          (2)     to the extent Consolidated Net Income has been reduced
                  thereby,

                  -    all income taxes of such Person and its Restricted
                       Subsidiaries paid or accrued in accordance with GAAP for
                       such period (other than income taxes attributable to
                       extraordinary gains or losses or income taxes
                       attributable to Asset Sales and other sales or
                       dispositions outside the ordinary course of business to
                       the extent that gains or losses from such transactions
                       have been excluded from the computation of Consolidated
                       Net Income),

                  -    Consolidated Interest Expense, and

                  -    Consolidated Non-cash Charges less any non-cash items
                       increasing Consolidated Net Income for such period
                       (except to the extent such non-cash item increasing
                       Consolidated Net Income relates to a cash benefit for any
                       future period),

all as determined on a consolidated basis for such Person and its Restricted
Subsidiaries in accordance with GAAP.

          "CONSOLIDATED FIXED CHARGE COVERAGE RATIO" means, with respect to any
Person, the ratio of (x) Consolidated EBITDA of such Person during the four full
fiscal quarters for which financial statements are available (the "FOUR QUARTER
PERIOD") ending on or prior to the Transaction Date to (y) Consolidated Fixed
Charges of such Person for the Four Quarter Period.

          For purposes of this definition, "Consolidated EBITDA" and
"Consolidated Fixed Charges" shall be calculated after giving effect on a pro
forma basis in accordance with Regulation S-X under the Exchange Act to the
incurrence, repayment or redemption of any Indebtedness of such Person or any of
its Restricted Subsidiaries giving rise to the need to make such calculation and
any incurrence, repayment or redemption of other Indebtedness, other than the
incurrence, repayment or redemption of Indebtedness in the ordinary course of
business for working capital purposes pursuant to working capital facilities,
occurring during the Four Quarter Period or at any time subsequent to the last
day of the Four Quarter Period and prior to the Transaction Date, as if such
incurrence, repayment or redemption, as the case may be, occurred on the first
day of the Four Quarter Period.

          In addition, Investments (including any Designation of Unrestricted
Subsidiaries), Revocations, acquisitions, dispositions, mergers and
consolidations that have been made by Casella or any of its Restricted
Subsidiaries during the Four Quarter Period or subsequent to the Four Quarter
Period and on or prior to the Transaction Date shall be given effect on a

<Page>

                                       -8-

pro forma basis in accordance with Regulation S-X under the Exchange Act, to the
extent applicable, assuming that all such Investments, Revocations,
acquisitions, dispositions, mergers and consolidations (and the reduction or
increase of any associated Consolidated Fixed Charges and the change in
Consolidated EBITDA, resulting therefrom) had occurred on the first day of the
Four Quarter Period. If, since the beginning of such period, any Person (that
subsequently became a Restricted Subsidiary or was merged with or into Casella
or any Restricted Subsidiary since the beginning of such period) shall have made
any Investment, Revocation, acquisition, disposition, merger or consolidation
that would have required adjustment pursuant to this definition, then the
Consolidated Fixed Charge Coverage Ratio shall be calculated giving pro forma
effect thereto for such period as if such Investment, Revocation, acquisition,
disposition, merger or consolidation had occurred at the beginning of the
applicable Four Quarter Period.

          If such Person or any of its Restricted Subsidiaries directly or
indirectly Guarantees Indebtedness of a Person other than Casella or a
Restricted Subsidiary, the preceding paragraph will give effect to the
incurrence of such Guaranteed Indebtedness as if such Person or any Restricted
Subsidiary of such Person had directly incurred or otherwise assumed such
Guaranteed Indebtedness.

          Furthermore, in calculating "Consolidated Fixed Charges" for purposes
of determining the denominator (but not the numerator) of this "Consolidated
Fixed Charge Coverage Ratio,"

          (1)     interest on outstanding Indebtedness determined on a
                  fluctuating basis as of the Transaction Date and which will
                  continue to be so determined thereafter shall be deemed to
                  have accrued at a fixed rate per annum equal to the weighted
                  average rate of interest during the Four Quarter Period;

          (2)     if interest on any Indebtedness actually incurred on the
                  Transaction Date may optionally be determined at an interest
                  rate based upon a factor of a prime or similar rate, a
                  eurocurrency interbank offered rate, or other rates, then the
                  interest rate in effect on the Transaction Date will be deemed
                  to have been in effect during the Four Quarter Period; and

          (3)     notwithstanding clause (1) above, interest on Indebtedness
                  determined on a fluctuating basis, to the extent such interest
                  is covered by agreements relating to Hedging Obligations,
                  shall be deemed to accrue at the weighted average rate per
                  annum during the Four Quarter Period resulting after giving
                  effect to the operation of such agreements.

period, the sum, without duplication, of

          (2)     the amount of all dividend payments on any series of Preferred
                  Stock of such Person and its Restricted Subsidiaries (other
                  than dividends paid in Qualified Capital Stock and other than
                  dividends paid to such Person or to a Restricted Subsidiary of
                  such Person) paid, accrued or scheduled to be paid or accrued
                  during such period (PROVIDED that dividends paid by the
                  increase in liquidation preference, or the issuance, of

                                    THE NOTES

SECTION 2.01.  FORM AND DATING.

          The Notes and the Trustee's certificate of authentication shall be
substantially in the form of EXHIBIT A hereto. The Notes may have notations,
legends or endorsements required by law, stock exchange rule or usage. Casella
shall approve the form of the Notes and any notation, legend or endorsement on
them. Each Note shall be dated the date of its issuance and show the date of its
authentication. Each Note shall have an executed Subsidiary Guarantee from each
of the Guarantors endorsed thereon substantially in the form of EXHIBIT E.

          The terms and provisions contained in the Notes and the Subsidiary
Guarantees shall constitute, and are hereby expressly made, a part of this
Indenture and, to the extent applicable, Casella, the Guarantors and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.

          Notes offered and sold in reliance on Rule 144 and Notes offered and
sold in reliance on Regulation S shall be issued initially in the form of one or
more Global Notes, substantially in the form set forth in EXHIBIT A, deposited
with the Trustee, as custodian for the Depository, duly executed by Casella (and

          Notes issued in exchange for interests in a Global Note pursuant to
Section 2.16 may be issued in the form of permanent certificated Notes in
registered form in substantially the form set forth in EXHIBIT A (the "PHYSICAL
NOTES").

SECTION 2.02.  EXECUTION AND AUTHENTICATION.

          One Officer of Casella (who shall have been duly authorized by all
requisite corporate actions) shall sign the Notes for Casella by manual or
facsimile signature.

          If an Officer whose signature is on a Note or Subsidiary Guarantee, as
the case may be, was an Officer at the time of such execution but no longer
holds that office at the time the Trustee authenticates the Note, the Note shall
nevertheless be valid.

          A Note shall not be valid until an authorized signatory of the Trustee
manually signs the certificate of authentication on the Note. The signature
shall be conclusive evidence that the Note has been authenticated under this
Indenture.

          The Trustee shall authenticate Notes for original issue on the Issue
Date in the aggregate principal amount of $150,000,000 upon a written order of
Casella in the form of an Officers' Certificate. In addition, the Trustee shall
authenticate Notes thereafter in unlimited amount (so long as not otherwise
prohibited by the terms of this Indenture, including without limitation, Section
4.10) for original issue upon a written order of Casella in the form of an
Officers' Certificate. Each such Officers' Certificate shall specify the amount
of Notes to be authenticated and the date on which the Notes are to be
authenticated.

          The Trustee may appoint an authenticating agent reasonably acceptable
to Casella to authenticate Notes. Unless otherwise provided in the appointment,
an authenticating agent may authenticate Notes whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent has the same rights as an
Agent to deal with Casella and Affiliates of Casella.

          The Notes shall be issuable only in registered form without coupons in
denominations of $1,000 and integral multiples thereof.

SECTION 2.03.  REGISTRAR AND PAYING AGENT.

          Casella shall maintain an office or agency in the Borough of
Manhattan, The City of New York, where (a) Notes may be presented or surrendered
for registration of transfer or for exchange ("REGISTRAR"), (b) Notes may be
presented or surrendered for payment ("PAYING AGENT") and (c) notices and
demands to or upon Casella in respect of the Notes and this Indenture may be
served. Casella may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes

<Page>

                                      -35-

and may from time to time rescind such designations; PROVIDED, HOWEVER, that no
such designation or rescission shall in any manner relieve Casella of its
obligation to maintain an office or agency in the Borough of Manhattan, The City
of New York, for such purposes. Casella may act as its own Registrar or Paying
Agent, except that for the purposes of Articles Three and Eight and Sections
4.09 and 4.13, neither Casella nor any Affiliate of Casella shall act as Paying
Agent. The Registrar shall keep a register of the Notes and of their transfer
and exchange. Casella, upon notice to the Trustee, may have one or more
co-Registrars and one or more additional paying agents reasonably acceptable to
the Trustee. The term "Paying Agent" includes any additional paying agent.
Casella initially appoints the Trustee as Registrar and Paying Agent until such
time as the Trustee has resigned or a successor has been appointed.

          Casella shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture, which agreement shall implement the
provisions of this Indenture that relate to such Agent. Casella shall notify the
Trustee, in advance, of the name and address of any such Agent. If Casella fails
to maintain a Registrar or Paying Agent, the Trustee shall act as such.

SECTION 2.04.  PAYING AGENT TO HOLD ASSETS IN TRUST.

          Casella shall require each Paying Agent other than the Trustee to
agree in writing that, subject to Article Ten and Section 11.02, each Paying
Agent shall hold in trust for the benefit of Holders or the Trustee all assets
held by the Paying Agent for the payment of principal of, or interest on, the
Notes (whether such assets have been distributed to it by Casella or any other
obligor on the Notes), and shall notify the Trustee of any Default by Casella
(or any other obligor on the Notes) in making any such payment. Casella at any
time may require a Paying Agent to distribute all assets held by it to the
Trustee and account for any assets disbursed and the Trustee may at any time
during the continuance of any payment Default, upon written request to a Paying
Agent, require such Paying Agent to distribute all assets held by it to the
Trustee and to account for any assets distributed. Upon distribution to the
Trustee of all assets that shall have been delivered by Casella to the Paying
Agent, the Paying Agent shall have no further liability for such assets.

SECTION 2.05.  HOLDER LISTS.

          The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders. If the Trustee is not the Registrar, Casella shall furnish to the
Trustee at least two (2) Business Days prior to each Interest Payment Date and
at such other times as the Trustee may request in writing a list in such form
and as of such date as the Trustee may reasonably require of the names and
addresses of Holders, which list may be conclusively relied upon by the Trustee.

SECTION 2.06.  TRANSFER AND EXCHANGE.

          Subject to Sections 2.15 and 2.16, when Notes are presented to the
Registrar or a co-Registrar with a request to register the transfer of such
Notes or to exchange such Notes for an equal principal amount of Notes of other
authorized denominations, the Registrar or co-Registrar shall register the
transfer or make the exchange as requested if its requirements for such
transaction are met; PROVIDED, HOWEVER, that the Notes surrendered for transfer
or exchange shall be duly endorsed or accompanied by a written instrument of
transfer in form satisfactory to Casella and the Registrar or co-Registrar, duly
executed by the Holder thereof or his or her attorney duly authorized in
writing. To permit registrations of transfers and exchanges, Casella shall
execute and the Trustee shall authenticate Notes at the Registrar's or
co-Registrar's request. No service charge shall be made for any registration of
transfer or exchange, but Casella may require payment of a sum sufficient to
cover any transfer tax or similar governmental charge payable in connection
therewith.

          The Registrar or co-Registrar shall not be required to register the
transfer of or exchange of any Note (i) during a period beginning at the opening
of business 15 days before the mailing of a notice of redemption of Notes and
ending at the close of business on the day of such mailing, (ii) selected for
redemption in whole or in part pursuant to Article Three, except the unredeemed
portion of any Note being redeemed in part, and (iii) during a Change of Control
Offer, an Alternate Offer or an Asset Sale Offer if such Note is tendered
pursuant to such Change of Control Offer, Alternate Offer or Asset Sale Offer
and not withdrawn.

          Any Holder of a beneficial interest in a Global Note shall, by
acceptance of such beneficial interest, agree that transfers of beneficial
interests in such Global Notes may be effected only through a book-entry system
maintained by the Holder of such Global Note (or its agent), and that ownership
of a beneficial interest in the Note shall be required to be reflected in a
book-entry system.

SECTION 2.07.  REPLACEMENT NOTES.

          If a mutilated Note is surrendered to the Trustee or if the Holder of
a Note claims that the Note has been lost, destroyed or wrongfully taken,
Casella shall issue and the Trustee shall authenticate a replacement Note if the
Trustee's requirements are met. Such Holder must provide an indemnity bond or
other indemnity, sufficient in the judgment of both Casella and the Trustee, to
protect Casella, the Trustee or any Agent from any loss which any of them may
suffer if a Note is replaced. Casella may charge such Holder for its reasonable
out-of-pocket expenses in replacing a Note pursuant to this Section 2.07,
including reasonable fees and expenses of counsel and of the Trustee.

<Page>

                                      -37-

          Every replacement Note is an additional obligation of Casella and
every replacement Subsidiary Guarantee shall constitute an additional obligation
of the Guarantor thereof.

SECTION 2.08.  OUTSTANDING NOTES.

          Notes outstanding at any time are all the Notes that have been
authenticated by the Trustee except those cancelled by it, those delivered to it
for cancellation and those described in this Section as not outstanding. A Note
does not cease to be outstanding because Casella, the Guarantors or any of their
respective Affiliates holds the Note (subject to the provisions of
Section 2.09).

          If a Note is replaced pursuant to Section 2.07 (other than a mutilated
Note surrendered for replacement), it ceases to be outstanding unless a
Responsible Officer of the Trustee receives proof satisfactory to it that the
replaced Note is held by a BONA FIDE purchaser. A mutilated Note ceases to be
outstanding upon surrender of such Note and replacement thereof pursuant to
Section 2.07.

          If the principal amount of any Note is considered paid under
Section 4.01, it ceases to be outstanding and interest ceases to accrue. If on a
Redemption Date or the Maturity Date the Trustee or Paying Agent (other than
Casella or an Affiliate thereof) holds U.S. Legal Tender or U.S. Government
Obligations sufficient to pay all of the principal and interest due on the Notes
payable on that date, then on and after that date such Notes cease to be
outstanding and interest on them ceases to accrue.

SECTION 2.09.  TREASURY NOTES.

          In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by Casella
or any of its Affiliates shall be disregarded, except that, for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Notes that a Responsible Officer of the
Trustee actually knows are so owned shall be disregarded.

SECTION 2.10.  TEMPORARY NOTES.

          Until definitive Notes are ready for delivery, Casella may prepare and
the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that
Casella considers appropriate for temporary Notes. Without unreasonable delay,
Casella shall prepare and the Trustee shall authenticate definitive Notes in
exchange for temporary Notes. Until such exchange, temporary Notes shall be
entitled to the same rights, benefits and privileges as definitive Notes.
Notwithstanding
<Page>

                                      -38-

the foregoing, so long as the Notes are represented by a Global Note, such
Global Note may be in typewritten form.

SECTION 2.11.  CANCELLATION.

          Casella at any time may deliver Notes to the Trustee for cancellation.
The Registrar and the Paying Agent shall forward to the Trustee any Notes
surrendered to them for transfer, exchange or payment. The Trustee, or at the
direction of the Trustee, the Registrar or the Paying Agent (other than Casella
or a Subsidiary), and no one else, shall cancel and, at the written direction of
Casella, shall dispose of all Notes surrendered for transfer, exchange, payment
or cancellation in accordance with its customary procedures. Subject to Section
2.07, Casella may not issue new Notes to replace Notes that it has paid or
delivered to the Trustee for cancellation. If Casella or any Guarantor shall
acquire any of the Notes, such acquisition shall not operate as a redemption or
satisfaction of the Indebtedness represented by such Notes unless and until the
same are surrendered to the Trustee for cancellation pursuant to this
Section 2.11.

SECTION 2.12.  DEFAULTED INTEREST.

          If Casella defaults in a payment of interest on the Notes, it shall,
unless the Trustee fixes another record date pursuant to Section 6.10, pay the
defaulted interest, plus (to the extent lawful) any interest payable on the
defaulted interest, in any lawful manner. Casella may pay the defaulted interest
to the persons who are Holders on a subsequent special record date, which date
shall be the fifteenth day next preceding the date fixed by Casella for the
payment of defaulted interest or the next succeeding Business Day if such date
is not a Business Day. At least 15 days before any such subsequent special
record date, Casella shall mail to each Holder, with a copy to the Trustee, a
notice that states the subsequent special record date, the payment date and the
amount of defaulted interest, and interest payable on such defaulted interest,
if any, to be paid.

SECTION 2.13.  CUSIP NUMBER.

          Casella in issuing the Notes may use a "CUSIP" number, and if so, the
Trustee shall use the CUSIP number in notices of redemption or exchange as a
convenience to Holders; PROVIDED, HOWEVER, that any such notice may state that
no representation is made as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Notes, and that reliance may be placed only on
the other identification numbers printed on the Notes. Casella will promptly
notify the Trustee of any change in the CUSIP numbers.

                                      -39-

SECTION 2.14.  DEPOSIT OF MONEYS.

          Prior to 10:00 a.m. New York City time on each Interest Payment Date,
Maturity Date, Redemption Date, Change of Control Payment Date and Asset Sale
Offer Payment Date, Casella shall have deposited with the Paying Agent in
immediately available funds money sufficient to make cash payments, if any, due
on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control
Payment Date and Asset Sale Offer Payment Date, as the case may be, in a timely
manner which permits the Paying Agent to remit payment to the Holders on such
Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment
Date and Asset Sale Offer Payment Date, as the case may be.

their behalf by the Depository, or the Trustee as its custodian, or under the
Global Note, and the Depository may be treated by Casella, the Trustee and any
agent of Casella or the Trustee as the absolute owner of the Global Note for all
purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
Casella, the Trustee or any agent of Casella or the Trustee from giving effect
to any written certification, proxy or other authorization furnished by the
Depository or impair, as between the Depository and Participants, the operation
of customary practices governing the exercise of the rights of a Holder of any
Note.

          (b)     Transfers of Global Notes shall be limited to transfers in
whole, but not in part, to the Depository, its successors or their respective
nominees. Interests of beneficial owners in the Global Notes may be transferred
or exchanged for Physical Notes in accordance with the rules and procedures of
the Depository and the provisions of Section 2.16. In addition, Physical Notes
shall be transferred to all beneficial owners in exchange for their beneficial
interests in Global Notes if (i) the Depository notifies Casella that it is
unwilling or unable to continue as Depository for any Global Note and a
successor Depository is not appointed by Casella, with a copy to the Trustee,
within 90 days of such notice or (ii) a Default has occurred and is continuing
and the Registrar has received a written request from the Depository to issue
Physical Notes.

          (c)     In connection with any transfer or exchange of a portion of
the beneficial interest in a Global Note to beneficial owners pursuant to
paragraph (b) of this Section 2.15, the Registrar shall (if one or more Physical
Notes are to be issued) reflect on its books

<Page>

                                      -40-

and records the date and a decrease in the principal amount of such Global Note
in an amount equal to the principal amount of the beneficial interest in the
Global Note to be transferred, and Casella shall execute, and the Trustee shall
authenticate and deliver, one or more Physical Notes of authorized denominations
in an aggregate principal amount equal to the principal amount of the beneficial
interest in the Global Note so transferred.

          (d)     In connection with the transfer of a Global Note as an
entirety to beneficial owners pursuant to paragraph (b) of this Section 2.15,
such Global Note shall be deemed to be surrendered to the Trustee for
cancellation, and (i) Casella shall execute, (ii) the Guarantors shall execute
notations of Subsidiary Guarantees on and (iii) the Trustee shall upon written
instructions from Casella authenticate and deliver, to each beneficial owner
identified by the Depository in exchange for its beneficial interest in such
Global Note, an equal aggregate principal amount of Physical Notes of authorized
denominations.

          (e)     Any Physical Note constituting a Restricted Security delivered
in exchange for an interest in a Global Note pursuant to paragraph (b) or (c) of
this Section 2.15 shall, except as otherwise provided by Section 2.16, bear the
Private Placement Legend.

          (f)     The Holder of any Global Note may grant proxies and otherwise
authorize any Person, including Participants and Persons that may hold interests
through Participants, to take any action which a Holder is entitled to take

<Page>

                                      -42-

     and that it is aware that the transferor is relying upon its foregoing

<Page>

                                      -44-

          -    if the Notes are listed on a national securities exchange, in
               compliance with the requirements of the principal national
               securities exchange on which the Notes are listed; or

          -    if the Notes are not so listed, on a PRO RATA basis, by lot or by
               such method as the Trustee shall deem fair and appropriate;

PROVIDED that, in the case of such redemption pursuant to Section 6 of the Notes
or with Net Proceeds from an Asset Sale pursuant to the provisions of clause (3)
of the second paragraph of Section 4.13, the Trustee will select the Notes on a
PRO RATA basis or on as nearly a PRO RATA basis as practicable (subject to the
procedures of the Depository).

