ITEM 5. Other Events.
        -------------

     On August 17, 1998, Eastern Environmental Services, Inc. (NASDAQ: EESI)
("Eastern") announced that, pursuant to the terms of a definitive agreement and
plan of merger (the "Merger Agreement"), attached hereto as Exhibit 2.1, Waste
Management, Inc. (NYSE:WMI) ("Waste Management") has agreed to acquire Eastern
in a transaction whereby a wholly-owned subsidiary of Waste Management will be
merged with and into Eastern ("Merger").  In the Merger, holders of Eastern's
outstanding common stock will receive 0.6406 of a share of Waste Management
common stock in exchange for each share of Eastern common stock held, and
Eastern will become a wholly-owned subsidiary of Waste Management.

     In connection with, and as a condition to entering into the Merger
Agreement, Waste Management required that Louis D. Paolino, Jr., Chairman, CEO
and President of Eastern, George O. Moorehead, Director, Willard Miller,
Executive Vice President, Glen Miller, Executive Vice President, Gregory M.
Krzemien, Chief Financial Officer, and Robert M. Kramer, Executive Vice
President and General Counsel, enter into a Stockholders Support Agreement (the
"Support Agreement"), a form of which is attached hereto as Exhibit 2.2,
pursuant to which they are to vote in favor of and otherwise support the Merger,
subject to the limitations set forth therein.

     The Merger is subject to Eastern stockholder approval and customary closing
conditions, including government approvals.

     On August 19, 1998, a complaint (the "Complaint"), purporting to be a class
action, was filed in Delaware Chancery Court, naming certain Eastern directors
and Eastern as defendants and seeking to enjoin consummation of the Merger and
compensatory damages.  The Complaint alleges generally that Eastern directors
breached their fiduciary duties to Eastern stockholders.  A copy of the
Complaint is attached hereto as Exhibit 99.1.  Eastern believes that the
allegations in the Complaint are without merit and intends to vigorously defend
the case.

     The foregoing descriptions of the Merger Agreement, the Support Agreement,
the Complaint and the other matters set forth above are qualified in their
entirety by reference to the Exhibits hereto.

                       ------------------------------------------

<PAGE>
 
                                       3

          (a) each share of the common stock, par value $.01 per share, of the
     Company (the "Company Common Stock") shall, subject to Sections 3.3 and
                   --------------------                                     
     3.4, be converted into the right to receive, without interest, 0.6406 (the
     "Exchange Ratio") shares of the common stock, par value $.01 per share, of
      --------------                                                           
     Parent ("Parent Common Stock");
              -------------------   

          (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 canceled and no consideration shall be paid in exchange therefor and
     shall cease to exist from and after the Effective Time; and

          (c) each unexpired warrant 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 a warrant 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 warrant multiplied by the Exchange Ratio, at a price
     per share of Parent Common Stock equal to the per share exercise price of
     such warrant divided by the Exchange Ratio.

          Section 3.2  Conversion of Subsidiary Shares.  At the Effective Time,
                       -------------------------------

converted into one share of common stock, par value $.01 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 or
other distributions 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 other distributions 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 or other distributions 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.
<PAGE>
 
                                       4

          (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 applicable transfer or other taxes required by reason of such issuance.

          (c) Within five days 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) Within five days after the Effective Time, Parent shall cause the
Exchange Agent to 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 letter of transmittal
                           --------------------                              
satisfactory to the Company and approved by it prior to Closing (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 be canceled.  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 Time, 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 shares
of Company Common Stock for any shares of Parent Common Stock delivered to a
public official pursuant to applicable abandoned property, escheat or similar
laws.

                                       5

          (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 issuance 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
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 Shares.  (a)  No certificates or scrip
                       --------------------                                
representing fractional shares of Parent Common Stock shall be issued upon the
surrender for exchange of Company Certificates, no dividend or distribution with
respect to Parent Common Stock shall be payable on or with respect to any
fractional share and such fractional share interests will not entitle the owner
thereof to any rights of a stockholder of Parent.

          (b) As promptly as practicable following the Effective Time, the
Exchange Agent shall determine the excess of (x) the number of full shares of
Parent Common Stock delivered to the Exchange Agent by Parent over (y) the
aggregate number of full shares of Parent Common Stock to be distributed to
holders of Company Common Stock (such excess being herein called the "Excess
                                                                      ------
Shares").  As soon after the Effective Time as practicable, the Exchange Agent,
- ------                                                                         
as agent for such holders of Parent Common Stock, shall sell the Excess Shares
at then prevailing prices on the New York Stock Exchange, Inc. (the "NYSE"), all
                                                                     ----       
in the manner provided in paragraph (c) of this Section 3.4.

          (c) The sale of the Excess Shares by the Exchange Agent shall be
executed on the NYSE through one or more member firms of the NYSE and shall be
executed in round lots to the extent practicable.  The Exchange Agent shall use
all reasonable efforts to complete the sale of the Excess Shares as promptly
following the Effective Time as, in the Exchange Agent's reasonable judgment, is
practicable consistent with obtaining the best execution of such sales in light
of prevailing market conditions.  Until the net proceeds of any such sale or
sales have been distributed to such holders of Company Common Stock, the
Exchange Agent will hold such proceeds in trust for such holders of Company
Common Stock.  Parent shall pay all commissions, transfer taxes and other out-
of-pocket transaction costs of the Exchange Agent incurred in connection with
such sale or sales of Excess Shares.  In addition, Parent shall pay the Exchange
Agent's compensation and expenses in connection with such sale or sales.  The
Exchange Agent shall determine the portion of such net proceeds to which each
holder of Company Common Stock shall be entitled, if any, by multiplying the
amount of the aggregate net proceeds by a fraction the numerator of which is the
amount of the fractional 
<PAGE>
 
                                       6

share interest to which such holder of Company Common Stock is entitled (after
taking into account all shares of Company Common Stock then held by such holder)
and the denominator of which is the aggregate amount of fractional share
interests to which all holders of Certificates representing Company Common Stock
are entitled.

