Item 5.  Other Information

(a)  In July 1993, the Company executed comprehensive amendments to its bank
credit facility (the "Credit Facility") and note purchase agreements (the
"Senior Notes").  On November 18, 1994, the Company reached an agreement in
principle regarding additional amendments, and on November 23, 1994 executed
such amendments (the "Amendments") to its Credit Facility and Senior Note
agreements, which include waivers (with respect to noncompliance of
consolidated working capital, consolidated tangible net worth and financial
statement delivery covenants) and revisions to the terms and conditions of the
Credit Facility and Senior Note agreements, principally with respect to payment
terms and compliance covenants.

The Amendments provide that 90% of the $74,421,000 scheduled payments
previously due on July 1, 1995 will be deferred until July 1, 1996, with
further deferral to December 31, 1996, at the Company's option, of up to 75% of
the $95,512,000 scheduled payments previously due on October 31, 1995 and
December 30, 1995 and all of the $95,512,000 aggregate scheduled payments due
on October 31, 1996 and December 30, 1996.  Certain of such scheduled payments
due in 1995 and 1996 will be reduced by pro rata payments made prior to the
scheduled payment dates.  The non- deferred portion of these scheduled payments
will be applied to reduce Senior Note obligations, industrial revenue bond
obligations and letters of credit issued under the Credit Facility.  The
Amendments also provide that the remaining originally scheduled principal
payments on the Senior Notes due after 1996 become due on December 31, 1996.

The Amendments require, however, that the Company reduce Senior Note and Credit
Facility obligations by a total of $60,000,000, primarily through the payment
of the non-deferred portions of the scheduled payments discussed above and
other scheduled payments, between August 31, 1994 and December 31, 1995, of
which $20,000,000 must occur buy January 31, 1995.  Of this amount, $13,189,000
has been paid to date.  Portions of the remaining required payments are
expected to be satisfied by currently available funds and operating cash flow,
and in the absence of a refinancing of the Senior Note and Credit Facility
obligations during 1995, the Company will need to complete additional
divestitures to satisfy any remaining payments.  Under the Amendments, the
Company is also required to pay to the holders of the Senior Notes and the
Credit Facility banks, the amount by which its daily average unrestricted cash
balance exceeds $40,000,000 for any calendar month, and a minimum of 50% of the
net proceeds from specified divestitures as permitted by the Amendments, which
proceeds will be applied to the $60,000,000 discussed above.

The Company  is endeavoring to complete a refinancing of the Senior Note and
Credit Facility obligations by April 30, 1995.  At the time of refinancing, the
Company may be required to pay an early redemption premium to the Senior Note
holders (the "Premium") based on the difference between the interest rates on
the Senior Notes and an adjusted rate for U.S. Treasury securities having
a similar maturity.  Based on current interest rates on U.S. Treasury 
securities, on April 30, 1995 the Premium would be approximately $5,691,000.





                                     - 2 -
<PAGE>   3


The Amendments also require payment of escalating extension fees by the Company
to the Senior Note holders and Credit Facility banks, based upon the principal
amounts outstanding as of the beginning of each calendar quarter, until such
time as the existing debt under these agreements has been retired.  Such
extension fees are expected to aggregate approximately $652,000 through April
30, 1995.  The total of the extension fees and the Premium is an estimate and
the actual amount will depend on the actual time of the refinancing and the
average principal amounts outstanding under the Senior Notes through that
period.  The extension fees and the Premium will be charged to expense during
the period ending with the refinancing.  A fee of approximately $673,000 was
paid upon final execution of the Amendments.

The Amendments also provide, under certain conditions, for the issuance to the
Senior Note holders and Credit Facility banks, at nominal consideration, shares
of the Company's Class A Common Stock.  In the event that the Company has not
refinanced the Senior Note and Credit Facility obligations prior to October 1,
1995, shares of Class A Common Stock equivalent to 4% of the Company's then
issued and outstanding Common Stock and Class A Common Stock become issuable.
An additional 4% becomes issuable if the Company has not refinanced prior to
April 1, 1996.

The Amendments contain financial covenants which require the Company to
maintain minimum levels of tangible net worth, working capital and quarterly
cash flows from operations.  The Amendments also prohibit the incurrence of
additional indebtedness and the payment of cash dividends, and limit annual
cash capital expenditures.

The Company believes that a refinancing cannot be obtained without the final
settlement of certain shareholder litigation.  Further, the payments required
under the settlement of the shareholder litigation would require the
refinancing of the Senior Notes and Credit Facility obligations.  In the event
that a refinancing is not achieved, the liquidity and operations of the Company
would be materially and adversely affected.

(b)  On November 28, 1994, the Company entered into an agreement and plan of
merger with USA Waste Services, Inc. ("USA Waste") and a wholly-owned
subsidiary of USA Waste (the "Merger Agreement"), pursuant to which the
subsidiary would merge with and into the Company, and USA Waste would issue
0.41667 shares of its common stock, subject to certain adjustments, for each
share of the Company's Class A Common Stock and Common Stock outstanding.  As a
result of the merger, the Company would become a wholly-owned subsidiary of USA
Waste.  USA Waste, which has 22,575,263 shares of common stock outstanding,
would issue an aggregate of approximately 27.8 million shares of its common
stock in connection with the merger, assuming no adjustment to the exchange
ratio.  The merger is subject, among other things, to the receipt by each party
of an opinion from its investment banking firm relating to the financial
fairness of the merger to its respective shareholders, the approval of the
shareholders of both USA Waste and the Company, appropriate assurances as to
the treatment of the merger as a tax-free reorganization accounted for as a
pooling of interests, expiration of the waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, final
settlement of the shareholder litigation involving the Company, and certain
other conditions.  It is anticipated that completion of the merger will require
approximately six months.


In connection with the Merger Agreement, USA Waste received proxies from
certain of the Company's shareholders authorizing USA Waste to vote such shares
in favor of the merger, subject to certain conditions and for a limited term.
The shares covered by these proxies have voting rights representing a majority
of the voting rights of all outstanding shares of the Company entitled to vote
on the merger.  The Company has also received proxies from certain of USA
Waste's shareholders similarly authorizing the Company to vote such shares in
favor of the merger.

             WHEREAS, Parent, Subsidiary and the Company are entering into this
Agreement in order to effectuate the merger of Subsidiary with and into the
Company (the "Merger"), as a result of which the Company will become a
wholly-owned subsidiary of Parent;

             WHEREAS, concurrently with the execution hereof, and in order to
facilitate the consummation of the Merger, certain stockholders of Parent and
certain stockholders of the Company are executing and delivering certain other

             WHEREAS, Parent, Subsidiary and the Company intend the Merger to
qualify as a tax-free reorganization under the provisions of Section 368 of the

thereunder.

             NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements contained herein, the

or as soon as practicable after the closing of the transactions contemplated by
this Agreement in accordance with Section 3.5. The parties acknowledge that it
is their mutual desire and intent to consummate the Merger as soon as

reasonable efforts to consummate, as soon as practicable, the transactions
contemplated by this Agreement in accordance with Section 3.5.


                                   ARTICLE II

                     THE SURVIVING AND PARENT CORPORATIONS

             SECTION 2.1.     CERTIFICATE OF INCORPORATION.  The Certificate of
Incorporation of Subsidiary as in effect immediately prior to the Effective

after the Effective Time, and thereafter may be amended in accordance with its
terms and as provided in the DGCL.

             SECTION 2.2.     BY-LAWS.  The By-laws of Subsidiary as in effect
immediately prior to the Effective Time shall be the By-laws of the Surviving

accordance with their terms and as provided by the Certificate of Incorporation
of the Surviving Corporation and the DGCL.

             SECTION 2.3.     DIRECTORS.  (a) The Board of Directors of Parent
shall take such corporate action as may be necessary to cause Parent's Board of
Directors immediately following the Effective Time to be composed of five
members designated by the Board of Directors of Parent and four members
designated by the Board of Directors of the Company.

             (b)     The Board of Directors of Parent shall take such corporate
action immediately prior to the Effective Time as may be necessary to appoint
an Executive Committee of Parent's Board of Directors immediately following the

of Directors of Parent and two members selected by the Board of Directors of
the Company.

             SECTION 2.4.     OFFICERS.  Except as otherwise agreed to by

with the By-laws of the Surviving Corporation until their respective successors
are duly elected or appointed and qualified.


                                  ARTICLE III

                              CONVERSION OF SHARES

             SECTION 3.1.     CONVERSION OF COMPANY SHARES IN THE MERGER.  At
the Effective Time, by virtue of the Merger and without any action on the part
of any holder of any capital stock of the Company:

             (a)     each share of the Company's Common Stock, par value $.50
    per share (the "Regular Common Stock"), and each share of the Company's
    Class A Common Stock, par value $.50 per share (the "Class A Common Stock"
    and, together with the Regular Common Stock, the "Company Common Stock"),
    shall, subject to Sections 3.3 and 3.4, be converted into the right to
    receive, without interest, .41667 (the "Exchange Ratio") of a share of the
    common stock, par value $.01 per share, of Parent ("Parent Common Stock");
    provided, however, that (i) in the event that the Average Market Price is
    greater than $18.00, the "Exchange Ratio" shall be determined by dividing
    $7.50 by the lesser of $19.20 or the Average Market Price, and (ii) in the
    event that the Average Market Price is less than $10.80, the "Exchange
    Ratio" shall be determined by dividing $4.50 by the Average Market Price.
    As used herein, "Average Market Price" means the average of the closing
    prices of Parent Common Stock (rounded to the nearest one thousandth) on
    the ten (10) days immediately prior to the fifth day prior to the Closing
    Date that Parent Common Stock is traded on the New York Stock Exchange and
    for which closing prices are reported in The Wall Street Journal (or such
    other publication mutually agreed to by the Parent and the Company);

             (b)     each share of capital stock of the Company, if any, owned
    by Parent or any subsidiary of Parent or held in treasury by the Company or
    any subsidiary of the Company immediately prior to the Effective Time shall
    be cancelled and shall cease to exist from and after the Effective Time;
    and

             (c)     subject to and as more fully provided in Section 7.9, each
    unexpired option to purchase Company Common Stock that is outstanding at
    the Effective Time, whether or not exercisable, shall automatically and
    without any action on the part of the holder thereof be converted into an
    option to purchase a number of shares of Parent Common Stock equal to the
    number of shares of Company Common Stock that could be purchased under such
    option multiplied





                                      -3-
<PAGE>   5
    by the Exchange Ratio, at a price per share of Parent Common Stock equal 
    to the per share exercise price of such option divided by the 
    Exchange Ratio.

             SECTION 3.2.     CONVERSION OF SUBSIDIARY SHARES.  At the
Effective Time, by virtue of the Merger and without any action on the part of
Parent as the sole stockholder of Subsidiary, each issued and outstanding share
of common stock, par value $.001 per share, of Subsidiary ("Subsidiary Common
Stock") shall be converted into one share of common stock, par value $.50 per
share, of the Surviving Corporation.

             SECTION 3.3.     EXCHANGE OF CERTIFICATES.  (a) From and after the
Effective Time, each holder of an outstanding certificate which immediately
prior to the Effective Time represented shares of Company Common Stock shall be
entitled to receive in exchange therefor, upon surrender thereof to an exchange
agent reasonably satisfactory to Parent and the Company (the "Exchange Agent"),
a certificate or certificates representing the number of whole shares of Parent
Common Stock to which such holder is entitled pursuant to Section 3.1(a).
Notwithstanding any other provision of this Agreement, (i) until holders or
transferees of certificates theretofore representing shares of Company Common
Stock have surrendered them for exchange as provided herein, no dividends shall
be paid with respect to any shares represented by such certificates and no
payment for fractional shares shall be made and (ii) without regard to when
such certificates representing shares of Company Common Stock are surrendered
for exchange as provided herein, no interest shall be paid on any dividends or
any payment for fractional shares.  Upon surrender of a certificate which
immediately prior to the Effective Time represented shares of Company Common
Stock, there shall be paid to the holder of such certificate the amount of any
dividends which theretofore became payable, but which were not paid by reason
of the foregoing, with respect to the number of whole shares of Parent Common
Stock represented by the certificate or certificates issued upon such
surrender.

             (b)     If any certificate for shares of Parent Common Stock is to
be issued in a name other than that in which the certificate for shares of
Company Common Stock surrendered in exchange therefor is registered, it shall
be a condition of such exchange that the person requesting such exchange shall
pay any transfer or other taxes required by reason of the issuance of
certificates for such shares of Parent Common Stock in a name other than that
of the registered holder of the certificate surrendered, or shall establish to
the satisfaction of Parent that such tax has been paid or is not applicable.

             (c)     Promptly after the Effective Time, Parent shall make
available to the Exchange Agent the certificates representing shares of Parent
Common Stock required to effect the exchanges referred to in paragraph (a)
above and cash for payment of any fractional shares referred to in Section 3.4.

             (d)     Promptly after the Effective Time, the Exchange Agent
shall mail to each holder of record of a certificate or certificates that
immediately prior to the Effective Time represented outstanding shares of
Company Common Stock (the "Company Certificates") (i) a form letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Company Certificates shall pass, only upon actual
delivery of the Company Certificates to the Exchange Agent) and (ii)
instructions for use in effecting the surrender of the Company Certificates in
exchange for certificates representing shares of Parent Common Stock.  Upon
surrender of Company Certificates for cancellation to the Exchange Agent,
together with a duly executed letter of transmittal and such other documents as
the Exchange Agent shall reasonably require, the holder of such Company
Certificates shall be entitled to receive in exchange therefor a certificate
representing that number of whole shares of Parent Common Stock into which the
shares of Company Common Stock theretofore represented by the Company
Certificates so surrendered shall have been converted pursuant to the
provisions of Section 3.1(a), and the Company Certificates so surrendered shall
forthwith be cancelled.  Notwithstanding the foregoing, neither the Exchange
Agent nor any party hereto shall be liable to a holder of shares of Company
Common Stock for any shares of Parent Common Stock or dividends or
distributions thereon delivered to a public official pursuant to applicable
abandoned property, escheat or similar laws.

             (e)     Promptly following the date which is nine months after the
Effective Date, the Exchange Agent shall deliver to Parent all cash,
certificates (including any Parent Common Stock) and other documents in its
possession relating to the transactions described in this Agreement, and the
Exchange Agent's duties shall terminate.  Thereafter, each holder of a Company
Certificate may surrender such Company Certificate to the Surviving Corporation
and (subject to applicable abandoned property, escheat and similar laws)
receive in exchange therefor the Parent Common Stock, without any interest
thereon.  Notwithstanding the foregoing, none of the Exchange Agent, Parent,
Subsidiary, the Company or the Surviving Corporation shall be liable to a
holder of Company Common Stock for any Parent Common Stock delivered to a
public official pursuant to applicable abandoned property, escheat and similar
laws.

             (f)     In the event any Company Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Company Certificate to be lost, stolen or destroyed, the
Surviving Corporation shall issue in exchange for such lost, stolen or
destroyed Company Certificate the Parent Common Stock deliverable in respect
thereof determined in accordance with this Article III.  When authorizing such
payment in exchange therefor, the Board of Directors of the Surviving
Corporation may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed Company
Certificate to give the 




                                      -5-
<PAGE>   7

Surviving Corporation such indemnity as it may reasonably direct as protection
against any claim that may be made against the Surviving Corporation with 
respect to the Company Certificate alleged to have been lost, stolen or 
destroyed.

             SECTION 3.4.     NO FRACTIONAL SECURITIES.  Notwithstanding any
other provision of this Agreement, no certificates or scrip for fractional
shares of Parent Common Stock shall be issued in the Merger and no Parent
Common Stock dividend, stock split or interest shall relate to any fractional
security, and such fractional interests shall not entitle the owner thereof to
vote or to any other rights of a security holder.  In lieu of any such
fractional shares, each holder of Company Common Stock who would otherwise have
been entitled to receive a fraction of a share of Parent Common Stock upon
surrender of Company Certificates for exchange pursuant to this Article III
shall be entitled to receive from the Exchange Agent a cash payment equal to
such fraction multiplied by the closing price per share of Parent Common Stock
on the New York Stock Exchange, as reported by the Wall Street Journal, on the
last trading day preceding the Effective Time.

             SECTION 3.5.     CLOSING.  The closing (the "Closing") of the
transactions contemplated by this Agreement shall take place at a location
mutually agreeable to Parent and the Company on the fifth business day
immediately following the date on which the last of the conditions set forth in
Article VIII is fulfilled or waived, or at such other time and place as Parent
and the Company shall agree (the date on which the Closing occurs is referred
to in this Agreement as the "Closing Date").

             SECTION 3.6.     CLOSING OF THE COMPANY'S TRANSFER BOOKS.  At and
after the Effective Time, holders of Company Certificates shall cease to have
any rights as stockholders of the Company, except for the right to receive
shares of Parent Common Stock pursuant to Section 3.3 and the right to receive
cash for payment of fractional shares pursuant to Section 3.4.  At the
Effective Time, the stock transfer books of the Company shall be closed and no
transfer of shares of Company Common Stock which were outstanding immediately
prior to the Effective Time shall thereafter be made.  If, after the Effective
Time, subject to the terms and conditions of this Agreement, Company
Certificates formerly representing Company Common Stock are presented to the
Surviving Corporation, they shall be cancelled and exchanged for Parent Common
Stock in accordance with this Article III.

Subsidiary is qualified to do business and is in good standing in each
jurisdiction in which the properties owned, leased or operated by it or the
nature of the business conducted by it makes such qualification necessary,
except where the failure to be so qualified and in good standing will not, when
taken together with all other such failures, have a material adverse effect on
the business, operations, properties, assets, condition (financial or other),
results of operations or prospects of Parent and its subsidiaries, taken as a
whole. True, accurate and complete copies of each of Parent's and Subsidiary's
Certificates of Incorporation and By-laws, in each case as in effect on the
date hereof, including all amendments thereto, have heretofore been (or, in the
case of Subsidiary, will promptly be) delivered to the Company.

    SECTION 4.2.     CAPITALIZATION.  (a) The authorized capital stock of
Parent consists of (i) 50,000,000 shares of Parent Common Stock, of which
22,575,263 shares were outstanding as of November 10, 1994, and (ii) 10,000,000
shares of preferred stock, par value $.01 per share, none of which was issued

hereof, there are no outstanding subscriptions, options, calls, contracts,
commitments, understandings, restrictions, arrangements, rights or warrants,

additional shares of the capital stock of Parent or obligating Parent or any
subsidiary of Parent to grant, extend or enter into any such agreement or

and authority to own, lease and operate its assets and properties and to carry
on its business as it is now being conducted. Each subsidiary of Parent is
qualified to do business, and is in good standing, in each jurisdiction in
which the properties owned, leased or operated by it or the nature of the
business conducted by it makes such qualification necessary, except where the
failure to be so qualified and in good standing would not, when taken together
with all such other failures, have a material adverse effect on the business,
operations, properties, assets, condition (financial or other), results of
operations or prospects of Parent and its subsidiaries, taken as a whole.  All
of the outstanding shares of capital stock of each corporate subsidiary of
Parent are validly issued, fully paid, nonassessable and free of preemptive
rights, and are owned directly or indirectly by Parent, free and clear of any
liens, claims or encumbrances except that such shares are pledged to secure
Parent's credit facilities.  There are no subscriptions, options, warrants,
rights, calls, contracts, voting trusts, proxies or other commitments,
understandings, restrictions or arrangements relating to the issuance, sale,
voting, transfer, ownership or other rights with respect to any shares of
capital stock of any corporate subsidiary of Parent, including any right of
conversion or exchange under any outstanding security, instrument or agreement.

or of which such person or entity (either acting alone or together with its
other subsidiaries) owns, directly or indirectly, 50% or more of the stock or
other voting interests, the holders of which are entitled to vote for the
election of a majority of the board of directors or any similar governing body
of such corporation, partnership, joint venture or other entity.  Parent does

with its terms, except that such enforcement may be subject to (i) bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting or
relating to enforcement of creditors' rights generally and (ii) general
equitable principles.  Without limitation of the foregoing, each of the
covenants and obligations of Parent set forth in Sections 6.2, 6.5, 7.3, 7.6,
7.7, 7.8 and 7.11 is valid, legally binding and enforceable notwithstanding the
absence of the Parent Stockholders' Approval.

