                    GZA GEOENVIRONMENTAL TECHNOLOGIES, INC.
                               320 NEEDHAM STREET
                    NEWTON UPPER FALLS, MASSACHUSETTS 02464

                                PROXY STATEMENT
     FOR THE SPECIAL MEETING IN LIEU OF THE ANNUAL MEETING OF STOCKHOLDERS
                        TO BE HELD ON NOVEMBER 9, 2000.

     This Proxy Statement and the enclosed Notice of Meeting and form of proxy
are being mailed to stockholders, on or about October 9, 2000, in connection
with the solicitation of proxies by the Board of Directors of GZA
GeoEnvironmental Technologies, Inc. ("GZA" or "the Company") for use at the
Special Meeting in Lieu of Annual Meeting of the Company, to be held at the
Sheraton Needham Hotel, 100 Cabot Street, Needham, Massachusetts at 10 a.m.,
Eastern Standard Time, on Thursday, November 9, 2000, and at any and all
adjournments thereof (the "Special Meeting").

     On September 25, 2000, the record date for the determination of
stockholders entitled to notice of and to vote at the Special Meeting, there
were outstanding and entitled to vote [       ] shares of the Company's common
stock, $.01 par value ("Common Stock"). Each share of Common Stock entitles its
record holder to one vote on each matter considered at the Special Meeting.

PROXIES

     Each copy of this Proxy Statement is accompanied by a form of proxy that is
being solicited by the Board of Directors of the Company (sometimes referred to
as the "Board" or the "Board of Directors"). Please complete the proxy form,
sign it, date it, and return it promptly in the enclosed envelope. At the
Special Meeting, the persons who are named as proxies in properly executed
proxies in this form will vote the proxy shares in accordance with the
instructions indicated in the proxies. If you do not specify a choice in your
proxy, then the shares covered by the proxy will be voted as recommended by the
Board of Directors: that is, FOR the approval of the merger and FOR the election
of William S. Zoino, William R. Beloff and Lewis Mandell as the Class II
directors of the Company.

     We do not expect to ask you to vote on any other matters at the Special
Meeting. However, if any other matters are properly presented at the meeting for
consideration, the holder of the proxies will have discretion to vote on these
matters in accordance with their best judgment, which may include voting to
adjourn the meeting in order to solicit additional proxies. Proxies voting
against a specific proposal may not be used by the holder to vote for
adjournment of the meeting for the purpose of giving the holder additional time
to solicit votes in favor of that proposal.

     If you return a signed and dated proxy, you may revoke the proxy at any
time before it is voted by (i) notifying the Company's Secretary in writing,
(ii) signing and duly delivering a proxy bearing a later date or (iii) attending
the Special Meeting and voting in person. The Company's principal executive
offices are located at 320 Needham Street, Newton Upper Falls, Massachusetts
02464.

QUORUM AND TABULATION OF VOTES

     Under the Company's Amended and Restated By-Laws, the holders of a majority
of the shares of Common Stock issued, outstanding and entitled to vote at the
Special Meeting will constitute a quorum for the transaction of business at the
Special Meeting. Shares of Common Stock present in person or represented by
proxy (including shares that abstain or do not vote with respect to the matter
presented for stockholder approval) will be counted for the purpose of
determining whether a quorum exists at the Special Meeting. Holders of Common
Stock are entitled to one vote for each share held on each matter submitted to a
vote. The following shares will not be counted as votes cast in favor of a given
matter: (i) shares that abstain from voting as to that matter; and (ii) shares
held in "street name" by brokers or nominees who indicate on their proxies that
they do not have discretionary authority to vote the shares as to that matter
("broker non-votes"). Each matter will be tabulated separately. Votes will be
tabulated by the Company's transfer agent and registrar, American Stock Transfer
& Trust Company.

                              PROPOSAL ONE: MERGER

                               SUMMARY TERM SHEET

     This Summary Term Sheet highlights selected information contained in this
Proxy Statement and may not contain all of the information that is important to
you. We urge you to read this entire Proxy Statement carefully, including the
appendices. When we refer to "GZA" or the "Company" in this Proxy Statement we
mean to include (unless it doesn't fit the context), GZA GeoEnvironmental
Technologies, Inc. and its direct and indirect subsidiaries, including GZA
GeoEnvironmental, Inc. ("GZA GeoEnvironmental") and GZA Drilling, Inc. ("GZA
Drilling").

     - Stockholder vote:  You are being asked to approve and adopt the merger
       agreement and the transactions contemplated by the merger agreement, by
       which GeoEnvironmental Acquisition, Inc. will be merged with and into GZA
       (the "Merger Agreement"). See "THE MERGER AGREEMENT". The Merger
       Agreement must be approved and adopted by the affirmative vote of a
       majority of the outstanding shares of GZA Common Stock, and by the
       holders of at least 66 2/3% of the outstanding shares of GZA Common Stock
       that are not owned by Futureco Environmental, Inc. (as ownership for that
       purpose is defined in Section 203 of the Delaware General Corporation
       Law). See "THE SPECIAL MEETING."

     - Payment:  In the merger, each share of GZA Common Stock owned by GZA's
       current stockholders (other than certain shares owned by participating
       employees and selling stockholders, as described in more detail later in
       this Proxy Statement) will be converted into the right to receive $6.40
       in cash, without interest or other payment thereon. You will not own any
       GZA Common Stock after completion of the merger. See "THE MERGER
       AGREEMENT."

     - Parties:  The parties to the Merger Agreement are GZA, Futureco
       Environmental, Inc. and GeoEnvironmental Acquisition, Inc., which is
       sometimes referred to in this Proxy Statement as the "Merger Subsidiary."
       The Merger Subsidiary is a newly-formed Delaware corporation wholly owned
       by Futureco Environmental, Inc., which is sometimes referred to in this
       Proxy Statement as "Futureco." Futureco is a newly-formed Delaware
       corporation whose officers, directors and stockholders are also officers,
       directors or stockholders of GZA. See "SUMMARY--The Companies," and
       "INFORMATION ABOUT FUTURECO."

     - Participating executives and employees:  Five members of GZA's
       management, William R. Beloff, Joseph P. Hehir, Lawrence Feldman, William
       E. Hadge and M. Joseph Celi, are stockholders of Futureco. Messrs. Celi
       and Hadge are also directors of GZA. We refer to the members of GZA's
       management who are stockholders of Futureco as the "participating
       executives." We expect that a number of existing employees of GZA
       (including the participating executives) will also invest in Futureco
       prior to the effective time of the merger. Depending upon the number of
       shares of GZA Common Stock and options to acquire GZA Common Stock that
       each employee owns, he or she may elect to make the investment in
       Futureco at least in part by an exchange of GZA shares for Futureco
       shares and/or an exchange of GZA options for Futureco options. Those GZA
       shares that will be exchanged for Futureco shares are called "excluded
       shares" and the options that will be exchanged for Futureco options are
       referred to as "excluded options." Neither the excluded shares nor the
       excluded options will be converted into cash. Those employees who
       exchange GZA shares or options are referred to as "participating
       employees." Participating employees may own both excluded shares and
       excluded options as well as shares and options which are converted into
       the cash merger consideration. The participating executives and
       participating employees may have interests that are different from, or in
       addition to, your interests as a GZA stockholder generally. See "SPECIAL
       FACTORS -- Interests of Certain GZA Directors, Officers and Stockholders
       in the Merger."

     - Selling stockholders:  In addition, three GZA stockholders, including
       Donald T. Goldberg, who is the Chairman of our Board of Directors,
       William S. Zoino, who is a nominee for election as a Director at this
       Special Meeting, and John E. Ayres, who is an executive officer of GZA,
       have agreed to sell an aggregate of approximately 612,893 shares of GZA
       Common Stock to Futureco in connection with the

                                        2
<PAGE>   5

       merger at a purchase price equal to $5.76 per share, and have also agreed
       to vote their shares in favor of the merger. These stockholders are
       sometimes referred to in this Proxy Statement as the "selling
       stockholders." The selling stockholders may also have interests that are
       different from your interests as a GZA stockholder generally. See
       "SPECIAL FACTORS -- Interests of Certain GZA Directors, Officers and
       Stockholders in the Merger."

     - Tax consequences:  Generally, the merger will be taxable for U.S. Federal
       income tax purposes. You will recognize taxable gain or loss in the
       amount of the difference between $6.40 and your adjusted tax basis for
       each share of GZA Common Stock that you own that is exchanged for cash in
       the merger. See "SPECIAL FACTORS  -- Material Federal Income Tax
       Consequences to Stockholders."

     - Conditions:  The Merger Agreement and the transactions contemplated by
       the Merger Agreement are subject to GZA stockholder approval as well as
       other conditions, including Futureco's obtaining the necessary financing
       to complete the merger and the parties' obtaining necessary consents and
       approvals. See "THE MERGER AGREEMENT -- Closing Conditions."

     - After the merger:  Upon completion of the merger, Futureco will own 100%
       of GZA. The participating executives will own approximately 24% of
       Futureco, on a fully diluted basis. And the other participating employees
       will own the remaining shares of Futureco. See "SPECIAL FACTORS --
       Interests of Certain GZA Directors, Officers and Stockholders in the
       Merger."

QUESTIONS AND ANSWERS ABOUT THE MERGER

     The following questions and answers are for your convenience only, and
briefly address some commonly asked questions about the merger. You should still
carefully read this entire Proxy Statement, including the attached appendices.

Q:  WHAT AM I BEING ASKED TO VOTE UPON?

A:  You are being asked to approve and adopt a merger agreement that provides
    for the Merger Subsidiary to be merged with and into GZA. The Merger
    Subsidiary is a newly formed Delaware corporation wholly owned by Futureco.
    Futureco is a newly formed Delaware corporation whose officers, directors
    and stockholders are also officers, directors or stockholders of GZA. If
    this merger agreement (the "Merger Agreement") is approved and adopted, we
    will no longer be a publicly-held corporation and you will no longer own GZA
    Common Stock.

Q:  WHAT WILL I RECEIVE FOR MY GZA COMMON STOCK IF THE MERGER IS COMPLETED?

A:  You will be entitled to receive $6.40 per share in cash for each share of
    GZA Common Stock you hold at the time of the merger. If you have
    certificates for your GZA shares, you will be required to turn them in to
    qualify for the payment. The paying agent or the surviving corporation will
    be entitled to deduct and withhold certain taxes. If you hold shares in
    "street name," your broker should help you with the paperwork to obtain your
    payment. If you exercise your appraisal rights under Delaware law (see "WHAT
    RIGHTS DO I HAVE TO DISSENT FROM THE MERGER?"), you may be entitled to the
    appraised value of your shares, which may be more or less than the merger
    price.

Q:  WHY IS THE BOARD OF DIRECTORS RECOMMENDING THAT I VOTE IN FAVOR OF THE
    MERGER AGREEMENT?

A:  Acting upon the unanimous recommendation of a special committee of the Board
    of Directors consisting solely of directors who are not officers or
    employees of GZA and who have no financial interest in the proposed merger
    that is different from that of GZA stockholders generally (the "Special
    Committee"), the Board of Directors has unanimously determined that the
    terms of the merger are advisable, and are fair to, and in the best
    interests of, GZA stockholders. The Board of Directors and the Special
    Committee unanimously recommend that you vote FOR the approval and adoption
    of the Merger Agreement and the transactions contemplated by the Merger
    Agreement.

                                        3
<PAGE>   6

Q:  WHAT WILL HAPPEN TO PRESENT MEMBERS OF MANAGEMENT?

A:  We expect most members of our current management to continue to be employed
    by GZA. However, immediately following the merger, the officers of the
    Merger Subsidiary will become the officers of GZA, and the directors of the
    Merger Subsidiary will become the directors of GZA. Members of GZA
    management will be entitled to receive $6.40 per share in cash for each of
    their shares of GZA Common Stock, other than any excluded shares held by the
    participating executives or shares that the selling stockholders have agreed
    to sell to Futureco in connection with the merger. GZA employees will
    receive an amount equal to the difference, if any, between $6.40 per share
    and the per share exercise price for any outstanding options that they hold,
    other than excluded options, which will be converted into options to
    purchase Futureco common stock. The paying agent or the surviving
    corporation will be entitled to deduct and withhold certain taxes for those
    entitled to payment. Upon completion of the merger, Futureco will own 100%
    of GZA. The participating executives will own approximately 24% of Futureco,
    and the other participating employees will own the remaining shares of
    Futureco.

Q.  IS THE MERGER SUBJECT TO ANY CONDITIONS OTHER THAN RECEIVING THE REQUISITE
    STOCKHOLDER APPROVAL?

A:  Yes. Before completion of the transactions contemplated by the Merger
    Agreement, GZA, Futureco and the Merger Subsidiary must fulfill or waive
    several closing conditions. These conditions include, among others,
    Futureco's obtaining all financing necessary to complete the transactions
    contemplated by the Merger Agreement, on terms acceptable to Futureco. If
    these conditions are not satisfied or waived, the merger will not be
    completed even if the stockholders vote to approve and adopt the Merger
    Agreement.

Q:  WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A:  We are working toward completing the merger as quickly as possible. If the
    conditions to the merger are satisfied or waived, we hope to complete the
    merger in November 2000.

Q:  WILL I OWE ANY U.S. FEDERAL INCOME TAX AS A RESULT OF THE MERGER?

A:  The receipt of cash for shares of GZA Common Stock in the merger will be a
    taxable transaction for U.S. Federal income tax purposes and may also be a
    taxable transaction under applicable state, local, foreign or other tax
    laws. Generally, you will recognize gain or loss for these purposes equal to
    the difference between $6.40 per share and your tax basis for the shares of
    GZA Common Stock that you owned immediately before the merger. For U.S.
    Federal income tax purposes, this gain or loss generally would be a capital
    gain or loss if you held the shares as a capital asset. The receipt of cash
    for shares of GZA Common Stock acquired by GZA employees through the
    exercise of stock options may result in recognition by such employees of
    ordinary income depending on how long the shares have been held by the
    employee.

    TAX MATTERS ARE COMPLICATED AND THE TAX CONSEQUENCES OF THE MERGER TO YOU
    WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR TAX
    ADVISOR FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES OF THE MERGER TO
    YOU.

Q:  WHEN AND WHERE IS THE SPECIAL MEETING?

A:  The Special Meeting of GZA stockholders will be held at 10:00 a.m., Eastern
    Standard Time, on Thursday, November 9, 2000 at the Sheraton Needham Hotel,
    100 Cabot Street, Needham, Massachusetts.

Q:  WHO CAN VOTE ON THE MERGER AGREEMENT?

A:  Holders of GZA Common Stock at the close of business on September 25, 2000,
    the record date for the Special Meeting, may vote in person or by proxy at
    the Special Meeting.

                                        4
<PAGE>   7

Q:  WHAT VOTE IS REQUIRED TO APPROVE AND ADOPT THE MERGER AGREEMENT AND THE
    TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT?

A:  The Merger Agreement and the transactions contemplated by the Merger
    Agreement must be approved and adopted by the affirmative vote of at least a
    majority of the outstanding shares of GZA Common Stock, and at least 66 2/3%
    of the outstanding shares of GZA Common Stock that are not owned by
    Futureco, within the meaning of Section 203 of the Delaware General
    Corporation Law. At the record date for the Special Meeting, [     ] shares
    of GZA Common Stock were outstanding. GZA has been informed that
    [                                  ] of those shares are owned by Futureco
    within the meaning of Section 203.

Q:  WHAT DO I NEED TO DO NOW?

A:  After you have carefully reviewed this Proxy Statement, including the
    attached appendices, please mark your vote on your proxy card and sign and
    mail it in the enclosed return envelope as soon as possible. This will
    ensure that your shares will be represented at the Special Meeting. If you
    sign and send in the proxy card and do not indicate how you want to vote,
    your proxy will be voted FOR the approval and adoption of the Merger
    Agreement and the transactions contemplated by the Merger Agreement. If you
    do not vote by either sending in your proxy card or voting in person at the
    Special Meeting, it will have the same effect as a vote AGAINST the approval
    and adoption of the Merger Agreement and the transactions contemplated by
    the Merger Agreement.

Q:  IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
    SHARES FOR ME?

A:  Your broker will vote your shares only if you provide your broker with
    written instructions as to how to vote your shares. You should follow the
    directions provided by your broker regarding how to instruct your broker to
    vote your shares. Without instructions, your shares will not be voted by
    your broker and the failure to vote will have the same effect as a vote
    AGAINST the approval and adoption of the Merger Agreement and the
    transactions contemplated by the Merger Agreement. If you wish to attend the
    Special Meeting and vote in person, you must first obtain a legal proxy from
    your broker.

Q.  WHAT RIGHTS DO I HAVE TO DISSENT FROM THE MERGER?

A:  If you wish, you may dissent from the merger and seek an appraisal of the
    fair value of your shares, but only if you comply with all requirements of
    Delaware law summarized in "SPECIAL FACTORS--Dissenters' Rights of
    Appraisal" and attached as Appendix C of this Proxy Statement. Based on the
    determination of the Delaware Court of Chancery, the appraised fair value of
    your GZA shares of Common Stock, which will be paid to you if you seek an
    appraisal, may be more than, less than or equal to the $6.40 per share to be
    paid in the merger.

Q:  CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A:  Yes. You can change your vote at any time before the vote is taken at the
    Special Meeting. If you are the record holder of your shares, you can do
    this in one of the following three ways:

     - You can send a written notice dated later than your proxy card stating
       that you would like to revoke your current proxy.

     - You can complete and submit a new proxy card dated later than your
       original proxy card.

       If you choose either of the above two methods, you must submit your
       notice of revocation or your new proxy card to the Secretary of GZA at
       320 Needham Street, Newton Upper Falls, Massachusetts 02464. GZA must
       receive the notice or new proxy card before the vote is taken at the
       Special Meeting.

     - You can attend the Special Meeting and vote in person. Simply attending
       the Special Meeting and not voting, however, will not revoke your proxy.

     If you hold your shares in "street name" and have instructed a broker to
     vote your shares, you must follow the directions received from your broker
     as to how to change your vote.

Q:  SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A:  No. If the merger is completed, we will promptly send you written
    instructions for how you should send in your stock certificates in exchange
    for the $6.40 per share cash payment for your shares.

Q:  WHO CAN HELP ANSWER MY QUESTIONS?

     Futureco was incorporated in Delaware on March 6, 2000 and is qualified as
a foreign corporation in Massachusetts. Futureco has not carried on any

furtherance of the merger, including but not limited to, entering into certain

"INFORMATION ABOUT FUTURECO."

GeoEnvironmental Acquisition, Inc.

     The Merger Subsidiary, a newly formed Delaware corporation, was formed
solely for the purpose of completing the merger. The Merger Subsidiary is wholly
owned by Futureco. It has not carried on any activities to date other than those
activities incident to its formation and as contemplated by the Merger
Agreement.

     We sometimes refer to Futureco, the Merger Subsidiary, and certain persons
who may be considered to control these companies, identified in "INFORMATION
ABOUT FUTURECO" collectively as the "Futureco Parties."

THE MERGER

     In the merger, each issued and outstanding share of GZA Common Stock will
be canceled and converted automatically into the right to receive $6.40 in cash,
without interest or any other payment thereon, with the following exceptions:
shares of GZA Common Stock held by Futureco, including any such shares acquired
from the participating employees and the selling stockholders, will remain
outstanding; treasury shares and shares of GZA Common Stock owned by any of
GZA's subsidiaries will be canceled; and shares held by dissenting stockholders
will be subject to appraisal in accordance with Delaware law.

OUR RECOMMENDATIONS TO STOCKHOLDERS; FAIRNESS OF THE MERGER

     The Board of Directors formed a special committee (the "Special
Committee"), which was given exclusive authority to evaluate acquisition and
other proposals from Futureco or other parties that might enhance the value of
GZA's Common Stock, to negotiate the terms of any proposed transaction, to
advise the Board of Directors as to whether or not to engage in the transaction
proposed by Futureco or any other transaction and to retain its own financial
advisor and its own legal counsel. The Special Committee has unanimously
determined that the terms of the merger are advisable, and are fair to, and in
the best interests of, GZA stockholders, and has recommended to the Board of
Directors that the Merger Agreement and the transactions contemplated by the
Merger Agreement be approved and adopted. The Special Committee consists solely
of directors who are not officers or employees of GZA, and who have no financial
interest in the proposed merger that is different from that of GZA stockholders
generally. The Board of Directors has also unanimously determined that the terms
of the merger are advisable, and are fair to, and in the best interests of, GZA
stockholders. THE BOARD OF DIRECTORS AND THE SPECIAL COMMITTEE TOGETHER
UNANIMOUSLY RECOMMEND THAT YOU VOTE FOR THE APPROVAL AND ADOPTION OF THE MERGER
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT. For
additional information regarding these recommendations, including the factors
upon which they were based, see "SPECIAL FACTORS -- Background of the Merger"
and "-- Recommendations of the Special Committee and Board of Directors;
Fairness of the Merger."

FAIRNESS OPINION

     On August 14, 2000, the Special Committee received an oral opinion from
Houlihan Lokey Howard & Zukin Capital that, based upon and subject to the
limitations, assumptions and qualifications set forth in their opinion, as of
the date of their opinion, the $6.40 per share cash consideration to be received
in the merger by GZA stockholders was fair, from a financial point of view. This
opinion was confirmed in writing on August 16, 2000. The full text of this
opinion dated August 16, 2000, is attached as Appendix B to this Proxy
Statement. We urge you to read this entire opinion carefully. We will sometimes
refer to Houlihan Lokey Howard & Zukin Capital in this Proxy Statement as
"Houlihan Lokey."

INTERESTS OF GZA DIRECTORS AND OFFICERS IN THE MERGER

     When considering the recommendation of GZA's Board of Directors with
respect to the merger, you should be aware that some of GZA's directors and
officers have interests that are different from, or in addition to, your
interests as a GZA stockholder. For example, the participating executives are
stockholders of Futureco and thus will retain an indirect equity interest in GZA
after completion of the merger. After the merger, the participating executives
are expected to own 100% of Futureco.

     Under the terms of the Merger Agreement, all outstanding stock options of
GZA granted to employees, consultants or directors of GZA, except excluded
options, will vest and, on completion of an option exercise agreement, each
option holder will receive an amount of cash equal to the difference between
$6.40 per share and the option exercise price. Excluded options held by the
participating employees will be exchanged for options to purchase Futureco
common stock.

     For more information on the interests of GZA officers and directors in the
merger, which may be different from, or in addition to, your interests as a GZA
stockholder, see "SPECIAL FACTORS -- Interests of Certain GZA Directors,
Officers and Stockholders in the Merger."

FINANCING FOR THE MERGER

     Futureco estimates that approximately $15 million of third-party financing
will initially be required to complete the merger and to pay its related fees
and expenses. Futureco has received and accepted a commitment letter to finance
the merger from KeyBank National Association, in an aggregate amount sufficient
to fund these requirements. The commitment is in the amount of $19.5 million,
$9.5 million of which is structured as a term loan facility and $10 million of
which is a revolving credit facility which can be borrowed, repaid and
re-borrowed. The borrowers of the loans will initially be Futureco and the
Merger Subsidiary. Upon the completion of the merger, GZA will assume these
liabilities of the Merger Subsidiary.
                                        8
<PAGE>   11

For additional information regarding the financing for the merger, see "SPECIAL
FACTORS -- Financing for the Merger."