          (d) Notwithstanding the provisions of this Section 3.4, Parent may
elect, at its option exercised prior to the Effective Time and in lieu of the
issuance and sale of Excess Shares and the making of the payments contemplated
in such subsections, to pay to the Exchange Agent an amount in cash sufficient
for the Exchange Agent to pay each holder of Company Common Stock an amount in
cash equal to the product obtained by multiplying (x) the fractional share
interest to which such holder would otherwise be entitled (after taking into
account all shares of Company Common Stock held at the Effective Time by such
holder) by (y) the closing price for a share of Parent Common Stock on the NYSE
on the first business day immediately following the Effective Time and, in such
case, all references herein to the cash proceeds of the sale of the Excess
Shares and similar references shall be deemed to mean and refer to the payments
calculated as set forth in this Section 3.4(d)).

          (e) As soon as practicable after the determination of the amount of
cash, if any, to be paid to holders of Company Common Stock with respect to any
fractional share interests, the Exchange Agent shall promptly pay such amounts
to such holders of Company Common Stock.

          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 as promptly as practicable (but in any event within
five business days) 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 3.1 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 shares of Company Common Stock are presented to the Surviving
Corporation, they shall be canceled and exchanged for shares of Parent Common
Stock in accordance with this Article III.

                                  ARTICLE IV

            REPRESENTATIONS AND WARRANTIES OF PARENT AND SUBSIDIARY

          Parent and Subsidiary each represent and warrant to the Company that:

          Section 4.1  Organization and Qualification.  Each of Parent and
                       ------------------------------                     
Subsidiary is a corporation duly organized, validly existing and in good
standing under the laws of the state of its incorporation and has the requisite
power and authority to own, lease and operate its assets and properties and to
carry on its business as it is now being conducted.  Each of Parent and
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) or
results of operations of Parent and its subsidiaries, taken as a whole.  True,
accurate and complete copies of each of Parent's and Subsidiary's charters and
By-laws, in each case as in effect on the date hereof, including all amendments
thereto, have heretofore been delivered to the Company.

          Section 4.2  Capitalization.  (a)  As of August 10, 1998, the
                       --------------                                  
authorized capital stock of Parent consisted of 1,500,000,000 shares of Parent
Common Stock and 10,000,000 shares of preferred stock, par value $.01 per share
("Parent Preferred Stock").  As of August 10, 1998, (i) 579,687,096 shares of
  ----------------------                                                     
Parent Common Stock were issued and outstanding, all of which were validly
issued and are fully paid, nonassessable and free of preemptive rights, (ii) no
shares of Parent Preferred Stock were issued and outstanding, (iii) 23,485
shares of Parent Common Stock and no shares of Parent Preferred Stock were held
in the treasury of Parent, (iv) 37,600,799 shares of Parent Common Stock were
reserved for issuance upon exercise of outstanding options and warrants to
purchase Parent Common Stock and (v) 31,552,845 shares of Parent Common Stock
were reserved for issuance upon conversion of outstanding convertible debentures
and outstanding convertible notes.  Assuming the conversion of all outstanding
convertible debentures and outstanding convertible notes of Parent and the
exercise of all outstanding options, warrants and rights to purchase Parent
Common Stock, as of August 10, 1998, there would be 648,840,740 shares of Parent
Common Stock issued and outstanding.  In addition, as of the date hereof, no
more than 12,373,067 shares of Parent Common Stock were reserved for issuance in
connection with pending acquisitions.

          (b) The authorized capital stock of Subsidiary consists of 1,000
shares of Subsidiary Common Stock, of which 100 shares are issued and
outstanding, which shares are owned beneficially and of record by Parent.

Section 4.5) or in Section 4.2(a) or as otherwise contemplated by this
Agreement, as of the date hereof, there 
<PAGE>
 
                                       8

are no outstanding subscriptions, options, calls, contracts, commitments,
understandings, restrictions, arrangements, rights or warrants, including any
right of conversion or exchange under any outstanding security, instrument or
other agreement and also including any rights plan or other anti-takeover
agreement, obligating Parent or any subsidiary of Parent to issue, deliver or
sell or repurchase or redeem, or cause to be issued, delivered or sold,
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
commitment. Except as otherwise disclosed in the Parent SEC Reports, there are
no voting trusts, proxies or other agreements or understandings to which Parent
or any subsidiary of Parent is a party or is bound with respect to the voting of
any shares of capital stock of Parent, other than voting agreements executed in
connection with this Agreement. The shares of Parent Common Stock issued to
stockholders of the Company in the Merger will be at the Effective Time duly
authorized, validly issued, fully paid and nonassessable, free of preemptive
rights and will be issued in compliance with all applicable securities and other
laws.