          No Notes of $1,000 or less shall be redeemed in part.

SECTION 3.03.  NOTICE OF REDEMPTION.

          At least 30 days but not more than 60 days before a Redemption Date,
Casella shall mail a notice of redemption by first class mail, postage prepaid,
to each Holder whose Notes are to be redeemed at its registered address. At
Casella's request, the Trustee shall forward the notice of redemption in
Casella's name and at Casella's expense. Each notice for redemption shall
identify the Notes (including the CUSIP number) to be redeemed and shall state:

          (1)     the Redemption Date;

          (2)     the Redemption Price and the amount of accrued interest, if

          (5)     that, unless Casella defaults in making the redemption
     payment, interest on Notes called for redemption ceases to accrue on and
     after the Redemption Date, and the only remaining right of the Holders of
     such Notes is to receive payment of the Redemption Price upon surrender to
     the Paying Agent of the Notes redeemed;

          (6)     if any Note is being redeemed in part, the portion of the
     principal amount of such Note to be redeemed and that, after the Redemption
     Date, and upon surrender of such Note, a new Note or Notes in aggregate
     principal amount equal to the unredeemed portion thereof will be issued;

<Page>

                                      -45-

     redeemed.

          The notice, if mailed in a manner herein provided, shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Note designated for redemption in whole or in
part shall not affect the validity of the proceedings for the redemption of any
other Note. Notices of redemption may not be conditional.

SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION.

          Once notice of redemption is mailed in accordance with Section 3.03,
Notes called for redemption become due and payable on the Redemption Date and at
the Redemption Price plus accrued interest, if any. Upon surrender to the
Trustee or Paying Agent, such Notes called for redemption shall be paid at the
Redemption Price (which shall include accrued interest thereon to the Redemption
Date), but installments of interest, the maturity of which is on or prior to the
Redemption Date, shall be payable to Holders of record at the close of business
on the relevant Record Dates. On and after the Redemption Date interest shall
cease to accrue on Notes or portions thereof called for redemption.

SECTION 3.05.  DEPOSIT OF REDEMPTION PRICE.

          On or before 10:00 a.m. New York time on the Redemption Date, Casella
shall deposit with the Paying Agent U.S. Legal Tender sufficient to pay the
Redemption Price plus accrued interest, if any, of all Notes to be redeemed on
that date.

          If Casella complies with the preceding paragraph, then, unless Casella
defaults in the payment of such Redemption Price plus accrued interest, if any,
interest on the Notes to be redeemed will cease to accrue on and after the
applicable Redemption Date, whether or not such Notes are presented for payment.

SECTION 3.06.  NOTES REDEEMED IN PART.

          If any Note is to be redeemed in part only, the notice of redemption

thereof to be redeemed. A new Note or Notes in principal amount equal to the
unredeemed portion of the original Note or

<Page>

                                      -46-

the Notes.

SECTION 4.02.  MAINTENANCE OF OFFICE OR AGENCY.

          Casella shall maintain in the Borough of Manhattan, The City of New
York, the office or agency required under Section 2.03. Casella shall give
prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time Casella shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the address of the Trustee set forth in Section 12.02.

          Casella may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations. Casella will give
prompt written notice to the Trustee of any such designation or rescission and
of any change in the location of any such other office or agency.

          Casella hereby initially designates U.S. Bank National Association,

organizational documents of each such Restricted Subsidiary and the rights
(charter and statutory) and material franchises of Casella and each of its
Restricted Subsidiaries; PROVIDED, HOWEVER, that Casella shall not be required
to preserve any such right, franchise or corporate existence with respect to
each such Restricted Subsidiary if the loss thereof would not, individually or
in the aggregate, have a material adverse effect on the business, financial
condition or results of operations of Casella and its Restricted Subsidiaries
taken as a whole.

SECTION 4.04.  PAYMENT OF TAXES AND OTHER CLAIMS.

          Each of Casella and the Guarantors shall, and shall cause each of the
respective Subsidiaries to, pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (a) all material taxes, assessments and
governmental charges levied or imposed upon it or any of its respective
Subsidiaries or upon the income, profits or property of it or any of its
respective Subsidiaries and (b) all lawful claims for labor, materials and
supplies which, in each case, if unpaid, might by law become a material
liability or Lien upon the property of it or any of its Restricted Subsidiaries;
PROVIDED, HOWEVER, that Casella and the Guarantors shall not be required to pay
or discharge or cause to be paid or discharged any such tax, assessment, charge
or claim whose amount the applicability or validity is being contested in good
faith by appropriate proceedings and for which appropriate provision has been
made.

SECTION 4.05.  MAINTENANCE OF PROPERTIES AND INSURANCE.

          (a)     Casella shall cause all material properties owned by or leased
by it or any of its Restricted Subsidiaries used or useful to the conduct of its
business or the business of any of its Restricted Subsidiaries to be maintained
and kept in normal condition, repair and working order and supplied with all
necessary equipment and shall cause to be made all repairs, renewals,
replacements, and betterments thereof, all as in its judgment may be necessary,
so that the business carried on in connection therewith may be properly and
advantageously conducted at all times; PROVIDED, HOWEVER, that nothing in this
Section 4.05 shall prevent Casella or any of its Restricted Subsidiaries from
discontinuing the use, operation or maintenance of any of such properties, or
disposing of any of them, if such discontinuance or disposal is, in the judgment
of the Board of Directors of Casella or any such Restricted Subsidiary desirable
in the conduct of the business of Casella or any such Restricted Subsidiary, and
if such discontinuance or disposal would not, individually or in the aggregate,
have a material

<Page>

                                      -48-

adverse effect on the ability of Casella or the Guarantors to perform each of
their respective obligations hereunder; PROVIDED, FURTHER, that nothing in this
Section 4.05 shall prevent Casella or any of its Restricted Subsidiaries from
discontinuing or disposing of any properties to the extent otherwise permitted
by this Indenture.

          (b)     Casella shall maintain, and shall cause its Restricted
Subsidiaries to maintain, insurance with responsible carriers against such risks
and in such amounts, and with such deductibles, retentions, self-insured amounts
and co-insurance provisions, as are customarily carried by similar businesses of
similar size, including property and casualty loss, workers' compensation and
interruption of business insurance.

SECTION 4.06.  COMPLIANCE CERTIFICATE; NOTICE OF DEFAULT.

          (a)     Casella shall deliver to the Trustee, within 120 days after
the close of each fiscal year (which on the date hereof is April 30), an
Officers' Certificate stating that a review of the activities of Casella and its
Subsidiaries has been made under the supervision of the signing Officers with a
view to determining whether Casella and each Guarantor has kept, observed,
performed and fulfilled its obligations under this Indenture and further
stating, as to each such Officer signing such certificate, that to the best of
such Officer's knowledge, Casella and each Guarantor during such preceding
fiscal year has kept, observed, performed and fulfilled each and every such
covenant and no Default occurred during such year and at the date of such
certificate there is no Default that has occurred and is continuing or, if such
signers do know of such Default, the certificate shall describe its status with
particularity. The Officers' Certificate shall also notify the Trustee should
Casella elect to change the manner in which it fixes its fiscal year end.

          (b)     Casella shall deliver to the Trustee as soon as possible and
in any event within five days after Casella becomes aware of the occurrence of
any Default an Officers' Certificate specifying the Default and describing its
status with particularity and the action proposed to be taken thereto.

SECTION 4.07.  COMPLIANCE WITH LAWS.

          Casella shall comply, and shall cause each of its Subsidiaries to
comply, with all applicable statutes, rules, regulations, orders and
restrictions of the United States, all states and municipalities thereof, and of
any governmental department, commission, board, regulatory authority, bureau,
agency and instrumentality of the foregoing, in respect of the conduct of their
respective businesses and the ownership of their respective properties, except,
in any such case, to the extent the failure to so comply would not, individually
or in the aggregate, have a material adverse effect on the business, financial
condition or results of operations of Casella and its Restricted Subsidiaries
taken as a whole.

                                      -49-

SECTION 4.08.  WAIVER OF STAY, EXTENSION OR USURY LAWS.

          Each of Casella and each Guarantor covenants (to the extent that it
may lawfully do so) that it will not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury law or other law that would prohibit or forgive
Casella or such Guarantor from paying all or any portion of the principal of
and/or interest on the Notes or the Subsidiary Guarantee of any such Guarantor
as contemplated herein, wherever enacted, now or at any time hereafter in force,
or which may affect the covenants or the performance of this Indenture, and (to
the extent that it may lawfully do so) each hereby expressly waives all benefit
or advantage of any such law, and covenants that it will not hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer
and permit the execution of every such power as though no such law had been
enacted.

SECTION 4.09.  CHANGE OF CONTROL.

          If a Change of Control occurs, each Holder of Notes will have the
right to require Casella to repurchase all or any part (equal to $1,000 or an
integral multiple thereof) of that Holder's Notes pursuant to a Change of
Control Offer (the "CHANGE OF CONTROL OFFER"). In the Change of Control Offer,
Casella will offer to pay an amount in cash (the "CHANGE OF CONTROL PAYMENT")
equal to 101% of the aggregate principal amount of Notes repurchased, plus
accrued and unpaid interest thereon, if any, to the date of purchase. Within 30
days following any Change of Control, Casella will mail a notice to each Holder
describing the transaction or transactions that constitute the Change of Control
and offering to repurchase Notes on the date (the "CHANGE OF CONTROL PAYMENT
DATE") specified in such notice, which date shall be a Business Day no earlier
than 30 days and no later than 60 days from the date such notice is mailed,
pursuant to the procedures required by this Indenture and described in such
notice. Such notice shall state:

          (1)     that the Change of Control Offer is being made pursuant to
     this Section 4.09 and that all Notes tendered and not withdrawn will be
     accepted for payment;

          (2)     the purchase price (including the amount of accrued interest)
     and the Change of Control Payment Date;

          (3)     that any Note not tendered will continue to accrue interest;

          (4)     that, unless Casella defaults in making payment therefor, any
     Note accepted for payment pursuant to the Change of Control Offer shall
     cease to accrue interest after the Change of Control Payment Date;

<Page>

                                      -50-

          (5)     that Holders electing to have a Note purchased pursuant to a
     Change of Control Offer will be required to surrender the Note, with the
     form entitled "Option of Holder to Elect Purchase" on the reverse of the
     Note completed, to the Paying Agent at the address specified in the notice
     prior to the close of business on the third Business Day prior to the
     Change of Control Payment Date;

          (6)     that Holders will be entitled to withdraw their election if
     the Paying Agent receives, not later than the second Business Day prior to
     the Change of Control Payment Date, a telegram, facsimile transmission or
     letter setting forth the name of the Holder, the principal amount of the
     Notes the Holder delivered for purchase and a statement that such Holder is
     withdrawing his election to have such Note purchased;

          (7)     that Holders whose Notes are purchased only in part will be
     issued new Notes in a principal amount equal to the unpurchased portion of
     the Notes surrendered; and

          (8)     the circumstances and relevant facts regarding such Change of
     Control.

          On or before the Change of Control Payment Date, Casella will, to the
extent lawful:

          -    accept for payment all Notes or portions thereof properly
               tendered pursuant to the Change of Control Offer;

          -    deposit with the Paying Agent U.S. Legal Tender sufficient to pay
               the Change of Control Payment in respect of all Notes or portions
               thereof so tendered; and

          -    deliver or cause to be delivered to the Trustee the Notes so
               accepted together with an Officers' Certificate stating the
               aggregate principal amount of Notes or portions thereof being
               purchased by Casella.

          The Paying Agent will promptly mail to each Holder of Notes so
tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered, if any; PROVIDED that each such new Note will be in a
principal amount of $1,000 or an integral multiple thereof.

          Prior to complying with any of the provisions of this Section 4.09,
but in any event within 90 days following a Change of Control, Casella will
either repay all outstanding Senior Debt or obtain the requisite consents, if
any, under all agreements governing outstanding

<Page>

                                      -51-

Senior Debt to permit the repurchase of Notes required by this covenant. Casella
will publicly announce the results of the Change of Control Offer as soon as
practicable after the Change of Control Payment Date.

          Casella will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in this Indenture applicable to a Change of Control Offer made by Casella and
purchases all Notes validly tendered and not withdrawn under such Change of
Control Offer.

          Notwithstanding the foregoing, Casella shall not be required to make a
Change of Control Offer, as provided above, if, in connection with or in
contemplation of any Change of Control, it or a third party has made an offer to
purchase (an "ALTERNATE OFFER") any and all Notes validly tendered at a cash
price equal to or higher than the Change of Control Payment and has purchased
all Notes properly tendered in accordance with the terms of such Alternate
Offer. The Alternate Offer must comply with all the other provisions applicable
to the Change of Control Offer, shall remain, if commenced prior to the Change
of Control, open for acceptance until the consummation of the Change of Control
and must permit Holders to withdraw any tenders of Notes made into the Alternate
Offer until the final expiration or consummation thereof.

          Casella will comply, and will cause any third party making a Change of
Control Offer or an Alternate Offer to comply, with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with a Change of Control Offer or an Alternate Offer. To the extent the
provisions of any applicable securities laws or regulations conflict with the
provisions of this Indenture relating to a Change of Control Offer, Casella will
not be deemed to have breached its obligations under this Indenture by virtue of
complying with such laws or regulations.

SECTION 4.10.  INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK.

          On or after the date of this Indenture (i) Casella will not, and will
not permit any of its Restricted Subsidiaries to, directly or indirectly, incur
any Indebtedness (including Acquired Debt), and (ii) Casella will not issue any
Disqualified Capital Stock and will not permit any of its Restricted
Subsidiaries to issue any shares of preferred stock; PROVIDED that Casella or
any Guarantor may incur Indebtedness (including Acquired Debt), and Casella may
issue Disqualified Capital Stock, if the Consolidated Fixed Charge Coverage
Ratio is at least 2.0 to 1.0 (this proviso, the "COVERAGE RATIO EXCEPTION").

<Page>

                                      -52-

          The first paragraph of this Section 4.10 will not prohibit the
incurrence of any of the following items of Indebtedness (collectively,
"PERMITTED DEBT"):

          (1)     Indebtedness and letters of credit under the Senior Credit
     Facility (with letters of credit being deemed to have a principal amount
     equal to the maximum potential liability of Casella and its Restricted
     Subsidiaries thereunder) in an aggregate principal amount not to exceed
     $375.0 million LESS the aggregate amount of all Net Proceeds of Asset Sales
     applied by Casella or any of its Subsidiaries since the date of this
     Indenture to repay Indebtedness under the Senior Credit Facility pursuant
     to clause (1) of the second paragraph of Section 4.13;

          (2)     the Notes issued on the Issue Date, the Exchange Notes and the
     Subsidiary Guarantees thereof;

          (3)     Capital Lease Obligations and Purchase Money Obligations, and
     Permitted Refinancing Indebtedness thereof, in an aggregate amount not to
     exceed $10.0 million at any time outstanding;

          (4)     Permitted Refinancing Indebtedness in exchange for, or the net
     proceeds of which are used to refinance, (x) Existing Indebtedness or (y)
     Indebtedness incurred under the Coverage Ratio Exception or clause (2) of
     this paragraph or this clause (4);

          (5)     Indebtedness owed by Casella or any of its Restricted
     Subsidiaries to Casella or any of its Restricted Subsidiaries; PROVIDED
     that:

                  (a)  if Casella or any Guarantor is the obligor on such
          Indebtedness, such Indebtedness must be expressly subordinated to the
          prior payment in full in cash of all Obligations with respect to the
          Notes, in the case of Casella, or the Subsidiary Guarantee of such
          Guarantor, in the case of a Guarantor; and

                  (b)  (x) any subsequent issuance or transfer of Equity
          Interests that results in any such Indebtedness being held by a Person
          other than Casella or a Wholly Owned Restricted Subsidiary thereof and
          (y) any sale or other transfer of any such Indebtedness to a Person
          that is not either Casella or a Wholly Owned Restricted Subsidiary
          thereof shall be deemed, in each case, to constitute an incurrence of
          such Indebtedness by Casella or such Restricted Subsidiary, as the
          case may be, that was not permitted by this clause (5);

          (6)     Hedging Obligations with respect to (a) interest rates on any
     Indebtedness that is permitted by the terms of this Indenture to be
     outstanding, (b) foreign currency

     rubber, plastics or other recycled products or (d) the price of fuel
     required for the operations of the businesses of Casella and its Restricted
     Subsidiaries; PROVIDED that (i) any such Hedging Obligation of the type
     described in clauses (b) through (d) will be permitted by this clause (6)
     only if it was entered into to protect Casella and its Restricted
     Subsidiaries from fluctuations in foreign currency exchange rates, the
     prices of recycled paper, fiber, aluminum, tin, glass, rubber, plastics or
     other recycled products or fuel covered by such agreements, as applicable,
     and not for speculative purposes, (ii) in the case of Hedging Obligations
     of the type described in clause (a) above, any such Hedging Obligations
     will be permitted by this clause (6) only to the extent the notional
     principal amount of such Hedging Obligations, when incurred, does not
     exceed the principal amount of the Indebtedness to which such Hedging
     Obligations relate and (iii) in the case of Hedging Obligations of the type
     described in clause (b) above, such Hedging Obligations do not increase the
     Indebtedness of Casella and its Restricted Subsidiaries outstanding other
     than as a result of fluctuations in foreign currency exchange rates or by
     reason of fees, indemnities and compensation payable thereunder;

          (7)     obligations in the ordinary course of business in respect of
     workers' compensation claims, self-insurance obligations, performance,
     surety and similar bonds and completion bonds and bid guarantees with
     respect to the assets or business of Casella or any of its Restricted
     Subsidiaries;

          (8)     (x) the Guarantee by Casella or any Guarantor of Indebtedness
     of Casella or a Guarantor and (y) the guarantee by any Restricted
     Subsidiary that is not a Guarantor of Indebtedness of any other Restricted
     Subsidiary that is not a Guarantor; PROVIDED that, in each case, the
     Indebtedness being guaranteed is permitted to be incurred by another
     provision of this Indenture;

          (9)     indemnification, adjustment of purchase price or similar
     obligations, in each case, incurred or assumed in connection with the
     disposition of any business or assets of Casella or any of its Restricted
     Subsidiaries or Capital Stock of any of its Restricted Subsidiaries;
     PROVIDED that the maximum aggregate liability in respect of all of such
     obligations outstanding under this clause (9) shall at no time exceed the
     gross proceeds including non-cash proceeds (the fair market value of such
     non-cash proceeds being measured at the time received and without giving
     effect to any subsequent changes in value) actually received by Casella and
     its Restricted Subsidiaries in connection with such dispositions;

          (10)    Acquired Debt incurred by the debtor prior to the time that
     the debtor thereunder was acquired by or merged into Casella or any of its
     Subsidiaries, or prior to the time that the related asset was acquired by
     Casella or any of its Subsidiaries, and

<Page>

                                      -54-

     was not incurred in connection with, or in contemplation of, such
     acquisition or merger, and Permitted Refinancing Indebtedness thereof, in
     an aggregate amount not to exceed $10.0 million at any time outstanding;

          (11)    Indebtedness arising from the honoring by a bank or other
     financial institution of a check, draft or similar instrument inadvertently
     (except in the case of daylight overdrafts) drawn against insufficient
     funds; PROVIDED that such Indebtedness is extinguished within five business
     days of incurrence; and

          (12)    additional Indebtedness in an aggregate amount not to exceed
     $10.0 million at any time outstanding.

          Notwithstanding any other provision in this Section 4.10, the maximum
amount of Indebtedness that Casella or any of its Restricted Subsidiaries may
incur pursuant to this covenant shall not be deemed to be exceeded as a result
of fluctuations in exchange rates of currencies. The outstanding principal
amount of any particular Indebtedness shall be counted only once and any
obligation arising under any Guarantee, Lien, letter of credit or similar
instrument supporting such Indebtedness shall be disregarded, so long as the
obligor is permitted to incur such obligation. For purposes of determining
compliance with this Section 4.10, in the event that an item of proposed
Indebtedness meets the criteria of more than one of the categories of Permitted
Debt described in clauses (1) through (12) above, or is entitled to be incurred
pursuant to the Coverage Ratio Exception, Casella will be permitted to divide
and classify such item of Indebtedness on the date of its incurrence in any
manner that complies with this covenant (PROVIDED that all Indebtedness
outstanding under the Senior Credit Facility on the Issue Date shall be deemed
to have been incurred pursuant to clause (1) of the preceding paragraph).