RECORD DATE; VOTING POWER

     At the Special Meeting to be held on November 9, 2000, you will be entitled
to one vote for each share of GZA Common Stock you hold of record as of
September 25, 2000.

     The Merger Agreement must be approved and adopted by the affirmative vote
of at least a majority of the outstanding shares of GZA Common Stock, and of at
least 66 2/3% of the outstanding shares of GZA Common Stock not owned by
Futureco within the meaning of Section 203 of the Delaware General Corporation
Law. On the record date, there were [          ] shares of GZA Common Stock
entitled to vote at the Special Meeting. GZA has been advised by Futureco that
[          ] of those shares are owned by Futureco within the meaning of Section
203. For additional information concerning the effect of Section 203 of the
Delaware General Corporation Law on the merger, see "THE SPECIAL
MEETING -- Delaware Law Considerations."

     The selling stockholders and all GZA directors and executive officers have
indicated that they intend to vote all of their GZA Common Stock FOR the
approval and adoption of the Merger Agreement and the transactions contemplated
by the Merger Agreement.

     Futureco has entered into a purchase agreement with each of Donald T.
Goldberg, William S. Zoino, and John E. Ayres (the "selling stockholders"). As
amended, the agreements give Futureco the right to purchase a total of
approximately 612,893 shares of GZA Common Stock from them (together the
"Purchase Agreements"). The Purchase Agreements include commitments from the
selling stockholders to vote in favor of any merger proposed by Futureco.

     As of the record date for the Special Meeting, the selling stockholders and
GZA directors and executive officers held an aggregate of [          ] shares of
GZA Common Stock, representing approximately [     ]% of the total number of
shares of Common Stock entitled to vote at the Special Meeting. That total
includes [          ] shares that are not owned by Futureco within the meaning
of Section 203 of the Delaware law, or approximately [     ]% of the total
shares that are not owned by Futureco.

THE MERGER AGREEMENT

     The Merger Agreement, including the significant conditions to the closing
of the merger, is described in "THE MERGER AGREEMENT" and is attached as
Appendix A to this Proxy Statement. We encourage you to read carefully the
entire Merger Agreement, as it is the legal document that governs the merger.

APPRAISAL RIGHTS

     GZA is a corporation organized under Delaware law. Under Delaware law, if
you do not vote in favor of the merger and you follow all of the procedures for
demanding appraisal rights described in "SPECIAL FACTORS -- Dissenters' Rights
of Appraisal" and attached in Appendix C, you will receive a cash payment for
the "fair value" of your shares of Common Stock, as determined by the Delaware
Court of Chancery, instead of the $6.40 cash payment to be received by the
Public Stockholders of GZA (as defined in "SPECIAL FACTORS -- Summary of
Financial Analyses Performed by Houlihan Lokey") in connection with the merger.
The price determined by the Delaware Court of Chancery may be more than, the
same as or less than the $6.40 in cash you would have received for each of your
shares in the merger if you had not exercised your appraisal rights. Generally,
in order to exercise appraisal rights, among other things:

     - You must NOT vote in favor of the Merger Agreement and the transactions
       contemplated by the Merger Agreement; and

     - You must make a written demand for appraisal in compliance with Delaware
       law BEFORE the vote on the Merger Agreement and the transactions
       contemplated by the Merger Agreement.

                                        9
<PAGE>   12

     Merely voting against the Merger Agreement will not preserve your appraisal
rights under Delaware law. Appendix C to this Proxy Statement contains the
Delaware statute relating to your appraisal rights. IF YOU WANT TO EXERCISE YOUR
APPRAISAL RIGHTS, YOU ARE URGED TO READ AND CAREFULLY FOLLOW THE PROCEDURES
DESCRIBED IN "SPECIAL FACTORS -- Dissenters' Rights of Appraisal" AND ATTACHED
IN APPENDIX C. FAILURE TO TAKE ALL OF THE STEPS REQUIRED UNDER DELAWARE LAW MAY
RESULT IN THE LOSS OF YOUR APPRAISAL RIGHTS.

EFFECTS OF THE MERGER

     Upon completion of the merger, Futureco will own 100% of GZA. The
participating executives will own approximately 24% of Futureco, and Futureco
expects that other participating employees will own the remaining shares of
Futureco. You will no longer be a stockholder of GZA following the merger. GZA's
current stockholders, other than Futureco, will not participate in any future
earnings or losses and growth or decline of GZA. After the merger, GZA will be a
closely-held corporation. As a result, there will be no public market for GZA
Common Stock, and the GZA Common Stock will cease to be quoted on The Nasdaq
Stock Market. The registration of GZA Common Stock under the Securities Exchange
Act of 1934, as amended, which we refer to as the "Exchange Act," will be
terminated.

CONDITIONS TO THE MERGER

     We will complete the merger only if a number of conditions are satisfied or
waived, including, but not limited to, the following:

     - the Merger Agreement and the transactions contemplated by the Merger
       Agreement are affirmatively approved by the holders of a majority of the
       outstanding GZA Common Stock and by at least 66 2/3% of the shares of our
       outstanding Common Stock not owned by Futureco;

     - no injunctions or legal restraints prevent the completion of the merger
       and the transactions contemplated by the Merger Agreement;

     - the representations and warranties made by the parties must be materially
       true and correct as of the Closing Date (as defined in "THE MERGER
       AGREEMENT -- Closing of the Merger");

     - the parties have materially performed their respective obligations under
       the Merger Agreement;

     - GZA has not experienced any material adverse changes since the date of
       the Merger Agreement;

     - each of GZA and Futureco has delivered an opinion of counsel to the other
       that is satisfactory to the other;

     - Futureco has obtained the financing necessary to complete the merger and
       transactions contemplated in the Merger Agreement on terms acceptable to
       Futureco; Futureco has advised us that the terms of the financing
       commitment already obtained (except for certain financial covenants that
       have not yet been negotiated) are acceptable to Futureco. See "SPECIAL
       FACTORS -- Financing for the Merger";

     - at least one business day before the Closing Date, we have received duly
       executed stock option exercise agreements from all GZA stock option
       holders other than holders of excluded options; and

     - we have obtained all necessary consents and waivers from third parties.

     If all of the other conditions are not either satisfied or waived, the
merger will not be completed even if our stockholders vote to approve the merger
and there are no other legal restraints hindering its completion.

                                       10
<PAGE>   13

TERMINATION OF THE MERGER AGREEMENT

     GZA and Futureco may mutually agree in writing to terminate the Merger
Agreement at any time before the Certificate of Merger is accepted by the
Secretary of State of Delaware. In addition, either party may terminate the
Merger Agreement if, among other things:

     - the other party breaches certain conditions;

     - a government entity with legal authority prevents the completion of the
       merger in a non-appealable manner;

     - the closing conditions are not met by December 14, 2000. See "The MERGER
       AGREEMENT -- Closing Conditions;"

     - the merger is not completed, and the party seeking to terminate did not
       proximately contribute to the failure;

     - our stockholders do not approve the merger at the Special Meeting; or

     - our Board withdraws or modifies its approval of the merger in connection
       with a superior acquisition proposal. See "THE MERGER AGREEMENT -- GZA
       Covenants."

     In addition, Futureco may terminate the Merger Agreement if, among other
things:

     - we enter into a definitive agreement with respect to any other
       acquisition proposal. See "The MERGER AGREEMENT -- GZA Covenants;" or

     - more than five percent of our record stockholders are dissenting
       stockholders, as defined by Delaware law, as of the effective time.

     Termination of the Merger Agreement by either party may be before or after
stockholder approval. For additional information about termination, see "THE
MERGER AGREEMENT -- Termination, Amendment and Waiver."

WHAT HAPPENS IF GZA RECEIVES A BETTER OFFER

     The Merger Agreement provides that neither GZA nor any of its officers,
directors, employees, representatives or other agents will encourage, directly
or indirectly, any inquiries or proposals with respect to a merger, acquisition,
tender offer, or any other acquisition proposal other than the one contemplated
in the Merger Agreement, or provide any confidential information or otherwise
facilitate any acquisition proposal other than the one contemplated in the
Merger Agreement.

     However, the Special Committee or our Board of Directors may continue to
discuss acquisition proposals and to cooperate with any party initially
contacted by GZA before GZA entered into the Merger Agreement, provided that
such talks could lead to a "superior acquisition proposal;" and the Board or the
Special Committee may discuss unsolicited acquisition proposals and cooperate
with the parties making such proposals if the unsolicited acquisition proposals
could become "superior acquisition proposals," and if it would be a breach of
fiduciary duty not to pursue such discussions. In such instances GZA must notify
Futureco of the acquisition proposals and give Futureco a reasonable amount of
time in which to respond. "Superior acquisition proposals" are bona fide
acquisition proposals made by third parties, which the Special Committee
determines in good faith could be more financially favorable to GZA stockholders
than the merger and are capable of being completed within a reasonable period of
time. For additional information about how acquisition proposals will be handled
under the Merger Agreement, see "THE MERGER AGREEMENT -- GZA Covenants."

EXPENSE REIMBURSEMENT UPON TERMINATION

     If the Merger Agreement is terminated because our Board has withdrawn or
modified its approval or recommendation of the merger or has approved or
recommended, or we have entered into a definitive agreement with respect to,
another acquisition proposal, then we will be required to reimburse Futureco for
its
                                       11
<PAGE>   14

reasonable, actual expenses in connection with the proposed merger, up to a
maximum of $750,000. For additional information with respect to this expense
reimbursement and the conditions upon which they would be payable, see "THE
MERGER AGREEMENT -- Termination, Amendment and Waiver."

AMENDING THE MERGER AGREEMENT

     GZA, Futureco and the Merger Subsidiary may amend the Merger Agreement by
mutual written consent by action of the parties' boards of directors at any time
before the Certificate of Merger is filed with the Delaware Secretary of State.
However, following our stockholders' approval of the Merger Agreement, we cannot
amend the Merger Agreement without the further approval of our stockholders if
applicable law requires that our stockholders approve that amendment.

PRICE RANGE OF COMMON STOCK

     GZA Common Stock is quoted on The Nasdaq Stock Market. On March 30, 2000,
the last trading day before GZA's public announcement that it had received a
preliminary acquisition proposal from a management group, GZA's Common Stock
closed at $5.00 per share. On May 15, 2000, the last day of trades before GZA's
public announcement that it had entered into a nonbinding letter of intent with
Futureco regarding the proposed merger, GZA's Common Stock closed at $5.875 per
share. On August 16, 2000, the last trading day before GZA's public announcement
of the Merger Agreement, GZA Common Stock closed at $5.6719 per share.

                      SELECTED CONSOLIDATED FINANCIAL DATA

     The following table sets forth selected consolidated financial data for
each of the fiscal years in the five-year period ended February 29, 2000, and
for the three months ended May 31, 2000 and 1999. The selected consolidated
financial data presented below under the captions "Income Statement Data" for
each of the fiscal years in the five-year period ended February 29, 2000 and
"Balance Sheet Data" as of February 29, 2000, and February 28, 1999, 1998 and
1997, are derived from the consolidated financial statements of GZA and its
subsidiaries, which financial statements have been audited by
PricewaterhouseCoopers LLP, independent certified public accountants. The
unaudited selected consolidated financial data presented below under the
captions "Income Statement Data" and "Balance Sheet Data" as of and for the
three months ended May 31, 2000 and 1999, are derived from the unaudited
consolidated financial statements of GZA incorporated by reference in this Proxy
Statement from GZA's Quarterly Report on Form 10-Q for the three months ended
May 31, 2000. The financial data set forth below should be read in conjunction
with "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the Consolidated Financial Statements as of February 29, 2000
and for each of the years in the three-year period ended February 29, 2000 and
for the three months ended May 31, 2000. GZA's audited consolidated financial
statements as of February 29, 2000 and February 28, 1999, and for each of the
years in the three-year period ended February 29, 2000, and the report thereon,

     No pro forma data giving effect to the merger are provided because GZA does
not believe that pro forma information is material to stockholders in evaluating
the merger and the Merger Agreement because the merger consideration is all cash
and if the merger is completed, GZA's Public Stockholders will no longer have
any equity interest in GZA.

                              THE SPECIAL MEETING

DATE, TIME, PLACE AND RECORD DATE OF THE SPECIAL MEETING

     The Special Meeting of stockholders of GZA will be held on November 9,
2000, beginning at 10:00 a.m., Eastern Standard Time, at the Sheraton Needham
Hotel, 100 Cabot Street, Needham, Massachusetts. The accompanying proxy is being
solicited by our Board of Directors and is to be voted at the Special Meeting or
any adjournment(s) or postponement(s) thereof. The holders of record of our
Common Stock as of the close of business on September 25, 2000 are entitled to
receive notice of, and to vote at, the Special Meeting. On the record date,
there were [          ] shares of GZA Common Stock outstanding. No other voting
securities of GZA are outstanding.

PURPOSE

     At the Special Meeting, you are being asked to consider and vote upon the
approval and adoption of the Merger Agreement, which provides for the merger of
the Merger Subsidiary with and into GZA. You are also being asked to elect three
Class II directors to serve in the event that the merger is not approved. In the
merger, each issued and outstanding share of GZA Common Stock will be canceled
and converted automatically into the right to receive $6.40 in cash, without
interest or any other payment thereon, with the following exceptions: shares of
GZA Common Stock that are held by Futureco will be retained by Futureco;
treasury shares and shares of GZA Common Stock owned by any of GZA's
subsidiaries will be canceled; and shares held by dissenting stockholders will
be subject to appraisal in accordance with Delaware law.

     We do not expect to ask you to vote on any matters at the Special Meeting
other than those described in this Proxy Statement. However, if any other
matters are properly presented at the Special Meeting for consideration, the
holder of the proxies will have discretion to vote on these matters in
accordance with their best judgment, which may include voting to adjourn the
meeting to solicit additional proxies. Proxies voting against a specific
proposal may not be used by the holder to vote for adjournment of the Special
Meeting for the purpose of giving the holder additional time to solicit votes in
favor of that proposal.

VOTING INFORMATION

     Each outstanding share of our Common Stock is entitled to one vote. The
presence, in person or by proxy, of the holders of a majority of the outstanding
shares of our Common Stock entitled to vote at the Special Meeting is necessary
to constitute a quorum for the transaction of business at the Special Meeting.
The affirmative vote of the holders of a majority of the outstanding shares of
our Common Stock, and of at least 66 2/3% of the outstanding shares of our
Common Stock that are not owned by Futureco within the meaning of section 203 of
the Delaware General Corporation Law are required to approve and adopt the
Merger Agreement and the transactions contemplated by the Merger Agreement.

     The selling stockholders and the participating executives have agreed to
vote their shares to approve and adopt the Merger Agreement and the transactions
contemplated by the Merger Agreement. As of September 25, 2000, the selling
stockholders and the participating executives held [          ] shares,
representing approximately [     ]% of our outstanding Common Stock and
approximately [     ]% of the shares not owned by Futureco within the meaning of
section 203 of the Delaware law. See "SPECIAL FACTORS -- Interests of Certain
GZA Directors, Officers and Stockholders in the Merger."

     Brokers who hold shares in "street name" for customers have the authority
to vote on "routine" proposals when they have not received instructions from
beneficial owners. However, absent specific instructions from the beneficial
owner of the shares, brokers are not allowed to exercise their voting discretion
with respect to the approval and adoption of non-routine matters such as the
merger. Abstentions and properly executed broker non-votes will be treated as
shares that are present and entitled to vote at the Special Meeting for purposes
of determining whether a quorum exists, but will have the same effect as votes
AGAINST the

                                       15
<PAGE>   18

approval and adoption of the Merger Agreement and the transactions contemplated
by the Merger Agreement.

DELAWARE LAW CONSIDERATIONS

     Section 203 of the Delaware General Corporation Law, entitled "Business
Combinations with Interested Stockholders," provides that, with certain
exceptions, a Delaware corporation may not engage in a merger such as that
proposed in this Proxy Statement with a person or entity that became an
"interested stockholder" of the corporation within the three-year period
preceding the transaction, unless the merger is authorized by the affirmative
vote of at least two-thirds of the outstanding voting stock of the corporation
that is not owned by the interested stockholder. GZA's Board of Directors
believes that Futureco became an interested stockholder by virtue of its having
during the three-year period acquired or agreed to acquire more than 15% of the
outstanding voting stock of GZA. For purposes of Section 203, a person is deemed
to "own" stock that it owns beneficially, either directly or indirectly, or that
it has the right to acquire pursuant to any agreement, arrangement or
understanding, or if it has any agreement, arrangement or understanding to
acquire, vote or dispose of the stock. Futureco has advised us that as of
September 25, 2000, the record date for the Special Meeting, Futureco owns
(within the meaning of Section 203) [          ] shares of GZA Common Stock.
Thus, the affirmative vote of at least [          ] shares of GZA Common Stock
not owned by Futureco representing two-thirds of the shares of GZA Common Stock
outstanding on that date and not owned by Futureco, will be required to
authorize the merger. For additional information about Futureco and its
ownership of GZA Common Stock, see "INFORMATION ABOUT FUTURECO."

SOLICITATION, REVOCATION AND USE OF PROXIES

     Proxies are being solicited by and on behalf of GZA's Board of Directors.
We will pay the costs of soliciting proxies from our stockholders as well as all
mailing and Securities and Exchange Commission ("Commission") filing fees
incurred in connection with this Proxy Statement. GZA has engaged the services
of D.F. King, to solicit proxies and to assist in the distribution of proxy
materials. In connection with its retention by GZA, D.F. King agreed to provide
solicitation services with respect to banks, brokers, institutional investors
and individual stockholders. GZA has agreed to pay D.F. King a fee of $7,500
plus a stated amount for each telephone call made by D.F. King, and to reimburse
its reasonable out-of-pocket expenses and to indemnify it against certain
liabilities and expenses, including liabilities and expenses under the Federal
securities laws. In addition to the solicitation of proxies by mail, some of our
directors, officers and employees may solicit proxies by telephone, facsimile
and personal contact, without separate compensation for those activities. Copies
of solicitation materials will be furnished to fiduciaries, custodians and
brokerage houses for forwarding to beneficial owners of Common Stock, and these
persons will be reimbursed for their reasonable out-of-pocket expenses.

     The grant of a proxy on the enclosed form does not preclude you from
attending the Special Meeting and voting in person. You may revoke your proxy at
any time before it is voted at the Special Meeting. If you are a record holder,
you may revoke your proxy by:

     - delivering to the Secretary of GZA, before the vote is taken at the
       Special Meeting, a written notice of revocation bearing a later date than
       the proxy;

     - duly executing a later dated proxy relating to the same shares of Common
       Stock and delivering it to the Secretary of GZA before the vote is taken
       at the Special Meeting; or

     - attending the Special Meeting and voting in person.

     Attendance at the Special Meeting will not in and of itself constitute a
revocation of a proxy. Any written notice of revocation or subsequent proxy
should be sent to the Secretary of GZA at 320 Needham Street, Newton Upper
Falls, Massachusetts 02464, or hand delivered to the Secretary of GZA before the
vote is taken at the Special Meeting. All valid proxies will be voted at the
Special Meeting in accordance with the instructions given. If no instructions
are given, the shares represented by the proxy will be voted at the Special

                                       16
<PAGE>   19

Meeting for approval and adoption of the Merger Agreement and the transactions
contemplated by the Merger Agreement. If you hold your shares in "street name"
and have instructed a broker to vote your shares, you must follow the directions
received from your broker as to how to change your vote. If you hold your shares
in "street name" and wish to vote in person at the Special Meeting, you must
first obtain a legal proxy from your broker.

     Stockholders who do not vote in favor of approval and adoption of the
Merger Agreement and the transactions contemplated by the Merger Agreement, and
who otherwise comply with the applicable statutory procedures of the Delaware
General Corporation Law summarized elsewhere in this Proxy Statement, will be
entitled to seek appraisal of the value of their Common Stock under Section 262
of the Delaware General Corporation Law. See "SPECIAL FACTORS -- Dissenters'
Rights of Appraisal."

     PLEASE DO NOT SEND IN YOUR STOCK CERTIFICATES AT THIS TIME. IN THE EVENT
THE MERGER IS COMPLETED, WE WILL SEND YOU INSTRUCTIONS REGARDING THE PROCEDURES
FOR EXCHANGING YOUR EXISTING STOCK CERTIFICATES FOR THE $6.40 PER SHARE CASH
PAYMENT.

                                SPECIAL FACTORS

BACKGROUND OF THE MERGER

     In May 1999, some members of GZA's senior management informed the Board of
Directors that a management group might be interested in acquiring the
outstanding Common Stock of GZA. At its May 17, 1999 meeting, the Board decided
that it would consider offers brought before the Board. The Board also sought
financial advice from Houlihan Lokey concerning the valuation of GZA's Common
Stock. During the following several months, some members of GZA's senior
management evaluated a potential management-led buyout; however, no formal
proposal was presented to the Board.

     In February 2000, the Board received a letter dated February 8 from Kelco
Acquisition Corp., a company unrelated to GZA or to any of GZA's officers or
directors, proposing a business combination whereby Kelco would acquire the
publicly-held shares of GZA's outstanding Common Stock for $5.00 per share in
cash, provided that shares held by senior management and certain affiliates of
GZA would be exchanged for shares of Kelco and subject to other stated
conditions. On February 14, the Board engaged Houlihan Lokey to advise it in
evaluating the proposal and considering strategic alternatives that might be
available. On February 22, the Board met, received advice from Houlihan Lokey,
and determined that the terms proposed by Kelco were inadequate and that it was
unlikely that the combination could be consummated as proposed. Accordingly, the
Board voted to decline the Kelco offer. At that meeting, the Board also decided
to consider adoption of a stockholders' rights plan and asked the President to
consult with GZA's outside counsel, Foley, Hoag & Eliot LLP (sometimes referred
to as "FH&E"), and with Houlihan Lokey and to prepare a recommended form of plan
for consideration at the Board's next meeting. At the conclusion of the meeting,
some members of GZA's senior management informed the Board that they were aware
of the Kelco offer and that they intended to form a management group to develop
and to present to the Board another proposal for a going-private transaction.
They said that they hoped to formulate the proposal within the next two weeks
and asked the Board to give the proposal careful consideration when it was
presented. After the management group left the meeting, the Board took no formal
action and made no commitment; but it was the sense of the meeting that any
management proposal, if presented, should be considered on its merits and in
context with any alternative courses that might be available at the time.

