the Merger without a vote of the Company's stockholders.
Purchaser reserves the right to purchase additional Shares in the open market
after termination of the Offer.
 
  Pursuant to the Merger Agreement, FD has agreed, among other things, to
tender in, and not withdraw from, the Offer, all Shares (including the FD
Shares representing approximately 52.3% of the Shares) owned by it or any of
its affiliates.
 
13. PLANS FOR THE COMPANY.
 
  It is anticipated that, following the consummation of the Offer, the
Company's business will be integrated into Parent's operations. Parent plans
to reorganize the Company into Parent's existing business line/project
delivery organizational structure, which is expected to produce administrative
and operational efficiencies and to result in the elimination of redundant
positions in the combined organization and the closure or consolidation of
certain Parent and Company locations. Pursuant to the Merger Agreement,
immediately following the delivery to the Depositary of Parent's notice of
acceptance of Shares pursuant to the Offer (the "Notice of Acceptance"), if
the Minimum Condition has been met, Parent shall be entitled to designate four
of the six authorized directors on the Board (the "Parent Directors"). The
Parent Directors shall be Anthony J. DeLuca, Philip O. Strawbridge, James G.
Kirk and James R. Mahoney. Immediately following delivery to the Depositary of
the Notice of Acceptance, the resignations as directors of the Company of
Walter C. Barber, David L. Myers and Ronald G. Peterson, delivered to Parent
in connection with the execution and delivery of the Merger Agreement, shall
be deemed effective and Allan S. Bufferd and Ernie Green, as the remaining
directors of the Company (the "Continuing Directors"), shall execute and
deliver a written consent or shall otherwise take effective action electing
the Parent Directors to the Board. The Continuing Directors shall remain
members of such Board until the Effective Time, and, in lieu of Continuing
Directors, if such directors will not serve, the Company shall use reasonable
efforts to ensure that the Board shall consist of at least two members who are
neither officers, stockholders, designees nor affiliates of Parent or FD or
their respective affiliates (the "Special Directors"). Therefore, Parent will
be entitled to designate a majority of the Board and will control the Company,
subject to certain limitations set forth in the Merger Agreement. Except for
the Merger and as otherwise described in this section and elsewhere herein,
Purchaser and Parent have no current plans or proposals that would result in
an extraordinary corporate transaction, such as a merger, reorganization, or
consolidation of the Surviving Corporation with or into any third entity, the
sale or transfer of substantially all of the Surviving Corporation's assets to
a third party, a material change in the Company's capitalization or dividend
structure or any other material changes in the Surviving Corporation's
corporate structure or business to reorganize the Company. Following the
consummation of the Offer, Parent intends to continue its evaluation and
review the Surviving Corporation's operations and the potential opportunities
for synergies with Parent's operations, and consideration of what, if any,
additional changes would be desirable in light of the results of such
evaluations and reviews.
 
14. THE MERGER AGREEMENT AND RELATED AGREEMENTS.
 
  The following summary of certain provisions of the Merger Agreement is
presented only as a summary and is qualified in its entirety by reference to
the Merger Agreement, a copy of which is filed as an exhibit to Parent's
Schedule 14D-1.
 
  The Offer. The Merger Agreement provides for the making of the Offer.
Pursuant to the Offer, each tendering stockholder shall receive the Offer
Price for each share tendered in the Offer. Purchaser's obligation to
 
                                      20
<PAGE>
 
accept for payment or pay for Shares is subject to the satisfaction of the
conditions that are described in "THE TENDER OFFER--19. Certain Conditions of
the Offer." Any determination concerning the satisfaction of the terms and
conditions of the Offer will be made by Purchaser in its good faith judgment
and such determination will be final and binding on all tendering
stockholders. Parent expressly reserves the right to increase the price per
Share payable in the Offer (although it has no present intention of doing so)
or to make any other changes in the terms and conditions of the Offer, except
that, pursuant to the Merger Agreement, unless previously approved by the
Special Committee and the Board in writing, Parent may not (i) decrease the
Offer Price, (ii) change the form of consideration payable in the Offer, (iii)
reduce the maximum number of Shares to be purchased in the Offer, (iv) amend
the conditions to the Offer set forth in "THE TENDER OFFER--19. Certain
Conditions of the Offer" to broaden their scope, (v) impose additional
conditions of the Offer or amend any other term of the Offer in any manner
adverse to holders of Shares or extend the Offer if all of the conditions to
the Offer are satisfied or waived, or (vi) amend the Minimum Condition.
 
  Notwithstanding the foregoing, Parent expressly reserves the right, in its
sole discretion (but subject to the terms and conditions of the Merger
Agreement), at any time and from time to time, without the consent of the
Special Committee or the Board, to (i) from time to time extend the Offer
(each such individual extension not to exceed 10 business days after the
previously scheduled Expiration Date), if at the scheduled Expiration Date of
the Offer any of the conditions to the Offer shall not have been satisfied or
waived, until such time as such conditions are satisfied or waived; (ii)
extend the Offer for any period required by any rule, regulation,
interpretation or position of the Commission or the staff thereof applicable
to the Offer; or (iii) extend the Offer for any reason on up to two (2)
occasions in each case for a period of not more than five (5) business days
beyond the latest Expiration Date that would otherwise be permitted under
clause (i) or (ii) of this sentence if on such Expiration Date there shall
have been tendered more than the number of Shares sufficient to satisfy the
Minimum Condition but less than 90% of the Shares, provided the Purchaser
agrees to permanently waive the conditions set forth in paragraphs (b) and (e)
of "THE TENDER OFFER--19. Certain Conditions of the Offer." If all of the
conditions to the Offer set forth in "THE TENDER OFFER--19. Certain Conditions
of the Offer" are not satisfied on any scheduled Expiration Date of the Offer
then, provided that all such conditions are reasonably capable of being
satisfied prior to December 31, 1998, Parent shall extend the Offer from time
to time (each such individual extension not to exceed 10 business days after
the previously scheduled Expiration Date) until such conditions are satisfied
or waived, provided that Parent shall not be required to extend the Offer
beyond December 31, 1998.
 
  Board Representation. Pursuant to the Merger Agreement, immediately
following the delivery of the Notice of Acceptance, if the Minimum Condition
has been met, Parent shall be entitled to designate the Parent Directors as
described above in above section entitled "THE TENDER OFFER--13. Plans for the
Company." Immediately following the election of the Parent Directors, the
Company will use its reasonable efforts to cause persons designated by Parent
to constitute the same percentage as the Parent Directors represent on the
Board of (i) each committee of such Board (other than any committee of such
Board established to take action under the Merger Agreement), (ii) each board
of directors of each subsidiary of the Company and (iii) each committee of
each such board. The Company's obligations to appoint designees of Parent to
the Board shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder.
 
  The Merger. As soon as practicable after the satisfaction or waiver of the
conditions to the Merger, Purchaser or another direct or indirect wholly-owned
subsidiary of Parent will be merged with and into the Company, the separate
corporate existence of Purchaser or of such other subsidiary of Parent, as the
case may be, will cease and the Company will continue as the Surviving
Corporation. The Effective Time will occur at the date and time that a
certificate of merger, in such form as is required by, and executed in
accordance with, the relevant provisions of the DGCL (the "Certificate of
Merger"), is filed with the Secretary of State of the State of Delaware. The
Surviving Corporation shall continue its corporate existence under the laws of
the State of Delaware. The Certificate of Incorporation of the Company in
effect at the Effective Time will be the Certificate of Incorporation of the
Surviving Corporation until duly amended in accordance with the terms thereof
and the DGCL, except that the Article FOURTH of the Certificate of
Incorporation shall be amended such that the Surviving Corporation shall have
the authority to issue 1,000 shares of its common stock, par value $.01 per
 
                                      21
<PAGE>
 
share. The Bylaws of the Company in effect at the Effective Time shall be the
Bylaws of the Surviving Corporation. The directors of Purchaser at the
Effective Time will be the directors of the Surviving Corporation until their
successors are duly elected and qualified, and the officers of the Company at
the Effective Time will be the officers of the Surviving Corporation until
replaced in accordance with the Bylaws of the Surviving Corporation. It is
expected that, immediately following the Effective Time, the Board of
Directors of the Surviving Corporation will appoint Anthony J. DeLuca, Philip
O. Strawbridge, James R. Mahoney and James G. Kirk as the President, Executive
Vice President, Senior Vice President and Senior Vice President and Secretary
of the Surviving Corporation, respectively.
 
  Parent Stock Option. Pursuant to the Merger Agreement, after Purchaser has
accepted for payment Shares tendered pursuant to the Offer (including the
Minimum Share Number), Parent has the irrevocable option (the "Parent Option")
to purchase that number of authorized and unissued shares of the Company's
Common Stock equal to 14% of the Shares outstanding immediately after the
exercise of the Parent Option (the "Option Shares") at a purchase price equal
to the Offer Price. The Company's sole obligation to issue and deliver the
Option Shares is subject to certain conditions set forth in the Merger
Agreement, including the requirement that the number of Option Shares plus the
number of Shares accepted for payment pursuant to the Offer, upon issuance of
the Option Shares, will constitute at least 90% of then outstanding Shares.
 
  Use of Company Cash. Pursuant to the Merger Agreement, the Company has
agreed that prior to the initial Expiration Date it will take all steps
reasonably necessary, after consulting with Parent, to sell any marketable
securities owned by it so that on the initial Expiration Date the Company will
have maximized its available cash and will thereafter until such time as the
Parent Directors are elected invest such cash in overnight investments. Upon
the election of the Parent Directors and at the direction of the Company's
Board, up to $20 million of the available cash of the Company will be loaned
to Parent and evidenced by an interest bearing promissory note payable on
demand. The proceeds of such loan will be delivered to the Depositary to be
used solely to fund the purchase of Shares in the Offer.
 
  Consideration to Be Paid in the Merger. At the Effective Time, each issued
and outstanding Share (other than Excluded Shares), shall be converted into,
and become exchangeable for the Offer Price.
 
  Employee/Director Stock Options. Pursuant to the Merger Agreement, at the
Effective Time, all options to purchase a share of Common Stock (whether
vested or unvested) (each a "Company Option") granted under the Company's
Amended and Restated 1987 Stock Plan, the Company's 1997 Stock Plan and the
Company's Amended and Restated 1995 Director Stock Option Plan, in each case
as amended to the date hereof (the "Stock Plans") that have an exercise price
that is lower than the Offer Price (the "In-the Money Options") will be cashed
out by the Company by payment to each holder of such In-the-Money Options the
difference between the exercise price and the Offer Price. In accordance with
the terms of the Stock Plans or interpretations thereof by the Board, the
Company will notify all holders of Company Options that have an exercise price
that is equal to or higher than the Offer Price (the "Underwater Options"),
promptly after the Effective Time, that the Stock Plans have been terminated
and that, in connection with such termination, the Company will pay to such
holders an amount equal to the number of such Underwater Options (whether vest
or unvested) multiplied by $.10. Pursuant to the provisions of the Merger
Agreement, the Company will make aggregate payments equal to approximately
$116,388. Of that total, Mr. Barber will receive approximately $19,472; Mr.
Glenn V. Batchelder will receive approximately $6,508; Mr. J. Steve Paquette
will receive approximately $5,125; Mr. David L. Backus will receive
approximately $500; Ms. Anne Nolan will receive approximately $2,019; and Ms.
Mary C. Stack will receive approximately $479. The Company will make aggregate
payments to non-employee directors in the amount of $2,119. Of that total,
Mr. Allan S. Bufferd will receive approximately $1,221 and Mr. Ernie Green
will receive approximately $898.
 
  The Board will take the following actions with respect to the Amended and
Restated 1986 Employee Stock Purchase Plan (the "Stock Purchase Plan"): (1)
accelerate the current Payment Period (as defined in the Stock Purchase Plan)
to November 27, 1998 (the "Acceleration Date") and (2) pay each participant in
lieu of each share that could have been purchased under the Stock Purchase
Plan when the Payment Period ends on the
 
                                      22
<PAGE>
 
Acceleration Date, an amount (subject to any applicable withholding tax) in
cash equal to the difference between the Offer Price and the Option Price (as
defined in the Stock Purchase Plan). Pursuant to the provisions of the Merger
Agreement, the Company will make aggregate payments equal to approximately
$91,126. Of that total, Mr. Barber will receive approximately $1,005;
Mr. Batchelder, Mr. Paquette and Ms. Nolan will each receive $0; Mr. Backus
will receive approximately $3,145; and Ms. Stack will receive approximately
$1,933. In addition, all funds contributed to the Stock Purchase Plan which
have not been used to purchase shares of the Common Stock as of the
Acceleration Date will be returned, in cash, without interest, to participants
of the Stock Purchase Plan as soon as administratively feasible after the
Acceleration Date.
 
  Representations and Warranties. The Merger Agreement contains various
representations and warranties of the parties thereto. These include
representations and warranties of the Company, Purchaser and Parent with
respect to corporate existence and power, capitalization, subsidiaries,
corporate authorization relative to the Merger Agreement, governmental
consents and approvals, Commission reports, financial statements, absence of
certain changes or events, litigation and liabilities, employee benefits,
compliance with laws, environmental laws, intellectual property, taxes,
government contracts, documents relating to the Offer and the Merger and other
matters. No representations or warranties made by the Company, Parent or
Purchaser will survive beyond the Effective Time, and no covenants or
agreements made in the Merger Agreement will survive beyond the Effective
Time, except for those covenants or agreements which by their terms
contemplate performance after the Effective Time. Certain of the
representations and warranties of the Company set forth in the Merger
Agreement will not be breached unless the matter constituting the breach would
have a material adverse effect on the financial condition, properties,
business, results of operations or prospects of the Company and its
subsidiaries taken as a whole (a "Company Material Adverse Effect"); provided,
however, that any adverse effect that is caused by conditions affecting the
economy or security markets generally shall not be taken into account in
determining whether there has been a Company Material Adverse Effect and any
adverse effect that is caused by conditions affecting the primary industry in
which the Company currently competes shall not be taken into account in
determining whether there has been a Company Material Adverse Effect (provided
that such effect does not adversely affect the Company in a disproportionate
manner). Certain of the representations and warranties of the Parent set forth
in the Merger Agreement will not be breached unless the matter constituting
the breach would have a material adverse effect on the ability of Parent or
Purchaser to conduct the Offer or consummate the Merger or any of the other
material transactions contemplated by the Merger Agreement (a "Parent Material
Adverse Effect").
 
  Agreements of FD. Pursuant to the terms of the Merger Agreement, FD has
agreed, among other things, to tender in, and not withdraw from, the Offer,
all Shares (including the FD Shares) owned by it and its affiliates. In
addition, FD currently holds an option (the "FD Option") to purchase 1,768,970
Shares which will be canceled upon consummation of the Offer. The FD Option
has an exercise price of $13.1274 per share, which is greater than the Offer
Price, and, if not canceled in connection with the Offer, would expire on
December 11, 1998.
 
  Conduct of Business. The Company has agreed that, prior to the date on which
Parent's representatives are elected to the Board (unless Parent shall
otherwise approve in writing, which approval shall not be unreasonably

Corporation will jointly and severally, after the Effective Time, indemnify,
defend and hold harmless, each person who is now, or has been at any time

Effective Time a director, officer, employee or agent of the Company or any of
its subsidiaries (when acting in such capacity), against any costs or expenses
(including reasonable attorneys' fees and expenses), judgments, settlement
amounts, fines, losses, claims, demands, damages or liabilities (collectively,

                                      24
<PAGE>

of incorporation, bylaws and other agreements in effect as of the date of the
Merger Agreement to indemnify such individual. In addition, pursuant to the
Merger Agreement, the Company will purchase, and Parent will reimburse the
Company at the Closing (as defined in the Merger Agreement) for the fully
prepaid premium expense incurred for "Prior Acts" Directors' & Officers'
Liability Insurance (the "D&O Insurance") to be effective as of the date of
the Merger Agreement. The term of the D&O Insurance will be six (6) years from
the date of the Merger Agreement without restriction as to when any alleged or
actual wrongful acts or omissions may have occurred up to and including the
date of sale of the FD Shares to Purchaser pursuant to the Offer. Subject to
the provisions and limitations of the Merger Agreement, the D&O Insurance will
provide individual directors and officers liability coverage and corporate
reimbursement coverage. In addition, the D&O Insurance is noncancellable
except for the nonpayment of premium or the ultimate failure of the FD Shares
being purchased by Purchaser.
 
  Conditions to the Merger. Pursuant to the Merger Agreement, if Purchaser
shall have purchased Shares pursuant to the Offer, the respective obligations
of Parent, Purchaser and the Company to consummate the Merger shall be subject

  execution and delivery of the Merger Agreement and the consummation of the

  have enacted, issued, promulgated, enforced or entered any statute, rule,
  regulation, judgment, decree, injunction or other order (whether temporary,

retained by it or any of its subsidiaries) not to, directly or indirectly
through another person or entity, initiate, solicit or otherwise facilitate
any inquiries or the making of any proposal or offer with respect to a merger,
reorganization, share exchange, consolidation or similar transaction
involving, or any purchase of all or any significant portion of the assets or
any equity securities of, the Company or any of its subsidiaries (any such
proposal or offer being hereinafter referred to as an "Acquisition Proposal").
The Company has further agreed that neither it nor any of its subsidiaries nor
any of their respective directors or employees will, and that it will direct
and use its best efforts to cause its and its subsidiaries agents and
representatives (including any investment banker, attorney or accountant
retained by it or any of its subsidiaries) not to, directly or indirectly
through another person or entity, engage or participate in any negotiations
concerning, or provide any confidential information or data to, or have any
discussions with, any person relating to an Acquisition Proposal, or otherwise
attempt to make or implement an Acquisition Proposal; provided, however, that
if at any time prior to the acceptance for payment of Shares pursuant to the
Offer, the Board determines in good faith, after taking into consideration the
advice of its outside legal counsel, that it is likely to be required in order
for its members to comply with their fiduciary duties under applicable law,
the Company may, in response to an inquiry, proposal or offer for an
Acquisition Proposal which was not solicited subsequent to the date of the
Merger Agreement, (x) furnish non-public information with respect to the
Company to any such person pursuant to a confidentiality agreement on terms
substantially similar to the Confidentiality Agreement entered into between
the Company and Parent prior to the execution of the Merger Agreement and (y)
participate in discussions and negotiations regarding such inquiry, proposal
or offer; and provided, further, that nothing contained in the Merger
Agreement shall prevent the Company or its Board from complying with Rules
14d-9 and 14e-2 promulgated under the Exchange Act with regard to any proposed
Acquisition Proposal.
 
  The Board may withdraw its recommendation of the Merger and the other
transactions contemplated by the Merger Agreement, or approve or recommend or
cause the Company to enter into an agreement with respect to a Superior
Proposal (as defined below), if the Board determines in its good faith
judgment, after taking into consideration the advice of its outside legal
counsel, that it is likely to be required in order for its members to comply
with their fiduciary duties under applicable law; provided, however, that the
Company shall not be entitled to enter into any agreement with respect to a
Superior Proposal unless the Merger Agreement is concurrently terminated in
accordance with its terms. A "Superior Proposal" means any bona fide proposal
to acquire directly or indirectly for consideration consisting of cash and/or
securities more than 50% of the Shares then outstanding or all or
substantially all the assets of the Company and its subsidiaries, taken as a
whole, and otherwise on terms which the Board by a majority vote determines in
its good faith judgment (after consultation with the Company's financial
advisor or another financial adviser of nationally recognized reputation) to
be reasonably capable of being completed (taking into account all material
legal, financial, regulatory and other aspects of the proposal and the Person
making the proposal, including the availability of financing therefor) and
more favorable to the Company's stockholders from a financial point of view
than transactions contemplated by the Merger Agreement.
 
  Termination of the Merger Agreement. Subject to certain conditions and
exceptions set forth in the Merger Agreement, the Merger Agreement may be
terminated at any time prior to the Effective Time, whether before or after
its approval by the stockholders of the Company thereof, (i) by mutual written
consent of the Company
 
                                      26
<PAGE>
 
(through the Continuing Directors, the Special Directors or their designated
successors), Parent and Purchaser, by action of their respective boards of
directors; (ii) by either Parent or the Company, by action of their respective
boards of directors if (A) any Order permanently restraining, enjoining or
otherwise prohibiting the Merger shall be entered (whether before or after the
approval by the stockholders of the Company) and such Order is or shall have
become nonappealable, provided that the party seeking to terminate this
Agreement shall have used its reasonable efforts to remove or lift such Order,
or (B) the Minimum Condition shall not have been satisfied on or before
December 31, 1998; (iii) by the Company if (A) (1) Parent fails to commence
the Offer as provided by the Merger Agreement or (2) after December 31, 1998,
Parent shall have failed to accept Shares for payment pursuant to the Offer,
(B) the Offer is terminated or withdrawn pursuant to its terms without any
Shares being purchased thereunder, (C) prior to Parent's purchase of Shares
pursuant to the Offer, (1) the Company enters into a binding written agreement
with respect to a Superior Proposal after fully complying with the terms of
the Merger Agreement and (2) the Company concurrently with such termination
pays to Parent in immediately available funds all expense reimbursements due
Parent pursuant to the terms of the Merger Agreement, including the
termination fee, or (D) there has been a material breach by Parent or
Purchaser of any representation, warranty, covenant or agreement contained in
this Agreement that is not curable or, if curable, is not cured prior to the
earlier of (1) twenty (20) days after written notice of such breach is given
by the Company to Parent and (2) two (2) business days before the date on
which the Offer expires; and (iv) by Parent and Purchaser if (A) after
December 31, 1998, Parent shall not have paid for Shares pursuant to the
Offer, (B) the Board shall have withdrawn or modified its approval or
recommendation of this Agreement in a manner materially adverse to Parent, or
(C) Parent shall have terminated the Offer in accordance with the provisions
of the section entitled "THE TENDER OFFER--19. Certain Conditions of the
Offer."
 
