                                    RECITALS

         USE and the Company have determined that it is in the best interests
of their respective shareholders for USE to acquire the Company upon the terms
and subject to the conditions set forth in this Agreement.  In order to
effectuate the transaction, USE has organized the USE Merger Sub as a
wholly-owned subsidiary, and the parties have agreed, subject to the terms and
conditions set forth in this Agreement, to merge the USE Merger Sub with and
into the Company so that the Company continues as the surviving corporation.
As a result, the Company will become a wholly-owned subsidiary of USE, and each
of the Shareholders will be issued certain shares of common stock of USE.


                               TERMS OF AGREEMENT

         In consideration of the mutual representations, warranties, covenants

         or other employees, or establish, adopt, enter into or amend or take
         any action to accelerate any rights or benefits which any collective
         bargaining, bonus, profit sharing, trust, compensation, stock option,
         restricted stock, pension, retirement, deferred compensation,
         employment, termination, severance or other plan, agreement, trust,
         fund, policy or arrangement for the benefit of any directors, officers
         or employees;

<PAGE>   24


                 (g)      take any action other than in the ordinary course of
         business and in a manner consistent with past practice with respect to
         accounting policies or procedures;

                 (h)      pay, discharge or satisfy any existing claims,
         liabilities or obligations (absolute, accrued, asserted or unasserted,
         contingent or otherwise), other than the payment, discharge or
         satisfaction in the ordinary course of business and consistent with
         past practice of due and payable liabilities reflected or reserved
         against in its financial statements, as appropriate, or liabilities
         incurred after the date hereof in the ordinary course of business and
         consistent with past practice;

                 (i)      increase or decrease prices charged to its customers,
         except for previously announced price changes, or take any other
         action which might reasonably result in any material increase in the
         loss of customers through non-renewal or termination of service
         contracts or other causes; or

                 (j)      agree, in writing or otherwise, to take or authorize
         any of the foregoing actions or any action which would make any
         representation or warranty in Article III untrue or incorrect.


                                   ARTICLE V

                             ADDITIONAL AGREEMENTS

         5.1     FURTHER ASSURANCES.  Each party shall execute and deliver such
additional instruments and other documents and shall take such further actions
as may be necessary or appropriate to effectuate, carry out and comply with all
of the terms of this Agreement and the transactions contemplated hereby.

         5.2     COMPLIANCE WITH COVENANTS.  The Shareholders shall cause the
Company to comply with all of the respective covenants of the Company under
this Agreement.

         5.3     COOPERATION.  Each of the parties agrees to cooperate with the
other in the preparation and filing of all forms, notifications, reports and
information, if any, required or reasonably deemed advisable pursuant to any
law, rule or regulation or the rules of The NASDAQ Stock Market (or any
exchange on which the USE Common Stock may be listed) in connection with the
transactions contemplated by this Agreement and to use their respective best
efforts to agree jointly on a method to overcome any objections by any
Governmental Authority to any such transactions.

         5.4     RELEASE OF PERSONAL OBLIGATIONS.  USE shall cause the
Shareholders to be released from any personal liability under any loan or
obligation of the Company, and, in the event USE is





                                     24
<PAGE>   25

unable to obtain such releases, shall indemnify such Shareholders from any
amounts owed by them under any loan, guarantee or other obligation for which
releases from personal liability cannot be obtained.  USE shall take whatever
actions are reasonably necessary to obtain said releases, including, but not
limited to, the execution of security agreements or other such documents with
creditors of the Company to whom the Shareholders have personal liability in
order to substitute liability for said Shareholders.

         5.5     ACCESS TO INFORMATION.  From the date hereof to the Effective
Time, the Company shall (and shall cause its directors, officers, employees,
auditors, counsel and agents) to afford USE and USE's officers, employees,
auditors, counsel and agents reasonable access at all reasonable times to its
properties, offices, and other facilities, to its officers and employees and to
all books and records, and shall furnish such persons with all financial,
operating and other data and information as may be requested.  No information
provided to or obtained by USE shall affect any representation or warranty in
this Agreement.

         5.6     NOTIFICATION OF CERTAIN MATTERS.  The Shareholders shall give
prompt notice to USE of the occurrence or non-occurrence of any event which
would likely cause any representation or warranty contained herein to be untrue
or inaccurate, or any covenant, condition, or agreement contained herein not to
be complied with or satisfied.

         5.7     TAX MATTERS.  USE, the Company and the Shareholders will use
their respective best efforts to cause the Merger to qualify as a
reorganization under the provisions of Section 368(a) of the Code and do not
presently intend to take any action after the Merger is effected to cause the
Merger to lose its tax-free status; provided, however, that USE, the Company
and their respective Affiliates shall not be liable to the Shareholders for any
costs, damages, liabilities or other consequences of the failure of this
transaction to be treated as a tax-free reorganization and USE, the Company and
their respective Affiliates make no warranties, representations, guaranties or
other assurances that the transaction contemplated hereunder shall be treated
as a tax-free reorganization.  All parties hereto agree to file the Plan of
Merger with its respective federal income tax returns for the year in which the
Merger is effective, and to comply with the reporting requirements of Treasury
Regulation 1.368-3.

         5.8     CONFIDENTIALITY; PUBLICITY.  Except as may be required by law
or as otherwise permitted or expressly contemplated herein, no party hereto or
their respective Affiliates, employees, agents and representatives shall
disclose to any third party this Agreement or the subject matter or terms
hereof without the prior consent of the other parties hereto.  No press release
or other public announcement related to this Agreement or the transactions
contemplated hereby shall be issued by any party hereto without the prior
approval of the other parties, except that USE may make such public disclosure
which it believes in good faith to be required by law or by the terms of any
listing agreement with or requirements of a securities exchange (in which case
USE will consult with an officer of the Company prior to making such
disclosure).