     On March 3, the Board met and reviewed a proposed form of stockholders'
rights plan. At the meeting, FH&E advised the Board on the principles of
corporation law and fiduciary duty applicable to adoption of rights plans and
similar actions that might be characterized as anti-takeover measures. Houlihan
Lokey presented an analysis of the possible economic effect of the proposed plan
and the basis of various assumptions as to the possible exercise price of the
rights and projected market prices for GZA's stock during the period

                                       17
<PAGE>   20

when rights might be outstanding. The Board decided to take no immediate action
but to consider the proposed plan and possible revisions of the proposed plan at
a later meeting or meetings. Mr. Perini then reported that he had been informed
by Messrs. Beloff and Celi that the management group expected to submit a
proposal by March 14. Accordingly, the Board voted to form a Special Committee
consisting of Messrs. Devitt, Mandell, Perini and Philbin and Ms. Giordano, all
the directors of GZA who were not and are not employees of GZA or associated
with any of the members of the management group. The Special Committee was
authorized on behalf of GZA to consider the management group's offer if and when
presented, to consider strategic alternatives that might be available to the
Company, and to make recommendations to the Board of Directors. The Special
Committee was also authorized in its discretion to engage legal counsel and
financial advisers.

     Following the Board meeting, the Special Committee met and elected Mr.
Perini its chair and Mr. Devitt its vice-chair. Thereafter, the Special
Committee engaged Houlihan Lokey as its financial adviser and the firm of
Epstein Becker & Green P.C. (sometimes referred to as "EB&G"), as its legal
counsel.

     On March 7, the management group sent a letter to the Special Committee
asking for an exclusivity period to present an acquisition proposal. On March
10, the Special Committee met and decided not to enter into a formal exclusivity
agreement.

     On March 21, Mr. Beloff and Mr. Celi, representing Futureco, presented to
Mr. Perini a draft letter of intent proposing that Futureco would acquire all
the outstanding shares of GZA Common Stock for cash at $5.65 per share. On March
22, the Special Committee met and authorized Mr. Perini and EB&G to negotiate
provisions of the proposed letter of intent, but the sense of the meeting was
that the price was too low. Mr. Perini informed Futureco that the proposed
letter of intent was not acceptable. On the same day, Futureco entered into the
Purchase Agreements with Messrs. Goldberg, Zoino, and Ayres providing for
Futureco's acquisition of their GZA holdings in the event that a business
combination were consummated.

     Acquisitor plc, a British investment group, filed a Schedule 13D statement
with the SEC reporting that on March 27 it had acquired 219,200 shares of GZA's
Common Stock, approximately 5.3% of the total shares outstanding.

     On March 31, GZA issued a press release announcing that its Board had
received a preliminary proposal for a management buyout for cash, that the
Special Committee had been organized and that the Special Committee had engaged
Houlihan Lokey and EB&G.

     On April 6, Futureco delivered a revised draft letter of intent providing
for a price of $6.10 per share of GZA Common Stock. During the next two weeks,
Mr. Perini and Mr. Devitt had numerous meetings and telephone conversations with
Messrs. Beloff, Celi, and Hadge, principals of Futureco; Houlihan Lokey had
several telephone conversations with Tucker Anthony Cleary Gull (sometimes
referred as "Tucker Anthony"), the financial advisor for Futureco; and EB&G had
numerous telephone conversations with Bowditch & Dewey (sometimes referred to as
"B&D"), legal counsel for Futureco. These meetings and conversations concerned
various provisions of the Futureco proposal, including principally the price,
the amount and application of a possible break-up fee, the terms of proposed
employment agreements between Futureco and principals who were then employed by
GZA, and procedures for seeking a "market test" of whether Futureco's proposed
terms were sufficiently attractive that other possible acquirors of GZA would
not be induced to offer better terms.

     On April 16, Tucker Anthony on behalf of Futureco communicated to Houlihan
Lokey a revised proposal for a buyout at $6.10 per share. On April 18, the
Special Committee determined that the $6.10 price was still too low.

     On April 19, the Special Committee met to receive status reports from Mr.
Perini, Mr. Devitt, Houlihan Lokey, and EB&G. The committee decided to continue
negotiations with Futureco with a view to improving the terms of the offer.

                                       18
<PAGE>   21

     On April 20, Messrs. Perini and Devitt participated in a telephone
conference with representatives of Futureco, Houlihan Lokey, and Tucker Anthony,
in which the participants discussed the need for a market test in order to
determine whether the proposed price would be fair in comparison with what other
possible acquirors might offer.

     On April 25, Messrs. Beloff, Celi, and Hadge communicated to Messrs. Perini
and Devitt a revised proposal at a price of $6.25 per share. On April 25 and 28,
the Special Committee met, decided that that price was inadequate, and
instructed Houlihan Lokey to investigate whether other parties might be
interested in making competing proposals. Meanwhile, the Special Committee and
its advisers continued to negotiate other provisions, including a proposed
break-up fee.

     During the first two weeks of May, Houlihan Lokey initiated discussions
with other persons who Houlihan Lokey believed might be interested in acquiring
GZA. As a result of those discussions, eventually seven parties executed
confidentiality agreements with GZA and were provided with detailed financial
and other information. Meanwhile, Mr. Perini and Mr. Devitt continued
discussions with Messrs. Beloff, Celi, and Hadge and EB&G continued discussions
with B&D concerning the terms and provisions of the revised proposed letter of
intent. On May 9, Futureco and Acquisitor plc entered into an agreement giving
Futureco the option to purchase all shares of GZA Common Stock held by
Acquisitor at a price equal to the greater of $6.25 per share or the final
merger price.

     On May 10, Mr. Perini and Mr. Devitt informed Messrs. Beloff, Celi, and
Hadge that Houlihan Lokey had initiated discussions with other prospective
purchasers. On May 15, Mr. Devitt informed Mr. Celi that the Special Committee
intended to suspend discussions with Futureco in view of the lack of progress in
the discussions since the April 25 offer was made. On May 15, Futureco sent to
the Special Committee a revised offer at $6.45 per share. On May 16, the Special
Committee met and voted to enter into a letter of intent at that price, subject
to negotiation of a definitive agreement, to approval by the full board and the
stockholders of GZA, completion of Futureco's financing arrangements, and to
there being no restriction on GZA's right to provide information to and to
continue discussions with other possible acquirors pending negotiation of the
definitive agreement. On May 17, the letter of intent was executed and GZA
issued a press release announcing that the letter of intent had been executed.

     During the remainder of May and June, EB&G and B&D negotiated the
provisions of a definitive merger agreement, while Houlihan Lokey pursued
discussions with other possible purchasers, including the seven who executed
confidentiality agreements. Ultimately, those discussions did not result in a
competing proposal by any of the other parties.

     On June 29, Mr. Celi told Mr. Devitt by telephone that financing concerns
relating to some of GZA's assets and contingent liabilities would require an
adjustment in Futureco's proposed price and that Futureco wanted a limitation on
the amount of GZA's transaction expenses that Futureco would assume. The
contingent items included primarily GZA's interest in a pending sale of a
brownfield development property, costs associated with the planned relocation of
GZA's offices and reorganization of some of its regional offices, and the impact
of GZA's discontinuing operation of its Information Services Division.

     On June 30, Futureco announced that its agreement with Acquisitor plc had
expired by its terms.

     On July 6, Mr. Devitt told Mr. Celi by telephone that the Special Committee
would instruct EB&G to discontinue negotiations with B&D in view of the lack of
progress toward a definitive agreement. He also suggested to Mr. Celi that the
Special Committee might accept a reduction of the price to $6.40 per share in
recognition of the contingent factors raised on June 29 and discussed
thereafter. He also stated that the Special Committee would not agree to revise
any other significant terms of the transaction, including the provisions for
payment of transaction expenses. On July 13, Mr. Beloff told Mr. Devitt by
telephone that Futureco would be prepared to proceed at a price of $6.40 per
share without revising any other material terms.

                                       19
<PAGE>   22

     On July 18, the Special Committee met and voted to present the transaction
for approval by the full Board of GZA as soon as the definitive agreement was
complete. EB&G and B&D continued negotiation of the definitive agreement for the
last two weeks of July and the first week of August.

     On August 14, 2000, the Special Committee met at the offices of GZA and
reviewed with EB&G the terms and conditions of the Merger Agreement and other
documents in substantially final form, as compared with the drafts previously
reviewed by the Special Committee. At the August 14, 2000 meeting, Houlihan
Lokey made a presentation to the Special Committee and advised the Special
Committee that, in its opinion, as of that date, based on and subject to the
limitations, assumptions and qualifications that are set forth in its written
opinion, the merger consideration of $6.40 per share in cash to be received by
the stockholders of GZA, was fair from a financial point of view. A discussion
with and questions to Houlihan Lokey by the Special Committee followed Houlihan
Lokey's presentation. EB&G reviewed applicable fiduciary duty standards with the
Special Committee members. The Special Committee then concluded that, in the
circumstances then existing, the $6.40 per share cash offer was, for GZA's
Public Stockholders, preferable to continuing to hold shares in the public
company, and represented the highest price Futureco was willing to pay. The
Special Committee discussed the terms of the Merger Agreement and the interests
of GZA's management employees in the transaction. After considering the matters
discussed, the Special Committee unanimously determined that the terms of the
merger are advisable, and are fair to, and in the best interests of, GZA's
Public Stockholders, and recommended to the Board of Directors and to GZA's
Public Stockholders that the Merger Agreement and the transactions contemplated
by the Merger Agreement be approved.

     Immediately following the August 14 meeting of the Special Committee, the
entire Board of Directors met at the offices of GZA. Houlihan Lokey discussed
its presentation and responded to questions from members of the Board of
Directors. EB&G responded to questions regarding the terms of the Merger
Agreement and other documents, and FH&E advised the Board of Directors with
respect to the fiduciary duties of the directors. The Board of Directors
discussed the terms of the Merger Agreement and the interests of GZA's
management employees in the transaction. After considering the matters presented
to the Board of Directors, the Board of Directors unanimously resolved that the
terms of the merger are advisable, and are fair to, and in the best interests
of, GZA's Public Stockholders, and recommended to GZA's Public Stockholders that
the Merger Agreement and the transactions contemplated by the Merger Agreement
be approved and adopted.

     On August 16, 2000, Houlihan Lokey delivered its written opinion to the
Board of Directors; and GZA, Futureco and the Merger Subsidiary entered into the
Merger Agreement, and on August 17 GZA issued a press release announcing the
execution of the Merger Agreement.

RECOMMENDATIONS OF THE SPECIAL COMMITTEE AND BOARD OF DIRECTORS; FAIRNESS OF THE
MERGER

     The Special Committee of the Board of Directors has unanimously determined
that the terms of the merger are advisable, and are fair to, and in the best
interests of, GZA's Public Stockholders. The Special Committee unanimously
recommended to the Board of Directors and GZA stockholders that the Merger
Agreement and the transactions contemplated by the Merger Agreement be approved
and adopted. The Special Committee considered a number of factors, as more fully
described above under "-- Background of the Merger" and as described below under
"-- Reasons for the Special Committee's Determination," in determining to
recommend that the Board of Directors and GZA stockholders approve the Merger
Agreement and the transactions contemplated by the Merger Agreement. The Board
of Directors, acting upon the recommendation of the Special Committee,
unanimously determined that the terms of the merger are advisable, and are fair
to, and in the best interests of, GZA's Public Stockholders. The Board of
Directors and the Special Committee unanimously recommend that you vote FOR the
approval and adoption of the Merger Agreement and the transactions contemplated
by the Merger Agreement.

     Reasons for the Special Committee's Determination.  In reaching its
recommendation, the Special Committee considered a number of factors, both
positive and negative, including the following material factors:

     - the financial and other terms of the Merger Agreement;

     - the business, results of operations, properties and financial condition
       of the Company and the nature of the industry in which it operates;

     - the history of the price of the shares of GZA Common Stock on The Nasdaq
       Stock Market over the past eighteen months and the recent daily trading
       volume in GZA's shares;

     - the discussions held by GZA with other companies regarding potential
       business combination transactions with GZA and the Special Committee's
       view, in light of these discussions, as to the likelihood of a superior
       proposal;

     - GZA's existing competitive and market position, including GZA's ability
       to effectively compete with companies having significantly greater
       financial resources than GZA;

     - the alternatives available to GZA in light of the consideration proposed
       to be received pursuant to the Merger Agreement, including continuing to
       maintain GZA as an independent company and not engaging in any
       extraordinary transaction, or engaging in an extraordinary transaction
       designed to increase the trading price for shares of GZA's Common Stock;

     - the financial presentation of Houlihan Lokey and its opinion as to the
       fairness, from a financial point of view, of the merger consideration to
       GZA's Public Stockholders;

     - the Special Committee's belief that $6.40 per share of Common Stock was
       the highest price that Futureco was willing to offer;

     - the absence of any proposals from unaffiliated third parties to buy the
       Company during the period since the filing of the Company's press release
       disclosing that it was considering various strategic alternatives;

     - the arm's-length nature of the negotiations between the Special Committee
       and its advisors with Futureco and its advisors, evidenced among other
       things by (i) the process of discussions regarding valuations of the
       Company and its securities and terms of a possible transaction; (ii) the
       Special Committee's rejection of several of Futureco's proposed offers;
       (iii) the price increases achieved by the Special Committee and its
       representatives; (iv) the fact that the initial draft of the Merger
       Agreement received from B&D reflected a majority of the terms that the
       Special Committee and its representatives believed would need to be
       included in any draft merger agreement; and (v) the significant
       improvements to the initial draft of the Merger Agreement that were
       negotiated by the Special Committee and its representatives;

     - the judgment that the price of $6.40 per share would adequately reflect
       the unaffiliated stockholders' loss of the opportunity to participate in
       any potential future growth of GZA; and

     - the availability to dissenting stockholders of appraisal rights under
       Section 262 of the Delaware General Corporation Law.

     The members of the Special Committee also determined that the merger is
procedurally fair because, among other things:

     - the Special Committee, consisting solely of directors who are not
       officers or employees of GZA, and who have no financial interest in the
       proposed merger different from GZA stockholders generally, had exclusive
       authority to consider, negotiate and evaluate the terms of any proposed
       transaction, including the merger;

                                       21
<PAGE>   24

     - none of the members of the Special Committee has or expects to have any
       financial interest in Futureco;

     - the Special Committee retained and received advice from independent legal
       counsel and financial advisors in negotiating and evaluating the terms of
       the Merger Agreement;

     - the $6.40 per share cash consideration and the other terms and conditions
       of the Merger Agreement resulted from arm's-length bargaining between the
       Special Committee and its representatives, on the one hand, and Futureco
       and its representatives, on the other hand; and

     - the affirmative vote of 66 2/3% the outstanding GZA Common Stock not
       owned by Futureco is required under Delaware law to approve and adopt the
       Merger Agreement and, under Delaware law, GZA stockholders have the right
       to dissent from the merger and demand an appraisal of the value of their
       shares.

     The foregoing discussion addresses the material information and factors
considered by the Special Committee in its consideration of the merger,
including factors that support the merger as well as those that may weigh
against it. In view of the variety of factors and the amount of information
considered, the Special Committee did not find it practicable to, and did not
specifically make assessments of, quantify or otherwise assign relative weights
to the various factors and analyses considered in reaching its determination.
The determination to approve the Merger Agreement and the transactions
contemplated by the Merger Agreement was made after consideration of all the
factors as a whole.

     Reasons for the Board of Directors' Determination.  In reaching its
decision to approve the Merger Agreement and the transactions contemplated by
the Merger Agreement, the Board of Directors relied on the Special Committee's
recommendation and the factors examined by the Special Committee as described
above. In view of the wide variety of factors considered in connection with its
evaluation of the proposed merger, the Board of Directors did not find it
practicable to quantify and did not quantify or otherwise attempt to assign
relative weights to the foregoing factors or determine that any factor was of
particular importance. Rather, the Board of Directors viewed its position as
being based on the totality of the information presented and considered by it.
In connection with its consideration of the determination by the Special
Committee, as part of its determination with respect to the merger, the Board of
Directors adopted the conclusion and the analysis underlying the conclusion of
the Special Committee, based upon its view as to the reasonableness of that
analysis.

     Fairness of the Merger to Unaffiliated Stockholders.  The Board of
Directors believes that the merger is substantively and procedurally fair to and
in the best interests of GZA's stockholders who are not affiliated with Futureco
for all of the reasons set forth above. In addition, with respect to procedural
fairness, the Board of Directors formed the Special Committee consisting of
directors of GZA, none of whom are officers or employees of GZA or have an
interest in the proposed merger different from that of GZA's unaffiliated
stockholders generally. The consideration of $6.40 in cash per share was the
highest price obtained following arm's length negotiations between the Special
Committee and representatives of Futureco.

     In reaching these conclusions, the Board of Directors considered it
significant that:

     - no member of the Special Committee has an interest in the proposed merger
       different from that of GZA's stockholders generally;

     - the Special Committee retained its own financial and legal advisors, who
       have extensive experience with transactions similar to the merger and who
       assisted the Special Committee in the negotiations with Futureco; and

     - Houlihan Lokey had been retained to advise the Special Committee as to
       the fairness, from a financial point of view, of the proposal received
       from Futureco or any third party, and Houlihan Lokey had reached the
       conclusions expressed in its written opinion dated August 16, 2000.

                                       22
<PAGE>   25

     The Board of Directors believes that the merger is procedurally fair to
GZA's Public Stockholders for all of the reasons and factors described above.

     Position of the Futureco Parties as to the Fairness of the Merger.  Under a
potential interpretation of the Exchange Act rules governing "going private"
transactions, Futureco and the Merger Subsidiary may be deemed to be affiliates
of GZA. The Futureco Parties are making the statements included in this
sub-section solely for the purposes of complying with the requirements of Rule
13e-3 and related rules under the Exchange Act. The Futureco Parties' position
as to the fairness of the merger is not a recommendation to any stockholder as
to how that stockholder should vote on the merger.

     The Futureco Parties believe that the merger is substantively and
procedurally fair to GZA's stockholders who are not affiliated with Futureco.
However, none of the Futureco Parties has undertaken any formal evaluation of
the fairness of the merger to GZA's unaffiliated stockholders. Moreover, the
Futureco Parties did not participate in the deliberations of the Special
Committee or receive advice from the Special Committee's financial advisor. The
Futureco Parties believe that the merger is substantively fair to GZA's
unaffiliated stockholders based on the current and historical market prices of
GZA's Common Stock. The Futureco Parties believe that the merger is procedurally
fair to GZA's unaffiliated stockholders because the Special Committee,
consisting solely of directors who are not officers or employees of GZA, and who
have no financial interest in the proposed merger different from GZA
stockholders generally, was given exclusive authority to, among other things,
consider, negotiate and evaluate the terms of any proposed transaction,
including the merger. The Futureco Parties also believe that the merger is
procedurally fair to GZA's unaffiliated stockholders, because the Merger
Agreement requires that the holders of two-thirds of GZA's shares that are not
owned by Futureco vote in favor of approval and adoption of the Merger Agreement
in order to complete the merger.

     Under a potential interpretation of the Exchange Act rules governing "going
private" transactions, one or more of the participating executives may be deemed
to be affiliates of GZA. The participating executives are making the statements
included in this sub-section solely for the purposes of complying with the
requirements of Rule 13e-3 and related rules under the Exchange Act. Although
the participating executives may have interests in the merger that are different
from, or in addition to, your interests as a GZA stockholder, each of the
participating executives, in his capacity as an officer of GZA, believes that
the merger is substantively and procedurally fair to GZA's unaffiliated
stockholders, in each case, based only on the limited facts and information
available to him.

     The participating executives did not participate in the deliberations of
the Special Committee. However the participating executives considered the same
factors examined by the Special Committee described above under "-- Reasons for
the Special Committee's Determination" and have adopted the conclusion and the
analysis underlying the conclusion of the Special Committee, based upon their
view as to the reasonableness of that analysis. In addition, Mr. Celi and Mr.
Hadge, as members of GZA's Board of Directors, participated in the consideration
of the merger transaction by the Board of Directors as discussed above under
"-- Reasons for the Board of Director's Determination." Based on these factors,
considered together, the participating executives believe that the merger is
substantively and procedurally fair to GZA's unaffiliated stockholders. The
participating executives believe that the merger is procedurally fair to GZA's
unaffiliated stockholders for all of the reasons and factors described above
under "-- Reasons for the Special Committee's Determination."

     The participating executives believe these analyses and factors provide a
reasonable basis upon which to form their belief that the merger is fair to
GZA's unaffiliated stockholders. This belief should not, however, be construed
as a recommendation to GZA's Public Stockholders by the participating executives
to vote to approve and adopt the Merger Agreement and the transactions
contemplated by the Merger Agreement.

OPINION OF FINANCIAL ADVISOR TO THE SPECIAL COMMITTEE

     The Special Committee asked Houlihan Lokey, in its role as financial
advisor to the Special Committee, to render an opinion as to the fairness from a
financial point of view to the stockholders of GZA of the consideration to be
received by the stockholders pursuant to the terms of the Merger Agreement.
Houlihan Lokey delivered to the Special Committee its written opinion, dated
August 16, 2000, to the effect that, as of that date, based on and subject to
the assumptions, limitations and qualifications set forth in its written
opinion, the consideration to be received by the holders of GZA Common Stock
pursuant to the Merger Agreement, was fair to the stockholders from a financial
point of view. The full text of Houlihan Lokey's opinion is attached as Appendix
B to this Proxy Statement. On October [9], 2000, Houlihan Lokey delivered to
GZA's Board of Directors a supplementary letter confirming that, based on an
updated analysis as of [September 30,] 2000 and subject to the same assumptions,
qualifications and limitations set forth in the Opinion, the consideration to be
received by GZA's Public Stockholder pursuant to the merger is fair to them from
a financial point of view.

SUMMARY OF FINANCIAL ANALYSES PERFORMED BY HOULIHAN LOKEY

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. The
following is a brief summary and general description of the valuation
methodologies utilized by Houlihan Lokey. The summary does not purport to be a
complete statement of the analyses and procedures applied, the judgments made or
the conclusion reached by Houlihan Lokey or a complete description of its
presentation. Houlihan Lokey believes, and so advised the Special Committee of
the Board and the Board, that its analyses must be considered as a whole and
that selecting portions of its analyses and of the factors considered by it,
without considering all factors and analyses, could create an incomplete view of
the process underlying its analyses and opinions.

     Houlihan Lokey understands that the Board of Directors of GZA received an
offer from Futureco to acquire all of the outstanding Common Stock of the
Company for $6.40 per share. Certain officers, directors or stockholders of
Futureco are also employees or stockholders of GZA. All other common
stockholders of GZA are referred to herein as the "Public Stockholders." Such
transaction and all related transactions are referred to collectively herein as
the "Transaction."

     Houlihan Lokey was retained to act as financial advisors to the Special
Committee of the Board regarding (i) negotiations with a management investment
group (the "MBO Group") for a potential acquisition of 100% of the outstanding
Common Stock of the Company and certain related transactions, (ii) a possible
sale or merger of GZA involving all or a substantial part of the business,
assets or equity interests of GZA and/or its subsidiaries and affiliates in one
or more transactions with an unaffiliated third party; and, (iii) if and when
requested by the Special Committee, providing an opinion to the Special
Committee and GZA's Board that the Transaction is fair to GZA's common
stockholders from a financial point of view. At the August 14, 2000 meeting of
the Board, Houlihan Lokey presented its analysis as hereinafter described and
delivered its oral opinion that as of such date and based on the matters
described therein, the Transaction is fair to the Public Stockholders of GZA
from a financial point of view. That oral opinion was subsequently confirmed by
a written opinion dated August 16, 2000.