  If the Merger Agreement is terminated for any of the above reasons (subject
to the provisions of the Merger Agreement), the Merger Agreement shall become
void and be of no further effect; provided, however, that such a termination
shall not relieve any party to the Merger Agreement of any liability or
damages resulting from any breach of the Merger Agreement and, provided,
further, that, subject to certain exceptions set forth in the Merger
Agreement, the Company shall reimburse Parent in the amount of $400,000 as
reimbursement for all of Parent's costs and expenses in connection with the
Merger Agreement, the Offer and the Merger. Subject to certain exceptions, the
Company shall promptly, but in no event later than two days after the date of
such request, pay Parent a termination fee of $1.5 million in lieu of any
liability or obligation to pay damages (other than the $400,000 reimbursement
payable to Parent for its costs and expenses) if (i) there shall be an
Acquisition Proposal existing at the time of termination of the Merger
Agreement by Parent and Purchaser and (A) Parent and Purchaser shall have
terminated the Merger Agreement because the Board has withdrawn or modified
its approval or recommendation of the Merger Agreement in a manner materially
adverse to Parent or (B) Parent and Purchaser shall have terminated the Merger
Agreement because of Parent's termination of the Offer in accordance with the
provisions of the section entitled "THE TENDER OFFER--19. Certain Conditions
of the Offer." of the Merger Agreement or (ii) if there shall not have been a
material breach of any representation, warranty, covenant or agreement on the
part of Parent or Purchaser and the Company shall have terminated the Merger
Agreement to accept a Superior Proposal.
 
  Amendment and Waiver. The Merger Agreement can only be amended by a written
agreement executed by the parties signatory thereto.
 
  Expenses. Whether or not the Merger is consummated, all costs and expenses
incurred in connection with the negotiation, execution and delivery of the
Merger Agreement, the Merger and the other transactions contemplated by the
Merger Agreement, including the Offer, shall be paid by the party incurring
such expense, except that expenses incurred in connection with the filing fee
for the Proxy Statement and the printing and mailing of such documents shall
be borne by the Parent.
 
 THE CONFIDENTIALITY AGREEMENT
 
  Pursuant to a letter agreement, dated July 28, 1998 (the "Confidentiality
Agreement"), the Company proposed to disclose to Parent certain non-public or
confidential information in order to evaluate a possible
 
                                      27
<PAGE>
 
transaction involving the two companies. Pursuant to the Confidentiality
Agreement, Parent agreed not to use or disclose such confidential information
and to abstain from soliciting executive, management and other key employees
for a period of two (2) years after the date of the Confidentiality Agreement.
 
 THE AMENDED MARKETING AGREEMENT
 
  Worldwide Use of Parent for Environmental Services. Effective upon the
consummation of the Offer, the Amended Marketing Agreement provides that,
subject to the conditions set forth therein, FD and subsidiaries of which FD
owns more than 50% (collectively, the "Fluor Daniel Group"), will promote the
use of Parent and subsidiaries of which Parent owns more than 50%
(collectively, the "IT Group"), on a worldwide basis for certain environmental
services (the "Environmental Services") that are related or incidental to FD's
engineering and construction business. There was no separate monetary
consideration given in connection with the execution of this agreement. The
agreement provides for the continuation of the services under contracts
presently being performed by FD for the Company, and by the Company for FD, on
the terms previously agreed to by such parties under the existing marketing
agreement as well as a Steering Committee consisting of two senior executives
of each of FD and Parent, for purposes of discussing and promoting joint
marketing efforts under the agreement. The Amended Marketing Agreement has a
term of four (4) years. The Amended Marketing Agreement is filed as Exhibit
(c)(2) to the Schedule 14D-1 filed by Parent and Purchaser and is incorporated
herein by reference.
 
  Specified Environmental Services. Subject to specific exceptions set forth
in the Amended Marketing Agreement, the Environmental Services for which the
Fluor Daniel Group will promote the IT Group, are investigation, evaluation,
design, feasibility studies, management and pollution prevention, project
management, remediation, permitting, quality control, start-up assistance,
licensing and consulting (including incidental project finance, procurement,
construction and maintenance) relating to (i) the treatment of groundwater,
wastewater, soil and hazardous waste, or (ii) air emissions controls. The
Environmental Services exclude certain projects, such as FD's Fernald and
Hanford projects and other U.S. Department of Energy management and
operations, operating and maintenance, and management and integration
projects, and certain categories of projects.
 
  The IT Group has committed to use commercially reasonable efforts to perform
Environmental Services as may be requested by FD, but will not be obligated to
provide such services. With respect to any clients common to the Fluor Daniel
Group and the IT Group, the IT Group will have the marketing lead for projects
that primarily involve Environmental Services and FD will have the marketing
lead for projects that primarily involve engineering and construction
services. In addition, pursuant to the Amended Marketing Agreement, the Fluor
Daniel Group and the IT Group have agreed to explore mutually beneficial ways
to involve each other in other future projects.
 
  Restrictions on Environmental Acquisitions. The Amended Marketing Agreement
also provides that the Fluor Daniel Group will not acquire or merge with any
entity which is engaged primarily in performing Environmental Services without
the prior written consent of the Company. If the Fluor Daniel Group acquires
or merges with an entity which is not engaged primarily in performing
Environmental Services, but which performs some Environmental Services, the
Fluor Daniel Group will be permitted to perform Environmental Services through
such entity and the Amended Marketing Agreement will continue on a non-
exclusive basis. However, the Fluor Daniel Group would be required to enter
into discussions with the IT Group with a view to determining whether the IT
Group would have any interest in acquiring the portion of the entity acquired
by the Fluor Daniel Group which performs Environmental Services, other than
services for the United States government (the "Environmental Portion").
 
  If after 60 days following any such acquisition, Parent and the Fluor Daniel
Group have not reached an agreement concerning the Environmental Portion, then
the Fluor Daniel Group will be required to engaged in a good faith effort to
divest the Environmental Portion. If the Fluor Daniel Group does not divest
the Environmental Portion or decide to liquidate or phase out the business of
the Environmental Portion, then the Fluor Daniel Group will give consideration
to any request by Parent that the terms and conditions of the
 
                                      28
<PAGE>
 
Amended Marketing Agreement be adjusted to avoid an inequitable hardship to
Parent resulting from any material diminution of value of the Amended
Marketing Agreement arising from such acquisition by the Fluor Daniel Group.
 
  Intercompany Services. The Amended Marketing Agreement also allows for
certain services to be provided between Parent and FD at specified rates of
compensation. The Intercompany Services Agreement, dated October 27, 1998, by
and among Parent, the Company and FD (the "Intercompany Agreement") sets forth
certain terms for performance and payment, as well as a form of written
request for services and work releases. The Intercompany Agreement is filed as
Exhibit (c)(3) to the Schedule 14D-1 filed by Parent and Purchaser and is
incorporated herein by reference.
 
  Offices; Prohibition on Use of FD Name. The Amended Marketing Agreement
provides for the orderly disentanglement of the seven offices of the Company
presently co-located with offices of FD as well as for the Company to promptly
stop using the name and logo of FD, and to obtain such third-party consents,
licenses and permits as may be necessary to allow the complete disentanglement
of the Company and FD promptly following consummation of the Offer.
 
 DISSENTERS' RIGHTS IN THE MERGER
 
  No appraisal rights are available in connection with the Offer. If the
Merger is consummated, however, stockholders of the Company will have certain
rights under the DGCL to dissent and demand appraisal of, and to receive
payment in cash of the fair value of, their Shares. Stockholders who perfect
such rights by complying with the procedures set forth in Section 262 will
have the fair value of their Shares determined by the Delaware trial court and
will be entitled to receive a cash payment equal to such fair value from the
Surviving Corporation. In addition, such dissenting stockholders would be
entitled to receive payment of a fair rate of interest from the date of
consummation of the Merger on the amount determined to be the fair value of
their Shares. In determining the fair value of the Shares, the court is
required to take into account all relevant factors; provided, however, that
any appreciation or depreciation in market value resulting from the
transactions contemplated by the Merger Agreement will be excluded.
Accordingly, such determination could be based upon considerations other than,
or in addition to, the market value of the Shares, including, among other
things, asset values and earning capacity.
 
  THE FOREGOING SUMMARY OF THE RIGHTS OF DISSENTING STOCKHOLDERS DOES NOT
PURPORT TO BE A COMPLETE STATEMENT OF THE PROCEDURES TO BE FOLLOWED BY
STOCKHOLDERS DESIRING TO EXERCISE ANY AVAILABLE APPRAISAL RIGHTS AND IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SECTION 262
INCLUDED HEREWITH IN ANNEX A. THE PRESERVATION AND EXERCISE OF APPRAISAL
RIGHTS ARE CONDITIONED ON STRICT ADHERENCE TO THE APPLICABLE PROVISIONS OF THE
DGCL.
 
15. GOING PRIVATE TRANSACTIONS
 
  The Merger or another business combination following the purchase of Shares
pursuant to the Offer in which the Purchaser seeks to acquire the remaining
Shares not held by it would have to comply with any applicable Federal law
operating at the time of its consummation. Rule 13e-3 under the Exchange Act
is applicable to certain "going private" transactions. If applicable, Rule
13e-3 would require, among other things, that certain financial information
concerning the Company and certain information relating to the fairness of the
Merger or such other business combination and the consideration offered to
minority stockholders be filed with the Commission and disclosed to minority
stockholders prior to the consummation of the Merger or such other business
combination. However, Rule 13e-3 will not be applicable to the Merger or any
such other business combination if (i) the Shares are deregistered under the
Exchange Act prior to the Merger or other business combination or (ii) the
Merger or other business combination is consummated within one year after the
Purchase of the Shares pursuant to the Offer and the value of the
consideration paid per Share in the Merger or other business combination
(measured at the time of consummation of the Merger) is at least equal to the
Offer Price.

16. INTERESTS OF CERTAIN PERSONS IN THE OFFER AND THE MERGER
 
  Consummation of the Offer and the Merger will have certain effects under
certain compensation and incentive plans and arrangements in which officers
and directors of the Company are participants, as summarized below.
 
  Retention Plan. The Company has in place an executive retention plan (the
"Retention Plan") covering six key executives including all executive officers
of the Company. The Retention Plan provides that participating executives will
be paid bonuses as follows: 33% of the executive's 1998 base salary on January
1, 1999; and 67% of the executive's 1998 base salary on January 1, 2000. In
the event a participating executive is terminated because of a change of
control or an involuntary reduction in force, the balance due to such
executive will be paid in full. If a participating executive leaves
voluntarily or is terminated for cause or for lack of performance, the balance
to be paid is forfeited. As of the date hereof, none of the executive officers
of the Company covered by the Retention Plan, other than Mr. Barber, have been
informed by Parent that their employment will be terminated in connection with
the Offer or the Merger.
 
  Severance Plan. The Company has in place a severance plan (the "Severance
Plan") covering 12 employees, including all executive officers of the Company
other than Mr. Barber, which is activated upon a Change of Control of the
Company (as defined in the Severance Plan), which includes the Merger. The
Severance Plan provides for the payment of the following compensation upon the
termination in certain circumstances of a participant's employment with the
Company within one year following a Change of Control of the Company; (i) a
cash lump sum equal to the sum of (a) the participant's annual salary through
the date of such termination, to the extent not theretofore paid, (b) the
participant's target bonus amount, pro-rated for the period ending on the date
of termination, and (c) any deferred compensation and accrued time off with
pay, to the extent not theretofore paid, and (ii) an amount equal to a
multiple of either one or two times the participant's base salary as
determined by the Compensation Committee of the Board. As of the date hereof,
none of the executive officers of the Company covered by the Severance Plan
have been informed by Parent that their employment will be terminated in
connection with the Offer or the Merger. A copy of the Severance Plan has been
filed as Exhibit 4 to the Schedule 14D-9.
 
  Settlement and Release Agreement. Mr. Barber entered into a Settlement and
Release Agreement with the Company dated as of September 11, 1998 (the
"Settlement and Release Agreement"), which has been filed as Exhibit 5 to the
Schedule 14D-9. Pursuant to the Settlement and Release Agreement, Mr. Barber
has agreed to resign his employment with the Company, as well as all offices
and directorships he holds with the Company upon a Change of Control of the
Company (as defined in the Settlement and Release Agreement), which includes
the consummation of the Offer. In exchange for such resignation, the Company
has agreed to provide Mr. Barber with (i) a lump sum payment of $780,000, net
of any federal withholding taxes and other deductions the Company is required
to make by law, and (ii) payment for outplacement services in accordance with
the Company's customary procedures not to exceed $20,000. Pursuant to the
Settlement and Release Agreement, Mr. Barber agrees to release the Company and
any related companies, and their employees and directors, from any claims or
demands based on Mr. Barber's employment with the Company or the termination
of that employment (including all claims under his employment agreement); and
the Company agrees to release Mr. Barber from all claims or demands based on
Mr. Barber's employment with the Company or the termination of that
employment. Mr. Barber further agrees that he will not, from the date of the
Settlement and Release Agreement through June 1, 1999, directly or indirectly,
provide services, advice or other assistance to a competitor of the Company
concerning or with respect to historic clients of the Company.
 
  In addition, the Merger Agreement contains certain provisions with respect
to indemnification of directors and executive officers, advancement of
expenses and maintenance of directors' and officers' liability insurance
subsequent to the Effective Time. See "THE TENDER OFFER--14. The Merger
Agreement and Related Agreements--Indemnification."

(8) On May 10, 1996 (the "Closing Date") the Company closed a series of
    transactions (the "Fluor Daniel Transactions") pursuant to which it issued
    to FD the FD Shares (approximately 54.5 percent of the total shares
    outstanding on the Closing Date). On December 11, 1996, the Company
    granted FD an option to purchase 1,366,000 shares of Common Stock at a
    purchase price of $17.00 per share, which option was adjusted pursuant to
    the Fluor Daniel Transactions to represent the right to purchase 1,768,970

17. DIVIDENDS AND DISTRIBUTIONS.
 
  According to the Company's 1997 Annual Report on Form 10-K, the Company has
not paid cash dividends to date and intends to retain any future earnings for
use in the business.
 
  Pursuant to the terms of the Merger Agreement, prior to the time that the
Parent Directors are elected to the Board and represent at least a majority of
such directors, the Company will not, without the consent of Parent, split,
combine or reclassify the Shares or declare, set aside or pay any dividend
payable in cash, stock or property with respect to the Shares.
 
18. EFFECTS OF THE OFFER ON THE MARKET FOR SHARES; EXCHANGE LISTING AND
EXCHANGE ACT REGISTRATION.
 
  The purchase of Shares pursuant to the Offer will reduce the number of
Shares that might otherwise trade publicly and could reduce the number of
holders of Shares, which could adversely affect the liquidity and market value
of any remaining Shares held by the public. It is expected that, following the
Offer, a large percentage of the Shares will be owned by Purchaser.
 
  Possible Effects of the Offer on the Market for the Shares. The purchase of
Shares pursuant to the Offer will reduce the number of Shares that might
otherwise trade publicly and could adversely affect the liquidity and market
value of the remaining Shares held by the public. The purchase of Shares
pursuant to the Offer can also be expected to reduce the number of holders of
Shares. Purchaser cannot predict whether the reduction in the number of Shares
that might otherwise trade publicly would have an adverse or beneficial effect
on the market price for or marketability of the Shares or whether it would
cause future market prices to be greater or less than the Offer Price
therefor.
 
  Stock Quotation. Depending upon the number of Shares purchased pursuant to
the Offer, the Shares may no longer meet the requirements of the National
Association of Securities Dealers, Inc. (the "NASD") for continued inclusion
on Nasdaq, which require that an issuer have at least 200,000 publicly held
shares, held by a least 400 stockholders or 300 stockholders of round lots,
with a market value of at least $1 million, and have net tangible assets of at
least $1 million or $4 million, depending on profitability levels during the
issuer's four most recent fiscal years. If these standards are not met, the
Shares might nevertheless continue to be included in The Nasdaq Stock Market,
with quotations published in the NASD Automatic Quotation System "additional
list" or in one of the "local lists." However, if the number of holders of the
Shares were to fall below 300, or if the number of publicly-held Shares were
to fall below 100,000 or there were not at least two registered and active
market makers for the Shares, the NASD's rules provide that the Shares would
no longer be "qualified" for listing on Nasdaq, and The Nasdaq Stock Market
would cease to provide any quotations. Shares held directly or
 
                                      32
<PAGE>
 
indirectly by directors, officers or beneficial owners of more than 10% of the
Shares are not considered as being publicly held for this purpose. If, as a
result of the purchase of Shares pursuant to the Offer or otherwise, the
Shares no longer meet the requirements of the NASD for continued inclusion on
Nasdaq or in any other tier of The Nasdaq Stock Market, as the case may be,
the market for Shares could be adversely affected.
 
  In the event that the Shares no longer meet the requirements of the NASD for
continued inclusion in any tier of The Nasdaq Stock Market, it is possible
that the Shares would continue to trade in the over-the-counter market and
that price quotations would be reported by other sources. The extent of the
public market for the Shares and the availability of such quotations would,
however, depend upon the number of holders of Shares remaining at such time,
the interest in maintaining a market in Shares on the part of securities
firms, the possible termination of registration of the Shares under the
Exchange Act, as described below, and other factors.
 
 EXCHANGE ACT REGISTRATION
 
  The Shares are currently registered under the Exchange Act. Such
registration may be terminated upon application by the Company to the
Commission if the Shares are not listed on a national securities exchange and
there are fewer than 300 record holders. The termination of the registration
of the Shares under the Exchange Act would substantially reduce the
information required to be furnished by the Company to holders of Shares and
to the Commission and would make certain provisions of the Exchange Act, such
as the short-swing profit recovery provisions of Section 16(b), the
requirements of furnishing a proxy statement in connection with stockholders'
meetings and the requirements of Rule 13e-3 under the Exchange Act with
respect to "going private" transactions, no longer applicable to the Shares.
In addition, "affiliates" of the Company and persons holding "restricted
securities" of the Company may be deprived of the ability to dispose of such
securities pursuant to Rule 144 promulgated under the Securities Act of 1933,
as amended. If registration of the Shares under the Exchange Act were
terminated, the Shares would no longer be "margin securities" or be eligible
for Nasdaq market reporting. Parent currently intends to seek to cause the
Company to terminate the registration of the Shares under the Exchange Act as
soon after the Effective Time as the requirements for termination of
registration are met.
 
 MARGIN REGULATIONS
 
  The Shares are currently "margin securities" under the regulations of the
Board of Governors of the Federal Reserve System (the "Federal Reserve
Board"), which has the effect, among other things, of allowing brokers to
extend credit on the collateral of such Shares for the purpose of buying,
carrying or trading in securities ("Purpose Loans"). Depending upon factors
similar to those described above regarding the continued listing, public
trading and market quotations of the Shares, it is possible that, following
the consummation of the transactions contemplated by the Merger Agreement, the
Shares would no longer constitute "margin securities" for the purposes of the
margin regulations of the Federal Reserve Board and therefore could no longer
be used as collateral for Purpose Loans made by brokers.
 