                                     25
<PAGE>   26


         5.9     NO OTHER DISCUSSIONS.  The Company, the Shareholders, and
their respective Affiliates, employees, agents and representatives will not (i)
initiate, encourage the initiation by others of discussions or negotiations
with third parties or respond to solicitations by third persons relating to any
merger, sale or other disposition of any substantial part of the assets,
business or properties of the Company (whether by merger, consolidation, sale
of stock or otherwise) or (ii) enter into any agreement or commitment (whether
or not binding) with respect to any of the foregoing transactions.  The
Shareholders will immediately notify USE if any third party attempts to
initiate any solicitation, discussion or negotiation with respect to any of the
foregoing transactions.

         5.10    RESTRICTIVE COVENANTS.  In order to assure that USE will
realize the benefits of the Merger, each of Nevins, Meijer and Schroeder agrees
with USE that he will not:

                 (a)      for a period of five years from the Effective Time,
         directly or indirectly, alone or as a partner, joint venturer,
         officer, director, employee, consultant, agent, independent contractor
         or stockholder of any company or business, engage in the business of
         waste oil or water oil or water waste collection, disposal or
         recycling environmental remediation or emergency response waste
         clean-up (the "Environmental Services Business") in any county in any
         state in the United States in which USE or any of its subsidiaries
         conducts business at the time such Shareholder commences to engage in
         such activity; provided, however, that, the beneficial ownership of
         less  than five percent (5%) of the shares of stock of any corporation
         having a class of equity securities actively traded on a national
         securities exchange or over-the-counter market shall not be deemed, in
         and of itself, to violate the prohibitions of this Section;

                 (b)      for a period of five years from the Effective Time,
         directly or indirectly (i) induce any Person which is a customer of
         USE or any of its subsidiaries to patronize any business directly or
         indirectly in competition with the Environmental Services Business
         conducted by USE or any of its subsidiaries; (ii) canvass, solicit or
         accept from any Person which is a customer of USE or any of its
         subsidiaries, any such competitive business; or (iii) request or
         advise any Person which is a customer or supplier of USE or any of its
         subsidiaries to withdraw, curtail or cancel any such customer's or
         supplier's business with such entity;

                 (c)      for a period of five years from the Effective Time,
         directly or indirectly employ, or knowingly permit any company or
         business directly or indirectly controlled by him, to employ, any
         person who was employed by USE or any of its subsidiaries at or within
         the prior six months, or in any manner seek to induce any such person
         to leave his or her employment, however, that Midwest Custom
         Chemicals, Inc. ("MCC") shall be permitted to engage such of the
         Company or USE's employees who are currently providing services to MCC
         so long as the scope of, and the time devoted to, such activities for
         MCC are not more than what such employees provided to MCC
         historically, and provided further that the





                                     26
<PAGE>   27

         Company or USE is indemnified in full for any costs associated with
         MCC's engagement of such employees; and

                 (d)      at any time following the Effective Time, directly or
         indirectly, in any way utilize, disclose, copy, reproduce or retain in
         his possession the Company's proprietary rights or records, including,
         but not limited to, any of its customer lists.

The Shareholders agree and acknowledge that the restrictions contained in this
Section are reasonable in scope and duration and are necessary to protect USE
after the Effective Time.  The parties agree and acknowledge that the breach of
this Section will cause irreparable damage to USE and upon breach of any
provision of this Section, USE shall be entitled to injunctive relief, specific
performance or other equitable relief; provided, however, that, this shall in
no way limit any other remedies which USE may have (including, without
limitation, the right to seek monetary damages).

         Notwithstanding the restrictions set forth in this Section 9, in the
event USE's business and assets are liquidated pursuant to Chapter 7 of the
U.S. Bankruptcy Code, then the restrictions contained in this Section 9 shall
be without further force and effect.

         5.11    DUE DILIGENCE REVIEW AND ENVIRONMENTAL ASSESSMENT.  USE shall
be entitled to have conducted prior to Closing a due diligence review of the
assets, properties, books and records of the Company and an environmental
assessment of the Owned Properties and Leased Premises (hereinafter referred to
as "Environmental Assessment").  The Environmental Assessment may include, but
not be limited to, a physical examination of the Owned Property or Leased
Premises, and any structures, facilities, or equipment located thereon, soil
samples, ground and surface water samples, storage tank testing, review of
pertinent records, documents, and Licenses of the Company.  The Shareholders
shall provide USE or its designated agents or consultants with the access to
such property which USE, its agents or consultants require to conduct the
Environmental Assessment.  If the Environmental Assessment identifies
environmental conditions which require remediation or further evaluation under
the Environmental Laws or if the results of the Environmental Assessment or due
diligence review are otherwise not satisfactory to USE in its sole discretion,
then USE may elect not to close the transactions contemplated by this Agreement
in which case this Agreement shall be terminated.  USE's failure or decision
not to conduct any such Environmental Assessment shall not affect any
representation or warranty of the Shareholders under this Agreement.