SECTION 4.11.  RESTRICTED PAYMENTS.

          Casella will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly:

          (i)     declare or pay any dividend or make any other payment or
     distribution on account of Casella's or any of its Restricted Subsidiaries'
     Equity Interests (including, without limitation, any payment in connection
     with any merger or consolidation involving Casella or any of its Restricted
     Subsidiaries) or to the direct or indirect holders of Casella's or any of
     its Restricted Subsidiaries' Equity Interests in their capacity as such
     (other than dividends or distributions payable solely in Qualified Capital
     Stock or dividends or distributions payable to Casella or any of its
     Restricted Subsidiaries);

<Page>

                                      -55-

          (ii)    purchase, redeem or otherwise acquire or retire for value
     (including, without limitation, in connection with any merger or
     consolidation involving Casella or any of its Restricted Subsidiaries) any
     Equity Interests of Casella or any direct or indirect parent of Casella or
     any Restricted Subsidiary of Casella (other than any such Equity Interests
     owned by Casella or any of its Restricted Subsidiaries);

          (iii)   make any payment on or with respect to, or purchase, redeem,
     prepay, decrease, defease or otherwise acquire or retire for value, any
     Indebtedness that is expressly subordinated in right of payment to the
     Notes or any Subsidiary Guarantee, except (x) any payment of interest or
     principal at the Stated Maturity thereof, (y) any payment made with
     Qualified Capital Stock and (z) any payment made to Casella or any of its
     Restricted Subsidiaries; or

          (iv)    make any Restricted Investment

(all such payments and other actions set forth in clauses (i) through (iv) above
being collectively referred to as "RESTRICTED PAYMENTS"), unless, at the time of
and after giving effect to such Restricted Payment:

          (1)     no Default has occurred and is continuing or would occur as a
     consequence thereof;

          (2)     Casella would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the applicable Four Quarter Period, have been
     permitted to incur at least $1.00 of additional Indebtedness pursuant to
     the Coverage Ratio Exception; and

          (3)     such Restricted Payment, together with the aggregate amount of
     all other Restricted Payments made by Casella and its Restricted
     Subsidiaries after the date of this Indenture (excluding Restricted
     Payments permitted by clauses (2), (3), (4) (only to the extent payable to
     Casella or any of its Restricted Subsidiaries), (5), (7) and (8) of the
     next succeeding paragraph), is less than the sum (the "BASKET"), without
     duplication, of

                  (a)  50% of the Consolidated Net Income of Casella for the
          period (taken as one accounting period) from the beginning of the
          first fiscal quarter commencing after the Issue Date to the end of
          Casella's most recently ended fiscal quarter for which internal
          financial statements are available at the time of such Restricted
          Payment (or, if such Consolidated Net Income for such period is a
          deficit, less 100% of such deficit), PLUS

                                      -56-

                  (b)  100% of the aggregate net cash proceeds received by
          Casella since the Issue Date from the issuance and sale of Qualified
          Capital Stock or from the issuance and sale of convertible or
          exchangeable Disqualified Capital Stock or Indebtedness of Casella or
          any of its Restricted Subsidiaries that has been converted into or
          exchanged for Qualified Capital Stock (other than any issuance and
          sale to a Subsidiary of Casella), LESS the amount of any cash, or the
          fair market value of any other assets, distributed by Casella or any
          of its Restricted Subsidiaries upon such conversion or exchange (other
          than to Casella or any of its Restricted Subsidiaries), PLUS

                  (c)  to the extent not otherwise included in the calculation
          of Consolidated Net Income for purposes of clause (a) above, 100% of
          (x) any amount received in cash by Casella or any of its Restricted
          Subsidiaries as dividends, distributions or return of capital from, or
          payment of interest or principal on any loan or advance to, and (y)
          the aggregate net cash proceeds received by Casella or any of its
          Restricted Subsidiaries upon the sale or other disposition of, the
          investee (other than an Unrestricted Subsidiary of Casella) of any
          Investment made by Casella and its Restricted Subsidiaries since the
          Issue Date; PROVIDED that the foregoing sum shall not exceed, in the
          case of any investee, the aggregate amount of Investments previously
          made (and treated as a Restricted Payment) by Casella or any of its
          Restricted Subsidiaries in such investee subsequent to the Issue Date;
          PLUS

                  (d)  to the extent not otherwise included in the calculation
          of Consolidated Net Income for purposes of clause (a) above, 100% of
          (x) any amount received in cash by Casella or any of its Restricted
          Subsidiaries as dividends, distributions or return of capital from, or
          payment of interest or principal on any loan or advance to, or upon
          the sale or other disposition of the Capital Stock of, an Unrestricted
          Subsidiary of Casella and (y) the fair market value of the net assets
          of an Unrestricted Subsidiary of Casella, at the time such
          Unrestricted Subsidiary is redesignated as a Restricted Subsidiary or
          is merged, consolidated or amalgamated with or into, or is liquidated
          into, Casella or any of its Restricted Subsidiaries, multiplied by
          Casella's proportionate interest in such Subsidiary; PROVIDED that the
          foregoing sum shall not exceed, in the case of any Unrestricted
          Subsidiary, the aggregate amount of Investments previously made (and
          treated as a Restricted Payment) by Casella or any of its Restricted
          Subsidiaries in such Unrestricted Subsidiary subsequent to the Issue
          Date; PLUS

                  (e)  to the extent not otherwise included in the calculation
          of Consolidated Net Income for purposes of clause (a) above, 100% of
          the amount of
<Page>

                                      -57-

          any Investment made (and treated as a Restricted Payment) since the
          Issue Date in a Person that subsequently becomes a Restricted
          Subsidiary of Casella.

          The preceding provisions will not prohibit:

          (1)     the payment of any dividend within 60 days after the date of
     declaration thereof, if at said date of declaration such payment would have
     complied with the provisions of this Indenture;

          (2)     the redemption, repurchase, retirement, defeasance or other
     acquisition of (a) any Indebtedness of Casella or any Guarantor that is
     expressly subordinated in right of payment to the Notes or any Subsidiary
     Guarantee or (b) any Equity Interests of Casella or any of its Restricted
     Subsidiaries in exchange for, or out of the net cash proceeds of the
     substantially concurrent issuance and sale (other than to a Subsidiary of
     Casella) of, Qualified Capital Stock; PROVIDED that the amount of any such
     net cash proceeds that are utilized for any such redemption, repurchase,
     retirement, defeasance or other acquisition shall not increase the Basket;

          (3)     the redemption, repurchase, retirement, defeasance or other
     acquisition of Indebtedness of Casella or any Guarantor which is expressly
     subordinated in right of payment to the Notes or any Subsidiary Guarantee
     with the net cash proceeds from an incurrence of Permitted Refinancing
     Indebtedness;

          (4)     the payment of any dividend or other distribution of earnings
     and profits by a Restricted Subsidiary of Casella to the holders of all of
     its Equity Interests on a PRO RATA basis or to the holders of the Equity
     Interests of GreenFiber in accordance with the terms of the limited
     liability company agreement governing GreenFiber, as in effect at the time
     of such payment;

          (5)     the repurchase of Equity Interests deemed to occur upon the
     exercise of stock options if such Equity Interests represent a portion of
     the exercise price thereof;

          (6)     as long as no Default has occurred and is continuing or would
     be caused thereby, the redemption, repurchase or other acquisition of
     Equity Interests constituting restricted stock repurchased from an employee
     of Casella or any of its Restricted Subsidiaries in connection with the
     termination of employment of such employee, in an amount not to exceed the
     net cash proceeds received from such terminated employee upon issuance of
     such Equity Interests;

          (7)     (i) the redemption in cash on or after August 11, 2007 of the
     shares of Series A Redeemable Convertible Preferred Stock outstanding on
     the date hereof pursuant

<Page>

                                      -58-

     to the mandatory redemption provisions of the Series A Convertible
     Preferred Stock and (ii) the payment of dividends on the Series A
     Redeemable Convertible Preferred Stock by the increase, at or after the
     relevant dividend payment dates, in the liquidation preference thereof
     equal to the amount of such dividends; and

          (8)     Restricted Payments not to exceed $5.0 million in the
     aggregate since the Issue Date.

          The amount of all Restricted Payments (other than cash) shall be the
fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by Casella or such Restricted
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any assets or securities having a fair market value in excess of
$5.0 million that are required to be valued by this covenant shall be determined
in good faith by the Board of Directors, whose resolution with respect thereto
shall be delivered to the Trustee. The Board of Directors' determination must be
based upon an opinion or appraisal issued by an accounting, appraisal or
investment banking firm of national standing if the fair market value exceeds
$10.0 million. Not later than the date of making any Restricted Payment, Casella
shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by this Section 4.11 were computed, together with a copy
of any fairness opinion or appraisal required by this Indenture.

          In determining whether any Restricted Payment is permitted by this
Section 4.11, Casella may allocate or reallocate all or any portion of such
Restricted Payment between clauses (6) and (8) of the second paragraph of this
Section 4.11 or between such clauses and the Basket; PROVIDED that at the time
of such allocation or reallocation, all such Restricted Payments, or allocated
portions thereof, would be permitted under such provisions.

SECTION 4.12.  LIENS.

          Casella will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien of any kind securing Indebtedness, Attributable Debt or trade
payables on any asset now owned or hereafter acquired, except Permitted Liens,
unless all payments due under this Indenture and the Notes are secured on an
equal and ratable basis with the obligation so secured until such time as such
is no longer secured by a Lien; PROVIDED that if such obligation is by its terms
expressly subordinated to the Notes or any Subsidiary Guarantee, the Lien
securing such obligation shall be subordinate and junior to the Lien securing
the Notes and the Subsidiary Guarantees with the same relative priority as such
subordinate or junior obligation shall have with respect to the Notes and the
Subsidiary Guarantees.

SECTION 4.13.  ASSET SALES.

          Casella will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless:

          -    Casella or such Restricted Subsidiary, as the case may be,
               receives consideration at the time of such Asset Sale at least
               equal to the fair market value of the assets or Equity Interests
               issued, sold or otherwise disposed of;

          -    such fair market value, if in excess of $5.0 million, is
               determined in good faith by Casella's Board of Directors and
               evidenced by a resolution of the Board of Directors set forth in
               an Officers' Certificate delivered to the Trustee; and

          -    at least 75% of the consideration therefor received by Casella or
               such Restricted Subsidiary is in the form of cash or Cash
               Equivalents and is received at the time of such Asset Sale. For
               purposes of this provision, each of the following shall be deemed
               to be cash:

                       (a)  the amount of any liabilities shown on Casella's or
                  such Restricted Subsidiary's most recent balance sheet (other
                  than contingent liabilities and liabilities that are by their
                  terms subordinated to the Notes or any Subsidiary Guarantee)
                  that are assumed by another Person and from which Casella and
                  its Restricted Subsidiaries are released from further
                  liability; and

                       (b)  any securities, notes or other obligations received
                  by Casella or any such Restricted Subsidiary from such
                  transferee that are promptly (subject to ordinary settlement
                  periods) converted by Casella or such Restricted Subsidiary
                  into cash (to the extent of the cash received in that
                  conversion).

          Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, Casella may apply such Net Proceeds at its option:

          (1)     to repay Senior Debt and, if the Senior Debt repaid is
     revolving credit Indebtedness, to permanently reduce a corresponding amount
     of commitments with respect thereto;

          (2)     to make an investment in or expenditures for assets (excluding
     securities other than Capital Stock of any Person that (A) is or becomes a
     Guarantor or (B) is

<Page>

                                      -60-

     merged, consolidated or amalgamated with or into, or transfers all or
     substantially all of its assets to, or is liquidated into, Casella or any
     Guarantor) that replace the assets that were the subject of the Asset Sale
     or that will be used in the Permitted Business ("REPLACEMENT ASSETS");
     and/or

          (3)     to redeem Notes pursuant to Section 5 or Section 6 of the
     Notes.

Pending the final application of any such Net Proceeds, Casella may temporarily
reduce revolving credit borrowings or otherwise invest such Net Proceeds in any
manner that is not prohibited by this Indenture.

          Any Net Proceeds from Asset Sales that are not applied as provided in
the preceding paragraph will constitute "EXCESS PROCEEDS." When the aggregate
amount of Excess Proceeds exceeds $10.0 million, Casella will make an offer to

          -    all Holders of Notes and

          -    all holders of other Indebtedness that ranks PARI PASSU with the
               Notes containing provisions similar to those set forth in this
               Indenture with respect to offers to purchase or redeem with the
               proceeds of sales of assets

to purchase (an "ASSET SALE OFFER") the maximum principal amount of Notes and
such other PARI PASSU Indebtedness that may be purchased out of the Excess
Proceeds (the "ASSET SALE OFFER AMOUNT"). The offer price for Notes in any Asset
Sale Offer will be equal to 100% of the principal amount of Notes purchased,
plus accrued and unpaid interest, if any, to the date of purchase (the "ASSET
SALE PAYMENT"), and will be payable in U.S. Legal Tender. If the aggregate
principal amount of Notes and such other PARI PASSU Indebtedness tendered into
such Asset Sale Offer exceeds the amount of Excess Proceeds, Casella shall
select the Notes and such other PARI PASSU Indebtedness to be purchased on a PRO
RATA basis. Upon completion of each Asset Sale Offer, the amount of Excess
Proceeds shall be reset at zero. Accordingly, if any Excess Proceeds remain
after consummation of an Asset Sale Offer, Casella may use such Excess Proceeds
for any purpose not otherwise prohibited by this Indenture.

          When any non-cash consideration received by Casella or any of its
Restricted Subsidiaries in connection with any Asset Sale is converted into or
sold or otherwise disposed of for cash or Cash Equivalents, such cash and Cash
Equivalents must be applied in accordance with this Section 4.13.

          Upon the commencement of an Asset Sale Offer, Casella shall send, by
first class mail, a notice to the Trustee and to each Holder at its registered
address. The notice shall contain all instructions and materials necessary to
enable such Holder to tender Notes

<Page>

                                      -61-

pursuant to the Asset Sale Offer. Any Asset Sale Offer shall be made to all
Holders. The notice, which shall govern the terms of the Asset Sale Offer, shall
state:

          (1)     that the Asset Sale Offer is being made pursuant to this
     Section 4.13;

          (2)     the Asset Sale Offer Amount, the Asset Sale Payment and the
     date on which Notes tendered and accepted for payment shall be purchased,
     which date shall be at least 30 days and no later than 60 days from the
     date such notice is mailed (the "ASSET SALE PAYMENT DATE");

          (3)     that any Notes not tendered or accepted for payment shall
     continue to accrete or accrue interest;

          (4)     that, unless Casella defaults in making such payment, any
     Notes accepted for payment pursuant to the Asset Sale Offer shall cease to
     accrete or accrue interest after the Asset Sale Payment Date;

          (5)     that Holders electing to have a Note purchased pursuant to the
     Asset Sale Offer may only elect to have all of such Note purchased and may
     not elect to have only a portion of such Note purchased;

          (6)     that Holders electing to have a Note purchased pursuant to any
     Asset Sale Offer shall be required to surrender the Note, with the form
     entitled "Option of Holder to Elect Purchase" on the reverse of the Notes
     completed, or transfer by book-entry transfer, to Casella, a depository, if
     appointed by Casella, or the Paying Agent at the address specified in the
     notice at least three days before the Asset Sale Payment Date;

          (7)     that Holders shall be entitled to withdraw their election if
     Casella, the Depository or the Paying Agent, as the case may be, receives,
     not later than the Asset Sale Payment Date, a notice setting forth the name
     of the Holder, the principal amount of the Note the Holder delivered for
     purchase and a statement that such Holder is withdrawing his election to
     have such Note purchased;

          (8)     that, if the aggregate principal amount of Notes surrendered
     by Holders exceeds the Asset Sale Offer Amount, Casella shall select the
     Notes to be purchased on a PRO RATA basis (with such adjustments as may be
     deemed appropriate by Casella so that only Notes in denominations of
     $1,000, or integral multiples thereof, shall be purchased); and

<Page>

                                      -62-

          (9)     that Holders whose Notes were purchased only in part shall be
     issued new Notes equal in principal amount to the unpurchased portion of
     the Notes surrendered (or transferred by book-entry transfer).

          On the Asset Sale Payment Date, Casella shall, to the extent lawful:
(1) accept for payment all Notes or portions thereof properly tendered pursuant
to the Asset Sale Offer; (2) deposit with the Paying Agent U.S. Legal Tender
sufficient to pay the Asset Sale Payment in respect of all Notes or portions
thereof so tendered; and (3) deliver or cause to be delivered to the Trustee the
Notes so accepted together with an Officers' Certificate stating the aggregate
principal amount of Notes or portions thereof being repurchased by Casella.
Casella shall publicly announce the results of the Asset Sale Offer on the Asset
Sale Payment Date.

          The Paying Agent shall promptly mail to each Holder of Notes so
tendered the Asset Sale Payment for such Notes, and the Trustee shall promptly
authenticate pursuant to an Authentication Order and mail (or cause to be
transferred by book entry) to each Holder a new Note equal in principal amount
to any unrepurchased portion of the Notes surrendered, if any; PROVIDED that
each such new Note shall be in a principal amount of $1,000 or an integral
multiple thereof. However, if the Asset Sale Payment Date is on or after an
interest record date and on or before the related interest payment date, any
accrued and unpaid interest shall be paid to the Person in whose name a Note is
registered at the close of business on such record date, and no additional
interest shall be payable to Holders who tender Notes pursuant to the Asset Sale
Offer.

          Casella will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with an Asset Sale
Offer. To the extent the provisions of any applicable securities laws or
regulations conflict with the provisions of this Indenture relating to an Asset
Sale Offer, Casella will not be deemed to have breached its obligations under
this Indenture by virtue of complying with such laws or regulations.

SECTION 4.14.  TRANSACTIONS WITH AFFILIATES.

          Casella will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, make any payment to, or sell, lease,
transfer or otherwise dispose of any of its properties or assets to, or purchase
any property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any of its Affiliates (each, an "AFFILIATE TRANSACTION"), unless:

          (1)     such Affiliate Transaction is on terms that are no less
     favorable to Casella or the relevant Restricted Subsidiary than those that
     would have been obtained

<Page>

                                      -63-

     in a comparable transaction by Casella or such Restricted Subsidiary with
     an unrelated Person; and

          (2)     Casella delivers to the Trustee:

                  (a)  with respect to any Affiliate Transaction or series of
          related Affiliate Transactions involving aggregate consideration in
          excess of $2.0 million, a resolution of the Board of Directors of
          Casella set forth in an Officers' Certificate certifying that such
          Affiliate Transaction complies with this covenant and that such
          Affiliate Transaction has been approved by a majority of the
          Disinterested Directors of Casella, if there are any such
          Disinterested Directors; and

                  (b)  with respect to any Affiliate Transaction or series of
          related Affiliate Transactions involving aggregate consideration in
          excess of $10.0 million, or in excess of $2.0 million if such
          transaction has not been approved by a majority of the Disinterested
          Directors or if at such time there are no Disinterested Directors, an
          opinion as to the fairness of such Affiliate Transaction from a
          financial point of view issued by an accounting, appraisal or
          investment banking firm of national standing.

          The following items shall not be deemed to be Affiliate Transactions
and, therefore, will not be subject to the provisions of the preceding
paragraph:

          (1)     transactions exclusively between or among Casella and/or one
     or more of its Restricted Subsidiaries; PROVIDED, in each case, such
     transaction is not otherwise prohibited by this Indenture and that no
     Affiliate of Casella (other than a Restricted Subsidiary) owns any Equity
     Interests in any Restricted Subsidiary that is a party to such transaction;

          (2)     any agreement in effect on the Issue Date as in effect on the
     Issue Date or as thereafter amended in a manner which is, taken as a whole,
     in the good faith judgment of the Board of Directors of Casella not
     materially less favorable to Casella or such Restricted Subsidiary than the
     original agreement as in effect on the Issue Date;

          (3)     any employment, compensation, benefit or indemnity agreements,
     arrangements or plans in respect of any officer, director, employee or
     consultant of Casella or any of its Restricted Subsidiaries entered into in
     the ordinary course of business and approved by the Board of Directors of
     Casella;

<Page>

                                      -64-

          (4)     loans and advances permitted by clause (6) of the definition
     of "Permitted Investments";

          (5)     transactions between Casella or any of its Restricted
     Subsidiaries and GreenFiber; PROVIDED, in each case, that (i) such
     transaction (a) is on terms that are no less favorable to Casella or the
     relevant Restricted Subsidiary than those that would have been obtained in
     a comparable transaction by Casella or such Restricted Subsidiary with an
     unrelated Person and (b) is not otherwise prohibited by this Indenture and
     (ii) no Affiliate of Casella (other than a Restricted Subsidiary) owns any
     Equity Interests in any Person that is a party to such transaction;

          (6)     the issuance and sale of Qualified Capital Stock; and

          (7)     Restricted Payments (other than Investments) that are
     permitted by Section 4.11.

