               WE ARE PROPOSING THAT YOU VOTE TO APPROVE A MERGER
                          YOUR VOTE IS VERY IMPORTANT

    The boards of directors of Casella Waste Systems, Inc. and KTI, Inc. have
agreed to merge. We are seeking your vote on this important transaction.

    If the merger is completed, KTI shareholders will receive 0.51 of a share of
Casella Class A common stock for each share of KTI common stock that they own.
Based upon the number of outstanding shares of Casella common stock and KTI
common stock as of October 1, 1999, KTI shareholders immediately prior to the
merger are expected to own approximately 30.88% of the outstanding shares of
Casella common stock immediately after the merger, representing approximately
22.31% of the votes entitled to be cast by Casella stockholders after the
closing of the merger. Casella stockholders will continue to own their existing
shares after the merger. Casella Class A common stock is traded on the Nasdaq
National Market under the symbol "CWST".

    The merger cannot be completed unless KTI shareholders approve the merger
agreement and Casella stockholders approve the issuance of shares of Casella
Class A common stock to KTI shareholders. In addition, Casella stockholders are
being asked to vote on other matters that are described in this proxy
statement/prospectus. Casella stockholders will vote on their proposals at
Casella's 1999 annual meeting and KTI shareholders will vote on their proposals
at a special meeting.

    Whether or not you plan to attend your stockholders meeting, please take the
time to vote by completing and mailing the enclosed proxy card in the enclosed
envelope. If you sign, date and mail your proxy card without indicating how you
want to vote, your proxy will be counted as a vote in favor of the proposals
submitted at your stockholders meeting.

    THIS SUMMARY HIGHLIGHTS SELECTED INFORMATION FROM THIS PROXY
STATEMENT/PROSPECTUS. IT MAY NOT CONTAIN ALL OF THE INFORMATION THAT IS
IMPORTANT TO YOU IN ORDER TO UNDERSTAND THE MERGER FULLY OR THE OTHER PROPOSALS
TO BE VOTED ON AT YOUR STOCKHOLDERS MEETING. FOR A MORE COMPLETE DESCRIPTION OF

THE COMPANIES (PAGES 59 THROUGH 131)

    Casella Waste Systems, Inc.
    25 Greens Hill Lane
    Rutland, Vermont 05701
    (802) 775-0325

    Casella is a regional, integrated, non-hazardous solid waste services
company that provides collection, transfer, disposal and recycling services in
Vermont, New Hampshire, Maine, upstate New York, northern Pennsylvania and
Massachusetts. At September 1, 1999, Casella owned and/or operated five Subtitle
D landfills and two permitted construction and demolition debris landfills, 54
transfer stations, 24 recycling processing facilities and 38 collection
operations which together serve over 500,000 commercial, municipal and
residential customers. Subtitle D landfills are solid waste landfills that must
be built, operated and then maintained after they stop operating in accordance
with state and federal regulations, commonly referred to as Subtitle D.

    KTI, Inc.
    7000 Boulevard East
    Guttenberg, New Jersey 07093
    (201) 854-7777

    KTI is an integrated solid waste processing company serving commercial,
industrial and residential customers primarily in the eastern United States. At
September 1, 1999, KTI processed solid waste through a network of 50 facilities
in 19 states, including six waste-to-energy plants, 22 material recycling
facilities and 11 finished products facilities.

THE MERGER (PAGES 25 THROUGH 58)

    WHAT KTI SHAREHOLDERS WILL RECEIVE IN THE MERGER.  As a result of the
merger, KTI will become a direct, wholly-owned subsidiary of Casella. Each KTI
shareholder will receive 0.51 of a share of Casella Class A common stock in
exchange for each share of KTI common stock that they own. The exact number of
shares of Casella Class A common stock issuable because of the merger will
depend on the number of shares of KTI common stock, options, warrants and
convertible notes outstanding immediately prior to the merger. Casella will not
issue fractional shares in the merger. Instead, KTI shareholders will receive
cash for any fraction of a share of Casella Class A common stock to which he or
she becomes entitled.

    WHAT KTI OPTIONHOLDERS AND WARRANTHOLDERS WILL RECEIVE IN THE MERGER.  KTI
options and warrants outstanding and unexercised at the time of the merger will
be converted into rights to acquire Casella Class A common stock under the same
terms on which outstanding shares are to be exchanged, provided that the number
of shares will decrease and the exercise price per share will increase to
reflect the exchange ratio. For example, an option to purchase 100 shares of KTI
common stock at an exercise price of $10.00 per share will become an option to
purchase 51 shares of Casella Class A common stock at an exercise price of
$19.61 per share.

    WHAT CASELLA STOCKHOLDERS WILL RECEIVE IN THE MERGER.  Holders of Casella
Class A common stock will continue to own their existing shares after the
merger. However, as a result of the merger, they will own shares of a larger,
more diversified company, as described in this proxy statement/prospectus.
<PAGE>

KTI SHAREHOLDERS' OWNERSHIP OF CASELLA AFTER THE MERGER

    Based upon the number of outstanding shares of Casella common stock and KTI
common stock as of October 1, 1999, KTI shareholders immediately prior to the
merger are expected to own approximately 30.88% of the outstanding shares of
Casella common stock immediately after the merger, or 31.24% on a fully diluted
basis assuming the exercise of all KTI and Casella options, warrants and
convertible notes. These shares of Casella common stock would represent in the
aggregate approximately 22.31% of the votes entitled to be cast by Casella
stockholders after the merger, including the outstanding shares of Casella
Class B common stock, or 23.61% on a fully diluted basis assuming the exercise
of all KTI and Casella options, warrants and convertible notes.

OUR REASONS FOR THE MERGER (PAGES 32 THROUGH 37)

    We believe that the merger represents a highly favorable strategic
opportunity for Casella and KTI, two companies with complementary business
operations and geographical presence. The Casella board and the KTI board have
identified a number of potential benefits of the merger which they believe will
contribute to the success of the combined company, including:

    - complementary operations;

    - operational efficiencies of the combined company;

    - growth opportunities;

    - compatible strategies;

    - expected profitability;

    - larger critical mass; and

    - increased liquidity of the common stock of the combined company.

APPRAISAL RIGHTS (PAGES 49 AND 50)

    KTI shareholders who vote against the merger and who make the specified
written filing with KTI prior to the KTI shareholders meeting are entitled under
New Jersey law to seek an appraisal of the fair value of their shares and to be
paid cash for their shares. If a KTI shareholder does not follow the proper
procedures in exercising these appraisal rights or if a KTI shareholder
withdraws his demand for appraisal with KTI's consent, his KTI shares will be
converted into shares of Casella Class A common stock in accordance with the
merger agreement. We have attached a copy of the dissenters' rights statute as
Annex C to this proxy statement/prospectus, which you should be sure to read.

    Under Delaware law, Casella stockholders are not entitled to an appraisal of
the value of their shares in connection with the merger.

RECOMMENDATIONS OF THE CASELLA BOARD AND THE KTI BOARD RELATING TO THE MERGER
  (PAGES 20 AND 23)

    The Casella board recommends voting "FOR" the issuance of Casella Class A
common stock pursuant to the merger agreement. The KTI board recommends voting
"FOR" the approval of the merger agreement.

DIRECTORS AND EXECUTIVE OFFICERS OF CASELLA AFTER THE MERGER (PAGES 44 THROUGH
  46)

    The Casella board immediately after the merger will consist of the following
9 people: John W. Casella, Douglas R. Casella, James W. Bohlig, John F. Chapple
III and Gregory B. Peters, all of whom are currently directors of Casella, and
Ross Pirasteh, Martin J. Sergi, George J. Mitchell and Wilbur L.

                                       2
<PAGE>
Ross, Jr., all of whom are currently directors of KTI. In addition, two
additional directors may be designated by John W. Casella.

    After the merger, Casella's executive officers will include the following:

    - Ross Pirasteh, currently chairman of the KTI board, will serve as chairman
      of the Casella board;

    - John W. Casella, currently chairman, president and chief executive officer
      of Casella, will continue as president and chief executive officer;

    - James W. Bohlig, currently senior vice president and chief operating
      officer of Casella, will continue as senior vice president and chief
      operating officer;

    - Martin J. Sergi, currently president of KTI, will serve as executive vice
      president--business development; and

    - Jerry S. Cifor, currently senior vice president and chief financial
      officer of Casella, will continue as senior vice president and chief
      financial officer.

INTERESTS OF EXECUTIVE OFFICERS AND DIRECTORS OF CASELLA AND KTI IN THE MERGER
  (PAGES 43 AND 44)

    In connection with the merger, Casella will enter into employment agreements
with each of Messrs. Pirasteh, Casella, Bohlig, Sergi and Cifor. These
employment agreements are summarized in this proxy statement/prospectus.

    In connection with the merger, Paul Garrett, vice chairman of the KTI board,
will receive a payment of approximately $1.2 million in connection with his
existing employment agreement with KTI, which will be terminated.

OPINION OF KTI FINANCIAL ADVISOR (PAGES 37 THROUGH 43)

    On September 15, 1999, CIBC World Markets delivered an oral opinion, which
opinion was subsequently confirmed by delivery of a written opinion dated
September 15, 1999, to the KTI board as to the fairness, from a financial point
of view, of the exchange ratio to the holders of KTI common stock. On
September 23, 1999, after being advised that the merger is anticipated to be
accounted for as a purchase rather than as a pooling-of-interests transaction,
CIBC World Markets reaffirmed the conclusions of its written opinion dated
September 15, 1999. We have attached a copy of the full text of the written
opinion as Annex B-1 and a copy of the September 23, 1999 letter as Annex B-2 to
this proxy statement/prospectus. We urge you to read the opinion and the letter
in their entirety. THE OPINION IS DIRECTED TO THE KTI BOARD AND IS NOT A
RECOMMENDATION TO YOU AS TO HOW YOU SHOULD VOTE ON ANY MATTER RELATING TO THE
MERGER.

CONDITIONS TO BE SATISFIED BEFORE THE MERGER WILL OCCUR (PAGES 54 AND 55)

    Our obligations to complete the merger are subject to the satisfaction or
waiver of several conditions, including the following:

    - Casella stockholders must approve the issuance of shares to KTI
      shareholders;

    - KTI shareholders must approve the merger agreement;

    - there must not be any court order which effectively prohibits the merger;

    - each of Messrs. Pirasteh, John Casella, Bohlig, Sergi, Cifor and Garrett
      must have entered into lock-up agreements pursuant to which they agree not
      to sell their shares of Casella common stock for a period of 365 days
      after the merger;

                                       3
<PAGE>
    - the shares of Casella Class A common stock to be issued in the merger and
      upon the exercise of KTI options, warrants and convertible notes must be
      authorized for listing on the Nasdaq National Market; and

    - each company's representations and warranties contained in the merger
      agreement must be materially true and correct, and each company must have
      performed all of its material obligations under the merger agreement.

    The companies will recirculate revised proxy materials and resolicit proxies
if there are any material changes in the terms of the merger, including changes
that result from waivers of these conditions.

WHO CAN TERMINATE THE MERGER AGREEMENT; FEES AND EXPENSES (PAGES 55 THROUGH 57)

    The companies can agree to terminate the merger agreement without completing
the merger, and either company can terminate the merger agreement if any of the
following occur:

    - the merger is not completed by December 15, 1999;

    - a court or other governmental authority permanently prohibits the merger;

    - KTI shareholders do not approve the merger agreement or Casella
      stockholders do not approve the issuance of shares to KTI shareholders; or

    - the other company materially breaches the merger agreement and the breach
      is not cured within 30 days.

    In addition, Casella can terminate the merger agreement without completing
the merger if the KTI board:

    - changes its recommendation of the merger;

    - does not reconfirm its recommendation of the merger after receipt of a
      competing bid;

    - recommends a competing transaction to KTI shareholders;

    - recommends that KTI shareholders accept a tender offer or exchange offer
      for 25% or more of KTI's outstanding capital stock; or

    - fails to call and hold the KTI shareholders meeting by December 15, 1999.

    If the merger is completed, Casella will pay all fees and expenses incurred
in connection with the merger. If the merger agreement is terminated before the
merger takes place, either company may be required to reimburse the other party
for expenses of up to $3.0 million. In addition, if the merger agreement is
terminated before the merger takes place, KTI may be required to pay a
termination fee of $10.0 million to Casella.

THE VOTES REQUIRED AT THE STOCKHOLDERS MEETINGS TO APPROVE THE PROPOSALS (PAGES
  20 THROUGH 24)

    CASELLA.  A majority of the votes cast at the Casella annual meeting by the
holders of shares of Casella Class A common stock and Casella Class B common
stock, voting together as a class, is required to approve the issuance of shares
to KTI shareholders, to amend the Casella stock plans and to ratify the
selection of Casella's independent auditors for the current fiscal year. A
plurality of the votes cast by the holders of shares of Casella Class A common
stock and Casella Class B common stock, voting together as a class, is required
for the election of directors other than the Class A director. A plurality of
the votes cast by the holders of shares of Casella Class A common stock is
required for the election of the Class A director.

                                       4
<PAGE>
    The executive officers and directors (and a former director) of Casella have
agreed to vote all of their shares in favor of the proposal to issue shares to
KTI shareholders pursuant to the merger agreement and will be able to approve
the proposal without any other stockholder voting. Each share of Casella
Class A common stock will be entitled to one vote on each matter to be voted
upon at the Casella annual meeting, and each share of Casella Class B common
stock will be entitled to ten votes on each matter to be voted upon at the
Casella annual meeting other than the election of the Class A director.

    KTI.  The affirmative vote of a majority of the shares of KTI common stock
represented and voting at the KTI shareholders meeting is required to approve
the merger agreement. Directors and executive officers of KTI representing
approximately 16.7% of the shares of KTI common stock entitled to vote at the
shareholders meeting as of KTI's record date have agreed to vote all of their
shares in favor of the approval of the merger agreement.

THE RIGHTS OF KTI SHAREHOLDERS WILL CHANGE AS A RESULT OF THE MERGER (PAGES 147
  THROUGH 152)

    Currently, the rights of KTI shareholders are governed by New Jersey law and
KTI's charter and by-laws, and the rights of Casella stockholders are governed
by Delaware law and Casella's charter and by-laws. After the merger, KTI
shareholders will become stockholders of Casella and their rights will be
governed by Delaware law and Casella's charter and by-laws.

FEDERAL TAX CONSEQUENCES OF THE MERGER (PAGES 46 AND 47)

    We expect that for federal income tax purposes, KTI shareholders will
generally not recognize any gain or loss as a result of the exchange of shares
of KTI common stock for Casella Class A common stock. KTI shareholders will,
however, recognize income or gain in connection with any cash received instead
of fractional shares of Casella Class A common stock. A KTI shareholder's
holding period for the Casella Class A common stock received in the merger
generally will include the holding period of the KTI common stock exchanged in
the merger. The holding period is important because it determines how any gain
or loss should be treated for federal income tax purposes upon future sales of
Casella Class A common stock. Please remember that the tax consequences of the
merger may be different for you because of your particular tax status.
Accordingly, we urge you to consult with your tax advisor.

STOCK OPTION AGREEMENT (PAGES 57 AND 58)

    To induce Casella to enter into the merger agreement, KTI granted Casella an
option to purchase up to 2,769,331 shares of KTI common stock, representing
approximately 19.9% of KTI common stock at the date the merger agreement was
amended in May 1999, at a price of $10.40 per share. Casella may only exercise
this option under circumstances in which either Casella would be entitled to a
termination fee, or a third party makes an offer to acquire KTI.

ACCOUNTING TREATMENT (PAGE 48)

    We expect the merger to be accounted for using purchase accounting, with
Casella being deemed to have acquired KTI.

OTHER PROPOSALS TO BE CONSIDERED AT THE CASELLA ANNUAL MEETING (PAGES 153
  THROUGH 163)

    THE ELECTION OF CASELLA DIRECTORS.  Because this meeting is also Casella's
1999 annual meeting of stockholders, Casella stockholders are being asked to
vote for the election of James W. Bohlig and Gregory B. Peters as directors of
Casella, to serve for a term expiring in 2002. Both of Messrs. Bohlig

                                       5
<PAGE>
and Peters are currently directors of Casella. The Casella board recommends
voting "FOR" the election of these nominees.

    THE PROPOSAL TO RATIFY THE SELECTION OF ARTHUR ANDERSEN LLP AS CASELLA'S
AUDITORS.  Casella stockholders are being asked to ratify the selection of
Arthur Andersen LLP as Casella's independent auditors for the fiscal year ending
April 30, 2000. The Casella board recommends voting "FOR" this proposal.

    THE PROPOSALS TO AMEND THE CASELLA STOCK PLANS.  The Casella board has
approved amendments to its Amended and Restated 1997 Stock Incentive Plan, 1997
Non-Employee Director Stock Option Plan and Amended and Restated 1997 Employee
Stock Purchase Plan. These amendments would increase the number of shares of
Casella Class A common stock issuable under the plans and, with respect to the
1997 Non-Employee Director Stock Option Plan, increase the number of stock
options issuable to non-employee directors upon initial election to the Casella
board and at each annual meeting of stockholders. After considering the increase
in the number of Casella employees and directors as a result of the merger, the
Casella board believes that these amendments are necessary to ensure that an
adequate number of shares are available for grant to the eligible participants
under the plans, and recommends voting "FOR" the amendments to the Casella stock
plans. We have attached a copy of each of these plans as Annexes D-1, D-2 and
D-3 to this proxy statement/prospectus, which you should be sure to read.

                SUMMARY UNAUDITED PRO FORMA COMBINED INFORMATION

    The following unaudited pro forma combined financial information gives
effect to the merger under the purchase method of accounting. This pro forma
information is presented for illustrative purposes only. The pro forma
adjustments are based upon available information and certain assumptions that
management believes are reasonable. The pro forma combined financial information
does not purport to represent what the results of operations or financial
position of Casella would actually have been if the merger had in fact occurred
on such dates, nor does it purport to project the results of operations or
financial position of Casella for any future period or as of any date.
Additionally, no pro forma adjustments have been made to reflect potential
effects of (a) the efficiencies that may be obtained by combining the operations
of Casella and KTI or (b) the costs of restructuring, integrating or
consolidating the operations of Casella and KTI, except as disclosed in
Note 4(g). Under the purchase method of accounting, tangible and identifiable
intangible assets acquired and liabilities assumed are recorded at their
estimated fair values. The excess of the purchase price, including estimated
fees and expenses related to the merger, over the fair value of tangible net
assets acquired has preliminarily been allocated to goodwill and is being
amortized over an estimated blended life of 30 years. The estimated fair values
and useful lives of assets acquired and liabilities assumed are based on a
preliminary valuation and are subject to final valuation adjustments.

    Casella's and KTI's fiscal years end on different dates. Accordingly, to
prepare the pro forma combined financial statements:

    - The unaudited pro forma combined condensed balance sheet information as of
      July 31, 1999 was prepared by combining the balance sheet at July 31, 1999
      for Casella, with certain adjustments, with the balance sheet at June 30,
      1999 for KTI, giving effect to the merger as though it had been completed
      on July 31, 1999;

    - The unaudited pro forma combined condensed statement of operations for the
      three months ended July 31, 1999 was prepared by combining Casella's
      statement of operations for the three months ended July 31, 1999, with
      certain adjustments, with KTI's statement of operations for the three
      months ended June 30, 1999, giving effect to the merger as if it had
      occurred on May 1, 1998; and

    - The unaudited pro forma combined condensed statement of operations for the
      year ended April 30, 1999 was prepared by combining Casella's statements
      of operations for the year ended April 30, 1999, with certain adjustments,
      with KTI's statements of operations for the twelve months ended March 31,
      1999, as adjusted for an acquisition and the sale of substantially all
      assets of a business, giving effect to the merger as if it had occurred on
      May 1, 1998.

    For a description of the adjustments made in connection with the preparation
of the unaudited pro forma information, see "Unaudited Pro Forma Combined
Condensed Financial Information" beginning on page 132. For a description of the
adjustments made to KTI's historical financial information to adjust for certain
acquisitions, see "KTI Unaudited Adjusted Historical Statement of Operations"
beginning on page 138.

    The summary unaudited pro forma information is derived from the unaudited
pro forma financial information and related notes included elsewhere in this
proxy statement/prospectus, which you should read in its entirety.

(1) Adjusted EBITDA is defined as operating income less minority interest plus
    depreciation and amortization and loss on impairment of long-lived assets.
    Adjusted EBITDA does not represent, and should not be considered as, an
    alternative to net income or cash flows from operating activities, each as
    determined in accordance with generally accepted accounting principles
    (GAAP). Moreover, Adjusted EBITDA does not necessarily indicate whether cash
    flow will be sufficient to meet working capital, capital expenditures or
    other requirements, or to react to changes in our industry or to the economy
    generally. We believe that Adjusted EBITDA is a measure commonly used by
    lenders and certain investors to evaluate a company's performance in the
    solid waste industry. We also believe that Adjusted EBITDA data may help you
    to understand our performance because such data may reflect our ability to
    generate cash flows, which is an indicator of our ability to satisfy our
    debt service, capital expenditure and working capital requirements. Since
    all companies and analysts do not calculate Adjusted EBITDA in the same
    fashion, the Adjusted EBITDA measures presented by us may not be comparable
    to similarly titled measures reported by other companies. Therefore, in
    evaluating Adjusted EBITDA data, investors should consider, among other
    factors: the non-GAAP nature of Adjusted EBITDA data; actual cash flows; the
    actual availability of funds for debt service, capital expenditures and
    working capital; and the

                                       8

    comparability of our Adjusted EBITDA data to similarly-titled measures
    reported by other companies. For more information about cash flows, see the
    consolidated statements of cash flows in the consolidated financial
    statements that we have included in this proxy statement/prospectus.

                                  RISK FACTORS

    YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS, IN ADDITION TO THE
OTHER INFORMATION CONTAINED IN THIS PROXY STATEMENT/PROSPECTUS, IN DETERMINING
HOW TO VOTE AT YOUR STOCKHOLDERS MEETING. REFERENCES TO "WE" OR "US" IN THESE
RISK FACTORS MEANS THE COMBINED COMPANY FOLLOWING THE MERGER.

RISKS RELATING TO THE MERGER

   BECAUSE THE EXCHANGE RATIO IS FIXED, KTI AND CASELLA STOCKHOLDERS ARE EXPOSED
   TO THE RISK THAT THE MARKET PRICE OF THE OTHER COMPANY'S STOCK WILL DROP

    The fixed exchange ratio may not reflect the market value of Casella or KTI
common stock at the time the merger takes place, and KTI shareholders may
receive Casella Class A common stock with a market value greater than or below
the value of their KTI common stock. KTI shareholders will receive 0.51 of a
share of Casella Class A common stock in exchange for each share of KTI common
stock that they own. The market value of Casella Class A common stock and/or KTI
common stock at the closing of the merger may vary significantly from the price
as of the date the exchange ratio was fixed, the date of this proxy
statement/prospectus or the date on which stockholders vote on the merger. These
variations may be due to, among other factors:

    - market perception of the operational efficiencies and cost savings
      expected to be achieved by the merger;

    - changes in the business, operations or prospects of Casella and/or KTI;

    - market assessments of the likelihood that the merger will be consummated
      and its timing; and

    - general market and economic conditions.

    OUR EARNINGS COULD SUFFER IF WE DO NOT REALIZE THE OPERATIONAL EFFICIENCIES
    WE ANTICIPATE FROM THE MERGER

    Our inability to successfully or timely integrate the operations of the two
companies could have a material adverse effect on our business and operating
results. The managements of Casella and KTI have publicly announced that they
expect annualized operational efficiencies of approximately $8.2 million, plus
annualized interest savings of approximately $800,000, to be realized from the
merger. Integrating the operations and management of the two companies will be a
detailed, time-consuming process. The combined company's management team will
need to address the issues related to the management of a large number of
employees located at geographically dispersed facilities, as well as issues
related to doing business in Canada, including compliance with a variety of
environmental and other laws and regulatory requirements. These issues could
place a significant strain on our management and our operating, financial and
other resources, and we cannot assure you that the merger will result in the
anticipated operational efficiencies. Moreover, the dedication of management
resources to the integration of Casella and KTI may temporarily distract
management's attention from our day-to-day business, including the ongoing
acquisition program.

    CASELLA'S ABILITY TO MANAGE THE OPERATIONS ACQUIRED FROM KTI MAY BE
    ADVERSELY AFFECTED IF KTI'S MANAGEMENT DOES NOT REMAIN IN PLACE

    If key members of KTI's management were to terminate their employment with
KTI, or with the combined company following the merger, Casella's ability to
manage and integrate KTI's business and workforce would be harmed and Casella's
operations could be disrupted. The integration of Casella's and KTI's operations
will require substantial attention from Casella's management, and we will rely
on KTI's management for the initial successful operation of these assets. We
will be dependent on our management to run the combined company's business,
which will include operations not currently

                                       11
<PAGE>
conducted by Casella, and with respect to which Casella management has limited
experience, including waste-to-energy operations and the manufacturing of
finished products from recyclables.

    WE WILL DEFAULT UNDER OUR CREDIT FACILITY IF WE DO NOT OBTAIN A REPLACEMENT
    CREDIT FACILITY WITHIN THE EARLIER OF 30 DAYS FOLLOWING THE CLOSING OF THE
    MERGER OR NOVEMBER 30, 1999

    If we do not obtain a new revolving credit facility to replace Casella's
existing credit agreement within the earlier of 30 days following the closing of
the merger or November 30, 1999, we will be in default under Casella's existing
credit facility. At September 1, 1999, an aggregate of $96.9 million was
outstanding under this credit facility, which we will have to repay immediately
if we are in default. We do not have sufficient funds to repay this credit
facility if it were to be called for immediate repayment. Casella is currently
in negotiations with a number of banks, including BankBoston, N.A., which is the
lead bank under its existing credit facility, for a new credit facility. We
cannot assure you that we will be able to obtain a credit facility on terms
favorable to us, if at all. In the event we are unable to obtain a credit
facility on favorable terms, our acquisition program would be significantly
limited, and, if we were required to repay the existing credit facility
immediately as a result of a default, our business, results of operations and
financial condition would be materially adversely affected, including as a
result of the foreclosure by the banks of the assets held by them as security
for the credit facility.

    OUR ABILITY TO BORROW AFTER THE MERGER MAY BE ADVERSELY AFFECTED BY OUR
  INCREASED LEVERAGE

    The combined company's financial position will be more leveraged than
Casella's current financial position. Before the merger, Casella's debt to
capitalization ratio was 32.1% compared to KTI's 64.6%. Immediately upon the
closing of the merger, the combined company's debt to capitalization ratio is
expected to be approximately 55%. Although Casella has not yet negotiated the
terms of the agreement relating to a new credit facility, that agreement may
contain financial or other covenants that may, among other things, limit the
combined company's ability to incur additional indebtedness, and thereby limit
the company's ongoing acquisition program.

RISKS RELATING TO THE WASTE MANAGEMENT INDUSTRY OR PARTICULAR TO CASELLA OR KTI

    OUR GROWTH RATE MAY BE ADVERSELY AFFECTED IF WE ARE NOT ABLE TO CONTINUE TO
    IMPLEMENT OUR ACQUISITION STRATEGY

    Our failure to implement successfully our acquisition strategy would limit
our growth potential. We may not be able to implement our acquisition strategy,
on which our future growth is substantially based, due to the consolidation and
integration activity in the solid waste industry in recent years, as well as the
difficulties and expenses relating to the development and permitting of solid
waste landfills and transfer stations. These factors may result in fewer
acquisition opportunities for us as well as less advantageous acquisition terms,
including increased purchase prices. In addition, it may be difficult initially
to integrate the operations of any acquired businesses with the newly combined
company's business.

    We also believe that a significant factor in our ability to close
acquisitions will be the attractiveness of Casella Class A common stock as
consideration for potential acquisition candidates. This attractiveness may, in
large part, be dependent upon the relative market price and capital appreciation
prospects of Casella Class A common stock compared to the equity securities of
our competitors. If the market price of Casella Class A common stock were to
decline, our acquisition program could be materially adversely affected.

                                       12
<PAGE>
    ENVIRONMENTAL REGULATIONS COULD SUBJECT US TO FINES, PENALTIES AND
    LIMITATIONS ON OUR ABILITY TO EXPAND

    The combined business will be subject to potential liability and
restrictions under environmental laws. The waste-to-energy and manufacturing
facilities are subject to regulations limiting discharges of pollution into the
air and water, and the solid waste operations are subject to a wide range of
federal, state and, in some cases, local environmental and land use
restrictions. If we are not able to comply with the requirements that apply to a
particular facility, we could be subject to fines and penalties, and we may be
required to spend large amounts to bring an operation into compliance or to
temporarily or permanently stop an operation that is not permitted under the
law. Those costs or actions could have a material adverse effect upon our
business, financial condition and results of operations.

    Environmental and land use laws also can have an impact on whether our
operations can expand and, in the case of our solid waste operations, may
dictate those geographic areas from which we must, or, from which we may not,
accept waste. The waste management industry has been and likely will continue to
be subject to regulation, as well as to attempts to regulate the industry
through new legislation. Those regulations and laws also may limit the overall
size and daily waste volume that may be accepted by a solid waste operation. If
we are not able to expand or otherwise operate one or more of our facilities
profitably because of limits imposed under environmental laws, we may be
required to increase our utilization of disposal facilities owned by third
parties, and if so, our business, financial condition and results of operation
could suffer a material adverse effect.

    Both Casella and KTI have grown through acquisitions, and both businesses
have tried to evaluate and address environmental risks and liabilities presented
by newly acquired businesses as they have identified them. It is possible that
some liabilities, including ones that may exist only because of the past
operations of an acquired business, may prove to be more difficult or costly to
address than we anticipate. It is also possible that government officials
responsible for enforcing environmental laws may believe an issue is more
serious than we would expect, or that we will fail to identify or fully
appreciate a historic liability before we become legally responsible to address
it. Some of the legal sanctions to which we could become subject could cause us
to lose a needed permit, or prevent us from or delay us in obtaining or renewing
permits to operate our facilities. The number, size and nature of those
liabilities could have a material adverse effect on our business, financial
conditions and results of operations.

    OUR RESULTS OF OPERATIONS COULD BE ADVERSELY AFFECTED BY CHANGING PRICES OR
    MARKET REQUIREMENTS FOR RECYCLABLE MATERIALS

    Our results of operations may be materially adversely affected by changing
purchase or resale prices or market requirements for recyclable materials. Our
recycling business involves the purchase and sale of recyclable materials, some
of which are priced on a commodity basis. The resale and purchase prices of, and
market demand for, recyclable materials, particularly wastepaper, plastic and
ferrous and aluminum metals, can be volatile due to numerous factors beyond our
control. These changes have in the past contributed, and may continue to
contribute, to significant variability in our period-to-period results of
operations.

    Some of our subsidiaries involved in the recycling business use long-term
supply contracts with customers with floor price arrangements to minimize the
commodity risk for recyclable materials, particularly wastepaper and aluminum
metals. Under these contracts, our subsidiaries obtain a guaranteed minimum
floor price for the recyclable materials along with a commitment to receive
additional amounts if the current market price rises above the minimum price.
These contracts are generally with large domestic companies which use the
recyclable materials in their manufacturing processes. Any failure to continue
to secure long-term supply contracts with minimum price arrangements, or a
breach by customers of one or more of these contracts could reduce our recycling
revenues and have a material adverse effect on our business, financial condition
and results of operations.

                                       13
<PAGE>
    THE SEASONALITY OF OUR REVENUES COULD ADVERSELY IMPACT OUR FINANCIAL
    CONDITION

    Future seasonal fluctuations in our revenues could have a material adverse
effect on our business, financial condition and results of operations. Casella's
and KTI's revenues have historically been lower during the months of November
through March. This seasonality reflects the lower volume of solid waste during
the late fall, winter and early spring months resulting primarily from:

    - the volume of solid waste relating to construction and demolition
      activities decreasing substantially during the winter months in the
      northeastern United States; and

    - decreased tourism in Vermont, Maine and eastern New York during the winter
      months, which tends to lower the volume of solid waste generated by
      commercial and restaurant customers, which is only partially offset by the
      winter ski industry.

    Since some of our operating and fixed costs remain constant throughout the
fiscal year, our operating income is seasonally impacted. In addition,
particularly harsh weather conditions could result in increased operating costs
for some of our operations.

    OUR BUSINESS IS GEOGRAPHICALLY CONCENTRATED AND IS THEREFORE SUBJECT TO
    REGIONAL ECONOMIC DOWNTURNS

    Our operations and customers are principally located in the eastern United
States. Therefore, our business, financial condition and results of operations
are susceptible to regional economic downturns and other regional factors,
including state regulations and severe weather conditions. In addition, as we
expand in our existing markets, opportunities for growth within these regions
will become more limited. The costs and time involved in permitting and the
scarcity of available landfills will make it difficult for us to expand
vertically in these markets. We cannot assure you that we will complete enough
acquisitions in other markets to lessen our regional geographic concentration.

    WE MAY NOT BE ABLE TO EFFECTIVELY COMPETE IN THE HIGHLY COMPETITIVE SOLID
    WASTE SERVICES INDUSTRY

    The solid waste services industry is highly competitive, is undergoing a
period of increasingly rapid consolidation, and requires substantial labor and
capital resources. Some of the markets in which we compete or will likely
compete are served by one or more of the large national or multinational solid
waste companies, as well as numerous regional and local solid waste companies.
Intense competition exists not only to provide services to customers but also to
acquire other businesses within each market. Some of our competitors have
significantly greater financial and other resources than us. From time to time,
competitors may reduce the price of their services in an effort to expand market
share or to win a competitively bid municipal contract. These practices may
either require us to reduce the pricing of our services or result in our loss of
business. As is generally the case in the industry, municipal contracts are
subject to periodic competitive bidding. There can be no assurance that we will
be the successful bidder to obtain or retain these contracts. If we are unable
to compete with larger and better capitalized companies, or to replace municipal
contracts lost through the competitive bidding process with comparable contracts
or other revenue sources within a reasonable time period, our business,
financial condition and results of operations could be materially adversely
affected.

    In our solid waste disposal markets, we also compete with operators of
alternative disposal and recycling facilities and with counties, municipalities
and solid waste districts that maintain their own waste collection, recycling
and disposal operations. These entities may have financial advantages because
user fees or similar charges, tax revenues and tax-exempt financing may be more
available to them than to us.

    Our insulation manufacturing operations compete primarily with large
manufacturers of fiberglass insulation, including Owens Corning, Certainteed and
Johns Mansville Corp. and with Louisiana Pacific Corporation, a manufacturer of
cellulose insulation. These companies have substantially greater resources than
Casella which they could use for product development, marketing or other
purposes to the detriment of Casella.

    KTI ENERGY OF VIRGINIA, INC. SELLS ITS ENTIRE OUTPUT TO A FEW CUSTOMERS AND
    LACKS THE CAPACITY TO MEET ALL OF ITS COMMITMENTS

    KTI Energy of Virginia, Inc., a subsidiary of KTI, operates three steam
generating plants, one of which produces steam for a facility owned by E. I. du
Pont de Nemours and Company under a five-year contract expiring on May 30, 2003.
Du Pont has significantly reduced operations at this facility, and has the
option to terminate the contract upon payment of a termination fee. The second
plant produces steam for an industrial park. Approximately 85% of the steam
produced by the plant is purchased by one customer under a contract that may not
be terminated by the customer except for cause, and the balance is sold to ten
customers under contracts which provide that KTI Energy of Virginia may elect
not to supply steam. Currently, maximum contracted capacity for all customers
for steam exceeds the maximum rated capacity that may be produced by this plant.
Actual demand, however, has not exceeded the maximum rated capacity. If actual
demand grows, the plant may need to install equipment to respond to peak
demands, as well as equipment which may be necessary to allow the plant to meet
stricter air quality standards, which may be adopted in the near future. The
cost of this air quality equipment, not including the equipment necessary to
respond to peak demands, is expected to be approximately $1.2 million. A third
steam generating plant operated by a subsidiary of KTI Energy of Virginia sells
all of its output to one customer under a contract that provides the customer
the option to terminate the contract upon payment of a termination fee of
approximately $250,000. The termination of the contract with Du Pont or any of
the significant customers who purchase steam from KTI Energy of Virginia or its
subsidiary could have a material adverse effect on our business, financial
condition and results of operations.

    OUR RESULTS OF OPERATIONS AND FINANCIAL CONDITION MAY BE NEGATIVELY AFFECTED
    IF WE INADEQUATELY ACCRUE FOR CLOSURE AND POST-CLOSURE COSTS

    We have material financial obligations relating to closure and post-closure
costs of our existing landfills and will have material financial obligations
with respect to any disposal facilities which we may own or operate in the
future. In addition to the landfills Casella currently operates, Casella owns
four unlined landfills which are not currently in operation. Casella has
provided and will in the future provide accruals for financial obligations
relating to closure and post-closure costs of its owned or operated landfills,
generally for a term of 30 years after final closure of a landfill. We cannot
assure you that our financial obligations for closure or post-closure costs will
not exceed the amount accrued and reserved or amounts otherwise receivable
pursuant to trust funds established for this purpose. Such a circumstance could
result in unanticipated charges and have a material adverse effect on our
business, financial condition and results of operations.

    WE COULD BE PRECLUDED FROM ENTERING INTO CONTRACTS OR OBTAINING PERMITS IF
    WE ARE UNABLE TO OBTAIN THIRD PARTY FINANCIAL ASSURANCE TO SECURE OUR
    CONTRACTUAL OBLIGATIONS

    Municipal solid waste collection and recycling contracts, obligations
associated with landfill closure and the operation and closure of
waste-to-energy facilities may require performance or surety bonds, letters of
credit or other means of financial assurance to secure our contractual
performance. If we are unable to obtain the necessary financial assurance in
sufficient amounts or at acceptable rates, we could be precluded from entering
into additional municipal solid waste collection contracts or from obtaining or
retaining landfill operating permits. Any future difficulty in obtaining
insurance could also impair our ability to secure future contracts conditioned
upon the contractor having adequate insurance coverage. Accordingly, our failure
to obtain financial assurance bonds, letters of credit or other means of
financial assurance or to maintain adequate insurance could have a material
adverse effect on our business, financial condition and results of operations.

    WE MAY BE REQUIRED TO WRITE-OFF CAPITALIZED CHARGES IN THE FUTURE, WHICH
    COULD ADVERSELY AFFECT OUR EARNINGS

    Any charge against earnings could have a material adverse effect on our
earnings and the market price of Casella Class A common stock. In accordance
with generally accepted accounting principles, we capitalize certain
expenditures and advances relating to our acquisitions, pending acquisitions,
landfills and development projects. From time to time in future periods, we may
be required to incur a charge against earnings in an amount equal to any
unamortized capitalized expenditures and advances, net of any portion thereof
that we estimate will be recoverable, through sale or otherwise, relating to
(a) any operation that is permanently shut down or has not generated or is not

    THE CASELLA CLASS B COMMON STOCK HAS TEN VOTES PER SHARE AND IS HELD
    EXCLUSIVELY BY JOHN W. CASELLA AND DOUGLAS R. CASELLA

    The holders of Casella Class B common stock are entitled to ten votes per
share and the holders of Casella Class A common stock are entitled to one vote
per share. At September 1, 1999, an aggregate of 988,200 shares of Casella
Class B common stock, representing 9,882,000 votes, were outstanding, all of
which were beneficially owned by John W. Casella, the president and chief
executive officer of Casella and chairman of the Casella board, or by his
brother, Douglas R. Casella, the vice chairman of the Casella board. Based on
the number of shares of Casella common stock and KTI common stock outstanding at
September 1, 1999, the shares of Casella Class A common stock and Class B common
stock held by John W. Casella and Douglas R. Casella will represent
approximately 35.4% of the aggregate voting power of Casella immediately
following the merger. Consequently, John W. Casella and Douglas R. Casella will
be able to substantially influence all matters for stockholder consideration.

                           COMPARATIVE PER SHARE DATA

    This table summarizes information about our historical basic and diluted
(loss) income per common share and book value per share. The table also presents
information on an unaudited pro forma combined basis after giving effect to the
merger using the purchase method of accounting for business combinations.

    Neither Casella nor KTI has paid cash dividends on its common stock.

    The historical financial information for Casella has been restated to
reflect the mergers with Corning Community Disposal and Resource Waste Systems
consummated on June 4, 1999 and July 1, 1999, respectively, accounted for using
the pooling of interests method of accounting.

    The pro forma financial information is not necessarily indicative of what
our results of operations or financial position would have been if the merger
actually occurred on the dates indicated, nor are they necessarily indicative of
the future operating results or financial position of the combined company. We
have not included pro forma adjustments that reflect potential effects of
(a) the efficiencies that may be obtained by combining the operations of Casella
and KTI, or (b) the costs of restructuring, integrating or consolidating the
operations of Casella and KTI, except as disclosed in note 4(g).

    You should read this table in conjunction with the selected historical
financial information of Casella and KTI and the unaudited pro forma combined
financial information included elsewhere in this proxy statement/prospectus.

Class A common stock was $15.50 per share and the last reported sale price of

    Because the market prices of Casella Class A common stock and KTI common
stock are subject to fluctuation, the market value of the shares of Casella
Class A common stock that holders of KTI common stock will receive in the
merger, and the market value of the KTI common stock exchanged in the merger,
may increase or decrease prior to or after the merger.

    WE URGE YOU TO OBTAIN CURRENT MARKET QUOTATIONS FOR THE CASELLA CLASS A
COMMON STOCK AND THE KTI COMMON STOCK.

DIVIDENDS

    Neither Casella nor KTI has ever paid cash dividends on its common stock.
The decision whether to pay any dividends in the future on Casella common stock
will be made by the Casella board from time to time in the exercise of its
business judgment. The Casella board does not currently intend to pay cash
dividends in the foreseeable future. Casella's revolving credit facility
restricts its ability to pay dividends.

      shares to 5,328,135 shares;

    - a proposal to approve amendments to Casella's 1997 Non-Employee Director
      Stock Option Plan increasing the aggregate number of shares of Casella
      Class A common stock that may be issued under the plan from 50,000 shares

    - to transact such other business as may properly be brought before the

    RECOMMENDATION OF THE CASELLA BOARD

    The Casella board has unanimously approved the merger agreement, and each of
the proposals to be presented at the annual meeting, and recommends that you
vote "FOR" approval of each of these proposals.

    STOCKHOLDERS ENTITLED TO VOTE; THE VOTE REQUIRED IS ASSURED

    The merger cannot be completed without Casella stockholder approval of the
proposal to issue shares in exchange for KTI shares. The directors and executive
officers of Casella, voting together, represent sufficient votes to approve the
proposals without any other Casella stockholder voting on the proposals. Each
director and executive officer (and a former director) of Casella has agreed to
vote all of his shares in favor of the proposal to issue shares to KTI
shareholders pursuant to the merger agreement. Accordingly, a vote in favor of
the proposal to issue shares to KTI shareholders pursuant to the merger
agreement is assured.

record, outstanding and entitled to vote.

    Each share of Casella Class A common stock will have one vote for each
matter properly submitted to the Casella annual meeting, and each share of
Casella Class B common stock will have ten votes for each matter properly
submitted to the Casella annual meeting other than the election of the Class A
director.

    The approval of the proposals to issue shares to KTI shareholders pursuant
to the merger agreement, to amend the Casella stock plans and to ratify the
selection of Casella's independent auditors for the current fiscal year requires
a majority of the votes cast at the Casella annual meeting by the holders of
shares of Casella Class A common stock and Casella Class B common stock, voting
together as a class. The approval of the proposal to issue shares to KTI
shareholders pursuant to the merger agreement is required under the maintenance
requirements of The Nasdaq Stock Market, Inc. The approval of the proposal to
elect directors, other than the Class A director, requires a plurality of the
votes cast at the Casella annual meeting by the holders of shares of Casella
Class A common stock and Casella Class B common stock, voting together as a
class. A plurality of the votes cast at the Casella annual metting by the
holders of shares of Casella Class A common stock is required for the election
of the Class A director.

    As of October 15, 1999, the directors (and the former director who agreed to
vote in favor of the proposal to issue shares in exchange for KTI shares) and
executive officers of Casella and certain of their affiliates beneficially owned
16.82% of the outstanding shares of Casella common stock, representing
approximately 46.53% of the votes entitled to be cast at the Casella annual
meeting. These figures are calculated without counting shares which could be
acquired by exercising stock options because the shares underlying those options
cannot be voted at the annual meeting.

    The presence, in person or by proxy, of shares representing a majority of
the votes entitled to be cast at the Casella annual meeting by the holders of
Casella Class A common stock and Casella Class B common stock, voting together
as a class, is necessary to constitute a quorum other than for the election of
the Class A director. The presence, in person or by proxy, of shares
representing a majority of the votes entitled to be cast at the Casella annual
meeting by the holders of Casella Class A common stock is necessary to
constitute a quorum for the election of the Class A director.

    VOTING OF PROXIES

    All shares held by Casella stockholders who are entitled to vote and who are
represented at the Casella annual meeting by properly executed proxies received
prior to or at the annual meeting will be voted in accordance with the
instructions you indicate on the proxy card, unless you revoke the proxy prior
to the vote. If you send us a proxy card which does not instruct us how to vote,
your shares will be voted "FOR" approval of each of the proposals, and "FOR"
each nominee for election as a director, set forth in the notice of the meeting
to which this proxy statement/prospectus is attached.

    You may revoke any proxy that you give at any time before it is used to cast
your vote. To revoke a proxy, you must either:

    - file with the secretary of Casella, at or before the taking of the vote, a
      written notice of revocation bearing a later date than the proxy;

    - duly execute a later dated proxy relating to the same shares and deliver
      it to the secretary of Casella before the taking of the vote; or

                                       21
<PAGE>
    - attend the Casella annual meeting and vote in person. ATTENDANCE AT THE
      CASELLA ANNUAL MEETING, IF YOU DO NOT VOTE, WILL NOT BE SUFFICIENT TO
      REVOKE A PROXY.

    Any written notice of revocation or subsequent proxy should be sent to:

                                  Casella Waste Systems, Inc.
                                  25 Greens Hill Lane
                                  Rutland, Vermont 05701
                                  Attention: Secretary

    If you have indicated on your proxy that your shares should be voted "FOR"
approval of the matters presented to Casella stockholders at the Casella
meeting, the proxies will have discretion to vote your shares on any other
matters which are properly presented at the Casella annual meeting for
consideration, including a motion to adjourn the Casella meeting to another time
or place for the purpose of soliciting additional proxies, unless you withhold
your authorization for the proxies to use their discretion. To withhold
authorization, instruct us to vote "NO" on the proxy card. Casella is not aware
of any matters expected to be presented at its annual meeting other than the
proposals described in the notice of meeting.

    If a broker does not have discretionary voting authority to vote shares for
which it is the holder of record as to a particular matter at the Casella annual
meeting, the shares, although they will be counted in determining whether a
quorum is present, cannot be voted by the broker. Accordingly, these broker
non-votes and abstentions will have no effect on whether a proposal presented at
the Casella annual meeting is approved or not.

    SOLICITATION OF PROXIES

    The expenses of the solicitations for the Casella annual meeting, including
the cost of printing and distributing this proxy statement/prospectus and the
forms of proxy, will be paid by Casella. In addition to solicitation by mail,
proxies may be solicited by directors, officers and employees of Casella in
person or by telephone, telecopier or other means of communication. These
persons will not receive additional compensation for solicitation of proxies,
but may be reimbursed for reasonable out-of-pocket expenses in connection with
this solicitation. Arrangements will also be made by Casella with custodians,
nominees and fiduciaries for forwarding of proxy solicitation materials to the
beneficial owners of shares, and Casella will reimburse these persons for
reasonable expenses incurred in connection with this solicitation.

THE KTI SHAREHOLDERS MEETING

    WHEN AND WHERE THE SHAREHOLDERS MEETING WILL BE HELD

    This proxy statement/prospectus solicits, on behalf of the KTI board,
proxies to be voted at the KTI shareholders meeting to be held as follows, and
at any adjournment or postponement thereof:

                                  Wednesday, December 8, 1999
                                  10:00 a.m., local time
                                  KTI, Inc.
                                  7000 Boulevard East
                                  Guttenberg, New Jersey 07093

    MATTERS TO BE CONSIDERED AT THE KTI SHAREHOLDERS MEETING

    At the KTI shareholders meeting, KTI shareholders will consider and vote on:

    - the approval of the merger agreement; and

                                       22
<PAGE>
    - any other matters incidental to the approval of the merger agreement or to
      the conduct of the KTI shareholders meeting that may properly be brought
      before the KTI shareholders meeting or at any adjournment or postponement
      thereof.

    RECOMMENDATION OF THE KTI BOARD

    The KTI board has unanimously approved the merger agreement and recommends
that you vote "FOR" approval of the merger agreement. See "The Merger--Reasons
for the merger".

    SHAREHOLDERS ENTITLED TO VOTE; VOTE REQUIRED

    The merger cannot be completed without KTI shareholder approval. Directors
and executive officers of KTI representing in the aggregate approximately 16.7%
of the outstanding shares of KTI as of November 10, 1999 have agreed to vote all
the shares they beneficially own in favor of the proposal to approve the merger
agreement.

    The KTI board has fixed November 10, 1999 as the record date for
determination of KTI shareholders entitled to vote at the KTI shareholders
meeting. Only holders of record of KTI common stock at the close of business on
the record date will be entitled to receive notice of and to vote at the KTI
shareholders meeting. On the record date, there were 14,023,838 shares of KTI
common stock outstanding and entitled to vote at the KTI shareholders meeting,
which were held by approximately 240 holders of record.

    Each share of KTI common stock will have one vote for each matter properly
submitted to the KTI shareholders meeting. The affirmative vote of a majority of
the shares of KTI common stock represented and voting at the KTI shareholders
meeting is required in order to approve the merger agreement.

    The required vote of the KTI shareholders on the merger agreement is based
upon the number of shares which are actually voted, rather than the total number
of outstanding shares of KTI common stock. Thus, if you abstain from voting or
if you do not submit a proxy card and do not vote in person at the KTI
shareholders meeting, your action will have no effect. Also, any broker non-vote
will have no effect.

    As of the record date, the directors and executive officers of KTI
beneficially owned 2,336,052 shares of KTI common stock, representing
approximately 16.7% of the issued and outstanding shares of KTI common stock.
These figures are calculated without counting shares which could be acquired by
exercising stock options or warrants because the shares underlying those options
cannot be voted at the meeting.

    The presence, in person or by proxy, of a majority of the KTI common stock
issued and outstanding and entitled to be voted at the KTI shareholders meeting
is necessary to constitute a quorum.

    VOTING OF PROXIES

    If you properly execute a proxy card and send it to KTI in a timely manner,
your proxy will be voted in accordance with the instructions you indicate on the
proxy card, unless you revoke your proxy prior to the vote. If you send us a
proxy card which does not instruct us how to vote, your shares will be voted
"FOR" approval of the merger agreement.

    You may revoke any proxy that you give at any time before it is used to cast
your vote. Attendance at the KTI shareholders meeting will not be sufficient to
revoke your proxy. To revoke a proxy, you must either:

    - attend the KTI shareholders meeting and vote in person;

    - file a written notice of revocation with the KTI secretary; or

                                       23
<PAGE>
    - deliver a properly executed proxy with a later date to the KTI secretary.

    The KTI secretary will be in attendance at the KTI shareholders meeting and,
prior thereto, can be reached at the following address:

                                  KTI, Inc.
                                  7000 Boulevard East
                                  Guttenberg, New Jersey 07093
                                  Attention: Ross Pirasteh

    If you have indicated on your proxy that your shares should be voted "FOR"
approval of the matters presented to KTI shareholders at the meeting, the
persons named on the enclosed proxy card will have the discretion to vote on any
other matters which are properly presented at the KTI shareholders meeting,
including a motion to adjourn the meeting to another time or place for the
purpose of soliciting additional proxies, unless you specifically withhold that
authorization when you complete your proxy card. To withhold authorization,
instruct us to vote "NO" on the proxy card. KTI is not aware of any matters that
will come before the KTI shareholders meeting other than the vote on the merger.

    Votes cast by proxy or in person at the KTI shareholders meeting will be
tabulated by the election inspectors appointed for the meeting, who will
determine whether or not a quorum is present. Where proxies are marked as
abstentions, where shareholders appear in person but abstain from voting, or
where a broker indicates on a proxy that it does not have discretionary voting
authority regarding certain shares, those abstentions and broker non-votes will
be treated as shares that are present and entitled to vote for purposes of
determining the presence of a quorum.

KTI SHAREHOLDERS SHOULD NOT SEND ANY STOCK CERTIFICATES WITH THEIR PROXY CARDS.

    SOLICITATION OF PROXIES

    In addition to using the mails, the directors, officers and employees of KTI
may solicit proxies for the KTI shareholders meeting from shareholders in person
or by telephone. These directors, officers and employees will not be
specifically compensated for their services. KTI has retained D.F. King and Co.,
Inc., a proxy soliciting firm, to assist in soliciting proxies. D.F. King and
Co., Inc. will be paid a fee and reimbursed for certain out-of-pocket expenses,
in an aggregate amount of approximately $25,000. KTI will also make arrangements
with brokerage firms and other custodians, nominees and fiduciaries to send
proxy materials to their principals and will reimburse those parties for their
expenses in doing so. KTI will pay all costs of soliciting proxies for the KTI
shareholders meeting.

                                   THE MERGER

BACKGROUND OF THE MERGER

    Historically, Casella and KTI have had mutual customer/vendor relationships
in the state of Maine. As a result of this relationship, the management of both
companies were quite familiar with each other. On August 18, 1998, KTI entered
into a letter of intent to acquire Recovery Technology Inc., a Canadian company
which specializes in a cryogenic tire recycling process. As a result of that
contemplated acquisition, Ross Pirasteh, the chairman of the KTI board and
Martin J. Sergi, the president of KTI, began to consider the acquisition of
Casella's tire processing facility in Elliott, Maine. In early November, 1998,
Mr. Pirasteh called John W. Casella, the chairman of the board, chief executive
officer and president of Casella, to arrange meetings on November 10th and 11th
to discuss expanding the relationship of the two companies, including a purchase
of the tire processing facility and other strategic ventures.

    On November 10 and 11, 1998, John W. Casella and James W. Bohlig, the chief
operating officer and senior vice president of Casella, met at the New York
Hilton with Ross Pirasteh, Martin J. Sergi and Paul A. Garrett, vice chairman of
the KTI board. At that meeting, the participants discussed the possibility of a
strategic business combination between Casella and KTI as a means of creating
value for each company's stockholders. KTI indicated that it would be interested
in considering such a transaction if the exchange ratio reflected a premium over
its current stock price, which was below its 52-week high. The participants also
discussed, on a preliminary basis, certain significant terms of a potential
business combination, including among other things, the desired accounting and
tax treatment, the structure and composition of the combined company's
management and board of directors, and potential operating efficiencies. The
parties tentatively agreed in concept, subject to definitive documentation and
due diligence, to an exchange ratio whereby each share of KTI common stock would
be exchanged for one share of Casella Class A common stock.

    On November 12, 1998, Mr. Casella asked Donaldson, Lufkin & Jenrette
Securities Corporation to prepare an analysis of the transaction for purposes of
advising Casella's management team and board. Also, on or about November 16,
1998, Mr. Casella asked Goldman, Sachs & Co. to begin to analyze the transaction
for purposes of being in a position to render a fairness opinion to the Casella
board as to the proposed one-for-one exchange ratio.

    On November 16, 1998, the KTI board held a telephonic meeting to discuss the
terms of the proposed merger. In particular, the KTI board discussed the
exchange ratio and the feasibility of adjusting the exchange ratio based upon
fluctuations in the market price of KTI and Casella common stock. In addition,
the KTI board also discussed the structure of the Casella board and management
team after the merger and noted that after the merger no one person or group
would control the combined company. After discussing the accounting treatment of
the merger, the anticipated operational efficiencies, the combined company's
voting power and possible market reaction, the KTI board decided to pursue
further discussions with Casella.

    On November 18, 1998, the KTI board held another telephonic meeting to
discuss the current status of the proposed merger. The KTI board discussed the
status of the legal, environmental and financial due diligence review of Casella
and the accounting treatment of the merger. The KTI board also discussed the
possible timing of the signing of the merger agreement and the consummation of
the merger. At the meeting, the KTI board authorized KTI to retain Credit Suisse
First Boston Corporation and CIBC World Markets Corp. to act as financial
advisors to KTI in connection with the proposed merger.

    On November 19, 1998, Hale and Dorr LLP, Casella's legal advisors,
distributed the first draft of the proposed merger agreement. On November 23,
1998, Mr. Casella, Mr. Bohlig, Mr. Pirasteh and their respective legal advisors,
together with representatives of Donaldson, Lufkin & Jenrette and

                                       25
<PAGE>
Credit Suisse First Boston, met at the offices of KTI's legal advisors, in New
York City to negotiate provisions of the draft merger agreement.

    On December 2, 1998, at Casella's regularly scheduled board meeting,
Messrs. Casella and Bohlig updated the Casella board on the status of
negotiations with KTI. At that meeting, the Casella board reviewed a number of
documents relating to the proposed merger, including drafts of the merger
agreement and proposed employment agreements, due diligence memoranda, KTI's
filings with the Securities and Exchange Commission, the resolutions that would
need to be approved by the Casella board in connection with the merger and
financial models. Casella's legal advisors also advised the Casella board of
their fiduciary duties in considering the transaction.

    Between November 20, 1998 and December 9, 1998, representatives of
Donaldson, Lufkin & Jenrette, Goldman, Sachs, Credit Suisse First Boston and
CIBC World Markets, along with Casella's and KTI's legal advisors, consultants
and accountants, conducted due diligence investigations of the respective
companies.

    On December 10, 1998, Messrs. Casella and Bohlig updated the Casella board
as to the status of the merger negotiations. At the meeting, Messrs. Casella and
Bohlig informed the Casella board that, after further due diligence and
analysis, Goldman, Sachs had indicated to Casella that, based on their analysis
of KTI's projected results of operations, they did not believe that the
one-for-one exchange ratio was warranted.

    On December 11, 1998, Messrs. Casella, Bohlig and Cifor met with
representatives of Goldman, Sachs to provide them with further information on
the proposed merger and the basis for the one-for-one exchange ratio. In
addition, Messrs. Casella and Bohlig discussed with KTI management their
interest in proceeding with the merger at a reduced exchange ratio. At the time,
KTI was not receptive to the discussions. On December 15, 1998, a representative
of Goldman, Sachs again informed Mr. Casella that Goldman, Sachs did not believe
the one-for-one exchange ratio was warranted.

    During the balance of the week of December 14, 1998 and for the following
week, Donaldson, Lufkin & Jenrette conducted further due diligence and analysis.
On December 17, 1998, Messrs. Casella and Bohlig and representatives of
Donaldson, Lufkin & Jenrette met with Messrs. Pirasteh, Sergi and Garrett at
KTI's offices in Guttenberg, New Jersey. Mr. Casella indicated that Casella was
not prepared to proceed with a transaction with a one-for-one exchange ratio.
The parties discussed a proposal that the exchange ratio be modified. Based on
Donaldson, Lufkin & Jenrette's analysis, a level of approximately 0.90 shares of
Casella Class A common stock for every share of KTI common stock was proposed.

    Following that meeting, Casella, KTI and representatives of Donaldson,
Lufkin & Jenrette and Credit Suisse First Boston had numerous discussions by
phone and in person to negotiate aspects of the transaction, including the
exchange ratio. Casella, during that process, rejected a number of KTI proposals
ranging from 0.975 to 0.925.

    On January 6, 1999, Messrs. Casella and Bohlig updated the Casella board as
to the status of the merger negotiations in a telephone conference call meeting.

    On January 8, 1999 and 9, 1999, Messrs. Casella and Pirasteh and
representatives of Donaldson, Lufkin & Jenrette and Credit Suisse First Boston
had a number of telephone conversations, resulting in a tentative agreement,
subject to the approval of the parties' respective boards of directors and
appropriate fairness opinions, on a 0.91 exchange ratio. Messrs. Casella and
Pirasteh based their agreement on, among other factors, the historical financial
results of Casella and KTI, the projected operating results and financial
condition of the combined company and expected operational efficiencies
resulting from the transaction. Between January 9, 1999 through the signing of
the merger agreement, representatives of Casella and KTI and their respective
legal and financial advisors continued to discuss the terms of the merger
agreement and related documents, as well as accounting

                                       26
<PAGE>
and other transaction issues, and continued their financial, legal,
environmental and accounting due diligence investigations of the respective
companies.

    On January 11, 1999, the KTI board held a telephonic meeting to discuss the
revised terms of the merger agreement and the exchange ratio. In particular, the
KTI board reviewed the expenses and termination fee payable by KTI under the
merger agreement and reviewed the conditions to the consummation of the merger.
KTI's legal advisors advised the KTI board of its fiduciary duties in
considering the approval of the merger agreement. The KTI board reviewed the
provisions of the merger agreement limiting their ability to talk to competing
bidders, unless required to do so consistent with their fiduciary duties. The
agreements to be signed by the directors requiring them to vote in favor of the
merger agreement and not to sell their shares of KTI common stock were also
discussed. Copies of the revised draft of the merger agreement were sent to each
member of the KTI board in advance of the meeting the following day.

    On January 12, 1999, the Casella board met at the offices of Donaldson,
Lufkin & Jenrette to consider the approval of the merger agreement. Members of
Casella's management team and legal advisors also attended the meeting. At the
meeting, the board reviewed the proposed terms of the merger agreement,
Casella's legal, financial, environmental and accounting due diligence
investigations of KTI, the regulatory approvals that would be required to
consummate the merger, the potential effects of the merger, the potential impact
of not proceeding with the merger, the potential effects of the merger on the
combined company and the board's fiduciary duties. At the board meeting,
Donaldson, Lufkin & Jenrette delivered its written and oral opinion to the
Casella board that, as of such date, and based upon and subject to the
assumptions made, matters considered and limitations on the review undertaken
set forth in the Donaldson, Lufkin & Jenrette opinion, the 0.91-for-one exchange
ratio was fair to Casella and its stockholders from a financial point of view.
At the meeting, the Casella board unanimously approved the merger agreement and
the transactions contemplated thereby, declared the advisability of the merger
agreement, and unanimously recommended that the holders of Casella common stock
vote to approve the issuance of shares of Casella Class A common stock to KTI
shareholders in connection with the merger. Casella had requested a fairness
opinion from Donaldson, Lufkin & Jenrette because of their close involvement in
advising Casella as to all aspects of the transaction, particularly in
connection with the reduction of the exchange ratio. Casella had not requested
Goldman, Sachs to advise it in connection with the negotiations with KTI and
accordingly did not request Goldman, Sachs to deliver a fairness opinion as to
the 0.91-for-one exchange ratio.

    On January 12, 1999, the KTI board met at the offices of its legal advisors
in New York City to consider the approval of the merger. KTI's legal advisors
also attended the meeting and discussed the board's fiduciary duties to KTI
shareholders. At the meeting, the board reviewed the proposed terms of the
merger agreement, KTI's legal, financial, environmental and accounting due
diligence investigations of Casella, the regulatory approvals that would be
required to consummate the merger, the potential effects of the merger, the
potential effects of not proceeding with the merger, and the potential effects
of the merger on the combined company. At the board meeting, each of Credit
Suisse First Boston and CIBC World Markets presented their respective financial
analyses with respect to the 0.91-for-one exchange ratio and delivered separate
opinions to the KTI board that, as of that date and based upon and subject to
the matters stated in their respective opinions, the 0.91-for-one exchange ratio
was fair, from a financial point of view, to the holders of KTI common stock. At
the meeting, the KTI board unanimously approved the merger agreement and the
transactions contemplated thereby, and unanimously recommended that the holders
of KTI common stock vote to approve the merger.

    During the evening of January 12, 1999, following the approval of the merger
agreement and related matters by the Casella board and the KTI board, Casella
and KTI finalized, executed and delivered the merger agreement and related
documents. A joint public announcement of the merger was made by Casella and KTI
on the morning of January 13, 1999.

                                       27
<PAGE>
    Following the announcement of the merger, Casella and KTI and their
representatives took actions necessary to close the merger, including filing
this proxy statement/prospectus with the Securities and Exchange Commission and
a Hart-Scott-Rodino Pre-merger Notification and Report Form with the Department
of Justice and the Federal Trade Commission.

    On February 22, 1999, KTI publicly announced that it had restated its
financial results for each of the first three quarters of 1998, resulting in no
change to total earnings per share for such nine month period but resulting in a
shift in its earnings per share in the three quarters.

    On March 3, 1999 and again on March 4, 1999, the Casella board held
telephonic meetings to discuss KTI's restatement of its financial results and
other due diligence matters relating to the merger and to discuss progress being
made in connection with the merger.

    On March 30, 1999, KTI publicly announced the results of its fourth quarter
of 1998, which were substantially lower than its expected operating results for
that quarter.

    Between March 30, 1999 and April 14, 1999, representatives of Casella and
KTI and their respective financial advisors held a number of discussions in
which Casella indicated that it believed that KTI may have breached the merger
agreement and expressed the view that the exchange ratio should be revised to
reflect KTI's financial difficulties. During these discussions, while KTI
maintained that Casella was still bound by its obligations under the merger
agreement, KTI indicated that, in order to avoid having to engage in litigation
relating to the merger agreement, which would cause uncertainty and distract KTI
management, it might be willing to consider an appropriate adjustment in the
exchange ratio.

    On March 23, 1999 and again on April 6, 1999, the KTI board held telephonic
meetings to discuss the status of the merger and KTI's alternatives if Casella
terminated the merger agreement. During these meetings KTI's management also
presented its view on KTI's business prospects, including the view that, due to
the adverse results for the fourth quarter of 1998, KTI's ability, as an
independent company, to raise additional capital on satisfactory terms was
substantially and negatively impacted.

    During this period, the parties did not reach agreement, and on April 14,
1999, Casella notified KTI in writing of its intention to terminate the merger
agreement upon the expiration of the 30-day cure period set forth in the merger
agreement and issued a public announcement to such effect. Casella's notice
alleged breaches by KTI of, among other things, representations and warranties
on financial statements, contingent liabilities, financial condition, operations
and properties and environmental compliance. On April 20, 1999, KTI responded to
Casella's notice of termination by advising Casella in writing that Casella had
no basis for terminating the merger agreement.

    On April 16, 1999, KTI announced that it would not be able to file its
annual report on Form 10-K with the Securities and Exchange Commission on a
timely basis due to the developments regarding the merger. Additionally, on
April 28, 1999, KTI announced earnings for the first quarter of 1999 that were
$0.10 per share before certain special charges and $0.07 per share after such
charges.

    Between April 14, 1999 and May 12, 1999, the parties, together with their
financial advisors, continued to discuss a possible revision to the exchange
ratio. During the week of May 3, 1999, Messrs. Casella and Pirasteh reached a
tentative agreement, subject to the approval of the parties' respective boards
of directors and appropriate fairness opinions, on a revised exchange ratio of
0.59 of a share of Casella Class A common stock for each share of KTI common
stock. Messrs. Casella and Pirasteh reached this tentative agreement after
several extended discussions of different exchange ratios and narrowing the
range of ratios to 0.50 to 0.65. When Mr. Casella expressed the view that an
exchange ratio of 0.60 of a share of Casella Class A common stock for each share
of KTI common stock was not warranted, Mr. Pirasteh suggested 0.59 of a share of
Casella Class A common stock for each share of KTI common stock.

    On May 11, 1999, the Casella board held a telephonic meeting to discuss the
revised exchange ratio, certain due diligence matters relating to KTI and the
proposed amendment to the merger agreement. The board discussed the potential
effects of proceeding and of not proceeding with the merger.

    On May 11, 1999, the KTI board held a telephonic meeting to discuss the
proposed amendments to the merger agreement. The KTI board discussed the
fairness of proceeding with the merger at the proposed exchange ratio and the
ability of KTI to continue as an independent company in the absence of the
merger. The KTI board also discussed the potential effects on KTI and KTI
shareholders of pursuing its rights under the merger agreement through
litigation.

    On May 12, 1999, the Casella board held a telephonic meeting to consider the
approval of the amendment to the merger agreement. Members of Casella's
management team and financial and legal advisors also attended the meeting. At
the board meeting, Donaldson, Lufkin & Jenrette delivered its written and oral
opinion to the Casella board that, as of such date, and based upon and subject
to the assumptions made, matters considered and limitations on the review
undertaken set forth in the Donaldson, Lufkin & Jenrette opinion, the
0.59-for-one exchange ratio was fair to Casella and its stockholders from a
financial point of view. At the meeting, the Casella board unanimously approved
the amendment to the merger agreement, and unanimously recommended that the
holders of Casella common stock vote to approve the issuance of shares of
Casella Class A common stock to KTI shareholders in connection with the merger,
as amended.

    On May 12, 1999, the KTI board met to consider the approval of the proposed
amendments to the merger agreement. Members of KTI's management team and
financial and legal advisors also attended the meeting. At the meeting, each of
Credit Suisse First Boston and CIBC World Markets presented its financial
analyses with respect to the 0.59-for-one exchange ratio and delivered separate
opinions to the KTI board that, as of that date and based upon and subject to
the matters stated in their respective opinions, the 0.59-for-one exchange ratio
was fair, from a financial point of view, to the holders of KTI common stock. In
response to questions from KTI directors, both financial advisors indicated that
they had not been approached by, or made aware of, any third parties that were
interested in entering into an alternative transaction with KTI. The KTI board
also discussed the issues set forth in Casella's letter giving notice of its
intention to terminate the merger agreement. The KTI board weighed the prospects
of continuing as an independent company while pursuing its rights under the
merger agreement through litigation against approving a merger with Casella at
the proposed 0.59-for-one exchange ratio. At the meeting, the KTI board
unanimously approved the amendments to the merger agreement, and unanimously
recommended that the holders of KTI common stock vote to approve the merger
agreement, as amended.

    During the evening of May 12, 1999, following approval of the amendment to
the merger agreement and related matters by the Casella board and the KTI board,
Casella and KTI finalized, executed and delivered the amendment to the merger
agreement and related documents. A joint public announcement of the amendment to
the merger agreement was made by Casella and KTI on the morning of May 13, 1999.

    On August 15, 1999, KTI publicly announced the results of its second quarter
of 1999, which were substantially lower than its expected operating results for
that quarter.

    Following the release of KTI's financial results for the second quarter,
Casella and KTI and their representatives continued to take actions to close the
merger prior to September 30, 1999, when the agreement would be terminable by
either party. On September 5, 1999, Messrs. Casella and Bohlig informed Mr.
Pirasteh that they did not believe that the merger could be closed by
September 30, and, based on KTI's results of operations for the second quarter,
proposed a second amendment to the merger agreement which would reduce the
exchange ratio and provide Casella with an additional board seat in exchange for
providing KTI with greater certainty that the merger would close. In addition,
the

                                       29
<PAGE>
amendment would require as a condition of the merger that each of Messrs.
Pirasteh, John Casella, Bohlig, Sergi, Cifor and Garrett would sign lock-up
agreements whereby they agreed not to sell their shares for a period of
365 days after the merger. Although various exchange ratios between 0.50 to 0.52
were discussed, no agreement was reached at that time.

    On September 7, 1999, the KTI board held a telephonic meeting to discuss the
proposed second amendment to the merger agreement. The KTI board discussed the
fairness of proceeding with the merger at exchange ratios being discussed,
ranging from 0.50 to 0.52, and the likelihood that the merger would be
consummated in the absence of the second amendment. The KTI board considered the
fact that no person had approached KTI or its financial advisors to express an
interest in entering into an alternative transaction with KTI. The KTI board
also discussed the prospects of attempting to extend the date after which either
party could terminate the merger agreement if the merger were not yet
consummated through litigation. In order to minimize KTI's expenses, the KTI
board determined to seek an opinion regarding the fairness of the new exchange
ratio from only one financial advisor, rather than from two advisors as had been
done previously. The KTI management decided to request the opinion from CIBC
World Markets, rather than Credit Suisse First Boston. Neither CIBC World
Markets nor Credit Suisse First Boston provided any financial advice to KTI
during the period after May 12, 1999 until September 7, 1999.

    On the morning of September 8, 1999, the Casella board held a telephonic
meeting to discuss the proposed second amendment at the exchange ratios being
discussed, ranging from 0.50 to 0.52, and related matters. Casella's legal
advisors also participated in the meeting. At that meeting, the board discussed,
among other things:

    - the terms of the proposed amendment, including the reduction in the
      exchange ratio and the additional board seat to be filled by Casella;

    - KTI's business and assets;

    - the anticipated synergies and other prospective benefits of the merger,
      and the fairness of the modified exchange ratio;

    - Casella's rights under the agreement as still in effect to terminate the
      merger agreement if the merger were not completed by September 30, 1999
      (including the potential for litigation if the agreement were terminated
      on this basis); and

    - the impact of proceeding or not proceeding with the merger on Casella's
      future business opportunities.

    In addition, the Casella board considered the advisability of conditioning
the second amendment on the receipt of an updated fairness opinion. In assessing
whether such an opinion was advisable, the Casella board considered a number of
factors. Among other things, the board considered the following:

    - that, due to the substantial period of time that had elapsed since merger
      discussions were initiated, Casella management had become increasingly
      familiar with KTI's assets, operating management and financial results;

    - Casella had continued to conduct due diligence throughout the KTI
      organization, and as a result had an increasingly significant
      understanding of the nature and scope of problems facing KTI as well as
      the means for addressing those problems;

    - Casella had further developed its integration plan, and continued to
      assess the savings and other synergies and growth opportunities which
      would benefit Casella and its existing assets on a post-merger basis but
      which would not be reflected in a financial analysis of KTI;

                                       30
<PAGE>
    - Casella management's long and significant experience in making
      acquisitions on behalf of the company, including its demonstrated ability
      to negotiate appropriate purchase prices and to successfully integrate
      those acquisitions into the company as projected;

    - Casella's long familiarity as a customer of KTI with significant KTI
      assets;

    - the willingness of members of Casella management to sign lock-up
      agreements in connection with the merger; and

    - the Casella board's long and open communication with Casella management
      relating to all company matters, including during the discussions with
      KTI, as well as the numerous lengthy conversations among the members of
      the Board relating to the transaction.

    Based on these factors, the Casella board determined that it was adequately
informed with respect to the merger, and that a fairness opinion would not
provide it with a significant benefit in its consideration of the proposed
amendment.

    During the day on September 8, 1999, Messrs. Casella and Pirasteh reached
agreement, subject to the approval of their respective boards of directors, on
an exchange ratio of 0.51-for-one.

    On September 8, 1999, the KTI board held a telephonic meeting to consider
the approval of the proposed second amendment to the merger agreement, subject
to the receipt of an opinion from a financial advisor to the effect that the
proposed 0.51-for-one exchange ratio is fair to the holders of KTI common stock
from a financial point of view. Members of KTI's management team and legal
advisors also participated in the meeting. The KTI board weighed the prospects
of consummating the merger in the absence of the second amendment against
approving a merger with Casella at the proposed 0.51-for-one exchange ratio. The
KTI board also discussed the prospects of continuing as an independent company
in the absence of the merger, in light of KTI's operating results for its second
quarter and its future expected operating results. At the meeting, the KTI board
unanimously approved the second amendment to the merger agreement, subject to
the receipt of an opinion, satisfactory in form and substance to KTI in its
reasonable judgment, from a financial advisor to the effect that the proposed
0.51-for-one exchange ratio is fair to the holders of KTI common stock from a
financial point of view.

    In the evening of September 8, 1999, the Casella board held a telephonic
meeting to consider the approval of the proposed second amendment. Casella's
legal advisors also participated in the meeting. The board considered the terms
of the proposed amendment and reviewed the matters considered by the board at
its meeting earlier in the day. At the meeting, the board unanimously approved
the second amendment to the merger agreement. The board's decision to recommend
the merger was not at all based on the opinions it previously received from
Donaldson, Lufkin & Jenrette Securities Corporation.

    During the evening of September 8, 1999, following approval of the amendment
to the merger agreement, Casella and KTI finalized, executed and delivered the
amendment to the merger agreement. A joint public announcement of the amendment
to the merger agreement was made by Casella and KTI on the morning of
September 9, 1999.

    On September 15, 1999, the KTI board held a telephonic meeting during which
CIBC World Markets made an oral presentation of its financial analyses with
respect to the 0.51-for-one exchange ratio, and set forth that in CIBC World
Markets' opinion the exchange ratio was fair, from a financial point of view, to
the holders of KTI common stock. CIBC World Markets subsequently confirmed their
opinion by delivery of a written opinion dated September 15, 1999 to the KTI
board. At the meeting, the KTI board unanimously determined that CIBC World
Markets' fairness opinion was reasonably acceptable.

    On September 17, 1999, the Casella board held a telephonic meeting to
consider for approval a proposed third amendment to the merger agreement. The
proposed amendment would reflect that the

                                       31
<PAGE>
merger would be treated for accounting purposes as a purchase rather than as a
pooling-of-interests as previously contemplated. The Casella board had been
advised that such accounting treatment would likely be required because Casella
management was strongly considering the possibility of divesting certain
underperforming KTI assets following the merger, although no specific assets had
yet been identified and Casella was not engaged in discussions with any third
party to divest of such assets. The assets being considered for divestiture are
non-core assets in KTI's commercial recycling and finished products divisions
which constitute approximately 10 to 15 percent of KTI's gross assets. At the
meeting, the board unanimously approved the third amendment, subject to
management confirming the accounting treatment with the company's auditors and
determining that there would be no adverse tax consequences to the tax treatment
of the merger. At November 9, 1999, Casella was engaged in preliminary
discussions with third parties regarding potential asset sales, although no
definitive agreements had been reached.

    On September 21, 1999, the KTI board held a telephonic meeting to consider
for approval the proposed third amendment to the merger agreement. At the
meeting, the board unanimously approved the third amendment to the merger
agreement, subject to management determining that there would be no adverse
consequences to the tax treatment of the merger or on CIBC World Markets'
fairness opinion.

    On September 23, 1999, CIBC World Markets was advised that the merger is
anticipated to be accounted for as a purchase rather than as a
pooling-of-interests transaction. In a letter dated September 23, 1999, CIBC
World Markets reaffirmed the conclusions of its written opinion dated
September 15, 1999, subject to the qualifications and limitations contained in
the September 15, 1999 letter. The September 23, 1999 letter is attached as
Annex B-2 to this proxy statement/prospectus and is incorporated by reference
herein. On September 23, 1999, Casella and KTI executed and delivered the third
amendment to the merger agreement. A joint public announcement of the amendment
to the merger agreement was made by Casella and KTI later the same day.

REASONS FOR THE MERGER

    JOINT REASONS FOR THE MERGER

    The Casella board and the KTI board believe that the merger represents a
highly favorable strategic opportunity for two companies with complementary
business operations and geographical presence. The two boards believe that the
combined company will have greater financial strength, operational efficiencies,
earning power and growth potential than either Casella or KTI would have on its
own. The Casella board and the KTI board identified a number of potential
benefits of the merger which they believe will contribute to the success of the
combined company, including the following:

    - COMPLEMENTARY OPERATIONS. Casella is a strong regional non-hazardous solid
      waste services company with collection and disposal operations primarily
      in Vermont, New Hampshire, Maine, upstate New York, Massachusetts and
      northern Pennsylvania. KTI has substantial waste-to-energy and recycling
      facilities and operations in Casella's core northeastern market and in
      contiguous areas of Pennsylvania, New Jersey, New York, Connecticut and
      Massachusetts, as well as in a number of additional states, primarily in
      the eastern United States. As of September 1, 1999, KTI processed solid
      waste through a network of 50 facilities in 19 states, including six
      waste-to-energy facilities, 22 material recycling facilities and 11
      finished products facilities. The existence of KTI's waste-to-energy and
      recycling facilities within Casella's core market will permit greater
      integration of Casella's solid waste services and lower disposal costs.
      Casella's collection services, in turn, will add additional volume to
      KTI's waste-to-energy operations. The disposal capacity of KTI's
      facilities will also provide the opportunity for Casella to expand its
      collection services through acquisitions both within its core markets and
      in the expanded contiguous markets where KTI facilities exist.

                                       32
<PAGE>
    - OPERATIONAL EFFICIENCIES OF THE COMBINED COMPANY. Each board believes that
      the merger will result in cost savings. The managements of KTI and Casella
      have identified approximately $9.0 million of annual cost savings expected
      to result from the merger, including approximately $3.1 million from
      disposal of solid waste at facilities owned by the combined company rather
      than through third parties, approximately $3.8 million from combining
      administrative operations and reducing redundant capabilities,
      approximately $900,000 from recycling efficiencies, approximately $800,000
      from lower interest costs due to improved cash flow from operations, and
      approximately $400,000 from consolidation of overlapping collection
      routes. A portion of these anticipated annual operational efficiencies
      (based on the timing of the merger) is expected to be realized in fiscal
      2000, with the full $9.0 million expected to be realized commencing in
      fiscal 2001.

