                                  SCHEDULE 13D


ITEM 1.           SECURITY AND ISSUER.

                  This  Statement on Schedule 13D (the  "Statement")  relates to
the Common Stock, $.02 par value (the "Common Stock"), of Environmental Services
of  America,  Inc.,  a  Delaware  corporation  (the  "Company").  The  principal
executive  offices of the  Company  are  located at 937 East  Hazelwood  Avenue,
Rahway, NJ
07065.

ITEM 2.           IDENTITY AND BACKGROUND.

                  This Statement is being filed by ERD Waste Corp.
("ERD").

                  ERD is a corporation  organized under the laws of the state of
Delaware  and is  principally  engaged in the business of waste  management  and
disposal.  The address of its  principal  business and  principal  office is 356
Veterans Memorial Highway, Commack, NY 11725.

                  (d) During the last five years,  ERD has not been convicted in
a criminal proceeding (excluding traffic violations and similar misdemeanors).

                  (e) During the last five years,  ERD has not been a party to a
civil proceeding of a judicial or administrative body of competent  jurisdiction
that  resulted  in ERD  being  subject  to a  judgment,  decree  or final  order
enjoining future violations of, or prohibiting or mandating  activities  subject
to,  Federal or State  securities  laws or finding any violation with respect to
such laws.

ITEM 3.           SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

                  The shares of the  Company's  Common  Stock were  acquired  as
consideration for ERD's making a $500,000 loan to the Company (the "Loan").  The
source of the funds for the Loan was the working capital of ERD.

ITEM 4.           PURPOSE OF TRANSACTION.

                  ERD and the Company  entered into a definitive  Agreement  and
Plan of Merger  dated  January 25, 1996 (the "Merger  Agreement"),  in which the
Company will merge with ENSA Acquisition Corp ("EAC"), a wholly-owned subsidiary
of ERD. As consideration  for the Company's  entering into the Merger Agreement,
ERD entered into a separate Securities Purchase Agreement with the Company dated
January 25, 1996 (the "Securities Purchase  Agreement").  Under the terms of the
Securities Purchase Agreement,  ERD acquired beneficial  ownership of the shares
of Common Stock to which this Statement  relates in consideration for ERD's Loan
to the Company. Upon the Company's

                                        3

<PAGE>



fulfillment  of  its  obligations  under  the  Securities   Purchase  Agreement,
including timely repayment of the Loan, ERD will return beneficial  ownership of
the shares of Common  Stock to the  Company.  The  effectiveness  of the planned
merger between EAC and the Company (the "Merger") is conditioned on the approval
of the Company's shareholders and other conditions.

                  (a)  ERD  plans  that  pursuant  to the  terms  of the  Merger
Agreement,  all shares of all classes of capital  stock of the  Company  will be
converted into the right to receive a payment based on the number of shares held
and cancelled upon the  effectiveness  of the Merger.  The payment per share for
each class of stock is as follows:

                  Common Stock                        $1.69
                  Series B Preferred Stock          $100.00
                  Series C Preferred Stock          $100.00


                  (b) ERD intends that EAC and the Company shall merge under the
terms of the Merger Agreement.

                  (c) Not applicable.

                  (d) ERD contemplates changes in the present board of directors
or  management  of the  Company  or  both,  changes  in the  number  or terms of
directors of the Company, and filling any existing vacancies on the board of the
Company in order to assume control of the Company if the Merger is effective.

                  (e) ERD  does  not  contemplate  any  material  change  in the
present capitalization or dividend policy of the Company.

                  (f) ERD does  not  contemplate  any  material  changes  in the
business  or  corporate  structure  of the Company at the time of filing of this
Statement.

                  (g) ERD does not  contemplate  any  changes  in the  Company's
charter, bylaws, or instruments corresponding thereto or other actions which may
impede the acquisition of control of the Company by any person.

                  (h) ERD  plans to  cause  all  shares  of all  classes  of the
Company's  stock to cease to be quoted on NASDAQ upon the  effectiveness  of the
Merger.

                  (i) ERD plans to cause all classes of all equity securities of
the  Company to become  eligible  for  termination  of  registration  pusuant to
Section 12(g)(4) of the Securities  Exchange Act of 1934 upon the  effectiveness
of the Merger.

                  (j) Not applicable.

                  Except as disclosed  in this Item 4, ERD has no other  current
plans or proposals which relate to or would result in any

         or would result in the creation of any  Encumbrance  as a result of, or
         under which there would be a material  default (with or without  notice
         or lapse of time,  or both) or right of  termination,  cancellation  or
         acceleration  of any  material  obligation  or the  loss of a  material
         benefit as a result of, the execution, delivery and performance by ENSA
         of this Agreement and the consummation of the transactions contemplated
         hereby,  except in the case of any  municipal,  county or township law,
         statute, rule, regulation, ordinance,  administrative decision, license

                                     - 11 -


<PAGE>



         aggregate,  reasonably be likely to have a Material  Adverse  Effect on
         ENSA and that would not impair, prohibit or prevent the consummation of
         the transactions  contemplated hereby, no consent,  order,  approval or
         authorization of, or declaration,  notice, registration or filing with,
         any court,  administrative  agency or commission or other  governmental
         authority   or   instrumentality   (each  a   "Governmental   Entity"),
         individual,   corporation,   partnership,   trust   or   unincorporated
         organization (together with Governmental Entities,  each a "Person") is
         required by or with respect to ENSA in connection  with the  execution,
         delivery and performance by ENSA of this Agreement and the consummation
         of the transactions contemplated hereby.