     THE COMPLETE TEXT OF HOULIHAN LOKEY'S OPINION DATED AUGUST 16, 2000 IS
ATTACHED HERETO AS APPENDIX B. THE SUMMARY OF THE OPINION SET FORTH BELOW IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO SUCH OPINION. THE COMMON STOCKHOLDERS
ARE URGED TO READ SUCH OPINION CAREFULLY IN ITS ENTIRETY FOR A DESCRIPTION OF
THE PROCEDURES FOLLOWED, THE FACTORS CONSIDERED AND THE ASSUMPTIONS MADE BY
HOULIHAN LOKEY. HOULIHAN LOKEY'S WRITTEN OPINION IS FOR THE INFORMATION AND
ASSISTANCE OF THE BOARD AND DOES NOT CONSTITUTE A RECOMMENDATION AS TO HOW ANY
HOLDER OF COMMON STOCK OF GZA SHOULD VOTE WITH RESPECT TO THE TRANSACTION.

                                       24

     Houlihan Lokey's opinion does not address GZA's underlying business
decision to effect the Transaction. At the request of the Special Committee,
Houlihan Lokey solicited third party indications of interest in acquiring all or
part of GZA. Furthermore, at the request of the Special Committee, Houlihan
Lokey (i) participated in the negotiations with regard to the Transaction and
(ii) advised the Special Committee of the Board with respect to alternatives to
the Transaction.

     In connection with the preparation of its opinion, Houlihan Lokey made such
reviews, analyses and inquiries as they deemed necessary and appropriate under
the circumstances. Among other things, Houlihan Lokey:

          1. reviewed GZA's annual reports to stockholders and on Form 10-K for
     the five fiscal years ended February 29, 2000 and its quarterly report on
     Form 10-Q for the three months ended May 31, 2000, which the Company's
     management has identified as being the most current financial statements
     available;

          2. reviewed the Draft Agreement and Plan of Merger dated August 7,
     2000;

          3. met with certain members of the senior management of GZA to discuss
     the operations, financial condition, future prospects and projected
     operations and performance of GZA;

          4. visited certain facilities and business offices of GZA;

          5. reviewed forecasts and projections prepared by GZA's management
     with respect to GZA for the year ending February 28, 2001;

          6. reviewed the historical market prices and trading volume for GZA's
     publicly traded securities;

          7. reviewed certain other publicly available financial data for
     certain companies that Houlihan Lokey deemed comparable to GZA, and
     publicly available prices and premiums paid in other transactions that
     Houlihan Lokey considered similar to the Transaction;

          8. reviewed drafts of certain documents to be delivered at the closing
     of the Transaction;

          9. at the request of the Special Committee of GZA's Board of
     Directors, approached and held discussions with third parties to solicit
     indications of interest in the possible acquisition of GZA; and

          10. conducted such other studies, analyses and inquiries as Houlihan
     Lokey deemed appropriate.

     In assessing the financial fairness of the Transaction to the Public
Stockholders, Houlihan Lokey considered the trading history of GZA's public
securities and independently valued GZA using widely accepted valuation
methodologies.

  Assessment of GZA's Public Stock Price

     As part of its analysis, Houlihan Lokey analyzed the trading value of the
Common Stock over the past eighteen months on Nasdaq.

     Houlihan Lokey calculated the ratio of the GZA Common Stock's average daily
volume (over the most recent 90 days) to its float and total shares outstanding.
Houlihan Lokey then compared GZA's ratios to similar ratios of comparable
publicly traded companies.

     Based on these analyses, Houlihan Lokey observed that (i) GZA generally has
a smaller public float than the comparable public companies, (ii) GZA's common
equity securities generally do not trade as actively as the comparable public
companies, and (iii) GZA has less analyst coverage than most of the comparable
public companies.

</TABLE>

     Analysis of Control Premiums.  The analysis of control premiums involved
the application of control premium evidence from the comparable transaction
approach to GZA's unaffected stock price. The unaffected stock prices for GZA
are considered to be the periods prior to the announcement of the formation of
the Special Committee of the Board to review a proposal for acquisition by
certain members of management. These control premiums of 24% - 49% yielded an
implied value for the Common Stock of $6.22 to $6.50 per share.

VALUATION OF GZA

     As part of its analysis, Houlihan Lokey completed an independent valuation
of GZA using the market multiple and comparable transaction approaches in
addition to analyzing the recent trading history of the Company's Common Stock.

     As part of its analysis, Houlihan Lokey considered a number of GZA-specific
factors relevant to its valuation. Houlihan Lokey considered the value of (i)
GZA's excess cash, liquid assets and other non-operating assets, (ii) certain
potential contingent liabilities, and (iii) the dilutive impact of GZA's
outstanding stock options (collectively, the "Other Factors"). Based on this
analysis, the total additive impact of these Other Factors was in the range of
$1.57 to $2.23 per share.

     Market Multiple Approach.  The first approach, the market multiple
approach, involved the multiplication of revenue, earnings and asset measures by
appropriate risk-adjusted multiples. Multiples were determined through an
analysis of certain publicly traded companies, selected on the basis of
operational and economic similarity with the principal business operations of
GZA. Revenue, earnings, and asset multiples were calculated for the comparative
companies based upon daily trading prices. A comparative risk analysis between
GZA and these public companies formed the basis for the selection of appropriate
risk adjusted multiples for GZA. The risk analysis incorporated both
quantitative and qualitative risk factors, which relate to, among other things,
the nature of the industry in which GZA and the other comparative companies are
engaged.

     For purposes of this analysis, Houlihan Lokey selected nine publicly
traded, domestic companies involved in providing environmental engineering
services. These companies were CET Environmental Services, Ecology and
Environment, EA Engineering, Science and Technology, STV Group, IT Group, Tetra
Tech, TRC Companies, Versar and Roy F. Weston. It should be noted that no
company utilized in this analysis is identical to GZA.

     Houlihan Lokey reviewed trailing latest twelve month multiples of revenues,
earnings before interest, taxes, depreciation and amortization ("EBITDA") and
earnings before interest and taxes ("EBIT"), and projected EBITDA and EBIT for
the next fiscal year and multiples of assets for the comparable companies. The
multiples for the comparable companies are summarized below:

                  RANGE OF MULTIPLES FOR COMPARABLE COMPANIES

<TABLE>
<CAPTION>
                                            REVENUE    EBITDA    EBIT    ASSETS

High......................................   2.05       13.2     22.2     2.65

</TABLE>

                                       26
<PAGE>   29

     These valuation multiples and consideration of the Other Factors yielded an
implied value for the Common Stock of approximately $5.68 to $7.50 per share.

     Comparable Transaction Approach.  The second approach, the comparable
transaction approach, also involved multiples of revenue, cash flow and assets.
Multiples analyzed in this approach involved controlling interest transactions
for companies with operations similar in some manner to GZA's operations. For
purposes of this analysis, Houlihan Lokey analyzed nineteen private transactions
that occurred between 1996 and 2000.

     Based on the comparable transaction evidence, Houlihan Lokey observed
EBITDA multiples in the range of 4.6x to 12.0x and Revenue multiples in the
range of 0.26x to 1.00x. These valuation multiples and consideration of the
Other Factors yielded an implied value for the Common Stock of $6.81 to $7.13
per share.

     Separately, Houlihan Lokey examined the acquisition of Harding Lawson,
another environmental engineering and consulting firm acquired in June 2000.
This analysis also involved multiples of revenue, EBIT, EBITDA and assets. These
valuation multiples and consideration of the Other Factors yielded an implied
value for the Common Stock of $5.54 to $7.24 per share.

  Assessment of GZA's Strategic Alternatives to the Transaction

     In evaluating the fairness of the Transaction, from a financial point of
view, Houlihan Lokey considered the expected value to GZA's Public Stockholders
of completing the Transaction and certain alternatives to the Transaction.

     In the course of working for the Special Committee, Houlihan Lokey
considered the following strategic alternatives: (i) status quo; (ii) sale to a
strategic buyer; and (iii) sale to a financial buyer. The assessment of
strategic alternatives included an assessment of the valuation impact of the
Transaction relative to the alternatives considered by Houlihan Lokey. The
analysis did not quantify the valuation impact because, in the opinion of
Houlihan Lokey, it was not feasible to so quantify such impact due to the
significant number of non-quantifiable variables.

     Houlihan Lokey relied upon and assumed, without independent verification,
that the financial forecasts and projections provided to them, as adjusted based
on their discussions with management, were reasonably prepared and reflected the
best currently available estimates of the future financial results and condition
of GZA, and that there had been no material change in the assets, financial
condition, business or prospects of GZA since the date of the most recent
financial statements made available to them.

     Houlihan Lokey did not independently verify the accuracy and completeness
of the information supplied to them with respect to GZA and does not assume any
responsibility with respect to it. Houlihan Lokey has not made any independent
appraisal of any of the properties or assets of GZA. Houlihan Lokey's opinion
was necessarily based on business, economic, market and other conditions as they
existed and could be evaluated by them at the date of their letter.

     Houlihan Lokey's opinion is for the use and benefit of the Special
Committee of the Board of Directors and the Board of Directors of the Company in
its evaluation of the Transaction and should not be used by any other person
without the prior written consent of Houlihan Lokey.

     The opinion of Houlihan Lokey and its presentations to the Special
Committee and to GZA's Board constituted only one of a number of factors taken
into consideration by the Board in making its determination to approve the
Transaction. In addition, Houlihan Lokey's opinion does not constitute a
recommendation to the Special Committee of the Board of Directors, the Board of
Directors or any stockholder of the Company as to how to vote in connection with
the Transaction.

     Houlihan Lokey is a nationally recognized investment banking firm with
special expertise in, among other things, valuing businesses and securities and
rendering fairness opinions. Houlihan Lokey is continually engaged in the
valuation of businesses and securities in connection with mergers and
acquisitions, leveraged buyouts, private placements of debt and equity,
corporate reorganizations, employee stock ownership plans,
                                       27
<PAGE>   30

corporate and other purposes. The Special Committee selected Houlihan Lokey
because of its industry experience and expertise in mergers and acquisitions and
in performing valuation and fairness analyses. Houlihan Lokey does not
beneficially own nor has it ever beneficially owned any interest in GZA.

FEES AND EXPENSES

     Pursuant to an agreement dated March 6, 2000, Houlihan Lokey was retained
by the Special Committee to provide investment banking and financial advisory
services. GZA has agreed to pay Houlihan Lokey a fee of $175,000 (of which
$25,000 has already been paid) plus its reasonable out-of-pocket expenses
incurred in connection with the rendering of a fairness opinion. GZA has further
agreed to indemnify Houlihan Lokey against certain liabilities and expenses in
connection with the rendering of its services. Houlihan Lokey has in the past
provided financial services to GZA unrelated to the Transaction, for which
services Houlihan Lokey has received compensation.

PURPOSE AND STRUCTURE OF THE MERGER

     The purpose of the merger is to provide GZA stockholders cash for their
shares (other than excluded shares), to permit Futureco to acquire ownership of
GZA, to increase the percentage of GZA Common Stock owned indirectly by the
participating executives and participating employees through their equity
interest in Futureco, and to terminate the status of GZA as a company with
publicly traded equity. The Transaction has been structured as a cash merger in
order to provide the Public Stockholders of GZA with cash for all of their
shares and to provide a prompt and orderly transfer of ownership of GZA with
reduced transaction costs.

EFFECTS OF THE MERGER

     After the merger becomes effective, current GZA stockholders, other than
Futureco, will cease to have ownership interests in GZA or rights as GZA
stockholders. Therefore, the current stockholders of GZA, other than Futureco,
will not participate in any future earnings or losses and growth or decline of
GZA.

     As a result of the merger, GZA will be a privately-held corporation and
there will be no public market for its Common Stock. After the merger, the GZA
Common Stock will cease to be quoted on The Nasdaq Stock Market and price
quotations with respect to sales of shares of GZA Common Stock in the public
market will no longer be available. In addition, registration of the GZA Common
Stock under the Exchange Act will be terminated. This termination will make
certain provisions of the Exchange Act, such as the short-swing profit recovery
provisions of Section 16(b) and the requirement of furnishing a proxy or
information statement in connection with stockholders meetings, no longer
applicable to GZA. After the effective time of the merger, GZA will no longer be
required to file periodic reports with the Commission.

     When the merger becomes effective, the directors of the Merger Subsidiary
will become the directors of GZA, and the officers of the Merger Subsidiary will
become the officers of GZA. When the merger becomes effective, GZA's certificate
of incorporation will be amended to be the same as the certificate of
incorporation of the Merger Subsidiary was immediately before the effective time
of the merger. At the effective time of the merger, the bylaws of GZA will be
amended to be the same as the bylaws of the Merger Subsidiary were immediately
before the effective time of the merger.

     It is expected that following completion of the merger, the operations of
GZA will be conducted substantially as they are currently being conducted.
Neither GZA, the Futureco Parties, nor any of the participating executives has
any present plans or proposals that relate to or would result in an
extraordinary corporate transaction involving GZA's corporate structure,
business or management, such as a merger, reorganization, liquidation,
relocation of any operations, or sale or transfer of a material amount of
assets. However, GZA, the Futureco Parties and the participating executives will
continue to evaluate GZA's business and operations after the merger, and may
develop new plans and proposals that GZA, the Futureco Parties or the
participating executives consider to be in the best interests of GZA and its
private stockholders.

                                       28
<PAGE>   31

     The merger will add significant new long-term debt to GZA's balance sheet.
It is anticipated that approximately $15 million of third-part financing will
initially be required to finance the merger. GZA will become a wholly-owned
subsidiary of Futureco and on a consolidated basis stockholder equity will
change from approximately $25.8 million before the merger to approximately $4.2
million (without taking into account any loans that may be made by Futureco to
finance the acquisition of Futureco common stock by employees) after the merger.
After the merger, the present executive officers and directors of the Merger
Subsidiary will replace the present executive officers and directors of GZA.

     Immediately before the merger becomes effective, all GZA stock options will
become vested under the terms of the Merger Agreement and will thus be entitled
to participate in the exchange as shares of Common Stock. With the exception of
the excluded options, the option shares will be exchanged for a cash payment
equal to the excess of $6.40 per share over the aggregate exercise price of the
options, subject to any withholding for taxes. Options held by the participating
executives to purchase an aggregate of        shares of GZA Common Stock at
exercise prices ranging from $       to $       will be converted to options to
purchase an aggregate of        shares of Futureco Common Stock, at exercise
prices ranging from $       to $       per share. Additional options to purchase
an aggregate of        shares of GZA Common Stock held by other participating
employees may also be converted to options to purchase Futureco common stock.

RISK THAT THE MERGER WILL NOT BE COMPLETED

     Completion of the merger is subject to various conditions, including, but
not limited to, the following:

     - approval and adoption of the Merger Agreement and the transactions
       contemplated by the Merger Agreement by the stockholders of GZA;

     - securing required third party consents to the merger;

     - Futureco's securing the financing necessary to complete the merger and
       the transactions contemplated by the Merger Agreement on terms acceptable
       to Futureco; Futureco has advised GZA that the terms of the financing
       commitment already obtained (except for certain financial covenants that
       have not yet been negotiated) are acceptable to Futureco. See
       " -- Financing for the Merger;"

     - the representations and warranties made by the parties in the Merger
       Agreement must be true and correct in all material respects at the time
       the merger becomes effective;

     - the absence of any pending action or proceeding by any governmental
       authority, or by any other person or entity before any court or
       governmental authority, that has a reasonable likelihood of materially
       restraining, delaying or prohibiting the completion of the merger.

     As a result of the various conditions to the completion of the merger, we
cannot assure you that the merger will be completed even if the requisite
stockholder approval is obtained.

     It is expected that if GZA stockholders do not approve and adopt the Merger
Agreement and the transactions contemplated by the Merger Agreement, or if the
merger is not completed for any other reason, the current management of GZA,
under the direction of the Board of Directors, will continue to manage GZA as an
on-going business.

INTERESTS OF CERTAIN GZA DIRECTORS, OFFICERS AND STOCKHOLDERS IN THE MERGER

     In considering the recommendations of the Board of Directors, you should be
aware that members of GZA's management and the Board of Directors have interests
in the transaction that are or may be different from, or in addition to, your
interests as a GZA stockholder. The Board of Directors appointed the Special
Committee, consisting solely of directors who are not officers or employees of
GZA, and who have no financial interest in the proposed merger different from
GZA stockholders generally, to consider and negotiate the Merger Agreement and
to evaluate whether the merger is in the best interests of GZA's Public
Stockholders.

                                       29
<PAGE>   32

The Special Committee was aware of these differing interests and considered
them, among other matters, in approving the Merger Agreement and the
transactions contemplated by the Merger Agreement, and in recommending to the
Board of Directors and to GZA stockholders that the Merger Agreement and the
transactions contemplated by the Merger Agreement be approved and adopted.

     Executive Officers.  Under the terms of the Merger Agreement, upon
completion of the merger, the current GZA officers will cease to be officers of
GZA and will be replaced by the officers of Futureco. See "INFORMATION ABOUT
FUTURECO."

     Futureco will hold 100% of the GZA Common Stock after completion of the
merger, and the participating executives and participating employees will hold
Futureco common stock and options to purchase common stock of Futureco. The
opportunity to retain an indirect equity interest in GZA following completion of
the merger through their ownership of Futureco common stock gives the
participating executives and participating employees interests in connection
with the merger that are different from your interests as a GZA stockholder. See
"THE MERGER AGREEMENT -- Effect on Capital Stock."

     As a result of the merger, Futureco will not recognize gain or loss for
U.S. Federal income tax purposes on the Common Stock that it retains.

     Post-Merger Ownership of Futureco Common Stock.  We have been informed by
Futureco that the participating executives will hold the indicated number and
percent of shares of Futureco common stock outstanding immediately after
completion of the merger, on a fully diluted basis:

    estimate as to the number of shares which will be purchased by participating
    employees, and assumes the exercise of all options to purchase Futureco
    common stock expected to be outstanding immediately following the merger.

     Retention Agreement.  Andrew Pajak, GZA's President and Chief Executive
Officer, expects to leave GZA if the merger is consummated. In order to retain
his services in the meantime, GZA entered into a retention agreement with Mr.
Pajak on July 21, 2000. Under that agreement, if Mr. Pajak leaves after the
merger, under the circumstances set forth in the retention agreement, he will
receive a severance payment equal to his base salary and benefits for up to nine
months or until March 31, 2001, whichever is longer, plus a pro-rated part of an
amount equal to the average annual bonus paid to him during three fiscal years
preceding his leaving, plus all accrued vacation and deferred compensation. In
addition, GZA must provide outplacement services to him at a cost of up to
$50,000, and must assign to him certain ownership rights on the key man life
insurance policy that GZA currently maintains on his life, with a current
coverage of $750,000. GZA will also release Mr. Pajak from his existing
contractual obligations not to compete with GZA. The unvested part of restricted
stock awarded to Mr. Pajak under GZA's 1995 stock incentive plan and unvested
contributions to his 401(k) account will vest immediately in full.

  Employment Agreements.

     Indemnification of Directors and Officers, Directors' and Officers'
Insurance.  The Merger Agreement provides that GZA will indemnify and hold
harmless each present and former director and officer of GZA for acts and
omissions occurring before the merger becomes effective. The Merger Agreement
further provides that for a period of six years after the merger becomes
effective, GZA will maintain officers' and directors' liability insurance
covering the persons who, on the date of the Merger Agreement, were covered by
GZA's officers' and directors' liability insurance policies with respect to acts
and omissions occurring before the effective time of the merger. The persons
benefiting from the insurance provisions include all of GZA's current directors
and executive officers. See "THE MERGER AGREEMENT -- Indemnification."

     Common Stock.  As of the record date, GZA's directors and executive
officers held an aggregate of [  ] shares of Common Stock, and other employees
of GZA held an additional [  ] shares of GZA Common Stock.

     Treatment of Stock Options.  As of the record date, GZA's directors and
executive officers held options to purchase an aggregate of [  ] shares of
Common Stock. In connection with the merger, the holders of options whether or
not vested, other than excluded options held by participating employees, will
receive a cash payment from GZA equal to the excess of the $6.40 per share for
the shares subject to the options over the aggregate exercise price of the
options.

FINANCING FOR THE MERGER

     Futureco has received and accepted a commitment letter to finance the
merger from KeyBank National Association. The commitment is in the amount of
$19.5 million, $9.5 million of which is structured as a term loan facility and
$10 million of which is a revolving credit facility which can be borrowed,
repaid and reborrowed. It is expected that the entire term loan and
approximately $5.5 million of the revolver will be drawn down to finance the
acquisition of shares of GZA Common Stock. The borrowers of the loans will
initially be Futureco and the Merger Subsidiary. Upon the completion of the
merger, GZA will assume any liabilities of the Merger Subsidiary, including the
loans. The loans will be guaranteed by all of the wholly-owned subsidiaries of
GZA (and subsidiaries which would be wholly owned except for licensing
requirements in various jurisdictions), and will be secured by a first lien on
all of the assets of each of the borrowers and the guarantors.

     Interest on the revolver is payable monthly, with the principal amount of
the revolver due in three years, renewable at the option of the bank thereafter.
The term loan is payable in monthly payments of principal of $113,094 plus
interest and matures in seven years. At the option of Futureco, the loans will
bear interest at either rates based upon the London Interbank Offered Rate
("LIBOR") or the Wall Street Journal Prime Rate. Depending upon the ratio of
total funded debt to earnings of the borrowers before interest, taxes,
depreciation and amortization on a consolidated basis ("EBITDA"), the interest
rate on the revolver may range from LIBOR plus one hundred and fifty basis
points to LIBOR plus two hundred and fifty basis points or from Prime to Prime
plus fifty basis points with a commitment fee payable on the unused portion of
the revolver. The term loan may bear interest, depending upon the ratio of total
funded debt to EBITDA, of from LIBOR plus one hundred seventy five basis points
to LIBOR plus two hundred seventy five basis points or from Prime to Prime plus
fifty basis points.

     The commitment is subject to, among other things, the bank's receipt and
complete satisfaction with financial statement projections in a fiscal quarterly
format for the period commencing August 31, 2000 and ending February 28, 2003
and with an environmental issues checklist to be completed by borrowers and the
execution by borrowers and the guarantors of loan and security documents with
such loan covenants as are satisfactory to the bank. The borrowers have the
right to terminate the commitment if the financial covenants imposed by the bank
upon a review of the financial projections are not acceptable to the borrowers.