    - GROWTH OPPORTUNITIES. The combined company's strategy of continued growth
      through acquisitions will be enhanced by the existence of substantial KTI
      facilities within Casella's core northeastern market, in contiguous
      states, and throughout the eastern United States beyond Casella's core
      market.

    - COMPATIBLE STRATEGIES. The compatible strategies of each of KTI and
      Casella of expanding geographically and further integrating their
      operations are also satisfied by this strategic business combination,
      which creates a combined company with greater resources, more fully
      integrated operations, and a more diversified range of services in the
      solid waste disposal and recycling industry. Both companies have grown
      rapidly through acquisitions, and their combined strength will be
      advantageous in seeking additional future acquisitions.

    - EXPECTED PROFITABILITY. The merger is expected to be accretive to
      Casella's earnings in fiscal year 2001 by approximately $0.12 per share,
      and the combined company projects earnings per share in fiscal year 2001
      of approximately $1.46 per share, compared to projected earnings of
      approximately $1.34 per share for Casella as a stand-alone entity for the
      fiscal year ending April 30, 2001. For the fiscal year ending April 30,
      2000, the merger is expected to be accretive by approximately $0.01 per
      share, reflecting combined company earnings per share of approximately
      $1.04, compared to projected earnings of approximately $1.03 per share for
      Casella on a stand-alone basis. These projected results for fiscal year
      2001 reflect a downward adjustment from projections previously released on
      September 9, 1999 as a result of the reclassification of KTI's deferred
      revenues on a pro forma combined basis.

    - LARGER CRITICAL MASS. Immediately following the merger, the annualized
      revenues and EBITDA of the combined company based on results in July, 1999
      and acquisitions closed through July 31, 1999 would be approximately $488
      million and $123 million, respectively, and total assets of the combined
      company would be in excess of $790 million. Its operations will be
      significantly more diversified than the operations of either Casella or
      KTI prior to the merger. Greater vertical integration of combined
      operations is expected to increase profitability and help the combined
      company achieve sustained earnings growth. For the fiscal year ending
      April 30, 2000, the combined company has publicly projected revenues of
      approximately $505 million and EBITDA of approximately $127 million. Prior
      to the execution of the merger agreement in January 1999, KTI delivered
      projections for KTI on a stand-alone basis to Casella. These projections,
      dated November 30, 1998, reflected revenues of $313 million and EBITDA of
      $65 million for the year ending December 31, 1999 and revenues of $409
      million and EBITDA of $92 million for the year ending December 31, 2000.
      After KTI announced its results for the quarter ended March 31, 1999, and
      prior to the amendment to the merger agreement on May 12, 1999, KTI
      delivered revised projections, dated May 3, 1999, for KTI on a stand-alone
      basis, showing revenues of $292 million and EBITDA of $53 million for the
      year ending December 31, 1999 and revenues of $320 million and EBITDA of
      $62 million for the year ending December 31, 2000. Following KTI's
      announcement of its results for the quarter ended June 30, 1999, and in

                                       33
<PAGE>
      connection with the amendments to the merger agreement in September 1999,
      Casella did not utilize KTI projections but instead based its models
      solely on the results of its due diligence. Prior to the execution of the
      merger agreement in January 1999, Casella delivered projections for
      Casella on a stand-alone basis to KTI. These projections showed revenues
      of $164 million and EBITDA of $46 million for the fiscal year ended
      April 30, 1999, revenues of $235 million and EBITDA of $68 million for the
      fiscal year ended April 30, 2000 and revenues of $297 million and EBITDA
      of $86 million for the fiscal year ended April 30, 2001. The Casella and
      KTI boards believe that greater size and financial strength will improve
      the combined company's ability to compete with other large and well
      capitalized companies in the solid waste, recycling and waste-to-energy
      markets.

    - INCREASED LIQUIDITY OF THE COMMON STOCK OF THE COMBINED COMPANY. The
      increased number of shares in the public market following the merger is
      expected to result in increased liquidity for the Casella Class A common
      stock.

    CASELLA'S CONSIDERATION OF FACTORS FOR AND AGAINST THE MERGER

    In reaching its conclusion to approve the amended merger agreement and the
proposals set forth in the notice of meeting, the Casella board consulted with
management of Casella, as well as with its financial, accounting and legal
advisors, and considered the factors described above under "Joint reasons for
the merger" and the following factors, which together encompassed all the
material factors the Casella board considered. Among the factors considered by
the Casella board were the following factors in favor of the merger:

    - the current economic, financial and business environment generally and the
      present and anticipated environment in the waste management industry in
      particular, including the strategic options which might become available
      to Casella if it were or were not to proceed with the merger and the
      effects on Casella of potential further consolidation within the industry;

    - the judgment, advice and analysis of Casella's management with respect to
      the strategic, financial and operational benefits of the merger, based in
      part on the business, financial, accounting and legal due diligence
      investigations performed with respect to KTI, as well as the Casella
      board's own knowledge of Casella, KTI and their respective businesses;

    - the effectiveness of the merger in implementing and accelerating Casella's
      long-term growth strategy compared to Casella's continuing as a
      stand-alone entity;

    - the financial condition, results of operations, businesses and prospects
      of Casella and KTI, including, but not limited to, information regarding
      their respective recent and historic stock prices and earnings
      performance;

    - the express terms of the merger agreement, which were viewed as providing
      an equitable basis for the merger from the standpoint of Casella;

    - the $10.0 million termination fee to be paid by KTI to Casella and the
      reimbursement of up to $3.0 million of expenses by KTI to Casella in the
      event of the termination of the merger agreement for reasons identified in
      the merger agreement;

    - the stock option on 19.9% of KTI common stock granted by KTI to Casella;

    - the fact that of the 11 members of the board following the merger, seven
      would be representatives of Casella or designated by John W. Casella;

    - the other proposed corporate governance arrangements with respect to the
      board and management of the combined company following the merger;

    - the likelihood of the merger being approved by the appropriate regulatory
      authorities;

                                       34
<PAGE>
    - the effect of the merger on Casella's other constituencies, including its
      senior management and other employees, customers and the communities
      served by Casella;

    - the opportunity presented by a combination with KTI to expand Casella's
      business beyond its current geographic presence in the northeast; and

    - the implications of adding KTI's recycling business, waste-to-energy
      plants and other operations to the traditional solid waste management
      business of Casella.

    The Casella board also considered factors which weighed against the merger,
including:

    - KTI's recent financial and operating difficulties and the restatement of
      its quarterly results;

    - the difficulty and management distraction inherent in integrating two
      large and geographically dispersed operations and the risk that the
      operational efficiencies and benefits sought in the merger would not be
      achieved;

    - the number of shares of Casella Class A common stock to be issued to KTI
      shareholders in the merger, and the fact that, based on trading prices for
      Casella Class A common stock and KTI common stock immediately prior to the
      announcement of the exchange ratio, the KTI shareholders would receive a
      premium over the then current market price of KTI common stock;

    - the risk that the merger would not be consummated, and the effect that the
      public announcement of the merger would have on the market price of
      Casella Class A common stock; and

    - the reimbursement of up to $3.0 million of expenses by Casella to KTI in
      the event of the termination of the merger agreement for reasons
      identified in the merger agreement.

    On balance, considering all the foregoing factors and risks, the Casella
board concluded that the terms of the merger are fair to, and in the best
interests of the Casella stockholders, and the Casella board unanimously
approved the merger agreement, as amended, and declared it advisable.
Accordingly, the Casella board recommends that the Casella stockholders vote to
approve the shares issuable to KTI shareholders pursuant to the merger
agreement.

    KTI'S CONSIDERATION OF FACTORS FOR AND AGAINST THE MERGER

    In reaching its conclusion to approve the amended merger agreement, the KTI
board consulted with management of KTI, as well as with KTI's financial,
accounting and legal advisors, and considered the factors described above under
"Joint reasons for the merger" and the following factors, which together
encompassed all the material factors the KTI board considered. Among the factors
considered by the KTI board were the following factors in favor of the merger:

    - the financial performance and condition, businesses and prospects of
      Casella and KTI, including, but not limited to, information regarding
      their respective recent and historic stock prices and earnings
      performance;

    - the effectiveness of the merger in implementing and accelerating KTI's
      basic long-term growth strategy;

    - the KTI board's own knowledge of Casella, KTI and their respective
      businesses;

    - the effect on KTI shareholders of KTI continuing as a stand-alone entity
      compared to the effect of KTI combining with Casella, in light of the
      factors summarized here with respect to the financial condition and
      prospects of the two companies on a stand-alone basis and of the combined
      company, and the current economic, financial and business environment,
      taking into account, in the case of KTI, the anticipated difficulty of
      raising additional capital and KTI's series of defaults under its credit
      facility;

                                       35
<PAGE>
    - the fact that, despite the public announcement of the merger agreement and
      the public announcement of Casella's allegations of KTI's breaches of the
      merger agreement, no person had approached KTI or its financial advisors
      to express an interest in engaging in an alternative transaction with KTI;

    - the uncertainty of success and the timing of resolution of any litigation
      involving the merger agreement;

    - the benefits that would accrue to KTI shareholders as holders of Casella
      Class A common stock after a merger with KTI;

    - the ability of the KTI board to confirm the fairness of the merger by
      receiving an opinion by September 30, 1999, satisfactory in form and
      substance to KTI in its reasonable judgment, from a financial advisor to
      the effect that the 0.51-for-one exchange ratio is fair to the holders of
      KTI common stock from a financial point of view, or to terminate the
      merger agreement without liability, a fairness opinion which was
      subsequently received from CIBC World Markets on September 15, 1999;

    - the increased likelihood that the merger will be consummated, due to the
      elimination of certain conditions to the obligations of Casella and the
      extension of the date after which either party may terminate the merger
      from September 30 to December 15, 1999;

    - the fact that the current chairman of the KTI board, Ross Pirasteh, and
      president, Martin J. Sergi, will join the senior management team of the
      combined company as chairman of the board and executive vice
      president--business development, respectively;

    - the confluence of the corporate cultures of Casella and KTI;

    - the reimbursement of up to $3.0 million of expenses by Casella to KTI in
      the event of the termination of the merger agreement for reasons
      identified in the merger agreement;

    - the advice of KTI's counsel that the merger should be treated as a
      tax-free reorganization; and

    - the effect of the merger on KTI's other constituencies, including its
      senior management and other employees, customers and the communities
      served by KTI.

    The KTI board also considered factors which weighed against the merger,
including:

    - the difficulty and management distraction inherent in integrating two
      large and geographically dispersed operations and the risk that the
      operational efficiencies and benefits sought in the merger would not be
      fully achieved;

    - the risk that the merger would not be consummated and that KTI, having
      signed the second amendment to the merger agreement, would no longer have
      the ability to pursue its rights under the first amendment to the merger
      agreement, including the 0.59 exchange ratio, through litigation;

    - the substantial charges, approximately $25 million, expected to be
      incurred by the combined company in connection with the merger;

    - the $10.0 million termination fee to be paid by KTI to Casella and the
      reimbursement of up to $3.0 million of expenses by KTI to Casella in the
      event of the termination of the merger agreement for reasons identified in
      the merger agreement and the stock option granted by KTI to Casella to
      purchase 19.9% of the outstanding stock of KTI; and

    - the fact that John W. Casella and Douglas R. Casella hold in the aggregate
      988,200 shares of Casella's Class B common stock entitling them to ten
      votes per share, and the fact that they will control approximately 35.4%
      of the voting power of the combined company.

    The KTI board did not undertake to make any specific determination as to
whether any particular factor, or any aspect of any particular factor, in
isolation, was favorable or unfavorable to its ultimate determination. Examined
separately, some of the analyses contained in the financial presentation of CIBC
World Markets reflected an implied exchange ratio that is different, some
higher, some lower, than the exchange ratio provided for in the merger.
Specifically, certain aspects of the analyses relating to the "KTI Contribution
Analysis" and the "KTI Pro Forma Merger Analysis" reflected an implied exchange
ratio that is higher than the exchange ratio provided for in the merger. As a
result, the actual ratios viewed in isolation, could appear inadequate. The KTI
board did not form a conclusion as to whether any individual analysis,
considered in isolation, supported or failed to support a determination that the
exchange ratio was fair. Rather, the KTI board reached a general consensus,
based on the totality of the factors described above, that the merger was in the
best interest of KTI and its shareholders. On balance, considering all the
foregoing factors and risks, the KTI board concluded that the terms of the
merger are fair to, and in the best interests of KTI shareholders; and the KTI
board unanimously approved the merger agreement, as amended and declared it
advisable. Accordingly, the KTI board recommends that KTI shareholders vote to
approve the merger.

OPINION OF KTI FINANCIAL ADVISOR

    KTI retained CIBC World Markets Corp. to render its opinion to the KTI board
as to the fairness, from a financial point of view, to the shareholders of KTI,
of the exchange ratio provided in the draft merger agreement dated January 11,
1999, as amended by Amendment No. 1 thereto dated May 11, 1999 and Amendment
No. 2 thereto dated September 8, 1999. The KTI board selected CIBC World Markets
because CIBC World Markets is an internationally recognized investment banking
firm that has substantial experience in the solid waste and environmental
services industry and is familiar with KTI and its businesses. As part of its
investment banking business, CIBC World Markets is regularly engaged in the
valuation of businesses and securities in connection with mergers, acquisitions,
underwritings, sales and distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes.

    On September 15, 1999, CIBC World Markets delivered an oral opinion, which
opinion was subsequently confirmed by delivery of a written opinion dated
September 15, 1999, to the KTI board that, as of such date, the exchange ratio
provided in the amended merger agreement was fair, from a financial point of
view, to the shareholders of KTI. The exchange ratio was determined through
negotiations between KTI and Casella. CIBC World Markets did not provide advice
to KTI during the course of such negotiations.

    The full text of the CIBC World Markets fairness opinion, which sets forth
certain assumptions made, certain procedures followed and certain matters
considered by CIBC World Markets, is attached as Annex B-1 to this proxy
statement/prospectus and is incorporated by reference herein. This summary is
qualified in its entirety by reference to the CIBC World Markets fairness
opinion. KTI and Casella each provided CIBC World Markets with its respective
financial forecasts. With respect to the financial forecasts and other data
concerning KTI reviewed by CIBC World Markets, the management of KTI advised
CIBC World Markets that such forecasts and other data had been reasonably
prepared on bases reflecting such management's best currently available
estimates and judgment as to the future financial performance of KTI. With
respect to the financial forecasts and other data concerning Casella reviewed by
CIBC World Markets, the management of Casella advised CIBC World Markets that
such forecasts and other data had been reasonably prepared on bases reflecting
such management's best currently available estimates and judgment as to the
future financial performance of Casella. CIBC World Markets relied upon the
estimates of the managements of KTI and Casella of the operating synergies
achievable as a result of the merger and its discussion of such synergies with
the respective managements of KTI and Casella.

    In connection with CIBC World Markets review, CIBC World Markets did not
assume responsibility for independent verification of any of the information
considered for its review and has relied upon such information being complete
and accurate in all respects. In arriving at its opinion, CIBC World Markets
neither made nor obtained any independent evaluation or appraisal of the assets
or liabilities, contingent or otherwise, of KTI or Casella, nor was it furnished
with any such evaluations or appraisals. CIBC World Markets also assumed,
without independent verification, the accuracy of the advice and conclusions of
the parties' legal counsel and accountants with respect to tax and accounting
matters, including, without limitation, the treatment of the merger as a
tax-free reorganization for federal income tax purposes and the accounting of
the merger as a pooling-of-interests business combination. Upon learning that
the merger would be accounted for under the purchase method of accounting rather
than the pooling method, CIBC World Markets reviewed each of its analyses to
determine the impact, if any, of such change. CIBC World Markets concluded that
the change in accounting method had no impact on the implied exchange ratios
derived from its analyses and was immaterial to its overall opinion. The CIBC
World Markets fairness opinion was necessarily based on information available to
CIBC World Markets and on the general economic, financial and stock market
conditions and circumstances as they existed and could be evaluated by CIBC
World Markets on the date of the CIBC World Markets fairness opinion. No
limitations were imposed by KTI or Casella on CIBC World Markets with respect to
the investigations made or procedures followed by CIBC World Markets.

    THE SUMMARY OF THE WRITTEN CIBC WORLD MARKETS FAIRNESS OPINION SET FORTH IN
THIS PROXY STATEMENT/ PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO
THE FULL TEXT OF THE OPINION WHICH IS ATTACHED AS ANNEX B-1 HERETO. KTI
SHAREHOLDERS ARE URGED TO, AND SHOULD, READ THIS OPINION CAREFULLY IN ITS
ENTIRETY IN CONJUNCTION WITH THIS PROXY STATEMENT/PROSPECTUS FOR THE ASSUMPTIONS
MADE, MATTERS CONSIDERED AND LIMITS OF THE REVIEW BY CIBC WORLD MARKETS. THE
CIBC WORLD MARKETS FAIRNESS OPINION IS DIRECTED ONLY TO THE FAIRNESS, FROM A
FINANCIAL POINT OF VIEW, OF THE EXCHANGE RATIO PROVIDED IN THE AMENDED MERGER
AGREEMENT AND DOES NOT ADDRESS ANY OTHER ASPECT OF THE MERGER. THE CIBC WORLD
MARKETS FAIRNESS OPINION DOES NOT CONSTITUTE AN OPINION AS TO THE PRICE AT WHICH
THE KTI COMMON STOCK OR THE CASELLA CLASS A COMMON STOCK WILL ACTUALLY TRADE AT
ANY TIME. THE CIBC WORLD MARKETS FAIRNESS OPINION DOES NOT CONSTITUTE A
RECOMMENDATION TO KTI SHAREHOLDERS AS TO HOW SUCH SHAREHOLDERS SHOULD VOTE WITH
RESPECT TO THE APPROVAL OF THE MERGER.

    In rendering its opinion, CIBC World Markets:

    - reviewed the merger agreement, draft exhibits thereto, Amendment No. 1
      thereto dated May 12, 1999 and Amendment No. 2 thereto dated September 8,
      1999;

    - reviewed the historical financial statements and financial forecasts and
      other information prepared by representatives of KTI and Casella;

    - reviewed certain publicly available information for KTI and Casella,
      including periodic and other reports filed with the Securities and
      Exchange Commission;

    - reviewed the reported market prices and trading volumes for KTI and
      Casella shares;

    - held discussions with the senior management and representatives of KTI and
      Casella concerning each company's historical and current operations,
      financial condition and prospects; and

    - reviewed such other documents and financial, economic and market
      information and made such other investigations as we deemed appropriate
      for the purposes of the opinion.

    The financial forecasts reviewed by CIBC World Markets that were prepared by
representatives of Casella are the same projections that Casella provided to
KTI. See "Reasons for the Merger--Joint reasons for the merger--Larger critical
mass." The following is a summary of all material financial

analyses used by CIBC World Markets in connection with providing its opinion to
the KTI board on September 15, 1999.

    In establishing the range of exchange ratios resulting from the application
of each of the analyses, CIBC World Markets made qualitative judgments as to the
meaningfulness of the valuation measurements. The judgments were based upon the
number and similarity of comparable companies and transactions, as well as the
predictability and volatility of future earnings when assessing the relative
significance of the discounted cash flow analysis described below. The relative
appropriateness of certain other valuation measurements, such as operating cash
flow or price/earnings multiples, as used generally for comparative purposes,
were also taken into account in making such judgments.

    Based on the closing price of Casella Class A common stock of $15.56 on
September 10, 1999, the last trading day prior to preparation of materials for
CIBC World Markets presentation to the KTI board, the exchange ratio results in
an implied price per share of KTI common stock of $7.94. This implied value is
based upon the relative market valuations of the KTI common stock and the
Casella Class A common stock as of such date, which may change prior to
consummation of the merger.

    COMPARABLE COMPANIES ANALYSIS.  CIBC World Markets performed a comparable
companies analysis of KTI and Casella to evaluate the exchange ratio. CIBC World
Markets compared KTI to two groups of environmental services companies which are
publicly traded and are deemed by CIBC World Markets to be similar to KTI based
on their business and operations. The first group consisted of the following
five solid waste management services companies:

    - Allied Waste Industries, Inc.

    - Capital Environmental Resource Inc.

    - Republic Services, Inc.

    - Waste Connections, Inc.

    - Waste Industries, Inc.

    The second group consisted of the following four resource recovery
/recycling companies:

    - FiberMark, Inc.

    - IMCO Recycling Inc.

    - Republic Group Incorporated

    - Wellman, Inc.

    CIBC World Markets compared Casella to the five solid waste management
services companies listed above which are publicly traded and are deemed by CIBC
World Markets to be similar to Casella based on their business operations.

                                       39
<PAGE>
    Using publicly available information, CIBC World Markets analyzed, among
other things, the market values and certain financial criteria for the
comparable companies including their:

    - revenue,

    - earnings before interest, taxes, depreciation and amortization,

    - earnings before interest and taxes and

    - net income, in each case, on an estimated basis, for the calendar years
      ending 1999 and 2000.

    In the case of KTI, CIBC World Markets derived 66 multiples in this analysis
and excluded 10 statistics that were statistically aberrational. In the case of
Casella, CIBC World Markets derived 37 multiples in this analysis and excluded
six statistics that were statistically aberrational. For each of the multiples
of revenue, EBITDA, EBIT and net income, CIBC World Markets took the high, low
and average for the comparable companies and applied these multiples to KTI's
and Casella's estimated results for the calendar years ending 1999 and 2000 to
derive a range of implied exchange ratios. The comparable company analysis
resulted in implied exchange ratios which ranged from a low of 0.20x to a high
of 0.79x, with an average of 0.41x, as compared to the exchange ratio in the
merger of 0.51x.

    COMPARABLE MERGERS AND ACQUISITIONS TRANSACTION ANALYSIS.  CIBC World
Markets performed a comparable mergers and acquisitions transaction analysis of
KTI and Casella to evaluate the exchange ratio. Using publicly available
information, CIBC World Markets analyzed the consideration paid in two groups of
selected environmental services merger and acquisition transactions. The first
group consisted of 15 selected merger and acquisition transactions involving
selected solid waste management companies deemed by CIBC World Markets to be
similar to KTI based on their business and operations:

    CIBC World Markets compared Casella to the 15 selected merger and
acquisition transactions listed above involving selected solid waste management
companies deemed by CIBC World Markets to be similar to Casella based on their
business and operations.

    CIBC World Markets calculated the multiples of the consideration paid in
relation to the acquired companies (a) revenue, (b) EBITDA, (c) EBIT and
(d) net income, in each case for the most recent annualized period ending prior
to the date of the announcement of the acquisition for which financial data were
available. In the case of KTI, CIBC World Markets derived 99 multiples in this
analysis and excluded 21 statistics that were statistically aberrational. In the
Case of Casella, CIBC World Markets derived 60 multiples in this analysis and
excluded 15 statistics that were statistically aberrational. For each of the
multiples of revenue, EBITDA, EBIT and net income, CIBC World Markets took the
high, low and average for the comparable transactions and applied these
multiples to KTI's and Casella's latest quarter annualized ("LQA") results for
the three months ended July 31, 1999 to derive a range of implied exchange
ratios. The comparable mergers and acquisitions transaction analysis resulted in
implied exchange ratios which ranged from a low of 0.16x to a high of 0.85x,
with an average of 0.43x, as compared to the exchange ratio in the merger of
0.51x.

    DISCOUNTED CASH FLOW ANALYSIS.  CIBC World Markets performed a discounted
cash flow analysis of KTI and Casella to evaluate the exchange ratio. In
conducting its analysis, CIBC World Markets relied on certain assumptions,
financial projections and other information provided by KTI and Casella
management. Using the information set forth in KTI's and Casella's projections,
CIBC World Markets performed discounted cash flow analyses of the projected
after-tax cash flows of KTI and Casella on a stand-alone basis for the twelve
month periods ending April 30, 2000 through April 30, 2004. This analysis
consisted of adding the discounted present value of the projected future cash
flows and the discounted present value of the terminal value at the end of the
reference period from KTI and Casella on a stand-alone basis, respectively. In
the case of KTI, CIBC World Markets then used discount rates ranging from 14% to
17% and calculated the terminal value by applying EBITDA multiples ranging from
5.5x to 6.5x to the projected EBITDA for KTI for the year ending April 30, 2004.
In the case of Casella, CIBC World Markets used discount rates ranging from 11%
to 14% and calculated the terminal value by applying EBITDA multiples ranging
from 7.0x to 8.0x to the projected EBITDA for Casella for the fiscal year ending
April 30, 2004. The Discounted Cash Flow Analyses resulted in implied exchange
ratios which ranged from a low of 0.24x to a high of 0.56x, with an average of
0.37x, as compared to the exchange ratio in the merger of 0.51x.

    KTI COMMON STOCK TRADING ANALYSIS.  To provide contextual data and
comparative market data, CIBC World Markets examined the history of the trading
prices and their relative relationships for KTI

                                       41
<PAGE>
common stock and Casella Class A common stock during the 12 month period from
September 8, 1998 to September 8, 1999 and the period from January 12, 1999 to
September 8, 1999. This information was presented solely to provide the KTI
board with background information regarding the stock prices of KTI and Casella
over the periods indicated. An analysis of the daily closing price ratio,
calculated as KTI's closing price divided by Casella's closing price, indicated
that the average daily closing price ratio during the period from May 13, 1999,
the date following the announcement of Amendment No. 1 to the merger agreement,
through September 8, 1999, the date of approval of Amendment No. 2 to the merger
agreement, ranged from a low of 0.42x to a high of 0.57x, with an average of
0.53x, as compared to the exchange ratio in the merger of 0.51x.

    KTI PRO FORMA MERGER ANALYSIS.  CIBC World Markets prepared pro forma
analyses of the financial impact of the merger. Using earnings estimates
prepared by KTI and Casella management for the years ending April 30, 2000, 2001
and 2002, CIBC World Markets compared the earnings per share of Casella's common
stock, on a stand-alone basis, to the EPS of the common stock of the combined
company. Based on the exchange ratio in the merger of 0.51x, this analysis
indicated that the proposed merger would be 6.3% accretive to KTI's earnings per
share in 2000, 3.4% dilutive in 2001 and 1.3% dilutive in 2002. The actual
results achieved by the combined company may vary from projected results and the
variations may be material.

    KTI CONTRIBUTION ANALYSIS.  CIBC World Markets analyzed KTI's and Casella's
relative contribution to the combined company with respect to total revenues,
EBITDA, EBIT, total assets, net income, book value and tangible book value. Its
analysis was made for the year ending April 30, 2000 based on projected results
for both KTI and Casella. With respect to the implied enterprise value of the
combined company (equity value plus associated debt less cash of KTI) this
analysis yielded the following results:

    The summary set forth above does not purport to be a complete description of
the analyses performed by CIBC World Markets. The preparation of a CIBC World
Markets fairness opinion involves various determinations as to the most
appropriate and relevant methods of financial analysis and the application of
these methods to the particular circumstances and, therefore, such an opinion is
not readily susceptible to summary description. Accordingly, notwithstanding the
separate factors summarized above, CIBC World Markets believes that its analyses
must be considered as a whole and that selecting portions of its analyses and
the factors considered by it, without considering all analyses and factors,
could create an incomplete or misleading view of the evaluation process
underlying its opinions. For example, in isolation the results of some analyses
reflect an implied exchange ratio that is higher or lower than the exchange
ratio provided for in the merger. CIBC World Markets did not form a conclusion
as to whether any individual analysis or factor, considered in isolation,
supported or

                                       42
<PAGE>
failed to support an opinion as to fairness from a financial point of view. In
performing its analyses for purposes of the CIBC World Markets fairness opinion,
CIBC World Markets made numerous assumptions with respect to industry
performance, business and economic conditions and other matters. In addition,
CIBC World Markets noted the dual class structure of Casella common stock. The
analyses performed by CIBC World Markets are not necessarily indicative of
actual values or future results, which may be significantly more or less
favorable than suggested by such analyses.

    ENGAGEMENT LETTER.  Pursuant to the terms of CIBC World Markets' engagement,
KTI has agreed to pay CIBC World Markets for its fairness opinion in connection
with the merger an aggregate fairness opinion fee of $3.0 million. KTI has also
agreed to reimburse CIBC World Markets for its reasonable out-of-pocket
expenses, including reasonable fees and expenses of legal counsel, and to
indemnify CIBC World Markets and certain related persons against certain
potential liabilities arising out of the engagement of CIBC World Markets,
including liabilities under the federal securities laws.

    In the ordinary course of business, CIBC World Markets may actively trade
the securities of both KTI and Casella for its own account and for the accounts
of its customers and, accordingly, may at any time hold a long or short position
in such securities. CIBC World Markets has provided financial advisory and
investment banking services to Casella in the past, including (a) acting as a
managing underwriter in an initial public offering of Casella Class A common
stock completed in October, 1997, and (b) acting as a managing underwriter in a
public offering of Casella Class A common stock completed in July, 1998, and has
in each case received usual and customary fees for rendering such services,
totaling approximately $2.0 million. CIBC World Markets acted as financial
advisor to FCR, Inc., a wholly-owned subsidiary of KTI, in connection with its
acquisition by KTI in 1998 and received aggregate compensation of approximately
$400,000.

INTERESTS OF EXECUTIVE OFFICERS AND DIRECTORS OF CASELLA AND KTI IN THE MERGER

    The executive officers of Casella and KTI who will continue after the merger
have interests in the merger that are in addition to their interests as Casella
or KTI shareholders generally. The Casella and KTI boards were aware of these
interests and considered them, among other matters, in approving the merger
agreement and the transactions contemplated thereby. These interests are as
follows:

    EMPLOYMENT AGREEMENTS.  In connection with the consummation of the merger,
Casella will enter into employment agreements with each of Messrs. John W.
Casella, Bohlig, Cifor, Pirasteh and Sergi. Each employment agreement commences
at the closing of the merger for a term of three years and is automatically
renewable for additional terms of one year. During the three years, each of
these employees will be entitled to a specified annual base salary and a bonus
consisting of cash, stock options or a combination thereof in an amount
determined by Casella's compensation committee prior to the conclusion of each
fiscal year, and to a severance package upon the termination of their
employment. The base salaries are as follows for the first year of the agreement
(which are equal to the base salaries payable to each such person immediately
prior to the merger):

<TABLE>
<S>                                                           <C>
Ross Pirasteh...............................................  $250,000
John W. Casella.............................................  $262,000
James W. Bohlig.............................................  $250,000
Jerry S. Cifor..............................................  $230,000
Martin J. Sergi.............................................  $250,000
</TABLE>

    Each employee has also agreed not to compete with Casella for a period of
two years after the termination of the employee's employment within 300 miles of
any facility operated by the combined company during the term of his employment.
In addition, each employee has agreed that during this period, he will not
solicit customers or accounts or other employees of the combined company. In the
event an employee were to terminate his employment voluntarily and as a result
he is not entitled to severance, the non-compete would not apply unless Casella
continues to pay the employee's base salary. In the event of a termination of
the employee's employment without cause, Casella will be required to

                                       43
<PAGE>
pay the employee an amount equal to (A) three times the sum of (i) his highest
base salary paid under the agreement and (ii) the higher of the most recent
bonus paid to the employee under the agreement or 50% of his base salary
immediately prior to such termination; plus (B) an amount in cash equal to the
value of any accrued but unpaid base salary, bonus and vacation pay. In
addition, the employee will continue to receive benefits for a period of three
years from the date of termination. In the event that the employee terminates
his employment by Casella following a change of control of Casella in which
specified events occur which affect the terms of the employee's employment, the
employee will receive the payments described in the preceding two sentences plus
an additional payment intended to compensate the employee for taxes payable in
connection with the severance payments. Mr. Cifor will also be entitled to
continue to receive his base salary until the first anniversary of the closing
of the merger even if he were to terminate his employment without cause during
such period.

    TERMINATION PAYMENTS.  In connection with the merger, Paul A. Garrett, vice
chairman of the KTI board, will receive a payment of approximately $1.2 million
in connection with his existing employment agreement with KTI, which will be
terminated.

    INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.  The merger agreement
provides that after the merger, Casella and the surviving corporation will
indemnify each present and former director, officer, employee and agent of KTI
and any of its subsidiaries against any costs and expenses incurred in
connection with any claim or action relating to matters existing or occurring at
or prior to the closing of the merger to the fullest extent that KTI would have
been permitted to do so under New Jersey law and KTI's charter and by-laws in
effect on January 12, 1999. In addition, Casella will also advance expenses as
incurred to the fullest extent permitted under applicable law, subject to the
conditions set forth in the merger agreement.

    For a period of six years after the closing of the merger, Casella will
maintain in effect a directors' and officers' liability insurance policy
covering those persons who are currently covered by KTI's directors' and
officers' liability insurance policy with coverage in an amount and scope at
least as favorable to these persons as KTI's existing coverage.

    The directors, officers and principal shareholders of KTI and Casella and
their associates have had in the past and may in the future have transactions in
the ordinary course of business with Casella or KTI and their subsidiaries and
affiliates. Any future transactions are expected to be on substantially the same
terms as those prevailing at the time for comparable transactions with
unaffiliated third parties.

    The Casella board, immediately following the merger, is expected to consist
of the following nine persons: Douglas R. Casella, John W. Casella, James W.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

    The following discussion addresses the material federal income tax
consequences of the merger that are generally applicable to holders of KTI
common stock exchanging their KTI common stock for Casella Class A common stock.
KTI shareholders should be aware that the federal income tax discussion set
forth below may not be applicable to certain classes of taxpayers, including,
for example, securities dealers and others that use a "mark-to-market" method of
accounting for federal income tax purposes, banks, insurance companies, tax
exempt organizations or trusts, foreign persons, persons who hold shares of KTI
common stock as part of a straddle or conversion transaction and persons who
acquired shares of KTI common stock pursuant to the exercise of employee stock
options or rights or otherwise as compensation. In addition, the following
discussion does not address the tax consequences of the merger under foreign,
state or local tax laws.

    KTI SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING THE APPLICABILITY AND
EFFECT OF FEDERAL, STATE, LOCAL AND OTHER TAX LAWS.

                                       46
<PAGE>
    Casella and KTI intend for the merger to be treated as a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code. McDermott,
Will & Emery, tax counsel to KTI, has rendered a tax opinion to KTI stating that
for federal income tax purposes the merger will be treated as a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code. The tax
opinion is not binding on the Internal Revenue Service, and there can be no
assurance that the IRS will not contest the conclusions expressed therein. The
tax opinion is based in part upon factual assumptions and representations made,
and certificates delivered, by Casella and KTI, which representations and
certificates McDermott, Will & Emery has assumed to be true, correct and
complete. If the representations or certificates are inaccurate, the tax opinion
could be adversely affected.

    The following summary constitutes the opinion of McDermott, Will & Emery and
sets forth anticipated material federal income tax consequences of the merger to
KTI shareholders. The tax treatment of each KTI shareholder will depend in part
upon that shareholder's particular situation. This summary is based on the
provisions of the Internal Revenue Code, the treasury regulations promulgated
thereunder and administrative and judicial interpretations thereof, all as in
effect as of the date hereof. These laws, regulations or interpretations may
differ at the time the merger is completed, and relevant facts also may differ.
Subject to the limitations and qualifications referred to herein and in the tax
opinion, filed as an exhibit to the registration statement of which this proxy
statement/ prospectus is a part. The merger will have the following federal
income tax consequences to KTI shareholders:

    - No gain or loss will be recognized by a KTI shareholder who receives
      solely Casella Class A common stock for shares of KTI common stock, except
      to the extent the shareholder receives cash in lieu of a fractional share
      interest in Casella Class A common stock;

    - The aggregate tax basis of the Casella Class A common stock received by a
      KTI shareholder will equal that shareholder's aggregate tax basis in the
      exchanged shares of KTI common stock;

    - The holding period of the Casella Class A common stock received by a KTI
      shareholder will include the holding period of the shares of exchanged KTI
      common stock, provided that these shares were held as a capital asset as
      of the date the merger was completed; and

    - A KTI shareholder who receives cash in lieu of a fractional share of
      Casella Class A common stock will be treated as having received the
      fractional share and then as having exchanged the fractional share for
      cash in a redemption by Casella subject to Section 302 of the Internal
      Revenue Code. This redemption generally will be treated as a sale of the
      fractional share. If the Casella Class A common stock represents a capital
      asset in the hands of the shareholder, the shareholder will generally
      recognize capital gain or loss on the redemption of the fractional share
      in an amount determined by the difference between the amount of cash
      received and the shareholder's tax basis in the fractional share, and any
      capital gain or loss will be a long-term capital gain or loss if the
      exchanged KTI common stock was held for more than one year. Long-term
      capital gain of a non-corporate stockholder is generally subject to a
      maximum capital gains rate of 20%.

    Unless an exemption applies under applicable law and regulations, the entity
which is designated to serve as exchange agent for KTI shares will be required
to withhold 31% of any cash payments to which a non-corporate shareholder or the
payee is entitled pursuant to the merger unless the shareholder or other payee
provides its social security number, employer identification number or
individual taxpayer identification number, and certifies that the number is
correct. Each shareholder and, if applicable, each payee must provide the
information and certification necessary to avoid backup withholding, unless an
applicable exemption exists and is established in a manner satisfactory to
Casella and the exchange agent.

                                       47
<PAGE>
ACCOUNTING TREATMENT

    The merger is expected to be accounted for using purchase accounting, with
Casella being deemed to have acquired KTI. Under the purchase method of
accounting, tangible and identifiable intangible assets acquired and liabilities
assumed are recorded at their estimated fair values. The excess of the purchase
price, including estimated fees and expenses related to the merger, over net
assets acquired is classified as goodwill.

REGULATORY APPROVALS

    Each of Casella and KTI has agreed to use all reasonable efforts to take or
cause to be taken all action and to do or cause to be done all things reasonably
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by the merger
agreement, including using all reasonable efforts to do the following:

    - cooperate in the preparation and filing of the registration statement of
      which this proxy statement/prospectus forms a part, and any amendments
      thereto, with the SEC, any filings that may be required under the
      Hart-Scott-Rodino Antitrust Improvements Act and any filings under similar
      merger notification laws or regulations of other governmental entities;
      and

    - obtain consents of all third parties and governmental entities necessary,
      proper or advisable for the consummation of the transactions contemplated
      by the merger agreement.

    ANTITRUST.  Under the Hart-Scott-Rodino Antitrust Improvements Act, and the
rules promulgated thereunder by the U.S. Federal Trade Commission, the merger
may not be consummated until notifications have been given and certain
information has been furnished to the Federal Trade Commission or the Antitrust
Division of the U.S. Department of Justice and the specified waiting period has
been satisfied. Casella and KTI were notified by the Federal Trade Commission on
February 23, 1999 that the waiting period has been satisfied.

    FILINGS WITH THE TREASURER OF THE STATE OF NEW JERSEY.  A certificate of
merger must be filed with the treasurer of the State of New Jersey to consummate
the merger.

    Casella and KTI are not aware of any other required regulatory approvals or
actions that are required prior to the parties' consummation of the merger.
Casella and KTI presently contemplate that if any additional governmental
approvals or actions are required that they will try to obtain them. There can
be no assurance, however, that any additional approvals or actions will be
obtained.

FEDERAL SECURITIES LAWS CONSEQUENCES

    The issuance of shares of Casella Class A common stock to KTI shareholders
in the merger and upon exercise of outstanding KTI options, warrants and
convertible notes after the merger has been registered under the Securities Act.
The shares of Casella Class A common stock issued in the merger may be traded
freely and without restriction by those KTI shareholders and holders of KTI
options or warrants not deemed to be "affiliates" of KTI as that term is defined
under the Securities Act. An affiliate of KTI is defined as a person who
directly, or indirectly through one or more intermediaries, controls, is
controlled by, or is under common control with, KTI. Any subsequent transfer of
shares received in the merger by any person who is an affiliate of KTI at the
time the merger is submitted for a vote of KTI shareholders will, under existing
law, require either:

    - the further registration under the Securities Act of the shares of Casella
      Class A common stock to be transferred;

    - compliance with Rule 145 under the Securities Act, which permits limited
      sales; or

    - the availability of another exemption from registration.

                                       48
<PAGE>
    The foregoing restrictions are expected to apply to the directors and
executive officers of KTI and the holders of 10% or more of the outstanding
shares of KTI common stock, if any, and to some relatives or the spouses of
these persons and any trusts, estates, corporations or other entities in which
the person has a 10% or greater beneficial or equity interest. Casella will give
stop transfer instructions to the transfer agent with respect to the Casella
Class A common stock to be received by persons subject to the restrictions
described above, and the certificates for the stock will be appropriately
legended.

STOCK EXCHANGE QUOTATION

    It is a condition to the merger that the shares of Casella Class A common
stock to be issued pursuant to the merger agreement be approved for listing on
the Nasdaq National Market, subject to official notice of issuance.

APPRAISAL RIGHTS

    The KTI shareholders are entitled to dissent and dissenters' rights under
Sections 14A:11-1 through 14A:11-11 of the New Jersey Business Corporation Act.
The following discussion summarizes all material provisions of the dissenters'
statute under New Jersey law. However, this discussion is not a complete
statement of the relevant provisions and is qualified by reference to the full
text of the dissenters' rights statute, which is attached as Annex C to this
proxy statement/prospectus. A person having a beneficial interest in shares of
KTI common stock that are held of record in the name of another person, for
example, a bank, broker or other nominee, must act promptly to cause the record
holder to follow the steps summarized below properly and in a timely manner if
such person wishes to exercise his or her dissenters' rights.

    THIS DISCUSSION AND ANNEX C SHOULD BE REVIEWED CAREFULLY BY ANY KTI
SHAREHOLDER WHO WISHES TO EXERCISE DISSENTERS' RIGHTS OR WHO WISHES TO PRESERVE
THE RIGHT TO DO SO, BECAUSE FAILURE TO COMPLY WITH ANY OF THE PROCEDURAL
REQUIREMENTS OF THE DISSENTERS' RIGHTS STATUTE COULD RESULT IN A LOSS OF THESE
RIGHTS.

    Under the dissenters' rights statute, each KTI shareholder electing to
dissent from the merger and demand payment of the fair value of his or her
shares of KTI common stock must file with KTI a written notice of dissent
stating that he or she intends to demand payment for his or her shares if the
merger is consummated. The written notice of dissent must be filed with KTI
before the vote of KTI shareholders on the merger. A KTI shareholder may dissent
only as to all of the shares he or she beneficially owns.

    Within ten days after the closing of the merger, KTI will give written
notice of the closing by certified mail to each KTI shareholder who filed a
written notice of dissent, except for any shareholder who subsequently voted for
the merger. Within 20 days after KTI mails this notice of the closing, a
dissenting shareholder may make written demand on KTI for payment of the fair
value of his or her shares.

    Within 20 days after demanding payment for his or her shares, a KTI
shareholder must submit any certificate(s) representing his or her shares to KTI
for notation that the payment demand has been made. The certificate(s) will then
be returned to the KTI shareholder. Ten days after the expiration of the 20 day
period during which a KTI shareholder may make a demand for payment, KTI will
mail to each dissenting KTI shareholder KTI's financial statements as of the
latest available date. KTI may accompany the mailing with a written offer to pay
each dissenting KTI shareholder a specified price deemed by KTI to be the fair
value of the shareholder's shares. An agreement by any dissenting shareholder
and KTI as to the fair value will not bind any other dissenting shareholders.
If, within 30 days after the expiration of the ten day period during which KTI
mails its financial statements, the fair value of the shares is agreed upon
between any dissenting shareholder and KTI, payment will be made

                                       49
<PAGE>
upon surrender of any certificate(s) representing dissenting shares. The "fair
value" is determined as of the day prior to the KTI shareholders meeting.

    If the fair value of the shares is not agreed upon within the 30 day period,
the dissenting shareholder may serve upon KTI a written demand that KTI commence
an action in the Superior Court of New Jersey for the determination of the fair
value of the shares. The demand must be served by the KTI shareholder not later
than 30 days after the expiration of the 30 day period in which the KTI
shareholder and KTI could not agree upon the fair value of the shares. The
action must be commenced by KTI not later than 30 days after receipt of the
demand. If KTI fails to commence the action within the 30 day period, a
dissenting KTI shareholder may do so in the name of KTI, not later than 60 days
after the expiration of the 30 day period in which KTI may commence the action.
KTI does not intend to commence an action for the determination of the fair
value of the shares upon the demand to do so by a dissenting KTI shareholder.

    All dissenting KTI shareholders except, those who have agreed with KTI upon
the fair value of the shares, must be made parties to the action. The court will
determine the fair value of the dissenting shares. The judgment will include
interest from the date of the dissenting KTI shareholder's demand for payment to
the day of payment, unless the court finds that the refusal of any dissenting
KTI shareholder to accept an offer of payment made by KTI was not made in good
faith. The court will determine and assess the reasonable expenses incurred by
the court appraiser, which will be apportioned by the court among the parties.
These expenses do not include reasonable fees or expenses of counsel or experts
employed by any party. However, the fees and expenses of such counsel or experts
may be assessed against KTI if the court finds that the offer of payment made by
KTI was not made in good faith or if no such offer was made.

    A KTI shareholder who makes a written demand for payment under the
dissenters' rights statute will cease to have any of the rights of a KTI
shareholder except the right to be paid the fair value of his or her shares. The
right of a KTI shareholder to be paid the fair value of his or her shares will
terminate for a number of reasons, including:

    - failure to submit any certificate(s) held for notation;

    - if the demand for payment is withdrawn with the written consent of KTI;

    - if the fair value of the shares is not agreed upon and no action for the
      determination of fair value by the Superior Court of New Jersey is
      commenced within the appropriate time period;

    - if the Superior Court of New Jersey determines that the KTI shareholder is
      not entitled to payment for his or her shares;

    - if the merger is abandoned; or

    - if a court having jurisdiction prohibits or sets aside the merger.

                              THE MERGER AGREEMENT

    THE FOLLOWING IS A SUMMARY OF ALL MATERIAL PROVISIONS OF THE MERGER
AGREEMENT. THE MERGER AGREEMENT, INCLUDING ALL AMENDMENTS THERETO, IS ATTACHED
AS ANNEX A AND IS INCORPORATED BY REFERENCE INTO THIS PROXY
STATEMENT/PROSPECTUS. YOU SHOULD READ THE MERGER AGREEMENT FOR A COMPLETE
UNDERSTANDING OF ITS TERMS.

STRUCTURE OF THE MERGER

    The merger agreement provides that, following the approval of the merger
agreement by KTI shareholders and the approval of the issuance of the shares
pursuant to the merger agreement by Casella stockholders and the satisfaction or
waiver of the other conditions to the merger, a wholly-owned subsidiary of
Casella will be merged with and into KTI. KTI will be the surviving corporation
and will become a direct, wholly-owned subsidiary of Casella.

CONSUMMATION OF THE MERGER

    It is expected that the closing contemplated by the merger agreement will
take place after all the conditions to the merger have been satisfied or waived,
which is expected to be prior to December 10, 1999.

MERGER CONSIDERATION

    At the closing of the merger, by virtue of the merger and without any action
on the part of any KTI shareholder, each share of KTI common stock issued and
outstanding immediately prior to the closing, except for shares owned by KTI as
treasury stock or owned by Casella, will be converted into the right to receive
0.51 of a share of Casella Class A common stock.

EXCHANGE OF STOCK CERTIFICATES

    As soon as practicable after the closing, we will cause an exchange agent to
deliver transmittal forms to each holder of record of KTI common stock to be
used in surrendering shares in exchange for shares of Casella Class A common
stock. No fractional shares of Casella Class A common stock will be issued in
the merger. Each holder of KTI common stock who otherwise would be entitled to
receive a fraction of a share of Casella Class A common stock in the merger will
be paid an amount in cash, without interest, equal to the applicable fraction
multiplied by the average of the closing prices for the Casella Class A common
stock over the ten trading days preceding the closing date of the merger.

    After receipt of the transmittal form, KTI shareholders should surrender
their certificates to the exchange agent. Each holder surrendering his or her
certificates will then receive a certificate representing the number of whole
shares of Casella Class A common stock to which the holder is entitled and a
check for the cash payable in lieu of a fractional share of Casella Class A
common stock. The transmittal forms will be accompanied by instructions
specifying other details of the exchange.

    KTI SHAREHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY RECEIVE A
     TRANSMITTAL FORM.

    After the closing of the merger, each certificate representing shares of KTI
common stock, until so exchanged, will be deemed, for all purposes, to evidence
the right to receive the number of shares of Casella Class A common stock into
which the shares of KTI common stock evidenced by the certificate have been
converted and the right to receive a cash payment, if any, in lieu of a
fractional share of Casella Class A common stock.

                                       51
<PAGE>
TREATMENT OF KTI COMMON STOCK OPTIONS AND WARRANTS

    STOCK OPTIONS.  At the closing of the merger, each outstanding option to
purchase shares of KTI common stock that is then outstanding and unexercised
will be assumed by Casella. Each option will continue to have, and be subject
to, the same terms and conditions set forth in the applicable stock option
agreement immediately prior to the effective time, except that each option will
be exercisable, or will become exercisable in accordance with its terms, for
that number of shares of Casella Class A common stock equal to the product of
multiplying (a) the number of shares of KTI common stock that were issuable upon
exercise of the option immediately prior to the closing of the merger by
(b) the exchange ratio. The exercise price per share of Casella Class A common
stock under the new option will be equal to the exercise price per share of KTI
common stock under the original option, divided by the exchange ratio.

    WARRANTS.  At the closing of the merger, each outstanding warrant to
purchase shares of KTI common stock, whether or not exercisable, will be assumed
by Casella. Each warrant will continue to have, and be subject to, the same
terms and conditions set forth in the applicable warrant immediately prior to
the closing of the merger, except that each warrant will be exercisable, or will
become exercisable in accordance with its terms, for that number of shares of
Casella Class A common stock equal to the product of the number of shares of KTI
common stock that were issuable upon exercise of the warrant immediately prior
to the closing of the merger multiplied by the exchange ratio. The exercise
price per share of Casella Class A common stock under the new warrant will be
equal to the exercise price per share of KTI common stock under the original
warrant, divided by the exchange ratio.

    KTI and Casella have each made customary representations and warranties to
the other in the merger agreement relating to, among other things:

    - their organization, the organization of their subsidiaries and similar
      corporate matters;

    The merger agreement may be terminated at any time prior to the closing of
the merger, whether before or after approval of the merger by the shareholders

    - mutual consent of KTI and Casella;

    - either KTI or Casella:

       - if the merger has not been consummated by December 15, 1999, provided
         that neither party may terminate if its breach is the reason for the
         failure of the merger to occur before that date;

       - if a court or a government entity has taken action to restrain or
         prohibit the merger;

       - if the required approval of the shareholders of KTI or Casella is not

                                       55

         merger agreement or the merger;

       - if, after receipt by KTI of an acquisition proposal, Casella asks the

         the merger and the KTI board fails to do so within 10 business days;

       - if the KTI board has recommended to the KTI shareholders the
         acquisition by a person other than Casella of more than 25% of the
         outstanding KTI common stock or more than 20% of KTI's assets;

       - if a tender offer or exchange offer for 25% or more of the outstanding
         KTI common stock is commenced by a person other than Casella and the
         KTI board recommends that KTI shareholders tender their shares; or

       - if for any reason KTI fails to call and hold the KTI shareholders
         meeting to approve the merger before December 15, 1999.

    If the merger agreement is validly terminated, the merger agreement will

and payment of expenses, and the termination will be without any liability on
the part of either party unless that party is in willful breach of the merger
agreement.

      the merger agreement.

STOCK OPTION AGREEMENT

    As an inducement and as a condition to enter into the merger agreement, KTI
and Casella entered into a stock option agreement, as amended on May 12, 1999,
whereby KTI granted Casella an option entitling Casella to purchase up to
2,769,331 shares of KTI common stock, representing approximately 19.9% of the
shares of KTI common stock outstanding as of the signing of the amendment to the
merger agreement, at an exercise price of $10.40 per share. The closing market
price of KTI common stock on May 12, 1999 was $11.125 per share. The option
granted may be exercised by Casella in whole or in part at any time after a
proposal for an alternative transaction, as defined in the merger agreement and
summarized below, involving KTI has been made, and one of the following events
has occurred on or after the making of the proposal:

    - the vote of KTI shareholders in favor of the merger has not been obtained
      at the KTI shareholders meeting;

    - the KTI board withdrew or modified its recommendations of the merger
      agreement or the merger;

    - the KTI board failed to confirm its recommendation of the merger agreement
      or the merger within ten business days after a written request by Casella
      to do so;

    - the KTI board recommended to KTI shareholders an alternative transaction;

    - a tender offer or exchange offer of 25% or more of the outstanding shares
      of KTI has been commenced, other than by Casella, and the KTI board
      recommended that KTI shareholders tender their shares; or

    - for any reason KTI failed to call and hold its special meeting of
      shareholders by December 15, 1999 and KTI is not at that time otherwise
      entitled to terminate the merger agreement because of a breach by Casella.

        An "alternative transaction" is defined in the merger agreement as:

    - the acquisition by a third party of more than 25% of the outstanding
      shares of KTI common stock;

                                       57
<PAGE>
    - a merger or other business combination involving KTI in which a third
      party acquires more than 25% of the outstanding shares of KTI common stock
      or of the surviving entity;

    - any other transaction in which a third party acquires assets of KTI having
      a fair market value of more than 20% of the value of all the assets of
      KTI; or

    - any public announcement by a third party of a proposal, plan or intention
      to do any of the foregoing or an agreement to engage in any of the
      foregoing.

    If at any time the option becomes exercisable, Casella may elect, in lieu of
exercising its option to purchase KTI common stock, to receive a cash amount
equal to the excess of the exercise price of the option over the higher of
(a) the highest price per share of KTI common stock paid by any person pursuant
to a superior proposal, or (b) the closing price of KTI common stock on the
Nasdaq Stock Market on the last trading day immediately prior to the date of the
election.

    The stock option agreement also contains provisions relating to, among other
things, representations and warranties of KTI, registration rights of Casella
and specific performance of the stock option agreement.

    Notwithstanding the foregoing, Casella's profit on the exercise of the
option may not exceed $11.0 million after taking into account the exercise price
of the option and the amounts payable to Casella as a termination fee pursuant
to the merger agreement.

                                 THE COMPANIES

CASELLA

COMPANY OVERVIEW

    Casella Waste Systems, Inc. is a regional, integrated, non-hazardous solid
waste services company that provides collection, transfer, disposal and
recycling services in Vermont, New Hampshire, Maine, Massachusetts, upstate New
York and northern Pennsylvania. As of September 1, 1999, Casella owned and/or
operated five Subtitle D landfills, two landfills permitted to accept
construction and demolition materials, 54 transfer stations, 24 recycling
processing facilities, and 40 solid and liquid waste collection divisions, which
collectively served over 500,000 commercial, industrial and residential
customers. Casella was founded in 1975 as a single-truck operation in Rutland,
Vermont and subsequently expanded its operations throughout the state of
Vermont. In 1993, Casella initiated an acquisition strategy to take advantage of
anticipated reductions in available landfill capacity in Vermont and surrounding
states due to increasing environmental regulation and other market forces
driving consolidation in the solid waste industry. From May 1, 1994 through
April 30, 1999, Casella acquired ownership or long-term operating rights to 132
solid waste businesses, including 7 landfills, and between May 1, 1999 and July
31, 1999 Casella acquired an additional 13 such businesses.

    During the fiscal year ended April 30, 1999, Casella expanded and
strengthened its market presence throughout its three geographic regions by
acquiring 55 solid and liquid waste management businesses totaling approximately
$54.5 million in revenues, including the following:

    On September 4, 1998 Casella completed a merger with Hakes C & D Disposal,
Inc. This facility is a permitted landfill in western New York State designed to
accept construction and demolition material. As of July 15, 1999 the facility
was under construction and had not begun accepting waste. Casella believes this
facility will allow it to realize the financial and operational benefits of
disposing of construction and demolition debris collected by its own operations
in its own facility in a key market for Casella.

    On October 29, 1998, Casella completed a merger with Waste Stream Inc., B&C
Sanitation Corporation, North Country Trucking, Inc., Better Bedding Corp., R.A.
Bronson, Inc., BBC LLC, NTC LLC and Grasslands, Inc., (together, "Waste
Stream"), which provide solid waste and recycling collection services in
northern New York State. Casella believes the acquisition of Waste Stream
further strengthens Casella's market position in upstate New York.

    On December 23, 1998, Casella completed a merger with Northern Sanitation,
Inc and Northern Properties Corp. of Plattsburgh, Inc. (together, "Northern
Sanitation"), a solid waste collection company in Clinton County, New York.
Casella believes the proximity of Northern Sanitation to Casella's Clinton
County landfill gives it a stronger market presence in that region.

    On April 30, 1999 Casella completed a merger with Natural Environmental,
Inc., Schultz Landfill, Inc. and Blasdell Development Group, Inc. (together,
"NEI"), a collection, transfer and construction & demolition debris disposal
company serving the Buffalo, New York region. Also on April 30, 1999, Casella
completed a merger with Westfield Disposal Service, Inc. and Portland C & D
Landfill, Inc. (together, "Westfield Disposal"), a collection company, transfer
station, and construction and demolition debris landfill serving Chautauqua
County, New York and Erie, Pennsylvania. Casella believes that these
acquisitions provide Casella with a new growth platform in western New York and
expand geographically Casella's existing operations in its Western Region.

    Since the end of Casella's 1999 fiscal year on April 30, 1999, Casella
entered the eastern Massachusetts market with the acquisition of Resource Waste
Systems, Inc., Resource Recovery of Cape Cod, Inc., and Resource Transfer, Inc.
(collectively, "Resource Waste Systems, Inc."), which provide solid waste
collection and transfer services, and construction and demolition debris
processing

                                       59
<PAGE>
in eastern Massachusetts. Casella believes that the acquisition of Resource
Waste Systems provides Casella with a new growth platform in a market contiguous
to its existing markets, particularly when matched with the assets and
operations in southern Maine expected to be acquired in the merger with KTI.

SERVICE AREA

    Casella is managed on a decentralized basis, with its operations divided
into three geographic regions: the Central, Eastern and Western regions. These
three regions are further divided into divisions organized around smaller market
areas, known as "waste sheds", each of which contains the complete cycle of
activities in the solid waste service process, from collection to transfer
stations to disposal. The following are Casella's three geographic regions that
comprise Casella's service area:

    CENTRAL REGION

    The Central Region consists of Vermont, portions of New Hampshire and
eastern upstate New York. Casella was founded in 1975 in Rutland, Vermont, and
has continued to grow its market presence in the Central Region. The portion of
upstate New York within Casella's Central Region as of July 15, 1999 extends
from Interstate 90 north to the Canadian border and from the Vermont border west
to Interstate 81 and the eastern shore of Lake Ontario. Casella owns and
operates Subtitle D landfills in Bethlehem, New Hampshire; Coventry, Vermont;
and, through a 25-year capital lease, operates the Clinton County landfill
located in Schuyler Falls, New York. In addition, Casella operated 18 collection
operations and 27 transfer stations in the Central Region as of July 15, 1999.
See "--Legal Proceedings."

    EASTERN REGION

    Casella's Eastern Region consists of the State of Maine and southeastern New
Hampshire. Casella established a market presence in Maine through the
acquisition of the Sawyer Companies in January 1996. Casella owns the SERF
landfill located in Hampden, Maine, which disposes of ash, construction and
demolition debris, special waste and front end processing residue primarily from
throughout the State of Maine. In addition, at July 15, 1999 Casella operated
six collection operations and 12 transfer stations, and collected solid waste
from commercial, industrial and residential customers in the Eastern Region.
Casella's waste tire processing facility, located in Eliot, Maine, has the
capacity to process approximately 3.5 million tires per year and generates tire
derived fuel, which Casella sells to paper mills for consumption as a
supplemental energy source for boiler fuel.

    Unlike the other states in Casella's existing market area, Maine has an
aggressive incineration program and Casella believes that approximately 80% of
the waste shed in Casella's market area is disposed of through incineration.
However, Casella believes that approximately 35% of the tonnage delivered to
incinerators is returned to landfills as ash and front end processing residue,
and Casella is the largest disposer of incinerated waste material in Maine.

    WESTERN REGION

    The Western Region is comprised of the south central, western and southern
tier of upstate New York (including Ithaca, Elmira, Horsehead, Corning and
Watkins Glen) and the northern tier of Pennsylvania. Through the acquisition of
the Superior Disposal Services companies in January 1997, Casella established
its market presence in the Western Region. At July 15, 1999 Casella operated 15
transfer stations and 14 collection operations, and collected solid waste from
commercial, industrial and residential customers. During fiscal 1999 Casella
acquired a Subtitle D permitted landfill, the Hyland facility, in Angelica, New
York, which serves the western upstate portion of our New York waste shed.

                                       60

See "--Legal Proceedings". Casella also acquired two landfills in fiscal 1999
permitted to accept construction and demolition materials, the Hakes and
Portland facilities.

OPERATIONS

    Casella's operations include the ownership and/or operation of landfills,
solid waste collection services, transfer stations, recycling services,
septic/liquid waste operations, and tire processing and other services.

    LANDFILLS

    Casella currently owns four Subtitle D landfill operations and operates a
fifth Subtitle D landfill under a 25-year lease arrangement with a county. All
of Casella's operating Subtitle D landfills include leachate collection systems,
groundwater monitoring systems and, where required, active methane gas
extraction and recovery systems. In addition to these landfills Casella owns two
landfills permitted to accept only construction and demolition materials. These
types typically, depending on the state in which they are located, are
constructed in accordance with lower environmental standards than Subtitle D
landfills, reflecting the inert nature of the materials deposited in them.

    During the fiscal year ended April 30, 1999, approximately 71% of the waste
volumes received by Casella's landfills were from internal sources such as
Casella's hauling divisions or transfer stations.

    The following table provides certain information regarding the landfills
that Casella operates. All of such information is provided as of July 15, 1999.

    Maine, where the site is located, has not issued the required construction
    permits for work to begin on the expansion. Casella has brought a legal
    action against the town to set aside the town's efforts to block the
    expansion. See "--Legal Proceedings." The remaining 200,000 tons meets all
    state and local requirements.

    SERF.  The SERF landfill is located in Hampden, Maine. The SERF landfill
processes ash, special waste and front end processing residue (i.e., glass and
other material segregated and disposed of separately from solid waste prior to
incineration), for the Penobscot Energy Recovery Corporation's incinerator under
a contract expiring in 2003. As noted above, the Town of Hampden has delayed the
construction of the newest permitted cell of this site by failing to issue a
construction permit in a timely manner. Although Casella has initiated legal
proceedings in an effort to prevent the Town from continuing to obstruct
expansion, there can be no assurance Casella will prevail. See "--Legal
Proceedings." The Penobscot Energy Recovery Corporation's incinerator is owned
by a limited partnership in which KTI holds a 70.36% ownership interest.

    NCES.  The NCES landfill, located in Bethlehem, New Hampshire, serves the
northern and central New Hampshire waste sheds and portions of the Maine and
Vermont waste sheds. The Town of Bethlehem has adopted a zoning ordinance which
precludes the `expansion of any existing landfills'. Casella has contested this
ordinance vigorously. See "--Legal Proceedings" for details of these
proceedings.

    WASTE USA.  The Waste USA landfill is located in Coventry, Vermont and
serves the northern two-thirds of Vermont.

    CLINTON COUNTY.  The Clinton County landfill, located in Schuyler Falls, New
York, is leased by Casella from Clinton County, New York pursuant to a 25-year
capital lease which expires in 2021. Under the lease, Casella is generally
obligated to expand the landfill at its own cost. Under the terms of the lease,
the Clinton County landfill cannot receive waste from certain geographic regions
in New York. The facility has a permitted capacity of 175,000 tons per year.
Under the lease, Casella is responsible for operating the landfill in compliance
with all applicable environmental laws, including without limitation, possessing
and complying with all necessary permits and licenses. Casella must indemnify
the County for all liabilities resulting from any violations of those laws
(exclusive of violations based on pre-existing conditions, which remain the
responsibility of the County and with respect to which the County indemnifies
Casella). In addition, Casella is responsible for the composition of waste
deposited at the landfill during the lease term, regardless of Casella's
knowledge or monitoring efforts. The lease gives Casella full physical and
managerial control over an unlined landfill on the site, which was operated by
Casella from July 1996 through July 1997, while the lined landfill was under
construction. Clinton County has agreed to indemnify Casella for environmental
liabilities arising from the unlined landfill prior to its operation by Casella.
Casella was responsible for the closure of the unlined landfill, and
post-closure care is the responsibility of the County. Casella completed the
closure and capping activities at this landfill in September 1997. Casella is
also responsible for performing certain cleanup work with respect to the unlined
landfill and has agreed to absorb the resulting costs subject to satisfactory
construction of the lined portion. Casella is responsible for both closure and
post-closure care with respect to the lined landfill upon exhaustion of the
corresponding airspace.

    HYLAND.  The Hyland landfill, located in Angelica, New York in Allegany
County, serves Casella's Western Region. The Town of Angelica has adopted a
local ordinance seeking to restrict the manner in which Casella may operate or
expand this facility.

    HAKES.  This facility is located in Campbell, New York. The first cell of
this facility is currently under construction and is projected to be open in
November 1999.

    PORTLAND.  This facility, acquired on April 30, 1999 as part of the
Westfield Disposal merger, is located in Portland, New York. The facility is
currently under construction and is projected to re-open in October 1999.

                                       62
<PAGE>
    Casella also owns and/or operated five unlined landfills, which are not
currently in operation. All of these landfills have been closed and
environmentally capped by Casella. One of the unlined landfills, a municipal
landfill which is adjacent to the Subtitle D Clinton County landfill being
operated by Casella, was operated by Casella from July 1996 through July 1997.
Casella completed the closure and capping activities at this landfill in
September 1997, and is indemnified by Clinton County for environmental
liabilities arising from such landfill prior to Casella's operation.

    Casella regularly monitors the available permitted in-place disposal
capacity at each of its landfills and evaluates whether to seek to expand this
capacity. In making this evaluation, Casella considers various factors,
including the volume of solid waste projected to be disposed of at the landfill,
the size of the unpermitted capacity included in the landfill, the likelihood
that Casella will be successful in obtaining the approvals and permits required
for the expansion and the costs that would be involved in developing the
expanded capacity. Casella also considers on an ongoing basis the extent to
which it is advisable, in light of changing market conditions and/or regulatory
requirements, to seek to expand or change the permitted waste streams at a
particular landfill or to seek other permit modifications.

    The permitting process is lengthy, difficult and expensive, and is subject
to substantial uncertainty and there can be no assurance that any such permits
or expansion requests will be granted. Often, even when permits are granted,
they are not granted until the landfill's remaining capacity is very low. There
can be no assurance that Casella will be able to add additional disposal
capacity when needed or, if added, that such capacity can be added on
satisfactory terms or at its landfills where expansion is most immediately
needed. If Casella is not able to add additional disposal capacity when and
where needed, it may need to dispose of its collected waste at its other
landfills or at landfills owned by others. Such a circumstance could have a
material adverse effect on Casella's business, financial condition and results
of operations.

    Once the permitted capacity of a particular landfill is reached, the
landfill must be closed and capped if additional capacity is not authorized.
Casella establishes reserves for the estimated costs associated with such
closure and post-closure costs over the anticipated useful life of such
landfill.

    SOLID WASTE COLLECTION

    Casella's 38 solid waste collection divisions served over 500,000
commercial, industrial and residential customers at September 1, 1999. During
fiscal 1999, approximately 49% of the solid waste collected by Casella was
delivered for disposal at its landfills. Casella's collection operations are
generally conducted within a 125-mile radius of its landfills. A majority of
Casella's commercial and industrial collection services are performed under
one-to-three-year service agreements, and fees are determined by such factors as
collection frequency, type of equipment and containers furnished, the type,
volume and weight of the solid waste collected, the distance to the disposal or
processing facility and the cost of disposal or processing. Casella's
residential collection and disposal services are performed either on a
subscription basis (i.e., with no underlying contract) with individuals, or
under contracts with municipalities, homeowners associations, apartment owners
or mobile home park operators.

    TRANSFER STATION SERVICES

    Casella operated 54 transfer stations as of September 1, 1999, of which 27
were owned by Casella and 27 were operated under contracts with municipalities.
The transfer stations receive, compact and transfer solid waste collected
primarily from Casella's various collection operations to larger company-owned
vehicles for transport to landfills. Casella believes that transfer stations
benefit Casella by: (i) increasing the size of the waste shed which has access
to Casella's landfills; (ii) reducing costs by improving utilization of
collection personnel and equipment; and (iii) building relationships with

                                       63
<PAGE>
municipalities that may lead to future business opportunities, including
privatization of the municipality's waste management services.

    RECYCLING SERVICES

    Casella has sought to position itself to provide recycling services to
customers who are willing to pay for the cost of the recycling service.
Depending on the terms of the individual customer contracts and the level of
recovered material commodity prices, the proceeds generated from reselling the
recycled materials are occasionally shared between Casella and its customers. In
addition, Casella has adopted a pricing strategy of charging collection and
processing fees for recycling volume collected from its customers. By
structuring its recycling service program in this way, Casella has sought to
reduce its exposure to commodity price risk with respect to the recycled
materials.

    As of September 1, 1999 Casella operated 24 recycling processing facilities.
Casella processes more than 20 classes of recyclable materials originating from
the municipal solid waste stream, including cardboard, office paper, containers
and bottles. Casella's recycling operations are concentrated principally in
Vermont, as the public sector in other states in Casella's service area has
generally taken primary responsibility for recycling efforts. At September 1,
1999, Casella employed one commodity sales manager to develop end markets, and
had 71 employees in the recycling facilities to support the processing of
approximately 70,000 tons of recyclable materials annually.

    WASTE TIRE PROCESSING AND OTHER SERVICES

    Casella's waste tire processing facility, located in Eliot, Maine, has the
capacity to process approximately 3.5 million tires per year and generates tire
derived fuel, which Casella sells to paper mills for consumption as a
supplemental energy source for boiler fuel. In June 1997, Casella was selected
by the State of Maine to process an estimated 2.5 million tires over an 18-month
period. Because of continuing losses in Casella's waste tire processing
facility, in the fourth quarter of fiscal 1998 Casella wrote-down the carrying
value of the tire processing facility in the amount of $971,000. See "Casella
Management's Discussion and Analysis of Financial Condition and Results of
Operations" and Note 2(j) of Notes to Consolidated Financial Statements.

    Casella's other services include two septic/liquid waste operations, located
in Casella's Central Region.

COMPETITION

    The solid waste services industry is highly competitive, undergoing a period
of consolidation, and requires substantial labor and capital resources. Casella
competes with numerous solid waste management companies, many of which are
significantly larger and have greater access to capital and greater financial,
marketing or technical resources than Casella. Certain of Casella's competitors
are large national companies that may be able to achieve greater economies of
scale than Casella. Casella also competes with a number of regional and local
companies. In addition, Casella competes with operators of alternative disposal
facilities, including incinerators, and with certain municipalities, counties
and districts that operate their own solid waste collection and disposal
facilities. Public sector facilities may have certain advantages over Casella
due to the availability of user fees, charges or tax revenues and the greater
availability to them of tax-exempt financing. In addition, recycling and other
waste reduction programs may reduce the volume of waste deposited in landfills.

    Casella competes for collection and disposal volume primarily on the basis
of the price and quality of its services. From time to time, competitors may
reduce the price of their services in an effort to expand market share or to win
a competitively bid municipal contract. These practices may also lead to reduced
pricing for Casella's services or the loss of business.

                                       64
<PAGE>
    Competition exists within the industry not only for collection,
transportation and disposal volume, but also for acquisition candidates. Casella
generally competes for acquisition candidates with publicly owned regional and
national waste management companies.

MARKETING AND SALES

    Casella has a coordinated marketing and sales strategy which is formulated
at the corporate level and implemented at the divisional level. Casella markets
its services locally through division managers and direct sales representatives
who focus on commercial, industrial, municipal and residential customers. As of
September 1, 1999, Casella had 39 division managers, 4 sales managers and 43
direct sales representatives. Casella also obtains new customers from referral
sources, its general reputation and local market print advertising. Leads are
also developed from new building permits, business licenses and other public
records. Additionally, each division generally advertises in the yellow pages
and other local business print media that cover its service area.

    Maintenance of a local presence and identity is an important aspect of
Casella's marketing plan, and many of Casella's managers are involved in local
governmental, civic and business organizations. Casella's name and logo, or,
where appropriate, that of Casella's divisional operations, are displayed on all
company containers and trucks. Additionally, Casella attends and makes
presentations at municipal and state conferences and advertises in governmental
associations' membership publications.

    Casella markets its commercial, industrial and municipal services through
its sales representatives who visit customers on a regular basis and make sales
calls to potential new customers. These sales representatives receive a
significant portion of their compensation based upon meeting certain incentive
targets. Casella emphasizes providing quality services and customer satisfaction
and retention, and believes that its focus on quality service will help retain
existing and attract additional customers.

EMPLOYEES

    At September 1, 1999, Casella employed approximately 1,504 full-time
employees, including approximately 117 professionals or managers, approximately
1,173 employees involved in collection, transfer and disposal operations, and
approximately 214 sales, clerical, data processing or other administrative
employees.

    On October 30, 1998, Casella merged with Waste Stream. Prior to the merger
the employees of Waste Stream's Malone, New York location had voted in favor of
representation by Chauffeurs, Teamsters, Warehousemen and Helpers Union
("Teamsters") Local #687, but at that time they did not have an approved,
ratified contract with Waste Stream. Negotiations between the represented
employees and Casella are ongoing.

    On May 11, 1999 a petition for representation was filed with the National
Labor Relations Board by Teamsters Local #597 on Casella Transportation, Inc. On
June 25, 1999 the employees of Casella Transportation, Inc. rejected the measure
to select union representation.

    On July 1, 1999 Casella acquired Resource Waste Systems, Inc. The drivers at
Resource Waste Systems, Inc. are represented by the National Industries Union
Local #88 and the Teamsters Local #379.

    Through a labor utilization agreement, Casella utilizes the services of
Clinton County employees at the Clinton County landfill. The Clinton County
employees are represented by a labor union.

    Casella is aware of no other organizational efforts among its employees.
Casella believes that its relations with its employees are good.

                                       65
<PAGE>
RISK MANAGEMENT, INSURANCE AND PERFORMANCE OR SURETY BONDS

    Casella actively maintains environmental and other risk management programs
which it believes are appropriate for its business. Casella's environmental risk
management program includes evaluating existing facilities, as well as potential
acquisitions, for environmental law compliance and operating procedures. Casella
also maintains a worker safety program which encourages safe practices in the
workplace. Operating practices at all company operations are intended to reduce
the possibility of environmental contamination and litigation.

    Casella carries a range of insurance intended to protect its assets and
operations, including a commercial general liability policy and a property
damage policy. A partially or completely uninsured claim against Casella
(including liabilities associated with cleanup or remediation at its own
facilities) if successful and of sufficient magnitude, could have a material
adverse effect on Casella's business, financial condition and results of
operations. Any future difficulty in obtaining insurance could also impair
Casella's ability to secure future contracts, which may be conditioned upon the
availability of adequate insurance coverage.

    Effective July 1, 1999, Casella established a captive insurance company,
"Casella Insurance Company", through which it is self-insured for Workman's
Compensation coverage. Casella's maximum exposure under this plan is $250,000
per individual event, $2.7 million total, after which reinsurance takes effect
and limits Casella's exposure.

    Municipal solid waste collection contracts and landfill closure obligations
may require performance or surety bonds, letters of credit or other means of
financial assurance to secure contractual performance. Casella has not
experienced difficulty in obtaining performance or surety bonds or letters of
credit. If Casella were unable to obtain performance or surety bonds or letters
of credit in sufficient amounts or at acceptable rates, it may be precluded from
entering into additional municipal solid waste collection contracts or obtaining
or retaining landfill operating permits.

REGULATION

INTRODUCTION

    Casella is subject to extensive and evolving Federal, state and local
environmental laws and regulations which have become increasingly stringent in
recent years. The environmental regulations affecting Casella are administered
by the EPA and other Federal, state and local environmental, zoning, health and
safety agencies. Casella believes that it is currently in substantial compliance
with applicable Federal, state and local environmental laws, permits, orders and
regulations, and it does not currently anticipate any material environmental
costs to bring its operations into compliance (although there can be no
assurance in this regard). Casella anticipates there will continue to be
increased regulation, legislation and regulatory enforcement actions related to
the solid waste services industry. As a result, Casella attempts to anticipate
future regulatory requirements and to plan accordingly to remain in compliance
with the regulatory framework.

    In order to transport solid waste, it is necessary for Casella to possess
and comply with one or more permits from state or local agencies. These permits
also must be periodically renewed and may be modified or revoked by the issuing
agency.

    The principal Federal, state and local statutes and regulations applicable
to Casella's various operations are as follows:

THE RESOURCE CONSERVATION AND RECOVERY ACT OF 1976 ("RCRA")

    RCRA regulates the generation, treatment, storage, handling, transportation
and disposal of solid waste and requires states to develop programs to ensure
the safe disposal of solid waste. RCRA divides solid waste into two groups,
hazardous and nonhazardous. Wastes are generally classified as hazardous if they
(i) either (a) are specifically included on a list of hazardous wastes, or (b)
exhibit certain

                                       66
<PAGE>
characteristics defined as hazardous; and (ii) are not specifically designated
as nonhazardous. Wastes classified as hazardous under RCRA are subject to much
stricter regulation than wastes classified as nonhazardous, and businesses that
deal with hazardous waste are subject to regulatory obligations in addition to
those imposed on handlers of nonhazardous waste.

    Among the wastes that are specifically designated as nonhazardous are
household waste and "special" waste, including items such as petroleum
contaminated soils, asbestos, foundry sand, shredder fluff and most nonhazardous
industrial waste products.

    The EPA regulations issued under Subtitle C of RCRA impose a comprehensive
"cradle to grave" system for tracking the generation, transportation, treatment,
storage and disposal of hazardous wastes. The Subtitle C Regulations impose
obligations on generators, transporters and disposers of hazardous wastes, and
require permits that are costly to obtain and maintain for sites where such
material is treated, stored or disposed. Subtitle C requirements include
detailed operating, inspection, training and emergency preparedness and response
standards, as well as requirements for manifesting, record keeping and
reporting, corrective action, facility closure, post-closure and financial
responsibility. Most states have promulgated regulations modeled on some or all
of the Subtitle C provisions issued by the EPA. Some state regulations impose
different, additional obligations.

    Casella is currently not involved with transportation or disposal of
hazardous substances (as defined in CERCLA) in concentrations or volumes that
would classify those materials as hazardous wastes. However, Casella has
transported hazardous substances in the past and very likely will remain
involved with hazardous substance transportation and disposal in the future to
the extent that materials defined as hazardous substances under CERCLA are
present in consumer goods and in the waste streams of its customers.

    In October 1991, the EPA adopted the Subtitle D Regulations governing solid
waste landfills. The Subtitle D Regulations, which generally became effective in
October 1993, include location restrictions, facility design standards,
operating criteria, closure and post-closure requirements, financial assurance
requirements, groundwater monitoring requirements, groundwater remediation
standards and corrective action requirements. In addition, the Subtitle D
Regulations require that new landfill sites meet more stringent liner design
criteria (typically, composite soil and synthetic liners or two or more
synthetic liners) intended to keep leachate out of groundwater and have
extensive collection systems to carry away leachate for treatment prior to
disposal. Groundwater monitoring wells must also be installed at virtually all
landfills to monitor groundwater quality and, indirectly, the effectiveness of
the leachate collection system. The Subtitle D Regulations also require, where
certain regulatory thresholds are exceeded, that facility owners or operators
control emissions of methane gas generated at landfills in a manner intended to
protect human health and the environment. Each state is required to revise its
landfill regulations to meet these requirements or such requirements will be
automatically imposed by the EPA upon landfill owners and operators in that
state. Each state is also required to adopt and implement a permit program or
other appropriate system to ensure that landfills within the state comply with
the Subtitle D Regulations criteria. Various states in which Casella operates or
in which it may operate in the future have adopted regulations or programs as
stringent as, or more stringent than, the Subtitle D Regulations.