                  SECTION  3.6 SEC  Reports and  Financial  Statements  of ENSA.
Except as set  forth on  Section  3.6 of the ENSA  Disclosure  Letter,  ENSA has
timely filed with the SEC, and has heretofore provided to ERD, true and complete
copies  of,  all  forms,  reports,  schedules,  statements  and other  documents
required to be filed by it since the date ENSA became  subject to the  reporting
requirements  under  Section 13 of the Exchange Act or (as such  documents  have
been amended since the time of their filing, collectively, the "SEC Documents").
The SEC Documents,  including  without  limitation any financial  statements and
schedules included therein, at the time filed or, if subsequently amended, as so
amended,  (i) did not contain any untrue statement of a material fact or omit to
state a material  fact  required to be stated  therein or  necessary in order to
make the statements therein, in light of the circumstances under which they were
made,  not  misleading  and (ii)  complied  in all  material  respects  with the
applicable  requirements  of the  Exchange  Act and  the  applicable  rules  and
regulations of the SEC thereunder.  The financial statements of ENSA included in
SEC  Documents  comply  as to  form in all  material  respects  with  applicable
accounting  requirements and with the published rules and regulations of the SEC
with respect thereto,  have been prepared in accordance with GAAP,  applied on a
consistent  basis during the periods involved (except as may be indicated in the
notes thereto or, in the case of the unaudited statements,  as permitted by Form
10-Q of the SEC)  and  fairly  present  (subject,  in the case of the  unaudited
statements,  to customary  year-end audit adjustments) the financial position of
ENSA as at the dates thereof and the results of its operations and cash flows.

                  SECTION 3.7 Absence of Undisclosed Liabilities.  Except as and
to the extent set forth in ENSA's  Annual Report on Form 10-K for the year ended
December  31,  1994,  or as disclosed in the Form 10-Q for the nine month period
ended  September 30, 1995, or as disclosed in Section 3.7 of the ENSA Disclosure
Letter,  as of September 30, 1995, ENSA had no liabilities or obligations of any
nature, whether or not accrued,  contingent or otherwise, that would be required
by GAAP to be  reflected  on the  balance  sheet of ENSA  (including  the  notes
thereto) as of such

                                     - 12 -


<PAGE>



date.  Since  September  30,  1995,  ENSA has not incurred  any  liabilities  or
obligations of any nature, whether or not accrued,  contingent or otherwise, not
in the ordinary  course of business or which would have,  individually or in the
aggregate, a Material Adverse Effect.

                  SECTION  3.8  Accounts  Receivable.  The  accounts  receivable
disclosed  in SEC  Documents  as of September  30,  1995,  and,  with respect to
accounts receivable created since such date, disclosed in any subsequently filed
SEC  Documents,  or as  accrued on the books of ENSA in the  ordinary  course of
business  consistent  with past practices in accordance with GAAP since the last
filed SEC  Documents,  represent  and will  represent  bona fide claims  against
debtors for sales and other  charges,  are not  subject to  discount  except for
normal  cash and  immaterial  discounts,  and the amount  carried  for  doubtful
accounts and  allowances  disclosed in each of such SEC  Documents or accrued on
such books is  sufficient  to provide for any losses  which may be  sustained on
realization of the receivables.

                  SECTION 3.9   Title to Property.

                  (a) Except for the Permitted  Encumbrances  affecting personal
         property  described in Section  3.9(a) of the ENSA  Disclosure  Letter,
         ENSA has good and  valid  title to all of its  properties,  assets  and
         other rights that do not constitute  real  property,  free and clear of
         all Encumbrances,  except for such Encumbrances  securing  indebtedness
         that is not, in the  aggregate,  greater than $10,000.  ENSA owns,  has
         valid leasehold interests in or valid contractual rights to use, all of
         the assets,  tangible and  intangible,  used by, or  necessary  for the
         conduct of the business of, ENSA.

                  (b)  The  machinery,   tools,  equipment  and  other  tangible
         physical  assets of ENSA  (other than items of  inventory)  are in good
         working  order,  except  for  normal  wear and tear and except for such
         machinery,  tools, equipment and other tangible physical assets that do
         not, in the aggregate,  have a book value greater than $25,000,  in the
         aggregate,  and are in an operating condition sufficient to conduct the
         business of ENSA as now being conducted.

                  (c) Section  3.9(c) of the ENSA  Disclosure  Letter sets forth
         with  specific  reference to this Section each and every parcel of real
         property or interest in real estate  owned,  held under a lease or used
         by, or  necessary  for the conduct of the  business of, ENSA (the "Real
         Property").

                  (d)      ENSA:

                           (i) owns and has good and marketable title in fee
                  simple to the Real Property designated as "owned

                                     - 13 -

                  property" in Section 3.9(c) of the ENSA Disclosure Letter free
                  and clear of all Encumbrances,  except (A) minor imperfections
                  of title,  none of which,  individually  or in the  aggregate,
                  materially  detracts  from the value of or impairs  the use of
                  the affected  property or impairs the  operations of ENSA, (B)
                  liens  for  current  taxes  not yet due  and  payable  and (C)
                  Permitted   Encumbrances  affecting  such  Real  Property  and
                  reflected in Section 3.9(a) of the ENSA Disclosure Letter;

                         (ii) with respect to the Real  Property  designated  as
                  "leased  property"  in Section  3.9(c) of the ENSA  Disclosure
                  Letter,  and  except  as set  forth  in  such  Section,  is in
                  peaceful and undisturbed possession of the space and/or estate
                  under each lease under which it is a tenant,  and there are no
                  material defaults by it as tenant thereunder; and

                       (iii) has good and valid  rights of ingress and egress to
                  and from all the Real  Property  from and to the public street
                  systems for all usual street, road and utility purposes.