SECTION 4.15.  DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

          Casella will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to:

          (1)     pay dividends or make any other distributions on or in respect
     of its Equity Interests to Casella or any of Casella's Restricted
     Subsidiaries, or with respect to any other interest or participation in, or
     measured by, its profits, or pay any indebtedness owed to Casella or any of
     Casella's Restricted Subsidiaries;

          (2)     make loans or advances to Casella or any of Casella's
     Restricted Subsidiaries; or

          (3)     transfer any of its properties or assets to Casella or any of
     Casella's Restricted Subsidiaries.

          However, the preceding restrictions will not apply to encumbrances or
restrictions existing under or by reason of:

          (1)     the Senior Credit Facility or any Existing Indebtedness, in
     each case, as in effect on the date of this Indenture and any amendments or
     refinancings thereof; PROVIDED that such amendments or refinancings are not
     materially more restrictive, taken as a whole, with respect to such
     dividend and other restrictions than those contained in the Senior Credit
     Facility or such Existing Indebtedness, as in effect on the date of this
     Indenture;

<Page>

                                      -65-

          (2)     this Indenture and the Notes;

          (3)     applicable law, rule, regulation or order of any governmental
     authority;

          (4)     any instrument governing Indebtedness or Capital Stock of a
     Person acquired by Casella or any of its Restricted Subsidiaries as in
     effect at the time of such acquisition (except to the extent such
     Indebtedness was incurred in connection with or in contemplation of such
     acquisition), which encumbrance or restriction is not applicable to any
     Person, or the properties or assets of any Person, other than the Person,
     or the property or assets of the Person, so acquired; PROVIDED that, in the
     case of Indebtedness, such Indebtedness was permitted by the terms of this
     Indenture to be incurred;

          (5)     customary non-assignment provisions (and sublease
     restrictions) in leases entered into in the ordinary course of business and
     consistent with past practices;

          (6)     Purchase Money Obligations that impose restrictions only on
     the property acquired of the nature described in clause (3) of the
     preceding paragraph;

          (7)     any agreement for the sale or other disposition of a
     Restricted Subsidiary that restricts distributions by such Restricted
     Subsidiary pending its sale or other disposition; PROVIDED that such sale
     or disposition is made in compliance with Section 4.13;

          (8)     Permitted Refinancing Indebtedness; PROVIDED that such
     dividend and other restrictions contained in the agreements governing such
     Permitted Refinancing Indebtedness are not materially more restrictive,
     taken as a whole, than those contained in the agreements governing the
     Indebtedness being refinanced;

          (9)     Liens securing Indebtedness otherwise permitted to be incurred
     pursuant to Section 4.12 that limit the right of Casella or any of its
     Restricted Subsidiaries to dispose of the assets subject to such Lien;

          (10)    provisions with respect to the disposition or distribution of
     assets or property in joint venture agreements and other similar agreements
     entered into in the ordinary course of business;

          (11)    customary restrictions on cash or other deposits or net worth
     imposed by customers or government authorities under contracts or other
     agreements entered into in the ordinary course of business; and

<Page>

                                      -66-

          (12)    any agreement relating to a Sale and Leaseback Transaction or
     Capital Lease Obligation, in each case, otherwise permitted by this
     Indenture, but only on the property subject to such transaction or lease
     and only to the extent that such restrictions or encumbrances are customary
     with respect to a Sale and Leaseback Transaction or capital lease.

SECTION 4.16.  ADDITIONAL SUBSIDIARY GUARANTEES.

          If Casella or any of its Restricted Subsidiaries transfers, acquires
or creates another Restricted Subsidiary (other than any Foreign Subsidiary)
after the date of this Indenture or transfers or causes to be transferred, in
any one transaction or a series of related transactions, any assets in excess of
$1,000 to any Restricted Subsidiary (other than a Foreign Subsidiary or the
Captive Insurance Subsidiary) that is not a Guarantor, or designates any
Unrestricted Subsidiary (other than a Foreign Subsidiary) as a Restricted
Subsidiary, then that newly acquired, created, capitalized or designated
Restricted Subsidiary must become a Guarantor and shall, within ten business
days of the date on which it was so acquired, created, capitalized or
designated:

          -    execute and deliver to the Trustee a supplemental indenture in
               form reasonably satisfactory to the Trustee pursuant to which
               such Restricted Subsidiary shall unconditionally guarantee all of
               Casella's obligations under the Notes and this Indenture on the
               terms set forth in this Indenture and

          -    deliver to the Trustee an Opinion of Counsel that such
               supplemental indenture has been duly authorized, executed and
               delivered by such Restricted Subsidiary and constitutes a valid
               and legally binding and enforceable obligation of such Restricted
               Subsidiary, subject to customary exceptions.

Thereafter, such Restricted Subsidiary shall be a Guarantor for all purposes of
this Indenture.

          Notwithstanding the preceding paragraph, any Subsidiary Guarantee will
provide by its terms that it will be automatically and unconditionally released
and discharged under the circumstances set forth in Section 11.05. The form of
the Subsidiary Guarantee is attached hereto as EXHIBIT E.

SECTION 4.17.  NO SENIOR SUBORDINATED DEBT.

          Casella will not, directly or indirectly, incur any Indebtedness that
is, or purports to be, subordinate or junior in right of payment to any Senior
Debt of Casella and senior in any respect in right of payment to the Notes. No
Guarantor will, directly or indirectly, incur any Indebtedness that is, or
purports to be, subordinate or junior in right of payment to any

<Page>

                                      -67-

Senior Debt of such Guarantor and senior in any respect in right of payment to
such Guarantor's Subsidiary Guarantee. For purposes hereof, unsecured
Indebtedness shall not be deemed to be subordinate or junior to secured
Indebtedness solely because it is unsecured, and Indebtedness that is not
Guaranteed by a particular Person shall not be deemed to be subordinate or
junior to Indebtedness solely because it is not so Guaranteed.

SECTION 4.18.  REPORTS TO HOLDERS.

          Whether or not required by the Commission, so long as any Notes are
outstanding, Casella will furnish to the Holders of Notes, within the time
periods specified in the Commission's rules and regulations:

          (1)     all quarterly and annual financial information that would be
     required to be contained in a filing with the Commission on Forms 10-Q and
     10-K if Casella were required to file such Forms, including a "Management's
     Discussion and Analysis of Financial Condition and Results of Operations"
     and, with respect to the annual information only, a report on the annual
     financial statements by Casella's certified independent accountants; and

          (2)     all current reports that would be required to be filed with
     the Commission on Form 8-K if Casella were required to file such reports.

          If Casella has designated any of its Subsidiaries as Unrestricted
Subsidiaries, then the quarterly and annual financial information required by
the preceding paragraph shall include a reasonably detailed presentation, either
on the face of the financial statements or in the footnotes thereto, and in
Management's Discussion and Analysis of Financial Condition and Results of
Operations, of the financial condition and results of operations of Casella and
its Restricted Subsidiaries separate from the financial condition and results of
operations of Casella's Unrestricted Subsidiaries.

          In addition, whether or not required by the Commission, Casella will
file a copy of all of the information and reports referred to in clauses (1) and
(2) above with the Commission for public availability within the time periods
specified in the Commission's rules and regulations (unless the Commission will
not accept such a filing) and make such information available to securities
analysts and prospective investors upon request.

          Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including Casella's compliance
with any of its covenants hereunder (as to which the Trustee is entitled to rely
exclusively on Officers' Certificates).

SECTION 4.19.  DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES.

          The Board of Directors of Casella may designate (a "DESIGNATION") any
Restricted Subsidiary to be an Unrestricted Subsidiary if such Designation would
not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, all outstanding Investments owned by Casella and its Restricted
Subsidiaries in the Subsidiary so designated will be deemed to be an Investment
made as of the time of such Designation and will reduce the amount available for
Restricted Payments under the first paragraph of Section 4.11 or for Permitted
Investments, as applicable. All such outstanding Investments will be valued at
their fair market value at the time of such Designation in accordance with the
provisions of the second to last paragraph of Section 4.11. Such Designation
will be permitted only if such Investment would be a Permitted Investment or
otherwise would at the time of such Designation not be prohibited under Section
4.11.

          The Board of Directors of Casella may revoke any Designation of a
Subsidiary of Casella as an Unrestricted Subsidiary (a "REVOCATION"); PROVIDED
that

          (a)     no Default exists at the time of or after giving effect to
     such Revocation; and

          (b)     all Liens and Indebtedness of such Unrestricted Subsidiary
     outstanding immediately after such Revocation would, if incurred at such
     time, have been permitted to be incurred (and shall be deemed to have been
     incurred) for all purposes of this Indenture.

          Any such Designation or Revocation by the Board of Directors of
Casella after the Issue Date shall be evidenced to the Trustee by promptly
filing with the Trustee a copy of the resolution of the Board of Directors of
Casella giving effect to such Designation or Revocation and an Officers'
Certificate certifying that such Designation or Revocation complied with the
foregoing provisions.

SECTION 4.20.  SALE AND LEASEBACK TRANSACTIONS.

          Casella will not, and will not permit any of its Restricted
Subsidiaries to, enter into any Sale and Leaseback Transaction; PROVIDED that
Casella or any Restricted Subsidiary of Casella that is a Guarantor may enter
into a Sale and Leaseback Transaction if:

          (1)     Casella or that Guarantor, as applicable, could have (a)
     incurred Indebtedness in an amount equal to the Attributable Debt relating
     to such Sale and Leaseback Transaction pursuant to Section 4.10 and (b)
     incurred a Lien to secure such Indebtedness pursuant to Section 4.12;

<Page>

                                      -69-

          (2)     the gross cash proceeds of such Sale and Leaseback Transaction
     are at least equal to the fair market value, as determined in good faith by
     the Board of Directors and set forth in an Officers' Certificate delivered
     to the Trustee, of the assets that are the subject of such Sale and
     Leaseback Transaction; and

          (3)     the transfer of assets in such Sale and Leaseback Transaction
     is permitted by, and Casella applies the proceeds of such transaction in
     compliance with, Section 4.13 (unless the sale of such assets would not
     constitute an Asset Sale under the definition of "Asset Sale").

SECTION 4.21.  LIMITATION ON ISSUANCES AND SALES OF EQUITY INTERESTS IN WHOLLY
               OWNED SUBSIDIARIES.

          Casella will not, and will not permit any of its Restricted
Subsidiaries to, transfer, convey, sell, lease or otherwise dispose of any
Equity Interests in any Wholly Owned Restricted Subsidiary of Casella to any
Person (other than Casella or a Wholly Owned Restricted Subsidiary of Casella),
unless the transfer, conveyance, sale, lease or other disposition is of all the
Equity Interests in such Wholly Owned Restricted Subsidiary and the Net Proceeds
from such transfer, conveyance, sale, lease or other disposition are applied in
accordance with the provisions of Section 4.13. In addition, Casella will not
permit any of its Wholly Owned Restricted Subsidiaries to issue any of their
Equity Interests (other than, if necessary, shares of their Capital Stock
constituting directors' qualifying shares) to any Person other than Casella or a
Wholly Owned Restricted Subsidiary of Casella. The prohibitions of this Section
4.21 will not apply with respect to the Equity Interests of GreenFiber or any of
its Subsidiaries or its direct parent if or when GreenFiber becomes a Wholly
Owned Restricted Subsidiary of Casella.

SECTION 4.22.  BUSINESS ACTIVITIES.

          Casella will not, and will not permit any Restricted Subsidiary to,
engage in any business other than Permitted Businesses.

SECTION 4.23.  PAYMENTS FOR CONSENT.

          Casella will not, and will not permit any of its Subsidiaries to,
directly or indirectly, pay or cause to be paid any consideration to or for the
benefit of any Holder of Notes for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of this Indenture or the Notes
UNLESS such consideration is offered to be paid and is paid to all Holders of
the Notes that consent, waive or agree to amend in the time frame set forth in
the solicitation documents relating to such consent, waiver or amendment.

     Person formed by or surviving any such consolidation or merger (if other

     corporation organized under the laws of the United States, any State
     thereof or the District of Columbia;

          (2)     the Surviving Person assumes all the obligations of Casella
     under the Notes, this Indenture and the Exchange and Registration Rights
     Agreement pursuant to agreements reasonably satisfactory to the Trustee;

          (3)     immediately after such transaction no Default exists
     (including, without limitation, after giving effect to any Indebtedness or
     Liens incurred, assumed or granted in connection with or in respect of such
     transaction); and

          (4)     Casella or the Surviving Person:

                  (x)  will have a Consolidated Net Worth immediately after the
          transaction equal to or greater than the Consolidated Net Worth of
          Casella immediately preceding the transaction; and

                  (y)  will be permitted to incur at least $1.00 of additional
          Indebtedness pursuant to the Coverage Ratio Exception.

The foregoing clauses (3) and (4) shall not apply to (a) a merger or
consolidation of any Restricted Subsidiary with or into Casella or (b) a
transaction solely for the purpose of and with the effect of reincorporating
Casella in another jurisdiction and/or forming a holding company to hold all of
the Capital Stock of Casella or forming an intermediate holding company to hold
all of the Capital Stock of Casella's Subsidiaries.

<Page>

                                      -71-

          In the event of any transaction described in and complying with the
conditions listed in the preceding paragraph in which Casella is not the
continuing corporation, the successor Person formed or remaining shall succeed
to, and be substituted for, and may exercise every right and power of, Casella
and Casella will be discharged from all obligations and covenants under this
Indenture and the Notes.

          (b)     No Guarantor may, and Casella will not cause or permit any
Guarantor to, consolidate with or merge with or into (whether or not such
Guarantor is the surviving Person), another Person unless:

          (1)     immediately after such transaction, no Default exists

     Liens incurred, assumed or granted in connection with or in respect of such
     transaction); and

          (2)     the Person formed by or surviving any such consolidation or
     merger (if other than such Guarantor) assumes all the obligations of such
     Guarantor under its Subsidiary Guarantee, this Indenture and the Exchange
     and Registration Rights Agreement pursuant to agreements reasonably
     satisfactory to the Trustee.

The requirements of this clause (b) shall not apply to (x) a consolidation or
merger of any Guarantor with or into Casella or any other Guarantor so long as
Casella or a Guarantor survives such consolidation or merger or (y) the sale by
consolidation or merger of a Guarantor, which sale is covered by and complies
with Section 4.13.

          (c)     Casella will deliver to the Trustee prior to the consummation
of each proposed transaction an Officers' Certificate certifying that the
conditions set forth above are satisfied and an Opinion of Counsel, which

     date of this Indenture, if that default:

                  (a)  is caused by a failure to pay principal of or premium, if
          any, or interest on such Indebtedness prior to the expiration of the
          grace period provided in such Indebtedness on the date of such default

     Guarantee of any Significant Subsidiary shall be held in any judicial
     proceeding to be unenforceable or invalid or shall cease for any reason to
     be in full force and effect or any Guarantor, or any Person acting on

                  (f)  admits in writing its inability to pay its debts
          generally as they become due.

SECTION 6.02.  ACCELERATION.

          In the case of an Event of Default arising from either Section 6.01(8)
or (9) with respect to Casella or any Significant Subsidiary, all outstanding
Notes will become due and payable immediately without further action or notice.
If any other Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately.

          At any time after a declaration of acceleration with respect to the
Notes as described in the preceding paragraph, the Holders of a majority in
principal amount of the Notes may rescind and cancel such declaration and its
consequences:

          (1)     if the rescission would not conflict with any judgment or
     decree;

          (2)     if all existing Defaults have been cured or waived except
     nonpayment of principal or interest that has become due solely because of
     the acceleration;

          (3)     to the extent the payment of such interest is lawful, interest
     on overdue installments of interest and overdue principal, which has become
     due otherwise than by such declaration of acceleration, has been paid;

          (4)     if Casella has paid the Trustee its reasonable compensation
     and reimbursed the Trustee for its expenses, disbursements and advances;
     and

          (5)     in the event of the cure or waiver of a Default of the type
     set forth in Section 6.01(8) or (9), the Trustee shall have received an
     Officers' Certificate and an Opinion of Counsel that such Default has been
     cured or waived.

No such rescission shall affect any subsequent Default or impair any right
consequent thereto.

<Page>

                                      -75-

SECTION 6.03.  OTHER REMEDIES.

          If a Default occurs and is continuing, the Trustee may pursue any
available remedy by proceeding at law or in equity to collect the payment of
principal of or interest on the Notes or to enforce the performance of any
provision of the Notes or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Noteholder in exercising any right or remedy
accruing upon a Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Default. No remedy is exclusive of any other
remedy. All available remedies are cumulative to the extent permitted by law.

SECTION 6.04.  WAIVER OF PAST DEFAULTS.

          Subject to Sections 2.09, 6.07 and 9.02, the Holders of a majority in
principal amount of the outstanding Notes by notice to the Trustee may waive an
existing Default and its consequences, except a Default in the payment of
principal of or interest on any Note as specified in Section 6.01(1) or (2).
Casella shall deliver to the Trustee an Officers' Certificate stating that the
requisite percentage of Holders have consented to such waiver and attaching
copies of such consents. When a Default is waived, it is cured and ceases.

SECTION 6.05.  CONTROL BY MAJORITY.

          The Holders of not less than a majority in principal amount of the
outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on it. Subject to Section 7.01, however, the Trustee may refuse
to follow any direction that conflicts with any law or this Indenture, that the
Trustee determines may be unduly prejudicial to the rights of another
Noteholder, or that may involve the Trustee in personal liability; PROVIDED that
the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

          In the event the Trustee takes any action or follows any direction
pursuant to this Indenture, the Trustee shall be entitled to indemnification
against any loss or expense caused by taking such action or following such
direction.

SECTION 6.06.  LIMITATION ON SUITS.

          A Noteholder may not pursue any remedy with respect to this Indenture
or the Notes unless:

<Page>

                                      -76-

          (1)     the Holder gives to the Trustee written notice of a continuing
     Event of Default;

          (2)     the Holder or Holders of at least 25% in principal amount of
     the outstanding Notes make a written request to the Trustee to pursue the
     remedy;

          (3)     such Holder or Holders offer and provide to the Trustee
     indemnity satisfactory to the Trustee against any loss, liability or
     expense;

          (4)     the Trustee does not comply with the request within 45 days
     after receipt of the request and the offer and the provision of indemnity;
     and

          (5)     during such 45-day period the Holder or Holders of a majority
     in principal amount of the outstanding Notes do not give the Trustee a
     direction which, in the opinion of the Trustee, is inconsistent with the
     request.

          A Noteholder may not use this Indenture to prejudice the rights of
another Noteholder or to obtain a preference or priority over such other
Noteholder.

SECTION 6.07.  RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

          Notwithstanding any other provision of this Indenture, the right of
any Holder to receive payment of principal of and interest on a Note, on or
after the respective due dates expressed in such Note, or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of the Holder.

SECTION 6.08.  COLLECTION SUIT BY TRUSTEE.

          If a Default in payment of principal or interest specified in Section
6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its
own name and as trustee of an express trust against Casella or any other obligor
on the Notes for the whole amount of principal and accrued interest and fees
remaining unpaid, together with interest on overdue principal and, to the extent
that payment of such interest is lawful, interest on overdue installments of
interest, in each case at the rate PER ANNUM borne by the Notes and such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

SECTION 6.09.  TRUSTEE MAY FILE PROOFS OF CLAIM.

          The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim

<Page>

                                      -77-

for the compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel) and the Noteholders allowed in any judicial proceedings
relating to Casella, its creditors or its property and shall be entitled and
empowered to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same, and any Custodian in
any such judicial proceedings is hereby authorized by each Noteholder to make
such payments to the Trustee and, in the event that the Trustee shall consent to
the making of such payments directly to the Noteholders, to pay to the Trustee
any amount due to it for the compensation, expenses, disbursements and advances
of the Trustee, its agent and counsel, and any other amounts due the Trustee
under Section 7.07. Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any
Noteholder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Noteholder in any such
proceeding. The Trustee shall be entitled to participate as a member of any
official committee of creditors in the matters as it deems necessary or
advisable.

SECTION 6.10.  PRIORITIES.

          If the Trustee collects any money or property pursuant to this Article
Six, it shall pay out the money or property in the following order:

          First: to the Trustee for amounts due under Section 7.07;

          Second: to Holders for interest accrued on the Notes, ratably, without
     preference or priority of any kind, according to the amounts due and
     payable on the Notes for interest;

          Third: to Holders for principal amounts due and unpaid on the Notes,
     ratably, without preference or priority of any kind, according to the
     amounts due and payable on the Notes for principal; and

          Fourth: to Casella or, if applicable, the Guarantors, as their
     respective interests may appear.

