duty based upon an act or omission (a) in breach of such person's duty of
loyalty to the Corporation or its shareholders, (b) not in good faith or
involving a knowing violation of law or (c) resulting in receipt by such person
of an improper personal benefit. Neither the amendment or repeal of this Article
SIXTH, nor the adoption of any provision of this Restated Certificate of
Incorporation inconsistent with this Article SIXTH shall eliminate or reduce the

to time permitted by law, any person made, or threatened to be made, a party to,
or a witness or other participant in, any threatened, pending, or completed
action, suit or proceeding, whether civil, criminal, administrative,
arbitrative, legislative, investigative, or of any other kind, by reason of the
fact that such person is or was a corporate agent of the Corporation or any
subsidiary of the Corporation or serves or served any other enterprise at the
request of the Corporation (including specifically, but not limited to, service
as a fiduciary with respect to any employee benefit plan) against expenses
(including attorneys' fees), judgments, fines, penalties, excise taxes, and
amounts paid in settlement (including amounts paid pursuant to judgments or
settlements in derivative actions), actually and reasonably incurred by such
person in connection with such action, suit, or proceeding, or any appeal
therein. The rights provided by this Article SEVENTH to any person shall inure
to the benefit of such person's legal representative. Neither amendment or
repeal of this Article SEVENTH, nor the adoption of any provision of this
Restated Certificate of Incorporation inconsistent with this Article SEVENTH,
shall deprive any person of rights hereunder arising out of any matter which
occurred prior to such amendment, repeal or adoption. No indemnification
pursuant to

                                      - 4 -

this Article shall be required with respect to any settlement or other
nonadjudicated disposition of any threatened or pending action or proceeding
unless the Corporation has given its prior consent to such settlement or other
disposition.

          B.   As used in this Article "corporate agent" means any person who is
or was a director, officer, employee or agent of the Corporation or of any

any such constituent corporation, or the legal representative of any such
director, officer, trustee, employee or agent.

          C.   The Corporation shall have the authority to purchase and maintain

participant because of their service to the Corporation, any subsidiary of the
Corporation or any other enterprise at the request of the Corporation.

          D.   To the full extent from time to time permitted by law, expenses
incurred by a person in defending a civil or criminal action, suit or proceeding
shall be paid by the Corporation in advance of the final disposition of such
action upon receipt of an undertaking by or on behalf of such person to repay
such amount to the extent the expenses so advanced exceed the indemnification to
which it is ultimately determined that he is entitled.

                                 ARTICLE EIGHTH

               A.   The merger or consolidation of the Corporation with any
other corporation or the sale, lease, exchange or other disposition of all or
substantially all the assets of the Corporation may be effected only if, in

shall have been approved by the affirmative vote of not less than eighty percent

Directors; and provided, further, that this Article EIGHTH shall not be

Board of Directors of the Corporation, while such person is a member of the
Board of Directors, who is not an Affiliate, Associate or representative of any
party to the transaction (other than the Corporation or a corporation all of the
capital stock of which, except for directors' qualifying shares, is beneficially
owned directly or indirectly by the Corporation) and either was a member of the
Board of Directors on the date of approval of this Article EIGHTH by the Board
or was recommended for election to the Board of Directors, or elected to fill a
vacancy on the Board, by a majority of Disinterested Directors.

               2.   The terms "Voting Stock", "Affiliate" and "Associate" have
the meanings set forth in Article NINTH hereof.

               C.   A majority of the Disinterested Directors shall have the
power and duty to determine for the purposes of this Article EIGHTH, on the
basis of information known to them after reasonable inquiry, all facts necessary
to determine compliance with this Article EIGHTH.

               D.   The affirmative vote of not less than eighty percent (80%)
of the votes entitled to be cast by the holders of all then outstanding shares
of Voting Stock, voting together as a single class, shall be required to amend
or repeal, or adopt any provisions inconsistent with, this Article EIGHTH.

that no vote may be required, or that a lesser percentage or separate class vote
may be specified, by law or otherwise.

               affairs of the Corporation, regardless of whether the Business
               Combination, to be consummated constitutes each an event.

          The provisions of this Paragraph 2(b) shall be required to be met with
          respect to every class or series of outstanding Capital Stock other

          class or series of Capital Stock.

                    (c)  The consideration to be received by holders of a
          particular class or series of outstanding Capital Stock shall be in
          cash or in the same form as previously has been paid by or on behalf
          of the Interested Shareholder in connection with its direct or
          indirect acquisition of beneficial ownership of shares of such class
          or series of Capital Stock. If the consideration so paid for shares of
          any class or series of Capital Stock varied as to form, the form of
          consideration for such class or series of Capital Stock shall be
          either cash or the form used to acquire beneficial ownership of the
          largest number of shares of such class or series of Capital Stock
          previously acquired by the Interested Shareholder.

                    (d)  After such Interested Shareholder has become an
          Interested Shareholder and prior to the consummation of such Business
          Combination: (i) except as approved by a majority of the Continuing
          Directors,

                                      - 9 -
<Page>

          there shall have been no failure to declare and pay at the regular
          date therefor any full quarterly dividends (whether or not cumulative)
          payable in accordance with the terms of any outstanding Capital Stock;
          (ii) there shall have been (x) no reduction in the annual rate of
          dividends paid on the Common Stock (except as necessary to reflect any
          stock dividend or subdivision of the Common Stock) other than as
          approved by a majority of the Continuing Directors and (y) an increase
          in such annual rate of dividends as necessary to prevent any such
          reduction in the event of any reclassification (including any reverse
          stock split), recapitalization, reorganization or any similar
          transaction which has the effect of reducing the number of outstanding
          shares of Common Stock, unless the failure so to increase such annual
          rate is approved by a majority of the Continuing Directors; (iii) such
          Interested Shareholder shall not have become the beneficial owner of
          any additional shares of Capital Stock except as part of the
          transaction that results in such Interested Shareholder becoming an
          Interested Shareholder and except in a transaction that, after giving
          effect thereto, would not result in any increase in the Interested
          Shareholder's percentage beneficial ownership of any class or series
          of Capital Stock.

                    (e)  After such Interested Shareholder has become an
          Interested Shareholder, such Interested Shareholder shall not have
          received the benefit, directly or indirectly (except proportionately
          as a shareholder of the Corporation), of any loans, advances,
          guarantees, pledges or other financial assistance or any tax credits
          or other tax advantages provided by the Corporation or any Subsidiary

               F.   EFFECT ON OBLIGATIONS OF BOARD OF DIRECTORS. The fact that

Article NINTH shall not be construed to impose any fiduciary duty, obligation or
responsibility on the Board of Directors, or any member thereof, to approve such
Business Combination or recommend its adoption or approval to the shareholders
of the Corporation, nor shall such compliance limit, prohibit or otherwise
restrict in any manner the Board of Directors, or any member thereof, with
respect to evaluations of or actions and responses taken with respect to such
Business Combination.

Article NINTH.

                                                                  JUN 2 1997

                                                                LONNA R. HOOKS
                                                              Secretary of State

                         CERTIFICATE OF AMENDMENT TO THE
                      RESTATED CERTIFICATE OF INCORPORATION
                                  OF KTI, INC.

     Pursuant to the provisions of Sections 14A:7-2(4) and 14A:9-2(2),
Corporations, General, of the New Jersey Statutes, the undersigned Corporation
executes the following Certificate of Amendment to its Restated Certificate of
Incorporation:

     1.   The name of the corporation is KTI, Inc. (the "Corporation").

     2.   The following resolution was adopted by the Board of Directors of the
Corporation:

     Resolved that a new ARTICLE TENTH relating to the designation, number
rights, preferences and limitations of a series of preferred stock shall be
added to the Restated Certificate of Incorporation, as amended, and shall read
in its entirety as follows:

                                 "ARTICLE TENTH

     Section 1.    DESIGNATION AND AMOUNT. The series of Preferred Stock
designated and known as the "Series A Preferred" shall have no par value and the
number of shares constituting the Series A Preferred shall be 487,500.

     Section 2.    RANK. The Series A Preferred shall rank: (i) prior to all of
the Company's Common Stock, no par value ("Common"); (ii) PARI PASSU with any
class or series of convertible Preferred Stock or other capital stock of the
Company hereafter created, which is convertible into Common or which, when
originally issued, was issued simultaneously with Common purchase warrants; and
(iii) junior to any class of preferred stock which is not convertible into any
other class of securities of the Company ("Senior Securities"), in each case as
to distributions of assets upon liquidation, dissolution or winding up of the
Company, whether voluntary or involuntary (all such distributions being referred
to collectively as "Distributions").

     Section 3.    DIVIDENDS. If any dividend or other distribution payable in
cash, securities or other property (other than securities of the Company the
issuance of which gives rise to adjustment of the Conversion Price as set forth
below) is declared on the Common, each holder of shares of Series A Preferred on
the record date for such dividend or distribution shall be entitled to receive
on the date of payment or distribution of such dividend or other distribution
the same cash, securities or other property which such holder would have
received on such record date if such holder was the holder of record of the
number (including any fraction) of shares of Common into which the shares of
Series A Preferred then held by such holder are then convertible.

     Section 4.    LIQUIDATION PREFERENCE.

     (a)  In the event of any liquidation, dissolution or winding up of the
Company, either voluntary or involuntary, the holders of Series A Preferred (the
"Holders"), shall be entitled to receive, prior to any payment with respect to
any shares of Common but after any

S253306
J472614
                                                                      0100279875

<Page>

payment with respect to any outstanding shares of Senior Securities, an amount
per share (the "Liquidation Preference") equal to the sum of (i) $8.00 for each
outstanding share of Series A Preferred, plus (ii) interest of 8.19 percent per
annum calculated based on the number of actual days elapsed in a 365 day year or
a 366 day year, as appropriate, plus (iii) any dividends which have been
declared and which the Holders are entitled to receive with respect to each
share of Series A Preferred. If upon the occurrence of such event, the assets
and funds available to be distributed among the Holders shall be insufficient to
permit the payment to such Holders of the full preferential amounts due to such
Holders, then the entire assets and funds of the Company legally available for
distribution to such Holders and the holders of securities PARI PASSU with the
Series A Preferred shall be distributed among the Holders and holders of such
PARI PASSU securities on a pro rata basis.

     Section 5.    CONVERSION. The record Holders of Series A Preferred shall
have conversion rights as follows (the "Conversion Rights"):

     (a)  RIGHT TO CONVERT.

          (i)      Each record Holder of Series A Preferred shall be entitled to
convert shares of Series A Preferred at any time into that number of fully-paid
and non-assessable shares of Common of the Company calculated in accordance with
the following formula (the "Conversion Rate"):

      Number of shares issued upon conversion of one (1) share of Series A
                                  Preferred =

                             Liquidation Preference
                          ---------------------------
                                Conversion Price

where "Conversion Price" means $8.00, as adjusted herein.

     (b)  ADJUSTMENTS TO CONVERSION PRICE. The Conversion Price shall be subject
to adjustment from time to time upon the occurrence of certain events described
in this SECTION 5(b).

          (i)      SUBDIVISION OR COMBINATION OF COMMON AND COMMON DIVIDEND. In
case the Company shall at any time subdivide its outstanding Common into a
greater number of shares or declare a dividend upon the Common payable solely in
shares of Common, the Conversion Price in effect immediately prior to such
subdivision or declaration shall be proportionately reduced. Conversely, in case
the outstanding Common shall be combined into a smaller number of shares of
Common, the Conversion Price in effect immediately prior to such combination
shall be proportionately increased.

          (ii)     ADJUSTMENT DUE TO MERGER, CONSOLIDATION, ETC. If, prior to
the conversion of all Series A Preferred, there shall be any merger,
consolidation, exchange of shares, recapitalization, reorganization, or other
similar event, and as a result of which shares of Common of the Company shall be
changed into the same or a different number of shares of the same or another
class or classes of stock or securities of the Company or another entity, or
other property, the Holders shall, be given at least 30 days advance written
notice of such transaction. The Holders shall then have the right to purchase
and receive

<Page>

upon conversion of Series A Preferred, upon the basis and subject to the terms
and conditions specified herein and in lieu of the shares of Common immediately
theretofore issuable upon conversion, such shares of stock and/or securities or
other property as may be issued or payable with respect to or in exchange for
the number of shares of Common immediately theretofore purchasable and
receivable upon the conversion of Series A Preferred held by such Holders had
such merger, consolidation, exchange of shares, recapitalization or
reorganization not taken place. In any such case appropriate provisions shall be
made with respect to the rights and interests of the Holders to the end that the
provisions hereof (including, without limitation, provisions for adjustment of
the Conversion Rate and of the number of shares issuable upon conversion of the
Series A Preferred) shall thereafter be applicable, as nearly as may be
practicable in relation to any shares of stock or securities thereafter
deliverable upon the conversion thereof. The Company shall not effect any
transaction described in this SUBSECTION 5(b)(ii) unless (1) each Holder has
been given at least 20 days advance written notice of such transaction, and (2)
the resulting successor or acquiring entity (if not the Company) assumes by
written instrument the obligation to deliver to the Holders such shares of stock
and/or securities or other property as, in accordance with the foregoing
provisions, the Holders of may be entitled to receive upon conversion of the
Series A Preferred. Notwithstanding the foregoing, if any of the events
described herein constitutes a Change in Control Transaction, the Holders shall
have the option, exercisable by written notice to the Company, to receive the
Liquidation Preference for their shares of Series A Preferred pursuant to
SECTION 4(b) above in lieu of their rights under this SECTION 5(b)(ii).