ACCOUNTING TREATMENT OF THE MERGER

     We intend to account for the merger and related transactions primarily
under the purchase method of accounting for business combinations. Under this
method of accounting and in accordance with the provisions

                                       31
<PAGE>   34

of Issue No. 88-16 promulgated by the Emerging Issues Task Force of the
Financial Accounting Standards Board, the cost to acquire GZA, including
transaction costs, will be allocated to its underlying net assets to proportion
to their respective fair values. GZA shares contributed to Futureco by GZA
employees in exchange for Futureco shares in contemplation of the acquisition.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES TO STOCKHOLDERS

     The following is a summary of the material U.S. Federal income tax
consequences of the merger to holders of Common Stock (including holders
exercising appraisal rights) who receive cash in the merger. This summary is
based on laws, regulations, rulings and decisions now in effect, all of which
are subject to change, possibly with retroactive effect. This summary does not
address all of the U.S. Federal income tax consequences that may be applicable
to a particular holder of Common Stock or to holders who are subject to special
treatment under U.S. Federal income tax law (including, for example, banks,
insurance companies, tax-exempt investors, S corporations, dealers in
securities, non-U.S. persons, holders who hold their Common Stock as part of a
hedge, straddle or conversion transaction, and holders who acquired Common Stock
through the exercise of employee stock options or other compensation
arrangements). Moreover, this summary does not deal with the consequences to
employees of GZA to the extent that they exchange their Common Stock or options
to purchase GZA Common Stock for options to purchase common stock of Futureco.
In addition, this summary does not address the tax consequences of the merger
under applicable state, local or foreign laws. YOU SHOULD CONSULT YOUR OWN TAX
ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO YOU OF THE MERGER, INCLUDING
THE APPLICATION OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.

     The receipt of cash by holders of Common Stock in the merger or upon
exercise of dissenters' appraisal rights will be a taxable transaction for U.S.
Federal income tax purposes. A holder of Common Stock generally will recognize
gain or loss in an amount equal to the difference between the merger
consideration received by the holder and the holder's adjusted tax basis in the
Common Stock. That gain or loss generally will be capital gain or loss if the
Common Stock is held as a capital asset at the effective time of the merger. Any
capital gain or loss generally will be long-term capital gain or loss if the
Common Stock has been held by the holder for more than one year. If the Common
Stock has been held by the holder for less than one year, any gain or loss will
generally be taxed as a short-term capital gain or loss.

DISSENTERS' RIGHTS OF APPRAISAL

     Under Section 262 of the Delaware General Corporation Law, which we refer
to as the "DGCL," any holder of Common Stock who does not wish to accept $6.40
per share in cash for the holder's shares of Common Stock may dissent from the
merger and elect to have the fair value of the holder's shares of Common Stock
(exclusive of any element of value arising from the accomplishment or
expectation of the merger) judicially determined and paid to the holder in cash,
together with a fair rate of interest, if any, provided that the holder complies
with the provisions of Section 262.

     The following discussion is not a complete statement of the law pertaining
to appraisal rights under the DGCL, and is qualified in its entirety by the full
text of Section 262, which is provided in its entirety as Appendix C to this
Proxy Statement. All references in Section 262 and in this summary to a
"stockholder" are to the record holder of the shares of Common Stock as to which
appraisal rights are asserted. A PERSON HAVING A BENEFICIAL INTEREST IN SHARES
OF COMMON STOCK HELD OF RECORD IN THE NAME OF ANOTHER PERSON, SUCH AS A BROKER
OR NOMINEE, MUST ACT PROMPTLY TO CAUSE THE RECORD HOLDER TO FOLLOW PROPERLY THE
STEPS SUMMARIZED BELOW AND IN A TIMELY MANNER TO PERFECT APPRAISAL RIGHTS.

     Under Section 262, where a proposed merger is to be submitted for approval
and adoption at a meeting of stockholders, as in the case of the Special
Meeting, the corporation, not less than 20 days before the meeting, must notify
each of its stockholders entitled to appraisal rights that appraisal rights are
available and include in that notice a copy of Section 262. This Proxy Statement
constitutes that notice to the holders of Common
                                       32
<PAGE>   35

Stock and the applicable statutory provisions of the DGCL are attached to this
Proxy Statement as Appendix C. Any stockholder who wishes to exercise appraisal
rights or who wishes to preserve the right to do so should review carefully the
following discussion and Appendix C to this Proxy Statement. FAILURE TO COMPLY
WITH THE PROCEDURES SPECIFIED IN SECTION 262 TIMELY AND PROPERLY WILL RESULT IN
THE LOSS OF APPRAISAL RIGHTS. Moreover, because of the complexity of the
procedures for exercising the right to seek appraisal of the Common Stock, GZA
believes that stockholders who consider exercising appraisal rights should seek
the advice of counsel.

     Any holder of Common Stock wishing to exercise the right to demand
appraisal under Section 262 of the DGCL must satisfy each of the following
conditions:

     - as more fully described below, the holder must deliver to GZA a written
       demand for appraisal of the holder's shares before the vote on the Merger
       Agreement at the Special Meeting, which demand will be sufficient if it
       reasonably informs GZA of the identity of the holder and that the holder
       intends to demand the appraisal of the holder's shares;

     - the holder must not vote the holder's shares of Common Stock in favor of
       the Merger Agreement; a proxy which does not contain voting instructions
       will, unless revoked, be voted in favor of the Merger Agreement;
       therefore, a stockholder who votes by proxy and who wishes to exercise
       appraisal rights must vote against the Merger Agreement or abstain from
       voting on the Merger Agreement; and

     - the holder must continuously hold the shares from the date of making the
       demand through the effective time of the merger; a stockholder who is the
       record holder of shares of Common Stock on the date the written demand
       for appraisal is made but who thereafter transfers those shares before
       the effective time of the merger will lose any right to appraisal in
       respect of those shares.

     Neither voting (in person or by proxy) against, abstaining from voting on
or failing to vote on the proposal to approve the Merger Agreement and the
transactions contemplated by the Merger Agreement will constitute a written
demand for appraisal within the meaning of Section 262. The written demand for
appraisal must be in addition to and separate from any proxy or vote.

     Only a holder of record of shares of Common Stock issued and outstanding
immediately before the effective time of the merger is entitled to assert
appraisal rights for the shares of Common Stock registered in that holder's
name. A demand for appraisal should be executed by or on behalf of the
stockholder of record, fully and correctly, as the stockholder's name appears on
the stock certificates, should specify the stockholder's name and mailing
address, the number of shares of Common Stock owned and that the stockholder
intends to demand appraisal of the stockholder's Common Stock. If the shares are
owned of record in a fiduciary capacity, such as by a trustee, guardian or
custodian, execution of the demand should be made in that capacity. If the
shares are owned of record by more than one person, as in a joint tenancy or
tenancy in common, the demand should be executed by or on behalf of all owners.
An authorized agent, including one or more joint owners, may execute a demand
for appraisal on behalf of a stockholder; however, the agent must identify the
record owner or owners and expressly disclose the fact that, in executing the
demand, the agent is acting as agent for the owner or owners. A record holder
such as a broker who holds shares as nominee for several beneficial owners may
exercise appraisal rights with respect to the shares held for one or more
beneficial owners while not exercising appraisal rights with respect to the
shares held for one or more beneficial owners; in that case, the written demand
should set forth the number of shares as to which appraisal is sought, and where
no number of shares is expressly mentioned the demand will be presumed to cover
all shares held in the name of the record owner. STOCKHOLDERS WHO HOLD THEIR
SHARES IN BROKERAGE ACCOUNTS OR OTHER NOMINEE FORMS AND WHO WISH TO EXERCISE
APPRAISAL RIGHTS ARE URGED TO CONSULT WITH THEIR BROKERS TO DETERMINE
APPROPRIATE PROCEDURES FOR THE MAKING OF A DEMAND FOR APPRAISAL BY THE NOMINEE.

                                       33
<PAGE>   36

     A stockholder who elects to exercise appraisal rights under Section 262
should mail or deliver a written demand to: GZA GeoEnvironmental Technologies,
Inc., 320 Needham Street, Newton Upper Falls, Massachusetts 02464, Attn: Robert
W. Sweet, Jr., Secretary.

     Within ten days after the effective time of the merger, GZA must send a
notice as to the effectiveness of the merger to each former stockholder of GZA
who has made a written demand for appraisal in accordance with Section 262 and
who has not voted to approve and adopt the Merger Agreement and the transactions
contemplated by the Merger Agreement. Within 120 days after the effective time
of the Merger, but not thereafter, either GZA or any dissenting stockholder who
has complied with the requirements of Section 262 may file a petition in the
Delaware Court of Chancery demanding a determination of the value of the shares
of Common Stock held by all dissenting stockholders. GZA is under no obligation
to and has no present intent to file a petition for appraisal, and stockholders
seeking to exercise appraisal rights should not assume that GZA will file a
petition or that GZA will initiate any negotiations with respect to the fair
value of the shares. Accordingly, stockholders who desire to have their shares
appraised should initiate any petitions necessary for the perfection of their
appraisal rights within the time periods and in the manner prescribed in Section
262. Inasmuch as GZA has no obligation to file a petition, the failure of a
stockholder to do so within the period specified could nullify the stockholder's
previous written demand for appraisal.

     Under the Merger Agreement, GZA has agreed to give Futureco prompt written
notice of any demands for appraisal received by GZA. Futureco has the right to
participate in and approve all negotiations and proceedings with respect to
demands for appraisal under the DGCL. GZA will not, except with the prior
written consent of Futureco, make any payment with respect to any demands for
appraisal, or offer to settle, or settle, any demands. If the holders of more
than 5% of the outstanding stock demand appraisal, Futureco will have the right
not to complete the merger.

     Within 120 days after the effective time of the merger, any stockholder who
has complied with the provisions of Section 262 to that point in time will be
entitled to receive from GZA, upon written request, a statement setting forth
the aggregate number of shares not voted in favor of the Merger Agreement and
with respect to which demands for appraisal have been received and the aggregate
number of holders of shares. GZA must mail that statement to the stockholder
within 10 days of receipt of the request or within 10 days after expiration of
the period for delivery of demands for appraisals under Section 262, whichever
is later.

     A stockholder timely filing a petition for appraisal with the Delaware
Court of Chancery must deliver a copy to GZA, which will then be obligated
within 20 days to provide the Delaware Court of Chancery with a duly verified
list containing the names and addresses of all stockholders who have demanded
appraisal of their shares. After notice to those stockholders, the Delaware
Court of Chancery is empowered to conduct a hearing on the petition to determine
which stockholders are entitled to appraisal rights. The Delaware Court of
Chancery may require stockholders who have demanded an appraisal for their
shares and who hold stock represented by certificates to submit their
certificates to the Register in Chancery for notation thereon of the pendency of
the appraisal proceedings, and if any stockholder fails to comply with the
requirement, the Delaware Court of Chancery may dismiss the proceedings as to
that stockholder.

     After determining the stockholders entitled to an appraisal, the Delaware
Court of Chancery will appraise the "fair value" of their shares, exclusive of
any element of value arising from the accomplishment or expectation of the
merger, together with a fair rate of interest, if any, to be paid upon the
amount determined to be the fair value. The costs of the action may be
determined by the Delaware Court of Chancery and taxed upon the parties as the
Delaware Court of Chancery deems equitable. Upon application of a dissenting
stockholder, the Delaware Court of Chancery may also order that all or a portion
of the expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorneys' fees and the
fees and expenses of experts, be charged pro rata against the value of all of
the shares entitled to appraisal. STOCKHOLDERS CONSIDERING SEEKING APPRAISAL
SHOULD BE AWARE THAT THE FAIR VALUE OF THEIR SHARES AS DETERMINED UNDER SECTION
262 COULD BE MORE THAN, THE SAME AS OR LESS THAN THE $6.40 PER SHARE THEY WOULD
RECEIVE UNDER THE MERGER AGREEMENT IF THEY DID NOT SEEK APPRAISAL OF THEIR
SHARES. STOCKHOLDERS SHOULD ALSO BE AWARE THAT INVESTMENT BANKING OPINIONS ARE
NOT OPINIONS AS TO FAIR VALUE UNDER SECTION 262.

                                       34
<PAGE>   37

     In determining fair value and, if applicable, a fair rate of interest, the
Delaware Court of Chancery is to take into account all relevant factors. In
Weinberger v. UOP, Inc., the Delaware Supreme Court discussed the factors that
could be considered in determining fair value in an appraisal proceeding,
stating that "proof of value by any techniques or methods that are generally
considered acceptable in the financial community and otherwise admissible in
court" should be considered, and that "fair price obviously requires
consideration of all relevant factors involving the value of a company." The
Delaware Supreme Court stated that, in making this determination of fair value,
the court must consider market value, asset value, dividends, earnings
prospects, the nature of the enterprise and any other facts that could be
ascertained as of the date of the merger that throw any light on future
prospects of the merged corporation. In Weinberger, the Delaware Supreme Court
stated that "elements of future value, including the nature of the enterprise,
which are known or susceptible of proof as of the date of the merger and not the
product of speculation, may be considered." Section 262 provides that fair value
is to be "exclusive of any element of value arising from the accomplishment or
expectation of the merger."

     Any stockholder who has duly demanded an appraisal in compliance with
Section 262 will not, after the effective time of the merger, be entitled to
vote the shares subject to that demand for any purpose or be entitled to the
payment of dividends or other distributions on those shares (except dividends or
other distributions payable to holders of record of shares as of a record date
before the effective time of the merger).

     Any stockholder may withdraw its demand for appraisal and accept $6.40 per
share by delivering to GZA a written withdrawal of the stockholder's demand for
appraisal, except that (1) any attempt to withdraw made more than 60 days after
the effective time of the merger will require written approval of GZA and (2) no
appraisal proceeding in the Delaware Court of Chancery will be dismissed as to
any stockholder without the approval of the Delaware Court of Chancery, and the
approval may be conditioned upon such terms as the Delaware Court of Chancery
deems just. If GZA does not approve a stockholder's request to withdraw a demand
for appraisal when that approval is required or if the Delaware Court of
Chancery does not approve the dismissal of an appraisal proceeding, the
stockholder would be entitled to receive only the appraised value determined in
any appraisal proceeding, which value could be more than, the same or less than
$6.40 per share.

     FAILURE TO COMPLY STRICTLY WITH ALL OF THE PROCEDURES SET FORTH IN SECTION
262 OF THE DGCL MAY RESULT IN THE LOSS OF A STOCKHOLDER'S STATUTORY APPRAISAL
RIGHTS. CONSEQUENTLY, ANY STOCKHOLDER WISHING TO EXERCISE APPRAISAL RIGHTS IS
URGED TO CONSULT LEGAL COUNSEL BEFORE ATTEMPTING TO EXERCISE APPRAISAL RIGHTS.

                              THE MERGER AGREEMENT

     The description of the Merger Agreement contained in this Proxy Statement
describes the material terms of the Merger Agreement. The complete terms of the
Merger Agreement may be found in Appendix A to this Proxy Statement and are
incorporated herein by reference. Stockholders are urged to read the entire
Merger Agreement.

THE MERGER

     The Merger Agreement provides that, subject to conditions summarized below,
the Merger Subsidiary, a wholly owned subsidiary of Futureco, will merge with
and into GZA. Following completion of the merger, the Merger Subsidiary will
cease to exist as a separate entity, and GZA will continue as the surviving
corporation (which we will sometimes refer to as the "surviving corporation").

CLOSING OF THE MERGER

     Subject to the terms and conditions of the Merger Agreement, the
consummation of the merger is expected to take place as soon as practicable, but
in no event later than three business days, after the approval and adoption of
the Merger Agreement and the transactions contemplated by the Merger Agreement
by our stockholders at the Special Meeting and the satisfaction or waiver of the
other conditions to the merger contained in the Merger Agreement, unless another
date is agreed to in writing by the parties. This date of consummation is
referred to as the "Closing Date." We cannot assure you that all conditions to
the merger contained in the Merger Agreement will be satisfied or waived. See
"-- Closing Conditions."

EFFECTIVE TIME OF THE MERGER

     The merger will become effective when we file a Certificate of Merger,
together with any required related documents, with the Secretary of State of the
State of Delaware in accordance with DGCL. We refer to this time as the
"effective time." The filing will be made on the Closing Date.

DIRECTORS, OFFICERS AND GOVERNING DOCUMENTS

     From and after the effective time of the merger, the directors and officers
of the Merger Subsidiary will become the directors and officers, respectively,
of the surviving corporation, until successors are duly elected or appointed and
qualified. At the effective time of the merger, GZA's certificate of
incorporation will be amended to be the same as the certificate of incorporation
of the Merger Subsidiary was immediately before the effective time of the
merger. At the effective time of the merger, the bylaws of GZA will be amended
to be the same as the bylaws of the Merger Subsidiary were immediately before
the effective time of the merger.

EFFECT OF THE MERGER

     At the effective time of the merger, all the property rights, privileges,
powers and franchises of GZA and the Merger Subsidiary will vest in the
surviving corporation, as will all debts, liabilities and duties of GZA and the
Merger Subsidiary.

EFFECT ON CAPITAL STOCK

     At the effective time of the merger, by virtue of the merger, each issued
and outstanding share of the Merger Subsidiary common stock will be converted
into and become one fully paid and nonassessable share of $.01 par value, common
stock in the surviving corporation.

     At the effective time of the merger, by virtue of the merger, each share of
GZA Common Stock outstanding immediately prior to the effective time of the
merger will be canceled and automatically converted into the right to receive
$6.40 in cash without interest and less any required tax withholding, with the
following exceptions:

     - shares owned by Futureco at the effective time and listed on a schedule
       to be delivered to GZA by Futureco at least one day before the Closing
       Date, will be excluded shares and thus will continue to remain issued and
       outstanding;

     - options outstanding at the effective time to purchase GZA Common Stock
       granted pursuant to any GZA stock option plan, other than excluded
       options, will be exercised as of the effective time and the option shares
       will be considered issued and outstanding immediately before the
       effective time, and thus will participate in the exchange. However, the
       holders of these options must deliver duly executed stock option exercise
       agreements in a form specified by the Merger Agreement, at least one
       business day prior to the Closing Date, and payment for option shares
       will be reduced by the exercise price with respect to the option shares.
       Stock options not exercised prior to the effective time will be cancelled
       at the effective time. Excluded options listed on the excluded securities
       schedule will be exchanged for Futureco options at a specific rate.

                                       36
<PAGE>   39

     - shares held by GZA in its treasury immediately before the effective time
       of the merger will be canceled and retired without any payment thereon;
       and

     - shares held by dissenting stockholders will instead be subject to
       appraisal in accordance with DGCL. Dissenters are those who have neither
       voted in favor of the Merger nor consented to it in writing, and who have
       duly demanded appraisal for their shares under DGCL. Dissenters have the
       right to receive payment from the surviving corporation for the fair
       value of the shares they held immediately prior to the effective time,
       unless they do not perfect or they lose their appraisal rights, in which
       case their shares will be treated as if they were converted into the
       right to receive $6.40 in cash as of the effective time, without
       interest.

CERTIFICATES AND OWNERSHIP RIGHTS

     No later than one business day after the effective time, the surviving
corporation will mail to all stockholders and optionholders eligible to
participate, letters and instructions about surrendering stock certificates for
payment of the consideration discussed above (which we sometimes will refer to
as "Merger Consideration"). Within one business day of the surrender of those
certificates, with duly executed letters of transmittal, a paying agent, chosen
by Futureco and reasonably acceptable to GZA, will pay the share and option
holders the appropriate merger consideration per share multiplied by the number
of their participating shares. In exchange, their certificates will be canceled.
Until the surrender and exchange, each certificate will represent only the right
to be so exchanged without interest. If someone other than the person in whose
name the certificate is registered wants to exchange and surrender the
certificate, the certificate must be properly endorsed or in proper form for
transfer, plus the person requesting the exchange must pay the paying agent any
transfer or other taxes required because of such payment, unless that person
establishes to the paying agent that the taxes were paid or are inapplicable.

     YOU SHOULD NOT FORWARD SHARE CERTIFICATES WITH THE ENCLOSED PROXY CARD. YOU
SHOULD SURRENDER CERTIFICATES REPRESENTING SHARES OF COMMON STOCK ONLY AFTER
RECEIVING INSTRUCTIONS FROM THE PAYING AGENT.

     Promptly before the effective time, Futureco will deposit with the paying
agent funds equal to the aggregate amount of consideration to which the
stockholders and option holders are entitled at the effective time. This merger
consideration will be invested by the paying agent, as directed by Futureco and
GZA before the Closing Date from a limited set of investment choices laid out in
the Merger Agreement.

     One year after the effective time, the paying agent's duties will end and
the paying agent will deliver the cash and documents relating to the merger
consideration fund that were in its possession to the surviving corporation.
From then on, certificates may be surrendered to the surviving corporation for
exchange, without interest, subject to applicable abandoned property, escheat
and other similar laws. Neither Futureco, the Merger Subsidiary, nor the
surviving corporation will be liable to any holder of GZA Common Stock for any
merger consideration delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

     The paying agent or surviving corporation may deduct from the merger
consideration amount otherwise payable to share and option holders, the amounts
required to be withheld and deducted for tax purposes, and with respect to
option shares, the exercise price liability.

     The exchange of the GZA Common Stock shares and option shares for merger
consideration will fully satisfy all rights pertaining to those shares eligible
to participate in the exchange. There will be no further registration of
transfers of those participating shares on the records of the surviving
corporation.

     If a certificate for participating shares was lost, stolen or destroyed,
the paying agent will deliver the exchange amount upon receipt of an affidavit
attesting to what happened to the certificate, provided, however, that the
paying agent may at his discretion require the owner of the certificate to
deliver a reasonable bond as indemnity against claims with respect to the
certificate.

     Futureco, the Merger Subsidiary and GZA will all take reasonable and lawful
actions to carry out the merger in accordance with the Merger Agreement as
promptly as possible.

GZA COVENANTS

     We agreed in the Merger Agreement that prior to the effective time, except
with the prior written consent of Futureco, neither GZA nor any of our officers
or agents will solicit or seek to facilitate other merger or acquisition
proposals. We have agreed that if we receive any other acquisition proposals
prior to the effective time, we will notify Futureco immediately, and give
Futureco reasonable time to respond. We may not enter into a definitive
agreement with respect to another acquisition proposal during the term of the
Merger Agreement. However, our board or its Special Committee, as applicable,
may:

     - continue discussing and negotiating acquisition proposals with any party
       initially contacted by us or on our behalf before the execution of the
       Merger Agreement if the Special Committee in good faith reasonably
       believes that the negotiation could lead to a superior acquisition
       proposal;

     - enter into discussions with a person or entity that makes an unsolicited
       acquisition proposal, if and to the extent that the special committee
       determines in good faith that the proposal could lead to a superior
       acquisition proposal, and if and to the extent that failure to do so
       could constitute a breach of the fiduciary duties of the directors of GZA
       to GZA stockholders;

                                       40
<PAGE>   43

     - approve and recommend a superior acquisition proposal, and modify or
       withdraw its approval of the Merger Agreement, subject to the
       reimbursement of certain expenses incurred by Futureco in connection with
       the proposed merger, as explained in "THE MERGER
       AGREEMENT -- Termination, Amendment and Waiver."

     By a "superior acquisition proposal" we mean a bona fide acquisition
proposal made by a third party that the Special Committee determines in good
faith, after consultation with its financial advisor, could be more favorable to
GZA stockholders from a financial point of view than the one set forth in the
Merger Agreement, and one that is capable of being consummated within a
reasonable period of time.