          The Trustee, upon prior notice to Casella, may fix a record date and
payment date for any payment to Noteholders pursuant to this Section 6.10.

SECTION 6.11.  UNDERTAKING FOR COSTS.

          In any suit for the enforcement of any right or remedy under this

litigant in the suit of an undertaking to pay the

<Page>

                                      -78-

costs of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys' fees and expenses, against any party litigant in
the suit, having due regard to the merits and good faith of the claims or
defenses made by the party litigant. This Section 6.11 does not apply to a suit
by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by a
Holder or Holders of more than 10% in principal amount of the outstanding Notes.

                                  ARTICLE SEVEN

                                     TRUSTEE

SECTION 7.01.  DUTIES OF TRUSTEE.

          (a)     If a Default has occurred and is continuing, the Trustee shall
exercise such of the rights and powers vested in it by this Indenture and use
the same degree of care and skill in their exercise as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

          (b)     Except during the continuance of a Default:

          (1)     The Trustee need perform only those duties as are specifically
     set forth herein or in the TIA and no duties, covenants, responsibilities
     or obligations shall be implied in this Indenture against the Trustee.

          (2)     In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates (including Officers'
     Certificates) or opinions (including Opinions of Counsel) furnished to the
     Trustee and conforming to the requirements of this Indenture. However, in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     examine the certificates and opinions to determine whether or not they
     conform to the requirements of this Indenture.

          (c)     Notwithstanding anything to the contrary herein, the Trustee
may not be relieved from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:

          (1)     This paragraph does not limit the effect of paragraph (b) of
     this Section 7.01.

<Page>

                                      -79-

          (2)     The Trustee shall not be liable for any error of judgment made
     in good faith by a Responsible Officer, unless it is proved that the
     Trustee was negligent in ascertaining the pertinent facts.

          (3)     The Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05.

          (d)     No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or to take or omit to take any action
under this Indenture or take any action at the request or direction of Holders
if it shall have reasonable grounds for believing that repayment of such funds
is not assured to it.

          (e)     Whether or not therein expressly so provided, every provision
of this Indenture that in any way relates to the Trustee is subject to this
Section 7.01.

          (f)     The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with Casella. Money
held in trust by the Trustee need not be segregated from other funds except to
the extent required by law.

          (g)     In the absence of bad faith, negligence or willful misconduct
on the part of the Trustee, the Trustee shall not be responsible for the
application of any money by any Paying Agent other than the Trustee.

SECTION 7.02.  RIGHTS OF TRUSTEE.

          Subject to Section 7.01:

          (a)     The Trustee may rely conclusively on any document believed by
     it to be genuine and to have been signed or presented by the proper Person.
     The Trustee need not investigate any fact or matter stated in the document.

          (b)     Before the Trustee acts or refrains from acting, it may
     require an Officers' Certificate and an Opinion of Counsel, which shall
     conform to the provisions of Section 12.05. The Trustee shall not be liable
     for any action it takes or omits to take in good faith in reliance on such
     certificate or opinion.

          (c)     The Trustee may act through its attorneys and agents and shall
     not be responsible for the misconduct or negligence of any agent (other
     than an agent who is an employee of the Trustee) appointed with due care.

<Page>

                                      -80-

          (d)     The Trustee shall not be liable for any action it takes or
     omits to take in good faith which it reasonably believes to be authorized
     or within its rights or powers.

          (e)     The Trustee may consult with counsel of its selection and the
     advice or opinion of such counsel as to matters of law shall be full and
     complete authorization and protection from liability in respect of any
     action taken, omitted or suffered by it hereunder in good faith and in
     accordance with the advice or opinion of such counsel.

          (f)     The Trustee shall be under no obligation to exercise any of
     the rights or powers vested in it by this Indenture at the request, order
     or direction of any of the Holders pursuant to the provisions of this
     Indenture, unless such Holders shall have offered to the Trustee reasonable
     security or indemnity satisfactory to it against the costs, expenses and
     liabilities which may be incurred therein or thereby.

          (g)     The Trustee shall not be bound to make any investigation into
     the facts or matters stated in any resolution, certificate (including any
     Officers' Certificate), statement, instrument, opinion (including any
     Opinion of Counsel), notice, request, direction, consent, order, bond,
     debenture, or other paper or document, but the Trustee, in its discretion,
     may make such further inquiry or investigation into such facts or matters
     as it may see fit and, if the Trustee shall determine to make such further
     inquiry or investigation, it shall be entitled, upon reasonable notice to
     Casella, to examine the books, records, and premises of Casella, personally
     or by agent or attorney at the sole cost of Casella.

          (h)     The Trustee shall not be required to give any bond or surety
     in respect of the performance of its powers and duties hereunder.

          (i)     The permissive rights of the Trustee to do things enumerated
     in this Indenture shall not be construed as duties.

          (j)     The Trustee shall not be deemed to have notice of any Default
     unless a Responsible Officer of the Trustee has actual knowledge thereof or
     unless written notice of any event which is in fact such a default is
     received by the Trustee at the Corporate Trust Office of the Trustee, and
     such notice references the Notes and this Indenture.

          (k)     The rights, privileges, protections, immunities and benefits
     given to the Trustee, including, without limitation, its right to be
     indemnified, are extended to, and shall be enforceable by, the Trustee in
     each of its capacities hereunder, and to each agent, custodian and other
     Person employed to act hereunder.

                                      -81-

SECTION 7.03.  INDIVIDUAL RIGHTS OF TRUSTEE.

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with Casella, its Subsidiaries
or their respective Affiliates with the same rights it would have if it were not
Trustee. Any Agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11.

SECTION 7.04.  TRUSTEE'S DISCLAIMER.

          The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for Casella's use of the proceeds from the Notes, and it shall not
be responsible for any statement of Casella in this Indenture or any document
issued in connection with the sale of Notes or any statement in the Notes other
than the Trustee's certificate of authentication. The Trustee makes no
representations with respect to the effectiveness or adequacy of this Indenture.

SECTION 7.05.  NOTICE OF DEFAULT.

          If a Default occurs and is continuing and the Trustee receives actual
notice of such Default, the Trustee shall mail to each Noteholder notice of the
uncured Default within 60 days after such Default occurs. Except in the case of
a Default in payment of principal of, or interest on, any Note, including an
accelerated payment and the failure to make payment on the Change of Control
Payment Date pursuant to a Change of Control Offer or the Asset Sale Offer
Payment Date pursuant to an Asset Sale Offer, the Trustee may withhold the
notice if and so long as the Board of Directors, the executive committee, or a
trust committee of directors and/or Responsible Officers, of the Trustee in good
faith determines that withholding the notice is in the interest of the
Noteholders.

SECTION 7.06.  REPORTS BY TRUSTEE TO HOLDERS.

          Within 60 days after each November 15, beginning with November 15,
2003, the Trustee shall, to the extent that any of the events described in TIA
Section 313(a) occurred within the previous twelve months, but not otherwise,
mail to each Noteholder a brief report dated as of such date that complies with
TIA Section 313(a). The Trustee also shall comply with TIA Sections 313(b),
313(c) and 313(d).

          A copy of each report at the time of its mailing to Noteholders shall
be mailed to Casella and filed with the Commission and each securities exchange,
if any, on which the Notes are listed.

          Casella shall notify the Trustee if the Notes become listed on any
securities exchange or of any delisting thereof and the Trustee shall comply
with TIA Section 313(d).

                                      -82-

SECTION 7.07.  COMPENSATION AND INDEMNITY.

          Casella shall pay to the Trustee from time to time such compensation
as Casella and the Trustee shall from time to time agree in writing for its
services hereunder. The Trustee's compensation shall not be limited by any law
on compensation of a trustee of an express trust. Casella shall reimburse the
Trustee upon request for all reasonable disbursements, expenses and advances
(including reasonable fees and expenses of counsel) incurred or made by it in
addition to the compensation for its services, except any such disbursements,
expenses and advances as may be attributable to the Trustee's negligence, bad
faith or willful misconduct. Such expenses shall include the reasonable fees and
expenses of the Trustee's agents and counsel.

          Casella shall indemnify each of the Trustee or any predecessor Trustee
and its agents, employees, officers, stockholders and directors for, and hold
them harmless against, any and all loss, damage, claims including taxes (other
than taxes based upon, measured by or determined by the income of the Trustee),
liability or expense incurred by them except for such actions to the extent
caused by any negligence, bad faith or willful misconduct on their part, arising
out of or in connection with the acceptance or administration of this trust
including the reasonable costs and expenses of defending themselves against or
investigating any claim or liability in connection with the exercise or
performance of any of the Trustee's rights, powers or duties hereunder. The
Trustee shall notify Casella promptly of any claim asserted against the Trustee
or any of its agents, employees, officers, stockholders and directors for which
it may seek indemnity. Casella may, subject to the approval of the Trustee
(which approval shall not be unreasonably withheld), defend the claim and the
Trustee shall cooperate in the defense. The Trustee and its agents, employees,
officers, stockholders and directors subject to the claim may have separate
counsel and Casella shall pay the reasonable fees and expenses of such counsel;
PROVIDED, HOWEVER, that Casella will not be required to pay such fees and
expenses if, subject to the approval of the Trustee (which approval shall not be
unreasonably withheld), it assumes the Trustee's defense and there is no
conflict of interest between Casella and the Trustee and its agents, employees,
officers, stockholders and directors subject to the claim in connection with
such defense as reasonably determined by the Trustee. Casella need not pay for
any settlement made without its written consent. Casella need not reimburse any
expense or indemnify against any loss or liability to the extent incurred by the
Trustee through its negligence, bad faith or willful misconduct.

          To secure Casella's payment obligations in this Section 7.07, the
Trustee shall have a senior claim prior to the Notes against all money or
property held or collected by the Trustee, in its capacity as Trustee. The
obligations of Casella and the Guarantors under this Section shall not be
subordinated to the payment of Senior Debt pursuant to Article Ten or Section
11.02 except assets or money held in trust to pay principal of or interest on
particular Notes.

<Page>

                                      -83-

          When the Trustee incurs expenses or renders services after a Default
specified in Section 6.01(8) or (9) occurs, such expenses and the compensation
for such services shall be paid to the extent allowed under any Bankruptcy Law.

          Notwithstanding any other provision in this Indenture, the foregoing
provisions of this Section 7.07 shall survive the satisfaction and discharge of
this Indenture or the appointment of a successor Trustee.

SECTION 7.08.  REPLACEMENT OF TRUSTEE.

          The Trustee may resign at any time by so notifying Casella in writing.
The Holders of a majority in principal amount of the outstanding Notes may
remove the Trustee by so notifying Casella and the Trustee and may appoint a
successor Trustee. Casella may remove the Trustee if:

          (1)     the Trustee fails to comply with Section 7.10;

          (2)     the Trustee is adjudged a bankrupt or an insolvent;

          (3)     a receiver or other public officer takes charge of the Trustee
     or its property; or

          (4)     the Trustee becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, Casella shall notify each Holder of such event
and shall promptly appoint a successor Trustee. Within one year after the
successor Trustee takes office, the Holders of a majority in principal amount of
the Notes may appoint a successor Trustee to replace the successor Trustee
appointed by Casella.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to Casella. Immediately after that, the
retiring Trustee shall transfer, after payment of all sums then owing to the
Trustee pursuant to Section 7.07, all property held by it as Trustee to the
successor Trustee, subject to the Lien provided in Section 7.07, the resignation
or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. A successor Trustee shall mail notice of its succession to each
Noteholder.

          If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, Casella or the
Holders of at least 10% in principal amount of the outstanding Notes may
petition any court of competent jurisdiction for the appointment of a successor
Trustee at the expense of Casella.

<Page>

                                      -84-

          If the Trustee fails to comply with Section 7.10, any Noteholder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

          Notwithstanding replacement of the Trustee pursuant to this Section
7.08, Casella's obligations under Section 7.07 shall continue for the benefit of
the retiring Trustee.

SECTION 7.09.  SUCCESSOR TRUSTEE BY MERGER, ETC.

          If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee; PROVIDED that such
corporation shall be otherwise qualified and eligible under this Article Seven.

SECTION 7.10.  ELIGIBILITY; DISQUALIFICATION.

          This Indenture shall always have a Trustee who satisfies the
requirement of TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee
shall have a combined capital and surplus of at least $150,000,000 as set forth
in its most recent published annual report of condition. In addition, if the
Trustee is a corporation included in a bank holding company system, the Trustee,
independently of the bank holding company, shall meet the capital requirements
of TIA Section 310(a)(2). The Trustee shall comply with TIA Section 310(b);
PROVIDED, HOWEVER, that there shall be excluded from the operation of TIA
Section 310(b)(1) any indenture or indentures under which other securities, or
certificates of interest or participation in other securities, of Casella are
outstanding, if the requirements for such exclusion set forth in TIA Section
310(b)(1) are met. The provisions of TIA Section 310 shall apply to Casella and
any other obligor of the Notes.

SECTION 7.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST CASELLA.

          The Trustee, in its capacity as Trustee hereunder, shall comply with
TIA Section 311(a), excluding any creditor relationship listed in TIA
Section 311(b). A Trustee who has resigned or been removed shall be subject to
TIA Section 311(a) to the extent indicated.

                       DISCHARGE OF INDENTURE; DEFEASANCE

SECTION 8.01.  TERMINATION OF CASELLA'S OBLIGATIONS.

          Casella may terminate its obligations under the Notes and this
Indenture, except those obligations referred to in the penultimate paragraph of
this Section 8.01, if all Notes previously authenticated and delivered (other
than destroyed, lost or stolen Notes which have been replaced or paid) have been
delivered to the Trustee for cancellation and Casella has paid all sums payable
by it hereunder, or if:

          (a)     either (i) pursuant to Article Three, Casella shall have given
     notice to the Trustee and mailed a notice of redemption to each Holder of
     the redemption of all of the Notes in accordance with the provisions hereof
     or (ii) all Notes have otherwise become or will become due and payable
     within one (1) year hereunder;

          (b)     Casella shall have irrevocably deposited or caused to be
     deposited with the Trustee or a trustee satisfactory to the Trustee, under
     the terms of an irrevocable trust agreement in form and substance
     satisfactory to the Trustee, as trust funds in trust solely for the benefit
     of the Holders of that purpose, U.S. Legal Tender or U.S. Government
     Obligations, or a combination thereof, in such amount as is, in the opinion
     of a nationally recognized firm of independent public accountants,
     sufficient without consideration of reinvestment of such interest, to pay
     principal of, premium, if any, and interest on the outstanding Notes to
     maturity or redemption; PROVIDED that the Trustee shall have been
     irrevocably instructed to apply such U.S. Legal Tender or U.S. Government
     Obligations, or a combination thereof, to the payment of said principal,
     premium, if any, and interest with respect to the Notes; and PROVIDED,
     FURTHER, that from and after the time of deposit, the U.S. Legal Tender or
     U.S. Government Obligations, or combination thereof, deposited shall not be
     subject to the rights of holders of Senior Debt pursuant to the provisions
     of Article Ten;

          (c)     no Default with respect to this Indenture or the Notes shall
     have occurred and be continuing on the date of such deposit or shall occur
     as a result of such deposit (other than a Default resulting from borrowing
     of funds to be applied to such deposit) and such deposit will not result in
     a breach or violation of, or constitute a default under, this Indenture,
     the Senior Credit Facility or any other material agreement or instrument to
     which Casella or any of its Subsidiaries is a party or by which it is
     bound;

<Page>

                                      -86-

          (d)     Casella shall have paid all other sums payable by it
     hereunder; and

          (e)     Casella shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent providing for or relating to the termination of Casella's
     obligations under the Notes and this Indenture have been complied with.
     Such Opinion of Counsel shall also state that such satisfaction and
     discharge does not result in a default under the Senior Credit Facility or
     any other material agreement or instrument then known to such counsel that
     binds or affects Casella.

          Subject to the next sentence and notwithstanding the foregoing
paragraph, Casella's obligations in Sections 2.05, 2.06, 2.07, 2.08, 4.01, 4.02,
7.07, 8.05 and 8.06 shall survive until the Notes are no longer outstanding
pursuant to the last paragraph of Section 2.08. After the Notes are no longer
outstanding, Casella's obligations in Sections 7.07, 8.05 and 8.06 shall
survive.

          After such delivery or irrevocable deposit, the Trustee upon request
shall acknowledge in writing the discharge of Casella's obligations under the
Notes and this Indenture except for those surviving obligations specified above.

SECTION 8.02.  LEGAL DEFEASANCE AND COVENANT DEFEASANCE.

          (a)     Casella may, at its option by Board Resolution of the Board of
Directors of Casella, at any time, elect to have either paragraph (b) or (c)
below be applied to all outstanding Notes upon compliance with the conditions
set forth in Section 8.03.

          (b)     Upon Casella's exercise under paragraph (a) hereof of the
option applicable to this paragraph (b), Casella shall, subject to the
satisfaction of the conditions set forth in Section 8.03, be deemed to have been
discharged from its obligations with respect to all outstanding Notes on the
date the conditions set forth below are satisfied (hereinafter, "LEGAL
DEFEASANCE"). For this purpose, Legal Defeasance means that Casella shall be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes, which shall thereafter be deemed to be "outstanding" only for
the purposes of Section 8.04 hereof and the other Sections of this Indenture
referred to in (i) and (ii) below, and to have satisfied all its other
obligations under such Notes and this Indenture and the Guarantors shall be
deemed to have satisfied all of their obligations under the Subsidiary
Guarantees and this Indenture (and the Trustee, on demand of and at the expense
of Casella, shall execute proper instruments acknowledging the same), except for
the following provisions which shall survive until otherwise terminated or
discharged hereunder:

<Page>

                                      -87-

          (i)     the rights of Holders of outstanding Notes to receive, solely
     from the trust fund described in Section 8.04 hereof, and as more fully set
     forth in such Section 8.04, payments in respect of the principal of,
     premium, if any, and interest on such Notes when such payments are due;

          (ii)    Casella's obligations with respect to such Notes under Article
     Two and Section 4.02 hereof;

          (iii)   the rights, powers, trusts, duties and immunities of the
     Trustee hereunder and Casella's obligations in connection therewith; and

          (iv)    this Article Eight.

          Subject to compliance with this Article Eight, Casella may exercise
its option under this Section 8.02(b) notwithstanding the prior exercise of its
option under Section 8.02(c) hereof.

          (c)     Upon Casella's exercise under paragraph (a) hereof of the
option applicable to this paragraph (c), Casella and the Guarantors shall,
subject to the satisfaction of the conditions set forth in Section 8.03 hereof,
be released from their respective obligations under the covenants contained in
Sections 4.03 (with respect to Restricted Subsidiaries only), 4.04, 4.05, 4.07
and 4.09 through 4.22 and clause (4) of Section 5.01(a) hereof with respect to
the outstanding Notes on and after the date the conditions set forth in Section
8.03 are satisfied (hereinafter, "COVENANT DEFEASANCE"), and the Notes shall
thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"outstanding" for all other purposes hereunder (it being understood that such
Notes shall not be deemed outstanding for accounting purposes). For this
purpose, Covenant Defeasance means that, with respect to the outstanding Notes,
Casella and the Guarantors may omit to comply with and shall have no liability
in respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute an Event of Default under Section 6.01 hereof, but, except
as specified above, the remainder of this Indenture and such Notes shall be
unaffected thereby. In addition, upon Casella's exercise under paragraph (a)
hereof of the option applicable to this paragraph (c), subject to the
satisfaction of the conditions set forth in Section 8.03 hereof, clauses (3),
(5) and (6) of Section 6.01 hereof shall not constitute Events of Default.