          Section 4.3  Subsidiaries.  Each direct and indirect corporate
                       ------------                                     
subsidiary of Parent is duly organized, validly existing and in good standing
under the laws of its jurisdiction of incorporation and has the requisite power
and authority to own, lease and operate its assets and properties and to carry
on its business as it is now being conducted and 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 in all cases 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) or
results of operations 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,
encumbrances, security interests, equities and options of any nature whatsoever,
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 or interest in any
subsidiary of Parent, including any right of conversion or exchange under any
outstanding security, instrument or agreement.  As used in this Agreement, the
term "subsidiary" shall mean, when used with reference to any person or entity,
any corporation, partnership, joint venture or other entity 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.

          Section 4.4  Authority; Non-Contravention; Approvals.  (a)  Parent and

consummate the transactions contemplated hereby. This Agreement has been
approved by the Boards of Directors of Parent and Subsidiary and the sole
stockholder of Subsidiary, and no other corporate proceedings on the part of
Parent or Subsidiary are necessary to authorize the execution and delivery of
this Agreement or, the consummation by Parent and Subsidiary of the transactions
contemplated hereby. This Agreement has been duly executed and delivered by each
of Parent and Subsidiary, and, assuming the due authorization, execution and
delivery hereof by the Company, constitutes a valid and legally binding
agreement of each of Parent and Subsidiary enforceable against each of them in
accordance 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.

          (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
accelerate the performance required by, or result in a right of termination or
acceleration under, or result in the creation of any lien, security interest,

assets or (iii) any note, bond, mortgage, indenture, deed of trust, license,
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

foregoing sentences of this paragraph (b), insofar as they apply to the terms,
conditions or provisions described in clauses (ii) and (iii) of the first
sentence of this paragraph (b) (and whether resulting from such execution and
delivery or consummation), are such violations, conflicts, breaches, defaults,
terminations, accelerations or creations of liens, security interests, charges
or encumbrances that would not, in the aggregate, have a material adverse effect
on the business, operations, properties, assets, condition (financial or other)
or results of operations of Parent and its subsidiaries, taken as a whole.

subsidiaries has good and marketable title in fee simple to all its real
property and good title to all its leasehold interests and other properties, as
reflected in the most recent balance sheet included in the Company Financial
Statements, except for properties and assets that have been disposed of in the
ordinary course of business since the date of such balance sheet, free and clear
of all mortgages, liens, pledges, charges or encumbrances of any nature
whatsoever, except (i) the lien for current taxes, payments of which are not yet
delinquent, (ii) such imperfections in title and easements and encumbrances, if
any, as are not substantial in character, amount or extent and do not materially
detract from the value, or interfere with the present use of the property
subject thereto or affected thereby, or otherwise materially impair the
Company's business operations (in the manner presently carried on by the
Company) or (iii) as disclosed in the Company SEC Reports, and except for such
matters which, singly or in the aggregate, could not reasonably be expected to
materially and adversely affect the business, operations, properties, assets,
condition (financial or other) or results of operations of the Company and its
subsidiaries, taken as a whole.  All leases under which the Company leases any
real or personal property are in good standing, valid and effective in
accordance with their respective terms, and there is not, under any of such
leases, any existing default or event which with notice or lapse of time or both
would become a default other than failures to be in good standing, valid and
effective and defaults under such leases which in the aggregate will not
materially and adversely affect the business, operations, properties, assets,
condition (financial or other) or results of operations of the Company and its
subsidiaries, taken as a whole.

                        ---------------------------------------         
knowledge of the Company, neither the Company nor any of its affiliates has
taken or agreed or intends to take any action or has any knowledge of any fact
or circumstance that would prevent the Merger from (a) constituting a
reorganization within the meaning of Section 368(a) of the Code or (b) being
treated for financial accounting purposes as a Pooling Transaction.  As of the
date hereof, other than directors and officers of the Company, to the knowledge
of the Company, there are no "affiliates" of the Company, as that term is used
in paragraphs (c) and (d) of Rule 145 under the Securities Act.

          Section 5.19  Company Stockholders' Approval.  The affirmative vote of
                        ------------------------------                          
stockholders of the Company required for approval and adoption of this Agreement
and the Merger is a majority of the outstanding shares of Company Common Stock
entitled to vote thereon.

payable to Salomon Smith Barney, which fees are reflected in its agreement with
the Company, the Company has not entered into any contract, arrangement or
understanding with any person or firm which may result in the obligation of the
Company to pay any finder's fees, brokerage or agent commissions or other like
payments in connection with the transactions contemplated hereby.  Except for
the fees and expenses paid or payable to Salomon Smith Barney, there is no claim
<PAGE>
 
                                       26

for payment by the Company of any investment banking fees, finder's fees,
brokerage or agent commissions or other like payments in connection with the
negotiations leading to this Agreement or the consummation of the transactions
contemplated hereby.

          Section 5.21  Opinion of Financial Advisor.  The financial advisor of
                        ----------------------------                           
the Company, Salomon Smith Barney, has rendered an opinion to the Board of
Directors of the Company to the effect that, as of the date thereof, the
Exchange Ratio is fair to the holders of Company Common Stock from a financial
point of view; it being understood and acknowledged by Parent and Subsidiary
that such opinion has been rendered for the benefit of the Board of Directors of
the Company and is not intended to, and may not, be relied upon by Parent, its
affiliates or their respective subsidiaries.