         5.12    TRADING IN USE COMMON STOCK.  Except as otherwise expressly
consented to by USE, (i) from the date of this Agreement until the Effective
Time, neither the Company nor the Shareholders (nor any Affiliates thereof)
will directly or indirectly purchase or sell (including short sales) any shares
of USE Common Stock in any transactions effected on The NASDAQ Stock Market or
otherwise, or sell, transfer, pledge, dispose of or otherwise part with any
interest in or with respect to or in any other manner reduce their investment
risk with respect to any shares of USE Common Stock to be received pursuant to
this Agreement, and (ii) from the Effective Time until two years following the
Effective Time, the Shareholders (and all Affiliates of the Shareholders) will
not directly or indirectly sell or purchase or enter into any agreement,
contract or arrangement to sell or





                                     27
<PAGE>   28

purchase any put or call options or other derivative securities (including any
short sales) with respect to shares of USE Common Stock or enter into any other
agreements, contracts or arrangements providing for the alteration of their
investment risk with respect to any shares of USE Common Stock; provided,
however, that the foregoing shall not prohibit the Shareholders and their
Affiliates from making outright, unhedged sales or purchases of USE Common
Stock at any time.  Notwithstanding the foregoing, Nevins and Meijer shall have
the right to pledge or use for collateral their shares of USE Common Stock for
security on loans.

         5.13    TITLE INSURANCE AND SURVEYS.

                 (a)      Within 10 days following the date hereof, the Company
shall obtain and deliver to USE commitments (the "Commitments") issued by a
title insurance company acceptable to USE (the "Title Company") and dated on or
after the date hereof for the issuance of an ALTA Owners Policy of Title
Insurance (the "Title Policy") for each of the Owned Properties (and such of
the Leased Premises as USE may designate) in an amount acceptable to USE,
together with legible hard copies of all title exceptions reflected in the
commitments.  At USE's option, the Company shall deliver copies of previous
owner policies or other title evidence sufficient for USE to obtain the
Commitments directly from the Title Company or its agent.  The premium for the
Title Policy shall be paid by the Company.  The Title Policy shall be in the
amount designated by USE, showing fee simple title to the Owned Properties
vested in the Company at the Effective Time subject only to current real estate
Taxes not yet due and payable as of the Effective Time, and such other
covenants, conditions, easements, and exceptions to title as USE may approve in
writing (collectively, the "Permitted Exceptions"). The Commitments and the
Title Policy to be issued by the Title Company shall have all Standard and
General Exceptions deleted so as to afford full "extended form coverage" and
shall contain an ALTA Zoning Endorsements 3.1 (if available), contiguity (where
appropriate), survey, and such other endorsements as may be reasonably
requested by USE. At the Effective Time, the Company, the Shareholders and
their Affiliates shall deliver such affidavits or other instruments as the
Title Company may reasonably require to delete Standard and General Exceptions
and to provide the special endorsements required hereunder. The Company shall
cause the Commitments to be dated as of the Effective Time and cause the Title
Company to deliver the Title Policy at the Closing as directed by USE.

                 (b)      Within 20 days following the date hereof, the
Company shall deliver to USE and the Title Company an as-built plat of survey
of each of the Owned Properties and the Leased Premises (the "Surveys")
prepared by a registered land surveyor or engineer, licensed in the respective
states in which such properties are located, dated on or after the date hereof,
certified to USE, the Title Company, and such other entities as USE may
designate in writing to the Company prior to the Closing, and conforming to
current ALTA/ACSM Minimum Detail Requirements for Land Title Surveys,
sufficient to cause the Title Company to delete the standard printed survey
exception.  The cost of the Surveys or recertification of a prior Survey shall
be paid by the Company. Each Survey shall show access from the land to
dedicated roads and shall include a flood plain certification. Any survey may
be a recertification of a prior survey, provided that it meets the
above-described criteria.





                                     28
<PAGE>   29


                 (c)      If (i) any Commitment discloses a title exception
other than a Permitted Exception (an "Unpermitted Exception") or (ii) any
Survey discloses any encroachment, overlap, boundary dispute, or gap or any
other matter which renders title to any of the Owned Properties unmarketable or
reflects that any utility service to the improvements or access thereto does
not lie wholly within the applicable parcel of real property, or within an
encumbered easement for the benefit of such parcel of real property, or
reflects any other matter adversely affecting the use or improvements of such
parcel of real property  (a "Survey Defect"), then the Shareholders, prior to
the Closing, shall have the Unpermitted Exception removed from such Commitment
or the Survey Defect corrected or insured over by an appropriate title
insurance endorsement, all in a manner reasonably satisfactory to USE.

         5.14    CERTAIN TAX MATTERS.  The Shareholders shall duly prepare, or
cause to be prepared, and file, or cause to be filed, on a timely basis, all
Tax Returns for the Company for any period ending on or before the Effective
time.  The Shareholders shall provide such Tax Returns to USE for review at
least 60 days prior to their due date (including extensions where applicable).
The Shareholders shall not file any amended Tax Returns with respect to the
Company without the prior written consent of USE. The Shareholders and USE
shall provide the other party with such information and records and access to
such of its officers, directors, employees and agents as may be reasonably
requested by the other party in connection with the preparation of any tax
return or any audit or other proceeding relating to the Company.

         5.15    SHAREHOLDER VOTE.  Each of the Shareholders, in executing this
Agreement, consents as a shareholder of the Company to the Merger and the
transactions contemplated hereby, and waives notice of any meeting in
connection therewith, and hereby releases and waives all rights with respect to
the transactions contemplated hereby under any agreements relating to the sale,
purchase or voting of any capital stock of the Company.

         5.16    PAYOFF AMOUNTS.  Prior  to Closing, the Company shall request
and deliver to USE  payoff and estoppel letters from such holders of the
Company's outstanding Indebtedness as designated by USE, which letters shall
contain payoff amounts, per diem interest, wire transfer instructions and an
agreement to deliver, upon payment in full, UCC-3 termination statements,
satisfactions of mortgage and any original promissory notes or other evidences
of indebtedness marked canceled.

         5.17    EMPLOYMENT AGREEMENTS.  At the Closing, USE and Howard Nevins
shall enter into an employment agreement in the form attached hereto as Exhibit
5.18A.  At the Closing, USE and Henri Meijer shall enter into a consulting
agreement in the form attached hereto as Exhibit 5.18B.

