Ladies and Gentlemen:

       An  Agreement  and Plan of  Merger  dated as of  January  12,  1999  (the
"Agreement"),  as amended as of May 12, 1999,  September  8, 1999 and  September
___,  1999,  has  been  entered  into  by and  among  KTI,  Inc.,  a New  Jersey
corporation  ("Seller"),  Casella Waste  Systems,  Inc., a Delaware  corporation
("Buyer"),  and Rutland  Acquisition  Sub, Inc., a New Jersey  corporation and a
wholly-owned  subsidiary of Buyer (the "Merger Sub"). The Agreement provides for
the merger of the Merger Sub with and into Seller (the "Merger").  In accordance
with the Agreement,  shares of common stock,  no par value per share,  of Seller
(the "Seller Common Stock") shall be converted into shares of common stock, $.01
par value per share,  of Buyer (the "Buyer Common  Stock"),  as described in the
Agreement.

       The  undersigned  has been advised that as of the date of this  agreement
the  undersigned  may be  deemed to be an  "affiliate"  of  Seller,  as the term
"affiliate" is defined for purposes of paragraphs (c) and (d) of Rule 145 of the
Rules  and   Regulations  of  the  Securities  and  Exchange   Commission   (the
"Commission")  under the  Securities  Act of 1933,  as amended (the  "Securities
Act").

       In consideration of the mutual  agreements,  provisions and covenants set
forth in the  Agreement  and  hereinafter  in this  agreement,  the  undersigned
represents and agree as follows:

       1.  Amendment  and  Restatement.  This  letter  amends and  restates  and
supersedes in its entirety the Affiliate  Agreement among Seller,  Buyer and the
undersigned  dated as of January 12, 1999, which shall be of no further force or
effect.

       2. Rule 145. The undersigned will not offer, sell,  pledge,  hypothecate,
transfer or otherwise dispose of, or reduce its interest in or risk relating to,
any of the shares of Buyer Common Stock issued to the  undersigned in the Merger
unless at such time either:  (i) such  transaction is permitted  pursuant to the
provisions of Rule 145 under the Securities Act; (ii) the undersigned shall have
furnished to Buyer an opinion of counsel,  reasonably  satisfactory  to Buyer to
the effect that such  transaction  is  otherwise  exempt  from the  registration
requirements of the Securities Act; or (iii) a registration  statement under the
Securities  Act  covering  the  proposed  offer,  sale,  pledge,  hypothecation,
transfer or other disposition shall be effective under the Securities Act.

       3. Legend.

       (a) The undersigned understands that all certificates  representing Buyer
Common Stock  delivered to the  undersigned  pursuant to the Merger shall bear a
legend in substantially the form set forth below,  until the earlier to occur of
(i) one of the events  referred  to in Section 2 above or (ii) the date on which
the undersigned  requests  removal of such legend,  provided,  that such request
occurs at least two years from the Effective  Time (as defined in the Agreement)
and that the  undersigned  is not at the time of such request,  and has not been
during the three months period preceding to such request, an affiliate of Buyer.

                "The shares  represented  by this  certificate  were issued in a
                transaction  to  which  Rule 145 of the  Securities  Act of 1933
                applies  and may  only be  transferred  in  accordance  with the
                provisions of such rule. In addition,  the shares represented by
                this  certificate may only be transferred in accordance with the
                terms  of an  affiliate  agreement  dated  September  ___,  1999
                between the  initial  holder  hereof and Buyer,  a copy of which
                agreement may be inspected by the holder of this  certificate at
                the  principal  offices of Buyer,  or  furnished by Buyer to the
                holder of this certificate upon written request without charge."

       (b) Buyer in its discretion  may cause stop transfer  orders to be placed
with its transfer agent with respect to the certificates for the shares of Buyer
Common Stock that are required to bear the foregoing legend.

       4. General Provisions.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE  WITH THE LAWS OF THE STATE OF DELAWARE,  WITHOUT GIVING EFFECT TO
PRINCIPLES  OF  CONFLICTS  OF  LAWS.  This  agreement  shall be  binding  on the
undersigned's successors and assigns,  including his or her heirs, executors and
administrators.

       Execution  of this letter  should not be  considered  an admission on the
part of the  undersigned  that the  undersigned  is an  "affiliate" of Seller as
described in the second  paragraph of this letter,  or as a waiver of any rights
the undersigned may have to object to, or any claim that the undersigned is such
an affiliate on or after the date of this letter.









       The  undersigned  has  carefully  read this  agreement  and discussed its
requirements, to the extent the undersigned believed necessary, with its counsel
or counsel for Buyer.

                                              Very truly yours,


                                              __________________________________