Except as otherwise permitted by Section 6.1 of the Company Disclosure Schedule
or otherwise contemplated by this Agreement, after the date hereof and prior to
the Closing Date or earlier termination of this Agreement, unless Parent shall
otherwise agree in writing, the Company shall, and shall cause its subsidiaries
to:

          (a) conduct their respective businesses in the ordinary and usual
     course of business and consistent with past practice;

          (b) not (i) amend or propose to amend their respective charter or by-
     laws (except that the Company may amend its charter to increase the number
     of authorized shares of Company Common Stock), (ii) split, combine or
     reclassify their outstanding capital stock or (iii) declare, set aside or
     pay any dividend or distribution payable in cash, stock, property or
     otherwise, except for the payment of dividends or distributions to the
     Company by a wholly-owned subsidiary of the Company;

          (c) not issue, sell, pledge or dispose of, or agree to issue, sell,
     pledge or dispose of, any additional shares of, or any options, warrants or
     rights of any kind to acquire any shares of their capital stock of any

     such capital stock, except that (i) the Company may issue shares upon
     exercise of options and warrants, (ii) the Company may issue shares of
     Company Common Stock (or warrants or options to acquire up to an aggregate

     of a share of Company Common Stock on the day prior to grant of such option
     with respect to up to an aggregate of 100,000 shares of Company Common
     Stock; provided, however, that such grants may not be made to any current
            --------  ------- 
     executive officer or director of the Company and may only be made in the
     ordinary course of business, to employees of the Company and its
     subsidiaries consistent with past practice; and (iv) after December 31,
     1998, the Company may issue options to executive officers and directors in
     an amount consistent with past practice and after delivery to Parent of a
     letter from Ernst & Young LLP in a form reasonably satisfactory to Parent
     to the effect that the issuance of such options would not prevent the
     Merger from being treated as a "pooling of interests" for financial
     accounting purposes.

          (d) not (i) incur or become contingently liable with respect to any
     indebtedness for borrowed money other than (A) borrowings in the ordinary
     course of business (other than pursuant to credit facilities) or borrowings
     under the existing credit facilities of the Company or any of its
     subsidiaries as such facilities may be amended in a manner that does not
     have a material adverse effect on the Company (the "Existing Credit
                                                         ---------------

     acquisitions or rollovers of certain leases of equipment in the ordinary
     course of business consistent with past practice in amount or (D)
     borrowings in connection with acquisitions as set forth in the proviso in
     this Section 6.1(d), (ii) redeem, purchase, acquire or offer to purchase or
     acquire any shares of its capital stock or any options, warrants or rights
     to acquire any of its capital stock or any security convertible into or
     exchangeable for its capital stock, (iii) notwithstanding any other
     provision of this Section 6.1, take any action that would jeopardize the
     treatment of the Merger as a pooling of interests under Opinion No. 16 of
     the Accounting Principles Board ("APB No. 16"), (iv) notwithstanding any
                                       ----------                            
     other provision of this Section 6.1, take or fail to take any action which
     action or failure to take action would cause the Company or its
     stockholders (except to the extent that any stockholders receive cash in
     lieu of fractional shares and except to the extent of Stockholders in
     special circumstances) to recognize gain or loss for federal income tax
     purposes as a result of the consummation of the Merger or would otherwise
     cause the Merger not to qualify as a reorganization under Section 368(a) of
     the Code, (v) make any acquisition of any assets or businesses other than

     business, (b) sales of businesses or assets disclosed in Section 6.1 of the
     Company Disclosure Schedule, (c) sales of businesses or assets with

     contract, agreement, commitment or arrangement with respect to any of the
     foregoing; provided, however, that notwithstanding the foregoing (other

     not be prohibited from acquiring any assets or businesses or incurring or
     assuming indebtedness in connection with acquisitions of assets or
     businesses so long as (A) such acquisitions are disclosed in Section 6.1 of
     the Company Disclosure Schedule, or (B) the aggregate revenue projected to

     those acquisitions disclosed in Section 6.1 of the Company Disclosure
     Schedule), including any funded indebtedness assumed and any Company Common
     Stock issued in connection with such acquisition (valued for purposes of
     this limitation at a price per share equal to the price of the Company
     Common Stock on the date the agreement in respect of such acquisition is
     entered into) does not exceed $60 million. For purposes of the foregoing,
     any contingent, royalty and similar payments made in connection with
     acquisitions of businesses or assets shall be included as acquisition
     consideration and shall be deemed to have a value equal to their present
     value assuming an 8% per annum discount rate and assuming that all amounts
     payable for the first five years following consummation of the acquisitions
     (but not thereafter) are paid. Notwithstanding anything herein to the
     contrary (A) the Company will not acquire or agree to acquire any assets or
     businesses if such acquisition or agreement may reasonably be expected to
     delay the consummation of the Merger, (B) the Company will not acquire or

     not in industries in which the Company currently operates, unless such
     assets or businesses are acquired incidental to an acquisition of
     businesses or assets that are in industries in which the Company currently
     operates and it is reasonable to acquire such incidental businesses or
     assets in connection with such acquisition, and (C) the Company will not
     acquire or agree to acquire all or substantially all of the business,

     or more representatives of Parent to report operational matters of
     materiality and the general status of ongoing operations;

          (g) not enter into or amend any employment, severance, special pay
     arrangement with respect to termination of employment or other similar

     generally, other than in the ordinary course of business, except (i) as
     contemplated by Section 6.1(c), (ii) as required to comply with changes in
     applicable law, (iii) to increase the number of shares of Company Common

     Stock Bonus Plan, (iv) any of the foregoing involving any such then
     existing plans, agreements, trusts, funds or arrangements of any company
     acquired after the date hereof or (v) as required pursuant to an existing

to Section 6.1(d)) whether for cash, securities or any other consideration or
combination thereof (any such transactions being referred to herein as an
"Acquisition Transaction").