    (b)      The execution and delivery of this Agreement by each of Parent and
Subsidiary do not violate, conflict with or result in a breach of any provision
of, or constitute a default (or an event which, with notice or lapse of time or
both, would constitute a default) under, or result in the termination of, or

franchise, permit, concession, contract, lease or other instrument, obligation
or agreement of any kind to which Parent or any of its subsidiaries is now a
party or by which Parent or any of its subsidiaries or any of their respective
properties or assets may be bound or affected.  The consummation by Parent and
Subsidiary of the transactions contemplated hereby will not result in any
violation, conflict, breach, termination, acceleration or creation of liens
under any of the terms, conditions or provisions described in clauses (i)
through (iii) of the preceding sentence, subject (x) in the case of the terms,
conditions or provisions described in clause (ii) above, to obtaining (prior to

provisions described in clause (iii) above, to obtaining (prior to the
Effective Time) consents required from commercial lenders, lessors or other

the execution and delivery of this Agreement by Parent or Subsidiary or the
consummation by Parent or Subsidiary of the transactions contemplated hereby,
other than such declarations, filings, registrations, notices, authorizations,
consents or approvals which, if not made or obtained, as the case may be, would
not, in the aggregate, have a material adverse effect on the business,
operations, properties, assets, condition (financial or other), results of
operations or prospects of Parent and its subsidiaries, taken as a whole.

subsidiaries, taken as a whole.

    SECTION 4.8.     LITIGATION.  Except as disclosed in the Parent SEC Reports

commission, agency, instrumentality or authority, or any arbitrator that seek
to restrain or enjoin the consummation of the Merger or which could reasonably
be expected, either alone or in the aggregate with all such claims, actions or
proceedings, to materially and adversely affect the business, operations,
properties, assets, condition (financial or other), results of operations or
prospects of Parent and its subsidiaries, taken as a whole.  Except as set

material respects with all applicable laws, including the provisions of the
Securities Act and the Exchange Act and the rules and regulations promulgated
thereunder, except that no representation is made by Parent or Subsidiary with
respect to information supplied by the Company or the Majority Stockholders for

<PAGE>   14
regulation, ordinance, or judgment (including, without limitation, any
applicable environmental law, ordinance or regulation) of any governmental or
regulatory body or authority, except for violations which, in the aggregate,
could not reasonably be expected to have a material adverse effect on the
business, operations, properties, assets, condition (financial or other),
results of operations or prospects of Parent and its subsidiaries, taken as a
whole.  Except as disclosed in the Parent SEC Reports, as of the date of this
Agreement, to the knowledge of Parent, no investigation or review by any
governmental or regulatory body or authority is pending or threatened, nor has
any governmental or regulatory body or authority indicated an intention to
conduct the same, other than, in each case, those the outcome of which, as far
as reasonably can be foreseen, will not have a material adverse effect on the
business, operations, properties, assets, condition (financial or other),
results of operations or prospects of the Parent and its subsidiaries, taken as
a whole.  Parent and its subsidiaries have all permits, licenses, franchises,
variances, exemptions, orders and other governmental authorizations, consents
and approvals necessary to conduct their businesses as presently conducted
(collectively, the "Parent Permits"), except for permits, licenses, franchises,
variances, exemptions, orders, authorizations, consents and approvals the
absence of which, alone or in the aggregate, would not have a material adverse
effect on the business, operations, properties, assets, condition (financial or
other), results of operations or prospects of the Parent and its subsidiaries,
taken as a whole.  Parent and its subsidiaries are not in violation of the
terms of any Parent Permit, except for delays in filing reports or violations
which, alone or in the aggregate, would not have a material adverse effect on
the business, operations, properties, assets, condition (financial or other),
results of operations or prospects of the Parent and its subsidiaries, taken as
a whole.

    SECTION 4.11.    COMPLIANCE WITH AGREEMENTS.  Except as disclosed in the
Parent SEC Reports, Parent and each of its subsidiaries are not in breach or
violation of or in default in the performance or observance of any term or
provision of, and no event has occurred which, with lapse of time or action by
a third party, could result in a default under (a) the respective charters,
by-laws or other similar organizational instruments of Parent or any of its
subsidiaries or (b) any contract, commitment, agreement, indenture, mortgage,
loan agreement, note, lease, bond, license, approval or other instrument to
which Parent or any of its subsidiaries is a party or by which any of them is
bound or to which any of their property is subject, which breaches, violations
and defaults, in the case of clause (b) of this Section 4.11, would have, in
the aggregate, a material adverse effect on the business, operations,
properties, assets, condition (financial or other), results of operations or
prospects of Parent and its subsidiaries, taken as a whole.

    SECTION 4.12.    TAXES.  (a)  Parent and its subsidiaries have (i) duly
filed with the appropriate governmental authorities all Tax Returns (as defined
in Section 





                                      -13-
<PAGE>   15

4.12(c)) required to be filed by them for all periods ending on or
prior to the Effective Time, other than those Tax Returns the failure of which
to file would not have a material adverse effect on the business, operations,
properties, assets, condition (financial or other), results of operations or
prospects of Parent and its subsidiaries, taken as a whole, and such Tax
Returns are true, correct and complete in all material respects and (ii) duly
paid in full or made adequate provision for the payment of all Taxes (as
defined in Section 4.12(b)) for all periods ending at or prior to the Effective

for all periods ending at or prior to the Effective Time and there are no
material liens for Taxes upon any property or assets of Parent or any
subsidiary thereof, except for liens for Taxes not yet due.  There are no
unresolved issues of law or fact arising out of a notice of deficiency,
proposed deficiency or assessment from the Internal Revenue Service (the "IRS")
or any other governmental taxing authority with respect to Taxes of the Parent
or any of its subsidiaries which, if decided adversely, singly or in the
aggregate, would have a material adverse effect on the business, operations,
properties, assets, condition (financial or other), results of operations or
prospects of Parent and its subsidiaries, taken as a whole.  Neither Parent nor
any of its subsidiaries is a party to any agreement providing for the
allocation or sharing of Taxes with any entity that is not, directly or
indirectly, a wholly-owned corporate subsidiary of Parent other than agreements
the consequences of which are fully and adequately reserved for in the Parent
Financial Statements.  Neither Parent nor any of its corporate subsidiaries
has, with regard to any assets or property held, acquired or to be acquired by
any of them, filed a consent to the application of Section 341(f) of the Code.

sales, withholding, social security, occupation, use, service, service use,
license, payroll, franchise, transfer and recording taxes, fees and charges,
windfall profits, severance, customs, import, export, employment or similar
taxes, charges, fees, levies or other assessments imposed by the United States,
or any state, local or foreign government or subdivision or agency thereof,
whether computed on a separate, consolidated, unitary, combined or any other
basis, and such term shall include any interest, fines, penalties or additional
amounts and any interest in respect of any additions, fines or penalties

"accumulated funding deficiency" (as defined in Section 302 of ERISA and

recent fiscal year of each of the Parent Plans ended prior to the date of this
Agreement, (v) the current present value of all projected benefit obligations
under each of the Parent Plans which is subject to Title IV of ERISA did not,
as of its latest valuation date, exceed the then current value of the assets of

any, disclosed in the Parent SEC Reports as of September 30, 1994, based upon
reasonable actuarial assumptions currently utilized for such Parent Plan, (vi)
each of the Parent Plans has been operated and administered in all material
respects in accordance with applicable laws during the period of time covered

may be necessary to make additional amendments retroactively to maintain the
"qualified" status of such Parent Plans, and the period for making any such
necessary retroactive amendments has not expired, (viii) with respect to
Multi-employer Plans, neither Parent nor any of its subsidiaries has made or
suffered a "complete withdrawal" or a "partial withdrawal," as such terms are
respectively defined in Sections 4203, 4204 and 4205 of ERISA and, to the best
knowledge of Parent and its subsidiaries, no event has occurred or is expected
to occur which presents a material risk of a complete or partial withdrawal
under said Sections 4203, 4204 and 4205, (ix) to the best knowledge of Parent
and its subsidiaries, there are no material pending, threatened or anticipated
claims involving any of the Parent Plans other than claims for benefits in the
ordinary course, and (x) Parent and its subsidiaries have no current material
liability for plan termination or withdrawal (complete or partial) under Title
IV of ERISA based on any plan to which any entity that would be deemed one
employer with Parent and its subsidiaries under Section 4001 of ERISA or
Section 414 of the Code contributed during the period of time covered by the
applicable statute of limitations (a "Parent Controlled Group Plan"), and
Parent and its subsidiaries do not reasonably anticipate that any such
liability will be asserted against Parent or any of its subsidiaries.  None of

its business as it is now being conducted.  The Company is qualified to do
business and is in good standing in each jurisdiction in which the properties
owned, leased or operated by it or the nature of the business conducted by it
makes such qualification necessary, except where the failure to be so qualified

failures, have a material adverse effect on the business, operations,
properties, assets, condition (financial or other), results of operations or
prospects of the Company and its subsidiaries, taken as a whole. True, accurate
and complete copies of the Company's Certificate of Incorporation and By-laws,
in each case as in effect on the date hereof, including all amendments thereto,

business, and is in good standing, in each jurisdiction in which the properties
owned, leased or operated by it or the nature of the business conducted by it

properties, assets, condition (financial or other), results of operations or
prospects of the Company and its subsidiaries, taken as a whole.  All of the
outstanding shares of capital stock of each corporate subsidiary of the Company
are validly issued, fully paid, nonassessable and free of preemptive rights and

trusts, proxies or other commitments, understandings, restrictions or
arrangements relating to the issuance, sale, voting, transfer, ownership or
other rights with respect to any shares of capital stock of any corporate
subsidiary of the Company, including any right of conversion or exchange under
any outstanding security, instrument or agreement.

its subsidiaries is in violation of or has been given notice or been charged
with any violation of, any law, statute, order, rule, regulation, ordinance or
judgment (including, without limitation, any applicable environmental law,
ordinance or regulation) of any governmental or regulatory body or authority,
except for violations which, in the aggregate, could not reasonably be expected
to have a material adverse effect on the business, operations, properties,
assets, condition (financial or other), results of operations or prospects of
the Company and its subsidiaries, taken as a whole.  Except as disclosed in the
Company SEC Reports, as of the date of this Agreement, to the knowledge of the
Company, no investigation or review by any governmental or regulatory body or
authority is pending or threatened, nor has any governmental or regulatory body
or authority indicated an intention to conduct the same, other than, in each
case, those the outcome of which, as far as reasonably can be foreseen, will
not have a material adverse effect on the business, operations, properties,
assets, condition (financial or other), results of operations or prospects of
the Company and its subsidiaries taken as a whole.  The Company and its
subsidiaries have all permits, licenses, franchises, variances, exemptions,
orders and other governmental authorizations, consents and approvals necessary
to conduct their businesses as presently conducted (collectively, the "Company
Permits"), except for permits, licenses, franchises, variances, exemptions,
orders, authorizations, consents and approvals the absence of which, alone or
in the aggregate, would not have a material adverse effect on the business,
operations, properties, assets, condition (financial or other), results of
operations or prospects of the Company and its subsidiaries, taken as a whole.
The Company and its subsidiaries are not in violation of the terms of any
Company Permit, except for delays in filing reports or violations which, alone
or in the aggregate, would not have a material adverse effect on the business,
operations, properties, assets, condition (financial or other), results of
operations or prospects of the Company and its subsidiaries, taken as a whole.

    SECTION 5.11.    COMPLIANCE WITH AGREEMENTS.  Except as disclosed in the
Company SEC Reports, the Company and each of its subsidiaries are not in breach
or violation of or in default in the performance or observance of any term or
provision of, and no event has occurred which, with lapse of time or action by
a third party, could result in a default under, (a) the respective charters,
by-laws or similar organizational instruments of the Company or any of its
subsidiaries or (b) any contract, commitment, agreement, indenture, mortgage,
loan agreement, note, lease, bond, license, approval or other instrument to
which the Company or any of its subsidiaries is a party or by which any of them
is bound or to which any of their property is subject, which breaches,
violations and defaults, in the case of clause (b) of this Section 5.11, would

properties, assets, condition (financial or other), results of operations or 
prospects of the Company and its subsidiaries, taken as a whole.

    SECTION 5.12.    TAXES.  The Company and its subsidiaries have (i) duly
filed with the appropriate governmental authorities all Tax Returns required to
be filed by them for all periods ending on or prior to the Effective Time,
other than those Tax Returns the failure of which to file would not have a
material adverse effect on the business, operations, properties, assets,
condition (financial or other), results of operations or prospects of the
Company and its subsidiaries, taken as a whole, and such Tax Returns are true,
correct and complete in all material respects, and (ii) duly paid in full or
made adequate provision for the payment of all Taxes for all periods ending at
or prior to the Effective Time.  The liabilities and reserves for Taxes
reflected in the Company balance sheet included in the latest Company SEC
Report are adequate to cover all Taxes for all periods ending at or prior to
the Effective Time and there are no material liens for Taxes upon any property
or asset of the Company or any subsidiary thereof, except for liens for Taxes
not yet due.  There are no unresolved issues of law or fact arising out of a
notice of deficiency, proposed deficiency or assessment from the IRS or any
other governmental taxing authority with respect to Taxes of the Company or any
of its subsidiaries which, if decided adversely, singly or in the aggregate,
would have a material adverse effect on the business, operations, properties,
assets, condition (financial or other), results of operations or prospects of
the Company and its subsidiaries, taken as a whole.  Neither the Company nor
any of its subsidiaries is a party to any agreement providing for the
allocation or sharing of Taxes with any entity that is not, directly or
indirectly, a wholly-owned corporate subsidiary of Company.  Neither the
Company nor any of its corporate subsidiaries has, with regard to any assets or
property held, acquired or to be acquired by any of them, filed a consent to
the application of Section 341(f) of the Code.

arrangements and practices (such plans, programs, arrangements and practices of
the Company and its subsidiaries being referred to as the "Company Plans"),
including employee benefit plans within the meaning set forth in Section 3(3)
of ERISA, or other similar material arrangements for the provision of benefits
(excluding any "Multi-employer Plan" within the meaning of Section 3(37) of
ERISA or a "Multiple Employer Plan" within the meaning of Section 413(c) of the
Code).  Schedule 5.13(a) attached hereto lists all Multi-employer Plans and
Multiple Employer Plans which any of the Company or its subsidiaries maintains
or to which any of them makes contributions.  Neither the Company nor its
subsidiaries has any obligation to create any additional such plan or to amend

the terms of the Company Plans, under existing collective bargaining 
agreements or to comply with applicable law.

aggregate, could have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) results of operations or
prospects of the Company and its subsidiaries, taken as a whole, (ii) except
for premiums due, there is no outstanding material liability, whether measured
alone or in the aggregate, under Title IV of ERISA with respect to any of the

described in Section 4041(b) of ERISA, (iv) none of the Company Plans has
incurred any "accumulated funding deficiency" (as defined in Section 302 of
ERISA and Section 412 of the Code), whether or not waived, as of the last day
of the most recent fiscal year of each of the Company Plans ended prior to the
date of this Agreement, (v) the current present value of all projected benefit
obligations under each of the Company Plans which is subject to Title IV of
ERISA did not, as of its latest valuation date, exceed the then current value
of the assets of such plan allocable to such benefit liabilities by more than
the amount, if any, disclosed in the Company SEC Reports as of September 30,
1994, based upon reasonable actuarial assumptions currently utilized for such
Company Plan, (vi) each of the Company Plans has been operated and administered
in all material respects in accordance with applicable laws during the period
of time covered by the applicable statute of limitations, (vii) each of the
Company Plans which is intended to be "qualified" within the meaning of Section
401(a) of the Code has been determined by the Internal Revenue Service to be so
qualified and such determination has not been modified, revoked or limited by
failure to satisfy any condition thereof or by a subsequent amendment thereto
or a failure to amend, except that it may be necessary to make additional
amendments retroactively to 



                                      -27-

maintain the "qualified" status of such Company Plans, and the period
for making any such necessary retroactive amendments has not expired, (viii)
with respect to Multi-employer Plans, neither the Company nor any of its
subsidiaries has, made or suffered a "complete withdrawal" or a "partial
withdrawal," as such terms are respectively defined in Sections 4203, 4204 and
4205 of ERISA and, to the best knowledge of the Company and its subsidiaries,
no event has occurred or is expected to occur which presents a material risk of
a complete or partial withdrawal under said Sections 4203, 4204 and 4205, (ix)
to the best knowledge of the Company and its subsidiaries, there are no
material pending, threatened or anticipated claims involving any of the Company
Plans other than claims for benefits in the ordinary course, and (x) the
Company and its subsidiaries have no current material liability, whether
measured alone or in the aggregate, for plan termination or withdrawal
(complete or partial) under Title IV of ERISA based on any plan to which any
entity that would be deemed one employer with the Company and its subsidiaries
under Section 4001 of ERISA or Section 414 of the Code contributed during the
period of time covered by the applicable statute of limitations (the "Company
Controlled Group Plans"), and the Company and its subsidiaries do not
reasonably anticipate that any such liability will be asserted against the
Company or any of its subsidiaries.  None of the Company Controlled Group Plans
has an "accumulated funding deficiency" (as defined in Section 302 of ERISA and
412 of the Code).

    (c)      The Company SEC Reports contain a true and complete summary or
list of or otherwise describe all material employment contracts and other
employee benefit arrangements with "change of control" or similar provisions
and all severance agreements with executive officers.

Company, asserted that the Company or any of its subsidiaries is liable in any
material amount for any arrears of wages or any taxes or penalties for failure
to comply with any of the foregoing, except for such controversies,
organizational efforts, non-compliance and liabilities which, singly or in the
aggregate, could not reasonably be expected to materially and adversely 





                                      -28-
<PAGE>   30


affect the business, operations, properties, assets, condition

been no environmental investigations, studies, audits, tests, reviews or other

Environmental Law conducted by or which are in the possession of the Company or
its subsidiaries relating to the activities of the Company or its subsidiaries
which have not been delivered to Parent prior to the date hereof, (viii) there

wastes, chemical or hazardous wastes, liquid and other waste collection,
interim storage, transfer, recovery, processing, recycling, marketing or
disposal or any other material business currently engaged in by the Parent or
the Company, or any corporations affiliated with either of them.  None of the
Company's officers, directors or key employees is a party to any agreement

any material respect the Company or any subsidiary of the Company from, 
directly or indirectly, engaging in any of the businesses described above.

the lien of current taxes, payments of which are not yet delinquent, (ii) such
imperfections in title and easements and encumbrances, if any, as are not

Merger, such vote would constitute the requisite approval of the Company's

board of directors of the Company or the Parent, as the case may be, is advised
by one or more of its independent financial advisors that providing
confidential or non-public information to the Potential Acquirer is likely to
lead to an Acquisition Transaction on terms that would yield a materially
higher value to the Company's or the Parent's stockholders, as the case may be,
than the Merger and (iii) based upon advice of its independent legal counsel,
its board of directors determines in good faith that there is a significant
risk that the failure to provide such confidential or non-public information to
such Potential Acquirer would constitute a breach of its fiduciary duty to its
stockholders.

    (c)      In the event either party hereto shall determine to provide any
information or negotiate as described in paragraph (b) above, or shall receive
any offer of the type referred to in paragraph (b) above, it shall promptly
inform the other party hereto that information is to be provided, that
negotiations are to take place or that an offer has been 


                                      -35-
<PAGE>   37

received and shall furnish to the other party hereto the identity of
the person receiving such information or the proponent of such offer, if
applicable, and, if an offer has been received, a description of the material
terms thereof.

    (d)      A party hereto may enter into a definitive agreement for an
Acquisition Transaction which meets the requirements set forth above with a
Potential Acquirer with which it is permitted to negotiate pursuant to
paragraph (b) above, but only if (i) the board of directors of such party shall
have duly determined that such Acquisition Transaction would yield a materially
higher value to such party's stockholders than the Merger and that the
execution of such definitive agreement is in the best interests of such party's
stockholders, (ii) at least ten business days prior to the execution of such
definitive agreement, such party shall have furnished the other party hereto
with a copy of such definitive agreement and (iii) such other party shall have
failed within such ten-day period to offer to amend the terms of this Agreement
in order that the Merger would yield a value to such party's stockholders at
least equal to the Acquisition Transaction.  In making the determination
required by clause (i) above, the board of directors referred to therein shall
consider all relevant considerations and factors, including, without
limitation, the form and value of the consideration, the extent to which the
economic benefits of the Acquisition Transaction differ from the economic
benefits contemplated by this Agreement, the likelihood that the Potential
Acquirer will be able to obtain financing to consummate the Acquisition
Transaction, the proposed closing date, the certainty of consummation,
antitrust issues and closing conditions.

    (e)      Each party (i) acknowledges that a breach of any of its covenants
contained in this Section 6.5 will result in irreparable harm to the other
party which will not be compensable in money damages and (ii) agrees that such
covenant shall be specifically enforceable and that specific performance and
injunctive relief shall be a remedy properly available to the other party for a
breach of such covenant.

similarly destroy their documents, memoranda and notes), and such destruction
(and reasonable best efforts) shall be certified in writing by an authorized
officer supervising such destruction.