19. CERTAIN CONDITIONS OF THE OFFER.
 
  Notwithstanding any other provision of the Offer or the Merger Agreement,
and subject to any applicable rules and regulations of the Commission,
including Rule 14e-1(c) relating to Parent's obligation to pay for or return
tendered Shares after termination or withdrawal of the Offer, Parent shall not
be required to accept for payment or pay for any Shares tendered pursuant to
the Offer, shall delay the acceptance for payment of any Shares and if
required by the Merger Agreement, shall extend the Offer by one or more
extensions until December 31, 1998, and may terminate the Offer at any time
after December 31, 1998 if (i) less than the Minimum Share Number is tendered
pursuant to the Offer by the expiration of the Offer and not withdrawn;
(ii) any applicable waiting period under the HSR Act has not expired or
terminated prior to the Expiration Date of the Offer; or (iii) at any time
after the date of the Merger Agreement, and before acceptance for payment of
any Shares, any of the following events shall occur and be continuing on or
after December 31, 1998:
 
    (a) there shall have been any action taken, or any statute, rule,
  regulation, judgment, order or injunction promulgated, entered, enforced,
  enacted, issued or deemed applicable to the Offer or the Merger
 
                                      33
<PAGE>
 
  by any domestic or foreign court or other governmental entity (other than
  the application of the waiting period provisions of the HSR Act to the
  Offer or to the Merger) that, in the reasonable judgment of Parent, would
  be expected to, directly or indirectly (i) prohibit, or impose any material
  limitations on, Parent's ownership or operation of all or a material
  portion of the Company's businesses or assets, or compel Parent to dispose
  of or hold separate any material portion of the business or assets of the
  Company or Parent and its respective subsidiaries, in each case taken as a
  whole, (ii) prohibit, or make illegal, the acceptance for payment, payment
  for or purchase of Shares or the consummation of the Offer, the Merger or
  the other transactions contemplated by the Merger Agreement, (iii) result
  in the material delay in or restricts the ability of Parent, or renders
  Parent unable, to accept for payment, pay for or purchase some or all of
  the Shares, or (iv) impose material limitations on the ability of Parent
  effectively to exercise full rights of ownership of the Shares, including
  the right to vote the Shares purchased by it on all matters properly
  presented to the Company's stockholders;
 
    (b) (i) the representations and warranties of the Company set forth in
  this Agreement shall not be true and correct in any material respect as of
  the date of the Merger Agreement and as of consummation of the Offer as
  though made on or as of such date (except for representations and
  warranties made as of a specified date) but only if the respects in which
  the representations and warranties made by the Company (without giving
  effect to any "materiality" limitations or references to "material adverse
  effect" set forth therein) are inaccurate would in the aggregate have a
  Company Material Adverse Effect, (ii) the Company shall have failed to
  comply with its covenants and agreements contained in this Agreement in all
  material respects which failure is likely to have a Company Material Effect
  and, with respect to any breach or failure described in clause (b)(i) or
  (b)(ii) above that can be cured, the breach or failure shall not have been
  cured prior to ten (10) business days after Parent has furnished the
  Company with written notice of such breach or failure or (iii) there shall
  have occurred any events or changes which have had or which are likely to
  have a Company Material Adverse Effect;
 
    (c) the Board shall have withdrawn, or modified or changed in a manner
  adverse to Parent (including by amendment of the Schedule 14D-9), its
  recommendation of the Offer, the Merger Agreement or the Merger, or
  recommended another proposal or offer for the acquisition of the Company,
  or the Board, shall have resolved to do any of the foregoing;
 
    (d) the Merger Agreement shall have terminated in accordance with its
  terms; or
 
    (e) there shall have occurred and continue to exist (i) any general
  suspension of, or limitation on prices for, trading in securities on the
  NYSE (other than a shortening of trading hours or any coordinated trading
  halt triggered solely as a result of a specified increase or decrease in a
  market index), (ii) the declaration of any banking moratorium or any
  suspension of payments in respect of banks, or any limitation (whether or
  not mandatory) by any Governmental Entity (as defined in the Merger
  Agreement) on, or other event materially adversely affecting, the extension
  of credit by lending institutions in the United States, or (iii) a
  commencement of a war or armed hostilities directly involving the United
  States which has and continues to have a material adverse effect on the
  trading of securities on the NYSE;
 
which in the reasonable judgment of Parent, in any such case, makes it
inadvisable to proceed with the Offer or the acceptance for payment of or
payment for the Shares.
 
  The foregoing conditions, other than condition (i) above, are for the sole
benefit of Parent and may be waived by Parent, in whole or in part at any time
and from time to time, in the sole discretion of Parent. The failure by Parent
at any time to exercise any of the foregoing rights shall not be deemed a
waiver of any such right and each such right shall be deemed an ongoing right
which may be asserted at any time and from time to time, except as otherwise
provided for in the Merger Agreement.

20. CERTAIN LEGAL MATTERS; REGULATORY APPROVALS.
 
 GENERAL
 
  Except as described below, based upon an examination of publicly available
filings made by the Company with the Commission, other publicly available
information about the Company and the representations and warranties of the
Company in the Merger Agreement, neither Purchaser nor Parent is aware of any
license or regulatory permit that appears to be material to the business of
the Company and its subsidiaries, taken as a whole, that might be adversely
affected by Purchaser's acquisition of Shares pursuant to the Offer, or of any
approval or other action by any governmental, administrative or regulatory
agency or authority or public body, domestic or foreign, that would be
required for the acquisition or ownership of Shares by Purchaser pursuant to
the Offer. Should any such approval or other action be required, it is
presently contemplated that such approval or action would be sought except as
described below in this Section under "State Takeover Statutes." While, except
as otherwise expressly described herein, Purchaser does not currently intend
to delay acceptance for payment of Shares tendered pursuant to the Offer
pending the outcome of any such matter, there can be no assurance that any
such approval or other action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to the
Company's business or that certain parts of the Company's business might not
have to be disposed of in the event that such approvals were not obtained or
such other actions were not taken or in order to obtain any such approval or
other action, any of which could cause Purchaser to decline to accept for
payment or pay for any Shares tendered. Purchaser's obligation under the Offer
to accept for payment and pay for Shares is subject to the Offer Conditions,
including conditions relating to legal matters discussed in this Section 20.
 
 ANTITRUST
 
  Under the HSR Act and the rules that have been promulgated thereunder by the
Federal Trade Commission ("FTC"), certain acquisition transactions may not be
consummated unless certain information has been furnished to the Antitrust
Division of the Department of Justice (the "Antitrust Division") and the FTC
and certain waiting period requirements have been satisfied. The acquisition
of Shares pursuant to the Offer is subject to such requirements.
 
  Parent expects to file a Notification and Report Form with respect to the
Offer under the HSR Act as soon as practicable following commencement of the
Offer. The waiting period under the HSR Act with respect to the Offer will
expire at 11:59 p.m. Washington D.C. time, on the 15th day after the date such
form is filed, unless early termination of the waiting period is granted. In
addition, the Antitrust Division or the FTC may extend such waiting period by
requesting additional information or documentary material from Parent. If such
a request is made with respect to the Offer, the waiting period related to the
Offer will expire at 11:59 p.m. Washington D.C. time on the 10th day after
substantial compliance by Parent with such request. With respect to each
acquisition, the Antitrust Division or the FTC may issue only one request for
additional information. In practice, complying with a request for additional
information or material can take a significant amount of time. In addition, if
the Antitrust Division or the FTC raises substantive issues in connection with
a proposed transaction, the parties may engage in negotiations with the
relevant governmental agency concerning possible means of addressing those
issues and may agree to delay consummation of the transaction while such
negotiations continue. Expiration or termination of applicable waiting periods
under the HSR Act is a condition to Purchaser's obligation to accept for
payment and pay for Shares tendered pursuant to the Offer.
 
  The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the proposed purchase of the Shares
by Purchaser pursuant to the Offer. At any time before or after such purchase,
the Antitrust Division or the FTC could take such action under the antitrust
laws as it deems necessary or desirable in the public interest, including
seeking to enjoin the transaction or seeking divestiture of the Shares so
acquired or divestiture of substantial assets of Purchaser, Parent or the
Company. Litigation seeking similar relief could be brought by private
parties.
 
                                      35
<PAGE>
 
  Parent does not believe that consummation of the Offer and the other
transactions contemplated by the Merger Agreement will result in violation of
any applicable antitrust laws. However, there can be no assurance that a
challenge to the Offer and the other transactions contemplated by the Merger
Agreement on antitrust grounds will not be made, or if such a challenge is
made, what the result will be. See Section 19 for certain conditions to the
purchase of the Shares in the Offer, including conditions with respect to
litigation and certain governmental actions.
 
 STATE TAKEOVER STATUTES
 
  A number of states have adopted "takeover" statutes that purport to apply to
attempts to acquire corporations that are incorporated in such states, or
whose business operations have substantial economic effects in such states, or
which have substantial assets, security holders, employees, principal
executive offices or places of business in such states.
 
  In Edgar v. MITE Corporation, the Supreme Court of the United States
invalidated on constitutional grounds the Illinois Business Takeover Act,
which, as a matter of state securities law, made takeovers of corporations
meeting certain requirements more difficult. However, in CTS Corp. v. Dynamics
Corp. of America, the Supreme Court held that a state may, as a matter of
corporate law and, in particular, those laws concerning corporate governance,
constitutionally disqualify a potential acquirer from voting on the affairs of
a target corporation without prior approval of the remaining stockholders,
provided that such laws were applicable under certain conditions, in
particular, that the corporation has a substantial number of stockholders in
the state and is incorporated there.
 
  In 1998, the Company, directly or through subsidiaries, has leased space in
25 states and performed work in 49 states in the United States, and some of
these states have enacted takeover statutes. Purchaser does not know whether
any of these statutes will, by their terms, apply to the Offer, and Purchaser
has not complied with any such statutes. To the extent that certain provisions
of these statutes purport to apply to the Offer, Purchaser believes that there
are reasonable bases for contesting such statutes. If any person should seek
to apply any state takeover statute, Purchaser would take such action as then
appears desirable, which action may include challenging the validity or
applicability of any such statute in appropriate court proceedings. If it is
asserted that one or more takeover statutes apply to the Offer and it is not
determined by an appropriate court that such statute or statutes do not apply
or are invalid as applied to the Offer, Purchaser might be required to file
certain information with, or receive approvals from, the relevant state
authorities, and Purchaser might be unable to accept for payment or pay for
Shares tendered pursuant to the Offer, or be delayed in continuing or
consummating the Offer. In such case, Purchaser may not be obligated to accept
for payment or pay for Shares tendered pursuant to the Offer.
 
21. FEES AND EXPENSES.
 
  Purchaser has retained MacKenzie Partners, Inc. to act as the Information
Agent and BankBoston, N.A. to act as the Depositary in connection with the
Offer. The Information Agent may contact holders of Shares by mail, telephone,
telegraph and personal interview and may request brokers, dealers and other
nominee stockholders to forward the Offer materials to beneficial owners. The
Information Agent will receive a fee for services as Information Agent not to
exceed $7,500 and will be reimbursed for certain out-of-pocket expenses. The
Depositary will receive reasonable and customary compensation for services
relating to the Offer and will be reimbursed for certain out-of-pocket
expenses. Purchaser has also agreed to indemnify the Information Agent and the
Depositary against certain liabilities and expenses in connection with the
Offer, including certain liabilities under the federal securities laws.
 
  Purchaser will not pay any fees or commissions to any broker or dealer or
any other person for soliciting tenders of Shares pursuant to the Offer (other
than to the Information Agent). Brokers, dealers, commercial banks, trust
companies and other nominees will, upon request, be reimbursed by Purchaser
for customary mailing and handling expenses incurred by them in forwarding
offering materials to their customers.
 
                                      36

  Except as set forth above, Purchaser will not pay any fees or commissions to
any broker or dealer or other person for soliciting tenders of Shares pursuant
to the Offer. Brokers, dealers, commercial banks and trust companies will be
reimbursed by Purchaser for customary mailing and handling expenses incurred
by them in forwarding the offering materials to their customers.
 
22. MISCELLANEOUS.
 
  The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the
securities, blue sky or other laws of such jurisdiction. Purchaser may, in its
discretion, however, take such action as it may deem necessary to make the
Offer in any jurisdiction and extend the Offer to holders of Shares in any
such jurisdiction.
 
  No person has been authorized to give any information or to make any
representation on behalf of Purchaser not contained herein or in the Letter of
Transmittal and, if given or made, such information or representation must not
be relied upon as having been authorized. Neither the delivery of this Offer
to Purchase nor any purchase pursuant to the Offer shall, under any
circumstances, create any implication that there has been no change in the
affairs of Purchaser or the Company since the date as of which information is
furnished or the date of this Offer to Purchase.
 
  Purchaser and Parent have filed with the Commission a Tender Offer Statement
on Schedule 14D-1, together with exhibits, pursuant to Rule 14d-3 under the
Exchange Act, furnishing certain additional information with respect to the
Offer. In addition, the Company has filed with the Commission the Schedule
14D-9, together with exhibits, pursuant to Rule 14d-9 under the Exchange Act,
setting forth the recommendations of the Board with respect to the Offer and
the reasons for such recommendations and furnishing certain additional related
information. Such Schedules and any amendments thereto, including exhibits,
may be inspected and copies may be obtained from the Commission in the manner
set forth in Section 7 (except that they will not be available at the regional
offices of the Commission).

                                    ANNEX A
 
          TEXT OF SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW
 
  262 APPRAISAL RIGHTS.--(a) Any stockholder of a corporation of this State
who holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation,
who has otherwise complied with subsection (d) of this section and who has
neither voted in favor of the merger or consolidation nor consented thereto in
writing pursuant to (S) 228 of this title shall be entitled to an appraisal by
the Court of Chancery of the fair value of the stockholder's shares of stock
under the circumstances described in subsections (b) and (c) of this section.
As used in this section, the word "stockholder" means a holder of record stock
in a stock corporation and also a member of record of a nonstock corporation;
the words "stock" and "share" mean and include what is ordinarily meant by
those words and also membership or membership interest of a member of a
nonstock corporation; and the words "depository receipt" mean a receipt or
other instrument issued by a depository representing an interest in one or
more shares, or fractions thereof, solely of stock of a corporation, which
stock is deposited with the depository.
 
  (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to
be effected pursuant to (S) 251 (other than a merger effected pursuant to (S)
251(g) of this title), (S) 252, (S) 254, (S) 257, (S) 258, (S) 263 or (S) 264
of this title:
 
    (1) Provided, however, that no appraisal rights under this section shall
  be available for the shares of any class or series of stock, which stock,
  or depository receipts in respect thereof, at the record date fixed to
  determine the stockholders entitled to receive notice of and to vote at the
  meeting of stockholders to act upon the agreement of merger or
  consolidation, were either (i) listed on a national securities exchange or
  designated as a national market system security on an interdealer quotation
  system by the National Association of Securities Dealers, Inc. or (ii) held
  of record by more than 2,000 holders; and further provided that no
  appraisal rights shall be available for any shares of stock of the
  constituent corporation surviving a merger if the merger did not require
  for its approval the vote of the stockholders of the surviving corporation
  as provided in subsection (t) of (S) 251 of this title.
 
    (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
  under this section shall be available for the shares of any class or series
  of stock of a constituent corporation if the holders thereof are required
  by the terms of an agreement of merger or consolidation pursuant to (S)(S)
  251, 252, 254, 257, 258, 263 and 264 of this title, to accept for such
  stock anything except:
 
      a. Shares of stock of the corporation surviving or resulting from
    such merger or consolidation, or depository receipts in respect
    thereof;
 
      b. Shares of stock of any other corporation, or depository receipts
    in respect thereof, which shares of stock (or depository receipts in
    respect thereof) or depository receipts at the effective date of the
    merger or consolidation will be either listed on a national securities
    exchange or designated as a national market system security on an
    interdealer quotation system by the National Association of Securities
    Dealers, Inc. or held of record by more than 2,000 holders;
 
      c. Cash in lieu of fractional shares or fractional depository
    receipts described in the foregoing subparagraphs a. and b. of this
    paragraph; or
 
      d. Any combination of the shares of stock, depository receipts and
    cash in lieu of fractional shares or fractional depository receipts
    described in the foregoing subparagraphs a., b. and c. of this
    paragraph.
 
    (3) In the event all of the stock of a subsidiary Delaware corporation
  party to a merger effected under (S) 253 of this title is not owned by the
  parent corporation immediately prior to the merger, appraisal rights shall
  be available for the shares of the subsidiary Delaware corporation.
 
                                      A-1

  (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets
of the corporation. If the certificate of incorporation contains such a
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.
 
  (d) Appraisal rights shall be perfected as follows:
 
    (1) If a proposed merger or consolidation for which appraisal rights are
  provided under this section is to be submitted for approval at a meeting of
  stockholders, the corporation, not less than 20 days prior to the meeting,
  shall notify each of its stockholders who was such on the record date for
  such meeting with respect to shares for which appraisal rights are
  available pursuant to subsections (b) or (c) hereof that appraisal rights
  are available for any or all of the shares of the constituent corporations,
  and shall include in such notice a copy of this section. Each stockholder
  electing to demand the appraisal of his shares shall deliver to the
  corporation, before the taking of the vote on the merger or consolidation,
  a written demand for appraisal of his shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of his shares. A proxy or vote against the merger or
  consolidation shall not constitute such a demand. A stockholder electing to
  take such action must do so by a separate written demand as herein
  provided. Within 10 days after the effective date of such merger or
  consolidation, the surviving or resulting corporation shall notify each
  stockholder of each constituent corporation who has complied with this
  subsection and has not voted in favor of or consented to the merger or
  consolidation of the date that the merger or consolidation has become
  effective; or
 
    (2) If the merger or consolidation was approved pursuant to (S) 228 or
  (S) 253 of this title, each constituent corporation, either before the
  effective date of the merger or consolidation or within ten days
  thereafter, shall notify each of the holders of any class or series of
  stock of such constituent corporation who are entitled to appraisal rights
  of the approval of the merger or consolidation and that appraisal rights
  are available for any or all shares of such class or series of stock of
  such constituent corporation, and shall include in such notice a copy of
  this section; provided that, if the notice is given on or after the
  effective date of the merger or consolidation, such notice shall be given
  by the surviving or resulting corporation to all such holders of any class
  or series of stock of a constituent corporation that are entitled to
  appraisal rights. Such notice may, and, if given on or after the effective
  date of the merger or consolidation, shall, also notify such stockholders
  of the effective date of the merger or consolidation. Any stockholder
  entitled to appraisal rights may, within 20 days after the date of mailing
  of such notice, demand in writing from the surviving or resulting
  corporation the appraisal of such holder's shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of such holder's shares. If such notice did not notify
  stockholders of the effective date of the merger or consolidation, either
  (i) each such constituent corporation shall send a second notice before the
  effective date of the merger or consolidation notifying each of the holders
  of any class or series of stock of such constituent corporation that are
  entitled to appraisal rights of the effective date of the merger or
  consolidation or (ii) the surviving or resulting corporation shall send
  such a second notice to all such holders on or within 10 days after such
  effective date; provided, however, that if such second notice is sent more
  than 20 days following the sending of the first notice, such second notice
  need only be sent to each stockholder who is entitled to appraisal rights
  and who has demanded appraisal of such holder's shares in accordance with
  this subsection. An affidavit of the secretary or assistant secretary or of
  the transfer agent of the corporation that is required to give either
  notice that such notice has been given shall, in the absence of fraud, be
  prima facie evidence of the facts stated therein. For purposes of
  determining the stockholders entitled to receive either notice, each
  constituent corporation may fix, in advance, a record date that shall be
  not more than 10 days prior to the date the notice is given, provided, that
  if the notice is given on or after the effective date of the merger or

  date is fixed and the notice is given prior to the effective date, the

  (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied
with subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger
or consolidation, any stockholder shall have the right to withdraw his demand
for appraisal and to accept the terms offered upon the merger or
consolidation. Within 120 days after the effective date of the merger or
consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which
demands for appraisal have been received and the aggregate number of holders
of such shares. Such written statement shall be mailed to the stockholder
within 10 days after his written request for such a statement is received by
the surviving or resulting corporation or within 10 days after expiration of
the period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.
 
  (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by I or more
publications at least I week before the (lay of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.
 
  (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates
to submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as
to such stockholder.
 
  (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court
may, in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on
the list filed by the surviving or resulting corporation pursuant to
subsection (1) of this section and who has submitted his certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that he is not entitled to
appraisal rights under this section.
 
  (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and the case of holders of
shares represented by certificates upon the surrender to the corporation of
the certificates representing such stock. The Court's decree may be enforced
as other decrees in the Court of
 
                                      A-3
<PAGE>
 
Chancery may be enforced, whether such surviving or resulting corporation be a
corporation of this State or of any state.
 
  (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
  (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection
(d) of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation);
provided, however, that if no petition for an appraisal shall be filed within
the time provided in subsection (e) of this section, or if such stockholder
shall deliver to the surviving or resulting corporation a written withdrawal
of his demand for an appraisal and an acceptance of the merger or
consolidation, either within 60 days after the effective date of the merger or
consolidation as provided in subsection (e) of this section or thereafter with
the written approval of the corporation, then the right of such stockholder to
an appraisal shall cease. Notwithstanding the foregoing, no appraisal
proceeding in the Court of Chancery shall be dismissed as to any stockholder
without the approval of the Court, and such approval may be conditioned upon
such terms as the Court deems just.
 
  (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation. (Last amended by Ch. 120, L.
'97, eff. 7-1-97.)

Ladies and Gentlemen:
 
  The undersigned hereby tenders to Tiger Acquisition Corporation, a Delaware
corporation ("Purchaser"), which is a newly-formed, wholly-owned subsidiary of
International Technology Corporation, a Delaware corporation doing business as
The IT Group, Inc. ("Parent"), the above-described shares of common stock, par
value $.001 per share (the "Common Stock"), of Fluor Daniel GTI, Inc., a
Delaware corporation (the "Company"), pursuant to Purchaser's offer to
purchase all of the issued and outstanding shares (the "Shares") of the
Company's Common Stock upon the terms and subject to the conditions set forth
in the Offer to Purchase dated November 3, 1998 (the "Offer to Purchase"),
receipt of which is hereby acknowledged, and in this Letter of Transmittal
(which, together with the Offer to Purchase, constitute the "Offer"), at the
purchase price of $8.25 per Share, net to each tendering stockholder in cash,
without interest (the "Offer Price").
 
  Subject to, and effective upon, acceptance for payment of the Shares
tendered herewith in accordance with the terms and subject to the conditions
of the Offer, the undersigned hereby sells, and transfers to, upon the order
of Purchaser, all right, title and interest in and to all the Shares that are
being tendered hereby and irrevocably constitutes and appoints the Depositary
the true and lawful agent and attorney-in-fact of the undersigned with respect
to such Shares with full power of substitution (such power of attorney being
deemed to be an irrevocable power coupled with an interest), to (a) deliver
certificates for such Shares, or transfer ownership of such Shares (and any
such other Shares or securities) on the account books maintained by the Book-
Entry Transfer Facility, together in either such case with all accompanying
evidences of transfer and authenticity, to or upon the order of Purchaser, (b)
present such Shares for transfer on the books of the Company and (c) receive
all benefits and otherwise exercise all rights of beneficial ownership of such
Shares, all in accordance with the terms of the Offer.
 