         5.18    RIGHT OF FIRST REFUSAL.  Nevins and Meijer (the "MCC
Stockholders") own 100% of the issued and outstanding common stock of Midwest
Custom Chemicals, Inc., an Indiana corporation ("MCC").   The MCC Stockholders
agree that, if at any time after the date hereof, but before the second
anniversary of the Effective Date, the MCC Stockholders receive a bona fide
offer from a third party to acquire MCC (whether by acquisition of a
controlling stock interest in MCC,





                                     29
<PAGE>   30

acquisition of a substantial portion of MCC's assets or otherwise), then the
MCC Stockholders shall give written notice ("Notice of Offer") to USE within
five calendar days following the MCC Stockholders' receipt of such offer.  The
Notice of Offer shall set forth the price, the stock or assets that are the
subject of the offer, the name of the third party and the other terms and
conditions of such offer, including a signed copy of such offer, and shall
affirmatively state the MCC Stockholders' desire to sell MCC at such price and
on such other terms and conditions. For a period of 30 calendar days following
the receipt of the Notice of Offer (the "Option Period"), USE shall have the
option to elect to purchase MCC at the price and on the other terms and
conditions set forth in the Notice of Offer.  If USE gives written notice to
the MCC Stockholders within the Option Period of its election to purchase MCC,
the parties agree that the closing of the purchase and sale of such property
shall take place no later than the last to occur of (i) the date set forth in
the Notice of Offer, or (ii) 60 calendar days from the date that USE gives
notice to the MCC Stockholders of its intention to exercise its option, or such
other date as the parties may otherwise agree.  If USE fails to give written
notice of its election to purchase MCC within the Option Period, then the MCC
Stockholders shall have the right, for a period of 90 calendar days from the
expiration of the Option Period,  to close the purchase and sale or other
transfer of MCC with the third party named in the Notice of Offer on the terms
and conditions set forth in the Notice of Offer, free of this restriction. If
such closing has not occurred within such 90-day period, any sale of MCC shall
again be subject to the limitations contained herein. Further, if during such
90-day period the MCC Stockholders desire to change the terms of the
transaction identified in the Notice of Offer, then the MCC Stockholders shall
provide USE with a revised Notice of Offer and the procedure identified above
will apply to USE's consideration of the revised Notice of Offer.  If USE
exercises this right of first refusal, it may require MCC Stockholders to
transfer MCC to a nominee of USE.

         5.19    TRANSFER OF ASSETS.  At or before Closing, all of the LLC's
assets, tangible and intangible, real property and personalty, of whatsoever
kind or nature, including without limitation the Company Owned Properties and
the Assets, shall have been transferred to AES, free and clear of all liens,
mortgages, security interests and encumbrances other than those expressly
permitted by this Agreement.


                                   ARTICLE VI

               CONDITIONS TO THE OBLIGATIONS OF THE USE COMPANIES

President), certifying that such representations and warranties are true and
correct and that all such obligations have been complied with and performed.

         6.2     NO MATERIAL ADVERSE CHANGE OR DESTRUCTION OF PROPERTY.
Between the date hereof and the Effective Time, (i) there shall have been no
Material Adverse Change to the Company, (ii) there shall have been no adverse
federal, state or local legislative or regulatory change affecting in any
material respect the services, products or business of the Company, and (iii)

Section as of the Effective Date by the Secretary of the Company as being true,
correct and complete.

         6.4     OPINION OF COUNSEL.  The USE Companies shall have received an
opinion dated as of the Effective Date from counsel for the Company and the
Shareholders, in form and substance set forth as Exhibit 6.4 attached hereto.

         6.5     CONSENTS.  The Company shall have received consents to the
transactions contemplated hereby and waivers of rights to terminate or modify
any material rights or obligations of the Company from any Person from whom
such consent or waiver is required under any Contract or instrument as of a
date not more than ten days prior to the Effective Date, or who, as a result of
the transactions contemplated hereby, would have such rights to terminate or
modify such Contracts or instruments, either by the terms thereof or as a
matter of law.

         6.6     SECURITIES LAWS.  USE shall have received all necessary
consents and otherwise complied with any state or federal securities laws
applicable to the issuance of the USE Shares, in connection with the

Shareholders shall have delivered to USE all certificates evidencing the shares

threatened any action or proceeding by or before any court or other
governmental body which shall seek to restrain, prohibit, invalidate or collect

and which, in the judgment of USE, makes it inadvisable to proceed with the
Merger and other transactions contemplated hereby.

         6.10    BOARD APPROVAL.  The Board of Directors of USE shall have

         6.12    RELEASES.  Each of the Shareholders shall deliver to USE a
release (collectively, the "Releases") in such form as is reasonably
satisfactory to USE releasing all claims of any nature against USE and the
Company, if any, and any claims arising out of the Merger and the transactions
contemplated by this Agreement, provided that such Release shall not cover any
rights of the Shareholders against USE under this Agreement.


                                  ARTICLE VII

                        CONDITIONS TO THE OBLIGATIONS OF
                        THE COMPANY AND THE SHAREHOLDERS

         The obligations of the Company and the Shareholders to effect the
Merger shall be subject to the fulfillment at or prior to the Effective Time of
the following conditions, any or all of which may be waived in whole or in part
by the Company and the Shareholders:

         7.1     ACCURACY OF REPRESENTATIONS AND WARRANTIES AND COMPLIANCE WITH
OBLIGATIONS.  The representations and warranties of USE contained in this
Agreement shall be true and correct at and as of the Effective Time with the
same force and effect as though made at and as of that time except (i) for
changes specifically permitted by or disclosed pursuant to this Agreement, and
(ii) that those representations and warranties which address matters only as of
a particular date shall remain true and correct as of such date.  USE shall
have performed and complied with all of its obligations required by this
Agreement to be performed or complied with at or prior to the Effective Time.
USE shall have delivered to the Company and the Shareholders a certificate,
dated as of the Effective





                                     32
<PAGE>   33

Date, and signed by an executive officer, certifying that such representations
and warranties are true and correct and that all such obligations have been
complied with and performed.