Company may, in response to an unsolicited written offer or proposal with
respect to a potential or proposed Acquisition Transaction ("Acquisition

consummated pursuant to its terms) in an Acquisition Transaction more favorable
to the Company's stockholders than the Merger (any such offer or proposal being
referred to as a "Superior Proposal"), furnish (subject to the execution of a
                  -----------------

Directors of the Company, after consulting with its outside legal counsel,
determines in good faith that the failure to provide such confidential or
nonpublic information to or negotiate with such Potential Acquirer would be
reasonably likely to constitute a breach of its fiduciary duty to the Company's
stockholders and (ii) the Company's Board of Directors may take and disclose to
the Company's stockholders a position contemplated by Rule 14e-2 under the
Exchange Act.  It is understood and agreed that negotiations and other

or request for nonpublic information relating to the Company or its subsidiaries
in connection with an Acquisition Proposal or for access to the properties,
books or records of the Company or any subsidiary by any person or entity that
informs the Board of Directors of the Company or such subsidiary that it is
considering making, or has made, an Acquisition Proposal.  Such notice to Parent
shall be made orally and in writing and shall indicate in reasonable detail the
identity of the offeror and the terms and conditions of such proposal, inquiry
or contact.

Company shall each use its commercially reasonable efforts to cause each
officer, each director and each other person who is an "affiliate," as that term

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")
                                                           -------------------

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

the ultimate parent entity thereof), (ii) a sale, lease, exchange, transfer or
other disposition of more than 30% of the assets of the Company and its
subsidiaries, taken as a whole, in a single transaction or a series of related
transactions, or (iii) the acquisition, by a person (other than Parent or any
affiliate thereof), group or entity of beneficial ownership (as defined in Rule

                       ----------------------                                
conditions herein provided and subject to the fiduciary duties of the respective
boards of directors of the Company and Parent, 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 or approvals of third parties
required in order to preserve material contractual relationships of Parent and
the Company and their respective subsidiaries, 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).

          (b) Without limitation of the foregoing, each of Parent and the
Company undertakes and agrees to file as soon as practicable, and in any event
prior to 15 days 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) respond as promptly as practicable to any
<PAGE>
 
                                       35


inquiries received from the FTC or the Antitrust Division for additional
information or documentation and to all inquiries and requests received from any
State Attorney General or other governmental authority in connection with
antitrust matters 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 written consent of the other parties hereto.  Parent shall take all
reasonable steps necessary to avoid or eliminate impediments under any
antitrust, competition, or trade regulation law that may be asserted by the FTC,
the Antitrust Division, any State Attorney General or any other governmental
entity with respect to the Merger so as to enable the Closing to occur as soon
as reasonably possible.  Without limiting the foregoing, Parent shall propose,
negotiate, commit to and effect, by consent decree, hold separate order, or
otherwise, the sale, divestiture or disposition of such assets or businesses of
Parent or, effective as of the Effective Time, the Surviving Corporation as may
be required in order to avoid the entry of, or to effect the dissolution of, any
injunction, temporary restraining order or other order in any suit or
proceeding, which would otherwise have the effect of preventing or delaying the
Closing; provided, however, that Parent shall not be required to take any such
         --------  -------                                                    
actions if such action would be reasonably likely, in the aggregate, to have a
material adverse effect on the business, operations, properties, assets,
condition (financial or other) or results of operations of the Company and its
subsidiaries taken as a whole, in the case of a sale divestiture, holding
separate or other disposition of assets of the Company or its subsidiaries, or,
in the case of a sale, divestiture, holding separate or other disposition of
assets of the Parent or its subsidiaries, such action with respect to a
comparable amount of assets of the Company would be reasonably likely, in the
aggregate, to have such a material adverse effect.  Parent or the Company, as
applicable, shall take promptly, in the event that any permanent or preliminary
injunction or other order is entered or becomes reasonably foreseeable to be
entered in any proceeding that would make consummation of the transactions
contemplated hereby in accordance with the terms of this Agreement unlawful or
that would prevent or delay consummation of the transactions contemplated
hereby, any and all steps necessary to vacate, modify or suspend such injunction
or order so as to permit such consummation prior to the deadline specified in
Section 9.1(a)(ii) or Section 9.1(b)(ii).  The parties hereto will consult and
cooperate with one another, and consider in good faith the views of one another,
in connection with any analyses, appearances, presentations, memoranda, briefs,
arguments, opinions and proposals made or submitted by or in behalf of any party
hereto in connection with proceedings under or relating to the HSR Act or any
other federal, state or foreign antitrust or fair trade law.  The parties hereto
will provide to the other copies of all correspondence between it (or its
advisors) and the FTC, the Antitrust Division or any State Attorney General
relating to this Agreement or any of the matters described in this Section
7.7(b).  The parties hereto agree that all material telephonic calls and
meetings with the FTC, the Antitrust Division or any State Attorney General
regarding the transactions contemplated hereby or any of the matters described
in this Section 7.7(b) shall include representatives of each of Parent and the
Company.  Parent shall coordinate and be the principal spokesperson in
connection with any proceedings or negotiations with any

                                       36

governmental entity relating to any of the foregoing, provided that it shall
afford the Company a reasonable opportunity to participate therein.