  The undersigned hereby irrevocably appoints each designee of Purchaser as
the attorney-in-fact and proxy of the undersigned, each with full power of
substitution, to vote in such manner as each such attorney and proxy or his
substitute shall in his sole discretion deem proper, and otherwise act
(including pursuant to written consent) with respect to all the Shares
tendered hereby which have been accepted for payment by Purchaser prior to the
time of such vote or action, which the undersigned is entitled to vote at any
meeting of stockholders (whether annual or special and whether or not an
adjourned meeting) of the Company, or consent in lieu of any such meeting, or
otherwise. This proxy is coupled with an interest in the Company and in the
Shares and is irrevocable and is granted in consideration of the deposit by
Purchaser with the Depositary of the Offer Price for such Shares in accordance
with the terms of the Offer. Purchaser's acceptance for payment of the Shares
shall revoke all proxies granted by the undersigned at any time with respect
to such Shares and no subsequent proxies will be given (and if given will be
deemed not to be effective) with respect thereto by the undersigned.
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Shares tendered
hereby and that, when the same are accepted for payment by Purchaser,
Purchaser will acquire good and unencumbered title thereto, free and clear of
all liens, restrictions, charges and encumbrances and the same will not be
subject to any adverse claim. The undersigned, upon request, will execute and
deliver any additional documents deemed by the Depositary or Purchaser to be
necessary or desirable to complete the sale, assignment and transfer of the
Shares tendered hereby.
 
  All authority herein conferred or agreed to be conferred in this Letter of
Transmittal shall not be affected by, and shall survive, the death or
incapacity of the undersigned and any obligation of the undersigned hereunder
shall be binding upon the successors, assigns, heirs, executors,
administrators and legal representatives of the undersigned. Except as stated
in the Offer to Purchase, this tender is irrevocable.
 
  The undersigned understands that tenders of Shares pursuant to any one of
the procedures described in Section 2 of the Offer to Purchase and in the
instructions hereto will constitute a binding agreement between the
undersigned and Purchaser upon the terms and subject to the conditions of the
Offer.

joint owners, all such owners must sign this Letter of Transmittal.
 
  If any tendered Shares are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of

  If this Letter of Transmittal or any certificates or stock powers are signed
by a trustee, executor, administrator, guardian, attorney-in-fact, officer of

taxes or exemption therefrom is submitted.
 
  EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.

signer of this Letter of Transmittal or if a check is to be sent or such
certificates are to be returned to someone other than the signer of this
Letter of Transmittal or to an address other than that shown above, the
appropriate boxes on this Letter of Transmittal should be completed.
Stockholders tendering Shares by book-entry transfer may request that Shares
not purchased be credited to such account maintained at the Book-Entry
Transfer Facility. If no such instructions are given, such Shares not
purchased will be returned by crediting the account at the Book-Entry Transfer
Facility.

<PAGE>
 
  9. Waiver of Conditions. Subject to the terms of the Merger Agreement (as
defined in the Offer to Purchase), the conditions of the Offer may be waived
by Purchaser, in whole or in part, at any time and from time to time in the
Purchaser's sole discretion, in the case of any Shares tendered.
 
  10. Substitute Form W-9. The tendering stockholder is required to provide
the Depositary with a correct Taxpayer Identification Number ("TIN") on
Substitute Form W-9 which is provided under "Important Tax Information" below,
and to certify whether the stockholder is subject to backup withholding of
Federal income tax. If a tendering stockholder is subject to backup
withholding, the stockholder must cross out item (2) of the Certification box
of the Substitute Form W-9. Failure to provide the information on the
Substitute Form W-9 may subject the tendering stockholder to 31% Federal
income tax withholding on the payment of all reportable payments made to such
stockholder. If the tendering stockholder has not been issued a TIN and has
applied for a number or intends to apply for a number in the near future, he
or she should write "Applied For" in the space provided for the TIN in Part I,
and sign and date the Substitute Form W-9. If "Applied For" is written in Part
I, the Depositary will withhold 31% on all payments of the purchase price
until a TIN is provided to the Depositary.
 
  11. Lost, Destroyed or Stolen Certificates. If any certificate(s)
representing Shares has been lost, destroyed or stolen, the stockholder should
promptly notify the Depositary. The stockholder will then be instructed as to
the steps that must be taken in order to replace the certificate(s). This
Letter of Transmittal and related documents cannot be processed until the
procedures for replacing lost or destroyed certificates have been followed.
 
  IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE THEREOF), TOGETHER
WITH CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER
REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE DEPOSITARY, OR THE NOTICE OF
GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY, PRIOR TO THE
EXPIRATION DATE.
 
                           IMPORTANT TAX INFORMATION
 
  Under Federal income tax law, a stockholder whose tendered Shares are
accepted for payment is required to provide the Depositary with such
stockholder's correct TIN on Substitute Form W-9 below. If such stockholder is
an individual, the TIN is his or her social security number. If a tendering
stockholder is subject to backup withholding, he or she must cross out item
(2) of the Certification box on the Substitute Form W-9. Failure to provide
the requisite information on the Substitute Form W-9 may cause the tendering
stockholder to be subject to backup withholding. In addition, failure to
provide the correct information, including the correct TIN, on the Substitute
Form W-9 may cause the stockholder to be subject to various penalties,
including a $50 penalty for each such failure, unless such failure is due to
reasonable cause and not willful neglect.
 
  Certain stockholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, that stockholder must submit a statement, signed under penalties of
perjury, attesting to that individual's exempt status. Such statements may be
obtained from the Depositary. Exempt stockholders, other than foreign
individuals, should furnish their TIN, write "Exempt" on the face of the
Substitute Form W-9 below and sign, date and return the Substitute Form W-9 to
the Depositary. See the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional instructions.
 
  If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the stockholder. Backup withholding is not an additional
tax. Rather, the tax owed by persons subject to backup withholding will be
reduced by the amount of tax withheld. If withholding results in an
overpayment of taxes, a refund may be obtained.
 
                                       8

PURPOSE OF SUBSTITUTE FORM W-9
 
  To prevent backup withholding on payments that are made to a stockholder
with respect to Shares purchased pursuant to the Offer, the stockholder is
required to (1) notify the Depositary of his or her correct TIN by completing
the form below certifying that the TIN provided on the Substitute Form W-9 is
correct and (2) certify that he or she is not subject to backup withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
  The stockholder is required to give the Depositary the social security
number or employer identification number of the record owner of the Shares. If
the Shares are in more than one name or are not in the name of the actual
owner, consult the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional guidelines on
which number to report. If the tendering stockholder has not been issued a TIN
and has applied for a number or intends to apply for a number in the near
future, the stockholder should write "Applied For" in the space provided for
in the TIN in Part I, and sign and date the Substitute Form W-9. If "Applied
For" is written in Part I, the Depositary will withhold 31% on all payments of
the purchase price until a TIN is provided to the Depositary.

                               because I have not been notified by the IRS
                               that I am subject to backup withholding as a
                               result of a failure to report all interest or
                               dividends, or the IRS has notified me that I
                               am no longer subject to backup withholding.

                           dividends on your tax return. However, if after
                           being notified by the IRS that you were subject to

To Brokers, Dealers, Commercial Banks,
Trust Companies And Other Nominees:
 
  We have been engaged to act as Information Agent in connection with the

which is a newly-formed, wholly-owned subsidiary of International Technology
Corporation, a Delaware corporation doing business as The IT Group, Inc.
("Parent"), to purchase all of the issued and outstanding shares of common

Delaware corporation (the "Company"), at $8.25 per Share, net to each
tendering stockholder in cash, without interest, upon the terms and subject to
the conditions set forth in Purchaser's Offer to Purchase dated November 3,
1998 (the "Offer to Purchase") and the related Letter of Transmittal (which,
together with the Offer to Purchase, constitute the "Offer").
 
  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (A) THE SATISFACTION OR
     WAIVER OF CERTAIN CONDITIONS TO THE OBLIGATIONS OF PURCHASER AND THE
     COMPANY TO CONSUMMATE THE OFFER, INCLUDING RECEIPT BY PURCHASER AND 
      THE COMPANY OF CERTAIN GOVERNMENTAL AND REGULATORY APPROVALS, AND 
        (B) ON THE "MINIMUM SHARE NUMBER" (AS DEFINED IN THE OFFER TO 
                           PURCHASE) BEING TENDERED.
 
  For your information and for forwarding to your clients for whom you hold
Shares registered in your name or in the name of your nominee, or who hold
Shares registered in their own names, we are enclosing the following
documents:
 
    1. Offer to Purchase dated November 3, 1998;
 
    2. Letter of Transmittal to be used by stockholders of the Company in
  accepting the Offer and tendering Shares;
 
    3. Letter to Clients which may be sent to your clients for whose account
  you hold Shares in your name or in the name of your nominees, with space
  provided for obtaining such clients' instructions with regard to the Offer;
 
    4. Notice of Guaranteed Delivery to be used to accept the Offer if
  certificates for Shares are not immediately available or time will not
  permit all required documents to reach the Depositary prior to the
  Expiration Date (as defined in the Offer to Purchase) or if the procedures
  for book-entry transfer, as set forth in the Offer to Purchase, cannot be
  completed in a timely manner;

<PAGE>
 
    5. Guidelines for certification of taxpayer identification number on
  Substitute Form W-9; and
 
    6. Return envelope addressed to BankBoston, N.A., as Depositary.
 
  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension
or amendment), Purchaser will accept for payment and pay for all of the Shares
validly tendered pursuant to the Offer prior to the Expiration Date and not
withdrawn in accordance with the provisions set forth in the Offer to
Purchase. The term "Expiration Date" shall mean 12:00 Midnight, New York City
time, on Wednesday, December 2, 1998, unless and until Parent, in its sole
discretion (subject to restrictions set forth in the Offer to Purchase), shall
from time to time have extended the period of time during which the Offer is
open, in which event the term "Expiration Date" shall mean the latest time and
date at which the Offer, as so extended by Parent, shall expire.
 
  Parent reserves the right, in its sole discretion (but subject to the terms
and conditions of the Offer to Purchase), to (i) from time to time extend the
Offer for a period not to exceed ten (10) business days (as defined in the
Offer to Purchase) after the previously scheduled Expiration Date of the Offer
if at any scheduled Expiration Date any of the conditions to the Offer has not
been satisfied or waived, (ii) extend the Offer for any period required by any
rule, regulation, interpretation or position of the Securities and Exchanges
Commission or the Staff thereof applicable to the Offer and (iii) extend the
Offer for any reason on up to two (2) occasions in each case for a period of
not more than five (5) business days (as defined in the Offer to Purchase)
beyond the latest Expiration Date that would be otherwise permitted under
clause (i) or (ii) of this sentence if on such Expiration Date there shall
have been tendered more than the number of Shares sufficient to satisfy the
Minimum Condition (as defined in the Offer to Purchase) but less than 90% of
the Shares, provided the Purchaser agrees to permanently waive certain
conditions, as set forth in the Offer to Purchase.
 
  If all of the conditions to the Offer are not satisfied on any scheduled
Expiration Date of the Offer then, provided that all such conditions are
reasonably capable of being satisfied prior to December 31, 1998, Parent shall
extend the Offer from time to time (each such individual extension not to
exceed ten (10) business days) until such conditions are satisfied or waived,
provided that Parent shall not be required to extend the Offer beyond December
31, 1998.
 
  Any extension by Parent shall be effective by giving oral or written notice
of such extension to the Depositary. During any such extension, all Shares
previously tendered and not withdrawn will remain subject to the Offer,
subject to the rights of a tendering stockholder to withdraw such
stockholder's Shares. If Parent extends the Offer, or if Purchaser (whether
before or after its acceptance for payment of Shares) is delayed in its
payment for Shares or is unable to pay for Shares pursuant to the Offer for
any reason, then, without prejudice to Purchaser's rights under the Offer, the
Depositary may retain tendered Shares on behalf of Purchaser, and such Shares
may not be withdrawn except to the extent tendering stockholders are entitled
to withdrawal rights as described in the Offer to Purchase. However, the
ability of Purchaser to delay payment for Shares that Purchaser has accepted
for payment is limited by Rule 14e-1(c) under the Exchange Act.
 
  In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after either (a)(i) a properly completed and duly executed
Letter of Transmittal (or facsimile thereof), together with any required
signature guarantees, or an Agent's Message (as defined in the Offer to
Purchase) in connection with a book-entry delivery of Shares and any other
required documents, has been timely received by the Depositary at one of its
addresses set forth on the back cover of the Offer to Purchase and (ii) either
Share certificates for tendered Shares have been timely received by the
Depositary at one of such addresses or such Shares have been timely delivered
pursuant to the procedure for book-entry transfer set forth in the Offer to
Purchase (and a Book-Entry Confirmation (as defined in the Offer to Purchase)
timely received by the Depositary) or (b)  the tendering stockholder has
complied with the guaranteed delivery procedures set forth in the Offer to
Purchase.
 
  Purchaser will not pay any fees or commissions to any broker or dealer or
other person (other than the Depositary and the Information Agent as described
in the Offer to Purchase) in connection with the solicitation of tenders of
Shares pursuant to the Offer. However, Purchaser will upon request, reimburse
you for customary mailing and handling expenses incurred by you in forwarding
the enclosed materials to your clients.

To Our Clients:
 
  Enclosed for your consideration is an Offer to Purchase dated November 3,
1998 (the "Offer to Purchase") and the related Letter of Transmittal (which,
together with the Offer to Purchase, constitute the "Offer") relating to an
offer by Tiger Acquisition Corporation, a Delaware corporation ("Purchaser"),
which is a newly-formed, wholly-owned subsidiary of International Technology
Corporation, a Delaware corporation doing business as The IT Group, Inc.
("Parent"), to purchase all of the issued and outstanding shares of common
stock, par value $.001 per share (the "Shares"), of Fluor Daniel GTI, Inc., a
Delaware corporation (the "Company"), at a purchase price of $8.25 per Share,
net to each tendering stockholder in cash, without interest, upon the terms
and subject to the conditions set forth in the Offer (the "Offer Price"). We
are the holder of record of Shares held by us for your account. The Letter of
Transmittal is furnished to you for your information only and cannot be used
by you to tender Shares. A tender of Shares can be made only by us as the
holder of record of your Shares and pursuant to your instructions.
 
  We request instructions as to whether you wish to tender any or all of the
Shares held by us for your account, pursuant to the terms and conditions set
forth in the Offer.
 
  Your attention is directed to the following:
 
    1. The Offer Price is $8.25 per Share, net to each tendering stockholder
  in cash, without interest.
 
    2. The Offer is being made for all of the Shares.
 
    3. The Offer is being made pursuant to the terms of an Agreement and Plan
  of Merger, dated as of October 27, 1998 (the "Merger Agreement"), by and
  among the Company, Purchaser, Parent and Fluor Daniel, Inc., a California
  corporation. The Merger Agreement provides, among other things, for the
  commencement of the Offer by Purchaser, and further provides that,
  following the purchase of Shares pursuant to the Offer and promptly after
  the satisfaction or, if permissible, waiver of certain other conditions,
  Purchaser will be merged with and into the Company (the "Merger"). The
  Company will continue as the surviving corporation after the Merger.
 
    At the effective time of the Merger (the "Effective Time"), each issued
  and outstanding Share (other than Shares held by Parent, Purchaser or any
  other direct or indirect subsidiary of Parent or Shares that are owned by
  the Company or any direct or indirect subsidiary of the Company, which will
  be canceled and retired without any payment with respect thereto, or Shares
  (the "Dissenting Shares") with respect to which the holder properly
  exercises such holder's appraisal rights in accordance with the Delaware
  General Corporation Law (collectively, the "Excluded Shares")) shall be
  converted into, and become exchangeable for the Offer Price, and the Offer
  Price multiplied by the number of such Shares is the "Merger
  Consideration."
<PAGE>
 
    At the Effective Time, all Shares, other than Dissenting Shares, shall be
  canceled and retired and shall cease to exist, and each certificate
  formerly representing any of such Shares (other than any Excluded Shares)
  shall thereafter represent only the right to receive the Merger
  Consideration.
 
    4. The Company's Board of Directors, acting on the unanimous
  recommendation of a special committee of independent directors of the
  Company (the "Special Committee"), has unanimously determined that the
  Merger Agreement and the transactions contemplated thereby, including the
  Offer and the Merger, are fair to and in the best interests of the
  stockholders of the Company, has unanimously approved the Merger Agreement
  and the transactions contemplated thereby, including the Offer and the
  Merger, and recommends that the stockholders accept the Offer and tender
  their Shares thereunder.
 
    BT Alex. Brown Incorporated ("BT Alex. Brown"), financial advisor to the
  Company, has delivered a written opinion to the Special Committee and the
  Company's Board of Directors, dated as of the date of the Merger Agreement
  (the "Opinion"), to the effect that, as of that date, the consideration to
  be received by the stockholders of the Company pursuant to the Merger
  Agreement is fair from a financial point of view to such stockholders. The
  full text of the Opinion is contained in the Company's
  solicitation/recommendation statement on Schedule 14D-9 filed with the
  Securities and Exchange Commission in connection with the Offer.
  Stockholders are urged to read the Opinion carefully and in its entirety
  for assumptions made, matters considered and limits of the review of BT
  Alex. Brown.
 
    5. The Offer and withdrawal rights will expire at 12:00 Midnight, New
  York City time, on Wednesday, December 2, 1998, unless extended.
 
    6. The Offer is conditioned upon, among other things, there being validly
  tendered prior to the expiration date and not withdrawn at least the
  Minimum Share Number (as defined in the Offer to Purchase) of Shares. The
  Offer is also subject to, among other things, the satisfaction or waiver of
  certain conditions to the obligations of Parent, Purchaser and the Company
  to consummate the Offer, including receipt by Purchaser and the Company of
  certain governmental and regulatory approvals.
 
    7. Stockholders who tender Shares will not be obligated to pay brokerage
  commissions or, except as set forth in Instruction 6 of the Letter of
  Transmittal, transfer taxes on the purchase of Shares by Purchaser pursuant
  to the Offer.
 
  If you wish to have us tender any or all of your Shares, please complete,
sign and return the form set forth below. Your instructions to us should be
forwarded in ample time to permit us to submit a tender on your behalf prior

 offer to sell Shares (as defined below). The Offer (as defined below) is 
  made solely by the Offer to Purchase, dated November 3, 1998, and the 
   related Letter of Transmittal, and is being made to all holders of 
    Shares. The Offer is not being made to (nor will tenders be accepted 
     from or on behalf of) holders of Shares in any jurisdiction in 
      which the making of the Offer or the acceptance thereof would 
       not be in compliance with the securities, blue sky or other 
        laws of such jurisdiction. Purchaser (as defined below) 
         may, in its discretion, however, take such action as it 
          may deem necessary to make the Offer in any jurisdiction 
           and extend the Offer to holders of Shares in such 
            jurisdiction. In any jurisdiction where the securities, 
             blue sky or other laws require the Offer to be made 
              by a licensed broker or dealer, the Offer shall be 
               deemed to be made on behalf of Purchaser by one 
                or more registered brokers or dealers licensed 
                    under the laws of such jurisdiction.

                            Fluor Daniel GTI, Inc.

                         Tiger Acquisition Corporation
                         a wholly-owned subsidiary of
                              The IT Group, Inc.

    Tiger Acquisition Corporation, a Delaware corporation ("Purchaser"), which
is a newly-formed, wholly-owned subsidiary of International Technology
Corporation, a Delaware corporation doing business as The IT Group, Inc.
("Parent"), is offering to purchase all of the issued and outstanding shares of
common stock, par value $.001 per share (the "Shares"), of Fluor Daniel GTI,
Inc., a Delaware corporation (the "Company"), at a price of $8.25 per Share, net
to each tendering stockholder in cash, without interest (the "Offer Price"),
upon the terms and subject to the conditions set forth in the Offer to Purchase
dated November 3, 1998 (the "Offer to Purchase") and in the related Letter of
Transmittal (which, together with the Offer to Purchase, constitute the
"Offer"). The Offer is being made pursuant to the terms of an Agreement and Plan
of Merger (the "Merger Agreement"), dated as of October 27, 1998, by and among
the Company, Purchaser, Parent and Fluor Daniel, Inc., a California corporation.
The Merger Agreement provides, among other things, for the commencement of the
Offer by Purchaser, and further provides that, following the purchase of Shares
pursuant to the Offer and promptly after the satisfaction or, if permissible,
waiver of certain other conditions, Purchaser will be merged with and into the
Company (the "Merger"). The Company will continue as the surviving corporation
after the Merger.