          (iii)    DILUTIVE ISSUANCES. If the Company shall sell or issue at any
time shares of Common (other than Excluded Securities, as defined in SECTION
5(b)(viii) below) at a consideration per share less than the Conversion Price
then in effect, the Conversion Price shall be adjusted to a new Conversion Price
(calculated to the nearest cent) determined by dividing:

                   (A)  an amount equal to (i) the total number of "Shares
Outstanding" (as defined below) immediately prior to such issuance, multiplied
by the Conversion Price in effect immediately prior to such issuance plus (ii)
the aggregate of the amount of all consideration, if any, received by the
Company upon such issuance; by

                   (B)  the total number of Shares Outstanding immediately after
such issuance or sale.

In no event shall any such adjustment be made pursuant to this SECTION 5(b)(iii)
if it would increase the Conversion Price in effect immediately prior to such
adjustment, except as provided in SECTIONS 5(b)(vi) AND 5(b)(vii).

          (iv)     DEFINITIONS. For purposes of this SECTION 5(b), the following
definitions shall apply:

                   (A)  "CONVERTIBLE SECURITIES" means any indebtedness or
securities convertible into or exchangeable for Common.

<Page>

                   (B)  "OPTIONS" means any rights, warrants or options to
subscribe for or purchase Common or Convertible Securities other than rights,
warrants or options to purchase Excluded Securities (as defined in SECTION
5(b)(viii)).

                   (C)  "SHARES OUTSTANDING" means the aggregate of all shares
of Common outstanding and all Common issuable upon exercise of all outstanding
Options and conversion of all outstanding Convertible Securities.

          (v)      ADJUSTMENTS. For the purposes of this SECTION 5(b), the
following provisions shall also be applicable:

                   (A)  CASH CONSIDERATION. In case of the issuance or sale of
additional shares of Common for cash, the consideration received by the Company
therefor shall be deemed to be the amount of cash received by the Company from
the recipients or purchasers of the additional shares of Common for such shares
of Common.

                   (B)  NON-CASH CONSIDERATION. In case of the issuance
(otherwise than upon conversion or exchange of Convertible Securities) or sale
of additional shares of Common, Options or Convertible Securities for a
consideration other than cash or a consideration a part of which shall be other
than cash, the fair value of such consideration as determined by the Board of
Directors of the Company in the good faith exercise of its business judgment,
irrespective of the accounting treatment thereof, shall be deemed to be the
value of the consideration other than cash received by the Company for such
securities.

                   (C)  OPTIONS AND CONVERTIBLE SECURITIES. In case the Company
shall in any manner issue or grant any Options or any Convertible Securities,
the total maximum number of shares of Common issuable upon the exercise of such
Options or upon conversion or exchange of the total maximum amount of such
Convertible Securities (in each case, without giving effect to any future
operation of any anti-dilution clauses in any such Option or Convertible
Securities at the time of such issuance or grant) at the time such Convertible
Securities first become convertible or exchangeable shall (as of the date of
issue or grant of such Options or, in the case of the issue or sale of
Convertible Securities other than where the same are issuable upon the exercise
of Options, as of the date of such issue or sale) be deemed to be issued and to
be outstanding for the purpose of this SECTION 5(b) and to have been issued for
the sum of the amount (if any) paid for such Options or Convertible Securities
and the amount (if any) payable upon the exercise of such Options or upon
conversion or exchange of such Convertible Securities at the time such
Convertible Securities first become convertible or exchangeable; PROVIDED that,
subject to the provisions of SECTION 5(b)(vi), no further adjustment of the
Conversion Price shall be made upon the actual issuance of any such shares of
Common or Convertible Securities or upon the conversion or exchange of any such
Convertible Securities.

          (vi)     CHANGE IN OPTION PRICE OR CONVERSION RATE. If the purchase
price provided for in any Option referred to in SUBSECTION 5(b)(v)(C), or the
rate at which any Convertible Securities referred to in SUBSECTION 5(b)(v)(C)
are convertible into or exchangeable for shares of Common shall change at any
time (other than under or by reason of provisions designed to protect against
dilution), then, for purposes of any adjustment required by SECTION 5(b), the
Conversion Price in effect at the time of such event shall

<Page>

forthwith be readjusted to the Conversion Price that would have been in effect
at such time had such Options or Convertible Securities still outstanding
provided for such changed purchase price, additional consideration or conversion
rate, as the case may be, at the time initially granted, issued or sold,
provided that if such readjustment is an increase in the Conversion Price, such
readjustment shall not exceed the amount (as adjusted by SECTIONS 5(b)(i) AND
5(b)(v)) by which the Conversion Price was decreased pursuant to
SECTION 5(b)(ii) upon the issuance of the Option or Convertible Security. If the
purchase price provided for in any such Option referred to in SUBSECTION
5(b)(v)(C), or the additional consideration (if any) payable upon the conversion
or exchange of any Convertible Securities referred to in SUBSECTION 5(b)(v)(C),
or the rate at which any Convertible Securities referred to in
SUBSECTION 5(b)(v)(C) are convertible into or exchangeable for shares of Common,
shall be reduced at any time under or by reason of provisions with respect
thereto designed to protect against dilution, then in case of the delivery of
shares of Common upon the exercise of any such Option or upon conversion or
exchange of any such Convertible Security; the Conversion Price then in effect
hereunder shall, upon issuance of such shares of Common be adjusted to such
amount as would have obtained had such Option or Convertible Security never been
issued and had adjustments been made only upon the issuance of the shares of
Common delivered as aforesaid and for the consideration actually received for
such Option or Convertible Security and the shares of Common, provided that if
such readjustment is an increase in the Conversion Price, such readjustment
shall not exceed the amount (as adjusted by SECTIONS 5(b)(i) and 5(b)(iii) by
which the Conversion Price was decreased pursuant to SECTION 5(b)(iii) upon the
issuance of the Option or Convertible Security.

          (vii)    TERMINATION OF OPTION OR CONVERSION RIGHTS. In the event of
the termination or expiration of any right to purchase shares of Common under
any Option granted after the date hereof or of any right to convert or exchange
Convertible Securities issued after the date hereof, the Conversion Price shall,
upon such termination, be readjusted to the Conversion Price that would have
been in effect at the time of such expiration or termination had such Option or
Convertible Security, to the extent outstanding immediately prior to such
expiration or termination, never been issued, and the shares of Common issuable
thereunder shall no longer be deemed to be Shares Outstanding, provided that if
such readjustment is an increase in the Conversion Price, such readjustment
shall not exceed the amount (as adjusted by SECTIONS 5(b)(i) AND 5(b)(iii)) by
which the Conversion Price was decreased pursuant to SECTION 5(b)(iii) upon the
issuance of the Option or Convertible Security. The termination of expiration of
any right to purchase shares of Common under any Option granted prior to the
date hereof or of any right to convert or exchange Convertible Securities issued
prior to the date hereof shall not trigger any adjustment to the Conversion
Price, but the shares of Common issuable under such Options or Convertible
Securities shall no longer be counted in determining the number of Shares
Outstanding on the date hereof for purposes of subsequent calculations under
this SECTION 5(b).

          (viii)   EXCLUDED SECURITIES. Notwithstanding anything herein to the
contrary, the Conversion Price shall not be adjusted pursuant to this SECTION
5(b) by virtue of the issuance and/or sale of "Excluded Securities", which means
the following: (a) up to 682,185 shares of Common, Options or Convertible
Securities to be issued and/or sold to employees, advisors (including, without
limitation, financial, technical and legal advisers), directors or officers of,
or consultants to, the Company or any of its subsidiaries pursuant to a stock
grant, stock option plan, stock purchase plan, pension or profit sharing plan or
other stock

<Page>

agreement or arrangement existing as of the date hereof and which has been
approved by the stockholders of the Company; (b) the reissuance of any expired
and unexercised, cancelled or forfeited Options under any plan referred to in
SUBSECTION (a) above; (c) the issuance of shares of Common, Options and/or
Convertible Securities pursuant to Options and Convertible Securities
outstanding as of the date hereof; (d) the issuance of shares of Common, Options
or Convertible Securities as a stock dividend or upon any subdivision or
combination of shares of Common or Convertible Securities; (e) the issuance of
shares of Common pursuant to the exercise of certain warrants to be issued in
connection with the issuance of the shares of Series A Preferred; or (f) shares
of Common or Convertible Securities issued and sold by and for the account of
the Company pursuant to an effective registration statement filed by the Company
pursuant to the Securities and Exchange Act of 1934, as amended. For all
purposes of this SECTION 5(b), all shares of Common which are Excluded
Securities shall be deemed to have been issued for an amount of consideration
per share equal to the Conversion Price in effect at the time of issuance.

          (ix)     All calculations under this SECTION 5(b) shall be made to
the nearest one half of one cent ($.005) or to the nearest one-tenth of a share,
as the case may be.

          (x)      NOTICE OF ADJUSTMENT. Promptly after adjustment of the
Conversion Price, the Company shall give written notice thereof, by first class
mail, postage prepaid, addressed to the registered Holders at the address of
such Holders as shown on the books of the Company. The notice shall be signed by
an officer of the Company and shall state the effective date of the adjustment
and the Conversion Price resulting from such adjustment, setting forth in
reasonable detail the method of calculation and the facts upon which such
calculation is based.

     (c) MECHANICS OF CONVERSION. Conversion of the Series A Preferred to Common
may be exercised in whole or in part by a Holder telecopying an executed and
completed notice of conversion ("Notice of Conversion") to the transfer agent of
the Company (the "Transfer Agent"), with a copy to the Company, and delivering
the original Notice of Conversion and the certificate representing the shares of
Series A Preferred to the Transfer Agent by hand or by express courier within
three (3) business days of exercise. Each date on which a Notice of Conversion
is telecopied to the Transfer Agent in accordance with the provisions hereof
shall be deemed a "Conversion Date." The Transfer Agent will transmit the
certificates representing the Common issuable upon conversion of all or any part
of the shares of Series A Preferred (together with any certificates for
replacement shares of Series A Preferred not previously converted but included
in the original certificate presented for conversion) to the Holder via express
courier within three (3) business days after the Transfer Agent has received the
original Notice of Conversion and certificate for the shares of Series A
Preferred being so converted. The Notice of Conversion and certificate
representing the portion of the shares of Series A Preferred converted shall be
delivered as follows:

                   To the Transfer Agent:

                   First City Transfer Company
                   111 Wood Avenue South, Suite 206
                   Iselin, NJ 08830
                   Attn.: Ms. Kathy Zaleski

<Page>

                   (Tel) (908)205-4517
                   (Fax) (908)205-4544

                   To the Company:

                   KTI, Inc.
                   7000 Boulevard East
                   Guttenberg, NJ 07093
                   Attn.: President
                   (Tel)  201-854-7777
                   (Fax)  201-854-1771

or to such other person at such other place as the Company shall designate to
the Holder in writing. The Company shall immediately notify each Holder of any
change of Transfer Agent for the Company or termination of the existing Transfer
Agent. If there is no Transfer Agent at any time, all references in this SECTION
5(c) to "Transfer Agent" shall be deemed to refer to the Company.

          (i)      NO FRACTIONAL SHARES. No fractional shares shall be issued
upon the conversion of the Series A Preferred. The Company shall pay to any
Holder who has converted all or any portion of the shares of Series A Preferred
cash in an amount equal to any fractional shares, such amount of cash to be
determined by multiplying the closing trading price on the last trading day
prior to the date of the conversion by the amount of the fractional share.

     (d)  LOST OR STOLEN CERTIFICATES. Upon receipt by the Company of evidence
of the loss, theft, destruction or mutilation of any certificates representing
shares of Series A Preferred, and (in the case of loss, theft or destruction) of
indemnity or security reasonably satisfactory to the Company, and upon surrender
and cancellation of the certificate(s), if mutilated, the Company shall execute
and deliver new certificate(s) of like tenor and date. However, Company shall
not be obligated to re-issue such lost or stolen certificates if Holder
contemporaneously requests Company to convert such Series A Preferred into
Common.