SECTION 8.03.  CONDITIONS TO LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

          The following shall be the conditions to the application of either
Section 8.02(b) or 8.02(c) hereof to the outstanding Notes:

          In order to exercise either Legal Defeasance or Covenant Defeasance:

          (1)     Casella must irrevocably deposit with the Trustee, in trust,
     for the benefit of the Holders of the Notes, cash in U.S. Legal Tender,
     U.S. Government Obligations, or a combination thereof, in such amounts as
     will be sufficient, in the opinion of a nationally recognized firm of
     independent public accountants, to pay the principal of, premium, if any,
     and interest on the outstanding Notes on the Stated Maturity or on the
     applicable redemption date, as the case may be, and Casella must specify
     whether the Notes are being defeased to maturity or to a particular
     redemption date;

          (2)     in the case of an election under Section 8.02(b) hereof,
     Casella shall have delivered to the Trustee an Opinion of Counsel
     reasonably acceptable to the Trustee confirming that (a) Casella has
     received from, or there has been published by, the Internal Revenue Service
     a ruling or (b) since the date of this Indenture, there has been a change
     in the applicable federal income tax law, in either case to the effect
     that, and based thereon such Opinion of Counsel shall confirm that, the
     Holders of the outstanding Notes will not recognize income, gain or loss
     for federal income tax purposes as a result of such Legal Defeasance and
     will be subject to federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such Legal
     Defeasance had not occurred;

          (3)     in the case of an election under Section 8.02(c) hereof,
     Casella shall have delivered to the Trustee an Opinion of Counsel
     reasonably acceptable to the Trustee confirming that the Holders of the
     outstanding Notes will not recognize income, gain or loss for federal
     income tax purposes as a result of such Covenant Defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such Covenant Defeasance
     had not occurred;

          (4)     no Default shall have occurred and be continuing either: (a)
     on the date of such deposit (other than a Default resulting from the
     borrowing of funds to be applied to such deposit), or (b) insofar as Events
     of Default from bankruptcy or insolvency events are concerned, at any time
     in the period ending on the 91st day after the date of deposit; PROVIDED
     that such Legal Defeasance or Covenant Defeasance, as the case may be,
     shall be deemed to have occurred on the date of such deposit, subject to an
     Event of Default from bankruptcy or insolvency within such 91-day period;

<Page>

                                      -89-

          (5)     such Legal Defeasance or Covenant Defeasance will not result
     in a breach or violation of, or constitute a default under, any material
     agreement or instrument (other than this Indenture) to which Casella or any
     of its Restricted Subsidiaries is a party or by which Casella or any of its
     Restricted Subsidiaries is bound;

          (6)     Casella must deliver to the Trustee an Officers' Certificate
     stating that the deposit was not made by Casella with the intent of
     preferring the Holders of Notes over the other creditors of Casella with
     the intent of defeating, hindering, delaying or defrauding creditors of
     Casella or others; and

          (7)     Casella must deliver to the Trustee an Officers' Certificate
     and an Opinion of Counsel stating that all conditions precedent relating to
     the Legal Defeasance or the Covenant Defeasance have been complied with.

SECTION 8.04.  APPLICATION OF TRUST MONEY.

          The Trustee or Paying Agent shall hold in trust U.S. Legal Tender and
U.S. Government Obligations deposited with it pursuant to this Article Eight,
and shall apply the deposited U.S. Legal Tender and the money from U.S.
Government Obligations in accordance with this Indenture to the payment of
principal of and interest on the Notes. The Trustee shall be under no obligation
to invest said U.S. Legal Tender and U.S. Government Obligations except as it
may agree with Casella.

          Casella shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Legal Tender and U.S.
Government Obligations deposited pursuant to Section 8.03 or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes.

          Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall deliver or pay to Casella from time to time upon Casella's request
any U.S. Legal Tender and U.S. Government Obligations held by it as provided in
Section 8.03 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

SECTION 8.05.  REPAYMENT TO CASELLA.

          Subject to this Article Eight, the Trustee and the Paying Agent shall
promptly pay to Casella upon request any excess U.S. Legal Tender and U.S.
Government Obligations held by them at any time and thereupon shall be relieved
from all liability with respect to such

<Page>

                                      -90-

money. The Trustee and the Paying Agent shall pay to Casella upon request any
money held by them for the payment of principal or interest that remains
unclaimed for two years; PROVIDED that the Trustee or such Paying Agent, before
being required to make any payment, may at the expense of Casella cause to be
published once in a newspaper of general circulation in the City of New York or
mail to each Holder entitled to such money notice that such money remains
unclaimed and that after a date specified therein which shall be at least 30
days from the date of such publication or mailing any unclaimed balance of such
money then remaining will be repaid to Casella. After payment to Casella,
Holders entitled to such money must look to Casella for payment as general
creditors unless an applicable law designates another Person.

SECTION 8.06.  REINSTATEMENT.

          If the Trustee or Paying Agent is unable to apply any U.S. Legal
Tender and U.S. Government Obligations in accordance with this Article Eight by
reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, Casella's obligations under this Indenture and the Notes shall
be revived and reinstated as though no deposit had occurred pursuant to this
Article Eight until such time as the Trustee or Paying Agent is permitted to
apply all such U.S. Legal Tender and U.S. Government Obligations in accordance
with this Article Eight; PROVIDED that if Casella has made any payment of
interest on or principal of any Notes because of the reinstatement of its
obligations, Casella shall be subrogated to the rights of the Holders of such
Notes to receive such payment from the U.S. Legal Tender and U.S. Government
Obligations held by the Trustee or Paying Agent.

                                  ARTICLE NINE

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION 9.01.  WITHOUT CONSENT OF HOLDERS.

          Subject to Section 9.03, Casella, the Guarantors and the Trustee,
together, may amend or supplement this Indenture, the Notes or the Subsidiary
Guarantees without notice to or consent of any Noteholder:

          (1)     to cure any ambiguity, defect or inconsistency;

          (2)     to provide for uncertificated Notes in addition to or in place
     of certificated Notes;

<Page>

                                      -91-

          (3)     to provide for the assumption of Casella's obligations to
     Holders of Notes in the case of a merger or consolidation or sale of all or
     substantially all of Casella's assets;

          (4)     to make any change that would provide any additional rights or
     benefits to the Holders of Notes or that does not adversely affect the
     legal rights under this Indenture of any Holder; or

          (5)     to comply with requirements of the Commission in order to
     effect or maintain the qualification of this Indenture under the TIA;

PROVIDED that Casella has delivered to the Trustee an Opinion of Counsel and an
Officers' Certificate, each stating that such amendment or supplement complies
with the provisions of this Section 9.01.

SECTION 9.02.  WITH CONSENT OF HOLDERS.

          (a)     Subject to Sections 6.07 and 9.03, Casella, the Guarantors and
the Trustee, together, with the written consent of the Holder or Holders of a
majority in aggregate principal amount of the outstanding Notes, may amend or
supplement this Indenture, the Notes or the Subsidiary Guarantees, without
notice to any other Noteholders. Subject to Sections 6.07 and 9.03, the Holder
or Holders of a majority in aggregate principal amount of the outstanding Notes
may waive compliance with any provision of this Indenture, the Notes or the
Subsidiary Guarantees without notice to any other Noteholders.

          (b)     Notwithstanding Section 9.02(a), without the consent of each
Noteholder affected, an amendment, supplement or waiver, including a waiver
pursuant to Section 6.04, may not (with respect to any Notes held by a
non-consenting Holder):

          (1)     reduce the principal amount of Notes whose Holders must
     consent to an amendment, supplement or waiver;

          (2)     reduce the principal of or change or have the effect of
     changing the fixed maturity of any Note or alter the provisions with
     respect to the redemption of the Notes (other than provisions of Sections
     4.09 and 4.13);

          (3)     reduce the rate of or change the time for payment of interest
     on any Note;

          (4)     waive an uncured Default in the payment of principal of or
     premium, if any, or interest on the Notes (except a rescission of
     acceleration of the Notes by the

<Page>

                                      -92-

     Holders of a majority in aggregate principal amount of the Notes and a
     waiver of the payment default that resulted from such acceleration);

          (5)     make any Note payable in money other than that stated in the
     Notes;

          (6)     impair or affect the right of any Holder of Notes to receive
     payment of principal of and interest on the Notes on or after the due dates
     therefor or to institute suit for payment for the enforcement of any such
     payment on or after the due dates therefor, or make any changes in the
     provisions of this Indenture permitting Holders of a majority in principal
     amount of Notes to waive any past Default and its consequences;

          (7)     waive a redemption payment with respect to any Note (other
     than a payment required by one of the provisions of Section 4.09 or Section
     4.13, subject to clause (9) below);

          (8)     release any Guarantor from any of its obligations under its
     Subsidiary Guarantee or this Indenture otherwise than in accordance with
     the terms of this Indenture;

          (9)     in the event that a Change of Control has occurred or an Asset
     Sale has been consummated, amend, change or modify in any material respect
     the obligation of Casella to make and consummate a Change of Control Offer
     or make and consummate an Asset Sale Offer with respect to such Change of
     Control or Asset Sale;

          (10)    make any change to Article Ten or Section 11.02 (including the
     related definitions) that adversely affects the rights of the Holders of
     the Notes; or

          (11)    make any change in the preceding amendment and waiver
     provisions.

          (c)     It shall not be necessary for the consent of the Holders under
this Section to approve the particular form of any proposed amendment,
supplement or waiver but it shall be sufficient if such consent approves the
substance thereof.

          (d)     After an amendment, supplement or waiver under this Section
9.02 becomes effective, Casella shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
Casella to mail such notice, or any defect therein, shall not, however, in any
way impair or affect the validity of any such amendment, supplement or waiver.

                                      -93-

SECTION 9.03.  EFFECT ON SENIOR DEBT.

          No amendment of, or supplement or waiver to, this Indenture shall
adversely affect the rights of any holder of Senior Debt under Article Ten and
Section 11.02 and the defined terms as used therein without the consent of such
holder or its Representative.

SECTION 9.04.  COMPLIANCE WITH TIA.

          From the date on which this Indenture is qualified under the TIA,
every amendment, waiver or supplement of this Indenture, the Notes or the
Subsidiary Guarantees shall comply with the TIA as then in effect.

SECTION 9.05.  REVOCATION AND EFFECT OF CONSENTS.

          Until an amendment, waiver or supplement becomes effective, a consent
to it by a Holder is a continuing consent by the Holder and every subsequent
Holder of a Note or portion of a Note that evidences the same debt as the
consenting Holder's Note, even if notation of the consent is not made on any
Note. However, any such Holder or subsequent Holder may revoke the consent as to
his Note or portion of his Note by notice to the Trustee or Casella received
before the date on which the Trustee receives an Officers' Certificate
certifying that the Holders of the requisite principal amount of Notes have
consented (and not theretofore revoked such consent) to the amendment,
supplement or waiver.

          Casella may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver which record date shall be at least 30 days prior to the
first solicitation of such consent. If a record date is fixed, then
notwithstanding the last sentence of the immediately preceding paragraph, those
Persons who were Holders at such record date (or their duly designated proxies),
and only those Persons, shall be entitled to revoke any consent previously
given, whether or not such Persons continue to be Holders after such record
date. No such consent shall be valid or effective for more than 90 days after
such record date. Casella shall inform the Trustee in writing of the fixed
record date if applicable.

          After an amendment, supplement or waiver becomes effective, it shall
bind every Noteholder, unless it makes a change described in any of clauses (1)
through (11) of Section 9.02(b), in which case, the amendment, supplement or
waiver shall bind only each Holder of a Note who has consented to it and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as
the consenting Holder's Note; PROVIDED that any such waiver shall not impair or
affect the right of any Holder to receive payment of principal of and interest
on a Note, on or after the respective due dates therefor, or to bring suit for
the enforcement

<Page>

                                      -94-

of any such payment on or after such respective dates without the consent of
such Holder.

SECTION 9.06.  NOTATION ON OR EXCHANGE OF NOTES.

          If an amendment, supplement or waiver changes the terms of a Note,
Casella may require the Holder of the Note to deliver it to the Trustee. Casella
shall provide the Trustee with an appropriate notation on the Note about the
changed terms and cause the Trustee to return it to the Holder at Casella's
expense. Alternatively, if Casella or the Trustee so determines, Casella in
exchange for the Note shall issue and the Trustee shall authenticate a new Note
that reflects the changed terms. Failure to make the appropriate notation or
issue a new Note shall not affect the validity and effect of such amendment,
supplement or waiver.

SECTION 9.07.  TRUSTEE TO SIGN AMENDMENTS, ETC.

          The Trustee shall execute any amendment, supplement or waiver
authorized pursuant to this Article Nine; PROVIDED that the Trustee may, but
shall not be obligated to, execute any such amendment, supplement or waiver
which affects the Trustee's own rights, duties or immunities under this
Indenture. The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel and an Officers' Certificate
each stating that the execution of any amendment, supplement or waiver
authorized pursuant to this Article Nine is authorized or permitted by this
Indenture and constituted the legal, valid and binding obligations of Casella
enforceable in accordance with its terms. Such Opinion of Counsel shall be at
the expense of Casella.

                                   ARTICLE TEN

                             SUBORDINATION OF NOTES

SECTION 10.01. NOTES SUBORDINATED TO SENIOR DEBT.

          Anything herein to the contrary notwithstanding, Casella, for itself
and its successors, and each Holder, by his or her acceptance of Notes, agrees
that the payment of all Obligations owing to the Holders in respect of the Notes
is subordinated, to the extent and in the manner provided in this Article Ten,
to the prior payment in full in cash or cash equivalents, or such payment duly
provided for to the satisfaction of the holders of Senior Debt, of all
Obligations on Senior Debt (including the Obligations with respect to the Senior
Credit Facility, whether outstanding on the Issue Date or thereafter incurred).
Notwithstanding the foregoing, payments and distributions (A) of Permitted
Junior Securities and (B) made relating to the Notes from the trust established
pursuant to Article Eight shall not be so subordinated in right

<Page>

                                      -95-

of payment, so long as, with respect to (B), (i) the conditions specified in
Article Eight (without any waiver or modification of the requirement that the
deposits pursuant thereto do not conflict with the terms of the Senior Credit
Facility or any other Senior Debt) are satisfied on the date of any deposit
pursuant to said trust and (ii) such payments and distributions did not violate
the provisions of this Article Ten or Section 11.02 of this Indenture when made.

          This Article Ten shall constitute a continuing offer to all Persons
who become holders of, or continue to hold, Senior Debt, and such provisions are
made for the benefit of the holders of Senior Debt and such holders are made
obligees hereunder and any one or more of them may enforce such provisions.

SECTION 10.02. SUSPENSION OF PAYMENT WHEN SENIOR DEBT IS IN DEFAULT.

          (a)     If any default occurs and is continuing in the payment when
due, whether at maturity, upon any redemption, by declaration or otherwise, of
any principal of, interest on, unpaid drawings for letters of credit issued in
respect of, or fees with respect to, any Senior Debt (a "PAYMENT DEFAULT"), then
no payment or distribution of any kind or character shall be made by or on
behalf of Casella or any other Person on its or their behalf with respect to any
Obligations on or relating to the Notes or to acquire any of the Notes for cash
or assets or otherwise.

          (b)     If any other event of default (other than a Payment Default)
occurs and is continuing with respect to any Designated Senior Debt (as such
event of default is defined in the instrument creating or evidencing such
Designated Senior Debt) permitting the holders of such Designated Senior Debt
then outstanding to accelerate the maturity thereof (a "NON-PAYMENT DEFAULT")
and if the Representative for the respective issue of Designated Senior Debt
gives notice of the Non-Payment Default to the Trustee stating that such notice
is a payment blockage notice (a "PAYMENT BLOCKAGE NOTICE"), then during the
period (the "PAYMENT BLOCKAGE PERIOD") beginning upon the delivery of such
Payment Blockage Notice and ending on the earlier of the 179th day after such
delivery and the date on which (x) all events of default with respect to all
Designated Senior Debt have been cured or waived or cease to exist, (y) all
Designated Senior Debt with respect to which any such Non-Payment Default has
occurred and is continuing is discharged or paid in full in cash or cash
equivalents, or (z) the Trustee receives notice thereof from the Representative
for the respective issue of Designated Senior Debt terminating the Payment
Blockage Period, neither Casella nor any other Person on its behalf shall (x)
make any payment of any kind or character with respect to any Obligations on or
with respect to the Notes or (y) acquire any of the Notes for cash or assets or
otherwise. Notwithstanding anything herein to the contrary, (x) in no event will
a Payment Blockage Period extend beyond 179 days from the date the applicable
Payment Blockage Notice is received by the Trustee and (y) only one such Payment
Blockage Period may be commenced within any 360 consecutive days. For all
purposes of this Section 10.02(b), no Non-Payment

<Page>

                                      -96-

Default which existed or was continuing on the date of the commencement of any
Payment Blockage Period with respect to the Designated Senior Debt shall be, or
be made, the basis for the commencement of a second Payment Blockage Period by
the Representative of such Designated Senior Debt whether or not within a period
of 360 consecutive days, unless such Non-Payment Default shall have been cured
or waived for a period of not less than 90 consecutive days (it being
acknowledged that any subsequent action, or any breach of any financial
covenants for a period ending after the date of commencement of such Payment
Blockage Period that, in either case, would give rise to a Non-Payment Default
pursuant to any provisions under which a Non-Payment Default previously existed
or was continuing shall constitute a new Non-Payment Default for this purpose).

          (c)     The foregoing Sections 10.02(a) and (b) shall not apply to
payments and distributions (A) of Permitted Junior Securities and (B) made
relating to the Notes from the trust established pursuant to Article Eight, so
long as, with respect to (B), (i) the conditions specified in Article Eight
(without any waiver or modification of the requirement that the deposits
pursuant thereto do not conflict with the terms of the Senior Credit Facility or
any other Senior Debt) are satisfied on the date of any deposit pursuant to said
trust and (ii) such payments and distributions did not violate the provisions of
this Article Ten when made.

          (d)     In the event that, notwithstanding the foregoing, any payment
shall be received by the Trustee or any Holder when such payment is prohibited
by the foregoing provisions of this Section 10.02, such payment shall be held in
trust for the benefit of, and shall be paid over or delivered to, the holders of
Senior Debt (PRO RATA to such holders on the basis of the respective amount of
Senior Debt held by such holders) or their respective Representatives, as their
respective interests may appear. The Trustee shall be entitled to rely on
information regarding amounts outstanding on the Senior Debt, if any, received
from the holders of the Senior Debt (or their Representatives).

          Nothing contained in this Article Ten shall limit the right of the
Trustee or the Holders of Notes to take any action to accelerate the maturity of
the Notes pursuant to Section 6.02 or to pursue any rights or remedies
hereunder; PROVIDED that all Senior Debt thereafter due or declared to be due
shall first be paid in full in cash or cash equivalents before the Holders are
entitled to receive any payment of any kind or character with respect to
Obligations on the Notes.

SECTION 10.03. NOTES SUBORDINATED TO PRIOR PAYMENT OF ALL SENIOR DEBT ON
               DISSOLUTION, LIQUIDATION OR REORGANIZATION OF CASELLA.

          (a)     Upon any payment or distribution of assets of Casella of any
kind or character, whether in cash, assets or securities, to creditors upon any
total or partial liquidation, dissolution, winding-up, reorganization,
assignment for the benefit of creditors or marshaling

<Page>

                                      -97-

of assets and liabilities of Casella or in a bankruptcy, reorganization,
insolvency, receivership or other similar proceeding relating to Casella or its
assets, whether voluntary or involuntary, all Obligations due or to become due
upon all Senior Debt shall first be paid in full in cash or cash equivalents, or
such payment duly provided for to the satisfaction of the holders of Senior
Debt, before any payment or distribution of any kind or character is made on
account of any Obligations on or relating to the Notes, or for the acquisition
of any of the Notes for cash or assets or otherwise. Upon any such dissolution,
winding-up, liquidation, reorganization, receivership or similar proceeding, any
payment or distribution of assets of Casella of any kind or character, whether
in cash, assets or securities, to which the Holders of the Notes or the Trustee
under this Indenture would be entitled, except for the provisions hereof, shall
be paid by Casella or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other Person making such payment or distribution, or by the
Holders or by the Trustee under this Indenture if received by them, directly to
the holders of Senior Debt (PRO RATA to such holders on the basis of the
respective amounts of Senior Debt held by such holders) or their respective
Representatives, or to the trustee or trustees under any indenture pursuant to
which any of such Senior Debt may have been issued, as their respective
interests may appear, for application to the payment of Senior Debt remaining
unpaid until all such Senior Debt has been paid in full in cash or cash
equivalents after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of Senior Debt.

          (b)     To the extent any payment of Senior Debt (whether by or on
behalf of Casella, as proceeds of security or enforcement of any right of setoff
or otherwise) is declared to be fraudulent or preferential, set aside or
required to be paid to any receiver, trustee in bankruptcy, liquidating trustee,
agent or other similar Person under any bankruptcy, insolvency, receivership,
fraudulent conveyance or similar law, then, if such payment is recovered by, or
paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent
or other similar Person, the Senior Debt or part thereof originally intended to
be satisfied shall be deemed to be reinstated and outstanding as if such payment
had not occurred.

          It is further agreed that any diminution (whether pursuant to court
decree or otherwise, including without limitation for any of the reasons
described in the preceding sentence) of Casella's obligation to make any
distribution or payment pursuant to any Senior Debt, except to the extent such
diminution occurs by reason of the repayment (which has not been disgorged or
returned) of such Senior Debt in cash or cash equivalents, shall have no force
or effect for purposes of the subordination provisions contained in this Article
Ten, with any turnover of payments as otherwise calculated pursuant to this
Article Ten to be made as if no such diminution had occurred.