THE FEDERAL WATER POLLUTION CONTROL ACT OF 1972

    The Federal Water Pollution Control Act of 1972, as amended ("Clean Water
Act"), regulates the discharge of pollutants from a variety of sources,
including solid waste disposal sites and transfer stations, into waters of the
United States. If run-off from Casella's transfer stations or if run-off or
collected leachate from Casella's owned or operated landfills is discharged into
streams, rivers or other surface waters, the Clean Water Act would require
Casella to apply for and obtain a discharge permit, conduct sampling and
monitoring and, under certain circumstances, reduce the quantity of pollutants
in such discharge. Also, virtually all landfills are required to comply with the
EPA's storm water

                                       67
<PAGE>
regulations issued in November 1990, which are designed to prevent contaminated
landfill storm water runoff from flowing into surface waters. Casella believes
that its facilities are in compliance in all material respects with Clean Water
Act requirements.

THE COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION, AND LIABILITY ACT OF
  1980

    CERCLA established a regulatory and remedial program intended to provide for
the investigation and cleanup of facilities where or from which a release of any
hazardous substance into the environment has occurred or is threatened. CERCLA's
primary mechanism for remedying such problems is to impose strict joint and
several liability for cleanup of facilities on current owners and operators of
the site, former owners and operators of the site at the time of the disposal of
the hazardous substances, as well as the generators of the hazardous substances
and the transporters who arranged for disposal or transportation of the
hazardous substances. In addition, CERCLA also imposes liability for the cost of
evaluating and remedying any damage done to natural resources. The costs of
CERCLA investigation and cleanup can be very substantial. Liability under CERCLA
does not depend upon the existence or disposal of "hazardous waste" as defined
by RCRA, but can also be founded upon the existence of even very small amounts
of the more than 700 "hazardous substances" listed by the EPA, many of which can
be found in household waste. In addition, the definition of "hazardous
substances" in CERCLA incorporates substances designated as hazardous or toxic
under the federal Clean Water Act, Clear Air Act and Toxic Substances Control
Act. If Casella were found to be a responsible party for a CERCLA cleanup, the
enforcing agency could hold Casella, or any other generator, transporter or the
owner or operator of the contaminated facility, responsible for all
investigative and remedial costs even if others may also be liable. CERCLA also
authorizes the imposition of a lien in favor of the United States upon all real
property subject to, or affected by, a remedial action for all costs for which a
party is liable. CERCLA provides a responsible party with the right to bring a
contribution action against other responsible parties for their allocable shares
of investigative and remedial costs. Casella's ability to get others to
reimburse it for their allocable shares of such costs would be limited by
Casella's ability to find other responsible parties and prove the extent of
their responsibility and by the financial resources of such other parties.

THE CLEAN AIR ACT

    The Clean Air Act generally, through state implementation of Federal
requirements, regulates emissions of air pollutants from certain landfills based
upon the date of the landfill construction and volume per year of emissions of
regulated pollutants. The EPA has promulgated new source performance standards
regulating air emissions of certain regulated pollutants (methane and non-
methane organic compounds) from municipal solid waste landfills. Landfills
located in areas that do not comply with certain requirements of the Clean Air
Act may be subject to even more extensive air pollution controls and emission
limitations. In addition, the EPA has issued standards regulating the disposal
of asbestos-containing materials.

    All of the Federal statutes described above contain provisions authorizing,
under certain circumstances, the institution of lawsuits by private citizens to
enforce the provisions of the statutes. In addition to a penalty award to the
United States, some of those statutes authorize an award of attorney's fees to
parties successfully advancing such an action.

THE OCCUPATIONAL SAFETY AND HEALTH ACT OF 1970 ("OSHA")

    OSHA establishes employer responsibilities and authorizes the promulgation
by the Occupational Safety and Health Administration of occupational health and
safety standards, including the obligation to maintain a workplace free of
recognized hazards likely to cause death or serious injury, to comply with
adopted worker protection standards, to maintain certain records, to provide
workers with required disclosures and to implement certain health and safety
training programs. Various of those promulgated standards may apply to Casella's
operations, including those standards concerning notices

                                       68
<PAGE>
of hazards, safety in excavation and demolition work, the handling of asbestos
and asbestos-containing materials, and worker training and emergency response
programs.

STATE AND LOCAL REGULATIONS

    Each state in which Casella now operates or may operate in the future has
laws and regulations governing the generation, storage, treatment, handling,
transportation and disposal of solid waste, water and air pollution and, in most
cases, the siting, design, operation, maintenance, closure and post-closure
maintenance of landfills and transfer stations. In addition, many states have
adopted statutes comparable to, and in some cases more stringent than, CERCLA.
These statutes impose requirements for investigation and cleanup of contaminated
sites and liability for costs and damages associated with such sites, and some
provide for the imposition of liens on property owned by responsible parties.
Some of those liens may take priority over previously filed instruments.
Furthermore, many municipalities also have local ordinances, laws and
regulations affecting company operations. These include zoning and health
measures that limit solid waste management activities to specified sites or
conduct, flow control provisions that direct the delivery of solid wastes to
specific facilities or to facilities in specific areas, laws that grant the
right to establish franchises for collection services and then put out for bid
the right to provide collection services, and bans or other restrictions on the
movement of solid wastes into a municipality.

    Certain permits and approvals may limit the types of waste that may be
accepted at a landfill or the quantity of waste that may be accepted at a
landfill during a given time period. In addition, certain permits and approvals,
as well as certain state and local regulations, may limit a landfill to
accepting waste that originates from specified geographic areas or seek to
restrict the importation of out-of-state waste or otherwise discriminate against
out-of-state waste. Generally, restrictions on importing out-of-state waste have
not withstood judicial challenge. However, from time to time Federal legislation
is proposed which would allow individual states to prohibit the disposal of
out-of-state waste or to limit the amount of out-of-state waste that could be
imported for disposal and would require states, under certain circumstances, to
reduce the amounts of waste exported to other states. Although such legislation
has not been passed by Congress, if this or similar legislation is enacted,
states in which Casella operates landfills could limit or prohibit the
importation of out-of-state waste. Such state actions could materially adversely
affect the business, financial condition and results of operations of landfills
within those states that receive a significant portion of waste originating from
out-of-state.

    In addition, certain states and localities may for economic or other reasons
restrict the export of waste from their jurisdiction or require that a specified
amount of waste be disposed of at facilities within their jurisdiction. In 1994,
the U.S. Supreme Court held unconstitutional, and therefore invalid, a local
ordinance that sought to impose flow controls on taking waste out of the
locality. However, certain state and local jurisdictions continue to seek to
enforce such restrictions and, in certain cases, Casella may elect not to
challenge such restrictions. In addition, the aforementioned proposed Federal
legislation would allow states and localities to impose certain flow control
restrictions. These restrictions could reduce the volume of waste going to
landfills in certain areas, which may materially adversely affect Casella's
ability to operate its landfills and/or affect the prices that can be charged
for landfill disposal services. These restrictions may also result in higher
disposal costs for Casella's collection operations. If Casella were unable to
pass such higher costs through to its customers, Casella's business, financial
condition and results of operations could be materially adversely affected.

    There has been an increasing trend at the Federal, state and local levels to
mandate or encourage both waste reduction at the source and waste recycling, and
to prohibit or restrict the disposal in landfills of certain types of solid
wastes, such as yard wastes, leaves and tires. The enactment of regulations
reducing the volume and types of wastes available for transport to and disposal
in landfills could affect Casella's ability to operate its landfill facilities.

PROPERTIES

    The principal fixed assets used by Casella in connection with its landfill
operations are its landfills which are described above.

    Other than the landfills, the principal fixed assets used by Casella in its
solid waste collection and landfill operations included, at July 15, 1999,
approximately 1,402 collection vehicles, 195 pieces of heavy equipment and 261
support vehicles. At September 1, 1999, transfer station operations included 54
transfer stations, 27 of which are owned and 27 of which are leased and/or
operated under agreements expiring between 1999 and 2021.

    At September 1, 1999, Casella utilized 16 recycling facilities in its
service areas, of which seven are owned and nine are leased and/or operated
under agreements expiring between 1999 and 2021.

    Casella owns and operates a 46-acre tire processing facility located in
Eliot, Maine, consisting of storage facilities, tire shredding machines and a
scale and receiving area.

    Casella's facility in Rutland, Vermont, consisting of approximately 10,000
square feet utilized for Casella's headquarters, and its solid waste collection,
maintenance and septic hauling facility located in Montpelier, Vermont,
consisting of an aggregate of approximately 24,000 square feet, are leased from
Casella Associates, a company owned by John and Douglas Casella.

LEGAL PROCEEDINGS

    On or about October 30, 1997, Mr. Matthew M. Freeman commenced a civil
lawsuit against Casella and two of Casella's officers and directors in the
Rutland Superior Court, Rutland County, State of Vermont. In the complaint, Mr.
Freeman seeks compensation for services allegedly performed by him prior to
1995. Mr. Freeman is seeking a three-percent equity interest in Casella or the
monetary equivalent thereof, as well as punitive damages. Casella and the
officers and directors have answered the complaint, denied Mr. Freeman's
allegations of wrongdoing, and asserted various defenses. In order to facilitate
the completion of the initial public offering of Casella's Class A Common Stock
in November, 1997, certain stockholders of Casella agreed to indemnify Casella
for any settlement by Casella or any award against Casella in excess of $350,000
(but not legal fees paid by or on behalf of Casella or any other third party).
Casella accrued a $215,000 reserve for this claim during the year ended
April 30, 1998.

    On May 12, 1998, Casella filed suit in New York Supreme Court, Allegany
County against the Town of Angelica, New York seeking a temporary restraining
order and preliminary injunctive relief against the Town's enforcement of a
recently-enacted local law which would prohibit the expansion of the Hyland
landfill, would require the landfill and the operator thereof to receive an
additional permit from the Town of Angelica to continue to operate, would
prevent the disposal of yard waste, may preclude the disposal of certain types
of industrial waste and would impose certain other restrictions on the landfill.
A temporary restraining order was granted by the court on May 14, 1998 in favor
of Casella, and by a decision dated July 13, 1998, the court granted Casella's
motion for a preliminary injunction. On September 9, 1998, the Town of Angelica
filed a Notice of Appeal but has not yet perfected that appeal. If Casella is
not successful in its lawsuit, and if the Town of Angelica seeks to enforce the
law by its terms, then Casella would be required to obtain an additional permit
from the Town of Angelica to operate the Hyland landfill, the expansion of the
landfill beyond the current permitted capacity would be prohibited, and Casella
would be unable to dispose of yard waste and may be precluded from disposing of
certain industrial wastes at the landfill. There can be no assurance that such
limitations would not have a material adverse effect on Casella's business,
financial condition and results of operations. Casella began accepting waste at
the Hyland facility on July 22, 1998, and is in active settlement negotiations
with the town.

    Casella's wholly-owned subsidiary, North Country Environmental Services,
Inc. ("NCES"), is a party to consolidated civil actions (Case Nos. 98-E-141 and
98-E-151) against the Town of Bethlehem,

                                       70
<PAGE>
New Hampshire, before the Grafton Superior Court in North Haverhill, New
Hampshire. On October 16, 1998, NCES commenced an action for declaratory relief
against the Town of Bethlehem seeking, on a variety of grounds, to invalidate a
zoning ordinance which purports to prohibit the expansion of NCES's landfill
beyond its currently permitted capacity. The Town of Bethlehem has taken the
position that NCES may not expand the landfill beyond Stage II, Phase I, which
has reached capacity. NCES sought a declaration that it requires no further
approvals from the Town of Bethlehem to expand the landfill throughout its
87-acre parcel and that certain financial exactions imposed by a 1986 Town of
Bethlehem land-use approval are invalid. In the alternative, NCES sought
compensation under state law for the inverse condemnation of its property.

    On October 23, 1998, the Town filed a petition for injunctive and
declaratory relief against NCES. The Town's petition sought to enjoin NCES's
construction of Stage II, Phase II of the landfill and to prevent any further
expansion as violative of the above-noted Town zoning ordinance. The
construction of Stage II, Phase II was proceeding at that time pursuant to a
construction permit issued by the New Hampshire Department of Environmental
Services (NHDES) on September 15, 1998. On October 30, 1998, the court entered a
preliminary injunction requiring NCES to suspend construction of Stage II, Phase
II. When the Town failed to post an injunction bond, however, the court
permitted NCES to complete and cover the liner system in Stage II, Phase II,
before the onset of winter.

    On November 30, 1998, NCES and the Town proceeded to trial on eight of
NCES's eleven claims for relief and on the Town's claims for permanent
injunctive and declaratory relief. Earlier, the remaining three NCES claims were
bifurcated for later trial, if needed. On the day of trial, the Town filed two
counterclaims seeking to establish the lawfulness of the financial exactions
challenged by NCES's October 16, 1998 petition.

    The Grafton Superior Court issued its order on NCES's first eight claims and
the Town's request for a permanent injunction and declaratory relief on
February 1, 1999. The court declined to decide whether the Town's zoning
ordinance is valid; rather, the court held that NCES had appropriated a 51-acre
tract of land comprised of a 10-acre and a 41-acre parcel for landfilling
purposes. Stage II, Phase II is within the 51-acre tract. The court also found
that NCES had obtained permission to operate its landfill facility on this
51-acre tract prior to the enactment of the challenged zoning ordinance and held
that the ordinance did not apply to NCES's operation of its landfill facility on
this tract. Consequently, the court held that the Town lacked authority to
enforce the zoning ordinance against NCES with respect to the 51-acre tract and
denied the Town's petition in its entirety. The court did not decide the
validity of the zoning ordinance as it relates to 36 acres adjoining the 51-acre
tract after finding that NCES had not demonstrated a present intent to develop
this property for landfilling. Consequently, NCES's ability to use this 36 acres
for landfilling remains unresolved.

    On February 10, 1999, the Town moved the Grafton Superior Court to clarify
and reconsider its order. On March 22, 1999, the court denied reconsideration
but offered some clarification which did not result in any substantive change in
its earlier order. On April 20, 1999, the Town filed a notice of appeal with the
New Hampshire Supreme Court seeking review of the superior court's order. NCES
filed a notice of cross-appeal on April 29, 1999.

    Concurrently, on March 24, 1999, a special interest group, Environmental
Action for Northern New Hampshire, Inc. ("EANNH") sought to intervene before the
superior court. The reason EANNH gave for seeking intervention was to introduce
evidence which it claimed showed that there were size limitations on the
landfill implicit in the land-use approvals obtained by NCES's predecessors in
1976 and 1986. The superior court denied EANNH intervention on April 22, 1999,
and on May 24, 1999, EANNH appealed the denial of intervention to the New
Hampshire Supreme Court.

    The Town's notice of appeal centers on its argument that there were implied
limitations upon the size of the landfill that could be operated by NCES and its
predecessors under the land-use approvals granted by the Town in 1976 and 1986.
NCES's cross-appeal seeks a determination that it has all local approvals
necessary to landfill throughout the entire 87-acre parcel, that the Town's
restrictive zoning

                                       71
<PAGE>
ordinance is unlawful for several reasons, and that the Town's attempted
enforcement of the zoning ordinance was in bad faith, entitling NCES to its
attorney's fees.

    The New Hampshire Supreme Court has yet to accept any of the appeals. NCES
has filed a motion for summary disposition of EANNH's appeal, but there has yet
to be a ruling on that motion. NCES has also learned that a second special
interest group, AWARE, Inc., intends to seek AMICUS CURIAE status so it may
submit briefs to the Supreme Court in support of the Town's appeal.

    In summer 1999, the superior court found that the financial exactions
imposed in 1986 by the Town as a condition of land-use approval were unlawful.
These exactions consisted of a discounted tipping fee for Town solid waste and a
per-ton payment to the Town for all solid waste originating from outside the
Town and deposited at the landfill. NCES stopped complying with the exactions in
October of 1998. NCES expects an appeal.

    In a separate but related matter, the Waste Management Division of NHDES
issued operating approval to NCES for Stage II, Phase II of the landfill on
March 25, 1999. NCES has been landfilling in Stage II, Phase II since that time.
On April 23, 1999, EANNH appealed the operating approval to the Waste Management
Council, an appellate administrative body with jurisdiction to review certain
decisions of the Waste Management Division. EANNH has contended on its appeal
that the operating approval should be suspended because the superior court's
order in NCES's favor is on appeal and hence not final. EANNH has also argued
that NCES misled the Waste Management Division into issuing the operating
approval by certifying that it had all local approvals necessary to operate
Stage II, Phase II when the order establishing this proposition was on appeal.

    NCES has filed a motion to dismiss EANNH's appeal to the Waste Management
Council on the ground that the Council lacks jurisdiction over the appeal and
that EANNH lacks standing to assert it. The Office of the Attorney General of
the State of New Hampshire has joined in that motion. In the alternative, NCES
has sought a stay of the Council proceedings pending the outcome of the Supreme
Court appeal. EANNH has agreed to a stay provided there is a suspension of the
operating approval during the pendency of the Supreme Court appeal. NCES has
objected to any such suspension.

    Following the announcement of the merger, Casella received a request for
certain information and documents from the Maine Attorney General related to its
existing operations in the State of Maine, and to the competitive impact of the
proposed merger with KTI. In response to this request, Casella made available
certain responsive information and documents. Since that time, without an
admission of any liability, Casella has entered into an agreement resolving the
Attorney General's competitive concerns. The agreement, formally contained in a
Consent Order, was submitted to the Maine Superior Court and approved on
September 28, 1999, to become effective upon the date of the consummation of the
merger. In summary, the Order requires Casella to modify its existing small
containerized hauling contracts in northern Maine to permit termination upon
thirty days written notice and to limit the charge for early termination to a
certain amount. It also requires Casella to operate (to the extent it controls
such operation) the gate, scale house and disposal area of the Penobscot
waste-to-energy facility in Orrington, Maine, under terms and conditions no less
favorable than those provided to it and to be recused from participation in the
bid process for contracts relating to the transportation or disposal or residue
from that facility.

    Casella has brought an action against the Town of Hampden, Maine to set
aside the Town's efforts to block Casella's construction of approximately
3,300,000 tons of capacity, for which Casella has been granted a permit by the
State of Maine. The action is pending in the Penobscot County Superior Court in
Bangor, Maine.

    Casella offers no prediction of the outcome of any of the proceedings
described above.

                                       72
<PAGE>
    In addition to the foregoing, Casella may periodically become subject to
various judicial and administrative proceedings involving Federal, state or
local agencies in the normal course of its business and as a result of the
extensive governmental regulation of the waste industry. In these proceedings,
an agency may seek to impose fines on Casella or to revoke, or to deny renewal
of, an operating permit held by Casella. In addition, Casella may become party
to various claims and suits pending for alleged damages to persons and property,
alleged violation of certain laws and for alleged liabilities arising out of
matters occurring during the normal operation of the waste management business.
However, there is no current proceeding or litigation involving Casella that it
believes will have a material adverse effect upon Casella's business, financial
condition and results of operations.

STOCK OWNERSHIP OF MANAGEMENT

    The following table sets forth information as of September 1, 1999 and
immediately following the merger, regarding the beneficial ownership of Casella
common stock by (a) each person or entity known to Casella to beneficially own
more than five percent of Casella common stock; (b) each director; (c) the chief
executive officer and the two other most highly compensated executive officers
of Casella as of September 1, 1999; and (d) all current directors and executive
officers of Casella as a group.

    Beneficial ownership is determined in accordance with the rules of the SEC,
and includes generally voting power and/or investment power with respect to
securities. Shares of common stock subject to options and/or warrants currently
exercisable or exercisable within 60 days of September 1, 1999 are deemed
outstanding for computing the percentage beneficially owned by the person
holding the options and/or warrants but are not deemed outstanding for purposes
of computing the percentage beneficially owned by any other person. Except as
indicated by footnote, Casella believes that the persons named in this table,
based on information provided by these persons, have sole voting and investment
power with respect to the shares of common stock indicated.

    REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

    The compensation committee of the Casella board reviews executive salaries,
administers any bonus, incentive compensation and stock option plans of Casella,
and approves the salaries and other benefits of the executive officers of
Casella. In addition, the compensation committee consults with Casella's
management regarding pension and other benefit plans and compensation policies
and practices of Casella.

    The compensation committee, including its stock plan subcommittee, seeks to
achieve three broad goals in connection with Casella's executive compensation
program. First, the compensation committee seeks to reward executives for the
achievement of business objectives of Casella. Second, the executive
compensation program is intended to provide executives with equity incentives so
as to link a portion of the executive's compensation with the future performance
of Casella Class A common stock. Finally, the compensation committee structures
its executive compensation program so as to enable it to attract and retain key
executives.

    To achieve these objectives, the compensation program for Casella's
executive officers consists principally of three elements: base salary, cash
bonuses and long-term incentive compensation in the form of participation in
Casella's stock option plans.

    In determining base salaries for the executive officers, the compensation
committee evaluates the executive's experience, historical salary level and the
responsibilities of the specific executive position. In addition, the
compensation committee assesses Casella's financial and operational performance
for the prior fiscal year and the competitiveness of Casella's executive
compensation program and executive compensation packages of comparable
companies. To the extent determined to be appropriate, the compensation
committee also considers general economic conditions and forecasts. Base
salaries are generally set at or somewhat below competitive levels, with the
result that Casella relies on cash

                                       76
<PAGE>
bonuses and longer term incentive compensation to motivate its executive
officers to perform to the full extent of their abilities.

    The compensation committee also considers the payment of cash bonuses as
part of its compensation program. Annual cash bonuses reflect a policy of
requiring a certain level of company financial and operational performance for
the prior fiscal year before any cash bonuses are earned by executive officers.
In general, the compensation committee has tied potential bonus compensation to
performance factors, including the executive officer's efforts and contributions
towards obtaining company objectives and Casella's overall growth.

    The executive officers are also eligible to receive stock options under
Casella's stock option plans. The compensation committee believes that it is to
Casella's advantage to increase the interest of the executives in Casella's
welfare, as these employees share the primary responsibility for Casella's
management and growth. In addition, the compensation committee believes that,
because new option grants are generally set at fair market value, the grants
have the effect of "re-setting" the executive's price targets for Casella
Class A common stock. Moreover, Casella's stock option plans provide a
significant non-cash form of compensation, which is intended to benefit Casella
by enabling it to continue to attract and to retain qualified personnel without
negatively impacting cash flow. The stock plan subcommittee administers the
issuance of stock options and other awards under Casella's stock option plans to
the executive officers. See "Report of the stock plan subcommittee on executive
compensation".

    COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(M)

    Section 162(m) of the Internal Revenue Code of 1986, as amended, enacted in
1993, generally disallows a tax deduction to public companies for compensation
over $1,000,000 paid to its chief executive officer and its four other most
highly compensated executive officers. Qualifying performance-based compensation
will not be subject to the deduction limit if certain requirements are met. In
this regard, Casella has limited the number of shares subject to stock options
which may be granted to Casella's employees in a manner that complies with the
performance-based requirements of Section 162(m). Based on the compensation
awarded to the chief executive officer and the other named executive officers of
Casella, it does not appear that the Section 162(m) limitation will have a
significant impact on Casella in the near term. Incentive stock-based awards
granted prior to fiscal 1999 by Casella generally qualify as a performance-based
compensation pursuant to the "grandfather" provision of Section 162(m).

    REPORT OF THE STOCK PLAN SUBCOMMITTEE ON EXECUTIVE COMPENSATION

    The stock plan subcommittee of the compensation committee administers the
issuance of stock options and other awards under Casella's stock option plans to
Casella's executive officers and approves the compensation of Mr. John W.
Casella.

    The use of stock options is a significant element of the compensation
packages of Casella's executive officers. The timing of new grants depends upon
a number of factors, including the executives' current stock and option holdings
and such other factors as the stock plan subcommittee deems relevant. In fiscal
1999, the stock plan subcommittee granted stock options to each of the named
executive officers. In its determination to grant stock options to the Casella
named executive officers,

                                       77
<PAGE>
the stock plan subcommittee specifically considered the successful consummation
of Casella's secondary public offering of its Class A common stock, the entering
into of the agreement and plan of merger with KTI, the achievement of certain
milestones with respect to the company's landfills and Casella's successful
business acquisitions.

    When recommending the grant of stock options, it has been the policy of the
stock plan subcommittee to recommend that the exercise price of the options be
equal to the fair market value of a share of Casella Class A common stock as of
the date of grant.

    The compensation of the chief executive officer is based upon the same
elements and measures of performance as is the compensation for Casella's other
executive officers. In its determination to approve a cash bonus in fiscal 1999
to Mr. John W. Casella of $60,000, the stock plan subcommittee specifically
considered the successful consummation of Casella's secondary public offering of
its Class A common stock, the entering into of the agreement and plan of merger
with KTI, Casella's successful business acquisitions and Casella's overall
growth during fiscal 1999.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

    Casella has from time to time engaged Casella Construction, Inc., a company
owned by John W. Casella and Douglas R. Casella, a director, to provide
construction services for the company, including construction, closure and
capping activities at the company's landfills. In fiscal 1999, the company paid
Casella Construction, Inc. an aggregate of $5,198,000.

    Casella is party to two real estate leases with Casella Associates, a
Vermont partnership owned by John W. Casella and Douglas R. Casella, relating to
facilities occupied by the company. The leases, relating to the company's
corporate headquarters in Rutland, Vermont and its Montpelier, Vermont facility,
call for aggregate monthly payments of approximately $18,000 and expire in
April 2003. These leases have been classified by the company as capital leases
for financial reporting purposes. In addition, the company leases furniture and
fixtures from Casella Associates pursuant to an operating lease which bore rent
at $950 per month and which expired in May 1999. In fiscal 1999, the company
paid Casella Associates an aggregate of $237,101 for such leases. In
November 1997, the lease relating to the company's corporate headquarters in
Rutland, Vermont was amended to allow the company to upgrade and make capital
improvements to the premises at an estimated cost of $500,000, to be paid by the
company. Casella Associates was granted the option to purchase the capital
improvements by December 31, 2002, and if it does not elect to exercise the
option the company has the right to purchase the premises for $324,000, the fair
market value of the premises prior to the capital improvements, at the
expiration of the term of the lease.

    Casella operated an unlined landfill located in Whitehall, New York owned by
Bola, Inc., a corporation owned by John W. Casella and Douglas R. Casella which
operated as a single-purpose real estate holding company. The company paid the
cost of closing this landfill in 1992, and has agreed to pay all post-closure
obligations. In fiscal 1999, the company paid an aggregate of $3,161 pursuant to
this arrangement.

    In connection with and at the time of Casella's acquisition of the business
of Catamount Waste Services, Inc., Casella entered into a lease in June 1994
with CV Landfill, Inc., a Vermont corporation affiliated with Catamount Waste
Services, Inc., pursuant to which Casella agreed to lease a transfer station for
a term of 10 years. CV Landfill, Inc. is owned by John F. Chapple III, who
became a

                                       78
<PAGE>
director of Casella at the time of the acquisition of the business of Catamount
Waste Services, Inc. Pursuant to the lease agreement, Casella pays monthly rent
for the first five years at a rate of $5.00 per ton of waste disposed of at the
transfer station, with a minimum rent of $6,650 per month. Following the fifth
anniversary of the lease agreement, Casella is required to pay monthly rent at a
rate of $2.00 per ton, with a minimum rent of $2,500 per month. In fiscal 1999,
Casella paid CV Landfill, Inc. an aggregate of $116,116.

    In connection with the settlement of certain litigation naming the company,
four of its subsidiaries, Messrs. James W. Bohlig and John W. and Douglas R.
Casella and one unrelated person as defendants, the company paid an aggregate of
$450,000 plus approximately $200,000 in legal expenses incurred by the
defendants. The lawsuit was brought derivatively in the name of Meridian, a
Vermont corporation which has been inactive since 1993, of which Messrs. Bohlig
and John Casella were officers, directors and stockholders, as well as
individually in the names of the plaintiffs, who were also stockholders of
Meridian. In response to the lawsuit, in an effort to expedite adjudication, a
majority of Meridian's directors, including Messrs. Bohlig and John Casella,
voted to place Meridian into bankruptcy, and Meridian filed a petition under
Chapter 7. The lawsuit was subsequently removed to the United States Bankruptcy
Court for the District of Vermont. On July 14, 1997, the bankruptcy court
approved the settlement. Messrs. Bohlig and John Casella were officers and
directors of Meridian at the time Meridian filed the petition under Chapter 7.

    On or about October 30, 1997, Mr. Matthew M. Freeman commenced a civil
lawsuit against the company and Messrs. James W. Bohlig and John W. Casella in
the Rutland Superior Court, Rutland County, State of Vermont. In the complaint,
Mr. Freeman seeks compensation for services allegedly performed by him prior to
1995. Mr. Freeman is seeking a three percent equity interest in the company or
the monetary equivalent thereof, as well as punitive damages. The company and
Messrs. Bohlig and Casella have answered the complaint, denied Mr. Freeman's
allegations of wrongdoing, and asserted various defenses. In order to facilitate
the completion of the Casella initial public offering, certain stockholders of
the company, including the two officers named as defendants, agreed to indemnify
the company for any settlement by the company or any award against the company
in excess of $350,000, but not including legal fees paid by or on behalf of the
company or any other party. The company has agreed to indemnify Messrs. Bohlig
and Casella for legal fees incurred by them in connection with the lawsuit, plus
settlements or awards up to $350,000 in the aggregate.

    Casella believes that each transaction described above was on terms at least
as favorable as those Casella would expect to negotiate with disinterested third
parties. In addition, in connection with the proposed merger with KTI, certain
executive officers and directors of Casella and KTI have interests in the merger
that are in addition to their interests as stockholders of the companies
generally. See "The Merger--Interests of executive officers and directors of
Casella and KTI in the merger" and "The Companies--KTI--Certain relationships
and related transactions".

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

    Based solely on its review of copies of reports filed by reporting persons
pursuant to Section 16(a) of the Securities Exchange Act of 1934, or written
representations from reporting persons that no Form 5 filing was required for
such person, Casella believes that, during fiscal 1999, all filings required to
be made by reporting persons of Casella were timely made in accordance with the
requirements of the Exchange Act other than the filing of a Form 4 by
Mr. Robert G. Banfield, a vice president, which reported two late transactions;
the filing of a Form 4 by Mr. Michael P. Barrett, a vice president, which
reported five late transactions; the filing of a Form 4 by Mr. James W. Bohlig,
senior vice president, chief operating officer and a director, which reported
three late transactions; the filing of a Form 5 by Mr. Douglas R. Casella, a
director, which reported two late transactions; the filing of a Form 4 and a
Form 5 by Mr. John W. Casella, president, chief executive officer and chairman,

           CASELLA MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

    The following discussion of Casella's financial condition and results of
operations should be read in conjunction with Casella's Consolidated Financial
Statements and Notes thereto, and other financial information included elsewhere
herein.

OVERVIEW

    Casella is a regional, integrated solid waste services company that provides
collection, transfer, disposal and recycling services in Vermont, New Hampshire,
Maine, upstate New York, Massachusetts and northern Pennsylvania. Casella's
objective is to continue to grow by expanding its services in markets where it
can be one of the largest and most profitable fully-integrated solid waste
services companies.

    Casella's revenues have increased from $38.6 million for the fiscal year
ended April 30, 1995, to $184.2 million for the fiscal year ended April 30,
1999. From May 1, 1994 through April 30, 1999, Casella acquired 132 solid waste
collection, transfer and disposal operations. Between May 1 and July 31, 1999,
Casella acquired an additional 13 such businesses. All but two of these
acquisitions were accounted for under the purchase method of accounting for
business combinations. Under the rules of purchase accounting the acquired
companies' revenues and results of operations have been included together with
those of Casella from the actual dates of the acquisitions and will materially
affect the period-to-period comparisons of Casella's historical results of
operations. In December 1997 Casella acquired a waste collection and transfer
operation in a transaction recorded as a pooling of interests. During the fiscal
year ended April 30, 1999 Casella acquired five waste collection, transfer and
disposal operations in transactions accounted for as poolings of interest. From
May 1, 1999 through July 31, 1999 Casella acquired two additional waste
collection and transfer operations in transactions accounted for as poolings of
interests. Under the rules governing poolings of interest, the prior period and
year to date financial statements of Casella have been restated for all prior
years to reflect the financial position, results of operations and cash flows of
the merged entities as if they had been one company for all periods presented in
the accompanying financial statements.

GENERAL

    Casella's revenues are attributable primarily to fees charged to customers
for solid waste collection, disposal, transfer and recycling services. Casella
derives a substantial portion of its collection revenues from commercial,
industrial and municipal services that are generally performed under service
agreements or pursuant to contracts with municipalities. The majority of
Casella's residential collection services are performed on a subscription basis
with individual households. Landfill and transfer customers are charged a
tipping fee on a per ton basis for disposing of their solid waste at Casella's
disposal facilities and transfer stations. The majority of Casella's landfill
and transfer customers are under one-year to ten-year disposal contracts, with
most having clauses for annual cost of living increases. Recycling revenues
consist of revenues from the sale of recyclable commodities and from the sale of
tire derived fuel. Other revenues consist primarily of revenue from waste tire
tipping fees, and septic/liquid waste operations. Casella's revenues are shown
net of intercompany eliminations. Casella typically establishes its intercompany
transfer pricing based upon prevailing market rates.

    The table below shows, for the periods indicated, the percentage of
Casella's revenues attributable to services provided. The increase in Casella's
collection revenues as a percentage of revenues for the fiscal years ended
April 30, 1998 and 1999 is primarily attributable to the impact of Casella's
acquisition of collection businesses during these periods, as well as to
internal growth through price and business volume increases. The decrease in
Casella's landfill revenues and in Casella's transfer revenues as a percentage
of revenues for the fiscal years ended April 30, 1998 and fiscal 1999 is mainly
due to a

                                       83
<PAGE>
proportionately greater increase in collection and other revenues occurring as
the result of acquisitions in those areas; also, as Casella acquires collection
businesses from which it previously had derived transfer or disposal revenues,
the acquired revenues are recorded by Casella as collection revenues. The
decrease in Casella's collection revenues as a percentage of revenues and the
increase of Casella's landfill revenues as a percentage of revenues for the
three months ended July 31, 1999 is primarily attributable to the impact of
Casella's acquisition of Hyland Landfill during the first quarter of fiscal 1999
plus the increased utilization of its North Country Landfill in Bethlehem, New
Hampshire during the first quarter of fiscal 2000. The increase in transfer
revenues as a percentage of revenues for the three months ended July 31, 1999 is
mainly due to the acquisition of transfer station operations in the prior fiscal
year. The increase in recycling revenues for the three months ended July 31,
1999 is due primarily to increased volumes with additional increased prices
received from the sale of recycled commodities. The increase in liquid waste and
other revenues as a percentage of revenues for the three months ended July 31,
1999 is primarily due to the impact of acquisitions of septic/liquid waste
operations since the first quarter of fiscal 1999.

    Cost of operations includes labor, tipping fees paid to third party disposal
facilities, fuel, maintenance and repair of vehicles and equipment, worker's
compensation and vehicle insurance, the cost of purchasing materials to be
recycled, third party transportation expense, district and state taxes, host
community fees and royalties. Landfill operating expenses also include a
provision for closure and post-closure expenditures anticipated to be incurred
in the future, and leachate treatment and disposal costs.

    General and administrative expenses include management, clerical and
administrative compensation and overhead, professional services and costs
associated with Casella's marketing and sales force and community relations
expense.

    Depreciation and amortization expense includes depreciation of fixed assets
over the estimated useful lives of the assets using the straight line method,
amortization of landfill airspace assets under the units-of-production method,
and the amortization of goodwill and other intangible assets using the straight
line method. The amount of landfill amortization expense related to airspace
consumption can vary materially from landfill to landfill depending upon the
purchase price and landfill site and cell development costs. Casella depreciates
all fixed and intangible assets, excluding non-depreciable land, down to a $0
net book value, and does not apply a salvage value to any of its fixed assets.

    Certain direct landfill development costs, such as engineering, permitting,
legal, construction and other costs directly associated with expansion of
existing landfills, are capitalized by Casella. Additionally, Casella also
capitalizes certain third party expenditures related to pending acquisitions,

                                       84
<PAGE>
such as legal and engineering. Casella will have material financial obligations
relating to closure and post-closure costs of its existing landfills and any
disposal facilities which it may own or operate in the future. Casella has
provided and will in the future provide accruals for future financial
obligations relating to closure and post-closure costs of its landfills
(generally for a term of 30 years after final closure of a landfill) based on
engineering estimates of consumption of permitted landfill airspace over the
useful life of any such landfill. There can be no assurance that Casella's
financial obligations for closure or post-closure costs will not exceed the
amount accrued and reserved or amounts otherwise receivable pursuant to trust
funds. Casella routinely evaluates all such capitalized costs, and expenses
those costs related to projects not likely to be successful. Internal and
indirect landfill development and acquisition costs, such as executive and
corporate overhead, public relations and other corporate services, are expensed
as incurred.

*   See discussion and computation of adjusted EBITDA below.

THREE MONTHS ENDED JULY 31, 1999 VERSUS JULY 31, 1998

    REVENUES.  Revenues increased $9.9 million, or 22.2%, to $55.0 million in
the quarter ended July 31, 1999 from $45.1 in the quarter ended July 31, 1998.
Of this increase, $5.7 million of the growth was due to the impact of businesses
acquired during fiscal year 1999 and during the first quarter of the current
fiscal year. The balance of the increase was due to internal volume and price
growth.

    COST OF OPERATIONS.  Cost of operations increased approximately
$3.6 million, or 13.2%, to $30.9 million in the quarter ended July 31, 1999 from
$27.3 million in the same quarter of the prior

                                       85
<PAGE>
fiscal year. Cost of operations as a percentage of revenues decreased to 56.2%
in the quarter ended July 31, 1999 from 60.6% in the same quarter of the prior
fiscal year. The decrease was primarily the result of: (i) productivity
improvements in Casella's collection operations as a result of better route
density from acquisitions, routing efficiencies through route audits and
front-end loader vehicle conversions completed throughout fiscal 1999; and
(ii) margin improvements because of price increases in fiscal 1999 and the first
quarter of fiscal year 2000.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
approximately $1.4 million, or 21.9%, to $7.8 million in the quarter ended
January 31, 1999 from $6.4 million in the same quarter of the prior fiscal year.
General and Administrative expenses as a percentage of revenues have remained
approximately level in the periods under discussion.

    MERGER COSTS.  The merger related costs of $1.5 million recorded in the
quarter ended July 31, 1999 were incurred in association with the Resource Waste
Systems, Inc. and Corning Community Disposal, Inc. mergers accounted for as
poolings of interests.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense
increased $1.7 million, or 28.8%, to $7.6 million in the quarter ended July 31,
1999 from $5.9 million in the same quarter of the prior fiscal year.
Depreciation and amortization as a percentage of revenues increased to 13.9% in
the quarter ended July 31, 1999 from 13.1% in the same quarter of the prior
fiscal year. The increase in depreciation and amortization is due to the
increased concentration of revenues in landfill activities, which typically have
higher depreciation and amortization charges relative to revenues compared to
hauling revenues.

    INTEREST EXPENSE, NET.  Net interest expense decreased approximately $0.3
million, or 15.8% to $1.6 million in the quarter ended July 31, 1999 from $1.9
million in the same quarter of the prior fiscal year. This decrease primarily
reflects the reduction of the outstanding balance under Casella's acquisition
line of credit and other notes payable from the proceeds of Casella's public
stock offering in July, 1998.

    OTHER (INCOME) EXPENSE, NET.  Net other (income) expense has not
historically been material to Casella's results of operations.

    PROVISION FOR INCOME TAXES.  Provision for income taxes increased
approximately $0.9 million to $2.6 million in the quarter ended July 31, 1999
from $1.7 million in the same quarter of the prior fiscal year. This increase
reflects Casella's increase in profits in the quarter ended July 31, 1999 over
the same quarter in the prior fiscal year. The combined effective tax rate used
by Casella in recording taxes for interim periods has been increased from 44.1%
in the quarter ended July 31, 1998 to 46.0% in the same quarter of the current
fiscal year. This increase reflects the non-deductible merger expenses incurred
during the quarter ended July 31, 1999.

FISCAL YEAR ENDED APRIL 30, 1999 VERSUS APRIL 30, 1998

    REVENUES.  Revenues increased $40.5 million, or 28.2%, to $184.2 million in
fiscal 1999 from $143.7 million in fiscal 1998. Approximately $28.6 million of
the increase was attributable to the impact of businesses acquired throughout
fiscal 1998 and fiscal 1999. In addition, approximately $11.9 million of the
increase was attributable to internal volume and price growth (net of the
negative impact of lower average recycled commodity processing in fiscal 1999
compared to fiscal 1998).

    COST OF OPERATIONS.  Cost of operations increased approximately $20.4
million, or 22.8%, to $110.0 million in fiscal 1999 from $89.6 million in fiscal
1998, an increase corresponding primarily to Casella's revenue growth described
above. Cost of operations as a percentage of revenues decreased to 59.7% in
fiscal 1999 from 62.3% in fiscal 1998. The decrease was primarily the result of:
(i) productivity improvements in Casella's collection operations as a result of
better route density from acquisitions,

                                       86
<PAGE>
routing efficiencies through route audits and front-end loader vehicle
conversions completed throughout fiscal 1998 and 1999; (ii) margin improvements
because of price increases in fiscal 1998 and 1999 and (iii) higher landfill
internalization due to the Hyland landfill becoming operational in July, 1998.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
approximately $6.1 million, or 29.2%, to $27.0 million in fiscal 1999 from $20.9
million in fiscal 1998. General and administrative expenses as a percentage of
revenues increased to 14.7% in fiscal 1999 from 14.6% in fiscal 1998 due
primarily to an increase in management information systems spending and public
company expenditures for a full year in fiscal 1999 compared to a partial year
in fiscal 1998.

    MERGER-RELATED COSTS.  Merger-related costs consists of legal, engineering,
accounting and other costs associated with the various poolings of interests
consummated during fiscal 1998 and 1999. One such transaction occurred during
fiscal 1998 and five occurred fiscal 1999, resulting in an increase of $1.7
million or 567%. Merger-related costs as a percentage of revenue increased from
0.2% in fiscal 1998 to 1.1% in fiscal 1999.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense
increased $5.9 million, or 29.5%, to $25.9 million in fiscal 1999 from $20.0
million in fiscal 1998. As a percentage of revenues, depreciation and
amortization expense increased to 14.1% in fiscal 1999 from 13.9% in fiscal
1998. The increase in depreciation and amortization expense as a percentage of
revenues was primarily the result of: (i) higher rates of disposal
internalization due to the opening of the Hyland landfill, (ii) higher landfill
volumes in fiscal 1999 compared to fiscal 1998, resulting in higher landfill
amortization expense, and (iii) front end loader conversions resulting in double
container depreciation charges at certain locations.

    LOSS ON IMPAIRMENT OF LONG-LIVED ASSETS.  Casella recognized losses on
impairment of long-lived assets in the fourth quarter of fiscal 1998 in the
amount of $1.6 million. The impairment charges were non-cash charges to write
down the assets of Casella's waste tire processing facility in Eliot, Maine and
the Grasslands composting facility in Malone, New York to their fair market
values as of April 30, 1998.

    INTEREST EXPENSE, NET.  Net interest expense decreased approximately $1.8
million, or 24.3% to $5.6 million in fiscal 1999 from $7.4 million in fiscal
1998. This decrease primarily reflects decreased average indebtedness in fiscal
1999, resulting from debt payoffs following the public stock offerings in
October 1997 and July 1998, from the increased use of Casella's Class A common
stock in effecting acquisitions, and from improved collections efforts. Days
sales in accounts receivable was 45.3 at April 30, 1999 compared to 50.3 at
April 30, 1998. Casella capitalized a total of $0.5 million in interest expense
in fiscal 1999, compared to a total of $0.1 million in fiscal 1998.

    OTHER (INCOME) EXPENSE, NET.  Net other (income) expense was not material to
Casella's results of operations in fiscal 1998 and 1999.

    PROVISION FOR INCOME TAXES.  Provision for income taxes increased
approximately $5.0 million, or 199.2%, to $7.5 million in fiscal 1999 from $2.5
million in fiscal 1998. This increase reflects Casella's increase in
profitability in fiscal 1999 compared to fiscal 1998. Among the factors causing
income tax expense as a percentage of pre-tax net income to vary materially from
year to year are: (i) the recording of a fixed asset impairment charge in fiscal
1998 which was non-deductible for income tax purposes, and (ii) poolings of
interest resulting in prior period restatements of entities not liable for
federal income tax due to subchapter S status.

FISCAL YEAR ENDED APRIL 30, 1998 VERSUS APRIL 30, 1997

    REVENUES.  Revenues increased $40.2 million, or 38.8%, to $143.7 million in
fiscal 1998 from $103.5 million in fiscal 1997. Approximately $36.0 million of
the increase was attributable to the impact of businesses acquired throughout
fiscal 1997 and fiscal 1998. In addition, approximately $3.8 million of the
increase was attributable to internal volume and price growth. The balance of
the increase of approximately $400,000 was due to higher average recyclable
commodity prices in fiscal 1998 compared to fiscal 1997.

    COST OF OPERATIONS.  Cost of operations increased $24.1 million, or 36.8%,
to $89.6 million in fiscal 1998 from $65.5 million in fiscal 1997, an increase
corresponding primarily to Casella's revenue growth described above. Cost of
operations as a percentage of revenues decreased to 62.3% in fiscal 1998 from
63.3% in fiscal 1997. The decrease was primarily the result of:
(i) productivity improvements in Casella's collection operations as a result of
better route density from acquisitions, routing efficiencies through route
audits and front-end loader vehicle conversions completed throughout fiscal
1998, and (ii) margin improvements because of price increases in fiscal 1998.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
approximately $4.8 million, or 29.8%, to $20.9 million in fiscal 1998 from $16.1
million in fiscal 1997. General and administrative expenses as a percentage of
revenues decreased to 14.6% in fiscal 1998 from 15.6% in fiscal 1997 due to
improved economies of scale related to the significant increase in revenues, and
operating enhancements made to certain acquired operations.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense
increased approximately $4.6 million, or 29.9%, to $20.0 million in fiscal 1998
compared to $15.4 million in fiscal 1997. As a percentage of revenues,
depreciation and amortization expense decreased to 13.9% during fiscal 1998 from
14.8% in fiscal 1997. The decrease in depreciation and amortization expense as a
percentage of revenues was primarily the result of an increase in Casella's
collection operations as a percentage of total revenues in fiscal 1998, which
generally have lower depreciation and amortization expenses than other
operations.

    INTEREST EXPENSE, NET.  Net interest expense increased approximately $2.5
million, or 51.0%, to $7.4 million in fiscal 1998 from $4.9 million in fiscal
1997. This increase primarily reflects increased indebtedness incurred in
connection with acquisitions and capital expenditures.

    OTHER (INCOME) EXPENSE.  Other (income) expense has not historically been
material to Casella's results of operations. However, during fiscal 1997,
Casella established a reserve of $650,000 related to a lawsuit that was settled
for $450,000 in the first quarter of fiscal 1998. Casella also paid $200,000 in
attorneys' fees in connection with such settlement. Additionally, Casella wrote
off $283,000 for recycling facility assets that were deemed to have no value in
the year ended April 30, 1997.

    PROVISION FOR INCOME TAXES.  Provision for income taxes increased
approximately $1.8 million, or 257%, to $2.5 million in fiscal 1998 from
$0.7 million in fiscal 1997. Among the factors causing income tax expense as a
percentage of pre-tax net income to vary materially from year to year are:
(i) the recording of a fixed asset impairment charge in fiscal 1998 which was
non-deductible for income tax purposes and (ii) poolings of interest resulting
in prior period restatements of entities not liable for federal income due to
subchapter S status.

LIQUIDITY AND CAPITAL RESOURCES

    Casella's business is capital intensive. Casella's capital requirements
include acquisitions, fixed asset purchases and capital expenditures for
landfill development, cell construction, and site and cell closure. Casella had
positive net working capital of $3.3 million at April 30, 1999 and $9.5 million
at July 31, 1999, compared to $4.2 million positive net working capital at April
30, 1998.

                                       88
<PAGE>
    Casella has a $150 million revolving line of credit with a group of banks
for which BankBoston, N.A. is acting as agent. This line of credit is secured by
all assets of Casella, including Casella's interest in the equity securities of
its subsidiaries. Subject to the following paragraph, this revolving line of
credit matures in January, 2003. Funds available to Casella under the line of
credit were $77.7 million at April 30, 1999 and $55.6 million at July 31, 1999.

    In connection with the merger with KTI, Casella will be required to replace
its existing credit facility. Although Casella is in the process of negotiating
a new credit facility, there can be no assurance that it will obtain such a
credit facility in the amount, or on the timetable, sought by Casella. In the
event that it is unable to obtain a sufficient credit facility, Casella's
acquisition program, results of operations and financial condition would be
materially and adversely affected. If Casella were unable to obtain a new credit
facility, it will be unable to repay its existing credit facility and will be in
default.

    In July 1998 Casella completed a follow-on public offering of 2,060,587
shares of its Class A Common Stock at $27.25 per share. In addition, as part of
this same offering, 1,470,580 shares of Casella's Class A Common Stock were sold
by certain selling shareholders at $27.25 per share. Casella's proceeds of the
offering, net of underwriters' discounts and issuance costs were $52,231,490.
The proceeds were used for debt reduction, acquisitions and other general
corporate purposes.

    As part of the July 1998 public stock offering Casella registered an
additional 2,000,000 shares of its class A common stock as a `shelf'
registration. The intended use of these additional registered but unissued
shares is as an additional source of capital for Casella's acquisition policy.
As of July 31, 1999, 990,042 shares of Casella's class A common stock had been
issued pursuant to this registration statement.

    Casella believes that its cash provided internally from operations together
with Casella's available credit facilities and anticipated new credit facility
should enable it to meet its needs for working capital for the next twelve
months. In addition, Casella also plans to file a new shelf registration
statement following the KTI merger for use in connection with its acquisition
program.

    Net cash provided by operations was $9.2 million for the three months ended
July 31, 1999 compared to $13.3 million for the same period of the prior fiscal
year. The decrease was primarily due to the decrease in accounts payable and the
increase in accounts receivable due to the extensive growth, partially offset by
the increase in Casella's net income for the three months ended July 31, 1999
over the prior fiscal year, increased depreciation and amortization and
increased closure/post closure accruals.

    Net cash provided by operations for the fiscal years ended April 30, 1999
and April 30, 1998 was $39.6 million and $21.1 million, respectively. The
increase was primarily due to the increase in Casella's net income for the 1999
fiscal year, together with an increase in depreciation and amortization and an
increase in Casella's accrued closure and post closure costs. The increase in
the closure/post closure accrual is due to the completion in the 1998 fiscal
year of work required to close an unlined cell at the Clinton County landfill
and at stage one of Casella's NCES landfill.

    Net cash provided by operations in fiscal 1998 increased to $21.1 million
from $17.3 million in fiscal 1997 primarily due to increases in net income,
depreciation and amortization, asset impairment charges and deferred income tax
provisions, offset by decreases in accrued closure/post closure costs and in
Casella's working capital.

    Cash used in investing activities decreased $0.1 million from $19.8 million
to $19.7 million in the three months ended July 31, 1999 over the same period of
the prior fiscal year. The decrease in investing activities reflects fewer
acquisitions for the quarter ended July 31, 1999 accounted for as purchases,
offset by capital expenditures. For fiscal 1999 and fiscal 1998, cash used in
investing activities was $98.0 million and $61.3 million, respectively. The
increase in investing activities reflected Casella's capital expenditure and
capital needs for acquisitions. Casella's cash needs to fund investing
activities

                                       89
<PAGE>
are expected to increase further as Casella continues to complete acquisitions
and continues to expend capital in order to service internal growth.

    Net cash provided by financing activities was $11.2 million in the three
months ended July 31, 1999 compared to $7.2 million for the same period of the
prior year. The net cash provided by financing activities in the three months
ended July 31, 1999 reflects the borrowings on Casella's credit facility, offset
by repayments. Net cash provided by financing activities in the comparable
period of the prior year reflects the net proceeds of the follow-on offering and
borrowings on Casella's credit facility, offset by repayments.

    For fiscal 1999 and fiscal 1998, Casella's financing activities provided
cash of $59.3 million and $40.7 million, respectively. Net cash provided by
financing activities was $40.1 million in the fiscal year ended April 30, 1997.
The net cash provided by financing activities in the fiscal years ended
April 30, 1999 and 1998 primarily reflects the net proceeds of the public stock
offerings and borrowings on Casella's credit facility, offset by repayments. Net
cash provided by financing activities in fiscal 1997 reflects primarily bank
borrowings and seller subordinated notes, less principal payments on debt.

SEASONALITY

    Casella's revenues have historically been lower during the months of
November through March. This seasonality reflects the lower volume of waste
during the late fall, winter and early spring months primarily because: (i) the
volume of waste relating to construction and demolition activities decreases
substantially during the winter months in the northeastern United States; and
(ii) decreased tourism in Vermont, Maine and eastern New York during the winter
months tends to lower the volume of waste generated by commercial and restaurant
customers, which is partially offset by the winter ski industry. Since certain
of Casella's operating and fixed costs remain constant throughout the fiscal
year, operating income results are therefore impacted by a similar seasonality.
In addition, particularly harsh weather conditions could result in increased
operating costs to certain of Casella's operations.

    Casella's quarterly revenues and operating results have varied significantly
in the past and are likely to vary substantially from quarter to quarter in the
future. Casella establishes its expenditure levels based on its expectations as
to future revenues, and, if revenue levels are below expectations, expenses can
be disproportionately high. Due to a variety of factors including general
economic conditions, governmental regulatory action, acquisitions, capital
expenditures and other costs related to the expansion of operations and services
and pricing changes, it is possible that in some future quarter, Casella's
operating results will be below the expectations of public market analysts and
investors. In such events, Casella's Class A Common Stock price would likely be
materially and adversely affected.

INFLATION AND PREVAILING ECONOMIC CONDITIONS

    To date, inflation has not had a significant impact on Casella's operations.
Consistent with industry practice, most of Casella's contracts provide for a
pass through of certain costs, including increases in landfill tipping fees and,
in some cases, fuel costs. Casella therefore believes it should be able to
implement price increases sufficient to offset most cost increases resulting
from inflation. However, competitive factors may require Casella to absorb at
least a portion of these cost increases, particularly during periods of high
inflation.

    Casella's business is located in the northeastern United States. Therefore,
Casella's business, financial condition and results of operations are
susceptible to downturns in the general economy in this geographic region and
other factors affecting the region such as state regulations and severe weather
conditions. Casella is unable to forecast or determine the timing and/or the
future impact of a sustained economic slowdown.

YEAR 2000 ISSUES

    The approach of the year 2000 has raised concerns about the ability of
information technology systems and non-information technology systems, primarily
computer software programs, to properly recognize and process date-sensitive
information with respect to the Year 2000.

    Casella has undertaken a Year 2000 project, comprised of four phases, to
address these concerns. Phase one, which has been completed, consisted of
awareness, Year 2000 planning, preparing a written plan, management approval and
support. Phase two involved the evaluation of all significant systems and
equipment, including hardware, software, security and voice mail, with respect
to Year 2000 compliance. Phase two was completed on June 30, 1999. Phase three
involved addressing deficiencies identified in Phase two, which was completed on
July 31, 1999. Phase four involved the validation and testing of all systems and
equipment, which has been completed. Casella has performed, and continues to
perform routine updates of all software and hardware systems to facilitate Year
2000 compliance.

    Casella has completed numerous acquisitions in recent months, and the
information systems of these acquired operations have been fully integrated with
Casella's information systems. Casella continues to make acquisitions as an
integral component of its growth strategy. There is no assurance that the
information systems of all acquired operations, particularly those acquisitions
completed in the latter portion of calendar 1999, will be Year 2000 compliant by
December 31, 1999.

    Casella uses well-regarded nationally known software vendors for both its
general accounting applications and industry-specific customer information and
billing systems, and all internal productivity software. Casella has been
informed by the respective vendors that all application software is fully Year
2000 compliant.

    Casella's banking arrangement is with an international banking institution
which has informed Casella that it is taking all necessary steps to insure its
customers uninterrupted service throughout applicable Year 2000 time frames.
Casella's payroll is out-sourced by the largest provider of third-party payroll
services in the country, which has made a commitment of uninterrupted service to
their customers throughout applicable Year 2000 time frames.

    Casella is currently in the process of replacing older personal computers
and servers. There are two servers and 25 additional personal computers that
will be replaced, 16 of which will be for the weight-measurement systems. The
two servers were replaced during the first quarter of fiscal 2000 (ending
July 31, 1999). Casella has acquired a weight-measurement system which it has
been informed is Year 2000 compliant. Currently six beta sites are operational
and Casella is in the process of defining the implementation plan for other
sites. During the implementation, all non Year 2000 compliant hardware is
expected to be replaced.

    Casella conducted a final testing of all systems in the second quarter of
fiscal 2000 and believes it is fully Year 2000 compliant except as set forth
above.

    Casella has expended approximately $1.5 million dollars over the last
eighteen months to address hardware and software-related Year 2000 compliance
issues, principally through the implementation of a new frame network system. A
portion of this investment is attributable to integrating information systems of
companies that Casella has acquired. Casella will use funds from current
operations or Casella's line of credit to meet Year 2000 remediation expenses.

    No single customer represents more than one percent of Casella's revenues,
and we do not expect any material adverse effect on Casella's revenues in the
event an individual customer experiences Year 2000 problems.

    In addition, Casella does not believe the Year 2000 noncompliance of
Casella's suppliers of goods and services, other than as specifically discussed
above, would have a material adverse effect on

                                       91
<PAGE>
Casella's revenues and results of operations. Accordingly, Casella has not
sought assurances of Year 2000 compliance from these other vendors.

    Casella expects to begin its evaluation of its most reasonably likely worst
case scenarios with respect to the Year 2000 in the third quarter of fiscal
2000. Based upon the results of that evaluation, Casella may develop an
appropriate contingency plan.

ADJUSTED EBITDA

    Adjusted EBITDA represents operating income (earnings before interest and
taxes, or "EBIT") plus depreciation and amortization expense and loss on
impairment of long-lived assets. Adjusted EBITDA is not a measure of financial
performance under generally accepted accounting principles, but is provided
because Casella understands that certain investors use this information when
analyzing the financial position and performance of Casella.

                                                 "Multitrade")
</TABLE>

    KTI provides integrated waste handling services, including processing and
recycling of wood, paper, metals, plastic and glass, municipal solid waste
processing and disposal, specialty waste disposal, ash residue recycling and the
manufacturing of finished products using recyclable materials. KTI's business
emphasizes the use of low-cost processing to add value to the waste products
delivered and, in some cases, the generation of electric power and steam.

    KTI operates its business under four reportable segments:

    - waste-to-energy;

    - residential recycling;

    - commercial recycling; and

    - finished products.

    Each reportable segment is a business unit that offers different products or
services. Each is managed separately and provides distinct products or services
using different production facilities.

    The waste-to-energy segment consists of the operations of the following:

    - Maine Energy Recovery Company;

    - Penobscot Energy Recovery Company;

    - Timber Energy Resource's two facilities;

    - Speciality Waste;

    - American Ash Recycling;

    - KTI BioFuels, Inc.;

    - Total Waste Management Corporation (acquired January 1998);

    - Multitrade Group, Inc. (acquired June 1998);

    - Russell Stull (acquired October 1998); and

    - KTI Recycling of Canada (acquired November 1998).

                                       93
<PAGE>
    The residential recycling segment consists of the eighteen facilities that
process and market recyclable materials under long-term contracts with
municipalities and commercial customers which KTI acquired as part of the
acquisition of FCR in August 1998. In addition, the Boston recycling plants
acquired in 1997 are included in this segment.

    The commercial recycling segment consists of the operations of the
following:

    - K-C International (acquired September 1997);

    - KTI Recycling of New Jersey;

    - KTI Recycling of New England; and

    - KTI New Jersey Fibers, which consists of the operations of the following:

       - Gaccione Bros., Inc. & Co. and PGC Corporation (collectively,
         "Gaccione") (acquired August 1998); and

       - Atlantic Coast Fibers, Inc. (acquired August 1998).

These operations process and market paper fibers obtained from commercial
customers and broker paper fibers for KTI's processing facilities and external
customers.

    The finished products segment consists of the operations of the following:

    - Power Ship Transport;

    - Manner (acquired November 1996);

    - the cellulose insulation plants and the plastic reprocessing plants
      acquired with FCR;

    - the plastic reprocessing operations of First State Recycling, Inc.
      (acquired August 1998); and

    - the glass pellet processor Seaglass, Inc. (formed in February 1998 and 80%
      owned by KTI).

These operations manufacture or distribute finished products that use recyclable
materials as their primary raw material.

    KTI evaluates performance and allocates resources based on profit or loss
from operations before interest and income taxes. The accounting policies of the
reportable segments are the same as those described in the summary of
significant accounting policies section of the KTI financial statements. KTI
records intersegment sales at cost plus an agreed-upon profit. Please refer to
the segment reporting information in KTI's notes to consolidated financial
statements.

WASTE-TO-ENERGY SEGMENT

    KTI developed and currently owns majority interests in two waste-to-energy
facilities in Maine. The first facility is an 83.75% owned subsidiary, Maine
Energy, a Maine limited partnership, which is located in Biddeford, Maine. The
other facility is a 70.04% owned subsidiary, Penobscot, a Maine limited
partnership, located in Orrington, Maine. These two facilities use non-hazardous
solid waste from residential, commercial and industrial sources as their source
of fuel.

    A third facility, part of Timber Energy Resources, located in Telogia,
Florida, uses biomass waste as its source of fuel to be combusted for the
production of electricity for sale to the local electric utility. KTI also
operates two wood processing facilities, BioFuels in Lewiston, Maine and Timber
Chip, also a part of Timber Energy Resources, in Cairo, Georgia.

    Total Waste Management operates an emergency response and hazardous waste
site assessment and clean-up business. In addition, it also provides hazardous
and non-hazardous waste management in the New England area.

                                       94
<PAGE>
    Multitrade owns or operates three waste-to-energy facilities in
Martinsville, Virginia. These facilities use biomass and coal to produce steam
for sale to industrial users under long-term contracts.

    Russell Stull is a commercial hauler of non-hazardous waste in the state of
Maine, with revenues of approximately $2.5 million in 1997.

    KTI Recycling of Canada produces crumb rubber from used tires using a
proprietary cryogenic technology in a plant in Ontario.

    On December 28, 1998, the bankruptcy court in Delaware approved a Plan of
Reorganization, which provided for KTI, on the one hand, and Grace
Brothers, Ltd. and SC Fundamental Investments L.P., the majority bond holders of
the Ford Heights, Illinois Waste Tire to Energy project, on the other hand, each
to own 50% of New Heights Recovery & Power, LLC and its facility, which was
built in 1996 at a cost of approximately $110 million for the purpose of
combusting waste rubber to produce electricity. The bondholders converted
$80 million in bonds and other claims into equity in New Heights, and KTI
committed to investing up to $17 million in equity for working capital and
retrofitting and upgrading of the facility.

    KTI holds a 35% stake in Oakhurst Company Inc., which owns two distributors
in the automotive aftermarket. KTI has assigned its interest in and obligations
to New Heights to Oakhurst and agreed to assign KTI Recycling of Canada's
proprietary cryogenic rubber technology to Oakhurst, for use at the New Heights
facility. In return, Oakhurst agreed to purchase an unspecified number of crumb
rubber systems and entered into a royalty agreement with KTI to pay $0.0075
cents per tire processed by Oakhurst using these crumb rubber systems. Oakhurst
also agreed to engage a subsidiary of KTI to be the operating manager of New
Heights and to pay the subsidiary of KTI management fees for each facility
operated.

    KTI has completed the acquisition of AFA Group, Inc., which is now
integrated into its business.

    KTI also owns a 60% limited partnership interest in American Ash Recycling,
a limited partnership that operates a permitted municipal waste combustor ash
recycling facility in Nashville, Tennessee. This facility, which commenced
operations in 1993, is the first commercially operational municipal waste
combustor ash recycling facility in the United States.

    The waste-to-energy segment also engages in other waste management and
processing activities, including commercial hauling, non-hazardous waste
management, ash recycling and tire recycling. These activities are complementary
extensions of the waste-to-energy facilities that enable KTI to provide a wider
range of services to customers and provide strategic opportunities for future
growth through vertical integration.

    MAINE ENERGY POWER PURCHASE AGREEMENT

    The electricity produced by the Maine Energy facility is sold to Central
Maine Power pursuant to the power purchase agreement with Central Maine. Central
Maine serves more than 490,000 customers in an 11,000 square mile service area
in central and southern Maine and purchases substantial amounts of power from
Canadian utilities as well as independent power producers such as Maine Energy.
In 1998, Maine Energy derived approximately $16.1 million, or 54.2% of its
revenues, from the sale of electricity to Central Maine.

    In May 1996, Maine Energy restructured its agreement with Central Maine by
entering into a series of agreements with CL Power Sales One, L.L.C. and Central
Maine that provided for the purchase of Maine Energy's available power
generation capacity by CL Power Sales, and by amending the Central Maine
agreement. CL Power Sales made an initial payment of $85 million and agreed to
make additional quarterly payments through May 31, 2007 to Maine Energy as a
portion of the purchase price and for reimbursement to Maine Energy of certain
expenses. In consideration of its payments to Maine Energy, CL Power Sales was
assigned all rights to capacity from the Maine Energy

                                       95
<PAGE>
facility through May 31, 2007. In the restructuring, the term of the Central
Maine agreement was extended from May 31, 2007 to December 31, 2012. Under its
agreements, Maine Energy has agreed to sell energy to Central Maine through
May 31, 2007 at an initial rate of 7.18 cents per kilowatt-hour ("kWh"), which
escalates annually by 2%. From June 1, 2007 until the expiration date of the
Central Maine agreement, Maine Energy is to be paid market value for both its
energy and capacity by Central Maine.

    Under the terms of the Central Maine restructuring, a $45.0 million letter
of credit was issued to Central Maine by ING (US) Capital Corporation.

    - If, in any year, Maine Energy fails to produce 100,000,000 kWh of
      electricity and Maine Energy does not have a force majeure defense, such
      as physical damage to the plant and other similar events, Maine Energy
      must pay approximately $3.8 million to Central Maine as liquidated
      damages. This payment obligation is secured by the ING letter of credit.
      In each year in which 100,000,000 kWh is produced, the balance of the ING
      letter of credit is to be reduced by approximately $3.8 million.

    - If, in any year, Maine Energy fails to produce 15,000,000 kWh of
      electricity and Maine Energy does not have a force majeure defense, Maine
      Energy must pay the then balance of the ING letter of credit to Central
      Maine as liquidated damages.

    In 1998, the 15,000,000 kWh test was met in February and the 100,000,000 kWh
test was met in August, resulting in a reduction of the amount of the ING letter
of credit by approximately $3.8 million. With respect to 1999, the 15,000,000
kWh test was met in February; however, Maine Energy's past performance is no
indication of its future performance.

    MAINE ENERGY LONG-TERM WASTE HANDLING AGREEMENTS

    Approximately 28% of the municipal solid waste provided to Maine Energy is
delivered pursuant to waste handling agreements with 18 charter municipalities
with terms expiring on June 30, 2007 or later. The agreements are substantially
similar in content except that:

    - 16 charter municipalities are entitled to various concessions as a result
      of having participated in the financial restructuring of Maine Energy in
      1991; and

    - the two "host" charter municipalities of Biddeford and Saco pay tipping
      fees in the amount of one-half of those paid by the other charter
      municipalities.

    Approximately 9.4% of Maine Energy's total revenue in 1998 was attributable
to these long-term waste handling agreements.

    Under the Maine Energy long-term waste handling agreements, each
municipality agrees to deliver acceptable waste to the Maine Energy facility in
an amount equal to its guaranteed annual tonnage. Maine Energy is required to
accept up to 110% of each municipality's guaranteed annual tonnage. A
municipality is required to pay to Maine Energy the tipping fee for the amount
of any shortfall from its guaranteed annual tonnage. As a corollary to the
"put-or-pay" delivery guarantee, each municipality enacted a flow control
ordinance pursuant to Maine law that designates the Maine Energy facility as the
exclusive disposal or reclamation facility to which all acceptable waste
generated within the municipality must be delivered regardless of which entity
picks up waste in such municipality. See "Governmental Regulations--Flow
Control." Each municipality has the right, once a year, to terminate its
long-term waste handling agreement on one year's prior notice.

    PENOBSCOT POWER PURCHASE AGREEMENT

    The Penobscot facility sells the electricity it produces to Bangor Hydro
under a power purchase agreement. Bangor Hydro serves approximately 97,000
customers in a 4,900 square mile service area in

portions of the counties of Penobscot, Hancock, Washington, Waldo, Piscataquis
and Aroostook, Maine. In 1998, Penobscot derived approximately $18.9 million, or
58.7% of its revenues, from the sale of electricity to Bangor Hydro.

    On June 26, 1998 the Bangor Hydro agreement was restructured. Under the
terms of the new power purchase agreement, Bangor Hydro agreed to purchase all
the electricity generated by the Penobscot facility up to 25 megawatts (the
practical limit of the facility's equipment) through 2018. Under the agreement,
Penobscot is required to deliver at least 105,000,000 kWh to Bangor Hydro in any
calendar year. If Penobscot fails to deliver this output, Penobscot must pay
Bangor Hydro $4,000 for each 1,000,000 kWh that the deliveries fall below
105,000,000 kWh. The restructured power purchase agreement did not change this
delivery obligation.

    PENOBSCOT LONG-TERM WASTE HANDLING AGREEMENTS

    As of December 31, 1998, Penobscot had in place 130 long-term waste handling
agreements, of which 85 cover approximately 200 charter municipalities with
terms expiring on March 31, 2018, unless terminated sooner, and all of which are
substantially similar in content. The agreements provide Penobscot with
approximately 195,000 tons per year of municipal solid waste. In addition,
Penobscot receives approximately 18,000 tons per year of municipal solid waste
from municipalities with whom Penobscot has short-term waste handling
agreements, 20,000 tons per year from commercial haulers and 30,000 tons per
year from the spot market. Total waste processing revenues of Penobscot in 1998
were approximately $13.7 million of which approximately 42.9% is attributable to
municipal solid waste received from charter municipalities.

    The Penobscot long-term waste handling agreements with the charter
municipalities are substantially similar to the Maine Energy long-term waste
handling agreements, including the inclusion of guaranteed annual tonnages and
"put-or-pay" provisions and a variable tipping fee for "pass through" and change
in law costs. The performance credit received by each charter municipality may
be used to reduce future tipping fee payments at the option of the charter
municipalities in lieu of cash payment.

    The amended waste disposal agreements generally provide that the charter
municipalities, Bangor Hydro, and partners in Penobscot would each receive
one-third of Penobscot's cash flows. Prior to this amendment, the municipalities
received one-half Penobscot's distributable cash. Based on Penobscot's cash
flow, distributable cash of approximately $4.6 million was payable for 1998 and
approximately $1.1 million for 1997. Of these amounts, approximately
$0.4 million as of December 31, 1998 and approximately $1.1 million as of
December 31, 1997 remained unpaid and was included in accrued expenses.

    On one year's notice, a Penobscot charter municipality may terminate its
long-term waste handling agreement as of March 31, 2000 or March 31, 2002. If
the termination notices received from charter municipalities cause the aggregate
guaranteed annual tonnage of non-terminating municipalities to fall below
180,000 tons, Penobscot may elect to terminate all waste handling agreements
with charter municipalities. No charter municipality has given a termination
notice for March 31, 2000.

    The waste disposal agreements permit the charter municipalities to:

    - make equity contributions to Penobscot, only and to the extent of the
      Municipal Review Committee's share of distributable cash from Penobscot
      and one-half of the Bangor Hydro quarterly payment, of up to
      $31.0 million, which will be used to prepay the outstanding municipal
      bonds (if all $31.0 million is contributed the municipalities will own a
      50% partnership interest in Penobscot);

    - purchase all of the remaining Penobscot interests in 2018 at the then fair
      market value, in lieu of the existing right to purchase Penobscot at its
      then book value in 2004; and

    - extend the term of the waste disposal agreements to 2018.

    TIMBER ENERGY RESOURCES POWER PURCHASE AGREEMENT

    The Telogia facility sells the electricity that it generates to Florida
Power Corporation under a power purchase agreement with Florida Power. Florida
Power serves more than 1.3 million customers in a 20,000 square mile service
area in central and northern Florida. During 1998, approximately 81.6% of the
Telogia facility's revenue was derived from the sale of electricity to Florida
Power, with the majority of the remainder from tipping fees paid by third
parties. Under the power purchase agreement, Florida Power has agreed to
purchase all of the energy generated by the Telogia facility, except for the
energy consumed by the facility.

    CUSTOMERS

    Under the terms of their contracts, Maine Energy must sell all of the
electricity generated at its facilities to Central Maine, Timber Energy
Resources must sell all of its electricity to Florida Power and Penobscot must
sell all of its electricity to Bangor Hydro. The loss of these customers would
have a material adverse affect on the business and financial condition of KTI.

    COMPETITION

    KTI faces significant competition in each of its waste handling markets.
Maine Energy and Penobscot compete with landfills and several waste-to-energy
facilities and municipal incinerators in Maine and the New England region.

    KTI believes that the refuse derived fuel technology employed by the Maine
Energy and Penobscot facilities compares favorably with the mass-burn technology
used by many other waste-to-energy facilities. In refuse derived fuel systems,
municipal solid waste is preprocessed to remove various non-combustible items
that are recycled or landfilled. This results in a significantly reduced volume
of ash residue, thereby lowering ultimate disposal costs, and is also
complementary to current recycling programs.

    The Telogia facility competes for biomass fuel supply with paper companies
that employ on-site power generation. The Telogia facility is permitted to
combust 100% of tipping fee-based fuels. Competition for tipping fee based
material will come principally from landfills whose cost structure is believed
by KTI to be greater than that of the Telogia facility.

    RAW MATERIALS

    The raw material demands of the Penobscot facility currently are met mainly
by Penobscot's long-term waste handling agreements with approximately 200
municipalities in Maine. Penobscot received approximately 75% of its raw
materials in 1998 from these municipalities. Maine Energy received 28% of its
raw materials in 1998 from 18 Maine municipalities under long-term waste
handling agreements and the majority of the balance from commercial and private
waste haulers and municipalities with short-term contracts.

    The Telogia facility uses biomass fuels that are a by-product of the paper
pulp woodchip industry as its raw material. KTI plans to supplement and replace
this raw material with tipping fee based biomass waste, such as construction and
demolition debris and non-recyclable paper products.

    SEASONALITY

    The municipal solid waste market in Maine Energy's and Penobscot's market
areas is seasonal, with one-third more municipal solid waste generated in the
summer months than is generated during the rest of the year.

                                       98
<PAGE>
    EMPLOYEES

    As of September 1, 1999, the waste-to-energy segment had a total of 457
full-time employees. The employees of the Penobscot facility and the Nashville
facility are not KTI employees. The employees of Maine Energy have elected to be
represented by the International Union of Operating Engineers. Negotiations to
enter into a collective bargaining agreement between Maine Energy and the union
began on September 1, 1999. KTI considers its employee relations to be good.

RESIDENTIAL RECYCLING SEGMENT

    The residential recycling segment consists of eighteen facilities that
process and market recyclable materials under long-term contracts with
municipalities and commercial customers. The recyclable materials consist
principally of old newspapers, old corrugated containers, mixed paper and
commingled bottles and cans consisting of steel, aluminum, plastic and glass.

    On August 28, 1998, KTI acquired the stock of FCR. FCR is a diversified
recycling company, headquartered in Charlotte, North Carolina that provides
residential and commercial recycling, processing and marketing services and
manufactures finished products, such as cellulose insulation, using recyclable
materials. FCR owns and operates seventeen material recycling facilities, six
cellulose insulation manufacturing facilities and three plastic reprocessing
facilities located in 12 states. The material recycling facilities are included
in the residential recycling segment while the insulation and plastic facilities
are in the finished products segment. The aggregate purchase price of
approximately $63.6 million consisted of 1,714,285 shares of KTI common stock
and approximately $31.1 million in cash.

    A significant portion of the material provided to the residential recycling
segment is delivered pursuant to long-term contracts with municipal customers.
The contracts generally have a term of five to ten years and these contracts
expire at various times between 1999 and 2018. The terms of each of the
contracts vary but all the contracts provide that the municipality or a third
party deliver materials to KTI's facility. In approximately 41% of the
contracts, the municipalities agree to deliver a guaranteed tonnage and the
municipality pays a fee for the amount of any shortfall from the guaranteed
tonnage. Under the terms of the individual contracts, KTI pays or charges the
municipality a fee for each ton of material delivered. Some contracts contain
revenue sharing arrangements under which KTI pays the municipality a specified
percentage of the revenue from the sale of the recovered materials.

    The residential recycling segment derives a significant portion of its
revenues from the sale of recyclable materials. The resale and purchase prices
of the recyclable materials, particularly newspaper, corrugated containers,
plastic, ferrous and aluminum metals, can fluctuate based upon market
conditions. KTI uses long-term supply contracts with customers with floor price
arrangements to reduce the commodity risk for certain recyclables, particularly
newspaper and aluminum metals. Under such contracts, KTI obtains a guaranteed
minimum price for the recyclable materials along with a commitment to receive
additional amounts if the current market price rises above the floor price. The
contracts are generally with large domestic companies that use the recyclable
materials in their manufacturing process. In 1998, 66% of the revenues from the
sale of recyclable materials of the residential recycling segment were derived
from sales under these long-term contracts.

    COMPETITION

    The residential recycling industry is highly competitive and requires
substantial capital resources and prior experience to bid on municipal
contracts. Competition is both national and regional in nature. Some of the
markets in which KTI competes are served by one or more of the large national
solid waste companies, such as Waste Management, BFI, Allied Waste and Republic
Services, as well as numerous regional and local competitors that offer
competitive prices and quality service.

                                       99
<PAGE>
    RAW MATERIALS

    In 1998, the residential recycling segment received 74.2% of its material
under long-term agreements with municipalities. These contracts generally
provide that all recyclables collected from the municipal recycling programs be
delivered to a facility that is owned or operated by KTI. The quantity of
material delivered by these communities is dependent on the participation of
individual households in the recycling program.

    SEASONALITY

    The residential recycling segment experiences increased volumes of newspaper
in November and December due to increased newspaper advertising and retail
activity during the holiday season. Additionally, the facilities located in
Florida experience increased volumes of recyclable materials during the winter
months followed by decreases in the summer months in connection with seasonal
changes in population.

    EMPLOYEES

    As of September 1, 1999, the residential recycling segment had a total of
690 full-time employees. None of the residential recycling segment's employees
have collective bargaining agreements, and KTI considers its employee relations
to be good.

COMMERCIAL RECYCLING SEGMENT

    The commercial recycling segment processes and markets paper fibers obtained
from commercial customers and brokers paper fibers for KTI's processing
facilities and external customers.

    KTI has merged I. Zaitlin and Sons, Inc., a wholly-owned operating
subsidiary acquired in August 1997, into KTI Recycling of New England, which
remains as the surviving entity.

    On June 4, 1999, KTI sold all of the operating assets of KTI Recycling of
Illinois, Inc. to a third party. KTI Recycling of Illinois operated a facility
located in Chicago, Illinois, which served the low-grade, post-consumer
recycling market.

    COMPETITION

    KTI's waste paper brokerage business and waste paper processing plants face
extensive competition. Principal attributes of these markets contributing to
such competition are industry-wide overcapacity and continual price pressures.

    CUSTOMERS

    The commercial recycling segment processing facilities provide recycling
services to:

    - municipalities;

    - commercial haulers; and

    - commercial waste generators within the geographic proximity of the
      processing facilities.

    KTI acts as a broker of products, including recyclable material processed at
facilities operated by the residential and commercial recycling segments,
principally to paper and box board manufacturers in the United States, Canada,
Pacific Rim countries, Europe and South America.

    RAW MATERIALS

    The raw materials for KTI's commercial recycling segment generally come from
printers and publishing houses and other recyclers and haulers. The waste paper
brokered by KTI is generated

                                      100
<PAGE>
principally from the commercial recycling segment, the New England facility
within the residential recycling segment, from waste generators, and from third
party processors.

    SEASONALITY

    The commercial recycling segment experiences increased quantities of
newspaper and corrugated containers in November and December, followed by
reduced quantities in January, due to increased newspaper advertising and retail
activity during the holiday season.

    EMPLOYEES

    As of September 1, 1999, the commercial recycling segment had a total of 254
full time employees. The employees at KTI New Jersey Fibers in Passaic, New
Jersey are represented by the Laborers' International Union under three separate
collective bargaining agreements. The collective bargaining agreements expire on
dates ranging from February 2000 to November 2000. On July 30, 1999, a vote was
held among the employees of KTI Recycling of New Jersey to determine whether the
employees would be represented by the Laborer's International Union in the
collective bargaining process. The employees voted against representation by the
union, but there can be no assurance that the union will not challenge the
outcome of the vote or that, if challenged, the outcome will be upheld. KTI
considers its employee relations to be good.