     (e)  MANDATORY CONVERSION. The Series A Preferred is subject to mandatory
conversion, at which time all shares of Series A Preferred will automatically be
converted at the Conversion Price, (i) upon the completion of a firm
underwritten public offering of Common by the Company (a "Public Offering") in
which (a) gross proceeds to the Company, before expenses and underwriters'
discounts and commissions, of at least $20,000,000 are received, (b) the Common
so offered is sold at an offering price per share to the public of at least 200%
of the Conversion Price then in effect, and (c) the Holders receive, as a
consequence of participation in such Public Offering, net proceeds equal to or
greater than $3,900,000 (a Public Offering which meets the conditions set forth
in (a), (b) and (c) above being referred to as a "Qualified Public Offering"),
or (ii) immediately following the completion of a Public Offering that is not a
Qualified Public Offering, but, (a) in which the Company receives gross
proceeds, before expenses and underwriters' discounts and commissions, of at
least $20,000,000, and (b) upon the "Market Price" (as defined below) for each
share of Common exceeding 200% of the Conversion Price then in effect for twenty
(20) consecutive trading days, and the average daily trading volume of the
Common

<Page>

for such twenty (20) consecutive day period exceeding 10,000 shares. "Market
Price" shall mean the closing bid price for the Common, as reported by the
Nasdaq National Market System ("Nasdaq"), or if the Common is not traded on
Nasdaq, the closing price or, if not available, the low price of the Common in
the over-the-counter market or the principal national securities exchange on
which the Common is traded.

     (f)  RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The Company shall at
all times reserve and keep available out of its authorized but unissued shares
of Common such number of its shares of Common as shall from time to time be
sufficient to effect the conversion of all then outstanding shares of Series A
Preferred. The Company covenants and agrees that if at any time it would be
unable to fully convert all shares of Series A Preferred then outstanding, it
will promptly use its best efforts to obtain stockholder approval, within 135
days thereafter, to amend its Certificate of Incorporation to increase the
number of authorized shares of Common by an amount sufficient to permit the
conversion of all shares of Series A Preferred then outstanding.

     (g)  REDEMPTION BY COMPANY.

          (i)      REDEMPTION DATE. The Company shall redeem all outstanding
shares of the Series A Preferred on the fifth anniversary of the date of the
issuance of the shares of Series A Preferred (the "Redemption Date").

          (ii)     REDEMPTION PRICE. The redemption price per share of Series A
Preferred shall equal $12.00 per share of Series A Preferred (to be adjusted
proportionately if the shares of Series A Preferred to which such amount is
applicable are subdivided into a greater number or combined into a lesser
number).

          (iii)    MECHANICS OF REDEMPTION. The Company shall effect each such
redemption by giving notice thereof ("Redemption Notice"), by facsimile, by
5 P.M. New York City time no later than the tenth (10th) business day prior to
the Redemption Date and shall provide a copy of such redemption notice by
overnight or 2-day courier, to each Holder and the Company's transfer agent for
the Series A Preferred ("Series A Transfer Agent"). Such redemption notice shall
indicate the applicable redemption price and whether the Company has elected, at
its option, to redeem the shares of Series A Preferred for cash (a "Cash
Redemption") or for Common (a "Redemption for Stock"). In the event of a
Redemption for Stock, the Company shall also specify in the Redemption Notice
the number of shares of Common to be issued to the Holder, which shall be based
on the following formula:

      Number of shares issued upon redemption of one (1) share of Series A
                                   Preferred =

                                Redemption Price
                          -----------------------------
                            Adjusted Conversion Price

where, the "Adjusted Conversion Price" shall equal ninety five percent (95%) of
the average closing bid price of the Common as reported by Nasdaq for the
previous ten (10) business days ending on the day before the Redemption Date.

<Page>

          (iv)     HOLDER'S CONVERSION RIGHTS. Notwithstanding the foregoing,
Holder shall have five business days following receipt of the Redemption Notice
from the Company to elect, in its sole discretion, to convert all or part of the
Series A Preferred otherwise being redeemed. Such conversion shall be effected
in accordance with the provisions of SECTION 5 hereof, and if an appropriate
Notice of Conversion is delivered to the Company in a timely manner, such shares
of Series A Preferred shall be deemed to be converted and not redeemed.

          (v)      OPTIONAL REDEMPTION. Upon a "Change of Control Transaction"
(as defined herein), the Company shall redeem, at the option of the Holder, upon
receipt of a written redemption request from such Holder, the Series A Preferred
for the accreted value of the shares of Series A Preferred, which shall be the
initial purchase price of $8 per share plus interest of 8.19 percent per annum
calculated based on the number of actual days elapsed in a 365 day year or 366
day year, as appropriate, plus any dividends which have been declared and which
the Holders are entitled to receive with respect to each share of Series A
Preferred. A "Change of Control Transaction," is defined as any merger,
consolidation or reorganization of the Company pursuant to which shares of
capital stock of the Company are converted into cash, securities or other
property in which the holders of a majority of the voting capital stock of the
Company (on an as-converted and exercised basis) immediately prior thereto
beneficially own, directly or indirectly, less than 50% of the combined voting
power of the capital stock of the company surviving or resulting from such
merger, consolidation or reorganization.

          (vi)     PAYMENT OF REDEMPTION PRICE OR ISSUANCE OF SHARE
CERTIFICATES. Upon receipt of a Redemption Notice, Holder shall send its shares
of Series A Preferred being redeemed to the Company or its Series A Transfer
Agent, and the Company shall pay the applicable redemption price within three
(3) business days of receipt of the shares of Series A Preferred, if a Cash
Redemption, or issue certificates representing shares of Common, if a Redemption
for Stock. The Company shall not be obligated to deliver the redemption price or
shares of Common, as the case may be, unless the shares of Series A Preferred so
redeemed are delivered to the Company or its Series A Transfer Agent, or, in the
event one or more certificates have been lost, stolen, mutilated or destroyed,
Holder delivers to the Company a lost certificate affidavit and indemnification
agreement reasonably satisfactory to the Company and the Series A Transfer
Agent. Any redemption payment owed to any Holder under this SECTION 5(g) which
is not paid when due shall bear interest at a rate of 4% in excess of the prime
rate of interest in effect as announced by KeyBank of New York.

     Section 6.    VOTING RIGHTS. The Holder of each outstanding share of Series
A Preferred shall have the right to one vote for each share of Common into which
each such share of Series A Preferred could then be converted (assuming, for
this purpose only, that shares of Series A Preferred are convertible into
fractional shares) at the record date for the determination of stockholders
entitled to vote on such matters or, if no such record date is established, at
the date of such vote is taken or any written consent of stockholders is
solicited. With respect to such vote, such Holder shall have fall voting rights
and powers equal to the voting rights and powers of the holders of shares of
Common, shall be entitled to notice of any stockholders' meeting in accordance
with the By-Laws of the Company, and shall be entitled to vote, together with
holders of shares of Common, with respect to any question upon which
stockholders of the Company have the right to vote. With respect to all

matters upon which stockholders of the Company are entitled to vote, the holders
of outstanding shares of Common and the Holders of all outstanding shares of
Series A Preferred shall vote together without regard to class, except as
expressly required herein, by the Certificate of Incorporation and the By-Laws
of the Company or the Business Corporation Law of the State of New Jersey.

     Section 7.    STATUS OF CONVERTED STOCK. If any shares of Series A
Preferred shall be converted pursuant to SECTION 5 above, the shares so
converted shall be canceled, shall return to the status of authorized but
unissued Preferred Stock of no designated series, and shall not be issuable by
the Company as Series A Preferred.

     Section 8.    PROTECTIVE PROVISION. So long as shares of Series A Preferred
are outstanding, the Company shall not without first obtaining the approval (by
vote or written consent, as provided by the applicable laws of the State of New
Jersey) of the Holders of at least a majority of the then outstanding shares of
Series A Preferred:

     (a)  alter or change the rights, preferences or privileges of the Series A
Preferred so as to affect adversely the Series A Preferred;

     (b)  increase the size of the authorized number of Series A Preferred; or

     (c)  do any act or thing not authorized or contemplated by this Certificate
of Designation which would result in taxation of the Holders of shares of the
Series A Preferred under Section 305 of the Internal Revenue Code of 1986, as
amended (or any comparable provision of the Internal Revenue Code as hereafter
from time to time amended).

     If Holders of at least a majority of the then outstanding shares of Series
A Preferred agree to allow the Company to alter or change the rights,
preferences or privileges of the shares of Series A Preferred, pursuant to
SUBSECTION 8(a) above, so as to affect the Series A Preferred, then the Company
will promptly deliver notice of such approved change to the Holders that did not
agree to such alteration or change."

     3.   Such resolution was duly adopted by the Board of Directors of the
Corporation on May 28, 1997.

     4.   The Restated Certificate of Incorporation, as amended, is amended so
that the designation and number of shares of each class and series acted upon in
the resolution, and the relative rights, preferences and limitations of each
such class and series, are as stated in the resolution.

     IN WITNESS WHEREOF, the Corporation has caused this Certificate of
Amendment to be executed on its behalf this 30th day of May, 1997.

                                  OF KTI, INC.

          Pursuant to the provisions of Sections 14A:7-2(4) and l4A:9-2(2),
Corporations, General, of the New Jersey Statutes, the undersigned Corporation
executes the following Certificate of Amendment to its Restated Certificate of
Incorporation:

          1.   The name of the corporation is KTI, Inc. (the "Corporation").

          2.   The following resolution was adopted by the Board of Directors of
the Corporation:

          Resolved that a new ARTICLE ELEVENTH relating to the designation,
number rights, preferences and limitation of a series of preferred stock shall
be added to the Restated Certificate of Incorporation, as amended, and shall
read in its entirety as follows:

                               "ARTICLE ELEVENTH"

          Section 1.    DESIGNATION AND AMOUNT. There is hereby created out of
the authorized and unissued shares of preferred stock of the Corporation a
series of preferred stock, no par value, designated as the "8 3/4% Series B
Convertible Exchangeable Preferred Stock" (the "Series B Preferred"). The number
of shares constituting such series shall be 880,000. The liquidation preference
of the Series B Preferred (the "Liquidation Preference") shall be $25.00 per
share.

          Section 2.    RANK. The Series B Preferred shall, with respect to
dividend distributions and distributions upon the liquidation, winding-up and
dissolution of the Corporation, rank (i) senior to all classes of Common Stock
of the Corporation and to each other class of capital stock or series of
preferred stock established after the Series B Preferred Issue Date by the Board
of Directors, the terms of which do not expressly provide that it ranks senior
to or on a parity with the Series B Preferred as to dividend distributions and
distributions upon the liquidation, winding-up and dissolution of the
Corporation (collectively referred to with the Common Stock of the Corporation
as "Junior Securities"); (ii) on a parity with the Corporation's Series A
Preferred Stock and, subject to certain conditions, with any class of capital
stock or series of preferred stock issued by the Corporation which was
established after the Series B Preferred Issue Date by the Board of Directors,
the terms of which expressly provide that such class or series will rank on a
parity with Series B Preferred as to dividend distributions and distributions
upon the liquidation, winding-up and dissolution of the Corporation
(collectively referred to as "Parity Securities"); and (iii) subject to certain
conditions, junior to

287281                                                                0100279875
534830

<Page>

each class of capital stock or series of preferred stock issued by the
Corporation which was established after the Series B Preferred Issue Date by the
Board of Directors, the terms of which expressly provide that such class or
series will rank senior to the Series B Preferred as to dividend distributions
and distributions upon liquidation, winding-up and dissolution of the
Corporation (collectively referred to as "Senior Securities"). The Series B
Preferred shall be subject to the issuance of series of Junior Securities,
Parity Securities and Senior Securities, provided that the Corporation may not
issue any new class of Parity Securities or Senior Securities without the
approval of the Holders of at lease a majority of the shares of Series B
Preferred then outstanding, voting or consenting, as the case may be, together
as one class unless the PRO FORMA ratios for the latest twelve months of (i) net
income available for preferred dividends to preferred dividends is not less than
1:1 and (ii) EBITDA less capital expenditures, securities amortization and
redemption, cash taxes and changes in working capital to preferred dividends is
not less than 1:2:1. The Series B Preferred shall rank junior in right of
payment to all indebtedness and other debt obligations of the Corporation.

          Section 3.    DIVIDENDS.