         7.2     USE SHARES.  At the Closing, USE shall have issued all of the
USE Shares and shall have delivered to the Shareholders (i) certificates
representing the USE Shares issued to them hereunder, other than the Held Back
Shares, and (ii) copies of stock certificates representing the Held Back Shares
issued to them.

         7.3     NO ORDER OR INJUNCTION.  No court of competent jurisdiction or
other governmental body shall have issued or entered any order or injunction
restraining or prohibiting the transactions contemplated hereby, which remains
in effect at the time of Closing.

         7.4     ELECTION TO BOARD.  As soon as practicable following the date
of Closing, USE's Board of Directors shall have been expanded by one member and
Howard Nevins (or his designee) shall have been elected to fill such seat for a
term ending no earlier than the next annual meeting of the Stockholders of USE.


                                  ARTICLE VIII

                              REGISTRATION RIGHTS

         The Shareholders shall have the following registration rights with
respect to the USE Shares issued to them hereunder:

         8.1     REGISTRATION RIGHTS FOR USE SHARES; FILING OF REGISTRATION
STATEMENT. USE will utilize reasonable efforts to cause, as soon as practicable
following the Effective Time, but in any event within 30 calendar days after
the Effective Time, a registration statement to be filed under the Securities
Act or an existing registration statement to be amended for the purpose of
registering the USE Shares for resale by a Holder thereof (the "Registration
Statement").  For purposes of this Article, a person is deemed to be a "Holder"
of USE Shares whenever such person is the record owner of USE Shares.  USE will
use reasonable efforts to have the Registration Statement become effective and
cause the USE Shares to be registered under the Securities Act, and registered,
qualified or exempted under the state securities laws of such jurisdictions as
any Holder reasonably requests, as soon as is reasonably practicable.
Notwithstanding the foregoing, USE may delay (for a period not to exceed 30
calendar days) filing a Registration Statement, and may withhold (for a period
not to exceed 30 calendar days) efforts to cause the Registration Statement to
become effective, if USE determines in good faith that such registration is
likely to materially interfere with or materially affect the negotiation or
completion of any transaction that is actively being contemplated by USE at the
time the right to delay is exercised.

         8.2     EXPENSES OF REGISTRATION.  USE shall pay all expenses incurred
by USE in connection with the registration, qualification and/or exemption of
the USE Shares, including any





                                     33
<PAGE>   34

SEC and state securities law registration and filing fees, printing expenses,
fees and disbursements of USE's counsel and accountants, transfer agents' and
registrars' fees, fees and disbursements of experts used by USE in connection
with such registration, qualification and/or exemption, and expenses incidental
to any amendment or supplement to the Registration Statement or prospectuses
contained therein.  USE shall not, however, be liable for any sales, broker's
or underwriting commissions or other selling expenses incurred upon sale by any
Holder of any of the USE Shares.

         8.3     FURNISHING OF DOCUMENTS.  USE shall furnish to the Holders
such reasonable number of copies of the Registration Statement, such
prospectuses as are contained in the Registration Statement and such other
documents as the Holders may reasonably request in order to facilitate the
offering of the USE Shares.

         8.4     AMENDMENTS AND SUPPLEMENTS.  USE shall prepare and promptly
file with the SEC and promptly notify the Holders of the filing of such
amendments or supplements to the Registration Statement or prospectuses
contained therein as may be necessary to correct any statements or omissions
if, at the time when a prospectus relating to the USE Shares is required to be
delivered under the Securities Act, any event shall have occurred as a result
of which any such prospectus or any other prospectus as then in effect would
include an untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.  USE shall also
advise the Holders promptly after it shall receive notice or obtain knowledge
thereof, of the issuance of any stop order by the SEC suspending the
effectiveness of the Registration Statement or the initiation or threatening of
any proceeding for that purpose and promptly use its reasonable best efforts to
prevent the issuance of any stop order or to obtain its withdrawal if such stop
order should be issued.  If, after a Registration Statement becomes effective,
USE advises the Holders that USE considers it appropriate that the Registration
Statement be amended, the Holders shall suspend any further sales of the USE
Shares until USE advises the Holders that the Registration Statement has been
amended.

         8.5     DURATION.  USE shall maintain the effectiveness of the
Registration Statement until such time as USE reasonably determines, based on
an opinion of counsel, that the Holders will be eligible to sell all of the
Shares then owned by the Holders without the need for continued registration of
the shares, in the three month period immediately following the termination of
the effectiveness of the Registration Statement.  USE's obligations contained
in this Article VIII shall terminate on the first anniversary of the Effective
Date.

         8.6     FURTHER INFORMATION.  If USE Shares owned by a Holder are
included in any registration, such Holder shall furnish USE such information
regarding itself as USE may reasonably request and as shall be required in
connection with any registration, qualification or compliance referred to in
this Agreement.