    ------------------------------------------------------------------------
    THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK
    CITY TIME, ON WEDNESDAY, DECEMBER 2, 1998, UNLESS THE OFFER IS EXTENDED.
    ------------------------------------------------------------------------

    At the effective time of the Merger (the "Effective Time"), each Share
(other than Shares held by Parent, Purchaser or any other direct or indirect
subsidiary of Parent or Shares that are owned by the Company or any direct or
indirect subsidiary of the Company, which will be canceled and retired without
any payment with respect thereto, or Shares (the "Dissenting Shares") with
respect to which the holder properly exercises such holder's appraisal rights in
accordance with the Delaware General Corporation Law (collectively, the
"Excluded Shares")), shall be converted into and become exchangeable for the
Offer Price, and the Offer Price multiplied by the number of such Shares is the
"Merger Consideration."
    At the Effective Time, all Shares, other than Dissenting Shares, shall be 
canceled and retired and shall cease to exist, and each certificate formerly
representing any of such Shares (other than any Excluded Shares) shall
thereafter represent only the right to receive the Merger Consideration.
    THE BOARD OF DIRECTORS OF THE COMPANY, ACTING ON THE UNANIMOUS 
RECOMMENDATION OF A SPECIAL COMMITTEE OF INDEPENDENT DIRECTORS (THE "SPECIAL 
COMMITTEE"), HAS UNANIMOUSLY DETERMINED THAT THE MERGER AGREEMENT AND THE 
TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER AND THE MERGER, ARE FAIR 
TO AND IN THE BEST INTERESTS OF THE STOCKHOLDERS OF THE COMPANY, HAS UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY, 
INCLUDING THE OFFER AND THE MERGER, AND RECOMMENDS THAT THE STOCKHOLDERS ACCEPT 
THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER.
    The Offer is conditioned upon, among other things, there being validly 
tendered prior to the Expiration Date and not withdrawn the Minimum Share Number
(as defined in the Offer to Purchase) of Shares. The Offer is also conditioned 
on the satisfaction or waiver of certain other conditions, including receipt by 
Purchaser and the Company of certain governmental and regulatory approvals. Any 
determination concerning the satisfaction of such terms and conditions will be 
made by Purchaser in its good faith judgment and such determination will be 
final and binding on all tendering stockholders.
    Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension or 
amendment), Purchaser will accept for payment and pay for all of the Shares 
validly tendered pursuant to the Offer prior to the Expiration Date and not 
withdrawn in accordance with the provisions set forth in the Offer to Purchase. 
The term "Expiration Date" shall mean 12:00 Midnight, New York City time, on 
Wednesday, December 2, 1998, unless and until Parent, in its sole discretion 
(but subject to restrictions contained in the Merger Agreement), shall from time
to time have extended the period of time during which the Offer is open, in 
which event the term "Expiration Date" shall mean the latest time and date at 
which the Offer, as so extended by Parent, shall expire.
    Parent reserves the right, in its sole discretion (but subject to the terms 
and conditions of the Offer to Purchase), to (i) from time to time extend the 
Offer for a period not to exceed ten (10) business days (as defined in the Offer
to Purchase) after the previously scheduled Expiration Date of the Offer if at 
any scheduled Expiration Date any of the conditions to the Offer has not been 
satisfied or waived, (ii) extend the Offer for any period required by any rule, 
regulation, interpretation or position of the Securities and Exchange Commission
or the Staff thereof applicable to the Offer and (iii) extend the Offer for any 
reason on up to two (2) occasions in each case for a period of not more than 
five (5) business days (as defined in the Offer to Purchase) beyond the latest 
Expiration Date that would be otherwise permitted under clause (i) or (ii) of 
this sentence if on such Expiration Date there shall have been tendered more 
than the number of Shares sufficient to satisfy the Minimum Condition (as 
defined in the Offer to Purchase) but less than 90% of the Shares, provided the 
Purchaser agrees to permanently waive certain conditions, as set forth in the 
Offer to Purchase.
    If all of the conditions to the Offer are not satisfied on any scheduled 
Expiration Date of the Offer then, provided that all such conditions are 
reasonably capable of being satisfied prior to December 31, 1998, Parent shall 
extend the Offer from time to time (each such individual extension not to 
exceed ten (10) business days) until such conditions are satisfied or waived, 
provided that Parent shall not be required to extend the Offer beyond December 
31, 1998.
    Any extension by Parent shall be effective by giving oral or written notice 
of such extension to BankBoston, N.A., as Depositary (the "Depositary"). During 
any such extension, all Shares previously tendered and not withdrawn will remain
subject to the Offer, subject to the rights of a tendering stockholder to
withdraw such stockholder's Shares. If Parent extends the Offer, or if Purchaser
(whether before or after its acceptance for payment of Shares) is delayed in its
payment for Shares or is unable to pay for Shares pursuant to the Offer for any
reason, then, without prejudice to Purchaser's rights under the Offer, the
Depositary may retain tendered Shares on behalf of Purchaser, and such Shares
may not be withdrawn except to the extent tendering stockholders are entitled to
withdrawal rights as described in the Offer to Purchase. However, the ability of
Purchaser to delay payment for Shares that Purchaser has accepted for payment is
limited by Rule 14e-1(c) under the Securities Exchange Act of 1934, as amended
(the "Exchange Act").
    In all cases, payment for Shares accepted for payment pursuant to the Offer 
will be made only after either (a)(i) a properly completed and duly executed 
Letter of Transmittal (or facsimile thereof), together with any required 
signature guarantees, or an Agent's Message (as defined in the Offer to 
Purchase) in connection with a book-entry delivery of Shares and any other 
required documents, has been timely received by the Depositary at one of its 
addresses set forth on the back cover of the Offer to Purchase and (ii) either 
Share certificates for tendered Shares have been timely received by the 
Depositary at one of such addresses or such Shares have been timely delivered 
pursuant to the procedure for book-entry transfer set forth in the Offer to 
Purchase (and a Book-Entry Confirmation (as defined in the Offer to Purchase) 
timely received by the Depositary) or (b) the tendering stockholder has complied
with the guaranteed delivery procedures set forth in the Offer to Purchase.
    Pursuant to the Merger Agreement, Parent may make any changes in the terms 
and conditions of the Offer, provided that, unless previously approved by the 
Special Committee and the Company's Board of Directors in writing, Parent may 
not (i) decrease the Offer Price, (ii) change the form of consideration payable 
in the Offer, (iii) reduce the maximum number of Shares to be purchased in the 
Offer, (iv) amend the conditions to the Offer set forth in the Merger Agreement 
to broaden their scope, (v) impose additional conditions of the Offer or amend 
any other term of the Offer in any manner adverse to holders of Shares or 
extend the Offer if all of the conditions to the Offer are satisfied or waived, 
or (vi) amend the Minimum Condition.
    Tenders of Shares made pursuant to the Offer will be irrevocable, except
that Shares tendered may be withdrawn at any time prior to the Expiration Date,
and, unless theretofore accepted for payment and paid for as provided herein,
may also be withdrawn at any time on or after January 2, 1999. For a withdrawal
to be effective, a written, telegraphic or facsimile transmission notice of
withdrawal must be timely received by the Depositary at one of its addresses set
forth on the back cover of the Offer to Purchase. Any notice of withdrawal must
specify the name of the person who tendered the Shares to be withdrawn, the
number of Shares to be withdrawn and the name of the registered holder of the
Shares to be withdrawn as set forth on such Share certificates if different from
the name of the person who tendered such Shares. If Share certificates have been
delivered or otherwise identified to the Depositary, then, prior to the physical
release of such Share certificates, the serial numbers shown on such Share
certificates must be furnished to the Depositary and, unless such Shares have
been tendered by an Eligible Institution (as defined in the Offer to Purchase),
the signatures on the notice of withdrawal must be guaranteed by an Eligible
Institution. If Shares have been delivered pursuant to the procedures for book-
entry transfer set forth in the Offer to Purchase, any notice of withdrawal must
specify the name and number of the account at the Book-Entry Transfer Facility
(as defined in the Offer to Purchase) to be credited with such withdrawn Shares
and otherwise comply with such Book-Entry Transfer Facility's procedures for
withdrawal, in which case a notice of withdrawal will be effective if delivered
to the Depositary by any method of delivery described in the second sentence of
this paragraph. All questions as to the form and validity (including time of
receipt) of notices of withdrawal will be determined by Purchaser in its sole
discretion, and its determination will be final and binding. No withdrawal of
Shares will be deemed to have been properly made until all defects and
irregularities have been cured or waived. Withdrawals of tenders of Shares may
not be rescinded, and any Shares properly withdrawn will thereafter be deemed
not validly tendered for purposes of the Offer. However, withdrawn Shares may be
retendered by following one of the procedures described in the Offer to Purchase
at any time prior to the Expiration Date.
    The Company has provided Purchaser with the Company stockholder list, a 
nonobjecting beneficial owners list, and security position listings for the 
purpose of disseminating the Offer to holders of Shares. The Offer to Purchase 
and the Letter of Transmittal and other material relevant to the Offer will be 
mailed to record holders of Shares and furnished to brokers, dealers, commercial
banks, trust companies and similar persons whose names, or the names of whose 
nominees, appear on the stockholder list or, if applicable, who are listed as 
participants in a clearing agency's security position listing, for subsequent 
transmittal to beneficial owners of Shares.
    The information required to be disclosed by Rule 14d-6(e)(1)(vii) and Rule 
13e-3(e)(1) of the General Rules and Regulations under the Exchange Act is 
contained in the Offer to Purchase and is incorporated herein by reference.
    The Offer to Purchase and the Letter of Transmittal contain important 
information which should be read carefully before any decision is made with 
respect to the Offer.
    Requests for copies of the Offer to Purchase, the Letter of Transmittal and 
other materials related to the Offer may be directed to the Information Agent as
set forth below, and copies will be furnished promptly at Purchaser's expense.

The offer is being made pursuant to the previously announced acquisition
agreement between Tiger Acquisition Corporation, The IT Group, FDGTI and Fluor

wishing to participate in the tender offer will expire at 12:00 midnight, New
York City time, on Wednesday, December 2, 1998 unless Tiger Acquisition
Corporation or The IT Group elects (subject to the terms of their agreement with
FDGTI) to extend the offer.

The Board of Directors of FDGTI, acting on the unanimous recommendation of a 
Special Committee of independent directors, has unanimously determined that the 
offer is fair to and in the best interests of the stockholders of FDGTI.  
FDGTI's Board of Directors unanimously recommends that the FDGTI stockholders 
accept the offer and tender all of their Shares.

leading diversified services company offering a full range of consulting,
facilities management, engineering and construction, and remediation services.

material respects, as though made on and as of such date (other than
representations and warranties in any such Loan Document which expressly speak

and covenants to the Lenders that, after giving effect to this Amendment,
consummation of the GTI Acquisition will constitute a Permitted Acquisition.

Credit Agreement and all other Loan Documents shall remain unchanged and in full
force and effect.

not, except as expressly provided herein, operate as a waiver of any right,
power or remedy of any Lender, any Issuing Bank or the Administrative Agent
under the Credit Agreement or any of the Loan Documents, nor constitute a waiver
of any provision of the Credit Agreement or any of the Loan Documents.

          SECTION 7.  Fees, Costs and Expenses.

and delivered in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed and delivered shall be
deemed an original and all of which taken together shall constitute one and the
same original agreement.

                      ----------------------------------                        
hereby consents to the terms of this Amendment in its capacity as a guarantor
under the Borrower Guaranty to which it is a party and agrees that the terms of
this Amendment shall not affect in any way its obligations and liabilities under
its Borrower Guaranty or any other Loan Document to which it is a party, all of
which obligations and liabilities shall remain in full force and effect and each
of which is hereby reaffirmed.

          SECTION 10.  Governing Law.  This Amendment shall be interpreted, and
                       -------------

     NOW, THEREFORE, in consideration of the premises, and of the

                                   THE OFFER

     1.1.  The Offer.
           --------- 

           (a) Provided that this Agreement shall not have been terminated in
accordance with Article VIII and subject to the conditions set forth in Annex A
(as defined below), as promptly as practicable, but in no event later than five
(5) Business Days after the public announcement of the execution of this
Agreement by the parties, Parent shall commence (within 
<PAGE>
 
the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended
(the "Exchange Act")), the Offer for any and all of the Shares, at the Offer
      ------------    
Price. The parties agree such public announcement shall occur promptly after the
execution and delivery of this Agreement. The obligation of Parent to accept for
payment and to pay for any Shares tendered shall be subject only to (i) the
condition that the FD Shares and at least a majority of issued and outstanding
Shares not owned by FD be validly tendered and not withdrawn (the "Minimum
                                                                   -------
Condition"), and (ii) the other conditions set forth in Annex A hereto ("Annex
- ---------                                                                -----
A"). Parent expressly reserves the right to increase the Offer Price or to make
- -
any other changes in the terms and conditions of the Offer; provided, however,
that, unless previously approved by the Special Committee (the "Special
                                                                -------
Committee") of the Board of Directors (the "Company's Board") and the Company's
- ---------                                   ---------------
Board in writing, no change may be made which (i) decreases the Offer Price,
(ii) changes the form of consideration to be paid in the Offer, (iii) reduces
the maximum number of Shares to be purchased in the Offer, (iv) imposes
conditions to the Offer in addition to those set forth in Annex A, (v) amends
the conditions set forth in Annex A to broaden the scope of such conditions,
(vi) amends any other term of the Offer in a manner adverse to the holders of
the Shares, (vii) extends the Offer except as provided in Section 1.1(b), or
(viii) amends the Minimum Condition. It is agreed that the conditions set forth
in Annex A other than the Minimum Condition are for the sole benefit of Parent
and may be waived by Parent, in whole or in part at any time and from time to
time in its sole discretion, other than the Minimum Condition, as to which prior
written approval of the Special Committee and the Company's Board is required.
The failure by Parent at any time to exercise any of the foregoing rights shall
not be deemed a waiver of any such right and each such right shall be deemed an
ongoing right which may be asserted at any time and from time to time. The
Company agrees that no Shares held by the Company or any of its Subsidiaries (as
defined in Section 9.2) will be tendered in the Offer.

          (b) Subject to the terms and conditions thereof, the Offer shall
expire at midnight, New York City time, on the date that is twenty (20) Business
Days after the date the Offer is commenced (the initial "Expiration Date", and
                                                         ---------------      
any expiration time and date established pursuant to an authorized extension of
the Offer as so extended, also an "Expiration Date"); provided, however, that
                                   ---------------                           
without the consent of the Special Committee and the Company's Board, Parent may
(i) from time to time extend the Offer (each such individual extension not to
exceed 10 Business Days after the previously scheduled Expiration Date), if at
the scheduled Expiration Date of the Offer any of the conditions to the Offer
shall not have been satisfied or waived, until such time as such conditions are
satisfied or waived; (ii) extend the Offer for any period required by any rule,
regulation, interpretation or position of the Securities and Exchange Commission
(the "SEC") or the staff thereof applicable to the Offer; or (iii) extend the
      ---                                                                    
Offer for any reason on up to two occasions in each case for a period of not
more than five (5) Business Days beyond the latest Expiration Date that would
otherwise be permitted under clause (i) or (ii) of this sentence if on such
Expiration Date there shall have been tendered more than the number of Shares
sufficient to satisfy the Minimum Condition but less than 90% of the Shares;
provided, the Purchaser agrees to permanently waive the conditions set forth in
paragraphs (b) and (e) of Annex A.  Parent agrees that if all of the conditions
to the Offer set forth on Annex A are not satisfied on any scheduled Expiration
Date, then if all such conditions are reasonably capable of being satisfied
prior to December 31, 1998, Parent shall extend the Offer from time to time
(each 

                                       2
<PAGE>
 
such individual extension not to exceed 10 Business Days after the previously
scheduled Expiration Date) until such conditions are satisfied or waived;
provided, that Parent shall not be required to extend the Offer beyond December
31, 1998. Subject to the terms and conditions of the Offer and this Agreement,
Parent shall accept for payment, and pay for, all Shares validly tendered and
not withdrawn pursuant to the Offer that Parent becomes obligated to accept for
payment and pay for pursuant to the Offer, as promptly as practicable after the
expiration of the Offer.

          (c) As soon as practicable on the date the Offer is commenced, Parent
shall file with the SEC a Tender Offer Statement on Schedule 14D-1 (together
with all amendments and supplements thereto, and including all exhibits thereto,
the "Schedule 14D-1") with respect to the Offer.  The Schedule 14D-1 shall
     --------------                                                       
contain as an exhibit or incorporate by reference the Offer to Purchase (or
portions thereof) and forms of the related letter of transmittal and summary
advertisement.  Parent and Merger Sub agree that the Schedule 14D-1, the Offer
to Purchase and all amendments or supplements thereto (which together constitute
the "Offer Documents") shall comply in all material respects with the Exchange
     ---------------                                                          
Act and the rules and regulations thereunder and other applicable Laws (as
defined in Section 5.1(i)).  Parent and Merger Sub further agree that the Offer
Documents, on the date first published, sent or given to the Company's
stockholders, shall not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading, except that no representation or warranty is made by
Parent or Merger Sub with respect to information supplied by the Company or any
of its stockholders in writing specifically for inclusion or incorporation by
reference in the Offer Documents.  The Company agrees that the written
information provided by the Company for inclusion or incorporation by reference
in the Offer Documents shall not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading.  Each of Parent, Merger Sub and the Company
agrees promptly to correct any information provided by it for use in the Offer
Documents if and to the extent that such information shall have become false or
misleading in any material respect, and Parent and Merger Sub further agree to
take all steps necessary to cause the Schedule 14D-1 as so corrected to be filed
with the SEC and the other Offer Documents as so corrected to be disseminated to
the Company's stockholders, in each case as and to the extent required by
applicable laws.  The Company and counsel for the Special Committee shall be
given reasonable opportunity to review and comment on the Offer Documents prior
to the filing thereof with the SEC.  Parent agrees to provide the Company and
counsel for the Special Committee in writing with any comments Parent or its
counsel may receive from the SEC or its staff with respect to the Offer
Documents promptly after receipt of such comments.

     1.2.  Company Actions.
           ---------------   

          (a) The Company hereby approves of and consents to the Offer and
represents that the Company's Board, at a meeting duly called and held, has,
subject to the terms and conditions set forth herein, (i) determined that this
Agreement and the transactions contemplated hereby, including the Offer and the
Merger, taken together, are fair to and in the best interests of the Company and
its stockholders (other than Parent and its Affiliates), (ii) approved this

                                       3
<PAGE>
 
Agreement and the transactions contemplated hereby, including the Offer and the
Merger, in all respects and such approval constitutes approval of the Offer,
this Agreement and the Merger for purposes of Section 203 of the Delaware
General Corporation Law (the "DGCL"), and (iii) resolved to recommend that the
                              ----                                            
stockholders of the Company accept the Offer, tender their Shares thereunder to
Parent and approve and adopt this Agreement and the Merger; provided, however,
that such recommendation and approval may be withdrawn, modified or amended to
the extent that the Company's Board determines in good faith, after taking into
consideration the advice of its outside legal counsel, that failure to take such
action is likely to result in a breach of the fiduciary obligations of the
Company's Board under applicable law.  The Company consents to the inclusion of
such recommendation and approval in the Offer Documents.  The Company also
represents that the Company's Board has reviewed the opinion of BT Alex. Brown,
Incorporated, financial advisor to the Company's Board (the "Financial
                                                             ---------
Advisor"), that, as of the date of this Agreement, the consideration to be
- -------
received pursuant to this Agreement is fair to the stockholders of the Company
(other than Parent, FD and their respective Affiliates) from a financial point
of view (the "Fairness Opinion").  The Company has been authorized by the
              ----------------                                           
Financial Advisor to permit, subject to the prior review and consent by the
Financial Advisor (such consent not to be unreasonably withheld), the inclusion
of the Fairness Opinion (or a reference thereto) in the Offer Documents, the
Schedule 14D-9 (as defined below) and the Proxy Statement (as defined below).

          (b) The Company shall file with the SEC, concurrently with or as soon
as practicable following the filing of the Schedule 14D-1, a
Solicitation/Recommendation Statement on Schedule 14D-9 (together with all
amendments and supplements thereto, and including all exhibits thereto, the
"Schedule 14D-9") containing the recommendation described in Section 1.2(a) and
- ---------------                                                                
shall mail the Schedule 14D-9 to the stockholders of the Company to the extent
required by Rule 14d-9 promulgated under the Exchange Act and any other
applicable federal securities laws; provided, however, that if the Company's
Board determines in good faith, after taking into consideration the advice of
its outside legal counsel, that the amendment or withdrawal of such
recommendation is likely to be required in order for its members to comply with
their fiduciary duties under applicable law, then any such amendment or
withdrawal, and any related amendment of the Schedule 14D-9, shall not
constitute a breach of this Agreement.  The Company agrees that the Schedule
14D-9 shall comply in all material respects with the Exchange Act and the rules
and regulations thereunder and other applicable laws.  The Company further
agrees that Schedule 14D-9, on the date first published, sent or given to the
Company's stockholders, shall not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading, except that no representation or
warranty is made by the Company with respect to information supplied by the
Parent or Merger Sub in writing specifically for inclusion or incorporation by
reference in Schedule 14D-9.  Each of the Company, Parent and Merger Sub agrees
promptly to correct any written information provided by it for use in the
Schedule 14D-9 or the Offer Documents if and to the extent that such information
shall have become false or misleading in any material respect, and the Company
further agrees to take all steps necessary to cause the Schedule 14D-9 as so
corrected to be filed with the SEC and be disseminated to the Company's
stockholders, in each case as and to the extent required by applicable federal
securities laws.  Parent and its counsel 

                                       4
<PAGE>
 
shall be given reasonable opportunity to review and comment on the Schedule 14D-
9 prior to the filing thereof with the SEC.