               (a)  Beginning on the Series B Preferred Issue Date, the Holders
     of the outstanding shares of Series B Preferred shall be entitled to
     receive, when, as and if declared by the Board of Directors, from any
     source of funds legally available therefor, distribution in the form of
     cash dividends on each share of Series B Preferred, at a rate PER ANNUM
     equal to 8 3/4% of the Liquidation Preference per share of the Series B
     Preferred plus accumulated and unpaid dividends thereon as of the last
     Dividend Payment Date, payable quarterly; provided that if the Corporation
     fails to register the Series B Preferred pursuant to the terms of, and
     within the time periods set forth in, the Registration Rights Agreement
     dated August 7, 1997 between the Corporation and credit Research & Trading
     LLC, then the dividend rate shall increase 0.5% per annum for each period
     during which such registration is not effective. All dividends shall be
     cumulative, whether or not earned or declared, on a daily basis from the
     Series B Preferred Issue Date and shall be payable quarterly in arrears on
     each Dividend Payment Date, commencing on November 1, 1997. Each
     distribution in the form of a dividend shall be payable to the Holders of
     record as they appear on the stock register of the Corporation on the
     record date for such purpose fixed by the Board of Directors, which shall
     not be less than 10 nor more than 60 days preceding the related Dividend
     Payment Date. Dividends shall cease to accumulate in respect of shares of
     the Series B Preferred on the Exchange Date or on the date of their earlier
     redemption unless the Company shall have failed to issue the appropriate
     aggregate principal amount of Exchange Notes in respect of the Series

                                       -2-
<Page>

     B Preferred on the Exchange Date or shall have failed to pay the relevant
     redemption price on the date fixed for redemption.

               (b)  Nothing herein contained shall in any way or under any
     circumstances be construed or deemed to require the Board of Directors to
     declare, or the Corporation to pay or set apart for payment, any cash
     dividends on shares of the Series B Preferred at any time.

               (c)  Dividends on account of arrears for any past Dividend Period
     and dividends in connection with any optional redemption pursuant to
     Section 6(a) may be declared and paid at any time, without reference to any
     regular Dividend Payment Date, to Holders of record on such date, not more
     than 45 days prior to the payment thereof, as may be fixed by the Board of
     Directors.

               (d)  Except as set forth in the following sentence, no dividends
     shall be declared by the Board of Directors or paid or funds set apart for
     the payment of dividends by the Corporation on any Parity Securities for
     any period unless full cumulative dividends shall have been or
     contemporaneously are declared and paid in cash or declared and a sum in
     cash set apart sufficient for such payment of the Series B Preferred for
     all Dividend Periods terminating on or prior to the date of payment of such
     dividends on such Parity Securities. If full dividends in cash are not so
     paid upon the shares of the Series B Preferred and any other Parity
     Securities, all dividends declared upon the Series B Preferred and other
     Parity Securities shall be declared PRO RATA so that the amount of
     dividends declared on each class or series of the Series B Preferred and
     such Parity Securities shall in all cases bear to each other the same ratio
     that the aggregate accumulated dividends on the Series B Preferred and such
     Parity Securities bear to each other.

               (e)  (i)      Holders of shares of the Series B Preferred shall
     be entitled to receive the dividends provided for in Section 3(a) hereof
     in preference to and in priority over any dividends upon any of the Junior
     Securities.

                    (ii)     So long as any shares of Series B preferred are
          outstanding, the Corporation shall not declare, pay or set apart for
          payment any dividend on any Junior Securities or make any payment on
          account of, or set apart for payment money for a sinking or other
          similar fund for, the purchase, redemption or other retirement of, any
          Junior Securities or any warrants, rights, calls or options
          exercisable for or convertible into any Junior Securities, or make any
          distribution in respect thereof, either directly or

                                       -3-
<Page>

          indirectly, and whether in cash, obligations or shares of the
          Corporation or other property (other than distributions or dividends
          in Junior Securities to the holders of Junior Securities), and shall
          not permit any corporation or other entity directly or indirectly
          controlled by the Corporation to purchase or redeem any Junior
          Securities or any such warrants, rights, calls or options unless full
          cumulative dividends determined in accordance herewith have been paid
          or deemed paid in full on the Series B Preferred for all past Dividend
          Periods.

                    (iii)    So long as any shares of the Series B Preferred are
          outstanding, the Corporation shall not make any payment on account of,
          or set apart for payment money for a sinking or other similar fund
          for, the purchase, redemption or other retirement of, any Parity
          Securities or any warrants, rights, calls or options exercisable for
          or convertible into any Parity Securities, and shall not permit any
          corporation or other entity directly or indirectly controlled by the
          Corporation to purchase or redeem any Parity Securities or any such
          warrants, rights, calls or options unless the dividends determined in
          accordance herewith on the Series B Preferred have been paid or
          deemed paid in full for all past Dividend Periods.

               (f)  Dividends payable on shares of the Series B Preferred for
     any period of less than a year shall be computed on the basis of a 360-day
     year of twelve 30-day months and the actual number of days elapsed in any
     period of less than one month. If any Dividend Payment Date occurs on a day
     that is not a Business Day, any accumulated dividends otherwise payable on
     such Dividend Payment Date shall be paid on the next succeeding Business
     Day.

          Section 4.    LIQUIDATION PREFERENCE.

               (a)  Upon any voluntary or involuntary dissolution or winding-up
     of the Corporation, the Holders of shares of Series B Preferred then
     outstanding shall be entitled to be paid, out of the assets of the
     Corporation available for distribution, the Liquidation Preference, plus an
     amount in cash equal to accumulated and unpaid dividends thereon as of the
     last Dividend Payment Date prior to the date fixed for dissolution or
     winding-up (including an amount in cash equal to a prorated dividend for
     the period from the last Dividend Payment Date to the date fixed for
     liquidation, dissolution or winding-up), before any payment shall be made
     or any assets distributed to the holders of any Junior Securities,
     including, without limitation, Common Stock of the Corporation. If, upon
     any voluntary or involuntary liquidation, dissolution or winding-up of the
     Corporation, the amount payable with respect to the Series B Preferred

                                       -4-
<Page>

     and all other Parity Securities is not paid in full, then the Holders of
     the Series B Preferred and the Parity Securities shall share equally and
     ratably in any distribution of assets of the Corporation in proportion to
     the full Liquidation Preference and accumulated and unpaid dividends
     thereon as of the last Dividend Payment Date prior to the date of such
     voluntary or involuntary dissolution or winding-up, to which each is
     entitled. After payment of the full amount of the Liquidation Preferences
     and accumulated and unpaid dividends thereon as of the last Dividend
     Payment Date to which they are entitled, the Holders of shares of Series B
     Preferred shall not be entitled to any further participation in any
     distribution of assets of the Corporation.

               (b)  For the purposes of this Section 4 only, neither the sale,
     lease, conveyance, exchange or transfer (for cash, shares of stock;
     securities or other consideration) of all or substantially all of the
     property or assets of the Corporation nor the consolidation or merger of
     the Corporation with or into one or more entities shall be deemed to be a
     liquidation, dissolution or winding-up of the Corporation.

          Section 5.    CONVERSION.

               (a)  A Holder of shares of Series B Preferred may convert such
     shares into Common Stock at any time. For the purposes of conversion, each
     share of Series B Preferred shall be valued at the Liquidation Preference
     plus accumulated and unpaid dividends thereon as of the last Dividend
     Payment Date, which shall be divided by the Conversion Price in effect on
     the Conversion Date to determine the number of shares issuable upon
     conversion, except that the right to convert shares of Series B Preferred
     called for redemption shall terminate at the close of business on the
     Business Day preceding the Redemption Date and shall cease if not exercised
     prior to that time (unless the Corporation shall default in making the
     payment due upon redemption). Immediately following such conversion, the
     rights of the Holders of converted Series B Preferred shall cease and the
     persons entitled to receive the Common Stock upon the conversion of Series
     B Preferred shall be treated for all purposes as having become the owners
     of such Common Stock.

               (b)  To convert Series B Preferred, a Holder must (i) surrender
     the certificate or certificates evidencing the shares of Series B Preferred
     to be converted, duly endorsed in a form satisfactory to the Corporation,
     at the office of the Corporation or the Corporation's transfer agent for
     the Series B Preferred, (ii) notify the Corporation at such office that he
     elects to convert Series B Preferred and the number of shares he wishes to
     convert, (iii) state in

                                       -5-
<Page>

     writing the name or names in which he wishes the certificate or
     certificates for shares of Common Stock to be issued, and (iv) pay any
     transfer or similar tax if required. In the event that a Holder fails to
     notify the Corporation of the number of shares of Series B Preferred which
     he wishes to convert, he shall be deemed to have elected to convert all
     shares represented by the certificate or certificates surrendered for
     conversion. The date on which the Holder satisfies all those requirements
     is the "Conversion Date." As soon as practical, the Corporation shall
     deliver a certificate for the number of full shares of Common Stock
     issuable upon the conversion, a payment in cash for any factional share and
     a new certificate representing the unconverted portion, if any, of the
     shares of Series B Preferred represented by the certificate or certificates
     surrendered for conversion. The person in whose name the Common Stock
     certificate is registered shall be treated as the shareholder of record on
     and after the Conversion Date. No payment or adjustment will be made for
     accumulated and unpaid dividends on converted shares of Series B Preferred
     or for dividends on any Common stock issued upon such conversion. A share
     of Series B Preferred surrendered for conversion during the period from the
     close of business on any record date for the payment of dividends to the
     opening of business of the corresponding Dividend Payment Date must be
     accompanied by a payment in cash in an amount equal to the dividend payable
     on such Dividend Payment Date, unless such share of Series B Preferred has
     been called for redemption on a Redemption Date occurring during the period
     from the close of business on any record date for the payment of dividends
     to the close of business on the Business Day immediately following the
     corresponding Dividend Payment Date. The dividend payment with respect to a
     share of Series B Preferred called for redemption on a date during the
     period from the close of business on any record date for the payment of
     dividends to the close of business on the Business Day immediately
     following the corresponding Dividend Payment Date will be payable on such
     Dividend Payment Date to the record Holder of such share on such record
     date, notwithstanding the conversion of such share after such record date
     and prior to such Dividend Payment Date, and the Holder converting such
     share of Series B Preferred need not include a payment of such dividend
     amount upon surrender of such share of Series B Preferred for conversion.
     If a Holder of Series B Preferred converts more than one share at a time,
     the number of full shares of Common Stock issuable upon conversion shall be
     based on the total value of all shares of Series B Preferred converted. If
     the last day on which Series B Preferred may be converted is not a Business
     Day, Series B Preferred may be surrendered for conversion on the next
     succeeding Business Day.

               (c)  The Corporation shall not issue a fractional share of Common
     Stock upon conversion of Series B Preferred.

                                       -6-
<Page>

     Instead the Corporation shall pay a cash adjustment for the current market
     value of the fractional share. The current market value of a fraction of a
     share shall be determined as follows: Multiply the current market price of
     a full share by the fraction. Round the result to the nearest cent. The
     current market price of a share of Common Stock is the Closing Price of the
     Common Stock on the last Trading Day prior to the Conversion Date.

               (d)  If a Holder converts shares of Series B Preferred, the
     Corporation shall pay any documentary, stamp or similar issue or transfer
     tax due on the issue of shares of Common Stock upon the conversion.
     However, the Holder shall pay any such tax that is due because the shares
     are issued in a name other than the Holder's name.

               (e)  The Corporation has reserved and shall continue to reserve
     out of its authorized but unissued Common Stock or its Common Stock held in
     treasury enough shares of Common Stock to permit the conversion of the
     Series B Preferred in full. All shares of Common Stock that may be issued
     upon conversion of Series B Preferred shall be fully paid and
     nonassessable. The Corporation shall endeavor to comply with all securities
     laws regulating the offer and delivery of shares of Common Stock upon
     conversion of Series B Preferred and shall endeavor to list such shares on
     each national securities exchange on which the Common Stock is listed.

               (f)  In case the Corporation shall pay or make a dividend or
     other distribution on any class of capital stock of the Corporation in
     Common Stock, the Conversion Price in effect at the opening of business on
     the day following the date fixed for the determination of shareholders
     entitled to receive such dividend or other distribution shall be reduced by
     multiplying such Conversion Price by a fraction the numerator of which
     shall be the number of shares of Common Stock outstanding at the close of
     business on the date fixed for such determination and the denominator of
     which shall be the sum of such number of shares and the total number shares
     constituting such dividend or other distribution, such reduction to become
     effective immediately after the opening of business on the day following
     the date fixed for such determination of the holders entitled to such
     dividends and distributions. For the purposes of this section 5(f), the
     number of shares of Common Stock at any time outstanding shall not include
     shares held in the treasury of the Corporation. The Corporation will not
     pay any dividend or make any distribution on shares of Common Stock held in
     the treasury of the Corporation.