          (c)     In the event that, notwithstanding the foregoing, any payment
or distribution of assets of Casella of any kind or character, whether in cash,
assets or securities, shall be received by any Holder when such payment or
distribution is prohibited by this Section 10.03,

<Page>

                                      -98-

such payment or distribution shall be held in trust for the benefit of, and
shall be paid over or delivered to, the holders of Senior Debt (PRO RATA to such
holders on the basis of the respective amount of Senior Debt held by such
holders) or their respective Representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Debt may have been
issued, as their respective interests may appear, for application to the payment
of Senior Debt remaining unpaid until all such Senior Debt has been paid in full
in cash or cash equivalents, after giving effect to any concurrent payment,
distribution or provision therefor to or for the holders of such Senior Debt.

          (d)     The consolidation of Casella with, or the merger of Casella
with or into, another Person or the liquidation or dissolution of Casella
following the conveyance or transfer of all or substantially all of its assets,
to another Person upon the terms and conditions provided in Article Five hereof
and as long as permitted under the terms of the Senior Debt shall not be deemed
a dissolution, winding-up, liquidation or reorganization for the purposes of
this Section if such other Person shall, as a part of such consolidation,
merger, conveyance or transfer, assume Casella's obligations hereunder in
accordance with Article Five hereof.

SECTION 10.04. PAYMENTS MAY BE MADE PRIOR TO DISSOLUTION.

          Nothing contained in this Article Ten or elsewhere in this Indenture
shall prevent (i) Casella, except under the conditions described in Sections
10.02 and 10.03, from making payments at any time for the purpose of making
payments of principal of and interest on the Notes, or from depositing with the
Trustee any moneys for such payments, or (ii) in the absence of actual knowledge
by the Trustee that a given payment would be prohibited by Section 10.02 or
10.03, the application by the Trustee of any moneys deposited with it for the
purpose of making such payments of principal of, and interest on, the Notes to
the Holders entitled thereto unless at least two Business Days prior to the date
upon which such payment would otherwise become due and payable a Responsible
Officer of the Trustee shall have actually received the written notice provided
for in the first sentence of Section 10.02(b) or in Section 10.07 (PROVIDED
that, notwithstanding the foregoing, the Holders receiving any payments made in
contravention of Section 10.02 and/or 10.03 (and the respective such payments)
shall otherwise be subject to the provisions of Section 10.02 and Section
10.03). Casella shall give prompt written notice to the Trustee of any
dissolution, winding-up, liquidation or reorganization of Casella, although any
delay or failure to give any such notice shall have no effect on the
subordination provisions contained herein.

SECTION 10.05. HOLDERS TO BE SUBROGATED TO RIGHTS OF HOLDERS OF SENIOR DEBT.

          Subject to the payment in full in cash or cash equivalents of all
Senior Debt, the Holders of the Notes shall be subrogated to the rights of the
holders of Senior Debt to receive

<Page>

                                      -99-

payments or distributions of cash, assets or securities of Casella applicable to
the Senior Debt until the Notes shall be paid in full; and, for the purposes of
such subrogation, no such payments or distributions to the holders of the Senior
Debt by or on behalf of Casella, or by or on behalf of the Holders by virtue of
this Article Ten, which otherwise would have been made to the Holders shall, as
between Casella and the Holders, be deemed to be a payment by Casella to or on
account of the Senior Debt, it being understood that the provisions of this
Article Ten are and are intended solely for the purpose of defining the relative
rights of the Holders, on the one hand, and the holders of Senior Debt, on the
other hand.

SECTION 10.06. OBLIGATIONS OF CASELLA UNCONDITIONAL.

          Nothing contained in this Article Ten or elsewhere in this Indenture
or in the Notes is intended to or shall impair, as among Casella, its creditors
other than the holders of Senior Debt, and the Holders, the obligation of
Casella, which is absolute and unconditional, to pay to the Holders the
principal of and any interest on the Notes as and when the same shall become due
and payable in accordance with their terms, or is intended to or shall affect
the relative rights of the Holders and creditors of Casella other than the
holders of the Senior Debt, nor shall anything herein or therein prevent the
Holder of any Note or the Trustee on its behalf from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture, subject
to the rights, if any, in respect of cash, assets or securities of Casella
received upon the exercise of any such remedy.

SECTION 10.07. NOTICE TO TRUSTEE.

          Casella shall give prompt written notice to the Trustee of any fact
known to Casella which would prohibit the making of any payment to or by the
Trustee in respect of the Notes pursuant to the provisions of this Article Ten,
although any delay or failure to give any such notice shall have no effect on
the subordination provisions contained herein. Regardless of anything to the
contrary contained in this Article Ten or elsewhere in this Indenture, the
Trustee shall not be charged with knowledge of the existence of any default or
event of default with respect to any Senior Debt or of any other facts which
would prohibit the making of any payment to or by the Trustee unless and until
the Trustee shall have received notice in writing from Casella, or from a holder
of Senior Debt or a Representative therefor and, prior to the receipt of any
such written notice, the Trustee shall be entitled to assume (in the absence of
actual knowledge to the contrary) that no such facts exist. The Trustee shall be
entitled to rely on the delivery to it of any notice pursuant to this Section
10.07 to establish that such notice has been given by a holder of Senior Debt
(or a trustee thereof).

          In the event that the Trustee determines in good faith that any
evidence is required with respect to the right of any Person as a holder of
Senior Debt to participate in any payment or distribution pursuant to this
Article Ten, the Trustee may request such Person to

<Page>

                                      -100-

furnish evidence to the satisfaction of the Trustee as to the amounts of Senior
Debt held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such Person under this Article Ten, and if such evidence is not
furnished the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

SECTION 10.08. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING AGENT.

          Upon any payment or distribution of assets of Casella referred to in
this Article Ten, the Trustee, subject to the provisions of Article Seven
hereof, and the Holders of the Notes shall be entitled to rely upon any order or
decree made by any court of competent jurisdiction in which any insolvency,
bankruptcy, receivership, dissolution, winding-up, liquidation, reorganization
or similar case or proceeding is pending, or upon a certificate of the receiver,
trustee in bankruptcy, liquidating trustee, assignee for the benefit of
creditors, agent or other person making such payment or distribution, delivered
to the Trustee or the Holders of the Notes, for the purpose of ascertaining the
persons entitled to participate in such payment or distribution, the holders of
the Senior Debt and other Indebtedness of Casella, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article Ten.

SECTION 10.09. TRUSTEE'S RELATION TO SENIOR DEBT.

          The Trustee and any agent of Casella or the Trustee shall be entitled
to all the rights set forth in this Article Ten with respect to any Senior Debt
which may at any time be held by it in its individual or any other capacity to
the same extent as any other holder of Senior Debt and nothing in this Indenture
shall deprive the Trustee or any such agent of any of its rights as such holder.

          With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article Ten, and no implied covenants or
obligations with respect to the holders of Senior Debt shall be read into this
Indenture against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Debt.

          Whenever a distribution is to be made or a notice given to holders or
owners of Senior Debt, the distribution may be made and the notice may be given
to their Representative, if any.

                                      -101-

SECTION 10.10. SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR OMISSIONS OF CASELLA
               OR HOLDERS OF SENIOR DEBT.

          No right of any present or future holders of any Senior Debt to
enforce subordination as provided herein shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of Casella or by
any act or failure to act, in good faith, by any such holder, or by any
noncompliance by Casella with the terms of this Indenture, regardless of any
knowledge thereof which any such holder may have or otherwise be charged with.

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee, without incurring responsibility to the
Trustee or the Holders of the Notes and without impairing or releasing the
subordination provided in this Article Ten or the obligations hereunder of the
Holders of the Notes to the holders of the Senior Debt, do any one or more of
the following: (i) change the manner, place or terms of payment or extend the
time of payment of, or renew or alter, Senior Debt, or otherwise amend or
supplement in any manner Senior Debt, or any instrument evidencing the same or
any agreement under which Senior Debt is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Debt; (iii) release any Person liable in any manner for the
payment or collection of Senior Debt; and (iv) exercise or refrain from
exercising any rights against Casella and any other Person.

SECTION 10.11. NOTEHOLDERS AUTHORIZE TRUSTEE TO EFFECTUATE SUBORDINATION OF
               NOTES.

          Each Holder of Notes by its acceptance of them authorizes and
expressly directs the Trustee on its behalf to take such action as may be
necessary or appropriate to effectuate, as between the holders of Senior Debt
and the Holders of Notes, the subordination provided in this Article Ten, and
appoints the Trustee its attorney-in-fact for such purposes, including, in the
event of any dissolution, winding-up, liquidation or reorganization of Casella
(whether in bankruptcy, insolvency, receivership, reorganization or similar
proceedings or upon an assignment for the benefit of credits or otherwise)
tending towards liquidation of the business and assets of Casella, the filing of
a claim for the unpaid balance of its Notes and accrued interest in the form
required in those proceedings.

          If the Trustee does not file a proper claim or proof of debt in the
form required in such proceeding prior to 30 days before the expiration of the
time to file such claim or claims, then the holders of the Senior Debt or their
Representative are or is hereby authorized to have the right to file and are or
is hereby authorized to file an appropriate claim for and on behalf of the
Holders of said Notes. Nothing herein contained shall be deemed to authorize the
Trustee or the holders of Senior Debt or their Representative to authorize or
consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment

<Page>

                                      -102-

or composition affecting the Notes or the rights of any Holder thereof, or to
authorize the Trustee or the holders of Senior Debt or their Representative to
vote in respect of the claim of any Holder in any such proceeding.

SECTION 10.12. THIS ARTICLE TEN NOT TO PREVENT EVENTS OF DEFAULT.

          The failure to make a payment on account of principal of or interest
on the Notes by reason of any provision of this Article Ten will not be
construed as preventing the occurrence of an Event of Default.

SECTION 10.13. TRUSTEE'S COMPENSATION NOT PREJUDICED.

          Nothing in this Article Ten will apply to amounts due to the Trustee
(other than payments of Obligations owing to Holders in respect of Notes)
pursuant to other sections of this Indenture.

                                 ARTICLE ELEVEN

                              SUBSIDIARY GUARANTEE

SECTION 11.01. UNCONDITIONAL GUARANTEE.

          Subject to the provisions of this Article Eleven, each of the
Guarantors hereby, jointly and severally, unconditionally and irrevocably
guarantees, on a senior subordinated basis to each Holder of a Note
authenticated and delivered by the Trustee and to the Trustee and its successors
and assigns, irrespective of the validity and enforceability of this Indenture,
the Notes or the obligations of Casella or any other Guarantors to the Holders
or the Trustee hereunder or thereunder: (a) (x) the due and punctual payment of
the principal of, premium, if any, and interest on the Notes when and as the
same shall become due and payable, whether at maturity, upon redemption or
repurchase, by acceleration or otherwise, (y) the due and punctual payment of
interest on the overdue principal and (to the extent permitted by law) interest,
if any, on the Notes and (z) the due and punctual payment and performance of all
other obligations of Casella and all other obligations of the other Guarantors
(including under the Subsidiary Guarantees), in each case, to the Holders or the
Trustee hereunder or thereunder (including amounts due the Trustee under Section
7.07 hereof), all in accordance with the terms hereof and thereof (collectively,
the "GUARANTEE OBLIGATIONS"); and (b) in case of any extension of time of
payment or renewal of any Notes or any of such other obligations, the due and
punctual payment and performance of Guarantee Obligations in accordance with the
terms of the extension or renewal, whether at maturity, upon redemption or
repurchase, by acceleration or otherwise. Failing payment when due of any amount
so guaranteed, or failing performance of

<Page>

                                      -103-

any other obligation of Casella to the Holders under this Indenture or under the
Notes, for whatever reason, each Guarantor shall be obligated to pay, or to
perform or cause the performance of, the same immediately. A Default under this
Indenture or the Notes shall constitute an event of default under the Subsidiary
Guarantees, and shall entitle the Holders of Notes to accelerate the obligations
of the Guarantors thereunder in the same manner and to the same extent as the
obligations of Casella.

          Each of the Guarantors hereby agrees that its obligations hereunder
shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Notes with respect
to any provisions hereof or thereof, any release of any other Guarantor, the
recovery of any judgment against Casella, any action to enforce the same,
whether or not a Subsidiary Guarantee is affixed to any particular Note, or any
other circumstance which might otherwise constitute a legal or equitable
discharge or defense of a Guarantor. Each of the Guarantors hereby waives the
benefit of diligence, presentment, demand of payment, filing of claims with a
court in the event of insolvency or bankruptcy of Casella, any right to require
a proceeding first against Casella, protest, notice and all demands whatsoever
and covenants that its Subsidiary Guarantee shall not be discharged except by
complete performance of the obligations contained in the Notes, this Indenture
and this Subsidiary Guarantee. This Subsidiary Guarantee is a guarantee of
payment and not of collection. If any Holder or the Trustee is required by any
court or otherwise to return to Casella or to any Guarantor, or any custodian,
trustee, liquidator or other similar official acting in relation to Casella or
such Guarantor, any amount paid by Casella or such Guarantor to the Trustee or
such Holder, this Subsidiary Guarantee, to the extent theretofore discharged,
shall be reinstated in full force and effect. Each Guarantor further agrees
that, as between it, on the one hand, and the Holders of Notes and the Trustee,
on the other hand, (a) subject to this Article Eleven, the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Six for
the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (b) in the event of any acceleration of such obligations
as provided in Article Six hereof, such obligations (whether or not due and
payable) shall forthwith become due and payable by the Guarantors for the
purpose of this Subsidiary Guarantee.

SECTION 11.02. SUBORDINATION OF SUBSIDIARY GUARANTEE.

          The obligations of each Guarantor under its Subsidiary Guarantee
pursuant to this Article Eleven shall be junior and subordinated to the prior
payment in full in cash or Cash Equivalents of the Senior Debt of such Guarantor
on the same basis as the Notes are junior and subordinated to Senior Debt of
Casella. For the purposes of the foregoing sentence, the Trustee and the Holders
shall have the right to receive and/or retain payments by any of

<Page>

                                      -104-

the Guarantors only at such times as they may receive and/or retain payments in
respect of the Notes pursuant to this Indenture, including Article Ten hereof.

SECTION 11.03. LIMITATION ON GUARANTOR LIABILITY.

          Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Subsidiary
Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance
for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar federal or state law to the
extent applicable to any Subsidiary Guarantee. To effectuate the foregoing
intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree
that the obligations of such Guarantor under its Subsidiary Guarantee and this
Article Eleven shall be limited to the maximum amount as will, after giving
effect to such maximum amount and all other contingent and fixed liabilities of
such Guarantor that are relevant under such laws, and after giving effect to any
collections from, rights to receive contribution from or payments made by or on
behalf of any other Guarantor in respect of the obligations of such other
Guarantor under this Article Eleven, result in the obligations of such Guarantor
under its Subsidiary Guarantee not constituting a fraudulent transfer or
conveyance.

SECTION 11.04. EXECUTION AND DELIVERY OF SUBSIDIARY GUARANTEE.

          To further evidence its Subsidiary Guarantee set forth in
Section 11.01, each Guarantor hereby agrees that a notation of such Subsidiary
Guarantee, substantially in the form of EXHIBIT E hereto, shall be endorsed on
each Note authenticated and delivered by the Trustee. Such Subsidiary Guarantee
shall be executed on behalf of each Guarantor by either manual or facsimile
signature of one Officer or other person duly authorized by all necessary
corporate action of each Guarantor who shall have been duly authorized to so
execute by all requisite corporate action. The validity and enforceability of
any Subsidiary Guarantee shall not be affected by the fact that it is not
affixed to any particular Note.

          Each of the Guarantors hereby agrees that its Subsidiary Guarantee set
forth in Section 11.01 shall remain in full force and effect notwithstanding any
failure to endorse on each Note a notation of such Subsidiary Guarantee.

          If an Officer of a Guarantor whose signature is on this Indenture or a
Subsidiary Guarantee no longer holds that office at the time the Trustee
authenticates the Note on which such Subsidiary Guarantee is endorsed or at any
time thereafter, such Guarantor's Subsidiary Guarantee of such Note shall
nevertheless be valid.

<Page>

                                      -105-

          The delivery of any Note by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Subsidiary Guarantee set
forth in this Indenture on behalf of each Guarantor.

SECTION 11.05. RELEASE OF A GUARANTOR.

          The Subsidiary Guarantee of a Guarantor will be released:

          (a)     upon the sale or other disposition (including by way of merger
     or consolidation), to any Person that is not an Affiliate of Casella, of
     all of the Capital Stock of that Guarantor held by Casella or any of its
     Restricted Subsidiaries or of all or substantially all of the assets of
     that Guarantor; PROVIDED that such sale or other disposition is made in
     accordance with this Indenture and, if Casella or any of its Restricted
     Subsidiaries intends to comply with the provisions of Section 4.13 by
     purchasing Replacement Assets, Casella delivers to the Trustee a written
     agreement that it will do so within the time frame set forth in Section
     4.13; or

          (b)     if Casella designates such Guarantor as an Unrestricted
     Subsidiary in accordance with this Indenture;

PROVIDED, HOWEVER, in either case that any such termination shall occur only to
the extent that all obligations of such Guarantor under all of its Guarantees of
any Indebtedness of Casella or any Indebtedness of any other Guarantor shall
also terminate upon such release and none of its Equity Interests are pledged
for the benefit of any holder of any Indebtedness of Casella or any Indebtedness
of any Restricted Subsidiary of Casella.

          The Trustee shall execute an appropriate instrument prepared by
Casella evidencing the release of a Guarantor from its obligations under its
Subsidiary Guarantee upon receipt of a request by Casella or such Guarantor
accompanied by an Officers' Certificate and an Opinion of Counsel certifying as
to the compliance with this Section 11.05; PROVIDED, HOWEVER, that the legal
counsel delivering such Opinion of Counsel may rely as to matters of fact on one
or more Officers' Certificates of Casella.

          Except as set forth in Articles Four and Five and this Section 11.05,
nothing contained in this Indenture or in any of the Notes shall prevent any
consolidation or merger of a Guarantor with or into Casella or another Guarantor
or shall prevent any sale or conveyance of the property of a Guarantor as an
entirety or substantially as an entirety to Casella or another Guarantor.

                                      -106-

SECTION 11.06. WAIVER OF SUBROGATION.

          Until this Indenture is discharged and all of the Notes are discharged
and paid in full, each Guarantor hereby irrevocably waives and agrees not to
exercise any claim or other rights which it may now or hereafter acquire against
Casella that arise from the existence, payment, performance or enforcement of
Casella's obligations under the Notes or this Indenture and such Guarantor's
obligations under this Subsidiary Guarantee and this Indenture, in any such
instance including, without limitation, any right of subrogation, reimbursement,
exoneration, contribution, indemnification, and any right to participate in any
claim or remedy of the Holders against Casella, whether or not such claim,
remedy or right arises in equity, or under contract, statute or common law,
including, without limitation, the right to take or receive from Casella,
directly or indirectly, in cash or other assets or by set-off or in any other
manner, payment or security on account of such claim or other rights. If any
amount shall be paid to any Guarantor in violation of the preceding sentence and
any amounts owing to the Trustee or the Holders of Notes under the Notes, this
Indenture, or any other document or instrument delivered under or in connection
with such agreements or instruments, shall not have been paid in full, such
amount shall have been deemed to have been paid to such Guarantor for the
benefit of, and held in trust for the benefit of, the Trustee or the Holders and
shall forthwith be paid to the Trustee for the benefit of itself or such Holders
to be credited and applied to the obligations in favor of the Trustee or the
Holders, as the case may be, whether matured or unmatured, in accordance with
the terms of this Indenture. Each Guarantor acknowledges that it will receive
direct and indirect benefits from the financing arrangements contemplated by
this Indenture and that the waiver set forth in this Section 11.06 is knowingly
made in contemplation of such benefits.

SECTION 11.07. IMMEDIATE PAYMENT.

          Each Guarantor agrees to make immediate payment to the Trustee on
behalf of the Holders of all Guarantee Obligations owing or payable to the
respective Holders upon receipt of a demand for payment therefor by the Trustee
to such Guarantor in writing.

SECTION 11.08. NO SET-OFF.

          Each payment to be made by a Guarantor hereunder in respect of the
Guarantee Obligations shall be payable in the currency or currencies in which
such Guarantee Obligations are denominated, and shall be made without set-off,
counterclaim, reduction or diminution of any kind or nature.

<Page>

                                      -107-

SECTION 11.09. GUARANTEE OBLIGATIONS ABSOLUTE.

          The obligations of each Guarantor hereunder are and shall be absolute
and unconditional and any monies or amounts expressed to be owing or payable by
each Guarantor hereunder which may not be recoverable from such Guarantor on the
basis of a Guarantee shall be recoverable from such Guarantor as a primary
obligor and principal debtor in respect thereof.

SECTION 11.10. GUARANTEE OBLIGATIONS CONTINUING.