          (c) In connection with the Offer, the Company shall cause its transfer
agent to promptly furnish Parent with such information, including updated lists
of the stockholders of the Company, mailing labels and updated lists of security
positions, and such assistance as Parent or its agents may reasonably request in
communicating the Offer to the record and beneficial holders of Shares.  Subject
to the requirements of applicable law, and except for such steps as are
necessary to disseminate the Offer Documents and any other documents necessary
to consummate the Merger, Parent and Sub and their agents shall hold in
confidence the information contained in any such labels, listings and files,
will use such information only in connection with the Offer and the Merger and,
if this Agreement shall be terminated, will deliver, and will use their
reasonable efforts to cause their agents to deliver, to the Company all copies
and any extracts or summaries from such information then in their possession or
control.

          (d) Solely in connection with the tender and purchase of Shares
pursuant to the Offer and the consummation of the Merger, the Company hereby
waives any and all rights of first refusal it may have with respect to Shares
owned by, or issuable to, any Person, other than rights to repurchase unvested
shares, if any, that may be held by Persons following exercise of employee stock
options.

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

          (a) Immediately following the delivery to the Depositary of Parent's
notice of acceptance of Shares pursuant to the Offer (the "Notice of
                                                           ---------
Acceptance"), if the Minimum Condition has been met, Parent shall be entitled to
- ----------
designate four of the six authorized directors on the Company's Board (the
"Parent Directors").  The Parent Directors shall be Anthony J. DeLuca, Philip O.
 ----------------                                                               
Strawbridge, James G. Kirk and James R. Mahoney.  Immediately following delivery
to the Depositary of the Notice of Acceptance, the resignations as directors of
the Company of Walter C. Barber, David L. Myers and Ronald G. Peterson,
delivered to Parent concurrently with the execution and delivery of this
Agreement, shall be deemed effective and Allan S. Bufferd and Ernie Green, as
the remaining directors of the Company (the "Continuing Directors") shall
                                             --------------------        
execute and deliver a written consent or shall otherwise take effective action
electing the Parent Directors to the Company's Board.  The Continuing Directors
shall remain members of such Board until the Effective Time (as defined in
Section 2.3), and, in lieu of Continuing Directors, if the same shall not serve,
the Company shall use reasonable efforts to ensure that the Company's Board
shall consist of at least two members who are neither officers, stockholders,
designees nor Affiliates of Parent or FD or their respective Affiliates (the
"Special Directors").  In the event a Continuing Director resigns from the
 -----------------                                                        
Company's Board, Parent, Merger Sub and the Company shall permit the remaining
Continuing Director or Directors to appoint the resigning director's successor
who shall be deemed to be a Continuing Director.  Immediately following the
election of the Parent Directors, the Company will use reasonable efforts to
cause persons designated by Parent to constitute the same percentage as the
Parent Directors represent on the Company's Board of (i) each committee of such
Board (other than any committee of such Board established to take action under
this Agreement), (ii) each board of directors of each Subsidiary of the Company
and (iii) each committee of each such board.

          (b) The Company's obligation to appoint designees to the Company's
Board shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder.  The Company shall promptly take all action required
pursuant to such Section and Rule in order to fulfill its obligations under this
Section 1.3 and shall include in the Schedule 14D-9 such information with
respect to the Company and its officers and directors as is required under such
Section and Rule in order to fulfill its obligations under this Section 1.3.
Parent will supply to the Company in writing and be solely responsible for any
information with respect to itself and its nominees, officers, directors and
Affiliates required by such Section and Rule.

          (c) Following the election or appointment of Parent's designees
pursuant to this Section 1.3 and prior to the Effective Time, if there shall be
any Continuing Directors and/or Special Directors, any amendment of this
Agreement, any termination of this Agreement by the Company, any extension by
the Company of the time for the performance of any of the obligations or other
acts of Parent or any waiver of any of the Company's rights hereunder, will
require the concurrence of a majority of such Continuing Directors and Special
Directors.

                      THE MERGER; CLOSING; EFFECTIVE TIME

     2.1.  The Merger.  Upon the terms and subject to the conditions set forth
           ----------                                                           
in this Agreement, at the Effective Time (as defined in Section 2.3) Merger Sub
shall be merged with and into the Company and the separate corporate existence
of Merger Sub shall thereupon cease.  The Company shall be the surviving
corporation in the Merger (sometimes hereinafter referred to as the "Surviving
                                                                     ---------

Delaware, and the separate corporate existence of the Company with all its
rights, privileges, immunities, powers and franchises shall continue unaffected
by the Merger, except as set forth in Article III.  At the election of Parent,
to the extent that such action would not cause a failure of a condition to the
Offer or the Merger, the Merger may be structured so that the Company shall be
merged with and into Merger Sub with the result that Merger Sub shall become the
"Surviving Corporation."  The Merger shall have the effects specified in the
DGCL.  Parent, as the sole stockholder of Merger Sub, hereby approves the Merger
and this Agreement.

     2.2.  Closing.  The closing of the Merger (the "Closing") shall take place 
           -------                                   -------

Angeles, California at 9:00 a.m., Pacific time, on the first Business Day after
the day on which the last to be fulfilled or waived of the conditions set forth
in Article VII (other than those conditions that by their nature are to be
satisfied at the Closing, but subject to the fulfillment or waiver of those
conditions) shall be satisfied or waived in accordance with this Agreement or
(ii) at such other place and time and/or on such other date as the Company and
Parent may agree in writing (the "Closing Date").
                                  ------------   

     2.3.  Effective Time.  As soon as practicable following the Closing, the

Company and Parent will cause a Certificate of Merger (the "Delaware Certificate

of Delaware as provided in Section 251 of the DGCL.  The Merger shall become
effective at the time when the Delaware Certificate of Merger has been duly
filed with the Secretary of State of Delaware (the "Effective Time").

                     CERTIFICATES FOR MERGER CONSIDERATION

     4.1.  Effect on Capital Stock.  At the Effective Time, as a result of the
           -----------------------                                              
Merger and without any action on the part of the holder of any Capital Stock (as
defined in Section 9.2) of the Company:

          (a)  Merger Consideration.  Each Share issued and outstanding
               --------------------

          (b)  Cancellation of Excluded Shares.  Each Excluded Share issued
               -------------------------------                               
and outstanding immediately prior to the Effective Time shall, by virtue of the
Merger and without any action on the part of the holder thereof, cease to be
outstanding, shall be canceled and retired without payment of any consideration
therefor and shall cease to exist.

          (c)  Merger Sub.  At the Effective Time, each share of Common Stock,
               ----------                                                       
par value $.01 per share, of Merger Sub issued and outstanding immediately prior
to the Effective Time shall be converted into one share of Common Stock of the
Surviving Corporation.

     4.2.  Exchange of Certificates for Payment.
           ------------------------------------   

          (a)  Exchange Agent.  As of the Effective Time, Parent shall deposit, 
               --------------

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

aggregate outstanding Shares (other than Excluded Shares) to be paid pursuant to
Section 4.1(a) in exchange for outstanding Shares upon due surrender of the
Certificates (or affidavits of loss in lieu thereof) pursuant to the provisions
of this Article IV (such aggregate cash amount when paid to the Exchange Agent
being hereinafter referred to as the "Merger Fund").
                                      -----------   

          (b)  Exchange Procedures.  Promptly after the Effective Time, the
               -------------------                                           
Surviving Corporation shall cause the Exchange Agent to mail to each holder of
record of Shares (other 

                                       8
<PAGE>
 
than holders of Excluded Shares) (i) a letter of transmittal (which shall, among
other matters, specify that delivery of the Certificates shall be effected, and
risk of loss and title to the Certificates shall pass, only upon actual receipt
of the Certificates (or affidavits of loss in lieu thereof) by the Exchange
Agent) and (ii) instructions for use in effecting the surrender of the
Certificates in exchange for the Merger Consideration due and payable to such
holder. Upon surrender of a Certificate for cancellation to the Exchange Agent
together with such letter of transmittal, duly executed, the holder of such
Certificate shall be entitled to receive in exchange therefor a check in the
amount (after giving effect to any required tax withholdings) of the Merger
Consideration due and payable in respect of such holder's Shares and the
Certificate so surrendered shall forthwith be canceled. No interest will be paid
or accrued on any amount payable upon due surrender of the Certificates. All
Merger Consideration paid upon surrender for exchange of Shares in accordance
with the terms of this Agreement shall be deemed to have been paid in full
satisfaction of all rights pertaining to such Shares. In the event of a transfer
of ownership of Shares that is not registered in the transfer records of the
Company, a check for the amount of cash to be paid upon due surrender of the
Certificate may be delivered to such a transferee if the Certificate formerly
representing such Shares is presented to the Exchange Agent, accompanied by all
documents required by the Exchange Agent to evidence and effect such transfer
and to evidence that any applicable stock transfer taxes have been paid.

          (c)  Transfers.  After the Effective Time, there shall be no 
               ---------                                                
transfers on the stock transfer books of the Company of the Shares that were
outstanding immediately prior to the Effective Time.

          (d)  Termination of Merger Fund.  Any portion of the Merger Fund
               --------------------------                                   
(including the proceeds of any investments thereof) that remains unclaimed by
the stockholders of the Company for 180 days after the Effective Time shall be
paid to Parent.  Any stockholders of the Company who have not theretofore
complied with this Article IV shall thereafter look only to Parent for payment
of their Merger Consideration payable pursuant to Section 4.1 upon due surrender
of their Certificates (or affidavits of loss in lieu thereof), in each case,
without any interest thereon.  Notwithstanding the foregoing, neither Parent,
the Surviving Corporation, the Exchange Agent nor any other Person shall be
liable to any former holder of Shares for any amount properly delivered to a
public official pursuant to applicable abandoned property, escheat or similar
laws.

          (e)  Return of Consideration.  Any portion of the Merger Fund
               -----------------------                                   
representing Merger Consideration payable in respect of Dissenters' Shares (as
defined in Section 4.3) for which appraisal rights have been perfected shall be
returned to Parent, upon demand.

          (f)  Lost, Stolen or Destroyed Certificates.  In the event any
               --------------------------------------                     
Certificate shall have 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 and, if required by Parent, the posting by such Person of a
bond in an amount determined by Parent as indemnity against any claim that may
be made against it with respect to such Certificate, the Exchange Agent will
issue in exchange for such lost, stolen or destroyed Certificate the Merger
Consideration payable pursuant to Section 4.1 upon due surrender of the
Certificate representing such Shares pursuant to this Agreement.

     4.3.  Dissenters' Shares.  Notwithstanding Section 4.1, Shares outstanding 
           ------------------                                        
immediately prior to the Effective Time and held by a holder who has not voted
in favor of the Merger or consented thereto in writing and who has demanded
appraisal for such Shares in accordance with the DGCL ("Dissenters' Shares")
                                                        ------------------
shall not be converted into a right to receive the Merger Consideration, unless
such holder fails to perfect or withdraws or otherwise loses such holder's right
to appraisal. If after the Effective Time such holder fails to perfect or
withdraws or loses such holder's right to appraisal, such Dissenters' Shares
shall be treated as if they had been converted as of the Effective Time into a
right to receive the Merger Consideration. The Company shall give Parent prompt
notice of any demands received by the Company for appraisal of Dissenters'
Shares, and Parent shall have the right to participate in all negotiations and
proceedings with respect to such demands. The Company shall not, except with the
prior written consent of Parent, make any payment with respect to, or settle or
offer to settle, any such demands.

                             ------------
annexes and any amendments thereto) filed with the SEC (collectively, including
any such reports filed subsequent to the date hereof, the "Company Reports"). As
                                                           ---------------
of their respective dates, the Company Reports complied, and any Company Reports
filed with the SEC after the date hereof will comply, as to form in all material
respects with the applicable requirements of the Exchange Act and the Securities
Act of 1933, as amended (the "Securities Act"), and the Company Reports did not,
                              --------------
and any Company Reports filed with the SEC after the date hereof will not, at
the time of their filing, contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements made therein, in light of the circumstances in which they were
made, not misleading. Each of the consolidated balance sheets included in or
incorporated by reference into the Company Reports (including the related notes
and schedules) fairly presents, or will fairly present, the consolidated
financial position of the Company and its Subsidiaries as of its date and each
of the consolidated statements of income and of changes in financial position
included in or incorporated by reference into the Company Reports (including any
related notes and schedules) fairly presents, or will fairly present, the
results of operations, retained earnings and changes in financial position, as
the case may be, of the Company and its Subsidiaries for the periods set forth
therein (subject, in the case of unaudited statements, to notes and normal year-
end audit adjustments that will not be material in amount or effect), in each
case in accordance with United States generally accepted accounting principles
("GAAP") consistently applied during the periods involved, except as may be

noted therein. The Company has heretofore made available or promptly will make
available to Parent a complete and correct copy of all amendments or
modifications (in draft or final form) which are required to be filed with the
SEC but have not yet been filed with the SEC to the Company Reports, agreements,
documents or other instruments which previously had been filed by the Company
with the SEC pursuant to the Exchange Act. For purposes of this Agreement,
"Balance Sheet" means the consolidated balance sheet of the Company as of
 -------------
October 31, 1997 set forth in the Company 10-K. Except as set forth in Company
Reports filed with the SEC prior to the date hereof or as incurred in the
ordinary course of business since the date of the most recent financial
statements included in the Company Reports, neither the Company nor any of its
subsidiaries has any liabilities or obligations of any nature (whether accrued,
absolute, contingent or otherwise) which would be required under GAAP to be set
forth on a consolidated balance sheet of the Company and its subsidiaries taken
as a whole and which individually or in the aggregate would have a Company
Material Adverse Effect.

filed prior to the date hereof, the businesses of each of the Company and its
Subsidiaries have not been, and are not being, conducted in violation of any
law, ordinance, regulation, judgment, order, injunction, decree, arbitration
award, license or permit of any Governmental Entity (collectively, "Laws"),
                                                                    ----   
except for violations or possible violations that, individually or in the
aggregate, have not had and are not reasonably likely to have a Company Material

is sufficient to render inapplicable to the Offer, the Merger, this Agreement,
and the transactions contemplated by this Agreement the provisions of Section
203 of DGCL to the extent, if any, such Section is applicable to the Offer, the
Merger, this Agreement and the transactions contemplated by this Agreement.

          (k) Environmental Matters.
              ---------------------   

              (i) The term "Environmental Laws" means any Federal, state, local
or foreign statute, treaty, ordinance, rule, regulation, policy, permit,
consent, approval, license, judgment, order, decree or injunction relating to:
(A) Releases (as defined in 42 U.S.C. (S) 9601(22)) or threatened Releases of
Hazardous Material (as hereinafter defined) into the environment, (B) the
generation, treatment, storage, presence, disposal, use, handling,
manufacturing, transportation or shipment of Hazardous Material, (C) natural
resources, or (D) the environment, and includes all "Environmental Laws" as they

including crude oil and any fractions thereof, (3) natural gas, synthetic gas
and any mixtures thereof, (4) asbestos and/or asbestos containing materials, (5)
PCBs or materials containing PCBs, (6) radioactive materials, and (7) "Hazardous
Substance" or "Hazardous Material" as those terms are defined in any
indemnification provision in any contract, lease, or agreement to which the
Company is a party.

              (ii)  During the period of ownership or operation by the Company
and its Subsidiaries of any of their current or previously owned or leased
properties, and to the knowledge of the executive officers of the Company there
have been no Releases of Hazardous Material by the Company or any of its
Subsidiaries in, on, under or affecting such properties or 

                                       17
<PAGE>
 
any surrounding site, and neither the Company nor any of its Subsidiaries has
disposed of any Hazardous Material in a manner that has led, or could reasonably
be anticipated to lead to a Release, except in each case for those which
individually or in the aggregate would not have a Company Material Adverse
Effect, and except as disclosed in the Company Reports. Except as set forth on
Schedule 5.1(k), to the knowledge of the executive officers of the Company there
have been no Releases of Hazardous Material by the Company or any of its
Subsidiaries in, on, under or affecting such properties or any surrounding site

other party except in each case for those which individually on in the aggregate
would not have a Company Material Adverse Effect. To the knowledge of the
executive officers of the Company no third party property is contaminated with
any Hazardous Substances that may subject the Company or any of its Subsidiaries
to liability under any Environmental Laws. The Company and its Subsidiaries have
not received any written notice of, or entered into any order, settlement or
decree relating to: (A) any violation of any Environmental Laws or the
institution or pendency of any suit, action, claim, proceeding or investigation
by any Governmental Entity or any third party in connection with any alleged
violation of Environmental Laws, (B) the response to or remediation of Hazardous
Material at or arising from any of the Company's properties or any Subsidiary's

              (iii) To the knowledge of the executive officers of the Company
there are no circumstances or conditions involving the Company, any of its
Subsidiaries or their respective employees that could reasonably be expected to
result in any material claims, liability or investigations under any
Environmental Law or relating to Hazardous Substances arising out of the
ownership, operation, management of all or any portion of a facility, or out of
the arrangement for the treatment, transportation, or disposal of, or ownership
or possession or choice of the treatment, storage or disposal facility for, any
material with respect and to the extent to which the Company or its Subsidiaries
provided services before the Closing.

(collectively, the "Intellectual Property Rights"). There are no Liens other

consolidated financial statements for any Taxes that have not been paid, whether

the Company nor any of its Subsidiaries is a party to or otherwise bound by any
collective bargaining agreement, contract or other agreement or understanding
with a labor union or labor organization, nor is the Company or any of its

the Parent or Merger Sub to consummate the transactions contemplated by this
Agreement.

               (ii) The execution, delivery and performance of this Agreement by

the Merger and the other transactions contemplated hereby will not, constitute
or result in (A) a breach or violation of, or a default under, the certificate
or bylaws of Parent or Merger Sub, (B) a breach or violation of, or a default
under, the acceleration of or the creation of a Lien, on the assets of Parent or
any of its Subsidiaries (with or without notice, lapse of time or both) pursuant
to, any Contract binding upon Parent or any of its Subsidiaries or any Law to
which Parent or any of its Subsidiaries is subject or (C) any change in the
rights or obligations of any party under any such Contract, except, in the case

     6.2.  Third Party Acquisitions.
           ------------------------

           (a) The Company agrees that neither it nor any of its Subsidiaries
nor any of its or its Subsidiaries' employees or directors shall, and it shall
direct and use its best efforts to 

                                       25
<PAGE>
 
cause its and its Subsidiaries' agents and representatives (including the
Financial Advisor or any other investment banker and any attorney or accountant
retained by it or any of its Subsidiaries (collectively, "Company Advisors"))
                                                          ----------------
not to, directly or indirectly, initiate, solicit or otherwise facilitate any
inquiries in respect of, or the making of any proposal for, a Third Party
Acquisition (as defined in Section 6.2(b)). The Company further agrees that
neither it nor any of its Subsidiaries nor any of its or its Subsidiaries'
employees or directors shall, and it shall direct and use its best efforts to
cause all Company Advisors not to engage in any negotiations concerning, or
provide any confidential information or data to, or have any discussions with,
any Third Party (as defined in Section 6.2(b)) relating to the proposal of a
Third Party Acquisition, or otherwise attempt to make or implement a Third Party
Acquisition; provided, however, that if at any time prior to the acceptance for
payment of Shares pursuant to the Offer, the Company's Board determines in good
faith, after taking into consideration the advice of its outside legal counsel,
that it is likely to be required in order for its members to comply with their
fiduciary duties under applicable law, the Company may, in response to an
inquiry, proposal or offer for a Third Party Acquisition which was not solicited
subsequent to the date hereof, (x) furnish non-public information with respect
to the Company to any such person pursuant to a confidentiality agreement on
terms substantially similar to the confidentiality agreement entered into
between the Company and Parent prior to the execution of this Agreement and (y)
participate in discussions and negotiations regarding such inquiry, proposal or
offer; and provided, further, that nothing contained in this Agreement shall
prevent the Company or the Company's Board from complying with Rules 14d-9 and
14e-2 promulgated under the Exchange Act with regard to any proposed Third Party
Acquisition or withdrawing its recommendation of the Offer or the Merger
pursuant to Section 6.2(b). The Company shall immediately cease and cause to be
terminated any existing activities, discussions or negotiations with any Third
Parties conducted heretofore with respect to any of the foregoing. The Company
shall take the necessary steps to promptly inform all Company Advisors of the
obligations undertaken in this Section 6.2(a). The Company agrees to notify
Parent as promptly as reasonably practicable in writing if (i) any inquiries
relating to or proposals for a Third Party Acquisition are received by the
Company, any of its Subsidiaries or any of the Company Advisors, (ii) any
confidential or other non-public information about the Company or any of its
Subsidiaries is requested from the Company, any of its Subsidiaries or any of
the Company Advisors, or (iii) any negotiations or discussions in connection
with a possible Third Party Acquisition are sought to be initiated or continued
with the Company, any of its Subsidiaries or any of the Company Advisors
indicating, in connection with such notice, the principal terms and conditions
of any proposals or offers, and thereafter shall keep Parent informed in
writing, on a reasonably current basis, on the status and terms of any such
proposals or offers and the status of any such negotiations or discussions. The
Company also agrees promptly to request each Person that has heretofore executed
a confidentiality agreement in connection with its consideration of acquiring
the Company or any of its Subsidiaries, if any, to return all confidential
information heretofore furnished to such Person by or on half of the Company or
any of its Subsidiaries.