    (c)      The Company shall promptly advise Parent and Parent shall promptly
advise the Company in writing of any change or the occurrence of any event

Parent's shares of Subsidiary Common Stock for adoption and approval of this
Agreement and the transactions contemplated hereby and shall take all
additional actions as the sole stockholder of Subsidiary necessary to adopt and
approve this Agreement and the transactions contemplated hereby. Parent (i)
acknowledges that a breach of its covenant contained in this Section 7.3(b) to
convene a meeting of its stockholders and call for a vote thereat with respect
to the approval of this Agreement and the Merger will result in irreparable
harm to the Company which will not be compensable in money damages and (ii)

performance and injunctive relief shall be a remedy properly available to the
Company for a breach of such covenant.

    SECTION 7.4.   COMPLIANCE WITH THE SECURITIES ACT.  Parent and the
Company shall each use its reasonable best efforts to cause each principal
executive officer, each director and each other person who is an "affiliate,"
as that term is used in paragraphs (c) and (d) of Rule 145 under the Securities
Act, of Parent or the Company, as the case may be, to deliver to Parent and the
Company on or prior to the Effective Time a written agreement (an "Affiliate
Agreement") to the effect that such person will not offer to sell, sell or
otherwise dispose of any shares of Parent Common Stock issued in the Merger,
except, in each case, pursuant to an effective registration statement or in
compliance with Rule 145, as amended from time to time, or in a transaction
which, in the opinion of legal counsel satisfactory to Parent, is exempt from
the registration requirements of the Securities Act and, in any case, until
after the results covering 30 days of post-Merger combined operations of Parent
and the Company have been filed with the SEC, sent to stockholders of Parent or
otherwise publicly issued.

    SECTION 7.5.   EXCHANGE LISTING.  Parent shall use its reasonable best
efforts to effect, at or before the Effective Time, authorization for listing
on the New York Stock Exchange Inc. (the "NYSE"), upon official notice of
issuance, of the shares of Parent Common Stock to be issued pursuant to the
Merger.

    SECTION 7.6.   EXPENSES AND FEES.  (a) Except as provided in Section 7.6(b)
or Section 7.6(c), all costs and expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be paid by the party
incurring such expenses, except that those expenses incurred in connection with
printing the Joint Proxy Statement/Prospectus shall be shared equally by Parent
and the Company.

    (b)      The Company agrees to pay to Parent a fee equal to $28,000,000

                     merger or other acquisition transaction equal to or

                     its stockholders to receive consideration having a fair 
                     value on the date of the first public announcement of

             (4)     another person acquires all or any substantial portion of
                     the Company's assets under terms which provide for the
                     Company and/or its stockholders to receive consideration
                     having a fair value on the date of the first public
                     announcement of such acquisition transaction equal to or

    SECTION 7.7.   AGREEMENT TO COOPERATE.  (a) Subject to the terms and
conditions herein provided, each of the parties hereto shall use all reasonable
efforts to take, or cause to be taken, all action and to do, or cause to be
done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated by
this Agreement, including using its reasonable efforts to obtain all necessary
or appropriate waivers, consents and approvals and SEC "no-action" letters to
effect all necessary registrations, filings and submissions and to lift any
injunction or other legal bar to the Merger (and, in such case, to proceed with
the Merger as expeditiously as possible), subject, however, to the requisite
votes of the stockholders and boards of directors of the Company and Parent.

    (b)      Without limitation of the foregoing, each of Parent and the
Company undertakes and agrees to file as soon as practicable after the date
hereof a Notification and Report Form under the HSR Act with the Federal Trade
Commission (the "FTC") and the Antitrust Division of the Department of Justice
(the "Antitrust Division").  Each of Parent and the Company shall (i) use its
reasonable efforts to comply as expeditiously as possible with all lawful
requests of the FTC or the Antitrust Division for additional information and
documents and (ii) not extend any waiting period under the HSR Act or enter
into any agreement with the FTC or the Antitrust Division not to consummate the
transactions contemplated by this Agreement, except with the prior consent of
the other parties hereto.

    (c)      In the event any litigation is commenced by any person or entity
relating to the transactions contemplated by this Agreement, including any

Agreement, a mutually acceptable plan which includes the following:  (i) the

(iii) the financing of a $45 million settlement payment payable by the 
Company in or about March 1996.

    SECTION 7.8.   PUBLIC STATEMENTS.  The parties shall consult with each
other prior to issuing any press release or any written public statement with
respect to this Agreement or the transactions contemplated hereby and shall not
issue any such press release or written public statement prior to such
consultation.

    SECTION 7.9.   OPTION PLANS.   Prior to the Effective Time, the Company
and Parent shall take such action as may be necessary to cause each unexpired
and unexercised option (each a "Company Option") to be automatically converted
at the Effective Time into an option (each a "Parent Option") to purchase a
number of shares of Parent Common Stock equal to the number of shares of
Company Common Stock that could have been purchased under the Company Option
multiplied by the Exchange Ratio, at a price per share of Parent Common Stock
equal to the option exercise price determined pursuant to the Company Option
divided by the Exchange Ratio and subject to the same terms and conditions as
the Company Option.  The date of grant of the substituted Parent Option shall
be the date on which the corresponding Company Option was granted.  At the
Effective Time, all references in the stock option agreements to the Company
shall be deemed to refer to Parent. Parent shall assume all of the Company's
obligations with respect to Company Options as so amended and shall, from and
after the Effective Time, make available for issuance upon exercise of the
Parent Options all shares of Parent Common Stock covered thereby and amend its
Registration Statement on Form S-8 to cover the additional shares of Parent
Common Stock subject to Parent Options granted in replacement of Company
Options.

    SECTION 7.10.   EMPLOYEE BENEFITS AND LOANS.  Parent acknowledges its
intention, after the Effective Time, that employees of the Company who continue
after the Merger shall be provided with benefits which are no less favorable
than those provided by Parent to its own employees.  Loans heretofore made by
the Company to directors, officers and employees for the purpose of purchasing
Company Common Stock will be forgiven to the extent written down prior to the
date of this Agreement, as reflected in the Company SEC Reports (but excluding
loans to any former officers, directors or employees of the Company who have
asserted claims against the Company that remain pending).

    SECTION 7.11.   NOTIFICATION OF CERTAIN MATTERS.  Each of the Company,
Parent and Subsidiary agrees to give prompt notice to each other of, and to use
their respective reasonable best efforts to prevent or promptly remedy, (i) the
occurrence or failure to occur or the impending or threatened occurrence or
failure to occur, of any event which occurrence or failure to occur would be
likely to cause any of its representa-





                                      -42-
<PAGE>   44

tions or warranties in this Agreement to be untrue or inaccurate in any
material respect at any time from the date hereof to the Effective Time and
(ii) any material failure on its part to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it hereunder;
provided, however, that the delivery of any notice pursuant to this Section
7.11 shall not limit or otherwise affect the remedies available hereunder to
the party receiving such notice.

    SECTION 7.12.   DIRECTORS' AND OFFICERS' INDEMNIFICATION.  (a) After
the Effective Time, the Surviving Corporation shall, to the fullest extent
permitted under applicable law, indemnify and hold harmless, each present and
former director, officer, employee and agent of the Company or any of its
subsidiaries (each, together with such person's heirs, executors or
administrators, an "indemnified Party" and collectively, the "indemnified
Parties") against any costs or expenses (including attorneys fees), judgments,
fines, losses, claims, damages, liabilities and amounts paid in settlement in
connection with any claim, action, suit, proceeding or investigation, whether
civil, criminal, administrative or investigative, arising out of, relating to
or in connection with any action or omission occurring prior to the Effective
Time (including, without limitation, acts or omissions in connection with such
persons serving as an officer, director or other fiduciary in any entity if
such service was at the request or for the benefit of the Company) or arising
out of or pertaining to the transactions contemplated by this Agreement. In the
event of any such claim, action, suit, proceeding or investigation (whether
arising before or after the Effective Time), (i) the Company or Parent and the
Surviving Corporation, as the case may be, shall pay the reasonable fees and
expenses of counsel selected by the indemnified Parties, which counsel shall be
reasonably satisfactory to the Parent and the Surviving Corporation, promptly
after statements therefor are received, (ii) the Parent and the Surviving
Corporation will cooperate in the defense of any such matter, and (iii) any
determination required to be made with respect to whether an indemnified
Party's conduct complies with the standards set forth under the DGCL and the
Parent's or the Surviving Corporation's respective Certificates of
Incorporation or By-Laws shall be made by independent legal counsel acceptable
to the Parent or the Surviving Corporation, as the case may be, and the
indemnified Party; provided, however, that neither Parent nor the Surviving
Corporation shall be liable for any settlement effected without its written
consent (which consent shall not be unreasonably withheld).

    (b)      In the event the Surviving Corporation or Parent or any of their
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person, then and in each such case, proper
provisions shall be made so that the successors and assigns of the 



                                      -43-
<PAGE>   45

Surviving Corporation or Parent shall assume the obligations set forth in 
this Section 7.12.

    SECTION 7.13.   CORRECTIONS TO THE JOINT PROXY STATEMENT/PROSPECTUS AND
REGISTRATION STATEMENT.  Prior to the date of approval of the Merger by their
respective stockholders, each of the Company, Parent and Subsidiary shall
correct promptly any information provided by it to be used specifically in the
Joint Proxy Statement/Prospectus and Registration Statement that shall have
become false or misleading in any material respect and shall take all steps
necessary to file with the SEC and have declared effective or cleared by the
SEC any amendment or supplement to the Joint Proxy Statement/Prospectus or the
Registration Statement so as to correct the same and to cause the Joint Proxy
Statement/Prospectus as so corrected to be disseminated to the stockholders of
the Company and Parent, in each case to the extent required by applicable law.

   amounts required to be paid under this subsection (iii).  Payments made under
   this subsection (iii) during the period from August 31, 1994 through January
   31, 1995 in excess of $20,000,000 shall be credited against (and serve to
   reduce) amounts required to be paid for the period from February 1, 1995

   subsection (iii).

     (iv)   Other.  The Borrower shall promptly make any and all other payments
   required under the Intercreditor Agreement.

   (b)  Cash Collateral Account.  There has been established under the
  Intercreditor Agreement a Cash Collateral Account for the primary benefit of
  the Banks in respect of outstanding Letters of Credit, and as secondary
  benefit to the Lenders generally under the Intercreditor Agreement.  Inasmuch
  as it is expected that most, if not all, of the credit exposure of the Banks
  will consist, at any time, of undrawn Letters of Credit, the Banks' pro rata
  share of prepayments hereunder and under the Intercreditor Agreement will be
  paid into the Cash Collateral Account for application as provided therein.

   (c)  Application of Prepayments.  The share of prepayments and other amounts
  paid to the Collateral Agent in respect of and for application to the Letter
  of Credit Obligations shall be promptly applied from the Cash Collateral
  Account established and maintained under the Intercreditor Agreement

   year of such payment, whether as scheduled payments, sinking fund
   redemptions, mandatory prepayment or redemption or otherwise, by purchase of
   such VRDN Obligations for surrender and delivery to the Trustee in respect
   of such payments,

     (ii) second, to the extent possible and reasonably practicable, to the
   replacement or permanent reduction of Landfill Closure and Performance
   Letters of Credit, and

     (iii) third, to optional redemption of VRDN Obligations agreed to by the
   Majority Banks in inverse order of principal installment maturities, whether
   as scheduled payments, sinking fund redemptions, mandatory prepayment or
   redemption or otherwise, by purchase of such VRDN Obligations for surrender
   and delivery to the Trustee in respect of such payments.

   (d)  Lien Releases.  The Collateral Agent will, in accordance with the terms
  of the Intercreditor Agreement, release liens in connection with asset sales
  and dispositions upon receipt of, among other things, 50% of the Net Proceeds
  from the sale or disposition of any assets and businesses described in
  Exhibit J attached, and 100% of the Net Proceeds from the sale or disposition
  of the Harrison landfill or the Atlanta landfill and/or collections
  operations.  As used herein, "Net Proceeds" means the gross proceeds from an
  asset sale or disposition minus reasonable and necessary expenses directly
  incurred in such sale and minus any debt obligations (other than VRDN
  Obligations) incurred by the Borrower (or its Subsidiaries) in connection
  with the acquisition of the assets being sold which the Borrower (or its
  Subsidiaries) elects, or is required, to repay in connection with the sale of
  such assets and minus any amounts incurred to satisfy leases on such assets.
  Interest accrued or payable on any of the Obligations shall not be deducted
  from such gross proceeds.

purchase money financings to "July 1, 1995" is amended and deemed replaced with
"December 31, 1996".

   "Memoranda of Understanding" means that Memorandum or those Memoranda of     
  Understanding approved and executed by the Borrower as of November 18, 1994
  regarding settlement of various legal proceedings relating to the accounting
  adjustments announced March 17, 1992, copies of which have been provided to
  each of the Banks.
          
  2.  The parties hereby acknowledge and agree that from the date of this
Amendment and hereafter any reaffirmation of the representation in Section
4.01(f) regarding the absence of any material adverse change in the Borrower's
condition, financial or otherwise, shall be made exclusive of the effect of, or
payments under, the Memoranda of Understanding.
  
  3.  Subsections (o) and (p) of Section 5.01 regarding the Working Capital and
Tangible Net Worth covenants, respectively, are amended and restated to read as
follows:
  
   (o)  Working Capital.  The Borrower will not permit Consolidated Working     
  Capital to be less than $25,000,000 at any time; provided, however, that a
  reduction in Consolidated Working Capital below $25,000,000 for less than 31
  days due to a prepayment using excess Unrestricted Cash Balances pursuant to
  Section 2.02(a)(ii) shall not constitute a violation of this Section 5.01(o);
  and provided further, that notwithstanding anything contained herein to the
  contrary, for purposes hereof in determining Consolidated Current Liabilities
  there shall be excluded all charges and payments to be made under the
  Memoranda of Understanding.
   
   (q)  Tangible Net Worth.  The Borrower will not permit Consolidated Tangible 
  Net Worth at any time to be less than $100,000,000; provided, however, that

  written consent of the Majority Banks, make any payments on, under or in
  respect of the Memoranda of Understanding.

  5.  The references in subsections (i) and (ii) of Section 7.01(b) to

  6.  The Banks hereby acknowledge receipt of the Memoranda of Understanding,
and hereby waive (i) receipt of the Borrower's quarterly financial information
for the third quarter of 1994 until the date 60 days after the end of such
quarter, and (ii) any other Default or Event of Default which may exist on
account of the execution (but not of performance which shall be subject to the
terms of the Loan Agreement as amended hereby) of the Memoranda of
Understanding.
  
  B.  This Amendment shall be effective upon execution hereof by the Borrower,
the Guarantors and the Majority Banks.
  
  C.  Reference is hereby made to that amended, modified and restated guaranty
agreement (the "Chambers Guaranty") dated as of March 15, 1991 given by the
Borrower in connection with Letters of Credit issued or to be issued for the
account of a Subsidiary.  The Borrower hereby acknowledges and agrees that
references in the Chambers Guaranty to "Loan Agreement" shall be deemed to be
references to the Amended, Modified and Restated Loan Agreement dated as of
March 15, 1991 among the Borrower, the Banks and the Agent, as amended by the
First, Second, Third, Fourth, Fifth, Sixth, Seventh, Eighth and this Ninth
Amendment.
  
  The Borrower hereby restates and reaffirms that it unconditionally guarantees
to the Agent and the Banks the payment of the Indebtedness (as such term is
defined in the Chambers Guaranty) when and as the same shall become due in
accordance with the terms of the Chambers Guaranty.  Though not required by the
terms of the Chambers Guaranty, the Borrower hereby acknowledges and consents
to the changes in the Loan Agreement and the Loan Documents, as amended hereby
or in connection herewith.
  
  D.  Reference is hereby made to those Guaranty Agreements (collectively, the
"Subsidiary Guaranty") dated as of March 15, 1991 and December 23, 1992 given
by those parties shown as a Guarantor on the signature pages thereto and
hereto, each being, directly or indirectly, a wholly-owned subsidiary of the
Borrower (collectively, the "Guarantors" and individually a "Guarantor"), for
the benefit of the Borrower.  Each of the Guarantors hereby acknowledges and
agrees that references in the Subsidiary Guaranty to "Loan Agreement" shall be
deemed to be references to the Amended, Modified and Restated Loan Agreement
dated as of March 15, 1991 among the Borrower, the Banks and the Agent, as
amended by the First, Second, Third, Fourth, Fifth, Sixth, Seventh, Eighth and
this Ninth Amendment.
      
  Each of the Guarantors hereby restates and reaffirms that it unconditionally
jointly and severally guarantees to the Agent and the Banks and their
respective successors, indorsees,

transferees, and assigns, the payment, when due, by acceleration or otherwise,
of the Indebtedness (as such term is defined in the Subsidiary Guaranty) in
accordance with the terms of the Subsidiary Guaranty Agreement; provided that,
as provided therein, the liability of each Guarantor with respect to the
Indebtedness so guaranteed shall not exceed the Maximum Guaranteed Amount (as
defined and determined in the Subsidiary Guaranty).  Though not required by the
terms of the Subsidiary Guaranty, each of the Guarantors hereby acknowledges
and consents to the changes in the Loan Agreement and the Loan Documents, as
amended hereby or in connection herewith.

  E.  The Borrower and the Guarantors will execute such additional documents as
are reasonably requested by the Agent to reflect the terms and conditions of
this Ninth Amendment.
      
  F.  The Borrower hereby represents and warrants that no Default or Event of
Default exists and is continuing under the Loan Agreement as of the date of,
and after giving effect to, this Ninth Amendment (except as set forth in
Schedule A attached hereto).  It is further agreed that the Defaults and Events
of Default set out in Schedule A are waived, but only through the date hereof. 
Except as amended hereby, all of the terms and provisions of the Loan Agreement
remain in full force and effect.
      
  G.  The Borrower agrees to pay all reasonable costs and expenses (with
appropriate supporting documentation) in connection with the preparation,
execution and delivery of and compliance with this Ninth Amendment, including
without limitation the reasonable fees and expenses of Moore & Van Allen,
counsel to the Agent and the Banks.
      
  H.  This Ninth Amendment may be executed in any number of counterparts, each
of which when so executed and delivered shall be deemed an original and it
shall not be necessary in making proof of this Ninth Amendment to produce or
account for more than one such counterpart.
      
  I.  This Ninth Amendment and the Loan Agreement, as amended hereby, shall be
deemed to be contracts made under, and for all purposes shall be construed in
accordance with the laws of the State of North Carolina.

                                                         As of November 21, 1994

To the Holder Whose Name
   Appears in the Acceptance
   Form at the End Hereof

Gentlemen:

                 Reference is made to the Note Purchase Agreement dated as of
November 15, 1988 between Chambers Development Company, Inc., a Delaware
corporation (the "Company"), and each of the purchasers named therein pursuant
to which $30,000,000 aggregate principal amount of the Company's 10.95% Senior
Notes due October 31, 1998 were issued.  The Note Purchase Agreement
subsequently was amended by a Waiver and First Amendment to Note Purchase
Agreement dated December 23, 1992 (the "Waiver") and an Extension of Waiver and
Second Amendment to Note Purchase Agreement dated February 26, 1993 (the
"Extension"), and was amended and restated (the "Restatement") as of July 9,
1993.  The Note Purchase Agreement as amended by the Waiver and the Extension,
as amended and restated by the Restatement and as further amended and restated
herein is hereinafter referred to as the "Agreement."  Simultaneously with the
execution and delivery hereof, the Company is entering into agreements (the
"Other Agreements") with the other Institutional Investors named in Annex 2
(herein called the "Other Holders"), substantially identical with this
Agreement.  This Agreement and the Other Agreements are sometimes referred to
herein collectively as the "Agreements".

                 The Company and the guarantors of the payment and performance
of this Agreement and the Notes whose names appear on the signature pages
hereof (the "Guarantors"), intending to be legally bound, hereby, jointly and
severally agree with you as follows:

                 1.       Authorization of Notes and Common Stock.  The Company
has authorized the issuance and sale of its 10.95% Notes in the aggregate
principal amount of $30,000,000.  The holders and other creditors of the
Company have heretofore agreed to waive certain defaults and events of
noncompliance by the Company, including defaults and Events of Defaults under

<PAGE>   3

the Agreement and the Holders and such other creditors also have heretofore
amended the agreements evidencing the Company's indebtedness, including the
Agreement and the 10.95% Senior Notes, which are now denominated as the
Company's 11.95% Senior Notes (the "Notes").  To effectuate amendments, and to
obtain further waivers, the Company has authorized this further amendment and
restatement of the Agreement and the Notes.  The Notes shall mature, shall bear
interest and shall otherwise be substantially in the form of Exhibit A hereto,
shall be secured as set forth in this Agreement and in the Security Documents
and payment and performance thereof shall be guaranteed as set forth in this
Agreement and in the Guaranty.  As hereinafter used in this Agreement, the term
"Notes" shall include all Notes originally issued pursuant to this Agreement
and the Other Agreements (as defined in this Section 1), and all Notes
delivered in substitution or exchange for any of said Notes pursuant to this
Agreement and said Other Agreements and, where applicable, shall include the
singular number as well as the plural.  The term "Note" shall mean one of the
Notes.  The Notes shall be issuable as registered notes to the payee or
registered assigns.  It shall not be necessary for holders to surrender their
outstanding Notes in exchange for Notes in the form of Exhibit A.  However,
prior to any transfer of any of your Notes you agree to make a notation thereon
that such Note has been amended.