          (c) In the event any litigation is commenced by any person or entity
relating to the transactions contemplated by this Agreement, or any Acquisition
Transaction, Parent shall have the right, at its own expense, to participate
therein, and the Company will not settle any such litigation without the consent
of Parent, which consent will not be unreasonably withheld.

          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.  (a)  The Company shall use commercially
                       ------------                                          
reasonable efforts and shall take all necessary actions, including but not
limited to obtaining the consent of the option holders, if necessary, to ensure
that, at the Effective Time, all rights with respect to the Company Common Stock
pursuant to each stock option ("Company Options") granted under stock option
                                ---------------                             
plans of the Company or otherwise which is outstanding on the Effective Date,
whether or not such Company Option has previously vested or become exercisable,
shall be cancelled in exchange for a number of shares of Parent Common Stock
equal in market value (based upon the average of the closing prices of the
Parent Common Stock on the NYSE for the 10 trading days immediately prior to the
Closing Date) to the fair value of such Company Option as determined by
independent third party experts, mutually agreed upon by Parent and the Company.
The parties hereto have agreed that the value determined using the methodology
proposed by such independent third party experts will represent the fair value
of the Company Options as of the Effective Time.

          (b) At the Effective Time, automatically and without any action on the
part of the holder thereof, each outstanding Company Option that was not
canceled in accordance with Section 7.9(a) above shall be assumed by Parent and
become an option to purchase that number of shares of Parent Common Stock
obtained by multiplying the number of shares of Company Common Stock issuable
upon the exercise of such option by the Exchange Ratio at an exercise price per
share equal to the per share exercise price of such option divided by the
Exchange Ratio, and otherwise upon the same terms and conditions as such
outstanding Company Options; provided, however, that in the case of any Company
                             --------  -------                                 
Option to which Section 421 of the Code applies by reason of the qualifications
under Section 422 or 423 of such Code, the exercise price, the number of shares
purchasable pursuant to such Company Option be determined in order to comply
with Section 424(a) of the Code.

          (c) Parent shall take all corporate actions necessary to reserve for
issuance a sufficient number of shares of Parent Common Stock for delivery upon
exercise of the Company Options assumed by Parent, if any, pursuant to Section
7.9(b) above.

          (d) As promptly as practicable after the Effective Time, Parent shall
file a Registration Statement on Form S-8 (or any successor or other appropriate
forms) with respect to the shares of Parent Common Stock subject to the Company
Options and shall use its reasonable efforts to maintain the effectiveness of
such registration statement or registration statements (and maintain the current
status of the prospectus or prospectuses contained therein) for so long as such
Company Options remain outstanding.

          (e) Except as provided herein or as otherwise agreed to by the
parties, each of the Company stock option plans providing for the issuance or
grant of Company Options shall be assumed as of the Effective Time by Parent
with such amendments thereto as may be required to reflect the Merger.

          Section 7.10  Notification of Certain Matters.  Each of the Company,
                        -------------------------------                       
Parent and Subsidiary agrees to give prompt notice to each other of, and to use
commercially reasonable efforts to remedy, (i) the occurrence or failure to
occur of any event which occurrence or failure to occur would be likely to cause
any of its representations or warranties in this Agreement to be untrue or
inaccurate in any material respect at 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 7.10 shall not limit or
otherwise affect the remedies available hereunder to the party receiving such
notice.

          Section 7.11  Directors' and Officers' Indemnification.  (a)  The
                        ----------------------------------------           
indemnification provisions of the Certificate of Incorporation and By-Laws of
the Surviving Corporation as in effect at the Effective Time shall not be
amended, repealed or otherwise modified for a period of six years from the
Effective Time in any manner that would adversely affect the rights thereunder
of individuals who at the Effective Time were directors, officers, employees or
agents of the Company.  Parent shall assume, be jointly and severally liable
for, and honor, guaranty and stand surety for, and shall cause the Surviving
Corporation to honor, in accordance with their respective terms each of the
covenants contained in this Section 7.11 and each of the indemnification
agreements listed on Section 7.11 of the Company Disclosure Schedule without
limit as to time; provided, however, in the event of a conflict between the
                  --------  -------                                        
provisions of this Section 7.11 and the provisions of an indemnification
agreement listed on Section 7.11 of the Company Disclosure Schedule, the
provisions of such indemnification agreement shall govern.

          (b) After the Effective Time, each of Parent and 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 actual or
threatened claim, action, suit, proceeding or investigation, whether civil,
criminal, administrative or investigative, arising out of, relating to or in
<PAGE>
 
                                       38

connection with any action or omission occurring or alleged to occur prior to
the Effective Time (including, without limitation, acts or omissions in
connection with this Agreement and the consummation of transactions contemplated
hereunder and 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
actual or threatened 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 and shall pay all other reasonable
expenses in advance of the final disposition of such action, (ii) the Parent and
the Surviving Corporation will cooperate and use all reasonable efforts to
assist in the vigorous defense of any such matter, and (iii) to the extent any
determination is 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 charters or by-laws such
determination 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 the Parent nor the Surviving Corporation
       --------  -------                                                       
shall be liable for any settlement effected without its written consent (which
consent shall not be unreasonably withheld) and provided further that if Parent
or the Surviving Corporation advances or pays any amount to any person under
this paragraph (b) and if it shall thereafter be finally determined by a court
of competent jurisdiction that such person was not entitled to be indemnified
hereunder for all or any portion of such amount, to the extent required by law,
such person shall repay such amount or such portion thereof, as the case may be,
to Parent or the Surviving Corporation, as the case may be.  The indemnified
Parties as a group may not retain more than one law firm to represent them with
respect to each matter unless there is, under applicable standards of
professional conduct, a conflict on any significant issue between the positions
of any two or more indemnified Parties.