FINISHED PRODUCTS SEGMENT

    The finished products segment consists primarily of cellulose insulation
plants and plastic reprocessing plants.

    INSULATION DIVISION

    The insulation division manufactures cellulose insulation, which is
primarily used in the construction of manufactured housing and single family
residential homes. KTI believes it is the second largest producer of cellulose
insulation in the United States and operates six manufacturing facilities
located in Ronda, North Carolina; Tampa, Florida; Phoenix, Arizona; Clackamas,
Oregon; Delphos, Ohio; and Waco, Texas. KTI primarily sells the insulation
produced by the insulation division to the makers of manufactured housing and
insulation contractors throughout the country.

    PLASTICS DIVISION

    The plastics division is a reprocessor of high density polyethylene ("HDPE")
plastics collected primarily from residential recycling programs and industrial
suppliers. The plastics division obtains a majority of its raw materials from
the residential recycling segment. Until August 1998, the plastics division
operated three manufacturing facilities located in Reidsville, North Carolina;
Rockingham, North Carolina; and Hamlet, North Carolina. In August 1998, KTI
closed the Rockingham plant and relocated the equipment to Reidsville and
Hamlet.

    The plastics division has a long-term contract with its largest customer
that expires on August 31, 2000. This contract requires the customer to purchase
a specified quantity of plastic at prices determined by a tolling formula
defined in the contract. Sales to this customer in 1998 represented 47.7% of the
net revenues of the plastics division (11% of total revenues of the finished
products segment). On December 23, 1998 KTI signed a long-term contract with
another significant customer.

    COMPETITION

    The insulation industry is highly competitive and requires substantial
capital and labor resources.

                                      101
<PAGE>
    - In its insulation manufacturing activities, KTI primarily competes with
      manufacturers of fiberglass insulation such as Owens Corning, Certainteed
      and Schuller International. The fiberglass insulation manufacturers
      currently have a significant market share and are substantially better
      capitalized than KTI.

    - The largest producer of cellulose insulation is Louisiana Pacific, a large
      building products manufacturer.

    - KTI believes that it competes with cellulose and fiberglass insulation
      manufacturers by charging competitive prices and offering a quality
      product and excellent customer service support.

    The plastics industry is highly competitive and requires substantial capital
investment in equipment.

    - The plastics division's primary competition comes from other reprocessors
      of recycled plastics, as well as suppliers of virgin HDPE resin. These
      competitors have significantly greater financial and other resources than
      KTI.

    - The plastics division competes primarily by obtaining a guaranteed stream
      of quality raw material from KTI's residential recycling segment. KTI
      believes that it offers competitive pricing because the cost to reprocess
      plastics requires a lower amount of investment in capital than the
      manufacturing of virgin plastic resin and usually sells at a lower price
      per pound. This enables the plastics division to obtain long-term supply
      contracts with customers to ensure a consistent sales volume for its
      facilities.

    KTI also competes with several other recycled plastic brokers and direct
marketing from plastic recycling plants for post-industrial plastic scrap, and
with materials recovery facilities for post-consumer plastics. KTI believes that
it will continue to be competitive because of its knowledge of the plastic
recycling market and its reputation and relationship with its customers.

    CUSTOMERS

    The insulation division sells its products to manufacturers of manufactured
homes, insulation contractors, and retail home improvement stores throughout the
United States. The plastics division sells the majority of its products under
long-term contracts with two customers located adjacent to the KTI facility.

    RAW MATERIALS

    The primary raw material for the insulation division is newspaper collected
from residential recycling programs, including those operated by KTI's
residential recycling segment. In 1998, the insulation division purchased 9.1%
of the newspaper used by it from the residential recycling segment. It purchased
the remaining newspaper from municipalities, commercial haulers, and paper
brokers. The chemicals used to make the newspaper fire retardant are purchased
from industrial chemical manufacturers located in the United States and South
America.

    The plastics division's primary raw materials are baled plastic containers
collected from residential recycling programs, such as those operated by KTI's
residential recycling segment, and ground material from industrial customers. In
1998, the plastics division purchased 53.0% of its raw material from KTI's
residential recycling facilities.

    SEASONALITY

    The insulation division experiences lower sales in November and December
because of lower production of manufactured housing due to holiday plant shut
downs.

    EMPLOYEES

    As of September 1, 1999, the finished products segment had a total of 319
full time employees. None of the finished product segment's employees have
collective bargaining agreements and KTI considers its employee relations to be
good.

LEGAL PROCEEDINGS

    On May 11, 1994, Maine Energy filed a suit in a Maine state court against
United Steel Structures, Inc. under a warranty to recover the costs which were,
or will be incurred to replace the roof and walls of the Maine Energy tipping
and processing building. The judge in the case entered an order awarding Maine
Energy approximately $3.3 million plus interest from May 10, 1994, to the date
of the filing of the lawsuit, and court costs. The defendant filed an appeal on
December 19, 1997. In February 1999, the appellate court reversed the trial
court's verdict in favor of KTI and returned the case to the trial court, which
ordered a new trial.

    On September 30, 1997 and March 6, 1998, Capital Recycling of Connecticut
filed two suits in a Connecticut state court against K-C International, certain
officers of K-C International and other parties. The suits allege fraud,
tortious interference with business expectancy and violations of the Connecticut
Unfair Trade Practices Act. The actions are based on two contracts between
Capital and K-C International. The contracts require all disputes to be resolved
by arbitration in Portland, Oregon. Pursuant to this requirement, K-C
International initiated the arbitration process in Portland, Oregon.
Subsequently, the parties agreed to arbitrate the dispute in Hartford,
Connecticut. The plaintiffs were seeking approximately $1.9 million in damages.
On October 20, 1999, KTI paid Capital $350,000 in final settlement of these
claims.

    On September 30, 1998, the Equal Employment Opportunity Commission filed a
lawsuit against FCR Tennessee, Inc. in the United States District Court for the
Western District of Tennessee, alleging sexual harassment by two managers and a
sexually hostile work environment. The complainants seek compensation for past
and future pecuniary and non-pecuniary losses as well as punitive damages and
potential reinstatement of employment for Valerie L. Jacobs. FCR has retained
counsel to defend this suit and has reported the lawsuit to FCR's director's and
officer's insurance carrier. Management is currently reviewing the lawsuit. The
plaintiffs have demanded $105,000 and KTI has offered $30,000 in settlement. No
agreement on a settlement has been reached. KTI's insurance carrier has agreed
to defend the case.

    On April 1, 1999, William F. Kaiser, a former Executive Vice President and
Treasurer of KTI, filed a lawsuit against KTI in the U.S. District Court for the
District of New Jersey. The suit alleges breach of contract, wrongful
termination, breach of the implied covenant of good faith and fair dealing,
misrepresentation of employment terms and failure to pay wages, all arising out
of Mr. Kaiser's employment agreement with KTI. The suit also alleges that KTI
inaccurately reported its financial results for the first quarter of 1998 and
failed to properly disclose the change of control provision in Mr. Kaiser's
employment agreement. Mr. Kaiser is seeking a declaratory judgment that, upon
closing of the merger, the change of control provision entitles him to receive a
severance payment of two years' salary, in the amount of $320,000, and to
exercise 132,000 unvested options for KTI common stock. Mr. Kaiser is also
seeking damages in the amount of $40,000 for an additional severance payment, as
well as undisclosed damages for outstanding salary, bonus and other payments and
from his sale of approximately 50,000 shares of KTI common stock resulting from
KTI's allegedly inaccurate financial reports.

    On April 6, 1999, Dennis McDonnell filed a lawsuit in a Florida state court
against U.S. Fiber, Inc., a subsidiary of FCR. Mr. McDonnell, a former employee
of U.S. Fiber, seeks a declaratory judgment regarding his rights and obligations
under an employment non-competition agreement and an employment agreement that
he previously had signed with two corporations that subsequently were merged
with and into U.S. Fiber. KTI is defending the suit and believes it has
meritorious defenses.

    On April 15, 1999, C.H. Lee, a former employee of FCR and a former majority
shareholder of Resource Recycling, Inc., commenced arbitration proceedings with
the American Arbitration Association in Charlotte, North Carolina against KTI,
FCR and FCR Plastics, Inc. in connection with the acquisition of Resource
Recycling by FCR. Mr. Lee alleges that FCR and FCR Plastics acted to frustrate
the "earn-out" provisions of the acquisition agreement and thereby precluded
Mr. Lee from receiving, or alternatively, reduced, the sums to which he was
entitled to under the agreement. He also alleges that FCR and FCR Plastics
wrongfully terminated his employment agreement. The claim for

                                      104
<PAGE>
arbitration alleges direct charges in excess of $5.0 million and requests
punitive damages, treble damages and attorneys fees. KTI, FCR and FCR Plastics
responded to the demand, denying liability, and filed a counterclaim for
$1.0 million for misrepresentations. KTI believes it has meritorious defenses to
these claims. If, however, the damages and charges claimed by Mr. Lee are
awarded, KTI's business, financial condition and results of operation could be
materially adversely affected.

    On or about April 26, 1999, Salvatore Russo filed an action in the U.S.
District Court, District of New Jersey against KTI and two of its principal
officers, Ross Pirasteh and Martin J. Sergi, purportedly on behalf of all
shareholders who purchased KTI common stock from May 4, 1998 through August 14,
1998. Melanie Miller filed an identical complaint on May 14, 1999. The
complaints allege that the defendants made material misrepresentations in KTI's
quarterly report on Form 10-Q for the period ended March 31, 1998 in violation
of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended,
concerning KTI allowance for doubtful accounts and net income. The plaintiffs
are seeking undisclosed damages. KTI believes it has meritorious defenses to
these complaints. On June 15, 1999, Mr. Russo and Ms. Miller, together with
Fransisco Munero, Timothy Ryan and Steven Storch, moved to consolidate the two
complaints. This motion is currently pending in the District Court of New
Jersey.

    On July 1, 1999, Michael P. Kuruc filed a demand for arbitration with the
American Arbitration Association in Charlotte, North Carolina, seeking
approximately $1.0 million for compensation due under an employment agreement
that he alleges he has with KTI and losses allegedly suffered in connection with
his sale of KTI common stock. KTI believes that it has meritorious defenses, has
retained counsel to defend this suit and has filed an action to stay the
arbitration in Mecklenburg County Superior Court in North Carolina. On
October 11, 1999, the Superior Court denied KTI's request to stay the
arbitration. If the damages claimed by Mr. Kuruc are awarded, KTI's business,
financial condition and results of operation could be materially adversely
affected.

    Through a newspaper report dated October 19, 1999, KTI learned that the City
Council of Biddeford has authorized the filing of a lawsuit to enjoin the merger
of KTI and Casella. The City of Biddeford has claimed that, under Maine Energy's
waste handling agreements with the City of Biddeford and the City of Saco, KTI
would be required, if the merger is completed, to make a payment to the cities
equal to 20% of Maine Energy's value. The waste handling agreement provides in
part that, in the event that cash proceeds from a capital transaction become
distributable to the partners of Maine Energy (including KTI) on account of the
partners' equity interests, then the Cities (Biddeford and Saco) shall be
entitled to receive a residual cancellation payment equal to their proportionate
share of 20% of such cash distribution. KTI is neither engaging in a capital
transaction relating to Maine Energy, nor receiving cash in the merger. To date
no litigation has been brought. KTI believes it has meritorious defenses to
these claims if litigation is commenced by the City of Biddeford.

    On October 22, 1999, Kyle Trayner filed an action in Putnam Superior Court
in Connecticut against K-C International seeking approximately $400,000
allegedly due for compensation under an employment agreement and for payment on
a promissory note issued by K-C International to Mr. Trayner. KTI believes that
it has meritorious defenses to these claims and intends to retain counsel to
defend this suit.

    KTI is a defendant in certain other lawsuits alleging various claims
incurred in the ordinary course of business, none of which, either individually
or in the aggregate, KTI believes are material to its financial condition,
results of operations or cash flows.

GOVERNMENTAL REGULATION

    GENERAL

    The operations of KTI's waste handling businesses are subject to extensive
governmental regulations at the federal, state, local and provincial levels. KTI
believes that its operations are in material compliance with existing laws and
regulations material to its business. The laws, rules and regulations that
govern the waste handling businesses are very broad and are subject to
continuing change and interpretation. KTI

                                      105
<PAGE>
cannot assure you that it will be able to obtain or maintain the licenses,
permits and approvals necessary to conduct its current business or possible
future expansions of its business. The failure to obtain or maintain requisite
licenses, permits and approvals or otherwise to comply with existing or future
laws, rules and regulations or their interpretations could have a material
adverse effect on the operations of the combined company following the merger.
The following discussions of statutes, regulations and court decisions are brief
summaries, are not intended to be complete and are qualified in their entirety
by reference to such statutes, regulations and court decisions.

    ENERGY AND UTILITY REGULATION

    Each of the Maine Energy facility, the Penobscot facility and the Telogia
facility has been certified by the Federal Energy Regulatory Commission as a
"qualifying small power production facility" under the Public Utility Regulatory
Policies Act of 1978, as amended ("PURPA"). PURPA grants an exemption for
qualifying facilities from most federal and state laws governing electric
utility rates and financial organization. A qualified small power production
facility is exempt from the Public Utility Holding Company Act of 1935 and from
certain state laws and regulations governing electric utility rates and
financial organization. The rates charged by Maine Energy and Penobscot for
acceptance of waste at their facilities are not subject to regulation under
existing state and federal law.

    PURPA requires that electric utilities purchase electricity generated by
qualifying facilities at a price equal to the purchasing utility's full "avoided
cost". Avoided costs are defined by PURPA as the incremental costs to the
utility of electric energy or capacity that the utility would generate itself or
purchase from another source if it could not purchase from the qualifying
facility.

    KTI's waste-to-energy business, which accounted for approximately 42.8% of
KTI's revenue during 1998, is dependent upon electric utilities that purchase
energy produced at KTI's waste-to-energy plants. Under the Central Maine
agreement, the Bangor Hydro agreement and the Florida Power agreement, these
utilities have agreed to purchase electricity generated by the KTI
waste-to-energy facility at contractually agreed rates. Sales of electricity to
these utilities accounted for approximately 54.2% of Maine Energy's, 58.7% of
Penobscot's and 81.6% of the Telogia facility's revenues in 1998. In the event
of the deregulation of electric utilities, certain electric companies may no
longer be financially viable. If the electric utilities with whom KTI has
contracts are adversely impacted by deregulation, the utilities may not be able
to perform their obligations under their purchase power agreements. The State of
Maine has recently enacted deregulation legislation that will require the local
utilities to transfer their contracts with Maine Energy and Penobscot to newly
formed regulated transmission and distribution companies. The costs of the
contracts will be passed through to rate-payers beginning in the year 2000
through these transmission and distribution companies.

    FLOW CONTROL

    From time to time state and local governments have enacted to flow control
ordinances. These ordinances generally require that all waste generated in a
municipality be directed to a specified disposal site. The enactment of flow
control ordinances was authorized by Maine law, and most of the municipalities
that Maine Energy and Penobscot serve enacted such ordinances. From the
municipality's perspective, having the ordinance in place was a corollary to its
agreement to a "put-or-pay" waste handling agreement that requires the
municipality to pay a guaranteed annual minimum fee to the waste-to-energy
facility regardless of the actual amount of municipal solid waste delivered to
the facility.

    In May 1994, in C&A Carbone, Inc. v. Town of Clarkstown, the United States
Supreme Court struck down, as an unlawful violation of the "commerce clause" of
the United States Constitution, a flow control ordinance enacted by the Town of
Clarkstown, New York. KTI does not believe that loss of flow control provisions
would adversely impact operations at either the Maine Energy facility or the
Penobscot facility. The long-term waste handling agreements for such facilities
contractually require the municipalities to pay for waste disposal whether or
not the waste is delivered.

                                      106

    ENVIRONMENTAL LAWS

    While increasing environmental regulation often presents new business
opportunities to KTI, it likewise often results in increased operating costs as
well. KTI strives to conduct its operations in compliance with applicable laws
and regulations, including environmental rules and regulations. This effort
requires programs to promote compliance, such as training employees and
customers, purchasing health and safety equipment, and in some cases hiring
outside consultants and lawyers. Even with these programs, KTI believes that in
the ordinary course of doing business, companies in the environmental services
and waste disposal industry are faced with governmental enforcement proceedings
resulting in fines or other sanctions and will likely be required to pay civil
penalties or to expend funds for remedial work on waste management facilities.

    In March 1999, KTI voluntarily disclosed to civil regulatory authorities at
the Florida Department of Environmental Protection ("FDEP") violations of a
condition of its Clean Water Act waste water discharge permit and related
reporting obligations at its Telogia, Florida facility. On July 28, 1999, KTI
entered into an administrative consent order with FDEP resolving the state civil
aspects of those violations. The violations involved the temperature of the
water discharged from the cooling process. Under the consent order, KTI was
required to pay penalties and expenses totaling $131,000 and must satisfy
certain interim waste water discharge monitoring and reporting requirements,
submit and implement a plan of study for the purpose of obtaining a revised
permit, and either obtain a revised permit or install additional cooling
equipment at the facility. KTI believes it is currently in compliance with the
interim requirements.

    Substantial expenditures could result from governmental proceedings. In
addition, federal, state and local regulators have the power to suspend or
revoke permits or licenses needed for operation of our plants, equipment, and
vehicles or any of our operating subsidiaries based on its compliance record.
Also, customers may decide not to use a particular disposal facility or do
business with a company because of concerns about its compliance record.
Suspension or revocation of permits or licenses would have a negative impact on
our business and operations and could have a material adverse impact on our
financial results.

    KTI's waste-to-energy, ash recycling and wood processing business activities
at its facilities and its transportation and waste disposal business activities
are regulated pursuant to federal, state and local environmental laws. Federal
laws such as the Clean Air Act of 1990 as amended, and the Clean Water Act and
their state analogs govern discharges of pollutants from waste-to-energy
facilities to air and water, and other federal, state and local laws such as the
Resource Conservation and Recovery Act of 1976, as amended ("RCRA"),
comprehensively govern the generation, transportation, storage, treatment and
disposal of solid waste. These environmental regulatory laws, and others such as
the Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended ("CERCLA"), may make KTI potentially liable in the event of
environmental contamination associated with its activities, facilities or
properties.

    The environmental regulatory laws and regulations or licenses and permits
issued thereunder also establish operational standards, including specific
limitations on emissions of certain air and water pollutants. Failure to meet
these standards could subject the facilities to enforcement actions and, unless
excused by particular circumstances, fines or other liabilities.

    Standards established pursuant to the environmental regulatory laws and
governmental policies governing their enforcement may change. For example, new
technology may be required or stricter standards may be established for the
control of discharges of air or water pollutants or for solid waste or ash
handling and disposal. Such future developments could affect the manner in which
KTI operates its facilities and could require significant additional capital
expenditures to achieve compliance with such requirements or policies and other
environmental remediation laws may subject KTI to strict joint and several
liability for the costs of remediating contamination associated with
contaminated sites, including landfills, at which there has been disposal of
residue or other waste handled, transported or processed by KTI and real
property owned by KTI that may be contaminated.

                                      107
<PAGE>
    Applications have been made for the air emissions permits for the Maine
Energy, Penobscot and Telogia facilities. Under Maine regulatory law, a permit
continues in effect provided that a timely application for renewal is made. In
Maine Energy's case, the application was submitted in compliance with state
mandate during August 1996. In December 1996, a public hearing was held by the
Maine Department of Environmental Protection on the application and to address
the favorable results of an independently conducted health risk assessment
pertaining to Maine Energy.

    In the case of Penobscot, a renewal application was submitted in advance of
the deadline. Penobscot is awaiting notification from the state of Maine to
finalize approval of the air emission permit.

    KTI believes that the Maine Energy, Penobscot and Telogia facilities are in
compliance with the federal Clean Air Act, its implementing regulations and all
other applicable regulations and, therefore, KTI anticipates that the permits
will be renewed following the hearings. There can be no assurance, however, that
new conditions will not be imposed in the permits or that the permits will be
renewed.

    In City of Chicago v. Environmental Defense Fund, a case interpreting
provisions of RCRA, the United States Supreme Court determined that the
generation of ash residue from waste-to-energy facilities in the incineration
process is not exempt from hazardous waste regulation. The ash produced at the
Maine Energy, Penobscot and the Telogia facilities is typically tested for
hazardous wastes and has generally met the requirements of non-hazardous
material according to the regulations implementing RCRA promulgated by the
Environmental Protection Agency since their adoption. Any ash residue that is
designated as hazardous material is disposed of according to regulations
governing the disposal of such material. Moreover, KTI's ash residue is disposed
in landfills segregated to accept ash residue only, and, to KTI's knowledge, the
landfill facilities at which the ash residue is disposed meet or exceed the
applicable standards for such facilities under RCRA. Further, KTI has been
indemnified by Waste Management of Maine, Inc. with respect to potential
environmental liabilities relating to ash residue delivered for disposal by
Maine Energy. There can be no assurance, however, that the current regulations
governing the testing and disposition of ash residue will not be modified and
made more stringent and require operational or technological adjustments at the
Maine Energy, Penobscot and the Telogia facilities, which adjustments could have
a material adverse effect on the operation of such facilities and the financial
viability or profitability of the combined company.

    Maine Energy's waste handling agreements with its host communities of
Biddeford and Saco prescribe a set of standards for noise, odor and ash
emissions from the Maine Energy facility and impose penalties in the event of
non-compliance. Since the Maine Energy facility is sited directly in the
commercial area of Biddeford, KTI has implemented stringent operational
practices to mitigate the escape of odors from the Maine Energy facility
including the use of air lock doors at the waste-hauling trucks' entrance to,
and exit from, the facility's tipping floor.

    KTI's Total Waste Management subsidiary is involved in the transportation of
both liquid and solid waste. Total Waste Management is a hazardous waste
transporter and operates both a hazardous waste and a special waste transfer
facility at its Newington, New Hampshire site. Total Waste Management also
operates a 700,000 gallon used oil processing and marketing facility at the
Newington site.

STOCK OWNERSHIP OF MANAGEMENT

    The following table sets forth information, as of September 1, 1999,
regarding the beneficial ownership of KTI common stock by (a) each person or
entity known to KTI to beneficially own more than five percent of KTI common
stock; (b) each director; (c) the chief executive officer and the four other
most highly compensated executive officers of KTI as of December 31, 1998; and
(d) all current directors and executive officers of KTI as a group.

                                      108
<PAGE>
    Beneficial ownership is determined in accordance with rules of the SEC, and
includes generally voting power and/or investment power with respect to
securities. Shares of common stock subject to options and/or warrants currently
exercisable or exercisable within 60 days of September 1, 1999 are deemed
outstanding for computing the percentage beneficially owned by the person
holding the options and/or warrants but are not deemed outstanding for purposes
of computing the percentage beneficially owned by any other person. Except as
indicated by footnote, KTI believes that the persons named in this table, based
on information provided by these persons, have sole voting and investment power
with respect to the shares of common stock indicated.

    CURRENT EMPLOYMENT AGREEMENTS

    KTI's employment agreement with Martin J. Sergi provided for his employment
as president of KTI. This employment agreement will be terminated upon the
effectiveness of the merger, and will be replaced with the employment agreement
described above under "The Merger--Interests of executive officers and directors
of Casella and KTI in the merger." Mr. Sergi's annual base salary was increased
from $185,000 to $210,000, effective as of May 1996, and from $210,000 to
$250,000 effective as of August 1998. Prior to the most recent amendment,
Mr. Sergi was entitled to a bonus of 2% of pre-tax consolidated net income of
KTI and its subsidiaries of between $3,000,000 and $4,000,000; 4% of pre-tax
consolidated net income of KTI and its subsidiaries between $4,000,001 and
$5,000,000; and 6% of pre-tax consolidated net income of KTI and its
subsidiaries over $5,0000,000. Mr. Sergi was entitled to a bonus of
approximately $500,000 for 1996 under the formula in his employment agreement
with KTI. Pursuant to a letter agreement with the KTI board, this bonus was
reduced to $145,000. For 1997, Mr. Sergi was entitled to a bonus of
approximately $120,000, but Mr. Sergi waived receipt of this bonus. Currently,
Mr. Sergi was to receive a bonus based on the attainment of certain goals set by
the KTI board. The agreement also provided that Mr. Sergi would participate in
any employee benefit plans established for senior management of KTI, that he is
entitled to payments not in excess of $700 per month as an automobile allowance,
that KTI will pay premiums for $250,000 of term life insurance on his life and
that he will be entitled to participate in a disability plan maintained by KTI.
KTI also agreed that Mr. Sergi will be entitled to participate in an incentive
stock option plan for senior management.

    KTI agreed with Mr. Sergi that if his employment terminated other than by
reason of his death, retirement, disability or for cause, or if he should elect
to terminate his employment as a result of "good reason," he would be entitled
to continue receiving his annual base salary for a period of three years and
would also be entitled to receive payment of an amount intended to compensate
him for retirement benefits he would have received had he remained in KTI's
employ until retirement. "Good reason" is defined to mean, among other things,
(a) the assignment to the employee of materially different duties than those
existing at the commencement of the agreement or which require travel
significantly more time consuming than that required at the commencement of the
agreement and (b) the reduction of employee's authority as a senior executive
officer. However, Mr. Sergi may not terminate the employment agreement for
reasons specified in clause (a) above more than six months following a
"change-of-control" of KTI, as defined in the employment agreement.

    KTI's employment agreement with Ross Pirasteh provided for his employment as
the chairman and a member of the executive committee of the KTI board. This
employment agreement will be terminated upon the effectiveness of the merger and
will be replaced with the employment agreement described above under "The
Merger--Interests of executive officers and directors of Casella and KTI in the
merger." Mr. Pirasteh's annual base salary is $250,000, and he was entitled to a
bonus in an amount determined by the compensation committee of the KTI board.
The agreement also provided that Mr. Pirasteh would participate in any employee
benefit plans established for senior management of KTI, that he was entitled to
all fringe benefits and perquisites generally available to senior management of
KTI, that KTI would pay premiums for $250,000 of term life insurance on his life
and that he would be entitled to participate in a disability plan maintained by
KTI. KTI has also agreed that Mr. Pirasteh would be entitled to participate in
an incentive stock option plan for senior management.

    KTI agreed with Mr. Pirasteh that if his employment terminates other than by
reason of his death, retirement, disability or for cause, or if he should elect
to terminate his employment as a result of "good reason," he would be entitled
to receive an amount equal to three times the sum of (i) his highest annual base
salary prior to termination and (ii) the higher of his most recent bonus or 50%
of his base salary at the time of termination, and would also be entitled to the
benefits he would have received had he remained in KTI's employ for a period of
three years. "Good reason" is defined to mean, among other things, (a) the
assignment to the employee of duties inconsistent with those existing

                                      111
<PAGE>
at the commencement of the agreement or which require travel significantly more
time consuming than that required at the commencement of the agreement, (b) the
material alteration of employee's responsibilities and (c) a "change-of-control"
of KTI, as defined in the employment agreement.

    COMPENSATION OF DIRECTORS

    In 1998, KTI paid each non-employee director a fee of $12,500 per annum. In
1997 and 1996, KTI paid each non-employee director a fee of $7,500 per annum.
Non-employee directors also participate in the KTI, Inc. Directors' Stock Option
Plan pursuant to which non-employee directors are granted a nonstatutory stock
option to purchase up to 7,500 shares of KTI common stock on the date of each
annual meeting of shareholders. Employee directors currently do not receive an
additional fee for their services as directors.

(1) In 1998, Mr. Sergi was granted 25,000 options under KTI's incentive option
    plan. Of the 25,000 options granted in 1998, 6,000 are incentive stock
    options and 19,000 are nonstatutory options. The additional 75,000 options
    granted in 1998 were nonstatutory, non-plan options. In 1998, Mr. Pirasteh
    was granted 25,000 options under KTI's incentive option plan. Of the 25,000
    options granted in 1998, 6,000 are incentive stock options and 19,000 are
    nonstatutory options. The additional 75,000 options granted in 1998 were
    nonstatutory, non-plan options. The options granted to Messrs. Sergi and
    Pirasteh under the plan vest in 60 equal monthly installments with full
    vesting to occur after five years. The non-plan options were fully vested on
    the date of grant.

(2) Options were granted at the fair market value determined as of the date of
    the grant, based upon the last reported sale price of KTI common stock on
    the Nasdaq National Market.

(3) Amounts reported in these columns represent amounts that may be realized
    upon exercise of the options immediately prior to the expiration of their
    term assuming the specified compound rates of appreciation (5% and 10%) on
    the market value of KTI common stock on the date of the option grant over
    the term of the options. These numbers are calculated based on rules
    promulgated by the SEC and do not reflect KTI's estimate of future stock
    price growth. Actual gains if any, on stock option exercise and KTI common
    stock holdings are dependent on the timing of the exercise and the future
    performance of KTI common stock. There can be no assurance that the rates of
    appreciation assumed in this table can be achieved or that the amounts
    reflected will be received by the individuals.

    COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    During the fiscal year ended December 31, 1998, Paul Kleinaitis, Jack Polak
and Wilbur Ross served on KTI's compensation committee. No member of the
compensation committee was involved in an interlocking relationship or insider
participation with respect to the compensation committee.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

    KTI leases office space from the Mall at the Galaxy, Inc., a corporation
that is 72% owned by Martin J. Sergi, a principal shareholder and president of
KTI. The mall leases space to 27 tenants under long-term operating leases. KTI
made rental payments to the mall of $96,000 in fiscal year 1998. KTI believes
that the lease for the office space was made on terms comparable to those which
could have been obtained from an unaffiliated lessor.

    KTI held a promissory note of the Mall at the Galaxy, Inc. dated January 1,
1994 in the original principal amount of $121,581, with a balance including
interest accrued as of December 31, 1998 of $62,486. This note was issued in
replacement of a note dated May 30, 1989 in the original principal amount of
$74,076. The note bears interest at 10% per annum. KTI believes that this note
was issued on terms comparable to those which could have been obtained from an
unaffiliated lessor.

    During 1996, KTI made private placements of $2,003,314 of 8% notes due
July 31, 1996 together with 333,882 warrants to purchase KTI common stock at
$6.00 per share, subject to adjustment, which expire five years from the date of
issue. In this private placement, Mr. Pirasteh purchased $60,000 in notes and
10,500 warrants, which were registered in the names of others. KTI believes that
the terms on which Mr. Pirasteh received securities in this private placement
are comparable to those which were obtained from unaffiliated investors
concurrently with Mr. Pirasteh's investments.

                    KTI MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

    The following is a discussion of certain factors affecting KTI's results for
the three and six months ended June 30, 1999, and the three fiscal years in the
period ended December 31, 1998, as well as our liquidity and capital resources.
When used in this discussion, the terms "we" and "our" refer to KTI or its
management. This discussion should be read in conjunction with our historical
financial statements and notes, which can be found on pages F-1 to F-128.

    We are a holding company and derive our earnings from our subsidiaries.
During 1998 and the first six months of 1999, as part of our integrated waste
management strategy, we acquired several businesses and additional partnership
interests. As a result of the acquisitions completed in 1998, we began reporting
the results of operations by the following four segments: waste-to-energy,
residential recycling, commercial recycling and finished products.

    Our municipal solid waste disposal operations are subject to seasonal
fluctuations due to less waste being generated during the winter months because
of seasonal changes in population, which impacts our revenues. The
waste-to-energy facilities also have scheduled shutdowns each year, usually two
weeks in April or May, for major maintenance and capital projects.

    In June 1998, we refinanced Penobscot's outstanding bonds. As a result,
Bangor Hydro Electric Company, which purchases the power from Penobscot, made a
one-time payment of $6.0 million in cash, issued a non-interest bearing note due
in 16 quarterly payments of $250,000 commencing on October 1, 1998 and issued
warrants to our subsidiary to purchase 713,000 shares of Bangor Hydro common
stock. Pursuant to the amended power disposal agreement, Bangor Hydro is
entitled to receive a one-third share of Penobscot's distributable cash.

    The $6.0 million payment, the present value of the Bangor Hydro payments,
approximately $3.6 million, and the warrant valuation of approximately
$3.8 million were recorded as a customer advance. The customer advance, net of
transaction costs, is being amortized over the life of the Power Purchase
agreement with Bangor Hydro. Pursuant to the amended power disposal agreement,
Bangor Hydro is entitled to receive a one-third share of Penobscot's
distributable cash.

    The residential recycling facilities also generate revenues from the sale of
recyclable materials, which revenues fluctuate with the changes in the market
price. We use long-term supply contracts with floor price arrangements to
minimize commodity risk for certain recyclables. Under these contracts, we
obtain a guaranteed minimum price for the recyclable materials as well as with a
commitment to receive additional amounts if current market prices rise above the
floor price.

    The operations of our commercial recycling segment have continued to be
below our expectations because of low volumes in our processing plants, reduced
brokerage volumes as a result of the economic downturn in the Pacific Rim, and
lower commodity prices that have reduced profit margins.

    Our acquisition of FCR in August 1998 provided us with a new line of
business, the manufacturing of finished products that use recyclable materials
as a primary raw material. The insulation division manufactures cellulose
insulation which is used primarily in the construction of manufactured housing
and single family residential homes in six plants located throughout the
country. The plastics division is a reprocessor of plastics collected primarily
from residential recycling programs and industrial suppliers in two plants
located in North Carolina. The plastics division also brokers post-industrial
and post consumer plastics.

    On July 19, 1996, DataFocus, one of our wholly owned subsidiaries, executed
an agreement with CIBER, Inc. Under the agreement, DataFocus sold substantially
all of the assets of its business systems division, other than cash and accounts
receivable, to CIBER for $5.0 million, subject to customary purchase price
adjustments. DataFocus retained cash, accounts receivables and substantially all
of the liabilities of its business systems division that arose before July 26,
1996. The net proceeds of this sale, including cash and accounts receivable
retained, less related liabilities, were approximately $4.3 million.

    Additionally, on July 29, 1996, we sold our stock in DataFocus to certain
members of the management of DataFocus. Pursuant to the sale, we received $5,000
in cash, the cancellation by DataFocus management of stock options for 132,328
shares of our common stock, the cancellation of an option to purchase 20% of the
common stock of DataFocus and a royalty agreement. We received royalties of
$60,000 in 1998 and 1997. A loss from discontinued operations of approximately
$0.7 million for the year ended December 31, 1996 resulted from the sale and
disposal of our computer service division.

REVENUES

    Consolidated revenues for the three and six months ended June 30, 1999 were
$64.8 million and $130.9 million, respectively. Compared with the same periods
in 1998, consolidated revenues increased $30.0 million or 86.2% and
$58.3 million or 80.2%, respectively.

    WASTE-TO-ENERGY SEGMENT

    Total revenues for this business unit were approximately $25.4 and
$49.0 million for the three and six months ended June 30, 1999, respectively,
compared to approximately $17.3 and $35.8 million, respectively, for the same
periods in 1998. This represents an increase of approximately $8.1 million or
46.8% and $13.2 million and 36.9% for the three and six months ended June 30,
1999, respectively, compared to the same periods in 1998.

    Revenues in the waste-to-energy segment are primarily derived from waste
processing and electric power sales. Total tons received by the waste-to-energy
facilities increased by 5.0% and 4.2% for the three and six months ended
June 30, 1999, respectively, compared to the same periods in 1998. The tons
received at Penobscot increased approximately 3.3% and 0.2% for the three and
six months ended June 30, 1999, respectively, compared to the same periods in
1998. This increase at Penobscot was a result of the scheduled plant shutdown
occurring during the first quarter in 1999. In 1998, Penobscot's scheduled plant
shutdown occurred in the second quarter. The tons received by American Ash
Recycling increased approximately 79.9% and 81.3% for the three and six months
ended June 30, 1999, respectively compared to the same periods in 1998. The
increases at the American Ash facility were partially offset by a 3.8% and 4.4%
decrease in tons at Maine Energy for the three and six months ended June 30,
1999, respectively, compared to the same periods in 1998. The decrease at Maine
Energy was due to lower production as a result of repairs to the primary
processing equipment.

    Waste processing revenues increased by approximately $2.8 million or 31.1%
and approximately $3.8 million or 22.4% for the three and six months ended
June 30, 1999, respectively, compared to the same periods in 1998. This increase
in revenue is a result of the net increase in tonnage discussed above, increased
prices charged per ton during 1999 compared to 1998 of approximately 7.2% and

                                      118
<PAGE>
additional revenues from the Multitrade, Russell Stull, AFA Group and KTI
Recycling of Canada acquisitions. The increases from the acquisitions were
offset by reductions at KTI BioFuels due to the elimination of brokerage
operations on March 31, 1998.

    Electric power revenues for the three and six months ended June 30, 1999
increased approximately $0.5 million or 3.9% and approximately $1.4 million or
4.1% compared to the same periods in 1998. The increase in revenues is due to
amortization of the customer advance at Penobscot and additional revenues from
Multitrade which was acquired in June 1998. This was offset by higher
performance credits as a result of the amended Power Purchase and Waste Disposal
Agreements.

    RESIDENTIAL RECYCLING SEGMENT

    This segment, which includes the residential recycling plants of FCR and the
KTI Recycling of New England facilities in Boston posted revenues of
approximately $6.0 million and $15.1 million for the three and six months ended
June 30, 1999, respectively, compared to approximately $1.5 and $3.2 million,
respectively, for the same periods in 1998. This increase of approximately $4.5
and $11.9 million, respectively, is a result of the acquisition of FCR being
completed in the third quarter of 1998.

    COMMERCIAL RECYCLING SEGMENT

    The commercial recycling segment had total revenues for the three and six
months ended June 30, 1999 of approximately $19.3 and $40.4 million,
respectively, compared to $13.5 and $29.5 million, respectively, for the same
periods in 1998. This represents an increase of approximately $5.8 and
$10.9 million, respectively. These increases are primarily as a result of the
acquisition of KTI New Jersey Fibers, Inc., which was completed in the third
quarter of 1998, and higher commodity prices for paper fibers in the second
quarter of 1999 compared to the second quarter of 1998. These increases were
partially offset by lower volumes at the commercial processing plants due to the
sale of the KTI Recycling of Illinois facility in Chicago.

    FINISHED PRODUCTS SEGMENT

    Total revenues for this segment for the three and six months ended June 30,
1999 were approximately $14.1 and $26.4 million, respectively, compared to
approximately $2.5 and $4.2 million for the same periods in 1998. This
represents an increase of approximately $11.5 and $22.2 million, respectively.
The increase in revenues is primarily the result of acquisitions discussed above
and higher volumes at Manner. These volumes were partially offset by decreases
in plastic prices in the second quarter of 1999 compared to the same period in
1998.

COSTS AND EXPENSES

    WASTE-TO-ENERGY SEGMENT

    Cost of operations in this segment consists primarily of electric power and
waste handling costs which were approximately $20.8 and $37.7 million, during
the three and six months ended June 30, 1999, respectively, compared to
approximately $16.5 and $29.2 million, respectively, for the same periods in
1998. This is an increase of approximately $4.3 million or 26.1% and
$8.5 million or 29.1%, respectively. The increase was primarily a result of the
Total Waste Management, Multitrade, Russell Stull, AFA Group and KTI Recycling
of Canada acquisitions discussed above which had total costs of operations of
approximately $5.4 million for the six months ended June 30, 1999. In addition,
Penobscot's operating costs decreased 5.3% due to lower costs associated with
the planned plant shutdown. Timber Energy Resources costs decreased by 12.5% as
a result of an increase in tipping fee based material which reduced fuel costs
and the elimination of the costs associated with the KTI BioFuels brokerage
discussed above.

                                      119
<PAGE>
    RESIDENTIAL RECYCLING SEGMENT

    Cost of operations in this segment for the three and six months ended
June 30, 1999 was approximately $6.3 and $14.8 million, respectively, compared
to approximately $1.3 and $2.5 million, respectively, for the same periods in
1998. This was because of our acquisition of FCR in the third quarter of 1998.

    COMMERCIAL RECYCLING SEGMENT

    Cost of operations in this segment for the three and six months ended
June 30, 1999 was approximately $23.2 and $44.1 million, respectively, compared
to approximately $14.1 and $29.8 million, respectively, during the same periods
in 1998. This increase is primarily due to our acquisition of KTI New Jersey
Fibers in August 1998 and higher commodity purchase prices which were partially
offset by lower volumes at the commercial processing plants.

    FINISHED PRODUCTS

    Cost of operations in this segment for the three and six months ended
June 30, 1999 was approximately $15.1 and $26.7 million, respectively, compared
to approximately $2.6 and $3.9 million, respectively, during the same periods in
1998. The increase was primarily a result of the acquisitions discussed above
and increased volumes at Manner. The increased volumes at Manner were partially
offset by lower purchase prices in 1999.

OTHER ITEMS

    Selling, general and administrative expenses increased by approximately $4.2
and $9.0 million for the three and six months ended June 30, 1999, respectively,
compared to the same periods in 1998. The increase is a result of selling,
general administrative costs added through acquisitions throughout 1998 and the
addition of administrative staff to develop and install corporate-wide
information systems; to develop and support a formal strategic planning and
budgeting process; to support company-wide credit and collection efforts; to
identify and pursue potential mergers and acquisitions; and to develop internal
information systems to identify revenue enhancement and cost savings programs in
newly acquired entities.

    On June 1, 1999, KTI completed the sale of its Chicago commercial recycling
facility and recorded a loss of approximately $0.4 million.

    As a result of this loss, KTI initiated an impairment review of the
long-lived assets, including goodwill, in the commercial recycling segment. A
revised operating plan for each of the remaining facilities in the commercial
recycling segment was developed. While revenues are stable, the commercial
recycling segment continues to operate at levels of profitability which are
significantly below the levels anticipated when the acquisitions were completed.
In addition, with the continued consolidation of the solid waste industry and
the continued focus on the disposal aspects of this industry, the possibility of
selling these facilities for amounts approximating their carrying value is
remote.

    KTI continued to experience low operating results in the commercial
recycling segment and determined that the estimated future undiscounted cash
flows for the KTI Recycling of New Jersey facility in Newark were below the
carrying value of the long-lived assets. KTI adjusted the carrying value of the
equipment and leasehold improvements of the Newark facility by approximately
$3.0 million to their estimated fair value of approximately $1.2 million. The
fair value of the long-lived assets was based on the expected cash flows
discounted at a rate commensurate with the risk involved.

                                      120
<PAGE>
    Interest expense increased approximately $3.8 and $6.0 million during the
three and six months ended June 30, 1999, respectively, compared to the same
periods in 1998. These increases are related principally to increased borrowings
on KTI's line of credit to fund several acquisitions, incremental interest
expense on debt assumed as part of these acquisitions, higher interest rates on
KTI's line of credit, fees associated with the amendment of financial covenants,
and the conversion of the Series B Preferred Stock to convertible debt. These
increases were partially offset by lower interest rates at Penobscot as a result
of the refinancing of the bonds payable and lower debt levels at Maine Energy.

    YEAR ENDED DECEMBER 31, 1998 COMPARED WITH YEAR ENDED DECEMBER 31, 1997

REVENUES

    Consolidated revenue for the year ended December 31, 1998, compared with the
same period in 1997, increased approximately $80.4 million or 81.6%.

                                      121
<PAGE>
    WASTE-TO-ENERGY SEGMENT

    The total revenues for the waste-to-energy segment were approximately
$76.7 million for the year ended December 31, 1998, compared to approximately
$74.2 million for the same period in 1997. This is an increase of approximately
$2.5 million or 3.4%.

    Revenues in the waste-to-energy segment were primarily produced from waste
processing and electric power sales. Total tons received by Maine Energy and
Penobscot increased 2.0% and 4.1%, respectively, in 1998, compared to 1997.
These increases were due to higher municipal solid waste disposal rates in the
areas close to the facilities, which improved the competitive pricing position
for Maine Energy and Penobscot. Waste processing revenues decreased by
approximately $2.0 million or 8.3% for the year. This decrease was due to higher
performance credits due to the restructuring of the Bangor Hydro power purchase
agreement. This decrease was reduced by an approximately 5.0% increase in the
prices charged per ton during 1998 versus 1997 and additional revenues from the
Total Waste Management acquisition, offset by a 12.2% decrease in volume versus
1997 as a result of lower volumes at Timber Energy Resources' Cairo facility.

    Electric power revenues increased about $8.0 million or 20.4% during the
year. Revenue for the year increased due to the restructuring of the Bangor
Hydro power purchase agreement in the second quarter. In connection with the
restructuring of the Bangor Hydro power purchase agreement, we received
$6.0 million in cash and an agreement from Bangor Hydro to pay us $250,000 per
quarter over the next four years, a total of $4.0 million. Bangor Hydro also
issued warrants to purchase one million shares of Bangor Hydro common stock to
the partners of Penobscot. Our share, which was based upon our ownership
percentage at Penobscot, was approximately 713,000 warrants. The estimated fair
market value of these warrants at the date of issue was $5.35 per warrant. The
$6.0 million in cash, the present value of the payments from Bangor Hydro of
approximately $3.6 million, and the fair value of the warrants of approximately
$3.8 million were recorded as a customer advance and are being amortized over
the life of the Bangor Hydro power purchase agreement. The amount recorded as
revenue for the year ended December 31, 1998 was $0.5 million. The remaining
increase in revenues resulted from the acquisition of Multitrade, the 3%
increase in the price per kilowatt hour charged during 1998, and the 1% increase
in kilowatt hours as a result of a shorter down period for Timber Energy
Resources' Cairo Facility in 1998.

    RESIDENTIAL RECYCLING SEGMENT

    This segment includes the residential recycling plants of FCR. This segment
posted revenues of approximately $11.8 million for 1998. This segment had no
revenues for the same period in 1997 because the acquisition was completed in
1998.

    COMMERCIAL RECYCLING SEGMENT

    Total revenue for this segment for the year ended December 31, 1998 was
approximately $68.1 million compared to $17.7 million for the same period in
1997. This is an increase in sales of approximately $50.4 million compared to
the same period in 1997. The increase in revenues is primarily the result of a
full year of operations in 1998 compared to five months of operations for K-C
International and six weeks of operations for KTI Recycling of Illinois, KTI
Recycling of New England and KTI Recycling of New Jersey in 1997, and the KTI
New Jersey Fibers acquisitions. These increases were partially offset by lower
commodity prices for paper fibers in 1998.

    FINISHED PRODUCTS SEGMENT

    Total revenue for this segment for the year ended December 31, 1998 was
approximately $22.3 million compared to approximately $6.5 million for the same
period in 1997. This represents an increase of approximately $15.8 million. The
increase in revenues primarily resulted from the

                                      122
<PAGE>
acquisitions discussed above, which were partially offset by lower revenues at
Manner due to decreases in plastic prices in 1998.

COSTS AND EXPENSES

    WASTE-TO-ENERGY SEGMENT

    Cost of operations in this segment was approximately $59.1 million during
the year ended December 31, 1998, compared to approximately $54.4 million during
1997. This represents an increase of approximately $4.7 million or 8.6%. The
increase was primarily a result of the Total Waste Management and Multitrade
acquisitions discussed above, which had total costs of operations of
approximately $5.3 million. These increases were offset by a decrease in costs
at Timber Energy Resources of approximately $1.1 million. Timber Energy
Resources incurred additional costs during 1997 due to an extended shutdown at
its Telogia Facility.

    RESIDENTIAL RECYCLING SEGMENT

    Cost of operations in this segment was approximately $10.4 million for 1998.
We acquired the FCR facilities during 1998.

    COMMERCIAL RECYCLING SEGMENT

    Cost of operations in this segment for the year ended December 31, 1998 was
approximately $68.6 million in 1998 compared to approximately $17.2 million in
1997. This represents an increase of approximately $51.4 million compared to the
same period in 1997. This increase is due primarily to the acquisition of KTI
New Jersey Fibers in August 1998 as well as the inclusion of K-C International
and the KTI Recycling of Illinois, KTI Recycling of New England and KTI
Recycling of New Jersey facilities for a full year in 1998 compared to five
months of operations for K-C International and six weeks of operations for each
of the Illinois, New England and New Jersey facilities in 1997.

    FINISHED PRODUCTS

    Cost of operations in this segment for the year ended December 31, 1998 was
approximately $21.5 million compared to approximately $6.4 million in 1997. The
increase was primarily a result of the acquisitions discussed above and was
partially offset by lower purchase prices at Manner due to decreases in plastics
prices in 1998.

OTHER ITEMS

    Selling, general and administrative expenses increased by approximately
$4.8 million during 1998 compared to 1997. Other than costs added through recent
acquisitions, we have added administrative staff to develop and install
corporate-wide information systems; to develop and support a formal strategic
planning and budgeting process; to support company-wide credit and collection
efforts; to identify and pursue potential mergers and acquisitions; and to
develop internal analytical systems to identify revenue enhancement and cost
savings programs in newly acquired entities.

    Interest expenses increased approximately $5.6 million or 109.7% during 1998
compared to the same periods in 1997. These increases are principally related to
increased borrowings on our line of credit in order to fund several
acquisitions, the conversion of the Series B Preferred Stock to convertible
debt, and the premium of approximately $1.4 million on the conversion of the
debt to equity. These increases were partially offset by lower interest rates at
Penobscot because of the refinancing of the outstanding bonds and lower debt
levels at Maine Energy.

    The income tax benefit was approximately $3.0 million for 1998 compared to
approximately $2.6 million in 1997. The income tax benefit includes a credit of
approximately $3.2 million in 1998 and $5.1 million in 1997, due to the reduced
valuation allowance for deferred tax assets as a result of the determination
that we will be able to utilize net operating loss carryforwards.

                                      123
<PAGE>
    The extraordinary loss represents the loss on early retirement of the
Penobscot bonds of approximately $0.4 million net of minority interest and
income tax benefits.

    YEAR ENDED DECEMBER 31, 1997 COMPARED WITH YEAR ENDED DECEMBER 31, 1996

REVENUES

    WASTE-TO-ENERGY

    Revenue increased by approximately $38.5 million during the year ended
December 31, 1997 compared to 1996. The net increase was a result of both
increased sales of approximately $30.8 million and the consolidation of
Penobscot for financial reporting purposes during 1997, which includes
approximately $23.6 million of revenues from the period prior to the date we
acquired our controlling interest in Penobscot, and approximately $4.5 million
for a full year effect of certain acquisitions during 1997.

    COMMERCIAL RECYCLING

    Sales of recyclables increased to approximately $24.2 million in 1997 as a
result of acquiring I. Zaitlin & Sons, K-C International and the KTI Recycling
of Illinois, KTI Recycling of New England and KTI Recycling of New Jersey
facilities in 1997.

COSTS AND EXPENSES

    WASTE-TO-ENERGY

    Electric power waste handling operating costs increased by approximately
$28.3 million, for the year ended December 31, 1997 compared to 1996. The
increase was a result of consolidation of Penobscot in 1997, which led to costs
and expenses of approximately $17.8 million in 1997, which includes
approximately $13.1 million of costs and expenses from the period prior to the
date we acquired our controlling interest in Penobscot, and a full year effect
of certain acquisitions.

    COMMERCIAL RECYCLING

    The approximately $23.6 million increase in recycling costs was primarily
caused by the 1997 acquisitions of K-C International, Zaitlin and the KTI
Recycling of Illinois, KTI Recycling of New England and KTI Recycling of New
Jersey facilities, as well as the inclusion of Manner for the entire year of
1997 compared to only one month in 1996. These costs primarily reflect the costs
of acquired recyclables for resale.

OTHER ITEMS

    Expenses related to sales, administrative and general items increased by
approximately $0.7 million or 26.1% for the year ended December 31, 1997
compared to 1996. This increase was primarily caused by salaries of additional
management personnel and associated expenses resulting from the acquisitions of
K-C International, Zaitlin and the KTI Recycling of Illinois, KTI Recycling of
New England and KTI Recycling of New Jersey facilities in 1997, as well as the
inclusion of Timber Energy Resources and Manner for a full year in 1997 compared
to only five weeks for 1996.

    Depreciation and amortization for the year ended December 31, 1997 increased
by approximately $2.7 million or 40.4% compared to 1996. The increase resulted
from the consolidation of Penobscot in 1997, which includes approximately $3.0
million of depreciation and amortization from the period prior to the date we
acquired our controlling interest in Penobscot, and the full year effect in 1997
of certain acquisitions, offset by a decrease in depreciation at Maine Energy
due to the full year effect of the change in estimated useful lives of property,
plant and equipment beginning in the fourth quarter of 1996.

                                      124
<PAGE>
    Interest, net increased by approximately $0.6 million or 13.9% for the year
ended December 31, 1997 compared to 1996. This increase resulted from
consolidating Penobscot, which includes approximately $2.2 million of interest
from the period before the date when we acquired our controlling interest, and
including a full year of interest for acquisitions during the fourth quarter of
1996. These increases were partially offset by a decrease in interest expense as
a result of the repayments of $64.5 million in outstanding bonds and
$29.5 million in subordinated debt at Maine Energy and a continued reduction in
our outstanding debt.

    Equity in net income of Penobscot was eliminated as a result of the
consolidation of Penobscot for 1997. Pre-acquisition minority earnings of
approximately $4.6 million for the nine month period ended September 30, 1997
are included in minority interest in 1997.

    Loss on sale of investments in 1996 was related to sales of securities in
connection with the early retirement of debt at Maine Energy. None of these
transactions occurred in 1997.

    The tax benefit of approximately $2.6 million in 1997 is the result of a
reduction in our valuation allowance on net deferred tax assets. Our ability to
use our net operating loss carry forwards is limited as discussed below. The tax
benefit recorded in 1997 is based on management's evaluation that we will be
able to use all net operating loss and alternative minimum credit carry forwards
that are available to offset 1998 and 1999 income.

LIQUIDITY AND CAPITAL RESOURCES

    We are a holding company and receive a portion of the cash flows of our
subsidiaries. Receipt of cash flow from Penobscot is currently restricted by
covenants under loan agreements, distribution restrictions under partnership
agreements with Penobscot's equity investors, and put-or-pay agreements with
municipalities. Maine Energy's cash flow is required to retire the remaining
outstanding subordinated debt balance of approximately $11.5 million as of
June 30, 1999 before partners' cash distributions can begin (approximately
$7.6 million of these notes are owned by KTI). Timber Energy Resources' cash
flow is restricted by covenants under its bond agreements. As a result, the
following discussion is organized to present liquidity and capital resources of
KTI separate from Maine Energy, Penobscot and Timber Energy Resources and
liquidity and capital resource of each of Maine Energy, Penobscot and Timber
Energy Resources independently.

    We operate in industries that require high levels of capital investment. Our
capital requirements basically stem from (i) our working capital for ongoing
operations, (ii) capital expenditures for new plants and equipment and
(iii) business acquisitions. Our strategy has been to meet these capital needs
from internally generated funds that are not contractually restricted, drawings
under our lines of credit, collateralized equipment financing and proceeds from
the sale of our common stock.

    As of June 30, 1999, KTI was in default of the financial covenants of its
$150.0 million line of credit. KTI's lender has waived the violation of the
financial covenants through January 1, 2000. As a result of the default, the
outstanding amount under the line of credit has been classified as a current
liability as of June 30, 1999. Upon the consummation of the merger, this line of
credit will be replaced by the credit facility of the combined company. However,
no assurances can be given that the conditions of the merger will be satisfied
or that the merger will be consummated.

    If the merger is not consummated, KTI will be required to modify the
financial covenants or obtain an additional waiver from the lender. The lender
is under no obligation to amend the financial covenants or provide such a
waiver. KTI management believes that KTI will either obtain an additional waiver
or an amendment to the financial covenants; however, there can be no assurances
that this can be accomplished. As of June 30, 1999, no funds were available to
KTI under its revolving credit agreement. Though KTI management believes that
cash flows from its subsidiaries will meet its current needs for working capital
and capital expenditures, KTI's ability to expand its current operations is

                                      125
<PAGE>
dependent on cash flow from its subsidiaries. We believe that KTI has the
ability to access additional facilities to fund capital expenditures if needed;
although no assurance can be given in this regard.

    As of June 30, 1999, one of KTI's subsidiaries was in violation of the
financial covenants of its revolving line of credit. KTI believes that these
violations were cured as of October 31, 1999. Upon the consummation of the
merger, this line of credit will be replaced by the credit facility of the
combined company. We cannot assure you that the conditions of the merger will be
satisfied or the merger will be consummated.

    As of June 30, 1999, as a result of a reclassification of the outstanding
balance under the Revolving Credit Agreement, we had a working capital deficit
of approximately $107.3 million (ratio of current assets to current liabilities
of 0.46:1) and a cash balance of approximately $5.4 million which compared to
working capital of approximately $42.8 million (a ratio of current assets to
current liabilities of 2.11:1) and a cash balance of approximately $9.4 million
at December 31, 1998. As of June 30, 1999, we had a working capital deficit and
cash on hand without regard to Maine Energy, Penobscot and Timber Energy
Resources of approximately $137.7 million (a ratio of current assets to current
liabilities of 0.28:1) and approximately $1.6 million, respectively, which
compared to working capital of approximately $12.9 million (a ratio of current
assets to current liabilities of 1.41:1) and a cash balance of approximately
$3.9 million at December 31, 1998.

    Our ability to make future acquisitions depends on our ability to increase
our line of credit. Our ability to increase the line of credit is dependent on
our ability to raise additional equity or raise capital from financial
instruments that are subordinated to the KeyBank credit line. We believe that we
have the ability to raise additional capital if needed; however, there can be no
assurance that this can be accomplished at terms and conditions that would be
acceptable to us.

    As of June 30, 1999, we and our subsidiaries, other than Maine Energy,
Penobscot and Timber Energy Resources, had current maturities of indebtedness of
approximately $155.3 million (including the reclassified debt), including
borrowings under revolving credit facilities. During the six months ended
June 30, 1999, we, apart from Maine Energy, Penobscot and Timber Energy,
increased net borrowings on our lines of credit by approximately $12.4 million,
primarily for the refinancing of debt assumed from acquisitions, the funding of
business operations and capital expenditures.

    MAINE ENERGY

    Maine Energy has financed its operations and capital expenditures from cash
flows from operations. Cash provided by operations was approximately
$0.1 million for the six months ended June 30, 1999 compared to approximately
$1.2 million during the same period in 1998. Maine Energy's capital expenditures
were approximately $1.0 million and $1.7 million during the six months ended
June 30, 1999 and 1998, respectively.

    As of June 30, 1999 and December 31, 1998, Maine Energy had operating cash
of approximately $0.3 million and $2.4 million, respectively, and as required
under the terms of the credit agreement underlying its letter of credit, Maine
Energy has on account an additional approximately $5.5 million and
$6.0 million, respectively, of reserves to be used under certain circumstances
for capital improvements, debt service, operating shortfalls and working capital
requirements. As of June 30, 1999, Maine Energy had total indebtedness of
approximately $11.5 million.

    We believe Maine Energy's cash flows from operations and cash resources
available will be sufficient to fund anticipated capital expenditures and debt
service requirements. Capital expenditures for Maine Energy for the remainder of
1999 are not expected to be significant.

                                      126
<PAGE>
    PENOBSCOT

    Penobscot has financed its operations and capital expenditures primarily by
cash flow from operations. Cash provided by operations was approximately
$2.7 million for the six months ended June 30, 1999 compared to approximately
$5.9 million in the same period in 1998. Penobscot's capital expenditures were
approximately $1.3 million and $0.2 million during the six months ended
June 30, 1999 and 1998, respectively.

    On June 26, 1998, we completed a major restructuring of the various
contracts and obligations of Penobscot, which included refinancing Penobscot's
tax exempt bonds. The refinancing was made possible by the sale of approximately
$45.0 million in Electric Rate Stabilization Revenue Refunding Bonds issued by
Finance Authority of Maine. The proceeds, and certain funds from operations were
used to repay the outstanding Revenue Bonds. The interest rate on the bonds
ranges from 3.75% for one-year bonds to 5.20% for 20-year term bonds. The
refinancing will reduce Penobscot's debt service costs while extending its
payment obligation over 20 years.

    As of June 30, 1999, in addition to Penobscot's operating cash of
approximately $2.8 million, Penobscot, as required under the terms of the trust
indenture governing the FAME Bonds, had on account an additional approximately
$15.4 million of cash reserves to be used for capital improvements, debt
service, operating shortfalls and working capital requirements.

    We believe Penobscot's cash flows from operations and cash resources
available will be sufficient to fund anticipated capital expenditures and debt
service requirements. Penobscot plans capital expenditures for the remainder of
1999 of approximately $0.4 million, which has largely been set aside in the
reserve accounts.

    TIMBER ENERGY RESOURCES

    Timber Energy Resources has financed its operations and capital expenditures
primarily by cash flows from operations. Cash provided by operations was
approximately $0.7 million for the six months ended June 30, 1999 compared to
approximately $0.8 million during the same period in 1998.

    Timber Energy Resources has two 1997 Industrial Development Revenue Bond
issues outstanding that carry interest at a fixed rate of 7% and have annual
sinking fund payments due each December 1 with a final payment due December 1,
2002. As of June 30, 1999, Timber Energy Resources had $11.6 million outstanding
in 1997 Bonds.

    As of June 30, 1999 and December 31, 1998, in addition to Timber Energy
Resources' operating cash of approximately $0.7 million and $0.8 million,
respectively, Timber Energy Resources, as required under the terms of its
then-existing debt agreements, had on account approximately $1.8 and
$2.1 million, respectively, of reserves to be used under certain circumstances
for capital improvements, debt service, operating shortfalls and working capital
requirements.

    We believe Timber Energy Resources' cash flows from operations and cash
resources available will be sufficient to fund anticipated capital expenditures
and debt service requirements. We expect capital expenditures for Timber Energy
Resources for the remainder of 1999 to be approximately $0.2 million. Timber
Energy Resources intends to finance the requirements through cash flow from
operations.

TAX LOSS CARRYFORWARDS

    At June 30, 1999, we had net operating loss carryforwards of approximately
$55.4 million for income tax purposes that expire in years 2002 through 2018 and
are subject to the limitations described below. In addition, we have general
business credit carryforwards of approximately $0.5 million that expire in the
years 1999 through 2006 and alternative minimum tax credit carryforwards of
approximately $0.9 million that are not subject to limitation.

                                      127
<PAGE>
    The Tax Reform Act of 1986 enacted a complex set of rules limiting the
potential utilization of net operating loss and tax credit carryforwards in
periods following a corporate "ownership change." In general, for federal income
tax purposes, an ownership change occurs if the percentage of stock of a loss
corporation owned, actually, constructively and, in some cases, deemed, by one
or more "5% shareholders" increases by more than fifty (50) percentage points
over the lowest percentage of such stock owned during a three-year testing
period.

    During 1994, we had such a change in ownership. As a result of the change,
our ability to use our net operating loss carryforwards and general business
credits will be limited to approximately $1.2 million of taxable income, or
approximately $0.4 million of equivalent credit per year. This limitation may be
increased if we recognize a gain on the disposition of an asset that had a fair
market value greater than its tax basis on the date of the ownership change.

    In connection with the acquisition of Timber Energy Resources, FCR and Total
Waste Management, we recorded net operating loss carryforwards of approximately
$25.6 million, $12.5 million and $0.5 million, respectively, which are included
in the total of $55.4 million in loss carryforwards and which are also subject
to a corporate "ownership change". As a result of the change, our ability to use
the net operating loss carryforwards related to these entities is limited to
approximately $1.0 million, $3.2 million and $0.1 million, respectively, per
year.

ENVIRONMENTAL CONTINGENCIES

    While increasing environmental regulation often presents new business
opportunities to us and our subsidiaries, it likewise often results in increased
operating costs as well. We and our subsidiaries strive to conduct our
operations in full compliance with applicable laws and regulations, including
environmental rules and regulations. This effort requires programs to promote
compliance, such as training employees and customers, purchasing health and
safety equipment, and in some cases hiring outside consultants and lawyers. Even
with these programs, we believe that in the ordinary course of doing business,
companies in the environmental services and waste disposal industry face
governmental enforcement proceedings resulting in fines or other sanctions and
will likely be required to pay civil penalties or to expend funds for remedial
work on waste management facilities.

    In March 1999, KTI voluntarily disclosed to civil regulatory authorities at
the Florida Department of Environmental Protection ("FDEP") violations of a
condition of its Clean Water Act waste water discharge permit and related
reporting obligations at its Telogia, Florida facility. On July 28, 1999, KTI
entered into an administrative consent order with FDEP resolving the state civil
aspects of those violations. The violations involved the temperature of the
water discharged from the cooling process. Under the consent order, KTI was
required to pay penalties and expenses totaling $131,000 and must satisfy
certain interim waste water discharge monitoring and reporting requirements,
submit and implement a plan of study for the purpose of obtaining a revised
permit, and either obtain a revised permit or install additional cooling
equipment at the facility. KTI believes it is currently in compliance with the
interim requirements.

    As of June 30, 1999, no pending governmental environmental enforcement
proceedings exist for which we or any of our subsidiaries believe that potential
monetary sanctions will exceed $0.1 million. The possibility always exists that
substantial expenditures could result from governmental proceedings, which would
have a negative impact on our earnings for a particular reporting period. More
importantly, federal, state and local regulators have the power to suspend or
revoke permits or licenses needed for the operation of our or our subsidiaries'
plants, equipment, and vehicles based on the applicable company's compliance
record, and customers may decide not to use a particular disposal facility or do
business with a company because of concerns about its compliance record.
Suspension or revocation of permits or licenses would negatively impact our
business and operations and could have a material adverse impact on our
financial results.

                                      128
<PAGE>
INFLATION

    Inflation has had a minimal effect on our operating costs in the past three
years. Most of our operating expenses are inflation sensitive, with increases in
inflation generally resulting in increased costs of operation. The effect of
inflation-driven cost increases on each of our project's overall operating costs
is not expected to be greater for such projects than for our competitor's
projects. In addition, each of Maine Energy's and Penobscot's contracts and the
majority of our residential recycling contracts allow us to increase waste
processing fees paid by municipal customers annually based on inflation.

YEAR 2000 ISSUE

    Year 2000 compliance is the ability of computer hardware and software to
respond to the problems posed by the fact that computer programs have
traditionally been written using two digits rather than four to define the
applicable year. As a consequence, unless modified, computer systems will not be
able to differentiate between the year 2000 and 1900. Systems must also
recognize the Year 2000 as a leap year. Failure to address this problem could
result in system failures and the generation of erroneous data. This could
potentially impact our ability to perform our obligations under long-term
contracts, which could result in legal and other liabilities that would have a
material adverse effect.

    We are in the process of contacting our customers and vendors and have
received letters from each of our applications vendors stating that the majority
of our information technology systems, such as accounting, data processing,
plant operations systems and telephone/PBX systems, are Year 2000 compliant.
Several insignificant software applications that represent 20% of our
applications are not Year 2000 compliant. We plan to replace or upgrade these
applications with compliant versions by the end of the third quarter of 1999. We
have also begun an assessment of our non-information technology systems, such as
our security systems and telephones, to determine if they are Year 2000
compliant. We plan to initiate formal communications with the vendors of our
remaining non-information technology systems. Based on our assessment to date,
we believe that our non-information technology systems will be Year 2000
compliant prior to the Year 2000.

    We have also begun an assessment of our significant vendors, suppliers, and
service providers to determine the extent to which we are vulnerable to those
third parties' failure to remediate their own Year 2000 compliance issues. To
date, we believe, based on information published or otherwise provided by the
third parties, that all of their systems are or will be Year 2000 compliant. We
plan to initiate formal communications with significant remaining third parties.
Based on our assessment to date, we believe that our significant vendors,
suppliers and service providers will be Year 2000 compliant prior to the Year
2000.

</TABLE>

    We have also conducted tests of all of our internal information and
non-information technology systems and all of our system interfaces with
significant vendors, suppliers and service providers to ensure Year 2000
compliance. All of our accounting and data processing equipment is based on
microcomputer hardware and related software. 80% of this equipment has been
certified as Year 2000 compliant by the applicable manufacturer or developer.
However, we have determined that the plant control systems may contain embedded
technology that is not Year 2000 compliant. These control systems were replaced
by Year 2000 compliant systems. However, despite our efforts to ensure that our
internal systems and the systems of our significant vendors, suppliers and
service providers are Year 2000 compliant, we cannot guarantee that the failure
of certain systems will not have a material adverse effect on us.

    To date, we have used internal resources to reprogram or replace, test, and
implement the software and hardware modifications for Year 2000. Our only costs
have been the salary costs of our internal staff of four. To date, we have
incurred approximately $0.1 million (30% expensed and 70% capitalized for new
systems and equipment), related to all phases of the Year 2000 project. We
estimate that the remaining project costs will be less than $0.1 million for the
purchase of new software and hardware and approximately $0.1 million of internal
resources. Although we currently expect to be able to complete our Year 2000
compliance program using only internal resources, we cannot guarantee that we be
able to do so.

    The most significant risk identified by us is the inability of the power
plants to generate electric power. We have received assurances that the process
control systems will be Year 2000 compliant with the installation of new
hardware components. We performed a complete test of the systems during the
planned shutdown periods that were completed during the third quarter of 1999.
In addition, we have developed contingency plans for this risk as well as other
internal and external applications which involve manual workarounds, increasing
inventories and adjusting staffing strategies. This risk could cause a default
under our power purchase agreements with customers or a loss of electric power
revenue. We are unable to reasonably estimate the impact of this risk; however,
there can be no guarantee that this risk will not have a material adverse effect
on us. We also cannot guarantee that we have identified all the significant
risks associated with Year 2000 compliance.

RECENT ACCOUNTING PRONOUNCEMENTS

    Recent accounting pronouncements that are not required to be adopted as of
June 30, 1999, include the following Statement of Financial Accounting Standards
("SFAS") and the American Institute of Certified Public Accountants Statements
of Position ("SOP"):

    SFAS No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES,
which we will be required to adopt as of January 1, 2001, establishes standards
for derivative instruments including those embedded in other contracts and for
hedging activities. The new standard requires us to recognize all derivatives as
either assets or liabilities and measure those instruments at fair value. We
believe that the adoption of SFAS No. 133 will not have a material impact on our
financial statements.

    SOP 98-1, ACCOUNTING FOR COSTS OF COMPUTER SOFTWARE DEVELOPED OR OBTAINED
FOR INTERNAL USE will be required to be adopted by us as of January 1, 2000. Our
current policy falls within the guidelines of SOP 98-1.

QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK

    KTI currently utilizes no material derivative financial instruments which
expose it to significant market risk. KTI is exposed to cash flow and fair value
risk due to changes in interest rates with respect to its debt. The table below
presents principal cash flows and related weighted average interest rates of the
KTI's debt at June 30, 1999 by expected maturity dates. Weighted average
variable rates are based on forward rates in United States Government Treasury
Constant Maturities at June 30, 1999. Forward rates should not be considered a
predictor of actual future interest rates.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION

    The following unaudited pro forma combined financial statements give effect
to the merger under the purchase method of accounting. These pro forma
statements are presented for illustrative purposes only. The pro forma
adjustments are based upon available information and certain assumptions that
management believes are reasonable. The pro forma combined financial statements
do not purport to represent what the results of operations or financial position
of Casella would actually have been if the merger had in fact occurred on such
dates, nor do they purport to project the results of operations or financial
position of Casella for any future period or as of any date. Additionally, no
pro forma adjustments have been made to reflect potential effects of (a) the
efficiencies that may be obtained by combining the operations of Casella and KTI
or (b) the costs of restructuring, integrating or consolidating the operations
of Casella and KTI, except as disclosed in Note 4(g). Under the purchase method
of accounting, tangible and identifiable intangible assets acquired and
liabilities assumed are recorded at their estimated fair values. The excess of
the purchase price, including estimated fees and expenses related to the merger,
over the fair value of net tangible assets acquired has preliminarily been
allocated to goodwill, and is being amortized over an estimated blended life of
30 years. The estimated fair values and useful lives of assets acquired and
liabilities assumed are based on a preliminary valuation and are subject to
final valuation adjustments.

    Casella's and KTI's fiscal years end on different dates. Accordingly, to
combine Casella's and KTI's financial information:

    - The unaudited pro forma combined condensed balance sheet information as of
      July 31, 1999 was prepared by combining the balance sheet at July 31, 1999
      for Casella, with certain adjustments, with the balance sheet at June 30,
      1999 for KTI, giving effect to the merger as though it had been completed
      on July 31, 1999;

    - The unaudited pro forma combined condensed statements of operations for
      the three months ended July 31, 1999 was prepared by combining Casella's
      statement of operations for the three months ended July 31, 1999, with
      certain adjustments, with KTI's statement of operations for the three
      months ended June 30, 1999, giving effect to the merger as if it had
      occurred on May 1, 1998; and

    - The unaudited pro forma combined condensed statement of operations for the
      year ended April 30, 1999 was prepared by combining Casella's statements
      of operations for the year ended April 30, 1999, with certain adjustments,
      with KTI's statements of operations for the twelve months ended March 31,
      1999, as adjusted for an acquisition and the sale of substantially all
      assets of a business, giving effect to the merger as if it had occurred on
      May 1, 1998.

    The unaudited pro forma financial information should be read in conjunction
with the respective audited historical financial statements, the unaudited
interim financial statements and the notes thereto of Casella and KTI which we
included in this proxy statement/prospectus.

NOTE 4. PURCHASE PRICE ALLOCATION

    The fair value of the consideration to acquire KTI's common stock will be
allocated to the assets and liabilities of KTI based on their estimated fair
value. A preliminary allocation is presented below in which the fair value of
the identifiable net assets are assumed to equal the net book value of such
assets, as adjusted, more fully described in (d) below. The excess of
consideration over the fair value of the identifiable net assets has been
preliminarily allocated to goodwill as follows (in thousands, except share and
per share data):

(d) Casella and KTI expect to enter into a new line of credit agreement
    immediately following the consummation of the merger. Therefore, deferred
    financing fees of $1.9 million on KTI's June 30, 1999 balance sheet have
    been given no value in the combined unaudited pro forma balance sheet. When
    the new line of credit has been obtained, current liabilities of $150
    million will convert to long term obligations.

(e) A pro forma adjustment has been made for the three months ended July 31,
    1999 and the twelve months ended April 30, 1999 to reflect the amortization
    of acquired intangibles using an estimated blended life of 30 years.

(f) KTI had deferred revenue related to certain contracts that is not considered
    an assumed liability to the combined company.

(g) A pro forma adjustment has been made as of June 30, 1999 to reflect
    estimated incremental liabilities related to planned divestitures of KTI
    assets and other matters following the merger. The incremental liabilities
    can be summarized as follows:

       --  $3.5 million estimate related to facility abandonment charges,
           including residual waste material clean-up and disposal costs, lease
           termination fees and miscellaneous other charges. Of these charges,
           $1.5 million relates to residual waste material clean-up and disposal
           costs that will be incurred by certain KTI businesses which are not
           expected to be sold.

       --  $1.0 million estimate related to employee severance and separation
           costs, and employment contract early termination costs.

    No pro forma adjustments have been made to the statement of operations to
    reflect the impact of these proposed asset divestitures because the
    estimated impact is immaterial. In addition, the foregoing pro forma
    adjustments relate only to certain planned divestitures expected to occur
    shortly following the merger and do not include adjustments associated with
    divestitures of the remainder of the 10 to 15 percent of KTI assets planned
    to be divested. No pro forma adjustments have been made with respect to such
    additional planned divestitures because plans relating to those divestitures
    are preliminary at this time.

NOTE 5. REVENUE

    A pro forma adjustment has been made for the three months ended July 31,
1999 and the twelve months ended April 30, 1999 to eliminate previously
recognized revenue relative to the deferred revenue discussed in Note 4 (f).

           KTI UNAUDITED ADJUSTED HISTORICAL STATEMENT OF OPERATIONS

    The KTI unaudited adjusted historical statement of operations for the twelve
months ended March 31, 1999 and the three months ended June 30, 1999 include the
effect of KTI's acquisition of FCR on August 28, 1998 and KTI's sale of
substantially all the assets of KTI Recycling of Illinois, Inc. on June 1, 1999,
as if the acquisition and sale had occurred on April 1, 1998. This acquisition
was accounted for under the purchase method of accounting and accordingly, the
results of operations since the acquisition date is included in the historical
financial statements of KTI.

    The KTI unaudited adjusted historical statement of operations is not
necessarily indicative of the results of operations which would have been
reported if the acquisition and sale had occurred on April 1, 1998, nor is it
necessarily indicative of the future operating results of the combined company.
Furthermore, the adjusted historical statement of operations does not give
effect to all cost savings or incremental costs that may occur as a result of
the integration and consolidation of the completed acquisition. In the opinion
of management, all adjustments necessary to present fairly such adjusted
historical statement of operations have been made.

    The KTI unaudited adjusted historical statement of operations should be read
in conjunction with the historical consolidated financial statements of KTI
which we have included elsewhere in this proxy statement/prospectus.

       NOTES TO KTI UNAUDITED ADJUSTED HISTORICAL STATEMENT OF OPERATIONS
                                 (IN THOUSANDS)

1. DESCRIPTION OF TRANSACTIONS

    On August 28, 1998, KTI, Inc. (KTI) acquired FCR, Inc. (FCR) for $30.0
million in cash, and issued 1,714,285 shares of KTI common stock.

    On July 2, 1998, FCR acquired Resource Recovery Systems, Inc. (RRS).

    All the acquisitions discussed above were accounted for under the purchase
method of accounting and accordingly, the results of operations since the
respective acquisition dates are included in the historical financial statements
of KTI.

    On June 1, 1999, KTI sold substantially all the assets of KTI Recycling of
Illinois, Inc. (Illinois) for $1.8 million in cash.

    The KTI unaudited adjusted historical statement of operations is not
necessarily indicative of the results of operations which would have been
reported if the acquisitions or the sale of Illinois had occurred on April 1,
1998, nor are they necessarily indicative of the future operating results of the
combined company. Furthermore, the adjusted historical statement of operations
do not give effect to any cost savings or incremental costs that may occur as a
result of the integration and consolidation of the completed acquisitions. In
the opinion of management, all adjustments necessary to present fairly such
adjusted historical statement of operations have been made.

    The KTI unaudited adjusted historical statement of operations should be read
in conjunction with the historical consolidated financial statements of KTI,
which we included in this proxy statement/ prospectus.

2. PRO FORMA ADJUSTMENTS

(1) Reduction in depreciation expense resulting from the reduction in carrying
    value of acquired assets based on purchase price allocation of $49.
    Depreciation is recorded over the estimated remaining lives of property,
    plant, and equipment.

(2) Reflects additional goodwill amortization expense of $22. Goodwill is
    amortized over 40 years.

(3) Adjustment to interest expense on refinanced and incremental debt
    outstanding, assuming an average interest rate of 8.85%.

(4) Provision (benefit) for income taxes on the pro forma adjustments at a 39.5%
    tax rate before non-deductible depreciation expense and goodwill
    amortization.

(5) Elimination of legal and investment banking fees incurred by FCR in
    connection with KTI's acquisition of FCR.

(6) Additional goodwill amortization expense. Goodwill is amortized over 30
    years.

(7) Additional interest expense on refinanced and incremental debt outstanding
    assuming an average interest rate of 8.75%.

3. EARNINGS PER SHARE

    The pro forma earnings per share calculations are based on the unaudited
adjusted historical basic and diluted weighted average number of shares
outstanding adjusted for the issuance of shares for the acquisition of FCR.

                      DESCRIPTION OF CASELLA CAPITAL STOCK

AUTHORIZED CAPITAL STOCK

    The authorized capital stock of Casella consists of 100,000,000 shares of
Casella Class A common stock, $0.01 par value per share, 1,000,000 shares of
Casella Class B common stock, $0.01 par value per share, and 1,000,000 shares of
preferred stock, $0.01 par value per share.

COMMON STOCK

    The shares of Casella Class A common stock and Casella Class B common stock
are identical in all respects, except for voting rights, conversion rights and
transfer restrictions. The number of authorized shares of any class or classes
of capital stock of Casella may be increased or decreased, but not below the
number of shares then outstanding, by the affirmative vote of the holders of a
majority of the voting power of common stock entitled to elect directors and
irrespective of the provisions of Section 242(b)(2) of the Delaware General
Corporation Law statute.

    VOTING RIGHTS.  The holders of Casella Class A common stock are entitled to
one vote per share. Holders of Casella Class B common stock are entitled to ten
votes per share. Holders of all classes of common stock entitled to vote will
vote together as a single class on all matters, except that the holders of
Casella Class A common stock will be entitled to elect, without the Casella
Class B common stock voting, at least one director, and that director may be
removed, with or without cause, by the holders of the Casella Class A common
stock. Mr. Gregory B. Peters is the designee of the holders of Casella Class A
common stock.