                 In consideration of the waivers, amendments and further
deferrals granted by the holders of Notes in this Agreement, the Company has
authorized the issuance to the holders of Notes (if any Notes shall be
outstanding on the respective dates set forth below) of shares of Class A
Common Stock of the Company and agrees to issue to registered holders of the
Notes on the dates set forth below ("Common Stock Determination Dates"), to
each in proportion to its holding of Notes on such Common Stock Determination
Date:

                 (a)  on October 1, 1995 a number of shares of Class A Common
Stock of the Company equal to 0.271% of the total number of shares of all
classes of common stock of the Company outstanding on October 1, 1995; and

                 (b)  on April 1, 1996 a number of shares of Class A Common
Stock of the Company equal to 0.271% of the total number of shares of all
classes of common stock of the Company outstanding on April 1, 1996.

                 Certificates evidencing ownership of the shares of Class A
Common Stock to be issued to each holder of Notes on each Common Stock
Determination Date shall be delivered to such holder within three business days
following such Common Stock Determination Date.  All holders of Notes shall
have, as to shares of Class A Common Stock received pursuant hereto, the right
to have the offering and sale of such shares registered as and to the extent
set forth in the form of Registration Rights Agreement attached as Annex 3K.

                 2.  Fees.  In consideration of the waivers, amendments and
deferrals agreed to herein, the Company is paying to the holders of the Notes
on the date hereof an amount equal to .25% of the presently outstanding
principal amount of the Notes.  In addition, the Company shall pay on the dates
set forth below a cash fee equal to the percentage set forth below of the then
outstanding principal amount of the Notes:

<TABLE>
<CAPTION>
    Fixed Prepayment Date                      Principal Amount to be Prepaid
    ---------------------                      ------------------------------
         <S>                                            <C>
         July 1, 1995                                   $  449,802.57

         July 1, 1996                                   $4,048,223.09
         October 31, 1996                               $3,575,685.93
</TABLE>

provided, however, that the Company may elect by notice given pursuant to
Section 12I, not more than 45 and not less than 30 days prior to the date fixed
for prepayment (x) to defer not more than seventy-five percent (75%) of the
payments to be made on October 31, 1995 (after giving effect to payments made
pursuant to Section 4E, 4F and 4G) until December 31, 1996 when they shall be

amount so prepaid, plus accrued interest thereon to the prepayment date, plus a
Yield Maintenance Payment.  Except as provided in Section 4I, the exercise of
the right to prepay pursuant to this Section 4B shall not relieve the Company
to any extent from its obligation thereafter to make the prepayments required
by Section 4A until the Notes have been paid in full.

                 4C.  Prepayment on Change of Control.  The Company covenants
     that:

(i)  If at any time a Change of Control is expected by the Company to occur,
                 and whether or not the event which will give rise thereto is
                 permitted by Section 6E, the Company will notify the holders
                 of all of the Notes thereof not more than 45 and not less than
                 30 days prior to the date on which such Change of Control is
                 projected to occur and, upon the written demand of the holder
                 of any Note made by such holder not later than 10 days prior
                 to the date fixed for prepayment, prepay on a date which is
                 not more than 5 days after receipt of such demand and which in
                 any event must be prior to the effective time of such Change
                 of Control the entire unpaid principal amount of each Note
                 held by such holder and specified in such demand, together
                 with interest accrued thereon to the date of prepayment and
                 without premium or Yield Maintenance Payment; provided,
                 however, that if prior to the time prepayment is made the
                 particular Change of Control is cancelled and the Company
                 provides to the holders a certificate of a Responsible Officer
                 to such effect the Company shall not be required to prepay the
                 Notes.  If any such holder shall fail to make such demand
                 within the time set forth above but shall not have notified
                 the Company in writing that it does not intend to make such
                 demand, such holder shall be deemed to have demanded
                 prepayment under this Section 4C in respect of all Notes held
                 by such holder.  At the time any prepayment is made pursuant
                 to this Section 4C the Company shall also deliver to the
                 holder a certificate of a Responsible Officer stating that the
                 anticipated Change of Control is still expected to occur.
                 Promptly upon the request of any holder the Company will
                 supply all material information and respond to all questions
                 concerning any Change of Control.  Immediately upon receipt of
                 demand for payment from any holder under this Section 4C, the
                 Company will deliver a copy of such demand to all other
                 holders, to which delivery all holders do hereby consent.
                 Except as provided in Section 4I, prepayment pursuant to this
                 Section 4C shall not relieve the Company to any extent from
                 its obligation thereafter to make the prepayments required by
                 Section 4A until the Notes have been paid in full.

(ii) If a Change of Control shall occur without prior knowledge of the Company
     the Company will, as soon as possible and in any event within 5 days after
     such

                                     -7-
<PAGE>   9

Change of Control, offer to prepay the Notes together with interest to the date
of payment and without premium or Yield Maintenance Payment on a date which
shall be not less than 30 nor more than 45 days after the occurrence of such
Change of Control.  Such notice shall specify (i) that it is given pursuant to
this Section 4C, (ii) that any holder electing not to accept such offer must do
so by notice given to the Company not less than 10 days prior to the date fixed
for prepayment and failing to do so shall be deemed to have accepted such
offer, (iii) an estimate of the principal amount of the holder's Notes to be
prepaid and (iv) the accrued interest applicable to the prepayment.  If one or
more holders of Notes do not accept such offer, its or their portions of the
proceeds shall be applied by the Company, on a pro rata basis, to the
prepayment of additional Notes held by holders of Notes accepting the offer.

(iii)  If a Change of Control shall occur or be expected to occur at a time
                 which will cause a prepayment in respect thereof to be made
                 subsequent to October 31, 1993 and if any amount deferred
                 pursuant to Section 4A shall not have been paid by its
                 originally scheduled prepayment date, then any prepayment made
                 pursuant to this Section 4C shall be made at the principal
                 amount of the Notes prepaid plus interest to the date of
                 prepayment and without premium or Yield Maintenance Payment.

                 4D.  Prepayment of Notes if Business Changes.  The Company
covenants that if at any time a Change of Business is expected by the Company
to occur the Company will notify the holders of all the Notes thereof not less
than 30 days prior to the effective date of such change and, upon the written
demand of the holder of any Note made by such holder within 30 days after the
receipt of notification, prepay on a date which is not more than 60 days after
the receipt of such demand the entire unpaid principal amount of each Note held
by such holder and specified in such demand, together with interest accrued
thereon to the date of prepayment plus a Yield Maintenance Payment; provided,
however, that if prior to the time prepayment is made the particular Change of
Business is cancelled or otherwise does not occur and the Company provides to
the holders a certificate of a Responsible Officer to such effect the Company
shall not be required to prepay the Notes; and provided further that if the
Change of Business is of the type described in clauses (iv), (v), (vi) or (vii)
of Section 5I, prepayment shall be made in accordance with the provisions of
Section 5I.  If any such holder shall fail to make such demand within 30 days
after such holder's receipt of such notification, such holder shall be deemed

to have waived its right to prepayment under this Section 4D in respect of all
Notes held by such holder, but only with respect to the particular Change of
Business which caused such right of prepayment to arise hereunder and not with
respect to any subsequent or further Change of Business.  At the time any
prepayment is made pursuant to this Section 4D the Company shall also deliver
to the holder a certificate of a Responsible Officer stating that the
contemplated Change of Business has occurred or is still expected to occur.
Promptly upon the request of any holder the Company will supply all material
information and respond to all questions concerning a proposed Change of
Business.  Immediately upon receipt of demand for payment from any holder under
this Section 4D, the Company will deliver a copy of such demand to all other
holders, to which delivery all holders do hereby consent.  Except as provided
in Section 4I, prepayment pursuant to this Section 4D shall not relieve the 
Company to any extent from its obligation thereafter to make the prepayments 
required by Section 4A until the Notes have been paid in full.

                 4E.  Prepayment of Notes Upon Disposition of Assets.
In the event the Company shall, or shall permit any Subsidiary to, sell, lease,
transfer or otherwise dispose of (collectively a "Disposition") as otherwise
permitted by this Agreement, any assets (including capital stock of
Subsidiaries), described in Annex 4E-1 such Disposition shall be for cash and,
within 2 days after receipt of the Net Cash Proceeds by the Company or any
Subsidiary, the Company shall make an irrevocable offer to prepay, pro rata, on
a date specified in such offer which shall be not less than 5 nor more than 7
days after the date of receipt of such Net Cash Proceeds, the Pro Rata Share
attributable to the Notes of 50% of the Net Cash Proceeds at a price equal to
100% of the unpaid principal amount of the Notes so prepaid plus interest
accrued to the date of prepayment.  In the event the Company shall, or shall
permit any Subsidiary to, make a Disposition as otherwise permitted by this
Agreement, of any assets (including capital stock of Subsidiaries), described
in Annex 4E-2, such Disposition shall be for cash and, within 2 days after
receipt of the Net Cash Proceeds by the Company or any Subsidiary, the Company
shall make an irrevocable offer to prepay, pro rata, on a date specified in
such offer which shall be not less than 5 nor more than 7 days after the date
of receipt of such Net Cash Proceeds, the Pro Rata Share attributable to the
Notes of 100% of the Net Cash Proceeds at a price equal to 100% of the unpaid
principal amount of the Notes so prepaid plus interest accrued to the date of
prepayment.  The amount of each prepayment applied pursuant to this Section 4E
to the prepayment of Notes shall be applied first in reduction of the Fixed
Prepayment to be made on July 1, 1995 and then proportionately in reduction of

                                     -9-
<PAGE>   11

each subsequent Fixed Prepayment to be made subsequent to the date of
prepayment.  Such notice shall be certified by an authorized officer of the
Company and shall specify (i) that it is given pursuant to this Section 4E,
(ii) that any holder electing not to accept such offer must do so by notice
given to the Company not later than the day prior to the date fixed for
prepayment and failing to do so shall be deemed to have accepted, (iii) an
estimate of the principal amount of the holder's Notes to be prepaid and
showing the calculations used to derive that amount and (iv) the accrued
interest applicable to the prepayment.  If one or more holders of Notes do not
accept such offer, its or their portions of the proceeds shall be applied by
the Company, on a pro rata basis, to the prepayment of additional Notes held by
holders of Notes accepting the offer.  Notwithstanding the foregoing, the
Company may make Dispositions of isolated assets resulting in net cash proceeds
to the Company or its Subsidiaries of not in excess of $1,000,000 per annum and
such Dispositions shall not be subject to the provisions of this Section.

                 4F.  Prepayment From Excess Unrestricted Funds.  If during any
month, the Company shall have had Average Daily Unrestricted Cash Balances in
excess of $40,000,000, the Company shall, concurrently with delivery of the
certificate required by Section 5A(iv), make an irrevocable offer to prepay,
pro rata, on a date specified in such offer which shall be not less than 5 nor
more than 7 days after the date of delivery of such certificate, the Pro Rata
Share attributable to the Notes of such excess over $40,000,000 (the "Excess
Cash") at a price equal to 100% of the unpaid principal amount of the Notes so
prepaid plus interest accrued to the date of prepayment; the amount of such
prepayment applied to the prepayment of Notes shall be applied first in
reduction of the Fixed Prepayment to be made on July 1, 1995 and then
proportionately in reduction of each subsequent Fixed Prepayment to be made
subsequent to the date of prepayment.  Such notice shall specify (i) that it is
given pursuant to this Section 4F, (ii) that any holder electing not to accept
such offer must do so by notice given to the Company not later than the day
preceding the date fixed for prepayment and failing to do so shall be deemed to
have accepted, (iii) an estimate of the principal amount of the holder's Notes
to be prepaid and the calculations used to derive that amount and (iv) the
accrued interest applicable to the prepayment.  If one or more holders of Notes
do not accept such offer, its or their portions of the proceeds shall be
applied by the Company, on a pro rata basis, to the prepayment of additional
Notes held by holders of Notes accepting the offer.

                 4G.  Other Pro Rata Prepayments.  In the event that there
shall at any time be any reduction in the principal amount of notes outstanding
pursuant to the 1990 Note Agreement or in the amount of the letter-of-credit
obligations of banks participating in the Bank Agreement (other than a pro rata
reduction resulting from payments corresponding to a Pro Rata Share received
pursuant to Section 4E or Section 4F) the Company shall, within two days of the
earlier of the date of such reduction or the date on which the Company shall
have committed itself to the course of conduct resulting in such reduction,
make an irrevocable offer to prepay such amount of Notes as shall be necessary
to maintain the Pro Rata Share of the Notes, as a percentage of all Waived
Senior Debt, at 6.77%.  The offer to be made shall specify (i) that it is given
pursuant to this Section 4G, (ii) that any holder electing not to accept such
offer must do so by notice given to the Company not less than five days prior
to the date fixed for prepayment (which date shall be not fewer than 10 nor
more than 30 days from the date of such offer) and failing to do so shall be
deemed to have accepted, (iii) an estimate of the principal amount of the
holder's Notes to be prepaid and the calculations used to derive that amount,
(iv) the accrued interest applicable to the prepayment and (v) if any holder of
other Waived Senior Debt shall have received any premium or other payment
(other than accrued interest or letter-of-credit fees) additional to the amount
of the reduction, the Yield Maintenance Payment which shall in such event be
payable.  Any prepayment made pursuant to this Section 4G shall be applied
proportionately in reduction of each subsequent Fixed Prepayment.

                 4H.  Notice of Optional Prepayment of Notes.  The Company
shall give you written notice of each optional prepayment of the Notes pursuant
to Section 4B not less than 30 days prior to the prepayment date, specifying
such prepayment date and the principal amount of the Notes to be prepaid on
such date and Yield Maintenance Payment or other premium, if any, in respect of
such prepayment.  If any Note shall have been transferred to another holder
pursuant to Section 12D and such holder shall have designated in writing the
address to which notices with respect to such Note shall be mailed, such notice
of prepayment shall also be given to such holder at such designated address.
Notice of prepayment having been given as aforesaid, the principal amount of
the Notes specified in such notice, together with interest thereon to the date
of prepayment, and the premium, if any, herein provided, shall become due and
payable on the prepayment date.

<PAGE>   13

                 4I.  Allocation of Partial Prepayments of Notes.  Upon any
partial prepayment of the Notes pursuant to Section 4A, 4B, 4E, 4F, 4G or 5I,
the amount so prepaid shall be allocated to all Notes at the time outstanding
in proportion to the unpaid principal amounts thereof.  Subject to Section 12A,
upon any partial prepayment of any Note, such Note shall, at the option of the
holder thereof, be either (i) surrendered to the Company in exchange for a new
Note in a principal amount equal to the principal amount remaining unpaid on
the Note surrendered, or (ii) made available to the Company at your principal
office for notation thereon of the portion of the principal so prepaid.  Any
prepayments made pursuant to Section 4C or 4D  will proportionately reduce the
remaining fixed prepayments under Section 4A.  Any prepayments made pursuant to
Section 4E, 4F, 4G or 5I shall be applied to the remaining Fixed Prepayments in
the manner set forth in those Sections.  Any prepayment made pursuant to

              the minimum funding standards established under Section 412 of
              the Code for a Plan,
         
         the Company covenants that it will furnish to you (a) a copy of any
         notice received, request or petition filed, and agreement entered 
         into, (b) the most recent Annual Report (Form 5500 Series) and 
         attachment thereto for the Plan, (c) the most recent actuarial report
         for the Plan, (d) any notice, return or materials required to be filed
         with the Internal Revenue Service, the PBGC or Plan participants and 
         beneficiaries in connection with the event, action or filing, and (e)
         a written statement of the President, Treasurer or chief financial 
         officer of the Company describing the event or the action taken and 
         the reasons therefor.

                          5C.  Corporate Existence; Maintenance of Office.  (i)
     The Company will maintain and preserve, and will cause each Subsidiary to
     maintain and preserve, its corporate existence and right to carry on its
     business and use, and cause each Subsidiary to use, its best efforts to

                                     -19-

    maintain, preserve, renew and extend all of its rights, powers,
    privileges and franchises necessary to the proper conduct of its business;
    provided, however, that the foregoing shall not prevent any transaction
    permitted by Section 6E and provided further, that nothing in this Section
    5C shall prevent the termination of the corporate existence of any
    Subsidiary if, in the opinion of the Board of Directors of the Company,
    such termination is in the best interests of the Company, is not
    disadvantageous to holders of the Notes and is not otherwise prohibited by
    this Agreement.

                          (ii)  The Company covenants that it will maintain an
    office or agency in Pittsburgh, Pennsylvania, or in such other place in
    the continental United States as the Company may from time to time specify
    in writing, where notices, presentations and demands to or upon the Company
    in respect of the Notes may be given or made.

                          5D.  Compliance with Laws.  (i)  The Company will
    comply, and will cause each Subsidiary to comply, with all laws, rules
    and regulations, (including, without limitation, laws and regulations
    relating to equal employment opportunities and Environmental Laws) relating
    to its or their respective businesses, other than laws, rules and
    regulations the failure to comply with which or the sanctions and penalties
    resulting therefrom, individually or in the aggregate, would not have a
    material adverse effect on the business, properties, operations, or
    condition, financial or otherwise, of the Company and its Subsidiaries
    taken as a whole, and would not result in the creation of a Lien which, if
    incurred in the ordinary course of business, would not be permitted by
    Section 6I on any of the property of the Company or any Subsidiary;
    provided, however, that the Company and its Subsidiaries shall not be
    required to comply with laws, rules and regulations the validity or
    applicability of which are being contested in good faith and by appropriate
    proceedings and as to which the Company has established adequate reserves
    on its books.

                          (ii)  Promptly upon the occurrence thereof, the
    Company will give you and each other Institutional Holder written
    notice of the institution of any proceedings against, or the receipt of
    notice of potential liability or responsibility of, the Company or any
    Subsidiary for violation, or the alleged violation, of any Federal, state
    or local law, rule or regulation, including but not limited to, regulations
    promulgated under any Environmental Law, which violation could give rise to
    a material liability of the Company and its Subsidiaries taken as a whole.

                                     -20-
<PAGE>   22


                          (iii)  The Company will pay and discharge when due,
    and will cause each Subsidiary to pay and discharge when due, all
    taxes, assessments and governmental charges or levies imposed upon it or
    its property or assets, or upon properties leased by it (but only to the
    extent required to do so by the applicable lease), other than taxes which
    individually and in the aggregate are not material in amount and the
    non-payment of which would not have a material adverse affect on the
    business, properties, operations or condition, financial or otherwise, of
    the Company and its Subsidiaries taken as a whole, prior to the date on
    which penalties attach thereto, and all lawful claims which, if unpaid,
    might become a Lien upon its property or assets provided that neither the
    Company nor any Subsidiary shall be required to pay any such tax,
    assessment, charge, levy or claim, the payment of which is being contested
    in good faith and by proper proceedings that will stay the forfeiture of
    sale of any property and with respect to which adequate reserves are
    maintained in accordance with generally accepted accounting principles.

                          5E.  Use of Proceeds.  No part of the proceeds from
    the sale of the Notes will be used, whether directly or indirectly, and
    whether immediately, incidentally or ultimately (i) to purchase or carry
    margin stock or to extend credit to others for the purpose of purchasing or
    carrying margin stock, or to refund indebtedness originally incurred for
    such purpose, or (ii) for any purpose which entails a violation of, or
    which is inconsistent with, the provisions of the Regulations of the Board
    of Governors of the Federal Reserve System, including without limitation
    Regulations G, U, T or X thereof.

                          5F.  Insurance.  The Company will insure and keep
    insured at all times all of its properties and all of its Subsidiaries'
    properties which are of an insurable nature and of the character usually
    insured by companies operating similar properties, against loss or damage
    by fire and from other causes customarily insured against by companies
    engaged in similar businesses in such amounts as are usually insured
    against by such companies.  The Company also will maintain for itself and
    its Subsidiaries at all times adequate insurance against loss or damage
    from such hazards and risks to the person and property of others as are
    usually insured against by companies operating properties similar to the
    properties of the Company and its

                                     -21-
<PAGE>   23

    Subsidiaries.  All such insurance (other than permitted self-insurance)
    shall be carried with financially sound and reputable insurers accorded a
    rating of A- and VII or better by A.M. Best Company, Inc., unless any such
    insurance is not available on commercially reasonable terms from any
    insurer so rated, in which case it shall be carried by a financially sound
    and reputable insurer which in the opinion of the Company most closely
    approximates the criteria necessary to obtain such rating.  The Company may
    self-insure (i) without limitation to the extent such self-insurance is
    fully collateralized by cash or letters of credit and (ii) otherwise in
    amounts which, in the aggregate, do not at any time exceed 13% of
    Consolidated Tangible Net Worth.  At no time will the Company's and its
    Subsidiaries' insurance be less than that carried on the date hereof unless
    such insurance becomes unavailable.  A summary of insurance presently in
    force, including self-insurance and deductibles, is contained in the
    attached Annex 5F.