           (b) Except as permitted by this Section 6.2(b), the Company's Board
shall not withdraw its recommendation of the Offer or the Merger and the other
transactions contemplated hereby or approve or recommend, or cause the Company
to enter into any agreement with respect to, any Third Party Acquisition.
Notwithstanding the preceding sentence, if the Company's 

                                       26
<PAGE>
 
Board determines in its good faith judgment, after taking into consideration the
advice of its outside legal counsel, that it is likely to be required in order
for its members to comply with their fiduciary duties under applicable law, the
Company's Board may withdraw its recommendation of the Offer or the Merger and
the other transactions contemplated hereby, or approve or recommend or cause the
Company to enter into an agreement with respect to a Superior Proposal (as
defined below); provided, however, that the Company shall not be entitled to
enter into any agreement with respect to a Superior Proposal unless this
Agreement is concurrently terminated by its terms pursuant to Section 8.3(c).
For purposes of this Agreement, "Third Party Acquisition" means the occurrence
                                 -----------------------
of any of the following events: (i) the acquisition of the Company by merger or
otherwise by any Person (which includes a "person" as such term is defined in
Section 13(d)(3) of the Exchange Act) other than Parent, Merger Sub or any
Affiliate thereof (a "Third Party"); (ii) the acquisition by a Third Party of
                      -----------
20% or more of the total assets of the Company and its Subsidiaries, taken as a
whole (other than the purchase of the Company's products in the ordinary course
of business); (iii) the acquisition by a Third Party of 20% or more of the
outstanding Shares; (iv) the adoption by the Company of a plan of partial or
complete liquidation or the declaration or payment of an extraordinary dividend;
(v) the repurchase by the Company or any of its Subsidiaries of 20% or more of
the outstanding Shares; or (vi) the acquisition by the Company or any of its
Subsidiaries by merger, purchase of stock or assets, joint venture or otherwise
of a direct or indirect ownership interest or investment in any business whose
annual revenues, net income or assets is equal to or greater than 20% of the
annual revenues, net income or assets of the Company and its Subsidiaries, taken
as a whole. For purposes of this Agreement, a "Superior Proposal" means any bona
                                               -----------------
fide proposal to acquire directly or indirectly for consideration consisting of
cash and/or securities more than 50% of the Shares then outstanding or all or
substantially all the assets of the Company and its Subsidiaries, taken as a
whole, and otherwise on terms which the Board of Directors of the Company by a
majority vote determines in its good faith judgment (after consultation with the
Financial Advisor or another financial adviser of nationally recognized
reputation) to be reasonably capable of being completed (taking into account all
material legal, financial, regulatory and other aspects of the proposal and the
Third Party making the proposal, including the availability of financing
therefor) and more favorable to the Company's stockholders from a financial
point of view than the transactions contemplated by this Agreement.

     6.3.   Filings; Other Actions; Notification.
            ------------------------------------

            (a) If a vote of the Company's stockholders is required by law in
order to consummate the Merger, the Company shall promptly, following
consummation of the Offer, prepare and file with the SEC the Proxy Statement,
which shall include the recommendation of the Company's Board that stockholders
of the Company vote in favor of the approval and adoption of this Agreement and
the written opinion of the Financial Advisor that the cash consideration to be
received by the stockholders of the Company pursuant to the Merger is fair to
such stockholders from a financial point of view.  The Company shall use all
reasonable efforts to have the Proxy Statement cleared by the SEC as promptly as
practicable after such filing, and promptly thereafter mail the Proxy Statement
to the stockholders of the Company.  The Company shall also use its best efforts
to obtain all necessary state securities law or "blue sky" permits and approvals
required in connection with the Merger and to consummate the other transactions
contemplated by this Agreement and will pay all expenses incident thereto.

           (b) Upon and subject to the terms and conditions set forth in this
Agreement, the Company and Parent shall cooperate with each other and use (and
shall cause their respective Subsidiaries to use) all reasonable efforts to take
or cause to be taken all actions, and do or cause to be done all things,
necessary, proper or advisable under this Agreement and applicable Laws to
consummate and make effective the Offer, the Merger and the other transactions
contemplated by this Agreement as soon as practicable, including preparing and
filing as promptly as practicable all documentation to effect all necessary
applications, notices, petitions, filings and other documents and to obtain as
promptly as practicable all permits, consents, approvals and authorizations
necessary or advisable to be obtained from any third party and/or any
Governmental Entity in order to consummate the Offer, the Merger or any of the
other transactions contemplated by this Agreement; provided, however, that
nothing in this Section 6.3 shall require, or be construed to require, Parent to
proffer to, or agree to, sell or hold separate and agree to sell, before or
after the Effective Time, any material assets, businesses or any interest in any
material assets or businesses of Parent, the Company or any of their respective
Affiliates (or to consent to any sale, or agreement to sell, by the Company of
any of its material assets or businesses) or to agree to any material change in
or material restriction on the operations of any such assets or businesses;
provided, further, that nothing in this Section 6.3 shall require, or be
construed to require, a proffer or agreement that would, in the reasonable
judgment of Parent, be likely to have a material adverse effect on the
anticipated financial condition, properties, business or results of operations
of the Parent and its Subsidiaries after the Merger, taken as a whole, in order
to obtain any necessary or advisable consent, registration, approval, permit or
authorization from any Governmental Agency.  Subject to applicable Laws relating
to the exchange of information, Parent and the Company shall have the right to
review in advance, and to the extent practicable each will consult the other on,
all the information relating to Parent or the Company, as the case may be, and
any of their respective Subsidiaries, that appears in any filing made with, or
written materials submitted to, any third party and/or any Governmental Entity
in connection with the Offer, the Merger and the other transactions contemplated
by this Agreement, including the Proxy Statement.  In exercising the foregoing
right, the Company and Parent shall act reasonably and as promptly as
practicable.

           (c) Each of the Company and Parent shall, upon request by the other,
furnish the other with all information concerning itself, its Subsidiaries,
directors, officers and stockholders and such other matters as may be reasonably
necessary or advisable in connection with filings pursuant to the HSR Act, the
Proxy Statement or any other statement, filing, notice or application made by or
on behalf of Parent, the Company or any of their respective Subsidiaries to any
Governmental Entity or other Person (including the NASD) in connection with the
Offer, the Merger and the other transactions contemplated by this Agreement.

           (d) Each of the Company and Parent shall keep the other apprised of
the status of matters relating to completion of the transactions contemplated
hereby, including promptly furnishing the other with copies of notices or other
communications received by Parent or the Company, as the case may be, or any of
their respective Subsidiaries, from any third party and/or any Governmental
Entity alleging that the consent of such third party or Governmental Entity is
or may be required with respect to the Offer, the Merger and the other
transactions contemplated by this Agreement.  Each of the Company and Parent
shall give prompt notice to the other of (i) the occurrence or non-occurrence of
any fact or event which would be reasonably likely (x) to 

                                       28
<PAGE>
 
cause any representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect at any time from the date hereof to the
Effective Time or (y) to cause any covenant, condition or agreement under this
Agreement not to be complied with or satisfied and (ii) any failure of the
Company, Parent or Merger Sub, as the case may be, to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder.

     6.4.  Information Supplied.  Each of Parent and the Company agrees, as to
           --------------------
information provided by itself and its Subsidiaries, that none of the
information included or incorporated by reference in the proxy statement, if
any, delivered by the Company to its stockholders in connection with the Merger
and any amendment or supplement thereto (the "Proxy Statement") will, at the
                                              --------------- 
time the Proxy Statement is cleared by the SEC, at the date of mailing to
stockholders of the Company, and at the time of the Stockholders Meeting (as
defined in Section 6.5),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 were
made, not misleading.

     6.5.  Stockholders Meeting.
           --------------------

           (a) If a vote of the Company's stockholders is required by law in
order to consummate the Merger, the Company will, following consummation of the
Offer, take, in accordance with applicable Law and its certificate of
incorporation and bylaws, all action necessary to convene a meeting of holders
of Shares (the "Stockholders Meeting") as promptly as practicable after the
                --------------------                                       
Proxy Statement is cleared by the SEC to consider and vote upon the approval of
this Agreement.  The Proxy Statement shall include a statement that the
Company's Board approved this Agreement and recommended that the Company's
stockholders vote in favor of this Merger, and the Company shall use all
reasonable and customary efforts to solicit such approval; provided, however,
that if the Company's Board determines in good faith, after taking into
consideration the advice of its outside legal counsel, that the Proxy Statement
not containing such recommendation is likely to be required in order for its
members to comply with their fiduciary duties under applicable law, then any
failure of the Proxy Statement to contain such recommendation shall not
constitute a breach of this Agreement.  Notwithstanding the foregoing, if
Parent, Merger Sub and/or any other Subsidiary of Parent shall acquire at least
90% of the outstanding Shares, the parties shall take all necessary and
appropriate action to cause the Merger to become effective as soon as
practicable after consummation of the Offer without a Stockholders Meeting in
accordance with Section 253 of the DGCL.

           (b) Following the purchase of Shares, if any, pursuant to the Offer,
Parent shall ensure that all such Shares purchased continue to be held by
Parent, Merger Sub, and/or a direct or indirect wholly-owned subsidiary of
Parent until such time as the Merger is consummated.  At the Stockholders
Meeting, Parent agrees to cause all Shares purchased pursuant to the Offer and
all other Shares owned by Parent, Merger Sub or any Subsidiary of Parent to be
voted in favor of the Merger.

     6.6.  Access.  Upon reasonable notice, and except as may otherwise be
           ------
required by applicable law or relevant contractual provisions contained in such
agreements, the Company shall (and shall cause its Subsidiaries to) (i) afford
Parent's officers, employees, counsel, 

                                       29
<PAGE>
 
accountants and other authorized representatives (collectively,
"Representatives") access, during normal business hours throughout the period
 ---------------
prior to the Effective Time, to its properties, books, contracts and records
and, during such period, (ii) furnish promptly to Parent all information
concerning its business, properties and personnel as may reasonably be
requested; provided, however, that no investigation pursuant to this Section 6.6
shall affect or be deemed to modify any representation or warranty made by the
Company. All requests for information made pursuant to this Section 6.6 shall be
directed to an executive officer of the Company or such Person as may be
designated by its officers. All of the information provided to or obtained by
Parent, its Affiliates and Representatives shall be treated as "Confidential
Information" under, and the parties shall comply with, and shall cause their
respective Representatives to comply with, all their respective obligations
under, the Confidentiality Agreement, dated July 28, 1998, between the Company
and Parent (the "Confidentiality Agreement").
                 -------------------------  

     6.7.  Publicity.  The initial press release concerning the Merger has been
           ---------
approved by Parent and the Company and thereafter the Company and its
Subsidiaries, on the one hand, and Parent and Merger Sub, on the other hand,
shall consult with each other prior to issuing any press releases or otherwise
making public announcements with respect to the Merger and the other
transactions contemplated by this Agreement and prior to making any filings with
any Governmental Entity or other Person (including the New York Stock Exchange
or the NASD) with respect hereto, except as may be required by law or by
obligations pursuant to any listing agreement.

     6.8.  Status of Company Employees; Company Stock Options; Employee Benefits
           ---------------------------------------------------------------------

           (a) Parent agrees that following the Effective Time, the employees of
the Company and its Subsidiaries who are employed by the Surviving Corporation
or its Subsidiaries ("Company Employees") shall become eligible to participate
                      -----------------                                       
in the employee benefit plans and arrangements maintained by Parent or its
Subsidiaries ("Parent Benefit Plans") including, without limitation, severance
               --------------------                                           
plans, in the same manner as similarly situated employees of Parent.  Parent or
its Subsidiaries shall grant the Company Employees credit for all service
credited by the Company for purposes of eligibility, vesting and the
determination of benefits under vacation and severance pay plans.  Parent shall,
and shall cause the Surviving Corporation to, honor in accordance with their
terms all employee benefit obligations to current and former employees under the
Compensation and Benefit Plans in existence on the date hereof (including,
without limitation, the plans and agreements listed on Schedule 5.1(h)(i)) and
                                                       ------------------     
all employment or severance agreements entered into by the Company or adopted by
the Company's Board prior to the Effective Date (collectively, the "Employment
                                                                    ----------
and Severance Agreements"); it being understood that nothing contained herein
- ------------------------    -------------------                              
shall limit or restrict the ability of Parent to modify or terminate any
Compensation and Benefit Plan, or to merge any Compensation and Benefit Plan
with any other plan, other than the Employment and Severance Agreements,
following the Effective Time.

           (b) From and after the date hereof, the Company agrees that, except
with respect to grants in connection with offers of employment outstanding on
October 23, 1998, it will not grant additional stock options under the Stock
Option Plans.

                                       30
<PAGE>
 
          (c) Any pre-existing condition exclusion under any Parent Benefit Plan
providing medical or dental benefits shall be waived for any Company Employee
who, immediately prior to commencing participation in such Parent Benefit Plan,
was participating in a Company Benefit Plan providing medical or dental benefits
and had satisfied any pre-existing condition provision under such Company
Benefit Plan.  Any expenses that were taken into account under a Company Benefit
Plan providing medical or dental benefits in which the Company Employee
participated immediately prior to commencing participation in a Parent Benefit
Plan providing medical or dental benefits shall be taken into account to the
same extent under such Parent Benefit Plan, in accordance with the terms of such
Parent Benefit Plan, for purposes of satisfying applicable deductible,
coinsurance and maximum out-of-pocket provisions and life-time benefit limits.

     6.9. Expenses.  The Surviving Corporation shall pay all charges and
          --------                                                      
expenses, including those of the Exchange Agent, in connection with the
transactions contemplated in Article IV.  Except as otherwise provided in
Sections 8.5, whether or not the Merger is consummated, all costs and expenses
incurred in connection with this Agreement and the Merger and the other
transactions contemplated by this Agreement shall be paid by the party incurring
such expense.

     6.10.  Indemnification; Directors' and Officers' Insurance.
            --------------------------------------------------- 

            (a) From and after the Effective Time, Parent and the Surviving
Corporation shall jointly and severally indemnify, defend and hold harmless each
person who is now, or has been at any time prior to the date of this Agreement
or who becomes prior to the Effective Time a director, officer, employee or
agent of the Company or any of its Subsidiaries (when acting in such capacity)
(each individually an "Indemnified Party", and collectively, the "Indemnified
                       -----------------                          -----------
Parties"), against any costs or expenses (including reasonable attorneys' fees
- -------                                                                       
and expenses), judgments, settlement amounts, fines, losses, claims, demands,
damages or liabilities (collectively, "Costs") incurred in connection with any
                                       -----                                  
claim, action, suit, proceeding or investigation, whether civil, criminal or
administrative (each, a "Claim") arising out of matters existing or occurring
                         -----                                                
prior to or after the Effective Time, whether threatened, asserted or claimed
prior to, at or after the Effective Time, which is based in whole or in part on,
or arising in whole or in part out of the fact that such person is or was a
director (including as a member of the Special Committee) or officer of the
Company or any of its Subsidiaries including, without limitation, all Costs
based in whole or in part on, or arising in whole or in part out of, or
pertaining to this Agreement or the transactions contemplated hereby, including
the Offer and the Merger, to the fullest extent that the Company would have been
permitted under the DGCL and its certificate of incorporation, bylaws and other
agreements in effect on the date hereof to indemnify such individual.  Parent
shall, or shall cause the Company (or the Surviving Corporation after the
Effective Time) to, pay all Costs in advance of the final disposition of any
Claim to each Indemnified Party to the fullest extent provided in the Company's
certificate of incorporation or bylaws as in effect on the date hereof, subject
to receipt by Parent or the Company (or the Surviving Corporation after the
Effective Time) of an undertaking by or on behalf of such Indemnified Party
contemplated by Section 145(e) of the DGCL.  Without limiting the generality or
effect of the foregoing, in the event any Claim is brought against any
Indemnified Party (whether arising before or after the Effective Time) and, in
the opinion of 

                                       31
<PAGE>
 
counsel to an Indemnified Party, under applicable standards of professional
conduct, there is a conflict on any significant issue between the position of
the Company and an Indemnified Party, the Indemnified Parties may retain counsel
of their choice, which counsel shall be reasonably satisfactory to Parent and
the Company (or the Surviving Corporation after the Effective Time) (it being
understood that Testa, Hurwitz & Thibeault, LLP is acceptable to Parent and the
Company (and the Surviving Corporation after the Effective Time)), and Parent
shall, or shall cause the Company (or the Surviving Corporation after the
Effective Time) to, pay all reasonable fees and expenses of such counsel for the
Indemnified Parties promptly as statements therefor are received. The
Indemnified Parties as a group may not retain more than one law firm (in
addition to local counsel) to represent them with respect to each such matter
unless there is, in the opinion of counsel to an Indemnified Party, under
applicable standards of professional conduct, a conflict on any significant
issue between the positions of any two or more Indemnified Parties. The Company,
Parent and the Merger Sub (or the Surviving Corporation after the Effective
Time) agree that all rights to indemnification, including provisions relating to
advances of Costs incurred with respect to matters occurring through the
Effective Time, shall survive six years from the Effective Time; provided,
however, that all rights to indemnification in respect of any Claim asserted or
made within such period shall continue until the disposition of such Claim.

          (b) Any Indemnified Party wishing to claim indemnification under
subsection (a) of this Section 6.l0, upon learning of any such Claim, shall
promptly notify Parent and the Surviving Corporation thereof (but the failure so
to notify Parent and the Surviving Corporation shall not relieve them from any
liability which they may have under this Section 6.10 except to the extent such
failure materially prejudices such party).  In the event of any such Claim
(whether arising before or after the Effective Time), Parent and the Surviving
Corporation shall have the right to assume the defense of any Claim for which an
Indemnified Party is entitled to indemnification under subsection (a) of this
Section 6.10 with counsel reasonably acceptable to such Indemnified Party (which
right shall not affect the right of the Indemnified Parties to be reimbursed for
fees and expenses of separate counsel under the circumstances specified in
Section 6.10(a)).  Except as otherwise provided in this Section 6.10, neither
the Parent nor the Surviving Corporation shall be liable to any such Indemnified
Party for any legal expenses of other counsel or any other expenses incurred by
such Indemnified Party in connection with the defense thereof after either the
Parent or the Surviving Corporation, as the case may be, have assumed the
defense of such Claim.  The Indemnified Party will cooperate in all respects as
reasonably requested by Parent or the Surviving Corporation, as the case may be,
in the defense of any such matter and in connection therewith, shall be entitled
to reimbursement by Parent of reasonable expenses incurred in connection
therewith on a current basis.  Neither Parent nor the Surviving Corporation, as
the case may be, shall have any obligation hereunder to any Indemnified Party if
and when a court shall ultimately determine, and such determination shall have
become final and nonappealable, that the indemnification of such Indemnified
Party in the manner contemplated by this Section 6.10 is prohibited by law.  If
such indemnity is not available with respect to any Indemnified Party, then
Parent, the Company and the Merger Sub (or the Surviving Corporation after the
Effective Date), on the one hand, and the Indemnified Party, on the other hand,
shall contribute to the amount payable in such proportion as is appropriate to
reflect relative faults and benefits.

                                       32
<PAGE>
 
          (c) The Company shall purchase, and Parent shall reimburse the Company
at the Closing for the fully prepaid premium expense incurred for "Prior Acts"
Directors' & Officers' Liability Insurance to be effective with the signing of
this Agreement.  It is agreed the policy term will be for six years from the
date of this Agreement without restriction as to when any alleged or actual
wrongful acts or omissions may have occurred up to and including the date of
sale of the FD Shares to Merger Sub pursuant to the Offer.  The policy limits
combining both coverage agreements A & B (individual directors & officers
liability insurance and corporate reimbursement coverage) will be no less than
$25 million limits for the policy term with no more than a $250,000 deductible
for coverage B (corporate reimbursement coverage).  The corporate reimbursement
coverage part is to be extended to provide indemnity to the Company, FD and
Parent for their obligations, if any, to indemnify the individual directors and
officers of the Company, including its predecessor or successor names, if any,
for the Company directors' and officers' actual or alleged acts, errors or
omissions committed prior to or on the date of sale of the FD Shares to Merger
Sub.  Other terms and conditions are to be no less advantageous to the intended
beneficiaries thereof than FD's existing directors' and officers' liability
coverage.  This insurance policy is also to be primary to any other insurance or
indemnity obligation owed to the individuals from any of the parties to this
Agreement.  The Company shall not, without prior written consent of Parent,
purchase such coverage if the total cost of the coverage exceeds $200,000.  This
insurance is to be noncancellable except for the nonpayment of premium or the
ultimate failure of the FD Shares being purchased by Merger Sub.

          (d) The provisions of this Section 6.10 are intended to be for the
benefit of, and shall be enforceable by, each of the Indemnified Parties and
their respective heirs and estates.  Nothing in this Section 6.10 shall limit in
any way any other rights to indemnification that any current or former director
or officer of the Company or any of its Subsidiaries may have by contract or
otherwise.