    DIVIDENDS.  If dividends are declared by the Casella board, holders of
Casella Class A common stock and Casella Class B common stock will receive them
at the same rate, but only after any dividends required to be paid on shares of
preferred stock have been paid. Casella may not make any dividend or
distribution to any holder of any class of common stock unless it simultaneously
makes the same dividend or distribution to each outstanding share of common
stock regardless of class. In the case of a dividend or other distribution
payable in shares of a class of common stock, Casella Class A common stock will
be distributed in respect of holders of Casella Class A common stock and Casella
Class B common stock will be distributed in respect of holders of Casella
Class B common stock and the number of shares of each class of common stock
payable per share of that class of common stock will be equal in number. In the
case of dividends or other distributions consisting of other voting securities
of Casella, Casella will declare and pay dividends in two separate classes of
the voting securities, identical in all respects except that:

    - the security issued to holders of Casella Class B common stock will
      convert into the security issued to the holders of Casella Class A common
      stock upon the same terms and conditions applicable to the conversion of
      Casella Class B common stock into Casella Class A common stock and will
      have the same restrictions on transfer and ownership applicable to the
      transfer and ownership of the Casella Class B common stock;

    - with respect only to dividends or other distributions of voting securities
      of a wholly owned subsidiary of Casella, the voting rights of each
      security issued to holders of Casella Class A common stock and Casella
      Class B common stock with respect to elections of directors will be the
      same as those of the Casella Class A common stock and Casella Class B
      common stock described above; and

    - in the case of dividends or other distributions consisting of securities
      convertible into, or exchangeable for, voting securities of Casella, the
      company will provide that the convertible or exchangeable securities and
      the underlying securities be identical in all respects, including the
      conversion or exchange rate, except that the underlying securities may
      have the same differences

                                      142
<PAGE>
      as they would have if the company issued voting securities of Casella,
      exchangeable for the securities.

    RESTRICTIONS ON ADDITIONAL ISSUANCES AND TRANSFER.  Casella may not issue or
sell any shares of Casella Class B common stock or any securities convertible
into shares of Casella Class B common stock to any person who is not a Casella
Class B permitted holder, as described below. Additionally, shares of Casella
Class B common stock may not be transferred to a person other than a Casella
Class B permitted holder. However, these transfer restrictions shall not apply
in the case of a merger, consolidation or business combination involving Casella
in which the acquiror purchases all of the outstanding shares of common stock
and preferred stock of Casella.

    CONVERSION.  Casella Class A common stock has no conversion rights. Shares
of Casella Class B common stock are convertible into Casella Class A common
stock, in whole or in part, at any time and on more than one occasion, at the
holder's option, on the basis of one share of Casella Class A common stock for
each share of Casella Class B common stock converted. Each share of Casella
Class B common stock will also automatically convert into one share of Casella
Class A common stock if, on the record date for any meeting of the stockholders
of Casella, the number of shares of common stock held by the Class B permitted
holders is less than 1,077,874 shares, subject to appropriate adjustment for
stock splits, reverse stock splits, stock dividends and similar transactions.
Additionally, at the time a person ceases to be a Class B permitted holder, any
share of Casella Class B common stock held by that person will automatically
convert into a share of Casella Class A common stock. Casella has agreed that it
will:

    - reserve and keep available out of its authorized but unissued shares of
      Casella Class A common stock, the number of shares of Casella Class A
      common stock issuable upon the conversion of all outstanding shares of
      Casella Class B common stock;

    - register and obtain the necessary governmental approvals for any shares of
      Casella Class A common stock issuable upon conversion of a share of
      Casella Class B common stock before the shares of Casella Class A common
      stock are issued; and

    - use its best efforts to list the shares of Casella Class A common stock
      issuable upon conversion of Casella Class B common stock on the national
      securities exchange on which outstanding Casella Class A common stock is
      then listed before those issuable shares of Casella Class A common stock
      are delivered.

    RECLASSIFICATION AND MERGER.  In the event of a reclassification or other
similar transaction which results in shares of Casella Class A common stock
being converted into another security, then a holder of Casella Class B common
stock will be entitled to receive upon conversion the amount of the other
security that the holder would have received if the conversion occurred
immediately prior to the record date of the reclassification or other similar
transaction. No adjustments for dividends will be made upon the conversion of
any share of Casella Class B common stock; except if a share is converted
subsequent to the record date for the payment of a dividend or other
distribution on shares of Casella Class B common stock but prior to the payment,
then the registered holder of the share at the close of business on the record
date will receive the dividend or other distribution payable on that date
regardless of the conversion or Casella's default in payment of the dividend due
on the date.

    In the event Casella enters into any consolidation, merger, combination or
other transaction in which shares of common stock are exchanged for or changed
into other stock or securities, cash and/or any other property, then the shares
of each class of common stock will be exchanged for or changed into either:

    - the same amount of stock, securities, cash and/or any other property into
      which each share of any other class of common stock is exchanged or
      changed; provided, however, that if shares of common stock are exchanged
      for or changed into shares of capital stock, the shares so

                                      143
<PAGE>
      exchanged for or changed into may differ only to the extent that the
      Casella Class A common stock and the Casella Class B common stock differ
      as provided in Casella's charter; or

    - if holders of each class of common stock are to receive different
      distributions of stock, securities, cash and/or any other property, an
      amount of stock, securities, cash and/or property per share having a
      value, as determined by an independent investment banking firm of national
      reputation selected by the board of directors, equal to the value per
      share into which or for which each share of any other class of common
      stock is exchanged or changed.

    LIQUIDATION.  In the event of a liquidation of Casella, after the payment of
its debts and other liabilities and after making provision for the holders of
preferred stock, if any, the remaining assets of Casella will be distributable
ratably among the holders of the Casella Class A common stock and Casella
Class B common stock.

    OTHER PROVISIONS.  The holders of the Casella Class A common stock and
Casella Class B common stock are not entitled to preemptive rights. None of the
Casella Class A common stock or Casella Class B common stock may be subdivided
or combined in any manner unless the other classes are subdivided or combined in
the same proportion. Casella may not make any offering of options or other
rights to subscribe for shares of Casella Class B common stock. If Casella makes
an offering of options or other rights to subscribe for shares of any class of
capital stock, other than Casella Class B common stock, to all holders of a
class of common stock, then it is required to simultaneously make an identical
offering to all holders of the other classes of common stock, unless that class
votes to waive that right. All such options or other rights offerings shall
offer the respective holders of Casella Class A common stock and Casella
Class B common stock the right to subscribe at the same rate per share.

    A "Class B permitted holder" includes only the following persons:

    - John W. Casella or Douglas R. Casella and their spouses and each of their
      respective estates, guardians, conservators or committees;

    - each descendant of John W. Casella or Douglas R. Casella and their
      respective estates, guardians, conservators or committees;

    - any (a) not-for-profit corporation if at least a majority of its board of
      directors is composed of John W. Casella or Douglas R. Casella, their
      spouses and/or descendants of John W. Casella or Douglas R. Casella; (b)
      other corporation if at least a majority of the value of its outstanding
      equity is owned by Class B permitted holders; (c) partnership if at least
      a majority of the economic interest of its partnership interests are owned
      by Class B permitted holders; and (d) limited liability or similar company
      if at least a majority of the economic interest of Casella is owned by
      Class B permitted holders; and

    - trustees, in that capacity, of trusts where the primary beneficiaries are
      John W. Casella or Douglas R. Casella, their spouses, the descendants of
      John W. Casella and Douglas R. Casella, and the spouses of these
      descendants and each of their respective estates, guardians, conservator
      or committees and/or charitable organizations, provided that if the trust
      is a wholly charitable trust, at least a majority of the trustees of the
      trust consist of John W. Casella or Douglas R. Casella, their spouses
      and/or Class B permitted holders.

PREFERRED STOCK

    The Casella board is authorized, without stockholder approval, to issue up
to 1,000,000 shares of preferred stock in one or more series. The Casella board
will determine the rights, preferences, privileges and restrictions, including
voting rights, dividend rights, exchange rights, conversion rights, redemption
privileges and liquidation preferences, of each series of preferred stock. The
rights of the holders of shares of common stock are subject to, and may be
adversely affected by, the rights of the holders of any shares of preferred
stock that may be issued. Preferred stock may, at the discretion of

                                      144
<PAGE>
the Casella board, be entitled, before the common stock, to the payment of
dividends and the distribution of assets in the event of the liquidation,
dissolution or winding up of the company. Additionally, the issuance of shares
of preferred stock could also decrease the amount of earnings and assets
available for distribution to the holders of Casella common stock. If any
cumulative dividends or amounts payable on a return of capital are not paid in
full, all shares of preferred stock would participate ratably according to the
amounts that would be payable on these shares if all (a) dividends were declared
and paid in full, or (b) sums which would be payable on these shares on the
return of capital were paid in full.

    The purpose of authorizing the board of directors to issue preferred stock
and determine its rights and preferences is to eliminate delays associated with
a stockholder vote on specific issuances. The issuance of preferred stock, while
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of making it more difficult for
a third party to acquire, or of discouraging a third party from acquiring, a
majority of the outstanding voting capital stock of Casella. Casella has no
present plans to issue any shares of preferred stock.

DELAWARE LAW AND CHARTER AND BY-LAW PROVISIONS

    Casella is subject to the provisions of Section 203 of the Delaware General
Corporation Law. In general, this statute prohibits a publicly-held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person becomes an interested stockholder, unless the business
combination is approved in a prescribed manner. An "interested stockholder" is a
person who, together with affiliates and associates, owns or within the prior
three years did own 15% or more of the corporation's voting stock.

    Casella's charter provides that vacancies on the board of directors may only
be filled by a majority of the board of directors then in office. Furthermore,
any director elected by the stockholders, or by the board of directors to fill a
vacancy, may be removed only by a vote of 75% of the combined voting power of
the shares of common stock entitled to vote for the election of directors,
provided that the director elected by the holders of Class A common stock,
voting separately as a class, may be removed only by the holders of at least 75%
of the outstanding shares of Class A common stock.

    Casella's charter and by-laws provide that any action required or permitted
to be taken by the stockholders of Casella may be taken only at a duly called
annual or special meeting of stockholders. These provisions could have the
effect of delaying until the next stockholders meeting stockholder actions which
are favored by the holders of a majority of the outstanding voting securities of
Casella, especially since special meetings of stockholders may be called only by
the board of directors or president of Casella. These provisions may also
discourage another person or entity from making a tender offer for Casella's
common stock, because that person or entity, even if it acquired a majority of
the outstanding voting securities of Casella, would be able to take action as a
stockholder, including electing new directors or approving a merger, only at a
duly called stockholders meeting, and not by written consent. The by-laws also
establish procedures, including advance notice procedures, with regard to the
nomination, other than by or at the direction of the board of directors, of
candidates for election as directors and other matters to be brought before
stockholders meetings.

    Casella's charter and by-laws also provide for the classification of the
board of directors, whereby no more than one-third of the board is elected in
any one year. The effect of such provision could be to delay the ability of
another person or entity to take control of the board.

    These provisions, which may be amended only by a 75% vote of the
stockholders, could make it more difficult for a third party to effect a change
in the control of the board of directors. In addition, these provisions could
make it more difficult for a third party to acquire, or it could discourage a
third

                                      145
<PAGE>
party from attempting to acquire, a majority of the outstanding voting stock of
Casella and may make more difficult or discourage a takeover of Casella.

    Casella has also included in its charter provisions to eliminate the
personal liability of its directors for monetary damages resulting from breaches
of their fiduciary duty to the extent permitted by Delaware General Corporation
Law and to indemnify its directors and officers to the fullest extent permitted
by Section 145 of the Delaware General Corporation Law.

TRANSFER AGENT AND REGISTRAR

    The transfer agent and registrar for the Casella common stock is Boston
EquiServe, L.P., Canton, Massachusetts.

                                      146
<PAGE>
                        COMPARISON OF STOCKHOLDER RIGHTS

    Casella is incorporated in Delaware and KTI is incorporated in New Jersey.
As a result of the merger, KTI shareholders will receive, in exchange for their
shares of KTI common stock, shares of Casella Class A common stock and will
become stockholders of Casella. The rights of Casella stockholders are governed
by Delaware law and Casella's charter and by-laws.

    The New Jersey Business Corporation Act, which governs the rights of KTI
shareholders, and the Delaware General Corporation Law, which governs the rights
of Casella stockholders, differ in many respects. In addition, Casella's charter
and by-laws differ in several significant respects from KTI's charter and
by-laws. The following summary of significant differences that may affect the
rights and interests of stockholders is not intended to be a complete discussion
of the differences, and is qualified in its entirety by reference to Casella's
charter and by-laws and KTI's charter and by-laws, the relevant statutes under
Delaware and New Jersey law, all of which may change from time to time.

VOTING REQUIREMENTS

    Both the New Jersey and Delaware law provide, except as set forth below,
that whenever any action is to be taken by vote of the stockholders, it shall be
authorized by a majority of the votes cast at a meeting of stockholders by the
holders of shares entitled to vote, unless a greater plurality is required by
the corporation's charter, or another section of the New Jersey or Delaware law
is applicable.

    Under New Jersey law, unless a greater vote is specified in the
corporation's charter, (a) any amendment to a New Jersey corporation's charter,
(b) the voluntary dissolution of the corporation, (c) the sale or other
disposition of all or substantially all of a corporation's assets otherwise than
in the ordinary course of business or (d) the merger or consolidation of the
corporation with another corporation, requires in each case the affirmative vote
of a majority of the votes cast by shareholders of the corporation entitled to
vote thereon.

    The New Jersey Shareholders Protection Act limits certain transactions
involving an "interested stockholder" and a resident domestic corporation. An
"interested stockholder" is a direct or indirect beneficial owner of 10% or more
of the voting power of the outstanding voting stock of a resident domestic
corporation. This New Jersey statute prohibits certain business combinations
between an interested stockholder and a resident domestic corporation for a
period of five years after the date the interested stockholder first becomes an
interested stockholder, unless the business combination was approved by the
resident domestic corporation's board of directors prior to the date the
interested stockholder first becomes an interested stockholder. After the
five-year period expires, the prohibition on these business combinations
continues unless the combination is approved by (a) the affirmative vote of
two-thirds of the voting stock not beneficially owned by the interested
stockholder, (b) by the board prior to the interested stockholder first becoming
an interested stockholder or (c) certain fair price provisions are satisfied.

    The KTI charter contains provisions known as "supermajority" and "fair
price" provisions which are anti-takeover measures and could affect the price
KTI shareholders receive for shares of KTI common stock.

    Under Delaware law, unless otherwise specified in the charter of a Delaware
corporation, (a) an amendment to the charter, (b) the sale or other disposition
of all or substantially all of the assets of a corporation, or (c) the merger or
consolidation of a corporation with another corporation all require the
affirmative vote of a majority of the outstanding stock entitled to vote
thereon, and, with respect to the amendment of the charter, the affirmative vote
of a majority of the outstanding shares of stock of each class entitled to vote
thereon is also required. Provisions of Casella's charter relating to limiting

                                      147
<PAGE>
stockholder action only to duly called annual or special meetings and removal of
directors may only be amended by a 75% vote of Casella stockholders.

    Under Delaware law, subject to certain exceptions, an interested stockholder
of a Delaware corporation may not engage in any business combination with the
corporation for a three-year period following the time that the stockholder
becomes an interested stockholder unless:

    - prior to the time, the board of directors of the corporation approved
      either the business combination or the transaction which resulted in the
      stockholder becoming an interested stockholder;

    - upon consummation of the transaction which resulted in the stockholder
      becoming an interested stockholder, the interested stockholder owned at
      least 85% of the voting stock of the corporation outstanding at the time
      the transaction commenced, excluding certain shares held by officers and
      directors and shares held in employee stock plans; or

    - on or subsequent to the time, the business combination is approved by the
      board of directors of the corporation and authorized at an annual or
      special meeting of stockholders by the affirmative vote of at least
      two-thirds of the outstanding voting stock which is not owned by the
      interested stockholder.

    Except as otherwise specified in the statute, an interested stockholder
includes:

    - any person that is the owner of 15% or more of the outstanding voting
      stock of the corporation, or is an affiliate or associate of the
      corporation and was the owner of 15% or more of the outstanding voting
      stock of the corporation at any time within three years immediately prior
      to the relevant date; and

    - the affiliates and associates of any such person.

    Under certain circumstances, the statute makes it more difficult for a
person who would be an interested stockholder to effect various business
combinations with a corporation for a three-year period, although the
stockholders may elect to exclude a corporation from the restrictions imposed
thereunder. Casella's charter does not exclude it from the restrictions imposed
under the statutes.

STOCKHOLDER POWER TO CALL SPECIAL STOCKHOLDERS MEETING

    Under New Jersey law, special meetings of the shareholders may be called by
the president or the board of directors, or by other officers, directors or
shareholders as may be provided in the by-laws. In addition, upon the
application of the holders of not less than 10% of all shares entitled to vote
at the meeting, the Superior Court, for good cause shown, may order a special
meeting of the shareholders. KTI's by-laws provide that special shareholders
meetings can be called by a majority of the KTI board, the president, the
chairman of the board, or the secretary if the holders of at least 25% of the
shares entitled to vote at the meeting request the meeting in writing, stating
the purpose and the matters proposed to be acted on.

    Under Delaware law, special meetings of the stockholders may be called by
the board of directors or by persons as may be authorized by the corporation's
charter or by-laws. The Casella by-laws provide that special meetings of
stockholders can be called by the chairman of the Casella board or the
president.

DISSOLUTION

    Under New Jersey law, a corporation may be dissolved by the consent of all
its shareholders entitled to vote thereon. New Jersey law further provides that
a corporation may also be dissolved by action of its board of directors and its
shareholders if the board of directors recommends that the

                                      148
<PAGE>
corporation be dissolved, directs that the question of dissolution be submitted
to a vote at a meeting of shareholders and the dissolution is approved by the
affirmative vote of a majority of the votes cast by holders of the outstanding
shares of common stock present in person or represented by proxy and entitled to
vote at the meeting. The charter may provide for greater requirements. The KTI
charter requires the affirmative vote of two-thirds of the votes.

    Under Delaware law, the board of directors may, by a majority of the whole
board at any meeting called for that purpose, cause notice of dissolution to be
mailed to each stockholder entitled to vote thereon, and the majority of the
outstanding stock of the corporation entitled to vote must vote for the proposed
dissolution. Dissolution may also be authorized without action of the directors
if all of the stockholders entitled to vote thereon consent in writing and a
certificate of dissolution is filed with the Secretary of State.

CUMULATIVE VOTING

    Under New Jersey law, shareholders of a New Jersey corporation do not have
cumulative voting rights in the election of directors unless the certificate of
incorporation so provides. The KTI charter does not presently provide for
cumulative voting.

    Under Delaware law, stockholders of a Delaware corporation do not have
cumulative voting rights in the election of directors unless the certificate of
incorporation so provides. The Casella charter does not presently provide for
cumulative voting.

CLASSIFIED BOARD OF DIRECTORS

    New Jersey law permits a New Jersey corporation to provide for a classified
board in its charter. The KTI board is not divided into classes. New Jersey law
also permits the removal of directors with cause or, unless otherwise provided
in the charter, without cause. KTI's charter does not provide otherwise.

    Delaware law permits a Delaware corporation to provide for a classified
board in its charter or by-laws. The Casella charter provides that the Casella
board is divided into three classes, each of which contains approximately
one-third of the whole number of members of the Casella board. Each class serves
a staggered term, with approximately one-third of the total number of directors
being elected each year. Under Delaware law, directors on a classified board may
only be removed for cause, unless the charter of the company provides otherwise.
Casella's charter provides for the removal of directors with and without cause
by the holders of 75% of the votes entitled to be cast for the election of such
directors.

RIGHTS OF DISSENTING STOCKHOLDERS

    Shareholders of a New Jersey corporation who dissent from a merger,
consolidation, sale of all or substantially all of the corporation's assets or
certain other corporate transactions are generally entitled to appraisal rights.
No statutory right of appraisal exists, however, where the stock of the New
Jersey corporation is:

    - listed on a national securities exchange;

    - is held of record by not less than 1,000 holders; or

    - where the consideration to be received pursuant to the merger,
      consolidation or sale consists of cash or securities or other obligations
      which, after the transaction, will be listed on a national securities
      exchange or held of record by not less than 1,000 holders.

    Stockholders of a Delaware corporation who dissent from a merger or
consolidation of the corporation may be entitled to appraisal rights. There are
no statutory rights of appraisal with respect to stockholders of a corporation
whose shares are 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 stockholders, where stockholders receive
      only shares of stock or depository receipts of the corporation surviving
      or resulting from the merger or consolidation or shares of stock or
      depository receipts of any other corporation which 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 stockholders (or cash
      in lieu of fractional share interests therein).

STOCKHOLDER CONSENT TO CORPORATE ACTION

    New Jersey law permits any action required or permitted to be taken at a
meeting of shareholders to be taken without a meeting if all of the shareholders
who are entitled to vote on the action consent to the action in writing, except
if the action is to approve a merger or consolidation of the corporation or the
sale of substantially all of the corporation's assets the action may be taken
without a meeting only if (a) all the corporation's shareholders consent to the
action in writing or (b) all of the corporation's shareholders who are entitled
to vote on the action consent to the action in writing and the corporation
provides to all other shareholders notice of the action in advance of the
proposed effective date of the action. If the charter of a New Jersey
corporation does not provide otherwise and certain notice and other requirements
are complied with, New Jersey law also permits any action required or permitted
to be taken at a meeting of the shareholders, other than the annual election of
directors, to be taken without a meeting, without prior notice and without a
vote, upon the written consent of the minimum number of votes which would be
necessary to authorize the action at a meeting at which all shareholders
entitled to vote on the action were present and voting. Since KTI's charter does
not prohibit shareholder action by less than unanimous consent, such action may
be taken by KTI's shareholders.

    Unless otherwise provided in the charter, Delaware law permits stockholders
to act by written consent if consents setting forth the action being taken are
signed by the holders of the outstanding stock having not less than the minimum
number of votes that would be necessary to authorize or take the action at a
meeting at which all shares entitled to vote thereon were present and voted.
Directors may be elected by written consent in lieu of an annual meeting only if
unanimous or, if such consent is less than unanimous, if all of the
directorships to which directors could be elected at an annual meeting are
vacant and are filled by the written action. The Casella by-laws provide that
vacancies and newly created directorships shall be filled by a majority of
directors then in office although less than a quorum. The Casella charter does
not permit stockholders to act by written consent.

ADVANCE NOTICE BY-LAWS

    Both New Jersey law and Delaware law as well as both KTI's by-laws and
Casella's by-laws provide that their stockholders must receive written notice of
meetings not less than 10 and not more than 60 days before a meeting of
stockholders is held. Casella's by-laws provide for advance notice procedures
with regard to the nomination, other than by or at the direction of the Casella
board, of candidates for election of directors and other matters to be brought
before the stockholder's meeting.

DIVIDENDS

    Unless there are other restrictions contained in a corporation's charter,
New Jersey law generally provides that a New Jersey corporation may declare and
pay dividends on its outstanding stock so long as the corporation can pay its
debts as they become due in the usual course of its business or its total assets
are more than its total liabilities. KTI's charter does not contain this
restriction.

    Delaware law generally limits dividends payable by Casella to an amount
equal to the excess of the net assets of the company over its statutory capital,
or if there is no excess, to its net profits for the current and/or immediately
preceding fiscal year.

BY-LAWS

    Under New Jersey law, the board of directors of a New Jersey corporation has
the power to adopt, amend, or repeal the corporation's by-laws, unless the
powers are reserved in the charter to the shareholders. KTI's charter does not
presently reserve such powers for its stockholders.

    Under Delaware law, the stockholders of a Delaware corporation have the
power to adopt, amend, or repeal the corporation's by-laws, unless such powers
also are reserved in the charter to the board of directors. Casella's by-laws
may be amended by the board of directors.

LIMITATIONS OF LIABILITY OF DIRECTORS AND OFFICERS

    Under New Jersey law, a New Jersey corporation may include in its charter a
provision which would, subject to the limitations described below, eliminate or
limit directors' or officers' liability to the corporation or to its
shareholders, for damages for breaches of any duty owed to the corporation or
its shareholders. A director or officer cannot be relieved from liability for
any breach of duty based upon an act or omission (a) in breach of such person's
duty of loyalty to the corporation or its shareholders, (b) not in good faith or
involving a knowing violation of law, or (c) resulting in receipt by such person
of an improper personal benefit. KTI's charter contains provisions which limit a
director's or officer's liability to the full extent permitted by New Jersey
law.

    Under Delaware law, a Delaware corporation may include in its charter a
provision which would, subject to the limitations described below, eliminate or
limit directors' liability to the corporation or its stockholders, for monetary
damage for breaches of their fiduciary duty of care. A director cannot be
relieved from liability or otherwise indemnified (a) for breach of the
director's duty of loyalty, (b) for acts or omissions not in good faith or
involving intentional misconduct or knowing violation of law, (c) for willful or
negligent conduct in paying dividends or repurchasing stock out of other than
lawfully available funds, or (d) for any transaction from which the director
derives an improper personal benefit. Casella's charter contains provisions
which limit a director's liability to the full extent permitted by Delaware law.

CONSIDERATION OF ACQUISITION PROPOSALS

    New Jersey law provides that in determining whether a proposal or offer to
acquire a corporation is in the best interest of the corporation, the board may,
in addition to considering the effects of any action on shareholders, consider
any of the following:

    - the effects of the proposed action on the corporation's employees,
      suppliers, creditors and customers;

    - the effects of the proposed action on the community in which the
      corporation operates; and

                                      151
<PAGE>
    - the long-term as well as the short-term interests of the corporation and
      its shareholders, including the possibility that those interests may be
      served best by the continued independence of the corporation.

    The statute further provides that if, based on those factors, the board
determines that any such offer is not in the best interest of the corporation,
it may reject the offer. If the board determines to reject an offer, the statute
provides that the board will have no obligation to facilitate, remove any
barriers to or refrain from impeding the offer. These provisions may make it
more difficult for a shareholder to challenge a New Jersey corporation's board's
rejection of, and may facilitate the board's rejection of, an offer to acquire
the corporation.

    There are no comparable provisions under Delaware law. Casella's charter
permits the board of directors to take into account the interests of creditors,
customers, employees and other constituencies in considering corporate actions.

                         ELECTION OF CASELLA DIRECTORS

GENERAL

    Casella has three classes of directors consisting of one Class I director,
two Class II directors and two Class III directors. At each annual meeting,
directors are elected for a full term of three years to succeed those whose
terms are expiring. The terms of the three classes are staggered in a manner so
that only one class is elected by stockholders annually. The two Class II
directors are proposed for election this year to serve as members of the Casella
board until the 2002 annual meeting of stockholders, or until their successors
are elected and qualified. After the merger, the Casella board will be increased
to 11 members, consisting of four Class I directors, four Class II directors and
three Class III directors. See "The Merger--Directors and executive officers of
the combined company following the merger".

    The persons named in the enclosed proxy will vote at the Casella annual
meeting to elect, as Class II directors, Messrs. James W. Bohlig and Gregory P.
Peters, the two director nominees named below, unless the proxy is marked
otherwise. Messrs. Bohlig and Peters are currently members of the Casella board.
Mr. Peters has been nominated as the designee of the holders of Casella Class A
common stock.

    Each of the nominees has indicated his willingness to serve, if elected;
however, if any nominee should be unable to serve, the person acting under the
proxy may vote the proxy for a substitute nominee designated by the Casella
board. The Casella board has no reason to believe that any of the nominees will
be unable to serve if elected.

    Set forth below for each Casella director, including the director nominees,
is information as of September 1, 1999 with respect to (a) his name and age,
(b) position and offices at Casella, (c) principal occupation and business
experience during the past five years, (d) directorships, if any, of other
publicly held companies and (e) the year he became a director of Casella.

    See "The Companies--Casella--Certain relationships and related transactions"
and "--Stock ownership of management" for information concerning Casella
directors, including those who are nominees for election as Class II directors.

    The holders of Casella Class A common stock, voting separately as a class,
will at all times be entitled to elect at least one director. Mr. Peters, a
Class II director nominee, has been nominated to be the designee of the holders
of Casella Class A common stock as a result of the resignation of
Michael Cronin, formerly the designee of the holders of Casella Class A common
stock.

    Messrs. Bohlig, John W. Casella, Douglas R. Casella, Chapple and Peters were
elected to the Casella board pursuant to the terms of an agreement by and
between Casella and certain stockholders. The agreement terminated upon
completion of Casella's initial public offering of its common stock in
November 1997.

BOARD OF DIRECTORS AND COMMITTEE MEETINGS

    The Casella board met ten times, including by telephone conference, during
fiscal 1999. All directors attended at least 75% of the meetings of the Casella
board and the meetings of the committees on which they served, except that
Mr. Chapple did not attend the meeting of the audit committee.

    The Casella board has established a compensation committee. The compensation
committee, which currently consists of Messrs. John W. Casella, Chapple and
Peters, reviews executive salaries, administers any bonus, incentive
compensation and stock option plans of Casella, and approves the salaries and
other benefits of the executive officers of Casella. In addition, the
compensation committee consults with Casella management regarding pension and
other benefit plans and compensation policies and practices of Casella. The
stock plan subcommittee of the compensation committee, which currently consists
of Messrs. Chapple and Peters, administers the issuance of stock options and
other awards under Casella's stock option plans to Casella's executive officers
and approves the compensation of Mr. John W. Casella. The compensation committee
and the stock plan subcommittee each held one meeting during fiscal 1999.

    The Casella board has also established an audit committee. The audit
committee, which currently consists of Messrs. Chapple and Peters, reviews the
professional services provided by Casella's independent auditors, the
independence of the auditors from management of Casella and Casella's annual
financial statements and system of internal accounting controls. The audit
committee also reviews such other matters with respect to the accounting,
auditing and financial reporting practices and procedures of Casella as it may
find appropriate or as may be brought to its attention. The audit committee held
one meeting during fiscal 1999.

    Casella does not have a nominating committee or a committee serving a
similar function. Nominations are made by and through the full Casella board.

COMPENSATION OF DIRECTORS

    Casella reimburses non-employee directors for expenses incurred in attending
Casella board meetings. Non-employee directors of Casella receive stock options
under Casella's 1997 Non-Employee Director Stock Option Plan. The Non-Employee
Director Plan currently provides that each non-employee director will receive an
automatic grant of a nonqualified stock option to purchase 5,000 shares of
Casella Class A common stock upon his or her initial election to the Casella
board, vesting in three equal installments beginning on the first anniversary of
the date of grant. In addition, an option to purchase 2,000 shares of Casella
Class A common stock is granted to each incumbent non-employee director on the
date of each annual meeting of stockholders, vesting in three equal annual
installments beginning on the first anniversary of the date of grant. Options
granted under the Non-Employee

                                      155
<PAGE>
Director Plan expire ten years from the date of grant. The exercise price of
options granted under the Non-Employee Director Plan is equal to the fair market
value of a share of Casella Class A common stock as of the date of grant.
Casella has reserved a total of 50,000 shares of Casella Class A common stock
for issuance under the Non-Employee Director Plan, 46,000 of which were
available for grant as of July 30, 1999.

    The Casella board has recommended increasing the number of shares of Casella
Class A common stock available for grant under the Non-Employee Director Plan
from 50,000 to 100,000 and to increase the number of shares subject to the stock
options granted to non-employee directors upon initial election to the Casella
board and on the date of each annual meeting from 5,000 and 2,000, respectively,
to 7,500 on the date of each such event. See "Approval of Amendments to the
Casella 1997 Non-Employee Director Stock Option Plan."

    Casella has also entered into or engaged in certain transactions with
directors of Casella or affiliates of directors of Casella. See "The
Companies--Casella--Certain relationships and related transactions".

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    The current members of the compensation committee of the Casella board are
Messrs. John W. Casella, Chapple and Peters. The current members of the stock
plan subcommittee of the Casella board are Messrs. Chapple and Peters.
Mr. Casella has served as president and chief executive officer of Casella since
1993.

    Casella has from time to time engaged Casella Construction, Inc., a company
owned by John W. Casella and Douglas R. Casella, a director, to provide
construction services for the company, including construction, closure and
capping activities at the company's landfills. In fiscal 1999, the company paid
Casella Construction, Inc. an aggregate of $5,198,000.

    Casella is party to two real estate leases with Casella Associates, a
Vermont partnership owned by John W. Casella and Douglas R. Casella, relating to
facilities occupied by the company. The leases, relating to the company's
corporate headquarters in Rutland, Vermont and its Montpelier, Vermont facility,
call for aggregate monthly payments of approximately $18,000 and expire in
April 2003. These leases have been classified by the company as capital leases
for financial reporting purposes. In addition, the company leases furniture and
fixtures from Casella Associates pursuant to an operating lease which bore rent
at $950 per month and which expired in May 1999. In fiscal 1999, the company
paid Casella Associates an aggregate of $237,101 for such leases. In
November 1997, the lease relating to the company's corporate headquarters in
Rutland, Vermont was amended to allow the company to upgrade and make capital
improvements to the premises at an estimated cost of $500,000, to be paid by the
company. Casella Associates was granted the option to purchase the capital
improvements by December 31, 2002, and if it does not elect to exercise the
option the company has the right to purchase the premises for $324,000, the fair
market value of the premises prior to the capital improvements, at the
expiration of the term of the lease.

    Casella operated an unlined landfill located in Whitehall, New York owned by
Bola, Inc., a corporation owned by John W. Casella and Douglas R. Casella which
operated as a single-purpose real estate holding company. The company paid the
cost of closing this landfill in 1992, and has agreed to pay all post-closure
obligations. In fiscal 1999, the company paid an aggregate of $3,161 pursuant to
this arrangement.

    In connection with and at the time of Casella's acquisition of the business
of Catamount Waste Services, Inc., Casella entered into a lease in June 1994
with CV Landfill, Inc., a Vermont corporation affiliated with Catamount Waste
Services, Inc., pursuant to which Casella agreed to lease a transfer station for
a term of 10 years. CV Landfill, Inc. is owned by John F. Chapple III, who
became a

                                      156
<PAGE>
director of Casella at the time of the acquisition of the business of Catamount
Waste Services, Inc. Pursuant to the lease agreement, Casella pays monthly rent
for the first five years at a rate of $5.00 per ton of waste disposed of at the
transfer station, with a minimum rent of $6,650 per month. Following the fifth
anniversary of the lease agreement, Casella is required to pay monthly rent at a
rate of $2.00 per ton, with a minimum rent of $2,500 per month. In fiscal 1999,
Casella paid CV Landfill, Inc. an aggregate of $116,116.

    Casella believes that each transaction described above was on terms at least
as favorable as those Casella would expect to negotiate with disinterested third
parties. In addition, in connection with the proposed merger with KTI, certain
executive officers and directors of Casella have interests in the merger that
are in addition to their interests as stockholders of Casella generally. See
"The Merger--Interests of executive officers and directors of Casella and KTI in
the merger". Furthermore, certain executive officers and directors of KTI have
entered into or engaged in certain transaction with KTI. See "The
Companies--KTI--Certain relationships and related transactions".

                      APPROVAL OF AMENDMENT TO THE CASELLA
                 AMENDED AND RESTATED 1997 STOCK INCENTIVE PLAN

    The Casella board believes stock options and stock-based incentives play an
important role in attracting and retaining the services of outstanding personnel
and in encouraging such employees to have a greater personal financial
investment in Casella.

    Casella stockholders approved the Casella 1997 Stock Incentive Plan in
July 1997 at a special meeting. In October 1998, Casella stockholders approved
an amendment to the Incentive Plan to increase the shares available for issuance
under the plan from 2,308,500 to 3,328,135, including up to 1,019,635 shares
subject to outstanding options under Casella's three terminated stock option
plans which are not issued under those terminated plans because the options
expire or are terminated or cancelled. A copy of the Amended and Restated 1997
Stock Incentive Plan is attached to this proxy statement/prospectus as Annex
D-1, which you should be sure to read.

    The Incentive Plan permits Casella to grant incentive stock options,
non-qualified options, restricted stock awards and other stock-based awards,
including the grant of shares based on certain conditions, the grant of
securities convertible into Casella Class A common stock and the grant of stock
appreciation rights. Stock options may not be granted at an exercise price which
is less than 100% of the fair market value of Casella Class A common stock on
the date of grant and may not be granted for a term in excess of ten years.
Subject to adjustment in the event of a stock split or other similar events,
grants may currently be made under the Incentive Plan for up to 3,328,135 shares
of Casella Class A common stock, including up to 1,019,635 shares of Casella
Class A common stock which are currently subject to outstanding options under
terminated option plans, which are not issued under those plans because the
options expire or are terminated or cancelled. Grants may be made to officers,
employees, directors, consultants and advisors of Casella who are responsible
for or contribute to the management, growth, success and profitability of
Casella and who are designated by the committee that administers the Incentive
Plan.

    The Incentive Plan is administered by the compensation committee, provided
that the stock plan subcommittee administers the issuance of awards to Casella's
executive officers. The stock plan subcommittee currently consists of two
outside directors. The compensation committee has the authority to adopt, amend
and repeal the administrative rules, guidelines and practices relating to the
Incentive Plan and to interpret the provisions of the Incentive Plan. The
compensation committee selects the recipients of grants and determines:

    - the number of shares of Casella Class A common stock covered by options
      and the dates upon which the options become exercisable;

    - the exercise price of options;

    - the duration of options; and

    - the number of shares of Casella Class A common stock subject to any
      restricted stock or other stock-based awards and the terms and conditions
      of the awards, including conditions for repurchase, issue price and
      repurchase price.

    The Casella board is required to make appropriate adjustments in connection
with the Incentive Plan and any outstanding awards to reflect stock dividends,
stock splits and certain other events. In the event of a merger, liquidation or
other acquisition event, outstanding awards will be assumed unless the acquiring
or succeeding corporation does not agree to assume the options, in which case
the Casella board will accelerate the awards to make them fully exercisable
prior to consummation of the acquisition event or provide for a cash-out of the
value of any outstanding options. If any award expires or is terminated,
surrendered, cancelled or forfeited, the unused shares of Casella Class A common
stock subject to the award will again be available for grant under the Incentive
Plan.

                                      158
<PAGE>
    As of September 1, 1999, options to purchase a total of 1,085,960 shares of
Casella Class A common stock were outstanding under the Incentive Plan, no
restricted stock awards had been made under the plan and 2,243,175 shares
remained available for future awards. As of September 1, 1999, Casella had 1,504
full-time employees, all of whom were eligible to participate in the plan.
Through September 1, 1999, under the Incentive Plan, John W. Casella, the chief
executive officer, had received 90,000 options, James W. Bohlig, the chief
operating officer, had received 150,000 options and Jerry S. Cifor, the chief
financial officer, had received 110,000 options. As a group, these executive
officers had received an aggregate of 350,000 options through September 1, 1999.
As of such date, all current officers had received an aggregate of 440,000
options under the Incentive Plan. As a group, all employees, excluding the named
executive officers, had received an aggregate of 673,000 options through
September 1, 1999. On September 15, 1999, Casella granted an aggregate of
938,000 options to certain employees, including 75,000 options to each of
John W. Casella and Douglas R. Casella, 150,000 options to James W. Bohlig and
125,000 options to Jerry S. Cifor.

    After considering the increase in the number of employees as a result of the
merger, the Casella board has amended the Incentive Plan to increase the number
of shares of Casella Class A common stock authorized for the granting of awards
under the plan from an aggregate of 3,328,135, including up to 1,019,635 shares
subject to outstanding options under terminated stock option plans, which are
not issued under those terminated plans because the options expire or are
terminated or cancelled, to 5,328,135 and has directed that the amendment be
submitted for approval by a vote of Casella stockholders. As of October 1, 1999,
Casella had approximately 16,011,305 shares outstanding and, if the merger is
approved, will have approximately 23,163,462 shares outstanding. The Casella
board believes stockholder approval of the amendment to the Incentive Plan is
necessary to assure that an adequate number of shares of Casella Class A common
stock will be available for future award in order to provide appropriate
incentives to employees of Casella, including KTI employees upon consummation of
the merger.

    In accordance with the requirements of the regulations under Section 162(m)
of the Internal Revenue Code, the Incentive Plan limits the number of shares
that may be granted to an individual participant in any fiscal year to 200,000
shares.

    The number of individuals receiving stock options or restricted stock awards
varies from year to year depending on various factors, such as the number of
promotions and the company's hiring needs during the year, and thus Casella
cannot now determine future option or award recipients or the amounts to be
allocated to these individuals.

SOME FEDERAL INCOME TAX CONSEQUENCES OF OPTIONS

    NONQUALIFIED STOCK OPTIONS.  The grant of a nonqualified stock option will
not result in the recognition of taxable income by the participant or in a
deduction to Casella. Upon exercise, a participant will recognize ordinary
income in an amount equal to the excess of the fair market value of the stock
purchased over the exercise price. Casella is required to withhold tax on the
amount of income so recognized, and a tax deduction is allowable equal to the
amount of such income, subject to the satisfaction of certain conditions under
Section 162(m) of the Internal Revenue Code in the case of options exercised by
certain of the highest paid officers. Gain or loss upon a subsequent sale of any
stock received upon the exercise of a nonqualified stock option generally would
be taxed as long-term or short-term capital gain or loss, depending upon the
holding period of the stock sold. Certain additional rules apply if the exercise
price for an option is paid in shares previously owned by the participant.

    INCENTIVE STOCK OPTIONS.  Upon the grant or exercise of an incentive stock
option within the meaning of Section 422 of the Internal Revenue Code, no income
will be realized by the participant for federal income tax purposes and Casella
will not be entitled to any deduction. However, the excess of

                                      159
<PAGE>
the fair market value of the stock as of the date of exercise over the exercise
price will constitute an adjustment to taxable income for purposes of the
alternative minimum tax. If the shares of stock underlying an incentive stock
option are not disposed of within the one-year period beginning on the date of
the transfer of the shares to the participant, nor within the two-year period
beginning on the date of grant of the option, any profit realized by the
participant upon the disposition of the shares will be taxed as long-term
capital gain and no deduction will be allowed to Casella. If the shares are
disposed of within the one-year period from the date of transfer of the shares
to the participant, or within the two-year period from the date of grant of the
option, the excess of the fair market value of the shares upon the date of
exercise or, if less, the fair market value on the date of disposition, and a
corresponding deduction will be allowed to Casella. Certain additional rules
apply if the exercise price for an option is paid in shares previously owned by
the participant. If an option that is intended to qualify as an incentive stock
option is exercised by a person who was not continually employed by Casella or
certain of its affiliates from the date of grant of the option to a date not
more than three months prior to such exercise, or one year if such person is
disabled, then the option will not qualify as an incentive stock option plan and
will instead be taxed as a nonqualified stock option, as described above.

    This summary is not a definitive statement of the federal income tax effects
of options under the Incentive Plan, and you should consult with your own tax
advisor to determine the particular tax effects to you of the provisions
discussed here.

    RECOMMENDATION OF THE CASELLA BOARD.  The Casella board recommends that
Casella stockholders vote "FOR" approval of the amendment to the Incentive Plan
to increase the number of shares of Casella Class A common stock that may be
issued under the Incentive Plan from 3,328,135 to 5,328,135.

    VOTE REQUIRED FOR APPROVAL.  The affirmative vote of the holders of shares
representing a majority of the votes cast by the holders of the Casella common
stock entitled to vote at the Casella annual meeting is required for approval of
the amendment to the Incentive Plan.

                         APPROVAL OF AMENDMENTS TO THE
              CASELLA 1997 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

    The Casella stockholders initially approved the Casella 1997 Non-Employee
Director Stock Option Plan in July 1997 at a special meeting. A copy of the 1997
Non-Employee Director Stock Option Plan is attached to this proxy
statement/prospectus as Annex D-2, which you should be sure to read.

    The Non-Employee Director Plan currently provides that each non-employee
director will receive an automatic grant of a nonqualified stock option to
purchase 5,000 shares of Casella Class A common stock upon his or her initial
election to the board, vesting in three equal installments beginning on the
first anniversary of the date of grant. An option to purchase 2,000 shares of
Class A common stock is granted to each incumbent non-employee director on the
date of each annual meeting of stockholders, vesting in three equal annual
installments beginning on the first anniversary of the date of grant. The
exercise price of options granted under the Non-Employee Director Plan is equal
to the fair market value of a share of Casella Class A common stock as of the
date of grant.

    After considering the increase in the number of non-employee directors as a
result of the merger, the Casella board has amended the Non-Employee Director
Plan to increase the number of shares of Casella Class A common stock authorized
for granting of awards under the Non-Employee Director Plan from 50,000 to
100,000 and to increase the number of shares subject to the stock options
granted to non-employee directors upon initial election to the Casella board and
on the date of each annual meeting of stockholders from 5,000 and 2,000,
respectively, to 7,500 on the date of each such event. The Casella board has
directed that the amendments be submitted for approval by a vote of Casella
stockholders. As of October 1, 1999, Casella had 16,011,305 shares outstanding
and, if the merger is approved, will have approximately 23,163,462 shares
outstanding. As of September 1, 1999, options to acquire approximately 4,000
shares of Casella Class A common stock had been granted under the Non-Employee
Director Plan. Following consummation of the merger, grants will no longer be
made under the KTI plan. The Casella board believes stockholder approval of the
amendments to the Non-Employee Director Plan is necessary to assure that an
adequate number of shares of Casella Class A common stock will be available for
future award in order to provide appropriate incentives to non-employee
directors of Casella, including KTI directors who become Casella directors after
consummation of the merger.

    All options granted under the Non-Employee Director Plan are nonqualified
options not entitled to special tax treatment under Section 422 of the Internal
Revenue Code. For a discussion of certain tax consequences of options, see
"Approval of Amendment to the Casella Amended and Restated 1997 Stock Incentive
Plan--Certain Federal Income Tax Consequences of Options" above.

    RECOMMENDATION OF THE CASELLA BOARD.  The Casella board recommends that
Casella stockholders vote "FOR" approval of the amendments to the Casella 1997
Non-Employee Director Plan to increase the number of shares of Casella Class A
common stock that may be issued under the Casella 1997 Director Plan from 50,000
to 100,000 and to increase the number of shares subject to the stock options
granted to non-employee directors upon initial election to the board and on the
date of each annual meeting from 5,000 and 2,000, respectively, to 7,500 on the
date of each such event.

    VOTE REQUIRED FOR APPROVAL.  The affirmative vote of the holders of shares
representing a majority of the votes cast by the holders of the Casella common
stock entitled to vote at the Casella annual meeting is required for approval of
the amendments to the Casella 1997 Non-Employee Director Plan.

                          APPROVAL OF AMENDMENT TO THE
         CASELLA AMENDED AND RESTATED 1997 EMPLOYEE STOCK PURCHASE PLAN

    The Casella stockholders initially approved the Casella Amended and Restated
1997 Employee Stock Purchase Plan in July 1997 at a special meeting. A copy of
the Amended and Restated 1997 Employee Stock Purchase Plan is attached to this
proxy statement/prospectus as Annex D-3, which you should be sure to read. The
Employee Stock Purchase Plan provides eligible participating employees with an
opportunity to purchase shares of Casella Class A common stock at below fair
market value. A maximum of 300,000 shares of Casella Class A common stock were
authorized for issuance under the Employee Stock Purchase Plan.

    The Employee Stock Purchase Plan is administered by the compensation
committee of the Casella board. All employees of Casella, except employees who
own five percent or more of Casella common stock, whose customary employment is
more than 20 hours per week and who have been employed by Casella for at least
six months, are eligible to participate in the Employee Stock Purchase Plan. To
participate in the Employee Stock Purchase Plan, an employee must authorize
Casella to deduct an amount, up to ten percent of the employee's regular pay,
from his or her pay during six-month periods commencing on January 1 and July 1,
or the first business day thereafter, of each year. The maximum number of shares
of Casella Class A common stock that an employee may purchase in any payment
period is determined by applying the formula stated in the Employee Stock
Purchase Plan. The exercise price for the option for each payment period is 85%
of the lesser of the average market price of Casella Class A common stock on the
first or last business day of the payment period. If an employee is not a
participant on the last day of the payment period, the employee is not entitled
to exercise his or her option, and the amount of his or her accumulated payroll
deductions will be refunded. An employee's rights under the Employee Stock
Purchase Plan terminate upon his or her voluntary withdrawal from the plan or
upon termination of employment.

    After considering the increase in the number of employees as a result of the
merger, the Casella board has amended the Employee Stock Purchase Plan to
increase the number of shares of Casella Class A common stock authorized for
issuance under the Employee Stock Purchase Plan from 300,000 to 600,000 shares,
and has directed that the amendment be submitted for approval by a vote of
Casella stockholders. Prior to the amendment and as of October 1, 1999, 9,949
shares had been granted under the Employee Stock Purchase Plan and 290,051
shares remained available for future grant. The Casella board believes
stockholder approval of this amendment is necessary to assure that an adequate
number of shares of Casella Class A common stock will be available for future
grants in order to provide appropriate incentives to employees of Casella,
including KTI employees upon consummation of the merger.

    RECOMMENDATION OF THE CASELLA BOARD.  The Casella board recommends that the
Casella stockholders vote "FOR" approval of the amendment to the Casella Amended
and Restated 1997 Employee Stock Purchase Plan to increase the number of shares
of Casella Class A common stock that may be issued under the Employee Stock
Purchase Plan from 300,000 to 600,000.

    VOTE REQUIRED FOR APPROVAL.  The affirmative vote of the holders of shares
representing a majority of the votes cast by the holders of the Casella common
stock entitled to vote at the Casella annual meeting is required for approval of
the amendment to the Casella Amended and Restated 1997 Employee Stock Purchase
Plan.

                         RATIFICATION OF THE SELECTION
                       OF CASELLA'S INDEPENDENT AUDITORS

    The Casella board has selected Arthur Andersen LLP as independent auditors
of Casella for the current fiscal year ending April 30, 2000, subject to
ratification by stockholders at the annual meeting. If the stockholders do not
ratify the selection of Arthur Andersen LLP, the Casella board will reconsider
the matter. A representative of Arthur Andersen LLP, which served as auditors
for fiscal 1999, is expected to be present at the annual meeting, to respond to
appropriate questions, and to make a statement if he or she so desires.

                             STOCKHOLDER PROPOSALS

    The Casella board will consider proposals of stockholders intended to be
presented for action at Casella's 2000 annual meeting of stockholders. A
stockholder proposal must have been submitted in writing and received at
Casella's principal executive offices, 25 Greens Hill Lane, Rutland, Vermont,
05701, Attention: Secretary, by July 20, 2000, to be considered for inclusion in
Casella's proxy statement relating to the 2000 annual meeting of stockholders.

    In connection with Casella's 2000 annual meeting of stockholders, the
persons appointed by the Casella board will, if Casella does not receive notice
of a matter or proposal to be considered by October 5, 2000, be allowed to use
their discretionary voting authority with respect to any such action or proposal
that is raised at such annual meeting.

    If the merger is not consummated, KTI will hold a 1999 annual meeting of
stockholders. If the KTI annual meeting is held, shareholder proposals intended
to be presented at the KTI annual meeting must be received by KTI prior to a
date to be announced by KTI in advance of the meeting, if they are to be
included in KTI's proxy materials for the annual meeting.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors
KTI, Inc.

We have audited the accompanying consolidated balance sheets of KTI, Inc. as of
December 31, 1998 and 1997, and the related consolidated statements of
operations, stockholders' equity and cash flows for each of the three years in
the period ended December 31, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of KTI, Inc. at
December 31, 1998 and 1997, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended December 31, 1998
in conformity with generally accepted accounting principles.

As discussed in Note 2, the previously issued financial statements for each of
the three years in the period ended December 31, 1998 have been restated to
reflect the deferral of revenue related to certain proceeds received in
connection with the restructuring of a power purchase agreement and the sale of
electric generating capacity with two utilities.

         (IN THOUSANDS OF DOLLARS, EXCEPT SHARE AND PER SHARE AMOUNTS)

1. ORGANIZATION

    KTI, Inc. ("KTI") and subsidiaries (collectively, the "Company"), is an
integrated waste handling business providing wood, paper, corrugated, metals,
plastic and glass processing and recycling, municipal solid waste processing and
disposal capabilities, specialty waste disposal services, recycling of ash
combustion residue, the generation of electricity and steam and the manufacture
of finished products utilizing recyclable materials. The Company also markets
recyclable metals, plastic, paper and corrugated processed at its facilities and
by third parties. The Company operates 53 facilities in 21 states and Canada in
four operating segments: Waste-to-Energy Processing, Finished Products,
Commercial Recycling and Residential Recycling.

    There are significant restrictions on the ability of certain of the
Company's subsidiaries to distribute assets to the Company. These restrictions
result from the terms of certain indebtedness and provisions of other agreements
with third parties. These subsidiaries include the Company's majority-owned
consolidated subsidiaries, Maine Energy Recovery Company ("Maine Energy") and
Penobscot Energy Recovery Company ("PERC") and the Company's wholly-owned
subsidiary Timber Energy Resources, Inc. ("TERI"). At December 31, 1998, the net
assets of these subsidiaries was $51,551.

    Maine Energy, PERC and TERI are subject to the provisions of various
federal, state, local and provincial energy laws and regulations, including the
Public Utility Regulatory Policy Act of 1978, as amended. In addition, federal,
state and local environmental laws establish standards governing certain aspects
of the Company's operations. The Company believes it has all permits, licenses
and approvals necessary to operate.

2. RESTATEMENT

    The Company's balance sheets as of December 31, 1998 and 1997 and the
related statements of operations, stockholders' equity and cash flows for each
of the three years in the period ended December 31, 1998 have been restated. The
restatement is a result of the Securities and Exchange Commission's review of
the Company's proxy materials related to the prospective merger with Casella
Waste Systems (See note 21). The restatement relates to revenue recognized as a
result of the restructuring of a power purchase agreement and the sale of
electric generating capacity by two of the Company's majority-owned subsidiaries
with its customers, BHE and CMP, which were completed in 1998 and 1996,
respectively (See notes 4 and 5). At the time of these transactions, the Company
had recognized revenues representing a portion of the cash received in 1996 and
the total consideration received in 1998. After discussions with the staff of
the Securities and Exchange Commission, the Company agreed to defer these
amounts and recognize them over the term of the respective power purchase and
capacity purchase agreements to comply with generally accepted accounting
principles. In addition, performance credits previously reported as expense have
been reclassified as a reduction of

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

    The consolidated financial statements include the accounts of KTI and its
wholly-owned and majority-owned subsidiaries. All significant intercompany
accounts and transactions are eliminated in consolidation. As described in
Note 6, during 1997 the Company acquired in two transactions certain limited
partnership interests in PERC aggregating 64.29%. Prior to these transactions,
the Company was a 7.00% owner and the managing general partner of PERC. As a
result of the Company's aggregate ownership interest, PERC's financial
statements have been included in the Company's consolidated statement of income
for the year ended December 31, 1997. The consolidated statement of income
includes PERC's operations for the year ended December 31, 1997 as though the
acquisition had occurred at the beginning of the year and includes adjustments
to eliminate minority interest and the pre-acquisition earnings of PERC
attributable to the partnership interests acquired as of the respective dates.
Prior to 1997, the Company's investment in PERC was accounted for under the
equity method based on the Company's significant influence over its financial
and operating policies.

    The ownership interest of minority owners in the equity and earnings of the
Company's less than 100 percent-owned consolidated subsidiaries is recorded as
minority interest.

CASH EQUIVALENTS

    The Company considers all highly liquid investments with an original
maturity of 90 days or less when purchased to be cash equivalents.

RESTRICTED FUNDS

    Restricted funds consist of cash and cash equivalents held in trust, all of
which are available, under certain circumstances, for current operating
expenses, debt service, capital improvements and repairs and maintenance in
accordance with certain contractual obligations and cash deposited in a bank in
connection with certain of the Company's debt and standby letter of credit
obligations. Restricted funds available for current operating and debt service
purposes are classified as current assets.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
SIGNIFICANT CUSTOMERS AND CONCENTRATIONS OF CREDIT RISK

    Within the Waste-to-Energy segment, Maine Energy, PERC and TERI each sell
electricity to the local electric utility in their respective geographic
locations (Central Maine Power Company, ("CMP"), Bangor Hydro Electric Company
("BHE") and Florida Power Company ("FPC"), respectively). Electric power revenue
from such utilities during 1998 totaled approximately $19,326, $14,676 and
$5,593, respectively, and $18,780, $17,492 and $5,126, respectively, in 1997 and
$21,441 in 1996 for CMP. Accounts receivable from CMP, BHE and FPC were $1,393,
$3,166 and $472, respectively, at December 31, 1998 and $2,163, $3,212 and $454,
respectively, at December 31, 1997. In addition, Maine Energy and PERC earn
substantial portions of their waste handling revenues from municipalities in
their respective geographic regions in the state of Maine. TERI also earns a
significant portion of its revenue from a large national paper manufacturer.
Such revenues are earned under the terms of long-term agreements. American Ash
Recycling of Tennessee, Ltd. ("AART") earns a substantial portion of its
revenues as the result of a contract with the City of Nashville, Tennessee.

    Although less than 10% of consolidated revenue, a significant portion of
sales of recyclables in the Commercial segment is to international (including
Pacific Rim countries, South America and Europe) and domestic paper
manufacturers. The Company performs periodic credit evaluations of these
customers. Although the Company's exposure to credit risk associated with
non-payment by paper manufacturers is affected by conditions within the paper
industry and the general economic condition of countries within the Pacific Rim,
South America and Europe, a significant portion of outstanding receivables are
supported through letters of credit either issued, confirmed or discounted by
banks located in the United States. No single paper manufacturer or customer
exceeded 5% of the Company's total accounts receivable at December 31, 1998.

    Although less than 10% of consolidated revenue, a significant portion of
sales in the Residential Recycling segment is to two customers. The facilities
within the Residential Recycling segment operate under long-term contracts with
the local municipalities or contract waste haulers. This segment earns a portion
of its revenues from these municipalities and waste haulers within the
geographic region surrounding the respective facilities. In addition, the
Residential Recycling segment enters into long-term contracts to sell recyclable
materials at prices based on market price with a contractual floor. These
contracts have terms from one to ten years and expire through 2008. No
individual municipality or customer under long-term commodity contracts exceeded
5% of the Company's total accounts receivable at December 31, 1998.

    Although less than 10% of consolidated revenue, a significant portion of
sales in the Finished Products segment is to one customer. This customer is
under a contract to purchase a specified quantity of product at rates that
approximate market value through August, 2000. In addition, a significant
portion of this segment's sales are to manufacturers of manufactured homes and
insulation contractors throughout the United States and thus the revenues are
impacted by sales of new homes, which are cyclical in nature. No individual
customer of this segment exceeded 5% of the Company's total accounts receivable
at December 31, 1998.

    Other financial instruments which subject the Company to concentrations of
credit risk are cash and cash equivalents including restricted funds. The
Company restricts its cash investments to financial institutions with high
credit standings and securities backed by the United States Government.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INVENTORIES

    Inventories, consisting of secondary fibers, recyclables ready for sale and
certain finished products, include costs paid to third parties for purchased
materials and are stated at the lower of cost (first-in, first-out) or market.
Inventories consisted of finished goods of approximately $4,065 and $1,219 at
December 31, 1998 and 1997 respectively, and raw material of approximately $801
at December 31, 1998.

PROPERTY, EQUIPMENT AND LEASEHOLD IMPROVEMENTS

    Property, equipment and leasehold improvements are stated at cost, less
accumulated depreciation and amortization. All costs incurred for additions and
improvements, including interest during construction, are capitalized. The
Company capitalized net interest costs of $285, $20 and $110, in 1998, 1997 and
1996, respectively. Depreciation of property and equipment is provided using the
straight-line method over the estimated useful lives ranging principally from
three to twenty-five years. Assets under capital leases are amortized using the
straight-line method over the estimated useful lives ranging from five to ten
years. Amortization of assets under capital leases is included in depreciation
expense. Leasehold improvements are amortized on a straight-line basis over the
shorter of the term of the lease or the estimated useful life of the
improvement.

GOODWILL

    Goodwill represents costs in excess of net assets of businesses acquired in
purchase transactions. Goodwill is being amortized on a straight-line basis over
periods up to thirty years.

DEFERRED FINANCING COSTS

    Costs incurred in connection with debt and letter of credit financings are
deferred and are being amortized over the life of the related debt or letter of
credit issues using the interest method. The unamortized portion of such costs
related to the previously outstanding PERC bonds in 1998 and the Maine Energy
bonds in 1996 were included in the determination of the extraordinary loss.

DEFERRED PROJECT DEVELOPMENT COSTS

    The Company defers certain external costs incurred in the development of new
projects including design and costs related to obtaining required permits.
Amortization of these costs begins when the project becomes operational. If
management concludes that the related project will not be completed, the
deferred costs are expensed immediately.

REVENUE RECOGNITION

    Revenues from the sale of electricity to local utilities are recorded at the
contract rate specified in each entity's power purchase agreement ("PPA") as it
is delivered. Revenue includes the portion of the deferred gain on the sale of
electric generating capacity at Maine Energy (see Note 5) which is being
amortized on a straight-line basis over the term of the capacity agreement
(eleven years). Revenue also

         (IN THOUSANDS OF DOLLARS, EXCEPT SHARE AND PER SHARE AMOUNTS)

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
includes the amortization of the customer advance at PERC (see note 4) which is
being amortized on a straight-line basis over the term of the Power Purchase
Agreement (nineteen years).

    Revenues from waste processing consist principally of fees charged to
customers for waste disposal. Substantially all waste processing revenues are
earned from customers located in a geographic region proximate to the respective
facility. Revenue is generally recorded upon acceptance and in certain cases is
based on rates specified in long-term contracts. Certain of these rates are
subject to adjustment based on the levels of certain costs and expenses, as
defined, of Maine Energy and PERC. The Company periodically reviews the
long-term contracts and any anticipated losses are charged to operations in the
period the losses are first determinable. The Company's evaluation is based on
estimated revenues and direct costs related to the respective contracts.

    Revenues from the sale of recycled materials ($72,130, and $17,004 in 1998
and 1997, respectively) and finished products are recognized upon shipment.
Rebates to certain municipalities based on sales of recyclable materials are
recorded upon the sale of such recyclables to third parties and are included in
cost of operations. Revenues for processing of recyclable materials are
recognized upon delivery of recycled materials to the Company and totaled $7,791
and $690 in 1998 and 1997, respectively.

    Management fees from affiliates for 1996, related to providing general
partner services to PERC, were recognized in accordance with the partnership
agreement and were included in waste processing revenues. Such amounts have been
eliminated in consolidation for 1998 and 1997. Service and other revenues in
connection with transportation and waste management are recognized upon
completion of the services.

INCOME TAXES

    Deferred income taxes are determined using the liability method. Under this
method, deferred tax assets and liabilities are determined based on differences
between financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.

BUSINESS COMBINATIONS

    The Company has accounted for all business combinations under the purchase
method of accounting. Under this method, the purchase price is allocated to the
assets and liabilities of the acquired enterprise as of the acquisition date (to
the extent of the Company's ownership interest) based on their estimated
respective fair values and are subject to revision for a period not to exceed
one year from the date of acquisition. The results of operations of the acquired
enterprise are included in the Company's consolidated financial statements for
the period subsequent to the acquisition.

EVALUATION OF LONG-LIVED ASSETS

    The Company assesses long-lived assets for impairment, including goodwill
associated with assets acquired in a business combination when events or
circumstances exist that indicate the carrying amount of those assets may not be
recoverable. The Company performs an evaluation comparing the estimated future
undiscounted cash flows associated with the asset to the asset's carrying amount
to determine if a write-down to market value or discounted cash flow value is
required. No such events or circumstances existed at December 31, 1998.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

RECENT ACCOUNTING DEVELOPMENTS

    Recent accounting pronouncements which are not required to be adopted at
December 31, 1998, include the following Statement of Financial Accounting
Standards ("SFAS") and the American Institute of Certified Public Accountants
Statements of Position ("SOP"):

    SFAS No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES,
which will be required to be adopted by the Company as of January 1, 2001,
establishes standards for derivative instruments, including those embedded in
other contracts and for hedging activities. The new standard requires the
Company to recognize all derivatives as either assets or liabilities and measure
those instruments at fair value. Management believes that the adoption of SFAS
No. 133 will not have a material impact on the Company's financial statements.

    SOP 98-1, ACCOUNTING FOR COSTS OF COMPUTER SOFTWARE DEVELOPED OR OBTAINED
FOR INTERNAL USE is required to be adopted by the Company as of January 1, 2000.
The Company's current policy falls within the guidelines of SOP 98-1. Also, SOP
98-5, REPORTING ON THE COSTS OF START-UP ACTIVITIES is required to be adopted by
the Company as of January 1, 1999. Management believes that the adoption of SOP
98-5 will not have a material impact on the Company's financial statements.

RECLASSIFICATIONS

    Certain prior year amounts have been reclassified to conform with the

4. AMENDMENT OF PERC'S POWER PURCHASE AGREEMENT AND WASTE DISPOSAL AGREEMENTS

    On June 26, 1998, PERC completed an amendment of its PPA with BHE. At
closing, PERC received $6,000 in cash and BHE agreed to make 16 quarterly
payments of $250 commencing October 1, 1998 (the "BHE Note"). For financial
statement purposes, the BHE Note has been discounted using an effective interest
rate of 5.45%. The $6,000 cash payment and the present value of the BHE Note
($3,572) are being accounted for as a customer advance. Imputed interest on the
BHE Note is being amortized over its term and is included in interest income. In
addition, BHE issued the Company warrants to purchase 712,857 shares of BHE
common stock at an exercise price of $7.00 per share, exercisable 25% annually
with an expiration date of June 26, 2008. The estimated aggregate fair value of
these warrants at the date of issuance was approximately $3,814 ($5.35 per
share) which was also recorded as a customer advance. The customer advance, net
of transaction costs, is being amortized over the life of the PPA with BHE (19
years). As of December 31, 1998 the remaining customer advance in connection
with this transaction was approximately $12,788.

    In connection with the amendment, PERC's waste disposal agreements with
certain municipalities (the "Amending Charter Municipalities") were amended to
extend the term of such agreements to 2018. In addition, PERC granted the
Amending Charter Municipalities the right to purchase up to a 50% limited
partnership interest in PERC for an aggregate purchase price of $31,000. Such
purchases may only be made to the extent of their respective share of
distributable cash from PERC, as defined, and one-half of the quarterly payments
to be made under the BHE Note. Any such amounts paid by the Amending Charter
Municipalities must be used to prepay PERC's outstanding bonds payable. The
Amending Charter Municipalities were also granted the right to purchase the
remaining partnership interests in 2018 at the then fair market value, as
defined.

    The waste disposal agreements were further amended to provide that the
Amending Charter Municipalities, BHE, and partners in PERC would each receive
one-third of PERC's cash flows, as defined. Prior to this amendment, the
municipalities received one-half PERC's distributable cash, as defined. Based on
PERC's cash flow, as defined, distributable cash of approximately $4,616 and
$1,101 was payable for 1998 and 1997, respectively. Of these amounts,
approximately $413 and $1,101 remained unpaid as of December 31, 1998 and 1997,
respectively, and was included in accrued expenses.

    Under the PPA, PERC is required to deliver at least 105,000,000 kWh to BHE
in any Calendar year. In the event PERC fails to deliver this output, PERC is
obligated to pay $4 for each 1,000,000 kWh by which such deliveries fall below
105,000,000 kWh.

5. SALE OF ELECTRIC GENERATION CAPACITY AND RESTRUCTURE OF POWER PURCHASE
AGREEMENT

    On May 3, 1996, Maine Energy completed a restructuring of its PPA with CMP
and the sale of the rights to its electrical generating capacity to CL Power
Sales One, L.L.C. ("CL One"). At closing, Maine Energy received a payment from
CL One of $85,000 ("Capacity Payment") and the PPA was amended to reflect a
reduction in CMP's purchase price for electric power. In addition, the term of

5. SALE OF ELECTRIC GENERATION CAPACITY AND RESTRUCTURE OF POWER PURCHASE
AGREEMENT (CONTINUED)
PPA was extended from 2007 to 2012. The Company also received reimbursement of
certain transaction costs, including interest on the Capacity Payment from
November 6, 1995 to closing and certain other payments. The Company recorded the
payment from CL One, net of transaction costs, of approximately $80,691 as
deferred revenue in 1996. This amount is being recognized on a straight-line
basis as revenue over the life of the capacity agreement with CL One (eleven
years). As of December 31, 1998 and 1997 the remaining deferred revenue was
$61,276 and $68,556, respectively.

    Under the terms of the agreements, Maine Energy will be liable to CMP for
liquidated damages of $3,750 for any calendar year through the year 2006 and on
a pro rata basis for the period from January 1, to May 31, 2007 in which it does
not deliver at least 100,000,000 kilowatt hours ("kWh"). Also, if during the
same period, Maine Energy fails to deliver at least 15,000,000 kWh in any
calendar year through the year 2006 and on a pro rata basis for the period from
January 1, to May 31, 2007 it will be liable to CMP for liquidated damages of
$3,750 times the number of years remaining in the term of the agreement. Both
the 100,000,000 kWh and the 15,000,000 kWh levels are adjusted in the case of a
force majeure event, as defined. Maine Energy produced approximately 166,000,000
and 168,000,000 kWh of electricity in each of 1998 and 1997, respectively. In
order to secure CMP's right to liquidated damages, Maine Energy has obtained an
irrevocable letter of credit in the initial amount of $45,000 which will be
reduced by $3,750 for each completed year in which no event requiring the
payment of liquidated damages occurs. Under the terms of the letter of credit
agreement, Maine Energy is required to maintain certain restricted funds. The
letter of credit is collateralized by liens on substantially all of Maine
Energy's assets.

    Maine Energy used the proceeds from the sale of its capacity to repay the
then outstanding Maine Energy Resource Recovery Bonds and to retire the related
bank letter of credit. This prepayment resulted in the recognition of an
extraordinary loss of $2,248 (net of minority interest of $2,213) in 1996.

6. ACQUISITIONS

1998 ACQUISITIONS

    The Company acquired ten companies and an additional partnership interest in
one company during 1998. Payment of the aggregate purchase price for these
acquisitions consisted of (i) 1,945,353 shares of the Company's common stock at
a weighted-average value of $19.06 per share (based on the closing prices of the
common stock on the date of announcement of each acquisition); (ii) $57,909 in
cash (net of cash acquired of $6,198); (iii) a promissory note in the principal
amount of $1,086; and (iv) warrants to purchase 130,000 shares of common stock
valued at approximately $1,060 as of the date of acquisition. These acquisitions
were accounted for as purchases, and accordingly, the assets and liabilities of
the acquired entities have been recorded at their estimated fair value at the
dates of acquisition. The excess of the purchase price over the fair value of
the acquired net assets aggregating $102,866 has been recorded as goodwill and
is being amortized on a straight line basis over 30 years. The more significant
1998 acquisitions are described below.

    In August 1998, the Company acquired FCR, Inc. ("FCR") a diversified
recycling company that provides residential and commercial recycling, processing
and marketing services and primarily manufactures cellulose insulation and

(based on the closing price of the common stock on the date of announcement) and
(ii) $31,074 in cash. An additional payment of up to $30,000 may have been
required based on the earnings of FCR for the period July 1, 1998 through
December 31, 1998 (the "Earnout"). Based on FCR's earnings during the period, no
payments are due under the Earnout. The cost of the acquisition exceeded the
fair value of the acquired net assets by approximately $70,032.

    In August 1998, the Company acquired certain assets and assumed certain
liabilities of Atlantic Coast Fibers, Inc. ("Atlantic Coast") and Gaccione
Bros. & Co., Inc. and PGC Corporation (collectively, "Gaccione"). Atlantic Coast

(based on the closing price of the common stock on the date of the
announcement), (ii) $6,995 in cash and (iii) warrants to purchase 20,000 shares
of common stock valued at approximately $153 as of the date of acquisition.
Gaccione operated a high-grade paper processing facility. Payment of the

$1,086. In September 1998, the Company agreed to a payment of an additional
purchase price for Atlantic Coast and Gaccione consisting of 150,000 shares of
common stock. The Company recorded this additional purchase price as a liability
and an addition to goodwill. Subsequent to year-end, the Board of Directors
approved the payment of the additional purchase price and the common stock was
issued. The cost of these acquisitions exceeded the fair value of the acquired
net assets by approximately $18,104.

    In June 1998, the Company acquired Multitrade Group, Inc. ("Multitrade").
Multitrade operates three waste-to-energy facilities utilizing biomass and coal
to produce steam for sale to major industrial users under long-term contracts.
Payment of the purchase price, including all direct costs, for Multitrade was
$12,347 in cash. The cost of the acquisition exceeded the fair value of the
acquired net assets by approximately $4,537.

    In December 1998, the Company acquired an additional 9.6% limited
partnership interest in Maine Energy from one of the existing limited partners.
The cost of the acquisition was $2,410. The transaction has been accounted for
under the purchase method of accounting and the cost of the purchase price has
been allocated to the assets and liabilities of Maine Energy (to the extent of
the Company's additional ownership interest) based on their estimated fair
values as of the date of acquisition and resulted in an increase in the carrying
value of property and equipment of approximately $1,670.

1997 ACQUISITIONS

    On September 30, 1997 and November 12, 1997, the Company purchased certain
limited partnership interests in PERC aggregating 64.29% from one of the
existing limited partners. The aggregate cost of the acquisitions was $14,500.

the extent of the Company's additional ownership interest) based on their
estimated fair values as of the date of acquisition and resulted in a reduction
in the carrying value of

property and equipment of approximately $8,038. Prior to the acquisition of the
additional 64.29% limited partnership interest, the Company accounted for its 7%
ownership under the equity method. The excess of the Company's actual capital
contributions over its original 7% ownership interest in the partnership's total
contributed capital is being amortized over the term of the partnership's energy
sales contract. This amount is included in goodwill.

    In November, 1997, the Company acquired certain assets and assumed certain
liabilities of Prins Recycling Corp. and its subsidiaries ("Prins") pursuant to
an order of the Bankruptcy Court for the District of New Jersey. Prins was
engaged in the operation of three material recycling facilities located in or
proximate to Newark, New Jersey, Chicago, Illinois and Charlestown,
Massachusetts. The aggregate purchase price including all direct costs was
approximately $15,100 and included warrants to purchase 92,250 shares of the
Company's common stock at exercise prices ranging from $8.10 to $9.25 per share.
The warrants are exercisable at any time and expire on various dates between
December 31, 1999 and April 30, 2002. During 1998 and 1997, 40,000 and 17,325 of
these warrants were exercised. At December 31, 1998, 34,925 of these warrants
remain outstanding. In connection with the transaction, the Company assumed
certain administrative claims against Prins. The cost of the acquisition
exceeded the fair value of the acquired net assets by approximately $6,374 which
has been recorded as goodwill and is being amortized on a straight line basis
over 15 years. During 1998, the Company finalized its allocation of the purchase
price which resulted in certain changes in estimated liabilities as of the
acquisition date, including certain additional administrative claims against
Prins and fair values assigned to property, equipment and leasehold
improvements. Such adjustments resulted in an increase in goodwill of
approximately $1,865.

    On September 19, 1997, the Company acquired all of the outstanding common
stock of K-C Industries, Inc. ("K-C"). K-C is engaged in the marketing of paper
and secondary fibers. The aggregate purchase price, including all direct costs,
was approximately $6,739 and included 425,014 shares of the Company's common
stock. The cost of the acquisition exceeded the fair value of the acquired net
assets by approximately $5,035 which has been recorded as goodwill and is being
amortized on a straight line basis over 15 years.

    In August, 1997, the Company acquired all of the outstanding common stock of
I. Zaitlin and Sons, Inc. ("Zaitlin"), a company engaged in the recycling
business in Maine, and Data Destruction Services, Inc., a company engaged in the
destruction of confidential records. The aggregate purchase including all direct
costs was approximately $2,245 and included 200,000 shares of the Company's
common stock. The cost of the acquisition exceeded the fair value of the
acquired net assets by approximately $2,498 which has been recorded as goodwill
and is being amortized on a straight line basis over 10 years. During 1998, the
Company finalized its allocation of the purchase price which resulted in certain
changes in estimated liabilities as of the acquisition date. Such adjustments
resulted in an increase in goodwill of approximately $105 during 1998.

    In June, 1997, the Company acquired the entire general partnership interest
in AARNE from the existing general partner. The aggregate cost of the
acquisition was $560 which exceeded the carrying value of the minority interest
by approximately $328 which was recorded as goodwill and is being amortized on a
straight line basis over 15 years. Subsequent to the acquisition, the Company
owns 100% of AARNE.

1996 ACQUISITIONS

    On May 3, 1996, the Company purchased additional limited partnership
interests in Maine Energy aggregating 23.77% from certain other existing limited
partners. The aggregate cost of the acquisitions was approximately $485.
Subsequent to this acquisition, the Company's ownership in Maine Energy
aggregated 74.15%. Prior to September 16, 1994 (the date at which the Company
acquired its initial limited partnership interests and became majority owner in
Maine Energy), the Company accounted for its 10% ownership interest under the
equity method. The difference between the Company's actual capital contributions
and its ownership interest in the partnership's total contributed capital is
being amortized over the term of the partnership's energy sales contract. This
amount is included in goodwill.

    During the fourth quarter of 1996, the Company acquired all of the
outstanding common stock of Timber Energy Investments, Inc. ("TEII"). TEII,
through its subsidiaries, is engaged in the generation of electricity and the
processing of wood and plastic materials. The purchase price, including all
direct costs, was approximately $2,142. The cost of the acquisition exceeded the
fair value of TEII's net assets by approximately $2,035 which has been recorded
as goodwill and is being amortized on a straight line basis over 10 years.
During 1997, the Company finalized its allocation of the purchase price which
resulted in certain changes in the fair values assigned to property, equipment
and leasehold improvements and the reduction of certain assumed liabilities.
Such adjustments resulted in an increase of goodwill of approximately $229.

    On March 31, 1996, the Company acquired a 60% limited partnership interest
in American Ash Recycling Co. of Tennessee, a limited partnership, ("AART").
AART is engaged in the processing of ash residue from a waste-to-energy facility
located in Nashville, Tennessee. The purchase price for the limited partnership
interest was $2,100. The cost of the acquisition exceeded the fair value of

stock of Manner Resins, Inc. ("Manner") a company engaged in the purchase and
sale of recyclable plastic materials. The purchase price was approximately $456
and was entirely financed through the issuance of 65,000 shares of the Company's
common stock. The cost of the acquisition exceeded the fair value of Manner's
net assets by approximately $421 which has been recorded as goodwill and is
being amortized on a straight line basis over 5 years.

    Beginning October 1, 1996 Maine Energy revised the estimated average useful
lives used to compute depreciation for substantially all of its plant and
equipment. These revisions were made to more properly reflect the remaining
useful lives of the assets. The change had the effect of increasing income
before extraordinary item and net income by approximately $482 ($.08 per share,
basic and $.07 diluted per share) for 1996.

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

    (A) During July 1998, the Company entered into a Revolving Line of Credit
       Agreement with a bank (the "Credit Agreement") which provides for
       borrowings of up to $150,000. The Credit Agreement expires in
       April 2001. The Company may select interest rates on the outstanding
       borrowings based on the bank's prime rate or LIBOR rates. The interest
       rates range from the bank's prime rate to the bank's prime rate plus
       0.75% or LIBOR rates plus 1.75% to LIBOR rates plus 2.50% depending on
       the attainment of certain financial covenants, as defined in the Credit
       Agreement. All borrowings under the Credit Agreement at December 31, 1998
       were at LIBOR plus 2.50% (8.05% at December 31, 1998). The Credit
       Agreement also provides standby letters of credit which reduce the total
       borrowings available to the Company. At December 31, 1998, approximately
       $2,275 in standby letters of credit were outstanding and the Company had
       approximately $9,097 in available borrowings under the Credit Agreement.
       All borrowings under the Credit Agreement are secured by substantially
       all of the Company's assets which have not been pledged for other
       borrowings or certain standby letters of credit. Among other things, the
       Credit Agreement restricts the Company's ability to incur additional
       indebtedness and requires it to maintain certain financial ratios. At
       December 31, 1998, the Company was in default of a debt covenant and
       received a waiver from the bank for this default. Certain borrowings
       under this Credit Agreement were utilized to repay the revolving and term
       loan payable discussed below.