               (g)  In case the Corporation shall issue rights, options or
     warrants to all holders of its Common stock entitling them to subscribe
     for, purchase or acquire shares

                                       -7-
<Page>

     of Common Stock at a price per share less than the current market price per
     share (determined as provided in Section 5(k) below) of Common Stock on
     the date fixed for the determination of shareholders entitled to receive
     such rights, options or warrants, the Conversion Price in effect at the
     opening of business on the day following the date fixed for such
     determination shall be reduced by multiplying such Conversion Price by a
     fraction the numerator of which shall be the number of shares of Common
     Stock outstanding at the close of business on the date fixed for such
     determination plus the number of shares of Common Stock which the aggregate
     of the offering price of the total number of shares of Common Stock so
     offered for subscription, purchase or acquisition would purchase at such
     current market price and the denominator of which shall be the number of
     shares of Common Stock outstanding at the close of business on the date
     fixed for such determination plus the number of shares of Common stock so
     offered for subscription, purchase or acquisition, such reduction to become
     effective immediately after the opening of business on the day following
     the date fixed for such determination of the holders entitled to such
     rights, options or warrants. However, upon the expiration of any right,
     option or warrant to purchase Common Stock, the issuance of which resulted
     in an adjustment in the Conversion Price pursuant to this Section 5(g), if
     any such right, option or warrant shall expire and shall not have been
     exercised, the Conversion Price shall be recomputed immediately upon such
     expiration and effectively immediately upon such expiration shall be
     increased to the price it would have been (but reflecting any other
     adjustments to the Conversion Price made pursuant to the provisions of this
     Section 5 after the issuance of such rights, options or warrants) had the
     adjustment of the Conversion Price made upon the issuance of such rights,
     options or warrants been made on the basis of offering for subscription or
     purchase only that number of shares of Common Stock actually purchased upon
     the exercise of such rights, options or warrants. No further adjustment
     shall be made upon exercise of any right, option or warrant if any
     adjustment shall have been made upon the issuance of such security. For the
     purposes of this Section 5(g), the number of shares of Common Stock at any
     time outstanding shall not include shares held in the treasury of the
     Corporation. The Corporation will not issue any rights, options or warrants
     in respect of shares of Common Stock held in the treasury of the
     Corporation.

               (h)  In case the outstanding shares of Common stock shall be
     subdivided into a greater number of shares of Common Stock, the Conversion
     Price in effect at the opening of business on the day following the day
     upon which such subdivision becomes effective shall be reduced, and,
     conversely, in case the outstanding shares of Common Stock shall each be
     combined into a smaller number of shares of

                                       -8-
<Page>

     Common Stock, the Conversion Price in effect at the opening of business on
     the day following the day upon which such combination becomes effective
     shall be increased to equal the product of the Conversion Price in effect
     on such date and a fraction the numerator of which shall be the number of
     shares of Common Stock outstanding immediately prior to such subdivision or
     combination, as the case may be, and the denominator of which shall be the
     number of shares of Common Stock outstanding immediately after such
     subdivision or combination, as the case may be. Such reduction or increase,
     as the case may be, shall become effective immediately after the opening of
     business on the day following the date upon which such subdivision or
     combination becomes effective.

               (i)  In case the Corporation shall, by dividend or otherwise,
     distribute to all holders of its Common Stock (i) evidences of its
     indebtedness or (ii) shares of any class of capital stock, cash or other
     assets (including securities, but excluding (A) any rights, options or
     warrants referred to in Section 5(g) above, (B) any dividend or
     distribution referred to in Section 5(f) above and (C) cash dividends paid
     from the Corporation's retained earnings, unless the sum of (1) all such
     cash dividends and distributions made within the preceding 12 months in
     respect of which no adjustment has been made and (2) any cash and the fair
     market value of other consideration paid in respect of any repurchases of
     Common Stock by the Corporation or any of its subsidiaries within the
     preceding 12 months in respect of which no adjustment has been made,
     exceeds 20% of the Corporation's market capitalization (being the product
     of the then current market price per share (determined as provided in 5(k)
     below) of the Common Stock times the aggregate number of shares of Common
     Stock then outstanding) on the record date for such distribution, then in
     each case, the Conversion Price in effect at the opening of business on the
     day following the date fixed for the determination of holders of Common
     Stock entitled to receive such distribution shall be adjusted by
     multiplying such Conversion Price by a fraction of which the numerator
     shall be the current market price per share (determined as provided Section
     5(k) below) of the Common Stock on such date of determination (or, if
     earlier, on the date on which the Common Stock goes "ex-dividend" in
     respect of such distribution) less the then fair market value as determined
     by the Board of Directors (whose determination shall be conclusive and
     shall be described in a statement which shall be available upon request) of
     the portion of the capital stock, cash or other assets or evidences of
     indebtedness so distributed (and for which an adjustment to the Conversion
     Price has not previously been made pursuant to the terms of this Section 5)
     applicable to one share of Common Stock, and the denominator shall be such
     current market price per share of the Common Stock, such adjustment to
     become effective

                                       -9-
<Page>

     immediately after the opening of business on the day following such date of
     determination of the holders entitled to such distribution. The following
     transactions shall be excluded from the foregoing clauses (1) and (2): (I)
     repurchases of Common Stock issued under the Corporation's stock incentive
     programs and (II) dividends or distributions payable-in-kind in additional
     shares of, or warrants, rights, calls or options exercisable for or
     convertible into additional shares of Junior Securities.

               (j)  The reclassification or change of Common Stock into
     securities, including securities other than Common Stock, (other than any
     reclassification upon a consolidation or merger to which Section 5(r) below
     shall apply) shall be deemed to involve (i) a distribution of such
     securities other than Common Stock to all holders of Common Stock (and the
     effective date of such reclassification shall be deemed to be "the date
     fixed for the determination of holders of Common Stock entitled to receive
     such distribution" within the meaning of Section 5(i) above), and (ii) a
     subdivision or combination, as the case may be, of the number of shares of
     Common Stock outstanding immediately prior to such reclassification into
     the number of shares of Common Stock outstanding immediately thereafter
     (and the effective date of such reclassification shall be deemed to be "the
     day upon which such subdivision becomes effective" or "the day upon which
     such combination becomes effective," as the case may be, and "the day upon
     which such subdivision or combination becomes effective" within the meaning
     of Section 5(h) above).

               (k)  For the purpose of any computation under Section (g) or (i)
     above, the current market price per share of Common Stock on any day shall
     be deemed to be the average of the Closing Prices of the Common Stock for
     the 10 consecutive Trading Days preceding such day.

               (l)  No adjustment in the Conversion Price need be made until all
     cumulative adjustments amount to 1% or more of the Conversion Price as last
     adjusted. Any adjustments that are not made shall be carried forward and
     taken into account in any subsequent adjustment. All calculations under
     this Section 5 shall be made to the nearest cent or to the nearest l/100th
     of a share, as the case may be.

               (m)  For purposes of this Section 5, "Common Stock" includes any
     stock of any class of the Corporation which has no preference in respect of
     dividends or of amounts payable the event of any voluntary or involuntary
     liquidation, dissolution or winding-up of the Corporation and which is not
     subject to redemption by the Corporation. However, subject to the
     provisions of Section 5(r) below, shares issuable on conversion of shares
     of Series B Preferred shall include only shares of the class designated

                                      -10-
<Page>

     as Common Stock of the Corporation on the Series B Preferred Issue Date or
     shares of any class or classes resulting from any reclassification thereof
     and which have no preferences in respect of dividends or amounts payable in
     the event of any voluntary or involuntary liquidation, dissolution or
     winding-up of the Corporation and which are not subject to redemption by
     the Corporation; PROVIDED that, if at any time there shall be more than one
     such resulting class, the shares of each such class then so issuable shall
     be substantially in the proportion which the total number of shares of such
     class resulting from all such reclassifications bears to the total number
     of shares of all such classes resulting from all such reclassifications.

               (n)  No adjustment in the Conversion Price shall reduce the
     Conversion Price below the then par value of the Common Stock. No
     adjustment in the Conversion Price need be made under Sections 5(f), (g)
     and (i) above if the Corporation issues or distributes to each Holder of
     Series B preferred the shares of Common Stock, evidences of indebtedness,
     assets, rights, options or warrants referred to in those Sections which
     each Holder would have been entitled to receive had Series B Preferred been
     converted into Common Stock prior to the happening of such event or the
     record date with respect thereto.

               (o)  Whenever the Conversion Price is adjusted, the Corporation
     shall promptly mail to Holders of Series B Preferred, first class, postage
     prepaid, a notice of the adjustment. The Corporation shall file with the
     transfer agent for the Series B Preferred, if any, a certificate from the
     Corporation's independent public accountants briefly stating the facts
     requiring the adjustment and the manner of computing it. Subject to Section
     5(p) below, the certificate shall be conclusive evidence that the
     adjustment is correct.

               (p)  The Corporation from time to time may reduce the Conversion
     Price if it considers such reductions to be advisable in order that any
     event treated for federal income tax purposes as a dividend of stock or
     stock rights will not be taxable to the holders of Common stock by any
     amount, but in no event may the Conversion Price be less than the par value
     of a share of Common Stock. Whenever the Conversion Price is reduced, the
     Corporation shall mail to Holders of Series B Preferred a notice of the
     reduction. The Corporation shall mail, first class, postage prepaid, the
     notice at least 15 days before the date the reduced Conversion Price takes
     effect. The notice shall state the reduced Conversion Price and the period
     it will be in effect. A reduction of the Conversion Price does not change
     or adjust the Conversion Price otherwise in effect for purposes of Sections
     5(f), (g), (h) and (i) above.

                                      -11-
<Page>

               (q)  If:

                    (i)      the Corporation takes any action which would
          require an adjustment in the Conversion Price pursuant to Section 5
          (g), (i) or (j) above;

                    (ii)     the Corporation consolidates or merges with, or
          transfers all or substantially all of its assets to, another
          corporation, and shareholders of the Corporation must approve the
          transaction; or

                    (iii)    there is a dissolution or liquidation of the
          Corporation;

     the Corporation shall mail to Holders of the Series B Preferred, first
     class, postage prepaid, a notice stating the proposed record or effective
     date, as the case may be. The Corporation shall mail the notice at least 10
     days before such date. However, failure to mail the notice or any defect in
     it shall not affect the validity of any transaction referred to in clause
     (i), (ii) or (iii) of this Section 5 (q).

               (r)  In the case of any consolidation of the Corporation or the
     merger of the Corporation with or into any other entity or the sale or
     transfer of all or substantially all of the assets of the Corporation
     pursuant to which the Corporation's Common Stock is converted into other
     securities, cash or assets, upon consummation of such transaction, each
     share of Series B Preferred shall automatically become convertible into the
     kind and amount of securities, cash or other assets receivable upon the
     consolidation, merger, sale or transfer by a holder of the of shares of
     Common Stock into which such share of Series B Preferred might have been
     converted immediately prior to such consolidation, merger, transfer or sale
     (assuming such holder of Common Stock failed to exercise any rights of
     election and received per share the kind and amount receivable per share by
     a plurality of non-electing shares). Appropriate adjustment (as determined
     by the Board of Directors of the Corporation) shall be made in the
     application of the provisions herein set forth with respect to the rights
     and interests thereafter of the Holders of Series B Preferred, to the end
     that the provisions set forth herein (including provisions with respect to
     changes in and other adjustment of the Conversion Price) shall thereafter
     be applicable, as nearly as reasonably may be, in relation to any shares of
     stock or other securities or property thereafter deliverable upon the
     conversion of Series B Preferred. If this Section 5(r) applies, Sections
     5(f), (g), (h), (i) and (j) do not apply.

               (s)  In any case in which this Section 5 shall require that an
     adjustment as a result of any event become

                                      -12-
<Page>

     effective from and after a record date, the Corporation may elect to defer
     until after the occurrence of such event (A) the issuance to the Holder of
     any shares of Series B preferred converted after such record date and
     before the occurrence of such event of the additional shares of Common
     Stock issuable upon such conversion over and above the shares issuable on
     the basis of the Conversion Price in effect immediately prior to adjustment
     and (B) a cash payment for any remaining fractional shares of Common Stock
     as provided in Section 3 (c) above; PROVIDED, HOWEVER, that if such event
     shall not have occurred and authorization of such event shall be rescinded
     by the Corporation, the Conversion Price shall be recomputed immediately
     upon such recision to the price that would have been in effect had such
     event not been authorized, PROVIDED that such recision is permitted by and
     effective under applicable laws.