                  (e)  All  of  the  buildings,  structures,   improvements  and
         fixtures used by or useful in the business of ENSA,  owned or leased by
         ENSA,  are  in a  good  state  of  repair,  maintenance  and  operating
         condition and,  except as so disclosed and,  except for normal wear and
         tear,  there are no defects with respect thereto which would materially
         impair  the   day-to-day  use  of  any  such   buildings,   structures,
         improvements  or  fixtures  or which  would  subject  ENSA to  material
         liability under applicable law.

                  SECTION  3.10  Intellectual  Property.  Except as set forth on
Section 3.10 of the ENSA Disclosure Letter, ENSA owns or has valid rights to use
all patents,  patent rights,  trademarks,  trademark rights,  trade names, trade
name  rights,  copyrights,   service  marks,  trade  secrets,  applications  for
trademarks  and for service  marks,  know-how and other  proprietary  rights and
information  used or held for use in  connection  with the  business  of ENSA as
currently conducted or as contemplated to be conducted; there is no assertion or
claim challenging the validity of any of the foregoing which, individually or in
the aggregate,  could have a Material Adverse Effect on ENSA; the conduct of the
business of ENSA as  currently  conducted  does not conflict in any way with any
patent,  patent right,  license,  trademark,  trademark right, trade name, trade
name right,  service mark or copyright of any third party that,  individually or
in the aggregate,  could have a Material Adverse Effect on ENSA; and to the best
knowledge of ENSA, there are no infringements of any proprietary rights owned by
ENSA which,  individually  or in the  aggregate,  could have a Material  Adverse
Effect on ENSA.

                  SECTION 3.11 Tax Matters. Except as set forth in Schedule 3.11
to the ENSA Disclosure Letter:

                           (a) ENSA (or any predecessor)  and any  consolidated,
         combined,  unitary,  affiliated or aggregate  group for Tax purposes of
         which  ENSA  (or  any   predecessor)   is  or  has  been  a  member  (a
         "Consolidated  Group")  has,  to the best of ENSA's  knowledge,  timely
         filed all Tax  Returns  required  to be filed by it, has paid all Taxes
         shown on any Tax Return to be due in connection  with or respect to the
         periods or  transactions  covered by such Tax  Returns and has paid all
         other  Taxes as are due,  and has  provided  adequate  reserves  in its
         financial  statements for any Taxes that have not been paid, whether or
         not shown as being due on any Tax Returns.

                           (b) The reserves for Taxes (including deferred taxes)
         are  adequate  to  cover  all  Taxes  accruable   through  the  Closing
         (including Taxes being contested) in accordance with GAAP.

                           (c) To ENSA's  knowledge,  (i) no material  claim for
         unpaid  Taxes that are due and  payable  has become a lien  against the
         property of ENSA or is being  asserted  against ENSA or any member of a
         Consolidated  Group,  (ii) no  audit of any Tax  Return  of ENSA or any
         member of a  Consolidated  Group is being  conducted  by a Tax or other
         governmental  authority and there are no pending or threatened  audits,
         investigations or claims relating to any liability in respect of Taxes,
         and (iii) no  extension of the statute of  limitations  relating to any
         Taxes is in effect with respect to ENSA or any member of a Consolidated
         Group.  Within two weeks after the  execution of this  Agreement,  ENSA
         will supplement  Schedule 3.11 of the ENSA Disclosure Letter to provide
         the  following  information  with respect to ENSA as of the most recent
         practicable  date:  (i) the tax basis of ENSA in the  assets;  (ii) the
         amount of any net operating loss, net capital loss,  unused  investment
         or other  credits,  unused  foreign tax credits,  or excess  charitable
         contributions  allocable to ENSA; (iii) all material Tax elections with
         respect to Taxes  affecting  ENSA;  (iv) the amount of deferred gain or
         loss,   if  any,   allocable  to  ENSA  arising  out  of  any  deferred
         intercompany  transaction  (as such term is defined in Treas.  Reg. ss.
         l.1502-13); and (v) a list of all income Tax Returns filed on or behalf
         of ENSA which  indicates  those tax returns  that have been audited and
         the outcome of such  audits and a copy of all Tax  Returns  filed on or
         behalf of ENSA for the taxable  periods  ending after 1991.  Within two
         weeks  after the  execution  of this  Agreement,  ENSA will  notify ERD
         whether the remaining  representations contained in the provisions that
         follow in this  Section  3.11 are  accurate  or  whether  ENSA needs to
         supplement  Section 3.11 of the ENSA Disclosure  Letter to establish an
         exception with

                                     - 15 -

         respect to any of such  representations  or  warranties.  ENSA is not a
         party to any agreement, contract, arrangement or plan that would result
         after the Closing (taking into account the transactions contemplated by
         this Agreement),  separately or in the aggregate, in the payment of any
         "excess  parachute  payments" within the meaning of Section 280G of the
         Code.  ENSA is not a party to any tax  sharing  agreement  or any other
         agreement providing for payments by ENSA with respect to Taxes. ENSA is
         not  obligated   under  any   agreement   with  respect  to  industrial
         development  bonds or  other  obligations  with  respect  to which  the
         excludability  from gross  income of the  holder  for  federal or state
         income Tax purposes could be affected by the transactions  contemplated
         hereunder.  ENSA is not a "consenting corporation" under section 341(f)
         of the Code (or any corresponding  provision of state, local or foreign
         law).  ENSA is not  and has not  been a  United  States  real  property
         holding  corporation  (as  defined  in Section  897(c)(2)  of the Code)