9. DEBT (CONTINUED)
       On May 12, 1999, the Company executed an amendment to the Credit
       Agreement (the "Amended Agreement") modifying certain financial covenants
       and requiring bank approval for all acquisitions. The Amended Agreement
       requires that the Company and certain subsidiaries, as defined, maintain
       certain specified financial covenants, including, a minimum interest
       coverage ratio, a maximum funded debt to EBITDA ratio, a minimum fixed
       charge coverage ratio, and a maximum debt to capitalization ratio, each
       as defined in the Amended Agreement. The Company's ability to satisfy
       these covenants is dependent on its ability to substantially achieve its
       operating plan. As of June 30, 1999, the Company was in default of
       certain of these covenants and received a waiver from the bank for this
       default through January 1, 2000. The Company will continue to select
       interest rates on the outstanding borrowings based on the banks prime
       rate or LIBOR rates, however, the interest rates range from the bank's
       prime rate to the bank's prime rate plus 1.50% or LIBOR plus 1.88% to
       LIBOR plus 3.25% depending on the attainment of a financial covenant, as
       defined, in the Amended Agreement.

       During 1997, the Company had entered into an Amended and Restated
       Revolving and Term Loan and Security Agreement with the same bank which
       provided an $11,000 revolving credit facility and $7,500 term loan. At
       December 31, 1997, $5,000 and $7,411 were outstanding under the revolving
       credit facility and term loan, respectively. The revolving line of credit
       interest was at the bank's prime rate plus 0.75% (8.75% at December 31,
       1997) payable monthly. The term loan bore interest at the bank's prime
       rate plus 1.25% (9.25% at December 31, 1997), and was due in monthly
       installments of $89 plus interest. These obligations were repaid in
       July 1998.

    (B) The Company leases certain machinery and equipment under capital leases
       expiring at various times through 2008. These capital lease obligations
       have a weighted average interest rate of 9.46% at December 31, 1998 and
       monthly principal and interest payments totaling $129. These obligations
       are secured by machinery and equipment with a net carrying value of
       $6,702 at December 31, 1998.

    (C) A subsidiary of the Company has a $8,000 revolving line of credit
       (including $1,000 available for letters of credit) with a bank (the
       "Revolving Credit Agreement") which expires in May 2000. Borrowings under
       the Revolving Credit Agreement are based on eligible collateral which
       includes specified percentages of certain cash, accounts receivable and
       inventory, as defined. Interest on borrowings is at LIBOR rate plus 2.25%
       (weighted average rate of 7.78% and 9.50% at December 31, 1998 and 1997,
       respectively). Among other things, the Revolving Credit Agreement
       restricts the subsidiary's ability to incur additional indebtedness and
       requires it to maintain certain financial ratios, as defined.

    (D) Promissory note payable to sellers in a business transaction with
       interest at 7% and principal due in February 2001.

    (E) A subsidiary of the Company financed the construction of a facility by
       issuing bonds with a maturity date of November 1, 1999. Interest is
       payable monthly at a variable rate, as defined in the bond agreement
       (3.2% at December 31, 1998). The bonds contain certain restrictive
       covenants for the subsidiary including maintenance of certain financial
       ratios and minimum

       net worth requirements. The bonds are secured by the facility and the
       related equipment with an aggregate net carrying value of $2,138 at
       December 31, 1998. These bonds were paid in full subsequent to
       December 31, 1998.

    (F) The notes payable to various commercial lenders bear interest at rates
       between 7.90% and 12.5%, with a weighted average interest rate of 8.17%
       at December 31, 1998, with monthly payments of principal totaling $18.
       The notes mature at various dates through 2002. The notes are secured by
       equipment with an aggregate net carrying value of $2,201 at December 31,
       1998.

    (G) A subsidiary has a term loan payable to a private lender. The principal
       payments are $7 per month plus interest at 12.5% through May 2007.

    (H) During 1997, a subsidiary of the Company entered into a working capital
       and term financing agreement (the "Financing Agreement") with a bank. The
       balance outstanding at December 31, 1998, is under a $500 working capital
       loan which carries interest at the bank's prime rate plus 0.75% (8.50% at
       December 31, 1998), is secured by substantially all of the assets of the
       subsidiary and expires in April 1999. At December 31, 1997 the Financing
       Agreement included a term loan with an outstanding principal balance of
       $780, with interest at the bank's prime rate plus 1.25% (9.75%) and was
       secured by equipment with a carrying value of approximately $1,300; a
       5 year mortgage loan with an outstanding principal balance of $670, with
       interest at the bank's prime rate plus 1.25% (9.75%) and was secured by
       certain real estate with a carrying value of approximately $715; and $105
       outstanding under the working capital loan. The term loan and mortgage
       loan were repaid in full during 1998.

    (I) On April 1, 1997, the Company and a bank entered into a Second Amended
       and Restated Term Note for $607. The bank agreed to forgive $150 of the
       outstanding balance under the previous Amended and Restated Term Note.
       This amount is included in other income in 1997. The Second Amended and
       Restated Term Note was due in monthly installments of $38 plus interest
       at the bank's prime rate (8.5% at December 31, 1997). The obligation was
       repaid in full during 1998.

PERC BONDS PAYABLE

    On June 26, 1998, the Finance Authority of Maine ("FAME") issued $44,995 par
amount Finance Authority of Maine Electric Rate Stabilization Revenue Refunding
Bonds, Series 1998 A and Series B (Penobscot Energy Recovery Company, LP) (the
"1998 Bonds"). The proceeds of the 1998 Bonds were used to repay all of the
outstanding balance due on PERC's existing Floating Rate Demand Resource
Recovery Revenue Bonds (the "1986 Bonds"), which were called for redemption
during July 1998. The redemption resulted in the recognition of an extraordinary
loss of $351 (net of minority interest of $249 and tax of $267) which included
the unamortized portion of the deferred financing costs associated with the
original issuance. The 1998 Bonds are fixed rate bonds with yields ranging from
3.75% to 5.20% with a weighted-average yield of approximately 5.06%.

    The 1998 Bonds are subject to mandatory redemption in annual installments of
varying amounts through July 1, 2018. Beginning July 1, 2008, the 1998 Bonds are
subject to redemption at the option of

PERC at a redemption price equal to 102%, through June 30, 2009, 101% for the
period July 1, 2009 to June 30, 2010 and 100% thereafter of the principal amount
outstanding plus accrued interest.

    In conjunction with the refinancing, PERC entered into a loan agreement with
FAME, which contains various provisions including the maintenance of certain
restricted funds and certain restrictive covenants relating to the 1998 Bonds.
The covenants restrict PERC's ability to incur additional indebtedness and
restrict the ability of the general partners to sell, assign or transfer their
general partner interests. The bonds are collateralized by liens on
substantially all of PERC's assets

    In connection with the refinancing, the Company issued a $3,000 limited
guaranty of PERC's payment obligation under the Loan Agreement, in the favor of
FAME and the 1998 Bond Trustee. In addition, BHE also issued a guaranty to FAME
and the 1998 Bond Trustee in the amount equal to the annual payments for
principal and interest on the 1998 Bonds. Demands on the above guaranties are to
be on a pro-rata basis. If either party shall default under such demand, the
other guarantor is liable for the entire demand, up to the limit on such
guarantor's guaranty. In addition, the 1998 Bonds are insured by Financial
Security Assurance, Inc.

    At December 31, 1997, two series of the 1986 Bonds totaling $47,900 were
outstanding. The interest rates on the Revenue bonds were based on rates for
certain tax-exempt obligation, as determined weekly by the remarketing agent for
the bonds with a weighted-average interest rate of 4.32% at December 31, 1997.

TERI REVENUE BONDS PAYABLE

    During June 1997, TERI issued two series of 1997 Industrial Development
Revenue Bonds: Series A in the amount of $13,400 and Series B in the amount of
$308. The Series B bonds carried interest at 10% and were paid in full in
December 1997. The Series A bonds bear interest at 7.0%. The Series A bonds have
an annual sinking fund payment due each December, ($2,030 due December 1, 1999),
with final payment of $4,620 due December 2002. The bond agreements require,
among other things, maintenance of various insurance coverages and restrict the
borrowers ability to incur additional indebtedness. The bonds are collateralized
by liens on TERI's electric generating facility located in Telogia, Florida. The
proceeds from these bonds were utilized to repay certain then outstanding
indebtedness.

CONVERTIBLE SUBORDINATED NOTES

    During August 1998, the Company issued $21,099 of Convertible Subordinated
Notes (the "Convertible Notes") in exchange for substantially all the
outstanding shares of the Series B Preferred Stock. This exchange was made in
accordance with the original terms of the Series B Preferred Stock. The
Convertible Notes carry interest at 8.75% and are due in August 2004. In
accordance with the terms of the Convertible Notes established concurrently with
the issuance of the Series B Preferred Stock, the holders of Convertible Notes
have the option to convert the principal amount of the Convertible Notes into
shares of the Company's Common Stock at $11.75 per share. During November 1998,
$14,329 of the then outstanding Convertible Notes were converted to common
shares (see Note 11).

SUBORDINATED NOTES PAYABLE TO MAINE ENERGY LIMITED PARTNERS

    These notes, as amended, bear interest at 12%. Payments of principal and
interest are made solely at the discretion of Maine Energy's general partner.
However, all principal and interest must be repaid prior to any partner
distributions. To the extent interest is not paid, accrued interest is
capitalized. As a holder of a portion of the Subordinated Notes Payable, the
Company is entitled to receive a proportionate share of such payments. At
December 31, 1998 and 1997, Maine Energy had $12,880 and $14,307, respectively,
outstanding under the notes of which the Company held $8,587 and $2,358,

SERIES A PREFERRED STOCK

    In June 1997 the Company sold 487,500 shares of Series A Preferred Stock

renamed Series A Preferred ("Series A Preferred"). During the first quarter of
1998, all of the remaining 447,500 shares of the Series A Preferred were
converted into 447,500 shares of common stock.

    The Company accreted the carrying value of the Series A Preferred by $42 and
$228 in 1998 and 1997, respectively, representing periodic accretion to the
mandatory redemption value of $12.00 per share and $472 in 1997 which represents
the difference between the initial allocated value of the Series A Preferred and
the initial conversion rate.

    Certain of the Company's outstanding warrants contain provisions which allow
for the conversion of such warrants into a lesser number of shares without the
payment of cash into the Company (so-called "cashless exercise" provisions).
Accordingly, there can be no assurance that, even if all such warrants are
exercised, the Company will receive all the aggregate gross proceeds.

12. STOCK OPTION PLANS

    The Company has four stock option plans; the 1986 Stock Option Plan of KTI
(the "1986 Plan"), the KTI 1994 Long-Term Incentive Award Plan and the DataFocus
Long-Term Incentive Plan (collectively, the "1994 Incentive Plans") and the KTI
Directors Stock Option Plan (the "Directors Plan"). All plans are administered
by the Compensation Committee of the Board of Directors.

    The Company has elected to follow Accounting Principles Board Opinion
No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES ("APB 25") and related
Interpretations in accounting for its employee stock

12. STOCK OPTION PLANS (CONTINUED)
options because, as discussed below, the alternative fair value accounting
provided for under SFAS No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION, ("SFAS
No. 123") requires use of option valuation models that were not developed for
use in valuing employee stock options. Under APB 25, because the exercise price
of the Company's employee stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.

    Elements of the various plans include the following:

    THE 1986 PLAN. A maximum of 66,190 shares are subject to the 1986 Plan.
Options were granted at prices not less than the fair market value at the date
of grant. All options granted had 10 year terms and vested immediately. No new
options can be granted under this plan.

    THE 1994 INCENTIVE PLANS. A maximum of 1,383,333 shares are subject to grant
under the 1994 Incentive Plans. Options may be granted at prices not less than
the fair market value at the date of grant. All grants prior to January 1, 1998
primarily vest at 20% per year beginning one year from the date of grant. Grants
subsequent to January 1, 1998 vest ratably over a 60-month period beginning one
month from the date of grant. Vested options may be exercised at any time until
their expiration which may be up to ten years from the date of grant. Unvested
options are forfeited upon termination of employment.

    THE DIRECTORS PLAN. A maximum of 200,000 shares are subject to the Directors
Plan. Under the Directors Plan, non-employee Directors are automatically granted
non-statutory options on August 1 of each year. The number of shares granted is
equal to the lesser of (i) 7,500 shares or (ii) a number of shares having a
maximum market value of $68. Options granted may not be exercised within one
year of grant and have 10 year terms.

    In addition to the Plans described above, the Company's Board of Directors
from time to time has granted key employees non-plan options. During 1998 and
1997, the Board of Directors made non-plan option grants. These non-plan options
have a ten-year term, and were granted at the then current fair market value.
The 1997 grants vested on the date of grant. The 1998 grants had vesting
schedules ranging from immediate vesting to ratably over a 60-month period
beginning one month from the date of grant.

    Pro forma information regarding net income and earnings per share is
required by SFAS No. 123, and has been determined as if the Company had been
accounting for its employee stock options under the fair value method of that
statement. The fair value of these options was estimated at the date of grant
using a Black-Scholes option pricing model with the following assumptions for
1998, 1997 and 1996, respectively: weighted average risk-free interest rates of
5.5%, 5.9% and 6.5%; no dividends;

volatility factors of the expected market price of the Company's common stock of
 .517, .494 and .642; and weighted-average expected life of 5 years, 5 years and
8 years.

    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

    For purposes of pro forma disclosures, the estimated fair value of the
options granted subsequent to 1994 is amortized to expense over the options'
vesting period. The Company's pro forma information follows:

    The Tax Reform Act of 1986 enacted a complex set of rules limiting the
potential utilization of net operating loss and tax credit carryforwards in
periods following a corporate "ownership change". In general, for federal income
tax purposes, an ownership change is deemed to occur if the percentage of stock
of a loss corporation owned (actually, constructively and, in some cases,
deemed) by one or more "5% shareholders" has increased by more than
50 percentage points over the lowest percentage of such stock owned during a
three-year testing period. During 1994, such a change in ownership occurred. As
a result of the change, the Company's ability to utilize certain of its net
operating loss carryforwards and general business credits will be limited to
approximately $1,200 of taxable income, or approximately $375 of equivalent
credit per year. This limitation may be increased if the Company recognizes a
gain on the disposition of an asset which had a fair market value greater than
its tax basis on the date of the ownership change.

    The Company recorded net operating loss carryforwards of $25,580, $12,525
and $525 related to the acquisition of TEII, FCR and Total Waste
Management, Inc., respectively, which are also subject to a corporate "ownership
change". As a result of the change, the Company's ability to utilize the net
operating loss carryforwards are limited to approximately $989, $3,219 and $71
per year, respectively.

15. COMMITMENTS

    The Company has entered into various facility and equipment operating
leases. The facility lease agreements generally require the Company to pay
certain expenses including maintenance costs and a percentage of real estate
taxes. The leases expire at various times ranging through 2007. Rental expense
for all operating leases including facilities, amounted to approximately $3,747,
$1,192 and $145 for the years ended December 31, 1998, 1997 and 1996,
respectively. Included in the Company's operating leases are leases of certain
administrative offices from companies whose principals include certain officers
and shareholders of the Company. Rent expense under these leases was $708, $96
and $110 for the years ended December 31, 1998, 1997 and 1996, respectively. In
addition, the Company leases certain other office and operating facilities from
individuals who are shareholders and employees. As of

    The Company has entered into employment agreements with certain of its key
employees which provide for fixed compensation and bonuses based on operating
results, as defined. These agreements generally continue until terminated by the
employee or the Company and, under certain circumstances, provide for salary
continuation for a specified period. At December 31, 1998 the Company's maximum
aggregate liability under the agreements if all the employees were terminated by
the Company is $13,129.

    In connection with their operations, Maine Energy, TERI and PERC have
entered into certain contractual agreements with respect to the supply and
acceptance of municipal solid waste and the sale of electric power.

    In 2007, certain of Maine Energy's municipal customers have the right to
obtain a 20% interest in Maine Energy's cash flows, as defined in certain
agreements, to be applied against the municipalities' future waste disposal
costs.

    FCR Plastics, Inc. ("Plastics"), a subsidiary of FCR, has committed to fund
a maximum of $700 towards the construction of certain machinery and equipment on
behalf of a customer. The equipment will be located within Plastics facility and
the customer will repay the total cost of the equipment up to Plastics maximum
contribution of $700. Repayment of the notes will commence as soon as
installation of the equipment is complete.

    On December 31, the Company acquired a 35% interest in the Oakhurst
Company, Inc. ("Oakhurst") for approximately $900. Oakhurst is a public holding
company which owns two businesses which are distributors in the automotive
aftermarket. As part of this transaction, the Company assigned its interest in a
joint venture with Grace Brothers, Ltd. and SC Fundamental Investments L.P., the
majority bond holders of the Ford Heights, Illinois Waste Tire to Energy
Project, to own and operate this facility. Due to amendments to the Illinois
Retail Rate Act, which repealed certain incentives to the facility, it was
closed during startup testing and the owner sought protection under federal
bankruptcy laws. On December 28, the bankruptcy court in Delaware approved the
amended Plan of Reorganization which provided for the Company and the
bondholders each to own 50% of the reorganized entity which was renamed New
Heights Recovery & Power, LLC ("New Heights"). The bondholders converted $80.0
million in bonds and other claims into equity and KTI committed to investing up
to $17.0 million in equity for working capital, retrofitting and upgrading of
the facility. This commitment to New Heights was transferred to Oakhurst and the
Company has agreed to provide financing to Oakhurst. During 1998, the Company
advanced $1,500 to Oakhurst. This amount is included in notes
receivable-officers/shareholders and affiliates at December 31, 1998.

15. COMMITMENTS (CONTINUED)

    During 1997, FCR acquired a company whereby the former shareholder of the
Company may receive up to $2,000 of additional consideration. The amount of the
additional consideration will be based on the earnings of the Company for the
12 months ended April 30,1998 and 1999, as defined in the purchase agreement.
Any additional consideration will be recorded as an addition to goodwill. Of the
potential additional consideration $924 was advanced at closing and is recorded
as a note receivable from the former shareholder. Upon reaching the earnings
targets discussed above, this amount will be reclassified to goodwill.

16. EMPLOYEE BENEFIT PLAN

    The Company has established defined contribution employee savings and
investment retirement plans under Section 401(k) of the Internal Revenue Code
which cover substantially all employees after satisfying certain eligibility
requirements. The Company contributes on behalf of each participating employee
an amount as defined in the plans. The Company's contribution was approximately
$596, $290 and $164 for the years ended December 31, 1998, 1997 and 1996,
respectively. Included in the 1998, 1997 and 1996 Company contributions were
4,215, 4,117 and 4,322 shares, respectively, of the Company's common stock. The
4,322 shares contributed for 1996 were purchased by the Company from third
parties. The aggregate fair value of the stock was $41, $35 and $32,
respectively.

17. RELATED PARTY TRANSACTIONS

    The Company receives an annual management fee (adjusted annually for changes
in the Consumer Price Index) as co-general partner of PERC. During the year
ended December 31, 1996, the Company earned management fees of approximately
$418. All such amounts are eliminated in consolidation in 1998 and 1997.

    During 1998, the Company advanced $1,500 to New Heights with an interest
rate at 14%. The advance is due in 2001 and is recorded as a note
receivable-affiliate at December 31, 1998.

18. FAIR VALUE OF FINANCIAL INSTRUMENTS

    The estimated fair values of financial instruments have been determined by
the Company using available market information and appropriate valuation
methodologies. However, considerable judgment is required in interpreting market
data to develop the estimates of fair value. Accordingly, the estimates
presented herein are not necessarily indicative of the amounts the Company could
realize in a current market exchange. The carrying amount and estimated fair
values of financial instruments at December 31, 1998 and 1997 are summarized as
follows:

    The following methods and assumptions were used to estimate the fair value
of financial instruments:

    CASH, RESTRICTED CASH AND ACCOUNTS RECEIVABLE--the carrying amounts reported
in the balance sheet for cash, cash equivalents, restricted funds including debt
securities, and accounts receivable approximate their fair value.

    NOTES AND OTHER RECEIVABLES--the fair value is estimated using discounted
cash flow analyses, using appropriate interest rates.

18. FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)
    RESOURCE RECOVERY REVENUE BONDS PAYABLE--the fair value of bonds payable is
estimated using discounted cash flow analyses, using appropriate interest rates.

    OTHER DEBT--the fair value is estimated based on discounting the estimated
future cash flows using the Company's incremental borrowing rate for similar
debt instruments.

20. CONTINGENCIES

    The Company is a defendant in a consolidated purported class action, which
alleges violations of certain sections of the federal securities laws. The
Company believes the allegations are without merit and intends to defend the
litigation vigorously.

    Two lawsuits have been filed against a subsidiary of the Company and certain
of its officers, alleging fraud and tortious interference. The actions are based
on two contracts between the plaintiff and the subsidiary, which contracts
require all disputes to be resolved by arbitration. Arbitration proceedings have
commenced. The Company believes it has meritorious defenses to the allegations.

    The former majority shareholder of a company acquired by a subsidiary of the
Company instigated arbitration proceedings against the Company and two of its
subsidiaries, alleging the subsidiaries acted to frustrate the "earn-out"
provisions of the acquisition agreement and thereby precluding him from
receiving, or alternatively, reducing the sum to which he was entitled to
receive. He also alleges his employment agreement was wrongfully terminated. The
claim for arbitration alleges direct charges in excess of $5,000 and requests
punitive damages, treble damages and attorneys fees. The Company and its
subsidiaries have responded to the demand, denying liability and filed a
counterclaim for $1,000 for misrepresentations. The Company believes it has
meritorious defenses to the claims.

    The Company is involved in certain litigation arising from the normal course
of its business. In the opinion of management, the outcome of these matters
individually and in the aggregate will not have a material effect on the
Company's financial position, cash flows or results of operations.

21. SUBSEQUENT EVENTS

    On September 23, 1999, the Company entered into an amended Agreement and
Plan of Merger (the "Merger Agreement") with Casella Waste Systems, Inc.,
("Casella") a publicly-owned company engaged in the waste services industry.
This Merger Agreement was an amendment to the original agreement dated
January 12, 1999. The merger will be completed through the exchange of all of
shares of the Company's common stock for shares of Casella's Class A common
stock based on an exchange ratio specified in the Merger Agreement. In addition,
all of the Company's outstanding and unexercised stock options and stock
purchase warrants will be converted into similar rights to acquire Casella's
Class A common stock under the same terms and conditions and the same exchange
ratio. Subsequent to the completion of the merger the current Casella
stockholders will own a majority of the combined company. Under the terms of the
Merger Agreement, Casella is required to file a registration statement with the
Securities and Exchange Commission to register the shares of its Class A common

stock to be issued in the Merger. The merger is subject to, among other things,
approval of the Company's and Casella's stockholders. No assurances can be given
that the remaining conditions of the merger will be satisfied and that the
merger will be consummated. In connection with the merger, Casella has agreed to
reimburse the Company for its investment banking fees and other merger related
costs and as of December 31, 1998, approximately $1,160 of merger related costs
have been deferred.

    During January 1999, the Company completed the acquisition of AFA
Group, Inc. and subsidiaries, an integrated wood waste processing and hauling
business. The purchase price was approximately $9.0 million.

    During March 1999, the Company signed a definitive agreement to acquire a
company which operates a material recovery facility. The acquisition is expected
to close on June 30, 1999 upon the resolution of a contingency, as outlined in
the purchase agreement. The purchase price is expected to be approximately
$5,600 of which $250 was paid at the signing of the definitive agreement.

                         NOTES TO FINANCIAL STATEMENTS

                               DECEMBER 31, 1996

1. ORGANIZATION AND DESCRIPTION OF OPERATIONS

    Penobscot Energy Recovery Company, Limited Partnership ("PERC") is a limited
partnership formed on December 28, 1983 and organized to design, construct,
operate, own and manage a facility located in Orrington, Maine for the
conversion of solid waste and supplemental fuel to electric power (the
"Project"). Certain contractual agreements relating to this facility have been
entered into, including agreements with respect to the supply of solid waste,
the sale of electric power, and operation and maintenance of the facility.

    PERC Management Company ("PMC"), which is ultimately owned by KTI, Inc.
("KTI"), and Energy National, Inc. ("ENI") are general partners. As of
December 31, 1996, ENI and another entity were limited partners. As of
December 31, 1996, the ownership interests of the partners were as follows:

</TABLE>

    Profits and losses are to be allocated 10% to the general partners and 90%
to the limited partners until such time that the return on equity, as defined in
the Partnership Agreement, of the limited partners exceeds their aggregate
capital contributions. Commencing on that date and continuing through the
remaining term of the Partnership, such allocations, including gains and losses
upon net sale or refinancing, shall be 40% to the general partners and 60% to
the limited partners.

    According to the Partnership agreement, the Partnership has a limited life
extending to December 31, 2018, unless further extended by a vote of all of the
partners.

    The Project is subject to the provisions of various federal and state energy
laws and regulations including the Public Utility Regulatory Policies Act of
1978, as amended. In addition, federal, state and local environmental laws
establish standards governing certain aspects of the Project's operations. The
Company believes it has all permits, licenses and approvals necessary to operate
the facility.

2. SIGNIFICANT ACCOUNTING POLICIES

PROPERTY, PLANT AND EQUIPMENT

    Property, plant and equipment are stated at cost, less accumulated
depreciation. All costs incurred for additions and improvements to the facility,
including interest during construction, are capitalized.

    Depreciation is provided on the straight-line method over estimated useful
lives.

                               DECEMBER 31, 1996

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
DEFERRED COSTS

    Costs incurred by PERC in connection with permanent financings have been
deferred and are being amortized over the life of the related debt issues using
the interest method.

    During 1991, PERC finalized negotiations with municipalities and entered
into new long-term waste handling agreements which resulted in higher waste
handling fees. Costs associated with the renegotiation were deferred and
amortized over 60 months which represented the minimum period covered by the new
agreements.

REVENUES

    Electric power revenues are earned from the sale of electricity to Bangor
Hydro-Electric Company ("BHE"), a utility serving a portion of the State of
Maine, under a Power Purchase Agreement (the "Agreement"). Revenue is recorded
at the contract rate specified in the Agreement as the electricity is delivered.

    Waste processing revenues consist principally of fees charged to customers
for waste disposal. Substantially all waste processing revenues are earned from
customers located in a geographic region proximate to the facility. Revenue is
generally recorded upon delivery based on rates specified in the applicable
long-term contracts. Certain of these contract rates are adjusted quarterly
based on actual costs incurred in the prior quarter.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

INCOME TAXES

    There is no provision in the financial statements for income taxes as the
income or loss is included in the income tax returns of the partners.

STATEMENTS OF CASH FLOWS

    For purposes of the statements of cash flows, PERC considers all highly
liquid debt instruments purchased with a maturity of three months or less to be
cash equivalents.

RECLASSIFICATIONS

    Certain amounts have been reclassified to conform with the 1998 presentation
of KTI.

</TABLE>

4. RELATED PARTY TRANSACTIONS

    PERC incurred management fees payable to the general partners of $595 in
1996, in accordance with the Partnership Agreement. PERC purchases a portion of
its supplemental fuel (wood chips) from KTI BioFuels, L.P., an affiliate of PMC.
During 1996, these purchases totaled approximately $279.

    Effective May 1, 1989, PERC entered into an Operation and Maintenance
Agreement with ESOCO Orrington, Inc., an affiliate of ENI. For the year ended
December 31, 1996, PERC paid operating and maintenance fees to ESOCO of
approximately $4,500, plus additional approved pass through operating costs.

    PERC had waste processing revenue of approximately $615 from Orrington
Waste Ltd. (a limited partnership including certain general and limited partners
of PERC) (OWL) in 1996. OWL and PERC have a long-term put-pay agreement under
which OWL pays waste disposal fees to PERC equivalent to those charged to other
municipalities.

5. WASTE HANDLING AGREEMENTS

    Certain of PERC's long-term, put-pay contracts with municipalities for
disposal of solid waste contain provisions which, at the date the bonds are
fully paid, allow the municipalities to purchase the facility or terminate or
extend the contracts.

    Certain of the long-term, put-pay contracts with municipalities contain
provisions which allow the municipalities to receive a portion of PERC's annual
cash flows, as defined.

                         FINANCIAL STATEMENT SCHEDULES

The Board of Directors
KTI, Inc.

We have audited the consolidated financial statements of KTI, Inc. as of
December 31, 1998 and 1997, and for each of the three years in the period ended
December 31, 1998, and have issued our report thereon dated March 30, 1999,
except for the second paragraph of Note 9 as to which the date is August 27,
1999, Note 2 as to which the date is August 30, 1999 and the first paragraph of
Note 21 as to which the date is September 23, 1999 (included elsewhere in this
Registration Statement). Our audits also included the financial statement
schedules listed in Item 21(b) of this Registration Statement. These schedules
are the responsibility of KTI's management. Our responsibility is to express an
opinion based on our audits.

In our opinion, the financial statement schedules referred to above, when
considered in relation to the basic financial statements taken as a whole,
present fairly in all material respects the information set forth therein.

As discussed in Note 2, the previously issued Schedule I--Condensed Financial
Information of KTI, Inc. for each of the three years in the period ended
December 31, 1998 has been restated to reflect the deferral of revenue related
to certain proceeds received in connection with the restructuring of a power
purchase agreement and the sale of electric generating capacity with two
utilities.

SCHEDULE I--CONDENSED FINANCIAL INFORMATION OF KTI, INC.--(CONTINUED)

1. BASIS OF PRESENTATION

    In the parent-company-only financial statements, KTI, Inc. (the "Company")
investment in subsidiaries is stated at cost plus equity in undistributed
earnings of subsidiaries since date of acquisition. Parent-company-only
financial statements should be read in conjunction with the Company's
consolidated financial statements

2. RESTATEMENT

    The Company's balance sheets as of December 31, 1998 and 1997 and the
related statements of operations, stockholders' equity and cash flows for each
of the three years in the period ended December 31, 1998 have been restated. The
restatement is a result of the Securities and Exchange Commission's review of
the Company's proxy materials related to the prospective merger with Casella
Waste Systems (See Note 5). The restatement relates to revenue recognized as a
result of the restructuring of a power purchase agreement and the sale of
electric generating capacity by two of the Company's majority-owned subsidiaries
with its customers, BHE and CMP, which were completed in 1998 and 1996,
respectively (See notes 4 and 5 to the consolidated financial statements). At
the time of these transactions, the Company had recognized revenues representing
a portion of the cash received in 1996 and the total consideration received in
1998. After discussions with the staff of the Securities and Exchange
Commission, the Company agreed to defer these amounts and recognize them over
the term of the respective power purchase and capacity purchase agreements to
comply with generally accepted accounting principles. The impact of the
restatement on the Company's consolidated financial results as originally
reported is summarized as follows:

    At December 31, 1998, the Company was in default of a debt covenant
contained in it's Revolving Credit Agreement and received a waiver from the bank
for this default. On May 12, 1999, the Company executed an amendment to the
Revolving Credit Agreement (the "Amended Agreement") modifying certain financial
covenants and requiring bank approval for all acquisitions. The Amended
Agreement requires that the Company and certain subsidiaries, as defined,
maintain certain specified financial covenants, including, a minimum interest
coverage ratio, a maximum funded debt to EBITDA ratio, a minimum fixed charge
coverage ratio, and a maximum debt to capitalization ratio, each as defined in
the Amended Agreement. The Company's ability to satisfy these covenants is
dependent on its ability to substantially achieve its operating plan. As of
June 30, 1999, the Company was in default

                                      S-5

3. DEBT (CONTINUED)
of certain of these covenants and received a waiver from the bank for this
default through January 1, 2000. See Note 9 to the consolidated financial
statements for additional discussion.

4. GUARANTEE

    As a result of a limited partnership interest in Penobscot Energy Recovery
Company ("PERC"), a majority-owned consolidated subsidiary, the Company had a
contingent obligation to make additional capital contributions to PERC of
approximately $3,710. The Company had an irrevocable letter of credit from a
bank securing this commitment. This contingent obligation expired during 1998.

    During 1998, certain bonds payable at the Company's majority-owned
consolidated subsidiary, Penobscot Energy Recovery Company ("PERC") were
refinanced. In conjunction with this refinancing, the Company issued a $3,000
limited guarantee of PERC's payment obligation under the refinanced bonds
payable in favor of the issuer and trustees of the bonds payable. See Note 9 to
the consolidated financial statements for additional discussion.

5. SUBSEQUENT EVENT

    On September 23, 1999, the Company entered into an amended Agreement and
Plan of Merger (the "Merger Agreement") with Casella Waste Systems, Inc.,
("Casella") a publicly-owned company engaged in the waste services industry.
This Merger Agreement was an amendment to the original agreement dated
January 12, 1999. The merger will be completed through the exchange of all of
shares of the Company's common stock for shares of Casella's Class A common
stock based on an exchange ratio specified in the Merger Agreement. In addition,
all of the Company's outstanding and unexercised stock options and stock
purchase warrants will be converted into similar rights to acquire Casella's
Class A common stock under the same terms and conditions and the same exchange
ratio. Subsequent to the completion of the merger, the current Casella
stockholders will own a majority of the combined company. Under the terms of the
Merger Agreement, Casella is required to file a registration statement with the
Securities and Exchange Commission to register the shares of its Class A common
stock to be issued in the Merger. The merger is subject to, among other things,
approval of the Company's and Casella's stockholders. No assurances can be given
that the remaining conditions of the Merger will be satisfied and that the
merger will be consummated. In connection with the merger, Casella has agreed to
reimburse the Company for its investment banking fees and other merger related
costs and as of December 31, 1998, approximately $1,160 of merger related costs
have been deferred.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

          (IN THOUSANDS OF DOLLARS EXCEPT SHARE AND PER SHARE AMOUNTS)

                                  (UNAUDITED)

                                 JUNE 30, 1999

1. BASIS OF PRESENTATION

    The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
only of normal recurring accruals) considered necessary for a fair presentation
have been included. The municipal solid waste ("MSW") market in Maine, which
provides material to the waste-to-energy segment, is seasonal, with one-third
more MSW generated in the summer months than is generated during the rest of the
year. The Residential and Commercial Recycling segments experience increased
volumes of newspaper in November and December due to increased newspaper
advertising and retail activity during the holiday season. Additionally, the
Residential Recycling segment operates facilities in Florida which experience
increased volumes of recyclable materials during the winter months followed by
decreases in the summer months in connection with seasonal changes in
population. Operating results for the three and six month periods ended
June 30, 1999 and 1998 are not necessarily indicative of the results that may be
expected for the full year. For further information, refer to the consolidated
financial statements and notes thereto included in the Company's annual report
on Form 10-K for the year ended December 31, 1998. Certain 1998 financial
information contained herein has been reclassified to conform with the 1999
presentation.

2. RESTATEMENT

    The Company's balance sheet as of June 30, 1999 and the related statements
of operations, stockholders' equity and cash flows for each of the three and six
month periods ended June 30, 1999 and 1998 have been restated. The restatement
is a result of the Securities Exchange Commission's review of the Company's
proxy materials related to the prospective merger with Casella Waste Systems
(See Note 3). The restatement relates to revenue recognized as a result of the
restructuring of a power purchase agreement and the sale of electric generating
capacity by two of the Company's majority-owned subsidiaries with it's
customers, BHE and CMP, which were completed in 1998 and 1996. At the time of
these transactions, the Company had recognized revenues representing a portion
of the cash received in 1996 and the total consideration received in 1998. After
discussions with the staff of the Securities and Exchange Commission, the
Company agreed to defer these amounts and recognize them over the term of the
respective power purchase and capacity purchase agreements to comply with
generally accepted accounting principles. In addition, performance credits
previously reported as expense have been reclassified as a reduction of
revenues. The impact of the restatement on the Company's consolidated financial
results as originally reported is summarized as follows:

3. MERGER AND ACQUISITIONS

    On September 23, 1999, KTI, Inc. (the "Company") entered into an Agreement
and Plan of Merger (the "Merger Agreement") with Casella Waste Systems, Inc.,
("Casella") a publicly-owned company engaged in the waste services industry. The
merger will be completed through the exchange of all of the shares of the
Company's common stock for shares of Casella's Class A common stock based on an
exchange ratio specified in the Amended Merger Agreement. In addition, all of
the Company's outstanding and unexercised stock options and stock purchase
warrants will be converted into similar rights to acquire Casella's Class A
common stock under the same terms and conditions and the same exchange ratio.
Subsequent to the completion of the merger the current Casella stockholders will
own a majority of the combined company. Under the terms of the Merger Agreement,
Casella is required to file a registration statement with the Securities and
Exchange Commission to register the shares of its Class A common stock to be
issued in the merger. The merger is subject to, among other things, approval of
the Company's and Casella's stockholders. No assurance can be given that the
conditions of the merger will be satisfied or that the merger will be
consummated. In connection with the merger, Casella has agreed to reimburse the
Company for its investment banking fees and other merger related costs and as of
June 30, 1999, approximately $1,482 of merger related costs have been deferred.

3. MERGER AND ACQUISITIONS (CONTINUED)
    On March 31, 1999 and May 19, 1999, pursuant to the Second Amended, Restated
and Extended Waste Disposal Agreement among PERC and the municipalities named
therein, the municipalities made capital contributions to Penobscot Energy
Recovery Company, Limited Partnership ("PERC"), which were recorded as
additional minority interest, totaling $730 and $240, respectively, in exchange
for 1.31% and 0.43%, respectively, of limited partnership interest in PERC.

    On January 27, 1999 the Company completed its acquisition of AFA
Group, Inc. and subsidiaries ("AFA"), an integrated wood waste processing and
hauling business located in Newark, New Jersey. Payment of the aggregate
purchase price, including all direct costs, of $9,682 consisted of (i) 460,000
shares of the Company's common stock valued at $20.70 per share (based on the
closing price of the common stock on the date of announcement) and (ii) $150 in
cash. This acquisition was accounted for as a purchase, and accordingly, the
assets and liabilities have been recorded at their estimated fair value at the
date of acquisition. The excess of the purchase price over the fair value of the
acquired net assets of $6,363 has been recorded as goodwill and is being
amortized on a straight-line basis over 30 years.

5. CONTINGENCIES

    The Company is a defendant in a consolidated purported class action, which
alleges violations of certain sections of the federal securities laws. The
Company believes the allegations are without merit and intends to defend the
litigation vigorously.

    Two lawsuits have been filed against a subsidiary of the Company alleging
fraud and tortious interference. The actions are based on two contracts between
the plaintiff and the subsidiary, which contracts require all disputes to be
resolved by arbitration. Arbitration proceedings have commenced. The Company
believes it has meritorious defenses to the allegations.

    The majority shareholder of a company acquired by a subsidiary of the
Company instigated arbitration proceedings against the Company and two of its
subsidiaries, alleging the subsidiaries acted to frustrate the "earn-out"
provisions of the acquisition agreement and thereby precluding him from
receiving, or alternatively, reducing the sum to which he was entitled to
receive. He also alleges his employment agreement was wrongfully terminated. The
claim for arbitration alleges direct charges in excess of $5,000 and requests
punitive damages, treble damages and attorneys fees. The Company and its
subsidiaries have responded to the demand, denying liability and filed a
counterclaim for $1,000 for misrepresentations. The Company believes it has
meritorious defenses to the claims.

    The Company is a defendant in certain lawsuits alleging various claims
incurred in the ordinary course of business.

    Management of the Company does not believe that the outcome of these
matters, individually or in the aggregate, will have a material effect on the
Company's financial condition, cash flows or results of operations.

7. IMPAIRMENT OF COMMERCIAL RECYCLING LONG-LIVED ASSETS

    On June 1, 1999, the Company completed the sale of its commercial recycling
facility located in Franklin Park, Illinois and recorded a loss of approximately
$444.

7. IMPAIRMENT OF COMMERCIAL RECYCLING LONG-LIVED ASSETS (CONTINUED)
    As a result of this loss and the continued poor operating performance of
this segment, the Company initiated an impairment review of the long-lived
assets, including goodwill, in the Commercial Recycling segment. A revised
operating plan for each of the remaining facilities in the Commercial Recycling
segment was developed. While revenues are stable, the Commercial Recycling
segment continues to operate at levels of profitability, which are significantly
below the levels anticipated when the acquisitions were completed. In addition,
with the continued consolidation of the solid waste industry and the continued
focus on the disposal aspects of this industry, the possibility of selling these
facilities for amounts approximating their carrying value is remote.

    The Company determined that the estimated future undiscounted cash flows for
the KTI Recycling of New Jersey ("Newark Plant") facility were below the
carrying value of the related equipment and leasehold improvements. The Company
adjusted the carrying value of the related equipment and leasehold improvements
of the Newark Plant by approximately $3,000 to their estimated fair value of
approximately $1,142. The fair value of the long-lived assets was based on the
expected cash flows discounted at a rate commensurate with the risk involved.

8. PLANT CONSOLIDATION, RESTRUCTURING AND OTHER UNUSUAL ITEMS

    In April 1999, FCR, Inc., a subsidiary of the Company, signed a new
agreement with a municipality to operate a material recovery facility in
Charlotte, North Carolina. As part of this agreement, the Company committed to
relocate the cellulose insulation plant located in Ronda, North Carolina to the
material recovery facility in Charlotte. This secures the supply of raw material
for the cellulose insulation plant and provides additional cost savings from the
integration of recycling and the manufacturing of cellulose insulation into one
facility. As a result, the Company developed an exit plan for the closing of the
plant in Ronda, North Carolina and began the construction of the new cellulose
insulation plant during the second quarter. The Company recorded a restructuring
charge of approximately $1,205, which consisted primarily of the write-down of
equipment and leasehold improvements and an accrual for the remaining payments
under the noncancelable lease of the Ronda facility, in the second quarter.

    During the second quarter, the Company reached agreement with an employee to
restructure the amounts paid under an employment contract. The Company recorded
a restructuring charge of approximately $320 relating to amounts due under the
revised contract.

    In June 1999, the Company initiated a plan to close the Residential
Recycling Segment's material recovery facility located in Howes Cave, New York
and process the materials from this facility at another Residential Recycling
Segment facility. The Company recorded a restructuring charge of $514, which
consisted primarily of the remaining payments under noncancelable leases of the
building and equipment, in the second quarter.

    Included in restructuring charges is $433 of deferred acquisition costs
related to acquisitions that were terminated during the second quarter.

8. PLANT CONSOLIDATION, RESTRUCTURING AND OTHER UNUSUAL ITEMS (CONTINUED)
    In April 1998, a subsidiary of the Company, FCR, Inc. ("FCR"), entered into
an amended agreement to operate a material recovery facility in Stratford,
Connecticut. This agreement requires FCR to add additional processing equipment
to this facility within a certain period of time as defined in the amended
agreement or pay the municipality $100 per year over the next five years. In
April 1999, FCR determined that this processing equipment was not cost effective
due to other alternative methods of processing and, thus, will not install the
equipment. As a result, the Company recorded the penalty included in the
agreement of $500 for the payments to be made to the municipality. The amount is
accrued and classified as other liabilities as of June 30, 1999.

    Other charges of $131 represents an accrual for penalties assessed by the
Florida Department of Environmental Protection related to the temperature of the
discharge water at the TERI Telogia Facility.

    In the first quarter of 1999, the Company recorded a $748 restructuring
charge. The restructuring initiatives primarily involve the Company's Commercial
Recycling segment and represent primarily severance and other costs related to
employee reductions. In connection with the restructuring, the Company
terminated ten employees. The restructuring charges relate to integration of the
brokerage operation acquired as part of the New Jersey Fibers acquisition and
elimination of costs as a result of streamlining the operations of acquisitions
completed in 1998. The Company recorded $374 against this reserve during 1999.

9. INCOME TAXES

    The income tax benefit was approximately $2,565 for the six months ended
June 30, 1999 compared to an income tax provision of approximately $614 during
the same period in 1998. During 1999, the effective tax rate utilized by the
Company of 30.4% represents the estimated annual effective rate based on the
total estimated pretax income of the Company for the year ended December 31,
1999. The effective rate in 1998 was 37.3% and the decrease in the effective
rate in 1999 is primarily due to an increase in nondeductible goodwill.

10. REVOLVING LINE OF CREDIT AGREEMENT

    On May 12, 1999, the Company's Revolving Line of Credit Agreement with a
bank (the "Credit Agreement") was amended (the "Amended Agreement") modifying
certain financial covenants and requiring bank approval for all acquisitions.
The Amended Agreement requires that the Company and certain subsidiaries, as
defined, maintain certain specified financial covenants, including, a minimum
interest coverage ratio, a maximum funded debt to EBITDA ratio, a minimum fixed
charge coverage ratio, and a maximum debt to capitalization ratio, each as
defined in the Amended Agreement. The Company recorded a charge of $835 in
connection with the amendment. This charge was recorded in interest expense
during the second quarter.

    As of June 30, 1999, the Company was in default of the financial covenants
of its $150.0 million line of credit. The Company's lender has waived the
violation of the financial covenants through

10. REVOLVING LINE OF CREDIT AGREEMENT (CONTINUED)
January 1, 2000. As a result, the outstanding amount under the line of credit
has been classified as a current liability. Upon the consummation of the merger,
this line of credit will be replaced by the credit facility of the merged
company. However, no assurances can be given that the conditions of the merger
will be satisfied or that the merger will be consummated.

    The Company will continue to select interest rates on the outstanding
borrowings based on the bank's prime rate or LIBOR rates, however, the interest
rates range from the bank's prime rate to the bank's prime rate plus 1.50% or
LIBOR plus 1.88% to LIBOR plus 3.25% depending on the attainment of a financial
covenant, as defined, in the Amended Agreement.

    As of June 30, 1999, one of the Company's subsidiaries was in violation of
one of the financial covenants of its revolving line of credit. Borrowings under
this line of credit are classified as a current liability at June 30, 1999. Upon
consummation of the merger, this line of credit will be replaced by the credit
facility of the merged company.

                           DECEMBER 31, 1997 AND 1996

1. DESCRIPTION OF THE BUSINESS AND ACCOUNTING POLICIES:

DESCRIPTION OF BUSINESS

    FCR, Inc. (the Company), through its subsidiaries, is a diversified
recycling company engaged in residential recycling and the manufacturing of
products using recycled materials. The Company consists of three business
segments: Recycling Division, Insulation Division and Plastics Division.

    The Recycling Division is engaged in the design and operations of facilities
which sort, process, and market recyclable materials delivered to the facilities
either by municipalities under long-term contracts as part of their overall
recycling programs or contract haulers under various commercial recycling
programs. The Recycling Division operates facilities in Connecticut, New Jersey,
Virginia, North Carolina, South Carolina, Florida and Tennessee. The Recycling
Division sells primarily recyclable material to entities who manufacture
recycled-paper or containers, constructed from newspaper, corrugated cardboard,
aluminum, plastic or glass. Recyclable materials are considered commodities and
are subject to fluctuations beyond contractual price agreements. The Recycling
Division represented 61% of the Company's 1997 consolidated net revenues.

    The Insulation Division began in May 1997 with the purchase of Suncoast
(Note 2). The Insulation Division produces cellulose insulation which is
primarily used in the construction of manufactured and single family residential
homes. The primary raw material for cellulose insulation is newspaper collected
from residential recycling programs. The cellulose insulation is sold to the
manufacturers of manufactured homes and insulation contractors throughout the
United States and thus the results of the Insulation Division are impacted by
the sales of new homes which is cyclical in nature. The Insulation Division
operates facilities in North Carolina, Florida, Arizona, Oregon and Ohio. Sales
of cellulose insulation represented 31% of the Company's 1997 consolidated net
revenues.

    The Plastics Division began in September 1997 with the purchase of Resource
Recycling, Inc. (Note 2). The Plastics Division is a reprocessor of high density
polyethylene (HDPE) plastics collected from residential recycling programs and
industrial customers. The plastics are ground, washed and repellatized. The
recycled plastics are sold primarily to manufacturers of nursery supplies and
packaging materials for household and automotive products. The Plastics Division
operates three facilities in North Carolina. Sales of recycled plastics
represented 8% of the Company's 1997 consolidated net revenues. The majority of
the Plastics Division's raw materials are obtained from the Recycling Division.

    In November 1996, the Company discontinued the operations of the commercial
office recycling line of business (Note 12).

ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

    The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated.

    REVENUE RECOGNITION

    Revenue from tipping fees is recognized upon delivery of the recyclable
materials to the Company. Revenue from the sale of recyclable materials,
insulation and plastic is recognized upon shipment. The

                           DECEMBER 31, 1997 AND 1996

1. DESCRIPTION OF THE BUSINESS AND ACCOUNTING POLICIES: (CONTINUED)
Recycling Division shares a portion of its revenue from the sale of recyclable
materials with certain of those municipalities it serves.

    COMMODITY CONTRACTS

    The Company engages in long-term contracts with various customers to sell
recyclable materials at a negotiated price in relationship to market price with
a contractual floor. These contracts range in term from one to nine years and
expire at various dates through 2006.

    CASH EQUIVALENTS

    The Company considers unrestricted interest-bearing deposits with financial
institutions with original maturities of three months or less to be cash
equivalents.

    ACCOUNTS RECEIVABLE AND CONCENTRATION OF CREDIT RISK

    The Company extends credit based on an evaluation of customers' financial
condition, generally without requiring collateral. Exposure to losses on
receivables is principally dependent on each customer's financial condition. The
Company monitors its exposure for credit losses by providing allowances for
anticipated losses.

    At December 31, 1997 and 1996, the Company's accounts receivable balance
represents amounts due primarily from purchasers of recyclable materials,
insulation, plastic and fees from municipalities, net of an allowance for
doubtful accounts of approximately $253,000 and $30,000 at December 31, 1997 and
1996, respectively.

    INVENTORIES

    Inventories are valued at the lower of cost or market, with cost being
determined on the basis of the first-in, first-out (FIFO) method. Inventories
consist of the following at December 31, 1997 and 1996:

</TABLE>

    PROPERTY AND EQUIPMENT

    Property and equipment are recorded at cost. Depreciation has been computed
using the straight-line method over the estimated lives of the various asset
groups as follows: building--10 years; machinery and equipment--3 to 10 years;
and office furniture and fixtures--3 to 7 years. Leasehold improvements are
amortized over the lesser of the life of the lease or the estimated useful life
of the improvement.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                           DECEMBER 31, 1997 AND 1996

1. DESCRIPTION OF THE BUSINESS AND ACCOUNTING POLICIES: (CONTINUED)
    GOODWILL

    Goodwill is the excess of the cost of net assets acquired in business
combinations over their fair value. Goodwill of $8,232,000 is being amortized on
a straight-line basis over 40 years. The accumulated amortization of intangible
assets is approximately $111,000 as of December 31, 1997.

    The Company continually evaluates whether events and circumstances have
occurred that indicate the remaining estimated useful life of goodwill may
warrant revision or that the remaining balance of goodwill may not be
recoverable. When factors indicate that goodwill should be evaluated for
possible impairment, the Company uses an estimate of the undiscounted net cash
flows of the related businesses over the remaining life of the goodwill in
measuring whether the goodwill is recoverable.

    LOAN ACQUISITION COSTS

    The Company amortizes loan acquisition costs over the term of the related
loan agreements. As of December 31, 1997 and 1996, loan acquisition costs of
$541,000 and $38,000, respectively, were included in other assets.

    DEFERRED INCOME TAXES

    Deferred tax assets and liabilities reflect the impact of temporary
differences between the financial reporting basis and the tax basis of assets
and liabilities. Such amounts are recorded using presently enacted tax rates and
regulations.

    LONG-TERM CONTRACT COSTS

    The Company defers certain direct incremental costs to secure successful
long-term contracts with municipalities for the design and operation of
materials recovery facilities. These costs for successful efforts are amortized
over the life of the contract which range from three to ten years. During 1997
and 1996, the Company incurred approximately $60,000 and $57,000, respectively,
of direct incremental long-term contract costs and approximately $286,000 and
$288,000, respectively, are deferred at December 31, 1997 and 1996.

    FAIR VALUE OF FINANCIAL INSTRUMENTS

    The carrying amounts of cash and cash equivalents, accounts receivable,
accounts payable and accrued liabilities are reflected in approximate fair value
because of the short-term maturity of these financial instruments. The carrying
amount of long-term debt approximates fair value at December 31, 1997 and 1996.

    MANAGEMENT ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions. These affect the reported amounts of assets and liabilities,
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

    RECLASSIFICATIONS

    Certain balances in the accompanying prior years consolidated financial

2. ACQUISITIONS:

SUNCOAST MFG. CO.

    On May 7, 1997, the Company acquired all of the outstanding shares of common
stock of Suncoast Insulation MFG. Co., N.C. and Suncoast MFG. Co., N.C.
(collectively, Suncoast). Suncoast is a manufacturer of cellulose insulation and
other related products. The acquisition has been accounted for as a purchase and
the results of the operations of Suncoast have been included in the consolidated
financial statements since the date of acquisition. The excess of the purchase
price over the fair value of the net assets acquired was approximately
$6,708,000 and has been recorded as goodwill, which will be amortized on a
straight-line basis over 40 years. The aggregate purchase price for the stock
acquired was approximately $10,013,000 which is comprised of cash and shares of
the Company's common stock.

    During the next two years, the former shareholder of Suncoast may receive up
to $2,000,000 of additional consideration. The amount of the additional
consideration will be based on the earnings of Suncoast for the 12 months ended
April 30, 1998 and 1999, as defined in the purchase agreement. Of this amount,
$924,000 was advanced at closing and is recorded as a note receivable from the
former shareholder. Upon reaching the earnings targets discussed above, this
amount will be reclassified to goodwill. If earned, the remaining additional
consideration will be in the form of cash, note payable to the former
shareholder, or the Company's common stock and the form of the additional
consideration is at the election of both the Company and the former shareholder.
Any additional consideration will be recorded as an addition to goodwill.

    In conjunction with the purchase of Suncoast, the Company and the former
shareholder of Suncoast entered into an employment agreement through
April 2004. In addition, the former shareholder signed a noncompete agreement
commencing on the date of acquisition and continuing for five years after the
former shareholder's termination from the Company. The Company has an additional
$370,000 note receivable from this shareholder.

purchase price for the assets acquired was $4,100,000 which is comprised of cash
and the assumption of certain liabilities.

    On March 31, 1999, the former shareholders of Resource may receive
additional consideration. The amount of the additional consideration will be
based on the earnings of Resource for the 12 months ending March 31, 1999, as
defined in the purchase agreement. If earned, the remaining additional
consideration will be in the form of stock and will be recorded as goodwill.

USF INSULATION

    On December 1, 1997, the Company acquired all of the outstanding shares of
stock of USF Insulation, Inc. and T.J. Miller Research and Technology, Inc.
(collectively, USF). USF is a manufacturer of cellulose insulation and other
related products. The acquisition has been accounted for as a purchase and the
results of the operations of USF have been included in the consolidated
financial statements since the date of acquisition. The excess of the purchase
paid price over the fair value of the net assets acquired was approximately
$1,524,000 and has been recorded as goodwill, which will be amortized on a
straight-line basis over 40 years. The aggregate purchase price for the stock
acquired was approximately $2,700,000 which is comprised of a note payable to
the former owner and shares of the Company's common stock. The note payable to
shareholder owner was paid in full on January 5, 1998, and has been included in
current liabilities as of December 31, 1997.

    In conjunction with the acquisition of USF, the Company and former
shareholder of USF entered into a consulting agreement through November 1999. In
addition, the former shareholder of USF signed a noncompete agreement commencing
on the date of acquisition and continuing for five years after termination of
the consulting agreement.

    In 1997, the Company entered into two new term loan agreements with a bank.
Under the term loan A agreement, the Company borrowed $12,000,000 to refinance
its existing term debt and finance the acquisition of Suncoast, Resource and
USF. The term loan A agreement requires quarterly payments of $400,000 to
$700,000, plus interest, through December 31, 2000, with the remaining
outstanding principal due at maturity on March 31, 2001. The term loan B
commences on December 31, 1998, with the conversion of all outstanding
borrowings under the B revolving credit agreement (see discussion below). Under
the term loan B agreement, principal payments which begin on March 31, 1999,
will be based on a six-year amortization with quarterly payments of principal
and interest through December 31, 2000, with the remaining outstanding principal
due on March 31, 2001. The interest rates for both term loans are based on prime
rates that range from prime to prime plus 1.50% depending on the performance of
the Company.

revolving line of credit that related to the purchase of new equipment was
refinanced and is classified as long-term debt in the accompanying consolidated
balance sheet and as borrowings under revolving loan B in the table above. These
borrowings will convert to the term loan B at December 31, 1998.

LINES OF CREDIT

    In 1997, the Company entered into two new revolving line-of-credit
agreements with a bank. The A revolving line of credit (A Revolver) agreement
provides the Company loans or letters of credit of up to $5,000,000. Amounts may
be borrowed on a revolving basis and are limited to 85% of eligible receivables,
as defined. The A Revolver expires on March 31, 2001. At December 31, 1997, the

3. LONG-TERM DEBT AND LINES OF CREDIT: (CONTINUED)
Company had approximately $1,802,000 outstanding on the A Revolver. In addition,
the Company had $535,000 in outstanding letters of credit as security for
performance on long-term contracts with municipalities which reduced the
availability under the A Revolver. Under the B revolving line-of-credit (B
Revolver) agreement the Company may borrow up to $3,000,000. Borrowings under
this agreement are limited to 80% of the cost of new equipment, as defined. On
December 31, 1998, the outstanding portion of the B revolving credit agreement
converts to the term loan B. There were no borrowings on the B Revolver at
December 31, 1997. The Company may select interest rates for both revolving
line-of-credit agreements based on prime or LIBOR rates. The interest rates
range from prime to prime plus 1.25% or LIBOR plus 125 basis points to LIBOR
plus 300 basis points depending on the performance of the Company. The interest
rate on the line of credit outstanding at December 31, 1997, was 8.75%. A fee of
 .25% per annum is charged on the unused portions of these revolving credit
agreements.

    The revolving line-of-credit agreements and the term loan agreements contain
covenants, which among other things, require the maintenance of certain
financial ratios. The credit agreements also limit the maximum amount of
indebtedness and requires lender approval for certain significant mergers and
acquisitions, dividends and asset sales, as defined in the loan agreement.
Borrowings under the revolving credit and term loan agreements are secured by
substantially all assets of the Company.

4. SUBORDINATED DEBENTURES:

    Concurrent with the Suncoast acquisition discussed above, the Company
completed a private placement of $6,000,000 in subordinated debentures which
were used to finance the acquisition of Suncoast. The subordinated debentures
have a maturity date of April 1, 2001, and interest at 14.25% is paid quarterly.

    The purchasers of the subordinated debentures were also issued warrants to
purchase 227,044 shares of the Company's common stock at $.01 per share. These
warrants were valued at $90,000 at May 7, 1997, and are included as a part of
additional paid-in capital as of December 31, 1997. Beginning on May 7, 2005, at
the election of the purchasers of the subordinated debentures, the Company is
required to repurchase the warrants (Put Agreement) at a price determined by a
formula that is defined in the subordinated debenture agreements. This formula
is based on the results of operations in the year ending December 31, 2004. The
Company has accreted approximately $26,000 of interest expense in relation to
the Put Agreement with a corresponding increase in additional paid-in capital.

    The subordinated debenture agreements contain covenants, which among other
things, require the maintenance of certain financial ratios similar to the
Company's senior debt agreements. These agreements also limit the maximum amount
of indebtedness and requires lender approval for certain significant mergers and
acquisitions, dividends and asset sales, as defined in the debenture agreement.

5. CAPITAL AND OPERATING LEASES:

    The Company leases certain facilities under operating leases with various
terms expiring through 2003. Certain of these facilities are leased from certain

10. COMMITMENTS AND CONTINGENCIES:

    The Company may be subject to lawsuits, tax examinations or other claims
arising out of the normal course of business. While the ultimate result of any
unasserted claim cannot be determined, management does not expect that the
disposition of any such matters would have a material adverse effect on the
financial position or results of operations of the Company.

    On October 1, 1997, the Company was engaged to procure the design of and be
responsible for the construction of a recycling facility. The Company has
subcontracted most of the construction of the facility which is estimated to be
completed during 1998. The total contract price is approximately $2,800,000.
Income from this contract is recognized using the percentage of completion
method. As of December 31, 1997, the contract is approximately 7% complete.

    When current estimates indicate that a loss will result from a contract,
provision is made for the entire amount of the estimated loss. Revisions to
estimates are reflected in the period in which the events giving rise to the
revision become known.

</TABLE>

12. DISCONTINUED OPERATIONS:

    In November 1996, the Company developed a plan to discontinue the operations
of the commercial office recycling line of business as a result of the decline
in demand for high grade scrap paper during 1996 and a refocusing of the
Company's resources on its residential recycling operations. The operations of
this line of business consisted of three facilities located in Atlanta, Georgia;
Alexandria, Virginia; and Stratford, Connecticut. The operations of the
commercial office recycling line of business have been accounted for as
discontinued operations. In 1996, the Company provided for estimated losses on
disposal of the discontinued operations of approximately $118,000 which included
a provision for anticipated operating losses prior to disposal and an estimated
loss on the disposal. The actual losses incurred during the phase-out period and
the actual cost of disposal approximated the estimates established during 1996.
No additional amounts relating to discontinued operations were recorded in 1997.

13. SUBSEQUENT EVENTS:

ACQUISITION OF RESOURCE RECOVERY SYSTEMS, INC.

    On July 1, 1998, FCR acquired all the outstanding shares of stock of
Resource Recovery System, Inc. (RRS). RRS provides residential and commercial
recycling processing and marketing services with plants located in Berlin,
Connecticut, Howes Cave, New York, Claverack, New York, Saginaw, Michigan, Ann
Arbor, Michigan, Athens, Georgia and Sarasota, Florida. The aggregate purchase
price for the stock of approximately $4,409,000 was paid in cash. In connection
with this transaction, certain debt of RRS totaling approximately $3,960,000 was
refinanced under FCR's existing credit agreement and approximately $2,131,000 of
debt of RRS remained outstanding. In addition, two former shareholders of RRS
signed a five year covenant-not-to-compete for $500,000. The acquisition was
financed with a $10,000,000 term note with LaSalle National Bank.

13. SUBSEQUENT EVENTS: (CONTINUED)
MERGER WITH KTI, INC.

    On August 28, 1998, the Company was merged (the Merger) with and into KTI
Acquisition Sub, Inc. (Merger Sub), a wholly owned subsidiary of KTI, Inc.
(KTI), pursuant to an agreement and Plan of Merger, dated July 22, 1998, (the
Merger Agreement), by and among KTI, Merger Sub, the Company and the
securityholders of the Company. Pursuant to the Merger Agreement, at the closing
of the Merger, the securities of the Company held by the securityholders of the
Company were converted into the right to receive an aggregate of
(i) $30,000,000 in cash, (ii) 1,714,285 shares of no par value common stock of
KTI and (iii) an additional payment of up to $30,000,000 based upon the earnings
from the operation of the Company for the period from July 1, 1998, through
December 31, 1998, payable in a combination of cash and common stock of KTI. As
a result of the Merger, the Company became a wholly owned subsidiary of KTI.

14. OTHER CONTINGENCIES

    The former majority shareholder of Resource instigated arbitration
proceedings against the Company, alleging the Company acted to frustrate the
"earn-out" provisions of the acquisition agreement and thereby precluding him
from receiving, or alternatively, reducing the sum to which he was entitled to
receive. He also alleges his employment agreement was wrongfully terminated. The
claim for arbitration alleges direct charges in excess of $5,000,000 and
requests punitive damages, treble damages and attorneys fees. The Company and
its subsidiaries have responded to the demand, denying liability and filed a
counterclaim for $1,000,000 for misrepresentations. The Company believes it has
meritorious defenses to the claims.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders and Board of Directors of Casella Waste Systems, Inc.:

    We have audited the accompanying consolidated balance sheets of Casella
Waste Systems, Inc. (a Delaware corporation) and subsidiaries as of April 30,
1998 and 1999, and the related consolidated statements of operations, redeemable
preferred stock, redeemable put warrants and stockholders' equity (deficit) and
cash flows for each of the three years in the period ended April 30, 1999. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Casella Waste Systems, Inc.
and subsidiaries as of April 30, 1998 and 1999, and the results of their
operations and their cash flows for each of the three years in the period ended
April 30, 1999, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION

    Casella Waste Systems, Inc. (the Company or Casella), a Delaware
corporation, is a regional, integrated, non-hazardous solid waste services
company that provides collection, transfer, disposal and recycling services in
Vermont, New Hampshire, Maine, upstate New York, northern Pennsylvania and
Massachusetts.

    As of June 18, 1999, the Company owned and/or operated five subtitle D
landfills, two landfills permitted to accept construction and demolition
materials, 51 transfer stations, 16 recycling processing facilities, and 41
solid and liquid waste collection divisions, which collectively serve over
500,000 commercial, industrial and residential customers.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    A summary of the Company's significant accounting policies follows:

    (A) PRINCIPLES OF CONSOLIDATION

    The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries. All significant intercompany transactions and
balances have been eliminated in consolidation.

    (B) USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes and the disclosure of contingent assets and liabilities.
Actual results could differ from those estimates.

    (C) REVENUE RECOGNITION

    The Company recognizes revenues as the services are provided. Certain
customers are billed in advance and, accordingly, recognition of the related
revenues is deferred until the services are provided.

    (D) FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist primarily of cash and cash
equivalents, trade receivables, investments in closure trust funds, trade
payables and debt instruments. The book values of cash and cash equivalents,
trade receivables, investments in closure trust funds and trade payables
approximate their respective fair values. The Company's debt instruments that
are outstanding as of April 30, 1999 have carrying values that approximate their
respective fair values. See Note 4 for the terms and carrying values of the
Company's various debt instruments.

    (E) CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments purchased with
maturities of three months or less to be cash equivalents.

    (F) CLOSURE FUND ESCROW

    Restricted funds held in trust consist of amounts on deposit with various
banks that support the Company's financial assurance obligations for its
facilities' closure and postclosure costs.

    (G) PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, less accumulated depreciation and
amortization. The Company provides for depreciation using the straight-line
method by charges to operations in amounts that allocate the cost of the assets
over their estimated useful lives as follows:

<TABLE>
<CAPTION>
                                                               ESTIMATED
ASSET CLASSIFICATION                                          USEFUL LIFE
- --------------------                                          -----------
<S>                                                           <C>
Buildings and improvements..................................  10-35 years
Machinery and equipment.....................................   2-15 years
Rolling stock...............................................   1-12 years
Containers..................................................   2-12 years
</TABLE>

    The cost of maintenance and repairs is charged to operations as incurred.
Depreciation expense for the years ended April 30, 1997, 1998 and 1999 was
$8,604,000, $12,195,000 and $14,208,000 respectively.

    Capitalized landfill costs include expenditures for land and related
airspace, permitting costs and preparation costs. Landfill permitting and
preparation costs represent only direct costs related to these activities,
including legal, engineering and construction. Interest is capitalized on
landfill permitting and construction projects and other projects under
development while the assets are undergoing activities to ready them for their
intended use. The interest capitalization rate is based on the Company's
weighted average cost of indebtedness. Interest capitalized for the years ended
April 30, 1997, 1998 and 1999 was $182,000, $136,000 and $530,000 respectively.
Management routinely reviews its investment in operating landfills, transfer
stations and other significant facilities to determine whether the costs of
these investments are realizable.

    Landfill permitting, acquisition and preparation costs, excluding the
estimated residual value of land, are amortized as permitted airspace of the
landfill is consumed. Landfill preparation costs include the costs of
construction associated with excavation, liners, site berms and the installation
of leak detection and leachate collection systems. In determining the
amortization rate for these landfills, preparation costs include the total
estimated costs to complete construction of the landfills' permitted and
probable to be permitted capacity. Units-of-production amortization rates are
determined annually for each of the Company's operating landfills. The rates are
based on estimates provided by the Company's engineers and accounting personnel
and consider the information provided by surveys which are performed at least
annually.

    (H) ACCRUED CLOSURE AND POSTCLOSURE COSTS

    Accrued closure and postclosure costs include the current and noncurrent
portion of accruals associated with obligations for closure and postclosure of
the Company's operating and closed landfills. The Company, based on input from
its engineers and accounting personnel, estimates its future cost requirements
for closure and postclosure monitoring and maintenance for solid waste landfills
based on its interpretation of the technical standards of the U.S. Environmental
Protection Agency's Subtitle D regulations and the air emissions standards under
the Clean Air Act as they are being applied on a state-by-state basis. Closure
and postclosure monitoring and maintenance costs represent the costs related to
cash expenditures yet to be incurred when a landfill facility ceases to accept
waste and closes.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Accruals for closure and postclosure monitoring and maintenance requirements
in the U.S. consider final capping of the site, site inspection, groundwater
monitoring, leachate management, methane gas control and recovery, and operation
and maintenance costs to be incurred during the period after the facility
closes. Certain of these environmental costs, principally capping and methane
gas control costs, are also incurred during the operating life of the site in
accordance with the landfill operation requirements of Subtitle D and the air
emissions standards. Reviews of the future cost requirements for closure and
postclosure monitoring and maintenance for the Company's operating landfills by
the Company's engineers and accounting personnel are performed at least annually
and are the basis upon which the Company's estimates of these future costs and
the related accrual rates are revised. The Company provides accruals for these
estimated costs as the remaining permitted airspace of such facilities is
consumed.

    The states in which the Company operates require a certain portion of these
accrued closure and postclosure obligations to be funded at any point in time.
Accordingly, the Company has placed $4,170,000 and $5,459,000 at April 30, 1998
and 1999, respectively, in restricted investment accounts to fund these future
obligations.

    In addition, the Company has been required to post a surety bond or bank
letter of credit to secure its obligations to close its landfills in accordance
with environmental regulations. At April 30, 1999, the Company had provided one
letter of credit totaling $1,307,000, expiring on April 15, 2000, to secure the
Company's landfill closure obligations.

    (I) INTANGIBLE ASSETS

    Intangible assets at April 30, 1998 and 1999 consist of the following (in
thousands):

</TABLE>

    Goodwill is the cost in excess of fair value of identifiable assets of
acquired businesses and is amortized using the straight-line method over periods
not exceeding 40 years. Covenants not to compete and customer lists are
amortized using the straight-line method over their estimated useful lives,
typically no more than 10 years.

    Deferred debt acquisition costs are capitalized and amortized over the life
of the related debt using the effective interest method.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    (J) IMPAIRMENT OF LONG-LIVED ASSETS

    In accordance with SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets To Be Disposed Of," the Company
evaluates the recoverability of its carrying value of the Company's long-lived
assets and certain intangible assets when events and circumstances have occurred
that indicate potential impairment of such assets. The assessment is based on
estimated undiscounted cash flows to be generated from each asset as compared to
its carrying value. To the extent impairment is identified, the Company reduces
the carrying value of such impaired assets to their fair market value.

    The Casella T.I.R.E.S. plant in Eliot, Maine was established by purchasing
the waste tire processing assets of the Seaward companies in June, 1996. The
ongoing profitability of this location is dependent on a continuing secondary
market for the product of its tire shredding operations, primarily as tire
derived fuel (TDF). Due to pressures on the Company's TDF customers to meet
requirements of the Clean Air Act, management projects that over the next few
years these customers will replace TDF with natural gas as a fuel, and that the
future undiscounted cash flows will be less than the current carrying value of
the assets associated with this site.

    The primary assets associated with this site include real estate, tire
processing and other equipment, and goodwill. The Company recognized a $971,000
non-cash pre-tax charge related to the impairment of these assets during fiscal
1998. The impairment charge was computed as the difference between the
April 30, 1998 carrying value of the affected assets, and their fair market
value as of that date. The fair market value of the affected assets is computed
in accordance with SFAS No. 121 as the discounted projected future net cash
inflows.

    In addition, during fiscal 1998, Waste Stream recognized a $600,000 non-cash
pretax charge related to the impairment of certain assets located at its
Grasslands facility. The impairment charge was computed as the difference
between the April 30, 1998 carrying value of the affected assets, and the fair
value at that time. Generally, fair value represents the Company's discounted
projected future cash inflows from the use of the asset or group of assets.

    (K) INCOME TAXES

    The Company records income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes". Under SFAS No. 109, deferred income taxes are
recognized based on the expected future tax consequences of differences between
the financial statement basis and the tax basis of assets and liabilities,
calculated using currently enacted tax rates.

    (L) EARNINGS PER SHARE

    During 1997, the Company adopted the provisions of SFAS No. 128 "Earnings
Per Share" and retroactively restated all prior periods in accordance with SFAS
No. 128. In accordance with SFAS No. 128, basic earnings per share is computed
by dividing net income (loss) by the weighted average number of shares of Common
Stock outstanding during the year. The computation of diluted earnings per share
is similar to the computation of basic earnings per share, except that the
denominator is increased for the assumed exercise of dilutive options using the
treasury stock method and other

</TABLE>

    Potentially dilutive shares are excluded from diluted shares outstanding for
the years ended April 30, 1997 and 1998 because their impact is anti-dilutive.
The number of potentially dilutive shares excluded from the earnings per share
calculation was 4,480,000 and 3,045,000 for the years ended April 30, 1997 and
1998, respectively. Additionally, for the year ended April 30, 1999, options to
purchase 211,000 common shares were excluded from the calculation of potentially
dilutive shares because their impact was antidilutive.

    (M) RECENT ACCOUNTING PRONOUNCEMENTS

    In 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income". Statement 130 establishes standards for
reporting and presentation of comprehensive income and its components.
Comprehensive income is defined as the change in equity of a business enterprise
during a period from transactions and other events and circumstances from
non-owner sources and includes all changes in equity during a period except
those resulting from investments by owners and distributions to owners. The
Company adopted Statement 130 effective May 1, 1998 and there was no effect on
the Company's financial statements upon adoption.

    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities". SFAS No. 133
establishes accounting and reporting standards requiring that every derivative
instrument (including certain derivative instruments embedded in other
contracts) be recorded in the balance sheet as either an asset or liability
measured at its fair value. SFAS No. 133 requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. SFAS No. 133 is effective for fiscal years
beginning after June 15, 2000. A company may also implement SFAS No. 133 as of
the beginning of any fiscal quarter after issuance (that is, fiscal quarters
beginning June 16, 1998 and thereafter). The Company does not believe this
statement will have a material impact on the consolidated balance sheet or
statement of operations.

</TABLE>

    All of the pooled entities had fiscal year ends of December 31 and,
subsequent to the poolings, changed their year ends to conform with that of the
Company. For the calendar quarter ended March 31, 1997, $480,524 in revenues and
$47,034 in net income were excluded from results of operations in order to
conform the accounting period of the pooled companies with that of the Company.
For the month ended January 31, 1998 $717,767 in revenues and $66,485 in net
income were excluded from results of operations. For the month ended
January 31, 1999 $312,752 in revenues and $20,674 in net loss were excluded from
results of operations. Retained earnings was increased by $47,034 and $66,485 in
the fiscal years ended April 30, 1997 and 1998 respectively and decreased by
$20,674 during the year ended April 30, 1999 in order to effect these changes.
Cash flows resulting from the periods excluded from results of operation
discussed above are immaterial and have been included in the Statement of Cash
Flows.

3. BUSINESS COMBINATIONS (CONTINUED)
    On September 4, 1998 the Company completed its merger with Hakes C & D
Disposal, Inc. (Hakes) in a business combination recorded as a pooling of
interests. The Company issued 67,617 shares of its class A common stock for all
of the outstanding stock of Hakes. This transaction has been accounted for as an
immaterial pooling. Accordingly, retained earnings has been adjusted to reflect
the accumulated deficit of Hakes on the acquisition date, and prior periods have
not been restated.

    (B) TRANSACTIONS RECORDED AS PURCHASES

    During fiscal 1997, the Company completed 25 acquisitions, including the
25-year capital lease of a landfill. During fiscal 1998, the Company acquired 33
solid waste hauling operations, exclusive of the All Cycle merger accounted for
as a pooling of interests. During fiscal 1999, the Company acquired 50 solid
waste hauling operations, exclusive of the pooling transactions discussed above.
These transactions were accounted for as purchases. Accordingly, the operating
results of these businesses are included in the Consolidated Statements of
Operations from the dates of acquisition, and the purchase prices have been
allocated to the net assets acquired based on fair values at the dates of
acquisition with the residual amounts allocated to goodwill.

    The purchase prices allocated to the net assets acquired were as follows (in
thousands):

    On January 21, 1998 the Company entered into a three-year interest rate swap
agreement (the Swap Agreement) with a bank. The purpose was to effectively
convert a portion of the Company's interest rate exposure on advances under its
revolving credit facility from a floating rate to a fixed rate until the
expiration of the Swap Agreement. The Swap Agreement effectively fixes the
Company's interest rate on the notional amount of $45,000,000 to 5.8% per annum.
Net monthly payments or monthly receipts under the Swap Agreement are recorded
as adjustments to interest expense. The Company paid $163,000 and $174,000 under
this agreement during the years ended April 30, 1998 and 1999, respectively. The
fair market value of the the Company's interest rate swap, based on the
estimated termination value at April 30, 1998 and 1999 was $1.1 million and $0.7
million, respectively. In the event of nonperformance by the counterparty, the
Company would be exposed to interest rate risk on the entire amount outstanding.

    The revolving credit facility contains certain covenants that, among other
things, restrict dividends or stock repurchases, limit capital expenditures and
annual operating lease payments, and set minimum

    (B) LEGAL PROCEEDINGS

    In the normal course of its business and as a result of the extensive
governmental regulation of the waste industry, the Company may periodically
become subject to various judicial and administrative proceedings involving
Federal, state or local agencies. In these proceedings, an agency may seek to
impose fines on the Company or to revoke, or to deny renewal of, an operating
permit held by the Company. In addition, the Company may become party to various
claims and suits pending for alleged damages to persons and property, alleged
violation of certain laws and for alleged liabilities arising out of matters
occurring during the normal operation of the waste management business. However,
there is no current proceeding or litigation involving the Company that it
believes will have a material adverse effect upon the Company's business,
financial condition and results of operations.

    (C) ENVIRONMENTAL LIABILITY

    The Company is subject to liability for any environmental damage, including
personal injury and property damage, that its solid waste facilities may cause
to neighboring property owners, particularly as a result of the contamination of
drinking water sources or soil, possibly including damage resulting from
conditions existing before the Company acquired the facilities. The Company may
also be subject to liability for similar claims arising from off-site
environmental contamination caused by pollutants or hazardous substances if the
Company or its predecessors arrange to transport, treat or dispose of those
materials. Any substantial liability incurred by the Company arising from
environmental damage could have a material adverse effect on the Company's
business, financial condition and results of operations. The Company is not
presently aware of any situations that may have a material adverse impact.

    (D) SAWYER LANDFILL ROYALTY PAYMENTS

    In connection with an acquisition, the Company agreed to pay to the seller a
royalty for certain additional permitted landfill capacity. The royalty due is
equal to $2.50 per ton for the first 400,280 tons of such additional capacity
and $3.50 per ton thereafter. The payments are generally due as the landfill is
utilized except that at the time of the successful permitting, the first 51
million of royalties becomes immediately due and payable. This amount may be
taken in cash or stock or an equivalent per share price of $6.55. This option is
at the election of the seller and is only available for the first royalty
payment.

    As of April 30, 1999, all permits required for expansion of the site have
been obtained from the appropriate State of Maine authorities. The required
permits and licenses have not been obtained from the Town of Hampden, Maine.
Therefore, the initial Royalty Payment is not due as of April 30, 1999.

6. STOCKHOLDERS' EQUITY

    (A) PUBLIC OFFERINGS

    In November 1997, the Company completed an initial public offering of
3,000,000 shares of its Class A Common Stock (the "IPO") for proceeds of
42,428,000, net of underwriters discount and offering expenses. In accordance
with the terms of the Company's agreements: (i) the Series A and Series B
Redeemable Preferred Stock with warrants exercisable for Class A Common Stock
(Series A and Series B, respectively) were automatically redeemed and the
redemption price was applied to the exercise price of the warrants; (ii) the
Series D Convertible Preferred Stock (Series D) was converted

automatically into shares of Class A Common Stock; and (iii) the Series C
Mandatorily Redeemable Preferred Stock (Series C) was redeemed at its stated
redemption price of $7.00 per share.

between the carrying value and the redemption value using the effective interest
method through the earliest redemption date for the Series A, B, C and D
Preferred Stock.

    In July 1998 the Company completed a public offering of 2,060,587 shares of
its Class A Common Stock at $27.25 per share. In addition, as part of this same
offering, 1,470,580 shares of the Company's Class A Common Stock were sold by
certain selling shareholders at $27.25 per share. The Company's proceeds of the
offering, net of underwriter's discount and issuance costs were $52,232,000.

    (B) PREFERRED STOCK

    The Company is authorized, with stockholder approval, to issue up to
1,000,000 shares of preferred stock in one or more series. As of April 30, 1999
and 1998, respectively, no shares of Preferred Stock are outstanding.

    (C) COMMON STOCK

    The holders of the Class A Common Stock are entitled to one vote for each
share held. The holders of the Class B Common Stock are entitled to ten votes
for each share held, except for the election of one director, who is elected by
the holders of the Class A Common Stock exclusively. The Class B Common Stock is
convertible into Class A Common Stock on a share-for-share basis at the option
of the shareholder.