                                   ARTICLE IX

                                INDEMNIFICATION

         9.1     AGREEMENT BY CERTAIN OF THE SHAREHOLDERS TO INDEMNIFY.  Nevins
and Meijer, jointly and severally, agree to indemnify and hold USE harmless
from and against the aggregate of all expenses, losses, costs, deficiencies,
liabilities and damages (including, without limitation, related counsel and
paralegal fees and expenses) incurred or suffered by USE arising out of or
resulting from (i) any breach of a representation or warranty made by the
Shareholders in or pursuant to this Agreement, (ii) any breach of the covenants
or agreements made by the Company or any Shareholder in or pursuant to this
Agreement, (iii) any audit, assessment or taxes arising from the matters set
forth on Schedule 3.19, or (iv) any inaccuracy in any certificate delivered by
the Company or any Shareholder pursuant to this Agreement (collectively,
"Indemnifiable Damages").  Without limiting the generality of the foregoing,
with respect to the measurement of Indemnifiable Damages, USE shall have the
right to be put in the same pre-tax consolidated financial position as it would
have been in had each of the representations and warranties of the Shareholders
hereunder been true and correct and had the covenants and agreements of the
Company and the Shareholders hereunder been performed in full.

         9.2     SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  Each of the
representations and warranties made by the Shareholders in this Agreement or
pursuant hereto shall survive the Closing.  No claim for the recovery of
Indemnifiable Damages arising out of a breach of any representation or warranty
may be asserted by USE against the Shareholders after such representations and
warranties shall thus expire, provided, however, that claims for Indemnifiable
Damages first asserted within the applicable period shall not thereafter be
barred.  Notwithstanding any knowledge of facts determined or determinable by
any party by investigation, each party shall have the right to fully rely on
the representations, warranties, covenants and agreements of the other parties
contained in this Agreement or in any other documents or papers delivered in
connection herewith.  Each representation, warranty, covenant and agreement of
the parties contained in this Agreement is independent of each other
representation, warranty, covenant and agreement.  Each of the representations
and warranties of USE and the Company shall expire at the Effective Time.

         9.3     SECURITY FOR THE SHAREHOLDERS' INDEMNIFICATION OBLIGATION.  As
security for the agreement by Nevins and Meijer to indemnify and hold USE
harmless as described in this Article at the Closing, Nevins and Meijer do each
hereby grant a first priority security interest in, and pledge and instruct USE
to set aside and hold, certificates representing the Held Back Shares issued
pursuant to this Agreement.  USE may set off against the Held Back Shares any
Indemnifiable Damages for which Nevins and Meijer may be responsible pursuant
to this Agreement, subject, however, to the following terms and conditions:

                 (a)      USE shall give written notice to Nevins and Meijer of
         any claim for Indemnifiable Damages or any other damages hereunder,
         which notice shall set forth (i) the amount of Indemnifiable Damages
         or other loss, damage, cost or expense





                                     35
<PAGE>   36

         which USE claims to have sustained by reason thereof, and (ii) the
         basis of such claim;

                 (b)      Such set off shall be effected on the later to occur
         on the expiration of 10 days from the date of such notice (the "Notice
         of Contest Period") or, if such claim is timely contested, the date
         the dispute is resolved;

                 (c)      After the Held Back Shares are registered and any
         restrictions on sale imposed under the Securities Act or otherwise are
         terminated, Nevins and Meijer may, not more than once during the nine
         (9) month period following the Effective Date, instruct USE in writing
         to sell some or all of the Held Back Shares and USE shall utilize
         reasonable efforts to promptly sell the Held Back Shares following
         such written instruction and the net proceeds thereof shall be
         substituted for such Held Back Shares in any set off to be made by USE
         pursuant to any claim hereunder; and

                 (d)      For purposes of this Article, the shares of USE
         Common Stock not sold as provided in clause (c) of this Section shall
         be valued at the Average Closing Price.

         9.4     VOTING OF AND DIVIDENDS ON THE HELD BACK SHARES.  Except with
respect to shares transferred pursuant to the foregoing right of setoff (and in
the case of such shares, until the same are transferred), all Held Back Shares
shall be deemed to be owned by Nevins and Meijer and Nevins and Meijer shall be
entitled to vote the same; provided, however, that, there shall also be
deposited with USE subject to the terms of this Article, all shares of USE
Common Stock issued to Nevins and Meijer as a result of any stock dividend or
stock split and all cash issuable to Nevins and Meijer as a result of any cash
dividend, with respect to the Held Back Shares.  All stock and cash issued or
paid upon Held Back Shares shall be distributed to the person or entity
entitled to receive such Held Back Shares together with such Held Back Shares.

         9.5     DELIVERY OF HELD BACK SHARES.  USE agrees to deliver to Nevins
and Meijer no later than nine (9) months following the Effective Date any Held
Back Shares then held by it (or proceeds from the Held Back Shares) unless
there then remains unresolved any claim for Indemnifiable Damages or other
damages hereunder as to which notice has been given, in which event any Held
Back Shares remaining on deposit (or proceeds from the sale of Held Back
Shares) after such claim shall have been satisfied shall be returned to Nevins
and Meijer promptly after the time of satisfaction.

         9.6     NO BAR; WAIVER.  If the Held Back Shares are insufficient to
set off any claim for Indemnifiable Damages made hereunder (or have been
delivered to Nevins and Meijer prior to the making or resolution of such
claim), then USE may take any action or exercise any remedy available to it by
appropriate legal proceedings to collect the Indemnifiable Damages.  Nevins and
Meijer hereby waive any rights to contribution or any similar rights they may
have against the Company as of a result of their agreement to indemnify USE
under this Article IX.

                             SECURITIES LAW MATTERS

         The parties agree as follows with respect to the sale or other
disposition after the Effective Time of the USE Shares:

         10.1    DISPOSITION OF SHARES.  The Shareholders represent and warrant
that the shares of USE Common Stock being acquired by them hereunder are being
acquired and will be acquired for their own respective accounts and will not be
sold or otherwise disposed of, except pursuant to (a) an exemption from the
registration requirements under the Securities Act, which does not require the
filing by USE with the SEC of any registration statement, offering circular or
other document, in which case, the Shareholders shall first supply to USE an
opinion of counsel (which counsel and opinions shall be satisfactory to USE)
that such exception is available, or (b) an effective registration statement
filed by USE with the SEC under the Securities Act.