                          5G.  Inspection of Property, Books and Records.  The
    Company covenants that it will permit, and will cause each of its
    Subsidiaries to permit, any representative designated in writing by you or
    any other Institutional Holder which is not a Competitor to visit and
    inspect any of its properties, to examine its corporate, financial and
    operating records and make copies thereof or abstracts therefrom, and to
    discuss its affairs, finances and accounts with its directors, officers,
    employees and independent accountants, all at such reasonable times, upon
    reasonable notice and as often as may reasonably be desired.

                          5H.  Covenant to Secure Notes.  The Company covenants
    that, if the Company or any Subsidiary shall create, assume or suffer
    to exist any Lien upon any of its property or assets not subject to the
    prior Lien of the Security Documents, whether now owned or hereafter
    acquired, other than Liens permitted under Section 6I hereof, it will make
    or cause to be made effective provision whereby the Notes will be secured
    by such Lien equally and ratably with any and all other Debt thereby
    secured by the same property or assets, in each case as long as any such
    other Debt shall be so secured, that the creation of any such security
    shall not in any way alter the rights of the holders of the Notes to
    enforce the provisions of Section 6I hereof or of the Security Documents or
    the Guaranty.

                          5I.  Conduct of Business.

                          (i)  Subject to paragraphs (ii) through (vii) hereof,
         the Company will, and will cause each Subsidiary to, engage
         only in the business of (a) Non-Hazardous Waste management (including
         recycling and composting), (b) incineration and disposal of
         Non-Hazardous Wastes, (c) transportation of Non-Hazardous Wastes and
         (d) operations ancillary to the foregoing.

                          (ii)  Without reference to paragraphs (iii) through
         (vii) of this Section 5I, in the event of the acquisition by
         the Company or a Subsidiary of a business an incidental (less than 25%
         of the assets and revenues of such business and less than 5% of the
         consolidated revenues of the Company and its Subsidiaries on a
         pro-forma basis) portion of which is not described in section
         5I(i)(a)-(d) hereof, the Company shall have 180 days from  the date of
         such acquisition to discontinue or dispose of such noncomplying 
         activities before it shall be deemed to be in violation of this
         Section 5I or  a Change of Business shall be deemed to have occurred. 
         The Company shall  give prompt written notice, but in any event within
         10 days of each event  specified in this paragraph (ii) to each holder
         of Notes of (i) any such  acquisition, specifying in reasonable detail
         the noncomplying activities and  (ii) the discontinuance or
         disposition of such noncomplying activities.  This  paragraph (ii)
         shall not be available for the acquisition of any business a  greater
         than incidental portion of which violates this Section 5I.

                          (iii)  The reclassification to hazardous (a
         "Reclassification"), by law or by any regulatory authority, of
         Non-Hazardous Waste ("Reclassified Waste") being managed (which term
         shall be deemed to include incineration, disposal, storage and
         transportation) by the Company or any of its Subsidiaries or
         contracted to be managed by the Company or any of its Subsidiaries or
         with respect to which the Company or any of its Subsidiaries has been
         issued a permit to manage by a regulatory authority during the term of
         this Agreement shall not be deemed to be a Change of Business or a
         violation of this Section 5I if, immediately following such

                                     -23-
<PAGE>   25

         Reclassification, (x) the Company's handling of such
         Reclassified Waste complies in all material respects with all
         applicable permits, laws and regulations and (y) the consolidated
         revenues produced from the management of Reclassified Waste shall not
         have constituted more than 5% of the Company's consolidated revenues
         for the twelve months ended as of the Company's most recently
         completed fiscal quarter prior to the effective date of the
         Reclassification.  The Company shall give written notice of a
         Reclassification within 10 days of such Reclassification.

                          (iv)  If, as a result of a Reclassification, the
         consolidated revenues produced from the management of
         Reclassified Waste exceed 5% of the Company's consolidated revenues
         for the twelve months ended as of the end of the most recently
         completed fiscal quarter prior to the effective date of the
         Reclassification, the Company shall, within 30 days after the
         effective date of such Reclassification, give written notice to each
         holder of a Note of such fact, specifying in reasonable detail the
         nature of such Reclassification and the amount and percentage of
         consolidated revenues produced by the management of Reclassified
         Waste.  Such notice shall contain the written offer of the Company to
         prepay, on a date specified in such notice which shall be a business
         day not less than 160 nor more than 180 calendar days after the
         effective date of such Reclassification, the entire principal amount
         of the Notes held by each holder at a price equal to 100% of the
         principal amount thereof plus accrued interest to the date of
         prepayment and shall state that notice of acceptance of the Company's
         offer to prepay under this Section 5J(iv) must be delivered to the
         Company within 115 calendar days after receipt of the Company's
         notice.  Any holder may revoke its acceptance of the Company's offer
         by written notice to such effect delivered to the Company not less
         than 15 days prior to the date fixed for prepayment.  In the event the
         Company discontinues or disposes of a sufficient portion of the
         Reclassified Waste management activities so that, after giving effect
         thereto, the consolidated revenues produced from management of
         Reclassified Waste would be less than 5% of the Company's consolidated
         revenues for the period specified in the first sentence of this
         paragraph (iv), the Company may revoke its prepayment offer by written
         notice to each holder of Notes not less than 5 days prior to the
         payment date specified in the offer, which notice shall demonstrate to
         the satisfaction of each holder the effectiveness of the actions taken
         and set forth the calculations of consolidated revenues, and the
         Company's obligation to prepay the Notes shall terminate.

                          (v)  If, as a result of a Reclassification, the
         consolidated revenues produced from the management of Reclassified
         Waste exceed 25% of the Company's consolidated revenues for the twelve
         months ended as of the end of the most recently completed fiscal 
         quarter prior to the effective date of the Reclassification, the 
         Company shall, within 30 days after the effective date of such 
         Reclassification, give written notice to each holder of a Note of 
         such fact, specifying in reasonable detail the nature of such 
         Reclassification and the amount and percentage of consolidated 
         revenues produced by the Company and its Subsidiaries from the 
         management of Reclassified Waste.  Such notice shall contain the 
         written offer of the Company to prepay, on a date specified in
         such notice which shall be a business day not less than 160 nor more 
         than 180 calendar days after the effective date of such 
         Reclassification, the entire principal amount of the Notes held by 
         each holder at a price equal to 100% of the principal amount thereof
         plus accrued interest to the date of prepayment plus a Yield 
         Maintenance Payment and shall state that notice of acceptance of the 
         Company's offer to prepay under this Section 5I(v) must be delivered 
         to the Company within 115 calendar days after receipt of the Company's
         notice.  Any holder may revoke its acceptance of the Company's offer 
         by written notice to such effect delivered to the Company not less 
         than 15 days prior to the date fixed for prepayment.  In the event
         the Company discontinues or disposes of a sufficient portion of the
         Reclassified Waste management activities so that after giving effect
         thereto, the revenues produced from management of the Reclassified 
         Waste would be less than 5% of the Company's consolidated revenues 
         for the period specified in the first sentence of this paragraph (e),
         the Company may revoke its prepayment offer by written notice to each
         holder of Notes not less than 5 days prior to the payment date 
         specified in the offer, which notice shall demonstrate to the 
         satisfaction of each holder the effectiveness of the actions taken
         and set forth the calculations of consolidated revenues, and the
         Company's obligation to prepay the Notes shall terminate.

                          (vi)  If as of the end of any fiscal quarter ending
         after a Reclassification, the consolidated revenues produced
         from the management of Reclassified Waste exceed 5% of the Company's
         consolidated revenues for the twelve months then ended, the Company
         shall, not later than 30 days after the end of such quarter, give
         written notice to each holder of a Note of such fact, specifying in
         reasonable detail the amount and percentage of consolidated revenues
         produced from the management of Reclassified Waste.  Such notice shall
         contain the written, irrevocable offer of the Company to prepay, on a
         date specified in such notice which shall be a business day not less
         than 160 nor more than 180 calendar days after the end of such
         quarter, the entire principal amount of the Notes held by each holder
         at a price equal to 100% of the principal amount thereof plus accrued
         interest to the date of prepayment and shall state that notice of
         acceptance of the Company's offer to prepay under this Section 5J(vi)
         must be delivered to the Company within 115 calendar days after
         receipt of the Company's notice.  Any holder may revoke its acceptance
         of the Company's offer by written notice to such effect delivered to
         the Company not less than 15 days prior to the date fixed for
         prepayment.  In the event the Company disposes of or discontinues all
         Reclassified Waste management activities within 150 days after the end
         of the fiscal quarter referred to in the first sentence of this
         paragraph, the Company may revoke its prepayment offer by written
         notice to each holder of Notes not less than 50 days prior to the
         payment date specified in the offer, which notice shall demonstrate to
         the satisfaction of each holder the effectiveness of the actions
         taken, and the Company's obligation to prepay the Notes shall
         terminate.

                          (vii)  If as of the end of any fiscal quarter ending
         after a Reclassification, the consolidated revenues produced
         from the management of Reclassified Waste exceed 25% of the Company's
         consolidated revenues for the twelve months then ended, the Company
         shall not later than 30 days after the end of such quarter, give
         written notice to each holder of a Note of such fact, specifying in
         reasonable detail the amount and percentage of consolidated revenues
         produced from the management of Reclassified Waste.  Such notice shall
         contain the written, irrevocable offer of the Company to prepay, on a
         date specified in such notice which 

                                     -26-
<PAGE>   28
    
         shall be a business day not less than 160 nor more than 180
         calendar days after the end of such quarter, the entire principal
         amount of the Notes held by each holder at a price equal to 100% and
         the principal amount thereof plus accrued interest to the date of
         prepayment plus a Yield Maintenance Payment and shall state that
         notice of acceptance of the Company's offer to prepay under this
         Section 5I(vii) must be delivered to the Company within 115 calendar
         days after receipt of the Company's notice.  Any holder may revoke its
         acceptance of the Company's offer by written notice to such effect
         delivered to the Company not less than 15 days prior to the date fixed
         for prepayment.  In the event the Company disposes or discontinues all
         Reclassified Waste management activities within 150 days after the end
         of the fiscal quarter referred to in the first sentence of this
         paragraph, the Company may revoke its prepayment offer by written
         notice to each holder of Notes not less than 50 days prior to the
         payment date specified in the offer, which notice shall demonstrate to
         the satisfaction of each holder the effectiveness of the actions
         taken, and the Company's obligation to prepay the Notes shall
         terminate.

                          (viii)  The Company will maintain, preserve and keep,
         and will cause each Subsidiary to maintain, preserve and keep,
         its properties (whether owned in fee or a leasehold interest) in good
         repair and working order, ordinary wear and tear excepted, and from
         time to time will make all necessary repairs, replacements, renewals
         and additions.

                          (ix)  Nothing in this Section 5I shall prohibit any
         consolidation, merger or sale that is not prohibited by Section
         6E; provided, however, that if the Company consolidates or merges with
         or acquires another entity permitted by Section 6E and such entity is
         engaged in businesses which are not allowed by this Section 5I the
         Company shall have six months from the date of such transaction to
         dispose of or terminate such unallowed operations before a Change of
         Business shall be deemed to have occurred; provided, further that in
         no case will the Company consolidate or merge with or acquire an
         entity which is engaged in the management of hazardous waste.  The
         reclassification by any regulatory authority of waste materials being
         managed by the Company or any of its Subsidiaries or contracted to be
         managed by the Company or any of its Subsidiaries or with respect to
         which the Company or any of its Subsidiaries has been issued a permit
         to manage by a regulatory authority during the term of this Agreement
         from Non-Hazardous Waste to hazardous waste shall not be deemed

                                     -27-
<PAGE>   29

         a Change of Business so long as (a) the Company's management of
         such material complies in all material respects with all applicable
         permits, laws and regulations and (b) a Responsible Officer does not,
         as of the date of this Agreement, have knowledge that such
         Non-Hazardous Waste is scheduled for reclassification as a result of
         completed legislative or regulatory action or pending or proposed
         federal or state legislative or regulatory action notice or
         description of which has been published in the Congressional Record or
         the Federal Register, in the case of federal action, or the analogous
         state publications, in the case of state action.

                          (x)  The Company covenants that from and after the
         date hereof neither it nor any Subsidiary will intentionally
         enter the  business of hazardous waste management (as defined by
         federal and state  statutes and regulatory authorities).

                 5J.  Private Letter Rating.  The Company shall cooperate with
you and use its best efforts to obtain at its expense a private letter rating
on the notes from either Moody's Investor Services, Inc. or Standard & Poor's
Corporation.

                 6.  Negative Covenants.  All covenants contained herein shall
be given independent effect so that if a particular action or condition is not

                 (i)  The Company represents and warrants that the Security
    Documents are in full force and effect and create, in favor of the
    secured parties named therein a valid and effective first priority Lien on
    the pledged assets, subject only to (i) compliance with applicable
    recording and other perfection laws and (ii) to the terms of an
    Intercreditor Agreement among you, the Reliance Group and the other secured
    parties which are parties thereto, dated February 26, 1993.

                 (ii)  Each Guarantor represents and warrants that the Guaranty
    has been duly authorized, executed and delivered and constitutes the valid
    and binding obligation of such Guarantor, enforceable in accordance with 
    its terms.

                 10B.  Organization and Qualification.  Each Guarantor
represents and warrants that it is a corporation duly organized and in good
standing under the laws of the jurisdiction of its incorporation and is duly
qualified to do business in every other jurisdiction in which the failure so to
qualify would have a material adverse effect on such Guarantor.

                 10C.  Guaranty.  Each Guarantor hereby irrevocably and
unconditionally guarantees, as and for its own debt, until final and
indefeasible payment has been made, the due and punctual payment of the
principal and interest and Yield Maintenance Payment, if any, on all Notes at
any time outstanding and the due and punctual payment of all moneys payable,
and all other indebtedness owing, by the Company under the Agreements
(collectively, the "Guarantied Obligations") and the due and punctual payment
of all monies payable by the Company under the Registration Rights Agreement in
each case when and as the same shall become due and payable, whether at
maturity, pursuant to mandatory or optional prepayment, by acceleration or
otherwise, all in accordance with the terms and provisions of the Guaranty
attached as Exhibit B hereto; it being the intent of the Guarantors that the
guaranty set forth in this Section 10 shall be a guaranty of payment and not a
guaranty of collection.

                 10D.  Performance by Guarantors.  Each Guarantor agrees that
its liability under this Section 10 and under the Guaranty shall be immediate
and shall not be contingent upon the exercise or enforcement by any holder of
Notes of whatever remedies it may have against the Company or any other
guarantor or the enforcement of any Lien or realization upon any security such
holder may at any time possess or have available for its benefit.

                                   -46-
<PAGE>   48

                 The Guaranty set forth in this Section 10 and in the Guaranty
is a primary and original joint and several obligation of the Guarantors and is
an absolute, unconditional, continuing and irrevocable guaranty of payment and
shall remain in full force and effect without respect to future changes in
conditions, including change of law, or any invalidity or irregularity with
respect to the issuance of any obligations (including, without limitation, any
of the Notes) of the Company, or with respect to the execution and delivery of
any agreement (including, without limitation, any of the Agreements, the
Registration Rights Agreement or the Notes) between the Company and any one or
more of the holders of Notes, or with respect to the genuineness, validity,
regularity or enforceability of any of the Guarantied Obligations.

                 10E.  No Election.  Each holder of Notes shall (individually
or collectively with the other holders) have the right to seek recourse against
any one or more of the Guarantors to the full extent provided for in this
Section 10, and against the Company to the full extent provided for in the
Notes and the Agreements.  No election to proceed in one form of action or
proceeding, or against any party, or on any obligation, shall constitute a
waiver of the right of such holder of Notes, to proceed in any other form of
action or proceeding or against other parties unless such holder of Notes has
expressly waived such right in writing.  Specifically, but without limiting the
generality of the foregoing, no action or proceeding by any holder of Notes
against the Company under any document or instrument evidencing Guarantied
Obligations shall serve to diminish the liability of any Guarantor under this
Section 10 except to the extent that such holder finally and unconditionally
shall have realized payment by such action or proceeding, notwithstanding the
effect of any such action or proceeding upon such Guarantor's right of
subrogation against the Company.  Each Guarantor is fully aware of the
financial condition of the Company.  Each Guarantor is executing and delivering
this guaranty based solely upon its own independent investigation and in no
part upon any representation or statement of any one or more of the holders of
Notes with respect thereto.  Each Guarantor is in a position to obtain, and
hereby assumes full responsibility for obtaining, any additional information
concerning the financial condition of the Company as the Guarantor may deem
material to its obligations hereunder, and the Guarantor is not relying upon,
nor expecting, any holder of Notes to furnish it any information concerning the
financial condition of the Company.

                 10F.  Continuing Guaranty.  The Guarantors' obligations in
this Section 10 are continuing obligations and shall apply to all Guarantied
Obligations whenever arising.

                 10G.  Inspection.  Each Guarantor shall permit the
representatives of each Institutional Holder (at the expense of such Person
unless a Default or Event of Default shall have occurred and then at the
expense of the Company), to visit and inspect any of the properties of the
Guarantor or any of its Subsidiaries, to examine all their respective books of
account, records, reports and other papers, to make copies and extracts
therefrom, and to discuss their respective affairs, finances and accounts with
their respective officers, employees and independent public accountants (and by
this provision each Guarantor authorizes said accountants to discuss its
finances and affairs and the finances and affairs of its Subsidiaries) all at
such reasonable times and as often as may be reasonably requested.

                 10H.  Maintenance of Properties and Corporate Existence.

                 (i)  Property -- maintain its property in good condition,
       ordinary wear and tear excepted, and make all necessary renewals,
       replacements, additions, betterments and improvements thereto;

                 (ii)  Financial Records -- keep true books of records and
       accounts in which full and correct entries shall be made of all its 
       business transactions and which will permit the provision of accurate 
       and complete financial statements in accordance with GAAP;

                 (iii)  Corporate Existence and Rights -- do or cause to be
       done all things necessary to preserve and keep in full force and effect
       its corporate existence, rights (charter and statutory) and franchises;
       and

                 (iv)  Compliance with Law -- not be in violation of any law,
       ordinance or governmental rule or regulation to which it is subject and
       not fail to obtain any license, certificate, permit, franchise or other
       governmental authorization necessary to the ownership of its properties
       or to the conduct of its business if such violation or failure to obtain
       could be reasonably expected to have a material adverse effect on such 
       Guarantor.

                 10I.  Merger; Acquisition.  No Guarantor will merge into,
consolidate with, or sell, lease, transfer or otherwise dispose of all or
substantially all of its property to, any other Person or permit any other
Person to consolidate with or merge into it (except that the Company may merge
with a Guarantor if the Company is the surviving corporation); provided that
the foregoing restriction is subject to the provisions of Section 4E and does
not apply to the merger or consolidation of a Guarantor with another
corporation, if:

                 (i)  the corporation that results from such merger or
    consolidation or that purchases, leases, or acquires all or substantially 
    all of such Property (the "Guarantor Surviving Corporation") is organized 
    under the laws of the United States of America or any jurisdiction thereof;

                 (ii)  the due and punctual payment of all the Guarantied
    Obligations and all other obligations of the Guarantor hereunder and the
    punctual performance and observance of all the covenants herein to be 
    performed or observed by the Guarantor are expressly and effectively
    assumed by the Guarantor Surviving Corporation pursuant to such
    agreements and instruments as shall be approved by the Majority of Holders,
    and the Guarantor will cause to be delivered to each holder of Notes an
    opinion of independent counsel to the effect that (i) such agreements and
    instruments are enforceable in accordance with their terms and (ii) no
    taxable event or consequence will result to any holder of Notes solely by
    virtue of such merger, consolidation, purchase, lease or acquisition and
    the assumption by the Guarantor Surviving Corporation of the obligations of
    the Guarantor hereunder; and
              
                 (iii)  immediately prior to, and immediately after the
    consummation of the transaction, and after giving effect thereto, no 
    Default or Event of Default exists or would exist under any provision of 
    this Agreement.