               (t)  All shares of Series B Preferred converted pursuant to this
     Section 5 shall be restored to the status of authorized and unissued shares
     of preferred stock, without designation as to series and may thereafter be
     reissued as shares of any series of preferred stock.

          Section 6.    REDEMPTION.

               (a)  OPTIONAL REDEMPTION. (i) The Corporation may, at the option
     of the Board of Directors, redeem at any time on or after August 15, 2000,
     from any source of funds legally available therefor, from time to time, in
     whole or in part, in the manner PROVIDED in Section 6(c) hereof, any or
     all of the shares of the Series B Preferred, at the redemption prices set
     forth below if redeemed during the 12 month period beginning on, August 15
     of each of the years indicated below:

<Table>
<Caption>
     YEAR                                        REDEMPTION PRICES
                                               
     2000 ......................................  $26.10 per share
     2001 ......................................  $25.73 per share
     2002 ......................................  $25.37 per share
     2003 ......................................  $25.00 per share
</Table>

     plus, in each case, an amount in cash equal to all accumulated and unpaid
     dividends per share (including an amount in cash equal to a prorated
     dividend for the period from the last Dividend Payment Date to the
     Redemption Date) (the "Optional Redemption Price"), PROVIDED, that no
     optional redemption pursuant to this Section 6(a)(i) shall be authorized or
     made unless prior to giving the applicable Redemption Notice all
     accumulated and unpaid dividends for Dividend Periods ended prior to the
     date of such Redemption Notice shall have been paid in cash.

                                      -13-

                    (ii)     Notwithstanding subsection (i) above, on or after
          August 15, 1999, the Corporation may, at its option, redeem the Series
          B Preferred at $26.47 per share plus accumulated and unpaid dividends
          thereon as of the last Dividend Payment Date if the Common Stock bid
          price has averaged not less than 1.5 times the Conversion Price during
          the preceding 20 consecutive Trading Days.

                    (iii)    In the event of a redemption pursuant to Section
          6(a) (i) or Section(a) (ii) hereof of only a portion of the then
          outstanding shares of the Series B Preferred, the Corporation shall
          effect such redemption PRO RATA according to the number of shares held
          by each Holder of the Series B Preferred or by lot, as may be
          determined by the Corporation in its sole discretion; PROVIDED that
          the Corporation may redeem all shares held by Holders of fewer than
          100 shares of Series B Preferred (or by Holders that would hold fewer
          than 100 shares of Series B Preferred following such redemption) prior
          to its redemption of other shares of Series B Preferred.

               (b)  MANDATORY REDEMPTION. (i) On August 15, 2004, the
     Corporation shall redeem from any source of funds legally available
     therefor, in the manner provided in Section 6 (c), all of the then
     outstanding shares of Series B Preferred at a redemption price equal to
     100% of the then effective Liquidation Preference per share, plus an amount
     equal to all accumulated and unpaid dividends thereon as of the last
     Dividend Payment Date (including an amount in cash equal to a prorated
     dividend for the period from the last Dividend Payment Date to the
     Redemption Date) (the "Mandatory Redemption Price"). The Mandatory
     Redemption Price shall be made at the option of the Corporation either in
     (a) cash or (b) Common Stock valued at 95% of the average Closing Price of
     the Common Stock during the 20 Trading Days prior to such redemption price.

                    (ii)     If the Corporation is unable or shall fail to
          discharge its obligation to redeem all outstanding shares of Series B
          Preferred pursuant to this Section 6(b) (the "Mandatory Redemption
          Obligation"), the Mandatory Redemption Obligation shall be discharged
          as soon as the Corporation is able to discharge such Mandatory
          Redemption Obligation. If and so long as the Mandatory Redemption
          Obligation with respect to the Series B Preferred shall not be fully
          discharged, the Corporation shall not, directly or indirectly, redeem,
          purchase or otherwise acquire any Parity Security or discharge any
          mandatory or optional redemption, sinking fund or other similar
          obligation in respect of any Parity Securities.

               (c)  PROCEDURES FOR REDEMPTION. (i) At least 30 days and not
     more than 60 days prior to the Redemption Date of the Series B Preferred,
     the Corporation shall make a public announcement of the redemption, and
     shall mail written notice (the "Redemption Notice") by first class mail,
     postage prepaid, to each Holder of record on the record date fixed for such
     redemption of the Series B Preferred at such Holder's address as the same
     appears on the stock register of the Corporation, PROVIDED that no failure
     to give such notice nor any deficiency therein shall affect the validity of
     the procedure for the redemption of any shares of Series B Preferred to be
     redeemed except as to the Holder or Holders to whom the Corporation has
     failed to give said notice or except as to the Holder or Holders whose
     notice was defective. The Redemption Notice shall state:

                         (A)  that the redemption is pursuant to Section 6(a)(i)
               or 6(b)(i), as applicable hereof;

                         (B)  the redemption price;

                         (C)  whether all or less than all the outstanding
               shares of the Series B Preferred are to be redeemed and the total
               number of shares of the Series B Preferred being redeemed;

                         (D)  the number of shares of Series B Preferred, held
               as of the appropriate record date, by the Holder that the
               Corporation intends to redeem;

                         (E)  the Redemption Date;

                         (F)  that the Holder is to surrender to the
               Corporation, at the place or places where certificates for shares
               of Series B Preferred are to be surrendered for redemption, in
               the manner and at the price designated, his certificate or
               certificates representing the shares of Series B Preferred to be
               redeemed;

                         (G)  the name of any bank or trust company performing
               the duties referred to in Section 6(c) (iv) hereof; and

                         (H)  that dividends on the shares of the Series B
               Preferred to be redeemed shall cease to accumulate on such
               Redemption Date unless the Corporation defaults in the payment of
               the redemption price,

                    (ii)     Each Holder of Series B Preferred shall surrender
          the certificate or certificates representing such shares of Series B
          Preferred to the Corporation,

                                      -15-
<Page>

          duly endorsed, in the manner and at the place designated in the
          Redemption Notice, and on the Redemption Date the full redemption
          price for such shares shall be payable in cash to the Person whose
          name appears on such certificate or certificates as the owner thereof,
          and each surrendered certificate shall be canceled and retired. In the
          event that less than all of the shares represented by any such
          certificate are redeemed, a new certificate shall be issued
          representing the unredeemed shares.

                    (iii)    Unless the Corporation defaults in the payment in
          full of the applicable redemption price, dividends on the Series B
          Preferred called for redemption shall cease to accumulate on the
          Redemption Date, and the Holders of such redemption shares shall cease
          to have any further rights with respect thereto on the Redemption
          Date, other than the right to receive the redemption price without
          interest.

                    (iv)     If a Redemption Notice shall have been duly given
          or if the Corporation shall have given to the bank or trust company
          hereinafter referred to irrevocable authorization promptly to give
          such notice, and if on or before the Redemption Date specified therein
          an amount in cash equal to the full redemption price shall have been
          segregated and irrevocably deposited by the Corporation with such bank
          or trust company in trust for the pro rata benefit of the Holders of
          the Series B Preferred called for redemption, then, notwithstanding
          that any certificate for shares so called for redemption shall not
          have been surrendered for cancellation, from and after the close of
          business on the day on which such funds are so deposited, all shares
          so called, or to be so called pursuant to such irrevocable
          authorization, for redemption shall no longer be deemed to be
          outstanding and all rights with respect of such shares shall forthwith
          cease and terminate and, for the purposes of Section 6(c)(i) (H) and
          6(c)(iii) above, the Corporation will be deemed to have paid the
          redemption price on the Redemption Date, except only the right of
          Holders thereof to receive from such bank or trust company at any time
          after the time of such deposit the funds so deposited, without
          interest, and the right of the Holders thereof to convert such shares
          as provided in Section 5 hereof to the Business Day preceding the
          Redemption Date. The aforesaid bank or trust company shall be
          organized and in good standing under the laws of the Unites States of
          America or any state thereof, shall have capital, surplus and
          undivided profits aggregating at least $100,000,000 according to its
          last published statement of condition, and shall be identified in the
          Redemption Notice. Any interest

                                      -16-
<Page>

          accrued on such funds shall be paid to the Corporation from time to
          time. Any funds so set aside or deposited, as the case may be, in
          respect of shares of the Series B Preferred that are subsequently
          converted shall be promptly returned to the Corporation. Any funds so
          set aside or deposited, as the case may be, and unclaimed at the end
          of three years from such redemption shall, to the extent permitted by
          law, be released or repaid to the Corporation, after which repayment
          the Holders of the shares so called for redemption shall look only to

                      RESTATED CERTIFICATE OF INCORPORATION
                                  OF KTI, INC.

Corporations, General, of the New Jersey Statutes, the undersigned Corporation
executes the following Certificate of Amendment to its Restated Certificate of
Incorporation:

     1.   The name of the corporation is KTI, Inc. (the "Corporation").

     2.   The following resolution was adopted by the Board of Directors of the
Corporation:

     Resolved that a new ARTICLE TWELFTH relating to the designation, number
rights, preferences and limitations of a series of preferred stock shall be
added to the Restated Certificate of Incorporation, as amended, and shall read
in its entirety as follows:

                                "ARTICLE TWELFTH"

     Section 1.    DESIGNATION AND AMOUNT. The series of Preferred Stock
designated and known as the "Series C Preferred" shall have no par value and the
number of shares constituting the Series C Preferred shall be 447,500. The
Series C Preferred Stock is issued pursuant to the blank check preferred stock
authorized by the Company's Restated Certificate of Incorporation. The Series C
Preferred can only be issued in exchange for Series A Preferred on a one for one
basis. The Series C Preferred Stock shall be redesignated as Series A Preferred
upon all outstanding Series A Preferred being exchanged for Series C Preferred
or converted into Common Stock.

     Section 2.    RANK. The Series C Preferred shall rank: (i) prior to all of
the Company's Common Stock, no par value ("Common"); (ii) PARI PASSU with any
class or series of convertible Preferred Stock, Series A Preferred, Series B
Preferred, or other capital stock of the Company hereafter created, which is
convertible into Common or which, when originally issued, was issued
simultaneously with Common purchase warrants; and (iii) junior to any class of
preferred stock which is not convertible into any other class of securities of
the Company ("Senior Securities"), in each case as to distributions of assets
upon liquidation, dissolution or winding up of the Company, whether voluntary or
involuntary (all such distributions being referred to collectively as
"Distributions").

     Section 3.    DIVIDENDS. If any dividend or other distribution payable in
cash, securities or other property (other than securities of the Company the
issuance of which gives rise to adjustment of the Conversion Price as set forth
below) is declared on the Common, each holder of shares of Series C Preferred on
the record date for such dividend or distribution shall be entitled to receive
on the date of payment or distribution of such dividend or other distribution
the same cash, securities or other property which such holder would have
received on such record date if such holder was the holder of record of the
number (including any fraction) of shares of Common into which the shares of
Series C Preferred then held by such holder are then convertible.

                                                                      0100279875

<Page>

     Section 4.    LIQUIDATION PREFERENCE.

     (a)  In the event of any liquidation, dissolution or winding up of the
Company, either voluntary or involuntary, the holders of Series C Preferred (the
"Holders"), shall be entitled to receive, prior to any payment with respect to
any shares of Common but after any payment with respect to any outstanding
shares of Senior Securities, an amount per share (the "Liquidation Preference")
equal to the sum of (i) $8.00 for each outstanding share of Series C Preferred,
plus (ii) interest of 8.19 percent per annum calculated based on the number of
actual days elapsed in a 365 day year or a 366 day year, as appropriate, from
June 4, 1997, plus (iii) any dividends which have been declared and which the
Holders are entitled to receive with respect to each share of Series C
Preferred. If upon the occurrence of such event, the assets and funds available
to be distributed among the Holders shall be insufficient to permit the payment
to such Holders of the full preferential amounts due to such Holders, then the
entire assets and funds of the Company legally available for distribution to
such Holders and the holders of securities PARI PASSU with the Series C
Preferred shall be distributed among the Holders and holders of such PARI PASSU
securities on a pro rata basis.

     Seciion 5.    CONVERSION. The record Holders of Series C Preferred shall
have conversion rights as follows (the "Conversion Rights"):

     (a)  RIGHT TO CONVERT.

          (i)     Each record Holder of Series C Preferred shall be entitled
to convert shares of Series C Preferred at any time into that number of
fully-paid and non-assessable shares of Common of the Company calculated in
accordance with the following formula (the "Conversion Rate"):

      Number of shares issued upon conversion of one (1) share of Series C
                                   Preferred =

                             Liquidation Preference
                          ----------------------------
                                Conversion Price

where "Conversion Price" means $8.00, as adjusted herein.