    (D) STOCK WARRANTS

    At April 30, 1999, the Company had issued and outstanding warrants to
purchase 100,300 shares of the Company's Class A Common Stock at exercise prices
between $0.01 and $7.25 per share, based on the fair market value of the
underlying common stock at the time of the warrants' issuance. The warrants
become exercisable upon vesting and notification and expire between July 1998
and October 2003.

    (E) PUT WARRANTS

    In connection with an acquisition in April 1995, the Company issued 100,000
warrants to purchase one share each of Class A Common Stock exercisable at $6.00
per share. These warrants were putable to the Company at $4.00 per share or
callable by the Company at $7.00 per share beginning in April 1997 and were
initially recorded at their put price. These warrants were stated at their put
price per share in the accompanying balance sheet as of April 30, 1998. During
fiscal 1998 (but prior to the IPO), warrants to acquire 25,000 shares of
Class A Common Stock for cash proceeds of $150,000 were exercised. During the
same period the Company called the remaining 75,000 warrants in exchange for
total cash consideration of $525,000. The difference between the put price and
the call price was accreted through a charge to accumulated deficit at the time
of the call.

    During fiscal 1996, the FASB issued SFAS No. 123, "Accounting for
Stock-Based Compensation", which defines a fair value based method of accounting
for stock-based employee compensation and encourages all entities to adopt that
method of accounting for all of their employee stock compensation plans.
However, it also allows an entity to continue to measure compensation costs for
those plans using the intrinsic method of accounting prescribed by APB Opinion
No. 25. Entities electing to remain with the accounting in APB Opinion No. 25
must make pro forma disclosures of net income and earnings per share as if the
fair value based method of accounting defined in SFAS No. 123 had been applied.

6. STOCKHOLDERS' EQUITY (CONTINUED)
    The Company has elected to account for its stock-based compensation plans
under APB Opinion No. 25. However, the Company has computed, for pro forma
disclosure purposes, the value of all options granted during the years ended
April 30, 1997, 1998 and 1999 using the Black-Scholes option pricing model as
prescribed by SFAS No. 123, using the following weighted average assumptions for
grants in the years ended April 30, 1997, 1998 and 1999.

</TABLE>

    The total value of options granted during the years ended April 30, 1997,
1998 and 1999 would be amortized on a pro forma basis over the vesting period of
the options. Options generally vest over a one to three year period. Because the
method of accounting prescribed by SFAS No. 123 has not been applied to options
granted prior to May 1, 1995, the resulting pro forma compensation costs may not
be representative of that to be expected in future years. If the Company had
accounted for these plans in accordance with SFAS No. 123, the Company's net
income (loss) and net income (loss) per share would have decreased (increased)
as reflected in the following pro forma amounts (in thousands, except for per
share amounts):

</TABLE>

    All of the pooled entities had fiscal year ends of December 31 and,

Company.

    TRANSACTIONS RECORDED AS PURCHASES

    During the three months ended July 31, 1999, the Company acquired 11 solid
and liquid waste hauling operations in transactions accounted for as purchases.
These transactions were in exchange for consideration of approximately $1.7
million in cash to sellers. The operating results of these businesses are
included in the Consolidated Statement of Operations from the dates of
acquisition. The purchase prices have been allocated to the net assets acquired
based on fair values at the dates of acquisition with the residual amounts
allocated to goodwill.

    The following unaudited pro forma combined information (rounded to thousands
except for per share data) shows the results of the Company's operations as
though each of the completed acquisitions had occurred as of May 1, 1998:

cost savings or incremental costs that may occur as a result of the integration
and consolidation of the completed acquisitions.

2.  COMMITMENTS AND CONTINGENCIES

    In the normal course of business and as a result of the extensive
governmental regulation of the waste industry, the Company may periodically
become subject to various judicial and administrative proceedings involving
Federal, state or local agencies in the normal course of its business. In these
proceedings, an agency may seek to impose fines on the Company or to revoke, or
to deny renewal of, an operating permit held by the Company. In addition, the
Company may become party to various claims and suits pending for alleged damages
to persons and property, alleged violation of certain laws and for alleged
liabilities arising out of matters occurring during the normal operation of the
waste management business. However, there is no current proceeding or litigation
involving the Company that it believes will have a material adverse effect upon
the Company's business, financial condition and results of operations.

3.  ENVIRONMENTAL LIABILITIES

    The continuing business in which the Company is engaged is intrinsically
connected with the protection of the environment. As such, a significant portion
of the Company's operating costs and capital expenditures could be characterized
as costs of environmental protection. While the Company is faced, in the normal
course of business, with the need to expend funds for environmental protection
and remediation, it does not expect such expenditures to have a material adverse
effect on its financial condition or results of operations because its business
is based upon compliance with environmental laws and regulations and its
services are priced accordingly. In addition, as part of its ongoing operations,
the Company provides for estimated closure and post-closure monitoring costs
over the life of disposal sites as airspace is consumed. While all these costs
may increase in the future as a result of legislation or regulation, the Company
believes that in general it tends to benefit when government regulation
increases, since this may increase the demand for its services. Furthermore, the
Company believes it has the resources and experience to manage environmental
risk.

4.  EARNINGS PER SHARE

    In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 128, "Earnings Per Share" which
supercedes Accounting Principal Board opinion No. 15 and establishes new
accounting standards for the presentation of earnings per share. Primary EPS is
replaced by Basic EPS, which is computed by dividing income available to common
stockholders by the weighted average number of common shares outstanding for the
period. Fully Diluted EPS is replaced with Diluted EPS, which gives effect to
all common shares that would have been outstanding if all dilutive potential
common shares (relating to such things as the exercise of stock warrants and
convertible preferred stock) had been issued. The treasury stock method used to
compute the number of potentially-dilutive shares that would be repurchased with
the proceeds of potential stock issuances has been changed. The treasury stock
method now requires use of the average share price for the period instead of the
greater of the ending share price or the average share price.

their impact was anti-dilutive.

5.  SEGMENT REPORTING

    In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information" ("Statement 131"). Statement 131 establishes
standards for reporting information about operating segments in financial
statements. In general, Statement 131 requires that business entities report
selected information about operating segments in a manner consistent with that
used for internal management reporting.

    The Company classifies its operations into three geographical regions:
Eastern, Central and Western. The Company's revenues are derived mainly from one
industry segment, which includes the collection, transfer, recycling and
disposal of non-hazardous solid waste. Any other activities in which the Company
is engaged are not material to the total results of operations of the Company;
these activities are reflected in with the geographic reporting structure
outlined above.

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

    OVERVIEW

    The Company is a regional, integrated solid waste services company that
provides collection, transfer, disposal and recycling services in Vermont, New
Hampshire, Maine, Massachusetts, upstate New York and northern Pennsylvania. The
Company's objective is to continue to grow by expanding its services in markets
where it can be one of the largest and most profitable fully-integrated solid
waste services companies.

    On January 12, 1999 the Company signed a definitive merger agreement with
KTI, a publicly traded solid waste handling company operating in 21 states
throughout the United States. KTI specializes in solid waste disposal and
recycling, and operates manufacturing facilities utilizing recycled materials.
The Company believes the merger will give it additional growth opportunities in
its existing and adjacent markets, and the ability to enter new markets, as well
as achieve operational efficiencies as a result of the combination. On
September 9, 1999, the Company announced that it and KTI had revised and amended
the terms of the merger agreement. Pursuant to the amended merger agreement,
each share of KTI common stock will be exchanged for 0.51 shares of the
Company's class A common stock. The companies anticipate that the merger should
close during the fourth calendar quarter of 1999. Total merger transactional
costs deferred on the balance sheet (under the asset section as a deferred cost)
related to the KTI merger were $4.7 million through 7/31/99. Total estimated
merger costs are approximately $26 to $28 million dollars. All of these merger
costs will be expensed upon the consummation of the Pooling Transaction.

    The Company's revenues have increased from $45.1 million for the three
months ended July 31, 1998 to $55.0 million for the three months ended July 31,
1999. From May 1, 1998 through April 30, 1999, the Company acquired 55 solid
waste collection, transfer and disposal operations. Between May 1, 1999 and
July 31, 1999, the Company acquired an additional 13 such businesses. All but
two of these acquisitions were accounted for under the purchase method of
accounting for business combinations. Under the rules of purchase accounting,
the acquired companies' revenues and results of operations have been included
together with those of Casella Waste Systems, Inc. from the actual dates of the
acquisitions and will materially affect the period-to-period comparisons of the
Company's historical results of operations.

    This Quarterly Report and other reports, proxy statements, and other
communications to stockholders, as well as oral statements by the Company's
officers or its agents, may contain forward-looking statements within the
meaning of Section 27A of the Securities Act, with respect to, among other
things, the Company's future revenues, operating income, or earnings per share.
Without limiting the foregoing, any statements contained in this Quarterly
Report that are not statements of historical fact may be deemed to be
forward-looking statements, and the words "believes", "anticipates", "plans",
"expects", and similar expressions are intended to identify forward-looking
statements. There are a number of factors of which the Company is aware that may
cause the Company's actual results to vary materially from those forecast or
projected in any such forward-looking statement, certain of which are beyond the
Company's control. These factors include, without limitation, those outlined
below in the section entitled "Certain Factors That May Affect Future Results'.

successfully address any of these factors could have a material adverse effect
on the Company's results of operations.

    GENERAL

    The Company's revenues are attributable primarily to fees charged to
customers for solid and liquid waste collection, landfill, transfer and
recycling services. The Company derives a substantial portion of its collection
revenues from commercial, industrial and municipal services that are generally
performed under service agreements or pursuant to contracts with municipalities.
The majority of the Company's residential collection services are performed on a
subscription basis with individual households. Landfill and transfer customers
are charged a tipping fee on a per ton basis for disposing of their solid waste
at the Company's disposal facilities and transfer stations. The majority of the
Company's landfill and transfer customers are under one-year to ten-year
disposal contracts, with most having clauses for annual cost of living
increases. Recycling revenues consist of revenues from the sale of recyclable
commodities and from the sale of tire derived fuel. Other revenues consist
primarily of revenue from septic/liquid waste operations and other sources. The
Company's revenues are shown net of intercompany eliminations. The Company
typically establishes its intercompany transfer pricing based upon prevailing
market rates.

    The table below shows, for the periods indicated, the percentage of the
Company's revenues attributable to services provided. The decrease in the
Company's collection revenues as a percentage of revenues and the increase of
the Company's landfill revenues as a percentage of revenues in the current
fiscal year is primarily attributable to the impact of the Company's acquisition
of Hyland Landfill during the first quarter fiscal 1999 plus the increased
utilization of our North Country Landfill in Bethlehem, New Hampshire during the
first quarter of fiscal 2000. The increase in transfer revenues as a percentage
of revenues in the current fiscal year is mainly due to the acquisition of
transfer station operations in the prior fiscal year. The increase in recycling
revenues is due primarily to increased volumes with additional increased prices
received from the sale of recycled commodities. The increase in liquid waste and
other revenues as a percentage of revenues in the current fiscal year is
primarily due to the impact of acquisitions of septic/liquid waste operations
since the first quarter of fiscal 1999.

host community fees and royalties. Landfill operating expenses also include a
provision for closure and post-closure expenditures anticipated to be incurred
in the future, and leachate treatment and disposal costs.

    General and administrative expenses include management, clerical and
administrative compensation and overhead, professional services and costs
associated with the Company's marketing and sales force and community relations
expense.

    Depreciation and amortization expense includes depreciation of fixed assets
over the estimated useful life of the assets using the straight line method,
amortization of landfill airspace assets under the units-of-production method,
and the amortization of goodwill and other intangible assets using the straight
line method. The amount of landfill amortization expense related to airspace
consumption can vary materially from landfill to landfill depending upon the
purchase price and landfill site and cell development costs. The Company
depreciates all fixed and intangible assets, excluding non-depreciable land,
down to a $0 net book value, and does not apply a salvage value to any of its
fixed assets.

    Certain direct landfill development costs, such as engineering, permitting,
legal, construction and other costs directly associated with expansion of
existing landfills, are capitalized by the Company. Additionally, the Company
also capitalizes certain third party expenditures related to pending
acquisitions, such as legal and engineering. The Company will have material
financial obligations relating to closure and post-closure costs of its existing
landfills and any disposal facilities which it may own or operate in the future.
The Company has provided and will in the future provide accruals for future
financial obligations relating to closure and post-closure costs of its
landfills (generally for a term of 30 years after final closure of a landfill)
based on engineering estimates of consumption of permitted landfill airspace
over the useful life of any such landfill. There can be no assurance that the
Company's financial obligations for closure or post-closure costs will not
exceed the amount accrued and reserved or amounts otherwise receivable pursuant
to trust funds. The Company routinely evaluates all such capitalized costs, and
expenses those costs related to projects not likely to be successful. Internal
and indirect landfill development and acquisition costs, such as executive and
corporate overhead, public relations and other corporate services, are expensed
as incurred.

*   See discussion and computation of EBITDA below

    REVENUES.  Revenues increased $10.0 million, or 22.1%, to $55.0 million in
the quarter ended July 31, 1999 from $45.1 in the quarter ended July 31, 1998.
Of this increase, $5.7 million of the growth was due to the impact of businesses
acquired during fiscal year 1999 and during the first quarter of the current
fiscal year. The balance of the increase was due to internal volume and price
growth.

    COST OF OPERATIONS.  Cost of operations increased approximately $3.6
million, or 13.2%, to $30.9 million in the quarter ended July 31, 1999 from
$27.3 million in the same quarter of the prior fiscal year. Cost of operations
as a percentage of revenues decreased to 56.2% in the quarter ended July 31,
1999 from 60.6% in the same quarter of the prior fiscal year. The decrease was
primarily the result of: (i) productivity improvements in the Company's
collection operations as a result of better route density from acquisitions,
routing efficiencies through route audits and front-end loader vehicle
conversions completed throughout fiscal 1999; and (ii) margin improvements
because of price increases in fiscal 1999 and the first quarter of fiscal year
2000.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
approximately $1.4 million, or 21.9%, to $7.8 million in the quarter ended
January 31, 1999 from $6.4 million in the same quarter of the prior fiscal year.
General and Administrative expenses as a percentage of revenues have remained
approximately level in the periods under discussion.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense
increased $1.7 million, or 29.3%, to $7.6 million in the quarter ended July 31,
1999 from $5.9 million in the same quarter of the prior fiscal year.
Depreciation and amortization as a percentage of revenues increased to 13.9% in
the quarter ended July 31, 1999 from 13.1% in the same quarter of the prior
fiscal year. The increase in

                                  (UNAUDITED)

5.  SEGMENT REPORTING (CONTINUED)
depreciation and amortization is due to the increased concentration of revenues
in landfill activities, which typically have higher depreciation and
amortization charges relative to revenues compared to hauling revenues.

    MERGER COSTS.  The merger related costs of $1.5 million recorded in the
quarter ended July 31, 1999 were incurred in association with the Resource Waste
Systems, Inc. and Corning Community Disposal, Inc. mergers accounted for as
poolings of interests. The transactions are discussed above under 'Notes to
Consolidated Financial Statements'.

    INTEREST EXPENSE, NET.  Net interest expense decreased approximately $0.3
million, or 15.3% to $1.6 million in the quarter ended July 31, 1999 from $1.9
million in the same quarter of the prior fiscal year. This decrease primarily
reflects the reduction of the outstanding balance under the Company's
acquisition line of credit and other notes payable from the proceeds of the
Company's public stock offering in July, 1998.

    OTHER (INCOME) EXPENSE, NET.  Net other (income) expense has not
historically been material to the Company's results of operations.

    PROVISION FOR INCOME TAXES.  Provision for income taxes increased
approximately $0.9 million to $2.6 million in the quarter ended July 31, 1999
from $1.7 million in the same quarter of the prior fiscal year. This increase
reflects the Company's increase in profits in the quarter ended July 31, 1999
over the same quarter in the prior fiscal year. The combined effective tax rate
used by the Company in recording taxes for interim periods has been increased
from 44.1% in the quarter ended July 31, 1998 to 46.0% in the same quarter of
the current fiscal year. This increase reflects the non-deductible merger
expenses incurred during the quarter ended July 31, 1999.

    LIQUIDITY AND CAPITAL RESOURCES

    The Company's business is capital intensive. The Company's capital
requirements include acquisitions, fixed asset purchases and capital
expenditures for landfill development, cell construction, and site and cell
closure. The Company had positive net working capital of $3.3 million at
April 30, 1999 and positive net working capital of $9.5 million at July 31,
1999.

    The Company has a $150 million revolving line of credit with a group of
banks for which BankBoston, N.A. is acting as agent. This line of credit is
secured by all assets of the Company, including the Company's interest in the
equity securities of its subsidiaries. This revolving line of credit matures in
January, 2003. Funds available to the Company under this line of credit were
$54.3 million at July 31, 1999. In connection with the proposed merger with KTI,
the Company will be required to replace its existing credit facility. The
Company is currently negotiating a new credit facility with a number of banks.

    Net cash provided by operating activities was $9.2 million for the three
months ended July 31, 1999 compared to $13.3 million for the same period of the
prior fiscal year. The decrease was primarily due to the decrease in accounts
payable and the increase in accounts receivable due to the extensive growth,
partially offset by the increase in the Company's net income for the three
months ended

July 31, 1999 over the prior fiscal year, increased depreciation and
amortization and increased closure/ post closure accruals.

    Cash used in investing activities decreased $0.2 million from $19.8 million
to $19.6 million in the three months ended July 31, 1999 over the same period of
the prior fiscal year. The decrease in investing activities reflects fewer
acquisitions for the quarter ended July 31, 1999 accounted for as purchases,
offset by capital expenditures. The Company's cash needs to fund investing
activities are expected to increase further as the Company continues to complete
acquisitions, and continues to expend capital in order to service internal
growth.

    Net cash provided by financing activities was $11.3 million in the three
months ended July 31, 1999 compared to $7.2 million for the same period of the
prior year. The net cash provided by financing activities in the current fiscal
year reflects the borrowings on the Company's credit facility, offset by
repayments. Net cash provided by financing activities in the comparable period
of the prior year reflects the net proceeds of the follow-on offering and
borrowings on the Company's credit facility, offset by repayments.

    SEASONALITY

    The Company's revenues have historically been lower during the months of
November through March. This seasonality reflects the lower volume of waste
during the late fall, winter and early spring months primarily because: (i) the
volume of waste relating to construction and demolition activities decreases
substantially during the winter months in the northeastern United States; and
(ii) decreased tourism in Vermont, Maine and eastern New York during the winter
months tends to lower the volume of waste generated by commercial and restaurant
customers, which is partially offset by the winter ski industry. Since certain
of the Company's operating and fixed costs remain constant throughout the fiscal
year, operating income results are therefore impacted by a similar seasonality.
addition, particularly harsh weather conditions could result in increased
operating costs to certain of the Company's operations.

    The Company's quarterly revenues and operating results have varied
significantly in the past and are likely to vary substantially from quarter to
quarter in the future. The Company establishes its expenditure levels based on
its expectations as to future revenues, and, if revenue levels are below
expectations, expenses can be disproportionately high. Due to a variety of
factors including general economic conditions, governmental regulatory action,
acquisitions, capital expenditures and other costs related to the expansion of
operations and services and pricing changes, it is possible that in some future
quarter, the Company's operating results will be below the expectations of
public market analysts and investors. In such events, the Company's Class A
Common Stock price would likely be materially and adversely affected.

    INFLATION AND PREVAILING ECONOMIC CONDITIONS

    To date, inflation has not had a significant impact on the Company's
operations. Consistent with industry practice, most of the Company's contracts
provide for a pass through of certain costs, including increases in landfill
tipping fees and, in some cases, fuel costs. The Company therefore believes it
should be able to implement price increases sufficient to offset most cost
increases resulting from

5.  SEGMENT REPORTING (CONTINUED)
inflation. However, competitive factors may require the Company to absorb at
least a portion of these cost increases, particularly during periods of high
inflation.

    The Company's business is located in the northeastern United States.
Therefore, the Company's business, financial condition and results of operations
are susceptible to downturns in the general economy in this geographic region
and other factors affecting the region such as state regulations and severe
weather conditions. The Company is unable to forecast or determine the timing
and/or the future impact of a sustained economic slowdown.

    YEAR 2000 ISSUES

    The approach of the year 2000 has raised concerns about the ability of
information technology systems and non-information technology systems, primarily
computer software programs, to properly recognize and process date-sensitive
information with respect to the Year 2000.

    The Company has undertaken a Year 2000 project, comprised of four phases, to
address these concerns. Phase one, which has been completed, consisted of
awareness, Year 2000 planning, preparing a written plan, management approval and
support. Phase two involved the evaluation of all systems and equipment,
including hardware, software, security and voice mail, with respect to Year 2000
compliance. The completion date for phase two was June 30, 1999. Phase three
involved addressing any deficiencies identified in Phase two. The completion
date for Phase three was July 31, 1999. Phase four involves the validation and
testing of all systems and equipment, and the anticipated completion date is
September 30, 1999. Casella has performed, and continues to perform routine
updates of all software and hardware systems to facilitate Year 2000 compliance.

    The Company has completed numerous acquisitions in recent months, and the
information systems of a limited number of these acquired operations have not
yet been fully integrated with Casella's information systems. This integration
of the completed acquisitions is expected to occur by October 31, 1999. Casella
continues to make acquisitions as an integral component of its growth strategy.
There is no assurance that the information systems of all acquired operations,
particularly those acquisitions completed in the latter portion of calendar
1999, will be Year 2000 compliant by December 31, 1999.

    Casella uses well-regarded nationally known software vendors for both its
general accounting applications and industry-specific customer information and
billing systems, and all internal productivity software. Casella has been
informed by the respective vendors that all application software is fully Year
2000 compliant.

    Casella's banking arrangement is with an international banking institution
which has informed Casella that it is taking all necessary steps to insure its
customers uninterrupted service throughout applicable Year 2000 time frames.
Casella's payroll is out-sourced by the largest provider of third-party payroll
services in the country, which has made a commitment of uninterrupted service to
their customers throughout applicable Year 2000 time

    Casella is currently in the process of replacing all older personal
computers and servers. There are two servers and 25 additional personal
computers that will be replaced, 16 of which will be for the weight-measurement
systems. The two servers were replaced during the first quarter of fiscal 2000
(ending July 31, 1999). Casella has acquired a Year 2000 compliant
weight-measurement system. Currently two beta sites are operational and Casella
is in the process of defining the implementation

plan for the remaining sites. During the implementation, all non Year 2000
compliant hardware will be replaced.

    Casella currently plans a final testing of all systems in the second quarter
of fiscal 2000 (ending October 31, 1999) and expects to be fully Year 2000
compliant by the end of that fiscal quarter.

    Casella has expended approximately $1.5 million dollars over the last
eighteen months to address hardware and software-related Year 2000 compliance
issues, principally through the implementation of a new frame network system. A
portion of this investment is attributable to integrating information systems of
companies that the Company has acquired. Casella will use funds from current
operations or Casella's line of credit to meet Year 2000 remediation expenses.

    No single customer represents more than one percent of Casella's revenues,
and we do not expect any material adverse effect on Casella's revenues in the
event an individual customer experiences Year 2000 problems.

    In addition, Casella does not believe the Year 2000 noncompliance of the
Company's suppliers of goods and services, other than as specifically discussed
above, would have a material adverse effect on Casella's revenues and results of
operations. Accordingly, Casella's has not sought assurances of Year 2000
compliance from these other vendors.

    Casella expects to begin its evaluation of its most reasonably likely worst
case scenarios with respect to the Year 2000 in the third calendar quarter of
1999. Based upon the results of that evaluation Casella may develop an
appropriate contingency plan.

    EBITDA

    EBITDA represents operating income (earnings before interest and taxes, or
"EBIT") plus depreciation and amortization expense. EBITDA is not a measure of
financial performance under generally accepted accounting principles, but is
provided because the Company understands that certain investors use this
information when analyzing the financial position and performance of the
Company.

    CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

    The following important factors, among others, could cause actual results to
differ materially from those indicated by forward-looking statements made in
this Quarterly Report and presented elsewhere by management from time to time.

    The Company is party to an Agreement and Plan of Merger with KTI, Inc. There
can be no assurance that the merger will take place on the anticipated
timetable, if at all, or if it does, that it will

                                     F-127

5.  SEGMENT REPORTING (CONTINUED)
result in the synergies and other benefits anticipated by the two companies. The
benefits of the merger could be impacted by KTI's operating results, which have
been below expectations in recent quarters.

    In connection with the merger with KTI, the Company will be required to
replace its existing credit facility. Although the Company is in the process of
negotiating a new credit facility, there can be no assurance that it will obtain
such a credit facility in the amount, or on the timetable, sought by the
Company. In the event that it is unable to obtain a sufficient credit facility,
the Company's acquisition program, results of operations and financial condition
could be materially and adversely affected. If the Company were unable to obtain
a new credit facility, it will be unable to repay its existing credit facility
and will be in default.

    The Company's objective is to continue to grow by expanding its services in
markets where it can be one of the largest and most profitable fully-integrated
solid waste services companies. Such growth, if it were to occur, could place a
significant strain on the Company's management and operational, financial and
other resources.

    The Company has incurred net losses in the past. There can be no assurance
that the Company will be profitable in the future.

    The Company's strategy envisions that a substantial part of the Company's
future growth will come from making acquisitions consistent with its strategy.
There can be no assurance that the Company will be able to identify suitable
acquisition candidates and, once identified, to negotiate successfully their
acquisition at a price or on terms and conditions favorable to the Company, or
to integrate the operations of such acquired businesses with the Company.
Certain of these acquisitions may be of significant size and may include assets
that are outside the Company's geographic territories or are ancillary to the
Company's core business strategy.

    The Company is highly dependent upon the services of the members of its
senior management team, the loss of any of whom may have a material adverse
effect on the Company's business, financial condition and results of operations.
In addition, the Company's future success depends on its continuing ability to
identify, hire, train, motivate and retain highly trained personnel.

    The Company anticipates that any future business acquisitions will be
financed through cash from operations, borrowings under its bank line of credit,
the issuance of shares of the Company's Class A Common Stock and/or seller
financing. There can be no assurance that the Company will have sufficient
existing capital resources or will be able to raise sufficient additional
capital resources on terms satisfactory to the Company, if at all, in order to
meet its capital requirements.

    The Company's operating program depends on its ability to operate and expand
the landfills it owns and leases and to develop new landfill sites. Several of
the Company's landfills are subject to local laws purporting to regulate their
expansion and other aspects of their operations. There can be no assurance that
the laws adopted by municipalities in which the Company's landfills are located
will not have a material adverse effect on the Company's utilization of its
landfills or that the Company will be successful in obtaining new landfill sites
or expanding the permitted capacity of any of its current landfills once its
remaining disposal capacity has been consumed.

    The Company may be adversely affected by changes in the commodity pricing of
recycled materials.

                          AGREEMENT AND PLAN OF MERGER

    AGREEMENT AND PLAN OF MERGER (the "Agreement"), dated as of January 12,
1999, by and among Casella Waste Systems, Inc., a Delaware corporation
("Buyer"), Rutland Acquisition Sub, Inc., a New Jersey corporation and a direct,
wholly-owned subsidiary of Buyer ("Sub"), and KTI, Inc., a New Jersey
corporation ("Seller").

    WHEREAS, the Boards of Directors of Buyer and Seller deem it advisable and
in the best interests of each corporation and its respective stockholders that
Buyer and Seller combine in order to advance the long-term business interests of
Buyer and Seller;

    WHEREAS, the combination of Buyer and Seller shall be effected by the terms
of this Agreement and in accordance with the New Jersey Business Corporation Act
(the "NJBCA") through a merger of Sub into Seller, as a result of which the
stockholders of Seller will become stockholders of Buyer (the "Merger");

    WHEREAS, concurrently with the execution of this Agreement, and as a
condition and inducement of the willingness of Buyer to enter into this
Agreement, Seller will execute a Stock Option Agreement in favor of Buyer in the
form attached hereto as Exhibit A (the "Seller Stock Option Agreement");

    WHEREAS, concurrently with the execution of this Agreement, and as a
condition and inducement of the willingness of each of Buyer and Seller to enter
into this Agreement, certain affiliates of each of Buyer and Seller will execute
Voting Agreements in the form attached hereto as Exhibits B-1 and B-2,
respectively (the "Seller Voting Agreements" and the "Buyer Voting Agreements");

    WHEREAS, for Federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code"); and

    WHEREAS, for accounting purposes, it is intended that the Merger shall be
accounted for as a pooling of interests.

    NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth below, the
parties agree as follows:

                                   ARTICLE I
                                   THE MERGER

    SECTION 1.01 EFFECTIVE TIME OF THE MERGER.  Subject to the provisions of
this Agreement, a certificate of merger in such form as is required by the
relevant provisions of the NJBCA (the "Certificate of Merger") shall be duly
executed and acknowledged by the Surviving Corporation (as defined below) and
thereafter delivered to the Treasurer of the State of New Jersey for filing, as
soon as practicable on the Closing Date (as defined in Section 1.02). The Merger
shall become effective upon the filing of the Certificate of Merger with the
Treasurer of the State of New Jersey (the "Effective Time").

    SECTION 1.02 CLOSING.  The closing of the Merger (the "Closing") will take
place at 10:00 a.m., E.S.T., on a date to be specified by Buyer and Seller (the
"Closing Date"), which shall be no later than the second business day after
satisfaction or waiver of the conditions set forth in Article VII, at the
offices of Hale and Dorr LLP, 60 State Street, Boston, Massachusetts, unless
another date, place or time is agreed to in writing by Buyer and Seller.

    SECTION 1.03 EFFECTS OF THE MERGER.  At the Effective Time (i) the separate
existence of Sub shall cease and Sub shall be merged with and into Seller (Sub
and Seller are sometimes referred to below as the "Constituent Corporations" and
Seller following the Merger is sometimes referred to below as the "Surviving
Corporation"), (ii) the Certificate of Incorporation of Seller shall be amended
so that Article Three of such Certificate of Incorporation reads in its entirety
as follows: "The total number of
<PAGE>
shares of all classes of stock which the Corporation shall have authority to
issue is 1,000, all of which shall consist of Common Stock, $.01 par value per
share", and, as so amended, such Certificate of Incorporation shall be the
Certificate of Incorporation of the Surviving Corporation, and (iii) the Bylaws
of Sub as in effect immediately prior to the Effective Time shall be the Bylaws
of the Surviving Corporation. The Merger shall have the effects set forth in
Section 14 A: 10-6 of the NJBCA.

    SECTION 1.04 DIRECTORS AND OFFICERS.  The directors and officers of Sub
immediately prior to the Effective Time shall become the directors and officers
of the Surviving Corporation, each to hold office in accordance with the
Certificate of Incorporation and Bylaws of the Surviving Corporation. Martin
Sergi will also be a director and an officer of the Surviving Corporation.

                                   ARTICLE II
                            CONVERSION OF SECURITIES

    SECTION 2.01 CONVERSION OF CAPITAL STOCK.  As of the Effective Time, by
virtue of the Merger and without any action on the part of the holder of any
shares of the common stock, no par value per share, of Seller ("Seller Common
Stock"), or capital stock of Sub:

        (a) Capital Stock of Sub. Each issued and outstanding share of the
    capital stock of Sub shall be converted into and become one fully paid and
    nonassessable share of common stock of the Surviving Corporation.

        (b) Cancellation of Treasury Stock and Buyer-Owned Stock. All shares of
    Seller Common Stock that are owned by Seller as treasury stock and any
    shares of Seller Common Stock owned by Buyer, Sub or any other wholly-owned
    Subsidiary (as defined in Section 3.01) of Buyer shall be cancelled and
    retired and shall cease to exist and no stock of Buyer or other
    consideration shall be delivered in exchange therefor. All shares of
    Class A Common Stock, $.01 par value per share, of Buyer ("Buyer Common
    Stock") owned by Seller shall be unaffected by the Merger.

        (c) Exchange Ratio for Seller Common Stock. Subject to Section 2.02,
    each issued and outstanding share of Seller Common Stock (other than shares
    to be cancelled in accordance with Section 2.01(b) and any shares of Seller
    Common Stock which are held by shareholders who are dissenting shareholders
    pursuant to Section 14 A: 11-3 of the NJBCA), shall be converted into the
    right to receive .91 shares (the "Exchange Ratio") of Buyer Common Stock.
    All such shares of Seller Common Stock when so converted, shall no longer be
    outstanding and shall automatically be cancelled and retired and shall cease
    to exist, and each holder of a certificate representing any such shares
    shall cease to have any rights with respect thereto, except the right to
    receive the shares of Buyer Common Stock and any cash in lieu of fractional
    shares of Buyer Common Stock to be issued or paid in consideration therefor
    upon the surrender of such certificate in accordance with Section 2.02,
    without interest.

        (d) Adjustments to Exchange Ratio. The Exchange Ratio shall be adjusted
    to reflect fully the effect of any stock split, reverse split, stock
    dividend (including any dividend or distribution of securities convertible
    into Buyer Common Stock or Seller Common Stock), reorganization,
    recapitalization or other like change with respect to Buyer Common Stock or
    Seller Common Stock occurring after the date hereof and prior to the
    Effective Time.

    SECTION 2.02 EXCHANGE OF CERTIFICATES.  The procedures for exchanging
outstanding shares of Seller Common Stock for Buyer Common Stock pursuant to the
Merger are as follows:

        (a) Exchange Agent. As of the Effective Time, Buyer shall deposit with a
    bank or trust company designated by Buyer and Seller (the "Exchange Agent"),
    for the benefit of the holders of shares of Seller Common Stock, for
    exchange in accordance with this Section 2.02, through the Exchange Agent,
    (i) certificates representing the shares of Buyer Common Stock (such shares
    of

                                      A-2
<PAGE>
    Buyer Common Stock, together with cash in lieu of fractional shares and any
    dividends or distributions with respect thereto, being hereinafter referred
    to as the "Exchange Fund") issuable pursuant to Section 2.01 in exchange for
    outstanding shares of Seller Common Stock, and (ii) cash in an amount
    sufficient to make payments of cash in lieu of fractional shares, if any,
    required pursuant to Section 2.02(e).

        (b) Exchange Procedures. Promptly after the Effective Time, Buyer shall
    instruct the Exchange Agent and the Exchange Agent shall mail to each holder
    of record of a certificate or certificates which immediately prior to the
    Effective Time represented outstanding shares of Seller Common Stock (the
    "Certificates") whose shares were converted pursuant to Section 2.01 into
    the right to receive shares of Buyer Common Stock (i) a letter of
    transmittal (which shall specify that delivery shall be effected, and risk
    of loss and title to the Certificates shall pass, only upon delivery of the
    Certificates to the Exchange Agent, and shall be in such form and have such
    other provisions as Buyer and Seller may reasonably specify) and
    (ii) instructions for effecting the surrender of the Certificates in
    exchange for certificates representing shares of Buyer Common Stock (plus
    cash in lieu of fractional shares, if any, of Buyer Common Stock as provided
    below). Upon surrender of a Certificate for cancellation to the Exchange
    Agent or to such other agent or agents as may be appointed by Buyer,
    together with such letter of transmittal, duly executed, the holder of such
    Certificate shall be entitled to receive in exchange therefor a certificate
    representing that number of whole shares of Buyer Common Stock which such
    holder has the right to receive pursuant to the provisions of this
    Article II, and the Certificate so surrendered shall immediately be
    cancelled. In the event of a transfer of ownership of Seller Common Stock
    which is not registered in the transfer records of Seller, a certificate
    representing the proper number of shares of Buyer Common Stock may be issued
    to a transferee if the Certificate representing such Seller Common Stock is
    presented to the Exchange Agent, accompanied by all documents required to
    evidence and effect such transfer and by evidence that any applicable stock
    transfer taxes have been paid. Until surrendered as contemplated by this
    Section 2.02, each Certificate shall be deemed at any time after the
    Effective Time to represent only the right to receive upon such surrender
    the certificate representing shares of Buyer Common Stock and cash in lieu
    of any fractional shares of Buyer Common Stock as contemplated by this
    Section 2.02.

        (c) Distributions with Respect to Unexchanged Shares. No dividends or
    other distributions declared or made after the Effective Time with respect
    to Buyer Common Stock with a record date after the Effective Time shall be
    paid to the holder of any unsurrendered Certificate with respect to the
    shares of Buyer Common Stock represented thereby and no cash payment in lieu
    of fractional shares shall be paid to any such holder pursuant to subsection
    (e) below until the holder of record of such Certificate shall surrender
    such Certificate. Subject to the effect of applicable laws, following
    surrender of any such Certificate, there shall be paid to the record holder
    of the certificates representing whole shares of Buyer Common Stock issued
    in exchange therefor, without interest, (i) at the time of such surrender,
    the amount of any cash payable in lieu of a fractional share of Buyer Common
    Stock to which such holder is entitled pursuant to subsection (e) below and
    the amount of dividends or other distributions with a record date after the
    Effective Time previously paid with respect to such whole shares of Buyer
    Common Stock, and (ii) at the appropriate payment date, the amount of
    dividends or other distributions with a record date after the Effective Time
    but prior to surrender and a payment date subsequent to surrender payable
    with respect to such whole shares of Buyer Common Stock.

        (d) No Further Ownership Rights in Seller Common Stock. All shares of
    Buyer Common Stock issued upon the surrender for exchange of Certificates in
    accordance with the terms hereof (including any cash paid pursuant to
    subsection (c) or (e) of this Section 2.02) shall be deemed to have been
    issued in full satisfaction of all rights pertaining to such shares of
    Seller Common Stock, subject, however, to the Surviving Corporation's
    obligation to pay any dividends or make any other

                                      A-3
<PAGE>
    distributions with a record date prior to the Effective Time which may have
    been declared or made by Seller on such shares of Seller Common Stock in
    accordance with the terms of this Agreement (to the extent permitted under
    Section 5.01) prior to the date hereof and which remain unpaid at the
    Effective Time, and from and after the Effective Time there shall be no
    further registration of transfers on the stock transfer books of the
    Surviving Corporation of the shares of Seller Common Stock 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 cancelled and exchanged as provided in this Section
    2.02.

        (e) No Fractional Shares. No certificate or scrip representing
    fractional shares of Buyer Common Stock shall be issued upon the surrender
    for exchange of Certificates, and such fractional share interests will not
    entitle the owner thereof to vote or to any other rights of a stockholder of
    Buyer. Notwithstanding any other provision of this Agreement, each holder of
    shares of Seller Common Stock exchanged pursuant to the Merger who would
    otherwise have been entitled to receive a fraction of a share of Buyer
    Common Stock (after taking into account all Certificates delivered by such
    holder) shall receive, in lieu thereof, cash (without interest) in an amount
    equal to such fractional part of a share of Buyer Common Stock multiplied by
    the average of the last reported sales prices of Buyer Common Stock, as
    reported on the Nasdaq National Market, on each of the ten trading days
    immediately preceding the Closing Date.

        (f) Termination of Exchange Fund. Any portion of the Exchange Fund which
    remains undistributed to the stockholders of Seller for 180 days after the
    Effective Time shall be delivered to Buyer, upon demand, and any
    stockholders of Seller who have not previously complied with this Section
    2.02 shall thereafter look only to Buyer for payment of their claim for
    Buyer Common Stock, any cash in lieu of fractional shares of Buyer Common
    Stock and any dividends or distributions with respect to Buyer Common Stock.

        (g) No Liability. To the extent permitted by applicable law, neither
    Buyer nor Seller shall be liable to any holder of shares of Seller Common
    Stock or Buyer Common Stock, as the case may be, for such shares (or
    dividends or distributions with respect thereto) delivered to a public
    official pursuant to any applicable abandoned property, escheat or similar
    law.

        (h) Withholding Rights. Each of Buyer and the Surviving Corporation
    shall be entitled to deduct and withhold from the consideration otherwise
    payable pursuant to this Agreement to any holder of shares of Seller Common
    Stock such amounts as it is required to deduct and withhold with respect to
    the making of such payment under the Code, or any provision of state, local
    or foreign tax law. To the extent that amounts are so withheld by Surviving
    Corporation or Buyer, as the case may be, such withheld amounts shall be
    treated for all purposes of this Agreement as having been paid to the holder
    of the shares of Seller Common Stock in respect of which such deduction and
    withholding was made by Surviving Corporation or Buyer, as the case may be.

        (i) Lost Certificates. If any Certificate shall have been lost, stolen
    or destroyed, upon the making of an affidavit of that fact by the person
    claiming such Certificate to be lost, stolen or destroyed and, if required
    by the Surviving Corporation, the posting by such person of a bond in such
    reasonable amount as the Surviving Corporation may direct as indemnity
    against any claim that may be made against it with respect to such
    Certificate, the Exchange Agent will issue in exchange for such lost, stolen
    or destroyed Certificate the shares of Buyer Common Stock and any cash in
    lieu of fractional shares, and unpaid dividends and distributions on shares
    of Buyer Common Stock deliverable in respect thereof pursuant to this
    Agreement.

                                  ARTICLE III
                    REPRESENTATIONS AND WARRANTIES OF SELLER

    Seller represents and warrants to Buyer and Sub that the statements
contained in this Article III are true and correct, except as set forth herein
and in the disclosure schedule delivered by Seller to Buyer on or before the
date of this Agreement (the "Seller Disclosure Schedule"). The Seller Disclosure
Schedule shall be arranged in paragraphs corresponding to the numbered and
lettered paragraphs contained in this Article III and the disclosure in any
paragraph shall qualify other paragraphs in this Article III only to the extent
that it is reasonably apparent from a reading of such disclosure that it also
qualifies or applies to such other paragraphs.

    SECTION 3.01 ORGANIZATION OF SELLER.  Seller and each of its Subsidiaries
(as defined below) which is a corporation is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation, has all requisite corporate power to own, lease and operate its
property and to carry on its business as now being conducted and as proposed to
be conducted, and is duly qualified to do business and is in good standing as a
foreign corporation in each jurisdiction in which the failure to be so qualified
would have a material adverse effect on the business, properties, financial
condition or results of operations of Seller and its Subsidiaries, taken as a
whole (a "Seller Material Adverse Effect"); provided, however, that for purposes
of this Agreement, any adverse change in the stock price of Seller, as quoted on
the Nasdaq National Market, shall not be taken into account in determining
whether there has been or would be a "Seller Material Adverse Effect" on or with
respect to Seller and its Subsidiaries, taken as a whole. Each of Seller's
Subsidiaries which is a limited partnership or a limited liability company is
validly existing and in good standing under the laws of the jurisdiction of its
formation, has all requisite statutory power to own, lease and operate its
property and to carry on its business as now being conducted and as proposed to
be conducted, and is duly qualified to do business and is in good standing as a
foreign limited partnership or foreign limited liability company, as the case
may be, in each jurisdiction in which the failure to be so qualified would have
a Seller Material Adverse Effect. Except as set forth in the Seller SEC Reports
(as defined in Section 3.04(a)) filed on or prior to the date hereof and except
for inactive Subsidiaries, neither Seller nor any of its Subsidiaries directly
or indirectly owns any equity or similar interest in, or any interest
convertible into or exchangeable or exercisable for, any corporation,
partnership, joint venture or other business association or entity, excluding
securities in any publicly traded company held for investment by Seller and
comprising less than five percent (5%) of the outstanding stock of such company.
As used in this Agreement, the word "Subsidiary" means, with respect to any
party, any corporation or other organization, whether incorporated or
unincorporated, of which (i) such party or any other Subsidiary of such party is
a general partner or member (excluding partnerships and limited liability
companies, the general partnership or membership interests of which held by such
party or any Subsidiary of such party do not have a majority of the voting
interest in such partnership or limited liability company liability company or
veto rights with respect to decisions made by or on behalf of such partnership
or limited liability company), or (ii) at least a majority of the securities or
other interests having by their terms ordinary voting power to elect a majority
of the Board of Directors or others performing similar functions with respect to
such corporation or other organization is directly or indirectly owned or
controlled by such party or by any one or more of its Subsidiaries, or by such
party and one or more of its Subsidiaries.

    SECTION 3.02 SELLER CAPITAL STRUCTURE.

    (a) The authorized capital stock of Seller consists of 40,000,000 shares of
Common Stock ("Seller Common Stock") and 10,000,000 shares of Preferred Stock,
("Seller Preferred Stock"). As of November 30, 1998, (i) 13,263,960 shares of
Seller Common Stock were issued and outstanding, all of which are validly
issued, fully paid and nonassessable, (ii) no shares of Seller Common Stock were
held in the treasury of Seller or by Subsidiaries of Seller, and (iii) no shares
of Seller Preferred Stock were

                                      A-5
<PAGE>
issued and outstanding. The Seller Disclosure Schedule shows the number of
shares of Seller Common Stock reserved for future issuance pursuant to stock
options and warrants granted and outstanding as of November 30, 1998 and the
plans under which such options were granted, if applicable (collectively, the
"Seller Stock Plans"). No material change in such capitalization has occurred
between November 30, 1998 and the date of this Agreement. All shares of Seller
Common Stock subject to issuance as specified above are duly authorized and,
upon issuance on the terms and conditions specified in the instruments pursuant
to which they are issuable, shall be validly issued, fully paid and
nonassessable. There are no obligations, contingent or otherwise, of Seller or
any of its Subsidiaries to repurchase, redeem or otherwise acquire any shares of
Seller Common Stock, Seller Preferred Stock, or the capital stock of any
Subsidiary or to provide funds to or make any material investment (in the form
of a loan, capital contribution or otherwise) in any such Subsidiary or any
other entity other than guarantees of bank obligations of Subsidiaries entered
into in the ordinary course of business. All of the outstanding shares of
capital stock or other equity interests of or in each of Seller's Subsidiaries
are duly authorized, validly issued, fully paid and nonassessable and all such
shares (other than directors' qualifying shares in the case of foreign
Subsidiaries) and other equity interests are owned by Seller or another
Subsidiary free and clear of all security interests, liens, claims, pledges,
agreements, limitations in Seller's voting rights, charges or other encumbrances
of any nature.

    (b) Except as set forth in this Section 3.02 or as reserved for future
grants of options and warrants under the Seller Stock Plans, there are no equity
securities of any class of Seller or any of its Subsidiaries, or any security
exchangeable into or exercisable for such equity securities, issued, reserved
for issuance or outstanding, and there are no options, warrants, equity
securities, calls, rights, commitments or agreements of any character to which
Seller or any of its Subsidiaries is a party or by which such entity is bound
(including under letters of intent, whether binding or nonbinding) obligating
Seller or any of its Subsidiaries to issue, deliver or sell, or cause to be
issued, delivered or sold, additional shares of capital stock or other equity
interests of Seller or any of its Subsidiaries or obligating Seller or any of
its Subsidiaries to grant, extend, accelerate the vesting of, otherwise modify
or amend or enter into any such option, warrant, equity security, call, right,
commitment or agreement. To the best knowledge of Seller, there are no voting
trusts, proxies or other voting agreements or understandings with respect to the
shares of capital stock or other equity interests of Seller or any Subsidiary
other than the Seller Voting Agreements.

    (c) No consent of the holders of the Seller Stock Options or Warrants (as
defined in Section 6.12) is required in connection with the conversion of the
Seller Stock Options or Warrants into options or warrants, as the case may be,
to acquire Buyer Common Stock in accordance with Section 6.12.

    SECTION 3.03 AUTHORITY; NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

    (a) Seller has all requisite corporate power and authority to enter into
this Agreement and the Seller Stock Option Agreement and to consummate the
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement and the Seller Stock Option Agreement and the consummation of the
transactions contemplated hereby and thereby by Seller have been duly authorized
by all necessary corporate action on the part of Seller, subject only to the
approval of the Merger by Seller's stockholders under the NJBCA. Assuming the
Buyer's representations and warranties contained in Article IV hereof are true,
the vote of Seller's stockholders required to approve this Agreement and the
Merger is a majority of the votes cast by the holders of Seller Common Stock on
the record date for the Seller Meeting (as defined in Section 3.15), at which a
quorum is present. This Agreement and the Seller Stock Option Agreement have
been duly executed and delivered by Seller and constitute the valid and binding
obligations of Seller, enforceable against Seller in accordance with their
terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting
creditors' rights and to general equity principles (the "Bankruptcy and Equity
Exception").

                                      A-6
<PAGE>
    (b) The execution and delivery of this Agreement and the Seller Stock Option
Agreement by Seller does not, and the consummation of the transactions
contemplated hereby and thereby will not, (i) conflict with, or result in any
violation or breach of, any provision of the Certificate of Incorporation or
Bylaws of Seller, (ii) result in any violation or breach of, or constitute (with
or without notice or lapse of time, or both) a default (or give rise to a right
of termination, cancellation or acceleration of any obligation or loss of any
material benefit) under, or require a consent or waiver under, any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, lease, contract
or other agreement, instrument or obligation to which Seller or any of its
Subsidiaries is a party or by which any of them or any of their properties or
assets may be bound, or (iii) conflict with, violate, or cause the termination
of any permit, concession, franchise, license, judgment, order, decree, statute,
law, ordinance, rule or regulation applicable to Seller or any of its
Subsidiaries or any of its or their properties or assets, except in the case of
(ii) and (iii) for any such conflicts, violations, defaults, terminations,
cancellations or accelerations which are not, individually or in the aggregate,
reasonably likely to have a Seller Material Adverse Effect.

    (c) No consent, approval, order or authorization of, or registration,
declaration or filing with, any court, administrative agency or commission or
other governmental authority or instrumentality ("Governmental Entity") is
required by or with respect to Seller or any of its Subsidiaries in connection
with the execution and delivery of this Agreement or the Seller Stock Option
Agreement or the consummation of the transactions contemplated hereby or
thereby, except for (i) the filing of the pre-merger notification report under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, ("HSR
Act"), (ii) the filing of the Certificate of Merger with the New Jersey
Treasurer, (iii) the filing of the Joint Proxy Statement (as defined in Section
3.15 below) with the Securities and Exchange Commission (the "SEC") in
accordance with the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), (iv) such consents, approvals, orders, authorizations, registrations,
declarations and filings as may be required under applicable state securities
laws and the laws of any foreign country and (v) such other consents,
authorizations, filings, approvals and registrations which, if not obtained or
made, would not materially interfere with the operations of any material
facility of Seller or otherwise be reasonably likely to have a Seller Material
Adverse Effect.

    SECTION 3.04 SEC FILINGS; FINANCIAL STATEMENTS.

    (a) Seller has filed and made available to Buyer all forms, reports and
documents required to be filed by Seller with the SEC since January 1, 1996
other than registration statements on Form S-8 (collectively, the "Seller SEC
Reports"). The Seller SEC Reports (i) at the time filed, complied in all
material respects with the applicable requirements of the Securities Act of
1933, as amended (the "Securities Act"), and the Exchange Act, as the case may
be, and (ii) did not at the time they were filed (or if amended or superseded by
a filing prior to the date of this Agreement, then on the date of such filing)
contain any untrue statement of a material fact or omit to state a material fact
required to be stated in such Seller SEC Reports or necessary in order to make
the statements in such Seller SEC Reports, in the light of the circumstances
under which they were made, not misleading. None of Seller's Subsidiaries is
required to file any forms, reports or other documents with the SEC.

    (b) Each of the consolidated financial statements (including, in each case,
any related notes) contained in the Seller SEC Reports complied as to form in
all material respects with the applicable published rules and regulations of the
SEC with respect thereto, was prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
involved (except as may be indicated in the notes to such financial statements
or, in the case of unaudited statements, as permitted by Form 10-Q of the SEC)
and fairly presented the consolidated financial position of Seller and its
Subsidiaries as of the dates and the consolidated results of its operations and
cash flows for the periods indicated, except that the unaudited interim
financial statements were or are subject to normal and recurring year-end
adjustments which were not or are not expected to be

                                      A-7
<PAGE>
material in amount. The unaudited balance sheet of Seller as of September 30,
1998 is referred to herein as the "Seller Balance Sheet."

    SECTION 3.05 NO UNDISCLOSED LIABILITIES.  Except as disclosed in the Seller
SEC Reports filed prior to the date hereof, and except for normal or recurring
liabilities incurred since September 30, 1998 in the ordinary course of business
consistent with past practices, Seller and its Subsidiaries do not have any
liabilities, either accrued, contingent or otherwise (whether or not required to
be reflected in financial statements in accordance with generally accepted
accounting principles), and whether due or to become due, which individually or
in the aggregate are reasonably likely to have a Seller Material Adverse Effect.

    SECTION 3.06 ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed in
the Seller SEC Reports filed prior to the date hereof, since the date of the
Seller Balance Sheet, Seller and its Subsidiaries have conducted their
businesses only in the ordinary course and in a manner consistent with past
practice and, since such date, there has not been (i) any change in the
financial condition, results of operations, business or properties of Seller and
its Subsidiaries, taken as a whole that has had, or is reasonably likely to
have, a Seller Material Adverse Effect; (ii) any damage, destruction or loss
(whether or not covered by insurance) with respect to Seller or any of its
Subsidiaries having a Seller Material Adverse Effect; (iii) any material change
by Seller in its accounting methods, principles or practices to which Buyer has
not previously consented in writing; (iv) any revaluation by Seller of any of
its assets having a Seller Material Adverse Effect; or (v) any other action or
event that would have required the consent of Buyer pursuant to Section 5.01 of
this Agreement had such action or event occurred after the date of this
Agreement.

    SECTION 3.07 TAXES.

    (a) For the purposes of this Agreement, a "Tax" or, collectively, "Taxes,"
means any and all federal, state, local and foreign taxes, assessments and other
governmental charges, duties, fees, levies, impositions and liabilities,
including without limitation, income, gross receipts, profits, sales, use and
occupation, and value added, ad valorem, transfer, gains, franchise,
withholding, payroll, recapture, employment, excise, unemployment insurance,
social security, business license, occupation, business organization, stamp,
environmental, personal property, real property, worker's compensation, license,
lease, service, service use, severance, windfall profits, customs and other
taxes, together with all interest, fines, penalties and additions imposed with
respect to such amounts and any obligations under any agreements or arrangements
with any other person with respect to such amounts and including any liability
for taxes of a predecessor entity. For purposes of this Agreement, "Tax Returns"
means all reports, returns, declarations, statements or other information
required to be supplied to a taxing authority in connection with Taxes.

    (b) Seller and each of its Subsidiaries have (i) filed all federal, state,
local and foreign Tax Returns required to be filed by them prior to the date of
this Agreement (taking into account extensions), (ii) paid or accrued all Taxes
due and payable, and (iii) paid or accrued all Taxes for which a notice of
assessment or collection has been received (other than amounts being contested
in good faith by appropriate proceedings), except in the case of clause (i),
(ii) or (iii) for any such filings, payments or accruals which are not
reasonably likely, individually or in the aggregate, to have a Seller Material
Adverse Effect. The unpaid Taxes of the Seller and each of its Subsidiaries for
tax periods through the Seller Balance Sheet date do not exceed the accruals and
reserves for Taxes (excluding reserves for deferred Taxes) set forth on the
Seller Balance Sheet by an amount that would have a Seller Material Adverse
Effect. Neither the Internal Revenue Service (the "IRS") nor any other taxing
authority has asserted any claim for Taxes, or to the actual knowledge of the
executive officers of Seller, is threatening to assert any claims for Taxes,
which claims, individually or in the aggregate, are reasonably likely to have a
Seller Material Adverse Effect. Seller and each of its Subsidiaries have
withheld or collected and paid over to the appropriate governmental authorities
(or are properly holding for such

                                      A-8
<PAGE>
payment) all Taxes required by law to be withheld or collected, except for
amounts which are not reasonably likely, individually or in the aggregate, to
have a Seller Material Adverse Effect. There are no liens for Taxes upon the
assets of Seller or any of its Subsidiaries (other than liens for taxes that are
not yet due or that are being contested in good faith by appropriate
proceedings), except for liens which are not reasonably likely, individually or
in the aggregate, to have a Seller Material Adverse Effect.

    (c) Seller is not and never has been a party to or bound by any Tax
indemnity, Tax sharing or Tax allocation agreement (whether written or unwritten
or arising under operation of federal law as a result of being a member of a
group filing consolidated or combined Tax Returns, under operation of certain
state laws as a result of being a member of a combined, consolidated or unitary
group, or under comparable laws of other states or foreign jurisdictions) which
includes a party other than Seller and its Subsidiaries nor does Seller owe any
amount under any such agreement.

    (d) Neither Seller nor any of its Subsidiaries is a "consenting corporation"
within the meaning of Section 341(f) of the Code, and none of the assets of
Seller or the Subsidiaries are subject to an election under Section 341(f) of
the Code.

    (e) Neither Seller nor any of its Subsidiaries has been a United States real
property holding corporation with the meaning of Section 897(c)(2) of the Code
during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code.

    (f) Neither Seller nor any of its Subsidiaries has made any payments, is
obligated to make any payments, or is a party to any agreement that could
obligate it to make any payments that will be an "excess parachute payment"
under Section 280G of the Code as a result of the transactions contemplated by
this Agreement.

    SECTION 3.08 PROPERTIES.

    (a) Seller has provided to Buyer a true and complete list of all real
property leased by Seller or its Subsidiaries pursuant to leases providing for
the occupancy of facilities in excess of 10,000 square feet (collectively
"Material Lease(s)") and the location of the premises. With respect to each such
Material Lease: (i) the lease is legal, valid, binding, enforceable against
Seller subject to the Bankruptcy and Equity Exception, and in full force and
effect; (ii) the lease will continue to be legal, valid, binding, enforceable
and in full force and effect immediately following the Closing in accordance
with the terms thereof as in effect prior to the Closing; (iii) neither Seller
nor, to the Seller's knowledge, any other party to the lease or sublease is in
breach or default, and no event has occurred which, with notice or lapse of
time, would constitute a breach or default or permit termination, modification
or acceleration thereunder; and (iv) Seller has not assigned, transferred,
conveyed, mortgaged, deeded in trust or encumbered any interest in the leasehold
or subleasehold; except, in the case of clauses (i) through (iv) that the same
is not reasonably likely to have a Seller Material Adverse Effect.

    (b) Seller has provided to Buyer a true and complete list of all real
property that Seller or any of its Subsidiaries owns (the "Owned Real
Property"). With respect to each such parcel of Owned Real Property (a) Seller
or the identified Subsidiary has good and clear record and marketable title to
such property, insurable by a recognized national title insurance company at
standard rates, free and clear of any security interest, easement, covenant or
other restriction, except for recorded easements, covenants and other
restrictions which do not materially impair the current uses or occupancy of
such property; (b) there are no (i) condemnation proceedings pending or, to
Seller's knowledge, threatened relating to such parcel or (ii) litigation or
administrative actions pending or, to Seller's knowledge, threatened relating to
such parcel; (c) the legal description for such parcel contained in the deed
thereof describes such parcel fully and adequately; the buildings and
improvements located thereon are located within the boundary lines of the
described parcels of land, are not in violation of current setback requirements,
zoning laws and ordinances and do not encroach on any easement which may burden
the

                                      A-9
<PAGE>
land; the land does not serve any adjoining property for any purpose
inconsistent with the use of the land as heretofore used; and such parcel is not
subject to any restriction for which any permits or licenses necessary to the
use thereof as heretofore used have not been obtained; (d) there are no leases,
subleases or agreements granting to any party or parties the right of use or
occupancy of any portion of such parcel; and (e) to Seller's knowledge, each
parcel is an independent unit which does not rely on any facilities (other than
the facilities of public utility and water companies) located on any other
property (i) to fulfill any zoning, building code or other municipal or
governmental requirement; (ii) for structural support or the furnishing of any
essential building systems or utilities, including but not limited to electric,
plumbing, mechanical, heating, ventilating and air conditioning systems; or
(iii) to fulfill the requirements of any lease. To Seller's knowledge, no
building or other improvement not included in the parcel relies on any part of
the parcel to fulfill any zoning, building code or other municipal or
governmental requirement or for structural support or the furnishing of any
essential building systems or utilities. Such parcel is assessed by local
property assessors as a tax parcel or parcels separate from all other tax
parcels.

    SECTION 3.09 AGREEMENTS, CONTRACTS AND COMMITMENTS.  Seller has not
breached, or received in writing any claim or notice that it has breached, any
of the terms or conditions of any material agreement, contract or commitment
filed as an exhibit to the Seller SEC Reports or any other agreement, contract
or commitment, the termination of which would have a Seller Material Adverse
Effect ("Seller Material Contracts") in such a manner as, individually or in the
aggregate, are reasonably likely to have a Seller Material Adverse Effect. Each
Seller Material Contract that has not expired by its terms is in full force and
effect, and no party to any of the Seller Material Contracts will have the right
to terminate such contract as a result of the transactions contemplated by this
Agreement. None of the Seller Material Contracts is currently being
renegotiated, and Seller has no knowledge that any Seller Material Contract will
be the subject of a voluntary or regulatory ordered renegotiation within 12
months after the date of this Agreement.

    SECTION 3.10 LITIGATION.  Except as described in the Seller SEC Reports
filed prior to the date hereof, there is no action, suit or proceeding, claim,
arbitration or investigation against Seller pending or as to which Seller has
received any written notice of assertion, which, individually or in the
aggregate, is reasonably likely to have a Seller Material Adverse Effect or a
material adverse effect on the ability of Seller to consummate the transactions
contemplated by this Agreement.

    SECTION 3.11 ENVIRONMENTAL MATTERS.

    (a) Except as disclosed in the Seller SEC Reports filed prior to the date
hereof and except for such matters that, individually or in the aggregate, are
not reasonably likely to have a Seller Material Adverse Effect: (i) Seller and
its Subsidiaries have complied and are currently in compliance with all
applicable Environmental Laws (as defined in Section 3.11(b)); (ii) the
properties currently owned or operated by Seller and its Subsidiaries (including
soils, groundwater, surface water, buildings or other structures) are not
contaminated with any Hazardous Substances (as defined in Section 3.11(c));
(iii) the properties formerly owned or operated by Seller or any of its
Subsidiaries were not contaminated with Hazardous Substances during the period
of ownership or operation by Seller or any of its Subsidiaries; (iv) neither
Seller nor its Subsidiaries are subject to liability for any Hazardous Substance
disposal or contamination on any third party property; (v) neither Seller nor
any of its Subsidiaries has been associated with any release or threat of
release of any Hazardous Substance; (vi) neither Seller nor any of its
Subsidiaries has received any notice, demand, letter, claim or request for
information alleging that Seller or any of its Subsidiaries may be in violation
of or liable under any Environmental Law; (vii) neither Seller nor any of its
Subsidiaries is subject to any orders, decrees, injunctions or other
arrangements with any Governmental Entity or is subject to any indemnity or
other agreement with any third party relating to liability under any
Environmental Law or relating to Hazardous Substances; and (viii) there are no
circumstances or conditions involving Seller or any of its

                                      A-10
<PAGE>
Subsidiaries that could reasonably be expected to result in any claims,
liability, investigations, costs or restrictions on the ownership, use,
operation or transfer of any property or facility of Seller pursuant to any
Environmental Law.

    (b) As used herein, the term "Environmental Law" means any federal, state,
local or foreign law, regulation, order, decree, permit, authorization, opinion,
common law or agency requirement relating to: (A) the protection, investigation
or restoration of the environment, health and safety, or natural resources,
(B) the handling, use, presence, disposal, release or threatened release of any
Hazardous Substance or (C) noise, odor, wetlands, pollution, contamination or
any injury or threat of injury to persons, property or the environment.

    (c) As used herein, the term "Hazardous Substance" means any substance that
is: (A) listed, classified or regulated pursuant to any Environmental Law;
(B) any petroleum product or by-product, asbestos-containing material,
lead-containing paint or plumbing, polychlorinated biphenyls, radioactive
materials or radon; or (C) any other substance which is the subject of
regulatory action by any Governmental Entity pursuant to any Environmental Law.

    SECTION 3.12 EMPLOYEE BENEFIT PLANS.

    (a) Seller has listed in Section 3.12 of the Seller Disclosure Schedule all
employee benefit plans (as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")) and all bonus, stock option,
stock purchase, incentive, deferred compensation, supplemental retirement,
severance, welfare, fringe benefit and other similar employee benefit plans, and
all unexpired severance agreements, written or otherwise, for the benefit of, or
relating to, any current or former employee, director or independent contractor
providing services to Seller, any Subsidiary, or any entity which is a member
(an "ERISA Affiliate") of (i) a controlled group of corporations, (ii) a group
of trades or businesses (whether or not incorporated) under common control with
Seller, or (iii) an affiliated service group, all within the meaning of Section
414 of the Code, of which includes the Seller, or any Subsidiary of Seller
(together, the "Seller Employee Plans").

    (b) With respect to each Seller Employee Plan, Seller has made available to
Buyer, a true and correct copy of (i) the most recent annual report (Form 5500)
filed with the IRS (and the related financial statement), (ii) such Seller
Employee Plan, (iii) each trust agreement and group annuity contract, if any,
relating to such Seller Employee Plan and (iv) the most recent actuarial report
or valuation relating to a Seller Employee Plan subject to Title IV of ERISA.

    (c) With respect to the Seller Employee Plans, individually and in the
aggregate, no event has occurred, and to the knowledge of Seller, there exists
no condition or set of circumstances in connection with which Seller could be
subject to any liability that is reasonably likely to have a Seller Material
Adverse Effect under ERISA, the Code or any other applicable law.

    (d) With respect to the Seller Employee Plans, individually and in the
aggregate, there are no funded benefit obligations for which contributions have
not been made or properly accrued and there are no unfunded benefit obligations
which have not been accounted for by reserves, or otherwise properly footnoted
in accordance with generally accepted accounting principles, on the financial
statements of Seller, which obligations are reasonably likely to have a Seller
Material Adverse Effect.

    (e) Except as disclosed in Seller SEC Reports filed prior to the date of
this Agreement, and except as provided for in this Agreement, neither Seller nor
any of its Subsidiaries is a party to any oral or written (i) agreement with any
current or former officer or other key employee of Seller or any of its
Subsidiaries, the benefits of which are contingent, or the terms of which are
materially altered, upon the occurrence of a transaction involving Seller of the
nature contemplated by this Agreement, (ii) agreement with any current or former
officer of Seller providing any term of employment or compensation guarantee
extending for a period longer than one year from the date hereof and for the

                                      A-11
<PAGE>
payment of compensation in excess of $100,000 per annum, or (iii) agreement or
plan, including any stock option plan, stock appreciation right plan, restricted
stock plan or stock purchase plan, any of the benefits of which will be
increased, or the vesting or funding of the benefits of which will be
accelerated, by the occurrence of any of the transactions contemplated by this
Agreement or the value of any of the benefits of which will be calculated on the
basis of any of the transactions contemplated by this Agreement.

    (f) There are no pending, or threatened claims, actions, suits, termination
proceedings, or investigations by any Governmental Entity, against or involving
any Seller Benefit Plan; any Seller Benefit Plan intended to be qualified under
Section 401(a) of the Code has received a determination letter from the Internal
Revenue Service to that effect, which has not been revoked, and nothing has
occurred since the date of the most recent determination letter that would
adversely affect such qualification.

    SECTION 3.13 COMPLIANCE WITH LAWS.  Seller has complied with, is not in
violation of, and has not received any notices of violation with respect to, any
federal, state or local statute, law or regulation with respect to the conduct
of its business, or the ownership or operation of its business, except for
failures to comply or violations which, individually or in the aggregate, have
not had and are not reasonably likely to have a Seller Material Adverse Effect.
No officer or director of Seller or any of its Subsidiaries or holder of greater
than 5% of the outstanding capital stock of Seller would disqualify Buyer from
obtaining any permits necessary for the business of Buyer or disqualify Seller
or Buyer from bidding on or being awarded any government contract.

    SECTION 3.14 ACCOUNTING AND TAX MATTERS.  To its knowledge, after consulting
with its independent auditors, neither Seller nor any of its Affiliates (as
defined in Section 6.10) has taken or agreed to take any action which would
(i) prevent Buyer from accounting for the business combination to be effected by
the Merger as a pooling of interests or (ii) prevent the Merger from
constituting a transaction qualifying as a reorganization under 368(a) of the
Code.

    SECTION 3.15 REGISTRATION STATEMENT; PROXY STATEMENT/PROSPECTUS.  The
information to be supplied by Seller for inclusion in the registration statement
on Form S-4 pursuant to which shares of Buyer Common Stock issued in the Merger
will be registered under the Securities Act (the "Registration Statement"),
shall not at the time the Registration Statement is declared effective by the
SEC contain any untrue statement of a material fact or omit to state any
material fact required to be stated in the Registration Statement or necessary
in order to make the statements in the Registration Statement, in light of the
circumstances under which they were made, not misleading. The information
supplied by Seller for inclusion in the joint proxy statement/prospectus to be
sent to the stockholders of Buyer and Seller in connection with the meeting of
Seller's stockholders to consider this Agreement and the Merger (the "Seller
Meeting") and in connection with the meeting of Buyer's stockholders (the "Buyer
Meeting") to consider the issuance of shares of Buyer Common Stock pursuant to
the Merger (the "Joint Proxy Statement") shall not, on the date the Joint Proxy
Statement is first mailed to stockholders of Seller or Buyer, at the time of the
Seller Meeting and the Buyer Meeting and at the Effective Time, contain any
statement which, at such time and in light of the circumstances under which it
shall be made, is false or misleading with respect to any material fact, or omit
to state any material fact necessary in order to make the statements made in the
Joint Proxy Statement not false or misleading; or omit to state any material
fact necessary to correct any statement in any earlier communication with
respect to the solicitation of proxies for the Seller Meeting or the Buyer
Meeting which has become false or misleading. If at any time prior to the
Effective Time any event relating to Seller or any of its Affiliates, officers
or directors should be discovered by Seller which should be set forth in an
amendment to the Registration Statement or a supplement to the Joint Proxy
Statement, Seller shall promptly inform Buyer.

                                      A-12
<PAGE>
    SECTION 3.16 LABOR MATTERS.  Neither Seller nor any of its Subsidiaries is a
party to or otherwise bound by any collective bargaining agreement, contract or
other agreement or understanding with a labor union or labor organization, nor,
as of the date hereof, is Seller or any of its Subsidiaries the subject of any
material proceeding asserting that Seller or any of its Subsidiaries has
committed an unfair labor practice or is seeking to compel it to bargain with
any labor union or labor organization nor, as of the date of this Agreement, is
there pending or, to the knowledge of the executive officers of Seller,
threatened, any material labor strike, dispute, walkout, work stoppage,
slow-down or lockout involving Seller or any of its Subsidiaries.

    SECTION 3.17 NO EXISTING DISCUSSIONS.  As of the date hereof, Seller is not
engaged, directly or indirectly, in any discussions or negotiations with any
other party with respect to an Acquisition Proposal (as defined in Section
6.01(a)).

    SECTION 3.18 OPINION OF FINANCIAL ADVISOR.  The financial advisors of
Seller, Credit Suisse First Boston Corporation and CIBC World Markets Corp.,
have each delivered to the Board of Directors of Seller an opinion dated the
date of this Agreement to the effect that the Exchange Ratio in the Merger is
fair to the holders of Seller Common Stock from a financial point of view.

    SECTION 3.19 ANTI-TAKEOVER LAWS.  Assuming the accuracy of the
representations and warranties set forth in Article IV hereto, Seller has taken
all actions necessary such that no "fair price", "business combination",
"control share acquisition", or similar statute will be applicable to the
transactions contemplated by this Agreement.

                                   ARTICLE IV
                REPRESENTATIONS AND WARRANTIES OF BUYER AND SUB

    Buyer and Sub jointly and severally represent and warrant to Seller that the
statements contained in this Article IV are true and correct, except as set
forth herein in the disclosure schedule delivered by Buyer and Sub to Seller on
or before the date of this Agreement (the "Buyer Disclosure Schedule"). The
Buyer Disclosure Schedule shall be arranged in paragraphs corresponding to the
numbered and lettered paragraphs contained in this Article IV and the disclosure
in any paragraph shall qualify other paragraphs in this Article IV only to the
extent that it is reasonably apparent from a reading of such disclosure that it
also qualifies or applies to such other paragraphs.

    SECTION 4.01 ORGANIZATION OF BUYER AND SUB.  Buyer and Sub and each of
Buyer's other Subsidiaries which is a corporation is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation, has all requisite corporate power to own,
lease and operate its property and to carry on its business as now being
conducted and as proposed to be conducted, and is duly qualified to do business
and is in good standing as a foreign corporation in each jurisdiction in which
the failure to be so qualified would have a material adverse effect on the
business, properties, financial condition or results of operations of Buyer and
its Subsidiaries, taken as a whole (a "Buyer Material Adverse Effect");
provided, however, that for purposes of this Agreement, any adverse change in
the stock price of Buyer, as quoted on the Nasdaq National Market, shall not be
taken into account in determining whether there has been or would be an "Buyer
Material Adverse Effect" on or with respect to Buyer and its Subsidiaries, taken
as a whole. Each of Buyer's Subsidiaries which is a limited partnership or a
limited liability company is validly existing and in good standing under the
laws of the jurisdiction of its formation, has all requisite statutory power to
own, lease and operate its property and to carry on its business as now being
conducted and as proposed to be conducted, and is duly qualified to do business
and is in good standing as a foreign limited partnership or foreign limited
liability company, as the case may be, in each jurisdiction in which the failure
to be so qualified would have a Buyer's Material Adverse Effect. Except as set
forth in the Buyer SEC Reports (as defined in Section 4.04(a)) filed prior to
the date hereof, neither Buyer nor any of its Subsidiaries directly or
indirectly owns any equity or similar

                                      A-13
<PAGE>
interest in, or any interest convertible into or exchangeable or exercisable
for, any corporation, partnership, joint venture or other business association
or entity, excluding securities in any publicly traded company held for
investment by Buyer and comprising less than five percent (5%) of the
outstanding stock of such company.

    SECTION 4.02 BUYER CAPITAL STRUCTURE.

    (a) The authorized capital stock of Buyer consists of (i) 100,000,000 shares
of Buyer Common Stock, (ii) 1,000,000 shares of Class B Common Stock, $.01 par
value ("Buyer Class B Common Stock"), and (iii) 1,000,000 shares of Preferred
Stock, $.01 par value (the "Buyer Preferred Stock"). As of November 30, 1998,
there were outstanding 13,819,473 shares of Buyer Common Stock, 988,200 shares
of Buyer Class B Common Stock, and no shares of Buyer Preferred Stock. The Buyer
Disclosure Schedule shows the number of shares of Buyer Common Stock reserved
for future issuance pursuant to stock options granted and outstanding as of
October 31, 1998, and the plans under which such options were granted
(collectively, the "Buyer Stock Plans"). There are no shares of Buyer Class B
Common Stock reserved for future issuance. Except for the issuance of additional
shares of Buyer Common Stock in acquisitions as set forth in the Buyer
Disclosure Schedule, no material change in such capitalization has occurred
between November 30, 1998 and the date of this Agreement. All shares of Buyer
Common Stock subject to issuance as specified above are duly authorized and,
upon issuance on the terms and conditions specified in the instruments pursuant
to which they are issuable, shall be validly issued, fully paid and
nonassessable. The shares of Buyer Common Stock to be issued in the Merger will,
when issued in accordance with the terms of this Agreement, be validly issued,
fully paid and nonassessable. There are no obligations, contingent or otherwise,
of Buyer or any of its Subsidiaries to repurchase, redeem or otherwise acquire
any shares of Buyer Common Stock, Buyer Class B Common Stock, Buyer Preferred
Stock or the capital stock of any Subsidiary or to provide funds to or make any
material investment (in the form of a loan, capital contribution or otherwise)
in any such Subsidiary or any other entity other than guarantees of bank
obligations of Subsidiaries entered into in the ordinary course of business. All
of the outstanding shares of capital stock of each of Buyer's Subsidiaries are
duly authorized, validly issued, fully paid and nonassessable and all such
shares (other than directors' qualifying shares in the case of foreign
Subsidiaries) are owned by Buyer or another Subsidiary free and clear of all
security interests, liens, claims, pledges, agreements, limitations in Buyer'
voting rights, charges or other encumbrances of any nature.

    (b) Except as set forth in this Section 4.02 or as reserved for future
grants of options under the Buyer Stock Plans, there are no equity securities of
any class of Buyer or any of its Subsidiaries, or any security exchangeable into
or exercisable for such equity securities, issued, reserved for issuance or
outstanding. There are no options, warrants, equity securities, calls, rights,
commitments or agreements of any character to which Buyer or any of its
Subsidiaries is a party or by which such entity is bound (including under
letters of intent, whether binding or nonbinding) obligating Buyer or any of its
Subsidiaries to issue, deliver or sell, or cause to be issued, delivered or
sold, additional shares of capital stock of Buyer or any of its Subsidiaries or
obligating Buyer or any of its Subsidiaries to grant, extend, accelerate the
vesting of, otherwise modify or amend or enter into any such option, warrant,
equity security, call, right, commitment or agreement. To the best knowledge of
Buyer, there are no voting trusts, proxies or other voting agreements or
understandings with respect to the shares of capital stock of Buyer.

    SECTION 4.03 AUTHORITY; NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

    (a) Each of Buyer and the Sub has all requisite corporate power and
authority to enter into this Agreement and to consummate the transactions
contemplated by this Agreement. The execution and delivery of this Agreement and
the consummation of the transactions contemplated by this Agreement have been
duly authorized by all necessary corporate action on the part of each of Buyer
and Sub

                                      A-14
<PAGE>
(including the approval of the Merger by Buyer as the sole stockholder of Sub),
subject only to the approval of the Buyer Voting Proposal (as defined in Section
6.05(b)) by Buyer's stockholders. The vote of Buyer's stockholders required to
approve the Buyer Voting Proposal is a majority of the total votes cast on the
proposal in person or by proxy. This Agreement has been duly executed and
delivered by each of Buyer and Sub and constitutes the valid and binding
obligation of each of Buyer and Sub, enforceable in accordance with its terms,
subject to the Bankruptcy and Equity Exception.

    (b) The execution and delivery of this Agreement by each of Buyer and Sub
does not, and the consummation of the transactions contemplated by this
Agreement will not, (i) conflict with, or result in any violation or breach of,
any provision of the Certificate of Incorporation or Bylaws of Buyer or Sub,
(ii) result in any violation or breach of, or constitute (with or without notice
or lapse of time, or both) a default (or give rise to a right of termination,
cancellation or acceleration of any obligation or loss of any material benefit)
under, or require a consent or waiver under, any of the terms, conditions or
provisions of any note, bond, mortgage, indenture, lease, contract or other
agreement, instrument or obligation to which Buyer or any of its Subsidiaries is
a party or by which any of them or any of their properties or assets may be
bound, or (iii) conflict with, violate, or cause the termination of any permit,
concession, franchise, license, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to Buyer or any of its Subsidiaries or
any of its or their properties or assets, except in the case of (ii) and
(iii) for any such conflicts, violations, defaults, terminations, cancellations
or accelerations which are not, individually or in the aggregate, reasonably
likely to have a Buyer Material Adverse Effect.

    (c) No consent, approval, order or authorization of, or registration,
declaration or filing with, any Governmental Entity is required by or with
respect to Buyer or any of its Subsidiaries in connection with the execution and
delivery of this Agreement or the consummation of the transactions contemplated
hereby, except for (i) the filing of the pre-merger notification report under
the HSR Act, (ii) the filing of the Registration Statement with the SEC in
accordance with the Securities Act, (iii) the filing of the Certificate of
Merger with the New Jersey Treasurer, (iv) the filing of the Joint Proxy
Statement with the SEC in accordance with the Exchange Act, (v) such consents,
approvals, orders, authorizations, registrations, declarations and filings as
may be required under applicable state securities laws and the laws of any
foreign country, (vi) the approval by the Nasdaq National Market of the listing
of the shares of Buyer Common Stock to be issued in the transactions
contemplated by this Agreement, and (vii) such other consents, authorizations,
filings, approvals and registrations which, if not obtained or made, would not
interfere with the operation of any facility of Buyer or otherwise be reasonably
likely to have a Buyer Material Adverse Effect.

    SECTION 4.04 SEC FILINGS; FINANCIAL STATEMENTS.

    (a) Buyer has filed and made available to Seller all forms, reports and
documents required to be filed by Buyer with the SEC since January 1, 1996 other
than registration statements on Form S-8 (collectively, the "Buyer SEC
Reports"). The Buyer SEC Reports (i) at the time filed, complied in all material
respects with the applicable requirements of the Securities Act and the Exchange
Act, as the case may be, and (ii) did not at the time they were filed (or if
amended or superseded by a filing prior to the date of this Agreement, then on
the date of such filing) contain any untrue statement of a material fact or omit
to state a material fact required to be stated in such Buyer SEC Reports or
necessary in order to make the statements in such Buyer SEC Reports, in the
light of the circumstances under which they were made, not misleading. None of
Buyer's Subsidiaries is required to file any forms, reports or other documents
with the SEC.