Letter, are in full force and effect, all premiums with respect thereto covering
all periods up to and including  the Closing Date have been paid,  and no notice
of  cancellation  or  termination  has been  received  with  respect to any such

canceled or otherwise  terminated,  or made any written threat to ENSA to cancel
or otherwise  terminate,  its  relationship  with ENSA, or has at any time on or
after  September 30, 1995 decreased  materially its services or supplies to ENSA

services  of ENSA,  as the  case may be.  From and  after  the date  hereof,  no
customer which individually  accounted for more than 5% of ENSA's gross revenues

<PAGE>



to ENSA's  best  knowledge,  no such  customer  intends  to cancel or  otherwise
terminate its relationship with ENSA or to decrease  materially its usage of the
services or products of ENSA. ENSA has not knowingly breached,  so as to provide
a benefit to ENSA that was not intended by the parties,  any agreement  with, or
engaged in any  fraudulent  conduct with respect to, any customer or supplier of
ENSA.

                  SECTION 3.20 Absence of  Questionable  Payments.  Neither ENSA

unlawful contributions,  payments, gifts, or entertainment, or made any unlawful
expenditures relating to political activity to government officials or others or
established  or  maintained  any  unlawful or  unrecorded  funds in violation of
Section 30A of the Exchange Act. Neither ENSA nor any current director, officer,
agent,  employee  or other  Person  acting on behalf of ENSA,  has  accepted  or
received any unlawful contributions, payments, gifts, or expenditures.

                  SECTION 3.21  Information  Supplied.  None of the  information
supplied or to be supplied by ENSA for inclusion or  incorporation  by reference

statement  of a material  fact or omit to state any material  fact  necessary to

stockholders  to be held in  connection  with the  Merger,  contain  any  untrue
statement of a material  fact, or omit to state any material  fact  necessary to
correct  any  statement  in  any  earlier  communication  with  respect  to  the
solicitation of any proxy for such meeting of stockholders.  The Proxy Statement
will  comply as to form in all  material  respects  with the  provisions  of the
Exchange Act and the rules and regulations thereunder.


                  SECTION  3.22  Section  203 of the  DGCL Not  Applicable.  The
provisions of Section 203 of the DGCL will not, prior to the termination of this
Agreement,  apply  to this  Agreement,  the  Merger  or the  other  transactions
contemplated hereby.

                  SECTION 3.23 Disclosure. No representation or warranty by ENSA
in this  Agreement  contains or will contain any untrue  statement of a material
fact or omits or will omit to state any material fact necessary, in light of the

information  and take such other  actions as are  consistent  with the fiduciary
obligations  of  ENSA's  Board of  Directors,  and  such  actions  shall  not be
considered  a  breach  of  this  Section  5.7 or any  other  provision  of  this
Agreement. ENSA shall promptly advise ERD orally and in writing of any inquiries
or  Takeover  Proposals.  In the event the stock or assets of ENSA are sold to a
third party  making a Takeover  Proposal,  for  consideration  greater  than the
consideration  to be paid by ERD pursuant to this  Agreement,  ENSA shall pay to
ERD  the sum of  $100,000  as  liquidated  damages.  As used in this  Agreement,
"Takeover  Proposal"  shall mean any tender or exchange  offer,  proposal  for a
merger, consolidation or other business combination involving ENSA and made by a
Person  other  than ERD or any  proposal  or offer to  acquire  in any  manner a
substantial equity interest in, or a substantial  portion of the assets of, ENSA
other than the transactions contemplated by this Agreement, which is received by
ENSA prior to the termination of this Agreement.

Notwithstanding  anything  else in this  Agreement or the Note to the  contrary,

the Company at least five (5) days prior to the Maturity Date as in effect prior
to such postponement.

         Section 4.3 Interest.  The Company shall pay to Purchaser interest from
the date hereof accrued on the unpaid  principal amount of the Note from time to
time  outstanding at a rate of 8.5 % per annum,  which rate represents the prime

Rate"). Interest shall be payable in arrears on the Maturity Date.

         Section  4.4  Default  Interest.  Upon the  occurrence  and  during the
continuance of any Event of Default, the Company shall pay interest at the Prime
Rate plus 4% per annum on (i) the unpaid  principal amount of the Note from time
to time outstanding, payable on the maturity date and on demand, and (ii) to the
fullest extent permitted by law, the amount of any interest, fee or other amount

due until such amount shall be paid in full, payable in arrears on the date such
amount shall be paid in full, and on demand.

         Section 4.5 Optional  Prepayment.  The Company  shall have the right to
prepay  the  principal  amount  of the Note at any time in whole or from time to
time in  part,  with  accrued  interest  on the  amount  prepaid  to the date of
prepayment without premium or penalty therefor.

         Section 4.5 Subordination. The indebtedness of the Company to Purchaser
under the Note will be subordinated pursuant to a Subordination Agreement, among
the Company,  Purchaser and UJB (the "Subordination Agreement") in substantially
the form of Exhibit D hereto.

              Escrow of Shares; Grant of Proxy; Registration Rights

         Section  5.1  Escrow of  Shares.  (a)  Purchaser  agrees  that,  at the
Closing,  it shall  deliver to the Escrow  Agent,  pursuant  to the terms of the
Escrow  Agreement,  the Certificates  representing the Shares,  together with an
undated stock power for each such Certificate, duly executed in blank.