     In the Merger Agreement, we agreed that before completion of the merger,
except as contemplated by the Merger Agreement and disclosure schedules, or
except with the prior written consent of Futureco, to conduct business only in
the usual, regular and ordinary course of business and consistent with past
practice and to use commercially reasonable efforts to maintain our business
organization, goodwill, and relationships with employees, customers, suppliers
and others with whom we do business. In addition, we agreed that subject to the
same conditions we will:

     - confer on a regular basis with one or more representatives of Futureco to
       report material operational matters and proposals to engage in other
       material transactions;

     - promptly notify Futureco of any material emergency or change in
       condition, properties, assets, liabilities, or course of operations, or
       of any material complaints, investigations, or hearings;

     - promptly deliver to Futureco SEC filings made after the date of the
       Merger Agreement;

     - maintain our books and records in accordance with generally accepted
       accounting principles and SEC requirements;

     - duly and timely make all required filings with governmental authorities,
       subject to permitted extensions of which Futureco receives notice;

     - not make or rescind any express or deemed election relative to taxes,
       except as required by law;

     - not amend our Certificate of Incorporation, bylaws, or any of our other
       organizational documents;

     - except for distributions made by our subsidiaries or except as
       contemplated by the Merger Agreement or GZA's existing employee stock
       purchase plan, not authorize or make distributions, repurchases or
       redemptions with respect to capital stock, options, warrants, or other
       GZA securities;

     - not dispose of any material part of our assets outside of the ordinary
       course of business consistent with past practice;

     - not make loans or advances, except to existing subsidiaries and as
       advances to employees in the ordinary course of business consistent with
       past practice for travel and business expenses;

     - not discharge or satisfy material claims, liabilities or obligations
       beyond what would be done in the ordinary course of business consistent
       with past practice, or as reflected in the financial statements provided
       to Futureco in connection with the Merger Agreement;

     - not enter into commitments that may result in payments in excess of
       $100,000;

     - not make material changes in employment and compensation arrangements or
       benefit plans with officers, directors, and employees; nor enter into new
       employment arrangements with anyone not currently employed by us,
       providing compensation in excess of $75,000 a year; except in the
       ordinary course of business consistent with past practice in timing and
       amount;

     - not settle any stockholder derivative or class action claims arising out
       of the Merger Agreement, without prior written approval of Futureco;

                                       41
<PAGE>   44

     - not reduce our ownership in any of our subsidiaries;

     - not change the rights under any agreements with our affiliates, officers,
       directors, and employees;

     - not directly or indirectly merge with or acquire beneficial ownership of
       a majority interest in any person or entity;

     - not enter into new commitments relating to our securities;

     - not incur new indebtedness beyond the financing of ordinary course of
       trade payables or existing credit facilities in the ordinary course of
       business;

     - not make any non-customary payments outside the ordinary course of
       business, beyond what is contemplated in the Merger Agreement;

     - not modify any agreements under which we have material rights; and

     - not agree to take any of the above-listed actions.

PREPARATION OF PROXY STATEMENT; STOCKHOLDER MEETING

     We agreed that we would promptly prepare the Schedule 13E-3 statement that
is required to be filed with the Commission and the proxy statement required to
be distributed to our stockholders in connection with the merger, and include in
the proxy statement an updated fairness opinion and recommendation of our Board
in favor of the approval of the Merger Agreement. However, the board may fail to
make or modify its recommendation if it decides to recommend a superior
acquisition proposal instead. We have agreed to use our best efforts to obtain
and furnish the information required to be included in the proxy statement and
Schedule 13E-3, and after consultation with Futureco, respond promptly to
Commission comments. Futureco and the Merger Subsidiary have agreed to cooperate
in the preparation of all of these filings. We also agreed to use reasonable
best efforts to mail the proxy statement to our stockholders as promptly as
practicable. All of these filings with the Commission and the related mailings
to our stockholders are subject to the prior review and approval of Futureco,
which it has agreed will not be unreasonably withheld.

     We agreed that subject to our receipt of a written fairness opinion from
Houlihan Lokey as of the date of the proxy mailing that the merger consideration
for stockholders is financially fair to them, we will, as promptly as
practicable duly call and hold our stockholders meeting for the purpose of
approving the Merger Agreement and its contemplated transactions.

ACCESS TO INFORMATION; CONFIDENTIALITY

     Subject to confidentiality agreements with third parties, we have agreed to
allow Futureco and the Merger Subsidiary, their officers, employees,
accountants, counsel, financial advisors and other representatives, reasonable
access during normal business hours before the effective time to all of our
properties, books, contracts, commitments, personnel and records. We further
agreed to furnish promptly to the other parties our filings with the Commission
and other information that they reasonably request. Each party will use
commercially reasonable efforts to hold nonpublic information in confidence in
accordance with the Confidentiality Agreement between GZA and Futureco dated
March 31, 2000. We have not agreed, however, to furnish Futureco or the Merger
Subsidiary with information related to meetings or activities of our Special
Committee or to potential transactions with third parties beyond what is
provided for in the Merger Agreement.

BEST EFFORTS; NOTIFICATION

     GZA and Futureco have agreed, subject to the terms of the Merger Agreement,
to use reasonable best efforts to cooperate in determining what filings need to
be made with, and authorizations received from,

                                       42
<PAGE>   45

governmental authorities in connection with the Merger Agreement; and then in
making those filings and obtaining those authorizations in a timely manner. In
addition, GZA and Futureco have agreed to use reasonable best efforts to
cooperate in obtaining necessary consents from third parties and in otherwise
appropriately consummating the transactions contemplated in the Merger
Agreement.

     GZA and Futureco have also agreed to promptly notify each other if any of
the representations or warranties that they made become untrue or inaccurate in
a material respect, or if they fail to materially satisfy any of the covenants
or conditions in the Merger Agreement.

COSTS OF TRANSACTION

     If the merger is not consummated, Futureco and GZA have agreed to pay their
own costs relating to the merger and the Merger Agreement, except as indicated
in the section on "-- Termination, Amendment and Waiver."

PUBLIC ANNOUNCEMENTS

     GZA, Futureco, and the Merger Subsidiary have agreed not to issue public
comments and statements with respect to the merger transactions without first
consulting each other, except as required by law or as agreed to in the Merger
Agreement.

TAXES

     We have agreed to let Futureco, at its own expense, review and comment on
our tax returns for the tax year ending on February 29, 2000.

RESIGNATIONS

     GZA directors will resign from their positions if so requested by Futureco
on the Closing Date, effective as of the effective time.

INDEMNIFICATION

     From and after the effective time, the surviving corporation will
exculpate, indemnify, and advance expenses for those who were officers and
directors of GZA before the effective time at least to the same extent provided
by GZA in its Certificate of Incorporation, bylaws and existing contractual
agreements in existence at the time the Merger Agreement was executed. These
protections will cover their actions on or prior to the effective time,
including transactions contemplated by the Merger Agreement. The surviving
corporation will obtain and maintain "tail" directors and officers liability
insurance for six years after the effective date, with coverage at least as
favorable as those in the indemnification agreements referred to above in this
paragraph.

     The surviving corporation or any of its respective successors or assignees
will pay all costs that may be incurred by any of these indemnified parties in
successfully enforcing the indemnity obligations of Futureco or the surviving
corporation under this section. This section will survive the merger, along with
the indemnified parties' other rights.

NO FURTHER STOCK AGREEMENTS

                                   DIVIDENDS

     GZA has never declared or paid any dividends with respect to its Common
Stock. Any determination to pay dividends in the future will be at the
discretion of the Board of Directors and will be dependent upon GZA's results of
operations, financial condition, capital expenditures, working capital
requirements, any contractual restrictions and other factors deemed relevant by
GZA's Board of Directors. GZA does not

                                       46
<PAGE>   49

anticipate that any cash dividends will be paid on its Common Stock in the
foreseeable future if, for any reason, the merger is not completed.

                       COMMON STOCK PURCHASE INFORMATION

     During the sixty days preceding the date of this Proxy Statement, certain
of the participating executives acquired shares of GZA Common Stock as follows:
each of Messrs. Celi, Hadge, and Hehir received a restricted stock award of
1,000 shares in September 2000. Each of Messrs. Celi, Hadge, and Hehir also
received at that time an incentive stock option to purchase 4,000 shares at an
exercise price of $       per share.

     GZA did not purchase any GZA Common Stock in 2000, 1999 or 1998, except as
follows. On July 14, 1997, the Board of Directors authorized the repurchase of
up to 250,000 shares of GZA stock from time to time at prevailing market rates.
The shares repurchased were to be used primarily for issuance under the
Company's 401(k) Plan, Employee Stock Purchase Plan, Stock Incentive Plan and
other equity incentive programs and, where necessary, for other appropriate
corporate purposes. The process was managed by the Chief Executive Officer, the
Chief Financial Officer and the Chairman of the Board's Audit Committee
according to guidelines established by the Board with progress periodically
reported to the Board. The principal reasons to implement this repurchase
program were to increase long-term stockholder value by reducing the number of
outstanding shares of Common Stock included in the Company's earnings per share,
to offset the dilutive effect of shares issued pursuant to the Company's 401(k)
Plan, Employee Stock Purchase Plan, and stock option plans; to provide liquidity
to existing stockholders that had been lacking as a result of the thin trading
volume in the Company's stock; and to improve employee morale. The directors
agreed that, at the then current market prices, the Company's stock was a good
investment and represented a more efficient use of the Company's cash than a
number of available investments. An August 6, 1997 press release announced the
Company's intent to initiate this stock buy-back program. On December 17, 1997,
the Board voted to increase the buy-back to a total of 500,000 shares under
previously established guidelines. Through August 1998, 500,000 shares of GZA
stock were repurchased at an average price of $4.91 share. In September 1998,
the Board decided to suspend further buy-back efforts in order to consider other
uses of the Company's cash.

                      PROPOSAL TWO: ELECTION OF DIRECTORS

     We have a classified Board of Directors consisting of Class I, Class II and
Class III directors who serve three-year terms, with the term of one of the
three classes expiring each year, concurrently with the Company's Annual
Meeting. Our by-laws specify that the number of directors constituting each
class shall be as nearly equal as possible. However, if the merger is approved
and consummated, the directors of the Merger Subsidiary, William R. Beloff,
William E. Hadge, Joseph P. Hehir, M. Joseph Celi and Lawrence Feldman will
become the directors of GZA, and the bylaws of the Merger Subsidiary, which do
not provide for a classified Board of Directors, will become the bylaws of GZA.

     Currently, the number of directors constituting our full Board of Directors
of the Company is nine, consisting of three directors in each Class. The terms
of the Company's current Class I directors, Rose Ann Giordano, Donald T.
Goldberg and Thomas W. Philbin, expire in 2001. The terms of the Company's
current Class III directors, Timothy W. Devitt, David B. Perini and Andrew P.
Pajak, expire in 2002. The terms of the Company's current Class II directors, M.
Joseph Celi, Lewis Mandell and William E. Hadge, expire immediately following
the 2000 Annual Meeting.

     The Board has nominated Lewis Mandell for re-election and William R. Beloff
and William S. Zoino for election as Class II directors, to serve in the event
that the merger is not approved and consummated. The Board has fixed the number
of directors constituting the full Board of Directors at nine. If they are
elected, and if the merger is not approved and consummated, the term of Messrs.
Mandell, Beloff and Zoino will expire in 2003. Unless marked otherwise, returned
proxies will be voted to elect each of Messrs. Mandell, Beloff and Zoino as the
Class II directors. Each nominee has agreed to serve if he is elected and if the
merger is not approved and consummated, and the Company has no reason to believe
that any of them will be unable to serve. If any nominee is unable or declines
to serve as a director at the time of the Special Meeting, then the Board will
designate another nominee and proxies will be voted in favor of that nominee.

     THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE PROPOSAL
TO ELECT MESSRS. MANDELL, BELOFF AND ZOINO AS THE CLASS II DIRECTORS OF THE
COMPANY.

     The following table sets forth certain information concerning each director
of the Company continuing in office, each nominee for election as director, and

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Compensation Committee of the Board of Directors has furnished the
following report on executive compensation for fiscal year 2000:

     Compensation Policies.  The purpose of the Company's policy for
compensating its executive officers is to establish aggregate compensation
levels that are consistent with the Company's financial performance; to provide
appropriate incentives to promote individual performance and both short-term and
long-term goal achievement, thereby enhancing Company profitability and thus
stockholder value; and to grant total compensation sufficiently competitive to
retain and, when necessary, attract executive officers capable of leading the
Company in the attainment of its business objectives.

     Base Salaries.  The salaries of executive officers are established annually
by evaluating requirements of the position, the contribution of the individual
executive to Company performance and the executive's responsibility, experience
and potential. Base salaries of executive officers are intended to be comparable
to median salaries of a peer group of comparably-sized companies and to salaries
of executive officers reported in an environment industry salary survey. In
making the comparisons, the Company's financial performance as well as
non-financial measures such as contributions to the success of the Company's
strategic plan are considered. In fiscal 1999, the Committee also engaged the
services of an independent compensation consultant to provide advice in
establishing base salaries and short-term and long-term incentives as components
of a total compensation package for senior executives of the Company.

     In keeping with the Compensation Committee's policy of increasing emphasis
on incentive-based compensation for its senior executives, base salaries of the
Company's Chief Executive Officer and other Named Executive Officers were not
increased for fiscal 2000.

     Senior executives are also eligible to participate in various benefit
programs available to all full-time employees in varying degrees, including the
Company's 401(k) Profit Sharing Plan and a supplemental insurance program
whereby term insurance premiums are paid by the Company on behalf of senior
executives and selected other Company employees.

     Incentive Compensation Plan.  Senior executives and other selected Company
employees also may qualify for cash bonuses through participation in the
Company's Incentive Compensation Plan. The amount of the bonus awarded to a
participant is based on achievement of pre-established objectives, including
corporate performance goals (i.e., target earnings before interest, bonus and
taxes) and individual performance goals tied to specific corporate objectives.
For fiscal 2000, the amounts of the target bonuses, assuming the performance
goals were met, ranged from 9.5% to 27.5% of the participants' base salaries. If
the Compensation Committee determines that actual Company performance has
exceeded or fallen short of a participant's pre-established goals, a bonus that
is greater or less than the target bonus may be awarded.

     Long-Term Incentives; Equity-Based Compensation.  Awards of equity-based
compensation have not historically been a significant component of the Company's
compensation of its executive officers, in part, because the Company's senior
executives have often already held significant equity positions in the Company
through ownership of the Company's Common Stock. However, the Compensation
Committee has adopted a new policy under which it plans to provide increased
long-term incentives through awards of equity-based compensation to its
executive officers and other senior executives who are responsible for
significant Company operations, growth opportunities or strategic initiatives.
Under this new policy, a substantial component of the targeted total
compensation package of these senior executives will consist of the expected
future value of awards under the Company's 1999 Stock Incentive Plan, and the
executives' total compensation will therefore increasingly depend on achieving
targeted improvements in the Company's stock price.

     The 1999 Stock Incentive Plan was approved by stockholders at the July 13,
1999 Annual Meeting. In fiscal 2000, the Compensation Committee granted options
to purchase an aggregate of 317,850 shares of Common Stock to the Company's
Chief Executive Officer, its other Named Executive Officers and a limited number
of other senior executives. The options will vest on June 1, 2002, and will
thereafter be exercisable for

                                       54
<PAGE>   57

only nine months. The expected value of these grants, assuming the targeted rate
of growth of the Company's stock price over the vesting period, will range from
approximately 25% to more than 100% of the executive's annual base salary. In
fiscal years after fiscal 2000, and if the merger is not approved, the
Compensation Committee expects to continue to provide long-term incentives in
the form of additional awards of equity-based compensation to selected senior
executives. However, those awards will be smaller in magnitude than the initial
grants described above.

  Chief Executive Officer Compensation

     The base salary of Andrew P. Pajak, the Company's Chief Executive Officer,
increased from $193,003 in fiscal 1999 to $199,556 for fiscal 2000. In fiscal
2000, Mr. Pajak received a bonus of $15,000 compared to approximately $23,467
received for performance in fiscal 1999. This bonus was less than his target
bonus for fiscal 2000, and less than his fiscal 1999 bonus, primarily because
the Committee concluded that the Company had not made adequate progress toward
its goal of expansion through selected acquisitions. In fiscal 2000, Mr. Pajak
and other Named Executive Officers received awards of stock options from the
Long-term Incentive Compensation Plan of FYE 2000-2002, which included a
36,200-share grant to Mr. Pajak. See " -- Long-Term Incentives; Equity Based
Compensation".

     Communications with Stockholders.  The Committee is responsible for
communicating with stockholders regarding the Company's compensation policy and
to ensure that the Board of Directors understands stockholders' perspectives
regarding executive compensation. Members of the Committee may, when
appropriate, respond to stockholder concerns about compensation in subsequent
reports or proxy statements. Comments and questions may be addressed to any
member of the Compensation Committee at GZA GeoEnvironmental Technologies, Inc.,
320 Needham Street, Newton Upper Falls, MA 02464.

                               PERFORMANCE GRAPH

     The following Performance Graph compares the performance of the Company's
cumulative stockholder return with that of a broad market index, the Nasdaq
Stock Market Index for U.S. Companies, and with those equity securities of a
peer group of issuers in the environmental consulting industry selected by the
Company. Issuers in the peer group consist of EA Engineering, Science &
Technology, Inc., Ecology and Environment, Inc., EMCON, Harding Lawson
Associates Group, Inc., Versar, Inc. and Roy F. Weston, Inc. (Fluor Daniel GTI,
Inc., which was included in the Company's peer group in prior years' proxy
statements, has been eliminated from the group due to its acquisition by The IT
Group in December 1998). The cumulative stockholder returns for shares of the
Company's Common Stock and for the market and peer group indices are calculated
assuming $100 was invested on March 1, 1995, and assuming the reinvestment of
dividends, if any, as of the last day of February in each of the five succeeding
years. The Company paid no cash dividends during the periods shown.

                              CERTAIN TRANSACTIONS

     The Company leases certain of its facilities from employees, some of whom
are directors, executive officers or stockholders of the Company, or from
entities in which those persons have interests.

     The Company's principal facility in Newton Upper Falls, Massachusetts is
leased from Donald T. Goldberg, Chairman of the Board of the Company and William
S. Zoino, a beneficial owner of more than five percent of the outstanding Common
Stock of the Company and a nominee for election as a Class II Director. Mr.
Goldberg and Mr. Zoino own the property as tenants in common. Rental payments to
Messrs. Goldberg and Zoino aggregated $714,000 for fiscal 2000.

     The Company's Brockton, Massachusetts facility is leased from GZA
Investment Associates, Trust, a Massachusetts business trust in which the
Company owns a two-thirds interest together with Mr. Zoino and Joseph E. Hebert,
a former employee of GZA Drilling. Lease payments to GZA Investment Associates
Trust totaled $93,000 in fiscal 2000.

     The Company's Providence, Rhode Island facility is leased from GZRI
Associates, a Rhode Island general partnership whose partners are Messrs.
Goldberg and Zoino and four others, Michael A. Powers, David R. Carchedi and
Nicholas A. Campagna, all current employees of GZA GeoEnvironmental, and Frank
W. Clark, a former employee of GZA GeoEnvironmental. Lease payments to GZRI
Associates totaled $80,000 in fiscal 2000.

     The Company believes that the foregoing leases were entered into on terms
no less favorable to the Company than could reasonably have been obtained in
arm's-length transactions with independent third parties.

     The Company provides geotechnical design, instrumentation and consulting
services, on a subcontracting basis, to Perini Corporation and other clients
affiliated with or engaged in joint ventures with Perini Corporation. David B.
Perini, a director of the Company, was the Chairman of the Board of Directors of
Perini Corporation until he retired in July 1999. In fiscal 2000, the Company
billed an aggregate of $2.7 million for services provided to Perini Corporation
and clients affiliated with Perini Corporation.

     Donald T. Goldberg, Chairman of the Board of Directors and formerly the
Company's Chief Executive Officer, is a consultant to the Company and to GZA
GeoEnvironmental, Inc. See "-- Directors' Compensation".

AGREEMENTS WITH EXECUTIVE OFFICERS

     Each of Messrs. Pajak, Simon, Ayres, Celi, Beloff, Hadge and Hehir has
entered into a Non-Competition and Non-Disclosure Agreement with the Company
that provides, among other things, that following the termination of his
employment, and provided that he complies with certain non-competition covenants
set forth in the agreement, he may be entitled to receive, for a period of up to
twelve months following his termination, his base salary and certain other
benefits.

     As noted above, Mr. Pajak expects to leave GZA if the merger is
consummated. In order to retain his services in the meantime, GZA entered into a
retention agreement with Mr. Pajak. Under that agreement, if Mr. Pajak leaves
after the merger, under the circumstances set forth in the retention agreement,
he will receive a severance payment and other benefits, described more fully
under "Interests of Certain GZA Directors, Officers and Stockholders in the
Merger -- Retention Agreement" above.

     The Company has entered into Indemnification Agreements, dated as of June
19, 2000 with each of Messrs. Celi, Devitt, Goldberg, Hadge, Mandell, Pajak,
Perini, Philbin, Ayres, Beloff, Hehir, Simon and Ms. Giordano. The
Indemnification Agreements, provide for indemnification of these persons in
respect of third party proceedings arising out of their service as directors and
officers of the Company, and in respect of proceedings by or in the right of the
Company. The term of each Indemnification Agreement is the later of six years
after the indemnified party ceases to serve as a director or officer of the
Company, or the termination of all proceedings then pending.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Exchange Act requires the Company's directors,
executive officers and persons who own more than ten percent of the outstanding
Common Stock to file with the Commission reports of ownership on Form 3 and
reports of changes in ownership on Forms 4 and 5. Securities and Exchange
Commission regulations require directors, executive officers and
greater-than-ten percent stockholders to furnish the Company with copies of all
Forms 3, 4 and 5 filed with the Commission.

     Based solely upon a review of Forms 3 and 4 that were furnished to the
Company during fiscal 2000, Forms 5 were furnished to the Company by certain
directors and executive officers of the Company with respect to fiscal 2000 and
representation letters of certain other directors and executive officers to the
effect that Form 5 filings were not required, the Company believes that all
Section 16(a) filing requirements applicable to its directors, executive
officers and greater-than-ten-percent stockholders were fulfilled in a timely
manner.

corporation and wholly owned subsidiary of Futureco ("Sub").

                                   RECITALS:

     WHEREAS, each of the Board of Directors and shareholders of Futureco and
the Board of Directors and shareholders of Sub has approved the merger (the
"Merger") of Sub with and into GZA in accordance with the Delaware General
Corporation Law (the "Delaware Law"), this Agreement and the transactions
contemplated hereby, upon the terms and subject to the conditions set forth

     WHEREAS, the Board of Directors of GZA (the "GZA Board"), upon the
recommendation of the special committee of GZA Board established to consider the

and the transactions contemplated hereby and declared their advisability and
resolved to recommend approval and adoption of this Agreement by the
shareholders of GZA;

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby, GZA,
Futureco and Sub hereby agree as follows:

                                   ARTICLE 1

                                   THE MERGER

     SECTION 1.1 The Merger.