         10.2    LEGEND.  The certificates representing the USE Shares shall
bear the following legend:

         THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
         TRANSFERRED OR OTHERWISE DISPOSED OF BY THE HOLDER EXCEPT (A) PURSUANT
         TO AN EFFECTIVE REGISTRATION STATEMENT FILED UNDER THE SECURITIES ACT
         OF 1933, AS AMENDED (THE "ACT"), AND IN COMPLIANCE WITH APPLICABLE
         SECURITIES LAWS OF ANY STATE WITH RESPECT THERETO, (B) IN ACCORDANCE
         WITH RULE 145(D) UNDER THE ACT OR (C) IN ACCORDANCE WITH AN OPINION OF
         COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER THAT AN
         EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE, AND ALSO MAY NOT BE
         SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF BY THE HOLDER WITHOUT
         COMPLIANCE WITH ANY APPLICABLE RULES OF THE SECURITIES AND EXCHANGE
         COMMISSION.

USE may, unless a registration statement is in effect covering such shares,
place stop transfer orders with its transfer agents with respect to such
certificates in accordance with federal securities laws.  The Shareholders each
agree that all sales of the USE Common Stock shall be made in compliance with
Rule 145(d) under the Act, and that the Shareholders shall make such sales
through Gaines, Berland, Inc. and/or other parties designated by USE in
brokered transactions, provided that if such designated broker is not making a
good faith effort to sell such shares of USE Common Stock then, upon written
notice to USE, the Shareholders may otherwise sell such shares in accordance
with Rule 145(d).

the Executive or his legal representatives shall be entitled to that portion of

inability to perform his duties and responsibilities as provided herein due to
his death, physical or mental disability or sickness extending for, or
reasonably expected to extend for, greater than 180 days.  If the Executive

Executive shall be deemed for purposes of this Agreement to have been

hereunder from and after such resignation or termination.

                 (b)      Without Cause.  At any time during the Term, the
Company shall have the right to terminate the Term and to discharge the
Executive without cause effective upon delivery of written notice to the
Executive.  The Executive shall be entitled to continue to receive the portion
of his salary when and as the same would have been due and payable hereunder

entitled to such payments as long as he is in compliance with the provisions of
both Section 9.

         9.      RESTRICTIVE COVENANTS.  The Executive agrees with the Company

that, the beneficial ownership of less  than five percent (5%) of the shares of

a national securities exchange or over-the-counter market shall not be deemed,
in and of itself, to violate the prohibitions of this Section;

person to leave his or her employment, provided; however, that the Executive's
affiliate, Midwest Custom Chemicals, Inc.  ("MCC") shall be permitted to engage
such of AES' employees who are currently providing services to MCC so long as
the scope of, and the time devoted to, such activities for MCC are not more
than what such employees provided to MCC historically, and provided further
that AES is indemnified in full for any costs associated with MMC's engagement
of such employees; and

                 (d)      at any time following the date hereof, use for his
own account, or release or divulge or make known for any unauthorized reason or
purpose, any information not otherwise publicly available whatsoever relating

shall include, but is not limited to, customer, contractor or supplier lists,
trade secrets, proprietary services, processes, software, hardware and other

carry out his assigned responsibilities and duties during the term of
employment.

The Executive agrees and acknowledges that the restrictions contained in this
Section are reasonable in scope and duration and are necessary to protect the

injunctive relief, specific performance or other equitable relief; provided,
however, that, this shall in no way limit any other remedies which the Company
may have (including, without limitation, the right to seek monetary damages).

         Notwithstanding the restrictions set forth in this Section 9, in the
event the Company's business and assets are liquidated pursuant to Chapter 7 of
the U.S. Bankruptcy Code, then the restrictions contained in this Section 9
shall be without further force and effect.

         10.     DOCUMENTS AND INFORMATION.  The Executive will, at all times
upon request, fully advise and inform the Board of the Company with respect to
all matters which the Executive may





                                      4

                      EXHIBIT B - INCENTIVE COMPENSATION



        1.      Cash Bonus.  

                During the Term, the Company shall pay to the Executive a cash
bonus on the terms described below.  The cash bonus shall be equal to (a) 5%,
multiplied by (b) the difference between (a) the pretax earnings after bonus
(calculated in accordance with GAAP, except as modified below) of the
USE-Environmental Division for the subject fiscal year (or shorter fiscal
period, as applicable), minus (b) the Base Earnings for the subject fiscal
period, such difference being referred to herein as the "Incremental Earnings." 
As used herein, (a) "USE-Environmental Division" shall mean American
Enviro-Services, Inc. ("AES") and any Environmental Services Businesses
acquired (whether by merger, share exchange or asset acquisition) by the
Company and operated under the control and supervision of the Executive, (b)
"Base Earnings" shall mean (i) $450,000 (plus, if applicable, the pre-tax
earnings of any Environmental Services Business acquired by the Company) for
the fiscal period commencing August 1, 1997 and ending January 31, 1998, (ii)
$800,000  (plus, if applicable, the pre-tax earnings of any Environmental
Services Business acquired by the Company) for the fiscal year ending January
31, 1998 and (iii) for all other fiscal periods, the pre-tax earnings of the
USE-Environmental Division (including, if applicable, the pre-tax earnings of
any Environmental Services Business acquired by the Company) for the
immediately preceding completed comparable fiscal period but in no event less
than $800,000 (for example: for purposes of calculating the cash bonus payable
for the fiscal year ending January 31, 2000, the Base Earnings would be the
pre-tax earnings for the fiscal year commencing February 1, 1998 , and ending
January 31, 1999, and for purposes of calculating the cash bonus for the
six-month fiscal period ending July 31, 2001 (presuming the Term expires August
15, 2001), the Base Earnings would be the pre-tax earnings for the fiscal
period commencing February 1, 2000 and ending July 31, 2000).  