                 10J.  Additional Guarantors.  The Company and each Guarantor
covenants and agrees that no Subsidiary of the Company shall be created or
acquired, and no investment shall be made in any entity which is or becomes a

                                 -49-
<PAGE>   51

Subsidiary of the Company or any Guarantor unless such entity shall, at the
time it becomes a Subsidiary of the Company or of a Guarantor, as the case may
be, deliver to each holder of Notes a written assumption of all of the duties

<PAGE>   64

any Note, you will make a notation thereon of all principal payments 
previously made thereon and of the date to which interest thereon has been

of such Note.  At the election of any subsequent holder of any Note that is

Note as you have made in this Section 12A, the Company will make payments of 
principal and interest, and premium, if any, in respect thereof, to a place

liabilities, losses, damages, costs and expenses of any kind (including,
without limitation, the fees and expenses of your special counsel in connection
with any investigative, administrative or judicial proceeding, whether or not
you shall be designated a party thereto) which may be incurred by you, relating

contemplated hereby, except such as may be incurred by you due to any violation

                                     -63-
<PAGE>   65

all Notes at the time outstanding, no amendment to this Agreement shall extend
the maturity of any Note, or change the amount of principal of any Note, or
reduce the portion of the principal amount of Notes required with respect to
any consent, or reduce the rate or change the time of payment of interest or
reduce any premium payable with respect to any Note.  Each holder of any Note
at the time or thereafter outstanding shall be bound by any consent authorized
by this Section 12C, whether or not such Note shall have been marked to
indicate such consent, but any Note issued thereafter shall bear a notation
referring to any such consent.  The Company covenants that it (i) will not
solicit any modification, waiver or consent to any Agreement or Note without
making the same solicitation to each holder of any Note then outstanding, (ii)
will not pay any compensation or other remuneration, or make any accommodation
for the benefit of any holder, in connection with any requested modification,
amendment or waiver of any Agreement or Note without making the same payment or
accommodation in favor of each other holder of any Note then outstanding and
(iii) will provide copies to each holder of any Note then outstanding of all
modifications, amendments or waivers to any Agreement or Note promptly upon
adoption or approval thereof.

                 12D.  Form, Registration, Transfer and Exchange of  Notes.
The Notes are issuable as registered notes in the denominations of $500,000 and
any integral multiple of $500,000.  The Company shall keep at its principal
office a register in which the Company shall provide for the registration and
transfer of Notes.  Upon surrender for registration of transfer of any Note at
the office of the Company, the Company shall, at its expense, execute and
deliver one or more new Notes of a like aggregate principal amount registered
in the name of the designated transferee or transferees.  At the option of the
holder of any Note, such Note may be exchanged for other Notes of any
authorized denominations, of a like aggregate principal amount, upon surrender
of the Note to be exchanged at the office of the Company.  Each such new Note
shall be payable to such Person as such holder may request.  Whenever any Note
is so surrendered for exchange, the Company shall, at its expense, execute and
deliver the Note or Notes that the holder of such surrendered Note is entitled
to receive.  Every Note presented or surrendered for registration of transfer
shall be duly endorsed, or be accompanied by a written instrument of transfer
duly executed, by the holder of such Note or his attorney duly authorized in
writing.  Any Note or Notes issued in exchange for any Note or upon transfer
thereof shall carry the rights to unpaid interest and interest to accrue which
were carried by the Note so exchanged or transferred, and neither gain nor loss
of interest shall result from any such transfer or exchange.  No Note shall be


                                   -64-
<PAGE>   66

sold by any holder unless such holder first offers such Note to the Company for
purchase.  Upon receipt of notice from a holder that it desires to sell a Note
the Company will have five business days to make an offer to purchase such
Note, which offer shall include the payment of accrued interest on such Note to
the date of closing (such offer by the Company being hereinafter referred to as
the "Initial Offer").  At the time of the Initial Offer the holder shall
calculate the "Initial Offer Spread" which shall be the spread between the
yield to maturity implicit in the Initial Offer and that of the United States
Treasury Securities having a constant maturity equal to the remaining weighted
average life to final maturity of the principal of such Note.  The holder shall
have five business days from the date the Initial Offer is made by the Company
to accept or reject the Initial Offer.  If the holder accepts the Initial
Offer, the Company shall have 45 days to consummate the purchase of the Note.
If the Company does not consummate the purchase within that period the holder
shall be entitled to sell such Note without regard to the Company's purchase
right set forth in this Section 12D, and the Company shall indemnify the holder
for any loss it suffers as a consequence of the Company's failure to consummate
such purchase.  Such indemnity shall be in an amount equal to the difference
between the Initial Offer price and the price actually received by the holder
for such Note, if less than the Initial Offer, plus any out-of-pocket expenses
incurred by the holder as a result of the Company's failure to consummate the
purchase.  If the holder rejects the Initial Offer the holder may transfer such
Note to another institutional investor not more than six months after the
Initial Offer so long as the spread between the yield to maturity implicit in
the sale price and that of the United States Treasury Securities having a
constant maturity equal to the remaining weighted average life to final
maturity of the principal of such Note is less than the Initial Offer Spread.
If a sale is made by a holder pursuant to the immediately preceding sentence
the holder will deliver notice of such sale to the Company, which notice will
include the sale price at which the transaction occurred.  If a holder desires
to sell a Note more than six months after an Initial Offer the Company shall
again be first offered the opportunity to purchase such Note before a sale is
made.  For purposes of this Section 12D, the term "institutional investor"
shall mean any of the following: bank or other financial institution; savings
and loan association; trust company; insurance company; broker or dealer;
pension or profit sharing plan or trust; investment company; public or private
institution which has received exempt status under Section 501(c)(3) of the
Code; foundation, trust or endowment fund exempt from taxation under the Code;
association engaged as a substantial part of its business or operations in
purchasing or holding securities; trust in respect of which a financial
institution is trustee or co-trustee; or any entity whose security holders
consist solely of institutional investors.

                 12E.  Persons Deemed Owners.  Prior to due presentment for
registration of transfer, the Company may treat the Person in whose name any
Note is registered as the owner and holder of such Note for the purpose of
receiving payment of principal of, premium, if any, and interest on such Note
and for all other purposes whatsoever, whether or not such Note shall be
overdue, and the Company shall not be affected by notice to the contrary.

                 12F.  Lost Notes.  Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
any Note and, in the case of such loss, theft or destruction, upon receipt of
your indemnity agreement in form and substance reasonably satisfactory to the
Company (or other indemnity reasonably satisfactory to the Company), or in the
case of any such mutilation, upon surrender and cancellation of such Note, the
Company will make and deliver a new Note in lieu of the lost, stolen, destroyed
or mutilated Note.

                 12G.  Survival of Representations and Warranties.  All
representations and warranties contained herein or made in writing by the
Company in connection herewith shall survive the execution and delivery of this
Agreement and of the Notes, regardless of any investigation made by you or on
your behalf.

                 12H.  Successors and Assigns.  All covenants and agreements in
this Agreement contained by or on behalf of either of the parties hereto shall
bind and inure to the benefit of the respective successors and assigns of the
parties hereto whether so expressed or not, except that the Company may not
assign or transfer any of its rights or obligations under this Agreement except
as provided in Section 6E.

                 12I.  Notices.  All communications provided for hereunder
shall be sent by first class mail, courier service or facsimile or hand
delivered and, if to you, addressed to you at the address set forth by you for
such communications on Annex 2 hereto, and if to the Company, at 10700
Frankstown Road, Pittsburgh, PA 15235, or to such other address with respect to

To Each of the Holders
  Named in Schedule I Hereto

Ladies and Gentlemen:

         Reference is made to the Note Agreement dated as of December 1, 1990
(the "Note Agreement") between Chambers Development Company, Inc., a Delaware
corporation (the "Company"), and each of the institutional investors named
therein pursuant to which $192,000,000 aggregate principal amount of the
Company's 10.45% Senior Notes due December 30, 2000 were issued.  The Note
Agreement subsequently was amended by a Waiver and First Amendment to Note
Agreement dated December 23, 1992 and an Extension of Waiver and Second
Amendment to Note Agreement dated March 1, 1993 and was then amended and
restated by an Amended and Restated Secured Note Agreement dated as of July 9,
1993 (the "Amended and Restated Agreement").  The Amended and Restated
Agreement is hereinafter referred to as the "Outstanding Agreement" and the
11.45% Senior Secured Notes due December 30, 1999 outstanding thereunder are
hereinafter referred to as the "Outstanding Notes."  You are the Holders of
Outstanding Notes in the aggregate principal amount set forth opposite your
name in the attached Schedule I.  You and the other Holders of Outstanding
Notes, together with any assignee or transferee, are sometimes referred to
herein individually as a "Holder" or "Purchaser" and collectively as the
"Holders" or "Purchasers."

         The Company agrees with you as follows:

Section 1.       AMENDMENTS OF AGREEMENT AND NOTES

         1.1.    Amendments.  The Holders and other creditors of the Company
have heretofore agreed to waive certain defaults and events of noncompliance by
the Company and the Holders and such other creditors also have heretofore
amended the agreements evidencing the Company's indebtedness, including the
Note Agreement and the notes originally issued thereunder.  The Company and the
Holders wish to amend and restate the Outstanding Agreement to be in the form
of this Agreement (the "Agreement") and to amend the Outstanding Notes to be in
substantially the form of the attached Exhibit A (the "Notes") and to amend the
guaranty previously delivered by the Company's Subsidiaries to be in the form
of the attached Exhibit B.  The Notes shall bear interest at the rate of 11.45%
per annum prior to maturity, payable quarterly on March 30, June 30, September
30 and December 30 of each year and at maturity, shall bear interest on overdue
principal (including any overdue required or optional prepayment), on any
Make-Whole Amount and (to the extent legally enforceable) on any overdue
installment of interest at the rate of 13.45% per annum, and shall be expressed
to mature on December 31, 1996.

         Subject to the terms and conditions hereof and on the basis of the
representations and warranties herein contained and fulfillment of the
conditions set forth herein, the parties agree that the Outstanding Note
Agreement shall be amended to be in the form of this Agreement, and the
Outstanding Notes shall be amended to be in the form of the Notes.

         This Agreement shall become effective following its execution and
delivery by all of the signatories listed on the signature pages and upon
satisfaction of all of the conditions set forth in Section 4, all of which
shall take place at 9:00 A.M. Chicago Time on the date set forth above (the
"Effective Date").  Delivery of the opinions and certificates called for by
Section 4 shall take place at the offices of Gardner, Carton & Douglas, 321
North Clark Street, Chicago, Illinois 60610.

         It shall not be necessary for Holders to surrender their Outstanding
Notes in exchange for the Notes.  However, prior to any transfer of your Notes
you agree to make a notation thereon that such Note has been amended.

<PAGE>   3
         1.2.    Security.  As part of the earlier restructuring, the
Outstanding Notes were, or were to be, secured to the extent and in the manner
provided in the Consolidated Collateral Documents and the parties intend that
such outstanding security continue unabated and unaffected for the Notes, that
the Notes are secured thereby and have the benefit thereof and that such
additional contemplated security, including the Mortgages, to the extent not
heretofore provided, shall promptly be hereafter provided.

         1.3.    Fees.  As consideration for the Holders' efforts and
cooperation in further restructuring the Company's indebtedness, the Company,
concurrently with the effectiveness of this Agreement, is paying the Holders in
cash an amount equal to .25% of the outstanding principal amount of the Notes.
In addition, the Company shall pay on the dates set forth below a cash fee
equal to the percentage set forth below of the then outstanding principal
amount of the Notes:

         1.4.    Common Stock.  As additional consideration for the agreements
of the Holders, the Company agrees to issue to the Holders on October 1, 1995
and on April 1, 1996 shares of the Company's Class A Common Stock, $.50 par
value (the "Common Shares"), which after issuance thereof, represent on each
such date the Pro Rata Share of 4% of the Company's then outstanding shares of
Common Stock of all classes.  Of such number of Common Shares, each Holder
shall be entitled to its pro rata portion based on the amount of its then
unpaid principal.  Concurrently with the execution and delivery of this
Agreement, the Company and holders of its Senior Debt, including the Holders,
are entering into the Registration Rights Agreement (the "Registration
Agreement"), pursuant to which the Company agrees to register the Common
Shares.

         2.1.    Required Prepayments.  In addition to payment of all

Notes which may be outstanding from time to time, the Company shall prepay and
there shall become due and payable on the dates set forth below, the portion of
the principal amount of the Notes set forth below or such lesser amount as
would constitute payment in full on the Notes, at a price of 100% of the

Notwithstanding the foregoing the Company, by notice to Holders not less than 2
Business Days prior to the prepayment date, may at its option elect to defer a
portion, but in any event not more than 75% of the prepayment due on December
30, 1995 and all or any portion of the prepayment due on December 30, 1996
until December 31, 1996.

        2.2.    Optional Prepayments; Mandatory Offers to Prepay.  (a)  Upon
notice as provided in Section 2.3(a) and (d), the Company may prepay the Notes,
in whole or in part, at any time, in an amount not less than $1,000,000 or an
integral multiple of $10,000 in excess thereof.  Each such prepayment shall be
at a price of 100% of the principal amount to be prepaid, plus interest accrued
thereon to the date of prepayment, plus the Make-Whole Amount, if any.

         (b)     In the event that (i) there shall be any Disposition pursuant
to clause (i) of Section 7.9 or (ii)

                                       2
<PAGE>   4

there shall be Excess Unrestricted Cash Balances as of the end of any
month, or (iii) the Company shall be obligated to make a prepayment pursuant to
Section 3.02(iii) or 3.02(vii) of the Intercreditor Agreement, or (iv) there
shall be a Disposition pursuant to clause (iii) of Section 7.9 of this
Agreement, the Company, pursuant to the notice provided in Section 2.3(b), shall
offer to prepay Notes in aggregate principal amount equal to (w) the Pro Rata
Share of 50% of the Net Proceeds from such Disposition referred to in foregoing
clause (i), (x) the Pro Rata Share of 100% of such Excess Unrestricted Cash
Balances, (y) the amount of such required prepayment under the Intercreditor
Agreement, or (z) the Pro Rata Share of 100% of the Net Proceeds from such
Disposition referred to in foregoing clause (iv), as the case may be.  Each such
prepayment shall be at a price of 100% of the principal amount to be prepaid,
plus interest accrued thereon to the date of payment.

         (c)     In the event of an anticipated or actual Change of Control,
the Company, pursuant to the notice provided in Section 2.3(c), shall offer to
prepay the entire principal amount of the Notes held by each Holder at a price
equal to 100% of the principal amount thereof plus accrued interest to the date
of prepayment.

         (d)     Upon notice as provided in Section 2.3(a), the Company may
offer to prepay the Notes, in whole or in part, at any time at a price of 100%
of the principal amount to be prepaid, plus interest accrued thereon to the
date of prepayment.  Any offer to prepay pursuant to this paragraph (d) shall
be made only as a part of an offer to prepay, pro rata, all or a portion of the
Bank Debt and the 11.95% Senior Notes on the same terms and at the same price
as the offer to prepay the Notes.

         (e)     Any prepayment pursuant to Section 2.2 of less than all of the
Notes outstanding shall be applied to reduce, pro rata, the prepayments and
payment at maturity required by Section 2.1.

         (f)     Except as provided in Section 2.1, Section 6.12 and this
Section 2.2, the Notes shall not be prepayable in whole or in part.

         2.3.    Notice of Prepayments.  (a)  The Company shall give notice of
any optional prepayment of the Notes pursuant to Section 2.2(a) or (d) to each
Holder of the Notes not less than 30 days nor more than 60 days before the date
fixed for prepayment, specifying (i) such date, (ii) the principal amount of
the Holder's Notes to be prepaid, (iii) the date as of which the Make-Whole
Amount, if any, will be calculated, (iv) a calculation of the estimated
Make-Whole Amount, if any, showing in detail the method of calculation, (v) the
accrued interest applicable to the prepayment and (vi) that, in the case of an
offer to prepay pursuant to Section 2.2(d), any Holder electing not to accept
such offer must do so by notice to the Company not less than 1 day prior to the
date fixed for prepayment.  Notice of prepayment having been so given, the
aggregate principal amount of the Notes specified in such notice, together with
accrued interest thereon and the Make-Whole Amount, if any, shall become due
and payable on the prepayment date.  If one or more Holders elects not to
accept an offer made pursuant to Section 2.2(d), its or their portion of such
prepayment shall be applied by the Company on a pro rata basis to the
prepayment of Notes held by Holders accepting the offer, and if no Holder
accepts the offer or if a balance would remain after application to all
accepting Holders, then such prepayment or balance shall be applied in
accordance with the Intercreditor Agreement.

        (b)     The Company shall give notice of any mandatory offer to prepay
the Notes pursuant to Section 2.2(b) not later than 2 days after receipt of Net
Proceeds by the Company or any Subsidiary, on the Business Day following the
delivery of the certificate pursuant to Section 6.6(e) or not later than 2 days
after the Company learns it will be necessary to make a prepayment pursuant to
Section 3.02(iii) or 3.02(vii) of the Intercreditor Agreement (and in any event
not later than 1 day after such obligation arises), as the case may be.  Such
notice shall be certified by an authorized officer and shall specify (i) that it
is given pursuant to this Section 2.3(b), (ii) the source of the funds to be
used, (iii) the date fixed for prepayment which shall be not less than 5 nor
more than 7 days after the date of delivery of such certification, (iv) that any
Holder electing not to accept such offer must do so by notice to the Company not
less than 1 day prior to the date fixed for prepayment, (v) the principal amount
of the Holder's Notes to be prepaid and (vi) the accrued interest applicable to
the prepayment.  If one or more Holders elects not to accept such offer, its or
their portion of such prepayment shall be applied by the Company on a pro rata
basis to the prepayment of Notes held by Holders accepting the offer, and if no
Holder accepts the offer or if a balance would remain after application to all
accepting Holders, then such prepayment or balance shall be applied in
accordance with the Intercreditor Agreement.

         (c)     The Company shall give notice of any offer to prepay the Notes
pursuant to Section 2.2(c) to each Holder of the Notes (i) not more than 90 and
not less than 60 days prior to the date on which such Change of Control is
projected to occur or (ii) if such Change of Control occurs without the
knowledge of the Company, not later than 3 days after the Company learns of
such Change of Control.  Such notice shall be 





                                       3
<PAGE>   5



certified by an authorized officer of the Company and shall specify (i)
the nature of the Change of Control, (ii) the date on which it is projected to
occur or on which it occurred, as the case may be, (iii) the date fixed for
prepayment which shall be not less than 30 or more than 45 calendar days after
the giving of such notice and in any event (except for the situation described
in clause (ii) of the preceding sentence) prior to the projected date of the
Change of Control, (iv) the accrued interest applicable to the prepayment and
(v) the date by which any Holder of a Note that wishes to accept such offer must
deliver notice thereof to the Company which shall not be later than 10 calendar
days prior to the date fixed for prepayment.  Not earlier than 7 calendar days
prior to the date fixed for prepayment, the Company shall give written notice to
each Holder of those Holders, and the principal amount of Notes held by each,
who have given notices of acceptance of the Company's offer, and thereafter any
Holder may change its response to the Company's offer by written notice to such
effect delivered to the Company not less than 3 calendar days prior to the date
fixed for prepayment.  Upon receipt by the Company of any non-revoked notice of
acceptance from any Holder within the required time period, the aggregate
principal amount of Notes held by such Holder, together with accrued interest
thereon, shall become due and payable on the prepayment date.  If, prior to the
time prepayment is made, such Change of Control (actual or anticipated) is
canceled, the Company may rescind such offer to prepay by delivery of a
certificate of an authorized officer to such effect to each Holder of Notes.

         (d)     In connection with a prepayment pursuant to Section 2.2(a),
the Company also shall give notice to each Holder of the Notes by telecopy,
telegram, telex or other same-day written communication, as soon as practicable
but in any event not later than two business days prior to the prepayment date,
of the Make-Whole Amount, if any, applicable to such prepayment and the details
of the calculations used to determine the Make-Whole Amount.

         2.4.    Surrender of Notes on Prepayment or Exchange.  Subject to
Section 2.5, upon any partial prepayment of a Note pursuant to this Section 2
or partial exchange of a Note pursuant to Section 10.3, such Note may, at the
option of the Holder thereof, (i) be surrendered to the Company pursuant to
Section 10.3 in exchange for a new Note equal to the principal amount remaining
unpaid on the surrendered Note, or (ii) be made available to the Company, at
the Company's principal office, for notation thereon of the portion of the
principal so prepaid or exchanged.  In case the entire principal amount of any
Note is prepaid, such Note shall be surrendered to the Company for cancellation
and shall not be reissued, and no Note shall be issued in lieu of such Note.

         2.5.    Direct Payment.  Notwithstanding any other provision contained
in the Notes or this Agreement, the Company will pay all sums becoming due on
each Note held by you or any subsequent Institutional Holder by wire transfer
of immediately available funds to such account as you or such subsequent
Institutional Holder have designated in Schedule I, or as you or such
subsequent Institutional Holder may otherwise designate by notice to the
Company, in each case without presentment and without notations being made
thereon, except that any such Note so paid or prepaid in full shall be
surrendered promptly thereafter to the Company for cancellation.  Any wire
transfer shall identify such payment in the manner set forth in Schedule I and
shall identify the payment as principal, Make-Whole Amount, if any, and/or
interest.  You and any subsequent Institutional Holder of a Note to which this
Section 2.5 applies agree that, before selling or otherwise transferring any
such Note, you or it will make a notation thereon of the aggregate amount of
all payments of principal theretofore made and of the date to which interest
has been paid and, upon written request of the Company, will provide a copy of
such notations to the Company.