          (c) 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 Surviving
Corporation or Parent shall assume the obligations of the Surviving Corporation
or the Parent, as the case may be, as set forth in this Section 7.11.

          (d) For a period of six years after the Effective Time, Parent shall
cause to be maintained in effect the current policies of directors' and
officers' liability insurance maintained by the Company and its subsidiaries
(provided that Parent may substitute therefor policies of at least the same
coverage and amounts containing terms and conditions that are no less
advantageous to the indemnified Parties and which coverages and amounts shall be
no less than the coverages and amounts provided at that time for Parent's
directors and officers provided that there shall be no lapse of coverage) with
respect to matters arising on or before the Effective Time and acts or 
<PAGE>
 
                                       39

omissions in connection with this Agreement and the consummation of the
transactions contemplated hereunder.

          (e) Parent shall pay all reasonable expenses, including reasonable
attorneys' fees, that may be incurred by any indemnified Party in enforcing the
indemnity and other obligations provided in this Section 7.11.

          (f) The rights of each indemnified Party hereunder shall be in
addition to, and not in limitation of, any other rights such indemnified Party
may have under the charter or bylaws of the Company, any indemnification
agreement, under the DGCL or otherwise.  The provisions of this Section 7.11
shall survive the consummation of the Merger and expressly are intended to
benefit each of the indemnified Parties.

          Section 7.12  Corrections to the 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
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 Proxy Statement/Prospectus or the Registration
Statement so as to correct the same and to cause the 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.

          Section 7.13.  Assumption of Registration Rights Agreements.    The
                         --------------------------------------------        
Company will use reasonable best efforts to ensure that Parent and Subsidiary
shall have no obligation to register any securities of the Surviving Corporation
after the Effective Time.

          Section 7.14.  Company Employees.  Prior to the Effective Time,
                         -----------------                               
neither Parent nor any subsidiary of Parent or any affiliate of Parent or any of
its subsidiaries shall offer to employ or employ any salaried managerial or
professional employee of Company or any of its subsidiaries, if such employment
would begin prior to the Effective Time, without the prior written consent of
Company.

BARBARA SELVERIAN,
                                               Civil Action No. 1659INC
         Plaintiff,

    v.

LOUIS D. PAOLINO, JR.; GEORGE
O. MOOREHEAD; KENNETH CHUAN-KAI
LEUNG and EASTERN ENVIRONMENTAL
SERVICES, INC.,

         Defendants

                                   COMPLAINT
                                   ---------

     Plaintiff, by her attorneys, alleges upon information and belief, except as
to paragraph 1 which is alleged upon personal knowledge, as follows:

                                  THE PARTIES
                                  -----------

      1.  Plaintiff Barbara Selverian is the owner of common stock of Eastern 
Environmental Services, Inc. ("Eastern" or the "Company") and has been the owner
of such shares continuously since prior to the wrongs complained of herein.

      2.  Defendant Eastern is a corporation duly existing  and organized under 
the laws of the State of Delaware, with its principal offices located at 1000 
Crawford Place, Suite 400, Mount Laurel, New Jersey. Eastern is a waste services
company specializing in the collection, transportation, and disposal of 
nonhazardous residential, commercial, and industrial waste.

      3.  Defendant Louis D. Paolino ("Paolino") is and at all times relevant 
hereto has been Chief Executive Officer and Chairman of the Board of Directors 
of Eastern.
<PAGE>
 
     4.   Defendant George O. Moorehead ("Moorehead") is and at all times 
relevant hereto has been a director of Eastern.

     5.   Defendant Kenneth Chuan-kai Leung ("Leung") is and at all times 
relevant hereto has been a director of Eastern.

     6.   Defendants Paolino, Moorehead, and Leung are collectively referred to 
herein as the "Individual Defendants."

     7.   By reason of the above Individual Defendants' positions with the 
Company as officers and/or directors, said individuals are in a fiduciary 
relationship with plaintiff and the other public stockholders of Eastern, and 
owe plaintiff and the other members of the class the highest obligations of 
good faith, fair dealing, due care, loyalty and full and candid disclosure.

                           CLASS ACTION ALLEGATIONS
                           ------------------------

     8.   Plaintiff brings this action on her own behalf and as a class action, 
pursuant to Rule 23 of the Rules of the Court of Chancery, on behalf of herself 
and all other holders of Eastern common stock (the "Class"). Excluded from the 
Class are defendants herein and any person, firm, trust, corporation or other 
entity related to or affiliated with any of the defendants.

     9.   This action is properly maintainable as a class action.

     10.  The Class is so numerous that joinder of all members is impracticable.
As of August 15, 1998, there were approximately 32.66 million shares of Eastern 
common stock outstanding.

                                      -2-
<PAGE>
 
  11. There are questions of law and fact which are common to the Class and 
which predominate over questions affecting any individual Class members. The 
common questions include, inter alia, the following:
                          ----------      
    (a) whether the merger is grossly unfair to the Class;

    (b) whether plaintiff and the other members of the Class would be 
irreparably damaged were the transactions complained of herein consummated; and

    (c) whether the individual Defendants have breached their fiduciary and 
other common law duties owed by them to plaintiff and the other members of the 
Class.