          The obligations of each Guarantor hereunder shall be continuing and
shall remain in full force and effect until all such obligations have been paid
and satisfied in full. Each Guarantor agrees with the Trustee that it will from
time to time deliver to the Trustee suitable acknowledgments of this continued
liability hereunder and under any other instrument or instruments in such form
as counsel to the Trustee may advise and as will prevent any action brought
against it in respect of any default hereunder being barred by any statute of
limitations now or hereafter in force and, in the event of the failure of a
Guarantor so to do, it hereby irrevocably appoints the Trustee the attorney and
agent of such Guarantor to make, execute and deliver such written acknowledgment
or acknowledgments or other instruments as may from time to time become
necessary or advisable, in the judgment of the Trustee on the advice of counsel,
to fully maintain and keep in force the liability of such Guarantor hereunder.

SECTION 11.11. GUARANTEE OBLIGATIONS NOT REDUCED.

          The obligations of each Guarantor hereunder shall not be satisfied,
reduced or discharged solely by the payment of such principal, premium, if any,
interest, fees and other monies or amounts as may at any time prior to discharge
of this Indenture pursuant to Article Eight be or become owing or payable under
or by virtue of or otherwise in connection with the Notes or this Indenture.

SECTION 11.12. GUARANTEE OBLIGATIONS REINSTATED.

          The obligations of each Guarantor hereunder shall continue to be
effective or shall be reinstated, as the case may be, if at any time any payment
which would otherwise have reduced the obligations of any Guarantor hereunder
(whether such payment shall have been made by or on behalf of Casella or by or
on behalf of a Guarantor) is rescinded or reclaimed from any of the Holders upon
the insolvency, bankruptcy, liquidation or reorganization of Casella or any
Guarantor or otherwise, all as though such payment had not been made. If demand
for, or acceleration of the time for, payment by Casella or any other Guarantor
is stayed upon the insolvency, bankruptcy, liquidation or reorganization of
Casella or such

<Page>

                                      -108-

Guarantor, all such Indebtedness otherwise subject to demand for payment or
acceleration shall nonetheless be payable by each Guarantor as provided herein.

SECTION 11.13. GUARANTEE OBLIGATIONS NOT AFFECTED.

          The obligations of each Guarantor hereunder shall not be affected,
impaired or diminished in any way by any act, omission, matter or thing
whatsoever, occurring before, upon or after any demand for payment hereunder
(and whether or not known or consented to by any Guarantor or any of the
Holders) which, but for this provision, might constitute a whole or partial
defense to a claim against any Guarantor hereunder or might operate to release
or otherwise exonerate any Guarantor from any of its obligations hereunder or
otherwise affect such obligations, whether occasioned by default of any of the
Holders or otherwise, including, without limitation:

          (a)     any limitation of status or power, disability, incapacity or
     other circumstance relating to Casella or any other Person, including any
     insolvency, bankruptcy, liquidation, reorganization, readjustment,
     composition, dissolution, winding-up or other proceeding involving or
     affecting Casella or any other Person;

          (b)     any irregularity, defect, unenforceability or invalidity in
     respect of any indebtedness or other obligation of Casella or any other
     Person under this Indenture, the Notes or any other document or instrument;

          (c)     any failure of Casella or any other Guarantor, whether or not
     without fault on its part, to perform or comply with any of the provisions
     of this Indenture, the Notes or any Subsidiary Guarantee, or to give notice
     thereof to a Guarantor;

          (d)     the taking or enforcing or exercising or the refusal or
     neglect to take or enforce or exercise any right or remedy from or against
     Casella or any other Person or their respective assets or the release or
     discharge of any such right or remedy;

          (e)     the granting of time, renewals, extensions, compromises,
     concessions, waivers, releases, discharges and other indulgences to Casella
     or any other Person;

          (f)     any change in the time, manner or place of payment of, or in
     any other term of, any of the Notes, or any other amendment, variation,
     supplement, replacement or waiver of, or any consent to departure from, any
     of the Notes or this Indenture, including, without limitation, any increase
     or decrease in the principal amount of or premium, if any, or interest on
     any of the Notes;

          (g)     any change in the ownership, control, name, objects,
     businesses, assets, capital structure or constitution of Casella or a
     Guarantor;

<Page>

                                      -109-

          (h)     any merger or amalgamation of Casella or a Guarantor with any
     Person or Persons;

          (i)     the occurrence of any change in the laws, rules, regulations
     or ordinances of any jurisdiction by any present or future action of any
     governmental authority or court amending, varying, reducing or otherwise

          (j)     any other circumstance, including release of a Guarantor
     pursuant to Section 11.05 (other than by complete, irrevocable payment)

     of its Subsidiary Guarantee hereunder.

SECTION 11.14. WAIVER.

          Without in any way limiting the provisions of Section 11.01, each

          Neither the Trustee nor any other Person shall have any obligation to

obligations under their Subsidiary Guarantees or under this Indenture.

SECTION 11.16. DEALING WITH CASELLA AND OTHERS.

          The Holders, without releasing, discharging, limiting or otherwise

thereunder and hereunder by any remedy provided by law, whether by legal
proceedings or otherwise, and to recover from such Guarantor the obligations.

SECTION 11.18. AMENDMENT, ETC.

          No amendment, modification or waiver of any provision of this

SECTION 11.21. NO MERGER OR WAIVER; CUMULATIVE REMEDIES.

          No Subsidiary Guarantee shall operate by way of merger of any of the
obligations of a Guarantor under any other agreement, including, without
limitation, this Indenture. No failure to exercise and no delay in exercising,
on the part of the Trustee or the Holders, any right, remedy, power or privilege
hereunder or under this Indenture or the Notes, shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder or under this Indenture or the Notes preclude any other or
further exercise thereof or the exercise of any other right, remedy, power or
privilege. The rights, remedies, powers and privileges in the Subsidiary
Guarantee and under this Indenture, the Notes and any other document or
instrument between a Guarantor and/or Casella and the Trustee are cumulative and
not exclusive of any rights, remedies, powers and privilege provided by law.

SECTION 11.22. SURVIVAL OF GUARANTEE OBLIGATIONS.

          Without prejudice to the survival of any of the other obligations of
each Guarantor hereunder, the obligations of each Guarantor under Section 11.01

enforceable against such Guarantor without regard to and without giving effect
to any defense, right of offset or counterclaim available to or which may be
asserted by Casella or any Guarantor.

SECTION 11.23. GUARANTEE IN ADDITION TO OTHER GUARANTEE OBLIGATIONS.

          The obligations of each Guarantor under its Subsidiary Guarantee and

obligations to the Trustee or to any of the Holders in relation to this
Indenture or the Notes and any guarantees or security at any time held by or for
the benefit of any of them.

SECTION 11.24. SEVERABILITY.

          Any provision of this Article Eleven which is prohibited or
unenforceable in any jurisdiction shall not invalidate the remaining provisions
and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction
unless its removal would substantially defeat the basic intent, spirit and
purpose of this Indenture and this Article Eleven.

SECTION 11.25. SUCCESSORS AND ASSIGNS.

          Each Subsidiary Guarantee shall be binding upon and inure to the
benefit of each Guarantor and the Trustee and the other Holders and their

                    9.75% Senior Subordinated Notes due 2013

          Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

          SECTION 1. INTEREST. Casella Waste Systems, Inc., a Delaware
corporation ("CASELLA"), promises to pay interest on the principal amount of
this Note at 9.75% per annum from January 24, 2003 until maturity. Casella will
pay interest semi-annually on February 1 and August 1 of each year, or if any
such day is not a Business Day, on the next succeeding Business Day (each an
"INTEREST PAYMENT DATE"), commencing August 1, 2003. Interest on the Notes will
accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of original issuance; PROVIDED that if
there is no existing Default in the payment of interest, and if this Note is
authenticated between a record date referred to on the face hereof and the next
succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date. Casella shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal and premium, if any, from time to time on demand to the extent lawful
at the interest rate applicable to the Notes; it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest (without regard to any applicable grace periods) from
time to time on demand at the same rate to the extent lawful. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

          SECTION 2. METHOD OF PAYMENT. Casella will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the January 15 or July 15 next preceding the
Interest Payment Date, even if such Notes are canceled after such record date
and on or before such Interest Payment Date, except as provided in Section 2.12
of the Indenture with respect to defaulted interest. The Notes will be issued in
denominations of $1,000 and integral multiples thereof. Casella shall pay
principal, premium, if any, and interest on the Notes in such coin or currency
of the United States of America as at the time of payment is legal tender for
payment of public and private debts ("U.S. LEGAL TENDER"). Principal, premium,
if any, and interest on the Notes will be payable at the office or agency of
Casella maintained for such purpose or, at the option of Casella, payment of
interest may be made by check mailed to the Holders of the Notes at their
respective addresses set forth in the register of Holders of Notes; PROVIDED
that all payments of principal, premium and interest with respect to Notes the
Holders of which have given wire transfer instructions to Casella prior to the
Record Date will be required to be made by wire transfer of immediately
available funds to the accounts specified by the Holders thereof. Until
otherwise designated by Casella, Casella's office or agency in New York will be
the office of the Trustee maintained for such purpose.

                                       A-4
<Page>

          SECTION 3. PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National
Association, the Trustee under the Indenture, will act as Paying Agent and
Registrar. Casella may change any Paying Agent or Registrar without notice to
any Holder. Casella or any of its Subsidiaries may act in any such capacity.

          SECTION 4. INDENTURE AND SUBORDINATION. Casella issued the Notes under
an Indenture dated as of January 24, 2003 ("INDENTURE") by and among Casella,
the Guarantors and the Trustee. The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb) (the
"TIA"). The Notes are subject to all such terms, and Holders are referred to the
Indenture and the TIA for a statement of such terms. To the extent any provision
of this Note conflicts with the express provisions of the Indenture, the
provisions of the Indenture shall govern and be controlling. The payment of the
Notes will, to the extent set forth in the Indenture, be subordinated in right
of payment to the prior payment in full in cash or cash equivalents of all
Senior Debt.

          SECTION 5. OPTIONAL REDEMPTION. Except as set forth in Section 6
hereof, the Notes will not be redeemable at Casella's option prior to February
1, 2008. On or after February 1, 2008, the Notes will be subject to redemption
at any time at the option of Casella, in whole or in part, upon not less than 30
nor more than 60 days' notice, at the redemption prices (expressed as
percentages of principal amount) set forth below plus accrued and unpaid
interest thereon, if any, to the applicable redemption date, if redeemed during
the twelve-month period beginning on February 1 of the years indicated below:

          ----                                                  ----------
          <S>                                                    <C>
          2008..........................................         104.875%
          2009..........................................         103.250%
          2010..........................................         101.625%
          2011 and thereafter...........................         100.000%
</Table>

          SECTION 6. OPTIONAL REDEMPTION UPON PUBLIC EQUITY OFFERING. At any
time on or prior to February 1, 2006, Casella may on any one or more occasions
redeem up to 35% of the aggregate principal amount of Notes issued under the
Indenture at a redemption price equal to 109.750% of the principal amount
thereof, plus accrued and unpaid interest thereon, if any, to the redemption
date, with the net cash proceeds of Public Equity Offerings by Casella; PROVIDED
that (i) at least 65% of the aggregate principal amount of Notes issued under
the Indenture remains outstanding immediately after the occurrence of such
redemption (excluding Notes held by Casella and its Subsidiaries) and (ii) such
redemption shall occur within 90 days of the date of the closing of such Public
Equity Offering (disregarding the date of the closing of any over-allotment
option with respect thereto).

                                       A-5
<Page>

          SECTION 7. MANDATORY REDEMPTION. For the avoidance of doubt, an offer
to purchase pursuant to Section 8 hereof shall not be deemed a redemption.
Casella shall not be required to make mandatory redemption payments with respect
to the Notes.

          SECTION 8. REPURCHASE AT OPTION OF HOLDER. Upon the occurrence of a
Change of Control, and subject to certain conditions set forth in the Indenture,
Casella will be required to offer to purchase all of the outstanding Notes at a
purchase price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest, if any, thereon to the date of repurchase.

          Casella is, subject to certain conditions and exceptions, obligated to
make an offer to purchase Notes at 100% of their principal amount, plus accrued
and unpaid interest, if any, thereon to the date of repurchase, with certain net
cash proceeds of certain sales or other dispositions of assets in accordance
with the Indenture.

          SECTION 9. NOTICE OF REDEMPTION. Notice of redemption will be mailed
by first class mail at least 30 days but not more than 60 days before the
redemption date to each Holder of Notes to be redeemed at its registered
address. Notes in denominations larger than $1,000 may be redeemed in part. If
any Note is to be redeemed in part only, the notice of redemption that relates
to such Note shall state the portion of the principal amount thereof to be
redeemed. A new Note in principal amount equal to the unredeemed portion thereof
will be issued in the name of the Holder thereof upon cancellation of the
original Note. On and after the redemption date interest ceases to accrue on
Notes or portions thereof called for redemption.

          SECTION 10. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and Casella may require a Holder to pay any taxes and fees
required by law or permitted by the Indenture. Casella or the Registrar is not
required to transfer or exchange any Note selected for redemption. Also, Casella
or the Registrar is not required to transfer or exchange any Notes for a period
of 15 days before a selection of Notes to be redeemed.

          SECTION 11. PERSONS DEEMED OWNERS. The registered Holder of a Note may
be treated as its owner for all purposes.

          SECTION 12. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
exceptions, the Indenture and the Notes may be amended or supplemented with the
written consent of the Holders of at least a majority in aggregate principal
amount of the Notes then outstanding, and any existing Default or compliance
with any provision may be waived with the consent of the Holders of a majority
in aggregate principal amount of the Notes then outstanding.

                                       A-6
<Page>

Without notice to or consent of any Holder, the parties thereto may amend or
supplement the Indenture and the Notes to, among other things, cure any
ambiguity, defect or inconsistency in the Indenture, provide for uncertificated
Notes in addition to certificated Notes, comply with any requirements of the
Commission in connection with the qualification of the Indenture under the TIA,
or make any change that does not adversely affect the rights of any Holder of a
Note.

          SECTION 13. DEFAULTS AND REMEDIES. If a Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes generally may declare all the Notes to be due and
payable immediately. Notwithstanding the foregoing, in the case of a Default
arising from certain events of bankruptcy or insolvency as set forth in the
Indenture, with respect to Casella or any Significant Subsidiary, all
outstanding Notes will become due and payable without further action or notice.
Holders of the Notes may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in principal amount of the then outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
Notes notice of any continuing Default (except a Default relating to the payment
of principal or interest) if it determines that withholding notice is in their
interest. The Holders of a majority in aggregate principal amount of the Notes
then outstanding by notice to the Trustee may on behalf of the Holders of all of
the Notes waive any existing Default and its consequences under the Indenture
except a continuing Default in the payment of interest on, or the principal of,
or the premium on, the Notes.

          SECTION 14. RESTRICTIVE COVENANTS. The Indenture contains certain
covenants that, among other things, limit the ability of Casella and its
Restricted Subsidiaries to make restricted payments, to incur indebtedness, to
create liens, to sell assets, to permit restrictions on dividends and other
payments by Restricted Subsidiaries of Casella, to consolidate, merge or sell
all or substantially all of its assets or to engage in transactions with
affiliates. The limitations are subject to a number of important qualifications
and exceptions. Casella must annually report to the Trustee on compliance with
such limitations.

          SECTION 15. NO RECOURSE AGAINST OTHERS. No director, officer,
employee, incorporator or stockholder of Casella or any Guarantor, as such,
shall have any liability for any obligations of Casella or the Guarantors under
the Notes, the Indenture, the Guarantors' Subsidiary Guarantees or for any claim
based on, in respect of, or by reason of, such obligations or their creation.
Each Holder of Notes by accepting a Note waives and releases all such liability.
The waiver and release are part of the consideration for issuance of the Notes.

          SECTION 16. SUBSIDIARY GUARANTEES. This Note will be entitled to the
benefits of certain Subsidiary Guarantees made for the benefit of the Holders.
Reference is hereby made to the Indenture for a statement of the respective
rights, limitations of rights, duties and obligations thereunder of the
Guarantors, the Trustee and the Holders.

                                       A-7
<Page>

          SECTION 17. TRUSTEE DEALINGS WITH CASELLA. The Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of Notes and may otherwise deal with Casella, its Subsidiaries or their
respective Affiliates as if it were not the Trustee.

          SECTION 18. AUTHENTICATION. This Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

          SECTION 19. ABBREVIATIONS. Customary abbreviations may be used in the
name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT
(= tenants by the entirety), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

          SECTION 20. ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES
AND RESTRICTED DEFINITIVE NOTES. Pursuant to, but subject to the exceptions in,
the Exchange and Registration Rights Agreement, Casella and the Guarantors will
be obligated to consummate an exchange offer pursuant to which the Holder of
this Note shall have the right to exchange this Note for a 9.75% Senior
Subordinated Note due 2013 of Casella which shall have been registered under the
Securities Act, in like principal amount and having terms identical in all
material respects to this Note (except that such note shall not be entitled to
Liquidated Damages). The Holders shall be entitled to receive certain Liquidated
Damages in the event such exchange offer is not consummated or the Notes are not
offered for resale and upon certain other conditions, all pursuant to and in
accordance with the terms of the Exchange and Registration Rights Agreement.(a)

          SECTION 21. CUSIP NUMBERS. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, Casella has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS TO THE EXTENT THAT THE
APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

charge a copy of the Indenture.

Ladies and Gentlemen:

          In connection with our proposed purchase of 9.75% Senior Subordinated
Notes due 2013 (the "Notes") of CASELLA WASTE SYSTEMS, INC., a Delaware
corporation ("Casella"), we confirm that:

          1.      We have received a copy of the Offering Circular (the
"Offering Circular"), dated January 21, 2003, relating to the Notes and such
other information as we deem necessary in order to make our investment decision.
We acknowledge that we have read and agreed to the matters stated in the section
entitled "Notice to Investors" of such Offering Circular, including the
restrictions on duplication and circulation of the Offering Circular.

          2.      We understand that any subsequent transfer of the Notes is
subject to certain restrictions and conditions set forth in the Indenture
relating to the Notes (the "Indenture") as described in the Offering Circular
and the undersigned agrees to be bound by, and not to resell, pledge or
otherwise transfer the Notes except in compliance with, such restrictions and
conditions and the Securities Act of 1933, as amended (the "Securities Act"),
and all applicable State securities laws.

          3.      We understand that the offer and sale of the Notes have not
been registered under the Securities Act, and that the Notes may not be offered
or sold except as permitted in the following sentence. We agree, on our own
behalf and on behalf of any accounts for which we are acting as hereinafter
stated, that if we should sell any Notes, we will do so only (i) to Casella or
any of its subsidiaries, (ii) inside the United States in accordance with Rule
144A under the Securities Act to a "qualified institutional buyer" (as defined
in Rule 144A under the Securities Act), (iii) inside the United States to an
institutional "accredited investor"

                                       C-1
<Page>

(as defined below) that, prior to such transfer, furnishes (or has furnished on
its behalf by a U.S. broker-dealer) to the Trustee (as defined in the Indenture)
a signed letter containing certain representations and agreements relating to
the restrictions on transfer of the Notes (the form of which letter can be
obtained from the Trustee), (iv) outside the United States in accordance with
Regulation S promulgated under the Securities Act to non-U.S. persons, (v)
pursuant to the exemption from registration provided by Rule 144 under the
Securities Act (if available), (vi) in accordance with another exemption from
the registration requirements of the Securities Act (and based upon an opinion
of counsel if Casella so requests) or (vii) pursuant to an effective
registration statement under the Securities Act, and we further agree to provide
to any person purchasing any of the Notes from us a notice advising such
purchaser that resales of the Notes are restricted as stated herein.

          4.      We are not acquiring the Notes for or on behalf of, and will
not transfer the Notes to, any pension or welfare plan (as defined in Section 3
of the Employee Retirement Income Security Act of 1974, as amended) or plan (as
defined in Section 4975 of the Internal Revenue Code of 1986, as amended),
except as permitted in the section entitled "Notice to Investors" of the
Offering Circular.

          5.      We understand that, on any proposed resale of any Notes, we
will be required to furnish to the Trustee and Casella such certification, legal
opinions and other information as the Trustee and Casella may reasonably require
to confirm that the proposed sale complies with the foregoing restrictions. We
further understand that the Notes purchased by us will bear a legend to the
foregoing effect.

          6.      We are an institutional "accredited investor" (as defined in
Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and
have such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risks of our investment in the Notes, and
we and any accounts for which we are acting are each able to bear the economic
risk of our or their investment, as the case may be.

          7.      We are acquiring the Notes purchased by us for our account or
for one or more accounts (each of which is an institutional "accredited
investor") as to each of which we exercise sole investment discretion.