     (b)  ADJUSTMENTS TO CONVERSION PRICE. The Conversion Price shall be subject
to adjustment from time to time upon the occurrence of certain events described
in this SECTION 5(b).

          (i)     SUBDIVISION OR COMBINATION OF COMMON AND COMMON DIVIDEND. In
case the Company shall at any time subdivide its outstanding Common into a
greater number of shares or declare a dividend upon the Common payable solely in
shares of Common, the Conversion Price in effect immediately prior to such
subdivision or declaration shall be proportionately reduced. Conversely, in case
the outstanding Common shall be combined into a smaller number of shares of
Common, the Conversion Price in effect immediately prior to such combination
shall be proportionately increased.

                                        2
<Page>

          (ii)    ADJUSTMENT DUE TO MERGER, CONSOLIDATION, ETC. If, prior to the
conversion of all Series C Preferred, there shall be any merger, consolidation,
exchange of shares, recapitalization, reorganization, or other similar event,
and as a result of which shares of Common of the Company shall be changed into
the same or a different number of shares of the same or another class or classes
of stock or securities of the Company or another entity, or other property, the
Holders shall be given at least 30 days advance written notice of such
transaction. The Holders shall then have the right to purchase and receive upon
conversion of Series C Preferred, upon the basis and subject to the terms and
conditions specified herein and in lieu of the shares of Common immediately
theretofore issuable upon conversion, such shares of stock and/or securities or
other property as may be issued or payable with respect to or in exchange for
the number of shares of Common immediately theretofore purchasable and
receivable upon the conversion of Series C Preferred held by such Holders had
such merger, consolidation, exchange of shares, recapitalization or
reorganization not taken place. In any such case appropriate provisions shall be
made with respect to the rights and interests of the Holders to the end that the
provisions hereof (including, without limitation, provisions for adjustment of
the Conversion Rate and of the number of shares issuable upon conversion of the
Series C Preferred) shall thereafter be applicable, as nearly as may be
practicable in relation to any shares of stock or securities thereafter
deliverable upon the conversion thereof. The Company shall not effect any
transaction described in this SUBSECTION 5(b)(ii) unless (1) each Holder has
been given at least 20 days advance written notice of such transaction, and (2)
the resulting successor or acquiring entity (if not the Company) assumes by
written instrument the obligation to deliver to the Holders such shares of stock
and/or securities or other property as, in accordance with the foregoing
provisions, the Holders of may be entitled to receive upon conversion of the
Series C Preferred. Notwithstanding the foregoing, if any of the events
described herein constitutes a Change in Control Transaction, the Holders shall
have the option, exercisable by written notice to the Company, to receive the
Liquidation Preference for their shares of Series C Preferred pursuant to
SECTION 4(b) above in lieu of their rights under this SECTION 5(b)(ii).

          (iii)   DILUTIVE ISSUANCES. If the Company shall sell or issue at any
time shares of Common (other than Excluded Securities, as defined in SECTION
5(b)(viii) below) at a consideration per share less than the Conversion Price
then in effect, the Conversion Price shall be adjusted to a new Conversion Price
(calculated to the nearest cent) determined by dividing:

                  (A)  an amount equal to (i) the total number of "Shares
Outstanding" (as defined below) immediately prior to such issuance, multiplied
by the Conversion Price in effect immediately prior to such issuance plus (ii)
the aggregate of the amount of all consideration, if any, received by the
Company upon such issuance; by

                  (B)  the total number of Shares Outstanding immediately after
such issuance or sale.

                                        3
<Page>

In no event shall any such adjustment be made pursuant to this SECTION 5(b)(iii)
if it would increase the Conversion Price in effect immediately prior to such
adjustment, except as provided in SECTIONS 5(b)(vi) AND 5(b)(vii).

          (iv)    DEFINITIONS. For purposes of this SECTION 5(b), the following
definitions shall apply:

                  (A)  "CONVERTIBLE SECURITIES" means any indebtedness or
securities convertible into or exchangeable for Common.

                  (B)  "OPTIONS" means any rights, warrants or options to

following provisions shall also be applicable:

                  (A)  CASH CONSIDERATION. In case of the issuance or sale of
additional shares of Common for cash, the consideration received by the Company
therefor shall be deemed to be the amount of cash received by the Company from
the recipients or purchasers of the additional shares of Common for such shares
of Common.

                  (B)  NON-CASH CONSIDERATION. In case of the issuance
(otherwise than upon conversion or exchange of Convertible Securities) or sale
of additional shares of Common, Options or Convertible Securities for a
consideration other than cash or a consideration a part of which shall be other
than cash, the fair value of such consideration as determined by the Board of
Directors of the Company in the good faith exercise of its business judgment,
irrespective of the accounting treatment thereof, shall be deemed to be the
value of the consideration other than cash received by the Company for such
securities.

                  (C)  OPTIONS AND CONVERTIBLE SECURITIES. In case the Company
shall in any manner issue or grant any Options or any Convertible Securities,
the total maximum number of shares of Common issuable upon the exercise of such
Options or upon conversion or exchange of the total maximum amount of such
Convertible Securities (in each case, without giving effect to any future
operation of any anti-dilution clauses in any such Option or Convertible
Securities at the time of such issuance or grant) at the time such Convertible
Securities first become convertible or exchangeable shall (as of the date of
issue or grant of such Options or, in the case of the issue or sale of
Convertible Securities other than where the same are issuable upon the exercise
of Options, as of the date of such issue or sale) be deemed to be issued and to
be outstanding for the purpose of this SECTION 5(b) and to have been issued for
the sum of the amount (if any) paid for such Options or Convertible Securities
and the amount (if any) payable upon the exercise of such Options or upon

                                        4
<Page>

conversion or exchange of such Convertible Securities at the time such
Convertible Securities first become convertible or exchangeable; PROVIDED that,
subject to the provisions of SECTION 5(b)(vi), no further adjustment of the
Conversion Price shall be made upon the actual issuance of any such shares of
Common or Convertible Securities or upon the conversion or exchange of any such
Convertible Securities.

          (vi)    CHANGE IN OPTION PRICE OR CONVERSION RATE. If the purchase
price provided for in any Option referred to in SUBSECTION 5(b)(v)(C), or the
rate at which any Convertible Securities referred to in SUBSECTION 5(b)(v)(C)
are convertible into or exchangeable for shares of Common shall change at any
time (other than under or by reason of provisions designed to protect against
dilution), then, for purposes of any adjustment required by SECTION 5(b), the
Conversion Price in effect at the time of such event shall forthwith be
readjusted to the Conversion Price that would have been in effect at such time
had such Options or Convertible Securities still outstanding provided for such
changed purchase price, additional consideration or conversion rate, as the case
may be, at the time initially granted, issued or sold, provided that if such
readjustment is an increase in the Conversion Price, such readjustment shall not
exceed the amount (as adjusted by SECTIONS 5(b)(i) and 5(b)(v)) by which the
Conversion Price was decreased pursuant to SECTION 5(b)(ii) upon the issuance of
the Option or Convertible Security. If the purchase price provided for in any
such Option referred to in SUBSECTION 5(b)(v)(C), or the additional
consideration (if any) payable upon the conversion or exchange of any
Convertible Securities referred to in SUBSECTION 5(b)(v)(C), or the rate at
which any Convertible Securities referred to in SUBSECTION 5(b)(v)(C) are
convertible into or exchangeable for shares of Common, shall be reduced at any
time under or by reason of provisions with respect thereto designed to protect
against dilution, then in case of the delivery of shares of Common upon the
exercise of any such Option or upon conversion or exchange of any such
Convertible Security; the Conversion Price then in effect hereunder shall, upon
issuance of such shares of Common be adjusted to such amount as would have
obtained had such Option or Convertible Security never been issued and had
adjustments been made only upon the issuance of the shares of Common delivered
as aforesaid and for the consideration actually received for such Option or
Convertible Security and the shares of Common, provided that if such
readjustment is an increase in the Conversion Price, such readjustment shall not
exceed the amount (as adjusted by SECTIONS 5(b)(i) AND 5(b)(iii) by which the
Conversion Price was decreased pursuant to SECTION 5(b)(iii) upon the issuance
of the Option or Convertible Security.

          (vii)   TERMINATION OF OPTION OR CONVERSION RIGHTS. In the event of
the termination or expiration of any right to purchase shares of Common under
any Option granted after the date hereof or of any right to convert or exchange
Convertible Securities issued after the date hereof, the Conversion Price shall,
upon such termination, be readjusted to the Conversion Price that would have
been in effect at the time of such expiration or termination had such Option or
Convertible Security, to the extent outstanding immediately prior to such
expiration or termination, never been issued, and the shares of Common issuable
thereunder shall no longer be deemed to be Shares Outstanding, provided that if
such readjustment is an increase in the Conversion Price, such readjustment
shall not exceed the amount (as adjusted by SECTIONS 5(b)(i) AND 5(b)(iii)) by
which the Conversion Price was decreased pursuant to SECTION 5(b)(iii) upon the
issuance of the Option or Convertible

                                        5
<Page>

Security, The termination or expiration of any right to purchase shares of
Common under any Option granted prior to the date hereof or of any right to
convert or exchange Convertible Securities issued prior to the date hereof shall
not trigger any adjustment to the Conversion Price, but the shares of Common
issuable under such Options or Convertible Securities shall no longer be counted
in determining the number of Shares Outstanding on the date hereof for purposes
of subsequent calculations under this SECTION 5(b).

          (viii)  EXCLUDED SECURITIES. Notwithstanding anything herein to the
contrary, the Conversion Price shall not be adjusted pursuant to this SECTION
5(b) by virtue of the issuance and/or sale of "Excluded Securities", which means
the following: (a) up to 682,185 shares of Common, Options or Convertible
Securities to be issued and/or sold to employees, advisors (including, without
limitation, financial, technical and legal advisers), directors or officers of,
or consultants to, the Company or any of its subsidiaries pursuant to a stock
grant, stock option plan, stock purchase plan, pension or profit sharing plan or
other stock agreement or arrangement existing as of the date hereof and which
has been approved by the stockholders of the Company; (b) the reissuance of any
expired and unexercised, cancelled or forfeited Options under any plan referred
to in SUBSECTION (a) above; (c) the issuance of shares of Common, Options and/or
Convertible Securities pursuant to Options and Convertible Securities
outstanding as of the date hereof; (d) the issuance of shares of Common, Options
or Convertible Securities as a stock dividend or upon any subdivision or
combination of shares of Common or Convertible Securities; (e) the issuance of
shares of Common pursuant to the exercise of certain warrants to be issued in
connection with the issuance of the shares of Series C Preferred; or (f) shares
of Common or Convertible Securities issued and sold by and for the account of
the Company pursuant to an effective registration statement filed by the Company
pursuant to the Securities and Exchange Act of 1934, as amended. For all
purposes of this SECTION 5(b), all shares of Common which are Excluded
Securities shall be deemed to have been issued for an amount of consideration
per share equal to the Conversion Price in effect at the time of issuance.

          (ix)    All calculations under this SECTION 5(b) shall be made to the
nearest one half of one cent ($.005) or to the nearest one-tenth of a share, as
the case may be.

          (x)     NOTICE OF ADJUSTMENT. Promptly after adjustment of the
Conversion Price, the Company shall give written notice thereof, by first class
mail, postage prepaid, addressed to the registered Holders at the address of
such Holders as shown on the books of the Company. The notice shall be signed by
an officer of the Company and shall state the effective date of the adjustment
and the Conversion Price resulting from such adjustment, setting forth in
reasonable detail the method of calculation and the facts upon which such
calculation is based.

     (c)  MECHANICS OF CONVERSION. Conversion of the Series C Preferred to
Common may be exercised in whole or in part by a Holder telecopying an executed
and completed notice of conversion ("Notice of Conversion") to the transfer
agent of the Company (the "Transfer Agent"), with a copy to the Company, and
delivering the original Notice of Conversion and the certificate representing
the shares of Series C Preferred to the Transfer Agent by hand or by express
courier within three (3) business days of exercise. Each date on which a Notice

                                        6
<Page>

of Conversion is telecopied to the Transfer Agent in accordance with the
provisions hereof shall be deemed a "Conversion Date." The Transfer Agent will
transmit the certificates representing the Common issuable upon conversion of
all or any part of the shares of Series C Preferred (together with any
certificates for replacement shares of Series C Preferred not previously
converted but included in the original certificate presented for conversion) to
the Holder via express courier within three (3) business days after the Transfer
Agent has received the original Notice of Conversion and certificate for the
shares of Series C Preferred being so converted. The Notice of Conversion and
certificate representing the portion of the shares of Series C Preferred
converted shall be delivered as follows:

                  To the Transfer Agent:

                  American Stock Transfer & Co.
                  40 Wall Street
                  New York, NY 10005
                  Attn.: Mr. Isaac Kagan
                  (Tel)(718) 921-8293
                  (Fax)(718) 921-8334

                  To the Company:

                  KTI, Inc.
                  7000 Boulevard East
                  Guttenberg, NJ 07093
                  Attn.: President
                  (Tel)  201-854-7777
                  (Fax)  201-854-1771

or to such other person at such other place as the Company shall designate to
the Holder in writing. The Company shall immediately notify each Holder of any
change of Transfer Agent for the Company or termination of the existing Transfer
Agent. If there is no Transfer Agent at any time, all references in this SECTION
5(c) to "Transfer Agent" shall be deemed to refer to the Company.