         (b) The parties agree that under the  circumstances  described  herein,
and subject to the terms of the Escrow  Agreement,  the Shares shall be released
from  escrow and either  delivered  to  Purchaser  or returned to the Company as
follows:

                (i) upon the  occurrence  of a Change of Control Event or on the
         Maturity Date following a Company Withdrawal  Decision,  if the Company
         shall not have paid in full all of its obligations  under the Note (the
         "Final  Payment") on or before such date all the Shares still in escrow
         shall be released from escrow and delivered to Purchaser;

                (ii)  if no  Change  of  Control  Event  or  Company  Withdrawal
         Decision shall have  occurred,  and the Company shall not have made the
         Final  Payment on or before  December 31,  1996,  250,000 of the Shares
         shall be released from escrow and delivered to Purchaser;

                (iii)  if no  Change  of  Control  Event or  Company  Withdrawal
         Decision shall have  occurred,  and the Company shall not have made the
         Final Payment on or before June 30, 1997, the remaining  250,000 Shares
         shall be released from escrow and delivered to Purchaser;

                (iv) if an Event of Default shall have  occurred,  other than an
         Event of Default based solely on the Company's  failure to pay when due
         any principal or interest on the Note,  and if Purchaser  exercises its
         option to declare  the Note  immediately  due and  payable,  all of the
         Shares still in escrow shall be released  from escrow and  delivered to
         Purchaser;

                (v) whenever the Final Payment is made,  all of the Shares still
         in escrow  shall be released  from escrow and  returned to the Company;
         provided, however, that if an event entitling Purchaser to the delivery
         of some or all of the Shares (the "Deliverable Shares") as set forth in
         any of clauses (i), (ii),  (iii) or (iv) of this subsection  5.1(b) has
         occurred prior to the making of the Final Payment, but the Escrow Agent
         is, pursuant to the terms of the Escrow  Agreement,  still holding such
         Deliverable  Shares,  such Deliverable Shares shall not be delivered to
         the Company  pursuant to this clause  5.1(b)(v),  but shall  instead be
         disposed  of  pursuant  to the  terms  of  Section  2(a) of the  Escrow
         Agreement;  and  provided,  further  that in no event  shall any of the
         Shares be  released  from  escrow and  returned  to the  Company  until
         Purchaser has received reasonably satisfactory assurances from UJB that
         at the time the Final Payment was made an event of default with respect
         to the UJB Loan, as defined therein, (x) had not

                                      - 6 -


<PAGE>



                occurred and was not  continuing,  and (y) would not result from
         the making of such Final Payment.

         (c) Any and all  dividends,  cash,  instruments,  securities  and other
property  from time to time  received,  receivable or otherwise  distributed  in
respect of or in exchange  for any of the Shares  while such Shares are still in
escrow,  shall be  delivered  to the Escrow  Agent and held in escrow  with such
Shares,  and either  delivered to  Purchaser or returned to the Company,  as the
case may be,  together  with such  Shares,  when such Shares are so delivered or
returned.

         Section 5.2 Grant of Proxy;  Irrevocability.  Purchaser  hereby  agrees
that in the event that a vote of the stockholders of the Company shall be taken,
or the written consent of the stockholders  shall be requested,  for any purpose
other than the  approval  of a Change of Control  Event or a Company  Withdrawal
Decision,  Purchaser  shall  appoint such Person or Persons as the Company shall
designate, proxy to vote all of the Shares that are still held in escrow and are
not Deliverable Shares as defined in Section 5.1(b)(v) above, in connection with
such vote or action by written consent.

         Section 5.3 Registration Rights.

         (a) If, at any time following the date of this  Agreement,  the Company
shall file a registration  statement (other than any  registration  statement on
Form S-4,  Form S-8, or any successor  form) with the SEC while any  Registrable
Shares (as hereinafter defined) are outstanding,  the Company shall give all the
then  holders of any  Registrable  Shares (the  "Eligible  Holders") at least 30
days' prior  written  notice of the filing of such  registration  statement.  If
requested by any Eligible  Holder in writing within 20 days after receipt of any
such notice,  the Company  shall,  at the Company's sole expense (other than the
fees and  disbursements of counsel for the Eligible Holders and the underwriting
discounts,  if any,  payable in respect of the  Registrable  Shares  sold by any
Eligible Holder),  register or qualify all or, at each Eligible Holder's option,
any portion of the  Registrable  Shares of any  Eligible  Holders who shall have
made such request,  concurrently with the registration of such other securities,
all to the  extent  necessary  to permit  the  public  offering  and sale of the
Registrable  Shares through the  facilities of all securities  exchanges and the
over-the-counter  markets on which the Company's securities are traded, and will
use its best efforts through its officers,  directors,  auditors, and counsel to
cause  such   registration   statement  to  become   effective  as  promptly  as
practicable.  Notwithstanding the foregoing,  if the managing underwriter of any
such  offering  shall advise the Company in writing  that,  in its opinion,  the
distribution  of all or a portion  of the  Registrable  Shares  requested  to be
included in the registration  concurrently  with the securities being registered
by the  Company  would  materially  adversely  affect the  distribution  of such
securities  by the Company for its own  account,  then any  Eligible  Holder who
shall have requested  registration of his or its Registrable Shares shall not be
entitled to have such  Eligible  Holder's  Registrable  Shares (or the  portions
thereof so designated by the managing underwriter) included in such registration
statement,  provided that no such exclusion or reduction shall be made as to any
Registrable  Shares  if any  securities  of the  Company  are  included  in such
registration  statement for the account of any person other than the Company and
any Eligible Holder unless the securities included in such

                                      - 7 -


<PAGE>



registration statement for such other person shall have been reduced pro rata to
the reduction of the  Registrable  Shares which were requested to be included in
such registration.  As used herein,  "Registrable  Shares" shall mean the Shares
and any other  securities  issued in  exchange  for,  upon  conversion  of, as a
dividend  on or  otherwise  in  respect  of such  Shares  which  have  not  been
previously  sold pursuant to a  registration  statement or Rule 144  promulgated
under the Act.