    (b) Each of the consolidated financial statements (including, in each case,
any related notes) contained in the Buyer SEC Reports complied as to form in all
material respects with the applicable published rules and regulations of the SEC
with respect thereto, was prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
involved

                                      A-15
<PAGE>
(except as may be indicated in the notes to such financial statements or, in the
case of unaudited statements, as permitted by Form 10-Q of the SEC) and fairly
presented the consolidated financial position of Buyer and its Subsidiaries as
of the dates and the consolidated results of its operations and cash flows for
the periods indicated, except that the unaudited interim financial statements
were or are subject to normal and recurring year-end adjustments which were not
or are not expected to be material in amount. The unaudited balance sheet of
Buyer as of October 31, 1998 is referred to herein as the "Buyer Balance Sheet."

    SECTION 4.05 NO UNDISCLOSED LIABILITIES.  Except as disclosed in the Buyer
SEC Reports filed prior to the date hereof, and except for normal or recurring
liabilities incurred since October 31, 1998 in the ordinary course of business
consistent with past practices, Buyer and its Subsidiaries do not have any
liabilities, either accrued, contingent or otherwise (whether or not required to
be reflected in financial statements in accordance with generally accepted
accounting principles), and whether due or to become due, which individually or
in the aggregate, are reasonably likely to have a Buyer Material Adverse Effect.

    SECTION 4.06 ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed in
the Buyer SEC Reports filed prior to the date hereof, since the date of the
Buyer Balance Sheet, Buyer and its Subsidiaries have conducted their businesses
only in the ordinary course and in a manner consistent with past practice and,
since such date, there has not been (i) any change in the financial condition,
results of operations, business or properties of Buyer and its Subsidiaries,
taken as a whole, that has had, or is reasonably likely to have, a Buyer
Material Adverse Effect; (ii) any damage, destruction or loss (whether or not
covered by insurance) with respect to Buyer or any of its Subsidiaries having a
Buyer Material Adverse Effect; (iii) any material change by Buyer in its
accounting methods, principles or practices to which Seller has not previously
consented in writing; (iv) any revaluation by Buyer of any of its assets having
a Buyer Material Adverse Effect; or (v) any other action or event that would
have required the consent of Seller pursuant to Section 5.02 of this Agreement
had such action or event occurred after the date of this Agreement.

    SECTION 4.07 TAXES.

    (a) Buyer and each of its Subsidiaries have (i) filed all federal, state,
local and foreign Tax Returns required to be filed by them prior to the date of
this Agreement (taking into account extensions), (ii) paid or accrued all Taxes
due and payable, and (iii) paid or accrued all Taxes for which a notice of
assessment or collection has been received (other than amounts being contested
in good faith by appropriate proceedings), except in the case of clause (i),
(ii) or (iii) for any such filings, payments or accruals which are not
reasonably likely, individually or in the aggregate, to have a Buyer Material
Adverse Effect. The unpaid Taxes of the Buyer and each of its Subsidiaries for
tax periods through the Buyer Balance Sheet date do not exceed the accruals and
reserves for Taxes (excluding reserves for deferred Taxes) set forth on the
Buyer Balance Sheet by an amount that would have a Buyer Material Adverse
Effect. Neither the IRS nor any other taxing authority has asserted any claim
for Taxes, or to the actual knowledge of the executive officers of Buyer, is
threatening to assert any claims for Taxes, which claims, individually or in the
aggregate, are reasonably likely to have a Buyer Material Adverse Effect. Buyer
and each of its Subsidiaries have withheld or collected and paid over to the
appropriate governmental authorities (or are properly holding for such payment)
all Taxes required by law to be withheld or collected, except for amounts which
are not reasonably likely, individually or in the aggregate, to have a Buyer
Material Adverse Effect. There are no liens for Taxes upon the assets of Buyer
or any of its Subsidiaries (other than liens for taxes that are not yet due or
that are being contested in good faith by appropriate proceedings), except for
liens which are not reasonably likely, individually or in the aggregate, to have
a Buyer Material Adverse Effect.

    (b) Buyer is not and never has been a party to or bound by any Tax
indemnity, Tax sharing or Tax allocation agreement (whether written or unwritten
or arising under operation of federal law as a result

                                      A-16
<PAGE>
of being a member of a group filing consolidated or combined Tax Returns, under
operation of certain state laws as a result of being a member of a combined,
consolidated or unitary group, or under comparable laws of other states or
foreign jurisdictions) which includes a party other than Buyer and its
Subsidiaries nor does Buyer owe any amount under any such agreement.

    (c) Neither Buyer nor any of its Subsidiaries is a "consenting corporation"
within the meaning of Section 341(f) of the Code, and none of the assets of
Buyer or the Subsidiaries are subject to an election under Section 341(f) of the
Code.

    (d) Neither Buyer nor any of its Subsidiaries has been a United States real
property holding corporation with the meaning of Section 897(c)(2) of the Code
during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code.

    (e) Neither Buyer nor any of its Subsidiaries has made any payments, is
obligated to make any payments, or is a party to any agreement that could
obligate it to make any payments that will be an "excess parachute payment"
under Section 280G of the Code as a result of the transactions contemplated by
this Agreement.

    SECTION 4.08 PROPERTIES.

    (a) Buyer has provided to Seller a true and complete list of all Material
Leases of Buyer and its Subsidiaries and the location of the premises. With
respect to each Material Lease of Buyer: (i) the lease is legal, valid, binding,
enforceable and in full force and effect; (ii) the lease will continue to be
legal, valid, binding, enforceable against Buyer subject to the Bankruptcy and
Equity exception, and in full force and effect immediately following the Closing
in accordance with the terms thereof as in effect prior to the Closing;
(iii) neither Buyer nor, to the Buyer's knowledge, any other party to the lease
or sublease is in breach or default, and no event has occurred which, with
notice or lapse of time, would constitute a breach or default or permit
termination, modification or acceleration thereunder; and (iv) Buyer has not
assigned, transferred, conveyed, mortgaged, deeded in trust or encumbered any
interest in the leasehold or subleasehold; except, in the case of clauses
(i) through (iv) that the same is not reasonably likely to have a Seller
Material Adverse Effect.

    (b) Buyer has provided to Seller a true and complete list of all Owned Real
Property owned by Buyer and its Subsidiaries. With respect to any item of real
property owned by Buyer: (a) Buyer or the identified Subsidiary has good and
clear record and marketable title to such property, insurable by a recognized
national title insurance company at standard rates, free and clear of any
security interest, easement, covenant or other restriction, except for recorded
easements, covenants and other restrictions which do not materially impair the
current uses or occupancy of such property; (b) there are no (i) condemnation
proceedings pending or, to Buyer's knowledge, threatened relating to such parcel
or (ii) litigation or administrative actions pending or, to Buyer's knowledge,
threatened relating to such parcel; (c) the legal description for such parcel
contained in the deed thereof describes such parcel fully and adequately; the
buildings and improvements located thereon are located within the boundary lines
of the described parcels of land, are not in violation of current setback
requirements, zoning laws and ordinances and do not encroach on any easement
which may burden the land; the land does not serve any adjoining property for
any purpose inconsistent with the use of the land as heretofore used; and such
parcel is not subject to any restriction for which any permits or licenses
necessary to use thereof as heretofore used have not been obtained; (d) there
are no leases, subleases or agreements granting to any party or parties the
right of use or occupancy of any portion of such parcel; and (e) to Buyer's
knowledge, each parcel is an independent unit which does not rely on any
facilities (other than the facilities of public utility and water companies)
located on any other property (i) to fulfill any zoning, building code or other
municipal or governmental requirement; (ii) for structural support or the
furnishing of any essential building systems or utilities, including but not
limited to electric, plumbing, mechanical, heating, ventilating and air
conditioning systems; or (iii) to fulfill the requirements of any

                                      A-17
<PAGE>
lease. To Buyer's knowledge, no building or other improvement not included in
the parcel relies on any part of the parcel to fulfill any zoning, building code
or other municipal or governmental requirement or for structural support or the
furnishing of any essential building systems or utilities. Such parcel is
assessed by local property assessors as a tax parcel or parcels separate from
all other tax parcels.

    SECTION 4.09 AGREEMENTS, CONTRACTS AND COMMITMENTS.  Buyer has not breached,
or received in writing any claim or notice that it has breached, any of the
terms or conditions of any material agreement, contract or commitment filed as
an exhibit to the Buyer SEC Reports or any other agreement, contract or
commitment the termination of which would have a Buyer Material Adverse Effect
("Buyer Material Contracts") in such a manner as, individually or in the
aggregate, are reasonably likely to have a Buyer Material Adverse Effect. Each
Buyer Material Contract that has not expired by its terms is in full force and
effect, and no party to any of the Buyer Material Contracts will have the right
to terminate such contract as a result of the transactions contemplated by this
Agreement. None of the Buyer Material Contracts is currently being renegotiated,
and Buyer has no knowledge that any Buyer Material Contract will be subject of a
voluntary or regulatory ordered renegotiation within 12 months after the date of
this Agreement.

    SECTION 4.10 LITIGATION.  Except as described in the Buyer SEC Reports filed
prior to the date hereof, there is no action, suit or proceeding, claim,
arbitration or investigation against Buyer pending or as to which Buyer has
received any written notice of assertion, which, individually or in the
aggregate, is reasonably likely to have a Buyer Material Adverse Effect or a
material adverse effect on the ability of Buyer to consummate the transactions
contemplated by this Agreement.

    SECTION 4.11 ENVIRONMENTAL MATTERS.  Except as disclosed in the Buyer SEC
Reports filed prior to the date hereof and except for such matters that,
individually or in the aggregate, are not reasonably likely to have a Buyer
Material Adverse Effect: (i) Buyer and its Subsidiaries have complied and are
currently in compliance with all applicable Environmental Laws; (ii) the
properties currently owned or operated by Buyer and its Subsidiaries (including
soils, groundwater, surface water, buildings or other structures) are not
contaminated with any Hazardous Substances; (iii) the properties formerly owned
or operated by Buyer or any of its Subsidiaries were not contaminated with
Hazardous Substances during the period of ownership or operation by Buyer or any
of its Subsidiaries; (iv) neither Buyer nor its Subsidiaries are subject to
liability for any Hazardous Substance disposal or contamination on any third
party property; (v) neither Buyer nor any of its Subsidiaries has been
associated with any release or threat of release of any Hazardous Substance;
(vi) neither Buyer nor any of its Subsidiaries has received any notice, demand,
letter, claim or request for information alleging that Buyer or any of its
Subsidiaries may be in violation of or liable under any Environmental Law;
(vii) neither Buyer nor any of its Subsidiaries is subject to any orders,
decrees, injunctions or other arrangements with any Governmental Entity or is
subject to any indemnity or other agreement with any third party relating to
liability under any Environmental Law or relating to Hazardous Substances; and
(viii) there are no circumstances or conditions involving Buyer or any of its
Subsidiaries that could reasonably be expected to result in any claims,
liability, investigations, costs or restrictions on the ownership, use,

Environmental Law.

    SECTION 4.12 EMPLOYEE BENEFIT PLANS.

    (a) Buyer has listed in Section 4.12 of the Buyer Disclosure Schedule all
employee benefit plans (as defined in Section 3(3) of ERISA) and all bonus,
stock option, stock purchase, incentive, deferred compensation, supplemental
retirement, severance, welfare, fringe benefit and other similar employee
benefit plans, and all unexpired severance agreements, written or otherwise, for
the benefit of, or relating to, any current or former employee, director or
independent contractor providing services to Buyer, any Subsidiary of Buyer, or
any ERISA Affiliate of Buyer (together, the "Buyer Employee Plans"). With
respect to each Buyer Employee Plan, Buyer has made available to Seller, a true
and

                                      A-18
<PAGE>
correct copy of (i) the most recent annual report (Form 5500) filed with the IRS
(and the related financial statement), (ii) such Buyer Employee Plan,
(iii) each trust agreement and group annuity contract, if any, relating to such
Buyer Employee Plan and (iv) the most recent actuarial report or valuation
relating to a Buyer Employee Plan subject to Title IV of ERISA.

    (b) With respect to the Buyer Employee Plans, individually and in the
aggregate, no event has occurred, and to the knowledge of Buyer, there exists no
condition or set of circumstances in connection with which Buyer could be
subject to any liability that is reasonably likely to have a Buyer Material
Adverse Effect under ERISA, the Code or any other applicable law.

    (c) With respect to the Buyer Employee Plans, individually and in the
aggregate, there are no funded benefit obligations for which contributions have
not been made or properly accrued and there are no unfunded benefit obligations
which have not been accounted for by reserves, or otherwise properly footnoted
in accordance with generally accepted accounting principles, on the financial
statements of Buyer, which obligations are reasonably likely to have a Buyer
Material Adverse Effect.

    (d) There are no pending, or threatened claims, actions, suits, termination
proceedings, or investigations by any Governmental Entity, against or involving
any Buyer Benefit Plan; any Buyer Benefit Plan intended to be qualified under
Section 401(a) of the Code has received a determination letter from the Internal
Revenue Service to that effect, which has not been revoked, and nothing has
occurred since the date of the most recent determination letter that would
adversely affect such qualification.

    (e) Except as disclosed in Buyer SEC Reports filed prior to the date of this
Agreement, and except as provided for in this Agreement, neither Buyer nor any
of its Subsidiaries is a party to any oral or written (i) agreement with any
current or former officer or other key employee of Buyer or any of its
Subsidiaries, the benefits of which are contingent, or the terms of which are
materially altered, upon the occurrence of a transaction involving Buyer of the
nature contemplated by this Agreement, (ii) agreement with any current or former
officer of Buyer providing any term of employment or compensation guarantee
extending for a period longer than one year from the date hereof and for the
payment of compensation in excess of $100,000 per annum, or (iii) agreement or
plan, including any stock option plan, stock appreciation right plan, restricted
stock plan or stock purchase plan, any of the benefits of which will be
increased, or the vesting or funding of the benefits of which will be
accelerated, by the occurrence of any of the transactions contemplated by this
Agreement or the value of any of the benefits of which will be calculated on the
basis of any of the transactions contemplated by this Agreement.

    (f) At no time has the Buyer or any Subsidiary of Buyer been obligated to
contribute to any "multiemployer plan" (as defined in Section 4001 or ERISA).

    SECTION 4.13 COMPLIANCE WITH LAWS.  Buyer has complied with, is not in
violation of, and has not received any notices of violation with respect to, any
federal, state or local statute, law or regulation with respect to the conduct
of its business, or the ownership or operation of its business, except for
failures to comply or violations which, individually or in the aggregate, have
not had and are not reasonably likely to have a Buyer Material Adverse Effect.
No officer or director of Buyer or any of its Subsidiaries or holder of greater
than 5% of the outstanding capital stock of Buyer would disqualify Seller from
obtaining any permits necessary for the business of Seller or disqualify Buyer
or Seller from bidding on or being awarded any government contract.

    SECTION 4.14 ACCOUNTING AND TAX MATTERS.  To its knowledge, after consulting
with its independent auditors, neither Buyer nor any of its Affiliates has taken
or agreed to take any action which would (i) prevent Buyer from accounting for
the business combination to be effected by the Merger as a pooling of interests,
or (ii) prevent the Merger from constituting a transaction qualifying as a
reorganization under Section 368(a) of the Code.

                                      A-19

information in the Registration Statement (except for information supplied by
Seller for inclusion in the Registration Statement, as to which Buyer makes no
representation) shall not at the time the Registration Statement is declared
effective by the SEC contain any untrue statement of a material fact or omit to
state any material fact required to be stated in the Registration Statement or
necessary in order to make the statements in the Registration Statement, in
light of the circumstances under which they were made, not misleading. The
information (except for information supplied by Seller for inclusion in the
Joint Proxy Statement, as to which Buyer makes no representation) in the Joint
Proxy Statement shall not, on the date the Joint Proxy Statement is first mailed
to stockholders of Buyer or Seller, at the time of the Buyer Meeting and the
Seller Meeting and at the Effective Time, contain any statement which, at such
time and in light of the circumstances under which it shall be made, is false or
misleading with respect to any material fact, or omit to state any material fact
necessary in order to make the statements made in the Joint Proxy Statement not
false or misleading; or omit to state any material fact necessary to correct any
statement in any earlier communication with respect to the solicitation of
proxies for the Buyer Meeting or the Seller Meeting which has become false or
misleading. If at any time prior to the Effective Time any event relating to
Buyer or any of its Affiliates, officers or directors should be discovered by
Buyer which should be set forth in an amendment to the Registration Statement or
a supplement to the Joint Proxy Statement, Buyer shall promptly inform Seller.

    SECTION 4.16 LABOR MATTERS.  Neither Buyer nor any of its Subsidiaries is a
party to or otherwise bound by any collective bargaining agreement, contract or
other agreement or understanding with a labor union or labor organization, nor,
as of the date hereof, is Buyer or any of its Subsidiaries the subject of any
material proceeding asserting that Buyer or any of its Subsidiaries has
committed an unfair labor practice or is seeking to compel it to bargain with
any labor union or labor organization nor, as of the date of this Agreement, is
there pending or, to the knowledge of the executive officers of Buyer,

purpose of engaging in the transactions contemplated by this Agreement, has
engaged in no other business activities and has conducted its operations only as
contemplated by this Agreement.

    SECTION 4.19 NO SELLER STOCK.  Neither the Buyer nor any of its affiliates
or Subsidiaries directly or indirectly beneficially owns any Seller Common
Stock.

                                   ARTICLE V
                              CONDUCT OF BUSINESS

    SECTION 5.01 COVENANTS OF SELLER.  During the period from the date of this
Agreement and continuing until the earlier of the termination of this Agreement
or the Effective Time, Seller agrees as to itself and its respective
Subsidiaries (except to the extent that Buyer shall otherwise consent in
writing), to carry on its business in the usual, regular and ordinary course in
substantially the same manner as previously conducted, to pay its debts and
taxes when due subject to good faith disputes over such debts or taxes, to pay
or perform its other obligations when due, and, to the extent consistent with
such business, use all reasonable efforts consistent with past practices and
policies to preserve intact its present business organization, keep available
the services of its present officers and key employees and preserve its
relationships with customers, suppliers, distributors, and others having

                                      A-20
<PAGE>
business dealings with it. Except as expressly contemplated by this Agreement,
Seller shall not (and shall not permit any of its respective Subsidiaries to),

except as required by the terms of any employee stock plans or any related
agreements in effect as of the date of this Agreement;

    (b) Declare or pay any dividends on or make any other distributions (whether

party;

    (c) Issue, deliver or sell, or authorize or propose the issuance, delivery
or sale of, any shares of its capital stock or securities convertible into

whether by merger, consolidation, business combination, purchase of substantial
assets, tender offer or otherwise, whether for cash, securities or any other
consideration or combination thereof, other than the transactions contemplated
by this Agreement (any of the foregoing inquiries or proposals being referred to
in this Agreement as an "Acquisition Proposal"); provided, however, that if the
Board of Directors of Seller determines in good faith, based on the advice of
outside counsel, that failure to do so would be reasonably likely to constitute
a breach of its fiduciary duties to Seller's stockholders under applicable law,
Seller, in response to a written Acquisition Proposal that (i) was unsolicited
or that did not otherwise result from a breach of this section, and (ii) is more
favorable than the transaction contemplated by this Agreement (a "Superior
Proposal"), may (x) furnish non-public information with respect to Seller to the
person who made such Acquisition Proposal pursuant to a customary
confidentiality agreement and (y) participate in negotiations regarding such
Acquisition Proposal.

    The Board of Directors of Seller shall not (1) withdraw or modify, in a
manner adverse to Buyer, its approval or recommendation of this Agreement or the
Merger unless there is a Superior Proposal outstanding, (2) approve or
recommend, or propose to approve or recommend, an Acquisition Proposal that is
not a Superior Proposal or (3) cause Seller to enter into any letter of intent,
agreement in principle or other agreement with respect to an Acquisition
Proposal unless the Board of Directors of Seller shall have (x) determined in
good faith, based on the advice of outside counsel, that failure to do so would
be reasonably likely to constitute a breach of its fiduciary duties to Seller's
stockholders under applicable law, and (y) terminated this Agreement pursuant to
the termination provisions.

                                      A-24

advisors) of any Acquisition Proposal or any request for nonpublic information
in connection with an Acquisition Proposal or for access to the properties,
books or records of Seller by any person or entity that informs Seller that it
is considering making, or has made, an Acquisition Proposal. Such notice shall
be made orally and in writing and shall indicate in reasonable detail the
identity of the offeror and the terms and conditions of such proposal, inquiry

                          AGREEMENT AND PLAN OF MERGER

    The Agreement and Plan of Merger dated as of January 12, 1999 (the
"Agreement"), by and among Casella Waste Systems, Inc., a Delaware corporation
("Buyer"), Rutland Acquisition Sub, Inc., a New Jersey corporation and a direct,
wholly-owned subsidiary of Buyer ("Sub") and KTI, Inc., a New Jersey corporation
("Seller"), as amended by Amendment No. 1 to Agreement and Plan of Merger dated
May 12, 1999 ("Amendment No. 1") and by Amendment No. 2 to Agreement and Plan of
Merger dated September 8, 1999 ("Amendment No. 2"), is hereby amended as follows
as of this 23rd day of September, 1999. Capitalized terms not otherwise defined
herein shall have the meanings set forth in the Agreement.

1.  The sixth "WHEREAS" clause of the Agreement, which refers to the pooling of
    interests accounting of the Merger, is hereby deleted.

2.  Section 3.14 is hereby deleted, and the following shall be inserted in lieu
    thereof:

    "Section 3.14 Tax Matters. To its knowledge, after consulting with its legal
counsel, neither Seller nor any of its Affiliates (as defined in Section 6.10)
has taken or agreed to take any action which would prevent the Merger from
constituting a transaction qualifying as a reorganization under 368(a) of the
Code."

3.  Section 4.14 is hereby deleted, and the following shall be inserted in lieu
    thereof:

    "Section 4.14 Tax Matters. To its knowledge, after consulting with its legal
counsel, neither Buyer nor any of its Affiliates has taken or agreed to take any
action which would prevent the Merger from constituting a transaction qualifying
as a reorganization under 368(a) of the Code."

4.  Section 6.09 is hereby deleted, and the following shall be inserted in lieu
    thereof: "Intentionally omitted."

5.  Section 6.10 is hereby deleted, and the following shall be inserted in lieu
    thereof:

    'Section 6.10 Affiliate Agreements. Upon the execution of this Agreement,
Seller will provide Buyer with a list of those persons who are, in Seller's
reasonable judgment, "affiliates" of Seller within the meaning of Rule 145 (each
such person who is an "affiliate" of Seller within the meaning of Rule 145 is
referred to as an "Affiliate") promulgated under the Securities Act ("Rule
145"). Seller shall provide Buyer such information and documents as Buyer shall
reasonably request for purposes of reviewing such list and shall notify Buyer in
writing regarding any change in the identity of its Affiliates prior to the
Closing Date. Seller has delivered or caused to be delivered to Buyer, prior to
the execution of this Agreement, from each of its Affiliates, an executed
Affiliate Agreement, in substantially the form appended hereto as Exhibit C-3
(in the case of Seller Affiliates) (collectively, the "Affiliate Agreements").
Buyer shall be entitled to place appropriate legends on the certificates
evidencing any Buyer Common Stock to be received by such Affiliates of Seller
pursuant to the terms of this Agreement, and to issue appropriate stop transfer
instructions to the transfer agent for the Buyer Common Stock, consistent with
the terms of the Affiliate Agreements (provided that such legends or stop
transfer instructions shall be removed, two years after the Effective Date, upon
the request of any stockholder that is not then an Affiliate of Buyer). Seller
agrees that any Affiliate Agreements signed by affiliates of Buyer in connection
with the Agreement are hereby terminated.

6.  Section 7.01(f) is hereby deleted, and the following shall be inserted in
    lieu thereof: "Intentionally omitted."

expenses; provided, however, Seller and Buyer shall share equally all fees and
expenses, other than attorneys' fees, incurred with respect to the printing and
filing of the Joint Proxy Statement (including any related preliminary
materials) and the Registration Statement (including financial statements and
exhibits) and any amendments or supplements."

8.  In all other respects, the Agreement shall remain in full force and effect,
    and all references in the Agreement to "this Agreement" shall mean the
    Agreement as amended hereby.

PERSONAL AND CONFIDENTIAL

The Board of Directors
KTI, Inc.
7000 Boulevard East
Guttenberg, New Jersey 07093

Gentlemen:

You have asked CIBC World Markets Corp. ("CIBC World Markets") to render a
written opinion ("Fairness Opinion") to the Board of Directors as to the
fairness to the shareholders of KTI, Inc. ("KTI" or the "Company"), from a
financial point of view, of the Exchange Ratio (as defined below) provided for
in Amendment No. 2 (Amendment No. 2) to the Agreement and Plan of Merger (the
"Merger Agreement") by and among Casella Waste Systems, Inc. ("Casella"),
Rutland Acquisition, Inc. ("Newco"), a wholly owned subsidiary of Casella, and
KTI, pursuant to which Newco will be merged with and into KTI (the "Merger"). We
did not, at your request, participate in the negotiation of Amendment No. 1 to
the Merger Agreement ("Amendment No. 1"), Amendment No. 2 or the Merger
Agreement.

Pursuant to Amendment No. 2, each share of common stock of KTI will be converted
into the right to receive 0.51 shares of Class A Common Stock, $.01 par value
per share, of Casella (the "Exchange Ratio").

In arriving at our Fairness Opinion we: (i) reviewed the Merger Agreement,
Amendment No. 1 and Amendment No. 2; (ii) reviewed drafts of the Seller Stock
Option Agreement, Affiliate Agreements, Stockholder Voting Agreements and
Employment Agreements (together with the Merger Agreement, Amendment No. 1 and
Amendment No. 2, the "Transaction Agreements"); (iii) reviewed the historical
financial statements and financial forecasts and other information prepared by
representatives of KTI and Casella; (iv) reviewed certain publicly available
information for KTI and Casella, including periodic and other reports filed with
the Securities and Exchange Commission; (v) reviewed the reported market prices
and trading volumes for KTI and Casella shares; (vi) held discussions with the
senior management and representatives of KTI and Casella concerning each
company's historical and current operations, financial condition and prospects;
and (vii) reviewed such other documents and financial, economic and market
information and made such other investigations as we deemed appropriate for the
purposes of such opinion.

We have assumed that the Merger will be consummated upon the terms set forth in
the Merger Agreement, Amendment No. 1, and Amendment No. 2. We have further
assumed that the Merger will comply with applicable United States, foreign,
federal and state laws.

We also considered certain publicly available financial data for certain
companies we deemed comparable to KTI and Casella. We considered, to the extent
publicly available, the financial terms of certain business combinations that
have recently been effected in similar mergers and acquisitions. We performed
discounted cash flow analyses on the projections furnished to us by KTI and
Casella.

In rendering our Fairness Opinion we relied upon and assumed, without
independent verification or investigation, the accuracy and completeness of all
of the financial and other information provided to us or prepared by KTI and
Casella and their respective employees, representatives and affiliates. With

respect to forecasts of future financial condition and operating results of KTI
and Casella and estimates of the operating synergies achievable as a result of
the Merger provided to us, we assumed at the direction of each company's
management, without independent verification or investigation, that such
forecasts and estimates were reasonably prepared on bases reflecting the best
available information, estimates and judgement of each company's respective
management. We have neither made nor obtained any independent evaluations or
appraisals of the assets or the liabilities of KTI, Casella or other affiliated
entities. We have assumed, without independent verification, the accuracy of the
advice and conclusions of the parties' legal counsel and accountants with
respect to legal, accounting and tax matters. In this regard, we note that we
assume that the Merger will qualify for pooling-of-interests accounting
treatment in accordance with United States generally accepted accounting
principles and will qualify as a tax free reorganization under the Internal
Revenue Code of 1986, as amended. We have also assumed that obtaining any
necessary regulatory or third-party approvals for the Merger will not have an
adverse effect on KTI or Casella. We are not expressing any opinion as to the
underlying valuation, future performance or long term viability of KTI or
Casella following the Merger, or the price at which Casella common stock will
trade subsequent to the Merger. We express no opinion as to the actual number of
shares of Casella Class A Common Stock to be issued to the shareholders of KTI
in the Merger. Our opinion is necessarily based on the information available to
us and general economic, financial and stock market conditions and circumstances
as they exist and can be evaluated by us on the date hereof. It should be
understood that, although subsequent developments may affect this opinion, we do
not have any obligation to update, revise or reaffirm the opinion.

As part of our investment banking business, we are regularly engaged in
valuations of businesses and securities in connection with acquisitions and
mergers, underwritings, the secondary distributions of securities, private
placements and valuations for other purposes.

We were engaged to render this fairness opinion to the Board of Directors of KTI
and will receive a fee for our services. CIBC World Markets has also acted as
co-managing underwriter for Casella in prior financing transactions for which we
have received fees for our services. In the ordinary course of its business,
CIBC World Markets and its affiliates may actively trade securities of KTI and
Casella for their own account and for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.

Based upon, and subject to the foregoing, and such other factors as we deem
relevant, it is our opinion that, as of the date hereof, the Exchange Ratio set
forth in Amendment No. 2 is fair to the shareholders of KTI from a financial
point of view. Neither this Fairness Opinion nor the services provided by CIBC
World Markets in connection herewith may be publicly disclosed or referred to in
any manner by KTI without the prior written approval of CIBC World Markets. CIBC
World Markets consents to the inclusion of this opinion in its entirety and any
reference to this opinion in any prospectus, proxy statement or
solicitation/recommendation statement, as the case may be, required to be
distributed to the Company's shareholders in connection with the Merger.

                                           Very truly yours,

                                    [SIGNATURE]

Gentlemen:

Reference is made to our letter to you dated September 15, 1999 (the "Prior
Letter"). Capitalized terms used herein and not otherwise defined have the same
meaning as in the Prior Letter.

On September 23, 1999, we were advised that the Merger is anticipated to be
accounted for as a purchase transaction. Accordingly, at your request, we
reviewed the analyses performed in connection with our rendering the Prior
Letter.

Subject to the qualifications and limitations contained in the Prior Letter, we
reaffirm our conclusion stated therein.

                                           Very truly yours,

                                    [SIGNATURE]

    14A:11-1 RIGHT OF SHAREHOLDERS TO DISSENT.--(1) Any shareholder of a
domestic corporation shall have the right to dissent from any of the following
corporate actions

    (a) Any plan of merger or consolidation to which the corporation is a party,
provided that, unless the certificate of incorporation otherwise provides

    (i) a shareholder shall not have the right to dissent from any plan of
merger or consolidation with respect to shares

    (A) of a class or series which is listed on a national securities exchange
or is held of record by not less than 1,000 holders on the record date fixed to
determine the shareholders entitled to vote upon the plan of merger or
consolidation; or

    (B) for which, pursuant to the plan of merger or consolidation, he will

securities exchange or held of record by not less than 1,000 holders, or (z)
cash and such securities;

    (ii) a shareholder of a surviving corporation shall not have the right to
dissent from a plan of merger, if the merger did not require for its approval
the vote of such shareholders as provided in section 14A:10-5.1 or in
subsections 14A:10-3(4), 14A:10-7(2) or 14A:10-7(4); or

    (b) Any sale, lease, exchange or other disposition of all or substantially
all of the assets of a corporation not in the usual or regular course of
business as conducted by such corporation, other than a transfer pursuant to
subsection (4) of N.J.S. 14A:10-11, provided that, unless the certificate of
incorporation otherwise provides, the shareholder shall not have the right to

    (ii) from a transaction pursuant to a plan of dissolution of the corporation

dissent exists.

    (4) A corporation may provide in its certificate of incorporation that
holders of all its shares, or of a particular class or series thereof, shall
have the right to dissent from specified corporate actions in addition to those
enumerated in subsection 14A:11-1(1), in which case the exercise of such right
of dissent shall be governed by the provisions of this Chapter.
<PAGE>
    14A:11-2 NOTICE OF DISSENT; DEMAND FOR PAYMENT; ENDORSEMENT OF
CERTIFICATES.--(1) Whenever a vote is to be taken, either at a meeting of
shareholders or upon written consents in lieu of a meeting pursuant to section
14A:5-6, upon a proposed corporate action from which a shareholder may dissent
under section 14A:11-1, any shareholder electing to dissent from such action
shall file with the corporation before the taking of the vote of the
shareholders on such corporate action, or within the time specified in
paragraphs 14A:5-6(2)(b) or 14A:5-6(2)(c), as the case may be, if no meeting of
shareholders is to be held, a written notice of such dissent stating that he
intends to demand payment for his shares if the action is taken.

    (2) Within 10 days after the date on which such corporate action takes
effect, the corporation, or, in the case of a merger or consolidation, the
surviving or new corporation, shall given written notice of the effective date
of such corporate action, by certified mail to each shareholder who filed
written notice of dissent pursuant to subsection 14A:11-2(1), except any who
voted for or consented in writing to the proposed action.

    (3) Within 20 days after the mailing of such notice, any shareholder to whom
the corporation was required to give such notice and who has filed a written
notice of dissent pursuant to this section may make written demand on the
corporation, or, in the case of a merger or consolidation, on the surviving or
new corporation, for the payment of the fair value of his shares.

    (4) Whenever a corporation is to be merged pursuant to section 14A:10-5.1 or
subsection 14A:10-7(4) and shareholder approval is not required under
subsections 14A:10-5.1(5) and 14A:10-5.1(6), a shareholder who has the right to
dissent pursuant to section 14A:11-1 may, not later than 20 days after a copy or
summary of the plan of such merger and the statement required by subsection
14A:10-5.1(2) is mailed to such shareholder, make written demand on the
corporation or on the surviving corporation, for the payment of the fair value
of his shares.

    (5) Whenever all the shares, or all the shares of a class or series, are to
be acquired by another corporation pursuant to section 14A:10-9, a shareholder
of the corporation whose shares are to be acquired may, not later than 20 days
after the mailing of notice by the acquiring corporation pursuant to paragraph
14A:10-9(3)(b), make written demand on the acquiring corporation for the payment
of the fair value of his shares.

    (6) Not later than 20 days after demanding payment for his shares pursuant
to this section, the shareholder shall submit the certificate or certificates
representing his shares to the corporation upon which such demand has been made
for notation thereon that such demand has been made, whereupon such certificate
or certificates shall be returned to him. If shares represented by a certificate
on which notation has been made shall be transferred, each new certificate
issued therefor shall bear similar notation, together with the name of the
original dissenting holder of such shares, and a transferee of such shares shall
acquire by such transfer no rights in the corporation other than those which the
original dissenting shareholder had after making a demand for payment of the
fair value thereof.

    (7) Every notice or other communication required to be given or made by a
corporation to any shareholder pursuant to this Chapter shall inform such
shareholder of all dates prior to which action must be taken by such shareholder
in order to perfect his rights as a dissenting shareholder under this Chapter.

    14A:11-3 "DISSENTING SHAREHOLDER" DEFINED; DATE FOR DETERMINATION OF FAIR
VALUE.--(1) A shareholder who has made demand for the payment of his shares in
the manner prescribed by subsections 14A:11-2(3), 14A:11-2(4) or 14A:11-2(5) is
hereafter in this Chapter referred to as a "dissenting shareholder".

    (2) Upon making such demand, the dissenting shareholder shall cease to have
any of the rights of a shareholder except the right to be paid the fair value of
his shares and any other rights of a dissenting shareholder under this Chapter.

                                      C-2
<PAGE>
    (3) "Fair value" as used in this Chapter shall be determined

    (a) As of the day prior to the day of the meeting of shareholders at which
the proposed action was approved or as of the day prior to the day specified by
the corporation for the tabulation of consents to such action if no meeting of

corporation authorized the acquisition, or, if a shareholder vote was taken
pursuant to section 14A:10-12, as of the day provided in paragraph
14A:11-3(3)(a).

    In all cases, "fair value" shall exclude any appreciation or depreciation
resulting from the proposed action.

    14A:11-4 TERMINATION OF RIGHT OF SHAREHOLDER TO BE PAID THE FAIR VALUE OF
HIS SHARES.--(1) The right of a dissenting shareholder to be paid the fair value
of his shares under this Chapter shall cease if

    (a) he has failed to present his certificates for notation as provided by

sufficient cause shown, shall otherwise direct;

    (b) his demand for payment is withdrawn with the written consent of the
corporation;

    (c) the fair value of the shares is not agreed upon as provided in this
Chapter and no action for the determination of fair value by the Superior Court
is commenced within the time provided in this Chapter;

    (d) the Superior Court determines that the shareholder is not entitled to
payment for his shares;

    (e) the proposed corporate action is abandoned or rescinded; or

    (f) a court having jurisdiction permanently enjoins or sets aside the

dissenting shareholder as a shareholder shall be reinstated as of the date of
the making of a demand for payment pursuant to subsections 14A:11-2(3),
14A:11-2(4) or 14A:11-2(5) without prejudice to any corporate action which has
taken place during the interim period. In such event, he shall be entitled to
any intervening preemptive rights and the right to payment of any intervening
dividend or other distribution, or, if any such rights have expired or any such

at the election of the board, the fair value thereof in cash as of the time of
such expiration or completion.

not withdraw his demand for payment of the fair value of his shares without the
written consent of the corporation.

shareholder of any other right to which he might otherwise be entitled by virtue
of share ownership, except as provided in subsection 14A:11-4(2) and except that
this subsection shall not exclude the right of such dissenting shareholder to
bring or maintain an appropriate action to obtain relief on the ground that such
corporate action will be or is ultra vires, unlawful or fraudulent as to such
dissenting shareholder.

    14A:11-6 DETERMINATION OF FAIR VALUE BY AGREEMENT.--(1) Not later than 10
days after the expiration of the period within which such shareholders may make
written demand to be paid the fair value of their shares, the corporation upon
which such demand has been made pursuant to subsections 14A:11-2(3),
14A:11-2(4) or 14A:11-2(5) shall mail to each dissenting shareholder the balance
sheet and the surplus statement of the corporation whose shares he holds, as of
the latest available date which shall not be earlier than 12 months prior to the
making of such offer and a profit and loss statement or statements for not less
than a 12-month period ended on the date of such balance sheet or, if the
corporation was not in existence for such 12-month period, for the portion
thereof during which it was in existence. The corporation may accompany such
mailing with a written offer to pay each dissenting shareholder for his shares
at a specified price deemed by such corporation to be the fair value thereof.
Such offer shall be made at the same price per share to all dissenting
shareholders of the same class, or, if divided into series, of the same series.

    (2) If, not later than 30 days after the expiration of the 10-day period
limited by subsection 14A:11-6(1), the fair value of the shares is agreed upon
between any dissenting shareholder and the corporation, payment therefor shall
be made upon surrender of the certificate or certificates representing such
shares.

    14A:11-7 PROCEDURE ON FAILURE TO AGREE UPON FAIR VALUE; COMMENCEMENT OF
ACTION TO DETERMINE FAIR VALUE.--(1) If the fair value of the shares is not
agreed upon within the 30-day period limited by subsection 14A:11-6(2), the
dissenting shareholder may serve upon the corporation upon which such demand has
been made pursuant to subsections 14A:11-2(3), 14A:11-2(4) or 14A:11-2(5) a
written demand that it commence an action in the Superior Court for the
determination of the fair value of the shares. Such demand shall be served not
later than 30 days after the expiration of the 30-day period so limited and such
action shall be commenced by the corporation not later than 30 days after
receipt by the corporation of such demand, but nothing herein shall prevent the
corporation from commencing such action at any earlier time.

    (2) If a corporation fails to commence the action as provided in subsection
14A:11-7(1), a dissenting shareholder may do so in the name of the corporation,
not later than 60 days after the expiration of the time limited by subsection
14A:11-7(1) in which the corporation may commence such an action.

    14A:11-8 ACTION TO DETERMINE FAIR VALUE; JURISDICTION OF COURT; APPOINTMENT
OF APPRAISER.--In any action to determine the fair value of shares pursuant to
this Chapter:

    (a) The Superior Court shall have jurisdiction and may proceed in the action
in a summary manner or otherwise;

    (b) All dissenting shareholders, wherever residing, except those who have
agreed with the corporation upon the price to be paid for their shares, shall be
made parties thereto as an action against their shares quasi in rem;

    (c) The court in its discretion may appoint an appraiser to receive evidence
and report to the court on the question of fair value, who shall have such power
and authority as shall be specified in the order of his appointment; and

    (d) The court shall render judgment against the corporation and in favor of
each shareholder who is a party to the action for the amount of the fair value
of his shares.

    14A:11-9 JUDGMENT IN ACTION TO DETERMINE FAIR VALUE.--(1) A judgment for the
payment of the fair value of shares shall be payable upon surrender to the
corporation of the certificate or certificates representing such shares.

                                      C-4
<PAGE>
    (2) The judgment shall include an allowance for interest at such rate as the
court finds to be equitable, from the date of the dissenting shareholder's
demand for payment under subsections 14A:11-2(3), 14A:11-2(4) or 14A:11-2(5) to
the day of payment. If the court finds that the refusal of any dissenting
shareholder to accept any offer of payment, made by the corporation under
section 14A:11-6, was arbitrary, vexatious or otherwise not in good faith, no
interest shall be allowed to him.

    14A:11-10 COSTS AND EXPENSES OF ACTION.--The costs and expenses of bringing
an action pursuant to section 14A:11-8 shall be determined by the court and
shall be apportioned and assessed as the court may find equitable upon the
parties or any of them. Such expenses shall include reasonable compensation for
and reasonable expenses of the appraiser, if any, but shall exclude the fees and
expenses of counsel for and experts employed by any party; but if the court
finds that the offer of payment made by the corporation under section 14A:11-6
was not made in good faith, or if no such offer was made, the court in its
discretion may award to any dissenting shareholder who is a party to the action
reasonable fees and expenses of his counsel and of any experts employed by the
dissenting shareholder.

    14A:11-11 DISPOSITION OF SHARES ACQUIRED BY CORPORATION.--(1) The shares of
a dissenting shareholder in a transaction described in subsection
14A:11-1(1) shall become reacquired by the corporation which issued them or by
the surviving corporation, as the case may be, upon the payment of the fair
value of shares.

    (2) (Deleted by amendment, P.L. 1995, c.279.)

    (3) In an acquisition of shares pursuant to section 14A:10-9 or section
14A:10-13, the shares of a dissenting shareholder shall become the property of
the acquiring corporation upon the payment by the acquiring corporation of the
fair value of such shares. Such payment may be made, with the consent of the
acquiring corporation, by the corporation which issued the shares, in which case
the shares so paid for shall become reacquired by the corporation which issued
them and shall be cancelled.

                              AMENDED AND RESTATED
                           1997 STOCK INCENTIVE PLAN

1. PURPOSE

    The purpose of this Amended and Restated 1997 Stock Incentive Plan (the
"Plan") of Casella Waste Systems, Inc., a Delaware corporation (the "Company"),
is to advance the interests of the Company's stockholders by enhancing the
Company's ability to attract, retain and motivate persons who make (or are
expected to make) important contributions to the Company by providing such
persons with equity ownership opportunities and performance-based incentives and
thereby better aligning the interests of such persons with those of the
Company's stockholders. Except where the context otherwise requires, the term
"Company" shall include any present or future subsidiary corporations of Casella
Waste Systems, Inc. as defined in Section 424(f) of the Internal Revenue Code of
1986, as amended, and any regulations promulgated thereunder (the "Code").

2. ELIGIBILITY

    All of the Company's employees, officers, directors, consultants and
advisors are eligible to be granted options, restricted stock, or other
stock-based awards (each, an "Award") under the Plan. Any person who has been
granted an Award under the Plan shall be deemed a "Participant".

3. ADMINISTRATION, DELEGATION

    (a) ADMINISTRATION BY BOARD OF DIRECTORS. The Plan will be administered by
the Board of Directors of the Company (the "Board"). The Board shall have
authority to grant Awards and to adopt, amend and repeal such administrative
rules, guidelines and practices relating to the Plan as it shall deem advisable.
The Board may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem expedient to carry the Plan into effect and it shall be the sole and final
judge of such expediency. All decisions by the Board shall be made in the
Board's sole discretion and shall be final and binding on all persons having or
claiming any interest in the Plan or in any Award. No director or person acting
pursuant to the authority delegated by the Board shall be liable for any action
or determination relating to or under the Plan made in good faith.

    (b) DELEGATION TO EXECUTIVE OFFICERS. To the extent permitted by applicable
law, the Board may delegate to one or more executive officers of the Company the
power to make Awards and exercise such other powers under the Plan as the Board
may determine, provided that the Board shall fix the maximum number of shares
subject to Awards and the maximum number of shares for any one Participant to be
made by such executive officers.

    (c) APPOINTMENT OF COMMITTEES. To the extent permitted by applicable law,
the Board may delegate any or all of its powers under the Plan to one or more
committees or subcommittees of the Board (a "Committee"). If and when the Class
A Common Stock, $.01 par value per share, of the Company (the "Common Stock") is
registered under the Securities Exchange Act of 1934 (the "Exchange Act"), the
Board shall appoint one such Committee of not less than two members, each member
of which shall be an "outside director" within the meaning of Section 162(m) of
the Code and a "non-employee director" as defined in Rule 16b-3 promulgated
under the Exchange Act." All references in the Plan to the "Board" shall mean
the Board or a Committee of the Board or the executive officer referred to in
Section 3(b) to the extent that the Board's powers or authority under the Plan
have been delegated to such Committee or executive officer.

                                     D-1-1

4. STOCK AVAILABLE FOR AWARDS

    (a) NUMBER OF SHARES. Subject to adjustment under Section 4(c), Awards may
be made under the Plan for up to such number of shares of Common Stock as is
equal to the sum of (i) 4,308,500 shares of Common Stock, plus (ii) such
additional number of shares of Common Stock as is equal to the aggregate number
of shares subject to Awards granted under the Company's 1993 Incentive Stock
Option Plan, 1994 Nonstatutory Stock Option Plan and 1996 Stock Option Plan
which are not actually issued because such Awards expire or otherwise result in
shares not being issued. If any Award expires or is terminated, surrendered or
canceled without having been fully exercised or is forfeited in whole or in part
or results in any Common Stock not being issued, the unused Common Stock covered
by such Award shall again be available for the grant of Awards under the Plan,
subject, however, in the case of Incentive Stock Options (as hereinafter
defined), to any limitation required under the Code. Shares issued under the
Plan may consist in whole or in part of authorized but unissued shares or
treasury shares.

    (b) PER-PARTICIPANT LIMIT. Subject to adjustment under Section 4(c), for
Awards granted after the Common Stock is registered under the Exchange Act, the
maximum number of shares with respect to which an Award may be granted to any
Participant under the Plan shall be 200,000 per calendar year. The
per-participant limit described in this Section 4(b) shall be construed and
applied consistently with Section 162(m) of the Code.

    (c) ADJUSTMENT TO COMMON STOCK. In the event of any stock split, stock
dividend, recapitalization, reorganization, merger, consolidation, combination,
exchange of shares, liquidation, spin-off or other similar change in
capitalization or event, or any distribution to holders of Common Stock other
than a normal cash dividend, (i) the number and class of securities available
under this Plan, (ii) the number and class of security and exercise price per
share subject to each outstanding Option, (iii) the repurchase price per
security subject to each outstanding Restricted Stock Award, and (iv) the terms
of each other outstanding stock-based Award shall be appropriately adjusted by
the Company (or substituted Awards may be made, if applicable) to the extent the
Board shall determine, in good faith, that such an adjustment (or substitution)
is necessary and appropriate. If this Section 4(c) applies and Section
8(e)(1) also applies to any event, Section 8(e)(1) shall be applicable to such
event, and this Section 4(c) shall not be applicable.

5. STOCK OPTIONS

    (a) GENERAL. The Board may grant options to purchase Common Stock (each, an
"Option") and determine the number of shares of Common Stock to be covered by
each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option".

    (b) INCENTIVE STOCK OPTIONS. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to a Participant, or any
other party, if an Option (or any part thereof) which is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

    (c) EXERCISE PRICE. The Board shall establish the exercise price at the time
each Option is granted and specify it in the applicable option agreement;
provided, however, that no Options will be granted at an exercise price which is
below the fair market value of the Common Stock covered thereby.

                                     D-1-2
<PAGE>
    (d) DURATION OF OPTIONS. Each Option shall be exercisable at such times and
subject to such terms and conditions as the Board may specify in the applicable
option agreement; provided, however, that no option shall be exercisable more
than ten years after the date of grant thereof.

    (e) EXERCISE OF OPTION. Options may be exercised only by delivery to the
Company of a written notice of exercise signed by the proper person together
with payment in full as specified in Section 5(f) for the number of shares for
which the Option is exercised.

    (f) PAYMENT UPON EXERCISE. Common Stock purchased upon the exercise of an
Option granted under the Plan shall be paid for as follows:

       (1) in cash or by check, payable to the order of the Company;

       (2) except as the Board may otherwise provide in an Option Agreement, (i)
       by delivery of an irrevocable and unconditional undertaking by a
       creditworthy broker to deliver promptly to the Company sufficient funds
       to pay the exercise price, or delivery by the Participant to the Company
       of a copy of irrevocable and unconditional instructions to a creditworthy
       broker to deliver promptly to the Company cash or a check sufficient to
       pay the exercise price, or (ii) by delivery of shares of Common Stock
       owned by the Participant valued at their fair market value as determined
       by the Board in good faith ("Fair Market Value"), which Common Stock was
       owned by the Participant at least six months prior to such delivery;

       (3) to the extent permitted by the Board and explicitly provided in an
       Option Agreement (i) by delivery of a promissory note of the Participant
       to the Company on terms determined by the Board, or (ii) by payment of
       such other lawful consideration as the Board may determine; or

       (4) any combination of the above permitted forms of payment.

6. RESTRICTED STOCK

    (a) GRANTS. The Board may grant Awards entitling recipients to acquire
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, "Restricted Stock Award").

    (b) TERMS AND CONDITIONS. The Board shall determine the terms and conditions
of any such Restricted Stock Award, including the conditions for repurchase (or
forfeiture) and the issue price, if any. Any stock certificates issued in
respect of a Restricted Stock Award shall be registered in the name of the
Participant and, unless otherwise determined by the Board, deposited by the
Participant, together with a stock power endorsed in blank, with the Company (or
its designee). At the expiration of the applicable restriction periods, the
Company (or such designee) shall deliver the certificates no longer subject to
such restrictions to the Participant or if the Participant has died, to the
beneficiary designated, in a manner determined by the Board, by a Participant to
receive amounts due or exercise rights of the Participant in the event of the
Participant's death (the "Designated Beneficiary"). In the absence of an
effective designation by a Participant, Designated Beneficiary shall mean the
Participant's estate.

7. OTHER STOCK-BASED AWARDS

    The Board shall have the right to grant other Awards based upon the Common
Stock having such terms and conditions as the Board may determine, including the
grant of shares based upon certain conditions, the grant of securities
convertible into Common Stock and the grant of stock appreciation rights.

                                     D-1-3
<PAGE>
8. GENERAL PROVISIONS APPLICABLE TO AWARDS

    (a) TRANSFERABILITY OF AWARDS. Except as the Board may otherwise determine
or provide in an Award, Awards shall not be sold, assigned, transferred, pledged
or otherwise encumbered by the person to whom they are granted, either
voluntarily or by operation of law, except by will or the laws of descent and
distribution, and, during the life of the Participant, shall be exercisable only
by the Participant. References to a Participant, to the extent relevant in the
context, shall include references to authorized transferees.

    (b) DOCUMENTATION. Each Award under the Plan shall be evidenced by a written
instrument in such form as the Board shall determine. Each Award may contain
terms and conditions in addition to those set forth in the Plan.

    (c) BOARD DISCRETION. Except as otherwise provided by the Plan, each type of
Award may be made alone or in addition or in relation to any other type of
Award. The terms of each type of Award need not be identical, and the Board need
not treat Participants uniformly.

    (d) TERMINATION OF STATUS. The Board shall determine the effect on an Award
of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

    (e) ACQUISITION EVENTS

       (1) CONSEQUENCES OF ACQUISITION EVENTS. Upon the occurrence of an
       Acquisition Event (as defined below), or the execution by the Company of
       any agreement with respect to an Acquisition Event, the Board shall
       provide that outstanding Options shall be assumed, or equivalent Options
       shall be substituted, by the acquiring or succeeding corporation (or an
       affiliate thereof), provided that any such Options substituted for
       Incentive Stock Options shall satisfy, in the determination of the Board,
       the requirements of Section 424(a) of the Code; provided, however, that
       in the event the acquiring or succeeding corporation does not agree to
       assume all such Options or other Awards, the Board shall take any one or
       more of the following actions with respect to then outstanding Options or
       other Awards not so assumed: (i) upon written notice to the Participants,
       provide that all then unexercised Options will become exercisable in full
       as of a specified time (the "Acceleration Time") prior to the Acquisition
       Event and will terminate immediately prior to the consummation of such
       Acquisition Event, except to the extent exercised by the Participants
       between the Acceleration Time and the consummation of such Acquisition
       Event; (ii) in the event of an Acquisition Event under the terms of which
       holders of Common Stock will receive upon consummation thereof a cash
       payment for each share of Common Stock surrendered pursuant to such
       Acquisition Event (the "Acquisition Price"), provide that all outstanding
       Options shall terminate upon consummation of such Acquisition Event and
       each Participant shall receive, in exchange therefor, a cash payment
       equal to the amount (if any) by which (A) the Acquisition Price
       multiplied by the number of shares of Common Stock subject to such
       outstanding Options (whether or not then exercisable), exceeds (B) the
       aggregate exercise price of such Options; (iii) provide that all
       Restricted Stock Awards then outstanding shall become free of all
       restrictions prior to the consummation of the Acquisition Event; and
       (iv) provide that any other stock-based Awards outstanding (A) shall
       become exercisable, realizable or vested in full, or shall be free of all
       conditions or restrictions, as applicable to each such Award, prior to
       the consummation of the Acquisition Event, or (B), if applicable, shall
       be assumed, or equivalent Awards shall be substituted, by the acquiring
       or succeeding corporation (or an affiliate thereof).

                                     D-1-4
<PAGE>
    An "Acquisition Event" shall mean: (a) any merger or consolidation which
results in the voting securities of the Company outstanding immediately prior
thereto representing immediately thereafter (either by remaining outstanding or
by being converted into voting securities of the surviving or acquiring entity)
less than 50% of the combined voting power of the voting securities of the
Company or such surviving or acquiring entity outstanding immediately after such
merger or consolidation; (b) any sale of all or substantially all of the assets
of the Company; or (c) the complete liquidation of the Company.

       (2) ASSUMPTION OF OPTIONS UPON CERTAIN EVENTS. The Board may grant Awards
       under the Plan in substitution for stock and stock-based awards held by
       employees of another corporation who become employees of the Company as a
       result of a merger or consolidation of the employing corporation with the
       Company or the acquisition by the Company of property or stock of the
       employing corporation. The substitute Awards shall be granted on such
       terms and conditions as the Board considers appropriate in the
       circumstances.

    (f) WITHHOLDING. Each Participant shall pay to the Company, or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. The Board may allow Participants to
satisfy such tax obligations in whole or in part in shares of Common Stock,
including shares retained from the Award creating the tax obligation, valued at
their Fair Market Value. The Company may, to the extent permitted by law, deduct
any such tax obligations from any payment of any kind otherwise due to a
Participant.

    (g) AMENDMENT OF AWARD. The Board may amend, modify or terminate any
outstanding Award, including but not limited to, substituting therefor another
Award of the same or a different type, changing the date of exercise or
realization, and converting an Incentive Stock Option to a Nonstatutory Stock
Option, provided that the Participant's consent to such action shall be required
unless the Board determines that the action, taking into account any related
action, would not materially and adversely affect the Participant.

    (h) CONDITIONS ON DELIVERY OF STOCK. The Company will not be obligated to
deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Award have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed and
delivered to the Company such representations or agreements as the Company may
consider appropriate to satisfy the requirements of any applicable laws,
rules or regulations.

    (i) ACCELERATION. The Board may at any time provide that any Options shall
become immediately exercisable in full or in part, that any Restricted Stock
Awards shall be free of all restrictions or that any other stock-based Awards
may become exercisable in full or in part or free of some or all restrictions or
conditions, or otherwise realizable in full or in part, as the case may be.

9. MISCELLANEOUS

    (a) NO RIGHT TO EMPLOYMENT OR OTHER STATUS. No person shall have any claim
or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any

              AMENDED 1997 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

1. PURPOSE.

    The purpose of this Amended 1997 Non-Employee Director Stock Option Plan
(the "Plan") of Casella Waste Systems, Inc. (the "Company") is to encourage
ownership in the Company by non-employee directors of the Company whose
continued services are considered essential to the Company's future progress and
to provide them with a further incentive to remain as directors of the Company.

2. ADMINISTRATION.

    The Board of Directors shall supervise and administer the Plan. Grants of
stock options under the Plan and the amount and nature of the awards to be
granted shall be automatic in accordance with Section 5. However, all questions
concerning interpretation of the Plan or any options granted under it shall be
resolved by the Board of Directors and such resolution shall be final and
binding upon all persons having an interest in the Plan. The Board of Directors
may, to the full extent permitted by or consistent with applicable laws or
regulations, delegate any or all of its powers under the Plan to a committee
appointed by the Board of Directors, and if a committee is so appointed, all
references to the Board of Directors in the Plan shall mean and relate to such
committee.

3. PARTICIPATION IN THE PLAN.

    Directors of the Company who are not employees of the Company or any
subsidiary of the Company ("non-employee directors") shall be eligible to
receive options under the Plan.

4. STOCK SUBJECT TO THE PLAN.

    (a)  The maximum number of shares of the Company's Class A Common Stock, par
value $.01 per share ("Common Stock"), which may be issued under the Plan shall
be 100,000 shares, subject to adjustment as provided in Section 7.

    (b)  If any outstanding option under the Plan for any reason expires or is
terminated without having been exercised in full, the shares covered by the
unexercised portion of such option shall again become available for issuance
pursuant to the Plan.

    (c)  All options granted under the Plan shall be non-statutory options not
entitled to special tax treatment under Section 422 of the Internal Revenue Code
of 1986, as amended (the "Code").

    (d)  Shares issued under the Plan may consist in whole or in part of
authorized but unissued shares or treasury shares.

5. TERMS, CONDITIONS AND FORM OF OPTIONS.

    Each option granted under the Plan shall be evidenced by a written agreement
in such form as the Board of Directors shall from time to time approve, which
agreements shall comply with and be subject to the following terms and
conditions:

    (a) OPTION GRANT DATES. Options shall automatically be granted to all
non-employee directors as follows:

        (i) each person who first becomes a non-employee director after the
    closing date (the "Closing Date") of the Company's initial public offering
    of Common Stock pursuant to an effective registration statement under the
    Securities Act of 1933, as amended, shall be granted an

                                     D-2-1
<PAGE>
    option to purchase 7,500 shares of Common Stock on the date of his or her
    initial election to the Board of Directors; and

        (ii) each non-employee director shall be granted an option to purchase
    7,500 shares of Common Stock on the date of each Annual Meeting of
    Stockholders of the Company commencing with the 1998 Annual Meeting of
    Stockholders (other than a director who was initially elected to the Board
    of Directors at any such Annual Meeting or, if previously, at any time after
    the prior year's Annual Meeting of Stockholders), provided that he or she is
    serving as a director immediately following such Annual Meeting.

    (b) OPTION EXERCISE PRICE. The option exercise price per share for each
option granted under the Plan shall equal (i) the last reported sales price per
share of the Company's Common Stock on the Nasdaq National Market (or if the
Common Stock is traded on a national securities exchange on the date of grant,
the reported closing sales price per share of the Company's Common Stock on such
exchange) on the date of grant (or if no such price is reported on such date
such price as reported on the nearest preceding day) or (ii) if the Common Stock
is not traded on the Nasdaq National Market or a national securities exchange,
the fair market value per share on the date of grant as most recently determined
by the Board of Directors.

    (c) TRANSFERABILITY OF OPTIONS. Except as the Board may otherwise determine
or provide in an option granted under the Plan, any option granted under the
Plan to an optionee shall not be transferable by the optionee other than by will
or the laws of descent and distribution or pursuant to a qualified domestic
relations order as defined by the Code or Title I of the Employee Retirement
Income Security Act, or the rules thereunder, and shall be exercisable during
the optionee's lifetime only by the optionee or the optionee's guardian or legal
representative. References to an optionee, to the extent relevant in the
context, shall include references to authorized transferees.

    (d) Vesting Period.

        (i) GENERAL. Each option granted under the Plan shall become exercisable
    in three equal annual installments beginning on the first anniversary of the
    Option Grant Date; provided, however, that the optionee has continued to
    serve as a director until at least the Annual Meeting of Stockholders
    immediately preceding such vesting date.

        (ii) ACCELERATION UPON CHANGE IN CONTROL. Notwithstanding the foregoing,
    each outstanding option granted under the Plan shall immediately become
    exercisable in full in the event a Change in Control (as defined in Section
    8) of the Company occurs.

    (e) TERMINATION. Each option shall terminate, and may no longer be
exercised, on the earlier of the (i) the date ten years after the grant date of
such option or (ii) the date 90 days after the optionee ceases to serve as a
director of the Company; provided that, in the event an optionee ceases to serve
as a director due to his or her death or disability (within the meaning of
Section 22(e)(3) of the Code or any successor provision), then the exercisable
portion of the option may be exercised, within the period of 180 days following
the date the optionee ceases to serve as a director (but in no event later than
ten years after the Option Grant Date), by the optionee or by the person to whom
the option is transferred in accordance with the terms of this Plan and the
applicable option agreement, or by written notice pursuant to Section 5(g).

    (f) EXERCISE PROCEDURE. An option may be exercised only by written notice to
the Company at its principal office accompanied by (i) payment in cash or by
certified or bank check of the full consideration for the shares as to which
they are exercised, (ii) delivery of outstanding shares of Common Stock (which,
in the case of shares acquired from the Company, have been outstanding for at
least six months) having a fair market value on the last business day preceding
the date of exercise equal to the option exercise price, or (iii) an irrevocable
undertaking by a broker (who is a member of the New York Stock Exchange) to
deliver promptly to the Company sufficient funds to pay the exercise

                                     D-2-2
<PAGE>
price or delivery of irrevocable instructions to a broker (who is a member of
the New York Stock Exchange) to deliver promptly to the Company cash or a check
sufficient to pay the exercise price.

    (g) EXERCISE BY REPRESENTATIVE FOLLOWING DEATH OF DIRECTOR. An optionee, by
written notice to the Company, may designate one or more persons (and from time
to time change such designation), including his or her legal representative,
who, by reason of the optionee's death, shall acquire the right to exercise all
or a portion of the option. If the person or persons so designated wish to
exercise any portion of the option, they must do so within the term of the
option as provided herein. Any exercise by a representative shall be subject to
the provisions of the Plan.

6. LIMITATION OF RIGHTS.

    (a) NO RIGHT TO CONTINUE AS A DIRECTOR. Neither the Plan, nor the granting
of an option nor any other action taken pursuant to the Plan, shall constitute
or be evidence of any agreement or understanding, express or implied, that the
Company will retain the optionee as a director for any period of time.

    (b) NO STOCKHOLDERS' RIGHTS FOR OPTIONS. An optionee shall have no rights as
a stockholder with respect to the shares covered by his or her option until the
date of the issuance to him or her of a stock certificate therefor, and no
adjustment will be made for dividends or other rights (except as provided in
Section 7) for which the record date is prior to the date such certificate is
issued.

    (c) COMPLIANCE WITH SECURITIES LAWS. Each option shall be subject to the
requirement that if, at any time, counsel to the Company shall determine that
the listing, registration or qualification of the shares subject to such option
upon any securities exchange or under any state or federal law, or the consent
or approval of any governmental or regulatory body, or the disclosure of
non-public information or the satisfaction of any other condition is necessary
as a condition of, or in connection with, the issuance or purchase of shares
thereunder, such option may not be exercised, in whole or in part, unless such
listing, registration, qualification, consent or approval, or satisfaction of
such condition shall have been effected or obtained on conditions acceptable to
the Board of Directors. Nothing herein shall be deemed to require the Company to
apply for or to obtain such listing, registration or qualification, or to
satisfy such condition.

7. ADJUSTMENT PROVISIONS FOR MERGERS, RECAPITALIZATIONS AND RELATED
TRANSACTIONS.

    If, through or as a result of any merger, consolidation, reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split, or other similar transaction, (i) the outstanding shares of Common Stock
are exchanged for a different number or kind of securities of the Company or of
another entity, or (ii) additional shares or new or different shares or other
securities of the Company or of another entity are distributed with respect to
such shares of Common Stock, the Board of Directors shall make an appropriate
and proportionate adjustment in (x) the maximum number and kind of shares
reserved for issuance under the Plan, (y) the number and kind of shares or other
securities subject to then outstanding options under the Plan, and (z) the price
for each share subject to any then outstanding options under the Plan (without
changing the aggregate purchase price for such options), to the end that each
option shall be exercisable, for the same aggregate exercise price, for such
securities as such optionholder would have held immediately following such event
if he had exercised such option immediately prior to such event. No fractional
shares will be issued under the Plan on account of any such adjustments.

8. CHANGE IN CONTROL.

    For purposes of the Plan, a "Change in Control" shall be deemed to have
occurred only if any of the following events occurs: (i) any "person", as such
term is used in Sections 13(d) and 14(d) of the Exchange Act (other than the
Company, any trustee or other fiduciary holding securities under an

                                     D-2-3
<PAGE>
employee benefit plan of the Company, or any corporation owned directly or
indirectly by the stockholders of the Company in substantially the same
proportion as their ownership of stock of the Company), is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of the Company (other than by virtue of ownership
of the Company's Class B Common Stock) representing 50% or more of the combined
voting power of the Company's then outstanding securities; (ii) the stockholders
of the Company approve a merger or consolidation of the Company with any other
corporation, other than a merger or consolidation which would result in the
voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity) more than 50% of the combined
voting power of the voting securities of the Company or such surviving entity
outstanding immediately after such merger or consolidation; (iii) the
stockholders of the Company approve a plan of complete liquidation of the
Company or an agreement for the sale or disposition by the Company of all or
substantially all of the Company's assets; or (iv) individuals who, on the date
on which the Plan was adopted by the Board of Directors, constituted the Board
of Directors of the Company, together with any new director whose election by
the Board of Directors or nomination for election by the Company's stockholders
was approved by a vote of at least a majority of the directors then still in
office who were directors on the date on which the Plan was adopted by the Board
of Directors or whose election or nomination was previously so approved (except
for any individual whose election as a director occurs as a result of an actual
or threatened election contest with respect to the election or removal of
directors or other actual or threatened solicitation of proxies or consents by
or on behalf of a person other than the Board of Directors), cease for any
reason to constitute at least a majority of the Board of Directors.

9. TERMINATION AND AMENDMENT OF THE PLAN.

    The Board of Directors may suspend or terminate the Plan or amend it in any
respect whatsoever.

10. NOTICE.

    Any written notice to the Company required by any of the provisions of the
Plan shall be addressed to the Treasurer of the Company and shall become
effective when it is received.

11. GOVERNING LAW.

    The Plan and all determinations made and actions taken pursuant hereto shall
be governed by the internal laws of the State of Delaware (without regard to any
applicable conflicts of laws or principles).

12. EFFECTIVE DATE.

    The Plan shall become effective on the Closing Date.

                                          subject
                                          to the plan and options automatically

                              AMENDED AND RESTATED
                       1997 EMPLOYEE STOCK PURCHASE PLAN

    The purpose of this Plan is to provide eligible employees of Casella Waste
Systems, Inc. (the "Company") and certain of its subsidiaries with opportunities
to purchase shares of the Company's Class A Common Stock, $0.01 par value (the
"Common Stock"), commencing on January 9, 1998. Six Hundred Thousand (600,000)
shares of Common Stock in the aggregate have been approved for this purpose.

    1.  ADMINISTRATION. The Plan will be administered by the Company's Board of
       Directors (the "Board") or by a Committee appointed by the Board (the
       "Committee"). The Board or the Committee has authority to make rules and
       regulations for the administration of the Plan and its interpretation and
       decisions with regard thereto shall be final and conclusive.

    2.  ELIGIBILITY. Participation in the Plan will neither be permitted nor
       denied contrary to the requirements of Section 423 of the Internal
       Revenue Code of 1986, as amended (the "Code"), and regulations
       promulgated thereunder. All employees of the Company, including Directors
       who are employees, and all employees of any subsidiary of the Company (as
       defined in Section 424(f) of the Code) designated by the Board or the
       Committee from time to time (a "Designated Subsidiary"), are eligible to
       participate in any one or more of the offerings of Options (as defined in
       Section 9) to purchase Common Stock under the Plan provided that:

       a. they are customarily employed by the Company or a Designated
       Subsidiary for more than 20 hours a week and for more than five months in
       a calendar year; and

       b. they have been employed by the Company or a Designated Subsidiary for
       at least six months prior to enrolling in the Plan; and

       c. they are employees of the Company or a Designated Subsidiary on the
       first day of the applicable Plan Period (as defined below).

    No employee may be granted an option hereunder if such employee, immediately
after the option is granted, owns 5% or more of the total combined voting power
or value of the stock of the Company or any subsidiary. For purposes of the
preceding sentence, the attribution rules of Section 424(d) of the Code shall
apply in determining the stock ownership of an employee, and all stock which the
employee has a contractual right to purchase shall be treated as stock owned by
the employee.

    3.  OFFERINGS. The Company will make one or more offerings ("Offerings") to
       employees to purchase Common Stock under this Plan. The first Offering
       will begin on January 9, 1998, and, thereafter, will occur each
       January 1 and July 1, or the first business day thereafter (the "Offering
       Commencement Dates"). Each Offering Commencement Date will begin a six
       (6) month period (a "Plan Period") during which payroll deductions will
       be made and held for the purchase of Common Stock at the end of the Plan
       Period (except that the first Plan Period will end on April 30, 1998).
       The Board or the Committee may, at its discretion, choose a different
       Plan Period of twelve (12) months or less for subsequent Offerings. No
       more than 50,000 shares of Common Stock shall be eligible for purchase in
       any Plan Period.

    4.  PARTICIPATION. An employee eligible on the Offering Commencement Date of
       any Offering may participate in such Offering by completing and
       forwarding a payroll deduction authorization form to the employee's
       appropriate payroll office at least 14 days prior to the applicable
       Offering Commencement Date (five days in the case of the first Plan
       Period). The form will authorize a regular payroll deduction from the
       Compensation received by the employee during the Plan Period. Unless an
       employee files a new form or withdraws from the Plan, his

                                     D-3-1
<PAGE>
       deductions and purchases will continue at the same rate for future
       Offerings under the Plan as long as the Plan remains in effect. The term
       "Compensation" means the amount of money reportable on the employee's
       Federal Income Tax Withholding Statement, excluding overtime, shift
       premium, incentive or bonus awards, allowances and reimbursements for
       expenses such as relocation allowances for travel expenses, income or
       gains on the exercise of Company stock options or stock appreciation
       rights, and similar items, whether or not shown on the employee's Federal
       Income Tax Withholding Statement, but including, in the case of
       salespersons, sales commissions to the extent determined by the Board or
       the Committee.

    5.  DEDUCTIONS. The Company will maintain payroll deduction accounts for all
       participating employees. With respect to any Offering made under this
       Plan, an employee may authorize a payroll deduction in any dollar amount
       up to a maximum of 10% of the Compensation he or she receives during the
       Plan Period or such shorter period during which deductions from payroll
       are made.

    No employee may be granted an Option (as defined in Section 9) which permits
his rights to purchase Common Stock under this Plan and any other employee stock
purchase plan (as defined in Section 423(b) of the Code) of the Company and its
subsidiaries, to accrue at a rate which exceeds $25,000 of the fair market value
of such Common Stock (determined at the Offering Commencement Date of the Plan
Period) for each calendar year in which the Option is outstanding at any time.

    6.  DEDUCTION CHANGES. An employee may decrease or discontinue his payroll
       deduction once during any Plan Period, by filing a new payroll deduction
       authorization form. However, an employee may not increase his payroll
       deduction during a Plan Period. If an employee elects to discontinue his
       payroll deductions during a Plan Period, but does not elect to withdraw
       his funds pursuant to Section 8 hereof, funds deducted prior to his
       election to discontinue will be applied to the purchase of Common Stock
       on the Exercise Date (as defined below).

    7.  INTEREST. Interest will not be paid on any employee accounts, except to
       the extent that the Board or the Committee, in its sole discretion,
       elects to credit employee accounts with interest at such per annum rate
       as it may from time to time determine.

    8.  WITHDRAWAL OF FUNDS. An employee may at any time prior to the close of
       business on the last business day in a Plan Period and for any reason
       permanently draw out the balance accumulated in the employee's account
       and thereby withdraw from participation in an Offering. Partial
       withdrawals are not permitted. The employee may not begin participation
       again during the remainder of the Plan Period. The employee may
       participate in any subsequent Offering in accordance with terms and
       conditions established by the Board or the Committee.

    9.  PURCHASE OF SHARES. On the Offering Commencement Date of each Plan
       Period, the Company will grant to each eligible employee who is then a
       participant in the Plan an option ("Option") to purchase on the last
       business day of such Plan Period (the "Exercise Date"), at the Option
       Price hereinafter provided for, the largest number of whole shares of
       Common Stock of the Company as does not exceed the number of shares
       determined by dividing $12,500 by the closing price (as defined below) on
       the Offering Commencement Date of such Plan Period.

    The purchase price for each share purchased will be 85% of the closing price
of the Common Stock on (i) the first business day of such Plan Period or
(ii) the Exercise Date, whichever closing price shall be less. Such closing
price shall be (a) the closing price on any national securities exchange on
which the Common Stock is listed, (b) the closing price of the Common Stock on
the Nasdaq National Market or (c) the average of the closing bid and asked
prices in the over-the-counter-market, whichever is applicable, as published in
The Wall Street Journal. If no sales of Common Stock were made on such

                                     D-3-2
<PAGE>
a day, the price of the Common Stock for purposes of clauses (a) and (b) above
shall be the reported price for the next preceding day on which sales were made.

    Each employee who continues to be a participant in the Plan on the Exercise
Date shall be deemed to have exercised his Option at the Option Price on such
date and shall be deemed to have purchased from the Company the number of full
shares of Common Stock reserved for the purpose of the Plan that his accumulated
payroll deductions on such date will pay for, but not in excess of the maximum
number determined in the manner set forth above.

    Any balance remaining in an employee's payroll deduction account at the end
of a Plan Period will be automatically refunded to the employee, except that any
balance which is less than the purchase price of one share of Common Stock will
be carried forward into the employee's payroll deduction account for the
following Offering, unless the employee elects not to participate in the
following Offering under the Plan, in which case the balance in the employee's
account shall be refunded.

    10. ISSUANCE OF CERTIFICATES. Certificates representing shares of Common
       Stock purchased under the Plan may be issued only in the name of the
       employee, in the name of the employee and another person of legal age as
       joint tenants with rights of survivorship, or (in the Company's sole
       discretion) in the name of a brokerage firm, bank or other nominee holder
       designated by the employee. The Company may, in its sole discretion and
       in compliance with applicable laws, authorize the use of book entry
       registration of shares in lieu of issuing stock certificates.

    11. RIGHTS ON RETIREMENT, DEATH OR TERMINATION OF EMPLOYMENT. In the event
       of a participating employee's termination of employment prior to the last
       business day of a Plan Period, no payroll deduction shall be taken from
       any pay due and owing to an employee and the balance in the employee's
       account shall be paid to the employee or, in the event of the employee's
       death, (a) to a beneficiary previously designated in a revocable notice
       signed by the employee (with any spousal consent required under state
       law) or (b) in the absence of such a designated beneficiary, to the
       executor or administrator of the employee's estate or (c) if no such
       executor or administrator has been appointed to the knowledge of the
       Company, to such other person(s) as the Company may, in its discretion,
       designate. If, prior to the last business day of the Plan Period, the
       Designated Subsidiary by which an employee is employed shall cease to be
       a subsidiary of the Company, or if the employee is transferred to a
       subsidiary of the Company that is not a Designated Subsidiary, the
       employee shall be deemed to have terminated employment for the purposes
       of this Plan.

    12. OPTIONEES NOT STOCKHOLDERS. Neither the granting of an Option to an
       employee nor the deductions from his pay shall constitute such employee a
       stockholder of the shares of Common Stock covered by an Option under this
       Plan until such shares have been purchased by and issued to him.

    13. RIGHTS NOT TRANSFERABLE. Rights under this Plan are not transferable by
       a participating employee other than by will or the laws of descent and
       distribution, and are exercisable during the employee's lifetime only by
       the employee.

    14. APPLICATION OF FUNDS. All funds received or held by the Company under
       this Plan may be combined with other corporate funds and may be used for
       any corporate purpose.

    15. ADJUSTMENT IN CASE OF CHANGES AFFECTING COMMON STOCK. In the event of a
       subdivision of outstanding shares of Common Stock, or the payment of a
       dividend in Common Stock, the number of shares approved for this Plan,
       and the share limitation set forth in Section 9, shall be increased
       proportionately, and such other adjustment shall be made as may be deemed
       equitable by the Board or the Committee. In the event of any other change
       affecting the Common Stock, such adjustment shall be made as may be
       deemed equitable by the Board or the Committee to give proper effect to
       such event.

                                     D-3-3
<PAGE>
    16. MERGER. If the Company shall at any time merge or consolidate with
       another corporation and the holders of the capital stock of the Company
       immediately prior to such merger or consolidation continue to hold at
       least 80% by voting power of the capital stock of the surviving
       corporation ("Continuity of Control"), the holder of each Option then
       outstanding will thereafter be entitled to receive at the next Exercise
       Date upon the exercise of such Option for each share as to which such
       Option shall be exercised the securities or property which a holder of
       one share of the Common Stock was entitled to upon and at the time of
       such merger or consolidation, and the Committee shall take such steps in
       connection with such merger or consolidation as the Board or the
       Committee shall deem necessary to assure that the provisions of Section
       15 shall thereafter be applicable, as nearly as reasonably may be, in
       relation to the said securities or property as to which such holder of
       such Option might thereafter be entitled to receive thereunder.

    In the event of a merger or consolidation of the Company with or into
another corporation which does not involve Continuity of Control, or of a sale
of all or substantially all of the assets of the Company while unexercised
Options remain outstanding under the Plan, all outstanding Options shall be
cancelled by the Board or the Committee as of the effective date of any such
transaction, provided that notice of such cancellation shall be given to each
holder of an Option, and each holder of an Option shall have the right to
exercise such Option in full based on payroll deductions then credited to his
account as of a date determined by the Board or the Committee, which date shall
not be less than ten (10) days preceding the effective date of such transaction.

    17. AMENDMENT OF THE PLAN. The Board may at any time, and from time to time,
       amend this Plan in any respect, except that (a) if the approval of any
       such amendment by the shareholders of the Company is required by Section
       423 of the Code, such amendment shall not be effected without such
       approval, and (b) in no event may any amendment be made which would cause
       the Plan to fail to comply with Section 423 of the Code.

    18. INSUFFICIENT SHARES. In the event that the total number of shares of
       Common Stock specified in elections to be purchased under any Offering
       plus the number of shares purchased under previous Offerings under this
       Plan exceeds the maximum number of shares issuable under this Plan, the
       Board or the Committee will allot the shares then available on a pro rata
       basis.

    19. TERMINATION OF THE PLAN. This Plan may be terminated at any time by the
       Board. Upon termination of this Plan all amounts in the accounts of
       participating employees shall be promptly refunded.

    20. GOVERNMENTAL REGULATIONS. The Company's obligation to sell and deliver
       Common Stock under this Plan is subject to listing on a national stock
       exchange or quotation on the Nasdaq National Market and the approval of
       all governmental authorities required in connection with the
       authorization, issuance or sale of such stock.

    The Plan shall be governed by Delaware law except to the extent that such
law is preempted by federal law.

    21. ISSUANCE OF SHARES. Shares may be issued upon exercise of an Option from
       authorized but unissued Common Stock, from shares held in the treasury of
       the Company, or from any other proper source.

    22. NOTIFICATION UPON SALE OF SHARES. Each employee agrees, by entering the
       Plan, to promptly give the Company notice of any disposition of shares
       purchased under the Plan where such disposition occurs within two years
       after the date of grant of the Option pursuant to which such shares were
       purchased.

                                     D-3-4

    23. EFFECTIVE DATE AND APPROVAL OF STOCKHOLDERS. The Plan shall take effect
       on July 31, 1997 subject to approval by the stockholders of the Company
       as required by Section 423 of the Code, which approval must occur within
       twelve months of the adoption of the Plan by the Board.