          (e) Without limiting the effect of subsections (a) or (c) of this
Section 6.10, from and after the Effective Time, the Surviving Corporation shall
fulfill, assume and honor in all respects the obligations of the Company or any
of its Subsidiaries pursuant to the Company's or any of its Subsidiaries
certificate of incorporation, bylaws and any indemnification agreement between
the Company or any of its Subsidiaries which is set forth on Schedule 6.10 and
                                                             -------------    
any of their respective directors and officers existing and in force as of the
Effective Time.  The Surviving Corporation agrees that the indemnification
obligations set forth in the Company's certificate of incorporation and bylaws,
in each case as of the date of this Agreement, shall survive the Merger (and, as
of or prior to the Effective Time, Parent shall cause the bylaws of Merger Sub
to reflect such provisions).  No subsequent amendment of the provisions of the
bylaws of the Surviving Corporation shall affect the indemnification obligations
of Parent or the Surviving Corporation in any manner that would adversely affect
the rights of the Indemnified Parties under this Section 6.10.

          (f) If Parent or the Surviving Corporation or any of its successors or
assigns (i) shall consolidate with or merge into any other Person and shall not
be the continuing or surviving corporation or Person of such consolidation or
merger or (ii) shall transfer all or substantially all of its properties and
assets to any Person, then and in each such case, proper 

                                       33
<PAGE>
 
provisions shall be made so that the successors and assigns of the Parent and
Surviving Corporation shall assume all of the obligations set forth in this
Section 6.10.

     6.11.  Other Actions by the Company and Parent.  If any Takeover Statute is
            ---------------------------------------                             
or may become applicable to the Merger or the other transactions contemplated by
this Agreement, each of Parent and the Company and their respective Boards of
Directors shall grant such approvals and take such lawful actions as are
necessary so that such transactions may be consummated as promptly as
practicable on the terms contemplated by this Agreement or by the Merger and
otherwise act to eliminate or minimize the effects of such statute, and any
regulations promulgated thereunder, on such transactions.

     6.12.  Tender of Shares by FD; Cancellation of FD Stock Option.  FD agrees
            -------------------------------------------------------            
that it will tender all Shares owned by it or any of its Affiliates (including
the FD Shares) in, and will not withdraw such Shares from, the Offer.  FD
further agrees that FD Stock Option Agreement described in Schedule 5.1(h) shall
be deemed cancelled as of the date on which Parent delivers the Notice of
Acceptance to the Depositary.

     6.13.  Parent Stock Option; Exercise; Adjustments.
            ------------------------------------------ 

          (a) Subject to the terms and conditions set forth herein, the Company
hereby grants to Parent an irrevocable option (the "Parent Option") to purchase
                                                    -------------              
that number of authorized and unissued shares of Common Stock equal to 14% of
the outstanding Shares immediately after the exercise of the Parent Option (the
"Option Shares") at a purchase price per Option Share equal to the Offer Price
 -------------                                                                
(the "Option Price").  Subject to the conditions set forth in subsection (c)
      ------------                                                          
below, the Parent Option may be exercised by Parent, in whole or in part, at any
time or from time to time after the date on which Parent has accepted for
payment the Shares tendered pursuant to the Offer and prior to the termination
of this Agreement pursuant to Article VIII.  If Parent wishes to exercise the
Parent Option, Parent shall send a written notice to the Company (the "Exercise
                                                                       --------
Notice") specifying a date (not earlier than the next Business Day following the
- ------                                                                          
date such notice is given) for the closing of such purchase and containing a
representation by Parent that upon the issuance and delivery of the Option
Shares, there will be no further conditions precedent that need to be satisfied
for Parent and Merger Sub to effect the Merger, and that Parent and Merger Sub
will take all actions required on their respective parts to effect the Merger.

          (b) In the event of any change in the number of issued and outstanding
Shares by reason of any stock dividend, stock split, split-up, recapitalization,
merger or other change in the corporate or capital structure of the Company, the
number of Option Shares and the Option Price shall be appropriately adjusted to
restore Parent to its rights hereunder.

          (c) The Company's obligation to issue and deliver the Option Shares
upon exercise of the Parent Option is subject only to the following conditions:

              (i) No preliminary or permanent injunction or other order issued
by any federal or state court of competent jurisdiction in the United States
prohibiting the delivery of the Option Shares shall be in effect;

                                       34
<PAGE>
 
          (ii)   Any applicable waiting periods under the HSR Act, or other
applicable United States or foreign Laws shall have expired or been terminated;
and

          (iii)  The number of Option Shares plus the number of Shares accepted
for payment by Parent pursuant to the Offer will, upon issuance of the Option
Shares, constitute at least ninety percent (90%) of the Company's issued and
outstanding shares of Common Stock.

     (d) Any closing hereunder shall take place on the date specified by Parent
in its Exercise Notice delivered pursuant to subsection (a) above at 9:00 a.m.,
Pacific time, or the first day thereafter on which all of the conditions in
subsection (c) above are met, at the offices of Gibson, Dunn & Crutcher LLP, 333
South Grand Avenue, Los Angeles, California, or at such other time and places as
the parties may agree (the "Option Closing Date"). On the Option Closing Date,
                            -------------------                  
the Company will deliver to Parent a certificate or certificates representing
the Option Shares in the denominations designated by Parent in the Exercise
Notice and Parent will purchase such Option Shares from the Company at a price
per Option Share equal to the Option Price. Any payment made by Parent to the
Company pursuant to this subsection (d) shall be made by certified, cashier's or
bank check or by wire transfer of immediately available funds to an account
designated by the Company. The certificates representing the Option Shares may
bear an appropriate legend relating to the fact that such Option Shares have not
been registered under the Securities Act.

     6.14.  Use of Company Cash.  The Company agrees that prior to the initial
            -------------------                                               
Expiration Date it will take all steps reasonably necessary, after consulting
with Parent, to sell any marketable securities owned by it so that on the

                            CONDITIONS OF THE OFFER

     Notwithstanding any other provision of the Offer or this Agreement, and
subject to any applicable rules and regulations of the SEC, including Rule 14e-
1(c) relating to Parent's obligation to pay for or return tendered shares after
termination or withdrawal of the Offer, Parent shall not be required to accept
for payment or pay for any Shares tendered pursuant to the Offer, shall delay
the acceptance for payment of any Shares and if required by Section 1.1(b) of
this Agreement, shall extend the Offer by one or more extensions until December
31, 1998, as provided in Section 1.1(b) of the Agreement, and, except as
otherwise provided in this Agreement, may terminate the Offer at any time after
December 31, 1998 if (i) less than the number of Shares necessary to satisfy the
Minimum Condition have been tendered pursuant to the Offer prior to the
expiration of the Offer and not withdrawn; (ii) any applicable waiting period
under the HSR Act has not expired or terminated prior to the Expiration Date of
the Offer; or (iii) at any time after the date of this Agreement, and before
acceptance for payment of any Shares, any of the following events shall occur
and be continuing on or after December 31, 1998:

     (a) there shall have been any action taken, or any statute, rule,
regulation, judgment, order or injunction promulgated, entered, enforced,
enacted, issued or deemed applicable to the Offer or the Merger by any domestic
or foreign court or other Governmental Entity (other than the application of the
waiting period provisions of the HSR Act to the Offer or to the Merger) that, in
the reasonable judgment of Parent, would be expected to, directly or indirectly
(i) prohibit or impose any material limitations on, Parent's ownership or
operation of all or a material portion of the Company's businesses or assets, or
compel Parent to dispose of or hold separate any material portion of the
business or assets of the Company or Parent and its respective Subsidiaries, in
each case taken as a whole, (ii) prohibit, or make illegal, the acceptance for
payment, payment for or purchase of Shares or the consummation of the Offer, the
Merger or the other transactions contemplated by this Agreement, (iii) result in
the material delay in or restricts the ability of Parent, or renders Parent
unable, to accept for payment, pay for or purchase some or all of the Shares, or
(iv) impose material limitations on the ability of Parent effectively to
exercise full rights of ownership of the Shares, including the right to vote the
Shares purchased by it on all matters properly presented to the Company's
stockholders;

     (b) (i) the representations and warranties of the Company set forth in this
Agreement shall not be true and correct in any material respect as of the date
of this Agreement and as of consummation of the Offer as though made on or as of
such date (except for representations and warranties made as of a specified
date) but only if the respects in which the representations and warranties made
by the Company (without giving effect to any "materiality" limitations or
references to "material adverse effect" set forth therein) are inaccurate would
in the aggregate have a Company Material Adverse Effect, (ii) the Company shall
have failed to comply with its covenants and agreements contained in this
Agreement in all material respects which failure is likely to have a Company
Material Adverse Effect and, with respect to any breach or failure described in
clause (b)(i) or (b)(ii) above that can be cured, the breach or failure shall
not have been cured prior to ten (10) Business Days after Parent has furnished
the Company written notice 
<PAGE>
 
of such breach or failure, or (iii) there shall have occurred any events or
changes which have had or which are likely to have a Company Material Adverse
Effect;

     (c) the Board of Directors of the Company shall have withdrawn, or modified
or changed in a manner adverse to Parent (including by amendment of the Schedule
14D-9), its recommendation of the Offer, this Agreement or the Merger, or
recommended another proposal or offer for the acquisition of the Company, or the
Board of Directors of the Company, shall have resolved to do any of the
foregoing;

     (d) this Agreement shall have terminated in accordance with its terms; or

     (e) there shall have occurred and continue to exist (i) any general
suspension of, or limitation on prices for, trading in securities on the NYSE
(other than a shortening of trading hours or any coordinated trading halt
triggered solely as a result of a specified increase or decrease in a market
index), (ii) the declaration of any banking moratorium or any suspension of
payments in respect of banks, or any limitation (whether or not mandatory) by
any Governmental Entity on, or other event materially adversely affecting, the
extension of credit by lending institutions in the United States, or (iii) a
commencement of a war or armed hostilities directly involving the United States,
which has and continues to have a material adverse effect on the trading of
securities on the NYSE;

which in the reasonable judgment of Parent, in any such case, makes it
inadvisable to proceed with the Offer or the acceptance for payment of or
payment for the Shares.

     The foregoing conditions, other than condition (i) above, are for the sole
benefit of Parent and may be waived by Parent, in whole or in part at any time
and from time to time, in the sole discretion of Parent.  The failure by Parent
at any time to exercise any of the foregoing rights shall not be deemed a waiver
of any such right and each such right shall be deemed an ongoing right which may
be asserted at any time and from time to time, except as otherwise provided in
this Agreement.

               Services that are related or incidental to its Engineering and
               Construction Business, provided that (i) the use of the IT Group
               is not objected to by the client, (ii) the IT Group has adequate
               available personnel and other resources to timely and
               satisfactorily perform the work, and (iii) the IT Group proposed
               commercial terms are competitive with the market. For purposes of
               this Agreement, Fluor Daniel will evaluate the competitiveness of
               the IT Group's commercial terms by comparing them to terms and
               conditions of other providers of Environmental Services of the
               same quality and scope as the IT Group in the location where the
               services are to be provided, and reviewing them with the IT
               Group. The Steering Committee shall attempt to resolve any
               disagreements that may arise under this paragraph (b). In the
               event that anyone in the Fluor Daniel Group refuses to promote
               the use of the IT Group for such Environmental Services for a
               particular project because of one of the reasons set forth in
               clauses (i), (ii) or (iii) in this paragraph (b), the IT Group
               may promptly appeal such decision to the Steering Committee for
               reconsideration. The Steering Committee shall decide any such
               appeal promptly, or if practical, before the proposal or bid on
               the subject project is due.

          (c)  With respect to the types of projects referred to in paragraph
               (b), (c) and (d) of Section 1.5, the Parties agree that either
               Party may participate without the other in the types of projects
               set forth therein. The Parties recognize that there are potential
               benefits from working together in these areas, and therefore, the
               Parties shall explore mutually beneficial ways in which a Party
               may involve the other Party in such projects.

          (d)  The IT Group shall commit in Good Faith and use its commercially
               reasonable efforts to perform such Environmental Services as may
               be requested by Fluor Daniel, but shall not be obligated to
               provide such 

                                       5
<PAGE>
 
               Environmental Services if there is a valid business reason for
               its refusal to perform such services.

          (e)  With any common clients the IT Group shall have the marketing
               lead for projects that primarily involve Environmental Services
               and Fluor Daniel shall have the marketing lead for projects that
               primarily involve Engineering and Construction Services, except
               as otherwise provided in Section 2.7, concerning ongoing
               activities.


     2.3 Fluor Daniel Notification. Fluor Daniel shall notify its management and
         -------------------------
     the management of its Affiliates of the marketing relationship formed
     between the Parties and of the obligations of the Fluor Daniel Group under
     this Agreement. Periodically throughout the term of this Agreement, Fluor
     Daniel will communicate with its management and the management of its
     Affiliates to remind them of the marketing relationship formed between the
     Parties and of the obligations of the Fluor Daniel Group under this
     Agreement.

     2.4 IT Notification. Within 30 days of the date of this Agreement, IT shall
         ---------------
     notify its management and the management of its Affiliates of the marketing
     relationship formed between the Parties and of the obligations of the IT
     Group under this Agreement. Periodically throughout the term of this
     Agreement, IT will communicate with its management and the management of
     its Affiliates to remind them of the marketing relationship formed between
     the Parties and of the obligations of the IT Group under this Agreement.

     2.5 Prior Review of Notification. Prior to either Party forwarding a
         ----------------------------
     written communication to their respective management pursuant to Sections
     2.3 and 2.4 above, the Party preparing to forward the communication shall
     give the other Party a reasonable opportunity to review and comment on the
     communication.

     2.6 Steering Committee. Fluor Daniel and IT shall each designate two senior
         ------------------
     executives to serve on a steering committee for joint efforts under this
     Agreement (the "Steering Committee"). The initial members of the Steering
     Committee shall be Dave Myers, Ron Peterson, Jim Mahoney and Phil
     Strawbridge. The Steering Committee shall meet periodically during the term
     of the Agreement to review the joint efforts of the Parties under this
     Agreement, to determine any future course of cooperation between the
     Parties and to make such other determinations as they may be called upon to
     make pursuant to the terms of this Agreement. The Steering Committee shall
     also discuss joint marketing opportunities and initiatives and may delegate
     to other executives within their respective organizations the
     responsibility to implement such opportunities and initiatives. The members
     of the Steering Committee and their delegates shall use commercially
     reasonable efforts to keep the others advised of their respective marketing
     efforts with common clients and, with respect to the foregoing, establish
     mutually acceptable communications procedures. The Steering Committee shall
     attempt to reach consensus on all matters, and in the absence of a
     consensus, shall make determinations by 

                                       6
<PAGE>
 
     majority vote. For the first three (3) months following the Effective Date,
     these representatives shall meet at least once a month. Following that
     initial period, the Steering Committee shall meet at least once each
     quarter during the first year and at least twice a year thereafter.

     2.7  Ongoing Activities
          ------------------

          (a)  Services to Fluor Daniel. Prior to the effective date of this
               ------------------------
               Agreement, FDGTI provided Environmental Services to members of
               the Fluor Daniel Group. Attached as Exhibit B is a summary of
                                                   ---------
               substantially all of the ongoing projects in which FDGTI is
               providing Environmental Services to the Fluor Daniel Group,
               including contract numbers and contact persons. From the
               effective date of this Agreement, and except as otherwise
               provided in Exhibit B, the terms and conditions previously agreed
                           ---------
               to between the Parties for all projects ongoing shall govern. In
               the event the terms and conditions of this Agreement are not
               inconsistent with such previously agreed to terms and conditions,
               the terms set forth in this Agreement shall apply. The Steering
               Committee shall attempt to resolve any disagreements that may
               arise under this paragraph (a).

          (b)  Services to FDGTI. Prior to the effective date of this Agreement,
               -----------------
               the Fluor Daniel Group provided Engineering and Construction
               Services and certain Environmental Services to FDGTI. Attached as
               Exhibit C is a summary of substantially all of the ongoing
               ---------
               projects in which the Fluor Daniel Group is providing Engineering
               and Construction Services or Environmental Services to FDGTI,
               including contract numbers and contact persons. From the
               effective date of this Agreement, and except as otherwise
               provided in Exhibit C, the terms and conditions previously agreed
                           ---------
               to between the Parties for all ongoing projects shall govern. In
               the event the terms and conditions of this Agreement are not
               inconsistent with such previously agreed to terms and conditions,
               the terms set forth in this Agreement shall apply. FDGTI wishes
               to self perform all ongoing administrative support services
               presently provided by Fluor Daniel and to that end agrees to
               transition such services to FDGTI or its designee promptly, and
               in no event later than six (6) months following the date of this
               Agreement. During such transition, the provisions of Section 3.1
               shall apply to such administrative support services. The Steering
               Committee shall attempt to resolve any disagreements that may
               arise under this paragraph (b).

          (c)  Existing Projects. The Parties understand that a number of the
               -----------------
               clients of the FDGTI Group view the previous involvement of the
               Fluor Daniel Group in the business of the FDGTI Group as a
               benefit to such clients. The Parties agree that it is in the best
               interests of the clients and the Parties to minimize disruption
               to such clients that may arise from the sale by the

                                       7
<PAGE>
 
               Fluor Daniel Group of its ownership interest in FDGTI.
               Accordingly, the Parties agree that they will work together in
               Good Faith to minimize any such possible disruption and to use
               commercially reasonable efforts to maintain for FDGTI its
               existing projects. Fluor Daniel shall not, however, be required
               by the terms of this Agreement to give any corporate guarantees
               or other contractual assurances to such clients.

          2.8  Possible Acquisitions.
               ---------------------

               (a)  Restrictions on Environmental Acquisitions. The Fluor Daniel
                    ------------------------------------------
                    Group shall not, during the term of this Agreement, acquire,
                    merge with, form a joint venture with or enter into a
                    business combination with any entity which is engaged
                    primarily in performing Environmental Services, without the
                    prior written consent of FDGTI; provided, however, that the
                                                    --------  -------
                    Fluor Daniel Group shall be permitted on a case-by-case
                    basis to team, joint venture or contract with any such
                    entity on any specific project (i) which the FDGTI Group
                    fails or refuses to perform or (ii) where the conditions set
                    forth in Section 2.2, paragraph (b), clauses (i), (ii) and
                    (iii) are not met.

               (b)  Non-Environmental Acquisitions. It is not the present
                    ------------------------------
                    intention of Fluor Daniel to acquire an Environmental
                    Services capability; however, in the event that during the
                    term of this Agreement, the Fluor Daniel Group consummates
                    an acquisition, merger, or consolidation ("Acquisition")
                    with any entity which is not engaged primarily in performing
                    the Environmental Services, but which performs Environmental
                    Services, the Fluor Daniel Group shall be permitted to
                    perform Environmental Services by, through or with such
                    entity instead of the FDGTI Group, which shall not be deemed
                    a breach or violation of this Agreement. Following any such
                    Acquisition, this Agreement shall continue on a
                    non-exclusive basis, and contracts in effect on the date of
                    the closing of such Acquisition between the FDGTI Group and
                    the Fluor Daniel Group shall continue, unless otherwise
                    agreed.

               (c)  Discussions on Divestiture. In the event the Fluor Daniel
                    --------------------------
                    Group commences preparation to consummate such an
                    Acquisition, it shall, subject to the limitations of any
                    applicable confidentiality agreements, discuss such
                    acquisition with the Steering Committee on a confidential
                    basis with a view to determining whether IT would have any
                    interest in considering the acquisition of such portion of
                    the target business which performs Environmental Services,
                    other than services for the United States Government, (the
                    "Environmental Portion") if any. If the Fluor Daniel Group
                    consummates any such Acquisition, it shall, for a period of
                    60 days following the entering into of a written agreement
                    to consummate such Acquisition, engage in Good Faith
                    discussions with IT regarding the divestiture and sale of
                    the Environmental Portion to IT. Such discussions 

                                       8
<PAGE>
 
                    shall be exclusively with IT during such period unless
                    otherwise agreed (the "No-shop Period"). Following the
                    expiration of the No-shop Period, unless IT and the Fluor
                    Daniel Group have reached an agreement, the Fluor Daniel
                    Group shall, for a period of 120 days, engage in a Good
                    Faith effort to divest the Environmental Portion on
                    commercially reasonable terms (in its discretion). In the
                    event that the Fluor Daniel Group has not within such
                    120-day period (a) entered an agreement to sell the
                    Environmental Portion, or (b) decided to liquidate or phase
                    out the business of the Environmental Portion, then the
                    Fluor Daniel Group shall give consideration to any request
                    by IT through the Steering Committee that the terms and
                    conditions of this Agreement should be adjusted to avoid an
                    inequitable hardship to IT resulting from any material
                    diminution of value of this Agreement arising from such
                    Acquisition; provided, however, that no such adjustment
                    shall be made without the express written agreement of all
                    Parties.

the performing Party, the requesting Party shall provide the performing Party

Party represents that it is totally familiar with the terms of the Prime
Contract and agrees to be bound by the same.

where the increase or decrease in the Services under a Work Release involves
items of Services to be performed on a time and material or other cost basis, or
on a basis of units of Services, in which event the performing Party shall be
compensated on such basis for all such items or units of Services performed
under a Work Release, whether there is an increase or decrease in such items or

necessarily incurred by the performing Party as a result of such decrease in the

prospective profits or reimbursement of prospective overhead, general expenses,
administrative expenses or damages (consequential or otherwise) because of such
decrease in the Request for Services.