         (b) If, at any time after the Maturity  Date, the Company shall receive
a written  request from Eligible  Holders who in the aggregate own a majority of
the total number of Registrable Shares (the "Majority Holders"), to register the
sale of all or part of such Registrable  Shares,  the Company shall, as promptly
as  practicable,  prepare and file with the Commission a registration  statement
sufficient  to permit the public  offering  and sale of the  Registrable  Shares
through the  facilities of all  securities  exchanges  and the  over-the-counter
markets on which the  Company's  securities  are  traded,  and will use its best
efforts  through its officers,  directors,  auditors,  and counsel to cause such
registration statement to become effective as promptly as practicable; provided,
however,  that the Company shall only be obligated to file one such registration
statement.  All expenses  incurred in connection with such  registration  (other
than the  fees  and  disbursements  of  counsel  for the  Eligible  Holders  and
underwriting  discounts,  if any,  payable in respect of the Registrable  Shares
sold by the Eligible  Holders) shall be borne by the Company.  The Company shall
not be obligated to effect any  registration of its securities  pursuant to this
Section  5.3(b)  within  six  months  after  the  effective  date of a  previous
registration  statement prepared and filed in accordance with Section 5.3(a) (in
which  Registrable  Shares could have been  included).  Within ten business days
after receiving any request  contemplated  by this Section  5.3(b),  the Company
shall send written  notice to all the other  Eligible  Holders  advising each of
them that the  Company is  proceeding  with such  registration  and  offering to
include  therein  all or  any  portion  of  any  such  other  Eligible  Holder's
Registrable  Shares,  provided that the Company receives a written request to do
so from such  Eligible  Holder  within 20 days after receipt by him or it of the
Company's notice.

         (c) In the event of a  registration  pursuant to the provisions of this
Section  5.3, the Company  shall use its best  efforts to cause the  Registrable
Shares so registered to be registered or qualified for sale under the securities
or blue sky laws of such  jurisdictions  as the Eligible  Holder may  reasonably
request; provided, however, that the Company shall not by reason of this Section
5.3(c) be  required  to qualify to do  business  in any state in which it is not
otherwise  required to qualify to do  business  or to file a general  consent to
service of process.

         (d) The Company shall keep effective any  registration or qualification
contemplated by this Section 5.3 and shall from time to time amend or supplement
each  applicable   registration   statement,   preliminary   prospectus,   final
prospectus,  application, document, and communication for such period of time as
shall be required to permit the Eligible  Holders to complete the offer and sale
of the  Registrable  Shares  covered  thereby.  The Company shall in no event be
required to keep any such  registration or  qualification in effect for a period
in excess of six months  from the date on which the  Eligible  Holders are first
free to sell such Registrable Shares; provided, however, that, if the Company is
required to keep any such

                                      - 8 -


<PAGE>



registration or  qualification  in effect with respect to securities  other than
the  Registrable  Shares  beyond  such  period,  the  Company  shall  keep  such
registration or qualification in effect as it relates to the Registrable  Shares
for so long as such  registration  or  qualification  remains or is  required to
remain in effect in respect of such other securities.

         (e) In the event of a  registration  pursuant to the provisions of this
Section 5.3, the Company shall furnish to each Eligible  Holder such  reasonable
number  of  copies  of the  registration  statement  and of each  amendment  and
supplement  thereto (in each case,  including  all  exhibits),  such  reasonable
number of copies of each prospectus contained in such registration statement and
each supplement or amendment  thereto  (including each preliminary  prospectus),
all of which  shall  conform  to the  requirements  of the Act and the rules and
regulations  thereunder,  and such other  documents,  as any Eligible Holder may
reasonably  request to facilitate  the  disposition  of the  Registrable  Shares
included in such registration.

         (f) In the event of a  registration  pursuant to the provisions of this
Section 5.3, the Company shall furnish each Eligible  Holder of any  Registrable
Shares so registered  with an opinion of its counsel  (reasonably  acceptable to
the  Eligible  Holders) to the effect that (i) the  registration  statement  has
become effective under the Act and no order suspending the  effectiveness of the
registration  statement,  preventing or suspending  the use of the  registration
statement, any preliminary prospectus, any final prospectus, or any amendment or
supplement  thereto has been issued,  nor to the best  knowledge of such counsel
has  the  SEC or any  securities  or  blue  sky  authority  of any  jurisdiction
instituted or threatened  to institute any  proceedings  with respect to such an
order, and (ii) the registration  statement and the prospectus  included therein
and any supplements or amendments  thereto (except for financial  statements and
related schedules and documents  incorporated thereto by reference,  as to which
such counsel need express no opinion) comply as to form in all material respects
with the Act and the rules and regulations of the SEC thereunder.