         2.6.    Allocation of Payments.  Except in the case of prepayments
pursuant to Sections 2.2(b) (unless all Holders accept), 2.2(c), 6.12(d),
6.12(e), 6.12(f) and 6.12(g), if less than the entire principal amount of all
the Notes outstanding is to be paid, the Company will prorate the aggregate
principal amount to be paid among the outstanding Notes in proportion to the
unpaid principal.

         2.7.    Payments Due on Saturdays, Sundays and Holidays.  If the date
of any required prepayment of the Notes or any interest payment date on the
Notes or the date fixed for any other payment of any Note or exchange of any
Note is a day other than a Business Day, then such payment, prepayment or
exchange shall not be made on such date but shall be made on the next
succeeding Business Day, with interest payable to the actual date of payment.

         2.8.    Minimum Prepayments.  During the period commencing August 31,
1994 and ending on and including December 31, 1995 the Company shall prepay,
pursuant to Section 2.1 or 2.2, not less than $30,264,000 principal amount of
the Notes, at least $10,088,000 of which shall be prepaid on or prior to
January 31, 1995.  The prepayments made between August 31, 1994 and the date of
this Agreement, 




                                       4

aggregating $6,652,686.57, shall be credited against the requirements of
this Section 2.8.  

Section 3.       REPRESENTATIONS

         3.1.    Representations of the Company.  As an inducement to, and as
part of the consideration for, your entering into this Agreement, the Company
represents and warrants to you as follows:

         (a)     Corporate Organization and Authority.  The Company is a
solvent corporation duly organized, validly existing and in good standing under
the laws of the State of Delaware, has all requisite corporate power and
authority to own and operate its properties, to carry on its business as now
conducted and as presently proposed to be conducted, to enter into and perform
the Agreement, and the Registration Agreement and to issue and sell the Notes
and the Common Shares as contemplated in the Agreement.

         (b)     Qualification to Do Business.  The Company is duly licensed or
qualified and in good standing as a foreign corporation authorized to do
business in each jurisdiction where the nature of the business transacted by it
or the character of its properties owned or leased makes such qualification or
licensing necessary, except for jurisdictions, individually or in the
aggregate, where the failure to be so licensed or qualified would not have a
material adverse effect on the business, properties, operations or condition,
financial or otherwise, of the Company and its Subsidiaries, taken as a whole.

         (c)     Subsidiaries.  The Company has no Subsidiaries, as defined in
Section 5.1, except those listed in the attached Annex I, which correctly sets
forth the jurisdiction of incorporation and the percentage of the outstanding
Voting Stock or equivalent interest of each Subsidiary which is owned, of
record or beneficially, by the Company and/or one or more Subsidiaries.  Each
Subsidiary has been duly organized and is validly existing and in good standing
under the laws of its jurisdiction of incorporation or organization and is duly
licensed or qualified and in good standing as a foreign corporation in each
other jurisdiction where the nature of the business transacted by it or the
character of its properties owned or leased makes such qualification or
licensing necessary, except for jurisdictions, individually or in the
aggregate, where the failure to be so licensed or qualified would not have a
material adverse effect on the business, properties, operations or condition,
financial or otherwise, of the Company and its Subsidiaries, taken as a whole.
Each Subsidiary has full corporate power and authority to own and operate its
properties and to carry on its business as now conducted and as presently
proposed to be conducted.  The Company and each Subsidiary have good and
marketable title to all of the shares they purport to own of the capital stock
of each Subsidiary, free and clear in each case of any Lien, except as
otherwise disclosed in the attached Annex II, and all such shares have been
duly issued and are fully paid and nonassessable.

         (d)     Financial Statements.  The consolidated balance sheets of the
Company and its Subsidiaries as of December 31, 1990, 1991, 1992 and 1993, and
the related consolidated statements of operations, stockholders' equity and
cash flows for the years ended on such dates, accompanied by the reports and
opinions of Deloitte & Touche, independent certified public accountants, copies
of which have heretofore been delivered to you, were prepared in accordance
with generally accepted accounting principles consistently applied throughout
the periods involved (except as otherwise noted therein) and present fairly the
consolidated financial position and consolidated results of operations
and cash flows of the Company and its Subsidiaries for and as of the end of
each of such years.  The unaudited condensed consolidated balance sheets of the
Company as of March 31 and June 30, 1993 and 1994, the unaudited condensed
consolidated statements of operations for the three months ended March 31 and
three and six months ended June 30, 1993 and 1994, and the unaudited condensed
consolidated statements of cash flows for the three months ended March 31 and
six months ended June 30, 1993 and 1994 were prepared in accordance with
generally accepted accounting principles for interim financial statements
consistently applied during the periods involved and present fairly the
consolidated financial position and consolidated results of operations and cash
flows of the Company and its Subsidiaries for and as of the end of each such
period.

         (e)     No Contingent Liabilities or Adverse Changes.  Neither the
Company nor any of its Subsidiaries has any contingent liabilities which are
material to the Company and its Subsidiaries taken as a whole, other than as
indicated in the 1993 audited financial statements heretofore delivered to you,
and, since December 31, 1993, except for changes disclosed or reflected in the
unaudited 1994 financial statements heretofore delivered to you, there have
been no changes in the condition, financial or otherwise, of the Company and
its Subsidiaries except changes occurring in the ordinary course of business,
none of which, individually or in the aggregate, has been materially adverse.

         (f)     No Pending Litigation or Proceedings.  Except as described in
the notes to the 1993 audited financial statements referred to in the foregoing
paragraph (e) of this Section 3.1, there are no actions, suits or 




                                       5
<PAGE>   7



proceedings pending or threatened against or affecting the Company or
any of its Subsidiaries, at law or in equity or before or by any Federal, state,
municipal or other governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, which might reasonably be expected to
result, either individually or in the aggregate, in any material adverse change
in the business, properties, operations or condition, financial or otherwise, of
the Company and its Subsidiaries taken as a whole.

         (g)     Compliance with Law.  (i)  Neither the Company nor any of its
Subsidiaries is:  (x) in default with respect to any order, writ, injunction or
decree of any court to which it is a named party; or (y) in default under any
law, rule, regulation, ordinance or order relating to its or their respective
businesses, the sanctions and penalties resulting from which defaults described
in clauses (x) and (y) might reasonably be expected to have a material adverse
effect on the business, properties, operations, assets or condition, financial
or otherwise, of the Company and its Subsidiaries taken as a whole, or on the
Company's ability to perform its obligations under this Agreement or the Notes.

                 (ii)     Neither the Company nor any Subsidiary nor any
Affiliate of the Company is an entity defined as a "designated national" within
the meaning of the Foreign Assets Control Regulations, 31 C.F.R. Chapter V, or
for any other reason, subject to any restriction or prohibition under, or is in
violation of, any Federal statute or Presidential Executive Order, or any rules
or regulations of any department, agency or administrative body promulgated
under any such statute or Order, concerning trade or other relations with any
foreign country or any citizen or national thereof or the ownership or
operation of any property.

         (h)     Pension Reform Act of 1974.  Neither the execution and delivery
of this Agreement nor the consummation of any of the transactions contemplated
by this Agreement is or will constitute a "prohibited transaction" within the
meaning of Section 4975 of the Internal Revenue Code of 1986, as amended (the
"Code"), or Section 406 of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA").  Although the Internal Revenue Service has not issued
(nor has the Company or any Subsidiary requested) a determination that each
"employee pension benefit plan," as defined in Section 3 of ERISA (a "Plan"),
established, maintained or contributed to by the Company or any Subsidiary
(except for any Plan which is unfunded and maintained primarily for the purpose
of providing deferred compensation for a select group of management or highly
compensated employees) is qualified under Section 401(a) and related provisions
of the Code or that each related trust or custodial account is exempt from
taxation under Section 501(a) of the Code, the Company believes that such Plans
so qualify, that such trusts or accounts are so exempt and that, when request
is so made, the Internal Revenue Service will so determine. All Plans of the
Company or any Subsidiary comply in all material respects with ERISA and other
applicable laws.  There exist with respect to the Company or any Subsidiary no
"multi-employer plans," as defined in the Multi-employer Pension Plan
Amendments Act of 1980, for which a material withdrawal or termination
liability may be incurred.  There exist with respect to all Plans or trusts
established or maintained by the Company or any Subsidiary:  (i) no accumulated
funding deficiency within the meaning of ERISA; (ii) no termination of any Plan
or trust which could result in any liability to the Pension Benefit Guaranty
Corporation ("PBGC") or any "reportable event," as that term is defined in
ERISA, which could constitute grounds for termination of any Plan or trust by
the PBGC; and (iii) no "prohibited transaction," as that term is defined in
ERISA, which could subject any Plan, trust or party dealing with any such Plan
or trust to any tax or penalty on prohibited transactions imposed by Section
4975 of the Code.

         (i)     Title to Properties.  Except as disclosed in the 1993 audited
financial statements heretofore delivered to you, the Company and each
Subsidiary has (i) good and marketable title in fee simple or its equivalent
under applicable law to all the real property owned by it and (ii) good and
marketable title to all of the other property reflected in such financial
statements or subsequently acquired by the Company or any Subsidiary (except as
sold or otherwise disposed of in the ordinary course of business or
contemplated by this Agreement or consented to by the Holders), in each case
free from all Liens or defects in title except (x) Liens created or permitted
by the Consolidated Collateral Documents, (y) Liens securing Indebtedness of
the Company or a Subsidiary, which are listed in the attached Annex II and (z)
other Liens and minor defects in title, which primarily relate to nonoperating
properties, that, in the aggregate, do not materially detract from the value of
such properties or materially impair their use in the operation of the business
of the Company and its Subsidiaries.

         (j)     Leases.  The Company and each Subsidiary enjoy peaceful and
undisturbed possession under all leases under which the Company or such
Subsidiary is a lessee or is operating.  None of such leases contains any
provision which might reasonably be expected to materially and adversely affect
the operation or use of the 



                                       6
<PAGE>   8
properties so leased.  All of such leases are valid and subsisting and
none of them is in default.

         (k)     Franchises, Patents, Trademarks and Other Rights.  The Company
and each Subsidiary have all franchises, permits (or similar rights pending
receipt of permits which have been applied for and which the Company has no
reason to believe will not be granted), licenses and other authority necessary
to carry on their businesses as now being conducted, and none are in default
under any of such franchises, permits, licenses or other authority which are
material to their businesses, properties, operations or condition, financial or
otherwise taken as a whole.  The Company and its Subsidiaries own or possess
all patents, trademarks, service marks, trade names, copyrights, licenses and
rights with respect to the foregoing necessary for the present conduct of their
businesses, without any known conflict with the rights of others which might
result in any material adverse change in their businesses, properties,
operations or condition, financial or otherwise, taken as a whole.

        (l)     Authorization.  This Agreement, the Consolidated Collateral

equitable principles, regardless of whether enforcement is sought in equity or

Documents do, and the Guaranty when executed and delivered will, constitute the
legal, valid and binding obligations of such Subsidiary, enforceable in
accordance with their terms, except to the extent that enforcement thereof may

Subsidiaries, as the case may be, with all of the provisions of this Agreement,
the Guaranty, the Consolidated Collateral Documents, the Registration Agreement,
the Notes and the Common Shares (i) are within their respective corporate
powers, (ii) have been, or will be as to the Common Shares, duly authorized by

of any Lien not provided for or permitted therein on any property of the Company
or any Subsidiary under the provisions of, any charter document, by-law, loan
agreement or other agreement or instrument to which the Company or any
Subsidiary is a party or by which any of them or their property may be bound.

which have been waived to the extent provided in Section 11.10, there exist no
Defaults or Events of Default.  Neither the Company nor any Subsidiary is in

any of its Subsidiaries, their respective businesses or properties, nor any
relationship between the Company or any of its Subsidiaries and any other
Person, nor any circumstances in connection with the offer, issue, sale or
delivery of the Notes or the Common Shares is such as to require a consent,
approval or authorization of, or withholding of objection on the part of, or
filing, registration or qualification with, any governmental authority on the

due since such date is pending or to the Company's knowledge threatened.  The
provisions for taxes on the books of the Company and each Subsidiary are

Section 6.    AFFIRMATIVE COVENANTS

         The Company agrees that, for so long as any amount remains unpaid on
any Note or pursuant to the Consolidated Collateral Documents:

         6.1.    Corporate Existence.  The Company will maintain and preserve,
and will cause each Subsidiary to maintain and preserve, its corporate
existence and right to carry on its business and use, and cause each Subsidiary
to use, its best efforts to maintain, preserve, renew and extend all of its
rights, powers, privileges and franchises necessary to the proper conduct of
its business; provided, however, that the foregoing shall not prevent any
transaction permitted by Section 7.8 and provided further, that nothing in this
Section 6.1 shall prevent the termination of the corporate existence of any
Subsidiary if, in the opinion of the Board of Directors of the Company, such
termination is in the best interests of the Company, is not disadvantageous to
Holders of the Notes and is not otherwise prohibited by this Agreement.

         6.2.    Insurance.  The Company will insure and keep insured at all
times all of its properties and all of its Subsidiaries' properties which are
of an insurable nature and of the character usually insured by companies
operating similar properties against loss or damage by fire and from other
causes customarily insured 

                                      16

<PAGE>   18

against by companies engaged in similar businesses in such amounts as are
usually insured against by such companies.  The Company also will maintain for
itself and its Subsidiaries at all times adequate insurance against loss or
damage from such hazards and risks to the person and property of others as are
usually insured against by companies operating properties similar to the
properties of the Company and its Subsidiaries.  All such insurance (other than
permitted self-insurance) shall be carried with financially sound and reputable
insurers accorded a rating of A- and VII or better by A.M. Best Company, Inc.,
unless any such insurance is not available on commercially reasonable terms from
an insurer so rated, in which case it shall be carried by a financially sound
and reputable insurer which in the opinion of the Company most closely
approximates the criteria necessary to obtain such rating.  The Company may
self-insure (i) without limitation to the extent such self-insurance is fully
collateralized by cash or letters of credit and (ii) otherwise in amounts which,
in the aggregate, do not at any time exceed 13% of Consolidated Tangible Net
Worth.  At no time will the Company's and its Subsidiaries' insurance be less
than that carried on the date hereof unless such insurance becomes unavailable. 
A summary of insurance presently in force, including self-insurance and
deductibles, is contained in the attached Annex V.

         6.3.    Taxes, Claims for Labor and Materials.  The Company will pay
and discharge when due, and will cause each Subsidiary to pay and discharge
when due, all taxes, assessments and governmental charges or levies imposed
upon it or its property or assets, or upon properties leased by it (but only to
the extent required to do so by the applicable lease), other than taxes which
individually and in the aggregate are not material in amount and the
non-payment of which would not have a material adverse effect on the business,
properties, operations or condition, financial or otherwise, of the Company and
its Subsidiaries taken as a whole, prior to the date on which penalties attach
thereto, and all lawful claims which, if unpaid, might become a Lien upon its
property or assets, provided that neither the Company nor any Subsidiary shall
be required to pay any such tax, assessment, charge, levy or claim, the payment
of which is being contested in good faith and by proper proceedings that will
stay the forfeiture or sale of any property and with respect to which adequate
reserves are maintained in accordance with generally accepted accounting
principles.

         6.4.    Maintenance of Properties.  The Company will maintain,
preserve and keep, and will cause each Subsidiary to maintain, preserve and
keep, its properties (whether owned in fee or a leasehold interest) in good
repair and working order, ordinary wear and tear excepted, and from time to
time will make all necessary repairs, replacements, renewals and additions.

         6.5.    Maintenance of Records.  The Company will keep, and will cause
each Subsidiary to keep, at all times proper books of record and account in
which full, true and correct entries will be made of all dealings or
transactions of or in relation to the business and affairs of the Company or
such Subsidiary, in accordance with generally accepted accounting principles
consistently applied throughout the period involved (except for such changes as
to consistency only as are disclosed in such financial statements or in the
notes thereto), and the Company will, and will cause each Subsidiary to,
provide reasonable protection against loss or damage to such books of record
and account.

        6.6.    Financial Information and Reports.  The Company will furnish to
you and to any other Institutional Holder (in duplicate if you or such other
Holder so request and provided that only another Institutional Holder which is
not a Competitor shall be entitled to receive the information specified in
clause (ii) of paragraph (e) and paragraphs (j) and (m) of this Section 6.6),

Internal Revenue Service, the Department of Labor or the PBGC with respect to
any of the foregoing which, in any of the events specified above, would result
in any material liability of the Company or any of its Subsidiaries.

         6.9.    Compliance with Laws.  (a)  The Company will comply, and will
cause each Subsidiary to comply, with all laws, rules and regulations,
including Environmental Laws, relating to its or their respective businesses,
other than laws, rules and regulations the failure to comply with which or the
sanctions and penalties resulting therefrom, individually or in the aggregate,
would not have a material adverse effect on the business, properties,
operations, or condition, financial or otherwise, of the Company and its
Subsidiaries taken as a whole, and which would not result in the creation of a
Lien which, if incurred in the ordinary course of business, would not be
permitted by Section 7.6 on any of the property of the Company or any
Subsidiary; provided, however, that the Company and its Subsidiaries shall not
be required to comply with laws, rules and regulations the validity or
applicability of which are being contested by it or them in good faith and by
appropriate proceedings and as to which the Company has established adequate
reserves on its books.

         (b)     Promptly upon the occurrence thereof, the Company will give
you and each other Institutional Holder written notice of the institution of
any proceedings against, or the receipt of notice of potential liability or
responsibility of, the Company or any Subsidiary for violation, or the alleged
violation, of any Environmental Law which violation, individually or together
with all other alleged violations, could give rise to a material liability of
the Company and its Subsidiaries taken as a whole.

         6.10.   Acquisition of Notes.  Neither the Company nor any Subsidiary
or Affiliate, directly or indirectly, will repurchase or offer to repurchase
any Notes unless the offer is made to repurchase Notes pro rata from all
Holders at the same time and on the same terms.  The Company will forthwith
cancel any Notes in any manner or at any time acquired by the Company or any
Subsidiary or Affiliate and such Notes shall not be deemed to be outstanding
for any of the purposes of this Agreement or the Notes.

         6.11.    Reserved

         6.12.   Nature of Business.  (a)  Subject to paragraphs (b) through
(g) hereof, the Company will, and will cause each Subsidiary to, engage only in
the business of (i) Non-Hazardous Waste management (including recycling and
composting), (ii) incineration and disposal of Non-Hazardous Wastes, (iii)
transportation of Non-Hazardous Wastes, and (iv) operations ancillary to the
foregoing.

         (b)     Without reference to paragraphs (c) through (g) of this
Section 6.12, in the event of the acquisition by the Company or a Subsidiary of
a business an incidental portion of which (less than 25% of the assets and
revenues of such business and less than 5% of the consolidated revenues of the
Company and its Subsidiaries on a pro-forma basis) is not described in clauses
(i) through (iv) of paragraph (a) of this Section 6.12, the Company shall have
180 days from the date of such acquisition to discontinue or dispose of such
noncomplying activities before it shall be deemed to be in violation of this
Section 6.12.  The Company shall give prompt written notice, but in any event
within 10 days of each event specified in clauses (i) and (ii) of paragraph (a)
of this Section 6.12, to each Holder of Notes of (i) any such acquisition,
specifying in reasonable detail the noncomplying activities and (ii) the
discontinuance or disposition of such noncomplying activities.  This paragraph
(b) shall not be available for the acquisition of any business a greater than
incidental portion of which violates this Section 6.12.

         (c)     The reclassification to hazardous (a "Reclassification"), by
law or by any regulatory authority, of Non-Hazardous Waste ("Reclassified
Waste") being managed (which term shall be deemed to include incineration,
disposal, storage and transportation) by the Company or any of its Subsidiaries
or contracted to be managed by the Company or any of its Subsidiaries or with
respect to which the Company or any of its Subsidiaries has been issued a
permit to manage by a regulatory authority during the term of this Agreement
shall not be deemed a violation of this Section 6.12 if, immediately following
such Reclassification, (x) the Company's handling of such Reclassified Waste
complies in all material respects with all applicable permits, laws and
regulations and (y) the consolidated revenues produced from the management of
Reclassified Waste do not exceed 5% of the Company's consolidated revenues for
the twelve months ended as of the Company's most recently completed fiscal
quarter prior to the effective date of the Reclassification.  The Company shall
give written notice of a Reclassification within 10 days of such
Reclassification.