     (a) Agreement of Merger.  Prior to the Effective Time (as defined below),
and subject to and upon the terms and conditions of this Agreement, Sub shall be
merged with and into GZA, the separate corporate existence of Sub shall cease
and GZA shall continue as the surviving corporation. GZA as the surviving
corporation after the Merger is hereinafter sometimes referred to as the
"Surviving Corporation."

     (b) Closing.  Subject to the terms and conditions of this Agreement, as
soon as practicable after the satisfaction or waiver of the conditions set forth
in Article 6, the consummation of the Merger will take place, but in no event
later than 3 business days after satisfaction or waiver of the conditions set
forth in Article 6 (the "Closing Date"), at the offices of Bowditch & Dewey,
LLP, 311 Main Street, Worcester, MA 01608, unless another date, time or place is
agreed to in writing by the parties hereto.

     SECTION 1.2 Effective Time.

     On the Closing Date, Sub and GZA shall cause the Merger to be consummated
by filing a certificate of merger (the "Certificate of Merger"), as contemplated
by Delaware Law together with any required related documents, with the Secretary
of State of the State of Delaware, in such form as required by, and executed in
accordance with the relevant provisions of, the Delaware Law (the time of such
filing being the "Effective Time").

     SECTION 1.3 Directors and Officers of Surviving Corporation.

     The directors and the officers of Sub at the Effective Time shall, from and
after the Effective Time, be the directors and officers, respectively, of
Surviving Corporation, until their successors shall have been duly elected or
appointed or qualified or until their earlier death, resignation (including that
provided herein), or removal in accordance with the applicable law.

     SECTION 1.4 Certificate of Incorporation.

     The Certificate of Incorporation of Sub in effect at the Effective Time
shall be the Certificate of Incorporation of Surviving Corporation, until
amended, in accordance with applicable law.
<PAGE>   70

     SECTION 1.5 Bylaws.

     The Bylaws of Sub in effect at the Effective Time shall be the Bylaws of
Surviving Corporation, until amended, in accordance with applicable law.

     SECTION 1.6 Effect of the Merger.

     At the Effective Time, the effect of the Merger shall be as provided in
this Agreement and the Certificate of Merger and the applicable provisions of
the Delaware Law. Without limiting the generality of the foregoing, and subject
thereto, at the Effective Time all the property rights, privileges, powers and
franchises of GZA and Sub shall vest in the Surviving Corporation, and all
debts, liabilities and duties of GZA and Sub shall become the debts, liabilities
and duties of the Surviving Corporation.

     SECTION 1.7 Effect on Capital Stock.

     At the Effective Time, by virtue of the Merger and without any action on
the part of Futureco, Sub, GZA or the holders of any of the following
securities:

          (a) Sub Common Stock.  Each issued and outstanding share of common
     stock, par value $.01 per share, of Sub shall be converted into and become
     one fully paid and nonassessable share of common stock, par value $.01 per
     share, of Surviving Corporation.

          (b) Conversion of GZA Shares.  Each issued and outstanding share of
     common stock, par value $.01 per share, of GZA (the "Shares") immediately
     prior to the Effective Time, including each Option Share, other than a
     Dissenting Share or an Excluded Share, each as hereinafter defined, is
     sometimes referred to as a "Participating Share." Each Participating Share
     shall be cancelled and converted into the right to receive, subject to the
     terms and conditions of this Agreement, $6.40 per Participating Share (the
     "Merger Consideration") payable to the holder thereof, without interest
     thereon, upon the surrender of the certificate formerly representing such
     Participating Share, less any required withholding of taxes; provided,
     however, that any payment due hereunder with respect to an Option Share
     shall be reduced by the exercise price with respect to such Option Share
     (the "Exercise Price Liability"). "Excluded Share" shall mean a Share owned
     by Futureco at the Effective Time and listed on a schedule (the "Excluded
     Securities Schedule") to be delivered to GZA by Futureco at least one
     business day prior to the Closing Date.

          (c) Treasury Shares.  Each Share held in the treasury of GZA, or any
     direct or indirect wholly-owned subsidiary of GZA 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, be canceled and
     retired without payment of any consideration therefor and cease to exist.

          (d) Excluded Shares.  Each Excluded Share shall continue to remain
     issued and outstanding as a share of Surviving Corporation and shall not be
     converted into the right to receive the Merger Consideration.

          (e) Stock Options.  At the Effective Time, each outstanding option
     which is not an Excluded Option, as hereinafter defined, (a "Stock Option")
     to purchase common stock, par value $.01 per share, of GZA ("GZA Common
     Stock") granted under or pursuant to any stock option plan or agreement
     entered into by GZA or any subsidiary thereof (the "GZA Stock Option
     Plans"), as to which the holder has delivered to GZA no later than one (1)
     business day prior to the Closing Date a duly executed Option Exercise
     Agreement in the form annexed hereto as Exhibit A, shall be exercised as of
     the Effective Time pursuant to and in accordance with the terms of the
     applicable Option Exercise Agreement and each share of GZA Common Stock
     issuable upon the exercise of such Stock Option (an "Option Share") shall
     be deemed to have been issued and outstanding immediately prior to the
     Effective Time and to constitute a Participating Share for purposes of this
     Agreement. All Stock Options which are not exercised prior to the Effective
     Time shall be cancelled as of the Effective Time. "Excluded Option" shall
     mean an option to purchase GZA Common Stock listed on the Excluded
     Securities Schedule which options shall be exchanged for options of
     Futureco based upon the exchange ratio set forth on the Excluded Securities
     Schedule.
                                        2
<PAGE>   71

          (f) Dissenting Shares.  Notwithstanding anything in this Agreement to
     the contrary, 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 Delaware Law ("Dissenting Shares") shall not be converted
     into a right to receive the Merger Consideration, but shall be converted
     into the right to receive payment from Surviving Corporation of the fair
     value of such Dissenting Shares in accordance with Delaware Law, unless
     such holder fails to perfect or withdraws or loses his right to appraisal,
     in which case such Shares shall be treated as if they had been converted as
     of the Effective Time into a right to receive the Merger Consideration,
     without interest thereon. GZA shall give Futureco prompt notice of any
     demands received by GZA for appraisal of Shares and, prior to the Effective
     Time, GZA shall consult with Futureco with respect to all negotiations and
     proceedings with respect to such demands. Prior to the Effective Time, GZA
     shall not, except with the prior written consent of Futureco make any
     payment with respect to, or settle or offer to settle, any such demands.

     SECTION 1.8 Exchange of Certificates.

     (a) Exchange Agent and Procedures.  Prior to the Effective Time, a bank or
trust company reasonably acceptable to GZA shall be designated by Futureco (the
"Paying Agent") to act as agent in connection with the Merger to receive the
funds to which holders of Participating Shares shall become entitled hereunder.
No later than one (1) business day after the Effective Time, the Surviving
Corporation shall cause to be mailed to each record holder of a Participating
Share, as of the Effective Time, of a certificate or certificates (the
"Certificates") that, prior to the Effective Time, represented Participating
Shares, a form of letter of transmittal and instructions (in each case
reasonably acceptable to GZA) for use in effecting the surrender of the
Certificates for payment of the Merger Consideration therefor. Within one (1)
business day of the surrender of each such Certificate formerly representing
Participating Shares, together with such letter of transmittal, duly completed
and validly executed in accordance with the instructions thereto, the Paying
Agent shall pay the holder of such Certificate the Merger Consideration
multiplied by the number of Participating Shares formerly represented by such
Certificate, in exchange therefor, and such Certificate shall forthwith be
canceled. Until so surrendered and exchanged, each such Certificate shall
represent solely the right to receive the Merger Consideration. No interest
shall be paid or accrue on the Merger Consideration. If the Merger Consideration
(or any portion thereof) is to be delivered to any person other than the person
in whose name the Certificate formerly representing the Participating Shares
surrendered in exchange therefor is registered, it shall be a condition to such
exchange that the Certificate so surrendered shall be properly endorsed or
otherwise be in proper form for transfer and that the person requesting such
exchange shall pay to the Paying Agent any transfer or other taxes required by
reason of the payment of the Merger Consideration to a person other than the
registered holder of the Certificate surrendered, or shall establish to the
satisfaction of the Paying Agent that such tax has been paid or is not
applicable.

     (b) Consideration.  (i) Immediately prior to the Effective Time (the
"Deposit Date"), the Surviving Corporation and/or Futureco shall deposit, or
cause to be deposited, with the Paying Agent, in trust for the benefit of the
holders of Participating Shares, an amount, in immediately available funds,
equal to the aggregate Merger Consideration to which holders of Participating
Shares shall be entitled at the Effective Time (the "Payment Fund"). The amount
of the Payment Fund shall be determined by (x) multiplying $6.40 by the number
of Participating Shares, and (y) subtracting therefrom the aggregate Exercise
Price Liability for all Participating Shares which are Option Shares.

     (c) Investment of Merger Consideration.  The Merger Consideration shall be
invested by the Paying Agent, as directed by Futureco, and GZA prior to the
Closing Date, provided such investments shall be limited to direct obligations
of the United States of America, obligations for which the full faith and credit
of the United States of America is pledged to provide for the payment of
principal and interest, commercial paper rated of the highest quality by Moody's
Investors Services, Inc. or Standard & Poor's, a division of The McGraw Hill
Companies, Inc., or certificates of deposit issued by a commercial bank having
at least $10,000,000,000 in assets.

                                        3
<PAGE>   72

     (d) Termination of Duties.  Promptly following the date which is one (1)
year after the Effective Time, the Paying Agent shall deliver to the Surviving
Corporation all cash and documents in its possession relating to the Payment
Fund, and the Paying Agent's duties relating thereto shall terminate.
Thereafter, each holder of a Certificate formerly representing a Participating
Share may surrender such Certificate to the Surviving Corporation and (subject
to applicable abandoned property, escheat and similar laws) receive in exchange
therefor the Merger Consideration, without any interest thereon.

     (e) No Liability.  Neither Futureco, Sub, nor the Surviving Corporation
shall be liable to any holder of GZA Common Stock for any Merger Consideration
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.

     (f) Withholding Rights.  The Paying Agent or the Surviving Corporation
shall be entitled to deduct and withhold from the Merger Consideration otherwise
payable pursuant to this Agreement to any holder of GZA Common Stock (i) such
amounts as the Paying Agent is required to deduct and withhold with respect to
the making of such payment under the Internal Revenue Code of 1986, as amended
(the "Code"), or any provision of state, local or foreign tax law, and (ii) with
respect to any Option Share, the Exercise Price Liability. To the extent that
amounts are so withheld by the Paying Agent or the Surviving Corporation, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of the Participating Shares in respect of which such
deduction and withholding was made by the Paying Agent or the Surviving
Corporation.

     SECTION 1.9 No Further Ownership Rights in GZA Common Stock.

     The Merger Consideration delivered upon the surrender for exchange of
Participating Shares in accordance with the terms hereof shall be deemed to have
been issued in full satisfaction of all rights pertaining to such Participating
Shares, and there shall be no further registration of transfers on the records
of the Surviving Corporation of Participating Shares which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving Corporation for any reason, they
shall be canceled and exchanged as provided in this Article 1.

     SECTION 1.10 Lost, Stolen or Destroyed Certificates.

     In the event any Certificates shall have been lost, stolen or destroyed,
the Paying Agent shall deliver in exchange for such lost, stolen or destroyed
Certificates, upon the making of an affidavit of that fact by the holder
thereof, the Merger Consideration; provided, however, that the Paying Agent may,
in its discretion and as a condition precedent to the issuance thereof, require
the owner of such lost, stolen or destroyed Certificates to deliver a bond in
such sum as it may reasonably direct as indemnity against any claim that may be
made against the Surviving Corporation or the Paying Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.

     SECTION 1.11 Taking of Necessary Action; Further Action.

     Each of Futureco, Sub and GZA will take all such reasonable and lawful
action as may be necessary or appropriate in order to effectuate the Merger in
accordance with this Agreement as promptly as possible. If, at any time after
the Effective Time, any such further action is necessary or desirable to carry
out the purposes of this Agreement and to vest the Surviving Corporation with
full right, title and possession to all assets, property, rights, privileges,
powers and franchises of GZA and Sub, the officers and directors of GZA,
Futureco and Sub immediately prior to the Effective Time are fully authorized in
the name of their respective corporations or otherwise to take, and will take,
all such lawful and necessary action.

equivalent) in each jurisdiction in which the nature of its business or the
ownership or leasing of its properties makes such qualification or licensing
necessary, other than in such jurisdictions where the failure to be so qualified
or licensed, individually or in the aggregate, would not have a material adverse
effect on the business, properties, assets, financial condition or results of
operations of GZA and the GZA Subsidiaries (as defined below) taken as a whole
(a "GZA Material Adverse Effect"). Section 2.1 of GZA Disclosure Schedule sets

     legal entity of which such Person (either directly or through or together
     with another Subsidiary of such Person) owns a majority of any of the
     capital stock or other equity interests of such corporation, partnership,
     limited liability company, joint venture or other legal entity or whose

     venture, association, trust, unincorporated organization or any other legal
     entity.

     transfer imposed by federal or state securities laws and regulations and by
     the operating agreement of any such GZA Subsidiary that is a limited
     liability company. Each GZA Subsidiary that is a corporation is duly
     incorporated and validly existing under the laws of its jurisdiction
                                        5

     corporate standing (or the local law equivalent) in each jurisdiction in
     which the nature of its business or the ownership or leasing of its
     properties makes such qualification or licensing necessary, other than in
     such jurisdictions where the failure to be so qualified or licensed,
     individually or in the aggregate, would not have a GZA Material Adverse
     Effect. True and correct copies of the Certificate of Incorporation,
     Bylaws, partnership agreements, joint venture and operating agreements or
     similar organizational documents of each GZA Subsidiary, as amended to the
     date of this Agreement, have been previously delivered to Futureco.

<PAGE>   76

than preliminary material), as of their respective filing dates, or as of the
date of the last amendment thereof (if amended after filing), complied as to
form in all material respects with all applicable requirements of the Securities
Act of 1933, as amended (the "Securities Act"), and the Exchange Act and, in
each case, the rules and regulations promulgated thereunder applicable to such
GZA SEC Documents. None of the GZA SEC Documents at the time of filing contained
any untrue statement of a material fact or omitted 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 to the extent such statements have been modified or
superseded by later GZA SEC Documents filed on a non-confidential basis prior to
the date of this Agreement. The consolidated financial statements of GZA
included in the GZA SEC Documents complied as to form in all material respects
with applicable accounting requirements and the published rules and regulations
of the SEC with respect thereto, have been prepared in accordance with generally
accepted accounting principles ("GAAP") (except, in the case of unaudited
statements, as permitted by the applicable rules and regulations of the SEC)
applied on a consistent basis during the periods involved (except as may be
indicated therein or in the notes thereto) and fairly presented, in accordance
with the applicable requirements of GAAP and the applicable rules and
regulations of the SEC in all material respects, the consolidated financial
position of GZA and the consolidated GZA Subsidiaries, taken as a whole, as of
the dates thereof and the consolidated results of operations and cash flows for
the periods then ended (subject, in the case of unaudited statements, to normal
year-end audit adjustments, any other adjustments described therein and the fact
that certain information and notes have been condensed or omitted in accordance
with the rules and regulations of the SEC). Section 2.6 of the GZA Disclosure
Schedule sets forth all GZA Subsidiaries which are not consolidated for
accounting purposes as of the date hereof. Except for liabilities and
obligations set forth in the GZA SEC Documents or in Section 2.6 of the GZA
Disclosure Schedule or incurred in the ordinary course, neither GZA nor any of
the GZA Subsidiaries has any liabilities or obligations of any nature (whether
accrued, absolute, contingent or otherwise) required by GAAP to be set forth on
a consolidated balance sheet of GZA or in the notes thereto and which,
individually or in the aggregate, would have a GZA Material Adverse Effect,
after taking into account any assets acquired or services provided in connection
with the incurrence of such liabilities or obligations.

     SECTION 2.7 Absence of Certain Changes or Events.

     Except as disclosed in the GZA SEC Documents or Section 2.7 of the GZA
Disclosure Schedule, since the date of the most recent audited financial
statements included in the GZA SEC Documents (the "GZA Financial Statement
Date"), GZA and the GZA Subsidiaries have conducted their business only in the
ordinary course (taking into account prior practices, including the acquisition
of properties and issuance of securities) and there has not been (a) any
material adverse change in the business, financial condition or results of
operations of GZA and the GZA Subsidiaries taken as a whole (a "GZA Material
Adverse Change"), nor, to the Knowledge of GZA, has there been any occurrence or
circumstance that with the passage of time would reasonably be expected to
result in a GZA Material Adverse Change, (b) any declaration, setting aside or
payment of any dividend or other distribution (whether in cash, stock or
property) with respect to any GZA Common Stock, (c) any split, combination or
reclassification of any GZA Common Stock or any issuance or the authorization of
any issuance of any other securities in respect of, in lieu of or in
substitution for, or giving the right to acquire by exchange or exercise, shares
of its beneficial interest or any issuance of an ownership interest in, any GZA
Subsidiary except as contemplated by this Agreement, (d) any damage, destruction
or loss, whether or not covered by insurance, that has or would have caused or
created a GZA Material Adverse Effect, (e) any change made prior to the date of
this Agreement in accounting methods, principles or practices by GZA or any GZA
Subsidiary materially affecting its assets, liabilities or business, except
insofar as may have been disclosed in GZA SEC Documents or required by a change
in GAAP, or (f) any amendment of any employment, consulting, severance,
retention or any other agreement between GZA and any officer or director of GZA.

     SECTION 2.8 Litigation.

     Except as disclosed in the GZA SEC Documents, Section 2.8 or Section 2.9 of
the GZA Disclosure Schedule, there is no suit, action or proceeding pending or,
to the Knowledge of GZA, threatened against or affecting GZA or any GZA
Subsidiary that, individually or in the aggregate, could reasonably be expected
to
                                        8
<PAGE>   77

(i) have a GZA Material Adverse Effect or (ii) prevent the consummation of any
of the transactions contemplated by this Agreement, nor is there any judgment,
decree, injunction, rule or order of any Governmental Entity or arbitrator
outstanding against GZA or any GZA Subsidiary having, or which could reasonably
be expected to have, any such effect. Notwithstanding the foregoing, (y) Section
2.8 of the GZA Disclosure Schedule sets forth each and every claim that GZA has
Knowledge of involving a potential dollar cost to GZA in excess of $50,000
(identifying which are covered by insurance) including equal employment
opportunity claims, and claims relating to sexual harassment and/or
discrimination as of the date hereof, in each case with a brief summary of such
claim and (z) no claim is pending or has been made under any directors' or
officers' liability insurance policy maintained at any time by GZA or any of the
GZA Subsidiaries.

     SECTION 2.9 Properties.

     (a) Section 2.9 of the GZA Disclosure Schedule identifies all real property
owned by GZA and the GZA Subsidiaries (the "GZA Properties"). Except as provided
in Section 2.9 of the GZA Disclosure Schedule, GZA and the GZA Subsidiaries set
forth on Section 2.2 of the GZA Disclosure Schedule own fee simple title to
their respective GZA Properties. Except as set forth on Section 2.9 of the GZA
Disclosure Schedule, all such properties are owned in each case free and clear
of liens, mortgages or deeds of trust, claims against title, charges which are
liens, security interests or other encumbrances on title securing monetary
obligations ("Encumbrances"). Except as set forth in Section 2.2, Section 2.9 or
Section 2.18 of the GZA Disclosure Schedule, no other Person has any ownership
interest in any of the GZA Properties, and any such ownership interest so
scheduled does not materially detract from the value of, or materially interfere
with the present use of, any of the GZA Properties subject thereto or affected
thereby. To GZA's Knowledge, GZA Properties are not subject to any rights of
way, written agreements, laws, ordinances and regulations affecting building use
or occupancy, or reservations of an interest in title (collectively, "Property
Restrictions") or other Encumbrances, except for (i) Encumbrances and Property
Restrictions set forth in the GZA Disclosure Schedule, (ii) Property
Restrictions imposed or promulgated by law or any governmental body or authority
with respect to real property, including zoning regulations, provided they do
not materially adversely affect the current use of any GZA Property, (iii)
Encumbrances and Property Restrictions of record, which Encumbrances and
Property Restrictions, in any event, do not materially detract from the value
of, or materially interfere with the present use of, any of GZA Properties
subject thereto or affected thereby, (iv) real estate taxes and assessments
which constitute a lien but are not yet due and payable and (v) mechanics',
carriers', workmen's, repairmen's liens, other Encumbrances and Property
Restrictions, if any, which, individually or in the aggregate, do not materially
detract from the value of or materially interfere with the present use of any of
GZA Properties subject thereto or affected thereby, and do not otherwise
materially impair business operations conducted by GZA and the GZA Subsidiaries.

     (b) Section 2.9 of the GZA Disclosure Schedule also identifies all real
property leased by GZA and the GZA Subsidiaries (the "GZA Leased Properties").
Except as set forth in Section 2.9 of the GZA Disclosure Schedule, all such
properties are leased pursuant to leases that are in full force and effect on
the date of this Agreement and, with GZA and the GZA Subsidiaries not being in
material default under such leases and with the lessors thereof, to the
Knowledge of GZA, also not being in material default thereunder. GZA has
previously delivered to Futureco true and correct copies of such leases. GZA
Leased Properties are not, to the Knowledge of GZA, subject to any Property
Restrictions or other Encumbrances, except for (i) Encumbrances and Property
Restrictions set forth in the GZA Disclosure Schedule, (ii) Property
Restrictions imposed or promulgated by law or any governmental body or authority
with respect to real property, including zoning regulations, provided they do
not materially adversely affect the current use of any GZA Leased Property,
(iii) Encumbrances and Property Restrictions of record, which Encumbrances and
Property Restrictions, in any event, do not materially detract from the value
of, or materially interfere with the present use of, any of GZA Leased
Properties subject thereto or affected thereby, (iv) real estate taxes and
assessments which constitute a lien but are not yet due and payable and (v)
mechanics', carriers', workmen's, repairmen's liens, other Encumbrances and
Property Restrictions, if any, which, individually or in the aggregate, do not
materially detract from the value of or materially interfere with the present
use of any of

                                        9
<PAGE>   78

GZA Leased Properties subject thereto or affected thereby, and do not otherwise
materially impair business operations conducted by the GZA Subsidiaries.

     (c) Except as provided in Section 2.9 of the GZA Disclosure Schedule, GZA
has no Knowledge (i) that, any certificate, permit or license from any
governmental authority having jurisdiction over any of the GZA Properties or any
agreement, easement or other right which is necessary to permit the lawful use
and operation of the buildings and improvements on any of the GZA Properties or
which is necessary to permit the lawful use and operation of all driveways,
roads and other means of egress and ingress to and from any of the GZA
Properties has not been obtained and is not in full force and effect, or of any
pending threat of modification or cancellation of any of same; or (ii) of any
written notice of any violation of any federal, state or municipal law,
ordinance, order, regulation or requirement materially and adversely affecting
any of the GZA Properties issued by any governmental authority.