         (g) In the event of a  registration  pursuant to the provisions of this
Section  5.3,  the  Company  and  each  Eligible   Holder  shall  enter  into  a
cross-indemnity  agreement and a contribution agreement, each in customary form,
with each  underwriter,  if any, and, if requested,  enter into an  underwriting
agreement containing  conventional  representations,  warranties,  allocation of
expenses,  and customary  closing  conditions,  including,  without  limitation,
opinions of counsel and accountants' cold comfort letters,  with any underwriter
who acquires any Registrable Shares.

         (h) The Company agrees that until all the Registrable  Shares have been
sold under a  registration  statement  or pursuant to Rule 144 under the Act, it
shall  keep  current  in filing  all  reports,  statements  and other  materials
required to be filed with the  Commission to permit  holders of the  Registrable
Shares to sell such securities under Rule 144.

         (i) The Company  will not grant to any persons the right to request the
Company to register any securities of the Company without the written consent of
the  Majority  Holders,  provided  that the Company may grant such  registration
rights to other persons so long as such rights are pari passu or  subordinate to
the rights of the holders of the Registrable Shares.

         Section 5.4     Indemnification

         (a) Subject to the  conditions  set forth below,  the Company agrees to
indemnify  and hold  harmless each  Eligible  Holder,  its officers,  directors,
partners,  employees, agents, and counsel, and each person, if any, who controls
any such person  within the meaning of Section 15 of the Act or Section 20(a) of
the Exchange Act, from and against any and all loss,  liability,  charge, claim,
damage,  and expense  whatsoever (which shall include,  for all purposes of this
Section  5.4,  without  limitation,  attorneys'  fees  and any  and all  expense
whatsoever  incurred  in  investigating,  preparing,  or  defending  against any
litigation,  commenced or threatened,  or any claim whatsoever,  and any and all
amounts paid in settlement of any claim or  litigation),  as and when  incurred,
arising out of,  based  upon,  or in  connection  with any untrue  statement  or
alleged untrue  statement of a material fact  contained (A) in any  registration
statement,  preliminary  prospectus,  or final  prospectus (as from time to time
amended and supplemented),  or any amendment or supplement thereto,  relating to
the sale of any of the  Registrable  Shares,  or (B) in any application or other
document  or  communication   (in  this  Section  5.4  collectively   called  an
"application")  executed  by or on behalf of the  Company or based upon  written
information  furnished by or on behalf of the Company filed in any  jurisdiction
in  order to  register  or  qualify  any of the  Registrable  Shares  under  the
securities  or blue sky laws  thereof,  or filed with the SEC or any  securities
exchange;  or any omission or alleged omission to state a material fact required
to be stated therein or necessary to make the statements therein not misleading,
unless such  statement or omission was made in reliance  upon and in  conformity
with written information  furnished to the Company with respect to such Eligible
Holder  by  or  on  behalf  of  such  person  expressly  for  inclusion  in  any
registration  statement,  preliminary  prospectus,  or final prospectus,  or any
amendment or supplement thereto, or in any application,  as the case may be. The
foregoing  agreement  to  indemnify  shall be in addition to any  liability  the
Company may otherwise have, including liabilities arising under the Note.

         If any  action is brought  against  any  Eligible  Holder or any of its
officers, directors, partners, employees, agents, or counsel, or any controlling
persons of such person (an  "indemnified  party") in respect of which  indemnity
may be sought  against the Company  pursuant to the  foregoing  paragraph,  such
indemnified party or parties shall promptly notify the Company in writing of the
institution  of such action (but the failure so to notify  shall not relieve the
Company from any  liability  under this Section  5.4(a) unless the Company shall
have been materially  prejudiced by such failure or relieve the Company from any
liability  other than  pursuant to this  Section  5.4(a)) and the Company  shall
promptly assume the defense of such action,  including the employment of counsel
(reasonably  satisfactory to such  indemnified  party or parties) and payment of
expenses.  Such indemnified  party or parties shall have the right to employ its
or their own counsel in any such case, but the fees and expenses of such counsel
shall  be at the  expense  of such  indemnified  party  or  parties  unless  the
employment of such counsel shall have been  authorized in writing by the Company
in  connection  with the defense of such  action or the  Company  shall not have
employed counsel reasonably satisfactory to such indemnified party or parties to
have charge of the defense of such action or such  indemnified  party or parties
shall have  reasonably  concluded  that there may be one or more legal  defenses
available to it or them or to other indemnified parties which are different from
or additional to those available to the Company, in any of which

                                     - 10 -


<PAGE>



events  such fees and  expenses  shall be borne by the  Company  and the Company
shall not have the right to direct the  defense of such  action on behalf of the
indemnified  party or  parties.  Anything in this  Section  5.4 to the  contrary
notwithstanding,  the Company shall not be liable for any settlement of any such
claim or  action  effected  without  its  written  consent,  which  shall not be
unreasonably  withheld.  The  Company  agrees  promptly  to notify the  Eligible
Holders of the commencement of any litigation or proceedings against the Company
or  any of its  officers  or  directors  in  connection  with  the  sale  of any
Registrable  Shares  or any  preliminary  prospectus,  prospectus,  registration
statement,  or amendment or supplement thereto,  or any application  relating to
any sale of any Registrable Shares.