         (d)     If, as a result of a Reclassification, the consolidated
revenues produced from the management of Reclassified Waste exceed 5% of the
Company's consolidated revenues for the twelve months ended as of the end of
the most recently completed fiscal quarter prior to the effective date of the
Reclassification, the Company shall, within 30 days after the effective date of
such Reclassification, give written notice to each Holder of a Note of such
fact, specifying in reasonable detail the nature of such Reclassification and
the amount and percentage of consolidated revenues produced by the management
of Reclassified Waste.  Such notice shall contain the written offer of the
Company to prepay, on a date specified in such notice which shall be a business
day not less than 160 nor more than 180 calendar days after the effective date

sufficient portion of the Reclassified Waste management activities so that,
after giving effect thereto, the consolidated revenues produced from management

revenues for the period specified in the first sentence of this paragraph (d),
the Company may revoke its prepayment offer by written notice to each Holder of
Notes not less than 5 days prior to the payment date specified in the offer,
which notice shall specify the actions taken and set forth the calculations of
consolidated revenues, and the Company's obligation to prepay the Notes shall

recently completed fiscal quarter prior to the effective date of the 
Reclassification, the Company shall, within 30 days after the effective
date of such Reclassification, give written notice to each Holder of a Note of
such fact, specifying in reasonable detail the nature of such Reclassification
and the amount and percentage of consolidated revenues produced by the Company
and its Subsidiaries from the management of Reclassified Waste.  Such notice
shall contain the written offer of the Company to prepay, on a date specified
in such notice which shall be a business day not less than 160 nor more than
180 calendar days after the effective date of such Reclassification, the entire
principal amount of the Notes held by each Holder at a price equal to 100% of
the principal amount thereof plus accrued interest to the date of prepayment
plus the Make-Whole Amount, and shall state that notice of acceptance of the
Company's offer to prepay under this Section 6.12(e) must be delivered to the
Company within 115 calendar days after receipt of the Company's notice.  Any
Holder may revoke its acceptance of the Company's offer by written notice to
such effect delivered to the Company not less than 15 days prior the date fixed
for prepayment.  In the event the Company discontinues or disposes of a
sufficient portion of the Reclassified Waste management activities so that
after giving effect thereto, the revenues produced from management of the
Reclassified Waste would be less than 5% of the Company's consolidated revenues
for the period specified in the first sentence of this paragraph (e), the
Company may revoke its prepayment offer by written notice to each Holder of
Notes not less than 5 days prior to the payment date specified in the offer,
which notice shall specify the actions taken and set forth the calculations of
consolidated revenues, and the Company's obligation to prepay the Notes shall
terminate.

         (f)     If as of the end of any fiscal quarter ending after a
Reclassification, the consolidated revenues produced from the management of
Reclassified Waste exceed 5% of the Company's consolidated revenues for the
twelve months then ended, the Company shall, not later than 30 days after the
end of such quarter, give written notice to each Holder of a Note of such fact,
specifying in reasonable detail the amount and percentage of consolidated
revenues produced from the management of Reclassified Waste.  Such notice shall
contain the written, irrevocable offer of the Company to prepay, on a date
specified in such notice which shall be a business day not less than 160 nor
more than 180 calendar days after the end of such quarter, the entire principal
amount of the Notes held by each Holder at a price equal to 100% of the
principal amount thereof plus accrued interest to the date of prepayment and
shall state that notice of acceptance of the Company's offer to prepay under
this Section 6.12(f) must be delivered to the Company within 115 calendar days
after receipt of the Company's notice.  Any holder may revoke its acceptance of
the Company's offer by written notice to such effect delivered to the Company
not less than 15 days prior to the date fixed for prepayment.  In the event the
Company disposes or discontinues all Reclassified Waste management activities
within 150 days after the end of the fiscal quarter referred to in the first
sentence of this paragraph, the Company may revoke its prepayment offer by

                                      21

written notice to each Holder of Notes not less than 50 days prior to the
payment date specified in the offer, which notice shall specify the actions
taken, and the Company's obligation to prepay the Notes shall terminate.

         (g)     If as of the end of any fiscal quarter ending after a
Reclassification, the consolidated revenues produced from the management of
Reclassified Waste exceed 25% of the Company's consolidated revenues for the
twelve months then ended, the Company shall not later than 30 days after the
end of such quarter, give written notice to each Holder of a Note of such fact,
specifying in reasonable detail the amount and percentage of consolidated
revenues produced from the management of Reclassified Waste.  Such notice shall
contain the written, irrevocable offer of the Company to prepay, on a date

the Make-Whole Amount, and shall state that notice of acceptance of the
Company's offer to prepay under this Section 6.12(g) must be delivered to the
Company within 115 calendar days after receipt of the Company's notice.  Any
Holder may revoke its acceptance of the Company's offer by written notice to
such effect delivered to the Company not less than 15 days prior to the date
fixed for prepayment.  In the event the Company disposes or discontinues all
Reclassified Waste management activities within 150 days after the end of the
fiscal quarter referred to in the first sentence of this paragraph, the Company
may revoke its prepayment offer by written notice to each holder of Notes not
less than 50 days prior to the payment date specified in the offer, which 
notice shall specify the actions taken, and the Company's obligation to 
prepay the Notes shall terminate.  

          6.13. Private Letter Rating.  The Company shall cooperate with the 
Holders and use its best efforts to obtain at its expense a private letter 
rating on the Notes from either Moody's Investor Services, Inc. or Standard & 
Poor's Corporation.  

          6.14.   Valuation of Businesses.  Upon the request of holders of 
more than 50% in principal amount of the outstanding Notes and 11.95%
Senior Notes, treated as a single group, the Company, at its expense, shall
arrange promptly for the valuation of its landfills and other businesses by one
or more qualified independent appraisers reasonably acceptable to the holders

11.95% Senior Notes, treated as a single group, and promptly shall provide
copies of such valuations to each holder.  The Company shall not be obligated
to arrange for such valuation more than twice during the term of this Agreement
and in no event in consecutive years.

          8.2.    Remedies on Default.  When any Event of Default described

principal amount of, 


                                      25
<PAGE>   27

together with the Make-Whole Amount (to the extent permitted by law),
and all interest accrued on all Notes to be, and such Notes shall thereupon
become, forthwith due and payable, without any presentment, demand, protest or
other notice of any kind, all of which are expressly waived.  Notwithstanding
the foregoing, (i) when any Event of Default described in paragraphs (a), (b)
or (c) of Section 8.1 has happened and is continuing, any Holder may by notice
to the Company declare the entire principal amount of, together with the
Make-Whole Amount (to the extent permitted by law), and all interest accrued on
the Notes then held by such Holder to be, and such Notes shall thereupon
become, forthwith due and payable, without any presentment, demand, protest or
other notice of any kind, all of which are expressly waived and (ii) when any
Event of Default described in clauses (i) through (vii) of paragraph (l) of
Section 8.1 has happened, then the entire principal amount of, together with
the Make-Whole Amount (to the extent permitted by law) and all interest accrued
on all outstanding Notes shall immediately become due and payable without
presentment, demand or notice of any kind.  Upon the Notes or any of them
becoming due and payable as aforesaid, the Company will forthwith pay to the
Holders of such Notes the entire principal of and interest accrued on such
Notes, plus the Make-Whole Amount (to the extent permitted by law) which shall
be calculated on the Determination Date.  

          8.3.    Annulment of Acceleration of Notes. The provisions of 
Section 8.2 are subject to the condition that if the principal of, Make-Whole 
Amount and accrued interest on the Notes have been declared immediately due 
and payable by reason of the occurrence of any Event of Default described in 
paragraphs (a) through (k), inclusive, of Section 8.1, the Holder or Holders 
of 66-2/3% in aggregate principal amount of the Notes then outstanding may, by 
written instrument filed with the Company, rescind and annul such declaration 
and the consequences thereof, provided that (i) at the time such declaration 
is annulled and rescinded no judgment or decree has been entered for the 
payment of any monies due pursuant to the Notes, this Agreement, the Guaranty 
or the Consolidated Collateral Documents, (ii) all arrears of interest upon 
all the Notes and all other sums payable under the Notes, under this Agreement 
(except any principal, interest or Make-Whole Amount on the Notes which has 
become due and payable solely by reason of such declaration under Section 8.2),
the Guaranty and under the Consolidated Collateral Documents shall have been 
duly paid and (iii) each and every other Event of Default shall have been 
cured or waived; and provided further, that no such rescission and annulment 
shall extend to or affect any subsequent Default or Event of Default or 
impair any right consequent thereto. 

          8.4.    Other Remedies.  If any Event of Default shall be continuing,
any Holder of Notes may enforce its rights by suit in equity, by action at law,
or by any other appropriate proceedings, whether for the specific performance
(to the extent permitted by law) of any covenant or agreement contained in this
Agreement or in the Notes or in aid of the exercise of any power granted in
this Agreement, and may enforce the payment of any Note held by such Holder and
any of its other legal or equitable rights. 

          8.5.    Conduct No Waiver; Collection Expenses.  No course of dealing
on the part of any Holder of Notes, nor any delay or failure on the part of any
Holder of Notes to exercise any of its rights, shall operate as a waiver of such
rights or otherwise prejudice such Holder's rights, powers and remedies. If the
Company fails to pay, when due, the principal of, Make-Whole Amount or the
interest on, any Note, or fails to comply with any other provision of this
Agreement, the Company will pay to each Holder, to the extent permitted by law,
on demand, such further amounts as shall be sufficient to cover the cost and
expenses, including but not limited to reasonable attorneys' fees, incurred by
such Holders of the Notes in collecting any sums due on the Notes or in
otherwise enforcing any of their rights. 

          8.6.    Remedies Cumulative.  No right or remedy conferred upon or
reserved to any Holder of Notes under this Agreement is intended to be
exclusive of any other right or remedy, and every right and remedy shall be
cumulative and in addition to every other right or remedy given under this
Agreement or now or hereafter existing under any applicable law.  Every right
and remedy given by this Agreement or by applicable law to any Holder of Notes
may be exercised from time to time and as often as may be deemed expedient by
such Holder, as the case may be. 

          8.7.    Notice of Default.  With respect to Defaults or Events of 
Default, the Company will give the following notices:

         (a)     The Company promptly, but in any event within 5 days, will
furnish to each Holder written notice of the occurrence of a Default or an
Event of Default.  Such notice shall specify the nature of such default, the
period of existence thereof and what action the Company has taken or is taking
or proposes to take with respect thereto.


                                       26
<PAGE>   28

         (b)     If the Holder of any Note or of any other evidence of
Indebtedness of the Company or any Subsidiary gives any notice or takes any
other action with respect to a claimed default, the Company will forthwith give
written notice thereof to each Holder of the then outstanding Notes, describing
the notice or action and the nature of the claimed default.  


Section 9.  AMENDMENTS, WAIVERS AND CONSENTS

         9.1.    Matters Subject to Modification.  Any term, covenant,
agreement or condition of this Agreement may, with the consent of the Company,
be amended, or compliance therewith may be waived (either generally or in a
particular instance and either retroactively or prospectively), if the Company
shall have obtained the consent in writing of the Holder or Holders of at least
66-2/3% in aggregate principal amount of outstanding Notes; provided, however,
that, without the written consent of the Holder or Holders of all of the Notes
then outstanding, no such waiver, modification, alteration or amendment shall
be effective which will (i) change the time of payment (including any required
prepayment) of the principal of or the interest on any Note, (ii) reduce the
principal amount thereof or the Make-Whole Amount, if any, or reduce the rate
of interest thereon, (iii) change any provision of any instrument affecting the
preferences among Holders of the Notes or between Holders of the Notes and
other creditors of the Company, or (iv) change any of the provisions of Section
8.1, Section 8.2, Section 8.3 or this Section 9.

         For the purpose of determining whether Holders of the requisite
principal amount of Notes have made or concurred in any waiver, consent,
approval, notice or other communication under this Agreement, Notes held in the
name of, or owned beneficially by, the Company, any Subsidiary or any Affiliate
thereof, shall not be deemed outstanding.

         9.2.    Solicitation of Holders of Notes.  The Company will not
solicit, request or negotiate for or with respect to any proposed waiver or
amendment of any of the provisions of this Agreement or the Notes unless each
Holder of the Notes (irrespective of the amount of Notes then owned by it)
shall concurrently be informed thereof by the Company and shall be afforded the
opportunity of considering the same and shall be supplied by the Company with
sufficient information to enable it to make an informed decision with respect
thereto.  Executed or true and correct copies of any waiver or consent effected
pursuant to the provisions of this Section 9 shall be delivered by the Company
to each Holder of outstanding Notes forthwith following the date on which the
same shall have been executed and delivered by the Holder or Holders of the
requisite percentage of outstanding Notes.  The Company will not, directly or
indirectly, pay or cause to be paid any remuneration, whether by way of
supplemental or additional interest, fee or otherwise, to any Holder of the
Notes as consideration for or as an inducement to the entering into by any
Holder of the Notes of any waiver or amendment of any of the terms and
provisions of this Agreement unless such remuneration is concurrently paid, on
the same terms, ratably to each Holder of the then outstanding Notes.

         9.3.    Binding Effect.  Any such amendment or waiver shall apply
equally to all the Holders of the Notes and shall be binding upon them, upon
each future Holder of any Note and upon the Company whether or not such Note
shall have been marked to indicate such amendment or waiver.  No such amendment
or waiver shall extend to or affect any obligation not expressly amended or
waived or impair any right related thereto.

Section 10.      FORM OF NOTES, REGISTRATION, TRANSFER, EXCHANGE AND REPLACEMENT

         10.1.   Form of Notes.  The Notes to be delivered under this Agreement
will be in the form of fully registered Notes in the form attached as Exhibit
A.  The Notes are issuable only in fully registered form and in denominations
of at least $100,000 (or the remaining outstanding balance thereof, if less
than $100,000).

         10.2.   Note Register.  The Company shall cause to be kept at its
principal office a register (the "Note Register") for the registration and
transfer of the Notes.  The names and addresses of the Holders of Notes, the
transfer thereof and the names and addresses of the transferees of the Notes
shall be registered in the Note Register.  The Company may deem and treat the
Person in whose name a Note is so registered as the Holder and owner thereof
for all purposes and shall not be affected by any notice to the contrary, until
due presentment of such Note for registration of transfer as provided in this
Section 10.

         10.3.   Issuance of New Notes upon Exchange or Transfer.  Upon
surrender for exchange or registration of transfer of any Note (including any
Outstanding Note) at the office of the Company designated for notices in
accordance with Section 11.2, the Company shall execute and deliver, at its
expense, one or more new Notes of any authorized denominations requested by the
Holder of the surrendered Note (including any Outstanding Note), each dated the
date to which interest has been paid on the Notes so surrendered (or, if no
interest has been paid, the date of such surrendered Note), but in the same
aggregate unpaid principal amount as such surrendered Note (including any
Outstanding Note), and registered in the name of such Person or Persons 

                                       27
<PAGE>   29



as shall be designated in writing by such Holder.  Every Note (including any
Outstanding Note) surrendered for registration of transfer shall be duly
endorsed, or be accompanied by a written instrument of transfer duly executed,
by the Holder of such Note or by his attorney duly authorized in writing.  The
Company may condition its issuance of any new Note (other than upon surrender
of an Outstanding Note) in connection with a transfer by any Person on
compliance with Section 3.2, by Institutional Holders on compliance with
Section 2.5 and on the payment to the Company of a sum sufficient to cover any
stamp tax or other governmental charge imposed in respect of such transfer.

         10.4.   Replacement of Notes.  Upon receipt of evidence satisfactory
to the Company of the loss, theft, mutilation or destruction of any Note
(including any Outstanding Note), and in the case of any such loss, theft or
destruction upon delivery of a bond of indemnity in such form and amount as
shall be reasonably satisfactory to the Company or in the event of such
mutilation upon surrender and cancellation of the Note (including any
Outstanding Note), the Company, without charge to the Holder thereof, will make
and deliver a new Note, of like tenor in lieu of such lost, stolen, destroyed
or mutilated Note (including any Outstanding Note).  If any such lost, stolen
or destroyed Note (including any Outstanding Note) is owned by you or any other
Institutional Holder, then the affidavit of an authorized officer of such owner
setting forth the fact of loss, theft or destruction and of its ownership of
the Note (including any Outstanding Note) at the time of such loss, theft or
destruction shall be accepted as satisfactory evidence thereof, and no further
indemnity shall be required as a condition to the execution and delivery of a
new Note, other than a written agreement of such owner (in form reasonably
satisfactory to the Company) to indemnify the Company.  

Section 11. MISCELLANEOUS

         11.1.   Expenses.  Whether or not the transactions herein contemplated

Collateral Documents, the Registration Agreement, the Notes or the Common 
Shares (but not in connection with a transfer of any Notes or any Common 
Shares), whether or not any Notes are then outstanding.  The obligations of

judicial or administrative proceeding (whether or not the original is in
existence and whether or not such reproduction was made by you in the regular
course of business) and that any enlargement, facsimile or further reproduction
of such reproduction shall likewise be admissible in evidence; provided that
nothing herein contained shall preclude the Company from objecting to the
admission of any reproduction on the basis that such reproduction is not

representations and warranties made by the Company herein and in any
certificates delivered pursuant to this Agreement, the Guaranty, the
Registration Agreement, or the Consolidated Collateral Documents, whether or

                USA WASTE SERVICES AND CHAMBERS DEVELOPMENT COMPANY
                        ANNOUNCE DEFINITIVE MERGER AGREEMENT

        Dallas, Texas (November 28, 1994)--USA Waste Services, Inc.
(NYSE--"UW") and Chambers Development Company, Inc. (AMEX: "CDVA/CDVB") jointly
announced today the execution of a definitive agreement providing for the
merger of Chambers into USA Waste. Under the terms of the merger agreement, USA
Waste will issue 0.41667 shares of its common stock for each share of Chambers'
Class A common stock and common stock outstanding, subject to certain
adjustments. In the aggregate, USA Waste will issue approximately 27.8 million
shares of its common stock in connection with the merger. Based on USA Waste's
closing price on November 25, 1994, of $14.00 and taking into account Chambers'
existing indebtedness, the transaction has a total value of approximately $725
million.

        As a result of the merger, USA Waste will be the fourth largest solid
waste company in North America, with annual revenues of approximately $450
million. It will have operations in 21 states, including 25 municipal solid
waste landfills with permitted capacity in excess of 340 million cubic yards of
air space, 37 collection companies and 13 transfer stations.

        The management team will be led by John E. Drury of USA Waste, as
Chairman and Chief Executive Officer. Donald F. Moorehead, Jr., of USA Waste
and John G. Rangos, Sr., of Chambers, will serve as Vice-Chairmen of the Board
of Directors. Mr. Moorehead will also function as USA Waste's Chief Development
Officer. David Sutherland-Yoest, USA Waste's President and Chief Operating
Officer, and Earl E. DeFrates, USA Waste's Chief Financial Officer, will
continue to serve in their current positions. Alexander W. Rangos will serve as
a Board member and will join USA Waste as Executive Vice President.

        "Chambers has some of the finest landfill assets in North America,"
said Mr. Drury, "and we believe the combination of the two companies will
provide significant benefits to both shareholder groups. Our strong waste
collection operations coupled with Chambers' exceptional landfill properties
will provide significant operating leverage to the combined asset base."
        
        John Rangos, Sr., Chambers' Chairman and Chief Executive Officer,
stated, "The combination of Chambers and USA Waste creates a strong, vibrant
entity that is capable of participating in the continuing consolidation that is
occurring in the solid waste industry. I believe this merger will serve the
best interests of our respective shareholders."

        The closing of the merger is subject to, among other things, the
receipt by each party of an opinion from its investment banking firm relating
to the financial fairness of the merger to its shareholders, approval of both
companies' shareholders, appropriate assurances as to the treatment of the
merger as a tax free reorganization accounted for as a pooling of interests,
Hart Scott-Rodino clearance, final settlement of certain litigation

affecting Chambers, and certain other conditions. If the conditions to the
closing of the merger are satisfied, the merger is expected to be consummated
in approximately six months.

        In connection with the merger agreement, USA Waste has received proxies
from certain of Chambers' shareholders authorizing USA Waste to vote such
shares in favor of the merger. The shares covered by these proxies represent a
majority of the total voting rights outstanding.

        Chambers has also received proxies from certain of USA Waste's
shareholders authorizing Chambers to vote such shares in favor of the merger.

        On November 19, 1994, Chambers announced that it had executed memoranda
of understanding relating to the settlement of its long-standing class action
litigation and had recorded a third quarter charge of approximately $74 million
to provide for such settlement.

        USA Waste Services, headquartered in Dallas, Texas, is a rapidly
growing, non-hazardous solid waste management company, performing both waste
collection and disposal services in multiple locations nationwide.

        Chambers Development Company, headquartered in Pittsburgh,
Pennsylvania, is a leading environmental services firm involved in landfill,
transfer station and recycling operations, as well as the collection,
transportation and hauling of residential, commercial, non-hazardous industrial
and medical wastes.