     (d) GZA and each of the GZA Subsidiaries have good and sufficient title to
all their personal and non-real properties and assets reflected as being owned
by them in the consolidated balance sheet of GZA as of the GZA Financial
Statement Date, except as since sold or otherwise disposed of in the ordinary
course of business), free and clear of all liens and encumbrances, except such
Encumbrances reflected on Section 2.9 or Section 2.18 of the GZA Disclosure
Schedule or on the consolidated balance sheet of GZA as of the GZA Financial
Statement Date, and the notes thereto, and except for liens for current taxes
not yet due and payable, and Liens or Encumbrances which are normal to the
business of GZA and the GZA Subsidiaries and are not, in the aggregate, material
in relation to the assets of GZA on a consolidated basis and except also for
such imperfections of title, easement and encumbrances, if any, as do not
materially interfere with the present use of the properties subject thereto or
affected thereby, or otherwise materially impair the consolidated business
operations of GZA.

     SECTION 2.10 Environmental Matters.

     GZA has delivered to Futureco a true and complete copy of the environmental
reports listed on Section 2.10 of the GZA Disclosure Schedule (the "GZA
Environmental Reports"). To GZA's Knowledge, the GZA Environmental Reports
constitute all final environmental reports (including, without limitation, all
final versions of environmental investigations and testing or laboratory
analysis made by or on behalf of GZA or any of the GZA Subsidiaries) with
respect to the GZA Properties or the GZA Leased Properties in the possession of
GZA or any GZA Subsidiary. With respect to each GZA Property or GZA Leased
Property except for any condition that individually or in the aggregate would
not be reasonably likely to have a GZA Material Adverse Effect, to the Knowledge
of GZA (a) no Hazardous Substances (as defined below) have been used, stored,
manufactured, treated, processed or transported to or from any such GZA Property
or GZA Leased Property, except as necessary to the conduct of business and in
compliance with Environmental Laws (as defined below); (b) no unlawful spills,
releases, discharges or disposals of Hazardous Substances have occurred or are
presently occurring on or from such GZA Property or GZA Leased Property; (c)
such GZA Property or GZA Leased Property and the business conducted thereon are
not in violation of Environmental Laws; and (d) GZA and the GZA Subsidiaries
have not received, nor had communications with third parties which would lead
them to reasonably expect to receive, any notice of potential responsibility,
letter of inquiry or notice of alleged liability under any Environmental Law
from any Person regarding such GZA Property or the business conducted thereon.
For the purposes of this Section 2.10 only, "GZA Properties" shall be deemed to
include all property formerly owned by GZA or the GZA Subsidiaries; solely,
however, as to the period of time when such formerly owned property was owned by
GZA or the GZA Subsidiaries.

     "Environmental Laws" shall mean any applicable statute, code, enactment,
ordinance, rule, regulation, permit, consent, approval, authorization, judgment,
order, common law rule (including without limitation the common law respecting
nuisance and tortious liability), decree, injunction, or other requirement
having the force and effect of law, whether local, county, state, territorial or
national, at the date of this Agreement or at any prior time in force or effect
relating to:

          (a) emissions, discharges, spills, releases or threatened releases of
     Hazardous Substances into ambient air, surface water, groundwater,

Section 2.11 of the GZA Disclosure Schedule. As used in this Agreement, the term

and the rules and regulations promulgated thereunder ("ERISA") ("Pension Plan"),
and any welfare plan as defined in Section 3(1) of ERISA ("Welfare Plan")),
whether any of the foregoing is funded, insured or self-funded, written or oral,
(i) sponsored or maintained by GZA or the GZA Subsidiaries (each a "Controlled
Group Member") and covering any Controlled Group Member's active or former
employees (or their beneficiaries), (ii) to which any Controlled Group Member is
a party or by which any Controlled Group Member (or any of the rights,
properties or assets thereof) is bound or (iii) with respect to which any
current Controlled Group Member may otherwise have any material liability
(whether or not such Controlled Group

                                       11
<PAGE>   80

Member still maintains such GZA Employee Plan). Each GZA Employee Plan is listed
on Section 2.12 of the GZA Disclosure Schedule. With respect to GZA Employee
Plans:

          (a) Except as disclosed in the GZA SEC Documents or in Section 2.12 of
     the GZA Disclosure Schedule, no Controlled Group Member has any continuing
     liability under any Welfare Plan which provides for continuing benefits or
     coverage for any participant or any beneficiary of a participant after such
     participant's termination of employment, except as may be required by
     section 4980B of the Code or Section 601 (et seq.) of ERISA, or under any
     applicable state law, and at the expense of the participant or the
     beneficiary of the participant.

          (b) Each GZA Employee Plan complies in all material respects with the
     applicable requirements of ERISA, if any, and any other applicable law
     governing such GZA Employee Plan; and each GZA Employee Plan has to GZA's
     Knowledge at all times been properly administered in all material respects
     and is presently being administered in all material respects in accordance
     with all such requirements of law, and in accordance with its terms and the
     terms of any applicable collective bargaining agreement to the extent
     consistent with all such requirements of law. Each Pension Plan which is
     intended to be qualified is qualified under Section 401(a) of the Code, has
     received a favorable determination letter from the Internal Revenue Service
     (the "IRS") stating that such Plan meets the requirements of Section 401(a)
     of the Code and that the trust associated with such Plan is tax exempt
     under Section 501(a) of the Code, and no event has occurred which, to GZA's
     Knowledge, would be likely to jeopardize the qualified status of any such
     plan or the tax exempt status of any such trust under Sections 401(a) and
     Section 501(a) of the Code, respectively. GZA has received no notice of any
     lawsuit, claim or complaint (other than routine claims for benefits) or
     complaints to, or by, any person or governmental entity with respect to any
     GZA Employee Plan and to the Knowledge of GZA there is no fact which would
     reasonably be expected to give rise to any such lawsuit, claim (other than
     routine claims for benefits) or complaint with respect to any GZA Employee
     Plan. Without limiting the foregoing, except as disclosed on Section 2.12
     of the GZA Disclosure Schedule, the following are true with respect to each
     GZA Employee Plan:

             (i) except for those not yet required to be filed or distributed,
        all Controlled Group Members have filed or caused to be filed every
        material return, report, statement, notice, declaration and other
        document required by any law or governmental agency, federal, state and
        local (including, without limitation, the IRS and the United States
        Department of Labor) with respect to each such GZA Employee Plan, each
        of such filings has been complete and accurate in all material respects
        and no Controlled Group Member has incurred any material liability in
        connection with such filings;

             (ii) except for those not yet required to be filed or distributed,
        all Controlled Group Members have delivered or caused to be delivered to
        every participant, beneficiary and other party entitled to such
        material, all material plan descriptions, returns, reports, schedules,
        notices, statements and similar materials, including, without
        limitation, summary plan descriptions and summary annual reports, as are
        required under Title I of ERISA, the Code, or both, and no Controlled
        Group Member has incurred any material liability in connection with such
        deliveries;

             (iii) all contributions and payments with respect to GZA Employee
        Plans that are required to be made by a Controlled Group Member with
        respect to periods ending on or before the Closing Date (including
        periods from the first day of the current plan or policy year to the
        Closing Date) have been, or will be, made or accrued before the Closing
        Date in accordance with the appropriate plan document, actuarial report,
        collective bargaining agreements or insurance contracts or arrangements
        or as otherwise required by ERISA or the Code; and

             (iv) with respect to each such GZA Employee Plan, to the extent
        applicable, GZA has delivered to Futureco true and complete copies of
        (A) current plan documents, or any and all other documents that
        establish the existence of the current plan, trust, arrangement,
        contract, policy or commitment and all amendments thereto, (B) the most
        recent determination letter, if any, received from the IRS, (C) the
        three most recent Form 5500 Annual Report (and all schedules and reports

                                       12
<PAGE>   81

        relating thereto) and actuarial reports and (D) all related trust
        agreements, insurance contract or other funding agreements that
        implement each such GZA Employee Plan.

          (c) With respect to each GZA Employee Plan, there has not occurred,
     and no person or entity is contractually bound to enter into, any
     "prohibited transaction" within the meaning of Section 4975(c) of the Code
     or Section 406 of ERISA, which transaction is not exempt under Section
     4975(d) of the Code or Section 408 of ERISA.

          (d) Except as disclosed in Section 2.12 of the GZA Disclosure
     Schedule, no Controlled Group Member has maintained or been obligated to
     contribute to any GZA Employee Plan subject to Code Section 412 or Title IV
     of ERISA. With respect to each GZA Employee Plan set forth on Section 2.12A
     of the GZA Disclosure Schedule, GZA represents that each such GZA Employee
     Plan has been completely terminated in accordance with all Code and ERISA
     requirements for a "standard termination" (as defined in 4041(b) of ERISA),
     as applicable on the termination date.

          (e) Except as set forth in Section 2.12 of the GZA Disclosure
     Schedule, with respect to each Pension Plan maintained by any Controlled
     Group Member, such Plans provide the Plan Sponsor the authority to amend or
     terminate the plan at any time, subject to applicable requirements of ERISA
     and the Code.

     SECTION 2.13 Employee Matters.

     Section 2.13 of the GZA Disclosure Schedule lists the employee handbooks of
GZA and each of the GZA Subsidiaries currently in effect. A true and correct
copy of each such employee handbook has previously been made available to
Futureco. Except as set forth in Section 2.13 of the GZA Disclosure Schedule,
such handbooks fairly and accurately summarize all material employee policies,
vacation policies and payroll practices of GZA and the GZA Subsidiaries. Neither
GZA nor any of the GZA Subsidiaries is a party to, or bound by, any collective
bargaining agreement, contract or other agreement or understanding with a labor
union or other labor organization, nor has GZA or any of the GZA Subsidiaries
agreed that any unit of their employees is appropriate for collective
bargaining. No union or other labor organization has been certified as
bargaining representative for any of GZA's employees. To the Knowledge of GZA
there are no organizational efforts with respect to the formation of a
collective bargaining unit presently being made or threatened involving
employees of GZA or any of the GZA Subsidiaries.

     SECTION 2.14 Taxes.

     (a) Tax Returns.  All Tax Returns required to have been filed on or prior
to the date hereof or the Closing Date by GZA or any GZA Subsidiary have been or
will be filed on or prior to the due date for such Tax Return and such Tax
Returns are true and correct in all material respects. In particular, the
foregoing Tax Returns are not subject to penalties under Section 6662 of the
Code, relating to accuracy-related penalties (or any corresponding provision of
the state, local or foreign Tax law) or any predecessor provision of law. Except
as set forth on Section 2.14(a) of the GZA Disclosure Schedule, an extension of
time within which to file any Tax Return that has not been filed has not been
requested or granted. As used in this Agreement, the term "Affiliated Group"
shall mean an affiliated group as defined in Section 1504 of the Code (or any
analogous combined, consolidated or unitary group defined under state, local or
foreign income Tax law) of which GZA is or has been a member.

     (b) Payment of Taxes.  With respect to all amounts of Taxes imposed on GZA,
any GZA Subsidiary or for which GZA or any GZA Subsidiary is or could be liable,
whether to taxing authorities or to other persons or entities (as, for example,
under Tax allocation agreements), with respect to all taxable periods or
portions of periods ending on or before the Closing Date, all applicable Tax
laws and agreements have been fully complied with except where the failure to
comply would not have a Material Adverse Effect on GZA and all such amounts
required to be paid by GZA or any GZA Subsidiary to taxing authorities or others
on or before the Closing Date have been paid, or have been accrued for or fully
reserved against on the Financial Statements.

                                       13

     (c) Audit History.  Except as set forth on Section 2.14(c) of the GZA
Disclosure Schedule, with respect to all federal income tax returns of GZA for

Internal Revenue Service, any deficiencies or assessments, including interest
and penalties thereon, claimed or made as a result of those examinations have
been paid or are fully reserved against on the Financial Statements. Except as
set forth on Section 2.14(c) of the GZA Disclosure Schedule, no issues have been
raised or, to the Knowledge of GZA or any of the GZA Subsidiaries, are currently
pending by any taxing authority in connection with any of the Tax Returns of GZA
or any of the GZA Subsidiaries. Except as set forth on Section 2.14(c) of the
GZA Disclosure Schedule, to the Knowledge of GZA, no issue has been raised by
any taxing authority in any audit of GZA or any member of the Consolidated Group
that, if raised with respect to any other period not so audited, could be
expected to result in a proposed deficiency for any period so audited. Except as
set forth on Section 2.14(c) of the GZA Disclosure Schedule, no waivers of
statutes of limitation with respect to the Tax Returns have been given by or
requested from GZA or any Affiliates of such parties. Section 2.14(c) of the GZA
Disclosure Schedule sets forth, with respect to the taxable years of GZA and any
of the GZA Subsidiaries, those years for which examinations have not been
initiated, and those years for which required Tax Returns have not yet been
filed. Except to the extent shown on Section 2.14(c) of the GZA Disclosure
Schedule, all deficiencies asserted or assessments made as a result of any
examinations have been fully paid.

     (d) Liens.  There are no liens for Taxes (other than for current Taxes not
yet due and payable) on any of the assets of GZA or any of the GZA Subsidiaries.

     (e) Tax-sharing or Allocation Agreements.  Any Tax-indemnity, Tax-sharing,
Tax allocation or similar agreements of GZA or any of the GZA Subsidiaries and
any liability or obligation of GZA or any of the GZA Subsidiaries under such
agreements will terminate as of the Closing Date and be of no further force or
effect. All such agreements to which GZA or any of the GZA Subsidiaries is a
party and are now in effect are listed on Section 2.14(e) of the GZA Disclosure
Schedule. Any payments pursuant to such agreements that were not reflected in
the Financial Statements, are disclosed on Section 2.14(e) of the GZA Disclosure
Schedule.

     (f) Prior Affiliated Groups.  Except as set forth on Section 2.14(f) of the
GZA Disclosure Schedule, neither GZA nor any of the GZA Subsidiaries has ever

of Futureco which consent will not be unreasonably withheld or delayed and,
except as required by law, except as necessary or appropriate in the opinion of
GZA's independent auditors in order to comply with GAAP or SEC requirements, no
method of accounting of GZA will be changed without the written consent of
Futureco, which consent will not be unreasonably withheld or delayed.

     (h) Certain Consents and Elections.  (i) Neither GZA nor any Affiliated
Group in which GZA is or was a member has filed a consent pursuant to the

any agreement, contract, arrangement, or plan that has resulted or would result,
separately or in the aggregate, in the payment of any

     or encourage, directly or indirectly, any inquiries or the making or

     proposal or offer to its shareholders) with respect to a merger,

     similar transaction involving all or any significant portion of the assets

     to, or have any discussions with, any person relating to an Acquisition
     Proposal, or otherwise facilitate any effort or attempt to make or

<PAGE>   90

     Acquisition Proposal; provided, however, that nothing contained in this
     Section 4.1 shall prohibit GZA or the Special Committee or their agents and
     representatives from (i) continuing to discuss and negotiate an Acquisition
     Proposal with any party initially contacted by or on behalf of GZA prior to
     the execution of this Agreement and to provide information to and cooperate
     with such parties; provided the Special Committee in good faith reasonably
     believes that such negotiation could lead to a Superior Acquisition
     Proposal; (ii) furnishing information to or entering into discussions or
     negotiations with, any person or entity that makes an unsolicited
     Acquisition Proposal, if, and only to the extent that (A) the Special

     lead to a Superior Acquisition Proposal, and that failure to do so could
     constitute a breach of the duties of the directors of GZA to the holders of
     the Shares, and (B) GZA shall promptly notify Futureco of such Acquisition
     Proposal and any Acquisition Proposal made pursuant to subparagraph c(i)
     hereof and keep Futureco informed of the status thereof. Nothing in this
     Section 4.1 shall (x) permit GZA to terminate this Agreement (except as
     specifically provided in Article 7 hereof, nor shall GZA terminate this
     Agreement pursuant to the provisions of Article 7, unless and until it
     shall have advised Futureco of the proposed terms and conditions of the
     proposed Superior Acquisition Proposal and given Futureco a reasonable time
     to respond), (y) permit GZA to enter into a definitive agreement with
     respect to an Acquisition Proposal during the term of this Agreement it

     facilitates an Acquisition Proposal (other than a confidentiality agreement
     in customary form executed as provided above)or (z) affect any other
     obligation of GZA under this Agreement; provided, however, that, subject to
     the provisions of Section 7.2, the GZA Board, upon the recommendation of
     the Special Committee, may approve and recommend a Superior Acquisition
     Proposal and, in connection therewith, withdraw or modify its approval or
     recommendation of this Agreement and the Merger. As used herein, "Superior
     Acquisition Proposal" means a bona fide Acquisition Proposal made by a
     third party which the Special Committee determines in good faith after
     consultation with its financial advisor to be (I) more favorable to GZA's

     capable of being consummated within a reasonable period of time.

qualified becomes untrue or inaccurate in any material respect or (ii) of the
failure by it to comply with or satisfy in any material respect any covenant,

advancement of expenses provided to the Indemnified Parties by GZA (including
advancement of expenses, if so provided) immediately prior to the Effective Time
in its Certificate of Incorporation, Bylaws and existing contractual agreements
(the "Indemnification Agreements") as in effect at the close of business on the

     (b) The provisions of this Section 5.8 are intended to be for the benefit
of, and shall be enforceable by, each Indemnified Party, his or her heirs and
his or her personal representatives and shall be binding on all successors and
assigns of the Surviving Corporation. The Surviving Corporation shall pay all
costs and expenses (including fees and expenses of counsel) that may be incurred
by any Indemnified Party or his or her heirs or his or her personal
representatives in successfully enforcing the indemnity or other obligations of
Futureco or the Surviving Corporation under this Section 5.8. The provisions of
this Section 5.8 shall survive the Merger and are in addition to any other
rights to which an Indemnified Party may be entitled.

<PAGE>   95

     (c) In the event that the Surviving Corporation or any of its respective
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person, then, and in each such case the successors
and assigns of such entity shall assume the obligations set forth in this
Section 5.8, which obligations are expressly intended to be for the irrevocable
benefit of, and shall be enforceable by, each director and officer covered
hereby.

their respective officers or directors shall enter into any Stock Agreement with
any third party except Stock Agreements with employees of GZA necessary in order
to determine the composition of the Excluded Securities Schedule which

Shareholder Approval.

Special Committee of the Board of Directors
GZA GeoEnvironmental Technologies, Inc.
320 Needham Street
Newton Falls, MA 02464

Dear Ladies and Gentlemen:

     We understand that GZA GeoEnvironmental Technologies, Inc. ("GZA or the
"Company") has received an offer from Futureco Environmental, Inc. to acquire
all of the outstanding common stock of the Company for $6.40 per share. Certain
officers, directors or shareholders of Futureco Environmental, Inc. are also
employees or shareholders of GZA. All other common stockholders of the Company
are referred to herein as the "Public Stockholders." Such transaction and all
related transactions are referred to collectively herein as the "Transaction."

     In connection with this Opinion, we have made such reviews, analyses and
inquiries as we have deemed necessary and appropriate under the circumstances.
Among other things, we have:

          1. reviewed the Company's annual reports to shareholders and on Form
     10-K for the five fiscal years ended February 29, 2000 and quarterly
     reports on Form 10-Q for the quarter ended May 31, 2000, which the
     Company's management has identified as being the most current financial
     statements available;

          2. reviewed the Draft Agreement and Plan of Merger dated August 7,
     2000;

          3. met with certain members of the senior management of the Company to
     discuss the operations, financial condition, future prospects and projected
     operations and performance of the Company;

          4. visited certain facilities and business offices of the Company;

          5. reviewed forecasts and projections prepared by the Company's
     management with respect to the Company for the year ending February 28,
     2001;

          6. reviewed the historical market prices and trading volume for the
     Company's publicly traded securities;

          7. reviewed certain other publicly available financial data for
     certain companies that we deem comparable to the Company, and publicly
     available prices and premiums paid in other transactions that we considered
     similar to the Transaction;

          8. reviewed drafts of certain documents to be delivered at the closing
     of the Transaction;

          9. at the request of the Special Committee of GZA's Board of
     Directors, approached and held discussions with third parties to solicit
     indications of interest in the possible acquisition of GZA; and

          10. conducted such other studies, analyses and inquiries as we have
     deemed appropriate.

     We have relied upon and assumed, without independent verification, that the
financial forecasts and projections provided to us have been reasonably prepared
and reflect the best currently available estimates of the future financial
results and condition of the Company, and that there has been no material change
in the assets, financial condition, business or prospects of the Company since
the date of the most recent financial statements made available to us.

     We have not independently verified the accuracy and completeness of the
information supplied to us with respect to the Company and do not assume any
responsibility with respect to it. We have not made any physical inspection or
independent appraisal of any of the properties or assets of the Company. Our
opinion is necessarily based on business, economic, market and other conditions
as they exist and can be evaluated by us at the date of this letter.

     The Company, like other companies and any business entities analyzed by
Houlihan Lokey or which are otherwise involved in any manner in connection with
this Opinion, could be materially affected by complications that may occur, or
may be anticipated to occur, in computer-related applications as a result of the
year change from 1999 to 2000 (the "Y2K Issue"). In accordance with
long-standing practice and procedure, Houlihan Lokey's services are not designed
to detect the likelihood and extent of the effect of the Y2K Issue, directly or
indirectly, on the financial condition and/or operations of a business. Further,
Houlihan Lokey has no responsibility with regard to the Company's efforts to
make its systems, or any other systems (including its vendors and service
providers), Year 2000 compliant on a timely basis. Accordingly, Houlihan Lokey
shall not be responsible for any effect of the Y2K Issue on the matters set
forth in this Opinion.

     This Opinion does not constitute a recommendation to the Special Committee
of the Board of Directors, the Board of Directors or any shareholder of the
Company as to how to vote in connection with the Transaction.

     Based upon the foregoing, and in reliance thereon, it is our opinion that
the consideration to be received by the Public Stockholders of the Company in
connection with the Transaction is fair to them from a financial point of view.

     This Opinion is for the use and benefit of the Special Committee of the
Board of Directors and the Board of Directors of the Company in its evaluation
of the Transaction and shall not be used by any other person without the prior
written consent of Houlihan Lokey Howard & Zukin Capital.

                        DELAWARE GENERAL CORPORATION LAW

                             TITLE 8. CORPORATIONS

                           sec.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 sec.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 of 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 sec.251 (other than a merger effected pursuant to
sec.251(g) of this title), sec.252, sec.254, sec.257, sec.258, sec.263 or
sec.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 (f) of sec.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
     sec.sec.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 sec.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.
<PAGE>   107

          (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 subsection (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 sec.228 or
     sec.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
     consolidation, the record date shall be such effective date. If no record
     date is fixed and the notice is given prior to the effective date, the
     record date shall be the close of business on the day next preceding the
     day on which the notice is given.

     (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 1 or more publications at
least 1 week before the day 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 (f) 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
                                        3
<PAGE>   109

other decrees in the Court of 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.