         (b) Purchaser  agrees to indemnify and hold harmless the Company,  each
director of the  Company,  each officer of the Company who shall have signed any
registration  statement covering Registrable Shares held by the Purchaser,  each
other person,  if any, who controls the Company within the meaning of Section 15
of the Act or Section  20(a) of the Exchange  Act,  and its or their  respective
counsel,  to the same extent as the foregoing  indemnity from the Company to the
Eligible  Holders in Section  5.4(a),  but only with  respect to  statements  or
omissions, if any, made in any registration  statement,  preliminary prospectus,
or final  prospectus  (as from time to time  amended and  supplemented),  or any
amendment or supplement thereto, or in any application,  in reliance upon and in
conformity with written information furnished to the Company with respect to the
Purchaser by or on behalf of the  Purchaser  expressly for inclusion in any such
registration  statement,  preliminary  prospectus,  or final prospectus,  or any
amendment or supplement thereto,  or in any application,  as the case may be. If
any  action  shall be  brought  against  the  Company  or any  other  person  so
indemnified based on any such registration statement, preliminary prospectus, or
final prospectus, or any amendment or supplement thereto, or in any application,
and in respect of which  indemnity may be sought against the Purchaser  pursuant
to this Section 5.4(b),  the Purchaser shall have the rights and duties given to
the Company, and the Company and each other person so indemnified shall have the
rights and duties given to the indemnified parties, by the provisions of Section
5.4(a).

         (c)  To  provide  for  just  and  equitable  contribution,  if  (i)  an
indemnified party makes a claim for  indemnification  pursuant to Section 5.4(a)
or  5.4(b)  (subject  to the  limitations  thereof)  but it is  found in a final
judicial determination, not subject to further appeal, that such indemnification
may not be enforced in such case, even though this Agreement  expressly provides
for  indemnification in such case, or (ii) any indemnified or indemnifying party
seeks  contribution  under the Act,  the  Exchange  Act or  otherwise,  then the
Company (including for this purpose any contribution made by or on behalf of any
director  of the  Company,  any  officer  of the  Company  who  signed  any such
registration statement,  any controlling person of the Company, and its or their
respective counsel),  as one entity, and the Eligible Holders of the Registrable
Shares  included  in such  registration  in the  aggregate  (including  for this
purpose any contribution by or on behalf of an indemnified  party),  as a second
entity,  shall  contribute  to the losses,  liabilities,  claims,  damages,  and
expenses  whatsoever  to  which  any of them  may be  subject,  on the  basis of
relevant equitable  considerations such as the relative fault of the Company and
such  Eligible  Holders in  connection  with the facts  which  resulted  in such
losses,  liabilities,  claims, damages, and expenses. The relative fault, in the
case of an untrue statement,

                                     - 11 -


<PAGE>



alleged untrue statement, omission, or alleged omission, shall be determined by,
among other things,  whether such statement,  alleged  statement,  omission,  or
alleged  omission  relates to  information  supplied  by the  Company or by such
Eligible  Holders,  and the  parties'  relative  intent,  knowledge,  access  to
information,  and  opportunity  to correct or prevent  such  statement,  alleged
statement,  omission or alleged  omission.  The Company and the Purchaser  agree
that it would be unjust and  inequitable  if the  respective  obligations of the
Company and the Eligible Holders for contribution were determined by pro rata or
per capita allocation of the aggregate losses, liabilities, claims, damages, and
expenses (even if the Eligible  Holders and the other  indemnified  parties were
treated as one entity for such  purpose)  or by any other  method of  allocation
that does not reflect the equitable  considerations  referred to in this Section
5.4(c). In no case shall any Eligible Holder be responsible for a portion of the
contribution  obligation  imposed on all  Eligible  Holders in excess of its pro
rata  share  based on the  number  of shares  of  Common  Stock  owned by it and
included in such  registration  compared to the number of shares of Common Stock
owned by all  Eligible  Holders  and  included in such  registration.  No person
guilty of a fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution  from any person who is not guilty of
such fraudulent  misrepresentation.  For purposes of this Section  5.4(c),  each
person,  if any, who controls any Eligible  Holder within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act, and each officer,  director,
partner,  employee,  agent,  and counsel of each such Eligible Holder or control
person shall have the same rights to  contribution  as such  Eligible  Holder or
control  person and each person,  if any,  who  controls the Company  within the
meaning  of Section 15 of the Act or Section  20(a) of the  Exchange  Act,  each
officer of the Company who shall have  signed any such  registration  statement,
each director of the Company, and its or their respective counsel shall have the
same  rights  to  contribution  as the  Company,  subject  in  each  case to the
provisions  of this  Section  5.4(c).  Anything  in this  Section  5.4(c) to the
contrary notwithstanding, no party shall be liable for contribution with respect
to the settlement of any claim or action effected  without its written  consent.
This Section 5.4(c) is intended to supersede any right to contribution under the
Act, the Exchange Act or otherwise.

                                   ARTICLE VI

                  Representations and Warranties of the Company

         The Company represents and warrants to Purchaser that, except as is set
forth on the Company Disclosure  Schedule,  each of the statements  contained in
this Article VI is true, correct and complete.

         Section 6.1 Organization and Good Standing. The Company and each of its
Subsidiaries  is a  corporation  duly  organized,  validly  existing and in good
standing under the laws of the state of its  organization and has full corporate
power and  authority  to enter  into and carry out its  obligations  under  this
Agreement, the Escrow Agreement and the Note.

preceding  sentence at any time shall not constitute a waiver of the Purchaser's
right to exercise such option at any other time.

replace any invalid or unenforceable  term or provision with a term or provision

of the invalid and unenforceable term or provision,  and this Agreement shall be
enforceable  as so modified  after the  expiration  of the time within which the
judgment may be appealed.