        For purposes of calculating pre-tax earnings, and whether or not in
accordance with GAAP, (a) any increase in the earnings of any Environmental
Services Business acquired by AES shall be included in calculating the bonus
payable hereunder only if such earnings are directly attributable to the
management efforts of the Executive, as reasonably determined by the Company,
and (b) such earnings shall be reduced by (i) the amount of any depreciation
allowance for any capital expenditures incurred by the Company (or any of its
affiliates) on behalf of the USE-Environmental Division and which expenditures
contributed to the increase in such earnings, (ii) a reasonable allocation of
overhead expenses incurred by the Company (or its affiliates) on behalf of the
USE - Environmental Division, not to exceed 5% of the USE - Environmental
Division revenues for such period, (iii) actual expenses incurred by the
Company (or its affiliates) on behalf of the USE - Environmental Division, (iv)
an interest factor for all advances by the Company (or its affiliates) to, or
for the benefit of the USE - Environmental Division, at a rate equal to the
Company's borrowing rate, (v) amortization of the Company's (or its
affiliates') intangibles for the AES acquisition (based on a 15-year
amortization), and (vi) to the extent mutually agreed upon by the Company and
the Executive, amortization of the Company's (or its affiliates') intangibles
for future acquisitions (and 


                                      1
<PAGE>   12

with respect to future acquisitions accounted for using the pooling method of

described below.  The number of stock options granted shall equal to the
greater of (a) the number of options granted to other executives of the Company

Company's Board of Directors, or (b) an amount of options equal to (i) the
Incremental Earnings for the subject fiscal period, divided by (ii) $10.00 (for
example: if the Incremental Earnings for the period are $1 million, then the
Executive shall be granted options to acquire 100,000 shares).  All

                The cash bonus and the stock option grant, if earned, shall be

the Executive resigns or otherwise terminates his employment, then the
Executive shall not be entitled to any cash bonus or stock option grant for all
or any portion of the fiscal year during which such termination took place.  If
the Company terminates the Term without cause, the Executive shall be entitled
to receive the cash bonus and stock option grant, if otherwise earned, for the
portion of the current fiscal year prior to the date on which such termination
took place.  

        5.      Calculation.  

                All calculations hereunder shall be performed by the Company's
certified public accountants, and shall be binding upon the Company and the
Executive.

Date:        August 4, 1997

             U.S. ENERGY SYSTEMS, INC. TO ACQUIRE AMERICAN ENVIRO-SERVICES, INC.

     West Palm Beach, FL -- August 4, 1997 -- U.S. Energy Systems, Inc. (Nasdaq
Symbol USEY) announced today that it will acquire American Enviro-Services, Inc.
of Newburgh, Indiana, which provides multifaceted environmental services
primarily in the Midwestern United States. American Enviro-Services, Inc. will
continue to operate, as a wholly owned subsidiary of U.S. Energy Systems, Inc.,
and will be the nucleus of a new division called USE-Environmental. The value of
the transaction is approximately $3.3 million.

     American Enviro-Services is the leading company in its region in the
collection and recycling of used motor and industrial oils. The company's end
product is on-specification fuel used in industrial furnaces, boilers, and
electric cogeneration systems. In addition to its recycled oil operation,
American Enviro-Services provides industrial waste water treatment and 24-hour
Emergency Response services throughout the Midwestern United States. American
Enviro-Services also provides complete environmental consulting including full
scale project development and engineering services, underground tank removal and
installation, bioremediation, as well as Phase I, II and III environmental
assessments.

     Richard H. Nelson, President and CEO of U.S. Energy Systems, stated, "The
formation of our environmental division -- and the acquisition of American
Enviro-Services as the focal point of that division -- adds an important
dimension to our company. Not only do we expect the new division to contribute
significantly to revenues, but the environmental consulting and engineering
services will provide us with critical in-house capability for our independent
power and cogeneration business. In addition, many of these projects will be
able to benefit from the use of recycled oil. In a recent speech, U.S.
Department of Energy Secretary Federico Pena stated that, 'Environmental issues
are inseparable from electricity restructuring.' We concur with the Secretary's
statement, and our company is firmly committed to the environment. The talent
and expertise we are gaining through the acquisition of

American Enviro-Services will help insure that present and future projects
maintain that commitment and focus."

     Howard A. Nevins, President and CEO of American Enviro-Services, will
continue in that position as well as being named Executive Vice President of
U.S. Energy Systems, Inc. in charge of the new environmental division. "Joining
the U.S. Energy Systems team will allow operations to expand faster over a
larger geographic area through internal growth and acquisitions. We intend to be
a major player nationwide in all segments of our industry, and especially in the
recycled oil industry." Nevins noted that there are currently in excess of 2.5
billion gallons of used oil generated in the United States annually. "If not
properly recycled," Nevins continued, "a major portion of this used oil would
otherwise find its way into our rivers and streams. Properly recycled, however,
used oil becomes an inexpensive, efficient, and clean burning fuel."

     U.S. Energy Systems, Inc. develops, owns and operates cogeneration and
independent power projects throughout the United States. At present it owns
interests in plants in Utah, New Hampshire and Nevada, and is in the process of
developing and/or acquiring additional power plants in several other states and
the Caribbean. The Company is also participating in the development of a large
district heating facility, known as Reno Energy, which will utilize geothermal
heat to serve parts of the city of Reno, Nevada.