  12. Plaintiff is committed to prosecuting this action and has retained 
competent counsel experienced in litigation of this nature. Plaintiff's claims 
are typical of the claims of the other members of the Class and plaintiff has 
the same interests as the other members of the Class. Accordingly, plaintiff is 
an adequate representative of the Class and will fairly and adequately protect 
the interests of the Class.

  13. Defendants have acted on grounds generally applicable to the Class with 
respect to the matters complained of herein, thereby making appropriate the 
relief sought herein with respect to the Class as a whole.
                 
                         SUBSTANTIVE ALLEGATIONS

  14. On or about August 17, 1998, Eastern and Waste Management, Inc. ("Waste 
Management") announced that they had reached a definitive merger agreement
whereby Waste Management would purchase all of the outstanding shares of Eastern
common stock for approximately $1.3 billion in Waste Management common stock.

<PAGE>
 
  15. Under the terms of the merger agreement, Eastern shareholders will receive
0.6406 shares of Waste Management common stock in exchange for each share of 
Eastern common stock held. Based upon Waste Management's closing price of 
$52.6875 per share on August 14, 1998, Eastern shareholders will receive 
approximately $33.75 of Waste Management common stock for each Eastern share, 
representing a premium of only 5.46% to Eastern's closing price of $32.00 per 
share on August 14, 1998.

  16. The merger consideration to be paid to Class members is unfair and grossly
inadequate because, among other things:

    (a) the consideration agreed upon did not result from an appropriate 
consideration of the value of Eastern as the Individual Defendants were 
presented with, and asked to evaluate, the proposed merger without any attempt 
to sufficiently ascertain the true value of Eastern through open bidding or a 
"market check" mechanism; 

    (b) the price received by Eastern shareholders does not reflect an adequate 
premium considering that: 

      I. On August 13, 1998, only two trading days prior to execution of the 
merger agreement, Eastern common stock was trading at $35.50 per share;

      II. Eastern common stock traded as high as $37.75 per share on July 24, 
1998, less than one month prior to execution of the merger agreement; and

      III. the intrinsic value of Eastern common stock is materially in excess 
of the amount offered giving due consideration to the Company's continuing 
economic improvement, ongoing operating efficiencies, and market share 
initiatives;

<PAGE>
 
    (c) On August 13, 1998, Eastern reported income for the second quarter of 
fiscal 1998 of $13.8 million, representing a 146% increase over operating income
                                          --------------------------------------
in the second quarter of fiscal 1997.
- ------------------------------------

  17. The Individual Defendants have thus far failed to announce any active 
auction or open bidding procedures best calculated to maximize shareholder value
and have, instead, agreed to the merger which will only serve to inhibit the 
maximization of shareholder value.

  18. The Individual Defendants were and are under a duty:

    (a) to fully inform themselves of Eastern's market value before taking, or 
agreeing to refrain from taking, action;

    (b) to act in the interests on the equity owners;

    (c) to maximize shareholder value;

    (d) to obtain the best financial and other terms when the Company's 
independent existence will be materially altered by a transaction;

    (e) to act in accordance with their fundamental duties of care and loyalty.

  19. By the acts, transactions and courses of conduct alleged herein, 
defendants, individually and as part of a common plan and scheme or in breach of
their fiduciary duties to plaintiff and the other members of the Class, are 
attempting unfairly to deprive plaintiff and other members of the Class of the 
true value of their investment in Eastern.

<PAGE>
 
  20. As a result of the actions of defendants, plaintiff and the other members 
of the Class have been and will be damaged in that they have not and will not 
receive their fair proportion of the value of Eastern's assets and businesses 
and will be prevented from obtaining appropriate consideration for their shares 
of Eastern's common stock.

   21. Unless enjoined by this Court, the defendants will continue to breach 
their fiduciary duties owed to plaintiff and the other members of the Class, and
may consummate the proposed transaction which will deprive the Class of its fair
proportionate share of Eastern's valuable assets and businesses, to the 
irreparable harm of the Class.

  22. Plaintiff and the Class have no adequate remedy at law.

  WHEREFORE, plaintiff demands judgment and preliminary and permanent relief, 
including injunctive relief, in her favor and in favor of the Class and against 
defendants as follows: 

  A. Declaring that this action is properly maintainable as a class action;

  B. Declaring and decreeing that the merger agreement was entered into in 
breach of the fiduciary duties of the Individual Defendants and is therefore 
unlawful and unenforceable;

  C. Enjoining defendants from proceeding with the merger agreement;

  D. Enjoining defendants from consummating the merger, or a business 
combination with a third party, unless and until the Company adopts and 
implements a procedure or process, such as an auction, to obtain the highest 
possible price for the Company;

<PAGE>
 
  E. Directing the Individual Defendants to exercise their fiduciary duties to 
obtain a transaction which is in the best interests of shareholders until the 
process for the sale or auction of the Company is completed and the highest 
possible price is obtained; 

  F. Rescinding, to the extent already implemented, the merger agreement or any 
of the terms thereof;

  G. Awarding plaintiff and the Class appropriate damages;

  H. Awarding plaintiff the costs and disbursements of this action, including 
reasonable attorneys' and experts' fees;

  I. Granting such other and further relief as this Court may deem just and 
proper.