          (i)     NO FRACTIONAL SHARES. No fractional shares shall be issued
upon the conversion of the Series C Preferred. The Company shall pay to any
Holder who has converted all or any portion of the shares of Series C Preferred
cash in an amount equal to any fractional shares, such amount of cash to be
determined by multiplying the closing trading price on the last trading day
prior to the date of the conversion by the amount of the fractional share.

     (d)  LOST OR STOLEN CERTIFICATES. Upon receipt by the Company of evidence
of the loss, theft, destruction or mutilation of any certificates representing
shares of Series C Preferred, and (in the case of loss, theft or destruction) of
indemnity or security reasonably satisfactory to the Company, and upon surrender
and cancellation of the certificate(s), if mutilated, the Company shall execute
and deliver new certificate(s) of like tenor and date.

                                        7
<Page>

However, Company shall not be obligated to re-issue such lost or stolen
certificates if Holder contemporaneously requests Company to convert such Series
C Preferred into Common.

     (e)  MANDATORY CONVERSION. The Series C Preferred is subject to mandatory
conversion, at which time all shares of Series C Preferred will automatically be
converted at the Conversion Price, (i) upon the completion of a firm
underwritten public offering of Common by the Company (a "Public Offering") in
which (a) gross proceeds to the Company, before expenses and underwriters'
discounts and commissions, of at least $20,000,000 are received, (b) the Common
so offered is sold at an offering price per share to the public of at least 200%
of the Conversion Price then in effect, and (c) the Holders receive, as a
consequence of participation in such Public Offering, net proceeds equal to or
greater than $3,900,000 (a Public Offering which meets the conditions set forth
in (a), (b) and (c) above being referred to as a "Qualified Public Offering"),
or (ii) immediately following the completion of a Public Offering that is not a
Qualified Public Offering, but, (a) in which the Company receives gross
proceeds, before expenses and underwriters' discounts and commissions, of at
least $20,000,000, and (b) upon the "Market Price" (as defined below) for each
share of Common exceeding 200% of the Conversion Price then in effect for twenty
(20) consecutive trading days, and the average daily trading volume of the
Common for such twenty (20) consecutive day period exceeding 10,000 shares.
"Market Price" shall mean the closing bid price for the Common, as reported by
the Nasdaq National Market System ("Nasdaq"), or if the Common is not traded on
Nasdaq, the closing price or, if not available, the low price of the Common in
the over-the-counter market or the principal national securities exchange on
which the Common is traded.

     (f)  RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The Company shall at
all times reserve and keep available out of its authorized but unissued shares
of Common such number of its shares of Common as shall from time to time be
sufficient to effect the conversion of all then outstanding shares of Series C
Preferred. The Company covenants and agrees that if at any time it would be
unable to fully convert all shares of Series C Preferred then outstanding, it
will promptly use its best efforts to obtain stockholder approval, within 135
days thereafter, to amend its Certificate of Incorporation to increase the
number of authorized shares of Common by an amount sufficient to permit the
conversion of all shares of Series C Preferred then outstanding.

     (g)  REDEMPTION BY COMPANY.

          (i)     REDEMPTION DATE. The Company shall redeem all outstanding
shares of the Series C Preferred on the fifth anniversary of the date of the
original issuance of the shares of Series A Preferred (the "Redemption Date").

          (ii)    REDEMPTION PRICE. The redemption price per share of Series C
Preferred shall equal $12.00 per share of Series C Preferred (to be adjusted
proportionately if the shares of Series C Preferred to which such amount is
applicable are subdivided into a greater number or combined into a lesser
number).

                                        8
<Page>

          (iii)   MECHANICS OF REDEMPTION. The Company shall effect each such
redemption by giving notice thereof ("Redemption Notice"), by facsimile, by
5 P.M. New York City time no later than the tenth (10th) business day prior to
the Redemption Date and shall provide a copy of such redemption notice by
overnight or 2-day courier, to each Holder and the Company's transfer agent for
the Series C Preferred ("Series C Transfer Agent"). Such redemption notice shall
indicate the applicable redemption price and whether the Company has elected, at
its option, to redeem the shares of Series C Preferred for cash (a "Cash
Redemption") or for Common (a "Redemption for Stock"). In the event of a
Redemption for Stock, the Company shall also specify in the Redemption Notice
the number of shares of Common to be issued to the Holder, which shall be based
on the following formula:

      Number of shares issued upon redemption of one (1) share of Series C
                                   Preferred =

                                Redemption Price
                          -----------------------------
                            Adjusted Conversion Price

where, the "Adjusted Conversion Price" shall equal ninety five percent (95%) of
the average closing sale price of the Common as reported by Nasdaq for the
previous twenty (20) trading days ending on the day before the Redemption Date.

          (iv)    HOLDER'S CONVERSION RIGHTS. Notwithstanding the foregoing.
Holder shall have five business days following receipt of the Redemption Notice
from the Company to elect, in its sole discretion, to convert all or part of the
Series C Preferred otherwise being redeemed. Such conversion shall be effected
in accordance with the provisions of SECTION 5 hereof, and if an appropriate
Notice of Conversion is delivered to the Company in a timely manner, such shares
of Series C Preferred shall be deemed to be converted and not redeemed.

          (v)     OPTIONAL REDEMPTION. Upon a "Change of Control Transaction"
(as defined herein), the Company shall redeem, at the option of the Holder, upon
receipt of a written redemption request from such Holder, the Series C Preferred
either through Cash Redemption or a Redemption for Stock, at the option of the
Company. In the event of a Cash Redemption, the Company shall issue cash for the
accreted value of the shares of Series C Preferred, which shall be the initial
purchase price of $8 per share plus interest of 8.19 percent per annum
calculated based on the number of actual days elapsed in a 365 day year or 366
day year, as appropriate, from June 4, 1997 plus any dividends which have been
declared and which the Holders are entitled to receive with respect to each
share of Series C Preferred (the "Accreted Value"). In the event of a Redemption
for Stock, the number of shares of Common to be issued to the Holder shall be
based on the following formula:

      Number of shares issued upon redemption of one (1) share of Series C
                                   Preferred =

                                 Accreted Value
                         -------------------------------
                            Adjusted Conversion Price

                                        9
<Page>

where, the "Adjusted Conversion Price" shall equal ninety five percent (95%) of
the average closing bid price of the Common as reported by Nasdaq for the
previous ten (10) business days ending on the day before the Redemption Date.

A "Change of Control Transaction," is defined as any merger, consolidation or
reorganization of the Company pursuant to which shares of capital stock of the
Company are converted into cash, securities or other property in which the
holders of a majority of the voting capital stock of the Company (on an
as-converted and exercised basis) immediately prior thereto beneficially own,
directly or indirectly, less than 50% Of the combined voting power of the
capital stock of the company surviving or resulting from such merger,
consolidation or reorganization.

          (vi)    PAYMENT OF REDEMPTION PRICE OR ISSUANCE OF SHARE CERTIFICATES.
Upon receipt of a Redemption Notice, Holder shall send its shares of Series C
Preferred being redeemed to the Company or its Series C Transfer Agent, and the
Company shall pay the applicable redemption price within three (3) business days
of receipt of the shares of Series C Preferred, if a Cash Redemption, or issue
certificates representing shares of Common, if a Redemption for Stock. The
Company shall not be obligated to deliver the redemption price or shares of
Common, as the case may be, unless the shares of Series C Preferred so redeemed
are delivered to the Company or its Series C Transfer Agent, or, in the event
one or more certificates have been lost, stolen, mutilated or destroyed, Holder
delivers to the Company a lost certificate affidavit and indemnification
agreement reasonably satisfactory to the Company and the Series C Transfer
Agent. Any redemption payment owed to any Holder under this SECTION 5(g) which
is not paid when due shall bear interest at a rate of 4% in excess of the prime
rate of interest in effect as announced by KeyBank of New York.

     Section 6.   VOTING RIGHTS. The Holder of each outstanding share of
Series C Preferred shall have the right to one vote for each share of Common
into which each such share of Series C Preferred could then be converted
(assuming, for this purpose only, that shares of Series C Preferred are
convertible into fractional shares) at the record date for the determination of
stockholders entitled to vote on such matters or, if no such record date is
established, at the date of such vote is taken or any written consent of
stockholders is solicited. With respect to such vote, such Holder shall have
full voting rights and powers equal to the voting rights and powers of the
holders of shares of Common, shall be entitled to notice of any stockholders'
meeting in accordance with the By-Laws of the Company, and shall be entitled to
vote, together with holders of shares of Common, with respect to any question
upon which stockholders of the Company have the right to vote. With respect to
all matters upon which stockholders of the Company are entitled to vote, the
holders of outstanding shares of Common and the Holders of all outstanding
shares of Series C Preferred shall vote together without regard to class, except
as expressly required herein, by the Certificate of Incorporation and the
By-Laws of the Company or the Business Corporation Law of the State of New
Jersey.

     Section 7.   STATUS OF CONVERTED STOCK. If any shares of Series C Preferred
shall be converted pursuant to SECTION 5 above, the shares so converted shall be
canceled, shall return

                                       10
<Page>

to the status of authorized but unissued Preferred Stock of no designated
series, and shall not be issuable by the Company as Series C Preferred.

     Section 8.   PROTECTIVE PROVISION. So long as shares of Series C Preferred
are outstanding, the Company shall not without first obtaining the approval (by
vote or written consent, as provided by the applicable laws of the State of New
Jersey) of the Holders of at least a majority of the then outstanding shares of
Series C Preferred;

     (a)  alter or change the rights, preferences or privileges of the Series C
Preferred so as to affect adversely the Series C Preferred;

     (b)  increase the size of the authorized number of Series C Preferred; or

     (c)  do any act or thing not authorized or contemplated by this Certificate
of Designation which would result in taxation of the Holders of shares of the
Series C Preferred under Section 305 of the Internal Revenue Code of 1986, as
amended (or any comparable provision of the Internal Revenue Code as hereafter
from time to time amended).

     If Holders of at least a majority of the then outstanding shares of Series
C Preferred agree to allow the Company to alter or change the rights,
preferences or privileges of the shares of Series C Preferred, pursuant to
SUBSECTION 8(a) above, so as to affect the Series C Preferred, then the Company
will promptly deliver notice of such approved change to the Holders that did not
agree to such alteration or change."

     3.   Such resolution was duly adopted by the Board of Directors of the
Corporation on May 28, 1997.

     4.   The Restated Certificate of Incorporation, as amended, is amended so
that the designation and number of shares of each class and series acted upon in
the resolution, and the relative rights, preferences and limitations of each
such class and series, are as stated in the resolution.

                                       11

     IN WITNESS WHEREOF, the Corporation has caused this Certificate of
Amendment to be executed on its behalf this 28th day of October, 1997.

2. The inaccuracies in the Certificate are (indicate inaccuracies or defects):

          (a)  The word "fractional" on the thirteenth line on page 6 of the
          Certificate was incorrectly spelled "factional".

          (b)  The last line of Section 6(b)(i) on page 14 of the Certificate
          refers to the redemption price, as opposed to the Redemption Date.

          (c)  Section 8(a)(i) on page 20 of the Certificate failed to state the
          rate at which the Corporation may convert the Series B Convertible
          Exchangeable Preferred Stock into the Corporation's 8 3/4% Convertible
          Subordinated Notes due 2004.

          (d)  Section 9(a) on page 23 of the Certificate failed to specify that
          a Change of Control Payment may be made at the Option of the
          Corporation either in cash or, in certain circumstances, shares of
          common stock of the Corporation.

3. The Certificate of Correction hereby reads as follows:

          (a)  The word "factional" on the thirteenth line on page 6 of the

          (b)  The last line of Section 6(b)(i) on page 14 of the Certificate is
          hereby amended by deleting "redemption price" and replacing it with

                    Notes for each share of Series B Preferred and
                    which Exchange Notes will be convertible into
                    Common Stock of the Corporation at the Conversion
                    Price which would have been applicable to the
                    Series B Preferred if the Series B Preferred had
